Actinic cheilitis (AC) is a premalignant lesion of the lips that can evolve into squamous cell carcinoma. Among nonsurgical treatments, photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) patch might represent a new noninvasive therapeutic approach for AC. We sought to investigate the potential role of fractional CO laser pretreatment in boosting ALA penetration and distribution into AC treated with PDT. We report a case of a woman with AC on the lower lip, treated with ablative fractional CO laser to boost drug delivery of 5-ALA patch before PDT treatment. Reflectance confocal microscopy was performed to assess diagnosis and treatment response. We detected a good clinical and cosmetic outcome after two applications of combined treatment. Erythema, crust, and edema were reported as side effects. This case report shows that ablative fractional CO laser-assisted PDT might be an effective therapeutic alternative for patients with AC who refuse or are contraindicated for surgical procedures.

Composite nanozymes are composed of enzymes with similar or different catalytic capabilities and have higher catalytic activity than a single enzyme. In recent years, composite nanozymes have emerged as novel nanomaterial platforms for multiple applications in various research fields, where they are used to produce oxygen, consume glutathione, or produce toxic reactive oxygen species (ROS) for cancer therapy. The therapeutic approach using composite nanozymes is known as chemo-dynamic therapy (CDT).

The morbidity of oral disorders, including gingivitis, caries, endodontic-periodontal diseases, and oral cancer, is relatively high globally. Pathogenic cells are the root cause of many oral disorders, and oral therapies depend on eradicating them. Photodynamic therapy (PDT) has been established as a potential and non-invasive local adjuvant treatment for oral disorders.

This study is the first to use photodynamic therapy (PDT) mediated by curcumin and blue light for the treatment of recurrent herpes labialis. According to our study, PDT effectively accelerated lesion healing and reduced its recurrence. PDT may represent a promising, safe, and cost-effective treatment option for this challenging disease.

A juxtapapillary retinal capillary hemangioma (JRCH) is a rare vascular hamartoma located on the optic nerve head or adjacent region. While often associated with von Hippel-Lindau (VHL) disease, JRCHs can also occur as an isolated condition, presenting unique therapeutic challenges and risks of visual impairment. We report a case of a 50-year-old Malay gentleman with diabetes mellitus who presented with a non-progressive superior visual field defect in his left eye for three months.

Despite phthalocyanine has excellent photodynamic and photothermal effects as a photosensitizer and photothermal agent, hydrophobicity and aggregation limits its biological application. In this paper, phthalocyanine-cyanine co-assembled nanoparticles were designed to modulate the dimensions and morphology by introducing water-soluble cyanine. The cyanine had the ability to transform the nanomaterials from microrods to nanospheres, thus successfully constructing photoactivated nanomedicines.
