Fractional CO₂ Laser for Primary Cutaneous Amyloidosis

This randomized, controlled clinical study will evaluate the clinical and ultrastructural effects, efficacy, and safety of fractional CO₂ laser in patients with primary cutaneous amyloidosis. Twenty-two eligible patients will be randomly allocated in a 1:1 ratio to receive either three fractional CO₂ laser sessions at 4-week intervals or no active laser treatment (control group). The primary outcome will be the change in the Amyloidosis Severity Score from baseline to one month after the final laser session, with secondary assessments including dermoscopic findings, transmission electron microscopy findings, pruritus severity, patient satisfaction, and adverse events.

Impact of Preoperative Bowel Preparation on Healing Outcomes in FiLaC

Background: Fistula tract laser closure (FiLaC) has emerged as a sphincter-preserving treatment for anal fistula (AF). However, the optimal role of preoperative bowel preparation (BP) in enhancing postoperative outcomes remains contentious. While some surgeons recommend enemas to empty the rectum, others ignore BP altogether due to concerns about possible contamination from enemas. Current guidelines suggest that the decision to perform BP is at the surgeon's discretion, as it is not definitively linked to healing rates. Objective: This prospective, non-randomized observational cohort study aims to evaluate whether preoperative bowel preparation significantly impacts primary healing rates following FiLaC in patients with anal fistula. Methods: One hundred consecutive patients undergoing FiLaC will be prospectively enrolled and stratified into two cohorts: Group A (BP) and Group B (no BP). Anal fistulas will be classified by Parks classification. The primary outcome is complete clinical healing at three months, defined by the absence of discharge, an epithelialized external opening, and no recurrence. Secondary outcomes include six-month healing rates, recurrence, postoperative pain, quality of life, Wexner continence scores, and complication rates. Multivariate logistic regression will be employed to control for potential confounders, including smoking status, prior seton use, and fistula complexity. Discussion: This study aims to fill the evidence gap regarding the benefits of preoperative BP in FiLaC procedures, improving perioperative protocols to optimize healing outcomes while reducing unnecessary interventions. The findings will provide clinicians with evidence-based guidance on BP strategies.

Evaluating the Effect of Blue m Gel on Healing of Palatal Donor Site Versus Using Diode Laser

A sample size of 40 patients, Group A of 20 patients treated with blue m gel and Group B of 20 patient treated with diode laser were included in this study after free gingival grafts harvested from the hard palate. Participants were assessed for the amount and duration of bleeding, pain duration, and the risk of infection 2, 7,14, 30 days post-operative

Different Laser Frequencies on Neuropathic Outcomes in Patients With Bell's Palsy

this study was done to compare different laser frequencies on neuropathic outcomes in patients with Bell's palsy.

Comparison of Er:YAG Assisted Laser Crown Lengthening Against Surgical Crown Lengthening

Crown lengthening is a clinical procedure that involves reshaping the gingiva, and sometimes bone, in order to expose more of tooth's structure. The procedures is performed for both functional and aesthetic reasons. In certain instances, this procedure is performed to This procedure is commonly performed for both functional and aesthetic reasons, such as to prepare a tooth for a crown or to enhance the appearance of a smile. Traditional crown lengthening techniques typically involve surgical methods that can be invasive, leading to extended recovery times and postoperative discomfort in this study we compare traditional versus the laser aided crown lengthening to compare the periodontal parameters in both cases.

High-Energy Laser in the Conservative Treatment of Rhizarthrosis

Osteoarthritis (OA) is a degenerative joint disease that can affect the hands and is particularly debilitating when it involves the trapeziometacarpal joint (rhizarthrosis). It causes pain, deformity, limited movement and strength, joint instability, resulting in significant limitations in daily activities.Many conservative treatments, such as medications, therapeutic exercises, physical therapy, and orthoses, are effective for managing hand OA. For patients who do not respond to conservative treatments, surgical intervention will be necessary.

