Discordance in Bone Mineral Density between the Lumbar Spine and Femoral Neck Is Associated with Renal Dysfunction.
Bone mineral density (BMD) determined by dual-energy X-ray absorptiometry is considered a gold standard for diagnosing osteoporosis. Some people show discordance in BMD values measured at the femur and that at the lumbar spine (LS). The aim of the present study was to investigate whether differences in BMD T-scores between the LS and femur neck (FN) are associated with renal dysfunction in the general population of Korea. ⋯ Discordance between LS and FN BMDs was significantly associated with renal dysfunction in subjects aged ≥50 years. When assessing bone health in older chronic kidney disease patients, physicians should consider the possibility of BMD discordance between LS and FN.

Case ReportsExpeditious Resolution of Giant Bullae with Endobronchial Valves and Percutaneous Catheter Insertion.
As bullae contribute to decreased lung function in chronic obstructive pulmonary disease (COPD) patients, effective decompression of large bullae is important. Bronchoscopic lung volume reduction via endobronchial one-way valves is less invasive and has a lower mortality rate than lung volume reduction surgery. ⋯ Three days later, imaging revealed marked decreases in the extent of bullae and atelectasis of the contralateral lung without any complications, including air leakage or pneumothorax. Combination of endobronchial valves and percutaneous catheter insertion might be helpful to accelerate the release of large bullae and to achieve improved lung function and higher levels of physical activity in patients with COPD.
