Efficacy of Pooled Serum Internal Quality Control in Comparison with Commercial Internal Quality Control in Clinical Biochemistry Laboratory.

 With increasing automation in clinical laboratories, the requirements for quality control (QC) material have greatly increased in order to monitor performance. The constant use of commercial control material is not economically feasible for many countries because of nonavailability or the high-cost of those materials. Therefore, preparation and use of in-house QC serum will be a very cost-effective measure with respect to laboratory needs.

Association of Serum Magnesium with Oxidative Stress in the Pathogenesis of Diabetic Cataract.

Magnesium deficiency enhances oxidative stress which contributes to early development of cataract formation, and also the progression in type 2 diabetes mellitus patients remains unclear. The present study was designed to evaluate the serum levels of magnesium, oxidative stress marker and antioxidant status and to find out if there is any association between them in the pathogenesis of diabetic cataract compared with non-diabetic senile cataract, diabetes without cataract and normal healthy subjects. This comparative study includes 90 type 2 diabetes mellitus patients with cataract, 90 non-diabetic senile cataract patients, 90 type 2 diabetes mellitus without cataract and 90 normal healthy individual subjects without cataract in the age group between 40 and 75 years of both genders.

Prevalence of dry eye disease and its association with dyslipidemia.

Background: Dry eye disease (DED) is a common ocular surface disease significantly affecting the quality of life of patients. The aim of our study is to focus on the prevalence of DED and to determine the relationship between dyslipidemia and DED.

Methods: The study was performed with the age group of 25-70 years, who attended the ophthalmology outpatient department at Sri Lakshmi Narayana Institute of Medical Sciences with complaints of dry eye.

Relationship between Lipoprotein(a) and Thyroid Hormones in Hypothyroid Patients.

Background And Objective: Changes in plasma lipid concentrations are well known metabolic consequences of thyroid dysfunction. The alterations are most prominent in hypothyroidism which is typically associated with pronounced hypercholesterolaemia and frequently with moderate hypertriglyceridaemia. In cases of hypothyroidism, how the serum Lp(a) levels are influenced by thyroid hormone remains unknown and contradictory results on the effect of thyroid hormone on serum Lp(a) levels have been reported.
