Evaluation of allergic sensitization and gastroesophageal reflux disease in children with recurrent croup.

Background: Croup, which is seen commonly in childhood, is a disorder that can be recurrent and progress to bronchial asthma. In the present study the prevalence of gastroesophageal reflux (GER) and atopy and the response to therapy were investigated in children with recurrent croup.

Methods: Between October 2003 and June 2004, 57 patients with acute stridor were admitted to the emergency room.

Superior herniation of the thymus into the neck--a familial pattern.

Superior herniation of normal mediastinal thymus into the anterior neck is a rare cause of neck masses in children. It is defined as intermittent migration of the broadest part of the normal thymus out of the thorax into the suprasternal region during Valsalva maneuver with an increase in the intrathoracic pressure. The fact that the mass apparent only during Valsalva maneuver and typical ultrasound characteristics usually allow the diagnosis but computerized tomography scan or magnetic resonance imaging is necessary to assess the extent of the mass.

Diagnosing iron deficiency in cyanotic heart disease.

Objective: To determine the incidence of iron deficiency in children with CCHD by noninvasive, inexpensive and easy laboratory methods.

Methods: Forty four children with cyanotic congenital heart disease (CCHD), aged 6 to 48 months were included in this study. The patients were categorized as iron deficient (n:28) and iron sufficient group (n:16).
