Tinnitus is a perception disorder of sound with no hearing impulse. It is a very common otology complaint that leads to worsening quality of life. The experience of sound is only the product of neural system activity, with no matching mechanical or vibratory activity in the cochlea, and is unrelated to any external stimuli. Low-level laser therapy (LLLT) is a medical treatment of tinnitus that uses low-energy-level lasers or light-emitting diodes to stimulate or inhibit cellular function. The study included nine patients aged 20-68 years with unilateral or bilateral tinnitus...

The aim of this study is to evaluate changes in vaginal pH and epithelium maturation after erbium-doped yttrium aluminum garnet (Er-YAG) laser treatment, and to assess its safety and efficacy on the symptoms of genitourinary syndrome of menopause (GSM). This was a retrospective study conducted between November 2019 and April 2022 and included 32 women diagnosed with GSM who had not benefitted from lubrication treatment and could not or would not use estrogen. Patients received three sessions of Er- YAG laser...

Solar lentigo (SL) commonly occurs as hyperpigmented macules in areas exposed to ultraviolet radiation. It typically shows an increased number of melanocytes in the basal cell layer of the skin, with or without elongated rete ridges. This retrospective study aimed to evaluate the characteristic dermoscopic patterns, reflecting different histopathological features, which might be valuable in predicting the possibility of postinflammatory hyperpigmentation (PIH) occurring after laser treatment. In total, 88 Korean patients diagnosed with biopsy-proven SL (a total of 90 lesions were diagnosed) between January, 2016 and December, 2021 were included...

Diabetic wounds are categorized by chronic inflammation, leading to the development of diabetic foot ulcers, which cause amputation and death. Herewith, we examined the effect of photobiomodulation (PBM) plus allogeneic diabetic adipose tissue-derived stem cells (ad-ADS) on stereological parameters and expression levels of interleukin (IL)-1ß and microRNA (miRNA)-146a in the inflammatory (day 4) and proliferation (day 8) stages of wound healing in an ischemic infected (with 2×107 colony-forming units of methicillin-resistant Staphylococcus aureus) delayed healing wound model (IIDHWM) in type I diabetic (TIDM) rats...

Holmium: YAG (Ho: YAG) laser lithotripsy with flexible ureterorenoscopy can be used with high stone-free and low complication rates for renal stones. This study aimed to determine the factors affecting the total laser energy in cases with provided stone-free status after a single session of retrograde intrarenal surgery (RIRS). Data of 222 patients who underwent RIRS between October 2017 and March 2020 were evaluated retrospectively. After exclusion criteria, the study was carried out with 184 stone-free cases...

This study aimed to compare the effects of radial extracorporeal shockwave therapy (rESWT) to the effects of high-intensity laser therapy (HILT) in the treatment of individuals with plantar fasciitis. Thirty-two individuals with unilateral plantar fasciitis were randomized into two groups: rESWT and HILT. In each group, the individuals underwent the intervention two sessions per week, for three weeks. Outcome measures included morning pain, resting pain, pain at 80 newtons (N) pressure, skin blood flow and temperature, plantar fascia (PF) and flexor digitorum brevis (FDB) thickness, and Foot Function Index (FFI)...

Excimer laser coronary angioplasty (ELCA) vaporizes plaques and thrombi, provides better microcirculation, and reduces peripheral embolism when treating acute coronary syndrome. Studies on the efficacy of ELCA for long onset-to-balloon time ST-segment elevation myocardial infarction (STEMI) are limited. Thus, we aimed to examine the efficacy of ELCA for STEMI using the onset-to-balloon time (OBT). A total of 319 patients with STEMI who underwent percutaneous coronary intervention from 2009 to 2012 and from 2015 to 2019 were enrolled...

Laser has revolutionized the medical field, broadening the diagnostic and therapeutic spectrum, with diode (630-980 nm) and Nd:YAG (1064 nm) lasers being the common choices in ablation procedures. Laser ablation in pilonidal sinus disease is a new minimally invasive technique with good treatment efficacy, low post-op morbidity, and shorter recovery periods following employment. This review study aimed to provide information on the use of lasers in pilonidal sinus disease and their effectiveness compared to other conventional methods...

The transient apical pressure side effect is an important safety consideration for Er:YAG laser-activated irrigation (LAI). Therefore, this study aimed to measure the transient apical peak pressure (TAPP) of LAI under different laser settings in various tooth models using a high-frequency sensor system. Tooth models with different pulp chamber structures, apical diameters, and curvatures were prepared using transparent resin and filled with deionised water. The Er:YAG laser fibre was placed 3 mm from the root canal orifice...

Photothermal therapy based on plasmonic gold nanoparticles is considered a promising approach for cancer treatment. Here, we investigate the in vitro photothermal effect of 30-nm gold nanoparticles, optically excited with a 532-nm continuous laser, on the U87MG malignant glioblastoma cells, and demonstrate the role of nanoparticle concentration and exposure power density in achieving its optimum performance. Laser-induced collective oscillation of electrons in plasmonic gold nanoparticles is employed to generate localized heat to denature tumor cells...

Neuropathic pain (NP) following spinal cord injury (SCI) often lasts for a long time and causes a range of problems that reduce the quality of life. Current treatments are not generally effective; however, photobiomodulation therapy (PBMT) has made some progress in this area. Due to the novelty of this treatment, standard therapeutic protocols have not yet been agreed upon. In the present study, we compare the analgesic effect of two PBMT protocols (2 and 4 weeks of radiation). A total of thirty-two adult male Wistar rats were divided into four groups: control, SCI, 2 W PBMT, and 4 W PBMT...

This study aims to investigate the efficacy of office-based potassium-titanyl-phosphate (KTP) 532-nm laser in the management of recurrent laryngeal papillomatosis (RLP) following other treatments. A retrospective assessment was performed on 55 patients in 259 cases of RLP between 2012 and 2019. Derkay scores were obtained for all patients who underwent 532-nm KTP laser procedure (6 W of power with a continuous output mode) prior to treatment and after treatment. Analysis of parameters is based on the distribution characteristics of data...

The study aimed to evaluate the relation between microcirculation of the genian region using laser Doppler flowmetry and oral mucositis (OM) and pain in individuals undergoing antineoplastic therapy. A case-control clinical study was conducted with the participants divided into three groups: chemotherapy (CTG), radiation therapy and chemotherapy group (RCTG), and control group (CG). Pain was assessed by visual analog scale; OM was classified by oral mucositis assessment and WHO scales. The blood flow was assessed by laser Doppler flowmetry...

Treatment of skin diseases is important yet challenging. One of the most common skin diseases in women is melasma, which features acquired facial hyperpigmentation. We studied the effect of cold atmospheric nitrogen plasma on this disease. To characterize the nitrogen plasma, we obtained the relative intensity of the species and the plasma temperature and skin temperature during processing at different input powers and gas flows. Patients complaining of melasma were treated with hydroquinone on both sides of the face, and one side was randomly selected for additional nitrogen plasma therapy...

Periodontal disease is one of the most common chronic diseases in the oral cavity that causes tooth loss. Root scaling and leveling cannot eliminate all periodontal pathogens, and the use of antibacterial agents or lasers can increase the efficiency of mechanical methods. The aim of this study was to evaluate and compare the antibacterial activity of cadmium telluride nanocrystals in combination with 940-nm laser diode. Cadmium telluride nanocrystals were prepared by a green route of synthesis in aqueous medium...
