RESUMO
OBJECTIVE: Music is a highly complex acoustic stimulus in both spectral and temporal contents. Accurate representation and delivery of high-fidelity information are essential for music perception. However, it is unclear how well bone-anchored hearing implants (BAHIs) transmit music. The study objective is to establish music perception performance baselines for BAHI users and normal hearing (NH) listeners and compare outcomes between the cohorts. METHODS: A case-controlled, cross-sectional study was conducted among 18 BAHI users and 11 NH controls. Music perception was assessed via performance on seven major musical element tasks: pitch discrimination, melodic contour identification, rhythmic clocking, basic tempo discrimination, timbre identification, polyphonic pitch detection, and harmonic chord discrimination. RESULTS: BAHI users performed comparably well on all music perception tasks with their device compared with the unilateral condition with their better-hearing ear. BAHI performance was not statistically significantly different from NH listeners' performance. BAHI users performed just as well, if not better than NH listeners when using their control contralateral ear; there was no significant difference between the two groups except for the rhythmic timing (BAHI non-implanted ear 69% [95% CI: 62%-75%], NH 56% [95% CI: 49%-63%], p = 0.02), and basic tempo tasks (BAHI non-implanted ear 80% [95% CI: 65%-95%]; NH 75% [95% CI: 68%-82%, p = 0.03]). CONCLUSIONS: This study represents the first comprehensive study of basic music perception performance in BAHI users. Our results demonstrate that BAHI users perform as well with their implanted ear as with their contralateral better-hearing ear and NH controls in the major elements of music perception. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:1381-1387, 2024.

The pediatric melanoma population is not well described, and current guidelines for their management are not well defined. Our study aims to identify this population, treatment modalities, and outcomes using a national population-based database. We reviewed the Surveillance, Epidemiology, and End Results database (2004-2008). Patients ≤21 years old with melanoma were included and grouped into ≤12 years of age, 13 to 18 years, and 19 to 21 years. Clinical characteristics were analyzed across the groups. A total of 1255 patients were included: 52.7 per cent were 19 to 21 years of age, 36.3 per cent were 13 to 18 years of age, and 11.0 per cent were ≤12 years of age. The 19- to 21-year-olds had the highest proportion of stage I (50.5%) versus ≤12 years of age (31.9%); the ≤12-year-olds had the highest proportion of stage IV (3.6%) versus 19 to 21 years of age (0.9%), P < 0.001. The 19- to 21-year-olds had the highest proportion receiving wide local excisions only (34.8%) versus ≤12 years of age (26.4%); the ≤12-year-olds had the highest proportion of patients without any surgeries (16.0%) versus 13 to 18 years of age (9.4%), P = 0.169. On adjusted analysis, the 19- to 21-year-olds had worse survival compared with ≤12 years of age (hazard ratio: 5.26, P = 0.017, 95% confidence interval 1.34-20.65). Disparities were found in the ≤12-year-old melanoma population, as they had later stage melanomas, less invasive surgery, and lower survival. Clearer prognostic factors are needed to better elucidate their management.

PURPOSE OF REVIEW: To review the current literature regarding the role of multiparametric MRI and fusion-guided biopsies in urologic practice. RECENT FINDINGS: Fusion biopsies consistently show an increase in the detection of clinically significant cancers and decrease in low-risk disease that may be more suitable for active surveillance. Although, when to incorporate multiparametric MRI into workup is not clearly agreed upon, studies have shown a clear benefit in both biopsy naïve and those with prior negative biopsies in determining the appropriate treatment strategy. More recently, cost-analysis models have been published that show that upfront MRIs are more cost-effective when considering missed cancers and treatment courses. SUMMARY: With improved accuracy over systematic biopsies, fusion biopsies are a superior method for detection of the true grade of cancer for both biopsy naïve and patients with prior negative biopsies, choosing appropriate candidates for active surveillance, and monitoring progression on active surveillance.

