RESUMO
Introduction: Most infants at risk for cytomegalovirus (CMV)-associated sensorineural hearing loss (SNHL) are unrecognized because of the absence of a universal neonatal CMV screening. The search of CMV-DNA by molecular methods in salivary swabs was demonstrated to be a reliable approach. This study describes the results obtained by carrying out a universal screening for congenital CMV (cCMV) infection including all live-born newborns in three Italian sites, as well as the therapeutic interventions and clinical outcome of the CMV-infected neonates. Moreover, CMV maternal infection's characteristics were evaluated. Methods: To confirm or exclude cCMV infection, a CMV-DNA-positive result on a first salivary swab was followed by repeated saliva and urine samples collected within 21 days of age. Breast milk samples were also collected. The search of CMV-DNA was performed with a single automated quantitative commercial real-time PCR assay, regardless of the type of samples used. Results: A total of 3,151 newborns were enrolled; 21 (0.66%) of them were congenitally infected (median saliva viral load at screening, 6.65 [range, 5.03-7.17] log10 IU/ml). Very low/low viral load in screening saliva samples (median value, 1.87 [range, 1.14-2.59] log10 IU/ml) was associated with false-positive results (n = 54; 1.7%). CMV-DNA was detected in almost half of the breast milk samples of mother-infant pairs with a false-positive result, suggesting that contamination from breast milk may not be the only explanation in the study population. cCMV infection confirmation with the search of CMV-DNA in a urine sample proved to be the gold standard strategy, since false-positive results were observed in 4/54 (7.5%) of the repeated saliva samples. Symptomatic cCMV infection was observed in 3/21 (14.3%) infants; notably, one (4.7%) developed moderate unilateral SNHL at 5 months after birth. Finally, two symptomatic cCMV infections were associated with primary maternal infection acquired in the first trimester of gestation; one newborn with severe cCMV symptoms was born to a mother with no CMV checkups in pregnancy. Conclusion: Without universal neonatal CMV screening, some infected infants who develop late neurological sequelae may not be recognized and, consequently, they are not able to benefit early from instrumental and therapeutic interventions to limit and/or treat CMV disease.
RESUMO
We present the case of a child who initially presented with gastrointestinal symptoms suggestive of severe rotavirus gastroenteritis complicated by hyponatraemic dehydration. Appropriate intravenous fluid therapy was administered but the patient, still feverish, developed anasarca probably due to hyperpermeability of microvessels following massive inflammation. Atypical Kawasaki disease was diagnosed on the basis of the clinical findings and laboratory tests. An echocardiogram performed on the 14th day showed a coronary artery aneurysm of the right coronary artery and a generalised dilation of left coronary artery without pericardial effusion. Anasarca in Kawasaki disease has never been reported before in the literature. A rotavirus infection probably triggered the severe and atypical signs in the case reported here.
RESUMO
To examine whether long-term consumption of fermented milk containing a specific Lactobacillus casei may improve the health status of preschool children suffering from allergic asthma and/or rhinitis a randomized, prospective, double blind, controlled trial was conducted in 187 children 2-5 y of age. The children received for 12 mo either fermented milk (100 mL) containing Lactobacillus casei (10(8) cfu/mL) or placebo. The time free from and the number of episodes of asthma/rhinitis after starting intervention were the outcome measures. The number of fever or diarrhea episodes and the change in serum immunoglobulin were further assessed. No statistical difference between intervention and control group occurred in asthmatic children. In children with rhinitis, the annual number of rhinitis episodes was lower in the intervention group, mean difference (95% CI), -1.6 (-3.15 to -0.05); the mean duration of an episode of diarrhea was lower in the intervention group, mean difference -0.81 (-1.52 to -0.10) days. While long-term consumption of fermented milk containing Lactobacillus casei may improve the health status of children with allergic rhinitis no effect was found in asthmatic children.
