Chronic granulomatous disease (CGD) is a rare primary immunodeficiency disorder identified by recurrent pyogenic and fungal infections infections secondary to defective nicotinamide adenine dinucleotide phosphate oxidase enzyme. In the present study, we demonstrated a case with a history of multiple segmental lung resections because of invasive bronchopulmonary aspergillosis, multifocal hepatic and splenic granulomas, bilateral adnexal calcific foci presumed to be related with old granulomatous infection and finally gastric outlet obstruction secondary to the involvement of the stomach wall thickening with granulomatous tissue. This is an extremely severe case of CGD with multiorgan involvement within a 10-year period after the diagnosis. Gastric antral involvement may mimic inflammatory bowel diseases in such cases, and intestinal involvement can reliably be demonstrated via ultrasonography. Spontaneous resolution of the antral involvement was observed in the follow-up.

Acquired immune deficiency syndrome can be encountered with hypereosinophilia and hyperimmunoglobulin E (hyper-IgE) values, though these levels are rarely so high to be compared with hyperimmunoglobulin E syndrome. A 9-year-old boy presented with the complaint of fatigue, weakness, weight loss and generalized pruritic rash lasting for a year. He had frequent respiratory tract infections, wheezing episodes and urticarial skin lesions before that. On admission, he was cachectic and he had generalized lymphadenopathy, hepatosplenomegaly, oral moniliasis and pruritic rash all over his body. Laboratory evaluation revealed marked lymphopenia and hypergammaglobulinemia with extremely high IgE values (IgE: 59 300 kU/l). He was diagnosed with stage 4 human immunodeficiency virus (HIV) infection and started on antiretroviral treatment. In conclusion, HIV infection can be presented with increased IgE values.

Background: The aim of this study was to describe the clinical and epidemiological characteristics of pandemic influenza in hospitalized children. Methods: A total of 114 patients with suspected H1N1 virus infection were hospitalized, and nasal swabs were sent to National Influenza Reference Laboratory for confirmation of pandemic influenza A (H1N1) virus infection by rRT–PCR assay. Results: Forty-six female and 68 male patients were included in the study. Age of the patients ranged from 40 days to 16 years. Clinical and/or radiological pneumonia were detected in 96% of all. Sixteen patients required mechanical ventilation due to hypoxemia. Previously healthy children required mechanical ventilation and oxygen therapy more than patients with chronic diseases. Elevated levels of CRP and LDH in patients with respiratory distress and patients who required mechanical ventilation were statistically significant. Conclusion: Our study showed that progress of pandemic influenza infection in previously healthy children is as severe as their counterparts with chronic underlying diseases.

The objective was to investigate the role of Mycoplasma pneumoniae and Chlamydia pneumoniae infection in pediatric pneumonia in Istanbul Turkey we conducted a prospective study covering all the children between 2 months and 15 years hospitalized for community-acquired pneumonia. A total of 140 children (85 males median age 2.5 years) with community-acquired pneumonia were enrolled. Acute and convalescent sera were tested for IgM and IgG antibodies to M. pneumoniae (enzyme-linked immunosorbent assay Serion ELISA classic) and for IgM and IgG antibodies to C. pneumoniae (microimmunofluorescence Savyon Israel). Mycoplasma pneumoniae infection was diagnosed in 38 patients (27%) and C. pneumoniae infection in 7 (5%). In 2 children M. pneumoniae and C. pneumoniae co infection was observed. The average age of the M. pneumoniae cases was 5.3 years and that of the C. pneumoniae was 1.5 years. The average age of pneumonia cases caused by other pathogens was 3.4 years (p
