Common anorectal conditions.

Patients with a wide variety of anorectal lesions present to family physicians. Most can be successfully managed in the office setting. A high index of suspicion for cancer should be maintained and all patients should be questioned about relevant family history or other indications for cancer screening.

Common anorectal conditions: Part II. Lesions.

Patients with a wide variety of anorectal lesions present to family physicians. Most can be successfully managed in the office setting. A high index of suspicion for cancer should be maintained and all patients should be questioned about relevant family history or other indications for cancer screening.

Common anorectal conditions: Part I. Symptoms and complaints.

Anorectal symptoms and complaints are common and may be caused by a wide spectrum of conditions. Although most conditions are benign and may be successfully treated by primary care practitioners, a high index of suspicion for colorectal cancer should be maintained, and all patients should be appropriately investigated. Inspection, palpation and anoscopic examination using an Ive's slotted anoscope provide adequate initial assessment.

G(E(p))/G(M(p)) ratio by polarization transfer in e-->p --> ep-->.

The ratio of the proton's elastic electromagnetic form factors, G(E(p))/G(M(p)), was obtained by measuring P(t) and P(l), the transverse and the longitudinal recoil proton polarization, respectively. For elastic e-->p-->ep-->, G(E(p))/G(M(p)) is proportional to P(t)/P(l). Simultaneous measurement of P(t) and P(l) in a polarimeter provides good control of the systematic uncertainty.

Perineal repair of colorectoanal intussusception. Report of a case and review of the literature.

Colorectoanal intussusception is a rare and distinct entity that differs from the more common rectal prolapse. Typically intussusception occurs with tumor at the apex of the intussuscepted segment acting as a lead point. Only 26 adult cases of this entity have been reported in the literature.
