A 56-year-old man presented to the ED of an outside hospital with 2 days of bleeding gums and easy bruising. He denied episodes of melena, hematemesis, or hematuria and had no epistaxis. ⋯ A bone marrow biopsy confirmed the diagnosis of acute promyelocytic leukemia. He was transferred to our hospital for treatment.

Patients with pulmonary arteriovenous malformations (PAVMs) are unusual because hypoxemia results from right-to-left shunting and not airway or alveolar disease. Their surprisingly well-preserved exercise capacity is not generally appreciated. ⋯ Patients with hypoxemia and PAVMs can maintain normal oxygen delivery/VO₂ during peak exercise. Following improvement of SaO₂ by embolization, patients appeared to reset compensatory mechanisms and, as a result, achieved similar peak VO₂ per heart beat and peak work rates.

In the 13 years since their promulgation, the Health Insurance Portability and Accountability Act (HIPAA) rules and their enforcement have shown considerable evolution, as has the context within which they operate. Increasingly, it is the health information circulating outside the HIPAA-protected zone that is concerning: big data based on HIPAA data that have been acquired by public health agencies and then sold; medically inflected data collected from transactions or social media interactions; and the health data curated by patients, such as personal health records or data stored on smartphones. HIPAA does little here, suggesting that the future of health privacy may well be at the state level unless technology or federal legislation can catch up with state-of-the-art privacy regimes, such as the latest proposals from the European Commission.
