[Central nervous system histoplasmosis in an immunocompetent pediatric patient].

Neurohistoplasmosis is a rare disease, most prevalent in immunosuppressed patients, secondary to disseminated disease with a high mortality rate when diagnosis and treatment are delayed. We report a previously healthy 12 year old girl, from a bat infested region of Tucuman Province, Argentine Republic, who developed meningoencephalitis due to Histoplasma capsulatum. Eighteen months prior to admission the patient started with headaches and intermittent fever.

High mortality in patients with influenza A pH1N1 2009 admitted to a pediatric intensive care unit: a predictive model of mortality.

Objective: To describe the clinical characteristics and outcome of patients admitted to pediatric intensive care with influenza A (pH1N1) 2009 in Argentina.

Design: Retrospective observational study.

Setting: Thirteen pediatric intensive care units in Argentina.

Hospital-acquired hyponatremia in postoperative pediatric patients: prospective observational study.

Objective: To establish the incidence and factors associated with hospital-acquired hyponatremia in pediatric surgical patients who received hypotonic saline (sodium 40 mmol/L plus potassium 20 mmol/L) at the rate suggested by the Holliday and Segar's formula for calculations of maintenance fluids.

Design: Prospective, observational, cohort study.

Setting: Pediatric intensive care unit.

[Transpyloric feeding tube placement by gastric air insufflation technique in pediatric intensive care patients].

Introduction: The aim of the study was to evaluate the success rate of transpyloric tube (TPT) placement using air gastric insufflation technique in patients hospitalized in the Pediatric Intensive Care Unit. POPULATION, MATERIALS AND METHODS: The data were collected retrospectively from a prospective filled database. TPT positioning was defined as successful by evaluation of its distal end in the abdominal X-ray.

Adequate agreement between venous oxygen saturation in right atrium and pulmonary artery in critically ill children.

Objective: To determine the agreement between venous oxygen saturation in right atrium (Srao2) and pulmonary artery (Svo2) in critically ill pediatric patients.

Design: Retrospective, observational study.

Setting: Multidisciplinary pediatric intensive care unit from a general university hospital.

Internal mammary artery injury after central venous catheterization.

Objective: We describe an infrequent but potentially lethal complication: an iatrogenic injury of the internal mammary artery after central venous catheterization.

Design: Report of cases.

Setting: Pediatric intensive care unit.

Validation of pediatric index of mortality 2 (PIM2) in a single pediatric intensive care unit of Argentina.

Objective: Pediatric Index of Mortality 2 (PIM2) is an up-to-date mortality prediction model in the public domain that has not yet been widely validated. We aimed to evaluate this score in the population of patients admitted to our pediatric intensive care unit.

Design: Prospective cohort study.

Jugular venous oxygen saturation or arteriovenous difference of lactate content and outcome in children with severe traumatic brain injury.

Objective: To assess the association between neurologic out-come and the alterations of jugular venous oxygen saturation (SjvO2) or the increase in arteriovenous difference of lactate content (AVDL) in children with severe traumatic brain injury.

Design: Observational prospective cohort study.

Setting: Multidisciplinary pediatric intensive care unit of a university hospital.
