The efficacy of low-level laser therapy for the healing of second-degree burn wounds on lower limbs of glucocorticoid-dependent patients
This study was designed to investigate the effect of 630  ~ 650-nm red light on treating second-degree burns on lower limbs of glucocorticoid-dependent patients. Sixty-two glucocorticoid-dependent patients with the second-degree burns on lower limbs were divided into the control group (n = 25) and the observation group (n = 37) according to the treatment sequence and the patients’ willingness. The patients in both groups were conventionally treated with 1% sulfadiazine silver cream dressing, with the only difference that the observation group received an additional 630–650-nm red light irradiation for 20 m...

Photobiomodulation therapy on skeletal muscles exposed to diabetes mellitus: a systematic review of animal studies
AbstractDiabetes-related muscle damage has been overlooked despite its known association with increased morbidity and mortality in DM individuals. PBMT is a recognized alternative to improve skeletal muscle health in other populations, but its effectiveness in DM is still unclear. To address this issue, we reviewed preclinical studies, available in any language and period, in ten sources of information. The methods were previously registered at PROSPERO (CRD42021271041), based on PRISMA recommendations. Studies in murine models of T1DM or T2DM that reported quantitative analyses of skeletal muscles treated with low-level l...

Histological evaluation of mouse tongue incisions after Er:YAG laser surgery with different pulse energies versus after conventional scalpel surgery
ConclusionCompared with surgical procedures using conventional scalpels, those using an Er:YAG laser with appropriate pulse energies can inhibit inflammation in the incisional area and promote incision healing. The use of an Er:YAG laser with appropriate pulse energies can alleviate intraoperative and postoperative pain in the incisional area. (Source: Lasers in Medical Science)

Effect of low-level laser therapy on quadriceps and foot muscle fatigue in children with spastic diplegia: a randomized controlled study
AbstractSpastic diplegia is the most common form of cerebral palsy; children with spastic diplegia are suffering from muscle fatigue and spasticity which lead to decreasing power of muscles, impaired motor control, and many functional abilities. The effect of low-level laser (LLL) has a good result as it improves muscles pain and spasticity and in decreasing lactate levels. Forty children were selected with spastic diplegia and were divided into two groups: A and B. Group A received low-level laser treatment (LLLT) with physiotherapy treatment. Group B got physiotherapy sessions. Pain intensity was assessed by the visual a...

Seven-year corneal densitometry changes after small incision lenticule extraction and femtosecond laser-assisted in situ keratomileusis
This study aims to investigate the 7-year changes in corneal densitometry (CD) after small incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK). Forty-two eyes undergoing SMILE and thirty-one undergoing FS-LASIK were included in this retrospective study. CD was measured preoperatively and at 3 and 7 years postoperatively. Three concentric radial zones (0 –2, 2–6, and 6–10 mm) of three different corneal depths (anterior 120 μm, posterior 60 μm, and central layer) were analyzed. In all three zones of the three corneal layers, no significant difference in CD was found ...

Retro-mode: a newer insight into dry age-related macular degeneration (AMD)
AbstractThe purpose of this study is to study the role of retro-mode (RM) in early detection and to compare it with other preexisting available modalities on multimodal imaging system in dry AMD. A prospective observational cross-sectional study was done between November 2020 and October 2021 which included 409 eyes of 207 patients. For study purpose, eyes were divided into 3 groups according to the size and number of the drusen, viz, group 1: No AMD, group 2: early AMD and group 3: intermediate AMD which was further divided into 2 subgroups, viz, subgroup A: eyes with drusen size 63 –125 μm and subgroup B: eyes with dr...

Efficacy and safety of the combination of tranexamic acid injection and electro-optical synergy (ELOS) versus tranexamic acid injection alone in the treatment of melasma
This study was designed to compare the efficacy and safety of the combination of tranexamic acid  (TA) injection and electro-optical synergy (ELOS) versus TA injection alone in treating melasma. A retrospective study was undertaken for patients with facial epidermal or mixed-type melasma to compare clinical data between 15 patients receiving a combination regimen and 15 patients with TA injec tion only. The study administered TA through intravenous injection to the combination group (twice weekly for 12 weeks) followed by ELOS therapy (once a month for three times). The TA group, on the other hand, received only TA inj...

Nd:YAG laser therapy on postoperative pain, swelling, and trismus after mandibular third molar surgery: a randomized double-blinded clinical study
This study aims to evaluate the effect of Nd:YAG laser therapy (NdLT) on postoperative pain, swelling, and trismus after mandibular third molar (M3) surgery. Three hundred patients were randomly divided into the Nd group (n = 100), medication group (n = 100), and Nd+medication (Nd+m) group (n = 100). The WHARFE classification system was used to assess surgical difficulty. After surgery, the Nd group was irradiated by the Nd:YAG laser in very long-pulsed mode (VLP, pulse duration 1 ms, 20 Hz, 4 W, R21-C3) in 6 regions of the extraction socket with a total energy of 300 J. For the medication group, dexamethasone 0.75 mg and ...

The first meta-analysis research on the effects of endovenous laser ablation combined with sapheno-femoral junction high ligation of the great saphenous vein
AbstractEndovenous laser ablation (EVLA) is a common minimally invasive technique used to treat varicose veins. The most commonly used laser wavelengths for EVLA/EVLT of varicose veins are 810 nm and 1470 nm. The laser pulse frequency is typically set to continuous wave (CW) mode, with a pulse duration of a few milliseconds (ms) delivered in a radial mode. The energy delivered per pulse is typically set between 40 and 120 Joules, with a power setting of 10 to 30 watts and an intensity setting of 40 to 120 J/cm2. The controversy exists regarding the benefits of performing saphenofemoral junction (SFJ) ligation prior to EVLA...

Evaluation of photobiomodulation effect on cesarean-sectioned wound healing: a clinical study
This study reports a clinical examination of PBM under intervention group of 40 patients ranging 18 –40 years old with body mass index (BMI) of 29–36, during post-cesarean surgery to elucidate successful healing of the wounds and scars against conventional methods which considered as control group. Comparison of mean REEDA scores on the third day (p = 0.035), seventh day (p = 0.03), and tenth day (p = 0.02) after delivery exhibits that the two groups benefit a statistically significant difference with each other. For instance, the mean wound healing score in the intervention group was almost half of the me...
