International Anal Neoplasia Society's consensus guidelines for anal cancer screening.

The International Anal Neoplasia Society (IANS) developed consensus guidelines to inform anal cancer screening use among various high-risk groups. Anal cancer incidence estimates by age among risk groups provided the basis to identify risk thresholds to recommend screening. Guided by risk thresholds, screening initiation at age 35 years was recommended for men who have sex with men (MSM) and transgender women (TW) with HIV.

Chlamydia trachomatis anorectal infections by LGV (L1, L2 and L2b) and non-LGV serotypes in symptomatic patients in Buenos Aires, Argentina.

Background: (CT) can infect the anorectum producing various signs and symptoms. There is scarce literature regarding the differences between LGV and non-LGV CT anorectal manifestations. We compare the clinical spectrum of LGV and non-LGV infections.

Rectal Lymphogranuloma Venereum, Buenos Aires, Argentina.

Among 34 men with proctitis in Buenos Aires, Argentina, 16 (47%) had Chlamydia trachomatis infection, 11 (68.8%) of which were biovar lymphogranuloma venereum. The outbreak was probably local, as in Europe.

[Clinical polymorphism of anorectal lymphogranuloma venereum in Buenos Aires City].

From 2003 to date there has been a rising number of reports from developed countries on cases of lymphogranuloma venereum with anorectal localization in HIV-infected men who have sex with men. This localization differs from the classical inguinal abscesses which are typical of the disease in the tropics. The objective of this work is to document the presence of anorectal lymphogranuloma venereum in Buenos Aires and to describe its varied clinical manifestations.

[Sacral neuromodulation. Long-term results].

Sacral neuromodulation involves electrical stimulation of af­ferent nerve roots to restore the balance between inhibitory and excitatory reflexes who improve the functional activity of the pelvic floor. With benefits in patients with fecal inconti­nence, constipation and chronic anorectal pain. Objective.

[Total anorectal reconstruction after proctocolectomy: surgical results and functional outcome].

The aim of this report is to describe a novel technical approach to total anorectal reconstruction and show surgical results and functional outcome. The technique is an innovative surgery to restore gastrointestinal perineal continuity after coloproctectomy in patients with familial adenomatous polyposis. We made the internal anal sphincter replacement with demucosated small bowel plication, the external anal sphincter replacement with an artificial bowel sphincter (ABS) and the restitution of intestinal transit with and ileal "S" pouch.

[Perianal Kaposi's sarcoma. A case report and a review of the literature].

Kaposi's sarcoma is the most common cancer in men who have sex with men with AIDS. The estimated prevalence in the United States is 25% in patients with positive serology for the human immunodeficiency virus (HIV). The commitment of the gastrointestinal tract is seen in 40% of patients with Kaposi's sarcoma related to AIDS but lesions can occur anywhere in the body and evolve rapidly.

[Anorectal manometry and ultrasound in the study of patients with fecal incontinence].

Introduction: Fecal incontinence is a complex disease that affects the quality of life of patients suffering from it. Anorectal manometry and endoanal ultrasound 360 grades are included among the studies used. There are no clear agreement about the relevance and usefulness of this studies and their role as apart of diagnostic procedures.

[Prospective, double-blind study of topical phenylephrine treatment for nocturnal fecal incontinence in patients after ileoanal pouch construction].

Patients: Fecal incontinence has been reported in 5.5% to 45% of patients after ileoanal pouch construction, predominantly at night. It has been shown that alpha1-adrenergic agonists as phenylephrine increase anal sphincter pressure in healthy volunteers and in patients with idiopathic fecal incontinence.

[Sacral neuromodulation in fecal incontinence. A pilot prospective experience in Argentina].

Introduction: Anal incontinence is a severe physical and emotional condition that affects quality of life. Its treatment with neuromodulation, that consists in sacral roots electrical stimulation, has became a therapeutic option.

Objective: This study was designed to present the surgical technique and the first prospective experience in neuromodulation for fecal incontinence in Argentina.
