Alpha-lipoic acid does not improve olfactory training results in olfactory loss due to COVID-19: a double-blind randomized trial.

Objectives: Olfactory loss is a recognized long-term dysfunction after Coronavirus Disease 2019 (COVID-19) infection. This investigation aimed to assess the effect of alpha-lipoic acid as an adjuvant treatment of olfactory training on the improvement of smell loss in post-COVID-19 patients.

Methods: This randomized controlled trial included 128 adult outpatients who had persistent smell loss for more than 3-months after COVID-19 infection.

Safety for the Rhinologist in the Age of COVID-19: Mask Use, Nasal Corticosteroids, Saline Irrigation, and Endoscopic Procedures - Literature Review.

 Coronavirus disease 2019 (COVID-19) has claimed millions of lives. Adequate protection of the professionals involved in patient care is essential in the battle against this disease. However, there is much uncertainty involving safety-relarted topics that are of particular interest to the rhinologist in the context of COVID-19.

High Anti- IgG Antibody Levels Are Associated With Severity of Mucosal Leishmaniasis.

Background: Mucosal leishmaniasis (ML), the most inflammatory form of tegumentary leishmaniasis, is predominantly caused by . The disease is characterized by the development of lesions, mainly in the nasal mucosa. An exacerbated inflammatory response has been associated with the presence of destructive and disfiguring lesions, with stages of severity ranging from small nodulations to the complete destruction of the nasal pyramid architecture.

In Situ Cellular Response Underlying Successful Treatment of Mucosal Leishmaniasis with a Combination of Pentavalent Antimonial and Pentoxifylline.

Mucosal leishmaniasis (ML) is characterized by high production of inflammatory cytokines. Administration of pentoxifylline (PTX), an inhibitor of TNF-alpha, with pentavalent antimony (Sb), has been successfully used as alternative treatment for refractory ML. Our study aims to investigate the in situ cellular response underlying the effectiveness of this therapy, by evaluating the intensity of the inflammatory infiltrate, cellular composition, and expression of cytokines and granzyme A in lesions from ML before and after treatment with Sb alone or in combination with PTX.

Relations among perceived control over anxiety-related events, worry, and generalized anxiety disorder in a sample of adolescents.

This study examined the associations among perceived control over anxiety-related events, worry, and both symptoms and diagnoses of generalized anxiety disorder (GAD). The sample was comprised of 140 adolescents (60 girls) between the ages of 10 and 17 years (M ( age ) = 14.6 years; SD = 2.
