[Assessment of the natural history and clinical presentation of acetonemic vomiting].

Introduction: Ketosis in children may result from physiological adaptation to situations like fasting, fat-rich diet, straining physical activity, as well as from serious endocrine or metabolic disorders. The most frequently diagnosed cause of ketoacidosis are states of acetonemia and acetonuria with vomiting, during airways infections.

Goal: Assessment of the natural history and clinical presentation of acetonemic vomiting in children.

Serum TARC and CTACK concentrations in children with atopic dermatitis, allergic asthma, and urticaria.

Background:   Thymus and activation-regulated chemokine (TARC/CCL17) and cutaneous T cell-attracting chemokine (CTACK/CCL27) belong to the CC chemokine family, which plays an important role in immune-inflammatory processes. It has been demonstrated that serum concentrations of TARC and CTACK are increased in patients with various allergic diseases.

Aim:   To compare serum TARC and CTACK concentrations between children with different clinical manifestation of mast cell-dependent diseases, such as atopic allergy and urticaria.

Cytokine production by peripheral blood CD4+ and CD8+ T cells in atopic childhood asthma.

There are conflicting studies on T cell cytokine production in childhood asthma. In this study intracellular cytokine expression of IL-2, IL-4, IL-10, IL-13, IFN-γ, and TNF-α in CD4(+) and CD8(+) T cells in children with atopic asthma were measured by flow cytometry. Results.

[Periodic fever, aphtosus stomatitis, pharyngitis, cervical adenopathy syndrome (PFAPA syndrome) in 4-years old girl--case report].

Characteristic feature of PFAPA syndrome is periodic episodes of fever recurring in 21-28 days in infants and young children. Fever is accompanied by aphtosus stomatitis, pharyngitis and cervical adenopathy. Diagnosis of this syndrome are based on typical clinical manifestations, because there are no characteristic changes in laboratory findings.

Ultrasound picture of gastroesophageal junction in children with reflux disease.

The assessment of gastroesophageal junction morphology is very important in children with reflux disease. Authors present ultrasonographic measurements of subdiaphragmatic part of the esophagus and His angle. In children with reflux disease, marked shortening of subdiaphragmatic part of esophagus and completely obtuse His angle were found.
