Arthroscopic Stabilization of Chronic Acromioclavicular Joint Dislocations: Triple- Versus Single-Bundle Reconstruction.
Arthroscopically assisted single-bundle (SB) or double-bundle coracoclavicular (CC) ligament reconstruction using autologous tendon grafts has been reported to provide acromioclavicular (AC) joint (ACJ) stability in chronic instability cases. Recently, additional AC ligament reconstruction to provide triple-bundle (TB) stabilization has been introduced but lacks a comparison of clinical and radiological outcomes. ⋯ Combined arthroscopically assisted anatomic TB CC and AC ligament reconstruction using an autologous semitendinosus tendon graft provides superior clinical and radiological results compared with isolated nonanatomic SB CC ligament reconstruction using the AC GraftRope system. In particular, the TB technique can better restore horizontal ACJ stability, which is associated with superior ACJ-specific outcome scores.

Randomized Controlled TrialEffects of neck-specific exercises compared to waiting list for individuals with chronic whiplash associated disorders: a prospective randomized controlled study.
To determine whether 3 months of neck-specific exercises (NSEs) could benefit individuals with chronic whiplash-associated disorder (WAD) who were on a waiting list (WL) for treatment. ⋯ NSEs were more beneficial than no intervention while on a WL for individuals with chronic WAD.

An 82-year-old Japanese nonsmoking man presented with persistent dry cough and small left apical pneumothorax. High resolution CT scan of the chest demonstrated bilateral upper lobe pleuroparenchymal thickening and architectural distortion. Serial imaging revealed mild progression and development of small bilateral pneumothoraces, and pneumomediastinum. A surgical lung biopsy was required to confirm the diagnosis.

Cigarette smoking is a major environmental contributor to COPD, but understanding its epigenetic regulation of oxidative genes involved in the pathogenesis of COPD remains elusive. ⋯ Cigarette smoke-induced hypermethylation of the GCLC promoter is related to the initiation and progression of COPD. Our finding may provide a new strategy for COPD intervention by developing demethylation agents targeting GCLC hypermethylation.

A 39-year-old white woman with a history of adult-onset asthma, chronic sinusitis, and nasal polyposis presented to the ED with dyspnea and left lower extremity weakness and pain. Three months prior to her presentation she had an uncomplicated delivery of her second child, but during her pregnancy she experienced increasing asthma symptoms and nasal congestion. These symptoms progressed after delivery despite treatment with albuterol inhalers and antibiotics.
