To investigate the safety and feasibility of laparoscopic extraperitoneal sigmoid colostomy. Thirty-six patients with low rectal cancer undergoing laproscopic abdominoperineal resection from July 2011 to July 2012 were prospectively enrolled in the study and randomly divided into extraperitoneal colostomy group(EPC, n=18) and internal peritoneal colostomy group(IPC, n=18). Follow-up period was 4-16 (median, 7) months and postoperative complications were compared between two groups. One case in EPC group was converted to IPC because of poor blood supply of the proximal sigmoid, who was eliminated from the subsequent analysis. Compared with the IPC group, the surgery time was longer in EPC group [(25.3±8.5) min vs. (14.7±6.4) min], while the difference was not statistically significant(P>0.05). Each group had 1 case of stoma ischemia, who both received the colostomy reconstructive surgery. The incidence of stoma edema was significantly higher in EPC group[35.3%(6/17) vs. 0, P<0.05). The early postoperative complications rate did not significantly different between the two groups[58.8%(10/17) vs. 27.8%(5/18), P>0.05]. The late postoperative complications rate was 22.2%(4/18) in IPC group, including 1 case of stoma prolapse, 1 case of stoma stenosis and 2 cases of parastomal hernia. No later postoperative complication occurred in EPC group. Extraperitoneal sigmoid colostomy is an easy and safe procedure with lower late complications as compared to internal peritoneal sigmoid colostomy.

Involvement of the digestive system in AIDS pathologies or injuries is frequent. Aiming at comparing the frequency, the importance that these lesions have for death and the survival time in patients using or not using HAART, we studied 322 necropsies classified as follows: Group A - without antiretroviral drugs (185 cases); B - one or two antiretroviral drugs or HAART for less than six months (83 cases); C - HAART for six months or longer (54 cases). In the overall analysis of the digestive system, changes were present in 73.6% of cases. The most frequent was Candida infection (22.7%), followed by cytomegalovirus (19.2%), Histoplasma capsulatum (6.5%), mycobacteria (5.6%), and Toxoplasma gondii (4.3%). T. gondii infection was more frequent in group A compared with group C, and cytomegalovirus (CMV) was more frequent in group A compared with groups B and C (p < 0.05); 2.2% of the deaths were due to gastrointestinal bleeding. Regarding the segments, only in the large intestine, and only cytomegalovirus, were more frequent in group A compared with group C. We conclude that digestive system infections are still frequent, even with the use of HAART. However, the average survival time in group C was more than three times greater than the one in group A and nearly double that of group B, demonstrating the clear benefit of this therapy.

To clarify the detection failure rate of chest radiography for the identification of nursing and healthcare-associated pneumonia (NHCAP), we compared high-resolution computed tomography (HRCT) with chest radiography simultaneously for patients with clinical symptoms and signs leading to a suspicion of NHCAP. We analyzed 208 NHCAP cases and compared them based on four groups defined using NHCAP criteria, patients who were: Group A) resident in an extended care facility or nursing home; Group B) discharged from a hospital within the preceding 90 days; Group C) receiving nursing care and had poor performance status; and Group D) receiving regular endovascular treatment. Chest radiography was inferior to HRCT for the identification of pneumonia (149 vs 208 cases, p < 0.0001). Among the designated NHCAP criteria, chest radiography identified pneumonia cases at a significantly lower frequency than HRCT in Group A (70 vs 97 cases, p = 0.0190) and Group C (86 vs 136 cases, p < 0.0001). The detection failure rate of chest radiography differed among NHCAP criteria; 27.8% in Group A, 26.5% in Group B, 36.7% in Group C and 5.8% in Group D. Cerebrovascular disease and poor functional status were significantly more frequent in patients in Groups A and C compared with those in Groups B and D. Physicians may underestimate pneumonia shadow in chest radiographs in patients with NHCAP, and the detection failure rate of chest radiography differed among NHCAP criteria. Poor functional status may correlate with the low accuracy of chest radiography in diagnosing pneumonia. Copyright © 2015. Published by Elsevier Ltd.

300 cases of non-melanoma cutaneous lesion procedures carried out by the Oral and Maxillofacial Surgery and Dermatology departments in a North West London hospital over a 6 month period between September 2011 and February 2012 were included in a retrospective case control study. The results from each speciality were compared. The mean age of the OMFS group was 75.8 years compared to 69.9 years in the dermatology group. There was no statistically significant difference in gender between the 2 groups. The OMFS group treated a higher proportion of atypical (17%) and malignant (64.9%) cases compared to the dermatology group (11.3% and 50.5% respectively). This could also account for the fact that the OMFS group carried out a higher number of full excisions compared to dermatology. Both groups had a similar number of false positives (a benign lesion initially diagnosed as malignant) and a similar proportion of false negatives (a malignant lesion initially diagnosed as benign). Overall, the results show that both specialities had similar outcomes when managing non-melanoma cutaneous lesions. Both groups adhere to the guidelines set out by the British Association of Dermatologists and the National Institute of Clinical Excellence when managing such lesions. Crown Copyright © 2014.

To observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia. Totally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups. Compared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05). Treatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.

Two groups of 20 patients undergoing day case vaginal termination of pregnancy received either methohexitone and alfentanil 7.5 micrograms/kg or methohexitone and fentanyl 1.5 micrograms/kg. Their recovery times and memory function at 1 and 2 hours after surgery were compared. No difference in the recovery of the 2 groups was noted but at 2 hours after operation the alfentanil group showed impairment of memory for new facts compared with pre-operative memory function testing. This was not evident in the fentanyl group. Apart from this finding alfentanil was adjudged to be a suitable agent for day case anaesthesia.

Objective. To evaluate online case simulation vs a paper case on student confidence and engagement. Design. Students enrolled in a pharmacotherapy laboratory course completed a patient case scenario as a component of an osteoarthritis laboratory module. Two laboratory sections used a paper case (n=53); three sections used an online virtual case simulation (n=81). Student module performance was assessed through a submitted subjective objective assessment plan (SOAP) note. Students completed pre/post surveys to measure self-perceived confidence in providing medication management. The simulation group completed postmodule questions related to realism and engagement of the online virtual case simulation. Group assessments were performed using chi-square and Mann Whitney tests. Assessment. A significant increase in all 13 confidence items was seen in both student groups following completion of the laboratory module. The simulation group had an increased change of confidence compared to the paper group in assessing medication efficacy and documenting a thorough assessment. Comparing the online virtual simulation to a paper case, students agreed the learning experience increased interest, enjoyment, relevance, and realism. The simulation group performed better on the subjective SOAP note domain though no differences in total SOAP note scores was found between the two groups. Conclusion. Virtual case simulations result in increased student engagement and may lead to improved documentation performance in the subjective domain of SOAP notes. However, virtual patient cases may offer limited benefit over paper cases in improving overall student self-confidence to provide medication management. PMID:26941442

The association between ABO blood groups and intracranial aneurysms is not well-known. Many co-morbid factors are associated with intracranial aneurysms. Our objective was to assess the prevalence of different blood group in patients with intracranial aneurysm and to look for associations between risk factors and these groups. This retrospective study includes 1,491 cases who underwent surgical operations for intracranial aneurysms from 1993-2014. We have evaluated the information related to clinical history, ABO blood groups and associated risk factors in the patients both ruptured and unruptured intracranial aneurysms by chart review of the cases. In our study, out of 1,491 cases, the most common ABO blood groups were group O (668 cases, 44.80%) and Group A (603 cases, 40.44%), and Rh(+) in 1,319 (88.4%) and Rh(-) in 147 (11.6%). Blood Group A (43% vs. 36%) and Group B (16.2% vs. 8.6%) were significantly higher in Caucasian and African Americans respectively. However, in general population, there was no significant difference in blood groups between Caucasians and African Americans. Rh(-) factor was significantly higher in Caucasians compared to African Americans. Incidence of smoking was significantly higher in aneurysm patients with O group compared to others. In addition, incidence of hypercholesterolemia was significantly higher in aneurysm patients with A group compared to others. The racial disparity in the distribution of blood groups, and risk factor association with blood groups in the development of intracranial aneurysm needs to be considered. The findings from our study may be useful in identifying patients at increased risk. Further study may be required to establish the risks from multiple centers studies around the world.

The precise effect and the quality of different cases used in dermatology problem-based learning (PBL) curricula are yet unclear. To prospectively compare the impact of real patients, digital, paper PBL (PPBL) and traditional lecture-based learning (LBL) on academic results and student perceptions. A total of 120 students were randomly allocated into either real-patients PBL (RPBL) group studied via real-patient cases, digital PBL (DPBL) group studied via digital-form cases, PPBL group studied via paper-form cases, or conventional group who received didactic lectures. Academic results were assessed through review of written examination, objective structured clinical examination and student performance scores. A five-point Likert scale questionnaire was used to evaluate student perceptions. Compared to those receiving lectures only, all PBL participants had better results for written examination, clinical examination and overall performance. Students in RPBL group exhibited better overall performance than those in the other two PBL groups. Real-patient cases were more effective in helping develop students' self-directed learning skills, improving their confidence in future patient encounters and encouraging them to learn more about the discussed condition, compared to digital and paper cases. Both real patient and digital triggers are helpful in improving students' clinical problem-handling skills. However, real patients provide greater benefits to students.

The aim of this study was to retrospectively audit eight years' experience of an IVF surrogate gestational programme and to compare the outcome of surrogacy due to absence of the uterus with surrogacy indicated for repeated IVF failure and recurrent abortions. A total of 60 cycles of IVF surrogate pregnancy were initiated in 19 treated couples. Absence of the uterus was the indication for surrogacy in 10 cases: Rokitansky syndrome (eight cases) and post-hysterectomy (two cases) designated as group A. The indications in the remaining nine patients (group B) were: IVF implantation failure (three cases), habitual abortions (four cases) and deteriorating maternal diseases (two cases). IVF performance and subsequent pregnancy outcome of groups A and B were compared. There was no difference in ovarian stimulation parameters and in IVF performance between the groups A and B. The overall pregnancy rate per transfer was 10/60 (17%). The pregnancy rates per patient and per transfer were 7/10 (70%) and 7/35 (20%) in group A compared with 3/9 (33%) and 3/25 (12%) in group B. A median number of three treatment cycles were needed to achieve pregnancy. In conclusion, the existence or absence of the uterus in the commissioning mothers is irrelevant for their IVF performance and conception rates. In patients who conceived after more than three IVF cycles, an additional 'oocyte factor' might be present.

To compare clinical outcomes of cataract surgery in eyes with and without pseudoexfoliation (PXF). Retrospective deidentified data analysis. A total of 123 PXF and 4776 non-PXF eyes of patients who underwent cataract surgery. We compared data on visual acuity, Visual Function Questionnaire (VFQ)-based quality of life, and complications in PXF and non-PXF eyes from the Veterans Affairs (VA) Ophthalmic Surgery Outcomes Data Project across 5 VA medical centres. Pupillary expansion devices were used in 31 (25.2%) PXF cases and 398 (8.4%) non-PXF cases (p < 0.0001). Capsular tension rings were used in 6 (4.9%) PXF cases and 55 (1.2%) non-PXF cases (p < 0.004). The following complications occurred more frequently in PXF cases: zonular dehiscence without vitrectomy (4 [3.3%] PXF cases vs 40 [0.8%] non-PXF cases p = 0.02), persistent inflammation (28 [24.1%] vs 668 [14.5%]; p = 0.007), and persistent intraocular pressure elevation (5 [4.3%] vs 68 [1.5%]; p = 0.03). Best corrected visual acuity (BCVA) improved in both groups after 1 month, but 87 (83.7%) PXF cases achieved postoperative BCVA better than or equal to 20/40 compared to 3991 (93.8%) non-PXF cases (p = 0.0003). There was no significant difference in the postoperative composite VFQ scores between PXF (82.1 ± 16.9) and non-PXF cases (84.2 ± 16.8, p = 0.09). Several complications occurred more frequently in the PXF group compared to the non-PXF group, and fewer PXF cases achieved BCVA better than or equal to 20/40. Despite this, both groups experienced similar improvement in vision-related quality of life after cataract surgery. Published by Elsevier Inc.

To compare the clinical efficacy of grade III, IV supination-eversion fractures-dislocations of ankle joint between manipulative treatment and operative treatment. From September 2007 to December 2008, the clinical data of 60 patients with grade III, IV supination-eversion fractures-dislocations of ankle joint were retrospectively analyzed. There were 32 males and 28 females, ranging in age from 18 to 70 years with an average age of 38.17 years. All patients were respectively treated with manipulative treatment (conservative group, 30 cases) and operative treatment (operative group, 30 cases). The joint function was compared with Mazur standard; the reduction and shifting of fractures were observed with X-ray; the hospitalization day and the therapeutic cost were compared between two groups. All patients were followed up with an average of 15.27 months (ranged, 6 to 25 months). In conservative group, 16 cases got excellent result in joint function, 10 good, 3 fair, 1 poor; in operative group, 20 cases got excellent result, 8 good, 2 fair, 0 poor. In conservative group in the X-ray showed 25 cases obtained excellent and good reduction, 4 fair, 1 poor; and in operative group in the X-ray showed 28 cases obtained excellent and good reduction, 2 fair, 0 poor. There was no significant difference at the joint function and X-ray film after treatment between two groups (P > 0.05). The hospital day was respectively (7.87 +/- 3.34), (17.37 +/- 4.64) d in conservative group and operative group; and the therapeutic cost was respectively (2 506.67 +/- 649.10), (11 473.33 +/- 1 564.90) yuan. There was significant difference at hospital day and therapeutic cost between two groups (P < 0.05). Conservative treatment and operative treatment can both reach a very good result in treating grade III, IV supination-eversion fractures and dislocations of ankle joint. However, conservative treatment has advantage of high safety factor, low therapeutic cost, can reduce medical costs for patients.

One hundred and two cases of Bell's palsy were randomized into an EA combined with herbal acupoint sticking group (group A, 50 cases) and an EA group (group B, 52 cases), EA at Cuanzhu (BL 2), Yangbai (GB 14), Taiyang (EX-HN 5), Quanliao (SI 18),Xiaguan (ST 7), Yingxiang (LI 20), etc. were applied in both groups and "facial paralys No.I " was applied at Yifeng (TE 17) in group A, once daily and 10 times totally were needed. The score of facial nerve function, clinical efficacy were compared before and after treatment. At 1 and 3 month follow up visit, the quality of life scale( WHOQOL-BREF) and the occurrence of complication were observed. The scores of facial nerve function in group A and group B were all significantly improved compared with those before treatment (48. 2+/- 2. 9 vs 25. 7 +/- 4. 9, 45. 9 +/- 6. 2 vs 25. 8 +/- 5. 5, both P0. 05). The occurrence of complication in group A (1 case) was significantly less than that in group B (8 cases, P 0. 05). Compared with EA, the combination of EA and acupoint sticking therapy for Bell's palsy cannot only improve the clinical efficacy and reduce the occurrence of complication but also reliable without any side effect.

To compare the efficacy differences between needle-knife therapy and acupuncture-cupping for treatment of cervical spondylosis (CS) of cervical type. Sixty cases of CS were randomly divided into a needle-knife group (30 cases) and an acupuncture-cupping group (30 cases). The needle-knife therapy was applied at points among superior nuchal line of occipital bone, bilateral neck muscle, neck centerline, trapezius and medial border scapula for only once. In the acupuncture-cupping group, acupuncture was applied at Fengchi (GB 20), Fengfu (GV 16), Tianzhu (BL 10), Dazhui (GV 14), Jianjing (GB 21), Jiaji (Ex-B2, from C4 to C6), Houxi (SI 3) and Ashi point, followed by cupping on local skin, once every other day for totally six times. The score of neck stiffness and visual analogue scale (VAS) were observed before and after treatment, in follow-up of 1, 3 and 6 months after treatment in the two groups, and the efficacy was compared. In the needle-knife group, 9 cases were cured, 12 cases were markedly effective, 8 cases were effective and 1 case was failed; the total effective rate was 96.7% (29/30) and the cured and markedly effective rate was 70.0% (21/30). In the acupuncture-cupping group, 8 cases were cured, 9 cases were markedly effective, 11 cases were effective and 2 cases were failed; the total effective rate was 93.3% (28/30) and the cured and markedly effective rate was 56.7% (17/30). The difference of total effective rate in the two groups was not statistically significant (P > 0.05), but the cured and markedly effective rate of needle-knife group was significantly superior to that of acupuncture-cupping group (P < 0.05). The needle-knife therapy was significantly superior to acupuncture-cupping on improvement of neck stiffness in the follow-up of 1, 3, 6 months after treatment (P < 0.05, P < 0.001); both treatments were effective on relief of neck pain, but the needle-knife group had better effects in the follow-up of 3 and 6 months after treatment compared with acupuncture-cupping group (both P < 0.01). The needle-knife therapy has better effects on neck stiffness and pain relief than acupuncture-cupping, and it is more treatment time saving.

Aim: The aim of this study was to identify the personality traits of alcohol and human immunodeficiency virus (HIV)-positive patients and to compare them with normal controls. Materials and Methods: This cross-sectional study included 100 consecutive patients with alcohol dependence and HIV each and a control group of 100 normal cases without any physical or psychiatric illness. A score of 2 or less on the General Health Questionnaire was taken as cutoff, and the participants were included in the study with written informed consent. All participants were assessed with the NEO personality inventory revised and sensation-seeking scale (SSS). Results: There were significant differences among the study group on all the five factors, i.e., neuroticism (N), extraversion (E), conscientiousness (C), openness to experience (O), and agreeableness (A). On factor “N,” HIV and alcohol group scored significantly more as compared to normal group. Odds ratio revealed high neuroticism to be a risk factor in alcohol-dependent and HIV cases (P < 0.05). The normal group scored significantly higher on factor “E” as compared to HIV and alcohol cases. High scores on factor “E” and “C” have a protective. Odds ratio found low score of factor “C” as a risk factor; however, “O” did not emerge as a risk factor. The logistic regression revealed that high scores on “N” and “E” and low “A” score had a significant association with alcohol dependence (P < 0.05). Among HIV cases, high score on “N” and “E” and low “C” score emerged significant. Alcohol cases scored significantly more on boredom susceptibility (BS) on SSS as compared to HIV and normal controls. On disinhibition (DIS), HIV cases and alcohol cases scored significantly higher as compared to normal group (P < 0.05). Conclusion: High “N” scores on NEO personality inventory are significantly associated with alcohol dependence and HIV while high scores on “E” and “C” have a protective effect. On SSS, HIV-positive cases are characterized by high DIS scores while alcohol dependence is associated with high scores on BS and DIS. PMID:28163408

To compare the effectiveness between minimally invasive plate osteosynthesis (MIPO) and open reduction and internal fixation (ORIF) for treatment of extra-articular distal tibial fracture. Between March 2009 and March 2012, 57 patients with extra-articular distal tibial fractures were treated, and the clinical data were retrospectively analyzed. Of 57 cases, 31 were treated with MIPO (MIPO group), and 26 with ORIF (ORIF group). There was no significant difference in gender, age, cause of injury, type of fractures, complication, and time from injury to operation between 2 groups (P > 0.05). The operation time, intraoperative blood loss, fracture healing time, and complications were compared between 2 groups. There was no significant difference in operation time and intraoperative blood loss between 2 groups (P > 0.05). Wound infection occurred in 5 cases [2 in MIPO group (6.5%) and 3 in ORIF group (11.5%)] showing no significant difference (Chi(2)=0.651, P=0.499). The other wound obtained healing by first intention. All cases were followed up 13-24 months (mean, 15 months). No significant difference was found in the average healing time between 2 groups and between patients with types A and B by AO classification (P > 0.05); in patients with type C, the healing time in MIPO group was significantly shorter than that in ORIF group (t= -2.277, P=0.033). Delayed union was observed in 3 cases of MIPO group (9.7%) and in 4 cases of ORIF group (15.4%), showing no significant difference (Chi(2)=0.428, P=0.691). Mal-union occurred in 4 cases of MIPO group (12.9%) and in 1 case of ORIF group (3.8%), showing no significant difference (Chi(2)=1.449, P=0.362). No significant difference was found in Mazur score between 2 groups (t=0.480, P=0.633). The excellent and good rate was 93.5% in MIPO group (excellent in 24 cases, good in 5 cases, fair in 1 case, and poor in 1 case) and was 92.3% in ORIF group (excellent in 18 cases, good in 6 cases, and poor in 2 cases), and the difference was not significant (Z= -0.687, P=0.492). Both MIPO and ORIF have good results in treating extra-articular distal tibial fractures. MIPO is superior to ORIF for treating complex and communited fractures.

To compare the clinical results of repairing bone defect of limbs with tissue engineering technique and with autogeneic iliac bone graft. From July 1999 to September 2001, 52 cases of bone fracture were randomly divided into two groups (group A and B). Open reduction and internal fixation were performed in all cases as routine operation technique. Autogeneic iliac bone was implanted in group A, while tissue engineered bone was implanted in group B. Routine postoperative treatment in orthopedic surgery was taken. The operation time, bleeding volume, wound healing and drainage volume were compared. The bone union was observed by the X-ray 1, 2, 3, and 5 months after operation. The sex, age and disease type had no obvious difference between groups A and B. all the wounds healed with first intention. The swelling degree of wound and drainage volume had no obvious difference. The operation time in group A was longer than that in group B (25 minutes on average) and bleeding volume in group A was larger than that in group B (150 ml on average). Bone union completed within 3 to 7 months in both groups. But there were 2 cases of delayed union in group A and 1 case in group B. Repair of bone defect with tissue engineered bone has as good clinical results as that with autogeneic iliac bone graft. In aspect of operation time and bleeding volume, tissue engineered bone graft is superior to autogeneic iliac bone.

To explore causes of shoulder pain and propose prevention measures in treating acromioclavicular joint dislocation. From January 2005 to January 2013, 86 patients with acromioclavicular joint dislocation (Tossy III) were treated with hook plate fixation, and were divided into two groups. Bsaed on recovery of shoulder function mostly, the patients who suffered from rest pain, motion pain were named as shoulder pain group, while the patients without pain were named as painless group. In shoulder pain group, there were 21 cases including 15 males and and 6 females ranging the age from 22 to 62 years old with an average of (40.6±11.2) years old. There were 8 cases were on the left side and 13 cases were on the right side. In painless group, there were 65 cases including 36 males and and 29 females ranging the age from 19 to 65 years old with an average of (40.0±11.3) years old. There were 33 cases were on the left side and 32 cases were on the right side. The time from injury to operation ranged from 3 h to 8 d with an average of 34.6 h. Shoulder function of all patients were normal before injuried. Postoperative pain, activity of daily living (ADL), range of motion, deltoid muscle strength were compared. Anteflexion,rear protraction, abduction and upthrow of shoulder joint were also compared. Postoperative complications between two groups were observed and compared. All patients were followed up from 12 to 48 months with an average of 18.5 months. Constant-Murley score were used to evaluate clinical efficacy at the least following up, and 13 cases got an excellent results, 5 moderate, 2 good and 1 poor in shoulder pain group ; while 61 cases were obtained excellent results, 3 moderate and 1 good in painless group. There were significantly differences between two groups in Constant-Murley score and activity of shoulder joint (P<0.05). In shoulder pain group, 3 cases were disconnected, 1 case occurred stress fracture, 9 cases were subacromial impingement syndrome, 5 cases occurred subluxation, 1 case occurred plate breakage and 11 cases were acromioclavicular arthritis. Chosing individual clavicular hook plate, fulfilling anatomic reset, paying attention to the repair of articular capsule ligament, and reducing hook and bone antagonism between stress is the key point of preventing and decreasing postoperative shoulder pain.

The purpose of this study was to compare the midterm outcomes between fixed and mobile ultra-congruent (UC) bearings in total knee arthroplasty (TKA). This is a retrospective matched-pairs case-control study of patients who underwent primary navigation-assisted TKA with a minimum 5-year follow-up. A total of 182 cases involved the fixed UC bearing system as Group 1 and 101 cases involved mobile UC bearing system group as Group 2. After 1:1 matching, 73 knees in each group were enrolled. Clinical and radiographic outcomes were evaluated. The overall survival was 143 of 146 cases (97.9 %) at final follow-up, and 72 of 73 cases (96.3 %) in Group 1 and 71 of 73 cases (95.8 %) in Group 2 at final follow-up based on an endpoint of revision surgery. The reasons of revision TKA were periprosthetic fracture in Group 1, infection and bearing dislocation in Group 2. There was no statistical difference in Hospital for Special Surgery (HSS) scores, Knee Society Scores (KSS), WOMAC index score evaluations between groups. This study demonstrated that the fixed-bearing UC prosthesis could provide satisfactory performance compared with that of the mobile-bearing UC prosthesis with minimum 5-year follow-up. The fixed-bearing UC prosthesis could be considered in navigation-assisted TKA with theoretical advantages of UC design. IV.

To compare embryo transfer (ET) technique based on catheter rotation during its withdrawal in cases with unexplained infertility in a prospective, randomized trial (NCT03097042). Two hundred intracytoplasmic sperm injection (ICSI) patients undergoing ET with cleaving or blastocyst-stage fresh embryos were randomized into 2 groups: cases with (n = 100), and without (n = 100) catheter rotation during its withdrawal. Groups were matched for age and some clinical parameters. A soft catheter was used to transfer a single embryo with catheter rotation during its withdrawal in the study group and without rotation in the control. The use of a stiff catheter or tenaculum was not needed in any case. Groups were compared in terms of cycle characteristics and clinical pregnancy rates. Pregnancy rate was significantly higher in the study group (41 vs. 26%, p = 0.04). Clinical pregnancy rate was also significantly higher in the study group (39 vs. 25%, OR 1.9 [1.1-3.5], p = 0.05). On the other hand, the ongoing pregnancy rate was similar between the 2 groups (33 vs. 23%, p = 0.2). Catheter rotation during its withdrawal may be associated with increased pregnancy and clinical pregnancy rates; however, the difference in ongoing pregnancy rates did not reach statistical significance. © 2018 S.

Objective To calculate the yield and cost per diagnosed tuberculosis (TB) case for three World Health Organization screening algorithms and one using the Chinese National TB program (NTP) TB suspect definitions, using data from a TB prevalence survey of people aged 65 years and over in China, 2013. Methods This was an analytic study using data from the above survey. Risk groups were defined and the prevalence of new TB cases in each group calculated. Costs of each screening component were used to give indicative costs per case detected. Yield, number needed to screen (NNS) and cost per case were used to assess the algorithms. Findings The prevalence survey identified 172 new TB cases in 34,250 participants. Prevalence varied greatly in different groups, from 131/100,000 to 4651/ 100,000. Two groups were chosen to compare the algorithms. The medium-risk group (living in a rural area: men, or previous TB case, or close contact or a BMI <18.5, or tobacco user) had appreciably higher cost per case (USD 221, 298 and 963) in the three algorithms than the high-risk group (all previous TB cases, all close contacts). (USD 72, 108 and 309) but detected two to four times more TB cases in the population. Using a Chest x-ray as the initial screening tool in the medium risk group cost the most (USD 963), and detected 67% of all the new cases. Using the NTP definition of TB suspects made little difference. Conclusions To “End TB”, many more TB cases have to be identified. Screening only the highest risk groups identified under 14% of the undetected cases,. To “End TB”, medium risk groups will need to be screened. Using a CXR for initial screening results in a much higher yield, at what should be an acceptable cost. PMID:28594824

This randomized controlled study compared two types of case management for skilled nursing level patients living at home: the centralized individual model and the neighborhood team model. The team model differed from the individual model in that team case managers performed client assessments, care planning, some direct services, and reassessments; they also had much smaller caseloads and were assigned a specific catchment area. While patients in both groups incurred very high estimated health services costs, the average annual cost during 1983-85 for team cases was 13.6 percent less than that of individual model cases. While the team cases were 18.3 percent less expensive among "old" patients (patients who entered the study from the existing ACCESS caseload), they were only 2.7 percent less costly among "new" cases. The lower costs were due to reductions in hospital days and home care. Team cases averaged 26 percent fewer hospital days per year and 17 percent fewer home health aide hours. Nursing home use was 48 percent higher for the team group than for the individual model group. Mortality was almost exactly the same for both groups during the first year (about 30 percent), but was lower for team patients during the second year (11 percent as compared to 16 percent). Probable mechanisms for the observed results are discussed.

To compare the effectiveness and complications of TVT-Abbrevo (tension-free vaginal tape-Abbrevo) and TVT-Obturator (tension-free vaginal tape-obturator) for the treatment of female stress urinary incontinence (SUI). From Nov.2012 to Nov.2013, 117 patients suffering from SUI were treated with TVT-Abbrebo (n=79) or TVT-Obturator (n=38) procedure, the clinical efficacy and operation-correlated complications were observed. A total of 117 cases, 107 cases of urinary incontinence symptoms disappeared completely, 10 cases were improved. 72 cases (91.1%) were cured and 7 cases (8.9%) were improved in TVT-Abbrevo group; 35 cases (92.1%) were cured and 3 cases (7.9%) were improved in TVT-Obturator group. No significant differences could be found for the curing rates between two groups (P>0.05). Compared with the TVT-Obturator group, the TVT-Abbrevo group had less patients complaining of inner thigh pain at 24 h and 1 w after surgery (P<0.05). No significant differences were observed for the incidence of inner thigh pain at 1m and 1y after surgery between TVT-Abbrevo and TVT-Obturator group (P>0.05). No intraoperative complications such as blood vessel, nerve, bladder damage were recorded and no postoperative retropubic hematoma, tape adjustment and other complications occurred in two goups. No recurrence after 1 year follow-up. The study shows that TVT-Abbrevo procedure is safe and efficacy in treatment of SUI, and associated with low incidence of recent postoperative inner thigh pain.

Video-assisted thoracic surgical (VATS) lobectomy is gaining popularity in the treatment of lung cancer. The aim of this study is to investigate the learning curve of VATS lobectomy by using multidimensional methods and to compare the learning curve groups with respect to perioperative clinical outcomes. We retrospectively reviewed a prospective database to identify 67 consecutive patients who underwent VATS lobectomy for lung cancer by a single surgeon. The learning curve was analyzed by using moving average and the cumulative sum (CUSUM) method. With the moving average and CUSUM analyses for the operation time, patients were stratified into two groups, with chronological order defining early and late experiences. Perioperative clinical outcomes were compared between the two learning curve groups. According to the moving average method, the peak point for operation time occurred at the 26th case. The CUSUM method also showed the operation time peak point at the 26th case. When results were compared between early- and late-experience periods, the operation time, duration of chest drainage, and postoperative hospital stay were significantly longer in the early-experience group (cases 1 to 26). The intraoperative estimated blood loss was significantly less in the late-experience group (cases 27 to 67). CUSUM charts showed a decreasing duration of chest drainage after the 36th case and shortening postoperative hospital stay after the 37th case. Multidimensional statistical analyses suggested that the learning curve for VATS lobectomy for lung cancer required ∼26 cases. Favorable intraoperative and postoperative care parameters for VATS lobectomy were observed in the late-experience group.

Hospitalized cases of community-acquired pneumonia (CAP) of the elderly with a history of neurologic diseases have not been examined in detail in the past. We extracted 15 cases with a history of neurologic disease (neurological history group, NH, all cases were over 70 years old), and 22 age-matched cases without a history of neurological diseases (non neurologic history group, non-NH) among 47 CAP patients who admitted to our hospital from home during the past year, and compared the two groups in terms of: (1) the score of severity of pneumonia by A-DROP system, (2) outcome (3) the duration of hospitalization, (4) the duration from end of treatment of antibiotic treatment to discharge, compared between the survival discharge cases out of two groups (11 vs 22 cases), (5) the bacteria that were detected. (1) In the NH group, the score was significantly higher than that in the non-NH group. (2) In the NH group, 4 cases died while none did in the non-NH group. (3) In the NH group, it was 30.8 +/- 22.8 (average +/- standard deviation) days, significantly higher than the 17.6 +/- 5.9 days in the non-NH group, (4) In the NH group, it was 16.6 +/- 14.1 days, which was significantly higher than the 6.7 +/- 4.8 days in the non-NH group. (5) In the NH group, there was a high rate of detection of Klebsiella pneumoniae, Escherichia coli and Serratia marcesscense. An original comprehensive plan of treatment and care support is necessary for NH because the NH is different from other CAP conditions.

One hundred and seventy-eight cases of unicameral bone cysts (UBC) treated with curettage and bone grafting were compared to 141 cases treated with cortisone injections. The end results were comparable in the two groups. Local recurrence risk factors in the surgical group were active cyst and previous operations. In the other group they were multilocation of the cyst, active cyst, and size of cyst. A new radiographic classification of aneurysmal bone cyst (ABC) is proposed in a report of 198 cases of ABC. The treatment of choice in ABC is surgical and the type (curettage, curettage plus phenole or cryosurgery, resection or hemiresection) is selected on the basis of the radiographic aspect and the rate of growth of the cyst. Radiotherapy is only indicated in inoperable ABC cases.

To compare clinical effect of T-shaped locking internal fixation and external fixation in treating dorsal Barton's fracture,and investigate selective strategy of internal fixation. From January 2008 to January 2013, 100 patients with dorsal Barton's fracture were randomly divided into two groups. In treatment group, there were 30 males and 20 females with an average age of (33.8±3.6) years old;30 cases were type B, 20 cases were type C;and treated with T-shaped locking internal fixation. In control group, there were 32 male and 18 females with an average age of (32.9±3.4) years old; 29 cases were type B, 21 cases were type C; and treated with external fixation. Volar tilt, ulnar deviation and radial height at 3 months after operation were detected and compared between two groups. Mechara functional evaluation were used to evaluate postoperative clinical effects. Clinical cure time, postoperative complications,joint mobility and function score were recorded and compared between two groups. In treatment group,volar tilt was (11.9±2.7)°, ulnar deviation was (20.8+ 2.9)°,and radial height was (10.9±1.8) mm; while volar tilt was (9.1±1.6)°, ulnar deviation was (17.1±2.9)°, and radial height was (8.1±1.5) mm in control group. Treatment group was better than control group in volar tilt, ulnar deviation and radial height. Clinical cure time in treatment group was(12.0±2.3) weeks, shorter than control group (18.0±4.1) weeks. The incidence of complications in treatment group was lower than control group. According to Mehara functional evaluation,20 cases got excellent results, 25 good, 3 moderate and 2 poor in treatment group; 16 cases got excellent results, 14 good, 10 moderate and 10 poor in control group. Treatment group was better than control group in clinical effects.

To explore influence of sodium restricted diet and non-sodium restricted diet on plasma rennin (PRA), angiotensin II (All), ALD, renal blood flow (RBF) and subside of ascites in patients with cirrhotic ascites. Eighty cases of hepatitis B with cirrhotic ascites were randomly divided into sodium restricted diet group and non-sodium restricted diet group. 39 cases were in non-sodium restricted diet group, taking sodium chloride 6500-8000 mg daily; 41 cases were in sodium restricted diet group, taking sodium chloride 5000 mg daily. Both groups received diuretics furosemide and spironolactone. Blood sodium, urine sodium, PRA, AII, ALD, RBF ascites subsiding were compared after treatment. In non-sodium restricted diet group, blood sodium and urine sodium increased 10 days after treatment compared with those before treatment, and compared with those of sodium restricted diet group 10 days after treatment, P <0. 01. RBF increased compared with that before treatment, and compared with that of sodium restricted diet group 10 days after treatment, P < 0. 01. Renal damage induced by low blood sodium after treatment was less in non-sodium restricted diet group than that in sodium restricted diet group, P <0. 05. Ascites disappearance upon discharge was more in sodium restricted diet group than that in non-sodium restricted diet group, P <0. 01. Time of ascites disappearance was shorter in non-sodium restricted diet group than that in sodium restricted diet group, P < 0. 01. Compared with sodium restricted diet, while using diuretics of both groups, non-sodium restricted diet can increase level of blood sodium, thus increasing excretion of urine sodium and diuretic effect. It can also decrease levels of PRA, AII and ALD, increase renal blood flow and prevent renal damage induced by low blood sodium and facilitate subsiding of ascites.

172 cases of pregnant women scheduled for delivery by cesarean section were randomly assigned to 59 cases in modification group with modified Misgav Ladach technique, 57 cases in Misgav Ladach group with Misgav Ladach technique and 56 cases in Pfannenstiel group with Pfannenstiel technique from May to Dec. 1999. The modified points included: transversely incising the fascia 2 to 3 cm, then dividing it bluntly; without opening and dissociating the visceral peritoneum; two layers suturing of low transverse uterine incision; closing the skin by continuous suturing. Results showed the average delivery time in the modification group was (3.6 +/- 2.6) min and (5.7 +/- 2.9) min in the Misgav Ladach group (P < 0.05). Median operating time was (28.3 +/- 5.4) min in modification group compared with (27.5 +/- 6.5) min in the Misgav Ladach group (P > 0.05). Average blood loss was (128 +/- 35) ml in modification group compared with (212 +/- 147) ml in the Pfannenstiel group (P < 0.05). It was concluded that the modified Misgav Ladach technique not only preserved all advantages of Misgav Ladach method, but also had additional advantages, such as faster in delivering the fetus, less damage, easier mastering for obstetricians.

The purpose of this study is to compare the surgical and imaging outcome in children who underwent brain tumour surgery with intention of complete tumour resection, prior to and following the start of intra-operative MRI (ioMRI) service. ioMRI service for brain tumour resection commenced in October 2009. A cohort of patients operated between June 2007 and September 2009 with a pre-surgical intention of complete tumour resection were selected (Group A). A similar number of consecutive cases were selected from a prospective database of patients undergoing ioMRI (Group B). The demographics, imaging, pathology and surgical outcome of both groups were compared. Thirty-six of 47 cases from Group A met the inclusion criterion and 36 cases were selected from Group B; 7 of the 36 cases in Group A had unequivocal evidence of residual tumour on the post-operative scan; 5 (14%) of them underwent repeat resection within 6 months post-surgery. In Group B, ioMRI revealed unequivocal evidence of residual tumour in 11 of the 36 cases following initial resection. In 10 of these 11 cases, repeat resections were performed during the same surgical episode and none of these 11 cases required repeat surgery in the following 6 months. Early repeat resection rate was significantly different between both groups (p = 0.003). Following the advent of ioMRI at our institution, the need for repeat resection within 6 months has been prevented in cases where ioMRI revealed unequivocal evidence of residual tumour.

The endoscopic technique has been utilized to harvest muscle flaps and detect perforators of fasciocutaneous flaps. This study aimed to compare the perioperative outcomes between the endoscope-assisted technique and handheld acoustic Doppler for perforator identification in fasciocutaneous flaps.This retrospective case-control study included patients who underwent fasciocutaneous flap reconstruction for traumatic soft tissue defects. In the case group, perforator identification was assisted by the endoscope-assisted technique. In the control group, age- and sex-matched patients received handheld acoustic Doppler to detect perforators. Perioperative outcomes, flap characteristics, and postoperative complications were compared.There were 12 patients in the case group and 12 in the control group. Compared with the control group, the case group had a significantly shorter length of donor-site wounds (9 cm vs 12 cm, P = .023) and a significantly smaller proportion of patients receiving skin grafting at the donor sites (0% vs 41.7%, P = .037). The case group had a longer operative time, but the difference was not statistically significant (180 minutes vs 150 minutes, P = .367). The amount of blood loss, the time length of postoperative drainage, and complications did not significantly differ between the 2 groups.The endoscope-assisted technique for perforator identification of fasciocutaneous flaps provided less donor-site morbidity and a significantly shorter length of donor-site wounds than the conventional handheld acoustic Doppler, which suggests that this technique could be a valuable alternative when a precise design is indicated.

To compare efficacy and safety of visual internal urethrotomy (VIU) using holmium laser (Ho:YAG) (group A) versus cold knife (group B) in children with urethral strictures. It may be the first comparative study on this issue in children. This study compared Ho:YAG group, which was evaluated prospectively from January 2014 till January 2016, versus cold knife group, which was a historical control performed from March 2008 till February 2010. Children ≤ 13 years old with urethral strictures ≤ 1.5 cm were included successively. Recurrent cases, congenital obstructions and cases with complete arrest of dye in voiding cystourethrography were excluded. Scar tissue was incised at twelve o'clock. Outcome was compared using Student's t, Mann-Whitney, Chi-square or Fisher exact tests as appropriate. Each group included 21 patients. Mean age was 6.27 ± 3.23 (2-13) years old. Mean stricture length was 1.02 versus 1 cm in group A versus B, respectively (p = 0.862). Ten cases of penile/bulbous strictures and another 11 cases of membranous strictures were found in each group. There was no significant difference between both groups in preoperative data. Success rate for initial VIU was 66.7% in group A versus 38% in group B (p = 0.064). This was associated with significantly higher Q max in group A (mean 16.52 vs 12.09 ml/s; p = 0.03). Success rate after two trials of VIU was 76.2% for group A and 47.61% for group B (p = 0.057). No complications were reported in both groups. Laser VIU has a higher success rate than cold knife VIU for urethral strictures ≤ 1.5 cm in children with significantly higher Q max . Both are easy to perform, low invasive and safe.

The utility of the Appropriate Use Criteria (AUC) for amyloid imaging is not established. Fifty-three cognitively impaired patients with clinical F 18 -florbetapir imaging were classified as early and late onset, as well as AUC-consistent or AUC-inconsistent. Chi-square statistics and t test were used to compare demographic characteristics and clinical outcomes as appropriate. Early-onset patients were more likely to be amyloid positive. Change in diagnosis was more frequent in late-onset cases. Change in therapy was more common in early-onset cases. AUC-consistent and AUC-inconsistent cases had comparable rates of amyloid positivity. We saw no difference in the rate of treatment changes in the AUC-consistent group as opposed to the AUC-inconsistent group. The primary role of amyloid imaging in the early-onset group was to confirm the clinically suspected etiology, and in the late-onset group in detecting amyloid-negative cases. The rate of therapeutic changes was significantly greater in the early-onset cases.

To compare the efficacy and complication of tissue selecting therapy stapler (TST) and procedure for prolapse and hemorrhoids (PPH) in the treatment of severe hemorrhoids. Clinical data of 542 cases of severe hemorrhoids undergoing TST (258 cases) or PPH (284 cases) in The First Affiliated Hospital of Fujian Medical University from November 2010 to January 2012 were analyzed retrospectively. Operative parameters, efficacy and complication 3 months after operation were assessed and compared. No significant difference in cure rate between TST and PPH (96.5% vs. 95.4%) was found, while the operation time and hospital stay after operation in TST group were significantly shorter urgency [(20.6±4.7) vs. (26.4±6.3) min, (2.9±0.5) vs. (3.5±0.7) d, both P<0.05]. Incidences of postoperative pain, bleeding, anal urgency and urinary retention in TST group were significantly lower than those in PPH group (all P<0.01). No anal stenosis was observed in TST group, and 5 cases developed anal stenosis in PPH group (P<0.05). Hemorrhoid recurrence did not differ significantly between the two groups. The efficacy of TST and PPH is comparable for severe hemorrhoids patients, while TST is associated with faster postoperative recovery and less complications.

To evaluate functional and radiographic results of arthroscopic suture anchor repair for posterior root tear of the medial meniscus (PRTMM) and compare with pullout suture repair. From December 2006 to August 2008, 51 consecutive patients underwent arthroscopic repair of PRTMM at our hospital. The repair technique was switched over time from pullout suture repair (group 1) to suture anchor repair (group 2). Of the patients, 6 were lost to follow-up, leaving a study population of 45 patients, with 22 menisci (48.9%) in group 1 and 23 (51.1%) menisci in group 2. The mean follow-up duration was 25.9 months (range, 24 to 27 months) in group 1 and 26.8 months (range, 24 to 28 months) in group 2. Compared variables included International Knee Documentation Committee criteria, Kellgren-Lawrence grade, gap distance at PRTMM, structural healing, meniscal extrusion, and cartilage degeneration of the medial femoral condyle. At 2 years postoperatively, both groups showed significant improvements in function (P < .05) and did not show significant differences in Kellgren-Lawrence grade (P > .05) compared with preoperatively. On magnetic resonance imaging, the gap distance at PRTMM was 3.2 ± 1.1 mm in group 1 and 2.9 ± 0.9 mm in group 2 preoperatively (P > .05). Complete structural healing was seen in 11 cases in group 1 and 12 cases in group 2 (P > .05). Mean meniscal extrusion of 4.3 ± 0.9 mm (group 1) and 4.1 ± 1.0 mm (group 2) preoperatively was significantly decreased to 2.1 ± 1.0 mm (group 1) and 2.2 ± 0.8 mm (group 2) postoperatively (P < .05). Regardless of repair technique, incompletely healed cases showed progression of cartilage degeneration (4 cases in group 1 and 2 cases in group 2). For PRTMM, our results show significant functional improvement in both the suture anchor repair and pullout suture repair groups. Reduction of meniscal extrusion seems to be appropriate to preserve its protective role against progression of cartilage degeneration after complete healing at PRTMM.

The current prospective randomized study was designed to compare the effects of intracavitary (i.c.) chemotherapy vs immunotherapy vs immunochemotherapy for malignant effusion. Between 1992 and 1995, a total of 42 patients with malignant effusion were registered, and 41 patients were eligible for statistical analysis. The primary diseases of the eligible patients included 27 gastric, four colorectal, four pancreatic, three lung, two liver and one oesophageal cancers. The patients with malignant effusion were randomly assigned into one of three i.c. therapeutic regimens: chemotherapy alone with weekly injection of anticancer agents (ACAs: cisplatin, mitomycin-C, adriamycin, etc.) (Group A, n = 13); immunotherapy alone with weekly injection of streptococcal preparation OK-432 (Group B, n = 14); or immunochemotherapy with ACAs and OK-432 (Group C, n = 14). The response of the effusion, patient survival and the kinetics of cytokines in the effusion were compared. There were no differences in the patients' backgrounds. The side-effects of the regimens included pain, anorexia, fever, leucopenia and anaemia and there were no differences in their incidence among the three groups. One patient died after cisplatin (CDDP) administration in Group A. Cytologic examination revealed that tumour cells in the effusion disappeared in 23% of Group A cases, 36% of Group B cases and 36% of Group C cases. The malignant effusion did not disappear in any of the Group A cases; however, the effusion disappeared in 29% of Group B cases and 43% of Group C cases (P = 0.03, Group A vs Group C). Furthermore, the 50% survival period was 1.6 months for Group A, 2.4 months for Group B and 3.5 months for Group C. The 6-month survival rate was 7% for Group A, 6% for Group B and 34% for Group C, and the 1-year survival rate was 0%, 0% and 17% respectively (P = 0.048, Group A vs Group C by the log-rank test). The analysis of the cytokine kinetics revealed a prominent increase in the level of interleukin-6 in the effusion in Group C. These results suggest that i.c. immunochemotherapy with OK-432 and ACAs may be more beneficial than i.c. chemotherapy alone or immunotherapy alone. © 1999 Cancer Research Campaign PMID:10360655

Objective: This analysis was performed to evaluate the efficacy in stroke prevention and safety of dabigatran in Chinese nonvalvular atrial fibrillation(NVAF) patients enrolled in RE-LY trial. Methods: RE-LY was an prospective, open-label, randomized, multicenter study. From March 2006 to March 2009, 541 atrial fibrillation patients at risk of stroke were recruited from 13 medical centers in China. Patients randomly received, in a blinded fashion, fixed doses of dabigatran-110 mg or 150 mg twice daily or, in an unblinded fashion, adjusted-dose warfarin. The primary efficacy endpoint was stroke or systemic embolism. The primary safety endpoint was major bleeding. Results: The incidence of stroke in the Chinese subpopulation was 1.94% per year(7 cases) in the group that received 110 mg of dabigatran (dabigatran 110) and 1.10% per year(4 cases) in the group that received 150 mg of dabigatran (dabigatran 150), as compared with 2.87% per year (10 cases) in warfarin group . Incidence of ischemic stroke was 1.11% per year(4 patients) in dabigatran 110 group, 0.82% per year(3 cases) in dabigatran 150 group and 2.01% per year(7 patients) in warfarin group. Incidence of hemorrhagic stroke was 0.28% per year(1 case) in dabigatran 110 group, 0.27% per year(1 case) in dabigatran 150 group and 0.57% per year(2 cases) in warfarin group. All-cause mortality was similar among the three treatment groups: 3.33% per year(12 cases) in dabigatran 110, 2.19% per year(8 cases) in dabigatran 150 and 2.58% per year(9 cases) in warfarin group. Incidence of major bleeding event was 0.56% per year(2 cases) in both dabigatran groups, as compared with 1.43% per year(5 cases) in warfarin group. Gastrointestinal disorders such as dyspepsia occurred in 12.8% patients of both dabigatran groups, and in 5.6% patients of warfarin group. Conclusions: Despite the descriptive statistical analysis in nature of present study due to the limited number of subjects, our subgroup analysis implies that like warfarin, dabigatran is efficacious and safe for thromboembolism prevention in Chinese patients with atrial fibrillation at risk of stroke.

The aim of this study was to compare the short-term outcomes of robotic rectal resection with total mesorectal excision (TME) for rectal cancer, with the use of the new da Vinci Xi® (Xi-RobTME group) and the da Vinci Si® (Si-RobTME group). Ten patients with histologically confirmed rectal cancer underwent robot-assisted TME with the use of the new da Vinci Xi. The outcomes of Xi-RobTME group were compared with a Si-RobTME group selected using a case-matched methodology. Overall operative times and mean hospital stays were shorter in the Xi-RobTME group. Surgeries were fully robotic with a complete take-down of the splenic flexure in all Xi-RobTME cases, while only four cases of the Si-RobTME group were fully robotic, with two cases of complete take-down of the splenic flexure. The new da Vinci Xi could offer some advantages with respect to the da Vinci Si in rectal resection for cancer. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Egg cases of the genus Apristurus (Chondrichthyes: Scyliorhinidae): phylogenetic and ecological implications.

PubMed

Flammang, Brooke E; Ebert, David A; Cailliet, Gregor M

2007-01-01

The genus Apristurus has been divided formerly into three species subgroups based on morphological and molecular phylogenies. Previous studies have agreed on the separation into distinct species groups, the largest two of which have been described as the brunneus and spongiceps groups. An examination of the egg cases produced by these oviparous catsharks corroborates the distinction in species groups: egg cases of the brunneus group have long fibrous and curly tendrils at either end, whereas egg cases of the spongiceps group lack tendrils. The egg cases of A. kampae, A. manis, A. spongiceps and Apristurus sp. D are described for the first time, and the egg cases of A. brunneus and A. riveri are re-described to include comparable morphological characteristics. The ecological implications of egg case morphology on oviposition and ventilation are also discussed.

The aim of this paper is to present the assessment of a case management project, implemented with chronic patients in Valencia, for the integration of health and social care. This project is linked with the 'Sustainable Socio-Health Model'. Health department 06 in Valencia. The target groups were chronic patients of 65 years and over. A non-randomized non-blinded comparative study with an intervention and control group. The intervention consisted in the creation of an interdisciplinary case management team, the use of a common portfolio of resources, and its application to a pilot sample with an intervention period of 6-9 months. Diseases (ICD-9), functional capacity, use of health and social resources, satisfaction, unit cost services. There was an increase in the combined use of health and social resources in the intervention group, which included social day centers (21.8% in the intervention group compared to 9.8% in the control group), in coordination with primary care (suggested as the only health resource in 55.4% of cases). There was a decrease in the number of medical visits in the intervention group (43.6% versus 74.5% in the control group). Increased patient satisfaction (55.5% in the intervention group compared to 29.4% in the control group) was observed. At least an extra 4.4% of patients were treated using hospital resources without increasing costs. Case management using a common unique portfolio of health and social resources can improve the coordination of resources, increases patient satisfaction and increases the capacity of using of hospital resources.

2015-07-01

The efficacy of anterior fusion using zero-profile implant (Zero-P) in the surgical treatment of degenerative cervical disease was investigated through radiographic and clinical comparisons with existing treatments using autograft or allograft and anterior plating. A total of 130 patients who underwent anterior decompression and fusion for degenerative cervical spine disease with a follow-up of at least 1 year were analyzed retrospectively. The cases were divided into three groups: autograft and plate (38 cases, group A), allograft and plate (44 cases, group B), and Zero-P (48 cases, group C). Maintenance of lordosis, extent of subsidence, and fusion were evaluated radiologically and compared among preoperative, postoperative, and final follow-up time points. In addition, changes in Visual Analog Scale (VAS) and Neurologic Disability Index (NDI) scores and the presence of complications were evaluated for clinical analysis. Operation time was significantly less in group C (p = 0.007, 0.002). Maintenance of entire and segmental lordosis after surgery was better in groups A and B compared with group C (p = 0.002, 0.001); however, the extent of loss of lordosis from the surgery to the final follow-up did not show any significant differences. Regarding the extent of subsidence, the increase of height between the vertebral bodies after the surgery was 3.10, 2.89, and 2.68 mm in group A, group B, and group C, respectively (p = 0.14), and changed to - 1.27, - 2.41, and - 1.2 mm at the final follow-up (p = 0.012). VAS and NDI scores were improved from 7.2 to 3 and 34 to 12, respectively, but there were no significant differences. Nonunion occurred in two cases in both group B and group C. In terms of clinical complications, two cases of persistent donor site pain were found in group A; one case of persistent dysphagia was found in both group A and group B. Anterior cervical fusion using Zero-P has a shorter operation time and less subsidence compared with conventional surgical techniques. Thus it can be considered a useful technique for the surgical treatment of degenerative cervical disease. Georg Thieme Verlag KG Stuttgart · New York.

To evaluate the advantages and disadvantages of early-early pregnancy induced abortion (EPIA). A total of 10 404 cases of EPIA performed at our hospital from January 1993 to December 2003 were retrospectively analyzed and compared with 9434 cases of common induced abortion (CIA). The amount of hemorrhage and operative duration, degree of pain, rate of induced-abortion syndrome, rate of incomplete abortion, menstrual changes and post-operative onset of Asherman's syndrome were observed and compared between 2 groups. The average age, ratio of parous cases, ratio of the cases of first-pregnancy induced abortion were not different between 2 groups (P > 0.05). The amount of hemorrhage bleeding ((4.9 ± 3.2) ml), operative duration ((90.3 ± 12.4) s), degree of pain, rate of induced-abortion syndrome, menstrual changes and the rate of Asherman's syndrome in the EPIA group were all significantly less than those in the CIA group (P < 0.05). However, the rate of incomplete abortion (0.44%) in the EPIA group was significantly higher than that (0.21%) in the CIA group (P < 0.05). EPIA has the advantages of lesser hemorrhage, less pain, shorter operative duration and fewer complications over CIA. Therefore the recovery of EPIA cases is earlier than that of CIA cases. While the risk of incomplete abortion stays high.

To analyze the possible association of maternal age with the risk of all congenital abnormalities (CAs) in a population-based large case-matched control data set. The Hungarian Case-Control Surveillance of Congenital Abnormalities included 21,494 cases with isolated CA and their 34,311 matched controls. First the distribution of maternal age groups in 24 CA-groups and their matched controls was compared. In the second step, young (19 years or less) and advanced (35 years or more) age groups were compared. Finally, the subgroups of neural-tube defects, congenital heart defects and abdominal wall's CA were evaluated separately. A higher risk of gastroschisis, congenital heart defects, particularly left-sided obstructive defects, undescended testis and clubfoot was found in the youngest age group (19 years or less) of cases. The higher proportion of pregnant women with advanced age (i.e. 35 years or more) showed only a borderline excess in cases with clubfoot. The so-called U-shaped risk of maternal age distribution was found in cases with clubfoot and in the total group of isolated CAs. The maternal age is a contributing factor to the origin of some isolated CAs mainly in young pregnant women.

In 1997, the number of newly registered patients with pulmonary tuberculosis increased, compared with that in 1996, in Japan. The majority of the increase were occupied by elder patients 70 years of age or higher. But in younger group less than 30 years old, a reduction in the incidence of tuberculosis had been slowed down, until 1996. The purpose of this report is to elucidate the characteristics of these younger patients. 139 cases younger than 30 years of age, who were hospitalized in the tuberculous ward of IMCJ from April 1995 to March 1998, were investigated, and were compared with the control group (557 cases), 30-79 years old who were hospitalized during the same period. In the younger group, the proportion of women cases, discovered by health examination, foreigners, and contact with TB patients in the past was significantly higher than in the control group. But there were no difference between the both groups, concerning the proportion of those spending irregular life or living alone. The proportion of sputa smear negative cases was significantly higher in the younger group than in the control. For early diagnosis of TB among younger group, the application of bronchofiberscopy and nucleic acid diagnostic method, are encouraged.

A navigation system should improve the quality of a total knee prosthesis implantation in comparison to the classical, surgeon-controlled operative technique. The authors have implanted 40 knee total prostheses with an optical infrared navigation system (Orthopilot AESCULAP, Tuttlingen--group A). The quality of implantation was studied on postoperative long leg AP and lateral X-rays, and compared to a control group of 40 computer-paired total knee prostheses o the same model (Search Prosthesis, AESCULAP, Tuttlingen) implanted with a classical, surgeon-controlled technique (group B). An optimal mechanical femorotibial angle (3 degrees valgus to 3 degrees varus) was obtained by 33 cases in group A and 31 cases in group B (p > 0.05). Better results were seen for the coronal and sagittal orientation of both tibial and femoral components in group A. Globally, 26 cases of the group A and 12 cases of the group B were implanted in an optimal manner for all studied criteria (p < 0.01). The used navigation system allows a significant improvement of the quality of implantation of a knee total prosthesis in comparison to a classical, surgeon-controlled instrumentation. Long-term outcome could be consequently improved.

The aim of the study was to compare the outcomes of regenerative endodontic treatment (RET) and apexification on immature permanent teeth with pulp necrosis and apical periodontitis. A total of 118 patients (118 teeth) were recruited and randomly assigned to either RET or apexification treatment. Each treatment group was divided into 2 subgroups according to the etiology: dens evaginatus or trauma. Clinical symptoms and complications were recorded, and cone-beam computed tomographic imaging with a limited field of view was used to measure the change of root length, root thickness, and apical foramen size at the 12-month follow-up. The t test/rank sum test and Fisher exact test were applied to compare the change of root morphology between RET and apexification. One hundred three of 118 cases were completed at the 12-month follow-up. The survival rate was 100% for both treatment groups. All cases were asymptomatic with apical healing. The RET group showed a significant increase in root length and root thickness compared with the apexification group (P < .05). In the RET group, the cases caused by dens evaginatus achieved increased root length and root thickness compared with those caused by trauma (P < .05). RET and apexification achieved a comparable outcome in regard to the resolution of symptoms and apical healing. RET showed a better outcome than apexification regarding increased root thickness and root length. The etiology had an impact on the outcome of RET. Dens evaginatus cases showed better prognoses than trauma cases after RET. Copyright © 2017 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

To investigate the role of endoscopic endonasal transsphenoidal surgery and the pseudocapsule in the treatment of growth hormone adenomas. The study included 43 patients (age range, 21-64 years) with growth hormone adenomas treated with an endoscopic endonasal approach. We compared the tumor characteristics and surgical outcomes of cases with (group A, 21 cases, from November 2013 to January 2015) and without (group B, 22 cases, from October 2011 to October 2013) extra-pseudocapsule resection. The preoperative demographics, tumor characteristics, and surgical complications were not significantly different between groups A and B. Postoperative remission without adjuvant therapy was achieved in 18 of 21 cases (85.7%) in group A, which was significantly greater than that observed in group B (12 of 22 cases [54.4%]). In group A, the pseudocapsules were verified by endoscopy and histopathology. The pseudocapsule was removed en bloc with the whole adenoma in only 5 cases (23.8%). For the remaining 16 patients (76.2%), following extra-pseudocapsule dissection, incomplete pseudocapsule removals with intracapsule procedures were achieved. The combination of extra-pseudocapsule resection and endoscopy led to a high rate of gross total tumor resection and endocrinologicl remission in acromegalic patients compared with the group with intracapsular resection. Extra-pseudocapsule resection resulted in no additional postoperative complications. Copyright © 2016. Published by Elsevier Inc.

Early HIV diagnosis and initiation onto antiretroviral therapy may prevent ongoing spread of HIV. Risk Tracing Snowball Approach (RTSA) has been shown to be effective in detecting new HIV cases in other settings. The main objective of this study is to evaluate the effectiveness of RTSA in increasing the rate of newly identified HIV cases among high-risk populations. Our second objective was to evaluate the effectiveness of RTSA, as compared to the walk-in group, in increasing the number of HIV tests and early case detection. This study was conducted from April 1 to September 30, 2016 at two NGO clinics in Phnom Penh, Cambodia. Respondent driven sampling method was adapted to develop RTSA to reach high-risk populations, including key populations and the general population who have social connections with key populations. Bivariate and multivariate logistic regression analyses were conducted. During the implementation period, 721 clients walked in for HIV testing (walk-in group), and all were invited to be seeds. Of the invited clients, 36.6% agreed to serve as seeds. Throughout the implementation, 6195 coupons were distributed to seeds or recruiters, and resulted in 1572 clients visiting the two clinics with coupons (RTSA group), for a coupon return rate of 25.3%. The rate of newly identified HIV cases among the RTSA group was significantly lower compared to that in walk-in group. However, the highest number of newly identified HIV cases was found during the implementation period, compared to both pre- and post-implementation period. Although statistically not significant, the mean CD4 count of newly identified HIV cases detected through RTSA was almost 200 cells/mm3 higher than that in the walk-in group. Although the rate of newly identified HIV cases among the RTSA group was lower than that in the walk-in group, the inclusion of RTSA in addition to the traditional walk-in method boosted new HIV case detection in the two participating clinics. A higher mean CD4 count for the RTSA group may reveal that RTSA may be able to detect HIV cases earlier than the traditional walk-in approach. Further research is needed to understand whether RTSA is a cost-effective intervention to prevent ongoing spread of the HIV among high-risk populations in Cambodia.

Slow graft function (SGF) can influence overall prognosis in patients receiving deceased donor kidney transplantation (DKT). However, the impact of SGF on renal function remains uncertain. We investigated retrospectively renal function in cases with SGF compared with early graft function (EGF) and delayed graft function (DGF). Renal function after transplantation was analyzed in 199 patients who underwent DKT. Patients were classified into 130 (65.3 %) cases with EGF, 27 (13.6 %) cases with SGF, 6 (3.0 %) cases with DGF and one dialysis (DGF1), and 36 (18.1 %) cases with DGF and two or more dialyses (DGF2). The 1-year estimated glomerular filtration rate (eGFR) in the SGF group was lower than that in the EGF group (P = 0.027), but the rate of eGFR decline did not differ between the groups. The risk factors for renal function were evaluated using the area under the eGFR curve over 3 years (AUCeGFR). Donor age was negatively, and recipient age and the number of HLA matches were positively correlated with the AUCeGFR (all P < 0.05). A multivariate analysis revealed that the AUCeGFR was lower in cases of younger recipient age, older donor age, and acute rejection (all P < 0.05). The AUCeGFR was significantly lower in the SGF and DGF2 groups compared with the EGF group (P = 0.031 and 0.006, respectively). SGF may be an independent risk factor for poor renal function after DKT. Moreover, it was comparable to DGF. Efforts should be dedicated to minimizing the development of SGF and DGF.

To identify whether expansive open-door laminoplasty (Lam) is more appropriate than laminectomy and instrumented fusion (LIF) for cases with ossification of the posterior longitudinal ligament (OPLL) and straight cervical lordosis. A total of 67 cases were included and divided into Group Lam (n = 32) and Group LIF (n = 35), and the mean follow-up periods were 38 and 42 months, respectively. The cervical lordosis was elevated by C2-7 Cobb angle and cervical sagittal balance by C2-C7 sagittal vertical axis (SVA). Japanese Orthopedic Association (JOA), neurological recovery rate (RR) being calculated by the JOA, visual analog scale (VAS) and neck disability index (NDI) were used to assess clinical outcomes. Differences in general data between two groups were not significant. Total blood loss and operation duration in Group Lam were both significantly less than that in the Group LIF. By the final follow-up, the cervical lordosis significantly decreased in Group Lam and increased in Group LIF, the SVA significantly increased in Group Lam and kept unchanged in Group LIF, and the JOA, VAS, NDI significantly improved in both groups. Although there was no significant difference in RR between the two groups, cases in Group Lam had significantly larger incidence of postoperative kyphosis and kyphotic change rate, and less VAS, NDI and incidence of axial pain than cases in Group LIF. When compared with the LIF, the Lam is recommended for cases with OPLL and straight cervical lordosis when taking comparable neurological recovery, less axial pain and better neck function improvement into consideration.

To investigate the changes of ambulatory electrocardiography and peripheral blood SOD, MDA and Na+-K+-ATP enzymes in patients of acute myocardial infarction (AMI) complicated with arrhythmia. From January 2012 to March 2015, 135 cases AMI complicated with arrhythmia in our hospital were divided into 2 groups: 70 cases in the AMI uncomplicated with arrhythmia and 65 cases in the AMI complicated with arrhythmia. 62 cases volunteers accepted physical examination in our hospital in the same period were collected as the control group. 24 hour-electrocardiogram detected by ambulatory electrocardiogram (AECG), SOD and MDA in peripheral blood detected by diagnostic reagent kit and Na+-K+-ATP enzymes in peripheral blood detected by malachite green Kit Method phosphate determination method were collected. ROC curve was used to evaluate the prognostic value of SOD, MDA and Na+-K+-ATP enzymes in AMI patients. Compared with the control group, the patients had unusual ambulatory electrocardiography had increased (P <0.05), peripheral blood SOD and Na+-K+-ATP enzymes had decreased, peripheral blood MDA had increased in 2 AMI groups (P <0.05). Compared with AMI uncomplicated with arrhythmia group, the patients had unusual ambulatory electrocardiography had increased (P <0.05), peripheral blood SOD and Na+-K+-ATP enzymes had decreased, peripheral blood MDA had increased in AMI complicated with arrhythmia group (P <0.05). Among 135 cases AMI patients, 120 (88.9%) survived and 15 (11.1%) died, of whom 11 cases were AMI complicated with arrhythmia group, 4 cases were AMI uncomplicated with arrhythmia group. Compared with the AMI uncomplicated with arrhythmia group, the dead patients were more in the AMI complicated with arrhythmia group (c2 = 4.287, P = 0.038). Compared with the survival group, the SOD and Na+-K+-ATP enzymes were significantly lower (P <0.05) and MDA significantly higher (P <0.05) in the death group. The area under the ROC curve of SOD, MDA and Na+-K+-ATP enzymes were 0.958, 0.954 and 0.993 respectively, and the cut-off values were 30.66 ng/ml, 576.70 nmol/ml and 57.42 nmol/mgh, respectively. Ambulatory electrocardiography has a close relationship with the peripheral blood SOD, MDA and Na+-K+-ATP enzymes in AMI patients complicated with arrhythmia, which might predict AMI condition.

To determine the predicative significance of HRV and HRT to premature beat on patients with coal-worker's pneumoconiosis. 100 coal-worker's pneumoconiosis patients with premature beat (including 44 cases of occasional ventricular premature contraction and 56 cases of frequent ventricular premature contraction) were chosen as CWP group, and 50 healthy coal workers were chosen as control group. 24 h DCG was used to monitor and analyze the change of premature beat and to calculate HRV. Index: SDNN, SDANN, HFLF, HRT: TO, TS, compare HRV of CWP group and control group and the changes of HRT of both occasional and frequent ventricular premature contraction. The incidence of CWP at night (66.1%, 37 cases) is higher than that during daytime (33.9%, 19 cases), and the difference is statistically significant with P < 0.05. HRV (SDNN SDANN HF HL) indexes of CWP group are lower than control group, and the difference is statistically significant with P < 0.05. HRV indexes of control group at night are higher than that during daytime, and the difference is statistically significant with P < 0.05. Comparison of CWP group HRV indexes between day and night is statistically insignificant with P > 0.05. Compared with control group, TO of CWP group is higher while TS is lower, and the difference is statistically significant with P < 0.05. Compared with occasional ventricular premature contraction patients in CWP group, TO of frequent ventricular premature contraction patients is higher while TS is lower, and the difference is statistically significant with P < 0.05. Frequent ventricular premature contraction group in CWP group suffer from severe impaired autonomic nervous function injury, and abnormal HRV and HRT can be prognostic indicator of frequent ventricular premature contraction among coal-worker's pneumoconiosis patients.

Microvascular complications in type 2 diabetes (T2DM), including diabatic retinopathy (DR), diabetic kidney disease (DKD), diabetic peripheral neuropathy (DPN) are the leading causes of visual loss, end-stage renal disease or amputation, while the current therapies are still unsatisfactory. Chinese medicine (CM) has been widely used for treating diabetic mellitus. However, most of the previous studies focused on the single complication. The role of CM treatment in T2DM patients with 2 or multiple microvascular complications is not clear. To appraise the curative effect of CM in T2DM patients with 2 or multiple microvascular complications, and to compare the effects of stationary treatment and individualized treatment in T2DM patients with microvascular complications. This trial will be an 8-center, randomized, controlled study with 8 parallel groups. A total of 432 patients will be randomized to 8 groups: DR study group (32 cases) and a corresponding control group (32 cases), DR+DKD study group (64 cases) and a corresponding control group (64 cases), DR+DPN study group (64 cases) and a corresponding control group (64 cases), DR+DKD+DPN study group (56 cases) and a corresponding control group (56 cases). The control group will receive stationary treatment, and the study group will receive individualized treatment based on CM syndrome differentiation in addition to stationary treatment. The study duration will be 50 weeks, comprising a 2-week run-in period, 24 weeks of intervention, and 24 weeks of follow-up. The outcomes will assess efficacy of treatment, improvement in CM symptoms, safety assessments, adherence to the treatment, and adverse events. This study will provide evidence of evidence-based medicine for CM treatment in two or multiple microvascular complications caused by T2DM. (Registration No. ChiCTR-IPR-15007072).

The fractures of facial structures lead to great morbidity. Cross-sectional studies are needed to evaluate the current state of maxillofacial traumas. Thus, this study aims to evaluate these experiences and to compare these results with the current literature. The medical records of the maxillofacial fracture cases hospitalized between January 2004 and November 2011 were examined. The age, sex, etiology, fracture localization and treatment method for each case were documented. The affected facial bones were grouped as mandible, maxilla, zygoma, naso-orbitoethmoid complex (NOEC) and blow-out. Nasal fractures were excluded. The cases were assigned to 3 groups with respect to age (below 16, above 65 and between 17 and 64). The chi Square test was used to assess the significance of the difference in mandibular fracture rates in the pediatric population compared to others. The total number of cases was 152. The total number of fractures was 185. Of the 152 cases, 117 were male and 35 were female. The average age was 31.4 (±18.3), ranging between 2 and 81. Thirty-one cases were 16 years old or less. Nine cases were 65 years old or more. Mandibular and zygomatic fractures were the most prevalent fractures in the adult group. Mandibular fractures were significantly more common in the pediatric age group compared to rest of the population (X(2), p<0.05). Traffic accidents were the most common etiological factor, with a 55.3% ratio. Open reduction and internal fixation was the most frequently conducted treatment modality in all age groups. Retrospective studies are important for the projection of future prospects. In summary, our results indicate that pediatric fractures are mostly in the lower face and usually affect the condylar region, which is consistent with the literature.

BACKGROUND: The first heart transplantation in Canada was performed in 1968 at the Montreal Heart Institute (Montreal, Quebec). After nine patients transplanted in the precyclosporine era, the program was stopped. With the advent of cyclosporine, the program was reactivated in 1983. OBJECTIVE: To review the experience of the Montreal Heart Institute with heart transplantation between 1983 and 2005. METHODS: Three hundred patients underwent heart transplantation and were followed at the transplant clinic. Patients were divided into two groups: group 1 – first decade (1983 to 1993, n=145) and group 2 – second decade (1994 to 2005, n=155). RESULTS: There were 125 men (86%) and 20 women (14%) with a mean age of 45±10 years in group 1 compared with 118 men (76%) and 37 women (24%) with a mean age of 48±12 years in group 2 (P=0.03 and P=0.02, respectively). Indications for transplantation included congestive heart failure and/or ischemic heart disease in the majority of patients of both groups, with 83% in group 1 and 73% in group 2, respectively. In group 1, 30 patients (21%) required preoperative pharmacological support and 13 patients (9%) were on mechanical support compared with 16 (10%) and 34 (22%) patients in group 2 (P<0.01). The mean age of donors was 27±10 years and 34±13 years in groups 1 and 2, respectively (P<0.01). Major causes of mortality for donors included a motor vehicle accident in 65 cases (45%) and brain hemorrhage in 43 cases (30%) in group 1 compared with 34 cases (22%) and 68 cases (44%) in group 2 donors (P<0.01). The one-, five- and 10-year actuarial survival rates were 86%, 77% and 71%, respectively, in group 1 compared with 84%, 80% and 68%, respectively, in group 2 (P=0.95). The one-, five- and 10-year freedom from rejection rates were 35%, 28% and 25%, respectively, in group 1 compared with 41%, 36% and 33%, respectively, in group 2 (P=0.13). The one-, five- and 10-year freedom from infection rates were 38%, 24% and 17%, respectively, in group 1 compared with 37%, 23% and 19%, respectively, in group 2 (P=0.72). The one- and five-year freedom from graft coronary artery disease rates were 93% and 67%, respectively, in group 1 compared with 88% and 81%, respectively, in group 2 (P<0.01). The one-, five- and 10-year cancer-free survival rates were 98%, 91% and 73%, respectively, in group 1 compared with 98%, 90% and 77%, respectively, in group 2 (P=0.76). CONCLUSIONS: Patients who underwent heart transplantation in the second decade of the investigators’ experience were older and in worse pre-operative clinical condition; the donors were also older. However, survival and event-free survival rates remained similar throughout both periods. PMID:18340393

The introduction of endourological procedures such as percutaneous nephrolithotomy and ureterorenoscopy have led to a revolution in the the management of urinary stone disease. The indications for open stone surgery have been narrowed significantly, making it a second- or third-line treatment option. To study the safety and efficacy of retroperitoneal laparoscopic pyelolithotomy in retroperitoneal renal stone. We compared the results of laparoscopic and open surgery in terms of easy accessibility, operative period, renal injuries, and early recovery. This prospective study was conducted on renal pelvic stone cases from January 2009 to February 2016 in Suchkhand Hospital, Agra, India. The study included a total of 1700 cases with the diagnosis of solitary renal pelvic stones. In group A - 850 cases - retroperitoneal laparoscopic pyelolithotomy was performed, while group B - 850 cases - underwent open pyelolithotomy. The mean operative time was less in group B than group A (74.83 min vs. 94.43 min) which was significant (p<0.001). The blood loss was less in the laparoscopic group than in the open group (63 mL vs. 103mL). There were statistically significant differences in the post-operative pain scores, and postoperative complications compared to group B (p<0.001). The mean hospital stay was less in group A (p<0.03), which was significant. Laparoscopic surgery reduces analgesic requirements, hospital stay, and blood loss. The disadvantages include the reduced working space, the cost of equipment and the availability of a trained surgeon.