Photobiomodulation, Cryotherapy Combined With Compression, and Massage for Recovery

Skeletal muscle fatigue is an inevitable phenomenon in the training and competition routine for many crossfit athletes, which can impair their physical performance and predispose them to musculoskeletal injuries. Thus, strategies and/or therapies that minimize fatigue and accelerate muscle recovery are extremely relevant for everyone involved with sport. The aim of the present study is to investigate and compare the effects of photobiomodulation, cryotherapy combined with compression, and massage as isolated therapies for muscle recovery after a protocol of induced muscle damage and fatigue in Crossfit athletes. This is a randomized, double-blind, crossover, sham-controlled clinical trial. Will be recruited 60 male participants, adults, aged between 18 and 40 years, Crossfit practitioners. They will be randomly allocated into 3 groups of 20 participants per therapy, each crossed between effective and sham every 15 days. The primary outcome will be muscle performance in functional test (free squat) and knee extensor torque in maximal voluntary isometric contraction (MVIC). Secondary outcomes will be evaluated by the levels of muscle damage via creatine phosphokinase (CPK) and inflammatory process via blood C-reactive protein (CRP); and delayed onset muscle pain via numerical verbal scale (0-10). All outcomes will be evaluated at baseline, 24h and 48h after induction of muscle damage and fatigue. Data will be analyzed and compared intra and inter groups with a significance level of 5%.

Erbium-doped Yttrium Aluminum Garnet (Er:YAG) Laser vs Conventional Ceramic Bracket Debonding: A Split-Mouth Clinical Trial

This randomized split-mouth clinical trial evaluates enamel surface preservation, pulpal temperature variation, and patient-reported discomfort during ceramic orthodontic bracket removal using two Erbium-doped yttrium aluminum garnet (Er:YAG) laser parameter settings compared to conventional mechanical debonding. Pulpal temperature is monitored in real time using a thermocouple device. Enamel integrity is assessed using the Adhesive Remnant Index (ARI) under 40× magnification. The study aims to determine optimal laser parameters ensuring safe and conservative bracket removal.

Comparative Effectiveness of Long-Pulsed 1064-nm Nd:YAG and Fractional CO₂ Laser in Skin Rejuvenation

Skin rejuvenation is an effort to improve skin condition from the signs of skin aging. Skin aging is a complex biological process influenced by intrinsic and extrinsic factors, leading to changes in the epidermis and dermis, including decreased collagen characterized by dermal thinning, as well as alterations in skin appearance such as laxity and wrinkles. Laser therapy is one of the treatment modalities for skin rejuvenation, aiming to induce neocollagenesis and collagen remodeling, resulting in dermal thickening and improvement in skin appearance. Fractional CO₂ laser is an ablative laser considered the gold standard therapy for skin rejuvenation, whereas Long Pulsed (LP) Nd:YAG 1064 nm is a nonablative laser that is also used for skin rejuvenation. To date, there have been no studies evaluating the comparative effectiveness between fractional CO₂ laser and LP Nd:YAG 1064 nm for skin rejuvenation. Therefore, research comparing the effectiveness of fractional CO₂ laser and LP Nd:YAG 1064 nm for skin rejuvenation is needed, assessed based on dermal thickness, skin elasticity, wrinkles, and Global Aesthetic Improvement Scale scores.

Focal Laser Ablation in Prostate Cancer

To assess the effectiveness of MRI-US or PSMA PET/CT-U/S fusion-guided focal laser ablation (FLA) for the treatment of a localized, intermediate-risk prostate cancer in terms of short-term oncological \& functional outcomes.

Evaluating QoL and Postoperative Complications Using TEThA Technique in the Treatment of Tributary Veins

Endovenous laser thermoablation is a well-established alternative for the treatment of tributary veins. We believe that it is possible to improve the techniques described in the literature, aiming not only to allocate the laser fiber within the venous lumen, but mainly to transfix the vessel walls - a technique called TEThA (Transfixing Endovenous Thermal Ablation).
