Neinaa YMEH, Awara BSES, Shalaby OES, Abd El-Naby NM. Clinical and dermoscopic assessment of ablative carbon dioxide laser versus intradermal heparin sodium in xanthelasma. PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE 2023; 39:648-656. [PMID: 37776005 DOI: 10.1111/phpp.12915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 09/06/2023] [Accepted: 09/19/2023] [Indexed: 10/01/2023]
Abstract
BACKGROUND Ablative carbon dioxide (CO2 ) laser is still a cornerstone in the management of xanthelasma. However, post-laser complications such as post-inflammatory hyperpigmentation or scarring have to be considered. Heparin sodium was recently suggested as an effective therapeutic modality for xanthelasma. OBJECTIVE The aim of this work was to compare the therapeutic value of ablative CO2 laser versus intradermal heparin sodium in xanthelasma. METHODS This study was piloted on 30 xanthelasma patients, whose lesions were randomly categorized into two groups. Group A was managed with CO2 laser ablation (2 sessions scheduled every 4 weeks), whereas Group B was managed with intradermal heparin sodium injections (10 sessions scheduled every week). Pre- and post-treatments evaluations were done both clinically and dermoscopically. RESULTS Significant reduction of xanthelasma lesions was reported in response to both therapeutic interventions. However, the ablative CO2 laser was more significantly effective than intradermal heparin sodium. Interestingly, intradermal injection of heparin sodium was nearly as effective as ablative CO2 laser in early (<2 years duration) grade I and II xanthelasma, with a lower incidence of post-therapy side effects. CONCLUSIONS Intradermal injection of heparin sodium could be suggested as a safe and cost-effective therapeutic technique for early mild grade I and II xanthelasma. Moreover, it could be recommended as a pre-operative management of grade III and IV xanthelasma to reduce the lesions to be easily ablated with CO2 laser.

Abstract
Xanthelasma palpebrarum is the most common type of xanthomatous lesion. Various methods for treating Xanthelasma palpebrarum have been reported. We conducted a systematic review to evaluate the efficacy and associated complications of different treatment methods, and we summarized these findings as a practical review designed to be clinically useful, accessible, and impactful. Methods The PubMed and Embase databases were searched to identify clinical studies that reported on outcomes and complications of different methods of Xanthelasma treatment. The electronic databases were searched from January 1990 to October 2022. Data on study characteristics, lesion clearance, complications, and recurrences were collected. Results Forty-nine articles (including 1329 patients) were reviewed. The studies reported on surgical excision, laser modalities, electrosurgical techniques, chemical peeling, cryotherapy, and intralesional injection. The majority of studies were retrospective (69%) and single-arm (84%). Surgical excision combined with blepharoplasty and skin grafts showed excellent outcomes for large Xanthelasma. CO2 and erbium yttrium aluminum garnet (Er:YAG) were the most commonly studied lasers and showed more than 75% improvement in over 90% and 80% of patients, respectively. Comparative studies reported better efficacy for CO2 laser than both Er:YAG laser and 30%-50% trichloroacetic acid. Dyspigmentation was the most encountered complication. Conclusions Different methods for the treatment of Xanthelasma palpebrarum have been reported in the literature, with moderate to excellent efficacy and safety profiles depending on the size and location of the lesion. Surgery is more appropriate for larger and deeper lesions, whereas laser and electrosurgical techniques can be used in smaller and more superficial contexts. Only a limited number of comparative studies have been conducted, and novel clinical trials are necessary to further augment appropriate treatment selection.

