Presumed adrenal insufficiency in neonates treated with corticosteroids for the prevention of bronchopulmonary dysplasia.

OBJECTIVE: To determine if extremely preterm (EPT) neonates receiving dexamethasone for the prevention of BPD have a higher incidence of presumed adrenal insufficiency (PAI). STUDY DESIGN: Retrospective cohort study of neonates <28 weeks gestation examining PAI after dexamethasone use and PAI after intratracheal budesonide with surfactant administration. RESULT: Of 332 neonates, 38% received dexamethasone. The incidence of PAI was higher in neonates who had received dexamethasone (20.8% vs 2.9%, p < 0.001). However, for intubated babies receiving surfactant, dexamethasone was not independently associated with increased PAI after adjusting for gestational age, birthweight, and race (aOR 2.92, 95% CI: 0.79-10.85). Dexamethasone was independently associated with increased PAI in infants previously receiving budesonide/surfactant treatment (aOR 5.38, 95% CI: 1.38-20.90). CONCLUSION: The use of dexamethasone alone was not associated with increased PAI, when adjusted for prematurity-related factors. The combination of budesonide with dexamethasone was significantly associated with increased PAI.

Nebulized Gentamicin as an Alternative to Nebulized Tobramycin for Tracheitis in Pediatric Patients.

OBJECTIVES: Tracheitis is an infection of the lower respiratory tract and is defined by the US Centers for Disease Control and Prevention (CDC) based on signs and symptoms with no radiographic evidence of pneumonia. One method of treatment involves the use of tobramycin given by nebulizer. The purpose of this study was to compare the safety and efficacy of nebulized gentamicin with nebulized tobramycin. METHODS: This study was conducted in patients under 21 years of age who received greater than or equal to 1 day of gentamicin, 80 mg, or tobramycin, 300 mg, given twice a day by nebulization within the 14-month study period. The primary endpoint was amount of time until the patient no longer met the CDC definition of tracheitis. RESULTS: There were 19 patients who presented with 60 separate encounters. The average age of the patients within the gentamicin group was 7.2 and 5 years old within the tobramycin group. The average duration of time for the gentamicin treatment encounters to be free of the CDC definition of tracheitis was 3.36 days compared to 3.17 days with tobramycin. No adverse effects were observed that were attributable to aminoglycoside nebulization. CONCLUSIONS: No differences were detected between the safety and efficacy of intravenous gentamicin administered twice a day by nebulizer and that of tobramycin inhalation solution given twice daily in children without cystic fibrosis.

Prevalence and treatment of metabolic syndrome in adolescents with type 2 diabetes.

BACKGROUND: The incidence of obesity and type 2 diabetes among adolescents has risen dramatically in recent years, and it is likely that many of these adolescents also have metabolic syndrome. OBJECTIVE: To investigate the prevalence of metabolic syndrome in the patient population enrolled in a children's hospital type 2 diabetes clinic and to describe baseline pharmacologic treatment and adherence patterns. METHODS: In this retrospective cohort study, the medical charts of 52 adolescents were reviewed. A data collection instrument was used to collect demographic data, laboratory values, medication lists, and documented adherence patterns from the patient's initial clinic visit. Data collected were used to identify patients with metabolic syndrome. Data were entered into a database and analyzed using SPSS 13.0. RESULTS: Data were collected for 52 patients; of these, 40 (76.9%) had characteristics of metabolic syndrome meeting 3 or more of the 5 criteria, although only 8 (15.4%) were diagnosed with the metabolic syndrome. Among patients with characteristics of metabolic syndrome, 92.5% were taking a glucose-lowering drug, with 85% of those receiving metformin. Sixteen (40%) patients were receiving a blood pressure-lowering medication at baseline, and 4 (10%) were taking a lipid-lowering agent. Forty-three percent of these patients reported nonadherence to their prescribed drugs. CONCLUSIONS: Given these treatment patterns, pharmacologic management of metabolic syndrome in adolescents with type 2 diabetes may be suboptimal and may impact cardiovascular outcomes. It is important for clinicians to be aware of the incidence of type 2 diabetes and metabolic syndrome in adolescents so that treatment with lifestyle modifications and pharmacologic therapy may be implemented earlier.
