Single-incision laparoscopy (SIL) has been developed to reduce surgical trauma, whereas technical difficulties in bleeding control limit the broad acceptance for hepatectomy. A novel minimized invasive strategy combining inline radiofrequency pre-coagulation and transumbilical SIL is presented herein.A cohort of 21 selected patients underwent transumbilical SIL hepatectomies (segmentectomies II-VI) utilizing inline radiofrequency pre-coagulation for hepatic transection (Habib 4X). Bleeding control, postoperative complications and positive resection margins in malignant diseases served as primary and secondary outcome parameters, respectively.Single-incision laparoscopy was successfully completed in all patients. A total of 33 segments were retrieved: mean resection time was 6635min, including 11 anatomical (52.38%) and 10 non-anatomical (47.62%) resections. Sixteen patients (76.19%) underwent concomitant abdominal surgery. No substantial blood loss occurred. Neither additional staplers nor clips were necessary to control any bleeding or bile leakage. One pleural effusion counted for the only postoperative complication. Free margins could be achieved in all but one resection (12/13 patients with malignancies; 92.31%). Ninety-day mortality was zero.The combination of SIL and inline radiofrequency pre-coagulation proved to be a simple, efficacious and safe technique in minor hepatectomy.

Objectives: Tobacco dependence and depression are believed to have a common familial component, most probably genetic, and mood disorders have been reliably associated with failure to stop smoking. Variant genotypes of the Taq1A (DRD2/ANKK1, 32806T, rs1800497) polymorphism have been associated with failure to stop smoking in some studies, but not others. We investigated the association between Taq1A genotypes and smoking cessation, while also considering mental health. Materials and Methods: This was a prospective study in 419 smokers who attended a smoking cessation clinic and used standard doses of nicotine replacement therapy. DNA samples and baseline measures including demographics, severity of tobacco dependence, mental health history and history of drug misuse were taken. Smoking cessation at the end of treatment was biochemically verified using expired-air carbon monoxide. Results: We found no simple relation between Taq1A genotype and smoking cessation, although the association between cessation and lifetime depression was significantly modified by genotype. The relationship was such that for those having only common alleles there was no association between depression and stopping smoking, whereas for those with at least one variant allele (A1A2/A1A1) depression was associated with a two-fold reduction in the likelihood of stopping. Conclusion: Those having a Taq1A variant allele and a history of depression are likely to experience particular difficulty when trying to stop smoking and may require treatment other than standard doses of nicotine replacement. This finding might explain previous conflicting results for Taq1A and smoking cessation in studies where depression history was not measured, and may help to explain the underlying link between depression and smoking. © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Objective: The authors developed and validated a clozapine-specific side-effects scale capable of eliciting the subjectively unpleasant side-effects of clozapine. Methods: Questions from the original Glasgow Antipsychotic Side-effects Scale (GASS) were compared to a list of the most commonly reported clozapine side-effects and those with a significant subjective burden were included in the GASS for Clozapine (GASS-C). The original authors of the GASS and a group of mental health professionals from the UK and Ireland were enlisted to comment on the questions in the GASS-C based on their clinical experience. 110 clozapine outpatients from two sites completed the GASS-C, the original GASS and a repeat GASS-C. Statistical analyses were performed using SPSS for Windows version 19. Results: The GASS-C was shown to have construct validity, in that Spearman's correlation coefficient was 0.816 (p. <. 0.001) with the original GASS, whilst Cohen's kappa coefficient was >. 0.77 (p. <. 0.001) for one question and >. 0.81 (p. <. 0.001) for remaining relevant questions. GASS-C was also shown to have strong test-retest reliability, in that Cronbach's alpha coefficient was >. 0.907 (p. <. 0.001), whilst Cohen's kappa coefficient was >. 0.81 (p. <. 0.001) for 12 questions and >. 0.61 (p. <. 0.001) for the remaining four questions. Conclusion: The GASS-C is a valid and reliable clinical tool to enable a systematic assessment of the subjectively unpleasant side-effects of clozapine. Future research should focus on how the scale can be utilised as a clinical tool to improve real-world outcomes such as adherence to clozapine therapy and quality of life. © 2015 Elsevier B.V.

