Case-control study. To determine whether serum metal ion levels and erythrocyte chromium levels in adolescents with stainless steel spinal instrumentation are elevated when compared with 2 control groups. Instrumented spinal arthrodesis is a common procedure to correct scoliosis. The long-term consequences of retained implants are unclear. Possible toxic effects related to raised metal ion levels have been reported in the literature. Thirty patients who underwent posterior spinal arthrodesis with stainless steel instrumentation for scoliosis (group 1) were included. Minimum postoperative duration was 3 years. Serum chromium, molybdenum, iron, and ferritin levels were measured. Participants with elevated above normal serum chromium levels (n = 11) also underwent erythrocyte chromium analysis. Comparisons were made with 2 control groups; 10 individuals with scoliosis with no spinal surgery (group 2) and 10 volunteers without scoliosis (group 3). All control group participants underwent serum and erythrocyte analysis. Elevated above normal serum chromium levels were demonstrated in 11 of 30 (37%) group 1 participants. Elevated serum chromium levels were demonstrated in 0 of 10 participants (0%) in group 2 and 1 of 10 (10%) in group 3. There was a statistically significant elevation in serum chromium levels between group 1 and group 2 participants (P = 0.001). There was no significant association between groups 1, 2, and 3 for serum molybdenum, iron, and ferritin levels. Erythrocyte chromium measurements were considered within the normal range for all participants tested (n = 31). Raised serum chromium levels were detected in 37% of patients following instrumented spinal arthrodesis for correction of scoliosis. This new finding has relatively unknown health implications but potential mutagenic, teratogenic and carcinogenic sequelae. This is especially concerning with most scoliosis patients being adolescent females with their reproductive years ahead.

The aim of this study was to evaluate nutritional status in children who underwent hematopoietic stem cell transplant compared with a healthy control group. A secondary aim was to utilize mid-upper arm circumference as a measure of nutritional status in these groups of children. Our study group included 40 children (18 girls, 22 boys) with mean age of 9.2 ± 4.6 years (range, 2-17 y) who underwent hematopoietic stem cell transplant. Our control group consisted of 20 healthy children (9 girls, 11 boys). The children were evaluated at admission to the hospital and followed regularly 3, 6, 9, and 12 months after discharge from the hospital. In the study group, 27 of 40 patients (67.5%) received nutritional support during hematopoietic stem cell transplant, with 15 patients (56%) receiving enteral nutrition, 6 (22%) receiving total parenteral nutrition, and 6 (22%) receiving enteral and total parenteral nutrition. Chronic malnutrition rate in the study group was 47.5% on admission to the hospital, with the control group having a rate of 20%. One year after transplant, the rate decreased to 20% in the study group and 5% in the control group. The mid-upper arm circumference was lower in children in the study group versus the control group at the beginning of the study (P < .05). However, there were no significant differences in mid-upper arm circumference measurements between groups at follow-up examinations (P > .05). During follow-up, all anthropometric measurements increased significantly in both groups. Monitoring nutritional status and initiating appropriate nutritional support improved the success of hematopoietic stem cell transplant and provided a more comfortable process during the transplant period. Furthermore, mid-upper arm circumference is a more sensitive, useful, and safer parameter that can be used to measure nutritional status of children who undergo hematopoietic stem cell transplant.

The aim of this preliminary prospective RCT was to histologically evaluate peri-implant soft tissues around titanium abutments treated using different cleaning methods. Sixteen patients were randomized into three groups: laboratory customized abutments underwent Plasma of Argon treatment (Plasma Group), laboratory customized abutments underwent cleaning by steam (Steam Group), and abutments were used as they came from industry (Control Group). Seven days after the second surgery, soft tissues around abutments were harvested. Samples were histologically analyzed. Soft tissues surrounding Plasma Group abutments predominantly showed diffuse chronic infiltrate, almost no acute infiltrate, with presence of few polymorphonuclear neutrophil granulocytes, and a diffuse presence of collagenization bands. Similarly, in Steam Group, the histological analysis showed a high variability of inflammatory expression factors. Tissues harvested from Control Group showed presence of few neutrophil granulocytes, moderate presence of lymphocytes, and diffuse collagenization bands in some sections, while they showed absence of acute infiltrate in 40% of sections. However, no statistical difference was found among the tested groups for each parameter (p > 0.05). Within the limit of the present study, results showed no statistically significant difference concerning inflammation and healing tendency between test and control groups.

Carbon nanoparticles show significant lymphatic tropism and can be used to identify lymph nodes surrounding mid-low rectal tumors. In this study, we analyzed the effect of trans anal injection of a carbon nanoparticle suspension on the outcomes of patients with mid-low rectal cancer who underwent laparoscopic resection. We collected the data of 87 patients with mid-low rectal cancer who underwent laparoscopic resection between November 2014 and March 2015 at Cancer Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College. For 35 patients in the experimental group, the carbon nanoparticle suspension was injected transanally into the submucosa of the rectum around the tumor 30 min before the operation; 52 patients in the control group underwent the operation directly without the injection of carbon nanoparticle suspension. We then compared the operation outcomes between the two groups. In the experimental group, the rate of incomplete mesorectal excision was lower than that in the control group, but no significant difference was found (2.9% vs. 7.7%, P = 0.342). The distance between the tumor and the circumferential resection margin was 5.8 ± 1.4 mm in the experimental group and 4.8 ± 1.1 mm in the control group (P = 0.001). The mean number of lymph nodes removed was 28.2 ± 9.4 in the experimental group and 22.7 ± 7.3 in the control group (P = 0.003); the mean number of lymph nodes smaller than 5 mm in diameter was 10.1 ± 7.5 and 4.5 ± 3.7, respectively (P < 0.001). Three patients in the experimental group received lateral lymph node resection. Among the three patients, we retrieved three nodes (one stained node) from the first patient, three nodes (two stained nodes) from the second patient, and two nodes (no stained nodes) from the third patient. Injecting a carbon nanoparticle suspension improved the outcomes of patients who underwent laparoscopic resection for mid-low rectal cancer; it also improved the accuracy of pathologic staging. Moreover, for selected patients, this technique narrowed the scope of lateral lymph node dissection.

Background: Ulnar collateral ligament reconstruction (UCLR) has become an increasingly common procedure among Major League Baseball (MLB) pitchers. The long-term effects of this procedure on the career of an MLB pitcher are largely unknown. Purpose/Hypothesis: The purpose of this study was to determine why and when MLB pitchers who underwent UCLR during their careers retired from baseball as compared with controls. We hypothesized that pitchers who underwent UCLR are no more likely than control pitchers to retire from elbow or shoulder problems. Study Design: Cross-sectional study; Level of evidence, 3. Methods: All MLB pitchers who underwent UCLR were identified through publicly available data. A cohort of pitchers who did not undergo UCLR were matched to pitchers with a history of UCLR, based on sex, age, draft year, and draft round. Of those who were no longer pitching in the MLB, the reason for retirement was determined. Reason for retirement and length of career following UCLR (surgical group) and index year (control group) were determined and compared through prior studies via the MLB HITS database, MLB team websites, and publicly available internet-based injury reports. Results: Overall, 153 MLB pitchers who underwent UCLR between 1974 and 2015 are currently retired. Mean ± SD time to retirement was 4.4 ± 4.7 years (range, 0-26 years) after the index year in the control group and 4.4 ± 3.5 years (range, 0-15 years) after surgery in the UCLR group (P = .388). Patients who were status post-UCLR were significantly more likely to be released during the season (34 of 144, 23.6%) than were players who were not status post-UCLR (14 of 144, 9.7%) (P = .002). Shoulder injury as a reason for retirement was more common in the control group than the UCLR group (P = .011). Elbow injury as a reason for retirement was not more common in either group (P = .379). Leg injury as a reason for retirement was more common in the control group (P = .013). Performance as a reason for retirement was more common in the UCLR group than the control group (P < .001). Conclusion: MLB pitchers who have undergone UCLR are no more likely to retire from shoulder or elbow injuries than are those who have not undergone UCLR. MLB career length was similar between pitchers with and without a history of UCLR. PMID:29318169

This study was designed to assess the neuroprotective effect of xenon-induced delayed postconditioning on spinal cord ischaemia-reperfusion injury (IRI) and to determine the time of administration for best neuroprotection in a rat model of spinal cord IRI. Fifty male rats were randomly divided equally into a sham group, control group, and three xenon postconditioning groups (n=10 per group). The control group underwent spinal cord IRI and immediately inhaled 50% nitrogen/50% oxygen for 3 h at the initiation of reperfusion. The three xenon postconditioning groups underwent the same surgical procedure and immediately inhaled 50% xenon/50% oxygen for 3 h at the initiation of reperfusion or 1 and 2 h after reperfusion. The sham operation group underwent the same surgical procedure without aortic occlusion, and inhaled 50% nitrogen/50% oxygen. Neurological function was assessed using the Basso, Beattie, and Bresnahan score at 4, 24, and 48 h of reperfusion. Histological examination was performed using Nissl staining and immunohistochemistry, and apoptosis was detected by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labelling staining. Compared with the control group, the three xenon postconditioning groups showed improvements in neurological outcomes, and had more morphologically normal neurones at 48 h of reperfusion. Apoptotic cell death was reduced and the ratio of Bcl-2/Bax immunoreactivity increased in xenon-treated rats compared with controls. Xenon postconditioning up to 2 h after reperfusion provided protection against spinal cord IRI in rats, but the greatest neuroprotection occurred with administration of xenon for 1 h at reperfusion. © The Author [2013].

To evaluate the effects of intracameral injection of ranibizumab and bevacizumab on the corneal endothelium by scanning electron microscopy (SEM). Twenty-eight female rabbits were randomly divided into four equal groups. Rabbits in groups 1 and 2 underwent intracameral injection of 1 mg/0.1 mL and 0.5 mg/0.05 mL ranibizumab, respectively; group 3 was injected with 1.25 mg/0.05 mL bevacizumab. All three groups were injected with a balanced salt solution (BSS) into the anterior chamber of the left (fellow) eye. None of the rabbits in group 4 underwent an injection. Corneal thickness and intraocular pressure were measured before the injections, on the first day, and in the first month after injection. The rabbits were sacrificed and corneal tissues were excised in the first month after injection. Specular microscopy was used for the corneal endothelial cell count. Endothelial cell density was assessed and comparisons drawn between the groups and the control. Micrographs were recorded for SEM examination. The structure of the corneal endothelial cells, the junctional area of the cell membrane, the distribution of microvillus, and the cell morphology of the eyes that underwent intracameral injection of vascular endothelial growth factor (VEGF), BSS, and the control group were compared. Corneal thickness and intraocular pressure were not significantly different between the groups that underwent anti-VEGF or BSS injection and the control group on the first day and in the first month of injection. The corneal endothelial cell count was significantly diminished in all three groups; predominantly in group 1 and 2 (P<0.05). The SEM examination revealed normal corneal endothelial histology in group 3 and the control group. Eyes in group 1 exhibited indistinctness of corneal endothelial cell borders, microvillus loss in the luminal surface, excessive blebbing, and disintegration of intercellular junctions. In group 2, the cell structure of the corneal endothelium and intercellular junctions were normal. However, a relative reduction was observed in the microvillus density of endothelial cells. Although eyes in group 3 were morphologically similar to fellow eyes and the control group, disarrangement in endothelial cell borders was evident. The SEM examination pointed out deterioration in endothelial cell morphology after intracameral injection of 1 and 0.5 mg ranizumab. However, the effects of intracameral bevacizumab injection on corneal endothelial cells were similar to those found in fellow eyes and the control group. Further large-scale studies that examine the cellular changes by transmission electron microscopy are required to support the results of the present study that evaluates the structural changes in endothelial cells by SEM.

To evaluate the ovarian response cycles of IVF-ET in patients who previously underwent laparoscopic cystectomy for endometriomas. Retrospective study with prospective selection of participants and controls. Instituto de Ginecología y Fertilidad Buenos Aires, Argentina. Thirty-nine patients underwent an operation for ovarian endometriomas by atraumatic removal of the pseudocapsule with minimal bipolar cauterization of small bleeders and an IVF-ET cycle (group A) and 39 control patients of similar age underwent an IVF-ET cycle for tubal factor infertility (group B). Laparoscopic endometrioma cystectomy, IVF-ET cycle. E(2) levels, number of gonadotropin ampoules, follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate. There were no differences in all the parameters studied (E(2) levels, number of follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate) except for the number of gonadotropin ampoules needed for ovarian hyperstimulation, which was significantly higher in group A than in group B. Our results indicate that laparoscopic cystectomy for endometriomas is an appropriate treatment since it did not negatively affect the ovarian response for IVF-ET.

To investigate the effects of a sliding rehabilitation machine on balance and gait in chronic stroke patients. A non-randomized crossover design. Inpatient rehabilitation in a general hospital. Thirty patients with chronic stroke who had medium or high falling risk as determined by the Berg Balance Scale. Participants were divided into two groups and underwent four weeks of training. Group A (n = 15) underwent training with the sliding rehabilitation machine for two weeks with concurrent conventional training, followed by conventional training only for another two weeks. Group B (n = 15) underwent the same training in reverse order. The effect of the experimental period was defined as the sum of changes during training with sliding rehabilitation machine in each group, and the effect of the control period was defined as those during the conventional training only in each group. Functional Ambulation Category, Berg Balance Scale, Six-Minute Walk Test, Timed Up and Go Test, Korean Modified Barthel Index, Modified Ashworth Scale and Manual Muscle Test. Statistically significant improvements were observed in all parameters except Modified Ashworth Scale in the experimental period, but only in Six-Minute Walk Test (P < 0.01) in the control period. There were also statistically significant differences in the degree of change in all parameters in the experimental period as compared to the control period. The sliding rehabilitation machine may be a useful tool for the improvement of balance and gait abilities in chronic stroke patients.

To employ a national database to evaluate the association between intraoperative corticosteroid injection at the time of ankle arthroscopy and postoperative infection rates in Medicare patients. A national insurance database was queried for Medicare patients who underwent ankle arthroscopy, including arthroscopic removal of loose body, synovectomy, and limited or extensive debridement. Two groups were created: ankle arthroscopy with concomitant local steroid injection (n = 459) and a control group of patients who underwent ankle arthroscopy without intraoperative local steroid injection (n = 9,327). The demographics and Charlson Comorbidity Index of each group were compared. Infection rates within 6 months postoperatively were assessed using International Classification of Diseases, 9th revision, and Current Procedural Terminology codes and compared between groups using χ(2)-tests. A total of 9,786 unique patients who underwent ankle arthroscopy were included in the study. There were no statistically significant differences between the steroid injection study group and controls for the assessed infection-related variables, including gender, age group, obesity, smoking, and average Charlson Comorbidity Index. The infection rate for patients who had a local steroid injection at the time of surgery was 3.9% (18/459 patients), compared with 1.8% (168/9,327 patients) in the control group (odds ratio, 2.2; 95% confidence interval, 1.4 to 3.7; P = .002.) The majority of this difference was noted between the 65 and 79 years age groups. The use of intraoperative intraarticular corticosteroid injection at the time of ankle arthroscopy in Medicare patients is associated with significantly increased rates of postoperative infection compared with controls without intraoperative steroid injections.

Background The purpose of this work was to look into the effects of infliximab on wound healing in experimental glaucoma filtration surgery and to compare the antifibrotic effects of this agent to that of mitomycin-C (MMC). Methods Twenty-eight male New Zealand White rabbits were randomly assigned to four groups, each including seven rabbits: control group, sham group, MMC group, and infliximab group. The rabbits in the control group were not operated on and did not receive any treatment. The rabbits in the sham group underwent trabeculectomy and had one drop of saline instilled four times a day for 14 days. The rabbits in the MMC treatment group underwent trabeculectomy, and a sponge soaked in 0.4 mg/mL MMC was applied intraoperatively to the scleral surgical site for three minutes. The rabbits in the infliximab treatment group underwent trabeculectomy and one drop of 10 mg/mL infliximab was instilled four times a day for 14 days after surgery. On day 14 of the experiment, the operated and control eyes were enucleated and histologically and immunohistochemically analyzed. Results The mean fibroblast and mononuclear cell (MNC) numbers and the mean immunostaining intensities of transforming growth factor-β (TGF-β), fibroblast growth factor-β (FGF-β), and platelet-derived growth factor (PDGF) in the sham group were higher than those of the control group (P<0.01). The mean fibroblast and MNC numbers and the mean immunostaining intensities of TGF-β, FGF-β, and PDGF in the MMC and infliximab groups were statistically significantly lower than those of the sham group (P<0.01). The mean fibroblast and MNC numbers and the mean TGF-β, FGF-β, and PDGF immunostaining intensities of the MMC and infliximab groups were similar (P>0.05). Conclusion Our study suggests that topical infliximab effectively suppresses the subconjunctival wound healing response after experimental glaucoma filtration surgery, reducing the MNC and fibroblast numbers and immunostaining intensities of TGF-β, FGF-β, and PDGF.

This study compares internal and external distraction devices in the treatment of midface retrusion. 20 patients were treated with midface distraction (12 Crouzon, 4 Apert, 4 others); 12 with internal distraction (MID device), 8 with external distraction (Red or Blue device). The two groups were compared regarding operation time, peroperative blood loss and complications. The groups were comparable regarding patient age, sex, weight and diagnosis. In the MID-group, 7 of 12 patients (58%) underwent Le Fort III, 5 underwent 12 monobloc (32%). In the Blue device group, three of eight patients underwent Le Fort II (38%), three of eight underwent Le Fort III (38%), and two of eight underwent monobloc (25%). Operation time was shorter in the Blue device (mean 298 min) than in the MID group (mean 354 min). Peroperative blood loss and complication rates were similar. The internal distraction device is the 'gold standard' for treating midface retrusion. The use of an external distraction device in midface distraction osteogenesis is associated with a shorter operation time; peroperative blood loss and complications were similar. An external device affords better 3-dimensional control during the distraction process, so external distraction is preferable in patients who will tolerate this treatment.

Cross-linked hyaluronic acid (HA) gel is widely used in esthetic medicine. Late bacterial infection (LBI) is a rare, but severe complication after HA augmentation. The aim of this study was to determine whether patients who underwent the HA injection procedure and developed LBI had qualitatively different bacterial flora on the skin compared to patients who underwent the procedure without any complications. The study group comprised 10 previously healthy women with recently diagnosed, untreated LBI after HA augmentation. The control group comprised 17 healthy women who had a similar amount of HA injected with no complications. To assess the difference between the two groups, their skin flora was cultured from nasal swabs, both before and after antibiotic treatment in the study group. A significant increase in the incidence of Staphylococcus epidermidis was detected in the control group ( P =0.000) compared to the study group. The study group showed a significantly higher incidence of Staphylococcus aureus ( P =0.005), Klebsiella pneumoniae ( P =0.006), Klebsiella oxytoca ( P =0.048), and Staphylococcus haemolyticus ( P =0.048) compared to the control group. The bacterial flora on the skin differed in patients with LBI from the control group. The control group's bacterial skin flora was dominated by S. epidermidis . Patients with LBI had a bacterial skin flora dominated by potentially pathogenic bacteria.

Because definitive long-term results are not yet available, the oncological safety of laparoscopic surgery for treatment of rectal cancer remains unproven. The aim of this prospective non-randomised study was to assess the feasibility and short-term outcome of laparoscopic total mesorectal excision (LTME) after 25--30 Gy preoperative radiotherapy and to compare the results with a matched-control group of open TME (OTME). A series of 41 patients with primary rectal cancer underwent LTME for rectal cancer and were matched with a historical control group of 41 patients who underwent OTME. Both groups received preoperative short-term radiotherapy. There was no mortality in the LTME group and 2% mortality in the OTME group. The overall postoperative morbidity was 37% in the LTME group and 51% in the OTME group, including an anastomotic leakage of 9 and 14% in the LTME and OTME groups respectively. A positive circumferential margin was found in 7% of patients in the LTME group and in 12% of the patients in the OTME group. This study shows that LTME is technically feasible and can be performed safely. We show at least a similar surgical completeness using a laparoscopic technique compared with open surgery.

This multicenter, randomized controlled study evaluates the safety of early oral feeding following gastrectomy, and its effect on the length of postoperative hospital stay. The subjects of this study were patients who underwent distal gastrectomy (DG) or total gastrectomy (TG) for gastric cancer between January 2014 and December 2015. Patients were randomly assigned to the early oral feeding group (intervention group) or the conventional postoperative management group (control group) for each procedure. We evaluated the length of postoperative hospital stay and the incidence of postoperative complications in each group. No significant differences in length of postoperative stay were found between the intervention and control groups of the patients who underwent DG. The incidence of postoperative complications was significantly greater in the DG intervention group. In contrast, the length of postoperative stay was significantly shorter in the TG intervention group, although the TG group did not attain the established target sample size. Early oral feeding did not shorten the postoperative hospital stay after DG. The higher incidence of postoperative complications precluded the unselected adoption of early oral feeding for DG patients. Further confirmative studies are required to definitively establish the potential benefits of early oral feeding for TG patients.

Enhanced recovery after surgery (ERAS) protocols provide recommendations for care in various surgical fields. However, there is scarce information on the application of these protocols in tuberculous empyema surgery. The purpose of this research is to evaluate the outcomes of ERAS recommendations for patients who received tuberculous empyema surgery. A retrospective analysis was performed on patients who underwent tuberculous empyema surgery in our hospital from March 2011 to March 2016. The patients were divided into an ERAS group and a conventional control group. The main outcome measure was the postoperative median length of stay (including readmissions). Principles related to ERAS were documented, and the postoperative median hospital stay was analyzed statistically between the two groups. A total of 92 patients underwent 93 consecutive tuberculous empyema surgical treatments. The postoperative fasting time, chest tube duration, and length of stay were shorter in the ERAS group compared with the control group. The volume of chest tube drainage in the ERAS group was significantly smaller than that of the control group. No statistical differences were observed in the postoperative complications and reasons for readmission between the two groups. Application of ERAS recommendations in patients receiving tuberculous empyema operations decreased the length of stay and chest tube drainage compared to the control group.

The aim of this study was to determine whether molar incisor hypomineralization (MIH) is greater in patients with cleft lip and palate (CLP) who underwent primary alveolar grafting (PAG) as compared with CLP waiting for secondary alveolar grafting (SAG) and with controls. A retrospective analysis of intraoral photographs of 13 CLP patients who underwent a PAG, 28 CLP prior to SAG, and 60 controls without CLP was performed. Mantel-Haenszel χ tests were used to compare the 3 groups for differences in MIH scores, and Wilcoxon rank sum tests were used to compare the groups for differences in average MIH scores. A 5% significance level was used for all tests. Molar incisor hypomineralization scores were significantly higher for the PAG and SAG groups compared with the control group (P < 0.001). The PAG group had significantly higher incisor MIH (P = 0.016) compared with the SAG group. Molar incisor hypomineralization average scores were significantly higher for the 2 graft groups compared with the controls (P < 0.0001). The PAG group had significantly higher average MIH score and average MIH score for incisors compared with the SAG group (P = 0.03). Cleft lip and palate patients have significantly greater MIH compared with controls, and CLP patients with PAGs have significantly greater MIH in the incisor region compared with CLP patients with SAGs, indicating that subjects with PAGs have more severely affected dentition.

To investigate the effect of mirror therapy on the gait of patients with subacute stroke. Randomized controlled experimental study. Outpatient rehabilitation hospital. Thirty-four patients with stroke were randomly assigned to two groups: a mirror therapy group (experimental) and a control group. The stroke patients in the experimental group underwent comprehensive rehabilitation therapy and mirror therapy for the lower limbs. The stroke patients in the control group underwent sham therapy and comprehensive rehabilitation therapy. Participants in both groups received therapy five days per week for four weeks. Temporospatial gait characteristics, such as single stance, stance phase, step length, stride, swing phase, velocity, and cadence, were assessed before and after the four weeks therapy period. A significant difference was observed in post-training gains for the single stance (10.32 SD 4.14 vs. 6.54 SD 3.23), step length (8.47 SD 4.12 vs. 4.83 SD 2.14), and stride length (17.03 SD 6.57 vs 10.54 SD 4.34) between the experimental group and the control group (p < 0.05). However, there were no significant differences between two groups on stance phase, swing phase, velocity, cadence, and step width (P > 0.05). We conclude that mirror therapy may be beneficial in improving the effects of stroke on gait ability. © The Author(s) 2014.

To employ a national database of Medicare patients to evaluate the association of ipsilateral intra-articular knee corticosteroid injections at the time of knee arthroscopy with the incidence of postoperative infection. A national Medicare insurance database was queried for patients who underwent ipsilateral intra-articular corticosteroid injection of the knee at the time of knee arthroscopy from 2005 to 2012. Patients who underwent arthroscopically assisted open procedures, those who underwent more complex arthroscopic procedures, and those for whom laterality were not coded were excluded. This study group was compared to a control cohort of patients without intraoperative steroid injections that was matched to the study group for age, gender, obesity, diabetes mellitus, and smoking status. Infection rates within 3 and 6 months postoperatively were assessed using International Classification of Diseases, 9th Revision, and Current Procedural Terminology codes. The incidence of postoperative infection rates after knee arthroscopy was significantly higher at 3 months (0.66%; odds ratio [OR], 2.6; P < .0001) and 6 months (1.92%; OR, 3.6; P < .0001) in patients who underwent ipsilateral intra-articular knee steroid injection at the time of knee arthroscopy (n = 2,866) compared with matched controls without intraoperative injections (n = 170,350) at 3 months (0.25%) and 6 months (0.54%). The present study demonstrates a significant increase in postoperative infection in Medicare patients who underwent ipsilateral intra-articular knee corticosteroid injections at the time of knee arthroscopy compared with a matched control group without intraoperative injection.

To evaluate lenticular oxidative stress in rat menopausal models. Forty Wistar female albino rats were included in this study. A total of thirty rats underwent oophorectomy to generate a menopausal model. Ten rats that did not undergo oophorectomy formed the control group (Group 1). From the rats that underwent oophorectomy, 10 formed the menopause control group (Group 2), 10 were administered a daily injection of methylprednisolone until the end of the study (Group 3), and the remaining 10 rats were administered intraperitoneal streptozocin to induce diabetes mellitus (Group 4). Total oxidant status (TOS), total antioxidant capacity (TAC), and oxidative stress index (OSI) measurements of the crystalline lenses were analyzed. The mean OSI was the lowest in group 1 and highest in group 4. Nevertheless, the difference between the groups was not statistically significant in terms of OSI (p >0.05). The mean TOS values were similar between the groups (p >0.05), whereas the mean TAC of group 1 was significantly higher than that of the other groups (p <0.001). Our results indicate that menopause may not promote cataract formation.

2013-01-01

Background Rotator cuff tears are common injuries that are often treated with surgical repair. Because of the high concentration of growth factors within platelets, platelet-rich plasma (PRP) has the potential to enhance healing in rotator cuff repairs. Hypothesis Platelet-rich plasma would alter the biomechanical and histologic properties of rotator cuff repair during an acute injury response. Study Design Controlled laboratory study. Methods Platelet-rich plasma was produced from inbred donor rats. A tendon-from-bone supraspinatus tear was created surgically and an immediate transosseous repair performed. The control group underwent repair only. The PRP group underwent a repair with PRP augmentation. Rats in each group were sacrificed at 7, 14, and 21 days. The surgically repaired tendons underwent biomechanical testing, including failure load, stiffness, failure strain, and stress relaxation characteristics. Histological analysis evaluated the cellular characteristics of the repair tissue. Results At 7- and 21-day periods, augmentation with PRP showed statistically significant effects on the biomechanical properties of the repaired rat supraspinatus tear, but failure load was not increased at the 7-, 14-, or 21-day periods (P = .688, .209, and .477, respectively). The control group had significantly higher stiffness at 21 days (P = .006). The control group had higher failure strain at 7 days (P = .02), whereas the PRP group had higher failure strain at 21 days (P = .008). Histologically, the PRP group showed increased fibroblastic response and vascular proliferation at each time point. At 21 days, the collagen fibers in the PRP group were oriented in a more linear fashion toward the tendon footprint. Conclusion In this controlled, rat model study, PRP altered the tissue properties of the supraspinatus tendon without affecting the construct’s failure load. Clinical Relevance The decreased tendon tissue stiffness acutely and failure to enhance tendon-to-bone healing of repairs should be considered before augmenting rotator cuff repairs with PRP. Further studies will be necessary to determine the role of PRP in clinical practice. PMID:22822177

The aim of the study was to analyze the treatment effect of transumbilical single-port laparoscopic varicocelectomy (TUSPLV) on recurrent varicocele (VC). In order to compare the surgical effects of TUSPLV to traditional retroperitoneal ligation of the internal spermatic vein, 64 patients with recurrent VC were enrolled and divided into the control group (n=30) and the observation group (n=34). Patients in the control group underwent surgery using traditional retroperitoneal ligation of the internal spermatic vein, while those in the observation group underwent surgery using TUSPLV. The results showed that the time of operation and bleeding volume in the observation group were significantly lower. The occurrence and recurrence rates of periprocedural complications were considerably lower in the observation group. Differences were statistically significant (P<0.05). In terms of the pregnancy rate, the difference between the 2 groups had no statistical significance (P>0.05). We concluded that employing TUSPLV to treat recurrent VC was safe and effective.

To determine if dexamethasone could be a suitable option in the treatment of patients with unexplained infertility. This study was carried out in the Obstetrics Department of Amir University Hospital, Semnan, Iran, from April 2001 to May 2008. One hundred and twenty-four cases of unexplained infertility that underwent ovulation induction and intrauterine insemination (IUI) (only one cycle) were evaluated, and divided into 2 groups. Sixteen cases were excluded, as they were unresponsive to the induction ovulation regimen. Group I (n=42) received clomiphene citrate (CC) + dexamethasone, and the control group (group II, n=66) received CC alone. These groups were the same in age, duration of infertility, and body mass index. The clinical pregnancy rates were evaluated in 2 groups by using statistical tests. The clinical pregnancy rate was 21.4% in group I, and 4.5% in group II. There was a significant statistical difference between the groups (relative risk=4.71, 95% confidence interval=1.35-16.42, p=0.0085). The pregnancy rate in women with unexplained infertility that underwent ovulation induction with CC + dexamethasone + IUI was significantly higher than those who underwent ovulation induction with CC alone + IUI.

Background and aims: Barrett’s esophagus (BE) and colorectal neoplasms share similar risk factors. Previous studies have shown variable prevalence of colon polyps in patients with BE. Our aims were to determine the prevalence and incidence of colon polyps in patients with BE, compared to those without BE. Methods: In this case-control study, the study group included patients, aged 50–75 years, with biopsy-proven BE, who underwent colonoscopy at Cleveland Clinic from January 2002 to December 2011. The control group consisted of age- and sex-matched patients who underwent colonoscopy and also an endoscopy with no evidence of BE during the same time period. Exclusion criteria for both groups were family- or personal previous history of colon cancer or polyps, prior colonic resection, inflammatory bowel disease and familial polyposis syndromes. Patient demographics, comorbidities, medication use and endoscopic and colonoscopic details were collected, including biopsy results. Results: A total of 519 patients were included in the study; 173 patients with BE in the study group and 346 without BE in the control group. Mean age at index colonoscopy was 61 ± 8 years and 75% of patients were male. On index colonoscopy, patients with BE were more likely to have polyps than controls (45% vs 32%, respectively; P = 0.003). Patients underwent between one and five colonoscopies during the follow-up. On multivariate analysis—after adjusting for age, gender and diabetes—patients with BE were 80% more likely to have any type of polyp, and 50% more likely to have adenomas found during colonoscopy. Conclusions: Patients with BE had higher prevalence and incidence of colon polyps. This has important clinical implications for screening and surveillance in BE patients. PMID:25085954

Marginal ulceration at the gastrojejunostomy is a serious complication after laparoscopic Roux-en-Y gastric bypass surgery (LRYGB) and occurs in 1%-16% of patients. Proton pump inhibitors (PPIs) might lower the occurrence of these ulcers. The aim of the present study was to evaluate the effect of 6 months prophylactic usage of PPIs on the development of marginal ulceration and compare this with a historic patient control group. A single institution cohort at a bariatric center of excellence, The Sint Lucas Andreas Zienkenhuis, Amsterdam A consecutive database of patients who underwent LRYGB from November 2007 to September 2012 in a single institution was retrospectively reviewed. From August 2011, patients received a standard dose of pantozol 40 mg once daily directly postoperatively for 6 months. No standard PPI prophylaxis was administered before August 2011, and the patients not using PPIs in this historic cohort served as the control group. A total of 610 patients underwent LRYGB, of which 128 patients (21.0%) underwent revisional surgery. Postoperative PPIs were administered in the intervention group of 337 patients, compared with the historic control group consisting of 273 patients. Six patients (1.2%) who received postoperative PPIs versus 20 patients (7.3 %) in the historic control group developed marginal ulceration (P = .001). Patients using proton pump inhibitors developed fewer gastrointestinal complaints postoperatively (P< .001). Routine usage of PPIs reduced the occurrence of marginal ulceration after LRYGB.

[Purpose] We aimed to examine the effectiveness of a community-based virtual reality treadmill training (CVRTT) program on static balance abilities in patients with stroke. [Subjects and Methods] Patients (n = 20) who suffered a stroke at least 6 months prior to the study were recruited. All subjects underwent conventional physical therapy for 60 min/day, 5 days/week, for 4 weeks. Additionally, the CVRTT group underwent community-based virtual reality scene exposure combined with treadmill training for 30 min/day, 3 days/week, for 4 weeks, whereas the control group underwent conventional physical therapy, including muscle strengthening, balance training, and indoor and outdoor gait training, for 30 min/day, 3 days/week, for 4 weeks. Outcome measurements included the anteroposterior, mediolateral, and total postural sway path lengths and speed, which were recorded using the Balancia Software on a Wii Fit(™) balance board. [Results] The postural sway speed and anteroposterior and total postural sway path lengths were significantly decreased in the CVRTT group. Overall, the CVRTT group showed significantly greater improvement than the control group. [Conclusions] The present study results can be used to support the use of CVRTT for effectively improving balance in stroke patients. Moreover, we determined that a CVRTT program for stroke patients is both feasible and suitable.

To investigate whether laparoscopic excision of ovarian endometriomas pretreated with operation by gynecologists or reproductive surgeons exerts different effects on in vitro fertilization-intracytoplasmic sperm injection results. Retrospective case control study. Relevant information was collected from the electronic records of women who underwent IVF/ICSI from 01/01/2013 to 30/12/2015 in our unit. The study group consisted of 35 women who previously had laparoscopic endometrioma excision by reproductive surgeons in our unit; the control group included 36 patients who underwent surgery for endometriomas by gynecologists in our hospital. There were slightly higher numbers of AFC and higher pregnancy rate in the study group, although differences did not reach statistical significance. For patients over 35 years old, there were more oocyte retrieved, mature oocytes and two pronucei (2PN) in the study group than the control group although observed differences did not reach statistical significance. Electrocautery is more deleterious on ovarian reserve than hemostatic suture. In procedure of patients who wish to conceive, surgeons should use hemostatic suturing technique preferentially.

Purpose and design The aim of this study was to establish the prevalence of known glaucoma in patients undergoing ectropion or entropion surgical repair. In this study, retrospective review of case series was performed. Participants All patients who underwent ectropion or entropion surgery in a tertiary medical center between 2007 and 2014 were included. The etiology of eyelid malpositioning was involutional or cicatricial. Methods The medical files of the study participants were reviewed for the presence and type of glaucoma, medical treatment, duration of treatment, and the amount of drops per day. These data were compared to a matched control group of 101 patients who underwent blepharoplasty for dermatochalasis in the same department during the same period. Main outcome measure In this study, the prevalence of glaucoma in individuals with ectropion or entropion was the main outcome measure. Results A total of 227 patients (57% men, mean age: 79.2 years) who underwent ectropion or entropion surgery comprised the study group and 101 patients who underwent upper blepharoplasty for dermatochalasis comprised the control group. Compared to four patients in the control group (4%, P=0.01), 30 of the study patients (13.2%) had coexisting glaucoma. Of 30 glaucomatous patients, 25 had primary open-angle glaucoma for a mean duration of 10.3 years. The glaucomatous patients were treated with an average of 2.7 antiglaucoma medications. Conclusion An increased prevalence of known glaucoma in patients undergoing ectropion or entropion repair surgery was found. This observation may indicate that the chronic usage of topical anti-glaucoma eyedrops may lead to an increased risk of developing eyelid malpositions, especially in elderly patients. PMID:27785003

Due to the importance of pain control after abdominal surgery, several methods such as transversus abdominis plane (TAP) block are used to reduce the pain after surgery. TAP blocks can be performed using various ultrasound-guided approaches. Two important approaches to do this are ultrasound-guided lateral and posterior approaches. This study aimed to compare the two approaches of ultrasound-guided lateral and posterior TAP blocks to control pain after cesarean section. In this double-blind clinical trial study, 76 patients scheduled for elective cesarean section were selected and randomly divided into two groups of 38 and underwent spinal anesthesia. For pain management after the surgery, one group underwent lateral TAP block and the other group underwent posterior TAP block using 20cc of ropivacaine 0.2% on both sides. Pain intensity was evaluated based on Numerical Analog Scale (NAS) at rest and when coughing, 2, 4, 6, 12, 24 and 36 hours after surgery. The pain at rest in the posterior group at all hours post surgery was lower than the lateral group, especially at 6, 12 and 24 hours after the surgery and the difference was statistically significant ( p =0.03, p <0.004, p =0.001). The results of this study show that ultrasound-guided posterior TAP block compared with the lateral TAP block was more effective in pain control after cesarean section.

To investigate the influence of uterine artery embolization (UAE) on fertility after bilateral UAE with either tris-acryl gelatin microspheres (TAGM) or gelatin particles (GP). Six ewes that underwent UAE with TAGM, 6 ewes that underwent UAE with GP, and 6 control ewes were compared. After hormonal synchronization of the menstrual cycle, artificial insemination (AI) was performed. When pregnancy did not result, ewes were naturally inseminated. After AI, progesterone concentrations in blood increased and were maintained at >1.0 ng/mL in 9 ewes (3 per group). Three ewes became pregnant after AI. The abortion rate was higher in the UAE group. The remaining 15 sheep were naturally inseminated, with 14 delivering 15 lambs. Mean period of term gestation in UAE group ewes was 155.7 versus 158.6 days in control group ewes. Lambs' body weight, body length, and withers height after birth did not differ between those from UAE group and control group. Lambs from ewes embolized with GP tended to be smaller and had lower body weight than those from other groups. Uterine artery embolization influenced reproductive ability in sheep and UAE with GP could lead to intrauterine growth retardation.

To compare the surgical proficiency of medical students who underwent traditional training or virtual reality training for argon laser trabeculoplasty with the PixEye simulator. The cohort comprised of 47 fifth year male medical students from the College of Medicine, King Faisal University, Saudi Arabia. The cohort was divided into two groups: students (n = 24), who received virtual reality training (VR Group) and students (n = 23), who underwent traditional training (Control Group). After training, the students performed the trabeculoplasty procedure. All trainings were included concurrent power point presentations describing the details of the procedure. Evaluation of surgical performance was based on the following variables: missing the exact location with the laser, overtreatment, undertreatment and inadvertent laser shots to iris and cornea. The target was missed by 8% of the VR Group compared to 55% in the Control Group. Overtreatment and undertreatment was observed in 7% of the VR Group compared to 46% of the Control Group. Inadvertent laser application to the cornea or iris was performed by 4.5% of the VR Group compared to 34% of the Control Group. Virtual reality training on PixEye simulator may enhance the proficiency of medical students and limit possible surgical errors during laser trabeculoplasty.

Sepsis is a potentially lethal condition, and it is associated with platelet alterations. The present study sought to investigate the activity of ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase), E-5'-nucleotidase, and ecto-adenosine deaminase (E-ADA) in the platelets of rats that were induced with sepsis. Male Wistar rats were divided into three groups of ten animals each: a negative control group (normal; NC); a group that underwent surgical procedures (sham); and a group that underwent cecal ligation and perforation (CLP). The induction of sepsis was confirmed by bacteremia, and the causative pathogen identified was Escherichia coli. Hematological parameters showed leukocytosis and thrombocytopenia in animals in the septic group. The results also revealed that there were significant (p < 0.05) increases in adenosine triphosphate (ATP) and adenosine monophosphate (AMP) hydrolyses, and in the deamination of adenosine in the CLP group compared to the sham and control groups. Conversely, ADP hydrolysis was significantly decreased (p < 0.05) in the CLP group compared to the sham and control groups. Purine levels were analyzed by high-performance liquid chromatography (HPLC) in serum samples from control, sham, and CLP groups. Increased concentrations of ATP, adenosine, and inosine were found in the CLP group compared to the sham and control groups. Conversely, the concentrations of ADP and AMP in the CPL group were not significantly altered. We suggest that alterations in hematological parameters, nucleotide hydrolysis in platelets, and nucleotide concentrations in serum samples of rats with induced sepsis may be related to thromboembolic events.

Among patients undergoing mitral-valve surgery, 30 to 50% present with atrial fibrillation, which is associated with reduced survival and increased risk of stroke. Surgical ablation of atrial fibrillation has been widely adopted, but evidence regarding its safety and effectiveness is limited. We randomly assigned 260 patients with persistent or long-standing persistent atrial fibrillation who required mitral-valve surgery to undergo either surgical ablation (ablation group) or no ablation (control group) during the mitral-valve operation. Patients in the ablation group underwent further randomization to pulmonary-vein isolation or a biatrial maze procedure. All patients underwent closure of the left atrial appendage. The primary end point was freedom from atrial fibrillation at both 6 months and 12 months (as assessed by means of 3-day Holter monitoring). More patients in the ablation group than in the control group were free from atrial fibrillation at both 6 and 12 months (63.2% vs. 29.4%, P<0.001). There was no significant difference in the rate of freedom from atrial fibrillation between patients who underwent pulmonary-vein isolation and those who underwent the biatrial maze procedure (61.0% and 66.0%, respectively; P=0.60). One-year mortality was 6.8% in the ablation group and 8.7% in the control group (hazard ratio with ablation, 0.76; 95% confidence interval, 0.32 to 1.84; P=0.55). Ablation was associated with more implantations of a permanent pacemaker than was no ablation (21.5 vs. 8.1 per 100 patient-years, P=0.01). There were no significant between-group differences in major cardiac or cerebrovascular adverse events, overall serious adverse events, or hospital readmissions. The addition of atrial fibrillation ablation to mitral-valve surgery significantly increased the rate of freedom from atrial fibrillation at 1 year among patients with persistent or long-standing persistent atrial fibrillation, but the risk of implantation of a permanent pacemaker was also increased.

Assessment of virtual reality (VR) distraction for alleviating pain and anxiety during flexible cystoscopy. Cystoscopy is a common ambulatory procedure performed in Urology and can be associated with moderate pain and anxiety. Sophisticated distraction techniques are not used with cystoscopy and VR has not been studied for this procedure. We designed a prospective, randomized, controlled trial assessing the efficacy of VR for alleviating pain and anxiety during flexible cystoscopy. Adult men referred for cystoscopy were randomized into a control or VR group. Subjects were given preprocedure and postprocedure questionnaires addressing anxiety, pain, and time spent thinking about pain. Vitals signs and galvanic skin monitors were used as objective measures. The control group underwent routine cystoscopy and the VR group underwent cystoscopy with VR. Physicians answered a postprocedure questionnaire assessing the difficulty of the exam. All questionnaires used a visual analog score for assessment. 23 patients enrolled in the control group and 22 in the VR group. Mean scores and Student's t-test were employed to analyze the data. No data endpoints showed a statistically significant difference between the 2 groups. We concluded no benefit to VR distraction mitigating pain in male patients during cystoscopy.

Navigated transcranial magnetic stimulation (nTMS) enables preoperative mapping of the motor cortex (M1). The combination of nTMS with diffusion tensor imaging fiber tracking (DTI-FT) of the corticospinal tract (CST) has been described; however, its impact on surgery of motor-eloquent lesions has not been addressed. To analyze the impact of nTMS-based mapping on surgery of motor-eloquent lesions. In this retrospective case-control study, we reviewed the data of patients operated for suspected motor-eloquent lesions between 2012 and 2015. The patients underwent nTMS mapping of M1 and, from 2014, nTMS-based DTI-FT of the CST. The impact on the preoperative risk/benefit analysis, surgical strategy, craniotomy size, extent of resection (EOR), and outcome were compared with a control group. We included 35 patients who underwent nTMS mapping of M1 (group A), 35 patients who also underwent nTMS-based DTI-FT of the CST (group B), and a control group composed of 35 patients treated without nTMS (group C). The patients in groups A and B received smaller craniotomies (P = .01; P = .001), had less postoperative seizures (P = .02), and a better postoperative motor performance (P = .04) and Karnofsky Performance Status (P = .009) than the controls. Group B exhibited an improved risk/benefit analysis (P = .006), an increased EOR of nTMS-negative lesions in absence of preoperative motor deficits (P = .01), and less motor and Karnofsky Performance Status worsening in case of preoperative motor deficits (P = .02, P = .03) than group A. nTMS-based mapping enables a tailored surgical approach for motor-eloquent lesions. It may improve the risk/benefit analysis, EOR and outcome, particularly when nTMS-based DTI-FT is performed. Copyright © 2017 by the Congress of Neurological Surgeons

To evaluate the effectiveness of a low-level laser therapy for pain relief in the perineum following episiotomy during childbirth. Laser irradiation is a painless and non-invasive therapy for perineal pain treatment and its effects have been investigated in several studies, with no clear conclusion on its effectiveness. A double-blind randomised controlled clinical trial. One hundred and fourteen women who underwent right mediolateral episiotomies during vaginal birth in an in-hospital birthing centre in São Paulo, Brazil and reported pain ≥ 3 on a numeric scale (0-10) were randomised into three groups of 38 women each: two experimental groups (treated with red and infrared laser) and a control group. The experimental groups were treated with laser applied at three points directly on the episiotomy after suturing in a single session between 6-56 hours postpartum. We used a diode laser with wavelengths of 660 nm (red laser) and 780 nm (infrared laser). The control group participants underwent all laser procedures, excluding the emission of irradiation. The participants and the pain scores evaluator were blinded to the type of intervention. The perineal pain scores were assessed at three time points: before, immediately after and 30 minutes after low-level laser therapy. The comparison of perineal pain between the three groups showed no significant differences in the three evaluations (p = 0.445), indicating that the results obtained in the groups treated with low-level laser therapy were equivalent to the control group. Low-level laser therapy did not decrease the intensity of perineal pain reported by women who underwent right mediolateral episiotomy. The effect of laser in perineal pain relief was not demonstrated in this study. The dosage may not have been sufficient to provide relief from perineal pain after episiotomy during a vaginal birth. © 2012 Blackwell Publishing Ltd.

To evaluate the effect of adjunctive subtenon injection of triamcinolone acetonide (TA) in gas-filled eyes after vitrectomy for complicated proliferative diabetic retinopathy (PDR). This nonrandomized comparative study included 27 patients (27 eyes) who underwent pars plana vitrectomy and gas tamponade for treatment of PDR with tractional or combined tractional-rhegmatogenous retinal detachment and who received subtenon injection of TA (40 mg) at the end of surgery. The study group was compared with the control group (29 eyes), which was matched with the study group for preoperative and intraoperative parameters, but underwent pars plana vitrectomy and gas tamponade without a subtenon injection of TA. Retinal reattachments without reoperation were achieved in 25 eyes (92.6%) and 26 eyes (89.7%) at 6 months (p = 1.000) in the study and control groups, respectively. The study group and the control group did not differ significantly in the frequency of postoperative proliferative vitreoretinopathy, retinal redetachment rate, reoperation rate, macular pucker formation, postoperative vitreous hemorrhage, gain in visual acuity, intraocular pressure, and intraocular inflammation (p > 0.05). The clinical results of pars plana vitrectomy for complicated PDR are not improved significantly by an adjunctive subtenon TA injection in gas-filled eyes.

The purpose of the current study was to design and evaluate the effectiveness of virtual reality training in improving recovery reactions and reducing fall frequency in older adults. Twenty-four older adults were recruited and randomly assigned to two groups (virtual reality training and control). Both groups underwent three sessions including baseline slip, training and transfer of training on slippery surface. Both groups experienced two slips, one during baseline and the other during the transfer of training trial. The training group underwent 12 simulated slips using a visual perturbation induced by tilting a virtual reality scene while walking on the treadmill and the control group performed normal walking during the training session. Kinematic and kinetic data were collected during all the sessions. Results demonstrated a reduced incidence of falls in the training group during the transfer of training trial as compared to the control group. The training group was able to transfer reactive control strategies learned during training to the second slip trial. The reactive adjustments included reduced slip distance. Additionally, gait parameters reflective of gait instability (stride length, step width, variability in stride velocity) reduced after walking in the VR environment for 15-20 min. The results indicated a beneficial effect of the virtual reality training in reducing slip severity and recovery kinematics in healthy older adults.

Although hydrotherapy is one of the physical therapies adopted to optimize gait rehabilitation in people with Parkinson disease, the quantitative measurement of gait-related outcomes has not been provided yet. This work aims to document the gait improvements in a group of parkinsonians after a hydrotherapy program through 2D and 3D underwater and on land gait analysis. Thirty-four parkinsonians and twenty-two controls were enrolled, divided into two different cohorts. In the first one, 2 groups of patients underwent underwater or land based walking training; controls underwent underwater walking training. Hence pre-treatment 2D underwater and on land gait analysis were performed, together with post-treatment on land gait analysis. Considering that current literature documented a reduced movement amplitude in parkinsonians across all lower limb joints in all movement planes, 3D underwater and on land gait analysis were performed on a second cohort of subjects (10 parkinsonians and 10 controls) who underwent underwater gait training. Baseline land 2D and 3D gait analysis in parkinsonians showed shorter stride length and slower speed than controls, in agreement with previous findings. Comparison between underwater and on land gait analysis showed reduction in stride length, cadence and speed on both parkinsonians and controls. Although patients who underwent underwater treatment exhibited significant changes on spatiotemporal parameters and sagittal plane lower limb kinematics, 3D gait analysis documented a significant (p<0.05) improvement in all movement planes. These data deserve attention for research directions promoting the optimal recovery and maintenance of walking ability. Crown Copyright © 2016. Published by Elsevier B.V. All rights reserved.

Objective Fertility sparing surgery (FSS) is a strategy often considered in young patients with early epithelial ovarian cancer. We investigated the role and the outcomes of FSS in eEOC patients who underwent comprehensive surgery. Methods From January 2003 to January 2011, 24 patients underwent fertility sparing surgery. Eighteen were one-to-one matched and balanced for stage, histologic type and grading with a group of patients who underwent radical comprehensive staging (n=18). Demographics, surgical procedures, morbidities, pathologic findings, recurrence-rate, pregnancy-rate and correlations with disease-free survival were assessed. Results A total of 36 patients had a complete surgical staging including lymphadenectomy and were therefore analyzed. Seven patients experienced a recurrence: four (22%) in the fertility sparing surgery group and three (16%) in the control group (p=not significant). Sites of recurrence were: residual ovary (two), abdominal wall and peritoneal carcinomatosis in the fertility sparing surgery group; pelvic (two) and abdominal wall in the control group. Recurrences in the fertility sparing surgery group appeared earlier (mean, 10.3 months) than in radical comprehensive staging group (mean, 53.3 months) p<0.001. Disease-free survival were comparable between the two groups (p=0.422). No deaths were reported. All the patients in fertility sparing surgery group recovered a regular period. Thirteen out of 18 (72.2%) attempted to have a pregnancy. Five (38%) achieved a spontaneous pregnancy with a full term delivery. Conclusion Fertility sparing surgery in early epithelial ovarian cancer submitted to a comprehensive surgical staging could be considered safe with oncological results comparable to radical surgery group.

To evaluate the effectiveness of routine rapid insertion of a Bakri balloon during cesarean section for placenta previa based on a retrospective control study. Women with singleton pregnancies who underwent cesarean section for placenta previa at our institution between 2003 and 2016 were enrolled. Between 2015 and 2016, women who routinely underwent balloon tamponade during cesarean section were defined as the balloon group. Between 2003 and 2014, women who underwent no hemostatic procedures except balloon tamponade were defined as the non-balloon group. The clinical outcomes of the two groups were retrospectively analyzed. Of the 266 women with placenta previa, 50 were in the balloon group and 216 were in the non-balloon group. The bleeding amounts were significantly smaller in the balloon group than in the non-balloon group: intraoperative bleeding (991 vs. 1250 g, p < 0.01), postoperative bleeding (62 vs. 150 g, p < 0.01), and total bleeding (1066 vs. 1451 g, p < 0.01). Furthermore, the mean surgical duration was shorter in the balloon group than the non-balloon group (30 vs. 50 min, p < 0.01). In the balloon group, five patients suffered from increasing hemorrhage due to prolapse of the balloon from the uterus after the operation, but the hemorrhage was controlled by balloon re-insertion without additional hemostatic procedures. This study demonstrated that the routine rapid insertion of Bakri balloon tamponade during cesarean section significantly decreased intra- and postoperative hemorrhage and shortened the surgical duration in women with placenta previa.

Boxing training including traditional stretching, muscular strength training, and duration training would be considered to be effective for improved functional stretching, dynamic balance, walking speed, and quality of life. We aimed to investigate upper limb function, balance, gait, and quality of life in stroke patients before and after a sitting boxing program. Twenty-six participants were randomly allocated to a boxing group (n = 13) and control group (n = 13) after the upper limb function, balance, gait, and quality of Life were recorded. The boxing group underwent a sitting boxing program (3 times/week) as well as conventional physical therapy (3 times/week) for 6 weeks. The control group only underwent conventional physical therapy (3 times/week) for 6 weeks. The Manual Functional Test (MFT), non-affected hand grip, Berg Balance Scale (BBS), velocity moment with eye opened, 10-m Walk Test (10 MWT), and Stroke-Specific Quality of Life questionnaire (SS-QOL) were significantly improved in the boxing group (p < 0.05) and showed significantly greater improvements in the boxing group compared to the control group (p < 0.05) after 6 weeks. The sitting boxing program group had positive effects on upper extremity function, balance, gait, and quality of life in stroke patients.

To perform a meta-analysis on the precision and safety of femtosecond laser-assisted anterior capsulotomy versus conventional manual continuous curvilinear capsulorrhexis. This meta-analysis was conducted from February 2010 to November 2014. Literature search on PubMed, Google Scholar, ExcerptaMedica database and Cochrane Library was done to identify randomised controlled trials and case-control studies. SPSS 20 was used for data analysis. Of the 10 articles included, there were 3(30%) randomised controlled trials and 7(70%) non-randomised controlled trials. The meta-analysis was based on a total of 2,882eyes. Of them, 1,498(51.97%) underwent femtosecond laser-assisted capsulotomy and 1,384(48.02%) underwent manual continuous curvilinear capsulorrhexis. The diameter of the capsulotomy and the rates of anterior capsule tear showed no statistical difference between the femtosecond laser group and the manual capsulorrhexis group (p=0.29 and p=0.68). In terms of circularity of capsulotomy, femtosecond laser group had a more significant advantage than the manual capsulorrhexis group (p<0.001). Femtosecond laser performed capsulotomy with more precision and higher reliability than the manual continuous curvilinear capsulorrhexis.

Stimulation through afferent sensory input is necessary to improve voluntary functional movement in stroke patients. Dual-afferent sensory input, which combines electromyography-triggered functional electric stimulation (ETFES) and action observation, was investigated to determine its effects on voluntary movements in stroke patients. This study was conducted on 18 patients with left hemiplegia diagnosed between 6 and 24 months prior. The 9 subjects in the dual-afferent sensory input (DASI) group underwent ETFES with action observation training for 4 weeks (20 min/d, 5 d/wk), while the 9 control group subjects underwent functional electric stimulation (FES) for the same duration. The outcome measures were the movement-related cortical potential (MRCP), H-reflex, electromyography (EMG), and balance. The control and DASI groups showed significant increases in MRCP, muscle activity, and balance, while H-reflex was significantly decreased. MRCP and balance showed significant differences between DASI and control groups. DASI stimulates voluntary movement in patients, causes rapid activation of the cerebral cortex, and reduces excessive excitation of spinal motor neurons. Therefore, DASI, which stimulates voluntary movement, has a greater effect on brain activation in stroke patients.

Objective: To investigate the clinical effect of fallopian tube obstruction recanalization by ozone. Methods: Total 116 cases of patients undergoing the fallopian tube obstruction were randomly divided into the experimental group and control group, with 58 cases in each group. All patients underwent the interventional fallopian tube recanalization. The patients in the experimental group underwent the fallopian tube perfusion by the ozone water. Meanwhile, the patients in the control group were treated with the conventional anti-inflammatory and anti-adhesion drugs. After the follow-up visit for 6 months, the pregnancy rate and fallopian tube re-occlusion rate were counted and compared between the two groups. Meanwhile, the symptoms were evaluated and compared between the two groups after the operation for two weeks. Results: The success rate of fallopian tube recanalization was 93.1% (54/58), the pregnancy rate was 79.3% (46/58) and the recurrence rate was 5.2% (3/58) in the experimental group. While the success rate of fallopian tube recanalization was 91.4% (53/58), the pregnancy rate was 60.3% (35/58) and the recurrence rate was 17.2% (10/58) in the control group. Analysis showed that there was no significant difference in the recanalization success rate between the two groups (P>0.05). However, the pregnancy rate and re-occlusion rate in the experimental group were significantly lower than those of the control group (P<0.05), and the difference was statistically significant. There was no significant difference in the discomfort symptoms between the experimental group and control group (P>0.05). Conclusion: Fallopian tube recanalization by ozone perfusion can effectively increase the postoperative pregnancy rate and reduce the fallopian tube re-occlusion. PMID:28523024

The clinical impact of intraoperative autofluorescence-based identification of parathyroids using a near-infrared camera remains unknown. In a before and after controlled study, we compared all patients who underwent total thyroidectomy by the same surgeon during Period 1 (January 2015 to January 2016) without near-infrared (near-infrared- group) and those operated on during Period 2 (February 2016 to September 2016) using a near-infrared camera (near-infrared+ group). In parallel, we also compared all patients who underwent surgery without near-infrared during those same periods by another surgeon in the same unit (control groups). Main outcomes included postoperative hypocalcemia, parathyroid identification, autotransplantation, and inadvertent resection. The near-infrared+ group displayed significantly lower postoperative hypocalcemia rates (5.2%) than the near-infrared- group (20.9%; P < .001). Compared with the near-infrared- patients, the near-infrared+ group exhibited an increased mean number of identified parathyroids and reduced parathyroid autotransplantation rates, although no difference was observed in inadvertent resection rates. Parathyroids were identified via near-infrared before they were visualized by the surgeon in 68% patients. In the control groups, parathyroid identification improved significantly from Period 1 to Period 2, although autotransplantation, inadvertent resection and postoperative hypocalcemia rates did not differ. Near-infrared use during total thyroidectomy significantly reduced postoperative hypocalcemia, improved parathyroid identification and reduced their autotransplantation rate.

Autologous bone graft has been regarded as the criterion standard for the repair of alveolar cleft. However, the most prominent issue in alveolar cleft treatment is the high absorption rate of the bone graft. The authors' objective was to investigate the effects of an autologous iliac bone, bone marrow-derived mesenchymal stem cell, and platelet-rich fibrin mixture on the repair of dog alveolar cleft. Twenty beagle dogs with unilateral alveolar clefts created by surgery were divided randomly into four groups: group A underwent repair with an autologous iliac bone, bone marrow-derived mesenchymal stem cell, and platelet-rich fibrin mixture; group B underwent repair with autologous iliac bone and bone marrow-derived mesenchymal stem cells; group C underwent repair with autologous iliac bone and platelet-rich fibrin; and group D underwent repair with autologous iliac bone as the control. One day and 6 months after transplantation, the transplant volumes and bone mineral density were assessed by quantitative computed tomography. All of the transplants were harvested for hematoxylin and eosin staining 6 months later. Bone marrow-derived mesenchymal stem cells and platelet-rich fibrin transplants formed the greatest amounts of new bone among the four groups. The new bone formed an extensive union with the underlying maxilla in groups A, B, and C. Transplants with the bone marrow-derived mesenchymal stem cells, platelet-rich fibrin, and their mixture retained the majority of their initial volume, whereas the transplants in the control group showed the highest absorption rate. Bone mineral density of transplants with the bone marrow-derived mesenchymal stem cells, platelet-rich fibrin, and their mixture 6 months later was significantly higher than in the control group (p < 0.05), and was the highest in bone marrow-derived mesenchymal stem cells and platelet-rich fibrin mixed transplants. Hematoxylin and eosin staining showed that the structure of new bones formed the best in group A. Both bone marrow-derived mesenchymal stem cells and platelet-rich fibrin are capable of improving the repair of dog alveolar cleft, and the mixture of them is more potent than each one of them used singly for enhancing new bone regeneration.

AIM To determine the incidence and risk factors of secondary glaucoma after pediatric cataract surgery. METHODS Two hundred and forty nine eyes of 148 patients underwent cataract surgery without intraocular lens (IOL) implantation (group 1), and 220 eyes of 129 patients underwent cataract surgery with IOL implantation (group 2) retrospectively, were evaluated between 2000 and 2011. The outcome measure was the presence or absence of post-cataract surgery glaucoma, defined as an intraocular pressure (IOP) ≥26mmHg, as measured on at least two occasions along with corneal or optic nerve changes. RESULTS The mean follow-up periods of group 1 and 2 were (60.86±30.95) months (12-123 months) and (62.11±31.29) months (14-115 months) respectively. In group 1, 12 eyes of 8 patients (4.8%) developed glaucoma. None of the patients developed glaucoma after surgery in group 2. The mean age of the patients at the cataract surgery was (2.58±0.90) months (1 month-4 months) and the average period for glaucoma development after surgery was (9.50±4.33) months (4-16 months) in group 1. Three of the 12 glaucomatous eyes were controlled with antiglaucomatous medication and 9 eyes underwent trabeculectomy+mitomycin C surgery. One patient underwent a second trabeculectomy + mitomycin C operation for both of his eyes. CONCLUSION The incidence of glaucoma after pediatric cataract surgery is very low in patients in whom IOL is implanted. The aphakic eyes after pediatric cataract surgery are at an increased risk for glaucoma development particularly if they underwent surgery before 4 months of age. PMID:23638427

The aim of the present study was to compare the effectiveness of 25G vitrectomy to standard 20G vitrectomy for treatment of Terson syndrome under Resight non-contact wide-angle lenses. This was a case-control study of 20 patients with Terson syndrome (study group) that underwent 25G vitrectomy under Resight non-contact wide-angle lenses, with those of 20 matched patients that underwent 20G vitrectomy (control group). Medical records were reviewed from between July 2011 and October 2013. Data included results of the Early Treatment Diabetic Retinopathy Study examination, ophthalmology B-scan ultrasonography and fundus photography. The mean age, follow-up time, the preoperative visual acuity of LogMAR and the preoperative intraocular pressure (IOP) were all comparable in the two groups (all P>0.05). There were statistically significant differences in postoperative visual acuity of LogMAR compared with preoperative visual acuity (P<0.001) in both groups, but no difference between the groups (P=0.845). However, the operative times (13.5 min in study group vs. 42 min in control group) and post-operative IOP at day 1 (13.5 vs. 20 mmHg) were significantly reduced in the study group compared to the control group (P<0.001). Therefore, the present findings suggest that 25G Vitrectomy for Terson syndrome under Resight non-contact wide-angle lenses can achieve a significantly shorter operative time and lower post-operative IOP compared with 20G Vitrectomy.

The aim of this study was to analyze and compare the vocal quality in patients who underwent either submucosal turbinectomy or radiofrequency cauterization. In this study, we enrolled 60 patients diagnosed with inferior concha hypertrophy. These patients were divided into two groups by using computer program "Research Randomizer." Of the 60 patients, 30 underwent submucosal inferior turbinoplasty and 30 underwent radiofrequency cauterization. The control group was composed of 30 healthy adults with no nasal or upper aerodigestive system pathology. The patients were checked at weeks 1, 2, and 4. Voice records were taken before the procedure and at week 4 postprocedure. The mean age of patients in the inferior turbinoplasty group was 29.4 years (range: 19-42 years); in the radiofrequency group, it was 30.30 years (range: 18-50 years). There was no statistical difference in age between groups. In the inferior turbinoplasty group, there were 16 male and 14 female patients, and in the radiofrequency group, there were 13 male and 17 female patients. There was no significant difference in the number of males and females between groups. Voice professionals, especially singers, actors, and actresses, should be informed about possible voice changes before undergoing endonasal surgery because these individuals are more sensitive to changes in resonance organs. We believe that voice quality should be regarded as a highly important parameter when measuring the success of endonasal surgery. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

Citrus aurantium is rich in flavonoids, which may prevent osteosarcoma progression, but its related molecular mechanism remains unclear. Flavonoids were extracted from C. aurantium and purified by reparative HPLC. Each fraction was identified by using electrospray ionisation mass spectrometry (ESI-MS). Three main components (naringin, naringenin, and hesperetin) were isolated from C. aurantium . Naringenin inhibited the growth of MG-63 cells, whereas naringin and hesperetin had no inhibitory function on cell growth. ROS production was increased in naringin- and hesperetin-treated groups after one day of culture while the level was always lowest in the naringenin-treated group after three days of culture. 95 osteosarcoma patients who underwent surgery were assigned into two groups: naringenin group (NG, received 20 mg naringenin daily, n = 47) and control group (CG, received 20 mg placebo daily, n = 48). After an average of two-year follow-up, osteosarcoma volumes were smaller in the NG group than in the CG group ( P > 0.01). The rate of osteosarcoma recurrence was also lower in the NG group than in CG group. ROS levels were lower in the NG group than in the CG group. Thus, naringenin from Citrus aurantium inhibits osteosarcoma progression and local recurrence in the patients who underwent osteosarcoma surgery by improving antioxidant capability.

Initiating renal replacement therapy in late referred patients with central venous catheter (CVC) hemodialysis (HD) causes serious complications. In urgent start peritoneal dialysis, initiating peritoneal dialysis (PD) within 14 days of catheter insertion still needs HD with CVC. We initiated Emergent start PD (ESPD) with Automated PD (APD) at our center within 48 h from the time of presentation. A prospective, case-controlled, intention-to-treat study with 56 patients was conducted between March 2016 and August 2017. Group A (24 patients) underwent conventional PD 14 days after catheter insertion. Group B (32 patients), underwent ESPD with APD. Exit site leak (ESL), catheter blockage, and peritonitis at 90 days were primary outcomes. Technique survival was secondary outcome. Baseline characteristics were similar with 3 episodes of ESLs (9.4%) in the study group and none in the control group (p = 0.123). Catheter blockage (16.7%-Group A, 25%-Group B) and peritonitis (none vs. 9.4% in study group) were similar in terms of statistical details just as technique survival (95%-Group A, 88.2%-Group B at 90 days). ESPD with APD in the unplanned patient is an appropriate approach. © 2018 S. Karger AG, Basel.

Self-expandable metal stents (SEMSs) have been used as palliative treatment or bridge to surgery for obstructions caused by colorectal cancer (CRC). We assessed the long-term outcomes of palliative SEMSs and evaluated the risk factors influencing complications. One hundred and seventy-five patients underwent SEMS placement for acute malignant colorectal obstruction. Of the 72 patients who underwent palliative treatment for primary CRC, 30 patients received chemotherapy (CT) for primary cancer (CT group) and 42 underwent best supportive treatment (BST) without CT (BST group). There was a significant difference in late migration between the CT group and the BST group (20.0% in CT group, 2.4% in BST group, p = 0.018). Response to CT influenced the rate of late obstruction (0% in disease control, 35.7% in disease progression, p = 0.014). However, late obstruction was not associated with stent properties, such as diameter or type (≤22 mm vs. >22 mm, 13.5% vs. 14.3%, p = 1.00; uncovered stent vs. covered stent, 15.5% vs. 7.1%, p = 0.675) and migration (≤22 mm vs. >22 mm, 16.2% vs. 2.9%, p = 0.108; uncovered stent vs. covered stent, 8.6% vs. 14.3%, p = 0.615) in palliative SEMS. The administration of CT increases the rate of stent migration, and disease control by CT can reduce the risk of obstruction by maintaining the luminal patency of palliative SEMSs.

Intravenous (IV) acetaminophen may be an effective component of multimodal postoperative pain management. The primary objective of this study was to evaluate the impact of IV acetaminophen on total opioid use in postoperative patients. The secondary objective was to evaluate the effect of IV acetaminophen on hospital length of stay. This retrospective, case-control study evaluated the impact of IV acetaminophen on total opioid use in surgical patients. Patients were included if they received at least one perioperative dose of IV acetaminophen and underwent a surgical knee procedure. Controls were matched and randomly selected based on procedure type, age, and severity of illness. Postoperative opioids were converted into oral morphine equivalents, and overall use was compared between groups. One hundred patients were enrolled, with 25 patients receiving IV acetaminophen and 75 matched controls. A total of 135 mg versus 112.5 mg oral morphine equivalents were used in the IV acetaminophen group and control group, respectively (p=0.987). There were 45 mg/day oral morphine equivalents used in the IV acetaminophen group versus 37.5 mg in the control group (p=0.845). The median hospital length of stay in both groups was 3 days (p=0.799). IV acetaminophen did not significantly decrease postoperative opioid use in patients who underwent surgical knee procedures. In addition, there was a nonsignificant trend toward increased opioid use in the IV acetaminophen group. There was no significant difference in hospital length of stay between the IV acetaminophen group and the control group. These findings require further study in larger patient populations and in other orthopedic procedures that typically require longer hospital stays. © 2014 Pharmacotherapy Publications, Inc.

Changes in pulmonary dynamics following laparotomy are well documented. Deep breathing exercises, with or without incentive spirometry, may help counteract postoperative decreased vital capacity; however, the evidence for the role of incentive spirometry in the prevention of postoperative atelectasis is inconclusive. Furthermore, data are scarce regarding the prevention of postoperative atelectasis in sub-Saharan Africa. To determine the effect of the use of incentive spirometry on pulmonary function following exploratory laparotomy as measured by forced vital capacity (FVC). This was a single-center, randomized clinical trial performed at Kamuzu Central Hospital, Lilongwe, Malawi. Study participants were adult patients who underwent exploratory laparotomy and were randomized into the intervention or control groups (standard of care) from February 1 to November 30, 2013. All patients received routine postoperative care, including instructions for deep breathing and early ambulation. We used bivariate analysis to compare outcomes between the intervention and control groups. Adult patients who underwent exploratory laparotomy participated in postoperative deep breathing exercises. Patients in the intervention group received incentive spirometers. We assessed pulmonary function using a peak flow meter to measure FVC in both groups of patients. Secondary outcomes, such as hospital length of stay and mortality, were obtained from the medical records. A total of 150 patients were randomized (75 in each arm). The median age in the intervention and control groups was 35 years (interquartile range, 28-53 years) and 33 years (interquartile range, 23-46 years), respectively. Men predominated in both groups, and most patients underwent emergency procedures (78.7% in the intervention group and 84.0% in the control group). Mean initial FVC did not differ significantly between the intervention and control groups (0.92 and 0.90 L, respectively; P=.82 [95% CI, 0.52-2.29]). Although patients in the intervention group tended to have higher final FVC measurements, the change between the first and last measured FVC was not statistically significant (0.29 and 0.25 L, respectively; P=.68 [95% CI, 0.65-1.95]). Likewise, hospital length of stay did not differ significantly between groups. Overall postoperative mortality was 6.0%, with a higher mortality rate in the control group compared with the intervention group (10.7% and 1.3%, respectively; P=.02 [95% CI, 0.01-0.92]). Education and provision of incentive spirometry for unmonitored patient use does not result in statistically significant improvement in pulmonary dynamics following laparotomy. We would not recommend the addition of incentive spirometry to the current standard of care in this resource-constrained environment. clinicaltrials.gov Identifier: NCT01789177.

In order to investigate the sleep quality and influencing factors in patients with Parkinson's disease (PD), 201 PD patients were enrolled and underwent extensive clinical evaluations. Subjective sleep evaluation was assessed using the Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS). It was found that poor sleep quality (77.11%) and excessive daytime sleepiness (32.34%) were commonly seen in PD patients and positively correlated with disease severity. Then 70 out of the 201 PD patients and 70 age- and sex-matched controls underwent a polysomnographic recording. The parameters were compared between PD group and control group and the influencing factors of sleep in PD patients were analyzed. The results showed that sleep efficiency (SE) was significantly decreased (P<0.01), and sleep latency (SL) and the arousal index (AI) were increased (P<0.05) in the PD group as compared with those in the control group. SE and total sleep time (TST) were positively correlated with the Hoehn and Yahr (H&Y) stage. There was significant difference in the extent of hypopnea and hypoxemia between the PD group and the control group (P<0.05). Our results indicate that PD patients have an overall poor sleep quality and a high prevalence of sleep disorder, which may be correlated with the disease severity. Respiratory function and oxygen supply are also affected to a certain degree in PD patients.

Quadriceps palsy is mainly caused by proximal lesions in the femoral nerve. The obturator nerve has been previously used to repair the femoral nerve, although only a few reports have described the procedure, and the outcomes have varied. In the present study, we aimed to confirm the feasibility and effectiveness of this treatment in a rodent model using the randomized control method. Sixty Sprague-Dawley rats were randomized into two groups: the experimental group, wherein rats underwent femoral neurectomy and obturator nerve transfer to the femoral nerve motor branch; and the control group, wherein rats underwent femoral neurectomy without nerve transfer. Functional outcomes were measured using the BBB score, muscle mass, and histological assessment. At 12 and 16 weeks postoperatively, the rats in the experimental group exhibited recovery to a stronger stretch force of the knee and higher BBB score, as compared to the control group (p < 0.05). The muscle mass and myofiber cross-sectional area of the quadriceps were heavier and larger than those in the control group (p < 0.05). A regenerated nerve with myelinated and unmyelinated fibers was observed in the experimental group. No significant differences were observed between groups at 8 weeks postoperatively (p > 0.05). Obturator nerve transfer for repairing femoral nerve injury was feasible and effective in a rat model, and can hence be considered as an option for the treatment of femoral nerve injury.

Identifying effective interventions is vitalin preventing slip-induced fall accidents in older adults. The purpose of the current study was to evaluate the efficacy of moveable platform training in improving recovery reactions and reducing fall frequency in older adults. Twenty-four older adults were recruited and randomly assigned to two groups (training and control). Both groups underwent three sessions including baseline slip, training, and transfer of training on a slippery surface. Both groups experienced two slips on a slippery surface, one during the baseline and the other (after two weeks) during the transfer of training session. In the training session, the training group underwent twelve simulated slips using a moveable platform while the control group performed normal walking trials. Kinematic, kinetic, and EMG data were collected during all the sessions. Results indicated a reduced incidence of falls in the training group during the transfer of training trial as compared to the control group. The training group was able to transfer proactive and reactive control strategies learned during training to the second slip trial. The proactive adjustments include increased center-of-mass velocity and transitional acceleration after training. Reactive adjustments include reduction in muscle onset and time to peak activations of knee flexors and ankle plantarflexors, reduced ankle and knee coactivation, reduced slip displacement, and reduced time to peak knee flexion, trunk flexion, and hip flexion velocities. In general, the results indicated a beneficial effect of perturbation training in reducing slip severity and recovery kinematics in healthy older adults. PMID:22134467

Clopidogrel (Plavix) usage is increasing, primarily for the management of patients with cerebrovascular symptoms and for those receiving drug-eluting coronary artery stents. A significant percentage of these patients will require carotid endarterectomy (CEA) while they are receiving clopidogrel. Recent data have demonstrated an increased incidence of coronary stent thrombosis when clopidogrel is discontinued. The objective of this study was to determine if CEA could be performed safely while patients are continued on clopidogrel therapy. A retrospective cohort design was employed to review consecutive patients who underwent CEA over a 24-month period ending March 2007. Patients were divided into two groups based on the perioperative use of clopidogrel. Preoperative demographics and postoperative results were compared between the two groups and statistically analyzed. Of the 100 patients who underwent CEA, 19 were taking clopidogrel within 5 days of surgery. This comprised the study group. The control group consisted of the 81 patients who did not receive clopidogrel. Heparin anticoagulation was routinely utilized prior to clamping in both groups. Demographics were similar between the groups. There were no statistical differences in morbidity or mortality between the control group and the clopidogrel group. Combined stroke/death rates were equivalent between the two groups (1.2% control vs. 0% clopidogrel). One hematoma developed in the control group, which did not require operative intervention. In this series, our results suggest that patients concurrently on clopidogrel can safely undergo CEA without increased risk of hematoma or neurological complications. In view of recent data demonstrating adverse outcomes in patients discontinuing clopidogrel, this study is useful in optimally managing this group of patients.

Calculi from patients with musculoskeletal (MS) anomalies who are largely immobile and prone to urinary infections have been traditionally composed primarily of struvite and carbonate apatite. Because of substantial improvements in the care of these patients in recent decades, stone etiology may have shifted from infectious to metabolic. We assessed the composition of renal calculi and metabolic characteristics in a contemporary cohort of patients with MS anomalies who underwent percutaneous nephrolithotomy (PCNL). Retrospective analysis of patients who underwent PCNL between April 1999 and June 2009 and had follow-up 24-hour urine studies was performed. Patients with MS anomalies included spinal cord injury, myelomeningocele, muscular dystrophy, multiple sclerosis, cerebral palsy, or other clinical syndromes causing kyphoscoliosis and contractures. Our cohort included 33 patients with MS anomalies and 334 consecutive patients as a control group who underwent PCNL and had metabolic workup. Stones were infectious in etiology in 18.4% and 6.2% in MS and control groups, respectively. Thus, most patients harbored stones of metabolic origin. Metabolic stones in the MS group were composed of 52.7% hydroxyapatite, 10.5% calcium oxalate, 7.9% brushite, 2.6% uric acid, 0% cystine, and 7.9% other. Metabolic stones in the control group were 50.5% calcium oxalate, 16.4% hydroxyapatite, 11.5% brushite, 10.8% uric acid, 4.3% cystine, and 0.3% other. Mean 24-hour urine values for patients with metabolic stones in MS/control groups were volume 2.18/1.87 L/d, pH 6.78/6.05, calcium to creatinine ratio 220/151 mg/g, and oxalate 44.8/39.5 mg/d. Although patients with MS anomalies are traditionally thought to harbor infection-related calculi, most will be found to have calculi of metabolic etiology. The incidence of calcium phosphate stones is high in this group of patients, perhaps reflecting their high urinary pH.

