ABSTRACT
Asthma attacks are serious respiratory problem that can be lethal when not treated appropriately. Till today the main stay of therapy is short acting ß2-agonist. Unfortunately in acute asthma episodes this is not enough to relieve the bronchospasm and reduce dyspnea. The shortcoming of ß2-agonist therapy has resulted in the use of a variety of other treatment in the management of acute asthma. The use of magnesium sulphate is one of the recent treatment options. This study was done to compare the efficacy of nebulized salbutamol with magnesium sulphate versus salbutamol with normal saline in the treatment of acute exacerbation of asthma in children. This randomized controlled trial was carried out among 60 patients with acute exacerbation of bronchial asthma fulfilling the inclusion criteria, admitted in the department of Paediatrics, Mymensingh Medical College Hospital over a period of one year from January 2009 to December 2009. They were distributed randomly, 30 patients received nebulized salbutamol (0.15mg/kg; minimum dose 2.5mg) with 2.0 ml of isotonic magnesium sulphate solution and another 30 patients received the same dose of salbutamol with 2.0 ml of normal saline on 3 occasions at 20 minute intervals. With single dose of nebulization in the magnesium sulphate with salbutamol group, by 20 minute almost all 26 (86.7%) patients achieved at least 60% of predicted PEFR. Within 20 minute from control group none could achieve 60% of predicted PEFR. After second dose of nebulization control group started achieving 60% of predicted value. Regarding response criteria, with second dose of nebulization, at 40 minute 16 (53.3%) patient from magnesium sulphate with salbutamol group showed good response (PEFR>70% predicted). But within the first 40 minutes, none could show good response in control group. With 3rd dose of nebulization all from magnesium sulphate group showed good response but even at 60 minute, 5 (16.7%) patients in control group failed to be included as good responder. In conclusion, nebulization by isotonic magnesium sulphate solution with salbutamol provide early and better response as compared to conventional approach (salbutamol plus normal saline) in acute exacerbation of asthma in children.
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
Anti Phospholipid Syndrome (APS) is a relatively new conception of syndrome complex first noticed in 1983. It may be primary or secondary to other diseases like SLE, RA, Systemic sclerosis, behchet's syndrome, temporal arteritis, sjogren's syndrome psoriatic arthropathy etc. Clinical manifestations are consequences of vascular thrombosis and embolism like DVT, pulmonary embolism, stroke, TIA, complication of pregnancy with pregnancy loss. We report a 34 years married female housewife who presented with sudden onset of nausea, vomiting, vertigo, dysphagia, dysarthria and ataxia. She had a chronic leg ulcer. Neurological findings were consistent with lateral medullary syndrome due to stroke though she was normotensive, nondiabetic with normal lipid profile. She had history of two abortions in last three years. Investigations were done accordingly and she fulfilled the diagnostic criteria of APS. No secondary cause was detected after thorough clinical examination and laboratory investigations. She was treated symptomatically along with oral anticoagulation. She improved slowly but steadily.
