Review Case Reports
Massive pulmonary emboli in children: does fiber-optic-guided embolectomy have a role? Review of the literature and report of two cases.
Massive pulmonary emboli is a rare disease in children, with only 39 reported cases in the last 50 years. Almost 50% of the patients died suddenly without receiving medical treatment. Most of the patients who were managed medically (70% of the treated patients) underwent surgical pulmonary embolectomy with 80% survival. ⋯ This technique was reported in adults with good results. In this article, we describe two pediatric patients who underwent fiber-optic-guided surgical pulmonary embolectomy. To our knowledge, this technique has never been reported in the pediatric population.

The positive results of a screening CT scan trial are likely to lead to an increase in the use of CT scanning, and, consequently, an increase in the detection of subsolid nodules. Noninvasive methods including follow-up with CT scanning, to determine which nodules require invasive diagnosis and surgical treatment, should be defined promptly. ⋯ An effective schedule for follow-up with CT scanning for subsolid nodules should be developed according to the type of subsolid nodule, initial nodule size, and history of lung cancer.

Randomized Controlled Trial
Benefits of intensive treadmill exercise training on cardiorespiratory function and quality of life in patients with pulmonary hypertension.
Pulmonary hypertension (PH) restricts the ability to engage in physical activity and decreases longevity. We examined the impact of aerobic exercise training on function and quality of life in patients with World Health Organization group 1 PH. ⋯ Ten weeks of brisk treadmill walking improved 6MWT distance, cardiorespiratory function, and patient-reported quality of life in female patients with group 1 PH.

Obstructive sleep apnea is increasingly recognized as a comorbidity in many medical illnesses. This has resulted in an increasing need for sleep testing, which is not entirely met by the currently available sleep laboratory facilities. ⋯ However, coding and billing for home studies is not as straightforward as it is for in-laboratory studies. This article reviews the process of coding and billing for sleep studies done in an unattended setting.

T helper 17 (Th17) cytokines are now widely believed to be critical for the regulation of various chronic immune diseases. Investigations have revealed a significant role for IL-17 cytokines in regulating inflammation and modulating lung and airway structural cells in asthma and COPD. In this review, our current understanding of the role of Th17-associated cytokines in airway diseases is summarized. Therapeutic approaches targeting IL-17 during asthma and COPD are also discussed.