Treatment of severe egg allergy is avoidance of hen's egg (HE) and carrying self-injectable epinephrine. Specific oral tolerance induction (SOTI) seems a promising alternative treatment. However, some aspects of SOTI are still considered experimental. We evaluated the efficacy and safety of an original 6-month SOTI protocol in children with very severe HE allergy using raw HE emulsion. Twenty children (age range: 5-11 yr) were randomized equally into a SOTI treatment group and a control group. The treatment group started SOTI and underwent a second challenge 6 months later. Control children were kept on an egg-free diet for 6 months and then underwent a second challenge. After 6 months, 9/10 children of the SOTI group (90%) achieved partial tolerance (at least 10 ml, but <40 ml of raw HE emulsion, in a single dose) and 1 (10%) was able to tolerate only 5 ml (no tolerance). After 6 months, nine control children tested positive to the second challenge at a dose ≤0.9 ml of raw HE emulsion, and one reacted to 1.8 ml (SOTI vs. control group p<0.0001). All children in the SOTI group had side effects, but no child had a grade 5 reaction according to the Sampson grading. Six months of SOTI with raw HE emulsion resulted in partial tolerance, with regular intake, in a significant percentage of children with severe egg allergy. © 2012 John Wiley & Sons A/S.

Objective To evaluate changes in corneal astigmatism in patients undergoing orbital decompression surgery. Methods This retrospective, non randomized comparative study involved 42 eyes from 21 patients with thyroid ophthalmopathy who underwent orbital decompression surgery between September 2011 and September 2014. The 42 eyes were divided into three groups: control (9 eyes), two-wall decompression (25 eyes), and three-wall decompression (8 eyes). The control group was defined as the contralateral eyes of nine patients who underwent orbital decompression surgery in only one eye. Corneal topography (Orbscan II), Hertel exophthalmometry, and intraocular pressure were measured at 1 month before and 3 months after surgery. Corneal topographic parameters analyzed were total astigmatism (TA), steepest axis (SA), central corneal thickness (CCT), and anterior chamber depth (ACD). Results Exophthalmometry values and intraocular pressure decreased significantly after the decompression surgery. The change (absolute value (|x|) of the difference) in astigmatism at the 3 mm zone was significantly different between the decompression group and the controls (p = 0.025). There was also a significant change in the steepest axis at the 3 mm zone between the decompression group and the controls (p = 0.033). An analysis of relevant changes in astigmatism showed that there was a dominant tendency for incyclotorsion of the steepest axis in eyes that underwent decompression surgery. Using Astig PLOT, the mean surgically induced astigmatism (SIA) was 0.21±0.88 D with an axis of 46±22°, suggesting that decompression surgery did change the corneal shape and induced incyclotorsion of the steepest axis. Conclusions There was a significant change in corneal astigmatism after orbital decompression surgery and this change was sufficient to affect the optical function of the cornea. Surgeons and patients should be aware of these changes. PMID:26352432

This study aimed to evaluate the efficacy of low-level laser therapy (LLLT) and light-emitting diodes (LEDs) for reducing pain in hyperglycemic and normoglycemic patients who underwent coronary artery bypass surgery with internal mammary artery grafts. This study was conducted on 120 volunteers who underwent elective coronary artery bypass graft (CABG) surgery. The volunteers were randomly allocated to four different groups of equal size (n = 30): control, placebo, LLLT [λ = 640 nm and spatial average energy fluence (SAEF) = 1.06 J/cm(2)], and LED (λ = 660 ± 20 nm and SAEF = 0.24 J/cm(2)). Participants were also divided into hyperglycemic and normoglycemic subgroups, according to their fasting blood glucose test result before surgery. The outcome assessed was pain during coughing by a visual analog scale (VAS) and the McGill Pain Questionnaire. The patients were followed for 1 month after the surgery. The LLLT and LED groups showed a greater decrease in pain, with similar results, as indicated by both the VAS and the McGill questionnaire (p ≤ 0.05), on the 6th and 8th postoperative day compared with the placebo and control groups. The outcomes were also similar between hyperglycemic and normoglycemic patients. One month after the surgery, almost no individual reported pain during coughing. LLLT and LED had similar analgesic effects in hyperglycemic and normoglycemic patients, better than placebo and control groups.

This study was conducted to determine the efficacy of mindfulness-based cognitive therapy (MBCT) on psychological symptoms and quality of life (QoL) in patients with systemic lupus erythematosus (SLE). We conducted a randomized single-blind clinical trial in patients with SLE referred from the Imam Ali Clinic in Shahrekord, southwest Iran. The patients (46 in total in two groups of 23 each) were randomly assigned into the experimental and control groups. Both groups underwent routine medical care, and the experimental group underwent eight group sessions of MBCT in addition to routine care. The patient , s QoL was assessed using the General Health Questionnaire-28 and 36-Item Short Form Health Survey before, after, and six months after intervention (follow-up). A significant difference was seen in psychological symptoms and QoL between MBCT and control groups immediately after the intervention and at follow-up ( p ≤ 0.050). However, the difference was not significant for the physical components of QoL ( p ≥ 0.050). MBCT contributed to decreased psychological symptoms and improved QoL in patients with SLE with a stable effect on psychological symptoms and psychological components of QoL, but an unstable effect on physical components.

Thoracic trauma resulting in hemothorax (HTx) is typically managed with thoracostomy tube (TT) placement; however, up to 20% of patients develop retained HTx which may necessitate further intervention for definitive management. Although optimal management of retained HTx has been extensively researched, little is known about prevention of this complication. We hypothesized that thoracic irrigation at the time of TT placement would significantly decrease the rate of retained HTx necessitating secondary intervention. A prospective, comparative study of patients with traumatic HTx who underwent bedside TT placement was conducted. The control group consisted of patients who underwent standard TT placement, whereas the irrigation group underwent standard TT placement with immediate irrigation using 1 L of warmed sterile 0.9% saline. Patients who underwent emergency thoracotomy, those with TTs removed within 24 hours, or those who died within 30 days of discharge were excluded. The primary end point was secondary intervention defined by additional TT placement or operative management for retained HTx. A propensity-matched analysis was performed with scores estimated using a logistic regression model based on age, sex, mechanism of injury, Abbreviated Injury Scale chest score, and TT size. In over a 30-month period, a total of 296 patients underwent TT placement for the management of traumatic HTx. Patients were predominantly male (79.6%) at a median age of 40 years and were evenly split between blunt (48.8%) and penetrating (51.2%) mechanisms. Sixty (20%) patients underwent thoracic irrigation at time of initial TT placement. The secondary intervention rate was significantly lower within the study group (5.6% vs. 21.8%; OR, 0.16; p < 0.001). No significant differences in TT duration, ventilator days, or length of stay were noted between the irrigation and control cohort. Thoracic irrigation at the time of initial TT placement for traumatic HTx significantly reduced the need for secondary intervention for retained HTx. Therapeutic Study, Level III.

Randomized controlled trial. A total of 52 older subjects selected for internal fixation due to extra-capsular hip fracture were randomized to be included in an experimental ( n = 26) and control group ( n = 26). The experimental group underwent a rehabilitation programme based on balance task-specific training. The control group underwent general physiotherapy, including open kinetic chain exercises and walking training. Both groups individually followed programmes of 90-minute sessions five times/week for three weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), a Pain Numerical Rating Scale, the Berg Balance Scale, the Functional Independence Measure and the 36-item Short-Form Health Survey. The participants were evaluated before and after training, and after 12 months. Significant effects of time, group and time × group were found for all outcome measures in favour of the experimental group. A clinically important between-group difference of 25 points was achieved after training and at follow-up in terms of the primary outcome (WOMAC function before treatment, after treatment and at follow-up was 84.8 (3.7), 39.8 (4.9) and 35.7 (6.2) for the experimental group and 80.9 (5.7), 65.2 (7.1) and 61.0 (11.1) for the control group). An inpatient rehabilitation programme based on balance task-specific training is useful in improving physical function, pain, ADL and quality of life in older patients after hip fracture.

Extracorporeal shock wave therapy (ESWT) is known to accelerate the healing of musculoskeletal tissue. The purpose of this study was to test the hypothesis that ESWT stimulates rotator cuff healing after arthroscopic repair. Seventy-one consecutive patients with a small- to large-sized rotator cuff tear underwent arthroscopic rotator cuff repair. The patients were randomized into two groups: 35 patients underwent ESWT at 6 weeks after surgery (ESWT group) and 36 patients did not (control group). Cuff integrity was evaluated with computed tomographic arthrography at 6 months after surgery. Constant and UCLA scores were measurable outcomes. All patients were available for a minimum one-year follow-up. The mean age of the ESWT and control groups was 59.4 (SD: 7.7) and 58.6 years (SD: 7.8) (n.s.). There were no significant differences in tear size and repair method between the two groups (n.s.). The mean Constant and UCLA scores, respectively, increased from 54.6 to 90.6 (P < 0.001) and from 18.5 to 27.4 (P < 0.001) in the ESWT group, and from 58.9 to 89.3 (P < 0.001) and 18.5 to 27.4 in the control group. Computed tomographic arthrography was performed in 26 patients from the ESWT group and 24 from the control group, and cuff integrity was maintained in 46 out of 50 patients. Definite re-tear was observed in two patients of the ESWT group and four of the controls. There were no complications associated with ESWT. This study failed to prove that ESWT stimulates rotator cuff healing after arthroscopic rotator cuff repair. Additional ESWT after rotator cuff repair could theoretically be advantageous, and it was proven to be safe in this study. II.

This study was conducted to develop an Empowerment Education Program (EEP) for kidney transplant patients and to test the program's effects on uncertainty, self-care ability, and compliance. The research was conducted using a nonequivalent control group with a pretest-posttest design. The participants were 53 outpatients (experimental group: 25, control group: 28) who were receiving hospital treatment after kidney transplants. After the pre-test, patients in the experimental group underwent a weekly EEP for six weeks. The post-test was conducted immediately after, and four weeks after the program's completion in the same manner as the pre-test. For the control group, we conducted a post-test six and ten weeks after the pre-test, without and program intervention. A repeated measure ANOVA was performed to compare the change scores on main outcomes. Uncertainty was significantly lower in the experimental group than in the control group, both immediately after (t=-3.84, p=<.001) and 4 weeks after (t=-4.51 p=<.001) the program, whereas self-care ability (t=5.81, p=<.001), (t=5.84, p=<.001) and compliance (t=5.07, p=<.001), (t=5.45, p=<.001) were significantly higher. Kidney transplant patients who underwent an EEP showed a decrease in uncertainty and an improvement in self-care ability and compliance. Thus, our findings confirmed that an EEP can be an independent intervention method for improving and maintaining the health of kidney transplant patients. © 2017 Korean Society of Nursing Science

To report our intrapartum experience with routine delivery at 38 weeks of gestation of A-2 diabetic pregnancies requiring primarily oral hypoglycemic therapy. This retrospective study consisted of 143 consecutive women with gestational diabetes not controlled with diet alone (A-2). Each underwent a routine trial of labor at 38 weeks of gestation. The preinduction condition of the cervix, need for oxytocin, and primary cesarean rates were primary endpoints. For comparison, a control group during that same period consisted of 137 consecutive diet-controlled diabetic (A-1) pregnancies with the same eligibility criteria who underwent expectant management at 38 weeks. The study group was more likely to have an unfavorable cervix (75% versus 45%; p < 0.001) and to require oxytocin (76% versus 56%; p < 0.001). Early onset meconium was less common in the study group (3.5% versus 13.1%; p < 0.01). Primary cesarean rates were low and not different between the study and control groups (12.7% versus 11.7%; p < 0.8). The only stillbirth was in the control group and was associated with a tight double nuchal cord encirclement. Mean birth weights and the frequency of birth weights > 4000 g were not different between groups. Shoulder dystocia, low Apgar scores, and admissions to the special care nursery were infrequent in either group. No respiratory difficulties requiring resuscitation or prolonged nursery care were encountered. Routine delivery at 38 weeks in an A-2 diabetic population is not associated with additional intrapartum morbidity or a greater need for cesarean delivery.

Two studies have demonstrated an analgesic effect of maternal milk odor in preterm neonates, without specifying the method of olfactory stimulation. Research aim: This study aimed to assess the analgesic effect of maternal milk odor in preterm neonates by using a standardized method of olfactory stimulation. This trial was prospective, randomized, controlled, double blinded, and centrally administered. The inclusion criteria for breastfed infants included being born between 30 and 36 weeks + 6 days gestational age and being less than 10 days postnatal age. There were two groups: (a) A maternal milk odor group underwent a venipuncture with a diffuser emitting their own mother's milk odor and (2) a control group underwent a venipuncture with an odorless diffuser. The primary outcome was the Premature Infant Pain Profile (PIPP) score, with secondary outcomes being the French scale of neonatal pain-Douleur Aiguë du Nouveau-né (DAN) scale-and crying duration. All neonates were given a dummy. Our study included 16 neonates in the maternal milk odor group and 17 in the control group. Neonates exposed to their own mother's milk odor had a significantly lower median PIPP score during venipuncture compared with the control group (6.3 [interquartile range (IQR) = 5-10] versus 12.0 [IQR = 7-13], p = .03). There was no significant difference between the DAN scores in the two groups ( p = .06). Maternal milk odor significantly reduced crying duration after venipuncture (0 [IQR = 0-0] versus 0 [IQR = 0-18], p = .04). Maternal milk odor has an analgesic effect on preterm neonates.

The aim of this study was to compare the outcome of two single-incision mini-slings (the Contasure-Needleless [C-NDL] and the endopelvic free anchorage) with the standard midurethral transobturator tension-free vaginal tape (TVT-O) procedure. A double blind randomized controlled study was conducted at Ain Shams University Maternity Hospital from August 2014 until July 2015. A total of 209 patients were randomized into three groups. The first group underwent the TVT-O procedure, the second group underwent the endopelvic free anchorage procedure and the third group underwent the C-NDL procedure. Patients were followed up for 12 months in terms of subjective cure, objective cure, and complications rate. After 12 months of follow-up, there were no differences among the three groups in terms of objective cure rate, subjective cure rate, patient satisfaction, or incidence of complications (de novo urge, hemorrhage, infection, and mesh erosion). The C-NDL was associated with a shorter operative time (P < 0.001) and less blood loss (P = 0.021) than the standard TVT-O. The new single-incision mini-slings showed similar efficacy and patient acceptance to that of the standard TVT-O for up to 12 months postoperatively with no difference in the complications rate. The C-NDL is associated with shorter operative time and less blood loss. © 2016 Japan Society of Obstetrics and Gynecology.

The aim of this study is to improve the results of surgical treatment of acute bowel obstruction caused by rectal cancer and to reduce the period of full recovery of patients. The presented research included 73 patients (study group) with rectal cancer who underwent emergent anterior resection of rectum with loop ileostomy and intra-operative decompression of colon. Patients of this group were compared to a group of 68 patients (control group) with the same diagnosis who underwent Hartmann's procedure. There was no essential difference between the two groups in the quantity of postoperative complications. However the results indicate significant difference in reversal rates and time to reversal. Thus, the technique of low anterior resection with intraoperative decompression and ileostomy that we used improves outcomes, significantly reduces the period of full recovery.

Cardiac calcification is associated with coronary artery disease, arrhythmias, conduction disease, and adverse cardiac events. Recently, we have described an echocardiographic-based global cardiac calcification scoring system. The objective of this study was to evaluate the severity of cardiac calcification in patients with permanent pacemakers as based on this scoring system. Patients with a pacemaker implanted within the 2-year study period with a previous echocardiogram were identified and underwent blinded global cardiac calcium scoring. These patients were compared to matched control patients without a pacemaker who also underwent calcium scoring. The study group consisted of 49 patients with pacemaker implantation who were compared to 100 matched control patients. The mean calcium score in the pacemaker group was 3.3 ± 2.9 versus 1.8 ± 2.0 (P = 0.006) in the control group. Univariate and multivariate analysis revealed glomerular filtration rate and calcium scoring to be significant predictors of the presence of a pacemaker. Echocardiographic-based calcium scoring correlates with the presence of severe conduction disease requiring a pacemaker. © 2012, Wiley Periodicals, Inc.

To evaluate the results of cataract surgery in patients with RP because retinitis pigmentosa is one of the disease entities that belongs to tapeto-retinal degenerations. The occurrence of RP appearance is 1:4000 to 1:3000. Twenty patients with RP (7 women and 13 men, 33 eyes), who underwent cataract surgery were examined retrospectively. Average age in our group was 46.6 years. Visual acuity, intraocular pressure, slip lamp examination, fundus examination, cataract morphology, visual field were taken before surgery and on discharge, on the basis of medical documentation. Control examination was taken, on average, eighty one months after cataract surgery. Nine eyes were operated by phacoemulsification, 24 eyes by means of extracapsular cataract extraction. In the same way control group of 18 patients who underwent cataract surgery without RP (33 eyes) was examined. In RP group in 63.6% patients on discharge from the hospital and in 60.6% patients during the control examination, improvement of visual acuity was revealed. Deterioration was noted in 18.2% of patients on discharge from hospital and in 24.2% of patients during the control examination. In the control group improvement of visual acuity was revealed in 90.9% of patients on discharge and in 97% patients during the control examination, whereas deterioration of visual acuity occurred in 6.1% patients on discharge and in 3% patients during the check examination. In patients with retinitis pigmentosa cataract occurs earlier then in the control group. Cataract surgery for relatively minor opacities is beneficial in patients with RP, and causes improvement of visual acuity in most of eyes undergoing surgery.

The clinical presentation, management and outcome of all patients with bile duct injury who presented to our tertiary care centre at various stages after cholecystectomy were analyzed. The patients were categorized into three groups: group A-patients in whom the injury was detected during cholecystectomy, group B-patients who presented within 2 weeks of cholecystectomy and group C-patients who presented after 2 weeks of cholecystectomy. Our team acted as rescue surgeons and performed 'on-table' repair for injuries occurring in another unit or in another hospital. Strasberg classification of bile duct injury was followed. In group A, partial and complete transections were managed by repair over T-tube and high hepaticojejunostomy, respectively. Patients in group B underwent endoscopic retrograde cholangiogram and/or magnetic resonance cholangiogram to evaluate the biliary tree. Those with intact common bile duct underwent endoscopic papillotomy and stenting in addition to drainage of intra-abdominal collection when present. For those with complete transection, early repair was considered if there was no sepsis. In presence of intra-abdominal sepsis an attempt was made to create controlled external biliary fistula. This was followed by hepatico jejunostomy at least after 3 months. Group C patients underwent hepaticojejunostomy at least 6 weeks after the injury. The outcome was graded into three categories: grade A-no clinical symptoms, normal LFT; grade B-no clinical symptoms, mild derangement of LFT or occasional episodes of pain or fever; grade C-pain, cholangitis and abnormal LFT; grade D-surgical revision or dilatation required. Fifty nine patients were included in the study and the distribution was group A-six patients, group B-33 patients and group C-20 patients. In group A, one patient with complete transection of the right hepatic duct (type C) and partial injury to left hepatic duct (LHD) underwent right hepaticojejunostomy and repair of the LHD over stent. Two patients with type D and three patients with type E 2 injury underwent repair over T-tube and hepaticojejunostomy, respectively. In group B, all except one of the 18 patients with type A injury underwent endoscopic papillotomy and stenting. The bile leak subsided at a mean interval of 8 days in all, except one patient who died of fulminant sepsis. Of the 15 patients with type E injury, five underwent hepaticojejunostomy after a minimum gap of 3 months. Early repair was considered in 10 patients. Twenty patients in group C underwent hepaticojejunostomy. In a mean follow-up of 40 months, the outcome was grade A in 54 patients, grade B in three patients (one from each of the three groups) and grade D in one patient (group C). The latter patient with a type E3 injury developed recurrent stricture and cholangitis necessitating percutaneous transhepatic dilatation. The high success rate of bile duct repair in the present study can be attributed to the appropriate timing, meticulous technique and the tertiary care experience.

To evaluate emergency SWL for the treatment of upper urinary-tract stones causing renal colic. Between January 1999 and June 2003, 53 patients with a mean age of 46.6 years (range 22-65 years) were enrolled. The inclusion criteria were acute renal colic, radiopaque 5-mm to 1.5-cm calculi in the ureteropelvic junction (N=10) or upper ureter (N=43), and no evidence of urinary-tract infection or acute renal failure. The mean stone size was 7.14 mm (range 5-13 mm). Patients were randomly assigned to the control (N=28) and study (N=25) groups using previously prepared cards in envelopes. Patients in the study group underwent emergency SWL, while patients in the control group underwent scheduled SWL within 30 days. Stone status was evaluated 4 weeks after lithotripsy. There was no significant difference between the control and study groups with respect to age, sex, stone location or volume, renal obstruction, or days spent in the hospital for pain control. Available fragments of stones were sent for infrared spectroscopy. Preoperative and postoperative data were compared in the two groups using SPSS 10.0 statistical software. The SWL treatment lasted 50+/-11 minutes. The stone-free rates were 72% and 64% and the efficiency quotients were 53% and 44% in study and control groups, respectively. Patients in the control group spent more time in the hospital (P=0.014) and in recovery at home (P=0.011). Emergency SWL for acute renal colic caused by upper-ureteral stones is a safe procedure and offers effective release from pain and obstruction. It also decreases hospitalization days and hastens return to normal activity.

Eustachian tube dysfunction and sleep-disordered breathing (SDB) share common pathophysiologic mechanisms. Our objective was to investigate whether children referred for isolated TTI (tympanostomy tube insertion) are at increased risk for snoring and upper airway procedures. Telephone interviews to parents of children who underwent isolated TTI and to age- and gender-matched controls were conducted. Four hundred fifty-seven children were included in the study; 352 had isolated TTI (study group) and 105 children were controls. Twenty-two percent of children in the study group were reported to snore compared with 7.6% in the controls (p=0.001). Eighteen percent of children in the study group were reported to have undergone adenotonsillectomy compared with 4.8% in the controls (p=0.0005). Future SDB, i.e., either snoring or adenotonsillectomy following TTI, was found in 34% of children in the study group compared with 11% in the controls (p=0.0004). Children who underwent isolated TTI were at increased risk for future snoring (OR=3.4, CI: 1.6-7.2) and future adenotonsillectomy (OR=4.4, CI: 1.7-11.2). Children who undergo isolated TTI are at increased risk for snoring and for adenotonsillectomy. We suggest that these children be followed for symptoms of SDB on a scheduled basis to allow for early diagnosis and intervention. 2009 Elsevier B.V. All rights reserved.

Septal deviation is a common disease seen in daily otorhinolaryngology practice and septoplasty is a commonly performed surgical procedure. Caudal septum deviation is also a challenging pathology for ear, nose, and throat specialists. Many techniques are defined for caudal septal deviation. To evaluate the effectiveness of caudal septal extension graft (CSEG) application in patients who underwent endonasal septoplasty for a short and deviated nasal septum. Forty patients with nasal septal deviation, short nasal septum, and weak nasal tip support who underwent endonasal septoplasty with or without CSEG placement between August 2012 and June 2013 were enrolled in this study. Twenty patients underwent endonasal septoplasty with CSEG placement. The rest of the group, who rejected auricular or costal cartilage harvest for CSEG placement, underwent only endonasal septoplasty without any additional intervention. Using the Nasal Obstruction Symptom Evaluation (NOSE) and Rhinoplasty Outcome Evaluation (ROE) questionnaires, pre- and post-operative acoustic rhinometer measurements were evaluated to assess the effect of CESG placement on nasal obstruction. In the control group, preoperative and postoperative minimal cross-sectional areas (MCA1) were 0.44±0.10cm 2 and 0.60±0.11cm 2 , respectively (p<0.001). In the study group, pre- and postoperative MCA1 values were 0.45±0.16cm 2 and 0.67±0.16cm 2 , respectively (p<0.01). In the control group, the nasal cavity volume (VOL1) value was 1.71±0.21mL preoperatively and 1.94±0.17mL postoperatively (p<0.001). In the study group, pre- and postoperative VOL1s were 1.72±0.15mL and 1.97±0.12mL, respectively (p<0.001). Statistical analysis of postoperative MCA1 and VOL1 values in the study and the control groups could not detect any significant intergroup difference (p=0.093 and 0.432, respectively). In the study group, mean nasolabial angles were 78.15±4.26° and 90.70±2.38°, respectively (p<0.001). Endonasal septoplasty with CESG placement is an effective surgical procedure with minimal complication rate for subjects who have a deviated, short nasal septum and weak nasal tip support.

Epidural fibrosis is nonphysiological scar formation, usually at the site of neurosurgical access into the spinal canal, in the intimate vicinity of and around the origin of the radicular sheath. The formation of dense fibrous tissue causes lumbar and radicular pain. In addition to radicular symptoms, the formation of scar tissue may cause problems during reoperation. The authors aimed to investigate the effects of cross-linked high-molecular-weight hyaluronic acid (HA), an HA derivative known as HA gel, on the prevention of epidural fibrosis by using histopathological and biochemical parameters. Fifty-six adult female Sprague-Dawley rats were evaluated. The rats were divided into 4 groups. Rats in the sham group (n = 14) underwent laminectomy and discectomy and received no treatment; rats in the control group (n = 14) underwent laminectomy and discectomy and received 0.9% NaCl treatment in the surgical area; rats in the HA group (n = 14) received HA treatment at the surgical area after laminectomy and discectomy; and rats in the HA gel group (n = 14) underwent laminectomy and discectomy in addition to receiving treatment with cross-linked high-molecular-weight HA in the surgical area. All rats were decapitated after 4 weeks, and the specimens were evaluated histopathologically and biochemically. The results were statistically compared using the Mann-Whitney U-test. Compared with the sham and control groups, the HA and HA gel groups showed significantly lower fibroblast cell density and tissue hydroxyproline concentrations (p < 0.05). There was statistically significant lower dural adhesion and foreign-body reaction between the control and HA gel groups (p < 0.05). Granulation tissue and epidural fibrosis were significantly lower in the HA and HA gel groups compared with the sham group (p < 0.05). There were no significant differences in any histopathological parameters or biochemical values between Groups 3 and 4 (p > 0.05). Cross-linked high-molecular-weight HA had positive effects on the prevention of epidural fibrosis and the reduction of fibrotic tissue density. The efficacy of this agent should also be verified in further experimental and clinical studies.

While the outcomes after Heller myotomy have been extensively reported, little is known about patients with esophageal achalasia who are treated with esophagectomy. This was a retrospective analysis using the Nationwide Inpatient Sample over an 11-year period (2000-2010). Patients admitted with a primary diagnosis of achalasia who underwent esophagectomy (group 1) were compared to patients with esophageal cancer who underwent esophagectomy (group 2) during the same time period. Primary outcome was in-hospital mortality. Secondary outcomes included length of stay, postoperative complications, and total hospital charges. A propensity-matched analysis was conducted comparing the same outcomes between group 1 and well-matched controls in group 2. Nine hundred sixty-three patients with achalasia and 18,003 patients with esophageal cancer underwent esophagectomy. The propensity matched analysis showed a trend toward a higher mortality in group 2 (7.8 vs. 2.9 %, p = 0.08). Postoperative length of stay and complications were similar in both groups. Total hospital charges were higher for the achalasia group ($115,087 vs. $99, 654.2, p = 0.006). This is the largest study to date examining outcomes after esophagectomy in patients with achalasia. Based on our findings, esophagectomy can be considered a safe option, and surgeons should not be hindered by a perceived notion of prohibitive operative risk in this patient population.

The purpose of this study was to evaluate the stability of the Leksell Frame G in Gamma Knife radiosurgery (GKR). Forty patients undergoing GKR underwent pretreatment stereotactic MRI for GKR planning and stereotactic CT immediately after GKR. The stereotactic coordinates of four anatomical landmarks (cochlear apertures and the summits of the anterior post of the superior semicircular canals, bilaterally) were measured by two evaluators on two separate occasions in the pre-treatment MRI and post-treatment CT scans and the absolute distance between the observations is reported. The measurement method was validated with an indepen-dent group of patients who underwent both stereotactic MRI and CT imaging before treatment (negative controls; n: 5). Patients undergoing GKR for arteriovenous malformations (AVM) also underwent digital subtraction angiography (DSA), which could result in extra stresses on the frame. The distance between landmark local-ization in the scans for the negative control group (0.63 mm; 95% CI: 0.57-0.70; SD: 0.29) represents the overall consistency of the evaluation method and provides an estimate of the minimum displacement that could be detected by the study. Two patients in the study group had the fiducial indicator box accidentally misplaced at post-treatment CT scanning. This simulated the scenario of a frame displacement, and these cases were used as positive controls to demonstrate that the evaluation method is capable of detecting a discrepancy between the MRI and CT scans, if there was one. The mean distance between the location of the landmarks in the pretreatment MRI and post-treatment CT scans for the study group was 0.71 mm (95% CI: 0.68-0.74; SD:0.32), which was not statistically different from the over-all uncertainty of the evaluation method observed in the negative control group (p = 0.06). The subgroup of patients with AVM (n: 9), who also underwent DSA, showed a statistically significant difference between the location of the landmarks compared to subjects with no additional imaging: 0.78 mm (95% CI: 0.72-0.84) vs. 0.69 mm (95% CI: 0.66-0.72), p = 0.016. This is however a minimal differ-ence (0.1 mm) and the mean difference in landmark location for each AVM patient remained submillimeter. This study demonstrates submillimeter stability of the Leksell Frame G in GKR throughout the treatment procedure.

The use of opioids among patients with workers' compensation claims is associated with tremendous costs, especially for patients who undergo spinal surgery. This study compared return-to-work rates after single-level cervical fusion for degenerative disk disease between patients who received opioids before surgery and patients who underwent fusion with no previous opioid use. All study subjects qualified for workers' compensation benefits for injuries sustained at work between 1993 and 2011. The study population included 281 subjects who underwent single-level cervical fusion for degenerative disk disease with International Classification of Diseases, Ninth Revision, and Current Procedural Terminology code algorithms. The opioid group included 77 subjects who received opioids preoperatively. The control group included 204 subjects who had surgery with no previous opioid use. The primary outcome was meeting return-to-work criteria within 3 years of follow-up after fusion. Secondary outcome measures after surgery, surgical details, and presurgical characteristics for each cohort also were collected. In 36.4% of the opioid group, return-to-work criteria were met compared with 56.4% of the control group. Patients who took opioids were less likely to meet return-to-work criteria compared with the control group (odds ratio, 0.44; 95% confidence interval, 0.26-0.76; P=.0028). Return-to-work rates within the first year after fusion were 24.7% for the opioid group and 45.6% for the control group (P=.0014). Patients who used opioids were absent from work for 255 more days compared with the control group (P=.0001). The use of opioids for management of diskogenic neck pain, with the possibility of surgical intervention, is a negative predictor of successful return to work after fusion in a workers' compensation population.

To evaluate the protective effects of glutamine in a model of portal hypertension (PH) induced by partial portal vein ligation (PPVL). Male Wistar rats were housed in a controlled environment and were allowed access to food and water ad libitum . Twenty-four male Wistar rats were divided into four experimental groups: (1) control group (SO) - rats underwent exploratory laparotomy; (2) control + glutamine group (SO + G) - rats were subjected to laparotomy and were treated intraperitoneally with glutamine; (3) portal hypertension group (PPVL) - rats were subjected to PPVL; and (4) PPVL + glutamine group (PPVL + G) - rats were treated intraperitoneally with glutamine for seven days. Local injuries were determined by evaluating intestinal segments for oxidative stress using lipid peroxidation and the activities of glutathione peroxidase (GPx), endothelial nitric oxide synthase (eNOS) and inducible nitric oxide synthase (iNOS) after PPVL. Lipid peroxidation of the membrane was increased in the animals subjected to PH ( P < 0.01). However, the group that received glutamine for seven days after the PPVL procedure showed levels of lipid peroxidation similar to those of the control groups ( P > 0.05). The activity of the antioxidant enzyme GTx was decreased in the gut of animals subjected to PH compared with that in the control group of animals not subjected to PH ( P < 0.01). However, the group that received glutamine for seven days after the PPVL showed similar GTx activity to both the control groups not subjected to PH ( P > 0.05). At least 10 random, non-overlapping images of each histological slide with 200 × magnification (44 pixel = 1 μm) were captured. The sum means of all areas, of each group were calculated. The mean areas of eNOS staining for both of the control groups were similar. The PPVL group showed the largest area of staining for eNOS. The PPVL + G group had the second highest amount of staining, but the mean value was much lower than that of the PPVL group ( P < 0.01). For iNOS, the control (SO) and control + G (SO + G) groups showed similar areas of staining. The PPVL group contained the largest area of iNOS staining, followed by the PPVL + G group; however, this area was significantly smaller than that of the group that underwent PH without glutamine ( P < 0.01). Treatment with glutamine prevents gut mucosal injury after PH in rats.

A stroke patient with hemiplegic gait is generally described as being slow and asymmetric. Body weight-supported treadmill training and backward gait training are recent additions to therapeutic gait trainings that may help improve gait in stroke patient with hemiplegic gait. Therefore, we examined the effect of progressive backward body weight-supported treadmill training on gait in chronic stroke patients with hemiplegic gait. Thirty subjects were divided to the experimental and control groups. The experimental group consisted of 15 patients and underwent progressive backward body weight-supported treadmill training. The control group consisted of 15 patients and underwent general treadmill gait training five times per week, for a total of four weeks. The OptoGait was used to analyze gait kinematics, and the dynamic gait index (DGI) and results of the 6-minute walk test were used as the clinical evaluation indicators. A follow-up test was carried out four weeks later to examine persistence of exercise effects. The experimental group showed statistically significant results in all dependent variables week four compared to the control group. However, until the eighth week, only the dependent variables, of affected step length (ASL), stride length (SL), and DGI differed significantly between the two groups. This study verified that progressive bodyweight-supported treadmill training had a positive influence on the temporospatial characteristics of gait and clinical gait evaluation index in chronic stroke patients.

To assess the efficacy and safety of a noncontact, fluid-based capsular polishing technique (hydropolish) to remove residual cortical fibers (RCFs) and epithelial cells from the posterior and equatorial capsule in phacoemulsification cataract surgery. Hydropolish involved manual irrigation of the posterior and equatorial capsule after irrigation/aspiration, using a 27-G hydrodissection cannula. This prospective, consecutive, single surgeon controlled trial was conducted at a dedicated ophthalmic surgery center in Sydney, Australia, between December 20, 2006, and July 14, 2010. Single eyes of consecutive patients underwent cataract surgery without use of hydropolish (control group), while those on or after July 21, 2010, underwent hydropolish (intervention group). Corrected distance visual acuity (CDVA) up to 1 month postoperatively, surgical complications, and hydropolish time were documented. A total of 1531 eyes were included in this study (hydropolish n = 682; control n = 849). After adjusting for age, sex, and nuclear sclerosis grade, no significant difference was found between hydropolish and control groups when preoperative CDVA was compared against postoperative CDVA at 1 day, 1 week, and 1 month (p>0.05). Hydropolish is a rapid and safe technique that can remove RCFs from the posterior and equatorial capsule in phacoemulsification cataract surgery. It does not compromise postoperative CDVA.

The aim was to compare the effects of Twin-block & Forsus (FRD) functional appliances in the correction of Angles Class II division 1 malocclusions. Pre- and post-treatment lateral cephalograms of 25 patients who underwent treatment with twin block for the correction of class II div 1 were compared with 25 patients who underwent treatment with Forsus appliance. These were again compared with the pre follow up and post follow up lateral cephalograms of 25 patients who have not undergone any treatment during this period. All the 3 group patients were compared for skeletal, dental and soft tissue parameters. Cephalometric analysis revealed that both Twin-block & Forsus Fatigue Resistant Device (FRD) appliances stimulated mandibular growth. Statistically significant differences between the two groups were found. Twin-block patients showed statistically very high significant (p < 0.001) increase in mandibular length (6.02 mm) whereas Forsus appliance patients showed significant (p < 0.05) increase in mandibular length (1.6 mm) when compared with control group (0.3 mm). No significant restriction of maxillary growth was found in either of the two experimental groups when compared to control group. Significant increase in lower anterior facial height & posterior facial height was observed in both experimental groups in relation to control group. Significant reduction of overjet and overbite was observed in both experimental groups. Class I molar relationship and improvement in the soft tissue profile were achieved in both treatment groups compared with control group. Both Twin Block and Forsus were effective in the treatment of Class II Div 1 malocclusion. Class II correction with Twin-block is more due to mandibular skeletal and dentoalveolar changes whereas in Forsus, it is more due to dentoalveolar changes and less skeletal changes.

To evaluate the effects of using cryopreserved human amniotic membrane (AM) transplant during strabismus reoperations. A total of 30 patients with persistent strabismus were included in this prospective study. Patients were divided into two groups of 15 patients each. The AM group underwent strabismus reoperation with wrapping of the muscles with cryopreserved amniotic membrane. Controls underwent strabismus reoperation without an AM wrap. Final follow-up visit was scheduled between 3 and 12 months postoperatively. Surgical success was defined as 0 Δ -10 Δ of horizontal tropia and 0 Δ -4 Δ of vertical tropia, with no limitation of ductions exceeding -1. A cosmetically acceptable outcome was defined as a tropia of 0 Δ -15 Δ . Three patients were excluded in the AM group due to incomplete follow-up. A successful outcome was achieved in 7 patients in each group (58% and 47% in groups AM and C, resp.; P = 0.63). A cosmetically acceptable outcome was achieved in 10 patients in the AM group (83.3%) and 12 (80%) in the control group (P = 0.48). The mean ocular deviation angles improved to 8.7 Δ ± 12 Δ in the AM group and 12.3 Δ ± 17.4 Δ in the control group (P = 0.63). Ductions improved in 66.7% and 36.4% of the muscles with limited motility in groups AM and C, respectively (P = 0.019). Wrapping the extraocular muscles with cryopreserved AM during strabismus reoperations was of limited clinical benefit. We attributed this to the small segment of AM used and to the presence of other causes of failure rather than adhesions.

Intrauterine adhesions (IUAs) are the most common complication after hysteroscopy in patients of reproductive age. Intra-abdominal anti-adhesion gel reduces the incidence of adhesions, but effects on fertility after uterine surgery are not known. The objective of our work was to evaluate the effect of intrauterine anti-adhesion gel on spontaneous fertility after repeated intrauterine surgery with induced experimental synechiae in the rabbit model. Twenty New Zealand White rabbits underwent a double uterine curettage 10 days apart and were randomized into two groups. Each rabbit served as its own control: one uterine tube was the treatment group (A), the second uterine tube was the control group (B) to avoid bias through other causes of infertility. Group A received a post curettage intrauterine instillation of anti-adhesion gel whereas group B, the control group, underwent curettage without instillation of the gel. After a recovery period, the rabbits were mated. An abdominal ultrasound performed 21 days after mating allowed us to diagnose pregnancy and quantify the number of viable fetuses. There was a significant difference in total fetuses in favor of group A, with an average of 3.7 (range, 0-9) total fetuses per tube against 2.1 (0-7) in group B (p = .04). The number of viable fetuses shows a trend in favor of group A, with an average of 3.4 (0-7) viable fetuses per tube against 1.9 (0-6) viable fetuses per tube in group B (p = .05). The use of immediate postoperative anti-adhesion gel improved fertility in an animal model after intrauterine surgery likely to cause uterine synechiae. This experimental model will permit comparison of different anti-adhesion solutions, including assessment of their tolerance and potential mucosal toxicity on embryonic development.

This study aimed to compare the body composition, dietary intake and serum levels of vitamins and minerals, and exocrine pancreatic function in patients late after pancreaticoduodenectomy (PD) and healthy subjects. Fifteen patients (PD group) who had undergone PD over 1 year before the study and 15 health volunteers (control group) were included in the study. All volunteers underwent dietary intake evaluation, body composition, laboratory data, exocrine pancreatic function by elastase-1, and carbon (C )-labeled triglycerides in breath tests. The PD group subjects also underwent upper gastrointestinal endoscopy and small intestinal bacterial overgrowth analysis. Nutrient intake was adequate, and there were no differences in body mass index and mineral serum levels between the groups. The PD group showed lower serum levels of retinol, α-tocopherol, and ascorbic acid. Small intestinal bacterial overgrowth occurred in 39% of the patients. Fecal elastase-1 was lower in the PD group. The PD group had a higher C peak time; the cumulative label C recovery in 7 hours was similar in both groups. Fecal elastase-1 decreased, and the excretion of C in breath was similar to healthy controls. Although the data point toward an adaptation in the absorptive capacity of fats, A, C, and E hypovitaminosis indicate that some absorptive insufficiency persists late after PD.

Experiments were conducted on twelve women aged 23-34 yr - a bed rest (BR) group of eight subjects and an ambulatory (AMB) group of four subjects - to determine the effect of bed rest on shifts in plasma volume, electrolytes, and erythrocyte volume during +Gz acceleration on a centrifuge. The BR group underwent the +Gz acceleration during a two-week ambulatory control period, after 15 days of a 17-day BR period, and on the third day of ambulatory recovery. The AMB group underwent the same experimental procedures, but continued their normal daily routine during the BR period without additional prescribed physical exercise. Major conclusions are that (1) the higher the mean control tolerance, the greater the tolerance decline after BR; (2) relative confinement and reduced activity contribute as much to reduction in tolerance as does the horizontal body position during BR; (3) BR deconditioning has no effect on the erythrocyte volume during +3.0 Gz; and (4) about one-half the loss in tolerance after BR can be attributed to plasma volume and electrolyte shifts.

Conduit-based nerve repairs are commonly used for small nerve gaps, whereas primary repair may be performed if there is no tension on nerve endings. We hypothesize that a conduit-based nerve coaptation device will improve nerve repair outcomes by avoiding sutures at the nerve repair site and utilizing the advantages of a conduit-based repair. The left sciatic nerves of female Sprague-Dawley rats were transected and repaired using a novel conduit-based device. The conduit-based device group was compared to a control group of rats that underwent a standard end-to-end microsurgical repair of the sciatic nerve. Animals underwent behavioral assessments at weekly intervals post-operatively using the sciatic functional index (SFI) test. Animals were sacrificed at four weeks to obtain motor axon counts from immunohistochemistry. A sub-group of animals were sacrificed immediately post repair to obtain MRI images. SFI scores were superior in rats which received conduit-based repairs compared to the control group. Motor axon counts distal to the injury in the device group at four weeks were statistically superior to the control group. MRI tractography was used to demonstrate repair of two nerves using the novel conduit device. A conduit-based nerve coaptation device avoids sutures at the nerve repair site and leads to improved outcomes in a rat model. Conduit-based nerve repair devices have the potential to standardize nerve repairs while improving outcomes.

To compare the effects of contralesional sensory cueing and limb activation with that of sham control in the treatment of unilateral neglect after stroke. A randomized, single-blinded, sham-controlled pilot study. Two rehabilitation hospitals. Forty subacute left hemiplegic stroke inpatients with unilateral neglect. Participants were assigned randomly to 1 of 2 groups. The experimental group wore a wristwatch cueing device over the hemiplegic arm for three hours a day, five days per week, for three weeks, and also underwent conventional rehabilitation. Patients were encouraged to move their hemiplegic arm five consecutive times after each prompt. The sham group underwent the same rehabilitation process, except they wore a sham device. Neglect, arm motor performance, and overall functioning were assessed pre- and posttraining, and at follow-up. There were no significant differences between groups in outcome measures except the neglect drawing tasks (p = 0.034) (the mean gain score from baseline to follow-up assessment was 5.2 (3.7) in the experimental group and 1.9 (3.5) in the sham group), across three time intervals. The experimental group showed greater improvement in arm motor performance than did the sham group. The results did not confirm that sensory cueing and limb activation treatment is effective when compared with those receiving placebo to reduce unilateral neglect, but it might be useful for promoting hemiplegic arm performance in stroke patients.

This study reports the clinical outcomes of head and neck adenoid cystic carcinoma treatment over a 20-year period. The treatment outcome of 51 head and neck adenoid cystic carcinoma patients treated between 1992 and 2013 were analysed. Patients were stratified into radical treatment and disease control groups. A total of 40 patients underwent surgery and post-operative radiotherapy. The 10-year disease-specific survival rate was 93 per cent. Eleven patients had tumour recurrence: of these, nine were pulmonary metastases. The 11 patients in the disease control group had a median follow up of 21 months (range, 2-172 months); 5 underwent radical radiotherapy with palliative intent. There was late tumour recurrence in over 25 per cent of patients. Adenoid cystic carcinoma has a high tendency to relapse even after radical excision and adjuvant therapy. However, definitive radiotherapy should still be considered on an individual basis because it may provide local control and prolong patient survival.

Recurrent respiratory papillomatosis (RRP) is a benign epithelial tumor that exhibits a high frequency of recurrence. This study assesses the vocal function after laser treatment for RRP, particularly in relation to the frequency of surgery. Retrospective study. Thirty RRP patients who underwent laser surgery that controlled the tumor were included. Preoperative and postoperative Grade, Roughness, Breathiness, Asthenia, and Strain Scale, videostroboscopic findings, aerodynamic and acoustic parameters, and self-assessment questionnaires were measured and compared with an age- and sex-matched control group. Subsequently, to evaluate the association between postoperative voice quality and the number of surgeries, the patients were divided into three groups (group 1: single surgery, group 2: 2-5 surgeries, group3: >6 surgeries), and comparative multidimensional vocal assessments were performed. The mean number of surgeries was 3.4 (range, 1-8). Although all patients exhibited poorer vocal function than the control group preoperatively, they showed improvement in postoperative subjective and objective parameters. However, four patients who underwent one surgery with relatively aggressive ablation exhibited vocal cord scarring and deteriorated objective parameters. All remaining patients showed voice quality that was on par with the control group. Subgroup analysis proved no association between post-therapeutic voice quality and the patient characteristics, including preoperative staging and the number of surgical treatments performed. RRP patients can achieve a close to normal voice with high satisfaction even after recurrent surgical treatment when ablation of a subepithelial lesion using sufficient laser energy is adequate. 3b Laryngoscope, 127:679-684, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

Malnutrition is associated with an increased risk of mortality and morbidity, longer hospital stays and general loss of quality of life. The aim of this study is to assess the impact of dietary counseling for malnourished hospital patients. Prospective, randomized, open-label study of 106 hospital patients with malnutrition (54 in the control group and 52 in the intervention group). The intervention group received dietary counseling, and the control group underwent standard treatment. We determined the patients' nutritional state (body mass index, laboratory parameters, malnutrition universal screening tool), degree of dependence (Barthel index), quality of life (SF-12), degree of satisfaction (CSQ-8), the number and length of readmissions and mortality. The patients who underwent the "intervention" increased their weight at 6 months, while the controls lost weight (difference in body mass index, 2.14kg/m(2); p<.001). The intervention group had better results when compared with the control group in the Malnutrition Universal Screening Tool scores (difference, -1.29; p<.001), Barthel index (difference, 7.49; p=.025), SF-12 (difference, 13.72; p<.001) and CSQ-8 (difference, 4.34, p<.001) and required fewer readmissions (difference, -0.37; p=.04) and shorter stays for readmissions (difference, -6.75; p=.035). Mortality and laboratory parameters were similar for the 2 groups. Nutritional counseling improved the patients' nutritional state, quality of life and degree of dependence and decreased the number of hospital readmissions.

To investigate the feasibility and effects of balance training with a newly developed Balance Control Trainer (BCT) that applied the concept of vertical movement for the improvements of mobility and balance in chronic stroke patients. Forty chronic stroke patients were randomly assigned to an experimental or a control group. The experimental group (n=20) underwent training with a BCT for 20 minutes a day, 5 days a week for 4 weeks, in addition to concurrent conventional physical therapy. The control group (n=20) underwent only conventional therapy for 4 weeks. All participants were assessed by: the Functional Ambulation Categories (FAC), 10-meter Walking Test (10mWT), Timed Up and Go test (TUG), Berg Balance Scale (BBS), Korean Modified Barthel Index (MBI), and Manual Muscle Test (MMT) before training, and at 2 and 4 weeks of training. There were statistically significant improvements in all parameters except knee extensor power at 2 weeks of treatment, and in all parameters except MBI which showed further statistically significant progress in the experimental group over the next two weeks (p<0.05). Statistically significant improvements on all measurements were observed in the experimental group after 4 weeks total. Comparing the two groups at 2 and 4 weeks of training respectively, 10mWT, TUG, and BBS showed statistically more significant improvements in the experimental group (p<0.05). Balance training with a newly developed BCT is feasible and may be an effective tool to improve balance and gait in ambulatory chronic stroke patients. Furthermore, it may provide additional benefits when used in conjunction with conventional therapies.

To determine the relationship between vaginal reflux (VR) and urinary tract infection (UTI) in female children aged <36 months. A single center retrospective study was performed for 191 girls aged <36 months, with a diagnosis of febrile UTI, who underwent a voiding cystourethrography (VCUG) for assessment of vesicoureteral reflux (VUR) at Sanggye Paik Hospital. Fifty-one girls, who underwent VCUG for assessment of congenital hydronephrosis or renal pelvis dilatation, without a UTI, formed the control group. The correlation between the presence and grade of VR and UTI was evaluated. The prevalence rate of VR was higher in the UTI (42.9%) than control (13.7%) group ( P <0.05), with a higher VR severity grade in the UTI (mean, 0.64) than control (mean, 0.18) group ( P <0.05). On subanalysis with age-matching (UTI group: n=126, age, 5.28±2.13 months; control group: n=22, age, 4.79±2.40 months; P =0.33), both VR prevalence (43.65% vs. 18.18%, P <0.05) and grade (0.65 vs. 0.22, P <0.05) remained higher in the UTI than control group. Presence and higher grade of VR were associated with UTI recurrence ( P <0.05). VR was correlated to urosepsis ( P <0.05). The renal defect rate of patients with VR (VR [+]/VUR [+]) was not different from that of patients without VR (74% vs. 52%, P =0.143) in the VUR group; however, it was higher than that of VR (+)/VUR (-) patients (74% vs. 32%, P =0.001). If a child with VR (+)/VUR (+) is exposed to a UTI, the risk of renal defect increases. Occurrence of VR is associated with UTI recurrence and urosepsis in pediatric female patients.

Introduction: Gonarthrosis is most frequently defined as the change involving damage of the articular cartilage of the knee joint, emergence of abnormal knee tissue, reactive changes in synovial membrane, and pathological synovial fluid. The site of initial damage most often remains unknown. Goal of the research The goal: The goal of this research is to demonstrate the efficacy of individual physical therapy during the medical treatment for gonarthrosis in the working population engaged in physical labour, and to compare the state of pain and mobility before and after the treatment. Subjects and research methods: The research encompassed 30 subjects diagnosed with gonarthrosis, and it was conducted in the Institute of Occupational Health and Sports Medicine of the Zenica-Doboj Canton. On the basis of the applied physical treatments, we divided the subjects into control group and treatment group. All the subjects were treated during 21 days. Results and conclusions: In the largest number of subjects in both groups gonarthrosis occurred primarily as a consequence of knee joint trauma, and then because of weight and physical strain. Of the total number of subjects covered by this research, 9 subjects in control and 8 in treatment group had gonarthrosis of their right knee. 4 subjects in the control and 5 in the treatment group had gonarthrosis of the left knee, while 2 subjects from each group had gonarthrosis on both knees. By the analysis of clinical symptoms of gonarthrosis prior to the treatment, it was found that all the subjects from both groups had pain symptom, in 13 subjects from the control and 14 subjects from the treatment group limited range of motion was established, while 8 subjects from control and 9 subjects from treatment group had swelling in the joint area. The condition of the subjects prior to the treatment was analyzed by means of pain scale, and it was found that both groups experienced moderate level of pain before the treatment. After the 21st day of treatment, the pain intensity was again measured in the subjects that underwent combined physical and medication treatments. In the subjects from the control group that also underwent electrotherapy, the average pain scale value amounted to 2,33±1,34 after treatment, whereas in the subjects that underwent magnetotherapy and combined physical and medication treatments the pain scale amounted to 0,73±0,38. The ANOVA test showed that there is a statistically significant difference in the pain scale before and after the treatment, and also that the improvement in the clinical picture and reduction of pain occurred in both groups of subjects.

Long-term effects of hepatocyte transplantation (HTX) in the treatment of enzyme deficiency disease were studied. Congenic enzyme-deficient (R/APfd-j/j) and non-enzyme-deficient (R/APfd) rats were used as recipients and donors, respectively. The R/APfd-j/j rat strain is congenitally deficient of bilirubin uridyldiphosphate (UDP)-glucuronyl transferase. R/APfd-j/j rats underwent HTX by intrasplenic injection of 10(7) isolated R/APfd hepatocytes (group 1A). Another group of R/APfd-j/j rats was treated similarly, but underwent splenectomy after 11 weeks (group 1B). Controls consisted of R/APfd-j/j rats grafted with 10(7) R/APfd-j/j hepatocytes (group 2), and R/APfd-j/j rats that underwent a sham operation (group 3). Total plasma bilirubin (TB) levels were significantly reduced in groups 1A and 1B during the experiment (both P less than 0.01). In the control groups TB reduction was not observed. Bile analyses at 30 weeks after HTX showed that in group 1A 13.7 +/- 2.7% of total biliary bilirubin was conjugated. In group 1B a significantly lower fraction was conjugated: 6.6 +/- 1.1% (P less than 0.05). Conjugated bilirubin was not found in bile of groups 2 and 3. Histology showed survival of hepatocytes in all spleens of rats of groups 1A, 1B and 2. It is concluded that congenic hepatocytes from R/APfd donors are not rejected after transplantation into the R/APfd-j/j rat, and maintain long-term function. Splenectomy does not abolish, but does reduce, the therapeutic effect significantly, indicating that part of the transplanted hepatocytes maintains function in the enzyme-deficient host liver. The congenic R/APfd-j/j and R/APfd rat strains represent a new animal model for research in metabolic deficiency disease.

The management of patient affected by premature ejaculation (PE) is nowadays not highly satisfactory. Here, we aimed to evaluate the tolerability and efficacy of a combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts in order to improve sexual quality of life in patients with premature ejaculation. All patients attending to 5 urological centers from January 2015 to March 2015, due to premature ejaculation were enrolled in this study. At the enrolment visit, all subjects underwent self-administered IIEF-5, Male Sexual Health Questionnaire-Ejaculation Disorder (MSHQEjD), PEDT and IELTS (calculated as mean from that perceived by partner and that perceived by patient) and underwent urological visit and laboratory examinations. All patients received one tablet per day of a combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts for 3 months (Group A). After 3 months all patients underwent follow-up visit with the same investigations that have been carried out in the enrolment visit. The results were compared with a cohort of patients enrolled in the same period in another urological center and considered as a control group (Group B). All patients in the control group underwent counseling and sexual behavioral treatment without any pharmacological compound. At the follow-up analysis, significant changes in terms of IELT in the Group A (mean difference: 31.90; p < 0.05) at 3 months and versus Group B at the intergroup analysis (mean difference: 30.30; p < 0.05) were reported. In the group A, significant differences from baseline to last follow- up were observed relative to IIEF-5 (mean difference: 1.04; p < 0.05), PEDT (mean difference: -2.57; p < 0.05) and FSH (mean difference: -16.46; p < 0.05). In conclusion, patients affected by PE may significantly benefit from oral therapy with a combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts in terms of IELT and PEDT scores improvement.

Background Laparoscopic surgery has become the standard for treating appendicitis. The cosmetic benefits of using single-incision laparoscopy are well known, but its duration, complications and time to recovery have not been well documented. We compared 2 laparoscopic approaches for treating appendicitis and evaluated postoperative pain, complications and time to full recovery. Methods We retrospectively reviewed the cases of consecutive patients with appendicitis and compared those who underwent conventional laparoscopic appendectomy (CLA) performed using 3 incisions and those who underwent single-incision laparoscopic appendectomy (SILA). During SILA, the single port was prepared to increase visibility of the operative site. Results Our analysis included 688 consecutive patients: 618 who underwent CLA and 70 who underwent SILA. Postsurgical complications occurred more frequently in the CLA than the SILA group (18.1% v. 7.1%, p = 0.018). Patients who underwent SILA returned to oral feeding sooner than those who underwent CLA (median 12 h v. 22 h, p < 0.001). These between-group differences remained significant after controlling for other factors. Direct comparison of only nonperforated cases, which was determined by pathological examination, revealed that SILA was significantly longer than CLA (60 min v. 50 min, p < 0.001). Patients who underwent SILA had longer in-hospital stays than those who underwent CLA (72 v. 55 h, p < 0.001); however, they had significantly fewer complications (3.0% v. 14.4%, p = 0.006). Conclusion In addition to its cosmetic advantages, SILA led to rapid recovery and no increase in postsurgical pain or complications. PMID:24869622

To evaluate the safety, effectiveness, and cost of angiofluoresceinographic examination by using both the least amount of dye as well as digital equipment along with a laser photocopier. Prospective and comparative study carried out in a group of 70 patients, who underwent an angiographic evaluation with a conventional retinographer injecting 5 ml sodium fluorescein at 10% (control group) as well as a group of 70 patients who underwent an angiographic evaluation with a digital retinographer injecting 2 ml fluorescein at 10% (study group). Arterial pressure, heart rate and oximetry were assessed prior to and after the dye injection. Organic reactions related to the examination were reported. Photograph quality as well as cost between the two techniques were compared. Control group patients showed a greater increase in systolic and diastolic arterial pressure. Heart rate, oximetry measurement and adverse reactions did not show any significant statistical differences between both groups. As for the quality of photographs, a better performance was noticed in the control group. As for the cost, the examination carried out in the study group required lower cost and thus saved around 54.8% per examination in relation to the control group. The examination carried out with a lower dose of fluorescein using digital equipment along with a laser photocopier provided greater stability in the systolic and diastolic arterial pressure. However, it did not have any influence on heart rate, oximetry or adverse reactions such as nausea, vomiting, syncope and rashes. The quality of photographs was poor although they enabled diagnosis as well as therapy follow-up for those who carried out the examination. Moreover, economically the above procedure represented a gain of 66.26%, against 25.81% in relation to the conventional equipment.

The association of anaemia with aortic stenosis (AS) has been recognised for over 50 years; however, although there have been several sporadic reports, there are few data on the prevalence of this syndrome. We sought to compare the prevalence of anaemia in adults with AS with that of controls who had undergone coronary artery bypass grafting (CABG). We conducted a retrospective cohort study comparing pre-procedural levels of haemoglobin in 1537 adults who underwent aortic valve replacement (AVR) for AS with 8025 contemporaneous patients who had CABG. We hypothesised that the prevalence of anaemia in patients with AS would be significantly higher than in the control group. A total of 30.1% in the AVR group was anaemic compared to 16.2% in the CABG group. The mean haemoglobin concentration measured across the whole population was significantly lower (132 g/L) in AVR patients than in those who underwent CABG (138 g/L). In a multivariable model, haemoglobin levels varied significantly by treatment group, gender and age. The adjusted marginal mean haemoglobin value was 135.6 g/L in AVR patients compared to 137.3 g/L in CABG patients. The prevalence of anaemia was significantly greater in patients with AS than in a contemporaneous cohort that underwent CABG. This may indicate that Heyde syndrome is more common than has been generally appreciated and should be considered in the evaluation of anaemia in patients with AS. © 2017 Royal Australasian College of Physicians.

The risk of carrying methicillin-resistant Staphylococcus aureus (MRSA) is higher among nursing home (NH) residents than in the general population. However, control strategies are not clearly defined in this setting. In this study, we compared the impact of standard precautions either alone (control) or combined with screening of residents and decolonization of carriers (intervention) to control MRSA in NHs. Cluster randomized controlled trial. NHs of the state of Vaud, Switzerland. Of 157 total NHs in Vaud, 104 (67%) participated in the study. Standard precautions were enforced in all participating NHs, and residents underwent MRSA screening at baseline and 12 months thereafter. All carriers identified in intervention NHs, either at study entry or among newly admitted residents, underwent topical decolonization combined with environmental disinfection, except in cases of MRSA infection, MRSA bacteriuria, or deep skin ulcers. NHs were randomly allocated to a control group (51 NHs, 2,412 residents) or an intervention group (53 NHs, 2,338 residents). Characteristics of NHs and residents were similar in both groups. The mean screening rates were 86% (range, 27%-100%) in control NHs and 87% (20%-100%) in intervention NHs. Prevalence of MRSA carriage averaged 8.9% in both control NHs (range, 0%-43%) and intervention NHs (range, 0%-38%) at baseline, and this rate significantly declined to 6.6% in control NHs and to 5.8% in intervention NHs after 12 months. However, the decline did not differ between groups (P=.66). Universal screening followed by decolonization of carriers did not significantly reduce the prevalence of the MRSA carriage rate at 1 year compared with standard precautions.

We retrospectively evaluated a series of patients who underwent minimally invasive video-assisted thyroidectomy (MIVAT) to define its advantages or disadvantages. Between May 2005 and March 2008, 68 patients underwent MIVAT. Sixty-nine patients who underwent conventional thyroidectomy (CT) during the period before the introduction of the MIVAT technique in our department-chosen with the same inclusion criteria used for MIVAT-served as matched controls. The eligibility criteria for both groups was thyroid nodules < or = 35 mm, thyroid volume < 25 ml, no thyroiditis, and no previous surgery. Forty-five MIVAT and 43 CT patients underwent hemithyroidectomy. Twenty-three MIVAT and 26 CT patients underwent total thyroidectomy. No differences were found in terms of complications, operative time, and radicality of the procedure. Patients who underwent MIVAT experienced significantly less pain, better cosmetic results, and shorter hospital stay than patients who underwent conventional surgery The MIVAT technique, in selected patients, seems to be a valid option for thyroidectomy and even preferable to conventional surgery because of its significant advantages, especially in terms of cosmetic results, postoperative pain, and postoperative recovery.

Pancreatic injury is the most frequent serious morbidity that can occur following laparoscopic splenectomy. The presumed mechanism of injury is direct trauma to the pancreatic tail during hilar dissection or transection with endovascular staplers. It was our aim to study the direct application of topical sealants to a pancreatic injury to prevent a pancreatic leak. A porcine model of pancreatic injury in a normal pancreas was developed. Fourteen animals underwent midline laparotomy and subtotal (8 cm) distal pancreatectomy. The pancreas was sharply divided and minimal cauterization used. A (1/4)-inch round Jackson Pratt drain was secured to the pancreatic stump in all animals. The control group (n = 7) underwent no further treatment. Two groups underwent treatment with a sealant. Group 1 (n = 3) had a hydrogel applied to the pancreatic remnant. Group 2 (n = 4) had a biodegradable sealant of PEG (polyethylene glycol)-collagen formulation applied to the pancreatic stump by aerosol. During the postoperative period, animals were fed 2.2 lb/d of a high fat (10% lard) diet to stimulate pancreatic exocrine function. Total daily drain outputs were recorded, and drain amylase content and serum amylase concentration were measured on postoperative days 3, 7, and 10. A significant pancreatic leak was defined as a drain to serum amylase content of greater than 3:1. Animals were killed on day 10 and explored for undrained fluid collections. The pancreas was removed for histologic evaluation. Control and treatment groups were compared using repeated measures ANOVA of log-transformed data. All animals survived until elective necropsy. In group 1, average total drain outputs were not significantly less than the controls (125 mL versus 269; P = .66). The mean drain/serum amylase concentration on days 3, 7, and 10 were not significantly different between group 1 and the control group. Group 2 had significantly less overall average drainage output than controls (40 mL versus 269 mL; P = .0006). Furthermore, group 2 had a significant reduction in pancreatic leaks on days 3, 7, and 10 as measured by mean drain/serum amylase concentration. No undrained fluid collections were identified at autopsy. Based on our experimental porcine model, a novel collagen-based, biodegradable hydrogel can prevent a ductal leak following pancreatic injury. These encouraging data have fostered application by aerosol treatment to the hilar bed at laparoscopic splenectomy to diminish capsular disruption from mechanical injury.

We aimed to evaluate long-term surgical outcomes in patients treated for mesial temporal lobe epilepsy compared with a similar group of patients who underwent a preoperative evaluation. Patient interviews were conducted by an independent neuropsychologist and included a sociodemographic questionnaire and validated versions of the Beck Depression Inventory-II, Adverse Events Profile, Quality of Life in Epilepsy-31, and Rey Auditory Verbal Learning Test. Seventy-one patients who underwent surgery and 20 who underwent mesial temporal lobe epilepsy preoperative evaluations were interviewed. After an 81-month mean postoperative follow-up, 44% of the surgical patients achieved complete seizure relief according to the Engel classification and 68% according to the International League Against Epilepsy classification. The surgical group had a significantly lower prevalence of depression (P = 0.002) and drug-related adverse effects (P = 0.002). Improvement on unemployment (P = 0.02) was achieved but not on driving or education. Delayed verbal memory recall was impaired in 76% of the surgical and 65% of the control cases (P = 0.32). Regarding the Quality of Life in Epilepsy-31, the operated patients scored higher in their total score (mean, 75.44 vs. mean, 60.08; P < 0.001) and in all but the cognitive functioning domain irrespective of the follow-up length. Seizure control, Beck Depression Score, and Adverse Events Profile severity explained 73% of the variance in the surgical group quality of life. Our study found that, although surgical treatment was effective, its impact on social indicators was modest. Moreover, the self-reported quality of life relied not only on seizure control but also on depressive symptoms and antiepileptic drug burden. Copyright © 2017 The Author(s).

BACKGROUND: Abdominal surgery can lead to postoperative intra-abdominal adhesions (PIAAs) with significant morbidity and mortality. This study compares the use of honey with a standard bioresorbable membrane (Seprafilm™) to prevent the formation of PIAAs in rats. METHODS: Thirty rats underwent laparotomy, and PIAAs were induced by scraping the cecum. The animals were divided into three groups, each containing ten rats. Group 1 (control) represented the cecal abrasion group, with no intraperitoneal administration of any substance. Group 2 (honey group) underwent cecal abrasion and intraperitoneal administration of honey. Group 3 (Seprafilm™ group) underwent cecal abrasion and intraperitoneal Seprafilm™ application. RESULTS: Group 1 exhibited higher adhesion scores for adhesions between the abdominal wall and the organs. Groups 2 and 3 had decreased adhesive attachments to the intra-abdominal structures. Compared to group 1, the incidence of adhesion formation was lower in both group 2 (p=0.001) and group 3 (p=0.001). The incidence of fibrosis was also lower in group 2 (p=0.016) and group 3 (p=0.063) compared to group 1. There was no significant difference between the histopathological fibrosis scores for the rats in group 2 and those in group 3 (p= 0.688). CONCLUSION: This study suggests that both honey and Seprafilm™ decrease the incidence of PIAAs in the rat cecal abrasion model. Although the mechanism of action is not clear, intraperitoneal administration of honey reduced PIAAs. The outcome of this study demonstrates that honey is as effective as Seprafilm™ in preventing PIAAs. PMID:19488596

To investigate the role of estrogen in the formation and development of abdominal aortic aneurysm (AAA). Twenty male Wistar rats were randomly divided into 2 equal groups: experiment group, injected with 17-beta estradiol (E2) intraperitoneally 1 week before the establishment of AAA once a day for 3 weeks (until 2 weeks after the establishment of AAA), and underwent infusion of pancreatic elastase into the infrarenal abdominal aorta through a catheter inserted into the left common iliac artery o as to establish the AAA model, and control group, injected with normal saline intraperitoneally for 3 weeks. Two weeks after the establishment of AAA model, the rats underwent laparotomy, blood samples were collected from vena cava inferior to detect the level of E2 by radioimmunoassay and then the aneurysms were harvested to undergo immunohistochemistry and real-time PCR to detect the protein expression and mRNA expression of matrix metalloproteinase (MMP)-2 and MMP-9. The plasma E2 level of the experiment group was (28+/-6) pg/ml, significantly higher than that of the control group [(5.86+/-0.24) pg/ml, P<0.01]. The aorta dilatation rate of the experiment group was (103+/-4)%, significantly lower than that of the control group [(172+/-13)%, P<0.01]. The destruction of arterial wall, degradation of elastic fibers, and infiltration of inflammatory cells were all more severe in the control group than in the experiment group. The relative mRNA expression of MMP-2 of the experiment group was 0.07+/-0.04, significantly lower than that of the control group (0.22+/-0.07, P<0.01); and the relative mRNA expression of MMP-9 of the experiment group was 1.4+/-0.7, significantly lower than that of the control group (7.4+/-2.8, P<0.01). The protein expression of MMP-2 of the experiment group was (22+/-3)%, significantly lower than that of the control group [(50+/-12)%, P<0.01], and the protein expression of MMP-9 of the experiment group was (23+/-2)%, significantly lower than that of the control group too [(45+/-10)%, P<0.01]. Estrogen inhibits the AAA formation and development by reducing the MMP-2 and MMP-9 mRNA and protein expression and the infiltration of inflammatory cells.

Total hip and knee replacment surgeries are characterized by severe postoperative pain. Local infiltration analgesia is proved to be very effective. However this method has not been widely used in Hungary. To evaluate the efficacy of the local infiltration analgesia with modified components in patients underwent total hip or knee replacement surgery. Data of 99 consecutive patients underwent primary total hip or knee replacement surgery were evaluated prospectively. In all the 99 surgeries modified local infiltration analgesia was applied. Postoperative pain reported on a visual analog scale was recorded as well as the need for further analgetics during the first 18 hours after surgery. The cost of the analgetic drugs was calculated. The control group comprised 97 consecutive patients underwent total hip or knee replacement, where local infiltration analgesia was not applied. Statistical analysis was done. Patients received local infiltration analgesia reported significantly less pain (p<0.001). The need for postoperatively given analgetics was almost 50% less, and the cost of all postoperative analgetics was 47% less than in the control group. In total hip and knee replacement surgeries the modified local infiltration analgesia decreases postoperative pain effectively and contribute to the early mobilization of the patients. Orv.

To inform the morbidity and mortality observed in cirrhotic patients who underwent open cholecystectomy. We reviewed the clinical records of 31 cirrhotics that underwent open cholecystectomy and they were compared with a control group of the same age and sex. Despite administration of plasma or vitamin K or both, bleeding and transfusions during surgery were observed more frequently in cirrhotics. The morbidity was 13% in the controls and 42% in the cases. Renal failure, cardiac failure and upper gastrointestinal bleeding were present only in the cirrhotics. Mortality was 16% in this group (one Child A patient and four Child B-C patients). The variable related with major morbimortality was Child B or C classification. Open cholecystectomy was associated with high morbimortality. The valoration and preparation before surgery must be careful, and the indication from this procedure needs to be made with caution.

To evaluate the effect of a group-based multidisciplinary rehabilitation programme on disability, pain and quality of life in subjects with chronic neck pain. Randomized controlled trial. Specialized rehabilitation centre. A total of 170 patients (mean age of 53 years (13); 121 females). The multidisciplinary group underwent a multidisciplinary rehabilitation programme combining multimodal exercises with psychologist-lead cognitive-behavioural therapy sessions. The general exercise group underwent general physiotherapy. Both groups followed group-based programmes once a week for ten weeks. Additionally, the multidisciplinary group met with the psychologist once a week for a 60-minute session. The Neck Disability Index (primary outcome), the Tampa Scale for Kinesiophobia, the Pain Catastrophizing Scale, a pain numerical rating scale and the Short-Form Health Survey. The participants were evaluated before, after training and after 12 months. A linear mixed model for repeated measures was used for each outcome measure. Significant effects ( p-value <0.001) were found over time and between groups for all outcome measures. After training, significant improvements were found for both groups for all outcome measures except kinesiophobia and catastrophizing, which did not change in the control group; however, the improvements were significantly greater for the multidisciplinary group. At 12-month follow-up a clinically meaningful between-group difference of 12.4 Neck Disability Index points was found for disability. A group-based multidisciplinary rehabilitation programme including cognitive-behavioural therapy was superior to group-based general physiotherapy in improving disability, pain and quality of life of subjects with chronic neck pain. The effects lasted for at least one year.

To evaluate whether dogs undergoing splenectomy had an increased risk of gastric dilatation-volvulus (GDV), compared with a control group of dogs undergoing enterotomy. Retrospective case-control study. 219 dogs that underwent splenectomy for reasons other than splenic torsion (splenectomy group; n = 172) or enterotomy (control group; 47) without concurrent gastropexy. Medical records were reviewed for information on signalment, date of surgery, durations of surgery and anesthesia, reason for splenectomy, histopathologic findings (if applicable), whether gastropexy was performed, duration of follow-up, and date of death (if applicable). Follow-up information, including occurrence of GDV, was obtained via medical records review and a written client questionnaire. Reasons for splenectomy included splenic neoplasia, nonneoplastic masses, infarction, traumatic injury, and adhesions to a gossypiboma. Incidence of GDV following surgery was not significantly different between dogs of the splenectomy (14/172 [8.1 %]) and control (3/47 [6.4%]) groups. Median time to GDV for the 17 affected dogs was 352 days (range, 12 to 2,368 days) after surgery. Among dogs that underwent splenectomy, sexually intact males had a significantly higher incidence of GDV (4/16) than did castrated males and sexually intact or spayed females (10/156). Incidence of GDV among sexually intact male dogs did not differ between groups. Results did not support a recommendation for routine use of prophylactic gastropexy in dogs at the time of splenectomy. Other patient-specific risk factors should be assessed prior to recommending this procedure.

Testicular cellular toxicity of cadmium : transmission electron microscopy examination.

It is clear that environmental heavy metals influence life systems and reproductive system. In the present study histological investigation revealed that cadmium was testicular toxicant in mice. Here we compared the fine-structure of spermatogenesis in two groups of mice (SWR), experimental and control. The experimental group underwent cadmium ingestion at 1 mg/kg daily for 4 weeks. The control group underwent ingestion of distilled water with equal dosages, using the same type of injectors, for 4-weeks. After cadmium exposure period both control and experimental groups were killed and samples of the testes were processed for microscopic examination. Ultra sections were examined and photographed by Transmission Electron Microscope (JEOL- 100SX) at 80KV. Ultrastructure examination revealed, vascular endothelial, interstitial, and sertoli cells damages. Early impairments of germinal cellular differentiation resulted in deformations in all parts of late spermatid. There were dislocation of accrosomal granules, nuclear damage associated with chromatin heterogeneity, detached spermatid from the apical process of sertoli cell, disarrangement of the mitochondria, abnormal oriented tail piece, and abnormal microtubules complex. These ultra morphological abnormalities relate to cell injury and to the resulting physiological abnormality, necrobiosis. Based on the results of this investigation it can be concluded that cadmium ingestion at 1000 microg/kg caused testicular toxicity and abnormalities in early sperm development.

While the efficacy of mental visual imagery (MVI) to alleviate autobiographical memory (AM) impairment in multiple sclerosis (MS) patients has been documented, nothing is known about the brain changes sustaining that improvement. To explore this issue, 20 relapsing-remitting MS patients showing AM impairment were randomly assigned to two groups, experimental (n = 10), who underwent the MVI programme, and control (n = 10), who followed a sham verbal programme. Besides the stringent AM assessment, the patients underwent structural and functional MRI sessions, consisting in retrieving personal memories, within a pre-/post-facilitation study design. Only the experimental group showed a significant AM improvement in post-facilitation, accompanied by changes in brain activation (medial and lateral frontal regions), functional connectivity (posterior brain regions), and grey matter volume (parahippocampal gyrus). Minor activations and functional connectivity changes were observed in the control group. The MVI programme improved AM in MS patients leading to functional and structural changes reflecting (1) an increase reliance on brain regions sustaining a self-referential process; (2) a decrease of those reflecting an effortful research process; and (3) better use of neural resources in brain regions sustaining MVI. Functional changes reported in the control group likely reflected ineffective attempts to use the sham strategy in AM.

The purpose of this study was to investigate whether transcatheter renal sympathetic denervation (RSD) interfere with the development of left ventricular (LV) mechanical dyssynchrony during the progression of heart failure (HF). Nineteen beagles were randomly divided into sham-operated group (six dogs), control group (seven dogs), and RSD group (six dogs). Sham-operated group were implanted with pacemakers without pacing; Control group were implanted with pacemakers and underwent 3 weeks of rapid right ventricular pacing; and RSD group underwent catheter-based RSD bilaterally and were simultaneously implanted with pacemakers. Both LV strain and LV dyssynchrony were analyzed via 2D speckle-tracking strain echocardiography to evaluate LV function. Longitudinal dyssynchrony was determined as the standard deviation for time-to-peak speckle-tracking strain on apical 4- and 2-chamber views. Radial and circumferential dyssynchrony was determined as the standard deviation for time-to-peak speckle-tracking strain in mid- and base-LV short-axis views. Each myocardial function was also evaluated by averaging the peak systolic strains. LV systolic pressure (LVSP) and LV end-diastolic pressure (LVEDP) were measured. The LV interstitial fibrosis was determined by histological analysis. Plasma angiotensin II (Ang II), aldosterone and norepinephrine (NE) levels were also measured. After 3 weeks, all of the dogs in both the control and RSD groups showed greater LV end-diastolic volume compared with the sham-operated group; however, the dogs in the RSD group had a higher LV ejection fraction (LVEF) than the dogs in the control group (p<0.001). The LV systolic strains were higher in the RSD group than in the control group (p<0.001 for longitudinal, circumferential and radial strain, respectively). The levels of LV dyssynchrony were lower in the RSD group than in the control group (p<0.001 for longitudinal, circumferential and radial dyssynchrony, respectively). Compared with dogs with control alone, RSD dogs had lower LV end-diastolic pressures and less fibrous tissue. The levels of plasma Ang II, aldosterone and NE were lower in the RSD group than in the control group. RSD inhibites the development of left ventricular mechanical dyssynchrony during the progression of heart failure in dogs.

