The clinical [corrected] background of familial adenomatous polyposis. History, epidemiology, diagnosis and treatment.
Familial adenomatous polyposis (FAP) is a dominantly inherited genetic disorder predisposing to colon cancer through the early development of multiple adenomatous polyps in the large bowel. FAP is not restricted to the colon and rectum, but is a more complex disease which can potentially affect almost any organ not only with benign tumours but also with life threatening carcinomas. Desmoid tumours and gastroduodenal polyps and cancer are the two more worrying extracolonic manifestations of FAP. Recent advances in FAP knowledge, such as the report of congenital hypertrophy of the retinal pigment epithelium (CHRPE) or the APC gene identification, are very useful for screening and long-term follow-up of the patients through regional or national registries. Nutritional and pharmacological intervention trials are under way to assess potential new medical treatments of FAP. Surgery is still the only effective treatment for colorectal cancer prevention in FAP. The choice of a surgical procedure is controversial, but the introduction of total proctocolectomy with ileal pouch-anal anastomosis can be considered as a major advance in surgical treatment of FAP during the last decade.

Role of cytokines in inflammatory bowel disease.
The authors review the recent literature about the proinflammatory role of interleukins-1,-2,-6,-8, tumour necrosis factor and interferon-gamma in Crohn's disease and ulcerative colitis, as well as their possible use to assess disease activity and to design new therapeutic approaches. Most cytokines were secreted in excess in inflammatory bowel disease. An imbalance between interleukin-1 and interleukin-1 antagonist might be a factor responsible of the chronicity of intestinal lesions. Circulating levels of interleukin-2 receptor are related to disease activity. Preliminary data on the therapeutic use of antibodies to tumour necrosis factor are encouraging.

[Hemorrhoids. Review].
Correct definition of haemorrhoidal disease allows the estimation of the incidence and the therapeutic choices. The term "haemorrhoidal disease" should be used specifically for symptoms secondary to abnormalities of the intern haemorrhoidal plexus. The classification of severity is useful but difficult to apply to individual cases. The aetiopathogenesis remains unclear. Many arguments are in favour of a progressive degeneration of the fibromuscular structure of the internal haemorrhoidal plexus responsible for his prolapse in the anal canal. Most patients suffering from haemorrhoids are relieved by simple dietary advice. Moderate prolapsing haemorrhoids are significantly improved by rubber band ligation. Surgical haemorrhoidectomy remains the procedure of choice in patients with advanced prolapsing haemorrhoids.

Perianal condylomata acuminata.
Anal and perianal condylomata acuminata are warts caused by infection with the human papillomavirus (HPV). The annual incidence of genital warts seems to have increased during the past few decades. Approximately 1.5 million consultations per year take place in the United States with this condition (1). Papillomavirus is a sexually transmitted disease, and is associated with several other venereal infections as well as with intraepithelial neoplasia and invasive squamous carcinoma. Only certain genotypes of HPV are carcinogenic, and can be precisely identified by in situ hybridisation techniques. There are many therapeutic alternatives, possibly reflecting the wide variability in treatment response.
