  • Cancers of the Anus Cancers of the anus account for 1–2% of the malignant tumors of the large bowel. Most such lesions arise in the anal canal, the anatomic area extending from the anorectal ring to a zone approximately halfway between the pectinate (or dentate) line and the anal verge. Carcinomas arising proximal to the pectinate line (i.e., in the transitional zone between the glandular mucosa of the rectum and the squamous epithelium of the distal anus) are known as basaloid, cuboidal, or cloacogenic tumors; about one-third of anal cancers have this histologic pattern.

  • Standard treatment of anal cancer is a protocol of combined chemotherapy and radiotherapy. Typically, a diagnosis of LSIL results only in more frequent monitoring in case it progresses to HSIL. When HSIL is diagnosed, treatment may be called for to reduce the likelihood of progres- sion to cancer. This may include surgical removal of the lesions. Data on the efficacy of treatment are scarce. However, treatment of cervical lesions has been shown to be effective in substantially reducing the risk of progression to cancer....

  • Mucositis Irritation and inflammation of the mucous membranes particularly afflicting the oral and anal mucosa, but potentially involving the gastrointestinal tract, may accompany cytotoxic chemotherapy. Mucositis is due to damage to the proliferating cells at the base of the mucosal squamous epithelia or in the intestinal crypts. Topical therapies, including anesthetics and barrier-creating preparations, may provide symptomatic relief in mild cases.

  • Finally, research is needed to identify other groups that may benefit from anal screening, including women, and to document the efficacy of anal screening programs in lowering the incidence of anal cancer among those at risk. Widespread screenings of high risk groups may be a cost effective opportu- nity to prevent anal cancer and may well result in lower rates of this disease. Public health leaders should give serious consider- ation to encouraging bi-annual screening for all gay and bisexual men, and annual screen- ing for those gay and bisexual men who are living with HIV....

  • Bangladesh has no organized screening program, but recently the government decided to expand opportunistic VIA screening, making it one of the first countries to introduce VIA for its national cervical cancer screening program. 13 A report on this program14 announced that more than 100,000 women over 30 years of age had been screened, with a VIA positivity rate of less than 5 percent—a very low rate, which was attributed to extensive training and to the predominantly Muslim population. ...

  • The lack of understanding of the mechanisms whereby the above aetiological factors (genetic and environmental) interact to initiate the complex pathobiology of schizophrenia is the key reason for the relative lack of progress in the development of novel drug treatments. All the antipsychotic medication that is currently in use (first and second generation) is all predicated on the so-called ‘Dopamine Hypothesis’ (discussed below) and share a common putative mechanism of action, namely dopamine antagonism.

  • Infection with HPV is highly prevalent among gay and bisexual men. This population also has a high incidence of HPV-associated anal lesions and cancer. Gay and bisexual men living with HIV have an even higher inci- dence and progression of disease. This is similar to the story for cervical cancer. However, with strong advocacy and a concerted effort by researchers, clinicians, and public health leaders, dramatic reductions in the incidence of cervical cancer have been achieved.

  • Squamous cell carcinoma in situ, also called Bowen disease, is the earliest form of squamous cell skin cancer. “In situ” means that the cells of these cancers are still only in the epidermis and have not invaded the dermis. Bowen disease appears as reddish patches. Compared with actinic keratoses, Bowen disease patches tend to be larger (sometimes over 1/2 inch across), redder, scalier, and sometimes crusted. Like invasive squamous cell skin cancers, the major risk factor is too much sun exposure. Bowen disease can also occur in the skin of the anal and genital areas.

  • The efficacy of a screen-and-treat program is influenced not only by accuracy of the screening test but also by the ability of the treatment, in this case cryotherapy, to eliminate CIN2+ lesions identified by screening. While cryotherapy was highly successful in this trial, eliminating 75 to 77 percent of CIN2+ lesions, this was lower than previously reported 85 to 90 percent cure rates for clinical trials in developed countries and for less rigorous studies in developing regions.

  • Many recent studies have reported that microRNA (miRNA) biogenesis and function are related to the molecular mechanisms of various clinical diseases. Several methods, including northern blotting and DNA chip anal-yses, are capable of assessing miRNA-production patterns in cells. How-ever, the development of repetitive monitoring of the miRNA-production profile in a noninvasive manner is demanded for the application of miRNAs to human medicine.

  • Nowadays most Authors agree that preserving the rectum is useless, so it is sectioned at the level of anorectal junction. The preparation of the rectum toward anorectal junction is usually intramesorectal, which rises the risk of bleeding but also reduces the risk of nerve lesions. However mesorectal excision is mandatory in case of either severe dysplasia or cancer. After pouch construction, ileopouch-anal anastomosis can be either manual or stapled.
