Cerebral potentials evoked by electrical stimulation of the anal canal.

We describe the procedure with which cortical potential responses are evoked by a stimulation of the anal canal to assess the integrity of its sensory pathways. These potentials were recorded in 66 patients. In 44 patients, a cortical evoked response was obtained with a succession of positive and negative peaks, W shaped (35 cases) or V shaped (nine cases).

[Hiccup caused by epigastric compression in a hemiplegic patient].

The authors report the case of a patient with permanent, refractory hiccup, resistant at all classical treatment methods. Hiccup was due to compression of the epigastric region by the left fist of the patient immobilised by a spastic hemiplegia. Passive mobilisation of the diseased upper limb resulted in the disappearance of hiccup.

Anal ulcerations due to cytomegalovirus in patients with AIDS. Report of six cases.

Lesions due to cytomegalovirus (CMV) are frequent in the immunocompromised patient. This is particularly the case in patients with AIDS, where the colon and rectum are the regions most often involved. The authors report six cases of anal ulcerations due to CMV in patients with AIDS.

Rectal stenosis due to Veganine suppositories.

A new case of rectal stenosis due to the chronic use of suppositories of associated analgesic drugs is reported. Surgical treatment was conservative. This observation outlines the dramatic consequences of chronic self-treatment and the difficulties of ensuring long-term withdrawal.
