Fructosamine: an alternative assessment of past glycaemic control in developing countries

Fructosamine assay determines glycaemic control in diabetic patients by measuring glycosylated plasma protein. This study was done to assess the value of fructosamine as an alternative test to HbA1c as a measure of glycaemia. Sixty patients (both insulin dependent diabetes mellitus and non insulin dependent diabetes mellitus) were selected from the diabetic clinic and fasting blood samples were collected for estimation of glucose, HbA1c and fructosamine levels. The results were compared by correlation analysis and major discrepancies/discordance was detected by dividing the results into 3 clinical categories and detecting the cases in which the values fell in opposite clinical categories. Fructosamine correlated well with HbA1c (r = 0.41, p \u3c 0.01) and with fasting blood glucose (r = 0.45 p \u3c 0.01). Major discordance was detected in the results of only 7 patients which can partly be attributed to different periods over which HbA1c and fructosamine reflect average glycaemia. Fructosamine measures glycaemia over the past 2-3 weeks and HbA1c over 8 weeks. As fructosamine assay is relatively inexpensive, reliable and simple to perform; it can be used as an alternative to HbA1c and is particularly suited for developing countries

CSF oligoclonal bands in multiple sclerosis

Objective: To study the significance of oligoclonal bands in neurological disorders, specifically in Multiple Sclerosis (MS). Methods: The study was designed to assess the sensitivity and specificity of the test methodology of CSF electrophoresis by performing the retrospective analysis of CSF samples sent for oligoclonal bands (OCB). A total of 603 samples were received by the Clinical Laboratories, Department of Pathology of The Aga Khan University, during a period of 54 months (January 1993-June 1997). All of these samples were analyzed by performing CSF protein electrophoresis. One hundred thirty three out of 603 samples showed evidence of OCB. Out of these, 24 patients were registered with Section of Neurology, Department of Medicine, The Aga Khan University Hospital. These 24 patients were finally selected for analysis. Relevant clinical details such as age, sex and clinical presentations were recorded. Results: Fifteen (62%) out of 24 patients with positive OCB were diagnosed as cases of MS. Four (17%) patients were diagnosed to have subacute sclerosing panencephalitis (SSPE). Five (21%) patients were having other inflammatory neurological disorders. Conclusion: The overall relative sensitivity and specificity for multiple sclerosis were found to be 100% and 62.5% respectively. Lack of specificity was attributed to the fact that OCB were positive in other neurological disorders as well

Breast diseases in males--a morphological review of 150 cases

Objective: This study was carried out to observe the prevalence breast diseases of males in our setup. Method: All cases of male breast disease diagnosed from 1991-97. Results: One hundred and fifty (150) cases of male breast diseases were diagnosed. Age of the patients ranged from 4 to 90 years, with mean age 38.75 years (median = 33 years). Gynecomastia was the most common pathological abnormality of the male breast (58.66%). Most of the patients presented in the 3rd decade of life. Amongst the malignant conditions, infiltrating ductal carcinoma was most prevalent (82%). Most of the patients with malignancy presented in the 5th and 6th decades of life. Conclusion: Gynecomastia was the most prevalent male breast disorder, followed by infiltrating ductal carcinoma. Our findings correspond with that of world literature

Clinical, pathological and molecular factors predicting Axillary Node involvement in primary Breast Cancer in Pakistani women

Background: Axillary lymph node involvement in primary breast cancer is one of its most important prognostic features. Thus any factors that may predict axillary lymph node involvement in this setting could be potentially helpful in treatment planning and other interventions. Objective: The objective of this study was to evaluate clinical, pathological and immuno-histochemical markers in univariate and multivariate analysis, which may be helpful predictors of axillary lymph node involvement in breast cancer. Method: A retrospective analysis of 555 cases. Of these 58% had axillary nodal positivity and 42% were negative. Conclusion: Factors of no significance included patient’s age, height, weight, age of first pregnancy, parity, marital status, menopausal status, family history of breast cancer, side of tumor. In univariate analysis the age of menarche, duration of symptoms, tumor size, site in outer quadrant, S phase and skin and nipple involvement all predicted axillary nodal involvement. The length of breast-feeding, increased intraductal component and increased PCNA were inversely proportional to nodal involvement. In multiple regression analysis however only size of the tumor, involvement of the skin and nipple and disease in the outer quadrant of breast were the factors, which assumed significanc

Diagnostic Surgical Pathology: the importance of Second Opinion in a Developing Country

Objective: To review the cases sent to the section of histopathology, Aga Khan Universty (AKU) for second opinion and see whether there are significant differences in the original outside diagnosis and the subsequent diagnosis submitted by us. Methods: A retrospective study of all consecutive cases for second opinion in the form of paraffin blocks from 1st Novemver 2001 to 31st July 2002. The primary submitted diagnosis in each case was compared with the subsequent AKU diagnosis. Results: The study included a total of 381 cases. However, in 45 cases (11.81%), initial histopathological diagnosis was not provided. Out of the remaining 336 cases, there were differences between the original diagnosis and the subsequent AKU diagnosis in 120 cases (35.71%). Out of these 120 cases, immunohistochemistry was performed in 65 cases (54.16%) only. Conclusion: In a developing country like Pakistan, where few laboratories are equipped to function as modern histopathology units, second opinion on difficult cases is very important. Worldwide, the concept of second opinion in surgical pathology is well established
