A 51-year-old man was admitted for evaluation of new-onset generalized seizures in the context of progressive and significant behavioral change. His medical history was only notable for previous outbreaks of genital herpes. He took no medications. ⋯ He was prescribed antiseizure medications and scheduled for an outpatient workup. However, with progressive gait instability, lethargy, and an increase in frequency of generalized seizures, the patient was admitted for treatment of suspected viral encephalitis. Despite initiation of antimicrobial and antiviral therapy, the patient's level of alertness continued to decline, ultimately leading to intubation for airway protection.

The underlying cause of cystic fibrosis (CF) is the loss of epithelial chloride and bicarbonate transport due to mutations in the CF transmembrane conductance regulator (CFTR) gene encoding the CFTR protein. Ivacaftor is a gene-specific CFTR potentiator that augments in vivo chloride transport in CFTR mutations affecting channel gating. ⋯ We report marked clinical improvement, normalization of spirometry, and dramatic reduction in radiographic structural airway changes after > 1 year of treatment with ivacaftor in a young adult with the compound heterozygous genotype P67L/F508del CFTR. The case suggests that ivacaftor may have a potential benefit for patients with CF with nongating mutations.

A healthy 55-year-old man without known medical problems presented for a routine physical examination and was found to have an abnormal ECG. He denied chest pain, dyspnea, palpitations, dizziness, or syncopal episodes. ⋯ His exercise capacity had been excellent. He was a lifelong nonsmoker and never had lung problems.

A teenager was admitted to an outside hospital ED following an episode of melena. He had been complaining of intermittent abdominal pain, nausea, malaise, and easy fatigability for 2 months, with significant worsening of symptoms 2 weeks prior to this episode. ⋯ On presentation at the outside ED, he was found to be profoundly icteric and encephalopathic. Initial laboratories suggested anemia, acute kidney injury, and acute liver failure, leading to a presumptive diagnosis of acute fulminant liver failure necessitating transfer to our institution.

Because of the rapid increase in the volume and costs of polysomnography and other sleep medicine diagnostic services, the Centers for Medicare & Medicaid Services (CMS) recently commissioned the Office of Inspector General (OIG) to review claims submitted for these services. The OIG found numerous cases of inappropriate payment for submitted claims and recommended significant changes in the CMS auditing process for polysomnography claims review. Additionally, a local Medicare Administrative Contractor released the most specific rules and regulations to date regarding billing and payment for sleep medicine services. ⋯ Providers of sleep medicine services must be prepared to provide documentation of diagnoses and indications when submitting claims for sleep services, and they can expect to be required to produce evidence of accreditation of the physicians and technologists providing services and the credentials of the sleep center. These changes will dramatically affect sleep medicine practitioners who order sleep studies and positive airway pressure therapies. Successful sleep medicine centers and sleep physicians alike will need to develop strategies to meet these new challenges.
