It has additionally been established that the thyroid contains more selenium than any other tissue and that selenium deficiency aggravates the manifestation of endemic myxedematous cretinism and autoimmune thyroid disease. Evidence Acquisition: Clinical reports as well as a large number of biochemical articles linking selenium to thyroid have been considered. Interventional, prospective, randomized, controlled studies, including large observational studies, supplementing selenium in autoimmune thyroid disease, together with review articles published in Medline and Pubmed have undergone scrutiny. The methodological differences and variety of results emerging from these trials have been analyzed. Evidence Synthesis: Evidence in support of selenium supplementation in thyroid autoimmune disease is evaluated, the results herein presented demonstrating the potential effectiveness of selenium in reducing the antithyroid peroxidase titer and improving the echostructure in the ultrasound examination. However, considerable discord remains as to who should comprise target groups for selenium treatment, who will most benefit from such treatment, the precise impact of the basal antithyroid peroxidase level, and the effect of disease duration on the treatment outcome. Clearly, further in-depth studies and evaluation are required concerning the mechanism of action of selenium as well as the choice of supplements or dietary intake. Conclusions: Maintenance of "selenostasis" via optimal intake not only aids preservation of general health but also contributes substantially to the prevention of thyroid disease.

Study Design: Cross-sectional cohort study. Place and Duration of Study: This study was conducted in the Department of Endocrinology, Gauhati Medical College and Hospital, Assam, India between December 2016 to March 2018. Methodology: We included 100 patients (60 males and 40 females; age range: 36–72 years) with type 2 DM. Their clinical, biochemical, and metabolic parameters were analyzed and assessment of CAN were done based on the Ewing's criteria. Results: Out of 100 patients, 60 were males and 40 were females. The mean age of the patients was 53.3 ± 10.37 years (36–72 years) and the mean duration of diabetes was 9.03 ± 6.4 years (6 months–25 years). Patients were divided into two groups: “without CAN” (CAN−) and “with CAN” (CAN+). The prevalence of CAN was 70%, with early CAN in 25%, definite CAN in 24%, and severe CAN in 21% cases The p...

The clinical significance of a lack of regular menstrual cycles extends beyond reproductive concerns. Episodes of amenorrhea as short as 90 day may have implications for bone and cardiovascular health. To evaluate all patients presenting with primary amenorrhea in the Endocrinology OPD of Gauhati Medical College and Hospital. A total of 14 patients presenting to the Endocrinology OPD from March 2010 to May 2012 with a history of primary amenorrhea were included in the study. All patients were subjected to a detailed history, a thorough clinical examination, and relevant biochemical, hormonal, and radiological investigations. In our study, the average age of presentation was 17.23 ± 4.2 years. Out of the 14 patients presenting with primary amenorrhea, 5 patients (35.71%) were found to have Turner's syndrome, 2 (14.28%) had XX (pure) gonadal dysgenesis, 2 (14.28%) pat...