To document perinatal outcomes following use of the 'Solomon technique' in the selective photocoagulation of placental anastomoses for severe twin-twin transfusion syndrome (TTTS). Between January 2010 and July 2012, data were collected from 102 consecutive monochorionic twin pregnancies complicated by severe TTTS that underwent fetoscopic laser ablation at four different centers. We compared outcomes between subjects that underwent selective laser coagulation using the Solomon technique (cases) and those that underwent selective laser coagulation without this procedure (controls). Of the 102 pregnancies examined, 26 (25.5%) underwent the Solomon technique and 76 (74.5%) did not. Of the 204 fetuses, 139 (68.1%) survived up to 30 days of age. At least one twin survived in 82 (80.4%) pregnancies and both twins survived in 57 (55.9%) pregnancies. When compared with the control group, the Solomon-technique group had a significantly higher survival rate for both twins (84.6 vs 46.1%; P < 0.01) and a higher overall neonatal survival rate (45/52 (86.5%) vs 94/152 (61.8%); P < 0.01). Use of the Solomon technique remained independently associated with dual twin survival (adjusted odds ratio (aOR), 11.35 (95% CI, 3.11-53.14); P = 0.0007) and overall neonatal survival rate (aOR, 4.65 (95% CI, 1.59-13.62); P = 0.005) on multivariable analysis. There were no cases of recurrent TTTS or twin anemia-polycythemia sequence (TAPS) in the Solomon-technique group. Use of the Solomon technique following selective laser coagulation of placental anastomoses appears to improve twin survival and may reduce the risk of recurrent TTTS and TAPS. Our data support the idea of performing a randomized controlled trial to evaluate the effectiveness of the Solomon technique. Copyright © 2013 ISUOG. Published by John Wiley & Sons Ltd.

The main aim was to assess the effects of a spa treatment on the resumption of occupational and non-occupational activities and the abilities of women in breast cancer remission. A cost-effectiveness analysis (CEA) was also performed. A multicentre randomised controlled trial was carried out between 2008 and 2010 in the University Hospital of Auvergne and two private hospitals in Clermont-Ferrand, France. Eligible patients were women in complete breast cancer remission without contraindication for physical activities or cognitive disorders and a body mass index between 18.5 and 40 kg/m(2). The intervention group underwent spa treatment combined with consultation with dietician whereas the control underwent consultations with the dietician only. Of the 181 patients randomised, 92 and 89 were included in the intervention and the control groups, respectively. The CEA involved 90 patients, 42 from the intervention group and 48 from the control group. The main results showed a higher rate of resumption of occupational activities in the intervention group (p = 0.0025) and a positive effect of the intervention on the women's ability to perform occupational activities 12 months after the beginning of the study (p = 0.0014), and on their ability to perform family activities (p = 0.033). The stay in a thermal centre was cost-effective at 12 months. Spa treatment is a cost-effective strategy to improve resumption of occupational and non-occupational activities and the abilities of women in breast cancer remission. Copyright © 2014 Elsevier Ltd.

Paraplegia is one of the most severe complications occurring after the repair of thoracic and thoracoabdominal aortic aneurysms. Remote ischemic preconditioning (RIPC) has been shown to mitigate neurologic damage, and this study assessed its efficacy in preventing spinal cord ischemia. The study randomized 16 female pigs into an RIPC group (n = 8) and a control group (n = 8). The RIPC group underwent four cycles of 5-minute ischemia-reperfusion episodes by intermittent occlusion of the left iliac artery. All animals underwent systematic closure of the left subclavian artery and segmental arteries of the descending thoracic aorta to the level of diaphragm. Motor-evoked potential monitoring was performed in both hind limbs. Continuous electrocardiogram and hemodynamics were monitored, and pulmonary artery blood samples were collected. A neurologic assessment was performed 6 hours after the procedure. The thoracic and lumbar portions of the spinal cord were collected for histologic and immunohistochemical analysis. The bilateral motor-evoked potential amplitude responses were higher in the RIPC group (p < 0.05) than in the control group; the difference was detected already before spinal cord ischemia. Paraplegia occurred in 1 control animal. Immunohistochemical total scores of antioxidant response regulator nuclear factor erythroid 2-related factor 2 were better in the RIPC group (11.0; range, 8.5 to 14.0) than in the control group (5.2; range, 1.0 to 9.0; p = 0.023). RIPC induces electrophysiologic changes in the central nervous system that may confer spinal cord protection extending the resistance to ischemia. The significantly higher nuclear factor erythroid 2-related factor 2 scores suggest better neuronal cell protection against oxidative stress in the RIPC group.

Contact immunotherapy with squaric acid dibutylester (SADBE) for cutaneous warts has been reported to be effective, although no controlled studies are available so far. The aim of this study was to evaluate the efficacy of SADBE on cutaneous warts by a randomized, double-blind, vehicle-controlled, clinical trial. Thirty-six patients were randomly assigned to SADBE (18 cases) or vehicle (18 cases) group. At 8 weeks, subjects were clinically evaluated for number/size reduction rate and for Investigator Global Assessment. Those who showed improvement extended therapy up to 40 weeks, whereas those who showed unresponsiveness were either switched to SADBE application for up to 48 weeks (if in the vehicle group) or withdrawn from the study (if under SADBE). At 8 weeks, a significant reduction in wart number (P = 0.020) and size (P = 0.010) in the SADBE group, with clearing rates of 41.2% versus 12.5% in the SADBE and vehicle groups, respectively, was observed. Nine remaining SADBE responders who underwent treatment extension up to 40 weeks achieved clearing versus 2 patients of the vehicle group who remained unresponsive. Clearing was obtained in 81.8% of patients who underwent previous ineffective vehicle treatment and had been switched to SADBE. Squaric acid dibutylester is an effective therapeutic option and is significantly more effective than vehicle.

To evaluate the efficacy of acupuncture in the treatment of fibromyalgia, considering the immediate response of the visual analogue pain scale (VAS) as its primary outcome. Randomized, controlled, double-blind study including 36 patients with fibromyalgia (ACR 1990) selected from the outpatient rheumatology clinic, Santa Casa de Misericórdia, Ponta Grossa, PR. Twenty-one patients underwent an acupuncture session, under the principles of the traditional Chinese medicine, and 15 patients underwent a placebo procedure (sham acupuncture). For pain assessment, the subjects completed a Visual Analogue Scale (VAS) before and immediately after the proposed procedure. The mean change in VAS was compared among groups. The variation between the final and initial VAS values was -4.36±3.23 (P=0.0001) in the treatment group and -1.70±1.55 in the control group (P=0.06). The difference in terms of amplitude of variation of VAS (initial - final VAS) among groups favored the actual procedure (P=0.005). The effect size (ES) for the treatment group was d=1.7, which is considered a large effect. Although small, the statistical power of the sample for these results was very relevant (94.8%). Acupuncture has proven effective in the immediate pain reduction in patients with fibromyalgia, with a quite significant effect size. Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

To compare in a prospective, randomized trial the long-term results of laparoscopic Heller myotomy plus Dor fundoplication versus laparoscopic Heller myotomy plus floppy-Nissen for achalasia. Anterior fundoplication is usually performed after Heller myotomy to control GER; however, the incidence of postoperative GER ranges between 10% and 30%. Total fundoplication may aid in reducing GER rates. From December 1993 to September 2002, 153 patients with achalasia underwent Heller laparoscopic myotomy plus antireflux fundoplication. Of these, 9 were excluded from the study. The remaining 144 patients were randomly assigned to 2 treatment groups: Heller laparoscopic myotomy plus anterior fundoplication (Dor procedure) or Heller laparoscopic myotomy plus total fundoplication (floppy-Nissen procedure). The primary end point was incidence of clinical and instrumental GER after a minimum of 60 months follow-up. The secondary end point was recurrence of dysphagia. Follow-up clinical assessments were performed at 1, 3, 12, and 60 months using a modified DeMeester Symptom Scoring System (MDSS). Esophageal manometry and 24-hour pH monitoring were performed at 3, 12, and 60 months postoperative. Of the 144 patients originally included in the study, 138 were available for long-term analysis: 71 (51%) underwent antireflux fundoplication plus a Dor procedure (H + D group) and 67 (49%) antireflux fundoplication plus a Nissen procedure (H + N group). No mortality was observed. The mean follow-up period was 125 months. No statistically significant differences in clinical (5.6% vs. 0%) or instrumental GER (2.8% vs. 0%) were found between the 2 groups; however, a statistically significant difference in dysphagia rates was noted (2.8% vs. 15%; P < 0.001). Although both techniques achieved long-term GER control, the recurrence rate of dysphagia was significantly higher among the patients who underwent Nissen fundoplication. This evidence supports the use of Dor fundoplication as the preferred method to re-establish GER control in patients undergoing laparoscopic Heller myotomy.

To evaluate ambulatory function and leg muscle thickness after whole body vibration training in children with cerebral palsy. A block randomized controlled trial with two groups. Physical therapy department laboratory. A total of 30 (15 experimental, mean (SD) age 10.0 (2.26) years and 15 control, 9.6 (2.58)) children with cerebral palsy, 15 males and 15 females. The experimental group underwent whole body vibration training combined with conventional physical therapy training; the control group underwent conventional physical therapy training three days a week for eight weeks respectively. Three-dimensional gait analyses and ultrasonographic imaging of the leg muscles were measured at pre- and post-test of intervention for eight weeks. Whole body vibration training resulted in significantly better gait speed (P = 0.001, from 0.37 (0.04) m/s to 0.48 (0.06)), stride length (P = 0.001, from 0.38 (0.18) m to 0.48 (0.18)) and cycle time (P = 0.001, from 0.85 (0.48) s to 0.58 (0.38)) in the experimental group compared with that in the control group. The ankle angle (P = 0.019, from 7.30 (4.02) degree to 13.58 (8.79)) also showed a remarkable increase in the experimental group, but not the hip (P = 0.321) and knee angle (P = 0.102). The thicknesses of the tibialis anterior (P = 0.001, 0.48 (0.08) mm to 0.63 (0.10)) and soleus (P = 0.001, 0.45 (0.04) mm to 0.63 (0.12)) muscles were significantly higher in the experimental group than in the control group. However, no significant effect was observed in the thickness of the gastrocnemius muscle (P = 0.645). These findings suggest that whole body vibration may improve mobility in children with cerebral palsy, probably through a positive effect on the leg muscles.

This study compared long-term speech performance after cochlear implantation (CI) between surgical strategies in patients with chronic otitis media (COM). Thirty patients with available open-set sentence scores measured more than 2 yr postoperatively were included: 17 who received one-stage surgeries (One-stage group), and the other 13 underwent two-stage surgeries (Two-stage group). Preoperative inflammatory status, intraoperative procedures, postoperative outcomes were compared. Among 17 patients in One-stage group, 12 underwent CI accompanied with the eradication of inflammation; CI without eradicating inflammation was performed on 3 patients; 2 underwent CIs via the transcanal approach. Thirteen patients in Two-stage group received the complete eradication of inflammation as first-stage surgery, and CI was performed as second-stage surgery after a mean interval of 8.2 months. Additional control of inflammation was performed in 2 patients at second-stage surgery for cavity problem and cholesteatoma, respectively. There were 2 cases of electrode exposure as postoperative complication in the two-stage group; new electrode arrays were inserted and covered by local flaps. The open-set sentence scores of Two-stage group were not significantly higher than those of One-stage group at 1, 2, 3, and 5 yr postoperatively. Postoperative long-term speech performance is equivalent when either of two surgical strategies is used to treat appropriately selected candidates.

The objective of the present work was to study peculiarities of the analgesic action of therapeutic electrical stimulation (TES therapy) in the early postoperative period in the patients who underwent tonsillectomy. A total of 60 patients admitted for this surgery to the specialized otorhinolaryngological department were available for observation. They were divided into two groups depending on the pain relief strategy. The patients of the study group (n=30) underwent courses of transcranial electrical stimulation on a daily basis (from the onset of hospitalization) in addition to the administration of a standard analgetic. The standard dose of tramadol (2.0 ml) was given to the patients of the control group (n=30) who complained of strong pain. The results of the objective and subjective estimations indicate that the degree of pharyngeal pain in the patients treated with TES therapy and the standard analgetic was significantly different. The patients receiving TES therapy could sooner resume their habitual diet and required smaller amounts of the analgetic which makes this modality a cost-effective supplement to the standard postoperative treatment.

Our laboratory has demonstrated that significantly more cell-mediated immunosuppression occurs after full laparotomy than after either anesthesia control or carbon dioxide (CO2) pneumoperitoneum. We further demonstrated that the postoperative immunosuppression is related to the length of the incision. Other investigators believe that the immunosuppression observed after laparotomy is caused by peritoneal exposure to small amounts of lipopolysaccharide found in circulating air. They believe that the better-preserved immune function associated with laparoscopic surgery results from the avoidance of air contamination of the peritoneal cavity. To investigate this hypothesis, we determined and compared postoperative lymphocyte proliferation rates after (a) laparotomy in room air, (b) laparotomy in a CO2 chamber, (c) CO2 insufflation in a murine model, and (d) anesthesia alone. Female C3H/He mice (n = 21) were divided randomly into four groups: (a) anesthesia control, (b) air laparotomy, (c) CO2 laparotomy, and (d) CO2 insufflation. The control mice underwent no procedure. The group 2 animals underwent a full midline incision (xiphoid to pubis) and exposure to room air for 20 min and then were clipped closed. The group 3 mice underwent a full midline incision in a sealed CO2 chamber for 20 min, and the group 4 mice insufflation with CO2 gas at 4 to 6 mm Hg for 20 min. Splenocytes were harvested from all the animals on day 2 after the interventions. Lymphocyte proliferation then was assessed using the nonradioactive colorimetric MTS/PMS system 72 h after concanavalin-A stimulation. There was no significant difference in lymphocyte proliferation between the air and CO2 laparotomy groups. Lymphocyte proliferation in the anesthesia control and CO2 insufflation groups was significantly higher than in both the air laparotomy (p<0.05) and CO2 laparotomy (p<0.05) groups (p values by Tukey-Kramer test). There was no significant difference between the anesthesia control and CO2 pneumoperitoneum groups. Our results suggest that full laparotomy performed in a sealed CO2 chamber compared to room air laparotomy resulted in similar suppression of lymphocyte proliferation. Furthermore, no significant suppression of lymphocyte proliferation was observed in the CO2 pneumoperitoneum group. These results, with regard to lymphocyte proliferation rates, refute the hypothesis that postoperative immunosuppression is related to air exposure and support the alternative hypothesis that immunosuppression is related to incision length.

Anastomotic leaks after colorectal operation continue to be a significant cause of morbidity. A covered endoluminal stent could seal a leak and eliminate the need for diversion. The aim of this study was to test the efficacy of a temporary covered stent to prevent leak related complications. Sixteen adult pigs (80-120 lbs) underwent open transection of the rectosigmoid followed by anastomosis with a circular stapler. Eight animals (study group) underwent endoscopic placement of a 21-mm covered polyester stent. Eight control group animals were left without stents. In all animals, a 2-cm leak was created along the anterior portion of the anastomosis. The animals were killed after 2 weeks and evaluated for abdominal infection, fistulae, and adhesions. The anastomosis was excised and the following parameters were assessed by a pathologist blinded to treatment: mucosal interruption (mm), inflammatory response, collagen type I and III, granulation, and fibrosis (grade 0-4). Stents were spontaneously expelled between postoperative days 6 and 9. At necropsy, none of the animals in the study group had leak related complications, whereas in the control group, 5 (63%) developed intraabdominal infection (4 abscesses, 1 fistula) at the anastomosis (P = .002). Dense adhesions to the anastomosis were found in 7 (88%) control animals. On histology, anastomotic sites in the study group had significantly less mucosal interruption and granulation. Two pigs in the study group died on postoperative day 7, one due to evisceration and one from bladder necrosis. The mortality result is not different from controls (P = .47), both events seem to be unrelated to stent placement. Temporary placement of a covered polyester stent across a colorectal anastomosis prevents leak-related complications and supports the healing of anastomotic leaks.

Background: Tibial plateau fractures account for a small portion of all fractures; however, these fractures can pose a surgical challenge when occurring concomitantly with ligament injuries. Purpose/Hypothesis: The purpose of this study was to compare 2-year outcomes of soft tissue reconstruction with or without a concomitant tibial plateau fracture and open reduction internal fixation. We hypothesized that patients with a concomitant tibial plateau fracture at the time of soft tissue surgery would have inferior outcomes compared with patients without an associated tibial plateau fracture. Study Design: Cohort study; Level of evidence, 3. Methods: Forty patients were included in this study: 8 in the fracture group and 32 in the matched control group. Inclusion criteria for the fracture group included patients who were at least 18 years old at the time of surgery and sustained a tibial plateau fracture and a concomitant injury of the anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament, or fibular collateral ligament in isolation or any combination of cruciate or collateral ligaments and who subsequently underwent isolated or combined ligament reconstruction. Patients were excluded if they underwent prior ipsilateral knee surgery, sustained additional bony injuries, or sustained an isolated extra-articular ligament injury at the time of injury. Each patient with a fracture was matched with 4 patients from a control group who had no evidence of a tibial plateau fracture but underwent the same soft tissue reconstruction procedure. Results: Patients in the fracture group improved significantly from preoperatively to postoperatively with respect to Short Form–12 (P < .05) and Western Ontario and McMaster Universities Osteoarthritis Index total scores (P < .05). The Lysholm (P = .075) and Tegner scores (P = .086) also improved, although this was not statistically significant. Patients in the control group improved significantly from preoperatively to postoperatively across all measured scores. A comparison of the postoperative results between the 2 groups showed no statistically significant difference. Conclusion: The presence of a tibial plateau fracture in conjunction with a ligamentous knee injury did not have a negative effect on postoperative patient-reported outcomes. Patient-reported outcome scores after surgery in both the fracture and control groups improved beyond the minimally clinically important difference, indicating that the presence of a fracture did not detract from the outcomes observed in patients without fractures undergoing concomitant ligament reconstruction.

The aim of this preliminary study was to investigate the clinical use of acute-stage susceptibility-weighted imaging (SWI) in children with prolonged convulsive disorder. Ten children with prolonged convulsive disorder who underwent SWI within 2 h after termination of seizure (acute-stage SWI group) and 15 control children who underwent SWI > 2 h after their seizures terminated or for other purposes were enrolled. The cerebral venous vasculature was compared between the groups. The acute-stage SWI group was further divided into three subgroups: normal group, those with regional low signals in the cerebral veins (regional group) and those with diffuse low signals in the cerebral veins (generalized group). Inter-ictal electroencephalography (EEG) and venous blood gas findings during seizure activity were compared between these subgroups. All patients in the acute-stage SWI group had low cerebral vein signal. Four patients were assigned to the regional group and six patients to the generalized group. Decrease of venous pH and the increase of venous pCO2 during seizure activity was more prominent in the regional group than in the generalized group. In the regional group, low-signal areas in the cerebral veins were consistent with abnormal areas on EEG; these low-signal areas resolved completely in all patients on follow-up SWI. Ten patients in the control group had normal SWI, and five had a generalized low signal. Acute-stage SWI may be a useful alternative for identifying lateralization of seizures in children with prolonged convulsive disorder. © 2015 Japan Pediatric Society.

The purpose of the study was to investigate results of selective laser trabeculoplasty (SLT) performed directly on the sclera without a gonioscopy lens. Interventional case series, prospective, randomized, masked, controlled clinical trial. Setting: Meir Medical Center, Kfar-Saba, Israel. Adults with uncontrolled primary open angle or pseudoexfoliation glaucoma randomized into 2 groups. The controls underwent conventional SLT with 100 spots delivered using a gonioscopy lens for 360 degrees of the trabecular meshwork. The study group underwent irradiation using the same parameters with the laser applications administered on the perilimbal sclera. Study visits: 1 hour, 1, 7, 30, 60, 180, and 365 days postprocedure. Intraocular pressure (IOP) and side effects. Thirty adults were randomized into 2 groups. The mean (±SD) pretreatment IOP was 20.21±3.19 mm Hg for the study group (n=14) and 21.14±2.98 mm Hg for the controls (n=14; P =0.43), dropping to 15.50±3.77 and 15.00±4.08 mm Hg (P =0.74) after 6 months and to 16.00±3.31 and 14.00±2.45 mm Hg (P =0.22) after 12 months. The average IOP reduction after 6 and 12 months was 23.4% and 20.83% for the study group and 27.1% and 33.77% for the controls (P=0.528). Success (a decrease of ≥15% at 6 months with no additional medications, laser, or glaucoma surgery) was achieved in 12 (85.7%) study patients and 9 (69.2%) controls (P=0.385). Complications were mild and transient (n=30), although significantly higher in the controls (n=15; P <0.0001). SLT applied directly to the perilimbal sclera may be as efficacious as the conventional procedure for 1 year.

This study compared percutaneous tibial nerve stimulation (PTNS) versus electrical stimulation with pelvic floor muscle training (ES + PFMT) in women with overactive bladder syndrome (OAB). 60 women with OAB were enrolled. Patients were randomized into two groups. In group A, women underwent ES with PFMT, in group B women underwent PTNS. A statistically significant reduction in the number of daily micturitions, episodes of nocturia and urge incontinence was found in the two groups but the difference was more substantial in women treated with PTNS; voided volume increased in both groups. Quality of life improved in both groups, whereas patient perception of urgency improved only in women treated with PTNS. Global impression of improvement revealed a greater satisfaction in patients treated with PTNS. This study demonstrates the effectiveness of PTNS and ES with PFMT in women with OAB, but greater improvements were found with PTNS. Copyright® by the International Brazilian Journal of Urology.

Subsequently, CT volumetry with the determination of FLRV was performed at weekly intervals, in total three weeks. A sample of twenty patients (group 2) who underwent PVE without HSC application was used as a control group.ResultsThe mean of FLRV increased by 173.2 mL during three weeks after the PVE/HSC procedure,more » whereas by 98.9 mL after PVE only (p = 0.015). Furthermore, the mean daily growth of FLRV by 7.6 mL in group 1 was significantly higher in comparison with 4.1 mL in group 2 (p = 0.007).ConclusionsPVE with the application of HSC significantly facilitates growth of FLRV in comparison with PVE only. This method could be one of the new suitable approaches to increase the resectability of liver tumours.« less

Guidelines in stroke rehabilitation recommend the use of a multidisciplinary approach. Different approaches and techniques with music are used in the stroke rehabilitation to improve motor and cognitive functions but also psychological outcomes. In this randomized controlled pilot trial, relational active music therapy approaches were tested in the post-acute phase of disease. Thirty-eight hospitalized patients with ischemic and hemorrhagic stroke were recruited and allocated in two groups. The experimental group underwent the standard of care (physiotherapy and occupational therapy daily sessions) and relational active music therapy treatments. The control group underwent the standard of care only. Motor functions and psychological aspects were assessed before and after treatments. Music therapy process was also evaluated using a specific rating scale. All groups showed a positive trend in quality of life, functional and disability levels, and gross mobility. The experimental group showed a decrease of anxiety and, in particular, of depression (p = 0.016). In addition, the strength of non-dominant hand (grip) significantly increased in the experimental group (p = 0.041). Music therapy assessment showed a significant improvement over time of non-verbal and sonorous-music relationships. Future studies, including a greater number of patients and follow-up evaluations, are needed to confirm promising results of this study.

This study, aimed to evaluate the difference in mucociliary clearance among volunteers who underwent Ramadan versus Nineveh fasting regimens as well as the difference between the fasting period and 4 weeks following the fasting period in both groups. In this study, two different fasting groups were established: Ramadan (fasting for an average of 15 h for 29 consecutive days, n = 40) and Nineveh (60 h of nonstop fasting, n = 26). Subjects in each group underwent saccharin testing twice: at the end of the fasting period prior to resumption of eating and at 4 weeks after the end of Ramadan or Nineveh fasting. Statistical analysis was performed using the Mann-Whitney U-test, Wilcoxon, Chi-square, and paired t test. A p value less than 0.05 was considered statistically significant. Forty subjects who underwent Ramadan fasting and 26 subjects who underwent Nineveh fasting were included in this study. Of the 66 study participants, 34 (51.5 %) were men and 32 (48.5 %) were women. Their median age was 31 years (range 17-70 years) for Nineveh fasting subjects and 40 years (range 17-70 years) for Ramadan fasting subjects. Chi-square tests revealed no significant difference between the Ramadan and Nineveh fasting groups in gender (p = 0.418), and the Mann-Whitney U-test showed no difference in age. A statistically significant difference was found in the mucociliary clearance time between the Nineveh fasting and non-fasting periods (p = 0.013). Using Wilcoxon signed-rank tests, we found no significant difference in the mucociliary clearance time between the Ramadan fasting and control (4 weeks after the fasting period) periods (p = 0.121). The percentage difference between the fasting and control periods was similar between groups and was not statistically significant for the Ramadan and Nineveh fasting groups (p = 0.086). The results of the present study indicated that long-term fasting with hypohydration contributed to the deterioration of nasal mucociliary clearance. Our data indicate that optimal hydration, sleep patterns, and fasting times contribute to proper mucociliary clearance.

To evaluate the efficacy and safety of cyanoacrylate glue embolization in the treatment of severe arterioportal shunt (APS) presenting with hepatofugal portal venous flow in hepatocellular carcinoma (HCC) patients. Between July 2000 and January 2010, 27 HCC patients with severe APS presenting with hepatofugal portal venous flow underwent transarterial angiography and treatment. Among them, four patients were excluded from the study. Twelve patients underwent transarterial chemoperfusion and embolization of APS with cyanoacrylate glue between January 2006 and January 2010 (Emb group), and the other 11 patients undergoing only transarterial chemoperfusion without embolization of APS between July 2000 and December 2005more » served as a control group (non-Emb group). The change of APS, survival rates, and procedure related complications were analyzed. In the Emb group, APS was improved in all of the 12 patients after initial glue embolization; long-term APS improvement with hepatopetal portal flow was achieved in 80 % (8 of 10) patients who underwent follow-up angiography. Survival rates in the Emb group were 67 % at 6 months, 33 % at 1 year, and 8 % at 2 years, whereas those in the non-Emb group were 0 % at 6 months (P < 0.05). Median survival time in the Emb group was 275 days, which was longer than that of 107 days in the non-Emb group (P = 0.001). There were no major complications in both groups. The preliminary experience suggests that glue embolization may be an effective and safe therapy in the management of severe APS accompanied by HCC and also improve patient survival.« less

To compare the effects of candesartan cilexetil and enalapril maleate on right ventricular myocardial remodeling in dogs with experimentally induced pulmonary stenosis. 24 Beagles. 18 dogs underwent pulmonary arterial banding (PAB) to induce right ventricular pressure overload, and 6 healthy dogs underwent sham operations (thoracotomy only [sham-operated group]). Dogs that underwent PAB were allocated to receive 1 of 3 treatments (6 dogs/group): candesartan (1 mg/kg, PO, q 24 h [PABC group]), enalapril (0.5 mg/kg, PO, q 24 h [PABE group]), or no treatment (PABNT group). Administration of treatments was commenced the day prior to surgery; control dogs received no cardiac medications. Sixty days after surgery, right ventricular wall thickness was assessed echocardiographically and plasma renin activity, angiotensin-converting enzyme activity, and angiotensin I and II concentrations were assessed; all dogs were euthanatized, and collagenous fiber area, cardiomyocyte diameter, and tissue angiotensin-converting enzyme and chymase-like activities in the right ventricle were evaluated. After 60 days of treatment, right ventricular wall thickness, cardiomyocyte diameter, and collagenous fiber area in the PABNT and PABE groups were significantly increased, compared with values in the PABC and sham-operated groups. Chymase-like activity was markedly greater in the PABE group than in other groups. Results indicated that treatment with candesartan but not enalapril effectively prevented myocardial remodeling in dogs with experimentally induced subacute right ventricular pressure overload.

Objective Ischemia/reperfusion (I/R) injury is an important cause of myocardial damage by means of oxidative, inflammatory, and apoptotic mechanisms. The aim of the present study was to examine the potential cardio protective effects of levosimendan in a diabetic rat model of myocardial I/R injury. Methods A total of 18 streptozotocin-induced diabetic Wistar Albino rats (55 mg/kg) were randomly divided into three equal groups as follows: the diabetic I/R group (DIR) in which myocardial I/R was induced following left thoracotomy, by ligating the left anterior descending coronary artery for 60 min, followed by 2 h of reperfusion; the diabetic I/R levosimendan group (DIRL), which underwent I/R by the same method while taking levosimendan intraperitoneal 12 µg kg−1; and the diabetic control group (DC) which underwent sham operations without tightening of the coronary sutures. As a control group (C), six healthy age-matched Wistar Albino rats underwent sham operations similar to the DC group. Two hours after the operation, the rats were sacrificed and the myocardial tissue samples were examined by light microscopy for evidence of myonecrosis and inflammatory cell infiltration. Results Myonecrosis findings were significantly different among groups (p=0.008). Myonecrosis was more pronounced in the DIR group compared with the C, DC, and DIRL groups (p=0.001, p=0.007 and p=0.037, respectively). Similarly, the degree of inflammatory cell infiltration showed significant difference among groups (p<0.0001). Compared with C, DC, and DIRL groups, the inflammatory cell infiltration was significantly higher among the DIR group (p<0.0001, p<0.0001, and p=0.020, respectively). Also, myocardial tissue edema was significantly different among groups (p=0.006). The light microscopic myocardial tissue edema levels were significantly higher in the DIR group than the C, DC, and DIRL groups (p=0.001, p=0.037, and p=0.014, respectively). Conclusion Taken together, our data indicate that levosimendan may be helpful in reducing myocardial necrosis, myocardial inflammation, and myocardial tissue edema resulting from ischemia–reperfusion injury.

To investigate whether internal iliac artery ligation (IIAL) for postpartum hemorrhage (PPH) affects the sexual life in the postpartum period or significantly reduces the clitoral artery blood flow. The women who underwent IIAL due to PPH during cesarean section (CS) were compared with healthy postpartum women delivered by CS between October 2014 and February 2016 in the Gaziantep Women's Health and Maternity Hospital, Gaziantep, Turkey. Clitoral Doppler flow measurements and the Female Sexual Function Index questionnaire (FSFIQ) were performed in all women in the 3rd and 6th postpartum months. This study was registered at ClinicalTrials.gov with the identification number NCT02409602. Mean age, gravidity and parity, body mass index (BMI), first sexual intercourse after childbirth, and education years were similar in both groups. There was no statistically significant difference in the measurements of RI, PI, PSV, EDV, and S/D between the study and control groups in the 3rd month. Lack of statistical significance was also noted between the study and control groups values in the 6th month, as well as between the 3rd and 6th month's values within both the study group and the control group. Additionally, there were no statistically significant differences in the total FSFI scores including sexual desire, sexual arousal, lubrication, orgasm, sexual satisfaction, and pain domain scores between the study and control groups in the 3rd month; between the study and control groups 6th months; whereas all scores were higher in the 6th month compared to the 3rd month within each group. IIAL does not affect the blood flow of the dorsal clitoral artery between the 3rd and 6th months postpartum and between the women who underwent IIAL due to PPH and healthy postpartum women. The sexual function scores were significantly higher in the 6th month compared to the 3rd month in both groups. Copyright © 2017 Elsevier B.V. All rights reserved.

The aim of this study was to investigate the efficacy of tranexamic acid (TA) and methylprednisolone on periorbital edema, ecchymosis, and intraoperative bleeding in patients who underwent open septorhinoplasty (oSRP). Seventy-five patients performing hump extraction and osteotomies were allocated into 3 groups as follows: group 1, 25 patients as control; group 2, 25 patients who were administered oral TA as first dose 1 g starting 2 hours before surgery, 3 g daily in divided doses (1 g, every 8 hours) for 5 days; and group 3, 25 patients who were administered a single dose of 1 mg/kg intravenous methylprednisolone at the beginning of the surgery. Operation time, amount of intraoperative bleeding, and complications were recorded. Scoring of eyelid edema and periorbital ecchymosis was evaluated on postoperative first, third, and seventh days using scale of 0 to 4 by 2 observers. In groups using TA and methylprednisolone, periorbital edema and ecchymosis scores were significantly lower compared with the control group (P < 0.05). No significant difference was seen clinically and statistically in preventing or decreasing both periorbital edema and ecchymosis between group 2 and group 3. Patients given TA showed significantly less intraoperative bleeding compared with controls and patients who were administered methylprednisolone. We observed that the administration of methylprednisolone significantly decreases periorbital edema and ecchymosis. Additionally, our results support that TA use in patients who underwent oSRP with osteotomies was found clinically and statistically effective for prevention of bleeding during oSRP operations and reduction of both periorbital edema and ecchymosis.

To evaluate the role of endometrial injury in the cycle preceding ovarian stimulation for intrauterine insemination (IUI) cycle on the clinical pregnancy rate. This was a prospective randomized controlled trial which included three hundred and thirty two infertile women with an indication for IUI. The subjects were randomly divided into two groups. The intervention group (group A) (n=166) subjects underwent office hysteroscopy with endometrial injury using grasping forceps with teeth, while the control group (group B) (n=166) subjects underwent office hysteroscopy alone without endometrial injury. Primary outcome was clinical pregnancy rate. There were no significant differences in baseline or clinical characteristics between the groups. There were no significant differences in clinical pregnancy rate [13.8% (23/166) versus 12% (20/166); RR 1.15 (95% CI 0.66-2.01), p=0.62]. The abortion rate [4.3% (1/23) versus 15% (3/20); RR 0.29 (95% CI 0.03-2.57), p=0.27], the multiple pregnancy rate [13% (3/23) versus 15% (3/20); RR 0.87 (95% CI 0.20-3.83), p=0.85] and the live birth rate [13.6% (22/166) versus 10.4% (17/166); RR 1.28 (95% CI 0.71-2.32), p=0.42]. There is no evidence of significant difference on the clinical pregnancy rate when endometrial scratching during hysteroscopy is compared to only hysteroscopy in women undergoing IUI.

Objectives: We present a randomized controlled trial of laparoscopic gastric bypass comparing 2 techniques of gastrojejunostomy in patients with morbid obesity. Methods: Eighty consecutive patients underwent laparoscopic Roux-en-Y gastric bypass between September 2005 and August 2006. Patients were randomly assigned to 2 groups by the use of sealed envelopes. In group A, the gastrojejunal anastomosis was performed with a 21-mm circular-stapler, and in group B, this anastomosis was performed with a 45-mm linear-stapler. The rest of the procedure was identical in both groups. Variables evaluated were complications involving the gastrojejunostomy, operative time, length of stay, and percentage of excess weight loss. Results: Both groups were similar in age and body mass index. No patients experienced leakage or gastrojejunal anastomosis fistula, but group A patients had a more frequent stricture rate (P<0.05). Operative time and hospital stay were comparable in both groups (P>0.05). Percentage excess weight loss at one year following surgery was satisfactory in both groups, without a statistically significant difference (P>0.05). Conclusion: Gastrojejunal anastomosis does not seem to be a critical factor in excess weight loss for morbidly obese patients who underwent laparoscopic gastric bypass. The 2 techniques used in this experience are safe and effective; however, the 45-mm liner-stapler is preferable because it has a lower stricture rate. PMID:19275854

The aims of this study are to investigate the changes in spontaneous electrical activities (SEAs) and in acetylcholine (ACh), acetylcholine receptor (AChR), and acetylcholine esterase (AChE) levels after dry needling at myofascial trigger spots in model rats. Forty-eight male Sprague-Dawley rats were divided into four groups. Thirty-six rats were assigned to three model groups, which underwent MTrSs modeling intervention. Twelve rats were assigned to the blank control (BC) group. After model construction, the 36 model rats were randomly subdivided into three groups according to treatment: MTrSs model control (MC) and two dry needling groups. One dry needling group received puncturing at MTrSs (DN-M), whereas the other underwent puncturing at non-MTrSs (DN-nM). Dry needling treatment will last for two weeks, once a week. SEAs and ACh, AChR, and AChE levels were measured after one-week rest of dry needling treatment. The amplitudes and frequencies of endplate noise (EPN) and endplate spike (EPS) significantly decreased after dry needling treatment in the DN-M group. Moreover, ACh and AChR levels significantly decreased, whereas AChE significantly increased after dry needling treatment in the DN-M group. Dry needling at the exact MTrSs is more effective than dry needling at non-MTrSs.

The aim of this study was to investigate whether renal sympathetic denervation (RSD) improves ventricular heart rate (HR) control in patients with persistent atrial fibrillation (AF). Twenty-one patients (aged 57.5 ± 10.2 years, 76.2% male) with persistent AF and hypertension underwent RSD and completed 7-days follow-up evaluations, including 24-hour Holter monitoring (Holter), blood pressure (BP), 24-hour ambulatory BP monitoring (ABPM). Patients were grouped into tertiles of average HR at baseline Holter recording for evaluation of RSD effects on atrioventricular (AV) node (group 1: HR ≧ 90 bpm; group 2: 80 bpm ≦ HR < 90 bpm; group 3: HR < 80 bpm). All patients successfully underwent RSD without any complications. The clinical and procedural characteristics were similar in all groups of patients. No significant changes in BP were observed in the three groups before and after RSD. Compared with baseline, the average HR (Holter) of patients in group 1, 2 and 3 had a reduction of 22.6 ± 13.2 bpm (83.3 ± 4.9 vs 106.0 ± 14.6, P = 0.004), 9.7 ± 7.8 bpm (75.7 ± 7.6 vs 85.4 ± 3.7, P = 0.017) and 2.3 ± 2.9 bpm (71.4 ± 4.0 vs 73.7 ± 4.7, P = 0.089) at 7 days after RSD, respectively. RSD could improve ventricular HR control in patients with persistent AF. RSD slowed AV node conduction in baseline HR-dependent manner. RSD may become an alternative non-pharmaceutical tool for rate control in patients with persistent AF.

Arrayeh, Elnasif; Fidelman, Nicholas, E-mail: nicholas.fidelman@ucsf.edu; Gordon, Roy L.

Purpose: To determine whether transcatheter arterial embolization performed in the setting of active gastric or duodenal nonvariceal hemorrhage is efficacious when the bleeding source cannot be identified angiographically. Methods: Records of 115 adult patients who underwent visceral angiography for endoscopically documented gastric (50 patients) or duodenal (65 patients) nonvariceal hemorrhage were retrospectively reviewed. Patients were subdivided into three groups according to whether angiographic evidence of arterial hemorrhage was present and whether embolization was performed (group 1 = no abnormality, no embolization; group 2 = no abnormality, embolization performed [empiric embolization]; and group 3 = abnormality present, embolization performed). Thirty-day ratesmore » and duration of primary hemostasis and survival were compared.ResultsFor patients with gastric sources of hemorrhage, the rate of primary hemostasis at 30 days after embolization was greater when embolization was performed in the setting of a documented angiographic abnormality than when empiric embolization was performed (67% vs. 42%). The rate of primary hemostasis at 30 days after angiography was greater for patients with duodenal bleeding who either underwent empiric embolization (60%) or embolization in the setting of angiographically documented arterial hemorrhage (58%) compared with patients who only underwent diagnostic angiogram (33%). Patients with duodenal hemorrhage who underwent embolization were less likely to require additional invasive procedures to control rebleeding (p = 0.006). Conclusion: Empiric arterial embolization may be advantageous in patients with a duodenal source of hemorrhage but not in patients with gastric hemorrhage.« less

Postoperative ileus (POI) is one of the most common complications of gastrointestinal surgery. The present study was performed to evaluate the effects of glutamine administration on POI after gastric surgery in humans. The subjects were 31 patients who underwent partial distal gastrectomy for gastric cancer and who were randomly assigned to one of two groups based on postoperative treatment: the glutamine group (3 g/day) and the control group. Manometric recording was done 12 days after surgery, and plasma glutamine concentrations were measured preoperatively and on postoperative day 12. Motor activities of the duodenum in the glutamine group were significantly greater than those of the control group in the interdigestive state. The incidence of phase III motor activity (interdigestive migrating motor contractions) in the glutamine group was significantly higher than that in the control group (60 versus 19%). The glutamine group showed a significantly smaller decrease of plasma glutamine levels compared with the control group. Glutamine could act as a motility-recovery agent after gastrectomy in humans.

Pulmonary vein isolation (PVI) by catheter ablation for atrial fibrillation (AF) requires suppression of patient restlessness by sufficient sedation in addition to maintaining stable respiration. We applied adaptive-servo ventilation (ASV) and examined the effects of ASV combined with deep propofol sedation on PVI using a NavX. We analysed 75 paroxysmal AF (PAF) patients (62 ± 11 years; 53 men and 22 women) who underwent PVI for treatment of PAF using an ASV system combined with deep sedation (ASV group). Control patients included 75 consecutive PAF patients (62 ± 11 years; 51 men and 24 women) who underwent PVI just before introduction of the ASV system. Deep sedation was defined as a Ramsay sedation score of 6. The ASV group had a lower frequency of restless body movements compared with the control group during PVI (1.5 ± 0.7 vs. 7.8 ± 1.4 times, P < 0.01). The frequency of respiratory compensation and EnGuide alignment of catheter position by the NavX was lower in the ASV (4.2 ± 3.3 and 8.8 ± 7.1 times) than control group (7.1 ± 5.1 and 15.2 ± 10.0 times, P < 0.05 and <0.01, respectively). Consequently, significantly lower total electrical energy supply (48.7 ± 6.0 KJ) was required in the ASV than control group (64.5 ± 24.9 KJ, P < 0.01). Further, significantly shorter fluoroscopy and procedural times were observed in the ASV (28 ± 5 and 109 ± 25 min) than the control group (33 ± 6 and 141 ± 38 min, respectively, P < 0.01) and the AF recurrence rate was significantly lower in the ASV than the control group (12 vs. 25%, P < 0.01). ASV combined with deep sedation is an effective strategy during PVI using the NavX in patients with PAF.

Recent studies aimed to evaluate the potential effects of perceptive rehabilitation in Parkinson Disease reporting promising preliminary results for postural balance and pain symptoms. To date, no randomized controlled trial was carried out to compare the effects of perceptive rehabilitation and conventional treatment in patients with Parkinson Disease. To evaluate whether a perceptive rehabilitation treatment could be more effective than a conventional physical therapy program in improving postural control and gait pattern in patients with Parkinson Disease. Single blind, randomized controlled trial. Department of Physical and Rehabilitation Medicine of a University Hospital. Twenty outpatients affected by idiopathic Parkinson Disease at Hoehn and Yahr stage ≤3. Recruited patients were divided into two groups: the first one underwent individual treatment with Surfaces for Perceptive Rehabilitation (Su-Per), consisting of rigid wood surfaces supporting deformable latex cones of various dimensions, and the second one received conventional group physical therapy treatment. Each patient underwent a training program consisting of ten, 45-minute sessions, three days a week for 4 consecutive weeks. Each subject was evaluated before treatment, immediately after treatment and at one month of follow-up, by an optoelectronic stereophotogrammetric system for gait and posture analysis, and by a computerized platform for stabilometric assessment. Kyphosis angle decreased after ten sessions of perceptive rehabilitation, thus showing a substantial difference with respect to the control group. No significant differences were found as for gait parameters (cadence, gait speed and stride length) within Su-Per group and between groups. Parameters of static and dynamic evaluation on stabilometric platform failed to demonstrate any statistically relevant difference both within-groups and between-groups. Perceptive training may help patients affected by Parkinson Disease into restoring a correct midline perception and, in turn, to improve postural control. Perceptive surfaces represent an alternative to conventional rehabilitation of postural disorders in Parkinson Disease. Further studies are needed to determine if the association of perceptive treatment and active motor training would be useful in improving also gait dexterity.

To compare the incidence of femoral access puncture site complications in the control group, who underwent 6 hr of bed rest, with patients in the case group, who underwent 4 hr of bed rest. The ideal bed rest length after percutaneous coronary intervention with a 7-French arterial sheath has been investigated by nursing practice. However, in this larger-sheath-size group, best practices have not been determined, and bed rest time continues to vary markedly among institutions. Retrospective study. Data were retrieved from the National Cardiovascular Data Registry and electronic health records in this retrospective study. Sample size was 401 patients: 152 case patients with 4-hr bed rest and 249 controls with 6-hr bed rest. Case group data were obtained from 20 May 2013-31 December 2014; and control group data, 15 June 2011-20 May 2013. National Cardiovascular Data Registry event rates were generally low in both groups: Only three patients in each group had a bleeding event within 72 hr (2% vs. 1%) and no patient and only two controls had arteriovenous fistula (0% vs. 1%). Complications documented in the electronic health records with institutional femoral access puncture site complication definitions identified bleeding at the access site in eight case patients (5%) and nine controls (4%). Haematoma at the access site occurred in 21 case patients (14%) and 25 controls (10%). The practice change of decreasing bed rest from 6-4 hr for patients with 7-French arterial sheaths post-percutaneous coronary intervention was associated with no significant change in femoral access puncture site complications in either National Cardiovascular Data Registry data or institutional electronic health records data. This introduces expanded evidence of safety in decreasing bed rest length in larger (7-French) arterial sheaths post-percutaneous coronary intervention. © 2017 John Wiley & Sons Ltd.

Neurohormonal activation is a commonly cited array of phenomena in the body's physiologic response to heart failure (HF). The aim of the present study was to determine the change law of serum neurohormones after renal sympathetic denervation (RSD) in dogs with pacing-induced HF. Twenty-eight beagles were randomly divided into control group, RSD group, HF group and HF + RSD group. The control group was implanted pacemakers without pacing; the RSD group underwent renal artery ablation without pacing; the HF group was implanted pacemakers with ventricular pacing at 240 bpm for 3 weeks; and HF + RSD group underwent renal artery ablation and with ventricular pacing at 240 bpm for 3 weeks. Blood samples were taken at baseline, and 3, 6, 9, 12, 15, 18, 21 days in all the dogs for neurohormones measurement. After 3 weeks, the systolic femoral artery pressures in the HF and HF + RSD groups were reduced after pacing 3 weeks. There was an increase significantly in BNP, angiotensin II, aldosterone, endothelin-1 and decrease in renalase after 3 weeks when compared with baseline in HF group. RSD significantly suppressed the changes of plasma neurohormones concentration in experimental HF, but RSD had not obviously impact on the levels of plasma neurohormones during 3 weeks in RSD group. RSD attenuates the changes of levels of plasma neurohormones in the activated renin-angiotensin-aldosterone system (RAAS) but had not obviously effect in the normal physiology of RAAS.

The rodent model is commonly used to study facial nerve injury. Because of the exceptional regenerative capacity of the rodent facial nerve, it is essential to consider the timing when studying facial nerve regeneration and functional recovery. Short-term functional recovery data following transection and repair of the facial nerve has been documented by our laboratory. However, because of the limitations of the head fixation device, there is a lack of long-term data following facial nerve injury. The objective of this study was to elucidate the long-term time course and functional deficit following facial nerve transection and repair in a rodent model. Adult rats were divided into group 1 (controls) and group 2 (experimental). Group 1 animals underwent head fixation, followed by a facial nerve injury, and functional testing was performed from day 7 to day 70. Group 2 animals underwent facial nerve injury, followed by delayed head fixation, and then underwent functional testing from months 6 to 8. There was no statistical difference between the average whisking amplitudes in group 1 and group 2 animals. Functional whisking recovery 6 months after facial nerve injury is comparable to recovery within 1 to 4 months of transection and repair, thus the ideal window for evaluating facial nerve recovery falls within the 4 months after injury.

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) causes skin and soft-tissue infection (SSTI) in military recruits. To evaluate the effectiveness of 2% chlorhexidine gluconate (CHG)-impregnated cloths in reducing rates of SSTI and S. aureus colonization among military recruits. A cluster-randomized (by platoon), double-blind, controlled effectiveness trial. Marine Officer Candidate School, Quantico, Virginia, 2007. Military recruits. Application of CHG-impregnated or control (Comfort Bath; Sage) cloths applied over entire body thrice weekly. Recruits were monitored daily for SSTI. Baseline and serial nasal and/or axillary swabs were collected to assess S. aureus colonization. Of 1,562 subjects enrolled, 781 (from 23 platoons) underwent CHG-impregnated cloth application and 781 (from 21 platoons) underwent control cloth application. The rate of compliance (defined as application of 50% or more of wipes) at 2 weeks was similar (CHG group, 63%; control group, 67%) and decreased over the 6-week period. The mean 6-week SSTI rate in the CHG-impregnated cloth group was 0.094, compared with 0.071 in the control group (analysis of variance model rate difference, 0.025  ± 0.016; P = .14). At baseline, 43% of subjects were colonized with methicillin-susceptible S. aureus (MSSA), and 2.1% were colonized with MRSA. The mean incidence of colonization with MSSA was 50% and 61% (P = .026) and with MRSA was 2.6% and 6.0% (P = .034) for the CHG-impregnated and control cloth groups, respectively. CHG-impregnated cloths applied thrice weekly did not reduce rates of SSTI among recruits. S. aureus colonization rates increased in both groups but to a lesser extent in those assigned to the CHG-impregnated cloth intervention. Antecedent S. aureus colonization was not a risk factor for SSTI. Additional studies are needed to identify effective measures for preventing SSTI among military recruits.

Purpose: To investigate whether three-dimensional conformal radiotherapy (3D-CRT) influences hepatitis B virus (HBV) reactivation and chronic hepatitis B (CHB) exacerbation in patients with HBV-related hepatocellular carcinoma (HCC). Methods and Materials: Of the 48 HCC patients with HBV who underwent 3D-CRT to the liver, 16 underwent lamivudine therapy before and during 3D-CRT (Group 1) and 32 did not receive antiviral therapy before 3D-CRT (Group 2). To analyze spontaneous HBV reactivation, we included a control group of 43 HCC patients who did not receive any specific treatment for HCC or CHB. Results: The cumulative rate of radiation-induced liver disease for Groups 1more » and 2 was 12.5% (2 of 16) and 21.8% (7 of 32), respectively (p > 0.05). The cumulative rate of HBV reactivation was significantly greater in Group 2 (21.8%, 7 of 32) than in Group 1 (0%, 0/16) or the control group (2.3%, 1 of 43; p < 0.05 each). The cumulative rate of CHB exacerbation, however, did not differ significantly between Groups 2 (12.5%, 4 of 32) and 1 (0%, 0 of 16) or the control group (2.3%, 1 of 43; p > 0.05 each). The CHB exacerbations in the 4 Group 2 patients had radiation-induced liver disease features but were differentiated by serum HBV DNA changes. Two of these patients required antiviral therapy and effectively recovered with lamivudine therapy. Conclusions: In patients with HBV-related HCC undergoing 3D-CRT, HBV reactivation and consequent CHB exacerbation should be considered in the differential diagnosis of radiation-induced liver disease, and antiviral therapy might be considered for the prevention of liver function deterioration after RT.« less

Transareolar single-port needlescopic thoracic sympathectomy under intravenous anesthesia without intubation has rarely been attempted in managing primary palmar hyperhidrosis (PPH). The objective of this study is to evaluate the feasibility and safety of this minimally invasive technique. From May 2012 to May 2015, 168 male patients with severe PPH underwent single-port endoscopic thoracic sympathectomy (ETS) and were randomly allocated to groups A or B. Patients in group A underwent nonintubated transareolar ETS with a 2-mm needle endoscope, while those in group B underwent intubated transaxillary ETS with a 5-mm thoracoscope. All procedures were performed successfully. The palms of all patients became dry and warm immediately after surgery. The mean resuscitation time was significantly shorter in nonintubated patients than in intubated patients. Postoperative sore throat occurred in 4 patients in group A and in 32 patients in group B (P < .01). The mean incision length was significantly shorter in group A than in group B. The mean postoperative pain scores were markedly higher in group B than in group A. The mean cost of anesthesia was considerably lower in nonintubated patients than in intubated patients. The mean cosmetic scores were higher in group A than in group B (P < .01). Nonintubated transareolar single-port ETS with a needle endoscope is a safe, effective, and minimally invasive therapeutic procedure, which allows a smaller incision with less pain and excellent cosmetic results. This novel procedure can be performed in a routine clinical practice for male patients with severe PPH.

The high frequency of surgical site infections (SSIs) after hepato-pancreato-biliary (HPB) surgery is a problem that needs to be addressed. This prospective, randomized, controlled study examined whether perioperative prophylactic use of antibiotics based on preoperative bile culture results in HPB surgery could decrease SSI. Participants comprised 126 patients who underwent HPB (bile duct, gallbladder, ampullary, or pancreatic) cancer surgery with biliary reconstruction at Hokkaido University Hospital between August 2008 and March 2013 (UMIN Clinical Trial Registry #00001278). Before surgery, subjects were randomly allocated to a targeted group administered antibiotics based on bile culture results or a standard group administered cefmetazole. The primary endpoint was SSI rates within 30 days after surgery. Secondary endpoint was SSI rates for each operative procedure. Of the 126 patients, 124 were randomly allocated (targeted group, n = 62; standard group, n = 62). Frequency of SSI after surgery was significantly lower in the targeted group (27 patients, 43.5%) than in the standard group (44 patients, 71.0%; P = 0.002). Among patients who underwent pancreaticoduodenectomy and hepatectomy, SSI occurred significantly less frequently in the targeted group (P = 0.001 and P = 0.025, respectively). This study demonstrated that preoperative bile culture-targeted administration of prophylactic antibiotics decreased SSIs following HBP surgery with biliary reconstruction. © 2017 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

To have in-depth analysis of clinical ablation effect of noninvasive radiofrequency field-induced hyperthermia on liver cancer cells, this paper collected liver cancer patients' treatment information from 10 hospitals during January 2010 and December 2011, from which 1050 cases of patients were randomly selected as study object of observation group who underwent noninvasive radiofrequency field-induced hyperthermia treatment; in addition, 500 cases of liver cancer patients were randomly selected as study object of control group who underwent clinical surgical treatment. After treatment was completed, three years of return visit were done, survival rates of the two groups of patients after 1 year, 2 years, and 3 years were compared, and clinical effects of radiofrequency ablation of liver cancer were evaluated. Zoom results show that the two groups are similar in terms of survival rate, and the difference is without statistical significance. 125 patients in observation group had varying degrees of adverse reactions, while 253 patients in control group had adverse reactions. There was difference between groups P < 0.05, with significant statistical significance. It can be concluded that radiofrequency ablation of liver cancer is more secure. Therefore, the results of this study fully demonstrate that liver cancer treatment with noninvasive radiofrequency field-induced hyperthermia is with safety effect and satisfactory survival rate, thus with relatively high clinical value in clinical practice.

We sought to measure angiographic renal frame counts (RFC), as a quantitative angiographic assessment of renal blood flow, to evaluate microvascular compromise due to atheroembolism associated with RAS. Atheroembolism associated with renal artery stenting (RAS) has been implicated as a cause for worsening renal function following successful intervention. Use of a distal embolic protection device (EPD) during RAS has been shown to be safe with debris capture in a high percentage of cases. However, objective benefit for renal function with EPD has been difficult to demonstrate. A control group of 30 consecutive patients (33 kidneys) who underwent RAS without EPD were compared with 33 consecutive patients (33 kidneys) who underwent RAS with EPD using RFC measurement. The prestent and poststent mean RFC for the control group was 30.4 ± 12.1 vs. 23.7 ± 9.9 (P = 0.002) and for the EPD group it was 42.6 ± 12.6 vs. 28.3 ± 9.2 (P < 0.0001). The EPD group had a greater improvement in renal blood flow, manifested by a greater reduction of the RFC (Δ RFC) 14.2 ± 15.2 vs. 6.7 ± 11.7 (P = 0.03) compared with the control group. The use of an EPD was associated with a much larger improvement in renal blood flow (lower RFC) following RAS. This suggests that EPD's may be effective in preventing renal atheroembolic injury and that a controlled trial measuring the impact of EPD's on renal blood flow following RAS should be performed.

The aim of this study was to investigate the impact of structured exercise with jaw mobilizing devices on trismus and its effect on trismus symptomatology and health-related quality of life (HRQL) in head and neck (H&N) cancer patients. Fifty patients with H&N cancer and trismus, i.e. maximum interincisal opening (MIO) ≤ 35 mm participated in a structured intervention program with jaw exercise. The patients in the intervention group underwent a 10-week exercise program with regular follow-up. A control group comprising of 50 patients with trismus and H&N cancer were matched to the intervention group according to gender, tumor location, tumor stage, comorbidity and age. HRQL and trismus-related symptoms were assessed. The mean MIO improvement was 6.4 mm (4.8-8.0) and 0.7 (-0.3-1.7) mm in the intervention group and control group respectively, three months post-intervention commencement (p < 0.001). The intervention group demonstrated a statistically significant improvement in Role functioning, Social functioning and Global quality of life (EORTC QLQ C30) and in all Gothenburg Trismus Questionnaire (GTQ) domains, i.e. jaw-related problems (p < 0.001), eating limitation (p < 0.05) and muscular tension (p < 0.001). We found that a structured jaw exercise program was effective and improved the mouth opening capacity significantly. The objective effect on trismus (MIO) was also reflected in the patient-reported outcome questionnaires where the patients who underwent the structured exercise program after cancer treatment reported improvements in HRQL and less trismus-related symptoms compared to the control group.

Oncologic transoral robotic surgery (TORS) requires in most cases the concurrent or staged surgical treatment of the regional lymph nodes in the neck as well. The purpose of this study was to determine whether the timing of the regional lymphadenectomy (neck dissection) has an impact on the surgical outcomes and on the complication rates. Single-institution, prospective case series with internal control group. Twenty-one patients underwent TORS and appropriate neck dissection concurrently (control group), while 20 patients underwent neck dissection in a timely staged fashion, 8.4 days (median; range, 3-28 days) following their TORS procedure (experimental group). Outcome measures included nodal yield, intraoperative pharyngocervical fistula formation, postoperative fistula formation, postoperative bleeding from the primary and from the neck dissection site, haematoma, seroma, and infection. Nodal yield values, as the oncologic quality indicator of a neck dissection, were comparable in the experimental and in the control group. Complication rates did not differ between the groups: intraoperative and postoperative fistula formation, postoperative bleeding, haematoma and seroma rates were similarly low in the two groups. There was no infection in either group. In the present cohort of 41 TORS-patients, the timing of neck dissection did not make a significant difference in the outcomes. We suggest therefore that aspiring and established TORS-teams do not restrict their appropriate indications due to robotic slot and theatre time constraints, but perform each indicated TORS-case as soon as possible within their given systems, even if the neck dissections cannot be done on the same day.

De Pedro, Daniel; Puglisi, Rosario; Levi, Paul; Pascual, Andrés; Nart, José

To determine whether chemical and thermal stress as well as sharpening are aspects that must be considered to determine when a curette has become too weak to be used safely without the threat of breakage. A total sample of 35 curette blades was divided into 2 principal groups, control (groups 1 to 3) and experimental (groups 4 to 6). The control group was divided into 3 colour-coded groups of 19 similar curette blades and was only subjected to progressive sharpening wear (not sterilised). The test group included 16 Gracey curette blades that were subjected to various degrees of progressive wear and different numbers of sterilisation cycles in 3 subgroups (subgroup 4 had 5 sterilisation cycles; subgroup 5 had 30 cycles and experimental subgroup 6 had 55 cycles). Using a universal testing machine, all blades were tested for strength until they fractured. No evidence was found that the simple presence or absence of sterilisation cycles produced a statistically significant difference between the two studied groups (sterilised and not sterilised). However, when comparing the six subgroups that underwent different numbers of sterilisation cycles, the analysis showed that the more sterilisation cycles a curette underwent, the more likely the curette was to fracture (p = 0.047). Sterilisation by itself does not produce a significant change in the fracture strength, whereas the number of sterilisation cycles clearly weakens the instrument. Sterilisation is a factor to control when evaluating the life of a periodontal curette for the patients' and professionals' safety.

The aim of this study was to assess the efficacy of adjuvant TMZ chemotherapy for newly diagnosed GBM patients who were treated with surgery followed by radiotherapy alone. Between January 2003 and April 2005, 59 consecutive GBM patients underwent radiation therapy after surgical resection and subsequently received TMZ chemotherapy. For the comparative analysis, we selected 60 clinically matched GBM patients who underwent radiotherapy followed by nitrosourea-based chemotherapy (NUBC), at the same institution between June 1995 and April 2005. The study cohort was divided into two groups, those with adjuvant TMZ treatment and with NUBC. 59 patients with adjuvant TMZ treatment were assigned to the treatment group and 60 patients with NUBC to the control group. The median overall survival for the treatment group was 18.2 months (95% CI, 11.7-24.7 months), compared with the survival of 14.5 months (95% CI, 11.2-17.7 months) for the control group (p=0.019). The progression-free survival for the treatment group was 5.6 months (95% CI, 4.4-6.7 months), while the control group showed progression-free survival of 3.3 months (95% CT, 3.2-6.0 months) (p=0.030). Uni- and multivariate analysis revealed that extent of surgical resection, age > or =55 years and postoperative KPS were significantly associated with survival. Adjuvant TMZ chemotherapy provided a clinically relevant benefit of survival, as compared with NUBC. Thus, we suggest that adjuvant TMZ chemotherapy may be effective even for patients who did not receive concomitant chemoradiotherapy for GBM.

Real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback can be used to train localized, conscious regulation of blood oxygen level-dependent (BOLD) signals. As a therapeutic technique, rt-fMRI neurofeedback reduces the symptoms of a variety of neurologic disorders. To date, few studies have investigated the use of self-regulation training using rt-fMRI neurofeedback to enhance cognitive performance. This work investigates the utility of rt-fMRI neurofeedback as a tool to enhance human cognition by training healthy individuals to consciously control activity in the left dorsolateral prefrontal cortex (DLPFC). A cohort of 18 healthy participants in the experimental group underwent rt-fMRI neurofeedback from the left DLPFC in five training sessions across two weeks while 7 participants in the control group underwent similar training outside the MRI and without rt-fMRI neurofeedback. Working memory (WM) performance was evaluated on two testing days separated by the five rt-fMRI neurofeedback sessions using two computerized tests. We investigated the ability to control the BOLD signal across training sessions and WM performance across the two testing days. The group with rt-fMRI neurofeedback demonstrated a significant increase in the ability to self-regulate the BOLD signal in the left DLPFC across sessions. WM performance showed differential improvement between testing days one and two across the groups with the highest increases observed in the rt-fMRI neurofeedback group. These results provide evidence that individuals can quickly gain the ability to consciously control the left DLPFC, and this training results in improvements of WM performance beyond that of training alone.

Controversy exists regarding the appropriate timing for placement of permanent intra-abdominal mesh after inadvertent enterotomy during elective hernia repair. The aim of this study was to examine mesh placement at variable postoperative periods and the subsequent risk of infection. Fifty rodents were divided into five groups. Groups one to four underwent laparotomy, enterotomy, and repair. Physiomesh® was placed at the index operation one, three, or seven days postoperatively in Groups 1, 2, 3, and 4. Group 5 underwent mesh placement only. Necropsy with mesh harvest was performed seven days after placement. Cultures of mesh were obtained and Fisher's exact test was used to compare groups. Bacterial growth postsonication was identified in 30, 30, 50, and 90 per cent versus 20 per cent in controls. Compared with controls, there was significantly increased risk of mesh infection when it was placed seven days after enterotomy (P = 0.006). There was no significant difference in bacterial growth when mesh was placed at the time of enterotomy, one or three days later. The risk of bacterial contamination of permanent mesh placed immediately after inadvertent enterotomy during elective hernia repair is as safe as placing mesh at one or three days. Placing mesh at seven days significantly increased the risk of mesh contamination.

To analyze the effect of cartilage fragments on tunnel widening and tendon-bone integration at 2 years' follow-up after anterior cruciate ligament reconstruction (ACLR). A prospective randomized controlled study was performed in 116 patients who underwent ACLR with autologous hamstring tendons augmented with cartilage fragments (study group, n = 56) or without any augmentation (control group, n = 60). All patients were followed up for 25.6 months (range, 24-28 months), and the International Knee Documentation Committee score, Lysholm score, and visual analog scale score were determined. Computed tomography scans of all patients were obtained 2 years after surgery to evaluate the diameter of the femoral tunnel and thereby assess the amount of tunnel widening. Magnetic resonance imaging evaluation was performed 2 years postoperatively to evaluate the status of the graft in the femoral tunnel. In addition, 5 patients underwent biopsy of the tendon-bone interface at 24 months postoperatively with histologic assessment and transmission electron microscopy. A total of 107 patients completed the follow-up. There were no significant differences between the 2 groups in terms of International Knee Documentation Committee score (P = .07), Lysholm score (P = .10), and visual analog scale score (P = .57) at 24 months' follow-up. The femoral tunnel diameter and the tunnel widening percentage in the study group were significantly smaller than those in the control group (P < .001). The signal-noise quotient value of the graft in the femoral tunnel was 10.4 ± 7.0 in the study group, which was significantly lower than that in the control group (19.5 ± 9.2, P < .001). Histologic studies of the tendon-bone interface showed that there were more bone formations containing chondroid cells with aligned connective tissue in the study group compared with the control group; in addition, the diameter of the collagen fibrils in the study group was considerably thicker than that in the control group (P < .05). The use of cartilage fragments was effective in preventing femoral tunnel widening and seemed to promote the tendon-bone integration process after ACLR.

We assessed morbidity after 2 management strategies for arterial switch operation (ASO) in a single institution: first hours of life surgery and conventional approach. From September 2009 to September 2014, 346 consecutive patients who underwent ASO were enrolled. The study group included 92 patients who underwent ASO in the first 24 hours after birth (group I). The control group consisted of 254 patients who underwent ASO after 24 hours of life in the conventional way (group II). Three outcomes were analyzed: postoperative ventilation time (VT), post-extubation hospital length of stay (peLOS), and a composite morbidity index, defined as postoperative VT + peLOS + occurrence of selected major complications. Overall 30-day survival was 98% (2 [2%] group I vs 5 [2%] group II, P = 1.000). Fifty (13.3%) major complications were observed: 14 (15%) in group I and 36 (15%) in group II (P = 0.635). Although peLOS and morbidity index did not differ significantly between groups, postoperative VT (42 hours [24, 67] vs 27 hours [22, 47], P = 0.008) and total hospital stay were significantly longer in group II (18 days [10, 19] vs 14 days [12, 18]). A median volume of 80 mL (60-100 mL) of autologous umbilical cord blood was collected (80 mL, group 1 vs 60 mL, group II; P = 0.090). Homologous blood cell transfusion was avoided in 70 patients (78%) in group I and in 13 patients (6%) in group II (P < 0.001). Arterial switch operation during the initial 24 hours of life has similar outcomes in view of morbidity and mortality to the conventional approach. Copyright © 2017 Elsevier Inc.

The present study evaluates the outcome of cognitive training as part of Brenner's Integrated Psychological Therapy (IPT) in two groups of individuals with a schizophrenic spectrum disorder (F20-F24 ICD-10). 28 participants were divided into either an experimental group or a control group. The experimental group was composed of 13 individuals (46%) with a mean age of 21.2 years and a mean duration of illness (since their first episode of psychosis FEP) of 15.6 months. The control group included 15 individuals (54%) with a mean age of 25.6 years and a mean duration of illness of 74.4 months (beyond the critical period). Participants underwent an assessment of cognitive functioning which focused on attention, memory, executive functioning and cognitive flexibility as measured by the WCST (Wisconsin Card Sorting Test). Each individual was tested pre- and 6-month post-intervention. The original IPT method was altered by reducing the frequency of sessions to once a week and by limiting our sessions to 2-3 individuals per group. Cognitive flexibility (p<0.01) and long-term memory (p<0.01) improved only in the experimental group. These former skills worsened in the control group (p<0.01). Selective attention, short-term memory and verbal fluency improved in both groups (from p<0.05 to p<0.01). IPT cognitive training, when delivered in the early stages of psychosis (within 18 months from FEP), seems to be particularly effective in improving cognitive flexibility and long-term memory. We did not see improvements in those who had a longer duration of illness who also underwent the same treatment. Cognitive flexibility is linked to clinical insight and social cognition. Therefore, improving this function may lead to a better outcome for patients.

Recurrent cholangitis may aggravate cholestatic liver cirrhosis in biliary atresia (BA) after the Kasai operation. This pilot study aimed to investigate whether Lactobacillus casei rhamnosus has the prophylactic efficacy for recurrent cholangitis in comparison with the conventional neomycin prophylaxis. Twenty jaundice-free patients with BA ages 0 to 3 years who underwent a Kasai operation were enrolled and randomized into 2 groups with 10 patients each: neomycin (25 mg · kg · day for 4 days/wk) and L casei rhamnosus (8 × 10 colony-forming unit per day) groups. The treatment duration was 6 months. Bacterial stool cultures were performed before treatment and 1, 3, and 6 months after starting treatment. In addition, 10 patients with BA with similar status but without prophylaxis served as the historical control group. In the Lactobacillus group, 2 patients (20%, mean 0.03 ± 0.07 episodes per month) developed cholangitis during the study period, with the same frequency as in the neomycin group and significantly lower than that in the control group (80%, P = 0.005, mean 0.22 ± 0.16 episodes per month). The mean change in body weight z score during the 6 months in the Lactobacillus group was 0.97 ± 0.59, which was significantly better than that in the control group (-0.01 ± 0.79, P = 0.006). In bacterial stool cultures, the Lactobacillus and Escherichia coli populations significantly increased and decreased, respectively, in the Lactobacillus group. The use of L casei rhamnosus was as effective as neomycin in preventing cholangitis in patients with BA who underwent Kasai operation, and therefore could be considered as a potential alternative prophylactic regimen.

To evaluate the effect of intracameral carbachol on foveal thickness in patients who underwent uneventful cataract surgery. This retrospective study included two groups: the study group patients (group 1, n = 47 eyes) had uneventful cataract surgery and received only carbachol 0.01 % for miosis; the control group patients (group 2, n = 49 eyes) had uneventful cataract surgery without carbachol or any intracameral medication(s). The groups were compared for foveal thickness after cataract surgery. All phacoemulsification plus intraocular lens implantation surgeries were performed under local anesthesia via temporal clear corneal tunnel incisions. Mean values and standard deviations were calculated for preoperative and postoperative visual acuity (VA) and foveal thickness (FT) at 1 and 4 weeks. Optical coherence tomography was used for the FT measurements, with the MM6 map program. The patients in the study and control groups had a mean age of 57.78 ± 9.07 and 59.72 ± 8.96, respectively (p = 0.355). All eyes had a significant improvement in VA. In the study group, the mean FT at the visits before and 1 and 4 weeks after surgery was 216.87 ± 21.06, 228.81 ± 30.52, and 222.94 ± 29.91 μm, respectively. For the control group, the mean FT, before and 1 and 4 weeks after surgery, was 222.53 ± 17.66, 231.67 ± 23.08, and 225.41 ± 22.59 μm, respectively. Intracameral carbachol 0.01 % had no effect on foveal thickness in patients who underwent uneventful cataract surgery.

High prevalence of asthma and bronchospasm was observed during induction of anesthesia in patients with chronic suppurative otitis mMedia (CSOM) who underwent tympanomastoidectomy. Although several studies have proposed association of allergic diseases with CSOM but no consensus about it has been established. Current study was designed to determine the coincidence of asthma in CSOM patients. In a cross-sectional study, authors investigated medical records of 106 CSOM patients underwent tympanomastoidectomy, aged 15 to 65 years, and 95 controls, which were matched by age and sex. Participants were admitted to Valiasr Hospital, Tehran, Iran, from April of 2011 to March of 2013. Required information, such as demographic characteristics and history of allergic rhinitis (AR) and asthma were obtained from patients' medical records. The prevalence of AR in the CSOM group was higher than controls' group (19.8% and 15.8%, respectively) (P>0.05). Asthma prevalence was significantly higher in patients with CSOM (P=0.03) (OR=7.67, 95% CI:  0.9-62.5). No significant association was found between history of AR and chronic ear infections. However, asthma was significantly more common in CSOM patients. Current study indicates that asthma and risk of bronchospasm need particular attention in patients with CSOM underwent tympanomastoidectomy before and during anesthesia.

This study aims at verifying if impaired sensorimotor control observed in adolescents and young adults with scoliosis is also present in adult patients who underwent surgery to reduce their spine deformation. The study included ten healthy adults and ten adults with idiopathic scoliosis who underwent surgery to reduce their spine deformation. Galvanic vestibular stimulation was delivered to assess sensorimotor control. Vertical forces under each foot and horizontal displacement of the upper body were measured before, during and after stimulation. Balance control was assessed by calculating the root mean square values of kinematic and kinetic variables. The amplitude of the vestibular-evoked postural response was 3.4 % (0.8-6.0 %) and 4.5 % (-0.4 to 9.5 %) of the maximal range of motion. Therefore, spine surgery did not limit the postural response. Patients with idiopathic scoliosis exhibited larger body sway than the healthy controls during and immediately after vestibular stimulation. The maximal normalized lateral displacement of the body was 0.85 and 0.40 cm/m and maximal normalized vertical force was 0.78 vs. 0.39 N/kg, for idiopathic scoliosis and healthy groups, respectively. This result suggests that dysfunctional sensorimotor integration is still present even in adult idiopathic scoliosis that underwent spine deformation correction.

The objective of this study was to investigate the efficacy of combined treatment with vacuum sealing drainage (VSD) and recombinant human epidermal growth factor (rhEGF) for refractory wounds in the extremities, and its effect on serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and IL-2. Ninety-eight patients with refractory wounds in the extremities were recruited and randomly divided into the combined treatment group (underwent VSD and rhEGF treatment) and control group (underwent VSD only) with 49 cases each. Formation of granulation tissue on the wound surface was assessed and scored. The wound healing rate was calculated after 1 week of treatment, and the time of complete healing was recorded. Serum levels of IL-6, IL-2, and TNF-α were measured using enzyme-linked immunosorbent assay. After 1 week of treatment, granulation tissue formation on wound surfaces was significantly improved (p<0.05) compared with that before treatment in both groups. Moreover, granulation tissue formation on wound surfaces was superior in the combined treatment group than in the control group (p<0.05). The wound healing rate was 63.50±4.75% in the combined treatment group and 31.79±3.52% in the control group, and the difference was statistically significant (p<0.05). The time of complete healing was 15.11±2.24 days in the combined treatment group and 19.63±2.76 days in the control group, and the difference was statistically significant (p<0.05). The serum levels of IL-6, IL-2, and TNF-α, in the two groups were significantly lower than those before treatment (p<0.05). Moreover, the levels in the combined treatment group were significantly lower than those in the control group (p<0.05). In conclusion, combined treatment with VSD and rhEGF reduced inflammation and shortened the time of complete healing of refractory wounds in the extremities. Measurement of the levels of related inflammatory factors provided a reference for the prognosis of refractory wounds. PMID:29250151

This study was to investigate the effects of Mirror Therapy (MT) combined with Neuromuscular Electrical Stimulation (NMES) on muscle strength and tone, motor function, balance, and gait ability in stroke survivors with hemiplegia. This study was a randomized controlled trial. Twenty-seven hemiplegic stroke survivors from a rehabilitation center participated in the study. The participants were randomly assigned to either an experimental or a control group. The experimental group (n = 14) underwent MT combined with NMES and conventional physical therapy, and the control group (n = 13) underwent conventional physical therapy alone. Muscle strength and tone, balance, and gait ability were examined at baseline and after 4 weeks of intervention. A hand-held dynamometer was used to assess muscle strength, the Modified Ashworth Scale (MAS) was used to assess muscle tone, the Berg Balance Scale (BBS) and Timed Up and Go test (TUG) were used to ascertain balance, and the 6-m Walk Test (6mWT) was used to examine gait ability. After the intervention, compared to baseline values, there were significant improvements in muscle strength and MAS, BBS, TUG, and 6mWT values in the experimental group (P< 0.05). In addition, at post-intervention, there were significant differences between the two groups in muscle strength and BBS (P< 0.05). MT combined with NMES may effectively improve muscle strength and balance in hemiplegic stroke survivors. However, further studies are necessary to demonstrate brain reorganization after MT combined with NMES.

Hand dermatitis in soldiers is a considerable problem. The purpose of the study was to evaluate appropriate screening tests to improve the diagnosis of hand dermatitis in soldiers. A group of 111 soldiers with occupational dermatitis from contact with fuels and oils underwent "tailored patch tests" with allergens relevant to their field of work and their environment. The control group consisted of 24 soldiers with various jobs similar to those of civilian life, who had not been exposed to oils and fuels. Seventy-three civilian patients, attending the clinic for patch testing, were also included. Twenty soldiers, who had a history of intensive contact with oil and fuels, but no contact dermatitis, and who were admitted because of various skin diseases (fungal infections, acne, etc.) also underwent the supplemental testing and served as an additional control group. Of the soldiers, 31 (29%) showed one or more positive skin tests of the oil series and 30 patients of this group one or more positive reactions to the standard patch tests trays. No patient of the control groups had a positive test to the oil series. Our results show the value of the supplementary tests as a first-step screening test for detection of oil allergy in soldiers and automobile-mechanics or in workers handling other gasoline- or diesel-powered engineering equipment. The test method appears to be practical, easy to perform, reliable and giving clear and accurate results, with a negligible rate of false positive reactions.

