The treatment of women with epilepsy.

BACKGROUND: Women with epilepsy and their doctors are often unsure of the implications of the disease and the limitations it causes. There is a major need for counseling. METHODS: Selective review of the literature as of November 2009. RESULTS: Recommendations on pregnancy and childbearing for women with epilepsy can be found in the guidelines issued by the German Societies of Neurology and Epileptology and by the American Epilepsy Society. Only low-level evidence is available on other relevant questions, including contraception, the influence of hormones on epilepsy, and the influence of antiepileptic drugs on endocrine and bone metabolism, because of a lack of controlled studies. Polycystic ovarian syndrome is more commonly seen in women with epilepsy who take valproate. Antiepileptic drugs that induce CYP3a can diminish the efficacy of oral contraceptives; conversely, oral contraceptives can markedly lower the blood levels of antiepileptic drugs. According to the most recent studies, the risk of congenital malformations and spontaneous abortions is 1% to 2% in the normal population and 3% to 9% in the offspring of women with epilepsy who are taking antiepileptic drugs. Women with epilepsy who want to have children are currently advised to take folic acid prophylactically starting before conception and until the end of the first trimester. New mothers with epilepsy are advised to breastfeed their children. CONCLUSION: Proper treatment and counseling of women with epilepsy, with due attention to aspects that are specific to women patients, can reduce the limitations to which they are subject in everyday life.

Autoimmune-mediated polyneuropathy triggered by borrelial infection?

A patient with proven borrelial infection of the central nervous system (CNS) and progressive weakness of the arms was treated with antibiotics. Although the initially elevated CXCL13 concentration in the cerebrospinal fluid decreased, indicating effective treatment of the infection, weakness progressed. Investigation revealed multiple nerve conduction blocks and the presence of GM1 antibodies, suggesting a multifocal motor neuropathy; the patient improved on treatment with intravenous immunoglobulins. This report of an autoimmune-mediated polyneuropathy in a patient with borrelial CNS infection indicates that such patients might respond to immunomodulatory therapy if antibiotic treatment is not effective.

Heart rate increase in otherwise subclinical seizures is different in temporal versus extratemporal seizure onset: support for temporal lobe autonomic influence.

Ictal heart rate was investigated in otherwise subclinical epileptic seizures to test the hypothesis as to whether ictal tachycardia is physiological and not a physical or psychological stress response. In addition, we aimed to evaluate the localizing significance of pure ictal tachycardia. We included 21 epilepsy patients, who showed an ictal EEG seizure pattern during 22, otherwise subclinical seizures. All patients underwent ictal video-EEG recordings to evaluate the possibility of resective epilepsy surgery. The changes in heart rate in these patients were investigated in order to determine their relationship to localization and duration of EEG seizure patterns. Ictal tachycardia was observed in 41% of the otherwise subclinical seizures (nine out of 22), and significantly more often in seizures arising from the temporal lobe than from extratemporal regions (62% versus 11%, p < 0.0018). The seizure duration as defined by EEG was significantly positively correlated with an increase of heart rate (p = 0.043). Ictal heart rate can increase as a result of epileptic activation of autonomic cortex, reflecting a temporal lobe autonomic influence. Thus, measurement of heart rate should be included in the evaluation of otherwise subclinical epileptic seizures, because of its localizing value.

Successful cardic surgery 24 hours after craniotomy in a patient with infective endocarditis and embolic cerebellar infarction: case report.

Follow up management in a patient already treated with decompressive craniotomy for a space-occupying endocarditic stroke is difficult. While immediate valve replacement eliminates the focus and therefore the high risk of re-embolization, a neurosurgical intervention is considered a contraindication to early cardiosurgery. Herein, the first report is presented of a critically ill patient with bacterial endocarditis and a space-occupying cerebellar infarction with imminent herniation, who successfully underwent mitral valve replacement only 24 h after decompressive craniotomy. To prevent rebleeding, maximal hemostasis was ensured during the neurosurgical intervention. For cardiosurgery, the patient was cooled to 21 degrees C, mildly hyperventilated, and maintained at an adequate perfusion pressure during cardiopulmonary bypass. A bioprosthesis was used to reduce the time of anticoagulation. The patient did not develop new infarcts after either intervention, and there was only a very small hemorrhagic transformation without a relevant mass effect. At five months after surgery the patient had minimal neurological abnormalities and was able to conduct his daily life without help.
