Aesthetic Plast Surg 2024; 48:989-998. [PMID: 38286897 DOI: 10.1007/s00266-023-03828-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 12/18/2023] [Indexed: 01/31/2024]
Abstract
BACKGROUND Hyperpigmented scars, particularly in exposed body areas, can be difficult to conceal and may evoke psychological distress. While the precise causes of scar dyschromia are not fully understood, alterations in melanogenic activity appear to hold more significance than changes in melanocyte quantity. Current treatments encompass laser interventions. However, it is essential to consider their costs and potential complications in relation to their limited proven effectiveness. Fat grafting has gained interest as a scar modulation technique due to its regenerative properties, and its efficacy in reducing scar hyperpigmentation is currently under investigation. METHODS A systematic review and meta-analysis was reported according to PRISMA guidelines. PubMed, Embase, and Cochrane Library databases were accessed. PROSPERO registration number is CRD42023457778. The primary outcome was a change in scar pigmentation after fat grafting. Pigmentation changes after fat grafting were calculated using the standardized mean difference (SMD) between baseline and postoperative scores according to POSAS and VSS scales. Bias assessment was conducted according to the National Institute for Health and Clinical Excellence quality assessment tool. RESULTS A total of 8 articles meeting inclusion and exclusion criteria were identified, involving 323 patients with hyperpigmented scars treated with fat grafting. A significant difference in scar pigmentation was noted after treatment with fat grafting according to observers' ratings, with a SMD of - 1.09 [95% CI: - 1.32; - 0.85], p<0.01. The SMD for patient-reported scar pigmentation after treatment with fat grafting was - 0.99 [96% CI: - 1.31; - 0.66], p<0.01. Four studies provided objective measurements of melanin changes after fat grafting and revealed inconsistent findings compared to subjective observations. CONCLUSIONS Fat grafting shows promise in ameliorating hyperpigmented scars based on subjective assessments, but further corroborating evidence from objective measures is required. LEVEL OF EVIDENCE IV This journal requires that authors assign a level of evidence to each article.

Abstract
Background: The carbon dioxide (CO2) laser is an ablative system that evaporates, remodels, and coagulates tissues, becoming therefore a gold standard piece of equipment for the treatment of dermatological pathologies and esthetic imperfections. Objective: To evaluate the efficacy and safety of CO2 laser treatments in different patients' skin pathologies. Methods: A total of 705 patients with an age range between 18 and 70 years, with phototypes on the Fitzpatrick scale III, IV, V, and VI, were enrolled from October 2021 to May 2022, and were treated using the CO2 laser system. Results: Ninety-six patients were treated with fractional CO2 laser, used for skin rejuvenation and stretch marks. One patient presented reactivation of herpes simplex, 10 postinflammatory hyperpigmentation that resolved after 3 months with depigmenting agents, 6 with persistent erythema. A total of 13 patients with rhinophyma were treated, and no complications were observed; a total of 64 patients with wrinkles were treated. They improved in 6 months. A total of 340 patients were treated for seborrheic keratosis, papulosa nigra dermatosis, fibropapillomas, sebaceous hyperplasias, verruca vulgaris, and condylomata acuminata. One patient presented with a complication hypopigmented macule. A total of 136 patients underwent treatment for laser ablation of intradermal nevi and verrucous epidermal nevi, without complications. A total of 56 patients were treated with keloids and hypertrophic scars. One patient presented with ulceration of a keloid that resolved with the application of clostridiopeptidase A and chloramphenicol after 2 weeks. Conclusions: The use of the CO2 laser in any phototype and race, which are factors with a high incidence in Latin America, provides a safe and effective result for different dermatological pathologies.

Abstract
Scarring is a dire consequence of acne vulgaris. Particularly, atrophic acne scarring is highly prevalent among young adults, and its physical and psychological effects can persist throughout their lives if left untreated. This literature review will analyze various non-energy-based approaches to treating atrophic acne scarring, emphasizing recent advances within the last 5 to 10 years. To accomplish this, we performed a PubMed search for various acne scar treatments such as chemical peels, dermabrasion, microdermabrasion, subcision, microneedling, punch techniques, dermal fillers, and thread lifting. Our findings and analysis show that there is no panacean solution to treating atrophic acne scars, which explains the evolving trend towards developing unique combinatorial treatments. Although a fair comparison of each treatment approach is difficult to achieve due to the studies’ varying sample sizes, strength of evidence, treatment execution, etc, there still remains a level of consensus on what treatments are well suited for particular scar types.