OBJECTIVE Contralateral peripheral neurotization surgery has been successfully applied to rescue motor function of the hemiplegic upper extremity in patients with central neurological injury (CNI). It may contribute to strengthened neural pathways between the contralesional cortex and paretic limbs. However, the effect of this surgery in the lower extremities remains unknown. In the present study the authors explored the effectiveness and safety of contralateral peripheral neurotization in treating a hemiplegic lower extremity following CNI in adult rats. METHODS Controlled cortical impact (CCI) was performed on the hindlimb motor cortex of 36 adult Sprague-Dawley rats to create severe unilateral traumatic brain injury models. These CCI rats were randomly divided into 3 groups. At 1 month post-CCI, the experimental group (Group 1, 12 rats) underwent contralateral L-6 to L-6 transfer, 1 control group (Group 2, 12 rats) underwent bilateral L-6 nerve transection, and another control group (Group 3, 12 rats) underwent an L-6 laminectomy without injuring the L-6 nerves. Bilateral L-6 nerve transection rats without CCI (Group 4, 12 rats) and naïve rats (Group 5, 12 rats) were used as 2 additional control groups. Beam and ladder rung walking tests and CatWalk gait analysis were performed in each rat at baseline and at 0.5, 1, 2, 4, 6, 8, and 10 months to detect the skilled walking functions and gait parameters of both hindlimbs. Histological and electromyography studies were used at the final followup to verify establishment of the traumatic brain injury model and regeneration of the L6-L6 neural pathway. RESULTS In behavioral tests, comparable motor injury in the paretic hindlimbs was observed after CCI in Groups 1-3. Group 1 started to show significantly lower slip and error rates in the beam and ladder rung walking tests than Groups 2 and 3 at 6 months post-CCI (p < 0.05). In the CatWalk analysis, Group 1 also showed a higher mean intensity and swing speed after 8 months post-CCI and a longer stride length after 6 months post-CCI than Groups 2 and 3 (p < 0.05). Transection of L-6 resulted in transient skilled walking impairment in the intact hindlimbs in Groups 1 and 2 (compared with Group 3) and in the bilateral hindlimbs in Group 4 (compared with Group 5). All recovered to baseline level within 2 months. Histological study of the rat brains verified comparable injured volumes among Groups 1-3 at final examinations, and electromyography and toluidine blue staining indicated successful regeneration of the L6-L6 neural pathways in Group 1. CONCLUSIONS Contralateral L-6 neurotization could be a promising and safe surgical approach for improving motor recovery of the hemiplegic hindlimb after unilateral CNI in adult rats. Further investigations are needed before extrapolating the present conclusions to humans.

Motor relearning protocols should involve task-oriented movement, focused attention, and repetition of desired movements. To investigate the effect of intensive gait training with rhythmic auditory stimulation on postural control and gait performance in individuals with chronic hemiparetic stroke. Twenty patients with chronic hemiparetic stroke participated in this study. Subjects in the Rhythmic auditory stimulation training group (10 subjects) underwent intensive gait training with rhythmic auditory stimulation for a period of 6 weeks (30 min/day, five days/week), while those in the control group (10 subjects) underwent intensive gait training for the same duration. Two clinical measures, Berg balance scale and stroke specific quality of life scale, and a 2-demensional gait analysis system, were used as outcome measure. To provide rhythmic auditory stimulation during gait training, the MIDI Cuebase musical instrument digital interface program and a KM Player version 3.3 was utilized for this study. Intensive gait training with rhythmic auditory stimulation resulted in significant improvement in scores on the Berg balance scale, gait velocity, cadence, stride length and double support period in affected side, and stroke specific quality of life scale compared with the control group after training. Findings of this study suggest that intensive gait training with rhythmic auditory stimulation improves balance and gait performance as well as quality of life, in individuals with chronic hemiparetic stroke.

Rapamycin is an immunosuppressive agent with marked antiproliferative properties and is effective in reducing in stent restenosis and vein graft neointimal hyperplasia. Apoptosis is one mechanism counterbalancing cellular proliferation. We therefore investigated the role of apoptosis in rapamycin treated vein grafts in a mouse model. C57BL6J mice underwent interposition of the inferior vena cava from isogenic donor mice into the common carotid artery using a cuff technique. In the treatment group 200 microg of rapamycin were applied locally in pluronic gel. The control group did not receive local treatment. Vein grafts were harvested at 4 weeks postoperatively and underwent morphometric analysis as well as immunohistochemical analysis for apoptosis (TUNEL). In grafted veins without treatment (controls) neointimal thickness was 50 (12-58) microm at 4 weeks postoperatively. In 200 microg rapamycin treated grafts the neointimal thickness was 17 (5-55) microm. Rapamycin treated vein grafts showed a significantly increased rate of apoptosis in the adventitia as compared with controls (P=0.032). In the neointima the apoptosis rate was lower in both groups with no significant difference between rapamycin treated grafts and controls. We conclude that treatment of experimental vein grafts with rapamycin is associated with an increased apoptosis rate in the vascular wall and a trend towards reduction of neointimal hyperplasia. These results suggest that apoptosis may be a beneficial antiproliferative component for the treatment of vein graft disease.

Due to the floating of the guideline, there is no evidence-based evaluation index on when to start the blood transfusion for patients with hemoglobin (Hb) level between 7 and 10 g/dl. As a result, the trigger point of blood transfusion may be different in the emergency use of the existing transfusion guidelines. The present study was designed to evaluate whether the scheme can be safely and effectively used for emergency patients, so as to be supported by multicenter and large sample data in the future. From June 2013 to June 2014, patients were randomly divided into the experimental group (Peri-operative Transfusion Trigger Score of Emergency [POTTS-E] group) and the control group (control group). The between-group differences in the patients' demography and baseline information, mortality and blood transfusion-related complications, heart rate, resting arterial pressure, body temperature, and Hb values were compared. The consistency of red blood cell (RBC) transfusion standards of the two groups of patients with the current blood transfusion guideline, namely the compliance of the guidelines, utilization rate, and per-capita consumption of autologous RBC were analyzed. During the study period, a total of 72 patients were recorded, and 65 of them met the inclusion criteria, which included 33 males and 32 females with a mean age of (34.8 ± 14.6) years. 50 underwent abdomen surgery, 4 underwent chest surgery, 11 underwent arms and legs surgery. There was no statistical difference between the two groups for demography and baseline information. There was also no statistical differences between the two groups in anesthesia time, intraoperative rehydration, staying time in postanesthetic care unit, emergency hospitalization, postoperative 72 h Acute Physiologic Assessment and Chronic Health Evaluation II scores, blood transfusion-related complications and mortality. Only the POTTS-E group on the 1 st postoperative day Hb was lower than group control, P < 0.05. POTTS-E group was totally (100%) conformed to the requirements of the transfusion guideline to RBC infusion, which was higher than that of the control group (81.25%), P < 0.01.There were no statistical differences in utilization rates of autologous blood of the two groups; the utilization rates of allogeneic RBC, total allogeneic RBC and total RBC were 48.48%, 51.5%, and 75.7% in POTTS-E group, which were lower than those of the control group (84.3%, 84.3%, and 96.8%) P < 0.05 or P < 0.01. Per capita consumption of intraoperative allogeneic RBC, total allogeneic RBC and total RBC were 0 (0, 3.0), 2.0 (0, 4.0), and 3.1 (0.81, 6.0) in POTTS-E groups were all lower than those of control group (4.0 [2.0, 4.0], 4.0 [2.0, 6.0] and 5.8 [2.7, 8.2]), P < 0.05 or P < 0.001. Peri-operative Transfusion Trigger Score-E evaluation scheme is used to guide the application of RBC. There are no differences in the recent prognosis of patients with the traditional transfusion guidelines. This scheme is safe; Compared with doctor experience-based subjective assessment, the scoring scheme was closer to patient physiological needs for transfusion and more reasonable; Utilization rate and the per capita consumption of RBC are obviously declined, which has clinical significance and is feasible. Based on the abovementioned three points, POTTS-E scores scheme is safe, reasonable, and practicable and has the value for carrying out multicenter and large sample clinical researches.

Children with malformations of cortical development (MCD) frequently have associated cognitive impairments which reduce quality of life. We hypothesized that cognitive deficits associated with MCD can be improved with environmental manipulation or additional training. The E17 methylazoxymethanol acetate (MAM) exposure model bears many anatomical hallmarks seen in human MCDs as well as similar behavioral and cognitive deficits. We divided control and MAM exposed Sprague-Dawley rats into enriched and non-enriched groups and tested performance in the Morris water maze. Another group similarly divided underwent sociability testing and also underwent Magnetic Resonance Imaging (MRI) scans pre and post enrichment. A third group of control and MAM rats without enrichment were trained until they reached criterion on the place avoidance task. MAM rats had impaired performance on spatial tasks and enrichment improved performance of both control and MAM animals. Although MAM rats did not have a deficit in sociability they showed similar improvement with enrichment as controls. MRI revealed a whole brain volume decrease with MAM exposure, and an increase in both MAM and control enriched volumes in comparison to non-enriched animals. In the place avoidance task, MAM rats required approximately 3 times as long to reach criterion as control animals, but with additional training were able to reach control performance. Environmental manipulation and additional training can improve cognition in a rodent MCD model. We therefore suggest that patients with MCD may benefit from appropriate alterations in educational strategies, social interaction and environment. These factors should be considered in therapeutic strategies. PMID:24358362

Complete mesocolic excision (CME) has been proposed for colon cancer to improve oncological outcomes. The risks and benefits of laparoscopic CME have not been examined fully. We compared short- and long-term outcomes of CME with a conventional mesocolic excision (non-CME) in laparoscopic right hemicolectomy (RHC) for right-sided colon cancer. In total, 115 patients who underwent laparoscopic RHC with stage I-III right-sided colon cancer at Busan Paik Hospital from August 2007 to October 2011 were enrolled in this case-control study. Three trained colorectal surgeons reviewed videos of the surgeries; patients were divided into two groups: those who underwent a CME (CME group, n = 34) and those who underwent a conventional mesocolic excision (non-CME group, n = 81). There was no significant difference between the CME and non-CME groups in operative time, post-operative complications, or hospital stay. However, the CME group had more lymph nodes harvested (P < 0.001) and lower blood loss (P = 0.016) versus the non-CME group. There was no difference in 5-year disease-free survival rate between the groups, but 5-year overall survival rate was 100% in the CME group and 89.49% in the non-CME group (P < 0.05). Laparoscopic RHC with CME is safe and associated with better 5-year overall survival rate than non-CME for patients with stage I-III right-sided colon cancer. Implementation of CME surgery might improve oncological outcomes for patients with right-sided colon cancer. © 2018 Royal Australasian College of Surgeons.

Optimizing hearing in patients with cleft lip and/or palate (CLP) by early recognition and management of otitis media with effusion is essential for speech development. Some evidence has suggested higher complication rates from ventilation tube (VT) insertion in patients with CLP and has led to a trend not to treat these patients surgically. However, studies have failed to match comparison groups for age and sex. To compare complication rates from VT insertion in pediatric patients with and without CLP. The study used a nested case-control design to evaluate 60 pediatric patients with CLP who underwent VT insertion at a children's hospital. The control group of age- and sex-matched patients was selected from a database of 2943 VT insertions. All patients were administered general anesthesia and underwent VT insertion by a pediatric otorhinolaryngology (ENT) team. The primary outcomes were numbers of otorrhea complications. Secondarily, rates of attendance at an ENT clinic specifically for complications were evaluated. Finally, numbers of complications other than otorrhea were assessed but not statistically analyzed owing to the varied types and low numbers in each group. The control cohort had 151 documented cases of otorrhea compared with 121 in the CLP group (ratio 1.25:1); the difference between groups was not statistically significant (P = .52). There was no significant difference in mean ENT clinic visits per patient for complications between groups (0.80 in the CLP group, 0.78 for controls) (P = .66). Regarding complications other than otorrhea, the control group reported more than the CLP group (43 vs 25; ratio, 1.7:1). Complication rates of VT placement among patients with CLP were not higher than those among patients without CLP. Therefore, treatment with VT insertion should be administered to patients with CLP under the same guidelines as for those without CLP. Indeed, there could be an argument for a shift in practice toward more aggressive treatment of patients with CLP, who are already vulnerable to speech and social developmental delay.

Pain and urinary symptoms following colorectal cancer (CRC) surgery are frequent and carry a poor recovery. This study tested the effects of inhalation of Lavandula angustifolia Mill. (lavender) oil or linalyl acetate on pain relief and lower urinary tract symptoms (LUTS) following the removal of indwelling urinary catheters from patients after CRC surgery. This randomised control study recruited 66 subjects with indwelling urinary catheters after undergoing CRC surgery who later underwent catheter removal. Patients inhaled 1% lavender, 1% linalyl acetate, or vehicle (control group) for 20 minutes. Systolic and diastolic blood pressure (BP), heart rate, LUTS, and visual analog scales of pain magnitude and quality of life (QoL) regarding urinary symptoms were measured before and after inhalation. Systolic BP, diastolic BP, heart rate, LUTS, and QoL satisfaction with urinary symptoms were similar in the three groups. Significant differences in pain magnitude and urinary residual sense of indwelling catheters were observed among the three groups, with inhalation of linalyl acetate being significantly more effective than inhalation of lavender or vehicle. Inhalation of linalyl acetate is an effective nursing intervention to relieve pain and urinary residual sense of indwelling urinary catheters following their removal from patients who underwent CRC surgery.

Correlating symptoms and physical examination findings with surgical levels based on common imaging results is not reliable. In patients who have no concordance between radiological and clinical symptoms, the surgical levels determined by conventional magnetic resonance imaging (MRI) and neurogenic examination (NE) may lead to a more extensive surgery and significant complications. We aimed to confirm that whether the use of diffusion tensor imaging (DTI) and paraspinal mapping (PM) techniques can further prevent the occurrence of false positives with conventional MRI, distinguish which are clinically relevant from levels of cauda equina and/or nerve root lesions based on MRI, and determine and reduce the decompression levels of lumbar spinal stenosis than MRI + NE, while ensuring or improving surgical outcomes. We compared the data between patients who underwent MRI + (PM or DTI) and patients who underwent conventional MRI + NE to determine levels of decompression for the treatment of lumbar spinal stenosis. Outcome measures were assessed at 2 weeks, 3 months, 6 months, and 12 months postoperatively. One hundred fourteen patients (59 in the control group, 54 in the experimental group) underwent decompression. The levels of decompression determined by MRI + (PM or DTI) in the experimental group were significantly less than that determined by MRI + NE in the control group (p = 0.000). The surgical time, blood loss, and surgical transfusion were significantly less in the experimental group (p = 0.001, p = 0.011, p = 0.001, respectively). There were no differences in improvement of the visual analog scale back and leg pain (VAS-BP, VAS-LP) scores and Oswestry Disability Index (ODI) scores at 2 weeks, 3 months, 6 months, and 12 months after operation between the experimental and control groups. MRI + (PM or DTI) showed clear benefits in determining decompression levels of lumbar spinal stenosis than MRI + NE. In patients with lumbar spinal stenosis, the use of PM and DTI techniques reduces decompression levels and increases safety and benefits of surgery.

For chronic rhinitis that is refractory to medical therapy, surgical intervention such as endoscopic vidian neurectomy (VN) can be used to control the intractable symptoms. Lasers can contribute to minimizing the invasiveness of ENT surgery. The aim of this retrospective study is to compare in patients who underwent diode laser-assisted versus traditional VN in terms of operative time, surgical field, quality of life, and postoperative complications. All patients had refractory rhinitis with a poor treatment response to a 6-month trial of corticosteroid nasal sprays and underwent endoscopic VN between November 2006 and September 2015. They were non-randomly allocated into either a cold instrument group or a diode laser-assisted group. Vidian nerve was excised with a 940-nm continuous wave diode laser through a 600-μm silica optical fiber, utilizing a contact mode with the power set at 5 W. A visual analog scale (VAS) was used to grade the severity of the rhinitis symptoms for quality of life assessment before the surgery and 6 months after. Of the 118 patients enrolled in the study, 75 patients underwent cold instrument VN and 43 patients underwent diode laser-assisted VN. Patients in the laser-assisted group had a significantly lower surgical field score and a lower postoperative bleeding rate than those in the cold instrument group. Changes in the VAS were significant in preoperative and postoperative nasal symptoms in each group. The application of diode lasers for vidian nerve transection showed a better surgical field and a lower incidence of postoperative hemorrhage. Recent advancements in laser application and endoscopic technique has made VN safer and more effective. We recommend this surgical approach as a reliable and effective treatment for patients with refractory rhinitis.

In deep inferior epigastric artery perforator (DIEP) flap breast reconstruction, abdominal donor-site cosmetic and sensibility outcomes and the closure technique have drawn little attention in the literature, with many surgeons still following the principles of standard abdominoplasty. In this article, the authors report their experience with the cannula-assisted, limited undermining, and progressive high-tension suture ("CALP") technique of DIEP donor-site closure compared with standard abdominoplasty. Between December of 2008 and January of 2013, 137 consecutive women underwent DIEP flap breast reconstruction. Of these, 82 patients (between December of 2008 and November of 2011) underwent DIEP flap donor-site closure by means of standard abdominoplasty (control group) and 55 patients (from December of 2011 to January of 2013) by means of cannula-assisted, limited undermining, and progressive high-tension suture (study group). The abdominal drainage daily output, donor-site complications, abdominal skin sensitivity at 1-year follow-up, cosmetic outcomes, and patient satisfaction were recorded and analyzed statistically. Daily drainage output was significantly lower in the study group. Donor-site complications were significantly higher in the control group (37.8 percent versus 9 percent). Seroma and wound healing problems were experienced in the control group. Abdominal skin sensibility was better preserved in the study group. Overall, abdominal wall aesthetic outcomes were similar in both groups, except for scar quality (better in the study group). According to the authors' experience, cannula-assisted, limited undermining, and progressive high-tension suture should be always preferred to standard abdominoplasty for DIEP donor-site closure to reduce the complication rate to improve abdominal skin sensitivity and scar quality.

To retrospectively determine the safety and efficacy of combined chemotherapy with carmustine (BCNU) wafer, bevacizumab, and temozolomide plus radiotherapy in patients with newly diagnosed glioblastoma (GBM). A total of 54 consecutive newly diagnosed GBMs were resected at our institution between 2010 and 2016. Twenty-nine patients underwent BCNU wafer implantation into the resection cavity followed by standard radiochemotherapy with temozolomide (TMZ, Stupp regimen) plus additional bevacizumab treatment between 2013 and 2016. Twenty-five patients who underwent resection without BCNU implantation between 2010 and 2012 were enrolled as a control group; these patients were treated with the Stupp regimen and did not receive bevacizumab. This retrospective study included evaluation of progression-free survival and overall survival, plus comparisons between the combined therapy group and the control group. There were no significant differences in age, sex, Karnofsky Performance Status on admission, isocitrate dehydrogenase 1/2 mutation ratio, or resection rate between the combined and standard therapy groups. The median overall survival in the combined therapy group and control group was 24.2 months and 15.30, respectively (P = 0.027). The median progression-free survival was 16.8 months and 7.30 months, respectively (P = 0.009). Overall, the incidence of adverse events leading to discontinuation of the study drug was similar between the treatment groups, except for infection, which was more common in the combined treatment group and required repeat surgery. The combined therapy showed higher efficacy compared with standard therapy in patients with GBM. Therefore, combined therapy seems to be effective with an acceptable toxicity profile.

Although cardiac rehabilitation is known as a tool to reduce the overall risk of cardiovascular complications, its specific role in the reduction of hs-CRP as a marker of inflammation and a proven marker of cardiovascular risk needs further investigation. The present study aims at elucidating the effects of a full course of conventional cardiac rehabilitation program for the period of eight weeks, on the levels of hs-CRP in patients who underwent isolated coronary artery bypass surgery. In this case study, 30 consecutive patients who underwent isolated coronary artery bypass surgery (isolated CABGS), and a full 8-week cardiac rehabilitation program in Tehran Heart Center, were investigated. A group of 30 similar patients, who enrolled in the same period of rehabilitation program but did not participate in practice, was considered as a control group. Serum levels of hs-CRP in both groups were measured retrospectively and in similar days before the start of rehabilitation program and at the end of it (or 8 weeks after initial registration for the control group). Levels of hs-CRP in the rehabilitation group and control group were 5.9 7.7 and 6.3 6.9 respectively before start of the program which was not statistically meaningful ( P -Value = 0.833). However, after the program, level of hs-CRP in the two tested groups changed to 2.3 5.1 and 5.7 6.1 respectively which showed a meaningful correlation ( P -Value = 0.023). These results also showed that decrease in hs-CRP level in the rehabilitated group but not in the control group was statistically meaningful (with P -Value of 0.037 and 0.0723 respectively). In patients undergoing coronary bypass surgery, participating in a full course of cardiac rehabilitation for 8 weeks has resulted in a significant reduction in hs-CRP levels as a marker of cardiovascular risk.

Robot-assisted gait training (RAGT) is effective for improving dynamic balance and aerobic capacity, but previous RAGT method does not set suitable training intensity. Recently, high-intensity treadmill gait training at 70% of heart rate reserve (HRR) was used for improving aerobic capacity and dynamic balance. This study was designed to compare the effectiveness between objective and subjective methods of high-intensity RAGT for improving dynamic balance and aerobic capacity in chronic stroke. Subjects were randomly allocated into experimental (n = 17) and control (n = 17) groups. The experimental group underwent high-intensity RAGT at 70% of HRR, whereas the control group underwent high-intensity RAGT at an RPE of 15. Both groups received their assigned training for 30 min per session, 3 days per week for 6 weeks. All subjects also received an additional 30 min of conventional physical therapy. Before and after each of the 18 sessions, the dynamic balance and aerobic capacity of all subjects were evaluated by a blinded examiner. After training, Berg Balance Scale (BBS) and Timed Up and Go Test scores, VO 2 max, and VO 2 max/kg were significantly increased in both groups (p < 0.05). These variables in experimental group were significantly greater than control group. However, the BBS score was not significantly different between both groups. All subjects completed high-intensity RAGT. No adverse effect of training was observed in both groups. High-intensity RAGT at 70% of HRR significantly improved dynamic balance and aerobic capacity more than RAGT at RPE of 15. These results suggest that high-intensity RAGT at 70% of HRR is safe and effective for improving dynamic balance and aerobic capacity in chronic stroke.

To assess mortality and treatment costs of a new management protocol with preferential use of emergency endovascular aneurysm repair (eEVAR) for acute abdominal aortic aneurysm (AAA). From September 2003 until February 2005, 49 consecutive patients (45 men; mean age 71 years) with acute AAA were entered into a prospective study of a new management protocol that featured preferential use of eEVAR (n=18); patients with unsuitable anatomy or who were hemodynamically unstable underwent open repair (n=31). Mortality data and costs of treatment were compared in this mixed prospective group to a historical control group consisting of 147 patients (128 men; mean age 71 years) who underwent open repair from January 1998 to December 2001. All direct medical costs were included from the moment of admission until discharge from the hospital. Mortality in the mixed prospective group (18%) was lower than in the historical control group (31%), but the difference did not reach statistical significance (p=0.099). The mean total cost in the mixed prospective group was 17,164 euro compared to 21,084 euro in the historical open repair group (p=0.255). A preferential eEVAR protocol for acute AAA can decrease mortality and does not increase overall costs during initial treatment, but larger studies are needed to determine if these trends are statistically significant.

To investigate the agents of bacterial contamination of contact lenses after corneal collagen cross-linking (CCL), and to present the possible changes of ocular flora after riboflavin/ultraviolet A. Seventy-two contact lenses of patients who underwent CCL and 41 contact lenses of patients who underwent photorefractive keratectomy (PRK) as control group were enrolled to the study. After 48 h of incubation, broth culture media was transferred to plates. Samples were accepted as positive if one or more colony-forming units were shown. There were positive cultures in 12 (16.7%) contact lenses in the CCL group and 5 (12.2%) had positive cultures in PRK group. Coagulase-negative staphlycocci (CNS) were the most frequent microorganism. Alpha hemolytic streptococci and Diphteroid spp. were the other isolated microorganisms. Bacterial colonization can occur during and early after the CCL procedure in epithelial healing. To prevent corneal infections after the treatment, prophylactic antibiotics should be prescribed.

The goal of this study was to investigate the effects of pulmonary static inflation with 50% xenon on postoperative oxygen impairment during cardiopulmonary bypass (CPB) for Stanford type A acute aortic dissection (AAD). This prospective single-center nonrandomized controlled clinical trial included 100 adult patients undergoing surgery for Stanford type A AAD at an academic hospital in China. Fifty subjects underwent pulmonary static inflation with 50% oxygen from January 2013 to January 2014, and 50 underwent inflation with 50% xenon from January 2014 to December 2014. During CPB, the lungs were inflated with either 50% xenon (xenon group) or 50% oxygen (control group) to maintain an airway pressure of 5 cm H2O. The primary outcome was oxygenation index (OI) value after intubation, and 10 minutes and 6 hours after the operation. The second outcome was cytokine and reactive oxygen species levels after intubation and 10 minutes, 6 hours, and 24 hours after the operation. Patients treated with xenon had lower OI levels compared to the control group before surgery (P = 0.002); however, there was no difference in postoperative values between the 2 groups. Following surgery, mean maximal OI values decreased by 18.8% and 33.8%, respectively, in the xenon and control groups. After surgery, the levels of interleukin-6 (IL-6), tumor necrosis factor alpha, and thromboxane B2 decreased by 23.5%, 9.1%, and 30.2%, respectively, in the xenon group, but increased by 10.8%, 26.2%, and 26.4%, respectively, in the control group. Moreover, IL-10 levels increased by 28% in the xenon group and decreased by 7.5% in the control group. There were significant time and treatment-time interaction effects on methane dicarboxylic aldehyde (P = 0.000 and P = 0.050, respectively) and myeloperoxidase (P = 0.000 and P = 0.001 in xenon and control groups, respectively). There was no difference in hospital mortality and 1-year survival rate between the 2 groups. Pulmonary static inflation with 50% xenon during CPB could attenuate OI decreases at the end of surgery for Stanford type A AAD. Thus, xenon may function by triggering anti-inflammatory responses and suppressing pro-inflammatory and oxidative effects.

Although the goal of cleft palate (CP) repair is to achieve normal speech, no standard procedure ensures that patients' speech will be at the same level as speech in children without CP. In this study, postoperative speech outcomes following primary CP repair combined with or without a mucosal graft was analyzed in comparison with that of control subjects without CP. Eighty-two patients who underwent modified V-Y palatoplasty with a mucosal graft on the nasal side for symmetrical muscular reconstruction during 2006-2012 (MG group) and 109 patients who previously underwent modified V-Y palatoplasty without a mucosal graft (non-MG group) were enrolled in this study. Speech data on 37 Japanese subjects without CP were used as a control. Perceptual rating of resonance and nasal emission and nasometry were carried out for all participants. Furthermore, cephalometric analyses were performed to assess postoperative velopharyngeal morphology and velar movement. Normal resonance was achieved at a significantly higher rate (90.3% of patients) in the MG group than in the non-MG group (68.8%) (P < .01). The mean nasalance scores in the MG group were significantly lower (P < .01) and were almost at the same level as in controls. Cephalometric analyses revealed a greater velar length and velar elevation angle during phonation in the MG group (P < .01 and P < .05, respectively). Modified V-Y palatoplasty combined with a mucosal graft on the nasal side of the velum for symmetrical muscular reconstruction facilitates speech outcomes for children with cleft palate that are comparable with those for peers without CP.

Night extension splinting has been used to treat patients with Dupuytren contracture to improve active range of motion (AROM) of the hand. A published case study demonstrated the benefit of splinting following needle aponeurotomy; however, no larger studies have evaluated the impact of postoperative splinting. To compare the impact of night extension splinting on AROM, specifically extension, following needle aponeurotomy for Dupuytren contracture. A retrospective chart review was conducted in which the charts of 53 patients who underwent needle aponeurotomy for Dupuytren contracture between 2009 and 2013 were reviewed. The control group consisted of patients who underwent needle aponeurotomy only, whereas the treatment group was also referred for fabrication of custom night extension splints after surgery. Comparisons in pre- and postoperative AROM measurements for the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints were made between both groups of patients. The degrees of change in AROM for each joint were categorized in terms of levels of change: mild (0° to 29°); moderate (30° to 60°); and significant (≥61°). All patients exhibited increased AROM after surgery for both MCP and PIP joints. Both groups had a greater increase in AROM in the MCP joint. Twelve joints from the control group had moderate changes and two from the treatment group had significant changes. When both groups were compared, the levels of change of AROM between both groups did not vary significantly. Night extension splinting following needle aponeurotomy may not improve AROM of the MCP or PIP joints.

To compare the clinical outcomes and complication rates of patients undergoing simultaneous versus staged bilateral hip arthroscopy for bilateral symptomatic femoroacetabular impingement (FAI). Between 2010 and 2013, a total of 1,800 hip arthroscopy cases were retrospectively reviewed for cases of simultaneous bilateral hip arthroscopy. All patients with minimum 1-year follow-up were included. This group was matched 1:2 for age, sex, and alpha angle, to a control group of patients who underwent staged, bilateral procedures. Patient-reported outcome scores, including the Modified Harris Hip Score (mHHS), the Hip Outcome Score-Activity of Daily Living (HOS-ADL), and the Hip Outcome Score-Sport-Specific Subscale (HOS-SSS) were obtained preoperatively at 6 months and 1 and 2 years postoperatively. Eighty-one patients (162 hips) were identified who underwent bilateral hip arthroscopy for symptomatic FAI. Twelve patients (24 hips) who underwent simultaneous bilateral arthroscopy with minimum 1-year follow-up were compared with a matched cohort of 24 patients (48 hips) who underwent staged bilateral procedures. Mean preoperative alpha angle was 65.3° ± 9.6° in the simultaneous group and 65.9° ± 11.2° in the staged group (P = .6). At a mean follow-up of 17.8 months (range, 12 to 33 months), there were comparable improvements in simultaneous versus staged patient-reported outcome scores (mHHS 90.8 ± 11 v 88.9 ± 12.5, P = .662; HOS-ADL 97.3 ± 3.8 v 92.6 ± 10.3, P = .057; HOS-SSS 93.3 ± 10.2 v 86.5 ± 16.6, P = .203). The mean single anesthetic traction time was 90.8 ± 21.9 minutes (sum of both hips) in the simultaneous group, compared with a combined 2-anesthetic traction time of 85.7 ± 27.2 minutes in the staged group (P = .579). There were no traction-related complications in either group. No patients in the simultaneous group required revision surgery, whereas 1 patient in the staged group required lysis of adhesions at 24 months postoperatively. In a small sample, simultaneous bilateral hip arthroscopy is shown to be safe and effective, resulting in similar improvements in patient-reported outcomes at 1-year follow-up compared with staged bilateral procedures.

Abstract Background: Neoadjuvant radiotherapy in rectal cancer could interfere with anastomotic healing. We investigated the effects of preoperative oral administration of Benefiber on the healing irradiated colonic anastomosis. Methods: Forty male Wistar rats were divided into four groups. Group I (control group), Group II (Benefiber® pretreatment group), Group III (preoperative radiotherapy group) and Group IV (preoperative radiotherapy and Benefiber® pretreatment group). All animals underwent 1 cm left colon resection and primary anastomosis. On the 3rd and 7th postoperative days, all the rats were anesthetized to assess the anastomotic healing clinically, mechanically, histologically and biochemically. Results: The mean bursting pressure was significantly lower in-group III and significantly higher in-group II on day 7. The histologic parameters of anastomotic healing, such as epithelial regeneration and formation of granulation tissue, were significantly improved by use of preoperative Benefiber® on day 7. The amount of acid-soluble collagen concentrations significantly increased in-group IV compared to group III on day 3. The amount of salt-soluble collagen concentrations significantly increased in group II compared to group III on day 3. Conclusions: Colonic anastomotic healing can be adversely affected by preoperative radiotherapy, but orogastric feeding with Benefiber may improve the healing process.

The aim of this study was to verify the efficacy of a manualized, cognitively oriented psychological intervention, called Mental Fitness, in improving the mental and physical health of patients with acute coronary syndrome (ACS). Mental Fitness is a small-group four-session treatment aimed at increasing awareness of one's own bodily perceptions, emotions, and thoughts and is overall tailored on participants' perception of control over their health. Prospective randomized controlled single-blind trial. Patients with ACS were recruited within a week from their acute cardiac event. Patients in the intervention group underwent one of two variants of Mental Fitness, depending on their perceived (internal or external) control over their health. Patients in the control group underwent standard treatment. All the patients were submitted to a clinical and psychological follow-up for 8 months. The patients who underwent the Mental Fitness intervention (N = 31) showed, compared to the control patients (N = 34), increased quality of life in its physical, psychological, social and environmental domains, more functional emotional and problem-centred coping strategies, and higher emotional awareness. They also showed improved high-density lipoprotein cholesterol, triglycerides, heart rate, and left ventricular ejection fraction compared to the controls. In addition, they were more successful in maintaining physical exercise. This study demonstrates the efficacy of Mental Fitness in modifying specific psychological and physical variables conditioning cardiological patients' prognosis. It also confirms the importance of differentiating psychological interventions based on the psychological characteristics of the patients. Statement of contribution What is already known on this subject? Traditional symptom-based interventions in heart disease are aimed at diagnosing and reducing psychological symptomatology (e.g., depression), but recent work has shown the usefulness of orienting psychological interventions to patients' representations of themselves and of the world and to how such representations influence their thoughts, feelings, and behaviours (e.g., Chiavarino et al., ). What does this study add? Mental Fitness, by working on awareness of bodily perceptions, emotions, and thoughts, leads to positive changes in physical and psychological health. Mental Fitness is a cost-effective psychological intervention that adds significantly to the effectiveness of standard medical care. © 2016 The British Psychological Society.

Learned fear is crucial in the development and maintenance of posttraumatic stress disorder (PTSD) and other anxiety disorders, and extinction of learned fear is necessary for response to exposure-based treatments. In humans, research suggests disrupted sleep impairs consolidation of extinction, though no studies have examined this experimentally using total sleep deprivation. Seventy-one healthy controls underwent a paradigm to acquire conditioned fear to a visual cue. Twenty-four hours after fear conditioning, participants underwent extinction learning. Twenty-four hours after extinction learning, participants underwent extinction recall. Participants were randomized to three groups: 1) well-rested throughout testing ("normal sleep"; n = 21); 2) 36 hours total sleep deprivation before extinction learning ("pre-extinction deprivation"; n = 25); or 3) 36 hours total sleep deprivation after extinction learning and before extinction recall ("post-extinction deprivation"; n = 25). The groups were compared on blink EMG reactivity to the condition stimulus during extinction learning and recall. There were no differences among the three groups during extinction learning. During extinction recall, the pre-extinction deprivation group demonstrated significantly less extinction recall than the normal sleep group. There was no significant difference between the normal sleep and post-extinction deprivation group during extinction recall. Results indicated sleep deprivation prior to extinction training significantly disrupts extinction recall. These findings suggest that (1) sleep deprivation in the immediate aftermath of trauma could be a potential contributor to PTSD development and maintenance via interference with natural extinction processes and (2) management of sleep symptoms should be considered during extinction-based therapy.

Perianal Crohn's disease (PCD) can affect both quality of life and psychological wellbeing. A subset of pediatric patients with complex PCD require surgical intervention, although appropriate timing and treatment regimens remain unclear. This study aimed to describe a large pediatric cohort in a tertiary center to determine the range of surgical management in children with complex PCD. A retrospective review of children requiring operative intervention for PCD over 13 years (2002-2014) was performed. PCD was divided into simple and complex based on the type of surgical procedure, and the two groups were compared. The 57 children were divided into two groups: the simple group (N=43) underwent abscess drainage ± seton insertion alone, and the complex group (N=14) underwent loop ileostomy ± more extensive surgery. In the complex group, females were more predominant (57% of complex vs 30% of simple), and the average age at diagnosis was lower. Anti-TNF therapy was utilized in 79.1% of simple and 100% of complex PCD. All 14 complex patients underwent a defunctioning ileostomy, with 7 requiring further operations (subtotal colectomy=4, proctocolectomy ± anal sparing=5, plastic surgery reconstruction with perineal flap/graft=4). Complex PCD represents a small but challenging subset of patients in which major surgical intervention may be necessary to alleviate the symptoms of this debilitating condition. retrospective case study with no control group - level IV.

The aim of this study was to investigate the influence of a history of diabetes mellitus (DM) and the glycated hemoglobin (HbA1c) level on the survival in patients who underwent complete resection for non-small cell lung cancer (NSCLC). Of the patients who underwent complete resection for NSCLC between 2007 and 2015, 468 were classified into DM (who were currently taking medication for DM) and no DM groups as well as into high HbA1c (≥ 6.5) and normal HbA1c (< 6.5) groups. The overall survival (OS) did not differ significantly between either pair of groups. Among the elderly patients, the OS did not differ significantly between the DM and no DM groups, but was significantly higher in the normal-HbA1c group than in the high-HbA1c group (5-year survival rate: 84.7 versus 37.2%, respectively, p < 0.01). In the elderly patients, non-adenocarcinoma histology, advanced stage, a high Charlson comorbidity index, and a high preoperative HbA1c level were found to be independent risk factors for the OS. We revealed that a high preoperative HbA1c level was associated with a poor OS in elderly patients who underwent complete resection for NSCLC. This suggests that it is necessary to achieve diabetic control prior to complete resection in NSCLC patients.

Breast ptosis may be caused by several factors, including significant weight loss, pregnancy, long breastfeeding periods, and involution of the postmenopausal breast tissue. The authors performed a prospective study to evaluate patient satisfaction and the rate of complications after modified round block mastopexy versus traditional round block mastopexy. Forty-four patients fulfilled the inclusion criteria for undergoing round block mastopexy in a prospective randomized controlled study performed from 2007 to 2008. All the patients received polyurethane silicone implants. Group A included patients who underwent the traditional round block technique described by Benelli. Group B included patients who underwent the traditional round block and 4 cardinal glando-glandular permanent sutures. The overall satisfaction with body appearance after breast mastopexy was rated on a scale of 1 (poor), 2 (fair), 3 (good), 4 (very good), and 5 (excellent). Group A patient ages ranged from 28 to 52 years and in Group B ranged from 29 to 49 years. The mean implant volume was 215 cc in both Groups. The complication and satisfaction rates for both Groups are reported. The combination of the cardinal glandulo-glandular sutures along with the traditional round block appears to be key to preventing the areolar enlargement and persistent breast ptosis. The satisfaction rates in patients who underwent the modified round mastopexy appear superior when compared to the traditional round block mastopexy. Furhter long-term follow-up need to be performed in order to confirm the favorable results seen in this series of cases.

Bilateral sacrospinous fixation with tailored mesh arms (bSSVF) uses polypropylene mesh to suspend the vault to the sacrospinous ligaments bilaterally with minimal tension, recreating nulliparous midline anatomy. It can be used with uterine conservation. Our primary objective was to determine objective cure rate at one year following bSSVF compared with a control group undergoing abdominal sacrocolpopexy (ASC). Secondary objectives were to compare symptoms, quality of life, sexual function, pain, and global satisfaction before and after surgery and between bSSVF and ASC groups at one year. This prospective cohort study enrolled patients with symptomatic prolapse who chose to undergo bSSVF or ASC. Baseline demographics were obtained. Prolapse quantification, validated symptom questionnaire scores, and McGill pain scores were obtained at baseline, six weeks, and one-year postoperatively. Global satisfaction was recorded. The primary outcome measure was the difference in cure rate (vault stage ≤ 1) between groups. Fifty patients were recruited: 30 underwent bSSVF and 17 ASC. Forty-three patients were available for one-year follow-up. Baseline data were similar. There was no difference in vault stage between bSSVF and ASC groups at one year. Five women who underwent bSSVF had cervical elongation, and four of these were classified as POP recurrence. Women who underwent bSSVF had more anterior recurrences but fewer postoperative complications, shorter hospital stay, and less use of narcotics than controls. Questionnaire scores were similar at one year. All respondents felt subjective improvement after either surgical procedure. Objective and subjective cure rates are comparable after bSSVF and ASC. Hysteropexy may cause cervical elongation that merits further research.

To compare the length of the membranous (functional) urethra in male patients who underwent the male transobturator sling (TOS) for postradical prostatectomy urinary incontinence (PPI). The TOS is in established use for treatment of PPI; however, the precise mechanism of action is unknown. This is a prospective case-controlled study on men undergoing male TOS surgery from 2008 to 2014. The comparison arm included patients without incontinence after radical prostatectomy. All participants underwent dynamic magnetic resonance imaging (MRI) at baseline and this was repeated after TOS placement for those who underwent the procedure. Three standardized points were measured using MRI and compared in both groups in addition to clinical measures. Thirty-nine patients were enrolled and 31 patients completed the protocols. The controls (N = 14) had a longer vesicourethral anastomosis to urethra measured at the penile bulb (functional urethral length) distance compared to the pre-TOS group at rest (1.92 cm controls vs 1.27 cm pre-TOS, P = .0018) and at Valsalva (2.13 cm controls vs 1.72 cm pre-TOS, P = .0371). Placement of the sling (N = 17) increased the functional urethral length distance at rest (1.92 cm control vs 1.53 cm post-TOS, P = .09) and at Valsalva (1.94 cm post-TOS vs 2.13 cm control, P = .61), so that the difference was no longer statistically significant. We identified that one possible mechanism in improvement in stress urinary incontinence post-TOS placement is the lengthening of the vesicourethral anastomosis to bulbar-urethra distance. This is the first such study utilizing dynamics MRI in post prostatectomy controls, incontinent pre-TOS, and post-TOS to assess and show these findings. Copyright © 2018 Elsevier Inc.

Breast cancer (BC) and/or its treatments may affect sexual functioning based on physiological and psychosocial mechanisms. The aim of this study was to prospectively investigate sexual adjustment of BC patients during a follow-up period of one year after mastectomy (ME) or breast conserving therapy (BCT). In this prospective controlled study, women with BC and an age-matched control group of healthy women completed the Beck Depression Inventory Scale, World Health Organization 5 Well-being scale, Body Image Scale, EORTC QLQ questionnaire, Dyadic Adjustment Scale, Short Sexual Functioning Scale and Specific Sexual Problems Questionnaire to assess various aspects of sexual and psychosocial functioning before surgery, six months and one year after surgical treatment. In total, 149 women with BC and 149 age-matched healthy controls completed the survey. Compared to the situation before surgery, significantly more BCT women reported problems with sexual arousal six months after surgery and significantly more women of the ME group reported problems with sexual desire, arousal and the ability to achieve an orgasm six months and one year after surgery. While in comparison with healthy controls, no significant differences in sexual functioning were found after BCT surgery, significantly more women who underwent ME reported problems with sexual desire, arousal, the ability to achieve an orgasm and intensity of the orgasm. Although little differences were seen in sexual functioning in the BCT group during prospective analyses and in comparison with healthy controls, analyses revealed that women who underwent a ME were at risk for post-operative sexual dysfunctions.

Hepatic injury caused by ischemia/reperfusion (I/R) is a clinical problem associated with major liver surgery. Among other flavonoids, apigenin has shown a promising effect on I/R cases. In this study, we have investigated the effects of apigenin after liver I/R injury in rats. Forty eight rats were randomized into the following eight groups: (1) Control-sham group: rats subjected to the surgical procedure, except for liver I/R; (2) DMSO group: rats subjected to surgery, except for liver I/R given the apigenin solvent dimethyl-sulfoxide intraperitoneally; (3) C60 group; (4) C120 group; (5) C240 group: rats underwent liver ischemia for 45 min followed by reperfusion for 60 min, 120 min, and 240 min; (6) AP60 group; (7) AP120 group; (8) AP240 group: rats underwent liver ischemia for 45 min, and then given apigenin (5 mg) intraperitoneally followed by reperfusion for 60 min, 120 min, and 240 min. Reverse transcription polymerase chain reaction was performed on liver tissues to measure BCL-2/BAX expression, enzyme-linked immunosorbent assay to measure M30/M65 and ICAM-1. Immunohistochemistry was used to identify M30 biomarker in liver tissues. Quantitative variables were tested by Kolmogorov-Smirnov test, repeated measures analysis of variance/Friedman test. Gene levels were assessed by Student's t-test/Mann-Whitney U-test. BCL-2 levels were significantly higher in I/R apigenin groups than in I/R control groups. BAX levels were lower in the AP240 group than in C240 group. Prolongation of reperfusion resulted in increased activation of M30. ICAM-1 levels were lower in the AP240 group than in C240 group. Apigenin seems to inhibit the process of apoptosis and ameliorate the hepatic I/R injury.

To introduce the surgery method to reset and fix tibial plateau fracture without opening joint capsule, and evaluate the safety and effectiveness of this method. Between July 2011 and July 2013, 51 patients with tibial plateau fracture accorded with the inclusion criteria were included. All of 51 patients, 17 cases underwent open reduction and internal fixation without opening joint capsule in trial group, and 34 cases underwent traditional surgery method in control group. There was no significant difference in gender, age, cause of injury, time from injury to admission, side of injury, and types of fracture between 2 groups (P > 0.05). The operation time, intraoperative blood loss, incision length, incision healing, and fracture healing were compared between 2 groups. The tibial-femoral angle and collapse of joint surface were measured on X-ray film. At last follow-up, joint function was evaluated with Hospital for Special Surgery (HSS) knee function scale. The intraoperative blood loss in trial group was significantly less than that in control group (P < 0.05). The incision length in trial group was significantly shorter than that in control group (P < 0.05). Difference was not significant in operation time and the rate of incision healing between 2 groups (P > 0.05). The patients were followed up 12-30 months (mean, 20.4 months) in trial group and 12-31 months (mean, 18.2 months) in control group. X-ray films indicated that all cases in 2 groups obtained fracture healing; there was no significant difference in the fracture healing time between 2 groups (t=1.382, P=0.173). On X-ray films, difference was not significant in tibial-femoral angle and collapse of joint surface between 2 groups (P > 0.05). HSS score of the knee in trial group was significantly higher than that of control group (t=3.161, P=0.003). It can reduce the intraoperative blood loss and shorten the incision length to use open reduction and internal fixation without opening joint capsule for tibial plateau fracture. Traction of joint capsule is helpful in the reduction and good recovery of joint surface collapse. In addition, the surgery without opening joint capsule can avoid joint stiffness and obtain better joint function.

To evaluate the correlation between the use of aerosol therapy in early childhood and the presence of Molar Incisor Hypomineralisation (MIH). a retrospective case-control study in which a group (cases) consisted of children from 6 to 13 years with MIH visited at the unit of Pediatric Dentistry of the Policlinico Tor Vergata (Rome, Italy), and a group (controls) consisted of an equal number of children of the same age without MIH. Data about the aerosol therapy and the presence of MIH were obtained respectively by medical history and intraoral clinical examination. Collected data underwent statistical analysis using mainly non-parametric tests (p < 0.05). In the study were included 182 patients, of which 91 (46 males, 51%) were children with MIH (cases), and 91 (46 males, 51%) were children without MIH (controls). In the group of patients with MIH, in the early childhood, 12 (13.1%) never had aerosol therapy, 6 (6.6%) underwent aerosol therapy less than 7 days per year, 22 (24.2%) from 8 to 15 days per year, 22 (24.2%) from 16 to 45 days a year, and 29 (31.9%) more than 45 days per year. In the control group, in the early childhood, 9 (9.9%) never had aerosol therapy, 29 (31.9%) underwent aerosol therapy less than 7 days per year, 26 (28.6%) from 8 to 15 days per year, 20 (22.0%) from 16 to 45 days a year and 7 (7.6%) more than 45 days per year. the risk of developing MIH in children undergoing intensive use of aerosol therapy with respect to those receiving a less intensive use resulted in an odds ratio of 3.19 (p <0.001) in the general population, 4.83 (p < 0.001) in males and was not statistically significant in females (p = 0.132). The Spearman correlation between aerosol therapy and MIH was 0.278 (p < 0.001) in the general population, 0.372 (p < 0.001) in male, and it was not statistically significant (p = 0.08) in female subjects. Aerosol therapy carried out in early childhood appears to be a risk factor for the development of MIH, particularly in male subjects.

BACKGROUND: Bibliotherapy is defined as using dynamic interaction along with reading a book in order to help the people to increase their cognitive understanding. This study aims to investigate the effect of bibliotherapy on the psychological capital of the employees of the Department of Management and Medical Informatics of Isfahan University of Medical Science. MATERIALS AND METHODS: This is an applied study using a semi-empirical method. The statistical population consists of all nonfaculty employees of the target department (70 people). Twenty eight people were randomly selected and divided into experiment and control groups and answered the psychological capital questionnaire. The data gathering tool was the psychological capital questionnaire of Luthans. The experiment group underwent six 2-h sessions of bibliotherapy where the control group underwent no interference. Both groups answered the questionnaire again 1-month after the final bibliotherapy session. The information was analyzed using descriptive (average and frequency distribution) and analytical (independent t-test, paired t-test, Chi-square test, and Mann–Whitney U-test) with the help of SPSS 20 software. RESULTS: The findings showed no meaningful distinction average scores of the physiological capital of both groups before interference. However, the average physiological capital score and an average score of each factor in the experiment group was meaningfully higher than that of the control group after the bibliotherapy sections. CONCLUSION: The results showed that bibliotherapy is a suitable method for increasing the psychological capital of the employees of different organizations which will in turn provide both the employees themselves and the organization with material and spiritual gains.

Several prospective studies into the effects of adjuvant systemic therapy on cognitive functioning suggest that a proportion of breast cancer patients show cognitive deficits already before the start of systemic therapy. Owing to, among others, methodological inconsistency, studies report different rates of this pre-treatment cognitive impairment. We examined the impact of four different criteria of cognitive impairment and two types of reference groups (a study-specific healthy reference group versus published normative data) on the prevalence of cognitive impairment. Two hundred and five postmenopausal breast cancer patients underwent a battery of neuropsychological tests before the start of endocrine therapy, 124 healthy subjects underwent the same tests. Proportions of cognitive impaired patients were calculated for each of four criteria for cognitive impairment, using (1) study-specific healthy controls and (2) published norms of healthy controls as reference groups. The prevalence of cognitive impairment varied greatly with the strictness of the criterion, as expected, but also was dependent on the reference group used. Cognitive impairment, relative to published norms, ranged from 1% for the strictest to 36.6% for the less strict criterion, cognitive impairment relative to study-specific healthy controls, ranged from 13.7 to 45.4% for the same criteria. This study highlights contrasting proportions of cognitive impairment by using different criteria for cognitive impairment and different reference groups. (Dis)advantages of the methods using a criterion for cognitive impairment, and of the use of published norms versus a study-specific reference group are discussed.

The aim of the present study was to investigate the effect of hyperbaric oxygen (HBO) on lipid peroxidation and visual development in a neonatal rat model of hypoxic-ischemic brain damage (HIBD). The rat models of HIBD were established by delayed uterus dissection and were divided randomly into two groups (10 rats each): HIBD and HBO-treated HIBD (HIBD+HBO) group. Another 20 rats that underwent sham-surgery were also divided randomly into the HBO-treated and control groups. The rats that underwent HBO treatment received HBO (0.02 MPa, 1 h/day) 24 h after the surgery and this continued for 14 days. When rats were 4 weeks old, their flash visual evoked potentials (F-VEPs) were monitored and the ultrastructures of the hippocampus were observed under transmission electron microscope. The levels of superoxide dismutase (SOD) and malonyldialdehyde (MDA) in the brain tissue homogenate were detected by xanthine oxidase and the thiobarbituric acid colorimetric method. Compared with the control group, the ultrastructures of the pyramidal neurons in the hippocampal CA3 area were distorted, the latencies of F-VEPs were prolonged (P<0.01) and the SOD activities were lower while the MDA levels were higher (P<0.01) in the HIBD group. No significant differences in ultrastructure, the latency of F-VEPs or SOD/MDA levels were identified between the HBO-treated HIBD group and the normal control group (P>0.05). HBO enhances antioxidant capacity and reduces the ultrastructural damage induced by hypoxic-ischemia, which may improve synaptic reconstruction and alleviate immature brain damage to promote the habilitation of brain function.

Frontal lobe epilepsy (FLE) is the second most frequent type of localization-related epilepsy, and it may impact neurocognitive functioning with high variability. The prevalence of neurocognitive impairment in affected children remains poorly defined. This report outlines the neuropsychological profiles and outcomes in children with new onset FLE, and the impact of epilepsy-related factors, such as seizure frequency and antiepileptic drug (AED) load, on the neurocognitive development. Twenty-three consecutive children (15 males and 8 females) with newly diagnosed cryptogenic FLE were enrolled; median age at epilepsy onset was 7 years (6-9.6 years). They underwent clinical and laboratory evaluation and neuropsychological assessment before starting AED treatment (time 0) and after one year of treatment (time 1). Twenty age-matched patients affected by idiopathic generalized epilepsy (10 male and 10 females) and eighteen age-matched healthy subjects (9 males and 9 females) were enrolled as controls and underwent the same assessment. All patients with FLE showed a significant difference in almost all assessed cognitive domains compared with controls, mainly in frontal functions and memory. At time 1, patients were divided into two groups according to epilepsy-related factors: group 1 (9 patients) with persisting seizures despite AED polytherapy, and group 2 (14 patients) with good seizure control in monotherapy. A significant difference was highlighted in almost all subtests in group 1 compared with group 2, both at time 0 and at time 1. In children with FLE showing a broad range of neurocognitive impairments, the epilepsy-related factors mostly related to a worse neurocognitive outcome are poor seizure control and the use of AED polytherapy, suggesting that epileptic discharges may have a negative impact on the functioning of the involved cerebral regions.

Developing a one-second automatic glaucoma treatment using trans-scleral laser trabeculoplasty (LTP) without a gonioscopy lens Purpose: Developing an LTP device for delivering multiple simultaneous trans-scleral applications of low energy laser irradiation to the trabecular meshwork (TM) for reducing Intraocular Pressure (IOP). Methods: Concept proof: A randomized, masked, controlled one was performed on open angle glaucoma patients. The control group underwent conventional SLT (100 laser spots through a gonioscope for 360 degrees directly on the TM). The trial group underwent irradiation by the same laser at the same irradiation parameters on the sclera overlying the TM. Topical glaucoma therapy was not changed during the 12 months trial. Feasibility trial: Using optimized laser parameters, 60 discrete applications were administered on similar locations of patients' sclera. Results: Concept proof: Trans-scleral applications: (N=15), IOP decrease from 20.21 mmHg before treatment to 16.00 (27.1%) at one year. The corresponding numbers for the control group (n=15), were 21.14 mmHg and 14.30 (23.4%). There was no statistical difference between the two groups in IOP reduction. The complications rate was significantly higher in the control group. Trial 2: IOP was reduced from an of 25.3 mmHg to 19.3 (23.7%) in the 11 patients. Conclusions: Laser coherency, lost in tissue transmission, is not required for the therapeutic effect. The new method will possibly enable treatment of angle closure glaucoma as well as simultaneous applications of all laser spots to the sclera. When used conjointly with target acquisition, will make feasible an automatic glaucoma treatment in less than one second.

Extensive excision of the esophageal mucosa by endoscopic submucosal dissection (ESD) frequently evokes a luminal stricture. This study aimed to determine the efficacy of a high-density collagen patch for the prevention of esophageal stricture in extensive ESD. Six pigs underwent circumferential esophageal ESD under general anesthesia. In 3 pigs, artificial ulcers were covered by 2 collagen patches. The other 3 pigs underwent circumferential ESD only. The 2 collagen patches were settled onto the ulcer surface using a general endoscope and instruments. The collagen patch-treated group showed significantly better patency rates on both the oral and anal sides of the wound area compared with the control group at day 14. The mucosal re-epithelization ratio was significantly promoted, and the extent of mucosal inflammation and fibrosis was significantly decreased with the collagen patch treatment in the wound area. The frequency of cells positive α-smooth muscle actin was significantly reduced in the collagen patch-treated group compared with the control group. We have established a high-density collagen device that can reduce the esophageal stricture associated with extensive ESD. This easy-to-handle device would be useful during superficial esophageal cancer treatment by ESD. Copyright © 2017 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

To evaluate the efficacy and safety of external cephalic version (ECV) among women with previous cesarean delivery. A retrospective study was conducted using data for women with previous cesarean delivery and breech presentation who underwent ECV at or after 36 weeks of pregnancy during 2011-2016. For every case, two multiparous women without previous cesarean delivery who underwent ECV and were matched for age and pregnancy duration were included. Characteristics and outcomes were compared between groups. ECV was successful for 32 (84.2%) of 38 women with previous cesarean delivery and 62 (81.6%) in the control group (P=0.728). Multivariate regression analysis confirmed that previous cesarean was not associated with ECV success (odds ratio 1.89, 95% confidence interval 0.19-18.47; P=0.244). Successful vaginal delivery after successful ECV was reported for 19 (59.4%) women in the previous cesarean delivery group and 52 (83.9%) in the control group (P<0.001). No ECV-associated complications occurred in women with previous cesarean delivery. To avoid a repeat cesarean delivery, ECV can be offered to women with breech presentation and previous cesarean delivery who are otherwise eligible for a trial of labor. © 2017 International Federation of Gynecology and Obstetrics.

To describe the use of intrauterine inflated Foley's catheter balloon for control of postpartum hemorrhage (PPH) during cesarean section (CS) in cases of abnormally invasive placenta previa aiming to preserve the uterus. Retrospective case-control study of the data of women who underwent elective CS on abnormally adherent placenta previa was carried out. Women in whom inflated Foley's catheter balloon was used for control of PPH during CS ( n  = 40) were compared with a control group of women who underwent elective CS by the same technique but without use of intrauterine catheter balloon ( n  = 38). Use of intrauterine inflated Foley's catheter balloon significantly reduced the estimated amount of blood loss ( P  = 0.008), amounts of crystalloids, colloids and packed red blood cells transfusion ( P  = 0.025, 0.017 and 0.022, respectively), and the need for bilateral internal iliac artery (IIA) ligation ( P  = 0.016). No significant difference was observed between both groups regarding the use of massive transfusion protocol, performing cesarean hysterectomy, relaparotomy, and admission to the intensive care unit. Application of an intrauterine inflated Foley's catheter balloon during CS in cases of morbidly adherent placenta previa helps to control PPH with preservation of the uterus and decreases the need for the invasive IIA ligation.

Analyse the effect of core stability exercises in addition to conventional physiotherapy training three months after the intervention ended. A randomized controlled trial. Outpatient services. Seventy-nine stroke survivors. In the intervention period, both groups underwent conventional physiotherapy performed five days/week for five weeks, and in addition the experimental group performed core stability exercises for 15 minutes/day. Afterwards, during a three-month follow-up period, both groups underwent usual care that could eventually include conventional physiotherapy or physical exercise but not in a controlled condition. Primary outcome was trunk control and dynamic sitting balance assessed by the Spanish-Version of Trunk Impairment Scale 2.0 and Function in Sitting Test. Secondary outcomes were standing balance and gait evaluated by the Berg Balance Scale, Tinetti Test, Brunel Balance Assessment, Spanish-Version of Postural Assessment Scale for Stroke and activities of daily living using the Barthel Index. A total of 68 subjects out of 79 completed the three-month follow-up period. The mean difference (SD) between groups was 0.78 (1.51) points ( p = 0.003) for total score on the Spanish-Version of Trunk Impairment Scale 2.0, 2.52 (6.46) points ( p = 0.009) for Function in Sitting Test, dynamic standing balance was 3.30 (9.21) points ( p= 0.009) on the Berg Balance Scale, gait was 0.82 (1.88) points ( p = 0.002) by Brunel Balance Assessment (stepping), and 1.11 (2.94) points ( p = 0.044) by Tinetti Test (gait), all in favour of core stability exercises. Core stability exercises plus conventional physiotherapy have a positive long-term effect on improving dynamic sitting and standing balance and gait in post-stroke patients.

The impact of verbal communication on laparoscopic team performance was examined. A total of 24 dyad teams, comprised of residents, medical students, and office staff, underwent 2 team tasks using a previously validated bench model. Twelve teams (feedback groups) received instant verbal instruction and feedback on their performance from an instructor which was compared with 12 teams (control groups) with minimal or no verbal feedback. Their performances were both video and audio taped for analysis. Surgical backgrounds were similar between feedback and control groups. Teams with more verbal feedback achieved significantly better task performance (P = .002) compared with the control group with less feedback. Impact of verbal feedback was more pronounced for tasks requiring team cooperation (aiming and navigation) than tasks depending on individual skills (knotting). Verbal communication, especially the instructions and feedback from an experienced instructor, improved team efficiency and performance.

The aim of the study was to assess solid phase gastric emptying via non-invasive 13C-sodium acetate breath test in large breed dogs with or without gastric dilatation-volvulus (GDV). Dogs were recruited into one of the following groups: group 1 = healthy large breed dogs with no history of GDV, group 2 = dogs that underwent elective abdominal surgery for reasons unrelated to the gastrointestinal tract, and group 3 = dogs that underwent laparotomy and gastropexy to correct GDV. The dogs were fed a test meal containing 100 mg 13C-sodium acetate (for group 2 and 3, this was < 48 hours post-operatively). Breath samples were obtained at baseline and every 30 minutes for 3 hours, then every hour for a total of 7 hours. 12CO2/13CO2 ratio was measured for each breath sample via non-dispersive infrared spectroscopy and 25%, 50% and 75% gastric emptying times were calculated and compared between groups. Gastric emptying times were significantly prolonged in dogs undergoing surgery (group 2) compared to group 1 and 3. Also, gastric emptying times of dogs with GDV were significantly prolonged compared to controls, but not to the same extent as dogs in group 2. There was a significant effect of abdominal surgery on gastric emptying times. Surprisingly, dogs after GDV surgery and gastropexy had shorter gastric emptying times than dogs undergoing laparotomy for reasons other than GDV, but still prolonged compared to healthy controls. The reason for these differences requires further study.

Background. Dentists' awareness of the effects of bleaching agents on the surface and mechanical properties of restorative materials is of utmost importance. Therefore, this in vitro study was undertaken to investigate the effects of different bleaching strategies on the microhardness of a silorane-based composite resin. Methods. Eighty samples of a silorane-based composite resin (measuring 4 mm in diameter and 2 mm in thickness) were prepared within acrylic molds. The samples were polished and randomly assigned to 4 groups (n=20). Group 1 (controls) were stored in distilled water for 2 weeks. The samples in group 2 underwent a bleaching procedure with 15% carbamide peroxide for two weeks two hours daily. The samples in group 3 were bleached with 35% hydrogen peroxide twice 5 days apart for 30 minutes each time. The samples in group 4 underwent a bleaching procedure with light-activated 35% hydrogen peroxide under LED light once for 40 minutes. Then the microhardness of the samples was determined using Vickers method. Data were analyzed with one-way ANOVA and post hoc Tukey tests (P < 0.05). Results. All the bleaching agents significantly decreased microhardness compared to the control group (P < 0.05). In addition, there were significant differences in microhardness between groups 2 and 4 (P = 0.001) and between groups 3 and 4 (P<0.001). However, no significant differences were detected in microhardness between groups 2 and 3 (P > 0.05). Conclusion. Bleaching agents decreased microhardness of silorane-based composite resin restorations, the magnitude of which depending on the bleaching strategy used.

We evaluated 22 measures of cortical folding, 20 derived from local curvature (curvature-based measures) and two based on other features (sulcal depth and gyrification index), for their capacity to distinguish between normal and aberrant cortical development. Cortical surfaces were reconstructed from 12 term-born control and 63 prematurely-born infants. Preterm infants underwent 2-4 MR imaging sessions between 27 and 42weeks postmenstrual age (PMA). Term infants underwent a single MR imaging session during the first postnatal week. Preterm infants were divided into two groups. One group (38 infants) had no/minimal abnormalities on qualitative assessment of conventional MR images. The second group (25 infants) consisted of infants with injury on conventional MRI at term equivalent PMA. For both preterm infant groups, all folding measures increased or decreased monotonically with increasing PMA, but only sulcal depth and gyrification index differentiated preterm infants with brain injury from those without. We also compared scans obtained at term equivalent PMA (36-42weeks) for all three groups. No curvature-based measured distinguished between the groups, whereas sulcal depth distinguished term control from injured preterm infants and gyrification index distinguished all three groups. When incorporating total cerebral volume into the statistical model, sulcal depth no longer distinguished between the groups, though gyrification index distinguished between all three groups and positive shape index distinguished between the term control and uninjured preterm groups. We also analyzed folding measures averaged over brain lobes separately. These results demonstrated similar patterns to those obtained from the whole brain analyses. Overall, though the curvature-based measures changed during this period of rapid cerebral development, they were not sensitive for detecting the differences in folding associated with brain injury and/or preterm birth. In contrast, gyrification index was effective in differentiating these groups. Copyright © 2015 Elsevier Inc. All rights reserved.

[Purpose] This study aims to identify the effect of respiratory exercise on trunk control, pulmonary function, and trunk muscle activity in chronic stroke patients. [Subjects and Methods] The study included 24 chronic stroke patients who were randomly assigned, 12 each, to the experimental and control groups, and received neurodevelopmental treatment. Moreover, the experimental group underwent respiratory exercise. In each patient, the trunk control was measured using the Trunk Impairment Scale (TIS); muscle activity of the trunk, through the surface electromyogram; and pulmonary function, using the pneumatometer. [Results] The intragroup comparison showed significant differences in TIS, Forced vital capacity (FVC), Forced expiratory volume at one second (FEV1), Rectus Abdominis (RA), Internal Oblique (IO) and External Oblique (EO) in the experimental group. The intergroup comparison showed that the differences in TIS, FVC, FEV1, RA, IO and EO within the experimental group appeared significant relative to the control group. [Conclusion] Based on these results, this study proved that respiratory exercise was effective in improving trunk control, pulmonary function, and trunk muscle activity in patients with chronic stroke.

Although rotator cuff (RC) tendinopathy is a frequent pathology of the shoulder, the real understanding of its aetiopathogenesis is still unclear. Several studies showed that RC tendinopathy is more frequent in patients with hyperglycemia, diabetes, obesity, or metabolic syndrome. This paper aims to evaluate the serum concentration of fibrinogen in patients with RC tears. Metabolic disorders have been related to high concentration of serum fibrinogen and the activity of fibrinogen has been proven to be crucial in the development of microvascular damage. Thus, it may produce progression of RC degeneration by reducing the vascular supply of tendons. We report the results of a cross-sectional frequency-matched case-control study comparing the serum concentration of fibrinogen of patients with RC tears with that of a control group of patients without history of RC tears who underwent arthroscopic meniscectomy. We choose to enrol in the control group patients with pathology of the lower limb with a likely mechanic, not metabolic, cause, different from tendon pathology. We found no statistically significant differences in serum concentration of fibrinogen when comparing patients with RC tears and patients who underwent arthroscopic meniscectomy (P = 0.5). Further studies are necessary to clarify the role of fibrinogen in RC disease.

Behavioral economic approaches could increase uptake for colorectal cancer screening. We performed a randomized controlled trial of 2245 employees to determine whether an email containing a phone number for scheduling (control), an email with the active choice to opt in or opt out (active choice), or the active choice email plus a $100 incentive (financial incentive) increased colonoscopy completion within 3 months. Higher proportions of participants in the financial incentive group underwent screening (3.7%) than in the control (1.6%) or active choice groups (1.5%) (P = .01 and P < .01). We found no difference in uptake of screening between the active choice and control groups (P = .88). The $100 conditional incentive modestly but significantly increased colonoscopy use.

Bernese (Ganz) periacetabular osteotomy is associated with significant blood loss and the need for perioperative transfusion. Tranexamic acid decreases blood loss and minimizes transfusion rates in total joint arthroplasty. However, no reports have described its use in patients undergoing Bernese periacetabular osteotomy. This study reports the use of intravenous tranexamic acid in these patients. The study included 137 patients (150 hips) who underwent isolated periacetabular osteotomy at a single institution between 2003 and 2014. Of these, 68 patients (75 hips) received intravenous tranexamic acid 1 g at the time of incision and 1 g at the time of closure. A group of 69 patients (75 hips) served as control subjects who underwent periacetabular osteotomy without administration of intravenous tranexamic acid. Thromboembolic disease was defined as deep venous thrombosis or pulmonary embolism occurring within 6 weeks of surgery. Outcomes measured included transfusion requirements, pre- and postoperative hemoglobin values, operative times, and thromboembolic disease rates. Aspirin was used as the thromboembolic prophylactic regimen in 95% of patients. The rate of allogeneic transfusion was 0 in the tranexamic acid group compared with 21% in the control group (P=.0001). No significant difference was found in the autologous cell salvage requirement (.96 vs 1.01; P=.43) or the thromboembolic disease rate between the tranexamic acid group and the control group (2.67% vs 1.33%; P=.31). The use of intravenous tranexamic acid led to a decreased transfusion requirement with no increased risk of thromboembolic disease in this contemporary cohort of patients undergoing periacetabular osteotomy.

Peroral endoscopic myotomy (POEM) has been developed to treat achalasia as a novel less invasive modality. We aimed to compare the efficacy and safety of conventional knife versus Hybrid knife (HK) during POEM procedure. Between June 2012 and July 2014, 31 patients underwent POEM using HK in our department (HK group), and 36 patients underwent POEM using conventional method (injection needle and triangular tip [TT] knife, TT group). Procedure-related parameters, symptom relief, adverse events were compared between two groups. There were no significant differences in the age, sex and other baseline characteristics between the two groups. The mean procedural time was significantly shorter in HK group than TT group (53.0 ± 17.2 vs. 67.6 ± 28.4 min, p = 0.015). The mean frequency of devices exchange was 4.7 ± 1.7 in HK group and 10.9 ± 1.8 in TT group (p = 0.000). No serious adverse events occurred postoperatively in both groups. At one-year follow-up, a total of 94% treatment success was achieved in all patients (93.5% in HK group and 94.4% in TT group, p = 0.877). HK in POEM can shorten the procedural time, and achieve similar treatment success compared to conventional TT knife.

It is believed that patients who undergo thyroidectomy for Graves' disease are more likely to experience postoperative hypocalcemia than patients undergoing total thyroidectomy for other indications. However, no study has directly compared these two groups of patients. The aim of this study was to determine whether there was an increased incidence or severity of postoperative hypocalcemia in patients who underwent thyroidectomy for Graves' disease. An institutional review board-approved database was created of all patients who underwent thyroidectomy from 1998 to 2009 at the Johns Hopkins Hospital. There were a total of 68 patients with Graves' disease who underwent surgery. Fifty-five patients who underwent total thyroidectomy were randomly selected and served as control subjects. An analysis was conducted that examined potential covariates for postoperative hypocalcemia, including age, gender, ethnicity, preoperative alkaline phosphatase level, size of goiter, whether parathyroid tissue or glands were present in the specimen, and the reason the patient underwent surgery. Specific outcomes examined were calcium levels on postoperative day 1, whether or not patients experienced symptoms of hypocalcemia, whether or not Rocaltrol was required, the number of calcium tablets prescribed upon discharge, whether or not postoperative tetany occurred, and calcium levels 1 month after discharge. Each outcome was analyzed using a logistic regression. Graves' disease patients had a significantly (p-value < 0.001) higher odds of greater number of calcium tablets prescribed upon discharge. Further, 6 of 68 patients with Graves' disease and no patient in the control group were readmitted with tetany (p = 0.033). There was a trend, though not significant, toward patients with Graves' disease having a higher prevalence of hypocalcemia the day after thyroidectomy and 1 month later. Patients with Graves' disease are more likely to require increased dosages of calcium as well as experience tetany postoperatively than patients undergoing total thyroidectomy for other indications. This suggests that patients operated upon for Graves' disease warrant close followup as both inpatients and outpatients for signs and symptoms of hypocalcemia.

Mitral valve repair for myxomatous Barlow disease is a challenging procedure requiring complex surgery with less than optimal results. The use of ring-only repair has been previously reported but never analyzed or followed-up. We investigated this simple valve repair approach for patients with Barlow disease and multisegment involvement causing mainly central jet. Of 572 patients who underwent mitral valve repair for mitral regurgitation at our medical center, 24 with Barlow disease (aged 47 ± 14 years; 46% male) underwent ring-only repair. Patients were characterized by severely enlarged mitral valve annulus, multisegment prolapse involving both leaflets, and demonstrated mainly a central wide regurgitant jet. Surgical technique included only the implantation of a large mitral annuloplasty ring. Early and late outcome results were compared with those of the remaining patients who underwent conventional mitral valve repair for degenerative disease (controls). All ring-only patients presented with moderate-severe/severe mitral regurgitation (vena contracta, 0.6 ± 0.1 cm; regurgitation volume, 52 ± 17 mL), with mainly a central jet and almost preserved ejection fraction (59% ± 6%). Cardiopulmonary bypass and crossclamp times were significantly shorter compared with controls (P < .0001). At follow-up (ring-only, 38 ± 36 months and controls, 36 ± 29 months), there were no late deaths in the ring-only group compared with 19 (4%) in the controls. Late follow-up revealed New York Heart Association functional class I or II in 95% of ring-only patients, compared with 90% of controls. Freedom from recurrent moderate or severe mitral regurgitation was 100% and 89% in the ring-only and control groups, respectively. Mitral annuloplasty for Barlow disease patients with multisegment involvement and mainly central regurgitant jet is both simple and reproducible with excellent late outcomes.

To retrospectively compare the pain control requirements of patients undergoing computed tomography (CT)-guided percutaneous radiofrequency (RF) ablation with those of patients undergoing CT-guided percutaneous cryoablation of small (< or = 4-cm) renal tumors. The study was HIPAA compliant and received institutional review board exemption; informed consent was not required. Medical and procedure records of patients who underwent RF ablation and cryoablation of renal tumors from June 19, 2003, to February 28, 2004, were retrospectively reviewed for clinical data, tumor characteristics, and anesthesia information. During the study period, 10 men (mean age, 66.5 years) underwent cryoablation of 11 renal lesions, and 14 patients (11 men, four women; mean age, 68.1 years) underwent RF ablation of 15 renal tumors. Analgesic and sedative requirements during the procedure were compared. Standard anesthesia consisted of 5 mL of 1% lidocaine injected locally, and conscious sedation consisted of 50 microg of fentanyl and 1 mg of midazolam administered intravenously. The Fisher exact test and Student t test were used to compare clinical factors and drug requirements between the two groups. There was no difference in terms of patient demographics, tumor diameter, or distribution of central versus noncentral lesions between the two groups. Cryoablation was associated with a significantly lower dose of fentanyl (165.0 microg [RF group] vs 75.0 microg [cryoablation group]; P < .001) and midazolam (2.9 mg [RF group] vs 1.6 mg [cryoablation group]; P = .026). In the RF group, one patient required general anesthesia, one patient required supplemental narcotics (5 mg of oxycodone) and sedatives (1 mg lorezapam), and one patient became apneic for a brief interval after receiving additional narcotics for pain during the procedure. An additional RF session was terminated early in one patient because of pain, and further medication could not be administered owing to bradycardia. No patients in the cryoablation group required any additional or alternate anesthetics. Image-guided percutaneous cryoablation of small (< or = 4-cm) renal lesions appears to require less analgesia than RF ablation. Prospective trials with validated pain scales are needed to examine this further. RSNA, 2005

Background Radiofrequency ablation (RFA) and microwave ablation (MWA) are the most frequently used thermal ablation methods for the treatment of liver cancer. Liver abscess is a common and severe complication of thermal ablation treatment. Objectives The objective of this study was to determine the incidence and risk factors of liver abscess formation after thermal ablation of liver cancer. Materials and Methods The clinical data of 423 patients who underwent 691 thermal ablation procedures for liver cancer were collected in order to retrospectively analyze the basic characteristics, incidence, and risk factors associated with liver abscess formation. Patients with multiple risk factors for liver abscess formation were enrolled in a risk factor group, and patients with no risk factors were enrolled in a control group. The chi-square test and multiple logistic regression analysis were used to analyze the relationship between the occurrence of liver abscesses and potential risk factors. Results Two hundred and eight patients underwent 385 RFA procedures, and 185 patients underwent 306 MWA procedures. The total incidence of liver abscesses was 1.7%, while the rates in the RFA group (1.8%) and MWA groups (1.6%) were similar (P > 0.05). The rates of liver abscesses in patients who had child-pugh class B and class C cirrhosis (P = 0.0486), biliary tract disease (P = 0.0305), diabetes mellitus (P = 0.0344), and porta hepatis tumors (P = 0.0123) were 4.0%, 6.7%, 6.5%, and 13.0%, respectively. There was a statistically significant difference between these four groups and the control group (all P < 0.05). The incidence of liver abscesses in the combined ablation and percutaneous ethanol injection (PEI) group (P = 0.0026) was significantly lower than that of the ablation group (P < 0.05). Conclusions The incidence of liver abscesses after liver cancer thermal ablation is low. Child-Pugh Class B and Class C cirrhosis, biliary tract disease, diabetes mellitus, and porta hepatis tumors are four significant risk factors. Combined ablation and PEI reduces the rate of liver abscesses. PMID:27642345

To investigate the clinical role of Vitamin D in prognosis of Otitis media with effusion. This prospective-controlled study was conducted at otolaryngology department in Duzce University, Turkey. The study group comprised children who were diagnosed with Otitis media with effusion between September 2016 and February 2017. Control group was conducted with children underwent circumcision or inguinal hernia repair operations that confirmed with ENT examination they do not have any sign of otitis media. After 3 months of follow-up without any treatment, unresolved cases who were accepted as chronic otitis media with effusion were operated under general anesthesia for ventilation tube application. Study and control groups were assessed depending on the serum 25(OH)Vitamin D levels at the end of 3 months; < 15 ng/mL was accepted as vitamin D deficiency. The results were compared with the control group in terms of vitamin D levels. Also, subgroup analysis was performed addressing to the complete recovery otitis media with effusion and chronic otitis media with effusion. One-hundred-seventy-four children with otitis media with effusion and 80 control patients were included to the study. One-hundred-eight (62%) out of 174 patients with otitis media with effusion was completely recovered after a 3-months follow up. Of those 66 out of 174 children, they had persistent diseases, underwent ventilation tube insertion after a 3-months follow-up. The mean 25(OH)Vitamin D level was 18.98 ± 10.60 in otitis media with effusion group and 28.07 ± 14.10 in control group and the difference was statistically significant between the study and control group (p < 0.001). Vitamin D deficiency was observed in 33 out of 66 patients (50.0%) in chronic otitis media with effusion group whilst 35 out of 108 patients (32.4%) in complete recovery otitis media with effusion group (p = 0.021). The rate of 25(OH)Vitamin D deficiency was 25% in control group which was statistically different from chronic otitis media with effusion and recovery chronic otitis media with effusion groups (p = 0.006). This study not only shows the relationship between Vitamin D and otitis media with effusion development, but also demonstrates the effects of Vitamin D on otitis media with effusion prognosis. There is a significant association between 25(OH)Vitamin D deficiency and follow-up outcomes of otitis media with effusion. Copyright © 2017 Elsevier B.V. All rights reserved.

