Background and Objectives: Warts are benign lesions of viral etiology characterized by a hyperkeratotic appearance tending to spread across the skin surface. Various treatments have been proposed to manage this condition, such as acids, imiquimod, photodynamic therapy, cryotherapy, and various lasers. Materials and Methods: In this paper, we describe a combination protocol using CO2 laser prior to Nd:YAG laser for lesions interesting the palmoplantar areas or dye laser for lesions on other skin surfaces in the management of non-facial warts resistant to traditional therapies. In total, 34 patients with 103 warts suffering from wart infection resistant to traditional therapies treated from 1 January 2019 to 1 June 2020 were retrospectively enrolled at the Dermatological Unit of Magna Graecia University (Catanzaro, Italy). Two dermatologists measured clinical results, classifying lesions with complete resolution, partial resolution, or non-responding. Patients at four months follow-up were asked to evaluate their degree of satisfaction with a visual analog scale (VAS). Results: Almost all patients reported the complete resolution of lesions, with no patient reporting scarring. Five patients reported hypopigmentation in the treated areas. The mean satisfaction level was high. Only three patients experienced a relapse of the condition. Conclusions: Using a vascular laser following a CO2 superficial ablation of warts may help reduce the risk of scarring and decrease the incidence of relapses for lesions resistant to traditional therapies. Therefore, more extensive studies will be necessary to confirm the obtained results.
(1) Benign melanoses are a frequent issue in aesthetic dermatology. Solar lentigo, ephelides, café au lait spots, and other melanoses represent a cosmetic issue for a growing number of subjects. The Q-switched 1064/532-nanometer (nm) laser may be considered the gold standard for management of these aesthetic issues. A new generation of Q-switched lasers, capable of concentrating the energy pulse in the spectrum of hundreds of picoseconds, is emerging, promising better results than previous ones. In this paper, we report the use of a Q-switched laser with a picosecond pulse to manage hypermelanoses. (2) Methods: 36 patients seeking melanosis removal were retrospectively enrolled at Magna Graecia University of Catanzaro. Treatment parameters, although variable, were the following: 1064 nm with a pulse duration of 450 picoseconds (ps) for dermic lesions and 532 nm with 370 ps for epidermal lesions. Up to four treatments, with a minimum interval between laser treatments of 30 days, were performed. After the last session, patients’ satisfaction was assessed at a three-month follow up with a Visual Analogue Scale (VAS). Two blinded dermatologists measured the aesthetic outcome using a five-point scale comparing pictures before laser sessions and during follow-up. (3) Results: 36 patients were enrolled; 23 were females (63.9%) and 13 males (36.1%). The mean reported age was 49.2 ± 18.9 years. All participants were assessed with a complete/almost complete melanosis removal at the dermatological evaluation, with a mean VAS score of 9.39 ± 0.90. (4) Conclusions: The Q-switched 1064/532 nm laser may be considered the main weapon in treating benign hypermelanosis. The picosecond pulse seems to guarantee better results than other devices. However, a clinical trial comparing Q-switched nanosecond pulse with picosecond pulse is necessary to confirm this study’s findings.
Tattoo removal is a well-established procedure in dermatology. Lasers represent the gold standard in the management of this condition nowadays. In this study, we report our experience on the use of a Q-switched nanosecond source. A total of 52 patients were consecutively enrolled in performing tattoo removal at Magna Graecia University of Catanzaro and Tor Vergata University of Rome. Black and blue tattoos were treated with a 1064 nm laser, with a pulse duration of 6 ns and a fluence up to 10 J/cm2, while colored tattoos were treated with sessions of 532 nm laser, with a pulse duration of 6 ns and a fluence up to 5 J/cm2. Up to nine treatments with a minimum interval of 8 weeks between each session were performed. A six-month follow-up visit assessed patient satisfaction (Visual Analogue Scale). Overall clinical result was assessed with a clinical evaluation by two blinded dermatologists using a 5-point scale, comparing pictures before treatment and at follow up. A total of 52 patients were included and analyzed: 30 females (57.7%) and 22 males (42.3%). Mean age was 43.7 ± 12.7 years. According to Fitzpatrick’s skin classification, 16 individuals (30.8%) were type II, 15 (28.8%) were type III, and 21 (40.4%) were type IV. Most of the treated tattoos were carried out by professionals. The mean number of sessions required to obtain a result was 4.6 ± 2.5, and the final tattoo removal rate was 60% or higher, with 51.9% of the patients reporting highest satisfaction scores Q-Switched 1064/532 nm laser may be considered today as the gold-standard treatment for tattoo removal. Our results confirm literature findings of the safety and effectiveness of these devices.