Background Positive surgical margins (PSMs) are a known risk factor for biochemical recurrence in patients with prostate cancer (PCa) and are potentially affected by surgical technique and volume. Objective To investigate whether radical prostatectomy (RP) modality and volume affect PSM rates. Design, setting, and participants Fourteen institutions in Europe, the United States, and Australia were invited to participate in this study, all of which retrospectively provided margins data on 9778 open RP, 4918 laparoscopic RP, and 7697 robotic RP patients operated on between January 2000 and October 2011. Outcome measurements and statistical analyses The outcome measure was PSM rate. Multivariable logistic regression analyses and propensity score methods identified odds ratios for risk of a PSM for one modality compared with another, after adjustment for age, preoperative prostate-specific antigen, postoperative Gleason score, pathologic stage, and year of surgery. Classic adjustment using standard covariates was also implemented to compare PSM rates based on center volume for each minimally invasive surgical cohort. Results and limitations Open RP patients had higher-risk PCa at time of surgery on average and were operated on earlier in the study time period on average, compared with minimally invasive cohorts. Crude margin rates were lowest for robotic RP (13.8%), intermediate for laparoscopic RP (16.3%), and highest for open RP (22.8%); significant differences persisted, although were ameliorated, after statistical adjustments. Lower-volume centers had increased risks of PSM compared with the highest-volume center for both laparoscopic RP and robotic RP. The study is limited by its nonrandomized nature; missing data across covariates, especially year of surgery in many of the open cohort cases; lack of standardized histologic processing and central pathology review; and lack of information regarding potential confounders such as patient comorbidity, nerve-sparing status, lymph node status, tumor volume, and individual surgeon caseload. Conclusions This multinational, multi-institutional study of 22 393 patients after RP suggests that PSM rates might be lower after minimally invasive techniques than after open RP and that PSM rates are affected by center volume in laparoscopic and robotic cases. Patient summary In this study, we compared the effectiveness of different types of surgery for prostate cancer by looking at the rates of cancer cells left at the margins of what was removed in the operations. We compared open, keyhole, and robotic surgery from many centers across the globe and found that robotic and keyhole operations appeared to have lower margin rates than open surgeries. How many cases a center and surgeon do seems to affect this rate for both robotic and keyhole procedures. © 2013 European Association of Urology.

Clinical practice guidelines (CPGs) support the translation of research evidence into clinical practice. Key health questions in CPGs ensure that recommendations will be applicable to the clinical context in which the guideline is used. The objectives of this study were to identify CPGs for the pharmacological treatment of first-episode schizophrenia; assess the quality of these guidelines using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument; and compare recommendations in relation to the key health questions that are relevant to the pharmacological treatment of first-episode schizophrenia.A multidisciplinary group identified key health questions that are relevant to the pharmacological treatment of first-episode schizophrenia. The MEDLINE and EMBASE databases, websites of professional organisations and international guideline repositories, were searched for CPGs that met the inclusion criteria. The AGREE II instrument was applied by three raters and data were extracted from the guidelines in relation to the key health questions.In total, 3299 records were screened. 10 guidelines met the inclusion criteria. 3 guidelines scored well across all domains. Recommendations varied in specificity. Side effect concerns, rather than comparative efficacy benefits, were a key consideration in antipsychotic choice. Antipsychotic medication is recommended for maintenance of remission following a first episode of schizophrenia but there is a paucity of evidence to guide duration of treatment. Clozapine is universally regarded as the medication of choice for treatment resistance. There is less evidence to guide care for those who do not respond to clozapine.An individuals experience of using antipsychotic medication for the initial treatment of first-episode schizophrenia may have implications for future engagement, adherence and outcome. While guidelines of good quality exist to assist in medicines optimisation, the evidence base required to answer key health questions relevant to the pharmacological treatment of first-episode schizophrenia is limited.

Gastrointestinal stromal tumours (GISTs) are a rare class of neoplasms that are seen most commonly in the stomach. Due to their malignant potential, surgical resection is the recommended method for management of these tumours. Many reports have described the ability to excise small and medium sized GISTs laparoscopically, but laparoscopic resection of GISTs greater than 5 cm is still a matter of debate.To investigate the feasibility and effectiveness of laparoscopic surgical techniques for management of large gastric GISTs greater than 4 cm and to detail characteristics of this type of tumour.The study cohort consisted of 11 patients with suspected gastric GISTs who were treated from 2011 to April 2014 in a single institution. All patients underwent laparoscopic resection of a gastric GIST.Eleven patients underwent laparoscopic resection of a suspected gastric GIST between April 2011 and April 2014. The cohort consisted of 6 males and 5 females. Mean age was 67 years (range: 43-92 years). Sixty-four percent of these patients presented with symptomatic tumours. Four (36.4%) patients underwent laparoscopic transgastric resection (LTR), 3 (27.3%) laparoscopic sleeve gastrectomy (LSG), 3 (27.3%) laparoscopic wedge resection (LWR) and 1 (9%) laparoscopic distal gastrectomy (LDG). The mean operative time was 215 min. The mean tumour size was 6 cm (range: 4-9 cm). The mean tumour size for LTR was 5.5 cm (range: 4-6.3 cm), for LWR 5.3 cm (range: 4.5-7 cm), for LSG 6.5 cm (range: 4-9 cm) and for LDG 9 cm. We experienced only minor postoperative complications.Laparoscopic procedures can be successfully performed during management of large gastric GISTs, bigger than 4 cm, and should be considered for all non-metastatic cases. The appropriate approach can be determined by assessing the anatomical location of each tumour.