To evaluate the efficacy and safety of peripheral vitrectomy under air infusion in comparison with fluid infusion in patients undergoing 23-gauge pars plana vitrectomy for primary rhegmatogenous retinal detachment. A total of 80 eyes of 80 patients with primary rhegmatogenous retinal detachment were enrolled into the study. Forty cases underwent peripheral vitrectomy under air infusion (air group), and a control group of equal number underwent peripheral vitrectomy under fluid infusion (fluid group). Peripheral iatrogenic retinal breaks during peripheral vitrectomy, postoperative visual acuities, and retinal redetachment rates were compared. The number of eyes with peripheral iatrogenic retinal breaks in air group during peripheral vitrectomy was statistically comparable with that in fluid group (1/40 and 4/40, 2.5% and 10%, respectively; P = 0.16). Scleral depression was necessitated in 7 of 40 cases (17.5%) during the operation in the air group. There were no statistically significant differences between the groups in means of postoperative visual acuity and retinal redetachment (P = 0.18 and P = 1.0, respectively). Peripheral vitrectomy under air infusion for primary rhegmatogenous retinal detachment revealed comparable results with fluid infusion in terms of intraoperative and postoperative complications and surgical outcomes.

In this research, the effectiveness of neurofeedback, along with virtual reality (VR), in reducing the level of inattention and impulsiveness was investigated. Twenty-eight male participants, aged 14-18, with social problems, took part in this study. They were separated into three groups: a control group, a VR group, and a non-VR group. The VR and non-VR groups underwent eight sessions of neurofeedback training over 2 weeks, while the control group just waited during the same period. The VR group used a head-mounted display (HMD) and a head tracker, which let them look around the virtual world. Conversely, the non-VR group used only a computer monitor with a fixed viewpoint. All participants performed a continuous performance task (CPT) before and after the complete training session. The results showed that both the VR and non-VR groups achieved better scores in the CPT after the training session, while the control group showed no significant difference. Compared with the other groups, the VR group presented a tendency to get better results, suggesting that immersive VR is applicable to neurofeedback for the rehabilitation of inattention and impulsiveness.

This is a single blind randomized controlled trial to examine the effect of virtual reality-based training on the community ambulation in individuals with stroke. Twenty subjects with stroke were assigned randomly to either the control group (n=9) or the experimental group (n=11). Subjects in the control group received the treadmill training. Subjects in the experimental group underwent the virtual reality-based treadmill training. Walking speed, community walking time, walking ability questionnaire (WAQ), and activities-specific balance confidence (ABC) scale were evaluated. Subjects in the experimental group improved significantly in walking speed, community walking time, and WAQ score at posttraining and 1-month follow-up periods. Their ABC score also significantly increased at posttraining but did not maintain at follow-up period. Regarding the between-group comparisons, the experimental group improved significantly more than control group in walking speed (P=0.03) and community walking time (P=0.04) at posttraining period and in WAQ score (P=0.03) at follow-up period. Our results support the perceived benefits of gait training programs that incorporate virtual reality to augment the community ambulation of individuals with stroke.

To compare the performance of absorbable gelatin sponge (AGS) with polyurethane foam (PUF) as middle ear packing material after mucosal trauma. Using a randomized, controlled and blinded study design fifteen guinea pigs underwent middle ear surgery with mucosal trauma performed on both ears. One ear was packed with either PUF or AGS while the contralateral ear remained untreated and used as non-packed paired controls. Auditory brainstem response (ABR) thresholds were measured pre-operatively and repeated at 1, 2, and 6weeks postoperatively. Histological analysis of middle ear mucosa was done in each group to evaluate the inflammatory reaction and wound healing. Another eighteen animals underwent middle ear wounding and packing in one ear while the contralateral ear was left undisturbed as control. Twelve guinea pigs were euthanized at 2weeks postoperatively, and six were euthanized at 3days post-operatively. Mucosal samples were collected for analysis of TGF-β1 levels by enzyme-linked immunosorbent assay. ABR recordings demonstrate that threshold level changes from baseline were minor in PUF packed and control ears. Threshold levels were higher in the AGS packed ears compared with both control and PUF packed ears for low frequency stimuli. Histological analysis showed persistence of packing material at 6weeks postoperatively, inflammation, granulation tissue formation, foreign body reaction and neo-osteogenesis in both AGS and PUF groups. TGF-β1 protein levels did not differ between groups. PUF and AGS packing cause inflammation and neo-osteogenesis in the middle ear following wounding of the mucosa and packing.

Spiritual elements play an important role in the recovery process from acute postoperative pain. This study was conducted to assess the effect of pray meditation on postoperative pain reduction and physiologic responds among muslim patients who underwent cesarean surgery under spinal anesthesia. This double-blinded randomized clinical trial study was conducted among muslim patients who underwent cesarean surgery under spinal anesthesia during 2011-2013 at tertiary regional and teaching hospital in Lorestan, Iran. The patients were randomly divided into interventional group (n=80) and control group (n=80). For about 20 minutes using a disposable phone mentioned and listened to pray meditation "Ya man esmoho davaa va zekroho shafa, Allahomma salle ala mohammad va ale mohammad" in interventional group and phone off in control group. Before and during pray meditation, 30, 60 minutes, 3 and 6 hours after pray meditation pain intensity, blood pressure, heart rate and respiratory rate were measured. No statistically significant improvement in pain score was found before and during pray meditation, 30, 60 minutes after pray meditation (P>0.05). Statistically significant improvement in pain score was found at 3 and 6 hours after pray meditation than control group (1.5 ± 0.3 vs. 3 ± 1.3, P=0.030) and (1.3 ± 0.8 vs. 3 ± 1.1, P=0.003). However, there was no significant difference in the physiological responses (systolic and diastolic blood pressure, respiration, and heart rate) any time between the groups. Religion and spirituality intervention such as pray meditation could be used as one of non-pharmacological pain management techniques for reducing pain after cesarean surgery. Also, Pray meditation provides less postoperative nausea and vomiting (PONV) and more relaxation.

Purpose: Children from multicultural families face physical, social, mental, and intellectual hurdles; however, relative interventions are lacking in South Korea (hereafter Korea) in this regard. The purpose of this study was to investigate the effects of regular Taekwondo (TKD) training on physical fitness, mood, sociability, and cognitive functions in these children. Methods: This study included 30 children from multicultural families in Korea who were randomly assigned to a TKD group (n = 15) and control group (n = 15). The children in TKD group underwent 16 weeks of TKD training once a week for 60 min. Each participant underwent a basic fitness test and sociability questionnaire before and after the intervention. Furthermore, we examined the changes in the mood and cognitive function by determining the profile of mood states (POMS), and Stroop color and word test, respectively. Results: Results of the Stork test of balance were significantly higher in the TKD group after intervention (p < 0.05). In terms of sub-variables, POMS, tension, and depression scores were significantly lower (p < 0.05) after the intervention, while the vigor score was significantly higher in the intervention group than those in the control group (p < 0.05). Furthermore, sociability and ‘being left out’ score, a sub-variable of sociability, was significantly lower (p < 0.05) after the intervention, while sociability score was significantly higher (p < 0.05). Conclusions: Our findings suggest that participation in regular TKD training can be effective for balanced improvements in variables of basic fitness and that it exerts a positive effect on the mood and development of sociability.

OBJECTIVE: To determine the outcome of vestibular rehabilitation protocols in subjects with peripheral vestibular disorders compared with normal and abnormal control subjects. STUDY DESIGN: Prospective study using repeated measure, matched control design. Subjects were solicited consecutively according to these criteria: vestibular disorder subjects who had abnormal results of computerized dynamic posturography (CDP) sensory organization tests (SOTs) 5 and 6 and underwent rehabilitation; vestibular disorder subjects who had abnormal results of SOTs 5 and 6 and did not undergo rehabilitation; and normal subjects (normal SOTs). SETTING: Tertiary neurotology clinic. SUBJECTS: Men and women over age 18 with chronic vestibular disorders and chief complaints of unsteadiness, imbalance, and/or motion intolerance, and normal subjects. INTERVENTIONS: Pre- and post-rehabilitation assessment included CDP, vestibular disability, and activities of daily living questionnaires. Individualized rehabilitation plans were designed and implemented to address the subject's specific complaints and functional deficits. Supervised sessions were held at weekly intervals, and self-administered programs were devised for daily home use. MAIN OUTCOME MEASURES: CDP composite and SOT scores, number of falls on CDP, and self-assessment questionnaire results. RESULTS: Subjects who underwent rehabilitation (Group A) showed statistically significant improvements in SOTs, overall composite score, and reduction in falls compared with abnormal (Group B) control groups. Group A's performances after rehabilitation were not significantly different from those of normal subjects (Group C) in SOTs 3 through 6, and close to normal on SOTs 1 and 2. Subjects in Group A also reported statistically significant symptomatic improvement. CONCLUSIONS: Outcome measures of vestibular protocol physical therapy confirmed objective and subjective improvement in subjects with chronic peripheral vestibular disorders. These findings support results reported by other investigators.

Background: The association between epicardial fat thickness (EFT) and premature coronary artery disease (CAD) has not been elaborately studied. Objectives: In the present study, we sought whether such a relationship between EFT and CAD exists. Patients and Methods: Sixty two consecutive subjects, under 50 years of age, who underwent coronary angiography (CAG) with the aspect of CAD, were included in this case control study. They were divided into two groups of 31 subjects, namely CAD (cases) and non-CAD (controls) group, according to CAG data. Presence of conventional coronary risk factors, drug history, and anthropometric data were recorded. Then, each subject underwent standard transthoracic echocardiography for measuring EFT in the proximal part of right ventricular outflow tract in the parasternal long axis view at end diastole, as well as other parameters of systolic and diastolic function, and left ventricle (LV) mass. Images were stored for offline analysis when the echocardiocardiographers were blind to CAG data. Results: Among baseline characteristics, waist circumference, triglyceride levels, cigarette smoking and history of statin use were significantly higher in the CAD group. The body mass index (BMI) was significantly higher in the non-CAD group. According to echocardiographic data, the EFT with a cut off value of 2.95 mm could well differentiate subjects in each group. The LV mass and E/e were significantly higher in CAD group, in addition to EFT. Also, there was a significant correlation between EFT and waist circumference, as well as LV mass. However, no significant relation was between EFT and LV systolic and diastolic function. Conclusions: The EFT, as measured by echocardiography, with a cut off value 2.95 mm has a strong association with premature CAD. PMID:26380819

To study postoperative pain relief in major gynaecological surgery by perioperative parecoxib administration in Thammasat University Hospital. This double-blind randomized controlled clinical trial was conducted in Thammasat University Hospital, Pathumthani, Thailand from October 2013 to May 2014. One hundred and twenty patients who underwent elective gynaecological surgery were randomized assigned to study and control groups. Study group (n = 60) received 40 mg parecoxib and control group (n = 60) received placebo at 1 hour before surgery. The postoperative visual analog scale (VAS) at 3, 6, 12 and 24 hours, frequency of meperidine consumption in 24 hours and side effects of parecoxib were recorded. VAS of study group after operation at 3, 6, 12 and 24 hours was significantly lower than control group. Meperidine consumption in placebo group was significantly higher than study group (27.50 ± 19.36 and 48.75 ± 28.15 mg, respectively; p < 0.001). There was no side effect from parecoxib in this study. Intravenous postoperativeparecoxib injection could relief pain and reduced meperidine consumption. Parecoxib could be safely used in gynaecological surgery for postoperative pain relief

Veno-occlusive disease (VOD) of the liver occurs in 10% to 50% of patients after allogeneic stem cell transplantation, ranging from mild reversible disease to severe disease, with a mortality rate almost always close to 100%. Recently, promising results in the treatment of established VOD with defibrotide were reported. Therefore, defibrotide may be used as a prophylactic regimen for hepatic VOD in stem cell transplantation for hematologic malignancies. Fifty-two successive patients who underwent transplantation between October 1999 and June 2002 received defibrotide prophylaxis intravenously from day -7 to day +20 after transplantation in addition to heparin and were compared with historical controls who underwent transplantation successively between February 1997 and September 1999. In the defibrotide group, the maximum total bilirubin levels and the number of patients with serum levels exceeding 50 micromol/L were significantly lower than in the control group (5 of 52 versus 18 of 52, respectively; P =.004). None of the 52 patients developed VOD (Baltimore criteria), and no side effects occurred. These results were significantly different (P =.001) from controls (10/52 [19%] with VOD, 3 of whom died of severe VOD). In addition, day 100 event-free survival was significantly higher in the study group (P =.02), with a trend toward better day 100 overall survival (P =.07). These results suggest that defibrotide given in addition to heparin may be an efficient prophylaxis for VOD.

In this paper, the authors investigate the effects of anterior cervical decompression (ACD) on swallowing and vocal function. The study comprised 114 patients who underwent ACD. The early group (50 patients) was examined immediately pre- and postoperatively, and the late group (64 patients) was examined at only 3 to 9 months postoperatively. Fifty age- and sex-matched patients from the Department of Otorhinolaryngology-Head and Neck Surgery who had not been intubated in the previous 5 years were used as a control group. All patients in the early and control groups were examined by a laryngologist; patients in the late group were examined by a laryngologist and a neurosurgeon. Videolaryngostroboscopy was performed in all members of the patient and control groups, and the function of the ninth through 12th cranial nerves were clinically evaluated. Data were collected concerning swallowing, voice quality, surgery results, and health-related quality of life. Patients with persistent dysphonia were referred for phoniatric evaluation and laryngeal electromyography (EMG). Those with persistent dysphagia underwent transoral endoscopic evaluation of swallowing function and videofluorography. Sixty percent of patients in the early group reported dysphonia and 69% reported dysphagia at the immediate postoperative visit. Unilateral vocal fold paresis occurred in 12%. The prevalence of both dysphonia and dysphagia decreased in both groups 3 to 9 months postoperatively. All six patients with vocal fold paresis in the early group recovered, and in the late group there were two cases of vocal fold paresis. The results of laryngeal EMG were abnormal in 14 of 16 patients with persistent dysphonia. Neither intraoperative factors nor age or sex had any effect on the occurrence of dysphonia, dysphagia, or vocal fold paresis. Most patients were satisfied with the surgical outcome. Dysphonia, dysphagia, and vocal fold paresis are common but usually transient complications of ACD. Recurrent laryngeal nerve damage detected by EMG is not rare. Pre-and postoperative laryngeal examination of ACD patients should be considered.

This study aimed to investigate the effect of endometrial injury using Pipelle catheter in the follicular phase (cycle day 5, 6, or 7) of the stimulation cycle on pregnancy rates in patients undergoing intrauterine insemination. This prospective randomized controlled study was carried out in the Assisted Reproductive Technology Unit of Ain Shams University Maternity Hospital, Cairo, Egypt, from July 1, 2013 to August 31, 2015. Three hundred sixty women, 20 to 35 years of age, with patent fallopian tubes, mild male factor infertility, or unexplained infertility were recruited. Participants were allocated randomly into 2 groups: experimental arm and control arm. Women in the experimental arm underwent endometrial biopsy using a Pipelle catheter on day 5, 6, or 7 of the stimulation cycle combined with intrauterine insemination. Women in the control group underwent intrauterine insemination with no endometrial biopsy done. The primary outcomes were the clinical and chemical pregnancy rates. Data of 344 participants were statistically analyzed. The chemical pregnancy rate was 23.66% in the experimental arm and 10.85% in the control arm (P = .002). The clinical pregnancy rate was 18.93% in the experimental arm and 7.42% in the control arm (P = .003). Endometrial injury using a Pipelle catheter in the stimulation cycle may improve pregnancy rates in women undergoing intrauterine insemination. © The Author(s) 2016.

Objective: To determine reproductive outcome after in-vitro fertilization/embryo transfer (IVF-ET) in women with primary infertility following hysteroscopic septoplasty of incomplete uterine septum or arcuate uterine anomaly. Methods: This is a historical cohort study. The study group consisted of 156 consecutive patients who underwent a total of 221 cycles of IVF/ET following hysteroscopic septoplasty of an incomplete uterine septum or arcuate anomaly (Group 1). The control group included 196 consecutive patients with normal endometrial cavity on hysteroscopy who underwent a total of 369 cycles of IVF/ET (Group 2). The reproductive outcome after the first cycle of IVF-ET and the best reproductive outcome of all the cycles the patient underwent were calculated. In addition, we compared the reproductive outcome in the study group based on the type of the anomalies (septum versus arcuate). Results: In the first fresh cycle, following septoplasty, there were significantly higher clinical pregnancy and delivery rates in Group 1 (60.3% and 51.3% respectively) compared to Group 2 (38.8% and 33.2% respectively). However, there was no significant difference between the two groups in the clinical pregnancy (74.4% vs. 67.3%) or in the delivery (65.4% vs. 60.2%) rates per patient, respectively. There was no significant difference in the reproductive outcome after IVF-ET between patients who previously had arcuate uterine anomaly versus incomplete uterine septum. Conclusion: Reproductive outcome of IVF-ET after hysteroscopic correction of incomplete uterine septum/arcuate uterine anomaly in women with primary infertility is no different from women with normal uterine cavity.

Pituitary surgery has seen a recent shift from a microscopic to an endoscopic trans-sphenoidal approach. We present our early experience with endoscopic surgery and compare the outcome with our recent microscopic experience. From January 2008 until present time, 80 consecutive patients underwent trans-sphenoidal pituitary surgery in our institution. Until September 2009, all patients had a microscopic trans-septal approach. After this time, the patients underwent endoscopic trans-sphenoidal surgery. All patients underwent pre- and post-operative MRI and full endocrinological evaluation. Data was collected prospectively including tumour volume, endocrine function, visual function, length of stay and complications. There were 40 patients in each group. In the microscopic group, there were 26 non-functioning tumours and 14 functioning tumours. In the endoscopic group, there were 24 non-functioning and 16 functioning tumours. There were significantly better results in terms of tumour resection (p = 0.002) and remission (p = 0.018) in the endoscopic group. In this group there was also a lower incidence of CSF leaks and a shorter length of stay for secreting tumours (p = 0.005). 1 patient in the endoscopic group died at day 43 post-operatively, having initially presented in a poor clinical state with pituitary apoplexy. Microscopic trans-sphenoidal surgery remains the benchmark for future surgical techniques. Our early results suggest that endoscopic trans-sphenoidal surgery provides favourable results in both tumour resection and control of secreting tumours in comparison with microscopic surgery. Further longer-term evaluation is required to ensure the outcome of endoscopic surgery.

The authors assess the long-term safety and efficacy of cervical disc replacement with the Prestige Cervical Disc in a prospective, randomized, multicenter trial at 7 years of follow-up. At 31 investigational sites, 541 patients with single-level cervical disc disease with radiculopathy were randomized to 1 of 2 treatment groups: 276 investigational group patients underwent anterior cervical discectomy and arthroplasty with the Prestige disc, and 265 control group patients underwent anterior cervical discectomy and fusion. Clinical outcomes included Neck Disability Index, the 36-Item Short-Form Health Survey, and neck and arm pain scores. Radiographs were assessed for angle of motion and fusion. Clinical and radiographic outcomes were evaluated preoperatively, intraoperatively, and at 1.5, 3, 6, 12, 24, 36, 60, and 84 months. Of the 541 patients treated, 395 patients (73%; 212 investigational and 183 control patients) completed 7 years of clinical follow-up. Significant improvements achieved by 1.5 months in both groups were sustained at 7 years. In the investigational group, mean Neck Disability Index improvements from preoperative scores were 38.2 and 37.5 at 60 and 84 months, respectively. In the control group, the corresponding means were 33.8 and 31.9. The differences between the investigational and control groups at the 60-month and 84-month periods were significant (p = 0.014 and 0.002, respectively). The overall rates of maintenance or improvement in neurological status in the investigational group were significantly higher: 92.2% and 88.2% at 60 months and 84 months, respectively, compared with 85.7% and 79.7% in the control group (p = 0.017 and 0.011, respectively). At 84 months, the percentage of working patients in the investigational group was 73.9%, and in the control group, 73.1%. Postoperatively, the implant effectively maintained average angular motion of 6.67° at 60 months and 6.75° at 84 months. Cumulative rates for surgery at the index level were lower (p < 0.001) in the investigational group (11 [4.8%] of 276) when compared with the control group (29 [13.7%] of 265) (based on life-table method), and there were statistical differences between the investigational and control groups with specific regard to the rate of subsequent revision and supplemental fixation surgical procedures. Rates for additional surgical procedures that involved adjacent levels were lower in the investigational group than in the control group (11 [4.6%] of 276 vs. 24 [11.9%] of 265, respectively). Cervical disc arthroplasty has the potential for preserving motion at the operated level while providing biomechanical stability and global neck mobility and may result in a reduction in adjacent-segment degeneration. The Prestige Cervical Disc maintains improved clinical outcomes and segmental motion after implantation at 7-year follow-up. Clinical trial registration no. NCT00642876 ( ClinicalTrials.gov ).

Objective To study the effect of oral administration of a nitric oxide (NO) donor l-arginine (l-Arg), a NO synthase inhibitor NG-nitro-l-arginine methyl ester (l-NAME) and an inhibitor of xanthine oxidase, allopurinol (Allo), on serum NO concentration and catalase activity after intestinal ischemia/reperfusion (I/R) in rats. Methods Male Wistar rats received per os l-Arg (800 mg/kg) or l-NAME (50 mg/kg) or Allo (100 mg/kg) 24 hrs, 12 hrs and 1 hr before underwent 1 hr occlusion of superior mesenteric artery followed by 1 hr of reperfusion (l-Arg(IR1), l-NAME(IR1) and Allo(IR1) respectively) or 1 hr occlusion followed by 8 hrs of reperfusion (l-Arg(IR8), l-NAME(IR8) and Allo(IR8) respectively). There was one group underwent 1 hr occlusion (I), a group underwent 1 hr occlusion followed by 1 hr reperfusion (IR1), a group subjected to 1 hr occlusion followed by 8 hrs of reperfusion (IR8) and a last group that served as control (C). Serum NO concentration and catalase activity were measured. Results After 1 hr of reperfusion serum NO concentration was elevated in IR1 and l-Arg(IR1) groups compared with group C but not in l-NAME(IR1) and Allo(IR1) group. Catalase activity was enhanced in l-NAME(IR1) group. Interestingly, serum NO concentration was increased after 8 hrs of reperfusion in all groups (IR8, l-Arg(IR8), l-NAME(IR8) and Allo(IR8)) compared with control while catalase activity did not show significant difference in any group. Conclusions The results of the present study show that NO concentration is elevated in serum after intestinal I/R and the elevation sustained after administration of l-Arg but not after administration of l-NAME or Allo after 1 hr reperfusion. However, after 8 hrs of reperfusion NO concentration was increased in all groups studied, focusing attention on its possible important role in a complicated situation such as intestinal I/R that involves intestine and other organs. Serum catalase activity does not seem to be affected by per os supplementation of l-Arg or Allo in intestinal I/R. PMID:18561519

To identify the effects of a smart program for the patients who underwent percutaneous coronary intervention (SP-PCI) on coronary disease-related knowledge, health behaviors, and quality of life. A nonequivalent control group with a non-synchronized design was utilized and 48 participants (experimental=22, control=26) were recruited from a university hospital in Gyeongsang area from May to December, 2016. The 12-week SP-PCI consisted of self-study of health information using smart phone applications (1/week), walking exercise (>5/week) using smart band, feedback using Kakao talk (2/week), and telephone counseling (1/week). Patients in the control group received usual care from their primary health care providers and a brief health education with basic self-management brochure after the PCI. Data were analyzed using the SPSS 21.0 program through descriptive statistics, χ² test, and t-test. After the 12-week SP-PCI, the experimental group showed higher levels of coronary disease-related knowledge (t=2.43, p=.019), heart-related health behaviors (t=5.96, p<.001), regular exercise (Z=-4.47, p<.001), and quality of life-MCS (t=3.04, p=.004) and showed lower levels of stress (Z=-3.53, p<.001) and sodium intake (t=-4.43, p<.001) than those in the control group. There were no significant group differences in medication adherence and food intake in total energy, lipids, and cholesterol. The suggested SP-PCI provided easy access and cost-effective intervention for patients after PCI and improved their knowledge of the disease, performance of health behaviors, and quality of life. Further study with a wider population is needed to evaluate the effects of SP-PCI on disease recurrence and quality of life for patients after PCI. © 2017 Korean Society of Nursing Science

Podcasting has recently emerged as an important information technology tool for health professionals. Podcasts can be viewed online or downloaded to a user computer or a handheld multimedia device like a portable MP3 player, smart phone and tablet device. The principal advantage of the podcast is that the presentation of information need not be linked with any particular time or location. Since students are familiar with newer technology tools and may be using it on a regular basis, video podcast could serve as a convenient tool for students to help remember both conceptual and factual information. The purpose of this study was to assess the attitude of first year dental students towards video podcast supplementation and to assess the efficacy of video podcast as a teaching aid in comparison to text book reading. First year dental students were recruited for this study. A didactic lecture class was conducted for the students (n=100). The students were then randomly divided into two groups. Students present in group A (n=46) underwent a video podcast session followed by a multiple choice question test. This was followed by student feedback to assess the usefulness of video podcast. Students belonging to group B (n=54) had a study session for 20 minutes followed by the MCQ test. Students then underwent the video podcast session followed by feedback to assess the utility of video podcast. Mann-Whitney U test was applied to compare the difference in the median MCQ score between the two groups. The findings revealed a significant gain in the median MCQ score in the intervention group (group A) when compared to control group (Group B). In the feedback form, 89% of students agreed that the video podcast might be useful as it would enable them to view slides and hear the lectures repeatedly. Students who underwent the video podcast session performed significantly better in the MCQ test compared to students who underwent text book reading alone. This demonstrates an advantage of video podcasts over text book reading. Majority of students accepted the benefits of video podcast supplementation.

Heart failure (HF) and atrial fibrillation (AF) are associated with sympathetic activation. Renal sympathetic denervation (RSD) can suppress AF vulnerability. The impact of RSD on atrial electrophysiology in experimental HF is unclear. Twenty-two beagles were randomized into control, HF, and HF + RSD groups. Control dogs were implanted cardiac pacemakers without pacing. Dogs in the HF group underwent right ventricular pacing for 3 weeks at 240 beats/min to induce HF. The dogs in the HF + RSD group received RSD and underwent the same HF-inducing procedure. The P-wave dispersion was higher in HF dogs than in the control and HF + RSD dogs (19 ± 3.1 ms vs 13 ± 2.3 ms, 15 ± 2.9 ms, P = 0.04). Conduction time within the interatrium was significantly longer in the HF dogs than that in the control and HF + RSD dogs (39 ± 4 ms vs 31 ± 3 ms, 33 ± 4 ms; P = 0.03). Window of vulnerability (WOV) of AF was widened in the HF dogs than in the HF + RSD dogs (37 ± 5 ms vs 14 ± 3 ms; P < 0.01), while AF could not be induced (WOV = 0) in the control dogs during S1 S2 stimulation. The voltage in the threshold for AF inducibility was lower during ganglionated plexi stimulation in the HF dogs than in the control and HF + RSD dogs (1.8 ± 0.6 V vs 2.5 ± 0.6 V, 2.4 ± 0.4 V; P = 0.04). RSD could reverse the atrial electrical remodeling and decrease AF inducibility in dogs with pacing-induced HF. ©2014 Wiley Periodicals, Inc.

Objective Docosahexaenoic acid (DHA) is a dietary fatty acid with neuroprotective properties. We hypothesized that DHA treatment after hypoxia-ischemia (HI) would improve function and reduce brain volume loss in a perinatal rat model. Study design Seven-day-old Wistar rat pups from 7 litters (N=84) underwent right carotid ligation, followed by 8% O2 for 90 minutes. Fifteen minutes after HI, pups were divided into 3 treatment groups (intraperitoneal injections of DHA 1, 2.5 or 5 mg/kg) and 2 control groups (25% albumin or saline). At 14 days, rats underwent vibrissae-stimulated forepaw placing testing, and bilateral regional volumes were calculated for cortex, striatum, hippocampus, and hemisphere. Results Post HI treatment with DHA significantly improved vibrissae forepaw placing (complete responses: 8.5±2 treatment vs. 7.4±2 controls; normal=10; p = 0.032, t-test). Post injury DHA treatment did not attenuate brain volume loss in any region. Conclusion Post-hypoxia-ischemia DHA treatment significantly improves functional outcome. PMID:20691409

This study was designed to observe the efficacy and safety of renal denervation from the inside and outside of renal arteries. Fourteen beagles were randomly divided into a control group (n = 4) and treatment group (n = 10). One renal artery in every beagle of the treatment group was randomly assigned to an intimal group (10 renal arteries) which underwent percutaneous renal denervation from the inside, and another renal artery was assigned to an adventitial group (10 renal arteries) which underwent renal denervation from the outside by laparotomy. Compared with the intimal group, the renal norepinephrine (NE) concentration in the adventitial group had significantly decreased (p = 0.003) at 3 months postsurgery. Renal artery HE staining showed that the perineurium from the adventitial group appeared thickened. Western blotting showed that renal tissue tyrosine hydroxylase (TH) protein expression in the adventitial group was significantly lower than that in the intimal group (p < 0.01) at 3 months postsurgery. There was a renal artery stenosis and a renal atrophy in the intimal group after 1 month of follow-up. The inhibitory effect on renal sympathetic nerve activity was more effective in the adventitial group than the intimal group, and renal denervation in the former group was safe. © 2015 S.

Aims: The aim of this study was to detect Mycobacterium tuberculosis (MTB) DNA with polymerase chain reaction (PCR) in aqueous or vitreous samples of patients suffering from choroiditis presumed to be infectious origin. Settings and Design: Hospital-based, retrospective case–control study. Subjects and Methods: In all, forty eyes of forty patients with choroiditis divided into two groups – Group A (serpiginous-like choroiditis, ampiginous choroiditis, multifocal choroiditis) and Group B (choroidal abscess, miliary tuberculosis (TB), choroidal tubercle) were analyzed retrospectively. In 27 controls (patients without uveitis undergoing phacoemulsification), anterior chamber aspirate was done and sample subjected to real-time PCR. Patients underwent nested PCR for MTB using IS6110 and MPB64 primers from aqueous (n = 39) or vitreous (n = 1). All patients underwent detailed ophthalmological examination by slit-lamp biomicroscopy, fundus examination by indirect ophthalmoscopy, and fundus photograph and fundus fluorescein angiography if required. Statistical Analysis: Positive results of PCR for MTB within the group and between two groups were statistically analyzed using Chi-square test. Results: There were 25 males and 15 females. Mean age at presentation was 34.66 years (range, 14–62). PCR positivity rates were 41.3% (n = 12/29) and 81.82% (n = 9/11) in Groups A and B, respectively. No controls had PCR-positive result. Comparison of PCR positivity rates showed statistically significant difference between Groups A and B (P = 0.028). Systemic TB was detected in 57.14% (n = 12/21) of all PCR-positive cases (Group A - 33.3%, n = 4/12; Group B - 88.9%, n = 8/9). Systemic antitubercular treatment (ATT) for 9 months and oral steroids were successful in resolution of choroiditis in all PCR-positive patients (n = 21) without disease recurrence. Conclusions: Eyes with choroiditis of suspected/presumed tubercular origin should be subjected to PCR for diagnosis of TB and subjected to ATT for prevention of recurrences. PMID:28112131

Traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) have previously been reported to be associated with increased risk of Alzheimer's disease (AD). We are using biomarkers to study Vietnam Veterans with/without mild cognitive impairment with a history of at least one TBI and/or ongoing PTSD to determine whether these contribute to the development of AD. Potential subjects identified by Veterans Administration records underwent an initial telephone screen. Consented subjects underwent clinical evaluation, lumbar puncture, structural MRI and amyloid PET scans. We observed worse cognitive functioning in PTSD and TBI + PTSD groups, worse global cognitive functioning in the PTSD group, lower superior parietal volume in the TBI + PTSD group, and lower amyloid positivity in the PTSD group, but not the TBI group compared to controls without TBI/PTSD. Medial temporal lobe atrophy was not increased in the PTSD and/or TBI groups. Preliminary results do not indicate that TBI or PTSD increase the risk for AD measured by amyloid PET. Additional recruitment, longitudinal follow-up, and tau PET scans will provide more information in the future.

Muscle activity contributes to the enhancement of facial aging deformity, blepharospasm, cerebral palsy spasticity, trismus, torticollis, and other conditions. Myotomy of the involved muscles in order to reduce the deformity has variable success rates due to muscle healing and regeneration of activity. The goal of this study was to investigate whether blocking striated muscle activity with Botulinum toxin (BtxA) during the healing time after myotomy alters the healing process and reduces long-term muscle activity. Eighteen Sprague Dawley rats where divided into 3 groups: group A (n = 7) underwent myotomy of their Latisimus Dorsi muscle; group B (n = 7) underwent myotomy and injection of BtxA into their severed muscle; group C (n = 4) injection of BtxA only. Muscle strength was tested periodically using a grip test. Starting at week 16 and until the termination of study at week 22, group B (Myotomy + BtxA) showed significant reduction in muscle power compared to the two control groups. Addition of BtxA injection into a muscle immediately after myotomy may interfere with muscle healing and contribute to a more successful long-term result.

ABSTRACT Objective: to evaluate the effect of physical therapy on the range of motion of the shoulders and perimetry of the upper limbs in women treated with radiotherapy for breast cancer. Methods: a total of 35 participants were randomized into two groups, with 18 in the control group (CG) and 17 in the study group (SG). Both of the groups underwent three evaluations to assess the range of motion of the shoulders and perimetry of the upper limbs, and the study group underwent supervised physical therapy for the upper limbs. Results: the CG had deficits in external rotation in evaluations 1, 2, and 3, whereas the SG had deficits in flexion, abduction, and external rotation in evaluation 1. The deficit in abduction was recovered in evaluation 2, whereas the deficits in all movements were recovered in evaluation 3. No significant differences in perimetry were observed between the groups. Conclusion: the applied supervised physical therapy was effective in recovering the deficit in abduction after radiotherapy, and the deficits in flexion and external rotation were recovered within two months after the end of radiotherapy. Registration number of the clinical trial: NCT02198118. PMID:27533265

To evaluate the effects of massage therapy on transcutaneous bilirubin of stable preterm infants. The controlled clinical trial was conducted in 2014 at Shahid Hasheminejhad Hospital, Iran, and comprised preterm neonatal children in the neonatal intensive care unit. The newborns were divided into two groups of massage and control via random allocation. The children in the control group received the routine therapy whereas those in the massage group underwent the same four days of routine plus 20 minutes of massage twice a day. The transcutaneous bilirubin and the number of excretions of the newborns were noted from the first to the fourth day of the intervention and results were compared between the two groups. There were 40 newborns in the study l 20(50%) each in the two groups. There was a significant difference in the number of times of defecation (p=0.002) and in the level of bilirubin (p=0.003) between the groups with those in the massage group having a higher number of defecations as well as a lower level of transcutaneous bilirubin. Through massage therapy the bilirubin level in preterm newborns can be controlled and a need for phototherapy can also be delayed.

To determine the prevalence of celiac disease in children and adolescents with migraine, the authors investigated serum levels of tissue transglutaminase antibody immunoglobulin A and total immunoglobulin A from 81 children with migraine and in a healthy control group of 176 children. Study participants who were positive for tissue transglutaminase immunoglobulin A antibodies underwent a duodenal biopsy. Two patients in the migraine group (2.5%) and 1 in the control group (0.57%) tested positive for serum tissue transglutaminase immunoglobulin A antibodies (P > .05). Duodenal biopsy did not confirm celiac disease in both groups, and these patients were considered "potential celiac" cases. In the present study, children with migraine did not exhibit a higher prevalence rate of celiac disease compared with healthy controls. Therefore, the screening test for celiac disease is not a necessary part of the management of migraine in children. © The Author(s) 2016.

This was a retrospective study that evaluated the surgical outcomes of laparoscopic surgery (LS) for rectal cancer, in comparison with a case control series of open surgery (OS), during an 8-year period. Between October 1998 and December 2006, 203 patients with rectal malignancies underwent colectomy; 146 of them had colectomy with the traditional technique (OS), while 57 underwent resection of rectal cancer laparoscopically (LS). The LS group was compared with 60 patients from the OS group (selected from the 146 OS group patients), matched by size, sex, age, anatomical location of the tumor, type, extent of resection, and pathological stage. Data were obtained from patients' medical records. Statistical analysis was performed with the t test and chi-square test. All data are expressed as mean +/- standard error of the mean (SEM). Mean age of the LS group was 63.7+/-12 years versus 69+/-12 years in the OS group. There were more men than women in both the laparoscopic (33 males, 24 females) and OS groups (35 men, 25 women). The mean follow-up period was 38 months and 78 months for LS and OS groups, respectively. The procedure included low anterior resection (43 in LS and 45 in OS), and 13 patients in both groups underwent abdominoperineal resection and 3 transanal resections (2 in OS and 1 in LS). Mean tumor size was 4.2+/-2.12cm in the LS versus 5.2+/-2.02cm in the OS group. Conversion to an open procedure occurred in 4 patients (6.7%), all in the first 20 cases. Postoperative complications developed in 28 patients (11.7%), 13 in the LS group and 15 in the OS group. Median operative time was longer, but median blood loss was significantly lower in the LS group. The length of hospital stay was significantly shorter for the LS group. Laparoscopic surgery is feasible and safe for patients with rectal cancer and provides benefits during the postoperative period without increased morbidity or mortality.

Cataract is a leading cause of vision impairment worldwide, and surgery is the only available treatment. The process that initiates lens opacification is dependent on the oxidative stress experienced by the lens components. A healthy overall dietary pattern, with the potential to reduce oxidative stress, has been suggested as a means to decrease the risk of developing cataract. We aimed to investigate the hypothesis that an intervention with a Mediterranean diet (MedDiet) rather than a low-fat diet could decrease the incidence of cataract surgery in elderly subjects. We included 5802 men and women (age range: 55-80 years) from the Prevención con Dieta Mediterránea study (multicenter, parallel-group, randomized controlled clinical trial) who had not undergone cataract surgery. They were randomly assigned to one of three intervention groups: (1) a MedDiet enriched with extra-virgin olive oil (EVOO) ( n = 1998); (2) a MedDiet enriched with nuts ( n = 1914), and a control group recommended to follow a low-fat diet ( n = 1890). The incidence of cataract surgery was recorded yearly during follow-up clinical evaluations. Primary analyses were performed on an intention-to-treat basis. Cox regression analyses were used to assess the relationship between the nutritional intervention and the incidence of cataract surgery. During a follow-up period of 7.0 years (mean follow-up period: 5.7 years; median: 5.9 years), 559 subjects underwent cataract surgery. Two hundred and six participants from the MedDiet + EVOO group, 174 from the MedDiet + Nuts group, and 179 from the control group underwent cataract surgery. We did not observe a reduction in the incidence of cataract surgery in the MedDiet groups compared to the control group. The multivariable adjusted hazard ratios were 1.03 (95% confidence interval [CI]: 0.84-1.26, p = 0.79) for the control group versus the MedDiet + EVOO group and 1.06 (95% CI: 0.86-1.31, p = 0.58) for the control group versus the MedDiet + Nuts group. To our knowledge, this is the first large randomized trial assessing the role of a MedDiet on the incidence of cataract surgery. Our results showed that the incidence of cataract surgery was similar in the MedDiet with EVOO, MedDiet with nuts, and low-fat diet groups. Further studies are necessary to investigate whether a MedDiet could have a preventive role in cataract surgery.

Methods used for evaluation of cardiac risk before noncardiac surgery vary widely. We evaluated the effect over time on practice and resource utilization of implementing the American College of Cardiology/American Heart Association Guidelines on Preoperative Risk Assessment. We compared 102 historical control patients who underwent elective abdominal aortic surgery (from January 1993 to December 1994) with 94 consecutive patients after guideline implementation (from July 1995 to December 1996) and 104 patients in a late after guideline implementation (from July 1, 1997, to September 30, 1998). Resource use (testing, revascularization, and costs) and outcomes (perioperative death and myocardial infarction) were examined. Patients with and without clinical markers of risk for perioperative cardiac complications were compared. The use of preoperative stress testing (88% to 47%; P <.00001), cardiac catheterization (24% to 11%; P <.05), and coronary revascularization (25% to 2%; P <.00001) decreased between control and postguideline groups, respectively. These changes persisted in the late postguideline group. Mean preoperative evaluation costs also fell ($1087 versus $171; P <.0001). Outcomes of death (4% versus 3% versus 2%) and myocardial infarction (7% versus 3% versus 5%) were not significantly different between control, postguideline, and late postguideline groups, respectively. Stress test rates were similar for patients at low risk versus high risk in the historical control group (84% versus 91%; P =.29) but lower for patients at low risk after guideline implementation (31% versus 61%; P =.003). Implementation of the American College of Cardiology/American Heart Association cardiac risk assessment guidelines appropriately reduced resource use and costs in patients who underwent elective aortic surgery without affecting outcomes. This effect was sustained 2 years after guideline implementation.

Objective: To evaluate the effect of the ischemic post-conditioning (IPC) on the prevention of the cardio-renal damage in patients with acute ST-segment elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PPCI). Methods: A total of 251 consecutive STEMI patients underwent PPCI in the heart center of Tianjin Third Central Hospital from January 2012 to June 2014 were enrolled in this prospective, randomized, control, single-blinded, clinical registry study. Patients were randomly divided into IPC group (123 cases) and control group (128 cases) with random number table. Patients in IPC group underwent three times of inflation/deflation with low inflation pressure using a balloon catheter within one minute after culprit vessel blood recovery, and then treated by PPCI. Patients in control group received PPCI procedure directly. The basic clinical characteristics, incidence of reperfusion arrhythmia during the procedure, the rate of electrocardiogram ST-segment decline, peak value of myocardial necrosis markers, incidence of contrast induced acute kidney injury(CI-AKI), and one-year major adverse cardiovascular events(MACE) which including myocardial infarction again, malignant arrhythmia, rehospitalization for heart failure, repeat revascularization, stroke, and death after the procedure were analyzed between the two groups. Results: The age of IPC group and control group were comparable((61.2±12.6) vs. (64.2±12.1) years old, P =0.768). The incidence of reperfusion arrhythmia during the procedure was significantly lower in the IPC group than in the control group(42.28% (52/123) vs. 57.03% (73/128), P =0.023). The rate of electrocardiogram ST-segment decline immediately after the procedure was significantly higher in the IPC group than in the control group (77.24% (95/123) vs. 64.84% (83/128), P =0.037). The peak value of myocardial necrosis markers after the procedure were significantly lower in the IPC group than in the control group(creatine kinase: 1 257 (682, 2 202) U/L vs. 1 737(794, 2 816)U/L, P =0.029; creatine kinase-MB: 123(75, 218)U/L vs.165(95, 288)U/L, P =0.010). The rate of CI-AKI after the procedure was significantly lower in the IPC group than in the control group(5.69%(7/123) vs. 14.06%(18/128), P =0.034). The rate of the one-year MACE was significantly lower in the IPC group than in the control group(7.32%(9/123) vs. 15.63% (20/128), P =0.040). Conclusion: The IPC strategy performed eight before PPCI can reduce myocardial ischemia- reperfusion injury, decline the rates of CI-AKI and one-year MACE significantly in STEMI patients, thus has a significant protective effect on heart and kidney in STEMI patients.

The objective of this study was to determine the effect of a home-based exercise program on fatigue, anxiety, quality of life (QoL), and immune function of thyroid cancer patients taking thyroid hormone replacement after thyroidectomy. This quasi-experimental study with a non-equivalent control group included 43 outpatients taking thyroid hormone replacement after thyroidectomy (22 in the experimental group and 21 in the control group). After education about the home-based exercise program, subjects in the experimental group underwent 12 weeks of aerobic, resistance, and flexibility exercise. A comparative analysis was conducted between the two groups. Patients in the experimental group were significantly less fatigued or anxious (p < 0.01). They reported significantly improved QoL (p < 0.05) compared to those in the control group. Natural killer cell activity was significantly higher in the exercise group compared to that in the control group (p < 0.05). A home-based exercise program is effective in reducing fatigue and anxiety, improving QoL, and increasing immune function in patients taking thyroid hormone replacement after thyroidectomy. Therefore, such a home-based exercise program can be used as an intervention for patients who are taking thyroid hormone replacement after thyroidectomy.

To investigate the role of melatonin in calcium overload-induced heart injury.
 Methods: Thirty-two rats were divided into 4 groups: a control group (Control), a melatonin control group (Mel), a calcium overload group (CaP), and a calcium overload plus melatonin group (Mel+CaP). Isolated Sprague Dawley male rat hearts underwent Langendorff perfusion. Left ventricular developed pressure (LVDP) was calculated to evaluate the myocardial performance. Triphenyltetrazolium chloride staining was used to measure the infarct size of myocardium. Lactate dehydrogenase (LDH) activity in the coronary flow was determined. The expressions of caspase-3 and cytochrome c were determined by Western blot. The pathological morphological changes in myocardial fiber were analyzed by HE staining.
 Results: Compared with the control group, calcium overload significantly induced an enlarged infarct size (P<0.01), accompanied by the disordered arrangement of myocardial fiber, up-regulation of cytochrome c and caspase-3 (P<0.01), and the increased activity of LDH (P<0.01). These effects were significantly attenuated by 10 μmol/L melatonin (P<0.01).
 Conclusion: Melatonin can alleviate calcium overload-induced heart injury.

Defining the impaction frequency and threshold force required for femoral impaction grafting in revision hip arthroplasty

PubMed Central

2011-01-01

Background and purpose The two most common complications of femoral impaction bone grafting are femoral fracture and massive implant subsidence. We investigated fracture forces and implant subsidence rates in embalmed human femurs undergoing impaction grafting. The study consisted of two arms, the first examining the force at which femoral fracture occurs in the embalmed human femur, and the second examining whether significant graft implant/subsidence occurs following impaction at a set force at two different impaction frequencies. Methods Using a standardized impaction grafting technique with modifications, an initial group of 17 femurs underwent complete destructive impaction testing, allowing sequentially increased, controlled impaction forces to be applied until femoral fracture occurred. A second group of 8 femurs underwent impaction bone grafting at constant force, at an impaction frequency of 1 Hz or 10 Hz. An Exeter stem was cemented into the neomedullary canals. These constructs underwent subsidence testing simulating the first 2 months of postoperative weight bearing. Results No femurs fractured below an impaction force of 0.5 kN. 15/17 of the femurs fractured at or above 1.6 kN of applied force. In the second group of 8 femurs, all of which underwent femoral impaction grafting at 1.6 kN, there was no correlation between implant subsidence and frequency of impaction. Average subsidence was 3.2 (1–9) mm. Interpretation It is possible to calculate a force below which no fracture occurs in the embalmed human femur undergoing impaction grafting. Higher impaction frequency at constant force did not reduce rates of implant subsidence in this experiment. PMID:21689068

The number of patients receiving total knee arthroplasty (TKA) has been rising every year due to the aging population and the obesity epidemic. Post-operative rehabilitation is important for the outcome of TKA. A series of 34 patients who underwent primary unilateral TKA was retrospectively collected and divided into either exercise group (n = 16) and control group (n = 18). The exercise group underwent a 24-week course of circuit training beginning 3 months after total knee arthroplasty (TKA). The effect of circuit training on TKA patients in terms of motion analysis, muscle strength testing, Knee injury and Osteoarthritis Outcomes Score (KOOS) questionnaire and patient-reported outcome measurement Short-Form Health Survey (SF-36) at the pre-operation, pre-exercise, mid-exercise, and post-exercise. Motion analysis revealed the stride length, step velocity, and excursion of active knee range of motion significantly improved in the exercise group when compared to those in the control group. KOOS questionnaire showed a greater improvement in pain, ADL, and total scores in the exercise group. The SF-36 questionnaire revealed a significant improvement in general health, bodily pain, social function, and physical components score in the exercise group. The post-operative circuit training intervention can facilitate recovery of knee function and decrease the degree of pain in the TKA and might be considered a useful adjunct rehabilitative modality. The ultimate influence of circuit training on TKA needs further a prospective randomized clinical trial study and long-term investigation. NCT02928562.

Endoscopic thyroidectomy for minimally invasive thyroid surgery has been widely applied in the past decade. The present study aimed to evaluate the effects of single-port access transaxillary totally endoscopic thyroidectomy on the postoperative outcomes and functional parameters, including quality of life and cosmetic result in patients with papillary thyroid carcinoma (PTC). Seventy-five patients with PTC who underwent endoscopic thyroidectomy via a single-port access transaxillary approach were included (experimental group). A total of 123 patients with PTC who were subjected to conventional open total thyroidectomy served as the control group. The health-related quality of life and cosmetic and satisfaction outcomes were assessed postoperatively. The mean operation time was significantly increased in the experimental group. The physiological functions and social functions in the two groups were remarkably augmented after 6 months of surgery. However, there was no significant difference in the scores of speech and taste between the two groups at the indicated time of 1 month and 6 months. In addition, the scores for appearance, satisfaction with appearance, role-physical, bodily pain, and general health in the experimental group were better than those in the control group at 1 month and 6 months after surgery. The single-port access transaxillary totally endoscopic thyroidectomy is safe and feasible for the treatment of patients with PTC. The subjects who underwent this technique have a good perception of their general state of health and are likely to participate in social activities. It is worthy of being clinically used for patients with PTC.

Background The impact of personalized exercise training and a healthy dietary lifestyle in healthy volunteers on coronary flow reserve and cardiovascular function remains to be investigated in a controlled study setting. Purpose To examine the effects of a Mediterranean-inspired diet combined with regular physical exercise (standard) and a personalized supervised exercise program (DAPS) on coronary flow reserve and cardiovascular function. Results The number of males were 10 (59%) and 9 (47%) and mean age was 54 ± 12 and 55 ± 5 years in standard versus DAPS group, respectively. Primary outcomes were in addition to improved body composition and aerobic capacity, increased TDE-CFR (5.0%, CI:1.62,8.64, p = 0.005) and left ventricle ejection fraction (LVEF) during hyperemia (10.2%, CI:1.62,19.4, p = 0.022) in DAPS adjusted for the control period. Also, plasma fibrinogen decreased (−12.1%, CI:-22.0,–0.92, p = 0.035) in the DAPS group. Secondary outcomes, after adjusting DAPS intervention effects for the standard-training period, TDE-CFR and hyperemic LVEF remained significantly improved. Materials and Methods This randomized, controlled clinical trial (URL: http://www.clinicaltrials.gov NCT02713724) included 36 healthy volunteers who underwent exercise ECG before randomization to standard or DAPS groups. Standard-group was given gym-membership with limited instructions and general dietary advice. DAPS-group received personalized supervised exercise programs and more detailed dietary advice with regular contact with a personal trainer. Effects were evaluated after 3 months. All participants underwent coronary flow reserve by transthoracic ultrasound (TDE-CFR), blood marker analysis and examinations of vascular function. Standard-group was evaluated pre-control, post-control (=pre-intervention) and post-intervention. DAPS-group was examined at pre-intervention and post-intervention. Conclusions A personalized supervised training- and diet program improves cardiovascular status in healthy subjects with a physically inactive lifestyle and may be a promising approach for cardiovascular prevention in the general population.

Ulnar collateral ligament (UCL) reconstructions are relatively common among professional pitchers in Major League Baseball (MLB). To the authors' knowledge, there has not been a study specifically analyzing pitching velocity after UCL surgery. These measurements were examined in a cohort of MLB pitchers before and after UCL reconstruction. There is no significant loss in pitch velocity after UCL reconstruction in MLB pitchers. Cohort study; Level of evidence, 3. Between the years 2008 to 2010, a total of 41 MLB pitchers were identified as players who underwent UCL reconstruction. Inclusion criteria for this study consisted of a minimum of 1 year of preinjury and 2 years of postinjury pitch velocity data. After implementing exclusion criteria, performance data were analyzed from 28 of the 41 pitchers over a minimum of 4 MLB seasons for each player. A pair-matched control group of pitchers who did not have a known UCL injury were analyzed for comparison. Of the initial 41 players, 3 were excluded for revision UCL reconstruction. Eight of the 38 players who underwent primary UCL reconstruction did not return to pitching at the major league level, and 2 players who met the exclusion criteria were omitted, leaving data on 28 players available for final velocity analysis. The mean percentage change in the velocity of pitches thrown by players who underwent UCL reconstruction was not significantly different compared with that of players in the control group. The mean innings pitched was statistically different only for the year of injury and the first postinjury year. There were also no statistically significant differences between the 2 groups with regard to commonly used statistical performance measurements, including earned run average, batting average against, walks per 9 innings, strikeouts per 9 innings, and walks plus hits per inning pitched. There were no significant differences in pitch velocity and common performance measurements between players who returned to MLB after UCL reconstruction and pair-matched controls.

Upper limb impairments can occur in patients with multiple sclerosis, affecting daily living activities; however there is at present no definite agreement on the best rehabilitation treatment strategy to pursue. Moreover, motor training has been shown to induce changes in white matter architecture in healthy subjects. This study aimed at evaluating the motor behavioral and white matter microstructural changes following a 2-month upper limb motor rehabilitation treatment based on task-oriented exercises in patients with multiple sclerosis. Thirty patients (18 females and 12 males; age=43.3 ± 8.7 years) in a stable phase of the disease presenting with mild or moderate upper limb sensorimotor deficits were randomized into two groups of 15 patients each. Both groups underwent twenty 1-hour treatment sessions, three times a week. The "treatment group" received an active motor rehabilitation treatment, based on voluntary exercises including task-oriented exercises, while the "control group" underwent passive mobilization of the shoulder, elbow, wrist and fingers. Before and after the rehabilitation protocols, motor performance was evaluated in all patients with standard tests. Additionally, finger motor performance accuracy was assessed by an engineered glove. In the same sessions, every patient underwent diffusion tensor imaging to obtain parametric maps of fractional anisotropy, mean diffusivity, axial diffusivity, and radial diffusivity. The mean value of each parameter was separately calculated within regions of interest including the fiber bundles connecting brain areas involved in voluntary movement control: the corpus callosum, the corticospinal tracts and the superior longitudinal fasciculi. The two rehabilitation protocols induced similar effects on unimanual motor performance, but the bimanual coordination task revealed that the residual coordination abilities were maintained in the treated patients while they significantly worsened in the control group (p=0.002). Further, in the treatment group white matter integrity in the corpus callosum and corticospinal tracts was preserved while a microstructural integrity worsening was found in the control group (fractional anisotropy of the corpus callosum and corticospinal tracts: p=0.033 and p=0.022; radial diffusivity of the corpus callosum and corticospinal tracts: p=0.004 and p=0.008). Conversely, a significant increase of radial diffusivity was observed in the superior longitudinal fasciculi in both groups (p=0.02), indicating lack of treatment effects on this structure, showing damage progression likely due to a demyelination process. All these findings indicate the importance of administering, when possible, a rehabilitation treatment consisting of voluntary movements. We also demonstrated that the beneficial effects of a rehabilitation treatment are task-dependent and selective in their target; this becomes crucial towards the implementation of tailored rehabilitative approaches.

The closure of a cystic duct during cholecystectomy by means of radiofrequency is still controversial. We report our preliminary experimental results with the use of LigaSure™ on common bile duct in rats. Thirty Wistar rats weighing 70 to 120 g were employed for this study. The animals were all anesthetized with intraperitoneal ketamine and then divided into three groups. The first group (10 rats, Group C) underwent only laparotomy and isolation of the common bile duct. The second (10 rats, Group M) underwent laparotomy and closure of the common bile duct (CBD) with monopolar coagulation. The third group (10 rats, Group L) underwent laparotomy and sealing of the common bile duct with two application of LigaSureTM. Afterwards, all rats were kept in comfortable cages and were administered dibenzamine for five days. They were all sacrificed on day 20. Through a laparotomy, the liver and bile duct were removed for histological examination. Blood samples were obtained to dose bilirubin, amylase and transaminase levels. Mortality rate was 0 in the control group (C), 3/10 rats in group M and 0 in group L. In group L, the macroscopic examination showed a large choledochocele (3-3.5 × 1.5 cm) with few adhesions. At the histological examination there was optimal sealing of the common bile duct in 9/10 rats. In group M, 2/10 rats had liver abscesses, 3/10 rats had choledochocele and 5/10 rats, biliary peritonitis. There was intense tissue inflammation and the dissection was difficult. Analyses of blood samples showed an increase in total bilirubin, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in groups M and L. The preliminary results of our study confirm that radiofrequency can be safely used for the closure of the common bile duct. The choledochocele obtained with this technique could represent a good experimental model. These results could be a further step for using the LigaSureTM in clipless cholecystectomy.

Among people who are hospitalised for community-acquired pneumonia, does an inpatient exercise-based rehabilitation program improve functional outcomes, symptoms, quality of life and length of hospital stay more than a respiratory physiotherapy regimen? Randomised trial with concealed allocation, intention-to-treat analysis and blinding of some outcomes. Forty-nine adults hospitalised for community-acquired pneumonia. The experimental group (n=32) underwent a physical training program that included warm-up, stretching, peripheral muscle strength training and walking at a controlled speed for 15 minutes. The control group (n=17) underwent a respiratory physiotherapy regimen that included percussion, vibrocompression, respiratory exercises and free walking. The intervention regimens lasted 8 days. The primary outcome was the Glittre Activities of Daily Living test, which assesses the time taken to complete a series of functional tasks (eg, rising from a chair, walking, stairs, lifting and bending). Secondary outcomes were distance walked in the incremental shuttle walk test, peripheral muscle strength, quality of life, dyspnoea, lung function, C-reactive protein and length of hospital stay. Measures were taken 1 day before and 1 day after the intervention period. There was greater improvement in the experimental group than in the control group on the Glittre Activities of Daily Living test (mean between-group difference 39 seconds, 95% CI 20 to 59) and the incremental shuttle walk test (mean between-group difference 130 m, 95% CI 77 to 182). There were also significantly greater improvements in quality of life, dyspnoea and peripheral muscle strength in the experimental group than in the control group. There were no between-group differences in lung function, C-reactive protein or length of hospital stay. The improvement in functional outcomes after an inpatient rehabilitation program was greater than the improvement after standard respiratory physiotherapy. The exercise training program led to greater benefits in functional capacity, peripheral muscle strength, dyspnoea and quality of life. ClinicalTrials.gov, NCT02103400.

In this randomized controlled study, we investigated the effects of autologous Hemobag blood transfusion (AHBT) and allogenic blood transfusion (ABT) in off-pump coronary artery bypass (OPCAB) surgery. Sixty patients who underwent surgery between February 2008 and August 2008 were randomized into 2 groups. The AHBT group (n = 30) consisted of patients who received autologous Hemobag blood transfusion, and the ABT group (n = 30) consisted of patients who received allogenic blood transfusion. All patients underwent OPCAB via sternotomy. The time to extubation, chest tube drainage volume, postoperative white blood cell counts, amount of blood transfusion, sedimentation rate, C-reactive protein concentration, postoperative temperature, and the presence of atelectasis were recorded in the intensive care unit. Intraoperative bleeding and fluid resuscitation were similar in the 2 groups (P > .05); however, there were significant decreases in postoperative blood loss, extubation period, postoperative white cell counts, sedimentation rate, incidence of atelectasis, C-reactive protein, and fever in the AHBT group compared with the ABT group (P < .05). The rate of atrial fibrillation in the AHBT group tended to be lower than in the ABT group. Autologous blood transfusion in OPCAB may be beneficial in certain cardiac surgery patients; however, these beneficial effects require further study to be proved.

Bariatric surgery can lead to vitamin deficiencies. We aimed to assess the changes in blood vitamin concentrations in patients who were taking predefined supplements after gastric bypass surgery. A total of 29 patients underwent gastric bypass and 24 unmatched controls underwent lifestyle intervention in a prospective, nonrandomized trial. The patients in the surgical group received multivitamin, iron, calcium, vitamin D, and vitamin B(12) supplements. No supplements were prescribed to the lifestyle group. The median body mass index decreased from 46 to 32 kg/m(2) after surgery and from 40 to 39 kg/m(2) after lifestyle intervention. Of the 53 included patients, 50 completed the 1-year follow-up examination (94%). Compared with the lifestyle patients, the surgical patients had increased vitamin B(6), folic acid, vitamin B(12), and lipid-adjusted vitamin E (P <.02 for each) concentrations but decreased vitamin A concentrations (P <.01) during follow-up. No significant difference between the 2 groups was found for vitamin B(1), vitamin C, or 25-hydroxyvitamin D. Most surgical patients reported taking their supplements. Gastric bypass patients adhering to a set of dietary supplements had mostly stable or increased vitamin concentrations compared with both their baseline values and the changes in a nonsurgical control group.

Imbalance in shoulder-rotator muscles has been considered a risk factor for injuries in handball. Strength training programs (STPs) may play an important preventive role. To verify the effects of an STP using elastic bands on shoulder muscles and ball-throwing speed. Randomized and prospective controlled trial. Exercise physiology laboratory. Thirty-nine female handball players were randomly assigned to an experimental (EG, n = 21, 15.3 ± 1.1 y) or a control (CG, n = 18, 15.0 ± 0.8 y) group. The EG performed the STP with elastic-band progressive exercises for 6 wk before regular handball training, and the CG underwent only their regular training. Before and after the STP, both groups underwent a ball-throwing-speed test and isokinetic test to assess shoulder internal- (IR) and external-rotator muscle performance. Average power values for IR muscles presented a significant group-vs-time interaction effect (F = 3.9, P = .05); EG presented significantly higher values after the STP (P = .03). Ball speed presented higher values in EG after the STP in standing (P = .04) and jumping (P = .03) throws. IR peak-torque values and balance in shoulder-rotator muscles presented no group-vs-time interaction effect. STP using elastic bands performed for 6 wk was effective to improve muscle power and ball speed for young female handball players.

The purpose of the study was to determine the advantages and disadvantages of prophylactic/extended colectomy (subtotal colectomy) in patients with Lynch syndrome who manifest colorectal cancer. A retrospective cohort using Creighton University's hereditary cancer database was used to identify cases and controls. Cases are patients who underwent subtotal colectomy, either with no colorectal cancer diagnosis (prophylactic) or at diagnosis of first colorectal cancer; controls for these 2 types of cases were, respectively, patients who underwent no colon surgery or those having limited resection at time of diagnosis of first colorectal cancer. The Kaplan-Meier and proportional hazard regression models from the Statistical Analysis Software program was used to calculate the difference in survival, time to subsequent colorectal cancer, and subsequent abdominal surgery between cases and controls. The event-free survival of our study did not reach 50%, so we used the event-free survival at 5 years as our parameter to compare the 2 groups. The event-free survival for subsequent colorectal cancer, subsequent abdominal surgery, and death was 94%, 84%, and 93%, respectively, for cases and 74%, 63%, and 88%, respectively, for controls. Times to subsequent colorectal cancer and subsequent abdominal surgery were significantly shorter in the control group (P < .006 and P < .04, respectively). No significant difference was identified with respect to survival time between the cases and controls. Even though no survival benefit was identified between the cases and controls the increased incidence of metachronous colorectal cancer and increased abdominal surgeries among controls warrant the recommendation of subtotal colectomy in patients with Lynch syndrome.

Arthroscopic surgery in borderline dysplastic hips remains controversial, but the role of the ligamentum teres (LT) has not been studied in this setting. Borderline dysplastic patients with LT tears have worse short-term outcomes than those without LT tears. Cohort study; Level of evidence, 3. Data were prospectively collected on patients who underwent arthroscopic surgery between February 2008 and April 2014. The inclusion criteria were borderline dysplasia (lateral center-edge angle [LCEA], 18°-25°) and labral tears; arthroscopic treatments including labral preservation and capsular plication; and preoperative patient-reported outcome scores including the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sport-Specific Subscale, and visual analog scale for pain. Patients were excluded for preoperative Tönnis osteoarthritis grade >0, workers' compensation claims, previous ipsilateral hip surgery and conditions, or frank dysplasia (LCEA <18°). Patients with LT tears were pair-matched to patients without tears for sex, age at surgery ±10 years, body mass index (<30 kg/m 2 vs ≥30 kg/m 2 ), labral treatment type, and microfracture. Of 68 eligible patients, 63 (93%) had a minimum 2-year follow-up, and 30 (48%) had LT tears. Twenty patients in each group were pair-matched. The mean follow-up time was 54.3 months (range, 24.2-83.8 months) for the LT tear group and 38.6 months (range, 24.6-70.6 months) for the control group ( P = .002). Ninety percent were female. There were no significant differences regarding demographics or intra-operative procedures. The LT tear group trended toward lower postoperative mHHS ( P = .09) and NAHS ( P = .09) values. Mean satisfaction was 8.1 for the LT tear group and 7.9 for the control group. Preoperative and follow-up scores were not significantly different between the groups. The LT tear group had 5 revisions, with 1 revision in the control group. Three patients (15%) in the LT tear group underwent total hip arthroplasty (THA); no patients in the control group required THA. In borderline dysplastic patients undergoing hip arthroscopic surgery with labral treatment and capsular plication, LT tears may indicate advanced instability and portend slightly inferior outcomes when compared with a match-controlled group. Borderline dysplastic patients with LT tears may have increased propensities toward revision arthroscopic surgery and conversion to THA. LT tears in these patients may warrant consideration for additional procedures including periacetabular osteotomy and LT reconstruction.

[Purpose] The objective of this study was to investigate the effects of spinal support device (SSD) on pain and hamstring extensibility in patients with non-specific low back pain (NSLBP). [Subjects and Methods] 20 patients with NSLBP were recruited and randomly assigned to either the SSD group or the control group. In the SSD group, SSD was applied; in the control group, bed rest in supine position was performed. Both groups underwent treatment 20 min/day, 3 times a week, for a duration of 4 weeks. To assess the hamstring extensibility, sit and reach test (SRT) was performed. To assess pain pressure threshold (PPT) of the sacroiliac joint, a pressure algometer was used. Visual analog scale (VAS) was used to quantify pain. [Results] The SSD group showed a significant improvement in sacroiliac joint pain with increased VAS, and the control group showed a significantly increased VAS after intervention. In the SSD group, VAS was significantly increased, but SRT was not changed compared with the control group. [Conclusion] These results demonstrated that an application of SSD effectively attenuates low back pain. Therefore, SSD may be a suitable intervention for pain control in patients with NSLBP.

Background. Parasternal block and transcutaneous electrical nerve stimulation (TENS) have been demonstrated to produce effective analgesia and reduce postoperative opioid requirements in patients undergoing cardiac surgery. Objectives. To compare the effectiveness of TENS and parasternal block on early postoperative pain after cardiac surgery. Methods. One hundred twenty patients undergoing cardiac surgery were enrolled in the present randomized, controlled prospective study. Patients were assigned to three treatment groups: parasternal block, intermittent TENS application, or a control group. Results. Pain scores recorded 4 h, 5 h, 6 h, 7 h, and 8 h postoperatively were lower in the parasternal block group than in the TENS and control groups. Total morphine consumption was also lower in the parasternal block group than in the TENS and control groups. It was also significantly lower in the TENS group than in the control group. There were no statistical differences among the groups regarding the extubation time, rescue analgesic medication, length of intensive care unit stay, or length of hospital stay. Conclusions. Parasternal block was more effective than TENS in the management of early postoperative pain and the reduction of opioid requirements in patients who underwent cardiac surgery through median sternotomy. This trial is registered with Clinicaltrials.gov number NCT02725229. PMID:27445610

Despite pharmacological treatment, chemotherapy-induced nausea and vomiting (CINV) are observed in patients. This quasi-randomized controlled pilot study evaluated the feasibility and preliminary effects of massage and inhalation aromatherapies on chemotherapy-induced acute nausea/vomiting. Seventy-five patients with breast cancer were randomly grouped into 1 of 3 groups: massage (n = 25), inhalation (n = 25), and control (n = 25). The patients in the massage group received 20-minute aromatherapy foot massage, whereas those in the inhalation group received 3-minute inhalation aromatherapy before their second, third, and fourth chemotherapy cycles. The control group underwent only the routine treatment. A nausea, vomiting, and retching patient follow-up form was used to evaluate nausea severity by visual analog scale and frequency of vomiting and retching. The incidence of nausea and retching was significantly higher in the control group than in the other groups in the third and fourth chemotherapy cycles (P < .001). Furthermore, in these 2 cycles, the incidence of nausea and retching was significantly lower in the massage group than in the inhalation group (P < .001). Nausea severity was significantly lower among patients in the massage and inhalation groups than in the control group in all 3 cycles (P < .001). Nausea severity was significantly lower in the massage and inhalation aromatherapy groups than in the control group. Nausea and retching incidence was reduced in the aromatherapy groups compared with that in the control group. Nonpharmacological approaches are recommended for managing CINV. Massage and inhalation aromatherapy seems promising regarding the management of CINV.

Epidemiological screening to examine possible ultraviolet-induced ocular changes and pathologies in Austrian farmers. The study was performed on behalf of the Austrian farmer insurance (Sozialversicherungsanstalt der Bauern). Randomly selected farmers and office workers as controls, both at the age of 35-55 years, underwent ophthalmic screening examinations. All subjects underwent complete ophthalmic examinations by slit lamp examination and Schirmer's test 1. A survey, regarding personal habits in the sun, was also conducted. Three hundred and ninety-two subjects underwent ophthalmic examinations of whom 297 were farmers and 95 were controls. Due to the survey, 89.7% of the farmers claimed to protect themselves from the sun during work. From these subjects, 83.7% wear a head protection, 71.0% wear sunglasses, and 54.4% usually work in the shade. There were significant differences in lid (p = 0.021) and conjunctival pathologies (p < 0.0001) between farmers and controls. Austrian farmers are at a higher risk for developing lid and conjunctival tumours which require treatment at some point. We believe that the study group was too young to show significant differences within the lens and the posterior pole. A 5-year follow-up is planned. Copyright 2010 S. Karger AG, Basel.

To assess cut-off value of creatinine and glomerular filtration rate for augmentation cystoplasty (AC) in paediatric age-group. Data of all paediatric-patients (<18 years) with small capacity bladder, in whom AC was advised between 2005-2015 were reviewed. All patients were divided in two-groups, AC-group and control-group (without AC). Creatinine and e-GFR were assessed at the time of surgery, at 6 months and at last follow-up. Renal function deterioration was defined as increase in creatinine by ≥25% from baseline value or new-onset stage-3 CKD or worsening of CKD stage with pre-operative-CKD stage-3. ROCs were plotted using creatinine and e-GFR for AC. A total of 94 patients with mean-age 8.9 years were included. The mean creatinine and e-GFR were 1.33mg/dL and 57.68mL/min respectively. Out of 94 patients, AC was performed in 45 patients and in the remaining 49 patients AC was not done (control-group), as they were not willing for the same. Baseline patient's characteristics were comparable in both Groups. 22 underwent gastro-cystoplasty (GC) and 25 underwent ileo-cystoplasty (IC). Decline in renal function was observed in 15 (33.3%) patients of AC-group and in 31 (63.3%) patients of control-group. Patients having creatinine ≥1.54mg/dL (P=0.004, sensitivity (S) 63.6% and specificity (s) 90.5%) at baseline and e-GFR ≤46mL/min (P=0.000, S=100% and s=85.7%) at the time of surgery had significantly increased probability of renal function deterioration on follow-up after AC. e-GFR ≤46mL/min and creatinine ≥1.54mg/dL at time of surgery could serve as a predictor of renal function deterioration in AC in paediatric patients.

Worker safety education using models that identify and reinforce factors affecting behavior is essential. The present study aimed to determine the effect of safety education based on motivational interviewing on awareness of, attitudes toward, and engagement in worker safety in the glass production industry in Hamedan, Iran, in 2014. This was a quasi-experimental interventional study including a total of 70 production line workers at glass production facilities in Hamedan. The workers were randomly assigned to either an intervention or a control group, with 35 workers in each group. Participants in the control group received four one-hour safety education sessions, in the form of traditional lectures. Those in the intervention group received four educational sessions based on motivational group interviewing, which were conducted in four groups of eight to ten participants each. The instruments used included a researcher-developed questionnaire with checklists addressing safety awareness, and attitude and performance, which were completed before and 12 weeks after the intervention. The data were analyzed using descriptive statistics, independent and paired t-tests, and chi-squared tests. Having obtained the differences in scores before and after the intervention, we determined mean changes in the scores of awareness, attitude, and use of personal protective equipment among workers who underwent motivational group interviewing (3.74 ± 2.16, 1.71 ± 3.16, and 3.2 ± 1.92, respectively, p < 0.05). These scores were significantly greater than those of control workers who underwent traditional educational sessions (1.28 ± 1.93, 1.1 ± 3.07, and 0.2 ± 1.26, respectively). Our findings revealed that incorporation of motivational interviewing principles into safety education programs had the positive effect of enhancing workers' knowledge, attitude, and, particularly, implementation of safe behaviors. The application of this advisory approach is recommended to increase workplace safety and minimize occupational hazards in the work environment.

PurposeSurgical esophagectomy is the gold standard treatment of early-stage esophageal cancer. The procedure is complicated with significant morbidity; the most severe complication being the anastomotic leakage. Anastomotic fistulas are reported in 5–25% of cases and are mainly due to gastric transplant ischemia. Here, we report our experience of ischemic pre-conditioning using preoperative arterial embolization (PreopAE) before esophagectomy.Materials and MethodsThe medical records of all patients who underwent oncologic esophagectomy from 2008 to 2015 were retrospectively reviewed. Patients were divided into two groups: patients who received PreopAE, and a control group of patients who did not benefit from ischemic pre-conditioning. The targetmore » arteries selected for PreopAE were the splenic artery, left gastric artery, and right gastric artery. Evaluation of the results was based on anastomotic leakage, postoperative mortality, technical success of PreopAE, and complications related to the embolization procedure.ResultsForty-six patients underwent oncologic esophagectomy with PreopAE and 13 patients did not receive ischemic conditioning before surgery. Thirty-eight PreopAE were successfully performed (83%), but right gastric artery embolization failed for 8 patients. Anastomotic leakage occurred in 6 PreopAE patients (13%) and in 6 patients (46%) in the control group (p = 0.02). The mortality rate was 2% in the PreopAE group and 23% in the control group (p = 0.03). Eighteen patients suffered from partial splenic infarction after PreopAE, all treated conservatively.ConclusionPreoperative ischemic conditioning by arterial embolization before oncologic esophagectomy seems to be effective in preventing anastomotic leakage.« less

Gonadotropins used in controlled ovarian stimulation have been increasing in number. Beside the recombinant preparations such as rec-FSH, rec-LH and h-hMG human-derived preparations have entered the market. We decided to compare the effects of rec-FSH and HP-hMG with GnRHa on embryo quality and pregnancy outcome in women undergoing an IVF cycle. In this study, data of 87 patients who had applied to our center from 2007 to 2008 and who had met all inclusion criteria, were analyzed. The patients underwent controlled ovarian hyperstimulation with HP-hMG, rec-FSH following down-regulation with a GnRHa in a long protocol, selected according to determined criteria and acquired embryo via IVF transfer. Of the 87 patients, 44 were stimulated with rec-FSH and 43 with HP-hMG. Distribution of infertility causes was similar between the groups. Duration of gonadotropin administration (p=0.677, Student's t-test) and the total dose of gonadotropin received (p=0.392, Student's t-test) were similar between the two groups. The fertilization rate of the rec-FSH group was significantly higher than the HP-hMG group (p=0.001, Mann-Whitney U test). No significant differences were observed between the study groups in biochemical, clinical and ongoing pregnancy parameters. The higher oocyte yield with rec-FSH does not result in higher quality embryos. LH activity in combination with FSH activity positively affected the oocyte and embryo maturation. Therefore, when we consider the clinical and ongoing pregnancy rates there is no inferiority of HP-hMG in controlled ovarian stimulation.

Beside the recombinant preparations such as rec-FSH, rec-LH and h-hMG human-derived preparations have entered the market. We decided to compare the effects of rec-FSH and HP-hMG with GnRHa on embryo quality and pregnancy outcome in women undergoing an IVF cycle. Material and Methods In this study, data of 87 patients who had applied to our center from 2007 to 2008 and who had met all inclusion criteria, were analyzed. The patients underwent controlled ovarian hyperstimulation with HP-hMG, rec-FSH following down-regulation with a GnRHa in a long protocol, selected according to determined criteria and acquired embryo via IVF transfer. Results Of the 87 patients, 44 were stimulated with rec-FSH and 43 with HP-hMG. Distribution of infertility causes was similar between the groups. Duration of gonadotropin administration (p=0.677, Student’s t-test) and the total dose of gonadotropin received (p=0.392, Student’s t-test) were similar between the two groups. The fertilization rate of the rec-FSH group was significantly higher than the HP-hMG group (p=0.001, Mann-Whitney U test). No significant differences were observed between the study groups in biochemical, clinical and ongoing pregnancy parameters. Conclusion The higher oocyte yield with rec-FSH does not result in higher quality embryos. LH activity in combination with FSH activity positively affected the oocyte and embryo maturation. Therefore, when we consider the clinical and ongoing pregnancy rates there is no inferiority of HP-hMG in controlled ovarian stimulation. PMID:24591951

[Evaluation of the cosmetic effect of orbital endoimplantation after removal the eyeball].

