Obesity is known to be an important risk factor for OSA; however, OSA can also be seen in nonobese patients with a small maxilla and/or mandible as well as in all obese patients with such features. Thus, we hypothesized that regional factors, oropharyngeal crowding associated with fat deposition, and maxillomandibular enclosure size closely related to the severity of OSA. ⋯ Oropharyngeal crowding is a local anatomic factor that independently relates to the severity of OSA in both obese and nonobese patients; the more crowded the upper airway, the more severe the OSA.

A 57-year-old man with a history of DVT and pulmonary embolism, transient ischemic attacks, prior 60 pack-year smoking history, and oxygen-dependent COPD presented with insidiously worsening dyspnea associated with new pleuritic chest and back pain.

Observational Study
Deep vein thrombosis management and outcome trends, 2001 to 2014.
A comprehensive evaluation of temporal trends in the treatment of patients who have DVT may assist with identification of modifiable factors that contribute to short-term outcomes. ⋯ This international registry-based temporal analysis identified reductions in length of stay for adults hospitalized for DVT. The study also found a decreasing trend in adjusted rates of all-cause and bleeding-related mortality.

Case Reports
A 51-Year-Old Woman With Hypoacusia and Increased Respiratory Effort in the Supine Position and OSA.
A 51-year-old woman with a personal history of vitiligo, normal thyroid hormone studies, a simple hysterectomy for multiple uterine myomas at age 35 years, and childhood adenotonsillectomy was seen for progressive hearing loss. She reported mild asthenia, cold intolerance, mild dysphagia with frequent choking while eating and drinking, and a progressive increase in inspiratory effort, especially in the supine position. Her partner described a progressively worsening history of snoring and witnessed apneic episodes, mostly in the supine position. Mild to moderate daytime sleepiness was also present.

A young woman received a diagnosis of abdominal, sporadic lymphangioleiomyomatosis (LAM) and multiple abdominal lymphangioleiomyomas and was referred for recurrent chylous ascites responding only to a fat-free diet. On admission, pulmonary function test (PFT) results showed a moderate reduction in the transfer factor for carbon monoxide with normal exercise performance. The serum vascular endothelial growth factor D (VEGF-D) level was 2,209 pg/mL. ⋯ PFT results were stable. Interestingly, clinical improvement was associated with a reduction in the VEGF-D serum level (1,558 pg/mL). LOH at the kg8 biomarker in blood LAM cells was no longer detected.
