    Human sodium iodide symporter (hNIS), responsible for the active transport of iodine is an integral plasma membrane glycoprotein present in the thyroid cells and extrathyroid tissues like breast and salivary glands. If its functional form is unequivocally shown in benign or malignant breast tissues, then it may serve as a basis for diagnosis and treatment using radioactive iodine. With an aim to analyze the hNIS expression in a distinct benign breast condition of fibroadenoma, biopsy proven fibroadenoma tissues, normal non-lactating breast tissue and biopsy proven infiltrating duct carcinoma tissues were examined for hNIS expression using immunohistochemistry. Out of 20 biopsy proven fibroadenoma tissues, 19 (95%) showed positivity for hNIS protein and only one was negative. Of these 10% were mildly positive, 50% cases were moderately positive and 35% showed intense positivity. None of the control tissue obtained from reduction mammoplasty specimens or normal breast tissues samples (5 cms away from the tumor) were positive. hNIS was also intensely positive  in 9 out of 10 (90%) infiltrating duct carcinoma tissues and moderately positive in one case. These preliminary results show that hNIS was present in high frequency as demonstrated by immunohistochemistry in fibroadenoma breast.

    Background:To study the prescription behavior of oral contraceptive pills (OCPs) by physicians, gynecologists, and alternative medicine practitioners (AMPs). Materials and Methods?Close-ended questionnaire-based cross-section study was performed between 1st September 2012 and 28th February 2014 in three groups of responders, i.e., AMP, general medical practitioners (GMPs), and obstetricians and gynecologists (ObGy). A stratified random cluster sample was used. Data of 400 subjects in all three groups were obtained using both univariate and multi-variate sophisticated statistical analyses for analyzing attitude and practices and were recorded on an ordinal scale using appropriate non-parametric test. Results?Of the 1,237 subjects surveyed, 400 completed questionnaires were received from each of the three groups viz; AMPs, GMPs, and ObGy. Remaining 37 incomplete questionnaires were not included in the final analysis. Conclusion?There are equal misconceptions regarding OCPs among users and prescribing physicians. Preference for OCPs in married and unmarried women is also equally low. OCP usage and their prescription practices can be improved by removing potential barriers, developing public–private partnership, and training promoters.
