Multidrug-resistant (MDR) bacteria and their associated biofilms are major causative factors in eye infections, often resulting in blindness and presenting considerable global health challenges. Presently, mechano-bactericidal systems, which combine distinct topological geometries with mechanical forces to physically induce bacterial apoptosis, show promising potential. However, the physical interaction process between current mechano-bactericidal systems and bacteria is generally based on passive diffusion or Brownian motion and lacks the force required for biofilm penetration; thus, featuring low antibacterial efficacy.

This case concerns a boy presenting with oral pain and multiple mucocutaneous lesions such as mucositis, conjunctivitis, and a rash on the trunk, extremities, and genitalia. The presence of mild respiratory complaints raised suspicion of an extrapulmonary manifestation of , known as -induced Rash and Mucositis (MIRM). The patient underwent conservative treatment and was monitored to prevent chronic sequels such as ocular damage or sicca keratoconjunctivits.

Diabetic wounds often exhibit a chronic non-healing state due to the combined effects of multiple factors, including hyperglycemia, impaired angiogenesis, immune dysfunction, bacterial infection, and excessive oxidative stress. Despite the availability of various therapeutic strategies, effectively managing the complex and prolonged healing process of diabetic infected wounds remains challenging. In this study, we combined the natural antidiabetic drug lipoic acid (LA) with the RADA16-YIGSR (RY) peptide obtained through solid-phase synthesis, utilizing reversible hydrogen bonds and coordination bonds for binding.

Purpose: To characterize the ocular surface microbiota in regular contact lens wearers with dry eyes and assess the effectiveness of reducing bacterial load using a liposomal ozonated oil solution.
Methods: This prospective, longitudinal, controlled study randomized subjects into two groups. Group A (45 subjects) received hydroxypropylmethylcellulose (HPMC, Artific®), while Group B (41 subjects) received ozonated sunflower seed oil with soybean phospholipids (OSSO, Ozonest®).

Purpose: Preclinical studies have confirmed the safety and efficacy of narrowband low-intensity ultraviolet C light (UVC) in managing bacterial corneal infection. To further consolidate these findings, the present study aimed to explore in vitro anti-biofilm efficacy of low-intensity UVC light for its potential use in biofilm-related infections.
Methods: Pseudomonas aeruginosa biofilm was grown in chamber well slides for 48 h and exposed to one of the following challenges: UVC (265 nm wavelength, intensity 1.