The purpose of our study was to evaluate the cosmetic effect of endoimplantation after removal the eyeball. The removal of the globe creates anatomic and physiological alteration of the orbital tissue and orbital bones. A volume deficit occurs when an eye is enucleated. Deep upper lid sulcus, ptosis, lower lid laxity, and enophthalmus of the artificial eye together constitute the postenucleation socket syndrome, which creates an asymmetry of the face. The orbital prosthesis by placing it in the orbital cavity allows correcting volume deficit, so the implant with attached extraocular muscles, together with an artificial eye, creates an illusion of real eye. Forty patients were operated on in Clinic of Eye Diseases of Kaunas University of Medicine Hospital. Twenty patients underwent removal of the eye and procedure of orbital implant insertion (main group). Twenty patients had just an eyeball removal without insertion of an orbital implant (control group). There was a statistically significant difference in exophthalmometry data between main and control groups (14.20+/-2.73 vs. 10.35+/-1.23 mm, respectively; p<0.05). The motility of artificial eye laterally (4.30+/-1.66 mm), medially (3.65+/-1.23 mm), up (3.70+/-1.13 mm), and down (3.40+/-1.19 mm) in the main group was significantly better as compared to the control group (p<0.05), where motility of the artificial eye was 0.60+/-0.68 mm laterally, 0.70+/-0.92 mm medially, 0.30+/-0.66 mm up, and 0.30+/-0.47 mm down. Therefore, a much better symmetry, better movement of the artificial eye, and less severe form of postenucleation syndrome were observed in patients who underwent orbital endoimplantation after eyeball removal.

This research was undertaken with the purpose of testing two research hypotheses regarding the efficacy of 10% oral glucose solution on procedural pain associated with venepuncture and nasopharyngeal suctioning within three neonatal intensive care units (NICU). The hypotheses were formulated from previous conclusions reached by other researchers highlighting the efficacy of sucrose solutions on neonates' pain responses during minor painful procedures. A quasi-experimental trial utilising a time series design with one group was used. Data from a total of 90 neonates included 60 neonates who underwent a venepuncture and 30 neonates who underwent a nasopharyngeal suctioning procedure for clinical purposes. The neonate's pain response for each procedure was scored using the Neonatal Pain Assessment Scale (NPAS) on two separate occasions over three time periods. The pre-procedural score (T 0 ) when the neonate received no sucrose, the inter-procedural score (T 1 ) when the neonate was given 2ml of 10% glucose solution two minutes before the procedure (intervention group) or where oral glucose was withheld (control group) and the post-procedural score (T 2 ) being at the end of the procedure. The results showed the mean NPAS scores in response to venepuncture or nasopharyngeal suctioning were significantly lower in the intervention group than the control group. This showed that oral glucose (10%) had a positive effect on the pain response during venepuncture and nasopharyngeal suctioning procedures. Copyright © 2015 Elsevier Inc. All rights reserved.

Numerous investigations postulated that laryngopharyngeal reflux (LPR) is implicated in the pathogenesis of various upper airway inflammatory diseases as sinusitis or dacryostenosis. The presence of pepsin in tears might be confirmed the presuntive hypothesis of the arrival in the nasolacrimal ducts and precorneal tears film through the laryngopharyngeal reflux of either gastric acid or stomach secretions (pepsin) with inflammatory potentialities. The aim of this preliminary study was to identify the presence or absence of pepsin in the tears collected from children with a high suspicion of LPR who underwent 24-h pH (MII-pH) monitoring to confirm the disease. This study enrolled 20 patients suffering from symptoms of laryngopharyngeal reflux that underwent 24-h multichannel intraluminal impedance (MII)-pH monitoring to confirm the disease. The findings of the study group were compared with those of a control group of patients with negative pH monitoring. The quantitative analysis of human pepsin concentration in the tear samples was performed by ELISA method in both groups. Four children (20%) of the study group showed pepsin in the tears. All of the subjects belonging to the control group were negative for its presence. No difference differences in the total number of reflux episodes and the number of weakly basic reflux in the pepsin positive patients vs. pepsin negative children were present. 20% of the children with diagnosed LPR showed pepsin in the tears. Our specific investigation might provide information regarding sinusitis or dacryostenosis. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The aim of this study was to evaluate the effect of mirror therapy on arm and hand function in subacute stroke in patients. The study included 60 hemiparetic right-handed patients after ischemic stroke 8-10 weeks after onset. They underwent stationary comprehensive rehabilitation in the rehabilitation centre. They were divided into two randomly assigned groups: mirror (n=30) and control (n=30). For both groups, two subgroups were created: one that included patients with right arm paresis (n=15) and the other that included patients with left arm paresis (n=15). The mirror group received an additional intervention: training with a mirror for 5 days/week, 2 sessions/day, for 21 days. Each single session lasted for 15 min. The control group (n=30) underwent a conventional rehabilitation program without mirror therapy. To evaluate self-care in performing activities of daily living, the Functional Index 'Repty' was used. To evaluate hand and arm function, the Frenchay Arm Test and the Motor Status Score were used. Measurements were performed twice: before and after 21 days of applied rehabilitation. No significant improvement in hand and arm function in both subgroups in Frenchay Arm Test and Motor Status Score scales was observed. However, there was a significant improvement in self-care of activities of daily living in the right arm paresis subgroup in the mirror group measured using the Functional Index 'Repty'. Mirror therapy improves self-care of activities of daily living for patients with right arm paresis after stroke.

Pelvic organ prolapse (POP) among young women is a relatively rare disorder with a unique clinical background. The objective of our study was to investigate the relative risk factors for POP and the relationship between family history and POP development in young women. In a retrospective longitudinal study we investigated 26 young patients (age <45 years) who underwent POP surgery and compared them to a control group of 26 patients (age >55 years) who underwent similar surgery and were matched with regard to parity. All women were interviewed for family history of POP, POP surgery among first-degree relatives, and hernia repair. Family history of POP was five times more prevalent among women in the study group than in the control group (46 % vs. 8 %, P < 0.01). Moreover, POP surgery among the first-degree relatives was significantly more prevalent in the study group (23.1 % vs. 3.8 %, p < 0.05). The prevalence of a family history of POP in more than one first-degree relative (11.5 % vs. 3.84 %, p = 0.3) and the family history of hernia repair among first-degree relatives (11.5 % vs. 15.4 %) did not differ between the groups. A family history of POP is significantly more common in younger affected women than in older affected women. We suggest that future genetic studies should concentrate on this specific population.

A firm understanding of the preliminary assessment of a patient with neurological disorders is needed for ensuring optimal patient outcomes. The purpose of this study is to evaluate the effects of using e-learning on neurologic assessment knowledge, ability, and self-confidence among nurses. This study used a non-equivalent control group pretest-posttest design. Nurses working in the neurology and neurosurgery wards, Republic of Korea PARTICIPANTS: A convenience sample of 50 nurses was assigned to either the experimental group (n=24) or the control group (n=26). The experimental group participated in the self-directed e-learning program related to neurologic assessment, and control group underwent self-directed learning with handout. Knowledge, ability, and self-confidence were measured at pretest and posttest. There were no significant differences in knowledge (U=270, p=0.399) and self-confidence (U=241.5, p=0.171) between the two groups. Nurses in the experimental group showed higher neurologic assessment ability compared with those in the control group (U=199, p=0.028). Self-directed neurologic assessment e-learning induced improvement in the neurologic assessment ability among nurses. Self-directed e-learning can be applied for improving competencies in neurologic assessment. Copyright © 2017 Elsevier Ltd. All rights reserved.

Sixty cats which underwent an ovariohysterectomy were randomly allocated into four treatment groups. One group (controls) received no analgesics postoperatively, and the others received either a single dose of buprenorphine (0.006 mg/kg) intramuscularly, or pethidine (5 mg/kg) intramuscularly, or ketoprofen (2 mg/kg) subcutaneously. The analgesia obtained after each treatment was assessed by three measures. There were significant differences between the groups both for the requirement for intervention analgesia (P = 0.0008) and for the overall clinical assessment (P = 0.0003) with ketoprofen requiring least intervention analgesia and having the best overall clinical assessment, followed by buprenorphine then pethidine. The control group required the most intervention analgesia and had the worst overall clinical assessment. Visual analogue scale scoring for pain produced significant differences between the groups from one hour after the operation, with the cats which were given ketoprofen tending to have lower pain scores than the other groups.

Endoscopic submucosal dissection (ESD) is an accepted treatment for early esophageal carcinoma. However, resection of a large mucosal area, as with circumferential ESD, induces severe stricture formation. To evaluate the efficacy of cultured autologous epidermal cell sheets to prevent severe esophageal constriction after circumferential ESD. Animal study. University institute. Eight pigs underwent circumferential esophageal ESD while under general anesthesia. In 4 pigs, fabricated autologous epidermal cell sheets were endoscopically transplanted to the central ESD sites immediately after the ESD. The other 4 pigs underwent circumferential ESD only. Necropsy and histological assessment were performed at 1 and 2 weeks post-ESD. Weight gain, degree of mucosal constriction, and histological assessments. All pigs in the control group showed severe esophageal constriction after 2 weeks. The control and transplanted groups had weight gains of -10.3% and 0.3% (P = .03), respectively, and the mean degrees of constriction were 88% and 56% (P < .01), respectively. Early re-epithelialization and mild fibrosis in the muscularis were observed in the transplanted group. Animal study, small sample size. Fabricated autologous skin epidermal cell sheets would be useful in preventing severe esophageal constriction after circumferential ESD.

The aim of the study was to evaluate the predictive values of two novel urinary markers for bladder cancer: survivin and soluble-Fas (s-Fas). The study included 84 individuals divided in two groups. The first group contained 47 patients, who underwent transurethral bladder tumor resection and the second, control, group 20 patients with non-malignant conditions, who underwent cystoscopy and 17 health volunteers. Fresh, second morning voided urine was collected for measurement of s-Fas, survivin, BTA and for cytology. Sensitivity, specificity, positive and negative predictive values and accuracy were calculated. Bladder tumor patients had significantly higher survivin urine levels in comparison to the controls. Survivin correlated also with the tumor stage. Combination of survivin with BTA had a sensitivity of 86.4% but still lower than that of cystoscopy (97.8%). Only the specificity of the combination between survivin and BTA was higher than that of cystoscopy (86.4% and 75.6%, respectively). Survivin was a better marker for tumor detection than s-Fas and was better enough to discriminate cancer stage. Combination of survivin and BTA had a specificity of 86.4% to exclude bladder malignancy and the combination of s-Fas with survivin and BTA had a sensitivity of 93.6% to detect bladder cancer.

The objective of this study was to compare the prevalence of Bell's palsy in participants who underwent mastoidectomy (to treat chronic otitis media) and nonmastoidectomy participants (control). Using the national cohort study from the Korean Health Insurance Review and Assessment Service, mastoidectomy patients (2,045) and control participants (8,180) were matched 1:4 for age, sex, income, and region of residence. The prevalence of Bell's palsy in both the groups was measured from 0 to 10 years postoperation. In a sample of 1,025,340 Korean individuals, 7,070 were diagnosed or treated with Bell's palsy between 2002 and 2013; the annual incidence of Bell's palsy was 0.057%. The overall prevalence of Bell's palsy was three times higher in the mastoidectomy group (1.27%) than control group (0.49%) (p < 0.001). The prevalence of Bell's palsy was different between the two groups in postoperative 0 year: 0.78% for the mastoidectomy group versus 0.01% for the control group (p < 0.001). Although we could not verify the laterality, the prevalence of Bell's palsy was increased in chronic otitis media patients treated with mastoidectomy patients compared with controls, especially within a year after surgery.

The objective of this study is to evaluate maternal and neonatal outcomes associated with trial of labor after cesarean (TOLAC) in women with three prior cesarean delivery (CD) and at least one prior vaginal delivery. This is a retrospective study using data collected from clinical records of women three prior CD and at least one prior vaginal delivery who were referred to our unit. Maternal and perinatal outcomes were compared between women with three prior CD who underwent TOLAC and those who underwent planned repeated CD (i.e. control group). The primary outcome was a composite of maternal complications including at least one of the followings: need for blood transfusion, uterine rupture, hysterectomy, and admission to intensive care unit. Fifty singleton gestations with three prior CD at with at least one prior vaginal birth were analyzed. Of them, 10 accepted to undergo TOLAC. Of the 10 women who underwent TOLAC, nine had vaginal birth and one had CD for non-reassuring pattern. We found no significant differences in the primary outcome, in need for blood transfusion, in the incidence of uterine rupture, hysterectomy, and admission to intensive care unit comparing TOLAC group with controls. TOLAC in women with three prior CD and at least one prior vaginal delivery is a viable option and is not associated with higher risk of adverse maternal or fetal outcomes.

Fibroblastic proliferation of subconjunctival tissues remains a primary mechanism of failure in filtration surgery. Minimizing the surgical manipulation of episcleral tissues may reduce scarring. Laser sclerostomy surgery involves minimal tissue dissection, and is gaining attention as a method of potentially improving filter duration in high-risk cases. Twenty-five New Zealand rabbits underwent filtration surgery in one eye, and the fellow eye remained as the unoperated control. Ten rabbits underwent ab externo diode laser sclerostomy surgery, ten underwent ab interno diode sclerostomy surgery, and five had posterior sclerostomy procedures. Filtration failure was defined as a less-than-4-mmHg intraocular pressure (IOP) difference between the operative and control eyes. The mean time to failure for the ab externo, ab interno, and conventional posterior sclerostomy techniques measured 17.4 +/- 11.5, 13.1 +/- 6.7, and 6.0 +/- 3.1 days, respectively. In a comparison of the laser-treated groups with the conventional procedure, the time to failure was significantly longer (P = 0.02) for the ab externo filter. The mean ab interno sclerostomy duration was longer than the posterior lip procedure, but this difference was not statistically significant (P = 0.15). The overall level of IOP reduction was similar in the three groups. These data suggest that diode laser sclerostomy is a feasible technique in rabbits, and the ab externo approach resulted in longer filter duration than the conventional posterior lip procedure in this model.

On July 20, 2014, the first known case of Ebola virus disease (Ebola) in Nigeria, in a traveler from Liberia, led to an outbreak that was successfully curtailed with infection control, contact tracing, isolation, and quarantine measures coordinated through an incident management system. During this outbreak, most contacts underwent home monitoring, which included instructions to stay home or to avoid crowded areas if staying home was not possible. However, for five contacts with high-risk exposures, group quarantine in an observation unit was preferred because the five had crowded home environments or occupations that could have resulted in a large number of community exposures if they developed Ebola.

Thoracic radiation therapy (XRT) for cancer is associated with the development of significant coronary artery disease that may require coronary artery bypass grafting surgery (CABG). Contemporary acute surgical outcomes and long-term postoperative survival of patients with prior XRT have not been well characterised. This was a retrospective, single-centre study of patients with a history of thoracic XRT who required CABG and who were propensity matched against 141 controls who underwent CABG over the same time period. The objectives were to assess early CABG outcomes and long-term survival in patients with prior XRT. Thirty-eight patients with a history of previous thoracic XRT underwent CABG from 1994 to 2013. The median time from XRT exposure to surgery was 7.9 years (IQR: 2.5-18.4 years). Perioperative adverse events were similar in the XRT group and controls; however, there was a trends lower utilisation of internal mammary artery (IMA) grafts in the XRT group (89%vs98%, P=0.13). After a median postoperative follow-up of 5.4 years (IQR 0.9-9.4 years), no difference in long-term all-cause mortality was observed. Patients with prior thoracic XRT who undergo CABG have similar long-term all-cause mortality compared with controls. Isolated CABG after thoracic XRT is not associated with higher perioperative complications, but IMA graft use may be limited by prior XRT.

The aim of this research was to determine the effectiveness of resilience training upon ego-control and hardiness of the addicted persons. This was a semi-experimental study with pretest and posttest control groups which was conducted in Sari, Iran, during 2014-2015. Thirty persons were selected among 240 illicit drug users who underwent screening. Resilience training was performed in ten sessions for the experimental group. The Kobasa hardiness questionnaire and self-restraint scale (SRS) were used for data collection and multivariate covariance test was performed for data analysis. According to the data, ego-control and hardiness of participants were improved significantly by resilience training (P < 0.001). Resilience training is effective upon the rate of ego-control and self-restraint and hardiness. This method can be used in addiction treatment clinics and residential centers.

Diabetic peripheral neuropathy is a common and debilitating complication of diabetes mellitus. Although strict glycaemic control may reduce the risk of developing diabetic peripheral neuropathy, the neurological benefits of different insulin regimens remain relatively unknown. In the present study, 55 consecutive patients with type 1 diabetes mellitus underwent clinical neurological assessment. Subsequently, 41 non-neuropathic patients, 24 of whom were receiving multiple daily insulin injections (MDII) and 17 receiving continuous subcutaneous insulin infusion (CSII), underwent nerve excitability testing, a technique that assesses axonal ion channel function and membrane potential in human nerves. Treatment groups were matched for glycaemic control, body mass index, disease duration and gender. Neurophysiological parameters were compared between treatment groups and those taken from age and sex-matched normal controls. Prominent differences in axonal function were noted between MDII-treated and CSII-treated patients. Specifically, MDII patients manifested prominent abnormalities when compared with normal controls in threshold electrotonus (TE) parameters including depolarizing TE(10-20ms), undershoot and hyperpolarizing TE (90-100 ms) (P < 0.05). Additionally, recovery cycle parameters superexcitability and subexcitability were also abnormal (P < 0.05). In contrast, axonal function in CSII-treated patients was within normal limits when compared with age-matched controls. The differences between the groups were noted in cross-sectional analysis and remained at longitudinal follow-up. Axonal function in type 1 diabetes is maintained within normal limits in patients treated with continuous subcutaneous insulin infusion and not with multiple daily insulin injections. This raises the possibility that CSII therapy may have neuroprotective potential in patients with type 1 diabetes. Copyright © 2014 John Wiley & Sons, Ltd.

Multiparametric magnetic resonance imaging (MP-MRI) may improve the detection of clinically significant prostate cancer (PCa). To compare MP-MRI transrectal ultrasound (TRUS)-fusion targeted biopsy with routine TRUS-guided random biopsy for overall and clinically significant PCa detection among patients with suspected PCa based on prostate-specific antigen (PSA) values. This institutional review board-approved, single-center, prospective, randomized controlled trial (April 2011 to December 2014) included 130 biopsy-naive patients referred for prostate biopsy based on PSA values (PSA <20 ng/ml or free-to-total PSA ratio ≤0.15 and PSA <10 ng/ml). Patients were randomized 1:1 to the MP-MRI or control group. Patients in the MP-MRI group underwent prebiopsy MP-MRI followed by 10- to 12-core TRUS-guided random biopsy and cognitive MRI/TRUS fusion targeted biopsy. The control group underwent TRUS-guided random biopsy alone. MP-MRI 3-T phased-array surface coil. The primary outcome was the number of patients with biopsy-proven PCa in the MP-MRI and control groups. Secondary outcome measures included the number of positive prostate biopsies and the proportion of clinically significant PCa in the MP-MRI and control groups. Between-group analyses were performed. Overall, 53 and 60 patients were evaluable in the MP-MRI and control groups, respectively. The overall PCa detection rate and the clinically significant cancer detection rate were similar between the MP-MRI and control groups, respectively (64% [34 of 53] vs 57% [34 of 60]; 7.5% difference [95% confidence interval (CI), -10 to 25], p=0.5, and 55% [29 of 53] vs 45% [27 of 60]; 9.7% difference [95% CI, -8.5 to 27], p=0.8). The PCa detection rate was higher than assumed during the planning of this single-center trial. MP-MRI/TRUS-fusion targeted biopsy did not improve PCa detection rate compared with TRUS-guided biopsy alone in patients with suspected PCa based on PSA values. In this randomized clinical trial, additional prostate magnetic resonance imaging (MRI) before prostate biopsy appeared to offer similar diagnostic accuracy compared with routine transrectal ultrasound-guided random biopsy in the diagnosis of prostate cancer. Similar numbers of cancers were detected with and without MRI. ClinicalTrials.gov identifier: NCT01357512. Copyright © 2015 European Association of Urology. Published by Elsevier B.V.

To observe the effect of Cangfu Congxian Decoction (CCD) on oxidative stress in granulosa cells of polycystic ovary syndrome (PCOS) patients. Forty PCOS patients underwent in vitro fertilization-embryo transfer (IVF-ET) were assigned to the treatment group and the control group 1 according to random digit table, 20 in each group. Patients in the treatment group took CCD (200 mL, once in the morning and once in the afternoon) 2 months before IVF-ET, while those in the control group 1 took no Chinese medical decoction. Recruited were another 20 patients undergoing IVF-ET for tubal factors (as the control group 2). The clinical effect of IVF-ET were observed, including oocyte retrieval number, 2 pronuclear (2PN) fertilization rate, good quality embryo rate, clinical pregnancy rate, and ovarian hyperstimulation syndrome (OHSS) induced transplantation cancel rate. The expression of relative oxygen species (ROS) in granulosa cells was detected using cell immunofluorescence combined with confocal microscopy and FCM. Compared with the control group 1, occyte retrieval number, 2PN fertilization rate, and good quality embryo rate increased in the control group 2 and the treatment group (P <0. 05). OHSS induced transplantation cancel rate decreased in the control group 2 (P < 0.05). Fluorescence intensity of ROS decreased in the treatment group and the control group 2, as compared with the control group 1 (P < 0.01). CCD increased good quality embryo rate by down-regulating the expression of ROS protein in ovarian granulosa cells, and correcting in vivo oxidative stress.

The purpose of this study was to investigate the possible role of moderate and strenuous swimming training on plasma and cerebrospinal fluid (CSF) IL-6 (interleukin-6) levels during recovery from exhaustive exercise in rats. Wistar rats were divided into three groups: sedentary control (C), moderately trained (MT) and strenuously trained (ST). MT rats underwent swimming exercise for one hour/day and 5 days/week for 8 weeks. Animals in the ST group began swimming with 1 h/day and swimming duration was progressively increased by 30 min/wk, reaching 2.5 h/day by week 4 and stayed constant for an additional 4 weeks. After all animals underwent an acute exhaustive swimming exercise, animals were divided into 3 groups, and decapitated immediately, 24 and 48 hours after exhaustion to obtain tissue samples. Muscle citrate synthase activity, plasma and CSF IL-6 levels were determined. The citrate synthase activity was found to be higher in MT and ST groups compared to the C group. Although plasma IL-6 levels were found unaltered among all groups, the CSF IL-6 concentration was found to be increased 24 hours after exhaustive exercise of the ST group. We conclude that exercise training intensity is an important factor determining cerebrospinal IL-6 concentration after exhaustive exercise.

The potential contribution of psychological and anatomical changes to sexual dysfunction in female patients following short-term preoperative radiotherapy (5 x 5 Gy) and total mesorectal excision (TME) is not clear. Aim. In this study we assessed female sexual dysfunction in patients who underwent radiotherapy and TME for rectal cancer. Genital arousal was assessed using vaginal videoplethysmography. Sexual functioning was examined in four patients who had rectal cancer and underwent radiotherapy and TME. All investigations were done at least 15 months after treatment. The results were compared with an age-matched group of 18 healthy women. The patients and healthy controls showed comparable changes in vaginal vasocongestion during sexual arousal, though three out of four patients showed a lower mean spectral tension (MST) of the vaginal pulse compared with healthy controls. Subjective sexual arousal was equivalent between the two groups. In this study the changes of genital and subjective sexual arousal after erotic stimulus condition between patients and healthy controls were not different, though lower MST of the vaginal pulse was found in three out of four patients compared with healthy women. Additional work, however, must be performed to clarify the mechanisms of sexual dysfunction following treatment of rectal cancer.

The objective of this study was to determine the severity of attention deficit, hyperactivity, and impulsivity symptoms in patients with obstructive airway problems scheduled to undergo adenoidectomy or adenotonsillectomy operation. The effects of the surgical treatment on these symptoms will also be investigated in a case-control design. This prospective study included 63 patients (29 girls, 34 boys) who were operated on at the Department of Otorhinolaryngology, Dicle University Medical School, between January 2010 and May 2011 because of obstructive symptoms caused by adenoid or adenotonsillar hypertrophy. The age range of the patients was between 4 and 13 years. The control group consisted of 33 (17 girls, 16 boys) healthy children. Among the patients, 15 children underwent adenoidectomy because of adenoid hypertrophy; 13 patients had adenotonsillectomy because of adenotonsillar hypertrophy, and the remaining patients underwent adenotonsillectomy related with chronic or recurrent tonsillitis with adenoid hypertrophy. Based on the preoperative data, statistically significant difference was observed between the patient and control groups. The patients' attention deficit, hyperactivity, and impulsivity symptoms preoperatively and postoperatively have shown statistically significant differences. Attention deficit, hyperactivity, and impulsivity symptoms were common among the children who show signs of airway obstruction due to adenotonsillar hypertrophy. Adenoidectomy or adenotonsillectomy operations were both observed to be associated with improvement in these symptoms.

To determine whether a multiplex polymerase chain reaction (PCR)-based test could reduce the time required for initial pathogen identification in patients in an intensive care unit (ICU) setting. This double-blind, parallel-group randomized controlled trial** enrolled adults with suspected pulmonary or abdominal sepsis caused by an unknown pathogen. Both the intervention and control groups underwent the standard blood culture (BC) testing, but additional pathogen identification, based on the results of a LightCycler® SeptiFast PCR test, were provided in the intervention group. The study enrolled 37 patients in the control group and 41 in the intervention group. Baseline clinical and demographic characteristics were similar in both groups. The PCR-based test identified a pathogen in 10 out of 41 (24.4%) patients in the intervention group, with a mean duration from sampling to providing the information to the ICU of 15.9 h. In the control group, BC results were available after a significantly longer period (38.1 h). The LightCycler® SeptiFast PCR test demonstrated a significant reduction in the time required for initial pathogen identification, compared with standard BC. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Tramadol was found to be more effective than dexamethasone in post-operative pain control, with long-lasting relief of pain. This study aimed to compare the effects of pre-operative local injections of tramadol and dexamethasone on post-operative pain, nausea and vomiting in patients who underwent tonsillectomy. Sixty patients between 3-13 years of age who were planned for tonsillectomy were included in the study. Patients were divided into three groups. Group 1 was the control group. Patients in Group 2 received 0.3 mg/kg Dexamethasone and Group 3 received 0.1 mg/kg Tramadol injection to the peritonsillary space just before the operation. Patients were evaluated for nausea, vomiting, and pain. When the control and the dexamethasone groups were compared; there were statistically significant differences in pain scores at post-operative 15 and 30 min, whereas there was no statistically significant difference in pain scores at other hours. When the control and tramadol groups were compared, there was a statistically significant difference in pain scores at all intervals. When tramadol and dexamethasone groups were compared, there was no statistically significant difference in pain scores at post-operative 15 and 30 min, 1 and 2 h, whereas there was a statistically significant difference in pain scores at post-operative 6 and 24 h.

Bilateral balloon occlusion has been employed as a prophylactic measure in cases of placenta accretism prior to caesarean section with the aim of reducing blood loss and its associated morbidity/mortality. There is however no clear consensus on its efficacy in the current literature. The objective of this study was to assess the efficacy of bilateral balloon occlusion of the common iliac arteries (CIA) in reducing intra-operative morbidity in cases of placenta accretism. The databases of the pathology department and radiology interventional suite were reviewed over a nine year period. Fifty-two cases of confirmed placental accretism who underwent caesarean section with or without hysterectomy were identified and divided into two groups. Twenty-five cases had temporary occlusion of the common iliac arteries (CIA) during delivery and these were considered the study group. The reminder 27 cases did not have temporary occlusion of the CIA and were considered the control group. The two groups were compared based on gravidity, age group, post-operative haemoglobin, drop in haemoglobin, estimated blood loss (EBL), transfusion requirement and the histopathological sub-types of placenta accretism. There was no statistically difference between the study and the control groups regarding EBL, post-operative haemoglobin drop, transfusion requirement or in the placenta accretism histopathological subtype. Two cases in the study group had acute thromboembolic complications. Both groups had a single patient requiring a massive intra-operative transfusion. Our study was not able to detect a significant difference in blood loss or blood product requirement between patients who underwent CIA balloon in the setting of caesarean section for placenta accreta. This remains a challenging scenario requiring a multidisciplinary approach. © 2016 The Royal Australian and New Zealand College of Radiologists.

The aim was to test the effectiveness of early home-based group education on knowledge and communication about renal replacement therapy (RRT). We conducted a randomized controlled trial using a cross-over design among 80 end-stage renal disease (ESRD) patients. Between T0 and T1 (weeks 1-4) Group 1 received the intervention and Group 2 received standard care. Between T1 and T2 (weeks 5-8) Group 1 received standard care and Group 2 received the intervention. The intervention was a group education session on RRT options held in the patient's home given by social workers. Patients invited members from their social network to attend. Self-report questionnaires were used at T0, T1 and T2 to measure patients' knowledge and communication, and concepts from the Theory of Planned Behaviour such as attitude. Comparable questionnaires were completed pre-post intervention by 229 attendees. Primary RRT was registered up to 2 years post-intervention. Multilevel linear modelling was used to analyse patient data and paired t-tests for attendee data. Statistically significant increases in the primary targets knowledge and communication were found among patients and attendees after receiving the intervention. The intervention also had a significant effect in increasing positive attitude toward living donation and haemodialysis. Of the 80 participants, 49 underwent RRT during follow-up. Of these, 34 underwent a living donor kidney transplant, of which 22 were pre-emptive. Early home-based group education supports informed decision-making regarding primary RRT for ESRD patients and their social networks and may remove barriers to pre-emptive transplantation. © The Author 2015.

McCannel, Tara A., E-mail: TMcCannel@jsei.ucla.edu; McCannel, Colin A.

Purpose: We initially reported the radiation-attenuating effect of silicone oil 1000 centistokes for iodine 125. The purpose of this report was to compare the clinical outcomes in case patients who had iodine 125 brachytherapy with vitrectomy and silicone oil 1000 centistokes with the outcomes in matched control patients who underwent brachytherapy alone. Methods and Materials: Consecutive patients with uveal melanoma who were treated with iodine 125 plaque brachytherapy and vitrectomy with silicone oil with minimum 1-year follow-up were included. Control patients who underwent brachytherapy alone were matched for tumor size, location, and sex. Baseline patient and tumor characteristics and tumor response tomore » radiation, final visual acuity, macular status, central macular thickness by ocular coherence tomography (OCT), cataract progression, and metastasis at last follow-up visit were compared. Surgical complications were also determined. Results: Twenty case patients met the inclusion criteria. The average follow-up time was 22.1 months in case patients and 19.4 months in control patients. The final logMAR vision was 0.81 in case patients and 1.1 in control patients (P=.071); 8 case patients and 16 control patients had abnormal macular findings (P=.011); and the average central macular thickness by OCT was 293.2 μm in case patients and 408.5 μm in control patients (P=.016). Eleven case patients (55%) and 1 control patient (5%) had required cataract surgery at last follow-up (P=.002). Four patients in the case group and 1 patient in the control group experienced metastasis (P=.18). Among the cases, intraoperative retinal tear occurred in 3 patients; total serous retinal detachment and macular hole developed in 1 case patient each. There was no case of rhegmatogenous retinal detachment, treatment failure, or local tumor dissemination in case patients or control patients. Conclusions: With up to 3 years of clinical follow-up, silicone oil during brachytherapy for the treatment of uveal melanoma resulted in fewer abnormal maculas, lower central macular thickness on OCT, and a trend toward better final visual acuity in comparison with matched control patients who underwent brachytherapy alone.« less

To clarify the advantages and disadvantages of stenting as a bridge to surgery (BTS) by comparing the clinical features and outcomes of patients who underwent BTS with those of patients who underwent emergency surgery (ES). We assessed technical success, clinical success, surgical procedures, stoma formation, complications, clinicopathological features, and Onodera's prognostic nutritional index (OPNI) in patients who underwent BTS and those who underwent ES. Twenty-six patients underwent stenting, which was successful in 22 (BTS group). The remaining four patients with unsuccessful stenting underwent emergency surgery. A total of 22 patients underwent emergency surgery (ES group). The rates of technical and clinical success were 85.0 and 81.0 %, respectively. The proportion of patients able to be treated by laparoscopic surgery (P = 0.0001) and avoid colostomy (P = 0.0042) was significantly higher in the BTS group. Although the incidence of anastomotic leakage in the two groups was not significantly different, it was significantly reduced by colonoscopic evaluation of obstructive colitis (P = 0.0251). The mean number of harvested lymph nodes (P = 0.0056) and the proportion of D3 lymphadenectomy (P = 0.0241) were significantly greater in the BTS group. Perineural invasion (PNI) was noted in 59.1 and 18.2 % of the BTS group and ES group patients, respectively (P = 0.0053). OPNI and serum albumin decreased significantly after stenting (P = 0.0084). The advantages of stenting as a BTS were that it avoided colostomy and allowed for laparoscopic surgery and lymphadenectomy, whereas its disadvantage lay in the decreased PNI and OPNI levels. A larger study including an analysis of prognosis is warranted.

The aim of this study was to assess the correlation between fetal lateral ventricle width and biometric measurements. A prospective study on 335 fetuses, 101 fetuses with isolated mild ventriculomegaly and a control group of 234 fetuses with a normal US examination. All fetuses underwent a detailed brain ultrasound scan and a full biometric evaluation. To further compare biometric parameters, we matched, according to gestational week and gender, 91 fetuses from the study group to 91 fetuses from the control group. The mean gestational week during the exam was significantly different between the groups (29.6 weeks in the study group versus 28.3 in the control group, p = .001). The mean maternal age, obstetrical history, mode of conception, or fetal gender did not differ between the groups. After matching according to gestational age and fetal gender, the mean gestational week between the matched groups did not differ and was 29 + 5 weeks in both groups. The study group had significantly larger head circumference (p = .009), biparietal diameter (p < .001), femur length (p = .023), and estimated fetal weight (p = .024) compared with the control group. Isolated mild ventriculomegaly could be related to other larger fetal biometric measurements and does not necessarily mean a pathological condition.

Resection of hepatocellular carcinoma (HCC) is potentially curative; however, recurrence is common. To date, few or no effective adjuvant therapies have been adequately investigated. This study evaluates the efficacy of adjuvant iodine-131-lipiodol after hepatic resection through the experience of a single-center hepatobiliary service of managing this disease. All patients who underwent hepatic resection for HCC and received adjuvant iodine-131-lipiodol between January 1991 and August 2009 were selected for inclusion into the experimental group. A group composed of patients treated during the same time period without adjuvant iodine-131-lipiodol was identified through the unit's HCC surgery database for comparison. The endpoints of this study were disease-free survival and overall survival. Forty-one patients who received adjuvant iodine-131-lipiodol after hepatic resection were compared with a matched group of 41 patients who underwent hepatic resection only. The median disease-free and overall survival were 24 versus 10 months (P = 0.032) and 104 versus 19 months (P = 0.001) in the experimental and control groups, respectively. Rates of intrahepatic-only recurrences (73 vs. 37%; P = 0.02) and surgical and nonsurgical treatments for recurrences (84 vs. 56%; P = 0.04) were higher in the experimental group compared to the control group. The finding of this study corroborates the current evidence from randomized and nonrandomized trials that adjuvant iodine-131-lipiodol improves disease-free and overall survival in patients with HCC after hepatic resection. The lengthened disease-free survival after adjuvant iodine-131-lipiodol allows for further disease-modifying treatments to improve the overall survival.

To determine the safety and feasibility of percutaneous transhepatic cholangiography (PTC) and intraductal radiofrequency (RF) ablation combined with biliary stent placement for malignant biliary obstruction. Data from patients with unresectable malignant biliary obstruction who underwent PTC, intraductal RF ablation, and biliary stent placement (n = 12) or PTC and biliary stent placement only (control group; n = 14) were reviewed. Postoperative complications, jaundice remission, and stent patency were assessed. All procedures were successful. No severe complications (eg, biliary bleeding, perforation) occurred. Two experimental group patients developed cholangitis, which resolved with conservative treatment. The 1-week jaundice remission and 3-month stent patency rates were similar in both groups, but the 6-month stent patency rate was higher in the experimental group (P < .05). In the experimental group, one death occurred as a result of gastrointestinal hemorrhage (unrelated to stent placement) by 3 months, and there were two cases of recurrent jaundice by 6 months. The latter two patients underwent repeat PTC, ablation, and stent placement. In the control group, one death occurred as a result of hepatic failure caused by progressive jaundice at 3 months, and another death resulted from disseminated intravascular coagulation caused by jaundice recurrence at 138 days after stent placement. In addition, seven patients developed jaundice recurrence (50-151 d after stent placement). PTC and repeat stent placement were performed in these patients. Percutaneous transhepatic cholangiography and intraductal RF ablation combined with biliary stent placement for malignant biliary obstruction is safe and feasible and effectively prolongs stent patency time.

Experimental models have allowed inquiry into the pathophysiology of varicocele (VC) beyond that possible with human patients. A randomized controlled study in rats was designed to clarify the influence of the degree of left renal vein constriction on the development of adolescent VC. Fifty adolescent male Sprague-Dawley rats (Rattus norvegicus) were randomly assigned to five groups of 10: the experimental groups (I-IV) underwent partial ligation of left renal veins with 0.5-, 0.6-, 0.7-, and 0.8-mm diameter needles, respectively. The control group (V) underwent a sham operation. The diameter of the left spermatic vein (LSV) was measured at baseline and 30 days postoperatively. In addition, the lesion of the left kidney was examined with the naked eye and assessed by Masson's trichrome staining. VC was successfully induced in 2 (20%), 4 (40%), 7 (70%), and 10 (100%) rats in groups I-IV, respectively. The other rats failed to develop VCs primarily due to left renal atrophy. No VC was observed in group V. The postsurgical LSV diameters in VC rats in groups III and IV were 1.54 ± 0.16 and 1.49 ± 0.13 mm, respectively (P > 0.05), and their increments were 1.36 ± 0.10 and 1.31 ± 0.10 mm, respectively (P > 0.05). These results suggest that suitable constriction of the left renal vein is critical for adolescent VC development. In addition, the 0.8-mm diameter needle may be more suitable for inducing left renal vein constriction in adolescent rat models.

We determined and compared the effectiveness of low-level laser therapy (LLLT), therapeutic ultrasound (US) therapy, and extracorporeal shock wave therapy (ESWT) using magnetic resonance imaging (MRI). We performed a randomized, prospective, comparative clinical study. A total of 60 patients with a diagnosis of chronic plantar fasciitis were divided randomly into 3 treatment groups: group 1 underwent 15 sessions of LLLT (8 J/cm 2 ; 830 nm); group 2 underwent 15 sessions of continuous US (1 mHz; 2 W/cm 2 ); and group 3 underwent 3 sessions of ESWT (2000 shocks). All patients were assessed using the visual analog scale (VAS), heel tenderness index (HTI), American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, Roles-Maudsley score, and MRI before and 1 month after treatment. The primary efficacy success criterion was the percentage of decrease in heel pain of >60% from baseline at 1 month after treatment for ≥2 of the 3 heel pain (VAS) measurements. Significant improvement was measured using the mean VAS, AOFAS scale, and HTI scores for all 3 groups. The thickness of the plantar fascia had decreased significantly on MRI in all 3 groups. The treatment success rate was 70.6% in the LLLT group, 65% in the ESWT group, and 23.5% in the US group. LLLT and ESWT proved significantly superior to US therapy using the primary efficacy criterion (p = .006 and p = .012, respectively), with no significant difference between the LLLT and ESWT groups (p > .05). The treatment of chronic plantar fasciitis with LLLT and ESWT resulted in similar outcomes and both were more successful than US therapy in pain improvement and functional outcomes.

To better understand the changes in pulmonary physiology related to asthma severity following bronchoscopy, we performed scheduled pre- and post-procedure spirometry on subjects undergoing bronchoscopy in our research program. Control subjects and asthma subjects were recruited for bronchoscopy. On the day of bronchoscopy, subjects underwent spirometry pre-bronchoscopy and then up to three sets within 2 hour following the completion of bronchoscopy. A subset of patients had a second bronchoscopy after 2 weeks of treatment with oral prednisolone (40mg daily). A total of 92 subjects had at least one bronchoscopy (12 control subjects, 56 nonsevere asthma (NSA), 24 severe asthma (SA)). The SA and NSA groups had similar decreases in forced expiratory volume in 1 second (FEV1) (-20±13% vs.-19±16%, p = 0.92) and forced vital capacity (FVC) (-20±12% vs.-20±14%, p = 0.80), but no change in FEV1/FVC ratio. The control and NSA group had more rapid recovery of both FEV1 and FVC by 2 hour compared to the SA group (p = 0.01). In the subset of 36 subjects (22 NSA, 14 SA) who underwent a second bronchoscopy following the administration of oral prednisolone for 14 days, steroids resulted in more rapid recovery of lung function (p < 0.04). Following bronchoscopy the lung function of NSA subjects recovered more quickly than SA subjects. Treatment with oral corticosteroids was associated with a quicker recovery of FEV1 which suggests an inflammatory mechanism for these changes in lung compliance.

Objective The purpose of this study was to evaluate the feasibility of engaging in a series of larger studies measuring the effect of sacroiliac joint manipulation on walking kinematics using motion analysis technology. Methods Twelve college students engaged in a baseline 90-second gait analysis at 1.5 mph using infrared VICON cameras. Following this, they underwent a prone heel comparison test for functional leg length inequality. Upon examination, participants were then classified as follows: left short leg, right short leg, or no short leg. Participants in each of the 2 short leg branches of this study were then randomized to receive either chiropractic manipulative therapy to the posterior superior iliac spine on the short limb side or no manipulation. Recruitment was ongoing for this pilot study until 1 participant was recruited in each of the following 5 comparative study groups: left short leg—manipulation, left short leg—no manipulation (control 1), right short leg—manipulation, right short leg—no manipulation (control 2), and no short leg (control 3). All participants then underwent another 90-second gait analysis. Data were then grouped and submitted to a blinded biomechanist to determine if there were any unique biomechanical differences between the groups. Results No statistically significant differences were measured because of this being a pilot study with a small sample size. Conclusions The data from this study indicate that a series of larger studies with this design is feasible. PMID:24396314

Memory decline is a prevalent aspect of aging but may also be the first sign of cognitive pathology. Virtual reality (VR) using immersion and interaction may provide new approaches to the treatment of memory deficits in elderly individuals. The authors implemented a VR training intervention to try to lessen cognitive decline and improve memory functions. The authors randomly assigned 36 elderly residents of a rest care facility (median age 80 years) who were impaired on the Verbal Story Recall Test either to the experimental group (EG) or the control group (CG). The EG underwent 6 months of VR memory training (VRMT) that involved auditory stimulation and VR experiences in path finding. The initial training phase lasted 3 months (3 auditory and 3 VR sessions every 2 weeks), and there was a booster training phase during the following 3 months (1 auditory and 1 VR session per week). The CG underwent equivalent face-to-face training sessions using music therapy. Both groups participated in social and creative and assisted-mobility activities. Neuropsychological and functional evaluations were performed at baseline, after the initial training phase, and after the booster training phase. The EG showed significant improvements in memory tests, especially in long-term recall with an effect size of 0.7 and in several other aspects of cognition. In contrast, the CG showed progressive decline. The authors suggest that VRMT may improve memory function in elderly adults by enhancing focused attention.

AIM: To assess the effects of ischemic preconditioning (IPC, 10-min ischemia/10-min reperfusion) on steatotic liver mitochondrial function after normothermic ischemia-reperfusion injury (IRI). METHODS: Sixty male Sprague-Dawley rats were fed 8-wk with either control chow or high-fat/high-sucrose diet inducing > 60% mixed steatosis. Three groups (n = 10/group) for each dietary state were tested: (1) the IRI group underwent 60 min partial hepatic ischemia and 4 h reperfusion; (2) the IPC group underwent IPC prior to same standard IRI; and (3) sham underwent the same surgery without IRI or IPC. Hepatic mitochondrial function was analyzed by oxygraphs. Mitochondrial Complex-I, Complex-II enzyme activity, serum alanine aminotransferase (ALT), and histological injury were measured. RESULTS: Steatotic-IRI livers had a greater increase in ALT (2476 ± 166 vs 1457 ± 103 IU/L, P < 0.01) and histological injury following IRI compared to the lean liver group. Steatotic-IRI demonstrated lower Complex-I activity at baseline [78.4 ± 2.5 vs 116.4 ± 6.0 nmol/(min.mg protein), P < 0.001] and following IRI [28.0 ± 6.2 vs 104.3 ± 12.6 nmol/(min.mg protein), P < 0.001]. Steatotic-IRI also demonstrated impaired Complex-I function post-IRI compared to the lean liver IRI group. Complex-II activity was unaffected by hepatic steatosis or IRI. Lean liver mitochondrial function was unchanged following IRI. IPC normalized ALT and histological injury in steatotic livers but had no effect on overall steatotic liver mitochondrial function or individual mitochondrial complex enzyme activities. CONCLUSION: Warm IRI impairs steatotic liver Complex-I activity and function. The protective effects of IPC in steatotic livers may not be mediated through mitochondria. PMID:27217699

To study the potential effects of intensity modulated radiation therapy (IMRT) on clinical efficacy, oral mucosa reaction and immunological foundation; and to explore the effect of immunological changes on clinical efficacy and oral mucosa reaction in patients with nasopharyngeal carcinoma.
 Methods: A total of 200 patients with nasopharyngeal carcinoma, who came from First Department of Nasopharyngeal Radiotherapy, the First People's Hospital of Foshan from October 2008 to November 2011, were selected. The patients were treated with nasopharyngeal radiotherapy, and divided into an observation group and a control group (n=100 in each group). The control group underwent common conventional two-dimensional radiotherapy treatment, while the observation group underwent IMRT. The 5-year survival rates and recurrence rates were recorded at follow-up. After the radiotherapy, the oral mucosa in the patients were evaluated by the classification standard of acute radioactive mucositis by American Radiotherapy Oncology Group (RTOG), and the number of T lymphocyte subsets before and after treatment was detected.
 Results: There were significant difference in non-regional-recurrence survival rate, disease-free survival rate, local recurrence rate between the above 2 groups (all P<0.05), but no significant difference in the distant metastasis-free survival rate (P>0.05). The acute oral mucosa reactions of grade 1, 2, 3, 4 in the control group were 8.00%, 20.00%, 12.00%, 7.00%, respectively, and those were 7.00%, 22.00%, 15.00%, 1.00% respectively. There was no significant difference in the acute response of oral mucosa in grade 1, 2 and 3 in the 2 groups (all P>0.05), but there was significant difference in the grade 4 (P<0.05). There were significantly difference in CD8+, CD4+/ CD8+ and CD4+ T lymphocyte subsets before and after treatment in the above 2 groups (all P<0.01); there were also significantly difference after treatment between the observation group and the control group (all P<0.01).
 Conclusion: In the process of treatment in patients with nasopharyngeal carcinoma, the use of IMRT on the basis of chemotherapy is more effective than the conventional two-dimensional radiotherapy, which can reduce the proportion of grade 4 (severe) acute oral mucosa reaction. It may be related to the protective effect of IMRT on immune function in the patients.

BACKGROUND Hypothyroid has several effects on the cardiovascular system. Global myocardial performance index (MPI) is used in assessment of both left ventricular (LV) systolic and diastolic function. We compared MPI in hypothyroidism patients vs. normal control subjects. MATERIAL AND METHODS Eighty-two hypothyroid patients were divided into 2 groups: a subclinical hypothyroid (SH) group (n=50), and an overt hypothyroid (OH) group (n=32). The healthy control group (CG) constituted of 37 patients. TSH, FT3, and FT4, anti-TPO, anti-TG, insulin, lipid values, and fasting glucose levels were studied. All patients underwent an echocardiographic examination. Myocardial performance indexes were assessed and standard echocardiographic examinations were investigated. RESULTS MPI averages in OH, SH, and control groups were 0.53±0.06, 0.51±0.05, and 0.44±0.75 mm, respectively. MPI was increased in the OH and SH groups in comparison to CG (p<0.001, p<0.001, respectively). CONCLUSIONS MPI value was significantly higher in hypothyroid patients in comparison to the control group, showing that regression in global left ventricular functions is an important echocardiographic finding. Future studies are required to determine the effects of this finding on long-term cardiovascular outcomes.

The current study investigated the utility of the Dementia Severity Rating Scale (DSRS) total score to identify individuals at the earliest stage of impairment (ie, mild cognitive impairment/MCI). In addition, the authors sought to investigate how well the measure correlates with an expanded battery of cognitive tests and other measures of functional abilities. Of the 320 participants included in this study, 85 were normal controls, 96 had single-domain or multiple-domain amnestic MCI, and 139 had possible or probable Alzheimer disease (AD). Each participant underwent a thorough cognitive, neurological, and physical examination. Results from this study indicated that the DSRS total scores differed significantly between the 3 groups (P<0.001) and accurately identified 81% of the control group, 60% of the MCI group, and 78% of the AD group in a post hoc discriminant analysis. When combined with a brief cognitive measure (ie, Consortium to Establish a Registry for Alzheimer's Disease Word List 5 min recall test), the DSRS accurately identified 98% of the control group, 76% of the MCI group, and 82% of the AD group. Implications for clinical practice and proposed areas of future research are discussed.

Objective This study was performed to determine the efficacy of selective peripheral nerve resection for treatment of persistent neuropathic pain after total knee arthroplasty (TKA). Methods Patients who underwent TKA in our department from January 2013 to July 2016 and experienced persistent pain around the knee joint after TKA were retrospectively included in the current study. Sixty patients were divided into experimental and control groups according the treatment they received. The treatment effect was evaluated by the Hospital for Special Surgery (HSS) knee score and visual analog scale (VAS) pain score preoperatively and at 1, 2, 3, 6, and 12 months postoperatively. Results The HSS knee scores were higher in both groups after than before the treatment, and HSS knee scores were significantly higher in the experimental group than in the control group. The VAS pain scores were lower in both groups after than before the treatment, and VAS pain scores were significantly lower in the experimental group than in the control group. Conclusions Selective peripheral nerve resection is an effective treatment method for persistent neuropathic pain after TKA.

Research has shown that the use of power mobility devices is safe and beneficial for motor and cognitive development in children with motor disabilities; nevertheless, strong evidence of the benefits for social skill development is limited. This study aimed to examine the effects of combining ride-on car training with an adult-directed, social interaction program in a hospital-based environment on mobility and social functions in young children with motor disabilities. This study used a prospective, nonequivalent pretest-posttest control group design. Twenty-nine young children with motor disabilities, aged between 1 and 3 years, were recruited from local hospitals in Taiwan. The treatment group ( n  = 15) underwent 2-h ride-on car training sessions twice per week for a total of 9 weeks in the hospital environment. The control group ( n  = 14) underwent a 9-week home education program (mean: 200 min/week) focusing on mobility and social skills training. The Chinese version of the Pediatric Evaluation of Disability Inventory, Parenting Stress Index, and Goal Attainment Scaling were administered to all participants before and after the intervention, and at the end of the 9-week follow-up phase. Mobility and social functions significantly improved in both groups after the 9-week intervention, but this improvement was not maintained at the follow-up phase. The treatment group showed significantly better improvement in social function, parenting stress levels, and goal achievement than the control group at posttest. This two-group design study showed the benefits of combining a ride-on car use with a family-centered, structured, social interaction program for positive impacts on mobility, social function, and parenting stress levels. The combination of a modified ride-on car and a social training program has the potential to enhance socialization in young children with motor disabilities. www.ClinicalTrials.gov, identifier NCT02527499.

Is Enterobius vermicularis infestation associated with acute appendicitis?

Enterobius vermicularis might be seen in specimens of patients who underwent surgery due to acute appendicitis. There is still debate as to E. vermicularis infestation causes acute appendicitis. The primary aim of this study is to determine the incidence of E. vermicularis infestation, and the secondary aim is to determine the possible role of E. vermicularis in pathogenesis of appendicitis as well as the adequacy of demographic data and laboratory values in predicting infestation preoperatively. A retrospective investigation was conducted with all patients who underwent appendectomy due to acute appendicitis in a secondary care center. Patients with E. vermicularis were compared with 24 controls that underwent appendectomy during the same time period. Demographic data, preoperative white blood cell (WBC) count, eosinophil counts, and histopathological findings for both groups were analyzed and compared. Enterobius vermicularis was detected in the appendectomy materials in 9 of 1446 patients (0.62 %). Histopathologically, only one of nine patients had acute appendicitis while the others were diagnosed with lymphoid hyperplasia. There were no statistically significant differences between the groups except WBC count. However, the WBC count was significantly (p < 0.05) lower in the group which was detected E. vermicularis. Enterobius vermicularis is rarely associated with the histopathological findings of acute appendicitis. Also eosinophil count and elevation of white blood counts are inadequate for predicting preoperative E. vermicularis.

Enterocutaneous fistula (ECF), enteroatmospheric fistula (EAF), and intra-abdominal sepsis/abscess (IAS) are major challenges for surgeons caring for patients undergoing damage control laparotomy after trauma. To determine independent predictors of ECF, EAF, or IAS in patients undergoing damage control laparotomy after trauma, using the AAST Open Abdomen Registry. The AAST Open Abdomen registry of patients with an open abdomen following damage control laparotomy was used to identify patients who developed ECF, EAF, or IAS and to compare these patients with those without these complications. Univariate analyses were performed to compare these groups of patients. Variables from univariate analyses differing at P < .20 were entered into a stepwise logistic regression model to identify independent risk factors for ECF, EAF, or IAS. Fourteen level I trauma centers. A total of 517 patients with an open abdomen following damage control laparotomy. Complication of ECF, EAF, or IAS. More patients in the ECF/EAF/IAS group than in the group without these complications underwent bowel resection (63 of 111 patients [57%] vs 133 of 406 patients [33%]; P < .001). Within the first 48 hours after surgery, the ECF/EAF/IAS group received more colloids (P < .03) and total fluids (P < .03) than did the group without these complications. The ECF/EAF/IAS group underwent almost twice as many abdominal reexplorations as did the group without these complications (mean [SD] number, 4.1 [4.1] vs 2.2 [3.4]; P < .001). After multivariate analysis, the independent predictors of ECF/EAF/IAS were a large bowel resection (adjusted odds ratio [AOR], 3.56 [95% CI, 1.88-6.76]; P < .001), a total fluid intake at 48 hours of between 5 and 10 L (AOR, 2.11 [95% CI, 1.15-3.88]; P = .02) or more than 10 L (AOR, 1.93 [95% CI, 1.04-3.57]; P = .04), and an increasing number of reexplorations (AOR, 1.14 [95% CI, 1.06-1.21]; P < .001). Large bowel resection, large-volume fluid resuscitation, and an increasing number of abdominal reexplorations were statistically significant predictors of ECF, EAF, or IAS in patients with an open abdomen after damage control laparotomy.

Heredity plays an important role in keratoconus (KC). Consanguineous marriage (CM) can affect the transmission of recessively inherited conditions. We aimed to investigate the role of consanguineous marriage in the development of KC. This study included two groups: the first group comprised 415 patients who underwent surgery for KC for the first time at Khalili University Hospital (Shiraz, Iran), between 2010 and 2014; the second group comprised 415 healthy individuals who served as age- and sex-matched controls for the patient group. All study subjects were from the Fars province in Iran. CM type was evaluated by a standard checklist in both groups. The mean inbreeding coefficient (α) was evaluated and compared between the two groups. The percentage of parental first-cousin marriages was 35.4% in the patient group and 18.3% in the control group. The mean inbreeding coefficient (α) was 0.0291 in the patient group and 0.0135 in the control group. Patients with KC had a significantly higher mean inbreeding coefficient (α) than controls (T = 8, df = 828, P < 0.001). Our study suggests that CM can play a role in the pathogenesis of KC. As this disease is among the most frequent ocular disorders in our country, CM should be considered by health care systems within their screening programs. PMID:29644240

OBJECTIVE Lumbar spinal drainage (LSD) during neurosurgery can have an important effect by facilitating a smooth procedure when needed. However, LSD is quite invasive, and the pathology of brain herniation associated with LSD has become known recently. The objective of this study was to determine the risk of postoperative brain herniation after craniotomy with LSD in neurosurgery overall. METHODS Included were 239 patients who underwent craniotomy with LSD for various types of neurological diseases between January 2007 and December 2016. The authors performed propensity score matching to establish a proper control group taken from among 1424 patients who underwent craniotomy and met the inclusion criteria during the same period. The incidences of postoperative brain herniation between the patients who underwent craniotomy with LSD (group A, n = 239) and the matched patients who underwent craniotomy without LSD (group B, n = 239) were compared. RESULTS Brain herniation was observed in 24 patients in group A and 8 patients in group B (OR 3.21, 95% CI 1.36-8.46, p = 0.005), but the rate of favorable outcomes was higher in group A (OR 1.79, 95% CI 1.18-2.76, p = 0.005). Of the 24 patients, 18 had uncal herniation, 5 had central herniation, and 1 had uncal and subfalcine herniation; 8 patients with other than subarachnoid hemorrhage were included. Significant differences in the rates of deep approach (OR 5.12, 95% CI 1.8-14.5, p = 0.002) and temporal craniotomy (OR 10.2, 95% CI 2.3-44.8, p = 0.002) were found between the 2 subgroups (those with and those without herniation) in group A. In 5 patients, brain herniation proceeded even after external decompression (ED). Cox regression analysis revealed that the risk of brain herniation related to LSD increased with ED (hazard ratio 3.326, 95% CI 1.491-7.422, p < 0.001). Among all 1424 patients, ED resulted in progression or deterioration of brain herniation more frequently in those who underwent LSD than it did in those who did not undergo LSD (OR 9.127, 95% CI 1.82-62.1, p = 0.004). CONCLUSIONS Brain herniation downward to the tentorial hiatus is more likely to occur after craniotomy with LSD than after craniotomy without LSD. Using a deep approach and craniotomy involving the temporal areas are risk factors for brain herniation related to LSD. Additional ED would aggravate brain herniation after LSD. The risk of brain herniation after placement of a lumbar spinal drain during neurosurgery must be considered even when LSD is essential.

Outcomes of tricuspid valve replacement are poor, partly due to right heart remodelling. The research on its underlying mechanisms is hampered by a lack of animal models of tricuspid regurgitation (TR). Our objective was to create a reproducible and clinically compatible TR animal model to study right heart remodelling caused by TR. Fourteen juvenile male Beagle dogs were divided randomly into an intervention group (n = 11) and a sham-operated control group (n = 3). The intervention group underwent thoracotomy and right atrial incision following superior and inferior vena caval occlusion. The anterior leaflet, together with the chordae, of the tricuspid valve was resected in eight dogs ('one leaflet' group), whereas both anterior and posterior leaflets, together with the chordae, were resected in three dogs ('two leaflets' group). The right atrium and chest were then closed. The control group underwent the same procedure, except leaflet resection. One dog from the 'two leaflets' group and one control dog were sacrificed and autopsy was performed at 12 months post-surgery. All dogs survived over the 1-year observation period postoperatively. TR grade IV occurred immediately postoperatively in the 'one leaflet' group, and TR grade IV plus in the 'two leaflets' group. The overall procedure lasted 30-40 min, and the mean time of vena caval occlusion was 87 ± 10 s. Central venous pressure increased from 6 ± 1.2 at baseline to 13 ± 1.7 mmHg (P < 0.01). By 12 months after TR creation, both in the 'one leaflet' group and in the 'two leaflets' group, the right atrial area, tricuspid annular diameter and right ventricular index of myocardial performance increased significantly, right ventricular fractional area change and tricuspid annular plane systolic excursion decreased significantly. Autopsy of the intervention dog revealed oedema, ascites and cirrhosis. Our surgical technique to create a TR animal model was reproducible with high success and survival rates. This animal model would prove suitable to investigate the mechanisms of right heart remodelling. © The Author 2015.

This study aimed to investigate the influence of silicone oil on the retinal nerve fiber layer (RNFL) thickness in patients with primary rhegmatogenous retinal detachment who underwent vitreoretinal surgery. The study included 47 patients (eyes), who underwent a pars plana vitrectomy with the silicone oil tamponade. The control group included unoperated eye of all participants. Spectral-domain optical coherence tomography (SD-OCT) was used for the measurements of peripapilar and macular RNFL thickness. The average peripapillary RNFL thickness was significantly higher in the silicone oil filled eyes during endotamponade and after its removal. The eyes with elevated IOP had less thickening of the RNFL in comparison to the eyes with normal IOP. Central macular thickness and macular volume were decreased in the silicone oil filled eyes in comparison to the control eyes. In conclusion, silicone oil caused peripapilar RNFL thickening in the vitrectomized eyes during endotamponade and after silicone oil removal.

Especially in hidden lesions causing drug-resistant frontal lobe epilepsy (FLE), the localization of the epileptic zone EZ can be a challenge. Magnetoencephalography (MEG) can raise the chances for localization of the (EZ) in combination with electroencephalography (EEG). We investigated the impact of MEG-guided epilepsy surgery with the aid of neuronavigation and intraoperative MR imaging (iopMRI) on seizure outcome of FLE patients. Twenty-eight patients (15 females, 13 males; mean age 31.0±11.1 years) underwent surgery in our department. All patients underwent presurgical MEG monitoring (two-sensor Magnes II or whole head WH3600 MEG system; 4-D Neuroimaging, San Diego, CA, USA). Of those, six patients (group 1) with MRI-negative FLE were operated on before 2002 with intraoperative electrocorticography (ECoG) and invasive EEG mapping only. Eleven patients with MRI-negative FLE (group 2) and eleven with lesional FLE (group 3) underwent surgery using 1.5T-iopMRI and neuronavigation, including intraoperative visualization of the MEG localizations in 22 and functional MR imaging (for motor and speech areas) as well as DTI fiber tracking (for language and pyramidal tracts) in 13 patients. In the first group, complete resection of the defined EZ including the MEG localization according to the latest postoperative MRI was achieved in four out of six patients. Groups two and three had complete removal of the MEG localizations in 20/22 (91%, 10 of 11 each). Intraoperative MRI revealed incomplete resection of the MEG localizations of four patients (12%; two in both groups), leading to successful re-resection. Transient and permanent neurological deficits alike occurred in 7.1%, surgery-associated complications in 11% of all patients. In the first group, excellent seizure outcome (Engel Class IA) was achieved in three (50%), in the second in 7 patients (61%) and third group in 8 patients (64%, two iopMRI-based re-resections). Mean follow-up was 70.3 months (from 12 to 284 months). In our series, MEG-guided resection using neuronavigation and iopMR imaging led to promising seizure control rates. Even in non-lesional FLE, seizure control rates and the probability of complete resection of the MEG localizations was similar to lesional FLE using multimodal navigation.

Surgical isolation of the left atrium was performed for the treatment of chronic atrial fibrillation secondary to valvular disease in 100 patients who underwent valve surgery. From May 1989 to September 1991, 62 patients underwent mitral valve surgery (Group I), 19 underwent mitral valve surgery and DeVega tricuspid annuloplasty (Group II), 15 underwent mitral and aortic surgery (Group III), and 4 patients underwent mitral and aortic surgery and DeVega tricuspid annuloplasty (Group IV). Left atrial isolation was performed prolonging the usual left paraseptal atriotomy towards the left fibrous trigone anteriorly, and the postero-medial commissure posteriorly. The incision was conducted a few millimeters apart from the mitral valve annulus, and cryolesion were placed at the edges to ensure complete electrophysiological isolation of the left atrium. Operative mortality accounted for 3 cases (3%). In 79 patients (81.4%) sinus rhythm recovered and persisted until discharge from the hospital. No differences were found between the groups (Group I: 80.7%; Group II: 68.5%; Group III 86.7%, Group IV 75% - p = N.S.). Three cases of late mortality (3.1%) were registered. long-term results showed persistence of SR in 71% of Group I, 61.2% of Group II, 85.8% of Group III, and 100% of Group IV. The unique risk factor for late recurrency of atrial fibrillation was found to be a duration of preoperative AF longer than 6 months. Due to the high success rate in recovering the sinus rhythm, we suggest left atrial isolation in patients with chronic atrial fibrillation undergoing valvular surgery.

To compare the effects of a vapocoolant spray and an eutectic mixture of local anesthetics (EMLA) cream in reducing pain during needle electromyography examination. Randomized controlled trial. Physical medicine and rehabilitation department of a university hospital. Adults who underwent needle electromyography (N=99) were randomized to 1 of 2 experimental groups or the control group. Two patients dropped out during the study. In the experimental groups, vapocoolant spray or EMLA cream were applied before needle electromyography. In the control group, needle electromyography was performed without pretreatment. Intensity of pain associated with needle electromyography was assessed using a 100-mm visual analog scale (VAS). Patient satisfaction and preference for repeated use were measured using a 5-point Likert scale. VAS score for pain intensity was significantly lower in the spray group (31.9; 95% confidence interval [CI], 22.0-41.7) compared with the control group (52.9; 95% CI, 45.9-60.0; P=.002), whereas there was no significant difference between the EMLA cream group (42.4; 95% CI, 34.2-50.7) and the control group. Patient satisfaction and preference for repeated use were higher in the spray group than the EMLA group. Vapocoolant spray was more effective than EMLA cream in reducing pain during needle electromyography. Copyright © 2013 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

Previous studies have demonstrated that curcumin (CUR) has protective effects against ischemia reperfusion injury to various organs. We aimed to determine whether CUR has favorable effects on tissues and oxidative stress in abdominal aorta ischemia-reperfusion injury. Thirty rats were divided into three groups as sham, control and treatment (CUR) group. Control and CUR groups underwent abdominal aorta ischemia for 60 min followed by a 120 min period of reperfusion. In the CUR group, CUR was given 5 min before reperfusion at a dose of 200 mg/kg via an intraperitoneal route. Total antioxidant capacity (TAC), total oxidative status (TOS), and oxidative stress index (OSI) in blood serum were measured, and lung, renal and heart tissue histopathology were evaluated with light microscopy. TOS and OSI activity in blood samples were statistically decreased in sham and CUR groups compared to the control group (p < 0.001 for TOS and OSI). Renal, lung, heart injury scores of sham and CUR groups were statistically decreased compared to control group (p < 0.001 for all comparisons). Histopathological examination revealed less severe lesions in CUR group than in the control group. CUR administered intraperitoneally was effective in reducing oxidative stress and histopathologic injury in an acute abdominal aorta I/R rat model. Copyright © 2014 Surgical Associates Ltd.

Mesenchymal stem cell-derived extracellular vesicles (EVs) are believed to be cardioprotective in myocardial infarct. The objective of this study was to examine the effects of human mesenchymal cell-derived EV injection on cardiac function, myocardial blood flow, and vessel density in the setting of chronic myocardial ischemia. Twenty-three Yorkshire swine underwent placement of an ameroid constrictor on their left circumflex artery. Two weeks later, the animals were split into 2 groups: the control group (CON; n=7) and the EV myocardial injection group (MVM; n=10). The MVM group underwent myocardial injection of 50 μg of EVs in 2 mL 0.9% saline into the ischemic myocardium. Five weeks later, the pigs underwent a harvest procedure, and the left ventricular myocardium was analyzed. Absolute blood flow and the ischemic/nonischemic myocardial perfusion ratio were increased in the ischemic myocardium in the MVM group compared with the CON group. Pigs in the MVM group had increased capillary and arteriolar density in the ischemic myocardial tissue compared with CON pigs. There was an increase in expression of the phospho-mitogen-activated protein kinase/mitogen-activated protein kinase ratio, the phospho-endothelial nitric oxide synthase/endothelial nitric oxide synthase ratio, and total protein kinase B in the MVM group compared with CON. There was an increase in cardiac output and stroke volume in the MVM group compared with CON. In the setting of chronic myocardial ischemia, myocardial injection of human mesenchymal cell-derived EVs increases blood flow to ischemic myocardial tissue by induction of capillary and arteriolar growth via activation of the protein kinase B/endothelial nitric oxide synthase and mitogen-activated protein kinase signaling pathways resulting in increased cardiac output and stroke volume. © 2018 The Authors.

This is a randomized controlled trial that aimed to evaluate the effect of the Seven-star Needle Stimulation treatment on children with Autistic Spectrum Disorders (ASD). Thirty-two children with ASD were assigned randomly into the treatment and control groups. Children in the treatment group underwent 30 sessions of stimulation over 6 weeks, while children in the control group were on a waiting list and did not receive treatment during this period of time. Intervention consisted of a treatment regime comprising of 30 sessions of Seven-star Needle Stimulation, delivered over 6 weeks. Each session lasted 5 to 10 min, children in the treatment group were stimulated at the front and back sides of their body and the head by using Seven-star Needles. The change in the children's behavior was evaluated using parents' report and neurophysiological changes were measured by quantitative EEG (qEEG). Results showed that the treatment group demonstrated significant improvement in language and social interaction, but not in stereotyped behavior or motor function, compared to the control group. qEEG spectral amplitudes in the treatment, but not in the control group, were also reduced significantly. The results suggested that Seven-star Needle Stimulation might be an effective intervention to improve language and social functioning of children with ASD.

The aim of this study was to compare De Vega semicircular annuloplasty and a new biodegradable ring annuloplasty technique in patients requiring surgical intervention for tricuspid valve disease with concomitant disease of the mitral valve. Between January 2004 and May 2008, 129 consecutive patients underwent annuloplasty procedures to correct tricuspid valve regurgitation during a concomitant mitral valve operation requiring replacement. Additionally, 24 patients underwent aortic valve replacement (AVR), 11 underwent coronary artery bypass grafting (CABG), 5 underwent AVR plus CABG, 3 underwent mitral valve replacement plus atrial septal defect (ASD) closure, and 2 underwent ASD closure. The patients in this study were assigned to 2 groups: Kalangos ring annuloplasty was performed in 67 patients (group 1), and De Vega semicircular annuloplasty was performed in the remaining 62 patients (group 2). Both tricuspid valve repair techniques produced a low rate of complications; however, the number of patients who developed residual tricuspid regurgitation was significantly lower in group 1. The biodegradable ring annuloplasty technique may be used easily and safely in moderate and severe cases of tricuspid regurgitation; however, larger clinical series are necessary to confirm our promising results.

This study examines the effectiveness of physical exercise, during a prepathology state, on locomotor balance compensation after subsequent unilateral labyrinthectomy in squirrel monkeys. An experimental group underwent 3 hr. of daily running exercise on a treadmill for 3 mo. prior to the surgery, whereas a control group was not exercised. Postoperatively, the locomotor balance function of both groups was tested for 3 mo. There was no significant difference in gait deviation counts in the acute phase of compensation. However, in the chronic compensation maintenance phase, the number of gait deviation counts was fewer in the exercise group, which showed significantly better performance stability.

Submental fat accumulation and skin laxity is a frequent concern of cosmetic patients. The aim of this randomized prospective controlled clinical trial was to compare the efficacy and safety of laser-assisted lipolysis and liposuction in the submental rejuvenation. Thirty-six female adults were enrolled in this clinical trial and were categorized into two groups: group 1 underwent 980-nm diode laser with the power of 6-8 W and group 2 underwent traditional liposuction. Patients were evaluated with ultrasonography 2 weeks and 2 months after the procedures. Ultrasonographic evaluation reported the significant reduction of fat thickness in each group compared with the baseline (p value < 0.001). At the 2 weeks and 2 months follow-up visit, fat thickness reduction was significantly higher in the lipolysis group (p value < 0.05). Overall patients' satisfaction in lipolysis group was higher than liposuction with 11 (61%) of lipolysis patients being very satisfied in contrast to 10 (55.5%) of liposuction patients reporting "dissatisfied or neutral" results. Laser-assisted lipolysis using 980-nm diode is approved to be safe and effective for skin tightening and rejuvenation of the submental area and seems to be a better option than traditional techniques for treatment of this cosmetic problem.

Cryotherapy is a physiotherapy method used to treat back pain in older persons. This study aims to evaluate the changes in the rheological parameters of blood in older women with spondyloarthrosis, who underwent whole-body cryotherapy. The experimental group comprised 69 older women with lumbar spondyloarthrosis, aged between 65 and 70 years. Due to the methodology of the procedure, the experimental group was randomly divided into three groups. Each group underwent two weeks of different types of physiotherapy: only whole-body cryotherapy (22 women); only kinesitherapy (23 women); and both cryotherapy and kinesitherapy (24 women). The control group comprised 25 women who did not undergo any form of therapy. The evaluation of the rheological properties of the blood encompassed measurements of the plasma viscosity, the erythrocyte elongation and aggregation indices, and the level of fibrinogen. The conducted rheological tests revealed a significant decrease in the erythrocyte elasticity and aggregation indices only in the group of women who had undergone both whole-body cryotherapy and kinesitherapy. Applying whole-body cryotherapy to older women with spondyloarthrosis decreases the elasticity of erythrocytes and, despite favourable changes in the aggregation parameters, problems with perfusion may still appear. For this reason, the benefit of using whole-body cryotherapy in these persons is debatable.

Hu, Yong, E-mail: hu.yong@zs-hospital.sh.cn; Zhou,

Purpose: While abdominal compression (AC) can be used to reduce respiratory liver motion in patients receiving helical tomotherapy for hepatocellular carcinoma, the nature and extent of this effect is not well described. The purpose of this study was to evaluate the changes in magnitude of three-dimensional liver motion with abdominal compression using four-dimensional (4D) computed tomography (CT) images of several plate positions. Methods: From January 2012 to October 2015, 72 patients with intrahepatic carcinoma and divided into four groups underwent 4D-CT scans to assess respiratory liver motion. Of the 72 patients, 19 underwent abdominal compression of the cephalic area betweenmore » the subxiphoid and umbilicus (group A), 16 underwent abdominal compression of the caudal region between the subxiphoid area and the umbilicus (group B), 11 patients underwent abdominal compression of the caudal umbilicus (group C), and 26 patients remained free breathing (group D). 4D-CT images were sorted into ten-image series, according to the respiratory phase from the end inspiration to the end expiration, and then transferred to treatment planning software. All liver contours were drawn by a single physician and confirmed by a second physician. Liver relative coordinates were automatically generated to calculate the liver respiratory motion in different axial directions to compile the 10 ten contours into a single composite image. Differences in respiratory liver motion were assessed with a one-way analysis of variance test of significance. Results: The average respiratory liver motion in the Y axial direction was 4.53 ± 1.16, 7.56 ± 1.30, 9.95 ± 2.32, and 9.53 ± 2.62 mm in groups A, B, C, and D, respectively, with a significant change among the four groups (p < 0.001). Abdominal compression was most effective in group A (compression plate on the subxiphoid area), with liver displacement being 2.53 ± 0.93, 4.53 ± 1.16, and 2.14 ± 0.92 mm on the X-, Y-, and Z-axes, respectively. There was no significant difference in respiratory liver motion between group C (displacement: 3.23 ± 1.47, 9.95 ± 2.32, and 2.92 ± 1.10 mm on the X-, Y-, and Z-axes, respectively) and group D (displacement: 3.35 ± 1.55, 9.53 ± 2.62, and 3.35 ± 1.73 mm on the X-, Y-, and Z-axes, respectively). Abdominal compression was least effective in group C (compression on caudal umbilicus), with liver motion in this group similar to that of free-breathing patients (group D). Conclusions: 4D-CT scans revealed significant liver motion control via abdominal compression of the subxiphoid area; however, this control of liver motion was not observed with compression of the caudal umbilicus. The authors, therefore, recommend compression of the subxiphoid area in patients undergoing external radiotherapy for intrahepatic carcinoma.« less

The aim of the current study was to observe the effects of Twenty-four Move Shadow Boxing combined with psychosomatic relaxation on depression and anxiety in patients with Type-2 Diabetes. One hundred and twenty (120) patients with Type-2 Diabetes and depressive/anxious symptoms were divided into intervention group (60 cases) and control group (60 cases) according to the minimum distribution principle of unbalanced indicators. Twenty-four Move Shadow Boxing group used this intervention combined with psychosomatic relaxation. Control group underwent conventional treatment. All the patients in the two groups completed the Self-rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) before and after treatment. Among the 52 people included in the statistical analysis, the recovery rate was 13.3%. The differences between depression and anxiety scores in the intervention group before and after treatment were statistically significant (P<0.001), whereas these differences were non-significant in the control group (P=0.123). After the treatment, the glycated hemoglobin reduction in the intervention group was greater than that of the control group (t=2.438, P=0.016). The combination of Twenty-four Move Shadow Boxing and psychosomatic relaxation has a beneficial auxiliary therapeutic effect on depression and anxiety accompanying Type-2 Diabetes.

