To examine the effects of surgery for unilateral sinonasal lesions on sleep-disordered breathing (SDB). Oxygen desaturation index (3%ODI) as a marker of SDB and bilateral/unilateral nasal resistance were measured before and after surgery for 18 patients with unilateral sinonasal lesions. Various parameters were compared between those who achieved 60% or less decrease of 3%ODI and those who did not. Bilateral nasal resistance as well as that of the surgical side five days after surgery was significantly lower than those of pre-operative value. Preoperative 3%ODI (times/hour) was 10.08 ± 7.32, which significantly decreased to 7.67 ± 5.79 five days after surgery. Even in unilateral patients, sinonasal surgery could reduce the bilateral nasal resistance, resulting in a decrease in 3%ODI. Age was younger and postoperative nasal resistance of the surgical side was significantly lower in the group who achieved 60% or less decrease in 3%ODI than those who did not. SDB is influenced by even unilateral nasal obstruction. Surgery for unilateral lesion can improve the respiration during sleep as well as bilateral nasal resistance. Favorable outcome by surgery could be brought about in younger patients and those for whom sufficient improvement of nasal resistance was expected by surgery.

Australian Defence Force Malaria and Infectious Disease Institute, Enoggera, QLD 4051, Australia.
Objective: Staphylococcus aureus (SA), including methicillin-resistant strains (MRSAs), is a major cause of skin and soft tissue infections (SSTIs) in military populations. This study investigated SSTI incidence and SA carriage in a military training site over 16 weeks using a prospective observational cohort design.
Methods: Two training cohorts provided pre- and post-training self-collected swabs for bacterial carriage, and environmental swabs from accommodations, personal items, and training facilities.

A Fatal Outcome of Ludwig's Angina and Necrotizing Fasciitis Following Traditional Tooth Extraction.
Int Med Case Rep J
December 2024
Department of Oral and Maxillofacial Surgery, Kampala International University-Teaching Hospital, Bushenyi, Uganda.
Ludwig's angina is a potentially fatal condition characterized by a rapid onset of cellulitis that bilaterally involves the submandibular, sublingual, and submental spaces. This report describes the case of a 29-year-old female who presented to us with Ludwig's angina following a tooth extraction performed by a traditional healer in Southwestern Uganda. The patient stayed home for over a week before she could seek formal treatment, and this delay led to severe infection and necrotizing fasciitis with extensive tissue necrosis.