Do symptomatic female office workers perform computing tasks with higher cervical postural muscle loads (in terms of higher amplitudes and less muscular rest) and more discomfort compared with asymptomatic individuals? Are these differences in postural muscle loads consistent across bilateral (typing) and unilateral (mousing) conditions? an experimental case-control study. 18 symptomatic female office workers and 21 asymptomatic female office workers. Three conditions (typing, mousing, and type-and-mouse) were performed in random order. Muscle load was measured as median amplitude and gap frequency using surface EMG of bilateral cervical erector spinae and upper trapezius. Discomfort was measured using a numerical rating scale. The case group demonstrated 4.3% (95% CI 0.1 to 8.4) higher amplitude during typing and 3.5% (95% CI 0.1 to 6.9) higher amplitude during type-and-mouse in the right cervical erector spinae compared with the control group. There was a similar difference between groups in the left cervical erector spinae which also demonstrated a 1.2 gaps/min (95% CI -2.3 to 0.0) lower frequency during typing. The case group had significantly higher discomfort during all conditions compared with the control group. The case group demonstrated higher median amplitudes and lower gap frequencies than the control group during bilateral conditions (typing and type-and-mouse) compared with unilateral conditions (mousing) for both muscle groups. There was increased amplitude and decreased muscular rest in the cervical erector spinae of office workers performing typing and mousing tasks. These findings may represent a mechanism underlying computer-related musculoskeletal disorders.

The aim of our study was to evaluate the clinical and radiographic outcomes of malseating of the acetabular liner in ceramic-on-ceramic total hip arthroplasty (THA). Outcomes for 160 ceramic-on-ceramic THAs, contributed by 116 women and 39 men, were evaluated. Clinical and radiographic measurements were obtained over a 5- to 15-year follow-up for analysis. Liner malseating was identified in 20% of cases. Outcomes for 32 cases with liner malseating (group A) were compared to outcomes for 128 joints with correct liner seating (group B). The Harris hip score at the last follow-up was 90.1 for group A and 89.6 for group B. Osteolysis was identified in 5 cases in group A (15.6%), compared to 3 cases in group B (P < .001). No significant between-group differences were identified with regard to ceramic fracture, audible squeaking, loosening of components, and revision THA. The mean annual liner wear rate was comparable between groups, 0.0045 mm/y for group A and 0.0039 mm/y for group B. The 10-year Kaplan-Meier survivorship, based on an end point of revision THA, was 100% for group A and 99.0% for group B. Over a moderate-length follow-up of 5-15 years, malseating of the acetabular liner was not associated with negative clinical outcomes or THA survivorship. Malseating did increase the incidence of osteolysis, a risk factor for adverse effects. Long-term follow-up studies are needed to fully quantify the effects of malseating of the acetabular liner.

Association of keratoconus (KC) with genetic predisposition and environmental factors has been well documented. However, no single study has investigated the possible relationship between ABO and Rh blood groups and KC. A case-control study was designed in a university hospital enrolling 214 patients with KC in the case group and equal number of age- and sex-matched healthy subjects in the control group. Primary characteristics, ABO blood group, and Rh factors were compared between the two groups. Topographic findings of KC eyes and the severity of the diseases were investigated according to the distribution of the blood groups. Blood group O and Rh(+) phenotype were most frequent in both groups. There was no significant difference between the two groups in terms of ABO blood groups or Rh factors. Mean keratometery (K), central corneal thickness, thinnest corneal thickness, flat K, steep K, sphere and cylinder, spherical equivalent, and uncorrected visual acuity were all similar between ABO blood groups and Rh(+) and Rh(-) groups. However, the best spectacle-corrected visual acuity (BCVA) had the highest value in AB blood group (0.35 ± 0.22 logMAR, P=0.005). Moreover, the blood group AB revealed the highest frequency for grade 3 KC, followed by grades 1, 2, and 4 (P=0.003). We observed no significant excess of any particular blood group among KC cases compared with healthy subjects. Except BCVA, none of the keratometric or topographic findings was significantly different between blood groups.

We evaluated the effectiveness of FEM (5-FU, Epirubicin, MMC) therapy. One hundred ten cases of liver metastasis from gastric cancer were collected from January, 1977 until June, 2001 (synchronous: 74 cases, asynchronous: 36 cases). Twenty-nine cases were H1, 20 cases were H2 and 61 cases were H3. The patients were divided into the following groups: Group A: Resection of the primary lesion and hepatic resection (n = 9); Group A1: Hepatic resection only (5 cases), Group A2: Hepatic resection and intra-arterial infusion (4 cases). Group B: Resection of the primary lesion (n = 67); Group B1: Resection of the primary lesion only (46 cases), Group B2: Intra-arterial infusion (21 cases). In Groups A2 and B2, FEM therapy was applied to A2a (3 cases) and B2a (8 cases). Non-FEM therapy was applied to A2b (1 case) and B2b (13 cases). Group C consisted of 34 cases in which resection of the primary lesion was not undertaken. Survival rates were then compared. One-year survival rates and 50% survival period for each group were as follows: Group A: 33%, 5.9 months; Group B: 22%, 4.8 months; and Group C: 6%, 3.9 months, respectively. Five patients from Groups A2a and B2a survived for one year or longer. 1. The prognosis with liver metastasis from gastric cancer, even with a number of therapies, is not promising. 2. Resection of the primary lesion along with hepatic intra-arterial infusion therapy (in addition to hepatic resection), especially in combination with FEM therapy, provided an extended survival.

To compare the distribution of capsular groups and factor H-binding protein (fHBP) variants among meningococcal isolates and non-culture clinical specimens and to assess the representativeness of group B isolates amongst group B cases as a whole. A PCR sequencing assay was used to characterise fHBP from non-culture cases confirmed from January 2011 to December 2013. These were compared to genotypic data derived from whole genome analysis of isolates received during the same period. Group W and Y strains were more common among isolates than non-culture strains. The distribution of fHBP variants among group B non-culture cases generally reflected that seen in the corresponding isolates. Nonetheless, the non-culture subset contained a greater proportion of fHBP variant 15/B44, associated with the ST-269 cluster sublineage. Differences in capsular group and fHBP distribution among culture and non-culture cases may be indicative of variation in strain viability, diagnostic practice, disease severity and/or clinical presentation. Future analyses combining clinical case information with laboratory data may help to further explore these differences. Group B isolates provide a good representation of group B disease in E&W and, therefore, can reliably be used in fHBP strain coverage predictions of recently-licensed vaccines.

2012-01-01

Small-group case presentation exercises (CPs) were created to increase course relevance for medical students taking Medical Microbiology (MM) and Infectious Diseases (ID) METHODS: Each student received a unique paper case and had 10 minutes to review patient history, physical exam data, and laboratory data. Students then had three minutes to orally present their case and defend why they ruled in or out each of the answer choices provided, followed by an additional three minutes to answer questions. Exam scores differed significantly between students who received the traditional lecture-laboratory curriculum (Group I) and students who participated in the CPs (Group II). In MM, median unit exam and final exam scores for Group I students were 84.4% and 77.8%, compared to 86.0% and 82.2% for Group II students (P<0.018; P<0.001; Mann-Whitney Rank Sum Test). Median unit and final ID exam scores for Group I students were 84.0% and 80.0%, compared to 88.0% and 86.7% for Group II students (P<0.001; P<0.001). Students felt that the CPs improved their critical thinking and presentation skills and helped to prepare them as future physicians.

Medical simulation has been used to teach critical illness in a variety of settings. This study examined the effect of didactic lectures compared with simulated case scenario in a medical simulation course on the early management of severe sepsis. A prospective multicentre randomised study was performed enrolling resident physicians in emergency medicine from four hospitals in Asia. Participants were randomly assigned to a course that included didactic lectures followed by a skills workshop and simulated case scenario (lecture-first) or to a course that included a skills workshop and simulated case scenario followed by didactic lectures (simulation-first). A pre-test was given to the participants at the beginning of the course, post-test 1 was given after the didactic lectures or simulated case scenario depending on the study group assignment, then a final post-test 2 was given at the end of the course. Performance on the simulated case scenario was evaluated with a performance task checklist. 98 participants were enrolled in the study. Post-test 2 scores were significantly higher than pre-test scores in all participants (80.8 ± 12.0% vs 65.4 ± 12.2%, p<0.01). There was no difference in pre-test scores between the two study groups. The lecture-first group had significantly higher post-test 1 scores than the simulation-first group (78.8 ± 10.6% vs 71.6 ± 12.6%, p<0.01). There was no difference in post-test 2 scores between the two groups. The simulated case scenario task performance completion was 90.8% (95% CI 86.6% to 95.0%) in the lecture-first group compared with 83.8% (95% CI 79.5% to 88.1%) in the simulation-first group (p=0.02). A medical simulation course can improve resident physician knowledge in the early management of severe sepsis. Such a course should include a comprehensive curriculum that includes didactic lectures followed by simulation experience.

Cardiovascular implantable electronic device (CIED) infections are associated with morbidity and mortality. Peri-operative systemic intravenous antibiotic prophylaxis reduces the rate of CIED infections. AIGIS Rx , a polymer envelope implanted with the CIED, releases minocycline and rifampin, and has been introduced to reduce infections. Retrospective review of 184 patients who underwent CIED implantation was conducted. Ninety-two patients were implanted with an AIGIS Rx envelope (AIGIS Rx group) and 92 patients were not implanted with an AIGIS Rx envelope (control group). Data were collected on demographics and risk factors for CIED infections (i.e. congestive heart failure, renal insufficiency, chronic kidney disease, oral anticoagulant use, chronic steroid use, need for lead replacement or revision, temporary pacing, early re-intervention, and having more than two leads in place). Rates of implantation success, major infections and mortality were compared between the AIGIS Rx group and the control group. The AIGIS Rx group had longer hospitalizations (6.8±10.7 days vs 3.1±5.2 days; P=0.001), higher chronic corticosteroid use, higher rates of replacement or revision (51.1% vs 8.7%; P=0.001), and a greater proportion of devices with more than two intracardiac leads (42.4% vs 29.3%; P=0.03) than the control group. Successful implantation occurred in 97% of patients in both groups. Major infection was seen in 5.4% of cases in the AIGIS Rx group and 1.1% of cases in the control group (P=0.048). Device removal was conducted in 3.3% of cases in the AIGIS Rx group compared with 1.1% of cases in the control group (P=0.16). There were two deaths in the AIGIS Rx group. Organisms cultured were meticillin-resistant Staphylococcus aureus, meticillin-susceptible S. aureus and Enterococcus faecalis. The AIGIS Rx group had higher rates of major infection but also higher risk factors compared with the control group. The rate of device extraction and CIED-related mortality was higher in the AIGIS Rx group than in the control group. Copyright © 2017 The Healthcare Infection Society. Published by Elsevier Ltd.

Aims and Objectives. The aim of this study was to evaluate the effectiveness of vein conduit in nerve repair compared with isolated nerve graft. Materials and Methods. This retrospective study was conducted at author's centre and included a total of 40 patients. All the patients had nerve defect of more than 3 cm and underwent nerve repair using nerve graft from sural nerve. In 20 cases, vein conduit (study group) was used whereas no conduit was used in other 20 cases. Patients were followed up for 2 years at the intervals of 3 months. Results. Patients had varying degree of recovery. Sensations reached to all the digits at 1 year in study groups compared to 18 months in control group. At the end of second year, 84% patients of the study group achieved 2-point discrimination of <10 mm compared to 60% only in control group. In terms of motor recovery, 82% patients achieved satisfactory hand function in study group compared to 56% in control group (P < .05). Conclusions. It was concluded that the use of vein conduit in peripheral nerve repair is more effective method than isolated nerve graft providing good sensory and motor recovery. PMID:25405029

Chronic exposure to n-hexane can lead to peripheral neuropathy that no effective treatment regimen could be applied presently. This study investigated whether myelin protein zero (P0) protein and its antibody could be used to distinguish n-hexane intoxication and protect workers from peripheral neuropathy. We compared P0 protein and its antibody among three levels of n-hexane-exposed groups, which included 18 patients with n-hexane-induced peripheral neuropathy as case group, 120 n-hexane-exposed workers as n-hexaneexposed control group, and 147 non-hexane-exposed participants used as control group. ELISA method was applied to detect P0 protein and its antibody. P0 protein in serum was significantly higher in the case group and n-hexane-exposed control group in comparison with the control group (P < 0.01). Compared with the n-hexane-exposed control group, the case group also had significant increase of P0 protein (P < 0.01). After 6 months therapy, P0 protein was observed to decrease significantly in the case group (P < 0.01). The P0 antibody in serum was significantly higher in the n-hexane-exposed control group than in the control group (P < 0.01), but not significantly different between cases and controls. P0 antibodies in serum may be a short-term effect biomarker for n-hexane exposure. P0 protein in serum may be an early effective biomarker for peripheral nerve neuropathy and its biological limit value needs investigation in the future study.

We evaluated the effectiveness of FEM (5-FU, epirubicin, MMC) therapy. Data for 111 patients with liver metastasis from gastric cancer were collected from January 1977, until June 2003 (synchronous: 74 cases, asynchronous: 37 cases). Thirty patients were H1, 20 were H2 and 61 were classified as H3. The patients were divided into the following groups: Group A: Resection of the primary lesion and hepatic resection (n = 10), Group A1: Hepatic resection only (5 cases), Group A2: Hepatic resection and intraarterial infusion (5 cases). Group B: Resection of the primary lesion (n = 67), Group B1: Resection of the primary lesion only (46 cases), Group B2: Intraarterial infusion (21 cases). In Groups A2 and B2, FEM therapy was applied to A2a (4 cases) and B2a (8 cases). Non-FEM therapy was applied to A2b (1 case) and B2b (13 cases). Group C consisted of 34 cases in which resection of the primary lesion was not undertaken. Survival rates were then compared. 1-year survival rates and 50% survival period for each group were as follows: Group A: 33%, 5.9 months; Group B: 22%. 4.8 months; and Group C: 6%, 3.9 months, respectively. One case from Group A2a and 2 cases from Group B2a have survived for 3 years or longer. 1) We treated 3 patients with liver metastasis from gastric cancer who survived for 3 years or longer. 2) Resection of the primary lesion along with hepatic intraarterial infusion therapy (in addition to hepatic resection), especially in combination with FEM therapy, provided an extended length of survival.

Pulmonary fat embolism is a life-threatening event that may result to potentially determining right ventricular failure. Even if the pathophysiology of this phenomenon has been widely investigated, no immunohistochemical demonstration of right ventricular failure following pulmonary fat embolism has been reported till now. We performed an immunohistochemical investigation with the markers fibronectin and C5b-9 in 21 cases of polytrauma with bone fractures (study group-nine females and 12 males; mean age 64.6 years) compared to a control group of 21 forensic cases with various causes of death (nine females and 12 males; mean age 68.6 years). In each case at least one tissue slide from both cardiac ventricles (free wall of the right ventricle, anterior and/or posterior wall of the left ventricle) was available. The reactions were semi-quantitatively classified, and the two groups were compared. In the study group, the occurrence of ischemic changes at the right ventricle was significantly higher than in controls. The determining aspect, however, seems to be the prevalent ischemic lesion at the right ventricle compared to the left one. This may indicate the primary involvement of the right ventricle, thus, demonstrating a right ventricular failure.

Veterans with posttraumatic stress disorder (PTSD) presenting for care with Veterans Affairs Health Care System (VA) tend not to engage in evidence-based psychotherapies (EBPs) despite widespread availability of these treatments. Though there is little evidence that "readiness for treatment" affects treatment choice, many VA providers believe that interventions to increase readiness would be helpful. This naturalistic study examined the effects of a 4-session education/treatment-planning group on treatment choice among veterans in a VA outpatient PTSD treatment program. Treatment choices and completion rates of 114 veterans who received at least 1 session of the group (EG) were compared with those of 68 veterans who did not receive the group and received PTSD program treatment as usual (TAU). TAU and EG cases were matched on gender and service era. Of 114 EG cases, 52 (45.6%) chose to receive EBPs, compared with 10 of 68 TAU cases (14.7%). These rates were significantly different, χ2(1) = 18.1, p < .0001. Among cases choosing EBPs, 52.2% of EG cases completed the EBPs as planned, compared with 60% of TAU cases. These percentages were not significantly different. Among EG cases choosing EBPs, lower likelihood of treatment completion was related to psychiatric medication prescription, presence of PTSD service connection, and higher overall service-connection level. The education/treatment-planning group was associated with higher likelihood of selecting but not completing EBPs for PTSD. The decision to engage in trauma-focused treatment may be a different process from the decision to complete such treatment. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Scrutiny from the federal government and the media regarding the safety of 1 surgeon doing cases in 2 operating rooms (ORs) on the same day, prompted us to examine our own institutional data. Over the past 11 years, surgeons at our facility have operated consecutively in 1 OR on a given day or used 2 alternating ORs. This study compares these cases with a focus on revisions and complications in both groups. Six surgeons performed a total of 16,916 primary hip and knee arthroplasties from 2006-2016. 7002 cases (41%) were consecutive cases (CCs) and 9914 cases (59%) were overlapping cases (OCs). Intraoperative complications, component revisions, and postoperative complications within 90 days of surgery were compared between the CC and OC groups. There was no difference in intraoperative complication rates between the two groups (CC 1.6% vs. OC 1.7%, relative risk 1.082, 95% confidence interval 0.852 to 1.375, P = .52). There was no difference in 90-day component revision rates among the CC and OC groups (0.66% vs. 0.85% respectively, relative risk = 1.290, 95% confidence interval 0.901 to 1.845, P = .19). There was also no difference in 90-day complication rates among the CC and OC groups (1.33% vs. 1.45% respectively, relative risk = 1.094, 95% confidence interval 0.844 to 1.417, P = .54). This large study of a single institution with multiple surgeons over an 11-year period shows no compromise in patient safety or outcomes when comparing cases done in either consecutive or overlapping rooms.

By means of a mailed questionnaire, the investigators examined the incidence of cancer among 2282 former college students in whom heterophile-positive infectious mononucleosis (IM) was diagnosed between 1949 and 1969 at five U.S. universities. Cancer incidence among these IM cases was compared both with national incidence rates and with an age and sex-matched group of 2779 non-IM students. No significant increase in cancer incidence was found. Three cases of Hodgkin's disease (HD) had occurred in the IM group (1.3 cases expected) and one case in the control group. All three post-IM cases of HD were in males. Intervals between diagnoses of IM and HD were three, four, and seven years, respectively. Only two other cases of lymphoma or leukemia were observed, and both were in the control group.

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.

Paget's disease of bone (PDB) may lead to hearing loss. The present study was conducted with the aim of measuring, characterizing and determining the risk factors for hearing loss in a group of subjects with PDB. An observational, transversal, case-control study was conducted, a cohort of 76 subjects diagnosed with PDB in the case group and a control group of 134 subjects were included. Clinical, demographic and audiometric data were analysed. The comparative analysis between the subjects in the PDB group and the control group found that the case group showed higher hearing thresholds (39,51dB) compared with the control group (37.28dB) (P=.069) and presented a greater rate of conductive hearing loss (22.76%) than the control group (12.05%) (P=.0062). The study of risk factors for hearing loss found that skull involvement in bone scintigraphy, age and high blood pressure were risk factors for higher impairment in PDB. The subjects with PDB showed more profound and a higher proportion of conductive hearing loss than the control group. The patients with PDB and skull involvement presented a more severe hearing loss compared with the subjects without skull involvement. Skull involvement and age were found to be risk factors for hearing loss. Copyright © 2018 Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello.

The aim of this study was to determine the necessity of endoscopy in cases in which a corrosive substance was ingested and to find a practical way to avoid unnecessary endoscopies for similar cases in the future. The clinical records of 458 hospitalized cases with clinical histories of corrosive substance ingestion between January 2007 and December 2013 were retrospectively reviewed. The demographics of the cases, the ingested substances, and the rigid endoscopy findings were evaluated. The three most commonly ingested corrosive agents were household bleach (22.9%), household degreaser (15.9%), and drain cleaner (13.1%). Rigid esophagoscopy was performed in 367 of the 458 cases. Corrosive agents were grouped according to their purpose of household use; eight groups were created. The degree of corrosive injury observed in the different groups was compared with the degree of injury caused by household bleach. Among the corrosive agent groups, dishwashing machine products (Gr.1), laundry products (Gr.2), liquid cleaners (Gr.3), and household bleach (Gr.4) did not cause high-grade injuries. The resulting injuries and esophagoscopy results among the above groups, whether symptomatic or not, did not differ from one another. Corrosive agents such as drain cleaner (Gr.6), household degreaser (Gr.7), and several other acidic products (Gr.8) caused high-grade injuries in the esophagus; however, lime remover/HCl (Gr.5) did not. Thus, hospitalization and rigid endoscopy seem unnecessary to assess esophageal injury in most cases, if the ingested corrosive agent fits into group 1, 2, 3, or 4 and if the patient can be easily fed. Esophagoscopy is useful to shorten the hospitalization times in cases where strong corrosive agents were ingested, such as those in groups 5, 6, 7, and 8. © 2016 International Society for Diseases of the Esophagus.

To evaluate risk factors associated with maternal bacteremia in febrile peripartum women. We performed a case-control study of women with fevers occurring between 7 days before and up to 42 days after delivery of viable neonates at two academic hospitals. Women with positive blood cultures were matched with the next two febrile women meeting inclusion criteria with negative blood cultures in the microbiology data without other matching parameters. We compared maternal and neonatal characteristics and outcomes between women in the case group and those in the control group with univariate analysis. We then used logistic regression to examine the association between clinical characteristics and maternal bacteremia. After excluding blood cultures positive only for contaminants, we compared 115 women in the case group with 285 in the control group. Bacteremic women were more likely to experience their initial fever during labor (40.9% compared with 22.8%, P<.01) and more likely to have fever at or above 102°F (62.6% compared with 31.6%, P<.01). These associations persisted in the adjusted analysis: multiparity (adjusted odds ratio [OR] 1.75, 95% CI 1.07-2.87), initial fever during labor (adjusted OR 2.82, 95% CI 1.70-4.70), and fever at or above 102°F (adjusted OR 3.83, 95% CI 2.37-6.19). In an analysis restricted to neonates whose mothers had initial fevers before or in the immediate 24 hours after delivery, neonates born to women in the case group had higher rates of bacteremia compared with those born to women in the control group (9.0% compared with 1.3%, P<.01). Eight of the nine bacteremic neonates born to bacteremic mothers (89%) grew the same organism as his or her mother in blood culture. Maternal bacteremia is associated with multiparity, initial fever during labor, and fever at or above 102°F; however, 37.5% of cases of bacteremia occurred in women with maximum fevers below this threshold. Obstetricians should maintain a heightened suspicion for an infectious source of fever in women with these clinical characteristics.

Constipation is a frequent complication in paediatrics. Most of the constipation is functional. Functional constipation constitutes 25% of visits in paediatric gastroenterology clinics. Two studies were published regarding aggregation or clustering of functional constipation. Only one of these research projects was about a paediatric population. To elucidate the cluster pattern of constipation among the families of children with constipation. This case-control study was carried out on the families of 37 children < 18 years old with chronic functional constipation and the families of 37 healthy children as controls. Cases were enrolled in the study according to Rome III criteria for constipation. The control group was selected from children < 18 years old who visited the well baby clinic of the university. Parents and siblings were evaluated regarding constipation. Rome II and III were used for evaluation of constipation for adults and children, respectively. Data was analysed using SPSS (Chicago, IL, USA). The χ(2) and t-test were used for comparison. Physical activity and vegetable consumption were seen more frequently in the control group compared to the cases, but these differences were statistically insignificant. Constipation in mothers was significantly higher in the case group compared to the control group (p = 0.015). There was no significant difference between the two groups regarding exercise and vegetable consumption. The frequency of constipation among mothers was significantly higher in the case group compared to the control group. Another study is recommended in a larger population for evaluation of genetic background, diet, physical activity, and familial clustering among mothers of children with constipation.

In order to provide a scientific basis for rational use of antibiotics, we studied and compared the therapeutic effects of step-down and step-up antibiotic treatment schemes in children with lobar pneumonia. Eighty cases of children with lobar pneumonia were enrolled in this study and were randomly divided into two groups: The observation group and the control group, with 40 cases in each group. In the observation group, there were 23 cases with mild and 17 cases with severe lobar pneumonia, and in the control group, 25 were mild and 15 were severe cases. Patients in the control group were treated with antibiotics using step-up therapy method, while patients in the observation group were treated using step-down antibiotic therapy. Our results showed no significant differences in white blood cell (WBC) reduction rate, the course of antibiotic treatment, disappearance time of pulmonary rales and total efficiency in children with mild lobar pneumonia in the observation group after 72 h of treatment. The level of high-sensitivity C-reactive protein (hs-CRP) and procalcitonin (PCT) in the observation group were significantly lower. After 72 h of treatment of children with severe lobar pneumonia in the observation group, the rate of WBC reduction accelerated significantly. Compared to the patients in the control group, the course of antibiotic treatment and disappearance time of pulmonary rales were shortened significantly, while the total efficiency of treatment was improved considerably in the observation group. Also in the observation group, hs-CRP and PCT levels were significantly lower than that in the control group. In severe cases, step-down therapy showed a better result in relieving the inflammatory reactions. The disappearance time of pulmonary rales and the effective rate of treatment was significantly higher than those of step-up therapy. It was obvious that for children with severe lobar pneumonia, step-down therapy produced better results in relieving the inflammatory reaction.

Introduction Technology and market forces are driving the demand for cancer risk assessment services in the community setting, where few clinicians are trained to order and interpret predictive genetic tests. City of Hope conducts a three-phase course in genetic cancer risk assessment (GCRA) for community-based clinicians, comprised of distance didactics, face-to-face workshops and 12 months of professional development. As designed, the course cannot meet increasing demands for GCRA training. Action research identified face-to-face workshops as a barrier to increasing course capacity. This study compared the learning effectiveness of Web-based case conferencing to face-to-face training. Methods A quasi-experimental design compared pre-post knowledge, skills and professional self-efficacy outcomes from 2009-2010 course cohorts (n=96). The intervention group (n=52) engaged in Web-based case conferences during distance learning; the comparison group (n=44) participated in the course as originally designed. Results Both groups and all practice disciplines demonstrated significant pre-to-post increases on all measures. Knowledge increases were higher for the intervention group (p < .015); skills and self-efficacy increases were comparable between groups (p < .33 and p < .30, respectively). Discussion Findings support the learning utility of Web-based case conferencing. Further studies may inform the development of tools to assess the impact of Web-based case conferencing on practice change and patient outcomes, in alignment with the highest standards of continuing professional development.

To assess the clinical significance of flexible endoscopic realignment in the treatment of posterior urethral disruption in comparison to the traditional open realignment method. A total of 58 patients suffering posterior urethral disruption were enrolled into the current study from January 2003 to May 2009. Of them, 23 patients (Group A) were treated with modified technique of urethral realignment under flexible urethroscopy and 35 patients (Group B) received conventional open realignment. Either procedure was successfully performed in both groups. However, the operation time was significantly shorter in Group A (29.1 ± 9.5 min) than that in Group B (58.1 ± 11.2 min, p < 0.001). Also, patients in Group A had a significantly decreased incidence of stricture (4 of 23 cases in Group A versus 15 of 35 cases in Group B, p = 0.043) and formation of false urethra (0 of 23 cases in Group A versus 7 of 35 cases in Group B, p = 0.035). Prevalence of secondary urethroplasty was less in Group A (1/23) compared to Group B (8/35), but there was no statistical difference (p = 0.057). In addition, there was no significant difference in morbidity of urinary infection, incidence of incontinence, and impotence between the two groups (p > 0.05). Compared to the traditional open realignment, the new technique of urethral realignment under flexible endoscope has the advantage of short operation time, minimally invasive and less complications.

2018-01-01

Background The introduction of endourological procedures such as percutaneous nephrolithotomy and ureterorenoscopy have led to a revolution in the the management of urinary stone disease. The indications for open stone surgery have been narrowed significantly, making it a second- or third-line treatment option. Aims and Objectives To study the safety and efficacy of retroperitoneal laparoscopic pyelolithotomy in retroperitoneal renal stone. We compared the results of laparoscopic and open surgery in terms of easy accessibility, operative period, renal injuries, and early recovery. Methods This prospective study was conducted on renal pelvic stone cases from January 2009 to February 2016 in Suchkhand Hospital, Agra, India. The study included a total of 1700 cases with the diagnosis of solitary renal pelvic stones. In group A - 850 cases - retroperitoneal laparoscopic pyelolithotomy was performed, while group B - 850 cases – underwent open pyelolithotomy. Results The mean operative time was less in group B than group A (74.83 min vs. 94.43 min) which was significant (p<0.001). The blood loss was less in the laparoscopic group than in the open group (63 mL vs. 103mL). There were statistically significant differences in the post-operative pain scores, and postoperative complications compared to group B (p<0.001). The mean hospital stay was less in group A (p<0.03), which was significant. Conclusion Laparoscopic surgery reduces analgesic requirements, hospital stay, and blood loss. The disadvantages include the reduced working space, the cost of equipment and the availability of a trained surgeon. PMID:29440956

Urinary tract infection is the most common genitourinary disease in children so about 40% of the children with urinary tract infection suffering from reflux that caused some consequences such as pyelonephritis and kidney parenchymal injury. This research was conducted to compare the timing of voiding cystourethrogram (VCUG) in children with urinary tract infection in first week and after the first week of urinary tract infection. This research is a case-control study that both case and control groups include 208 children from 1 month to 12 years old with the complain of urinary tract infection. In case group, the VCUG was performed at the first week of infection and in control group, the VCUG was performed after the first week of infection. complication such as dysuria was observed in two-thirds of children who VCUG was performed during first week after urinary tract infection. Parents stress in case group was more than the other (P=0.015). For overall, the incidence of reflux in case and control groups was 49.5% and 50%, respectively. The mean of reflux grading in right kidney in case group was lower than control group resulting in significant differences between two groups. According to higher grade of stress in parents and complications due to VCUG at the first week of urinary tract infection, it is suggested that VCUG be conducted on selective patients in the hospital at the first week of urinary tract infection and during hospitalization.

To compare the differences in the clinical therapeutic effects on chronic knee joint pain between the combination of the central-square needling technique of thumb-tack needles with the routine therapy of acupuncture, moxibustion and tuina and the routine therapy of acupuncture, moxibustion and tuina . One hundred and twenty patients of chronic knee joint pain were randomized into an observation group and a control group, 60 cases in each one. In the control group, the routine therapy of acupuncture, moxibustion and tuina was adopted. In the observation group, at the end of treatment with the routine therapy of acupuncture, moxibustion and tuina , the subcutaneous embedding therapy was followed with four thumb-tack needles at the sites 1 to 1.5 cm above, below and bilateral to the main point ( ashi point) separately, and the needles were retained for 24 h to 48 h. The treatment was given once every two days, three times a week, totally 6 times in two weeks; and the follow-up visit was done for 3 months in patients of the two groups. The visual analogue scale (VAS) score before and after each treatment, Lequesne index score before treatment and at the end of follow-up and the case numbers of proactive use of painkillers or receiving acupuncture treatment in the follow-up stage were compared and observed in the patients of the two groups. The VAS score was reduced gradually after treatment in the patients of the two groups. The differences were significant statistically after the second treatment as compared with those before the treatment in the two groups (all P <0.05), in which, the improvements in VAS scores after the third treatment in the observation group were more obvious than those in the control group (all P <0.05). At the end of follow-up visit, Lequesne index scores were all improved as compared with those before treatment in the two groups (both P <0.05) and the improvements were similar between the two groups ( P >0.05). In the follow-up stage, there were 0 case in the observation group and 9 cases in the control group in terms of proactive use of painkillers ( P <0.05). There were 5 cases in the observation group and 1 case in the control group receiving acupuncture treatment again ( P >0.05). The acupuncture scheme in assistance with the central-square needling technique of thumb-tack needles obviously relieves chronic knee joint pain, much better sustains the analgesic effects of acupuncture and improves patient compliance.

We intended to analyze the efficacy of a new integrated cage and plate device called Perfect-C for anterior cervical discectomy and fusion (ACDF) to cure single-level cervical degenerative disc disease. We enrolled 148 patients who were subjected to single-level ACDF with one of the following three surgical devices: a Perfect-C implant (41 patients), a Zero-P implant (36 patients), or a titanium plate with a polyetheretherketone (PEEK) cage (71 patients). We conducted a retrospective study to compare the clinical and radiological results among the three groups. The length of the operation, intraoperative blood loss, and duration of hospitalization were significantly lower in the Perfect-C group than in the Zero-P and plate-with-cage groups (P < 0.05). At the last follow-up visit, heterotopic ossification (HO) was not observed in any cases (0%) in the Perfect-C and Zero-P groups but was noted in 21 cases (30%) in the plate-with-cage group. The cephalad and caudal plate-to-disc distance (PDD) and the cephalad and caudal PDD/anterior body height (ABH) were significantly greater in the Perfect-C and Zero-P groups than in the plate-with-cage group (P < 0.05). Subsidence occurred in five cases (14%) in the Perfect-C group, in nine cases (25%) in the Zero-P group, and in 15 cases (21%) in the plate-with-cage group. Fusion occurred in 37 cases (90%) in the Perfect-C group, in 31 cases (86%) in the Zero-P group, and in 68 cases (95%) in the plate-with-cage group. The Perfect-C, Zero-P, and plate-with-cage devices are effective for treating single-level cervical degenerative disc disease. However, the Perfect-C implant has many advantages over both the Zero-P implant and conventional plate-cage treatments. The Perfect-C implant was associated with shorter operation times and hospitalization durations, less blood loss, and lower subsidence rates compared with the Zero-P implant or the titanium plate with a PEEK cage.

Between December 2007 and March 2010, 69 cases of acute Achilles tendon rupture were treated by traditional open Achilles tendon anastomosis (traditional group, n=23), by minimally invasive percutaneous Achilles tendon anastomosis (minimally invasive group, n=23), and by Achilles tendon anastomosis limited incision (limited incision group, n=23). There was no significant difference in gender, age, mechanism of injury, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score between 3 groups (P > 0.05). Minimally invasive group and limited incision group were significantly better than traditional group in hospitalization days and blood loss (P < 0.01). Incision infection occurred in 2 cases of traditional group, and healing of incision by first intention was achieved in all patients of the other 2 groups, showing significant difference in the complication rate (P < 0.05). Re-rupture of Achilles tendon occurred in 1 case (4.3%) of minimally invasive group and limited incision group respectively; no re-rupture was found in traditional group (0), showing significant difference when compared with the other 2 groups (P < 0.05). All cases were followed up 12-18 months with an average of 14.9 months. The function of the joint was restored. The AOFAS score was more than 90 points in 3 groups at 12 months after operation, showing no significant difference among 3 groups (P > 0.05). The above 3 procedures can be used to treat acute Achilles tendon rupture. However, minimally invasive percutaneous Achilles tendon anastomosis and Achilles tendon anastomosis limited incision have the advantages of less invasion, good healing, short hospitalization days, and less postoperative complication, and have the disadvantage of increased risk for re-rupture of Achilles tendon after operations.

To compare the role of an aromatase inhibitor (letrozole) with a GnRH agonist (triptorelin) versus case control on the pregnancy rate and recurrence of symptoms and signs in patients with endometriosis. In a prospective randomized clinical trial, after treatment of 144 infertile women in their reproductive age by laparoscopy (whose endometriosis was confirmed by prior laparoscopy), they were divided into 3 groups: group 1 (47 cases) who received letrozole for 2 months, group 2 (40 patients) who were prescribed triptorelin for 2 months and group 3 who were 57 patients in the control group and did not receive any medication. We followed up each group at least for 12 months after their restoration of regular cycle. Pregnancy rate was 23.4% in group 1, 27.5% in group 2, and 28.1% in group 3. The results did not show significant differences among the 3 groups. Recurrence rate of endometriosis was 6.4% in group 1, 5% group 2 and 5.3% in group 3, which was not statistically significantly different as well. Pregnancy rate and endometriosis recurrence rate are comparable among the 3 groups.

We report on the results of our endovascular aneurysm repair (EVAR)-first strategy for ruptured abdominal aortic aneurysms (RAAAs) focuses on Fitzgerald classification and vein thrombosis. From 2011 to 2017, 31 patients with RAAA underwent EVAR at our hospital. We compared Fitzgerald (F)-1 patients (group A) with F-2-4 patients with obvious retroperitoneal hematoma (group B). The baseline characteristics in group A (n=9) and group B (n=22) were similar. In group B, there were 8 cases of F-2, 10 cases of F-3, and 4 cases of F-4. Of the 22 cases in group B, 16(73%) cases involved preoperative shock. Operation time was not significantly different (group A: 147 minutes, group B: 131 minutes, p = 0.48). The total mortality rate of group A and group B combined was 77.4%. The 30-day mortality was 0% for group A and 23.8% for group B, in which there were two F-4 cases and three F-3 cases. In group B, hematoma-related complications developed in six cases (deep vein thrombosis: four cases, abdominal compartment syndrome: one case, and hematoma infection: one case), and one case with deep vein thrombosis developed a pulmonary embolism that resulted in cardiac arrest. The three-year survival rate was significantly higher for group A (100% vs. 52.3%, p=0.016), but the freedom from aortic-related death rate was not significantly different (100% vs. 66.7%, p=0.056). Using EVAR for RAAA is a valid strategy. Certain complications that are associated with peritoneal hematoma, especially venous thrombosis, should receive particular attention.

Small pulmonary nodules are often difficult to identify during thoracoscopic resection, and preoperative CT-guided localization performed using either hookwire placement or methylene blue injection can be helpful. The purpose of this study is to compare the localization success and complication rates of these two techniques. One hundred two consecutive patients who underwent a total of 109 localization procedures performed with CT fluoroscopic guidance were analyzed. The procedures included 52 hookwire insertions and 57 methylene blue injections. The localization success and complication rates associated with the two groups were compared. All nodules in both groups were identified intraoperatively, except for those in two patients in the hookwire group who did not proceed to undergo same-day surgery, including one with a massive systemic air embolus that resulted in death. Hookwires were dislodged in seven of 52 cases (13%), but the surgeons were still able to locate the nodules through visualization of the parenchymal puncture sites. The total number of complications was higher in the hookwire insertion group than in the methylene blue injection group, but this trend was not statistically significant, with all types of complications occurring in 28 cases (54%) versus 26 cases (46%) (p = 0.45), major complications noted in four cases (8%) versus one case (2%) (p = 0.19), pneumothorax observed in 20 cases (38%) versus 14 cases (25%) (p = 0.15), and perilesional hemorrhage occurring in six cases (12%) versus two cases (4%) (p = 0.15), respectively. The present study suggests that methylene blue injection and hookwire insertion are statistically equivalent for preoperative pulmonary nodule localization; however, seven of 52 hookwires dislodged, and trends toward more frequent and severe complications were noted in the hookwire insertion group.

Separate-session endoscopic retrograde cholangiography (ERCP) and laparoscopic cholecystectomy (LC) is the usual method for management of inpatient choledocholithiasis. Our goal was to compare single operative-session LC and ERCP to a multi-session approach for both the same hospitalization and within 30 days after; there is limited data comparing the three groups. A retrospective review on inpatients with choledocholithiasis that underwent ERCP and LC was performed. Single operative-session ERCP + LC (SOS group) and separate hospitalization ERCP + LC (DH group) were compared against the control cohort: separate-session ERCP + LC performed during the same hospitalization (SH group). Among the 214 cases, 37 (17%) had LC + ERCP performed under a single operative session (SOS), 130 (60.7%) cases had LC + ERCP performed in separate operative sessions during the same hospitalization (SH), and 47 (22%) cases had LC + ERCP performed in different hospitalizations, within 30 days (DH). There was no statistically significant difference in efficacy or adverse events. The SOS group had a statistically significant mean shorter length of hospital stay as compared to the SH and DH groups (5.46 vs 7.15 vs 9.38; p = 0.05 and 0.02). There was a statistically significant reduction in the total cost of care in the SOS group versus the SH group ($59,221 vs $75, 808; p = 0.007). The SOS approach is safe, efficacious, and cost-efficient when compared to separate operative sessions. This approach can be considered in situations where it is preferable for the patient to undergo a single session of anesthesia, without compromising technical success and safety.

The channeling demonstration involved provision of comprehensive case management and direct service expansion. This article considers the former. Under both models, comprehensive case management was implemented largely as intended; moreover, channeling substantially increased the receipt of comprehensive care management. However, channeling was not a pure test of the effect of comprehensive case management: roughly 10-20 percent of control group members received comparable case management services. This was particularly the case for the financial control model. Thus, the demonstration was not a test of case management compared to no case management; rather, it compared channeling case management to the existing community care system, which already was providing comprehensive case management to some of the population eligible for channeling.

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.

Harp, Richard J.; Stavropoulos, S. William; Wasserstein, Alan G.

Purpose: Percutaneous hemodialysis thrombectomy causes subclinical pulmonary emboli without short-term clinical consequence; the long-term effects on the pulmonary arterial vasculature are unknown. We compared the prevalence of pulmonary hypertension between patients who underwent one or more hemodialysis access thrombectomy procedures with controls without prior thrombectomy.Methods: A retrospective case-control study was performed. Cases (n = 88) had undergone one or more hemodialysis graft thrombectomy procedures, with subsequent echocardiography during routine investigation of comorbid cardiovascular disease. Cases were compared with controls without end-stage renal disease (ESRD) (n = 100, group 1), and controls with ESRD but no prior thrombectomy procedures (n =more » 117, group 2). The presence and velocity of tricuspid regurgitation on echocardiography was used to determine the prevalence and grade of pulmonary hypertension; these were compared between cases and controls using the chi-square test and logistic regression.Results: The prevalence of pulmonary hypertension among cases was 52% (46/88), consisting of mild, moderate and severe in 26% (n = 23), 10% (n = 9) and 16% (n = 14), respectively. Prevalence of pulmonary hypertension among group 1 controls was 26% (26/100), consisting of mild, moderate and severe pulmonary hypertension in 14%, 5% and 7%, respectively. Cases had 2.7 times greater odds of having pulmonary hypertension than group 1 controls (p = 0.002). The prevalence of pulmonary hypertension among group 2 controls was 42% (49/117), consisting of mild, moderate and severe pulmonary arterial hypertension in 25% (n = 49), 10% (n = 12) and 4% (n = 5), respectively. Cases were slightly more likely to have pulmonary hypertension than group 2 controls (OR = 1.5), although this failed to reach statistical significance (p = 0.14).Conclusion: Prior hemodialysis access thrombectomy does not appear to be a risk factor for pulmonary arterial hypertension. Patients with ESRD are more likely to have pulmonary hypertension.« less

Patients undergoing femoral lengthening by external fixation tolerate treatment less well when compared to tibial lengthening. Lengthening of the femur with an intramedullary device may have advantages. We reviewed all cases of simple femoral lengthening performed at our unit from 2009 to 2014. Cases of nonunions, concurrent deformities, congenital limb deficiencies and lengthening with an unstable hip were excluded, leaving 33 cases (in 22 patients; 11 patients had bilateral procedures) for review. Healing index, implant tolerance and complications were compared. In 20 cases (15 patients) the Precice lengthening nail was used and in 13 cases (seven patients) the LRS external fixator system. The desired length was achieved in all cases in the Precice group and in 12 of 13 cases in the LRS group. The mean healing index was 31.3 days/cm in the Precice and 47.1 days/cm in the LRS group (p < 0.001). This was associated with an earlier ability to bear full weight without aids in the Precice group. There were more complications with LRS lengthening, including pin site infections and regenerate deformity. Implant tolerance and the patients' perception of the cosmetic result were better with the Precice treatment. Femoral lengthening with the Precice femoral nail achieved excellent functional results with fewer complications and greater patient satisfaction when compared with the LRS system in our patients.

Objectives To date, the relationship between C-reactive protein (CRP) level and diabetic retinopathy (DR) remains controversial. Therefore, a systematic review and meta-analysis was used to reveal the potential relationship between CRP level and DR. Methods A systematic search of PubMed, Embase.com, and Web of Science was performed to identify all comparative studies that compared the CRP level of two groups (case group and control group). We defined that diabetic patients without retinopathy and /or matched healthy persons constituted the control group, and patients with DR were the case group. Results Two cross sectional studies and twenty case control studies including a total of 3679 participants were identified. After pooling the data from all 22 studies, obvious heterogeneity existed between the studies, so a subgroup analysis and sensitivity analysis were performed. Removing the sensitivity studies, the blood CRP levels in the case group were observed to be higher than those in the control group [SMD = 0.22, 95% confidence interval (CI), 0.11–0.34], and the blood CRP levels in the proliferative diabetic retinopathy (PDR) group were also higher than those in the non-proliferative diabetic retinopathy (NPDR) group [SMD = 0.50, 95% CI, 0.30–0.70]. Conclusions The results from this current meta-analysis indicate that the CRP level might be used as a biomarker to determine the severity of DR. PMID:26636823

Biosorbable poly-L-lactide rib-connecting pins may reduce acute pain after thoracotomy.

2004-02-01

Conventional thoracotomy is currently used as a standard procedure, and is often required to treat numerous diseases. Additionally, rib resections are occasionally required to maintain an adequate field of view for surgery. The benefits of using rib pins for chest closure following such procedures have not yet been established. This study sought to evaluate the usefulness of rib pins in reducing acute postoperative pain. Thirty-three consecutive patients with lung cancer underwent lobectomies using the posterolateral approach. The patients were rib-resected and reconstructed with two techniques: 21 patients with absorbable rib pins (ARP group) and 12 patients by ligation with absorbable sutures (LAS group). Intensity of pain was assessed during the 3 days immediately following surgery. The two groups were assessed using the visual analogue scale (VAS) as a pain scale, amounts consumed of patient-controlled analgesics (PCA), and additional chest x-rays. On the first day following surgery, the mean VAS intensity of the ARP group for patient motion was 2.71 +/- 2.14, compared to 5.33 +/- 2.99 in the LAS group. After three days, the mean score for the ARP group was 1.98 +/- 1.89, compared to 4.60 +/- 1.97 in the LAS group. Scores in the ARP group were significantly lower than in the LAS group one day and three days following thoracotomy. The LAS group (55.0 +/- 15.9 times) made more frequent requests than the ARP group (16.1 +/- 10.3 times). The PCA requirement was also significantly lower in the ARP group. Excessive derangement of the rib (grade 2) was found in one case (4.7 %) in the ARP group compared to five cases (41.6 %) in the LAS group. Rib shifts were seen in numerous cases in the LAS group compared to the ARP group as measured by chest x-rays. Use of absorbable rib pins reduced postoperative pain and may improve long-term prospects for the post-thoracotomy course.

Background Small-group case presentation exercises (CPs) were created to increase course relevance for medical students taking Medical Microbiology (MM) and Infectious Diseases (ID) Methods Each student received a unique paper case and had 10 minutes to review patient history, physical exam data, and laboratory data. Students then had three minutes to orally present their case and defend why they ruled in or out each of the answer choices provided, followed by an additional three minutes to answer questions. Results Exam scores differed significantly between students who received the traditional lecture-laboratory curriculum (Group I) and students who participated in the CPs (Group II). In MM, median unit exam and final exam scores for Group I students were 84.4% and 77.8%, compared to 86.0% and 82.2% for Group II students (P<0.018; P<0.001; Mann-Whitney Rank Sum Test). Median unit and final ID exam scores for Group I students were 84.0% and 80.0%, compared to 88.0% and 86.7% for Group II students (P<0.001; P<0.001). Conclusion Students felt that the CPs improved their critical thinking and presentation skills and helped to prepare them as future physicians. PMID:22435014

This study is to estimate the effectiveness of a diabetic case management programme on health-care service utilization. The study population included 6007 as the intervention group and 956,766 as the control group. As the indicators of health-care service utilization, numbers of medical ambulatory consultations, days of medication prescribed and medical expenses for one year were used, and we analysed the claim data of the health insurance from 2005 to 2007. The study population was classified into three subgroups based on the number of medical ambulatory consultations per year before this intervention. In the under-serviced subgroup, the intervention group showed a significant increase in the number of consultations (3.2), days of prescribed medication (66.4) and medical expenses (287,900 KRW) compared with the control group. Conversely, in the over-serviced subgroup, the intervention group showed a less decrease days of prescribed medication (1.6) compared with the control group. This showed that the case management programme led the intervention group to optimize their utilization of health-care services by subgroups. It is necessary to evaluate the appropriateness of health-care usage and clinical outcome to show the direct effectiveness of the case management programme by subgroups. © 2014 Wiley Publishing Asia Pty Ltd.

To explore the effectiveness of the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments to treat acute complete acromioclavicular dislocations. Between January 2008 and April 2012, 66 patients with acromioclavicular dislocation were treated with the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments in 32 cases (experimental group) and with the clavicular hook plate in 34 cases (control group). There was no significant difference in gender, age, injured side, the cause of injury, and the time from injury to operation between 2 groups (P > 0.05). Visual analogue scale (VAS), Constant shoulder scores, and coracoid clavi-cledistance (CC. Dist) were measured at preoperation and at 2 years after operation. Signal/noise quotiem (SNQ) was measured by MRI at 2 years after operation. The operation complications were observed. The patients of 2 groups obtained primary healing of incision. The morbidity of complication in experimental group (12.5%, 4/32) was significantly lower than that in control group (91.2%, 31/34) (Χ2 = 40.96, P = 0.00). All the cases were followed up 2.8 years on average (range, 2 to 4 years). VAS scores and CC.Dist significantly decreased at 2 years after operation when compared with preoperative values in the 2 groups (P < 0.05). VAS scores and CC.Dist of the experimental group were significantly lower than those in the control group (P < 0.05). According to Constant shoulder scores at 2 years after operation, the results were excellent in 19 cases, good in 11 cases, and general in 2 cases with an excellent and good rate of 93.75% in the experimental group; the results were excellent in 7 cases, good in 8 cases, general in 16 cases, and poor in 3 cases with an excellent and good rate of 44.11% in the control group; and significant difference was shown between 2 groups (t = 2.30, P = 0.03). SNQ was significantly lower in experimental group than in control group at 2 years after operation (t = 55.03, P = 0.00), indicating that ligament healing was better in experimental group than control group. Compared with simple clavicular hook plate fixation, the clavicular hook plate combined with trapezius muscle fascia for reconstruction of acromioclavicular and coracoclavicular ligaments is successful in treating acute complete acromioclavicular dislocations, with the advantages of higher ligament healing, less complication, and early improvement of shoulder functions.

To examine the association between fetal nutritional status and overweight and obesity in their adulthood and to provide evidence for formulation of the strategy on preventing low birth weight. Using data from 2002 Nationwide Nutrition and Health Survey to set up a case-control method in order to compare body mass index(BMI), prevalence of overweight and obesity as well as to calculate odds ratio of overweight and obesity of case group compared with control group. Three case groups were selected from those who were born in 1959, 1960,1961 respectively, and the controls were those who were born in 1964. The health consequence of being famines on adulthood was evident in women. Means of BMI in women were significantly higher in three case groups than that in control group(P<0.01). After adjustment on geographic regions, the prevalence of overweight in women was significantly higher in three case groups than that in control group(P< 0.01). The prevalence rates of obesity were significantly higher in 1959, 1960 groups than 1964 group(P< 0.05). The odds ratios of overweight of women in three case groups were 28.9% (95% CI:1.063-1.565), 37.2% (95% CI:1. 136-1.658) and 35.2% (95% CI: 1. 103-1.657) respectively, all higher than that in the control group. The odds ratios of obesity of women born in 1959, 1960 groups were 46.5% (95% CI: 1.088-1.972) and 39.6% (95% CI: 1.039- 1.876) respectively, higher than that in the 1964 group. However, such differences were not found in men. Higher risks of overweight and obesity in women were caused by malnutrition during their fetal lives. A strategy on preventing low birth weight should be formulated by the government to prevent the chronic disease in adulthood.

To explore the efficacy and safety of continuously released prostaglandin E(2) (PGE(2)) suppository-propess used for induction of term pregnancy. A multicenter, prospective, case control clinical study was carried out, propess was used in 100 cases as study group, the suppository without PGE(2) was used in 49 cases as control group. The cervical maturity (by Bishop scoring), the time to labor starting, membrane rupture and delivery, the application of oxytocin, ceserean section rate, fetal and neonatal condition were compared between 2 groups after inserting of the suppository. At the same time, side effects caused by propess were investigated. Bishop score was increased >or= 2 points in 93% cases, >or= 3 points in 87% cases in study group, whereas only 4% cases whose Bishop score increased >or= 2 points in control group. The time to labor starting, membrane rupture, and delivery was shortened obviously in study group than that in control group after inserting suppository. The application of oxytocin was much less in study group, cesarean section rate was reduced in study group (32% vs 61%). There was no significant difference between 2 groups in fetal and neonatal conditions. The overstimulation of uterine contraction and mild gastrointestinal tract reaction occurred in 3 cases and 2 cases respectively in study groups. Propess can be used for induction of term pregnancy effectively and safely.

The effect of screening and treatment for abnormal vaginal flora on the reduction of preterm deliveries remains controversial. We evaluated whether this screening and treatment reduces the preterm delivery rate for general-population pregnant women. Pregnant women of the Intervention group (n = 574) underwent the screening test and the treatment of vaginal metronidazole during the early second trimester, and those of the Control group (n = 1,161) did not. We compared the preterm delivery rate between these two groups. We also compared the profiles of vaginal flora of the preterm delivery cases with those of the pregnant women with a normal course. There was no significant difference in the preterm delivery rate between these two groups. However, in the preterm delivery cases, a frequent shift to intermediate flora was observed not before but after the screening in the Intervention group. This shift may explain why most of the previous studies failed in regard to the prevention of preterm deliveries. PMID:24762852

The aim of this study was to compare the three different treatment methods and investigate The effectiveness of the therapeutic effect of common salt. This retrospective study involved patients who were treated in our clinic for umbilical pilonidal sinus disease between January 2010 and December 2011. The patients were divided to three subgroups according to treatment methods. Group I: Cases treated with only local debridement and systemic antibiotic, group II: cases treated with local debridement, systemic antibiotic and silver nitrate, group 3: cases treated with debridement, systemic antibiotic and salt. In this study, 63 patients with the diagnosis of UPS were treated in our clinic. The patients were classified into three groups; group I included 20 patients, group II included 18 patients and group III included 18 patients. During 16-24 months of follow-up, 4 (20%) recurrences in group1 and 2 (11.1%) recurrences in group 2 were detected. Recurrence rate of group 3 was significantly different (5.55%) when compared to group 2. The mean period for returning to daily activities and work was 1 day for the patients. In conclusion, we suggest that pilonidal sinus cases which are not complicated by abcess and cellulitis can be treated by local removal of umbilical hairs, debridement and dressing without surgery. We conclude that application of common salt (table/ cooking salt) to umbilical pilonidal sinus with granuloma is a simple and highly effective way of treatment without any relapse and complications.

To determine the proportion of Salmonella cases in children aged <5 years that were reptile-associated salmonellosis (RAS) and to compare the severity of illness. To analyse all cases of salmonellosis reported to public health authorities in children aged under 5 years in the South West of the UK from January 2010 to December 2013 for reptile exposure, age, serotype, hospitalisation and invasive disease. 48 of 175 (27%) Salmonella cases had exposure to reptiles. The median age of RAS cases was significantly lower than non-RAS cases (0.5 vs 1.0 year). RAS cases were 2.5 times more likely to be hospitalised (23/48) compared with non-RAS cases (25/127; p=0.0002). This trend continued in cases aged under 12 months, with significantly more RAS cases hospitalised (19/38) than non-RAS cases (8/42; p=0.003). Significantly more RAS cases had invasive disease (8/48: 5 bacteraemia, 2 meningitis, 1 colitis) than non-RAS cases (4/127: 3 bacteraemia, 1 meningitis). Reptile exposure was found in over a quarter of all reported Salmonella cases in children under 5 years of age. RAS is associated with young age, hospitalisation and invasive disease.

Intensive cognitive therapy for post-traumatic stress disorder (PTSD) has been shown to be as effective as weekly treatment in controlled trials. In this study, outcome data comparing standard and intensive treatments delivered in routine clinical practice were analysed. A consecutive case series of intensive treatment cases were compared to matched control cases who had completed weekly treatment. Both groups showed significant improvements on PTSD and depression measures. The intensive group showed larger PTSD symptomatic improvement. There were differences between the groups in age and time since trauma, suggesting selection biases in who is offered, and/or who chooses intensive treatment. For some individuals, an intensive format may be more effective than weekly treatment. © 2017 The British Psychological Society.

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.

Micronucleus Assay: An Early Diagnostic Tool to Assess Genotoxic Changes in Patients with Tobacco Use, Oral Leukoplakia and Oral Submucous Fibrosis

Introduction Micronuclei (MNi) are acentric chromatid or chromosome fragments produced via genetic damage through genotoxic agents contained in tobacco and betel nut. Evidently, the various Oral Potentially Malignant Disorders (OPMDs) like oral lichen Planus, oral leukoplakia and Oral Submucous Fibrosis (OSMF) demonstrate MNi, as a substantiation of genetic damage. As these changes can be easily appreciated in oral exfoliated cells, an exfoliated cell based MNi assay might be utilized as handy and non invasive biomonitoring tool for gauging the genetic damage and hence the propensity for malignant transformation in OPMDs. To this end, MNi are definitely easier to evaluate when compared to chromosome aberrations. Aim To compare the MNi frequency in normal mucosa, in individuals using various tobacco forms without oral leukoplakia, individuals using various tobacco forms with oral leukoplakia, and areca nut chewers with OSMF, using three different stains. Materials and Methods Oral exfoliated cells from 50 cases of normal mucosa (Group I), 50 cases of tobacco chewing people without Oral Leukoplakia (Group II), 50 cases of people with Oral Leukoplakia (Group III) and 50 cases of areca nut chewers with OSMF (Group IV) were taken. MNi frequencies were compared in these groups using three different stains i.e., Papanicolaou (PAP) stain, May Grunwald Giemsa (MGG) stain and Feulgen stain. The data between cases (Group II, III and IV) and control groups (Group I) was analyzed by Kruskal-Wallis Test. The comparison between two independent groups was done by Mann-Whitney U test and interstain comparison between cases and control was done by Wilcoxon Signed Rank Test and the individual p-value was obtained. Results A significant increase in the count was observed during transition of normal mucosa to OPMDs. The best stain for detecting MNi was PAP stain followed by MGG stain and Feulgen stain. Conclusion The higher mean MNi count for PAP stain and MGG stain could be attributed to nonspecific staining. Further study using a larger sample size on quantitative assessment of MNi count in various OPMDs is warranted. PMID:29207828

Comparison of Both Sides for Retroperitoneal Laparoscopic Donor Nephrectomy: Experience From a Single Center in China.

Laparoscopic donor nephrectomy (LDN) has gradually become the main approach to obtain live donor kidneys. However, the shorter right renal vein limits its wider application. The aim of this study was to compare the outcomes of left- and right-side retroperitoneal LDN. We reviewed the perioperative data of 527 consecutive donors receiving retroperitoneal pure LDN with a new method at our center between April 2009 and April 2014. The patients were divided into group A (the first 100 patients) and group B (the remaining 427 patients). A total of 423 cases of left donor surgery and 104 cases of right donor surgery were compared. The comparison of the laterality of LDN was also performed between group A and group B. This is currently the largest case series of LDN in our country. Although right-side LDN patients had longer operation time and a slightly higher incidence of intraoperative complications compared with left-side LDN patients, the operation time was shorter in both the groups compared with previous reports. In group B, patients undergoing right-side LDN had longer operation time and more frequent complications. Once the learning curve of 100 cases was completed, the incidence of complications and operation time were greatly reduced in both sides for LDN. There was no significant difference in the serum creatinine levels in recipients at 6 months of follow-up. Despite a slightly higher incidence of complications and longer operation time, right-side LDN can achieve equally safe and effective transplantation outcomes. This expands the source of potential donor kidneys. Copyright © 2017. Published by Elsevier Inc.

To avoid distal plaques embolization during carotid artery stenting, we developed Universal Protection Method that combined the use of a proximal common carotid artery balloon, an external carotid artery balloon, and a distal internal carotid artery filter, with continuous flow reversal to the femoral vein. Herein, we assessed the efficacy of the Universal Protection Method by comparing stenting outcomes before and after its introduction. We assessed outcomes for 115 cases before and 41 cases after the Universal Protection Method was adopted (non-Universal Protection Method and Universal Protection Method groups, respectively). We then compared procedure details, magnetic resonance imaging (within 48 hours after the procedure), intraprocedural complications, and postoperative stroke rates. Ischemic stroke was not observed in the Universal Protection Method group, but 1 major stroke and 2 minor strokes were observed in the non-Universal Protection Method group. High-intensity areas were seen in 6 (15.0%) and 49 (42.6%) cases in the Universal Protection Method and non-Universal Protection Method groups, respectively (P = .001). Contrastingly, intraprocedural complications were observed in 9 (22.5%) and 21 (18.3%) cases in the Universal Protection Method and non-Universal Protection Method groups, respectively. Among these intraprocedural complication cases, high-intensity areas were observed in 1 case (11.1%) in the Universal Protection Method group and in 15 cases (71.4%) in the non-Universal Protection Method group. Universal Protection Method is a safe technique that is applicable to all patients undergoing carotid artery stenting, irrespective of individual risk factors. Notably, the incidence rates of both distal embolization and unexpected intraprocedural complications are low. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

To determine the impact of simulation-based instruction on student performance in the role of emergency department resuscitation team leader. A randomized, single-blinded, controlled study using an intention to treat analysis. Eighty-three fourth-year medical students enrolled in an emergency medicine clerkship were randomly allocated to two groups differing only by instructional format. Each student individually completed an initial simulation case, followed by a standardized curriculum of eight cases in either group simulation or case-based group discussion format before a second individual simulation case. A remote coinvestigator measured eight objective performance end points using digital recordings of all individual simulation cases. McNemar chi2, Pearson correlation, repeated measures multivariate analysis of variance, and follow-up analysis of variance were used for statistical evaluation. Sixty-eight students (82%) completed both initial and follow-up individual simulations. Eight students were lost from the simulation group and seven from the discussion group. The mean postintervention case performance was significantly better for the students allocated to simulation instruction compared with the group discussion students for four outcomes including a decrease in mean time to (1) order an intravenous line; (2) initiate cardiac monitoring; (3) order initial laboratory tests; and (4) initiate blood pressure monitoring. Paired comparisons of each student's initial and follow-up simulations demonstrated significant improvement in the same four areas, in mean time to order an abdominal radiograph and in obtaining an allergy history. A single simulation-based teaching session significantly improved student performance as a team leader. Additional simulation sessions provided further improvement compared with instruction provided in case-based group discussion format.

The aim of the present study was to compare the gas-liquid dual support fixation and Heitzman fixation techniques for the preparation of lung specimens. A total of 40 fresh lung samples were surgically collected from 40 male patients with lung cancer by biopsy. Patients were recruited from the Affiliated Hospital of Qingdao University Medical College (Qingdao, China) between July 2007 and June 2014. Samples were prepared using either the gas-liquid dual support fixation method (group A; n=26) or the Heitzman fixation method (group B; n=14). High-resolution computed tomography (HRCT) scanning was performed prior to surgery and corresponding postoperative HRCT scanning was conducted for the lung specimens; the gross transverse specimen section, cord photography images and histological sections were evaluated. Morphological observations of lung specimens indicated that there were 22 cases in group A with grade I (84.6%) and 4 cases with grade II (15.4%), whereas, in group B, there were 5 cases with grade II (35.7%) and 9 cases with grade III (64.3%). Statistical analysis demonstrated that the grades of specimens between the two groups were significantly different (P<0.01). Results from imaging and histological studies found that the quality of lung specimens was superior in group A, compared with group B. In conclusion, the present study demonstrated that, compared with the Heitzman fixation method, gas-liquid dual support fixation may be a superior technique for the preparation of lung specimens. This finding may facilitate the improvement of lung HRCT and pathological studies. PMID:28673006

The aim of this study is to identify the effects of a case management program on knowledge about oral cancer, preventive behavior for oral cancer, and level of uncertainty for patients with oral precancerous lesions. A randomized controlled trial was conducted with two groups, using a pre- and posttest design. The experimental group received a case management program and telephone follow-up sessions; the control group received routine care. Patients were assessed at three time points: first visit to the otolaryngology clinic for biopsy examination (T0), and then at 2 weeks (T1) and 4 weeks (T2) after the biopsy examination. Patients in both groups had significantly higher levels of knowledge about oral cancer, preventive behavior for oral cancer, and lower level of uncertainty at T2 compared to T0. At T2, participants in the experimental group had significantly greater knowledge about oral cancer, more preventive behavior for oral cancer, and less uncertainty compared to those in the control group. The case management program with telephone counseling effectively improved knowledge about oral cancer, preventive behavior for oral cancer, and uncertainty levels in patients with oral precancerous lesions in the four weeks after receiving a biopsy examination. The case management program can be applied with positive results to patients receiving different types of cancer screening, including colorectal, breast, and cervical screening.

2018-04-01

The diagnostic distinction between endometrial serous carcinoma (ESC) and endometrial clear-cell carcinoma (CCC) may occasionally be problematic, and one potentially contributing factor is the finding of clear cells in otherwise classic cases of ESC. This study aimed to define the frequency of this finding and comparatively assessed the immunophenotype of the clear cells. A review of 56 cases of ESC identified 8 (14.28%) with clear cells, representing 1% to 20% (median 7.5) of tumoral volume in these cases. In only 3 cases were clear cells discernible at low (×20) magnification. There was no significant difference in stage distribution or age between ESC patients with and without clear cells. The immunophenotypes of ESC-associated clear cells (group 1) were compared with foci of conventional ESC on another tissue block within the same case (group 2; n = 8) as well as a randomly selected cohort of CCC cases (group 3; n = 8). Groups 1 and 2 showed no significant differences regarding p53, ER, PR, Napsin-A, p504S, and hepatocyte nuclear factor 1β (HNF1β) expression, or regarding mitotic indices or Ki67 proliferation rate. In contrast, group 1 cases showed an immunophenotypic profile that was notably different from that of group 3 cases, with the former showing statistically significantly higher/more frequent expression of ER, PR, Ki67, and p53 and lower/less frequent expression of Napsin-A, p504S, and HNF1β. We conclude that clear-cell change is seen in 14% of ESCs and is discernible at low magnification in only 5%; these areas show an immunophenotype that is essentially identical to the associated background conventional ESC and are phenotypically dissimilar to CCC.

To compare the perioperative outcomes of initial, consecutive robotic-assisted transabdominal preperitoneal (R-TAPP) inguinal hernia repair (IHR) cases with consecutive open cases completed by the same surgeons. Multicenter, retrospective, comparative study of perioperative results from open and robotic IHR using standard univariate and multivariate regression analyses for propensity score matched (1:1) cohorts. Seven general surgeons at six institutions contributed 602 consecutive open IHR and 652 consecutive R-TAPP IHR cases. Baseline patient characteristics in the unmatched groups were similar with the exception of previous abdominal surgery and all baseline characteristics were comparable in the matched cohorts. In matched analyses, postoperative complications prior to discharge were comparable. However, from post discharge through 30 days, fewer patients experienced complications in the R-TAPP group than in the open group [4.3% vs 7.7% (p = 0.047)]. The R-TAPP group had no reoperations post discharge through 30 days of follow-up compared with five patients (1.1%) in the open group (p = 0.062), respectively. Multivariate logistic regression analysis which demonstrated patient age > 65 years and the open approach were risk factors for complications within 30 days post discharge in the matched group [age > 65 years: odds ratio (OR) = 3.33 (95% CI 1.89, 5.87; p < 0.0001); open approach: OR = 1.89 (95% CI 1.05, 3.38; p = 0.031)]. In this matched analysis, R-TAPP provides similar postoperative complications prior to discharge and a lower rate of postoperative complications through 30 days compared to open repair. R-TAPP is a promising and reproducible approach, and may facilitate adoption of minimally invasive repairs of inguinal hernias.

The purpose of the study was to compare the outcome of revision anterior cruciate ligament (ACL) reconstruction by the double-bundle (DB) technique using multi-strand semitendinosus tendon with that of primary reconstruction by use of the same technique. The study included 21 patients who underwent revision ACL reconstruction (mean follow-up, 40 months) with the semitendinosus tendon DB technique between 1995 and 2006 and 86 unilateral primary DB ACL reconstructions (mean follow-up, 33 months) between 2000 and 2004. The outcome of both groups was compared based on differences between operated and unoperated limbs and modified International Knee Documentation Committee grades. Both the overall and sports-related subjective scores were evaluated between the 2 groups. The KT measurements (MEDmetric, San Diego, CA) averaged 1.7 mm (SD, 1.8 mm) in the revision group and 1.5 mm (SD, 1.6 mm) in the primary group. There was no significant difference in KT measurements between the 2 groups. The Lachman test was negative in 83% of revision cases and 87% of primary cases; the anterior drawer test was negative in 83% and 91%, respectively, and the pivot-shift test was negative in 78% and 90%, respectively. There was a tendency for a positive pivot-shift test in the revision group being higher. The Lysholm score and subjective recovery score were significantly lower in the revision group. The semitendinosus tendon DB revision procedure provided range of motion and anterior stability comparable to those after primary DB surgery and a comparable return to athletic activities. However, the patients tended to have positive pivot-shift test results. The revision cases were also inferior in terms of the general evaluation of recovery of knee condition. The outcome scores were lower overall in the revision group. Level IV, therapeutic case series. Copyright (c) 2010 Arthroscopy Association of North America. Published by Elsevier Inc.

The purpose of this study was to explore the effects of case-based learning on communication skills, problem-solving ability, and learning motivation in sophomore nursing students. In this prospective, quasi-experimental study, we compared the pretest and post-test scores of an experimental group and a nonequivalent, nonsynchronized control group. Both groups were selected using convenience sampling, and consisted of students enrolled in a health communication course in the fall semesters of 2011 (control group) and 2012 (experimental group) at a nursing college in Suwon, South Korea. The two courses covered the same material, but in 2011 the course was lecture-based, while in 2012, lectures were replaced by case-based learning comprising five authentic cases of patient-nurse communication. At post-test, the case-based learning group showed significantly greater communication skills, problem-solving ability, and learning motivation than the lecture-based learning group. This finding suggests that case-based learning is an effective learning and teaching method. © 2014 Wiley Publishing Asia Pty Ltd.

To compare the effect of An's Shaobei Injection ([symbols; see text]) with Xiaozhiling Injection ([symbols; see text]) in patients with internal hemorrhoids of grade I-III. This cohort study included 1,520 internal hemorrhoids patients with grade I-III who were scheduled for liquid injection treatment from July 2003 to July 2009. The cohort included patients who underwent either An's Shaobei Injection treatment (the treatment group, 760 cases) or Xiaozhiling Injection treatment (the control group, 760 cases). All patients were followed up regularly for 3 years; the observing indices included anal function recovery and clinical response after operation. Among the 1,520 patients, 1,508 (99.2%) completed the 3-year follow-up. The efficacy rate was 97.5% in the treatment group, significantly higher than the control group (91.8%, P<0.01). The recurrence rate in the treatment group was 0.5%, significantly lower than that of the control group (1.3%, P<0.01). In addition, perianal callosity occurred in 8 cases (1.1%) and anorectal stricture in 26 cases (3.5%) after operation in the control group. There was no perianal callosity and anorectal stricture in the treatment group. The treatment with An's Shaobei Injection demonstrated superior clinical effect to Xiaozhiling Injection with fewer adverse effects.

Antimicrobial exposure remains an important risk factor for developing Clostridium difficile infection (CDI). Efficient method to identify antibiotics associated with CDI is important for formulating strategies to curtail their use. As a prelude to a more extensive Agency for Healthcare Research and Quality-funded project (Evaluation & Research on Antimicrobial Stewardship's Effect on Clostridium difficile), we undertook an exploratory evaluation to determine a resource-efficient method for identifying antibiotic targets for antimicrobial stewardship interventions. The study compared a series of 6 focused case-control studies. Cases consisted of patients with laboratory-confirmed CDI admitted from July-October 2009. Controls were selected from patients without CDI hospitalized during the same period. Five groups of controls were matched to cases (2:1 ratio) using group-specific matching criteria, including admission date, age, type of admission, length of stay (LOS) to discharge, and/or LOS to CDI diagnosis. The final control group was selected from patients who received antibiotics during hospitalization. Data, including demographics and antibiotic usage, were compared between case and control groups. A total of 126 cases were matched to 6 groups of 252 controls. For control groups 1-5, the use of piperacillin and tazobactam, ceftriaxone or cefepime, ciprofloxacin or moxifloxacin, intravenous vancomycin, azithromycin, and antibiotics of last resort were significantly more frequent in case than control patients. For the final control group, the associations between ceftriaxone or cefepime, and ciprofloxacin or moxifloxacin use and CDI no longer persisted. This could in part be explained by differences in comorbidities between case and control patients even with stringent matching criteria. Use of a simple matching strategy to conduct case-control studies is an efficient and feasible compromise strategy, especially in resource-limited settings, to identify high-risk antibiotics associated with CDI.

During past decades, a connection between hepatitis and the host ABO/Rh blood groups has been always under dispute, with no appropriately designed study yet. This study aimed to investigate possible association between ABO blood/Rh groups with both hepatitis B and C. In this case-control setting, 200 healthy individuals (controls), 200 patients with chronic Hepatitis-B infection (HB) and 200 patients with chronic Hepatitis-C infection (HC) were recruited from 2010 to 2013 in Tabriz Sina Hospital. ABO blood and Rh grouping was performed and the results were compared between the case and control groups. Both pair of the control and HB groups and the control and HC groups were matched for their subjects' age and sex. In the control group, 178 subjects (89%) were Rh+ and 22 subjects (11%) were Rh-. In the HB group, there were 180 Rh+ (90%) and 20 Rh- (10%) patients. In the HC group there were 168 Rh+ (84%) and 32 Rh-negative (16%) patients. Both pair of the control and HB groups (p = 0.74), as well as the control and HC groups (p = 0.14) were comparable for the status of Rh. In the control group there were 84 (42%), 32 (16%), 66 (33%) and 18 (9%) subjects with A, B, O and AB blood groups, respectively. The corresponding figures were 84 (42%), 34 (17%), 58 (29%) and 24 (12%) for the HB patients; and 80 (40%), 29 (14.5%), 85 (42.5%) and 6 (3%) for the HC patients. Comparing between the control and HB groups showed no significant difference in terms of the frequency of ABO blood groups (p = 0.70). However, with comparing the control and HC groups, the rate of O blood group was significantly higher in the HC group and concomitantly, the rate of AB blood group was significantly higher in the control group (p = 0.04). Although, there is not a significant association between ABO blood groups and HB, this association is significant between certain ABO blood groups and HC.

