To evaluate the effect of inhaled dexamethasone on hospitalization for respiratory syncytial virus (RSV) bronchiolitis.A double-blind, placebo-controlled study compared nebulization of dexamethasone versus nebulization of 0.9% saline. Both groups were treated with epinephrine nebulizations. Follow-up continued for 3 mo.Sixty-one infants with bronchiolitis aged 3 to 12 mo were included. They were randomly allocated to nebulizations with 0.25 mg dexamethasone every 6 h (group 1) or an equivalent amount of normal saline (group 2).No statistically significant differences with respect to clinical score, oxygen saturation, or IV fluid requirement between the groups were noted. Using Kaplan-Meyer's method, the cumulative proportion of in-hospital stay was significantly lower in group 1 compared with group 2, mainly in days 5 and 6 post-hospitalization (p0.038). A subgroup of prematurely born children in group 1 had a shorter hospitalization period (6.5+/-1.7 d) compared with group 2 children (9.1+/-1.9) (p0.018). Follow-up revealed similar wheeze and hospitalization rates in the two groups.Inhaled dexamethasone may reduce the length of hospitalization among infants with acute viral bronchiolitis, especially among those born prematurely.

The incidence rates of tuberculosis (TB) in Israel decreased steadily up to 1984, but rose again between 1985 and 1991, mainly due to immigration waves from Ethiopia. The epidemiology of TB in children was surveyed in the Ashkelon region. The regional TB register of Barzilai Medical Centre, kept since 1958, was used as the source for our data. Two hundred and fifty TB cases in children were reported between 1958 and 1994, constituting 9.7% of the total 2565 cases reported in the whole population of Israel's southern Mediterranean coast. While in the late 1950s and early 1960s the majority of reported cases occurred in children of North African origin, reflecting the large wave of immigration from North Africa at that time, in 1985-94 at the time of the Ethiopian immigration wave, Ethiopian children constituted the majority of the patients. They were diagnosed up to 9 years after arrival. None of the reported cases was HIV-positive.
