Swyer-James-Macleod syndrome (SJMS) is a rare constrictive bronchiolitis with air-flow obstruction and a decreased number and diameter of ipsilateral peripheral pulmonary vessels. This syndrome is characterized by unilateral hyperlucency on chest radiography. Computed tomography provides useful additional information. ⋯ The disease often presents with dyspnea, decreased exercise tolerance, cough, hemoptysis, and recurrent pulmonary infections. SJMS may be confused with asthma or pulmonary embolism due to similar symptoms and may result in inappropriate therapy. This case series examined the clinical and imaging spectrum of four patients who were diagnosed with SJMS in adulthood.

Gait speed is a simple physical function measure associated with key outcomes in the elderly population. Gait speed measurements may improve clinical care in patients with COPD. However, there is a knowledge gap about the reliability and variability of gait speed testing protocols in COPD. We evaluated established techniques of measuring gait speed in patients with COPD and assessed feasibility of implementing gait speed as a routine vital sign in an out-patient clinic. ⋯ Gait speed is a reliable measure in COPD, regardless of instructed pace, distance, or timing mechanism; however, adhering to one protocol is suggested. 4MGS was easily implemented into clinical practice with high acceptability by patients and clinic staff.

There have been few reports of factors affecting aerosol delivery during noninvasive ventilation (NIV). Nebulization is a standard practice, and our objective was to determine the effect of spontaneous breathing (SB) and NIV mode on lung technetium-99m ((99m)Tc) deposition in subjects with normal lungs. ⋯ Based on our data, there is an equivalent deposition of inhaled substances in individuals with healthy lungs when SB, CPAP, and bi-level are compared.

Chronic neck pain is one of the most common musculoskeletal pain conditions experienced by many people during their lives. Although patients with neck pain are managed predominantly as musculoskeletal patients, there are indications that they also have poor pulmonary function. The aim of this study was to examine whether patients with chronic neck pain have spirometric abnormalities and whether neck pain problems and psychological states are associated with these abnormalities. ⋯ Patients with chronic neck pain do not have optimal pulmonary function. Cervical spine muscle dysfunction in parallel with pain intensity and kinesiophobia are factors that are associated mainly with this respiratory dysfunction.
