Peripheral adenopathies in children - an attempt of clinical morphological profile.

AIM: The authors have proposed to assess peripheral adenopathies in a series of hospitalized children in order to identify and define clinical and morphological profiles of different types of lymph node (LN) diseases. MATERIALS AND METHODS: The studied group consisted of 58 patients less than 18 years of age. The investigation algorithm included: gender, age, site, involvement, side, extension and histopathological (HP) type of LN lesions. Tissue fragments were processed using classical histological techniques (formalin fixation and paraffin embedment) and stained with Hematoxylin-Eosin (HE). In some cases (tuberculous lesions and lymphomas), special stainings (Ziehl-Neelsen) and immunohistochemistry were used. Stratification scales of cases were defined according to each parameter in order to compare the data. All obtained data were assessed individually, compared to each other and with similar data from the literature with the help of a statistical apparatus [χ² (chi-squared) test and analysis of variance (ANOVA) test] in some cases. RESULTS: The young patients were slightly more frequently boys, of all ages but with a mean age of 10 and half years. The affected LNs belonged most often to neck region, either on the left or on the right side but sometimes bilateral or even on the midline; usually, more than one LN was involved in the area. In most of the cases, the lesions were localized in only one LN area. HP picture was dominated by the inflammatory processes, firstly the nonspecific ones, followed by tuberculosis. DISCUSSIONS: Our observations fitted, for each parameter, with the wide ranges found in the literature. Comparisons between parameters' variations revealed differences, sometimes significant that we tried to organize in clinical and morphological profiles. CONCLUSIONS: The assessment of our data allowed us to define some clinical and morphological profiles of different types of adenopathy that, by improvement on studies including larger series, could be of real use in daily pediatric practice.

Clinico-pathological study of chronic rhinitis in adolescents.

Through the increasing incidence and association of asthma, chronic rhinitis (CR) raises major problems in the pathology of children and adolescents. The evaluation of the inflammatory status together with the diagnosis and the tandem treatment of the two conditions can contribute to the improvement of the patients' quality of life. In this study, we analyzed the immunoexpression of cluster of differentiation (CD) 20, CD8, CD138 and eosinophil major basic protein (MBP) in 24 cases of CR in adolescents, in eight of them existing the association of asthma. Symptoms of CR and allergic status, as well as histopathological changes specific to a persistent inflammation, were identified in this study. The CD20∕CD8 immunophenotype was more specific for CR, while the CD138∕eosinophil MBP immunophenotype was specific for asthma-associated chronic rhinitis (AACR). The negative linear distribution of lymphocyte elements compared to plasmocytes and eosinophils specific for the allergic status can support the protective effect of CD8 T-lymphocytes and the presence of a semi-activated B-lymphocyte status in CR. The results may be useful for improving the stratification criteria of patients for therapy.
