ABSTRACT
A young lady developed left middle cerebral artery embolism after percutaneous transseptal mitral commissurotomy. She was successfully treated with immediate percutaneous transluminal angioplasty. There was complete recovery of neurological deficit.

OBJECTIVE: To determine the short term results and safety of angioplasty in chronic coronary occlusions. METHODS: Eighty consecutive patients undergoing percutaneous transluminal coronary angioplasty (PTCA) for chronic coronary occlusions were prospectively analyzed for acute success rate and safety of the procedure. RESULTS: The mean age was 46.7 years (range 30-78 years). There were 72 males and eight females. Clinical presentation was recent myocardial infarction (MI) in four cases (5%), unstable angina in 20 (25%), chronic stable angina in 24 (30%) and past history of MI in 32 (40%) cases. Vessel distribution was left anterior descending artery (LAD) in 40 (50%), left circumflex artery (LCx) in 12 (15%) and right coronary artery (RCA) in 28 (35%) cases. Lesion length varied from 8 mm to 37 mm with a mean of 16.7 mm. Acute success rate was 70% (56/80). Twenty four cases (30%) had unsuccessful result due to failure to cross with wire (18 cases) or inability to cross with the balloon (six cases). One major complication in the form of type III coronary perforation was encountered which was successfully managed surgically. CONCLUSION: Percutaneous transluminal coronary angioplasty (PTCA) in chronic total occlusion has a reasonable success rate and very low complication rate.

During the last 6 years, 7 healthy individuals who were reasonably well acclimatised to physical exertion came under observation with acute renal failure due to exercise induced myoglobinuria. Their mean age was 20 years, and renal failure resulted after cross country run of 10-15 km in 6 cases and long route march of 90 km in 3 days in one case. There was no evidence of effects of heat, dehydration or hypotension. Apart from myoglobinuria and significant urinary sediments, serum aldolase (mean 69.0 SL u/ml) and serum creatinine phosphokinase (mean 120.0 Sigma u/ml) were also elevated. Maximum blood urea and creatinine were 224 mg/dl and 13.9 mg/dl respectively. Hypocalcaemia was noticed in 3 cases, hyperkalaemia in 4 cases and hyperuricaemia in one case during the oliguric phase. One case had features of non-oliguric acute renal failure. All cases recovered though 4 cases required dialysis support. Kidney biopsy in 3 cases showed recovering acute tubular necrosis with eosinophilic material in tubules. Lactate studies in the convalescent period revealed normal response and repeat physical exertion of same severity after 6 months did not reproduce the syndrome. It is concluded that exertional rhabdomyolysis unassociated with heat stress is a rare entity, and with prompt diagnosis and energic management results are rewarding.

A patient who developed hypopituitarism after viperine envenomation is described. Thrombosis as a part of disseminated intravascular coagulation may have been the cause. Hypopituitarism should be suspected in such cases especially when there is associated acute renal failure.
