Adult Mesenchymal Hamartoma of the Liver: Case Report and Literature Review

Mesenchymal hamartoma of the liver (MHL) is a rare benign lesion occurring primarily in the pediatric population. While the precise pathogenesis of the tumor is not certain, the most common theory relates to aberrant mesenchyme development in the portal tract likely related to the bile ducts. A 53-year-old female was evaluated for an incidental liver mass. Initial CT scan showed a cystic lesion in the right lobe of the liver and follow-up imaging revealed an increase in size and the percent solid component within the mass. In view of these changes, a nondiagnostic biopsy was obtained followed by extirpation of the lesion. Gross pathological review of the lesion identified a 9 × 9 × 7.5 cm, pink-yellow-tan, gelatinous mass, with a >1 cm clear surgical margin. Histologically, the mass consisted of benign dilated bile ducts, as well as myxoid stroma with spindle cells showing smooth muscle differentiation. The patient was discharged home on postoperative day five. A review of the literature for MHL in adults reports 30 previous cases, predominantly published as individual case reports describing the size, lobe(s) of the liver affected, and the cystic/solid nature of the tumor. MHL in adults may represent a potentially premalignant lesion, as the emerging literature supports a potential relationship between MHL and malignant undifferentiated embryonal sarcoma in regards to cytogenetic analysis. Aggressive surgical management of MHL in adults is mandated when feasible

Uro-oncology in the era of social distancing : the principles of patient-centered online consultations during the COVID-19 pandemic

The COVID-19 pandemic poses significant challenges to healthcare facilities and as per social distancing measures, many consultations are now being carried out via means of telemedicine. As some urologists may not be skilled with remote consultations, there is a need for recommendations on patient-centered online medical counseling. We have identified eight areas of excellence and defined the principles based on our experience. A professional setting should be provided, in which the privacy of the patient can be ensured. Accompanying persons should be encouraged into the consultation. Proper introduction could serve not only to verify the personality of the patient, but also to provide them with a sense of confidentiality. The interview should be held in a way to overcome the limitations of non-physical encounters, and pande-mic-specific issues should be taken into consideration. When arranging plans, the physician should judge accordingly in regards to what type of management is inevitable or safe, as well as available at this point; strict follow-up should be arranged. As home isolation may lead to unfavorable changes in lifestyle, this issue should be addressed too. The patient should be guided on how to self-educate. Concluding the visit should be aimed at proper evaluation of the patient's comprehension of the consultation. It is vital to pursue consistency in providing care to patients. While online counseling may seem challenging, if one adheres to the principles of patient-centered practice, telemedicine may become a valuable tool in maintaining the best-quality care amid the ongoing pandemic

Twitter and Academic Urology in the United States and Canada: A Comprehensive Assessment of the Twitter-verse in 2019.

OBJECTIVE: To provide the first comprehensive analysis of the Twitter-verse amongst academic urologists and programs in North America. METHODS: Using national accreditation and individual program websites, all active urology residency programs (USA & Canada) and academic Urology faculty at these programs were identified. Demographic data for each program (AUA section, resident class size) and physician (title, fellowship training, Scopus H-index and citations) were documented. Twitter metrics (Twitter handle, date joined, # tweets, # followers, # following, likes) for programs and physicians were catalogued (data capture: March-April 2019). Descriptive analyses and temporal trends in Twitter utilization amongst programs and physician were assessed. Multivariable (MV) logistic regression was used to identify predictors of Twitter use. RESULTS: 156 academic programs (143 USA, 13 Canada) and 2214 academic faculty (2015 USA, 199 Canada) were identified. Twitter utilization is currently 49.3% and 34.1% amongst programs and physicians, respectively, and continues to increase. On MV analysis, programs with 3-5 residents/year and programs with a higher percentage of faculty Twitter engagement were more likely to have Twitter accounts. From a physician perspective, those with fellowship training, lower academic rank (clinical instructor, assistant professor, associate professor vs. professor) and higher H-indices were more likely to have individual Twitter accounts. CONCLUSION: There is a steady increase in Twitter engagement amongst Urology programs and academic physicians. Faculty Twitter utilization is an important driver of program Twitter engagement. Twitter SoMe activity is strongly associated with academic productivity, and may in fact drive academic metrics. Within Urology, SoMe presence appears to be proportional to academic activity

Systematic review and meta-analysis on trimodal therapy versus radical cystectomy for muscle-invasive bladder cancer: Does the current quality of evidence justify definitive conclusions?

