    It is reported that surveillance of serum p53 antibody (Ab) is a useful marker in detecting esophageal squamous cell carcinoma (ESCC). But there is little reported about prognostic significance of serum p53-Ab in postoperative patients with ESCC. The aim of this study is to evaluate the significance of preoperative serum p53-Ab as a marker of early recurrence after curative resection for ESCC. Enzyme-linked immunosorvent assay (ELISA) was used to analyze serum p53-Ab before treatment in 44 patients with ESCC. Carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCC-Ag) were examined by immunoradiometric assay. The patients who were strongly positive and positive in serum p53-Ab were more likely to have early recurrence after curative resection than seronegative patients. There were no significant correlations between CEA, SCC-Ag positivity and early recurrence. We found that serum p53-Ab was useful to predict a risk of early recurrence after curative surgical resection for ESCC.

    In 40 premenopausal women who underwent TAH&BSO serum E2 levels were measured by means of RIA in 3 time points: before the operation, in the postoperative day 2 and in the postoperative day 3. In 20 of the subjects the ERT (transdermal estradiol 0.1 g/24 h) was introduced in the 2 postoperative day. In the postoperative day 2 the average serum E2 decreased by nearly 90% as compared to the preoperative values. Twenty four hours after the application of the transdermal E2 patch, the estradiol level returned to the values insignificantly different from the preoperative ones. PMID:11883283

    Measuring CA15.3 serum levels in the early breast cancer setting is not recommended by current ASCO guidelines. In this large single center study, we assess the prognostic value of preoperative (n = 3746), postoperative (n = 4049) and change in (n = 3252) CA15.3, also across different breast cancer phenotypes. Preoperative, postoperative and change in CA15.3 were all significant (p = 0.0348, p < 0.0001, p < 0.0001 respectively in multivariate analysis) predictors of distant metastasis free survival. For breast cancer specific survival, only postoperative and change in CA15.3 were significant predictors (p < 0.0001 both). Multivariate prognostic models did not improve by incorporating information on preoperative CA15.3, but did improve when introducing information on postoperative CA15.3 for distant metastasis (p = 0.0365) and on change in CA15.3 for breast cancer specific survival (p = 0.0291). Change in CA15.3 impacts on prognosis (distant metastasis) differently in different breast cancer phenotypes. A decrease in CA15.3 may be informative of improved prognosis in basal like and HER2 like breast cancer.

    Liver transplantation is a highly successful treatment for patients with end-stage liver disease and acute liver failure. However, serious postoperative complications can significantly compromise patient survival. Complications can be technical, medical, or immunological in nature. The risk of developing early postoperative complications is associated with the patient's preoperative condition, the quality of the donor liver, the quality of the donor and recipient procedure, initial graft function, and perioperative anaesthesiological and intensive care management. The patient's preoperative condition can include gastrointestinal bleeding, acute renal failure, a requirement for cathecholamines or mechanical ventilation, and prolonged encephalopathy for the most detrimental risk factors for developing early postoperative complications. The necessity for prolonged mechanical ventilation or the requirement for reintubation after transplantation can significantly increase the risk of developing pneumonia, sepsis, and multiple organ dysfunction. A decrease in infectious and other complications can be achieved by early postoperative enteral nutition, including the application of probiotics. PMID:15494284

    This article reviews early postoperative complications in adults undergoing ostomy surgery. Whether the ostomy is the result of an emergent or elective procedure, the WOC nurse and staff nurses are responsible for monitoring and ensuring quality healthcare for the patient. Nevertheless, many patients undergoing ostomy surgery experience a complication during the early postoperative period. Early postoperative complications not only influence immediate postoperative care but may also impact quality of life for the person living with an ostomy. Keen assessment skills, early recognition of signs and symptoms of a complication, and prompt interventions are crucial to maintaining a viable stoma and a successful surgical outcome.

    In 44 patients undergoing neurosurgical procedures for intracranial tumors, subarachnoid hemorrhage, or spinal and peripheral nerve lesions, serum myelin basic protein (MBP) immunoreactivity was measured preoperatively and serially in the first 10 postoperative days. The double-antibody radioimmunoassay method was used, with a detection limit of 2.5 ng/ml in serum. Clinical evaluation was carried out at admission and on successive days during the period of neurosurgical management; outcome was assessed later. In the early postoperative phase, there was a fall in MBP immunoreactivity in all groups of patients. In the groups with intracranial tumor and subarachnoid hemorrhage, there was a subsequent rise in MBP immunoreactivity before the end of the 10-day period, which was not found in the group with spinal and peripheral nerve lesions.

    1989-09-01

    The author suspected that the high incidence of early recurrence after macroscopically curative operation in human liver cancers correlated with the production of liver regeneration factor which was induced following partial hepatectomy (PH). The author therefore analyzed whether PH enhanced the growth of liver cancers or not, and the relevant mechanism involved, using rats subcutaneously injected with hepatocellular carcinoma (KDH-8, AH-66) cells. Primarily, it proved that PH significantly enhanced the growth of liver cancers injected in rats. The effect of this enhancement of liver cancer growth appeared as an abrupt increase in tumor volume within 24 hours following PH, which fact was supported by the mitotic indices of the hepatocellular carcinoma (KDH-8) cells. However PH did not affect rats injected with mammary carcinoma (SST-2) cells without estrogen receptor (E2R) or fibrosarcoma (KMT-75) cells. Secondly, based on this result, the author tried to analyze the mechanism of enhanced growth of liver cancers following PH, from the standpoints of; changes in postoperative immunity, expression of cytosol E2R in liver cancer cells or liver regeneration factor, using KDH-8 cells. The changes in postoperative immunity (NK-activity and Blastogenesis) did not correlate with the changes in liver cancer growth. Although serum estradiol (E2) increased significantly after PH, E2R was not detected in the KDH-8 cells used in this experiment. Serum was obtained from healthy rats 24 hours after PH, and 20 mg of serum, as calculated from total protein, was eluted into 50 fractions by high liquid chromatography (column; TSK G3000 SW). When the author examined which fractions stimulated both the growth of primarily cultivated hepatocytes and KDH-8 cells, only the fraction Fr. 30, the molecular weight of which was about 100 Kd, enhanced both. Furthermore, the author performed an in vivo assay to determine the number of days needed for tumor appearance: PHs were carried out 2

    We retrospectively examined esophageal cancer patients who received enteral nutrition (EN) to clarify the validity of early EN compared with delayed EN. A total of 103 patients who underwent transthoracic esophagectomy with three-field lymphadenectomy for esophageal cancer were entered. Patients were divided into two groups; Group E received EN within postoperative day 3, and Group L received EN after postoperative day 3. The clinical factors such as days for first fecal passage, the dose of postoperative albumin infusion, differences of serum albumin value between pre- and postoperation, duration of systematic inflammatory response syndrome (SIRS), incidence of postoperative infectious complication, and use of total parenteral nutrition (TPN) were compared between the groups. The statistical analyses were performed using Mann-Whitney U test and Chi square test. The statistical significance was defined as p < 0.05. Group E showed fewer days for the first fecal passage (p < 0.01), lesser dose of postoperative albumin infusion (p < 0.01), less use of TPN (p < 0.01), and shorter duration of SIRS (p < 0.01). However, there was no significant difference in postoperative complications between the two groups. Early EN started within 3 days after esophagectomy. It is safe and valid for reduction of albumin infusion and TPN, for promoting early recovery of intestinal movement, and for early recovery from systemic inflammation. PMID:24067386

    Background Circulating biomarkers can predict clinical outcomes in colorectal cancer patients. The aim of the study was to evaluate the feasibility of our multigene biomarker chip for detecting circulating tumor cells for postoperative surveillance of stage I–III colorectal cancer patients. Materials and Methods In total, 298 stage I–III colorectal cancer patients were analyzed after curative resection between June 2010 and October 2014. During each follow-up, a postoperative surveillance strategy, including ESMO Guidelines Working Group recommendations and the biochip, was used. Results After a 28.4-month median follow-up, 48 (16.1%) patients had postoperative relapse. Univariate analysis revealed that the postoperative relapse risk factors were rectal tumor, perineural invasion, elevated preoperative and postoperative serum carcinoembryonic antigen levels, and positive biochip results (all P < 0.05). Multivariate analyses revealed that postoperative relapse correlated significantly with elevated postoperative serum carcinoembryonic antigen levels (odds ratio = 4.136, P = 0.008) and positive biochip results (odds ratio = 66.878, P < 0.001). However, the sensitivity (P = 0.003), specificity (P = 0.003), positive (P = 0.002) and negative (P = 0.006) predictive values, and accuracy (P < 0.001) of the biochip for predicting postoperative relapse were significantly higher than those of elevated postoperative serum carcinoembryonic antigen levels. Moreover, the median lead time between positive biochip result and postoperative relapse detection was significantly earlier than that between elevated postoperative serum carcinoembryonic antigen level and postoperative relapse detection (10.7 vs. 2.8 months, P < 0.001). Furthermore, positive biochip results correlated strongly with lower disease-free survival and overall survival of colorectal cancer patients (both P < 0.001). Conclusion Compared with conventional serum carcinoembryonic antigen detection, our multigene

    Several medical complications can occur after scoliosis surgery in children and adolescents. New surgical techniques have allowed greater degrees of scoliosis correction but have also increased the possibility of postsurgical deficit due to their greater aggressivity. We analyzed the early postsurgical complications of scoliosis surgery in a pediatric intensive care unit over a 10-year period. Seventy-six surgical procedures were performed. Of these, no complications occurred in 55 (73%). Chest X-ray revealed pulmonary atelectasia in 8 patients (10%) and pleural effusion in 7 patients (9%). Symptoms and signs of infection related to surgery were observed in only 6 children (8%). The absence of severe medical complications may be related to new surgical techniques and an experienced team. PMID:16527092

    Background The literature does not provide consistent information on the impact of patients' gender on recovery after rotator cuff repair. The purpose of this study was to determine whether gender affects pain and functional recovery in the early postoperative period after rotator cuff repair. Methods Eighty patients (40 men and 40 women) were prospectively enrolled. Pain intensity and functional recovery were evaluated, using visual analog scale (VAS) pain score and range of motion on each of the first 5 postoperative days, at 2 and 6 weeks and at 3, 6, and 12 months after surgery. Perioperative medication-related adverse effects and postoperative complications were also assessed. Results The mean VAS pain score was significantly higher for women than men at 2 weeks after surgery (p = 0.035). For all other periods, there was no significant difference between men and women in VAS pain scores, although women had higher scores than men. Mean forward flexion in women was significantly lower than men at 6 weeks after surgery (p = 0.033) and the mean degree of external rotation in women was significantly lower than men at 6 weeks (p = 0.007) and at 3 months (p = 0.017) after surgery. There was no significant difference in medication-related adverse effects or postoperative complications. Conclusions Women had more pain and slower recovery of shoulder motion than men during the first 3 months after rotator cuff repair. These findings can serve as guidelines for pain management and rehabilitation after surgery and can help explain postoperative recovery patterns to patients with scheduled rotator cuff repair.

    We evaluated postoperative function in 98 patients who underwent surgery for early gastric cancer between 1995 and 1998 to compare the results of pylorus-preserving procedures to those of conventional distal gastrectomy with Billroth I (B-I). The pylorus-preserving procedures included endoscopic mucosal resection (EMR), performed in 12 patients; local resection (Local), performed in 14 patients; segmental resection (Seg), performed in 8 patients; and pylorus-preserving gastrectomy (PPG), performed in 19 patients. B-I was performed in 45 patients. The nutritional status and serum albumin (Alb) levels after PPG, the hemoglobin (Hb) levels after EMR, Local, and PPG, and the present/preoperative body weight ratios after EMR, Local, Seg, and PPG were superior to those after B-I. The time before oral intake was recommenced after EMR and Local, the volume of oral intake tolerated after EMR, Local, Seg, and PPG, and the postoperative hospital stay after EMR were all superior to those after B-I. Moreover, significantly fewer patients suffered reflux symptoms after EMR, Local, and PPG, abdominal fullness after EMR, and early dumping syndrome after EMR, Local, and PPG than after B-I. There was also less evidence of gastritis after EMR, Local, and PPG, and of bile reflux after EMR, Local, and PPG, than after B-I. These findings indicate that pylorus-preserving procedures may result in a better postoperative quality of life for selected patients with early gastric cancer.

    The article is dedicated to investigating the reasons of development of hypoxemia during the early postoperative period when the patient is switched to an unassisted air breathing. It was established that hypoxemia develops, after abdominal operations with a multi-component total anesthesia, in 68% of patients, although there is a recovery of adequate ventilation of the lungs, and it is related with an insufficient anesthesia, which results in an increased volume of expiratory closure. Epidural anesthesia prevents an increase in the closure volume and development of hypoxemia.

    The effects of early postoperative radiation were assessed in free nonvascularized and free vascularized rib grafts in the canine model. The mandibles of one-half of the dogs were exposed to a cobalt 60 radiation dose of 4080 cGy over a 4-week period, starting 2 weeks postoperatively. The patency of vascularized grafts was confirmed with bone scintigraphy. Histological studies, including ultraviolet microscopy with trifluorochrome labeling, and histomorphometric analyses were performed. Osteocytes persist within the cortex of the vascularized nonradiated grafts to a much greater extent than in nonvascularized, nonradiated grafts. Cortical osteocytes do not persist in either vascularized or nonvascularized grafts subjected to radiation. New bone formation is significantly retarded in radiated grafts compared with nonradiated grafts. Periosteum and endosteum remained viable in the radiated vascularized grafts, producing both bone union and increased bone turnover, neither of which were evident to any significant extent in nonvascularized grafts. Bone union was achieved in vascularized and non-vascularized nonradiated bone. In the radiated group of dogs, union was only seen in the vascularized bone grafts.

    Purpose It is well known that old age is a risk factor for postoperative complications. Therefore, this study aimed to explore the risk factors for poor postoperative surgical outcomes in elderly gastric cancer patients. Materials and Methods Between January 2006 and December 2015, 247 elderly gastric cancer patients who underwent curative gastrectomy were reviewed. In this study, an elderly patient was defined as a patient aged ≥65 years. All possible variables were used to explore the risk factors for poor early surgical outcomes in elderly gastric cancer patients. Results Based on multivariate analyses of preoperative risk factors, preoperative low serum albumin level (<3.5 g/dl) and male sex showed statistical significance in predicting severe postoperative complications. Additionally, in an analysis of surgery-related risk factors, total gastrectomy was a risk factor for severe postoperative complications. Conclusions Our study findings suggest that low serum albumin level, male sex, and total gastrectomy could be risk factors of severe postoperative complications in elderly gastric cancer patients. Therefore, surgeons should work carefully in cases of elderly gastric cancer patients with low preoperative serum albumin level and male sex. We believe that efforts should be made to avoid total gastrectomy in elderly gastric cancer patients. PMID:27104026

    Background This study aimed to evaluate the effects of lidocaine treatment on cognitive impairment in aged patients undergoing spine surgery and to explore the underlying mechanism. Material/Methods Patients were randomly divided into 2 treatment groups: (1) saline (control) and (2) lidocaine. After induction of anesthesia, the lidocaine group received lidocaine as a bolus of 1 mg/kg over 5 minutes, followed by a continuous infusion at 1.5 mg/kg/h until the end of the surgery. We examined the effects of lidocaine treatment on the improvement of cognitive function using the Mini-Mental State Examination (MMSE) at preoperation and 3 days postoperation. Serum samples were collected to assess the levels of IL-6, TNF-α, MDA, S100β, and NSE before inducing anesthesia, at the end of surgery, and 3 days after the end of surgery. Results We found that the MMSE scores in the lidocaine group were markedly higher than those in the control group at 3 days after surgery. Moreover, lidocaine treatment markedly suppressed the release of IL-6, S100β, and NSE into the serum at the end of surgery and 3 days after the end of surgery. In the control group, serum MDA levels increased by 3 days after the end of surgery. The lidocaine group had lower serum MDA levels than those in the control group. Conclusions Lidocaine may be an effective neuroprotective agent in treating early postoperative cognitive dysfunction in elderly patients undergoing spine surgery. PMID:25975969

    Postoperative fatigue syndrome is a general complication after surgery. However, there is no ‘‘gold standard’’ for fatigue assessment due to the lack of objective biomarkers. In this study, a rodent model of postoperative fatigue syndrome based on partial hepatectomy was firstly established and serum metabonomic method based on ultra-high performance liquid chromatography coupled with Q-TOF mass spectrometry was applied. Partial least-squares discriminant analysis was used to identify the differential metabolites in 70% partial hepatectomy rats relative to sham rats and 30% partial hepatectomy rats, which showed 70% partial hepatectomy group was significantly distinguishable from 30% partial hepatectomy group and sham group. Eighteen serum metabolites responsible for the discrimination were identified. The levels of hypoxanthine, kynurenine, tryptophan, uric acid, phenylalanine, palmitic acid, arachidonic acid and oleic acid showed progressive elevation from sham group to 30% partial hepatectomy group to 70% partial hepatectomy group, and levels of valine, tyrosine, isoleucine, linoleyl carnitine, palmitoylcarnitine, lysophosphatidylcholine (16:0), lysophosphatidylcholine (20:3), citric acid, succinic acid and hippuric acid showed progressive declining trend from sham group to 30% partial hepatectomy group to 70% partial hepatectomy group. These potential biomarkers help to understand of etiology, pathophysiology and treatment of postoperative fatigue syndrome. PMID:27257346

    ABSTRACT Background: Roux-en-Y gastric bypass is one of the most common bariatric surgery and leads to considerable weight loss in the first months. Aim: To quantify the main early postoperative complications in patients submitted to the gastric bypass. Method: Observational retrospective cohort. Data of 1051 patients with class II obesity associated with comorbidities or class III obesity submitted to the gastric bypass with 30 days of follow-up starting from the date of the surgery. Results: The age average was 36 years with a predominance of females (81.1%). The mean preoperative body mass index was 43 kg/m². The major complication was fistula (2.3%), followed by intestinal obstruction (0.5%) and pulmonary embolism (0.5%). Death occurred in 0.6% of the cases. Conclusion: In the period of 30 days after surgery the overall complication rate was 3.8%; reoperation was necessary in 2.6% and death occurred in 0.6%. Fistula was the main complication and the leading cause of hospitalization in intensive care unit, reoperation and death. PMID:27683781

    Breast cancer is still an enigma. Systemic metastasis is an important prognostic factor. Tumour marker can predict occult systemic metastasis. To evaluate the immediate postoperative CA15.3 as predictor of early recurrence, a study was carried out in 48 patients of carcinoma breast in whom immediate postoperative marker level was done. In follow-up, recurrence was noted and relation with tumour size and stage done. Null hypothesis and 't' test were used for analysis. Relation of tumour size with marker is weak but strong relation exists between tumour stage with marker and recurrence with marker. CA15.3 predicts tumour load, can also predict occult residual/occult metastatic disease better than other prognostic markers which only predict tumour behaviour.

    It is well established that the nutritional state greatly influences tolerance during the operation. Authors present a new procedure for the early postoperative enteral alimentation having not been used in Hungary so far. Twelve hours after operation, a pump-operated, gradually increasing amount of oligopeptide food-preparation and concentrate is introduced continuously into the second jejunal loop intraoperatively. Using this method, a caloric intake of 9572 kJ can be achieved already from the fourth postoperative day onwards. Based on our experience gained from 32 patients, the method can be recommended for an up-to-date postoperative enteral alimentation.

The complications rate almost did not change, but their structure--essentially. The occurrence rate for eventration, adhesive ileus, relaparotomy performance for abdominal cavity abscess have had lowered significantly due to introduction of a new operative technologies and prophylactic measures. The lowering of lethality after relaparotomy is caused by improvement of the complications diagnosis, timely performance of reoperations, application of laparostomy in the treatment of postoperative peritonitis, what have permitted to govern a postoperative period course.

    The effect of enteral administration of tributyrin on electrical activity in the upper segments of the small intestine was examined in rats on the model of postoperative ileus. This postoperative state is characterized with pronounced and long-term disturbances in generation of migrating myoelectric complex of the small intestine. The enteral administration of tributyrin in the early postoperative period aimed to suppress the non-adrenergic non-cholinergic influences and activation of the cholinergic anti-inflammatory pathways is an effective procedure to normalize the migrating myoelectric complex and therefore the coordinated propulsive peristalsis in the small intestine.

    In a study made in the follow-up clinic on 684 patients with mammary carcinoma it was found that there were 64 cases of local recurrence and 244 cases of distant metastases. In both groups the serum iron and the serum copper balance in blood tests, in relation to the clinical proof of local recurrence and/or distant metastases, was investigated. It was found that there were 43.7% pathological serum iron and serum copper findings with local recurrences and 62.7% with distant metastases. The drift apart tendency of the blood serum values in patients with distant metastases could be proved in 78.7% of the cases and in 77.5% of the cases before any clinical proof. Thus, these observations allow the statement that the blood serum iron and serum copper imbalance in blood tests is of very real value in the early diagnosis of distant metastases.

    We aimed to determine the factors predicting liver cirrhosis-related complications in the early postoperative period after lung cancer surgery in patients with liver cirrhosis. We retrospectively reviewed the medical records of patients who underwent curative surgery for primary lung cancer in our institute from January 1990 to March 2007, finding 37 cases with comorbid liver cirrhosis. These patients were divided into two groups, according to whether liver failure, bleeding, and critical infection had occurred postoperatively. Various clinical parameters were analyzed statistically between the bigeminal groups. Liver cirrhosis-related complications occurred in seven of the 37 patients (18.9%). Transient liver failure occurred in two patients (5.4%) after pulmonary resection. Acute intrathoracic bleeding occurred in four cases (10.8%). Two patients died (5.4%) in both cases due to sepsis. Preoperative total bilirubin (P<0.05), and indocyanine green retention rate at 15 min (P<0.05) were significantly higher in patients with liver failure. Only serum value of total bilirubin was an independent risk factor (P<0.05) by multivariate analysis. In predicting death from infection, only preoperative nutritional status was a significant risk factor (P<0.05). To avoid postoperative cirrhosis-related complications, preoperative preparation to improve their liver function and nutrition status is essential. PMID:17766277

    Six hundred and sixty-three patients were followed with serial serum CEA measurements in addition to routine clinical surveillance after radical resection of colorectal carcinoma. Of 626 available for analysis, 366 (58.4%) remained clinically free of recurrence and had a normal CEA (less than 20 ng ml-1) throughout and 89 (14.2%) had a temporary non-progressive rise in CEA with no evidence of secondary disease. Of 171 patients who developed proven or suggestive recurrence, 114 had a preceding rise in the serum CEA and in further 21 the CEA rose simultaneously with recurrence. In 36 patients secondary disease was detected while the CEA was still within normal limits. CEA was more effective as an early index of distant metastasis, thus in 76% of those patients with a preceding rise in CEA, the secondary disease was disseminated, whereas only 20% had localised recurrence. The pattern of rise in CEA was of no practical value in distinguishing localised from distant recurrence. PMID:6733018

    Purpose The purpose of this study was to evaluate the prognostic significance of serum CEA (s-CEA) changes in colorectal cancer (CRC) patients with sustained elevated postoperative s-CEA levels. Methods Between January 1999 and December 2008, 9,380 CRC patients underwent surgery. Curative resection was performed in 1,242 CRC patients with high preoperative s-CEA levels (>6 ng/mL). High s-CEA levels were normalized in 924 patients (74.4%) within 2 weeks from surgery, whereas high s-CEA levels were persistent in 318 patients (25.6%). Patients were divided into 2 groups according to their postoperative s-CEA levels: group 1 (37 patients with a 1-year postoperative s-CEA>6 ng/mL) and group 2 (281 patients with a 1-year postoperative s-CEA≤6 ng/mL). Results A postoperative recurrence was identified in 24 patients (64.9%) in group 1 and 65 patients (23.1%) in group 2 (P < 0.001). A curative resection after recurrence was performed in 22 patients (33.8%) from group 2, but no patients from group 1 (P = 0.001). The 5-year overall survival and time to recurrence were significantly lower in patients with recurrent cancer in group 1 (P < 0.001). Conclusion Patients with persistent elevated postoperative s-CEA levels are at high risk for recurrence and a low survival rate. More intensive surveillance of patients with high postoperative s-CEA levels should be mandatory. PMID:27757393

  9. Early postoperative cognitive dysfunction and postoperative delirium after anaesthesia with various hypnotics: study protocol for a randomised controlled trial - The PINOCCHIO trial

    PubMed Central

    2011-01-01

    Background Postoperative delirium can result in increased postoperative morbidity and mortality, major demand for postoperative care and higher hospital costs. Hypnotics serve to induce and maintain anaesthesia and to abolish patients' consciousness. Their persisting clinical action can delay postoperative cognitive recovery and favour postoperative delirium. Some evidence suggests that these unwanted effects vary according to each hypnotic's specific pharmacodynamic and pharmacokinetic characteristics and its interaction with the individual patient. We designed this study to evaluate postoperative delirium rate after general anaesthesia with various hypnotics in patients undergoing surgical procedures other than cardiac or brain surgery. We also aimed to test whether delayed postoperative cognitive recovery increases the risk of postoperative delirium. Methods/Design After local ethics committee approval, enrolled patients will be randomly assigned to one of three treatment groups. In all patients anaesthesia will be induced with propofol and fentanyl, and maintained with the anaesthetics desflurane, or sevoflurane, or propofol and the analgesic opioid fentanyl. The onset of postoperative delirium will be monitored with the Nursing Delirium Scale every three hours up to 72 hours post anaesthesia. Cognitive function will be evaluated with two cognitive test batteries (the Short Memory Orientation Memory Concentration Test and the Rancho Los Amigos Scale) preoperatively, at baseline, and postoperatively at 20, 40 and 60 min after extubation. Statistical analysis will investigate differences in the hypnotics used to maintain anaesthesia and the odds ratios for postoperative delirium, the relation of early postoperative cognitive recovery and postoperative delirium rate. A subgroup analysis will be used to categorize patients according to demographic variables relevant to the risk of postoperative delirium (age, sex, body weight) and to the preoperative score index

    The Conseal plug was evaluated in a four week period among 30 consecutive colostomy patients. The clinical trial, a multicenter study covering 11 Danish Hospitals, was started five to 12 days postoperatively among motivated patients in good physical condition. Twenty patients (67%) completed the trial. Ten patients (33%) gave up because of wound infection, leakage, extrusion of the foam part or fault in the test procedure. At the end of the trial all 20 patients wanted to continue using the plug and 84% were still using the Conseal system six months later. We conclude that the plug is well tolerated among motivated patients less than a week postoperatively and that the Conseal plug is a good alternative to the colostomy bag early in the postoperative course.

    ABSTRACT Objective: To investigate the early postoperative complications in two different tube ligation methods during the first 3 months in Baerveldt implant surgery. Participants: This study involved 157 eyes from 144 patients who underwent Baerveldt Implant Surgery at the Japanese Red Cross Medical Center, Tokyo, Japan. Methods: Pre- and postoperative intraocular pressure (IOP), combined surgery, postoperative time-point of tube ligation release, and postoperative complications in two different tube ligation methods [absorbable ligation method using 8-0 polyglactin suture (group A) and nonabsorbable ligation method using 7-0 nylon suture (group B)] were retrospectively reviewed. Results: After excluding eyes that had undergone combined trabeculectomy (26 eyes) and vitrectomy (2 eyes), eyes with previous tube surgery (22 eyes), and eyes that had undergone the stent method (1 eye), 30 of 28 patients in group A and 71 eyes of 71 patients in group B were found to fit the criteria of this study. The rate of successful surgical outcome was 80% in group A and 74.6% in group B (p = 0.705). During the 3 months postoperative, high IOP tended to occur more often in group B (67.6%) than in group A (46.7%) (p = 0.073), and ciliochoroidal detachment tended to occur more often in group A (10.0%) than group B (2.8%) (p = 0.154). Conclusion: The results of this study show that both ligation methods are effective, however, the selection of tube ligation method should be done in accordance with the different method-specific risks to which may occur.

    Abstract Background: The administration of oral pregabalin preoperatively has been reported to reduce acute postoperative pain. However, no clinical study to date has yet fully investigated whether or not pregabalin premedication affects sensory and motor blocks using spinal anesthesia and its effect upon early postoperative pain management. This prospective, randomized, and double-blind clinical study was designed to evaluate the efficacy of a single dose of pregabalin in terms of spinal blockade duration and its potential opioid-sparing effect during the first 24 hours subsequent to urogenital surgery. Methods: Forty-four patients scheduled for urogenital surgery under spinal anesthesia were randomly allocated to 2 groups: group C (no premedication; orally administered placebo 2 hours before surgery) and group P (orally administered 150 mg pregabalin 2 hours before surgery). Results: The duration of sensory and motor blockade was significantly prolonged in group P patients when compared with that in group C patients, and the pain scores at postoperative 6 and 24 hours were significantly lower in group P patients. Requests for analgesics during the first postoperative 24 hours were lower among group P patients. Conclusion: Premedication with a single dose of 150 mg pregabalin before surgery promoted the efficacy of intrathecal bupivacaine and improved postoperative analgesia in patients undergoing urogenital surgery under spinal anesthesia.

    Hip fractures are the most serious consequence of falling in older people with osteoporosis. Early ambulation is one of the main goals of inpatient rehabilitation aimed at reducing negative effects of immobilization, and promoting functional recovery. Recognizing the role of different factors that are associated with time to ambulation time after hip fracture surgery may help decrease morbidity and mortality rates. The aim of this study was to examine the impact of postoperative pain time to ambulation following hip fracture surgery. A total of 96 patients who consecutively presented at the Clinic for Orthopaedic Surgery and Traumatology, Clinical Center Serbia during a 6 month period were included in the study. Subjects were assessed regarding socioedemographic characteristics, prefracture functional status, cognitive status, general health status, fracture type, type of anaesthesia, and waiting time for surgery. The VAS scale (0-100) was used to measure pain intensity on the first postoperative day. Our results revealed that patients, whose time to ambulation was = 48 h postoperatively were of worse physical health, and had significantly higher VAS score on the first postoperative day. Unrelieved pain in geriatric hip fracture patients is associated with delayed ambulation. Future research should confirm the posi-tive effects of aggressive pain management programs on early functional outcome in elderly patients who sustain hip fractures.

    Management of postoperative pain has been shown to be inadequately controlled, and, in fact, can have significant deleterious effects on a patient's early postoperative recovery. Continuous epidural analgesia has recently been used to control postoperative pain. This mode of analgesia controls postoperative pain without the delays inherent in the PRN administration of systemic narcotics. This was a multidisciplinary, prospective, randomized, double-blind study of various epidural analgesic agents in 53 thoracic and 81 abdominal surgery patients. The focus of the study was to identify the benefits and problems of continuous epidural analgesia for postoperative pain management and the implications for the nursing care of the patients. Evaluation of the effectiveness of the analgesia was based on the following measures: (1) pain measured at regular intervals in the 72-hour period with a visual analog; (2) pain as measured after 72 hours with the word descriptor section of the McGill Pain Questionnaire; (3) amount of supplemental systemic narcotic analgesic needed; (4) recovery of ambulatory and respiratory function, including ability to perform coughing and deep-breathing exercises; (5) occurrence of adverse effects; and (6) the type and distribution of nursing care problems associated with continuous epidural infusions. The results of this study showed that the level of pain relief and recovery of postoperative function was superior to that provided by the more widely used (PRN) systemic administration of narcotics. With the exception of the report of back pain by patients receiving the normal saline epidural solution, complications did not occur in a significantly greater proportion when using the epidural route. Although some nursing care problems were identified, patients who received epidural analgesia were able to be cared for on general care units with no adverse effects reported. PMID:2285719

    It is already a textbook item that in patients with prostatic cancer stage T1-T2 N0M0 radical prostatectomy is the only curative treatment. Radical prostatectomy is indicated also for patients in stage T3 N0M0 who underwent antiandrogenic (Fugerel) treatment for 3 months with the aim of reducing tumour volume. In the following 35 cases will be scrutinized, with special regard to preoperative staging and early postoperative complications.

    Mastoid effusion is a poorly understood complication after craniotomy. The incidence and severity of postoperative mastoid effusion were retrospectively examined on postoperative magnetic resonance (MR) images to assess any association with craniotomy procedures, time course, and neuro-otological complications. We evaluated the early postoperative MR images (within 4 days of craniotomy) and medical records of 74 patients who underwent 77 operations for the treatment of various intracranial diseases from January 2000 to December 2001. Mastoid effusion was classified into four grades: none, partial, moderate, and severe diffuse effusion in the mastoid air cells. Thirty-three follow-up MR images from 26 patients were also reviewed. Postoperative mastoid effusion occurred ipsilateral to the craniotomy site in 62 cases and contralateral in 56 cases. Mastoid effusion was significantly more severe ipsilateral than contralateral to craniotomy with exposure of the mastoid air cells ( P<0.0001). There was no significant difference in severity between the contralateral and ipsilateral sides after craniotomy without mastoid air cell opening ( P=0.437). Mastoid effusion following craniotomy without exposure of mastoid air cells resolved within 3 months. However, otitis media with effusion developed in six patients with severe mastoid effusion ipsilateral to craniotomy with exposure of the mastoid air cells. Mastoid effusion frequently developed on both sides. Any grade of mastoid effusion on the ipsilateral side to craniotomy without exposure of mastoid air cells, or on the contralateral side, was asymptomatic or had a benign course, and disappeared within 3 months.

    We explored the effects of flurbiprofen axetil on interleukin (IL)-2 and IL-6 levels in postoperative patients with colorectal cancer. A total of 120 patients (American Society of Anesthesiologists I and II) scheduled to undergo colorectal cancer surgery were randomly divided into 3 groups (N = 40 in each group): flurbiprofen axetil group (group F), morphine group (group M), and tramadol group (group T). Group M received 0.1 mg/kg morphine, group T received 1.5 mg/kg tramadol, and group F received 1.5 mg/kg flurbiprofen axetil. Patients in the 3 groups were administered treatments through intravenous injection 10 min before surgery. Serum IL-2 and IL-6 levels were detected. Postoperative adverse reactions were recorded, such as nausea, vomiting, and pruritus. The serum IL-6 level of the 3 groups increased 3 h after surgery. Compared with group M, IL-6 level was higher in group T and group F at 1 day after the surgery, and the differences between group M and the other groups were significant (P < 0.05). Moreover, the incidence of adverse reactions was significantly different among 3 groups (P < 0.05). Flurbiprofen axetil promoted the secretion of IL-2 and inhibited IL-6; additionally, flurbiprofen axetil may have a lower incidence of adverse reactions compared to other treatments.

    Background Bone scintigraphy was performed to monitor anastomotic patency and bone viability. Methods In this retrospective study, bone scans were carried out during the first three postoperative days in a series of 60 patients who underwent microvascular bone grafting for reconstruction of the mandible or maxilla. Results In our series, early bone scans detected a compromised vascular supply to the bone with high accuracy (p < 10-6) and a sensitivity that was superior to the sensitivity of clinical monitoring (92% and 75% respectively). Conclusion When performing bone scintigraphy during the first three postoperative days, it not only helps to detect complications with high accuracy, as described in earlier studies, but it is also an additional reliable monitoring tool to decide whether or not microvascular revision surgery should be performed. Bone scans were especially useful in buried free flaps where early postoperative monitoring depended exclusively on scans. According to our experience, we recommend bone scans as soon as possible after surgery and immediately in cases suspicious of vascularized bone graft failure. PMID:17448223

    We studied 37 children soon after ureteroneocystostomy using diuretic radionuclide urography to assess the patency of the ureterovesical junction. Postoperative obstruction was excluded correctly in 90 per cent of the patients. Transient ureterovesical obstruction occurred in 5 patients, identification of which was useful in assigning risk and in guiding followup studies. Because it is a safe, noninvasive and relatively low radiation test the diuretic radionuclide urogram proves to be an attractive alternative to the excretory urogram in the early and late followup of patients undergoing a ureterovesical junction operation.

    Surgical treatment of patients with aortic valve disease and concomitant mitral insufficiency remains debatable. We analyzed early postoperative results of surgical treatment of 80 patients depending on type of surgery. All patients were divided into three groups: the 1st - aortic valve replacement in patients without mitral valve dysfunction (control group) (n=44); the 2nd - isolated aortic valve replacement in patients with concomitant mitral regurgitation degree 2-3 (n=18), the 3rd - simultaneous aortic and mitral valve replacement (n=18). Combined valve replacement was associated with more intraoperative blood loss (852.78±442.08 ml) compared with aortic valve replacement (658.7±374.09 ml), p<0.05. In patients with mitral regurgitation greater hematocrit decrease was observed (22.13±3.6% in group 2 and 21.4±4.48 in group 3) in comparison with control group (24.17±3.72% in group 1), p<0.05. Incidence of postoperative complications did not differ in all groups. Mortality rate was 6.8% in group 1 and 11.1% in group 3, there were no deaths in group 2. Both valves correction provided faster myocardial remodeling. Left ventricular end-diastolic volume decreased on 50 ml in group 3, on 33.67 ml in group 2 and on 50.73 ml in group 1 (p<0.05). Pulmonary pressure decreased on 20 mm Hg in group 3, on 13 mm Hg - in group 2 and on 12.57 mm Hg - in group 1, p<0.05. In groups 1 and 3 pulmonary pressure became normal after operation, in group 2 signs of pulmonary hypertension were observed (pressure - 35.3 mm Hg). Analysis of the results showed that simultaneous mitral and aortic valves replacement initiates normalization of intracardiac hemodynamics in early postoperative period. PMID:26081181

    Background and Objectives: Adequate nutritional supplementation in infants with cardiac malformations after surgical repair is a challenge. Critically ill infants in the early postoperative period are in a catabolic stress. The mismatch between estimated energy requirement (EER) and the intake in the postoperative period is multifactorial, predisposing them to complications such as immune deficiency, more infection, and growth failure. This study aimed to assess the feasibility and efficacy of enriched breast milk feed on postoperative recovery and growth of infants after open heart surgery. Methodology: Fifty infants <6 months of age were prospectively randomized in the trial for enteral nutrition (EN) postoperatively from day 1 to 10, after obtaining the Institute Ethics Committee's approval. They were equally divided into two groups on the basis of the feed they received: Control group was fed with expressed breast milk (EBM; 0.65 kcal/ml) and intervention group was fed with EBM + energy supplementation/fortification with human milk fortifier (7.5 kcal/2 g)/Simyl medium-chain triglyceride oil (7.8 kcal/ml). Energy need for each infant was calculated as per EER at 90 kcal/kg/day, as the target requirement. The intra- and post-operative variables such as cardiopulmonary bypass and aortic cross-clamp times, ventilation duration, Intensive Care Unit (ICU), and hospital length of stay and mortality were recorded. Anthropometric and hematological parameters and infection control data were recorded in a predesigned pro forma. Data were analyzed using Stata 14.1 software. Results: The duration of mechanical ventilation, length of ICU stay (LOIS), length of hospital stay (LOHS), infection rate, and mortality rate were lower in the intervention group compared to the control group although none of the differences were statistically significant. Infants in control group needed mechanical ventilation for about a day more (i.e., 153.6 ± 149.0 h vs. 123.2 ± 107.0 h; P = 0

    The Sonoma CRx device (Sonoma Orthopedic Products, Santa Rosa, California) is a recently introduced intramedullary device with a flexible shaft that becomes rigid once actuated to allow deployment within the sigmoidal contour of the clavicular shaft. Medial intramedullary cortical purchase is obtained by grippers and lateral purchase through a locking bicortical buttressing screw. This article describes 2 cases of early hardware failure using this device. In both cases, early postoperative radiographs demonstrate adequate initial fracture reduction and implant position. Both patients sustained repeat injuries, one under low physiologic load and the other after returning to mixed martial arts 4 months postoperatively. Implant failure was noted after reinjury in both cases. Complete healing and full return to function was documented for both patients at 2 years. Proper patient selection and counseling regarding the limitations of this intramedullary fixation device are important. Biomechanical comparison of this implant to plate fixation under physiologic loads of combined axial compression and torsion may shed light on differences in fixation stability. PMID:24200452

    We examined colon cancer patients who received soluble dietary fiber enteral nutrition (SDFEN) to evaluate the feasibility and potential benefit of early SDFEN compared to EN. Sixty patients who were confirmed as having colon cancer with histologically and accepted radical resection of colon cancer were randomized into an SDFEN group and an EN group. The postoperative complications, length of hospital stay (LOH), days for first fecal passage, and the difference in nutritional status, immune function and inflammatory reaction between pre-operation and post-operation were all recorded. The statistical analyses were performed using the t-test and the chi square test. Statistical significance was defined as p < 0.05. After the nutrition support, differences in the levels of albumin, prealbumin and transferrin in each group were not statistically significant (p > 0.05); the levels of CD4+, IgA and IgM in the SDFEN group were higher than that of the EN group at seven days (p < 0.05); the levels of TNF-α and IL-6 in the SDFEN group were lower than that of the EN group at seven days (p < 0.05); and patients in the SDFEN group had a significantly shorter first flatus time than the EN group (p < 0.05). Early post-operative SDFEN used in colon cancer patients was feasible and beneficial in immune function and reducing inflammatory reaction, gastrointestinal function and speeding up the recovery.

    The modified diet of postoperative rehabilitation program in elderly patients with gastroduodenal ulcers and prognosis of development of protein-energy malnutrition (PEM) is presented. It is shown that early initiated special diet in postoperative period, blocks mechanisms of malnutrition and can significantly improve the functional status of the small intestine and activate, thus, membrane digestion, which leads to normalization of all types of metabolism in elderly patients. In comparison with control group, where 72% of patients in postoperative period had malnutrition, malnutrition in the study group revealed a mild degree in only 17.3% of patients.

    AIM: To investigate the effect of somatostatin and dexamethasone on early postoperative small bowel obstruction with obliterative peritonitis (EPSBO-OP). METHODS: This prospective randomized study included 70 patients diagnosed with EPSBO-OP from June 2002 to January 2009. Patients were randomized into two groups: a control group received total parenteral nutrition and nasogastric (NG) tube feeding; and an intervention group received, in addition, somatostatin and dexamethasone treatment. The primary endpoints were time to resolution of bowel obstruction and length of hospital stay, and the secondary endpoints were daily NG output and NG feeding duration, treatment-related complications, postoperative obstruction relapse, and patient satisfaction. RESULTS: Thirty-six patients were allocated to the intervention group and 34 to the control group. No patient needed to undergo surgery. Patients in the intervention group had an earlier resolution of bowel obstruction (22.4 ± 9.1 vs 29.9 ± 10.1 d, P = 0.002). Lower daily NG output (583 ± 208 vs 922 ± 399 mL/d, P < 0.001), shorter duration of NG tube use (16.7 ± 8.8 vs 27.7 ± 9.9 d, P < 0.001), and shorter length of hospital stay (25.8 vs 34.9 d, P = 0.001) were observed in the intervention group. The rate of treatment-related complications (P = 0.770) and relapse of obstruction (P = 0.357) were comparable between the two groups. There were no significant differences in postoperative satisfaction at 1, 2 and 3 years between the two groups.

  7. A rabbit osteomyelitis model for the longitudinal assessment of early post-operative implant infections

    PubMed Central

    2013-01-01

    Background Implant infection is one of the most severe complications within the field of orthopaedic surgery, associated with an enormous burden for the healthcare system. During the last decades, attempts have been made to lower the incidence of implant-related infections. In the case of cemented prostheses, the use of antibiotic-containing bone cement can be effective. However, in the case of non-cemented prostheses, osteosynthesis and spinal surgery, local antibacterial prophylaxis is not a standard procedure. For the development of implant coatings with antibacterial properties, there is a need for a reliable animal model to evaluate the preventive capacity of such coatings during a specific period of time. Existing animal models generally present a limited follow-up, with a limited number of outcome parameters and relatively large animal numbers in multiple groups. Methods To represent an early post-operative implant infection, we established an acute tibial intramedullary nail infection model in rabbits by contamination of the tibial nail with 3.8 × 105 colony forming units of Staphylococcus aureus. Clinical, haematological and radiological parameters for infection were weekly assessed during a 6-week follow-up with post-mortem bacteriological and histological analyses. Results S. aureus implant infection was confirmed by the above parameters. A saline control group did not develop osteomyelitis. By combining the clinical, haematological, radiological, bacteriological and histological data collected during the experimental follow-up, we were able to differentiate between the control and the infected condition and assess the severity of the infection at sequential timepoints in a parameter-dependent fashion. Conclusion We herein present an acute early post-operative rabbit implant infection model which, in contrast to previously published models, combines improved in-time insight into the development of an implant osteomyelitis with a relatively low

    Introduction: Urinary tract infection (UTI) is one of the most common bacterial infections in children that can be associated with renal parenchymal injuries and late scars. Dimercaptosuccinic acid (DMSA) renal scan is known as golden standard for detecting acute pyelonephritis (APN) that has a lot of difficulties and limitations. Objectives: we designed this study the accuracy of one inflammatory marker, serum procalcitonin (PCT) to identify as an early predictor of renal injuries. Patients and Methods: A prospective study was carried out in 95 patients who admitted in the hospital with the first febrile UTI. Serum PCT of all patients was measured; sensitivity, specificity, positive and negative predictive value (PPV and NPV) of this marker was analyzed compared to DMSA scan. P value <0.05 was taken as significant. Results: In total, 79 females and 16 males were investigated. There are 42 cases in group 1 with normal DMSA scan and 53 patients in group two with renal parenchymal injuries in their scans. Mann-Whitney test showed a meaningful relation between the two groups regarding PCT level (P<0.0001). Sensitivity, specificity, PPV and NPV of PCT reported in optimum cut off were 70%, 88.1%, 88.1% and 70%, respectively. The positive likelihood ratio (PLR) of PCT test was 5.8. Conclusion: In the current survey, PCT was the eligible inflammatory marker to predict renal parenchymal injuries in children with proper sensitivity, specificity, PPV and NPV that play also a pivotal role in the children aged less than 24 months, although, more studies should be undertaken to confirm.

    Objective To assess the role of preoperative and postoperative serum C-reactive protein (CRP) level on the prediction of pregnancy outcomes following ultrasound-indicated cerclage (UIC). Methods We retrospectively reviewed the medical records 44 women who underwent UIC between January 2011 and December 2011. UIC was performed between 14 and 24 weeks of gestation in women with short cervix. We divided UIC patients into two groups according to the gestational age at delivery (34 weeks) and compared the two groups. Group A was defined as patients who delivered ≥34 weeks of gestation, and group B as patients delivered <34 weeks. Correlation and receiver-operating characteristic curves were also analyzed for the prediction of preterm birth after UIC. Results Thirty women delivered ≥34 weeks (group A) and 14 women delivered <34 weeks (group B). Pre- and post-cerclage CRP were significantly lower in group A (pre-cerclage CRP, 1.1±1.0 vs. 11.4±6.2 mg/dL, P<0.001; post-cerclage CRP, 0.6±0.5 vs. 7.4±7.2 mg/dL, P<0.001). The mean gestational age at delivery in group A was 37.7±1.8 weeks and that in group B was 26.9±4.3 weeks (P<0.001). There were significant negative correlations between pre- and post-cerclage CRP and latency from UIC to delivery (r=-0.82, P<0.001; r=-0.70, P<0.001, respectively). Conclusion Both pre- and post-cerclage CRP were useful in predicting the preterm birth following UIC. PMID:27004199

    Various clinical trials have assessed how intraoperative anesthetics can affect early recovery, hemodynamics and nociception after supratentorial craniotomy. Whether or not the difference in recovery pattern differs in a meaningful way with anesthetic choice is controversial. This review examines and compares different anesthetics with respect to wake-up time, hemodynamics, respiration, cognitive recovery, pain, nausea and vomiting, and shivering. When comparing inhalational anesthetics to intravenous anesthetics, either regimen produces similar recovery results. Newer shorter acting agents accelerate the process of emergence and extubation. A balanced inhalational/intravenous anesthetic could be desirable for patients with normal intracranial pressure, while total intravenous anesthesia could be beneficial for patients with elevated intracranial pressure. Comparison of inhalational anesthetics shows all appropriate for rapid emergence, decreasing time to extubation, and cognitive recovery. Comparison of opioids demonstrates similar awakening and extubation time if the infusion of longer acting opioids was ended at the appropriate time. Administration of local anesthetics into the skin, and addition of corticosteroids, NSAIDs, COX-2 inhibitors, and PCA therapy postoperatively provided superior analgesia. It is also important to emphasize the possibility of long-term effects of anesthetics on cognitive function. More research is warranted to develop best practices strategies for the future that are evidence-based. PMID:26345202

    Background and purpose — A criticism of total hip arthroplasty (THA) survivorship analysis is that revisions are a late and rare outcome. We investigated whether prolonged opioid use is a possible indicator of early THA failure. Patients and methods — We conducted a cohort study of THAs registered in a total joint replacement registry from January 2008 to December 2011. 12,859 patients were evaluated. The median age was 67 years and 58% were women. Opioid use in the year after surgery was the exposure of interest, and the cumulative daily amounts of oral morphine equivalents (OMEs) were calculated. Post-THA OMEs per 90 day periods were categorized into quartiles. The endpoints were 1- and 5-year revisions. Results — After the first 90 days, 27% continued to use opioids. The revision rate was 0.9% within a year and 1.7% within 5 years. Use of medium-low (100–219 mg), medium-high (220–533 mg), and high (≥ 534 mg) amounts of OMEs in days 91–180 after surgery was associated with a 6 times (95% confidence interval (CI): 3–15), 5 times (CI: 2–13), and 11 times (CI: 2.9–44) higher adjusted risk of 1 year revision, respectively. The use of medium-low and medium-high amounts of OMEs in days 181–270 after surgery was associated with a 17 times (CI: 6–44) and 14 times (95% CI: 4–46) higher adjusted risk of 1-year revision. There was a similar higher risk of 5-year revision. Interpretation — Persistent postoperative use of opioids was associated with revision THA surgery in this cohort, and it may be an early indicator of potential surgical failures. PMID:27168377

    This study aimed to determine early postoperative changes of LDL/HDL subfraction profile and HDL-associated enzymes following laparoscopic sleeve gastrectomy (LSG). Thirteen obese patients (mean body mass index (BMI) 52.74 ± 10.97 kg/m(2)) underwent LSG and normal weight control patients (mean BMI 23.56 ± 1.92 kg/m(2)) underwent laparoscopic abdominal surgery. Fasting blood samples were collected prior to surgery, at day 1 after surgery, and after postoperation oral feeding. LDL and HDL subfraction analysis was done by continuous disk polyacrylamide gel electrophoresis. Plasma levels of cholesteryl ester transfer protein (CETP), lecithin-cholesterol acyltransferase (LCAT), and apolipoprotein A-1 (apoA-I) were determined by enzyme-linked immunosorbent assay. Measurement of CETP and LCAT activity was performed via fluorometric analysis. LDL subfraction profile showed no change in both LSG and control group patients. No significant difference was observed in HDL cholesterol, HDL-subfraction distribution, and apoA-I levels in the control group. LSG patients showed a significant increase in HDL-large and a significant decrease in HDL-small fractions at postoperation day 1 compared to preoperation. HDL cholesterol significantly decreased and apoA-I significantly increased in LSG patients after postoperation oral feeding compared to both preoperation and postoperation day 1. Changes in HDL subfraction profile at postoperation day 1 after LSG were accompanied by a significant decrease in CETP protein, LCAT protein, and LCAT activity as compared to preoperation levels. Early changes in HDL subfraction profile and HDL-associated enzymes following LSG suggest that the surgical procedure, irrespective of changes in body weight, affects reverse cholesterol transport.

    Purpose To report dosimetry and early toxicity data in breast cancer patients treated with postoperative proton radiation therapy. Methods and Materials From March 2013 to April 2014, 30 patients with nonmetastatic breast cancer and no history of prior radiation were treated with proton therapy at a single proton center. Patient characteristics and dosimetry were obtained through chart review. Patients were seen weekly while on treatment, at 1 month after radiation therapy completion, and at 3- to 6-month intervals thereafter. Toxicity was scored using Common Terminology Criteria for Adverse Events version 4.0. Frequencies of toxicities were tabulated. Results Median dose delivered was 50.4 Gy (relative biological equivalent [RBE]) in 5 weeks. Target volumes included the breast/chest wall and regional lymph nodes including the internal mammary lymph nodes (in 93%). No patients required a treatment break. Among patients with >3 months of follow-up (n = 28), grade 2 dermatitis occurred in 20 patients (71.4%), with 8 (28.6%) experiencing moist desquamation. Grade 2 esophagitis occurred in 8 patients (28.6%). Grade 3 reconstructive complications occurred in 1 patient. The median planning target volume V95 was 96.43% (range, 79.39%-99.60%). The median mean heart dose was 0.88 Gy (RBE) [range, 0.01–3.20 Gy (RBE)] for all patients, and 1.00 Gy (RBE) among patients with left-sided tumors. The median V20 of the ipsilateral lung was 16.50% (range, 6.1%–30.3%). The median contralateral lung V5 was 0.34% (range, 0%–5.30%). The median maximal point dose to the esophagus was 45.65 Gy (RBE) [range, 0–65.4 Gy (RBE)]. The median contralateral breast mean dose was 0.29 Gy (RBE) [range, 0.03–3.50 Gy (RBE)]. Conclusions Postoperative proton therapy is well tolerated, with acceptable rates of skin toxicity. Proton therapy favorably spares normal tissue without compromising target coverage.

    The present study sought to characterize the role of macrophage inflammatory protein-3α (MIP-3α) in non-small cell lung cancer (NSCLC) patients with early recurrence or metastasis after primary pulmonary resection. Follow-up examinations were conducted for 203 NSCLC patients with primary pulmonary resection for two years post-operatively, and data was also collected for 20 healthy subjects. Serum MIP-3α levels were determined prior to surgery and at post-operative days (PODs) 30, 90 and 180, and the relevant clinical and operative variables were collected. Serum MIP-3α was measured using a commercially available enzyme-linked immunosorbent assay. There were no significant differences in age, gender and histological type among all groups (P>0.05). Serum MIP-3α levels on POD 180 were significantly higher in the recurrence group than in the non-recurrence group and healthy subjects (P=0.001). There was no significant difference in the serum MIP-3α level at PODs 90 and 180 in the patients with or without adjuvant chemotherapy (P>0.05). The recurrence rate in the high serum MIP-3α level group was 41.67%, much higher than the 23.53% observed in the low level group (P=0.006). The patients with high serum levels of MIP-3α had a significantly shorter overall recurrence-free time compared with those with low levels (P=0.004). Multivariate Cox's regression analyses showed that only serum MIP-3α level was significant, with a hazard ratio of 1.061, a 95% confidence interval of 1.044-1.078 and a P-value of 0.001. The serum MIP-3α level in the patients with liver and bone metastases were remarkably higher than those with recurrence at other sites. The high post-operative serum MIP-3α levels were associated with an increased risk of post-operative early recurrence or metastasis in the lung cancer patients, specifically in those with bone or liver metastases.

    The benefits of early enteral feeding (EEN) have been demonstrated in gastrointestinal surgery. But, the impact of EEN has not been elucidated yet. We assessed the postoperative nutritional status of patients who had undergone pancreaticoduodenectomy (PD) according to the postoperative nutritional method and compared the clinical outcomes of two methods. A prospective randomized trial was undertaken following PD. Patients were randomly divided into two groups; the EEN group received the postoperative enteral feed and the control group received the postoperative total parenteral nutrition (TPN) management. Thirty-eight patients were included in our analyses. The first day of bowel movement and time to take a normal soft diet was significantly shorter in EEN group than in TPN group. Prealbumin and transferrin were significantly reduced on post-operative day (POD) 7 and were slowly recovered until POD 90 in the TPN group than in the EEN group. EEN group rapidly recovered weight after POD 21 whereas it was gradually decreased in TPN group until POD 90. EEN after PD is associated with preservation of weight compared with TPN and impact on recovery of digestive function after PD. PMID:22379336

    Prevention and treatment of postoperative pain, nausea and vomiting continues to be a major challenge in postoperative care. This study was designed to compare the effects of small dose of oral gabapentin with placebo as premedication on early postoperative pain, nausea and vomiting in patients undergoing ambulatory laparoscopic surgery for Assisted Reproductive Technologies (ART). Seventy women undergoing ambulatory laparoscopic surgery were randomly assigned to receive oral gabapentin 300 mg or placebo as premedication 1 h before surgery. Patients were anesthetized with the same anesthetic techniques. Duration of anesthesia, severity of postoperative pain and presence of Post Operative Nausea and Vomiting (PONV) were compared between the study groups. Demographic data and the duration of anesthesia were not statistically different between the study groups. There were significant differences in median VAS scores (25th-75th) measurements at all time points in the study groups (p < 0.05). Ten patients (28%) in control and one patient (0.02%) in gabapentin group required additional IV analgesic that was statistically significant (p = 0.012). Two patients in gabapentin and nine patients in placebo group had nausea (p = 0.022). None of patients in gabapentin but four patients in placebo group had vomiting (p = 0.114). Administration of oral gabapentin 300 mg before ambulatory laparoscopic surgeries, decreased postoperative pain, analgesic requirement and nausea.

    Hemorrhoidectomy is used for the surgical treatment of high-grade hemorrhoids. The most prominent complaint after hemorrhoidectomy is pain. Postoperative pain management is still a big problem after surgery in patients with hemorrhoidectomy. The aim of the study was to assess the effect of early application of warm bag on postoperative pain after hemorrhoidectomy. All patients were randomly divided into warm plastic bag and control groups by using sealed envelopes, which were prepared preoperatively. After standard spinal anesthesia, all patients underwent standard Milligan-Morgan hemorrhoidectomy using Ligasure™. Although the study group received the warm bag application, the control group did not receive such a treatment. Two separate visual analog scale (VAS) measurements were performed for postoperative pain assessments on postoperative days, one during the resting state and the other one during the straining phase after the onset of peristaltic bowel movement. Postoperative VAS scores were significantly lower among the warm plastic bag group as compared with the control group on Days 1 and 3 for the resting state and on Day 3 for defecation. Additionally, a significant difference existed between the two groups in terms of the need for additional anesthesia. Local thermal application appears to be a safe and effective method for pain relief after hemorrhoidectomy.

