OSA is associated with changes in pharyngeal anatomy. The goal of this study was to objectively and reproducibly quantify pharyngeal anatomy by using digital morphometrics based on a laser ruler and to assess differences between subjects with OSA and control subjects and associations with the apnea-hypopnea index (AHI). To the best of our knowledge, this study is the first to use digital morphometrics to quantify intraoral risk factors for OSA. ⋯ Measures of tongue size, airway visibility, and Mallampati scores were associated with increased OSA risk and severity. This study shows that digital morphometrics is an accurate, high-throughput, and noninvasive technique to identify anatomic OSA risk factors. Morphometrics may also provide a more reproducible and standardized measurement of the Mallampati score. Digital morphometrics represent an efficient and cost-effective method of examining intraoral crowding and tongue size when examining large populations, genetics, or screening for OSA.

Community-Acquired Pneumococcal Pneumonia in Virologically Suppressed HIV-Infected Adult Patients: A Matched Case-Control Study.
The study aimed to investigate whether the clinical presentations and outcomes (length of stay, ICU admission, and 30-day mortality) of pneumococcal pneumonia in virologically suppressed patients who were HIV-infected on ART with a CD4+ T-cell count > 350 cells/mm3 are comparable to those seen in patients with HIV, using a case-control design. ⋯ Pneumococcal pneumonia episodes requiring hospitalization in virologically suppressed patients with HIV with > 350 CD4+ T-cell count/mm3 were neither more severe nor had worse prognosis compared with uninfected patients. These results support the fact that such patients do not need treatment, admission, or care sites different to the general population.

An 18-year-old African American male subject presented to an acute care clinic with 3 days of productive cough, chills, pleuritic right chest pain, sore throat with hoarseness, congestion, and intermittent shortness of breath. He recently relocated to Texas from Georgia to undergo basic military training. He denied any other recent travel or contact with persons with pulmonary TB or other respiratory illnesses. His medical history was significant for glucose-6-phosphate dehydrogenase deficiency and sickle cell trait.
