Introduction: Prolonged rupture of membrane (PROM) is an important risk factor for early onset neonatal sepsis (EONS), which is associated with increased neonatal morbidity and mortality. We reported the incidence and associated risk factors of PROM for culture-proven EONS. Methodology:The medical records of all neonates born at Aga Khan University, Karachi over a period of five years (2007)(2008)(2009)(2010)(2011) with PROM (> 18 hours) were reviewed. Data about maternal and neonatal risk factors for EONS was collected and adjusted logistic regression (AOR) analysis was applied. Results:Incidence of PROM in this neonatal birth cohort was 27/1,000 live births. A total of 17 (4%) cases with blood-culture proven bacterial sepsis were identified within 72 hours of birth. Klebsiella pneumonia (n = 5; 29%) and Pseudomonas aeruginosa (n = 4; 24%) were the commonest isolates followed by group B Streptococcus (n = 3; 18%) and Escherichia coli (n = 2; 12%). Maternal fever (p = <0.001; AOR, 36.6), chorioamnionitis (p < 0.001; AOR, 4.1), PROM > 48 hr. (p < 0.001; AOR, 8.2), neonatal prematurity < 34 weeks (p < 0.001; AOR, 4.1) and low birth weight < 1,500 grams (p 0.001; AOR, 9.8) along with neonatal thrombocytopenia and raised CRP were found to be independent risk factors associated with culture-proven EONS in PROM. Conclusions: Preventive measures should focus on recognition of these high-risk infants with prompt laboratory screening for sepsis and early institution of empirical antibiotic based on local data. Such approaches would be a safe and cost-effective strategy, especially in developing countries.
ObjectivesTo identify anthracycline-induced acute (within 1 month) and early-onset chronic progressive (within 1 year) cardiotoxicity in children younger than 16 years of age with childhood malignancies at a tertiary care centre of Pakistan.DesignProspective cohort study.SettingAga Khan University, Karachi, Pakistan.Participants110 children (aged 1 month–16 years).InterventionAnthracycline (doxorubicin and/or daunorubicin).Outcome measurementsAll children who received anthracycline as chemotherapy and three echocardiographic evaluations (baseline, 1 month and 1 year) between July 2010 and June 2012 were prospectively analysed for cardiac dysfunction. Statistical analysis including systolic and diastolic functions at baseline, 1 month and 1 year was carried out by repeated measures analysis of variance.ResultsMean age was 74±44 months and 75 (68.2%) were males. Acute lymphoblastic leukaemia was seen in 70 (64%) patients. Doxorubicin alone was used in 59 (54%) and combination therapy was used in 35 (32%). A cumulative dose of anthracycline <300 mg/m2 was used in 95 (86%). Fifteen (14%) children developed cardiac dysfunction within a month and 28 (25%) children within a year. Of these 10/15 (66.6%) and 12/28 (43%) had isolated diastolic dysfunction, respectively, while 5/15 (33.3%) and 16/28 (57%) had combined systolic and diastolic dysfunction. Seven (6.4%) patients expired due to severe cardiac dysfunction. Eight of 59 (13.5%) children showed dose-related cardiotoxicity (p=<0.001). Cardiotoxicity was also high when the combination of doxorubicin and daunorubicin was used (p=0.004).ConclusionsIncidence of anthracycline-induced cardiotoxicity is high. Long-term follow-up is essential to diagnose its late manifestations.
Introduction:Coronary artery involvement is the most dreaded long-term complication of Kawasaki disease. Our aim was to look at the pattern of cardiovascular involvement in Pakistani children admitted with Kawasaki disease.Methods:This study included children admitted with Kawasaki disease at the Aga Khan University Hospital Karachi over a period of 14 years from January 1997 to December 2010. Information gathered included patient demographics, clinical features, investigations, echocardiographic findings, treatment and follow-up. Those with coronary artery involvement on initial echocardiogram remained on long-term follow-up with clinical examination and echocardiogram.Results:A total of 56 patients were admitted. (Mean age at diagnosis 33 ± 30 months, age range 2 months to 9 years). 18% of patients had incomplete features. Twenty-five percent (14/56) patients presented after 10 days of fever. Cardiac examination was normal except for tachycardia. Abnormal coronary arteries were seen in 23 patients (41%) - left main coronary artery in 23 (41%), left anterior descending and right main coronary artery in 20 (36%), circumflex branch in 17 (30%). Risk factors for cardiac involvement were male sex, fever >10 days duration at the time of initial presentation and neutrophil percentage >75% in the initial white blood cell counts. Fifty four of 56 cases received intravenous immunoglobulin (IVIG), Seventy-five percent of the patients received IVIG within 10 days of illness. Mean duration of follow-up was 2.5 years. Eight percent of the patients still continue to have abnormal coronaries. There was no mortality.Conclusions:A higher incidence of coronary artery involvement was found in our study. Presentation after 10 days of illness increases the risk of coronary artery involvement. High index of suspicion among the general pediatricians about the disease can possibly be helpful for early referral and treatment.
Introduction: Varicella zoster infection(VZI) is well recognized as a potential cause of morbidity and mortality in immunocompromised pediatric oncology patients (POP). The purpose of this study was to describe the clinical profile and risk factors for complications and outcomes of VZI in POP treated with acyclovir. Methodology: Medical records of all POP with a discharge diagnosis of VZI over a period of seven years (2005)(2006)(2007)(2008)(2009)(2010)(2011) were reviewed. The demographic features, underlying malignancy, risk factors for VZI, complications, and outcomes were recorded. Results: Thirty-six POP with VZI were identified. Leukemia was the most common underlying malignancy (n = 20, 58.8%), followed by lymphoma (n = 7, 20.6%) and solid organ tumors (n = 7, 20.6%). Most of the cases (41%) were observed in children under five. All patients were treated with acyclovir. Varicella-related complications developed in 10 (29%) patients. The most frequent complication was bloodstream infection (n = 3, 8.8%), followed by pneumonia (n = 2, 5.9%), skin infection (n = 2, 5.9%), hepatitis, renal failure, and encephalitis. Independent risk factors associated with complications were age < five years, weight for age < fifth percentile, delay in seeking care (> seven days after onset of symptoms) and severe neutropenia (ANC < 500/cm). One child died secondary to varicella encephalitis. Conclusion: Our data suggests that young age, poor health-seeking behavior, severe neutropenia, and being underweight are the major risk factors for the development of varicella-related complications in POP in developing countries. These complications could be favorably modified through active immunization of immunocompetent children.
