ABSTRACT
Thyroid functions affect metabolic syndrome (MetS) parameters including blood pressure, fasting plasma glucose, serum triglycerides and HDL-Cholesterol. But the relationship between MetS and thyroid functions is yet to be identified clearly. Metabolic syndrome is a state in which most features of hypothyroidism can be seen. The aim of the present study was to investigate the frequency of MetS in hypothyroid patients. Thirty one patients with overt hypothyroidism, 32 patients with subclinical hypothyroidism (SCH) and 58 euthyroid controls were enrolled in this study. NCEP-ATP III criteria was used to diagnose metabolic syndrome. Majority of the participants were in the age group of 30-40 years. Body mass index and waist circumference, blood pressure, fasting plasma glucose and serum triglycerides were found to be higher in hypothyroid patients compared to that of euthyroid controls (p<0.001). On the other hand serum HDL-C was found to be significantly lower in hypothyroid patients compared to that of euthyroid controls (p<0.001). Prevalence of MetS was 82.5% in the hypothyroid group and 27.6% in eythyroid controls (p<0.001). No significant difference was found between SCH (81.3%) and overt hypothyroid (86.7%) groups in respect to prevalence of MetS (p<0.05). The findings of the study suggest a need to investigate the presence of hypothyroidism during the management of MetS patients.
ABSTRACT
Type 2 diabetes is considered as a major health burden due to its rising prevalence and disabling, life threatening complications. Dyslipidemia, often coexisting with T2DM as a feature of insulin resistance, is hypothesized to be linked with altered magnesium homeostasis. This study was designed to evaluate the serum magnesium levels and its influence on serum lipids in type 2 diabetics. Lipid profile, serum magnesium (Mg) and fasting serum glucose (FSG) were measured in 30 newly diagnosed normotensive type 2 diabetic patients chosen as cases (Group II) just before introducing any treatment, and was compared with that of 30 healthy controls (Group I). The serum magnesium was found to be significantly lower (p<0.001) and LDL-c was found to be significantly higher (p<0.01) in cases. The correlation analysis revealed a significant negative association of FSG to serum magnesium (r= -0.720), total cholesterol (r=-0.483) and a positive correlation to HDL-c (r=-0.440). However, serum magnesium showed a significant positive relation only with serum HDL-c (r =0.372, p<0.05). Serum magnesium and lipid fractions showed wide range of variation within the normal reference ranges in the newly diagnosed T2D subjects. Further large scale studies are needed to elucidate the association of serum magnesium with lipid profile changes. Estimation of serum magnesium level may prove useful in T2DM with normal or abnormal lipid levels or in those who are prone to develop dyslipidemia or certain complications associated with dyslipidemia.

ABSTRACT
Background: Hypothyroidism is an important public health problem in Bangladesh. It is associated with increased risk for atherosclerosis and other complications. The frank development of hypothyroidism is associated with metabolic derangements including dyslipidemia- which is an etiopathologic factor for development of renal impairment. This study was to evaluate whether hypothyroidism is associated with impaired renal function. Methods: Using a cross sectional analytical study design, a total of 111 subjects attending Out Patient Department, Center for Nuclear Medicine and Ultrasound, Bogra Medical College during January 2007 to December 2007 were included purposively. Eighty newly diagnosed hypothyroid patients (Group I) and 31 healthy adults (Group II) were enrolled in this study. Serum thyroid stimulating hormone and serum free thyroxine were assayed by radioimmunoassay. Serum fasting lipid profile, serum creatinine and serum uric acid were estimated by enzymatic colorimetric method. Estimated GFR was calculated using MDRD equation. Results: The mean (±SD) age of in Group I and Group II were 35.59 (±6.91) and 37.35 (±2.78) years and were comparable. In Group I, there were 66 females and 14 males. In Group II, there were 16 females and 15 males. The mean BMI was 25.49 ±2.17 kg/m2 in Group I and 24.24 ±1.99 kg/m2 in Group II. The mean (±SD) Serum total-cholesterol, LDL- cholesterol and tryacylglycerol in Group I were significantly higher than that in Group II. Serum HDL cholesterol in Group I was significantly lower than that in Group II (p<0.001). The mean (±SD) serum creatinine was significantly higher in Group I than Group II (P<0.001). The estimated glomerular filtration rate (eGFR) was lower in Group I compared to Group II (p=0.011). In Group I (Hypothyroid), there were significant correlations of BMI, S Total-Cholesterol, S HDLCholesterol, S LDL-Cholesterol, S triglycerides and S creatinine with serum TSH level. In Group I (Hypothyroid), there were significant positive correlations of BMI and TSH with serum creatinine. Conclusions: Hypothyroidism is associated with dyslipidemia, hyperuricemia and impaired renal function. Therefore, patients presenting with these biochemical abnormalities are recommended to be investigated for hypothyroidism and vice versa.
ABSTRACT
Inflammation has been shown to play a role in atherosclerosis and acute coronary syndrome. This study was carried out to evaluate the relationship between baseline white blood cell (WBC) count and C-reactive protein (CRP) with angiographic severity of coronary artery disease in patients with acute coronary syndrome and to identify those subsets of patients with acute coronary syndrome who may need to undergo invasive or conservative strategies. Method: A total of 100 patients with acute coronary syndrome including unstable angina, non-ST elevated myocardial infarction & ST elevated myocardial infarction were evaluated in National Institute of Cardiovascular Disease (NICVD), Dhaka with a view to correlate angiographic findings, C-reactive protein and WBC count. Results: This study observed that either raised WBC count or raised CRP independently and combination of both WBC count and CRP elevation were significantly associated with more severe coronary artery disease. Either raised WBC count or raised CRP or combination of raised WBC count and CRP were significant predictor of multivessel disease and high stenosis score. Conclusion: Elevation of WBC count and CRP in patients with acute coronary syndrome are associated with severe coronary disease. WBC count and CRP can be used as a new and even simpler tool for risk stratification in acute coronary syndrome.
