BACKGROUND CONTEXT: Unrecognized and inadequately repaired intraoperative durotomies may lead to cerebrospinal fluid leak, pseudomeningocele, and other complications. Few studies have investigated durotomy that is unrecognized intraoperatively and requires additional postoperative management (hereafter, late-presenting dural tear [LPDT]), though estimates of LPDT range from 0.6 - 8.3 per 1,000 spinal surgeries. These single-center studies are based on relatively small sample sizes for an event of this rarity, all with <10 patients experiencing LPDT...

Perinephric urinomas commonly arise following traumatic injury or high grade obstruction from kidney stones or lower urinary tract disorders. Not only are spontaneous urinomas rare in the pediatric population, but malignancy presenting with perinephric urinomas have only been described in the adult population. In this case report, we report flank pain from a spontaneous perinephric urinoma as the presenting symptom of lymphoma in a pediatric patient.

BACKGROUND: Indoleamine-2,3-dioxygenase (IDO) catalyzes the first step of tryptophan (Trp) catabolism, yielding kynurenine (Kyn) metabolites. The kynurenine-to-tryptophan (K/T) ratio is used as a surrogate for biological IDO enzyme activity. IDO expression is increased during Escherichia coli urinary tract infection (UTI). Thus, our objective was to develop a method for measurement of Kyn/Trp ratio in human blood and urine and evaluate its use as a biomarker of UTI. METHODS: A mass spectrometric method was developed to measure Trp and Kyn in serum and urine specimens...

PURPOSE: Conservative treatment strategy without antibiotics in patients with uncomplicated diverticulitis (UD) has proven to be safe. The aim of the current study is to assess the clinical course of UD patients who were initially treated without antibiotics and to identify risk factors for treatment failure. METHODS: A retrospective cohort study was performed including all patients with a CT-proven episode of UD (defined as modified Hinchey 1A). Only non-immunocompromised patients who presented without signs of sepsis were included...

Congenital aphallia is a rare anomaly with little supporting literature and controversial management. The aim of this review is to assess the most recent literature with a focus on staged management of these cases. We performed a PubMed search of all English literature in the past 10 years using the term aphallia. Twenty-three articles were identified of which six were excluded. A further three papers meeting our criteria were found in the references to papers initially identified. We found that management can be staged in three phases: short, intermediate and long-term...

OBJECTIVE: Healthcare-associated infections (HAIs) after subarachnoid hemorrhage (SAH) are prevalent; however, data describing epidemiology of infection is limited. This study reports incidence rates, risk factors and the resulting SAH patient-related outcomes. METHODS: We studied the incidence of ICU-acquired HAIs over a 6-year period. We used Bayesian Model Averaging to identify risk factors associated with an increased risk of HAIs, particularly urinary tract infections (UTI), pneumonia and ventriculostomy-associated infections (VAI)...

Timely determination of antimicrobial susceptibility for a bacterial infection enables precision prescription, shortens treatment time and helps minimize the spread of antibiotic resistant infections. Current antimicrobial susceptibility testing (AST) methods often take several days and thus impede these clinical and health benefits. Here, we present an AST method by imaging freely moving bacterial cells in urine in real time and analyzing the videos with a deep learning algorithm. The deep learning algorithm determines if an antibiotic inhibits a bacterial cell by learning multiple phenotypic features of the cell without the need for defining and quantifying each feature...

In the mammalian lower urinary tract, there is a reciprocal relationship between the contractile state of the bladder and urethra. As the bladder fills with urine, it remains relaxed to accommodate increases in volume, while the urethra remains contracted to prevent leakage of urine from the bladder to the exterior. Disruptions to the normal contractile state of the bladder and urethra can lead to abnormal micturition patterns and urinary incontinence. While both the bladder and urethra are smooth-muscle organs, they are differentially contracted by input from cholinergic and sympathetic nerves, respectively...

AIM: To examine putative interaction between adrenergic and muscarinic contractile activation in the human urinary outflow tract. METHODS: Tissue from the trigone and prostatic urethra was obtained from 12 cystectomy and 16 prostatectomy specimen. Contractions were elicited by exposure to exogenous agonists before and after inhibition of Rho kinase and protein kinase c (PKC). Immunofluorescence and Western-blot studies were performed using antibodies to muscarinic M3-receptors (M3-R) and alpha1A-adrenoreceptors (alpha1A-AR)...

REVIEW
Young R Lee, Nathaniel T Baker
Meropenem-vaborbactam is a carbapenem and β-lactamase inhibitor combination that is newly indicated for the treatment of complicated urinary tract infections (cUTI), including adult pyelonephritis. Vaborbactam was developed due to emergence of carbapenem-resistant strains of Enterobacteriaceae. In a phase I trial, patients that received meropenem-vaborbactam 2-2 g intravenously over 3 h every 8 h, Cmax was 58.2 ± 10.8 μg/mL for meropenem and 59.0 ± 8.4 μg/mL for vaborbactam. AUC0-8 was 186 ± 33...

Chronic prostatitis (CP) is a clinically common disease with high morbidity. It affects the patients' quality of life (QoL) as well as physical and mental health seriously due to the recurring symptoms of lower urinary tract and genitalia. As the opinions about the etiology of CP are still not uniform, it is very difficult to be treated or even cured. Autophagy is a highly conserved physiological function which is widely found in eukaryotic cells. In general, cells maintain a certain level of autophagy under physiological conditions, and the basal level of autophagy can be regulated by a variety of autophagy-related genes under stress such as hunger, infection, trauma, and other circumstances...

A 54-year-old woman was admitted to hospital with a presumed allergic reaction to a single dose of amoxicillin given for a suspected upper respiratory tract infection. She complained of chest tightness although there was no wheeze or stridor. On examination, she was pyrexial, tachycardic, hypertensive and had a diffuse mottled rash on her lower limbs. Her initial investigations showed raised inflammatory markers. She was treated in the intensive care for a presumed anaphylactic reaction with an underlying sepsis...

Selenium, a trace element to which humans are exposed mainly through diet, has been involved in the etiology of human cancer. We investigated the long-term effects of selenium exposure on cancer incidence using data from a natural experiment in Northern Italy. During the 1970s-1980s, in a part of the Italian municipality of Reggio Emilia, residents were inadvertently exposed to unusually high levels of inorganic hexavalent selenium (selenate) through drinking water. We followed the exposed residents for 28years, generating data on incidence (when available) and mortality rates for selected cancer sites; the remaining municipal residents comprised the unexposed (reference) group...

BACKGROUND: The World Health Organization estimates the prevalence of preterm birth to be 5-18% across 184 countries of the world. Statistics from countries with reliable data show that preterm birth is on the rise. About a third of neonatal deaths are directly attributed to prematurity and this has hindered the achievement of Millennium Development Goal-4 target. Locally, few studies have looked at the prevalence of preterm delivery and factors associated with it. This study determined the prevalence of preterm birth and the factors associated with preterm delivery at Kenyatta National Hospital in Nairobi, Kenya...