Introduction and hypothesis Pelvic organ prolapse (POP) is a common condition. The use of pessaries for conservative management of POP is widespread. However, there are little data on the use of cube pessaries. The aim of our study was to evaluate whether self-therapy with the use of vaginal cube pessaries in women with POP can be a well-tolerated, firstline treatment. Methods In a prospective case series, 87 women who suffered from symptomatic POP, stages II-IV, were instructed in self-treatment with a vaginal cube pessary. Differences were analyzed using Wilcoxon's rank sum test or Fisher's exact test. Results A pessary could be fitted in 84/87 patients (96.6%); 6 women were lost to follow-up. The remaining 78 patients (92.9 %, median age 60 years) completed the study. Sixteen women (20.5 %) chose not to continue with the pessary treatment. For these patients, general well-being decreased from a median numeric rating score (NRS) of 4.5 (3-6) to 2.0 (1-3, p<0.001). In those who continued treatment, general well-being increased from a median NRS of 3.0 (2-5) to 8.0 (7-10, p<0.001) after 1 year of use. The majority of patients (53) in the present study rated pessary self-care use as "very easy" or "easy" (85.5 %). The Patient Global Impression of Improvement (PGI-I) was 2.0 (1-3) at follow-up examination. There were no complications or adverse effects of pessary use. Conclusions Conservative self-treatment with vaginal cube pessaries might be a feasible treatment option for women who suffer from POP. © The International Urogynecological Association 2013.

Expert Opinion on Investigational Drugs | Year: 2015
Introduction: Ulcerative colitis (UC) is a life-long, immunologically mediated condition that results from an inappropriate activation of the mucosal immune system by intestinal luminal antigens in genetically susceptible individuals. TNF-α is a pro-inflammatory cytokine central to UC pathogenesis. Areas covered: This review examines the evidence for the use of the anti-TNF (αTNF) medications infliximab, adalimumab, certolizumab and golimumab in the management of UC. It highlights the newer biosimilar agents that are becoming available and the early stage investigation of an orally administered αTNF agent. Expert opinion: αTNF therapy is effective but only in a proportion of UC patients. As there is now strong evidence that UC is not just a single disease but a series of phenotypes with distinct genetic, serological and environmental aspects, understanding the heterogeneity of the innate immunological response in UC could allow for better targeted patient management. Identifying differences in the efficacy of the various αTNF agents is difficult as there are no head-to-head studies, but only infliximab has proven clinical efficacy in the management of acute severe colitis. Biosimilars to the αTNF agents are now available and with the added competition, medications costs should fall allowing for greater patient access. © 2015 Informa UK, Ltd.

The aim of this study was to investigate differences in pain, range of movement function and satisfaction at three months and one year after total knee arthroplasty (TKA) in patients with an oblique pattern of kinematic graph of the knee and those with a varus pattern.A total of 91 patients who underwent TKA were included in this retrospective study. Patients (59 women and 32 men with mean age of 68.7 years; 38.6 to 88.4) were grouped according to kinematic graphs which were generated during navigated TKA and the outcomes between the groups were compared.The graphs were varus in 50 patients (55%), oblique in 19 (21%), neutral in 17 (18.5%) and valgus in five (5.5%). After adjustment for pre-operative scores and gender, compared with patients with varus knee kinematics, patients with an oblique kinematic graph had a poorer outcome with lower Knee Society scores at three months (9.2 points, p = 0.038).We found four distinct kinematic graphs in knees and that patients with an oblique graph have a poorer outcome in the short-term after TKA.

Use of the Freedom SOLO (FS) stentless aortic bioprosthesis is limited by a unique and as yet unexplained severe decrease in postoperative platelet count in the absence of FS-related excess bleeding or thromboembolism. We investigated whether anticoagulant-associated pseudothrombocytopaenia could explain this complication.Thirty consecutive patients (mean age 75.47.7 years, 11 [36.7%] female) underwent elective aortic valve replacement (AVR) with either the stented bovine Mitroflow (MF, n=18) or the stentless bovine FS (n=12) aortic valve bioprostheses. Serial platelet counts were performed simultaneously with sampling tubes containing tripotassium (KPostoperative platelet counts decreased compared with preoperative values in all patients (p<0.001), but were significantly lower in patients receiving FS compared to MF at all measurement time points until the end of observation (day 9). Lowest platelet counts were seen on the first postoperative day for MF (mean reduction: -41.5%) and on the second postoperative day for FS (mean reduction: -59.9%). Postoperative platelet counts did not correlate with any of the anticoagulants, thereby indicating no pseudothrombocytopaenia in the study population. There was no interaction between anticoagulant and type of valve. Only 1% of variance in platelet counts was caused by the anticoagulant, 46% by the day of measurement relative to baseline, and 20% was caused by the type of valve.The platelet-lowering effect in patients receiving the FS is valve-dependent and is not caused by systemic preanalytical (laboratory) measurement error such as anticoagulant-dependent pseudothrombocytaemia, particularly with EDTA and citrate.
