Multicenter Study
Blastomycosis in Indiana: Clinical and Epidemiologic Patterns of Disease Gleaned from a Multicenter Retrospective Study.
To better understand clinical and epidemiologic patterns of blastomycosis, we report on a large series of blastomycosis in Indiana. ⋯ The incidence of blastomycosis in Central Indiana may be on the rise. Physicians in endemic areas should be aware of the potentially fulminant consequences of the disease.

Randomized Controlled Trial
A double-blind placebo-controlled study of the effects of olprinone, a specific phosphodiesterase-III inhibitor, for preventing postoperative atrial fibrillation in patients undergoing pulmonary resection for lung cancer.
We previously reported that patients with elevated preoperative B-type natriuretic peptide (BNP) levels have an increased risk for postoperative atrial fibrillation following lung cancer surgery. The present study evaluated whether the specific phosphodiesterase III inhibitor olprinone can reduce the incidence of postoperative atrial fibrillation in patients with elevated BNP levels undergoing pulmonary resection for lung cancer. ⋯ Continuous infusion of olprinone during lung cancer surgery was safe and reduced the incidence of postoperative atrial fibrillation following pulmonary resection in patients with elevated preoperative BNP levels.

Inhalation/smoking has become the most common method of recreational opiate consumption in the United Kingdom and other countries. Although some heroin smokers appear to develop COPD, little is known about the association. ⋯ Recreational smoking of heroin appears to lead to early onset COPD with a predominant emphysema phenotype. This message is important to both clinicians and the public, and targeted screening and education of this high-risk population may be justified.

Case Reports
Unusual Acute Sequelae of α1-Antitrypsin Deficiency: A Myriad of Symptoms With One Common Cure.
Panniculitis associated with α1-antitrypsin deficiency (AATD) is well documented but rare. We report the first case, to our knowledge, of successful induction of clinical remission of AATD-related panniculitis following a single 120-mg/kg dose administration of plasma-purified α1-antitrypsin (AAT). A 23-year-old man with known PiZZ AATD presented to the hospital with a diffusely swollen and tender right upper limb. ⋯ There was no tenderness to palpation or induration, and a clinical remission of panniculitis was observed. We report the first case, to our knowledge, of clinical remission following a single treatment with IV AAT at a dose of 120 mg/kg. This opens avenues to more timely and effective treatment of the more severe presentations of AAT-associated panniculitis.

Randomized Controlled Trial
Lung Function in Rural Guatemalan Women Before and After a Chimney Stove Intervention to Reduce Woodsmoke Exposure: Results From RESPIRE and CRECER.
COPD is the third most frequent cause of death globally, with much of this burden attributable to household biomass smoke exposure in developing countries. As biomass smoke exposure is also associated with cardiovascular disease, lower respiratory infection, lung cancer, and cataracts, it presents an important target for public health intervention. ⋯ In these young Guatemalan women, there was no association between lung function and early randomization to a chimney stove or personal wood smoke exposure. Future stove intervention trials should incorporate cleaner stoves, longer follow-up, or potentially susceptible groups to identify meaningful differences in lung function.
