The traditional taxonomy of the genus Chloromyxum Mingazzini, 1890 has been intensively challenged to be paraphyletic by recent ribosomal DNA (rDNA)-based phylogenetic analysis. Undersampling to get rich sequence data to infer more scientific phylogenetic relationships makes scientists conservatively assign all non-marine elasmobranch-infecting species as Chloromyxum sensu lato. Although complex ridge pattern on the spore surface observed by scanning electron microscopy was thought to be critical for the identification of Chloromyxum species, insufficient data also prevent this ultrastructural data to be a valid taxonomic feature for this genus...

INTRODUCTION: Penetrating injuries to the pelvis and perineum can result in fistulas between the rectum and lower urinary tract. These injuries are often complicated, which creates challenges for successful repair. Operative strategies may include initial fecal and/or urinary diversion combined with an eventual trans-perineal, trans-anal, or posterior/transrectal approach, but the selected approach should be guided by precise anatomic localization of the injury. We aim to discuss different possible repair strategies as well as the relevant data surrounding gastrointestinal-genitourinary (GI-GU) fistula management...

PURPOSE: Reconstruction of complex functional structures is increasingly being performed with vascularized composite allo-transplantation (VCA). Penile transplantation is a novel VCA treatment option for severe penile tissue loss and disfigurement. Three allogeneic human penile transplantations have been reported. We review these cases as well as penile transplant indications, pre-clinical models, and immunosuppression therapy. MATERIALS AND METHODS: We performed a comprehensive literature review for the years 1970 to 2016 via MEDLINE, PubMed, and Google with the key words "penis transplantation", "penile rejection", "penile replantation", "penile tissue loss", and "penis vascularized composite allo-transplantation"...

INTRODUCTION: Interstitial cystitis is a debilitating condition that has a profound effect on quality of life. Although many approaches to treatment have been explored, no consistently effective treatment has been identified. Reconstructive surgery is offered to patients with refractory IC/BPS; however, expert opinion is divided as to whether simultaneous cystectomy is necessary to achieve symptomatic cure. The aim of this study was to report our experience in the surgical management of IC/BPS in a university teaching hospital...

Aerococci are Gram-positive cocci with colony morphology similar to viridans streptococci. Most often these isolates in clinical samples are misidentified and considered insignificant. However, with the use newer techniques like Matrix-Assisted Laser Desorption Ionization Time-of-Flight Mass-Spectrometry (MALDI-TOF MS), aerococci have been recognized as significant human pathogens capable of causing a diverse spectrum of infections. Among the different species of aerococci, Aerococcus urinae is the most common agent causing Urinary Tract Infection (UTI) followed by A...

Pyocystis, empyema cystis, vesical empyema are all terms that describe the purulent filled bladder that may develop in patients with defunctionalized bladders such as after supravesical urinary diversion without cystectomy or in patients with end-stage renal disease with anuria. It is a severe form of lower urinary tract infection. In addition to the local symptoms of suprapubic pain and malodorous discharge, the condition can be more serious with bacterial dissemination into the blood stream and ensuing sepsis and even mortality...

Urinary bladder cancer is known as a common cancer diagnosed across the world and results in significant mortality and morbidity rates among patients. The retinoblastoma (Rb) protein, as a main tumor suppressor, controls cellular responses to potentially oncogenic stimulation. Rb phosphorylation could disrupt E2F complex formation, resulting in diverse transcription factor dysfunction. In our study, we investigated how Rb is involved in controlling urinary bladder cancer progression. The results indicate that Rb expression is reduced in mice with urinary bladder tumor, and its suppression leads to urinary bladder cancer progression in vivo and in vitro...

Robotic-assisted radical cystectomy (RARC) represents an evolution of open radical cystectomy (ORC) with the aim of reducing patient morbidity and improving return to normal function, whilst maintaining oncological equivalence. RARC is gaining popularity, especially in high-volume centres, although there remains a lack of level 1 evidence to demonstrate any superiority of RARC over ORC. All previously reported studies that randomised ORC and RARC have utilised a technique for RARC requiring a conversion to open surgery for urinary diversion...
