A rare cause of wheezing in an infant: Esophageal duplication cyst.

Esophageal duplication cyst (EDC) is classified as a subgroup of foregut duplication cyst. They are very rare and predominantly detected in children. We present an unusual cause of wheezing in a 2-month-old infant. The diagnosis of EDC was suspected by bronchoscopy, provisionally confirmed by magnetic resonance imaging, and followed by successful surgical excision of the cyst. We conclude that foregut duplication cyst of the esophagus is very rare, and must be considered in the differential diagnosis of persistent wheezing in infants who do not respond to conventional treatment.

Risk Factors and Predictors of Mortality in Critically ill Children with Extensively-Drug Resistant Acinetobacter baumannii Infection in a Pediatric Intensive Care Unit.

OBJECTIVE: Acinetobacter baumannii is an important emerging cause for extensively-drug resistant (XDR) hospital associated infections (HAIs) in pediatric intensive care units (PICU). The study was done to evaluate the risk factors, outcome, antibiotic sensitivity pattern, and predictors of mortality in critically ill children with XDR A. baumannii infection. METHODS: Retrospective case control study, done in the PICU of a tertiary care pediatric hospital of India from April 2010 to March 2012. FINDINGS: Eighty-five children who developed XDR A. baumannii infection matched to 170 controls. Majority (76%) of the organisms were isolated from endotracheal lavage. The mortality rate was 28.2% (24/85). The factors found to be significantly associated with A. baumannii infection were prior use of broad-spectrum antibiotics, major surgeries done, prolonged PICU stay, use of central venous catheters, and mechanical ventilation. The predictors of mortality associated with A. baumannii infection were acute kidney injury, presence of septic shock, and disseminated intravascular coagulopathy. Colistin found to be the single most effective drug against XDR A. baumannii infection. CONCLUSION: XDR A. baumannii infections are associated with high morbidity and mortality in critically ill children. Early diagnosis and treatment are crucial. Implementation of infection control practices and rational use of antibiotics are required to control such infections.

Delayed repair of posttraumatic bronchial transection.

Tracheobronchial injuries (TBI) are uncommon but potentially fatal injuries that can occur following blunt trauma to the thoracic region. Occasionally the diagnosis is not made at initial presentation, and patients present late with various sequelae. A 3 year old boy sustained blunt thoracic injury and developed respiratory distress, pneumothorax, and subcutaneous emphysema, which were managed conservatively with intercostal tube. Bronchoscopy performed to assess the cause of persistent collapse of the right lung and continued respiratory distress showed complete block of right main bronchus one cm away from the carina. Thoracotomy was performed and the transected ends of the bronchus were anastomosed. Postoperatively the right lung expanded with relief in respiratory distress. This report highlights the success of delayed repair of TBIs as an alternative to pneumonectomy.

Intravenous colistin for multidrug-resistant gram-negative infections in critically ill pediatric patients.

OBJECTIVES: Nosocomial infection due to multidrug-resistant Gram-negative pathogens in ICUs is a challenge for clinicians and microbiologists and has led to the resurgence of IV colistin use in the last decade. The aim of this study was to assess the efficacy of IV colistin in the treatment of critically ill children with multidrug-resistant Gram-negative infections. DESIGN AND SETTING: Retrospective descriptive study conducted in the PICU of Maulana Azad Medical College and associated Chacha Nehru Bal Chikitsalaya, Delhi, India, during the period of January 2010 to December 2011. PATIENTS: The records of critically ill children with multidrug-resistant Gram-negative infections treated with IV colistin were reviewed. RESULTS: Fifty critically ill children received IV colistin; their median age was 36 months (range: 1 mo-12 yr), with male:female ratio of 3:2. The isolated pathogens were Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, and Enterobacter cloacae. Mean duration of colistin therapy was 14.3 days (range, 7-21). A favorable clinical outcome occurred in 36 children (72%), and 14 children (28%) died due to severe sepsis with multiple-organ dysfunction syndrome. Renal toxicity occurred in five children and was associated with multiple-organ dysfunction syndrome in three and coadministration of vancomycin in two. No neurotoxic adverse effects due to colistin therapy were reported. CONCLUSION: Our study suggests that IV colistin may have a role in the treatment of infections caused by multidrug-resistant Gram-negative bacteria in critically ill children, but further prospective and randomized control trials are needed to confirm its efficacy and safety in children.
