RESUMO
Since March 2020, the world is involved in the COVID-19 pandemic, a disease caused by a novel virus called SARS-CoV-2. Some authors have described the ultrasonographic findings of COVID-19 pneumonia in adults and children, but data on neonates are lacking. Our objective was to describe the ultrasonographic lung pattern on newborns with SARS-CoV-2 infection during the COVID-19 pandemic. Newborns who tested positive for SARS-CoV-2 PCR in respiratory samples and were evaluated with point-of-care lung ultrasound (LU) from March to April 2020 were included. LU was performed bedside by a single investigator at the time of diagnosis and every 48 h during the first week following diagnosis. Six areas were studied. Three neonates were included. Infants' comorbidities included meconium aspiration syndrome, bronchopulmonary dysplasia, and Hirschsprung's disease. One required mechanical ventilation. No deaths occurred. LU showed B-lines, consolidation, and spared areas. No pneumothorax or pleural effusion was observedConclusions: LU could be of value when managing COVID-19 neonates. We describe the findings of lung ultrasound monitoring during the first week following diagnosis in three neonates with SARS-CoV-2 infection. What is known: ⢠Lung ultrasound (LU) is a useful tool in COVID-19 management in adults. To date, no report on LU and neonates with SARS-CoV-2 infection has been published. What is new: ⢠This study adds evidence about LU findings in neonates with SARS-CoV-2 infection.

BACKGROUND: The prevalence of atopic dermatitis (AD), a chronic skin disease, has increased substantially in recent decades, and different factors have been implicated in its etiology. Although dietary habits are being investigated, few conclusive findings have been reported. Nevertheless, increased consumption of polyunsaturated fatty acids (PUFA) and a diet poor in antioxidants have been related to AD. OBJECTIVES: The objectives of this study were to investigate the association between AD, the intake of different foods, and the effect of a Mediterranean diet among Spanish schoolchildren aged 6 to 7. METHODS: We performed a cross-sectional study with 20 106 schoolchildren aged 6-7 years from 10 different areas of Spain. The participation rate was 76.50%. The prevalence of AD was assessed using the International Study of Asthma and Allergies in Childhood questionnaire and the criteria of the Spanish Academy of Dermatology. To calculate the Mediterranean diet score, we classified food into 2 groups: Mediterranean food, including fruit, seafood, vegetables, pulses, cereals, pasta, rice, and potatoes; and non-Mediterranean food, including meat, milk, and fast food. RESULTS: Milk was negatively associated with AD. Butter and nuts also were negatively associated, although statistical significance was only reached when these foods were consumed 3 or more times a week. CONCLUSIONS: We found no association between the Mediterranean diet score and AD and a positive association between AD and obesity.

Some myths and unsupported beliefs about asthma are very popular and enjoy general public acceptance and fairly strong support on the Internet. Onions for cough; dairy products avoidance for asthma; and some other popular myths are reviewed, along with some other medical and mixed (popular and medical) myths comparing their popular and scientific support. Classifying medical statements as realities or unsupported beliefs is a hard and serious work nowadays addressed by Evidence Based Medicine methods, which are not devoid of the influence of medical fashion: the medical community is more prone to accept fashionable statements compared to non-fashionable or old-fashioned statements.

BACKGROUND: Questionnaires are widely used in epidemiological studies to measure eczema symptom prevalence, but there are concerns regarding their accuracy if used as a diagnostic tool. OBJECTIVES: To compare the performance of a validated eczema symptom questionnaire and a standardized skin examination protocol employed in the second phase of the International Study of Asthma and Allergies in Childhood (ISAAC). METHODS: A total of 30,358 schoolchildren aged 8-12 years from 18 countries were examined for flexural eczema. Parents also completed an eczema symptom questionnaire. We compared prevalence estimates at the population level based on the questionnaire vs. physical examination. We also compared the skin examination and the ISAAC questionnaire in making a diagnosis of flexural eczema. RESULTS: The point prevalences for flexural eczema at centre level based on a single examination were lower than the questionnaire-based 12-month period prevalences (mean centre prevalence 3.9% vs. 9.4%). Correlation between prevalences of both outcome measures was high (r = 0.77, P < 0.001). At the individual level, questionnaire-derived symptoms of 'persistent flexural eczema in the past 12 months' missed < 10% of cases of flexural eczema detected on physical examination. However, between 33% and 100% of questionnaire-based symptoms of 'persistent flexural eczema in the past 12 months' were not confirmed on examination. CONCLUSIONS: ISAAC questionnaire-derived symptom prevalences are sufficiently precise for comparisons between populations. Where diagnostic precision at the individual level is important, questionnaires should be validated and potentially modified in those populations beforehand, or a standardized skin examination protocol should be used.

