This study aimed to investigate the expression and function of BKCa channels in the Sphincter of Oddi (SO) in a rabbit model of hypercholesterolemia (HC). New Zealand white rabbits were randomly divided into two groups: the control group was fed standard chow (n = 18) whereas the high-cholesterol group was fed cholesterol-enriched chow containing 1.5% cholesterol (n = 18). The serum cholesterol level was significantly greater in the HC groups than in the control group, but there was no significant difference in body weight between the control and HC groups...

AIMS: The pathophysiological mechanism of incontinence is multifactorial. We evaluated the role of 3D-4D ultrasound in the assessment of the fascial supports of the urethra and the urethral sphincter complex (USC) for diagnosing stress urinary incontinence. METHODS: Observational case-control study in women with and without stress urinary incontinence attending a urogynecology service and a general gynecology service. All women were interviewed, examined, and classified according to the Pelvic Organ Prolapse Quantification (POP-Q) and underwent a 3D-4D translabial ultrasound...

AIM: To determine the anatomical organization and somatic axonal components of the lumbosacral nerves in female rabbits. METHODS: Chinchilla adult anesthetized female rabbits were used. Anatomical, electrophysiological, and histological studies were performed. RESULTS: L7, S1, and some fibers from S2 and S3 form the lumbosacral trunk, which gives origin to the sciatic nerve and innervation to the gluteal region. From S2 to S3 originates the pudendal nerve, whose branches innervates the striated anal and urethra sphincters, as well as the bulbospongiosus, ischiocavernosus, and constrictor vulvae muscles...

Sphincter of Oddi dysfunction is caused by stenosis or dyskinesia of the sphincter of Oddi, leading to blockage of bile drainage from the common bile duct. We present the case of a 16-year-old female with chronic abdominal pain who underwent laparoscopic cholecystectomy for cholelithiasis but continued to experience abdominal pain, nausea, and vomiting along with persistently elevated ALT and AST levels. Postoperative abdominal ultrasound was nondiagnostic. Esophagogastroduodenoscopy showed mild reflux esophagitis and mild chronic Helicobacter pylori-negative gastritis...

This study evaluated the 4-year results of 32 patients with T1N0 low-lying rectal adenocarcinoma treated solely with californium-252 (Cf-252) neutron intracavity brachytherapy (ICBT). Patients were solicited into the study from January 2008 to June 2011. All the patients had refused surgery or surgery was contraindicated. The patients were treated with Cf-252 neutron ICBT using a novel 3.5-cm diameter off-axis 4-channel intrarectal applicator designed by the authors. The dose reference point was defined on the mucosa surface, with a total dose of 55-62 Gy-eq/4 f (13-16 Gy-eq/f/wk)...

Urinary incontinence is a widespread problem for women, with stress urinary incontinence (SUI) being the most common type. An updated review of PubMed literature using the following keywords was performed: stress urinary incontinence, women, midurethral slings, bulking agents, pubovaginal slings, retropubic suspension, postoperative complications, and treatment outcome. More recent publications, systematic reviews, and meta-analyses were given preference. The aging population will increase the demand for care of women with SUI...

Pelvic fracture urethral injuries (PFUI) commonly result from motor vehicle collisions. The mechanism of injury conventionally thought was a shearing injury at the membranous urethra, which would destroy the striated sphincter. Continence would therefore depend on the bladder neck. Striated sphincter and site of injury has not been shown clearly on preoperative imaging. We demonstrate a our protocol of performing MRI whereby the membranous sphincter is seen intact and the injury is shown to be at the membrano-bulbar junction contrary to conventional belief...

BACKGROUND: Cauda equina syndrome is a rare disorder that causes loss of Lumbar plexus function (nerve roots) lower than conus medullaris. No risk factor has been defined for this disease yet. Due to the high morbidity of Cauda equina syndrome and lack of sufficient information about the connection between the disease and urodynamic findings and EMG (Electromyography) findings, the need for this comprehensive study is felt. OBJECTIVE: The aim is to determine the predictive power of findings resulted from urodynamics and electromyography of perineal region and around sphincter in the clinical cure rate of urination in patients with urinary retention followed by Cauda equina syndrome...

