Karanfil E, Görgü M. Efficacy and Pain Tolerance of Alexandrite Laser Hair Removal at Different Stages of the Menstrual Cycle. Aesthet Surg J 2024; 44:NP558-NP566. [PMID: 38394336 DOI: 10.1093/asj/sjae044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2023] [Revised: 02/16/2024] [Accepted: 02/16/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Several different parameters play a role in the transition of hair follicles to the anagen phase, with the role of androgens, progesterone, and estrogen hormones and receptors being significant. OBJECTIVES The effectiveness of laser hair removal (LHR) and pain tolerance during procedure were investigated during 3 different phases of the menstrual cycle. METHODS Forty-eight axillae were randomly divided into 3 groups: menstruation, ovulation, and luteal. Three laser sessions were performed on each axilla at a 1-month interval. Blood hormone levels were measured in the patients. An alexandrite laser was applied during LHR sessions. Before each LHR session and 1 month after the third session, hair follicles in 4-cm2 areas in the center of the axillae were counted. Patients self-assessed the pain they felt during the laser application in each session with a visual pain scale. RESULTS The average values for hair counting in the groups were as follows (M, menstruation; O, ovulation; L, luteinization): M0 = 47.6, M1 = 27.4, M2 = 16.1, M3 = 9.9; O0 = 41.8, O1 = 21.1, O2 = 13.8, O3 = 8.6; and L0 = 49.4, L1 = 27.1, L2 = 15.1, L3 = 9.8. The average values on the visual analog scale scores in the groups were: M1 = 3.94, M2 = 3.06, M3 = 1.94; O1 = 3.50, O2 = 3.06, O3 = 1.69; and L1 = 3.63, L2 = 2.50, L3 = 1.56. Statistical analysis was conducted with Tukey post hoc analysis after analysis of variance. CONCLUSIONS The results of LHR are not affected by changes in hormone levels during the menstrual cycle in females. Although not statistically significant, it has been observed that pain tolerance during laser application is lower during the menstruation cycle. LEVEL OF EVIDENCE: 3

The effects of long-pulsed alexandrite laser therapy on facial redness and skin microbiota compositions in rosacea: A prospective, multicentre, single-arm clinical trial. PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE 2024; 40. [PMID: 37890996 DOI: 10.1111/phpp.12921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 09/26/2023] [Accepted: 10/24/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND Rosacea is a chronic skin disorder characterised by abnormal neurovasculature and inflammation in the central region of the face. The efficacy of pulsed-dye laser and intense pulsed light treatments for rosacea have been demonstrated in several clinical trials. However, there is currently no research on the efficacy of long-pulsed alexandrite laser (LPAL) therapy alone for rosacea-related facial redness and its effect on skin microbiota. AIM To evaluate the efficacy of LPAL therapy on facial redness in rosacea and assess changes in skin microbiota composition. METHODS Subjects with rosacea (n = 21, mean age: 39.2 ± 11.3 years) were recruited from two medical institutions and received monthly LPAL treatments (Clarity II™, Lutronic Corp.) for 3 months. At each visit, clinical photographs were taken, and erythema was measured using a spectrometer. At the initial and final visits, the Dermatology Life Quality Index (DLQI) and Skin Sensitivity Questionnaire (SSQ) were evaluated. Skin swabs were obtained at the initial and final visit, and facial microbiome composition was analysed using 16S rRNA amplicon sequencing. RESULTS After three LPAL treatment sessions, the average facial erythema index, measured using Mexameter® decreased significantly from 360.0 ± 96.7 at baseline to 312.0 ± 94.5 at the final visit (p < .05). The DLQI and SSQ showed significant improvement of symptoms. Skin microbiome diversity and relative abundance were altered significantly, particularly in the genera Clostridium, Lawsonella, Bacteroides, and Lactobacillus. CONCLUSIONS LPAL therapy alone showed favourable efficacy for the treatment of facial redness in rosacea, with some impacts on the skin microbiota composition.

Abstract
BACKGROUND Striae gravidarum (SG) is a common pregnancy-related dermatologic problem, for which finding an effective treatment remains a challenge. AIM To evaluate the safety and efficacy of 1540 nm non-ablative fractional laser (Star lux 500) in the treatment of SG in Iranian women and peruse the relationship between clinical improvement rate and patient characteristics as well as clinical features of striae. METHOD A prospective before-after study was conducted on 50 patients with SG who received three monthly sessions of 1540 nm non-ablative fractional laser and were followed for 2 months after the last treatment session. Clinical changes were measured using both provider-rated outcome through before/after pictures represented by final clinical score (from 0 to 5) and patient-reported outcome (patient global assessment or PGA). RESULTS Over the course of the study both final clinical score and PGA increased significantly from week 4 to week 20 (P value: <0.001 and 0.048, respectively). Only modest adverse effects including erythema, edema and hyperpigmentation were noted. CONCLUSION In conclusion, patients with SG of different type (rubra/alba) or maturity may somehow benefit from treatment with NAFL experiencing minimal transient side effects.Therefore, NAFL may be considered a safe and partially effective treatment option for stretch mark of patients with SG.

