Hypothermia in multiple sclerosis.

Five patients with clinically definite multiple sclerosis are reported who presented with acute relapses associated with hypothermia. Repeated episodes of hypothermia were seen in four. Thrombocytopenia was associated with the hypothermia in four patients. Further investigation disclosed a tendency to chronic hypothermia and suggested an altered thermoregulatory set point in one patient, when MRI, endocrine, and autonomic studies failed to localise a lesion in the hypothalamus, but subsequent necropsy showed hypothalamic lesions. In such patients a predisposition to altered thermoregulation may occur due to direct involvement of the hypothalamus or from combined lesions affecting hypothalamic outflow to the brainstem and spinal cord.

Steroids in multiple sclerosis.

Steroids are widely used in treating the relapse of multiple sclerosis. There is no place for long term steroid therapy of this disease. Current practice is a short course of high dose methylprednisolone which can be repeated after an interval, has proven safety and objectively accelerates recovery.

Methylprednisolone in multiple sclerosis: a comparison of oral with intravenous therapy at equivalent high dose.

A randomised double-blind placebo-controlled trial of intravenous methylprednisolone versus oral methylprednisolone at equivalent high dose was carried out on 35 patients with an acute relapse of multiple sclerosis (MS). After baseline evaluation each was randomly allocated to oral treatment and intravenous placebo or intravenous treatment and oral placebo, receiving 500 mg of methylprednisolone for five consecutive days and with reassessment at days five and twenty-eight. There was no significant difference in response when disability or functional scores were compared in the two groups. Adverse effects were minor and equally distributed. In this study oral treatment with methylprednisolone was as effective as intravenous treatment in acute relapse of MS.

Epilepsy and employment. A community based survey in an area of high unemployment.

A community based survey was undertaken to assess the work record of patients with epilepsy in an area of high unemployment. One hundred and thirty seven epileptic patients were identified from a population of 23,837 persons of employable age registered with three urban group practices in North East England. The unemployment rate for economically active patients with epilepsy was 46% compared with 19% for an age and sex matched control population (p less than 0.01). Fifty nine per cent of patients with active epilepsy were unemployed. In those with an associated neurological or psychiatric handicap and those who were unskilled manual workers the unemployment rates were 79% and 77%, respectively. Patients with epilepsy were less likely to leave school with qualifications or undergo subsequent training or apprenticeships. They were more likely to be unskilled manual workers, single and living in rented accommodation. In an area of high unemployment patients with epilepsy have disproportionately greater difficulty finding work. High unemployment rates among patients with epilepsy are only one aspect of a spectrum of social and economic disadvantage.

Hashimoto's encephalopathy: a steroid-responsive disorder associated with high anti-thyroid antibody titers--report of 5 cases.

We describe 5 patients with a relapsing encephalopathy in association with Hashimoto's disease and high titers of anti-thyroid antibodies. The presentation is usually with a subacute onset of confusion, alteration in conscious level, and focal or generalized seizures. The relapsing course, association with myoclonus or tremulousness, and episodes of stroke-like deterioration are characteristic features. The long-term prognosis is favorable with steroid therapy, though additional immunosuppressive therapy may be required. Neurologic investigation typically shows a diffusely abnormal EEG, high CSF protein level without pleocytosis, and normal brain CT and cerebral angiogram. Isotope brain scan may show patchy abnormal uptake. Hashimoto's encephalopathy should be recognized as a definite neurologic entity and added to the list of CNS complications of thyroid disease.

Intravenous methylprednisolone for multiple sclerosis in relapse.

A randomised comparison is made between methylprednisolone, 1 g intravenously daily for 7 days, and a standard ACTH regime for the treatment of multiple sclerosis in acute relapse. It is found that methylprednisolone produces a more rapid clinical improvement than ACTH but confers no longer term benefit when the two treatments are compared at 3 months. It is proposed that intravenous methylprednisolone does have a role to play in the management of a patient with an acute relapse of multiple sclerosis.

Delayed encephalopathy following cardiac arrest.

A 46 year old woman suffered a post-operative cardiac arrest associated with prolonged depression of oxygenation and respiration. She made a good initial recovery but one year later insidiously developed symptoms of widespread central nervous system damage compatible with a delayed post-hypoxic encephalopathy. This case is unusual in the length of time between the hypoxic insult and the later deterioration and also illustrates other atypical features of a delayed post-hypoxic syndrome.
