[The solitary rectal ulcer today. A review of the literature].

The solitary rectal ulcer (SRU) is a benign lesion of adults of either sex, which presents with chronic constipation, peculiar defecatory disorders, rectal prolapse and smaller psychological abnormalities. The characteristic appearance of this disease is a "neither being always ulcerate, nor always solitary" lesion, but often with polypoid or granular feature, typically localized in anterior rectal wall, a few inches from anal channel. Distinctive histopathological specimens are localized mucosal distortion, hypertrophic proliferation of muscularis mucosae and obliteration of lamina propria by fibroblasts and muscle fibres from the muscularis mucosae. Very few intermittent or recurrent symptoms are rectal bleeding and mucous discharge with defecations, difficulty of a complete ampullar evacuation and sometimes pelvic or rectoperineal pain. Clinical picture and endoscopic biopsies led to diagnosis. Barium enema, defecography, transrectal ultrasound, manometry and electromyography have an additional role. Medical treatment is performed by high-fiber diet, but biofeedback training is very helpful. Surgical management is as an excisional surgery, as a rectopexy if there is prolapse. Fecal diversion and rectocolic resection are considered only for patients with obstinate and severe symptoms. Even in patients who seem to advocate a surgical approach it is important to heal a dyskinetic puborectalis muscle.

Lateral discoid meniscus: treatment and results.

Forty-six patients (47 knees) who had symptomatic discoid lateral menisci were operated on between August 1981 and May 1989. The patients were categorized according to Watanabe's classifications: complete (80.8%), incomplete (10.6%), and Wrisberg type (8.5%). The treatment of the discoid meniscus is based on total or partial meniscectomy, achieved by the percutaneous or arthrometric technique. Of the 47 knees, 30 underwent a follow-up evaluation. Using Ikeuchi's knee scale, 27 cases (90%) had either excellent or good ratings, and 3 (10%) received fair ratings. There were no poor outcomes. The results in the knees treated by partial meniscectomy were better than those in the knees treated with total meniscectomy.

Osteoid osteoma of the spine.

After reviewing the international literature the authors present three new cases of osteoid osteoma with vertebral body localisation, two in the lumbar region, and one in the cervical region. This rare localisation necessitates the use of accurate instrumental techniques, based on radiography, scintigraphy, and in particular, CT scanning, in order to arrive at a correct diagnosis as a prelude to the correct surgical treatment.
