Introduction: Xanthelasma palpebrarum (XP) is the most common of all the xanthomas which presents as asymptomatic, often bilateral, soft, yellow, papules and plaques around the eyelids. Although, the lesions are benign, it is aesthetically upsetting. The surgical laser is the most effective treatment modality to this problem. Aim: To evaluate the efficacy and safety of ultrapulse Carbon dioxide (CO2) laser in XP in Indian patients. Materials and Methods: It is a prospective, interventional study carried out for two years in which 29 patients with 61 XP lesions were part of the study. Ultrapulse CO2 (Fraxis Duo laser; 10,600 nm) laser treatment was done in every patient for a single sitting. Statistical significance was calculated using Chi-square test using Statistical Packages for Social Sciences (SPSS) version 19.0. The p-value of 0.001 was considered statistically significant. Results: A total number of 29 patients with 61 xanthelasma lesions were included in the study, of which 11 were males and 18 were females with an age range of 27-54 years. In the present study XP lesions were completely resolved in majority (54 lesions in 25 patients) of treated patients. No intraoperative complications were observed. Two patients showed hypopigmentation. There was neither scarring nor recurrence seen after six months follow-up. Conclusion: Ultrapulse CO2 laser is a safe and effective option of treatment for xanthelasma. It is considered as less painful procedure with fewer side effects and recurrences in the present study.

Limited mouth opening (LMO) is a frequent complication of systemic sclerosis (SS). Its management is complex and there are limited treatment options. We report four patients with SS and severe LMO [interincisal distance (IID) <30 mm] treated with pulsed carbon dioxide (CO2) laser. Pulsed CO2 laser treatment of the white lips was performed after all patients had signed a written informed consent in the absence of alternative treatment. Treatment was carried out under locoregional anaesthesia using a Sharplan 30C CO2 laser in the Silk Touch® resurfacing mode. One to three laser sessions were performed at intervals of 8-12 months between sessions. Assessments were performed at 3 and 12 months with measurement of the IID using a ruler, calculation of the Mouth Handicap in Systemic Sclerosis (MHISS) scale and global evaluation by the patients. Adverse events were also reported. In all four patients, an improvement in IID occurred 3 months after the first session with a mean gain of +5 mm (range: 2-7). At 12 months, a mean gain of +8.5 mm (range: 7-10) in IID was observed. The MHISS score decreased by a mean of -14 (range: 11-17). All patients showed improvement of lip flexibility or mouth opening, allowing better phonation and mastication and easier dental care. Adverse effects were transient erythema and/or dyschromia. CO2 laser appears to be effective and well tolerated in the improvement of LMO in SS.

Background: Many interventions have been used to treat post-acne scars, with various degrees of efficacy and adverse reactions. Multimodal approach can achieve better results for improving the physical appearance that even if minor may result in significant distress and reduced quality of life. Objective: To compare the efficacy of subcision with fractional carbon dioxide (CO2) laser and subcision with microneedling fractional radiofrequency (RF) in treating post-acne scars and to study their adverse effects. Methods: In this prospective, interventional clinical study, a total of 64 patients with post-acne scars were enrolled. The patients were randomly allocated into two groups of 32 patients each, in which group A was treated with subcision plus fractional carbon dioxide laser (CO2) and group B was treated with subcision plus microneedling fractional radiofrequency (RF) every 6 weeks for a total of four sittings. An objective score was calculated for each patient using the Goodman and Baron scale to evaluate the outcome every visit during treatment and then 3 months after completion of therapy. Results: In group A, the percentage reduction in the mean objective scores was found to be 64%. In group B, the percentage reduction in mean objective scores was found to be 42%. Most of the changes were seen in the boxcar and rolling types of scars. Conclusions: Subcision and fractional CO2 laser were considered superior over subcision with microneedling fractional (RF) technique for the treatment of post-acne scars. Boxcar and rolling types of scars showed a high response to treatment than icepick scars

This study compared the collateral tissue damage and incisional bridging with granulation tissue via histopathological examination following feline onychectomy performed by radiofrequency (RF) and carbon dioxide (CO2) laser. Two cats were euthanized, and their digits were harvested for histopathological evaluation on days 1, 3, and 7 post-onychectomy. Each digit was evaluated for total lesion width, total necrosis width, and degree of edema, hemorrhage, and inflammation. This study found few significant differences in collateral tissue damage between RF and CO2 laser, but more incisional bridging by granulation tissue was noted with RF for feline onychectomies. These results indicate that RF for feline onychectomy is a reasonable alternative to CO2 laser in regard to collateral tissue damage and bridging of the incision by granulation tissue. In addition, RF is not accompanied by the strict safety considerations and initial expense of acquisition of a CO2 laser.