    Abstract Hypoalbuminemia has been reported to be an independent risk factor for acute kidney injury (AKI). However, little is known about the relationship between the albumin level and the incidence of AKI in patients undergoing total knee arthroplasty (TKA). The aim of our study was to assess incidence and risk factors for AKI and to evaluate the relationship between albumin level and AKI following TKA. The study included a retrospective review of medical records of 1309 consecutive patients who underwent TKA between January 2008 and December 2014. The patients were divided into 2 groups according to the lowest serum albumin level within 2 postoperative days (POD2_alb level < 3.0 g/dL vs ≥3.0 g/dL). Multivariate logistic regression analysis was used to assess risk factors for AKI. A comparison of incidence of AKI, hospital stay, and overall mortality in the 2 groups was performed using propensity score analysis. Of 1309 patients, 57 (4.4%) developed AKI based on Kidney Disease Improving Global Outcomes criteria. Factors associated with AKI included age (odds ratio [OR] 1.05; 95% confidence interval [CI] 1.01–1.09; P = 0.030), diabetes (OR 3.12; 95% CI 1.65–5.89; P < 0.001), uric acid (OR 1.51; 95% CI 1.26–1.82; P < 0.001), beta blocker use (OR 2.65; 95% CI 1.48–4.73; P = 0.001), diuretics (OR 16.42; 95% CI 3.08–87.68; P = 0.001), and POD2_alb level < 3.0 g/dL (OR 1.92; 95% CI 1.09–3.37; P = 0.023). After propensity score analysis, POD2_alb level<3.0 g/dL was associated with AKI occurrence (OR 1.82; 95% CI 1.03–3.24, P = 0.041) and longer hospital stay (P = 0.001). In this study, we demonstrated that POD2_alb level<3.0 g/dL was an independent risk factor for AKI and lengthened hospital stay in patients undergoing TKA. PMID:27495094

    Background Until date, there are no clear recommendations for regular perioperative measurements of serum CEA levels for lung cancer in any guidelines. The purpose in the present study is to evaluate the prognostic significance of perioperative serum carcinoembryonic antigen (CEA) levels in patients with pathological-stage I non-small cell lung cancer (NSCLC). Methods We retrospectively reviewed 263 completely resected pathological-stage I NSCLC patients whose preoperative and postoperative serum CEA levels were measured. Patients were subdivided according to the perioperative change of CEA levels: continuously normal CEA levels (NN group), continuously high CEA levels (HH group), and high preoperative CEA levels that returned to normal levels post-operation (HN group). The clinicopathological factors and overall survival (OS) among these 3 groups were compared. Univariate and multivariate analyses of the correlation between clinicopathological factors and OS were performed. Results High preoperative CEA levels significantly correlated with men aged >70 years with smoking history, high serum CYFRA 21–1 levels, greater tumor diameter, presence of visceral pleural invasion (VPI), and moderate-to-poor differentiation. Five-year OS rates in the NN and HH groups were 95.5% and 59.3%, respectively. Four-year OS rate in the HN group was 85.5%. Multivariate analyses indicated tumor diameter of more than 30 mm, presence of VPI, and the HH group were independent unfavorable prognostic factors. Conclusions A high postoperative CEA level was an independent unfavorable prognostic factor in pathological-stage I NSCLC patients. Patients with high postoperative CEA levels may benefit from adjuvant chemotherapy. PMID:23607757

    Our objective was to evaluate the effects of postoperative xylitol gum chewing on gastrointestinal functional recovery after laparoscopy. Altogether, 120 patients undergoing elective gynecologic laparoscopy were randomly divided into 2 groups of 60 each (final numbers: 53 controls, 56 patients). Controls underwent a routine postoperative regimen. Starting 6 hour after surgery, study patients chewed mint-flavored, sugarless xylitol gum until flatus occurred thrice a day. Other postoperative management was routine. First bowel sounds, first flatus, first bowel movement, and discharge times were recorded. Symptoms included abdominal distension, nausea, and vomiting. First flatus and first bowel sounds occurred significantly (P<0.001) earlier in the study patients. No significant differences were found for first defecation time, hospitalization duration, or mild/severe intestinal obstruction (all P>0.05). Thus, xylitol gum chewing after laparoscopy can effectively shorten the time to first flatus and helps with postoperative gastrointestinal functional recovery. It is simple, convenient, and well tolerated. PMID:26121546

    Context: Frequent incidence of early postoperative memory impairment (POMI) after cardiac surgery remains a concern because of associated morbidity, impaired quality of life, and increased health care cost. Aim: To assess the effect of preoperative statin therapy on POMI in patients undergoing off-pump coronary artery bypass (OPCAB) surgery. Setting and Design: Prospective observational study in a tertiary level hospital. Methods: Sixty patients aged 45–65 years undergoing OPCAB surgery were allocated into two groups of 30 each. Group A patients were receiving statin and Group B patients were not receiving statins. All patients underwent memory function assessment preoperatively after admission to hospital and on the 6th postoperative day using postgraduate institute memory scale. Statistical Analysis: Appropriate tests were applied with SPSS 20 to compare both groups. The value P < 0.05 was considered statistically significant. Multiple regression analysis was performed with confounding factors to determine the effect on memory impairment. Results: Patients in Group A showed significant postoperative deterioration in 6 of the 10 functions and in Group B showed deterioration in 9 of 10 functions tested compared to preoperative scores. Intergroup comparison detected less POMI in Group A compared to Group B and was statistically significant in 8 memory functions. Multiple regression analysis detected statin as an independent factor in preventing memory impairment. Conclusions: Preoperative statin therapy attenuates the early POMI in patients undergoing OPCAB. Future long-term studies will define the efficacy of statin on POMI. PMID:26750672

    Abstract Background: Trial design neuroinflammation and postoperative pain after surgery are increasingly reported in association with postoperative cognitive dysfunction (POCD). Parecoxib, a selective cyclooxygenase (COX)-2 inhibitor, is used for postoperative analgesia for its potent anti-inflammatory and analgesic effects. This study aimed to evaluate parecoxib's effects on POCD in elderly patients undergoing total knee arthroplasty. Methods: Around 134 elderly patients undergoing total knee arthroplasty were randomly divided into parecoxib (group P) and control (group C) groups, and treated with parecoxib sodium and saline, respectively, shortly after induction of general anesthesia and 12-h postsurgery, respectively. Perioperative plasma IL-1β, IL-6, TNF-α, and C-reactive protein (CRP) 1evels were measured. Postoperative pain was assessed following surgery. Neuropsychological tests were performed before surgery, and 1 week and 3 months postoperation. Results: POCD incidence in group P was significantly lower compared with that of group C at 1 week after surgery (16.7% vs 33.9%; P < 0.05); no significant difference was found between groups C and P at 3-month follow-up (9.7% vs 6.7%). Compared with group C values, visual analog pain scale (VAS) scores at 3, 6, and 12 hours after surgery were significantly lower in group P(P < 0.05). Plasma IL-1β, IL-6, and TNF-α levels were lower in group P than in group C after the operation (P < 0.05). No significant difference in the plasma CRP level was found between groups P and C. Conclusions: Parecoxib sodium decreases POCD incidence after total knee arthroplasty in elderly patients and may explain how this drug suppresses inflammation and acute postoperative pain caused by surgical trauma.

    Most patients undergoing major aortic surgery have multiple comorbidities and are at high risk of postoperative complications that affect multiple organ systems. Different aortic pathologies and surgical repair techniques have specific impact on the postoperative course. Ischemia-reperfusion injury is the common denominator in aortic surgery and influences the integrity of end-organ function. Common postoperative problems include hemodynamic instability due to the immediate inflammatory response, renal impairment, spinal cord ischemia, respiratory failure with prolonged mechanical ventilation, and gastrointestinal symptoms such as ileus or mesenteric ischemia. Focused care bundles to establish homeostasis and a team working toward an early functional recovery determine the success of effective rehabilitation and outcomes after aortic surgery.

    Operational scars, especially those located on the exposed parts of the body, can be distressing. Despite high demand for an early intervention to minimize surgical scars, there is yet no universal consensus on optimal treatment. A split-scar, double-blind randomized controlled trial was held to assess the safety and efficacy of early postoperative botulinum toxin type A (BTA) injection in surgical scars. A single session of treatment was performed where BTA was allocated to one half of the scar and 0.9% saline to the control half. Scars were assessed using the modified Stony Brook Scar Evaluation Scale (SBSES) with standardized photographs. Fifteen patients completed the study, and their data were analyzed. At 6 months' follow-up, a significant improvement in SBSES score was noted for the BTA-treated halves of the scars (p < 0.001), with minimal change on the saline-treated side (p = 0.785). The mean calculated difference in SBSES scores (final/initial) between the BTA-treated side and the saline-treated side was also significant (p < 0.001). Early postoperative BTA injection was safe and effective in modulating thyroidectomy scars and may be a promising option for scar prevention.

    Percutaneous transluminal angioplasty has been successfully used for the treatment of transplant renal artery stenosis (RAS). Cutting-balloon angioplasty (CBA) is being used as a second option in pressure-resistant stenosis. It is thought that CBA is less traumatic and therefore restenosis occurs less frequently than in conventional angioplasty. This case report describes the unusual use of a cutting balloon in transplant RAS as a first option in the early postoperative period. Long-term follow-up data are also presented.

    Distal gastric resection can be followed by reconstruction according to the Billroth I (BI) or Billroth II (BII) techniques. The aim of this study was to compare the early postoperative results and complications of patients undergoing BI and those undergoing BII resection. Eighty-eight patients operated during the years 1991 to 1994 underwent distal gastric resection (41 had BI, and 43 had BII resections). The indications for BI resections were gastric tumors in 39 patients (95%) and duodenal ulcer in 2 (5%). The indications for BII resection were malignancy in 28 patients (65%) and duodenal ulcer disease in 15 (35%). The average duration of the procedure was 147 +/- 28 minutes for the BI resection and 175 +/- 38 minutes for the BII resection (p < 0.05). No patient in the BI group developed anastomic leakage. Two patients who underwent BII resection developed duodenal stump leakage (4.7%). Relaparotomy was indicated in five patients, two from the BI group (malignant cells in the resection margins) and three from the BII group (one due to duodenal stump leakage and two for bleeding). There was no postoperative mortality in the BI group. The postoperative mortality in the BII group was 7.1% (p < 0.05). The average proximal gastric resection margins were significantly smaller in the BI group than in the BII group (3.65 +/- 2.83 cm and 5.18 +/- 2.57 cm, respectively; p < 0. 05). The number of lymph nodes found in the resected specimen did not differ significantly between the two groups. Recurrent tumor at the gastric remnant developed in two patients in the BI group but not in the BII group. The results of our study revealed that the BI procedure is accompanied by significantly lower postoperative complication and mortality rates than the BII procedure in cases of gastric malignancy. BI resection performed for malignancy seems to achieve smaller proximal gastric resection margins, which may influence the recurrence rate. PMID:9276708

    Background Video-assisted thoracic surgery (VATS) has been shown to effectively reduce postoperative pain, enhance mobilization of the patients, shorten in-hospital length of stay, and minimize postoperative morbidity rates. The aim of this prospective study is to evaluate neuroendocrine and respiratory parameters as stress markers in cancer patients who underwent lung wedge resections, using both mini muscle-sparing thoracotomy and VATS approach. Methods The patients were randomly allocated into two groups: Group A (n=30) involved patients who were operated on using the VATS approach, while in group B (n=30), the mini muscle-sparing thoracotomy approach was used. Neuroendocrine and biological variables assessed included blood glucose levels, C-reactive protein (CRP) levels, cortisol, epinephrine, and adrenocorticotropic hormone (ACTH) levels. Arterial oxygen (PaO2) and carbon dioxide (PaCO2) partial pressure were also evaluated. All parameters were measured at the following time points: 24 hours preoperatively (T1), 4 hours (T2), 24 hours (T3), 48 hours (T4), and 72 hours (T5), after the procedure. Results PaO2 levels were significantly higher 4 and 24 hours postoperatively in group A vs group B, respectively (T2: 94.3 vs 77.9 mmHg, P=0.015, T3: 96.4 vs 88.7 mmHg, P=0.034). Blood glucose (T2: 148 vs 163 mg/dL, P=0.045, T3: 133 vs 159 mg/dL, P=0.009) and CRP values (T2: 1.6 vs 2.5 mg/dL, P=0.024, T3: 1.5 vs 2.1 mg/dL, P=0.044) were found increased in both groups 4 and 24 hours after the procedure. However, their levels were significantly lower in the VATS group of patients. ACTH and cortisol values were elevated immediately after the operation and became normal after 48 hours in both groups, without significant difference. Postoperative epinephrine levels measured in group A vs group B, respectively, (T2: 78.9 vs 115.6 ng/L, P=0.007, T3: 83.4 vs 122.5 ng/L, P=0.012, T4: 67.4 vs 102.6 ng/L, P=0.021).

    Background/Objectives: Effects of vitamin D deficiency in pregnancy have been associated with some adverse pregnancy outcomes. The objective of this study was to analyze the relationship between vitamin D deficiency in childbearing aged women and pregnancy loss (PL) in the first trimester. Subjects/Methods: This is a cross-sectional study. Plasma was collected from 60 nulliparous women with singleton at 7–9 weeks of gestation (30 with viable gestation and 30 with PL) and 60 non-gravid childbearing aged women (30 with a successful pregnancy history, and 30 with one or more spontaneous first-trimester PL history). Quantitation of serum 25-hydroxyvitamin D (25(OH)D) and 25-hydroxyvitamin D-1 alpha hydroxylase (CYP27B1) was assayed. Results: By pregnancy/non-gravid, normal pregnant women had higher 25(OH)D (49.32 μg/l) and CYP27B1 (82.00 pg/ml) than PL women (34.49 μg/l and 37.87 pg/ml, both P<0.01); the non-gravid women with a successful pregnancy history also had higher 25(OH)D (39.56 μg/l) and CYP27B1 (39.04 pg/ml) than women with PL history (12.30 μg/l and 12.35 pg/ml, both P<0.01). The 96.7% of non-gravid women with PL history and 43.3% of PL women had serum 25(OH)D concentrations below 30 μg/l. There was a strong association between low vitamin D levels and PL (odds ratio 1.71; 95% confidence interval: 1.2–2.4, P<0.001). The regression analyses showed that PL was significantly inversely correlated with 25(OH)D (P<0.01) and CYP27B1 levels (P<0.01). Conclusions: Vitamin D deficiency associated with PL in the first trimester of pregnancy. Decreased serum vitamin D levels among childbearing aged women with the failed clinical pregnancies history may predispose to increased risk for PL. PMID:27222154

    PN is a secreted cell adhesion protein critical for carcinogenesis. Elevated serum levels of PN have been implicated as playing an important role in different types of cancer, and a few reports suggest a potential role as a prognostic marker. We evaluated the prognostic significance of preoperative serum PN concentration in patients with BCa receiving curative surgery. Enzyme-Linked Immunosorbent Assay (ELISA) was performed to determine the preoperative serum PN level in 182 patients. The correlations between serum PN concentration with clinical pathological features and PN expression in primary tumor samples were analyzed. The prognostic impact of serum PN levels with all-cause and BCa-specific mortality was also investigated. Appropriate statistics were used. Elevated serum PN levels were significantly associated with patient age (p = 0.005), adjuvant systemic therapy (p = 0.04) and progesterone receptor (PgR) status (p = 0.02). No correlation between PN preoperative serum levels and other clinical-pathological parameters, including either the epithelial or the stromal PN expression of primary tumor or the combination of the two, was found. Similarly, no association between serum PN levels and either all-cause or BCa-specific mortality was found. However, subgroup analysis revealed a correlation between higher PN serum levels and all-cause mortality in patients with node-negative disease (p = 0.05) and in those with a low PgR expression (p = 0.03). Higher levels of serum PN were also found to correlate with BCa-specific mortality in the subgroup of patients who did not receive any adjuvant systemic therapy (p = 0.04). Our findings suggest that PN was detectable in the serum of early BCa patients before surgery and increased base-line serum levels predicted worse long-term survival outcomes in specific subgroups of patients.

    The use of intravenous dexmedetomidine during surgery has been shown to suppress inflammatory cytokines peri-operatively. It has also been demonstrated that dexmedetomidine may benefit cognitive function in elderly patients following surgery; however, it is not clear whether dexmedetomidine reduces postoperative cognitive dysfunction (POCD) via the suppression of inflammatory cytokines. The aim of the present study was to investigate the effects of dexmedetomidine on early POCD and inflammatory cytokines in elderly patients undergoing laparoscopic cholecystectomy (LC). The study comprised 120 elderly patients undergoing selective LC, who were randomly allocated to receive either dexmedetomidine intravenously (DEX group, n=60) or the same volume of normal saline (control group, n=60). Cognitive function was assessed by Mini-Mental State Examination (MMSE) scores 1 day prior to surgery, 6 h following surgery and postoperatively on days 1 and 2. Interleukin (IL)-1β, IL-6 and C-reactive protein (CRP) levels were also measured at these time-points. On the basis of whether the patients had POCD on the first day after surgery, patients were divided into a POCD group and a non-POCD group. Blood cytokine levels were compared between the patients with and without POCD. A total of 100 patients completed both pre- and postoperative MMSE tests. At 1 day following surgery, POCD occurred in 10/50 (20%) patients in the DEX group and in 21/50 (42%) patients in the control group (P=0.017). At 6 h following surgery, IL-1β, IL-6 and CRP levels showed significant increases (P<0.01) compared with the baseline levels in the two groups. Furthermore, in the control group, CRP levels showed a significant increase on day 1 (P<0.001) and day 2 (P=0.017) postoperatively. In the DEX group compared with the control group, IL-1β, IL-6 and CRP levels were markedly decreased at 6 h and 1 day after surgery (P<0.01). Concentrations of IL-1β, IL-6 and CRP were significantly higher in patients who

    Preclinical studies indicate that brain-derived neurotrophic factor (BDNF) is involved in neuroplastic changes underlying enduring cocaine-seeking following withdrawal. However, little is known about temporal changes in serum BDNF levels or the involvement of BDNF in craving and abstinence in early-abstinent cocaine-dependent patients. Twenty-three cocaine-dependent individuals (aged 33.65 ± 6.85 years) completed a two-week detoxification program at an inpatient facility. Two serum samples were collected for each patient at baseline and at the end of the protocol. Serum samples were also collected for 46 healthy controls (aged 35.52 ± 9.37 years). Demographic, consumption and clinical data were recorded for all patients. Significantly lower serum BDNF levels (p<.0001) were observed for cocaine-dependent patients at baseline compared to healthy controls. Serum BDNF levels increased significantly across 12 days of early abstinence (p=.030). Baseline BDNF levels correlated with craving (p=.034). Post-detoxification BDNF levels correlated with craving (p=.018), loss of control (p<.000), abstinence measures (p=0.031), depression (p=0.036), and anxiety (p=0.036). Post-detoxification BDNF levels also had predictive value for the loss of control measure of craving. Chronic cocaine use is associated with decreased serum BDNF. A progressive increase in serum BDNF levels during early abstinence correlates with cocaine craving and abstinence symptoms and may reflect increasing BDNF levels in different brain regions. These findings suggest that serum BDNF may be a biomarker for cocaine addiction. PMID:23021567

    Plantar fasciotomy is offered to patients with recalcitrant plantar fasciitis. Few studies have characterized the functional outcomes over time for the endoscopic approach compared with the open approach. We hypothesized that patients undergoing endoscopic surgery will have better postoperative functional outcomes early in the postoperative period but equivalent long-term outcomes compared with patients undergoing open surgery. We analyzed the prospectively collected data of all patients undergoing plantar fasciotomy at our institution from December 2007 to August 2014. A total of 42 feet of 38 patients were included in the analysis. The clinical data were collected preoperatively and at 3 and 6 months and 1 year. The functional outcomes analyzed included the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, the Medical Outcomes Study, Short-Form, 36-item Health Survey, and patient satisfaction and expectations. Patients undergoing endoscopic surgery had significantly greater American Orthopaedic Foot and Ankle Society Ankle-Hindfoot and SF-36 Health Survey scores and lower pain scores at the 3-month period. They were also significantly more likely to be satisfied with and have had their expectations met by surgery. Compared with the open approach, the patients who had undergone endoscopic plantar fasciotomy experienced significantly greater improvements in the subjective and objective functional outcomes, with less pain and greater satisfaction, and had had their expectations met earlier in the recovery period, with equivalent long-term outcomes, compared with the patients who had undergone open plantar fasciotomy.

    Introduction: Prompt and accurate diagnosis of sepsis is of high importance for clinicians. Procalcitonine (PCT) and C-reactive protein (CRP) have been proposed as markers for this purpose. Our aim was to evaluate the levels of PCT and CRP in early sepsis and its correlation with severity of sepsis. Methods: Levels of PCT and CRP were taken from 60 patients with sepsis criteria and 39 patients with SIRS symptoms from the University Hospital Center “Mother Teresa” in Tirana, Albania during 2010-2012. Sensitivity, specificity and predictive values for PCT and CRP were calculated. Results: PCT and CRP levels increased in parallel with the severity of the clinical conditions of the patients. The mean PCT level in patients with sepsis was 11.28 ng/ml versus 0.272 ng/ml in patients with SIRS symptoms, with a sensitivity of 97.4% and a specificity of 96.6% for PCT >0.5ng/ml. The mean CRP level in septic patients was 146.58 mg/l vs. 34.4 mg/l in patients with SIRS, with a sensitivity of 98.6% for sepsis and a specificity of 75 % for CRP >11mg/l. Conclusion: PCT and CRP values are useful markers to determine early diagnosis and severity of an infection. In the present study, PCT was found to be a more accurate diagnostic parameter for differentiating SIRS from sepsis and may be helpful in the follow-up of critically ill patients. PMID:23687457

    Peritoneal spread of tumors is a major problem in cancer management. Patients develop a marked deterioration in quality of life and shortened survival. This is in part due to bowel obstructions, marked ascites, and overall increase debilitation. Standard medical management has shown to be inadequate for the treatment of these problems. Surgery can palliate symptoms, however, it is unable to be complete at the microscopic level by a significant spillage of tumor cells throughout the abdomen. Chemotherapy can have some improvement in symptoms however it is short lived due to poor penetration into the peritoneal cavity. The role of intraperitoneal chemotherapy is to maximize tumor penetration and optimize cell death while minimizing systemic toxicity. Hyperthermic intraperitoneal chemotherapy (HIPEC) and early post-operative intraperitoneal chemotherapy (EPIC) are two treatment methods that serve this role and have been shown to improve survival. This review will discuss different chemotherapies used for both of these treatment options. PMID:26941983

    2014-01-01

    Background: Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory disease with autoimmune etiology, characterized by synovial inflammation and destruction of joint cartilage and bone. There are controversial data about the profile of interleukin-17 (IL-17A), interleukin-4 (IL-4), and interferon-gamma (INFγ), indicating in some studies the key role of IL-17, while in others the Th1 cytokines. Materials and Methods: Serum samples of 31 early RA patients were evaluated for erythrocytes sedimentation rate (ESR), rheumatoid factor (RF), C-reactive protein (CRP), anti-cyclic citrullinated peptide antibodies (anti-CCP), and for the tested cytokines (IL-17A, IL-4, and INFγ). Disease activity score (DAS28) calculation was done for all patients. Control serum samples were obtained from 29 healthy volunteers. Results: The levels of tested cytokines were significantly higher (IL-17A, p < 0.001; INFγ, p < 0.001; IL-4, p < 0.01) in patients with early RA, compared to the healthy controls. In early RA patients, a strong correlation of serum IL-17A was found with DAS28, ESR, and CRP. Also, significant negative correlation was found between serum INFγ levels and the DAS28 score, indicating that INFγ may play a key role in maintaining immune homeostasis in patients with RA. Conclusion: The mean serum IL-17A levels in patients with early RA, corresponded with the disease activity and severity. This might highlight the usefulness of the serum IL-17A level in defining the activity and predictive patterns, for aggressive disease therapy, and it might express specific therapeutically targets.

Maternal serum was collected at 19 to 24 and 28 to 32 weeks gestation, and analyzed by liquid chromatography-multiple-reaction monitoring-mass spectrometry. Targeted and shotgun proteomics identified 31 candidate proteins that were differentially expressed in pooled serum samples from spontaneous preterm (<34 weeks - cases) and term deliveries (controls). Candidate protein expression was compared in individual serum samples between cases and controls matched by age and race groups, and clinical site. Protein expression was verified by Western blot in the placenta and fetal membranes from cases and controls. Results Serum samples were available for 35 cases and 35 controls at 19 to 24 weeks, and 16 cases and 16 controls at 28 to 32 weeks. One protein, serpin B7, yielded serum concentrations that differed between cases and controls. The mean concentration of serpin B7 at 28 to 32 weeks was 1.5-fold higher in women with subsequent preterm deliveries compared to controls; there was no difference at 19 to 24 weeks. Higher levels of serpin B7 at both gestational age windows were associated with a shorter interval to delivery, and higher levels of serpin B7 in samples from 28 to 32 weeks were associated with a lower gestational age at delivery. Western blotting identified serpin B7 protein in placenta, amnion, and chorion from cases and controls. Conclusion Targeted and shotgun serum proteomics analyses associated one protein, serpin B7, with early SPTB. Our results require validation in other cohorts and analysis of the possible mechanistic role of serpin B7 in parturition. PMID:24954659

    Purpose This study aimed to investigate whether the prevalence of postoperative pulmonary complications (PPCs) in patients with non-small-cell lung cancer (NSCLC) is even higher in the early stages of COPD than in such patients with normal lung function and to verify the usefulness of symptom- or quality of life (QoL)-based scores in predicting risk for PPCs. Patients and methods Patients undergoing pulmonary resection for NSCLC between July 2012 and October 2014 were prospectively enrolled. Preoperative measurements of lung function, dyspnea, and QoL, operative characteristics, PPCs, duration of postoperative hospitalization, and in-hospital mortality were assessed. Results Among 351 consecutive patients with NSCLC, 343 patients with forced expiratory volume in 1 second (FEV1) ≥70% of predicted value were enrolled. At least one PPC occurred in 57 (16.6%) patients. Prevalence of PPC was higher in patients with COPD (30.1%) than in those with normal spirometry (10.0%; P<0.001). However, in patients with COPD, the prevalence of PPC was not different in patients with FEV1 ≥70% compared to those with FEV1 <70% and between group A (low risk and less symptoms) and group B (low risk and more symptoms) patients with COPD, based on the new Global initiative for chronic Obstructive Lung Disease 2011 guidelines. In patients with COPD, body mass index (odds ratio [OR]: 0.80, P=0.007), carbon monoxide diffusing capacity of the lung (DLCO), % predicted value (OR: 0.97, P=0.024), and operation time (OR: 1.01, P=0.003), but not COPD assessment test or St George Respiratory Questionnaire scores, were significantly associated with PPCs. Conclusion Even in patients with early-stage COPD, the prevalence of PPCs is higher than in patients with NSCLC with normal spirometry. However, this rate is not different between group A and group B patients with COPD. In accordance with this, scores based on symptoms or QoL are not predictors of risk of PPCs in patients with early-stage COPD

    BACKGROUND Because of the restricted data available on patients with postoperative cognitive dysfunction (POCD) in orthotopic liver transplantation (OLT), the goal of our study was to determine the outcome of dexmedetomidine (DEX) on POCD and the mechanism operating in OLT patients. MATERIAL AND METHODS Our study included 80 patients randomly divided into 2 equal groups: the DEX group and the control group. In the DEX group, our patients received an initial dose of DEX at 1 µg/kg for 10 min followed by a continuous infusion at 0.3 µg/kg/h until the end of surgery. The control group received a saline treatment, and neurological tests were performed to assess the status of POCD. Serum level of b-amyloid protein (Aβ) and neuronal microtubule-associated protein (Tau) were measured at designated time points: at pre-operation (T1), 0.5 h after the anhepatic phase (T2), 2 h after the reperfusion of the new liver (T3), at the completion of operation (T4), at day 1 (T5), and at day 7 (T6) after the operation. RESULTS The incidence of POCD was significantly reduced in the DEX group (P=0.017). The score from the neurological tests was significantly decreased in the control group after the operation, but no statistical difference was observed in the DEX group. The DEX groups demonstrated a lower level of β-amyloid and Tau protein than those at the corresponding time points (T4~T6) in the control group (P<0.01). CONCLUSIONS Dexmedetomidine reduced the incidence of postoperative cognitive dysfunction in orthotopic liver transplantation patients. The decreased levels of b-amyloid and Tau protein may have contributed to this favorable outcome. PMID:27527391

    Background: Pain and shivering are two challenging components in the post operative period. Many drugs were used for prevention and treatment of them. The aim of this study was to compare the effects of prophylactic prescription of diclofenac suppository versus intravenous (IV) pethidine in spinal anesthesia. Materials and Methods: We conducted a multi central, prospective, double-blind, randomized clinical trial on a total of 180 patients who were scheduled for surgery under spinal anesthesia including 60 patients in three groups. Patients were randomly allocated to receive 100 mg sodium diclofenac suppository or 30 mg IV pethidine or placebo. Categorical and continuous variables were analyzed by Chi-square test, t-test, Mann-Whitney and ANOVA or Kruskal-Wallis tests. Results: There was no statistical difference with regard to patient characteristics and hemodynamic indices among the three groups. Nine (15%), 10 (16.65%) and 24 (40%) of patients in diclofenac, pethidine and control groups reported pain and 2, 2, 7 patients received treatment due to it, respectively (P = 0.01). Prevalence of shivering in pethidine group and diclofenac group was the same and both of them were different from the control group (P < 0.001). Pruritus was repetitive in the pethidine group and was statistically significant (P = 0.036) but, post-operative nausea and vomiting was not significantly different among groups. Conclusion: A single dose of sodium diclofenac suppository can provide satisfactory analgesia immediately after surgery and decrease shivering without remarkable complications. This investigation highlights the role of pre-operative administration of a single dose of rectal diclofenac as a sole analgesic for early post-operative period. PMID:24803766

    Study Design Case-control study. Purpose To identify the characteristics of candidate indexes for early detection of surgical site infection (SSI). Overview of Literature SSI is a serious complication of spinal instrumentation surgery. Early diagnosis and treatment are crucial for the welfare of the patient postoperation. Methods We retrospectively reviewed laboratory data of patients who underwent posterior lumbar instrumentation surgery for degenerative spine disease. The sensitivity and specificity of six laboratory markers for early detection of SSI were calculated: greater elevation of the white blood cell count at day 7 than at day 4 postoperatively, greater elevation of the C-reactive protein (CRP) level at day 7 than at day 4 postoperatively, a CRP level of >10 mg/dL at 4 days postoperatively, neutrophil percentage of >75% at 4 days postoperatively, a lymphocyte percentage of <10% at 4 days postoperatively, and a lymphocyte count of <1,000/µL at 4 days postoperatively. Statistical analysis was via Fisher's exact test and a p-value of <0.05 was considered significant. Results In total, 85 patients were enrolled. Of these, five patients developed deep SSI. The sensitivity and specificity of each index were as follows: index 1, 20.0% and 77.5%; index 2, 20.0% and 83.8%; index 3, 40.0% and 97.5%; index 4, 40.0% and 86.3%; index 5, 0% and 96.3%; and index 6, 80.0% and 80.0%. A significant difference was noted for indexes 3 and 6. Conclusions A CRP level of >10 mg/dL at 4 days postoperatively would be useful for definitive diagnosis of SSI, and a lymphocyte count of <1,000/µL at 4 days postoperatively would be a useful screening test for SSI. Although laboratory markers for early detection of SSI have been frequently reported, we believe that it is important to understand the characteristics of each index for a precise diagnosis.

    Objectives: Although good clinical outcomes of autologous osteochondral plug grafts for capitellar osteochondritis dissecans (OCD) have been reported, the timing of return to sports was various and still controversial. The period of graft incorporation and the lesion healing at repair site is important to establish the rehabilitation protocol, however there is little information. The aim of this study was to investigate early postoperative magnetic resonance imaging (MRI) findings and clinical outcomes after autologous osteochondral plug grafts for capitellar OCD. Methods: Fifteen young baseball players with advanced lesions of capitellar OCD underwent a procedure using autologous osteochondral plug grafts and underwent MRI (1.5 T) scan at 3 and 6 months, postoperatively. Their mean age at the time of surgery was 13.5 years (range, 13-15 years). Four lesions were classified as International Cartilage Repair Society (ICRS) OCD III and 11 lesions as OCD IV. The mean size of the lesions (sagittal × coronal) was 16 × 14 mm and the mean surface area was 181 mm2. One to two osteochondral plug grafts, with a mean diameter of 7 mm (range, 6-8 mm), were harvested from the lateral femoral condyle and transplanted to the defects. The mean reconstruction rate was 41% (range, 12%-65%), which was calculated as (total surface area of the grafts × 100%)/ (surface area of the lesion). Patients were allowed to begin throwing after 3 months and to return to sports after 6 months. The mean follow-up was 21 months (range, 12-36 months). The MRI findings were assessed graft incorporation, which was indicated by no T1-low-signal-intensity at the graft and no fluid surrounding the graft on T2-weighted fat-suppression (Figure 1), and the lesion healing according to the scoring system of Henderson (4, complete healing; 16, no healing). MRI were blinded and randomized, and two observers reviewed independently and conferred when they differed. Clinical outcomes were evaluated as elbow pain

    Accidental radiation exposure is a threat to human health that necessitates effective clinical planning and diagnosis. Minimally invasive biomarkers that can predict long-term radiation injury are urgently needed for optimal management after a radiation accident. We have identified serum microRNA (miRNA) signatures that indicate long-term impact of total body irradiation (TBI) in mice when measured within 24 hours of exposure. Impact of TBI on the hematopoietic system was systematically assessed to determine a correlation of residual hematopoietic stem cells (HSCs) with increasing doses of radiation. Serum miRNA signatures distinguished untreated mice from animals exposed to radiation and correlated with the impact of radiation on HSCs. Mice exposed to sublethal (6.5 Gy) and lethal (8 Gy) doses of radiation were indistinguishable for 3 to 4 weeks after exposure. A serum miRNA signature detectable 24 hours after radiation exposure consistently segregated these two cohorts. Furthermore, using either a radioprotective agent before, or radiation mitigation after, lethal radiation, we determined that the serum miRNA signature correlated with the impact of radiation on animal health rather than the radiation dose. Last, using humanized mice that had been engrafted with human CD34+ HSCs, we determined that the serum miRNA signature indicated radiation-induced injury to the human bone marrow cells. Our data suggest that serum miRNAs can serve as functional dosimeters of radiation, representing a potential breakthrough in early assessment of radiation-induced hematopoietic damage and timely use of medical countermeasures to mitigate the long-term impact of radiation.

    Serum concentrations of copper (Cu), zinc (Zn), manganese (Mn), calcium (Ca) and inorganic phosphorus (P), as well as antigenic ceruloplasmin (Cp) and oxidase activity as a functional index for copper metabolism, were measured in 10 foals (5 males and 5 females) and their dams. Samples were harvested from the foals within 1 wk after birth and monthly from 1 to 17 mo of age. Samples were collected from their dams in the perinatal period (monthly from 2 mo before delivery to 5 mo postpartum). Serum oxidase activity, antigenic Cp and Cu in foals were extremely low at 1 wk. Serum Cp had the lowest value of 17.0 +/- 8.0 (mean +/- SD) mg/dL within the 1st wk, then increased rapidly up to 43.7 +/- 5.8 mg/dL at 1 mo, and maintained this level until the 17th mo. Serum Zn in foals had the highest value of 73.2 +/- 13.1 micrograms/dL within 1 wk, then decreased to 38.3 +/- 5.9 micrograms/dL by 17 mo. Serum Mn, Ca and P in mares were almost stable and within established reference ranges for our laboratory in the perinatal period, and these values in foals were also in the normal range. Even on appropriate feeding, serum Cu, Cp and oxidase activity were quite low a few weeks after birth, while a higher proportion of Cp-binding copper was found in the foals. This might be caused by the limited synthesis of ceruloplasmin in this period. These data suggest that newborn foals are in a critical situation of marginal copper status in the early stage of growth. PMID:9553711

    Liver transplantation with the use of donation after circulatory death (DCD) is associated with ischemic cholangiopathy (IC) often leading to graft loss. We hypothesized that serial postoperative analysis of alkaline phosphatase and bilirubin might identify patients who would later on develop ischemic cholangiopathy and/or graft loss, allowing early recognition and potentially retransplantation. The University of Washington DCD experience totals 89 DCD liver transplantations performed from 2003 to 2011 with Kaplan-Meier estimated 5-year patient and graft survival rates of 81.6% and 75.6%, respectively; 84/89 patients transplanted with DCD livers lived ≥ 60 days after transplantation and were analyzed. Serum bilirubin and alkaline phosphatase levels at 1 week, 2 week, 1 month, and 2 months after transplantation were analyzed. Two-month serum bilirubin and alkaline phosphatase proved to have the strongest associations with development of IC and graft failure. Two-month alkaline phosphatase of <100 U/L had a negative predictive value of 97% for development of IC. Two-month alkaline phosphatase demonstrated an inflection starting at >300 U/L strongly associated with development of IC (P < .0001). Serum bilirubin at 2 months was most strongly associated with graft failure within the 1st year with a strong inflection point at 2.5 mg/dL (P = .0001). All jaundiced recipients at 60 days after transplantation (bilirubin >2.5 mg/dL) developed graft failure within the 1st year (P < .0001). Use of these early surrogate markers could facilitate prioritization and early retransplantation for DCD liver recipients with allografts destined for failure.

    We aimed to identify microRNA (miRNA) expression patterns in the serum of prostate cancer (CaP) patients that predict the risk of early treatment failure following radical prostatectomy (RP). Microarray and Q-RT-PCR analyses identified 43 miRNAs as differentiating disease stages within 14 prostate cell lines and reflectedpublically available patient data. 34 of these miRNA were detectable in the serum of CaP patients. Association with time to biochemical progression was examined in a cohort of CaP patients following RP. A greater than two-fold increase in hazard of biochemical progression associated with altered expression of miR-103, miR-125b and miR-222 (p <.0008) in the serum of CaP patients. Prediction models based on penalized regression analyses showed that the levels of the miRNAs and PSA together were better at detecting false positives than models without miRNAs, for similar level of sensitivity. Analyses of publically available data revealed significant and reciprocal relationships between changes in CpG methylation and miRNA expression patterns suggesting a role for CpG methylation to regulate miRNA. Exploratory validation supported roles for miR-222 and miR-125b to predict progression risk in CaP. The current study established that expression patterns of serum-detectable miRNAs taken at the time of RP are prognostic for men who are at risk of experiencing subsequent early biochemical progression. These non-invasive approaches could be used to augment treatment decisions. PMID:24583788

    With the recent development of novel technologies capable of comprehensively detecting and accurately identifying small molecules within biological samples--the field of metabolomics--new information about disease biology is emerging. A comprehensive metabolomics strategy was used to discover novel small molecules which were significantly decreased in the serum of colorectal cancer (CRC) patients relative to normal individuals. The metabolite markers, hydroxylated polyunsaturated ultra long-chain fatty acids (hPULCFAs), were characterized using HPLC-coupled tandem mass spectrometry, and a high-throughput screening (HTS) method compatible with conventional triple-quadrupole mass spectrometers in clinical labs. around the world was developed. The HTS method was used to determine serum levels of the 28 carbon-containing hPULCFA C28H46O4 (named GTA-446) in independent clinical validation studies to investigate the effect of tumor removal after surgery, chemo- or radiation therapy and the correlation with age. We have also obtained results from a two-year prospective trial. Serum samples from a representative cohort of physician-referred colonoscopy subjects (n = 4,923) were collected between July 2008 and August 2010. Ninety-eight new CRC cases were detected in the colonoscopy cohort. Overall sensitivity in this cohort was 85.7%, with 86.5% in the early stage (0-II) and 84.8% in the late-stage (III-IV). This trial represents the first prospective study of this magnitude investigating a metabolic biomarker for CRC. The results indicate that pre-colonoscopy screening using serum GTA-446 levels is a viable approach to detecting early-stage CRC. PMID:26524856

    Purpose A simple needling procedure is the standard method for restoring the function of an encapsulated bleb after trabeculectomy. However, postoperative hypotony represents a possible hazard. This study describes a new surgical approach for treating encapsulated blebs with reduced risk of early postoperative hypotony: bleb needling combined with transconjunctival sutures tightening the scleral flap directly. Methods The study included two groups of 23 patients with failing bleb following trabeculectomy: “Group 1” underwent simple needling revision of the filtering bleb and served as a control group, while “Group 2” received needling revision with additional transconjunctival scleral flap sutures, if intraoperatively the intraocular pressure was estimated to be very low. Intraocular pressure (IOP), postoperative management and complications were analyzed over a follow-up period of 4 weeks postoperatively. Results were compared using t-test or Mann-Whitney U-tests. Results Adverse effects occurred with a higher frequency after sole needling of the bleb (5 cases of choroidal effusion and 1 case of choroidal hemorrhage) than after the combined method with additional scleral sutures (1 case of choroidal effusion). The IOP on the first postoperative day was significantly lower in group 1, with 9.43 ± 9.01 mm Hg vs. 16.43 ± 8.35 mm Hg in group 2 (P = 0.01). Ten patients with ocular hypotony (IOD of 5 mmHg or lower) were found in group 1 and only two in group 2. One week and one month after surgery the intraocular pressure was similar in both groups (P>0.05). Conclusions This new needling technique with additional transconjunctival scleral flap sutures appears to reduce postoperative hypotony, and may thus protect from further complications, such as subchoroidal hemorrhage.

    Sera from rabbits with early experimental syphilis were tested for their effect on in vitro lymphocyte transformation responses to related specific antigens (sonicated T. pallidum), unrelated specific antigens (sheep erythrocytes), and the T cell mitogen, concanavalin A. Results were compared with responses in preinfection sera and in sera from sham-infected rabbits. Titration experiments in which normal serum was used indicated that optimal lymphocyte responsiveness is obtained with a final serum concentration of 1%. Under these conditions, no differences in concanavalin A stimulation were observed in cultures with syphilitic sera. Responses to sonicated T. pallidum were inhibited, but only by 17 to 25% when compared with the response in preinfection sera. In cultures containing 10% serum, inhibition of lymphocyte proliferation to sonicated T. pallidum antigens was evident with sera from all syphilitic animals from day 10 (55% inhibition) through day 31 (80% inhibition) of infection. Responses to concanavalin A and sheep erythrocytes were significantly inhibited by day 10 sera; only 20% of the sera tested demonstrated substantial nonspecific inhibitory capacity. No differences were evident among sera from any of the sham-infected animals or among the preinfection sera from either group. Pooled serum with high inhibitory activity was fractionated by ammonium sulfate precipitation, DEAE ion exchange chromatography, and Sephadex G-200 gel filtration. Two separate inhibitors were identified: (i) a low-molecular-weight, ammonium sulfate-soluble, nonspecific inhibitory fraction containing albumin and alpha-globulins with the capacity to inhibit both antigen and mitogen responses and (ii) a high-molecular-weight, ammonium sulfate-precipitable, inhibitory fraction containing alpha-globulin and FTA-ABS-reactive immunoglobulin M which affected only the antigen-specific response to sonicated T. pallidum. Immunodiffusion failed to detect immunoglobulin or T. pallidum antigens

    Metabolic bone disease of prematurity is a condition characterized by reduction in bone mineral content (osteopenia). It is a problem faced by very low birth weight (VLBW) infants because of lack of fetal mineralization during the last trimester. Our aim was to assess serum alkaline phosphatase (ALP) level as an early biomarker for osteopenia in premature infants and to estimate an optimal cutoff value of serum ALP at which osteopenia is detected radiologically in premature newborns.This prospective study was conducted on a cohort of 120 newborn infants of both sex of ≤34 weeks' gestational age and <1500 g birth weight. Two blood samples, from each infant on at least 2 consecutive weeks, were reported for calcium, phosphorus, and ALP. Evidence of osteopenia was evaluated radiologically by performing wrist/knee x-ray.Sixteen infants (13.3%) had evidence of osteopenia in x-ray, whereas 104 infants (86.7%) were nonosteopenic and all the osteopenic infants were <1000-g birth weight. Birth weight and gestational age were significantly inversely related to serum ALP levels. Both samples showed statistically significantly higher mean ALP level in osteopenic than nonosteopenics (P < 0.001, and P < 0.001 respectively). There was no constant value of serum ALP related to radiologic evidence of osteopenia. However, the optimal cutoff value of serum ALP at which osteopenia is detected is 500 IU/L with 100% sensitivity and 80.77% specificity.High levels of ALP can be considered a reliable biomarker to predict the status of bone mineralization and the need for radiological evaluation in premature infants particularly those <1000-g birth weight and <32 weeks' gestation.

    Overweight and obese patients are at especially high risk for delayed awakening after general surgery. Whether this risk also applies to cerebral neurosurgical procedures remains unclear. This study evaluated early postoperative cognitive recovery and gas exchange patterns, after balanced anesthesia with sevoflurane or desflurane, in overweight and obese patients undergoing craniotomy for supratentorial expanding lesions. Fifty-six patients were consecutively enrolled, and randomly assigned to 1 of 2 study groups to receive balanced anesthesia with sevoflurane or desflurane. Cognitive function was evaluated with the Short Orientation Memory Concentration Test and the Rancho Los Amigos Scale and gas exchange patterns (pH, PaO2, and PaCO2) were recorded in all patients at 5 time-points: preoperatively and postoperatively, after patients reached an Aldrete score >or=9, at 15, 30, 45, and 60 minutes. Preoperative cognitive status was similar in the 2 treatment groups. Early postoperative cognitive recovery was more delayed and Short Orientation Memory Concentration Test scores at 15 and 30 minutes postanesthesia were lower in patients receiving sevoflurane-based anesthesia than in those receiving desflurane-based anesthesia (21.5+/-3.5 vs. 14.9+/-3.5) (P<0.005) and (26.9+/-0.7 vs. 21.5+/-1.4) (P<0.005), and the postoperative Rancho Los Amigos Scalegrade 8 showed a similar trend (25/28 patients 89% vs. 8/28 patients 28% (P<0.005) and 28/28 patients (100% vs. 13/28 patients 46%) (P<0.005). Similarly, gas-exchange analysis showed higher PaCO2 at 15 and 30 minutes and lower pH up to 45 minutes postextubation in patients receiving sevoflurane-based anesthesia. In overweight and obese patients undergoing craniotomy desflurane-based anesthesia allows earlier postoperative cognitive recovery and reversal to normocapnia and normal pH. PMID:19542997

Similarly, gas-exchange analysis showed higher PaCO2 at 15 and 30 minutes and lower pH up to 45 minutes postextubation in patients receiving sevoflurane-based anesthesia. In overweight and obese patients undergoing craniotomy desflurane-based anesthesia allows earlier postoperative cognitive recovery and reversal to normocapnia and normal pH.

    Introduction Postoperative delirium is common in older patients. Despite its prognostic significance, the pathophysiology is incompletely understood. Although many risk factors have been identified, no reversible factors, particularly ones potentially modifiable by anaesthetic management, have been identified. The goal of this prospective cohort study was to investigate whether intraoperative hypotension was associated with postoperative delirium in older patients undergoing major non-cardiac surgery. Methods Study subjects were patients >65 years of age, undergoing major non-cardiac surgery, who were enrolled in an ongoing prospective observational study of the pathophysiology of postoperative delirium. Intraoperative blood pressure was measured and predefined criteria were used to define hypotension. Delirium was measured by the Confusion Assessment Method on the first two postoperative days. Data were analysed using t-tests, two-sample proportion tests and ordered logistic regression multivariable models, including correction for multiple comparisons. Results Data from 594 patients with a mean age of 73.6 years (sd 6.2) were studied. Of these 178 (30%) developed delirium on day 1 and 176 (30%) on day 2. Patients developing delirium were older, more often female, had lower preoperative cognitive scores, and underwent longer operations. Relative hypotension (decreases by 20, 30, or 40%) or absolute hypotension [mean arterial pressure (MAP)<50 mm Hg] were not significantly associated with postoperative delirium, nor was the duration of hypotension (MAP<50 mm Hg). Conversely, intraoperative blood pressure variance was significantly associated with postoperative delirium. Discussion These results showed that increased blood pressure fluctuation, not absolute or relative hypotension, was predictive of postoperative delirium. PMID:25616677

    Objectives: To compare the effect of cataract surgery on anterior segment parameters measured by optical biometry in primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PXG). Materials and Methods: Twenty-five eyes of 25 patients with POAG and 29 eyes of 29 patients with PXG who had uncomplicated phacoemulsification and posterior chamber intraocular lens implantation surgery were included to our prospective study. Central corneal thickness (CCT), anterior chamber depth (ACD) and axial length (AL) were measured with an optical biometer preoperatively and at 1 month postoperatively. The pre- and postoperative values of intraocular pressure (IOP) and the anterior segment parameters and the differences between POAG and PXG were compared statistically by paired t, independent t and chi-square tests. Results: The mean values of preoperative CCT (p=0.042) and ACD (p=0.012) were significantly lower in the PXG than in the POAG group. In the PXG group, IOP decreased (p=0.001) but CCT (p=0.03) and ACD (p=0.001) increased significantly postoperatively; AL did not change significantly. In the POAG group, IOP decreased (p=0.01) and ACD (p=0.004) increased significantly postoperatively, while AL and CCT did not change significantly. There were no significant differences in the pre- to postoperative changes in IOP (p=0.76), AL (p=0.44) and CCT (p=0.52) values between the two groups. However, the postoperative increase in ACD was larger in the PXG group (p=0.03). Conclusion: Cataract surgery may cause some changes in IOP and anterior segment parameters like ACD and CCT postoperatively in eyes with POAG and PXG, and these changes may differ between eyes with PXG and POAG.

    Chronic HBV (CHB) infected patients with intermediate necroinflammation and fibrosis are recommended to receive antiviral treatment. However, other than liver biopsy, there is a lack of sensitive and specific objective method to determine the necroinflammation and fibrosis stages in CHB patients. This study aims to identify unique serum metabolomic profile associated with histological progression in CHB patients and to develop novel metabolite biomarker panels for early CHB detection and stratification. A comprehensive metabolomic profiling method was established to compare serum samples collected from health donor (n = 67), patients with mild (G < 2 and S < 2, CHB1, n = 52) or intermediate (G ≥ 2 or S ≥ 2, CHB2, n = 36) necroinflammation and fibrosis. Multivariate models were developed to differentiate CHB1 and CHB2 from controls. A set of CHB-associated biomarkers was identified, including lysophosphatidylcholines, phosphatidylcholines, phosphatidylinositol, phosphatidylserine, and bile acid metabolism products. Stratification of CHB1 and CHB2 patients by a simple logistic index, the PIPSindex, based on phosphatidylinositol (PI) and phosphatidylserine (PS), was achieved with an AUC of 0.961, which outperformed all currently available markers. A panel of serum metabolites that differentiate health control, CHB1 and CHB2 patients has been identified. The proposed metabolomic biosignature has the potential to be used as indicator for antiviral treatment for CHB management. PMID:27498553

    Objective: To evaluate the effects of early enteral micro-feeding on neonatal serum vitamin D levels, and to analyze the application value of glutamine. Methods: One hundred ninty neonates enrolled in intensive care unit were randomly divided into a treatment group and a control group (n=95) that were both given enteral and parenteral nutrition support. Meanwhile, the treatment group was fed formula milk containing 0.3 g/(kg·d) glutamine as enteral nutrition support for 14 days. Results: The weight of the treatment group increased significantly faster than that of the control group did (P<0.05). The treatment group had significantly higher milk amount and calorie intake than those of the control group (P<0.05), and neonates in the treatment group who reached calorie intake of 50/80/100 kcal/kg/d were significantly younger (P<0.05). Meanwhile, the treatment group was significantly less prone to feeding intolerance than the control group (P<0.05). After 14 days of feeding, the serum motilin, gastrin and vitamin D levels of both groups all increased, with significant intra-group and inter-group differences. Such levels of the treatment group significantly exceeded those of the control group (P<0.05). Conclusion: Supplementing early enteral micro-feeding with glutamine promoted the absorption of neonatal routine nutrients and vitamin D, obviously regulated gastrointestinal hormones, and elevated weight as a result.

    Relapse remains the major cause of mortality for patients with Acute Myeloid Leukemia (AML). Improved tracking of minimal residual disease (MRD) holds the promise of timely treatment adjustments to preempt relapse. Current surveillance techniques detect circulating blasts that coincide with advanced disease and poorly reflect MRD during early relapse. Here, we investigate exosomes as a minimally invasive platform for a microRNA (miRNA) biomarker. We identify a set of miRNA enriched in AML exosomes and track levels of circulating exosome miRNA that distinguish leukemic xenografts from both non-engrafted and human CD34+ controls. We develop biostatistical models that reveal circulating exosomal miRNA at low marrow tumor burden and before circulating blasts can be detected. Remarkably, both leukemic blasts and marrow stroma contribute to serum exosome miRNA. We propose development of serum exosome miRNA as a platform for a novel, sensitive compartment biomarker for prospective tracking and early detection of AML recurrence. PMID:26067326

    The aim of this study was to determine whether the increased serum cell-free fetal DNA (cffDNA) level of gravidas developed into early-onset preeclampsia (EOPE) subsequently in the early second trimesters is related to prenatal screening markers. Serum was collected from 1011 gravidas. The level of cffDNA and prenatal screening markers were analyzed in 20 cases with EOPE and 20 controls. All fetuses were male. The maternal serum cffDNA level was assessed by amplification of the Y chromosome specific gene. Correlations between the variables were examined. (Logged) cffDNA in EOPE (median, 3.08; interquartile range, 2.93–3.68) was higher than controls (median, 1.79; interquartile range, 1.46–2.53). The increased level of (logged) cffDNA was correlated significantly with the increased human chorionic gonadotropin (HCG) level (r = 0.628, p < 0.001). Significant reciprocal correlations between cffDNA and babies’ birth weight as well as gestation weeks at delivery were noted (r = −0.516, p = 0.001; r = −0.623, p < 0.001, respectively). The sensitivity and specificity of cffDNA to discriminate between the EOPE cases and the controls were 90% and 85%, respectively. CffDNA is a potential marker for EOPE, which had a significant reciprocal correlation with babies’ birth weight and gestation weeks at delivery. Moreover, it may help in indicating the underlying hypoxic condition in the placenta. PMID:23567271

    Background: Off-pump coronary artery bypass grafting (OPCAB) has evolved into a standard technique in coronary artery bypass grafting. However, a detailed investigation in Japanese population undergoing OPCAB has not yet been fully elucidated. Methods: A total of 1109 consecutive patients undergoing isolated OPCAB between 2006 and 2013 at Juntendo University were reviewed. The data was evaluated in the light of previously published OPCAB-associated reports. Results: There were 904 male (81.5%) and a mean was 67.5 ± 9.8 years. Eight patients (0.5%) died within 30 days postoperatively or before discharge, which was equivalent to or rather better than the previously reported mortality rates, including the European System for Cardiac Operation Risk Evaluation II (2.1 ± 2.1) data. A morbidity analysis revealed that prolonged intubation (>24 h) occurred in 43 patients (3.6%), surgical site infections in 18 (1.9%), neurological complications in 13 (1.3%). A reduced preoperative left ventricular ejection fraction (less than 40%) was found to be a risk factor for early postoperative death (odds ratio 10.58, respectively, p <0.05) in our cohort. Conclusions: Early postoperative mortality and morbidity rates in Japanese population after OPCAB were rather satisfactory and similar to those reported by other countries. PMID:26597169

    Every surgeon should have a thorough knowledge and awareness of the general principles of postoperative infections. The key to postoperative infections is in their prevention. Even with the most prudent and ardent regimens, however, postoperative wound infections will occasionally occur. Thus, the aforementioned knowledge will allow an improved clinical acumen and permit the early diagnosis of postoperative infection. Early and vigorous local wound care combined with systemic antibiotics are necessary to minimize the potentially debilitating sequelae of the postoperative wound infection.

    Early pregnancy failure is a common pregnancy complication. In clinical practice, the time delay to distinguish viable from nonviable pregnancy is often distressing to patients and doctors. A highly sensitive and specific biomarker that accurately discriminates between viable and nonviable pregnancy would be useful for early intervention. Progesterone has been shown as a biomarker of early pregnancy failure. However the usefulness is still questionable due to the different cutoff values used. A study was conducted to determine the role of progesterone as a marker of early pregnancy failure and to establish the cut-off value in discriminating between viable and nonviable pregnancy. The study was carried out in the Obstetric and Gynecology Patient Admission Centre (OBPAC), Universiti Kebangsaan Malaysia Medical Centre (UKMMC) for a period of twelve months. Ninety-five pregnant women of 13 weeks or less period of amenorrhoea (POA) were recruited. Fourteen normal pregnant women were controls. The patients with early pregnancy failure were classified according to types of abortion. Single measurement of serum progesterone was carried out during admission. The outcome of pregnancy was followed up until 22 weeks of POA to ascertain viability of the fetus. Median progesterone levels were significantly lower in women with nonviable pregnancies compared with viable pregnancy [10.7ng/ml (0.60-49.80) vs. 45.9ng/ml (15.40-127.20) respectively, p<0.001]. Progesterone levels were also significantly lower in threatened abortion patients with outcomes of nonviable pregnancy compared with pregnancies that progressed on to the viability period [23.3 +/- 12.0 vs. 89.7 +/- 33.2 respectively, p<0.001]. At cut-off value of 32.7ng/ ml, progesterone had 90% sensitivity with 75% negative predictive value and 92% specificity with 97% positive predictive value. The area under curve for progesterone was 0.95 (95% Confidence Interval, 0.903-0.990). In conclusion, these findings indicate that

    Low cardiac output syndrome (LCOS) and maximum vasoactive inotropic score (VIS) have been used as surrogate markers for early postoperative outcomes in pediatric cardiac surgery. The objective of this study was to determine the associations between LCOS and maximum VIS with clinical outcomes in neonatal cardiac surgery. This was a secondary retrospective analysis of a prospective randomized trial, and the setting was a pediatric cardiac intensive care unit in a tertiary care children's hospital. Neonates (n = 76) undergoing corrective or palliative cardiac operations requiring cardiopulmonary bypass were prospectively enrolled. LCOS was defined by a standardized clinical criteria. VIS values were calculated by a standard formula during the first 36 postoperative hours, and the maximum score was recorded. Postoperative outcomes included hospital mortality, duration of mechanical ventilation, intensive care unit (ICU) and hospital lengths of stay (LOS), as well as total hospital charges. At surgery, the median age was 7 days and weight was 3.2 kg. LCOS occurred in 32 of 76 (42%) subjects. Median maximum VIS was 15 (range 5–33). LCOS was not associated with duration of mechanical ventilation, ICU LOS, hospital LOS, and hospital charges. Greater VIS was moderately associated with a longer duration of mechanical ventilation (p = 0.001, r = 0.36), longer ICU LOS (p = 0.02, r = 0.27), and greater total hospital costs (p = 0.05, r = 0.22) but not hospital LOS (p = 0.52). LCOS was not associated with early postoperative outcomes. Maximum VIS has only modest correlation with duration of mechanical ventilation, ICU LOS, and total hospital charges. PMID:22349666

    Inadequate pain relief after lower limb joint replacement surgery has been a well-recognised limiting factor affecting post-operative mobilisation and length of hospital stay. Multimodal local wound infiltration with local anaesthetics, adrenaline and non-steroidal anti-inflammatory agents can lower the opiate intake, reduce the length of stay and enhance early mobilisation in knee replacement patients. A retrospective review of 64 patients undergoing primary total knee replacement was undertaken. Thirty-two patients (cases) had their wounds infiltrated with ropivacaine, adrenaline and ketorolac by the operating surgeon, intraoperatively. Subsequently, a 19G wound catheter placed into the knee joint. They received two further top-up doses of the same combination at 10 and 20 h post-operatively. This group was compared with a control group of 32 patients who did not receive any local infiltration. Both groups were comparable in terms of BMI and age. Post-operative opiate drug consumption in first 48 h after surgery, length of hospital stays and time taken to mobilise after surgery were recorded. There was significant reduction in opiate consumption in the treatment group with an average consumption of 49.35 mg of morphine compared to 71.48 mg in the control group (p = 0.004). The median length of hospital stay was significantly reduced from 5 days in the control group to 4 days in the treatment group (p = 0.03). The patients in the treatment group mobilised around 19 h earlier (p = 0.001). No major post-operative complications were encountered in either group. Wound infiltration is an effective and safe technique that promotes early rehabilitation and discharge of patients following primary total knee replacement.

    Takotsubo syndrome, also known as broken-heart syndrome, stress-induced cardiomyopathy or transient apical ballooning syndrome, is a transient disorder characterized by segmental left ventricular failure in the absence of obstructive coronary artery disease. Most cases of Takotsubo syndrome are caused by acute stress that leads to a sudden, temporary weakening of the cardiac musculature. This stress triggers a rise in circulating catecholamine levels that results in acute ventricular dysfunction. In this report, we describe two cases of Takotsubo syndrome in the early postoperative period after bariatric surgery.