INTRODUCTION: The Open Payments Program was enacted to increase transparency of financial relationships between physicians and the medical device and pharmaceutical industry. We examined nonresearch related financial relationships between urologists and industry in the United States using the latest Open Payments data. METHODS: We performed a descriptive analysis of Open Payments data released by the Centers for Medicare and Medicaid Services for 2014. Total payment amounts associated with various urological drug and device categories were calculated. We then examined for correlations between payments and prescribing at the national level using Medicare Part D prescribing data. RESULTS: There were 232,207 payments totaling $32,418,618 made to 8,618 urologists (73.6% of practicing urologists in the United States) during calendar year 2014. Median payment was $15 (IQR $11 to $24). While the majority of individual payments (68%) were $20 or less, 82% of the urologists in the database received more than $100 from industry during 2014. The frequency of industry payments was positively correlated with Medicare Part D prescribing frequency as well as the sum of claims (r = 0.726, p = 0.005 and r = 0.755, p = 0.003, respectively). CONCLUSIONS: Nearly 75% of urologists in United States received nonresearch payments from industry in 2014. Most individual payments were for less than $20 but the majority of urologists received more than $100 in aggregate during the study year, with most of the money going toward speaker fees. Payments were positively correlated with Part D prescribing, yet confounding variables make it difficult to establish a cause and effect relationship.
RESUMO
PURPOSE: Population studies of patients undergoing radical cystectomy (RC) for bladder cancer (BC) suggest that a more extended lymph node dissection (LND) increases survival. However, information regarding LNDs of patients undergoing RC with a history of radiation therapy for BC is largely unknown. This study aims to define the lymph node yield (LNY) in patients undergoing RC for BC following radiation of the bladder using the surveillance epidemiology and end results (SEER) database. METHODS: Data were collected using SEER 18 registries from 1988 to 2013 to identify patients undergoing RC for BC. Data on extent and yield of LND were obtained. Logistic regression and multivariate Cox proportional hazard regression were done to identify predictors of adequate LND and all-cause mortality, respectively. RESULTS: In total, 27,451 patients were identified, of which, 27,362 (99.7%) were radiation naïve and 89 (0.3%) had prior radiation therapy for BC. The average LNY in radiation naïve patients (15, SD [13.5]) was slightly higher than the LNY in patients with prior radiation (12.3 SD [9.2], p = 0.157). Prior radiation was not an independent predictor of overall mortality (HR = 1.3, 95% CI [0.98-1.7]; p = 0.076). CONCLUSIONS: A lower proportion of patients with a history of radiation underwent a LND. The LNYs of radiation naïve patients, and those with a history of radiation, were not statistically different; however, the proportion of irradiated patients was small. Further investigation will be required to elucidate the patient and provider characteristics that contribute to the similar LNYs.

BACKGROUND: Extra-adrenal paragangliomas (PGLs) are infrequent, benign, and neuroendocrine tumors arising from chromaffin cells of the autonomic nervous system. Most PGLs are sporadic, but up to 32% are associated with inherited syndromes such as neurofibromatosis type 1, von Hippel-Lindau disease, and familial PGL. Although most PGLs develop above the umbilicus, they have been reported in the genitourinary (GU) tract. Owing to the paucity of literature on the rates of GU PGL, the objective of our study is to describe the demographic, pathologic, and clinical characteristics of GU PGL, and compare them to non-GU sites of PGL using the surveillance, epidemiology, and end results (SEER) database. METHODS: The SEER 18 database was used to identify all cases of PGL from 2000 to 2012. Demographic, pathologic, and clinical characteristics were described using chi-square and t-test for categorical and continuous variables, respectively. The Kaplan-Meier method was used to compare overall survival (OS) between GU and non-GU PGL. Statistical significance was defined as P<0.05. All analyses were performed using excel and SAS/Stat version 9.4. RESULTS: A total of 299 cases of PGL were retrieved from SEER, and 20 (6.7%) of the total PGL arose from the GU tract. The mean age at diagnosis was higher in non-GU than GU PGL (50.4±17.2 vs. 40.8±15.6, P = 0.026). Furthermore, 75% of GU PGLs developed in the bladder, followed by the kidneys/renal pelvis, and spermatic cord (20%). Non-GU PGL developed most frequently within the endocrine system (43%). PGL, overall, was more common in men than in women, and it was more common in whites than all other races. Although 55.5% of GU PGLs were organ confined, only 22.2% of non-GU PGLs were localized at diagnosis. All cases of PGL were treated with surgery. There were 2 cause-specific deaths in the GU PGL groups between 2000 and 2012. The 5-year OS was 93.3% for GU PGL vs. 65.5% in non-GU PGL (P = 0.062). CONCLUSIONS: GU PGL remains rare with low incidence (6.7% of all PGL cases) in the US population between 2000 and 2012. Bladder PGL represents just 5% of all PGL. Moreover, GU PGL had better OS compared to PGL developing outside of the GU tract although the P-value only approached statistical significance. The bladder represents the most common site of involvement, and surgery is the mainstay of treatment for GU PGL. Clearer prognostic factors, including tumor grade and stage, are needed to better elucidate PGL management in the future; thus, pooled studies from various institutions with detailed clinical information are needed to delineate these prognostic factors.