To evaluate the efficacy of soluble programmed death-1 (sPD-1) for risk stratification and prediction of 28-day mortality in patients with sepsis, we compared serum sPD-1 with procalcitonin (PCT), C-reactive protein (CRP), and the Mortality in Emergency Department Sepsis (MEDS) score. A total of 60 healthy volunteers and 595 emergency department (ED) patients were recruited for this prospective cohort study. According to the severity of their condition on ED arrival, the patients were allocated to the systemic inflammatory response syndrome group (130 cases), sepsis group (276 cases), severe sepsis group (121 cases), and septic shock group (68 cases). In addition, all patients with sepsis were also divided into the survivor group (349 cases) and nonsurvivor group (116 cases) according to the 28-day outcomes. When the severity of sepsis increased, the levels of sPD-1 gradually increased. The levels of sPD-1, PCT, CRP and the MEDS score were also higher in the nonsurvivor group compared to the survivor group. Logistic regression suggested that sPD-1, PCT, and the MEDS score were independent risk factors for 28-day mortality of patients with sepsis. Area under the curve (AUC) of sPD-1, PCT and the MEDS score for 28-day mortality was 0.725, 0.693, and 0.767, respectively, and the AUC was improved when all 3 factors were combined (0.843). Serum sPD-1 is positively correlated with the severity of sepsis, and it is valuable for risk stratification of patients and prediction of 28-day mortality. Combining sPD-1 with PCT and the MEDS score improves the prognostic evaluation. Copyright © 2017 Elsevier Inc. All rights reserved.

to evaluate the characteristics regarding care of Bolivian pregnant women and their outcomes in Hospital Municipal Vereador José Storopolli. a cross-sectional retrospective case-control study comparing two groups of pregnant women from 2003 to 2007. The Study Group included 312 Bolivian pregnant women and the Control Group, 314 Brazilian women. The groups were compared with respect to demographic variables, the presence of maternal complications and perinatal outcomes. Statistical analysis was performed by χ2 test and, when necessary, by applying Yates' correction. compared to Brazilian mothers, a smaller number of Bolivian women received prenatal care (16.4 versus 5.1%, p<0.001) and among those that did, the percentage of those who had less than five visits was higher (50 versus 19.3%, p<0.001). Compared to the Brazilian group, the Bolivian group had fewer unwed mothers (12.1 versus 25.4%, p<0.001) and a lower number of nulliparous women (34.1 versus 43.6%, p=0.017). Congenital syphilis had a higher incidence in the Bolivian group (2.9 versus 0.5%, p<0.05), as well as a higher number of newborns classified as large for gestational age (14.6 versus 5.8%, p <0.001). the failure to attend prenatal care or its completion with an inadequate number of consultations, and the higher number of cases of congenital syphilis observed among the Bolivian women show the great vulnerability of this ethnic minority group to health problems. Consequently, it is necessary a strategic planning of the sectors responsible for coordinating assistance in our country, in order to reduce this disparity, either through socio-economic improvements or by the implementation of health care tailored to the needs of this group.

The prevalence of sickle cell trait is extremely high in sub-Saharan Africa. Recent studies have reported the impact of sickle cell carriers on renal function. However, data on renal abnormalities in children with sickle cell trait in this part of the world are unknown. In this report, we assess the glomerular function of children with sickle cell trait (SCT). A case control study was conducted to assess the glomerular function in 43 Congolese children with sickle cell trait (Hb-AS) matched for age to 65 children with sickle cell anemia in steady state (Hb-SS) and 67 normal controls (Hb-AA). There was a significant difference in the blood pressure levels between the Hb-AS group vs Hb-SS group (P<.05). The estimated glomerular filtration rate (eGFR) corrected for body surface area was increased in Hb-AS group compared to Hb-AA group, but there was no significant difference between the two groups (P=.48). At the same time, the eGFR was decreased, but no significantly so, in the Hb-AS group compared to the Hb-SS group (P=.19). The proportion of children with Hb-AS (16.3%) who had hyperfiltration was higher compared to the proportion (6.1%) found in the Hb-AA group, but lower compared to the proportion found in the Hb-SS group (30%). However, in both situations, the difference was not statistically significant. No case of proteinuria was detected in children with Hb-AS. It appears that at least one of six children with SCT had hyperfiltration. The findings could form a basis for further studies on this renal physiology among SCT individuals in Africa. © 2017 Wiley Periodicals, Inc.

A full range of motion after total knee arthroplasty has become more and more requested by our patients, leading to novel designs of knee implants, the so-called "hyperflex" knees. The aim of the present study was to confirm whether or not hyperflexion of operated knees really improves the patients' quality of life. A retrospective comparative case-control study has been carried out to compare clinical results shown in two types of knee prosthesis, from two homogeneous paired groups of patients including 45 cases of a "hyperflex" model (RP-F), while the control group consisted of 43 cases of a "regular design" model (Triathlon) in terms of expected postoperative flexion. The hyperflex group demonstrated significant higher mean values of passive flexion at 119.9° in the RP-F group versus 111.1° in the Triathlon group. However, global results in the "regular" control group were significantly better than the "hyperflex" study group, in both IKS knee and functional scores at 84.4 points (RP-F) vs. 89.8 points (Triathlon), and 84.6 points (RP-F) vs. 89.5 points (Triathlon), respectively. Moreover, the self-administered KOOS questionnaire was significantly in favor of the control group, with 73.5 points in RP-F knees versus 86.0 points for Triathlon knees at global KOOS postoperative scores. The quality of life of operated patients after TKA obviously would be considered as the main priority, which was better obtained by a "regular design" in our study. Hence "high flexion" cannot be considered as an absolute target when choosing a model for total knee arthroplasty.

To evaluate the efficacy and safety of a new type of titanium mesh cage (NTMC) in hybrid anterior decompression and fusion method (HDF) in treating continuously three-level cervical spondylotic myelopathy (TCSM). Ninety-four cases who had TCSM and accepted the HDF from Jan 2007 to Jan 2010 were included. Clinical and radiological outcomes were compared between cases who had the NTMC (Group A, n = 45) and traditional titanium mesh cage (TTMC, Group B, n = 49) after corpectomies. Each case accepted one polyetheretherketone cage (PEEK) after discectomy. Mean follow-up were 74.4 and 77.3 months in Group A and B, respectively (p > 0.05). Differences in cervical lordosis (CL), segmental lordosis (SL), anterior segmental height (ASH) and posterior segmental height (PSH) between two groups were not significant preoperatively, 3-days postoperatively or at final visit. However, losses of the CL, SL, ASH and PSH were all significantly larger in Group B at the final visit, so did incidences of segmental subsidence and severe subsidence. Difference in preoperative Japanese Orthopedic Association (JOA), visual analog scale (VAS), neck disability index (NDI) or SF-36 between two groups was not significant. At the final visit, fusion rate, JOA, and SF-36 were all comparable between two groups, but the VAS and NDI were both significantly greater in Group B. For cases with TCSM, HDF with the NTMC and TTMC can provide comparable radiological and clinical improvements. But application of the NTMC in HDF is of advantages in decreasing the subsidence incidence, losses of lordosis correction, VAS and NDI.

To explore and compare the effectiveness of two styles of case-based learning methods, unfolding nursing case and usual nursing case, implemented in lectures for developing nursing students' critical thinking ability. 122 undergraduate nursing students in four classes were taught the subject of medical nursing for one year. Two classes were randomly assigned as the experimental group and the other two the control group. The experimental group received the lectures presenting unfolding nursing cases and the control group was taught the usual cases. Nineteen case-based lectures were provided in 8 months in two semesters to each group. The two groups started with a similar level of critical thinking ability as tested by the instrument of Critical Thinking Disposition Inventory-Chinese version (CTDI-CV). After receiving 19 case-based learning lectures for 8 months, both groups of students significantly improved their critical thinking ability. The improvement in the experimental group was significantly higher than that in the control group (with the average total score of 303.77±15.24 vs. 288.34±13.94, p<0.05). The experimental group also had significantly better improvement in six out of seven dimensions whereas the control group showed improvement in only three out of seven dimensions of CTDI-CV. The study suggests the feasibility of implementing case-based learning in lectures. Unfolding nursing cases appear to be significantly more effective than the usual nursing cases in developing undergraduate nursing students' critical thinking ability in the subject of medical nursing. Further research can implement the unfolding nursing cases in other nursing subjects. Copyright © 2016 Elsevier Ltd. All rights reserved.

To explore visual outcomes, functional visual improvement, and events in resident-operated cataract surgery cases. Veterans Affairs Ophthalmic Surgery Outcomes Database Project across 5 Veterans Affairs Medical Centers. Retrospective data analysis of deidentified data. Cataract surgery cases with residents as primary surgeons were analyzed for logMAR corrected distance visual acuity (CDVA) and vision-related quality of life (VRQL) measured by the modified National Eye Institute Vision Function Questionnaire and 30 intraoperative and postoperative events. In some analyses, cases without events (Group A) were compared with cases with events (Group B). The study included 4221 cataract surgery cases. Preoperative to postoperative CDVA improved significantly in both groups (P < .0001), although the level of improvement was less in Group B (P = .03). A CDVA of 20/40 or better was achieved in 96.64% in Group A and 88.25% in Group B (P < .0001); however, Group B had a higher prevalence of preoperative ocular comorbidities (P < .0001). Cases with 1 or more events were associated with a higher likelihood of a postoperative CDVA worse than 20/40 (odds ratio, 3.82; 95% confidence interval, 2.92-5.05; P < .0001) than those who did not experience an event. Both groups had a significant increase in VRQL from preoperative levels (both P < .0001); however, the level of preoperative to postoperative VRQL improvement was significantly less in Group B (P < .0001). Resident-operated cases with and without events had an overall significant improvement in visual acuity and visual function compared with preoperatively, although this improvement was less marked in those that had an event.

Comparison between the risk of recurrence during pregnancy with nonpregnant periods in patients with ocular toxoplasmosis (OT). Records of 40 women were retrospectively reviewed. The women were subdivided into either a pregnant group or a control group formed by nonpregnant women during follow-up. Comparable cases from the literature were added. Mean number of recurrences per year was compared. Eleven women with pregnancies could be included. Six cases from the literature were added (total n = 17). Mean number of recurrences per year during versus not during pregnancy was 0.16 (SD 0.39) versus 0.32 (SD 0.30; p = 0.088), respectively. In the control group (n = 29) the mean number of recurrences per year (0.31; SD 0.27) was significantly higher when compared to cases during pregnant periods (p = 0.002). Adding to published series, the presented data do not provide evidence for a relevant impact of pregnancy on recurrence behavior in OT.

To compare the difference in the efficacy on post-stroke constipation between acupuncture therapy of regulating qi circulation of fe-organ and Shengxue Tongbian Capsules. Seventy-five patients of post-stroke constipation were randomized into an acupuncture group (39 cases) and a Chinese medicine group (36 cases). The unit mode comprehensive therapy of stroke was adopted as basic treatment in the two groups. In the acupuncture group, acupuncture therapy of regulating qi circulation of fu-organ was added at Tianshu (ST 25), Zhigou (TE 6), Qihai (CV 6) and Zusanli (ST 36), once every day. In the Chinese medicine group, Shengrue Tongbian Capsules were supplemented for oral administration, once every day, 10 g each time. The clinical symptom score of constipation was observed before treatment, after 1 and 2 weeks treatment in the two groups, respectively. The efficacy in 1 week and 2 weeks of treatment and the adverse reaction were observed. In 1 and 2 weeks of treatment, the clinical symptom score of constipation was reduced significantly as compared with that before treatment in the two groups (all P < 0.05). The improvements in the acupuncture group were significant than those in the Chinese medicine group in 2 weeks of treatment (8.03 +/- 2.38 vs 9.20 +/- 2.45, P < 0.05). Concerning to the occurrence of adverse reaction, there was 1 case of local bruises in needling local site in the acupuncture group; and there were 1 case of abdominal pain, 3 cases of diarrhea and 2 cases of nausea and vomiting in the Chinese medicine group. Both the acupuncture therapy of regulating qi circulation of fu-organ and Shengxue Tongbian Capsules achieve the significant efficacy on post-stroke constipation. The efficacy of the acupuncture therapy of regulating qi circulation of fe-organ is better and the adverse reaction is less after long-term persistent treatment.

To compare the efficacy and safety profiles of sorafenib and apatinib in patients with intermediate- and advanced-stage hepatocellular carcinoma (HCC). This was a single-center, retrospective study where we collected the clinical data of 72 patients, diagnosed with intermediate or advanced HCC from January 2014 to December 2016. Depending on the treatment received, 38 patients were categorized into group S (sorafenib group) and 34 into group A (apatinib group). The patients in group A received the initial recommended dose of 750 mg once daily (QD), which was reduced to 250 mg QD in the case of any class 3 or 4 adverse event (AE). Sorafenib was administered orally 400 mg twice daily (BID), and dose was modified to 400 mg or 200 mg QD in the case of grade 3 or 4 AEs. The median overall survival (OS), progression-free survival (PFS), and AEs reported in the two groups were analyzed and compared. Among the 38 patients treated with sorafenib, one patient had complete response (CR), 5 patients had partial response (PR), and 10 patients had stable disease (SD), and among the 34 patients treated with apatinib, 6 patients had PR and 7 patients had SD with no cases of CR. PFS in group S was significantly longer compared with that in group A (7.39 vs 4.79 months, respectively, P =0.031). Similar observations were made for median OS (10.4 months in group S vs 7.18 months in group A, P =0.011). However, there was no significant difference in the objective response rates (ORRs) among the study population (15.7 vs 17.6%, P =0.829). Common AEs in group S included hand and foot syndrome (HFS) and diarrhea, whereas common AEs in group A included hypertension, proteinuria, and increased transaminase. Our study showed promising clinical outcome with apatinib, but the sorafenib group exhibited better clinical efficacy with no significant difference in safety profile.

Personal experience in the treatment of 60 cases of cancer of the large bowel with left hemicolon and rectal localisation is reported. 20 manual double layer anastomoses (group I), 20 single layer (group II) and with mechanical stapler (EEA stapler) (group III) were carried out in consecutive series. The results are reported in terms of early local and general complications: specifically 13 cases of anastomotic dehiscence of which 69.2% were observed in group I, 15.4% in group II and 15.4% in group III. Total postoperative mortality was 5%, average hospitalisation was as follows: 19 days group I, 14 days group II, 17 days group III. The value of single layer anastomoses, which is comparable to results with the stapler whose use is essential in cases of real manual technical difficulty, is stressed.

In recent years, increasingly sophisticated tools have allowed for more complex robotic surgery. Robotic gastrectomy, however, is adopted in only a few selected centers. The goals of this study were to examine the adoption of robotic gastrectomy and to compare outcomes between open and robotic gastric resections. This is a case-matched analysis of patients who underwent robotic and open gastric resection performed at Sanchinarro University Hospital, Madrid from November 2011 to February 2017. Patient data were obtained retrospectively. Clinicopathologic characteristics and perioperative and postoperative outcomes were recorded and analyzed. Two groups of demographically similar patients were analyzed: the robotic group (n = 20) and the open surgery group (n = 19). The patient characteristics of the two groups have been compared. Robotic resection resulted in less blood loss, shorter postoperative hospital stay, and a longer operating time. The two groups had similar complication rates. Pathological data were similar for both procedures. Robotic gastrectomy for locally advanced gastric carcinoma is safe, and long-term outcomes are comparable to those patients who underwent open resection. Robotic gastrectomy resulted in a shorter hospital stay, less blood loss and morbidity comparable with the outcomes of open gastrectomy.

To compare the differences in the efficacy on distant version of naked eye in the patients of juvenile myopia between rotating manipulation and lifting-thrusting manipulation of acupuncture. One hundred and twenty cases (240 eyes) were randomized into a rotating manipulation group and a lifting-thrusting manipulation group, 60 cases (120 eyes) in each group. Additionally, a corrective lenses group, 60 cases (120 eyes), was set up as the control. In both manipulation groups, Cuanzhu (BL 2),Yuyao (EX-HN 4), Sizhukong (TE 23), Taiyang (EX-HN 5), Fengchi (GB 20), Zusanli (ST 36), Guangming (GB 37) and Sanyinjiao (SP 6) were punctured, but stimulated with rotating manipulation and lifting-thrusting manipulation respectively three times per week, 10 times as a treatment session and totally one session was required. In the corrective lenses group, the glasses were applied at daytime. The clinical efficacy and the changes in distant vision of naked eye before and after treatment were compared among the three groups. The total effective rate was 87.5% (105/120) in the rotating manipulation group, which was better than 69.2% (83/120) in the lifting-thrusting manipulation group (P < 0.05). The distant vision of naked eye was improved apparently in the rotating manipulation group and the lifting-thrusting manipulation group after treatment (both P < 0.05). But it was not improved in the corrective lenses group (P > 0.05). The distant vision of naked eye was improved more apparently after treatment in the rotating manipulation group as compared with that in the lifting-thrusting manipulation group (0.75 +/- 0.23 vs 0.68 +/- 0.24, P < 0.05). For 96 cases (192 eyes) with acupuncture treatment, in 3-month follow-up, 87.0% (167/192) of the cases maintained the stable vision as the original level and 13.0% (25/192) of them were reduced in the vision In the acupuncture groups, it was found that the improvement of distant vision of naked eye was more obvious after treatment with younger age, better basic vision and shorter duration of sickness (all P < 0.05). Acupuncture achieves the positive and sustainable clinical effect on juvenile myopia, and the results of rotating manipulation are superior to that of lifting-thrusting manipulation. Age, basic vision and duration of sickness impact the clinical efficacy.

Keratosis obturans (KO) and external auditory canal cholesteatoma (EACC) have been considered separate entities. While the disorders are distinct, they share many overlapping characteristics, making a correct diagnosis difficult. In the present study, we compared their clinical characteristics and radiological features to clarify the diagnostic criteria. Retrospective case series. Academic medical center. The clinical data of 23 cases of EACC and KO were retrospectively reviewed. The following clinical characteristics were compared between the 2 groups: sex, age, onset of symptoms, follow-up period, audiometric results, and imaging findings on temporal bone computed tomography including bilaterality, location, and the presence of extension to adjacent tissue. The mean age of the EACC group was significantly older than that of the KO group. All of the cases of EACC occurred unilaterally, and bilateral occurrences of KO were observed in 4 of 9 cases. All of the lesions in the KO group were circumferential, and no lesion in the EACC group invaded the superior canal wall. No significant differences in symptoms, such as acute otalgia, otorrhea, and hearing loss, were noted between the 2 groups. The incidence of conductive hearing impairment more than 10 dB was higher in the KO group than in the EACC group. Thus, KO and EACC are 2 distinct disease entities that share common features in clinical characteristics except for predominant age and bilaterality. Conservative treatment with meticulous cleaning of the lesion was successful in most cases with a long-term follow-up. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

To assess the validation of a novel control selection design by comparing the consistency between the new design and a routine design in a large case-control study that was incorporated into a nationwide mortality survey in China. A nationwide mortality study was conducted during 1989-1991. Surviving spouses or other relatives of all adults who died during 1986-1988 provided detailed information about their own as well as the deceased person's smoking history. In this study, 130,079 males who died of various smoking-related cancers at age 35 or over were taken as cases, while 103,248 male surviving spouses (same age range with cases) of women who died during the same period and 49,331 males who died from causes other than those related to smoking were used as control group 1 and control group 2, respectively. Consistency in the results when comparing cases with each of the control groups was assessed. Consistency in the results was observed in the analyses using different control groups although cancer deaths varied with region and age. Equivalence could be ascertained using a 15% criterion in most cancer deaths which had high death rates in urban areas, but they were uncertain for most cancers in rural areas irrespective of whether the hypothesis testing showed significant differences or not. Sex-matched living spouse control design as an alternative control selection for a case-control study is valid and feasible, and the basic principles of the equivalence study are also supported by epidemiological survey data.

To evaluate whether the use of a computer-aided diagnosis-contrast-enhanced spectral mammography (CAD-CESM) tool can further increase the diagnostic performance of CESM compared with that of experienced radiologists. This IRB-approved retrospective study analyzed 50 lesions described on CESM from August 2014 to December 2015. Histopathologic analyses, used as the criterion standard, revealed 24 benign and 26 malignant lesions. An expert breast radiologist manually outlined lesion boundaries on the different views. A set of morphologic and textural features were then extracted from the low-energy and recombined images. Machine-learning algorithms with feature selection were used along with statistical analysis to reduce, select, and combine features. Selected features were then used to construct a predictive model using a support vector machine (SVM) classification method in a leave-one-out-cross-validation approach. The classification performance was compared against the diagnostic predictions of 2 breast radiologists with access to the same CESM cases. Based on the SVM classification, CAD-CESM correctly identified 45 of 50 lesions in the cohort, resulting in an overall accuracy of 90%. The detection rate for the malignant group was 88% (3 false-negative cases) and 92% for the benign group (2 false-positive cases). Compared with the model, radiologist 1 had an overall accuracy of 78% and a detection rate of 92% (2 false-negative cases) for the malignant group and 62% (10 false-positive cases) for the benign group. Radiologist 2 had an overall accuracy of 86% and a detection rate of 100% for the malignant group and 71% (8 false-positive cases) for the benign group. The results of our feasibility study suggest that a CAD-CESM tool can provide complementary information to radiologists, mainly by reducing the number of false-positive findings.

No objective criteria exist to help surgeons choose between IM nailing and plate fixation for 4-part fractures of the proximal humerus. The goal of this study was to identify radiological criteria that would make one technique a better choice than the other. This was a comparative, multicentre, retrospective study of 54 cases of antegrade nailing and 53 cases of plating performed between 1st January 2009 and 31 December 2011 for 4-part fractures of the proximal humerus. All patients had a minimum radiological and clinical follow-up of 18 months. The functional outcomes were evaluated using the weighted Constant score; a poor result was defined as a weighted Constant score<70%. The following radiological criteria were evaluated during the preoperative assessment and at the last follow-up: initial displacement and reduction of humeral head and tuberosities; morphology of the medial column (i.e. calcar comminution, posteromedial hinge, size of metaphyseal head extension); occurrence of avascular necrosis (AVN). After an average follow-up of 42 months, the weighted Constant scores and rate of poor outcomes were 77% and 48% in the nail group and 81% and 38% in the plate group, respectively (ns). The humeral head was reduced into an anatomical position, valgus or varus in 57%, 30% and 13% of cases in the nail group, and 58%, 29% and 13% in the plate group, respectively. The tuberosities healed in an anatomical position in 72% of nail cases and 70% of plate cases (ns). Only the presence of a medial hinge preoperatively had an effect on the functional outcomes in the nail and plate groups: the weighted Constant scores (P=0.05) and rate of poor outcomes (P=0.02) were 82% and 52% in the nail group and 97% and 9% in the plate group, respectively. The complication rates were comparable: the rates of AVN and articular screw penetration were 17% and 11% in the nail group, and 15% and 11% in the plate group, respectively. The surgical revision rate was 18.5% in the nail group and 30% in the plate group. If the medial hinge is preserved, we recommend locking plate fixation. In other cases, either technique can be used as long as the general rules of internal fixation are applied: reduction of the tuberosities, varus correction and stabilization of the calcar area.

A fixed-prepayment system (case-based reimbursement) for patients initially requiring hospital-level care was evaluated for one year through an arrangement between a private nonprofit psychiatric hospital and a self-insured company desiring to provide psychiatric services to its employees. This clinical and financial experiment offered a means of containing costs while monitoring quality of care. A two-group, case-control study was undertaken of treatment outcomes at discharge, patient satisfaction with hospital care, and service use and costs during the program's first year. Compared with costs for patients in the control group, costs for those in the program were lower per patient and per admission; cumulative costs for patients requiring rehospitalization were also lower. However, costs for outpatient services for patients in the program were not calculated. Treatment outcomes and patients' satisfaction with hospital care were comparable for the two groups.

Triglycerides (TGs) are proatherogenic lipoproteins involving the risk of coronary heart disease (CHD), while apolipoprotein A5 (APOA5) and apolipoprotein C3 (APOC3) are main lipoproteins composing TG-rich lipoproteins. In this study, we aim to explore the correlation of CHD with APOA5 -1131 T > C and APOC3 -455 T > C single nucleotide polymorphisms (SNPs). A sum of 210 CHD patients, hospitalized between Jan. 2013 and Mar. 2015 at China-Japan Union Hospital, Jilin University, were selected as our case group and 223 healthy individuals who had physical examination at same hospital at the same period were selected as control group. The frequency distribution of genotypes of APOA5 -1131 T > C and APOC3 -455 T > C SNPs were measured by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The Stata 12.0 software was utilized for statistical analyses. There was no significant difference on age and sex between case and control group (P > 0.05). History of smoking, drinking, hypertension and diabetes mellitus, body mass index and levels of TG and fasting blood sugar in case group were shown to be higher than control group (P < 0.05), while levels of total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol in case group were lower than control group (P < 0.05). Both CC and TC' + CC frequencies of APOA5 -1131 T > C and APOC3 -455 T > C in case group were higher compared to control group (both P < 0.05). Additionally, T allele frequencies of the two SNPs in case group were lower than control group, while C allele in case group has higher frequencies compared to control group (both P < 0.05). The results of meta-analysis under allele and dominant models showed that APOA5 -1131 T > C and APOC3 -455 T > C SNPs are likely to increase the risk of CHD (both P < 0.05). APOA5 -1131 T > C and APOC3 -455 T > C SNPs may play potent roles in the development and progression of CHD.

To assess the impact of digital problem-based learning (PBL) cases on student learning in ophthalmology courses. Ninety students were randomly divided into 3 classes (30 students per class). The first class studied under a didactic model. The other 2 classes were divided into 6 groups (10 students per group) and received PBL teaching; 3 groups studied via cases presented in digital form and the others studied via paper-form cases. The results of theoretical and case analysis examinations were analyzed using the chi(2) test. Student performance on the interval practice was analyzed using the Kruskal-Wallis test. Questionnaires were used to evaluate student and facilitator perceptions. Students in the digital groups exhibited better performance in the practice procedures according to tutorial evaluations compared with the other groups (P < .05). The 2 PBL classes had significantly higher mean results of theoretical and case analysis examinations (P < .001), but there was no significant difference between the 2 PBL classes. Ninety-three percent of students in the digital groups (vs 73% in the paper groups) noted that the cases greatly stimulated their interest. Introducing PBL into ophthalmology could improve educational quality and effectiveness. Digital PBL cases stimulate interest and motivate students to further improve diagnosis and problem-handling skills.

To determine the effect of 7 days tactile kinesthetic stimulation (TKS) on preterm infants' weight and hospital stays in Khartoum State, Sudan. This is a quasi-experimental study, it was conducted in 4 hospitals between January and June 2013, Khartoum, Sudan, and it involved 160 preterm infants randomly assigned into the case and control groups (80 neonates in each). Preterm infants in the control group received routine nursing care, while preterm infants in the case group received TKS for 3 periods, 15 minute per day for 7 constitutive days, in addition to routine care. Data was collected using a structured self-designed and validated questionnaire, checklist, and weighting scale. Weight gain and hospital stay were compared between the 2 groups. Over the constitutive 7 days, the case group gained significantly more weight (1071 gm versus 1104 gm) compared with the control group (1077 gm versus 1084 gm) (1084.55±90.74) who gained only 6.9 gm within the same 7 days without TKS treatment. The mean difference in weight gain was significant (p=0.00). The hospital stay for preterm infants in the case group was significantly shorter (18.05±9.36 versus 25.47±10.25; p=0.00). Tactile kinesthetic stimulation for preterm infants has a beneficial effect on weight gain and earlier discharge from hospital, which are sequentially efficient and cost effective.

This study investigated the presence of antinuclear antibody (ANA) in older Thais compared with middle-age and younger participants. Antinuclear antibody represents the first step in the diagnostic testing for lupus erythematosus (LE) and other autoimmune diseases. Due to the lack of reference ANA levels in older, middle-age and younger Thais healthy participants, this study will be useful for determining the proper diagnostic and treatment criteria. There were 28 older (60-76 years), 17 middle-age (41-59 years) and 13 younger (24-40 years) participants in this study. Immunofluorescence was performed to analyse the ANA staining pattern and titre levels in the participants' blood samples. The presence of serum ANA was found in 18 of 28 cases (64.3%), four of 17 (23.5%) and one of 13 cases (7.7%) of the older, middle-age and younger participants, respectively. The difference in the number of serum ANA-positive participants between the older, middle-age and younger groups was statistically significant (p < 0.05). Interestingly, the ANA positive in older participants presented more than one staining pattern. The speckled pattern was the most commonly detected ANA staining pattern in the older group, being found in 12 cases followed by cytoplasmic pattern (10 cases), homogeneous pattern (nine cases) and nucleolar pattern (five cases). In the middle-age group, the speckled pattern was found in four cases, whereas one younger participant presented a nucleolar pattern. Serum ANA positive was significantly higher in the older group compared with the middle-age and younger groups. There were variations of the serum ANA staining patterns in the older group. © 2016 John Wiley & Sons A/S and The Gerodontology Association. Published by John Wiley & Sons Ltd.

Objective To assess the relative risk of amyotrophic lateral sclerosis (ALS) in families of ALS patients. Methods We conducted a cohort study based on the Swedish Multi-Generation Register (MGR) in 1961-2005. Among 6,671 probands (first ALS case in the family), 1,909 full siblings, 13,947 children, and 5,405 spouses were identified (exposed group). Other persons in MGR, who were siblings, children, or spouses to persons without ALS, served as the reference group. Relative risks of ALS among the exposed group, compared to the reference group, were calculated from Poisson regression models. Concurrence of ALS within twins was assessed in 86,441 twin pairs registered in the Swedish Twin Register. Results Nine cases of ALS were noted among the siblings and 37 cases among the children of the probands, giving a 17-fold risk among the siblings (95% confidence interval [CI], 8.1-30.4) and a 9-fold risk among the children (95% CI, 6.2-12.0), compared to the reference group. Siblings and children had a higher excess risk if the proband was diagnosed at younger age, and the excess risks decreased with increasing age at diagnosis of the proband (p < 0.001). Spouses had no significantly increased risk (p = 0.27). Two cases were identified among the co-twins of ALS probands, giving a relative risk of 32 (95% CI, 5.2-102.6). Interpretation The siblings and children of ALS patients have an around 10-fold risk of ALS compared to the reference group. The excess risks vary with both age and kinship, indicating a major genetic role in familial ALS. PMID:19670447

Objective: To analyze the relationship between directional preponderance (DP), spontaneous nystagmus(SN) and vestibular disorders, and to investigate the significance of DP in directing peripheral vestibular function in patients with vertigo. Methods: This was a retrospective analysis of 394 cases diagnosed with peripheral vestibular disease accompanied by vertigo from March 2012 to June 2014 in the Outpatient Department of the Eye & ENT Hospital of Fudan University. Results of static and dynamic posture equilibrium tests, SN, unilateral weakness(UW), and DP in videonystagmography(VNG) were analyzed and compared. Results: The mean interval time between the last vertigo attack and examination in patients with SN or DP in caloric test were 4.4 d and 7.3 d respectively, and those without SN or DP were 18.3 d and 17.5 d respectively. The patients were divided into two groups according to DP results of caloric test. DP-normal group had 203 cases and DP-abnormal group had 191 cases. Spontaneous nystagmus was presented in 44 cases in the DP-normal group (21.67%) and four in the DP-abnormal group (2.09%). A significant difference was found between the two groups (χ 2 =35.27, P =0.000). Deficiency of vestibular function was noted in 165 cases in the DP-normal group (81.28%) and 123 (64.40%) in the DP-abnormal group in static and dynamic posture equilibrium tests. The difference between the two groups was statistically significant (χ 2 =14.26, P =0.000). Conclusion: Compared with DP-normal patients, DP-abnormal patients are more likely to have spontaneous nystagmus and balance disorders due to vestibular dysfunction.

Introduction  Since the last century surgical correction of nasal septum deviation has been improved. The Universal Eclectic Technique was recently reported and there are still few studies dedicated to address this surgical approach. Objective  The objective of this study is to compare the results of septal deviation correction achieved using the Universal Eclectic Technique (UET) with those obtained through Cottle's Technique. Methods  This is a prospective study with two consecutive case series totaling 90 patients (40 women and 50 men), aged between 18 and 55 years. We divided patients into two groups according to the surgical approach. Fifty-three patients underwent septoplasty through Universal Eclectic Technique (UET) and thirty-seven patients were submitted to classical Cottle's septoplasty technique. All patients have answered the Nasal Obstruction Symptom Evaluation Scale (NOSE) questionnaire to assess pre and postoperative nasal obstruction. Results  Statistical analysis showed a significantly shorter operating time for the UET group. Nasal edema assessment performed seven days after the surgery showed a prevalence of mild edema in UET group and moderate edema in Cottle's technique group. In regard to complication rates, UET presented a single case of septal hematoma while in Cottle's technique group we observed: 02 cases of severe edemas, 01 case of incapacitating headache, and 01 complaint of nasal pain. Conclusion  The Universal Eclectic Technique (UET) has proven to be a safe and effective surgical technique with faster symptomatic improvement, low complication rates, and reduced surgical time when compared with classical Cottle's technique.

Background: Harvey-Ras (H-Ras) is an important guanosine triphosphatase protein for the regulation of cellular growth and survival. Altered Ras signaling has been observed in different types of cancer either by gene amplification and/or mutation. The H-Ras oncogene mutations are well reported, but expression of the H-Ras gene is still unknown. Objective: This study aimed to examine both protein and messenger-RNA (mRNA) expressions of H-Ras in oral squamous cell carcinoma (OSCC) and analyzed the association with risk habits and the clinicopathological profile of cases. Methodology: A total of 65 tissue specimens of OSCC (case group) and equal number of normal tissues (control group) were included in this study. H-Ras protein and mRNA expressions were analyzed using immunohistochemical and quantitative real time-polymerase chain reaction techniques, respectively. Results: The H-Ras protein was significantly overexpressed in the oral carcinoma group compared to the normal group (P = 0.03). Most of the OSCC cases showed positive staining with moderate expression, while negative and moderate staining was high in the control group. The majority of H-Ras positive cases were found in individuals with multiple risk habits including tobacco chewing. The risk of H-Ras positivity was 1.46 times higher in smokers than non-smokers. H-Ras positivity increased in cases affected with buccal mucosa site and higher grade of carcinoma. Relative mRNA level of H-Ras was significantly elevated in oral carcinoma as compared with the control group (P ≤ 0.001). Protein and mRNA levels of H-Ras in case group was poorly correlated. Conclusion: H-Ras oncogene expression was markedly higher in oral carcinoma, and it can be a prognostic marker and target for an effective molecular therapy. PMID:29731559

Paired split-plot designs of multireader multicase studies.

The widely used multireader multicase ROC study design for comparing imaging modalities is the fully crossed (FC) design: every reader reads every case of both modalities. We investigate paired split-plot (PSP) designs that may allow for reduced cost and increased flexibility compared with the FC design. In the PSP design, case images from two modalities are read by the same readers, thereby the readings are paired across modalities. However, within each modality, not every reader reads every case. Instead, both the readers and the cases are partitioned into a fixed number of groups and each group of readers reads its own group of cases-a split-plot design. Using a [Formula: see text]-statistic based variance analysis for AUC (i.e., area under the ROC curve), we show analytically that precision can be gained by the PSP design as compared with the FC design with the same number of readers and readings. Equivalently, we show that the PSP design can achieve the same statistical power as the FC design with a reduced number of readings. The trade-off for the increased precision in the PSP design is the cost of collecting a larger number of truth-verified patient cases than the FC design. This means that one can trade-off between different sources of cost and choose a least burdensome design. We provide a validation study to show the iMRMC software can be reliably used for analyzing data from both FC and PSP designs. Finally, we demonstrate the advantages of the PSP design with a reader study comparing full-field digital mammography with screen-film mammography.

To compare the efficacy difference in treatment of acute gouty arthritis between acupuncture combined with infrared irradiation and Indomethachin as well as observe the impacts on liver function. One hundred and sixty cases of gout were randomized into an acupuncture group (80 cases) and an Indomethachin group (80 cases). In acupuncture group, acupuncture was applied to Zusanli (ST 36), Sanyinjiao (SP 6), Quchi (LI 11), Xuehai (SP 10), Yanglingquan (GB 34) and Ashi points. Additionally, infrared irradiation was used in the local area. The treatment was given once daily. In Indomethachin group, Indomethachin was taken orally, 25 mg each time, three times per day. The treatment lasted for 5 days in either group. Separately, before and after treatment, pain severity and the levels of blood uric acid (BUA), erythrocyte sedimentation rate (ESR), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected. Additionally, the efficacy and the impacts on liver function were assessed. The curative rate was 52.5% (42/80) in acupuncture group, which was superior to 22.5% (18/80) in Indomethachin group (P < 0.01). In acupuncture group, the analgesia efficacy was better than that in Indomethachin group (P < 0.01) and the effect on reducing BUA and ERS levels was same as that in Indomethachin group (all P > 0.05). After treatment, ALT and AST levels had no changes in acupuncture group, but they increased apparently in Indomethachin group (all P < 0.01). Acupuncture combined with infrared irradiation achieves superior efficacy on acute gouty arthritis as compared with oral medication of Indomethachin and the therapy provides a significant effect on analgesia and does not bring the damage of liver function.

Combat-related extremity wound infections can complicate the recovery of injured military personnel. The Enterococcus genus contains both commensal and pathogenic bacteria found in many combat wounds. We describe the patient population susceptible to Enterococcus infection, the characteristics of Enterococcus spp. isolated from combat-related wounds, and the microbiological profile of Enterococcus-positive wounds. Patient and culture data were obtained from the Trauma Infectious Disease Outcomes Study. Subjects were divided into a case group with enterococcal extremity wound infections and a comparator group with wound infections caused by other micro-organisms. Case and comparator subjects had similar patterns of injury and infection. Case subjects had higher Injury Severity Scores (33 vs. 30; p < 0.001), longer hospitalization at U.S. facilities (55 vs. 40 days; p = 0.004), and required more large-volume blood transfusions (>20 units) within 24 h post-injury (53% vs. 30%; p < 0.001). Approximately 60% of case subjects had three or more infections, and 91% had one or more polymicrobial infections, compared with 43% and 50%, respectively, in the comparator group. The thigh was the most common site of Enterococcus spp. isolation, contributing 50% of isolates. Enterococcus faecium was the predominant species isolated from case-group infections overall (66%), as well as in polymicrobial infections (74%). Frequent co-colonizing microbes in polymicrobial wound infections with Enterococcus were other ESKAPE pathogens (64%) (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae [and Escherichia coli], Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.) and fungi (35%). The specific pathogenicity of Enterococcus relative to other pathogens in polymicrobial wounds is unknown. Identifying strain-specific outcomes and investigating the interactions of Enterococcus strains with other wound pathogens could provide additional tools and strategies for infection mitigation in combat-related wounds.

Transbronchial biopsy (TBB) which is performed with metal forceps (forceps TBB) has been accepted as a useful technique in establishing diagnoses of diffuse lung diseases (DLDs). The use of cryoprobes to obtain alveolar tissue (cryo-TBB) is a new method which is currently used by our institute as well as others with excellent results. To assess the safety of cryo-TBB compared with conventional forceps TBB. We performed a retrospective data evaluation of 300 consecutive patients who underwent cryo-TBB between January 2012 and April 2014 and compared them with historical cases treated with forceps TBB between 2010 and 2012. The results of both diagnostic modalities were compared based on pathological reports. The major complications (significant bleeding and pneumothorax) were compared, along with postprocedural hospitalization. Pneumothorax was observed in 15 cases (4.95%) treated with cryo-TBB versus 9 cases (3.15%) treated with forceps TBB, with no significant difference (p = 0.303). The insertion of a chest tube was necessary in 6 (2%) and 4 (1.3%) of the cases having undergone cryo-TBB or forceps TBB, respectively (p = 0.8). In the cryo-TBB group, bleeding was encountered in 16 cases (5.2%), and it occurred in 13 cases (4.5%) of the forceps TBB group, with no significant difference in rates (p = 0.706). Also, there was no significant difference in hospital admission rates between the groups [cryo-TBB: 10 (3.3%); forceps TBB: 4 (1.44%); p = 0.181]. The safety profile of cryo- and forceps TBB remained the same even when stratified according to indications for TBB, i.e. immunocompromised hosts, patients after lung transplantation and those with DLDs. In patients with DLDs, cryo-TBB is as safe as forceps TBB.

Seizures are a recognized complication of acute overdose with the racemic (1:1 ratio of R- and S-enantiomers) selective serotonin reuptake inhibitor antidepressant citalopram. We tested the hypothesis that escitalopram (the therapeutically active S-enantiomer of citalopram) causes fewer seizures in overdose than citalopram at comparable doses of the S-enantiomer. Multicenter retrospective review of cases with citalopram and escitalopram overdose reported to German, Austrian, and Swiss Poisons Centers between 1997 and 2006. 316 citalopram and 63 escitalopram cases were analyzed. Somnolence, nausea, vomiting, tachycardia, QT prolongation, and tremor occurred with similar frequency in both groups. There was a striking difference in the frequency of single and multiple seizures: 43 cases (13.5%) in the citalopram group and 1 case (1.6%) with a single seizure in the escitalopram group (p=0.0065). At comparable ingested doses of the S-enantiomer, the symptom profile for citalopram and escitalopram intoxications is similar except for seizures that occur more frequently in citalopram than in escitalopram poisoning.

We aimed to evaluate the clinical results and biocompatibility of the minimal extracorporeal circulation system (MECC) compared with off-pump coronary revascularization (OPCABG). In a prospective randomized study, 150 patients underwent coronary surgery with the use of MECC and 150 underwent OPCABG. End points were (1) circulating markers of inflammation and organ injury, (2) operative results, and (3) outcome at 1-year follow-up. Operative mortality and morbidity were comparable between the groups. Release of inflammatory markers was similar between groups at all time points (peak interleukin-6 167.2+/-13.5 versus 181+/-6.5 pg/mL, P=0.14, OPCABG versus MECC group, respectively). Peak creatine kinase was 419.3+/-103.5 versus 326+/-84.2 mg/dL (P=0.28), and peak S-100 protein was 0.13+/-0.08 versus 0.29+/-0.1 pg/mL (P=0.058, OPCABG versus MECC group, respectively). Length of hospital stay and use of blood products were similar between groups. Two cases of angina recurrence at 1 year in the MECC group were observed versus 5 cases observed in the OPCABG group (P=0.44). A residual perfusion defect at myocardial nuclear scan was less frequent among patients in the MECC group (3 versus 9 cases, P=0.14; odds ratio 0.32, 95% confidence interval 0.07 to 1.32). Six (OPCABG group) versus 3 (MECC group) coronary grafts were occluded or severely stenotic at 1 year (P=0.33, odds ratio 0.47, 95% confidence interval 0.09 to 2.14). Clinical results of coronary revascularization with MECC are optimal when this procedure is performed by experienced teams. Postoperative morbidity is comparable to that with OPCABG. MECC is associated with little pump-related systemic and organ injury. It may achieve the benefits of OPCABG (less morbidity in high-risk patients) while facilitating complete revascularization in the case of complex lesions unsuitable for OPCABG.

The aim of this study was to characterise the imaging features seen in fetuses having undergone feticide by intracardiac potassium chloride injection compared to those of non-terminated fetuses at post-mortem magnetic resonance imaging (PMMRI). A case-control study was performed comparing PMMRI findings between two groups of patients - those having undergone feticide were matched to a control group of miscarried/stillborn fetuses. The groups were matched according to gestational age, weight, and time since death. Two independent readers reviewed the PMMRI for thoracic, abdominal, and musculoskeletal imaging features. The Fishers exact test was conducted for differences between the patient groups. Twenty-six cases of feticide (mean gestation 25 weeks [20-36]) and 75 non-terminated fetuses (mean gestation 26.7 weeks [19-36]) were compared. There was a higher proportion of feticide cases demonstrating pneumothorax (23.1 vs. 1.3%, p = 0.001), haemothorax (42.3 vs. 4%, p = 0.001), pneumopericardium (30.8 vs. 5.3%, p = 0.002), and haemopericardium (34.6 vs. 0%, p = 0.0001). Intracardiac gas and intra-abdominal findings were higher in the feticide group, but the differences were not statistically significant. Characteristic PMMRI features of feticide can help improve reporter confidence in differentiating iatrogenic from physiological/pathological processes. © 2018 S. Karger AG, Basel.

Our aim is to investigate the effect of active ankle movement to prevent deep vein thrombosis (DVT) in patients who received lower limb surgery, and to provide a theory of evidence for rehabilitation nursing of patients after orthopedic surgery. Between January 2012 and December 2013, a total of 174 patients were randomized as case group (n = 96) and control group (n = 78). Case group received routine nursing and active ankle movement (30 times/min, 1-7 days after surgery), while control group only received routine nursing. The symptoms and signs of DVT were in real-time observation during the experiment. Thigh and crus circumference, maximum venous outflow (MVO), maximum venous capacity (MVC), and MVO ratio (MVO ratio = MVO/MVC) in the two groups were measured 1-7 days after surgery. Six-month follow-up study was also conducted to observe the occurrence of DVT. Our study revealed that thigh circumference in the case group decreased compared with the control group in 5-7 days (fifth day: 39.98 ± 3.25 vs. 41.01 ± 3.38, P = 0.043; sixth day: 38.21 ± 3.81 vs. 39.49 ± 3.79, P = 0.029; seventh day: 37.13 ± 3.15 vs. 38.76 ± 3.31, P = 0.001), and crus circumference in the case group also decreased compared with the control group in 5-7 days (fifth day: 26.35 ± 2.11 vs. 27.01 ± 2.19, P = 0.045; sixth day: 25.99 ± 2.31 vs. 26.88 ± 3.12, P = 0.032; seventh day: 25.56 ± 1.99 vs. 26.38 ± 2.89, P = 0.028). MVO and MVC in the case group increased compared with the control group 7 days after surgery (MVO: 15.01 ± 2.56 vs. 14.12 ± 2.56, P = 0.024; MVC: 10.18 ± 3.15 vs. 8.91 ± 2.78, P = 0.006). Significant difference in the incidence of thrombus and DVT were found between the case group and the control group 1-7 days after surgery (thrombus: 1.0% and 7.7%, P = 0.027; DVT: 7.6% and 18.4%, P = 0.032). Our result manifested that active ankle movement can relieve the swelling of patients after lower limb surgery, and improve the MVO and MVC of patients to prevent formation of DVT after lower limb surgery.

Researchers from 11 countries (Austria, England, Estonia, Finland, France, Germany, Ireland, Netherlands, Poland, Spain, and Sweden) compared how their Diagnosis-Related Group (DRG) systems deal with knee replacement cases. The study aims to assist knee surgeons and national authorities to optimize the grouping algorithm of their DRG systems. National or regional databases were used to identify hospital cases treated with a procedure of knee replacement. DRG classification algorithms and indicators of resource consumption were compared for those DRGs that together comprised at least 97 % of cases. Five standardized case scenarios were defined and quasi-prices according to national DRG-based hospital payment systems ascertained. Grouping algorithms for knee replacement vary widely across countries: they classify cases according to different variables (between one and five classification variables) into diverging numbers of DRGs (between one and five DRGs). Even the most expensive DRGs generally have a cost index below 2.00, implying that grouping algorithms do not adequately account for cases that are more than twice as costly as the index DRG. Quasi-prices for the most complex case vary between euro 4,920 in Estonia and euro 14,081 in Spain. Most European DRG systems were observed to insufficiently consider the most important determinants of resource consumption. Several countries' DRG system might be improved through the introduction of classification variables for revision of knee replacement or for the presence of complications or comorbidities. Ultimately, this would contribute to assuring adequate performance comparisons and fair hospital reimbursement on the basis of DRGs.

Background: Coronary Artery Disease is known as the main cause of death in industrialized countries. Relation between this disease and some infections such as Helicobacter pylori (H.pylori) has been shown in several studies. The purpose of this study was to dermine the relationship between Hypylori and mycardical infarctions. Methods: Seventy-three myocardial infarction patients and 78 individuals with no history of this disease were compared. Patients and control matched for age and sex person to person by the match method. Levels of serum IgA and IgG antibodies against H. pylori were measured by Elisa method. Also, cholesterol, triglyceride, LDL, HDL measured in both groups and data were compared between two groups in terms of relation with cardiac risk factors. Results: From 151 participants, 73 were patients and 78 were control subjects. The percentage of IgG positive cases against H. pylori was 57.5% in the case group and 32.1% in the control group (p=0.002, OR: 2.87 CI: 95%; 1.5-5.6). Meanwhile, there was no significant difference in IgA positive cases between the two groups (42.5% and 48.7% in the case and control groups, respectively) (p=0.44; OR: 0.78 95% CI; 0.41-1.48). The study showed 74.2% of cases in the case group and 45.2% in the control group were positive for both IgG and IgA (p=0.01; OR: 3.5 95% CI; 1.3-9.5). No significant differences were found between two groups in terms of relation between H. pylori related antibodies level and heart disease classic risk factors (smoking, hypertension,…), sex, and age, but between dyslipidemia and H. pylori related antibodies was significant differences in case group (p=0.05). Conclusion: According to the results, it seems there is a relation between H. pylori infection and myocardial infarction. Also, between dislipidemia and H. Pylori antibodies in case group were significant difference. Therefore, H. pylori can be a new risk factor for atherosclerosis or can be exacerbate effect of other risk factors. Proper diagnosis and treatment of these infections can be useful in prone patients. More studies with larger sample groups are needed to review the possible role of this pathogen as a heart disease risk factor. PMID:24024020

Structural and ultrastructural alterations in human olfactory pathways and putative associations with human herpesvirus 6 (HHV-6) infection were studied. The olfactory bulb/tract samples from 20 subjects with an unspecified encephalopathy determined by pathomorphological examination of the brain autopsy, 17 healthy age-matched and 16 younger controls were used. HHV-6 DNA was detected in 60, 29, and 19% of cases in these groups, respectively. In the whole encephalopathy group, significantly more HHV-6 positive neurons and oligodendrocytes were found in the gray matter, whereas, significantly more HHV-6 positive astrocytes, oligodendrocytes, microglia/macrophages and endothelial cells were found in the white matter. Additionally, significantly more HHV-6 positive astrocytes and, in particular, oligodendrocytes were found in the white matter when compared to the gray matter. Furthermore, when only HHV-6 PCR+ encephalopathy cases were studied, we observed similar but stronger associations between HHV-6 positive oligodendrocytes and CD68 positive cells in the white matter. Cellular alterations were additionally evidenced by anti-S100 immunostaining, demonstrating a significantly higher number of S100 positive cells in the gray matter of the whole encephalopathy group when compared to the young controls, and in the white matter when compared to both control groups. In spite the decreased S100 expression in the PCR+ encephalopathy group when compared to PCR- cases and controls, groups demonstrated significantly higher number of S100 positive cells in the white compared to the gray matter. Ultrastructural changes confirming the damage of myelin included irregularity of membranes and ballooning of paranodal loops. This study shows that among the cellular targets of the nervous system, HHV-6 most severely affects oligodendrocytes and the myelin made by them. PMID:28072884

To compare the efficacy among acupuncture based on "jin" theory, regular acupuncture and western medication. A total of 95 cases, by using incomplete randomization method, were divided into a "jin" theory acupuncture group (32 cases), a regular acupuncture group (31 cases) and a medication group (32 cases). Patients in the "jin" theory acupuncture group were treated with acupuncture based on "jin" theory which included the "gather" and "knot" points on the affected side: positive reacted points, Fengchi (GB 20), Tianrong (SI 17), Tianyou (TE16) and Yiming (EX-HN14) as the main acupoints, while the Ermen (TE 21), Tinggong (SI 19) and Tinghui (GB 2) and zhigou (TE 6) as the auxiliary acpoints; the treatment was given once a day. Patients in the regular acupuncture group were treated with regular acupuncture at Tinggong (SI 19), Tin- ghui (GB 2) and Ermen (TE 21) and other matched acupoints based on syndrome differentiation, once a day. Pa- tients in the medication group were treated with oral administration of betahistine mesylate, three times a day. Ten days of treatment were taken as one session in three groups, and totally 2 sessions were given. Visual analogue scale (VAS), tinnitus handicap inventory (THD), and tinnitus severity assessment scale (TSIS) were evaluated before and after treatment; also the clinical efficacy was compared among three groups. There are 5 drop-out cases du- ring the study. After the treatment, the VAS, THI and TSIS were improved in three groups (all P < 0.05); the VAS, THI and TSIS in the "jin" theory acupuncture group were lower than those in the regular acupuncture group and medication group (P < 0.05, P < 0.01). The total effective rate was 90.0% (27/30), 80.0% (24/30) and 63.3% (19/30), which was higher in the "jin" theory acupuncture group (P < 0.05, P < 0.01). The acupuncture based on "jin" theory is superior to regular acupuncture and western medication for cervical tinnitus.

Background The Institute of Medicine has recommended a change in the name and criteria for Chronic Fatigue Syndrome (CFS), renaming the illness Systemic Exertion Intolerance Disease (SEID). The new SEID case definition requires substantial reductions or impairments in the ability to engage in pre-illness activities, unrefreshing sleep, post-exertional malaise, and either cognitive impairment or orthostatic intolerance. Purpose In the current study, samples were generated through several different methods and were used to compare this new case definition to previous case definitions for CFS, Myalgic Encephalomyelitis (ME-ICC), Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), as well as a case definition developed through empirical methods. Methods We used a cross-sectional design with samples from tertiary care settings, a biobank sample, and other forums. 796 patients from the US, Great Britain, and Norway completed the DePaul Symptom Questionnaire. Results Findings indicated that the SEID criteria identified 88% of participants in the samples analyzed, which is comparable to the 92% that met the Fukuda criteria. The SEID case definition was compared to a four item empiric criteria, and findings indicated that the four item empiric criteria identified a smaller, more functionally limited and symptomatic group of patients. Conclusion The recently developed SEID criteria appears to identify a group comparable in size to the Fukuda et al. criteria, but a larger group of patients than the Canadian ME/CFS and ME criteria, and selects more patients who have less impairment and fewer symptoms than a four item empiric criteria.

Interprofessional (IP) care is critical for effective pain management, but evidence is lacking about the best way to teach pain management skills to medical and nursing students using IP strategies. In 2013 and 2014, 307 medical and 169 nursing students participated in an IP case-based pain management workshop. The aims of this study were to determine (1) if students who participate in IP case-based learning groups will have improved pain management skills compared to students who participate in uniprofessional case-based learning groups, and (2) if students mentored by faculty with IP training will have improved pain management skills compared to students who are not mentored by IP-trained faculty. Student learning was assessed and compared using scored checklists for each group's pain management plans. Findings show that IP mentorship and IP group participation improved medical students' pain management skills but did not have the same effect on nursing student performance. Continued work is needed to develop, refine, and integrate innovative and tailored IP strategies into the curricula of medical and nursing schools to advance the pain management competencies of students before they enter clinical practice.

Lens case contamination is a risk factor for microbial keratitis. The effectiveness of manufacturers' lens case cleaning guidelines in limiting microbial contamination has not been evaluated in vivo. This study compared the effectiveness of manufacturers' guidelines and an alternative cleaning regimen. A randomized cross-over clinical trial with two phases (n = 40) was performed. Participants used the lens types of their choice in conjunction with the provided multipurpose solution (containing polyhexamethylene biguanide) for daily wear. In the manufacturers' guideline phase, cases were rinsed with multipurpose solution and air dried. In the alternative regimen phase, cases were rubbed, rinsed with solution, tissue wiped, and air-dried face down. The duration of each phase was 1 month. Lens cases were collected at the end of each phase for microbiological investigation. The levels of microbial contamination were compared, and compliance to both regimens was assessed. The case contamination rate was 82% (32/39) in the manufacturers' guideline group, compared with 72% (28/39) in the alternative regimen group. There were significantly fewer (p = 0.004) colony forming units (CFU) of bacteria from cases used by following the alternative regimen (CFU range of 0 to 10, and median of 12 CFU per well) compared with that of the manufacturer's guidelines (CFU range of 0 to 10, and median of 28 CFU per well). The compliance level between both guidelines was not significantly different (p > 0.05). The alternative guidelines are more effective in eliminating microbial contamination from lens cases than that of the current manufacturer's guideline. Simply incorporating rubbing and tissue-wiping steps in daily case hygiene reduces viable organism contamination.

Two-year outcomes of patients with schizophrenic disorders who were assigned to an intensive, team-based case management program and patients who received standard psychiatric services were assessed. The case management model featured increased staff contact time with patients, rehabilitation plans based on patients' expressed needs, and patients' attendance at team meetings where their rehabilitation plan was discussed. Forty patients were randomly assigned to either the case management group or the control group that received standard services. Patients' use of emergency and inpatient services, their quality of life, the size of their social networks, and their relatives' burden of care were assessed at assignment to the study groups and at two-year follow-up. Patients in the case management group had significantly fewer emergency visits compared with the two years before the study, and their relatives reported significantly reduced burden of care associated with relationships with psychiatric services over the two-year period. The size of patients' social networks increased for the case management group and decreased for the control group. A team-based intensive case management model is an effective intervention in the rehabilitation of patients with chronic schizophrenia.

To observe the effects of two different therapies on patients whose cervical function were restricted due to cervical spondylotic radiculopathy. Form April 2008 to October 2009, 71 cases with cervical spondylotic radiculopathy were divided into group A (36 cases) and group B (35 cases). Among them, 22 cases were male and 49 cases were female, ranging in age form 45 to 65 years with an average of 52.27 years, course of disease was from 3 days to 5 years. The patients in group A were treated with rotation-traction manipulation, neck pain particles and cervical rehabilitation exercises; and the patients in group B were treated with cervical traction, Diclofenac sodium sustained release tablets and wearing neck collar. Theapeutic time was two weeks. The cervical anteflexion, extension, left and right lateral bending, left and right rotative activity were measured by helmet-style activities instrument before and after treatment (at the 1, 3, 5, 7, 9, 11, 13 days and 1 month after treatment respectively). There were no difference between two groups in cervical activity in all directions before treatment (P > 0.05). Compared with the beginning, cervical anteflexion and extension showed significant difference at the 5th day after treatment in group A (P < 0.01). In group B, cervical anteflexion showed significant difference at the 13th day after treatment (P < 0.05), but at the 1 month after treatment, the significant difference disappeared (P > 0.05); cervical extension showed significant difference at the 7th day after treatment compared with the beginning (P < 0.05). Compared with the beginning,left lateral bending showed significant difference at the 1st day after treatment in group A (P < 0.05) and at the 5th day after treatment in group B (P < 0.01). Both in group A or B, right lateral bending, left and right rotative activity showed significant difference at the same time after treatment, either the 3rd day (P < 0.05) or the 5th day (P < 0.05). Compared between groups, cervical anteflexion, left and right lateral bending, left and right rotative activity showed significant difference at the 1 month after treatment (P < 0.05). The rotation-traction manipulation and neck pain particles and cervical rehabilitation exercises in treating cervicalspondylotic radiculopathy have quick effect to improve the activities of cervical anteflexion, extension, left lateral bending, and have durable effect to improve the activities of cervical spine in all directions.

Background To compare extra levator abdomino perineal resection (ELAPER) with conventional abdominoperineal resection (APER) in terms of short-term oncological and clinical outcomes. Methods This is a retrospective review of a prospectively maintained database including all the patients of rectal cancer who underwent APER at Tata Memorial Center between July 1, 2013, and January 31, 2015. Short-term oncological parameters evaluated included circumferential resection margin involvement (CRM), tumor site perforation, and number of nodes harvested. Peri operative outcomes included blood loss, length of hospital stay, postoperative perineal wound complications, and 30-day mortality. The χ2-test was used to compare the results between the two groups. Results Forty-two cases of ELAPER and 78 cases of conventional APER were included in the study. Levator involvement was significantly higher in the ELAPER compared with the conventional group; otherwise, the two groups were comparable in all the aspects. CRM involvement was seen in seven patients (8.9%) in the conventional group compared with three patients (7.14%) in the ELAPER group. Median hospital stay was significantly longer with ELAPER. The univariate analysis of the factors influencing CRM positivity did not show any significance. Conclusions ELAPER should be the preferred approach for low rectal tumors with involvement of levators. For those cases in which levators are not involved, as shown in preoperative magnetic resonance imaging (MRI), the current evidence is insufficient to recommend ELAPER over conventional APER. This stresses the importance of preoperative MRI in determining the best approach for an individual patient. PMID:27284466

The purpose of this study was to identify the most adequate strategy for group comparison of longitudinal patient-reported outcomes in the presence of possibly informative intermittent missing data. Models coming from classical test theory (CTT) and item response theory (IRT) were compared. Two groups of patients' responses to dichotomous items with three times of assessment were simulated. Different cases were considered: presence or absence of a group effect and/or a time effect, a total of 100 or 200 patients, 4 or 7 items and two different values for the correlation coefficient of the latent trait between two consecutive times (0.4 or 0.9). Cases including informative and non-informative intermittent missing data were compared at different rates (15, 30 %). These simulated data were analyzed with CTT using score and mixed model (SM) and with IRT using longitudinal Rasch mixed model (LRM). The type I error, the power and the bias of the group effect estimations were compared between the two methods. This study showed that LRM performs better than SM. When the rate of missing data rose to 30 %, estimations were biased with SM mainly for informative missing data. Otherwise, LRM and SM methods were comparable concerning biases. However, regardless of the rate of intermittent missing data, power of LRM was higher compared to power of SM. In conclusion, LRM should be favored when the rate of missing data is higher than 15 %. For other cases, SM and LRM provide similar results.

Clinical results, complications and the outcome of using either a carbon dioxide (CO₂) laser, diode laser or electrocautery (ELEC) for resection of the soft palate with an extended palatoplasty technique in brachycephalic dogs with upper airway obstructive syndrome were compared. Dogs were randomly allocated into three groups (n=20 in each group): ELEC, diode and CO₂ groups. The palatoplasty was made at the rostral aspect of the tonsils. A respiratory clinical score, ranging from 0 (normal) to 4 (cyanosis), was attributed to each dog before surgery and at 0 hours, 24 hours, two weeks and six months after surgery. A favourable outcome was defined as a one point or greater decrease in score 24 hours after surgery. The proportion of dogs with a favourable outcome was significantly higher in the CO₂ (n=15) and ELEC groups (n=15) in comparison with the diode group (n=7) (OR=5.6, 95 per cent confidence interval 1.4 to 21.9). Surgical time was significantly shorter (P<0.001; mean [sd] 510 [178] seconds), and bleeding was less common (P<0.001; 30 per cent of cases) in the CO₂ group. Complications were most frequent with the diode group (two cases of death and two cases of tracheostomy). The final outcome for all groups (n=57) was considered excellent in 79 per cent of cases and was considered good in 21 per cent.

It has been indicated that autologous hematopoietic stem cell transplantation (AHST) is a promising treatment to adults with type 1 diabetes, however, the application of AHST therapy to children with type 1 diabetes still needs more data. The aim of this study was to assess the clinical effect of immune intervention combined with AHST and conventional insulin therapy in the treatment of children with newly diagnosed type 1 diabetes. This 1:2 matched case-control study was comprised of 42 children who were newly diagnosed with type 1 diabetes in the Department of Endocrinology, Beijing Children's Hospital from 2009-2010. The case group included 14 patients, who were treated with AHST within the first 3 months after being diagnosed with diabetes at request of their parents during 2009-2010. The control group included 28 patients with newly diagnosed type 1 diabetes at the same period of hospitalization. We compared the baseline and follow-up data of them, including ketoacidosis onset, clinical variables (glycosylated hemoglobin (HbA1c), insulin dosage and serum C-peptide). The clinical characteristics of the patients was comparable between the case group and the control group. At 6-12 months ((10.7±4.2) months) after AHST treatment, we found 11 patients in the case group did not stop the insulin therapy, three cases stopped insulin treatment for 2, 3 and 11 months, respectively. No diabetic ketoacidosis (DKA) occurred after transplantation in all the patients in the case group. HbA1c in the control group was significant lower than that in the case group (P < 0.01), while the insulin dosage and serum C-peptide were not significant different between the two groups (P > 0.05). In order to eliminate the honeymoon effect, we performed final follow-up at the 3-5 years ((4.2±1.8) years) after AHST treatment, and found that HbA1c in the control group was still lower than that in the case group (P < 0.01); however, the insulin dosage and serum C-peptide were not significantly different between the two groups (P > 0.05). Moreover, the insulin dosage was not significant different from baseline to follow-up period in the case group. AHST treatment showed no advantage in effectiveness in children with newly diagnosed type 1 diabetes, both in insulin dose and long term blood glucose control.

(i) To report the successful treatment of 10 cases of equine periocular squamous cell carcinoma (PSCC) with surgical excision and photodynamic therapy (PDT) using verteporfin. (ii) To evaluate time to first tumor recurrence between PDT-treated horses and horses treated with surgical excision and cryotherapy. A total of 24 equine PSCC cases were included: group 1 (n = 14) had excision and cryotherapy (1993–2003), group 2 (n = 10), excision and local PDT (2006–2010). Evaluated data: signalment, treatment method, tumor location, size, and time to first recurrence. Groups were compared via chi-square test for categorical variables and Wilcoxon rank-sum test for numeric variables. Time to tumor recurrence was examined using Kaplan–Meier product-limit survival analysis. Of 24 cases, nine breeds were affected. Mean age at treatment in years: 14 (range 5–24) in group 1; 11 (range 8–18) in group 2. Median tumor size: 163 mm2 (range 20–625 mm2) in group 1; 195 mm2 (range 45–775 mm2) in group 2. Signalment, tumor laterality, and size were not significantly different between groups. Time to recurrence was significantly different between groups (Logrank test, P = 0.0006). In group 1, 11/14 horses had tumor regrowth with median time to recurrence in months: 10 (range 1–44). In group 2 (minimum follow-up of 25 months; range 25–50), no horse demonstrated tumor recurrence after one treatment with excision and PDT. This represents the first report of local PDT using verteporfin for treatment of equine PSCC. Following surgery, the likelihood of tumor recurrence was significantly reduced with local PDT compared with cryotherapy. © 2013 American College of Veterinary Ophthalmologists.

OVARIAN DYSFUNCTIOBJECTIVE: The study assesses the frequency of metabolic changes in overweight patients with or without polycystic ovary syndrome. The study group was made up by 148 patients of whom 99 patients without polycystic ovary syndrome (group A, control group) and 49 with polycystic ovary syndrome (group B), that came in our endocrine unit for a weight loss program, in the September 2008 March 2009 period. Morphometric parameters (height, weight, body mass index), biological parameters (cholesterol, triglycerides, blood glucose, glycated hemoglobin) and body composition analysis by measuring the electrical bioimpedance, were evaluated. Patients with polycystic ovary syndrome have a higher percentage of total fat (38.22+/-7.2) than patients without polycystic ovary syndrome (36.316+/-5.65) (p<0.05), for the same characteristics. Glycated hemoglobin, blood glucose and triglycerides were found higher in group B patients. Furthermore, the amount of free testosterone is higher in group B patients compared to those in group A. The prevalence of metabolic syndrome was higher in polycystic ovary syndrome cases (26.13%) comparative with overweight cases (16.16%, p<0.01). In the group of overweight patients, the group of patients with polycystic ovary syndrome is a particular group showing more severe metabolic changes.

The objective of our study was to assess, in a reader study, radiologists' performance in interpretation of automated breast volume scanner (ABVS) images with the aid of a computer-aided detection (CADe) system. Our study is a retrospective observer study with the purpose of investigating the effectiveness of using a CADe system as an aid for radiologists in interpretation of ABVS images. The multiple-reader, multiple-case study was designed to compare the diagnostic performance of radiologists with and without CADe. The study included 1000 cases selected from ABVS examinations in our institution in 2012. Among those cases were 206 malignant, 486 benign and 308 normal cases. The cancer cases were consecutive; the benign and normal cases were randomly selected. All malignant and benign cases were confirmed by biopsy or surgery, and normal cases were confirmed by 2-y follow-up. Reader performance was compared in terms of area under the receiver operating characteristic curve, sensitivity and specificity. Additionally, the reading time per case for each reader was recorded. Nine radiologists from our institution participated in the study. Three had more than 8 y of ultrasound experience and more than 4 y of ABVS experience (group A); 3 had more than 5 y of ultrasound experience (group B), and 3 had more than 1 y of ultrasound experience (group C). Both group B and group C had no ABVS experience. The CADe system used was the QVCAD System (QView Medical, Inc., Los Altos, CA, USA). It is designed to aid radiologists in searching for suspicious areas in ABVS images. CADe results are presented to the reader simultaneously with the ABVS images; that is, the radiologists read the ABVS images concurrently with the CADe results. The cases were randomly assigned for each reader into two equal-size groups, 1 and 2. Initially the readers read their group 1 cases with the aid of CADe and their group 2 cases without CADe. After a 1-mo washout period, they re-read their group 1 cases without CADe and their group 2 cases with CADe. The areas under the receiver operating characteristic curves of all readers were 0.784 for reading with CADe and 0.747 without CADe. Areas under the curves with and without CADe were 0.833 and 0.829 for group A, 0.757 and 0.696 for group B and 0.759 and 0.718 for group C. All differences in areas under the curve were statistically significant (p <0.05), except that for group A. The average reading time was 9.3% (p < < 0.05) faster with CADe for all readers. In summary, CADe improves radiologist performance with respect to both accuracy and reading time for the detection of breast cancer using the ABVS, with the greater benefit for those inexperienced with ABVS.

Objective: The research sought to determine whether case discussion at residents' morning report (MR), accompanied by a computerized literature search and librarian support, affects hospital charges, length of stay (LOS), and thirty-day readmission rate. Methods: This case-control study, conducted from August 2004 to March 2005, compared outcomes for 105 cases presented at MR within 24 hours of admission to 19,210 potential matches, including cases presented at MR and cases not presented at MR. With matching criteria of patient age (± 5 years), identical primary diagnosis, and secondary diagnoses (within 3 additional diagnoses) using International Classification of Diseases (ICD-9) codes, 55 cases were matched to 136 controls. Statistical analyses included Student's t tests, chi-squared tests, and nonparametric methods. Results: LOS differed significantly between matched MR cases and controls (3 days vs. 5 days, P < 0.024). Median total hospital charges were $7,045 for the MR group and $10,663 for the control group. There was no difference in 30-day readmission rate between the 2 groups. Discussion/Conclusion: Presentation of a case at MR, followed by the timely dissemination of the results of an online literature review, resulted in a shortened LOS and lower hospital charges compared with controls. MR, in association with a computerized literature search guided by the librarians, was an effective means for introducing evidence-based medicine into patient care practices. PMID:17971885

The aim of the study was to evaluate the incidence of congenital fetal anomalies reported among infertile Iranian women treated with letrozole compared to those treated with Clomiphene Citrate (CC). This retrospective case-control study was performed based on information available from infertile patients referred to the Akbar-Abadi Hospital IVF Center, Tehran, Iran, undergoing ovulation induction (OI) or intrauterine insemination (IUI) cycles from 2007 to 2014.We compared sonographic findings, fertility results, pregnancy complications and congenital anomalies in two groups of women treated with letrozole and CC. Overall, the results of the 2009 cycles including 1237 CC cycles and 772 letrozole cycles were evaluated. In spite of a higher chance of ovulation following CC treatment, overall fertility rates were similar in the two treatment groups. The frequency of adverse outcomes of pregnancy was similar in the two groups, except for the incidence of first trimester abortion, which was significantly higher in the CC-treated group. The frequency of fetal anomalies and major chromosomal abnormalities in the Letrozole group was 4.76% (five cases), and in the CC group, it was 2.12% (three cases). This difference was not statistically significant. Based on the findings of this study, it seems that the incidence of congenital anomalies in offspring after OI with letrozole is not increased compared to the CC group. © 2018 Japan Society of Obstetrics and Gynecology.

To investigate the clinical advantage of the application of modified Roux-en-Y reconstruction after totally laparoscopic total gastrectomy. Clinical data of 36 patients who underwent totally laparoscopic total gastrectomy with Roux-en-Y reconstruction by one medical team for gastric adenocarcinoma between January 2014 and December 2014 in the Second Hospital of Jilin University were retrospectively analyzed. Patients were divided into classic Roux-en-Y group (CRY, 16 cases) and modified Roux-en-Y group (MRY, 20 cases) according to reconstructive methods. The data concerning the intraoperative and postoperative situation in two groups were compared. Operation was successfully completed in all the cases without conversion to laparotomy. Compared to CRY group, MRY group had shorter mean operative time [(260.9 ± 21.2) min vs. (287.9 ± 19.0) min, P=0.000], shorter mean reconstruction duration [(32.4 ± 9.2] min vs. (45.4 ± 13.2) min, P=0.001] and less intraoperative bleeding [(50.9 ± 23.5) ml vs. (67.0 ± 20.5) ml, P=0.000]. Jejunum mesentery dissection and jejunum resection were not necessary in MRY group. However, there were no significant differences in lymph nodes harvested, time to flatus, hospital stay and postoperative complications between two groups. As compared to classic Roux-en-Y reconstruction, the modified Roux-en-Y reconstruction can simplify the surgical procedures and achieve similar efficacy. It is feasible and safe, and worth further promotion in clinical practice.

To find out if propranolol, a non-cardioselective beta-blocker, can reduce the anxiety associated with day case surgery. Prospective randomized double blind trial. University hospital, Ireland. An unselected group of 53 patients undergoing day case surgery. Subjects randomised to receive either propranolol (10 mg) or placebo on the morning of operation. Blood pressure; pulse, anxiety, pain score and patient satisfaction. Mean (SD) Hospital Anxiety and Depression score was significantly lower in the propranolol group than in the control group (2.5 (0.7) compared with 4.6 (0.7), p < 0.0001) before discharge. A low dose of propranolol given on the morning of day case surgery significantly reduced patients' anxiety.

