ABSTRACT
INTRODUCTION AND IMPORTANCE: Sternutation is, by definition, a situation that increases abdominal pressure. However, it has not been clearly linked to protrusion of abdominal content through weaknesses in the abdominal boundaries. CASE PRESENTATION: Here we present a case report in which the only trigger factor found for an abdominal content protrusion was a sternutation episode. The patient arrived in our institution with the diagnosis of a transdiaphragmatic intercostal hernia, proven in CT-scan. He was, then, submitted to emergent surgery, where through thoracotomy and subcostal laparotomy, hernia content was reduced. The patient had a favorable evolution. CLINICAL DISCUSSION: TDIH is a rare entity, for which there are still no consensus regarding its management. This makes clinical practice more challenging, leaving to the surgeon the therapeutic decision tailored to each patient. CONCLUSION: This entity should be further studied, and consensus reached regarding its management.
ABSTRACT
AIM: To evaluate the association between the indoor air quality in Porto schools and the prevalence of allergic and respiratory symptoms in adolescents. MATERIAL AND METHODS: Temperature, relative humidity, carbon dioxide (CO2) and volatile organic compound (VOC) concentrations were evaluated in nine Porto schools. Questionnaires were distributed to 9 classes of 7th , 8th and 9th year students in each school, total 1607 adolescents, with a mean age of 14.0 years (standard deviation=0.3). Information was collected on participants' socio-demographic and social characteristics, behaviour, and housing conditions. The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was used to evaluate respiratory symptoms. RESULTS: 5.8% of participants stated they had had asthma, 9.2% wheezing, 22.0% sneezing and 6.6% itchy rash In the 12 months preceding the evaluation. After adjustment for parental educational attainment level, CO2 > 2100 ppm values were associated with exercise- induced wheeze [OR=1.86 (95%CI:1.20-2.89)] and night cough [OR=1.40 (4.20-2.89)]. We observed an increasing odds ratio in wheezing symptoms over the last 12 months, in asthma 'at some point' and asthma over the last 12 months, and night cough at schools with higher VOC values. The association was not statistically significant, however. CONCLUSION: Lower indicators of indoor air quality, particularly CO2, were associated with a greater respiratory symptomatology.
