Using 2D differential gel electrophoresis (DIGE) and mass spectrometry (MS), a recent report by Rattan and Ali (2015) compared proteome expression between tonically contracted sphincteric smooth muscles of the internal anal sphincter (IAS), in comparison to the adjacent rectum [rectal smooth muscles (RSM)] that contracts in a phasic fashion. The study showed the differential expression of a single 23 kDa protein SM22, which was 1.87 fold, overexpressed in RSM in comparison to IAS. Earlier studies have shown differences in expression of different proteins like Rho-associated protein kinase II, myosin light chain kinase, myosin phosphatase, and protein kinase C between IAS and RSM...

BACKGROUND: Laparoscopic resection of colorectal cancer is widely used. However, robust evidence to conclude that laparoscopic surgery and open surgery have similar outcomes in rectal cancer is lacking. A trial was designed to compare 3-year rates of cancer recurrence in the pelvic or perineal area (locoregional recurrence) and survival after laparoscopic and open resection of rectal cancer. METHODS: In this international trial conducted in 30 hospitals, we randomly assigned patients with a solitary adenocarcinoma of the rectum within 15 cm of the anal verge, not invading adjacent tissues, and without distant metastases to undergo either laparoscopic or open surgery in a 2:1 ratio...

INTRODUCTION: Anal fissures are a common cause of anal pain during, and for 1 to 2 hours after, defecation. The cause is not fully understood, but low intake of dietary fibre may be a risk factor. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of surgical treatments for chronic anal fissure? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review)...

Anal fissure is an ulceration of the anoderm in the anal canal. Its pathogenesis is due to multiple factors: mechanical trauma, sphincter spasm, and ischemia. Treatment must address these causative factors. While American and British scientific societies have published recommendations, there is no formal treatment consensus in France. Medical treatment is non-specific, aimed at softening the stool and facilitating regular bowel movements; this results in healing of almost 50% of acute anal fissures. The risk of recurrent fissure remains high if the causative factors persist...

Sexual medicine experts and sexologists must spread certainties on the biological basis of the female orgasm to all women, not hypotheses or personal opinions. Therefore, they must use scientific anatomical terminology. The anatomy of the clitoris and the female orgasm are described in textbooks, but some researchers have proposed a new anatomical terminology for the sexual response in women. The internal/inner clitoris does not exist: the entire clitoris is an external organ. The clitoris is not composed of two arcs but of the glans, body, and crura or roots...

Discovery of pruritus-specific mediators and receptors facilitated the neurobiological concept of pruritus: itch-specific (histamine-dependent and histamine-independent C-fibers); itch-specific receptors on cutaneous and spinal neurons; "dialogue" between the pruritus-specific neurons and cells in the skin; peripheral and central mediation of pruritus; functional "pruritus-specific matrix" in the brain with a role of pruritus center. In 10%-50% of persons without skin diseases, pruritus is considered the manifestation of a systemic disorder...

BACKGROUND: The internal anal sphincter (IAS) is a major contributing factor to pressure within the anal canal and is required for maintenance of rectoanal continence. IAS damage or weakening results in fecal incontinence. We have demonstrated that bioengineered, intrinsically innervated, human IAS tissue replacements possess key aspects of IAS physiology, such as the generation of spontaneous basal tone and contraction/relaxation in response to neurotransmitters. The objective of this study is to demonstrate the feasibility of implantation of bioengineered IAS constructs in the perianal region of athymic rats...

Muscle replacement for patients suffering from extensive tissue loss or dysfunction is a major objective of regenerative medicine. To achieve functional status, bioengineered muscle replacement constructs require innervation. Here we describe a method to bioengineer functionally innervated gut smooth muscle constructs using neuronal progenitor cells and smooth muscle cells isolated and cultured from intestinal tissues of adult human donors. These constructs expressed markers for contractile smooth muscle, glial cells, and mature neuronal populations...