Background and objectives: Facial telangiectasias are dilated blood vessels that can represent a cosmetic issue for patients. They may be associated with other conditions, such as rosacea. Laser and light treatments are nowadays becoming a cornerstone in the management of these lesions. Materials and Methods: In total, 68 patients seeking medical treatment for facial telangiectasias were enrolled from 1 March 2019 to 1 March 2020 at the Dermatological Unit of Magna Graecia University (Catanzaro, Italy). A protocol consisting of a 1064 Nd:YAG laser for darker blue telangiectasias and 532 nm Nd:YAG for red lesions followed by intense pulsed light with an optimized spectrum for vascular lesion 3 weeks after the first procedure was proposed. A three-month follow-up visit assessed patient’s satisfaction using a visual analog scale (VAS). Two dermatologists measured clinical results using a 4-point scale, comparing pictures before treatment and at follow-up. Results: A total of 68 patients (32 males and 36 females) completed the study, performing all requested treatments. No severe side effects were reported. Patient satisfaction was very high (8.15 ± 1.05 out of a 10-point VAS scale), as well as dermatologists’ clinical evaluations (2.19 ± 0.74 out of 3). Conclusions: The combination of vascular lasers and Vascular Intense Pulsed Light acting specifically on small blood vessels may help to improve the aesthetic outcome, reducing side effects. A prospective study with a larger number of participants will be necessary to confirm this study’s findings.
Background and Objectives: Hair removal is a common cosmetic problem interesting more and more patients nowadays. Various laser treatments are currently available. Alexandrite and Nd:YAG laser are the most effective procedures in lighter and darker skin phototypes, respectively. Materials and Methods: A total of 40 patients seeking hair removal in one or more body areas with skin phototypes 2–6 was recruited to perform this study. Patients were divided into two groups. One group was treated with the standard Nd:YAG hair removal procedure, while the other group was treated with a new “in motion” Nd:YAG technology. Results and hair removal rates were evaluated six months after the last treatment. Results: Out of 40 patients treated, all patients experienced hair reduction. No statistically significant difference in hair removal was noted between the two groups; however, a statistically significant reduction in pain during the procedure was observed in the group treated with the “in motion” technique. Conclusions: While traditional and “in motion” Nd:YAG techniques have similar result outcomes in hair removal, the “in motion” technology seems to guarantee a better safety profile compared with the traditional technique. A more extensive clinical study will be necessary to confirm our study’s results.
Background and objectives: Hirsutism is characterized by the abnormal presence of hair in women, which occurs in typically male areas. The causes of this symptom can be many; however, it is often associated with PCOS. Among the most effective procedures that can be used for hair removal are lasers such as the Alex laser, Nd: YAG, and IPL. Materials and Methods: This study analyzed a total of 71 patients who were treated for hirsutism caused mainly by PCOS; the remaining cases were idiopathic. The patients were divided into two groups: the first group was treated with laser sources, specifically Alex and Nd: YAG, and the second group underwent treatment with IPL. The results were evaluated six months after the last treatment. Results: Out of 71 treated patients, all patients experienced good or excellent hair reduction with greater efficacy in laser-treated patients. The incidence of side effects was low, particularly in the IPL group. Conclusions: Both laser and IPL are efficient, safe, and tolerable procedures in treating PCOS-related and idiopathic facial hirsutism, and both have been shown to have a low rate of side effects. However, the Alex and Nd: YAG lasers guaranteed better hair removal results. A more extensive clinical study will be necessary to confirm our study’s results.