    Introduction Accumulating evidence suggests that enhanced inflammatory responses contribute to the pathogenesis of postoperative cognitive dysfunction (POCD). Blood transfusion can trigger an enhancement of acute inflammatory responses. Therefore, we hypothesized that perioperative blood transfusion is associated with a higher risk of POCD in aged patients following total hip replacement surgery. Material and methods Patients older than 65 years undergoing elective total hip replacement surgery were enrolled from October 2011 to December 2012. Neurocognitive tests were evaluated at baseline and at 7 d after surgery by a Mini-Mental State Test. Multivariate logistic regression analysis was used to determine risk factors associated with POCD. Results Fifty-six patients (27.3%) developed POCD 7 d postoperatively. Patients who developed POCD were older, had a lower education level and preoperative hemoglobin concentration, had more blood loss, and had a lower body weight (p < 0.05). Patients with POCD were more likely to receive red blood cells (RBCs) transfusion (51.8% versus 31.5%; p < 0.05). A multivariable logistic regression model identified older age, lower education level, and perioperative blood transfusion of more than 3 units as independent risk factors for POCD 7 d postoperatively. Conclusion Our data suggested that perioperative blood transfusion of more than 3 units of RBCs is an independent risk factor for POCD in aged patients following total hip replacement surgery.

    Myeloma kidney is the major cause of severe irreversible renal failure in patients with multiple myeloma. This tubulointerstitial injury is a direct consequence of high concentrations of circulating monoclonal free light chains (FLCs) produced by a clonal expansion of plasma cells. Early reduction of serum FLCs associates with renal recovery, but the target threshold of reduction to facilitate renal recovery is unknown. To determine the relationship between the achieved FLC reduction and renal recovery, we identified 39 patients with biopsy-proven myeloma kidney, the majority of whom had severe renal failure at presentation (median estimated GFR 9 ml/min per 1.73 m2). In a multivariable analysis incorporating demographic, hematologic, and renal variables, only the achieved FLC reduction significantly predicted renal recovery (P = 0.003). The relationship between renal recovery and FLC reduction was linear with no absolute threshold for FLC reduction. A 60% reduction in FLCs by day 21 associated with recovery of renal function for 80% of the population. Patient survival strongly associated with renal recovery: the median survival was 42.7 months (range 0 to 80) among those who recovered function compared with 7.8 months (range 0 to 54) among those who did not (P < 0.02). Cox-regression analysis demonstrated that the first presentation of myeloma, the kappa isotype of FLC, and renal recovery were independent predictors of survival. In conclusion, recovery of renal function in myeloma kidney depends on early reduction of serum FLCs, and this recovery associates with a significant survival advantage. PMID:21511832

    Background Early prostate cancer antigen (EPCA) has been shown a prostate cancer (PCa)-associated nuclear matrix protein, however, its serum status and prognostic power in PCa are unknown. The goals of this study are to measure serum EPCA levels in a cohort of patients with PCa prior to the treatment, and to evaluate the clinical value of serum EPCA. Methods Pretreatment serum EPCA levels were determined with an ELISA in 77 patients with clinically localized PCa who underwent radical prostatectomy and 51 patients with locally advanced or metastatic disease who received primary androgen deprivation therapy, and were correlated with clinicopathological variables and disease progression. Serum EPCA levels were also examined in 40 healthy controls. Results Pretreatment mean serum EPCA levels were significantly higher in PCa patients than in controls (16.84±7.60 ng/ml vs. 4.12±2.05 ng/ml, P<0.001). Patients with locally advanced and metastatic PCa had significantly higher serum EPCA level than those with clinically localized PCa (22.93±5.28 ng/ml and 29.41±8.47 ng/ml vs. 15.17±6.03 ng/ml, P = 0.014 and P<0.001, respectively). Significantly elevated EPCA level was also found in metastatic PCa compared with locally advanced disease (P<0.001). Increased serum EPCA levels were significantly and positively correlated with Gleason score and clinical stage, but not with PSA levels and age. On multivariate analysis, pretreatment serum EPCA level held the most significantly predictive value for the biochemical recurrence and androgen-independent progression among pretreatment variables (HR = 4.860, P<0.001 and HR = 5.418, P<0.001, respectively). Conclusions Serum EPCA level is markedly elevated in PCa. Pretreatment serum EPCA level correlates significantly with the poor prognosis, showing prediction potential for PCa progression.

    BACKGROUND Early allograft dysfunction (EAD) is considered an important complication in liver transplantation. Serum brain natriuretic peptide (BNP) is a marker of cardiac dysfunction related to end-stage liver disease. We investigated the intraoperative change in the serum BNP level and its contribution to EAD after living donor liver transplantation (LDLT). MATERIAL AND METHODS The perioperative data of 104 patients who underwent LDLT were retrospectively reviewed and compared between patients with and without EAD. Serum BNPs were obtained at each phase, and potentially significant factors (P<0.1) were measured by univariate analysis. The intraoperative mean serum BNP level was compared with other predictors using the AUC, and was analyzed for its relationship with EAD by multivariate logistic regression. RESULTS A total of 31 patients (29.8%) developed EAD after LDLT. In all phases, the EAD group showed higher serum BNP levels than the non-EAD group. The serum BNP level at each phase was less accurate than the mean serum BNP level for EAD. The intraoperative mean serum BNP level showed higher predictive accuracy than the Child-Pugh-Turcotte, model for end-stage liver disease (MELD), and D-MELD (donor age × recipient MELD) scores (p<0.05 for all). After multivariate adjustment, intraoperative mean serum BNP level ≥100 pg/mL was identified as an independent risk factor for EAD, along with kidney disease and graft ischemic time. CONCLUSIONS During LDLT, the EAD group showed higher serum BNP levels than the non-EAD group. An intraoperative mean serum BNP level ≥100 pg/mL is independently associated with EAD after LDLT.

    Highlights: Black-Right-Pointing-Pointer Overexpression of Ku86 in human liver cancer was shown by immunohistochemistry. Black-Right-Pointing-Pointer Serum anti-Ku86 was significantly elevated in early hepatocellular carcinoma. Black-Right-Pointing-Pointer Anti-Ku86 may be more sensitive than the conventional markers for early detection. Black-Right-Pointing-Pointer Serum anti-Ku86 significantly decreased after surgical resection of liver tumors. Black-Right-Pointing-Pointer Elevation of serum anti-Ku86 in other non-liver solid tumors was minimal. -- Abstract: Hepatocellular carcinoma (HCC), the predominant form of primary liver cancer, is one of the most common cancers worldwide and the third most common cause of cancer-related death. Imaging studies including ultrasound and computed tomography are recommended for early detection of HCC, but they are operator dependent, costly and involve radiation. Therefore, there is a need for simple and sensitive serum markers for the early detection of hepatocellular carcinoma (HCC). In our recent proteomic studies, a number of proteins overexpressed in HCC tissues were identified. We thought if the serum autoantibodies to these overexpressed proteins were detectable in HCC patients. Of these proteins, we focused on Ku86, a nuclear protein involved in multiple biological processes and aimed to assess the diagnostic value of serum anti-Ku86 in the early detection of HCC. Serum samples were obtained prior to treatment from 58 consecutive patients with early or relatively early hepatitis C virus (HCV)-related HCC and 137 patients with HCV-related liver cirrhosis without evidence of HCC. Enzyme immunoassays were used to measure serum levels of autoantibodies. Serum levels of anti-Ku86 antibodies were significantly elevated in HCC patients compared to those in liver cirrhosis patients (0.41 {+-} 0.28 vs. 0.18 {+-} 0.08 Abs at 450 nm, P < 0001). Setting the cut-off level to give 90% specificity, anti-Ku86 was positive in 60.7% of

    The aim of this study was to investigate the association between maternal iron/zinc serum levels and their nutritional intake in early pregnancy with gestational diabetes. The maternal serum zinc/iron levels were measured in 1,033 healthy singleton pregnant women aged 20-35 between 14 and 20 weeks of gestation, within two groups: namely, normal and gestational diabetes, and participants were followed up to 24-28 weeks of gestation. Food frequency questionnaire was used to assess nutritional intakes of iron/zinc. The main outcome was gestational diabetes screened with the 50-g glucose challenge test and diagnosed with oral glucose tolerance test at 24-28 weeks of gestation. Gestational diabetes occurred in 72 (6.96 %) of 1,033 women in study. There was a statistical relationship between early pregnancy maternal serum iron and gestational diabetes, mean (SD), 143.8 (48.7) vs. 112.5 (83.5) μg/dl, P value of <0.0001. There was no statistical significant difference in zinc levels and iron/zinc nutritional intake between groups. The results remained unchanged after using regression model for adjustment of potential risk factors with an adjusted OR of 1.006 (95 % CI 1.002 to 1.009; P = 0.001) for early pregnancy maternal serum iron to cause gestational diabetes. The receiver-operator characteristic curve identified that a maternal serum iron above 100 μg/dl in early pregnancy is the optimum cutoff value for predicting gestational diabetes, which showed a sensitivity and specificity of 80.6 and 50.7 %, respectively. In conclusion, high maternal serum iron in early pregnancy could increase the risk of gestational diabetes. Also, it could be used as a sensitive and specific predictor for gestational diabetes.

    Prostate cancer screening has led to the diagnosis of localized prostate cancer in increasingly young and sexually active men. Accordingly, the impact of cancer treatment on sexual function is gaining more attention. To prospectively evaluate the impact of radical prostatectomy (RP) on male, female and conjugal sexual function. Patients were prospectively assessed by an urologist and a sexologist before and 6 months after robot-assisted laparoscopic RP (RALP). RALP was performed with uni- or bilateral neurovascular bundle preservation by a single surgeon. Postoperatively, all patients were prescribed tadalafil 20 mg, 3 times a week during 6 months. Male and female sexual functions were evaluated by using the International Index of Erectile Function (IIEF-5), the Female Sexual Function Index (FSFI) and the Lock-Wallace Marital Adjustment Test (MAT). Continuous variables were analyzed with rank-sum and t-tests, as needed, and categorical variables with chi-squared tests. All tests were two-sided, with a P-value ⩽ 0.05 considered significant. Twenty-one couples were included. Mean patient male and female age was 62.4 and 60.7 years, respectively. Bilateral nerve sparing was performed in 12/21 (57%) patients. Median preoperative IIEF-5 was 20/25, corresponding to mild erectile dysfunction (ED). Median preoperative FSFI and MAT were both within normal range (28/36 and 114/158, respectively). Six months following surgery, both IIEF-5 (11/25) and FSFI (25/36) had significantly dropped (P=0.007 and 0.003, respectively). Postoperative decreases in IIEF-5 and FSFI scores were associated within couples. MAT scores (115/158), however, remained unaffected by RALP, showing an unmodified relationship satisfaction postoperatively. Finally, bilateral nerve sparing surgery preserved not only male but also female sexual function. This study shows that the expected short-term post-RALP ED is associated with a worsening of female sexual function, whereas nerve sparing surgery has a

    The aim of this study was to assess changes in serum concentrations of C-reactive protein (CRP), serum amyloid A component (SAA), and haptoglobin (Hp) in bitches with pyometra undergoing ovariohysterectomy that developed postoperative wound infection-related complications. The study revealed that difficulties in postoperative wound healing were induced by infections with Escherichia coli and Staphylococcus spp. leading to re-increased levels of CRP and SAA immediately after surgery and persistently high Hp levels throughout the experiment. Our results indicate that acute-phase proteins in bitches undergoing surgery because of pyometra are useful markers for monitoring the postoperative period. Moreover, they enable prompt therapeutic management once complications develop. PMID:19477501

    Background Interleukin-15 (IL-15) is thought to be involved in the physiopathological mechanisms of RA and it can be detected in the serum and the synovial fluid of inflamed joints in patients with RA but not in patients with osteoarthritis or other inflammatory joint diseases. Therefore, the objective of this work is to analyse whether serum IL-15 (sIL-15) levels serve as a biomarker of disease severity in patients with early arthritis (EA). Methodology and Results Data from 190 patients in an EA register were analysed (77.2% female; median age 53 years; 6-month median disease duration at entry). Clinical and treatment information was recorded systematically, especially the prescription of disease modifying anti-rheumatic drugs. Two multivariate longitudinal analyses were performed with different dependent variables: 1) DAS28 and 2) a variable reflecting intensive treatment. Both included sIL-15 as predictive variable and other variables associated with disease severity, including rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibodies (ACPA). Of the 171 patients (638 visits analysed) completing the follow-up, 71% suffered rheumatoid arthritis and 29% were considered as undifferentiated arthritis. Elevated sIL-15 was detected in 29% of this population and this biomarker did not overlap extensively with RF or ACPA. High sIL-15 levels (β Coefficient [95% confidence interval]: 0.12 [0.06–0.18]; p<0.001) or ACPA (0.34 [0.01–0.67]; p = 0.044) were significantly and independently associated with a higher DAS28 during follow-up, after adjusting for confounding variables such as gender, age and treatment. In addition, those patients with elevated sIL-15 had a significantly higher risk of receiving intensive treatment (RR 1.78, 95% confidence interval 1.18–2.7; p = 0.007). Conclusions Patients with EA displaying high baseline sIL-15 suffered a more severe disease and received more intensive treatment. Thus, sIL-15 may be a biomarker for

    Introduction: Opioids are widely used in conjunction with local anesthetics as they permit the use of lower dose of local anesthetics while providing adequate anesthesia and analgesia. It both provides adequate anesthesia as well as lower drug toxicity neuraxial administration of opioids in conjunction with local anesthetics improves the quality of intraoperative analgesia and prolongs the duration of postoperative analgesia. Bupivacaine is the most commonly used drug for subarachnoid block due to its lesser side effects. The present study was conducted to decrease the overall dose of local anesthetics with opioid combination for urological procedure with respect to quality of anesthesia and recovery with patient's satisfaction. Materials and Methods: The study population was randomly allocated by computer generated table into two groups; Group A: 5 mg 0.5% bupivacaine + 25 mcg and Group B: 5 mg 0.5% bupivacaine + 25 mg butorphanol. Results: Highest level of sensory block was T9 and T8 with the fentanyl group and butorphanol group, respectively. The onset of sensory block was early in fentanyl group than butorphanol group. Duration of both sensory and motor block was significantly higher in butorphanol group. There was no incidence of itching in both groups. There were two patients in fentanyl group and one in butorphanol with hypotension for which injection mephentermine was given. Two patients in fentanyl group complained of nausea and vomiting, for which injection ondansetron was given. One patient complained of pain in fentanyl group for which injection propofol with injection fentanyl was supplemented. Conclusion: Low-dose bupivacaine with butorphanol group was devoid of any side effects in the present study but low dose bupivacaine in addition with fentanyl is superior in terms of early postoperative recovery resulting in early discharge and better outcome in comparison to bupivacaine and butorphanol group, which is beneficial in elderly patients with

    Purpose: To determine the clinical benefit of high-dose early adjuvant radiotherapy (EART) in high-risk prostate cancer (hrCaP) patients submitted to radical retropubic prostatectomy plus pelvic lymphadenectomy. Patients and Methods: The clinical outcome of 334 hrCaP (pT3-4 and/or positive resection margins) node-negative patients submitted to radical retropubic prostatectomy plus pelvic lymphadenectomy before 2004 was analyzed according to the EART dose delivered to the prostatic bed, <70.2 Gy (lower dose, median 66.6 Gy, n = 153) or >=70.2 Gy (median 70.2 Gy, n = 181). Results: The two groups were comparable except for a significant difference in terms of median follow-up (10 vs. 7 years, respectively) owing to the gradual increase of EART doses over time. Nevertheless, median time to prostate-specific antigen (PSA) failure was almost identical, 38 and 36 months, respectively. At univariate analysis, both 5-year biochemical relapse-free survival (bRFS) and disease-free survival (DFS) were significantly higher (83% vs. 71% [p = 0.001] and 94% vs. 88% [p = 0.005], respectively) in the HD group. Multivariate analysis confirmed EART dose >=70 Gy to be independently related to both bRFS (hazard ratio 2.5, p = 0.04) and DFS (hazard ratio 3.6, p = 0.004). Similar results were obtained after the exclusion of patients receiving any androgen deprivation. After grouping the hormone-naive patients by postoperative PSA level the statistically significant impact of high-dose EART on both 5-year bRFS and DFS was maintained only for those with undetectable values, possibly owing to micrometastatic disease outside the irradiated area in case of detectable postoperative PSA values. Conclusion: This series provides strong support for the use of EART doses >=70 Gy after radical retropubic prostatectomy in hrCaP patients with undetectable postoperative PSA levels.

    Purpose: The purpose of this study was to evaluate dose-volume histogram (DVH) predictors for the development of chronic gastrointestinal (GI) complications in cervical cancer patients who underwent radical hysterectomy and postoperative concurrent nedaplatin-based chemoradiation therapy. Methods and Materials: This study analyzed 97 patients who underwent postoperative concurrent chemoradiation therapy. The organs at risk that were contoured were the small bowel loops, large bowel loop, and peritoneal cavity. DVH parameters subjected to analysis included the volumes of these organs receiving more than 15, 30, 40, and 45 Gy (V15-V45) and their mean dose. Associations between DVH parameters or clinical factors and the incidence of grade 2 or higher chronic GI complications were evaluated. Results: Of the clinical factors, smoking and low body mass index (BMI) (<22) were significantly associated with grade 2 or higher chronic GI complications. Also, patients with chronic GI complications had significantly greater V15-V45 volumes and higher mean dose of the small bowel loops compared with those without GI complications. In contrast, no parameters for the large bowel loop or peritoneal cavity were significantly associated with GI complications. Results of the receiver operating characteristics (ROC) curve analysis led to the conclusion that V15-V45 of the small bowel loops has high accuracy for prediction of GI complications. Among these parameters, V40 gave the highest area under the ROC curve. Finally, multivariate analysis was performed with V40 of the small bowel loops and 2 other clinical parameters that were judged to be potential risk factors for chronic GI complications: BMI and smoking. Of these 3 parameters, V40 of the small bowel loops and smoking emerged as independent predictors of chronic GI complications. Conclusions: DVH parameters of the small bowel loops may serve as predictors of grade 2 or higher chronic GI complications after postoperative

    Background Atherosclerosis is a chronic inflammatory disorder, and several studies have demonstrated a positive association between plasma serum amyloid A (SAA) levels and cardiovascular disease risk. The aim of the study was to examine whether SAA has a role in atherogenesis, the underlying basis of most cardiovascular disease. Methods and Results Mice globally deficient in acute-phase isoforms Saa1 and Saa2 (Saa−/−) were crossed to Ldlr−/− mice (Saa−/−Ldlr−/−). Saa−/−Ldlr−/− mice demonstrated a 31% reduction in lesional area in the ascending aorta but not in the aortic root or innominate artery after consuming a high-fat, high-cholesterol Western-type diet for 6 weeks. The lesions were predominantly macrophage foam cells. The phenotype was lost in more mature lesions in mice fed a Western-type diet for 12 weeks, suggesting that SAA is involved in early lesion development. The decreased atherosclerosis in the Saa−/−Ldlr−/− mice occurred despite increased levels of blood monocytes and was independent of plasma lipid levels. SAA is produced predominantly by hepatocytes and macrophages. To determine which source of SAA may have a dominant role in lesion development, bone marrow transplantation was performed. Ldlr−/− mice that received bone marrow from Saa−/−Ldlr−/− mice had slightly reduced ascending aorta atherosclerosis compared with Saa−/−Ldlr−/− mice receiving bone marrow from Ldlr−/− mice, indicating that the expression of SAA by macrophages may have an important influence on atherogenesis. Conclusions The results indicate that SAA produced by macrophages promotes early lesion formation in the ascending aorta. PMID:26187995

    In an attempt to better understand potential biomarkers for, and the role of macrophages in, the development of atherosclerosis, the toxicologic, and any therapeutic pharmacologic effects of carboxymethylated β-glucan, gadolinium chloride, and poloxamer 407 were studied in mice for their capacity to perturb serum lipids, cystatin C, and chitotriosidase-1. Gadolinium and carboxymethylated β-glucan dosed separately to control mice had no effect on serum lipids, whereas carboxymethylated β-glucan, but not gadolinium, exerted a significant (p<0.01) and unexpected hypolipidemic effect in poloxamer 407-induced hyperlipidemic mice. An acute hyperlipidemic state (∼4 days), induced with poloxamer 407 administration alone, resulted in a significant (p<0.01) time-dependent decrease and increase in serum cystatin C and chitotriosidase, respectively. Carboxymethylated β-glucan administration to hyperlipidemic mice significantly (p<0.05) increased the serum concentration of cystatin C, but significantly (p<0.01) decreased chitotriosidase activity, when each was compared to mice treated with poloxamer 407 only. Gadolinium administration caused a significant decrease in serum chitotriosidase activity in both controls (p<0.01) and poloxamer 407-induced hyperlipidemic (p<0.001) mice, but had no effect on the concentration of cystatin C in either controls or poloxamer 407-induced hyperlipidemic mice. Gadolinium administration resulted in both morphological and functional changes to liver macrophages, which included incorporation of excess lipids, especially when simultaneously administered with poloxamer 407. It is suggested that serum cystatin C and chitotriosidase may represent potential early biomarkers for eventual atherosclerosis in the poloxamer 407-induced mouse model of atherogenesis, and that two compounds known to either increase (carboxymethylated β-glucan) or decrease (gadolinium chloride) the number of macrophages in vivo were able to modulate serum

    In the preoperative period ischemic patients show a significant increase in thrombodynamic properties of fibrin clots. It is more than at a half of patients in the presurgical period as in an arterial, and venus blood the spontaneous growth of a clot comes to light that is practically not observed at healthy people. In the early postoperative period ischemic patients demonstrate a general sharp decrease in thrombodynamic properties of fibrin clots, but in arterial blood, as opposed to venous blood, such properties sharply grow. Based on the data obtained it may be concluded that in ischemic patients venous blood levels cannot be used as a judgement for arterial blood fibrin clot properties. PMID:26255313

    Background & Objective Placental abruption, an ischemic placental disorder, complicates about 1 in 100 pregnancies, and is an important cause of maternal and perinatal morbidity and mortality worldwide. Metabolomics holds promise for improving the phenotyping, prediction and understanding of pathophysiologic mechanisms of complex clinical disorders including abruption. We sought to evaluate maternal early pregnancy pre-diagnostic serum metabolic profiles and abnormal vaginal bleeding as predictors of abruption later in pregnancy. Methods Maternal serum was collected in early pregnancy (mean 16 weeks, range 15 to 22 weeks) from 51 abruption cases and 51 controls. Quantitative targeted metabolic profiles of serum were acquired using electrospray ionization liquid chromatography-mass spectrometry (ESI-LC-MS/MS) and the Absolute IDQ® p180 kit. Maternal sociodemographic characteristics and reproductive history were abstracted from medical records. Stepwise logistic regression models were developed to evaluate the extent to which metabolites aid in the prediction of abruption. We evaluated the predictive performance of the set of selected metabolites using a receiver operating characteristics (ROC) curve analysis and area under the curve (AUC). Results Early pregnancy vaginal bleeding, dodecanoylcarnitine/dodecenoylcarnitine (C12 / C12:1), and phosphatidylcholine acyl-alkyl C 38:1 (PC ae C38:1) strongly predict abruption risk. The AUC for these metabolites alone was 0.68, for early pregnancy vaginal bleeding alone was 0.65, and combined the AUC improved to 0.75 with the addition of quantitative metabolite data (P = 0.003). Conclusion Metabolomic profiles of early pregnancy maternal serum samples in addition to the clinical symptom, vaginal bleeding, may serve as important markers for the prediction of abruption. Larger studies are necessary to corroborate and validate these findings in other cohorts. PMID:27300725

    Postoperative anemia is a common finding in patients who undergo major surgery, and it can affect early rehabilitation and the return to daily activities. Allogeneic blood transfusion is still the most widely used method for restoring hemoglobin levels rapidly and effectively. However, the potential risks of transfusions have led to the review of this practice and to a search for alternative measures for treating postoperative anemia. The early administration of intravenous iron appears to improve the evolution of postoperative hemoglobin levels and reduce allogeneic transfusions, especially in patients with significant iron deficiency or anemia. What is not clear is whether this treatment heavily influences rehabilitation and quality of life. There is a lack of well-designed, sufficiently large, randomized prospective studies to determine whether postoperative or perioperative intravenous iron treatment, with or without recombinant erythropoietin, has a role in the recovery from postoperative anemia, in reducing transfusions and morbidity rates and in improving exercise capacity and quality of life.

    Context: Oxidative stress is a major determinant in carcinogenesis and serum total antioxidant capacity (TAC) indirectly reflects the level of oxidative stress. Although oral cancer is the third most frequent cancer in Indian population, there are no standard noninvasive marker for early detection and monitoring therapeutic response in oral cancer patients. Aims: This study was carried out to investigate implications of serum TAC in oral cancer by evaluating pre- and post-operative levels in oral cancer patients. Settings and Designs: It was a prospective single blinded study. Subjects and Methods: Serum TAC was measured using ferric-reducing antioxidant power assay. Pre- and post-operative values were estimated and compared in 30 oral cancer patients who underwent surgery. Statistical Analysis Used: Paired t-test was used to compare pre- and post-operative values. Results: Compared to the normal value, both pre- and post-operative serum TAC were significantly low in oral cancer patients. However, there was no statistically significant difference between pre- and postoperative levels. Conclusions: In this study, low mean serum TAC was detected in oral cancer patients. However, its diagnostic and prognostic significance in oral cancer needs further investigation. PMID:25829792

    Legionella pneumonia can be difficult to diagnose. Existing laboratory tests all have shortcomings, especially in the ability to diagnose Legionnaires' disease (LD) at an early stage of the disease in a specimen that is readily obtainable. The aim of this study was to assess the performance of PCR as a rapid diagnostic method and to compare the results of different PCR assays of serum samples from patients with LD. Samples included 151 serum samples from 68 patients with proven LD and 60 serum samples from 36 patients with respiratory tract infections other than Legionella. PCR assays were based on the 5S rRNA gene, 16S rRNA gene and the mip gene. The samples from patients with infections caused by pathogens other than Legionella all tested negative in PCR. Among the patients with proven LD 54.4 % (37/68) tested positive in 5S rRNA PCR, 52.9 % (36/68) in mip gene PCR and 30.9 % (21/68) in 16S rRNA PCR in the first available serum sample. The association between threshold cycle value in 5S PCR positive serum samples (n=49) and C-reactive protein value was determined, and showed a strong negative correlation (Pearson correlation coefficient r=-0.63, P<0.0001). In addition to existing tests for the diagnosis of LD, detection of Legionella DNA in serum could be a useful tool for early diagnosis of LD caused by any Legionella species and serogroup, and has the potential to provide a diagnosis in a time frame that could affect initial infection management.

    Objective The insulin-pancreatic acinar axis may play a major role in pancreatic function. Amylase is an exocrine enzyme that is produced by pancreatic acinar cells, and low serum amylase levels may be associated with endocrine diseases, such as metabolic syndrome and diabetes. We hypothesized that low serum amylase levels may be associated with impaired islet β cell function in type 2 diabetes. Therefore, we investigated the relationship between the serum amylase levels and islet β cell function in patients with early type 2 diabetes. Methods The cross-sectional study recruited 2327 patients with a mean of 1.71±1.62 years since their diagnosis of type 2 diabetes, and all participants were treated with lifestyle intervention alone. Serum amylase levels, the 75-g oral glucose tolerance test (OGTT) and metabolic risk factors were examined in all participants. The insulin sensitivity index (Matsuda index, ISIMatsuda) and insulin secretion index (ratio of total area-under-the-insulin-curve to glucose-curve, AUCins/glu) were derived from the OGTT. Integrated islet β cell function was assessed by the Insulin Secretion-Sensitivity Index-2 (ISSI-2) (ISIMatsuda multiplied by AUCins/glu). Results Serum amylase levels in the normal range were significantly correlated with ISIMatsuda, AUCins/glu and ISSI-2 (r = 0.203, 0.246 and 0.413, respectively, p<0.001). The association of the serum amylase levels with ISSI-2 (adjusted r = 0.363, p<0.001) was closer than the association with ISIMatsuda (adjusted r = 0.191, p<0.001) and AUCins/glu (adjusted r = 0.174, p<0.001) after adjusting for the anthropometric indices, time since the diagnosis of diabetes, lipid profiles, uric acid levels, estimated glomerular filtration rate, HbA1c levels, smoking and drinking using the partial correlation test. After adjusting for these metabolic risk factors in the multivariate regression analysis with the amylase levels as the dependent variable, ISSI-2 was the major independent contributor to

Previous studies indicate that the level of human endogenous retrovirus type K (group HERV-K(HML-2)) transcription may be increased in human breast tumors. We hypothesized that HERV-K(HML-2) reactivation can serve as a biomarker for early detection of breast cancer. Serum samples were collected from women without cancer (controls) and patients with ductal carcinoma in situ (DCIS) and invasive breast cancer. ELISA assays were employed to detect serum anti-HERV-K(HML-2) antibody titers. RNA was extracted from sera and analyzed by real-time RT-PCR to quantitate the level of HERV-K(HML-2) mRNA. We measured significantly higher serum mRNA and serum antibody titers against HERV-K(HML-2) proteins in women with DCIS and stage I disease than in women without cancer. At optimized cutoffs for the antibody titers, the assay produced an area under the ROC curve (AUC) of 0.89 (95% confidence interval 0.77 to 1.00) for DCIS and of 0.95 (95% confidence interval 0.89 to 1.00) for invasive breast cancer. These AUCs are comparable to those observed for mammograms. We also found that serum HERV-K(HML-2) mRNA tended to be higher in breast cancer patients with a primary tumor who later on developed the metastatic disease than in patients who did not develop cancer metastasis. Our results show that HERV-K(HML-2) antibodies and mRNA are already elevated in the blood at an early stage of breast cancer, and further increase in patients who are at risk of developing a metastatic disease.

    Study Design Retrospective study. Purpose To evaluate the initial fixation using the cortical bone trajectory (CBT) technique for posterior lumbar fusion through assessment of the clear zones around the screws and the risk factors involved. Overview of Literature Postoperative radiolucent zones (clear zones) are an indicator of poor conventional pedicle screw fixation. Methods Between January 2013 and April 2014, 19 patients (8 men and 11 women) underwent posterior lumbar interbody fusion or posterior lumbar fusion using the CBT technique. A total of 109 screws were used for evaluation with measurement of the maximum insertional torque of last two screw rotations. Clear zone-positivity on plain radiographs was investigated 6 months after surgery. The relation between intraoperative insertional torque and clear zone-positivity was investigated by one-way analysis of variance. In addition, the correlation between clear zone-positivity and gender, age (<75 years old or >75 years old), or operative stabilization level (<2 or >3 vertebral levels) was evaluated using the chi-square test. Results Clear zones were observed around six screws (5.50%) in five patients (26.3%). The mean insertional torque (4.00±2.09 inlbs) of clear zone-positive screws was lower than that of clear zone-negative screws (8.12±0.50 in-lbs), but the difference was not significant. There was a significant correlation between clear zone-positivity and operative level of stabilization. Conclusions The low incidence of clear zone-positive screws indicates good initial fixation using the CBT technique. Multilevel fusions may be risk factors for clear zone generation. PMID:26713120

    Abstract Cell-mediated immunity plays an important role in the pathobiology of tuberculosis (TB). The ligands for CXC chemokine receptor 3 (CXCR3) activate the T-helper type 1 lymphocyte pathway. The CXCR3 ligands are reportedly useful clinical markers for the diagnosis and follow-up of TB. The objective of this study was to assess the utility of CXCR3 ligands for evaluating early treatment responses in TB. We recruited 88 patients who underwent antituberculous chemotherapy. The serum levels of interferon (IFN)-γ and the CXCR3 ligands CXCL9 (monokine induced by IFN-γ [MIG]), CXCL10 (IFN-γ-inducible 10-kDa protein [IP-10]), and CXCL11 (IFN-inducible T-cell α chemoattractant [I-TAC]) were measured before and 2 months after the start of treatment. Treatment responses were divided into “fast” and “slow” based on the clinical, radiological, and bacteriological improvement at 2 months. A change in level of 20% or more at 2 months was defined as “significant.” In patients with treatment success, 58 patients exhibited a fast response and 20 patients exhibited a slow response. Treatment failure occurred in 5 patients, and the diagnoses were changed to non-TB diseases in 5 patients. The levels of all CXCR3 ligands significantly decreased in the fast-response group (P < 0.01) but did not decrease in the other groups. IFN-γ levels showed no significant changes. The ability of significant decreases in marker levels to predict a fast response was evaluated. CXCL9 showed a sensitivity of 83%, and CXCL10 showed a specificity of 100%. Use of various combinations of CXCR3 ligands resulted in improvements in sensitivity (88%–93%), while specificity (92%–96%) was similar to that using single CXCR3 ligands. The decreases in CXCR3 ligand levels were less marked in the 2-month Mycobacterium tuberculosis culture-positive group than in the culture-negative group. There were significant differences in treatment outcomes in terms of 2-month culture positivity (P

    Blood-based early detection of breast cancer has recently gained novel momentum, as liquid biopsy diagnostics is a fast emerging field. In this study, we aimed to identify secreted proteins which are up-regulated both in tumour tissue and serum samples of breast cancer patients compared to normal tissue and sera. Based on two independent tissue cohorts (n = 75 and n = 229) and one serum cohort (n = 80) of human breast cancer and healthy serum samples, we characterised AGR3 as a novel potential biomarker both for breast cancer prognosis and early breast cancer detection from blood. AGR3 expression in breast tumours is significantly associated with oestrogen receptor α (P<0.001) and lower tumour grade (P<0.01). Interestingly, AGR3 protein expression correlates with unfavourable outcome in low (G1) and intermediate (G2) grade breast tumours (multivariate hazard ratio: 2.186, 95% CI: 1.008-4.740, P<0.05) indicating an independent prognostic impact. In sera analysed by ELISA technique, AGR3 protein concentration was significantly (P<0.001) elevated in samples from breast cancer patients (n = 40, mainly low stage tumours) compared to healthy controls (n = 40). To develop a suitable biomarker panel for early breast cancer detection, we measured AGR2 protein in human serum samples in parallel. The combined AGR3/AGR2 biomarker panel achieved a sensitivity of 64.5% and a specificity of 89.5% as shown by receiver operating characteristic (ROC) curve statistics. Thus our data clearly show the potential usability of AGR3 and AGR2 as biomarkers for blood-based early detection of human breast cancer. PMID:25875093

    Usually postoperative wounds are kept dry until the stitches are removed. In a prospective randomized study early water contact was allowed in order to test postoperative wound healing in 817 patients operated on for varicose veins. Regardless of whether the wounds were kept dry or had water contact with or without shower foam from the second postoperative day, no infection was registered.

    We assessed the use of guided plasticity training to improve the outcome in the first 6 months after nerve repair. In a multicentre randomized controlled trial, 37 adults with median or ulnar nerve repair at the distal forearm were randomized to intervention, starting the first week after surgery with sensory and motor re-learning using mirror visual feedback and observation of touch, or to a control group with re-learning starting when reinnervation could be detected. The primary outcome at 3 and 6 months post-operatively was discriminative touch (shape texture identification test, part of the Rosen score). At 6 months, discriminative touch was significantly better in the early intervention group. Improvement of discriminative touch between 3 and 6 months was also significantly greater in that group. There were no significant differences in motor function, pain or in the total score. We conclude that early re-learning using guided plasticity may have a potential to improve the outcomes after nerve repair. LEVEL OF EVIDENCE II. PMID:25294735

    Purpose We aimed to see the frequency of concomitant ischemic heart disease (IHD) in Korean patients with abdominal aortic aneurysm (AAA) and to determine risk factors for an early postoperative acute myocardial infarction (PAMI) after elective open or endovascular AAA repair. Methods We retrospectively reviewed a database of patients who underwent elective AAA repair over the past 11 years. Patients were classified into 3 groups: control group; group I, medical IHD treatment; group II, invasive IHD treatment. Rates of PAMI and mortality at 30 days were compiled and compared between groups according to the type of AAA repair. Results Six hundred two elective repairs of infrarenal or juxtarenal AAAs were enrolled in this study. The patients were classified into control group (n = 398, 66.1%), group I (n = 73, 12.1%) and group II (n = 131, 21.8%). PAMI developed more frequently after open surgical repair (OSR) than after endovascular aneurysm repair (EVAR) (5.4% vs. 1.3%, P = 0.012). In OSR patients (n = 373), PAMI developed 2.1% in control group, 18.0% in group I and 7.1% in group II (P < 0.001). In EVAR group (n = 229), PAMI developed 0.6% in control group, 4.3% in group I and 2.2% in group II (P = 0.211). On the multivariable analysis of risk factors of PAMI, PAMI developed more frequently in patients with positive functional stress test. Conclusion The prevalence of concomitant IHD was 34% in Korean AAA patients. The risk of PAMI was significantly higher after OSR compared to EVAR and in patients with IHD compared to control group. Though we found some risk factors for PAMI, these were not applied to postoperative mortality rate. PMID:26942161

    Like many cancers, an early diagnosis of melanoma is fundamental to ensure a good prognosis, although an important proportion of stage I-II patients may still develop metastasis during follow-up. The aim of this work was to discover serum biomarkers in patients diagnosed with primary melanoma that identify those at a high risk of developing metastasis during the follow-up period. Proteomic and mass spectrophotometry analysis was performed on serum obtained from patients who developed metastasis during the first years after surgery for primary tumors and compared with that from patients who remained disease-free for more than 10 years after surgery. Five proteins were selected for validation as prognostic factors in 348 melanoma patients and 100 controls by ELISA: serum amyloid A and clusterin; immune system proteins; the cell adhesion molecules plakoglobin and vitronectin and the antimicrobial protein dermcidin. Compared to healthy controls, melanoma patients have high serum levels of these proteins at the moment of melanoma diagnosis, although the specific values were not related to the histopathological stage of the tumors. However, an analysis based on classification together with multivariate statistics showed that tumor stage, vitronectin and dermcidin levels were associated with the metastatic progression of patients with early-stage melanoma. Although melanoma patients have increased serum dermcidin levels, the REPTree classifier showed that levels of dermcidin <2.98 μg/ml predict metastasis in AJCC stage II patients. These data suggest that vitronectin and dermcidin are potent biomarkers of prognosis, which may help to improve the personalized medical care of melanoma patients and their survival. PMID:27216146

    We measured total serum copper and ceruloplasmin levels in pre- and postmenopausal Stage I and II breast cancer (BC) patients and omnivorous and vegetarian controls. The omnivorous groups included 14 premenopausal women [33 +/- 6 (SD) yrs] and 11 postmenopausal women (57 +/- 5 yrs), and the vegetarian groups were comprised of 12 premenopausal subjects (34 +/- 7 yrs) and 11 postmenopausal subjects (59 +/- 5 yrs). There were 13 premenopausal BC patients (39 +/- 7 yrs) and 10 postmenopausal BC patients (66 +/- 6 yrs). Fasting serum samples were taken on three consecutive days, typically four times in the year. Serum ceruloplasmin levels (g/l) were measured by nephelometry utilizing monoclonal antiserum, and total serum copper levels (mumol/l) were determined by proton-induced X-ray emission analysis. Premenopausal patients had higher serum copper levels than their controls (mean 18.7 vs. 16.6, p less than 0.03). For ceruloplasmin, the postmenopausal BC patients had significantly lower levels than pooled postmenopausal controls (0.309 vs. 0.370, p less than 0.001). The copper-to-ceruloplasmin ratio was significantly higher in the pooled cancer groups than in the pooled control groups (3.69 vs. 3.21, p less than 0.001), with similar patterns in both pre- and postmenopausal classes. This high serum copper-to-ceruloplasmin ratio in BC patients may reflect disordered copper metabolism in this disease, which could also have implications for the origin of, or the response to, the cancer process.

    Objective: Serum gamma-glutamyl transferase (GGT) is a marker for alcohol consumption and hepatobiliary diseases. There are reports on the prognostic role of GGT in coronary artery diseases and stroke. The aim of our study was to identify the potential differences in GGT levels in different types of stroke, and to evaluate the correlation between GGT and 30-day mortality. Method: Patients diagnosed with stroke in emergency department between 01.01.2010 and 30.12.2012 was included in the study. Imaging techniques were used to distinguish between hemorrhagic and ischemic stroke. Ischemic strokes were further classified as either atherosclerotic/lacunar or embolic. Parameters including age, gender, vital signs (systolic and diastolic blood pressure), comorbid diseases (HT, DM, CAD, smoking and alcohol consumption), used medications, previous history of stroke, NIHSS score at the time of admission to emergency department, laboratory parameters (glucose, white blood cell count, hemoglobin, platelet, total cholesterol, creatinine) and duration of hospitalization were recorded. Death records were obtained from patients’ medical records. Results: One thousand eighty six patients were included in the study. GGT levels were not significantly different between ischemic and hemorrhagic strokes (p=0.435). On the other hand, GGT levels in embolic strokes were significantly higher compared to atherosclerotic/lacunar strokes (p=0.001). GGT levels [median 24.50 (16.00-43.00)] in Intensive Care Unit patients were significantly higher compared to GGT level [22.00 (15.00-34.25)] in admitted to service beds patients (p=0.015). Median GGT level of deceased patients was 24.00 (16.00-41.25) and median GGT level of alive patients was 22.00 (15.00-35.00). GGT level of deceased patients was significantly higher compared to GGT levels of alive patients (p=0.048). Conclusion: There was no difference in GGT levels between ischemic and hemorrhagic strokes; however, GGT levels in embolic

    In order to discuss the clinical efficacy of simulation hyperbaric oxygen therapy (HBOT) for severe craniocerebral injury and analyze the related factors of it, 108 patients who transferred to our department during December 2010 - December 2014 for ventilator treatment after operation of severe craniocerebral injury were taken as the subjects of the study. These patients were divided into conventional treatment group and simulation hyperbaric oxygen therapy group to contrast the curative effects. At the meantime, GOS score and length of stay in intensive care unit (ICU) of two groups 6 months after treatment, as well as changes in the indexes of the HBO group during treatment were performed statistical analysis. Then factors affecting prognosis of simulation HBOT were performed regression analysis and principal component analysis. The results showed that when compared to the control group, differences in cases with four GOS score and one GOS score in the treatment group were significant (p<0.05). Jugular venous oxygen saturation (SjvO2), jugular bulb oxygen partial pressure (PjO2), arterial partial pressure of oxygen (PaO2) and arterial oxygen saturation (SaO2) of the simulation HBO group before the first time treatment on the first day and after the first time treatment on the third day were significantly increased, with statistical significance (p<0.05); serum lactic acid (Lac) and blood glucose (Glu) decreased significantly (p<0.05). Prior to and during the first treatment on the first day, jugular bulb pressure (Pj) and central venous pressure (CVP) had no significant difference (p>0.05). Regression analysis indicated that factors affecting prognosis included cerebral contusion, coronary heart disease, hydrocephalus and tracheotomy. Principal component analysis found the factors were hydrocephalus, coronary heart disease, tracheotomy, cerebral contusion, cerebral infarction and glasgow coma scale (GCS) before treatment. Therefore, stimulation HBOT can

    Objective: To investigate the effect of rosuvastatin dose-loading on serum levels of lectin-like oxidized low-density lipoprotein receptor-1 (Lox-1) and high-sensitivity c-reactive protein (hs-CRP) and postoperative prognosis in patients with diabetes and non-ST segment elevation acute coronary syndromes (NSTEACS) undergoing selected percutaneous coronary intervention (PCI). Methods: A total of 72 patients with diabetes and NSTEACS were randomized to either the group treated with 20 mg rosuvastatin 12 hours prior to PCI with a second dose administered just before PCI (n = 33), or a control group treated with standard method according guideline (n = 39). Serum levels of sLox-1, hs-CRP, CK-MB, and cTnI were measured prior to PCI, and at 24 hours and 30 days after PCI. The 30-day incidence of major adverse cardiac events (MACE) was recorded in both groups. Results: Compared to pre-PCI, serum levels of sLox-1 and hs-CRP of the two groups were increased at 24 hours after PCI (P < 0.05); the levels of CK-MB and cTnI were also improved (P < 0.01); however, the ascended values of sLox-1, hs-CRP, CK-MB, and cTnI were significantly lower in the loading-dose rosuvastatin-treated group than in the control-treated group. Serum levels of sLox-1 and hs-CRP were higher in the loading-dose rosuvastatin-treated group than in the control-treated group at 30 days after PCI (P < 0.05); compared to pre-PCI, the levels of TC and LDL-C were not changed at 24 hours after PCI (P > 0.05) until 30 days after PCI (P < 0.05), but there were no difference between the two groups. The levels of ALT and Scr had no significant difference between the two groups before and after PCI; the 30-day incidence of MACE occurred in 6.06% of patients in the loading-dose rosuvastatin-treated group and in 23.08% of patients in the control-treated group (P < 0.05). Conclusion: The therapy of dose-loading rosuvastatin for patients with diabetes and non-ST segment elevation acute coronary syndromes undergoing

    AIMS: Pregnancies achieved by in vitro fertilization (IVF) are at increased risk of adverse outcome. The main objective of this study was to evaluate the predictive value of β-human chorionic gonadotrophin (β-HCG) and age of the patient for the successful outcome in IVF. MATERIALS AND METHODS: A retrospective study was done in 139 pregnancies after IVF at single IVF center from June 2007 to July 2012. The age of the patient and initial serum values of β-HCG on day 14 of embryo transfer were correlated with ongoing pregnancy (>12 weeks gestation). RESULTS: The β-HCG level on day 14 of more than 347 mIU/ml has a sensitivity of 72.2% and specificity of 73.6% in prediction of pregnancy beyond 12 weeks period of gestation. Positive likelihood ratio (LR) is 2.74 and negative LR is 0.37, (receiver operating characteristic area = 0.79). DISCUSSION: In IVF cycles, there is a lot of stress on the couples while the cycle is going on. There was a positive correlation between the higher values of early serum β-HCG levels and ongoing pregnancy. Hence, it can be used as an independent predictor of a successful outcome of IVF cycle. CONCLUSION: We concluded from our study that early serum β-HCG can be used as a predictor of a successful outcome in IVF. PMID:24672163

    Background. Low body mass index (BMI) at antiretroviral therapy (ART) initiation is associated with early mortality, but the etiology is not well understood. We hypothesized that low pretreatment serum phosphate, a critical cellular metabolism intermediate primarily stored in skeletal muscle, may predict mortality within the first 12 weeks of ART. Methods. We prospectively studied 352 HIV-infected adults initiating ART in Lusaka, Zambia to estimate the odds of death for each 0.1 mmol/L decrease in baseline phosphate after adjusting for established predictors of mortality. Results. The distribution of phosphate values was similar across BMI categories (median value 1.2 mmol/L). Among the 145 participants with BMI <18.5 kg/m(2), 28 (19%) died within 12 weeks. Lower pretreatment serum phosphate was associated with increased mortality (odds ratio (OR) 1.24 per 0.1 mmol/L decrement, 95% CI: 1.05 to 1.47; P = 0.01) after adjusting for sex, age, and CD4(+) lymphocyte count. A similar relationship was not observed among participants with BMI ≥18.5 kg/m(2) (OR 0.96, 95% CI: 0.76 to 1.21; P = 0.74). Conclusions. The association of low pretreatment serum phosphate level and early ART mortality among undernourished individuals may represent a variant of the refeeding syndrome. Further studies of cellular metabolism in this population are needed.

    Minimally invasive lumbar interbody fusion (MILIF) offers potential for reduced operative morbidity and earlier recovery compared with open procedures for patients with degenerative lumbar disorders (DLD). Firm conclusions about advantages of MILIF over open procedures cannot be made because of limited number of large studies of MILIF in a real-world setting. Clinical effectiveness of MILIF in a large, unselected real-world patient population was assessed in this Prospective, monitored, international, multicenter, observational study. Objective: To observe and document short-term recovery after minimally invasive interbody fusion for DLD. Materials and Methods: In a predefined 4-week analysis from this study, experienced surgeons (≥30 MILIF surgeries pre-study) treated patients with DLD by one- or two-level MILIF. The primary study objective was to document patients’ short-term post-interventional recovery (primary objective) including back/leg pain (visual analog scale [VAS]), disability (Oswestry Disability Index [ODI]), health status (EQ-5D) and Patient satisfaction. Results: At 4 weeks, 249 of 252 patients were remaining in the study; the majority received one-level MILIF (83%) and TLIF was the preferred approach (94.8%). For one-level (and two-level) procedures, surgery duration was 128 (182) min, fluoroscopy time 115 (154) sec, and blood-loss 164 (233) mL. Time to first ambulation was 1.3 days and time to study-defined surgery recovery was 3.2 days. Patients reported significantly (P < 0.0001) reduced back pain (VAS: 2.9 vs 6.2), leg pain (VAS: 2.5 vs 5.9), and disability (ODI: 34.5% vs 45.5%), and a significantly (P < 0.0001) improved health status (EQ-5D index: 0.61 vs 0.34; EQ VAS: 65.4 vs 52.9) 4 weeks postoperatively. One adverse event was classified as related to the minimally invasive surgical approach. No deep site infections or deaths were reported. Conclusions: For experienced surgeons, MILIF for DLD demonstrated early benefits (short time to

    Effective triage of dengue patients early in the disease course for in- or out-patient management would be useful for optimal healthcare resource utilization while minimizing poor clinical outcome due to delayed intervention. Yet, early prognosis of severe dengue is hampered by the heterogeneity in clinical presentation and routine hematological and biochemical measurements in dengue patients that collectively correlates poorly with eventual clinical outcome. Herein, untargeted liquid-chromatography mass spectrometry metabolomics of serum from patients with dengue fever (DF) and dengue hemorrhagic fever (DHF) in the febrile phase (<96 h) was used to globally probe the serum metabolome to uncover early prognostic biomarkers of DHF. We identified 20 metabolites that are differentially enriched (p<0.05, fold change >1.5) in the serum, among which are two products of tryptophan metabolism-serotonin and kynurenine. Serotonin, involved in platelet aggregation and activation decreased significantly, whereas kynurenine, an immunomodulator, increased significantly in patients with DHF, consistent with thrombocytopenia and immunopathology in severe dengue. To sensitively and accurately evaluate serotonin levels as prognostic biomarkers, we implemented stable-isotope dilution mass spectrometry and used convalescence samples as their own controls. DHF serotonin was significantly 1.98 fold lower in febrile compared to convalescence phase, and significantly 1.76 fold lower compared to DF in the febrile phase of illness. Thus, serotonin alone provided good prognostic utility (Area Under Curve, AUC of serotonin = 0.8). Additionally, immune mediators associated with DHF may further increase the predictive ability than just serotonin alone. Nine cytokines, including IFN-γ, IL-1β, IL-4, IL-8, G-CSF, MIP-1β, FGF basic, TNFα and RANTES were significantly different between DF and DHF, among which IFN-γ ranked top by multivariate statistics. Combining serotonin and IFN-γ improved

    The objective of this study was to determine the concentration of serum l-arginine in healthy pregnant women and infant cord blood and to compare them with those in patients with pregnancy-induced hypertension (PIH). The serum concentration of l-arginine in normal pregnant women at early gestation (n = 186) was determined and analyzed based on maternal factors such as the age, pre-pregnancy body mass index (BMI), smoking and alcohol habits before pregnancy. Similarly, the concentration of cord blood of the newborns (n = 142) was also analyzed. These values were compared with those in the PIH group (n = 21). The potential risk factors for PIH were also estimated. The serum concentration of l-arginine at early gestation in normal pregnant women (88.65 ± 19.96 µM) was not affected by the maternal age and BMI before pregnancy. A lower l-arginine concentration at early gestation (<70 µM) significantly elevated PIH risk [adjusted odds ratio (OR) = 4.26, 95% CI 1.29–14.50]. In addition, either women with large body mass before pregnancy (BMI>25 kg/m2) or primipara women also showed a significant association with PIH risk [adjusted OR = 10.55 (2.95–40.68); 5.25 (1.72–19.15), respectively]. In conclusion, a lower l-arginine concentration at early gestation, overweight before pregnancy (BMI>25 kg/m2) and primipara could predict to the development of PIH. PMID:26236104

    The objective of this study was to determine the concentration of serum l-arginine in healthy pregnant women and infant cord blood and to compare them with those in patients with pregnancy-induced hypertension (PIH). The serum concentration of l-arginine in normal pregnant women at early gestation (n = 186) was determined and analyzed based on maternal factors such as the age, pre-pregnancy body mass index (BMI), smoking and alcohol habits before pregnancy. Similarly, the concentration of cord blood of the newborns (n = 142) was also analyzed. These values were compared with those in the PIH group (n = 21). The potential risk factors for PIH were also estimated. The serum concentration of l-arginine at early gestation in normal pregnant women (88.65 ± 19.96 µM) was not affected by the maternal age and BMI before pregnancy. A lower l-arginine concentration at early gestation (<70 µM) significantly elevated PIH risk [adjusted odds ratio (OR) = 4.26, 95% CI 1.29-14.50]. In addition, either women with large body mass before pregnancy (BMI>25 kg/m(2)) or primipara women also showed a significant association with PIH risk [adjusted OR = 10.55 (2.95-40.68); 5.25 (1.72-19.15), respectively]. In conclusion, a lower l-arginine concentration at early gestation, overweight before pregnancy (BMI>25 kg/m(2)) and primipara could predict to the development of PIH.

    Knee osteoarthritis (OA) is a leading cause of physical disability. At the early stage of knee OA, the increase in synovial fluid cytokine concentrations could contribute to the pathogenesis of OA by degrading articular cartilage. It is unknown, however, if inflammatory cytokines increase systemically at the early or advanced stage of knee OA. The systemic increase of inflammatory cytokines could be detrimental to the endogenous status of micronutrients that protect against excessive inflammation and cytokine-mediated events. The purpose of this study was to test the hypothesis that an increase in serum cytokines associate with a decrease in circulating micronutrients in subjects with early compared to advanced knee OA. Advanced knee OA subjects (n=14) displayed radiographic, pain, and muscular weakness symptoms of knee OA. Early knee OA subjects (n=14) were matched (age, gender, and body mass index) to the advanced OA group and displayed one or two of the aforementioned symptoms of knee OA. Inflammatory cytokines, vitamins C (ascorbic acid), D (25-hydroxyvitamin D), and E (α- and γ-tocopherols), and β-carotene were measured in fasting blood samples. In the early OA group, serum tumor necrosis factor (TNF)-α, interleukin (IL)-5, IL-6, IL-12, and IL-13 concentrations were significantly (all p<0.05) increased. Circulating ascorbic acid, 25-hydroxyvitamin D, α- and γ-tocopherol's, and β-carotene concentrations were not significantly different between groups. Based on these preliminary results, we conclude that the systemic increase of inflammatory cytokines is not associated with a decrease in circulating micronutrients in subjects with early compared to advanced knee OA.

  13. Protein Kinase Cδ Blocks Immediate-Early Gene Expression in Senescent Cells by Inactivating Serum Response Factor

    Fibroblasts lose the ability to replicate in response to growth factors and become unable to express growth-associated immediate-early genes, including c-fos and egr-1, as they become senescent. The serum response factor (SRF), a major transcriptional activator of immediate-early gene promoters, loses the ability to bind to the serum response element (SRE) and becomes hyperphosphorylated in senescent cells. We identify protein kinase C delta (PKCδ) as the kinase responsible for inactivation of SRF both in vitro and endogenously in senescent cells. This is due to a higher level of PKCδ activity as cells age, production of the PKCδ catalytic fragment, and its nuclear localization in senescent but not in low-passage-number cells. The phosphorylation of T160 of SRF by PKCδ in vitro and in vivo led to loss of SRF DNA binding activity. Both the PKCδ inhibitor rottlerin and ectopic expression of a dominant negative form of PKCδ independently restored SRE-dependent transcription and immediate-early gene expression in senescent cells. Modulation of PKCδ activity in vivo with rottlerin or bistratene A altered senescent- and young-cell morphology, respectively. These observations support the idea that the coordinate transcriptional inhibition of several growth-associated genes by PKCδ contributes to the senescent phenotype. PMID:15282327

    Purpose: A nomogram is a predictive statistical model that generates the continuous probability of a clinical event such as death or recurrence. The aim of the study was to construct a nomogram to predict 5-year overall survival after postoperative radiation therapy for stage IB to IIA cervical cancer. Methods and Materials: The clinical data from 1702 patients with early-stage cervical cancer, treated at 10 participating hospitals from 1990 to 2011, were reviewed to develop a prediction nomogram based on the Cox proportional hazards model. Demographic, clinical, and pathologic variables were included and analyzed to formulate the nomogram. The discrimination and calibration power of the model was measured using a concordance index (c-index) and calibration curve. Results: The median follow-up period for surviving patients was 75.6 months, and the 5-year overall survival probability was 87.1%. The final model was constructed using the following variables: age, number of positive pelvic lymph nodes, parametrial invasion, lymphovascular invasion, and the use of concurrent chemotherapy. The nomogram predicted the 5-year overall survival with a c-index of 0.69, which was superior to the predictive power of the International Federation of Gynecology and Obstetrics (FIGO) staging system (c-index of 0.54). Conclusions: A survival-predicting nomogram that offers an accurate level of prediction and discrimination was developed based on a large multi-center study. The model may be more useful than the FIGO staging system for counseling individual patients regarding prognosis.

    Problem Need to improve the efficiency of postoperative pain management by early switching from intravenous to oral acetaminophen. Design Implementation of local guidelines aimed at improving nurses' and doctors' behaviour. A controlled, prospective, before and after study evaluated its impact on appropriateness and costs. Background and setting Orthopaedic surgery department (intervention) and all other surgical departments (control) of a university hospital. Five anaesthetists and 30 nurses of orthopaedic department participated in study. Key measures for improvement Reducing number of acetaminophen injections per patient, reducing consumption of acetaminophen injections; cost savings over a one year period. Strategies for improvement Multifaceted intervention included a local consensus process, short educational presentation, poster displayed in all nurses' offices, and feedback of practices six months after implementation of guidelines. Effects of change Mean number of acetaminophen injections per patient decreased from 6.81 before intervention to 2.36 six months after. Monthly consumption of acetaminophen injections per 100 patients decreased by 320.9 (95% confidence interval 192.4 to 449.4) in intervention department and remained unchanged in control departments. Annual cost reduction was projected to be £15 100. Lessons learnt Simple and locally implemented guidelines can improve practices and cut costs. Educational interventions can improve professionals' behaviour when they are based on actual working practices, use interactive techniques such as discussion groups, and are associated with other effective implementation strategies.

    Early-life adversity is associated with an enhanced risk for adult psychopathology. Psychiatric disorders such as depression exhibit comorbidity for metabolic dysfunction, including obesity and diabetes. However, it is poorly understood whether, besides altering anxiety and depression-like behaviour, early stress also evokes dysregulation of metabolic pathways and enhances vulnerability for metabolic disorders. We used the rodent model of the early stress of maternal separation (ES) to examine the effects of early stress on serum metabolites, insulin-like growth factor (IGF)-1 signalling, and muscle mitochondrial content. Adult ES animals exhibited dyslipidaemia, decreased serum IGF1 levels, increased expression of liver IGF binding proteins, and a decline in the expression of specific metabolic genes in the liver and muscle, including Pck1, Lpl, Pdk4 and Hmox1. These changes occurred in the absence of alterations in body weight, food intake, glucose tolerance, insulin tolerance or insulin levels. ES animals also exhibited a decline in markers of muscle mitochondrial content, such as mitochondrial DNA levels and expression of TFAM (transcription factor A, mitochondrial). Furthermore, the expression of several genes involved in mitochondrial function, such as Ppargc1a, Nrf1, Tfam, Cat, Sesn3 and Ucp3, was reduced in skeletal muscle. Adult-onset chronic unpredictable stress resulted in overlapping and distinct consequences from ES, including increased circulating triglyceride levels, and a decline in the expression of specific metabolic genes in the liver and muscle, with no change in the expression of genes involved in muscle mitochondrial function. Taken together, our results indicate that a history of early adversity can evoke persistent changes in circulating IGF-1 and muscle mitochondrial function and content, which could serve to enhance predisposition for metabolic dysfunction in adulthood.

