Sarcoidosis in India.

Sarcoidosis in India frequently presents in elderly males with a dissociation between extensive radiological changes and scanty clinical signs in the chest. Clubbing is not infrequent. Erythema nodosum, generalized lymphadenopathy, eye changes, and bone cysts are uncommon. Spontaneous resolution or asymptomatic course is very rare. Follow-up reports, whenever available, show that patients have frequent relapses which respond well to short courses of steroids. This comparative study shows a few differences between this series (of 90 cases diagnosed from 1957 to 1982), two different Western series and the World series. Detection and documentation of cases of sarcoidosis in India have been on the increase during the last few decades. Whether that is due to increase in incidence or awareness is difficult to say. In two special centres in India, the frequency of detection of the disorder varied between 61.2 (in a chest hospital in Delhi during 1957-74) to over 150 per 100 000 patients (Calcutta) attending a general hospital with a sarcoidosis clinic (1980-82).

Stent graft in managing juxta-renal aortoiliac occlusion.

Endovascular procedures are frequently used as an alternative to surgical bypass in aortic and iliac occlusion. Stents have revolutionized the scope of such endovascular procedures, but there are few reports of stents or stent grafts in occlusive juxta-renal aortic occlusion. We present a case where such occlusion was managed by use of a stent graft with successful outcome.

Serum angiotensin converting enzyme in respiratory diseases.

More than 1700 estimations of serum angiotensin converting enzyme (SACE) were undertaken, mostly in respiratory disorders, to assess its value as a specific and/or a sensitive indicator of different diseases. Though highest levels were found in lepromatous leprosy consistently, it was also found almost always elevated in active stages of sarcoidosis. Since it is raised in a variety of respiratory disorders, it is not a specific diagnostic test. It is, however, a fairly sensitive index of disease activity in sarcoidosis whether on treatment or not. Sudden elevation, after a prolonged period of low or normal values may indicate relapse in sarcoidosis.

Utilisation pattern of blood in a teaching hospital of Kolkata.

An annual utilisation of blood transfusion services at several depts. of R.G. Kar Medical College and Hospital, Kolkata were assessed among a sample of 3122 patients selected by Systematic Random Sampling Technique from the register made available in the blood bank there. Record analysis revealed that overall 79.4% of supplied blood units were actually transfused, wastage of 21.6%. Wastage was maximum in the Department of Gynae & Obstetrics (33.11%) and Surgery (32.87%). Only single unit of blood was requisitioned and transfused for 5.44% & 30.90% of the patients respectively. Most common indications of blood transfusion were for surgical cases (37.92%), followed by anaemia (34.80%) and haemorrhage (26.92%). The use of blood and blood products merit attention, appraisal and instructional guiding accordingly.

Follow-up results of balloon angioplasty for native coarctation of aorta.

Balloon angioplasty of native discrete (< 1 cm) coarctation of thoracic aorta was performed in 29 patients [aged 13 to 31 years (mean 21.5 +/- 5.8 years), 22 males and 7 females], from March 1993 to December 1995. The patients were followed up for two years. After angioplasty, peak systolic arterial pressure (PSAP) decreased from 173.5 +/- 18.1 mm Hg to 122.5 +/- 9.9 mm Hg (p < 0.001), peak systolic pressure gradient (PSG) decreased by 90.9 percent from 86.2 +/- 15.77 to 7.77 +/- 3.8 mm Hg (p < 0.001) and the coarcted segment diameter increased about three times from 3.7 +/- 1.6 to 10.9 +/- 3.3 mm (p < 0.001). PSG decreased to < 10 mm Hg in 27 patients (93%) whereas in the other two patients PSG was 17 and 13 mm Hg. Restenosis appeared in 2 patients (6.8%); aneurysm in one patient (3.4%) which remained static even after 1.3 years of follow-up; mild dissection in 3 patients (10.3%); temporary femoral artery occlusion in 2 (6.8%) patients who recovered with heparin injection. Though hypertension disappeared after balloon dilatation in all patients, it reappeared in 3 patients (10.3%) within 7 days and in 10 patients (34.5%) within 6 months. In conclusion, balloon angioplasty of CoA is a good alternative to surgical correction.
