Is familial hemiplegic migraine a hereditary form of basilar migraine?

We studied aura symptoms in 83 patients from 6 unrelated families suffering from familial hemiplegic migraine. Fifty-five of the patients reported symptoms that allowed us to categorize them as basilar migraine (BM) patients, in accordance with the International Headache Society (IHS) criteria. In a control group of 33 patients suffering from migraine with aura and 33 patients suffering from migraine without aura, 9 patients complained of vertigo, and only one patient of diplopia during one of her attacks.

Cerebrospinal fluid IgG and IgM indexes as indicators of active neurosyphilis.

Serological and non-serological tests were performed in matched samples of cerebrospinal fluid and serum from 236 syphilitic patients. An increased IgG or IgM index, or both, was found about 70 times more often in symptomatic neurosyphilis than in latent syphilis without involvement of the central nervous system. An increased Ig index, together with a cell count greater than 5/microL, was only found in symptomatic neurosyphilis.

Cells involved in the in vitro stimulation by DNP-carrier complexes of in vivo primed mouse spleen cells.

The target cell of stimulation of primed spleen cells by hapten—carrier complexes was studied. The antigens DNP—bovine serum albumin (DNP—BSA), which gives only 2,4-dinitrophenyl (DNP) specific responses and DNP—mouse immunoglobulin (DNP—MIg), which probably reveals DNP as well as carrier specificity (new antigenic determinant) were used. Educated T cells could be stimulated with the antigens used for activation.