Background and aims: Atopic eczema (AE) is the most frequent inflammatory skin disease in childhood in the western world. Several studies have reported a significant increase of prevalence in recent decades and the environmental factors implicatedin its a etiology, including environmental tobacco smoke.This study aims to investigate the possible association of AE prevalence in Spanish school children aged 6-7 and 13-14 years in relation to their parentssmoking habits. Methods: We conducted a cross-sectional population-based study with 6-7 year-old (n = 27805) and 13-14 year-old (n = 31235) school children from10 Spanish centres. AE prevalence was assessed using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire, and the Spanish Academy of Dermatology criteria, used in Spain to diagnose AE. Results: An association was found in school children aged 6-7 (adjusted for gender, presence of asthma, presence of rhinitis, siblings and mothers level of education) between AE being clinically diagnosed with the mothers smoking habit (RPRa 1.40,1.10-1.78) and there being more than 2 smokers at home (RPRa 1.34, 1.01-1.78). Regarding the presence of itchy rash, an association was observed with fathers who smoke (RPRa 1.40, 1.13-1.72). Among the 13-14 year-olds, no association was observed in relation to either clinically diagnosed AE or the appearance of itchy rash with parents smoking habit. Conclusions: Our results indicate the risk for children of being exposed to environmental tobacco smoke in terms of AE, especially when they are younger

OBJECTIVE: This study aimed to evaluate the adverse effects of extensively hydrolyzed milk formula on growth in infants and toddlers. METHODS: Prospectively, 45 infants and toddlers with a positive history of cow's milk allergy confirmed by positive skin prick test and high IgE levels for either alpha-lactalbumin, beta-lactoglobulin, or casein and positive single-blind food challenge received extensively hydrolyzed milk formulas for 1 year. Sex-normalized percentiles of heights and weights of infants and toddlers before their enrollment in the study were compared to those at the end of the study. The contribution of breastfeeding, early use of bottle feeding and intake of adapted or special milk formulas, and history of bronchitis and atopic dermatitis on toddlers' growth were also evaluated by multivariate analysis. RESULTS: Similar percentiles of the children's weight and height were observed at the beginning of the study and 1 year later. According to the multivariate analysis, sex, breastfeeding, early bottle feeding, ingestion of adapted or special milk formulas, atopic dermatitis, and bronchitis were not correlated with either the children's weight or height at diagnosis of the allergy or at 1 year of follow-up (P > .10). Weights and heights were not different between toddlers who had atopic dermatitis or bronchitis during the study period and those who did not. CONCLUSIONS: Growth of infants and toddlers with cow's milk allergy was not affected by the intake of extensively hydrolyzed milk for 1 year. Atopic dermatitis and bronchitis did not appear to have any deleterious effect on these children's growth.

