Introduction The aim of this study was to determine the prevalence of GBS colonization in pregnant women in a public health service. Methods A study of 496 pregnant women at 35-37 gestational weeks was conducted from September 2011 to March 2014 in 21 municipalities of the 18th Health Region of Paraná State. Vaginal and anorectal samples of each woman were plated on sheep blood agar, and in HPT...
We report the case of a patient referred to our prenatal diagnostic unit due to the suspicion of spina bifida at 24 weeks gestation. Morphological assessment revealed rachischisis associated with Chiari type II, single kidney and anorectal malformation. The nonvisualization of the anal sphincter complex (ASC) on ultrasound led to the diagnosis of suspected high-type anorectal malformation (A,B ...
The ultrastructural features of the internal anal sphincter (IAS) muscle were studied in biopsies from five patients with neurogenic anorectal incontinence and six control subjects undergoing anorectal excision for cancer, or for inflammatory bowel disease. In the patients with idiopathic neurogenic anorectal incontinence the internal anal sphincter showed loss of smooth muscle cells, disruptio...
introduction: rectal prolapse refers to extrusion of mucosa or the full thickness wall of the rectum through the anal sphincter, which is more common between infancy and 4 years of age and has a high incidence in the first year of life. it is considered as a sign of an underlying clinical condition causing an increased intra‑abdominal pressure, pelvic floor weakness or poor root innervations as...
This review aimed to critically evaluate the literature on the efficacy of biofeedback for functional anorectal disorders, rate these biofeedback applications according to established guidelines, and make recommendations for this field based on the literature. The Medline and PsychInfo databases were searched to obtain all papers published from 1975 to 2003 that included the terms "biofeedback"...
The mechanics of defecation and fecal continence are poorly understood. Valvular theories for continence 2 rely on raised intra-abdominal pressure to force the anterior wall of the rectum downwards to close off the anorectal junction. Such theories are not consistent with EMG and radiological data which suggest a striated muscle sphincteric mechanism.3 It has been demonstrated that puborectalis...
BACKGROUND Previous studies showed that C. trachomatis strains found in MSM are different from those in heterosexuals. This study investigates whether the differences in strain distribution between MSM and heterosexuals are due to tissue tropism. METHODS C. trachomatis positive samples were collected from MSM (anorectal) and women (anorectal, cervical, vaginal, pharyngeal) visiting the STI ou...
We have identified an ethylnitrosourea (ENU)-induced recessive mouse mutation (Vcc) with a pleiotropic phenotype that includes cardiac, tracheoesophageal, anorectal, anteroposterior patterning defects, exomphalos, hindlimb hypoplasia, a presacral mass, renal and palatal agenesis, and pulmonary hypoplasia. It results from a C470R mutation in the proprotein convertase PCSK5 (PC5/6). Compound muta...
CONTEXT AND OBJECTIVE Anorectal malformations comprise a spectrum of anomalies that continue to be difficult to treat, even today. The aim was to evaluate the fecal continence of children who underwent posterior sagittal anorectoplasty due to anorectal malformations, via computerized anorectal manometry and profilometry. DESIGN AND SETTING Prospective study at Universidade Federal de São Paul...
