ABSTRACT
BACKGROUND: Asthma and/or allergic rhinitis have been associated with sleep disorders. The aim of this study was to evaluate sleep disorders in Latin-American children (4-10 years) from nine countries, with persistent asthma (A) and/or allergic rhinitis (AR) and in normal controls (C). METHODS: Parents from 454 C children and 700 A and/or AR children followed up in allergy reference clinics completed the Children's Sleep Habits Questionnaire (CSHQ) which is a retrospective one-week questionnaire composed of 33 questions composed of seven subscales (bedtime resistance, sleep duration, sleep anxiety, night wakings, parasomnias, sleep-disordered breathing and daytime sleepiness). The total scale of CSHQ and the subscales were compared between groups C and A+AR, A (n=285) vs. AR (n=390), and between controlled A (CA, n=103) vs. partially controlled/uncontrolled A (UA, n=182). RESULTS: The comparison between C and A+AR showed no significant differences in age (6.7 years vs. 7.0 years, respectively), mean Body Mass Index and total scale of CSHQ (53.3 vs. 63.2, respectively) and the subscales were significantly higher in the A+AR group. Comparison between groups A and AR, except for sleep anxiety, showed significantly higher values for CSHQ total scale (66.9 vs. 61.0, respectively) and subscales for group A. The UA group showed significantly higher values for total CSHQ scale and subscales in comparison to CA (71.1 vs. 59.4, respectively). CONCLUSIONS: Latin-American children with asthma and/or allergic rhinitis showed sleep disorders identified by the CSHQ when compared to normal controls. Despite being treated, asthma causes sleep impairment, especially when uncontrolled.

BACKGROUND: Atopic dermatitis (AD) has been associated with impairment of sleep. The aim of this study was to evaluate sleep disorders in AD Latin-American children (4-10 years) from nine countries, and in normal controls (C). METHODS: Parents from 454 C and 340 AD children from referral clinics answered the Children Sleep Habits Questionnaire (CSHQ), a one-week retrospective 33 questions survey under seven items (bedtime resistance, sleep duration, sleep anxiety, night awakening, parasomnias, sleep-disordered breathing and daytime sleepiness). Total CSHQ score and items were analysed in both C and AD groups. Spearman's correlation coefficient between SCORAD (Scoring atopic dermatitis), all subscales and total CSHQ were also obtained. RESULTS: C and AD groups were similar regarding age, however, significantly higher values for total CSHQ (62.2±16.1 vs 53.3±12.7, respectively) and items were observed among AD children in comparison to C, and they were higher among those with moderate (54.8%) or severe (4.3%) AD. Except for sleep duration (r=-0.02, p=0.698), there was a significant Spearman's correlation index for bedtime resistance (0.24, p<0.0001), sleep anxiety (0.29, p<0.0001), night awakening (0.36, p<0.0001), parasomnias (0.54, p<0.0001), sleep-disordered breathing (0.42, p<0.0001), daytime sleepiness (0.26, p<0.0001) and total CSHQ (0.46, p<0.0001). AD patients had significantly higher elevated body mass index. CONCLUSION: Latin-American children with AD have sleep disorders despite treatment, and those with moderate to severe forms had marked changes in CSHQ.

We report the complete genome sequence of the first Mexican human coronavirus (HCoV) OC43, obtained by new-generation sequencing and a metagenomic approach, isolated from a child hospitalized with pneumonia. The genome is closely related to the other OC43 genome sequences available, ranging from 99.8% to 98.2% nucleotide sequence identity.
ABSTRACT
Presenta estudio formativo para el desarrollo de estrategias de comunicación para fomentar la vacunación sistemática en Nicaragua. El estudio se realizó mediante metodología cualitatiava. Se realizaron 16 grupos focales con madres y 3 con padres; 46 entrevistas a profundidad con personal de salud y 9 con brigadistas; 109 entrevista de salida. La población de estudio fueron: a) madres y padres de niños menores de dos años; b)personal de salud ligado al PAI: responsable del programa en los SILAIS, médicos, enfermeras y auxiliares de enfermería; c)brigadistas de salud. El área de estudio corresponde a ocho SILAIS, tomados de las cinco regiones geográficas en que se divide el país: Nueva Segovia, Madriz, León, Managua, Matagalpa, Chontales, Rivas y la Región Autónoma del Atlántico Sur. Se discutieron en tres talleres de validación, que se efectuaron en Somoto, Matagalpa y Managua

The aim of this work was to measure oxygen consumption and carbon dioxide production during exercise in 21 subjects with cardiac failure and 13 normal subjects. During the resting period, subjects with cardiac failure had higher ventilatory frequency and respiratory quotient than normals. During maximal exercise, the former achieved higher ventilatory frequency and oxygen ventilatory equivalent than normals. In subjects with cardiac failure and normals, anaerobic thresholds were 14.4 +/- 0.9 and 28.8 +/- 2.2 ml/kg/min respectively and peak oxygen consumptions 17.1 +/- 1 and 34.4 +/- 1.7 ml/kg/min respectively. There were less than 10% differences in parameters when tests were repeated in 10 subjects with cardiac failure. It is concluded that gas exchange testing may be a reliable and objective assessment method in patients with cardiac failure.

Pneumocystis carinii pneumonia is frequent in patients with cellular immunity impairments, specially those with AIDS. We communicate our experience in 20 patients (15 with AIDS) with Pneumocystis carinii pneumonia confirmed by the finding of trophozoites or cysts. Clinical manifestations were cough in 75% of cases, dyspnea in 70% and fever in 65%. Eighty five percent of cases had diffuse reticular and nodular radiological densities. Nineteen patients had an increased alveolar-arterial O2 gradient. Nineteen patients were treated with trimethropim-sulphamethoxazole (TMP-SMX) and 4 with pentamidine isethionate (1 due to previous allergy and 3 due to poor response to TMP-SMX). Three patients died during the acute episode. Of the survivors, 13 died within 2 to 44 months later (14.5 +/- 12 months). It is concluded that AIDS is the most frequent underlying condition in patients with Pneumocysts carinii pneumonia and that long term survival is low.