Atan T, Bahar-Ozdemir Y. Efficacy of high-intensity laser therapy in patients with adhesive capsulitis: a sham-controlled randomized controlled trial. Lasers Med Sci 2020; 36:207-217. [PMID: 32808147 DOI: 10.1007/s10103-020-03121-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Accepted: 08/10/2020] [Indexed: 12/28/2022]
Abstract
Adhesive capsulitis is an idiopathic condition characterized by painful shoulder stiffness, impairs quality of life, and causes disability. The purpose of the study is to evaluate the effects of high-intensity laser therapy (HILT) on pain, disability, and quality of life in patients with adhesive capsulitis. The study was designed as a prospective, double-blinded, and sham-controlled randomized trial. Thirty-six patients diagnosed with adhesive capsulitis were randomized into HILT plus therapeutic exercises, sham-laser plus therapeutic exercises, and control-therapeutic exercises only groups. All groups received 25 min of exercises to the shoulder joint supervised by a physiotherapist. Patients in both the HILT and the sham-laser group were blinded to their group randomization. The interventions were performed five times a week for 3 weeks (a total of 15 sessions). The primary outcome measure was the visual analogue scale for pain (Visual Analog Scale for pain (VAS)-pain). The secondary outcome measures were shoulder pain and disability index (SPADI), short-form health survey-36 (SF-36), and range of motion (ROM) of the shoulder joint. Assessments were performed at pre-intervention, post-intervention, and 12-week follow-up by an investigator who was blinded. Thirty-one participants completed the study. HILT plus therapeutic exercises showed significant differences in VAS-pain, SPADI-pain, and SF-36 (subgroups of energy/fatigue, pain, and general health) scores (all P < 0.05). All groups provided comparable improvements in SPADI-disability and ROM of shoulder joint after the interventions and during the follow-up (all P < 0.05). Fifteen sessions of HILT are superior to improve pain and quality of life but not superior in terms of disability or function in patients with adhesive capsulitis. Clinical trial registration number: The study was registered at the US National Institutes of Health ( ClinicalTrials.gov ) (NCT03929276) and available at https://clinicaltrials.gov/ct2/show/NCT03929276?term=tu%C4%9Fba+atan&draw=2&rank=3.

Laser-assisted Lipolysis Burn Safety: Proposed Detailed Parameters with Assessment of Their Efficacy and Safety. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2018; 6:e1934. [PMID: 30534493 PMCID: PMC6250476 DOI: 10.1097/gox.0000000000001934] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Accepted: 07/18/2018] [Indexed: 11/25/2022]
Abstract
Supplemental Digital Content is available in the text. Background: Many recent studies have evaluated the clinical safety and efficacy of therapeutic lasers in laser lipolysis, but without detailed description of the safe and effective parameters. Purpose: To propose a method for adjusting safe and effective parameters for laser lipolysis. Methods: Detailed calculations of the safe and effective laser parameters for fat melting are proposed in the study. Amount of energy delivered in joules was calculated based on data from Havenith research. External skin and internal tissues temperatures during the procedure were kept in a recommended range and monitored for safety and efficacy. Prospective statistical study was designed on a series of 300 patients who underwent laser-assisted lipolysis and /or liposuction using 2 different machine manufacturers, delivering 1,064/1,320 nm. Results: All areas submitted to laser-assisted liposuction in this series have resulted in no clinical thermal burns injury to the skin. There was improvement in the bulk of fats, skin tightening, skin textures, and cellulites. Conclusion: This study is proposing a simple method for calculations of safe and effective laser lipolysis. Skin burn injury could be highly prevented by following up the proposed detailed basic parameters for laser lipolysis treatment.
