Significance of transplant perfusion index in the diagnosis of acute rejection in live related renal allograft recipients.

The study was undertaken to assess the usefulness of transplant perfusion index (TPI) in the differential diagnosis of renal allograft dysfunction with special reference to acute rejection. It was observed that the TPI has a sensitivity of 100 per cent and specificity of 98.1 per cent in the diagnosis of acute rejection. It was also observed that the serial values of TPI provided valuable clues and guide in the management of transplant dysfunction and helped in the immediate and long term follow-up of patients with renal allografts.

Malignant mesothelioma in the young (with prosthetic aortic valve an unusual association).

A case of malignant mesothelioma (MM) in a 15 year old boy is reported. He had a prosthetic aortic valve implanted in 1980 at our centre for rheumatic aortic regurgitation. Fever, weight loss and chest pain as initial symptoms suggested possibility of prosthetic valve endocarditis. Dysphagia as another initial symptom was interesting and caused further diagnostic dilemma. Role of Computerised Tomography (CT) scan in diagnosis of MM is highlighted.

Platelet count, platelet aggregation and fibrinogen levels following acute induction to high altitude (3200 and 3771 metres).

Two groups of 20 subjects each were separately exposed to altitudes of 3200 m and 3771 m for 10 days by rapid induction requiring 14 and 16 hours respectively to reach high altitude camps. A statistically significant fall in platelet counts was observed from day 2 at 3200 m and day 3 at 3771 m and counts remained decreased. Platelet aggregation was also decreased initially at both altitudes. Blood fibrinogen decreased only on day 2 at 3771 m with a significant increase over control values by day 10 at both altitudes.

Serum and urinary cation changes on acute induction to high altitude (3200 and 3771 metres).

Twenty subjects each were rapidly inducted by road to 3200 ad 3771 m. Serum and urinary sodium, potassium, calcium, and magnesium were measured during 10 d at high altitude. At 3200 m, only serum potassium increased significantly on the 10th day. At 3771 m, serum potassium did not increase. Serum sodium generally remained low, serum magnesium increased, while calcium decreased significantly. Urinary volume over 24 h decreased more and for longer duration at 3771 m than at 3200 m. Urinary cations did not change significantly at 3200 m. At 3771 m, sodium and potassium excretion decreased on days 1 and 3 later returned towards preinduction levels. Magnesium and calcium decreased throughout the high-altitude stay. Significant changes were noticed in serum and urinary cations on exposure to high altitude when adequate caloric intakes were not ensured.