ABSTRACT Aim: The aim of this study was to evaluate the surface/mineral changes on enamel before and after the application of acidulated phosphate fluoride (APF) gel, fluoride enhanced hydroxyapatite gel and propolis in conjunction with carbon-dioxide (CO2) laser. Materials and Methods: Crowns of 40 human maxillary central incisors were collected and were divided into four groups of 10 each: Topical fluoride application only, topical fluoride application followed by CO2 laser irradiation, CO2 laser irradiation followed by topical fluoride application and CO2 laser irradiation before and after topical fluoride application. The 10 crowns in each group was again sectioned into four equal parts of mesio-incisal, disto-incisal, mesio-cervical and disto-cervical sections rendering 40 samples in each group. Each group was again subdivided into four subgroups: Subgroup C - untreated enamel surface (control). Subgroup A - APF gel application, subgroup R - fluoride enhanced hydroxyapatite gel application and subgroup P - propolis application. The surface morphology of the test samples were analyzed by scanning electron microscopy and mineral changes by energy dispersion X-ray spectrophotometer. Results: Total mineral content is maximum in Group 4A (CO2 laser irradiation before and after APF gel application) and calcium/phosphate ratio is highest in Group 4R (CO2 laser irradiation before and after Remin-Pro application). Group 2A (APF gel application followed by CO2 laser irradiation) has the maximum fluoride retention. Conclusion: Laser irradiation of enamel through a topically applied APF gel is effective in the prophylaxis and management of dental caries.

Background: Fractional Carbon Dioxide (CO2) LASER has better efficacy compared to conventional LASER in treating scar tissue such as acne scars, keloids, and striae albae. However, a population with darker skin has a higher risk of side effects, especially in post-inflammatory hyperpigmentation. Purpose: To evaluate the efficacy and side effects of fractional CO2 LASER in new patients with acne scars, keloids, and striae albae in the Dermatovenereology outpatient clinic. Methods: Retrospective analysis was done on 42 medical records of patients who met the inclusion criterion, which was those who have undergone fractional CO2 LASER treatments. The efficacy and side effects of the therapy were identified and analyzed using the Statistical Package for Social Sciences (SPSS) version 17 program. Result: A total of 42.9% of patients underwent fractional CO2 LASER treatments for acne scars, while 31% and 26.1% of patients received treatments for keloids and striae albae, respectively. There was a statistically significant decrease in the degree of acne scar (2.72 ± 0.83), keloid height (2.2 ± 0.405), and striae width (0.39 ± 0.02). The statistically significant side effects were hyperpigmentation (59.5%), crustae (26.2%), erythema ≥ for 4 days (19%), and new acne (19%). Conclusion: Fractional CO2 LASER was effective for treating scar tissue (acne scars, keloids, and striae albae) with a higher incidence of side effects in population with darker skin and post-inflammatory hyperpigmentation.

Co2 Laser Ablation

Twelve eyelid meibomian gland adenomas in dogs were surgically ablated using the carbon dioxide (CO2) laser. The laser site was not sutured. All procedures resulted in complete removal of the adenoma with no recurrences at 6 months. In addition, no dogs developed corneal disease secondary to the procedure, and the cosmetic appearance of the eyelid margins was good at the end of the 6-month study. Based on results of this study, CO2 laser ablation of canine meibomian gland adenomas is an effective alternative to standard surgical removal.

Carbon Dioxide Co2

A new technique using the carbon dioxide (CO2) laser for the treatment of aural hematomas is described. The laser is used to make an incision into the hematoma to allow for evacuation of the blood, and then multiple, small incisions are made over the surface of the hematoma to stimulate adhesions between the tissue layers. The CO2 laser was used in this fashion to treat 10 aural hematomas in eight dogs. Follow-up ranged from 1 to 23 months. Owners evaluated the cosmetic results following CO2 laser surgery as excellent in three ears, good in five ears, and fair in two ears. Hematomas were resolved in all 10 cases, although two cases developed serosanguineous fluid accumulation that required percutaneous drainage in one case and a second laser procedure in the other case.

