A cavernous sinus cavernous hemangioma. Case report

The case of a Turner's syndrome patient with an intracavernous hemangioma is presented. The rarity of this lesion is stressed, as is surgical removal without postoperative deficit, the role of estrogens in the pathogenesis, and the clinical and radiological findings.

A pharmacokinetic and pharmacodynamic study of a 'visiting pill' containing norethisterone

The pharmacokinetics and pharmacodynamic effects of two doses of norethisterone (5mg and 3mg) used as a 'visiting pill' were investigated. There were no significant differences in the pharmacokinetics of the two doses except for the peak concentration achieved and the bioavailability as assessed by the area under the serum norethisterone concentration - time curve. Both doses were rapidly absorbed. Pharmacodynamic effects were minor. No change occurred in serum concentrations of total cholesterol, total triglycerides or HDL-cholesterol. The area under the serum glucose concentration--time curve and particularly the area under the serum insulin concentration--time curve were significantly increased as a result of treatment but no change occurred in the serum levels of glycosylated haemoglobin. SHBG concentrations in serum decreased on treatment whereas those of ceruloplasmin increased.

Sudden death in a patient with Von Recklinghausen's neurofibromatosis

Sudden death caused by tumors is uncommon. Death attributable to an unsuspected primary intracranial neoplasm is especially rare. An undiagnosed brain tumor is particularly unusual in a patient with Von Recklinghausen's neurofibromatosis (NF). A young man with known NF, with no manifest central nervous system involvement, died less than 24 hours after plastic surgery. A glioblastoma multiforme was discovered at autopsy.
