Background: Idiopathic thrombocytopenic purpura (ITP), also known as immune thrombocytopenic purpura is one of the commonest bleeding disorders encountered in children between the ages of 2 to 10 years affecting both sexes. The objectives of the study were to collect the prospectively data including age, gender, bleeding type, platelet count and other laboratory tests, treatments, responses to treatment and outcomes in children with acute ITP from 1month to 14 years of age over a period of two years.Methods: The present study was conducted in the Department of Paediatrics Shrirama Chandra Bhanj, Medical College and Hospital and Sardar Vallabhbhai Patel Post Graduate Institute of Paediatrics, Cuttack during the period October 2011-Septmber 2013.Results: Total 36 cases of hospitalized acute ITP patients were studied out of 29200 cases. Prevalence of acute ITP was found to be 12.3 per 10,000 of all hospitalized children above 1 month. Male children outnumbered female children by Ratio 1.2. Past history of URTI was present in 78% of cases. Petechaie/purpura was the universal presenting features followed by Oral / Gum bleeding in 67% of cases. 8% of patient experienced clinical bleeding requiring blood transfusion and platelet transfusion. Mean duration of Hospital stay was 6.34 days. Maximum number of Patients (69%) had complete recovery and 14% each had persistent and chronic course.Conclusions: ITP is a common pediatrics disease presenting at any age with low morbidity and mortality. Most children with acute ITP recover in weeks to months. A long-term hospital based prospective study is suggested to know any significant risk factor in patient presenting with acute ITP.

Recording of end-tidal carbon dioxide (EtCO2) noninvasively reflects a real-time estimation of arterial carbon dioxide (PaCO2 [partial pressure of CO2]). However, as the EtCO2 is dependent on metabolism, perfusion, and ventilation, predicting PaCO2 from EtCO2 is not linear. The objective of the study was to find out the predictability of PaCO2 from EtCO2 in PICU and to evaluate the factors affecting the correlation of EtCO2 and PaCO2 in critically ill ventilated children. The design involved was prospective observational study. The setting discussed over here is that of pediatric intensive care unit (PICU) of tertiary care hospital. A total of 160 children between 1 month and 14 years received mechanical ventilation. EtCO2, PaCO2, PaO2/FiO2 (PF) ratio, oxygenation index (OI), and ventilation index (VI) are the factors involved in main outcome measures. A total of 535 pairs of EtCO2 and PaCO2 were recorded in 160 ventilated children during the stable hemodynamic state. Mean age and weight (Z-score) of patients were 31.15 ± 40.46 months and −2.10 ± 1.58, respectively. EtCO2 and PaCO2 differences were normal (2–5 mm of Hg) in 393 (73.5%) pairs. High gradient (>5 mm of Hg) was mostly found with children with pneumonia, prolonged ventilation, and pressure mode of ventilation (p < 0.05). EtCO2 had a strong positive correlation with PaCO2 (r = 0.723, 95% confidence interval [CI] = 0.68 and 0.76) and not significantly affected by PF ratio or OI. However, presence of pneumonia and high ventilation index (VI > 20) adversely affected the relationship with poor correlation coefficient (r = 0.449, 95% CI = 0.30, 0.58 and r = 0.227, 95% CI = 0.03, 0.41, respectively). EtCO2 reading showed good validity to predict PaCO2 and not affected by oxygenation parameters. The correlation was affected by the presence of pneumonia and high ventilation index; hence it is recommended to monitor PaCO2 invasively in these patients till a good correlation is established.