Anterior cervical discectomy and fusion (ACDF) is a well-accepted treatment option for patients with cervical spine disease. Three- and four-level discectomies are known to be associated with a higher complication rate and lower fusion rate than single-level surgery. This study was performed to evaluate and compare zero-profile fixation and stand-alone PEEK cages for three- and four-level ACDF. Two cohorts of patients who underwent ACDF for the treatment of three- and four-level disease were compared. Thirty-three patients underwent implantation of zero-profile devices that included titanium screw fixation (Group A). Thirty-five patients underwent implantation of stand-alone PEEK cages without any form of screw fixation (Group B). In Group A, twenty-seven patients underwent a three-level and six patients a four-level ACDF, with a total of 105 levels. In Group B, thirty patients underwent a three-level and five patients underwent a four-level ACDF, with a total number of 110 levels. In Group A, the mean preoperative visual analog scale score (VAS) for arm pain was 6.4 (range 3-8), and the mean postoperative VAS for arm pain decreased to 2.5 (range 1-7). In group B, the mean preoperative VAS of arm pain was 7.1 (range 3-10), and the mean postoperative VAS of arm pain decreased to 2 (range 0-4). In Group A, four patients (12%) developed dysphagia, and in Group B, three patients (9%) developed dysphagia.  Conclusions: This study found zero-profile instrumentation and PEEK cages to be both safe and effective for patients who underwent three- and four-level ACDF, comparable to reported series using plate devices. Rates of dysphagia for the cohort were much lower than reports using plate devices. Zero-profile segmental fixation devices and PEEK cages may be considered as viable alternatives over plate fixation for patients requiring multi-level anterior cervical fusion surgery.

In this study, we investigated the effects of dual-hemisphere transcranial direct current stimulation (dual-tDCS) of both the affected (anodal tDCS) and non-affected (cathodal tDCS) primary motor cortex, combined with peripheral neuromuscular electrical stimulation (PNMES), on the effectiveness of constraint-induced movement therapy (CIMT) as a neurorehabilitation intervention in chronic stroke. We conducted a randomized controlled trial of feasibility, with a single blind assessor, with patients recruited from three outpatient clinics. Twenty chronic stroke patients were randomly allocated to the control group, receiving conventional CIMT, or the intervention group receiving dual-tDCS combined with PNMES before CIMT. Patients in the treatment group first underwent a 20-min period of dual-tDCS, followed immediately by PNMES, and subsequent CIMT for 2 h. Patients in the control group only received CIMT (with no pretreatment stimulation). All patients underwent two CIMT sessions, one in the morning and one in the afternoon, each lasting 2 h, for a total of 4 h of CIMT per day. Upper extremity function was assessed using the Fugl-Meyer Assessment (primary outcome), as well as the amount of use (AOU) and quality of movement (QOM) scores, obtained via the Motor Activity Log (secondary outcome). Nineteen patients completed the study, with one patient withdrawing after allocation. Compared to the control group, the treatment improvement in upper extremity function and AOU was significantly greater in the treatment than control group (change in upper extremity score, 9.20 ± 4.64 versus 4.56 ± 2.60, respectively, P  < 0.01, η 2  = 0.43; change in AOU score, 1.10 ± 0.65 versus 0.62 ± 0.85, respectively, P  = 0.02, η 2  = 0.52). There was no significant effect of the intervention on the QOM between the intervention and control groups (change in QOM score, 1.00 ± 0.62 versus 0.71 ± 0.72, respectively, P  = 0.07, η 2  = 0.43; treatment versus control). Our findings suggest a novel pretreatment stimulation strategy based on dual-tDCS and PNMES may enhance the therapeutic benefit of CIMT.

We aimed to investigate the relationship between peripheral vertigo and inflammation by using the neutrophil-to-lymphocyte ratio (NLR) as an inflammatory marker. We recruited 103 patients with peripheral vertigo (71 women, 32 men; mean age, 39.8 ± 14.7 years) who presented to the Otolaryngology Department of Dumlupinar University Hospital. Vertigo patients with systemic diseases, neurological disorders, malignancy or any inflammatory disease that could alter the NLR were excluded from the study. We also enrolled 103 age- and sex-matched healthy subjects (controls; 82 women, 21 men; mean age, 36.7 ± 13.5 years) who underwent routine checkups in our hospital. The vertigo patients underwent full otolaryngologic and neurologic examinations and audiometric tests to rule out any other pathology causing the peripheral vertigo. NLR was calculated in all subjects and was compared between the patient and control groups. There were no significant differences between the study and control groups in terms of lipid profiles, liver-function tests, white blood cell (WBC) count, hemoglobin level, mean platelet volume, and vitamin B12 and folate levels. The mean NLR was significantly higher in the patients than in the controls (P<0.05). In conclusion, this study, which was the first to investigate the relationship between the NLR and peripheral vertigo, found that the NLR is significantly higher among peripheral vertigo patients than among healthy controls. This result suggests that the NLR is a novel potential marker of stress in peripheral vertigo patients. Copyright © 2014 Elsevier Inc. All rights reserved.

Nursing project management is widely used in different aspects of the society. However, whether the nursing project management can control the infections in the operation room (OR) is rarely reported. We evaluated the outcomes of surgical patients after implementing a nursing project management program to provide new scientific ways to manage the OR infections. Overall, 382 patients, who underwent surgical treatment in Qilu Hospital of Shandong University, Shandong, China from May 2015 to January 2016, were enrolled as observation group. Besides, 347 cases were selected as control group. Patients in the observation group were treated with the nursing project management plan, while patients in the control group were treated with the routine operation-room nursing measures. The infection control rates in the OR, and the patient satisfaction with the nursing team postoperatively were both compared between the two groups of patients. The OR air, the surgical and personnel's hands surfaces were sampled for colony forming units, and all were found to be significantly of better quality (indicated by less colony forming units) in the observation group (P<0.001). In addition, there were 3 cases (0.79%) of post-operation infections in the observation group, while 12 cases (3.46%) occurred in the control group. The overall infection rate of the observation group was significantly lower than that of the control group (P = 0.011); and the satisfaction of patients with the nursing team in the observation group was significantly higher than that of the patients in the control group ( P = 0.001). It is worth popularizing and applying a good nursing project management plan for surgical patients in hospitals.

An increasing number of patients presenting for urgent coronary surgery have been exposed to clopidogrel, which constitutes a risk of bleeding and related events. Based on the wide variability in clopidogrel response and platelet function recovery after cessation, we evaluated the role of point-of-care platelet function testing to define the optimal time for off-pump coronary artery bypass graft (CABG) surgery in a case-control study. Three equally matched groups (300 patients in total) undergoing isolated off-pump CABG for acute coronary syndrome were compared. Group A were treated with clopidogrel and prospectively underwent a strategy guided by platelet function testing. Outcomes were compared with 2 propensity score matched groups: group B underwent CABG after the currently recommended 5 days without clopidogrel; group C were never exposed to clopidogrel. Patients in group A had reduced postoperative bleeding compared with those in group B (523±202 mL vs 851±605 mL; P<.001) and a lower number of units packed red blood cells (PRBCs) transfused during the postoperative hospital stay (1.2±1.6 units vs 1.9±1.8 units; P=.004). Postoperative bleeding and the number of units of PRBCs transfused were similar in group A and group C. There was no difference in blood-derived products and platelet consumption, mortality, or the need for reoperation among the groups. Patients in group A waited 3.6±1.7 days for surgery. The strategy used for group A saved 280 days of hospital stay in total. The strategy guided by platelet function testing for off-pump CABG offers improved guidance for optimal timing of CABG in patients treated with clopidogrel. This strategy significantly reduces postoperative bleeding and blood consumption, and has a shorter waiting time for surgery than current clinical practice.

To identify the role of bilateral internal iliac artery (IIA) ligation on reducing blood loss in abnormally invasive placenta (AIP) undergoing caesarean hysterectomy. In this parallel-randomized control trial, 57 pregnant females with ultrasound features suggestive of AIP were enrolled. They were randomized into two groups; IIA group (n = 29 cases) performed bilateral IIA ligation followed by caesarean hysterectomies, while Control group (n = 28 cases) underwent caesarean hysterectomy only. The main outcome was the difference in the estimated intraoperative blood loss between the two groups. There was no significant difference between the two groups regarding the intraoperative estimated blood loss (1632 ± 804 versus 1698 ± 1251, p value .83). The operative procedure duration (minutes) (223 ± 66 versus 171 ± 41.4, p value .001) varied significantly between the two groups. Bilateral internal iliac artery ligation, in cases of AIP undergoing caesarean hysterectomy, is not recommended for routine practice to minimize blood loss intraoperatively.

To evaluate the effect of transabdominal amnioinfusion on prolongation of pregnancy, and maternal and neonatal outcomes in preterm premature rupture of membranes (pPROM). We conducted a prospective randomized controlled study of women with pPROM during singleton live pregnancy-between 26 and 33+6weeks-whose amniotic fluid index (AFI) was less than the 5th percentile. The study group underwent transabdominal amnioinfusion at admission and then weekly if their AFI fell below the 5th percentile again. The control group received expectant management. The difference in the mean interval from pPROM to delivery between the groups was not statistically significant. Neonatal and maternal outcomes were significantly improved in the study group compared with the control group (fetal distress [10% vs 37%]; early neonatal sepsis [17% vs 63%]; neonatal mortality [17% vs 63%]; spontaneous delivery [83% vs 53%]; and postpartum sepsis [7% vs 33%]). Transabdominal amnioinfusion reduced fetal distress, early neonatal sepsis, and neonatal mortality. In the study group, more participants delivered spontaneously and there were fewer cases of postpartum sepsis, although the pPROM-delivery interval was not increased.

Background Visual hallucinations and visuoperceptual deficits are common in dementia with Lewy bodies, suggesting that cortical visual function may be abnormal. Aims To investigate: (1) cortical visual function using functional magnetic resonance imaging (fMRI); and (2) the nature and severity of perfusion deficits in visual areas using arterial spin labelling (ASL)-MRI. Method In total, 17 participants with dementia with Lewy bodies (DLB group) and 19 similarly aged controls were presented with simple visual stimuli (checkerboard, moving dots, and objects) during fMRI and subsequently underwent ASL-MRI (DLB group n = 15, control group n = 19). Results Functional activations were evident in visual areas in both the DLB and control groups in response to checkerboard and objects stimuli but reduced visual area V5/MT (middle temporal) activation occurred in the DLB group in response to motion stimuli. Posterior cortical perfusion deficits occurred in the DLB group, particularly in higher visual areas. Conclusions Higher visual areas, particularly occipito-parietal, appear abnormal in dementia with Lewy bodies, while there is a preservation of function in lower visual areas (V1 and V2/3).

To investigate the clinical value of T shape approach in the treatment of proximal tibial fractures. One handrend and thirteen patients of proximal tibial fractures were randomly divided into two groups. Group A: 62 cases underwent the traditional exposure approach. According to Schatzker classification,the cases of II to VI type was 25, 10, 16, 6, 5 respectively. Group B:51 cases underwent T shape approach ahead of knee joint, the cases of II to VI type was 21, 8, 13, 5, 4 respectively. All data were analyzed by SPSS 10.0 to compare operation time, blood loss, duration of hospitalization, healing time, the time of osseous union and complications after operation. Sixty patients in group A and 50 patients in group B were followed-up from 12 to 24 months. (1) Operation time:group B was longer than A (P < 0.01). (2) Mean blood loss and duration of hospitalization was the same. (3) Clinical healing time:group B was shorter. (4) Mean time of osseous union: 48 group B was shorter. Function of knee: group B was better than group A. (Complication: group B was less than group A. As compared with traditional exposure approach, T shape approach of knee joint had advantages of small scar, fewer complications, faster union of fracture and earlier recovery of joint function. The approach is valuable for the treatment of proximal tibial fractures.

The aim of this study was to evaluate the effectiveness of repetitive locomotor training with an electromechanical gait trainer in children with cerebral palsy. In this randomized controlled trial, 18 ambulatory children with diplegic or tetraplegic cerebral palsy were randomly assigned to an experimental group or a control group. The experimental group received 30 mins of repetitive locomotor training with an applied technology (Gait Trainer GT I) plus 10 mins of passive joint mobilization and stretching exercises. The control group received 40 mins of conventional physiotherapy. Each subject underwent a total of 10 treatment sessions over a 2-wk period. Performance on the 10-m walk test, 6-min walk test, WeeFIM scale, and gait analysis was evaluated by a blinded rater before and after treatment and at 1-mo follow-up. The experimental group showed significant posttreatment improvement on the 10-m walk test, 6-min walk test, hip kinematics, gait speed, and step length, all of which were maintained at the 1-mo follow-up assessment. No significant changes in performance parameters were observed in the control group. Repetitive locomotor training with an electromechanical gait trainer may improve gait velocity, endurance, spatiotemporal, and kinematic gait parameters in patients with cerebral palsy.

The aim was to determine in what extent physical activity influences postural control when visual, vestibular, and/or proprioceptive systems are disrupted. Two groups of healthy older women: an active group (74.0 ± 3.8 years) who practiced physical activities and a sedentary group (74.7 ± 6.3 years) who did not, underwent 12 postural conditions consisted in altering information emanating from sensory systems by means of sensory manipulations (i.e., eyes closed, cervical collar, tendon vibration, electromyostimulation, galvanic vestibular stimulation, foam surface). The center of foot pressure velocity was recorded on a force platform. Results indicate that the sensory manipulations altered postural control. The sedentary group was more disturbed than the active group by the use of tendon vibration. There was no clear difference between the two groups in the other conditions. This study suggests that the practice of physical activities is beneficial as a means of limiting the effects of tendon vibration on postural control through a better use of the not manipulated sensory systems and/or a more efficient reweighting to proprioceptive information from regions unaffected by the tendon vibration. © 2014 John Wiley & Sons A/S.

Intraabdominal adhesions remain a significant cause of morbidity and mortality. Moreover, intraabdominal adhesions can develop in more than 50% of abdominal operations. We compared the anti-adhesive effects of two different agents on postoperative adhesion formation in a cecal abrasion model. Experimental animal study. Forty Wistar albino type female rats were anesthetized and underwent laparotomy. Study groups comprised Sham, Control, Mitomycin-C, 4% Icodextrin, and Mitomycin-C +4% Icodextrin groups. Macroscopic and histopathological evaluations of adhesions were performed. The frequencies of moderate and severe adhesions were significantly higher in the control group than the other groups. The mitomycin-C and Mitomycin-C +4% Icodextrin groups were associated with significantly lower adhesion scores compared to the control group and 4% Icodextrin group scores (p=0.002 and p=0.008, respectively). The adhesion scores of the Mitomycin-C group were also significantly lower than those of the 4% Icodextrin group (p=0.008). Despite its potential for bone marrow toxicity, Mitomycin-C seems to effectively prevent adhesions. Further studies that prove an acceptable safety profile relating to this promising anti-adhesive agent are required before moving into clinical trials.

Cognitive impairment occurs frequently in post-stroke patients. This study aimed to determine the effects of a virtual reality training (VRT) with BTs-Nirvana (BTsN) on the recovery of cognitive functions in stroke patients, using the Interactive-Semi-Immersive Program (I-SIP). We enrolled 12 subjects (randomly divided into two groups: experimental group (EG); and control group (CG)), who attended the Laboratory of Robotic and Cognitive Rehabilitation of IRCCS Neurolesi of Messina from January to June 2016. The EG underwent a VRT with BTsN, whereas CG received a standard cognitive treatment. Both the groups underwent the same conventional physiotherapy program. Each treatment session lasted 45 minutes and was repeated three times a week for 8 weeks. All the patients were evaluated by a specific clinical-psychometric battery before (T0), immediately (T1), and one month (T2) after the end of the training. At T1, the EG presented a greater improvement in the trunk control test (p = 0.03), the Montreal Cognitive Assessment (p = 0.01), the selective attention assessment scores (p = 0.01), the verbal memory (p = 0.03), and the visuospatial and constructive abilities (p = 0.01), as compared to CG. Moreover, such amelioration persisted at T2 only in the EG. According to these preliminary data, VRT with I-SIP can be considered a useful complementary treatment to potentiate functional recovery, with regard to attention, visual-spatial deficits, and motor function in patients affected by stroke.

Post-operative pneumonia is a frequent and possibly fatal complication of esophagectomy and is likely caused by aspiration of oropharyngeal fluid that contains pathogenic micro-organisms. We conducted a multi-center retrospective study to investigate the preventive effect of oral health care on post-operative pneumonia among patients with esophageal cancer who underwent esophagectomy. A total of 280 patients underwent esophagectomy at three university hospitals. These patients were divided retrospectively into those who received pre-operative oral care from dentists and dental hygienists (oral care group; n = 173) and those who did not receive such care (control group; n = 107). We evaluated the correlations between the occurrence of post-operative pneumonia and 18 predictive variables (patient factors, tumor factors, treatment factors, and pre-operative oral care) using the χ(2) test and logistic regression analysis. The differences of mean hospital days and mortality rate in both groups were analyzed by the Student t-test. Age, post-operative dysphagia, and absence of pre-operative oral care were correlated significantly with post-operative pneumonia in the univariable analysis. Multivariable analysis revealed that diabetes mellitus, post-operative dysphagia, and the absence of pre-operative oral care were independent risk factors for post-operative pneumonia. The mean hospital stay and mortality rate did not differ between the oral care and control groups. Pre-operative oral care may be an effective and easy method to prevent post-operative pneumonia in patients who are undergoing esophagectomy.

To evaluate the influence of aerobic exercise on oxidative stress in mice. The study included twenty female mice Mus musculus-Swiss divided into two groups: sedentary control (GA) and exercise (GB), each containing ten animals. All animals underwent an adaptation period of seven days isolated in individual boxes. After this period, the animals in the exercise group (GB) were trained in angled running wheel with circumference of 25 cm assembled on an articulated axle during five minutes for three consecutive days. On the fourth day, they underwent an exercise program of one session lasting 45 minutes. The evaluation of oxidative stress was performed by determining the levels of malondialhyde derived of lipid peroxidation by the TBA method. The samples were read in a spectrophotometer at 535 nm. No significant difference was observed in the intergroup comparison of MDA levels in the tissues evaluated. A significant difference was observed in the intragroup comparison of MDA levels in the control group (p = 0.0201).The Tukeys' post hoc test indicated significantly lower values of MDA in the smooth muscle in relation to plasma. In the analysis of variance in the exercise group, a significant difference between tissues (p = 0.0009), with significantly lower values in the smooth muscle in relation to plasma (p<0.001) and higher in striated muscle in relation to smooth muscle (p<0.05) was observed. There was no change in the analysis of oxidative stress in mice which were undergone a single session of aerobic exercise.

Traditionally, hernia sac ligation during inguinal hernia repair is considered mandatory to prevent postoperative development of hernia. However, ligation may induce postoperative pain. The aim of this study was to evaluate the outcomes of hernia sac ligation after inguinal hernia repair. We conducted a systematic review and meta-analysis of randomized controlled trials to investigate the outcomes of hernia sac ligation for open or laparoscopic inguinal hernia repair. Incidence of hernia recurrence was assessed following the surgery. The secondary outcomes included pain scores and postoperative complications. Five trials were selected and their results were summarized. These 5 trials were published between 1984 and 2014, and the sample sizes ranged from 50 to 467 patients. Four trials had recruited patients with inguinal hernia who underwent open repair, and one study enrolled patients who underwent laparoscopic procedures. We observed no difference in the incidence of hernia recurrence and postoperative complications between the sac ligation and nonligation groups. Postoperatively, the intensity of pain was significantly higher in the ligation group than in the nonligation group at Day 7 (Weight mean difference 1.46; 95% confident interval: 0.98-1.95). Hernia sac ligation was associated with higher postoperative pain, and did not show any benefit over sac nonligation regarding the incidence of recurrence and postoperative complications in patients undergoing open tension-free mesh repair or laparoscopic procedures.

Improving both systolic and diastolic function may be the most important factor in treating heart failure. In this study, we hypothesized that cell-sheet transplantation could improve these function in the damaged heart. We generated a dilated cardiomyopathy model in beagles by continuous ventricle pacing at 240 beats per minute. After 4 weeks, the beagles underwent skeletal myoblast cell sheet transplantation (SMCST) or a sham operation, and rapid ventricle pacing continued for an additional 4 weeks. Six of the e8 beagles treated by SMCST were still alive 4 weeks after the procedure. We evaluated SMCST's cardiotherapeutic effects by comparing beagles treated by SMCST with beagles that underwent a sham operation (control, n = 5). Diastolic function, as well as systolic function improved significantly in the SMCST group as compared with the sham group (control vs SMCST group, median [interquartile range]: E/E', 16 [0.9] vs 11 [1.0]; P < 0.001; tau, 47 [6.0] vs 36 [4.4] ms: P = 0.005. Ejection fraction, 22 (6.0) versus 46 (7.5) %, P < 0.001; end-systolic elastance, 2.5 (0.4) versus 8.2 (3.5) mm Hg/ml, P = 0.001). Histological examination revealed that the volume of collagen I and the collagen I/III ratio in the myocardium were significantly higher in the control than that in the SMCST group (collagen I, 6.0 [0.8] vs 2.6 [1.3]; P = 0.006; collagen I/III ratio, 4.8 [1.7] vs 1.2 [0.4]; P = 0.010). The potential of SMCST to ameliorate both systolic and diastolic performance was proven. The SMCST may be an alternative therapy of conventional medical treatment in the dilated cardiomyopathy heart.

Background Sympathetic activity involves the pathogenesis of atrial fibrillation (AF). Renal sympathetic denervation (RSD) decreases sympathetic renal afferent nerve activity, leading to decreased central sympathetic drive. The aim of this study was to identify the effects of RSD on AF inducibility induced by hyper-sympathetic activity in a canine model. Methods To establish a hyper-sympathetic tone canine model of AF, sixteen dogs were subjected to stimulation of left stellate ganglion (LSG) and rapid atrial pacing (RAP) for 3 hours. Then animals in the RSD group (n = 8) underwent radiofrequency ablation of the renal sympathetic nerve. The control group (n = 8) underwent the same procedure except for ablation. AF inducibility, effective refractory period (ERP), ERP dispersion, heart rate variability and plasma norepinephrine levels were measured at baseline, after stimulation and after ablation. Results LSG stimulation combined RAP significantly induced higher AF induction rate, shorter ERP, larger ERP dispersion at all sites examined and higher plasma norepinephrine levels (P<0.05 in all values), compared to baseline. The increased AF induction rate, shortened ERP, increased ERP dispersion and elevated plasma norepinephrine levels can be almost reversed by RSD, compared to the control group (P<0.05). LSG stimulation combined RAP markedly shortened RR-interval and standard deviation of all RR-intervals (SDNN), Low-frequency (LF), high-frequency (HF) and LF/HF ratio (P<0.05). These changes can be reversed by RSD, compared to the control group (P<0.05). Conclusions RSD significantly reduced AF inducibility and reversed the atrial electrophysiological changes induced by hyper-sympathetic activity. PMID:24223140

Onyx, an ethylene-vinyl alcohol copolymer mixed in a dimethyl sulfoxide solvent, is currently one of the most widely used liquid materials for embolization of intracranial arteriovenous malformations (AVMs). The goal of this study was to define the risks and benefits of stereotactic radiosurgery (SRS) for patients who have previously undergone partial AVM embolization with Onyx. Among a consecutive series of 199 patients who underwent SRS between January 2007 and December 2012 at the University of Virginia, 25 patients had Onyx embolization prior to SRS (the embolization group). To analyze the obliteration rates and complications, 50 patients who underwent SRS without prior embolization (the no-embolization group) were matched by propensity score method. The matched variables included age, sex, nidus volume before SRS, margin dose, Spetzler-Martin grade, Virginia Radiosurgery AVM Scale score, and median imaging follow-up period. After Onyx embolization, 18 AVMs were reduced in size. Total obliteration was achieved in 6 cases (24%) at a median of 27.5 months after SRS. In the no-embolization group, total obliteration was achieved in 20 patients (40%) at a median of 22.4 months after SRS. Kaplan-Meier analysis demonstrated obliteration rates of 17.7% and 34.1% in the embolization group at 2 and 4 years, respectively. In the no-embolization group, the corresponding obliteration rates were 27.0% and 55.9%. The between-groups difference in obliteration rates after SRS did not achieve statistical significance. The difference in complications, including adverse radiation effects, hemorrhage episodes, seizure control, and patient mortality also did not reach statistical significance. Onyx embolization can effectively reduce the size of many AVMs. This case-control study did not show any statistically significant difference in the rates of embolization or complications after SRS in patients who had previously undergone Onyx embolization and those who had not.

To compare the efficacy, safety, and cost-effectiveness of a three-catheter approach with a conventional five-catheter approach for the mapping and ablation of supraventricular tachycardia in pediatric patients with Wolff-Parkinson-White Syndrome (WPW) and concealed accessory pathways (APs). A retrospective review from 2008 to 2012 of patients less than 21 years with WPW who underwent a three-catheter radiofrequency (RF) ablation of a left-sided AP (ablation, right ventricular [RV] apical, and coronary sinus [CS] decapolar catheters) was performed. The three-catheter group was compared to a control group who underwent a standard five-catheter (ablation, RV apical, CS decapolar, His catheter, and right atrial catheter) ablation for the treatment of left-sided WPW or concealed AP. Demographics, ablation outcomes, and costs were compared between groups. Twenty-eight patients met inclusion criteria with 28 control patients. The groups did not differ in gender, age, weight, or body surface area. Locations of the AP on the mitral annulus were similar between the groups. All patients were ablated via transseptal approach. Note that 28 of 28 in the three-catheter group (100%) and 27 of 28 (96%) controls were acutely successfully ablated (P = 0.31). No complications were encountered. There was no difference in procedural time, time to loss of AP conduction, or number of RF applications. Use of the three-catheter technique resulted in a total savings of $2,465/case, which includes the $680 savings from using fewer catheters as well as the savings from a shortened procedure time. Ablation in patients with WPW and a left-sided AP can be performed using three catheters with similar efficacy and safety while offering significant cost savings compared to a conventional five-catheter approach. © 2015 Wiley Periodicals, Inc.

Multicenter case-control study. To characterize the pathogenesis of idiopathic spinal epidural lipomatosis (SEL). SEL is often associated with the history of steroid use or endocrine disorders; however, the pathogenesis of idiopathic SEL remains poorly understood. Sixteen patients who underwent lumbar decompression surgery due to severe idiopathic SEL were included in the study (L group, 15 men and 1 woman; mean age, 71.5 yrs). Fifteen patients without SEL, who underwent decompression surgery for lumbar canal stenosis, were selected as controls (C group, 14 men and 1 woman; mean age, 70.3 yrs). The following parameters were analyzed in these two groups: body mass index (BMI), medical history, histology, the size of adipocytes in the epidural fat (EF) tissues, and the expression level of the transcripts for adiponectin, leptin, tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, and IL-8. The mean BMI of the L group was significantly higher than that of the C group (29.1 vs. 25.2 kg/m, P = 0.006), and there was a significant correlation between BMI and the width of EF in both groups. The average adipocyte size in the EF was significantly larger in the L group than in the C group (2846.8 vs. 1699.0 μm, P = 0.017). Furthermore, the expression levels of the transcripts for TNF-α and IL-1β in the L group were significantly higher than those in the C group [2.59-fold increase (P = 0.023) and 2.60-fold increase (P = 0.015), respectively]. Our data suggest that the pathogenesis of idiopathic SEL is associated with obesity. In addition, the increased expression of two major inflammatory cytokines in the EF in the L group may indicate that SEL is causally related to chronic inflammation. 3.

Previous studies have demonstrated that thymoquinone has protective effects against ischemia reperfusion injury to various organs like lungs, kidneys and liver in different experimental models. We aimed to determine whether thymoquinone has favorable effects on lung, renal, heart tissues and oxidative stress in abdominal aorta ischemia-reperfusion injury. Thirty rats were divided into three groups as sham (n=10), control (n=10) and thymoquinone (TQ) treatment group (n=10). Control and TQ-treatment groups underwent abdominal aorta ischemia for 45 minutes followed by a 120-min period of reperfusion. In the TQ-treatment group, thymoquinone was given 5 minutes. before reperfusion at a dose of 20 mg/kg via an intraperitoneal route. Total antioxidant capacity, total oxidative status (TOS), and oxidative stress index (OSI) in blood serum were measured and lung, kidney, and heart tissue histopathology were evaluated with light microscopy. Total oxidative status and oxidative stress index activity in blood samples were statistically higher in the control group compared to the sham and TQ-treatment groups (P<0.001 for TOS and OSI). Control group injury scores were statistically higher compared to sham and TQ-treatment groups (P<0.001 for all comparisons). Thymoquinone administered intraperitoneally was effective in reducing oxidative stress and histopathologic injury in an acute abdominal aorta ischemia-reperfusion rat model.

Damage control surgery (DCS) is an important option in the store of war surgery and surgery of trauma. The main purpose of our investigation was to specify the percentage of the injured who need DCS. We performed retrospective study of the patients in the combat operations in Chechnya (1994-2002) and in peacetime (2005-2010). Total lethality in group with the standard surgical approach was 62.3%. It was significantly higher than the lethality in group of patients who underwent DCS - 50.0% (p < 0.05). Thus, the experience of DCS in War Surgery Department confirms that DCS is perspective tendency in treatment of patients with severe and extremely severe trauma, and allows decreasing lethality in 12.3%.

Cooperating with other people is a key achievement in child development and is essential for human culture. We examined whether we could induce 4-year-old children to increase their cooperation with an unfamiliar peer by providing the peers with synchronized motion experience prior to the tasks. Children were randomly assigned to independent treatment and control groups. The treatment of synchronous motion caused children to enhance their cooperation, as measured by the speed of joint task completion, compared with control groups that underwent asynchronous motion or no motion at all. Further analysis suggested that synchronization experience increased intentional communication between peer partners, resulting in increased coordination and cooperation.

2015-03-03

Resting brain spontaneous neural activities across cortical regions have been correlated with specific functional properties in psychiatric groups. Individuals with Internet gaming disorder (IGD) demonstrate impaired executive control. Thus, it is important to examine executive control networks (ECNs) during resting states and their relationships to executive control during task performance. Thirty-five IGD and 36 healthy control participants underwent a resting-state fMRI scan and performed a Stroop task inside and outside of the MRI scanner. Correlations between Stroop effect and functional connectivity among ECN regions of interest (ROIs) were calculated within and between groups. IGD subjects show lower functional connectivity in ECNs than do HC participants during resting state; functional-connectivity measures in ECNs were negatively correlated with Stroop effect and positively correlated with brain activations in executive-control regions across groups. Within groups, negative trends were found between Stroop effect and functional connectivity in ECNs in IGD and HC groups, separately; positive trends were found between functional connectivity in ECNs and brain activations in Stroop task in IGD and HC groups, separately. Higher functional connectivity in ECNs may underlie better executive control and may provide resilience with respect to IGD. Lower functional connectivity in ECNs may represent an important feature in understanding and treating IGD. Copyright © 2013 Elsevier Inc. All rights reserved.

The presentation of myelopathy in patients with the concomitant diagnosis of cervical stenosis (CS) and multiple sclerosis (MS) complicates both diagnosis and treatment because of the similarities of presentation and disease progression. There are only a few published case series that examine this unique patient population. To define the demographic features and presenting symptoms of patients with both MS and CS and to investigate the immediate and long-term outcomes of surgery in patients with MS and CS. Matched cohort-controlled retrospective review of 77 surgical patients in the MS group and 77 surgical patients in the control group. Outcome measures were immediate and long-term postoperative neck pain, radiculopathy, and myelopathy; Nurick Disability and modified Japanese Orthopaedic Association scores were collected as well. Retrospective review was performed for all patients presenting at one institution between January 1996 and July 2011 with coexisting diagnoses of MS and CS who had presenting symptoms of myelopathy and who then underwent cervical decompression surgery. Each study patient was individually matched to a control patient of the same gender and age that did not have MS, but that did have cervical spondylotic myelopathy or myeloradiculopathy. Each control patient underwent the same surgical procedure within the same year. A total of 154 patients were reviewed, including 77 MS patients and 77 control patients, for an average follow-up of 58 months and 49 months, respectively. Patients in the control group were more likely to have preoperative neck pain (78% vs. 47%; p=.0001) and preoperative radiculopathy (90% vs. 75%; p=.03) than their counterparts in the MS group. Patients in the MS group had a significantly lower rate of postoperative resolution of myelopathic symptoms in both the short-term (39% in the MS group did not improve vs. 23% in the control group; p=.04) and the long-term (44% in the MS group did not improve vs. 19% in the control group; p=.004). Preoperative myelopathy scores were worse for the MS cohort as compared with the control cohort (1.8 vs. 1.2 in the Nurick scale, p<.0001; 13.7 vs. 15.0 in the modified Japanese Orthopaedic Association scale, p=.002). This difference in scores became even greater at the last follow-up visit with Nurick scores of 2.4 versus 0.9 (p<.0001) and modified Japanese Orthopaedic Association scores of 16.3 versus 12.4 (p<.0001) for the MS and control patients, respectively. Myelopathic patients with coexisting MS and CS improve after surgery, although at a lower rate and to a lesser degree than those without MS. Therefore, surgery should be considered for these patients. MS patients should be informed that myelopathy symptoms are less likely to be alleviated completely or may only be alleviated temporarily because of progression of MS and that surgery can help alleviate neck pain and radicular symptoms.

Radical prostatectomy is associated with perioperative bleeding and multiple transfusions. Abdominal obesity is a perioperative risk factor. We suggest that the adipocytes have a protective effect in oncological patients undergoing radical prostatectomy. The aim was to evaluate the effect of waist-hip ratio (WHR) on the amount of bleeding and perioperative transfusion requirements in oncological patients undergoing radical prostatectomy. We performed a cohort study in 156 patients. We had two groups: the control group (WHR<0.95) and the problem group (WHR≥0.95). Blood loss and fractions transfused during surgery and in the postoperative period were recorded. In the analysis of variables, for descriptive statistics we used measures of central tendency and dispersion. Inferential statistics was obtained by chi square, Student's t test, Mann-Whitney U and ANOVA. A p<0.05 was significant. We found significant differences in weight, body mass index, waist, WHR, perioperative bleeding, fractions transfused, permanence of the catheter, and hospital days. Patients who underwent radical prostatectomy with a WHR≥0.95 had a magnitude of perioperative bleeding and transfusion requirements with a WHR<0.95.

To determine the effect of intracoronary transfer of superparamagnetic iron oxide (SPIO) labeled heme oxygenase-1 (HO-1) overexpressed bone marrow stromal cells (BMSCs) in a porcine myocardial ischemia/reperfusion model. Cell apoptosis was assayed and supernatant cytokine concentrations were measured in BMSCs that underwent hypoxia/reoxygen in vitro. Female mini-swines that underwent 1 h LAD occlusion followed by 1 h reperfusion were randomly allocated to receive intracoronary saline (control), 1 x 10(7) SPIO-labeled BMSCs transfected with pcDNA3.1-Lacz plasmid (Lacz-BMSCs), pcDNA3.1-human HO-1 (HO-1-BMSCs), pcDNA3.1-hHO-1 pretreated with a HO inhibitor, tin protoporphyrin (SnPP, n = 10 each). MRI and postmortem histological analysis were made at 1 week or 3 months thereafter. Post hypoxia/reoxygen in vitro, apoptosis was significantly reduced, supernatant VEGF significantly increased while TNF-alpha and IL-6 significantly reduced in HO-1-BMSCs group compared with Lacz-BMSCs group (all p < 0.05). Myocardial expression of VEGF was significantly higher in HO-1-BMSCs than in Lacz-BMSCs group at 1 week post transplantation (all p < 0.05). Signal voids induced by the SPIO were detected in the peri-infarction region in all BMSC groups at 1 week but not at 3 months post transplantation and the extent of the hypointense signal was the highest in HO-1-BMSCs group, and histological analysis showed that signal voids represented cardiac macrophages that engulfed the SPIO-labeled BMSCs. Pretreatment with SnPP significantly attenuated the beneficial effects of HO-1-BMSCs. Transplantation of HO-1-overexpressed BMSCs significantly enhanced the beneficial effects of BMSCs on improving cardiac function in this model.

Purpose: Vestibular schwannomas (VS) are increasingly diagnosed in patients with normal hearing because of advances in magnetic resonance imaging. We sought to evaluate whether stereotactic radiosurgery (SRS) performed earlier after diagnosis improved long-term hearing preservation in this population. Methods and Materials: We queried our quality assessment registry and found the records of 1134 acoustic neuroma patients who underwent SRS during a 15-year period (1997-2011). We identified 88 patients who had VS but normal hearing with no subjective hearing loss at the time of diagnosis. All patients were Gardner-Robertson (GR) class I at the time of SRS. Fifty-seven patients underwent earlymore » (≤2 years from diagnosis) SRS and 31 patients underwent late (>2 years after diagnosis) SRS. At a median follow-up time of 75 months, we evaluated patient outcomes. Results: Tumor control rates (decreased or stable in size) were similar in the early (95%) and late (90%) treatment groups (P=.73). Patients in the early treatment group retained serviceable (GR class I/II) hearing and normal (GR class I) hearing longer than did patients in the late treatment group (serviceable hearing, P=.006; normal hearing, P<.0001, respectively). At 5 years after SRS, an estimated 88% of the early treatment group retained serviceable hearing and 77% retained normal hearing, compared with 55% with serviceable hearing and 33% with normal hearing in the late treatment group. Conclusions: SRS within 2 years after diagnosis of VS in normal hearing patients resulted in improved retention of all hearing measures compared with later SRS.« less

Both RA and control groups were divided into two subgroups as dry eye (DE) (Schirmer test with topical anesthesia (STA) ≤ 5 mm) and without DE (STA > 5 mm). Pachymetric measurements and the mean corneal volume were significantly lower in RA group (p < 0.001). Disease duration was negatively correlated with pachymetric measurements in RA group. Pachymetric measurements and corneal volume of RA patients with DE were significantly lower than all the other subgroups. Control subgroups with or without DE were similar in pachymetric measurements and corneal volume. The results suggest that RA patients have thinner corneas compared to control subjects that may be affected by disease duration. Furthermore, coexistence of DE and RA seems to aggravate the thinning of cornea as well.

We sought to compare intercellular space diameter in children with non-erosive and erosive reflux disease, and a control group. We also aimed to characterize the reflux pattern in erosive and non-erosive reflux disease patients, and to explore the relationship between intercellular space diameter values and reflux parameters. Twenty-four children with non-erosive reflux disease, 20 with erosive reflux disease, and 10 controls were prospectively studied. All patients and controls underwent upper endoscopy. Biopsies were taken at 2-3 cm above the Z-line, and intercellular space diameter was measured using transmission electron microscopy. Non-erosive and erosive reflux disease patients underwent impedance-pH monitoring. Mean intercellular space diameter values were significantly higher in both non-erosive (0.9 ± 0.2 μm) and erosive reflux disease (1 ± 0.2 μm) compared to controls (0.5 ± 0.2 μm, p<0.01). No difference was found between the two patient groups. Acid exposure time, the number of acid, weakly acidic and weakly alkaline reflux events did not differ between the two patient groups. No difference was found in the mean intercellular space diameter between non-erosive reflux disease children with and without abnormal acid exposure time (1 ± 0.3 vs. 0.9 ± 0.2 μm). No correlation was found between any reflux parameter and intercellular space diameter values. Dilated intercellular space diameter seems to be a useful and objective marker of oesophageal damage in paediatric gastro-oesophageal reflux disease, regardless of acid exposure. In childhood, different gastro-oesophageal reflux disease phenotypes cannot be discriminated on the basis of reflux pattern. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l.

Tonsillectomy and tonsillectomy with adenoidectomy are among the most common surgical procedures in otolaryngology practice. Gastroesophageal reflux was identified as a risk factor for complications in tonsillectomy. This prospective study was designed to assess the role of reflux in the development of complications following tonsillectomy in pediatric patients. Children (n = 60) who underwent tonsillectomy with adenoidectomy were divided into two groups, i.e., the laryngopharyngeal reflux (LPR) group and control group. Patients with LPR were identified by reflux symptom index and reflux finding score. Pain, hemorrhage, fever, nausea, vomiting, fever, dehydration, infection, and pulmonary problems were evaluated post operatively. The mean lengths of hospital stay were 2.11 days in the reflux group and 1.05 days in the control group. The difference was statistically significant. Visual analogue scores of both groups were similar on day 1 but it was significantly higher on day 7 and 14 in LPR group. Nausea and vomiting rates were 11.1 and 9.5 % for the patients in the LPR group and the controls, respectively. The difference between the two groups was not significant. The mean fever was 37.6 °C in the reflux group and 37.3 °C in the controls, which were not significantly different. 19 % of the controls and 22 % of the LPR group patients were readmitted. This difference was not statistically significant. There were two cases of bleeding in the reflux group, while no bleeding occurred in the control group. This difference was significant statistically. LPR is a risk factor for complications following tonsillectomy.

Purpose: Perirectal spacing, whereby biomaterials are placed between the prostate and rectum, shows promise in reducing rectal dose during prostate cancer radiation therapy. A prospective multicenter randomized controlled pivotal trial was performed to assess outcomes following absorbable spacer (SpaceOAR system) implantation. Methods and Materials: Overall, 222 patients with clinical stage T1 or T2 prostate cancer underwent computed tomography (CT) and magnetic resonance imaging (MRI) scans for treatment planning, followed with fiducial marker placement, and were randomized to receive spacer injection or no injection (control). Patients received postprocedure CT and MRI planning scans and underwent image guided intensity modulated radiation therapymore » (79.2 Gy in 1.8-Gy fractions). Spacer safety and impact on rectal irradiation, toxicity, and quality of life were assessed throughout 15 months. Results: Spacer application was rated as “easy” or “very easy” 98.7% of the time, with a 99% hydrogel placement success rate. Perirectal spaces were 12.6 ± 3.9 mm and 1.6 ± 2.0 mm in the spacer and control groups, respectively. There were no device-related adverse events, rectal perforations, serious bleeding, or infections within either group. Pre-to postspacer plans had a significant reduction in mean rectal V70 (12.4% to 3.3%, P<.0001). Overall acute rectal adverse event rates were similar between groups, with fewer spacer patients experiencing rectal pain (P=.02). A significant reduction in late (3-15 months) rectal toxicity severity in the spacer group was observed (P=.04), with a 2.0% and 7.0% late rectal toxicity incidence in the spacer and control groups, respectively. There was no late rectal toxicity greater than grade 1 in the spacer group. At 15 months 11.6% and 21.4% of spacer and control patients, respectively, experienced 10-point declines in bowel quality of life. MRI scans at 12 months verified spacer absorption. Conclusions: Spacer application was well tolerated. Increased perirectal space reduced rectal irradiation, reduced rectal toxicity severity, and decreased rates of patients experiencing declines in bowel quality of life. The spacer appears to be an effective tool, potentially enabling advanced prostate RT protocols.« less

Acute respiratory distress syndrome causes a heterogeneous lung injury, and without protective mechanical ventilation a secondary ventilator-induced lung injury can occur. To ventilate noncompliant lung regions, high inflation pressures are required to 'pop open' the injured alveoli. The temporal impact, however, of these elevated pressures on normal alveolar mechanics (that is, the dynamic change in alveolar size and shape during ventilation) is unknown. In the present study we found that ventilating the normal lung with high peak pressure (45 cmH(2)0) and low positive end-expiratory pressure (PEEP of 3 cmH(2)O) did not initially result in altered alveolar mechanics, but alveolar instability developed over time. Anesthetized rats underwent tracheostomy, were placed on pressure control ventilation, and underwent sternotomy. Rats were then assigned to one of three ventilation strategies: control group (n = 3, P control = 14 cmH(2)O, PEEP = 3 cmH(2)O), high pressure/low PEEP group (n = 6, P control = 45 cmH(2)O, PEEP = 3 cmH(2)O), and high pressure/high PEEP group (n = 5, P control = 45 cmH(2)O, PEEP = 10 cmH(2)O). In vivo microscopic footage of subpleural alveolar stability (that is, recruitment/derecruitment) was taken at baseline and than every 15 minutes for 90 minutes following ventilator adjustments. Alveolar recruitment/derecruitment was determined by measuring the area of individual alveoli at peak inspiration (I) and end expiration (E) by computer image analysis. Alveolar recruitment/derecruitment was quantified by the percentage change in alveolar area during tidal ventilation (%I - E Delta). Alveoli were stable in the control group for the entire experiment (low %I - E Delta). Alveoli in the high pressure/low PEEP group were initially stable (low %I - E Delta), but with time alveolar recruitment/derecruitment developed. The development of alveolar instability in the high pressure/low PEEP group was associated with histologic lung injury. A large change in lung volume with each breath will, in time, lead to unstable alveoli and pulmonary damage. Reducing the change in lung volume by increasing the PEEP, even with high inflation pressure, prevents alveolar instability and reduces injury. We speculate that ventilation with large changes in lung volume over time results in surfactant deactivation, which leads to alveolar instability.

Pancreatic neuroendocrine tumors (PNETs) account for 1-2% of all pancreatic neoplasms. Nonfunctioning PNETs (NF-PNETs) account for 60-90% of all PNETs. Laparoscopic distal pancreatectomy (LDP) is becoming the treatment of choice for benign lesions in the body and tail of the pancreas. However, LDP has not yet been widely accepted as the gold standard for NF-PNETs. The purpose of this study is to evaluate the clinical and oncologic outcomes after laparoscopic versus open distal pancreatectomy (ODP) for NF-PNETs. Between April 1995 and September 2016, 94 patients with NF-PNETs underwent open or laparoscopic distal pancreatectomy at Samsung Medical Center. Patients were divided into two groups: those who underwent LDP and those who underwent ODP. Both groups were compared in terms of clinical and oncologic variables. LDP patients had a significantly shorter hospital stay compared with ODP patients, amounting to a mean difference of 2 days (p < 0.001). Overall complication rates did not differ significantly between the ODP and LDP groups (p = 0.379). The 3-year overall survival rates in the ODP and LDP groups were 93.7 and 100%, respectively (p = 0.069). In this study, LDP for NF-PNETs had similar oncologic outcomes compared with ODP. In addition, LDP was associated with a shorter hospital stay compared with ODP. Therefore, LDP is a safe and effective procedure for patients with NF-PNETs. A multicenter study and a randomized controlled trial are needed to better assess the clinical and oncologic outcomes.

Giant-cell arteritis commonly relapses when glucocorticoids are tapered, and the prolonged use of glucocorticoids is associated with side effects. The effect of the interleukin-6 receptor alpha inhibitor tocilizumab on the rates of relapse during glucocorticoid tapering was studied in patients with giant-cell arteritis. In this 1-year trial, we randomly assigned 251 patients, in a 2:1:1:1 ratio, to receive subcutaneous tocilizumab (at a dose of 162 mg) weekly or every other week, combined with a 26-week prednisone taper, or placebo combined with a prednisone taper over a period of either 26 weeks or 52 weeks. The primary outcome was the rate of sustained glucocorticoid-free remission at week 52 in each tocilizumab group as compared with the rate in the placebo group that underwent the 26-week prednisone taper. The key secondary outcome was the rate of remission in each tocilizumab group as compared with the placebo group that underwent the 52-week prednisone taper. Dosing of prednisone and safety were also assessed. Sustained remission at week 52 occurred in 56% of the patients treated with tocilizumab weekly and in 53% of those treated with tocilizumab every other week, as compared with 14% of those in the placebo group that underwent the 26-week prednisone taper and 18% of those in the placebo group that underwent the 52-week prednisone taper (P<0.001 for the comparisons of either active treatment with placebo). The cumulative median prednisone dose over the 52-week period was 1862 mg in each tocilizumab group, as compared with 3296 mg in the placebo group that underwent the 26-week taper (P<0.001 for both comparisons) and 3818 mg in the placebo group that underwent the 52-week taper (P<0.001 for both comparisons). Serious adverse events occurred in 15% of the patients in the group that received tocilizumab weekly, 14% of those in the group that received tocilizumab every other week, 22% of those in the placebo group that underwent the 26-week taper, and 25% of those in the placebo group that underwent the 52-week taper. Anterior ischemic optic neuropathy developed in one patient in the group that received tocilizumab every other week. Tocilizumab, received weekly or every other week, combined with a 26-week prednisone taper was superior to either 26-week or 52-week prednisone tapering plus placebo with regard to sustained glucocorticoid-free remission in patients with giant-cell arteritis. Longer follow-up is necessary to determine the durability of remission and safety of tocilizumab. (Funded by F. Hoffmann-La Roche; ClinicalTrials.gov number, NCT01791153 .).

muscle strength and power are two factors affecting balance. The impact of muscle strength and power on postural control has not been fully explored among different age strata over sixty. the aim of the present study was to assess the muscle strength and power of elderly women in different age groups and determine their correlation with postural control. eighty women were divided into four groups: the young 18-30 age group (n=20); the 60-64 age group (n=20); the 65-69 age group (n=20); and the 70-74 age group (n=20). The participants underwent maximum strength (one repetition maximum or 1-RM) and muscle power tests to assess the knee extensor and flexor muscles at 40%, 70%, and 90% 1-RM intensity. The time required by participants to recover their balance after disturbing their base of support was also assessed. the elderly women in the 60-64, 65-69, and 70-74 age groups exhibited similar muscle strength, power, and postural control (p>0.05); however, these values were lower than those of the young group (p<0.05) as expected. There was a correlation between muscle strength and power and the postural control performance (p<0.05). despite the age difference, elderly women aged 60 to 74 years exhibited similar abilities to generate strength and power with their lower limbs, and this ability could be one factor that explains the similar postural control shown by these women.

Unilateral lesions to the medial forebrain bundle with 6-hydroxydopamine (6-OHDA) lead to force and timing deficits during a complex licking task. We hypothesized that training targeting tongue force generation during licking would improve timing and force measures and also lead to striatal dopamine sparing. Nine month-old male Fisher344/Brown Norway rats were used in this experiment. Sixteen rats were in the control condition and received tongue exercise (n=8) or no exercise (n=8). Fourteen rats were in the 6-OHDA lesion condition and underwent tongue exercise (n=7) and or no exercise (n=7). Following 4 weeks of training and post-training measures, all animals underwent bilateral stimulation of the hypoglossal nerves to measure muscle contractile properties and were then transcardially perfused and brain tissues collected for immunohistochemistry to examine striatal dopamine content. Results demonstrated that exercise animals performed better for maximal force, average force, and press rate than their no-exercise counterparts, and the 6-OHDA animals that underwent exercise performed as well as the Control No Exercise group. Interestingly, there were no group differences for tetanic muscle force, despite behavioral recovery of forces. Additionally, behavioral and neurochemical analyses indicate that there were no differences in striatal dopamine. Thus, targeted exercise can improve tongue force and timing deficits related to 6-OHDA lesions and this exercise likely has a central, versus peripheral (muscle strength) mechanism. However, this mechanism is not related to sparing of striatal dopamine content. Copyright © 2013 Elsevier B.V. All rights reserved.

Objective Examine the association between body mass index (BMI) and superior canal dehiscence (SCD) among patients who have undergone surgical repair for superior canal dehiscence. Study Design Retrospective comparison study. Setting Neurotology tertiary care center. Subjects and Methods Retrospective review of consecutive adult patients evaluated at our institution for SCD syndrome between November 2006 and August 2015. A control group who underwent imaging within the same period for reasons other than SCD was also included. Patient demographics, weight, and height were examined. We performed multiple subgroup analyses to investigate the relationship of BMI, surgery vs no surgery, and correlation between patient BMI and SCD size. Results Of the 268 patients with SCD, 99 underwent surgery; 96 of these patients had complete medical records and were eligible for inclusion. Eighty-eight patients were noted to have arcuate eminence defects, and the mean BMI of this surgical cohort was 28.09 ± 5.26 kg/m 2 . Nonsurgically treated patients with SCD with available data (n = 94) had a mean BMI of 27.97 ± 6.95 kg/m 2 . A control group of 204 patients who underwent computed tomography for non-SCD-related causes was analyzed, of whom 155 had available data with a mean BMI of 27.91 ± 6.38 kg/m 2 . Conclusion We demonstrate that adult patients who undergo surgery for SCD are not obese (mean BMI <30), and size of dehiscence poorly correlates with BMI. Our observations call into question the proposed theory that patient weight is a risk factor for the development of symptomatic SCD involving the arcuate eminence.

Osteoporosis (OP) and osteoporotic fracture are major public health issues for society; the burden for the affected individual is also high. Previous studies have shown that pulsed wave low-level laser therapy (PW LLLT) has osteogenic effects. This study intended to evaluate the impacts of PW LLLT on the cortical bone of osteoporotic rats' tibias in two experimental models, ovariectomized and dexamethasone-treated. We divided the rats into four ovariectomized induced OP (OVX-d) and four dexamethasone-treated (glucocorticoid-induced OP, GIOP) groups. A healthy (H) group of rats was considered for baseline evaluations. At 14 weeks following ovariectomy, we subdivided the OVX-d rats into the following groups: (i) control which had OP, (ii) OVX-d rats treated with alendronate (1 mg/kg), (iii) OVX-d rats treated with LLLT, and (iv) OVX-d rats treated with alendronate and PW LLLT. The remaining rats received dexamethasone over a 5-week period and were also subdivided into four groups: (i) control rats treated with intramuscular (i.m.) injections of distilled water (vehicle), (ii) rats treated with subcutaneous alendronate injections (1 mg/kg), (iii) laser-treated rats, and (iv) rats simultaneously treated with laser and alendronate. The rats received alendronate for 30 days and underwent PW LLLT (890 nm, 80 Hz, 0.972 J/cm(2)) three times per week during 8 weeks. Then, the right tibias were extracted and underwent a stereological analysis of histological parameters and real-time polymerase chain reaction (RT-PCR). A significant increase in cortical bone volume (mm(3)) existed in all study groups compared to the healthy rats. There were significant decreases in trabecular bone volume (mm(3)) in all study groups compared to the group of healthy rats. The control rats with OP and rats from the vehicle group showed significantly increased osteoclast numbers compared to most other groups. Alendronate significantly decreased osteoclast numbers in osteoporotic rats. Concurrent treatments (compounded by PW LLLT and alendronate) produce the same effect on osteoporotic bone.

The poor healing capacity of a completely ruptured anterior cruciate ligament (ACL) has been attributed to an insufficient vascular supply, cellular metabolism, and deficient premature scaffold formation because of the unique intra-articular environment. However, previous studies have focused on intra-articular factors without considering extra-articular factors, including the biomechanical aspects of ACL-deficient knees. Changing the joint kinematics of an ACL-ruptured knee will improve cellular biological responses and lead to spontaneous healing through the mechanotransduction mechanism. Controlled laboratory study. A total of 66 skeletally mature Wistar rats were randomly assigned to a sham-operated group (SO), ACL-transection group (ACL-T), controlled abnormal movement group (CAM), and an intact group (IN). The ACL was completely transected at the midportion in the ACL-T and CAM groups, and the CAM group underwent extra-articular braking to control for abnormal tibial translation. The SO group underwent skin and joint capsule incisions and tibial drilling, without ACL transection and extra-articular braking. The animals were allowed full cage activity until sacrifice at 1, 2, 4, 6, and 8 weeks postoperatively for histological, molecular biological, and biomechanical assessment. All injured ACLs in the ACL-T group were not healed, but those in the CAM group healed spontaneously, showing a typical ligament healing response. Regarding the molecular biological response, there was an upregulation of anabolic factors (ie, transforming growth factor-β) and downregulation of catabolic factors (ie, matrix metalloproteinase). Examination of the mechanical properties at 8 weeks after injury showed that >50% of the strength of the intact ACL had returned. Our results suggest that changing the joint kinematics of knees with a ruptured ACL alters the molecular biological responses and leads to spontaneous healing. These data support our hypothesis that the mechanotransduction mechanism mediates molecular responses and determines whether the ACL will heal. Elucidating the relationship between the mechanotransduction mechanism and healing responses in knees with completely ruptured ACLs may result in the development of novel nonsurgical treatment that enables the ACL to spontaneously heal in patients who are not suitable for reconstruction. © 2016 The Author(s).

To compare the early psychological changes of cleft lip and palate (CLP) and noncleft patients after maxillofacial corrective surgery, including maxillary distraction osteogenesis and conventional orthognathic surgery. Nine CLP patients were compared with a group of 9 non-CLP patients having similar dentofacial deformities in a prospective longitudinal cohort study. Five of the CLP patients underwent maxillary distraction osteogenesis and 4 underwent conventional orthognathic surgery. A control group of 9 noncleft patients received conventional orthognathic surgery. All patients completed a set of questionnaires to enable their psychological profile to be assessed. The data were collected immediately before surgery (T1), and at 3 weeks (T2) and 12 weeks (T3) after surgery. The CLP patients treated with distraction osteogenesis were happier, but had a higher level of social anxiety and distress than the CLP patients receiving conventional orthognathic surgery. On the other hand, the CLP patients overall were happier, with lower social anxiety and distress, than the noncleft control group. The CLP patients showed a higher level of parental self-esteem than the noncleft patients. This preliminary study shows that CLP patients were generally happier, and had a higher level of parental support, than normal patients suffering from dentofacial deformities. Maxillary distraction osteogenesis seemed to induce a higher level of anxiety and distress in CLP patients than conventional orthognathic surgery in both cleft and noncleft patients.

In this rat model study we evaluated whether pretreatment with simvastatin affects the severity of acute lung injury caused by intestinal ischemia-reperfusion (I/R). Twenty-four animals were randomly allocated to three equal groups (sham, control, simvastatin). The simvastatin group was pretreated with simvastatin 10 mg x kg(-1) x day(-1) for 3 days, whereas the other groups received placebo. The simvastatin and control groups underwent 60 min of superior mesenteric artery occlusion and 90 min of reperfusion. Compared with the simvastatin group, the control group exhibited significantly more severe intestinal I/R-induced acute lung injury, as indicated by lower Pao2 and oxygen saturation (P = 0.01 and P = 0.005, respectively) and higher mean values for neutrophil infiltration of the lungs (P = 0.003), total lung histopathologic injury score (P = 0.003), lung wet-to-dry weight ratio (P = 0.009), and lung-tissue malondialdehyde levels (P = 0.016). The control and simvastatin groups had similar serum levels and similar bronchoalveolar lavage fluid levels of cytokines (interleukin-1, interleukin-6, and tumor necrosis factor-alpha) and P-selectin at all measurements, except for a significantly higher level of bronchoalveolar lavage fluid P-selectin in the control group (P = 0.006). Pretreatment with simvastatin reduces the severity of acute lung injury induced by intestinal I/R in rats.

To evaluate the efficacy of local compression and topical epinephrine in controlling perioperative bleeding during open radical retropubic prostatectomy (ORRP) and its impact on the degree of urinary extravasation on initial postoperative cystogram. Between September 2005 to March 2009, 476 men underwent ORRP performed by a single surgeon. Group 1 (n = 200) underwent ORRP between September 2005 and November 2006 without pelvic compression; Group 2 (n = 76) underwent ORRP between November 2006 and May 2007 and a dry laparotomy pad was positioned in the pelvis immediately prior to abdominal wound closure; Group 3 (n = 200) underwent ORRP between May 2007 and March 2009 with a epinephrine soaked laparotomy pad positioned in the pelvis prior to abdominal wound closure. Hematocrit values were obtained prior to anesthesia induction, upon arrival in the recovery room and at hospital discharge in order to estimate intraoperative and postoperative bleeding. The number of allogenic and autologous units transfused was recorded. The utility of compressing the pelvis with a pad was examined by comparing estimated postoperative bleeding between Group 1 versus Groups 2 and 3 and the hemostatic utility of soaking the pad in epinephrine was examined by comparing Group 2 versus 3. Systolic and diastolic blood pressure and pulse measurements were obtained at baseline and 5 and 10 minutes after introducing the epinephrine pad. The relationship between estimated blood loss and degree of extravasation on initial postoperative cystogram was investigated. Estimated intraoperative, postoperative and total blood loss (mean change in Hct) was 12.2, 2.3, 14.2, in Group 1, 10.0, 1.5, 11.1 in Group 2, and 10.8, 2.1, and 12.6 in Group 3. Estimated intraoperative and total blood loss was significantly less in the men treated with a compression pad (Groups 2 and 3) versus no pad (Group 1). There were no significant differences in number of patients transfused, the number of units transfused or the degree of extravasation on postoperative cystograms between Group 1 versus Group 2 and 3 or Group 2 versus 3. However, postoperative bleeding was significantly less in Group 2 compared to Group 3. Mean systolic and diastolic blood pressure and pulse values were unchanged from baseline after epinephrine use. Local compression of the pelvis with or without epinephrine prior to abdominal wound closure does not appear to have beneficial effects on reducing postoperative bleeding and decreasing the degree of urinary extravasation on cystogram following ORRP. While the use of topical epinephrine appears to be safe and relatively inexpensive, at the concentrations used in our study it does not appear to facilitate postoperative hemostasis.

Introduction Resection of perihilar cholangiocarcinoma (PHC) entails high-risk surgery with substantial postoperative mortality reported up to 18%, even in specialized centers. The aim of this study was to compare outcomes of PHC patients who underwent associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) to patients with a small functional liver remnant who underwent resection without ALPSS. Methods All patients who underwent ALPPS for PHC were identified from the international ALPPS registry and matched controls were selected from a standard resection cohort from two centers based on future remnant liver size. Outcomes included morbidity, mortality, and overall survival. Results Of the 37 patients who had undergone ALPPS for PHC in the registry, 29 had sufficient data for analyses. ALPPS for PHC was associated with a 48% (14/29) 90-day mortality and median OS of 6 months. A total of 257 patients underwent major liver resection for PHC without ALPPS. The 90-day mortality was 13% and median OS 46 months. The 29 ALPPS patients were matched to 29 patients resected without ALPPS, with similar future liver remnant volume (P=0.480). Mortality in the matched control group was 24% (P=0.100) and median OS was 27 months (P = 0.064). Discussion Outcomes of ALPPS for PHC appear inferior when compared to standard extended resections in high-risk patients. Considering these outcomes, portal vein embolization should remain the preferred method to increase future remnant liver volume in PHC patients. ALPPS is not recommended for PHC due to the 48% 90-day mortality in expert centers. PMID:28279621

To investigate and compare the cytopathological and clinical effects of amniotic membrane transplantation (AMT) and oral mucosal membrane transplantation (OMMT) in socket contraction. Twelve patients who could not be fitted with ocular prosthesis due to socket contracture were included in this study. Seven patients underwent AMT and 5 patients underwent OMMT. Thirteen patients who had healthy sockets were included as control group. Depth of inferior fornix, degree of inflammation, extent of the socket contracture and socket volume were measured in the preoperative period and at sixth and twelfth weeks postoperatively. Impression cytology of conjunctival fornices and tear transforming growth factor beta-1 (TGFβ1) levels were determined. In the AMT group, socket volume and lower fornix depth values were significantly higher (P=0.030 and P=0.004 respectively) and inflammation levels and impression cytology stages (P=0.037 and P=0.022 respectively) were significantly lower in postoperative period compared to preoperative period. In the OMMT group, no statistical differences were found in terms of clinical parameters, inflammation levels and impression cytology stages of preoperative versus postoperative values. Preoperative tear TGFβ1 levels were higher in AMT and OMMT groups compared to the control group (25.5 ng/mL, 26.3 ng/mL and 21.7 ng/mL respectively). Decreased tear TGFβ1 levels were observed in both the AMT and OMMT groups postoperatively (median decrease value=2.1 ng/mL and 2.7 ng/mL respectively). AMT is associated with postoperative improvement in inferior fornix depth, socket volume, inflammation and impression cytology levels and may be a more proper alternative method than OMMT in the management of socket contracture.

Several biodegradable materials have been experimented for penile enhancement, but none show the potential for clinical use. This study was designed to use porcine small intestinal submucosa (SIS) augmenting the normal tunica albuginea to increase the functional girth of the rat penis. In all, 20 adult male Sprague-Dawley rats constituted the study population. The animals were divided into two groups: group 1 consisted of the control (n=10) and group 2 (n=10) consisted of rats that underwent penile enhancement by a longitudinal I-shaped incision of the tunica albuginea on both sides, and the dissection of the plane between tunica albuginea and cavernosal tissue was carried out (n=10). The incision was then patched with a 3 x 10 mm2 piece of SIS, using a 6/0 nylon suture material. The penile length and mid-circumference were then measured using a Vernier Caliper before and 2 months after surgery. All rat penises underwent histological examination using Masson's trichome and Verhoff's van Giesen's stain for collagen and elastic fibers. The penile length, mid-circumference and degree of fibrosis score were expressed as mean+/-s.e. (standard error) and analyzed using a Wilcoxon rank-sum test. A statistical significance was accepted at P-value < or =0.05. Our results showed similar preoperative penile length and circumference in both groups. However, 2 months after the surgery, the mean penile circumference of the SIS group has grown significantly larger than the control group, while the mean penile length remained unchanged. The histological study of the rat penises revealed minimal amounts of fibrosis under the graft, and the elastic fibers of the graft showed orientation in a circular manner. In conclusion, SIS appears promising for material use in a penile enhancement.

The aim of this study was to evaluate the effect of differential training-based occupational therapy on the recovery of arm function and to compare these data with the results obtained after conventional occupational therapy. A total of 27 patients who had suffered a cerebral infarction in the left brain hemisphere were recruited for the study. There were 9 men (33.33%) and 18 women (66.67%). All the patients had paresis of the right arm. The patients were divided into 2 groups: the control group comprised 15 patients who were given conventional occupational therapy (5 times per week) and the study group consisted of 12 patients who underwent conventional occupational therapy (3 times per week) along with occupational therapy based on differential training (2 times per week). In the control group, the mean performance time of only 2 tasks, i.e., flip cards and fold towel, improved significantly (P<0.05), while significant deterioration in the mean performance time of the task "lift can" was observed (P<0.05). In the study group, the mean performance time of all the tasks except for forearm to box (side), hand to box (front), and lift paperclip improved significantly (P<0.05), and no deterioration in arm function was observed. Both patients' groups improved arm function after occupational therapy sessions, but the patients who underwent conventional occupational therapy along with differential training-based occupational therapy recovered their arm function more effectively than their counterparts after conventional occupational therapy.

Purpose To investigate whether initial diagnostic laparoscopy can prevent futile primary cytoreductive surgery (PCS) by identifying patients with advanced-stage ovarian cancer in whom > 1 cm of residual disease will be left after PCS. Patients and Methods This multicenter, randomized controlled trial was undertaken within eight gynecologic cancer centers in the Netherlands. Patients with suspected advanced-stage ovarian cancer who qualified for PCS were eligible. Participating patients were randomly assigned to either laparoscopy or PCS. Laparoscopy was used to guide selection of primary treatment: either primary surgery or neoadjuvant chemotherapy followed by interval surgery. The primary outcome was futile laparotomy, defined as a PCS with residual disease of > 1 cm. Primary analyses were performed according to the intention-to-treat principle. Results Between May 2011 and February 2015, 201 participants were included, of whom 102 were assigned to diagnostic laparoscopy and 99 to primary surgery. In the laparoscopy group, 63 (62%) of 102 patients underwent PCS versus 93 (94%) of 99 patients in the primary surgery group. Futile laparotomy occurred in 10 (10%) of 102 patients in the laparoscopy group versus 39 (39%) of 99 patients in the primary surgery group (relative risk, 0.25; 95% CI, 0.13 to 0.47; P < .001). In the laparoscopy group, three (3%) of 102 patients underwent both primary and interval surgery compared with 28 (28%) of 99 patients in the primary surgery group ( P < .001). Conclusion Diagnostic laparoscopy reduced the number of futile laparotomies in patients with suspected advanced-stage ovarian cancer. In women with a plan for PCS, these data suggest that performance of diagnostic laparoscopy first is reasonable and that if cytoreduction to < 1 cm of residual disease seems feasible, to proceed with PCS.

Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease which refers to the presence of hepatic steatosis. Breast cancer is now the most common cancer in women and is the leading cause of death from cancer among women. To assess the relationship between NAFLD and newly diagnosed cases of breast cancer. The results of mammography screening examinations in women referred to the Breast Center, Holy Family Hospital, Nazareth during a 4 year period were collected. We identified cases of women who were newly diagnosed with breast cancer and who underwent abdominal computed tomography (CT) within 1 month of the diagnosis. The control group comprised 73 women with normal mammography and breast ultrasonography who underwent abdominal CT within 3 months from the date of the breast cancer screening during the same study period. The control cases were matched by age and body mass index (BMI). We compared the cases with the controls in terms of the presence of diffuse hepatic fatty liver and other known risk factors for breast cancer. Of the 133 women who were screened, 73 with new diagnosis of breast cancer were eligible for the study. NAFLD was found in 33 of the women with breast cancer and in 12 in the control group (45.2% vs.16.4%, respectively, P = 0.002). Multivariate analysis showed NAFLD (odds ratio 2.82, 95% confidence interval 1.2-5.5, P = 0.016) to be associated with breast cancer. NAFLD is associated with breast cancer.

Background and aim Thoracic radiation therapy (XRT) for cancer is associated with the development of significant coronary artery disease that may require coronary artery bypass grafting surgery (CABG). Contemporary acute surgical outcomes and long-term postoperative survival of patients with prior XRT have not been well characterised. Methods This was a retrospective, single-centre study of patients with a history of thoracic XRT who required CABG and who were propensity matched against 141 controls who underwent CABG over the same time period. The objectives were to assess early CABG outcomes and long-term survival in patients with prior XRT. Results Thirty-eight patients with a history of previous thoracic XRT underwent CABG from 1994 to 2013. The median time from XRT exposure to surgery was 7.9 years (IQR: 2.5–18.4 years). Perioperative adverse events were similar in the XRT group and controls; however, there was a trends lower utilisation of internal mammary artery (IMA) grafts in the XRT group (89%vs98%, P=0.13). After a median postoperative follow-up of 5.4 years (IQR 0.9–9.4 years), no difference in long-term all-cause mortality was observed. Conclusion Patients with prior thoracic XRT who undergo CABG have similar long-term all-cause mortality compared with controls. Isolated CABG after thoracic XRT is not associated with higher perioperative complications, but IMA graft use may be limited by prior XRT. PMID:29531769

Understanding the neural basis of Major Depressive Disorder (MDD) is important for the diagnosis and treatment of this mental disorder. The default mode network (DMN) is considered to be highly involved in the MDD. To find directed interaction between DMN regions associated with the development of MDD, the effective connectivity within the DMN of the MDD patients and matched healthy controls was estimated by using a recently developed spectral dynamic causal modeling. Sixteen patients with MDD and sixteen matched healthy control subjects were included in this study. While the control group underwent the resting state fMRI scan just once, all patients underwent resting state fMRI scans before and after two months' treatment. The spectral dynamic causal modeling was used to estimate directed connections between four DMN nodes. Statistical analysis on connection strengths indicated that efferent connections from the medial frontal cortex (MFC) to posterior cingulate cortex (PCC) and to right parietal cortex (RPC) were significant higher in pretreatment MDD patients than those of the control group. After two-month treatment, the efferent connections from the MFC decreased significantly, while those from the left parietal cortex (LPC) to MFC, PCC and RPC showed a significant increase. These findings suggest that the MFC may play an important role for inhibitory conditioning of the DMN, which was disrupted in MDD patients. It also indicates that disrupted suppressive function of the MFC could be effectively restored after two-month treatment.

This study compared the effects of extracorporeal shock wave therapy (ESWT) and alendronate sodium (alendronate) in osteoarthritis (OA) of rat knees. The control group was subjected to a sham surgery and did not receive either ESWT or alendronate treatment. The OA group underwent anterior cruciate ligament transection (ACLT) and medial meniscectomy (MM) surgery and did not receive either ESWT or alendronate. The ESWT group underwent ACLT and MM surgery and received ESWT after the surgery. The alendronate group received alendronate after ACLT and MM surgery. The evaluations included radiograph, bone mineral density (BMD), serum C-telopeptide collagen II (CTX-II), cartilage oligomeric protein (COMP), alkaline phosphatase and osteocalcin, histopathological examination and immunohistochemical analysis. Radiographs at 12 weeks showed pronounced OA changes in the OA group. The BMD values, CTX-II, COMP, alkaline phosphatase and osteocalcin showed no significant difference between ESWT and alendronate groups. In histopathology, the Mankin and Safranin O scores significantly increased in the OA, ESWT and alendronate groups, but without any significant difference between the ESWT and alendronate groups. In immunohistochemical analysis, the von Willebrand factor (vWF), vascular endothelial factor (VEGF), soluble vascular cell adhesion molecule (sVCAM), proliferating cell nuclear antigen (PCNA), bone morphogenetic protein 2 (BMP-2), and osteocalcin expressions in articular cartilage and subchondral bone showed a significant decrease in the OA group, but no difference was noted between the ESWT and alendronate groups. In conclusion, ESWT and alendronate sodium demonstrate equal protective effects from developing osteoarthritis of the knee in rats.

To compare the safety and efficacy of an inexpensive-modified transobturator vaginal tape procedure with the transobturator tension-free vaginal tape (TVT-O) procedure for the surgical treatment of female stress urinary incontinence (SUI). Patients with SUI were randomly allocated to either the test group receiving the inexpensive-modified transobturator vaginal tape procedure or the control group receiving the GYNECARE TVT-O procedure. Treatment outcomes and Quality-of-life scores were recorded and analyzed between two groups. A total of 156 patients were enrolled in this trial. Eighty patients underwent the modified transobturator vaginal tape procedure. Among them 75(93.8%) were cured and 5(6.2%) were improved. The rest of the 76 patients underwent the GYNECARE TVT-O procedure with a 92% (70 of 76) cure rate and an 8% (6 of 76) improvement rate. No inefficient or aggravated cases occurred in both groups. The success rates between groups had no significant statistic difference (p > 0.05). The operative time, blood loss, hospital stay, and medical cost were significantly lower in the test group (p < 0.01); the increases in Quality-of-life scores were comparable between groups. The modified transobturator vaginal tape procedure is an efficacious and economic surgical treatment for female SUI. Copyright © 2011. Published by Elsevier B.V.

To investigate the clinical advantages of the stent-laparoscopy approach to treat colorectal cancer (CRC) patients with acute colorectal obstruction (ACO). From April 2008 to April 2012, surgery-related parameters, complications, overall survival (OS), and disease-free survival (DFS) of 74 consecutive patients with left-sided CRC presented with ACO who underwent self-expandable metallic stent (SEMS) placement followed by one-stage open (n = 58) or laparoscopic resection (n = 16) were evaluated retrospectively. The stent-laparoscopy group was also compared with a control group of 96 CRC patients who underwent regular laparoscopy without ACO between January 2010 and December 2011 to explore whether SEMS placement influenced the laparoscopic procedure or reduced long-term survival by influencing CRC oncological characteristics. The characteristics of patients among these groups were comparable. The rate of conversion to open surgery was 12.5% in the stent-laparoscopy group. Bowel function recovery and postoperative hospital stay were significantly shorter (3.3 ± 0.9 d vs 4.2 ± 1.5 d and 6.7 ± 1.1 d vs 9.5 ± 6.7 d, P = 0.016 and P = 0.005), and surgical time was significantly longer (152.1 ± 44.4 min vs 127.4 ± 38.4 min, P = 0.045) in the stent-laparoscopy group than in the stent-open group. Surgery-related complications and the rate of admission to the intensive care unit were lower in the stent-laparoscopy group. There were no significant differences in the interval between stenting and surgery, intraoperative blood loss, OS, and DFS between the two stent groups. Compared with those in the stent-laparoscopy group, all surgery-related parameters, complications, OS, and DFS in the control group were comparable. The stent-laparoscopy approach is a feasible, rapid, and minimally invasive option for patients with ACO caused by left-sided CRC and can achieve a favorable long-term prognosis.

To observe the clinical effect of ear point embedding on plasma and effect site concentrations of propofol-remifentanil in elderly patients who underwent abdominal external hernia surgery at the time of consciousness and pain disappearing by target-controlled infusion (TCI) and bispectral index (BIS). Fifty patients who underwent elective abdominal hernia surgery were randomly assigned into an observation group and a control group, 25 cases in each one. In the observation group, 30 minutes before anesthesia induction, Fugugou (Extra), Gan (CO 12 ), Pizhixia (AT 4 ), and Shenmen (TF 4 ) were embedded by auricular needles until the end of surgery, 10 times of counter press each point. In the control group, the same amount of auricular tape was applied until the end of surgery at the same points without stimulation 30 minutes before anesthesia induction. Patients in the two groups were given total intravenous anesthesia, and BIS was monitored by BIS anesthesia depth monitor. Propofol was infused by TCI at a beginning concentration of 1.5μg/L and increased by 0.3μg/L every 30s until the patients lost their consciousness. After that, remifentanil was infused by TCI at a beginning concentration of 2.0μg/L and increased by 0.3μg/L every 30s until the patients had no body reaction to pain stimulation (orbital reflex). Indices were recorded, including mean arterial pressure (MAP), heart rate (HR) and the BIS values, at the time of T 0 (entering into the operation room), T 1 (losing consciousness) and T 2 (pain relief), the plasma and effect site concentrations of propofol at T 1 , the plasma and effect site concentrations of remifentanil at T 2 . After surgery we recorded the total amounts of propofol and remifentanil, surgery time and anesthesia time. At T 1 and T 2 , MAP and HR of the observation group were higher than those of the control group ( P <0.05, P <0.01). At T 1 , the plasma and effect site concentrations of propofol in the observation group were significantly lower than those in the control group ( P <0.05, P <0.01). At T 2 , the plasma and effect site concentrations of remifentanil in the observation group were significantly lower than those in the control group ( P <0.05, P <0.01). There was no significant difference in BIS values at T 1 and T 2 between the two groups (both P >0.05). There was no significant difference in operation time and anesthesia time between the two groups (both P >0.05). The total amount of remifentanil in the observation group was significantly lower than that in the control group ( P <0.01). There was no significant difference in the total amount of propofol between the two groups ( P >0.05). Ear points embedding combined with propofol-remifentanil TCI could reduce the plasma and effect site concentrations of propofol and remifentanil and the total amount of remifentanil in elderly patients with extra-abdominal hernia surgery, and had the effect of assisting sedation and analgesia.

