Background: Coronary artery diseases are one of the major challenges faced by cardiologists. Control of certain risk factors for CAD is associated with decrease in mortality and morbidity from myocardial infarction and unstable angina. So, identification and taking appropriate measures for primary and secondary prevention of such risk factors is, therefore, of great importance. This retrospective study was carried at the newly set up cath lab in Dhaka Medical college. Materials and Methods: Total 228 consecutive case undergone diagnostic coronary angiogram from 10th January 2007 to31st January 2009 out of which 194(80%) were male and 34 (20%) were female. In both sexes most of the patients were between 41 to 60 years of age. Risk factors of the patients were evaluated. Results: In females commonest risk factor was Diabetes (58.8%) followed by dyslipidaemia (35.3%). In males commonest risk factor was hypertension (30.9%) followed by smoking (29.9%) and diabetes (28.3%). In males 44.3% patients presented with acute myocardial infarction followed by stable angina (43.3%); but in females stable angina was the commonest presentation (50.0%) followed by myocardial infarction (38.2%).CAG findings revealed that in males 33.5% had double vessel disease 26.8% followed by single vessel 26.8% and multivessel disease 25.3%. In females normal CAG was found in 35.5% followed by double vessel 23.5%, multivessel 20.6% and single vessel 20.6%. On the basis of CAG findings; in males 41.8% patients were recommended for CABG, followed by PTCA & stenting 26.3% and medical therapy 30.0%; where as in females 55.9% were recommended for medical therapy , followed by CABG 32.4% and PTCA & stenting11.8%. Conclusion: The commonest presentation of CAD was 4th and 5th decades in both sexes. Diabetes and dyslipidaemia were more common in females whereas hypertension and smoking were more common in males. Myocardial infarction and stable angina were most common presentation in both sexes though in males myocardial infarction was more common. In males the angiographic severity of CAD was more and they were more subjected for CABG in comparison to females.

The study was carried out to see the etiology and outcome of chronic renal failure in children. It is a prospective study, carried out to evaluate all new cases of CRF in children < 15 years in nephrology unit of BSMMU from May 2000 to May 2002. Diagnosis of CRF was based on Ccr < 75 ml/min/m(2) along with other features of CRF with no evidence of recovery over ensuing three months. A total of 44 children with CRF having mean age of 8.73 3.56 years were diagnosed during study period, among them, 30 cases (68.19%) were male and 14 cases (31.81%) were female. Causes of CRF were obstructive uropathy in 24 cases (54.55%) followed by glomerular diseases in 15 cases (34.9%), hereditary disorders in 3 cases (6.81%), and reflux nephropathy in 2 cases (4.54%). At presentation, 13 (29.55%) children had mild to moderate CRF and 31 (70.45%) children had severe CRF and ESRD. Mean follow up period was 32.3 weeks. At the end of the study period, 8 patients of mild to moderate CRF were on conservative treatment, 6 patients of severe CRF and ESRD group attended for maintenance dialysis irregularly of which 3 died at hospital and rest of the patients did not attend at follow up due to financial reason or opted against IPD. In the present study, majority of the children with CRF is due to treatable obstructive uropathy; mostly PUV and most of them presented with advanced renal disease.

A prospective study was carried out to assay the level of serum intact parathormone and its correlation with biochemical parameters in patients with chronic renal failure (CRF). The study included 64 children (44 with CRF, and 20 age and sex matched controls). Serum intact parathormone (iPTH), serum creatinine, urea, calcium, inorganic phosphate and alkaline phosphatase were estimated. Creatinine clearance (Ccr) was estimated by Schwartz formula. Patients with CRF were divided into four groups based on their Ccr (mild CRF with mean Ccr 59.17 +/- 1:18.53 mL/min/1.73 m2 (n = 6) moderate CRF with mean Ccr 34.98 +/- 7.75 mL/min/1.73 m2 (n = 7); severe CRF with mean Ccr 17.71 +/- 5.40 mL/min/1.73 m2 (n = 15); and end-stage renal disease with mean Ccr 6.46 +/- 1.71 mL/min/1.73 m2 (n = 16). Mean serum iPTH levels were 93.00 +/- 46.62 pg/mL in CRF and 16.52 +/- 9.35 pg/mL in controls. Groupwise mean serum (iPTH) levels were 48.50 +/- 4.76, 67.29 +/- 7.91, 82.42 +/- 9.67 and 130.66 +/- 58.74 pg/mL in mild, moderate, severe CRF and endstage renal failure respectively. Mean serum iPTH level of CRF (93.00 +/- 46.42 pg/mL) negatively correlated with mean Ccr (22.02 +/- 18.53 mL/min/l.73 m2) (P < 0.001) and mean serum calcium (7.30 +/- 1.02 mg/dL) (P < 0.001) and positively correlated with mean inorganic phosphate (5.76 +/- 1.1 mg/dL) (P < 0.05) and mean alkaline phosphatase (355.14 +/- 185.53 UL) (P < 0.001). We conclude that increased iPTH level occur even early in the course of CRF and progressive hypocalcemia and hyperphosphatemia are the initiating factors for the development of hyperparathyroidism.