    Postoperative pain is a very important issue for several patients. Indifferent of the surgery type or method, pain management is very necessary. The relief from suffering leads to early mobilization, less hospital stay, reduced hospital costs, and increased patient satisfaction. An individual approach should be applied for pain control, rather than a fix dose or drugs. Additionally, medical, psychological, and physical condition, age, level of fear or anxiety, surgical procedure, personal preference, and response to agents given should be taken into account. The major goal in the management of postoperative pain is minimizing the dose of medications to lessen side effects while still providing adequate analgesia. Again a multidisciplinary team approach should be pursued planning and formulating a plan for pain relief, particularly in complicated patients, such as those who have medical comorbidities. These patients might appear increase for analgesia-related complications or side effects. PMID:25774311

    Novel blood-based screening tests are strongly desirable for early detection of colorectal cancer (CRC). We aimed to identify and evaluate autoantibodies against tumor-associated antigens as biomarkers for early detection of CRC. 380 clinically identified CRC patients and samples of participants with selected findings from a cohort of screening colonoscopy participants in 2005–2013 (N=6826) were included in this analysis. Sixty-four serum autoantibody markers were measured by multiplex bead-based serological assays. A two-step approach with selection of biomarkers in a training set, and validation of findings in a validation set, the latter exclusively including participants from the screening setting, was applied. Anti-MAGEA4 exhibited the highest sensitivity for detecting early stage CRC and advanced adenoma. Multi-marker combinations substantially increased sensitivity at the price of a moderate loss of specificity. Anti-TP53, anti-IMPDH2, anti-MDM2 and anti-MAGEA4 were consistently included in the best-performing 4-, 5-, and 6-marker combinations. This four-marker panel yielded a sensitivity of 26% (95% CI, 13–45%) for early stage CRC at a specificity of 90% (95% CI, 83–94%) in the validation set. Notably, it also detected 20% (95% CI, 13–29%) of advanced adenomas. Taken together, the identified biomarkers could contribute to the development of a useful multi-marker blood-based test for CRC early detection. PMID:26909861

    The currently prescribed tests for asthma diagnosis require compulsory patient compliance, and are usually not sensitive to mild asthma. Development of an objective test using minimally invasive samples for diagnosing and monitoring of the response of asthma may help better management of the disease. Raman spectroscopy (RS) has previously shown potential in several biomedical applications, including pharmacology and forensics. In this study, we have explored the feasibility of detecting asthma and determining treatment response in asthma patients, through RS of serum. Serum samples from 44 asthma subjects of different grades (mild, moderate, treated severe and untreated severe) and from 15 reference subjects were subjected to Raman spectroscopic analysis and YKL-40 measurements. The force expiratory volume in 1 second (FEV1) values were used as gold standard and the serum YKL-40 levels were used as an additional parameter for diagnosing the different grades of asthma. For spectral acquisition, serum was placed on a calcium fluoride (CaF2) window and spectra were recorded using Raman microprobe. Mean and difference spectra comparisons indicated significant differences between asthma and reference spectra. Differences like changes in protein structure, increase in DNA specific bands and increased glycosaminoglycans-like features were more prominent with increase in asthma severity. Multivariate tools using Principal-component-analysis (PCA) and Principal-component based-linear-discriminant analysis (PC-LDA) followed by Leave-one-out-cross-validation (LOOCV), were employed for data analyses. PCA and PC-LDA results indicate separation of all asthma groups from the reference group, with minor overlap (19.4%) between reference and mild groups. No overlap was observed between the treated severe and untreated severe groups, indicating that patient response to treatment could be determined. Overall promising results were obtained, and a large scale validation study on

    Highlights: •Twenty ulcerative colitis patients and nineteen healthy controls were enrolled. •Increased 3-hydroxybutyrate, glucose, phenylalanine, and decreased lipid were found. •We report early stage diagnosis of ulcerative colitis using NMR-based metabolomics. -- Abstract: Ulcerative colitis (UC) has seriously impaired the health of citizens. Accurate diagnosis of UC at an early stage is crucial to improve the efficiency of treatment and prognosis. In this study, proton nuclear magnetic resonance ({sup 1}H NMR)-based metabolomic analysis was performed on serum samples collected from active UC patients (n = 20) and healthy controls (n = 19), respectively. The obtained spectral profiles were subjected to multivariate data analysis. Our results showed that consistent metabolic alterations were present between the two groups. Compared to healthy controls, UC patients displayed increased 3-hydroxybutyrate, β-glucose, α-glucose, and phenylalanine, but decreased lipid in serum. These findings highlight the possibilities of NMR-based metabolomics as a non-invasive diagnostic tool for UC.

    Background: Surface enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF) is an approach to biomarker discovery that combines chromatography and mass spectrometry. We aimed to consider the efficacy of Bc1, Bc2, and Bc3 serum biomarkers on early detection of breast cancer (BC) in this study. Study Design: In this prospective study, 91 patients who were admitted to our hospital between January 2007 and July 2008 were included. Serum samples from 91 women were stored at -80 °C until use. The cancer group included 27 cases of BC. The benign breast disease group included 24 women with benign breast diseases and control group 37 age-matched apparently healthy women. The data obtained for these three groups of patients was worked out for each serum biomarker (Bc1, Bc2, and Bc3) by using SELDI-TOF individually and compared with each other separately and evaluated statistically. Results: Bc2 possesses the highest individual diagnostic power. Bc2 was statistically significant in comparison between the malignant disease group, control group and benign disease group. Bc1 was statistically significant in the malignant disease group compared to control group as well as in the benign disease group compared to control group. Thus Bc1, rather than showing malignant progression, it shows tumoral progression or inflammatory process. Bc3 was found upregulated in all malignant cases; however, it was not statistically significant compared to the benign disease group or the control group. Conclusions: It has been shown that Bc2 profiles might be useful in clinical practice to improve BC diagnosis. However none of the proteomics reach reasonable AUC values for the discrimination of the BC. Additional confirmation in larger and similarly-designed prospective studies is needed to consider of the efficacy of Bc1 and Bc2 in early diagnosis of the BC. PMID:21326957

    Prostate cancer is the second most common cancer and the second leading cause of cancer death in men. However, prostate cancer can be effectively treated and cured, if it is diagnosed in its early stages when the tumor is still confined to the prostate. Combined with the digital rectal examination, the PSA test has been widely used to detect prostate cancer. But, the PSA screening method for early detection of prostate cancer is not reliable due to the high prevalence of false positive and false negative results. Epigenetic alterations including hypermethylation of gene promoters are believed to be the early events in neoplastic progression and thus these methylated genes can serve as biomarkers for the detection of cancer from clinical specimens. This review discusses DNA methylation of several gene promoters during prostate carcinogenesis and evaluates the usefulness of monitoring methylated DNA sequences, such as GSTP1, RASSF1A, RARβ2 and galectin-3, for early detection of prostate cancer in tissue biopsies, serum and urine.

    Studies recently showed that intratracheal (IT) instillation of Libby amphibole (LA) increases circulating acute-phase proteins (APP; α-2 macroglobulin, A2M; and α-1 acid glycoprotein, AGP) and inflammatory biomarkers (osteopontin and lipocalin) in rats. In this study, objectives were to (1) compare changes in biomarkers of rats after instillation of different naturally occurring asbestos (NOA) minerals including LA, Sumas Mountain chrysotile (SM), El Dorado Hills tremolite (ED), and Ontario ferroactinolite cleavage fragments (ON), and (2) examine biomarkers after subchronic LA or amosite inhalation exposure. Rat-respirable fractions (aerodynamic diameter approximately 2.5 μm) prepared by water elutriation were delivered via a single IT instillation at doses of 0, 0.5, and 1.5 mg/rat in male F344 rats. Nose-only inhalation exposures were performed at 0, 1, 3.3, and 10 mg/m(3) for LA and at 3.3 mg /m(3) for amosite, 6h/d, 5 d/wk for 13 wk. Inflammation, metabolic syndrome, and cancer biomarkers were analyzed in the serum for up to 18 mo. IT instillation of some asbestos materials significantly increased serum AGP and A2M but to a varying degree (SM = LA > ON = ED). Numerical increases in interleukin (IL)-6 and osteopontin occurred in rats instilled with SM. SM and ED also elevated leptin and insulin at 15 mo, suggesting potential metabolic effects. LA inhalation tended to raise A2M at d 1 but not cytokines. Serum mesothelin appeared to elevate after 18 mo of LA inhalation. These results suggest that the lung injury induced by high levels of asbestos materials may be associated with systemic inflammatory changes and predisposition to insulin resistance.

    Inadequately treated pain is a major cause of unanticipated hospital admissions after ambulatory surgery. The ability to provide adequate pain relief by simple methods that are readily available to the day-care patient in his or her home environment is one of the major challenges for providers of ambulatory surgery and anesthesia. The increasing number of extensive and painful surgical procedures (e.g., laparoscopic cholecystectomy, laminectomy, knee construction, hysterectomies) being undertaken on an ambulatory basis presents new challenges with respect to acute postoperative pain. Hence the availability of more sophisticated and effective treatment modalities, such as ambulatory PCA and continuous local and regional anesthetic blocks, with minimal side effects, are necessary to optimize the benefits of ambulatory surgery for both patient and health care provider. However, outcome studies are needed to evaluate the effect of these newer therapeutic approaches with respect to postoperative side effects and other important recovery parameters. Recent studies suggest that factors other than pain per se must be controlled to reduce postoperative morbidity and facilitate the recovery process. Not surprisingly, the anesthetic technique can influence analgesic requirement in the early postoperative period. Although oral analgesic agents will continue to play an important role, the adjunctive use of local anesthetic agents is likely to assume an even greater role in the future. Use of drug combinations (e.g., opiates and local anesthetics, opiates and NSAIDs) may provide improved analgesia with fewer side effects. Finally, safer and simpler analgesic delivery systems are needed to improve our ability to provide cost-effective pain relief after ambulatory surgery. In conclusion, as a result of our enhanced understanding of the mechanisms of acute pain and the physiological basis of nociception, the provision of "stress-free" anesthesia with minimal postoperative

    After tibialis posterior tendon transfer surgery for foot-drop correction, the foot is traditionally immobilised for several weeks. To test the feasibility of early mobilisation after this procedure in patients with Hansen's disease, 21 consecutive patients received active mobilisation of the transfer starting on the 5th postoperative day. Transfer insertion strength was enhanced by Pulvertaft weave. The results were compared with a historical cohort of 21 patients receiving 4 weeks of immobilisation. The primary outcomes were active dorsiflexion, active plantar flexion and total active motion at the ankle, tendon-insertion pullout and time until discharge from rehabilitation with independent walking without aid. Assessments at discharge from rehabilitation and the last clinical follow-up at more than 1 year were compared between both groups. The Student's t-test was used to compare data between the groups, and 95% confidence interval of the difference between groups was determined. A p-value of 0.05 was considered statistically significant. The average follow-up was 22 months for both groups. There was no incidence of insertion pullout of the tendon transfer in either group. In addition, there was no difference in active dorsiflexion angle between the groups at discharge (mean difference: 2.2 degrees, p=0.22) and final assessment (mean difference: 2.3 degrees, p=0.42). The plantar flexion angles were similar in both groups at discharge (mean difference: 0.5 degrees, p=0.86) and final assessment (mean difference: 0.5 degrees, p=0.57). In addition, there was no difference in total active motion between the groups at discharge (mean difference: 2 degrees, p=0.54) and final assessment (mean difference: 1 degrees, p=0.49). The patients were discharged from rehabilitation with independent walking at 44.04+/-7.9 days after surgery in the mobilisation group compared to 57.07+/-2.3 days in the immobilisation group. This indicates a significant difference in morbidity (mean

    Aim. To investigate whether there is a correlation between early dental implant failure and low serum levels of vitamin D. Methods. All patients treated with dental implants in a single centre, in the period 2003–2015, were considered for enrollment in this study. The main outcome was early implant failure. The influence of patient-related variables on implant survival was calculated using the Chi-square test. Results. 822 patients treated with 1625 implants were selected for this study; 27 early failures (3.2%) were recorded. There was no link between gender, age, smoking, history of periodontitis, and an increased incidence of early failures. Statistical analysis reported 9 early failures (2.2%) in patients with serum levels of vitamin D > 30 ng/mL, 16 early failures (3.9%) in patients with levels between 10 and 30 ng/mL, and 2 early failures (9.0%) in patients with levels <10 ng/mL. Although there was an increasing trend in the incidence of early implant failures with the worsening of vitamin D deficiency, the difference between these 3 groups was not statistically significant (P = 0.15). Conclusions. This study failed in proving an effective link between low serum levels of vitamin D and an increased risk of early implant failure. Further studies are needed to investigate this topic.

    It is known that anterior cruciate ligament (ACL) reconstruction needs to be combined with detailed postoperative rehabilitation in order for patients to return to their pre-injury activity levels, and that the rehabilitation process is as important as the reconstruction surgery. Literature studies focus on how early in the postoperative ACL rehabilitation period rehabilitation modalities can be initiated. Despite the sheer number of studies on this topic, postoperative ACL rehabilitation protocols have not been standardized yet. Could common, "ossified" knowledge or modalities really prove themselves in the literature? Could questions such as "is postoperative brace use really necessary?", "what are the benefits of early restoration of the range of motion (ROM)?", "to what extent is neuromuscular electrical stimulation (NMES) effective in the protection from muscular atrophy?", "how early can proprioception training and open chain exercises begin?", "should strengthening training start in the immediate postoperative period?" be answered for sure? My aim is to review postoperative brace use, early ROM restoration, NMES, proprioception, open/closed chain exercises and early strengthening, which are common modalities in the very comprehensive theme of postoperative ACL rehabilitation, on the basis of several studies (Level of Evidence 1 and 2) and to present the commonly accepted ways they are presently used. Moreover, I have presented the objectives of postoperative ACL rehabilitation in tables and recent miscellaneous studies in the last chapter of the paper.

Could questions such as “is postoperative brace use really necessary?”, “what are the benefits of early restoration of the range of motion (ROM)?”, “to what extent is neuromuscular electrical stimulation (NMES) effective in the protection from muscular atrophy?”, “how early can proprioception training and open chain exercises begin?”, “should strengthening training start in the immediate postoperative period?” be answered for sure? My aim is to review postoperative brace use, early ROM restoration, NMES, proprioception, open/closed chain exercises and early strengthening, which are common modalities in the very comprehensive theme of postoperative ACL rehabilitation, on the basis of several studies (Level of Evidence 1 and 2) and to present the commonly accepted ways they are presently used. Moreover, I have presented the objectives of postoperative ACL rehabilitation in tables and recent miscellaneous studies in the last chapter of the paper. PMID:25232521

    Alzheimer's disease (AD) is the most common fatal neurodegenerative disease affecting the elderly worldwide. There is an urgent need to identify novel biomarkers of early AD. This study aims to search for potential early protein biomarkers in serum from a triple transgenic (PS1M146V/APPSwe/TauP301L) mouse model. Proteomic analysis via two-dimensional fluorescence difference gel electrophoresis was performed on serum samples from wild-type (WT) and triple transgenic mice that were treated with or without coenzyme Q10 (CoQ10) (800 mg/kg body weight/day), a powerful endogenous antioxidant displaying therapeutic benefits against AD pathology and cognitive impairment in multiple AD mouse models, for a period of three months beginning at two months of age. A total of 15 differentially expressed serum proteins were identified between the WT and AD transgenic mice. The administration of CoQ10 was found to alter the changes in the differentially expressed serum proteins by upregulating 10 proteins and down-regulating 10 proteins. Among the proteins modulated by CoQ10, clusterin and α-2-macroglobulin were validated via ELISA assay. These findings revealed significant changes in serum proteins in the AD mouse model at an early pathological stage and demonstrated that administration of CoQ10 could modulate these changes in serum proteins. Our study suggested that these differentially expressed serum proteins could serve as potential protein biomarkers of early AD and that screening for potential candidate AD therapeutic drugs and monitoring of therapeutic effects could be performed via measurement of the changes in these differentially expressed serum proteins.

    Emerging evidence suggests that minor changes in serum creatinine concentrations are associated with increased hospital mortality rates. However, whether serum creatinine concentration (SCr) on admission and its change are associated with an increased mortality rate in mechanically ventilated patients is not known. We have conducted an international, prospective, observational cohort study enrolling adult intensive care unit patients under mechanical ventilation (MV). Recursive partitioning was used to determine the values of SCr at the start of MV (SCr0) and the change in SCr ([DeltaSCr] defined as the maximal difference between the value at start of MV [day 0] and the value on MV day 2 at 8:00 am) that best discriminate mortality. In-hospital mortality, adjusted by a proportional hazards model, was the primary outcome variable. A total of 2,807 patients were included; median age was 59 years and median Simplified Acute Physiology Score II was 44. All-cause in-hospital mortality was 44%. The variable that best discriminated outcome was a SCr0 greater than 1.40 mg/dL (mortality, 57% vs. 36% for patients with SCr0

    Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths in China. Evidence has shown that surgical resection and liver transplantation may offer the best potential for treating HCC but are only available to patients whose tumors are detected early. Over the past few decades, although a series of measures for standardized management of HCC has been implemented in China, most patients with HCC in China still present with advanced-stage disease, thus strategies to screen for and diagnose HCC at an earlier stage are urgently needed in China when curable interventions can be offered to achieve long-term disease-free survival for patients with HCC. In China, the serum biomarker α-fetoprotein (AFP) is considered a useful and feasible tool for HCC screening and early diagnosis. However, the sensitivity and specificity of AFP vary widely, and the total AFP is not always specific, especially when HCC is in its early stages. Globally, numerous studies have reported that the combination of des-γ-carboxyprothrombin (DCP) and AFP may have a higher sensitivity than AFP alone, and suggested DCP could also be used to assess the progression of HCC. However, DCP has not been approved in China until now. Differ from most of Western countries, people with HBV infection are the largest population at risk of developing HCC China. In order to assess the screening and diagnostic value of DCP in Chinese patients with HCC, a first large-scale, multi-center study was launched in China in 2012, results showed that DCP can help to detect HCC in its early stages and facilitate definitive treatment. The clinical use of DCP is urgently needed to facilitate early detection of HCC in China.

    Antipsychotic and other medications used in the treatment of schizophrenia place a burden on the cholinergic subsystems of the brain, which have been associated with increased cognitive impairment in the disorder. This study sought to examine the neurobiologic correlates of the association between serum anticholinergic activity (SAA) and cognitive impairments in early schizophrenia. Neurocognitive performance on measures of memory and executive function, structural magnetic resonance imaging (MRI) scans, and SAA assays were collected from 47 early course, stabilized outpatients with schizophrenia or schizoaffective disorder. Voxel-based morphometry analyses employing general linear models, adjusting for demographic and illness-related confounds, were used to investigate the associations between SAA, gray matter morphology, and neurocognitive impairment. SAA was related to working memory and executive function impairments. Higher SAA was significantly associated with lower gray matter density in broad regions of the frontal and medial-temporal lobes, including the dorsolateral prefrontal cortex (DLPFC), hippocampus, and striatum. Lower gray matter volume in the left DLPFC was found to significantly mediate the association between SAA and working memory impairment. Disease and/or medication-related cholinergic dysfunction may be associated with brain volume abnormalities in early course schizophrenia, which may account for the association between SAA and cognitive dysfunction in the disorder.

    Most cases of acute arsenic poisoning occur through accidental or voluntary ingestion of pesticides or insecticides, and all body systems are affected. Arsenic can prolong the QT interval and lead to torsades of Pointes, a crucial type of arrhythmia characteristic of such QT interval prolongation. In our revision of the literature, there have been found only 5 cases of torsades of Pointes due to acute arsenic poisoning. Recently, there have been published four additional cases in patients with refractory or recurrent acute promyelocytic leukemia being treated with arsenic trioxide. In all nine cases, torsades of pointes appeared slowly after poisoning. Herein is described a case of acute arsenic poisoning which led to an early onset of torsades of Pointes, hypopotasemia and high levels of serum troponin I.

    Circulating trimethylamine N-Oxide (TMAO) levels predict cardiovascular disease (CVD), possibly by impacting on cholesterol metabolism and oxidative stress. Because hepatic TMAO production is regulated by insulin signalling and it is unclear whether and to what extent circulating TMAO levels associate with CVD risk, independently of insulin resistance and its important determinants fatty liver and visceral obesity, we have now addressed this question in 220 subjects who participated in the Tübingen Lifestyle Intervention Program. Visceral fat mass (r = 0.40, p < 0.0001), liver fat content (r = 0.23, p = 0.0005) and TMAO levels (r = 0.26, p < 0.0001) associated positively, and insulin sensitivity associated negatively (r = -0.18, p = 0.009) with carotid intima-media thickness (cIMT). Higher TMAO levels (std.-Beta 0.11, p = 0.03) predicted increased cIMT, independently of age, sex and visceral fat mass. While during the lifestyle intervention most cardiovascular risk parameters improved, mean TMAO levels did not change (p = 0.18). However, cIMT decreased significantly (p = 0.0056) only in subjects in the tertile with the largest decrease of TMAO levels (>20%). We provide novel information that increased serum TMAO levels associate with increased cIMT, independently of established cardiovascular risk markers, including insulin resistance, visceral obesity and fatty liver. Furthermore, the decrease of cIMT during a lifestyle intervention may be related to the decrease of TMAO levels.

    Aim. To examine the potential value of previously identified biomarkers using proteomics in early screening for preeclampsia (PE). Methods. 24 blood samples from women who subsequently developed PE and 48 from uncomplicated pregnancies were obtained at 11–13 weeks and analysed after delivery. Cystatin-C, sVCAM-1, and Pappalysin-1 were quantified by ELISA. Maternal characteristics and medical history were recorded. Results. Median values of Cystatin-C, sVCAM-1, and Pappalysin-1 in the PE group as compared to controls were 909.1 gEq/mL versus 480.0 gEq/mL, P = .000, 832.0 gEq/mL versus 738.8 gEq/mL, P = .024, and 234.4 gEq/mL versus 74.9 gEq/mL, P = .064, respectively. Areas under the receiver-operating characteristic curves (AUC, standard error (SE)) for predicting PE were Cystatin-C: 0.90 (SE 0.04), VCAM-1: 0.66 (SE 0.074), and Pappalysin-1: 0.63 (SE 0.083). To discriminate between cases at risk for PE and normal controls, cut-off values of 546.8 gEq/mL for Cystatin-C, 1059.5 gEq/mL for sVCAM-1, and 220.8 gEq/mL for Pappalysin-1 were chosen, providing sensitivity of 91%, 41%, and 54% and specificity of 85%, 100%, and 95%, respectively. Conclusions. sVCAM-1 and Pappalysin-1 do not improve early screening for PE. Cystatin-C, however, seems to be associated with subsequent PE development, but larger studies are necessary to validate these findings. PMID:25628472

    A combined test performed at the 12th week of gestation enables us to classify the pregnancy as high risk (risk higher than 1:300) or low risk (risk lower than 1:300) for congenital foetal anomalies, with great accuracy of 85 - 90%. According to the available data, the frequency of false positive results is estimated at around 5%. The objective of the study was to examine possible correlation between the serum marker values and amniocentesis results in prenatal diagnostics of congenital foetal anomalies. The study included 745 pregnant women monitored by the Genetic Counselling Service of the Clinic of Gynaecology and Obstetrics of the Clinics Centre Kragujevac. The subjects were included in the study under condition that CRL (embryonic crown-rump length) was from 45 to 84 mm and that the gestational age was at 11-13+6 weeks. Free beta HCG and PAPP-A were determined from venous blood using commercial DPS-USA tests. Tests were based on the analytic principle of the immuno-chemiluminescence technique and were performed by application of the automatic Immulite 2000 analyzer by DPC-USA. The foetal nuchal translucency thickness (NT) and CRL were measured by Colour Doppler. The chromosome identification was performed after a certain number of cell divisions by stopping the cell division in metaphase of mitosis when the chromosomes were the most distinguishable. The foetal karyotype was prepared using G bands. In the total sample of pregnant women (n=745), there were six cases of pathological foetal karyotype. A statistical paradox in the frequency of congenital foetal anomalies in favour of younger population was noticed. A high coefficient of Spearman's rank correlation suggests great importance of the combined test in the detection of congenital foetal anomalies (p<0,05). A high consistency was also proved for components of biochemical screening and ultrasonographic markers. The combined test, as a method of prenatal screening in the first trimester of pregnancy, if

    Early prostate cancer antigen (EPCA) has been recently suggested as a novel biomarker in malignant and premalignant lesions of the prostate. This study was to examine serum expression of EPCA and to further clarify the relationship between initial serum EPCA levels and the presence of subsequent cancer in the individuals with isolated high-grade prostatic intraepithelial neoplasia (HGPIN). An indirect ELISA was used for initial serum EPCA measurement in 112 men with isolated HGPIN, who were enrolled and completed a follow-up of >or=5 years. All patients had a detectable concentration of EPCA in the initial serum, with a mean of 0.64+/-0.13 absorbance at 450 nm. Thirty-three patients had an initial serum EPCA level of >or=1.10, in which 31 cases were subsequently identified as having prostate cancer on follow-up. However, in the remaining 79 cases, serum EPCA levels were all <1.10, and none was diagnosed with cancer later. Statistical analysis showed a significantly higher serum ECPA level in isolated HGPIN patients with subsequent cancer than those without cancer (P<0.001). The area under the receiver operating characteristic curves showed that serum EPCA level had better predictive accuracy of cancer onset on follow-up than prostate specific antigen velocity and abnormal digital rectal examination findings. Furthermore, univariate and multivariate Cox regression analyses demonstrated the predictive performance independently by initial serum EPCA>or=1.10 absorbance (relative risk, 3.32; 95% confidence intervals, 2.62-5.03, P<0.001). These preliminary findings first show the potential of serum EPCA to serve as a significant predictor for subsequent cancer in isolated HGPIN.

    Purpose. To compare the 2-year effect of multiple doses of lutein/zeaxanthin on serum, macular pigmentation, and visual performance on patients with early age-related macular degeneration (AMD). Methods. In this randomized, double-blinded, and placebo-controlled trial, 112 early AMD patients randomly received either 10 mg lutein, 20 mg lutein, a combination of lutein (10 mg) and zeaxanthin (10 mg), or placebo daily for 2 years. Serum concentration of lutein/zeaxanthin, macular pigment optical density (MPOD), visual functions including best-spectacle corrected visual acuity (BCVA), contrast sensitivity (CS), flash recovery time (FRT), and vision-related quality of life (VFQ25) was quantified. Results. Serum lutein concentration and MPOD significantly increased in all the active treatment groups. Supplementation with 20 mg lutein was the most effective in increasing MPOD and CS at 3 cycles/degree for the first 48 weeks. However, they both significantly increased to the same peak value following supplementation with either 10 mg or 20 mg lutein during the intervention. No statistical changes of BCVA or FRT were observed during the trial. Conclusions. Long-term lutein supplementation could increase serum lutein concentration, MPOD, and visual sensitivities of early AMD patients. 10 mg lutein daily might be an advisable long-term dosage for early AMD treatment.

    This study was aimed at determining the effect of oral administration of warm water during the postoperative initial stage on the time of first flatus in patients who had undergone laparoscopic cholecystectomy. In the literature, it is emphasized that warm water has favorable effects on intestinal movements such as "reliving gastrointestinal spasms and helping peristalsis return." This randomized controlled trial and experimental study was conducted in a university hospital between May and December 2011. In the study sample, we included a total of 60 patients; 30 were in the experimental group (drank warm water), while the other 30 composed the control group. Patients were randomized through a simple random sampling method. The experimental group was provided with 200 ml of warm water at 98.6°F (37°C) in the fourth postoperative hour and were made to drink it within 15 minutes. Patients received no oral intake other than warm water until the eighth postoperative hour. The oral feeding of both groups started in the eighth postoperative hour with fluids and soft food. They shifted to the normal diet as tolerated. In the analysis of the data and percentage numbers, chi-square test and Fisher's exact test, Student's t test, Mann-Whitney U test, Kruskal-Wallis variance, and correlation analysis were used. The results of the data were considered reliable and statistically significant when they were in the reliability interval of 95% and p < .05. No significant differences were found between the patients in the experimental and control groups in terms of demographic features, bowel habits, surgery durations, postoperative applications, nausea/vomiting conditions, and initial mobilization times (p > .05). Groups were homogeneously distributed. Flatus expulsion in the experimental group was 11 ± 4.2 hours and was determined to be 18.6 ± 6 hours for patients in the control group (p < .05); in contrast, no significant difference was detected in terms of the times of stool

    The study was designed to test whether circulating autoantibodies against associated antigens (TAAs) were altered in early cervical cancer and benign cervical tumors. A total of 111 cervical cancer patients, 137 cervical benign tumor patients, and 160 healthy volunteers matched in age were recruited in this study. The expression of autoantibodies was tested using in-house developed enzyme-linked immunosorbent assay (ELISA) with linear peptide envelope antigens derived from TAAs. One-way ANOVA test showed that there was no difference in the CD25 autoantibody expression among the cervical cancer group, benign tumor group, and healthy control group (P = 0.063; P = 0.191). The expression of autoantibodies against survivin and TP53 in the cervical cancer group was significantly higher than that in the benign tumor group (P < 0.001; P < 0.001). The levels of autoantibodies against cyclinB-1 and ANXA-1 were higher in the cervical cancer group than in the healthy control group (P = 0.010; P = 0.001), while autoantibodies in the cervical cancer group showed no difference in expression compared with that in the benign tumor group. The panel of five TAAs showed a sensitivity of 37.8 % and a specificity of 90 %, which was much higher than the sensitivity of the single-TAA testing group. The data from this study further support our previous hypothesis that the detection of autoantibodies for the diagnosis of a specific cancer type can be enhanced using a panel of several selected TAAs as target antigens.

    The knee range of motion is an important outcome of total knee arthroplasty (TKA). According to previous studies, the knee range of motion temporarily decreases for approximately 1 month after TKA due to postoperative pain and quadriceps dysfunction following surgical invasion into the knee extensor mechanism. We describe our experience with a knee-extension training program based on a single-joint hybrid assistive limb (HAL-SJ, Cyberdyne Inc., Tsukuba, Japan) during the acute recovery phase after TKA. HAL-SJ is a wearable robot suit that facilitates the voluntary control of knee joint motion. A 76-year-old man underwent HAL-SJ-based knee-extension training, which enabled him to perform knee function training during the acute phase after TKA without causing increased pain. Thus, he regained the ability to fully extend his knee postoperatively. HAL-SJ-based knee-extension training can be used as a novel post-TKA rehabilitation modality. PMID:27774330

    Previous studies done in animals have shown that significant prophylaxis against radiation injury could be afforded by feeding an elemental diet (ED) for three days before and during radiation. In the present study 20 patients were fed an ED for three days before and for the four days during radiotherapy (five fractions of 400 rad (4 Gy) each) prior to radical cystectomy and ileal conduit for invasive bladder cancer; ED feeding was recommenced 24 hours postoperatively via a feeding jejunostomy. The ED-fed patients exhibited positive nitrogen balance preoperatively and had an early return to positive nitrogen balance postoperatively (3.60 +/- 0.32 days). There was also prompt return of bowel sounds (3.00 +/- 0.32 days). Histologically and ultrastructurally, biopsy specimens of the ileal mucosa showed normal morphologic findings, with maintenance of normal levels of enzyme activity in the brush border. Severe or bloody diarrhea was absent in these patients. These data suggest that ED feeding provides prophylaxis against the acute phase of radiation injury in patients undergoing high-dose, short-course radiotherapy for invasive bladder cancer and that it is a safe and feasible means of postoperative nutritional support, even in the presence of a fresh bowel anastomosis.

    OBJECTIVES The mechanism of action of methotrexate in rheumatoid arthritis (RA) is complex. It may increase adenosine levels by blocking its conversion to uric acid (UA). This study was done to determine if methotrexate lowers UA in early RA (ERA). METHODS Data were obtained from Canadian Early Arthritis Cohort, an incident ERA cohort. All ERA patients with serial UA measurements were included, comparing those with methotrexate use vs. no methotrexate exposure (controls). Analyses were exploratory. Patients with concomitant gout or taking UA-lowering therapies were excluded. RESULTS In total, 49 of the 2,524 ERA patients were identified with data available for both pre-methotrexate UA levels and post-methotrexate UA levels (300 µmol/L and 273 µmol/L, respectively; P = 0.035). The control group not taking methotrexate had a mean baseline UA level of 280 µmol/L and a follow-up level of 282 µmol/L (P = 0.448); mean change in UA with methotrexate was −26.8 µmol/L vs. 2.3 µmol/L in the no methotrexate group (P = 0.042). Methotrexate users with a decrease in UA had a disease activity score of 2.37 for 28 joints when compared with the controls (3.26) at 18 months (P = 0.042). Methotrexate users with decreased UA had a lower swollen joint count (SJC) of 0.9 at 18 months, whereas methotrexate users without lowering of UA had an SJC of 4.5 (P = 0.035). Other analyses were not significant. CONCLUSIONS Methotrexate response is associated with lowering of serum UA in ERA compared to nonusers. This may be due to changes in adenosine levels. Methotrexate response is associated with lower UA and fewer swollen joints compared to nonresponders. PMID:27081318

    Epidural analgesia with local anesthetics and opioids is one of the most effective methods for postoperative pain control. In critical patients it seems to improve outcome as well as pain control. This technique works better when started in the intraoperative time. Epidural analgesia is safe on surgical wards if nursing staff is trained in managing epidural catheters and in early detection and treatment of major and minor side effects. Nursing staff cooperates with the Acute Pain Service doctors and nurses who are on call on a 24 hour basis. Many perspective and retrospective studies showed a very low incidence of major side effects with epidurals. So we can consider it safe and effective even if we consider its invasiveness.

    Simple and accurate diagnosis of vertical transmission of human parvovirus B19 (B19V) infection remains an important issue in pregnancy. There are few reports on quantitative analysis of B19V in amniotic fluids. Quantitative estimation of B19V DNA in amniotic fluids was comparerd with those in maternal or fetal serum obtained at an early stage of pregnancy with possible mother-to-fetus transmission. All pregnant women contracted B19V infection between 13 to 14 weeks gestation. The B19V DNA amount in 3 maternal serum and amniotic fluid sample pairs collected between 16 to 27 weeks gestation was quantified by a real-time polymerase chain reaction assay. Serum from 2 fetuses was included. The B19V DNA concentrations in maternal sera and amniotic fluids ranged from 10(4) to 10(5) copies/ml and from 10(7) to 10(8) copies/ml, respectively. The B19V DNA in the amniotic fluids concentration coincided with those of each fetal serum. The concentrations in amniotic fluids are 100 to 5,000 times higher than in those of maternal sera, and corresponded to the matching fetal serum. Amniotic fluids may substitute for the fetal sera in terms of quantitative estimation of fetal B19V infection at an early stage of pregnancy.

    Blood transcriptome reflects the status of diseases, and characteristic molecular signature provides a novel window on gene expression preceding acute coronary events. We aim to determine blood transcriptome-based molecular signature of acute coronary syndrome (ACS), and to identify novel serum biomarkers for early stage ST-segment-elevation myocardial infarction (STEMI). We obtained peripheral blood from the patients with ACS who visited emergency department within 4 hours after the onset of chest pain: STEMI (n = 10), Non-ST-segment-elevation MI (NSTEMI, n = 10) and unstable angina (UA, n = 11). Blood transcriptome scans revealed that a characteristic gene expression change exists in STEMI, resulting in 531 outlier genes as STEMI molecular signature (Welch's t test, P < 0.05). Another analysis with a set of blood samples of patients with STEMI (n = 7) before and 7 days after the primary percutaneous coronary intervention (n = 7) and normal control (n = 10) evidenced that STEMI molecular signature directly reflects the onset of STEMI pathogenesis. From the two sets of transcriptome-based STEMI signatures, we identified 10 genes encoding transmembrane or secretory proteins that are highly expressed in STEMI. We validated blood protein expression levels of these 10 putative biomarkers in 40 STEMI and 32 healthy subjects by ELISA. Data suggested that PGLYRP1, IRAK3 and VNN3 are more specific and sensitive diagnostic biomarkers for STEMI than traditional CK-MB or troponin. Blood transcriptome scans of ACS evidenced early stage molecular markers for STEMI. Here, we report novel biomarkers to diagnose STEMI at emergency department in hospitals by a simple ELISA method.

    Renal cell carcinoma (RCC) is frequently diagnosed at advanced stages of disease, although early diagnosis has much favorable prognosis. This study assessed aberrant expression of cytosolic carboxypeptidase 6 (CCP6) leading to accumulation of serum polyglutamylated DNAJC7 as a biomarker for early RCC detection. A total of 835 RCCs, 143 chronic nephritis, 170 kidney stones and 415 health controls were collected for qRT-PCR, immunohistochemistry and Western blot analysis of CCP6 expression and mass spectrometry of DNAJC7 and polyglutamylated DNAJC7. The data showed that CCP6 expression was significantly decreased in 30 RCC tissues and that mass spectrometric and pull-down analysis identified DNAJC7 as a substrate of CCP6 and showed upregulated polyglutamylated-DNAJC7 (polyE-DNAJC7) in sera of RCC patients. The electrochemiluminescence immunoassay of large-scale serum samples from multi-institutes further confirmed the remarkable increase of polyE-DNAJC7 in 805 RCCs compared to that of 385 healthy controls (p < 0.001), 128 patients with chronic nephritis (p < 0.001), and 153 with kidney stone (p < 0.001). Serum level of DNAJC7-polyE protein was also associated with advanced RCC stage and grade in 805 patients. The data from the current study for the first time demonstrated increased serum polyglutamylated DNAJC7 as a potential biomarker for RCC early detection and association with advanced tumor stages and grade, which provides support of further polyglutamylation research in RCC.

    Objectif : Comparer, chez des femmes devant subir une chirurgie gynécologique majeure, les effets de la reprise postopératoire précoce ou différée de l’alimentation en ce qui a trait aux résultats cliniques, à la durée de l’hospitalisation postopératoire et à la satisfaction de la patiente. Méthodes : Nous avons mené un essai comparatif randomisé parallèle dans un centre de soins tertiaires de Montréal, au Québec, entre juin 2000 et juillet 2001. Les patientes devant subir une chirurgie gynécologique majeure ont été affectées au hasard (selon un ratio d’attribution 1:1) à un groupe devant connaître une reprise postopératoire de l’alimentation précoce (dans le cadre de laquelle l’administration de liquides clairs par voie orale a été entamée dans les six heures suivant la tenue de la chirurgie, suivie de celle d’aliments solides, en fonction de la tolérance) ou différée (dans le cadre de laquelle l’administration de liquides clairs a été entamée au cours de la première journée postopératoire et celle d’aliments solides, au cours de la deuxième ou de la troisième journée postopératoire, en fonction de la tolérance). Les principaux critères d’évaluation analysés ont été la durée de l’hospitalisation postopératoire et la satisfaction de la patiente. Parmi les critères d’évaluation secondaires, on trouvait le délai moyen avant le retour de l’appétit, de l’expulsion de flatuosités et de la défécation, ainsi que la présence de symptômes d’iléus paralytique. Résultats : Au total, nous avons recruté 119 patientes : 61 patientes ont été affectées au hasard au groupe « alimentation précoce » et 58, au groupe « alimentation différée ». Toutes les participantes comptaient des caractéristiques démographiques (dont l’âge, le poids, le statut quant au tabagisme et les antécédents chirurgicaux) comparables.

    Objective: To determine whether or not the level of serum anti-Müllerian hormone (AMH) is related to early ovarian aging in young women (< 35 years of age) undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles. Design: Retrospective cohort study. Setting: An IVF laboratory in a university hospital in Taiwan. Patient (s): 70 young women (< 35 years of age) with low level of serum AMH (< 2 ng/ml) and 104 young women with level of serum AMH (≥ 2 ng/ml) who underwent IVF/ICSI cycles between January 2011 and November 2012 were enrolled. Intervention (s): None. Main outcome measure (s): Number of oocytes, fertilization rate, embryo quality, cycle cancellation rate, clinical pregnancy/abortion rate, and perinatal/infant outcomes. Results: The clinical pregnancy rate per transfer was favorable (low AMH group vs. normal AMH group [47.2% and 47.9%]) for women < 35 years of age, including women with a low serum AMH. Similarly, the live birth rate per transfer (low AMH group vs. normal AMH group [37.7% and 35.4%]) and perinatal outcomes were also comparable between the two groups. A significantly higher cycle cancellation was noted in the low AMH group than the normal AMH group (24.2% vs. 7.6%). Conclusion: Although early ovarian aging should be taken into consideration for young and infertile women with low AMH level than expected, our results suggest that low serum AMH level may suggest early ovarian aging in accelerated oocyte loss only, but may not fully represent “early ovarian aging” based on the favorable outcomes of pregnancy.

    To determine the relationship between resistive index (RI) measured by Doppler ultrasound, serum creatinine (SCr), and histopathological changes on biopsy during kidney trans- plant dysfunction in early postoperative period, we studied 47 kidney transplant patients; 61% of the patients had acute transplant rejection, 19% had acute tubular necrosis, 4% had calcineurin inhibitor toxicity, 11% had normal morphology in biopsy, and 5% had changes compatible with pyelonephritis. None of the study patients had interstitial fibrosis or tubular atrophy on biopsy. We found that the sensitivity and specificity of RI in diagnosing transplant dysfunction was highly variable depending on the selected cutoff value. Sensitivity of RI decreased and its specificity increased with increasing the RI thresholds. Using an RI threshold of 0.7 resulted in a high sensitivity of 78% at a cost of very low specificity 40%, whereas using an RI threshold of 0.9 resulted in 100% specificity at a cost of very low sensitivity 16%. Acceptable specificity was only achieved at the expense of very low sensitivity, resulting in poor utility of RI as a screening tool for dysfunction. We found that there were no significant differences in the mean RI value between patients with and without biopsy-proven transplant dysfunction. However, we found a significant correlation between SCr value and RI of 0.383, P = 0.007.

    In clinical practice, there is still a need for novel biomarkers, which can reliably rule in or rule out acute coronary syndrome (ACS) immediately on admission. This is of particular interest in patients with unstable angina (UA) and non-ST-segment elevation myocardial infarction (NSTEMI) in whom diagnostic uncertainty is high. The aim of the present study is to evaluate the potential role of miRNA-499 and miRNA-210 as novel molecular biomarkers for early diagnosis of UA and NSTEMI suspected patients presented at the emergency unit. A total of 110 patients presenting to the intensive care unit (ICU) within 24 h of onset of chest pain suggestive of ACS were enrolled in the study. They included 37 UA, 48 NSTEMI and 25 noncardiac chest pain (NCCP) patients. Immediately at enrollment, blood samples were taken for estimation of serum miRNA-499 and miRNA-210 expression levels by real time PCR. miRNA-499 and miRNA-210 expression levels were significantly increased in UA and NSTEMI patients compared with NCCP patients (P < 0.001). Receiver operating characteristic (ROC) curve analysis revealed that the area under curve (AUC) of miR-499 for the diagnosis of UA and NSTEMI was 0.98 and 0.97, respectively; while the AUC of miRNA-210 was 0.84 and 0.90, respectively. The important finding of our study was that the AUC of miRNA-499 for the diagnosis of ACS patients with symptoms onset <3 h was 0.89, while the AUC of miRNA-210 was 0.86. Interestingly, combining miRNA-499 and miRNA-210 significantly improved the diagnostic value by increasing the AUC to 0.96, P < 0.001. In conclusion, serum miRNA-499 and miRNA-210 are associated with UA and NSTEMI and with those presenting within 3 h of symptom onset. Both miRNAs might be potentially novel biomarkers for accelerating the diagnosis of ACS patients in emergency unit. © 2016 IUBMB Life, 68(8):673-682, 2016. PMID:27346801

    Purpose Circulating microRNAs (miRNAs) are emerging as promising diagnostic biomarkers for colorectal cancer (CRC), but their usefulness for detecting early colorectal neoplasms (CRNs) remains unclear. This study aimed to identify serum miRNA biomarkers for the identification of patients with early CRNs. Experimental Design A cohort of 237 serum samples from 160 patients with early CRNs (148 precancerous lesions and 12 cancers) and 77 healthy subjects was analyzed in a three-step approach that included: a comprehensive literature review for published biomarkers, a screening phase, and a validation phase. RNA was extracted from sera, and levels of miRNAs were examined by real-time RT-PCR. Results Nine miRNAs (miR-18a, miR-19a, miR-19b, miR-20a, miR-21, miR-24, miR-29a, miR-92 and miR-125b) were selected as candidate biomarkers for initial analysis. In the screening phase, serum levels of miR-21, miR-29a and miR-125b were significantly higher in patients with early CRN compared to healthy controls. Elevated levels of miR-21, miR-29a and miR-125b were confirmed in the validation phase using an independent set of subjects. Area under the curve (AUC) values for serum miR-21, miR-29a, miR-125b, and their combined score in discriminating early CRN patients from healthy controls were 0.706, 0.741, 0.806 and 0.827 respectively. Serum levels of miR-29a and miR-125b were significantly higher in patients who only had small CRNs (≤5mm) compared to healthy subjects. Conclusions Since serum levels of miR-21, miR-29a and miR-125b discriminated early CRN patients from healthy controls, our data highlight the potential clinical use of these molecular signatures for noninvasive screening of patients with colorectal neoplasia.

    Background The occurrence and severity of corneal oedema after phacoemulsification is dependent on the integrity of corneal endothelial cells. The function of these cells is affected by diabetes mellitus and consequently the behaviour of the cornea in diabetic patients is of special interest. Aim To compare the frequency of corneal oedema in two age-matched groups of diabetics and non diabetic patients that underwent cataract surgery in the Ophthalmology Department of Xanthi General Hospital in Greece. Methods A retrospective case control study was conducted in a retrospective fashion. Patients in the control and study groups were assessed regarding the severity of corneal oedema at three postoperative visits: days 1, 3–7, 10–14 after the operation. Ultrasound energy consumed during phacoemulsification was also a parameter of interest and possible correlations with the pre-existent cataract severity and the subsequent incidence of corneal oedema were investigated. Results The difference in the incidence of severe corneal oedema between the study and control group was statistically significant: (4.5% non diabetics vs 14.3% diabetics). The consumed ultrasound energy did not define final clinical outcome. Conclusions The existence of diabetes mellitus type 2 appears to be a significant risk factor for the development of persistent corneal oedema. The results of our study led to the modification of the algorithm for postoperative follow-up of patients of this remote area of Greece. PMID:26865977

    In conclusion, delirium is a common postoperative complication that especially impacts the elderly population. It contributes to a significant increase in morbidity, mortality, length of inpatient stay, and medical costs. Even with preventive efforts, many patients will develop postoperative delirium. While the gold standard treatment is to correct the underlying disorder, many therapies ranging from the use of antipsychotics to patient comfort measures are used to decrease the severity and duration of postoperative delirium. The most practical approach for physicians is continuous vigilance for the emergence of postoperative delirium. Movement toward increased use of multidisciplinary inpatient ward teams, early psychiatric consultation during postoperative delirium, larger clinical trials of prophylactic medications, and future research on delirium's pathogenesis will decrease complications of this common clinical problem.

    Pancreatic cancer is a highly malignant disease with a poor prognosis and it is essential to diagnose and treat the disease at an early stage. The aim of this study was to understand the underlying biochemical mechanisms of pancreatic intraepithelial neoplasia (PanIN) and pancreatic ductal adenocarcinoma (PDAC) and to identify potential serum biomarkers for early detection of pancreatic cancer. 7,12-Dimethylbenz(a)anthracene (DMBA)-induced PanIN and PDAC rat models were established and the serum samples were collected. The serum samples were measured using (1)H nuclear magnetic resonance (NMR) spectroscopy and analyzed by chemometric methods including principal component analysis (PCA) and (orthogonal) partial least squares discriminant analysis ((O)PLS-DA). The related biochemical pathways were derived from KEGG analysis of the significantly different metabolites. As results, some serum metabolites demonstrated alarming metabolic changes in the precursor lesion of pancreatic cancer (PanIN-2 in this study). These changes involved elevated levels of ketone compounds including 3-hydroxybutyrate, acetoacetate, and acetone, some amino acids including asparagine, glutamate, threonine, and phenylalanine, glycoproteins and lipoproteins including N-acetylglycoprotein, LDL and VLDL, and some metabolites that have been shown to contribute to mutagenicity and cancer promotion such as deoxyguanosine and cytidine. More metabolites were shown to be significantly different between PanIN and PDAC, suggesting that a more complex set of changes occurs from noninvasive precursor lesion to invasive cancer. The serum metabonomic changes of rats with PanIN and PDAC may extend our understanding of pancreatic molecular pathogenesis, and the metabolic variations from PanIN to PDAC will be helpful to understand evolution processes of the pancreatic disease. NMR-based metabonomic analysis of animal models will be beneficial for the human study and will be helpful for the early detection of

    Introduction The presentation of Ectopic Pregnancy (EP) can be highly variable and serum Beta hCG estimation plays an important role in early diagnosis. Aim Aim of the study was to determine the trends of hCG levels in EP and to explore the role of hCG in decisions related to management and follow-up of EPs. Materials and Methods A retrospective study of women who had EPs from January 2006 to December 2012 at an advanced tertiary care centre in southern India was carried out. These women had undergone treatment based on the hospital protocol. Results The study identified 337 women with EP. Thirty one surgically confirmed cases were diagnosed below the discriminatory zone of 1500 mIU/ml. Among women who had Beta hCG estimations 48 hours apart, plateauing was observed in 22.5% while decrease >15% was noted in 26.8%. Almost half (47.9%) of the cases had an increase >15% and a few (2.8%) demonstrated an initial fall followed by a rise in titres. In 23.9% of these women, there was a rise >53% similar to intrauterine pregnancy. The average pre-treatment Beta hCG was 429.8, 3866.2 and 12961.5 mIU/ml for those who received expectant, medical and direct surgical treatment respectively. 43 women with relative contraindications received medical management and 39 were lost to follow-up after medical and expectant management. Excluding them, the success rate of these two modalities was 76.6% and 85.0% respectively. Conclusion No single level of Beta hCG is diagnostic of EP and serial levels can demonstrate atypical trends in some cases. Hence, interpretation of these results should be done in conjunction with clinical and sonographic findings to arrive at a correct diagnosis. PMID:27630909

    Various attempts were made to improve the diagnosis of the periparturient hypogalactia syndrome in sows. A new approach was the detection of elevated concentrations of acute phase proteins. The objective of our study was to investigate the serum concentrations of haptoglobin (Hp) and C-reactive protein (CRP) in sows on Day 7 postpartum and relationship to body temperature. From Day 1 to Day 6 postpartum, 199 sows were clinically examined and a blood sample was taken for measuring Hp and CRP at Day 7. The median of Hp and CRP were 1.83 mg/mL (interquartile range: 1.42-2.13 mg/mL) and 60.0 μg/mL (interquartile range: 15.2-216.5 μg/mL). We did not find a correlation between Hp and CRP (ρ = 0.11, P = 0.12) nor a difference between sows categorized as ill and healthy sows in Hp concentration (P = 0.1) and CRP (P = 0.34). Sows with Hp > 2.13 mg/mL had a higher rectal temperature than sows with Hp ≤ 2.13 mg/mL (P = 0.037), but there was no difference in vaginal temperature (P = 0.24). Regarding CRP, sows with CRP greater than 216.5 μg/mL had higher rectal temperature (P = 0.017) and vaginal temperature (P = 0.02) than sows with CRP ≤ 216.5 μg/mL. As demonstrated in this study, Hp and CRP do not support the detection of early postpartum disorders in sows.

    Background Ischemia Modified Albumin (IMA) is an altered serum albumin that forms under the conditions of oxidative stress and is considered as a biomarker of cardiac ischemia. The objective of this study was to evaluate the ischemia modified albumin (IMA) in the serum of the individuals with different types of tobacco habits in order to investigate the possibility of using this as a biomarker for the oxidative stress induced by the tobacco products. Materials and Methods The study included 90 subjects, who were Grouped as control (30), Group I (betel quid chewers), Group II (gutkha chewers), Group III (smokers) and Group IV (mixed). Serum was collected from subjects of all Groups and IMA estimation was done using Albumin Cobalt binding assay. The results were tabulated and analysed statistically. Results The mean serum IMA levels in control, Group I, Group II, Group III and Group IV were 0.52547 ABSU, 0.68767 ABSU, 0.47433 ABSU,0.36540 ABSU and 0.54593 ABSU respectively. Conclusion The results show that serum IMA levels were increased in betel quid chewers and mixed Group compared to the controls. From the results noted in this study we suggest that IMA can be used as an early marker for tobacco related oxidative stress. PMID:26674345

    Objectives 1) To explore the adequacy of: vital signs’ recordings (respiratory and heart rate, oxygen saturation, systolic blood pressure (BP), temperature, level of consciousness and urine output) in the first 8 post-operative hours; responses to clinical deterioration. 2) To identify factors associated with death on the ward between transfer from the theatre recovery suite and the seventh day after operation. Design Retrospective review of records of 11 patients who died plus four controls for each case. Participants We reviewed clinical records of 55 patients who met inclusion criteria (general anaesthetic, age >13, complete records) from six surgical wards in a teaching hospital between 1 May and 31 July 2009. Methods In the absence of guidelines for routine post-operative vital signs’ monitoring, nurses’ standard practice graphical plots of recordings were recoded into MEWS formats (0 = normal, 1–3 upper or lower limit) and their responses to clinical deterioration were interpreted using MEWS reporting algorithms. Results No patients’ records contained recordings for all seven parameters displayed on the MEWS. There was no evidence of response to: 22/36 (61.1%) abnormal vital signs for patients who died that would have triggered an escalated MEWS reporting algorithm; 81/87 (93.1%) for controls. Death was associated with age, ≥61 years (OR 14.2, 3.0–68.0); ≥2 pre-existing co-morbidities (OR 75.3, 3.7–1527.4); high/low systolic BP on admission (OR 7.2, 1.5–34.2); tachycardia (≥111–129 bpm) (OR 6.6, 1.4–30.0) and low systolic BP (≤81–100 mmHg), as defined by the MEWS (OR 8.0, 1.9–33.1). Conclusions Guidelines for post-operative vital signs’ monitoring and reporting need to be established. The MEWS provides a useful scoring system for interpreting clinical deterioration and guiding intervention.

    The incidence of postoperative spinal infections increases with the complexity of the procedure. Diskectomy is associated with less than a 1% risk of infection; spinal fusion without instrumentation is associated with a 1%-5% risk; and fusion with instrumentation may be associated with a risk of 6% or more. Twenty-two postoperative posterior spinal infections that occurred during a three-year period were reviewed for this report. Staphylococcus aureus was the most frequent organism cultured (more than 50% of the cases). Other recurring organisms were Staphylococcus epidermis, Peptococcus, Enterobacter cloacae, and Bacteroides. Many patients had multiple organisms. Risk factors appeared to include advanced age, prolonged hospital bed rest, obesity, diabetes, immunosuppression, and infection at remote sites. Operative factors included prolonged surgery (greater than five hours), high volume of personnel moving through the operating room, and instrumentation. Postoperative contamination may occur and may be related to prolonged postoperative bed rest, skin maceration (thoracolumbosacral orthoses), and drainage tubes exiting distally from lumbar wounds (toward the rectum). Effective treatment includes early diagnosis, surgical debridement and irrigation, and parenteral antibiotics. Superficial infections were treated successfully with wound closure over outflow tubes, and deep infections with inflow-outflow systems. Maintaining the instrumentation in place was possible in most cases. Parenteral antibiotics were maintained for six weeks in every case. PMID:1395319

    Laparoscopic sleeve gastrectomy (LSG) effectively reduces weight by restricting gastric capacity and altering gut hormones levels. We designed a prospective study to investigate the correlation of serum uric acid (SUA) concentration and weight loss. SUA and body mass index (BMI) were measured preoperatively and on first postoperative month and year in patients who underwent LSG in our department of bariatric surgery. Data on 55 patients were analyzed. Preoperative SUA concentration had a significant positive correlation with percentage of total weight loss (TWL) on first postoperative month (P = 0.001) and year (P = 0.002). SUA concentration on first postoperative month had a positive correlation with percentage of TWL on first postoperative year (P = 0.004). SUA concentration could be used as a predictor of LSG's success and could help in early detection of patients with rapid loss of weight, in order to prevent complications. PMID:25594659

    Purpose This study evaluated the functional and oncological outcomes of proximal gastrectomy (PG) in comparison with total gastrectomy (TG) for upper-third early gastric cancer (EGC). Materials and Methods The medical records of upper-third EGC patients who had undergone PG (n=192) or TG (n=157) were reviewed. The PG group was further subdivided into patients who had undergone conventional open PG (cPG; n=157) or modified laparoscopy-assisted PG (mLAPG; n=35). Patients who had undergone mLAPG had a longer portion of their intra-abdominal esophagus preserved than patients who had undergone cPG. Surgical morbidity, recurrence, long-term nutritional status, and the incidence of reflux esophagitis were compared between the groups. Results The rate of postoperative complications was significantly lower for PG than TG (16.7% vs. 31.2%), but the five-year overall survival rate was comparable between the two groups (99.3% vs. 96.3%). Postoperative levels of hemoglobin and albumin were significantly higher for patients who had undergone PG. However, the incidence of reflux esophagitis was higher for PG than for TG (37.4% vs. 3.7%; P<0.001). mLAPG was related to a lower incidence of reflux esophagitis after PG (P<0.001). Conclusions Compared to TG, PG showed an advantage in terms of postoperative morbidity and nutrition, and there was a comparable prognosis between the two procedures. Preserving the intra-abdominal esophagus may lower the incidence of reflux esophagitis associated with PG. PMID:26468417

    In this study, we investigated whether the concentrations of pregnancy-associated plasma protein-A (PAPP-A) or free β-hCG (fβhCG) in the first trimester can identify women at increased risk of subsequent preterm delivery in the absence of hypertensive disorders. Preterm and early preterm deliveries are defined as those deliveries before completing 37 and 34 weeks, respectively. A total of 868 women were enrolled into this study. According to the level of the markers, the patients were evaluated in three groups: 1 - maternal serum level ≤ 5 th percentile, 2 - between 5th and 95th percentiles, 3 - ≥ 95 th percentile. In the group of patients with a PAPP-A level ≤ 5 th percentile [≤ 0.35 multiples of the median (MoM)], mean gestational age (GA) at delivery, mean birth weight and the number of the cases with early preterm delivery were significantly lower than the others. Mean level of PAPP-A was significantly lower in cases with early preterm than term deliveries (0.58 ± 0.32 versus 1.09 ± 0.69; p = 0.01). Maternal serum level of fβhCG did not show significant difference between these groups (0.84 ± 0.45 versus 1.17 ± 0.77; p = 0.15). Low levels of maternal serum PAPP-A (≤ 0.35 MoM) (Odds ratio = 7; 95% confidence interval 1.8-27.7; p = 0.0048) significantly predicted early preterm delivery in normotensive pregnancies. Women with low levels of PAPP-A at first trimester have a higher risk of early preterm delivery even in the absence of hypertensive disorders.

    2015-04-01

    Prevention and control of postoperative pain are essential. Inadequate treatment of postoperative pain continues to be a major problem after many surgeries and leads to worse outcomes, including chronic postsurgical pain. Optimal management of postoperative pain requires an understanding of the pathophysiology of pain, methods available to reduce pain, invasiveness of the procedure, and patient factors associated with increased pain, such as anxiety, depression, catastrophizing, and neuroticism. Use of a procedure-specific, multimodal perioperative pain management provides a rational basis for enhanced postoperative pain control, optimization of analgesia, decrease in adverse effects, and improved patient satisfaction.