To compare physical fitness between rice farmers with chronic low back pain (CLBP) and a healthy control group. Sixty-eight rice farmers with CLBP were matched according to age and sex with healthy farmers. All subjects underwent nine physical fitness tests for body composition, lifting capacity, static back extensor endurance, leg strength, static abdominal endurance, handgrip strength, hamstring flexibility, posterior leg and back muscles flexibility and abdominal flexibility. There was no significant difference between CLBP and healthy groups for all tests, except the static back extensor endurance. The back extensor endurance times of the CLBP group was significantly lower than that of the control group (p = 0.002). Static back extensor endurance is the deficient physical fitness in CLBP rice farmers. Back extensor endurance training should be emphasized in both prevention and rehabilitation programs.

Deficiencies in balance and strength are common in children and they may lead to injuries. This study investigated the effects of inline skating exercise on balance and strength performance in healthy children. Twenty 11-12-year-old children (8 girls, 12 boys) were assigned to an intervention (n = 10) or a control (n = 10) group. Participants in the intervention group underwent a 4-week inline skating program (2 times/week, 90 min. each) integrated in their physical education lessons. Balance and strength were measured using the Star Excursion Balance test and the countermovement jump test. As compared to the control group, the intervention group significantly improved balance (17-48%, Cohen's d = 0.00-1.49) and jump height (8%, Cohen's d = 0.48). In children, inline skating is a safe, feasible (90% adherence rate), and effective program that can be integrated in physical education lessons to promote balance and strength.

Anterior cruciate ligament (ACL) tears are highly incident injuries in young athletes within our work area. The use of the patellar graft, despite being the treatment of choice, presents post-operative problems such as anterior knee pain, which limits its use and leads to preference being taken for alternative grafts. Our aim was to evaluate if the application of PRGF reduces anterior knee pain in donor site in BTB-ACL reconstruction. 43 patients were included in the double-blinded and randomized clinical trial comparing two patient groups who underwent ACL reconstruction using patellar tendon graft, comparing anterior knee pain with and without the application of PRGF at the donor site after harvesting the graft. The PRGF group showed decreased donor site pain in comparison to the control group, with significant differences in the first two months of follow-up. The application of PRGF decreased donor site pain compared to the control group.

A randomized controlled trial (RCT) investigated patients with gastroesophageal reflux disease (GERD) who were stable and symptomatically controlled with long-term medical therapy to compare ongoing optimized medical therapy with laparoscopic Nissen fundoplication (LNF). Of the 180 patients eligible for randomization, 104 gave informed consent, and 3 withdrew from the study immediately after randomization. The patients randomized to medical therapy received optimized treatment with proton pump inhibitors (PPIs) using a standardized management protocol based on best evidence and published guidelines. The surgical patients underwent LNF by one of four surgeons using a previously published technique. The patients underwent symptom evaluation using the GERD symptom scale (GERSS) and the global visual analog scale (VAS) for overall symptom control. They had 24-h esophageal pH monitoring at baseline and after 3 years. The medical patients were evaluated receiving PPI, and the surgical patients were evaluated not receiving PPI. For the 3-year follow-up assessment, 93 patients were available. At 3 years, surgery was associated with more heartburn-free days, showing a mean difference of -1.35 days per week (p = 0.0077) and a lower VAS score (p = 0.0093) than medical management. Surgical patients reported improved quality of life on the general health subscore of the Medical Outcomes Survey Short Form 36 (SF-36) at 3 years, with a mean difference of -12.19 (p = 0.0124). The groups did not differ significantly in terms of GERSS or acid exposure on 24-h esophageal pH monitoring at 3 years. There were six treatment failures (11.8%) in the surgical group and eight treatment failures (16%) in the medical group by 3 years. For patients whose GERD symptoms are stable and controlled with PPI, continuing medical therapy and laparoscopic antireflux surgery are equally effective, although surgery may result in better symptom control and quality of life.

Purpose The objective of this study was to analyze the feasibility of orthodontic treatment with fixed multibracket dental appliances (FMAs) in patients with Down syndrome (DS). Methods The study sample was formed of 25 patients with DS who underwent orthodontic treatment with FMAs. Dental and skeletal characteristics, aspects of FMA treatment, retainer use and recurrences were analyzed. Results were compared with a control group of healthy, age-, sex- and PAR index-matched individuals. Results All the controls underwent a single desensitization session, whereas 2-3 sessions were necessary in 11 patients with DS (p < 0.001). All the controls underwent bimaxillary treatment, compared with 11 patients with DS (p < 0.001). Only 8 patients with DS wore intermaxillary elastics, compared with 19 controls (p = 0.004). Complications were more common in patients with DS than in controls (p = 0.003), due particularly to traumatic ulcers development. There were more failures during the maintenance phase in patients with DS than in controls (p = 0.001). The mean duration of treatment was 37 months in patients with DS and 23 months in controls. More cemented retainers were used in the controls than in patients with DS (p = 0.050). Conclusions It is possible to perform orthodontic treatment with FMAs in patients with DS, although treatment may take longer than usual and the frequency of complications is higher than in controls. Implications for Rehabilitation Certain dental characteristics of Down syndrome (DS) make these children firm candidates for orthodontic intervention. There is little literature available on orthodontic treatment in patients with DS, particularly with regard to the use of fixed appliances. This case-control study shows that it is possible to perform orthodontic treatment with fixed appliances in adequately selected patients with DS. However, in patients with DS orthodontic treatment may take longer than usual and the frequency of complications is higher than in the general population.

The objective of this prospective, randomized, controlled trial, conducted from May 2002 to December 2007, was to compare post-operative anastomotic leakage and stricture formation following layered manual versus stapler oesophagogastric anastomosis in patients who underwent resection of oesophageal or gastric cardia carcinoma. Patients (n = 516) were randomized to receive either layered manual or circular stapled oesophagogastric anastomosis. Mean follow-up time was > 12 months. Anastomotic leakage occurred in one (0.4%) patient in the layered group and six (2.2%) in the stapler group; no statistically significant between-group difference. After operation, two (0.8%) patients in the layered group and 13 (5.0%) in the stapler group developed a benign oesophageal stricture; the difference between the groups was statistically significant. Compared with stapler anastomosis, layered manual anastomosis may significantly reduce the incidence of anastomotic strictures. This method is easy to apply and could be used as an alternative procedure for oesophagogastric anastomosis after resection for oesophageal or cardia carcinoma.

Scapular dyskinesis in pitchers can potentially lead to impairments in the optimal performance of muscles of the shoulder complex. The purpose of this prospective study was to evaluate whether the use of a scapula stabilizing t-shirt can decrease stress and discomfort in over-head baseball pitchers. Thirty-two semi-professional baseball pitchers were divided into 2 groups. Group A dressed the scapula stabilizing t-shirt during the weekly practice while group B (control group) continued to follow their training program without the t-shirt. All pitchers underwent a clinical examination at the beginning of the study (T0), 4 weeks (T1) and 8 weeks after (T2). Data collected showed a better clinical outcome at T1 which increased in T2 for pitchers in Group A, while in Group B athletes these positive results were not observed. This study underlines that scapula-stabilizing t-shirt can have positive effects on shoulder discomfort in over-head athletes.

To determine whether children who underwent surgery for congenital heart disease (CHD) are as fit as their peers. We studied 66 children (6-14 years) who underwent surgery for ventricular septal defect (n = 19), coarctation of aorta (n = 10), tetralogy of Fallot (n = 15), and transposition of great arteries (n = 22); and 520 healthy children (6-12 years). All children performed physical fitness tests: cardiorespiratory fitness, muscular strength, balance, flexibility, and speed. Metabolic score was assessed through z-score standardization using 4 components: waist circumference, blood pressure, blood lipids, and insulin resistance. Assessment also included self-reported and accelerometer-measured physical activity. Linear regression analyses with group (CHD vs control) as a predictor were adjusted for age, body mass index, physical activity, and parental education. Measured physical activity level, body mass index, cardiorespiratory fitness, flexibility, and total metabolic score did not differ between children with CHD and controls, whereas reported physical activity was greater in the CHD group than control group. Boys with CHD were less strong in upper muscular strength, speed, and balance, whereas girls with CHD were better in lower muscular strength and worse in balance. High-density lipoprotein was greater in boys and girls with CHD, whereas boys with CHD showed unhealthier glucose homeostasis. Appropriate physical fitness was achieved in children after surgery for CHD, especially in girls. Consequently, children with CHD were not at increased total metabolic risk. Lifestyle counseling should be part of every patient interaction. Copyright © 2017 Elsevier Inc. All rights reserved.

To test the local delivery of sirolimus nanoparticles following percutaneous transluminal coronary angioplasty (PTCA) to treat in-stent restenosis (ISR) in a swine model. Coronary bare-metal stent (BMS) implantation reduces major adverse cardiac events when compared with PTCA; however, ISR rates remain high. Eighteen swine underwent BMS deployment guided by intravascular ultrasound (IVUS). Of these, 16 developed ISR (1 stent/swine) and underwent angioplasty with a noncompliant balloon (PTCA-NC). The animals were then randomized into four groups for local infusion of sirolimus nanoparticles through a porous balloon catheter, as follows: (1) PTCA-NC alone (control); (2) PTCA-NC + (polylactic acid)-based nanoparticle formulation (anionic 1); (3) PTCA-NC + (polylactic-co-glycolic acid)-based nanoparticle formulation (anionic 2); and (4) PTCA-NC + Eudragit RS nanoparticle formulation (cationic). Coronary angiography and IVUS follow-up were performed 28 days after ISR treatment. There was one episode of acute coronary occlusion with the cationic formulation. Late area loss was similar in all groups at 28 days according to IVUS. However, luminal volume loss (control = 20.7%, anionic 1 = 4.0%, anionic 2 = 6.7%, cationic = 9.6%; P = 0.01) and neointimal volume gain (control = 68.7%, anionic 1 = 17.4%, anionic 2 = 29.5%, cationic = 31.2%; P = 0.019) were significantly reduced in all treatment groups, especially in anionic 1. PTCA-NC followed by local infusion of sirolimus nanoparticles was safe and efficacious to reduce neointima in this model, and this strategy may be a promising treatment for BMS ISR. Further studies are required to validate this method in humans. Copyright © 2012 Wiley Periodicals, Inc.

This study was aimed at evaluating the effect of two levels of intervention on the antibiotic prescribing in patients with common cold. Before and after audit-based study carried out in primary healthcare centres in Spain. General practitioners registered all the episodes of common cold during 15 working days in January and February in 2008 (preintervention). Two types of intervention were considered: full intervention, consisting in individual feedback based on results from the first registry, courses in rational antibiotic prescribing, guidelines, patient information leaflets, workshops on rapid tests -rapid antigen detection and C-reactive protein tests- and provision of these tests in the surgeries; and partial intervention, consisting of all the above intervention except for the workshop and they did not have access to rapid tests. The same registry was repeated in 2009 (postintervention). In addition, new physicians filled out only the registry in 2009 (control group). 210 physicians underwent the full intervention, 71 the partial intervention and 59 were assigned to the control group. The 340 doctors prescribed antibiotics in 274 episodes of a total of 12,373 cases registered (2.2%).The greatest percentage of antibiotic prescription was found in the control group (4.6%). The partial intervention increased the antibiotic prescription percentage from 1.1% to 2.7% while only doctors who underwent the complete intervention lead to a significant reduction of antibiotics prescribed, from 2.9% before to 0.7% after the intervention (p<0.001). Only physicians with access to rapid tests significantly reduced antibiotic prescription in patients with common cold.

The aim of this study is to investigate glucose uptake on FDG-PET in patients with chronic mental and cognitive symptoms following a single blunt mild traumatic brain injury (TBI) and without visible brain lesions on CT/MRI. Eighty-nine consecutive patients (mean age 43.8±10.75) who had a single blunt mild TBI from a traffic accident and suffering from chronic mental and cognitive symptoms without visible brain lesions on CT/MRI were enrolled in the study. Patients underwent FDG-PET imaging, and the mean interval between the TBI and FDG-PET was 50.0 months. The Wechsler Adult Intelligence Scale version III testing was performed within one month of the FDG-PET. A control group consisting of 93 healthy adult volunteers (mean age 42.2±14.3 years) also underwent FDG-PET. The glucose uptake pattern from FDG-PET in the patient group was compared to that from normal controls using statistical parametric mapping. Glucose uptake was significantly decreased in the bilateral prefrontal area and significantly increased around the limbic system in the patient group compared to normal controls. This topographical pattern of glucose uptake is different from that reported previously in patients with diffuse axonal injury (DAI), but may be similar to that seen in patients with major depression disorder. These results suggest that the pathological mechanism causing chronic mental and cognitive symptoms in patients with a single blunt mild TBI and without visible brain lesions might be different from that due to primary axonopathy in patients with DAI.

This study investigated the molecular changes of DKK-1, MMP13, Wnt-5a and \\upbeta -catenin after extracorporeal shockwave therapy (ESWT) in anterior cruciate ligament transected (ACLT) osteoarthritic (OA) knee in rats. 27 male Spraque-Dawley rats were divided into three groups. Group I was the control one and received sham knee arthrotomy but no ACLT or ESWT. Group II underwent ACLT, but no ESWT. Group III underwent ACLT and received ESWT. The animals were killed at 12 weeks, and the harvested knee specimens were subjected to histopathological examination and immunohistochemical analysis. Radiographs of the knees were obtained at 0 and 12 weeks. At 12 weeks, radiographs of group II showed more arthritic changes with formation of osteochondral fragments, whereas very subtle arthritis was noted in groups I and III. In histopathological examination, group II showed a significant increase of Mankin score and a decrease of subchondral bone as compared to groups I and III. Group III showed a significant decrease of Mankin score and an increase of subchondral bone, with the data comparable to group I. In immunohistochemical analysis, group II showed significant increases of DKK-1 and MMP13 and decreases of Wnt-5a and \\upbeta -catenin in articular cartilage and subchondral bone as compared to groups I and III. Group III showed significant decreases of DKK-1 and MMP13 and increases of Wnt-5a and \\upbeta -catenin, with the data comparable to group I. In conclusion, the application of ESWT causes molecular changes that are consistent with the improvement in subchondral bone remodeling and chondroprotective effect in ACLT OA knees in rats.

To investigate the effects of controlled passive stretching and active movement training using a portable rehabilitation robot on stroke survivors with ankle and mobility impairment. Twenty-four patients at least 3 months post stroke were assigned to receive 6 week training using the portable robot in a research laboratory (robot group) or an instructed exercise program at home (control group). All patients underwent clinical and biomechanical evaluations in the laboratory at pre-evaluation, post-evaluation, and 6-week follow-up. Subjects in the robot group improved significantly more than that in the control group in reduction in spasticity measured by modified Ashworth scale, mobility by Stroke Rehabilitation Assessment of Movement (STREAM), the balance by Berg balance score, dorsiflexion passive range of motion, dorsiflexion strength, and load bearing on the affected limb during gait after 6-week training. Both groups improved in the STREAM, dorsiflexion active range of motion and dorsiflexor strength after the training, which were retained in the follow-up evaluation. Robot-assisted passive stretching and active movement training is effective in improving motor function and mobility post stroke.

Little evidence is available on complementary therapies for anxiety and pain relief after caesarean delivery. The purpose of this study was to evaluate the effects of foot massage post-operatively in patients after caesarean delivery. 70 patients were divided to the study or control group after cesarean delivery. Patients in the study group had foot massages for 20 min after surgery. All patients underwent heart rate variability analysis (HRV) and scored their anxiety; pain intensity was evaluated using an 11-point numerical rating scale (NRS). In the study group the HRV, as measured by the low frequency power (LF) value and the LF-to-high frequency power (LF/HF) ratio during Holter assessment, was significantly less after foot massage intervention, but was not changed in the control group. Moreover, the HF value significantly increased and the anxiety score significantly decreased after foot massage intervention, but not in the control group. The pain intensity score obtained 60 min after the massage was significantly lower in the study group than the control group, as were the vital signs (respiratory rate, and systolic and diastolic blood pressure). Post-operative massage intervention can reduce anxiety and pain in patients after caesarean delivery. © Georg Thieme Verlag KG Stuttgart · New York.

To determine whether intraperitoneal silymarin administration has favorable effects on the heart, lungs, kidney, and liver and on oxidative stress in a rat model of supraceliac aorta ischemia/reperfusion injury. Thirty male Wistar albino rats were divided equally into three groups: sham, control, and silymarin. The control and silymarin groups underwent supraceliac aortic occlusion for 45 min, followed by a 60 min period of reperfusion under terminal anesthesia. In the silymarin group, silymarin was administered intraperitoneally during ischemia at a dose of 200 mg/kg. Rats were euthanized using terminal anesthesia, and blood was collected from the inferior vena cava for total antioxidant capacity, total oxidative status, and oxidative stress index measurement. Lungs, heart, liver and kidney tissues were histologically examined. Ischemia/reperfusion injury significantly increased histopathological damage as well as the total oxidative status and oxidative stress index levels in the blood samples. The silymarin group incurred significantly lesser damage to the lungs, liver and kidneys than the control group, while no differences were observed in the myocardium. Furthermore, the silymarin group had significantly lower total oxidative status and oxidative stress index levels than the control group. Intraperitoneal administration of silymarin reduces oxidative stress and protects the liver, kidney, and lungs from acute supraceliac abdominal aorta ischemia/reperfusion injury in the rat model.

Chronic obstructive parotitis (COP) is a common disease of the parotid gland. A total of 104 patients with COP were identified and randomized into a treatment group (52 cases) and a control group (52 cases). All patients underwent sialography and salivary gland scintigraphy (SGS) examinations before surgery. The patients in the treatment group received chymotrypsin combined with gentamicin via interventional sialendoscopy to irrigate the duct, and the control group received gentamicin alone. All patients were asked to record their pain on a visual analogue scale (VAS) before treatment and at 1 week, 2 weeks, 1 month, 3 months, and 6 months after surgery. The VAS score for pain intensity was decreased at 1 week post-treatment in both groups (P<0.05). Compared to the control group, the VAS score was lower in the treatment group at 1 week, 2 weeks, and 1 month post-treatment (P<0.05). The 6-month postoperative SGS results showed improved uptake and excretion in both groups (P<0.05). The treatment group exhibited higher scores for postoperative SGS excretion than the control group (P<0.05). The administration of chymotrypsin combined with gentamicin by sialendoscopy is effective for the treatment of non-stone-related COP and specifically improves the excretion function of the parotid gland.

Historically, stage I rectal cancer was treated with total mesorectal excision. However, there has been growing use of local excision, with and without adjuvant therapy, to treat these early rectal cancers. Little is known about how patients and providers choose among the various treatment approaches. The purpose of this study was to identify patient roles, preferences, and expectations as they relate to treatment decision making for patients with stage I rectal cancer. This is a population-based study. The study included a geographically diverse population and health-system-based cohort. A total of 154 adults with newly diagnosed and surgically treated stage I rectal cancer between 2003 and 2005 were included. We compared patients by surgical treatment groups, including total mesorectal excision and local excision. Clinical, sociodemographic, and health-system factors were assessed for association with patient decision-making preferences and expectations. A total of 80% of patients who underwent total mesorectal excision versus 63% of patients who underwent local excision expected that surgery would be curative (p = 0.04). The total mesorectal excision group was less likely to report that radiation would cure their cancer compared with the local excision group (27% vs 63%; p = 0.004). When asked about their preferred role in decision making, 28% of patients who underwent total mesorectal excision preferred patient-controlled decision making compared with 48% of patients who underwent local excision (p = 0.046). However, with regard to the treatment actually received, 38% of the total mesorectal excision group reported making their own surgical decision compared with 25% of the local excision group (p = 0.18). The study was limited by its sample size. The preferred decision-making role for patients did not match the actual decision-making process. Future efforts should focus on bridging the gap between the decision-making process and patient preferences regarding various treatment approaches. This will be particularly important as newer innovative procedures play a more prominent role in the rectal cancer treatment paradigm.

Corifollitropin alfa is a good choice for assisted reproductive technology (ART) cycles because fewer injections are needed than with other agents. In this retrospective cohort, we analyzed luteal injected half-dose depot gonadotropin hormone-releasing hormone (GnRH) agonist cycles in women who received corifollitropin alfa and those who underwent a conventional corifollitropin alfa cycle with a GnRH antagonist. In this retrospective cohort, we analyzed luteal injected half-dose depot GnRH agonist cycles in women who received corifollitropin alfa and those who underwent a conventional corifollitropin alfa cycle with a GnRH antagonist at the Division of Reproductive Endocrinology and IVF Unit, Obstetrics and Gynecology Department, Başkent University School of Medicine, Adana, Turkey, from March 2014 to August 2015. The patient's baseline characteristics were similar between the two groups. Forty-five patients underwent the long protocol, in which a half-dose of depot GnRH agonist was administered on day 21 of the preceding cycle. Forty-nine patients underwent the GnRH-antagonist protocol. Corifollitropin alfa was administered on the menstrual cycle day 3. The mean ages of the two groups were similar (32.77±5.55 vs. 34.2±4.51 years ["for the long- and antagonist-protocol groups, respectively"]). The total number of retrieved oocytes, the fertilization rate, and the number of transferred embryos were similar between the two groups. The only significant difference between the two protocols was the number of injections during the controlled ovarian stimulation (COH) cycle, which included the depot-agonist injection in the long-protocol group (4.46±1.64 vs. 5.71±2.51, p=0.006). The clinical pregnancy and implantation rates were similar in the two protocols (16/45 [35.6%] vs. 16/49 [32.7%] for the intention to treat and 32.5±6.82% vs. 36.25±8.58%, respectively). Our results show that ART cycles could be performed with fewer injections using corifollitropin alfa and a half-dose of depot GnRH agonist.

In recent years, there has been a dramatic rise in the annual number of ulnar collateral ligament (UCL) reconstructions performed in amateur baseball pitchers. Accordingly, increasing numbers of players are entering professional baseball having already undergone the procedure; however, the effect of prior UCL reconstruction on future success remains unknown. (1) To provide an epidemiologic report on baseball players who undergo UCL reconstruction before being selected in the Major League Baseball (MLB) Draft, (2) to define the outcomes in terms of statistical performance, and (3) to compare these results with those of matched controls (ie, non-UCL reconstruction). Cohort study; Level of evidence, 3. The MLB Amateur Draft Database was queried to identify all drafted pitchers who underwent UCL reconstruction before being drafted. For each pitcher drafted from 2005 to 2014 with prior UCL reconstruction, 3 healthy controls with no history of elbow surgery were randomly identified for matched analysis. A number of demographic and performance comparisons were made between these groups. A total of 345 pitchers met inclusion criteria. The annual number of pitchers undergoing predraft UCL reconstructions rose steadily from 2005 to 2016 ( P < .001). For matched control analysis, 252 pitchers with a UCL reconstruction and a minimum 2-year follow-up (drafted between 2005 and 2014) were matched to 756 controls (non-UCL reconstruction). As compared with the non-UCL reconstruction group, pitchers who underwent predraft UCL reconstruction reached the MLB level with greater frequency (20% vs 12%, P = .003), and their MLB statistical performances were similar for all measures. Compared with all other pitchers drafted during that period, players who had a predraft UCL reconstruction demonstrated an increased likelihood of reaching progressive levels of play (Full Season A, AA, and MLB) within a given time frame ( P < .05 for all). The number of UCL reconstructions performed in amateur baseball players before the draft increased year over year for the entire study period. Professional pitchers who underwent UCL reconstruction as amateurs appear to perform at least as well as, if not better than, matched controls without elbow surgery.

To evaluate the pain relieving effect of intervention with "Lamaze method of colonoscopy" in the process of colonoscopy. Five hundred and eighty-five patients underwent colonoscopy were randomly divided into three groups, Lamaze group, anesthetic group and control group. Two hundred and twenty-four patients of Lamaze group, the "Lamaze method of colonoscopy" were practiced in the process of colonoscopy. The Lamaze method of colonoscopy is modified from the Lamaze method of childbirth, which helped patients to relieve pain through effective breathing control. One hundred and seventy-eight patients in anesthetic group accepted sedation colonoscopy. For 183 patients in control group, colonoscopy was performed without any intervention. The satisfactory of colon cleaning, intestinal lesions, intubation time, success ratio, pain grading and complications were recorded. All data were statistically analyzed. There were no significant differences at base line of the three groups (P > 0.05). Anesthetic group shows advantage in intubation time than the other two groups (P < 0.05). Lamaze group shows no advantage in intubation time than that in control group (P > 0.05). The anesthetic group showed an apparent advantage in relieving pain (P < 0.01). Therefore, the "Lamaze method of colonoscopy" performed in colonoscopy could relieve pain effectively comparing with control group (P < 0.05). The patients in anesthetic group had the highest incidence of complications (P < 0.05). The performance of the "Lamaze method of colonoscopy" in the process of colonoscopy could relieve patients' pain, minimize the incidence of complications, and is worthy promotion in clinical practice.

Studies have shown that measures of gait variability are associated with falling in older adults. However, few studies have measured gait variability in people with Alzheimer disease, despite the high incidence of falls in Alzheimer disease. The purpose of this study was to compare gait variability of community-dwelling older adults with Alzheimer disease and control subjects at various walking speeds. Ten subjects with mild-moderate Alzheimer disease and ten matched control subjects underwent gait analysis using an electronic walkway. Participants were required to walk at self-selected slow, preferred, and fast speeds. Stride length and step width variability were determined using the coefficient of variation. Results showed that stride length variability was significantly greater in the Alzheimer disease group compared with the control group at all speeds. In both groups, increases in walking speed were significantly correlated with decreases in stride length variability. Step width variability was significantly reduced in the Alzheimer disease group compared with the control group at slow speed only. In conclusion, there is an increase in stride length variability in Alzheimer disease at all walking speeds that may contribute to the increased incidence of falls in Alzheimer disease.

Conventional cardiopulmonary bypass is the most commonly used means of artificial circulation in cardiac surgery. However, it suffers from the effects of haemodilution and activation of inflammatory/coagulation cascades. Prime displacement (PD) can offset haemodilution and Mini-Extracorporeal Technology (MIECT) can offset both. So far, no study has compared all of these modalities together; hence, we compared the outcomes of these 3 modalities at our institution. This was a retrospective analysis of our cardiac surgical database. A total of 9626 patients underwent conventional bypass (CB), 3125 patients underwent a modification of CB, called PD, and 904 underwent MIECT. A 1:1 propensity-matching algorithm was employed using IBM SPSS 24 to match (i) 813 MIECT patients with 813 CB patients and (ii) 717 MIECT patients with 717 PD patients. The patients included coronary artery bypass grafting and valve surgery. MIECT had significantly (P < 0.05) longer bypass and cross-clamp times compared to CB and PD. MIECT had significantly higher rates of postoperative atrial fibrillation associated with it compared to CB. The mean red cell blood transfusion was significantly lower in the MIECT group compared to the CB group as was the mean platelet transfusion and fresh frozen plasma transfusion. The overall 5-year survival was higher in the MIECT group compared to the CB group (log-rank, P = 0.018). Between the MIECT and the PD groups, we found the incidence of renal failure and gastrointestinal complications to be significantly higher in the PD group compared to the MIECT group. MIECT has short-term advantages over CB and PD. However, due to the retrospective limitations of the study, including calendar time bias, a multicentre randomized controlled trial comparing all 3 modalities will be beneficial for the larger cardiac community. © The Author(s) 2018.

OBJECTIVE The authors compared the efficacy and safety of arthroplasty using the Prestige LP cervical disc with those of anterior cervical discectomy and fusion (ACDF) for the treatment of degenerative disc disease (DDD) at 2 adjacent levels. METHODS Patients from 30 investigational sites were randomized to 1 of 2 groups: investigational patients (209) underwent arthroplasty using a Prestige LP artificial disc, and control patients (188) underwent ACDF with a cortical ring allograft and anterior cervical plate. Patients were evaluated preoperatively, intraoperatively, and at 1.5, 3, 6, 12, and 24 months postoperatively. Efficacy and safety outcomes were measured according to the Neck Disability Index (NDI), Numeric Rating Scales for neck and arm pain, 36-Item Short-Form Health Survey (SF-36), gait abnormality, disc height, range of motion (investigational) or fusion (control), adverse events (AEs), additional surgeries, and neurological status. Treatment was considered an overall success when all 4 of the following criteria were met: 1) NDI score improvement of ≥ 15 points over the preoperative score, 2) maintenance or improvement in neurological status compared with preoperatively, 3) no serious AE caused by the implant or by the implant and surgical procedure, and 4) no additional surgery (supplemental fixation, revision, or nonelective implant removal). Independent statisticians performed Bayesian statistical analyses. RESULTS The 24-month rates of overall success were 81.4% for the investigational group and 69.4% for the control group. The posterior mean for overall success in the investigational group exceeded that in the control group by 0.112 (95% highest posterior density interval = 0.023 to 0.201) with a posterior probability of 1 for noninferiority and 0.993 for superiority, demonstrating the superiority of the investigational group for overall success. Noninferiority of the investigational group was demonstrated for all individual components of overall success and individual effectiveness end points, except for the SF-36 Mental Component Summary. The investigational group was superior to the control group for NDI success. The proportion of patients experiencing any AE was 93.3% (195/209) in the investigational group and 92.0% (173/188) in the control group, which were not statistically different. The rate of patients who reported any serious AE (Grade 3 or 4) was significantly higher in the control group (90 [47.9%] of 188) than in the investigational group (72 [34.4%] of 209) with a posterior probability of superiority of 0.996. Radiographic success was achieved in 51.0% (100/196) of the investigational patients (maintenance of motion without evidence of bridging bone) and 82.1% (119/145) of the control patients (fusion). At 24 months, heterotopic ossification was identified in 27.8% (55/198) of the superior levels and 36.4% (72/198) of the inferior levels of investigational patients. CONCLUSIONS Arthroplasty with the Prestige LP cervical disc is as effective and safe as ACDF for the treatment of cervical DDD at 2 contiguous levels and is an alternative treatment for intractable radiculopathy or myelopathy at 2 adjacent levels.

Patients with anxiety disorders often experience a relapse in symptoms after exposure therapy. Similarly, threat responses acquired during Pavlovian threat conditioning often return after extinction learning. Accordingly, there is a need for alternative methods to persistently reduce threat responding. Studies in rodents have suggested that exercising behavioral control over an aversive stimulus can persistently diminish threat responses, and that these effects are mediated by the amygdala, ventromedial prefrontal cortex, and striatum. In this fMRI study, we attempted to translate these findings to humans. Subjects first underwent threat conditioning. We then contrasted two forms of safety learning: active avoidance, in which participants could prevent the shock through an action, and yoked extinction, with shock presentation matched to the active condition, but without instrumental control. The following day, we assessed subjects' threat responses (measured by skin conductance) to the conditioned stimuli without shock. Subjects next underwent threat conditioning with novel stimuli. Yoked extinction subjects showed an increase in conditioned response to stimuli from the previous day, but the active avoidance group did not. Additionally, active avoidance subjects showed reduced conditioned responding during novel threat conditioning, but the extinction group did not. We observed between-group differences in striatal BOLD responses to shock omission in Avoidance/Extinction. These findings suggest a differential role for the striatum in human active avoidance versus extinction learning, and indicate that active avoidance may be more effective than extinction in persistently diminishing threat responses. SIGNIFICANCE STATEMENT Extinguished threat responses often reemerge with time, highlighting the importance of identifying more enduring means of attenuation. We compared the effects of active avoidance learning and yoked extinction on threat responses in humans and contrasted the neural circuitry engaged by these two processes. Subjects who learned to prevent a shock through an action maintained low threat responses after safety learning and showed attenuated threat conditioning with novel stimuli, in contrast to those who underwent yoked extinction. The results suggest that experiences of active control over threat engage the striatum and promote a shift from expression of innate defensive responses toward more adaptive behavioral responses to threatening stimuli.

To evaluate the refractive outcomes of balanced salt solution infiltration during small-incision lenticule extraction (SMILE).This randomized prospective study enrolled 52 patients (104 eyes) with myopic astigmatism. Patients underwent SMILE to correct the myopic astigmatism in Daping Hospital of the Third Military Medical University between January and July 2013. One eye of each patient received traditional SMILE (control group) and the other received a modified SMILE procedure (liquid infiltration group). The corrected distance visual acuity (CDVA), postoperative uncorrected distance visual acuity (UDVA), refraction, wavefront aberration, intraocular pressure (IOP), modulation transfer function (MTF) cut-off frequency, and objective scattering index (OSI) were evaluated.UDVA in the liquid infiltration group was significantly higher than that in the control group at 1 day postoperatively, but not at 1 month after surgery. Moreover, OSI and MTF cut-off frequency in the liquid infiltration group were higher than those in the control group at early follow-up. However, no significant intergroup difference was observed in the OSI and MTF cut-off frequency at 3 months after surgery. In addition, the predictability was better in the liquid infiltration group than in the control group. The changes of horizontal coma in the liquid infiltration group were lesser than those in the control group. However, no intergroup difference was observed in the reduction of IOP at 1 month after surgery.The modified SMILE procedure results in better visual outcomes than did the traditional SMILE procedure when used for treating myopic astigmatism.

To evaluate effects of long-term administration of carprofen on healing of a tibial osteotomy in dogs. 12 healthy female Beagles. A mid-diaphyseal transverse osteotomy (stabilized with an intramedullary pin) of the right tibia was performed in each dog. The carprofen group (n = 6 dogs) received carprofen (2.2 mg/kg, PO, q 12 h) for 120 days; the control group (6) received no treatment. Bone healing and change in callus area were assessed radiographically over time. Dogs were euthanized 120 days after surgery, and tibiae were evaluated biomechanically and histologically. The osteotomy line was not evident in the control group on radiographs obtained 120 days after surgery. In contrast, the osteotomy line was still evident in the carprofen group. Callus area was significantly less in the carprofen group, compared with the area in the control group, at 20, 30, and 60 days after surgery. At 120 days after surgery, stiffness, elastic modulus, and flexural rigidity in the carprofen group were significantly lower than corresponding values in the control group. Furthermore, histologic evaluation revealed that the cartilage area within the callus in the carprofen group was significantly greater than that in the control group. Long-term administration of carprofen appeared to inhibit bone healing in dogs that underwent tibial osteotomy. We recommend caution for carprofen administration when treating fractures that have delays in healing associated with a reduction in osteogenesis as well as fractures associated with diseases that predispose animals to delays of osseous repair.

[Purpose] The aim of the study was to investigate the effect of kinesio tape on pain, range of motion, and disability of the shoulder. [Subjects and Methods] Seventy-four female patients who underwent modified radical mastectomy participated in this study. They were randomly divided into two groups, an experimental group that received kinesio tape for the shoulder joint in addition to a conventional physiotherapy program and a control group that received the physiotherapy program only. Outcome measures included the Visual Analogue Scale, shoulder range of motion, and Shoulder Pain and Disability Index. [Results] The experimental group showed significant differences in all outcome measures both within and between groups. The control group only showed a significant within group difference in shoulder flexion. [Conclusion] Clinicians should be able to recognize the benefits achieved through the use of adjunct treatment options such as kinesio tape in comparison with benefits that can be obtained through the use of individual modalities in physical therapy. Kinesio tape can be suggested and recommended for postmastectomy patients, especially for shoulder pain, range of motion, and disability. PMID:28174439

This study was carried out to investigate the influence of a propolis and tee tree oil-containing hygienic agent on selected oral health parameters, oral microflora, and the condition of periodontal health. Thirty-seven patients who underwent oral rehabilitation with a removable acrylic denture were selected and randomly assigned into two groups: study group (A) which received a newly formulated propolis and tee tree oil-containing toothpaste or a control group (C) without an active ingredient. API, S-OHI, and mSBI were assessed in three subsequent stages. During each examination swabs were employed for microbiological inoculation: in the study group after 4 weeks use of the active toothpaste showed a decrease in the number of isolated microorganisms. In the control group, after 4 weeks use of the toothpaste without active ingredients resulted in increase in the number of the isolated microorganisms. Improvements in hygiene and the condition of periodontium were observed in patients using active toothpastes. In the study group the oral flora diversity was reduced by the decrease in the number of cultured microorganism species, while in the control group an increase in the number of cultured microorganisms and their species was observed.

Background: To assess the effects of resistance training on circulating irisin concentration in older male adults, and to investigate the association between resistance training induced alteration of irisin and body fat. Methods: Seventeen older adults (mean age is 62.1 years old) were randomized into old control group (male, n = 7), and old training group (male, n = 10). The control group has no any exercise intervention. The resistance training group underwent leg muscle strength and core strength training program two times/wk, 55 min/class for 12 weeks. Before and after the intervention, we evaluated serum irisin level and body composition. Results: Serum irisin level was significantly increased in the resistance training group after the 12 weeks intervention period ( P < 0.01), but not in the control group. In the resistance training group, the reduction in whole-body fat percent was negatively correlated with the increase in serum irisin level ( r = -0.705, P < 0.05). Conclusion: After the 12 weeks intervention, circulating irisin levels were significantly elevated in the older adults. In summary, serum irisin may be involved in the regulation of body fat in older male adults.

Five types of porous Nickel-Titanium (NiTi) alloy samples of different porosities and pore sizes were fabricated. According to compressive and fracture strengths, three groups of porous NiTi alloy samples underwent further cytocompatibility experiments. Porous NiTi alloys exhibited a lower Young’s modulus (2.0 GPa ~ 0.8 GPa). Both compressive strength (108.8 MPa ~ 56.2 MPa) and fracture strength (64.6 MPa ~ 41.6 MPa) decreased gradually with increasing mean pore size (MPS). Cells grew and spread well on all porous NiTi alloy samples. Cells attached more strongly on control group and blank group than on all porous NiTi alloy samples (p < 0.05). Cell adhesion on porous NiTi alloys was correlated negatively to MPS (277.2 μm ~ 566.5 μm; p < 0.05). More cells proliferated on control group and blank group than on all porous NiTi alloy samples (p < 0.05). Cellular ALP activity on all porous NiTi alloy samples was higher than on control group and blank group (p < 0.05). The porous NiTi alloys with optimized pore size could be a potential orthopedic material. PMID:26047515

To determine if goserelin immediately after uterine artery embolization (UAE) affected myoma reduction. Randomized pilot study (level 1). Teaching hospital. Twenty-six women. All patients underwent UAE, and then 12 patients received 10.8 mg of goserelin 24 hours later. The treatment group was 5 years older: 43 versus 37.7 years. Uterine and myoma volumes were measured by ultrasound 2 weeks before UAE and at 3, 6, and 12 months. Uterine and fibroid volumes. Pretreatment uterine volume was 477 versus 556 cm3, and dominant fibroid volume was 257 versus 225 cm3 in the control versus goserelin groups. Analysis of variance measurements indicated that the change over time did not significantly differ between the two groups. By 12 months, the control group had a mean uterine volume reduction of 58%, while the goserelin group had a reduction of 45%. Dominant fibroid changes over time did not differ between the two groups. At 12 months, the mean fibroid volume had decreased by 86% and 58% in the control and goserelin groups, respectively. The addition of goserelin therapy to UAE did not alter the reduction rate or volume of uterine myomas.

To analyze the feasibility and efficacy of a novel system (Gamepad [GAMing Experience in PArkinson's Disease]) for biofeedback rehabilitation of balance and gait in Parkinson disease (PD). Randomized controlled trial. Clinical rehabilitation gym. Subjects with PD (N=42) were randomized into experimental and physiotherapy without biofeedback groups. Both groups underwent 20 sessions of training for balance and gait. The experimental group performed tailored functional tasks using Gamepad. The system, based on wearable inertial sensors, provided users with real-time visual and acoustic feedback about their movement during the exercises. The physiotherapy group underwent individually structured physiotherapy without feedback. Assessments were performed by a blinded examiner preintervention, postintervention, and at 1-month follow-up. Primary outcomes were the Berg Balance Scale (BBS) and 10-m walk test (10MWT). Secondary outcomes included instrumental stabilometric indexes and the Tele-healthcare Satisfaction Questionnaire. Gamepad was well accepted by participants. Statistically significant between-group differences in BBS scores suggested better balance performances of the experimental group compared with the physiotherapy without biofeedback group both posttraining (experimental group-physiotherapy without biofeedback group: mean, 2.3±3.4 points; P=.047) and at follow-up (experimental group-physiotherapy without biofeedback group: mean, 2.7±3.3 points; P=.018). Posttraining stabilometric indexes showed that mediolateral body sway during upright stance was significantly reduced in the experimental group compared with the physiotherapy without biofeedback group (experimental group-physiotherapy without biofeedback group: -1.6±1.5mm; P=.003). No significant between-group differences were found in the other outcomes. Gamepad-based training was feasible and superior to physiotherapy without feedback in improving BBS performance and retaining it for 1 month. After training, 10MWT data were comparable between groups. Further development of the system is warranted to allow the autonomous use of Gamepad outside clinical settings, to enhance gait improvements, and to increase transfer of training effects to real-life contexts.

Fibromyalgia (FM) is a disease that causes widespread pain and increased sensitivity to pain because of a dysfunction in the central nervous system. This study investigated the effect of music combined with vibration on acupuncture points for the treatment of FM. A total of 120 patients with FM were allocated randomly to four groups (30 patients each). One group listened to a sequence of Bach's compositions. The second group was subjected to vibratory stimuli on a combination of acupuncture points on the skin. The third group (complete) underwent both procedures in a simultaneous and synchronized manner, with inclusion of binaural beats. The fourth group (control) received no stimulation. The participants underwent the experimental procedure during five sessions performed on alternate days. They were assessed by the Fibromyalgia Impact Questionnaire (FIQ) and the Health Assessment Questionnaire (HAQ) before the first session and after the last session (20 days). All groups showed a significant improvement in FIQ and HAQ scores at the evaluation after the intervention. The complete group exhibited the best result on both the FIQ and HAQ (p<0.001), and the improvement in HAQ score was significant (p<0.004). The results suggest that the placebo effect in FM may be substantial. However, comparison between groups revealed that the complete group had the greatest reduction in both FIQ and HAQ, with a significant improvement in HAQ, suggesting that the combined use of music and vibration exerts a greater effect on FM symptoms.

Prospective observational cohort study. To compare the outcomes of our new technique, distraction arthrodesis of C1-C2 facet joint with C2 root preservation (Study group), to those of conventional C1-C2 fusion with C2 root transection (Control group) for the management of intractable occipital neuralgia caused by C2 root compression. We are not aware of any report concerning C2 root decompression during C1-C2 fusion. Inclusion criteria were visual analogue scale (VAS) score for occipital neuralgia 7 or more; C2 root compression at the collapsed C1-C2 neural foramen; and follow-up 12 months or more. The Study group underwent surgery with our new technique including (1) C1-C2 facet joint distraction and bone block insertion while preserving the C2 root; and (2) use of C1 posterior arch screws instead of conventional lateral mass screws during C1-C2 segmental screw fixation. The Control group underwent C2 root transection with C1-C2 segmental screw fixation and fusion. We compared the prospectively collected outcomes data. There were 15 patients in the Study group and 8 in the Control group. Although there was no significant difference in the VAS score for the occipital neuralgia between the 2 groups preoperatively (8.2 ± 0.9 vs. 7.9 ± 0.6, P = 0.39), it was significantly lower in the Study group at 1, 3, and 6 months postoperatively (P < 0.01, respectively). At 12 months, it was 0.4 ± 0.6 versus 2.5 ± 2.6 (P = 0.01). There was no significant difference in improvement in the VAS score for neck pain and neck disability index and Japanese Orthopedic Association recovery rate, which are minimally influenced by occipital neuralgia. Our novel technique of distraction arthrodesis with C2 root preservation can be an effective option for the management of intractable occipital neuralgia caused by C2 root compression.

To investigate the effects of a 5% NovaMin containing dentifrice on dentine tubule patency and surface roughness at 100g and 400g tooth brush abrasion forces. 75 polished human dentine samples were prepared and randomly allocated into one of five groups; control (1), Na 2 PFO 3 100g abrasion force (2), NovaMin 100g (3), Na 2 PFO 3 400g (4) and NovaMin 400g (5). The control group underwent two 2-min cycles of artificial saliva (AS), one 2-min erosion cycle; the rest underwent two toothbrush abrasion cycles in an AS/dentifrice slurry and one 2-min erosion cycle. All samples were imaged at baseline and post intervention using Tandem Scanning Microscopy and Profilometry to analyse tubule patency and roughness. Mean tubule patency increased significantly between baseline and post intervention in groups 1,2 and 4 and decreased significantly post intervention in groups 3 and 5 (p<0.01). Post intervention, there were statistically significant differences in mean patent tubules between NovaMin and the Na 2 PFO 3 and control groups (p<0.001). Surface roughness increased for all groups between baseline and post interventions (P<0.001); mean (SD) roughness increases for groups 1, 2, 3, 4 and 5 were 0.14 (0.05) μm, 0.18 (0.04) μm, 0.16 (0.06) μm, 0.19 (0.07) μm and 0.21 (0.02) μm respectively. Differences between group 1 and 5 were significant (p<0.01). Brushing with NovaMin resulted in significant dentine tubule occlusion at 100g and 400g, but brushing with Na 2 PFO 3 resulted in increased tubule patency. Surface roughness increased significantly at 400g brushing with NovaMin. There was no correlation between tubule patency and surface roughness. A NovaMin desensitising dentifrice resulted in tubule occlusion even at high brushing forces. There was minimal increase in surface roughness at the lower (100g) brushing force.

This study was performed to determine whether teens have different rates of posttonsillectomy hemorrhage, admission for dehydration, or recurrent tonsillitis compared to adults. Specifically, these parameters were compared within two groups: patients who underwent powered intracapsular tonsillectomy (PIT) and those who underwent monopolar electrocautery tonsillectomy (MET). In a retrospective review of 579 patients at least 12 years of age from January 2000 to July 2006 in a tertiary referral center, outcome measures of reoperation for hemorrhage, readmission or emergency room visit for dehydration, and postoperative tonsillitis were compared for 200 patients 12 to 19 years of age and 379 patients more than 19 years of age. These outcome measures in teens were compared to those in adults who had tonsillectomy by the same technique (101 teens who underwent PIT compared to 117 adults who underwent PIT, and 99 teens who underwent MET compared to 262 adults who underwent MET). Outcome measures were also compared within the PIT and MET groups based on the indication for surgery (chronic tonsillitis, tonsillar hypertrophy, or both). In comparing teens to adults who underwent the same technique (PIT versus PIT, or MET versus MET), no statistically significant differences existed in the incidence of hemorrhage, dehydration, or postoperative tonsillitis. Greater hemorrhage rates for adults who underwent MET compared to teens, however, almost met statistical significance (p = 0.053). Analyzing complication rates by indication within the PIT and MET groups exclusively revealed higher rates of hemorrhage in adults who underwent the MET technique for the indication of chronic tonsillitis. Within the PIT comparison, no significant differences were found on the basis of indication for surgery. Teenage patients who undergo tonsillectomy should be considered unique as far as complication rates are concerned. Comparison of technique-specific complication rates between adults and teens showed no significant differences in either the PIT or MET groups, although adults who underwent MET had greater hemorrhage rates that almost met significance (p = 0.053). Adults who were undergoing tonsillectomy for chronic tonsillitis were more likely than teens to encounter postoperative hemorrhage if they underwent the MET technique.

Objective: To explore the characteristics of electrocardiogram(ECG) and target potential features of premature ventricular contraction (PVC) in patients with complete left/right bundle branch block (CL/RBBB) and compare with those without CL/RBBB. Methods: A retrospective analysis was done in 8 outflow tract PVC patients with CL/RBBB, who successfully underwent radiofrequency ablation from August 2009 to June 2017. According to the bundle branch block chamber, patients were divided into the complete right bundle branch block (CRBBB) group ( n= 4) and the complete left bundle branch block (CLBBB) group ( n= 4). The control group were those who successfully underwent ablation at the same position as the above two groups but without CL/RBBB. The characteristics of ECG and target potential features were compared among groups. Results: One case in the CRBBB group was successfully ablated in the great cardiac vein with precordial R/S>1 transition at V(1) and one case in the CLBBB group was successfully ablated in the right coronary cusp with precordial R/S>1 transition at V(2), while other 6 cases were all with precordial R/S>1 transition at lead V(4). Precordial R/S>1 transition was not later than sinus rhythm (SR) in the CLBBB group. No statistical difference was found in the QRS complex duration between SR and PVC in the CL/RBBB patients [(134.38±23.80)ms vs (156.75±25.93)ms, P> 0.05], while statistical difference was shown in the control group [(92.63±5.76)ms vs (140.25±15.97)ms, P< 0.05]. Conclusion: Bundle branch block can lead to misjudgment of PVC origin with CL/RBBB during sinus rhythm, thus the origin chamber of the PVC should be determined according to the mapping and ablation result.

Objective: To establish a canine model of slow transit constipation (STC), and to test the changes in defecation, gastrointestinal transit time and pathology sections. Methods: Baseline information was measured in 8 beagle dogs, and these dogs were randomly divided into the control group and the model group. The dogs in model group were given a diet of canned meat, as well as a combination of compound diphenoxylate and alosetron hydrochloride for 5 weeks. Dogs in control group were given normal diet with no special intervention. Stool frequency and consistency were observed and recorded daily, and the gastrointestinal transit time (GITT) were measured every week. All animals underwent the midline laparotomy and the colonic tissues were taken from the rectosigmoid colon, then investigated by light microscopy, electron microscopy, and immunohistochemistry to evaluate changes of protein gene product 9.5(PGP9.5), synaptophysin and c-kit between two groups. Results: 8 beagle dogs underwent all experiment items successfully.Both of the stool frequency and scores of stool consistency decreased in model group( F =6.568, P =0.043; F =25.954, P =0.002). GITT delayed in model group( F =42.573, P =0.001). After 5 weeks of intervention, in the model group, the myenteric neurons and interstitial cells of Cajal showed damage such as swelling of mitochondria under electron microscopy, and both of the PGP9.5 and synaptophysin integrated option density of rectosigmoid colon were decreased ( t =3.471, P =0.013; t =2.506, P =0.046)under immunohistochemistry. The c-kit integrated option density showed no statistically significant differences between two groups( t =1.709, P =0.138). Conclusions: The canine model of STC which was consistent with clinical symptoms and pathological changes was successfully established, and it can be used to observe and evaluate the therapeutic effect of electrical stimulation, surgery and so on.

The aim of this study was to assess the impact of extraction of third molars on the occurrence of temporo-mandibular disorders (TMD). A review of the literature and a case-control study have been conducted. The case-control study compares the frequency of extraction of third molars between the sample with TMD (case) and the sample without TMD (control). The proportion of patients who had undergone extractions of wisdom teeth was higher in the case group than in the control group. The difference was statistically significant when patients had undergone extraction of all four wisdom teeth or when the extraction of four wisdom teeth underwent in one sitting or under general anesthesia. The study of patients in case sample shows that all signs of TMD were more common in patients who had undergone extractions in several sessions and under local anesthesia. The temporomandibular joint sounds are significantly more frequent with local anesthesia. In the case group, 85 to 92% of patients have parafunctions and 5 to 11% have malocclusion. This demonstrates the multifactorial etiology of temporomandibular disorders. © EDP Sciences, SFODF, 2015.

Research conducted with adults suggests that successful weight losers demonstrate greater activation in brain regions associated with executive control in response to viewing high-energy foods. No previous studies have examined these associations in adolescents. Functional neuroimaging was used to assess brain response to food images among groups of overweight (OW), normal-weight (NW), and successful weight-losing (SWL) adolescents. Eleven SWL, 12 NW, and 11 OW participants underwent functional magnetic resonance imaging while viewing images of high- and low-energy foods. When viewing high-energy food images, SWLs demonstrated greater activation in the dorsolateral prefrontal cortex (DLPFC) compared with OW and NW controls. Compared with NW and SWL groups, OW individuals demonstrated greater activation in the ventral striatum and anterior cingulate in response to food images. Adolescent SWLs demonstrated greater neural activation in the DLPFC compared with OW/NW controls when viewing high-energy food stimuli, which may indicate enhanced executive control. OW individuals' brain responses to food stimuli may indicate greater reward incentive processes than either SWL or NW groups. © 2015 The Obesity Society.

To analyze the control of intraocular pressure (IOP) with an Ahmed glaucoma drainage device (AGDD) in two groups of glaucoma patients--one with cicatricial ocular surface disease (COSD) and one with aniridia. This is a retrospective comparative case series of nine patients (11 eyes) with COSD and six patients (8 eyes) with aniridia who underwent AGDD surgery to control IOP. The main outcome measure in both groups was stability of IOP between 6 and 21 mmHg. Mean IOP decreased significantly in both groups after AGDD surgery (29.6 ± 8.7 vs 14.7 ± 2.5, p = 0.008 in the COSD group; 26.3 ± 8.2 vs 15.3 ± 5.8, p = 0.008 in the aniridia group). Over a mean post-surgery follow-up of 37.1 months in the COSD group, we managed to control IOP in nine eyes; IOP control was successful in 87 % of eyes at 12 months and 58 % of eyes at 26 months. Over a mean post-surgery follow-up of 37.4 months in the aniridia group, we managed to control the IOP in seven eyes; IOP control was successful in 87 % of eyes at 12 months. AGDD surgery had no significant deleterious effect on visual acuity in either group. A severe complication occurred in one eye (1/8) in the aniridia group (lost vision due to retinal detachment) and in one eye (1/11) in the COSD group (tube exposure). AGDD surgery is effective in controlling IOP and has a low complication rate in COSD and aniridia patients; however, some of the complications are severe and prompt management is needed to prevent deleterious results.

Stimulating communication is an important workplace issue. We investigated the effects of a brief communication skills training (CST) program based on the principles of cognitive behavioral therapy (CBT). A randomized controlled trial was conducted on 206 white-collar workers. The intervention group underwent a 2-hour CST group training conducted by an occupational physician. The results of the intention-to-treat analysis using a mixed-effects model showed that there was a significant interaction between group and time observed for the item "thinking together to solve problems and issues" (P = 0.02). The effect size (Cohen d) was 0.35 (95% confidence interval, 0.07 to 0.62). The present study suggests that a brief CST based on the principles of CBT could improve the communication behavior of workers.

This study aims to study the efficacy of simultaneous endoscopic bladder neck incision (BNI) and primary endoscopic valve incision (PEVI) in patients with posterior urethral valves (PUV). Nine PUV patients underwent PEVI and BNI over a year. They were compared to nine comparable historical controls that had undergone only PEVI. Trends in renal function tests, urodynamics and changes in the upper urinary tracts were evaluated after 3 months during which no pharmacotherapy was given. The incidence of bladder dysfunction in the two groups was similar-55.5 % in case group and 66.6 % in control group. Hypocompliant, high-pressure bladder was the predominant cystometric finding in both groups. Three patients in the case group and two patients in the control group had high end infusion pressure (EIP) with poor compliance. Detrusor overactivity (DOA) was seen in 23.1 % patients in the case group as compared to 55.5 % patients in the control group (P = 0.3348). Five patients in both groups were later started on anticholinergics due to raised EIP, small capacity bladder and/or DOA. Although BNI should theoretically improve the outcome of PUV patients, the current pilot study failed to demonstrate any significant difference. A larger sample size and longer follow-up are required to prove or disprove its efficacy.

To investigate the current status of knowledge, attitude, and practice (KAP)on the prevention and control of occupational diseases in occupational groups in Jinzhou, China, and to evaluate the intervention effects of health education. Using the cluster random sampling method, 1000 workers who underwent occupational health examination in Jinzhou Center for Disease Control and Prevention from September 2014 to April 2015 were enrolled in this study. They were equally and randomly divided into intervention group and control group. The intervention group received health education for 6 months through bulletin board, promotion materials, expert lecture, Q&A session, and other relevant educational events. The questionnaire survey was performed before and after intervention. The control group received the questionnaire survey but not the health education. The overall awareness rate of prevention and control knowledge was 75.34% in 990 workers in Jinzhou, China. After the intervention, the intervention group had a significantly higher awareness rate of prevention and control knowledge than the control group (89.87%~98.86% vs 71.25%~80.82%, P<0.05); the intervention group had a significantly higher attitude accuracy for" whether occupational health examination is necessary or not" and " is willing to received the training on occupational health knowledge" than the control group(χ(2)=57.857, P<0.05; χ(2)=70.683, P<0.05); and the intervention group had a significantly higher rate of correct behavior for" whether help the business management personnel to carry out the prevention and control of occupational diseases or not" and"whether actively understand the occupational hazards of job" (χ(2)=102.186, P<0.05; χ(2)=91.159, P<0.05). Health education can significantly increase the awareness rate of prevention and control knowledge on occupational diseases in occupational groups in Jinzhou, China. However, the more structured and longterm comprehensive intervention is necessary for improving their attitude and behavior.

AIM: To evaluate the effect of muscovite in preventing small bowel injury induced by nonsteroidal anti-inflammatory drugs (NSAIDs). METHODS: We recruited and screened thirty-two healthy volunteers who were randomly allocated equally into two groups: an NSAID control group, who received 75 mg slow-release diclofenac, twice daily for 14 d; and an NSAID-muscovite group, who received 3 g of muscovite in addition to the 75 mg of slow-release diclofenac, twice daily for 14 d. For gastroprotection, both groups were administered 20 mg/d of the proton pump inhibitor omeprazole. All eligible subjects underwent video capsule endoscopy (CE) prior to and 14 d after treatment. RESULTS: Thirty subjects (NSAID-muscovite group, n =16; NSAID control group, n =14) finally completed the whole trail. At the baseline CE examination, no statistically significant differences between the two groups have been observed. However, after 14 d of drug treatment, a significant difference was observed in the percentage of subjects with mucosal breaks when comparing the NSAID-muscovite group with the NSAID control group. While 71.4% (10/14) of subjects in the NSAID control group had at least one mucosal break, co-administration of muscovite in the NSAID-muscovite group reduced the rate to 31.3% (5/16) (P = 0.028). Moreover, higher number of mucosal breaks was found in the NSAID control group vs that in the NSAID-muscovite group (P < 0.05). CONCLUSION: Muscovite co-therapy reduced the incidence of small intestinal injury after 14 d of diclofenac administration. PMID:25152605

Objectives. To evaluate whether combining mental practice with physical practice training enhances hand function in patients with stroke. Methods. 10 for treatment and 10 for control were recruited for this pre/posttraining matched case control study. In the treatment group, subjects underwent combining mental practice with physical practice for four weeks. In the control group, subjects only participated in physical practice. Change of hand function and the number of activated voxels of the contralateral somatosensory motor cortex (SMC) acquired by functional magnetic resonance imaging were measured. Results. After training, the Action Research Arm Test score increased by 12.65 for treatment and by 5.20 for control. There was a significant difference in the Action Research Arm Test score between the two groups (P = 0.04). The activated voxels number of the contralateral SMC increased in both groups, but the activated voxels number in the contralateral SMC and the improvement of hand function for treatment were greater than for control. In the treatment group, the number of activated voxels of the contralateral SMC was positively correlated with better hand function scores. Conclusions. Combining mental practice with physical practice may be a more effective treatment strategy than physical training alone for hand recovery in stroke patients. PMID:25435713

The aim of this study was to evaluate anatomic properties of the lens capsule and iris by anterior segment optical coherence tomography (AS-OCT) in patients with pseudoexfoliation (PEX). This prospective study included 62 eyes of 62 patients with PEX syndrome and 43 eyes of 43 age- and gender-matched controls. All subjects underwent full ophthalmologic examinations including AS-OCT. Pupillary diameter, midperipheral stromal iris thickness, central and temporal lens capsule thicknesses, and peripheral pseudoexfoliation material thickness on the anterior lens capsule surface were measured and recorded. Mean age was 66.8 ± 9.3 years in the PEX group and 65.5 ± 8.9 years in the control group (p = 0.44). The PEX group consisted of 62 patients: 38 men (61.3%) and 24 women (38.7%); the control group included 43 subjects: 25 men (58.1%) and 18 women (41.9%). Pupillary diameter after pharmacologic mydriasis was 21% smaller in the PEX group than controls. Mean midperipheral iris thickness was 36 ± 7.2 μm (7.8%) thinner in the PEX group than that of control group (p = 0.047). The central anterior capsule was a mean of 3.40 ± 0.51 μm (18%) thicker in the PEX group compared to the control group (p = 0.0001). The temporal anterior lens capsule was a mean of 0.17 ± 0.15 μm thicker in the PEX group compared to the control group (p = 0.81). With high-resolution OCT imaging, it has become possible to evaluate the anterior lens capsule without histologic examination and demonstrate that it is thicker than normal in PEX patients.

Assessing the coma status of patients with fulminant hepatic failure (FHF) is important for determining the reversibility of brain damage and for properly timing liver transplantation. The compressed spectral array (CSA) method is a frequency analysis technique that processes electroencephalogram signals by computer to facilitate on-line interpretation. This method has been used to monitor the consciousness levels of neurointensive care unit patients. In this study, we determined whether CSA could be used to assess the coma status of patients with FHF, and whether CSA provided information that was useful in deciding when to proceed with liver transplantation. CSA recording was carried out in 17 FHF patients with encephalopathy (coma grade III-IV) who underwent living-related liver transplantation between August 1997 and May 1999. Recording was performed with a Neuromonitor OEE-72044 (NIHON KOHDEN, Osaka, Japan) every 24 h before and after transplantation, until the patients regained consciousness. The CSAs of healthy controls were distributed almost equally between 0 and 16 Hz. The CSAs of FHF patients in hepatic coma were classified into three patterns. Eight of the 17 patients showed very prominent slow waves of about 2 Hz (group A), and seven patients showed strongly suppressed rapid waves between 8 and 16 Hz (group B). The remaining two patients showed CSA patterns that were similar to those of healthy controls, even though these patients were comatose (group C). Abnormal CSA patterns were observed in 15 of the 17 patients (88%). Group B patients seemed to have higher coma grades than did group A patients. Sixteen patients underwent liver transplantation, completely recovered from hepatic encephalopathy, and subsequently showed CSA patterns similar to those of healthy controls. One patient died without regaining consciousness. These results suggest that CSA is useful in assessing the coma status of FHF patients and in evaluating electrophysiological recovery from hepatic coma after liver transplantation.

Severe obstructive sleep apnea (OSA) is associated with increased QT corrected interval dispersion (QTcd) and continuous positive airway pressure (CPAP) is thought to improve this arrhythmogenic marker. The aim of the study was to determine the decrease of ratio of cardiovascular risk in patients with obstructive sleep apnea. The study included 65 patients with severe OSA who had an apnea-hypopnea index (AHI) score of >30. Each patient underwent 12-channel electrocardiogram (ECG) monitoring and polysomnography. Patients with an AHI score of <5 were used as the control group. The control group also underwent ECG monitoring and polysomnography testing. The QTcd levels of both groups were calculated. Three months after CPAP treatment, ECG recordings were obtained from the 65 patients with severe OSA again, and their QTcd values were calculated. There were 44 male and 21 female patients with severe OSA syndrome. The age, gender, body mass index, initial saturation, minimum saturation, average saturation, and desaturation index were determined in both groups. The QTc intervals of the OSA patients (62.48±16.29ms) were significantly higher (p=0.001) than those of the control group (29.72±6.30ms). There were statistically significant differences between the QTc values before and after the CPAP treatment, with pretreatment QTc intervals of 62.48±16.29ms and 3-month post-treatment values of 41.42±16.96ms (p=0.001). There was a positive and significant correlation between QTcd periods and the AHI and hypopnea index (HI) in OSA patients (p=0.001; r=0.71; p=0.001; r=0.679, respectively). CPAP treatment reduced the QTcd in patients with severe OSA. In addition, shortening the QTcd periods in patients with severe OSA may reduce their risk of arrhythmias and cardiovascular disease.

BACKGROUND Mast cells are present in the airways of patients who have severe asthma despite glucocorticoid treatment; these cells are associated with disease characteristics including poor quality of life and inadequate asthma control. Stem cell factor and its receptor, KIT, are central to mast-cell homeostasis. We conducted a proof-of-principle trial to evaluate the effect of imatinib, a KIT inhibitor, on airway hyper-responsiveness, a physiological marker of severe asthma, as well as on airway mast-cell numbers and activation in patients with severe asthma. METHODS We conducted a randomized, double-blind, placebo-controlled, 24-week trial of imatinib in patients with poorly controlled severe asthma who had airway hyperresponsiveness despite receiving maximal medical therapy. The primary end point was the change in airway hyperresponsiveness, measured as the concentration of methacholine required to decrease the forced expiratory volume in 1 second by 20% (PC20). Patients also underwent bronchoscopy. RESULTS Among the 62 patients who underwent randomization, imatinib treatment reduced airway hyperresponsiveness to a greater extent than did placebo. At 6 months, the methacholine PC20 increased by a mean (±SD) of 1.73±0.60 doubling doses in the imatinib group, as compared with 1.07±0.60 doubling doses in the placebo group (P = 0.048). Imatinib also reduced levels of serum tryptase, a marker of mast-cell activation, to a greater extent than did placebo (decrease of 2.02±2.32 vs. 0.56±1.39 ng per milliliter, P = 0.02). Airway mast-cell counts declined in both groups. Muscle cramps and hypophosphatemia were more common in the imatinib group than in the placebo group. CONCLUSIONS In patients with severe asthma, imatinib decreased airway hyperresponsiveness, mast-cell counts, and tryptase release. These results suggest that KIT-dependent processes and mast cells contribute to the pathobiologic basis of severe asthma.

[Purpose] The effectiveness of a smartphone pedometer application was compared with that of a traditional pedometer for improving the physical activity and weight status of community-dwelling older adults. [Subjects and Methods] This study had a nonequivalent pretest-posttest control group design. Ninety-seven older adults (mean age ± SD, 60.1 ± 5.5 years) joined the smartphone pedometer group and underwent a 2-week walking intervention based on a smartphone pedometer application. Fifty-four older adults (mean age ± SD, 65.3 ± 8.7 years) joined the traditional pedometer group and underwent a 2-week walking intervention based on a traditional pedometer. The participants’ physical activity was evaluated using the International Physical Activity Questionnaire–Short Form, and their weight status was quantified by calculating the body mass index. The daily pedometer count was also documented. [Results] No significant time, group, or time-by-group interaction effects were found for any of the outcome variables. However, trends of improvement in physical activity and body mass index were seen only in the smartphone pedometer group. [Conclusion] A smartphone pedometer application might be more favorable than a traditional pedometer in improving physical activity and body mass index in community-dwelling older adults. However, further experimental studies are necessary to confirm the results. PMID:27313391

Clinical outcomes of intravenous (IV) infusion of zoledronic acid (ZOL) for lumbar interbody fusion surgery (LIFS) remain unknown. We investigated the efficacy of IV ZOL on clinical outcome and bone fusion after LIFS. We retrospectively analyzed 64 patients with both degenerative lumbar spondylolisthesis and osteoporosis who underwent LIFS from January 2007 to April 2010. All patients were followed up for 2 y. Thirty-two were treated with an IV infusion of ZOL 3 d after surgery and a second injection 1 y later, and the other 32 patients did not receive ZOL. Preoperatively and every 3 mo postoperatively, oswestry disability index questionnaire and visual analog scale (VAS) scores for back and leg were compared. Preoperative and final postoperative follow-up to evaluate for subsequent compression fractures were also performed. Pedicle screw loosening, cage subsidence, and fusion rate were documented 2 y after surgery. At 2-y follow-up, a solid fusion was achieved in 75% of the ZOL group and only 56% of the control group. At final follow up, the incidence of final subsequent vertebral compression fractures (19% of the ZOL group and 51% of the control group, P = 0.006), pedicle screw loosening (18% of the ZOL group and 45% of the control group, P = 0.03), and cage subsidence >2 mm (28% of the ZOL group and only 54% of the control group, P = 0.04) were significantly lower in the ZOL group than in the control group. The ZOL group demonstrated improvement in VAS (for leg pain VAS, 2/10 for the ZOL group and 5/10 for the control group; for back pain VAS, 2/10 for the ZOL group and 6/10 for the control group) and oswestry disability index scores (7/25 for the ZOL group and 16/25 for the control group). ZOL treatment has beneficial effects on instrumented LIFS both radiographic and clinically. Thus, ZOL treatment can be recommended for osteoporosis patients undergoing LIFS.

This study investigated the protective effect of EGB761 on blood vessels of denervated gastrocnemius of rat and its possible mechanism. Fifteen male adult SD rats were randomly divided into three groups: normal control group (n=3), control group (n=6) and EGB761-treated group (n=6). The rats in the control and EGB761-treated group underwent a neurotomy to bilateral sciatic nerves. Then, they were administered EGB761 [100 mg/(kg·d)] and isovolumic normal saline, respectively by gavage everyday. No treatment was given to the rats in the normal control group. Gastrocnemius was harvested at 1 and 3 week(s) postoperatively in each group. Immunohistochemical method was used to detect the ratio of capillary/fiber (CFR) of denervated gastrocnemius and the expression of VEGF, fetal liver kinase -1(Flk-1) receptor and HSP70 in the vascular wall. The results showed that in the normal control group, VEGF, Flk-1 and HSP70 were expressed in the vessel wall of gastrocnemius, with Flk-1 expressed only in the endothelial cell of vessels. CFR in the EGB761-treated group was significantly higher than that in the control group at 1 week and 3 week(s) after neurotomy. The expression of VEGF and Flk-1 in the vessel wall of both control and EGB761-treated group was much lower than that in the normal control group, and the expression of these proteins in the EGB761-treated group was decreased as compared with that in the control group. The expression of HSP70 in the vessel wall of both control and EGB761-treated groups was enhanced when compared with that in the normal control group, and it was substantially augmented in the EGB761-treated group in comparison to the control group. It was concluded that EGB761 has a protective effect on blood vessels of denervated gastrocnemius, which is related to the increased HSP70 expression but not the expression of VEGF and its receptor Flk-1.

Patients with osteoporotic vertebral compression fracture (OVCF) have postural changes and increased risk of falling. The aim of this study is to compare balance characteristics between patients with OVCF and healthy control subjects. Patients with severe OVCF and control subjects underwent computerised dynamic posturography (CDP) in this case-control study. Forty-seven OVCF patients and 45 controls were recruited. Compared with the control group, the OVCF group had significantly decreased average stability; maximal stability under the `eye open with swayed support surface' (CDP subtest 4) and 'eye closed with swayed support surface' conditions (subtest 5); and decreased ankle strategy during subtests 4 and 5 and under the `swayed vision with swayed support surface' condition (subtest 6). The OVCF group fell more frequently during subtests 5 and 6 and had longer overall reaction time and longer reaction time when moving backward during the directional control test. OVCF patients had poorer static and dynamic balance performance compared with normal control. They had decreased postural stability and ankle strategy with increased fall frequency on a swayed surface; they also had longer reaction times overall and in the backward direction. Therefore, we suggest balance rehabilitation for patients with OVCF to prevent fall.

The efficacy of stenting for right-sided malignant colonic obstruction is unknown. This study aimed to evaluate the safety, feasibility, and clinical benefits of self-expandable metallic stent insertion for right-sided malignant colonic obstruction. Clinical data from patients who underwent right hemicolectomy for right colon cancer from January 2006 to July 2014 at three Korea University hospitals were retrospectively reviewed. A total of 39 patients who developed malignant obstruction in the right-sided colon were identified, and their data were analyzed. Stent insertion was attempted in 16 patients, and initial technical success was achieved in 14 patients (87.5 %). No stent-related immediate complications were reported. Complete relief from obstruction was achieved in all 14 patients. Twenty-five patients, including two patients who failed stenting, underwent emergency surgery. In the stent group, 93 % (13/14) of patients underwent elective laparoscopic surgery, and only one surgery was converted to an open procedure. All patients in the emergency group underwent emergency surgery within 24 h of admission. In the emergency group, only 12 % (3/25) of patients underwent laparoscopic surgery, with one surgery converted to an open procedure. All patients in both groups underwent either laparoscopy-assisted or open right/extended right hemicolectomy with primary anastomoses as the first operation. The operative times, retrieved lymph nodes, and pathologic stage did not differ between the two groups. Postoperative hospital stay (9.4 ± 3.4 days in the stent group vs. 12.4 ± 5.9 in the emergency group, p = 0.089) and time to resume oral food intake (3.2 ± 2.1 days in the stent group vs. 5.7 ± 3.4 in the emergency group, p = 0.019) were shorter in the stent group. And there were no significant differences in disease-free survival and overall survival between the two groups. Stent insertion appears to be safe and feasible in patients with right-sided colonic malignant obstruction. It facilitates minimally invasive surgery and may result in better short-term surgical outcomes.

In this study, the relationship between ovarian function and ovarian limited dose in radiotherapy was evaluated in young patients with cervical cancer who underwent ovarian transposition (Fig1B). Moreover, the novel ovarian dose limit for a better preservation of ovarian function in intensity-modulated radiation therapy (IMRT) was determined. We retrospectively analyzed data from 86 patients with cervical cancer who received radical hysterectomy and ovarian transposition from January 2013 to June 2015. In agreement with the National Comprehensive Cancer Network Guidelines (NCCN) for Cervical Cancer Version 2.2015, 65 patients with pathological high-risk factors were administered adjuvant radiotherapy-20 of them received three-dimensional conformal radiotherapy (Observation Group A), 24 patients received IMRT with no limitation on radiation dose to ovaries (Observation Group B), and 21 patients underwent IMRT with limited radiation dose(V 10 <20%) to ovaries (Observation Group C). Twenty-one patients without any predetermined high-risk factors did not received radiation therapy (Control Group D). Patients from all four groups were followed up, and sex hormone levels (E 2 , P, follicle-stimulating hormone [FSH], LH) before radiation, postradiation, 3 month, and 6 month after the radiation therapy were measured by electrochemiluminescence immunoassay. Subsequently, changes in sex hormone levels in all four groups of patients at various time points were analyzed. The levels of sexual hormones (E 2 , P, FSH, LH) before radiation, postradiation, 3 month, and 6 month after the radiation therapy in patients from all three observation groups were significantly lower than those in patients of the control group (P < 0.05). There was no statistically significant difference in the levels of sex hormones in patients of the control group at different time points (P > 0.05). Within each observation group, there was a statistically significant difference in the sex hormone levels in patients before the radiation and after the radiation (P < 0.05); however, when data from all three observation groups were compared, only the difference in the levels of FSH and LH between the patients from Group A and Group C was statistically significant (P < 0.05). The results of receiver-operating characteristic (ROC) curve analysis suggested that limiting ovarian radiation dose to V 7.5  < 26% in IMRT prevents the disruption of ovarian function (area under ROC curve was 0.740, confidence interval [CI] = 0.606-0.874). In young patients with cervical cancer who underwent radical hysterectomy and ovarian transposition without receiving adjuvant radiotherapy, ovarian endocrine function was well preserved. In patients who received any type of postoperative radiotherapy, ovarian function was affected, suggesting that the standard ovarian limited dose used in IMRT disrupted ovarian function. The results of the ROC curve analysis suggested that the new optimal dose limit of V 7.5  < 26% should be used in IMRT to preserve ovarian function (P = 0.003). © 2017 The Authors.

Use of nonsteroidal anti-inflammatory drugs (NSAIDs) should be avoided in bariatric surgery patients. If use of an NSAID is inevitable, a proton pump inhibitor (PPI) should also be used. To determine the effect of an, compared to care-as-usual, additional intervention to reduce NSAID use in patients who underwent bariatric surgery, and to determine the use of PPIs in patients who use NSAIDs after bariatric surgery. A randomized controlled intervention study in patients after bariatric surgery. Patients were randomized to an intervention or a control group. The intervention consisted of sending a letter to patients and their general practitioners on the risks of use of NSAIDs after bariatric surgery and the importance of avoiding NSAID use. The control group received care-as-usual. Dispensing data of NSAIDs and PPIs were collected from patients' pharmacies: from a period of 6 months before and from 3 until 9 months after the intervention. Two hundred forty-eight patients were included (intervention group: 124; control group: 124). The number of users of NSAIDs decreased from 22 to 18 % in the intervention group and increased from 20 to 21 % in the control group (NS). The use of a PPI with an NSAID rose from 52 to 55 % in the intervention group, and from 52 to 69 % in the control group (NS). Informing patients and their general practitioners by letter, in addition to care-as-usual, is not an effective intervention to reduce the use of NSAIDs after bariatric surgery (trial number NTR3665).

In patients with acute coronary syndrome (ACS) who underwent coronary arteries revascularization, violations of hemodynamics, metabolism and heart rate variability often develop in the postoperative period, therefore, the goal of the study was to establish the features of disturbances and the effectiveness of correction of left ventricular systolic and diastolic dysfunction and heart rate variability in stages of cardiorehabilitation in patients with acute coronary syndrome who underwent coronary arteries revascularization. The experimental group included 40 patients with ACS in the postoperative period who underwent balloon angioplasty and stenting of the coronary arteries (25 patients with ST-segment elevation ACS and 15 patients without ST-segment elevation ACS). The age of examined patients was 37 to 74 years, an average of 52.6±6.7 years. The control group consisted of 20 patients, comparable in age and clinico-laboratory manifestations of ACS, who underwent drug treatment with direct anticoagulants, double antiplatelet therapy, β-blockers, ACE inhibitors and statins. Clinical efficacy of cardiorespiratory process in patients of both groups was assessed by the dynamics of general clinical symptoms and parameters of natriuretic propeptide, systolic and diastolic function of the left ventricle and heart rate variability. In the initial state, clinical and laboratory-instrumental signs of myocardial ischemia disappear in patients with ACS undergoing surgical revascularization of the coronary arteries, but clinical and subclinical manifestations of heart failure were diagnosed. The use of the accelerated program of cardiac rehabilitation already during the first month of studies leads to a decreasement of the signs of systolic and diastolic dysfunction, the level of NT-proBNP and improve in the variability of the heart rhythm wich significantly improves the life quality of patients with ACS. To monitor the effectiveness and safety of cardiac rehabilitation in patients with ACS who underwent coronary arteries revascularization, in addition to the generally accepted methods (determination of heart rate, blood pressure, a 6-minute test), it is advisable to diagnose the subclinical stage of heart failure by determining the level of NT-proBNP, Doppler echocardiogram, parameters of the left ventricular systolic and diastolic function and heart rate variability.