Infants born for small for date (SFD) fetuses have an increased risk of perinatal mortality and morbidity. Different methods have been applied to identify these fetuses including history, clinical examination and ultrasonography. Ultrasonography has a better predictive value and majority of such fetuses can be identified. Measurements of the fetal biparietal diameter (BPD), abdominal circumference (AC) and femur length (FL) charts are widely used in dating pregnancies and follow-up of pregnant women in assessing fetal growth, identification of small for date (SFD) and growth retarded fetuses. This prospective study was performed to construct fetal chart for BPD, AC and FL at different gestational weeks from the Bangladeshi pregnant women. Seven hundred and ten women had ultrasonic measurements of fetal BPD, AC and FL between 12 to 42 weeks of pregnancy. Centiles, mean and the standard deviation (SD) were calculated for BPD, AC and FL. Mean maternal age was 24.73 +/- 4.48 (Mean +/- SD) and 310 (43.7%) were primigravidae. There was a gradual increase of the BPD (outer-inner), AC and FL measurements of 5th, 10th, 50th and 90th Centiles upto 38th weeks of gestation with a gradual increase of SD showing increasing dispersion of data. In cases of BPD and AC, After 38th weeks of gestation the Centiles showed a slower growth rate towards 42 weeks of pregnancy. This slower growth rate from 38 weeks of pregnancy was not noted in case of femur length. Fetal charts with the raw data for each measurement with superimposed fitted lines derived from polynomial (quadratic) regression were constructed. Quadratic model showed good fit to the data during construction of fetal charts. The new fetal measurement charts of BPD, AC and FL are unique for the Bangladeshi population and have not been found similar in the later weeks of pregnancy to those published for other Caucasian populations. These charts will help the clinicians and sonographers in dating pregnancy, identifying SFD and growth retarded fetuses.

Newborn screening for early diagnosis of many preventable diseases is already an established program in developed countries as well as in some countries in Asia. With the control of infectious and communicable diseases, the Bangladesh government is now giving more attention to the preventive aspect of health. The country is now preparing to adopt newborn screening as part of the preventive aspect of health. Among the various activities are laboratory set up, expert visits, pilot studies on CH and training of personnel. A national project to screen newborns for congenital hypothyroidism is now under active consideration. A universal newborn screening program is a highly ambitious project for a country like Bangladesh. Funds to run such a program will be the main problem. The social pattern where still more than 80% of deliveries are done at home is another constraint. However, the enthusiasm of the professionals as well as of the government is a very encouraging thing. Now it needs the support of the international communities.

One hundred cases of solitary thyroid nodules attending the thyroid clinic, Institute of Postgraduate Medicine & Research, Dhaka (IPGMR) and the Institute of Nuclear Medicine (INM) were included in a prospective study. Thyroid ultrasonography (USG), scintiscanning, radioactive iodine (I131) uptake (RAIU), estimation of serum total T3, T4 & TSH and Fine Needle Aspiration Cytology (FNAC) were performed in all cases. Surgical resection with histopathologic study was performed in selected cases. Extra-nodular part of the thyroid gland was normal in 68 and diffusely enlarged in 32, RAIU was normal in 62, high in 36 and very low in two subjects. Nodules were solid at USG in 67 subjects, cystic in 16 subjects and of mixed consistency in 17 subjects. Goitrous subjects had significantly lower T4 (p < 0.001) and higher T3 (p < 0.01) and TSH (p < 0.001) than non-goitrous ones. Colloid nodule was the commonest pathology occurring in 41 cases, followed by thyroid cysts (26), follicular adenoma (23), adenoma with cystic change (7), subacute thyroiditis (2) and papillary carcinoma (1). Colloid nodules were more common in goitrous subjects which could hint at iodine deficiency as the major cause of such nodules. Hyperfunctioning follicular adenomas occurred exclusively in non-goitrous subjects. Carcinoma appeared to be uncommon in patients with solitary nodules. It gives an opportunity to our physicians to be more conservative in selecting patients with solitary thyroid nodules for surgical treatment.

Physiological responses to exercise were measured in 39 males [19-45 years old] working as cleaners in the Faculty of Medicine, Kuwait University. There was a graded reduction in maximum oxygen intake [VO2 max] of smokers. This reduction was greatest in those who smoked 20 or more cigarettes per day. A statistically significant decrease [p <0.05] was recorded in forced expiratory volume [FEV1] and forced vital capacity [FVC] between smokers and nonsmokers. The results of this study provide quantitative evidence of the adverse effect of smoking on physical working capacity and show the impairment of ventilatory capacity caused by smoking