    Circulating microRNAs are deregulated in liver fibrosis and hepatocellular carcinoma (HCC) and are candidate biomarkers. This study investigated the potential of serum microRNAs; miR-19a, miR-296, miR-130a, miR-195, miR-192, miR-34a, and miR-146a as early diagnostic biomarkers for hepatitis C virus (HCV)-related HCC. As how these microRNAs change during liver fibrosis progression is not clear, we explored their serum levels during fibrosis progression in HCV-associated chronic liver disease (CLD) and if they could serve as non-invasive biomarkers for fibrosis progression to HCC. 112 Egyptian HCV-HCC patients, 125 non-malignant HCV-CLD patients, and 42 healthy controls were included. CLD patients were subdivided according to Metavir fibrosis-scoring. Serum microRNAs were measured by qRT-PCR custom array. Serum microRNAs were deregulated in HCC versus controls, and except miR-130a, they were differentially expressed between HCC and CLD or late fibrosis (F3-F4) subgroup. Serum microRNAs were not significantly different between individual fibrosis-stages or between F1-F2 (early/moderate fibrosis) and F3-F4. Only miR-19a was significantly downregulated from liver fibrosis (F1-F3) to cirrhosis (F4) to HCC. Individual microRNAs discriminated HCC from controls, and except miR-130a, they distinguished HCC from CLD or F3-F4 patients by receiver-operating-characteristic analysis. Multivariate logistic analysis revealed a panel of four microRNAs (miR-19a, miR-195, miR-192, and miR-146a) with high diagnostic accuracy for HCC (AUC = 0.946). The microRNA panel also discriminated HCC from controls (AUC = 0.949), CLD (AUC = 0.945), and F3-F4 (AUC = 0.955). Studied microRNAs were positively correlated in HCC group. miR-19a and miR-34a were correlated with portal vein thrombosis and HCC staging scores, respectively. In conclusion, studied microRNAs, but not miR-130a, could serve as potential early biomarkers for HCC in high-risk groups, with miR-19a as a biomarker for liver fibrosis

    Systemic lupus erythematosus (SLE) is a common but severe autoimmune systemic inflammatory disease. Lupus nephritis (LN) is a serious complication of SLE,affecting up to 70% of SLE patients. Circulating microRNAs (miRNA) are emerging as biomarkers for pathological conditions and play significant roles in intercellular communication. In present research, serum samples from healthy control, early and late stage LN patients were used to analyze the expression profile of miRNAs by microarray. Subsequent study demonstrated that miR-130b-3p in serum of patients with early stage LN were significantly up-regulated when compared with healthy controls. In addition,we have also observed that the expression of a large amount of circulating microRNAs significantly decreased in patients with late stage LN. The further analysis found that the expression of serum miR-130b-3p was positively correlated with 24-hour proteinuria and renal chronicity index in patients with early stage LN.Transfection of renal tubular cellline(HK-2)with miR-130b-3p mimics can promote epithelial-mesenchymal transition (EMT). The opposite effects were observed when transfected with miR-130b-3p inhibitors. MiR-130b-3p negatively regulated ERBB2IP expression by directly targeting the 3‧-UTR of ERBB2IP The circulating miR-130b-3p might serve as a biomarker and play an important role in renal damage in early stage LN patients.

    Maternal serum high-sensitivity C-reactive protein (HSCRP) was evaluated in predicting spontaneous abortion in spontaneous pregnancies presenting with threatened spontaneous abortion. Seventy-one cases of threatened spontaneous abortion (group A) and 71 asymptomatic controls (group B), matched for gestational and maternal age, body mass index and smoking status, were included. Maternal serum samples were evaluated for HCG, progesterone, pregnancy-associated plasma protein-A (PAPP-A) and HSCRP using standard bio-assays. No difference was observed in ultrasound measurements, and median progesterone maternal serum level was significantly lower (P < 0.05) in group A compared with group B. In group A, the median of all ultrasound and maternal serum parameters was significantly lower (P < 0.01) compared with group B. The median gestational sac diameter, volume and median HSCRP and PAPP-A levels were significantly increased (P < 0.05) in group A, with a normal outcome compared with group B, probably owing to the inflammatory reaction associated with intrauterine bleeding. In group A patients destined to abortion, the gestational sac development and corresponding protein synthesis fell before the fetal heart activity stopped; in spontaneous pregnancies, maternal serum HSCRP did not provide additional information for the management of threatened spontaneous abortion but warrants further research in assisted reproduction pregnancies.

    To maximize outcomes from endoscopic skull base surgery, careful early postoperative management is critically important. Standardized postoperative regimens are lacking. The type of reconstruction and presence and type of cerebrospinal fluid leak dictate management. If a leak is encountered intraoperatively, patients should avoid maneuvers that increase intracranial pressures for at least 1 month. Early postoperative care focuses on minimizing and managing nasal crusting. This article reviews the evidence in the literature on postoperative management, complications, and quality of life after surgery, and outlines our experience in the management of patients after endoscopic skull base surgery.

    BACKGROUND Ebstein-Barr virus (EBV) plays a critical role in nasopharynx cancer, which can be effectively monitored by serum levels of early antigen antibody (EA-IgA) and viral capsid antigen antibody (VCA-IgA). This study explored the diagnostic value of combined assays of sialic acid (SA), EA-IgA, and VCA-IgA via the expressional assay. MATERIAL AND METHODS A total of 42 nasopharynx cancer patients and 42 benign rhinitis and healthy controls were recruited in this study. Serum EA-IgA and VCA-IgA were tested by enzyme-linked immunosorbent assay (ELISA) and enzymatic assay of serum SA. Specificity and sensitivity of those 3 assays were compared. The diagnostic value of each parameter was evaluated by ROC curves. RESULTS All 3 indexes (SA, EA-IgA and VCA-IgA) showed elevated serum levels in nasopharynx cancer patients when compared to those with rhinitis, who had higher levels than healthy individuals. Concentrations of these factors were also positively correlated with the TNM staging of cancer. The sensitivity and specificity were 30.95% and 83.33% (in SA), 57.14% and 95.24% (in EA-IgA), and 76.19% and 92.86% (in VCA-IgA), respectively. VCA-IgA had the highest sensitivity among all 3 indexes. The combined assay increased the diagnostic sensitivity to 92.86% without compromising specificity. CONCLUSIONS SA, EA-IgA, and VCA-IgA levels were significantly elevated in nasopharynx patients' serum. The combined assay may have clinical value in diagnosis and monitoring.

    The effects of neostigmine and calcium pantothenate on electrical activity of the stomach and small intestine were studied in chronic experiments on rats after laparotomy with implantation of a probe into the jejunum and electrodes into different portions of the gastrointestinal tract. At the early terms after surgery, stimulation of endogenous acetylcholine release intensified electrical activity of the stomach, duodenum, and jejunum. Treatment with neostigmine and calcium pantothenate did not accelerate the recovery of the migrating myoelectrical complex, but promoted the recovery of the general intensity of action potential generation in the stomach and small intestine.

    The present work deals with the evaluation of a high-performance liquid chromatography laser-induced fluorescence (HPLC-LIF) technique developed in our laboratory for early detection of oral cancer from protein profiles of body fluids. The results show that protein profiles of serum samples from a given class of samples, say, normal, premalignant, or malignant, are statistically very close to each other, while profiles of members of any class are significantly different from other classes. The performance of the technique is evaluated by the use of sensitivity and specificity pairs, receiver operating characteristic (ROC) analysis, and Youden's Index. The technique uses protein profile differences in serum samples, registered by the HPLC-LIF technique. The study is carried out using serum samples from volunteers diagnosed as normal or premalignant clinically, and as malignant by histopathology. The specificities and sensitivities of the HPLC-LIF method at an ideal threshold (M-distance = 2) for normal, malignant, and premalignant classes are 100, 69.5, and 61.5%, and 86.5, 87.5, and 87.5% respectively.

    The aim of this study was to analyse the nested polymerase chain reaction (nested PCR) in human serum samples of patients with clinical manifestations of leptospirosis. The cases of leptospirosis were defined by the microagglutination test (MAT). The samples were collected in 2010. Of 1042 serum samples collected from 521 patients, 28 (5.4%) were considered positive cases of leptospirosis, and 493 (94.6%) were negative. Twenty-three confirmed cases had no MAT-detectable antibodies in the acute sample (mean of 5.6 days after onset). Nested PCR was positive in 22/23 (95.7%) patients during the acute phase of the disease, with negative results by MAT. Nested PCR was negative in all convalescent serum samples with positive results by MAT. All negative cases of leptospirosis were negative by nested PCR. The nested PCR is an alternative diagnostic tool for early detection of leptospires in sera during the first 7 days of the disease. PMID:24445157

    Despite the introduction of high-technology methods of detection and diagnosis, screening of primary liver cancer (PLC) remains imperfect. To diagnosis PLC earlier, Surface-enhanced Raman spectroscopy (SERS) coupled with cellulose-acetate membrane electrophoresis were introduced to separate human serum albumin and SERS spectra. Three groups (15 normal persons' samples, 17 hepatitis/cirrhosis samples, 15 cases of PLC) of serum albumin were tested. Silver colloid was used to obtain SERS spectra of human serum albumin. Principal component analysis (PCA) and linear discriminant analysis (LDA) were also employed for statistical analysis. The mean Raman spectra of three groups and the difference spectra of any two suggested that the albumin has changed in liver patients. Compared to normal groups, some Raman peaks have shifted or even disappeared in hepatitis/cirrhosis and PLCs groups. The sensitivity and specificity between PLCs and normal groups is 80% and 93.3%. Among hepatitis/cirrhosis and normal groups, the sensitivity is 88.2% and specificity is also 93.3%. Besides, the sensitivity and specificity between PLCs and hepatitis/cirrhosis groups is 86.7% and 76.5%. All the above data and results indicated that early screening of PLC is potential by SERS in different stages of liver disease before cancer occurs.

    Serum human placental lactogen (hPL) and human chorionic gonadotropin (hCG) were assayed and fetal crown-rump length (CRL) was determined by sonar in three groups of pregnant women--35 with uncomplicated pregnancies, 13 with insulin-dependent diabetes mellitus, and 21 who represented a general pregnancy population. Each patient had a regular cycle and recorded last menstrual period, ovulated spontaneously, and was delivered of a single live baby. Serum hPL concentrations within the range 0.01-0.80 microU/ml in patients in the first group gave estimates of gestation with an SD of 6.3 days which was the same as the SD derived from CRL measurements. When the hPL regression equation was applied to the diabetic mothers the difference between the gestational age estimated from hPL and that estimated from LMP had a mean value of - 0.9 days with an SD of 6.2 days; this difference was not significantly different from zero. The third group of patients had a mean difference between hPL and LMP derived gestational age of 0.7 days (+/- 6.7 SD). Serum hPL offers a method of estimating gestation sufficiently precise to be used as a practical alternative to sonar measurements of CRL.

    Biochemical effects of NOx on 60 workers (both genders) of nitric acid production were studied. The control group consisted of 61 nonexposed people employed elsewhere in the plant. Although the actual threshold limit valuetime weighted averages (TLV-TWA) were not exceeded in the specific conditions of our study, the subjects were exposed to NO2 and NO during several exposure episodes with peak maximal concentrations of 140 ppm and 515 ppm, respectively. Additional cross-week evaluation of several biochemical biomarkers in 15 NOx-exposed workers from one shift was performed. The objective of the study was to evaluate the value of serum Clara-cell protein (CC16) as a marker of bronchoalveolar epithelium activity. Antioxidant status was assessed by measuring activity of enzymes: glutathione peroxidase (GSH-Px), ceruloplasmin (Cp) in plasma, or superoxide dismutase (SOD), gluthatione S-transferase (GST), and nonenzymatic alpha-tocopherol in erythrocytes and thiobarbituric acid-reactive substances (TBARS) in plasma. Serum hyaluronic acid (HA) determining the connective tissue matrix status of airways, and beta2-microglobulin in serum (beta2M-S) and urine (beta2M-U) as a marker of renal function in occupational exposure to NOx were also employed. Exposure to NOx initiates peroxidative chain depleting of lipoprotein pool (alpha-tocopherol) in blood. Serum CC16 levels in NOx-exposed workers were found to be closely connected with alpha-tocopherol content. In NOx-exposed workers, the beta2M-S level was significantly higher than in the nonexposed ones, with the exception of smokers. Results of the cross-week study confirm cumulative systemic effects of NOx on several examined biomarkers. SOD and GST were found to be depleted. A transient higher level of HA after a 5-d shift significantly inversely correlated with CC16 level. The data imply that NOx-depleted levels of CC16 are detectable already after an 8-h shift. Our results demonstrate that even low NOx human exposure can

    Background Fibroblast growth factor 23 (FGF23) regulates mineral homeostasis. In developed renal dysfunction, FGF23 levels increase to maintain the phosphate excretion capacity. However, in diabetic patients with early-stage renal impairment, the FGF23 elevation is not very sensitive. We hypothesized that urinary phosphate (U-P)/serum FGF23 ratio would theoretically be an index that reflects the number of nephrons (nephron index). In this study, we determined whether the nephron index would be associated with renal function and vascular diseases in diabetic patients. Methods In total, 142 patients with diabetes mellitus were enrolled. The nephron index was calculated using the following formula: U-P (mg/day)/ serum FGF23 (pg/ml). Results The mean age was 63 ± 11 years and eGFR levels were 79.5 ± 25.4 ml/min/1.73 m2, respectively. Thirty patients had a medical history of macroangiopathy. The Nephron index was significantly decreased in subjects with macroangiopathy compared with those without macroangiopathy. A multivariate analysis of risk factors for macroangiopathy revealed that duration of diabetes, eGFR, and nephron index were significantly associated with a higher frequency of arteriosclerotic disease. Conclusion These findings suggest that a decrease in nephron index reflects early-stage renal impairment and is an independent risk factor of macroangiopathy in diabetic patients. PMID:27504998

    Although the effect of early social environments on maternal care in adulthood has been examined in detail, few studies have addressed the long-term effect on paternal care and its underlying neuroendocrine mechanisms. Here, using monogamous mandarin voles (Microtus mandarinus) that show high levels of paternal care, the effects of early bi-parental separation (EBPS) or neonatal paternal deprivation (NPD) on adult paternal behavior, serum corticosterone levels, and receptor mRNA expression in the nucleus accumbens (NAcc) and medial preoptic area (MPOA) were investigated. Compared to the parental care group (PC), we found that EBPS reduced crouching behavior and increased inactivity, self-grooming, and serum corticosterone levels in adult offspring; and NPD significantly reduced retrieval behavior and increased self-grooming behavior of offspring at adulthood. EBPS displayed more dopamine type I receptor (D1R) mRNA expression in the NAcc, but less oxytocin receptor (OTR) mRNA expression than PC in the MPOA. Both EBPS and NPD exhibited more mRNA expression of estrogen receptor alpha (ERα) than PC in the MPOA. In the EBPS group, increased serum corticosterone concentration was closely associated with reduced crouching behavior, and reduced expression of OTR was closely associated with altered crouching behavior and increased D1R expression. Our results provide substantial evidence that EBPS or NPD has long-term consequences and reduces paternal behavior in adult animals. Importantly the oxytocin system in the MPOA might interact with NAcc dopamine systems to regulate paternal behavior and EBPS may affect interactions between the MPOA and NAcc.

    Carcinoembryonic antigen (CEA) is well established tumor marker for colorectal cancers worldwide. Recent studies show that serum prolactin level is also raised in colorectal cancers. The purpose of the study is to evaluate the correlation of serum CEA and Prolactin with Dukes' staging of colorectal carcinomas. Between January 2013 and June 2013, Serum CEA and Serum Prolactin were measured by radioimmunoassay from 103 patients who were histopathologically diagnosed as colorectal carcinomas. Evaluation of the stages of the colorectal cancers was done on the basis of preoperative investigations and postoperative histopathology and correlated with Preoperative Serum CEA and Serum Prolactin. Results were presented as median value, range and percentage. Male to female ratio was 1.4:1 with median age of 42.26 years (range 17-78 years). Most of the patients in this series presented with carcinoma rectum (42%). Most of the patients (52%) were found in Dukes' stage C and 27% and 15% cases were found as Dukes' stage B and Dukes' stage D respectively. Stage of the disease is directly proportionate to percentage of the patient with high serum prolactin except early stage (Dukes' A-50%, Dukes' B-28.6%, Dukes' C-33.3% & Dukes' D-46.7%). Similarly serum CEA level is directly proportionate to tumor stage (Dukes' A-0%, Dukes' B-32%, Dukes' C-40.7% & Dukes' D-74.7%). A preoperative high serum CEA value suggests advanced disease either locally or with distant metastasis. In contrast preoperative high serum prolactin (hyperprolactinaemia) did not suggest advanced disease as it can be elevated even in early stage of disease. Serum CEA and Serum Prolactin both are valuable tumor markers but serum CEA could not be replaced by serum Prolactin. Serum Prolactin may be a helpful marker in earlier stages of the colorectal cancer.

    The hormone progesterone is essential for proper embryonic development. The objective of this study was to examine the relationship between recipient serum concentrations of progesterone, at the time of embryo transfer and at conceptus recovery, on conceptus development from in vivo- or in vitro-produced embryos. Embryos were produced in vivo by superovulation of Holstein cows (IVO; n = 17) or in vitro with either serum-containing (IVPS; n = 27) or serum-restricted medium (IVPSR; n = 34). Single grade I blastocysts from each embryo production system were transferred into heifers on day 7 of development. Conceptuses were recovered on day 17 of gestation and classified as complete, degenerated, or no conceptus. Compared with the IVO group, in vitro-produced embryos had more (P = 0.055) degenerated conceptuses (IVO, 0%; IVPS, 18.5%; and IVPSR, 20.6%). There were no differences in progesterone concentrations at the time of transfer when recipients received either male or female embryos (P > 0.05). Progesterone concentrations in recipients receiving in vivo-produced embryos were higher (P < 0.05; 3.74 ± 0.4 ng/mL; least-squares mean ± standard error of the mean) on day 7 compared with those receiving in vitro-produced embryos (IVPS, 2.4 ± 0.2; IVPSR, 2.58 ± 0.3 ng/mL). However, there was no difference in progesterone concentration on day 7 between treatment groups for heifers from which short conceptuses (≤194 mm) were recovered on day 17. In contrast, when longer (>194 mm) conceptuses were recovered on day 17, heifers receiving in vitro-produced embryos had lower (P = 0.05) serum concentrations of progesterone on day 7 compared with those receiving in vivo-produced embryos (IVPS, 2.2 ± 0.5; IVPSR, 2.3 ± 0.5; IVO, 3.9 ± 0.5 ng/mL). In conclusion, differences in autonomy may exist between in vitro- and in vivo-produced embryos during the period of conceptus elongation with in vitro-produced embryos relying more on intrinsic factors to influence elongation.

    Summary Background Hepatitis B e antigen (HBeAg) seroconversion is an important hallmark in the natural course of chronic hepatitis B. This study was designed to predict early HBeAg seroconversion within 1 year, by not only biochemical and virological markers, but also pathological parameters in patients with chronic hepatitis B. Material/Methods In a retrospective cohort study, 234 patients with HBeAg were reviewed for demographic, biochemical, virological and pathological data at the time of liver biopsy. Then, the patients who accomplished HBeAg seroconversion within 1 year thereafter were compared with those who did not, for sorting out factors predictive of early HBeAg seroconversion. Results Early HBeAg seroconversion occurred in 58 (24.8%) patients. In univariate analysis, factors predictive of early HBeAg seroconversion were: alanine aminotransferase (ALT) (p=0.002), IP-10 (p=0.029), HBsAg (p=0.003), HBeAg (p<0.001), HBV DNA (p=0.001), HBcrAg (p=0.001), core-promoter mutations (p=0.040), fibrosis (p=0.033) and lobular inflammation (p=0.002). In multivariate analysis, only serum HBeAg levels <100 Paul Ehrlich Institute (PEI) U/ml and grades of lobular inflammation ≥2 were independent factors for early HBeAg seroconversion (odds ratio 8.430 [95% confidence interval 4.173–17.032], p<0.001; and 4.330 [2.009–9.331], p<0.001; respectively). Conclusions HBeAg levels < 100 PEIU/ml combined with grades of lobular inflammation ≥2 are useful for predicting early HBeAg seroconversion. In patients without liver biopsies, high ALT levels (≥200 IU/L) can substitute for lobular inflammation (grades ≥2). PMID:23197230

    Serum protein profiles of patients with bacterial sepsis from the day of diagnosis until recovery/mortality were compared from early to late stages in response to severe sepsis using two dimensional electrophoresis. The proteins exhibiting changes during the course of sepsis (20‑28 day mortality) were selected and identified by matrix‑assisted laser desorption ionization‑time of flight‑tandem mass spectrometry. Among the proteins identified, haptoglobin (Hp), transthyretin (TTR), orosomucoid 1/α1 acid glycoprotein (ORM1), α1 antitrypsin (A1AT), serum amyloid A (SAA) and S100A9 exhibited differential expression patterns between survivors (S; n=6) and non‑survivors (NS; n=6), particularly during the early stages of sepsis. Expression factors (EFs), taken as the ratio between the NS and S during early stages, showed ratios of Hp, 0.39 (P≤0.012); TTR, 3.96 (P≤0.03); ORM1, 0.69 (P≤0.79); A1AT, 0.92 (P≤0.87) and SAA, 0.69 (P≤0.01). S100A9, an acute phase protein, exhibited an EF ratio of 1.68 (P≤0.004) during the end stages of sepsis. A delayed rise in levels was observed in Hp, A1AT, ORM1, S100A9 and SAA, whereas TTR levels increased during the early stages of sepsis in NS. Analysis of inflammatory responses in the early stages of sepsis revealed increased mRNA expression in leukocytes of interleukin (IL)‑6 (EF, 2.50), IL‑10 (EF, 1.70) and prepronociceptin (EF, 1.6), which is a precursor for nociceptin in NS compared with S, and higher Toll‑like receptor‑4 (EF, 0.30) levels in S compared with NS. Therefore, a weaker acute phase response in the early stages of sepsis in NS, combined with an inefficient inflammatory response, may contribute to sepsis mortality. PMID:27082932

    In the postoperative period, 47% to 75% of the patients report some degree of pain. This study aimed to evaluate pain in the pre and postoperative period of patients submitted to craniotomy. This prospective research was carried out at the neurosurgery unit of a large Brazilian hospital. For a quantitative evaluation of pain, the verbal numeric 0-10 rating scale was used. Forty patients with a mean age of 36 years were evaluated. In the preoperative period, 34 (85%) patients indicated headache as the main cause of pain. In the postoperative period, 37 (93%) patients complained of pain while three (7%) reported absence of pain. Pain peaks were observed on the 2nd postoperative day, when 12 (32%) of the patients reported severe pain and 10 (27%) moderate pain. Absence of severe pain occurred after the 8th postoperative day. It was concluded that protocols of analgesia in craniotomy are needed, such as training nurses to better evaluate and handle pain. PMID:16211171

    The effective relief of pain is of the utmost importance to anyone treating patients undergoing surgery. Pain relief has significant physiological benefits; hence, monitoring of pain relief is increasingly becoming an important postoperative quality measure. The goal for postoperative pain management is to reduce or eliminate pain and discomfort with a minimum of side effects. Various agents (opioid vs. nonopioid), routes (oral, intravenous, neuraxial, regional) and modes (patient controlled vs. “as needed”) for the treatment of postoperative pain exist. Although traditionally the mainstay of postoperative analgesia is opioid based, increasingly more evidence exists to support a multimodal approach with the intent to reduce opioid side effects (such as nausea and ileus) and improve pain scores. Enhanced recovery protocols to reduce length of stay in colorectal surgery are becoming more prevalent and include multimodal opioid sparing regimens as a critical component. Familiarity with the efficacy of available agents and routes of administration is important to tailor the postoperative regimen to the needs of the individual patient. PMID:24436674

    Postoperative spinal wound infection is a potentially devastating complication after operative spinal procedures. Despite the utilization of perioperative prophylactic antibiotics in recent years and improvements in surgical technique and postoperative care, wound infection continues to compromise patients’ outcome after spinal surgery. In the modern era of pending health care reform with increasing financial constraints, the financial burden of post-operative spinal infections also deserves consideration. The aim of our work is to give to the reader an updated review of the latest achievements in prevention, risk factors, diagnosis, microbiology and treatment of postoperative spinal wound infections. A review of the scientific literature was carried out using electronic medical databases Pubmed, Google Scholar, Web of Science and Scopus for the years 1973-2012 to obtain access to all publications involving the incidence, risk factors, prevention, diagnosis, treatment of postoperative spinal wound infections. We initially identified 119 studies; of these 60 were selected. Despite all the measures intended to reduce the incidence of surgical site infections in spine surgery, these remain a common and potentially dangerous complication. PMID:26605028

    A postoperative haemorrhage is a common and serious complication of a neurosurgical procedure. It usually occurs at the site of the surgery, but on occasion a postoperative haematoma is found at a distance from the previous craniotomy. Multiple postoperative haemorrhages are extremely rare. We report the case of a 63-year-old woman, operated on for the removal of a supratentorial astrocytoma, who developed in the early post-operative period multiple bilateral intracerebral haematomas without involvement of the surgical bed.

    Background: A recent study reported a positive association between elevated serum levels of angiopoietin-like protein 2 (ANGPTL2) and the development of type 2 diabetes in a general population. However, the relationship of serum ANGPTL2 levels with the risk of developing gestational diabetes mellitus (GDM) has not been reported to date. The aim of this study was to investigate the change of maternal serum ANGPTL2 concentrations in the first trimester of pregnancy and to determine whether ANGPTL2 is a biomarker for subsequent GDM development. Methods: We conducted a prospective, nested case-control study in a pregnancy cohort. First-trimester ANGPTL2 levels were measured using a high-resolution assay in 89 women who subsequently developed GDM and in a random sample of 177 women who remained euglycemic throughout the pregnancy. Median ANGPTL2 levels were compared using Mann-Whitney U-test. Logistic regression was used to compute unadjusted and multivariable-adjusted odds ratios for developing GDM among ANGPTL2 quartiles. Results: The serum levels of ANGPTL2 was higher in women with GDM than that in women without GDM (3.06 [2.59, 3.65] ng/ml vs. 2.46 [2.05, 2.96] ng/ml, P = 0.003). Fasting blood glucose was higher in women with GDM than that in women without GDM (5.0 ± 0.9 mmol/L vs. 4.4 ± 0.6 mmol/L, P < 0.001). Glucose challenge test showed that the blood glucose was higher in women with GDM than that in women without GDM (9.1 ± 3.5 mmol/L vs. 6.2 ± 1.2 mmol/L, P < 0.001). A multivariate model adjusted for baseline characteristics, medical complications, and gestational characteristics revealed that the risk of developing GDM among women in Q4 compared with Q1 was 2.90-fold more likely to develop GDM later in pregnancy. Conclusions: At 11–13 weeks in pregnancies that develop GDM, the serum concentration of ANGPTL2 is increased, and it can be combined with maternal factors to provide effective early screening for GDM.

    Although dental implant placements have high success rates and a low incidence of morbidity, post-operative pain and complications with the healing process have been reported. There is little guidance available regarding optimal pre- and post-operative management of dental implant placement. This first paper discusses the mechanisms of pain associated with dental implant placement and offers guidance to clinicians on optimal pre- and post-operative pain management regimes. The second paper aims to discuss pre- and post-operative means of reducing the risk of early healing complications. PMID:25104691

    Amyloid A (SAA) and procalcitonin (PCT) have been reported as useful indicators of inflammation. Our aim was to assess the utility of SAA and PCT in establishing the severity of acute pancreatitis in comparison to C-reactive protein (CRP): Thirty-one patients with acute pancreatitis enrolled within 24 hr from the onset of pain and 31 healthy subjects were studied. Nineteen patients had mild acute pancreatitis, and 12 had severe pancreatitis. Serum SAA, PCT, and CRP were measured in all subjects at admission and, in acute pancreatitis patients, during the following five days. Patients with acute pancreatitis had serum concentrations of SAA, PCT, and CRP significantly higher (P < 0.001) than those of healthy subjects during the entire study period. Using cutoff values ranging from 240 to 250 mg/liter for SAA, from 0.252 to 0.255 ng/ml for PCT, and from 12.8 to 12.9 mg/dl for CRP, the sensitivity (calculated on patients with severe pancreatitis), the specificity (calculated on patients with mild pancreatitis), and the efficiency (calculated as the percentage of correct classifications) were 76.8%, 69.3%, and 72.4% for SAA; 21.7%, 83.2%, and 58.2% for PCT; and 60.9%, 89.1%, and 77.6% for CRP. In conclusion, the sensitivity of SAA is significantly higher than that of PCT and CRP in assessing the severity of pancreatitis, whereas PCT and CRP had a specificity significantly higher than SAA. The accuracy and efficiency were similar for SAA and CRP, and both these markers had an accuracy and efficiency significantly higher than those of PCT.

    The toxicity of decabromodiphenyl ether (BDE-209) has been reported in several studies. However, there is not much known about the toxicological biomarkers that characterize BDE-209 exposure. In this study, we subcutaneously exposed mice to 0.025 mg/kg/day BDE-209 on postnatal days 1‑5 and sacrificed the animals at 12 weeks of age (day 84). Flow injection analysis and hydrophilic interaction chromatography-triple quadrupole mass spectrometry were used to determine the serum metabolomes of these mice in order to characterize the effects of BDE-209 exposure. Data analysis showed a good separation between control and exposed mice (R(2) = 0.953, Q(2) = 0.728, and ANOVA of the cross‑validated residuals (CV‑ANOVA): P‑value = 0.0317) and 54 metabolites were identified as altered in the exposed animals. These were selected using variable importance (VIP) and loadings scaled by a correlation coefficient criteria and orthogonal partial least squares discriminant analysis (OPLS‑DA). BDE‑209‑exposed mice showed lower levels of long-chain acylcarnitines and citrate cycle-related metabolites, and higher levels of some amino acids, long-chain phospholipids, and short-chain acylcarnitines. The disruption of fatty acid, carbohydrate, and amino acid metabolism observed in the serum metabolome might be related to the previously observed impaired spermatogenesis in mice with early postnatal exposure to a low dose of BDE-209.

    Community-acquired pneumonia (CAP) is amongst the leading causes of death worldwide. As inflammatory markers, cytokines can predict outcomes, if interpreted together with clinical data and scoring systems such as CURB-65, CRB, and Acute Physiology and Chronic Health Evaluation II (APACHE II). The aim of this study was to determine the impact of inflammatory biomarkers on the early mortality of hospitalized CAP patients. Twenty-seven CAP patients needing hospitalization were enrolled for the study and samples of interleukin-1 (IL-1) and interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), C-reactive protein (CRP), and homocystein were collected at the time of admission (day 1) as well as on the seventh day of the treatment. There was a significant reduction in the levels of IL-6 between the first and the second collections. Median IL-6 values decreased from 24 pg/mL (day 1) to 8 pg/mL (day 7) (P=0.016). The median levels of TNF-α were higher in patients: i) with acute kidney injury (AKI) (P=0.045), ii) requiring mechanical ventilation (P=0.040), iii) with short hospital stays (P=0.009), iv) admitted to the intensive care unit (ICU) (P=0.040), v) who died early (P=0.003), and vi) with worse CRB scores (P=0.013). In summary, IL-6 and TNF-α levels were associated with early mortality of CAP patients. Longer admission levels demonstrated greater likelihood of early death and overall mortality, necessity of mechanical ventilation, and AKI. PMID:25714883

    The fat-soluble vitamin E comprises the 8 structurally related compounds (congeners) α-, β-, γ-, and δ-tocopherol (with a saturated side chain) and α-, β-, γ-, and δ-tocotrienol (with a 3-fold unsaturated side chain). Little is known regarding the blood and liver concentrations of the 8 vitamin E congeners during the transition from pregnancy to lactation in dairy cows. We thus quantified tocopherols (T) and tocotrienols (T3) in serum and liver and hepatic expression of genes involved in vitamin E metabolism in pluriparous German Holstein cows during late gestation and early lactation and investigated whether dietary supplementation (from d 1 in milk) with conjugated linoleic acids (CLA; 100g/d; each 12% of trans-10,cis-12 and cis-9,trans-11 CLA; n=11) altered these compared with control-fat supplemented cows (CTR; n=10). Blood samples and liver biopsies were collected on d -21, 1, 21, 70, and 105 (liver only) relative to calving. In both groups, the serum concentrations of αT, γT, βT3, and δT3 increased from d -21 to d 21 and remained unchanged between d 21 and 70, but were unaffected by CLA. The concentrations of the different congeners of vitamin E in liver did not differ between the CTR and the CLA groups. In both groups, the concentrations of the vitamin E forms in liver changed during the course of the study. The hepatic mRNA abundance of genes controlling vitamin E status did not differ between groups, but α-tocopherol transfer protein and tocopherol-associated protein mRNA increased with time of lactation in both. In conclusion, the concentrations of vitamin E congeners and the expression of genes related to vitamin E status follow characteristic time-related changes during the transition from late gestation to early lactation but are unaffected by CLA supplementation at the dosage used.

    Femoroacetabular impingement (FAI) has been recognized as a common cause of pain, limited range of motion, and development of early osteoarthritis of the hip in adolescents and adults. Current surgical approaches include femoral osteochondroplasty, acetabular rim resection, and reattachment of torn labrum as either open surgical or arthroscopic techniques as well as periacetabular osteotomy. Conventional radiographs are routinely obtained in the postoperative setting. In addition, MRI serves for work-up in patients with persistent or recurrent groin pain after surgery. Inappropriate correction of the underlying femoral or acetabular osseous abnormality, insufficiency fractures of the femoral neck due to bone resection, intra-articular adhesions, ongoing joint degeneration including advanced cartilage damage, iatrogenic cartilage injury, retear of the labrum, rarely avascular necrosis of the femoral head, defects of the hip joint capsule, or heterotopic ossification might be observed after surgery for FAI.

    Leptin, an adipocyte-derived hormone, plays an important role in reproduction and angiogenesis. Studies examining leptin in preeclampsia are inconsistent, possibly because of small sample sizes and variability in sampling and outcome. We conducted a nested case-control study to examine associations between serum leptin (measured: 9-26 weeks gestation) and preeclampsia among 430 primiparous preeclamptic women and 316 primiparous normotensive controls from the Danish National Birth Cohort. Median (interquartile range) leptin concentrations were calculated. Associations between leptin and preeclampsia (blood pressure ≥140/90 mm Hg), term preeclampsia (preeclampsia and delivery ≥37 weeks gestation), or preterm preeclampsia (preeclampsia and delivery <37 weeks gestation) were examined using generalized linear models adjusting for body mass index, gestational age at blood draw, maternal age, smoking, and socio-occupational status. As leptin is increased in obese women and the risk of preeclampsia increases with body mass index, we used the Sobel test to examine whether leptin is a mediator of this relationship. After adjustments, leptin concentrations were significantly higher in women with preeclampsia (30.5 [24.6]; P=0.0117) and term preeclampsia (30.4 [24.9]; P=0.0228) compared with controls (20.9 [28.3]). There was no significant difference between preterm preeclampsia (30.6 [23.4]; P=0.2210) and controls. Leptin is a possible mediator of the association between body mass index and preeclampsia (P=0.0276). Leptin concentrations are higher in women with preeclampsia compared with normotensive controls and may mediate some of the relationship between body mass index and preeclampsia.

    In 2003, we reported on 2 cases of nonproliferative and proliferative diabetic retinopathy, subsequent to HbA1c reduction by intensive insulin therapy (so-called early worsening of diabetic retinopathy). This acute condition could partly be reversed by discontinuation of intensive insulin therapy, whereby glycemia increased and serum IGF-1 concentration decreased [Ophthalmologica 2003;217:373-377]. On review 7 years later, both type-2 diabetic patients were on insulin therapy but had failed to achieve good glycemic control. One patient had mild background retinopathy on both eyes, with visual acuity of 1.0 and 0.7 after cataract extraction plus intravitreal triamcinolone injection. The 2nd patient was blind in one eye from secondary glaucoma due to vitrectomy and silicone oil filling; the fellow eye displayed residual retinal neovascularization with a hyaloid membrane and a visual acuity of 0.5. Hence, early worsening as opposed to late worsening of diabetic retinopathy seems to benefit from therapeutic suppression of growth factor action.

    The onset of jaundice following a surgical operation sometimes raises difficult problems. It is rarely due to hemolysis, infective hepatitis or decomposated cirrhosis of the liver. One should seek as a routine hepatitis due to halotane. However the most frequent cause is "benign postoperative cholestasis". This variety of jaundice presents in the form of an icterus due to conjugated bilirubine with often a large increase in alkaline phosphatase levels. The ocurse is variable. Almost always due to severe surgical or septic trauma, accompanied by shock and/or anoxia, it raises difficult diagnostic problems. The clinical and physiopathological aspects of benign postoperative cholestasis are recalled. One should remember, above all, that this is not an autonomous clinical entity but the sign of local or general complications which should be sought carefully.

    Postoperative lymphocele is a well-documented complication of gynecological operations involving pelvic and retroperitoneal lymph node dissection. It is not uncommon following renal transplantation. We report a 77-year-old woman with a lymphocele which developed 4 months after panhysterectomy. Diagnosis was by CT scan, confirmed by aspiration and cytology. Percutaneous drainage and sclerotherapy with tetracycline was curative. This appears to be the treatment of choice for lymphocele and is superior to repeated aspirations and surgical intervention, the current usual treatment.

    Early diagnosis and prevention of Rhodococcus equi pneumonia in foals represent important goals for equine clinicians. Recent protocols for diagnosis and treatment of Rhodococcosis in foals typically rely on a multimodal approach based on sonographic evidence suggestive of pyogranulomas, sonographic abscess scores and laboratory findings including plasma fibrinogen concentrations, blood biochemistry testing and platelet and leukocyte counts. The aim of this study was to assess the utility of weekly testing of serum amyloid A (SAA) and plasma fibrinogen concentrations in foals to achieve early diagnosis of R. equi pneumonia prior to the onset of clinical signs. This testing was used to simulate a clinically practical screening procedure and compared with thoracic ultrasonography performed in parallel. The present study suggests that SAA does not represent a reliable early marker of Rhodococcosis when plasma concentrations are tested weekly. However, when clinical signs of R. equi pneumonia are present, SAA concentrations may allow clinicians to obtain 'real-time' indications concerning both the progress of infection and the effectiveness of therapy. This study raises the possibility that plasma fibrinogen monitoring starting at 1 week of age and repeated on a weekly basis, could serve as a screening test allowing clinicians to identify foals as suspected of R. equi infection. Future investigations regarding both physiological plasma fibrinogen concentrations in foals as well as fibrinogen kinetics in foals affected with R. equi pneumonia, including the establishment of appropriate reference intervals for the test method employed in this study, will be necessary in order to clarify this possibility.

    The purpose of this paper is to describe what I have studied and experienced, mainly regarding the control and prediction of the postoperative edema; how to achieve an agreeable recovery and give positive support to the patient, who in turn will receive pleasant sensations that neutralize the negative consequences of the surgery.After the skin is lifted, the drainage flow to the flaps is reversed abruptly toward the medial part of the face, where the flap bases are located. The thickness and extension of the flap determines the magnitude of the post-op edema, which is also augmented by medial surgeries (blepharo, rhino) whose trauma obstruct their natural drainage, increasing the congestion and edema. To study the lymphatic drainage, the day before an extended face lift (FL) a woman was infiltrated in the cheek skin with lynfofast (solution of tecmesio) and the absorption was observed by gamma camera. Seven days after the FL she underwent the same study; we observed no absorption by the lymphatic, concluding that a week after surgery, the lymphatic network was still damaged. To study the venous return during surgery, a fine catheter was introduced into the external jugular vein up to the mandibular border to measure the peripheral pressure. Following platysma plication the pressure rose, and again after a simple bandage, but with an elastic bandage it increased even further, diminishing considerably when it was released. Hence, platysma plication and the elastic bandage on the neck augment the venous congestion of the face. There are diseases that produce and can prolong the surgical edema: cardiac, hepatic, and renal insufficiencies, hypothyroidism, malnutrition, etc. According to these factors, the post-op edema can be predicted, the surgeon can choose between a wide dissection or a medial surgery, depending on the social or employment compromises the patient has, or the patient must accept a prolonged recovery if a complex surgery is necessary.

    Assessment of influenza virus disease progression and efficacy of antiviral therapy in the widely used mouse models relies mostly on body weight loss and lung virus titers as markers of disease. However, both parameters have their shortcomings. Therefore, the aim of our study was to find non-invasive markers in the murine model of severe influenza that could detect disease early and predict disease outcome. BALB/c mice were lethally infected with influenza A(H1N1)pdm09 virus and serum samples were collected at various time points. Enzyme-linked immunosorbent assays were performed to quantify amounts of serum amyloid A (SAA), C-reactive protein, complement 3, transferrin, corticosterone, prostaglandin E2, H2O2, and alpha-2,6-sialyltransferase. We found that SAA was the most promising candidate with levels acutely and temporarily elevated by several hundred-fold 3 days post virus inoculation. Upon treatment with oseltamivir phosphate, levels of SAA were significantly decreased. High levels of SAA were associated with poor disease prognosis, whereas body weight loss was not as a reliable predictor of disease outcome. SAA levels were also transiently increased in BALB/c mice infected with influenza A(H3N2) and influenza B virus, as well as in C57BL/2, Swiss-Webster, and DBA.2 mice infected with influenza A(H1N1)pdm09 virus. High levels of SAA often, but not always, were associated with disease outcome in these other influenza virus mouse models. Therefore, SAA represents a valid biomarker for influenza disease detection in all tested mouse strains but its prognostic value is limited to BALB/c mice infected with influenza A(H1N1)pdm09 virus.

    Background Matrix metalloproteinase-9 (MMP-9) is an enzyme implicated in the pathogenesis of renal diseases. Renal involvement is the principal cause of morbidity and mortality in children with Henoch-Schönlein purpura (HSP). Objectives The aim of this study was to evaluate whether serum and urinary MMP-9 levels are associated with renal involvement in HSP Patients and Methods We evaluated 40 children with HSP (patient group) and 27 healthy volunteer children (control group). The patient group was divided into two subgroups based on the presence or absence of nephritis. Nephritis was defined as the existence of hematuria and/or proteinuria. All anthropometric data, physical examination findings, blood pressure, and laboratory parameters were recorded. The serum and urine samples were analyzed to determine the MMP-9 levels three days after the initial phase of the disease. Results The mean age was 7.65 ± 3.41 (range 2 - 16) years in the patient group and 9.52 ± 3.91 (range 2 - 16) years in the control group. Henoch-Schonlein purpura nephritis (HSPN) was identified in eight patients. There was no significant difference in the serum MMP-9 levels between the HSPN subgroup and the controls (P > 0.05). However, there were significant differences in the urinary MMP-9 levels between the HSP subgroup and the control group (P < 0.05), with the urinary MMP-9 levels being significantly higher in patients in the HSP subgroup (P = 0.001). Further, the urinary MMP-9 levels were significantly higher in the patients with nephritis than in the patients without nephritis (P = 0.001) and the controls (P = 0.001). The optimal cut-off point (sensitivity; specificity) of the urinary MMP-9 level for the diagnosis of HSPN was 94.7 pg/mL. Conclusions The levels of MMP-9 in the urine were remarkably high in patients with HSPN. This non-invasive marker may therefore be an important indicator for the early diagnosis of nephritis in children with HSP.

    The purpose of the present study was to assess the influence of preoperative activity of rheumatoid arthritis (RA) on early postoperative anterior chamber inflammation after phacoemulsification and intraocular lens implantation. Twenty-three eyes in 18 patients were included in our study. On the first postoperative day, anterior chamber inflammation was observed in 11 eyes (47.8%). Five days after surgery, we found postoperative inflammation only in 1 eye (4.3%). Keratic precipitates were observed in 1 eye (4.3%) on the second postoperative day. We found no correlation between the extent of anterior chamber inflammation and the preoperative activity of RA. Postoperative anterior chamber inflammation was also not associated with the medical management of RA.

    In a review paper, an analysis of publications in the world literature on the problem of acute postoperative pain in neurosurgical patients who underwent craniotomy is performed. Is shown that problem of acute postoperative pain in patients after craniotomy was underestimated for a long time. Mistakenly was thought that these patients do not experience any pain in the early postoperative period. Results of recent studies have shown that up to 80% of these patients may experience acute pain in the range from mild to severe. Unarrested postoperative pain could cause a number of serious secondary complications. This article demonstrates basic approaches to the prevention and treatment of acute postoperative pain in neurosurgical patients after craniotomy--first of all, the use of narcotic analgesics, NSAIDs, and other approaches.

    Conversion disorder is a psychiatric disorder in which psychological stress causes neurologic deficits. A 28-year-old female surgical patient had uneventful general anesthesia and emergence but developed conversion disorder 1 hour postoperatively. She reported difficulty speaking, right-hand numbness and weakness, and right-leg paralysis. Neurologic examination and imaging revealed no neuronal damage, herniation, hemorrhage, or stroke. The patient mentioned failing examinations the day before surgery and discontinuing her prescribed antidepressant medication, leading us to diagnose conversion disorder, with eventual confirmation by neuroimaging and follow-up examinations.

    Postoperative extradural hematoma (POEH) is a possible complication after head surgery, often neglected in the literature. In a single surgeon experience we found 13 cases of POEH (0.8%). We distinguished two subtypes: (1) larger hematomas (>40 cc) with typical features and overt clinical picture that always needed evacuation, and (2) smaller hematomas (<40 cc) with insidious clinical onset and different radiological features compared with traumatic and spontaneous extradural hematomas. On the basis of our experience, we propose that clinical picture and radiologic appearance lead the decision between conservative or interventional treatment of type II hematomas.

    Abstract Statins have beneficial effects on cerebral circulation and brain parenchyma during ischemic stroke and reperfusion. The primary hypothesis of this randomized parallel trial was that treatment with 80 mg/day of atorvastatin administered early at admission after acute atherosclerotic ischemic stroke could reduce serum levels of markers of immune-inflammatory activation of the acute phase and that this immune-inflammatory modulation could have a possible effect on prognosis of ischemic stroke evaluated by some outcome indicators. We enrolled 42 patients with acute ischemic stroke classified as large arteries atherosclerosis stroke (LAAS) randomly assigned in a randomized parallel trial to the following groups: Group A, 22 patients treated with atorvastatin 80 mg (once-daily) from admission day until discharge; Group B, 20 patients not treated with atorvastatin 80 mg until discharge, and after discharge, treatment with atorvastatin has been started. At 72 hours and at 7 days after acute ischemic stroke, subjects of group A showed significantly lower plasma levels of tumor necrosis factor-α, interleukin (IL)-6, vascular cell adhesion molecule-1, whereas no significant difference with regard to plasma levels of IL-10, E-Selectin, and P-Selectin was observed between the 2 groups. At 72 hours and 7 days after admission, stroke patients treated with atorvastatin 80 mg in comparison with stroke subjects not treated with atorvastatin showed a significantly lower mean National Institutes of Health Stroke Scale and modified Rankin scores. Our findings provide the first evidence that atorvastatin acutely administered immediately after an atherosclerotic ischemic stroke exerts a lowering effect on immune-inflammatory activation of the acute phase of stroke and that its early use is associated to a better functional and prognostic profile.

    Laminins are glycoproteins found in basement membranes where they play a vital role in tissue architecture and cell behavior. Previously, we reported the association of two polymorphisms (rs659822 and rs944895) in the laminin alpha5 (LAMA5) gene with anthropometric traits, fasting lipid profile, and glucose levels in pre-menopausal women and elderly subjects. Furthermore, studies in mice showed that Lama5 is involved in organogenesis and placental function during pregnancy. The objective of this study was to investigate whether rs659822 and/or rs944895 are associated with inter-individual variability in birth weight as well as anthropometric traits and metabolic phenotypes in children. Two hundred and eighty nine healthy children aged 7-12 yr of European, Hispanic, and African-American ancestry were studied. Co-dominant models adjusted for genetic admixture, age, gender, and stages of puberty were used to test for the association of the polymorphisms with each trait. Our analysis showed significant associations of rs659822 with fasting plasma glucose levels (P = 0.0004) and of rs944895 with fasting serum triglycerides (P = 0.004) after Bonferroni correction for multiple testing. Our results corroborate our previous findings that genetic variants in LAMA5 contribute to variation in metabolic phenotypes and provide evidence that this may occur early in life. PMID:27625828

    Improving postoperative return of bowel function after abdominal surgery is an important nursing and medical goal. One promising intervention to achieve this goal is to have patients chew gum several times per day in the early postoperative period to stimulate the cephalic-vagal reflex and bowel peristalsis. A study to determine if return of gastrointestinal function after abdominal surgery could be hastened by the simple intervention of chewing gum or sucking on hard candy three times per day is described.

    Diabetes insipidus (DI) after endoscopic transsphenoidal surgery (ETSS) can lead to increased morbidity, longer hospital stays, and increased medication requirements. Predicting which patients are at high risk for developing DI can help direct services to ensure adequate care and follow-up. The objective of this study was to review our institution's experience with ETSS and determine which clinical/laboratory variables are associated with DI in this patient population. The authors wanted to see if there was an easily determined single value that would help predict which patients develop DI. This represents the largest North American series of this type. We retrospectively reviewed the charts of patients who had undergone ETSS for resection of sellar and parasellar pathology between 2006 and 2011. We examined patient and tumor characteristics and their relationship to postoperative DI. Out of 172 endoscopic transsphenoidal surgeries, there were 15 cases of transient DI (8.7%) and 14 cases of permanent DI (8.1%). Statistically significant predictors of postoperative DI (p < 0.05) included tumor volume and histopathology (Rathke's cleft cyst and craniopharyngioma). Significant indicators of development of DI were postoperative serum sodium, preoperative to postoperative change in sodium level, and urine output prior to administration of 1-deamino-8-D-arginine vasopressin. An increase in serum sodium of ≥2.5 mmol/L is a positive marker of development of DI with 80% specificity, and a postoperative serum sodium of ≥145 mmol/L is a positive indicator with 98% specificity. Identifying perioperative risk factors and objective indicators of DI after ETSS will help physicians care for patients postoperatively. In this large series, we demonstrated that there were multiple perioperative risk factors for the development of DI. These findings, which are consistent with other reports from microscopic surgical series, will help identify patients at risk for diabetes insipidus

    Pancreatic cancer is an aggressive tumor with a dismal prognosis, biomarkers that can detect tumor in its early stages when it may be amenable to curative resection may improve prognosis. At present, serum CA 19-9 is the only validated tumor marker in widespread clinical use, but precise knowledge of its role in pancreatic cancer diagnosis, staging, determining resectability, response to chemotherapy and prognosis remains limited. A comprehensive search was performed using PubMed with keywords "pancreatic cancer" "tumor markers" "CA 19-9" "diagnosis" "screening" "prognosis" "resectability" and "recurrence". All English language articles pertaining to the role of CA 19-9 in pancreatic cancer were critically analyzed to determine its utility as a biomarker for pancreatic cancer. Serum CA 19-9 is the most extensively studied and clinically useful biomarker for pancreatic cancer. Unfortunately, CA 19-9 serum level evaluation in pancreatic cancer patients is limited by poor sensitivity, false negative results in Lewis negative phenotype (5-10%) and increased false positivity in the presence of obstructive jaundice (10-60%). Serum CA 19-9 level has no role in screening asymptomatic populations, and has a sensitivity and specificity of 79-81% and 82-90% respectively for the diagnosis of pancreatic cancer in symptomatic patients. Pre-operative CA 19-9 serum level provide useful prognostic information as patients with normal CA 19-9 serum levels (<37 U/ml) have a prolonged median survival (32-36 months) compared to patients with elevated CA 19-9 serum levels (>37 U/ml) (12-15 months). A CA 19-9 serum level of <100 U/ml implies likely resectable disease whereas levels >100 U/ml may suggest unresectablity or metastatic disease. Normalization or a decrease in post-operative CA 19-9 serum levels by ≥20-50% from baseline following surgical resection or chemotherapy is associated with prolonged survival compared to failure of CA 19-9 serum levels to normalize or an

    Twenty-eight patients underwent fiberoptic T-tube tract choledochoscopy for the diagnosis, management, and treatment of filling defects seen on postoperative T-tube cholangiograms. In 22 patients, 59 retained stones were treated by extraction. In six other patients with diagnostic problems arising from cholangiogram defects, the diagnosis was made by direct vision and biopsy specimen examination. There were multiple papillary adenocarcinomas in one patient, and normal mucosal folds in two patients. The procedure was accompanied by a low complication rate, with two patients developing pancreatitis and five patients developing transient fever. The advantages of the procedure are a direct examination of the biliary tree with the facility to remove stones and biopsy lesions under direct vision. PMID:7294933

    Postoperative nausea and vomiting (PONV) is a long-standing issue, not a new concept in anesthesiology. Despite many studies over the last several decades, PONV remains a significant problem due to its complex mechanism. This review presents a summary of the mechanism underlying the pathogenesis of PONV, focusing on preventive treatment, particularly the use of new drugs. In addition, we discuss the latest meta-analysis results regarding correct clinical use of classic drugs. I also summarize the latest trends of postdischarge nausea and vomiting and the pharmacogenetics, which is attracting a great deal of attention from other medical fields in PONV-related studies. Finally, we discuss the drawbacks of existing studies on PONV and suggest a focus for future investigations. PMID:25302092

    Immunosuppressive therapy is the main postoperative treatment for keratoplasty, but there are considerable differences in protocols for the use of steroids and other immunosuppressants. Therefore, we conducted 2 prospective randomized clinical trials and 1 prospective nonrandomized clinical trial on keratoplasty postoperative treatment. One study evaluated the efficacy and safety of long-term topical corticosteroids after a penetrating keratoplasty was performed. Patients who underwent keratoplasty and maintained graft clarity for >1 year were randomly assigned to either a steroid or a no-steroid group. At the 12-month follow-up, the no-steroid group developed significantly more endothelial rejection than did the steroid group. A second study elucidated the effectiveness and safety of systemic cyclosporine in high-risk corneal transplantation. The patients were assigned to a systemic cyclosporine or control group. At a mean follow-up of 42.7 months, no difference was observed in the endothelial rejection rates and graft clarity loss between the 2 groups. A third study elucidated the effectiveness and the safety of systemic tacrolimus in high-risk corneal transplantation. Of 11 consecutive eyes decompensated despite systemic cyclosporine treatment, there was no irreversible rejection in eyes treated with tacrolimus, which was significantly better than in previous penetrating keratoplasty with systemic cyclosporine treatment. Prognosis after keratoplasty in patients with keratoconus is relatively good, but special attention is required for patients with atopic dermatitis. Postkeratoplasty atopic sclerokeratitis (PKAS) is a severe form of sclerokeratitis after keratoplasty in atopic patients. Our retrospective study showed that 35 eyes of 29 patients from a total of 247 keratoconus eyes undergoing keratoplasty were associated with atopic dermatitis, of which 6 eyes of 5 patients developed PKAS. Eyes with PKAS had a significantly higher incidence of atopic blepharitis

    2002-07-01

    The reason for undertaking this study was that postoperative complications of colic surgery lead to patient discomfort, prolonged hospitalisation and increased cost. Potential risk factors for the 6 most common postoperative complications (jugular thrombosis, ileus, re-laparotomy, wound suppuration, incisional herniation and colic) were evaluated using multivariable models. Jugular thrombosis was associated significantly with heart rate greater than 60 beats/min and with increased packed cell volume (PCV) at admission. The risk of postoperative ileus also increased with increasing PCV at admission and was higher in horses recovering from pedunculated lipoma obstruction. Incisional herniation was strongly associated with wound suppuration and with increasing heart rate at admission. The emergence of cardiovascular parameters as risk factors for several postoperative complications is consistent with the hypothesis that endotoxaemia is important in the development of these complications. Early referral of colic cases, prior to the development of severe endotoxaemic shock, may minimise the risk of some postoperative complications. Horses that have suffered epiploic foramen entrapment, are more than 4 times as likely to undergo re-laparotomy than other horses. Horses that have suffered postoperative ileus have a similarly increased risk of undergoing re-laparotomy. The risk of postoperative colic is significantly associated with horses recovering from large colon torsion (>360 degrees) and with having undergone re-laparotomy. Hazard ratios (with 95% confidence intervals) for these last two effects are 3.1 (1.7, 5.7) and 3.4 (1.9, 6.2), respectively. Knowledge of the risk factors for postoperative complications allows more accurate prognostication postoperatively and suggests ways in which the risk of postoperative complications can be minimised.

    Rationale The current standard surgical treatment for the cervix and uterine cancer is the radical hysterectomy (lymphadenohysterocolpectomy). This has the risk of intraoperative accidents and postoperative associated morbidity. Objective The purpose of this article is the evaluation and quantification of the associated complications in comparison to the postoperative morbidity which resulted after different types of radical hysterectomy. Methods and results Patients were divided according to the type of surgery performed as follows: for cervical cancer – group A- 37 classic radical hysterectomies Class III Piver - Rutledge -Smith ( PRS ), group B -208 modified radical hysterectomies Class II PRS and for uterine cancer- group C -79 extended hysterectomies with pelvic lymphadenectomy from which 17 patients with paraaortic lymphnode biopsy . All patients performed preoperative radiotherapy and 88 of them associated radiosensitization. Discussion Early complications were intra-abdominal bleeding ( 2.7% Class III PRS vs 0.48% Class II PRS), supra-aponeurotic hematoma ( 5.4% III vs 2.4% II) , dynamic ileus (2.7% III vs 0.96% II) and uro - genital fistulas (5.4% III vs 0.96% II).The late complications were the bladder dysfunction (21.6% III vs 16.35% II) , lower limb lymphedema (13.5% III vs 11.5% II), urethral strictures (10.8% III vs 4.8% II) , incisional hernias ( 8.1% III vs 7.2% II), persistent pelvic pain (18.91% III vs 7.7% II), bowel obstruction (5.4% III vs 1.4% II) and deterioration of sexual function (83.3% III vs 53.8% II). PRS class II radical hysterectomy is associated with fewer complications than PRS class III radical hysterectomy , except for the complications of lymphadenectomy . A new method that might reduce these complications is a selective lymphadenectomy represented by sentinel node biopsy . In conclusion PRS class II radical hysterectomy associated with neoadjuvant radiotherapy is a therapeutic option for the incipient stages of cervical cancer

    2015-01-01

    Introduction: In the postoperative phase, the prognosis of multiple trauma patients with severe brain injuries as well as of patients with extensive head and neck surgery mainly depends on protein metabolism and the prevention of septic complications. Wound healing problems can also result in markedly longer stays in the intensive care unit and general wards. As a result, the immunostimulation of patients in the postoperative phase is expected to improve their immunological and overall health. Patients and methods: A study involving 15 patients with extensive ENT tumour surgery and 7 multiple-trauma patients investigated the effect of enteral glutamine supplementation on immune induction, wound healing and length of hospital stay. Half of the patients received a glutamine-supplemented diet. The control group received an isocaloric, isonitrogenous diet. Results: In summary, we found that total lymphocyte counts, the percentage of activated CD4+DR+ T helper lymphocytes, the in-vitro response of lymphocytes to mitogens, as well as IL-2 plasma levels normalised faster in patients who received glutamine-supplemented diets than in patients who received isocaloric, isonitrogenous diets and that these parameters were even above normal by the end of the second postoperative week. Summary: We believe that providing critically ill patients with a demand-oriented immunostimulating diet is fully justified as it reduces septic complications, accelerates wound healing, and shortens the length of ICU (intensive care unit) and general ward stays.

