Idiopathic acute eosinophilic pneumonia in a 14-month-old girl.

Idiopathic acute eosinophilic pneumonia (IAEP), characterized by acute febrile respiratory failure associated with diffuse radiographic infiltrates and pulmonary eosinophilia, is rarely reported in children. Diagnosis is based on an association of characteristic features including acute respiratory failure with fever, bilateral infiltrates on the chest X-ray, severe hypoxemia and bronchoalveolar lavage fluid >25% eosinophils or a predominant eosinophilic infiltrate in lung biopsies in the absence of any identifiable etiology. We present a 14-month-old girl who was admitted to our pediatric intensive care unit because of acute respiratory distress.

Bronchodilator responses after methacholine and adenosine 5'-monophosphate (AMP) challenges in children with asthma: their relationships with eosinophil markers.

Background: Bronchodilator responsiveness (BDR) and eosinophilic inflammation are characteristic features of asthma. Objective. The aim of this study was to compare the relationships of BDR after methacholine challenge or adenosine 5'-monophosphate (AMP) challenge to blood eosinophil markers in children with asthma.

Severe osteomyelitis as a complication of Tokyo-172 BCG vaccination.

The bacilli Calmette-Guérin (BCG) Tokyo-172 strain was considered to exhibit good protective efficacy with a low rate of unfavorable side effects. However, we describe a rare case of BCG osteomyelitis developed in an immunocompetent host who was given with BCG Tokyo-172 vaccine on the left upper arm by multipuncture method. A 9-month-old girl presented with progressive inability to move her right elbow and had radiographic evidence of septic elbow combined with osteomyelitis of right distal humerus.
