RESUMO
Background: The Thyroid hormones normal levels are very much essential for fetal neural development and good pregnancy outcome. Thyroid insufficiency during pregnancy may be associated with adverse obstetric outcome and fetal neurodevelopmental deficits. The main objective of the study is to estimate and establish the reference ranges of thyroid hormones as it varies from place to place and inter dependent on the iodine levels as the American Thyroid Association strongly recommends to refer to population defined trimester-specific reference ranges.Methods: A longitudinal study was conducted at obstetric clinic, Kakinada city, Andhra Pradesh over a period of 18 months. The total number of normal pregnancy subjects included in this study was 126. Thyroid hormones estimation was done by Competitive electrochemiluminescence (T3 and T4) and Sandwich electrochemiluminescence (TSH) at Thyorocare Laboratory. Only 47 subjects were having all three trimester thyroid hormone levels estimated during each trimester and were followed up to full term. The 2.5th and 97.5th percentiles were calculated as the reference intervals for thyroid hormone levels during each trimester.Results: The thyroid hormone levels during first, second and third trimesters median with reference intervals - Total Triiodothyronine (T3) : 163(100.2-230), 168(121-219.2), 168(110.2-222.6) ng/dl ,Total Thyroxine (T4) : 8.4(4.05-16.64) , 10.2(4.09-18.7), 11.2(3.8-16.7) μg/dl and Thyroid Stimulating Hormone (TSH ):2.52(1.6-7.9) 3.01(1.28-7.6) 3(1.5-8.4) μIU/mlConclusions: The trimester-specific reference intervals and median for thyroid hormones during normal pregnancy have been established for pregnant South Indian women in Andhra Pradesh by full term follow-up during pregnancy using 2.5th and 97.5th percentiles and median.
RESUMO
Background: Diseases of the heart valves constitute a major cause of cardiovascular morbidity and mortality worldwide with an enormous burden on healthcare resources. The present study was undertaken to study incidence and demography of valvular heart disease, to assess echocardiography and colour doppler findings of patients with valvular heart disease and to find out complications in patients with valvular heart disease.Methods: A hospital based longitudinal case study was undertaken at medicine department of Dr. V.M. Government Medical College, Solapur, Maharashtra, India for a period of two years. One hundred and twenty-four (124) patients attending OPD participated in the study.Results: In the present study, out of 124 patients, mitral valve was most commonly involved, 105(84.67%) and the least common involved was tricuspid 1(0.81%). The most common aetiology was rheumatic origin 75(94.94%). In the present study the most common complication was pulmonary hypertension 69(55.65%), followed by congestive cardiac failure (33.87%), acute pulmonary edema (12.09%), infective endocarditis (4.84%), cerebrovascular accident (4.03%), left atrial thrombus (3.23%) and death (3.23%).Conclusions: Multiple valves were affected in more than a third of all cases, although recent research in India continue to demonstrate a declining trend in the prevalence of RHD, rheumatic involvement is still the dominant form of valvular heart disease in India.
