ABSTRACT
A study was undertaken in Mangalore, South Kanara District of Karnataka, India to evaluate the rising prevalence of coronary artery diseases in our country. Seventy hearts were analysed, at post-mortem, between December 1996 and December 1997. The coronary arteries and the myocardium were examined, both grossly and histologically, to relate them with regard to the age and gender of the deceased. Fifty five hearts were from males and 15 were from females. Forty eight (68.59%) hearts were proven to be afflicted with coronary atherosclerosis. Twenty seven of these had three or four vessel disease. A total of 192 sections from the four major epicardial arteries of the 48 hearts were examined. Of these, 124 showed atherosclerosis (with 37 in advanced stages), of which 103 were occlusive lesions while the remaining 21 were fatty streaks. Severe stenosis (grade III or IV) was commonest in the left anterior descending artery. Twenty one (30%) of the 70 hearts showed histological evidence of myocardial ischaemia. Of these 6 were from females and 15 were males. Myocardial ischaemia was found to have no correlation to the severity of stenosis.

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease of unknown etiology characterized by inflammation in various organ systems, including lymph nodes, due to the production of antinuclear antibodies. The onset of disease is between ages 13 and 40 years, with a female preponderance. CASE: A 30-year-old female presented with right cervical lymphadenopathy and gave a history of intermittent fever and swollen joints of 2.5 years' duration. The patient was on intermittent corticosteroids. With a suggestion of tuberculous lymphadenitis, the patient underwent fine needle aspiration (FNA). The diagnosis of lupus adenopathy was established by FNA of enlarged right cervical lymph nodes. Smears showed predominantly typical and atypical immunoblasts, plasma cells, occasional Reed-Sternberg-like cells and dispersed hematoxylin bodies. Smears were negative for acid-fast bacilli. CONCLUSION: When SLE patients develop lymphadenopathy, FNA cytology helps differentiate lupus adenopathy from infectious conditions, such as tuberculous adenitis, and from Kikuchi's lymphadenitis.

The junctional mucosa of 49 colorectal carcinomas were studied for Paneth cell metaplasia. Twenty two cases (44.89%) showed Paneth cells in the junctional mucosa. The carcinomas were seen mainly in the age range of 51 to 60 years (38.4%) The occurrence of Paneth cell metaplasia was higher in the vicinity of tumours of ascending colon and in well differentiated grades of adenocarcinomas. This probably indicates the reactive host response in the junctional mucosa which is of better prognostic significance.
