6 times greater than among non-Hispanic infants of similar age.

Conclusions: Ensuring pertussis booster vaccination of adults and adolescents in close contact with an infant is warranted to prevent transmission of pertussis to vulnerable infants, particularly infants too young to be immunized. Special emphasis should be given to women and infant settings in which the risk of infant pertussis death might be increased.”
“The new semiconducting noncrystalline solid “”tellurite glasses”" of the form 0.7 TeO(2)-(0.3-x)V(2)O(5)-xA(n)O(m) have been prepared

in bulk form with different compositions where A(n)O(m) is CeO(2) or ZnO and x=0.03, 0.05, 0.07, 0.10 mol %. Longitudinal ultrasonic attenuation in these glasses has been measured at frequencies of 2, 4, 6, and 8 MHz and in the temperature range of 100-300 DMH1 K. The results showed the presence of a very well defined peak which shifts to higher temperature with increasing frequency, suggesting a

kind of relaxation process. The acoustic activation energy, as well as the relaxation frequency, has been calculated and correlated with the relaxation strength for each composition. Correlations between the present low temperature of ultrasonic attenuation and the previous room temperature elastic moduli AG-120 molecular weight have been achieved for both glass series.

“Background The epidemiology and clinical features of brachioradial pruritus are variably described in the literature. We sought to analyze these features in a large group of Brazilian patients. Patients and Methods In a descriptive, observational study, we identified all patients with a final diagnosis of brachioradial pruritus seen over a one-year period and re-trospectively reviewed their records. The diagnosis was made after clinical-laboratory investigation had ruled out other causes of chronic pruritus. Demographic and clinical variables were collected along with pruritus characteristics, and analyzed Selleck GSK1838705A using des-criptive statistics. Results Forty-three patients were identified; their mean age was 55.9 years, with predominance of women (81.4%) and Caucasians (86%). In 52%,

the pruritus worsened with heat and sun exposure; 58.1% had intermittent complaints; the ice-pack sign was present only in 20.9%. The arms involving dermatomes C5-C6-C7-C8 (62.8%) were the most affected sites, while psychoactive drugs were the most frequently prescribed therapy. Conclusions Although uncommon, brachioradial pruritus should not be neglected in dermatological diagnosis. This case series analysis indicated that Brazilian patients from a tropical climate show characteristics similar to those described in other series from more temperate regions.”