    This paper describes an experimental model of peritoneal adhesions, in the rat, based on two relatively minor accidents that may occur during abdominal surgery in man: drying of the serosa, and bleeding. Drying alone had little effect; drying plus bleeding consistently produced adhesions to the dried area. Fresh blood alone produced adhesions between the three membranous structures [omentum and pelvic fat bodies (PFBs)]. The formation of persistent adhesions required whole blood. Preformed clots above a critical size induced adhesions even without previous serosal injury; they were usually captured by the omentum and PFBs. If all three membranous structures were excised, the clots caused visceral adhesions. The protective role of the omentum, its structure, and the mechanism of omental adhesions, are discussed. These findings are relevant to the pathogenesis of post-operative adhesions in man. ImagesFig 3Fig 4Fig 5Fig 6Fig 7Fig 12Fig 13Fig 1Fig 2Fig 14Fig 15Fig 8Fig 9Fig 10Fig 11 PMID:5315369

    Postoperative chronic subdural hematoma (CSH) following craniotomy developed in only four of 372 patients undergoing craniotomy for aneurysm surgery (1 patient) and brain tumor surgery (3 patients) between April, 1991 and November, 1993, an incidence of only 1.1%. There were three males and one female, aged from 32 to 66 years (mean 56 yrs). The period between craniotomy and development of CSH ranged from 3 to 5 months (mean 4.3 mos). Postoperative hematomas were located on the operative sides in three patients and the contralateral side in the other. Early postoperative computed tomographic scans found subdural fluid collection in all patients. Magnetic resonance images showed linear meningeal enhancement in all patients. Postoperative CSH may be caused by mixture of blood in subdural cerebrospinal fluid collection which persists due to reduced brain elasticity and wide subarachnoid membrane opening resulting in neomembrane formation and finally development of hematoma.

    Objective: The aims of this study were to evaluate serum levels of acute phase reactants, such as CRP and cytokines (TNF-α and IL-6) in patients who have undergone thoracotomy and to investigate the effects of flurbiprofen on postoperative inflammatory response. Methods: Forty patients undergoing posterolateral thoracotomy were randomly divided into 2 groups of 20 each. Control group received tramadol (4 x 100 mg) intravenously for four days, and flurbiprofen group received both tramadol (4 x 100 mg) and flurbiprofen (2 x 100 mg). Blood samples were collected before surgery and at the 3th and 168th hours after surgical procedure to measure serum CRP, IL-6, and TNF-α. Pain visual analog scales were recorded daily during the first four postoperative days. Spirometric measurement of forced expiratory volume in the first second (FEV 1) was done before and four days after the operation. Results: The serum CRP, IL-6, and TNF-α levels in both groups increased significantly at 3th hour after thoracotomy. Serum TNF-α levels did not differ significantly between the groups at postoperative 4th day. However, IL-6 and CRP were significantly lower in flurbiprofen group than in control group at the same day (p<0.05). Visual analog scale was significantly lower in flurbiprofen group at 6th, 12th, 48th, 72th, and 96th hours postoperatively (p<0.05). The patients receiving flurbiprofen had higher FEV 1 values when compared with control group at postoperative 4th day. Conclusions: Patients undergoing thoracotomy showed reduced postoperative pain, mean additional analgesic consumption, and serum IL-6 and CRP levels, when flurbiprofen was added to systemic analgesic therapy. Analgesia with anti-inflammatory drug may contribute to the attenuation of the postoperative inflammatory response and prevent postoperative pain in patients undergoing thoracotomy. PMID:21448308

    Congenital cataract is a common cause of childhood low vision or blindness worldwide. Early surgery should be performed in sensitive vision development period to avoid vision deprivation in cases of strabismus and nystagmus development. Postoperative recovery of visual function is of great significance for these patients and should include proper postoperative aphakia correction by the application of a contact lens and secondary implantation of an intraocular lens (IOL). Patients should receive amblyopic training after surgery to improve their postoperative visual acuity. Although recent advances in surgery techniques and materials have brought better postoperative visual acuity and less complications, a few postoperative complications can still hamper vision condition and vision development, including posterior capsule opacification and secondary glaucoma. Surgery in early infancy are risk factors for these two complications. Life-long follow-up is essential for these patients. Further study will continue to address the surgery timing issue and methods that prevent postoperative complications. PMID:26390798

    Background Liver graft dysfunction can deteriorate to complete organ failure and increases perioperative morbidity and mortality after liver transplantation. Therapeutic strategies reducing the rate of graft dysfunction are of current clinical relevance. One approach is the systemic application of prostaglandins, which were demonstrated to be beneficial in reducing ischemia-reperfusion injury. Preliminary data indicate a positive effect of prostacyclin analogue iloprost on allograft viability after liver transplantation. The objective of the study is to evaluate the impact of iloprost in a multi-center trial. Methods/Design A prospective, double-blinded, randomized, placebo-controlled multicenter study in a total of 365 liver transplant recipients was designed to assess the effect of intravenous iloprost after liver transplantation. Primary endpoint will be the primary graft dysfunction characterized as presentation of one or more of the following criteria: ALAT or ASAT level > 2000 IU/ml within the first 7 postoperative days, bilirubine ≥ 10 mg/dl on postoperative day 7; INR ≥ 1.6 on postoperative day 7 or initial non-function. Secondary endpoints are parameters of post-transplant morbidity, like rates of infections, biliary complications, need of clotting factors or renal replacement therapy and the graft and patient survival. Discussion A well-established treatment concept to avoid graft dysfunction after liver transplantation does not exist at the moment. If the data of this research project confirm prior findings, iloprost would improve the general outcome after liver transplantation. Trial Registration German Clinical Trials Register: DRKS00003514.

    Introduction: Several studies have found anesthetic agents including propofol in ovarian follicular fluid. However, little is known about the effect of anesthetic agents on ovarian function. We aimed to investigate whether there were differences in the postoperative levels of sex hormones when propofol was used as the anesthetic agent. Methods: A retrospective review was done of 80 patients who underwent ovarian surgery, with 72 infertile women serving as controls. Patients were included in the study if their serum estradiol (E2) and follicle stimulating hormone (FSH) levels were measured during their first postoperative menstrual cycle. Results: Patients were grouped according to the use or non-use of propofol as follows: propofol group (n = 39) and non-propofol group (n = 41). The control group did not undergo surgery. Postoperative E2 levels did not differ between the three groups, but FSH levels were significantly higher in the patients who had undergone surgery compared to controls (p < 0.05). Post-hoc analysis of E2 and FSH levels in the propofol and non-propofol groups did not show any significant differences. Conclusions: The use of propofol did not result in any differences compared to other anesthetic agents in terms of postoperative sex hormone levels after gynecologic surgery. The type of anesthetic agent does not seem to affect the postoperative levels of female sex hormones. PMID:27134297

    Krebs von den Lungen-6 (KL-6) is a high-molecular-weight glycoprotein which is elevated in serum of patients with interstitial pneumonia (IP). Serum KL-6 level is clinically used for the diagnosis of IP as well as the evaluation of its disease activity. KL-6 is originally identified when exploring novel soluble antigens in patients with lung cancer, and is known to be elevated in patients with several malignant tumors. The risk of malignant tumors is high in IP patients with polymyositis and dermatomyositis (PM/DM), and follow-up of KL-6 levels may allow earlier detection of such tumors. However, to date, there are only a few reports showing the usefulness of following-up serum KL-6 levels for finding malignant tumors in IP patients with PM/DM. Here, we described the first patient in whom increased serum KL-6 led to the diagnosis of colon cancer during follow-up of DM-associated IP.

    Postoperative follow-up of glaucoma surgery must be rigorous and carried out over the long term. Data acquired on the make-up of the filtering bleb justifies using postoperative anti-inflammatory drugs, even if the eye is clinically quiet. When using antimetabolites, the risk factors for failure must be well known and either 5-fluorouracile or mitomycin should be chosen depending on the level of risk of scarring. Their use in needle revision must be adapted case by case. anti-TGF-beta-2 antibody, currently being investigated, may prove advantageous in the very near future. PMID:16208245

    Purpose To analyze the risk factors for postoperative lymphocele, for predicting and preventing complications. Methods We evaluated 92 kidney transplant recipients with multidetector CT (MDCT) at 1-month posttransplantation. From admission and 1-month postoperative records, data including diabetes, dialysis type, immunosuppressant use, steroid pulse therapy, and transplantation side were collected. Lymphocele volume was measured with 3-dimensional reconstructed, nonenhanced MDCT at one month postoperatively. The correlations between risk factors and lymphocele volume and between risk factors and symptomatic lymphocele (SyL) were analyzed. The cutoff was calculated by using the receiver operating characteristic (ROC) curve for SyL volume. Results Among 92 recipients, the mean volume was 44.53 ± 176.43 cm3 and 12 had SyL. Univariable analysis between risk factors and lymphocele volume indicated that donor age, retransplantation, and inferiorly located lymphocele were statistically significant. The ROC curve for SyL showed that 33.20 cm3 was the cutoff, with 83.3% sensitivity and 93.7% specificity. On univariable analysis between risk factors and SyL, steroid pulse, inferiorly located lymphocele, and >33.20 cm3 were statistically significant. Multivariable analysis indicated that steroid pulse, >33.20 cm3, and serum creatinine level at one month were significant factors. Conclusion Risk factors including donor age, retransplantation, steroid pulse therapy, and inferiorly located lymphocele are important predictors of large lymphoceles or SyL. In high-risk recipients, careful monitoring of renal function and early image surveillance such as CT or ultrasound are recommended. If the asymptomatic lymphocele is >33.20 cm3 or located inferiorly, early interventions can be considered while carefully observing the changes in symptoms. PMID:27617254

    Rheumatoid arthritis is often accompanied by massive destruction of the smaller and larger joints even with early therapy using antirheumatic drugs. In these cases total joint arthroplasty is the only surgical option, especially for the knee and hip joint. Knowledge of the specific disease-related postoperative characteristics is a prerequisite for the successful treatment of patients with rheumatoid arthritis. As dislocation of the arthroplastic joint does not occur more often in rheumatoid arthritis, the risk of periprosthetic infection is increased due to the use of biologicals. Therefore, a perioperative optimization is obligatory. In order to facilitate independence in daily living physiotherapy in combination with aids such as arthritis crutches, gripping pliers or raised toilet seat need to be started as soon as possible after surgical treatment. To achieve this goal it is recommended to refer patients with inflammatory arthritis to inpatient rehabilitation facilities. With respect to the specific postoperative treatment after joint replacement the long-term results are comparable with those from patients with primary osteoarthritis.

    OBJECTIVE: This study was performed to assess the prognostic value of serum beta human chorionic gonadotropin (βhCG), measured on day 14 post embryo transfer (ET) for predicting multiple gestation and pregnancy wastage in women undergoing in vitro fertilization ET (IVF-ET). MATERIALS AND METHODS: This retrospective study was performed between May 2009 and November 2012. Out of the 181 women who conceived, 168 were included and the remaining 13 were excluded as their pregnancy was biochemical. Serum βhCG was measured using a chemiluminescent enzyme immunometric assay. The predictive values of serum βhCG for establishing multiple pregnancy and pregnancy wastages were calculated by receiver operating characteristic (ROC) curve analysis. Median values of serum βhCG and outcome of all pregnancies were compared. RESULTS: Out of the 168 patients who conceived after IVF treatment, 114 (68%) were viable pregnancies (delivered/ongoing). Among the viable pregnancies, 97 (85%) had a successful pregnancy outcome and the remaining 17 patients are ongoing pregnancies. Median values of βhCG (625 IU/L) among viable pregnancies was significantly (P < 0.05) higher than that of nonviable pregnancies (174 IU/L). The median values of βhCG for singleton (502 IU/L), twins (1093 IU/L), and triplets (2160 IU/L) was statistically significant (P < 0.05). Using ROC curve it was predicted that for a value of βhCG at 375 IU/L, the sensitivity of viable pregnancy was 65% and specificity of viable pregnancy was also 65%, with positive and negative predictive values of 65 and 68%, respectively. Similarly for multiple pregnancy and pregnancy wastage the predictive values of βhCG were 808 and 375 IU/L, respectively; while the sensitivity and specificity is more than 65% each. CONCLUSION: βhCG cutoff values determined on day 14 post ET by ROC curve analysis are useful in discriminating between multiple pregnancy and pregnancy losses. The cutoff value might aid in the prognosis, clinical

    Mesocestoides corti is a suitable in vitro model for studying the development of human endoparasitic platyhelminthes. Treatment with trypsin, supplemented with fetal bovine serum (FBS), induces M. corti development from larvae (tetrathyridia) to segmented adult worm; however, the role of this protease and of FBS in post-larval development induction remains unknown. To characterize the participation of trypsin enzymatic activity and of FBS in the induction of tetrathyridia growth and development, both stimuli were added to the larvae either together or sequentially. Additionally, specific inhibition of trypsin activity was also monitored. Finally, the effect of the enzyme on the parasite tegument as well as the proliferative activity and location of proliferating cells after induction of tetrathyridia development were also studied. We conclude that trypsin-induced tetrathyridia development to adult worm is FBS-dependent and that the effect of serum factors is dependent upon a previous trypsin-induced reversible damage to the larva tegument. In dividing and non-dividing tetrathyridia, proliferative activity of cells is mainly located within the apical massif in the anterior region and nerve cords of larvae, respectively. In tetrathyridia stimulated to develop to adult worms, an intense proliferative activity is evident along the nerve cords. Our results suggest that in natural infections the tetrathyridia tegument is temporally made permeable to growth factors by proteolytic enzyme activity in the intestine juice of the definitive host, thus leading to development to adult worms.

    Computed tomography (CT) of the abdomen was performed on 46 patients who had undergone graft replacement of abdominal aortic aneurysms. Twelve post-operative complications were found in nine patients. They included hemorrhage, infection, anastomotic pseudoaneurysms, major vessel occlusion, postoperative pancreatitis, and others. The varied apperance of the normal postoperative graft is also presented. It is concluded that CT is a rapid, sensitive, and noninvasive method for detecting or excluding postoperative complications of abdominal aortic surgery.

    From 1984-1990, 52 patients with pituitary adenomas had postoperative radiosurgery for incomplete surgical removal or regrowth of the tumor. The atraumatic Greitz-Bergström fixation head device was adopted for the stereotactic procedure and irradiation was performed with a linear accelerator. Because of the variability of the tumor response, a 10-20 Gy single dose was directed at 1-2 targets and radiosurgery repeated if the result was unsatisfactory. The median radiation dose was 30 Gy. No adverse effects occurred. Regression of pretreatment symptoms caused by tumor mass was observed in 67% of patients. GH and PRL activity decreased in 20 patients, was stable in 11 and increased in 2 prolactinomas. CT studies showed disappearance of the tumor in 4 patients and shrinkage in 36. Postoperative radiosurgery is a valuable method of treatment whenever pituitary surgery has been incomplete.

    BACKGROUND Based on our laboratory work and clinical trials we hypothesised that radiotherapy after lumpectomy for breast cancer could be restricted to the tumour bed. In collaboration with the industry we developed a new radiotherapy device and a new surgical operation for delivering single-dose radiation to the tumour bed - the tissues at highest risk of local recurrence. We named it TARGeted Intraoperative radioTherapy (TARGIT). From 1998 we confirmed its feasibility and safety in pilot studies. OBJECTIVE To compare TARGIT within a risk-adapted approach with whole-breast external beam radiotherapy (EBRT) over several weeks. DESIGN The TARGeted Intraoperative radioTherapy Alone (TARGIT-A) trial was a pragmatic, prospective, international, multicentre, non-inferiority, non-blinded, randomised (1 : 1 ratio) clinical trial. Originally, randomisation occurred before initial lumpectomy (prepathology) and, if allocated TARGIT, the patient received it during the lumpectomy. Subsequently, the postpathology stratum was added in which randomisation occurred after initial lumpectomy, allowing potentially easier logistics and a more stringent case selection, but which needed a reoperation to reopen the wound to give TARGIT as a delayed procedure. The risk-adapted approach meant that, in the experimental arm, if pre-specified unsuspected adverse factors were found postoperatively after receiving TARGIT, EBRT was recommended. Pragmatically, this reflected how TARGIT would be practised in the real world. SETTING Thirty-three centres in 11 countries. PARTICIPANTS Women who were aged ≥ 45 years with unifocal invasive ductal carcinoma preferably ≤ 3.5 cm in size. INTERVENTIONS TARGIT within a risk-adapted approach and whole-breast EBRT.

    Purpose This study aimed to examine extended postoperative ileus and its risk factors in patients who have undergone abdominal surgery, and discuss the techniques of prevention and management thereof the light of related risk factors connected with our study. Methods This prospective study involved 103 patients who had undergone abdominal surgery. The effects of age, gender, diagnosis, surgical operation conducted, excessive small intestine manipulation, opioid analgesic usage time, and systemic inflammation on the time required for the restoration of intestinal motility were investigated. The parameters were investigated prospectively. Results Regarding the factors that affected the restoration of gastrointestinal motility, resection operation type, longer operation period, longer opioid analgesics use period, longer nasogastric catheter use period, and the presence of systemic inflammation were shown to retard bowel motility for 3 days or more. Conclusion Our study confirmed that unnecessary analgesics use in patients with pain tolerance with non-steroid anti-inflammatory drugs, excessive small bowel manipulation, prolonged nasogastric catheter use have a direct negative effect on gastrointestinal motility. Considering that an exact treatment for postoperative ileus has not yet been established, and in light of the risk factors mentioned above, we regard that prevention of postoperative ileus is the most effective way of coping with intestinal dysmotility.

    Pancreas grafts are susceptible to surgical complications mostly related to exocrine secretions and the low microcirculatory blood flow through the gland. During simultaneous kidney-pancreas transplantation, the systemic response depends on reperfusion of two organs acute graft pancreatitis, immunotherapy, coagulopathy, bleeding, and other factors. We performed a retrospective review of 10 adult simultaneous pancreas-kidney transplant patients to evaluate progression of early postoperative inflammation in the absence of infection. All patients were treated with four-drug therapy. We performed analyses of procalcitonin (PCT), C-reactive protein, serum creatinine, amylase, and lipase levels over the first 5 postoperative days. Relatively high peak PCT levels (maximum 130 ng/mL) were reached within 24 to 48 hours postoperatively followed by a moderate decrease. Consistent with this observation, the serum creatinine, amylase, and lipase levels decreased continuously to normal concentrations within the first week. The increased PCT levels seemed depend upon the surgical procedure and intraoperative events. PCT was superior to C-reactive protein to discriminate infection from inflammation in this setting. The dynamics of PCT levels, rather than absolute values, seemed to be important. Lack of a decrease in PCT levels after the peak, suggested an infectious complication or the development of sepsis. Monitoring and assessment of PCT levels may help in early recognition of infection and institution of therapy.

    Mycobacterium avium subspecies paratuberculosis (MAP) is the aetiological agent of Johne’s disease (JD), a chronic enteritis in ruminants that causes substantial economic loses to agriculture worldwide. Current diagnostic assays are hampered by low sensitivity and specificity that seriously complicate disease control; a new generation of diagnostic and prognostic assays are therefore urgently needed. Circulating microRNAs (miRNAs) have been shown to have significant potential as novel biomarkers for a range of human diseases, but their potential application in the veterinary sphere has been less well characterised. The aim of this study was therefore to apply RNA-sequencing approaches to serum from an experimental JD infection model as a route to identify novel diagnostic and prognostic miRNA biomarkers. Sera from experimental MAP-challenged calves (n = 6) and age-matched controls (n = 6) were used. We identified a subset of known miRNAs from bovine serum across all samples, with approximately 90 being at potentially functional abundance levels. The majority of known bovine miRNAs displayed multiple isomiRs that differed from the canonical sequences. Thirty novel miRNAs were identified after filtering and were found within sera from all animals tested. No significant differential miRNA expression was detected when comparing sera from MAP-challenged animals to their age-matched controls at six-month’s post-infection. However, comparing sera from pre-infection bleeds to six-month’s post-infection across all 12 animals did identify increased miR-205 (2-fold) and decreased miR-432 (2-fold) within both challenged and control groups, which suggests changes in circulating miRNA profiles due to ageing or development (P<0.00001). In conclusion our study has identified a range of novel miRNA in bovine serum, and shown the utility of small RNA sequencing approaches to explore the potential of miRNA as novel biomarkers for infectious disease in cattle.

    The present study examines the reasons cited by 103 patients for their electing to undergo total knee arthroplastic surgery and the relationship between these reasons and their post-operative pain and range of motion. Results suggest that individuals who describe different reasons for undergoing surgery vary in their post-operative recovery. Specifically, patients who cite pain as the reason they are undergoing surgery report greater levels of pain during the early post-operative period. In contrast, patients who describe goals of regaining mobility or a specific activity as their reason for undergoing surgery achieve a greater range of motion during early post-operative physical therapy. Individuals who express avoidance goals for undergoing total knee arthroplasty report more severe post-operative pain at 1 and 3 months following surgery compared to patients who express approach goals. Interventions targeted towards patients reporting pre-operative pain or avoidance goals may decrease subsequent post-operative pain and increase mobility.

    OBJECTIVE: The authors set out to determine whether immediate enteral feeding minimizes early postoperative decreases in handgrip and respiratory muscle strength. SUMMARY BACKGROUND DATA: Muscle strength decreases considerably after major surgical procedures. Enteral feeding has been shown to restore strength rapidly in other clinical settings. METHODS: A randomized, controlled, nonblinded clinical trial was conducted in patients undergoing esophagectomy or pancreatoduodenectomy who received immediate postoperative enteral feeding via jejunostomy (fed, n = 13), or no enteral feeding during the first 6 postoperative days (unfed, n = 15). Handgrip strength, vital capacity, forced expiratory volume in one second (FEV1), and maximal inspiratory pressure (MIP) were measured before surgery and on postoperative days 2, 4, and 6. Fatigue and vigor were evaluated before surgery and on postoperative day 6. Mobility was assessed daily after surgery using a standardized descriptive scale. Postoperative urine biochemistry was evaluated in daily 24-hour collections. RESULTS: Postoperative vital capacity (p < 0.05) and FEV1 (p = 0.07) were consistently lower (18%-29%) in the fed group than in the unfed group, whereas grip strength and maximal inspiratory pressure were not significantly different. Postoperative mobility also was lower in the fed patients (p < 0.05) and tended to recover less rapidly (p = 0.07). Fatigue increased and vigor decreased after surgery (both p < or = 0.001), but changes were similar in the fed and unfed groups. Intensive care unit and postoperative hospital stay did not differ between groups. CONCLUSIONS: Immediate postoperative jejunal feeding was associated with impaired respiratory mechanics and postoperative mobility and did not influence the loss of muscle strength or the increase in fatigue, which occurred after major surgery. Immediate postoperative enteral feeding should not be routine in well-nourished patients at low risk of nutrition

  12. Difficulties in diagnosing acute kidney injury post liver transplantation using serum creatinine based diagnostic criteria

    Renal function in patients with advanced cirrhosis is an important prognostic factor for survival both prior to and following liver transplantation. The importance of renal function is reflected by the introduction of the model for end stage liver disease (MELD) score, which includes serum creatinine. The MELD score has been shown to predict the short term risk of death for transplant wait listed patients and is currently used by many countries to allocate liver transplants on the basis of severity of underlying illness. Changes in serum creatinine are also used to stage acute kidney injury. However prior to liver transplantation the serum creatinine typically over estimates underlying renal function, particularly when a colorimetric Jaffe based assay is used, and paradoxically then under estimates renal function post liver transplantation, particularly when immunophyllins are started early as part of transplant immunosuppression. As acute kidney injury is defined by changes in serum creatinine, this potentially leads to over estimation of the incidence and severity of acute kidney injury in the immediate post-operative period.

    The purpose of this study was to evaluate the effectiveness of combined surgical and medical treatment of infective endocarditis in patients with congenital valvular heart disease when included in a regimen of the drug Reamberin. In this regard, the analysis of the effectiveness of a combination regimen of 74 patients with valvular congenital heart diseases complicated with infective endocarditis. Given the indications for surgical correction operative technique features and possible technical difficulties in carrying out such operations, due to the inflammatory changes and tissue destruction, and ways to overcome them. For the correction of metabolic disorders in the postoperative period, 47 patients (main group) was appointed Reamberin: once, intravenous drip 400 ml/day during the first 5 days after surgery. 27 patients (control group) was conducted infusion therapy depending on the severity of the condition according to the classical scheme. In addition to standard clinical and laboratory examination, to assess the effectiveness of Reamberin was investigated catalase activity of CPK in blood serum in the dynamics of observation (1, 3 and 5 days after surgery). It is revealed that surgical approach, used in complex treatment of patients with valvular congenital heart diseases, including reorganization of the cavities of the heart, increasing the frequency of joints and the use of reinforcing strips of synthetic material that prevents the cutting of sutures through the inflamed tissue has achieved good short-and long-term results. Infective endocarditis and destruction of the valvular annulus fibrosus the use of a frame of strips of polytetrafluoroethylene allows you to restore its integrity and to implant a mechanical prosthesis. The inclusion in the regimen of patients with infective endocarditis complicated by cardiac insufficiency in the early postoperative period the drug Reamberin improves the efficiency of treatment by a more rapid restoration of the normal

    The phenomenon of delirium is well known since over 100 years. The anesthesiology has recognized that early detection and therapy results in significant improvement of postoperative clinical state of health of the patients. In the following article it will be discussed that it could be profitable to make a further step: threatening the subsyndromal delirium. Because there are only few experiences in anesthesiology, this thesis will be substantiated by datas from psychiatry.

    Bacterial infections are the most common complications, and the major cause of mortality after liver transplantation (Tx). Neopterin, a marker of immune activation, is produced in monocyte/macrophages in response to inflammation. The aim of our study was to investigate whether early post-operation serum levels of neopterin were associated with post-transplant bacteremia and mortality in liver transplant recipients. We studied 162 of 262 liver Tx patients between January 2008 and February 2011 of whom pre- and early post-Tx sera samples were available. Pre- and early post-operative risk factors of infection and mortality were evaluated in 45 bacteremic patients and 117 non-bacteremic patients. During one-year follow-up, 28 of 262 patients died because of graft failure, septicemia and other diseases. Post-Tx serum neopterin on day 10 (p<0.001) were significantly higher in bacteriemic patients than in patients without bacteremia. Logistic regression analyses showed that day 10 post-Tx neopterin serum level ⩾40 nmol/l has a predictive value (OR=6.86: p<0.001) for bacteremia and mortality (OR=3.47: p=0.021). Our results suggest that early post-Tx neopterin serum levels are very sensitive predictive markers of one-year post-Tx bacteremia and mortality in liver Tx recipients.

    Study Design Retrospective study. Purpose The aim of the study was to study the impact and outcome of conservative management and surgical intervention in cases of postoperative discitis. Overview of Literature Postoperative discitis is a rare but often misdiagnosed cause of failed back syndrome. There is paucity of literature regarding management guidelines of postoperative discitis. Methods The study was carried out over a period of 6 years. Eighteen patients with postoperative discitis were included in the study. Results Conservative management with antibiotics, analgesics and bed rest were started in all the study cases. Posterior transpedicular fixation after re-exploration debridement and curettage of disc space granulation tissue was conducted in five patients in whom conservative management failed. Conclusions Early diagnosis and appropriate management is the key to effective treatment of postoperative discitis. Conservative management leads to excellent results in majority of cases. Surgical intervention with posterior interbody fusion and debridement is helpful when conservative treatment fails. PMID:26240715

    Experiments on the model of mouse BCG-induced granulomatous showed that the content of glycosaminoglycans and proteoglycans in the extracellular matrix of the liver and lungs are changed at the early stages of inflammation (days 3 and 30 postinfection) before cell destruction in the organs begins. This is related to degradation of extracellular matrix structures. Their high content in the blood and interstitium probably contributes to the formation of granulomas, fibroblast proliferation and organ fibrosis. These processes depend on the infection route that determines different conditions for generalization of the inflammation process. Intravenous method of vaccine injection is preferable to use when designing the experiments simulating tuberculosis granulomatosis, especially for the analysis of its early stages. PMID:25573360

    In a randomized double-blind study of thirty grossly obese patients undergoing gastroplasty for weight reduction, the effects of intramuscular and epidural morphine were compared as regards analgesia, ambulation, gastrointestinal motility, early and late pulmonary function, duration of hospitalization, and occurrence of deep vein thrombosis in the postoperative period. The patients were operated on under thoracic epidural block combined with light endotracheal anesthesia. A six-grade scale was devised to quantify postoperative mobilization. A radioactive isotope method using 99mTc -plasmin was employed to detect postoperative deep vein thrombosis. For 14 hr after the first analgesic injection, respiratory frequency was noted every 15 min and arterial blood gases were measured hourly. Peak expiratory flow was recorded daily until the patient was discharged from hospital. Spirometry was performed the day before and the day after surgery. Plasma concentrations of morphine were measured after both intramuscular and epidural administration. Both intramuscular and epidural morphine gave effective analgesia, but the average dose of intramuscular morphine was up to seven times greater than that required by the epidural route. A larger number of patients receiving epidural morphine postoperatively were able to sit, stand, or walk unassisted within 6, 12, and 24 hr, respectively. Being alert and more mobile as a result of superior postoperative analgesia from epidural morphine, patients in this group benefited more from vigorous physiotherapy routine, which resulted in fewer pulmonary complications. Furthermore, earlier postoperative recovery of peak expiratory flow and bowel function presumably contributed to a significantly shorter hospitalization in patients receiving epidural morphine. There was no evidence of prolonged respiratory depression in this high-risk category of patients. The 99mTc -plasmin tests revealed no significant difference between the two groups.

    Objective: Adiponectin and high-sensitivity C-reactive protein (hsCRP) can be used as early biochemical markers of cardiovascular diseases (CVDs). Radiologically, non-invasive flow-mediated dilation (FMD) of the brachial artery and carotid intima-media thickness (CIMT) measurements may be used as indicators in the early diagnosis of CVDs. To compare the biochemical markers of atherosclerosis with radiological markers of CVDs (CIMT, FMD, ventricular systolic and diastolic functions) and to assess the relationship of these parameters with metabolic control in diabetic children and adolescents. Methods: A total of 55 patients with type 1 diabetes mellitus (T1DM) of at least 5-year duration and 30 healthy subjects were included in the study. Serum adiponectin, hsCRP, hemoglobin A1c (HbA1c), and lipid levels were evaluated in the patients and in the controls. CIMT, FMD, ventricular systolic and diastolic functions were assessed by echocardiography. Results: Mean age of the patients with diabetes was 17.6 years; mean diabetes duration was 10.4 years. Mean serum hsCRP was elevated in children with diabetes (0.21±0.31 vs. 0.10±0.16 μg/mL, p=0.00), while no significant difference from the controls was found in adiponectin levels. Mean CIMT was significantly higher in diabetic children compared to the control group (0.53±0.11 vs. 0.34±0.46 mm, p=0.00). Mean FMD of the diabetic children was significantly lower than that of the controls (6.86±2.85% vs. 12.13±1.99%, p=0.00). Diabetes duration was positively correlated with CIMT and negatively correlated with FMD. Right ventricular (RV) and left ventricular (LV) myocardial performance index (MPI) were higher in the patient group (p=0.00). Conclusions: Our data suggest that in addition to standard echocardiography, tissue Doppler echocardiography, FMD, and CIMT can be used as early-stage radiological markers and hsCRP as an early-stage biochemical marker of atherosclerosis in the routine follow-up of T1DM patients

    Dietary lutein intake is postulated to interfere with the development of age-related macular degeneration (AMD). Because egg yolk-derived lutein has a high bioavailability, long-term consumption of lutein-enriched eggs might be effective in preventing AMD development, but alternatively might increase cardiovascular disease risk. Here, we report the effect of 1-y daily consumption of a buttermilk drink containing 1.5 lutein-rich egg yolks on serum lipid and lipoprotein and plasma lutein concentrations. Additionally, subgroups that could potentially benefit the most from the intervention were identified. Men and women who had early signs of AMD in at least 1 eye, but were otherwise healthy, participated in a 1-y randomized, placebo-controlled parallel intervention trial. At the start of the study, 101 participants were included: 52 in the experimental (Egg) group and 49 in the control (Con) group. Final analyses were performed with 45 participants in the Egg group and 43 participants in the Con group. As expected, the increase in plasma lutein concentrations in the Egg group was 83% higher than that in the Con group (P < 0.001). Changes in serum total, HDL, and LDL cholesterol, as well as the ratio of total cholesterol to HDL cholesterol, were not different between the 2 groups. Interestingly, participants classified as cholesterol absorbers had higher serum HDL cholesterol concentrations than participants classified as cholesterol synthesizers or participants with average campesterol-to-lathosterol ratios (P < 0.05) at baseline. In addition, cholesterol absorbers had a 229% higher increase in plasma lutein concentrations than participants who were classified as having an average campesterol-to-lathosterol ratio upon consumption of the lutein-enriched egg yolk drink (P < 0.05). Moreover, the change in serum HDL cholesterol upon consumption was significantly different between these 3 groups (P < 0.05). We suggest that cholesterol absorbers particularly might benefit

    Pain after an open inguinal hernia repair may be significant. In fact, some surgeons feel that the pain after open repair justifies a laparoscopic approach. The purpose of this study was to determine if the use of local anesthetic infusion pumps would reduce postoperative pain after open inguinal hernia repair. We performed a prospective, double-blind randomized study of 45 open plug and patch inguinal hernia repairs. Patients were randomized to receive either 0.25 per cent bupivicaine or saline solution via an elastomeric infusion pump (ON-Q) for 48 hours, at 2 cc/h. The catheters were placed in the subcutaneous tissue and removed on postoperative day 3. Both groups were prescribed hydrocodone to use in the postoperative period at the prescribed dosage as needed for pain. Interviews were conducted on postoperative days 3 and 7, and patient's questionnaires, including pain scores, amount of pain medicine used, and any complications, were collected accordingly. During the first 5 postoperative days, postoperative pain was assessed using a visual analog scale. Twenty-three repairs were randomized to the bupivicaine group and 22 repairs randomized to the placebo group. In the bupivicaine group, there was a significant decrease in postoperative pain on postoperative days 2 through 5 with P values <0.05. This significant difference continued through postoperative day 5, 2 days after the infusion pumps were removed. Patients who had bupivicaine instilled in their infusion pump had statistically significant lower subjective pain scores on postoperative days 2 through 5. This significant difference continued even after the infusion pumps were removed. Local anesthetic infusion pumps significantly decreased the amount of early postoperative pain. Pain relief persisted for 2 days after catheter and pump removal. PMID:15586515

    A 55-year-old man suffered from blurred vision of the left eye (visual acuity was counting fingers/5-10 cm) 8 days after undergoing cataract surgery. After thorough ophthalmologic examinations with gram-negative bacillus justified on smear of vitreous specimen, postoperative endophthalmitis (os) was impressed. Intravitreous injection of 1.0 mg of vancomycin, 0.4 mg of amikacin, and 0.4 mg of dexamethasone was given twice and vitreous fluid culture was also performed. However, the inflammatory condition was not well controlled. Because the results of vitreous fluid culture revealed Flavimonas oryzihabitans infection which is sensitive to piperacillin, we performed the 3rd intravitreous injection of 1.0 mg of piperacillin and 0.4 mg of dexamethasone. The inflammatory condition was under control and the visual acuity of left eye improved. For patients with ocular diseases, postoperative endophthalmitis by Flavimonas oryzihabitans is a rare condition. According to the results of this case, intravitreous injection of piperacillin was effective against the pathogen.

    Introduction: Complications within laparoscopic surgery, similar to classic surgery are inevitable and require immediate actions both to diminish intraoperative risks and to choose the appropriate therapeutic attitude. Peritonitis and hemorrhagic incidents are both part of the complications aspect of laparoscopic surgery. Fortunately, the incidence is limited, thus excluding the rejection of celioscopic methods. Patient’s risks and benefits are to be analyzed carefully prior recommending laparoscopic surgery. Materials and methods: This study presents a statistical analysis of peritonitis consecutive to laparoscopic surgery, experience of „Sf. Ioan” Emergency Hospital, Bucharest, and Department of Surgery (2000-2010). Results:There were 180 (0,96%) complicated situations requiring reinterventions, from a total of 18676 laparoscopic procedures. 106 cases (0,56%) represented different grades of postoperative peritonitis. Most frequently, there were consecutive laparoscopic appendicectomia and colecistectomia. During the last decade, few severe cases of peritonitis followed laparoscopic bariatric surgical procedures. Conclusions: This study reflects the possibility of unfavorable evolution of postoperative peritonitis comparing with hemorrhagic incidents within laparoscopic surgery. PMID:23049630

    Immunogenicity assessment during early stages of nonclinical biotherapeutic development is not always warranted. It is rarely predictive for clinical studies and evidence for the presence of anti-drug antibodies (ADAs) may be inferred from the pharmacokinetic (PK) profile. However, collecting and banking samples during the course of the study are prudent for confirmation and a deeper understanding of the impact on PK and safety. Biotherapeutic-specific ADA assays commonly developed can require considerable time and resources. In addition, the ADA assay may not be ready when needed if the study of PK and safety data triggers assay development. During early stages of drug development for antibody-drug conjugates (ADCs), there is the added complication of the potential inclusion of several molecular variants in a study, differing in the linker and/or drug components. To simplify analysis of ADAs at this stage, we developed plug-and-play generic approaches for both the assay format and the data analysis steps. Firstly, the assay format uses generic reagents to detect ADAs. Secondly, we propose a cut point methodology based on animal specific baseline variability instead of a population data approach. This assay showed good sensitivity, drug tolerance, and reproducibility across a variety of antibody-derived biotherapeutics without the need for optimization across molecules. PMID:27092313

    OBJECTIVE: To evaluate the safety and efficacy of early rehabilitation after surgery program (ERAS) in patients undergoing laparoscopic assisted total gastrectomy. MATERIALS AND METHODS: This is a study where 47 patients who are undergoing lap assisted total gastrectomy are selected. Twenty-two (n = 22) patients received enhanced recovery programme (ERAS) management and rest twenty-five (n = 25) conventional management during the perioperative period. The length of postoperative hospital stay, time to passage of first flatus, intraoperative and postoperative complications, readmission rate and 30 day mortality is compared. Serum levels of C-reactive protein pre-operatively and also on post-op day 1 and 3 are compared. RESULTS: Postoperative hospital stay is shorter in ERAS group (78 ± 26 h) when compared to conventional group (140 ± 28 h). ERAS group passed flatus earlier than conventional group (37 ± 9 h vs. 74 ± 16 h). There is no significant difference in complications between the two groups. Serum levels of CRP are significantly low in ERAS group in comparison to conventional group. [d1 (52.40 ± 10.43) g/L vs. (73.07 ± 19.32) g/L, d3 (126.10 ± 18.62) g/L vs. (160.72 ± 26.18) g/L)]. CONCLUSION: ERAS in lap-assisted total gastrectomy is safe, feasible and efficient and it can ameliorate post-operative stress and accelerate postoperative rehabilitation in patients with gastric cancer. Short term follow up results are encouraging but we need long term studies to know its long term benefits. PMID:25013329

    Subcostal transversus abdominis plane (TAP) blocks provide good postoperative analgesia for laparoscopic cholecystectomies. We hypothesised that adding hyaluronidase may improve the efficacy of this technique by increasing spread of the local anaesthetic (LA). In this case, we performed a bilateral ultrasound-guided subcostal TAP block using lignocaine (40 mL 1%) with hyaluronidase (75 IU/mL) for postoperative analgesia following elective laparoscopic cholecystectomy. It was used in combination with intraoperative morphine, diclofenac and paracetamol. Regular paracetamol was administered postoperatively. We monitored serial serum lignocaine levels and recorded the patient's visual analogue scale (VAS) pain scores postoperatively. We found that the patient experienced excellent analgesia throughout the postoperative period and that the serum lignocaine levels did not exceed the therapeutic range. PMID:24510699

    Background The treatment of ulcerative colitis (UC) patients with moderate to severe inflammatory activity with anti-tumor necrosis factor alpha (TNFα) antibodies leads to a clinical remission rate of 10% after 8 weeks of therapy. However, it must be taken into account that patient selection in clinical trials clearly influences both response and remission rates. An unsatisfactory response to anti-TNFα medication after week 12 often leads to a discontinuation of treatment. The early prediction of clinical response could therefore help optimize therapy and potentially avoid ineffective treatments. Objective The aim of this study is to develop an algorithm for optimizing golimumab administration in patients with moderate to severe UC by calculating the probability of clinical response in Week 26 based on data from Week 6. Methods The study is designed as a prospective, single-arm, multicenter, non-interventional observational study with no interim analyses and a sample size of 58 evaluable patients. The primary outcome is the prediction of clinical response in Week 26 based on a 50% reduction in fecal calprotectin and a positive golimumab trough level in Week 6. Results Enrollment started in October 2014 and was still open at the date of submission. The study is expected to finish in December 2016. Conclusions The early identification of patients who are responding to an anti-TNFα antibody is therapeutically beneficial. At the same time, patients who are not responding can be identified earlier. The development of a therapeutic algorithm for identifying patients as responders or non-responders can thus help prescribing physicians to both avoid ineffective treatments and adjust dosages when necessary. This in turn promotes a higher degree of treatment tolerance and patient safety in the case of anti-TNFα antibody administration.

    Two hundred patients were enrolled in a randomized, prospective clinical trial comparing the use of 10-0 nylon, 10-0 polypropylene (Prolene), 11-0 polyester (Mersilene), and 10-0 polyethylene (Novafil) suture materials on the amount and decay curves of surgically induced astigmatism following intraocular lens (IOL) surgery. Patients with Mersilene and nylon sutures had the highest amounts of induced with-the-rule (WTR) cylinder (significantly more than Prolene) at one day after surgery. However, the WTR cylinder decayed rapidly for nylon during the first three months but more slowly for Mersilene because of its lack of stretchability. The Prolene group had the lowest level of induced WTR cylinder at one day, but against-the-rule (ATR) drift occurred, leaving cases with ATR astigmatism by a year. The nylon group had the second highest amount of induced WTR cylinder at one day, which had decayed to ATR cylinder by five months. Between one and two years postoperatively, the nylon group experienced a significant ATR shift.

    Postoperative acute pulmonary embolism after pulmonary resections is highly fatal complication. Many literatures have documented cancer to be the highest risk factor for acute pulmonary embolism after pulmonary resections. Early diagnosis of acute pulmonary embolism is highly recommended and computed tomographic pulmonary angiography is the gold standard in diagnosis of acute pulmonary embolism. Anticoagulants and thrombolytic therapy have shown a great success in treatment of acute pulmonary embolism. Surgical therapies (embolectomy and inferior vena cava filter replacement) proved to be lifesaving but many literatures favored medical therapy as the first choice. Prophylaxis pre and post operation is highly recommended, because there were statistical significant results in different studies which supported the use of prophylaxis in prevention of acute pulmonary embolism. Having reviewed satisfactory number of literatures, it is suggested that thoroughly preoperative assessment of patient conditions, determining their risk factors complicating to pulmonary embolism and the use of appropriate prophylaxis measures are the key options to the successful minimization or eradication of acute pulmonary embolism after lung resections.

    Cytomegalovirus (CMV) infection is nonpermissive or persistent in many lymphoid and myeloid cell types but can be activated in differentiated macrophages. We have shown elsewhere that both the major immediate-early gene (MIE) and lytic cycle infectious progeny virus expression can be induced in otherwise nonpermissive monocyte-like U-937 cell cultures infected with either human CMV (HCMV) or simian CMV (SCMV) by treatment with the phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA). Two multicopy basal enhancer motifs within the SCMV MIE enhancer, namely, 11 copies of the 16-bp cyclic AMP response element (CRE) and 3 copies of novel 17-bp serum response factor (SRF) binding sites referred to as the SNE (SRF/NFkappaB-like element), as well as four classical NFkappaB sites within the HCMV version, contribute to TPA responsiveness in transient assays in monocyte and T-cell types. The SCMV SNE sites contain potential overlapping core recognition binding motifs for SRF, Rel/NFkappaB, ETS, and YY1 class transcription factors but fail to respond to either serum or tumor necrosis factor alpha. Therefore, to evaluate the mechanism of TPA responsiveness of the SNE motifs and of a related 16-bp SEE (SRF/ETS element) motif found in the HCMV and chimpanzee CMV MIE enhancers, we have examined the functional responses and protein binding properties of multimerized wild-type and mutant elements added upstream to the SCMV MIE or simian virus 40 minimal promoter regions in the U-937, K-562, HL-60, THP-1, and Jurkat cell lines. Unlike classical NFkappaB sites, neither the SNE nor the SEE motif responded to phosphatase inhibition by okadaic acid. However, the TPA responsiveness of both CMV elements proved to involve synergistic interactions between the core SRF binding site (CCATATATGG) and the adjacent inverted ETS binding motifs (TTCC), which correlated directly with formation of a bound tripartite complex containing both the cellular SRF and ELK-1 proteins.

    Post-operative peritonitis (PP) is a life-threatening hospital-acquired intra-abdominal infection with high rates of mortality. Diffuse PP remains a challenge for surgeons. Prognosis and outcome of patients are directly related to early diagnosis and prompt intervention. The diagnosis of PP may be difficult because there are no specific clinical signs and laboratory tests to reject or confirm the diagnosis. Atypical clinical features may be responsible for a delay in reoperation. An early diagnosis and prompt treatment is crucial to prevent the development of organ failure and improve the outcome of the patients with PP. The cornerstones in the management of patients with PP are early hemodynamic support, prompt source control and adequate antimicrobial therapy.

    The digestive fistula is one of the most serious complications that might appear following different types of resectional digestive surgery. This condition still carries a considerable morbidity and mortality rate and therefore all surgical and ICU staff pay a great deal of attention and intensify their care to avoid the fatalities. The postoperative digestive fistulas, through their physiopathological and clinical complexity induce the disturbance of the biological equilibrium with vital consequences. The trend of the last decades is the increasing of digestive fistulas incidence with a variable mortality rate after different authors. A therapeutic algorithm is needed. The mortality rate due to digestive fistulas, two decades ago was, around 60%; at the present there is a decrease of the mortality rate, which is around 10%. The explanation is the introduction of the new methods of treatment such as lactic acid lavage aspiration for alkaline fistulas or total parenteral nutrition, continuous enteral nutrition and antiexocrine chemotherapy. A fistula is a communication between two epithelial or endothelial surfaces, lined by granulation tissue. It can be a life-threatening condition. PMID:21495307

    2013-01-01

    Pre-operative assessment is required prior to the majority of elective surgical procedures, primarily to ensure that the patient is fit to undergo surgery, whilst identifying issues that may need to be dealt with by the surgical or anaesthetic teams. The post-operative management of elective surgical patients begins during the peri-operative period and involves several health professionals. Appropriate monitoring and repeated clinical assessments are required in order for the signs of surgical complications to be recognised swiftly and adequately. This article examines the literature regarding pre-operative assessment in elective orthopaedic surgery and shoulder surgery, whilst also reviewing the essentials of peri- and post-operative care. The need to recognise common post-operative complications early and promptly is also evaluated, along with discussing thromboprophylaxis and post-operative analgesia following shoulder surgery.

    Abstract The aim was to evaluate the nutritional situation of patients admitted to the Postoperative Acute Care Unit using classic methods of objective anthropometry, systemic evaluation methods, and Nutrition Risk in Critically Ill (NUTRIC) score, and to compare them as a predictor of morbidity and mortality. At admission to the postoperative care unit, patients undergoing various surgeries were assessed for the following items: Subjective Global Assessment (SGA), Nutritional Risk Index (NRI), Nutritional Risk Screening (NRS)-2002, Mini Nutritional Assessment (MNA), Charlson comorbidity index (CCI), and NUTRIC score, anthropometric measurements, serum total protein, serum albumin, and lymphocyte count. Patients were monitored for postoperative complications until death or discharge. Correlation of complications with these parameters was also analyzed. A total of 152 patients were included in the study. In this study a positive correlation was determined between mortality and NRS-2002, SGA, CCI, Acute Physiology and Chronic Health Evaluation , Sepsis-related Organ Failure Assessment, and NUTRIC score, whereas a negative correlation was determined between mortality and NRI. There was a correlation between NUTRIC score and pneumonia, development of atrial fibrillation, delirium, renal failure, inotrope use, and duration of mechanical ventilation. In our study group of postoperative patients, MNA had no predictive properties for any complication, whereas SGA had no predictive properties for any complications other than duration of hospital stay and mortality. The NUTRIC score is an important indicator of mortality and morbidity in postoperative surgical patients. NRI correlated with many postoperative complications, and though SGA and NRS were correlated with mortality, they were not correlated with the majority of complications. MNA was determined not to have any correlation with any complication, mortality, and duration of hospital stay in our patient group. PMID

    Postoperative nausea and vomiting (PONV) is a complication affecting between 20 and 40% of all surgery patients, with high-risk patients experiencing rates of up to 80%. Recent studies and publications have shed light on the uses of alternative treatment for PONV through their modulation of endogenous opioid neuropeptides and neurokinin ligands. In addition to reducing PONV, hypnosis was reported to be useful in attenuating postoperative pain and anxiety, and contributing to hemodynamic stability. Music therapy has been utilized to deepen the sedation level and decrease patient anxiety, antiemetic and analgesic requirements, hospital length of stay, and fatigue. Isopropyl alcohol and peppermint oil aromatherapy have both been used to reduce postoperative nausea. With correct training in traditional Chinese healing techniques, acupuncture (APu) at the P6 acupoint has also been shown to be useful in preventing early PONV, postdischarge nausea and vomiting, and alleviating of pain. Electro-acupuncture (EAPu), as with APu, provided analgesic and antiemetic effects through release and modulation of opioid neuropeptides. These non-pharmacological modalities of treatment contribute to an overall patient wellbeing, assisting in physical and emotional healing. PMID:26734609

    Postoperative ileus (POI) is an abnormal pattern of gastrointestinal motility characterized by nausea, vomiting, abdominal distension and/or delayed passage of flatus or stool, which may occur following surgery. Postoperative ileus slows recovery, increases the risk of developing postoperative complications and confers a significant financial load on healthcare institutions. The aim of the present review is to provide a succinct overview of the clinical features and pathophysiological mechanisms of POI, with final comment on selected directions for future research.Terminology used when describing POI is inconsistent, with little differentiation made between the obligatory period of gut dysfunction seen after surgery ('normal POI') and the more clinically and pathologically significant entity of a 'prolonged POI'. Both normal and prolonged POI represent a fundamentally similar pathophysiological phenomenon. The aetiology of POI is postulated to be multifactorial, with principal mediators being inflammatory cell activation, autonomic dysfunction (both primarily and as part of the surgical stress response), agonism at gut opioid receptors, modulation of gastrointestinal hormone activity and electrolyte derangements. A final common pathway for these effectors is impaired contractility and motility and gut wall oedema. There are many potential directions for future research. In particular, there remains scope to accurately characterize the gastrointestinal dysfunction that underscores an ileus, development of an accurate risk stratification tool will facilitate early implementation of preventive measures and clinical appraisal of novel therapeutic strategies that target individual pathways in the pathogenesis of ileus warrant further investigation.

    Postoperative cognitive dysfunction (POCD) is a common complication that presents in the postoperative stage, especially in elderly patients. Despite years of considerable progress, the detailed molecular mechanisms of POCD remain largely unknown. Neuroinflammation has been increasingly pointed out as one of the core mechanisms for the pathogenesis of POCD. However, application of anti-inflammatory drugs failed to show consistent beneficial effect in patients with cognitive decline. Hence, it might be of great importance to identify the inflammatory initiators that are involved in the mediation, amplification and perpetuation of postoperative neuroinflammatory reactions. Extracellular RNAs (exRNAs), released from necrotic cells, were demonstrated to initiate the inflammatory responses in various pathological conditions. Recent study has suggested neuroprotective and edema protective effects of ribonuclease (RNase), the counterpart of RNA, in acute stroke. It was theorized that RNase acted against endogenous RNA that was released from tissue damage. Similarly, we have observed significant attenuation of cognitive impairment by RNase in aged mice after unilateral nephrectomy. Damping the systemic initiators at early stages may help to prevent the chain reaction that triggers the central inflammatory or apoptotic response. Therefore, we propose the hypothesis that exRNAs released upon stress, through acting on the peripheral and/or central receptors, may trigger a damaging cascade leading to the development of POCD. Undoubtedly, further study is urgently needed to elucidated the exact signaling mechanisms and confirm the proposed hypothesis. PMID:27515198

Anterior segment examination showed a 2-mm-layered hypopyon, a well-centered intraocular lens in the sulcus, and an obscured view to the fundus. B-scan ultrasonography showed significant vitritis and that the retina was attached. A tap and an injection of vancomycin 1 mg per 0.1 ml and of ceftazidime 2.25 mg per 0.1 ml were performed. The tap eventually yielded culture results positive for Staphylococcus haemolyticus, which was sensitive to vancomycin. We report a case of endophthalmitis that occurred on postoperative day 1 following complicated cataract surgery. This is an uncommon bacterium that is not widely reported in the literature as a cause of endophthalmitis in the postoperative period. We urge clinicians to consider S. haemolyticus as an offending agent, especially when the infection presents very early and aggressively in the postoperative period.

    Thirty postoperative patients, after undergoing abdominal hysterectomy and standard general anesthesia, were randomly allocated to three groups and received, in the recovery ward, a continuous infusion of either pentazocine, piritramide, or ketamine. The patients rated their pain on a 15-cm visual analog scale. Patients in group 1 received pentazocine. Mean dosage was 0.12 mg/kg/hr on the day of operation, 0.1 mg/kg/hr on the first postoperative day, and only 0.07 mg/kg/hr on the second postoperative day. Pentazocine blood levels averaged 50 micrograms/L. Patients in group 2 received piritramide. Mean dosage was 0.038 mg/kg/hr on the day of operation, 0.024 mg/kg/hr on the first postoperative day, and 0.019 mg/kg/hr on the second postoperative day. Blood levels of piritramide were not determined because no satisfactory assay is available. Patients in group 3 received ketamine. Mean dosage was 0.32 mg/kg/hr on the day of operation, 0.28 mg/kg/hr on the first postoperative day, and 0.29 mg/kg/hr on the second postoperative day. Ketamine blood levels ranged between 120 and 180 micrograms/L. None of the three analgesics caused any important hemodynamic or respiratory side effects. Pentazocine and piritramide were more effective analgesics than ketamine was. Ketamine also had a higher incidence of side effects. PMID:6627285

    Purpose During laparoscopic gastrectomy, an aberrant left hepatic artery (ALHA) arising from the left gastric artery (LGA) is occasionally encountered. The aim of this study was to define when an ALHA should be preserved during laparoscopic gastrectomy. Materials and Methods From August 2009 to December 2014, 1,340 patients with early gastric cancer underwent laparoscopic distal gastrectomy. One hundred fifty patients presented with an ALHA; of the ALHA was ligated in 116 patients and preserved in 34 patients. Patient characteristics, postoperative outcomes and perioperative liver function tests were reviewed retrospectively. Correlations between the diameter of the LGA measured on preoperative abdominal computed tomography and postoperative liver enzyme levels were analyzed. Results Pearson's correlation analysis showed a positive correlation between the diameter of the LGA and serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels on postoperative day 1 in the ALHA-ligated group (P=0.039, P=0.026, respectively). Linear regression analysis estimated the diameter of the LGA to be 5.1 mm and 4.9 mm when AST and ALT levels were twice the normal limit on postoperative day 1. Conclusions We suggest preserving the ALHA arising from a large LGA, having diameter greater than 5 mm, during laparoscopic gastrectomy to prevent immediate postoperative hepatic dysfunction.

    Primary laryngeal carcinoma is a common cancer, predominantly affecting males. Hypothyroidism is an undesirable sequela of both surgery and radiotherapy, the two most commonly used modalities of treatment. For advanced cases, standard treatment protocol includes total laryngectomy and neck dissection along with pre- or postoperative radiotherapy. Hemithyroidectomy is also routinely performed as an integral part of total laryngectomy. In the present study, assessment of the function of the remaining half of the thyroid gland has been done in cases of total laryngectomies in combination with uni- or bilateral neck dissection and pre- or postoperative radiotherapy. This prospective, observational study was carried out for a period of 5 years in the Otolaryngology Department of R.G. Kar Medical College and Hospital, Kolkata, India, involving a dynamic cohort of patients with advanced laryngeal carcinoma (stage T3 or T4a) who underwent total laryngectomy (including hemithyroidectomy) and bilateral or unilateral neck dissection for primary laryngeal cancer along with preoperative and postoperative radiotherapy. Assessment of the thyroid function was based on the measurement of serum thyroid-stimulating hormone and free thyroxine levels. The results revealed that 23.8%, 45.2%, and 73.8% patients developed either clinical or subclinical hypothyroid state at 6, 12, and 24 weeks, respectively, after the surgery. The estimation of relative risk (RR) was found to be most prominent among the group belonging to the "preoperative radiation with bilateral neck dissection" group at all levels of assessments, but all of the RRs were found to be insignificant per their 95% confidence intervals. Superiority of any method could not be established or refuted firmly due to the small sample size of the study. We presume that in the future, a study with a larger sample size, involving a meta-analysis of multicentric data, would be the most suitable method to throw some light on this issue

    CA 19-9 is a marker correlated to the clinical evolution of pancreatic adenocarcinoma. To analyze the clinical value of pre- and postoperative CA 19-9 serum levels in stage I and II pancreatic cancer. We analyzed 61 patients resected for pancreatic cancer. Patients were evaluated about the pre-operative CA 19-9 values and then divided into 3 groups: high, high-low and low, on the basis of pre- and postoperative CA 19-9 levels. The correlations between these groups and age, sex, pT, pN, tumor stage, jaundice, surgical radicality, tumor size, number of harvested and positive lymph nodes, grading, overall and major morbidities and post-operative mortality together with survival rates were analyzed. Higher values of pre-operative CA 19-9 were significantly correlated to the presence of jaundice, high pT, pN, stage and higher number of metastatic lymph nodes. In 49 patients (80.3 %) an R0 resection was performed. Five-year overall survival (OS) and disease free survival (DFS) were significantly better in patients with high levels of pre-operative CA 19-9, even in R0 cases. After stratification, 30 patients were included in the high group, 13 in the high-low group and 18 in the low group. A statistically significant correlation was found between the CA 19-9 groups and the lymph nodal positivity, not between CA 19-9 and pT. OS and DFS were significantly better in low group patients. We confirm the prognostic value of preoperative CA 19-9 serum levels. We do not support early postoperative modifications of CA19-9 as an adjunctive prognostic variable.

    Ultrasonography of the postoperative musculoskeletal system plays an important role in the Epub ahead of print accurate diagnosis of abnormal lesions in the bone and soft tissues. Ultrasonography is a fast and reliable method with no harmful irradiation for the evaluation of postoperative musculoskeletal complications. In particular, it is not affected by the excessive metal artifacts that appear on computed tomography or magnetic resonance imaging. Another benefit of ultrasonography is its capability to dynamically assess the pathologic movement in joints, muscles, or tendons. This article discusses the frequent applications of musculoskeletal ultrasonography in various postoperative situations including those involving the soft tissues around the metal hardware, arthroplasty, postoperative tendons, recurrent soft tissue tumors, bone unions, and amputation surgery.

    Osteoarthritis (OA) is a degenerative process involving the progressive loss of articular cartilage, synovial inflammation and structural changes in subchondral bone that lead to loss of synovial joint structural features and functionality of articular cartilage. OA represents one of the most common causes of physical disability in the world. Different OA treatments are usually considered in relation to the stage of the disease. In the early stages, it is possible to recommend physical activity programs that can maintain joint health and keep the patient mobile, as recommended by OA Research Society International (OARSI) and European League Against Rheumatism (EULAR).