Objective: To investigate the value of temporary balloon occlusion of the abdominal aorta in the treatment of complete placenta previa with placenta accreta. Methods: From January 2015 to February 2016, 24 cases of complete placenta previa with placenta accreta were treated with temporary balloon occlusion of the abdominal aorta(the study group)before cesarean, and 24 cases of complete placenta previa with placenta accreta did not receive balloon occlusion(the control group). The operation time, intraoperative blood loss, intraoperative blood transfusion volume, the perioperative hemoglobin level, the hysterectomy rate and the related complications were compared retrospectively.Also, the hospitalization time, the blood coagulation parameters after operation, including activated partial thromboplastin time(APTT), fibrinogen(FIB), D-Dimer and reperfusion injury parameters including creatine phosphokinase(CK), creatine phosphokinase isoenzyme(CK-MB), lactate dehydrogenase(LDH)and serum creatinine were compared between the 2 groups. Results: The blood loss[750 ml(400- 2 000 ml)vs 2 000 ml(1 500- 2 375 ml); Z =-3.214, P =0.001]and blood transfusion volume[200 ml(0-800 ml)vs 800 ml(0-1 200 ml); Z =- 2.173, P =0.030]in the study group were lower than in the control group. The hemoglobin difference between before and after operation in the study group was lower than the control group[(12.8±13.4)g/L vs(22.9±20.1)g/L; t =-2.041, P =0.047]. In the study group, there were still bleeding in 13 cases after releasing the balloon, 5 of them received uterine artery embolization, 5 cases received uterine artery ligation, and 3 cases received uterine packing. One case had venous thrombosis in the right lower limb. Two cases(8%,2/24)in the control group had hysterectomy, while none in the study group, there was no statistical significance( P = 0.489). Conclusions: Temporary balloon occlusion of the abdominal aorta can effectively reduce blood loss and blood transfusion in the treatment of complete placenta previa with placenta accreta, but there is still the risk of continuing bleeding after releasing the balloon. Other methods of hemostasis might be needed.

Objective: To evaluate the therapeutic effect of cervical Jiaji electroacupuncture on postoperative intractable hiccup of liver neoplasms. Methods: A total of 39 patients with postoperative intractable hiccup of liver neoplasms in The First Affiliated Hospital of Heilongjiang University of Chinese Medicine from May 2013 to May 2017 were collected and divided into 2 groups randomly. The electroacupuncture group included 20 cases, the control group included 19 cases. Patients in the electroacupuncture group were treated by cervical Jiaji electroacupuncture (located in C3-5, sympathetic ganglion), while the control group were treated by metoclopramide combined with chlorpromazine for three days. The therapeutic effects of two groups were compared and the onset time were recorded. Results: Total effective rates of electroacupuncture group and control group were 95.0% and 47.4%, respectively. The onset time in electroacupuncture group and control group were (14.8±3.3) h and (30.5±3.1) h, respectively ( P <0.01). Ten cases who resisted the control treatment were then treated by electroacupuncture for 3 days, 6 cases were recovered, 3 cases became better, while 1 case demonstrated no response. No serious adverse reactions were appeared in each group. Conclusion: Cervical Jiaji electroacupuncture is an effective and safe treatment for postoperative intractable hiccup of liver neoplasms, and it can be used as a remedy for intractable hiccup patients who don't respond to drug treatment.

To investigate the impact of three different training formats in occupational medicine (OM) on perceptions and performance of undergraduate students. A comparative study which included all fourth-year medical students was conducted over a three-year period. The year group in 2010 (211 students) received paper case studies followed by one small group session. The format used in 2011 actively engaged 188 students in the learning process by adding collaborative work and group discussions to the written information. In 2012, the approach comprised no longer constructed text cases but 212 students encountered real patients. Students' perceptions were obtained by questionnaire. Their learning performance was assessed through review of written reports and score on oral presentations. Statistical differences in ratings were analyzed using Fisher's exact and Kruskal-Wallis tests. All three formats were found to equally achieve the stated learning objectives. The year groups with incorporation of active learning strategies and patient contacts had significant better test performance compared to those receiving only written case studies. Real patient students gave statistically significant higher rates for relevance, authenticity and appropriate difficulty level of the training than did students who discussed written case studies. Both approaches with augmented interaction in 2011 and 2012, improved performance and satisfaction among students. However, students valued the use of real patients higher than paper-form cases.

Due to economic problems, sigmoid loop colostomy using glass rod may cause problems for our patients for finding glass rod and several visits. The aim of the study was to compare rod versus skin bridge colostomy. In this study, 42 cases who are candidate for colostomy were included. Cases were randomly placed in skin bridge and rod colostomy group. Independent sample t-test and Chi-square were used for comparison. SPSS version 16.0 (SPSS Inc, Chicago, IL, USA) was used for analysis. Of 42 cases, 20 were male and 22 were female. Hirschsprung's disease was the indication of colostomy in 33 cases. In nine cases, imperforate anus was the indication of colostomy. Mean time of surgery was 79.4 and 82.5 minute for the rod and skin bridge group respectively (P>0.05). Retraction was seen in 2 case of rod group, and no case of skin bridge group. Prolapse was seen in 2 (9.5%) case of rod group and 1(4.7%) case in skin bridge. There were no reports of necrosis, stenosis, and hernia in both groups. In the skin bridge group the rates of complications were lower but the groups are too small for statistical analysis. Colostomy with a skin bridge method may decrease number of revision and expenses and may be appropriate option. Sigmoid loop colostomy using skin bridge flap may be appropriate choice in developing country. Another study with more samples is recommended to better comparison of Skin Bridge versus rod colostomy.

Different forms of case management for dementia have emerged over the past few years. In the COMPAS study (Collaborative dementia care for patients and caregivers study), two prominent Dutch case management forms were studied: the linkage and the integrated care form. Evaluation of the (cost)effectiveness of two dementia case management forms compared to usual care as well as factors that facilitated or impeded their implementation. A mixed methods design with a) a prospective, observational controlled cohort study with 2 years follow-up among 521 dyads of people with dementia and their primary informal caregiver with and without case management; b) interviews with 22 stakeholders on facilitating and impeding factors of the implementation and continuity of the two case management models. Outcome measures were severity and frequency of behavioural problems (NPI) for the person with dementia and mental health complaints (GHQ-12) for the informal caregiver, total met and unmet care needs (CANE) and quality adjusted life years (QALYs). Outcomes showed a better quality of life of informal caregivers in the integrated model compared to the linkage model. Caregivers in the control group reported more care needs than those in both case management groups. The independence of the case management provider in the integrated model facilitated the implementation, while the rivalry between multiple providers in the linkage model impeded the implementation. The costs of care were lower in the linkage model (minus 22 %) and integrated care model (minus 33 %) compared to the control group. The integrated care form was (very) cost-effective in comparison with the linkage form or no case management. The integrated care form is easy to implement.

The aim of this study was to compare the obstetric outcomes after successful external cephalic version (cases) with a group of pregnant women with a spontaneous cephalic fetal position at delivery (controls). Retrospective review of the cohort of study was performed at the University Hospital of Getafe (Madrid, Spain) between January 2012 and January 2013. 1516 patients (48 cases; 1468 controls). We compared the type of delivery in pregnant women after ECV performed successfully (cases) with spontaneous cephalic presentations (controls). Pregnancies with vaginal delivery contraindicated, elective cesarean section (CS) justified by maternal disease, multiple pregnancies, or pregnancies below 37 weeks were excluded. Maternal age, BMI, parity, gestational age at delivery, and onset of labor (spontaneous or induced) were controlled. Prevalence of CS and operative delivery in both groups. Women who underwent a successful ECV had a significantly higher CS rate compared with the women of the control group (12/48 [25%] vs. 202/1468 [13.76%]; P=0.028). There was no difference in the rate of operative delivery (6/48 [12.5%] vs. 177/1468 [12.05%] P=0.92). Deliveries following a successful ECV are associated with an increased CS rate compared with deliveries of fetuses with spontaneous cephalic presentations.

Effects of human chorionic gonadotropin combined with clomiphene on serum E 2 , FSH, LH and PRL levels in patients with polycystic ovarian syndrome were analyzed. 90 patients with polycystic ovarian syndrome treated from January 2015 to March 2016 were randomly and evenly divided into control group and observation group. Patients in the control group were only treated with clomiphene. On the basis of the treatment in control group, human chorionic gonadotropin was added in the treatment of observation group. The changes of E 2 , FSH, LH, PRL levels were compared between two groups before and after the treatment. Clinical curative effects of patients in the two groups was evaluated. Adverse reactions during treatment in two groups were observed and recorded. The incidence of adverse reactions was calculated. Serum E 2 , FSH, LH and PRL levels in the two groups decreased significantly after treatment compared with that before treatment. The difference is statistical significant ( P  < 0.05). After the treatment, E 2 , FSH, LH and PRL levels in the observation group were lower than that in the control group and the difference is statistical significant ( P  < 0.05). Total effective rate was 64.44% in the control group and 93.33% in the observation group. There were statistically significant difference in clinical curative effects in the two groups ( P  < 0.05). Different degrees of adverse reactions were found in both groups during treatment, such as nausea, vomiting, anorexia, liver dysfunction. There were 2 cases of nausea, 2 cases of vomiting, 3 cases of anorexia and 1 case of liver dysfunction from the 45 patients in control group. The total incidence of adverse reactions was 17.78% (8/45). There were 1 case of nausea, 1 case of vomiting, 1 case of anorexia and no liver dysfunction from the 45 patients in observation group. The total incidence of adverse reactions was 6.67% (3/45). The total incidence of adverse reactions in the observation group was significantly higher than that in the control group and the difference was not statistically significant ( P  > 0.05). Combined use of human chorionic gonadotropin can significantly reduce serum E 2 , FSH, LH and PRL levels, improve clinical curative effects and reduce the incidence of adverse reactions. Human chorionic gonadotropin has high application value on the treatment of polycystic ovary syndrome.

To determine if (1) absorbed radiation dose and (2) fluoroscopy time decreased with experience over the first 100 cases of a single surgeon's hip arthroscopy practice. Subjects who underwent hip arthroscopy for symptomatic femoroacetabular impingement and labral injury were eligible for analysis. Inclusion criteria included the first 100 subjects who underwent hip arthroscopy by a single surgeon (December 2013 to December 2014). Subject demographics, procedure details, fluoroscopy absorbed dose (milligray [mGy]), and time were recorded. Subjects were categorized by date of surgery to one of 4 possible groups (25 per group). One-way analysis of variance was used to determine if a significant difference in dose (mGy) or time was present between groups. Simple linear regression analysis was performed to determine the relation between case number and both radiation dose and fluoroscopy time. Subjects underwent labral repair (n = 93), cam osteoplasty (n = 90), and pincer acetabuloplasty (n = 65). There was a significant (P < .001 for both) linear regression between case number and both radiation dose and fluoroscopy time. A significant difference in mGy was observed between groups, group 1 the highest and group 4 the lowest amounts of radiation (P = .003). Comparing individual groups, group 4 was found to have a significantly lower amount of radiation than group 1 (P = .002), though it was not significantly lower than that of group 2 (P = .09) or group 3 (P = .08). A significant difference in fluoroscopy time was observed between groups, group 1 the highest and group 4 the lowest times (P = .05). Comparing individual groups, group 4 was found to have a significantly lower fluoroscopy time than group 1 (P = .039). Correction for weight, height, and body mass index all revealed the same findings: significant (P < .05) differences in both dose and time across groups. The absorbed dose of radiation and fluoroscopy time decreased significantly over the first 100 cases of a single surgeon's hip arthroscopy practice learning curve.

In the daily practice of forensic pathology, sudden cardiac death (SCD) is a diagnostic challenge. Our aim was to determine the usefulness of blood biomarkers [creatine kinase CK-MB, myoglobin, troponins I and T (cTn-I and T), and lactate dehydrogenase] measured by immunoassay technique, in the postmortem diagnosis of SCD. Two groups were compared, 20 corpses with SCD and 8 controls. Statistical significance was determined by variance analysis procedures, with a post hoc Tukey multiple range test for comparison of means (p < 0.05). SCD cases showed significantly higher levels (p < 0.05) of cTn-T and cTn-I compared to the control group. Although only cases within the first 8 h of postmortem interval were included, and the control group consisted mainly of violent death cases, our results suggest that blood troponin levels may be useful to support a diagnosis of SCD. © 2017 American Academy of Forensic Sciences.

This study evaluates the effect of a care management service (CMS) on falls in older adults. This is a retrospective case-control study with 78 CMS recipients as the case group who received CMS and another 312 community-dwelling frail elders as the control group.The groups were matched by age, gender, activity of daily living, cognitive impairment, and unsteady gait. Thus they were comparable in characteristics and frailty. Among the 390 participants, 89 older adults (23.0%) had falls in the 90 days prior to the survey. After controlling for the identified risk factors for falls, the odds ratio of CMS was 0.27 (95% confidence interval = 0.110-0.663, p < .01). These findings indicate that CMS recipients have a lower chance for falls compared to their counterparts. The two features of CMS (comprehensive assessment and multidisciplinary actions to reduce fall risks) are discussed.

To compare the safety and effectiveness of circular stapler and linear stapler in Billroth II( anastomosis following distal gastrectomy for gastric cancer patients. Clinical data of gastric adenocarcinoma patients who received distal gastrectomy with Billroth II( anastomosis at Ward IIII( of Gastrointestinal Cancer Center of Peking University Cancer Hospital from January 2013 to April 2017 were collected retrospectively. (1) patients identified as stage IIII( gastric cancer by preoperative clinical and postoperative pathological staging. (2) patients undergoing emergency operation due to perforation, obstruction, or bleeding of digestive tract. (3) patients receiving chemotherapy before operation. (4) patients undergoing combined organ resection due to tumor involving other organs. (5) patients complicating with other malignancies. A total of 116 cases were enrolled and divided into circular stapler (CS, 61 cases) group and linear stapler (LS, 55 cases) group according to the application of mechanical stapler. Clinicopathological characteristics, operative conditions and postoperative recovery were compared between two groups. Differences in baseline data, such as tumor size, Lauren classification, differentiation grade, and pathologic stage, between two groups were not statistically significant (all P>0.05). The mean operative time (230 min vs. 234 min), median intra-operative blood loss (50.0 ml vs. 50.0 ml), median number of harvested lymph node (28.0 vs. 26.0) and median number of positive lymph node (1.0 vs. 2.0) between LS group and CS group were not significantly different (all P>0.05) As compared to CS group, LS group presented shorter median time to the first flatus (3.0 days vs. 4.0 days, P=0.038), shorter median time to the first liquid diet (7.0 days vs. 8.0 days, P=0.000), shorter median time to remove the first abdominal drainage tube (7.0 days vs. 9.0 days, P=0.000) and shorter median time of postoperative hospital stay (8.0 days vs. 10.0 days, P=0.000). The morbidity of postoperative complication was 11.5% and 1.8% in CS group and LS group respectively without significant difference (P=0.092). In CS group, 1 case (1.6%) developed anastomotic hemorrhage, 3 cases (4.9%) gastric emptying disorder and 3 cases (4.9%) abdominal infection after operation, who all were cured by conservative treatment without duodenal stump fistula and re-operation. In LS group, only 1 case (1.8%) developed duodenal stump fistula and was cured by re-operation. In distal gastrectomy with Billroth II( anastomosis for gastric cancer, the application of linear stapler results in faster recovery of gastrointestinal function and shorter hospital stay, indicating more advantages.

To compare the efficacy of carboxymethylcellulose 0.5% (CMC), hydroxypropyl-guar containing polyethylene glycol 400/propylene glycol (PEG/PG), and hydroxypropyl methylcellulose 0.3% (HPMC) as tear substitutes in patients with dry eye. A retrospective evaluation of cases presenting with symptoms of dry eye from July 2014 to June 2015 was done. Patients with Ocular Surface Disease Index (OSDI) scoring >12 were included in the study. Parameters such as age, gender, Schirmer test (ST), and tear film breakup time (TBUT) were recorded on day 0, week 1, and week 4. For analysis, cases were divided into three groups; Group 1 - CMC, Group 2 - PEG/PG, and Group 3 - HPMC. Overall, 120 patients were included in the study. Demographic data and baseline characteristics were comparable among the groups. Group 2 had significant improvement in percentage change in OSDI (weeks 0-1, 0-4, and 1-4, P = 0.00), TBUT (weeks 0-1, P = 0.01; 0-4, P = 0.006; and 1-4, P = 0.007), and in ST (weeks 0-1, P = 0.02; 0-4, P = 0.002; and 1-4, P = 0.008) compared to Group 1 at all follow-ups. Group 3 had improvements similar to Group 2, but it was not at all follow-ups (improvement in percentage change OSDI [weeks 0-1, 0-4, and 1-4, P = 0.00], TBUT [weeks 0-1, P = 0.10; 0-4, P = 0.03; and 1-4, P = 0.04], and in ST [weeks 0-1, P = 0.007; 0-4, P = 0.03; and 1-4, P = 0.12]). No significant difference was found between Groups 2 and 3. Hydroxypropyl-guar containing PEG/PG and HPMC as tear substitutes are better than CMC. While HPMC was comparable to PEG/PG in subjective improvement, the objective improvement was not consistent.

To evaluate the effectiveness of Ponseti method in the treatment of congenital talipes equinovarus (CTE) in children older than 6 months. Ponseti method was used to treat 157 cases (227 feet) of CTE in children older than 6 months. All cases were classified by age and by the degree of deformity severity. The age group classification was: (1) I Group (6 months to 12 months), 113 feet in 81 cases; (2) II Group (1 to 3 years old), 78 feet in 52 cases; (3) III Group (> 3 years old), 36 feet in 24 cases. The degree of deformity of CTE was evaluated with Pirani scoring system. The cases were classified into three groups according to the deformity degree: (1) Mild Group (scoring 1-2.5), 85 feet in 56 cases; (2) Moderate Group (scoring 3-4.5), 104 feet in 71 cases; (3) Severe Group (scoring 5-6), 38 feet in 30 cases. A Pirani score of 0-0.5 is regarded as an excellent result. For each group, we evaluated the number of casts used, the percentage of excellent result according to the Pirani score, and the percentage of percutaneous achillotenotomy. The result was compared among different groups. The overall percentage of excellent result among all cases was 96.92%. Among the age groups, the percentage of excellence was not statistically different between I Group and II Group (P > 0.05). The percentage of excellence was lower in the III group than the other groups (P > 0.01). Among the groups classified by deformity degree, the percentage of excellence was the lowest in severe group (P < 0.05), and the difference between the mild group and moderate group was not statistically different (P > 0.05). The number of casts used among different groups were different (P < 0.01). Among different groups, the percentages of percutaneous achillotenotomy were significantly different (P < 0.01). 209 feet in 148 cases were followed up for average time duration of 3 years and 11 months. Relapse was observed in 40 feet in 29 cases. The percentages of relapse were not statistically different among different groups (P > 0.05). Using Ponseti method to treat CTE for children older than 6 months can achieve excellent results in this study.

Hemoptysis is an important symptom which causes a major concern, and warrants immediate diagnostic attention. The authors compared a group of patients with pediatric pulmonary hemorrhage with pediatric patients diagnosed with extrapulmonary bleeding focusing on differences in etiology, outcome and differential diagnosis of hemoptysis. We performed the retrospective analysis of medical charts of 134 pediatric patients admitted to the Emergency Department because of pulmonary and extrapulmonary hemorrhage and were diagnosed with suspected hemoptysis or developed hemoptysis (ICD10-CM code R04.2). The cases with pulmonary hemorrhage (Group 1) were compared with cases of extrapulmonary bleeding (Group 2) using the Fisher Exact test or Pearson's χ 2 test for categorical variables. The t-test was used to assess differences between continuous variables of the patients in the two groups. Bloody cough was the presenting symptom in 73.9% of cases. 30 patients had pulmonary hemorrhage (Group 1), while 104 patients had extrapulmonary bleeding (Group 2). The underlying causes of bleeding in Group 2 included epistaxis, inflammatory diseases of nasopharynx and larynx, foreign bodies, gingivitis, and hypertrophy of adenoids. Mortality rate was 10% in Group 1, whereas Group 2 did not have any mortality outcomes during the observation period. Etiologycal factors were significantly different between hemoptysis and extrapulmonary bleeding in children. Our research suggested that pulmonary and extrapulmonary bleeding are two conditions that differ significantly and cannot be unified under one diagnostic code. It is important to differentiate between focal and diffuse cases, and between pulmonary and extrapulmonary hemorrhage due to the diversity of clinical courses and outcomes.

We conducted a case-control and screening method studies to estimate influenza vaccine effectiveness (IVE) in the age group >or=65 years, based on the Spanish Influenza Sentinel Surveillance System (SISSS). Cases (influenza laboratory-confirmed) were compared to influenza-negative ILI patients (test-negative) and patients without ILI since the beginning of the season (non-ILI). For the screening method, cases' vaccination coverage was compared to the vaccination coverage of the GPs' catchment population. The results suggested a protective effect of the vaccine against laboratory-confirmed influenza in elderly in 2008-2009. The screening method and the test-negative control designs enable estimating IVE using exclusively SISSS data. (c) 2010 Elsevier Ltd. All rights reserved.

AIM To compare argon laser photocoagulation and intrastromal injection of voriconazole as adjunctive treatment modalities in cases of resistant mycotic corneal ulcers. METHODS Two groups each of them included 20 cases of resistant mycotic corneal ulcers. Both groups treated with local and systemic specific antimicrobial drugs guided with culture and sensitivity results. In one group argon laser photocoagulation was used as an adjunctive therapy to the specific antifungal drugs and in the other group, intrastromal injection of voriconazole was done besides the specific antifungal drugs. The 40 cases included in the study were proven according to culture and sensitivity to be 28 cases with pure fungal results and 12 cases with mixed (fungal and bacterial). In argon laser group, argon laser irradiation of the corneal ulcer was performed using argon laser 532 nm wavelength (Carl Zeiss LSL 532s AG; Meditec, Inc.) after fluorescein staining. In the other group, voriconazole solution (500 µg/mL) was prepared and injected in the corneal stroma. All cases were followed up for 3mo after healing was achieved. RESULTS Complete healing of the epithelial defect and resolution of stromal infiltration with no adverse effects were achieved in argon laser group in duration ranged from 2-4wk in 90% of cases. In voriconazole group 4 cases needed amniotic membrane graft due to thinning and 16 cases healed in duration ranged from 2-6wk (80% of cases). CONCLUSION Argon laser photocoagulation is superior to intrastromal voriconazole injection in treatment of resistant fungal corneal ulcers. PMID:26949639

Background The benefits of endoscopic testing for colorectal-cancer screening are uncertain. We evaluated the effect of screening with flexible sigmoidoscopy on colorectal-cancer incidence and mortality. Methods From 1993 through 2001, we randomly assigned 154,900 men and women 55 to 74 years of age either to screening with flexible sigmoidoscopy, with a repeat screening at 3 or 5 years, or to usual care. Cases of colorectal cancer and deaths from the disease were ascertained. Results Of the 77,445 participants randomly assigned to screening (intervention group), 83.5% underwent baseline flexible sigmoidoscopy and 54.0% were screened at 3 or 5 years. The incidence of colorectal cancer after a median follow-up of 11.9 years was 11.9 cases per 10,000 person-years in the intervention group (1012 cases), as compared with 15.2 cases per 10,000 person-years in the usual-care group (1287 cases), which represents a 21% reduction (relative risk, 0.79; 95% confidence interval [CI], 0.72 to 0.85; P<0.001). Significant reductions were observed in the incidence of both distal colorectal cancer (479 cases in the intervention group vs. 669 cases in the usual-care group; relative risk, 0.71; 95% CI, 0.64 to 0.80; P<0.001) and proximal colorectal cancer (512 cases vs. 595 cases; relative risk, 0.86; 95% CI, 0.76 to 0.97; P = 0.01). There were 2.9 deaths from colorectal cancer per 10,000 person-years in the intervention group (252 deaths), as compared with 3.9 per 10,000 person-years in the usual-care group (341 deaths), which represents a 26% reduction (relative risk, 0.74; 95% CI, 0.63 to 0.87; P<0.001). Mortality from distal colorectal cancer was reduced by 50% (87 deaths in the intervention group vs. 175 in the usual-care group; relative risk, 0.50; 95% CI, 0.38 to 0.64; P<0.001); mortality from proximal colorectal cancer was unaffected (143 and 147 deaths, respectively; relative risk, 0.97; 95% CI, 0.77 to 1.22; P = 0.81). Conclusions Screening with flexible sigmoidoscopy was associated with a significant decrease in colorectal-cancer incidence (in both the distal and proximal colon) and mortality (distal colon only).

To evaluate the effects of acupoint massage for postpartum hypogalactia in puerpera. A total of 60 puerpera of cesarean section were randomized into an observation group and a control group, 30 cases in each one. In the observation group, 2 cases were dropped out. Finally, there were 28 cases in the observation group and 30 cases in the control group. In the control group, the routine nursing after operation in obstetrics department was given, guiding maternal breastfeeding and postpartum health education. In the observation group, on the basis of the treatment as the control group, the corresponding acupoints were selected from the breast related meridians for massage. Acupoint massage was given since the 3rd day after operation, 8:00 am to 9:00 am, once a day, 1 min at one acupoint, continuously for 5 days. The lactation volume, breast filling, galactostasis and milk viscosity were compared in the parturient of the two groups. The clinical therapeutic effects were compared between the two groups. From the 1st to the 2nd days, the differences were not significant in lactation volume, breast filling and galactostasis score between the two groups (all P >0.05). From the 3rd to 5th days, the lactation volume, breast filling and galactostasis score in the observation group were all lower than those in the control group (all P <0.01). The difference in milk viscosity was not significant in the first 4 days between the two groups (all P >0.05). On the 5th day, the score of milk viscosity in the observation group was lower than that in the control group ( P <0.01). The cured rate was 64.3% (18/28) in the observation group, which was better than 13.3% (4/30) in the control group ( P <0.05). Massage at the acupoints from the breast related meridians effectively promotes the lactation secretion in puerpera of postpartum hypogalactia and alleviates breast distention.

To investigate the central auditory processing function in children with functional articulation disorders (FAD), and possible causes of FAD. Twenty-seven children with FAD were selected as the case group and 50 age-matched normal children were selected as the control group. The two groups were compared with respect to the following factors: percentage of individuals with a positive history of language development disorder, and the form, peak latency and peak amplitude of mismatch negativity (MMN) on auditory event-related potentials. Compared with the control group, the case group had a significantly higher percentage of individuals with a positive history of language development disorder (70% vs 8%; P<0.01), a significantly prolonged peak latency of MMN (209 ± 31 ms vs 175 ± 32 ms; P<0.01), and an insignificantly lower peak amplitude of MMN (P>0.05). Prolonged central auditory processing may be one of the causes of FAD in children.

To compare the outcomes of tubeless day care PNL using hemostatic seal in the access tract versus standard PNL. It was a prospective randomized controlled study. Cases were randomized to either the day care group with hemostatic seal (DCS) or the control group where patients were admitted and a nephrostomy tube was placed at the conclusion of surgery. A total of 180 cases were screened and out of these, 113 were included in the final analysis. The stone clearance rates were comparable in both the groups. The mean drop in hemoglobin was significantly lower in DCS group than the control group (1.05 ±0.68 vs. 1.30 ±0.58 gm/dl, p = 0.038).Mean postoperative pain score, analgesic requirement (paracetamol) and duration of hospital stay were also significantly lower in the DCS group (3.79 ±1.23 vs. 6.12 ±0.96, 1.48 ±0.50 vs. 4.09 ±1.11 grams and 0.48 ±0.26 vs. 4.74 ±1.53 days respectively; p <0.05). The incidence of urine leakage through the access tract site was significantly lower in the DCS subgroup when compared to the controls (3.6% vs. 21.1%, p <0.05). Cases in the DCS group resumed their normal activities in a significantly shorter time (8.05 ±3.05 vs.18.42 ±4.42 days; p <0.05). Higher proportion of cases in the DCS group got re-admitted, although it was not a statistically significant number (7.1% vs. 1.8%; p = 0.21). Tubeless day care PNL with composite hemostatic tract seal is considered safe. It resulted in a significant reduction of blood loss and analgesic requirement with significantly reduced hospital stay, nephrostomy tube site morbidity and time required to resume normal activity when compared to the standard PNL. However, patients must be compliant with the given instructions and should have access to a health care facility, as few of them may need re-admission.

Purpose: To measure, quantify and compare Ocular Aberrations due to nuclear cataracts. Setting: Department of ophthalmology and school for ophthalmic technicians, college of medicine and health sciences, Sultan Qaboos University, Muscat, Oman. Design: Retrospective case controlled study. Methods: 113 eyes of 77 patients with nuclear cataract (NC) were recruited from outpatient clinic of a major tertiary referral center for Ophthalmology. Patients having NC with no co-existing ocular pathologies were selected. All patients were subjected to wavefront aberrometry (make) using Hartmann-Shack (HS) aberrometer. Consents were taken from all patients. Higher order Aberrations (HOA) were calculated with Zernike polynomials up to the fourth order. For comparison 28 eyes of 15 subjects with no lenticular opacities (control group) were recruited and evaluated in an identical manner. No pupillary mydriasis was done in both groups. Results: Total aberrations were almost six times higher in NC group compared to control (normal) subjects. The HOA were 21 times higher in NC group, and coma was significantly higher in NC eyes compared to normal (control) group. The pupillary diameter was significantly larger in control group (5.48mm ± 1.0024, p<.001) compared to NC (3.05mm ± 1.9145) subjects (probably due to younger control age group). Amongst Zernike coefficients up to fourth order, two polynomials, defocus (Z20) and spherical aberration (Z42) were found to be significantly greater amongst NC group, compared to normal control group. Conclusion: Nuclear cataracts predominantly produce increased defocus and spherical aberrations. This could explain visual symptoms like image deterioration in spite of normal Visual acuity.

2011-01-01

This comparative survey contrasted 571 parents who lost children to various death causes: 48 to drug-related deaths and overdoses, 462 to suicide, 24 to natural death cases, and 37 to mostly accidental death cases. Groups were compared in terms of grief difficulties, mental health problems, posttraumatic stress, and stigmatization. Results did not show any appreciable differences in these respects between the suicide bereaved parents and those losing children to drug-related deaths. However, when the suicide and drug-related death survivors were specifically contrasted against accidental and natural death loss cases, a consistent pattern emerged showing the former group was consistently more troubled by grief and mental health problems than the latter two sub-groups. These differences remained when controls of time since the loss and gender differences were employed as covariates. These findings suggest that the powerful and intense stigma against drug use and mental illness, shared among the public-at-large, imposes challenges in healing of immense proportion for these parents as they find less compassionate responses from their significant others, following their losses.

To examine trends of Rocky Mountain spotted fever (RMSF) incidence among American Indians compared with other race groups, a retrospective analysis of national RMSF surveillance data reported to the National Electronic Telecommunications System for Surveillance and the Tickborne Rickettsial Disease Case Report Forms system were used. The RMSF incidence for American Indians, which was comparable to those for other race groups during 1990-2000, increased at a disproportionate rate during 2001-2005. The average annual incidence of RMSF reported among American Indians for 2001-2005 was 16.8 per 1,000,000 persons compared with 4.2, 2.6, and 0.5 for white, black, and Asian/Pacific Islander persons, respectively. Most cases in American Indians were reported from Oklahoma (113.1 cases per 1,000,000), North Carolina (60.0), and Arizona (17.2). The incidence of RMSF increased dramatically among American Indians disproportionately to trends for other race groups. Education about tick-borne disease and prevention measures should be addressed for high-risk American Indian populations.

To summarize and compare the short-term and long-term clinical efficacy of percutaneous transhepatic biliary drainage (PTBD) and percutaneous transhepatic biliary stent (PTBS) in the treatment of malignant obstructive jaundice. 210 cases of malignant obstructive jaundice underwent interventional therapy, of which 161 cases of drainage catheters placement and 49 cases of metallic stent implantation. Follow-up information was obtained through telephone review or check-up records. The technical success rate of technique was 100%. At 3 - 5 days after treatment, the serum total bilirubin in 15 metallic stent-treated patients was decreased by (178.04 +/- 42.32) micromol/L, and direct bilirubin by (83.97 +/- 23.63) micromol/L. Compared with those of 28 cases treated with drainage catheters: (95.67 +/- 34.28) micromol/L and (49.84 +/- 28.21) micromol/L, there were statistically significant differences between the two groups (P = 0.017 and P = 0.035). At 6 - 9 days after treatment, the serum total bilirubin in 28 cases of metallic stent group was decreased by (188.22 +/- 79.90) micromol/L, and that in 126 cases of drainage catheter group decreased by (141.39 +/- 65.32) micromol/L. The difference was statistically significant (P = 0.014). But the decline value of direct bilirubin had no significant difference. The median patency period and the median survival time of the drainage catheter group were 60 and 148 days, respectively, those of metallic stent group were 197 days and 245 days. There were statistically significant differences between the two groups (P < 0.05). The results of this study indicate that the short-term and long-term efficacies of metallic stent implantation are better than those of catheter drainage technique.

To investigate the difference in the radiological features of malignant and benign branch duct type of IPMT (Intraductal Papillary Mucinous Tumor) of the pancreas. Thirty-six patients who were referred for operation with branch duct type of IPMT of the pancreas were included in this study. All cases underwent both CT and MRI with contrast enhancement. The size of the cystic lesions, the presence and size of mural nodules, and the amount of dilatation of the MPD were assessed by two independent radiologists, and the results were compared with pathological findings. Histological examination revealed adenoma in 8 cases, AH (atypical hyperplasia) in 8 cases, CIS (carcinoma in situ) in 8 cases and invasive carcinoma in 12 cases. Patients of the malignant group were older than those in the benign group (mean age: 67 yrs vs 60 yrs, respectively), but no statistically significant (p=0.05). Males (16/4 vs 10/6) more often complained weight loss and jaundice. The malignant tumor was more frequently located in the head-body and body. Compared with the benign group, the mean sizes of the cyst, mural nodules, MPD of the malignant group were 44 mm, 13 mm, 7.5 mm and benign group were 31 mm, 5 mm, 3.5 mm respectively. All these difference are statistically significant (p<0.05). In 4 cases of the 20 in the malignant group, soft tissue suggesting spread of disease into the adjacent viscera and peritoneum was detected. Cyst size over 30 mm and mural nodule over 8 mm, irregular thick septa, dilatation of the MPD, and accompany with soft tissue mass may be helpful factors in determining malignancy. Copyright © 2011.

Dental educators intend to promote integration of knowledge, skills, and values toward professional competence. Studies report that retrieval, in the form of testing, results in better learning with retention than traditional studying. The aim of this study was to evaluate test-enhanced experiences on demonstrations of competence in diagnosis and management of malocclusion and skeletal problems. The study participants were all third-year dental students (2011 N=88, 2012 N=74, 2013 N=91, 2014 N=85) at New York University College of Dentistry. The 2013 and 2014 groups received the test-enhanced method emphasizing formative assessments with written and dialogic delayed feedback, while the 2011 and 2012 groups received the traditional approach emphasizing lectures and classroom exercises. The students received six two-hour sessions, spaced one week apart. At the final session, a summative assessment consisting of the same four cases was administered. Students constructed a problem list, treatment objectives, and a treatment plan for each case, scored according to the same criteria. Grades were based on the number of cases without critical errors: A=0 critical errors on four cases, A-=0 critical errors on three cases, B+=0 critical errors on two cases, B=0 critical errors on one case, F=critical errors on four cases. Performance grades were categorized as high quality (B+, A-, A) and low quality (F, B). The results showed that the test-enhanced groups demonstrated statistically significant benefits at 95% confidence intervals compared to the traditional groups when comparing low- and high-quality grades. These performance trends support the continued use of the test-enhanced approach.

The aim of this study was to test the hypothesis that the superficial middle cerebral vein (SMCV) is frequently absent or fails to connect with the cavernous sinus (CS) in the presence of brain arteriovenous malformations (AVMs), a frequently reported argument for the congenital origin of brain AVMs. The SMCV was retrospectively compared between patients with a brain AVM and a control group. The presence or absence of the SMCV, its direct or indirect connection to the CS and its termination in a laterocavernous sinus (LCS), paracavernous sinus (PCS), or directly in the CS was studied on digital subtraction angiography. One hundred twenty-five left or right side carotid angiograms from 70 patients with a brain AVM were compared to 125 angiograms from 74 controls. The SMCV was present in 88 (70.4 %) cases in the brain AVM group and 96 (76.8 %) cases in controls (p = 0.25). The SMCV was connected directly or indirectly to the CS in 65 (52 %) cases in the brain AVM group and 65 (52 %) cases in controls (p = 1). When comparing the subgroup of carotid angiograms ipsilateral to a supratentorial AVM, no statistically significant difference was found with controls. In three of six cases in which a SMCV drained an AVM, the vein terminated directly or indirectly in the CS. No difference of SMCV presence and direct or indirect connection to the CS was found between patients with AVM and a control group. SMCV anatomy does not support the congenital origin of brain AVMs.

The management of obstructive left colon cancer (OLCC) remains debatable with the single-stage procedure of primary colonic anastomosis after cancer resection and on-table intracolonic lavage now being supported. Patients with acute OLCC who were admitted between January 2008 and January 2015 were distributed into 5 different groups. Group ICI underwent emergency laparotomy for primary anastomosis following colonic resection and intraoperative colonic lavage; Group HP underwent emergency Hartmann's Procedure; Group CON consisted of patients treated by conservative management with subsequent elective open cancer resection; Group COL were colostomy patients; and Group INT consisted of patients who had interventional radiology followed by open elective colon cancer resection. The demographics of the patients and comorbidity, intraoperative data, and postoperative data were collected, with P < .05 as significant. There were 4 deaths in 138 cases (2.90%). There was only 1 patient who had anastomotic leakage (5.56%) in Group ICI, compared with none in Group HP and Group COL, 1 case in Group INT (7.69%), and 2 cases in Group CON (6.06%) (P > .05). Group INT and Group CON, when compared to the three surgical groups, Groups ICI, Group COL, and Group HP, individually, were statistically significant for the duration of surgery (P < .05). Primary anastomosis following colonic resection after irrigation can be safely performed in selected patients, with the necessary surgical expertise, with no increased risk in mortality, anastomotic leakage, and other postoperative complications.

Elevated intra-abdominal pressure during the laparoscopy may promote bacteremia, endotoxemia, and systemic inflammatory response. In patients with generalized peritonitis from perforated peptic ulcer (PPU), we sought to compare acute phase response, immunologic status, and bacterial translocation from laparoscopic and open approach. From July 2005 to September 2011, 115 consecutive patients underwent peptic ulcer repair for PPU: 58 cases laparoscopic peptic ulcer repair (LR) and 57 cases open peptic ulcer repair (OR). Bacteremia, endotoxemia, white blood cells population, human leukocyte antigen-DR (HLA-DR), neutrophil-elastase, interleukin-1 and 6 (IL-1 and IL-6), and C-reactive protein (CRP) were investigated. Patients characteristics and grade of peritoneal contamination were similar in the two groups. One hour after intervention, bacteremia was significantly higher in the "open" group than in the laparoscopic group (p < .001). A significantly higher concentration of systemic endotoxin was detected intraoperatively in the "open" group of patients in comparison to the laparoscopic group (p < .0001). Laparotomy caused a significant increase in neutrophil concentration, neutrophil-elastase, IL-1 and IL-6, CRP, and decrease of HLA-DR. We recorded six cases (10.3%) of intra-abdominal abscess in the "open" group and one (1.7%) in laparoscopic group (p < .001). OR, in case of peritonitis after PPU, increased the incidence of bacteremia, endotoxemia, and systemic inflammation compared with LR. Early enhanced postoperative systemic inflammation may cause lower transient immunologic defense after laparotomy (decrease of HLA-DR), leading to enhanced sepsis in these patients.

To compare clinical outcomes of locking plate for proximal humeral fracture whether application of inferomedial screws. From January 2012 to July 2013, 46 patients with proximal humeral fracture underwent locking plates were retrospectively analyzed. There were 25 males and 21 females aged from 29 to 80 years old with an average of 55.1 years old. Among them, 25 patients were treated with inferomedial screws (support group), including 13 males and 12 females aged from 38 to 80 years old with an average of (55.8 ± 11.8) years old; 8 cases were part two fracture,10 cases were part three fracture and 7 cases were part four fracture according to Neer classification. Twenty-one patients were treated without inferomedial screws (non-support group), including 12 males and 9 females aged from 29 to 79 years old with an average of (54.2 ± 14.8)years old; 6 cases were part two fracture, 9 cases were part three fracture and 6 cases were part four fracture according to Neer classification. Operative time, fracture healing time and complications were observed and compared, Neer scoring of shoulder joint were used to evaluate clinical effect. All patients were followed up from 12 to 41 months with an average of 15.6 months. Operative time and fracture healing time in support group was (1.6 ± 0.4) h and (3.0 ± 0.6) months, and (1.5 ± 0.4) h and (3.1 ± 0.6) months in non-support group, while there was no statistical difference in operative time and fracture healing time between two groups. There was significant differences in Neer score between support group (89.7± 4.9) and non-support group (83.1 ± 7.1). No complication occurred in support group,while 4 cases occurred complications in non-support group. Locking plate with inferomedial screws for proximal humeral fracture has advantages of stable fixation, less complications, quick recovery of function and satisfied clinical effect.

We describe our experience with a modification of the piggyback (PB) technique for orthotopic liver transplantation in which the donor infrahepatic vena cava is used as the venous outflow tract. From May 1997 to January 2006, a total of 109 cases using this technique were performed in 101 patients. Collected data included recipient demographics and diagnosis, warm ischemia time, use of venovenous bypass or temporary portacaval shunt and complications related to the venous outflow and graft, and patient survival. Data were compared with the patients undergoing standard PB technique during the same period. The reasons for using the technique were grouped according to whether there was a problem with the recipient hepatic veins or a concern about the length or diameter of the donor suprahepatic vena cava. These included the presence of a transjugular intrahepatic portosystemic shunt (eight cases), retransplantation (22 cases), thin-walled, friable hepatic veins (32 cases), Budd-Chiari syndrome (two cases), domino liver procurement (six cases), reduced or split liver grafts (five cases), and graft inferior vena cava to recipient hepatic veins size discrepancy (34 cases). There was no graft loss. The warm ischemia time was 39.65 minutes compared with 37 minutes in the standard PB group. The long-term graft and patient survival rates were similar in the two groups. Infrahepatic vena cavocavostomy is a useful variation of the standard PB technique.

Educational technologies such as video cases can improve health professions student learning outcomes, but few studies in dentistry have evaluated video-based technologies. The goal of this study was to compare outcomes associated with video and paper cases used in an introductory public health dentistry course. This was a retrospective cohort study with a historical control group. Based on dual coding theory, the authors tested the hypotheses that dental students who received a video case (n=37) would report better affective, cognitive, and overall learning outcomes than students who received a paper case (n=75). One-way ANOVA was used to test the hypotheses across ten cognitive, two affective, and one general assessment measures (α=0.05). Students in the video group reported a significantly higher overall mean effectiveness score than students in the paper group (4.2 and 3.3, respectively; p<0.001). Video cases were also associated with significantly higher mean scores across the remaining twelve measures and were effective in helping students achieve cognitive (e.g., facilitating good discussions, identifying public health problems, realizing how health disparities might impact their future role as dentists) and affective (e.g., empathizing with vulnerable individuals, appreciating how health disparities impact real people) goals. Compared to paper cases, video cases significantly improved cognitive, affective, and overall learning outcomes for dental students.

The impact of chronic hepatitis B on the clinical outcome of acute hepatitis A remains controversial. The aim of present study was to evaluate the clinical characteristics of acute hepatitis A in cases with underlying chronic hepatitis B compared to cases of acute hepatitis A alone. Data on 758 patients with acute hepatitis A admitted at two university-affiliated hospitals were reviewed. Patients were classified into three groups: group A, patients with both acute hepatitis A and underlying chronic hepatitis B (n = 27); group B, patients infected by acute hepatitis A alone whose sexes and ages were matched with patients in group A (n  = 54); and group C, patients with acute hepatitis A alone (n = 731). None of the demographic features of group A were significantly different from those of group B or C, except for the proportion of males and body weight, which differed from group C. When comparing to group B, clinical symptoms were more frequent, and higher total bilirubin and lower albumin levels were observed in group A. When comparing to group C, the albumin levels were lower in group A. There were no differences in the duration of hospital stay, occurrence of acute kidney injury, acute liver failure, prolonged cholestasis, or relapsing hepatitis. This study revealed that clinical symptoms and laboratory findings were less favorable for patients with acute hepatitis A and chronic hepatitis B compared to those with acute hepatitis A alone. However, there were no differences in fatal outcomes or serious complications. Copyright © 2012 Wiley Periodicals, Inc.

Learning from Simple Ebooks, Online Cases or Classroom Teaching When Acquiring Complex Knowledge. A Randomized Controlled Trial in Respiratory Physiology and Pulmonology

2013-01-01

Background and Aims E-learning is developing fast because of the rapid increased use of smartphones, tablets and portable computers. We might not think of it as e-learning, but today many new e-books are in fact very complex electronic teaching platforms. It is generally accepted that e-learning is as effective as classroom teaching methods, but little is known about its value in relaying contents of different levels of complexity to students. We set out to investigate e-learning effects on simple recall and complex problem-solving compared to classroom teaching. Methods 63 nurses specializing in anesthesiology were evenly randomized into three groups. They were given internet-based knowledge tests before and after attending a teaching module about respiratory physiology and pulmonology. The three groups was either an e-learning group with eBook teaching material, an e-learning group with case-based teaching or a group with face-to-face case-based classroom teaching. After the module the students were required to answer a post-test. Time spent and the number of logged into the system was also measured. Results For simple recall, all methods were equally effective. For problem-solving, the eCase group achieved a comparable knowledge level to classroom teaching, while textbook learning was inferior to both (p<0.01). The textbook group also spent the least amount of time on acquiring knowledge (33 minutes, p<0.001), while the eCase group spent significantly more time on the subject (53 minutes, p<0.001) and logged into the system significantly more (2.8 vs 1.6, p<0.001). Conclusions E-learning based cases are an effective tool for teaching complex knowledge and problem-solving ability, but future studies using higher-level e-learning are encouraged.Simple recall skills, however, do not require any particular learning method.

Both serology-based and genetic studies have reported an association between pancreatic cancer risk and ABO blood groups. We have investigated this relationship in a cohort of pancreatic cancer patients from Western Norway (n = 237) and two control materials (healthy blood donors, n = 379; unselected hospitalized patients, n = 6149). When comparing patient and blood donor ABO allele frequencies, we found only the A 1 allele to be associated with significantly higher risk for pancreatic ductal adenocarcinoma (PDAC) (23.8% vs. 17.9%; OR = 1.43, P = 0.018). Analyzing phenotypes, blood group A was more frequent among PDAC cases than blood donors (50.8% vs. 40.6%; OR = 1.51, P = 0.021), an enrichment fully explained by the A 1 subgroup. Blood group O frequency was lower in cases than in blood donors (33.8% vs. 42.7%; OR = 0.69, P = 0.039). This lower frequency was confirmed when cases were compared to hospitalized patients (33.8% vs. 42.9%; OR = 0.68, P = 0.012). Results for blood group B varied according to which control cohort was used for comparison. When patients were classified according to surgical treatment, the enrichment of blood group A was most prominent among unresected cases (54.0%), who also had the lowest prevalence of O (28.7%). There was a statistically significant better survival (P = 0.04) for blood group O cases than non-O cases among unresected but not among resected patients. Secretor status did not show an association with PDAC or survival. Our study demonstrates that pancreatic cancer risk is influenced by ABO status, in particular blood groups O and A 1 , and that this association may reflect also in tumor resectability and survival. © 2017 The Authors.

To compare skills acquired by undergraduate nursing students enrolled in a medical-surgical course. To compare skills demonstrated by students with no previous clinical practice (undergraduates) and nurses with clinical experience enrolled in continuing professional education (CPE). In a nonrandomized clinical trial, 101 undergraduates enrolled in the "Adult Patients 1" course were assigned to the traditional lecture and discussion (n = 66) or lecture and discussion plus case-based learning (n = 35) arm of the study; 59 CPE nurses constituted a comparison group to assess the effects of previous clinical experience on learning outcomes. Scores on an objective structured clinical examination (OSCE), using a human patient simulator and cases validated by the National League for Nursing, were compared for the undergraduate control and intervention groups, and for CPE nurses (Student's t test). Controls scored lower than the intervention group on patient assessment (6.3 ± 2.3 vs 7.5 ± 1.4, p = .04, mean difference, -1.2 [95% confidence interval (CI) -2.4 to -0.03]) but the intervention group did not differ from CPE nurses (7.5 ± 1.4 vs 8.8 ± 1.5, p = .06, mean difference, -1.3 [95% CI -2.6 to 0.04]). The CPE nurses committed more "rules-based errors" than did undergraduates, specifically patient identifications (77.2% vs 55%, p = .7) and checking allergies before administering medication (68.2% vs 60%, p = .1). The intervention group developed better patient assessment skills than the control group. Case-based learning helps to standardize the process, which can contribute to quality and consistency in practice: It is essential to correctly identify a problem in order to treat it. Clinical experience of CPE nurses was not associated with better adherence to safety protocols. Case-based learning improves the patient assessment skills of undergraduate nursing students, thereby preparing them for clinical practice. © 2014 Sigma Theta Tau International.

Existing single-case studies have reported deficit in recognizing basic emotions through facial expression and unaffected performance with body expressions, but not the opposite pattern. The aim of this paper is to present a case study with impaired emotion recognition through body expressions and intact performance with facial expressions. In this single-case study we assessed a 30-year-old patient with autism spectrum disorder, without intellectual disability, and a healthy control group (n = 30) with four tasks of basic and complex emotion recognition through face and body movements, and two non-emotional control tasks. To analyze the dissociation between facial and body expressions, we used Crawford and Garthwaite's operational criteria, and we compared the patient and the control group performance with a modified one-tailed t-test designed specifically for single-case studies. There were no statistically significant differences between the patient's and the control group's performances on the non-emotional body movement task or the facial perception task. For both kinds of emotions (basic and complex) when the patient's performance was compared to the control group's, statistically significant differences were only observed for the recognition of body expressions. There were no significant differences between the patient's and the control group's correct answers for emotional facial stimuli. Our results showed a profile of impaired emotion recognition through body expressions and intact performance with facial expressions. This is the first case study that describes the existence of this kind of dissociation pattern between facial and body expressions of basic and complex emotions.

Smoking is an important risk factor of TB. However, no studies have been conducted to identify TB cases from smokers. We assessed the process and initial impact of active case finding among smokers at primary care facilities in a setting with high smoking rates and TB burden. A prospective quasi-experimental study was conducted in para-urban communities in Yunnan China between September 2013 and June 2014. Smokers attending primary care facilities in the intervention group were prescribed chest X-rays if they had diabetes or TB symptoms, or were elders or close contacts of TB patients. Those with X-rays suggestive of TB were referred to TB dispensaries for diagnosis. Passive case finding was practiced in the control group. In the intervention group, we screened 471 smokers with high risks of TB, of whom 73% took chest X-ray examinations. Eight TB cases were diagnosed, reflecting a 1.7% yield rate of all screened smokers. Smokers with diabetes (OR 6.003, 95% CI 1.057-34.075) were more likely to have TB compared with those without. In total, the intervention group reported significantly higher TB notification rate compared with the control group (38.6 vs 22.9 per 100 000, p=0.016). Active case finding among smokers with high risks of TB was feasible and contributed to improved notification rates. © The Author 2015.

We set out to determine which patients admitted for expectant management of early onset severe pre-eclampsia develop abruptio placentae and to compare the perinatal mortality rate of patients who developed abruptio placentae with those who did not have this complication. This was a case controlled study, using gestational age at delivery to select a control group for 69 patients who developed abruptio placentae. The only significant difference on admission was the higher uric acid levels in patients who developed abruptio placentae. Mean admission to delivery intervals were 11.9 and 8.8 days for the control and abruption groups respectively (P = 0.0083). Fifty-eight per cent of the babies in the abruptio placentae group developed late decelerations, as determined by fetal heart rate monitoring compared with 32% in the control group. Lactate dehydrogenase levels before delivery were significantly higher in the abruption group, but it only became elevated shortly before delivery and in the minority of cases. There were two intrauterine and four neonatal deaths in the abruption group and two neonatal deaths in the control group. Late decelerations detected by frequent fetal heart rate monitoring in patients with early onset severe pre-eclampsia is the only early warning of abruptio placentae.

To explore the difference of the proximal femoral shortening (PFS) between the third generation of Gamma nail (TGN) and the proximal femoral nail anti-rotation (PFNA) in treating intertrochanteric fracture of femur. The clinical data of 158 patients with intertrochanteric fracture of femur who were treated with TGN internal fixation or PFNA internal fixation between January 2014 and December 2015 were retrospectively analysed. The patients were divided into TGN group (69 cases) and PFNA group (89 cases) according to surgical operation. There was no significant difference in gender, age, bone mineral density, causes of injury, AO/Association for the Study of Internal Fixation (AO/ASIF) classification, accompanied disease, and the time from injury to operation between 2 groups ( P >0.05). The result of fracture reduction was divided into 3 types: positive medial cortex support, neutral position cortex support, and negative medial cortex support according to the method of Chang et al . At 18 months postoperatively, bilateral hip anteroposterior X-ray films were taken to measure horizontal PFS values (marked as X), vertical PFS values (marked as Y), and calculate the total PFS values (marked as Z). The PFS values were divided into 4 grades according to the criteria (≤1.0 mm, 1.0-4.9 mm, 5.0-9.9 mm, and ≥10.0 mm), and the constituent ratio was calculated and compared between 2 groups. The X, Y, and Z values and the collodiaphyseal angles of 2 groups at 18 months postoperatively were compared. The X, Y, and Z values of 2 groups of patients with failed fixation and normal healing within 18 months after operation were recorded and compared. The X, Y, and Z values of 2 groups of the patients with different cortex support types were also compared. There were 34 cases of positive medial cortex support, 30 cases of neutral position cortex support, and 5 cases of negative medial cortex support in TGN group, and there were 45, 33, and 11 cases in PFNA group respectively, showing no significant difference between 2 groups ( Z =-1.06, P =0.29). All patients were followed up 18 months after operation. At 18 months after operation, the constituent ratios of PFS values (X, Y, Z) had significant differences between 2 groups ( P <0.05). The patients of shortening of 1.0-4.9 mm and 5.0-9.9 mm were obviously more in TGN group than in PFNA group; the patients of shortening of ≥10.0 mm were obviously more in PFNA group than in TGN group. There were significant differences in X, Y, and Z values between 2 groups ( P <0.05), but no significant difference of the collodiaphysial angle was found between 2 groups ( t =0.47, P =0.64). Six cases of internal fixation failed in TGN group and PFNA group respectively within 3 months after operation, and there was no significant difference of X, Y, and Z values between failed fixation and normal healing patients within 2 groups ( P >0.05). When the reposition effect was the positive medial cortex support, the X, Y, and Z values were significantly lower in TGN group than in PFNA group ( P <0.05); but no significant difference was found between 2 groups when the reposition effect was the neutral position cortex support or negative medial cortex support ( P >0.05). At 18 months after operation, the X, Y, and Z values of the negative medial cortex support patients were significantly higher than those of the positive medial cortex support or the neutral position cortex support patients within 2 groups ( P <0.05). PFS is a common complication of the intertrochanteric fracture of the femur after internal fixation. During operation, the selection of internal fixation should be based on the results of intraoperative reduction. TGN should be applied to reduce PFS if positive medial cortex support happened.

In the era of effective modern systemic chemotherapy (CT), the role of hepatic arterial infusion of fluoxuridine (HAI-FUDR) in the treatment of isolated unresectable colorectal liver metastasis (IU-CRCLM) remains controversial. This study aimed to compare the overall survival (OS) of HAI-FUDR in combination with modern systemic CT versus modern systemic CT alone in patients with IU-CRCLM. This was a case-control study of IU-CRCLM patients who underwent HAI + modern systemic CT or modern systemic CT alone. Modern systemic CT was defined as the use of multidrug regimens containing oxaliplatin and/or irinotecan ± biologics. Overall, 86 patients met the inclusion criteria (n = 40 for the HAI + CT group, and n = 46 for the CT-alone group). Both groups were similar in demographics, primary and stage IV tumor characteristics, and treatment-related variables (carcinoembryonic antigen, use of biologic agents, total number of lines of systemic CT administered) (all p > 0.05). Additionally, both groups were comparable with respect to liver tumor burden [median number of lesions (13.5 vs. 15), percentage of liver tumor replacement (37.5 vs. 40 %), and size of largest lesion] (all p > 0.05). Median OS in the HAI + CT group was 32.8 months compared with 15.3 months in the CT-alone group (p < 0.0001). Multivariate analysis revealed HAI + CT (hazard ratio 0.4, 95 % confidence interval 0.21-0.72; p = 0.003), Eastern Cooperative Oncology Group status, and receipt of increasing number of lines of systemic CT to be independent predictors of survival. In this case-control study of patients with IU-CRCLM, HAI in combination with CT was associated with improved OS when compared with modern systemic CT alone.

Plasma samples were collected from 110 stillborn calves with bacterial infection (INF_B, n = 16), with viral or parasitic infection (INF_V/P, n = 31) during pregnancy, with lesions of fatal traumotocia (TRAUM, n = 22), and from unexplained deaths (UNEXPL, n = 41). Plasma immunoglobulin and SAA concentrations were measured by ELISA, and Hp concentrations were measured by the guaiacol method and ELISA. Concentrations of SAA in the INF_B group were higher than in the UNEXPL group and tended to be higher than in the INF_V/P group. A reference range (0-29 mg/L) was established for SAA in stillborn calves. Concentrations of Hp tended to be higher in the INF_B group compared with INF_V/P group. Concentrations of IgM tended to be higher in the INF_B group compared with the TRAUM and INF_V/P groups. Concentrations of IgG 1 were numerically, but not significantly, higher in the INF_V/P and INF_B groups compared with the other groups. The results demonstrate upregulation of immune and inflammatory responses in stillborn calves exposed to bacterial infection in utero. The immune-inflammatory parameters did not differ between calves with viral or parasitic infections and traumotocia. These immune-inflammatory profiles did not contribute to the diagnosis of unexplained stillbirth. This is the first report of an elevated acute phase protein response in stillborn calves. Measurement of SAA and IgM concentrations may be used in the diagnosis of bacterial infections in stillborn calves. Copyright © 2017 American Dairy Science Association. Published by Elsevier Inc.

Team-based learning is a large-group instructional modality intended to provide active learning with modest faculty resources. The goal is to determine if team-based learning could be substituted for small-group learning in case sessions without compromising test performance or satisfaction. One hundred and sixty-seven students were assigned to team-based or small-group learning for 6 case discussion sessions. Examination scores and student satisfaction were compared. Instruction modality had no meaningful effect on examination score, 81.7% team based versus 79.7% small-group, p=.56 after multivariate adjustment. Student satisfaction was lower with team-based learning, 2.45 versus 3.74 on a 5-point scale, p<.001. Survey responses suggested that the very small size (8-10 students) of our small groups influenced the preference for small-group learning. Team-based learning does not adversely affect examination performance. However, student satisfaction may be inferior, especially if compared to instruction in very small groups of 10 or fewer students.

To investigate the education effect of case-based learning (CBL) pattern on clinical internship of conservative dentistry and endodontics. Forty-one undergraduates were randomly assigned into CBL group and traditional teaching group. After clinical internship in the department of conservative dentistry and endodontics for 11 weeks, each student in the 2 groups underwent comprehensive examinations including medical record writing, case analysis, academic knowledge, professional skills and the ability of winning the trust of the patients. The scores were compared between the 2 groups using SPSS 13.0 software package. There was no significant difference between the 2 groups with regard to the scores of academic knowledge and profession skills (P>0.05). However, the results of medical record writing, case analysis and the ability of winning the trust of the patients showed significant difference between the 2 groups(P<0.05). Proper application of CBL in clinical internship of conservative dentistry and endodontics contributes to improve students' ability of clinical thinking, synthetical analysis and adaptability to different patients.

Objectives Perinatal asphyxia (PA) is very significant in perinatal medicine due to the involvement of the central nervous system. This study was conducted to investigate the biochemical, clinical, and paraclinical changes associated with phenobarbital administration in neonates with PA. Methods In this prospective, case-control study, 30 neonates with PA in two groups of 15 each (case and control) were investigated. The case group received 20 mg/kg intravenous phenobarbital within six hours of birth, and the control group did not receive phenobarbital. Serum concentrations of nitric oxide (NO) were measured at enrollment and one week after birth in the two groups. Clinical, electroencephalography, and magnetic resonance imaging findings of the two groups were compared. Results At enrollment, the two groups did not differ in clinical severity, seizure incidence, or NO concentration. After one week, NO concentration was significantly lower in the case group (p < 0.050), but there was no significant difference in other variables between the two groups. Conclusions Early administration of phenobarbital in term neonates with PA could protect them against encephalopathy. PMID:27602186

To observe the clinical efficacy on migraine treated with acupoint implantation. Sixty cases of migraine were randomized into a implantation group and an electroacupuncture (EA) group, 30 cases in each one. In the implantation group, implantation was used at Fengchi (GB 20), Taiyang (EX-HN 5), Waiguan (TE 5), Yanglingquan (GB 34), etc., once every 2 weeks, for 4 weeks totally. In the EA group, the acupoints were the same as the implantation group, and EA was applied to Fengchi (GB 20) and Taiyang (EX-HN 5), Yanglingquan (GB 34) and Zusanli (ST 36), once every two days, for 4 weeks totally. The visual analogue scale (VAS) was adopted before and after treatment and the clinical efficacy was compared between the two groups. After treatment, VAS score was reduced in the implantation group and the EA group as compared with that before treatment (both P < 0.01). After treatment, VAS score in the implantation group was lower than that in the EA group (P < 0.01). The difference in VAS score before and after treatment in the implantation group was improved apparently as compared with that in the EA group (P < 0.01). The total effective rate in the implantation group was higher than that in the EA group (P < 0.05). The acupoint implantation reduces VAS score in the patients of migraine and its clinical efficacy is better than that in the EA group. The therapy presents the long-term clinical effect and deserves to be promoted in clinical practice.

To compare the outcomes between autologous blood- and fibrin glue-fixated conjunctival autografts in pterygium excision surgery. Retrospective case series. Forty eyes of 40 patients who had a primary nasal pterygium excision. A retrospective comparative case series of 40 eyes (40 patients) that had a primary nasal pterygium excision. All eyes had a conjunctival autograft from the superior bulbar conjunctiva to cover the scleral bed. Twenty eyes (20 patients) had fixation of the autograft using autologous blood (AB), and 20 eyes (20 patients) had fixation using fibrin glue (FG). One year of follow-up data included conjunctival graft stability (graft loss, graft retraction), pterygium recurrence, visual acuity, and postoperative complications. Descriptive and inferential statistics were performed. Intraoperatively, no complications occurred in either group. Graft loss occurred in 6 patients in the AB group, compared with none in the FG group. Graft retraction occurred in 3 patients in the AB group and 2 patients in the FG group. At 1 year postoperatively, pterygium recurrence occurred in 4 patients in the AB group and 1 patient in the FG group. One patient in the AB group developed a small pyogenic granuloma that resolved by 6 months with conservative management. Visual acuity remained stable in both groups. Conjunctival autograft fixation with autologous blood resulted in less stable conjunctival autografts and a higher recurrence rate compared with fixation with fibrin glue.

The study was carried out to evaluate which drug is better in ovulation induction between clomiphene citrate and letrozole. The study was carried out in the infertility unit of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka and Centre for Assisted Reproduction (CARE) at Bangladesh Institute of Research and Rehabilitation in Diabetes Endocrine and Metabolic Disorders (BIRDEM), Dhaka from January 2007 to December 2007. One hundred and sixty five cases were taken for the study. It was a prospective interventional comparative study of clomiphene citrate and letrozole in infertile cases. The patients were divided into three groups. Group I--newly detected cases of sub fertility studied with clomiphene citrate. Group II--clomiphene citrate resistant cases studied with letrozole, Group III--newly detected cases of sub fertility studied with letrozole. The cases were followed up for outcome; (ovulation). The TVS was done on 12th or 13th day of menstruation and level of serum progesterone on 21st day of menstrual cycle to see the evidence of ovulation. Endometrial thickness was also measured. The data was collected on a predesigned questionnaire. The variables that influenced the study were-age, occupation, socioeconomic status, menstrual cycle, marital age, parity, history of MR, history of abortion, past medical and surgical history. In the current study it was observed that the signs of ovulation were significantly (p<0.05) higher in Group I treated with clomiphene citrate in comparison to Group II clomiphene citrate resistant cases treated with letrozole. The rate of ovulation was higher in Group I than that of Group III treated with letrozole, but the difference was not statistically significant (p>0.05). The signs of ovulation were present in 45(81.8%) cases in Group I, 33(60.0%) cases in Group II and 37(67.3%) cases in Group III. This findings of the study suggested that clomiphene citrate is higher successful than letrozole though not statistically significant. Letrozole can be preferred in clomiphene citrate resistant cases before starting other expensive therapies.

To compare healthcare utilization and costs between subjects with and without fibromyalgia (FM) using claims data from a large health benefits company in the United States. Retrospective cohort. We analyzed 24 months of medical and pharmacy claims data comparing healthcare utilization and costs among Humana members diagnosed with FM to a propensity score matched control group without a diagnosis for FM. FM cases were identified as members aged 18 years and older, with at least 2 medical claims for International Classification of Diseases, Ninth Revision, Clinical Modification codes 729.0 and/or 729.1. The first medical claim for FM was utilized as the index date. A total of 9988 FM cases and 9988 controls were included in the analysis. Compared with controls, the use of pain-related medications by FM cases was approximately 2 times higher with opioids being used most commonly. FM cases utilized a mean (SD) of 22.5 (23.9) and 31.1 (26.6) outpatient services per year in the prediagnosis and postdiagnosis periods, respectively, compared with 14.8 (20.5) and 16.3 (24.5) among controls (P <.01). Office visits, tests, and procedures represented the majority of utilization. During the postdiagnosis period, the mean per-patient per-month costs for outpatient services among FM cases was $377 ($760) and $217 ($740.87) among controls (P <.01). FM cases had significantly higher utilization and costs compared with controls. Office visits, tests and procedures, and the use of pain-related medications accounted for the largest absolute differences between the 2 groups.

To assess (1) the effect of case-based instructional modules on student critical thinking, class attendance, and satisfaction and (2) student opinion of case formats. University-based upper division course in clinical immunology and serology. The course was taught by the same instructor for two consecutive semesters with the intervention introduced in the second semester. Sixty-seven students experienced the intervention and 56 students were in the baseline cohort. Nine cases were interspersed between lectures during the semester. Each case took one 50-minute class in which students worked in groups of five or six. Student performance on five critical thinking multiple-choice examination questions and percent student attendance on case days versus lecture days were analyzed using the Mann-Whitney test. Student ratings on course evaluations were analyzed using t-test comparing semesters with and without intervention. Student opinion of cases was obtained through surveys and a focus group. Student performance on critical thinking exam questions was similar in the two groups. Student attendance was significantly higher on case days (95.6%) versus lecture days (80.3%; p < 0.0001). Only composite ratings for instructor involvement, student-instructor interaction, and course organization were significantly improved in the semester with cases compared to the semester with lecture only (p < 0.0001 for all indices). Although case studies did not significantly improve student performance on critical thinking questions, they still proved to be a valuable instructional method. Student attendance, student-instructor interaction, and instructor involvement in the course were all positively affected by incorporation of case studies. Discussion of cases also helped to uncover student misconceptions of course material.

Simulation is increasingly used in medical education, promoting active learning and retention; however, increasing use also requires considerable instructor resources. Simulation may provide a safe environment for students to teach each other, which many will need to do when they enter residency. Along with reinforcing learning and increasing retention, peer teaching could decrease instructor demands. Our objective was to determine the effectiveness of peer-taught simulation compared to physician-led simulation. We hypothesized that peer-taught simulation would lead to equivalent knowledge acquisition when compared to physician-taught sessions and would be viewed positively by participants. This was a quasi-experimental study in an emergency medicine clerkship. The control group was faculty taught. In the peer-taught intervention group, students were assigned to teach one of the three simulation-based medical emergency cases. Each student was instructed to master their topic and teach it to their peers using the provided objectives and resource materials. The students were assigned to groups of three, with all three cases represented; students took turns leading their case. Three groups ran simultaneously. During the intervention sessions, one physician was present to monitor the accuracy of learning and to answer questions, while three physicians were required for the control groups. Outcomes compared pre-test and post-test knowledge and student reaction between control and intervention groups. Both methods led to equally improved knowledge; mean score for the post-test was 75% for both groups (p=0.6) and were viewed positively. Students in the intervention group agreed that peer-directed learning was an effective way to learn. However, students in the control group scored their simulation experience more favorably. In general, students' response to peer teaching was positive, students learned equally well, and found peer-taught sessions to be interactive and beneficial.

Surgical options for medial temporal lobe epilepsy (MTLE) include anterior temporal lobectomy (ATL) and selective amygdalohippocampectomy (SAH). Optimal criteria for choosing the appropriate surgical approach remain uncertain. This article reports 11 consecutive cases in which electrophysiological findings of stereoelectroencephalography (SEEG) were used to determine the optimal surgical approach. Eleven consecutive patients with MTLE underwent SEEG evaluation and were placed in either the medial or the medial+lateral group based on the findings. Patients in the medial group underwent SAH using the subtemporal approach, and patients in the medial+lateral group underwent SEEG-guided anterior temporal lobectomy. SEEG findings were also compared with other examinations including flumazenil (FMZ)-positron emission tomography (PET), fluorine-18 labeled fluorodeoxyglucose (FDG)-PET, and magnetoencephalography (MEG). Results were evaluated to determine which examinations most consistently identified the epileptogenic zone. Of the 11 cases, 4 patients were placed in the medial group, and 7 patients in the medial+lateral group. Of patients, 90.9% were classified in class I of the Engel Epilepsy Surgery Outcome Scale, while 72.7% were classified in class I by the International League Against Epilepsy (ILAE) system. Analyzed by group, 100% of the medial group experienced an Engel class I outcome in the medial group, compared to 85.7% in the medial+lateral group. SEEG findings were comparable with FDG-PET results (10 of 11, 91%). Tailored surgery guided by SEEG is an electrophysiologically feasible treatment for MTLE that can result in favorable outcomes. Although seizures are thought to originate in the medial temporal lobe in MTLE, it is important for involvement of the lateral temporal cortex to be also considered in some cases. Copyright © 2017.

The application of quantitative EEG (δ+θ/α+β value) and GCS value to evaluate the role of music therapy for traumatic brain injury coma patients. Forty patients of traumatic brain injury coma were selected to meet the inclusion criteria. Twenty cases were selected for the rehabilitation, neurology and neurosurgery ward, whose families could actively cooperate with, and the patients could receive a long-term fixed nursing staff with formal music therapy (music group). Twenty cases were in the intensive care unit of the rehabilitation, neurology and neurosurgery ward. Their families members cooperated poorly, had often changing nursing staff, and without a formal music therapy (control group). After a one monthe follow up, the GCS value and quantitative EEG (δ+θ/α+β value) were compared between the two groups. Between the two groups, except for the presence or absence of formal music therapy, the rest of treatment had no significant difference and was matched by age, gender, and injury types. In 40 cases of traumatic brain injury patients, the GCS value increased in the music group after treatment when compared to the control group. The difference between the two groups was significant (p < 0.05). The quantitative EEG value (δ+θ/α+β value) of music group values were decreased after treatment, and the difference was significant compared with the control group (p < 0.05). Through the quantitative EEG (δ+θ/α+β value) and the GCS observation score, music therapy in patients with craniocerebral trauma coma has obviously an effect on promoting to regain consciousness. The quantitative EEG (δ+θ/α+β value) can be used as an objective index to evaluate the state of brain function.

Work-related stress (WRS) is known to cause ill-health and decreased productivity. Work in the education sector is thought to be particularly stressful. Few studies have considered risk factors for WRS and health in head teachers. To investigate health in head teachers in West Sussex. To determine personal risk factors most likely to predict cases of WRS and of poor health in head teachers. A cross-sectional study, in a population of 290 head teachers and principals of colleges of further education, using a validated questionnaire, 'a short stress evaluation tool' (ASSET) and additional questions derived from earlier studies. Results were compared with the ASSET database 'norm' groups: a general population of workers (GPN) group and a group of managers and professionals (MPN). 'Caseness' was defined as respondents who felt work was 'very or extremely stressful'. Head teachers had poor physical and mental health compared to the GPN group. Psychological well-being, particularly of females and primary head teachers was worse than a comparative group of managers and professionals. Teaching<5 h/week was a significant predictor of caseness and being female was the main risk factor for poor psychological well-being. Prevalence of self-reported stress in head teachers in West Sussex is high. Female head teachers had worse health outcomes. Our study identified possible personal risk factors predicting WRS and/or poor health in head teachers.

The objective of this study was to compare the effects of image-guided hypofractionated radiotherapy and conventional fractionated radiotherapy on non-small-cell lung cancer (NSCLC). Fifty stage- and age-matched cases with NSCLC were randomly divided into two groups (A and B). There were 23 cases in group A and 27 cases in group B. Image-guided radiotherapy (IGRT) and stereotactic radiotherapy were conjugately applied to the patients in group A. Group A patients underwent hypofractionated radiotherapy (6–8 Gy/time) three times per week, with a total dose of 64–66 Gy; group B received conventional fractionated radiotherapy, with a total dose of 68–70 Gy five times per week. In group A, 1-year and 2-year local failure survival rate and 1-year local failure-free survival rate were significantly higher than in group B (P<0.05). The local failure rate (P<0.05) and distant metastasis rate (P>0.05) were lower in group A than in group B. The overall survival rate of group A was significantly higher than that of group B (P=0.03), and the survival rate at 1 year was 87% vs 63%, (P<0.05). The median survival time of group A was longer than that of group B. There was no significant difference in the incidence of complications between the two groups (P>0.05). Compared with conventional fractionated radiation therapy, image-guided hypofractionated stereotactic radiotherapy in NSCLC received better treatment efficacy and showed good tolerability.

