Risk of systemic allergic reactions to allergen immunotherapy in a pediatric allergy clinic in Turkey.

Objectives: Even though allergen immunotherapy is an effective treatment method that has been used on rhinitis, asthma and venom anaphylaxis for over 100 years, systemic reactions (SRs) limit the use of this treatment method. We classified SRs associated with subcutaneous immunotherapy (SCIT) according to the World Allergy Organization Subcutaneous Immunotherapy Systemic Reaction Grading System. Risk factors for the SRs were assessed.

Steroid-induced psychosis in a child: treatment with risperidone.

Steroid-induced psychosis is one of the most serious adverse effects of steroid therapy but is a little-known complication in children. There is no clear mechanism model for steroid-induced behavioral disturbance, but it may be related with dose or level of free fraction of steroids. Our case is a 12-year-old boy diagnosed with steroid-induced psychosis and treated with risperidone, an atypical antipsychotic, due to distinct psychotic symptoms.

Evaluation of chronic cough in children.

Chronic cough in children is among the problems that lead to frequent consultations with a doctor. In this study, we attempted to research the reasons for chronic cough by an evaluation method using the guidelines that were suggested for children by the American College of Chest Physicians (ACCP) in 2006. We studied 108 children between 6 and 14 years of age who had a cough that lasted for > 4 weeks.

Nephrocalcinosis in glucose-galactose malabsorption: nephrocalcinosis and proximal tubular dysfunction in a young infant with a novel mutation of SGLT1.

We report an association of proximal renal tubular dysfunction in a 50-day-old girl with glucose-galactose malabsorption who was found to have nephrocalcinosis, but no sign of nephrolithiasis. A novel homozygous nonsense mutation at 267Arg-->stop (CGA-->TGA) in the Na(+)-dependent glucose transporter (SGLT1) was found in loop 5 connecting transmembrane segments 6 and 7, indicating the complete loss of glucose transport activity. This case indicates that hypercalcaemia, nephrocalcinosis and proximal tubular dysfunction may be seen in association with glucose-galactose malabsorption and that most of these abnormalities improve with a glucose-galactose-free diet.

FcgammaRIIIa-V/F 158 polymorphism in Turkish children with asthma bronchiale and allergic rhinitis.

Fc receptors (FcR) play an important role in immune regulation. This might be linked to the variability in immune response, therefore relating to the pathogenesis of atopic diseases. The aim of the present study was to evaluate the FcgammaRIIIa gene polymorphism in Turkish children with asthma and allergic rhinitis.

Development of new sensitizations in asthmatic children monosensitized to house dust mite by specific immunotherapy.

It has been hypothesized that specific immunotherapy (SIT) significantly decreases the development of new allergen sensitizations in mono-sensitized patients. In this study, we evaluated the effect of SIT on the development of new allergen sensitizations in 129 asthmatic children mono-sensitized to house dust mite. SIT was accepted by only 70 of them (SIT group).

Prognostic value of initial antithrombin levels in neonatal sepsis.

Objectives: We determined whether initial antithrombin (AT) levels help in diagnosis and prognosis of neonatal sepsis.

Methods: Sepsis was diagnosed according to clinical and laboratory findings and positive culture results in 34 of the 54 newborns who presented to the hospital with suspected sepsis. Between AT levels and hematological parameters (fibrinogen levels, prothrombin time (PT), activated partial thromboplastin time (aPTT) and liver function tests), these were correlated each other and with outcome of the babies.

The Fc gammaRIIa polymorphism in Turkish children with asthma bronchial and allergic rhinitis.

Objective: The aim of the present study was to evaluate the Fc gammaRIIa polymorphism in Turkish children with atopic asthma and allergic rhinitis.

Design And Methods: In this study, 372 atopic children (192 asthma bronchial, 180 allergic rhinitis) between ages of 5 and 16 years old (11.3+/-2.

Effect of carbamazepine and valproate on bone mineral density.

The objective of this study was to examine the effect of carbamazepine and valproate monotherapy on bone mineral density in children. Femoral neck area bone mineral density was measured by dual-energy x-ray absorptiometry in 31 healthy children and 33 children with idiopathic epilepsy treated with either carbamazepine (n = 17) or valproate (n = 16) for more than 6 months. There were no significant differences between the control and study patients in age, height, weight, and physical activity.