    Osteoarthritis (OA) is a degenerative process involving the progressive loss of articular cartilage, synovial inflammation and structural changes in subchondral bone that lead to loss of synovial joint structural features and functionality of articular cartilage. OA represents one of the most common causes of physical disability in the world. Different OA treatments are usually considered in relation to the stage of the disease. In the early stages, it is possible to recommend physical activity programs that can maintain joint health and keep the patient mobile, as recommended by OA Research Society International (OARSI) and European League Against Rheumatism (EULAR). In the most severe and advanced cases of OA, surgical intervention is necessary. After, in early postoperative stages, it is essential to include a rehabilitation exercise program in order to restore the full function of the involved joint.

  17. Heterogeneous nuclear ribonucleoprotein K (hnRNP K) is a tissue biomarker for detection of early Hepatocellular carcinoma in patients with cirrhosis

    PubMed Central

    2012-01-01

    Background Hepatocellular carcinoma (HCC) is one of the most common malignant tumors occurring mainly in patients with chronic liver disease. Detection of early HCC is critically important for treatment of these patients. Methods We employed a proteomic profiling approach to identify potential biomarker for early HCC detection. Based on Barcelona Clinic Liver Cancer (BCLC) staging classification, 15 early HCC and 25 late HCC tissue samples from post-operative HCC patients and their clinicopathological data were used for the discovery of biomarkers specific for the detection of early HCC. Differential proteins among cirrhotic, early, and late tissue samples were separated by two-dimensional gel electrophoresis (2-DE) and subsequently identified by mass spectrometry (MS). Receiver operating characteristic (ROC) curves analysis were performed to find potential biomarkers associated with early HCC. Diagnosis performance of the biomarker was obtained from diagnosis test. Results Protein spot SSP2215 was found to be significantly overexpressed in HCC, particularly in early HCC, and identified as heterogeneous nuclear ribonucleoprotein K (hnRNP K) by tandem mass spectrometry (MALDI TOF/TOF). The overexpression in HCC was subsequently validated by western blot and immunohistochemistry. ROC curve analysis showed that hnRNP K intensity could detect early HCC at 66.67 % sensitivity and 84 % specificity, which was superior to serum α-fetoprotein (AFP) in detection of early HCC. Furthermore, the diagnosis test demonstrated, when combined with hnRNP K and serum AFP as biomarker panel to detect early HCC at different cut-off value, the sensitivity and specificity could be enhanced to 93.33 % and 96 %, respectively. Conclusions hnRNP K is a potential tissue biomarker, either alone or in combination with serum AFP, for detection of early HCC. High expression of hnRNP K could be helpful to discriminate early HCC from a nonmalignant nodule, especially for patients with liver

    Objectives: Unexpected systemic inflammatory response with high fever and increase in C-reactive protein (CRP) occurred frequently after endovascular abdominal aortic aneurysm repair (EVAR). This excessive inflammatory response affects the postoperative course. We evaluated the effects of steroid on the postoperative inflammatory response after EVAR. Methods: Steroid therapy, intravenous infusion of methylprednisolone 1000 mg just after the anesthesia induction, was started since December 2012. After induction of the steroid therapy, 25 patients underwent EVAR with steroid therapy (Group S). These patients were compared with the 65 patients who underwent EVAR without steroid therapy (Group C) in white blood cell count (WBC), CRP and maximum body temperature (BT) on postoperative day 1–5. Results: There was no significant difference in age, female gender, operation time, maximum aneurysm diameter between the two groups. There was no postoperative infective complication in the both groups. WBC did not differ between the two groups; however, CRP was significantly suppressed in Group S than in Group C on POD 1, 3 and 5. Also BT was significantly lower in Group S than Group C on POD 1, 2 and 3. Conclusions: Steroid pretreatment before implantation of the stent graft reduces the early postoperative inflammatory response after EVAR, without increasing postoperative infection.

    The aim of this study is to describe and relate nutritional and inflammatory status and prognostic indexes with postoperative complications and clinical outcome of patients with gastrointestinal malignancies. Twenty-nine patients were evaluated; nutritional assessment was carried out by subjective and objective parameters; albumin, pre-albumin, C-reactive protein (CRP), and alpha-1-acid glycoprotein (AGP) were determined. To assess prognosis, the Glasgow scale, the Prognostic Inflammatory Nutritional Index (PINI), and CRP/albumin ratio were used; the clinical outcomes considered were hospital discharge and death. A high Subjective Global Assessment (SGA) score was associated with the occurrence of postoperative complications: 73% of the patients with postoperative complications had the highest SGA score, but only 6% of those without postoperative complications had the highest SGA score (P < 0.001). Greater occurrence of death was observed in patients with a high SGA score, low serum albumin, increased CRP, PINI > 1, and Glasgow score 2. There was a positive correlation between weight loss percentage with serum CRP levels (P = 0.002), CRP/albumin (P = 0.002), PINI (P = 0.002), and Glasgow score (P = 0.000). This study provides evidence that the assessment of the nutritional status and the use of prognostic indexes are good tools for predicting postoperative complications and clinical outcome in patients with gastrointestinal neoplasia.

    ABSTRACT Background: The bariatric surgery may cause some nutritional deficiencies. Aim: To compare the serum levels of biochemical markers, in iimmediate post-surgical patients who were submitted to bariatric surgery. Methods: Non-concurrent prospective cross-sectional study. The analysis investigated data in medical charts of pre-surgical and immediate post-surgical patients who were submitted to bariatric surgery, focusing total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, C reactive protein, vitamin B12 levels, folic acid, homocysteine values, iron and serum calcium at the referred period. Results: Twenty-nine patients of both genders were evaluated. It was observed weight loss from 108.53 kg to 78.69 kg after the procedure. The variable LDL-c had a significant difference, decreasing approximately 30.3 mg/dl after the surgery. The vitamin B12 serum average levels went from 341.9 pg/ml to 667.2 pg/ml. The triglycerides values were in a range of 129.6 mg/dl-173.3 mg/dl, and 81.9 mg/dl-105.3 mg/dl at the pre- and postoperative respectively. CRP levels fall demonstrated reduction of inflammatory activity. The variable homocysteine was tested in a paired manner and it did not show a significant changing before or after, although it showed a strong correlation with LDL cholesterol. Conclusion: Eligible patients to bariatric surgery frequently present pre-nutritional deficiencies, having increased post-surgical risks when they don´t follow an appropriate nutritional follow-up.

    PubMed

    2004-04-01

    Neurosurgery has for a long time been considered as a minimal painful surgery. This explains why there are few references in the literature concerning postoperative neurosurgical pain. Recent papers have demonstrated that even if postoperative pain is less important than in other specialities, such pain exists and should be taken care of. Rapid neurological recovery is now possible because of the progress in the surgical techniques and the introduction of new anaesthetic drugs. This implies a strict postoperative analgesic strategy in order to avoid both direct and indirect complications associated with pain. In this respect, the use of remifentanil or other techniques like target-controlled injection of opioids should absolutely be considered. In most cases, class I and II analgesics seem to provide optimal pain relief. However, for some patients, the use of an opioid may be required. PMID:15120790

    Good pain control after surgery is important to prevent negative outcomes such as tachycardia, hypertension, myocardial ischemia, decrease in alveolar ventilation, and poor wound healing. Exacerbations of acute pain can lead to neural sensitization and release of mediators both peripherally and centrally. Clinical wind up occurs from the processes of N-Methyl D-Aspartate (NMDA) activation, wind up central sensitization, long-term potentiation of pain (LTP), and transcription-dependent sensitization. Advances in the knowledge of molecular mechanisms have led to the development of multimodal analgesia and new pharmaceutical products to treat postoperative pain. The new pharmacological products to treat postoperative pain include extended-release epidural morphine and analgesic adjuvants such as capsaicin, ketamine, gabapentin, pregabalin dexmetomidine, and tapentadol. Newer postoperative patient-controlled analgesia (PCA) in modes such as intranasal, regional, transdermal, and pulmonary presents another interesting avenue of development. PMID:20351978

    Pulmonary complications are a major cause of morbidity and mortality in the post-operative period after thoracotomy. The type of complications and the severity of complications depend on the type of thoracic surgery that has been performed as well as on the patient's pre-operative medical status. Risk stratification can help in predicting the possibility of the post-operative complications. Certain airway complications are more prone to develop with thoracic surgery. Vocal cord injuries, bronchopleural fistulae, pulmonary emboli and post-thoracic surgery non-cardiogenic pulmonary oedema are some of the unique complications that occur in this subset of patients. The major pulmonary complications such as atelectasis, bronchospasm and pneumonia can lead to respiratory failure. This review was compiled after a search for search terms within 'post-operative pulmonary complications after thoracic surgery and thoracotomy' on search engines including PubMed and standard text references on the subject from 2000 to 2015.

    This paper describes a research study to investigate the efficacy of peppermint oil as a treatment for postoperative nausea. It uses a three-condition experimental design using statistical analysis to compare groups. The Kruskal-Wallis test was used to establish significance and the Mann-Whitney test to differentiate significance between the groups. The control, placebo and experimental groups of gynaecological patients were compared, using variables known to affect postoperative nausea. They were found to be homogeneous for the purposes of the study. A statistically significant differences was demonstrated on the day of operation, using the Kruskal-Wallis test, P = 0.0487. Using the Mann-Whitney test the difference was shown to be between the placebo and experimental group (U = 3; P = 0.02). The experimental group also required less traditional antiemetics and received more opioid analgesia postoperatively. The total cost of the treatment was 48 pence per person.

    Elderly surgical patients frequently experience postoperative delirium (POD) and the subsequent development of postoperative cognitive dysfunction (POCD). Clinical features include deterioration in cognition, disturbance in attention and reduced awareness of the environment and result in higher morbidity, mortality and greater utilization of social financial assistance. The aging Western societies can expect an increase in the incidence of POD and POCD. The underlying pathophysiological mechanisms have been studied on the molecular level albeit with unsatisfying small research efforts given their societal burden. Here, we review the known physiological and immunological changes and genetic risk factors, identify candidates for further studies and integrate the information into a draft network for exploration on a systems level. The pathogenesis of these postoperative cognitive impairments is multifactorial; application of integrated systems biology has the potential to reconstruct the underlying network of molecular mechanisms and help in the identification of prognostic and diagnostic biomarkers.

    Visual laser ablation of the prostate (VLAP) has been shown to be as effective with fewer complications than TURP in the treatment of bladder outlet obstruction secondary to benign prostatic hyperplasia. Questions have been raised about VLAP regarding prolonged irritative and obstructive voiding symptoms postoperatively. It is postulated that these symptoms are due to the slow slough of necrotic debris following VLAP. In an effort to improve upon the technique of VLAP, patients underwent lasing of the prostate in the routine manner (2, 4, 8, and 10 o'clock positions with sixty watts for sixty seconds) using Nd:YAG free beam energy. A bladder neck incision was then performed using a contact laser fiber. International prostate symptom score assessments were done preoperatively; one week and six weeks postoperatively. Post void residual urine volumes and prostate size were also evaluated. The findings indicate that symptom scores and post void residual urine volumes have significantly improved within ten days postoperatively using this technique.

    Pain is a major postoperative symptom in many oral surgical procedures. It is a complex and variable phenomenon that can be influenced by many factors. Good management of oral surgical pain requires a detailed understanding of the pathogenesis of surgical pain. This article aims at reviewing postoperative pain from a broad perspective by looking into the nociception, neuroanatomy, neurophysiology, and neuropharmacology of pain. Therapeutic recommendations are made after reviewing the evidence from the literature for maximizing the efficacy of pain management techniques for oral surgical pain. PMID:12722900

    Global postoperative amnesia (profound anterograde and retrograde amnesia) is rare and usually attributed to transient global amnesia-a poorly understood condition with no broadly accepted mechanism. We report an incident of probable transient global amnesia in a patient after endoscopic retrograde cholangiopancreatogram under general anesthesia, which was successfully treated with flumazenil. On the basis of the results of flumazenil administration in this and a previous case report, we would recommend a trial dose of 0.2 mg for cases of global postoperative amnesia, repeated if the first dose seems effective.

    ABSTRACT Purpose: To determine the predictive factors for postoperative urinary incontinence (UI) following holmium laser enucleation of the prostate (HoLEP) during the initial learning period. Patients and Methods: We evaluated 127 patients with benign prostatic hyperplasia who underwent HoLEP between January 2011 and December 2013. We recorded clinical variables, including blood loss, serum prostate-specific antigen levels, and the presence or absence of UI. Blood loss was estimated as a decline in postoperative hemoglobin levels. The predictive factors for postoperative UI were determined using a multivariable logistic regression analysis. Results: Postoperative UI occurred in 31 patients (24.4%), but it cured in 29 patients (93.5%) after a mean duration of 12 weeks. Enucleation time >100 min (p=0.043) and blood loss >2.5g/dL (p=0.032) were identified as significant and independent risk factors for postoperative UI. Conclusions: Longer enucleation time and increased blood loss were independent predictors of postoperative UI in patients who underwent HoLEP during the initial learning period. Surgeons in training should take care to perform speedy enucleation maneuver with hemostasis. PMID:27564285

    Background Primary spontaneous pneumothorax (PSP) is a relatively common disorder in young patients. Although various surgical techniques have been introduced, recurrence after video-assisted thoracoscopic surgery (VATS) remains high. The aim of study was to identify the risk factors for postoperative recurrence after thoracoscopic bullectomy in the spontaneous pneumothorax. Methods From January 2011 through March 2013, two hundreds and thirty two patients underwent surgery because of pneumothorax. Patients with a secondary pneumothorax, as well as cases of single port surgery, an open procedure, additional pleural procedure (pleurectomy, pleural abrasion) or lack of medical records were excluded. The records of 147 patients with PSP undergoing 3-port video-assisted thoracoscopic bullectomy with staple line coverage using an absorbable polyglycolic acid (PGA) sheet were retrospectively reviewed. Results The median age was 19 years (range, 11−34 years) with male predominance (87.8%). Median postoperative hospital stay was 3 days (range, 1−10 days) without mortality. Complications were developed in five patients. A total of 24 patients showed postoperative recurrence (16.3%). Younger age less than 17 years old and immediate postoperative air leakage were risk factors for postoperative recurrence after thoracoscopic bullectomy by multivariate analysis. Conclusions Immediate postoperative air leakage was the risk factor for postoperative recurrence. However, further study will be required for the correlation of air leakage with recurrence.

    While classic teaching dictates computed tomography (CT) for postoperative abdominal or pelvic abscess in the first week is of low yield, little evidence supports intentional delays in imaging for suspected abscess. This retrospective review examined all CT scans obtained for clinical suspicion of abscess between 3 and 30 days after abdominal or pelvic operation over a 3-year period. Scans were grouped into those obtained between 3 and 7 days after surgery (EARLY) and those obtained after day 7 (LATE). Diagnostic yield was compared between EARLY and LATE groups. Of 262 CT examinations (EARLY, n = 106; LATE, n = 156), 71 studies (27%) demonstrated abscess. There was no significant difference in the diagnostic yield of CT for abscess between EARLY and LATE groups (23% [24 of 106] versus 30% [47 of 156], P = 0.18). Of patients with an abscess, 63% (45 of 71) underwent percutaneous or operative drainage (EARLY 75% [18 of 24], LATE 57% [27 of 47], P = 0.15). Abdominal CT for postoperative abscess can be expected to be diagnostic in a substantial proportion of cases in the first week, the majority of which lead to percutaneous or operative drainage. Postoperative CT for intra-abdominal abscess should be obtained as clinically indicated, regardless of interval from surgery.

    The postoperative growth rates achieved in eight early pubertal adolescent males with Crohn's disease undergoing surgery for obstructive complications is reported as a function of the use of 1 month's preoperative central venous alimentation. All patients had ileal strictures with ileocolitis, bone ages less than 13, Tanner stages 1 or 2, and growth velocities below the 3rd percentile for age. During a 3-year follow-up, those receiving preoperative venous alimentation demonstrated greater oral caloric intake (significant for 1 year) and greater postoperative growth velocity (significant for 2 years) in comparison to those patients who did not receive preoperative venous alimentation. There was no significant difference between the two groups of patients in postoperative weight gain, sexual development, and 3-year disease control.

    Anastomotic leak is a major complication after colorectal resection. Risk factors for anastomotic leak include patient and disease related factors, preoperative factors(e.g. use of neoadjuvant chemoradiation and mechanical bowel preparation), intraoperative factors(e.g. anastomotic techniques, performing of water injection test, preventive colostomy, and surgical procedures, etc; postoperative factors, such as postoperative medication use, etc. Early diagnosis of anastomotic fistula is crucial, which can be made by combining laboratory examination with imaging examination or take the prediction and diagnosis model as reference. Once diagnosed, anastomotic leak should be managed immediately according to individual status and severity of disease. As for intraperitoneal anastomosis, no matter whether the bowel lack of blood supply or not, original anastomosis should be removed and terminal loop ileumstomy should be created. As for extraperitoneal anastomosis(mainly low rectal anastomosis), adequate drainage and terminal loop ileumstomy can be considered when anastomosis is slightly cracked or invisible due to adhesion. When anastomosis is severely cracked or blood supply is too limited, however, we must disconnect the original anastomotic and create a proximal colostomy.

    Background Preoperative anaemia is associated with adverse outcomes after surgery but outcomes after liver surgery specifically are not well established. We aimed to analyze the incidence of and effects of preoperative anemia on morbidity and mortality in patients undergoing liver resection. Methods All elective hepatectomies performed for the period 2005–2012 recorded in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database were evaluated. We obtained anonymized data for 30-day mortality and major morbidity (one or more major complication), demographics, and preoperative and perioperative risk factors. We used multivariable logistic regression models to assess the adjusted effect of anemia, which was defined as (hematocrit <39% in men, <36% in women), on postoperative outcomes. Results We obtained data for 12,987 patients, of whom 4260 (32.8%) had preoperative anemia. Patients with preoperative anemia experienced higher postoperative major morbidity and mortality rates compared to those without anemia. After adjustment for predefined variables, preoperative anemia was an independent risk factor for postoperative major morbidity (adjusted OR 1.21, 1.09–1.33). After adjustment, there was no significant difference in postoperative mortality for patients with or without preoperative anemia (adjusted OR 0.88, 0.66–1.16). Conclusion Preoperative anemia is independently associated with an increased risk of major morbidity in patients undergoing hepatectomy. Therefore, it is crucial to readdress preoperative blood management in anemic patients prior to hepatectomy. PMID:27017165

    2016-06-01

    Postoperative sore throat has a reported incidence of up to 62% following general anaesthesia. In adults undergoing tracheal intubation, female sex, younger age, pre-existing lung disease, prolonged duration of anaesthesia and the presence of a blood-stained tracheal tube on extubation are associated with the greatest risk. Tracheal intubation without neuromuscular blockade, use of double-lumen tubes, as well as high tracheal tube cuff pressures may also increase the risk of postoperative sore throat. The expertise of the anaesthetist performing tracheal intubation appears to have no influence on the incidence in adults, although it may in children. In adults, the i-gel(™) supraglottic airway device results in a lower incidence of postoperative sore throat. Cuffed supraglottic airway devices should be inflated sufficiently to obtain an adequate seal and intracuff pressure should be monitored. Children with respiratory tract disease are at increased risk. The use of supraglottic airway devices, oral, rather than nasal, tracheal intubation and cuffed, rather than uncuffed, tracheal tubes have benefit in reducing the incidence of postoperative sore throat in children. Limiting both tracheal tube and supraglottic airway device cuff pressure may also reduce the incidence.

    30 postoperative patients, who had undergone abdominal gynaecological surgery with standard general anaesthesia were randomly divided into three groups and received, in the recovery ward, a continuous infusion of either pentazocine, piritramid, or ketamine. The patients rated their pain on a 15 cm pain analogue score. Group I pentazocine: Mean dosage on the day of operation 0.12 mg/kg/h, 0.1 mg/kg/h on the first and only 0.07 mg/kg/h on the second postoperative day. Pentazocine blood levels were on average 50 micrograms/l. Group II piritramid: Mean dosage on the day of operation 0.038 mg/kg/h, 0.024 mg/kg/h on the first and 0.019 mg/kg/h on the second postoperative day. Blood levels of piritramid were not determined because there is no satisfactory assay available. Group III ketamine: mean dosage on the day of operation 0.32 mg/kg/h, 0.28 mg/kg/h on the first and 0.29 mg/kg/h on the second postoperative day. Ketamine blood levels lay between 120 and 180 micrograms/l. The three analgesics did not cause any important haemodynamic or respiratory side effects. Pentazocine and piritramid were the most effective analgesics, ketamine was the least effective with a high incidence of side effects. PMID:6412586

    Only recently has the use of anesthesia and analgesia become widely accepted in the newborn infant. This is largely a result of the overwhelming evidence that neonates have the neurologic substrate for the perception of pain and display characteristic behavioral, physiologic, metabolic, and hormonal responses to noxious stimuli. The management of postoperative pain in the surgical neonate begins in the operating room, where techniques can be chosen that will ease the transition into the postoperative period. For postoperative analgesia, the most widely used and effective agents are the narcotics morphine and fentanyl. They may be administered either intermittently or continuously, and with proper precautions may be given to both intubated and nonintubated newborns. Other medications for analgesia and sedation are not as well studied in the newborn, but chloral hydrate and the benzodiazepines are useful for sedation, and acetaminophen may be used for analgesia alone or for potentiating the effect of narcotics. In addition, a number of creative nonpharmacologic techniques are being developed and promise to further decrease the discomfort experienced by postoperative neonates.

    The purpose of this study was to assess the incidence and risk factors associated with postoperative nausea (PON) and vomiting (POV) after orthognathic surgery. A review of the clinical records of consecutively enrolled subjects (2008–2012) at a single academic institution was conducted between 9/2013 and 3/2014. Data on the occurrence of PON and POV and potential patient-related, intraoperative, and postoperative explanatory factors were extracted from the medical records. Logistic models were used for the presence/absence of postoperative nausea and vomiting separately. Data from 204 subjects were analyzed: 63% were female, 72% Caucasian, and the median age was 19 years. Thirty-three percent had a mandibular osteotomy alone, 27% a maxillary osteotomy alone, and 40% had bimaxillary osteotomies. Sixty-seven percent experienced PON and 27% experienced POV. The most important risk factors for PON in this series were female gender, increased intravenous fluids, and the use of nitrous oxide, and for POV were race, additional procedures, and morphine administration. The incidence of PON and POV following orthognathic surgery in the current cohort of patients, after the introduction of the updated 2007 consensus guidelines for the management of postoperative nausea and vomiting, has not decreased substantially from that reported in 2003–2004.

  20. Piezoelectric microcantilever serum protein detector

    NASA Astrophysics Data System (ADS)

    Capobianco, Joseph A.

    The development of a serum protein detector will provide opportunities for better screening of at-risk cancer patients, tighter surveillance of disease recurrence and better monitoring of treatment. An integrated system that can process clinical samples for a number of different types of biomarkers would be a useful tool in the early detection of cancer. Also, screening biomarkers such as antibodies in serum would provide clinicians with information regarding the patient's response to treatment. Therefore, the goal of this study is to develop a sensor which can be used for rapid, all-electrical, real-time, label-fee, in-situ, specific quantification of cancer markers, e.g., human epidermal receptor 2 (Her2) or antibodies, in serum. To achieve this end, piezoelectric microcantilever sensors (PEMS) were constructed using an 8 mum thick lead magnesium niobate-lead titanate (PMN-PT) freestanding film as the piezoelectric layer. The desired limit of detection is on the order of pg/mL. In order to achieve this goal the higher frequency lateral extension modes were used. Also, as the driving and sensing of the PEMS is electrical, the PEMS must be insulated in a manner that allows it to function in aqueous solutions. The insulation layer must also be compatible with standardized bioconjugation techniques. Finally, detection of both cancer antigens and antibodies in serum was carried out, and the results were compared to a standard commercialized protocol. PEMS have demonstrated the capability of detecting Her2 at a concentration of 5 pg/mL in diluted human serum (1:40) in less than 1 hour. The approach can be easily translated into the clinical setting because the sensitivity is more than sufficient for monitoring prognosis of breast cancer patients. In addition to Her2 detection, antibodies in serum were assayed in order to demonstrate the feasibility of monitoring the immune response for antibody-dependent cellular cytotoxicity (ADCC) in patients on antibody therapies

    IMPORTANCE Postoperative hypocalcemia is common after total thyroidectomy, and perioperative monitoring of serum calcium levels is arguably the primary reason for overnight hospitalization. Confidently predicting which patients will not develop significant hypocalcemia may allow for a safe earlier discharge. OBJECTIVE To examine associations of patient characteristics with hypocalcemia, duration of hospitalization, and postoperative intact parathyroid hormone (IPTH) level after total thyroidectomy. DESIGN, SETTING, AND PARTICIPANTS Retrospective study of consecutive patients who underwent total thyroidectomy by a single high-volume surgeon between February 1, 2010, and November 30, 2012. Postoperative serum 25-hydroxyvitamin D (vitamin D), calcium, and IPTH levels were tested within 6 to 8 hours after surgery. Mild hypocalcemia was defined as any postoperative serum calcium level of less than 8.4 to 8.0 mg/dL. Significant hypocalcemia was defined as any postoperative serum calcium level of less than 8.0 mg/dL or the development of hypocalcemia-related symptoms. INTERVENTIONS Total thyroidectomy. MAIN OUTCOMES AND MEASURES Associations of patient demographic and clinical characteristics and laboratory values with postoperative mild and significant hypocalcemia were examined using univariate analysis, and independent predictors of hypocalcemia, duration of hospitalization, and IPTH level were determined using multivariate analysis. RESULTS Overall, 304 total thyroidectomies were performed. Mild and significant hypocalcemia occurred in 68 (22.4%) and 91 (29.9%) patients, respectively, of which the majority were female (P = .003). The development of significant hypocalcemia was associated with postoperative IPTH level (P < .001). On multivariate analysis, males had a decreased risk of developing mild (odds ratio, 0.37 [95% CI, 0.16–0.85]) and significant (odds ratio, 0.57 [95% CI, 0.09–0.78]) hypocalcemia.

    Necrotizing enterocolitis (NEC) is severe disease of gastrointestinal tract, yet its early symptoms are nonspecific, easily interchangeable with sepsis. Therefore, reliable biomarkers for early diagnostics are needed in clinical practice. Here, we analyzed if markers of gut mucosa damage, caspase cleaved cytokeratin 18 (ccCK18) and intestinal fatty acid-binding protein (I-FABP), could be used for differential diagnostics of NEC at early stage of disease. We collected paired serum (at enrollment and week later) and urine (collected for two days in 6 h intervals) samples from 42 patients with suspected NEC. These patients were later divided into NEC (n = 24), including 13 after gastrointestinal surgery, and sepsis (n = 18) groups using standard criteria. Healthy infants (n = 12), without any previous gut surgery, served as controls. Both biomarkers were measured by a commercial ELISA assay. There were no statistically significant differences in serum ccCK18 between NEC and sepsis but NEC patients had significantly higher levels of serum and urinary I-FABP than either sepsis patients or healthy infants. Urinary I-FABP has high sensitivity (81%) and specificity (100%) and can even distinguish NEC from sepsis in patients after surgery. Urinary I-FABP can be used to distinguish NEC from neonatal sepsis, including postoperative one, better than abdominal X-ray. PMID:27110575

    Background To describe the morphology of a macular hole in the early postoperative period following vitrectomy with primary silicone oil tamponade. Methods A case report with optical coherence tomography (OCT) scans prior to surgery, at 20 minutes postoperatively and then at 17 hours postoperatively. Results OCT images of a 73-year-old woman with a stage 3 macular hole were obtained. At 20 minutes postoperatively, there was a reduction in intraretinal cysts and a reduction in macular hole size with elevated-open configuration. At 17 hours postoperatively, complete macular hole closure was noted. Conclusion OCT Images of a macular hole in the early postoperative period have been successfully obtained. Macular holes can close within 24 hours postoperatively and show morphological changes that may be predictive of closure within 20 minutes postoperatively. PMID:22140310

    In 1996, the U.S. Food and Drug Administration approved olestra, a fat substitute, for use in snack foods. Previous studies had shown that olestra consumption could reduce absorption of carotenoids and fat-soluble vitamins. To determine the association between consumption of olestra-containing snack foods and serum concentrations of carotenoids and fat-soluble vitamins in a free-living population, we interviewed independent population-based cross-sectional samples of 1043 adults before olestra was available and 933 adults 9 mo after olestra snacks were introduced into the marketplace in Marion County, IN, the first major test market for olestra. A cohort composed of 403 adults from the first survey, oversampling those most frequently reporting olestra consumption during follow-up telephone interviews, completed a second survey. We assessed diet, lifestyle factors and olestra consumption, and collected blood for assays for the serum concentrations of six carotenoids, four fat-soluble vitamins and lipids. Nine months after the introduction of olestra into the marketplace, 15.5% of Marion County residents reported consuming an olestra-containing snack in the previous month, with a median frequency among consumers of 3.0 times per month. There were no significant associations or consistent trends for decreased serum carotenoids or fat-soluble vitamins associated with olestra consumption, although cohort members consuming >/=2 g/d of olestra had adjusted total serum carotenoids 15% lower compared with baseline. There were increases in serum vitamin K concentrations associated with olestra consumption (P = 0.03 in the cross section and P = 0.06 in the cohort). In summary, there was no statistically significant evidence in this free-living population of associations between olestra consumption and decreased serum concentrations of carotenoids and fat-soluble vitamins.

    Tonsilloadenoidectomy performed on an 8-year old girl, in the course of which heavy bleeding from the left niche was staunched by suture ligation, was complicated from the 7th day onwards by severe haemorrhages at intervals from 5 to 25 days, causing life-threatening hypovolaemia. Haemorrhages started mostly in the early morning hours and ceased spontaneously. Revision of the left niche was undertaken shortly after the 5th bleeding two months postoperatively. After removal of the almost completely restituted mucosal covering, spreading of a haemosiderinstained canal released a massive pulsating haemorrhage which was controlled by ligation of the external carotid artery and suturing of the tonsillar bed. As the origin of the haemorrhage, an arterial lesion either by tonsil enucleation or by suture ligation is discussed. Attention is drawn to the possibility that certain branches of the external carotid artery may be positioned very close to the inferior half of the tonsil. PMID:3210878

    Pain is a predictable consequence following operations, but the management of postoperative pain is another challenge for anesthesiologists and inappropriately controlled pain may lead to unwanted outcomes in the postoperative period. Opioids are indeed still at the mainstream of postoperative pain control, but solely using only opioids for postoperative pain management may be connected with risks of complications and adverse effects. As a consequence, the concept of multimodal analgesia has been proposed and is recommended whenever possible. Acetaminophen is one of the most commonly used analgesic and antipyretic drug for its good tolerance and high safety profiles. The introduction of intravenous form of acetaminophen has led to a wider flexibility of its use during peri- and postoperative periods, allowing the early initiation of multimodal analgesia. Many studies have revealed the efficacy, safety and opioid sparing effects of intravenous acetaminophen. Intravenous ibuprofen has also shown to be well tolerated and demonstrated to have significant opioid sparing effects during the postoperative period. However, the number of randomized controlled trials confirming the efficacy and safety is small and should be used in caution in certain group of patients. Intravenous acetaminophen and ibuprofen are important options for multimodal postoperative analgesia, improving pain and patient satisfaction. PMID:25664148

    BACKGROUND: A number of studies have shown that the early mortality following TURP is higher for patients with prostate cancer than those with benign disease. This study examines the effect of the histological diagnosis on the predischarge complication rate following TURP. METHODS: Information on the postoperative, predischarge complications of 3036 patients, who underwent TURP over the last decade at our institution, was collated from the urology department database (AuditBase for Windows). The information on this database is collected prospectively, at the point of care and validated at monthly audit meetings. Statistical analyses were performed using chi2 and difference of proportion where n > 60. Statistical significance was taken as P < 0.05. RESULTS: The postoperative, predischarge major complication rate for patients with benign disease was 2.1%. This was not statistically different from the 2.3% complication rate seen in patients with malignant disease. Patients suffering a postoperative complication stayed in hospital significantly longer than those who had a straightforward postoperative course (P < 0.001); however, patients with malignant histology suffering a postoperative complication did not stay statistically significantly longer than those with benign histology suffering a postoperative complication (P < 0.1). CONCLUSIONS: Patients undergoing TURP for prostate cancer do not suffer more postoperative, predischarge complications or stay in hospital longer than patients undergoing TURP for benign disease.

    Open surgical repair (OSR) is a conventional surgical method used in the repair a ruptured abdominal aortic aneurysm (AAA); however, OSR results in high perioperative mortality rates. The level of serum angiotensin-converting enzyme 2 (ACE2) has been reported to be an independent risk factor for postoperative in-hospital mortality following major cardiopulmonary surgery. In the present study, the association of serum ACE2 levels with postoperative in-hospital mortality was investigated in patients undergoing OSR for ruptured AAA. The study enrolled 84 consecutive patients underwent OSR for ruptured AAA and were subsequently treated in the intensive care unit. Patients who succumbed postoperatively during hospitalization were defined as non-survivors. Serum ACE2 levels were measured in all patients prior to and following the surgery using ELISA kits. The results indicated that non-survivors showed significantly lower mean preoperative and postoperative serum ACE2 levels when compared with those in survivors. Multivariate logistic regression analysis also showed that, subsequent to adjusting for potential confounders, the serum ACE2 level on preoperative day 1 showed a significant negative association with the postoperative in-hospital mortality. This was confirmed by multivariate hazard ratio analysis, which showed that, subsequent to adjusting for the various potential confounders, the risk of postoperative in-hospital mortality remained significantly higher in the two lowest serum ACE2 level quartiles compared with that in the highest quartile on preoperative day 1. In conclusion, the present study provided the first evidence supporting that the serum ACE2 level is an independent risk factor for the in-hospital mortality following OSR for ruptured AAA. Furthermore, low serum ACE2 levels on preoperative day 1 were found to be associated with increased postoperative in-hospital mortality. Therefore, the serum ACE2 level on preoperative day 1 may be a potential

    Background Axillary web syndrome (AWS) is a condition that may develop following breast cancer surgery and that presents as a palpable axillary cord of tissue. Objective The purposes of this study were: (1) to determine the clinical characteristics of AWS related to movement, function, pain, and postoperative edema and (2) to define the incidence of and risk factors for AWS within the first 3 months following breast cancer surgery. Design This was a prospective cohort study with a repeated-measures design. Methods Women who underwent breast cancer surgery with sentinel node biopsy or axillary lymph node dissection (N=36) were assessed for AWS, shoulder range of motion, function, pain, and postoperative edema (using girth measurements, bioimpedance, and tissue dielectric constant) at 2, 4, and 12 weeks. Demographic characteristics were used for risk analysis. Results Seventeen women (47.2%) developed AWS, and AWS persisted in 10 participants (27.8%) at 12 weeks. Abduction range of motion was significantly lower in the AWS group compared with the non-AWS group at 2 and 4 weeks. There were no differences between groups in measurements of function, pain, or edema at any time point. Trunk edema measured by dielectric constant was present in both groups, with an incidence of 55%. Multivariate analysis determined lower body mass index as being significantly associated with AWS (odds ratio=0.86; 95% confidence interval=0.74, 1.00). Limitations Limitations included a short follow-up time and a small sample size. Conclusion Axillary web syndrome is prevalent following breast/axilla surgery for early-stage breast cancer and may persist beyond 12 weeks. The early consequences include movement restriction, but the long-term effects of persistent AWS cords are yet unknown. Low body mass index is considered a risk factor for AWS. PMID:25977305

    This study comprises a total of 141 patients with suspected primary and recurrent colorectal carcinomas, in whom immunoscintigraphy with 99mTc-Mab BW 431/26 was performed. Whole-body scans were done 5.5 hr and SPECT imaging of the abdominal region was done at 6 and 24 hr postinjection of 1100 MBq 99mTc-labeled Mab (1 mg). In the course of primary tumor identification (n = 65), sensitivity of anti-CEA immunoscintigraphy was 95%, specificity 91%. In the diagnosis of early recurrences (n = 76), immunoscintigraphy was the method of choice to clarify the problem (sensitivity 94%; specificity 86%). Overall sensitivity of immunoscintigraphy in patients with suspected colorectal carcinomas and early recurrences was 95%, specificity 88%. Human anti-mouse antibodies were found in 29% (80% predominantly anti-isotypic, 20% predominantly anti-idiotypic). In contrast to anti-CEA immunoscintigraphy, the results of serum CEA levels were rather disappointing. Only 18 out of the 43 surgically verified primary colorectal carcinomas and 17 out of 32 patients with recurrences showed elevated serum CEA levels. In our clinical experience with this 99mTc-labeled anti-CEA antibody, immunoscintigraphy can play an important role in the identification of early colorectal recurrences and in postoperative colorectal cancer patients it should be performed in cases with unclear transmission computed tomography.

    Low values for serum alkaline phosphatase activity were observed early in the course of two patients with Wilson's disease presenting with the combination of severe liver disease and Coombs' negative acute hemolytic anemia. A review of other cases of Wilson's disease revealed that 11 of 12 patients presenting with hemolytic anemia had values for serum alkaline phosphatase less than their respective sex- and age-adjusted mean values; in eight, serum alkaline phosphatase activity was less than the lower value for the normal range of the test. Low values for serum alkaline phosphatase were much less common in Wilson's disease patients with more chronic forms of presentation. Copper added in high concentration to serum in vitro did not have an important effect on serum alkaline phosphatase activity. The mechanism responsible for the decrease in serum alkaline phosphatase activity in patients is uncertain.

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

    The records of 70 patients with oral cancer who were treated at a single institution between 2008 and 2014 were reviewed. The body temperature, white blood cell count, and C-reactive protein (CRP) levels were compared between those who had received preoperative oral care (oral care group) and those who had not received any (non-oral care group). When the patients were divided into those who underwent minimally invasive surgery and those who underwent severely invasive surgery, the mean CRP level in the early postoperative period was lower in the oral care group as compared with the non-oral care group in those who underwent minimally invasive surgery as well as those who underwent severely invasive surgery. However, the mean CRP level was most evidently reduced in the severely invasive group on days 1 and 3–5. However, no significant differences were observed with regard to the percentage of postoperative infectious complications (for example, surgical site infection, anastomotic leak and pneumonia) between the oral care (13.6%) and non-oral care (20.8%) groups, though a reduced prevalence of postoperative complications following preoperative oral care was noted. The results of the present study suggest that preoperative oral care can decrease inflammation during the early postoperative stage in patients with oral cancer who undergo severely invasive surgery.

    Introduction and Objective. The Nuss procedure is widely used in the treatment of pectus excavatum worldwide. Postoperative pectus bar infection is one of the most serious complications associated with this procedure. Therefore, early detection of signs of implant infection is very important. However, this is difficult, and effective methods have yet to be established. Methods. We use a handheld infrared thermal imaging camera to screen patients for postoperative infection following the Nuss procedure. Here, we report a 28-year-old man with recurrent postoperative (Ravitch procedure) pectus excavatum. Results. Infrared thermography camera clearly indicated slight cellulitis in the right chest. Conclusion. Our technique may assist in preventing postoperative bar infection and removal caused by severe bar infection. Furthermore, this camera is potentially suitable for many situations in infection monitoring following subcutaneous implant surgery.

    Living-donor liver transplantation has provided a solution to the severe lack of cadaver grafts for the replacement of liver afflicted with end-stage cirrhosis, fulminant disease, or inborn errors of metabolism. Vascular complications remain the most serious complications and a common cause for graft failure after hepatic transplantation. Doppler ultrasound remains the primary radiological imaging modality for the diagnosis of such complications. This article presents a brief review of intra- and post-operative living donor liver transplantation anatomy and a synopsis of the role of ultrasonography and color Doppler in evaluating the graft vascular haemodynamics both during surgery and post-operatively in accurately defining the early vascular complications. Intra-operative ultrasonography of the liver graft provides the surgeon with useful real-time diagnostic and staging information that may result in an alteration in the planned surgical approach and corrections of surgical complications during the procedure of vascular anastomoses. The relevant intra-operative anatomy and the spectrum of normal and abnormal findings are described. Ultrasonography and color Doppler also provides the clinicians and surgeons early post-operative potential developmental complications that may occur during hospital stay. Early detection and thus early problem solving can make the difference between graft survival and failure. PMID:27468207

The aim of the study was to analyse preoperative, intraoperative and postoperative factors and their relationships with the occurrence and duration of atrial fibrillation. METHODS One hundred and ninety-six patients with coronary heart disease (152 men, age 62.7 ± 10.1 years) underwent surgical revascularization. Extracorporeal circulation was used in 64 patients and minimal extracorporeal circulation was used in 75 patients. Fifty-seven patients underwent surgery without extracorporeal circulation. During the first three postoperative days, subjects were monitored for the duration and incidence of atrial fibrillation, laboratory markers of inflammation (C-reactive protein, leucocytes) and serum potassium. RESULTS Demographic data and associated cardiovascular diseases in the groups were not statistically different. The overall incidence of atrial fibrillation was 56% (110 patients). The highest incidence of atrial fibrillation was found in the extracorporeal circulation subgroup, with a significantly lower incidence using minimal extracorporeal circulation, and in patients operated on without extracorporeal circulation (75 vs 47 vs 46%, P <0.001). The longest duration of atrial fibrillation was found in patients operated on with extracorporeal circulation compared with minimal extracorporeal circulation, and without extracorporeal circulation (9.7 ± 11.6 vs 4.9 ± 8.3 vs 3.1 ± 5.2, P ≤0.001). The incidence of postoperative atrial fibrillation significantly correlated with elevation of inflammatory markers (C-reactive protein, leucocytes) compared with patients who were free of atrial fibrillation (P ≤0.001, P ≤0.05). The values of serum potassium were not significantly different. The relationship between postoperative atrial fibrillation and echocardiographic parameters was not confirmed

    We report a case of pneumothorax revealed by postoperative computed tomography. A 39-year-old obese woman (height 153 cm, weight 70 kg) with fractures of the radius, ulna, clavicle, and femur in a traffic accident, was scheduled for osteosynthesis. Anesthesia was induced with thiopental and maintained with 50% nitrous oxide in oxygen and sevoflurane. The Spo2 decreased from 99% to 94% during the surgery. Bilateral chest sounds were symmetrical. The Spo2 increased to 100% after discontinuation of nitrous oxide. Pneumothorax was not evident on a postoperative chest X-ray, but computed tomography of the chest demonstrated right-sided pneumothorax. An ECG electrode had overlapped the fractured rib on the preoperative chest X-ray.

    Pulmonary complications are a major cause of morbidity and mortality in the post-operative period after thoracotomy. The type of complications and the severity of complications depend on the type of thoracic surgery that has been performed as well as on the patient's pre-operative medical status. Risk stratification can help in predicting the possibility of the post-operative complications. Certain airway complications are more prone to develop with thoracic surgery. Vocal cord injuries, bronchopleural fistulae, pulmonary emboli and post-thoracic surgery non-cardiogenic pulmonary oedema are some of the unique complications that occur in this subset of patients. The major pulmonary complications such as atelectasis, bronchospasm and pneumonia can lead to respiratory failure. This review was compiled after a search for search terms within ‘post-operative pulmonary complications after thoracic surgery and thoracotomy’ on search engines including PubMed and standard text references on the subject from 2000 to 2015.

    Studies of the serum bactericidal system in bovine brucellosis were undertaken to investigate the role of the humoral immune response in protection of cattle against the facultative intracellular parasite Brucella abortus. Fresh sera from normal control cattle, infected cattle, and cattle immunized with B. abortus cell envelopes were collected before treatment and during the course of immunization or infection. Normal fresh bovine serum or fresh agammaglobulinemic serum from colostrum-deprived calves was effective in killing smooth virulent B. abortus 2308, but rough strains RB51 (a rough mutant of strain 2308) and 45/20 were much more sensitive to serum. The difference in susceptibility to serum was shown to be correlated with differences in lipopolysaccharide chemotype, with the more resistant strain 2308 having O polysaccharide and the more susceptible strains 45/20 and RB51 lacking O side chains. By treatment of fresh serum with MgCl2 and EGTA [ethylene glycol-bis(beta-aminoethyl ether)-N,N,N',N'-tetraacetic acid] killing was shown to occur via the classical pathway of complement activation. When antibody to B. abortus was present, killing of strain RB51 increased but killing of smooth strain 2308 decreased. The earliest antibody response in serum from infected animals did not interfere with killing. When affinity-purified bovine immunoglobulins specific for B. abortus smooth lipopolysaccharide were added to fresh normal bovine serum, immunoglobulin G1 (IgG1) and IgG2 isotypes blocked killing but IgM and IgA isotypes did not. Thus, it appears that serum from previously unexposed animals or animals early during infection can kill smooth B. abortus, an appropriate defense mechanism before the organism becomes intracellular. At later stages of infection, blocking antibodies predominate.

    Introduction Risk factors associated with Carpal Tunnel Syndrome include repetitive use of hand and wrist, advanced age, obesity, pregnancy, diabetes mellitus and thyroid disease. Decompression of the median nerve is the last treatment of choice usually indicated when negative results to conservative treatments remain for three months. In this study, we aimed to find out whether hypothyroid patients would respond to CTS surgical decompression differently in comparison to healthy individuals. Methods This case control study was conducted on patients with CTS in need of surgical release who were refered to Shahid Faghihi hospital, International Branch of Shiraz University of Medical Sciences, Shiraz, Iran from January 2013 to January 2015. Twenty-five hypothyroid and 22 euthyroid patients were recruited. Hypothyroidism was diagnosed based on clinical symptoms and serum TSH level. All patients were followed for three weeks after surgery and a Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) was completed for them pre and post operation. An electrophysiological study was performed during the same follow up period. Statistical analysis was performed using SPSS version 16. Results The CTS grade reported by electrophysiological study, decreased significantly 3 weeks after operation in comparison with preoperative grades (p<0.001). A significant decrease was observed in the immediate postoperative BCTQ scores compared to preoperative (p<0.001). Also a decrease was detected in the three weeks of postoperative follow up compared to immediate postoperative BCTQ scores (p<0.001) and preoperative BCTQ scores (p<0.001). Postoperative BCTQ scores of euthyroid patients decreased more in comparison to hypothyroid patients (p<0.001). Conclusion It seems that, hypothyroidism has an effect on postoperative outcome of carpal tunnel release. PMID:27790353

    Glioblastoma multiforme (GBM) has associated with it one of the poorest prognoses among brain tumors. Postoperative seizures and the side effects of anticonvulsants, routinely given for prophylactic purposes, add to patient morbidity. The primary goal of this study was to determine who, of those undergoing craniotomy for GBM resection, is at risk for epilepsy. We studied 72 consecutive patients who underwent craniotomy and palliative resection for GBM. Twenty-nine presented with seizures and 17 had postoperative seizures. All patients were treated with a postoperative anticonvulsant for at least six months; anticonvulsants were continued longer if there was a postoperative seizure. Patient factors examined for an association with risk for postoperative seizure included age, sex, tumor size, tumor location, adjuvant therapy, postoperative complications and history of preoperative seizures. The majority of patients with no prior seizure history and who seized postoperatively had their first seizure after withdrawal from their anticonvulsant medication. All, but one, of the patients with both pre- and postoperative seizures had their first postoperative seizure while still on anticonvulsants. Smaller tumor size and frontal resection were associated with an increased risk of postoperative seizures. Our data suggests that those who do not present with seizures and undergo GBM resection may still be prone to seize but more easily protected from postoperative seizures with anticonvulsant therapy than patients who present with seizures; resection of frontal tumors and smaller tumors seemed to indicate an increased risk for postoperative seizures.

    Two hundred consecutive patients admitted for general surgery were studied prospectively to evaluate the contribution of risk factors to postoperative respiratory morbidity (PORM). PORM was expressed both in terms of individual clinical features present on the second postoperative day (when the incidence was greatest), and as an aggregate score incorporating many clinical features. The importance of recognised risk factors, such as previous respiratory disease, cigarette smoking, upper abdominal procedures and the duration of surgery was confirmed, in that these factors were associated with some of the individual clinical features of PORM. The relative importance and independent contribution of these risk factors were assessed by their association with the aggregate score. A naso-gastric tube (NGT) present for 24 hours postoperatively was the factor more associated with PORM. The NGT identified patients at risk more clearly than, and independently of, the next most important factor, upper abdominal surgery. The duration of surgery did not contribute to PORM after the influence of NGT and site of surgery had been considered. Previous respiratory disease predisposed to PORM, and was best identified by, in order of importance, an observed productive cough, a reduced one second forced expiratory volume, and purulent sputum. After the incidence of these factors had been considered, cigarette smoking and a history of a chronic productive cough did not contribute further to PORM. PMID:6952867

    Purpose To report the first case to our knowledge of intravitreal daptomycin used to successfully treat culture-negative vancomycin resistant to exogenous endophthalmitis. Methods Case report with preoperative, intraoperative, and postoperative findings. Results A 63-year-old Caucasian male underwent routine pars plana vitrectomy with epiretinal membrane peeling. He developed acute postoperative endophthalmitis, and underwent vitreous tap and injection of intravitreal vancomycin/ceftazidime/dexamethasone. Gram stain showed Gram-positive cocci, but cultures were negative. His infection subsequently proved very recalcitrant and his treatment course involved pars plana vitrectomy with anterior chamber washout and repeat injection of antibiotics, followed by repeat intravitreal vancomycin and ceftazidime. Ultimately, a second vitrectomy with intravitreal daptomycin controlled his intraocular infection. On each occasion, cultures were negative. Conclusion This case suggests that vancomycin resistance should be considered in culture-negative postoperative endophthalmitis, and intravitreal daptomycin should be considered as an important treatment alternative. Although vancomycin resistance is fairly rare in endophthalmitis, acknowledgment of its increasing occurrence rate is critical for optimal management. PMID:27293409

    Introduction: The incidence of malnutrition in hospitalized patients is reported to be high. In particular, patients with esophageal cancer are prone to malnutrition, due to preoperative digestive system dysfunctions and short-term non-oral feeding postoperatively. Selection of an appropriate method for feeding in the postoperative period is important in these patients. Materials and Methods: In this randomized clinical trial, 40 patients with esophageal cancer who had undergone esophagectomy between September 2008 and October 2009 were randomly assigned into either enteral feeding or parenteral feeding groups, with the same calorie intake in each group. The level of serum total protein, albumin, prealbumin, transferrin, C3, C4 and hs-C-reactive protein (hs-CRP), as well as the rate of surgical complications, restoration of bowel movements and cost was assessed in each group. Results: Our results showed that there was no significant difference between the groups in terms of serum albumin, prealbumin or transferrin. However, C3 and C4 levels were significantly higher in the enteral feeding group compared with the parenteral group, while hs-CRP level was significantly lower in the enteral feeding group. Bowel movements were restored sooner and costs of treatment were lower in the enteral group. Postoperative complications did not differ significantly between the groups. There was one death in the parenteral group 10 days after surgery due to myocardial infarction. Conclusion: The results of our study showed that enteral feeding can be used effectively in the first days after surgery, with few early complications and similar nutritional outcomes compared with the parenteral method. Enteral feeding was associated with reduced inflammation and was associated with an improvement in immunological responses, quicker return of bowel movements, and reduced costs in comparison with parenteral feeding.

    The serum bactericidal test represents one of the few in vitro tests performed in the clinical microbiology laboratory that combines the interaction of the pathogen, the antimicrobial agent, and the patient. Although the use of such a test antedates the antimicrobial era, its performance, results, and interpretation have been subject to question and controversy. Much of the confusion concerning the serum bactericidal test can be avoided by an understanding of the various factors which influence bactericidal testing. In addition, the methodologic aspects of the serum bactericidal test have recently been addressed and should place this test on firmer ground. New information on the clinical utility of this test is becoming available; additional data are needed to establish more clearly the usefulness of the serum bactericidal test in specific infections. Such clinical trials from multiple centers will enable firmer recommendations for the future use of the serum bactericidal test. PMID:3060242

    The aim of this study is to evaluate the changes in serum sodium concentration and the degree of correlation with factors such as the amount of intravenous fluid intake, the kind and the amount of irrigating fluids and the duration of the procedure. In this framework, 98 male patients who underwent transurethral procedure were studied and the correlation between the magnitude of hyponatraemia and the above-mentioned parameters was evaluated. All procedures were performed under spinal anesthesia and a solution of either manitol-sorbitol or sterilized water was used as irrigation fluid. Serum sodium concentration was measured before and after the procedure, while the kind and amount of the irrigating fluids, the amount of fluid intake and the duration of the procedure were also recorded. The patients were divided into three groups according to the duration of the procedure (i) <30 min, (ii) 30-60 min, and (iii) >60 min. Significant reduction in serum sodium concentration was found postoperatively (P < 0.001) and this was more profound in procedures longer than 1 h. This reduction was strongly correlated only with the duration of the transurethral procedure (P < 0.01). In conclusion, in transurethral procedures the reduction in serum sodium is postoperatively related to the duration of the procedure, while the intravenous and irrigating fluids to play no role on it.

    Local anesthetic infiltration has been proposed to decrease postoperative pain. The aim of this study was to determine whether scalp infiltration with bupivacaine or ropivacaine would improve analgesia after supratentorial craniotomy for tumor resection. Eighty patients were recruited into a randomized double-blind study. Infiltration was performed after skin closure with 20 mL of saline 0.9% (placebo group, n = 40), of 0.375% bupivacaine with epinephrine 1:200,000 (bupivacaine group, n = 20), or of 0.75% ropivacaine (ropivacaine group, n = 20). Postoperative analgesia was provided with patient-controlled morphine IV analgesia (PCA). The study was continued until PACU discharge, which occurred early in the morning following surgery. Results are reported on 37 patients in the placebo group, 20 in the bupivacaine group, and 19 in the ropivacaine group because 4 patients experienced postoperative complications and were excluded from the study. Morphine titration at arrival in the postanesthesia care unit was necessary more often in the placebo group (62% of the patients) than in the 2 treated groups (19% in each, P = 0.02). The median quantity of morphine administered during the first 2 postoperative hours, including initial titration administered by a nurse and PCA-administered morphine, was lower in each treated group than in the placebo group (P < 0.01). The median morphine consumption up to the 16th postoperative hour was not significantly different among the 3 groups. There was no difference in the visual analogue scale scores among the 3 groups at any time. Scalp infiltration with either bupivacaine or ropivacaine had a statistically significant effect on morphine consumption during the first 2 postoperative hours. PMID:16037734

    To evaluate the kidney function after living kidney donation, we measured serum creatinine (SCr), cystatin C, and neutrophil gelatinase-associated lipocalin (NGAL) of 42 living donors before uninephrectomy and in three immediate days after it. We also evaluated the prevalence of the occurrence of the different stages of acute kidney injury (AKI) classified according to risk, injury, failure, loss, and end-stage (RIFLE) criteria, and accuracy of each of these three biomarkers for predicting them were evaluated. Significant serum NGAL (s-NGAL) changes were limited to the 1 st day after donation, whereas SCr and cystatin C changes continued to the third day after donation. s-NGAL level in the 1 st day and serum cystatin C in the 3 rd day after donation, respectively, had the largest area under curve and best sensitivity and specificity for Stage 1 (risk) AKI prediction. During the immediate three days after donation, about half of patients suffered from AKI; mostly Stage 1 (injury). The sequence of the emergence of s-NGAL and s-cystatin C in the 1 st and 3 rd days as biomarkers with highest accuracy and power for RIFLE criteria defined AKI stage discrimination in our study was comparable to previous studies. We conclude that our study suggests that AKI was best detected in the 1 st day after uninephrectomy by the s-NGAL levels, whereas cystatin C was the best in the 3 rd day after donation for detection of AKI.

    Background Antegrade cerebral perfusion (ACP) typically is used with deep hypothermia for cerebral protection during aortic arch reconstructions. The impact of ACP on cerebral oxygenation and serum creatinine at a more tepid 25 °C was studied in newborns and children. Methods Between 2010 and 2014, 61 newborns and children (<5 years old) underwent aortic arch reconstruction using moderate hypothermia (25.0±0.9 °C) with ACP and a pH-stat blood gas management strategy. These included 44% Norwood-type operations, 30% isolated arch reconstructions, and 26% arch reconstructions with other major procedures. Median patient age at surgery was 9 days (range, 3 days–4.7 years). Cerebral oxygenation (NIRS) was monitored continuously perioperatively for 120 hours. Serum creatinine was monitored daily. Results Median cardiopulmonary bypass (CPB) and cross clamp times were 181 minutes (range, 82–652 minutes) and 72 minutes (range, 10–364 minutes), respectively. ACP was performed at a mean flow rate of 46±6 mL/min/kg for a median of 48 minutes (range, 10–123 minutes). Cerebral and somatic NIRS were preserved intraoperatively and remained at baseline postoperatively during the first 120 hours. Peak postoperative serum creatinine levels averaged 0.7±0.3 mg/dL for all patients. There were 4 (6.6%) discharge mortalities. Six patients (9.8%) required ECMO support. Median postoperative length of hospital and intensive care unit (ICU) stay were 16 days(range, 4–104 days) and 9 days (range, 1–104 days), respectively. Two patients (3.3%) received short-term peritoneal dialysis for fluid removal, and none required hemodialysis. Three patients (4.9%) had an isolated seizure which resolved with medical therapy, and none had a neurologic deficit or stroke. Conclusions ACP at 25 °C preserved perioperative cerebral oxygenation and serum creatinine for newborns and children undergoing arch reconstruction. Early outcomes are encouraging, and additional study is warranted to

    This cross-sectional observational study was to establish the preoperative assessment of serum albumin level as indicator for morbidity following cancer surgery and to reduce the incidence of related postoperative complications. Therefore this study was undertaken to assess the morbidity associated with low serum level albumin and identify it as a risk factor following cancer surgery in Bangladeshi population. This study included 312 patients with malignancy who were waiting for surgery or within 60 days of postoperative period were enrolled for the study from indoor of surgical oncology department, National Institute of Cancer Research & Hospital (NICR&H), Dhaka, Bangladesh. Then the patients were submitted for further study to evaluate the preoperative fitness in terms of nutritional assessment - both clinical and biological especially serum albumin level. All the clinical (pre & post-operative including complication, if any), investigation findings were recorded accordingly. Statistical correlation was discovered between BMI and morbidity but no statistical correlation was found between WL >10% and major surgical complications of either infectious or noninfectious origin (p=NS). Conversely, a substantial statistical correlation was found between Hb% or albumin <30gm/l and major surgical complications (either infectious or noninfectious) (p<0.001). The serum albumin level below 30gm/l is a significant risk factor for oncological postoperative major complications (MC).

