ABSTRACT
INTRODUCTION: Transfusion transmitted infections (TTIs) can cause threat to bloody safety as blood transfusion is an important mode of transmission of TTI to the recipient, hence, to prevent transmission of these diseases, screening tests on blood bags is an important step for blood safety. AIM: This study was undertaken with the aim of determining the seroprevalence of TTI in healthy blood donors in a tertiary care blood bank. MATERIALS AND METHODS: A retrospective study was carried out over a period of 5 years from January 2007 to December 2011. Serum samples were screened for hepatitis B surface antigen (HBsAg), antibodies to human immunodeficiency virus (HIV) Type 1 and 2, hepatitis c virus (HCV) and syphilis using enzyme-linked immunosorbent assays with the third generation kits and venereal disease research laboratory test, respectively. RESULTS: A total of 76,653 healthy donors were included out of which majority of donors were male (91.79%). The overall seroprevalence of HIV, HBsAg, HCV, and syphilis were 0.26%, 1.30%, 0.25%, and 0.28%, respectively. CONCLUSION: Methods to ensure a safety blood supply should be encouraged. For that, screening with a better selection of donors and use of sensitive screening tests including nucleic acid testing technology should be implemented.
ABSTRACT
Antiphospholipid antibody syndrome is a very important cause of cerebral infarction, myocardial infarction, and repeated pregnancy losses in women. We present an extremely rare case of a 44-year-old man with antiphospholipid syndrome who collapsed and died suddenly. At autopsy, he was found to have both cerebral and myocardial infarction. In all young patients with cerebral infarction, myocardial infarction, pulmonary embolism, recurrent miscarriages, and unexplained low platelet count, one must consider the strong possibility of antiphospholipid antibody syndrome.

BACKGROUND: Occult thyroid malignancies presenting with secondary neck masses as the first clinical manifestation is well known. Although rare, medullary carcinoma serves a potential source for lymph node metastases. The characteristic cytomorphology of medullary thyroid carcinoma (MTC) should clinch the diagnosis. Further, fine needle aspiration cytology (FNAC) of the ultrasonography-detected occult nodules in thyroid serves as a useful preoperative diagnostic tool. CASE: A 22-year-old man presented with left-sided neck masses of 1 year duration. FNAC smears of the neck masses revealed cytomorphology characteristic of MTC. Ultrasonography of the thyroid led to ruling out the presence of an occult nodule and detected an 8-mm nodule in the left thyroid lobe. Ultrasound-guided FNAC of the nodule showed features similar to those with FNAC of the neck masses. Surgical resection of thyroid and neck masses further confirmed the diagnosis of a primary occult MTC with lymph node metastases. CONCLUSION: FNAC smears of lymph node masses showing the distinct cytomorphology of MTC should prompt suspicion for occult primary in thyroid. Ultrasound-guided FNAC of these occult nodules, if detected, further serves a diagnostic tool for accurate preoperative diagnosis when metastasis presents as the first clinical manifestation of an occult primary.
