Incidental adrenal masses - A primary care approach.

BACKGROUND: The common use of cross-sectional imaging for the investigation of abdominal and thoracic illness has resulted in the rise of the incidentally identified adrenal mass, or incidentaloma, which presents a diagnostic and management dilemma for the primary care physician. OBJECTIVE: This article provides a framework for the investigation and management of incidental adrenal masses. DISCUSSION: Adrenal incidentalomas are found in approximately 3-4% of abdominal computed tomography (CT) scans. It is important to evaluate these incidental adrenal lesions to determine what treatment, if any, is needed and when specialist referral may be necessary. In particular, incidentalomas must be evaluated in regard to their functional status and malignant potential, as lesions can range from being indolent, benign and non-functioning tumours that can simply be observed, to aggressive and hormonally active malignant lesions that require urgent surgical intervention.

Repeat transurethral resection for non-muscle-invasive bladder cancer: a contemporary series.

OBJECTIVES: To evaluate the depth of transurethral resections of bladder tumour (TURBT), residual cancer rates and up-staging rates in a contemporary Australian series. MATERIALS AND METHODS: Specimen reports from a single, major reporting pathology centre, servicing a group of urological oncologists in Sydney were obtained for TURBTs performed between October 2008 and February 2013. We examined the depth of TURBT, rates of repeat-TURBT (re-TUR) and residual cancer rates at the 3-6 month check cystoscopy. RESULTS: One thousand and two hundred and nine transurethral resection specimens retrieved during this period were analysed. There were 162 (13.4%) T1 specimens and 631 (52.2%) Ta specimens, 218 (34.5%) of which were high grade. Muscularis propria was present in 506 (41.9%) specimens in total and in 151 (39.7%) of 380 high-risk specimens (high grade Ta, T1). Of the 380 high-risk non-muscle-invasive tumours, 85 (22.4%) proceeded to re-TUR. Of the 48 T1 specimens and 37 Ta high grade specimens that proceeded to re-TUR, 7 (14.6%) and 1 (2.7%) respectively were upstaged to muscle-invasive disease. Rates of residual disease/early recurrence at 3-6 months was significantly better for those with re-TUR compared to those without 56.8% vs 82.5% (P < 0.001) for Ta high grade and 39.6% vs 84% (P = 0.028) for T1 tumours respectively. CONCLUSION: Re-TUR rates in high-risk non-muscle-invasive bladder cancer are low. However in a contemporary series, the upstaging rates are low, but residual cancer rates high, supporting the need for re-TUR in this population.

Vaginal hysterectomy versus total laparoscopic hysterectomy for benign disease: a metaanalysis of randomized controlled trials.

OBJECTIVE: Recent randomized trials comparing total laparoscopic hysterectomy (TLH) and vaginal hysterectomy (VH) have produced conflicting results. The role of TLH in women suitable for VH remains uncertain. STUDY DESIGN: This study was a metaanalysis of randomized studies comparing TLH and VH for benign disease. Pooled outcome measures (odds ratio [OR] and weighted mean difference [WMD]) were calculated using random-effects models. RESULTS: No differences in perioperative complications, either total (pooled odds ratio, 0.87; P = .74) or by grade of severity, were demonstrated. TLH was associated with reduced postoperative pain scores (WMD -2.1; P = .03) and reduced hospital stay (WMD -0.62 days; P < .0001) but took longer to perform (WMD 29.3 minutes; P = .003). No differences in blood loss, rate of conversion to laparotomy, or urinary tract injury were identified. CONCLUSION: TLH may offer benefits compared with VH for benign disease, although this analysis is likely underpowered for rare complications. Further studies of long-term outcomes, including prolapse, urinary incontinence, and sexual function, are required.

A Systematic Review and Meta-Analysis of Pelvic Drain Insertion After Robot-Assisted Radical Prostatectomy.

Purpose: To perform a systematic review and meta-analysis and to assess the clinical benefit of prophylactic pelvic drain (PD) placement after robot-assisted laparoscopic prostatectomy (RALP) with pelvic lymph node dissection (PLND) in patients with localized prostate cancer. Materials and Methods: An electronic search of databases, including Scopus, Medline, and EMbase, was conducted for articles that considered postoperative outcomes with PD placement and without PD (no drain) placement after RALP. The primary outcome was rate of symptomatic lymphocele (requiring intervention) and secondary outcomes were complications as described by the Clavien-Dindo classification system. Quality assessment was performed using the Modified Cochrane Risk of Bias Tool for Quality Assessment. Results: Six relevant articles comprising 1783 patients (PD = 1253; ND = 530) were included. Use of PD conferred no difference in symptomatic lymphocoele rate (risk difference 0.01; 95% confidence interval [CI] -0.007 to 0.027), with an overall incidence of 2.2% (95% CI 0.013-0.032). No difference in low-grade (I-II; risk difference 0.035, 95% CI -0.065 to 0.148) or high-grade (III-V; risk difference -0.003, 95% CI -0.05 to 0.044) complications was observed between PD and ND groups. Low-grade (I-II) complications were 11.8% (95% CI 0-0.42) and 7.3% (95% CI 0-0.26), with similar rates of high-grade (III-V) complications, being 4.1% (95% CI 0.008-0.084) and 4.3% (95% CI 0.007-0.067) for PD and ND groups, respectively. Conclusion: PD insertion after RALP with extended PLND did not confer significant benefits in prevention of symptomatic lymphocoele or postoperative complications. Based on these results, PD insertion may be safely omitted in uncomplicated cases after consideration of clinical factors.

BDNF val66met genotype and schizotypal personality traits interact to influence probabilistic association learning.

The brain derived neurotrophic factor (BDNF) val66met polymorphism rs6265 influences learning and may represent a risk factor for schizophrenia. Healthy people with high schizotypal personality traits display cognitive deficits that are similar to but not as severe as those observed in schizophrenia and they can be studied without confounds of antipsychotics or chronic illness. How genetic variation in BDNF may impact learning in individuals falling along the schizophrenia spectrum is unknown. We predicted that schizotypal personality traits would influence learning and that schizotypal personality-based differences in learning would vary depending on the BDNF val66met genotype. Eighty-nine healthy adults completed the Schizotypal Personality Questionnaire (SPQ) and a probabilistic association learning test. Blood samples were genotyped for the BDNF val66met polymorphism. An ANOVA was performed with BDNF genotype (val homozygotes and met-carriers) and SPQ score (high/low) as grouping variables and probabilistic association learning as the dependent variable. Participants with low SPQ scores (fewer schizotypal personality traits) showed significantly better learning than those with high SPQ scores. BDNF met-carriers displaying few schizotypal personality traits performed best, whereas BDNF met-carriers displaying high schizotypal personality traits performed worst. Thus, the BDNF val66met polymorphism appears to influence probabilistic association learning differently depending on the extent of schizotypal personality traits displayed.
