POEMS syndrome.

A patient with peripheral polyneuropathy, hepatosplenomegaly, osteosclerotic myeloma in the ilium, hyperpigmentation and hypertrichosis is described. A diagnosis of POEMS syndrome was made. This is the first report of this syndrome from India.

Seizure susceptibility & intra rectal sodium valproate induced recovery in developing undernourished rats.

The seizure threshold and therapeutic potential of intrarectal sodium valproate were studied in young developing normal and undernourished rats, using the penicillin model. Undernourished rats were highly susceptible to seizure discharge. They exhibited generalised electrocortical inhibition and repeated episodes of epileptic discharges even after temporary neuronal recovery. Delayed spontaneous and drug induced neuronal recovery, low spike frequency and amplitude (P less than 0.001) reduced background EEG and marked electrocortical silence in response to intrarectal (25 mg/kg) sodium valproate treatment, was observed in the undernourished animals. Rehabilitated animals exhibited partial neuronal recovery which was related to the improvement in body weight. Analysis of spike frequency, spike amplitude and neuronal recovery time showed that both normal and undernourished animals behaved in a similar fashion at lower doses of penicillin (2.5 to 15 IU). Significant differences in the electrophysiological parameters were observed between the two groups at higher doses of penicillin (20 to 30 IU).

Pregnancy and epilepsy.

In a prospective study, 30 pregnant epileptic patients were followed through their pregnancy to determine the effect of seizures on pregnancy and its outcome and the effect of pregnancy on seizures. An attempt was made to correlate the serum hormone and anticonvulsant drug levels with seizure frequency, complications of pregnancy, occurrence of status epilepticus and teratogenicity. In 14 patients seizure frequency increased, in 15 it remained unchanged and in 1 patient it decreased. There were 2 spontaneous abortions, 2 patients had status epilepticus and 1 offspring of a patient had a ventricular septal defect. This patient was receiving carbamazepine and diphenylhydantoin. Patients with increased seizures frequency had significantly higher oestrogen levels, lower level of progesterone and lower level of anticonvulsant drugs as compared with those with no change in seizures. Patients who had abortions and those who developed status epilepticus had high serum oestrogen levels.

The heart in polymyositis-dermatomyositis.

Fourteen patients with polymyositis-dermatomyositis (PM-DM) underwent prospective cardiac assessment with non-invasive techniques. One patient had electrocardiographic evidence of Long-Ganong-Levine syndrome with multiple supraventricular premature beats. Echocardiographically one patient had late systolic prolapse of the posterior mitral leaflet and another had paradoxical movements of the interventricular septum. The study suggests that cardiac involvement is infrequent in PM-DM.

Soluble antigen fluorescent antibody test in the serodiagnosis of tuberculous meningitis.

Diagnosis of tuberculous meningitis (TBM) is difficult and frustrating. Modified soluble antigen fluorescent antibody (SAFA) test was applied to 40 CSF and 32 serum samples from 48 patients to assess the efficacy of this test in the rapid diagnosis of TBM. Using this test, false negative results were obtained in 41.6% and 40% of CSF and serum samples. False positive results were obtained in 22.2% and 26.7% of CSF and serum samples respectively. SAFA test was not found to be helpful in the sero-diagnosis of TBM. It is suggested that the best immunodiagnostic test for TBM will be to demonstrate the presence of antigen, antibody and antigen-antibody complex in the CSF for M. tuberculosis.

Contralateral hemiplegia in herpes zoster ophthalmicus. Role of temporal artery biopsy.

We describe clinical, radiological and pathological findings in a case of herpes zoster ophthalmicus who developed contralateral hemiplegia. The CT scan showed discrete infarction of the right internal capsule and the right carotid angiogram showed concentric narrowing of the supraclinoid portion of right internal carotid artery. Superficial temporal artery biopsy showed infiltration by lymphocytes and plasma cells without any granuloma formation or giant cells. The importance of trigemino-vascular connections in the pathogenesis of this complication of herpes zoster ophthalmicus and the role of temporal artery biopsy in the diagnosis of arteritis following herpes zoster are discussed.

Eating epilepsy.

The term "reflex epilepsy" denotes epilepsies characterized by a specific mode of seizure precipitation. Seventeen patients in whom the act of eating precipitated seizures are described. Interictal EEG showed generalized seizure discharges in three and focal discharges in five patients. In four patients EEG was recorded during eating. In one of these, the frequency of seizure discharge increased, but none had a clinical seizure during the recording. Eating epilepsy is predominantly a disorder of young adults, and the triggering mechanisms are extremely complex and elaborate. The role of the limbic system and amygdala in the precipitation of eating-induced seizures is discussed.

Appearance of tuberculoma during treatment of tuberculous meningitis.

Case histories of two young Indian female patients are described who, during the course of regular chemotherapy for tuberculous meningitis, developed tuberculoma as suggested by CT-scan. Such lesions were not seen at the start of treatment. Twelve similar cases are collected from literature. Most of the patients developed new symptoms and/or signs having initially shown good response to drugs. The pathogenetic mechanisms for such an evolution of lesions are not known but possibly include immunological modulations. This development should not lead to excessive anxiety for treating physician. Surgery is not needed and a patient follow up is well rewarded. Pyrazinamide has emerged as a useful drug.
