#1
Manuel Barbosa, Nuno Alves, Natacha Fontes
Perineal groove is a rare congenital anorectal malformation, with incidence yet undetermined. It is almost exclusive to the female newborn and its embryogenic origin remains uncertain. We present a case-report of a newborn girl that was discharged from the nursery without complications. At her first appointment at primary care we noted a wet sulcus connecting the posterior vaginal commissure and the anus. This case report emphasizes the rarity of the perineal groove and the importance of a good quality history and physical examination at primary care...

Biomechanical analysis of pelvic floor dysfunction requires knowledge of certain biomechanical parameters, such as muscle fiber direction, in order to adequately model function. Magnetic resonance (MR) diffusion tensor imaging (DTI) provides an estimate of overall muscle fiber directionality based on the mathematical description of water diffusivity. This work aimed at evaluating the concurrence between pubovisceralis muscle fiber representations obtained from DTI, and the maximum principal stress lines obtained through the finite element method...

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...

The association of diarrhea with diabetes mellitus has been known for more than 70 years. In diabetic patients its prevalence is around 20%.Its clinical manifestations are diverse, and represents a diagnostic and therapeutic challenge.There are certain diagnoses of higher prevalence in diabetic patients than in the general population.The different related etiologies can be adequately diagnosed through the clinical history and complementary diagnostic tests.The medications used by the diabetic patient to manage their disease often cause chronic diarrhea, so the pharmacological background should be studied at the time of the study of diarrhea...

The allosteric modulator 1-(4-chlorophenyl)-3-(3-(6-(pyrrolidin-1-yl)pyridin-2-yl)phenyl)urea (PSNCBAM-1, 2) bound the cannabinoid receptor 1 (CB1) and antagonized G protein coupling. This compound demonstrated potent anorectic effects similar to the CB1 antagonist rimonabant that once was marketed for the treatment of obesity, suggesting a new chemical entity for the discovery of antiobesity drugs. To increase structural diversity of this class of CB1 ligands, we designed and synthesized two classes of novel analogues, in which the pyridine ring of 2 was replaced by a pyrimidine ring...

BACKGROUND: Faecal incontinence (FI) is both a medical and social problem, with an underestimated incidence. For patients with internal anal sphincter damage, implantation of biomaterial in the anal canal is a recognised treatment option. One such material, Gatekeeper™, has previously shown promising short- and medium-term results without any major complications, including displacement. The main aim of the present study is to assess the degree to which displacement of Gatekeeper prostheses may occur and to determine whether this is associated with patient outcomes...
