RESUMO
Approximately 30-50 percent of individuals with natural rubber latex (NRL) allergy show an associated hypersensitivity to particular plant-derived foods, which has been defined "latex-fruit syndrome" (LFS). In our population of 22 patients with IgE-mediated NRL allergy we found a relevant prevalence (36 percent) of LFS, which resulted significantly higher in the group of patients with more severe clinical manifestations of NRL allergy than in patients with contact symptoms due to NRL (78 percent vs 8 percent; less than 0.005).

There are few data in the literature reporting the evolution of hypogammaglobulinemia in premature and full-term infants during the first years of life. The aim of this study was to assess the clinical and immunological evolution of premature and full-term infants with hypogammaglobulinemia. We included 24 children (11 premature and 13 full-term infants), aged 0-36 months, with hypogammaglobulinemia. Fifteen (62.5%) children had an isolated reduction in IgG, 7 (29.2%) had a decrease in both IgG and IgA and 2 (8.3%) a reduction in IgG and IgM. Normalization of IgG serum levels occurred in the premature infants at a mean age of 7.2 months. Full-term infants were divided into 3 groups based on age at normalization of IgG serum level: A) hypogammaglobulinemia with normalization within 12 months of life; B) with normalization within 36 months of life; C) normalization after 36 months. All the premature infants with hypogammaglobulinemia recovered, even though in the lower limits for age in the first years, while transient hypogammaglobulinemia observed in full-term infants has a different age of recovery.

We tested the performance of a XeCl laser with unstable resonators using as an output coupler a phase unifying (PU) mirror, a super-Gaussian mirror, and a hard-edge mirror. The quantitative impact of the output coupler design on the energy extraction efficiency, near-field profile, far-field energy distribution, and spatial coherence time evolution has been investigated. Laser beams of larger brightness have been obtained with the PU unstable cavity. A faster growth of the laser beam spatial coherence has been observed with the PU cavity by time-resolved, far-field measurements.