    Introduction There are many techniques which may be involved in abdominal hernia repair, from classical to tension-free. Treatment of complicated hernias has undergone evolution. Many surgeons consider the laparoscopic method as a method of choice for incisional hernia repair. Sometimes miniinvasive repair of complicated hernia is not so easy to perform. We are convinced that selected patients may benefit from combined open and laparoscopic techniques. Aim To present the operating technique and early results of treatment of 15 patients operated on using the 3 hybrid technique. Material and methods Fifteen patients suffering from recurrent incisional hernias underwent the hybrid technique for their repair between June 2012 and April 2015. The hybrid technique was performed using synthetic meshes in 14 cases and a biological implant in 1 case. Results The early postoperative period was uncomplicated in all cases. Within a maximum follow-up period of 32 months, two deep wound infections were observed. Conclusions The hybrid technique may be used in patients with recurrent incisional hernias. PMID:26865889

  18. Prevention and management of postoperative urinary retention after urogynecologic surgery

    Geller, Elizabeth J

    2014-01-01

    Postoperative urinary retention (POUR) is a frequent consequence of gynecologic surgery, especially with surgical correction of urinary incontinence and pelvic organ prolapse. Estimates of retention rates after pelvic surgery range from 2.5%–43%. While there is no standard definition for POUR, it is characterized by impaired bladder emptying, with an elevation in the volume of retained urine. The key to management of POUR is early identification. All patients undergoing pelvic surgery, especially for the correction of incontinence or prolapse, should have an assessment of voiding function prior to discharge. There are several ways to assess voiding function – the gold standard is by measuring a postvoid residual. Management of POUR is fairly straightforward. The goal is to decompress the bladder to avoid long-term damage to bladder integrity and function. The decision regarding when to discontinue catheter-assisted bladder drainage in the postoperative period can be assessed in an ongoing fashion by measurement of postvoid residual. The rate of prolonged POUR beyond 4 weeks is low, and therefore most retention can be expected to resolve spontaneously within 4–6 weeks. When POUR does not resolve spontaneously, more active management may be required. Techniques include urethral dilation, sling stretching, sling incision, partial sling resection, and urethrolysis. While some risk of POUR is inevitable, there are risk factors that are modifiable. Patients that are at higher risk – either due to the procedures being performed or their clinical risk factors – should be counseled regarding the risks and management options for POUR prior to their surgery. Although POUR is a serious condition that can have serious consequences if left untreated, it is easily diagnosed and typically self-resolves. Clinician awareness of the condition and vigilance in its diagnosis are the key factors to successful care for patients undergoing surgical repair. PMID:25210477

    Background Research on post-transplant care has predominantly focused on predictors of readmission with little attention to emergency department (ED) visits. The goal of this study was to describe early postoperative ED care of transplant recipients. Methods A secondary database analysis of adult patients who underwent abdominal organ transplantation between January 1, 2008 and December 31, 2013 and sought ED care within one year post-transplantation was conducted. Survival was compared using the Kaplan-Meier method with log-rank test. Cox proportional hazards regression analysis was performed to adjust for pertinent covariates. Results A total of 1,900 abdominal organ transplants were performed during the study period. Of these, 37% (N=711) transplant recipients sought care in the ED (1,343 total visits) with 1.89 mean ED visits per recipient. Of recipients seen in the ED, 58% received a kidney transplant and 28% received a liver transplant, with 45% of recipients presenting within the first 60 postoperative days. The most common chief complaints were gastroenterological (17%) and abnormal laboratory values or vital signs (17%). In total, 74% of recipients were readmitted and 50% of admitted patients were discharged in less than 24 hours. Transplant recipients with ED visits had lower 3-year graft (81% vs. 87%; p<0.001) and patient (89% vs. 93%; p=0.002) survival. Conclusion Transplant recipients have a high frequency of ED visits in the first post-transplantation year and high rates of subsequent hospital admission. Further investigation is needed to understand what drives recipient presentation to the ED and create care models that achieve the best outcomes. PMID:26050012

    Objective: To obtain further analysis regarding specific outcomes and alvimopan doses in bowel resection (BR) patients. Summary Background Data: Although postoperative ileus (POI) is common after BR, there is currently no recognized treatment or prevention available. Alvimopan, a novel, peripherally active mu-opioid receptor antagonist, accelerated GI recovery after BR or hysterectomy in 3 phase III trials. Methods: A pooled retrospective subset analysis of BR patients in alvimopan phase III trials was performed. Randomized BR patients received alvimopan 6 mg (n = 397), 12 mg (n = 413), or placebo (n = 402) ≥2 hours before surgery and twice daily until hospital discharge for ≤7 days. The primary endpoint of each trial was time to recovery of GI function. Hospital discharge order (DCO) written, readmission, and morbidities were also assessed. Cox proportional hazard models were used to analyze treatment effects on time-to-event endpoints. Results: Alvimopan (6 or 12 mg) significantly accelerated GI recovery (GI-3; hazard ratio = 1.28 and 1.38, respectively; P ≤ 0.001 for both). Alvimopan significantly accelerated time to DCO written by 16 hours for 6 mg and 18 hours for 12 mg (P < 0.001 for both) from a mean of 147 hours for placebo. Alvimopan-treated patients had reduced postoperative morbidity compared with placebo, and incidence of prolonged hospital stay or readmission was significantly reduced (P < 0.001). Tolerability profiles were similar among groups. Conclusions: Alvimopan significantly accelerated GI recovery in BR patients. A 12-mg dose provided more consistent benefits across both sexes and all ages. Postoperative morbidity rates, prolonged hospital stay, and rates of hospital readmission were significantly reduced. Alvimopan reduces the consequences of POI after BR. PMID:17435541

This study investigates postoperative immunotherapy with CY as an alternate treatment for advanced immunogenic tumors such as neuroblastoma that typically respond poorly to traditional high-dose chemotherapy. A/J mice with 1.5-cm subcutaneous C1300-neuroblastoma (C1300-NB) tumors were divided into the following treatment groups: I, untreated (n = 14); II, 85% tumor resection (n = 18); III, sham-operated (n = 18); IV, multiple-dose CY (n = 6); V, 85% resection and single-dose CY (n = 14); VI, 85% resection and multiple-dose CY (n = 14). CY (100 mg/kg, intraperitoneally) was given initially 24 hours post-operatively to groups IV, V, and VI. Groups IV and VI also received weekly maintenance doses of 25 mg/kg CY. Results showed significantly increased survival (log-rank test) in CY-treated groups (IV, V, VI) compared with control groups (I,II,III). Cures were observed only in groups receiving partial resection plus CY (V, 7%; VI, 29%). Although surgical debulking of tumor alone (II) did not enhance survival, the procedure normalized depressed total lymphocyte counts and the subpopulation of Lyt 2,3+ (T suppressor/cytolytic cells) in the immediate postoperative period during which immunotherapy with CY was instigated. This may have contributed to the success of CY immunotherapy. To characterize the tumor-host immune interaction, additional studies were performed. Results showed the following. (1) Mice cured by debulking plus CY (from groups V and VI) could not be successfully reimplanted with C1300-NB, demonstrating immunologic mediation by CY.(ABSTRACT TRUNCATED AT 250 WORDS)

    A great deal of progress has been made in the field of postoperative pain therapy in the last 20 years. Beginning from clinical trials on the effectiveness of individual procedures, such as epidural anesthesia and patient-controlled analgesia, a wide range of healthcare services research as well as basic research with human and animal experiments has been established. Whereas health services research in the 1980s and 1990s focused more on the implementation of acute pain services, outcome-oriented research approaches are nowadays the center of attention. Acute pain registries and pain certification projects initiated in Germany have to be mentioned particularly in this respect. Basic research papers from recent years increasingly address specific aspects of acute postoperative pain and have provided translational approaches that are applied around the world for studying neurobiological mechanisms of postoperative pain. At the same time, interdisciplinary cooperation in research projects has led to a better understanding of complex correlations regarding predictors and mechanisms (including psychosocial aspects) of acute and in recent times also chronic pain after surgery. In parallel, evidence-based medicine has found its way into acute pain medicine in Germany. In 2007, clinical acute pain therapy in Germany was enhanced by S3 level guidelines for the first time; however, the implementation is still incomplete. In future, questions concerning mechanism-based therapy of acute pain need to be equally in the center of attention of research, such as prevention of persisting pain after surgery and acute pain of different origins.

    The aim of this study was to compare the analgesic efficacy of three different postoperative treatments after supratentorial craniotomy. Sixty-four patients were allocated prospectively and randomly into three groups: paracetamol (the P group, n = 8), paracetamol and tramadol (the PT group, n = 29), and paracetamol and nalbuphine (the PN group, n = 27). General anesthesia was standardized with propofol and remifentanil using atracurium as the muscle relaxant. One hour before the end of surgery, all patients received 30 mg/kg propacetamol intravenously then 30 mg/kg every 6 hours. Patients in the PT group received 1.5 mg/kg tramadol 1 hour before the end of surgery. For patients in the PN group, 0.15 mg/kg nalbuphine was injected after discontinuation of remifentanil, because of its mu-antagonist effect. Postoperative pain was assessed in the fully awake patient after extubation (hour 0) and at 1, 2, 4, 8, and 24 hours using a visual analog scale (VAS). Additional tramadol (1.5 mg/kg) or 0.15 mg/kg nalbuphine was administered when the VAS score was > or = 30 mm. Analgesia was compared using the Mantha and Kaplan-Meier methods. Adverse effects of the drugs were also measured. The three groups were similar with respect to the total dose of remifentanil received (0.27 +/- 0.1 mircog/kg/min). In all patients, extubation was obtained within 6 +/- 3 minutes after remifentanil administration. Postoperative analgesia was ineffective in the P group; therefore, inclusions in this group were stopped after the eighth patient. Postoperative analgesia was effective in the two remaining groups because VAS scores were similar, except at hour 1, when nalbuphine was more effective (P = .001). Nevertheless, acquiring such a result demanded significantly more tramadol than nalbuphine (P < .05). More cases of nausea and vomiting were observed in the PT group but the difference was not significant (P < .06). In conclusion, pain after supratentorial neurosurgery must be taken into account

    Postoperative endophthalmitis is an uncommon complication of cataract surgery with grave consequences. This report describes the trend of endophthalmitis in a district general hospital in England over eight years, and attempts made to modify this trend. An outbreak of endophthalmitis in 2007 led to a detailed investigation and subsequent changes in practice. Intracameral cefuroxime (ICC) was introduced in place of subconjunctival cefuroxime. Use of ICC in patients with 'penicillin allergy' was explored, found to be safe and resulted in a change of policy. This led to a four-fold reduction in the rate of endophthalmitis.

    Bladder exstrophy is a rare malformation characterized by an infra-umbilical abdominal wall defect, incomplete closure of the bladder with mucosa continuous with the abdominal wall, epispadias, and alterations in the pelvic bones and muscles. It is part of the exstrophy-epispadias complex, with cloacal exstrophy on the severe and epispadias on the mild ends of the spectrum. Bladder exstrophy is the most common of these entities and is more common in boys. The goal of this paper is to describe common methods of repair and to provide an imaging review of the postoperative appearances. PMID:24939762

    Formation of heterotopic bone (HTB) following total hip replacement may partially or completely ankylose the joint space, causing pain and/or limiting the range of motion. Patients at high risk for formation of HTB postoperatively include those with previous HTB formation, heterotopic osteoarthritis, and active rheumatoid spondylitis. Patients in these high risk groups have a 63-69% incidence of post-operative HTB formation, usually seen radiographically by 2 months post-operation. From 1980-1986 twenty-nine hips in 28 consecutively treated patients were irradiated post-operatively at the UCLA Center for the Health Sciences. The indication for irradiation was documented HTB formation previously in 26 of the 27 hips presented below. From 1980-1982 patients received 20 Gray (Gy) in 2 Gy fractions; from 1982-1986 the dose was reduced to 10 Gy in 2 Gy fractions. Twenty-seven hips in 26 patients completed therapy and were available for evaluation, with a minimum of 2 month follow-up, and a median follow-up of 12 months. Three of 27 hips developed significant HTB (Brooker grade III or IV) post-operatively, whereas 5 of 27 hips developed minor, nonsymptomatic HTB (Brooker grade I). When irradiation was begun by postoperative day 4, 0 of 17 hips formed significant HTB. If irradiation began after post-operative day 4, 3 of 10 hips formed significant HTB (Brooker grade III or IV). These 3 hips received doses of 10 Gy in one hip and 20 Gy in the other 2 hips. There were no differences in the incidence or severity of side effects in the 10 Gy vs. the 20 Gy treatment groups. Eighteen hips received 10 Gy, 8 hips 20 Gy and, 1 hip 12 Gy. In conclusion, 10 Gy in 5 fractions appears as effective as 20 Gy in 10 fractions at preventing post-operative formation of HTB. For optimal results, treatment should begin as early as possible prior to post-operative day 4.

  8. Postoperative Arrhythmias after Cardiac Surgery: Incidence, Risk Factors, and Therapeutic Management

    Arrhythmias are a known complication after cardiac surgery and represent a major cause of morbidity, increased length of hospital stay, and economic costs. However, little is known about incidence, risk factors, and treatment of early postoperative arrhythmias. Both tachyarrhythmias and bradyarrhythmias can present in the postoperative period. In this setting, atrial fibrillation is the most common heart rhythm disorder. Postoperative atrial fibrillation is often self-limiting, but it may require anticoagulation therapy and either a rate or rhythm control strategy. However, ventricular arrhythmias and conduction disturbances can also occur. Sustained ventricular arrhythmias in the recovery period after cardiac surgery may warrant acute treatment and long-term preventive strategy in the absence of reversible causes. Transient bradyarrhythmias may be managed with temporary pacing wires placed at surgery, but significant and persistent atrioventricular block or sinus node dysfunction can occur with the need for permanent pacing. We provide a complete and updated review about mechanisms, risk factors, and treatment strategies for the main postoperative arrhythmias. PMID:24511410

    Aims To determine the comparative efficacy of a new novel adenosine agonist (WAG 994) in postoperative pain after third molar surgery. Methods One hundred and twenty-two patients with postoperative pain after third molar surgery were randomised in a placebo double-blind trial with an active control group. In the early postoperative period patients received either a single dose of WAG 994 1 mg, ibuprofen 400 mg or matched placebos. Pain intensity score was recorded on serial visual analogue scales over a 6 h investigation period. Similarly, pain relief was completed on a 4 point categorical scale at each evaluation point. Patients had access to escape analgesic and if these were taken, the time and dosage were recorded. A sparse sampling technique was used to investigate the relationship between analgesic effects and plasma concentrations of WAG 994. Results All three treatment groups were matched for various demographic variables. For all efficacy measures, WAG 994 was not significantly different from placebo (P > 0.05), whereas ibuprofen 400 mg was significantly superior to placebo (P < 0.001). No significant relationships (P < 0.05) were found between WAG 994 pharmacokinetic variables and efficacy measures. Conclusion WAG 994, an adenosine agonist, did not show efficacy in the management of postoperative pain after third molar surgery. Although this pain responds well to nonsteroidal anti-inflammatory drugs, it appears to be resistant to compounds that interact with purinergic receptors. PMID:10383546

    Postoperative cognitive dysfunction (POCD) is a common complication after surgery, especially for elderly patients. Administration of RNase has been reported to exhibit neuroprotective effects in acute stroke. However, the potential role of RNase on POCD is unknown. Therefore, we sought to investigate whether RNase treatment could mitigate unilateral nephrectomy induced-cognitive deficit in aged mice. In the present study, twelve-month-old mice were administered RNase or an equal amount of normal saline perioperatively. All mice underwent Morris Water Maze (MWM) training 3 times per day for 7 days to acclimatize them to the water maze before surgical operation, and testing on days 1, 3 and 7 after surgery. We found that perioperative administration of RNase: 1) attenuated unilateral nephrectomy-induced cognitive impairment at day 3 after surgery; 2) reduced the hippocampal cytokines mRNA production and serum cytokines protein production at day 1 and day 7 (for MCP-1) after surgery, and; 3) inhibited hippocampal apoptosis as indicated by cleaved caspase-3 western blot and TUNEL staining at day 1 after surgery. In addition, a trend decrease of total serum RNA levels was detected in the RNase treated group after surgery compared with the untreated group. Further, our protocol of RNase administration had no impact on the arterial blood gas analysis right after surgery, kidney function and mortality rate at the observed days postoperatively. In conclusion, perioperative RNase treatment attenuated unilateral nephrectomy-induced cognitive impairment in aged mice. PMID:26225860

    This study aims to evaluate the viability of a clinical model of remote ischemic preconditioning (RIPC) and its analgesic effects. It is a prospective study with twenty (20) patients randomly divided into two groups: control group and RIPC group. The opioid analgesics consumption in the postoperative period, the presence of secondary mechanical hyperalgesia, the scores of postoperative pain by visual analog scale, and the plasma levels interleukins (IL-6) were evaluated. The tourniquet applying after spinal anesthetic block was safe, producing no pain for all patients in the tourniquet group. The total dose of morphine consumption in 24 hours was significantly lower in RIPC group than in the control group (p = 0.0156). The intensity analysis of rest pain, pain during coughing and pain in deep breathing, showed that visual analogue scale (VAS) scores were significantly lower in RIPC group compared to the control group: p = 0.0087, 0.0119, and 0.0015, respectively. There were no differences between groups in the analysis of presence or absence of mechanical hyperalgesia (p = 0.0704) and in the serum levels of IL-6 dosage over time (p < 0.0001). This clinical model of remote ischemic preconditioning promoted satisfactory analgesia in patients undergoing conventional cholecystectomy, without changing serum levels of IL-6. PMID:27446611

    Alzheimer's disease (EOAD, LOAD), mild cognitive impairment (MCI), Parkinson's disease (PD) and healthy controls were included to determine the serum interleukin-1s (IL-1α, IL-1β), IL-6 and alpha-2-macroglobulin (α2M) levels using ELISA. IL-6 might be a significant contributor to the inflammatory response in LOAD. The MCI data indicate that IL-1s, α2M and BDNF are somehow related, and this relationship might allow MCI patients to be more similar to the healthy controls. A correlation analysis of multiple biomarkers in different neurodegenerative disorders might be more useful than determining the levels of a single cytokine in a single disorder.

    Introduction Patient management following elective cranial surgery often includes routine postoperative computed tomography (CT). We analyzed whether a regime of early extubation and close neurological monitoring without routine CT is safe, and compared the rate of postoperative emergency neurosurgical intervention with published data. Methods Four hundred ninety-two patients were prospectively analyzed; 360 had supra- and 132 had infratentorial lesions. Extubation within one hour after skin closure was aimed for in all cases. CT was performed within 48 hours only in cases of unexpected neurological findings. Results Four-hundred sixty-nine of the 492 patients (95.3%) were extubated within one hour, 20 (4.1%) within 3 hours, and three (0.6%) within 3 to 10 hours. Emergency CT within 48 hours was performed for 43/492 (8.7%) cases. Rate of recraniotomy within 48 hours for patients with postoperative hemorrhage was 0.8% (n = 4), and 0.8% (n = 4) required placement of an external ventricular drain (EVD). Of 469 patients extubated within one hour, 3 required recraniotomy and 2 required EVD placements. Of 23 patients with delayed extubation, 1 recraniotomy and 2 EVDs were required. Failure to extubate within one hour was associated with a significantly higher risk of surgical intervention within 48 hours (rate 13.0%, p = 0.004, odds ratio 13.9, 95% confidence interval [3.11–62.37]). Discussion Early extubation combined with close neurological monitoring is safe and omits the need for routine postoperative CT. Patients not extubated within one hour do need early CT, since they had a significantly increased risk of requiring emergency neurosurgical intervention.

    Background This paper describes a randomized prospective study conducted in 308 patients undergoing caesarean section in spinal anaesthesia at a single hospital between 2010 and 2012 to find a suitable anti-emetic strategy for these patients. Material/Methods Spinal anesthesia was performed in left prone position, at L3/L4 with hyperbaric 0.5% Bupivacaine according to a cc/cm body height ratio. There were no opioids given peri-operatively. The patients received either no prophylaxis (Group I) or tropisetron and metoclopramide (Group II) or dimenhydrinate and dexamethasone (Group III), or tropisetron as a single medication (Group IV). The primary outcome was nausea and/or vomiting (NV) in the intraoperative, early (0–2 h) or late (2–24 h) postoperative period. Multivariate statistical analysis was conducted with a regression analysis and a backward elimination of factors without significant correlation. Results All prophylactic agents significantly reduced NV incidence intraoperatively. Relative risk reduction for NV by prophylaxis was most effective (59.5%) in Group II (tropisetron and metoclopramide). In Group III (dimenhydrinate and dexamethasone), NV risk was reduced by 29.9% and by 28.7% in Group IV (tropisetron mono-therapy). The incidence of NV in the early (0–2 h) and the late (2–24 h) postoperative period was low all over (7.8%), but the relative risk reduction of NV in the early postoperative period was 54.1% (Group IV), 45.1% (Group III), and 34.8% (Group II), respectively. In the late postoperative period, there was no significant difference between the 4 groups. Conclusions We recommend a prophylactic medication with tropisetron 2 mg and metoclopramide 20 mg for patients during caesarean section. These agents are safe, reasonably priced, and highly efficient in preventing nausea and vomiting. PMID:24226381

    1980-01-01

    Postoperative pain relief is only apparently an easy task. A brief survey of literature investigating the discomfort experienced in the postoperative phase is all but encouraging. One can identify four basic problems in obtaining adequate results by delivery of analgesic drugs: a) the biological variability among individual patients, b) the unpredictable uptake of the drug administered intramuscularly, c) the time lag involved between request by the patient and the subsequent administration of a single dose and d) the lack of knowledge about the nature of the discomfort and its remedies. An alternative strategy introducing "On-Demand" analgesia administering prescribed doses at the right moment is presented and analysed a) as an operant conditioning process implementing a particular reinforcement schedule (behavioural sciences), as well as b) a negative feedback control loop that entrust the central judgement to the patient (system theory). Both approaches give insight into the results: the technique copes with biological variability; anticipating pain induced by fear disappears; the feedback strategy works well and patients adapt to a wide range in prescriptions; intermittent administration makes more efficient use of the analgesic; an optimal result is demonstrated in studies comparing on-demand analgesia with the normal IM-regime and epidural analgesia; continuity in pain relief can be obtained in routine clinical practice.

    In 52 patients an indwelling transurethral catheter was inserted after gynaecological surgery for 5 days; no patient received antibiotics. At the time of removal of the catheter on the 6th postoperative day and 2 days later (8th postoperative day) a urine culture was set up. At the time of removal of the catheter on the 6th day, 26/52 patients (50%) had significant bacteriuria greater than or equal to 10(5)/ml. In 11 out of the 26 patients with bacteriuria the urine cleared spontaneously within 2 days; on the other hand, 10/26 patients with a negative culture at the time of removal of the catheter had significant bacteriuria 2 days later. As a group these women also had delayed spontaneous onset of voiding and persistence of residual urine. Younger patients (less than 45 years) had significantly fewer bacteriurias on the 6th day than older patients. A positive urine culture at the time of removal of the catheter should be treated with antibiotics; a negative urine culture should be repeated whenever spontaneous voiding is delayed, when there is persistent residual urine, or when the clinical signs of urinary tract infection are present.

    Background Although circumcision for phimosis in children is a minor surgical procedure, it is followed by pain and carries the risk of increased postoperative anxiety. This study examined predictive factors of postoperative pain and anxiety in children undergoing circumcision. Methods We conducted a prospective cohort study of children scheduled for elective circumcision. Circumcision was performed applying one of the following surgical techniques: sutureless prepuceplasty (SP), preputial plasty technique (PP), and conventional circumcision (CC). Demographics and base-line clinical characteristics were collected, and assessment of the level of preoperative anxiety was performed. Subsequently, a statistical model was designed in order to examine predictive factors of postoperative pain and postoperative anxiety. Assessment of postoperative pain was performed using the Faces Pain Scale (FPS). The Post Hospitalization Behavior Questionnaire study was used to assess negative behavioral manifestations. Results A total of 301 children with a mean age of 7.56 ± 2.61 years were included in the study. Predictive factors of postoperative pain measured with the FPS included a) the type of surgical technique, b) the absence of siblings, and c) the presence of postoperative complications. Predictive factors of postoperative anxiety included a) the type of surgical technique, b) the level of education of mothers, c) the presence of preoperative anxiety, and d) a history of previous surgery. Conclusions Although our study was not without its limitations, it expands current knowledge by adding new predictive factors of postoperative pain and postoperative anxiety. Clearly, further randomized controlled studies are needed to confirm its results. PMID:26495079

    Background: Considering the important role of pituitary gland in regulating various endocrine axes and its unique anatomical location, various postoperative complications can be anticipated resulting from surgery on pituitary tumors. We examined and categorized the immediate postoperative complications according to various tumor pathologies. Materials and Methods: We carried out a prospective study in 152 consecutive patients and noted various postoperative complications during neurosurgical intensive care unit stay (within 48 hrs of hospital stay) in patients undergoing transsphenoidal removal of pituitary tumors. Results: In our series, various groups showed different postoperative complications out of which, cerebrospinal fluid leak was the commonest followed by diabetes insipidus, postoperative nausea and vomiting, and hematoma at operation site. Conclusion: Various immediate postoperative complications can be anticipated in transsphenoidal pituitary surgery even though, it is considered to be relatively safe. PMID:25191182

    Study Design. Retrospective multivariate analysis of a prospectively collected, multi-center database.Objective. To identify patient characteristics and perioperative risk factors associated with postoperative infectious complications following single level lumbar fusion (SLLF) surgery.Summary of Background Data. Postoperative infection is a known complication following lumbar fusion. Risk factors for infectious complications following lumbar fusion have not been investigated using select set of SLLF procedures.Methods. Patients who underwent SLLF between 2006 and 2011 were identified from the American College of Surgeons National Surgical Quality Improvement Program database. Multivariate logistic regression analyses were performed to identify pre- and intra-operative risk factors associated with postoperative infection.Results. 3,353 patients were analyzed in this study. Overall, 173 (5.2%) patients experienced a postoperative infection, including 86 (2.6%) surgical site infections (SSI) and 111 (3.3%) non-SSI infectious complications (pneumonia, UTI, sepsis/septic shock). Twenty four (0.7%) patients experienced both SSI and non-SSI infectious complications. Postoperative SSI were associated with obesity (OR 1.628, 95% CI 1.042-2.544), American Society of Anesthesiologist (ASA) class>2 (OR 2.078, 95% CI 1.309-3.299), and operative time >6 hrs (OR 2.573, 95% CI 1.310-5.056). Risk factors for non-SSI infectious complications included age (60-69 yrs, OR 3.279, 95% CI 1.541-6.980;≥70 yrs, OR 3.348, 95% CI 1.519-7.378), female gender (OR 1.791, 95% CI 1.183-2.711), creatinine>1.5mg/dL (OR 2.400, 95% CI 1.138-5.062), ASA >2 (OR 1.835, 95% CI 1.177-2.860), and operative time >6hrs (OR 3.563, 95% CI 2.082-6.097).Conclusions. Across a wide study population, we identified that obesity, advanced ASA classification, and longer operative time were predictive of postoperative SSI. We also demonstrated that increased age, female gender, serum creatinine>1.5mg/dL, and

    Deep hypothermic circulatory arrest with cardiopulmonary bypass is indicated for complex surgical operations in adult patients involving the aortic arch, thoracoabdominal aorta, cerebral vasculature, and tumors extending into the vena cava and heart. Understanding the principles of ischemic-reperfusion injury and the effects of hypothermia in attenuating this process is fundamental to the delivery of effective postoperative care. Neurologic injury is the most troublesome adverse effect after the use of deep hypothermic circulatory arrest and cardiopulmonary bypass, presenting as either a transient neurologic deficit (5.9% to 28.1%) or an irreversible neurologic injury (1.8% to 13.6%). In patients with neurological injury, early postoperative mortality is markedly increased (18.2%), and for those patients that survive, long-term cognitive disability is still evident 6 months later. Early postoperative support of organ function, along with timely diagnosis and treatment of organ injury, is essential in minimizing perioperative morbidity, particularly neurologic morbidity. Meticulous management of fluids, maintaining stable cardiovascular hemodynamics with particular attention to systolic blood pressure, optimizing oxygen delivery, limiting ventilator-associated lung injury, intensive insulin therapy for control of blood glucose levels, and avoidance of hyperthermia are essential in limiting organ injury and reducing perioperative morbidity and mortality.

    Background Dipyrone (metamizole) is a non-steroidal anti-inflammatory drug used in some countries to treat pain (postoperative, colic, cancer, and migraine); it is banned in others because of an association with life-threatening blood agranulocytosis. This review updates a 2001 Cochrane review, and no relevant new studies were identified, but additional outcomes were sought. Objectives To assess the efficacy and adverse events of single dose dipyrone in acute postoperative pain. Search methods The earlier review searched CENTRAL, MEDLINE, EMBASE, LILACS and the Oxford Pain Relief Database to December 1999. For the update we searched CENTRAL, MEDLINE,EMBASE and LILACS to February 2010. Selection criteria Single dose, randomised, double-blind, placebo or active controlled trials of dipyrone for relief of established moderate to severe postoperative pain in adults. We included oral, rectal, intramuscular or intravenous administration of study drugs. Data collection and analysis Studies were assessed for methodological quality and data extracted by two review authors independently. Summed total pain relief over six hours (TOTPAR) was used to calculate the number of participants achieving at least 50% pain relief. Derived results were used to calculate, with 95% confidence intervals, relative benefit compared to placebo, and the number needed to treat (NNT) for one participant to experience at least 50% pain relief over six hours. Use and time to use of rescue medication were additional measures of efficacy. Information on adverse events and withdrawals was collected. Main results Fifteen studies tested mainly 500 mg oral dipyrone (173 participants), 2.5 g intravenous dipyrone (101), 2.5 g intramuscular dipyrone (99); fewer than 60 participants received any other dose. All studies used active controls (ibuprofen, paracetamol, aspirin, flurbiprofen, ketoprofen, dexketoprofen, ketorolac, pethidine, tramadol, suprofen); eight used placebo controls.

    Novel pharmaceutical advances in postoperative pain management include both non-opioid adjuvants as well as opioid analgesics. Optimizing postoperative analgesics includes improving onset of action, matching duration of analgesia to the setting of use, and minimizing adverse events. To improve on the current standard of care, the physicochemical properties of new analgesics and route of administration must be taken into consideration in order to achieve these three goals. Appropriately, patient satisfaction with postoperative pain is a key emphasis in hospital-focused patient satisfaction surveys, thereby focusing much-needed attention on improvement of care in the postoperative setting from both an analgesic efficacy and safety standpoint.

  8. Regulation of serum phosphate

    PubMed Central

    Lederer, Eleanor

    2014-01-01

    The regulation of serum phosphate, an acknowledged risk factor for chronic kidney disease and cardiovascular mortality, is poorly understood. The discovery of fibroblast growth factor 23 (FGF23) as a key regulator of renal phosphate handling and activation of vitamin D has revolutionized our comprehension of phosphate homeostasis. Through as yet undetermined mechanisms, circulating and dietary phosphate appear to have a direct effect on FGF23 release by bone cells that, in turn, causes renal phosphate excretion and decreases intestinal phosphate absorption through a decrease in vitamin D production. Thus, the two major phosphaturic hormones, PTH and FGF23, have opposing effects on vitamin D production, placing vitamin D at the nexus of phosphate homeostasis. While our understanding of phosphate homeostasis has advanced, the factors determining regulation of serum phosphate level remain enigmatic. Diet, time of day, season, gender, age and genetics have all been identified as significant contributors to serum phosphate level. The effects of these factors on serum phosphate have major implications for what is understood as ‘normal’ and for studies of phosphate homeostasis and metabolism. Moreover, other hormonal mediators such as dopamine, insulin-like growth factor, and angiotensin II also affect renal handling of phosphate. How the major hormone effects on phosphate handling are regulated and how the effect of these other factors are integrated to yield the measurable serum phosphate are only now beginning to be studied.

    2016-01-01

    Esophageal cancer is the sixth leading cause of cancer death worldwide, and patients who are treated with surgery alone, without neoadjuvant therapies, experience frequent relapses. Whether postoperative therapies could reduce the recurrence or improve overall survival is still controversial for these patients. The purpose of our review is to figure out the value of postoperative adjuvant therapy and address the disputes about target volume delineation according to published data. Based on the evidence of increased morbidity and disadvantages on patient survival caused by postoperative chemotherapy or radiotherapy (RT) alone provided by studies in the early 1990s, the use of postoperative adjuvant therapies in cases of esophageal squamous cell carcinoma has diminished substantially and has been replaced gradually by neoadjuvant chemoradiation. With advances in surgery and RT, accumulating evidence has recently rekindled interest in the delivery of postoperative RT or chemoradiotherapy in patients with stage T3/T4 or N1 (lymph node positive) carcinomas after radical surgery. However, due to complications with the standard radiation field, a nonconforming modified field has been adopted in most studies. Therefore, we analyze different field applications and provide suggestions on the optimization of the radiation field based on the major sites of relapse and the surgical non-clearance area. For upper and middle thoracic esophageal carcinomas, the bilateral supraclavicular and superior mediastinal areas remain common sites of recurrence and should be encompassed within the clinical target volume. In contrast, a consensus has yet to be reached regarding lower thoracic esophageal carcinomas; the “standard” clinical target volume is still recommended. Further studies of larger sample sizes should focus on different recurrence patterns, categorized by tumor locations, refined classifications, and differing molecular biology, to provide more information on the

    PubMed Central

    Ahuja, Vanita; Mitra, Sukanya; Sarna, Rashi

    2015-01-01

    Background and Aims: Post-operative sore throat (POST) occurs in 21-65% of patients. Ketamine used earlier as gargle for reducing POST has limitations. The aim of this study was to see if nebulised ketamine reduces POST. Methods: We conducted a prospective, randomised, placebo-control, and double-blind controlled trial. After written informed consent, 100 patients belonging to American Society of Anaesthesiologists physical status I-II in the age group 20-60 years, of either sex undergoing surgery under general anaesthesia (GA) were enrolled. Patients were randomised into two groups; group saline (S) received saline nebulisation 5.0 ml and group ketamine (K) received ketamine 50 mg (1.0 ml) with 4.0 ml of saline nebulisation for 15 min. GA was induced 10 min after completion of nebulisation in the patients. The POST and haemodynamic monitoring were done pre-nebulization, pre-induction, on reaching post-anaesthesia care unit, and at 2, 4, 6, 8, 12 and 24 h post-operatively. POST was graded on a four-point scale (0-3). Results: The overall incidence of POST was 33%; 23 patients (46%) in saline and 10 patients (20%) in ketamine group experienced POST (Fisher's exact P = 0.01). The use of ketamine nebulization attenuated POST at 2 h and 4 h post-operatively (P < 0.05). The primary outcome was incidence of POST at 4 h; 13 patients in group S versus 4 patients in group K (P = 0.03) experienced POST at 4 h. The moderate sore throat occurred in 6 patients in group S and none in group K at 2 h, post-operatively (P = 0.02). Conclusion: Ketamine nebulization significantly attenuated the incidence and severity of POST, especially in the early post-operative period, with no adverse effects. PMID:25684812

    Swelling or oedema of forehead or eyelids is a common consequence of hair transplantation surgery. However, this results in increased morbidity and absence from work due to unaesthetic appearance. To study various physical and therapeutic modalities to reduce or completely prevent the occurrence of such oedema. Three hundred forty hair transplant patients were recruited in the study and were categorized into 8 groups depending upon the intervention employed. There were 32 dropouts in the study due to various reasons. Patients who were administered steroid with tumescent solution had the highest number of patients without oedema, with only 3 out of 117 patients developing oedema. Physical measures like position of head during sleeping, application of occlusion bands or ice packs did not show satisfactory results. Addition of triamcinolone to tumescent anaesthetic solution is a very effective technique of preventing post-operative swelling. PMID:21031066

    The methods of providing postoperative analgesia by regional anaesthetic techniques with local anaesthetics are outlined. For the use of epidural analgesia, the techniques of inserting an epidural catheter at any level of the spine must be familiar. The block should be regional, restricted to the area of pain and effective at all times after its institution with a minimum of side effects. Bupivacaine is at present the best local anaesthetic and can be administered either as intermittent injections with an interval of 1-2 hours or as a continuous infusion. A dose regimen for thoracic, abdominal, perineal and lower extremity pain is presented. Side effects of the epidural technique and ways to treat and avoid them are discussed. The intercostal nerve block for post-thoracotomy and upper abdominal pain is described with special reference to the recent development of the continuous technique with bupivacaine and the cryoanalgesia technique.

    Intravenous administration of analgesic drugs is one of the most common ways to control post-operative pain. It can be used in almost all kinds of surgical interventions and particularly those of medium and high complexity. Besides, when other techniques are contraindicated because of clinical and/or managing problems, intravenous way finds its best application. Among analgesic drugs NSAID (ketorolac) and opioids (tramadol, morphine, buprenorphine) are most frequently used. As to administration techniques, elastomeric pump is, according to personal experience, a simple-to-manage, practical and precise device with lower cost respect to other administration set. Elastomeric pump is a single use reservoir that allows continuous administration of drugs with a uniform pre-set infusion speed. Finally, guide-lines, showing pre-load and infusion doses of analgesic drugs, based on pain intensity, are presented. PMID:14663417

    Wilk, Kevin E; Macrina, Leonard C

    2013-10-01

    The glenohumeral joint is an inherently unstable joint that relies on the interaction of the dynamic and static stabilizers to maintain stability. Disruption of this interplay or poor development of any of these factors may result in instability, pain, and a loss of function. Rehabilitation will vary based on the type of instability present and the key principles described. Whether a course of nonoperative rehabilitation is followed or the patient presents postoperatively, a comprehensive program designed to establish full ROM and balance capsular mobility, in addition to maximizing muscular strength, endurance, proprioception, dynamic stability, and neuromuscular control is essential. A functional approach to rehabilitation using movement patterns and sport-specific positions along with an interval sport program will allow a gradual return to athletics. The focus of the program should minimize the risk of recurrence and ensure that the patient can safely return to functional activities.

    According to the Diagnostic and Statistical Manual IV (DSM IV), conversion disorder is classified as a somatoform illness and defined as an alteration or loss of physical function because of the expression of an underlying psychological ailment. This condition, previously known as hysteria, hysterical neurosis, or conversion hysteria occurs rarely, with an incidence of 11-300 cases per 100,000 people (American Psychiatric Association. Diagnostic and statistical manual of mental disorders. 4th edn. Washington, DC: American Psychiatric Association, 1994). Presentation after an anesthetic is exceptional. After thorough review of the literature, fewer than 20 cases have been documented, with only two instances in patients younger than 18 years of age after general anesthesia; both were mild in nature. We present a severe case of postoperative conversion disorder that developed upon emergence from anesthesia in a previously healthy 16-year-old girl following direct laryngoscopy with vocal fold injection.

  18. Radiotherapy in the treatment of postoperative chylothorax

    PubMed Central

    2013-01-01

    Background Chylothorax is characterized by the presence of chyle in the pleural cavity. The healing rate of non-operative treatment varies enormously; the maximum success rate in series is 70%. We investigate the efficacy and outcomes of radiotherapy for postoperative chylothorax. Methods Chylothorax was identified based on the quantity and quality of the drainage fluid. Radiation was indicated if the daily chyle flow exceeded 450 ml after complete cessation of oral intake. Radiotherapy consisted of opposed isocentric portals to the mediastinum using 15 MV photon beams from a linear accelerator, a single dose of 1–1.5 Gy, and a maximum of five fractions per week. The radiation target area was the anatomical region between TH3 and TH10 depending on the localization of the resected lobe. The mean doses of the ionizing energy was 8.5 Gy ± 3.5 Gy. Results The median start date of the radiation was the fourth day after chylothorax diagnosis. The patients’ mediastinum was radiated an average of six times. Radiotherapy, in combination with dietary restrictions, was successful in all patients. The median time between the end of the radiation and the removal of the chest tube was one day. One patient underwent wound healing by secondary intention. The median time between the end of radiation and discharge was three days, and the overall hospital stay between the chylothorax diagnosis and discharge was 18 days (range: 11–30 days). After a follow-up of six months, no patient experienced chylothorax recurrence. Conclusions Our results suggest that radiotherapy in combination with dietary restriction in the treatment of postoperative chylothorax is very safe, rapid and successful. This novel interventional procedure can obviate repeat major thoracic surgery and shorten hospital stays and could be the first choice in the treatment of postthoracotomy chylothorax. PMID:23566741

    2005-01-01

    Summary Opioids alone sometimes provide insufficient postoperative analgesia. Co-administration of drugs may reduce opioid use and to improve opioid efficacy. We therefore tested the hypothesis that administration of ketamine or nefopam, to postoperative patients with pain only partly alleviated by morphine, limits the amount of subsequent opioid necessary to produce adequate analgesia. Patients (n=77) recovering from major surgery were given up to 9 mg intravenous morphine. Those still suffering from pain were randomly assigned to blinded administration of: 1) isotonic saline (Control, n=21); 2) ketamine 10 mg (Ketamine, n=22); or, 3) nefopam 20 mg (Nefopam, n=22). Three-mg morphine boluses were subsequently given at 5-minute intervals until adequate analgesia was obtained, or 60 minutes elapsed after the beginning of the study drug administration, or ventilation became insufficient (respiratory rate < 10 breath/minute or saturation by pulse oxymetery < 95%). Supplemental morphine (i.e., after test drug administration) requirements were significantly greater in the Control group [17 ± 10 (SD) mg] than in the Nefopam (10 ± 5 mg, P < 0.005) or Ketamine (9 ± 5 mg, P < 0.001) groups. Morphine titration was successful in all Ketamine and Nefopam patients, but failed in four Control patients (two from respiratory toxicity and two from persistent pain). Tachycardia and profuse sweating were more frequent in patients given nefopam and sedation was greater with ketamine; however, the incidence of other potential complications did not differ between groups. Implications We conclude that ketamine 10 mg and nefopam 20 mg comparably potentiate opioid analgesia, each reducing opioid need by approximately 40%. Ketamine administration was associated with sedation whereas nefopam produced tachycardia and sweating. However, none of the side effects was serious. Either drug can thus be used to potentiate opioid analgesia. PMID:15616073

    A 54-year-old woman with an epiretinal membrane in her left eye accompanied by a shallow anterior chamber due to primary angle closure glaucoma underwent vitrectomy and cataract surgery. During the cataract surgery, immediately after the ultrasonic tip had been removed from the anterior chamber, anterior chamber flattening occurred. An intraoperative fundus examination showed the development of acute intraoperative choroidal effusion. Postoperatively, the anterior chamber remained shallow even after the choroidal detachment had subsided; capsular bag distension seen by ultrasound biomicroscopy suggested the development of early postoperative capsular block syndrome. After neodymium:yttrium-aluminium-garnet laser capsulotomy, the anterior chamber deepened. Depending on the perioperative period, the mechanism of a flat anterior chamber can change, and understanding the underlying mechanisms is required for appropriate treatment. PMID:27293412

    Postoperative toxic shock syndrome (PTSS) after orthopedic surgery is rare, but early recognition and prompt intervention are essential to minimize morbidity and potential mortality. The diagnosis should be considered in all postoperative patients presenting with fever, hypotension, and systemic illness. The treating surgeon must have not only knowledge of the clinical entity, but also an extremely high index of suspicion, because the diagnosis can be elusive with surgical wounds appearing deceptively benign. Treatment consists of antibiotics, surgical wound debridement, and, more importantly, aggressive supportive care with intravenous fluids and intensive care surveillance. To date, the literature contains relatively few case reports of PTSS after orthopedic procedures, with even fewer cases encountered after foot and ankle surgery. This report describes a patient who developed the rare complication of PTSS after an elective ganglion cyst excision from the ankle. PMID:16818157

    Irradiation can complicate surgical wound healing, yet little is known of the importance of the time between surgery and irradiation on this process. This study investigated the impact of post-operative irradiation on gain in wound tensile strength in a murine skin model. Irradiation on the same day as wounding or to 2-day-old wounds reduced wound tensile strength. In contrast, postoperative irradiation delivered at 7, 9 and 14 days transiently enhanced wound tensile strength, as measure d 3 but not 4 or 5 weeks later. This effect was independent of the inclusion (hemi-body) or exclusion (skin alone) of the hematopoietic system in the field of irradiation. Radiation-enhanced wound tensile strength was greater and occurred earlier after higher radiation doses. Even though the effect of irradiation in enhancing wound tensile strength is transitory, it could be important in assisting early wound healing. 14 refs., 3 figs., 1 tab.

More than 70,000 serum samples were obtained from subjects of either sex 1-99 years of age in each of the 32 states of the country. The current collection of sera includes 28,704 male samples and 40,629 female samples. This paper describes the procedures for handling serum samples, including reception registry, storage and distribution to several laboratories for detection of measles, rubella, poliomyelitis, AIDS, diphtheria, pertussis, tetanus, brucella, salmonella, amoeba, toxoplasma, American trypanosomiasis and cysticercus. Determinations of total cholesterol were also made in order to describe its distribution and to identify the prevalence of hypercholesterolemia.

    Background/Objectives Tryptophan deficiency has been associated with increased incidence of postoperative delirium. Therefore, we hypothesized that the post-operative administration of tryptophan would be beneficial for elderly surgical patients who are at higher risk of developing post-operative delirium. Design Randomized, double-blind, placebo controlled trial. Setting: Participants A total of 325 individuals aged 60 years and older undergoing major elective operations requiring a postoperative intensive care unit admission. Intervention L-tryptophan, 1 gram orally, three times daily or placebo was started following the operation and continued for up to three days postoperatively. Measurements Delirium and its motor subtypes were measured using the Confusion Assessment Method-ICU and the Richmond Agitation and Sedation Scale. The primary outcome for between groups comparison was the incidence of excitatory (mixed and hyperactive) postoperative delirium. The secondary outcomes for comparison were the incidence and duration of overall postoperative delirium. Results The overall incidence of postoperative delirium was 39% (116) (95% confidence interval 34% to 44%). The percentages of patients with excitatory delirium in the tryptophan and placebo groups were 17% and 9% (p=0.176), and the duration of excitatory delirium was 3.3±1.7 and 3.1±1.9 days (p=0.741). The percentage of patients with overall delirium in the tryptophan and placebo groups was 40% and 37% (p=0.597), and the duration of overall delirium was 2.9±1.8 and 2.4±1.6 days (p=0.167). Conclusion Postoperative tryptophan supplementation in older adults undergoing major elective operations requiring postoperative intensive care unit admission demonstrated no efficacy in reducing the incidence of postoperative excitatory delirium or overall delirium, and the duration of excitatory or overall delirium.

    Autonomic behavior is subject to direct suggestion. We found that patients undergoing major operations benefit more from instruction than from information and reassurance. We compared the return of intestinal function after intra-abdominal operations in 2 groups of patients: the suggestion group received specific instructions for the early return of gastrointestinal motility, and the control group received an equal-length interview offering reassurance and nonspecific instructions. The suggestion group had a significantly shorter average time to the return of intestinal motility, 2.6 versus 4.1 days. Time to discharge was 6.5 versus 8.1 days. Covariates including duration of operation, amount of intraoperative bowel manipulation, and amount of postoperative narcotics were also examined using the statistical model analysis of covariance. An average savings of $1,200 per patient resulted from this simple 5-minute intervention. In summary, the use of specific physiologically active suggestions given preoperatively in a beleivable manner can reduce the morbidity associated with an intra-abdominal operation by reducing the duration of ileus.

    1996-07-01

    To evaluate continuous pulse amplitude monitoring (CPAM) as a method for early postoperative graft surveillance following infrainguinal bypass surgery, a prospective observational study was carried out in 34 consecutive infrainguinal bypass grafts. CPAM tracings were compared with pre- and postoperative pulse palpation, ankle/brachial index (ABI) measurements, and pulse volume recordings (PVR). The utility of each method was defined by its ability to demonstrate graft patency in the first 24 hours. Pulse palpation was considered a useful monitoring tool if a postoperative pedal pulse was found in the absence of palpable preoperative pulses. The ABI qualified in this respect if a postoperative increase of at least 0.25 could be demonstrated; for PVR tracings an increase of at least one category was required. The utility of CPAM was established by an increase of at least 5 mm compared to the preoperative values. There were no early graft failures. We were therefore unable to calculate the ability of the studies to predict graft failure. The percentages (95% confidence limits) for which pulse palpation, ABI, and PVR were found capable of demonstrating graft patency were 50% (range 34% to 66%), 53% (range 36% to 70%), and 71% (range 54% to 83%), respectively. CPAM appeared to be far superior to these three methods with a utility of 94% (range 81% to 98%; p < 0.05). Patient and operator acceptability of CPAM was high. Skin pressure problems are a potential risk if the CPAM probe is left attached to the skin for more than 24 hours. CPAM was a valuable and reliable means of monitoring infrainguinal vascular reconstructions. Apart from being inexpensive, continuous, objective, and simple, CPAM is noninvasive and painless. It is advisable to remove the probe 24 hours after surgery, when the most crucial period for graft monitoring has passed. PMID:8879395

    The aim of this study was to evaluate serum calprotectin levels and oxidative stress status in patients with papillary thyroid carcinoma (PTC) and the changes in their levels after total thyroidectomy. The study involved 30 patients with PTC and 30 healthy controls. Blood samples were obtained from the PTC patients before and 1 month after the operation. Preoperative and postoperative serum samples from PTC patients and healthy controls were analysed for calprotectin, total antioxidant status (TAS), total oxidant status (TOS) and lipid hydroperokside (LOOH). The preoperative calprotectin, TOS, OSI and LOOH levels of the patients with PTC were significantly higher compared to those of the control group (p < 0.001, for each). The levels of calprotectin decreased significantly in patients with PTC after the operation (p < 0.001), while TAS, TOS and OSI levels remained unchanged (p = 0.313, p = 0.085 and p = 0.163, respectively). Preoperative serum calprotectin levels were positively correlated with TOS, OSI and LOOH levels and negatively correlated with TAS levels in patients with PTC. In conclusion, serum calprotectin levels is increased in patients with PTC, and calprotectin is positively correlated with TOS and LOOH. Serum calprotectin levels is significantly decreased after total thyroidectomy.

    The efficiency and safety of postoperative use of propacetamol was estimated in 30 patients by means of double blind placebo controlled method. The first group consisted of 15 patients to whom propacetamol was introduced intravenously in single dose of 2 g along with patient controlled anesthesia with promedol. Placebo in combination with patient control anesthesia were used in 15 patients from the 2nd group. Intravenous introducing of propacetamol in dose of 2 g in 15 minutes provides relief of pain intensity in postoperative period. So it permits to consider propacetamol as basic non-opioid analgesic. In early postoperative period combination of propacetamol and opioid analgesic (promedol) reduces demands in the latter by 44%. PMID:12462772

    The aim of this study was to determine whether objective ocular torsion in intermittent exotropia (IXT) changes after recession surgery, and to evaluate the relationship between change in ocular torsion and clinical parameters in IXT. Sixty patients between 3 and 14 years of age underwent lateral rectus (LR) recession for IXT. Digital fundus photographs were obtained from both eyes of each subject and the disc-foveal angle (ocular torsion) was calculated using image software. We compared the preoperative and postoperative amount of ocular torsion, and analyzed the correlation between the difference in ocular torsion (DOC) and clinical parameters including age, duration of strabismus, stereoacuity, amount of preoperative exodeviation, and mean dose response. We categorized the patients according to DOC value: positive DOC value as group 1, and negative DOC value as group 2. A correlation between ocular torsion dominance and fixation preference was also investigated using the Kappa test. The mean ocular torsion was 15.8 ± 4.6 degrees preoperatively and 13.7 ± 5.1 degrees postoperatively. Compared with preoperative values, the mean ocular torsion showed a significant decrease after LR recession (p<0.001), and a greater preoperative ocular torsion was significantly associated with the amount of DOC (r = 0.37, p<0.001). Degree of stereopsis, mean dose-response, and postoperative exodeviation were significantly different between group 1 (positive DOC) and group 2 (negative DOC) (p<0.001, 0.030, and 0.001 respectively). The Kappa test showed that there was a significant correlation between the dominance of ocular torsion and fixation preference (p = 0.020). Therefore, change in ocular torsion after LR recession can be a useful supplementary indicator for evaluating the degree of fusional control and for predicting postoperative surgical response in IXT.

    INTRODUCTION Postoperative nausea and vomiting (PONV), and postoperative pain are common during the early postoperative period. In addition to these problems, elderly patients risk developing postoperative confusion. This study aimed to identify the risk factors associated with these problems, and the extent of these problems, in a Singapore inpatient surgical population. METHODS Over a period of six weeks, we surveyed 707 elective surgical inpatients aged ≥ 18 years who received general anaesthesia and/or regional anaesthesia. RESULTS The incidence of PONV was 31.8%(95% confidence interval [CI] 34.8–41.9). The incidence increased with increasing Apfel score (p < 0.001) and were higher in female patients (odds ratio [OR] 1.74, 95% CI 1.28–2.36), non-smokers (OR 1.72, 95% CI 1.04–2.88), patients with a history of PONV and/or motion sickness (OR 3.45, 95% CI 2.38–5.24), patients who received opioids (OR 1.39, 95% CI 1.03–1.88), and patients who received general anaesthesia (OR 1.76, 95% CI 1.11–2.79). Moderate to severe pain at rest and with movement were reported in 19.9% and 52.5% of patients, respectively. Among the patients who were predicted to experience mild pain, 29.5% reported moderate pain and 8.1% reported severe pain. The prevalence of postoperative confusion was 3.9% in the geriatric population. CONCLUSION Higher Apfel scores were associated with a higher risk of PONV and multimodal treatment for postoperative pain management was found to be insufficient. The incidence of postoperative confusion was low in this study. PMID:25640098

    Postoperative spondylodiscitis is relatively uncommon. This complication is associated with increased cost, and long-term of inability to work, and even morbidity. Although the majority of postoperative spondylodiscitis cases can be well managed by conservative treatment, postoperative spondylodiscitis after internal fixation and those cases that are unresponsive to the conservative treatment present challenges to the surgeon. Here, a review was done to analyze the treatment of postoperative spondylodiscitis with/without internal fixation. This review article suggested that majority of postoperative spondylodiscitis without internal fixation could be cured by conservative treatment. Either posterior or anterior debridement can be used to treat postoperative spondylodiscitis without internal fixation when conservative treatment fails. In addition, minimally invasive debridement and drainage may also be an alternative treatment. In case of postoperative spondylodiscitis after internal fixation, surgical treatment was required. In the cervical spine, it can be well managed by anterior debridement, removal of internal fixation, and reconstruction of the spinal stability by using bone grafting/cage/anterior plate. Postoperative spondylodiscitis after internal fixation is successfully managed by combined anterior debridement, fusion with posterior approach and removal of pedicle screw or extension of pedicle screw beyond the lesion site, in the thoracic and lumbar spine.

    Cerebrospinal fluid (CSF) leakage is a serious postoperative complication associated with total en bloc spondylectomy. The authors examined the risk factors for CSF leakage after this procedure. A total of 72 patients underwent total en bloc spondylectomy at the authors' institution between May 2010 and April 2013. Postoperative CSF leakage was observed in 17 of the 72 patients (23.6%). The results of univariate analysis suggested that age 54 years or older, preoperative surgical site irradiation, resection of 3 or more vertebral bodies, and dural injury were significant risk factors for postoperative CSF leakage after total en bloc spondylectomy. Multivariate analysis showed that preoperative surgical site irradiation was the only significant risk factor for postoperative CSF leakage (adjusted odds ratio, 5.22; 95% confidence interval, 1.03-26.45, P=.046). The authors also assessed the course of treatment for postoperative CSF leakage in each patient. Of 17 patients with postoperative CSF leakage, 13 recovered without further complications, but 4 required reoperation (2 for wound dehiscence, 1 for surgical site infection, and 1 for severe intracranial hypotension). All 4 patients who required reoperation had a history of surgical site irradiation. Thus, this study suggests that careful consideration should be given to postoperative CSF leakage in patients with a history of surgical site irradiation. These findings may contribute to the management of postoperative CSF leakage associated with total en bloc spondylectomy and supplement the information given to the patient in the process of obtaining informed consent.

    Previously published reports have shown good results after proximal row carpectomy in all cases that had a postoperative immobilisation period from 1 to 4 weeks. Immobilisation is thought to be necessary because of the risk of postoperative subluxation of the carpus and for pain relief. There is, however, no evidence of its value. The results in 13 patients who underwent proximal row carpectomy without postoperative immobilisation were compared with those in 25 patients who underwent proximal row carpectomy with postoperative immobilisation for 4 weeks. After a mean follow-up period of 27 months, no significant differences were found for pain, range of motion or return to work between the two groups. We conclude that postoperative immobilisation is not necessary after proximal row carpectomy.

  19. Influence of various irrigation fluids on serum enzyme patterns following transurethral resection of the prostate.

    Serum levels of a variety of enzymes were determined preoperatively and repeatedly postoperatively in a comprehensive biochemical study of 60 patients undergoing transurethral resection of the prostate (TURP). These patients were divided into four groups depending on the type of fluid used for irrigation during TURP. Prostatic acid phosphatase (PAP, analysed by radio-immunoassay) in serum showed a marked postoperative increase but wide inter-individual variation in all groups. It returned to normal within 24 to 48 hours. When water was used for irrigation, similar but less pronounced increases were observed for serum lactate dehydrogenase (LD, LD-1) and aminotransferases (ASAT, ALAT). This is interpreted as being due to an influx of irrigating fluid into the general circulation from the bladder through opened veins, by absorption from a perivesical accumulation or, in the case of PAP, also from the prostatic wound. The enzyme increases (other than PAP) may be due to their release from haemolysed red cells in the bladder or in a perivesical fluid accumulation, which conjecture is supported by the marked increase also seen in plasma haemoglobin. When iso-osmolar fluids were used for irrigation signs of haemodilution, such as a postoperative decrease in serum sodium, were observed. Several of the variables studied may be used as markers to indicate the quantity of irrigating fluid absorbed during resection. Plasma haemoglobin, serum LD (or LD-1) in connection with water irrigation, serum sodium in connection with iso-osmolar fluid irrigation and serum PAP, regardless of the type of irrigating fluid used, are some practical suggestions for such markers.

    The purpose of this ongoing study is to determine whether thoracic radiotherapy for lung cancer produces an early increase in serum copper (Cu) concentration, an increase which might predict clinical outcome. Copper and iron concentrations were measured in serum obtained from nonsmall cell lung cancer patients at 0, 1, 2, 4, and 6 weeks after the start of radiotherapy. Control groups included patients irradiated for breast cancer (low dose of radiation to the lung), for endometrial, cervical or prostatic cancer, and patients with congestive heart failure, pulmonary hypertension, chronic obstructive pulmonary disease (COPD), and cutaneous burns with or without smoke inhalation. Serum Cu concentration increased at least 10 micrograms/dl from the pretreatment level in approximately 75% of the adenocarcinoma and squamous cell lung cancer patients, but in only 1 of 4 undifferentiated lung cancer cases. In virtually all of these responders, serum Cu increased to a maximum at 2 weeks after the start of therapy, then plateaued or decreased slightly despite continuing irradiation. Within the subset of squamous cell lung cancers, there was a direct correlation between the degree of histologic differentiation and both baseline serum Cu concentration and the probability of an early increase therein. In contrast, only 33% of breast cancer patients and 15% of endometrial, cervical and prostate cancer patients exhibited an increase in serum Cu concentration at 2 weeks after the start of radiotherapy. Serum Cu concentration was within normal limits in virtually all patients with congestive heart failure, pulmonary hypertension, and COPD. Burn patients exhibited a significant reduction in serum Cu, although concomitant smoke inhalation increased serum Cu back to low-normal levels. Serum iron concentration did not change significantly in any category of patients.

    Background To assess the feasibility and safety of tubeless video-assisted thoracoscopic surgery (VATS) under non-intubated, intravenous anesthesia with spontaneous ventilation and no placement of a chest tube postoperatively compared with VATS under intubated anesthesia with single-lung mechanical ventilation. Methods A total of 91 patients undergoing tubeless VATS (60 sympathectomies, 22 bullae resections, and 9 mediastinal tumor resections) between December 2012 and December 2015 were included. Additionally, 82 patients were treated by VATS by the same team while under intubated general anesthesia (52 sympathectomies, 19 bullae resections, and 11 mediastinal tumor resections). Comprehensive early outcome data, including intraoperative and postoperative variables, were compared between the subgroups. Results In total, 89 patients in the tubeless group underwent an effective operation and exhibited good postoperative recovery, while 2 (one sympathectomy and one bullae resection) had their operation aborted for some reason. The tubeless group showed advantages in the postoperative fasting time, the mean duration of the postoperative hospital stay, and postoperative pain scores, while no significant difference was found in intraoperative blood loss, the operation time or postoperative complications between the tubeless group and the intubated group. Furthermore, 83% (49/59) of sympathectomies, 81% (17/21) of bullae resections, and 56% (5/9) of mediastinal tumor resections were achieved via day surgery. Conclusions In this study, our experience has shown that tubeless VATS is a safe and feasible surgery with certain advantages in selected patients with thoracic disease and that we can achieve day surgery in these cases.