Cesarean section (CS) is an independent risk factor for placenta accreta. Some researchers think that the timing of primary cesarean delivery is associated with placenta accreta in subsequent pregnancies. The aim of this study was to investigate the risk of placenta accreta following primary CS without labor, also called primary elective CS, in a pregnancy complicated with placenta previa. A retrospective, single-center, case-control study was conducted at Peking University Third Hospital. Relevant clinical data of singleton pregnancies between January 2010 and September 2017 were recorded. The case group included women with placenta accreta who had placenta previa and one previous CS. Control group included women with one previous CS that was complicated with placenta previa. Maternal age, body mass index, gestational age, fetal birth weight, gravity, parity, induced abortion, the rate of women received assisted reproductive technology, other uterine surgery, and primary elective CS were analyzed between the two groups. The rate of primary elective CS (90.1% vs. 69.9%, P < 0.001) was higher, and maternal age was younger (32.7 ± 4.7 years vs. 34.6 ± 4.0 years, P < 0.001) in case group, compared with control group. Case group also had higher gravity and induced abortions compared with the control group (both P < 0.05). Primary CS without labor was associated with significantly increased risk of placenta accreta in a subsequent pregnancy complicated with placenta previa (odds ratio: 3.32; 95% confidential interval: 1.68-6.58). Women with a primary elective CS without labor have a higher chance of developing an accreta in a subsequent pregnancy that is complicated with placenta previa.

The purpose of this study was to determine the frequency and distribution of cytogenetically abnormal miscarriages in couples with spontaneous abortions (SA) or recurrent miscarriages (RM). Karyotyping of specimens from 164 abortuses with SA and 86 abortuses with RM was successfully performed according to the standard cytogenetic methods using G-banding technique. Among the total 164 cases of SA group, 81 (49.4%) were euploid and the rest (83, 50.6%) showed chromosomal abnormalities. In RM(≥2) and RM(≥3) group, 31 (36.0%)/27 (34.6%) cases were euploid and 55 (64.0%)/51(65.4%) cases were abnormal, respectively. A statistically significant difference was found in the rate of cytogenetic abnormality between SA and RM groups (P<0.05). In all groups, women with advanced maternal age (≥35 years) had a higher rate of chromosome anomalies compared with women younger than age 35 (normal:abnormal = 32.4%:67.6% for ≥35 years and 53.8%:46.2% for <35 years in SA; 19.2%:80.8%/21.7%:78.3% for ≥35 years and 43.3%:56.7%/40.0%:60.0% for <35 years in RM(≥2) and RM(≥3), respectively; P<0.05). In SA group, an increase of normal karyotypes was noted with increased gestational age (<10 week, 38.0%; 10-15 week, 53.5%; 16-20 week, 65.7%). In RM group, most of cases were in <10 week and the frequency of trisomies with chromosomes 1 to 10 were increased compared with that of SA. There was a statistically significant difference in the frequency and distribution of chromosomal abnormalities between SA and RM groups. Our results will provide useful information for diagnosis and genetic counseling of patients with SA or RM.

To evaluate the hypothesis that assigning grades to magnetic resonance imaging (MRI) findings of suspected placenta accreta will correlate with hemorrhagic outcomes. We chose a single-center, retrospective, observational design. Nulliparous or multiparous women who had antenatal placental MRI performed at a tertiary level academic hospital were included. Cases with antenatal placental MRI were included and compared with cases without MRI performed. Two radiologists assigned a probability score for accreta to each study. Estimated blood loss and transfusion requirements were compared among groups by the Kruskal-Wallis H test. Thirty-five cases had placental MRI performed. MRI performance was associated with higher blood loss compared with the non-MRI group (2600 [1400-4500]mL vs 900[600-1500]mL, P<.001). There was no difference in estimated blood loss (P=.31) or transfusion (P=.57) among the MRI probability groups. In cases of suspected placenta accreta, probability scores for antenatal placental MRI may not be associated with increasing degrees of hemorrhage. Continued research is warranted to determine the effectiveness of assigning probability scores for antenatal accreta imaging studies, combined with clinical indices of suspicion, in assisting with antenatal multidisciplinary team planning for operative management of this morbid condition.

To describe the epidemiology of pertussis in the Waikato region of New Zealand between 2000 and 2009, and to identify any differences in case characteristics between epidemic and non-epidemic periods. Waikato pertussis notification data for the period 1 January 2000 to 31 December 2009 was analysed to identify any trends in the rates and distribution of key variables. Characteristics of case notifications were compared between an identified epidemic and non-epidemic period. Pertussis notification rates in the Waikato region were higher than national rates but followed a similar yearly pattern. Epidemics were identified in the years 2000 and 2004. The age distribution of pertussis cases changed over the decade with an increasing percentage in older age groups. Notification rates were higher in Europeans than Maori and in the least deprived NZDep group compared to the most deprived. In contrast, hospitalisation rates were higher in Maori than Europeans and in the most deprived NZDep groups. No clear differences in case characteristics were identified between an epidemic and non-epidemic period. The epidemiology of pertussis in Waikato is similar to that reported elsewhere in New Zealand. Further studies are required to clearly identify whether there are differences in case characteristics between epidemic and non-epidemic periods.

The prevalence and type distribution of human papillomavirus (HPV) in cervical cancer and cervical intraepithelial neoplasia (CIN) in Jiangsu, China was investigated. A total of 93 cases with cervical cancer and 176 CINII-III tissue samples were obtained from women undergoing biopsy or surgery. The 1047 exfoliated cervical cell samples were collected with cervical brush in physical examination women. HPV DNA and typing were examined by polymerase chain reaction (PCR) and gene-chip. The results showed that HPV DNA was detected in 82 cases with cervical cancer (88.17%), HPV 16 being detected in 65 (69.89%) cases, HPV 18 in 12 (12.90%) cases, HPV 33 in 10 (10.75%) cases, HPV 31 in 4 (4.30%) cases, and HPV 45 in 3 (3.23%) cases. HPV DNA was detected in 154 cases with CINII-III (87.50%), HPV 16 being detected in 92 (52.27%) cases, HPV 18 in 50 (28.41%) cases, HPV 33 in 25 (14.21%) cases, HPV 58 in 25 (14.21%) cases, and HPV 31 in 20 (11.36%) cases. About 20.43% cervical cancer and 38.64% CINII-III specimens exhibited multiple infections (p < 0.01). The total positive rate, single infection and mixed infection rate of the CINII-III and SCC group all had a significant difference (p < 0.05) when compared with the normal cells group. The total positive rate, single infection rate and mixed infection rate of CINII-III group did not show significant difference (p > 0.05) when compared with SCC group. CINII-III and SCC had all intimate relation with HPV infection. The high prevalence of HPV 16, 18, 33, 31 and 58 in Jiangsu (China) deserves more attention, as it has important implications for the successful use of HPV vaccine and choice of diagnostic methods.

Compare syphilis investigation yield among patient groups using number needed to interview. To increase investigation efficiency. Retrospective review of North Carolina 2015 syphilis investigations, using the number of cases needed to interview (NNTI) and the total number of cases and contacts needed to interview (TNTI) to compare yield of new syphilis and human immunodeficiency virus diagnoses between patient groups. We reviewed 1646 early syphilis cases and 2181 contacts; these yielded 241 new syphilis cases (NNTI, 6.9; TNTI, 16.4) and 38 new human immunodeficiency virus cases (NNTI, 43). Interviews of women (prevalence difference [PD] = 6%, 95% confidence interval [CI], 12-16), patients <30 years old (PD = 5%, 95% CI, 1-8), and patients with titer >1:16 (PD = 5%, 95% CI, 1-9) yielded more new syphilis cases in our adjusted model; no other patient factors increased investigation yield. The NNTI and TNTI are useful measures of efficiency. Prioritizing early syphilis investigation by gender, rapid plasmin reagin titer, and age provides small increases in efficiency; no other factors increased efficiency.

One of the common findings encountered by the clinician at the end of orthodontic treatment is the apical root resorption. Root resorption occurs to various degrees. A severe form of root resorption is characterized by shortening of root for more than 4 mm or more than one-third of the total tooth length. A low incidence rate of resorption is observed based on radiographic findings for the diagnosis of root resorption, panoramic radiography, and periapical radiography. Hence, we evaluated the accuracy of panoramic radiographic films for assessing the root resorption in comparison with the periapical films. This study included the assessment of all the cases in which pre- and post-treatment radiographs were available for analysis of the assessment of the amount of root resorption. Complete records of 80 patients were analyzed. Examination of a total of 900 teeth was done. Mean age of the patients in this study was 21 years ranging from 11 to 38 years. The majority of the patients in the present study were females. All the treatments were carried out by registered experienced orthodontists having minimum experience of more than 10 years. All the cases were divided into two study groups. Group I comprised panoramic radiographic findings, while group II consisted of periapical radiographic findings. For the measurement of crown portion, root portion, and the complete root length, magnification loops of over 100 powers with parallax correction with inbuilt grids were used. Assessment of the tooth length and the crown length was done by the same observers. All the results were analyzed by Statistical Package for the Social Sciences software version 6.0. Maximum amount of root resorption was observed in case of maxillary central incisors and canines among group I and II cases respectively. However, nonsignificant difference was obtained while comparing the mean root resorption in relation to maxillary incisors and canines among the two study groups. While comparing the overall value of root resorption among the two study groups, a significant difference was obtained. The maximum value of tooth length in both the groups was observed in cases of maxillary canines. Significant differences were observed while comparing the tooth length of various teeth among the two study groups. Among the deviated forms of root shape, dilacera-tion was the most common form of root shape detected in both the study groups. Periapical radiographs are more efficient in the assessment of the shape and resorption of the root. Thorough evaluation of periapical radiographs is necessary for detection of even minute levels of root resorption.

Summary Background Our main objective was to evaluate the association between autoimmune thyroiditis and the Delphian lymph node during different stages of thyroiditis. Material/Methods The relationships between the ultrasonography (US) results of thyroiditis and characteristics of the Delphian lymph node in different stages of AT were evaluated. Thyroid hormone and antibody levels were assessed. A total of 126 patients were divided into four groups according to the thyroid US findings: Group 1: control cases; Group 2: indeterminate cases; Group 3: established thyroiditis cases; Group 4: advanced-late stage thyroiditis cases. Indeterminate cases attended a 1-year follow-up, and the cases with a sonographic finding matching thyroiditis formed Group 2. Results The rate of Delphian lymph node presence in Group 4 was significantly higher than in Groups 1 and 2 (p<0.01). In addition, its presence was significantly higher in Group 3 than in Group 1 (p<0.05). Although there was a difference in Delphian lymph node presence between Groups 2 and 3, it was not significant (p=0.052), nor was there a significant difference between Groups 1 and 2 (p>0.05). Both the long and short axis measurements were significantly higher in Groups 2, 3, and 4 compared to those in the control group. However, the same increase was not observed in the long/short axis ratio. Conclusions Both the presence and dimensions of the Delphian lymph node were highly correlated with the progress of autoimmune thyroiditis. Evaluating the Delphian lymph nodes might prevent missing a diagnosis of autoimmune thyroiditis. PMID:26985243

To study the ultra structural changes in bladder musculature in cases of BPE and their clinical relevance. In this descriptive longitudinal, controlled, observational study patients were enrolled into three groups, group 1, group 2A and group 2B. Control group (group-1) consisted of age matched normal male patients, who underwent surveillance or diagnostic cystoscopy for microscopic hematuria or irritative symptoms. Case group (group-2) comprised of patients with BPE, undergoing TURP. Case group (group-2) was further classified into: Category 2A (patients not on catheter) and cat-egory 2B (patients on catheter). All relevant clinical parameters like IPSS, prostate size, Qmax, PVR were recorded. Cystoscopy and bladder biopsy were performed in all patients. Various ultrastructural parameters like myocytes, fascicular pattern, interstitial tissue, nerve hypertrophy and cell junction pattern were analyzed under electron microscope and they were clinically correlated using appropriate statistical tests. Control group had significant difference as compared to case group in terms of baseline parameters like IPSS, flow rate and prostate size, both preoperatively and postoperatively, except for PVR, which was seen only preoperatively. There was statistically significant difference in ultrastructural patterns between case and control group in all five electron microscopic patterns. However, no significant difference was found between the subcategories of case groups. BPE is responsible for ultra structural changes in detrusor muscle and these changes remain persistent even after TURP. Nerve hypertrophy, which was not thoroughly discussed in previous studies, is also one of the salient feature of this study. Copyright® by the International Brazilian Journal of Urology.

Free-flap reconstruction via a retroauricular approach (RRA) after robot-assisted neck dissection (RAND) could have cosmetic benefits. This study aimed to compare the surgical outcomes of free-flap reconstruction via a RRA and via a transcervical approach in head and neck cancer. For this matched case-control study, 50 patients with head and neck cancer requiring free-flap reconstruction were divided into two groups: those reconstructed via a RRA group and those reconstructed via a transcervical approach (RTA group). The total operation time for free-flap reconstruction, the flap survival rate, the length of the hospital stay, the complications, and the scar satisfaction scores were compared between the two groups. The RRA group comprised 25 patients, and the RTA group had 25 patients. The mean operation time for reconstruction was 288 ± 77 min in the RRA group and 250 ± 98 min in the RTA group (p = 0.132). Flap failure occurred for two patients in the RRA group (8 %) and for one patient in the RTA group (4 %) (p = 1.000). The mean hospital stay was 21 ± 18 days in the RRA group and 23 ± 14 days in the RTA group (p = 0.669). The complications were comparable between the two groups. However, the overall scar satisfaction was significantly higher in the RRA group (p = 0.000). For patients with head and neck cancer, RRA has better cosmetic outcomes than RTA. The RRA approach could be used for select patients who undergo RAND and prefer to avoid a visible anterior neck scar.

The use of propofol, as compared to barbiturates (e.g. thiopental), for short surgical procedures has been associated with more rapid recovery from the procedure. Propofol, an intravenous anesthetic drug, is frequently used as an adjunct to transvaginal oocyte retrieval but little is known about its effects upon fertilization, embryo development, and pregnancy rate when used drug the for induction of general anesthesia. This study was conducted to compare the outcome of assisted reproductive technology (ART) with the use of propofol versus thiopental sodium for the induction of general anesthesia during oocyte retrieval. In this retrospective study, 92 cases of infertile patients who underwent oocyte retrieval under the induction of general anesthesia with, respectively, either propofol (Group I, 72 cases) or thiopental sodium (Group II, 20 cases) were compared for fertilization rate, cleavage rate, and pregnancy rate. The fertilization rate was 68.9% for Group I and 66.7% for group II (p = 0.614). The cleavage rate was 96.5% for Group I and 94.8% for Group II (p = 0.294). The rate of good embryo grading and poor embryo grading was, respectively, 85.1% and 14.9% for Group I, versus 85.7% and 14.3% for Group II (p = 0.887). The pregnancy rate was 30.5% for Group I and 20.0% for Group II (p = 0.354). The implantation rate and abortion rate was, respectively, 9.1% and 18.2% for Group I versus 7.2% and 25.0% for Group II (implantation rate, p = 0.590; abortion rate, p = 0.600). There were no significant differences between these two groups for fertilization rate, cleavage rate, pregnancy rate, implantation rate and abortion rate. We suggest cautious use of propofol for the procedure of oocyte retrieval despite its associated more rapid post-operative recovery including less nausea/vomiting.

To investigate human coronaviruses (HCoVs) infection in children with acute lower respiratory tract infection(ALRTI)and to explore the clinical features of ALRTI caused by HCoVs in children. Totally 4 371 children with clinical diagnosis of ALRTI during the period from March 2007 to February 2015 seen in Beijing Children's Hospital were recruited into this study. Patients were divided into 4 groups by age, including 1 890 cases in < 1 year group, 788 cases in 1-3 years group, 553 cases in 3-6 years group, 1140 cases in ≥6 years group. One nasopharyngeal aspirate specimen was collected from each patient. RT-PCR methods were applied to detect 9 common respiratory viruses including HCoVs (including HCoV-OC43, HCoV-229E, HCoV-NL63 and HCoV-HKU1), respiratory syncytial virus (RSV) and so on. Clinical features of ALRTI with single HCoVs infection were analyzed and compared with hospitalized ALRTI cases with single RSV infection in the same period. (1) Totally 2 895 cases were positive for at least one virus in this study in 4 371 ALRTI patients (positive rate 66.23%), in which 147 cases were positive for HCoVs infection (positive rate 3.36%). (2) Positive rates of HCoVs in each year from 2007 to 2014 were 6.11%, 3.79%, 4.69%, 4.31%, 2.38% 2.10%, 0.77% and 2.65%, respectively. The mean positive rates of HCoVs for each month from January to December were 2.53%, 2.12%, 3.63%, 6.68%, 1.53%, 3.77%, 3.92%, 3.00%, 2.15%, 5.26%, 3.01% and 2.80%. (3) Detection results of each subtypes of HCoVs in total 4 371 pediatric ALRTI patients were: 48 cases positive for HCoV-OC43(1.10%), 32 cases positive for HCoV-229E(0.73%), 25 cases positive for HCoV-NL63 (0.57%), 27 cases positive for HCoV-HKU1 (0.62%). (4) Positive rates of HCoVs infection in <1 year group, 1-3 years group, 3-6 years group and ≥ 6 years group were 4.13%, 5.08%, 2.71% and 1.23%, respectively. There were significant differences in positive rates of HCoV among groups (χ² = 27.218, P<0.01). (5) There were 16 hospitalized cases with single infection of HCoVs in this study, of which 12 cases were diagnosed as bronchopneumonia, 3 cases developed acute laryngeal obstruction, 2 cases had acute bronchial asthma attack. Common clinical manifestations included cough (14 cases), gasping (13 cases), dyspnea (9 cases), fever (6 cases), hoarseness (4 cases), laryngeal stridor (4 cases) and abnormality on chest X-ray (including fuzzy lung texture, patchy shadow and consolidation) (12 cases). (6) There were no significant differences in the incidence of clinical manifestations (including cough, gasping, dyspnea, fever and abnormality on chest X-ray), complications (including respiratory failure, myocardial damage, and acute bronchial asthma attack) and mechanical ventilation between hospitalized ALRTI patients with single HCoV infection and 193 patients with single RSV infection in the same period. HCoVs are pathogens of ALRTI in children, The overall positive rate of HCoVs was 3.36% in this study. The clinical manifestations and severity of ALRTI caused by single HCoVs was comparable to that of ALRTI with single RSV infection in children.

Objective. To determine the degree to which 3 different educational interventions enhance cultural competency in pharmacy students. Methods. Students were equally divided among a simulated-patient activity group, a written case-scenarios group, and a formal lecture group. Mean scores for pre- and post-intervention cultural self-assessment surveys were compared. Results. In the simulation group, there were significant positive changes in the cultural skills and cultural desire components; in the case-scenario group, there was a significant positive change in the cultural awareness component; and in the lecture group, there were significant positive changes in the cultural skills and cultural empathy components. With respect to the cultural skills component, there was greater post-intervention improvement in the simulation and lecture groups than in the case-scenario group. Conclusions. There were significant positive changes within each group, indicating that ideologies and behaviors may be altered based on the educational intervention received. However, a 1-hour practicum may not be sufficient to enhance cultural competency. PMID:23716744

To evaluate cytopathological changes in epithelial cells of the oral mucosa of patients with oral lichen planus (OLP) compared with patients without OLP. Swabs were collected from the oral mucosa of 20 patients with OLP (case group) and 20 patients without OLP (control group) using liquid-based cytology. After Papanicolaou staining, the smears were characterized based on Papanicolaou classification and degree of maturation. Nuclear area (NA) measurements, cytoplasmic area (CA) measurements, and the NA/CA ratio were determined from 50 epithelial cells per slide. For quantification of argyrophilic nucleolar organizer regions (AgNORs), the smears were stained with silver nitrate, and the number of AgNORs was counted in 100 cells. In both groups, there was a predominance of Papanicolaou Class I nucleated cells in the superficial layer. The average values of NA (p>0.05) and CA (p=0.000) were greater in the case group (NA=521.6, CA=22,750.3) compared with the control group (NA=518.9, CA=18,348.0). The NA/CA ratio was 0.025 for the case group and 0.031 for the control group (p=0.004). There was no significant difference between the mean AgNORs values of both groups (p>0.05). The oral mucosa of patients with OLP exhibited significant cytomorphometric changes. However, there was no evidence of malignancy. Copyright © 2016 Elsevier GmbH. All rights reserved.

To compare the effect of Scientific Exercises Approach to Scoliosis (SEAS) exercises with "usual care" rehabilitation programmes in terms of the avoidance of brace prescription and prevention of curve progression in adolescent idiopathic scoliosis. Prospective controlled cohort observational study. Seventy-four consecutive outpatients with adolescent idiopathic scoliosis, mean 15 degrees (standard deviation 6) Cobb angle, 12.4 (standard deviation 2.2) years old, at risk of bracing who had not been treated previously. Thirty-five patients were included in the SEAS exercises group and 39 in the usual physiotherapy group. The primary outcome included the number of braced patients, Cobb angle and the angle of trunk rotation. There were 6.1% braced patients in the SEAS exercises group vs 25.0% in the usual physiotherapy group. Failures of treatment in the worst-case analysis were 11.5% and 30.8%, respectively. In both cases the differences were statistically significant. Cobb angle improved in the SEAS exercises group, but worsened in the usual physiotherapy group. In the SEAS exercises group, 23.5% of patients improved and 11.8% worsened, while in the usual physiotherapy group 11.1% improved and 13.9% worsened. These data confirm the effectiveness of exercises in patients with scoliosis who are at high risk of progression. Compared with non-adapted exercises, a specific and personalized treatment (SEAS) appears to be more effective.

There is a need to provide more efficient surgical training methods for orthopaedic residents. E-learning could possibly increase resident surgical preparedness, confidence, and comfort for surgery. Using closed reduction and pinning of pediatric supracondylar humeral fractures as the index case, we hypothesized that e-learning could increase resident knowledge acquisition for case preparation in the operating room. An e-learning surgical training module was created on the Computer Enhanced Visual Learning platform. The module provides a detailed and focused road map of the procedure utilizing a multimedia format. A multisite prospective randomized controlled study design compared residents who used a textbook for case preparation (control group) with residents who used the same textbook plus completed the e-learning module (test group). All subjects completed a sixty-question test on the theory and methods of the case. After completion of the test, the control group then completed the module as well. All subjects were surveyed on their opinion regarding the effectiveness of the module after performing an actual surgical case. Twenty-eight subjects with no previous experience in this surgery were enrolled at four academic centers. Subjects were randomized into two equal groups. The test group scored significantly better (p < 0.001) and demonstrated competence on the test compared with the control group; the mean correct test score (and standard deviation) was 90.9% ± 6.8% for the test group and 73.5% ± 6.4% for the control group. All residents surveyed (n = 27) agreed that the module is a useful supplement to traditional methods for case preparation and twenty-two of twenty-seven residents agreed that it reduced their anxiety during the case and improved their attention to surgical detail. E-learning using the Computer Enhanced Visual Learning platform significantly improved preparedness, confidence, and comfort with percutaneous closed reduction and pinning of a pediatric supracondylar humeral fracture. We believe that adapting such methods into residency training programs will improve efficiency in surgical training.

Doctor of physical therapy (DPT) student learning about role delineation of physical therapist assistants (PTAs) is essential to ethical and legal practice. Survey assessment of three DPT student cohorts compared collaborative interprofessional case-based learning with PTA students to traditional curriculum delivery strategies. Control cohorts were assessed one time. The intervention group was assessed pre-intervention, immediately post-intervention, and after completing a full-time clinical experience. The case-based learning covered 46% of survey content, allowing for the assessment of content-specific material and potential learning through collaboration. Following the educational intervention, the intervention group improved significantly in areas inside and outside the case-based study content, outscoring both control groups on 25-34% of the survey items. Following the clinical experience, the intervention group declined answer accuracy for patient evaluation and treatment implementation, suggesting unlearning. Improvement in the administrative section was observed after the clinical experience. Perceptions of the tasks within the PTA role were diminished while tasks outside the scope of practice appeared clarified following the clinical experience. While case-based collaborative intraprofessional learning proves effective in student learning about the PTA role, changes following the clinical experience raise questions about the influence of the clinical environment on learning and the practical application of recently learned knowledge.

To analyze the efficacy of different surgical methods in treating palmar hyperhidrosis and the compensatory hyperhidrosis after surgery and to observe the efficacy of "Energy-boosting and Yin-nourishing anti-perspirant formula" on postsurgical hyperhidrosis patients. Two-hundred patients were randomly assigned to groups A (Chinese and Western medicine, T4 transection plus "Energy-boosting and Yin-nourishing anti-perspirant formula") and B (Western medicine, T4 transection). The surgical efficiency, recurrence rate, compensatory hyperhidrosis, and the long-term life quality were compared. Another 100 cases (group C, T2 transection) were analyzed as a control group. After surgery, the palmar hyperhidrosis and armpit sweating were relieved in all the three group patients and in 34 % of patients combined with plantar hyperhidrosis, the symptoms were relieved. Transient palmar hyperhidrosis was found in three cases at day 2 to day 5 postoperatively. One case of Horner's syndrome and one case recurrence were found in group C patients. The compensatory sweating of various degrees occurred in all the three groups. There were 25, 24, and 43 cases in groups A, B, and C, respectively. There is a significant difference between groups C, A, and B. The compensatory sweating in 13 cases of group A and four cases of group B had different degrees of improvement in the follow-up 6 months after surgery. There is a significant difference. Thoracoscopic bilateral T4 sympathetic chain and the Kuntz resection are the optimized surgical treatments for the palmar hyperhidrosis. "Energy-boosting and Yin-nourishing anti-perspirant formula" is effective in treating the postoperative compensatory sweating.

To estimate risk of colorectal cancer (CRC) for first-degree relatives of CRC cases based on CRC molecular subtypes and tumour pathology features. We studied a cohort of 33,496 first-degree relatives of 4853 incident invasive CRC cases (probands) who were recruited to the Colon Cancer Family Registry through population cancer registries in the USA, Canada and Australia. We categorised the first-degree relatives into four groups: 28,156 of 4095 mismatch repair (MMR)-proficient probands, 2302 of 301 MMR-deficient non-Lynch syndrome probands, 1799 of 271 suspected Lynch syndrome probands and 1239 of 186 Lynch syndrome probands. We compared CRC risk for first-degree relatives stratified by the absence or presence of specific tumour molecular pathology features in probands across each of these four groups and for all groups combined. Compared with first-degree relatives of MMR-proficient CRC cases, a higher risk of CRC was estimated for first-degree relatives of CRC cases with suspected Lynch syndrome (HR 2.06, 95% CI 1.59 to 2.67) and with Lynch syndrome (HR 5.37, 95% CI 4.16 to 6.94), but not with MMR-deficient non-Lynch syndrome (HR 1.04, 95% CI 0.82 to 1.31). A greater risk of CRC was estimated for first-degree relatives if CRC cases were diagnosed before age 50 years, had proximal colon cancer or if their tumours had any of the following: expanding tumour margin, peritumoral lymphocytes, tumour-infiltrating lymphocytes or synchronous CRC. Molecular pathology features are potentially useful to refine screening recommendations for first-degree relatives of CRC cases and to identify which cases are more likely to be caused by genetic or other familial factors.

To investigate the clinical presentation, operative outcome, and incidence of malignancy in postmenopausal women who were diagnosed with adnexal torsion. Retrospective cohort study (Canadian Task Force classification II-2). Tertiary university-affiliated hospital. Postmenopausal women diagnosed with adnexal torsion between 1995 and 2014 (study group) were reviewed and compared with 220 premenopausal patients diagnosed with adnexal torsion during the same time period. Demographic data, clinical signs and symptoms, and intra- and postoperative characteristics were compared between the 2 groups. During the study period 44 postmenopausal women were diagnosed with adnexal torsion. Continuous dull pain was the most common presenting symptom in the postmenopausal group (57%), whereas acute-onset sharp pain was the predominant symptom in the premenopausal group (86%). The time interval from admission to surgery was significantly longer in the postmenopausal group (24 vs 6 hours, p < .001). Laparoscopic surgery was performed in 84.5% of the cases in the premenopausal group, whereas it was carried out in only 50% of cases in the postmenopausal group (p < .001). Four women in the postmenopausal group were diagnosed with malignancy, whereas only 1 case of malignancy was found in the premenopausal group (9% vs .4%, respectively; p = .003). Adnexal torsion in postmenopausal women is an uncommon event with a unique presentation. Because ovarian malignancy is not an uncommon finding in this group of patients, preparation for more extensive surgery should be contemplated. Copyright © 2016 AAGL. Published by Elsevier Inc.

To assess levels of vitamin D and of immunoglobulin G subclasses in children and adolescents with type 1 Diabetes Mellitus with or without autoimmune thyroiditis. Among 213 patients with type 1 diabetes, the cases with thyroid-specific autoantibodies formed Group 1 [n=19, M/F: 7/12, median age 13 years (10.1-14.7)]. Nineteen age-, gender-, and diabetes duration-matched cases with type 1 diabetes without any other systemic disease were designated as controls [Group 2, M/F: 7/12, median age 12.9 years (10.5-14.9)]. Levels of thyroid hormones, vitamin D, total IgG and IgG subclasses, as well as IgG subclasses/total IgG ratios were similar between the groups. Five cases (26%) in Group 1 had IgG4 levels > + 2 SDS, whereas there were no such cases in Group 2 (p=0.046). These five patients had similar clinical features but higher median IgG4 levels and IgG4/Total IgG ratios compared to the subjects with IgG4 levels < + 2 SDS in Group 1 and Group 2. There was no difference of vitamin D levels between the groups. Only a small percentage of patients with type 1 diabetes also having autoimmune thyroiditis had elevated serum IgG4 levels, revealing the heterogeneity of autoimmune thyroiditis and existence of IgG4 thyroiditis in the pediatric age group. Total IgG, the other IgG subclasses, and vitamin D levels did not differ in patients with autoimmune thyroiditis and type 1 diabetes compared to those suffering only from type 1 diabetes.

This study was carried out in a Anti-Retroviral Therapy Clinic and TB center of a tertiary level hospital to find out socio-demographic correlates of HIV/TB individuals and risk factors of HIV/TB co-infection in Indian context. It is a case-control study comprising 420 subjects, 3 groups of 140 each. For a case group of HIV-TB co-infected subjects, two control groups, one comprising HIV patients (not having TB), and the other TB patients (not having HIV). Majority 267 (63.6%) males, 100 (71.4%) in case group (HIV/ TB), 74 (52.9%) in control group 1 (TB) and 93 (66.4%) in control group 2 (HIV). Mean (+/-SD) age of case-group was 34.91 (+/- 8.57) years. New TB cases were 213 (76.1%), more among control-group 1, compared to case-group. Multivariate analysis showed that risk of co-infection was 1.94 times higher among individuals aged >35 years. Difference statistically significant amongst those who were not on ART than who were on ART (p < 0.001). Those with CD4 counts <200 had 1.85 times risk of TB. Smokers had 1.92 times risk of TB. Co-infection higher in males, in age group 35-44 years, urban area, lower educational status and lower socioeconomic class. Current history of smoking significantly associated with co-infection. HIV status during TB infection was detected in 1/4th of study subjects. History of TB symptoms in family significantly associated with co-infection.

Involvement of community mental health consumers in mental health decision making has been consistently associated with improvements in health outcomes. Electronic decision support systems (EDSSs) that support both consumer and provider decision making may be a sustainable way to improve dyadic communication in a field with approximately 50% workforce turnover per year. This study examined the feasibility of such a system and investigated proximal outcomes of the system's performance. A cluster randomized design was used to evaluate an EDSS at three urban community mental health sites. Case managers (N=20) were randomly assigned to the EDSS-supported planning group or to the usual care planning group. Consumers (N=80) were assigned to the same group as their case managers. User satisfaction with the care planning process was assessed for consumers and case managers (possible scores range from 1 to 5, with higher summary scores indicating more satisfaction). Recall of the care plan was assessed for consumers. Linear regression with adjustment for grouping by worker was used to assess satisfaction scores. A Wilcoxon rank-sum test was used to examine knowledge of the care plan. Compared with case managers in the control group, those in the intervention group were significantly more satisfied with the care planning process (mean ± SD score=4.0 ± .5 versus 3.3 ± .5; adjusted p=.01). Compared with consumers in the control group, those in the intervention group had significantly greater recall of their care plans three days after the planning session (mean proportion of plan goals recalled=75% ± 28% versus 57% ± 32%; p=.02). There were no differences between the clients in the intervention and control groups regarding satisfaction. This study demonstrated that clients can build their own care plans and negotiate and revise them with their case managers using an EDSS.

The aim of this study was to investigate whether the use of fenoterol, a beta2-adrenergic agonist, was associated with multiple sclerosis (MS) risk by conducting a total population-based case-control study in Taiwan. A total of 578 patients with newly diagnosed MS who had a severely disabling disease (SDD) certificate between January 1, 2002 and December 1, 2008 comprised the case group. These cases were compared with 2890 gender-, age-, residence-, and insurance premium-matched controls. Fenoterol use was analyzed using a conditional logistic regression model that controlled for asthma, chronic obstructive pulmonary disease (COPD), salbutamol and steroid use. Compared with the group of people who did not use fenoterol, the adjusted odds ratios were 0.67 (95% confidence interval (CI) = 0.48-0.93, p = 0.016) for the group prescribed fenoterol below 2.25 cumulative defined daily dose (cDDD) and 0.49 (95% CI = 0.33-0.71, p < 0.001) for the group with a cumulative fenoterol use of more than 2.25 cDDD. The dose-response relationship was similar within the non-asthma patients. The associations were similar between males and females, but differences between age groups were observed. The results of this study suggest that fenoterol use may reduce the risk of MS. © The Author(s), 2014.

The aim of the study was to compare the acute outcomes of Absorb bioresorbable vascular scaffolds (BVS) and second-generation drug-eluting stent (DES) implantation in routine clinical practice. There is a paucity of data regarding BVS use in a real-world patient population. The study population comprised 40 consecutive patients who underwent percutaneous coronary intervention (PCI) with BVS implantation at a tertiary-care center in New York, New York between July and December of 2016. An optimal implantation technique including adequate lesion preparation, mandatory postdilation, and optical coherence tomography (OCT) imaging was used in all cases. De novo lesions treated with BVS were compared to lesions treated with DES matched by OCT calcium arc, scaffold/stent size, use of atherectomy device, and lesion postdilation. Acute lumen gain, minimal device area, malapposition, eccentricity, and symmetry index were assessed using OCT. We analyzed OCT images of 40 BVS cases and 40 matching DES cases from 35 and 40 patients, respectively. Compared to the DES group, the BVS group demonstrated similar acute lumen gain, minimal scaffold/stent area, eccentricity index, and symmetry index after PCI. There were fewer malapposed struts detected after BVS implantation; however, malapposition distance and length were not different between the groups. BVS implantation in a real-world patient population with optimal implantation technique resulted in similar stent expansion and better strut apposition compared to DES implantation.

To analyze the interrelationship between incisor width, deviations in the dentition and available space in the dental arch in palatally and labially located maxillary ectopic canine cases. Size: On dental casts from 69 patients (mean age 13 years 6 months) the mesiodistal widths of each premolar, canine and incisor were measured and compared with normal standards. Dental deviations: Based on panoramic radiographs from the same patients the dentitions were grouped accordingly: Group I: normal morphology; Group IIa: deviations in the dentition within the maxillary incisors only; Group IIb: deviations in the dentition in general. Descriptive statistics for the tooth sizes and dental deviations were presented by the mean and 95% confidence limits for the mean and the p-value for the T-statistic. Space: Space was expresses by subtracting the total tooth sizes of incisors, canines and premolars from the length of the arch segments. Size of lateral maxillary incisor: The widths of the lateral incisors were significantly different in groups I, IIa and IIb (p=0.016) and in cases with labially located ectopic canines on average 0.65 (95% CI:0.25-1.05, p=0.0019) broader than lateral incisors in cases with palatally located ectopic canines. Space: Least available space was observed in cases with labially located canines. The linear model did show a difference between palatally and labially located ectopic canines (p=0.03). Space related to deviations in the dentition: When space in the dental arch was related to dental deviations (groups I, IIa and IIb), the cases in group IIb with palatally located canines had significantly more space compared with I and IIa. Two subgroups of palatally located ectopic maxillary canine cases based on registration of space, incisor width and deviations in the morphology of the dentition were identified.

Background: Providing community-based mental health services is crucial and is an agreed plan between the Iranian Mental Health Office and the Regional Committee for the Eastern Mediterranean (affiliated with WHO). The aim of this study was to determine the effectiveness of home-visit clinical case-management services on the hospitalization rate and other clinical outcomes in patients with severe mental illness. Methods: A total of 182 patients were randomly allocated into three groups, namely, home-visit (n=60), telephone follow-up (n=61) and as-usual care (n=61) groups. Trained nurses as clinical case-managers provided home-visit services and the telephone follow-up tasks. Hospitalization rate as a measure of recurrence, as well as burden, knowledge, general health condition of caregivers with positive/negative symptoms, satisfaction, quality of life, and social skills of the consumers were assessed as the main and secondary outcomes, respectively. Results: Most clinical variables were improved in both intervention groups compared with the control group. During the one year follow-up, the rate of rehospitalization for the telephone follow-up and as-usual groups were respectively 1.5 and 2.5 times higher than the home-visit group. Conclusion: Trained clinical case-managers are capable of providing continuous care services to patients with severe mental illness. The telephone follow-up services could also have beneficiary outcome for the consumers, their caregivers, and the health system network. PMID:26722141

Syndesmosis injury is common in external-rotation type ankle fractures (ERAF). Trans-syndesmosis screw fixation, the gold-standard treatment, is currently controversial for its complications and biomechanical disadvantages. The purpose of this study was to introduce a new method of anatomically repairing the anterior-inferior tibiofibular ligament (AITFL) and augmentation with anchor rope system to treat the syndesmotic instability in ERAF with posterior malleolus involvement and to compare its clinical outcomes with that of trans-syndesmosis screw fixation. 53 ERAFs with posterior malleolus involvement received surgery, and the syndesmosis was still unstable after fracture fixation. They were randomised into screw fixation group and AITFL anatomical repair with augmentation group. Reduction quality, syndesmosis diastasis recurrence, pain (VAS score), time back to work, Olerud-Molander ankle score and range of motion (ROM) of ankle were investigated. Olerud-Molander score in AITFL repair group and screw group was 90.4 and 85.8 at 12-month follow-up (P>0.05). Plantar flexion was 31.2° and 34.3° in repair and screw groups (P=0.04). Mal-reduction happened in 5 cases (19.2%) in screw group while 2 cases (7.4%) in repair group. Postoperative syndesmosis re-diastasis occurred in 3 cases in screw group while zero in repair group (P>0.05). Pain score was similar between the two groups (P>0.05). Overall complication rate and back to work time were 26.9% and 3.7% (P=0.04), 7.15 months and 5.26 months (P=0.02) in screw group and repair group, respectively. For syndesmotic instability in ERAF with posterior malleolus involvement, the method of AITFL anatomical repair and augmentation with anchor rope system had an equivalent functional outcome and reduction, earlier rehabilitation and less complication compared with screw fixation. It can be selected as an alternative. Copyright © 2016 Elsevier Ltd. All rights reserved.

Laparoscopic sleeve gastrectomy (LSG) has become a popular stand-alone treatment for morbid obesity. However, removal of the gastric specimen could be a challenging step due to its large size relative to the width of the trocar site. We aimed to compare a simplified retrieval technique for extraction of the gastric specimen without an endobag with conventionally performed specimen retrieval using an endobag. A case-control study was conducted recruiting patients undergoing LSG. Patient's demographics, preoperative characteristics, intra-operative, and postoperative variables were compared between the two groups according to the technique of gastric specimen removal. A total of 193 patients (60.6% female) were enrolled into case (n = 100) and control groups (n = 93). Mean ± SD age and BMI of patients were 35.64 ± 11.84 years and 47.28 ± 8.22 Kg/m 2 , respectively with no significant difference between groups. Median (25th, 75th inter-quartile), extraction time was significantly reduced in the non-endobag group compared to the endobag group (3.5 [2.5-4.5] min vs. 6.5 [3.4-8.2] min, p = 0.03).Patients of both groups had similar intra-operative and trocar site complications (hernia and wound infection) (3% for endobag group and 3.3 % for non-endobag group). The median (25-75% [IQR]) LOS was also comparable between endobag and non-endobag patients (3[2-3] vs. 3[2-4] days, p = 0.84). No difference was observed between the two groups for weight loss and comorbidity resolution. Non-endobag technique for gastric specimen retrieval is safe and feasible with substantial saving in operative time and comparable intra-operative and postoperative outcomes to the conventional retrieval technique.

The delivery of a macrosomic infant is a relatively common situation. It can put mother and fetus at high risk. The main maternal complications are the increase in cesarean rates, postpartum hemorrhage and cervicovaginal traumatic lacerations. The main fetal complication is shoulder dystocia increasing the risk of brachial plexus. The objective was to identify risk factors and maternal-fetal complications associated with fetal macrosomia. Comparative retrospective study conducted at Kairouan University Hospital maternity unit in 2010. We compared a group of 820 cases of macrosomic infants to a control group of 800 cases of infants born in the same period of time. During the study period we collected clinical data of 820 macrosomic cases on a total of 7.495 deliveries, corresponding to a total incidence of 10.94%. Several factors predisposing to fetal macrosomia were highlighted: Maternal age> 35 years was present in 28.5% of cases; Maternal obesity was found in 45% of cases; A personal history of macrosomia was noted in 28,8% of cases; Prolonged pregnancies > 41 weeks of amenorrhoea was noted in 35.6% of cases; Multiparity was found in 47% of cases. Maternal complications were essentially postpartum hemorrhage: 71 cases and genital traumas: 24 cases. Perinatal complications were dominated by shoulder dystocia: 27 cases (3.3%). Traumatic postpartum complications were found in 11.6%.

In a clinical trial carried out on 60 women with multiple sclerosis, the researchers obtained data using survey questionnaires. In addition to demographic data, the Multiple Sclerosis Quality of Life-54 (MSQoL-54) instrument was used to determine how multiple sclerosis influences the quality of life of the studied women. Within the frame of this randomized controlled trial, the participants were divided into two equally sized groups (the case and the control group) in which the level of pain and the quality of life were evaluated. The case group exercised pain-managing Yoga methods for three months, keeping the pace of eight 90-minute sessions per month. The control participants were subjected to no intervention. One month after the Yoga therapy, the level of pain and the quality of life were evaluated in both groups and compared to the baseline data. Data were analyzed using SPSS software and paired t-tests. After the Yoga therapy, the case group showed a significant improvement in physical pain management (P=0.007) and the quality of life (P=0.001) as compared to the control group. The results showed that Yoga techniques can alleviate physical pain and improve the quality of life of multiple sclerosis patients.

To assess the effectiveness and safety of uterine packing versus Foley's catheter tamponade for controlling postpartum hemorrhage (PPH) secondary to bleeding tendency after vaginal delivery. This was a prospective observational study conducted on 92 patients with primary PPH due to bleeding tendency following vaginal delivery who were unresponsive to uterotonics and bimanual compression of the uterus. Patients were divided into two groups, Uterine packing group (n = 45) and Foley catheter group (n = 47). The primary outcome was the success rate of the procedure. Secondary outcome addressed the maternal complications. The use of uterine packing resulted in stoppage of active bleeding in 93.3% of cases compared to only 68.1% in the Foley's catheter group (p < 0.05). Although the rate of minor complications namely fever, pain and urinary complaints were higher in the uterine packing group, it does not reach to a significant difference when compared to the Foley's catheter (p > 0.05). Six cases who failed to Foley catheter tamponade underwent emergency hysterectomy with no cases in the uterine packing group. The use of uterine packing to arrest PPH is simple, quick and safe procedure to avoid further surgical interventions and to preserve the fertility in low-resource setting.

To compare the radiographic results (in terms of graft extrusion) and the functional results of lateral meniscus allograft transplantations (MAT) performed with a bony fixation technique or with a soft tissue fixation technique after capsulodesis. A prospective series of 29 consecutive lateral MAT was analyzed. The inclusion criterion for MAT was lateral joint line pain due to a previous meniscectomy. Malalignment, patients who had an Ahlback grade greater than II, and patients with a body mass index over 30 were considered as the exclusion criterion to prevent confounding results. Fifteen of the grafts were fixed with a bony fixation technique (group A). The remaining 14 cases (group B) were fixed with sutures through bone tunnels after lateral capsular fixation (capsulodesis). All patients were studied with magnetic resonance imaging to determine the degree of meniscal extrusion at an average of 18 months of surgery (range, 12-48 months). Meniscal extrusion was measured on coronal magnetic resonance imaging. To standardize the results, the percentage of meniscus extruded for each group was also calculated and compared. The functional results were analyzed by means of standard knee scores (Lysholm, Tegner, and visual analog scale). If we consider the first 4 cases of group B as the learning curve of the new technique, we observe that group A had 8 cases (53.3%) of major extrusion, whereas group B had 1 case (7.1%) (P = .02). When comparing the degree of meniscal extrusion with the type of fixation employed, an even lower percentage of extruded menisci was found in group B (P = .01). The final follow-up Lysholm score in group A was 94.33 ± 5.96 (P < .001) and 91.43 ± 6.19 (P < .001) in group B. The median follow-up Tegner score significantly improved from 4 (range, 2-5) to 7 (range, 6-9) in group A (P < .001) and from 4 (range, 3-5) to 7 (range, 6-8) in group B (P < .001). The average visual analog scale score dropped down 5.87 and 7.29 points in groups A and B, respectively (P < .001). The Knee Injury and Osteoarthritis Outcome Score improved from 51.98 ± 2.84 to 90.88 ± 7.53 in group A (P < .001) and from 50.44 ± 2.32 to 92.01 ± 6.71 in group B (P < .001). Patient satisfaction with regard to the procedure stood at a mean of 3.6 ± 0.2 points out of a maximum of 4 in group A and 3.8 ± 0.4 in group B. There were no complications in this series. The capsulodesis technique in lateral MAT proved not to be statistically different at decreasing the degree of meniscal extrusion with respect to the bone-bridge fixation. If the first 4 cases using the new capsulodesis technique had not included in the results, the capsulodesis technique would have effectively presented better results relative to the degree of meniscal extrusion compared with the bone-bridge fixation technique. In addition, the functional results were similar. Level II, prospective comparative study. Copyright © 2018 Arthroscopy Association of North America. Published by Elsevier Inc. All rights reserved.

The role of dietary factors in the pathophysiology of acne vulgaris is highly controversial. Hence, the aim of this study was to determine the association between dietary factors and acne vulgaris among Malaysian young adults. A case-control study was conducted among 44 acne vulgaris patients and 44 controls aged 18 to 30 years from October 2010 to January 2011. Comprehensive acne severity scale (CASS) was used to determine acne severity. A questionnaire comprising items enquiring into the respondent's family history and dietary patterns was distributed. Subjects were asked to record their food intake on two weekdays and one day on a weekend in a three day food diary. Anthropometric measurements including body weight, height and body fat percentage were taken. Acne severity was assessed by a dermatologist. Cases had a significantly higher dietary glycemic load (175 ± 35) compared to controls (122 ± 28) (p < 0.001). The frequency of milk (p < 0.01) and ice-cream (p < 0.01) consumptions was significantly higher in cases compared to controls. Females in the case group had a higher daily energy intake compared to their counterparts in the control group, 1812 ± 331 and 1590 ± 148 kcal respectively (p < 0.05). No significant difference was found in other nutrient intakes, Body Mass Index, and body fat percentage between case and control groups (p > 0.05). Glycemic load diet and frequencies of milk and ice cream intake were positively associated with acne vulgaris.

Comparative study in patients with infectious diseases admitted to a specialized Internal Medicine-Infectious Diseases Department (IMID) versus those admitted to other medical departments in a university general hospital, investigating quality and cost-effectiveness. Analysis of patients in 10 principle diagnosis-related groups (DRGs) of infectious diseases admitted to the IMID were compared to those admitted to other medical departments (2005-2006). The DRG were divided in 4 main groups: respiratory infections (DGR 88, 89, 90, 540), urinary infections (DRG 320, 321), sepsis (DRG 416, 584), and skin infections (DRG 277, 278). For each group, quality variables (mortality and readmission rate), efficacy variables (mean hospital stay and mean DRG-based cost per patient) and complexity variables (case mix, relative weight, and functional index) were analyzed. 542 patients included in the 10 main infectious disease DRGs were admitted to IMID and 2404 to other medical departments. After adjusting for DRG case mix (case mix 0.99 for IMID and 0.89 for others), mean hospital stay (5.11 days vs. 7.65 days), mortality (3.5% vs. 7.9%) and mean DRG-based economic cost per patient (1521euro/patient vs. 2952euro/patient) was significantly lower in the group of patients hospitalized in IMID than the group in other medical departments (p<0.05). The readmission rate was similar in the 2 groups (5.5% and 6.5%, respectively). The results per each DRG group were similar to the overall results. For a similar case mix, hospitalization in IMID departments had a positive influence on the variables analyzed as compared to hospitalization in other departments, with a shorter mean stay, lower mortality, and lower mean DRG-based economic cost per patient. Creation and development of IMID departments should be an essential objective to improve healthcare quality and respond to social demands.

To verify if patients with polycystic ovarian syndrome (PCOS), have an increased cardiovascular risk compared with healthy controls. Prospective case-control study. University-based practice. Twenty eumenorrheic controls (ten lean [group A] and ten overweight [group B]) and 24 PCOS women (14 lean [group C] and ten overweight [group D]). Cardiovascular risk markers and hormonal parameters were assessed. Androgens, fasting glucose, insulin, leptin, fibrinogen, homocysteine, endothelin-1 and flow-mediated dilatation of the brachial artery were measured to investigate their relationship to weight and to PCOS. The brachial artery diameter and the pulsatility index, after the reactive hyperemia, showed in group A the most intense vasodilatation compared with the other groups. Homocysteine levels did not differ among the groups. Endothelin-1 was significantly higher in group A compared with groups B and D. Leptin was significantly lower in groups A and C compared with groups B and D. Insulin resistance was higher in groups B and D. Group A had significantly higher glucose-insulin ratio compared with all of the other groups; group C had significantly higher glucose-insulin ratio only compared with group D. Weight and PCOS are two independent variables affecting the endothelial function.

Background The aim of this study was to assess the preventive value of active ankle movements in the formation of lower-extremity deep venous thrombosis (DVT), attempting to develop a new method for rehabilitation nursing after orthopedic surgery. Material/Methods We randomly assigned 193 patients undergoing orthopedic surgery in the lower limbs into a case group (n=96) and a control group (n=97). The control group received routine nursing while the case group performed active ankle movements in addition to receiving routine nursing. Maximum venous outflow (MVO), maximum venous capacity (MVC), and blood rheology were measured and the incidence of DVT was recorded. Results On the 11th and 14th days of the experiment, the case group had significantly higher MVO and MVC than the control group (all P<0.05). The whole-blood viscosity at high shear rate and the plasma viscosity were significantly lower in the case group than in the control group on the 14th day (both P<0.05). During the experiment, a significantly higher overall DVT incidence was recorded in the control group (8 with asymptomatic DVT) compared with the case group (1 with asymptomatic DVT) (P=0.034). During follow-up, the case group presented a significantly lower DVT incidence (1 with symptomatic DVT and 4 with asymptomatic DVT) than in the control group (5 with symptomatic DVT and 10 with asymptomatic DVT) (P=0.031). Conclusions Through increasing MVO and MVC and reducing blood rheology, active ankle movements may prevent the formation of lower-extremity DVT after orthopedic surgery. PMID:27600467

Objectives Conventional video-assisted thoracoscopic (VATS) lobectomy for advanced lung cancer is a feasible and safe surgery in experienced centers. The aim of this study is to assess the feasibility of uniportal VATS approach in the treatment of advanced non-small cell lung cancer (NSCLC) and compare the perioperative outcomes and survival with those in early-stage tumors operated through the uniportal approach. Methods From June 2010 to December 2012, we performed 163 uniportal VATS major pulmonary resections. Only NSCLC cases were included in this study (130 cases). Patients were divided into two groups: (A) early stage and (B) advanced cases (>5 cm, T3 or T4, or tumors requiring neoadjuvant treatment). A descriptive and retrospective study was performed, comparing perioperative outcomes and survival obtained in both groups. A survival analysis was performed with Kaplan-Meier curves and the log-rank test was used to compare survival between patients with early and advanced stages. Results A total of 130 cases were included in the study: 87 (A) vs. 43 (B) patients (conversion rate 1.1 vs. 6.5%, P=0.119). Mean global age was 64.9 years and 73.8% were men. The patient demographic data was similar in both groups. Upper lobectomies (A, 52 vs. B, 21 patients) and anatomic segmentectomies (A, 4 vs. B, 0) were more frequent in group A while pneumonectomy was more frequent in B (A, 1 vs. B, 6 patients). Surgical time was longer (144.9±41.3 vs. 183.2±48.9, P<0.001), and median number of lymph nodes (14 vs. 16, P=0.004) were statistically higher in advanced cases. Median number of nodal stations (5 vs. 5, P=0.165), days of chest tube (2 vs. 2, P=0.098), HOS (3 vs. 3, P=0.072), and rate of complications (17.2% vs. 14%, P=0.075) were similar in both groups. One patient died on the 58th postoperative day. The 30-month survival rate was 90% for the early stage group and 74% for advanced cases Conclusions Uniportal VATS lobectomy for advanced cases of NSCLC is a safe and reliable procedure that provides perioperative outcomes similar to those obtained in early stage tumours operated through this same technique. Further long term survival analyses are ongoing on a large number of patients. PMID:24976985

To assess the clinical outcomes and costs associated with robotic single-site (RSS) surgery compared with those of conventional laparoscopy (CL) in gynecology. Retrospective case-control study (Canadian Task Force classification II-2). University-affiliated community hospital. Female patients undergoing RSS or CL gynecologic procedures. Comparison of consecutive RSS gynecologic procedures (cases) undertaken between October 2013 and March 2014 with matched CL procedures (controls) completed during the same time period by the same surgeon. Patient demographic data, operative data, and hospital financial data were abstracted from the electronic charts and financial systems. An incremental cost analysis based on the use of disposable equipment was performed. Total hospital charges were determined for matched RSS cases vs CL cases. RSS surgery was completed in 25 out of 33 attempts; 3 cases were aborted before docking, and 5 were converted to a multisite surgery. There were no intraoperative complications or conversions to laparotomy. The completed cases included 11 adnexal cases and 14 hysterectomies, 3 of which included pelvic lymph node dissection. Compared with the CL group, total operative times were higher in the RSS group; however, there were no significant between-group differences in estimated blood loss, length of hospital stay, or complication rates. Disposable equipment cost per case, direct costs, and total hospital charges were evaluated. RSS was associated with an increased disposable cost per case of $248 to $378, depending on the method used for vaginal cuff closure. The average total hospital charges for matched outpatient adnexal surgery were $15,450 for the CL controls and $18,585 for the RSS cases (p < .001), and the average total hospital charges for matched outpatient benign hysterectomy were $14,623 for the CL controls and $21,412 for the RSS cases (p < .001). Although RSS surgery and CL have comparable clinical outcomes in selected patients, RSS surgery remains associated with increased incremental disposable cost per case and total hospital charges. Careful case selection and judicious use of equipment are necessary to maximize cost-effectiveness in RSS gynecologic surgery. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

The aim of the study was to determine the quality of basic life support (BLS) in out-of-hospital cardiac arrests (OHCAs) receiving bystander cardiopulmonary resuscitation (CPR) and public automated external defibrillator (AED) application. From January 2006 to December 2012, data were prospectively collected from OHCA) and impending cardiac arrests treated with and without public AED before emergency medical technician (EMT) arrival. Basic life support actions and outcomes were compared between cases with and without public AED application. Interruptions of CPR were compared between 2 groups of AED users: health care provider (HCP) and non-HCP. Public AEDs were applied in 10 and 273 cases of impending cardiac arrest and non-EMT-witnessed OHCAs, respectively (4.3% of 6407 non-EMT-witnessed OHCAs). Defibrillation was delivered to 33 (13.3%) cases. Public AED application significantly improved the rate of 1-year neurologically favorable survival in bystander CPR-performed cases with shockable initial rhythm but not in those with nonshockable rhythm. Emergency calls were significantly delayed compared with other OHCAs without public AED application (median: 3 and 2 minutes, respectively; P < .0001). Analysis of AED records obtained from 136 (54.6%) of the 249 cases with AED application revealed significantly lower rate of compressions delivered per minute and significantly greater proportion of CPR pause in the non-HCP group. Time interval between power on and the first electrocardiographic analysis widely varied in both groups and was significantly prolonged in the non-HCP group (P = .0137). Improper BLS responses were common in OHCAs treated with public AEDs. Periodic training for proper BLS is necessary for both HCPs and non-HCPs. Copyright © 2014 Elsevier Inc. All rights reserved.

To shed light on attitudes towards loyalty conflicts among general practitioners (GPs) compared with related specialists such as gynaecologists and paediatricians. A postal questionnaire containing three case histories with arguments for and against different ways of acting in loyalty conflicts. The medical problems of the clinical cases varied, but the ethical ones were in principle similar. A random sample of all Swedish GPs, gynaecologists, and paediatricians. GPs (n = 313), paediatricians (n = 197), and gynaecologists (n = 236). On average 71% of the doctors replied. The gynaecologists differed from the other groups by being markedly loyal to the individual patient especially in one case. The paediatricians tended to reply most consistently and they seemed to favour the family perspective, compared with the other doctors. The GPs' response pattern fell in between the other two groups. The study indicates that ethical reasoning depends on the doctors' different medical background with regard to specialty. This study should be followed by others in order to give further explanation of the findings.

Introduction: To analyze the pattern of brain metastasis (BM), and to use intensity modulated radiation therapy (IMRT) for target dose escalation in cases with ≤3 metastatic lesions (oligometastases). Materials and Methods: Thirty-two consecutive cases of BM treated during September 2009 to August 2012 were analyzed retrospectively. Results: The study comprised 13 males (40.62%) and 19 females (59.37%). Thirteen (40%) patients presented with disseminated intracranial metastases, while 19 (60%) had ≤3 foci. In 25 cases (78%), the primary was located either in the breast (14 cases) or lung (11 cases). The 13 patients with disseminated intracranial metastases received whole brain radiation therapy to a dose of 30 Gy/10-12 daily fractions (Group A) while the 19 cases with ≤3 lesions received an additional dose of 6-10 Gy to gross lesions using a simultaneous integrated boost (SIB) with IMRT thus receiving a total dose of 36-40 Gy/12-15 fractions (Group B). Overall survival (OS) for the breast primary was 6.3 and lung primary was 5.3 months, respectively. The mean OS for breast cases in Group B was higher (9.5 months) as compared to Group A cases (1.9 months) and was statistically significant (P = 0.0056). Similarly, primary lung cancer cases in Group B showed a mean OS of 8.75 months versus 2.6 months for Group A cases (P = 0.213). Conclusions: IMRT is a safe and effective technique in cases with oligometastases for dose escalation in the form of SIB. PMID:25839012

Along with the proliferation of Open Access (OA) publishing, the interest for comparing the scientific quality of studies published in OA journals versus subscription journals has also increased. With our study we aimed to compare the methodological quality and the quality of reporting of primary epidemiological studies and systematic reviews and meta-analyses published in OA and non-OA journals. In order to identify the studies to appraise, we listed all OA and non-OA journals which published in 2013 at least one primary epidemiologic study (case-control or cohort study design), and at least one systematic review or meta-analysis in the field of oncology. For the appraisal, we picked up the first studies published in 2013 with case-control or cohort study design from OA journals (Group A; n = 12), and in the same time period from non-OA journals (Group B; n = 26); the first systematic reviews and meta-analyses published in 2013 from OA journals (Group C; n = 15), and in the same time period from non-OA journals (Group D; n = 32). We evaluated the methodological quality of studies by assessing the compliance of case-control and cohort studies to Newcastle and Ottawa Scale (NOS) scale, and the compliance of systematic reviews and meta-analyses to Assessment of Multiple Systematic Reviews (AMSTAR) scale. The quality of reporting was assessed considering the adherence of case-control and cohort studies to STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) checklist, and the adherence of systematic reviews and meta-analyses to Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) checklist. Among case-control and cohort studies published in OA and non-OA journals, we did not observe significant differences in the median value of NOS score (Group A: 7 (IQR 7-8) versus Group B: 8 (7-9); p = 0.5) and in the adherence to STROBE checklist (Group A, 75% versus Group B, 80%; p = 0.1). The results did not change after adjustment for impact factor. The compliance with AMSTAR and adherence to PRISMA checklist were comparable between systematic reviews and meta-analyses published in OA and non-OA journals (Group C, 46.0% versus Group D, 55.0%; p = 0.06), (Group C, 72.0% versus Group D, 76.0%; p = 0.1), respectively). The epidemiological studies published in OA journals in the field of oncology approach the same methodological quality and quality of reporting as studies published in non-OA journals.

To explore the clinicopathological characteristics of hereditary ovarian cancer syndrome (HOCS). From Jan. 2000 to Jan. 2007, among 580 cases of primary ovarian cancer, 42 cases (hereditary group), who had a positive family history of ovarian cancer and met the diagnostic criteria of HOCS, were analyzed retrospectively. One hundred cases without a family history of ovarian cancer were enrolled randomizely as control group (sporadic group). The incidence of HOCS was 7.2% (42/580). Forty-two cases associated tumors affected at least 2 successive generations in 31 families and affected 1 generation in 8 families. Eighty-seven percent (27/31) was from maternal lineage, while 13% (4/31) from paternal lineage. Earlier age of onset was significantly difference between two groups [(49 +/- 10) years vs. (55 +/- 10) years, P < 0.05]. There were 90% belong to serous adenocarcinoma in the hereditary group, while 84% in the sporadic group. There was statistical difference in the proportion of mucinous adenocarcinoma (0 vs. 11%, P < 0.05). The most common clinical manifestations were abdominal distention and anorexia (64% vs. 70%, P > 0.05), International Federational of Gynecology Obstetrics (FIGO) stage III (62% vs. 63%, P > 0.05) between two groups. Fourteen cases (33%,14/42) were previously untreated in the hereditary group, while 40 cases (40%, 40/100) in the sporadic group. There were 15 cases (36%, 15/42) underwent secondary surgery and 15 cases (36%, 15/42) underwent third surgery or more in hereditary group, while 50 cases (50%,50/100) and 27 cases (27%, 27/100) in the sporadic group. The mean number of chemotherapy cycles received in two groups was 13.3 and 11.8 (P > 0.05). The 3-year and 5-year survival rate in hereditary group were 73.6% and 54.9% respectively, compared with 47.4% and 21.2% (P < 0.05) in sporadic group. Hereditary ovarian cancer mostly from maternal lineage are featuring in early age of onset, serous adenocarcinoma, advanced stage (stage III), and better prognosis after the comprehensive treated by cytoreductive surgery plus with chemotherapy.

This study is a phase 1 and 2 clinical trial for investigating the safety profile, effective treatment dose and effectiveness of the newly developed thermosensitive hydrogel-type cultured epidermal allograft. For phase 1, the keratinocytes were divided into 3 groups as follows, with 5 patients in each group: (1) low-dose group (6.7×10(6)/1.5mL), (2) medium-dose group (2×10(7)/1.5mL), and (3) high-dose group (6.0×10(7)/1.5mL). The second phase of the trial proceeded with 10 cases after choosing the most effective dose based on the analysis of the first phase. When comparing re-epithelialization time, medium- and high-dose group showed significantly shorter re-epithelialization time than low-dose group (p=0.003 and p=0.002). A total of 15 cases, 5 cases selected from phase 1 and 10 cases test in phase 2 with the medium dose, were compared with the re-epithelialization period. The re-epithelialization period was 9.6±4.0 days in the test site and 12.4±4.8 days in the control site. In the test site, re-epithelialization was 2.8±1.8 days faster than in the control site (p<0.0001). There was no significant adverse reaction in our clinical trial. In conclusion, this new type of CEAllo accelerates wound healing time and shows the safety. Copyright © 2014 Elsevier Ltd and ISBI. All rights reserved.

To investigate the role of anti-human heat shock protein 60 (hHsp60) antibody positivity in the pathogenesis of ectopic pregnancy, following Chlamydia trachomatis (CT) infection. In a case-control study, serological tests for anti-hHsp60 were performed in ectopic pregnancies (study group) and parturients with normal reproductive histories (control group). All participants in both groups were CT IgG(+). hHsp60 IgG(+) prevalences were compared between the two groups, by semiquantitative ELISA. Data were evaluated using nonparametric and parametric tests and multivariable regression. After an initial pilot study, two groups were formed: 63 ectopic gestations (study group) and 95 normal parturients (control group), all CT IgG(+). Blood samples from all cases were tested for anti-hHsp60 IgG. Age, gravidity, and practising contraception were higher in the control group, while a history of pelvic infections were more common in the study group. Hsp60 IgG(+) was found to be significantly higher in the control group (63/95, 66.3%) compared to study group (30/63, 47.6%). Regression analysis revealed anti-hHsp60 positivity was an independent factor delineating the two groups. Immunity to hHsp60 is less common in CT IgG(+) ectopic pregnancies than CT IgG(+) fertile subjects without a history of ectopic pregnancies. Hence, our findings suggest that hHsp60 seropositivity may decrease the probability of an ectopic gestation in subjects with previous CT infections. Copyright © 2018 Elsevier B.V.

To evaluate the use of ear endoscopy in the postoperative management of open mastoidectomy cavities, and to test whether ear endoscopy improves inspection and cleaning compared with ear microscopy. Prospective study. Thirty-two ears were divided into two groups: group 1, examination and cleaning of mastoid cavities under endoscopic visualization after microscopic standard ear cleaning; group 2, examination and cleaning of mastoid cavities under microscopic visualization after endoscope-assisted ear cleaning. We assessed the ability of each method to provide exposure and facilitate cleaning, comparing the benefits of microscopy and endoscopy when used sequentially and vice-versa. Endoscopy provided additional benefits for exposure in 61.1% of cases and cleaning in 66.7%. Microscopy provided no additional benefits in terms of exposure in any case, and provided added benefit for cleaning in only 21.4% of cases. For outpatient postoperative care of open mastoidectomy cavities, ear endoscopy provides greater benefit over ear microscopy than vice-versa. In over half of all cases, endoscopy was able to expose areas not visualized under the microscope. Furthermore, in two-thirds of cases, endoscopy enabled removal of material that could not be cleared under microscopy. Ear endoscopy was superior to microscopy in terms of enabling exposure and cleaning of hard-to-reach sites, due to its wider field of vision. Ear endoscopy is a feasible technique for the postoperative management of open mastoidectomy cavities. Ear endoscopy provided superior advantages in terms of exposure and aural cleaning compared with microscopy.

OBJECTIVE: The features of earthquake-related head injuries may be different from those of injuries obtained in daily life because of differences in circumstances. We aim to compare the features of head traumas caused by the Sichuan earthquake with those of other common head traumas using multidetector computed tomography. METHODS: In total, 221 patients with earthquake-related head traumas (the earthquake group) and 221 patients with other common head traumas (the non-earthquake group) were enrolled in our study, and their computed tomographic findings were compared. We focused the differences between fractures and intracranial injuries and the relationships between extracranial and intracranial injuries. RESULTS: More earthquake-related cases had only extracranial soft tissue injuries (50.7% vs. 26.2%, RR = 1.9), and fewer cases had intracranial injuries (17.2% vs. 50.7%, RR = 0.3) compared with the non-earthquake group. For patients with fractures and intracranial injuries, there were fewer cases with craniocerebral injuries in the earthquake group (60.6% vs. 77.9%, RR = 0.8), and the earthquake-injured patients had fewer fractures and intracranial injuries overall (1.5±0.9 vs. 2.5±1.8; 1.3±0.5 vs. 2.1±1.1). Compared with the non-earthquake group, the incidences of soft tissue injuries and cranial fractures combined with intracranial injuries in the earthquake group were significantly lower (9.8% vs. 43.7%, RR = 0.2; 35.1% vs. 82.2%, RR = 0.4). CONCLUSION: As depicted with computed tomography, the severity of earthquake-related head traumas in survivors was milder, and isolated extracranial injuries were more common in earthquake-related head traumas than in non-earthquake-related injuries, which may have been the result of different injury causes, mechanisms and settings.

The relationship between whiplash trauma and chronic orofacial pain is unclear, especially with regard to the time elapsed from trauma to development of orofacial pain. The aim was to analyze prevalence of jaw pain and disability, as well as the relationship between pain and disability in the jaw and neck regions in the early nonchronic stage after whiplash trauma. In this case-control study, 70 individuals (40 women, 30 men, mean age 35.5 y) who visited an emergency department with neck pain following a car accident were examined within 3 wk of trauma (group 1) and compared with 70 individuals (42 women, 28 men, mean age 33.8 y), who declined to attend a clinical examination but agreed to fill in questionnaires (group 2). The 2 case groups were compared with a matched control group of 70 individuals (42 women, 28 men, mean age 37.6 y) without a history of neck trauma. All participants completed questionnaires regarding jaw pain and dysfunction, rating pain intensity in jaw and neck regions on the Numerical Rating Scale, the Neck Disability Index, and Jaw Disability Checklist. Compared with controls, individuals with a recent whiplash trauma reported more jaw pain and dysfunction. Furthermore, there was a moderate positive correlation between jaw and neck pain ratings for group 1 (r = 0.61, P < 0.0001) and group 2 (r = 0.59, P < 0.0001). In the logistic regression analysis, cases showed higher odds ratios (range, 6.1 to 40.8) for jaw and neck pain and disability compared with controls. Taken together, the results show that individuals with a recent whiplash trauma report more jaw pain and disability compared with controls without a history of neck trauma. Furthermore, the correlation between jaw and neck pain intensity implies that intensity of neck pain in the acute stage after whiplash trauma might be a possible risk factor also for development of chronic orofacial pain. © International & American Associations for Dental Research 2016.

We reanalyzed data from a previous randomized crossover design that administered high or low doses of intravenous immunoglobulin (IgG) to 12 patients with hypogammaglobulinaemia over 12 time points, with crossover after time 6. The objective was to see if results corresponded when analyzed as a set of single-case experimental designs vs. as a usual randomized controlled trial (RCT). Two blinded statisticians independently analyzed results. One analyzed the RCT comparing mean outcomes of group A (high dose IgG) to group B (low dose IgG) at the usual trial end point (time 6 in this case). The other analyzed all 12 time points for the group B patients as six single-case experimental designs analyzed together in a Bayesian nonlinear framework. In the randomized trial, group A [M = 794.93; standard deviation (SD) = 90.48] had significantly higher serum IgG levels at time six than group B (M = 283.89; SD = 71.10) (t = 10.88; df = 10; P < 0.001), yielding a mean difference of MD = 511.05 [standard error (SE) = 46.98]. For the single-case experimental designs, the effect from an intrinsically nonlinear regression was also significant and comparable in size with overlapping confidence intervals: MD = 495.00, SE = 54.41, and t = 495.00/54.41 = 9.10. Subsequent exploratory analyses indicated that how trend was modeled made a difference to these conclusions. The results of single-case experimental designs accurately approximated results from an RCT, although more work is needed to understand the conditions under which this holds.

In Ireland, pregnant women are not routinely screened for subclinical hypothyroidism (SCH). Our objective was to compare the intelligence quotient (IQ) of children whose mothers had been diagnosed with SCH prenatally with matched controls using a case-control retrospective study. In a previous study from our group, 1000 healthy nulliparous women were screened anonymously for SCH. This was a laboratory diagnosis involving elevated TSH with normal fT4 or normal TSH with hypothyroxinaemia. We identified 23 cases who agreed to participate. These were matched with 47 controls. All children underwent neurodevelopmental assessment at age 7-8. Wechsler Intelligence Scale for Children IV assessment scores were used to compare the groups. Our main outcome measure was to identify whether there was a difference in IQ between the groups. From the cohort of cases, 23 mothers agreed to the assessment of their children as well as 47 controls. The children in the control group had higher mean scores than those in the case group across Verbal Comprehension Intelligence, Perceptual Reasoning Intelligence, Working Memory Intelligence, Processing Speed Intelligence and Full Scale IQ. Mann-Whitney U-test confirmed a significant difference in IQ between the cases (composite score 103.87) and the controls (composite score 109.11) with a 95% confidence interval (0.144, 10.330). Our results highlight significant differences in IQ of children of mothers who had unrecognised SCH during pregnancy. While our study size and design prevents us from making statements on causation, our data suggest significant potential public health implications for routine prenatal screening. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

This study aimed to compare the learning curves and early postoperative outcomes for conventional laparoscopic (CL) and single incision laparoscopic (SIL) right hemicolectomy (RHC). This retrospective study included the initial 35 cases in each group. Learning curves were evaluated by the moving average of operative time, mean operative time of every five consecutive cases, and cumulative sum (CUSUM) analysis. The learning phase was considered overcome when the moving average of operative times reached a plateau, and when the mean operative time of every five consecutive cases reached a low point and subsequently did not vary by more than 30 minutes. Six patients with missing data in the CL RHC group were excluded from the analyses. According to the mean operative time of every five consecutive cases, learning phase of SIL and CL RHC was completed between 26 and 30 cases, and 16 and 20 cases, respectively. Moving average analysis revealed that approximately 31 (SIL) and 25 (CL) cases were needed to complete the learning phase, respectively. CUSUM analysis demonstrated that 10 (SIL) and two (CL) cases were required to reach a steady state of complication-free performance, respectively. Postoperative complications rate was higher in SIL than in CL group, but the difference was not statistically significant (17.1% vs. 3.4%). The learning phase of SIL RHC is longer than that of CL RHC. Early oncological outcomes of both techniques were comparable. However, SIL RHC had a statistically insignificant higher complication rate than CL RHC during the learning phase.

Risk factors for invasive epithelial ovarian cancer (IEOC) among Hispanics and African Americans are understudied despite notable differences in incidence relative to non-Hispanic whites. We used multivariate logistic regression to examine parity, oral contraceptive use, tubal ligation, endometriosis, family history of ovarian cancer, and talc use and risk of IEOC among Hispanics (308 cases and 380 controls), African Americans (128 cases and 143 controls), and non-Hispanic whites (1,265 cases and 1,868 controls) using four case-control studies we conducted in Los Angeles County. We expressed each of these factors in the form of increasing risk and calculated population attributable risk percentage (PAR%) estimates for the six risk factors separately and jointly in the three groups. The risk associations with these six well-accepted factors were comparable in the three groups. The significant racial/ethnic differences in the prevalence of these factors and differences in their oophorectomy rates explained 31% of the lower incidence in African Americans compared with non-Hispanic whites, but only 13% of the lower incidence in Hispanics. The PAR%s ranged from 27.5% to 31.0% for no tubal ligation, 15.9% to 22.2% for not using oral contraceptives, and 12.2% to 15.1% for using talc in the three groups. All six risk factors are comparably important in the three groups. Differences in the prevalence of these factors and their oophorectomy rates explained approximately one third of the difference in incidence between African Americans and non-Hispanic whites. Devising strategies to lessen the burden of IEOC will be applicable to all three racial/ethnic groups. ©2015 American Association for Cancer Research.

