The aim of this study was to investigate differences in airway inflammation between childhood and adult-onset asthma. A total of 47 asthmatic subjects were recruited from patients attending outpatient clinic. A group of 32 adults, mean age 42.8 years (yrs) and a group of 15 children, mean age 11.7 yrs were included. The two groups did not differ in respect to gender, dose of inhaled corticosteroids, atopy status or duration of asthma (mean duration 7.75 yr). Lung function tests, and sputum induction were performed. Flowcytometry was used to study cell population and interleukin-8, eosinophilic cationic protein (ECP) and granulocyte-macrophage colony stimulating factor were measured by enzyme-linked immunosorbent assay (ELISA). Three out of 15 (20%) of the children and 6 out of 32 (19%) of the adult patients were unable to produce a sufficient sputum sample. However, all individuals tolerated the procedure well. The viability of induced sputum cells did not differ among adult-onset asthmatics and children with asthma. Children had greater number of total cells in induced sputum compared with adult subjects (P ¼ 0:02). No statistical difference in T-lymphocytes subsets was found between the two groups, except for CD25 (P ¼ 0:04). A negative correlation was found between forced expiratory volume (FEV 1) values and ECP levels (r ¼ 0:338, P ¼ 0:04) in the whole population (children and adults).

Cervical lymphadenopathy (CL) is common in childhood. The aim of this study is to evaluate the etiology, follow-up, and treatment of persistent CL. The authors studied retrospectively 50 children with CL, hospitalized at the Department of Pediatrics and Pediatrics Surgery. Patients underwent ultrasonography. Thirty-six percent presented abnormal ultrasonographic image and underwent excisional biopsy. Biopsies revealed 4 thyroglossal cysts, 3 branchial cysts, 1 hemangioma, 2 sebaceous cysts, 1 dermoid cyst, 5 occurrences of tuberculosis lymphadenitis, 1 occurrence of Bartonella henselae lymphadenopathy, and 1 case of non-Hodgkin lymphoma. In conclusion, CL is usually a benign finding; bacterial and viral infections are the most common causes. Ultrasonography help in etiology and follow-up of CL.
