Oxidative stress in diabetic patients with retinopathy.

Background: Diabetes mellitus (DM) is known to induce oxidative stress along with deranging various metabolisms; one of the late complications of diabetes mellitus is diabetic retinopathy, which is a leading cause of acquired blindness. Poor glycemic control and oxidative stress have been attributed to the development of complications like diabetic retinopathy. The aim of this study was to analyze and correlate oxidative stress marker, Malondialdehyde (MDA), and antioxidants (erythrocyte glutathione, vitamin C) along with glycosylated hemoglobin (HbA1c) and fasting blood sugar (FBS) in diabetic patients with and without retinopathy.

Computed tomogram guided fine-needle aspiration cytology of lung mass with histological correlation: A study in Eastern India.

Background: Fine-needle aspiration cytology (FNAC) is an important and useful investigation, and is considered next to imaging in the rapid diagnosis of pulmonary mass lesion for the last few decades.

Aims: To assess the role of Computed Tomogram (CT) guided FNAC in pulmonary mass lesions; to analyze the results; and to compare with histopathological findings.

Materials And Methods: The clinical, radiological, and cytological data of 130 patients were prospectively studied who underwent CT guided FNAC from October 2009 through September 2011.

Serum magnesium levels in patients with diabetic retinopathy.

Background: Diabetic retinopathy is one of the leading causes of blindness in the world. Hypomagnesemia has been reported to occur at an increased frequency among patients with type 2 diabetes compared with their counterparts without diabetes. Hypomagnesemia has been linked to poor glycemic control.

Objective structured practical examination in biochemistry: An experience in Medical College, Kolkata.

Background: Undergraduate medical examination is undergoing extensive re evaluation with new core educational objectives being defined. Consequently, new exam systems have also been designed to test the objectives. Objective structured practical examination (OSPE) is one of them.
