Effect of Threshold Inspiratory Muscle Training on Functional Fitness and Respiratory Muscle Strength Compared to Incentive Spirometry in Children and Adolescents With Obesity: A Randomized Controlled Trial.

Background: To determine the effect of threshold inspiratory muscle training (IMT) on functional fitness and respiratory muscle strength (RMS) compared to incentive spirometry (IS) in children/adolescents with obesity.

Methods: A total of 60 obese children/adolescents aged 8-15 years were randomized into the threshold IMT group ( = 20), the IS group ( = 20), or the control group ( = 20). The IMT group performed 30 inspiratory breaths with the intensity set at 40% of baseline maximal inspiratory pressure (MIP) twice daily for 8 weeks; the IS group performed 30 breaths with sustained maximum inspiration twice daily for 8 weeks; and, the control group was assigned no training device for 8 weeks.

A rare case of mediastinal lymphatic venous malformations in children.

We report a case of mediastinal lymphatic venous malformations (LVM) in a 11-year-old boy who presented with chest pain after jumping into a swimming pool, with review of the literature. A superior mediastinal mass was incidentally found from the chest x-ray. Chest computed tomography revealed a large heterogenous mass at the left-sided mediastinum containing fat, minimal enhancing solid portion, non-enhancing cystic portion and calcification.

Paediatric haemoptysis from multiple pulmonary artery aneurysms.

The case of multiple peripheral pulmonary artery aneurysms in children presenting with haemoptysis following an episode of bacterial endocarditis is presented. They are extremely rare and clinically non-specific but critical because early diagnosis is crucial for preventing sudden death from their rupture. Computed tomography pulmonary angiography remains the investigation of choice.