Laser Vaporisation

The aim of the present study is to evaluate the treatment results of carbon dioxide (CO2) laser vaporisation in the well-defined cohort patients with oral leukoplakia. The group consisted of 20 patients. Before treatment, a clinical photograph and an incisional biopsy were performed in all the cases. Also, post treatment results were documented with clinical photographs. The mean follow-up period was 12 months. 18 out of 20 patients treated for cure (90%) achieved local control after one treatment. The remaining 2 patients required (10%) 2nd and 3rd vaporisations. The rate of malignant transformation after CO2 laser treatment is found to be 2.27% which is comparable to the other studies. CO2 laser vaporisation in the treatment of oral leukoplakia lesions is an excellent procedure in not only preventing the local recurrence and the malignant transformation but also in preventing the post-operative dysfunction. It is a time saving procedure with a negligible intra operative bleeding. The wound healing procedure after CO2 laser is extremely good causing the least post procedure morbidity.

Genitourinary syndrome of menopause (GSM) causes significant symptomatic aggravation that affects the quality of life (QoL). Vulvovaginal atrophy (VVA), the hallmark of GSM, is managed with topical non-hormonal therapy, including moisturizers and lubricants, and topical estrogen application. Patients not responding/being unsatisfied with previous local estrogen therapies are candidates for a noninvasive modality. Carbon dioxide (CO2) laser therapy, especially the fractionated type (FrCO2), has drawn considerable attention over the past two decades as a non-invasive treatment for GSM. This systematic review describes the accumulated evidence from 40 FrCO2 laser studies (3466 participants) in GSM/VVA. MEDLINE, Scopus and Cochrane databases were searched through April 2021. We analyze the effects of FrCO2 laser therapy on symptoms, sexual function, and QoL of patients with GSM/VVA. As shown in this review, FrCO2 laser therapy for GSM shows good efficacy and safety. This modality has the potential to advance female sexual wellness. Patient satisfaction was high in the studies included in this systematic review. However, there is a lack of level I evidence, and more randomized sham-controlled trials are required. Furthermore, several clinical questions, such as the number of sessions required that determine cost-effectiveness, should be addressed. Also, whether FrCO2 laser therapy may exert a synergistic effect with systemic and/or local hormonal/non-hormonal treatments, energy-based devices, and other modalities to treat GMS requires further investigation. Lastly, studies are required to compare FrCO2 laser therapy with other energy-based devices such as erbium:YAG laser and radiofrequency.

Abstract Background The coronavirus disease 2019 (COVID-19) pandemic has resulted in the rapid uptake of telemedicine (TM) for routine cardiovascular care. Objectives To examine the predictors of TM utilization among ambulatory cardiology patients during the COVID-19 pandemic. Methods In this single centre retrospective study, all ambulatory cardiovascular encounters occurring between March 16th - June 19th, 2020 were assessed. Baseline characteristics by visit type (in-person, TM-phone, TM-video) were compared using Chi-square and student t-tests, with statistical significance defined by p value &lt; 0.05. Multivariate logistic regression was used to explore the predictors of TM versus in-person care. Results 8446 patients (86% Non-Hispanic White, 42% female, median age 66.8 +/- 15.2 years) completed an ambulatory cardiovascular visit during the study period. TM-phone (n = 4,981, 61.5%) was the primary mode of ambulatory care followed by TM-video (n = 2693, 33.2%). Non-Hispanic Black race (OR 0.56; 95% CI: 0.35 - 0.94, p-value=0.02), Hispanic ethnicity (OR 0.53; 95% CI: 0.29 - 0.98, p = 0.04), public insurance (Medicaid OR 0.50; 95% CI:0.32 – 0.79, p = 0.003, Medicare OR 0.65; 95% CI: 0.47– 0.89, p = 0.009), zip-code linked median household income (MHI) of &lt;$75,000, age &gt;85 years, and patients with a diagnosis of heart failure were associated with reduced access to TM-video encounters and a higher likelihood of in-person care. Conclusions Significant disparities in TM-video access for ambulatory cardiovascular care exist among the elderly, lower income, as well as Black and Hispanic racial/ethnic groups.