BACKGROUND: Weight regain has led to an increase in revision of Roux-en-Y gastric bypass (RYGB) surgeries. There is no standardized approach to revisional surgery after failed RYGB. We performed an exhaustive literature search to elucidate surgical revision options. Our objective was to evaluate outcomes and complications of various methods of revision after RYGB to identify the option with the best outcomes for failed primary RYGB. METHOD: A systematic literature search was conducted using the following search tools and databases: PubMed, Google Scholar, Cochrane Clinical Trials Database, Cochrane Review Database, EMBASE, and Allied and Complementary Medicine to identify all relevant studies describing revision after failed RYGB. Inclusion criteria comprised of revisional surgery for weight gain after RYGB. RESULTS: Of the 1200 articles found, only 799 were selected for our study. Of the 799, 24 studies, with a total of 866 patients, were included for a systematic review. Of the 24 studies, 5 were conversion to Distal Roux-en-y gastric bypass (DRYGB), 5 were revision of gastric pouch and anastomosis, 6 were revision with gastric band, 2 were revision to biliopancreatic diversion/duodenal switch (BPD/DS), and 6 were revision to endoluminal procedures (i.e., stomaphyx). Mean percent excess body mass index loss (%EBMIL) after revision up to 1 and 3-year follow-up for BPD/DS was 63.7 and 76 %, DRYGB was 54 and 52.2 %, gastric banding revision 47.6 and 47.3 %, gastric pouch/anastomosis revision 43.3 and 14 %, and endoluminal procedures at 32.1 %, respectively. Gastric pouch/anastomosis revision resulted in the lowest major complication rate at 3.5 % and DRYGB with the highest at 11.9 % when compared to the other revisional procedures. The mortality rate was 0.6 % which only occurred in the DRYGB group. CONCLUSION: All 866 patients in the 24 studies reported significant early initial weight loss after revision for failed RYGB. However, of the five surgical revision options considered, BPD/DS, DRYGB, and gastric banding resulted in sustained weight loss, with acceptable complication rate.

Malakoplakia, a medical, surgical, pathological and radiological enigma, is an infrequent chronic inflammatory condition that can affect many organ systems, including the gastrointestinal tract, integument, skeletal system and genitourinary tract. Review of the literature has shown that malakoplakia presents in paediatric as well as adult populations, and that it is associated with impaired immune function. Variable clinical manifestations as well as the sometimes non-specific radiological findings of malakoplakia can be misleading, making diagnosis quite difficult. We present a clinical case of renal malakoplakia mimicking a malignant renal carcinoma in a 62-year-old woman. This report highlights the importance of awareness of malakoplakia in the differential diagnosis for renal masses and renomegaly. This case can serve as a reminder that things are not always what they seem, and it reinforces the idea that unusual disease entities should be explored to aid in achieving a correct diagnosis and, thus, potentially avoid unnecessary treatment.

OBJECTIVE: To examine the impact of having a close relative experience a severe brain injury. DESIGN: Six-month longitudinal mixed methods concurrent embedded study. Quantitative data provided the primary database and qualitative data provided the secondary source. METHODS: Assessment included psychosocial factors of perceived stress, traumatic stress symptoms, coping and social support in addition to salivary cortisol as a biological marker of stress. Written accounts of the experience were provided in response to an open-ended question. Participants composed 15 close relatives of adults with severe brain injury admitted to a specialist rehabilitation facility (mean age 49.4 years; SD 11.79). Assessments were conducted on admission, at 6 weeks, 3 months and 6 months post-admission. RESULTS: Quantitative data revealed high traumatic stress at admission, with a non-significant decline at follow-up. Diurnal cortisol output declined significantly from baseline to all follow-up assessments. Coping sub-scales of acceptance and religion were repeated associated with cortisol indices at baseline, 6 weeks, 3 months and 6 months follow-up. Qualitative data revealed two themes; 'relational impact' and 'passage of time'. CONCLUSIONS: Findings offer the potential for effective and timely intervention in family members of persons with severe brain injury.
