[Contribution of indicators of sensitized T lymphocytes in the diagnosis of IgE independent and IgE dependent cow's allergy in children].

Background: Food allergy is an abnormal response of the immunological system, especially of mucosal immunological system on antigens supplied per os. There are very complicated and still unexplained immunological mechanisms, which lead to hypersensitivity reaction. Most often food hypersensitivity is identified as the effect of atopy, which is connected with humoral response (specific IgE antibody).

[Limulus amebocyte lysate test use in clinical diagnostic in children with infectious diseases--preliminary report].

Objective: The aim of this preliminary study was (1) to evaluate the usefulness of the Limulus amebocyte lysate (LAL) test as a diagnostic tool in pediatric clinic, and (2) to examine the serum ET levels in hospitalized patients.

Material And Methods: Bacterial blood endotoxin (ET) was measured in 50 children with infections of different etiology and localization. A Limulus amebocyte lysate (LAL) test was used.

[Bartter's syndrome].

Bartter syndrome is an uncommon tubular disorder inherited as an autosomal recessive entity. It is associated with hypokalemic metabolic alkalosis with high renin and aldosterone plasma concentration with low or normal blood pressure. Recent studies have demonstrated genetic heterogeneity in Bartter syndrome.

[Gastroesophagopharyngeal reflux in infants and children with recurrent symptoms of the upper respiratory tract].

Gastroesophageal reflux (GER) plays an important role in pathogenesis of recurrent/chronic disorders of the respiratory tract. Atypical symptoms of GER can be suggested to be cause of the otorhinolaryngological problems. For these last manifestations no cause-effect relationship has yet been proven.

[Long-term clinical observation of infants with gastroesophageal reflux].

The aim of the study was long-term observation of patients with gastroesophageal reflux (GER), diagnosed in their infancy, in aspect of spontaneous resolution of this disorder. 290 symptomatic infants aged 5 weeks to 11 months (mean--5.8 months) underwent 24-hour esophageal pH monitoring.

[Alkaptonuria: a rare metabolic disorder. A report of two cases in siblings].

Alkaptonuria is a rare metabolic condition caused by congenital homogentisate oxidase deficiency of recessive inheritance. Homogentisate polymers are accumulated and cause urine darkening, brown pigmentation of connective tissue, articular cartilage pathology. The authors present clinical picture, pathogenesis, diagnostic and therapeutic possibilities in patients with alkaptonuria.

[Dual simultaneous esophageal pH monitoring in infants with gastroesophageal reflux].

The aim of the current study was to analyse selected parameters of pH monitoring in the proximal and distal parts of esophagus. One hundred and twelve infants aged 1.25 to 18 months (mean = 5.

[The evaluation of natural anticoagulants in systemic lupus erythematosus in children].

Thromboembolic complications in adults with systemic lupus erythematosus (SLE) are described in literature. We intended to investigate the activity of natural anticoagulants, such as C protein. S protein and antithrombin III (AT III) in children with SLE to obtain data concerning activity of the disease and thrombotic complications.
