Potential effect of topical antibiotics administration in the oral cavity on the reduced number of bacteria entering the lower respiratory tract after oral cancer surgery.
J Dent Sci
January 2025
Department of Oral and Maxillofacial Surgery, Nagasaki University Graduate School of Biomedical Sciences, Nagasaki, Japan.
Background/purpose: One of the causes of ventilator-associated pneumonia (VAP) is aspiration of oropharyngeal fluid containing pathogenic microorganisms into the lower respiratory tract. In this study, we aimed to investigate whether antibiotic ointment applied to the oral cavity can reduce the number of bacteria in the fluid on the cuff of a tracheal cannula.
Materials And Methods: Tetracycline ointment was applied intraorally once to a patient under endotracheal intubation by postoperative tracheostomy for oral cancer.
Investigation of the participation of the TRPV1 receptor in the irritant effect of dithranol in mice.

Dithranol is one of the most effective topical medications for treating plaque psoriasis. However, its clinical use is limited by irritative adverse reactions to the skin, such as oedema, erythema, and pruritus, caused by poorly understood mechanisms. Because TRPV1 activation mediates skin irritation caused by several drugs, we conducted blind and randomised experiments in male and female C57BL/6 mice to elucidate the role of TRPV1 in dithranol-induced irritation.

Introduction: Recurrent uveitis (RU), an autoimmune disease, is a leading cause of ocular detriment in humans and horses. Equine and human RU share many similarities including spontaneous disease and aberrant cytokine signaling. Reduced levels of SOCS1, a critical regulator of cytokine signaling, is associated with several autoimmune diseases.

Aesthet Surg J Open Forum
December 2024
Hyaluronic acid fillers rarely cause potentially devastating occlusive adverse events that require immediate hyaluronidase salvage infiltrations. An exploratory photographic investigation probed whether topical heparin's anticlotting and anti-inflammatory properties could synergize with and enhance the effectiveness of hyaluronidase. Based on heparin pharmacodynamics, the authors explored the rationale for associating topical heparins with hyaluronidase in treating occlusive side effects following accidental intra-arterial hyaluronic acid injections.

January 2025
Department of Biological Sciences, University of Cincinnati, Cincinnati, OH, USA.
Background: Bed bugs are blood-feeders that rapidly proliferate into large indoor infestations. Their bites can cause allergies, secondary infections and psychological stress, among other problems. Although several tactics for their management have been used, bed bugs continue to spread worldwide wherever humans reside.