INTRODUCTION: Approximately 2-3 % of infants develop cow's milk allergy (CMA). Treatment consists of eliminating milk from the diet. Some studies have shown growth failure in children with CMA and a milk-free diet. OBJECTIVES: To evaluate growth status at 1 and 2 years of age in infants diagnosed with CMA. MATERIAL AND METHODS: An observational, longitudinal, retrospective study of all infants diagnosed with CMA from 2000-2001 was performed. The following data were analyzed: chronology and type of feeding, the presence of allergy to other foods, atopic dermatitis or other symptoms of allergy, duration of CMA, and anthropometric data (weight and height) at diagnosis, and at 1 and 2 years of age. Anthropometric data were expressed as Z-scores. RESULTS: A total of 141 infants (71 boys and 70 girls) were studied. Atopic dermatitis was found in 67 infants (47.5%) and wheezing in 36 (25.5%). Allergy to foods other than milk was found in 27%. Only 21.3% of the infants grew out of CMA at the age of 2 years, of which 37% did so in the first year of life. Z-scores for weight were -0.5 at birth, -0.25 at the first follow-up visit, -0.25 at 1 year, and -0.19 at 2 years. Z-scores for height were 10.26 at the first follow-up visit, 10.64 at 1 year, and 10.35 at 2 years. A significant difference in Z scores for weight was found in infants with allergies to other foods, atopic dermatitis or wheezing compared with those with CMA only. CONCLUSIONS: Infants with CMA receiving a substitute formula (hydrolyzed or soy formulae) showed normal weight and height at 2 years, although the percentile for height tended to be better than that for weight. The presence of other food allergies, atopic dermatitis or wheezing seems to affect the nutritional status of infants with CMA.

Introducción: Aproximadamente el 2-3 % de los lactantes sufren alergia a proteínas de leche de vaca (APLV). El tratamiento consiste en su eliminación de la dieta. Algunos estudios han demostrado una disminución del crecimiento en aquellos niños con APLV y dieta exenta en lácteos. Objetivos: Evaluación del crecimiento al año y a los 2 años de edad de una cohorte amplia de lactantes diagnosticados de APLV. Material y métodos: Estudio observacional, longitudinal y retrospectivo de todos los lactantes diagnosticados de APLV en el período 2000-2001. Se recogieron datos relativos a la cronología y tipo de alimentación, presencia de alergia a otros alimentos, dermatitis atópica u otros síntomas de alergia, duración de la APLV y datos antropométricos (peso y talla) en el momento del diagnóstico, al año y 2 años de edad. Los datos antropométricos se expresan como puntuación Z. Resultados: Fueron diagnosticados de APLV 141 niños (71 niños y 70 niñas). Un total de 67 niños (47,5 %) presentaron dermatitis atópica y 36 (25,5 %) sibilancias. El 27 % tuvo alergia a otros alimentos además de la leche. Sólo el 21,3 % de los niños habían superado la APLV a los 2 años de edad, de los que el 37 % lo hicieron en el primer año. La puntuación Z para el peso fue 0,5 al nacimiento, 0,25 en la primera visita; 0,25 al año y 0,19 a los 2 años. La puntuación Z para la talla fue de 10,26, 10,64 y 10,35 en el momento del diagnóstico, al año y a los 2 años de edad, respectivamente. La alergia a otros alimentos, la presencia de dermatitis atópica o de sibilancias resultaron en una diferencia significativa de la puntuación Z del peso con respecto a los que sólo presentaron alergia a APLV. Conclusiones: Los niños con APLV que toman una fórmula de sustitución (hidrolizado o preparado de soja) tienen, a los 2 años de edad, un desarrollo ponderoestatural similar al de la población sana, aunque se apreció una tendencia a mejor percentil de talla que de peso. La multialergia alimentaria, así como la presencia de dermatitis o sibilancias, parecen ser factores que afecten al estado nutricional del niño con APLV

A tracheostomy was performed in a 4-month-old girl with Crouzon's syndrome because of upper respiratory obstruction. During the procedure the absence of tracheal rings was observed. These findings were confirmed by postoperative bronchoscopy. Subsequent surgical correction of the patient's craniofacial anomalies enabled decannulation when the patient was 10 months old. Complete cartilaginous trachea is very rare and is always associated with craniosynostotic syndromes. Tracheobronchial anomalies should be investigated in patients whose respiratory symptoms are not due to upper airway obstruction.

The difference between exudates and transudates is the first question a clinician must solve when facing a pleural effusion. A great number of parameters have been tried without a definite efficacy of any of them. Cholesterol is an easy, useful determination for distinguishing exudates from transudates. In our series of 86 patients a cholesterol value of 50 mg/dl allowed us to correctly classify 94.2% of effusions. The ratio between pleural fluid cholesterol/serum cholesterol was more efficient because it permitted to correctly classify 97.7% of effusions, in one of those major groups which constitute the binomial exudate/transudate.