OBJECTIVES To systematically review and meta-analyze the current literature in a methodologically rigorous and transparent manner for quantitative evidence on survival outcomes among patients diagnosed with muscle-invasive bladder cancer that were treated by either trimodal therapy or radical cystectomy. MATERIALS AND METHODS MEDLINE, EMBASE, CENTRAL were systematically searched for comparative observational studies reporting disease-specific survival and/or overall survival on adult patients diagnosed with localized muscle-invasive bladder cancer that were exposed to either trimodal therapy or radical cystectomy. Studies qualified for meta-analysis (random effects model) if they were not at critical risk of bias (RoB). RESULTS The literature search identified 12 eligible studies. Three (all rated as "moderate RoB") out of 6 studies reporting on disease-specific survival qualified for quantitative analysis and yielded a pooled hazard ratio (trimodal therapy versus radical cystectomy) of 1.39 (95% confidence interval: 1.03-1.88). Four (mainly rated as "serious RoB") out of 12 studies were included in the meta-analysis of overall survival and estimated a hazard ratio of 1.39 (1.20-1.59). CONCLUSION Pooled results were significant in favor of radical cystectomy. The conclusion is mainly driven by large population-based studies that are at high RoB. Hence, the certainty of these treatment estimates can be considered very low and further research will likely have an important impact on these estimates. At present, the ultimate decision between trimodal therapy and radical cystectomy should be left to the patient based on individual preferences and on the recommendation of a multidisciplinary provider team experienced with both approaches

Setting the Standards: Examining Research Productivity Among Academic Urologists in the USA and Canada in 2019.

BACKGROUND: Research productivity among academic urologists is strongly encouraged, but little data are available on productivity metrics within the field. OBJECTIVE: To provide the first comprehensive survey of research productivity among academic urologists in the USA and Canada. DESIGN, SETTING, AND PARTICIPANTS: Using the Accreditation Council for Graduate Medical Education, the Canadian Resident Matching Service, and individual program websites, all active accredited urology faculties were identified. For each individual, we collected data on American Urological Association section, title, gender, fellowship training, Scopus H-index, and citations. Comprehensive searches were completed during March-May 2019. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Descriptive statistics for demographic comparisons were performed using analysis of variance for continuous variables and chi-square test for categorical variables. Multivariable logistic regressions were used to identify the predictors of H-index greater than the median. RESULTS AND LIMITATIONS: A total of 2214 academic urology faculties (2015 in USA and 199 in Canada) were identified. The median and mean H-indices for the entire cohort of physicians were 11 and 16.1, respectively. On multivariable analysis, physicians in the North Central and Western Sections (vs mid-Atlantic), who were fellowship trained (vs no fellowship training), and of higher academic rank (professor and associate professor vs clinical instructor) were more likely to have H-index values greater than the median. Additionally, female physicians (vs male) were more likely to have H-index values less than the median. CONCLUSIONS: This study represents the first comprehensive assessment of research productivity metrics among academic urologists. These represent key benchmarks for trainees considering careers in academics and for practicing physicians gauging their own productivity in relation to their peers. PATIENT SUMMARY: In this study, we provide the first comprehensive assessment of research productivity among academic urologists in the USA and Canada. Our results help provide key benchmarks for trainees considering careers in academics and for practicing physicians gauging their own productivity in relation to peers

Comparison of MRI- and TRUS-Informed Prostate Biopsy for Prostate Cancer Diagnosis in Biopsy-Naive Men: A Systematic Review and Meta-Analysis.

PURPOSE: Multiparametric magnetic resonance imaging (mpMRI) with informed targeted biopsies (TGBX) has changed the paradigm of prostate cancer (PCa) diagnosis. Randomized studies have demonstrated a diagnostic benefit of Clinically significant (CS) for TGBX compared to standard systematic biopsies (SBX). We aimed to evaluate whether mpMRI-informed TGBX has superior diagnosis rates of any-, CS-, high-grade (HG)-, and clinically insignificant (CI)-PCa compared to SBX in biopsy-naive men. METHODS: Data was searched in Medline, Embase, Web of Science, and Evidence-based medicine reviews-Cochrane Database of systematic reviews from database inception until 2019. Studies were selected by two authors independently, with disagreements resolved by consensus with a third author. Overall 1951 unique references were identified, and 100 manuscripts underwent full-text review. Data were pooled using random-effects models. The meta-analysis is reported according to the PRISMA statement. The study protocol is registered with PROSPERO (CRD42019128468). RESULTS: Overall 29 studies (13,845 patients) were analyzed. Compared to SBX, use of mpMRI-informed TGBX was associated with a 15% higher rate of any PCa diagnosis (95% CI 10-20%, p\u3c0.00001). This relationship was not affected by the study methodology (p=0.11). Diagnosis of CS and HG PCa were more common in the mpMRI-informed TGBX group (risk difference of 11%, 95% CI 0-20%, p=0.05, and 2%, 95% CI 1-4%; p=0.005, respectively) while there was no difference in diagnosis of CI PCa (risk difference of 0, 95% CI -3-3%, p=0.96). Notably, the exclusion of SBX in the mpMRI-informed TGBX arm significantly modified the association between a mpMRI strategy and lower rates of CI PCa diagnosis (p=0.01) without affecting the diagnosis rates of CS- or HG-PCa. CONCLUSIONS: In comparison to SBX, a mpMRI-informed TGBX strategy results in a significantly higher diagnosis rate of any-, CS-, and HG-PCa. Excluding SBX from mpMRI-informed TGBX was associated with decreased rates of CI-PCa diagnosis without affecting diagnosis of CS- or HG-PCa
