Chronic rhinosinusitis in primary antibody immunodeficient patients.

Objective: Some patients suffer from recurrent or chronic rhinosinusitis (CRS) because of previously unrecognized immunodeficiency disease. The purpose of the study was to evaluate the incidence of CRS in children with different types of primary humoral deficiency.

Study Design: Among 842 cases of primary immunodeficiency diseases diagnosed in the Department of Immunology of the Children's Memorial Institute in Warsaw from 1980 up to February 2006 antibody deficiencies occurred most frequently--in 50.

[Evaluation of the central nervous system in children with bladder dysfunction with the use of evoked potentials].

The function of the central nervous system and especially spinal cord and brainstem, were evaluated. Brainstem (BAEPs) and somatosensory evoked potentials (SEPs) were used with the stimulation of the peroneus nerve in 52 children at the age of 4.4 up to 18 years (mean age 11.