[PMID: 35082932 PMCID: PMC8786555 DOI: 10.1155/2022/8705436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 12/30/2021] [Indexed: 11/21/2022]
Abstract
Purpose To investigate the effect on meibomian gland function of super pulse carbon dioxide (CO2) laser excision in the treatment of eyelid tumors at palpebral margin. Methods 36 patients with 36 eyelid tumor size ≤ 1 cm and within 1 mm to palpebral margin were recruited in this study. Of which, 16 cases with tumors in the upper eyelid and 20 cases in the lower eyelid were involved. The eyelid tumors of all the patients were treated by super pulse CO2 laser with its power density varied between 0.6 and 21.1 W/mm2 and in repeat mode. The laser spot size ranged from 120 to 200 μm. Ocular surface parameters including tear film break-up time (BUT) and meibograde, meibum expressibility, and meibum quality were evaluated at pretherapy, 1 week, 1 month, and 3 months posttherapy in all 36 patients. Result All the patients were satisfied with the therapy. No infective complications and recurrence occurred in any of the 36 patients at the following period. The eyelid wound recovered well with nearly normal appearing after 2 to 3 weeks. The morphology of limbi palpebralis, BUT, meibograde, meibum expressibility, and meibum quality of all the 36 patients showed no significant difference before and after the therapy. Conclusions Super pulse CO2 laser had no effect on meibomian gland function and morphology in the excision of tumors at palpebral margins, which was an efficacy and well-tolerated therapy with lower complications and recurrence.

Abstract
Background: Xanthelasma palpebrarum (XP) is a form of cutaneous xanthoma that presents as collections of yellowish papules or plaques around the eyelids or canthus, affecting patients cosmetically. Objective: This study aimed to compare the efficacy and safety of fractional carbon dioxide (CO2) laser to that of fractional Er:YAG laser for the treatment of XP. Methods: Two centers recruited patients diagnosed with XP of bilaterally symmetrical lesions. The lesion on one side was randomly assigned to be treated with fractional CO2 laser while the lesion on the other side was treated with fractional Er:YAG laser. All subjects received up to five treatments, with a 4-week interval between each treatment. Results: Thirty-nine patients completed the study and a total of 82 lesions were available for final assessment. The percentage of "Excellent Improvement" on third and fourth visit was 60.98% versus 39.02% and 90.24% versus 63.41%, respectively, p < 0.05. In a follow-up for 12 to 25 months, the number of lesions recurred on the side treated with fractional CO2 laser and fractional Er:YAG laser are 9 (22%) and 10 (24%), respectively. Conclusions: In this study, fractional CO2 laser therapy appears superior since a fewer treatments are required for patients to show significant clinical improvement.

Abstract
BACKGROUND Although being a benign lesion, xanthelasma palpebrarum (XP) causes cosmetic concerns. There are numerous therapeutic methods for XP with adverse events for each method. AIMS Evaluate the safety, efficacy, and downtime of fractional CO2 laser (10 600 nm) versus 50% trichloroacetic acid (TCA) in XP therapy. PATIENTS/METHODS Comparative interventional prospective study involved 20 adult patients with XP. Each patient received a split-face therapy where xanthelasma lesions treated with fractional CO2 laser on the one side and TCA 50% on the other side for maximum 5 sessions with 2-week intervals in between. RESULTS Statistically significant improvement in lesion color, thickness, and size by both fractional CO2 and TCA 50%, with nonstatistically significant difference between both therapeutic modalities after treatment, although downtime, number of sessions, and patient's satisfaction were significantly better for fractional CO2 laser. CONCLUSION Fractional CO2 laser (10 600 nm) is ideal for treatment of xanthelasma because it is safe and effective with short downtime, more patient satisfaction, less sessions, and less complications compared with chemical peeling using TCA (50%).

Abstract
Xanthelasma palpebrarum (XP) is the most common form of cutaneous xanthomata, and is important aesthetically, because of its close relation to the eyes, as well as medically for its association with cardiovascular disease (CVD). To provide avant-garde review discussing the various aspects of XP, including its aetio-pathogenesis and various treatment modalities. A structured Pubmed and Medline were searched for relevant articles. The finding of recent research has strongly espoused the link between XP and CVD, and mechanisms have been suggested for its formation. The new technologies have led to a multitude of treatment options for XP. XP is a multi-faceted entity; other than simple treatment of the cosmetic aspect of the disease, one must be cognizant of its cardiovascular implications.

