Pneumomediastinum is a rare clinical entity that concerns the clinicians in the emergency department. We present a case of a patient with spontaneous pneumomediastinum (Hamman's syndrome) that presented to our hospital's emergency department with cervical subcutaneous emphysema. A conservative treatment with observation was performed. The patient after 24 hours of observation was discharged with a suggested follow-up.
Background
Low cardiorespiratory fitness (CRF) is associated with the development of cardiovascular diseases during childhood, adolescence and older ages. The purpose of the study was to investigate associations between fatness, hemodynamic characteristics and secondary time with CRF in primary school-aged children.
Methods
Height, weight, body mass index (BMI), blood pressure (BP), heart rate (HR), CRF (20 m shuttle-run) and sedentary time were measured for 105 children (categorized as normal, overweight, obese). The independent sample t-test checked for differences and one-way ANOVA—Post Hoc Test and stepwise linear regression analysis assessed the 20 m shuttle-run performance predictors.
Results
There was a statistically significant difference in CRF between boys and girls. There was a statistically significant difference between (p < 0.05) CRF for Normal weight (M = 47.58 ± 3.26 kg m−2) and Obese (M = 44.78 ± 3.23 kg m−2). CRF correlated with age, BMI and sedentary time (r > 0.3; p < 0.05). BMI is the best independent predictor of CRF.
Conclusions
Children with normal BMI tend to present better CRF performance than obese and overweight children. Sedentary behaviour is associated with lower CRF in primary school-aged children.
Adenosine test appears to be at least comparable with CSNRT in making the diagnosis of SSS and may be considered as an alternative non-invasive test for confirmation of suspected SSS. No difference in the susceptibility of AVN to adenosine between the pts with syncope in the presence of SSS and those with unexplained syncope was found, suggesting that adenosine test cannot be used to diagnose atrioventricular block as the cause of syncope.
We report a case of ST elevation in right precordial leads compatible with type 1 Brugada syndrome following administration of propafenone in a patient with Wolff-Parkinson-White syndrome who was receiving lithium at concentrations within therapeutic levels. The mechanism of the electrocardiogram changes was considered to be caused by the two drugs synergistic sodium channel blocking effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
