Despite the hard times COVID-19 has imposed on us, the Biomedical Journal strives to provide fresh and compelling reading material - to be enjoyed safely from home. In this issue, we glance behind the scenes of dental stem cell preservation for potential therapeutic use, and discover that cancer cells hijack podoplanin expression to induce thrombosis. Moreover, we learn how the helicase DDX17 promotes tumour stemness, how genetic defects in meiosis and DNA repair cause premature ovarian insufficiency, and that the brain-derived neurotrophic factor is associated with several psychiatric diseases. Further accounts relate the role of miR-95-3p in colorectal cancer, the protective power of eggplants against mercury poisoning, and the predictive value of inhibin A for premature delivery. Finally, the very rare case of adenoid cystic carcinoma in the external auditory canal receives some attention, and we get to read up on how 3D imaging and modelling combines functional and aesthetic repair of cleft lip and palate cases. Neurocritical care is an approach of comprehensive care through multidisciplinary coordination and implementation of neuroprotective strategies to reduce the risk of neurologic injury among critically ill patients. Premature infants are at a special risk of sustaining brain injury and having adverse neurodevelopmental outcome. The pathogenesis of "encephalopathy of prematurity" is tightly linked to hemodynamic instability during postnatal transition, immaturity of the cerebral vascular bed and nervous system, and the commonly encountered inflammation in an intensive care setting. Clinical assessment aided by renewed monitoring techniques, together with therapies supported by best available evidence may provide opportunities to salvage these vulnerable brains. Indeed, to promote optimal brain development and to ensure neurodevelopmental intact survival is of imperial priority in the modern care of preterm infants. In the present study we analyze the epidemiological data of COVID-19 of Tibet and high-altitude regions of Bolivia and Ecuador, and compare to lowland data, to test the hypothesis that high-altitude inhabitants (+2,500 m above sea-level) are less susceptible to develop severe adverse effects in acute SARS-CoV-2 virus infection. Analysis of available epidemiological data suggest that physiological acclimatization/adaptation that counterbalance the hypoxic environment in high-altitude may protect from severe impact of acute SARS-CoV-2 virus infection. Potential underlying mechanisms such as (i) a compromised half-live of the virus caused by the high-altitude environment, and (ii) a hypoxia mediated down regulation of angiotensin-converting enzyme 2 (ACE2), which is the main binding target of SARS-CoV-2 virus in the pulmonary epithelium are discussed. V.OBJECTIVES To assess the incidence of delayed complications after robot-assisted simple prostatectomy and evaluate postoperative lower urinary tract symptoms (LUTS) as a function of time with intermediate-term follow-up. METHODS We retrospectively reviewed 150 patients who underwent robot-assisted simple prostatectomy between 5/2013 and 1/2019. Indication for surgery was bothersome LUTS refractory to medical management and prostate volume ≥80 milliliters. The severity of LUTS was assessed using the International Prostate Symptom Score (IPSS) and quality of life (QOL) score. One-way analysis of variance test with post-hoc Tukey's honest significant difference test was used to compare postoperative IPSS and QOL scores as a function of time; p0.05). CONCLUSIONS Robotic simple prostatectomy is associated with a low incidence of delayed complications at a mean of 31.3 months postoperatively. After robotic simple prostatectomy, urinary function outcomes improve in the early postoperative period with maximal improvement occurring at 3 months. Excellent urinary function outcomes are durable up to at least 36 months postoperatively. Urothelial cell carcinoma of the bladder is exceedingly rare in pediatric patients. Based on current literature, bladder cancer in this population is thought to be low-grade, noninvasive, and unlikely to recur, suggesting significant biologic differences when compared to the adult population. This is a 15-year-old male diagnosed with low-grade urothelial cell carcinoma with subsequent multifocal recurrence on surveillance cystoscopy managed by induction and maintenance intravesical Bacillus Calmette-Guerin. This case highlights the challenges of management and surveillance of this rare disease. Urethral duplication in a female is a rare congenital anomaly. The clinical presentation varies from being asymptomatic to double stream, incontinence, genital anomalies and urinary infections. The management is also tailor made to the clinical presentation. We describe a case of urethral duplication in an adult female who presented to us with clitoral voiding. A 17-year-old man with a history of imperforate anus presented to clinic with recurrent epididymitis. A fluoroscopic voiding cystourethrogram demonstrated urethra-ejaculatory duct reflux. A narrowing was also noted in the distal prostatic urethra with dilation of the proximal urethra. Subsequent cystoscopy revealed a patent urethra with a hypertrophic external sphincter as the culprit. Pelvic floor physical therapy was undertaken with resolution of urinary symptoms and testicular pain. We present a rare case of a 7 years old male with a perineal mass with Urethral duplication. [https://www.selleckchem.com/products/bgb-8035.html https://www.selleckchem.com/products/bgb-8035.html] Perineal mass histopathology showed colonic mucosa. The association of heterotopic colonic mucosa with urethral duplication, hypospadias, bifid scrotum and normal anus has not been described previously in the literature. OBJECTIVE To compare the accuracy of prostate sizing between pelvic abdominal (PUS) and transrectal (TRUS) ultrasound in a large, diverse cohort of men at our institution. Prostate volume plays a vital role in all types of prostate disease. AUA guidelines (2018) for surgical management of benign prostatic hyperplasia (BPH) now includes consideration of prostate volume measurement prior to surgical intervention. Ultrasound is a quick and radiation-free imaging modality. METHODS We performed a single-center, retrospective study of 299 patients with prostate sizing between January 1, 2012 and August 31, 2017. Prostate volume was derived from ellipsoid volume calculation using dimensions measured on ultrasound. PUS and TRUS were compared by calculating the Pearson correlation coefficient and ICC, and agreement between modalities assessed using the Bland Altman analysis. This analysis was done for the whole sample population as well as for specific groupings according to BMI, prostate size, and time between exams.
