The aim of the study was estimation of the IgE value, circulating immunocomplexes and the activity of complement system in allergic contact as well as atopic dermatitis in patients with skin nickel hypersensitivity. The study was done in 30 patients in the age range of 18-53 yrs suffering from allergic contact dermatitis (15 patients) and atopic dermatitis (15 patients) with positive skin patch test to nickel. ⋯ The results of the study indicated an increase of concentration of circulating immuno-complexes in 80% of the patients of both groups, an increase of total IgE in 50% of patients with atopic dermatitis and in 25% of the patients with contact dermatitis. There were no changes in the activity of C1inh and the value of CH50 in both groups of patients.

Comparative Study
[The role of transesophageal echocardiography (TEE) in assessment of left ventricular tract obstruction].
Twelve children with subaortic stenosis were analysed. Nine of them developed left ventricular outflow obstruction after surgery for congenital heart disease (VSD + IAA, VSD + DORV, VSD + TGA, VSD + CoA) and then developed an isolated form of primary stenosis. ⋯ TTE was sufficient to assess isolated subaortic stenosis. In children after cardiosurgery, TEE was more reliable and provided more detailed visualisation of the stenosis and its relationship to surrounding structures.

Abnormalities of autonomic nervous system function (ANS) exist in patients with hypertension and have been considered as one of the important factors in developing of essential hypertension. However the information about the effect of antihypertensive treatment (angiotensin-converting enzyme inhibitors--ACEI) on cardiac ANS activity is scarce. The main aim of our study was to evaluate circadian heart rate variability changes in primary hypertension treated with ACE inhibitors. ⋯ Our observations support an attenuation of night vagal activity as an important factor in the pathogenesis of essential hypertension. The lack of effect of ACEI treatment on circadian heart rate variability parameters in patients with essential hypertension, despite long-term normalisation of blood pressure, suggests persistent circadian cardiac autonomic dysfunction in the "dippers" subgroup of patients.

Systemic bacterial infections still remain one of the major causes of neonatal morbidity and mortality. Early detection of neonatal sepsis can be difficult, because the first signs of the disease may be unspecific and similar to symptoms of other non-infectious processes. Procalcitonin became a new, sensitive marker of bacterial infections in newborns. The aim of our study was to assess the value of PCT as a diagnostic and prognostic tool of neonatal maternofetal infections. We also tried to estimate normal ranges of PCT in uninfected newborns. ⋯ PCT is a useful tool in early diagnosing and monitoring the course of early-onset infections in neonates, particularly when blood cultures obtained from neonates remain negative. The decreasing concentrations of PCT level in children treated due to infection, indicate successful treatment and may help one to take a decision on termination of antibiotic therapy.
