[Thyroid disease and multiple autoimmune syndromes. Clinical and immunogenetic aspects apropos of 11 cases].

The authors report eleven cases of multiple auto-immune syndrome, concerning a total of 15 different auto-immune diseases. This study suggests that auto-immune thyroid disorders (Graves' disease or hypothyroidism resulting from Hashimoto's thyroiditis) are a common feature of multiple auto-immune syndromes, while antithyroid antibodies are constant among our patients. Sjögren's syndrome is also very prevalent, and seems to be non-randomly associated with auto-immune thyroid disorders, a fact which suggests common aetiological factors. Among other auto-immune disorders, the antiphospholipid syndrome has been diagnosed twice. A genetic predisposition to multiple auto-immune syndrome is obvious, as shown by a familial history of auto-immune disorders (found in more than half of the cases), and a predominant HLA phenotype, B8 and/or DR3. The authors plead for a systematic enquiry for multiple auto-immune syndrome in patients with auto-immune thyroid disorders and a family history of auto-immune disorders.

Long-lasting antinociceptive effect of RC-160, a somatostatin analog, in mice and rats.

The effect of RC-160 (D-Phe-Cys-Tyr-D-Trp-Lys-Val-Cys-Trp-NH2) was studied in mice by means of the hot plate test and in rats with the tail flick test. In mice, 512 micrograms/kg (s.c.) induced an antinociceptive effect maximal (+88 +/- 17%) at the 6th hour after injection but still significant at the 24th hour; 16 micrograms/kg (s.c.) was active for 3 h; 64, 256 and 1024 micrograms/kg were active 30 min, 3 and 24 h after injection. The effects of these last three doses were not different. The antinociceptive action was as high at 24 h as at 3 h (e.g. for 512 micrograms/kg, 44 +/- 9% and 51 +/- 12%, respectively); 48 h after injection the scores of the treated groups were not different from the score for saline treatment in the tail flick test, 512 micrograms/kg induced a significant antinociceptive effect for 12 h (maximal at the 3rd hour: +60%). No behavioral changes, and particularly no motor activity modifications were observed.

[Neurologic manifestations of basal cell nevomatosis. A case].

The naevoid basal cell syndrome, also called Gorlin's syndrome, is a dysembryoplasia akin to the phakomatoses and which may affect the skin, the bones, the nervous system, the eyes, the endocrine glands and the genitalia. A case with numerous tumours and malformations is presented, together with a review of the literature.

A comparison of the effects of vitamin B12 and aspirin in three experimental pain models in rats and mice.

The effects of vitamin B12 are compared to those of aspirin and 0.9% saline in three different experimental pain models in rats and mice; an electric shock test, the hot-plate test, and the phenylbenzoquinone writhing test. Neither cyanocobalamin nor hydroxocobalamin showed any antinociceptive activity in any of the three tests at any of the doses used, whether the drug was administered as a single injection or as a series of daily injections lasting 7 days. These results run counter to those of clinical trials in man, though close scrutiny of the experimental procedures used in these trials often reveals a lack of rigor which casts doubts on their validity. This consideration, together with the negative findings reported here, suggests that the clinical use of vitamin B12 as an analgesic may be inappropriate.
