Stroke during pregnancy and puerperium in young females below the age of 40 years as a result of cerebral venous/venous sinus thrombosis.

One hundred and thirty-eight cases of cerebral venous/venous sinus thrombosis during the puerperium have been studied. Maximum number of cases (112 cases) occurred in the age below 30 years. Signs and symptoms appeared in most of the cases (72 cases) during the first 7 days of post partum period. One hundred and eleven cases were multipara. Commonest signs and symptoms were fever (85 cases); headache (66 cases), convulsions (64 cases), altered consciousness (57 cases), hemiplegia (60 cases), papilloedema (48 cases), etc. Carotid angiography done in 55 cases revealed block in middle part of superior sagittal sinus in 24, and localised, dilated and tortuous cortical veins in 5. A statistically significant rise in serum triglycerides, phospholipids, free fatty acids, blood platelet count, platelet adhesive index, and fall in blood fibrinolytic activity were found as compared with normals. These factors may be playing a role in the etiology of cerebral venous/venous sinus thrombosis during puerperium.

Effect of chronic severe anemia on left ventricular performance. A study of systolic time intervals.

Results of measurements of systolic time intervals (STI) in 32 patients of chronic severe anemia, before and after treatment, were studied. The patients were all without any clinical, radiological, or electrocardiographic evidence of cardiac decompensation. Data from an equal number of normal age and sex matched control subjects were also analysed. STI in individual patients showed a wide variation which precluded specific diagnostic utility. As a group, however, anemic patients showed significant differences from normal control subjects. Significant differences between pre-treatment and post-treatment values also suggest that chronic severe anemia adversely affects cardiac contractile function. Of the various STI measurements, PEP and PEP/LVET ratio were found useful parameters to be studied.

Serum lipids and uric acid relationship in ischemic thrombotic cerebrovascular disease.

Serum lipids and serum uric acid have been studied in 50 patients with ischemic thrombotic cerebrovascular disease. Patients having diseases known to predispose to hyperuricemia were excluded. Abnormalities of large vessels were present in 14 or 30 cases (46.6%) as a whole, and in 9 of 16 cases (56.5%) below 40 years of age. Thirty percent of the cases showed hyperuricemia. A statistically significant rise in serum triglycerides, pre-beta lipoproteins and serum uric acid was found in all 50 patients and in patients below 40 years of age. In patients above 40 years of age, only the rise in serum triglycerides and pre-beta lipoproteins was found to be statistically significant. A statistically significant rise in serum triglycerides, pre-beta lipoproteins, cholesterols and uric acid was found in patients with abnormal angiograms. A statistically significant correlation was observed between serum uric acid and serum triglycerides in all the groups, between serum uric acid and pre-beta lipoprotein in patients below 40 years of age, and between serum uric acid and serum phospholipids in patients with abnormal angiograms. These factors may be playing a role in the causation of ischemic thrombotic cerebrovascular disease in general and especially in patients below 40 years of age.

Role of H-reflex latency studies in the diagnosis of subclinical diabetic neuropathy.

Motor conduction velocity (MCV) in the median, ulnar and peroneal nerves and H-reflex studies have been conducted in 50 diabetics aged 20-65 years and 25 controls. MCV in the upper limb was below the normal range in 16% of diabetics. 28% diabetics showed abnormal MCV in the peroneal nerve. H-reflex abnormality consisting of either prolonged latency or its complete absence could be observed in 54% of diabetics. The results indicate the greater sensitivity of H-reflex in the detection of sub-clinical diabetic neuropathy. Greater prevalence of neuropathy in the early onset diabetes than in the late onset type is also suggested.