A randomized split-face comparative study of long-pulsed alexandrite plus low-fluence Nd:YAG laser versus pulsed-dye laser in the treatment of rosacea. Lasers Surg Med 2022; 54:1217-1225. [PMID: 36183378 DOI: 10.1002/lsm.23605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Revised: 09/19/2022] [Accepted: 09/22/2022] [Indexed: 11/11/2022]
Abstract
OBJECTIVES To compare the effectiveness of long-pulsed alexandrite laser (LPAL) with that of pulsed-dye laser (PDL) for rosacea. METHODS This was a single-blind randomized controlled trial on 27 patients who were clinically diagnosed with rosacea. Randomly assigned split face in each patient received four times monthly treatment of LPAL plus low-fluence Nd:YAG with the contralateral side serving as the control treated with PDL. At every visit, the erythema index (EI) was measured with skin analysis systems, and two independent dermatologists evaluated digital photographs for five-point global aesthetic improvement scale (GAIS). RESULTS The EI significantly decreased on both treated sides (LPAL 366.5 ± 101.0 vs. 295.8 ± 90.2, p < 0.001, PDL 369.0 ± 124.3 vs. 302.7 ± 92.1, p < 0.001) 1 month after fourth treatment (visit 5). Also 3 months after the fourth treatment (visit 6), the reduction in the EI was well maintained on both sides (LPAL 360.3 ± 96.8 vs. 282.0 ± 89.2, p < 0.001, PDL 364.3 ± 121.6 vs. 281.6 ± 97.8, p < 0.001). When comparing the improvement in the EI between the two groups, the percentage reduction in the EI on the LPAL-treated side was not inferior to the PDL-treated side (visit 5: LPAL 18.7 ± 15.7% vs. PDL 16.4 ± 12.9%, p = 0.501 and visit 6: LPAL 21.7 ± 13.9% vs. PDL 21.9 ± 15.2%, p = 0.943). The GAIS and patient satisfaction were comparable between the LPAL and PDL sides and did not show any significant difference. No serious adverse events occurred on either of the treated sides. CONCLUSION This study showed that the decrease in EI in the treatment of rosacea was comparable between PDL and LPAL. Therefore, LPAL could be a promising alternative treatment option with good merits for rosacea, considering no consumables are required for device maintenance.

Int Immunopharmacol 2021; 101:108186. [PMID: 34710658 DOI: 10.1016/j.intimp.2021.108186] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 09/19/2021] [Accepted: 09/20/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Alopecia areata (AA) is a chronic disorder and the best treatment regimen for it is unknown. Currently, one of the best documented treatment modalities for AA is topical immunotherapy. AIM To evaluate the safety and efficacy of a novel method (multi-concentration patch test) versus standard protocol for topical immunotherapy. METHODS A prospective randomized clinical trial was conducted on 30 patients with Alopecia areata, half of them received DPCP with a novel method using multi-concentration patch test to determine the optimal initiating concentration of DPCP (case group) and the other half experienced immunotherapy according to the standard protocol (control group). Percentage of hair regrowth after 6 months of treatment and the incidence of drug-related adverse effects were evaluated and compared between the two groups. (IRCT registration code: IRCT20141209020250N5). RESULTS Absolute and relative hair regrowth percentages were reported 25% and 41.49% in case group and 8.2% and 14.21% in control group respectively. Considerable response (more than 75% hair regrowth) was observed in 4 (26.6%) patients in case and 1 (6.6%) patient in control group. The clinical response was initiated about 7 weeks sooner in case compared to the control group (14 versus 7.38 weeks, P: 0.001). Overall, clinical response was higher in patients received new protocol, compared to control group. Moreover, patients who experienced new protocol had a higher level of treatment satisfaction in comparison with patients having standard protocol (P: 0.012). CONCLUSION This study revealed the effectiveness and safety of the novel multi-concentration patch test DPCP therapy for AA and its priority to conventional method, at least in terms of shortened duration of DPCP immunotherapy.