Here we report a case of surgical pupilloplasty in an adult with true polycoria. A 44-year old man was referred to our clinic with a best-corrected visual acuity (BCVA) of 0.5 diopters (D) in his left eye. Biomicroscopy revealed two pupils within a 2.5-mm central zone, with diameters of 1.2 and 1.1 mm. Both pupils had real iris sphincters and responded to light and chemical stimulation. Therefore, we surgically cut the bridge between the two pupils without any intraoperative or postoperative complications. One month after the surgery, BCVA had improved to 0...

Anoscrotal fistula is an extremely rare condition involving an epithelialised tract between the anal canal and scrotal wall. It is more commonly seen as a congenital phenomenon in the paediatric population, and has not previously been described in the literature in adults. We present the case of a man aged 52 years who developed a complex anoscrotal fistula after a radical inguinal orchidectomy for an intratesticular seminoma. A postsurgical wound-site infection developed into a chronically discharging wound refractory to antibiotic treatment prompting further investigation...

In tropical countries, laboratory-confirmed diagnostic certainty of parasitic and other infectious causes of acute myelopathy is difficult because of a shortage of medical professionals and consulting delays. We performed a retrospective study of 168 patients hospitalized for spinal disorders between 2007 and 2013 and identified 26 diagnosed with acute non-compressive myelopathy of presumed sudden onset. An parasitic or other infectious cause was established for all. A preliminary clinical infection preceding the development of neurologic signs was reported for 22 patients (84...

BACKGROUND: Several studies have described the course and anatomical relations of the pudendal nerve. Several surgical nerve decompression techniques have been described, but only the transgluteal approach has been validated by a prospective randomized clinical trial. The purpose of this study was to describe the course of the nerve and its variants in a population of patients with pudendal neuralgia in order to guide the surgeon in the choice of surgical approach for pudendal nerve decompression...

Purpose Squamous cell carcinoma of the anal canal (SCCAC) is characterized by high locoregional failure (LRF) rates after sphincter-preserving definitive chemoradiation (CRT) and is typically associated with anogenital human papilloma virus infection. Because cetuximab enhances the effect of radiation therapy in human papilloma virus-associated oropharyngeal squamous cell carcinoma, we hypothesized that adding cetuximab to CRT would reduce LRF in SCCAC. Methods Sixty-one patients with stage I to III SCCAC received CRT including cisplatin, fluorouracil, and radiation therapy to the primary tumor and regional lymph nodes (45 to 54 Gy) plus eight once-weekly doses of concurrent cetuximab...

BACKGROUND AND AIMS: Biopsy of the ampulla of Vater may be performed to evaluate for ampullary adenomas, suspected ampullary tumors and immunohistological staining for autoimmune pancreatitis. Ampullary biopsies are commonly performed at the time of endoscopic retrograde cholangiopancreatography (ERCP). Due to the well-established complication rate following ERCP, the contribution of ampullary biopsy as a potential independent risk factor would require a controlled comparison. METHODS: A matched-pairs, case-control analysis was performed for patients undergoing ERCP with or without ampullary biopsy...

Maher Zaiem, Feras Zaiem
INTRODUCTION: Posterior sagittal anorectoplasty (PSARP) published by DeVries and Peña in 1982 had become the preferred surgical technique for the management of anorectal malformations (ARM). The original technique is based upon complete exposure of the anorectal region by means of a median sagittal incision that runs from the sacrum to the anal dimple, cutting through all muscle structures behind the rectum by dividing the levator muscle and the muscle complex. Then, the rectum is located in front of the levator and within the limits of the muscle complex...

INTRODUCTION: Although preoperative negative urine culture results and treatment of urinary tract infections are generally advised before artificial urinary sphincter (AUS) and penile prosthesis (PP) surgery to prevent device infection, limited evidence exists to support this practice. AIM: To evaluate the relation between preoperative urine culture results and the bacteriology of prosthetic device infections. METHODS: Men undergoing AUS and/or PP placement at a tertiary referral center from 2007 through 2015 were analyzed...
