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.

The laser treatment of carbon dioxide ultra-pulsed and peelings chemical phenol-deep oil crotón (formulas BackerGordon and Litton) have been and remain the most used for the rejuvenation of the skin of the face. This study was conducted to compare the effects of both treatments by histological sections at different periods of the evolution of the same. Biopsies were performed face treaties skin before and retro immediately and 24 hours after the ablations CO2 laser and 24 hours after application of the formula of Litton for chemical peeling deep. Areas in areas near the biopsies were biopsied 12 hours, 24 hours, 1 week, 2 weeks, 2 and 3 months later, in the case of treatment with phenol 24 hours, 48 hours, 72 hours, 1 week, 1 year and 10 years later. The initial biopsies showed that being ablations CO2 laser deeper than the chemical peeling with phenol, a month both had formed an area neocolágeno. But after three months, the comparatively deep phenol chemical peeling (formula Litton) had been an area neocolágeno more compact and wide as that produced by the CO2 laser ultra-pulsed.

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

Acne scars is framed after serious scenes of skin inflammation in high schooler and early grown-up years. A few treatment choices have been utilized for discouraged skin break out scars, for example, punch joining, punch extraction, fractional carbon dioxide (CO2) laser and so on. In addition, Studies demonstrate that laser skin reemerging, for example, CO2 partial can viably treat discouraged skin inflammation scars. Huge advances have been made in the restorative utilization of the laser in the previous couple of decades. Numerous illnesses in the dermatological field are currently signs for laser treatment that meet all requirements for repayment by numerous national medical coverage frameworks. Among laser types, the fractional carbon dioxide (CO2) laser remains a significant framework for the dermatologist

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.

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.