Agriculture has undergone major changes, and farmers have been found to have a high prevalence of depression symptoms. We investigated the risk of work disability in Norwegian farmers compared with other occupational groups, as well as the associations between symptoms of anxiety and depression and future disability pension. We linked working participants of the HUNT2 Survey (1995-97) aged 20-61.9 years, of whom 3495 were farmers and 25,521 had other occupations, to national registry data on disability pension, with follow-up until 31 December 2010. We used Cox proportional hazards regression to estimate hazard ratios (HRs) of disability pension, and to investigate the associations between symptoms of anxiety and depression caseness at baseline (score on the anxiety or depression subscales of the Hospital Anxiety and Depression Scale (HADS) ≥8) and disability pension. Farmers had a twofold increased risk of disability pension (age-adjusted and sex-adjusted HR 2.07, 95% CI 1.80 to 2.38) compared with higher grade professionals. Farmers with symptoms of depression caseness had a 53% increased risk of disability pension (HR 1.53, 95% CI 1.25 to 1.87) compared with farmers below the cut-off point of depression caseness symptoms, whereas farmers with symptoms of anxiety caseness had a 51% increased risk (HR 1.51, 95% CI 1.23 to 1.86). Farmers have an increased risk of disability pension compared with higher grade professionals, but the risk is lower than in most other manual occupational groups. Farmers who report high levels of depression or anxiety symptoms are at substantially increased risk of future work disability, and the risk increase appears to be fairly similar across most occupational groups.

2013-01-01

Background and aims The fast development of e-learning and social forums demands us to update our understanding of e-learning and peer learning. We aimed to investigate if higher, pre-defined levels of e-learning or social interaction in web forums improved students’ learning ability. Methods One hundred and twenty Danish medical students were randomized to six groups all with 20 students (eCases level 1, eCases level 2, eCases level 2+, eTextbook level 1, eTextbook level 2, and eTextbook level 2+). All students participated in a pre-test, Group 1 participated in an interactive case-based e-learning program, while Group 2 was presented with textbook material electronically. The 2+ groups were able to discuss the material between themselves in a web forum. The subject was head injury and associated treatment and observation guidelines in the emergency room. Following the e-learning, all students completed a post-test. Pre- and post-tests both consisted of 25 questions randomly chosen from a pool of 50 different questions. Results All students concluded the study with comparable pre-test results. Students at Level 2 (in both groups) improved statistically significant compared to students at level 1 (p>0.05). There was no statistically significant difference between level 2 and level 2+. However, level 2+ was associated with statistically significant greater student's satisfaction than the rest of the students (p>0.05). Conclusions This study applies a new way of comparing different types of e-learning using a pre-defined level division and the possibility of peer learning. Our findings show that higher levels of e-learning does in fact provide better results when compared with the same type of e-learning at lower levels. While social interaction in web forums increase student satisfaction, learning ability does not seem to change. Both findings are relevant when designing new e-learning materials. PMID:24229729

Competency in end-of-life (EOL) care is a growing expectation for health professions students. This study assessed the impact of four EOL care scenarios, using high-fidelity simulation, on the perceived learning needs and attitudes of pharmacy and nursing students. On three campuses, pharmacy students (N = 158) were exposed to standard paper EOL case scenarios, while a fourth campus exposed eight graduate nursing and 37 graduate pharmacy students to simulated versions of the same cases. The paper-based groups produced similar pre-post changes on the End of Life Professional Caregiver Survey. Results were pooled and compared with the simulation-only group, revealing significantly higher changes in pre-post scores for the simulation group. Students participating in the simulation group showed some significant differences in attitudes toward EOL care, compared with students in the classroom setting. [J Nurs Educ. 2017;56(4):205-210.].

To evaluate and compare the effectiveness of double Endobutton technique and suture anchor combined Endobutton plate in the treatment of Tossy type III acromioclavicular joint dislocation. Between May 2010 and March 2014, a retrospective study was preformed on 56 patients with Tossy type III acromioclavicular joint dislocation. The coracoclavicular ligament was reconstructed with double Endobutton technique in 31 cases (Endobutton group), and with suture anchor combined Endobutton plate in 25 cases (Anchor group). There was no significant difference in age, gender, injury causes, injury side, associated injury, medical comorbidities, and disease duration between 2 groups (P>0.05). The operation time, medical device expenses, postoperative complications, preoperative and postoperative Constant-Murley scores, and postoperative Karlsson grading of the injured shoulder were compared between 2 groups. The average operation time in Endobutton group was significantly greater than that in Anchor group (t = 4.285, P = 0.000); there was no significant difference in the medical device expenses between 2 groups (t = 1.555, P = 0.126). Primary healing of incision was obtained in all patients of 2 groups; no early complications of infection and skin necrosis occurred. All patients were followed up 15.6 months on average (range, 11-35 months). During follow-up, some loss of reduction and ectopic ossification in the coracoclavicular gap were observed in 1 case and 6 cases of Endobutton group, respectively. No recurrence of acromioclavicular joint dislocation, implant fixation loosening and broken, and secondary fractures occurred in the other patients. There was significant difference in the incidence of postoperative complications between 2 groups (P = 0.013). Constant-Murley scores of the injured shoulder significantly increased at 9 months after operation when compared with preoperative values in 2 groups (P < 0.05), but no significant difference was observed between 2 groups (P > 0.05). At last follow-up, there was no significant difference in Karlsson grading between 2 groups (Z = -0.628, P = 0.530). Both double Endobutton technique and suture anchor combined Endobutton plate have good effectiveness in the treatment of Tossy type III acromioclavicular joint dislocation. But the latter is associated with easier operation, less operation time, and less complications.

Abortion, spontaneous or induced, is a common complication of pregnancy and exploration of available and safe regimens for medical abortion in developing countries seems crucial. The present study was aimed to assess the effect of letrozole in combination with misoprostol in women eligible for legal therapeutic abortion with gestational age ≤14weeks. This clinical randomized trial was conducted on 78 women who were candidate of medical abortion and eligible for legal abortion with gestational age ≤14 weeks that were randomly divided into two groups of case and controls. Case group received daily oral dose of 10mg letrozole for three days followed by vaginal misoprostol. In control group the patients received only vaginal misoprostol. The rate of complete abortion, induction-of-abortion time, and side-effects were assessed. Complete abortion was observed in 30 patients (76.9%) in case group and 9 (23.1%) cases were failed. In control group there was 16 (41.03%) complete abortions and 23 (58.97%) cases were failed to abort. Patients with gestational age of between 6 and 10 weeks did not show significant difference in both groups (P=0.134). Regarding pregnancy remnants there were significant differences between two groups (P=0.034). The time form admission to discharge in case groups were significantly shorter than those in control group (P=0.001). The indication for curettage in case group was significantly less than control group (P=0.001). A 3-day course of letrozole (10mg/daily) followed by misoprostol was associated with a higher complete abortion and lower curettage rates and reduction in time from admission to discharge in women with gestational age ≤14 weeks compared to misoprostol alone.

Although human patient simulators provide an innovative teaching method for nursing students, they are quite expensive. To investigate the value of this expenditure, a quantitative, quasi-experimental, two-group pretest and posttest design was used to compare two educational interventions: human patient simulators and interactive case studies. The sample (N = 49) consisted of students from baccalaureate, accelerated baccalaureate, and diploma nursing programs. Custom-designed Health Education Systems, Inc examinations were used to measure knowledge before and after the implementation of the two educational interventions. Students in the human patient simulation group scored significantly higher than did those in the interactive case study group on the posttest Health Education Systems, Inc examination, and no significant difference was found in student scores among the three types of nursing programs that participated in the study. Data obtained from a questionnaire administered to participants indicated that students responded favorably to the use of human patient simulators as a teaching method.

Hypothyroidism is associated with significant neurocognitive deficits because hypothyroidism prevents the brain from adequately sustaining the energy consuming processes needed for neurotransmission, memory, and other higher brain functions. Hence, the study was done to assess the cognitive functions of newly diagnosed subclinical and clinical hypothyroid patients by evoked response potential P300. 75 patients each of newly diagnosed subclinical and clinical hypothyroid patients attending endocrinology clinic and 75 healthy age and sex matched euthyroid controls were considered for the study. P300 was recorded with Record Medicare System Polyrite, Chandigarh using auditory "oddball paradigm". The data was analyzed using ANOVA followed by post Tukey's test. Newly diagnosed clinical hypothyroid patients showed a significant increase in P300 latency compared to control (P < 0.05) and subclinical cases (P < 0.01) while there was no significant difference between the P300 latency of subclinical cases and control group. Also, there was no significant difference in P300 amplitude among the three groups. P300 latency in case of newly diagnosed hypothyroid clinical cases is significantly increased compared to newly diagnosed subclinical cases and control.

Among children conceived by assisted reproductive technology (ART), increased risk of adverse birth outcomes has been observed, including multiple births, preterm births, and congenital malformations. Regarding cancer among ART-conceived children, findings are discrepant. This is a historical cohort of 9,042 ART-conceived children and 211,763 spontaneously conceived (SC) children born from 1997 through 2004. The median duration of follow-up was 10.6 years (interquartile range 9.0-12.3) in the ART group and 9.3 years (interquartile range 8.0-10.6) in the SC group. The cohort database was linked with the Israel National Cancer Registry updated until December 31, 2011 using each child's personal identification number. Twenty-one cases of cancer were identified in the ART group (2.2 per 10,000 person-years), as compared to 361 cancer cases in the SC group (1.8 per 10,000 person-years). The relative risk (RR) for overall cancer in the ART group compared to the SC group adjusted for maternal characteristics was 1.18 (95% confidence interval [CI] 0.80-1.75). ART children had a significantly increased risk for specific cancers, although based on small number of cases, including two cases of retinoblastoma (RR 6.18, 95% CI 1.22-31.2), as well as four cases of renal tumors (RR 3.25, 95% CI 1.67-6.32). A statistically significant increased risk for two pediatric cancers was found. However, for overall types of cancer the risk estimate was elevated but not statistically significant. Further studies with larger sample size and longer follow-up time are warranted in order to either confirm or refute these findings. © 2016 Wiley Periodicals, Inc.

Various drugs have been tried to hasten cervical dilatation so that problems and hazards of prolonged labour both for the mother and fetus are minimised without increasing maternal or perinatal mortality and morbidity. To compare the effect of camylofin dihydrochloride with combination of valethemate bromide (epidosin) & hyoscine N butyl bromide (buscopan) on cervical dilatation, evaluate the incidence of side effects and to look for neonatal outcome. Two hundred cases were included of primigravidae or multigravidae with gestational age of 37 to 40 weeks with full term with single foetus,vertex presentation and no major antenatal complication of women in labour, admitted to labour room of gynaecology Department, Government Medical College, Patiala, India, was studied and divided into 2 groups Group A-100 Cases - labour accelerated by camylofin dihydro chloride and Group B-100 Cases-labour accelerated by valethemate bromide (epidosin) and hyoscine N butyl bromide. The mean age, parity and period of gestation in Anafortan group was 24.13 ± 3.60 years, 49% primigravidae and 51% multigravidae and 38.81 ± 1.09 weeks, while that in Epidosin + Buscopan group was 24.43 ± 3.42 years, 45% primigravidae and 51% multigravidae and 38.94 ± 1.09 weeks respectively. The difference was insignificant and both the groups were comparable. Mean duration of Active phase of 1st stage of labor was 141.40 ± 55.41 minutes in Anafortan group and 181.46 ± 75.58 minutes in Epidosin + Buscopan group. Mean rate of cervical dilatation according to active phase of first stage was 3.33 ± 1.03 cm/hours in Anafortan group and 2.69 ± 1.03 cm/hr in Epidosin + Buscopan group. The difference between the two groups is highly significant (p < 0.01) thus it is concluded that Anafortan hastened the rate of cervical dilatation.

Background: It is still a challenge for the cardiac surgeons to achieve adequate revascularization for diffused coronary artery disease (CAD). Coronary endarterectomy (CE) offers an alternative choice of coronary artery reconstruction and revascularization. In this study, short-term result of CE combined with coronary artery bypass graft (CABG) was discussed in the treatment for the diffused CAD. Methods: From January 2012 to April 2014, 221 cases of CABG were performed by the same surgeon in our unit. Among these cases, 38 cases of CE + CABG were performed, which was about 17.2% (38/221) of the cohort. All these patients were divided into two groups: CE + CABG group (Group A) and CABG alone group (Group B). All clinical data were compared between the two groups, and postoperative complications and in-hospital mortality were analyzed. The categorical and continuous variables were analyzed by Chi-square test and Student's t-test respectively. Results: Diabetes mellitus, hypertension, hyperlipidemia, and peripheral vascular disease were more common in group A. In this cohort, a total of 50 vessels were endarterectomized. Among them, CE was performed on left anterior descending artery in 11 cases, on right coronary artery in 29 cases, on diagonal artery in 3 cases, on intermediate artery in 2 cases, on obtuse marginal artery in 5 cases. There was no hospital mortality in both groups. The intro-aortic balloon pump was required in 3 cases in Group A (3/38), which was more often than that in Group B (3/183). At the time of follow-up, coronary computed tomography angiogram showed all the grafts with CE were patent (50/50). There is no cardio-related mortality in both groups. All these patients were free from coronary re-intervention. Conclusions: Coronary endarterectomy + CABG can offer satisfactory result for patients with diffused CAD in a short-term after the operation. PMID:26021501

We evaluated the usefulness of pulmonary surfactant protein A (SP-A) as a practical diagnostic marker of fatal mechanical asphyxia in forensic autopsy cases. A total of 27 cases of asphyxia were examined histologically and immunohistochemically and compared with a control group consisting of 16 cases of poisoning (n = 9) and peracute death (n = 7). Both groups showed histological findings of local atelectasis and local emphysema, congestion, intra-alveolar and interstitial edema in most cases and pulmonary hemorrhages in some cases. The mechanical asphyxia group showed a significantly increased intensity of SP-A staining in the intra-alveolar space accompanied by many massive aggregates in approximately 60% of cases, which was not found in the control group. These structures may be interpreted as aggregates of pulmonary surfactant released from the alveolar wall due to enhanced secretion caused by strong forced breathing or over-excitement of the autonomic nervous system by mechanical asphyxia. The results of our investigation suggest the practical usefulness of the immunohistochemical detection of SP-A in distinguishing mechanical asphyxia from other types of hypoxia.

Young adults with Type 2 diabetes have higher physical morbidity and mortality than other diabetes sub-groups, but differences in psychosocial outcomes have not yet been investigated. We sought to compare depression and anxiety symptoms and self-care behaviours of young adults with Type 2 diabetes with two matched control groups. Using cross-sectional survey data from the Australian and Dutch Diabetes Management and Impact for Long-term Empowerment and Success (MILES) studies, we matched 93 young adults (aged 18-39 years) with Type 2 diabetes (case group) with: (i) 93 older adults ( ≥ 40 years) with Type 2 diabetes (Type 2 diabetes control group; matched on country, gender, education, diabetes duration and insulin use) and (ii) 93 young adults with Type 1 diabetes (Type 1 diabetes control group; matched on country, gender, age and education). Groups were compared with regard to depression symptoms (nine-item Patient Health Questionnaire), anxiety symptoms (seven-item Generalised Anxiety Disorder questionnaire) and frequency of selected self-care behaviours (single item per behaviour). Participants in the case group had higher depression scores (Cohen's d = 0.40) and were more likely to have clinically meaningful depressive symptoms (Cramer's V = 0.23) than those in the Type 2 diabetes control group. Participants in the case group had statistically equivalent depression scores to the Type 1 diabetes control group. The groups did not differ in anxiety scores. Those in the case group were less likely than both control groups to take insulin as recommended (Cramer's V = 0.24-0.34), but there were no significant differences between the groups in oral medication-taking. The case group were less likely than the Type 2 diabetes control group to eat healthily (Cramer's V = 0.16), and less likely than the Type 1 diabetes control group to be physically active (Cramer's V = 0.15). Our results suggest that Type 2 diabetes is as challenging as Type 1 diabetes for young adults and more so than for older adults. Young adults with Type 2 diabetes may require more intensive psychological and self-care support than their older counterparts. © 2014 The Authors. Diabetic Medicine © 2014 Diabetes UK.

The purpose of the study is to compare the clinico-microbiological profile and treatment outcome of in-house vs referred cases of post cataract surgery endophthalmitis in a tertiary eye care facility in South India. The clinical records of 50 culture-positive cases each of in-house (group A) and referred (group B) post cataract surgery endophthalmitis were analyzed. The management protocol was similar in both groups. The time to report to the institute was longer in group B (group B 13.63 [±11.67; 95% CI, 9.95-17.31] days; group A 6.83 [±7.61; 95% CI, 4.57-9.09] days; P = 0.002). The average inflammatory scores in presentation were comparable (group A 17.85 ± 5.83; group B 18.18 ± 7.35; P = 0.243). The final visual outcome was clinically superior in group A (≥20/200-group A 60.42% and group B 44%, P = 0.11; ≤20/400-group A 37.5% and group B 52%, P = 0.62), but statistically not significant. There were more gram-positive organisms in group A (62% vs 38%; P = 0.027) and more gram-negative organisms in group B (52% vs 24%; P = 0.007). Gram-positive bacteria were mostly sensitive to vancomycin (95.24% to 96.67%), but gram-negative bacteria were partly sensitive to ceftazidime (58.33% to 64%). One could suspect gram-negative infection more often in the referred cases of endophthalmitis. While vancomycin could continue to be the antibiotic of choice in gram-positive bacteria, specific antibiotic following due sensitivity for gram-negative bacteria should replace the empiric use of ceftazidime.

To compare the impact of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) on weight loss and obesity related comorbidities over two year follow-up via case control study design. Forty patients undergoing LRYGB, who completed their two year follow-up were matched with 40 patients undergoing LSG for age, gender, body mass index and presence of type 2 diabetes mellitus (T2DM). Data of these patients was retrospectively reviewed to compare the outcome in terms of weight loss and improvement in comorbidities, i.e ., T2DM, hypertension (HTN), obstructive sleep apnea syndrome (OSAS), hypothyroidism and gastroesophageal reflux disease (GERD). Percentage excess weight loss (EWL%) was similar in LRYGB and LSG groups at one year follow-up (70.5% vs 66.5%, P = 0.36) while it was significantly greater for LRYGB group after two years as compared to LSG group (76.5% vs 67.9%, P = 0.04). The complication rate after LRYGB and LSG was similar (10% vs 7.5%, P = 0.99). The median duration of T2DM and mean number of oral hypoglycemic agents were higher in LRYGB group than LSG group (7 years vs 5 years and 2.2 vs 1.8 respectively, P < 0.05). Both LRYGB and LSG had significant but similar improvement in T2DM, HTN, OSAS and hypothyroidism. However, GERD resolved in all patients undergoing LRYGB while it resolved in only 50% cases with LSG. Eight point three percent patients developed new-onset GERD after LSG. LRYGB has better outcomes in terms of weight loss two years after surgery as compared to LSG. The impact of LRYGB and LSG on T2DM, HTN, OSAS and hypothyroidism is similar. However, LRYGB has significant resolution of GERD as compared to LSG.

The influence of hepatitis B virus (HBV) and hepatitis C virus (HCV) coinfection on liver histology in children remains unknown. We analyzed histopathological features in 70 treatment-naïve children: 10 with HBV/HCV coinfection (case group A), 30 with HBV (control group B), and 30 with HCV (control group C). Liver biopsies were scored for grading and staging according to Knodell's modified system and were tested for an association with demographic and laboratory data. The mean grade was higher in coinfected children compared to control group C (6.2 ± 3.0 vs. 4.2 ± 2.5, p = 0.04), but not control group B (p = 0.47). A higher proportion of patients with moderate to severe necroinflammation were observed in case group A compared to isolated HCV (p = 0.05). Mean staging did not differ between the case and control groups. Multivariate analysis revealed that HBV/HCV coinfection and aminotransferase activity were independently associated with moderate to severe necroinflammatory activity Conclusion: HBV/HCV coinfection was associated with moderate to severe necroinflammation irrespective of age at biopsy or duration of infection and led to significantly higher necroinflammatory activity than HCV monoinfection. HBV/HCV coinfection did not enhance fibrosis. High aminotransferase levels were positively associated with moderate to severe necroinflammation.

The only available treatment that can eliminate the latent hypnozoite reservoir of vivax malaria is a 14 d course of primaquine (PQ). A potential problem with long-course chemotherapy is the issue of compliance after clinical symptoms have subsided. The present study, carried out at an Afghan refugee camp in Pakistan, between June 2000 and August 2001, compared 14 d treatment in supervised and unsupervised groups in which compliance was monitored by comparison of relapse rates. Clinical cases recruited by passive case detection were randomised by family to placebo, supervised, or unsupervised groups, and treated with chloroquine (25 mg/kg) over 3 days to eliminate erythrocytic stages. Individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency were excluded from the trial. Cases allocated to supervision were given directly observed treatment (0.25 mg PQ/kg body weight) once per day for 14 days. Cases allocated to the unsupervised group were provided with 14 PQ doses upon enrollment and strongly advised to complete the course. A total of 595 cases were enrolled. After 9 months of follow up PQ proved equally protective against further episodes of P. vivax in supervised (odds ratio 0.35, 95% CI 0.21-0.57) and unsupervised (odds ratio 0.37, 95% CI 0.23-0.59) groups as compared to placebo. All age groups on supervised or unsupervised treatment showed a similar degree of protection even though the risk of relapse decreased with age. The study showed that a presumed problem of poor compliance may be overcome with simple health messages even when the majority of individuals are illiterate and without formal education. Unsupervised treatment with 14-day PQ when combined with simple instruction can avert a significant amount of the morbidity associated with relapse in populations where G6PD deficiency is either absent or readily diagnosable.

Oral cancer is one of the most common cancers in the world. Although multifactorial, the exact pathogenesis of oral cancer is still unclear. Apart from tobacco chewing and smoking, chronic long-term irritation by ill-fitting denture is also said to be an important risk factor for the development of oral cancer. Literature quotes some amount of evidence that correlates long-term denture irritation as a risk factor for the development of oral cancer. Hence, we analyzed the correlation of denture-related sores as a risk factor for the development of oral cancer. The present case-control study included 140 newly diagnosed oral cancer cases and 140 patients as the control healthy group. One-hour questionnaire was framed and was conducted to the control group and the study group by 10 experienced interviewers who were trained for such type of analysis. Assessment of the patients' socioeconomic status, cigarette smoking habit, alcohol drinking habit, and oral health status was done and compared on the two study groups. Logistic regression models along with multivariate models were used for the assessment of the results. In the control group and the cancer patient group, total of 140 new cancer cases and 140 subjects were included. Out of 140 patients in the cancer group, 16 were nonsmokers, while 110 smoked cigarette in the cancer patient group. As far as alcohol consumption is concerned, 42 patients in the control group and 102 patients in the oral cancer group were chronic heavy drinkers. Fried food intake was high in both the groups. Significant correlation was obtained while comparing the heavy smokers, heavy alcohol consumers, and oral health status in both the study groups. Our results favor the hypothesis that positive correlation exists between oral cancer risk and recurrent denture sores. People wearing denture prosthesis should be periodically visualized for identification of any mucosal alteration or changes at the earliest.

OBJECTIVE A randomized trial that compares clinical outcomes following microsurgery (MS) or stereotactic radiosurgery (SRS) for patients with small- and medium-sized vestibular schwannomas (VSs) is impractical, but would have important implications for clinical decision making. A matched cohort analysis was conducted to evaluate clinical outcomes in patients treated with MS or SRS. METHODS The records of 399 VS patients who were cared for by 2 neurosurgeons and 1 neurotologist between 2001 and 2014 were evaluated. From this data set, 3 retrospective matched cohorts were created to compare hearing preservation (21 matched pairs), facial nerve preservation (83 matched pairs), intervention-free survival, and complication rates (85 matched pairs) between cases managed with SRS and patients managed with MS. Cases were matched for age at surgery (± 10 years) and lesion size (± 0.1 cm). To compare hearing outcomes, cases were additionally matched for preoperative Class A hearing according to the American Academy of Otolaryngology-Head and Neck Surgery guidelines. To compare facial nerve (i.e., cranial nerve [CN] VII) outcomes, cases were additionally matched for preoperative House-Brackmann (HB) score. Investigators who were not involved with patient care reviewed the clinical and imaging records. The reported outcomes were as assessed at the time of the last follow-up, unless otherwise stated. RESULTS The preservation of preoperative Class A hearing status was achieved in 14.3% of MS cases compared with 42.9% of SRS cases (OR 4.5; p < 0.05) after an average follow-up interval of 43.7 months and 30.3 months, respectively. Serviceable hearing was preserved in 42.8% of MS cases compared with 85.7% of SRS cases (OR 8.0; p < 0.01). The rates of postoperative CN VII dysfunction were low for both groups, although significantly higher in the MS group (HB III-IV 11% vs 0% for SRS; OR 21.3; p < 0.01) at a median follow-up interval of 35.7 and 19.0 months for MS and SRS, respectively. There was no difference in the need for subsequent intervention (2 MS patients and 2 SRS patients). CONCLUSIONS At this high-volume center, VS resection or radiosurgery for tumors ≤ 2.8 cm in diameter was associated with low overall morbidity. The need for subsequent intervention was the same in both groups. SRS was associated with improved hearing and facial preservation rates and reduced morbidity, but with a shorter average follow-up period. Facial function was excellent in both groups. Since patients were not randomly selected for surgery, different clinical outcomes may be of different value to individual patients. Both anticipated medical outcomes and patient goals remain the drivers of treatment decisions.

The optimal management of craniopharyngioma is still controversial. The aim of this study is to explore microsurgical outcomes of craniopharyngioma in 335 cases. Clinical data of 335 consecutive patients with craniopharyngioma between March 2011 and March 2017 were retrospectively analyzed. Gross total resection (GTR) was achieved in 265 cases (79.1%), subtotal resection (STR) was obtained in 70 cases (20.9%). The GTR rate was 81.93% in pediatric group and 78.17% in adult group respectively, no significant difference regarding the GTR rate was found in adult group compared with in pediatric group (p > 0.05). However, there was a noticeable difference in the elevated hypothalamic obesity in children group compared with in adult group after operation (p < 0.05). Multivariate analysis indicated that the tumor recurrence and surgical times played a negative role in the resection extent, the odds ratio and 95% confidence interval of the tumor recurrence and surgical times is [0.306 (0.155-0.603), (p < 0.01)] and [2.135 (1.101-4.142), (p < 0.05)] respectively. There was significant difference on panhypopituitarism between GTR and STR group (p < 0.05). However, No significant difference regarding the postoperative visual dysfunction and indepent quality of life respectively between GTR and STR group was found (p > 0.05). Additionally, there were no statistically significant differences for recurrence-free curves between GTR and STR plus adjuvant radiotherapy (p > 0.05). Present findings demonstrated that tumor recurrence and surgical times contribute to negative total resection for craniopharyngioma. Postoperative precise adjuvant radiotherapy was considered in selected cases if pursuit of GTR was rather dangerous under disadvantageous removal factors. Copyright © 2018 Elsevier B.V.

The purpose of this retrospective study was to analyze and compare the clinical and radiologic outcomes of fixed bearing ultracongruent (UC) insert total knee arthroplasty (TKA) and mobile bearing (MB) floating platform TKA using the navigation-assisted gap balancing technique with a minimum follow-up of five years. The study retrospectively enrolled 105 patients who received the UC type fixed bearing insert (group 1) and 95 patients who received the floating platform MB insert (group 2) during the period from August 2009 to June 2012. All surgery was performed using the navigation-assisted gap balancing technique. For strict assessment of gap measurements, the offset-type-force-controlled-spreader-system was used. Radiologic and clinical outcomes were assessed before operation and at the most recent follow-up using the Knee Society Score (KSS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score. For statistical analysis, paired sample t tests were used. A p value less than 0.05 was considered significant. Although the radiologic alignments were satisfactory for both groups (99/105 [94%] cases were neutral for group 1 and 90/95 [94%] for group 2), the functional and total WOMAC scores were inferior in group 2 (p < 0.05). There were two cases of insert breakage in group 2 that required bearing exchange. The Kaplan-Meier survivorship rates for groups 1 and 2 at 77 months were 100.0 and 97.9%, respectively. Second-generation MB floating platform TKA cases did not have satisfactory outcomes. There were two cases of insert breakage, which required bearing exchange. Other patients who underwent surgery with second-generation MB floating platform were encouraged to avoid high knee flexion activities, resulting in lower clinical performance.

To evaluate the success rate of adjustable suture techniques in horizontal eye muscle surgery in children ≤15 years of age over a 19-year period by a single surgeon. The medical records of all consecutive patients in this age group who underwent horizontal eye muscle surgery from 1989 through 2012 were reviewed retrospectively. Patients were divided into two groups: those in whom a nonadjustable suture technique was used and those in whom adjustable sutures were used. The following data were collected: type of strabismus, preoperative measurements, postoperative results, and reoperation rates. A total of 116 cases in the nonadjustable group and 521 cases in the adjustable group were included. In the adjustable group, adjustment was performed in 63% of the cases, because of either an under- (41%) or overcorrection (22%). The adjustment procedure was performed under topical proparacaine in 15% of cases and under intravenous propofol in 85%. For the adjustable group, 3-5 minutes more per muscle intraoperatively and 15-20 minutes for adjustment were required. No complications were encountered during the adjustment procedures. Early success rate, defined as alignment within 8 Δ of straight at 3 to 6 months' postoperative follow-up, was significantly greater in the adjustable group than in the nonadjustable group (77.7% vs 64.6% [P ≤ 0.03]). Of the adjustable patients, 15% required reoperation compared with 21% of the nonadjustable patients. Use of adjustable sutures in horizontal eye muscle surgery in children ≤15 years of age provided an improved success rate and fewer reoperations compared with nonadjustable sutures.

Fecal leakage after open lateral internal anal sphincterotomy for chronic anal fissure is common, but underreported. The aim of this study was to prospectively assess the physiologic and morphologic effects of sphincterotomy, comparing continent and incontinent patients after surgery. This group was further compared with an unselected group of patients presenting with incontinence after hemorrhoidectomy. Between January 1997 and June 1999, 23 patients were prospectively followed up through internal sphincterotomy with conventional and vector volume anorectal manometry, parametric assessment of the rectoanal inhibitory reflex, and endoanal magnetic resonance imaging. Fourteen continent patients were compared with 9 incontinent postoperative cases, 9 patients referred with incontinence after hemorrhoidectomy, and 33 healthy volunteers without anorectal disease. Significant differences were noted between continent and incontinent postsphincterotomy cases for all resting conventional and vector volume parameters and for some squeeze parameters. Although there was a significant reduction in postoperative high pressure zone length at rest, there were no differences between the postoperative groups. There was an increase in sphincter asymmetry of 6.7 percent (+/- 3.5 percent) in incontinent postsphincterotomy patients and a decrease of 2.8 percent (+/- 3.2 percent) in continent cases. Significant differences were noted for resting parameters between incontinent postsphincterotomy and posthemorrhoidectomy patients, with a higher resting sphincter asymmetry in the latter group. The area under the rectoanal inhibitory curve was smaller in postsphincterotomy incontinent patients when compared with continent cohorts over the distal and intermediate sphincter zones at rest with a reduced latency of inhibition. There was no difference in the magnetic resonance images of the sphincterotomy site between incontinent and continent postsphincterotomy cases and no posthemorrhoidectomy case had evidence of sphincteric damage. There are complex significant differences in the postoperative physiology of patients undergoing lateral internal sphincterotomy who become incontinent when compared with those who maintain continence. These physiologic changes are not reflected in detectable morphologic sphincteric differences. It is unknown whether these changes predict for long-term incontinence, and it is suggested that postoperative incontinence after minor anorectal surgery is not necessarily related either to a preexisting sphincter defect or inadvertent intraoperative sphincter injury.

To compare the differences of therapeutic effect of chronic fatigue syndrome treated with the combined therapy of coiling dragon needling and cupping on back and the western medicine therapy with Prednisone. Seventy-two cases were randomly divided into an acupuncture and cupping group (37 cases) and a Prednisone group (35 cases). In acupuncture and cupping group, Jiaji (EX-B 2) points of T1--L5 were applied with coiling dragon needling (once a day), combined with moving cupping on back (once every two days); in Prednisone group, Prednisone tablets were orally taken for 10 mg at 8:00 am. Seven days made one course, and 2 courses were carried on totally. FS-14 scale and BELL's chronic fatigue syndrome integral table were applied to evaluate the fatigue degree of patients before and after treatment, and the therapeutic effects of both groups were compared. After one course of treatment, the BELL's scores of both groups were obviously improved (both P < 0.01), but there was no significant difference between groups (P > 0.05); after two courses of treatment, the BELL's score in acupuncture and cupping group improved more obviously than that in Prednisone group, and the total effective rate of 91.9% (34/37) in acupuncture and cupping group was superior to that of 71.4% (25/35) in Prednisone group (P < 0.05). The therapeutic effect of chronic fatigue syndrome treated with coiling dragon needling and moving cupping on back is positive, superior to that of Prednisone with oral administration.

Purpose To investigate and compare the efficacy of botulinum toxin-A injection in the lacrimal gland and conjunctivodacryocystorhinostomy surgery for the treatment of epiphora caused by proximal lacrimal system obstruction. Methods Charts of the patients with proximal canalicular obstruction who had undergone conjunctivodacryocystorhinostomy with permanent tube insertion (18 patients, group 1) or 4 units of botulinum toxin-A injection in the palpebral lobe of the lacrimal gland (20 patients, group 2) were reviewed retrospectively. The upper lacrimal system obstruction was diagnosed by lacrimal system irrigation. Schirmer-1 test and Munk epiphora grading for evaluation of epiphora were performed before the interventions and on tenth day, first, third, and sixth months after the interventions. Results Improvement of epiphora was statistically significant at all visits when compared with values before injection (P<0.001) in both of groups. When two techniques were compared, difference in degree of epiphora before and after intervention was not statistically significant (P<0.05). In group 2, none of the patients had punctate epitheliopathy, although there was a significant decrease in Schirmer test results (P<0.001, paired t-test). In group 1, 9 cases (50%) had tube dislocation, 4 cases (22.2%) had obstruction, and granuloma formation. Five cases (25%) had ptosis in group 2. Conclusion  Conjunctivodacryocystorhinostomy requires surgical experience, special postoperative care, and multiple revisions. As botulinum toxin-A injection in the lacrimal gland is technically easy, less-invasive, safe, with reversible effects, it can be considered as an alternative treatment in patients with proximal lacrimal system obstruction.

Percutaneous nephrolithotomy (PNL) is the primary treatment modality for management of staghorn stones. PNL in supine position has important advantages over prone positon. However, studies comparing prone and supine positions for PNL in staghorn stone patients have conflicting results, and the aim of the current study was to compare prone and supine positions for PNL in staghorn stone cases. Data of patients underwent PNL for staghorn stones in supine or prone position by a single urologist were collected prospectively. The supine and prone position groups were compared for stone free rate (SFR) and complication rates. All patients were evaluated with NCCT for evaluation of SFR. Chi-square test was used to compare categorical variables and Student t test was applied for continuous variables of the treatment groups. The groups were similar for demographic and stone-related characteristics. Multi-caliceal and intercostal access was more common in prone position. Operation duration was significantly shorter and hemoglobin drop was significantly less in supine group. SFR was 64.1 and 60.4% in the supine and prone groups, respectively (p = 0.72). Complication rates were similar in the two groups but Clavien III complications were observed in two patients in the prone group. PNL in supine position is an effective treatment for management of staghorn stones. The need for multi-caliceal and intercostal puncture is less when combined with retrograde intrarenal surgery. PNL in supine position should be considered as primary treatment option in staghorn stone cases.

The study aims to explore the roles of common polymorphisms of Tumor Necrosis Factor-α (TNF-α) (-238 A/G and -308 A/G) and IL-10 (-819 T/C and -1082 G/A) genes in the risk of non-traumatic osteonecrosis of the femoral head (NONFH). One hundred and forty-seven NONFH patients and 135 healthy individuals were selected as the case and control groups. qRT-PCR and Western blotting techniques detected mRNA as well as protein expressions of TNF-α and IL-10 of each genotype in both the case and control groups. The GA genotype and the A allele of TNF-α -238 A/G were higher in the case group than in the control group. Compared with the control group, AA, GA, and AG + AA genotypes as well as the A allele of IL-10-1082 G/A were all lower in the case group. In the case groups increased levels of TNF-α as well as decreased levels of IL-10 expression when compared with the control group. TNF-α expression of TNF-α-238 GA genotype was significantly higher than that in patients with GG genotype, while the IL-10 expression of GA and AA genotypes of IL-10-1082 was significantly lower than in that of patients with the GG genotype. TNF-α protein expression in the GA genotype was significantly higher than in the GG genotype. In relation to TNF-α -238, TNF-α protein expression of GA and AA genotypes had significantly reduced more so than the GG genotype in IL-10-1082.

The aim of this study was to evaluate the effectiveness of the influenza vaccine used at the Proelmed Medical Center, Poland during the influenza season 1998-1999. The study randomised patients attending the Proelmed Medical Center, Poland to receive influenza vaccination or not. Volunteers were monitored for the following 6 months by interviews at which systemic and local symptoms were recorded. 193 volunteers were randomised to receive influenza vaccine and 206 to the control group. In the vaccinated group, 7 cases (3.7%) of influenza were recorded, compared to 59 cases (28.6%) in the unvaccinated group. Respiratory disease other than influenza occurred in 29.5% of the vaccinated group and 34.5% of the unvaccinated group. Vaccinated patients had a total of 62 days off sick due to influenza, compared to 467 days for the unvaccinated patients. No unexpected adverse events were reported. The influenza vaccine used is highly efficacious in protecting against influenza infection leading to absenteeism from work, and has a good safety profile.

To evaluate the clinical efficacy and safety of tissue-selecting therapy (TST) in treatment of mixed hemorrhoids. A single-blind randomized study was carried out. A total of 120 patients with mixed hemorrhoids from January to December 2012 were prospectively enrolled in the study and equally divided into two groups, TST group and procedure for prolapse and hemorrhoids(PPH) group. Surgical data, efficacy and postoperative complications were compared between the two groups. As compared to PPH group, patients in TST group had shorter operation time [(15.9±5.18) min vs. (22.6±7.1) min, P<0.05], lower scores of rectal urgency (0.5±0.2 vs. 1.5±1.4, P<0.05), and shorter hospital stay [(11.2±3.7) d vs. (14.8±3.7) d, P<0.05]. No anastomotic stricture case was found in TST group, while 11 cases(18.3%) developed anastomotic stricture in PPH group. There were no significant differences in effective rate and pain score of first defecation between the two groups. TST is reliable and safe for mixed hemorrhoids with the advantage of simple, rapid recovery and less complications.

A functional interferon regulatory element (IRE) has been found in the EnhI/X promoter region of hepatitis B virus (HBV) genome. The purpose of this study is to compare the gene order of responder and non-responder to interferon therapy in patients with chronic hepatitis B (CHB), so as to evaluate the relationship between IRE mutation and the response to interferon treatment for CHB patients. Synthetic therapeutic effect is divided into complete response (CR), partial response (PR) and non-response (NR). Among the 62 cases included in this study, 40 cases (64.5%) were in the response group (CR and PR) and 22 (35.5%) cases were in the NR group. Wild type sequence of HBV IRE TTTCACTTTC were found in 35 cases (56.5%), and five different IRE gene sequences. included TTTtACTTTC, TTTCAtTTTC, TTTtAtTTTC, TTTtACTTTt and cTTtACcTTC, were found in 22 cases (35.5%), 1 case (1.6%), 1 case (1.6%), 2 cases (3.2%) and 1 case (1.6%) respectively. There were 41.9%cases (26/62) with forth base C→T mutation, consisted of 32.5% (13/40) cases in response group and 59.1% (13/22) cases in NR group. Among the 35 cases with IRE sequences, there were 67.5% (27/40) cases in response group and 36.4% (8/22) in NR group, and the difference in IRE sequences between two groups was statistic significantly (P = 0.027). The result suggested that there is likely relationship between the forth base mutation (C→T) of IRE region and the response of HBV to Interferon therapy, and this mutation may partially decrease the inhibition effect of interferon on HBV. The forth base C→T mutation in IRE element of HBV may partially influence the response of Interferon treatment in CHB patients.

This commercial field trial compared the efficacy of enrofloxacin and ceftiofur sodium in beef cattle at high risk of developing undifferentiated fever (UF), also known as bovine respiratory disease (BRD) that received tilmicosin at feedlot arrival, were diagnosed and initially treated for UF with tilmicosin, and subsequently required a second UF treatment (first relapse). Feedlot cattle (n = 463) were randomly assigned to 2 experimental groups: ENRO or CEF. Second UF relapse, 3rd UF relapse, overall case fatality and BRD case fatality rates were lower in the ENRO group than in the CEF group (P < 0.05). There were no differences in average daily gain (allocation to re-implant date), chronicity, histophilosis case fatality or miscellaneous case fatality rates between the groups (P ≥ 0.05). A per-animal economic advantage of Can$57.08 was calculated for the ENRO group versus the CEF group. In feedlot cattle in western Canada at high risk of developing UF, it was more cost effective to administer enrofloxacin than ceftiofur sodium for treatment of UF relapse.

2016-02-01

Disability pensions due to skin diseases in Swedish male construction workers were studied by linking data from pension registers and an occupational health service. Incidence rates of disability pensions for cement workers, painters and plumbers were compared with 2 control groups. A total of 623 disability pensions were granted during 4 decades of follow-up. The main diagnoses were eczema (36%) and psoriasis (49%). Pensions were mostly granted in the age range 55-64 years. Among painters, cement workers and plumbers the incidence rates for disability pensions were 33.3, 24.5 and 20.4 cases/100,000 person-years, respectively, compared with 13.7 and 9.2 cases/100,000 person-years in control groups. Relative risks were highest for eczema, and were notable for psoriasis. Attributable fractions for eczema were 90% in cement workers and painters and 75% in plumbers compared with control groups. Attributable fractions for psoriasis in the occupational groups studied were in the range 54-67%. In conclusion, eczema and psoriasis have a high impact on loss of work ability, as reflected by disability pensions.

To compare pregnancy outcomes after transabdominal chorionic villus sampling using biopsy forceps or needle. Retrospective bicentric study including all women who had a transabdominal chorionic villus sampling between 2005 and 2009 (172 using biopsy forceps and 160 using needle). The primary endpoint was the rate of fetal loss, after excluding medical abortion due to the result of the biopsy. The secondary endpoint was the rate of premature rupture of the membrane. All cases were reviewed to try to determine the responsibility of the biopsy. The pregnancy outcomes were not different between the two groups: 4 (4.4%) fetal losses in the biopsy forceps group and 6 (7.4%) in the needle group (P=0.52). Only one case (1.2%) of fetal loss can be attributed to the biopsy, using a needle, and none (0%) following a forceps biospy (P=0.29). The rate of premature rupture of the membrane was comparable in the two groups. The pregnancy outcomes following chorionic villus sampling using a biopsy forceps or a needle seem comparable.

This exploratory case comparison examines the influence of case management activities on engagement and progress in psychotherapy for clients with schizophrenia. Six clients were recruited to participate in ten sessions of Cognitive Behavioral Therapy for psychosis (CBT-p). Three clients who had received Cognitive Behavioral techniques for psychosis (CBt-p, a low-intensity case management intervention) prior to receiving therapy were selected from referrals. A comparison group of three clients who had received standard case management services was selected from referrals. Cases within and across groups were compared on outcome measures and observations from case review were offered to inform future research. Delivering CBT-p services on a continuum from low- to high-intensity is discussed.

To assess the feasibility and outcomes of laparoscopic pyeloplasty in children with complex ureteropelvic junction obstruction (UPJO) and compare to children with iso-lated UPJO without associated urinary tract abnormalities. Medical records of 82 consecutive children submitted to transperitoneal laparoscopic pyeloplasty in a 12-year period were reviewed. Eleven cases were con-sidered complex, consisting of atypical anatomy including horseshoe kidneys in 6 patients, pelvic kidneys in 3 patients, and a duplex collecting system in 2 patients. Patients were di-vided into 2 groups: normal anatomy (group 1) and complex cases (group 2). Demographics, perioperative data, outcomes and complications were recorded and analyzed. Mean age was 8.9 years (0.5-17.9) for group 1 and 5.9 years (0.5-17.2) for group 2, p=0.08. The median operative time was 200 minutes (180-230) for group 1 and 203 minutes (120-300) for group 2, p=0.15. Major complications (Clavien ≥3) were 4 (5.6%) in group 1 and 1 (6.3%) in group 2, p=0.52. No deaths or early postoperative complications such as: urinoma or urinary leakage or bleeding, occurred. The success rate for radiologic improvement and flank pain improvement was comparable between the two groups. Re-garding hydronephrosis, significant improvement was present in 62 patients (93.4%) of group 1 and 10 cases (90.9%) of group 2, p=0.99. The median hospital stay was 4 days (IQR 3-4) for group 1 and 4.8 days (IQR 3-6) for group 2, p=0.27. Transperitoneal laparoscopic pyeloplasty is feasible and effective for the management of UPJO associated with renal or urinary tract anomalies.

Purpose To compare surgical results between conventional intraocular lens (IOL) implantation using an ophthalmic viscosurgical device (OVD) and IOL implantation using a balanced salt solution (BSS) after irrigation/aspiration (I/A) of the lens cortex. Methods A randomized prospective study was conducted on 62 patients who underwent cataract surgery. Following completion of conventional I/A of the lens cortex, we divided patients into two groups according to whether or not BSS was used. In group A (n = 31), the anterior chamber and the capsular bag were completely filled with an OVD before IOL implantation. On the other hand, in group B (n = 31), BSS was irrigated into the anterior chamber through a previous side port during IOL implantation. Surgical results were compared between the two groups. Results In both groups, IOP peaked six hours after surgery. The occurrence of an IOP spike by postoperative day one was observed in six cases (6 / 31) in group A and in no cases (0 / 31) in group B, a difference that was statistically significant (p = 0.024). The values of endothelial cell density, central corneal thickness, anterior chamber inflammation, myopic shift, and posterior capsule opacification were not significantly different between the two groups. Conclusions Compared with the use of OVD for IOL implantation, use of BSS during IOL implantation resulted in reductions in postoperative IOP spike and OVD removal time. PMID:21350689

Childbirth and Diagnosis Related Groups (DRGs): patient classification and hospital reimbursement in 11 European countries.

The study compares how Diagnosis-Related Group (DRG) based hospital payment systems in eleven European countries (Austria, England, Estonia, Finland, France, Germany, Ireland, Netherlands, Poland, Spain, and Sweden) deal with women giving birth in hospitals. It aims to assist gynaecologists and national authorities in optimizing their DRG systems. National or regional databases were used to identify childbirth cases. DRG grouping algorithms and indicators of resource consumption were compared for those DRGs which account for at least 1% of all childbirth cases in the respective database. Five standardized case vignettes were defined and quasi prices (i.e. administrative prices or tariffs) of hospital deliveries according to national DRG-based hospital payment systems were ascertained. European DRG systems classify childbirth cases according to different sets of variables (between one and eight variables) into diverging numbers of DRGs (between three and eight DRGs). The most complex DRG is valued 3.5 times more resource intensive than an index case in Ireland but only 1.1 times more resource intensive than an index case in The Netherlands. Comparisons of quasi prices for the vignettes show that hypothetical payments for the most complex case amount to only € 479 in Poland but to € 5532 in Ireland. Differences in the classification of hospital childbirth cases into DRGs raise concerns whether European systems rely on the most appropriate classification variables. Physicians, hospitals and national DRG authorities should consider how other countries' DRG systems classify cases to optimize their system and to ensure fair and appropriate reimbursement.

Postoperative wound infection also called as surgical site infection (SSI), is a trouble some complication of lumbar spine surgeries and they can be associated with serious morbidities, mortalities and increase resource utilization. With the improvement in diagnostic modalities, proper surgical techniques, antibiotic therapy and postoperative care, infectious complications can result in various compromises afterwards. The objective was to study the relation of surgical site infection in clean lumbar surgeries with the doses of antibiotics. This Retrospective study was conducted at Shifa International Hospital, from January 2006 to March 2008. Hundred post operated cases of lumber disc prolapse, lumbar stenosis or both studied retrospectively by tracing their operated data from hospital record section for the development of surgical site infection (SSI). The patients were divided into three groups depending upon whether they received single, three or more than three doses of antibiotics respectively. Complete data analyses and cross tabulation done with SPSS version 16. Of 100 cases, only 6% had superficial surgical site infection; only 1 case with co morbidity of hypertension was detected. Twenty-one cases had single dose of antibiotic (Group-I), 59 cases had 3 doses (Group-II) and 20 cases received multiple doses (Group-III). There was no infection in Group-I. Only one patient in Group-II and 5 patients in Group-III developed superficial SSI. While 4 in Group-II, 3 in Group-III, and none of Group-I had > 6 days length of stay (LOS). The dose of antibiotic directly correlates with the surgical site infection in clean lumbar surgeries. When compared with multiple doses of antibiotics a single preoperative shot of antibiotic is equally effective for patients with SSI.

To investigate the risk factors, clinical prediction and intrapartum management of shoulder dystocia in non-macrosomia. Totally 7 811 cases of vaginal delivery were retrospectively reviewed from Juanary 2009 to December 2013 in Shengjing Hospital. Shoulder dystocia was found in 11 cases (0.14% , 11/7 811), including 1 case of macrosomia and 10 cases of non-macrosomia (shoulder dystocia group). Each non-macrosomia shoulder dystocia case was matched with 10 cases of normal delivery in the same week, which were selected randomly as the control group. The tendency and risk factors of shoulder dystocia in macrosomia and non-macrosomia were analyzed, and the following data between the two groups were compared, including the height of uterus fundus, abdominal circumference of the pregnant woman, the increasing of body mass index (BMI), fetal biparietal diameter (BPD), fetal femur length (FL), duration of every stage of labor, birth weight of the newborn, head circumference and chest circumference of the newborn, Apgar score. (1) There were 213 macrosomias among the 7 811 vaginal deliveries, with the incidence of 2.73% (213/7 811). Only 1 shoulder dystocia was macrosomia (0.46%, 1/213); while the other 10 cases were non-macrosomia ( 0.13%, 10/7 598). (2) From 2009 to 2013, the macrosomia happened by 24 cases (2.32%, 24/1 034), 42 cases (3.61%, 42/1 164), 46 cases (2.60%, 46/1 772), 62 cases (3.01%, 62/2 060), 39 cases (2.19%, 39/1781), respectively. The incidence of macrosomia had no significant difference among these 5 years (P > 0.05). The shoulder dystosia occurrence without macrosia in these 5 years were 1 case ( 0.10% , 1/1 034), 3 cases (0.26%, 3/1 164), 2 cases ( 0.11%, 2/1 172), 2 cases (0.10%, 2/2 060), 2 cases ( 0.11%, 1/1 781), respectively. The incidence of shoulder dystocia without macrosomia had no significant difference among these 5 years (P > 0.05). (3) In the should dystocia group, 5 cases were complicated with premature rupture of membrane (5/10), 4 cases were mother≥ 35 years old (4/10), 3 cases were multipara(3/10), 3 cases had gestational diabetes mellitus(3/10), 3 cases were occiput posterior during the first stage of labor (3/10), 3 cases had prolonged second stage of labor (3/10) and 6 cases had routine lateral incision (6/10). In the control group, 3 cases were complicated with premature rupture of membrane(3/10); 1 case was mother≥35 years old (1/10); 2 cases were multipara(2/10), 3 cases had gestational diabetes mellitus (3/10), 1 case had prolonged second stage (1/10) and 7 cases had routine lateral incision (7/10). (4) There were no significant difference in the height of uterus fundus, BMI, BPD, FL, and duration of the first stage of labor between the shoulder dystocia group and the control group (P > 0.05). Compared with the control group, the increasing of BMI [(6.8±3.1) vs (4.8±1.4) kg/m(2)], the time of the second stage of labor[(86±65) vs (38±28) minutes ] and abdominal circumference[(108±8) vs (101±7) cm] were significantly higher in the shoulder dystosia group (P < 0.05). (5) There were significant difference in the chest circumference of the newborn [(34.0±1.6) vs (32.2±1.9) cm ] and the ratio of chest circumference to head circumference of the newborn [(0.99±0.03) vs (0.97±0.03) ] between the two groups (P < 0.05). The 1-minute Apgar score of the newborn (7.4±2.8) was significantly lower than the control group (10.0±0.0) (P < 0.01). Clavicular fracture occurred in 3 newborns and brachial plexus injury occurred in 4 newborns in the shoulder dystosia group. It is difficult to predict shoulder dystocia in non-macrosomia. Shoulder dystocia of non-macrosomia could be predicted by measurement of the head circumference, chest circumference, the ratio of chest circumference to head circumference by using prenatal ultrasound. The risk factors may complicated with premature rupture of membrane, abnormal occiput position during the first stage of labor and prolonged second stage of labor.

The clinical outcome of falciparum malaria in endemic areas is influenced by erythrocyte polymorphisms including the ABO blood groups. Studies have reported association of ABO blood group to resistance, susceptibility, and severity of P. falciparum malaria infection. Individuals with blood group "A" have been found to be highly susceptible to falciparum malaria whereas blood group "O" is said to confer protection against complicated cases. We analyzed samples from 293 young children less than six years old with malaria in the Korle-Bu Teaching Hospital in Accra, Ghana. It was observed that group O was present in about 16.1% of complicated cases weighed against 40.9% of uncomplicated controls. Individuals with complicated malaria were about twice likely to be of blood groups A and B compared to group O (A versus O, OR = 1.90, 95% CI = 1.59-2.26, P < 0.0001; B versus O, OR = 1.82. 95% CI = 1.57-2.23, P < 0.0001). Blood group O participants with complicated diseases had low parasitaemia compared to the other blood groups (P < 0.0001). This may give blood group O individuals a survival advantage over the other groups in complicated malaria as suggested. Participants with complicated falciparum malaria were generally anaemic and younger than those with uncomplicated disease.

2016-01-01

The transverse musculocutaneous gracilis (TMG) flap has become a common solution for breast reconstruction. However, the safe skin paddle limits are not yet understood. In this study, we attempted to address this issue based on our experiences with inferior and posterior skin paddle extension. Forty-four breast reconstructions with TMG flaps performed between November 2010 and January 2014 were analyzed retrospectively. For the first 20 cases, the flap skin paddle was extended 3 cm posteriorly to the middle thigh (group 1). For the next 20 flaps (group 2), the posterior tip was limited to this line, whereas more fat was recruited inferiorly. In the four cases of group 3, the skin flap was extended posteriorly with a second vascular pedicle from the profunda artery perforator (PAP) flap. The weights and the dimensions of the flaps, operating durations, and postoperative complications of the entire series were analyzed. Groups 1 and 2 were statistically compared. Flap complications were statistically more frequent in group 1 compared with group 2 (45 vs. 0%, P = 0.0012); 40% posterior flap tip necrosis was observed in group 1. Conversely, donor site complications were statistically more frequent in group 2 than in group 1 (40 vs. 5%, P = 0.019) with 35% inner thigh dehiscence. In the TMG with extended PAP flap group, the operating duration was 77 min longer compared with the rest of the series with no donor site complications. In one case, limited necrosis occurred at the anterior skin tip. Harvesting the posterior portion of the TMG up to the middle of the posterior thigh may lead to partial flap necrosis. Extending subcutaneous fat removal under the inferior skin incision may increase the risk of donor site complications. Adding a second vascular pedicle from the PAP flap may improve posterior TMG tip perfusion at the expense of a longer operation. © 2015 Wiley Periodicals, Inc.

The aim of this study was to investigate the prevalence and intensity of masticatory muscle and temporomandibular joint (TMJ) pain in Croatian war veterans with posttraumatic stress disorder (PTSD). The examined group consisted of 100 Croatian war veterans, in whom PTSD had previously been diagnosed. Patients were compared with 92 subjects who had not taken part in the war and in whom PTSD was excluded by psychiatric examination. The clinical examination consisted of palpation of the masticatory muscles, the prominent neck musculature, and TMJ. The examination technique used and the definition of items were previously tested for reliability and validity. 93% of the subjects with PTSD had masticatory muscle tenderness compared to 45.65% of the subjects in the control group (chi2 = 51.46, p < 0.0001). The most frequent painful location in the subjects with PTSD was the left lateral pterygoid site in 88%, and in subjects of the control group the right lateral pterygoid site in 28.26% of cases. The most painful location in the PTSD group was the left lateral pterygoid site in 72%, and in the control group the left posterior digastric in 4.35% of cases. 58% of the subjects with PTSD had TMJ tenderness compared to 3.26% of subjects in the control group (chi2 = 66.23, p < 0.0001). The most frequent painful location of TMJ in both groups was the left posterior capsule; in the PTSD group 38% and in subjects in the control group 2.17% of cases. The most painful location was the left posterior capsule in 28% of subjects with PTSD, while not one subject in the control group reported severe painful sensitivity. The very high frequency and intensity of pain in subjects with PTSD confirms the effect of stress on muscle and joint sensitivity, i.e. perception of pain.

To determine whether elderly subjects with distinct histories of falls presented differences concerning the influence of sensory interaction on balance. Cross-sectional research. Ninety-six community-dwelling elderly subjects were divided into three groups, according to the history of falls within the past year (group 1, no falls; group 2, one fall; and group 3, recurrent falls). The Clinical Test of Sensory Interaction and Balance was used to evaluate the influence of sensory inputs on standing balance. The test required the subject to maintain stability during 30 s, under six conditions: (i) firm surface with eyes open; (ii) firm surface with eyes closed; (iii) firm surface with visual conflict; (iv) unstable surface with eyes open; (v) unstable surface with eyes closed; and (vi) unstable surface with visual conflict. The time expended on conditions and the number of abnormal cases were compared between groups. Each group was evaluated in relation to its performance in the progression of conditions. More abnormal cases occurred in group 3 compared to group 1 for conditions (iv) and (v); and compared to group 2 for condition (iv). Group 3 remained less time than group 1 under conditions (iv), (v) and (vi). Groups 1, 2 and 3 presented relevant decrements in trial duration from conditions (iv) to (v). For group 3, a significant decay was also noted from condition (i) to (ii). Sensorial interaction in the elderly varies according to their history of falls. Thus, it is possible to correctly guide the rehabilitation process and to prevent sensorial decays according to an individual's history of falls.

The clinical and necropsy findings of all the cases, who died in hospital and had undergone autopsy examination at CMH, Kharian, from January 2001 to December 2003, were retrieved from record of clinical case sheet data and autopsy record of the hospital. The two were analyzed and compared according to the discrepancy classification. The exclusion and inclusion criteria, the international classification of disease (ICD) to code deaths, the global burden of disease (GBD) system to classify and group diseases, and the Goldman discrepancy classification to compare clinical and autopsy diagnosis and classify the discrepancies, were used as described. The death rate varied from 0.94% to 1.29% and autopsy rate from 4.69% to 10.10% annually between January 2001 and December 2003. The number of cases classified according to GBD system was 3 (5%) in Group 1, 26 (43.33 %) in Group 2 and 31 (51.66 %) in Group 3. The discrepancy classes included 9 (15 %) class I major discrepancies and 3 (5 %) class II major discrepancies. Non-discrepant diagnosis was seen in 37 cases (61.66 %) and 11 cases (18.32 %) were non-classifiable. This study showed the usefulness of autopsy findings in the quality improvement of the diagnosis and management of the disease by showing only a minority of cases with discrepant diagnosis of the cause of death.

Background We report the development of a cutaneous melanoma risk algorithm based upon 7 factors; hair colour, skin type, family history, freckling, nevus count, number of large nevi and history of sunburn, intended to form the basis of a self-assessment webtool for the general public. Methods Predicted odds of melanoma were estimated by analysing a pooled dataset from 16 case-control studies using logistic random coefficients models. Risk categories were defined based on the distribution of the predicted odds in the controls from these studies. Imputation was used to estimate missing data in the pooled datasets. The 30th, 60th and 90th centiles were used to distribute individuals into four risk groups for their age, sex and geographic location. Cross-validation was used to test the robustness of the thresholds for each group by leaving out each study one by one. Performance of the model was assessed in an independent UK case-control study dataset. Results Cross-validation confirmed the robustness of the threshold estimates. Cases and controls were well discriminated in the independent dataset (area under the curve 0.75, 95% CI 0.73-0.78). 29% of cases were in the highest risk group compared with 7% of controls, and 43% of controls were in the lowest risk group compared with 13% of cases. Conclusion We have identified a composite score representing an estimate of relative risk and successfully validated this score in an independent dataset. Impact This score may be a useful tool to inform members of the public about their melanoma risk. PMID:25713022

To compare the difference in clinical efficacy on children attention deficit hyperactivity disorder (ADHD) between the combined therapy of scalp acupuncture and EGG biofeedback and the simple EEG biofeedback therapy so as to search the better therapeutic method for ADHD. One hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the simple EEG biofeedback therapy was adopted. In the observation group, on the basis of biofeedback therapy, scalp acupuncture was added and applied to Dingzhongxian (MS 5), Dingpangyixian (MS 8), Baihui (GV 20), Sishencong (EX-HN 1), etc. The ten treatments made one session. After four sessions of treatment, FIQ value in Wechsler intelligence scale, CIH score in Conners children behavior questionnaire, the ratio of 0 wave and p wave in EEG, FRCQ and FAQ in the integrated visual and auditory continuous performance test (IVA-CPT) and clinical comprehensive efficacy were observed before and after treatment in the two groups separately. Three cases were dropped out in the observation group and 2 cases were out in the control group. In the two groups, FIQ, FRCQ and FAQ were all increased after treatment (P < 0.01, P < 0.05); the increases in the observation group were much more significant than those in the control group after treatment (all P < 0.05). In the two groups, CIH score and the ratio of 0 wave and p wave were all reduced after treatment (P < 0.01, P < 0.05); the reduction in the observation group were much more apparent as compared with those in the control group (both P< 0.05). The total effective rate was 91.5% (43/47) in the observation group and better than 83. 3% (40/48, P < 0.01) in the control group. The combined therapy of scalp acupuncture and EEG biofeedback achieves the superior efficacy on children ADHD as compared with the simple biofeedback therapy. This combined therapy rapidly relieves the essential symptoms of ADHD and improves EEG waveform in children patients. Importantly, this therapy obtains and consolidates the significant efficacy.

To explore the role that virtual reality training might play in the learning curve of laparoscopic varicocelectomy. A total of 1326 laparoscopic varicocelectomy cases performed by 16 participants from July 2005 to June 2012 were retrospectively analyzed. The participants were divided into 2 groups: group A was trained by laparoscopic trainer boxes; group B was trained by a virtual reality training course preoperatively. The operation time curves were drafted, and the learning, improving, and platform stages were divided and statistically confirmed. The operation time and number of cases in the learning and improving stages of both groups were compared. Testicular artery sparing failure and postoperative hydroceles rate were statistically analyzed for the confirmation of the learning curve. The learning curve of laparoscopic varicocelectomy was 15 cases, and with 14 cases more, it came into the platform stage. The number of cases for the learning stages of both groups showed no statistical difference (P=.49), but the operation time of group B for the learning stage was less than that of group A (P<.00001). The number of cases of group B for the improving stage was significantly less than that of group A (P=.005), but the operation time of both groups in the improving stage showed no difference (P=.30). The difference of testicular artery sparing failure rates among these 3 stages was proved significant (P<.0001), the postoperative hydroceles rate showed no statistical difference (P=.60). The virtual reality training shortened the operation time in the learning stage and hastened the trainees' steps in the improving stage, but did not shorten the learning curve as expected to.

Transsphenoidal hypophysectomy is becoming progressively less invasive. Recent endoscopic techniques avoid nasal or intraoral incisions, use of nasal speculums, and nasal packing. Several case series of endoscopic endonasal pituitary surgery have been reported, but relatively little data exists comparing complication rates to more traditional approaches. We compare the complications of our first 50 cases of endoscopic, minimally invasive pituitary surgery (MIPS) to our last 50 sublabial transseptal (SLTS) procedures. Retrospective case control study. Fifty consecutive MIPS procedures and 50 consecutive SLTS procedures were reviewed retrospectively. Complication rates were analyzed and compared. Total complications per patient (P = .005), postoperative epistaxis (P = .031), lip anesthesia (P = .013), and deviated septum (P = .028) occurred more often in the SLTS group. No significant difference was seen in cerebrospinal fluid leak, meningitis, ophthalmoplegia, visual acuity loss, diabetes insipidus, intracranial hemorrhage, or death. In the MIPS group, length of stay (P < .001), use of lumbar drainage (P = .007), and nasal packing (P < .001) were also significantly reduced. Endoscopic endonasal pituitary surgery provides improved complication rates when compared with SLTS approaches. In addition, we note advantages of the MIPS approach, including reduced length of hospital stay and decreased use of lumbar drainage and nasal packing.

Four-port bimanual vitrectomy is a surgical technique that facilitates removal of epiretinal membranes in severe proliferative diabetic retinopathy (PDR). As the illumination is held by the assistant through the fourth scleral incision, fibrovascular membranes are removed by bimanual manipulation techniques. The objective of this study was to evaluate the safety and efficacy of four-port bimanual 23-gauge vitrectomy for patients with tractional retinal detachment (TRD) in severe PDR. Retrospective, comparative, consecutive, interventional case series. Sixty-six eyes of 58 consecutive patients who underwent primary vitrectomy for severe diabetic TRD. Thirty-six eyes of 31 cases that were treated with four-port 23-gauge vitrectomy were compared with 30 eyes of 27 cases that were treated with 23-gauge pars plana vitrectomy (PPV). Main outcome measures were best-corrected visual acuity (BCVA), retinal status, intraocular pressure, and incidence of intraoperative and postoperative complications with at least 6 months of follow-up. The primary and ultimate anatomic success rates (94.4% versus 93.3%, and 100% in both groups, respectively) and the mean BCVA changes did not differ significantly between groups. The whole surgical time and the membrane removal time were significantly (p < 0.001, respectively) shorter in the four-port 23-gauge group than in the 23-gauge group. There was no difference in the incidence of intraoperative and postoperative complications in both groups. Four-port bimanual 23-gauge vitrectomy offers comparable anatomic success and shortens the surgical time compared with conventional 23-gauge PPV in patients with TRD resulting from severe PDR. © 2016 Acta Ophthalmologica Scandinavica Foundation.

Many clinicians believe hypercortisolism is ulcerogenic. However, data from clinical studies show that prophylaxis for peptic ulcer disease is no longer recommended in patients receiving corticosteroid treatment. This has not yet been verified in endogenous hypercortisolism by controlled clinical studies. The purpose of the current study was to evaluate the relationship between endogenous Cushing's syndrome (CS) and peptic ulcer disease and Helicobacter pylori infection. The study group contained 20 cases with CS resulting from ACTH-dependent endogenous hypercortisolism. The control groups consisted of 14 age- and gender-matched cases receiving exogenous corticosteroid therapy and 100 cases of dyspepsia with non-cushingoid features. Upper gastrointestinal endoscopy was performed on all cases. Biopsies were taken from five different points: two samples from the antrum, two samples from the corpus, and one sample from the fundus. A histological diagnosis of Helicobacter pylori infection was also obtained from evaluation of biopsy specimens. The frequency of stomach and duodenal ulcers did not vary between the groups (p = 0.5 and p = 0.7). Antral gastritis was less frequent and pangastritis was more common in cases with CS compared to the healthy controls (p = 0.001 and p < 0.001). The incidence of Candida esophagitis was more frequent in cases with CS compared to cases with corticosteroid treatment and healthy controls (p = 0.03). Histopathological findings and frequency of Helicobacter pylori based on pathology results did not vary between the three groups. It is possible that neither exogenous nor endogenous corticosteroid excess directly causes peptic ulcer or Helicobacter pylori infection. Prophylactic use of proton pump inhibitors is not compulsory for hypercortisolism of any type.

The article presents the comparative analysis of techniques of evaluation of costs of hospital treatment using medical economic standards of medical care and clinical statistical groups. The technique of evaluation of costs on the basis of clinical statistical groups was developed almost fifty years ago and is largely applied in a number of countries. Nowadays, in Russia the payment for completed case of treatment on the basis of medical economic standards is the main mode of payment for medical care in hospital. It is very conditionally a Russian analogue of world-wide prevalent system of diagnostic related groups. The tariffs for these cases of treatment as opposed to clinical statistical groups are counted on basis of standards of provision of medical care approved by Minzdrav of Russia. The information derived from generalization of cases of treatment of real patients is not applied.

To explore the clinical characters and histopathologic differences between patients with culture-positive and culture-negative prosthetic joint infection (PJI). Between January 2012 and July 2013, 66 PJI patients in accord with diagnostic criteria were enrolled. According to the results of preoperative aspiration and intraoperative cultures, the patients were divided into culture-negative group (CN group, n = 21) and culture-positive group (CP group, n = 45). There was no significant difference in gender, age, height, weight, and body mass index between 2 groups (P > 0.05). Preoperative C reactive protein (CRP), erythrocyte sedimentation rate (ESR), and prosthesis survival time were compared between 2 groups. Intraoperative frozen sections and paraffin sections were both performed to identify infections, and histological typing was performed according to Morawietz's methods. The preoperative CRP was (1.29 +/- 1.84) mg/dL in CN group and (5.08 +/- 9.57) mg/dL in CP group, showing significant difference (t = 2.094, P = 0.038). The preoperative ESR was (22.86 +/- 28.42) mm/1 h in CN group and (36.74 +/- 31.26) mm/1 h in CP group, showing significant difference (t = 7.761, P = 0.000). The median survival time of prosthesis was 72 months (range, 8-504 months) in CN group and 25 months (range, 15 days-300 months) in CP group, showing significant difference (U = 2.231, P = 0.026). Morawietz's histological typing results showed that 2 cases were rated as type I, 7 cases as type II, and 12 cases as type III in CN group; 6 cases were rated as type I, 25 cases as type II, 13 cases as type III, and 1 case as type IV in CP group. The positive culture rate was 68.18% (45/66), and pathogenic bacteria was dominated by Staphylococcus, accounting for 68.89%. The patients with culture-negative PJI have slow onset and mild inflammatory response, so comprehensive diagnosis should be made based on pathological detection, laboratory examination, and intraoperative cultures.

Case-control studies are often performed to estimate postlicensure vaccine effectiveness (VE), but the enrollment of controls can be challenging, time-consuming, and costly. We evaluated whether children enrolled in the same hospital-based diarrheal surveillance used to identify rotavirus cases but who test negative for rotavirus (test-negative controls) can be considered a suitable alternative to nondiarrheal hospital or community-based control groups (traditional controls). We compared calculated VE estimates as a function of varying values of true VE, attack rates of rotavirus and nonrotavirus diarrhea in the population, and sensitivity and specificity of the rotavirus enzyme immunoasssay. We also searched the literature to identify rotavirus VE studies that used traditional and test-negative control groups and compared VE estimates obtained using the different control groups. Assuming a 1% attack rate for severe rotavirus diarrhea, a 3% attack rate for severe nonrotavirus diarrhea in the population, a test sensitivity of 96%, and a specificity of 100%, the calculated VE estimates using both the traditional and test-negative control groups closely approximated the true VE for all values from 30% to 100%. As true VE decreased, the traditional case-control approach slightly overestimated the true VE and the test-negative case-control approach slightly underestimated this estimate, but the absolute difference was only ±0.2 percentage points. Field VE estimates from 10 evaluations that used both traditional and test-negative control groups were similar regardless of control group used. The use of rotavirus test-negative controls offers an efficient and cost-effective approach to estimating rotavirus VE through case-control studies.

To analyze the learning curve for cancer control from an initial 250 cases (Group I) and subsequent 250 cases (Group II) of robotic-assisted laparoscopic radical prostatectomy (RALP) performed by a single surgeon. Five hundred consecutive patients with clinically localized prostate cancer received RALP and were evaluated. Surgical parameters and perioperative complications were compared between the groups. Positive surgical margin (PSM) and biochemical recurrence (BCR) were assessed as cancer control outcomes. Patients in Group II had significantly more advanced prostate cancer than those in Group I (22.2% vs 14.2%, respectively, with Gleason score 8–10, P= 0.033; 12.8% vs 5.6%, respectively, with clinical stage T3, P= 0.017). The incidence of PSM in pT3 was decreased significantly from 49% in Group I to 32.6% in Group II. A meaningful trend was noted for a decreasing PSM rate with each consecutive group of 50 cases, including pT3 and high-risk patients. Neurovascular bundle (NVB) preservation was significantly influenced by the PSM in high-risk patients (84.1% in the preservation group vs 43.9% in the nonpreservation group). The 3-year, 5-year, and 7-year BCR-free survival rates were 79.2%, 75.3%, and 70.2%, respectively. In conclusion, the incidence of PSM in pT3 was decreased significantly after 250 cases. There was a trend in the surgical learning curve for decreasing PSM with each group of 50 cases. NVB preservation during RALP for the high-risk group is not suggested due to increasing PSM.

The causes of death of 144 Japanese autopsy cases during 1945-1975, who had been intravascularly injected with Thorotrast in life, were compared with those of non-Thorotrast-administered autopsy cases in the same age bracket, recorded in the Annals of Japanese Pathological Autopsy Cases during 1958-1973. This comparison revealed that the incidence of malignant hepatic tumors was more than 10 times higher in the Thorotrast-administered cases. The increase was attributable to an increased incidence of hemangioendothelioma and cholangiocarcinoma of the liver. The only significant increase of liver cirrhosis found to exist in the Thorotrast group occurred in the female cases. Some ofmore » the Thorotrast-administered cases were found to have developed myeloid leukemia and erythroleukemia. There was also a significant increase in the number of cases of aplastic anemia in the Thorotrast group, but clinically and pathologically these were atypical. Lymphatic leukemia was not observed. No significant difference was found in the incidence of either malignant lymphomas or osteosarcomas in the Thorotrast group and the controls. Lung cancer, on the other hand, showed a significantly higher incidence among the controls than among the Thorotrast-administered cases.« less

To observe the clinical characteristics and regular patterns of subacute 1, 2-dichloroethane poisoning patients for providing evidences to it's diagnosis, treatment and prognosis. 51 cases of subacute 1, 2-dichloroethane poisoning analyzed. They were divided into 3 groups according to their main clinical manifestation: group A mainly with intracranial hypertension (n = 25), group B with limbs tremor (n = 18), group C with mental and behavior disorder (n = 8). All cases' clinical symptoms, cranial computer tomography, cerebrospinal pressure (Group A) were observed, the durations of the onset, deterioration, improvement, recovery and whole course of the disease were compared between groups and in each group. In all of 51 cases, only the differences between the deterioration duration of cranial CT and symptom was significantly (t = 2.555, P<0.05), which indicate the deterioration of symptom was earlier than radiological change. The symptom deterioration of group C was the fastest than group A and group B (P<0.00). As to the change of symptom duration, group B's improvement, recovery and whole course was the longest comparing with group A and group C (P<0.05). As to the change of cranial CT duration, group B's recovery duration was the shortest and group A's recovery duration was the longest (P<0.01); group B's whole course was also the shortest and group A's whole course was the longest (P<0.05). The clinical course of symptoms, cranial computer tomography, cerebrospinal pressure (Group A) was compared in each group, in group A, the duration of improvement and whole course of the cranial CT and cerebrospinal pressure change was longer than that of the symptom change (P<0.01), this indicated that group A has longer asymptomatic intracranial hypertension and their cranial radiography recover slowly. In group B, their symptoms (3.94 ± 4.31 days) deteriorated is earlier than cranial CT changes (P<0.05), the recovery (92.39 ± 55.04 days) and whole course of symptom was longer than cranial CT change (all P<0.01). In group C, symptom deterioration was earlier than CT deterioration (P< 0.05). The clinical characteristic of subacute 1, 2- dichloroethane poisoning is central nervous system damage, it differs according to the different stage of course, the regions and severity of pathology lesions.

