ABSTRACT
To determine the frequency of Ventilator-Associated Pneumonia [VAP] and to identify the associated factors, causative organisms and outcome of VAP in children admitted to ICU. Cross-sectional, observational study. Medical ICU [MICU] of the Children/'s Hospital and Institute of Child Health, Lahore, from August 2008 to March 2009. All children admitted to MICU and requiring ventilation during the study period were included and monitored for any features suggestive of VAP. Partial septic screen was done in all suspected cases. VAP was labelled when any patient on the ventilator for more than 48 hours had at least 2 of the following features of nosocomial infection - fever > 101'F, TLC < 4000 or > 15000 per mm[3], neutrophils > 85%, CRP > 48 mg/L or new findings on chest examination suggestive of pneumonia' and radiological evidence of new or progressive and persistent infiltrates. Percentages were compared using chi-square test with the significance at p-value less than 0.05. Of the 93 children requiring mechanical ventilation during the study period, 16 developed VAP [17%]. Almost half [46%] were younger than 1 year with male to female ratio of 1.2:1. Children developing VAP required ventilation for 13.5 [+ 10.1] days compared to 7.7 [+ 5.5] days in those who did not develop VAP. The common organisms isolated were Pseudomonas, Klebsiella and E. coli. Factors associated with increased frequency of VAP included age less than 1 year, unplanned emergency intubation and use of continuous intravenous sedation. Features that strongly suggested underlying VAP included purulent tracheal secretions compared to increased secretions alone, CRP > 48 mg/L, positive radiological findings and positive tracheal aspirate culture. Overall mortality was 23% among the ventilated cohort. Thirty two percent of them had VAP compared to only 13% among those who survived to discharge [p = 0.03]. The frequency of VAP was 17% in this series. Factors significantly associated with VAP were age less than 1 year, unplanned intubation and continuous sedation. The important predictors of VAP included purulent tracheal secretions, high CRP and persistent new radiological findings
ABSTRACT
To determine the prognosis of seizures in epileptic children and identify early predictors of intractable childhood epilepsy. Case-control study. The Epilepsy Centre of the Children's Hospital Lahore, from February 2005 to April 2007. All children [aged 1 month to 16 years] with idiopathic or cryptogenic epilepsy who were treated and followed at the centre during the study period were included. The patients who had marked seizures even after two years of adequate treatment were labeled as intractable epileptics [cases]. Children who had no seizure for more than one year at last follow-up visit were the controls. Adequate treatment was described as using at least three anti-epileptic agents either alone or in combination with proper compliance and dosage. Records of these patients were reviewed to identify the variables that may be associated with seizure intractability. Of 442 epileptic children, 325 [74%] intractable and 117 [26%] control epileptics were included in the study. Male gender [OR=3.92], seizures onset in infancy [OR=5.27], >/= 10 seizures before starting treatment [OR=3.76], myoclonic seizures [OR=1.37], neonatal seizures [OR=3.69], abnormal EEG [OR=7.28] and cryptogenic epilepsy [OR=9.69] and head trauma [OR=4.07] were the factors associated with intractable epilepsy. Seizure onset between 5-7 years of age, idiopathic epilepsy, and absence seizures were associated with favourable prognosis in childhood epilepsy. Intractable childhood epilepsy is expected if certain risk factors such as type, age of onset, gender and cause of epilepsy are found. Early referral of such patients to the specialized centres is recommended for prompt and optimal management