Abstract
Objective: Ultrapulse CO2 laser has been used for several decades for removal of xanthelasma lesions. However, most studies to date have focused on Caucasian patients (skin types I-II). We sought to assess the efficacy and complications of CO2 laser therapy for xanthelasma palpebrarum (XP) in Chinese patients (skin types III-IV). Methods: Data of 38 patients with xanthelasma who received CO2 laser treatment between December 2013 and January 2016 at our hospital were retrospectively analyzed. Patients were followed up for 9 months. Results: Recurrence occurred in 19/38 (50%) patients. Recurrence was significantly more common in patients with multiple lesions (15/24; 62.5%) than in patients with single lesions (4/14; 28.6%). At 3 months after treatment, the complication rate was 63.16%. The complications included hypopigmentation (23/24; 95.8%) and scarring (1/24; 4.2%). In all patients, the hypopigmentation had disappeared by end of the 9-month follow-up. Conclusions: Ultrapulse CO2 laser appears to be capable of completely removing XP in patients with medium skin type III-IV. The most common complication is hypopigmentation, but this resolves with time.

Abstract
Xanthelasmas are localized accumulation of lipid deposits on the eyelids. Lesions are typically asymptomatic and treatment is often sought for cosmetic purposes. Unfortunately, there is paucity of strong evidence in the literature for the effective treatment of normolipidemic xanthelasmas. A literature search using the term “xanthelasma” was carried out in PubMed and Medline databases. Only articles related to treatment were considered and analyzed for their data. Commonly cited treatments include topical trichloroacetic acid, liquid nitrogen cryotherapy, and various lasers including carbon dioxide, Er:YAG, Q-switched Nd:YAG, and pulse dye laser. However, traditional surgical excision has also been used. This article reviews these currently accepted modalities of treatment.

Abstract
BACKGROUND Although not an accepted standard treatment, the 532-nm continuous wave potassium titanyl phosphate (CW-KTP) laser might be a powerful device to treat xanthelasma palpebrarum (XP). OBJECTIVE To determine the safety and efficacy of CW-KTP laser treatment for XP. MATERIALS AND METHODS Between January 2013 and January 2015, 30 consecutive patients with XP were treated with a 532-nm CW-KTP laser (spot size: 0.9 mm, power: 5.0 W, fluence: 36-38 J/cm, pulse width: 46 milliseconds, frequency: 2.0 Hz, passes per session: 3). In a retrospective study design, safety and efficacy data were collected and analyzed. RESULTS Overall, 29/30 (97%) of patients had an excellent cosmetical result. Downtime was 1 week with crusted lesions. Although slight hypopigmentation was common, only 1/30 (3%) patients had hypopigmentation that was more than expected. Recurrences (13/30; 43%) were frequent, so that yearly maintenance therapy was warranted. No major side effects were noticed. CONCLUSION Continuous wave KTP laser therapy is safe and highly effective for XP, although regular follow-up treatments are often necessary to maintain the achieved cosmetic results.

Abstract
Background This paper aims to identify the key fields and their key technical points of oncology by patent analysis. Methodology/Principal Findings Patents of oncology applied from 2006 to 2012 were searched in the Thomson Innovation database. The key fields and their key technical points were determined by analyzing the Derwent Classification (DC) and the International Patent Classification (IPC), respectively. Patent applications in the top ten DC occupied 80% of all the patent applications of oncology, which were the ten fields of oncology to be analyzed. The number of patent applications in these ten fields of oncology was standardized based on patent applications of oncology from 2006 to 2012. For each field, standardization was conducted separately for each of the seven years (2006–2012) and the mean of the seven standardized values was calculated to reflect the relative amount of patent applications in that field; meanwhile, regression analysis using time (year) and the standardized values of patent applications in seven years (2006–2012) was conducted so as to evaluate the trend of patent applications in each field. Two-dimensional quadrant analysis, together with the professional knowledge of oncology, was taken into consideration in determining the key fields of oncology. The fields located in the quadrant with high relative amount or increasing trend of patent applications are identified as key ones. By using the same method, the key technical points in each key field were identified. Altogether 116,820 patents of oncology applied from 2006 to 2012 were retrieved, and four key fields with twenty-nine key technical points were identified, including “natural products and polymers” with nine key technical points, “fermentation industry” with twelve ones, “electrical medical equipment” with four ones, and “diagnosis, surgery” with four ones. Conclusions/Significance The results of this study could provide guidance on the development direction of oncology, and also help researchers broaden innovative ideas and discover new technological opportunities.
