Published: May 2021

Abnormalities of vocal cord motion in children with obstructive sleep apnea (OSA) who undergo drug-induced sleep endoscopy (DISE) are not frequently described. A 17-year-old female with a history of asthma, reflux, and bipolar disorder had a history of poor sleep. Polysomnography (PSG) showed apnea-hypopnea index (AHI) of 13.9/hr, obstructive AHI 10.3/hr, and oxygen saturation nadir 87%. Physical exam showed BMI 34 and 3+ tonsils. She underwent DISE with propofol infusion, which showed partial obstruction at the palatine and lingual tonsil levels, a posteriorly displaced epiglottis along with immobility of the left vocal cord. Tonsillectomy was performed as planned. At her post-op visit, laryngoscopy showed normal vocal cord motion bilaterally. Post-operative PSG was improved.

Background: The approval of anti-amyloid monoclonal antibodies (mAbs) provides a novel approach to the treatment of Alzheimer's disease. Infusions in alternative sites of care can benefit the patient financially and logistically, but coverage is largely payor dependent. The purpose of this study is to describe observations from this national complex specialty pharmacy around the safety of anti-amyloid mAb infusions in alternative sites of care, including the home.

Objective: For neonatal repair of coarctation of the aorta, patients may either undergo thoracotomy with extended end-to-end anastomosis or sternotomy for aortic arch reconstruction with cardiopulmonary bypass. The objective of this study was to evaluate the comparative effectiveness of the 2 approaches in patients with arch hypoplasia.

Methods: This is a single-center retrospective cohort study from July 2005 through May 2022 of patients who underwent neonatal repair for isolated coarctation of the aorta with additional arch hypoplasia.

Though several studies have demonstrated that preoperative oral feeding (PO) can be safe in patients with congenital heart disease, they are commonly prohibited from doing so, potentially precluding the development of such skills. We sought to determine whether preoperative oral feeding is associated with freedom from tube feeding at postoperative discharge. Single-center, observational study including patients in the first month of life (≤ 30 days of age) who underwent a single cardiac surgery between 7/1/2017-6/30/2022 and survived to discharge.

Successful awake intubation using Airtraq in a low-resource setting for a patient with severe post-burn contractures.

BMC Anesthesiol

January 2025

Department of Anesthesiology, Pharmacology, Intensive Care and Emergency Medicine, University Hospitals of Geneva, Geneva, 1205, Switzerland.

Background: In resource-limited settings, advanced airway management tools like fiberoptic bronchoscopes are often unavailable, creating challenges for managing difficult airways. We present the case of a 25-year-old male with post-burn contractures of the face, neck, and thorax in Nigeria, who had been repeatedly denied surgery due to the high risk of airway management complications. This case highlights how an awake intubation was safely performed using an Airtraq laryngoscope, the only device available, as fiberoptic intubation was not an option.

Evaluation of Swallowing Dysfunction With Flexible Endoscopic Evaluation of Swallowing in the Neonatal Unit.

Am J Speech Lang Pathol

January 2025

Division of Neonatology, Department of Child Health, Phoenix Children's Hospital, Phoenix Campus, The University of Arizona.

Background: Preterm and low-birth-weight infants often experience discoordination of the suck-swallow-breathe pattern, leading to dysrhythmic feeding, inefficient feeding skills, and swallowing dysfunction, increasing the risk of aspiration and respiratory morbidity. While videofluoroscopic swallowing study is commonly utilized to assess swallow function in neonates, flexible endoscopic evaluation of swallowing (FEES) has been an emerging modality and has been utilized routinely at our institution since 2018.

Method: A single-center, retrospective study including 90 infants admitted to the neonatal unit between 2018-2023 who underwent FEES procedure.
