Background: Pulsed-dye lasers (PDL) are one of the standard therapies for rosacea, but alternatives are needed.
Aims: To compare the efficacy and safety of the variable-sequenced, large-spot 532 nm KTP laser to the 595 nm PDL in treating rosacea.
Materials And Methods: A prospective, controlled, evaluator-blinded study. Patients were treated with either a KTP or PDL with 1-3 sessions at intervals of 6-8 weeks. A follow-up visit was scheduled on Week 6 post-treatment. Clinical outcome was assessed by computer-assisted analysis and by patients and two blinded dermatologists. Pain intensity during treatment and adverse events were documented.
Results: Forty-five patients (mean age 51 years) were allocated in a 2:1 ratio to either the KTP or PDL. Erythema in both treatment arms decreased significantly (p < 0.01). Clinical evaluation revealed high improvement. Mean pain intensity was significantly lower with the KTP (2.5/10) than with the PDL (4.1/10). Both lasers showed a good safety profile. Relevant purpura was only seen in the PDL group.
Conclusions: Both the variable-sequenced, large-spot KTP and the PDL demonstrated comparable efficacy in treatment of rosacea. Regarding safety, the KTP exhibited fewer post-treatment reactions. The KTP might serve as a potential alternative to PDL in the treatment of rosacea.

Successful Multi-Modal Laser Intervention and Histopathological Evaluation of Multiple Glomangiomas.
Lasers Surg Med
December 2024
Department of Dermatology, Veterans Health Administration, San Antonio, Texas, USA.
Objectives: Glomangiomas are benign vascular malformations that exist within the spectrum of glomuvenous malformations which consist of varying amounts of glomus cells, vascular spaces, and smooth muscle. Glomangiomas are often treated due to associated pain, particularly when located on pressure areas such as the back or extensor surfaces, which can cause difficulty with certain activities and occupational functions. Histologically glomangiomas consist of prominent dilated vascular spaces lined by glomus cells typically situated in the deep-dermis to subcutaneous fat which limits treatment to modalities capable of reaching the depth of the tumor including excision, sclerotherapy, and laser therapy.

Consultant Dermatologist, Aalborg University, Aalborg, Denmark.
Objective: We aimed to document the treatment outcomes of African patients treated with low-intensity electrodesiccation for DPN's. Other treatment options for DPN's include snip excision, light curettage, cryotherapy, and lasers devices such as PDL, Nd: YAG, KTP, and CO2, which are generally unsafe for darker skin types and come with high costs.
Methods: Nonprobability convenience sampling of patient records was used to extract retrospective data on demographics and treatment outcomes according to the inclusion criteria.
The effect of capping agent on morphology, surface functionalization, and bio-compatibility properties of KTiOPO nanoparticles.

Department of Tissue Engineering and Applied Cell Sciences, School of Medicine, Semnan University of Medical Sciences, Semnan, Iran.
KTiOPO (KTP) nanoparticles (NPs) are potential materials as biolabels for long-term imaging. Optimizing their properties can lead to higher imaging efficiency and lower cytotoxicity and side effects. In this study, these nanoparticles were synthesized using the co-precipitation method and capping agents of oxalic acid and glycine.

Department of Otolaryngology-Head and Neck Surgery, University of Alabama at Birmingham, Birmingham, AL, USA.
Objectives: Transoral robotic surgery (TORS) for benign glottic conditions is scarcely represented in the literature. We aimed in this study to report on the technical feasibility of an explicitly transoral robotic approach for a patient with posterior glottic stenosis, and to highlight extant limitations in exposure and robotic instrumentation of the glottis.
Methods: Retrospective chart review of a single patient undergoing a TORS approach to maximize the posterior glottic aperture.
Novel In-Office KTP Laser Treatment of Anterior Glottic Webs.
J Voice
November 2024
Department of Otolaryngology - Head and Neck Surgery, USC Voice Center, University of Southern California, Los Angeles, CA. Electronic address:
Objective: Acquired anterior glottic webs are the result of trauma, iatrogenic, radiation, or inflammation to the anterior commissure, resulting in narrowing of the airway and elevated pitch. They are very challenging to treat, and contemporary management strategies typically involve repeat procedures under general anesthesia with high rates of web recurrence. We aim to describe a novel treatment for anterior glottic webs with potassium titanyl phosphate (KTP) laser treatment that are performed in-office under topical anesthesia.
