ABSTRACT
Visual reaction time is time required to response to visual stimuli. The present study was conducted to measure visual reaction time in 209 subjects, 50 table tennis (TT) players and 159 healthy controls. Methods: The visual reaction time was measured by the direct RT computerized software in healthy controls and table tennis players. Simple visual reaction time was measured. During the reaction time testing, visual stimuli were given for eighteen times and average reaction time was taken as the final reaction time. Results: The study shows that table tennis players had faster reaction time than healthy controls. On multivariate analysis, it was found that TT players had 74.121 sec (95% CI 98.8 and 49.4 sec) faster reaction time compared to non-TT players of same age and BMI. Also playing TT has a profound influence on visual reaction time than BMI. Conclusion: Our study concluded that persons involved in sports are having good reaction time as compared to controls. These results support the view that playing of table tennis is beneficial to eye-hand reaction time, improve the concentration and alertness
ABSTRACT
Background: Hypertension is known to be risk factor for the development of proteinuria in patients with uncontrolled diabetes mellitus type2, leads to progression of end stage renal disease Aims & Objective: To study the effect of hypertension on diabetic nephropathy in type 2 diabetic patients. Material and Methods: We investigated, progression of diabetic nephropathy by measuring arterial blood pressure , serum creatinine and glomerular filtration rate(GFR) level in 60 (35 men and 25 women) type 2 uncontrolled diabetes mellitus patients on antihypertensive treatment. Results: The survey was done for 6 months during which 30 (group 1) -uncontrolled diabetes mellitus patients with normal blood pressure were compared with 30 (group 2) -Uncontrolled diabetes mellitus patients with hypertension who had mean systolic blood pressure (SBP) was 148.86 ± 5.12 mmHg. In group 2 the mean level of serum creatinine (1.71 ± 0.46 mg/dl) was significantly higher and mean GFR (54.57 ± 35.26 ml/min) was significantly lower than group 1 (P < 0.05). Conclusion: Uncontrolled hypertension leads to progression of diabetic nephropathy with decline in GFR earlier than normotensive uncontrolled diabetic patients.
ABSTRACT
Background & objectives: The effect of the hormonal changes associated with menopause on the serum lipid levels may play an important role in most cardiac related disorders associated with menopause. So the present study was undertaken with the following objectives. 1) To study the serum lipid profile in premenopausal and postmenopausal women. 2) To compare the differences of serum lipid profile between premenopausal and postmenopausal women. 3) To study the effect of duration of menopause on serum lipid profile. 4) To correlate the results of present study with that of other studies. Methods: 50 premenopausal and 50 postmenopausal women were recruited for the study. The subjects having risk factors that may affect the lipid profile were excluded. 5 ml of venous blood was collected after overnight fasting of 12 hrs in all the subjects for estimation of serum levels of total cholesterol, HDL, LDL, VLDL and triglycerides. Results: As compared to premenopausal women, mean level of serum total cholesterol and serum LDL were significantly higher in postmenopausal women and level significantly increased with increase in the duration of menopause. While level of serum HDL was significantly lower in postmenopausal women and level significantly decreased with increase in the duration of menopause. There was no statistically significant difference in serum triglycerides and serum VLDL between premenopausal and postmenopausal women up to 10 years duration of menopause. However they increased significantly after > 10 years duration of menopause. Interpretation & conclusion: According to the present study, menopause is associated with altered serum lipid profile and thus an independent risk factor for developing cardiovascular diseases. Therefore it is important to consider each and every postmenopausal woman to undergo screening for abnormal lipid profile. In them, specific health education strategies are needed in an order to prevent the emerging cardiovascular diseases.
ABSTRACT
OBJECTIVE: The long QT syndrome (LQTS) is a disorder of the electrical system of the heart, due to dysfunction of the ion channels and involving the repolarisation process. The inherited form occurs when there is a mutation in one of the genes which encode the making of a channel. Prolongation of the QT interval renders the patient vulnerable to an arrythmia called torsade de pointes, resulting in syncope and sudden death. METHODS: Three children with the congenital long QT syndrome presented to the pediatric department, one of them also having a 2:1 atrio-ventricular block. The parents and siblings of these children were screened for the long QT syndrome with an electrocardiogram. 2D echocardiography was done to rule out structural abnormalities and audiometry for deafness. RESULTS: Four family members were identified on screening to have LQTS. Propranolol was started on all children with LQTS. The child with heart block also received a pacemaker. LQTS must be considered in all patients presenting with syncope especially if associated with deafness and/or a family history of sudden deaths in infancy or childhood. CONCLUSION: The corrected QT interval must be determined in all children with heart block since the two conditions are often associated.