This paper reports the results of implementing a pilot case management system for work injuries in Hong Kong. The case management approach was characterized by use of a case manager who worked closely with each of the reported injury cases. The case manager undertook the roles of assessor, referral agent, counselor, work-site liaison, and return-to-work (RTW) expert. A quasi-experimental study design was used. The study compared the RTW and workers' compensation outcomes in injured workers in a cleaning company in a case management group (n = 296) and a conventional rehabilitation group (n = 137). Outcomes of the intervention were followed up at 6 months. The results indicated that the RTW rate was 97.0% and 94.2% for the case management and conventional rehabilitation groups respectively, with no significant differences between them. Participants in the case management group had significantly fewer days of sick leave (mean = 27.5 and 41.6 days, respectively) and lower compensation costs (mean = HK$7,212.2 and $20,617.3, respectively) than those in the comparison group. Age of the participants was found to influence the outcomes with those who were between 41 and 50 years old and received case management intervention had shorter sick leave and lower cost of compensation than their conventional rehabilitation counterpart. The majority of the participants who had returned to work in both the case management (95.8%) and the conventional rehabilitation (96.2%) groups were found to maintain their work status 6 months after the intervention. The findings suggested that applying the case management approach to the Hong Kong workers' compensation system was more effective overall. Nevertheless, the inherent problems associated with implementing such an approach within the existing system, which focuses on compensation and medical interventions, remained unresolved.

Several modalities of varicocele treatment are available, however, no therapeutic technique showed its superiority with regard to the other one. To compare the results of three techniques of varicocelecomy. Retrospective Analytical and comparative study of 128 patients treated by of three techniques of varicocelectomy: the open surgery by retro peritoneal way for 42 patients (GI), the varicocelectomie coelioscopique for 41 patients (GII) and the antegrade scrotal sclerotherapy done for 45 patients (GIII), between march 2001 and January 2009.The mean age was 28 years. The main motive for consultation was represented by the painful varicocele in 67 % of the cases, followed by the hypofertility in 20.3 % of the cases and the association both in 12,5 % of the cases. The varicocele was in leftsider in 71.1 % of the cases, to the right side in 5.4 % of the cases and was bilateral in 23.43 % of the cases. Varicocele was infra-clinical at 6 patients, grade 1 in 16 sides, grade 2 in 105 sides and grade 3 in 31 sides. The numeration, the mobility as well as the morphology of sperm cells were comparable between the three groups Results: The global rate success was 81.2 %, with the highest rate found in the group III which was treated by antégrade scrotal sclerotherapy (84.4 %). The improvement of the parameters of the spermogramme was noted in the three groups, however a statistically significant difference was found only in patients treated by antégrade scrotal sclerotherapy; it mainly concerned numeration and the mobility of spermatozoides. The highest rate of pregnancy was recorded in patients treated by antégrade scrotal sclerotherapy (13.3%). The main postoperative complications were hydrocele (16%) followed by testicular hypotrophy (3 patients). Three techniques of varicocele treatment, offer either a similar success rate, and improvement of parameters of the sperm cells. However, antegrade scrotal sclerotherpy seem to be the best treatment of first intention in proposed, regarding its efficiency, of the ease of its realization, its moderate cost and its feasibility in case of recurrence if varicocele was treated with open way'GIII).

Sherlock Holmes and child psychopathology assessment approaches: the case of the false-positive.

To explore the relative value of various methods of assessing childhood psychopathology, the authors compared 4 groups of children: those who met criteria for one or more DSM diagnoses and scored high on parent symptom checklists, those who met psychopathology criteria on either one of these two assessment approaches alone, and those who met no psychopathology assessment criterion. Parents of 201 children completed the Child Behavior Checklist (CBCL), after which children and parents were administered the Diagnostic Interview Schedule for Children (version 2.1). Children and parents also completed other survey measures and symptom report inventories. The 4 groups of children were compared against "external validators" to examine the merits of "false-positive" and "false-negative" cases. True-positive cases (those that met DSM criteria and scored high on the CBCL) differed significantly from the true-negative cases on most external validators. "False-positive" and "false-negative" cases had intermediate levels of most risk factors and external validators. "False-positive" cases were not normal per se because they scored significantly above the true-negative group on a number of risk factors and external validators. A similar but less marked pattern was noted for "false-negatives." Findings call into question whether cases with high symptom checklist scores despite no formal diagnoses should be considered "false-positive." Pending the availability of robust markers for mental illness, researchers and clinicians must resist the tendency to reify diagnostic categories or to engage in arcane debates about the superiority of one assessment approach over another.

Cases in all groups received subtotal course decompression of facial nerve and other compound treatment, and the relationship between handling timing and clinical prognosis were compared. It was found that the difference of prognosis and handling timing was statistically significant, after comparison between all groups with Facial Grading Standards (H-B) as the standard to assess prognosis. Clinical prognosis of cases with Bell palsy was related to alternative handling time, and subtotal course decompression of facial nerve was recommended to be performed as early as possible for those cases who were irresponsive after conservative treatment for one month.

To evaluate clinical results of early total care (ETC) treatment for elderly patients with intertrochanteric femur fractures. Clinical data of 106 elderly patients with intertrochanteric fracture treated from January 2012 and February 2015 were retrospectively studied. According to whether receiving the early total care mode, the patients were divided into 2 groups, 34 cases were diagnosed and treated with early total care pattern (ETC group), including 14 males and 20 females with an average age of (74.88 ± 4.38) years old ranging from 70 to 86. According to Evans types, 4 cases were type I, 5 cases were type II, 13 cases were type III, 11 cases were type IV, 1 case was type V. Seventy-two patients were treated with conventional trauma method (conventional group), including 35 males and 37 females with an average age of (74.46 ± 3.63) years old ranging from 70 to 85. According to Evans type, 8 cases were type I ,13 cases were type II, 25 cases were type III, 25 cases were type IV, and 1 case was type V. All fractures were treated with proximal femoral nails anti-rotation (PFNA). Operative time, hospital stays, leaving bed time, complications, cases of death at 1 year after operation, postoperative Harris score at 12 months were observed and compared. All patients were followed up, the time of ETC group ranged from 9 to 18 months with an average of 13.29 ± 1.51, and the time in conventional group ranged from 12 to 16 months with an average 12.93 ± 1.15, while there was no significant difference between two groups in time of following-up (t = 1.368, P = 0.174). There was no significant meaning in cases of death between ETC group (2 cases) and conventional group (8 cases). Three cases occurred complications in ETC group, and 20 cases in conventional group,there was obvious meaning between two groups (χ² = 0.739, P = 0.318). Operative time,hospital stays,leaving bed time in ETC group respectively was (2.03 ± 0.67) d, (15.41 ± 2.87) d and (3.62 ± 0.74) d; while in conventional group respectively was (4.17 ± 1.59) d, (20.11 ± 4.24) d and (5.35 ± 1.22) d; there were significant differences between two groups in operative time, hospital stays, leaving bed time. Postoperative Harris scores at 12 months in ETC group was (82.32 ± 4.56), and (79.24 ± 5.52) in conventional group, there was obvious meaning between two groups (t = 2.833, P = 0.006). ETC pattern is a novel method for diagnosis and treatment of intertrochanteric femur fractures in elderly, it could shorten operative time, hospital stays, leaving bed time, decrease complications and promote recovery of function.

A case-control study of determinants for high and low dental caries prevalence in Nevada youth

PubMed Central

2010-01-01

Background The main purpose of this study was to compare the 30% of Nevada Youth who presented with the highest Decayed Missing and Filled Teeth (DMFT) index to a cohort who were caries free and to national NHANES data. Secondly, to explore the factors associated with higher caries prevalence in those with the highest DMFT scores compared to the caries-free group. Methods Over 4000 adolescents between ages 12 and 19 (Case Group: N = 2124; Control Group: N = 2045) received oral health screenings conducted in public/private middle and high schools in Nevada in 2008/2009 academic year. Caries prevalence was computed (Untreated decay scores [D-Score] and DMFT scores) for the 30% of Nevada Youth who presented with the highest DMFT score (case group) and compared to the control group (caries-free) and to national averages. Bivariate and multivariate logistic regression was used to analyze the relationship between selected variables and caries prevalence. Results A majority of the sample was non-Hispanic (62%), non-smokers (80%), and had dental insurance (70%). With the exception of gender, significant differences in mean D-scores were found in seven of the eight variables. All variables produced significant differences between the case and control groups in mean DMFT Scores. With the exception of smoking status, there were significant differences in seven of the eight variables in the bivariate logistic regression. All of the independent variables remained in the multivariate logistic regression model contributing significantly to over 40% of the variation in the increased DMFT status. The strongest predictors for the high DMFT status were racial background, age, fluoridated community, and applied sealants respectively. Gender, second hand smoke, insurance status, and tobacco use were significant, but to a lesser extent. Conclusions Findings from this study will aid in creating educational programs and other primary and secondary interventions to help promote oral health for Nevada youth, especially focusing on the subgroup that presents with the highest mean DMFT scores.

To compare the effect and differences sex the influence of hormone levels of perimenopau-sal syndrome patients between manual acupuncture and electroacupuncture (EA). A total of 50 cases with perimenopausal syndrome were randomly assigned into an manual acupuncture group (27 cases) and an EA group (23 cases), and 1 case dropped in the EA group. The acupoints in the two groups were Guanyuan (CV 4), Zigong (EX-CA 1), Tianshu (ST 25), and Sanyinjiao (SP 6). Acupuncture with 3-time small and even manipulation of lifting, thrusting and twirling was used in the acupuncture group, once 10 min. EA with sparse-dense wave and 10 Hz/50 Hz was applied in the EA group for 30 min. The treatments in the two groups were for continuous 8 weeks (24 times in total), once the other day, 3 times a week. The scores of 24-hour hot flashes even, menopausal rating scale (MRS) and menopause-specific quality of life questionnaire (MENQOL) were recorded before treatment and after 4-week and 8-week treatment, as well as 12 and 24 weeks after treatment. Serum sex hormone levels were tested before and after 8-week treatment as well as 12 weeks after treatment, including serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estracliol (E 2 ). Compared with those before treatment, the 24-hour hot flashes even score, MRS and MENQOL scores were significantly lower after 4-week and 8-week treatments, 12 and 24 weeks after treatment (all P <0.05). All the above scores after 8-week treatment were lower than those after 4-week treatment (all P <0.05); and the scores 12 and 24 weeks after treatment were lower than those after 4-week and 8-week treatments (all P <0.05); all the scores after treatment were not significantly different at any time between the two groups (all P >0.05). Compared with those before treatment, serum FSH and E 2 apparently improved in the two groups after 8-week treatment and 12 weeks after treatment (all P <0.05). LH levels did not significantly change in the two groups (all P >0.05). All the serum sex hormone levels showed no significant difference between the two groups (all P >0.05). Both acupuncture and EA can improve perimenopausal symptoms and serum sex hormone. The effects are similar.

Increasing pressure in the clinic requires a more standardized approach to radiostereometric analysis (RSA) imaging. The aim of this study was to investigate whether implementation of personalized RSA patient protocols could increase image quality and decrease examination time and the number of exposure repetitions. Forty patients undergoing primary total hip arthroplasty were equally randomized to either a case or a control group. Radiographers in the case group were assisted by personalized patient protocols containing information about each patient's post-operative RSA imaging. Radiographers in the control group used a standard RSA protocol. At three months, radiographers in the case group significantly reduced (p < 0.001) the number of exposures by 1.6, examination time with 19.2 min, and distance between centrum of prosthesis and centrum of calibration field with 34.1 mm when compared to post-operative (baseline) results. At twelve months, the case group significantly reduced (p < 0.001) number of exposures by two, examination time with 22.5 min, and centrum of prosthesis to centrum of calibration field distance with 43.1 mm when compared to baseline results. No significant improvements were found in the control group at any time point. There is strong evidence that personalized RSA patient protocols have a positive effect on image quality and radiation dose savings. Implementation of personal patient protocols as a RSA standard will contribute to the reduction of examination time, thus ensuring a cost benefit for department and patient safety.

The da Vinci Table Motion (dVTM) is a new device that enables patients to be repositioned with instruments in place within the abdomen, and without undocking the robot. The present study was designed to compare operative and short-term outcomes of patients undergoing colorectal cancer surgery with the da Vinci Xi system, with or without use of the dVTM. Ten patients underwent robotic colorectal resection for cancer with the use of dVTM (Xi-dVTM group) between May 2015 and October 2015 at our center. The intraoperative and short-term clinical outcome were compared, using a case-control methodology (propensity scores approach to create 1:2 matched pairs), with a similar group of patients who underwent robotic colorectal surgery for cancer without the use of the dVTM device (Xi-only group). Overall robotic operative time was shorter in the Xi-dVTM group ( P = .04). Operations were executed fully robotic in all Xi-dVTM cases, while 2 cases of the Xi-only group required conversion to open surgery because of bulky tumors and difficult exposure. Postoperative medical complications were higher in the Xi-only group ( P = .024). In this preliminary experience, the use of the new dVTM with the da Vinci Xi in colorectal surgery, by overcoming the limitations of the fixed positions of the patient, enhanced the workflow and resulted in improved exposure of the operative field. Further studies with a greater number of patients are needed to confirm these benefits of the dVTM-da Vinci Xi robotically assisted colorectal surgery.

Aggressive behavior represents an important public concern and a clinical challenge to behaviorists and psychiatrists. Aggression in humans is known to have an important genetic basis, so to investigate the association of Y chromosome short tandem repeat (Y-STR) loci with initiative-aggressive behavior, we compared allelic and haplotypic distributions of 22 Y-STRs in a group of Chinese males convicted of premeditated extremely violent crimes (n = 271) with a normal control group (n = 492). Allelic distributions of DYS533 and DYS437 loci differed significantly between the two groups (P < 0.05). The case group had higher frequencies of DYS533 allele 14, DYS437 allele 14, and haplotypes 11-14 of DYS533-DYS437 compared with the control group. Additionally, the DYS437 allele 15 frequency was significantly lower in cases than controls. No frequency differences were observed in the other 20 Y-STR loci between these two groups. Our results indicate a genetic role for Y-STR loci in the development of initiative aggression in non-psychiatric subjects. Copyright © 2018 Elsevier B.V. All rights reserved.

To observe wet cupping therapy (WCT) on local blood perfusion and analgesic effects in patients with nerve-root type cervical spondylosis (NT-CS). Fifty-seven NT-CS patients were randomly divided into WCT group and Jiaji acupoint-acupuncture (JA) group according a random number table. WCT group (30 cases) was treated with WCT for 10 min, and JA group (27 cases) was treated with acupuncture for 10 min. The treatment effificacies were evaluated with a Visual Analogue Scale (VAS). Blood perfusion at Dazhui (GV 14) and Jianjing (GB 21) acupoints (affected side) was observed with a laser speckle flflowmetry, and its variations before and after treatment in both groups were compared as well. In both groups, the VAS scores signifificantly decreased after the intervention (P<0.01), while the blood perfusion at the two acupoints signifificantly increased after intervention (P<0.05); however, the increasement magnitude caused by WCT was obvious compared with JA (P<0.05). WCT could improve analgesic effects in patients with NT-CS, which might be related to increasing local blood perfusion of acupunct points.

To test the effects of Nimodipine plus Yufeng Ningxin tablets on frequent migraine. Two hundred forty-two patients with frequent migraine were divided into the control group with those consuming Flunarizine (120 cases) and the treatment group with those consuming Nimodipine plus Yufeng Ningxin tablets (122 cases). The course of frequent migraine treatment lasted 7 weeks. The number of migraine days, visual analogue scale (VAS) score, and response rate were measured. There was significant difference in the cure rate as the Nimodipine plus Yufeng Ningxin tablets group compared with the Flunarizine group (78.7 vs. 21.7%; p < 0.001). Fewer migraine days and VAS score were observed in the treatment group when compared with the control group (p < 0.05). Nimodipine plus Yufeng Ningxin tablets were superior to Flunarizine in terms of the response rate at week 7 (p < 0.05). Due to its high cure rate, treatment with Nimodipine plus Yufeng Ningxin tablets is recommended to control frequent migraine, and this hypothesis needs to be confirmed through further studies conducted on a more extensive population. © 2018 S.

The course of delivery and labor, the post partum period and the postpartal condition of the newborn were reviewed in 315 obese patients with a bodyweight of 90 kg or more at delivery. The results were compared with those of a group of 315 patients with a body-weight of less than 90 kg, choosed by random and evaluated by statistic (t-test, x2-test). In the group of obese gravidae we found a significant higher rate of cases with induction of labor, protracted deliveries, breech presentation and operative deliveries. Also the rate of manual removal of the placenta, post partum uterine infections and disorders in the milk secretion was significant higher in this group. Post partum abnormal glucose tolerance tests ocurred abnormal more frequently in the obese patients. The weight of the infants of obese mothers was higher as in the control group. Significant higher were the perinatal mortality and the cases of fetal death in utero in the obese group compared to the non obese group.

Purpose: To study the fovea in preterm babies with Type I retinopathy of prematurity (ROP) before and after laser treatment using optical coherence tomography (OCT). Materials and Methods: This was a prospective observational case-control study including preterm neonates undergoing screening for ROP from May 2009 to July 2011. Group 1 included 30 eyes of 15 neonates with Type I ROP. A 532-nm laser was used for treatment in all cases for Group 1. Group 2 included 14 eyes of 7 preterm neonates without ROP that served as controls. OCT was performed under sedation in the lateral position before and after laser treatment. P <0.05 was considered statistically significant. Results: The mean initial central macular thickness (CMT) was comparable in both groups (P = 0.832) and statistically significantly correlated with gestational age (P = 0.015). No adverse effects on the anterior segment or posterior segment were observed. There was no significant difference in CMT before and after laser treatment in Group 1 (P = 0.007). There was one case of cystoid macular edema after laser treatment. Conclusion: The macula in preterm babies with Type 1 ROP was comparable to those without ROP. Gestational age was the only predictor of CMT. PMID:25371634

Purpose: To determine the impact of Breast Screen Reader Assessment Strategy (BREAST) over time in improving radiologists' breast cancer detection performance, and to identify the group of radiologists that benefit the most by using BREAST as a training tool. Materials and Methods: Thirty-six radiologists who completed three case-sets offered by BREAST were included in this study. The case-sets were arranged in radiologists' chronological order of completion and five performance measures (sensitivity, specificity, location sensitivity, receiver operating characteristics area under the curve (ROC AUC) and jackknife alternative free-response receiver operating characteristic (JAFROC) figure-of-merit (FOM)), available from BREAST, were compared between case-sets to determine the level of improvement achieved. The radiologists were then grouped based on their characteristics and the above performance measures between the case-sets were compared. Paired t-tests or Wilcoxon signed-rank tests with statistical significance set at p < 0.05 were used to compare the performance measures. Results: Significant improvement was demonstrated in radiologists' case-set performance in terms of location sensitivity and JAFROC FOM over the years, and radiologists' location sensitivity and JAFROC FOM showed significant improvement irrespective of their characteristics. In terms of ROC AUC, significant improvement was shown for radiologists who were reading screen mammograms for more than 7 years and spent more than 9 hours per week reading mammograms. Conclusion: Engaging with case-sets appears to enhance radiologists' performance suggesting the important value of initiatives such as BREAST. However, such performance enhancement was not shown for everyone, highlighting the need to tailor the BREAST platform to benefit all radiologists.

To summarize the features and treatment of male infertility induced by autosomal dominant polycystic kidney disease (ADPKD), and compare the outcomes of intracytoplasmic sperm injection (ICSI) for infertile men with ADPKD and those with congenital bilateral absence of vas deferens (CBAVD). We retrospectively analyzed 21 cases of ADPKD-induced infertility, 15 treated by ICSI (group A), and another 164 cases of strictly matched CBAVD-induced infertility (group B). We compared the two groups in the couples' age, the number of ICSI oocytes, and the rates of fertilization, transferrable embryos, good embryos, embryos implanted, clinical pregnancy, biochemical pregnancy, early abortion, singleton and twins in the first cycle. After 28 cycles of ICSI, 10 of the 15 ADPKD-induced infertility patients achieved clinical pregnancy, including 7 cases of live birth, 1 case of spontaneous abortion, and 2 cases of pregnancy maintenance. No significant differences were observed between groups A and B in the couples' age, the wives' BMI, or the numbers of ICSI oocytes and embryos transplanted (P >0.05), nor in the rates of ICSI fertilization (72.64% vs 76.17%), transferrable embryos (51.28% vs 63.24%), quality embryos (38.46% vs 49.83%), embryo implantation (17.64% vs 38.50%), abortion (0 vs 9.23%), singleton (50% vs 81.54%) and twins (50% vs 18.46%). However, the rates of clinical pregnancy (13.33% vs 42.68%, P = 0.023 <0.05) and biochemical pregnancy (13.33% vs 39.63%, P = 0.032 <0.05) were significantly lower in group A than in B. ICSI is effective in the treatment of male infertility induced by either ADPKD or CBAVD, but the ADPKD cases have a lower success rate than the CBAVD cases in an individual cycle. The affected couples should be informed of the necessity of prenatal genetic diagnosis before embryo implantation and the inevitable vertical transmission of genetic problems to the offspring.

Good oncologic outcomes, demonstrated by a complete pathologic response after preoperative chemoradiotherapy (PCRT), have led to local excision (LE) in selected patients with rectal cancer. We evaluated the oncologic safety of LE compared with total mesorectal excision (TME) in patients with ypT0-T1 rectal cancer.A retrospective review of 304 patients who underwent PCRT, followed by LE or TME, for ypT0-T1 rectal cancer was performed. Propensity scores were computed and used to match groups (LE:TME = 1:1), and analysis of disease-free survival (DFS) and overall survival (OS) was made by comparing patients who underwent LE or TME. Prognostic factors of relapse were analyzed for all patients.Tumor categories were ypT0 in 25 (61.9%) cases, ypTis in 6 (14.3%) cases, and ypT1 in 11 (26.2%) cases for the LE group, and ypT0 in 28 (66.7%) cases, ypTis in 4 (9.5%) cases, and ypT1 in 10 (23.8%) cases for the matched TME patients. There was no significant difference between the matched LE and TME groups in relapse (4.8% and 7.14%, respectively; P = 0.646), 5-year DFS (95.2% vs 91.6%; P = 0.33) and 5-year OS (96.6% vs 88.0%; P = 0.238). In the multivariate Cox regression analysis, tumor distance from the anal verge (hazard ratio [HR] = 0.78; 95% confidence interval (CI) = 0.616-0.992) and the tumor grade (HR = 4.29; 95% CI = 1.430-12.886) were significantly associated with the recurrence risk.LE results in oncologic outcomes that are comparable to those achieved by TME in selected patients with ypT0-T1 rectal cancer after PCRT.

To understand the pathophysiological mechanism of incontinence during orgasm and to compare women affected by symptomatic detrusor overactivity (DO) with and without incontinence at orgasm in terms of efficacy of antimuscarinic treatment. All consecutive sexually active women with incontinence during intercourse were prospectively included and divided into two groups: women with coital incontinence at orgasm or at penetration. The two forms of coital incontinence were correlated to the urodynamic finding of DO. Women complaining of overactive bladder (OAB) symptoms, with urinary incontinence at orgasm and urodynamically proven DO (cases), were prescribed tolterodine 4 mg extended release for at least 12 wk. The cases were compared in terms of efficacy of treatment on OAB symptoms to consecutive patients with symptomatic DO without coital incontinence (control group). Among the 1133 women who underwent urodynamic testings during the study period, 132 patients were eligible for final analysis. A significant difference in DO was observed in women with incontinence at orgasm (34 of 49; 69.4%) compared with women with incontinence during penetration (24 of 83; 28.9%) (p<0.0001). The 34 women with incontinence at orgasm associated with DO were given antimuscarinics treatment and were compared with 53 controls. Fourteen of 34 (41.2%) and 9 of 53 (17%) women did not respond to antimuscarinics in the cases and in the control group, respectively (p=0.023). Incontinence at orgasm is associated with DO in the majority of cases. This is the first study showing an inferior efficacy of antimuscarinic treatment in women with DO complaining of incontinence at orgasm.

Updated and regional data about the circumstances of death and the psychosocial backgrounds of suicides can be helpful for improving suicide-preventive strategies in childhood and adolescence. All known cases of completed suicide in the period from 1996 to 2008 in persons ≤ 21 years of age from the Institute of Forensic Medicine, Frankfurt/Main were analysed in a retrospective study. We included 78 cases and matched them with a comparative sample of 1,797 adult suicides of persons > 21 years of age. Within the chosen period there was a 44 % decrease in incidence of suicide in the group of ≤ 21-year-olds. The fraction of incarcerated persons in this group was 8.0 % compared to 2.56 % in the adult group. Differences from suicide in adulthood were also demonstrated in terms of suicide-related substance abuse (less detection of alcohol, more frequent detection of illicit drugs) and choice of methods (more deaths by being hit by a train). Incarcerated adolescents are an important risk group for suicidal tendency and need increased, well-directed preventive measures. Clinical adolescent psychiatry should pay special attention to the indications in this study of an age-dependent association of drug use in suicide.

Culture-negative periprosthetic joint infection (PJI) is very intractable when dealing with an infected total knee arthroplasty (TKA) patient. Two-stage revision has been proved to be a reliable solution for PJI patients. Whether it is still credible for culture-negative infected patients remains uncertain. Our group retrospectively reviewed all total knee revision patients from January 2003 to January 2014, 145 PJI patients were diagnosed as infection with the PJI diagnostic criteria and 129 patients were successfully followed. As different treating strategies were utilized, these patients were divided into culture-negative (18 cases, CN) group, culture-positive with one-stage revision group (CP1, 21 cases) and culture-positive with two-stage revision group (CP2, 87 cases) groups. The CN group and CP2 group underwent two-stage revision with antibiotic loaded cement spacers and intravenous antibiotics, CP1 group received one-stage revision. All the culture results and relevant medical records were thoroughly reviewed. The mean follow-up time was 59.5 ± 32.3 months (range 12-158 months). The culture-negative rate was 14.2%. The overall infection control rate was 92.12%. Infection recurrence was observed in two cases in CP1 group (9.09%), six cases in CP2 group (6.90%) and two cases in CN group (11.1%). The reinfection rate of culture-negative patients and culture-positive patients was 7.34% and 11.1% with no significant difference (p = 0.94). No statistically difference was observed between CP2 group and CN group (p = 0.90). No Spacer fracture or dislocation was observed. With combined or broad spectrum antibiotics, two-stage revision showed comparable outcome when treating culture-negative infected TKA patients at five-year follow-up. Copyright © 2016.

Background: Substance dependence disorder is a psychiatric disorders with different factors that influence its nature, severity, outcome, and treatment options. Objectives: This study evaluates the effectiveness of Acceptance-Commitment Therapy (ACT) to decrease anxiety and depression in patients with opioid dependencies who are undergoing methadone maintenance treatment (MMT). Materials and Methods: The present study was done in Mashhad from 2011-2012. Twenty-eight patients (18-50 yr) with opioid dependency who were on MMT were selected using purposive sampling and were divided equally between case and control groups. The case group received 8 sessions of individual psychotherapy with ACT. The level of depression and anxiety of these patients were measured using the Beck Depression Inventory-II and Beck Anxiety Inventory before the initiation of ACT as a pretest, 2 weeks after the termination of ACT as the posttest, and 3-months after the termination as a follow-up. The collected data was analyzed with SPSS (ver. 20) using χ2, paired t-test, ANOVA, and MANOVA. Results: The pretest-posttest-follow up of anxiety showed no significant differences between the two groups (P = 0.05); however, the case group had lower depression scores in the posttest and follow-up than the control group (P = 0.04). Evaluating the results of the case group revealed that depression significantly decreased in the posttest group when compared to the pretest (P = 0.01) and there were no significant decreases in the follow up compared to the pretest (P = 0.34). Conclusion: Short-term ACT for opioid dependent patients on MMT are not associated with a significant decrease in the level of anxiety; however, it is associated with a significant decrease in the level of depression. Nonetheless, this reduction was not maintained long term. PMID:26251660

Although oncoplastic breast surgery is used to resect larger tumors with lower re-excision rates compared to standard wide local excision (sWLE), criticisms of oncoplastic surgery include a longer-albeit, well concealed-scar, longer operating time and hospital stay, and increased risk of complications. Round block technique has been reported to be very suitable for patients with relatively smaller breasts and minimal ptosis. We aim to determine if round block technique will result in operative parameters comparable with sWLE. Breast cancer patients who underwent a round block procedure from 1st May 2014 to 31st January 2016 were included in the study. These patients were then matched for the type of axillary procedure, on a one to one basis, with breast cancer patients who had undergone sWLE from 1st August 2011 to 31st January 2016. The operative parameters between the 2 groups were compared. 22 patients were included in the study. Patient demographics and histologic parameters were similar in the 2 groups. No complications were reported in either group. The mean operating time was 122 and 114 minutes in the round block and sWLE groups, respectively (P=0.64). Length of stay was similar in the 2 groups (P=0.11). Round block patients had better cosmesis and lower re-excision rates. A higher rate of recurrence was observed in the sWLE group. The round block technique has comparable operative parameters to sWLE with no evidence of increased complications. Lower re-excision rate and better cosmesis were observed in the round block patients suggesting that the round block technique is not only comparable in general, but may have advantages to sWLE in selected cases.

To compare the outcomes of flexible ureterorenoscopy and lasertripsy (FURS) using digital and conventional FURS for kidney stones. From September 2007 to April 2011, 118 patients underwent FURS (by the same surgeon). The outcomes were compared between equal numbers of procedures (59 each) using a conventional flexible ureterorenoscope (C-FURS; Olympus URF-P5) and a digital flexible ureterorenoscope (D-FURS; Olympus URF-V). Although the deflection, working channel, and field view are similar in both, the initial and terminal diameter is 8.4F and 9.9F and 6.9F and 8.4F for the D-FURS and C-FURS, respectively. The mean stone fragmentation time was calculated by the size per operative time. The preoperative, operative, and postoperative data were retrospectively analyzed and compared. The patient demographics were comparable. The mean stone size was 12.8 and 12 mm in the C-FURS and D-FURS groups, respectively. The initial assessment of the entire pyelocaliceal system was possible in 58 of 59 cases (98%) in the C-FURS group and 56 of 59 cases (94%) in the D-FURS group. The mean operative time was significantly longer in the C-FURS group (53.8 ± 15.2 minutes vs 44.5 ± 14.9 minutes). The overall stone-free rate 1 month after the procedure was 86% in the C-FURS group and 88% in the D-FURS group. Although on comparison, the D-FURS had slightly limited maneuverability, comparable success rates can be achieved with both conventional and digital ureteroscopes. D-FURSs significantly reduced the operative time compared with C-FURSs. Copyright © 2013 Elsevier Inc. All rights reserved.

To compare differences between Crowe IV developmental dysplasia of the hip (DDH) with secondary acetabulum and Crowe IV DDH without secondary acetabulum,and determine whether it is necessary to divide Crowe IV DDH into two subtypes. From June 2007 to May 2015,145 hips of 112 Crowe N patients who underwent total hip arthroplasty (THA) using S-ROM stem were divided into two groups: secondary acetabulum formaton group (group A) and no secondary acetabulum formaton group (group B). In group A,there were 12 females, 96 males,with an average age of (39.38 ± 11.19) years old. In group B, there were 2 females, 35 males, with an average age of (38.19 ± 10.92) years old. All the patients were evaluated by using Harris Hip Score. Radiographic evaluations were made preoperatively and during follow up. The differences between two groups were compared on dislocation height, canal flare index (CFI), subtrochanteric shortening osteotomy (SSTO) usage, pre- and post-operation Harris scores, complications. The dislocation height for group A was (4.74 ± 1.57) cm, while the dislocation height for group B was (3.12 ± 1.15) cm. Significantly difference was detected between two groups. The CFI for group A was 2.69 ± 0.68, while the CFI for group B was 3.42 ± 0.79, and the significantly difference was detected between two groups. Harris scores were totally improved from 58.18 ± 15.67 preoperatively to 91.20 ± 3.79 post-operatively and the difference was significant. Pre-operative Harris scores was 58.1 ± 15.3 in group A, 58.3 ± 16.9 in group B. Post-operative Harris scores was 91.0 ± 4.1 in group A, 91.0 ± 5.1 in group B. No significant difference was found on Harris scores between A and B preoperatively and post-operatively. Complications of 4 cases peri-prosthesis fracture, 4 cases dislocation and 4 cases nerve injury occur in group A; While only one case dislocation and one case nerve injury occur in group B. No statistical significance was detected. Crowe IV DDH with secondary acetabulum is significantly different from Crowe IV DDH without secondary acetabulum on dislocation height and femoral morphology, which causes the different selections of surgical techniques (SSTO usage or not). These important differences in fundamental parameters indicate the necessity to further divide Crowe IV DDH into IVA and IVB two subtypes.

To compare the clinical, socioeconomic and demographic characteristics of individuals diagnosed with Neisseria gonorrhoeae (NG) in the community using a concomitant nucleic acid amplification test (NAAT, AptimaCombo2) as part of the (community-based) UK Chlamydia Screening Programme (CSP), with those diagnosed in hospital-based genitourinary medicine (GUM) services. A retrospective case note review of all 643 patients treated for NG at a GUM in north west England (January 2007-April 2009). All 643 treated for NG (including CSP cases, since all cases were referred to GUM for treatment). Limited data were available for 13 CSP cases who failed to attend GUM. Whether the case was detected in the community or GUM services. Predictors were demographics (age, gender, postcode for deprivation analysis), sexual history (eg, number of partners) and clinical factors (eg, culture positivity). 131 cases were diagnosed by CSP (13 of whom did not attend GUM). A further four cases were contacts of these. The GUM caseload was thus inflated by 23% (from 521 to 643). Community cases were overwhelmingly female (85% vs 27% in GUM, p<0.001) and younger (87% females were <25 years vs 70% GUM females, p=0.001). Logistic regression analysis restricted to the target age of the CSP (<25 years) revealed that CSP cases, compared with GUM cases, were more likely to reside in deprived areas (adjusted OR=5.6, 95% CI 1.4 to 21.8 and 5.3, CI 1.7 to 16.6 for the most and second most deprived group respectively, compared with the averagely deprived group, p=0.037) and be asymptomatic (adjusted OR=1.9, CI 1.1 to 3.4, p=0.02). Community screening for NG led to a 79% increase in the number of infections detected in women aged <25 years. Screening is targeted at young people, and tends to disproportionately attract young women, a group under-represented at GUM. Screening also contributed further to case detection in deprived areas.

We aimed to explore the feasibility and the safety of the laparoscopic surgery for incarcerated indirect inguinal hernia (IIH) in children. From January 2012 to December 2014, 64 children were enrolled into this study. All 64 patients received laparoscopic surgery and we reviewed their perioperative and postoperative follow-up studies. In addition, we enrolled 60 cases of children who received traditional surgery of IIH administered through minimally invasive surgery as the control group. Results from the present study showed that the mean operation time for the laparoscopic group was 41.5 min (range, 15-80 min) which was significantly shorter than the control group. Nine cases developed incarcerated intestine necrosis, expanded umbilical incision and parallel resection anastomosis. They received laparoscopic hernia sac high ligation. Only 5 cases developed scrotum edema after the surgery. The postoperative length of the stay ranged from 2 to 7 days (average, 3.2). The postoperative follow-up was from 6 months to 1 year and no relapse or secondary testicular atrophy was observed in the laparoscopic group. The operation time, incidence of postoperative complications and length of stay in the laparoscopic group were decreased compared to the control group, and differences were statistically significant (P<0.05). In conclusion, laparoscopic surgery treatment for incarcerated inguinal hernia is safe and feasible and produced better results compared with the alternative.

This study aimed to evaluate dietary nutrient intake among Chinese pregnant women by comparison with Chinese Dietary Reference Intakes (DRIs) and to explore the association between dietary nutrients and preterm birth. A case-control design was conducted in Beijing with 130 preterm delivery mothers in case group and 381 term delivery mothers in control group. Information on mothers' diet was collected using a food frequency questionnaire, and nutrients and energy intakes were subsequently calculated based on DRIs. Multivariate analysis of variance was used to compare the differences between term and preterm groups in relation to dietary nutrients. Dietary nutrient intakes were imbalanced in both groups compared with Chinese DRIs. Preterm delivery mothers had a lower level of fat and vitamin E intake than term delivery mothers (p < 0.05). Multivariate analysis showed lower vitamin E intake in preterm delivery mothers with a prepregnancy BMI < 18.5 kg/m2 (p < 0.05) and higher carbohydrate intake in preterm delivery mothers with prepregnancy BMI ≥ 24 kg/m2 (p < 0.05). An imbalanced diet in both groups and low level of dietary intakes of fat and vitamin E in preterm group suggest health education measures should be taken to improve the dietary quality of pregnant women, especially for those with an abnormal prepregnancy BMI.

The purpose of this study is to compare the clinical outcomes of surgical management by one-stage posterior debridement, transforaminal lumbar interbody fusion (TLIF) and instrumentation and combined posterior and anterior approaches for lumbar spinal tuberculosis, and determine the clinical effectiveness of the posterior only surgical treatment for lumbar spinal TB at the same time. Thirty-seven patients who suffered lumbar tuberculosis were treated by two different surgical procedures in our center from May 2004 to June 2012. All the cases were divided into two groups: 19 cases in Group A underwent one-stage posterior debridement, TLIF and instrumentation, and 18 cases in Group B underwent posterior instrumentation, anterior debridement and bone graft in a single-stage procedure. The operation time, blood loss, lumbar kyphotic angle, recovery of neurological function and fusion time were, respectively, compared between Group A and Group B. The average follow-up period for Group A was 46.6 ± 16.7 months, and for Group B, 47.5 ± 15.0 months. It was obvious that the average operative duration and blood loss of Group A was less than those of Group B. Lumbar tuberculosis was completely cured and the grafted bones were fused in 10 months in all patients. There was no persistence or recurrence of infection and no differences in the radiological results in both groups. The kyphosis was significantly corrected after surgical management. The average pretreatment ESR was 60.7 ± 22.5 mm/h, which became normal (9.0 ± 2.8 mm/h) within 3 months in all patients. Surgical management by one-stage posterior debridement, TLIF and instrumentation for lumbar tuberculosis is feasible and effective. This approach obtained better clinical outcomes than combined posterior and anterior surgeries.

Introduction: Patients with threatened miscarriage associated with adverse pregnancy outcomes because of associated pregnancy and labor complications. Objectives: To evaluate the effect of threatened miscarriage on early and late pregnancy outcome. Methods: A retrospective case–controlled study was performed on 89 women with threatened miscarriage (study group) at Maternity and Children Hospital Buraidah, KSA from January 2010 to December 2010. They were matched for age and parity to 45 cases (control group) attending route antenatal clinic at the same time. Data recorded included, demographic characteristics and detailed pregnancy outcome and ultrasound finding including gestational age, cardiac activity and subchorionic hematoma. Results: The overall adverse pregnancy outcome was significantly higher in the studied cases compared to the control group (p=015).The miscarriage rate was significantly higher in study group compared to the controls group, (16.9%vs 2.2%, p=0000). Preterm delivery, babies with low birth weight and premature rupture of membranes were significantly higher in the miscarriage group compared to the controls group, (15.7% vs 2.2%, p=0.001), (15.7% vs 2.2%), p=0.001) and (6.7%) vs 4.45), p=0.016). There were no significant differences in other pregnancy outcomes. Conclusion: threatened miscarriage is associated with increased incidence of adverse pregnancy outcome. The risk is specially increased in premature rupture of the membranes, preterm delivery and neonatal birth weight. PMID:23678307

To explore the impact of microwave dealing with cutting surface on perioperative liver function recovery and recurrence and metastasis after hepatectomy for HCC. Clinical data of 133 patients with HCC from March 2009 to November 2010 were retrospectively analyzed. They were divided into the conventional surgery group (66 cases) and microwave treatment group (67 cases). A domestic ECO-100 microwave knife was inserted into the liver cutting surface 0.5 cm from the cutting edge, and repeated multi-point burning with an average time of 25 minutes in the microwave treatment group. Then the perioperative liver function recovery and recurrence and metastasis in the two groups were compared. The operation time of conventional surgery group was (158.0 ± 31.0) minutes, and that of microwave treatment group was significantly longer (181.0 ± 28.0) minutes (P=0.027). There were no significant differences in the liver function recovery between the two groups (P>0.05). There were 6 cases of recurrence and metastasis after 6 months and 9 cases after 12 months in the microwave treatment group, while there were 15 cases of recurrence and metastasis after 6 months and 20 cases after 12 months in the conventional surgery group, showing a significant difference (P=0.034 and 0.022, respectively). Microwave dealing with the cutting surface has no significant effect on perioperative liver function recovery in hepatectomy. However, microwave treatment can reduce the in situ recurrence in HCC patients within the first year after surgery, indicating a good clinical application value.

Interprofessional education (IPE) provides students with opportunities to learn about the roles and responsibilities of other professions and develop communication and teamwork skills. As different health professions have recognised the importance of IPE, the number of disciplines participating in IPE events is increasing. Consequently, it is important to examine the effect group structure has on the learning environment and student knowledge acquisition during IPE events. The purpose of this study was to determine the effect of group composition on student perceptions of interprofessional teamwork and collaboration when participating in a case-based IPE forum. To examine this construct, six cohorts of students were divided into two groups: Group-one (2010-2012) included students from five professions. Group-two (2013-2015) included students from 10 professions. The only other change for group-two was broadening the case scenarios to ensure a role for each profession. At the conclusion of the case-based IPE forums, both groups demonstrated a statistically significant increase in 'readiness for interprofessional learning' and 'interdisciplinary education perceptions'. However, participants in group-one (2010-2012) demonstrated a greater change in scores when compared to group-two (2013-2015). It was concluded a case-based IPE forum with students from numerous health professions participating in a discussion about broad case scenarios was moderately effective at introducing students to other health professions and increasing their knowledge of others' identities. However, a smaller grouping of professions with targeted cases was more effective at influencing student perceptions of the need for teamwork. When planning an IPE event, faculty should focus on intentional groupings of professions to reflect the social context of healthcare teams so all students can fully participate and experience shared learning.

Cholecystectomy and Diagnosis-Related Groups (DRGs): patient classification and hospital reimbursement in 11 European countries.

As part of the EuroDRG project, researchers from eleven countries (i.e. Austria, England, Estonia, Finland, France, Germany, Ireland, Netherlands, Poland, Sweden, and Spain) compared how their Diagnosis-Related Groups (DRG) systems deal with cholecystectomy patients. The study aims to assist surgeons and national authorities to optimize their DRG systems. National or regional databases were used to identify hospital cases with a procedure of cholecystectomy. DRG classification algorithms and indicators of resource consumption were compared for those DRGs that individually contained at least 1% of cases. Six standardised case vignettes were defined, and quasi prices according to national DRG-based hospital payment systems were ascertained and compared to an index case. European DRG systems vary widely: they classify cholecystectomy patients according to different sets of variables into diverging numbers of DRGs (between two DRGs in Austria and Poland to nine DRGs in England). The most complex DRG is valued at four times more resource intensive than the index case in Ireland but only 1.3 times more resource intensive than the index case in Austria. Large variations in the classification of cholecystectomy patients raise concerns whether all systems rely on the most appropriate classification variables. Surgeons, hospital managers and national DRG authorities should consider how other countries' DRG systems classify cholecystectomy patients in order to optimize their DRG systems and to ensure fair and appropriate reimbursement.

Few studies have looked at lung cancer in prisoners, despite this population is possibly at increased risk of malignancy. In a previous study, we found an early onset of lung cancer in prisoners. Thus, the present CARCAN study was aimed at assessing the epidemiological characteristics, management, prognosis, and incidence of lung cancer in prisoners compared to a sample of non-prisoner patients. We performed a multi-center observational case-control study. Cases were prisoners diagnosed with lung cancer from 2005 to 2013. Controls were non-prisoner lung cancer patients selected from hospital databases and randomly matched to cases (targeted case-control ratio: 1:3). Incidence rates in both groups were calculated using national statistics. Seventy-two cases and 170 controls met inclusion criteria. Cases were mainly men (99%). Mean age at diagnosis was 52.9 (± 11.0) in cases and 64.3 (± 10.1) in controls (p < 0.0001). More case patients were current smokers compared to control patients (83% vs 53%; p < 0.0001). We found no significant differences between the two groups as concerns histologic types, TNM stages at diagnosis, initially-employed treatments, times to management or survival. Incidence rates (2008-2012) in male prisoners were higher than those in the general population in all concerned age groups. There is a shift of lung cancer toward young people in prisons. However, the presentation, management, and prognosis of lung cancer are similar between prisoners and non-prisoners. These finding could justify a specific screening policy for the incarcerated populations.

Purpose This study aimed to compare the learning curves and early postoperative outcomes for conventional laparoscopic (CL) and single incision laparoscopic (SIL) right hemicolectomy (RHC). Methods This retrospective study included the initial 35 cases in each group. Learning curves were evaluated by the moving average of operative time, mean operative time of every five consecutive cases, and cumulative sum (CUSUM) analysis. The learning phase was considered overcome when the moving average of operative times reached a plateau, and when the mean operative time of every five consecutive cases reached a low point and subsequently did not vary by more than 30 minutes. Results Six patients with missing data in the CL RHC group were excluded from the analyses. According to the mean operative time of every five consecutive cases, learning phase of SIL and CL RHC was completed between 26 and 30 cases, and 16 and 20 cases, respectively. Moving average analysis revealed that approximately 31 (SIL) and 25 (CL) cases were needed to complete the learning phase, respectively. CUSUM analysis demonstrated that 10 (SIL) and two (CL) cases were required to reach a steady state of complication-free performance, respectively. Postoperative complications rate was higher in SIL than in CL group, but the difference was not statistically significant (17.1% vs. 3.4%). Conclusion The learning phase of SIL RHC is longer than that of CL RHC. Early oncological outcomes of both techniques were comparable. However, SIL RHC had a statistically insignificant higher complication rate than CL RHC during the learning phase. PMID:25960990

This study was designed to investigate the antioxidant effects of Naringin, in ischemia/reperfusion (I/R)-induced skeletal muscle injury in rats. The rats were randomly allocated into three groups including control, I/R and I/R + Naringin groups. Muscle tissues of I/R groups revealed significantly higher antioxidant enzyme activities, and increased levels of malondialdehyde, as specific a marker of the lipid peroxidation and tissue damage, compared to the control group (p < 0.05). Levels of these parameters in muscle revealed significant reductions in the I/R + Naringin group compared to the I/R group (p < 0.05). Histopathological examination of ischemia muscles in the I/R group showed significant degeneration and inflammation compared to the control group, whereas ischemic muscles of Naringin-administered group showed significant reduction in degeneration and inflammation compared to the I/R group (p < 0.05). We suggest that the protective effect of Naringin may reduce the I/R injury in cases of extremity injuries with acute vascular complications, extremity surgery with prolonged tourniquet application.

Canine screw-worm myiasis due to Cochliomyia hominivorax or Chrysomya bezziana has traditionally been treated with extra-label use of ivermectin. The larvicidal activities of nitenpyram and spinosad/milbemycin also have been described, but there have been no reports to describe the efficacy of isoxazolines such as afoxolaner. To evaluate and compare the efficacy of spinosad, spinosad/milbemycin, milbemycin, nitenpyram and afoxolaner for the treatment of canine screw-worm myiasis. Forty client-owned and naturally infested dogs. Cases were randomized into five groups of eight dogs, with each receiving an insecticide at the dose recommended by the manufacturer. Each case was evaluated hourly for 7 h and then again 24 h after treatment. Scores of 0 (no visualized effect), 0.5 (partial eradication) or 1 (complete kill and eradication) were recorded at each observation and compared between groups. Time to complete killing of all larvae was recorded for each dog and compared between treatment groups. Nitenpyram killed all larvae at 6 h post-consumption and spinosad/milbemycin at 7 h. In groups receiving afoxolaner or spinosad, all larvae were killed within 24 h. For those receiving milbemycin, two cases were still infested with live larvae at 24 h. Shih tzus and their crosses were most commonly affected. Spinosad/milbemycin or nitenpyram seem to be effective drugs for the treatment of canine screw-worm myiasis. Afoxolaner and milbemycin are effective but exhibited slower larvicidal activity. Synergism between spinosad and milbemycin was observed. © 2018 ESVD and ACVD.

Management of AO type B and C fractures of the distal radius is controversial. This study compares outcomes and complications of AO type B and C fractures of the distal radius treated with volar locked plating and nonoperative methods. Sixty-four patients with fractures of the distal radius (AO type B and C) were included in this study, according to inclusion criteria, and were allocated to the volar plating group or nonoperative group by alternate randomization: 32 patients with odd numbers went into the nonoperative group and the other 32 with even numbers went into the volar plating group. Patients in the nonoperative group were managed with closed reduction of the fracture and plaster cast application under an image intensifier. Those in the volar plating group were managed by open reduction and fixation with a volar locked plate. Preoperative and postoperative serial clinico-radiological follow-up was done. The range of movement, grip strength, functional outcome scores and radiological parameters were compared. Student's t-test was used for statistical analysis with significance at p < 0.05. Range of movement and functional scores were significantly (p < 0.001) better in the volar plating group, but the difference in ulnar variance and radial and ulnar deviation was insignificant as compared to the nonoperative group. At 24 months follow-up, the nonoperative group had significantly more cases with malunion, articular incongruity and osteoarthritis. In cases of AO type B or C fractures of the distal radius, volar locked plating provides anatomical stable fixation and early mobilization with better clinico-radiological outcome as compared to conservative treatment.

The aim was to compare the postoperative efficacy of the PDS II and Ethibond W4843 sutures in fresh, closed Achilles tendon rupture. With methods of random grouping (level of evidence II b), a total of 128 patients with fresh Achilles tendon rupture were operated on with PDS II or Ethibond W4843 suture. Postoperative objective examination and the American Orthopaedic Foot & Ankle Society (AOFAS) scoring system were used for the evaluation. Group A underwent 12-39 months of follow-up, for an average of 22 months. Group B underwent 12-37 months of follow-up, for an average of 23 months. The postoperative AOFAS score of group A within 3 months was 93 ± 9.6 points. One case exhibited re-rupture, five cases exhibited incision infection, one case manifested deep infection, and seven cases exhibited Achilles tendon adhesion. The postoperative AOFAS score of group B within 3 months was 97 ± 7.8 points. Eleven cases had incision infection, and 13 cases manifested Achilles tendon adhesion. Minimal differences were observed in the incision infection, re-rupture rate, and Achilles tendon adhesion in the study of the PDS II and Ethibond W4843 sutures. But, based on the AOFAS score and pain score, the Ethibond suture performed better.

Technology has become an important teaching tool in the blended classroom to enhance group based learning experiences. Faculty evaluation of classroom technologies is imperative prior to adoption. Few studies have directly compared various technologies and their impact on student satisfaction and learning. The purpose of this study was to evaluate technology enhanced teaching methods on the learning and satisfaction of graduate students in an advanced pharmacology class using an unfolding case study. After IRB approval, students were randomly assigned to one of three groups: blogging group, wiki group or webinar group. Students completed the evolving case study using the assigned interactive technology. Student names were removed from the case studies. Faculty evaluated the case study using a rubric, while blinded to the assigned technology method used. No significant difference was found on case study grades, the range of grades on the assignment demonstrated little differences between the methods used. Students indicated an overall positive impact related to networking and collaboration on a satisfaction survey. Impact of technology methods needs to be explored in other areas of graduate nursing education. Copyright © 2016 Elsevier Ltd. All rights reserved.

Arthroscopic debridement has been a gold standard procedure for anterior ankle impingement, both in cases of osseous and soft tissue impingement. There is sparse literature on comparative outcome with respect to functional results between the two types of impingement post-arthroscopic debridement. Our study included 14 patients diagnosed as cases of anterior ankle impingement on the basis of clinical and radiological examination. They were segregated into two groups (on the basis of cause of impingement (osseous versus soft tissue)). Both groups were treated by arthroscopic debridement. Primary outcome was patient satisfaction, which was assessed by Likert scale and clinical outcomes were measured using AOFAS ankle-hind foot scale, VAS score, range of motion and time to return to pre-injury activity level in both groups. Mean follow-up was of 15 months where eleven patients reported an excellent recovery, two patients had good recovery while one patient reported poor outcome. Mean AOFAS ankle hind foot scale improved from 50.5 preoperatively to 85.71 postoperatively (statistically significant; p value - 0.0001). Mean Likert scale value post-operative was 4.21. VAS score showed significant improvement in patients of both the groups. Range of motion was slightly better in soft tissue impingement type with a relatively shorter time to return to sports or preinjury activity level as compared to osseous impingement group. The patients in both the groups had comparable outcomes with no statistically significant difference with regard to patient satisfaction and clinical outcome.

The aim of this study is to evaluate and compare the treatment outcomes of the bilateral inguinal hernia repair in one stage using minimally invasive technique (totally extraperitoneal) and conventional surgery (Lichtenstein). Records from all hospitalized cases in our institution between 2006 and 2011 that underwent surgery having the diagnosis of bilateral inguinal hernia were analysed. The study consists of two groups selected by means of the used procedure: the study arm which is laparoscopic (234 cases) and the control arm that consists of Lichtenstein procedure (91 cases). One conversion was recorded due to difficult dissection (0.4% of cases). There were complications reported in 2.5% cases in the laparoscopic group and 27.4% complications noted in the conventional group (p less then 0.01). Reinterventions were logged in 1.7% cases in the laparoscopic group and 2.1% reinterventions in the open group (p less then 0.01). The postoperative hospital stay was 2.1 days in the laparoscopic group and 4.7 days for the open procedure. Mortality was not recorded. In our department the procedure of choice for bilateral inguinal repair is the laparoscopic approach (TEP) which has a 10 fold decrease in complications rate than Lichtenstein operation and also a shortening by half of the hospital stay. Hernia recurrence is the same for both procedures. Celsius.

To investigate the effect of Huangqi injection on the short-term prognosis in childhood with acute lymphoblastic leukemia (ALL). A retrospective analysis was performed on the clinical data of 105 children newly diagnosed with ALL between January 2009 and December 2012. These children were randomly divided into treatment group (18 low-risk cases, 7 medium-risk cases, and 24 high-risk cases) and control group (21 low-risk cases, 7 medium-risk cases, 28 high-risk cases). Both groups were given remission induction therapy based on the levels of risk. Throughout the remission induction therapy, the treatment group also received Huangqi injection (0.5-1.0 mL/kg per day) by intravenous infusion, while the control group was given 0.9% sodium chloride injection instead. The two groups were compared in terms of distribution of prognostic factors and complete remission (CR) rate after remission induction therapy, as well as the incidence of minimal residual disease (MDR) (≥ 10(-4) and < 10(-4)) among all patients in the two groups on day 19 of remission induction therapy and among B-ALL patients in the two groups when achieving a CR at the end of remission induction therapy. Of the 105 children with ALL, 99 had B-ALL, and 6 had T-ALL. There were no significant differences in the distribution of prognostic factors between the two groups (P>0.05). The overall CR rate of 105 patients was 79%; there was no significant difference in CR rate between the treatment and control groups (82% vs 77%; P>0.05); also, no significant differences were found between the two groups in the CR rates among high-, medium-, and low-risk cases (P>0.05). On day 19 of remission induction therapy, the incidence of MRD≥10(-4) in the treatment group was significantly lower than that in the control group (69% vs 95%; P<0.05); among 80 children with B-ALL who achieved a CR (43 cases in the control group and 37 cases in the treatment group), the incidence of MRD≥10-4 was significantly lower in the treatment group than in the control group (27% vs 58%; P<0.05); in both circumstances above, the high- and low-risk cases in the treatment group had a significantly lower incidence of MRD≥10(-4) than the control group (P<0.05). Huangqi injection combined with chemotherapy has an enhanced anti-tumor effect and can improve the short-term prognosis and clinical outcome in children with ALL.

To investigate the effect of joint mobilization on postoperative wrist joint function, pain and grip strength for elderly patients with distal radius fracture. From January 2015 to June 2016, a total of 67 elderly patients with distal radius fracture were randomly divided into routine exercise group and joint mobilization group. Among them, 37 patients in the routine exercise group underwent conventional distal radius fracture postoperative joint function exercise regimen, including 16 males and 21 females with a mean age of (67.8±3.2) years old ranging from 60 to 72 years old;the injured side was dominant in 23 cases and non-dominant in 14 cases;injury mechanism was fall in 26 cases, traffic accident in 11 cases; for AO type, 6 cases were type B3, 18 cases were type C1, 7 cases were type C2, 6 cases was type C3. Other 30 patients in the joint mobilization group underwent joint mobilization on the basis of the routine exercise group including 14 males and 16 females with a mean age of (67.1±4.0) years old ranging from 61 to 74 years old; the injured side was dominant in 21 cases and non-dominant in 9 cases;injury mechanism was fall in 25 cases, traffic accident in 5 cases;for AO type, 8 cases were type B3, 13 cases were type C1, 6 cases were type C2, 9 cases were type C3. The wrist joint activity, Gartland-Werley wrist joint function score, VAS pain score and grip strength were observed at 3 months afrer treatment. After 3 months' treatment, the VAS in the routine exercise group was higher than that of the joint mobilization group ( P <0.05). The grip strength of affected side in both groups were lower than that of contralateral side, but the average grip strength of affected side in joint mobilization group was higher than that in routine exercise group( P <0.05). In routine exercise group, the average angle of flexion, extension, radial deviation were significantly higher than those of joint mobilization group( P <0.05). But ulnar deviation angle in routine exercise group compared with joint mobilization group had no significant difference ( P >0.05). In the comparison of each item of Gartland-Werley, there was no significant difference between two groups in residual deformity and complication( P >0.05); the average score of subjective score, objective score and total score in routine exercise group were significantly higher than those of the joint mobilization group ( P <0.05). The wrist function Gartland-Werley score in routine exercise group after treatment was excellent in 21 cases, good in 10, 6 in fair, while in joint mobilization group, excellent in 23, good in 6, fair in 1( P <0.05). The application of joint mobilization in the treatment of elderly patients with distal radius fracture can improve the joint activity and obtain better wrist function after surgery.

The purpose of this study was to report Acanthamoeba encystment in Bowman's layer in Japanese cases of persistent Acanthamoeba keratitis (AK). Laser confocal microscopic images of the cornea were obtained in vivo from 18 consecutive eyes from 17 confirmed AK patients. Retrospectively, 14 cases treated over 4 months were categorized as a nonpersistent group and three cases that required prolonged therapy for more than 6 months were categorized as a persistent group. Clinical outcomes based on final best-corrected visual acuity were retrospectively analyzed, and selected confocal images were evaluated qualitatively for abnormal findings. The final best-corrected visual acuity was significantly lower (P < 0.01) for patients in the persistent group compared with that in the nonpersistent group. At the initial visit, in vivo confocal microscopy demonstrated Acanthamoeba cysts exclusively in the epithelial layer in both the nonpersistent group (80%) and the persistent group (100%). At a subsequent follow-up visit, numerous Acanthamoeba cysts were observed in the epithelial cell layer and in Bowman's layer in all patients with persistent AK, but Acanthamoeba cysts were undetectable in all cases with nonpersistent AK tested. Invasion of cysts into Bowman's layer was characteristically observed in patients with persistence of AK. This finding suggests that invasion of Acanthamoeba cysts into Bowman's layer may be a useful predictor for a persistent clinical course.

This study aimed to compare two methods of treatment of infertility with gonadotropin with laparoscopic ovarian electrocauterization in patients with clomiphene citrate-resistant polycystic ovary syndrome (PCOS). A number of 104 nulipara patients with polycystic ovary syndrome, who were resistant to clomiphene citrate were randomly assigned to two groups. One group received gonadotropin; after the bleeding withdrawal and from the third day of the cycle, the injection of human menopausal gonadotropin (HMG) was started with 10 mg medroxy progesterone. The patients were followed with serial trans-vaginal sonographies. When the diameter of follicles reached to 18 mm, human chorionic gonadotropin (HCG) was prescribed. The other group was treated with laparoscopic ovarian electrocauterization under general anesthesia. If after 3 cycles, the anovulation was established with progesterone measurement, the clomiphene citrate was prescribed. Gonadotropin was administered, if the lack of ovulation persisted. No significant difference was documented between the two groups in terms of the obesity indexes, duration of infertility, age, sonographic and laboratory findings. In the gonadotropin group, 37 cases (71%) of pregnancy occurred. The rate of pregnancy was the same in the other group consisting of 18 cases treated by electrocautery, 9 cases with cautery + clomiphene, and 10 cases with clomiphene + cautery + gonadotropin. In the group treated with gonadotropin, there were 1 triple and 4 twins pregnancies. In the group treated with ovarian electrocautery, one twin pregnancy was observed. In the group treated with gonadotropin, 2 cases of ovarian hyperstimulation syndrome, 1 case of ectopic pregnancy and 6 cases of miscarriage occurred; the corresponding figure in the ovarian electrocautery group consisted of 5 cases of miscarriage. Our findings suggest that ovarian electrocauterization is an appropriate method with good efficacy and low complication rate for infertility treatment of women with clomiphene citrate-resistant polycystic ovary syndrome.

Basaloid squamous cell carcinoma (BSC) of the esophagus is classified as an epithelial malignant tumor and is a rare variant of squamous cell carcinoma (SCC). Most previous reports have suggested that advanced BSC has a poorer prognosis than typical SCC because of its high biological malignancy, but the biological activity of superficial BSC remains unclear. Twenty cases of superficial BSC, which underwent surgical resection in Tokai University Hospital between January 2004 and December 2013, were analyzed retrospectively. Among these cases, 19 cases with a T1 depth of invasion (BSC group) were compared with 180 cases of SCC that were resected during the same period and were pathologically diagnosed as T1 (SCC group). The frequency of lymph node metastasis in the T1 BSC group was significantly lower (2 patients, 11%) than that in the SCC group (84 patients, 47%) (P = 0.005). The frequency of lymphatic invasion in the BSC group was also lower (9 patients, 47%) than that in the SCC group (131 patients, 73%) (P = 0.021). The pathological type of the metastatic lymph node was BSC in all the superficial BSC cases with lymph node metastasis. This study demonstrated that lymph node metastasis was less likely to occur in cases with superficial BSC than in cases with superficial SCC. © The Authors 2017.

The purpose of this study is to compare communication patterns in calls subjected to a malpractice claim with matched controls. In many countries, telephone advice nursing is patients' first contact with healthcare. Telenurses' assessment of callers' symptoms and needs are based on verbal communication only, and problems with over-triage and under-triage have been reported. A total sample of all reported medical errors (n=33) during the period 2003-2010 within Swedish Healthcare Direct was retrieved. Corresponding calls were thereafter identified and collected as sound files from the manager in charge at the respective call centres. For technical reasons, calls from four of the cases were not possible to retrieve. For the present study, matched control calls (n=26) based on the patient's age, gender and main symptom presented by the caller were collected. Male patients were in majority (n=16), and the most common reasons for calling were abdominal pain (n=10) and chest pain (n=5). There were statistically significant differences between the communication in the cases and controls: telenurses used fewer open-ended medical questions (p<0.001) in the cases compared to the control calls; callers provided telenurses with more medical information in the control calls compared to the cases (p=0.001); and telenurses used more facilitation and patient activation activities in the control calls (p=0.034), such as back-channel response (p=0.001), compared to the cases. The present study shows that telenurses in malpractice claimed calls used more closed-ended questioning compared to those in control calls, who used more open-ended questioning and back-channel response, which provided them with richer medical descriptions and more information from the caller. Hence, these communicative techniques are important in addition to solid medical and nursing competence and sound decision aid systems. Published by the BMJ Publishing Group Limited.

To compare the difference in the short-term and long-term efficacy on cervical spondylosis of neck type between warm needling therapy in the regions of both neck and lumbus and that only in the region of neck. Eighty-one patients of cervical spondylosis of neck type were randomized into group A (41 cases) and group B (40 cases), in which 2 cases dropped out. Finally, 40 cases in the group A and 39 cases in the group B accomplished the trial. In the group A, the warm needling therapy was applied to the acupoints in the region of neck and the lumbus. Fengchi (GB 20), Tianzhu (BL 10), Neck-Bailao (EX-HN 15), Wangu (GB 12), Tianyou (TE 16) and ashi (including the tender points and code-like masses on palpation) were selected in the region of neck. Dachangshu (BL 25), Qihaishu (BL 24) and Jiaji (EX-B 2) of L5 were selected in the region of lumbus. The warm needling was applied to Fengchi (GB 20), Tianzhu (BL 10), Dachangshu (BL 25). In the group B, the warm needling therapy was applied only to the acupoints in the neck, which were same as the group A. The treatment was given once every two days, three times a week in the two groups. Separately, before treatment, 1 week after treatment, at the end of 2-week treatment and at the end of 1 month follow-up, the score of neck pain questionnaire (NPQ), the score of range of motion (ROM) in the cervical region and the score of the cervical symptoms were recorded. The efficacy at the end of treatment and in the follow-up was evaluated. Compared with those before treatment, the scores at all the observation time points were significantly improved in the two groups after treatment (all P <0.05). In the follow-up, NPQ score, ROM score and the score of cervicalsymptoms were different significantly between the two groups (all P <0.05). The results in the group A were better than those in the group B. At the end of 2-week treatment, the total effective rate was 92.5% (37/40) in the group A and was 87.2% (34/39) in the group B ( P >0.05). In the follow-up, the total effective rate was 87.5% (35/40) in the group A, better than 64.1% (25/39) in the group B ( P <0.05). The treatment for both neck and lumbar regions with warm needling therapy and the treatment in the local area all achieve the short-term efficacy on cervical spondylosis of neck type. For the long-term efficacy, the treatment for both neck and lumbar regions achieves the better result as compared with the routine treatment in the region of neck.

To compare early and late results of open and endovascular management of popliteal artery aneurysm in a retrospective single-center matched case-control study Methods: From 1981 to 2015, 309 consecutive interventions for popliteal artery aneurysm were performed in our institution, in 59 cases with endovascular repair and in 250 cases with open repair. Endovascular repair was preferred in older asymptomatic patients, while open repair was offered more frequently to patients with a thrombosed popliteal artery aneurysm and a poor run-off status. A one-to-one coarsened exact matching on the basis of the baseline demographic, clinical, and anatomical covariates significantly different between the two treatment options was performed and two equivalent groups of 56 endovascular repairs and open repairs were generated. The two groups were compared in terms of perioperative results with χ 2 test and of follow-up outcomes with the Kaplan-Meier curves and log-rank test. There were no differences between the two groups in terms of perioperative outcomes. Median duration of follow-up was 38 months. Five-year survival rates were 94% in endovascular repair group and 89.5% in open repair group (p = 0.4, log-rank 0.6). Primary patency rates at 1, 3, and 5 years were 81%, 78%, and 72% in endovascular repair group and 82.5%, 80%, and 64% in open repair group (p = 0.8, log-rank 0.01). Freedom from reintervention at 5 years was 65.5% in endovascular repair group and 76% in open repair group (p = 0.2, log-rank 1.2). Secondary patency at 1, 3, and 5 years was 94%, 86%, and 74% in endovascular repair group, and 94%, 89%, and 71% in open repair group, respectively (p = 0.9, log-rank 0.01). The rates of limb preservation at 5 years were 94% in endovascular repair group and 86.4% in open repair group (p = 0.3, log-rank 0.8). Open repair and endovascular repair of popliteal artery aneurysms provided in this retrospective single-center experience similar perioperative and follow-up results in equivalent groups of patients.

To evaluate the influence of patellar replacement on total knee arthroplasty by comparing with non patellar replacement. Between September 2010 and November 2010, 63 patients (63 knees) with osteoarthritis who met the selection criteria and underwent total knee arthroplasty, were randomly divided into 2 groups: patellar replacement in 32 cases (replacement group), non patellar replacement in 31 cases (non patellar replacement group). There was no significant difference in gender, age, disease duration, osteoarthritis grading, the clinical and functional scores of American Knee Society Score (KSS), the patellar tilt angle, tibiofemoral angle, and patellar ligament ratio between 2 groups (P > 0.05), they were comparable. After 6 weeks, 3, 6, and 12 months of operation, clinical and imaging evaluation methods were used to assessment the effectiveness. Primary healing of incision was obtained in all patients of 2 groups. Deep venous thrombosis occurred in 6 cases of replacement group and in 8 cases of non patellar replacement group. All patients were followed up 12 months. The postoperative incidence of anterior knee pain in replacement group was significantly lower than that in non patellar replacement group (P < 0.05) at 3, 6, and 12 months after operation. No significant difference was found in the postoperative KSS clinical score between 2 groups at each time point (P > 0.05). The joint function score of the replacement group was significantly higher than that of the non patellar replacement group at the other time point (P < 0.05) except the score at 6 weeks and 3 months. Significant difference was found in the patella score between 2 groups at 12 months (P < 0.05), but no significant difference at the other time points (P > 0.05). X-ray film showed no patellar fracture and dislocation, or loosening and breakage of internal fixation. At 12 months after operation, the tibiofemoral angle, the patellar ligament ratio, and the patellar tilt angle showed no significant difference between 2 groups (P > 0.05). Patella replacement can improve knee function score and the patella score, and reduce the incidence of postoperative anterior knee pain.

To investigate the effect of axial stress stimulation on tibial and fibular open fractures healing after Taylor space stent fixation. The data of 45 cases with tibial and fibular open fractures treated by Taylor space stent fixation who meet the selection criteria between January 2015 and June 2016 were retrospectively analysed. The patients were divided into trial group (23 cases) and control group (22 cases) according to whether the axial stress stimulation was performed after operation. There was no significant difference in gender, age, affected side, cause of injury, type of fracture, and interval time from injury to operation between 2 groups ( P >0.05). The axial stress stimulation was performed in trial group after operation. The axial load sharing ratio was tested, and when the value was less than 10%, the external fixator was removed. The fracture healing time, full weight-bearing time, and external fixator removal time were recorded and compared. After 6 months of external fixator removal, the function of the limb was assessed by Johner-Wruhs criteria for evaluation of final effectiveness of treatment of tibial shaft fractures. There were 2 and 3 cases of needle foreign body reaction in trial group and control group, respectively, and healed after symptomatic anti allergic treatment. All the patients were followed up 8-12 months with an average of 10 months. All the fractures reached clinical healing, no complication such as delayed union, nonunion, or osteomyelitis occurred. The fracture healing time, full weight-bearing time, and external fixator removal time in trial group were significantly shorter than those in control group ( P <0.05). After 6 months of external fixator removal, the function of the limb was excellent in 13 cases, good in 6 cases, fair in 3 cases, and poor in 1 case in trial group, with an excellent and good rate of 82.6%; and was excellent in 5 cases, good in 10 cases, fair in 4 cases, and poor in 3 cases in control group, with an excellent and good rate of 68.2%, showing significant difference between 2 groups ( Z =-2.146, P =0.032). The axial stress stimulation of Taylor space stent fixation can promote the healing of tibial and fibular open fractures and promote local bone formation at fracture site.

To explore the clinical values of the combined detection of C-reactive protein (CRP) and D-dimer (D-D) for acute leukemia (AL) patients complicated with disseminated intravascular coagulation (DIC). Among 52 cases of AL, 20 cases of AL complicated with DIC were selected as AL+DIC group, 32 cases of AL were selected as AL group, 30 healthy volunteers were used as control group; the detected values of CRP and D-D in 3 groups were compared. The CRP and D-D levels in AL+DIC group were significantly higher than those in AL and control groups (P < 0.05); the CRP and D-D levels in AL group were significatly higher than those in control group (P < 0.05). The D-D level and complicated DIC rate in patients with CRP < 10 mg/L were significantly lower than those in patients with CRP 10-100 and >100 mg/L (P <0.05), while the D-D level and complicated DIC rate in patients with 10-100 mg/L were significantly lower than those in patients with CRP > 100 mg/L (P <0.05). After treatment of patients, the CRP and D-D levels in AL and AL+DIC groups were obviously reduced as compared with levels of these 2 groups before treatment (P <0.05); the CRP and D-D levels in AL+DIC after treatment were significantly higher than those in AL group (P <0.05). The combined detection of CRP and D-D possesses a higher reference value for diagnosis and differentiation of AL and AL complicated with DIC, thus also has an important role in evaluation of therapeutic efficacy of AL.

Measuring the level of serum lipase has been used for the clinical diagnosis of acute pancreatitis. Reports showed that the serum lipase level increased in patients of clinical renal failure. In this study, we aimed to measure the change of serum lipase levels in chronic kidney diseases and determine whether it could serve as a clinical laboratory index for clinical renal failure diagnosis. Materials: The OLYMPUS AU5400 automatic biochemical analyzer was used to determine the serum levels of lipase and creatinine. The study included 120 cases in the clinical renal failure group, 76 cases in the nephrotic syndrome group, 81 cases in the chronic nephritis group, and 80 healthy controls from our hospital volunteers in the same period. We then compared the lipase levels and conducted statistical analyses among these groups. The serum lipase levels were 15.3 U/L, 79.8 U/L, 45.1 U/L, and 51.0 U/L in the normal control, clinical renal failure, nephrotic syndrome, and chronic nephritis groups, respectively. The lipase levels in the groups with diseases were significantly different compared with that of the normal control group (p < 0.01). The lipase level of the clinical renal failure group was significantly higher than that of the nephrotic syndrome group and chronic nephritis group (p < 0.01). However, no statistically significant difference between the nephrotic syndrome and chronic nephritis group (p > 0.05) was observed. Moreover, an association of the serum lipase with disease progression was observed in the study. Serum lipase is an effective serological index which can reflect the clinical changes in the clinical renal failure and tends to increase through the progression of renal dysfunction.

