Little is known about adherence to asthma biologics. ⋯ Adherence to asthma biologic is higher than to ICS and is associated with different factors.

A 40-year-old woman presented with recurrent syncope. She reported multiple (>20) episodes of non-prodromal loss of consciousness, periodically provoked by physical exertion. One episode resulted in a nasal fracture due to the abrupt nature of her syncope. ⋯ Initial workup, including complete blood count, comprehensive metabolic panel, cardiac enzymes, and ECG yielded normal results. The chest radiograph did not show any gross cardiac or pulmonary parenchymal pathologic condition (Fig 1). Telemetry did not demonstrate any malignant arrhythmias, and video-guided EEG did not document any seizure activity.

A 14-year old girl presented with history of productive cough since the age of 3 years. For the past 6 years, she complained of chest tightness and wheezing. There was also nasal stuffiness and discharge for the past 6 years. ⋯ There was no history of respiratory distress at the time of birth. Her brother also suffered from productive cough and wheezing since the age of 3 years. However, both her parents were asymptomatic.

A 50-year-old woman was initially seen in 2016 for sleep disorders consultation, referred by Neurology because of progressive cerebellar ataxia syndrome with possible autonomic involvement and sleep-disordered breathing described as having stridorous sounds during her sleep. She had initially presented to Neurology because of issues with balance, and she had frequent falls at home. In 2016, her speech was clear, and she was able to ambulate steadily with a cane. ⋯ However, the study demonstrated rapid eye movement (REM) sleep without atonia in 62% of REM epochs (normal, up to 27%) and a soft inspiratory stridor during non-REM and REM sleep. The patient was lost to follow-up until she presented to us for reevaluation 3 years later. In the interim, she had been diagnosed with multiple system atrophy-cerebellar type (MSA-C) at another health-care institution.

Hypoglossal nerve stimulation (HNS) is an alternative treatment option for patients with OSA unable to tolerate positive airway pressure but implant criteria limit treatment candidacy. Previous research indicates that caudal tracheal traction plays an important role in stabilizing upper airway patency. ⋯ ACS independently increased VImax during propofol sedation and drove further increases in VImax when combined with HNS. The branch of the ansa cervicalis innervating the sternothyroid muscle is easily accessed. Confirmation of the ansa cervicalis as a viable neurostimulation target may enable caudal pharyngeal traction as a novel respiratory neurostimulation strategy for treating OSA.
