Use of a nasolacrimal stent to treat air regurgitation after dacryocystorhinostomy in a patient using a continuous positive airway pressure device.

The dacryocystorhinostomy procedure creates a direct passageway between the lacrimal sac and nasal cavity, bypassing any nasolacrimal duct obstruction. Use of a continuous positive airway pressure device after dacryocystorhinostomy can cause nasolacrimal air regurgitation. Here, we report a case of air regurgitation after dacryocystorhinostomy that was successfully treated with placement of a Mini Monoka device, a silicone stent used in nasolacrimal surgery to prevent closure of the passageway, in a patient using a continuous positive airway pressure machine. Following the procedure, the patient was able to resume use of her continuous positive airway pressure device. CITATION: Srivatsan S, Mirza M, Imayama I, Setabutr P, Mahoney NR.

A Rare Case of Fulminant Myocarditis Caused by COVID-19 and Influenza B Co-infection.

Coronavirus disease 2019 and influenza B can have similar presentations and are self-limited in most cases. They are rarely associated with fatal cardiovascular complications. Coronavirus and influenza B-induced myocarditis is a rare but reversible cause of cardiogenic shock. Early detection plus administration of antiviral agents and supportive care with mechanical circulatory support in the form of an intra-aortic balloon pump can be a lifesaving measure in myocarditis.

Sex differences in Epworth Sleepiness Scale normalization with continuous positive airway pressure.

STUDY OBJECTIVES: Continuous positive airway pressure (CPAP) improves sleepiness in patients with obstructive sleep apnea, but some patients remain sleepy. The objective of this study was to identify determinants that are associated with improvements in self-reported sleepiness in patients with obstructive sleep apnea on CPAP therapy. METHODS: A retrospective cohort study was performed in a clinic-based population to determine which variables contributed to the improvement in the Epworth Sleepiness Scale (ESS) in patients on CPAP therapy for OSA, stratified by baseline ESS score (< 11 or ≥ 11). Variables associated with ESS scores normalizing with CPAP were also assessed. RESULTS: Patients with a baseline high ESS score showed greater improvements in the ESS with CPAP. When looking at interactions between baseline ESS classification and changes in ESS, we found that a higher apnea-hypopnea index was only associated with improvement in the ESS among patients with a high baseline ESS. Other assessed factors or covariates were not significantly different. When looking at ESS normalization, we found that female sex and lower body mass index were associated with a lower likelihood of ESS normalization. The difference in the rate of ESS normalization between females and males was higher with more days on CPAP. CONCLUSIONS: Of all the assessed factors and covariates, only the apnea-hypopnea index was associated with the change in the ESS differently in patients with a high or normal baseline ESS score. ESS normalization rates were lower in females than in males, and this disparity was amplified by more days on CPAP. CITATION: Scharf MT, Zhang P, Walker NA, et al.
