Morphological study of liver in patients of chronic hepatitis C treated with interferon.

The effect of interferon therapy on liver morphology was assessed in ten patients with serologically proven chronic hepatitis C. All these patients received 3 million units of alpha interferon three times a week. Six patients received therapy for 6 months, two patients for 12 months, one patient each for 3 and 9 months. All patients underwent a second liver biopsy 1 to 6 months after cessation of therapy. Alanine aminotransferase levels were determined before, during and after therapy. Each biopsy was assessed histologically by revised classification of chronic hepatitis proposed by Desmet et al and Kondell histological activity index was determined. Four patients showed significant reduction in the necroinflammatory activity with decrease in the HAI and normalisation of ALT level. Three patients showed partial reduction in the necroinflammatory activity with partial reduction of ALT levels. Two patients did not show any change in the grade of disease while one patient showed worsening of necroinflammatory activity with rising ALT levels. One patient showed a significant reduction in fibrosis with conversion of early developing cirrhosis into bridging fibrosis. A second liver biopsy is extremely useful for assessing the response of interferon treatment, however, it must be done at a suitable time after cessation of therapy.

The morphological variants of papillary carcinoma of the thyroid: a clinico-pathological study--AFIP experience. Armed Forces Institute of Pathology.

Many variants of papillary carcinoma of thyroid have been described. Identification of some of these may have prognostic implications. Eighty-two cases of papillary carcinoma of the thyroid diagnosed at Armed Forces Institute of Pathology, Rawalpindi over a six year period were reviewed with the aim of identifying these variants. Fifty-eight (70.7%) were classical papillary carcinoma. Thirteen (15.9%) had follicular variant, 6 (7.3%) columnar cell variant and 3 (3.7%) had tall cell variant. The mean age at diagnosis was 27 years for classical papillary carcinoma, 46 years for follicular variant, 61 years for columnar cell variant and 52 years for tall cell variant. The columnar cell variant had a more aggressive clinical presentation than others. Tall cell, columnar cell and diffuse sclerosing variant have a poor prognosis. An effort should be made to identify them on histopathology so that specific therapy can be planned.

A morphological study of histological activity index (HAI) and scoring system in hepatitis-C.

A retrospective morphological study of 25 cases of serologically positive chronic hepatitis C was carried out. Paraffin embedded sections were stained with haematoxylin, eosin and Gomori reticulin stains. The histological features were scored according to both Knodell and Scheuer systems. The results of Knodell showed 32% cases scored between 4-8 and 48% between 9-12. Cases of conventional category of chronic persistent hepatitis scored between 1-3 and chronic active hepatitis score ranged between 4-12. The scoring systems provide a good guideline for management/selection of cases for interferone therapy and subsequent evaluation and assessment of the cases.

The use of fine needle aspiration biopsy in the management of thyroid disease.

Fine needle aspiration biopsy is now a first line investigation in thyroid disease. The purpose of this study was to evaluate the results of this technique in comparison with routine histopathology. A total of 593 aspirations over a four year period were included. There were 390 (65.7%) solitary nodules, 124 (20.9%) multinodular goiters, 66 (11.1%) diffuse goitres and 13 (2.2%) recurrent post thyroidectomy nodules. Radioisotope scanning in 386 cases showed 325 (84.2%) cold nodules, 54 (14.0%) warm nodules and 7 (1.8%) hot nodules. There were 458 (77.2%) colloid goitres and cysts, 14 cases of thyroiditis (2.2%) and 30 malignancies diagnosed on fine needle aspiration biopsy. In 19 cases (3.2%) a diagnosis of follicular neoplasm and in 29 cases (4.9%) a diagnosis of suspicious aspirate was made. Histological results were available in 176 cases. In 108 cases findings of histology and FNAB were compared with radioisotope scanning. A sensitivity of 92.8% and 42.8%, a specificity of 90.1% and 98.7% and accuracy index of 90.3% and 94.3% was found, when considering suspicious cases alternatively as positives and negatives. Surgery was recommended in all suspicious cases to prevent reduction in sensitivity of the technique. Fine needle aspiration biopsy was found to be a highly effective procedure which can obviate a lot of unnecessary surgery in thyroid lesions.

Plasma cell granuloma: maxillary sinuses.

Inflammatory pseudotumours or plasma cell granulomas are space-occupying, rounded masses appearing in various locations usually as an aftermath of recurrent infections. Recurrent pain and mass have been the most common presentations (Durst et al., 1977). These have been confused with tumours but radical surgical treatment is unnecessary, in the absence of life-threatening complications. The prognosis is excellent after excision. The nature and pathogenesis of the inflammatory pseudotumours, their presentation as fever and anaemia in some cases, are unknown. This report is probably the first case of a plasma cell granuloma involving the maxillary sinus causing focal erosion of the orbital wall, simulating a malignant tumour clinically.

Effect of different dietary brans on lipid metabolism in male albino rats.

Male albino rats were fed different dietary brans at 20% level for two months to study their effect on lipid metabolism. Wheat and corn brans significantly (P less than 0.05) decreased the serum cholesterol level while chickpea bran significantly (P less than 0.05) lowered the liver and heart cholesterol concentrations. Significant (P less than 0.05) reduction was observed in liver and heart triglyceride with all brans. Wheat, corn and chickpea brans fed at 20% level had no significant effect on serum triglyceride concentration.
