The aim of this study was to investigate the efficacy and safety of the combined treatments of 1064 nm Nd:YAG and 2940 nm Er:YAG in noninvasive lipolysis and skin tightening. Ten females were enrolled, and all women's side of the waist or the lower part of the abdomen were treated. In the first step, the 1064 nm Nd:YAG was used. As a second step, the 2940 nm Er:YAG laser was applied. Each woman was treated four times, once every 2 weeks. The effects were determined by comparative photo documentation, waist circumference measurement, two-dimensional B-mode ultrasonography and low-dose native computer tomography (CT), whereas body fat was monitored with bioelectric impedance. The tissue firmness was measured by ultrasound shear wave elastography. Combined laser treatment significantly reduced waist circumference and total body fat. Ultrasonography has revealed that the treatment considerably decreased fat thickness and improved skin stiffness in the treated region. Subcutaneous fat volume, measured by low-dose CT, displayed a moderate decrease in the waist region. The combined 1064 nm Nd:YAG and 2940 nm Er:YAG laser treatment results in the reduction of fat tissue and tightens the skin as confirmed by objective measurements.}, keywords = {Nd:YAG laser; Er:YAG laser; fat reduction; skin stiffness}, year = {2019}, eissn = {1864-0648}, orcid-numbers = {Besenyi, Zsuzsanna/0000-0001-9115-9620; Urbán, Szabolcs/0000-0001-5463-6811; Pávics, László/0000-0002-7319-1667; Kemény, Lajos/0000-0002-2119-9501} } @article{MTMT:2041766, title = {Treatment of trichostasis spinulosa with 0.5-millisecond pulsed 755-nm alexandrite laser}, url = {https://m2.mtmt.hu/api/publication/2041766}, author = {Badawi, Ashraf Mohamed and Kashmar, M}, doi = {10.1007/s10103-011-0982-2}, journal-iso = {LASER MED SCI}, journal = {LASERS IN MEDICAL SCIENCE}, volume = {26}, unique-id = {2041766}, issn = {0268-8921}, abstract = {Trichostasis spinulosa (TS) is a follicular disorder in which multiple hairs in a keratinous sheath project above the skin surface. Current treatments provide temporary relief and side effects are common. We report the successful treatment of TS in 20 patients using a short-pulsed 755-nm alexandrite laser. The 20 patients (skin types II-V) presented with TS lesions on the tip of their nose. All patients received a single treatment (one to three passes) with the laser with cold air cooling but without anaesthesia or analgesia. Treatment parameters were as follows: pulse duration 0.5 ms, fluence 15-17 J/cm(2), and spot size 5 mm. The entire procedure required less than 5 min to perform. The patients were followed up for 3 months for any adverse effects or recurrence. In all patients the lesions disappeared immediately after treatment with minimal or no pain. Erythema was minimal and lasted 5-20 min in all patients. Patients were very satisfied. The treated areas were still clear 4 to 5 weeks later, and a second treatment was not considered necessary. There were adverse effects other than the erythema and there was no recurrence within the follow-up period of 3 months.

Current treatment modalities, including deep dermal peels; ablative; non-ablative; and fractional laser resurfacing and surgical techniques, are limited in skin types IV through VI due to increased risks of hyper- and hypo-pigmentation. This is especially true when attempting to treat large areas of acne scarring. This study investigates the treatment of atrophic scarring with a non-ablative sub-millisecond-pulsed 1,064 nm Nd:YAG laser in darker skin types. OBJECTIVE: To evaluate the safety and efficacy of a sub-millisecond 1,064 nm Nd:YAG laser for the treatment of atrophic scarring in Fitzpatrick skin types III-VI through retrospective photographic analysis. METHODS: A retrospective analysis was conducted of all patients (n = 22) who received sub-millisecond Nd:YAG laser treatments for atrophic scarring over a 6-month period. Patients had Fitzpatrick skin types III-VI and were treated for the indication of atrophic scarring using the fluence of 14-16 J/cm(2) , pulse duration of 300-500 microseconds and repetition rate of 5-7 Hz. An average of six treatments was performed on each patient approximately 3 weeks apart and the mean follow-up time after the final treatment was 9 months (range of 3-10 months). Blinded photographic assessments were performed by three independent physicians using photos unlabeled for before and after and arranged in non-chronological order. Reviewers were asked to determine before and after photos and the degree of improvement in scarring, textural change, and post-inflammatory hyper-pigmentation (PIH) secondary to the acne or scarring condition. Degree of improvement was graded using a four-point scale: 0 = <25%, 1 = 25-50%, 2 = 51-75%, 3 = 76-100%. RESULTS: Based on blinded photo assessments by three independent reviewers, clinically and statistically significant median improvement of 2 in scarring, 2.3 in texture, and 2 in pigment were observed (one-sample Wilcoxon signed rank test, P < 0.001). Reviewers were highly consistent (inter-reviewer reliability) in identification of before and after photos (kappa of 0.88). CONCLUSIONS: Preliminary data collected in this retrospective study suggest that sub-millisecond 1,064 nm Nd:YAG laser treatment is a safe and effective treatment for atrophic scarring in patients with darker skin types, delivering clinically and statistically significant results with reduced risk of pigment complications and patient discomfort.}, keywords = {Adult; Adolescent; Middle Aged; Humans; Retrospective Studies; Treatment Outcome; Young Adult; Lasers, Solid-State/*therapeutic use; *Skin Pigmentation; Hyperpigmentation/epidemiology/etiology; Cicatrix/*surgery; Acne Vulgaris/*pathology}, year = {2011}, eissn = {1096-9101}, pages = {130-136} } @article{MTMT:1883556, title = {Successful Treatment of Chickenpox Scars With Microdermabrasion and a Nonablative, Submillisecond, 1064-nm Nd:YAG Laser}, url = {https://m2.mtmt.hu/api/publication/1883556}, author = {Badawi, Ashraf Mohamed and Tome, MA and Ayse, Turley and Kemény, Lajos}, journal-iso = {COSMETIC DERMATOL}, journal = {COSMETIC DERMATOLOGY}, volume = {24}, unique-id = {1883556}, issn = {1041-3766}, year = {2011}, pages = {389-394}, orcid-numbers = {Kemény, Lajos/0000-0002-2119-9501} }