ABSTRACT
Background and aims: Hypertension is a frequent and almost ubiquitous health disorder, prevalent both in developed and developing countries. Hyperinsulinemia and insulin resistance have been suggested to be closely associated with the pathogenesis of essential hypertension. However there is considerable controversy in this regards. The present study was designed to explore the relationship between serum insulin and serum ionized calcium in non diabetic and diabetic hypertensive subjects. Subjects and Methods: A total of 57 hypertensive and diabetic hypertensive patients attending out patients department of the BIRDEM and NICVD were included in the study. Fasting serum glucose was measured by glucose oxidase method, lipid profile was measured by enzymatic method. Serum insulin was measured by Enzyme Linked Immunosorbent assay (ELISA) method and serum ionized calcium by the Ion Sensitive Electrode (ISE) technique. Results: Glucose-insulin ratios were calculated as the index for insulin. Serum insulin (pmol/ml), Mean ± SD, 147 ± 48 in DC and 170 ± 80 in DH groups vs 118 ± 21 in NC and 120 ± 41 in EH groups, p= 0.023 and p= 0.031 respectively. Although, from the serum insulin results, the diabetic groups seemed to have insulin resistance, the glucose-insulin ratios in the two groups were significantly lower compared to nondiabetic groups (Glucose-insulin ratio, mmol/pmol, 0.066 ± 0.025 in DC, 0.074 ± 0.025 in DH vs 0.044 ± 0.11 in NC, 0.043 ± 0.012 in EH, p= 0.005 - 0.0001). The serum ionized calcium in the healthy subject, first time reported in the country by an up to date method (1.17 ± 0.05 M ± SD), were within the range found in healthy subjects of the other populations. No significant difference in the serum Ca2+ could be found between any of the study groups. Also, serum Ca2+ did not correlate with blood pressure, glucose or insulin in any of the study groups or with all the patients as a whole. Serum total cholesterol, triglyceride, HDLc and LDLc levels in the DC, EH and DH group did not show any significant difference compared to NC group and among the groups. The lipid abnormality as reflected by the mean LDL-HDL cholesterol ratios was the highest in the DH group but the differences were not statistically significant compared to the NC, DC and EH group. Conclusions: The data suggest the following conclusions: a) Serum ionized calcium level in our population is similar to that reported for other population. b) Serum glucose and insulin by themselves do not have any direct influence on serum ionized calcium. c) Non obese diabetes mellitus subjects in our population do not show insulin resistance as the primary defect. Rather, there is significant decompensation of the insulin secretory capacity in the subjects. d) Insulin resistance should be measured directly in relation to blood pressure and Ca2+ in appropriate groups of subjects to explore the relationship between insulin resistance, hyperinsulinemia and serum ionized calcium.
ABSTRACT
Background: Thrombolysis In Myocardial Infarction (TIMI) risk score, heart rate variability (HRV) and 24hour mean heart rate all are important predictor of prognosis after ST segment elevation myocardial infarction(STEMI). Correlation among these factors has not been studied thoroughly. Methods: This study was conducted in NICVD (National Institute of Cardiovascular Diseases), Dhaka, from July 2008 to June 2009. Total 105 STEMI patients were included in the study. TIMI risk score were calculated and each patient under went 24hour Holter monitoring. SDNN for HRV and mean RR interval for mean heart rate were recorded. Results : Ninety one patients (mean age 53.9 ± 10.8 years), 86.7% were males and 14( mean age 59.8 ± 8.8 years), 13.3% were female. Stratification of subjects by TIMI risk score shows that nearly 60% had risk score in the range of 3 – 7, 17. % between 0 – 2 and 24% 8 or more than 8.SDNN and RR interval stratified by TIMI risk score demonstrates that both the variables decreases significantly with the increase of TIMI risk score. Among the TIMI risk groups SDNN values were 120.0 ± 19, 871.0 ± 20.5 and 40.9 ± 6.4 msec in mild, moderate and high risk group respectively(p=<0.001). Mean RR were 836.8 ± 121.0, 776.7 ± 130.3 and 649.7 ± 75.5 msec in low, intermediate and high risk group respectively(p<0.001). There was a significant correlation between depressed SDNN and high TIMI risk score (r=.893, p=.001). High TIMI risk score also showed a negative correlation with mean RR interval (r=-574, p<0.001). Mean RR and SDNN show a perfect linear relationship (r = 0.657, p < 0.001). Conclusion: It was observed that depressed heart rate variability and increased 24-hours mean heart rate correlates with high TIMI risk score after acute ST-elevation myocardial infarction.
ABSTRACT
Mucoepidermoid carcinoma is an uncommon primary lung tumor. Mucoepidermoid carcinomas have been reported in all age group and equally in both sexes. A case of mucoepidermoid carcinoma histologically confirmed by biopsy is reported here. The patient is a 15 years old male presented with cough and dyspnoea for 5 days. Chest roentgenography showed segmental consolidation of right lower lobe. Chest computed tomography revealed a soft tissue mass with calcification within the lumen of lower trachea in precarinal location. The patient underwent thoracotomy for endotracheal mass and resection was done. Following operation, the patient is symptom free and follow-up CT scan shows normal tracheal outline.