In patients with unresectable gastric cancer and outlet obstruction syndrome, gastric partitioning gastrojejunostomy is an alternative, which could avoid the drawbacks of the standard techniques. Comparison of antroduodenal stent, conventional gastrojejunostomy and gastric partitioning gastrojejunostomy. A retrospective, cross-sectional study was conducted on patients with unresectable distal gastric cancer and gastric outlet obstruction, treated with the three different techniques over the last 12 years, comparing results based on oral tolerance and complications. An analysis was performed on the results using the Student-t test for independent variables. The 22 patients were divided in 3 groups: group I (6 cases) stent, group II (9 cases) conventional gastrojejunostomy, and group III (7 cases) gastric partitioning gastrojejunostomy, respectively. The stent allows a shorter "postoperative" stay and early onset of oral tolerance (P<0.05), however, the gastric partitioning gastrojejunostomy achieve normal diet at 15th day (P<0.05). The mortality rate was higher in the stent group (33%) compared with surgical techniques, with a morbidity of 4/6 (66.7%) in Group I, 6/9 (66.7%) Group II, and 3/7 (42%) Group III. Re-interventions: 2/6 Group I, 3/9 Group II, and 0/7 Group III. The median survival was superior in the gastric partitioning gastrojejunostomy, achieving an overall survival of 6.5 months. The gastric partitioning gastrojejunostomy for treatment of gastric outlet obstruction in unresectable advanced gastric cancer is a safe technique, allowing a more complete diet with lower morbidity and improved survival.

Theoretical knowledge, visual perception, and sensorimotor skills are key elements in ultrasound education. Classroom-based presentations are used routinely to teach theoretical knowledge, whereas visual perception and sensorimotor skills typically require hands-on training (HT). We aimed to compare the effect of classroom-based lectures versus a case-based e-learning (based on clinical cases only) on the hands-on performance of trainees during an emergency ultrasound course. This is a randomized, controlled, parallel-group study. Sixty-two medical students were randomized into two groups [group 1 (G1) and group 2 (G2)]. G1 (n=29) was subjected to a precourse e-learning, based on 14 short screencasts (each 5 min), an on-site discussion (60 min), and a standardized HT session on the day of the course. G2 (n=31) received classroom-based presentations on the day of the course before an identical HT session. Both groups completed a multiple-choice (MC) pretest (test A), a practical postcourse test (objective structured clinical exam), and MC tests directly after the HT (test B) and 1 day after the course (test C). The Mann-Whitney U-test was used for statistical analysis. G1 performed markedly better in test A (median 84.2, 25%; 75% percentile: 68.5; 92.2) compared with G2 (65.8; 53.8; 80.4), who had not participated in case-based e-learning (P=0.0009). No differences were found in the objective structured clinical exam, test B, and test C. e-learning exclusively based on clinical cases is an effective method of education in preparation for HT sessions and can reduce attendance time in ultrasound courses.

The objective of the study was to measure the copeptin levels in maternal serum and umbilical cord serum at cesarean section and vaginal delivery in normotensive pregnancy and pre-eclamptic women. This was a prospective study at Mansoura University Hospital, Egypt. Ninety cases were included. They were divided into six groups: (1) normal pregnancy near term, as a control group, (2) primiparas who had vaginal delivery, (3) primiparas who had vaginal delivery and mild preeclampsia, (4) elective repeat cesarean section, (5) intrapartum cesarean section for indications other than fetal distress, and (6) intrapartum cesarean section for fetal distress. Serum copeptin concentrations were quantified with an enzyme-linked immunosorbent assay (ELISA). Mean, standard deviation, and paired t-test were used to test for significant change in quantitative data. The vaginal delivery groups had higher levels of maternal serum copeptin than the elective cesarean section group (P<0.01). Higher maternal serum copeptin levels were found in cases with pre-eclampsia as compared with the normotensive cases. The maternal copeptin levels during intrapartum cesarean section were higher than that during elective repeat cesarean section. There was a significant correlation between maternal copeptin levels and the duration of the first stage. In the presence of fetal distress, umbilical cord serum copeptin levels were significantly higher than other groups. Vaginal delivery can be very painful and stressful, and is accompanied by a marked increase of maternal serum copeptin. Increased maternal levels of serum copeptin were found in cases with pre-eclampsia as compared with the normotensive cases, and it may be helpful in assessing the disease. Intrauterine fetal distress is a strong stimulus to the release of copeptin into the fetal circulation. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Objectives: To compare the safety and intraoperative difficulties of two capsulorhexis techniques for white intumescent cataract: Femtolaser-assisted capsulorhexis and manual capsulorhexis performed in 2-3 stages, with the Utrata forceps. Materials and methods: A prospective comparative study that included 28 eyes divided into 2 equal groups in which capsulorhexis was performed by using the 2 methods. In the first group, the capsulorhexis was executed by using LenSx Femtolaser. In the second group, an Utrata forceps was used to perform a manual 2-3 steps capsulorhexis as follows: a small 2-3 mm capsulorhexis was performed after the staining of the anterior capsule with Trypan Blue along with a good pressurization with viscoelastic substance. The liquefied cortex was aspirated, followed by the enlargement of the capsulorhexis. In some cases, the enlargement was made after IOL implantation. Results: In the Femtolaser group, the capsule was completely detached in 13 cases and only in one case, the capsule had a few bridges which detached easily, without endangering the capsulorhexis integrity. Its size was 4,9 mm in all cases. In the group in which capsulorhexis was performed with the Utrata forceps in 2-3 stages, this was complete, circular and relatively well centered in all cases, but the size varied between 4,5 and 5,5 mm. Conclusions: Femtosecond laser-assisted capsulorhexis was round, well centered and of a desired size of 4,9 mm. The manual capsulorhexis with the Utrata forceps depends on the surgeon's skill and experience and requires a good local anesthesia, the coloring of the anterior capsule with Tripan Blue, using a large quantity of cohesive viscoelastic substances and sometimes using micro incision forceps for helpful maneuvers. The size and centering of the capsulorhexis are not always identical with the intended ones.

To compare the effectiveness of open reduction and conservative treatment for pediatric mandibular condylar fractures and to provide the evidence for the selection of clinical therapy. The clinical data were retrospectively analyzed from 25 patients with the mandibular condylar fractures between January 1988 and December 2006. Of them, 8 patients (11 fractures) were treated with surgical treatment (surgical group) and 17 patients (22 fractures) with non-surgical treatment (non-surgical group). In surgical group, there were 6 males (9 fractures) and 2 females (2 fractures) with an age range of 8-13 years; fracture was caused by tumbling in 7 cases and by traffic accident in 1 with an interval of 1-6 days between injury and hospitalization; and 5 cases were identified as unilateral condylar fractures (3 complicated by mental fractures) and 3 cases as bilateral condylar fractures complicated by mental fractures. In non-surgical group, there were 12 males (15 fractures) and 5 females (7 fractures) with an age range of 3-12 years; fracture was caused by falling from height in 4 cases, by tumbling in 10, and by traffic accident in 3 with an interval of 1-25 days between injury and hospitalization; and 12 cases were identified as unilateral condylar fractures (3 complicated by mental fractures) and 5 cases as bilateral condylar fractures (1 complicated by mental fracture). Incision healed by first intention in surgical group, and 25 cases were followed up 1-6 years with an average of 3.5 years. At 12 months after treatment, no temporomandibular joint pain, eating disorder, or limited mandibular movement occurred in 2 groups. No significant difference was observed in opening mouth extent, protrusive and lateral movements between 2 groups at 6 and 12 months (P > 0.05). During centric occlusion, mental point located at the midline with symmetric face figure. Two patients in surgical group and 3 in non-surgical group had slight snap when opening their mouths. Mandible deviation was observed in 3 patients of 2 groups, respectively when gaping. The X-ray films showed healing of fracture and condylar remodeling at 3-6 months. Mandibular ramus were symmetric in cephalometry. Good effectiveness can be obtained by surgical or non-surgical treatment in pediatric mandibular condylar fractures. Considering the pediatric mandibular condyle having powerful healing and reconstructing potency and avoiding secondary injury on the temporomandibular joint from surgery, non-surgical treatment should be first selected for the pediatric mandibular condylar fractures in patients under 7 years.

Many individuals with chronic obstructive pulmonary disease (COPD) remain undiagnosed worldwide. Health-care organisations are implementing case-finding programmes without good evidence of which are the most effective and cost-effective approaches. We assessed the effectiveness and cost-effectiveness of two alternative approaches to targeted case finding for COPD compared with routine practice. In this cluster-randomised controlled trial, participating general practices in the West Midlands, UK, were randomly assigned (1:1), via a computer-generated block randomisation sequence, to either a targeted case-finding group or a routine care group. Eligible patients were ever-smokers aged 40-79 years without a previously recorded diagnosis of COPD. Patients in the targeted case-finding group were further randomly assigned (1:1) via their household to receive either a screening questionnaire at the general practitioner (GP) consultation (opportunistic) or a screening questionnaire at the GP consultation plus a mailed questionnaire (active). Respondents reporting relevant respiratory symptoms were invited for post-bronchodilator spirometry. Patients, clinicians, and investigators were not masked to allocation, but group allocation was concealed from the researchers who performed the spirometry assessments. Primary outcomes were the percentage of the eligible population diagnosed with COPD within 1 year (defined as post-bronchodilator forced expiratory volume in 1 s [FEV1] to forced vital capacity [FVC] ratio <0·7 in patients with symptoms or a new diagnosis on their GP record) and cost per new COPD diagnosis. Multiple logistic and Poisson regression were used to estimate effect sizes. Costs were obtained from the trial. This trial is registered with ISRCTN, number ISRCTN14930255. From Aug 10, 2012, to June 22, 2014, 74 818 eligible patients from 54 diverse general practices were randomly assigned and completed the trial. At 1 year, 1278 (4%) cases of COPD were newly detected in 32 789 eligible patients in the targeted case-finding group compared with 337 (1%) cases in 42 029 patients in the routine care group (adjusted odds ratio [OR] 7·45 [95% CI 4·80-11·55], p<0·0001). The percentage of newly detected COPD cases was higher in the active case-finding group (822 [5%] of 15 378) than in the opportunistic case-finding group (370 [2%] of 15 387; adjusted OR 2·34 [2·06-2·66], p<0·0001; adjusted risk difference 2·9 per 100 patients [95% CI 2·3-3·6], p<0·0001). Active case finding was more cost-effective than opportunistic case finding (£333 vs £376 per case detected, respectively). In this well established primary care system, routine practice identified few new cases of COPD. An active targeted approach to case finding including mailed screening questionnaires before spirometry is a cost-effective way to identify undiagnosed patients and has the potential to improve their health.

The population of gynaecological cancer survivors is growing, yet little is known about the effects of cancer and treatment on socioeconomic conditions well beyond the completion of therapy. The aim of this study was to investigate the socioeconomic conditions in long-term survivors of gynaecological cancer compared with a representative group of women from the general population. The study comprises women aged 32-75 residing in central part of Norway and who were treated as primary cases of gynaecological cancer at the University Hospital in Trondheim, Norway (n=160), and a control group from the general population (n=493). All analyses were done by chi(2) test and logistic regression. Gynaecological cancer survivors scored lower on a Socioeconomic Condition Index than the control group. They had on the average a complete remission period of 12 years. Compared with the control group, they were more often disabled (p<0.01) and had lower annual household income (p<0.01). No difference was detected between the groups in ability to pay bills. More cases than controls had experienced problems assigning personal insurance (p<0.03). Long-term gynaecological cancer survivors lived under poorer socioeconomic conditions, were more often disabled and had lower annual household income than the women in the control group, whereas no difference in ability to pay bills were found between the groups. In spite of poorer socioeconomic conditions, the gynaecological cancer survivors seem to adapt well to their financial situation.

To identify the socioeconomic and psychosocial impacts of clinical treatment decisions for advanced unilateral intraocular retinoblastoma. Retrospective observational case series. institutional study at Alexandria Main University Hospital. records of 66 unilateral retinoblastoma cases treated from May 2005 to May 2013 were retrospectively reviewed. Sixty cases were eligible (International Intraocular Retinoblastoma Classification [IIRC] group C, D or E). two treatment groups were compared: enucleation vs. salvage treatment. Salvage treatment eyes were further subdivided based on IIRC group. Six socioeconomic parameters (financial burden, financial impact, psychological, social, medical and tumor impacts) were scored. Parameter scores ranged from 0 to 3, for overall score range 0 (no adverse impact) to 18 (severe adverse impact). derived Socioeconomic scores were correlated with treatment and outcomes. The enucleation group (28 eyes) had a median overall Socioeconomic score of 4/18, significantly lower than the salvage treatment group (32 eyes), median score 11/18 (P<0.01). Socioeconomic score varied with IIRC group. Attempted eye salvage failed in 25 children, due to uncontrolled tumor (44%) and socioeconomic impact of cumulative therapies (56%). Treatment duration and Socioeconomic score were higher for the 5 children in the salvage treatment group who developed metastatic disease compared to those without metastasis (P<0.01). The socioeconomic and psychosocial impacts of attempted ocular salvage for unilateral intraocular retinoblastoma are severe, in comparison to primary enucleation. Primary enucleation is a good treatment for unilateral retinoblastoma. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

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.

The aim of this study is analysing the impact of the systematic versus occasional videoconferencing discussion of patients with two respiratory referral units along 6 years of time over the efficiency of the in-person outpatient clinics of a thoracic surgery service. Retrospective and comparative study of the evaluated patients through videoconferencing and in-person first visits during two equivalents periods of time: Group A (occasional discussion of cases) between 2008-2010 and Group B (weekly regular discussion) 2011-2013. Data were obtained from two prospective and electronic data bases. The number of cases discussed using e-consultation, in-person outpatient clinics evaluation and finally operated on under general anaesthesia in each period of time are presented. For efficiency criteria, the index: number of operated on cases/number of first visit outpatient clinic patients is created. Non-parametric Wilcoxon test is used for comparison. The mean number of patients evaluated at the outpatient clinics/year on group A was 563 versus 464 on group B. The median number of cases discussed using videoconferencing/year was 42 for group A versus 136 for group B. The mean number of operated cases/first visit at the outpatient clinics was 0.7 versus 0.87 in group B (P=.04). The systematic regular discussion of cases using videoconferencing has a positive impact on the efficacy of the outpatient clinics of a Thoracic Surgery Service measured in terms of operated cases/first outpatient clinics visit.

An enquiry into sudden infant death syndrome (SIDS) in 1987 furnished us with detailed epidemiological data for 281 cases that underwent a thorough post-mortem examination. This analysis uses these data to evaluate the role the autopsy plays in explaining sudden death. The cases were classified into three diagnostic groups: explained causes of death (group 1), unexplained deaths with anomalies (group 2), and no anomaly (group 3). These 281 cases show the three essential features that characterize SIDS: over-representation of males, increased deaths during the second and third months of life, and increased deaths during winter. The autopsy examination revealed that many of these deaths had a medical explanation. Almost half were assigned to group 1. At the time of autopsy, no precise pathology could be diagnosed for 147 deaths; of these, 140 showed histological anomalies. There were only seven sudden deaths for which no abnormal sign was evident at the autopsy. These results are compared with those of similar studies and discussed in connection with three factors: the initial selection of cases, the nature and degree of the investigations, and the possible interpretations of the symptoms uncovered.

Scabies is a common contagious skin disease in children. Treatment of scabies in infants and children is the subject of worldwide concern because of risk and benefit of the variety of scabicides. To compare the efficacy of 10 per cent sulfur ointment and 0.3 per cent gamma benzene hexachloride gel for the treatment of scabies in children. A randomized investigator blind study was conducted to compare the efficacy of 10 per cent sulfur ointment and 0.3 per cent gamma benzene hexachloride (GBH) for the treatment of scabies in children at Queen Sirikit National Institute of Child Health from December 1999 to May 2000. Diagnosis was made by the clinical signs of excoriated papules in the classic distribution with nocturnal pruritus and family history of similar symptoms. Diagnosis for all patients was confirmed by positive skin scrapings for eggs, larva, mites or fecal pellets by light microscopy. Patients were followed-up at intervals of 2 and 4 weeks. One hundred children with an age range from 6 months to 13 years were randomized into 2 groups, 10 per cent sulfur group (50 cases) and 0.3 per cent GBH (50 cases). Age, sex, history of contact cases and clinical manifestations were not statistically different between the two groups. After 4 weeks of treatment, there were no statistical differences between the two groups in patients assessed cured (92% vs 94%), clinical cure (92% vs 91%) and parasitic cure (83% vs 84%). The adverse effect of foul odor in the sulfur group was more common than in the GBH group (p < 0.05). 10 per cent sulfur ointment is as safe and efficacious as 0.3 per cent GBH for the treatment of scabies in children.

Candidiasis, the infection caused by Candida albicans , is one of the most common infections of the oral cavity in humans. Candidiasis causes irritation and is known for its carcinogenic effects. Thus, it is important to recognize the predisposing factors for this opportunistic infection. Several previous studies have demonstrated an increased frequency of vaginal candidiasis in relation to oral contraceptive consumption. Only a few studies on the relation between oral contraceptives and oral candidiasis have been previously conducted. This study aims to evaluate the possible relation between oral contraceptive pills and oral candidiasis. This analytic, case-control study included 40 non-pregnant women divided into two groups: 20 who used oral contraceptive pills and 20 who did not. The groups were matched according to age, oral health, and past and present medical history. Samples were collected from the tongue's dorsum using a cotton swab and inoculated on CHROMagar culture plates. The frequency of positive cultures and the number of Candida colonies were compared between the two groups using independent t-tests and Mann-Whitney statistical tests with SPSS18 software. The frequency of positive cultures of Candida albicans was higher (P value = 0.03) for the case group. Also, the number of C. albicans and C. krusei was significantly higher for the case group compared to the control group (P value = 0.04, P value = 0.03). The results of the present study demonstrate that oral contraceptives containing estradiol can lead to Candida colonization in the oral cavity. It is recommended that further studies comparing the influence of oral contraceptives on Candida's adherence to the epithelium is highly recommended.

Study Design: Retrospective cohort study. Objective: To compare perioperative characteristics of stand-alone cages and anterior cervical plates used for anterior cervical discectomy and fusion (ACDF). Methods: We reviewed 40 adult patients who received a stand-alone cage for elective ACDF and matched them with 40 patients who received an anterior cervical plate. We statistically compared operative time, length of stay, proportion of ambulatory cases, overall complications necessitating a trip to the ED, readmission, or reoperation related to index procedure. Results: There were 21 women and 19 men in the plate cohort with average ages of 53 years ± 12 and 20 women and 20 men in the stand-alone group with an average age of 52 years ± 11. With no statistical difference in total number, the plate group experienced 4 short-term (within 90 days of discharge) complications, including 3 patients who visited the emergency department for dysphagia and 1 who visited the emergency department for severe back pain, while the stand-alone group experienced 0 complications. There was no significant difference in operative time between the stand-alone group (75.35 min) and the plate group (81.35 min; P = .37). There was a significant difference between the proportion of ambulatory cases in the stand-alone group (25) and the plate group (6; P < .0001). Conclusion: Our results demonstrate that stand-alone cages have fewer complications compared to anterior plating, with a lower trend of incidence of postoperative dysphagia. Stand-alone cages may offer the advantage of sending patients home ambulatory after ACDF surgery. PMID:28811982

Despite the significant contribution of surgical spending to health care costs, most surgeons are unaware of their operating room costs. To examine the association between providing surgeons with individualized cost feedback and surgical supply costs in the operating room. The OR Surgical Cost Reduction (OR SCORE) project was a single-health system, multihospital, multidepartmental prospective controlled study in an urban academic setting. Intervention participants were attending surgeons in orthopedic surgery, otolaryngology-head and neck surgery, and neurological surgery (n = 63). Control participants were attending surgeons in cardiothoracic surgery, general surgery, vascular surgery, pediatric surgery, obstetrics/gynecology, ophthalmology, and urology (n = 186). From January 1 to December 31, 2015, each surgeon in the intervention group received standardized monthly scorecards showing the median surgical supply direct cost for each procedure type performed in the prior month compared with the surgeon's baseline (July 1, 2012, to November 30, 2014) and compared with all surgeons at the institution performing the same procedure at baseline. All surgical departments were eligible for a financial incentive if they met a 5% cost reduction goal. The primary outcome was each group's median surgical supply cost per case. Secondary outcome measures included total departmental surgical supply costs, case mix index-adjusted median surgical supply costs, patient outcomes (30-day readmission, 30-day mortality, and discharge status), and surgeon responses to a postintervention study-specific health care value survey. The median surgical supply direct costs per case decreased 6.54% in the intervention group, from $1398 (interquartile range [IQR], $316-$5181) (10 637 cases) in 2014 to $1307 (IQR, $319-$5037) (11 820 cases) in 2015. In contrast, the median surgical supply direct cost increased 7.42% in the control group, from $712 (IQR, $202-$1602) (16 441 cases) in 2014 to $765 (IQR, $233-$1719) (17 227 cases) in 2015. This decrease represents a total savings of $836 147 in the intervention group during the 1-year study. After controlling for surgeon, department, patient demographics, and clinical indicators in a mixed-effects model, there was a 9.95% (95% CI, 3.55%-15.93%; P = .003) surgical supply cost decrease in the intervention group over 1 year. Patient outcomes were equivalent or improved after the intervention, and surgeons who received scorecards reported higher levels of cost awareness on the health care value survey compared with controls. Cost feedback to surgeons, combined with a small departmental financial incentive, was associated with significantly reduced surgical supply costs, without negatively affecting patient outcomes.

Case management interventions for suicide attempters aimed at helping adjust their social life to prevent reattempts have high nonparticipation and dropout rates. We analyzed the clinical characteristics of the group who refused to participate in the suicide prevention program in Korea. A total of 489 patients with a suicide attempt who visited Uijeongbu St. Mary's Hospital, the Catholic University of Korea, from December 2009 to December 2013 were analyzed. All patients were divided into the participation group (n = 262) and the refusal group (n = 227) according to their participation in the case management program. Demographic and clinical characteristics of each group were examined. Results showed that the refusal group had low risks for suicide in terms of risk factors related with psychopathologies and presenting suicide behavior. That is, the refusal group had less patients with co-morbid medical illnesses and more patients with mild severity of depression compared to the participation group. However, the refusal group had more interpersonal conflict, more isolation of social integrity, and more impaired insight about suicide attempt. The results suggest that nonparticipation in the case management program may depend upon the patient's impaired insight about the riskiness of suicide and lack of social support.

The therapeutic efficacy of serial casting on idiopathic scoliosis has been gradually documented. However, literatures on serial casting for congenital scoliosis (CS) remain extremely rare. This paper aimed to compare the treatment outcomes of serial casting between CS and non-CS patients to comprehensively evaluate the therapeutic characteristics of serial casting on CS patients. A total of 23 early-onset scoliosis cases were included and divided into congenital scoliosis (CS, n = 8) and non-congenital group (non-CS, n = 15). Therapeutic outcomes including the major curve Cobb angle, thoracic kyphosis angle, lumbar lodosis angle, and thoracic spine growing rate were compared between groups at precast, after the first cast, and at the latest follow-up, respectively. All patients received the first cast at the age of 3.25 ± 1.20 years and 5.70 ± 1.18 times of cast corrections. The average casting time was 17.17 ± 3.38 months, and the mean follow-up time was 23.91 ± 12.28 months. Both CS and non-CS groups had significant decrease in Cobb angle after the first cast and at the latest follow-up (all P < 0.05). Cobb angle was significantly lower in non-CS group than in CS group at both time points (all P < 0.01). The correction rate of Cobb angle was significantly higher in non-CS group than in CS group (around 50 vs. 20%, both P < 0.01). The mean thoracic growth rate was significantly lower in CS group than in non-CS group (0.72 ± 0.20 vs. 1.42 ± 0.22 cm/year, P < 0.001). At the latest follow-up, there are 2 cases receiving growing rod surgery, 8 cases wearing a brace, and 13 cases continuing serial casting. Although the therapeutic efficacy of casting on CS patients is not as good as that on non-CS patients, casting is still an efficient treatment option for CS patients to delay the need for initial surgery.

The aim is to estimate the relative risk and population attributable risk (PAR) of risk factors for ischemic stroke by ethnic group. In this case-control study, cases of first ischemic stroke were taken from the South London Stroke Register and controls from a cross-sectional prevalence survey covering the same area. PAR was determined for each risk factor by ethnic group. Multivariable analysis was used to examine the association between risk factors and ischemic stroke across all ethnic groups. 664 cases and 716 controls aged 45 to 74 years were included, with ethnicity of white 78%:42%, black Caribbean 16%:43%, and black African 6%:15%, respectively. For the white group, high PAR was found for ischemic heart disease (IHD) on ECG (56% [95% CI, 49% to 62%]), obesity (49% [95% CI, 40% to 56%]), hypertension (HT) (38% [95% CI, 29% to 46%]), smoking (31% [95% CI, 19% to 41%]), transient ischemic attack (TIA) (23% [95% CI, 19% to 27%]), and atrial fibrillation (AF) (16% [95% CI, 10% to 21%]). In the black Caribbean compared with the white group, PAR was higher for HT (46% [95% CI, 21% to 63%]) and diabetes mellitus (DM) (29% [95% CI, 14% to 42%]), and lower for current smoking (18% [95% CI, 1% to 32%]) and AF (10% [95% CI, 0% to 18%]). In the black African group HT had a higher PAR (59% [95% CI, 91% to 82%]) than the other groups. PAR for AF (11% [95% CI, -11% to 29%]), obesity (30% [95% CI, -20% to 60%]), and DM (4% [95% CI, -25% to 26%]) was low compared with the other groups. In multivariable analysis, risk factors associated with ischemic stroke included TIA, AF, IHD on ECG, smoking, excess alcohol, obesity, HT, and DM. In the first European case-control study examining risk factors for ischemic stroke in black Caribbean and African populations, some differences were demonstrated in the impact of risk factors between these groups. It may be important to address such differences when developing stroke preventative strategies.

Some factors have an important role in endometriosis pathogenesis; there is an immune cell that plays an important role in endometrial cells that have reflux. Woman with endometriosis experienced the cellular immune disorder. It is suspected that decrease of NK cell in the peritoneal fluid caused by its qualitative defect with CD107a expression as the best marker. The aim of this study was to compare expression of NK Cell activity with CD107a between awoman with endometriosis and non-endometriosis. A case-control study from March until July 2015 in Haji Adam Malik General Hospital. The case group was ectopic endometrial tissue block paraffin and control group was normal endometrial tissue block paraffin. This study included 23 patients in endometriosis group and control group respectively. A majority proportion of CD107a expression in endometriosis group was +1 (16 patients (69.6%)), while the control group was +3 (9 patients (39.1%)). Expression of NK cell activity with CD107a in patients with endometriosis was lower than the control group (p<0.05). It suggested that cellular immune factors may play a role in the pathogenesis of endometriosis.

Placenta previa (PP) is a potential life-threatening pregnancy complication. Pro-brain natriuretic peptide (ProBNP), creatine kinase (CK), cardiac form of CK (CK-MB) and Troponin I are circulatory biomarkers related to cardiac functions. We aimed to determine whether these biomarkers are related to PP and placenta accreta. In this case-control study, fifty-four pregnant women who attended our tertiary care center for perinatology with the diagnosis of PP totalis, and of them, 14 patients with placenta accreta were recruited as the study groups. Forty-six uncomplicated control patients who were matched for age, BMI were also included. Maternal venous ProBNP, CK, CK-MB and Troponin I levels were compared between the three groups. Obstetric history characteristics were comparable among groups, generally. CK and CK-MB levels were similar among three groups. Troponin I levels in the previa and accreta groups were significantly higher than the controls. ProBNP levels in the accreta group were significantly higher than other two groups. The multivariate regression model revealed that ProBNP could predict placental adhesion anomalies. Troponin I and ProBNP levels in PP cases were higher than controls and ProBNP could predict placenta accreta.

Type 2 diabetes mellitus (T2DM) is a consequence of complex interactions among multiple genetic variants and environmental risk factors. This complex disorder is also characterized by changes in various adipokines. In this study, our objective was to estimate the levels of adiponectin, leptin, and resistin (ALR) in T2DM patients, besides studying the effect of various drugs on their levels. Study participants included 400 diabetic and 300 normal patients from the Department of Endocrinology and Department of Biochemistry, Govt Medical College Srinagar. Subjects were categorized under various groups, i.e., Group 1 (metformin treated) and Group 2 (glimepiride treated), and cases were also categorized as obese with T2DM (Group A), obese without T2DM (Group B), and T2DM only (Group C). The serum ALR levels were estimated by ELISA (Alere), and biochemical parameters were also evaluated before and after treatment. Adiponectin levels were found to be significantly lower in T2DM cases as compared to controls (12 ± 5.5 versus 22.5 ± 7.9 μg/ml), while leptin and resistin levels were found to be significantly higher than controls (14.3 ± 7.4 versus 7.36 ± 3.73 ng/ml) (13.4 ± 1.56 versus 7.236 ± 2.129 pg/ml). Taking the effect of drugs into consideration, the effect on adiponectin and resistin levels was found to be highly significant in Group 2 before and after treatment (11 ± 5 versus 19.2 ± 4.5 μg/ml) (13.6 ± 2.5 versus 7.3 ± 2.9 pg/ml), while more effect was observed in leptin among Group 1 (metformin)-treated cases (27 ± 15 ng/ml versus 15 ± 15 ng/ml). Further the adiponectin levels were found to be significantly lower in Group B, while leptin and resistin levels were found to be significantly higher among obese cases when compared to T2DM cases only. Glimepiride also shows more effect on FBG, HbA1c% levels, while metformin shows more effect on Lipid profile levels. From the study, it can be concluded that ALR levels are affected by use of antidiabetic drugs among which glimepiride shows more effect on adiponectin and resistin levels, while leptin gets affected more by metformin. It can also be proposed that ALR levels are not affected by diabetes only, suggesting that their alterations in T2DM may be due to obesity as we observed more ALR changes in obese cases when compared to T2DM cases, and so there might be an important link between adiposity and insulin resistance.

To compare the therapeutic effect of acupuncture for gastrointestinal neurosis with that of oral remedy. Eighty cases were randomly divided into the following 2 groups. In the treatment group, acupuncture was given for one month at the main points of Zhongwan (CV 12), Zusanli (ST 36), Taichong (LR 3) and Shenmen (HT 7), with the auxiliary points selected according to TCM differentiation. In the control group, Domperidone was orally administered for one month. The total effective rate was 92.5% in the treatment group and 75.0% in the control group, with a significant difference between the 2 groups (chi2 = 4.423, P < 0.05). Acupuncture was superior to the oral remedy in therapeutic effects. Acupuncture may show better results for gastrointestinal neurosis and with less toxic side effects.

To compare the clinical efficacy on cervical spondylotic radiculopathy between the combined therapy of massage and magnetic-sticking at the auricular points and the simple massage therapy, and conduct the health economics evaluation. Seventy-two patients of cervical spondylotic radiculopathy were randomized into a combined therapy group, and a simple massage group, 36 cases in each one. Finally, 35 cases and 34 cases were met the inclusive criteria in the corresponding groups separately. In the combined therapy group, the massage therapy and the magnetic sticking therapy at auricular points were combined in the treatment. Massage therapy was mainly applied to Fengchi (GB 20), Jianjing (GB 21), Jianwaishu (SI 14), Jianyu (LI 15) and Quchi (LI 11). The main auricular points for magnetic sticking pressure were Jingzhui (AH13), Gan (On12) Shen (CO10), Shenmen (TF4), Pizhixia (AT4). In the simple massage group, the simple massage therapy was given, the massage parts and methods were the same as those in the combined therapy group. The treatment was given once every two days, three times a week, for 4 weeks totally. The cervical spondylosis effect scale and the simplified McGill pain questionnaire were adopted to observe the improvements in the clinical symptoms, clinical examination, daily life movement, superficial muscular pain in the neck and the health economics cost in the patients of the two groups. The effect was evaluated in the two groups. The effective rate and the clinical curative rate in the combined therapy group were better than those in the control group [100. 0% (35/35) vs 85. 3% (29/34), 42. 9% (15/35) vs 17. 6% (6/34), both P<0. 05]. The scores of the spontaneous symptoms, clinical examnation, daily life movement and superficialmuscular pain in the neck were improved apparently after treatment as compared with those before treatment in the patients of the two groups (all P<0. 001). In terms of the improvements in the spontaneous symptoms, clinical examination total scores and superficial muscular pain in the' neck were more significant in the combined therapy group as compared with those in the simple massage group (P<0. 05, P<0. 01, P<0. 001). The cost at the unit effect in the combined therapy group was lower than that in the simple massage group (P<0. 05). Compared with the simple massage therapy, the massage therapy combined with magnetic sticking therapy at auricular points achieves the better effect and lower cost in health economics.

We examined the association of ABO blood groups with the different types of head and neck cancers. 195 diagnosed cases and 801 controls were selected from a Greek tertiary cancer center. Information regarding type of head and neck cancer and ABO blood group was collected and registered. The O blood group was found to be most prevalent followed by A, B and AB among the controls, whereas blood group A followed by O, B and AB was most prevalent among cancer patients. The difference among the distribution between the cases and controls was statistically significant in blood group A (p<0.05), whereas blood group A had 1.52-fold higher risk of developing head and neck cancer compared to people of other blood groups. Blood group A was found to be a potential risk factor for the development of head and neck cancers.

The aim of this study was to evaluate the efficacy of the Thopaz system, a new drainage system in management of general thoracic surgery, based on a review of our clinical practice and a comparison of the utility of the Thopaz device compared with a standard drainage system. A review of 540 thoracic surgeries at our hospital was performed. These cases were divided into 275 treated with the Thopaz system from April 2014 to March 2015 and 265 treated with a standard system from April 2013 to March 2014. The characteristics of patients and outcomes after surgery were compared in these 2 groups. The characteristics of the patients were similar in the 2 groups. Outcomes after surgery, including types of operation, period of chest tube placement, chest tube reinsertion rate and clamping test rate also did not differ significantly between the groups. The non-inferiority of the Thopaz system compared to a standard system was verified statistically. With advantages of providing objective data as a small portable system, in addition to the quietness of the unit and the ease of setup and operation, Thopaz system is likely to become mainstream in postoperative management in general thoracic surgery. © 2017 John Wiley & Sons Ltd.

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 of the present study was to investigate the correlation between Klotho gene polymorphisms andcalcium oxalate stones in Xinjiang Uyghur people. We compared 128 patients with calcium oxalate stones (case group) and 94 healthypeople (control group), detected the genotype and allele distributions of single-nucleotide polymorphisms (SNPs)of the Klotho gene (rs3752472, rs650439, and rs1207568) by reverse transcription polymerase chain reaction. The distributions of the genotype and allele frequencies of the SNPs were consistent with the Hardy-Weinberg equilibrium in the two groups. There were statistically significant differences between the genotype andallele distributions of rs3752472 between the case and control groups; the allele frequencies in the case/controlgroups were C = 240 (93.7%)/151 (80.3%) and T = 16 (6.3%)/37 (19.7%). There was no statistically significantdifference in the genotype distribution of rs650439 between the case and control groups, but there was a differencein the allele distribution; the allele frequencies in the case/control groups were A = 202 (78.9%)/143 (57.2%) andT = 54 (21.1%)/107 (42.8%). There were no statistically significant differences in genotype and allele distributionsbetween the case and control groups of rs1207568; the allele frequencies in the case/control groups were C = 194(71.3%)/145 (77.1%) and T = 78 (28.7%)/43 (22.9%). In rs3752472, the risk for patients with the C and A allelesincreased by 3.675 and 2.799 times, respectively. The rs3752472 and rs650439 SNPs are related to the risk of calcium oxalate stones in Xinjiang Uyghurpeople, and might be one of the risk factors.

Information on serum albumin and trace elements among children suffering from Sickle Cell Anemia (SCA) was poorly documented in Africa. The aim of this study was to describe and to compare different values of trace elements with published reports from other parts of the world. We carried out a case-control study. Seventy-six steady state children suffering from SCA (Hb-SS). One hundred and fifty-two children were recruited with 76 (cases, Hb-SS) and 76 (control, Hb-AA) to compare the data. The mean age was 10.0 years (SD=5.4) in SCA children and 9.2 years (SD=4.7) in the control group. The mean level of zinc and magnesium were slightly lower in the Hb-SS group than in the Hb-AA group (P<.001). The first literature about trace elements in SCA is briefly reported in Central Africa. In our midst, zinc, magnesium, and selenium deficiencies underline the need for their systematic among all children with SCA to identify patients with these deficiencies and provide early management. © 2017 Wiley Periodicals, Inc.

To investigate surgical outcomes and complications of scoliosis associated with Marfan syndrome. Inclusion criteria were patients who were 10-20 years of age, had a diagnosis of Marfan syndrome by the Ghent nosology, had scoliosis and had undergone spinal fusion, and had at least 2 years of postoperative follow-up. The medical records of all patients were reviewed for age at the time of surgery, surgical procedures performed, instrumentation type, estimated blood loss (EBL) during surgery, operation time and complications related to surgery. Health-related quality-of-life measures (obtained with the SRS-22 Questionnaire before operation and at the last clinical follow-up) were also recorded. Patients were analyzed as two different groups, Group 1 and Group 2, according to the different approaches employed. Patients receiving combined anterior and posterior surgery were assigned to Group 1 and those who received posterior-only surgery to Group 2. Group 1 consisted of 30 patients (14 males, 16 females) with a mean age at surgery of 16.8 years (range: 10-20 years). Complications in Group 1 included two cases of instrumentation loosening with one removed, one case of instrumentation breakage and one case of chylothorax and hemothorax during video assisted thoracoscopic release. 66 patients (28 males, 38 females) with a mean age at surgery of years 16.4 years (range: 10-20 years) were included in Group 2. Complications in Group 2 included six cases of cerebro-spinal fluid leak, one case of deep wound infection secondary to cerebro-spinal fluid leak, one case of leg weakness and one case of pleural rupture cause by misplacement of pedicle screw. There is no difference of age at surgery, preoperative Cobb angles, and SRS-22 total scores (3.0 vs. 3.1) between the two groups (P > 0.05). Group 1 yielded larger correction rate than Group 2 for both thoracic (62.5 % vs. 56.2 %) and lumbar scoliosis (68.3 % vs. 62.7 %). Loss of correction was similar between the two groups for both thoracic (4.1° vs. 3.6°) and lumbar (4.2° vs. 4.6°) curves (P > 0.05). EBL (1972 ml vs. 1530) and operation time (669 min vs. 419 min) were significantly increased in Group 1 than in Group 2 (P < 0.05). No difference was noted for SRS-22 total scores in the last follow-up between the two groups (3.7 vs. 3.8, P > 0.05). In conclusion, as compared to anterior release combined with posterior spinal fusion, posterior-only spinal fusion could yield comparable clinical outcomes for scoliosis associated with Marfan syndrome with lower EBL, and operation time. However, longer follow-up is needed to verify these findings.

Background and Aim. Although many epidemiologic studies have shown that Helicobacter pylori eradication has prophylactic effects on gastric cancer, it does not completely eliminate the risk of gastric cancer. We aimed to investigate the changes in histological gastritis in patients receiving rebamipide treatment after H. pylori eradication. Methods. 206 patients who had undergone H. pylori eradication were evaluated. Of these, 169 patients who achieved successful eradication were randomly allocated to 2 groups: the rebamipide group (n = 82) and the untreated group (n = 87). The primary endpoints were histopathological findings according to the updated Sydney system at the start of the study and after 1 year. Results. Final assessment for histological gastritis was possible in 50 cases from the rebamipide group and 53 cases from the untreated group. The activity and atrophy improved in both the rebamipide and untreated groups, and no significant intergroup differences were observed. Chronic inflammation affecting the lesser curvature of the corpus was significantly improved in the rebamipide group compared to in the untreated group (1.12 ± 0.08 versus 1.35 ± 0.08; P = 0.043). Conclusions. Rebamipide treatment after H. pylori eradication alleviated chronic inflammation in the lesser curvature of the corpus compared to that in the untreated group. This trial is registered with UMIN000002369.

To investigate the effect of Huanshuai Recipe Oral Liquid ([characters: see text], HSR) on retarding the progression of renal dysfunction in patients with atherosclerotic renal artery stenosis (ARAS). A total of 52 ARAS patients with the Chinese medicine (CM) syndrome of qi deficiency and blood stasis, phlegm and dampness retention were recruited and randomly assigned into the treatment group (36 cases) and the control group (16 cases). Both groups received a basic treatment (high-quality low-protein diet, blood pressure control, lipid-lowering, correcting the acidosis, etc.). In addition, the treatment group received 20 mL HSR and the control group received placebo, 3 times a day for 6 months. Renal function (serum creatinine, blood urea nitrogen and uric acid) and blood lipids (cholesterol, triglycerides and low density lipoprotein) were examined monthly. The estimated glomerular filtration rate (eGFR) and CM syndrome score were compared between groups. After treatment, compared with the control group, the serum creatinine level, uric acid level and CM syndrome score of the treatment group were significantly decreased (P<0.05 or P<0.01), and the eGFR in the treatment group were significantly increased (P<0.05). HSR can effectively improve the renal function and clinical symptoms of ARAS patients.

2015-01-01

Proper seat belt use saves lives; however, the use rate decreased in Korea. This study aimed to measure the magnitude of the preventive effect of seat belt on case-fatality across drivers and passengers. We used the Emergency Department based Injury In-depth Surveillance (EDIIS) database from 17 EDs between 2011 and 2012. All of adult injured patients from road traffic injuries (RTI) in-vehicle of less than 10-seat van were eligible, excluding cases with unknown seat belt use and outcomes. Primary and secondary endpoints were in-hospital mortality and intracranial injury. We calculated adjusted odds ratios (AORs) of seat belt use and driving status for study outcomes adjusting for potential confounders. Among 23,698 eligible patients, 15,304 (64.6%) wore seat belts. Driver, middle aged (30-44 yr), male, daytime injured patients were more likely to use seat belts (all P < 0.001). In terms of clinical outcome, no seat belt group had higher proportions of case-fatality and intracranial injury compared to seat belt group (both P < 0.001). Compared to seat belt group, AORs (95% CIs) of no seat belt group were 10.43 (7.75-14.04) for case-fatality and 2.68 (2.25-3.19) for intracranial injury respectively. In the interaction model, AORs (95% CIs) of no seat belt use for case-fatality were 11.71 (8.45-16.22) in drivers and 5.52 (2.83-14.76) in non-driving passengers, respectively. Wearing seat belt has significantly preventive effects on case-fatality and intracranial injury. Public health efforts to increase seat belt use are needed to reduce health burden from RTIs.

When cases of dental crowding are identified and diagnosed promptly, interceptive orthodontics is particularly successful. Aim: To assess the differences in the eruption sequence of the mandibular canine and first premolar teeth in children with and without dental crowding. Materials and Methods: Children who attended the Shiraz Dental School's orthodontic clinic (Iran) from September to December 2012 were enrolled in this case-control study. Tooth size arch length discrepancy (TSALD) of all 8-10 year olds was calculated from patients’ dental models. Thirty-six children were randomly selected from those with TSALD of equal or less than 4mm (those with crowding). Each selected case was matched for sex and age with another child (as control) with TSALD>−4mm attending the same clinic, in the same time period. The existing panoramic radiographs were traced and the eruption percentages were measured for mandibular canine and first premolar teeth. The mean difference between canine and first premolar eruption percentages was compared between the case and control groups using the SPSS (version PASW 18) software and a paired sample t-test. Results: Canine and first premolar eruption percentages in the case group were 65.82±13.00 and 78.92±10.15 percent, respectively. The mean eruption percentages for canines and first premolars of the control group were 74.12±14.55 and 75.47±11.60 percent, respectively. There was a significant difference in pre-eruptive positions of canine and first premolar teeth in those with moderate to severe crowding when compared to the control group (p<0.001). Conclusion: These findings may improve the early diagnosis of children with high risk of developing moderate to severe crowding during mixed dentition. PMID:25110582

Cognitive and functional geriatric assessment may change in acromegaly. Herein we aimed to determine at which points geriatric assessment of the cases with acromegaly differs from that of general elderly population. In this comparative cross-sectional study, a total of 30 cases with acromegaly (controlled n = 14, uncontrolled n = 16) and 30 gender and body-mass index-matched cases without acromegaly (control group, CG) above 60 years old were included. Cognitive functions were evaluated on the basis of the mini-mental state exam (MMSE). Affective status was determined using the geriatric depression scale. Activities of daily living (ADL) were ranked according to the Barthel index while instrumental activities of daily living (IADL) were graded on the basis of the Lawton scale. Nutritional status was evaluated using the mini-nutritional assessment (MNA). Body composition was measured through bioimpedance analysis. Functional mobility was determined using the Timed Up and Go test (TUG) and muscle strength with the handgrip strength test. Scores on the MMSE were significantly lower in the elderly cases with acromegaly than in the cases without acromegaly (p < 0.001). Dementia was more frequent in the acromegaly group than in the CG (p = 0.04). Total MNA scores were significantly lower in cases with acromegaly than in the CG (p = 0.006). More subjects in the acromegaly group (33%) were at greater risk of malnutrition than in the CG (3%) (p = 0.003). There was greater moderate functional impairment based on Barthel ADL in the acromegaly group than in the CG (p = 0.04). Acromegaly may impair cognitive functions, functional mobility and instrumental daily living activities in the geriatric population. With acromegaly, the risk of malnutrition may also increase.

It is a common educational practice for medical students to engage in case-based learning (CBL) exercises by working through clinical cases that have been developed by faculty. While such faculty-developed exercises have educational strengths, there are at least two major drawbacks to learning by this method: the number and diversity of cases is often limited; and students decrease their engagement with CBL cases as they grow accustomed to the teaching method. We sought to explore whether student case creation can address both of these limitations. We also compared student case creation to traditional clinical reasoning sessions in regard to tutorial group effectiveness, perceived gains in clinical reasoning, and quality of student-faculty interaction. Ten first-year medical students participated in a feasibility study wherein they worked in small groups to develop their own patient case around a preassigned diagnosis. Faculty provided feedback on case quality afterwards. Students completed pre- and post-self-assessment surveys. Students and faculty also participated in separate focus groups to compare their case creation experience to traditional CBL sessions. Students reported high levels of team engagement and peer learning, as well as increased ownership over case content and understanding of clinical reasoning nuances. However, students also reported decreases in student-faculty interaction and the use of visual aids ( P < 0.05). The results of our feasibility study suggest that student-generated cases can be a valuable adjunct to traditional clinical reasoning instruction by increasing content ownership, encouraging student-directed learning, and providing opportunities to explore clinical nuances. However, these gains may reduce student-faculty interaction. Future studies may be able to identify an improved model of faculty participation, the ideal timing for incorporation of this method in a medical curriculum, and a more rigorous assessment of the impact of student case creation on the development of clinical reasoning skills.

In the previous studies, it has been shown that mumps-measles-rubella (MMR) vaccine resulted in regression of warts via immunomodulatory effect and induction of immune system. Due to the high prevalence of warts in various populations, we evaluated the efficacy of MMR vaccine injection in the treatment of cutaneous warts. This double-blind randomized controlled clinical trial was conducted in Hazrat-e-Rasoul Hospital in Tehran in 2011-2012 on 24 patients with warts who were allocated to two groups including MMR group and normal saline group. MMR vaccine was injected intralesionally in the MMR group, whereas normal saline was injected into the lesions in the second group. These injections were repeated every 2 weeks intervals for maximum 3 injections. All patients were followed up every 15-day interval up to 45 days and then up to 6 months regarding relapses and finally, side effects, probable relapse, and therapeutic outcomes were evaluated and compared. At the end of follow-up period, therapeutic outcomes in the MMR group included no cure in 2 cases, relative cure in 4 cases, and complete cure in 18 cases. In normal saline group, these rates included no cure in seven cases, relative cure in nine cases, and complete cure in six cases (P < 0.001). No significant complication occurred in the two groups. MMR vaccine may result in desirable therapeutic response. The hypothesis that is considered here is that MMR vaccine, via induction of cellular and humoral immune system, accelerates the destruction of virus and infected host cells.

AIM To evaluate the effect of nonsurgical periodontal therapy on glycosylated haemoglobin levels in pre-diabetic patients with chronic periodontitis (CHP). METHODS Sixty pre-diabetic patients with CHP were selected and equally allocated to case and control group. All subjects were evaluated at base line for periodontal parameters (plaque index, oral hygiene index, modified gingival index, probing pocket depth, clinical attachment level) and systemic parameters [glycosylated hemoglobin (HbA1c), fasting lipid profile, and fasting blood glucose]. The case group received non-surgical periodontal therapy. Subjects were re-evaluated for periodontal and systemic parameters after three months. RESULTS Both groups were comparable at baseline. Three months after non surgical periodontal therapy (NSPT), there was significant improvement in periodontal parameters in case group. The mean difference in systemic parameters like HbA1c and fasting plasma glucose from baseline to fourth month for case group was 0.22 ± 0.11 and 3.90 ± 8.48 respectively and control group was -0.056 ± 0.10 and -1.66 ± 6.04 respectively, which was significant between case and control group (P < 0.05). In the case group there was a significant decrease in HbA1c from baseline to three months following NSPT (P < 0.05). CONCLUSION This study showed that periodontal inflammation could affect the glycemic control in otherwise systemically healthy individuals. Periodontal therapy improved periodontal health status and decreased glycosylated haemoglobin levels, thus reducing the probability of occurrence of inflammation induced prediabetes in patients with CHP.

Congenital hypothyroidism (CH) is caused by thyroid dysgenesis and dyshormonogenesis. Evidence suggests the presence of genetic factors in both types of pathogenesis. We investigated whether an increased incidence of thyroid abnormalities could be shown by ultrasonography among first-degree relatives of children with CH. In this case-control study the presence of both developmental and non-developmental thyroid abnormalities was studied among first-degree relatives of CH patients and healthy children. Assessments included neck ultrasonography and thyroid function tests. The data obtained from parents, siblings and children were compared in the case and control groups. In the case group, 92 patients, 172 parents and 57 siblings, and in the control group, 82 healthy children, 160 parents and 39 siblings were studied. Thyroid developmental abnormalities were more prevalent among parents (3.5 vs. 0%, p = 0.03) and siblings (10.5 vs. 0, p = 0.01) of CH patients than the control group. Non-developmental abnormalities were not significantly different between the case and control groups (17 vs. 13%, p = 0.3). Thyroid developmental abnormalities were more prevalent among parents and siblings of CH patients than the control group, confirming the familial component of this entity. Copyright 2008 S.

To summarize the complications and the early clinical effect of less invasive stabilization system and the femoral condylar support plates in the treatment of AO type C distal femoral fractures. From September 2007 to February 2012, 46 patients with AO type C distal femoral fractures were retrospectively studied. Of all patients 25 were treated with less invasive stabilization system including 14 males and 11 females with a mean age of (56.3±4.2) years old; according to AO classification, there were 14 cases of C1, 8 cases of C2 and 3 cases of C3 with a mean hospital stay of (15.6±1.7) days. While 21 cases were treated with femoral condylar support plates fixation including 12 males and 9 females with a mean age of (53.8±5.1) years old;there were 13 cases of C1, 6 cases of C2 and 2 cases of C3 with a mean hospital stay of (17.8±2.2) days. Comparative analysis was performed from the operation related index,postoperative complications and Evanich score of the knee joint function between the two groups at follow-up. All 46 patients were followed up from 13 to 38 months with a mean time of 19.6 months after surgery. Complications included 1 case with infection,3 cases with internal fixation failure, 1 case with nonunion and 1 case with activity limitation of the affected knee. The differences in the incision length, blood loss, fracture healing time were significant between two groups (P<0.05), while there was no significant difference in the duration of operations, hospital stays and the incidence of postoperative complications between two groups (P>0.05). The statistical significance was also found in the Evanich score at last follow-up between two groups (P<0.05). Patients with less invasive stabilization system fixation had the characteristics of less trauma, shorter fracture healing time and better functional recovery. Less invasive stabilization system had became one of the ideal internal fixations in the treatment of AO type C distal femoral fractures.

To examine the effect of home-based exercise on knee osteoarthritis among Japanese in comparison with that of nonsteroidal antiinflammatory drugs (NSAIDs). An open-labeled, randomized, controlled, multiclinic trial compared home-based quadriceps exercise with NSAIDs. Treatments were basically evaluated after 8 wks and compared with the baseline scores. Outcomes were evaluated with a set of psychometric measurements including the Western Ontario and McMaster Universities Arthritis Index (WOMAC), 36-Item Short-Form Health Survey (SF-36), Japanese Knee Osteoarthritis Measure (JKOM), and pain with the visual analog scale. A total of 142 patients entered this trial to provide the baseline data. After 21 cases withdrew, the final number analyzed was 121 cases: 63 for the exercise group and 58 for the NSAIDs group. Between these two groups, there was no significant difference in gender, age, body height and weight, body mass index, or each score at baseline. The subjects in both groups showed improvements in all scores at the end of intervention. The difference in improvement rate of each score between the two groups was not statistically significant, though the mean rank score measured with JKOM in the exercise was slightly better than that of the NSAIDs. Home-based exercise using quadriceps strengthening improves knee osteoarthritis no less than NSAIDs.

Objectives Agriculture has undergone major changes, and farmers have been found to have a high prevalence of depression symptoms. We investigated the risk of work disability in Norwegian farmers compared with other occupational groups, as well as the associations between symptoms of anxiety and depression and future disability pension. Methods We linked working participants of the HUNT2 Survey (1995–97) aged 20–61.9 years, of whom 3495 were farmers and 25 521 had other occupations, to national registry data on disability pension, with follow-up until 31 December 2010. We used Cox proportional hazards regression to estimate hazard ratios (HRs) of disability pension, and to investigate the associations between symptoms of anxiety and depression caseness at baseline (score on the anxiety or depression subscales of the Hospital Anxiety and Depression Scale (HADS) ≥8) and disability pension. Results Farmers had a twofold increased risk of disability pension (age-adjusted and sex-adjusted HR 2.07, 95% CI 1.80 to 2.38) compared with higher grade professionals. Farmers with symptoms of depression caseness had a 53% increased risk of disability pension (HR 1.53, 95% CI 1.25 to 1.87) compared with farmers below the cut-off point of depression caseness symptoms, whereas farmers with symptoms of anxiety caseness had a 51% increased risk (HR 1.51, 95% CI 1.23 to 1.86). Conclusions Farmers have an increased risk of disability pension compared with higher grade professionals, but the risk is lower than in most other manual occupational groups. Farmers who report high levels of depression or anxiety symptoms are at substantially increased risk of future work disability, and the risk increase appears to be fairly similar across most occupational groups.

To assess whether nutritional deficiency increases susceptibility to arsenic-related health effects. Assessment of nutrition was based on a 24 h recall method of all dietary constituents. Epidemiological cross-sectional study was conducted in an arsenic endemic area of West Bengal with groundwater arsenic contamination. The study was composed of two groups – Group 1 (cases, n 108) exhibiting skin lesions and Group 2 (exposed controls, n 100) not exhibiting skin lesions – age- and sex-matched and having similar arsenic exposure through drinking water and arsenic levels in urine and hair. Both groups belonged to low socio-economic strata (Group 1 significantly poorer, P<0·01) and had low BMI (prevalence of BMI<18·5 kg/m2: in 38% in Group 1 and 27% in Group 2). Energy intake was below the Recommended Daily Allowance (set by the Indian Council of Medical Research) in males and females in both groups. Increased risk of arsenical skin lesions was found for those in the lowest quintile of protein intake (v. highest quintile: OR=4·60, 95% CI 1·36, 15·50 in males; OR=5·62, 95% CI 1·19, 34·57 in females). Significantly lower intakes of energy, protein, thiamin, niacin, Mg, Zn and choline were observed in both males and females of Group 1 compared with Group 2. Significantly lower intakes of carbohydrate, riboflavin, niacin and Cu were also observed in female cases with skin lesions compared with non-cases. Deficiencies of Zn, Mg and Cu, in addition to protein, B vitamins and choline, are found to be associated with arsenical skin lesions in West Bengal.

Purpose We evaluated the long-term effects of loxoprofen on nocturia in patients with benign prostatic hyperplasia (BPH). Materials and Methods Between January 2006 and December 2008, 40 BPH patients with 2 or more episodes of nocturia received an alpha-blocker, 5-alpha reductase inhibitor, and a single dose of 60 mg of loxoprofen at night before sleep for 12 months (Group I). During the same period, 38 BPH patients selected as the control group received an alpha-blocker and 5-alpha reductase inhibitor (Group II). Patients were reevaluated after 3, 6, and 12 months of treatment by the number of nocturia episodes and side effects. Results After 3 months of treatment, the number of nocturia episodes decreased significantly compared with baseline in both group I and group II (1.9±0.7, 2.1±0.7, respectively, p<0.05). The degree of decrease in nocturia was significantly different between the groups (-1.5±0.9, -1.1±0.9, respectively, p=0.034). After 6 and 12 months, the number of nocturia episodes decreased significantly compared with baseline in both group I and group II (p<0.05), but the degree of decrease was not significantly different between the groups (p>0.05). After 6 and 12 months of treatment in group I, treatment-emergent adverse events, including 5 cases of gastric discomfort (12.5%), 3 cases of leg edema (7.5%), and 1 case of decreased urine volume (2.5%), occurred in 9 of the 40 (22.5%) patients. Conclusions Loxoprofen can be an effective treatment for patients with nocturia secondary to BPH in the short term. Long-term use of loxoprofen is not recommended because of the side effects.

To observe the clinical effect differences between infraoccipital needle-knife and massage for cervical vertigo. A total of 366 patients with cervical vertigo were randomly assigned into a needle-knife group (186 cases) and a massage group (180 cases). With cases dropping excluded, 183 cases in the needle-knife group and 176 cases in the massage group were included. Needle-knife was used at Fengchi (GB 20), infraoccipital ashi point, etc. in the needle-knife group. The treatment was given for one course, once three days, 5 times as one course. The traditional massage was applied in the massage group for one course, including systematic stroking, kneading, and the application of pressure and plucking, etc., once every two days and 7 times as one course. The dizziness handicap inventory (DHI) score was observed before and after treatment, as well as 3, 6, and 12 months after treatment. The effects were also evaluated. The total effective rate was 92.3% (169/183) in the needle-knife group, which was better than 85.2% (150/176) in the massage group ( P <0.05). Compared with those before treatment, the DHI scores at all the observation time points after treatment were improved in the two groups (all P <0.05), with better improvements after treatment as well as 3 and 6 months after treatment in the needle-knife group (all P <0.05). There was no significant difference in the improvement of DHI scores between the two groups 12 months after treatment ( P >0.05). The recurrence rate was 10.3% (12/117) in the needle-knife group, and it was 10.7% (11/103) in the massage group 12 months after treatment ( P >0.05). Infraoccipital needle-knife achieves apparent effect for cervical vertigo, which is superior to massage in short period.

To investigate long-term effects on glycaemic control, ketoacidosis, serious hypoglycaemic events, insulin requirements, and body mass index standard deviation scores (BMI-SDS) in children and adolescents with type 1 diabetes starting on continuous subcutaneous insulin infusion (CSII) compared with children and adolescents treated with multiple daily injections (MDI). This retrospective case-control study compares 216 patients starting CSII with a control group on MDI (n = 215), matched for glycated hemoglobin (HbA1c), sex, and age during a 2-yr period. Variables collected were gender, age, HbA1c, insulin requirement, BMI, BMI-SDS, ketoacidosis, and serious hypoglycaemic events. In the CSII group there was an improvement in HbA1c after 6 and 12 months compared with the MDI group. For boys and girls separately the same effect was detected after 6 months, but only for boys after 12 months. The incidence of ketoacidosis was higher in the CSII group compared with the MDI group (2.8 vs. 0.5/100 person-yr). The incidences of severe hypoglycaemic episodes per 100 person-yr were three in the CSII group and six in the MDI group (p < 0.05). After 6, 12, and 24 months, the insulin requirement was higher in the MDI group. This study shows that treatment with CSII resulted in an improvement in HbA1c levels up to 1 yr and decreased the number of severe hypoglycaemic events, but the frequency of ketoacidosis increased. The major challenge is to identify methods to maintain the HbA1c improvement, especially among older children and teenagers, and reduce the frequency of ketoacidosis. © 2014 John Wiley & Sons A/S.

We examined the benefit of tissue plasminogen activator (tPA), delivered as part of usual stroke management, on patient-reported outcomes and health care utilization. Using a case control design, patients who received tPA as part of usual stroke management were compared with patients who would have received tPA had they arrived to the hospital within the therapeutic time window. Data were collected from surveys 6 months after stroke using standardized patient-reported outcome measures and questions about health care utilization. Demographic and medical data were acquired from hospital records. Patients were matched on stroke severity, age, race, and gender. Matching was done with 1:2 ratio of tPA to controls. Results were compared between groups with 1-tailed tests because of a directionally specific hypothesis in favor of the tPA group. The tPA (n = 78) and control (n = 156) groups were matched across variables, except for stroke severity, which was better in the control group; subsequent analyses controlled for this mismatch. The tPA group reported better physical function, communication, cognitive ability, depressive symptomatology, and quality of life/participation compared with the control group. Fewer people in the tPA group reported skilled nursing facility stays, emergency department visits, and rehospitalizations after their stroke compared with controls. Reports of other postacute services were not different between groups. Although it is known that tPA reduces disability, this is the first study to demonstrate the effectiveness of tPA in improving meaningful, patient-reported outcomes. Thus, use of tPA provides a large benefit to the daily lives of people with ischemic stroke. Copyright © 2014 National Stroke Association. Published by Elsevier Inc. All rights reserved.

Thyroid function disorders lead to changes in the lipoprotein metabolism. To study the lipid and the glycaemic abnormalities in the subclinical hypothyroidism cases and to compare the same with the euthyroid, overt hypothyroid and the hyperthyroid subjects. Four groups, euthyroid (Group-I), hypothyroid (Group-II), subclinical hypothyroid (Group-III) and hyperthyroid (Group-IV), which consisted of 30 subjects each, of either sex, who were aged 25-55 years, underwent Fasting Plasma Glucose (FPG), fructosamine, lipid profile and total T3, T4 and TSH estimations. The subjects who were on lipid lowering or thyroid disorder drugs and known diabetics were excluded from the study. In Group-III, all the lipid fractions were comparable to those of Group-II and they were significantly deranged, as compared to those of Group-I. The fructosamine levels were significantly higher in Group-II and Group-III (p<0.05), but the subclinical hypothyroid pool had statistically lower levels than the hypothyroid pool (376.63±54.73, 587.80±65.10). In the Group-IV patients, the LDL-C levels were significantly higher as compared to those in the euthyroid pool. The fructosamine levels were significantly lower in comparison with both the euthyroid and the hypothyroid pools (both in Groups-II and III). The FPG levels were higher in all the classes of the thyroid abnormalities (subclinical hypothyroidnot significant) but within the reference range of 70-100mg/dl. Since the lipid derangement in subclinical hypothyroidism is on par with that in overt hypothyrodism, the subclinical hypothyroid cases also need to be treated similarly. The fructosamine values which are largely in excess of the FPG values, indicate a higher propensity to glycation and a decreased turnover of the proteins in the hypothyroid and the subclinical hypothyroid pools. Vice versa is true of the hyperthyroid pool. Fructosamine can be included in the thyroid work up of the patients to assess the metabolic function and the subsequent response after the initiation of the therapy.

Apolipoprotein E binds to {beta}-amyloid peptide in senile plaques and neurofibrillary tangles in Alzheimer`s disease (AD). Recent studies have identified the APOE*4 allele as a major predisposing genetic factor for late-onset familial AD as well as in sporadic AD. Most of these association studies are based on clinically diagnosed AD cases with little data available on autopsy confirmed, definite AD. To characterize the distribution of APOE polymorphism in autopsy confirmed sporadic AD cases, we determined APOE genotypes in 111 DNA samples (aged 51-101 years) extracted from brain tissues which were available from the University of Pittsburgh Alzheimer`s Disease Research Center.more » The APOE data was compared between the AD group and 3 samples of population controls from Western Pennsylvania consisting of a young cohort (N=473, aged 18-48 years), middle cohort (N=473, aged 42-50 years) and an old cohort (N=870, aged 65-90 years). The frequency of the APOE*4 allele was similar in the young and middle cohorts (0.12) and slightly lower in the old cohort (0.10). However, the frequency of the APOE*4 allele was three times higher in both early-onset (<65 years; 0.36) and late-onset ({ge}65 years; 0.38) sporadic AD cases compared to the control groups (p<0.0001). In the AD cohort the frequency of the APOE*4 allele was similar across all age groups (<65, 65-75, 76-85, 86+) and so was in men and women (0.40 vs. 0.37). The E*4 homozygosity was observed in 18% of AD cases compared to 1% in each of the three control groups. The E*4 heterozygosity was present in 50% of AD cases compared to 17% in the control old cohort and 22% in both the young and middle control cohorts. These data confirm that the APOE*4 allele is a major risk factor for AD regardless of age-at-diagnosis or family history.« less

High-fidelity patient simulation (HFPS) has been used in medical education to bridge gaps in medical knowledge and clinical skills. Few studies have analyzed the impact of HFPS in subspecialty rotations for pediatric residents. We hypothesized that pediatric residents exposed to HFPS with a structured content curriculum would perform better on a case quiz than residents without exposure to HFPS. Prospective randomized controlled Tertiary-care free standing children's hospital During a cardiology rotation, senior pediatric residents completed an online pediatric cardiology curriculum and a cardiology quiz. After randomization into two groups, the study group participated in a fully debriefed HFPS session. The control group had no HFPS. Both groups completed a case quiz. Confidence surveys pre- and postsimulation were completed. From October 2010 through March 2013, 55 residents who rotated through the pediatric cardiology rotation were used in the final analysis (30 control, 25 in the study group). There was no significant difference between groups on the initial cardiology quiz. The study group scored higher on the case quiz compared with the control group (P = .024). Based on pre- and postsimulation questionnaires, residents' confidence in approaching a pediatric cardiology patient improved from an average Likert score of 5.1 to 7.5 (on scale of 0-10) (P < .001). Incorporation of HFPS into a preexisting pediatric cardiology rotation was feasible and well received. Our study suggests that simulation promotes increased confidence and may modestly improve clinical reasoning compared to traditional educational techniques. Targeted simulation sessions may readily be incorporated into pediatric subspecialty rotations. © 2014 Wiley Periodicals, Inc.

To summarize the clinical characteristics of whooping cough in children and analyze the risk factors for severe whooping cough. A retrospective analysis was made on the clinical data of 247 children with whooping cough in Children's Hospital of Chongqing Medical University between Jan 2013 and Dec 2014. Of these patients, 126 were male, 121 were female, the median age was 3.1 months (23 days-4 years and eight months old). The patients were divided into two groups, group 1 had infants less than 3 months of age (n=120) and group 2 had infants and young children older than 3 months (n=127) according to their age. On the other hand, the patients were also divided into two groups according to vaccination status: vaccinated group (received diphtheria toxoid, tetanus toxoid, and acellular pertussis, DTP) (n=31) and unvaccinated group (n=188). Pure Bordetella pertussis infection was seen in 106 cases, and 141 cases had mixed infection. Severe disease was seen in 13 cases, and the other 234 cases had the modest disease. Clinical data were retrospectively analyzed and compared. (1) Bordetella pertussis was identified in 57/680 cases (8.4%) in 2013, and 190/1 856 cases (10.2%) in 2014. The disease could be seen throughout the year, but 182 cases (73.7%) occurred in summer or autumn; 202 cases (81.8%) were less than 6 months. (2) Paroxysmal cough was seen in 238 cases (96.4%) , 61 cases (24.7%) had inspiratory whoop. Infants in group 1 often had episodes of cyanosis, apnea and suffocation (χ² = 19.999, 12.081, 6.508, P<0.05), persistent cough was often seen in group 2 (χ² = 9.885, P<0.05). Complications such as severe pneumonia, pulmonary consolidation and encephalopathy were more common in the group 1 than in group 2 (χ² = 17.340, 6.080, 11.030, 23.545, P<0.05). (3) The length of stay of group 1, and of unvaccinated group was significantly longer than that of group 2 and of vaccinated group (t=19.331, 26.741, P<0.05). (4) Leukocytosis was found in 224 cases (90.7%), 182 cases (73.7%) had predominant lymphocytosis. White blood cell in group 1, unvaccinated group and severe disease group was higher than the corresponding group (t=11.075,13.739,3.469, P<0.05). (5) Patients who had a history of exposure, fever, leukocytosis and pulmonary consolidation or atelectasis on chest imaging were prone to develop into severe pertussis (OR=4.521, 4.900, 1.085, 4.792, 50.400; P<0.05). A total of 244 cases (98.8%) recovered, 3 cases (1.2%) died, they were less than 3 months old and unvaccinated. The number of cases with whooping cough in Chongqing area tends to be rising. The disease occurred mostly in summer and fall. Infants less than 3 months old, unvaccinated with DTP had high susceptibility to pertussis, often had a severe clinical presentation and severe complications, had a high mortality rate.

Infections following a natural disaster such as an EF-5 tornado can be atypical and difficult to treat. Studies have looked at illness following several natural disasters, but few have studied respiratory illness following a tornado. A review of patients with pneumonia admitted during the period from May 22, 2009, through May 21, 2012, was completed. The Tornado Zone Group included adult patients who lived or worked in the tornado zone during the year following the tornado. Data were isolated by number of pneumonia cases within and outside the tornado zone per month per year. An analysis of variance comparing the number of pneumonia cases from the tornado zone per month per year was significant at F2,38 = 12.93 and P < .001, with increased cases in the Tornado Zone Group (P < .05). A t test comparing age of pneumonia patients found Tornado Zone patients to be younger than controls (t390 = 5.14; P < .01). Microbes isolated from the Tornado Zone Group included uncommon pathogens not isolated during the 2 years prior. The number of pneumonia cases may increase following tornadoes. Although current guidelines recommend narrow-spectrum antibiotics for community-acquired pneumonia, results of this study suggest the possible need for broader antimicrobial coverage after tornadoes.

To explore the chemopreventive effect of curcumin on DMH induced colorectal carcinogenesis and the underlining mechanism. Totally 40 Wistar rats were divided into the model group and the curcumin group by random digit table, 20 in each group. Meanwhile, a normal control group was set up (n =10). A colorectal cancer model was induced by subcutaneously injecting 20 mg/kg DMH. The tumor incidence and the inhibition rate were calculated. The effect of curcumin on the expression of peroxisome proliferator-activated receptor gamma (PPARγ) in rat colon mucosal tissues was observed using immunohistochemistry and Western blot. HT 29 cell line were cultured and divided into a control group, the curcumin + GW9662 (2-chloro-5-nitro-N-4-phenylbenzamide) intervention group, and the curcumin group. The inhibition of different concentrations curcumin on HT29 cell line was detected using MTT. The expression of curcumin on PPARy was also detected using Western blot. The tumor incidence was 80. 00% (12/15 cases) in the model group, obviously higher than that of the curcumin group (58. 82%, 10/17 cases, P <0. 05). The inhibition rate of curcumin on DMH induced colorected carcinoma reached 26. 46%. Compared with the normal control group, the expression of PPARγ protein was significantly increased in the curcumin group and the model group (P <0. 01). Compared with the model group at the same time point, the expression of PPARy protein was significantly enhanced in the curcumin group (P <0. 05). MTT analysis showed that curcumin could inhibit the proliferation of in vitro HT 29 cells in dose and time dependent manners. The expression of PPARy protein was significantly increased in the GW9662 group and the curcumin group, showing statistical difference when compared with the normal control group (P <0. 01). Compared with the GW9662 group, the expression of PPARγ protein was significantly increased in the curcumin group (P <0. 01). Curcumin could inhibit DMH-induced rat colorectal carcinogenesis and the growth of in vitro cultured HT 29 cell line, which might be achieved by activating PPARy signal transduction pathway.

To evaluate the efficiency of our treatment of vaginal infection for couples included in an IVF program. Microbiologic screening of vaginal flora and semen has been performed one month prior to in vitro fertilization for 951 couples in 2000. Antibiotic treatment was prescribed in case of positive culture. Positive microbial growths were observed from endocervical and vaginal cultures in 218 women (22.9%). The clinical pregnancy rate was 30.29% in the group of patients without growth and 30.27% in the group with positive microbial growth. The implantation rate was significantly diminished in case of bacterial growth: 14.6 compared to 19.3% (P <0.02) for sterile endocervical culture. Five main bacterial species were found at the cervical level: Candida albicans (69 cases), Ureaplasma urealyticum (49 cases), Gardnerella vaginalis (43 cases), Streptococcus B or D (24 cases) and Escherichia coli (22 cases). Positive cultures from both vagina and semen were observed for 77 couples whose clinical pregnancy rate was 19.5 vs 36.2% in case of vaginal infection alone (P <0.01) with a spontaneous miscarriage rate of 46.7 compared to 17.6% (P <0.01). Endocervical microorganisms, even treated with adapted antibiotics, may affect embryonic implantation. Positive culture from both female and male partner may enhance this negative effect. In this case, the best strategy would be to cancel the IVF treatment.

Comparison of the CENTRM resonance processor to the NITAWL resonance processor in SCALE

This report compares the MTAWL and CENTRM resonance processors in the SCALE code system. The cases examined consist of the International OECD/NEA Criticality Working Group Benchmark 20 problem. These cases represent fuel pellets partially dissolved in a borated solution. The assumptions inherent to the Nordheim Integral Treatment, used in MTAWL, are not valid for these problems. CENTRM resolves this limitation by explicitly calculating a problem dependent point flux from point cross sections, which is then used to create group cross sections.

As epilepsy affects approximately one percent of the world population, electrical stimulation of the brain has recently shown potential for additive seizure control therapy. In this study we applied noninvasive transcranial focal stimulation (TFS) via concentric ring electrodes on the scalp of rats after inducing seizures with pentylenetetrazole (PTZ) to assess the effect of TFS on the electrographic activity. Grand average power spectral densities were calculated to compare different stages of seizure development. They showed a significant difference between the TFS treated group and the control group. In case of the TFS treated group, after TFS, the power spectral density was reduced further towards a pre-seizure "baseline" than it was for the control group. The difference is the most drastic in delta, theta and alpha frequency bands. Application of general likelihood ratio test showed that TFS significantly (p<0.001) reduced the power of electrographic seizure activity in the TFS treated group compared to controls in more than 86% of the cases. These results suggest that TFS may have an anticonvulsant effect.
