ABSTRACT
A-13-year-old girl presented with diabetic ketoacidosis with convincing clinical signs of parotitis (fever, drooling of saliva, inability to swallow with development of bilateral parotid swelling) and pancreatitis (fever, abdominal pain and vomiting), along with high serum amylase and positive mumps IgM titer. This suggests that mumps virus may have been the causative factor, probably as a result of concomitant involvement of the pancreas
ABSTRACT
Severe malnutrition can significantly compromise autonomic nervous system. However, less is known about the cardiac autonomic activity in mild and moderate grades of malnutrition in children. Therefore, the objective of this study was to assess the effect of mild/moderate malnutrition on heart rate variability (HRV), a non invasive tool to estimate the cardiac autonomic activity. A cross sectional, community based study was conducted in which 35 malnourished children (mean age: 6.06±2.04 yrs), on the basis of anthropometric parameters, were enrolled in the study group by random samplings, who were the children of urban slum dwellers and 35 age and sex matched healthy children, were taken as controls. Grading of malnutrition was done according to Indian Academy of Pediatrics (IAP) classification. Anthropometry, basal heart rate (BHR), blood pressure were determined. Time domain and frequency domain indices of HRV were assessed using RMS Polyrite D (version 2.4). Weight, height, mid arm circumference (MAC) and body mass index (BMI) were found to be statistically lower in the study group. There was a strong negative correlation between MAC and LF component (P<0.01). BHR was found to be increased in the malnourished group (P=0.027). Low frequency (LFnu) & LF-HF ratio were found to be increased (P=0.000 & P=0.001 respectively) while high frequency (HFnu) component was decreased (P=0.000) in malnourished group. Our results suggested that impaired cardiac autonomic nerve function characterized by sympathetic over activity may occur in malnourished children. This study also enables us to compare, in future works, HRV in pediatric subjects with different grades of malnutrition.
ABSTRACT
Various studies have reported the effect of severe malnutrition on electrolyte levels and electrocardiographic parameters. However, only a few have reported these findings in mild and moderate grades of malnutrition in children. Therefore, the objective of this study was to assess the effect of malnutrition (mainly mild and moderate grades) on corrected QT interval (QTc) and QT dispersion (QTcd) and electrolyte changes. A total of 20 malnourished children in the age group of 2-11 yrs were enrolled in the study group and 20 age and sex matched healthy children were taken as controls. Anthropometry, serum levels of albumin & electrolytes were determined. QTc and QTcd (difference between maximum & minimum corrected QT interval) were measured with the help of RMS Polyrite D. Our results have shown that body weight, height, body mass index (BMI), serum levels of albumin, potassium & calcium were lower (P<0.01) in malnourished children. QTc (P<0.01) & QTcd (P<0.01) were significantly greater in malnourished children than controls. We concluded that increase in QTc and QTcd intervals is associated with electrolyte disturbances in malnourished children. Electrolyte disturbance correction and appropriate nutrition therapy followed by further cardiac evaluation must be taken into account in the management of these patients.
ABSTRACT
Objective. To compare efficacy and tolerability of levosalbutamol (Group 1) and racemic salbutamol (Group 2) for the treatment of acute exacerbation of asthma in children age 5 to 18 yr. Methods. A randomized double blind clinical study involving 60 children was undertaken between October ’06 to December ’07. Results. The following baseline clinical characteristic were recorded initially and after giving 3 nebulizations at 20 min intervals in the Ist hour of presentation viz respiratory rate (RR), heart rate (HR), oxygen saturation in room air SPO2, PEFR (peak expiratory flow rate), serum K+ level and asthma score. In Group 1 patients (levosalbutamol), there was significant increment in SPO2 and PEFR (P<0.05) values with decrease in tachypnea and asthma score while no significant difference was found in pre and post treatment HR & Serum K+ levels. In Group 2 patients although there was clinical improvement in terms of SPO2, PEFR, RR and asthma score, it resulted in significant tachycardia and decrease in K+ levels. Conclusion. Levosalbutamol appears to be more efficacious than racemic salbutamol in terms of improvement in PEFR, SPO2 and asthma score while deleterious effects of tachycardia and fall in serum K+ were seen with racemic salbutamol.
