Aerococcus sanguinicola and Aerococcus urinae are emerging pathogens in clinical settings mostly being causative agents of urinary tract infections (UTIs), urogenic sepsis and more seldomly complicated infective endocarditis (IE). Limited knowledge exists concerning the pathogenicity of these two species. Eight clinical A. sanguinicola (isolated from 2009 to 2015) and 40 clinical A. urinae (isolated from 1984 to 2015) strains from episodes of UTIs, bacteremia, and IE were whole-genome sequenced (WGS) to analyze genomic diversity and characterization of virulence genes involved in the bacterial pathogenicity...

Intestinal microbiota disruption is associated with acute gastrointestinal (GI) Graft-versus-Host Disease (GvHD) and poor outcome after allogeneic stem cell transplantation (ASCT). Here, in a retrospective analysis of 200 patients undergoing ASCT at the Regensburg University Medical Center, we assessed the relative expression of Paneth cell antimicrobial peptides (AMPs), Human Defensins (HD) 5 and 6 and regenerating islet-derived 3α (Reg3α), in 292 human intestinal biopsies as well as Reg3α serum levels in relation to acute GI GvHD...

Asymptomatic bacteriuria (ASB) is benign except in certain medical conditions such as pregnancy and immunosuppression. In Ghana, there are hardly any studies on urinary infections among sickle cell disease (SCD) patients, and the few studies carried out in Africa focused on pediatric SCD populations. The current study aimed to investigate the risk of ASB among SCD patients at a tertiary hospital in Ghana. This was a cross-sectional study involving 110 SCD patients and 110 age and sex matched healthy controls...

Urolithiasis can result as a complication of urinary diversión, favored by urinary stasis, intestinal mucus, urinary tract bacteriuria, the metabolic derangements and the presence of foreign bodies. We present a 52- year-old male who underwent radical cystectomy with construction of a Bricker uretero-ileostomy. 5 years later he was found with a forgotten ureteral stent, a 6 cm calculi occupying the whole ileal conduit and a 13 mm calculi in the left renal pelvis. We present our experience in the successful endourological management of an encrusted neglected ureteral stent in an ileal conduit, achieving a stone-free status without complications...

Polymicrobial infections constitute small ecosystems that accommodate several bacterial species. Commonly, these bacteria are investigated in isolation. However, it is unknown to what extent the isolates interact and whether their interactions alter bacterial growth and ecosystem resilience in the presence and absence of antibiotics. We quantified the complete ecological interaction network for 72 bacterial isolates collected from 23 individuals diagnosed with polymicrobial urinary tract infections and found that most interactions cluster based on evolutionary relatedness...

OBJECTIVE: To report survival for patients who undergo urinary diversion for benign indications and to identify risk factors for morbidity at 90 days. METHODS: This is a retrospective review of consecutive urinary diversions with or without cystectomy for non-oncological indications at a single institution. The indication for diversion was intractable incontinence, upper tract deterioration, urinary fistula, and unmanageable bladder pain. Patients were categorized according to their most severe complication within 90 days of surgery, using the Clavien-Dindo system...

OBJECTIVES: To assess the role of TEO/TEM in recto-urethral fistulas (RUF). RUF may appear after radical prostatectomy. Their treatment represents a challenge; many therapies have been proposed, from conservative to aggressive surgical approaches. Transanal endoscopic surgery (TEO/TEM) is a minimally invasive technique to access the site of the RUF to perform repair. METHODS: Observational study with prospective data collection, conducted between September 2006 and December 2015...

Although currently still the gold standard treatment for post-prostatectomy urinary incontinence, the artificial urinary sphincter (AUS) (AMS800) is an invasive procedure with associated risks factors. In this paper, we aim to outline what the scientific literature and what we personally believe are the factors that are useful and/or necessary to mitigate these risks, including both patient factors and surgeon factors. We also review special populations, including transcorporal (TC) AUS approach, AUS with inflatable penile prosthesis, AUS after male urethral sling, AUS erosion management, and AUS after orthotopic urinary diversion...

Urolithiasis is a well-known and common late complication in patients with urinary diversion. Patients without urinary diversion lead to symptoms such as hematuria and ureteral colic, whereas stones in patients with urinary diversion tend to be asymptomatic and are often diagnosed incidentally during staging examinations of oncologic diseases. We report the case of a 64-year-old male patient with a lower pole kidney stone and a stone in the ileal ureter substitution. He presented with diffuse abdominal and left-sided flank pain...

Down syndrome (DS) is often associated with cardiac malformations, so that kidney damage is little known. The objective of this study was to present the diversity of renal abnormalities and their potential progression to chronic renal failure. Among congenital abnormalities of the kidney and urinary tract (CAKUT) abnormalities appear to be frequent: pyelectasis, megaureters, posterior urethra valves, as well as renal malformations such as renal hypoplasia, horseshoe kidney, or renal ectopia. Contributing factors to acute kidney failure have been described in patients with DS: bilateral lesions and minor renal injury, such as glomerular microcysts, tubular dilation, and immature glomeruli...

The clinical application of platelet-rich plasma (PRP) is based on the increase in the concentration of growth factors that are released from alpha-granule of the concentrated platelets and in the secretion of proteins which are able to capitalize on the healing process at the cellular level. It has been invented to restore the natural beauty by starting the natural rejuvenation process of the skin and aiming to make it function as a younger one and to keep the skin youthful and maintain it. Besides that, it is also emerged to include hairs as a new injectable procedure to enable stimulating hair growth locally and topically; preventing its fall; improving hair shaft, hair stem, and its caliber; increasing its shine, vitality, and pliability; and declining hair splitting and breakage...

BACKGROUND: Urinary tract obstruction and postoperative hydronephrosis are risk factor for renal function deterioration after orthotopic ileal neobladder construction. However, reports of relationship between transient hydronephrosis and renal function are limited. We assess the influence of postoperative transient hydronephrosis on renal function in patients with orthotopic ileal neobladder construction. METHODS: Between January 2006 and June 2013, we performed radical cystectomy in 164 patients, and 101 received orthotopic ileal neobladder construction...
