Clinical and Ultrasound Efficacy of Topical Hypertonic Cream (Jovita Osmocell®) in the Treatment of Cellulite: A Prospective, Monocentric, Double-Blind, Placebo-Controlled Study.

Background and Objectives: Cellulite, or edemato-fibro-sclerotic panniculopathy (EFP), is characterized by dermal and hypodermal changes leading to adipose tissue accumulation and compromised venous circulation. This study investigates the efficacy of a hypertonic cream containing concentrated sodium chloride (Jovita Osmocell®) in addressing water retention and structural alterations in adipose tissue, aiming to interrupt the cellulite formation process. Materials and Methods: A 12-week, prospective, monocentric, double-blind, placebo-controlled study enrolled 30 female subjects with grade II or III cellulite. Patients were randomized to receive hypertonic cream or a placebo. Thigh circumference, ultrasound evaluations, and standardized photographs were collected at baseline, intermediate, and endpoint visits. Adverse events were monitored. Results: After 84 days, the hypertonic cream group exhibited a significant reduction in thigh circumference compared to the placebo group (p = 0.0037). B-mode ultrasound examinations revealed significant changes in the parameters studied, such as the thickness of the subcutaneous tissue. No statistically significant changes were noticed in the placebo group. Volunteers reported the investigational product's pleasantness and good anti-cellulite activity, with no reported adverse events. Conclusions: The hypertonic cream demonstrated efficacy in reducing thigh circumference, addressing water retention and structural alterations in adipose tissue. The proposed mechanism involves osmosis, releasing accumulated fluids between fat cells, supporting drainage, and reducing inflammation. This study supports the efficacy and safety of hypertonic sodium chloride emulsions in cellulite treatment and confirms safety and user satisfaction.

An Innovative Dual-Wavelength Laser Technique for Atrophic Acne Scar Management: A Pilot Study.

Background and Objectives: Acne scars are one of the most disturbing and long-term symptoms of acne vulgaris, having a negative impact on a person's physical, emotional, and social well-being. Aim: the purpose of the study was to evaluate the efficacy and post-treatment outcomes of a dual-wavelength system combining the irradiation of two wavelengths at 10,600 nm and 1540 nm in the management of facial atrophic acne scars. Materials and Methods: Four healthy adult volunteers aged 24-53 years were enrolled. The areas treated were the full face (two patients), cheeks (one patient), and forehead (one patient). A dual-wavelength system (1540 nm and 10,600 nm) was used for this study. Patients underwent 2-4 treatment sessions, and the treatments were performed once every 45-90 days. All possible side effects such as burning sensation, dyschromia, mild to moderate post-treatment erythema, bleeding, itching, edema, and crusting were checked. The index to assess edema and erythema was based on a four-point scale (none, mild, moderate, and severe) and was applied before and at 3-month follow-up (3 MFU) after the last treatment session. In addition, a patient assessment was conducted before treatment and at 3 MFU after the last treatment session. Results: For all patients examined, the edema index was mild, while for the erythema index, 3/4 patients experienced moderate and 1/4 patients experienced mild symptoms. The mean patient downtime was 5.8 ± 0.5 days. Concerning the patient assessment, 2/4 subjects showed excellent improvement, 1/4 patients showed good improvement, and 1/4 patients showed slight improvement. As shown by the photographic assessment, a noticeable improvement in skin texture and a substantial reduction in acne scars were observed at the end of treatment. Conclusions: This dual-wavelength laser technology has the potential to be an interesting and safe approach for acne scar treatment, with a low risk of scarring/hypopigmentation and a shorter healing time.

Laser Impacts on Skin Rejuvenation: The Use of a Synergistic Emission of CO2 and 1540 nm Wavelengths.

Background and Objectives: For nearly 15 years, carbon dioxide (CO2) laser has been the gold standard in skin rejuvenation. Aim: The purpose of this study was to assess the efficacy of a new laser device which combines CO2 and 1540 nm wavelengths in wrinkles reduction, using a recently developed scanning unit named the µScan DOT scanner. Materials and Methods: A total of 20 female patients underwent from two to four laser treatment sessions performed once every 45-90 days. Wrinkles reduction was evaluated using the Fitzpatrick Wrinkle Classification System (FWCS). Evaluations of five-point Global Patient's Assessment (PGA) and an Oedema and Erythema index based on a four-point scale were carried out. A careful photographic evaluation was performed to observe the patients' aesthetic improvements. All the assessments were performed before and at 3 months follow up (3 MFU) after the last treatment session. Results: The mean FWCS score significantly (p < 0.01) decreased from 5.45 ± 2.21 at baseline to 3.3 ± 1.78 at 3 MFU after the last treatment session. In total, 8/20 (40%) subjects reported excellent improvement, 7/20 (35%) subjects showed good improvement, 5/20 (25%) subjects showed slight improvement, and 0/20 (0%) subjects showed no improvement. Concerning the Oedema index, 15/20 subjects experienced a mild one, 5/20 subjects experienced a moderate one, and none of 20 experienced a severe one, while for the Erythema index, 1/20 patients experienced mild, 18/20 patients experienced moderate, and only 1/20 patient experienced severe erythema. No severe adverse events were observed. Conclusions: This dual-wavelength laser technique may become a promising new option for safe, nonsurgical improvement for skin rejuvenation with an extremely low risk of scarring or hypopigmentation and shorter healing times.

Combined CO2 and dye laser technique in the treatment of outcomes due to flap necrosis after surgery for basal cell carcinoma on the nose.

BACKGROUND AND OBJECTIVE: Basal cell carcinoma (BCC) is the most frequent cutaneous cancer worldwide, and the nasal area is the most commonly affected region. Skin flaps are usually performed to achieve radical results, but various adverse events often occur. The necrosis of the skin flap is one of the most frequently observed, resulting in scars and anti-aesthetic outcomes. Ablative and non-ablative lasers have been proposed to improve scars resulting from surgical failure and skin flap necrosis. STUDY DESIGN/MATERIALS AND METHODS: This study aims to evaluate a new laser protocol combining ablative CO2 -laser with flashlamp pulsed dye laser for the treatment of nasal scars resulting from the necrosis of flap that occurred after surgery. Twelve patients were enrolled in the study, and a total of five laser sessions were planned, spaced from 14 days to 1 month apart. RESULTS: Seven out of 12 patients underwent all the five laser sessions planned, while 5/12 patients achieved optimal cosmetic results within the fourth session. Eighty percent of the patients reported good/optimal cosmetic results, and no significant side effects were observed during the study. CONCLUSION: Combining fractionated CO2 laser with flashlamp pulsed dye laser represents a new effective modality for treating skin flap necrosis after BBC removal, representing a valid alternative to other surgical procedures.

Combination of Specific Vascular Lasers and Vascular Intense Pulsed Light Improves Facial Telangiectasias and Redness.

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.

Sequential Use of CO2 Laser Prior to Nd:YAG and Dye Laser in the Management of Non-Facial Warts: A Retrospective Study.

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.

Fractional Q-Switched 1064 nm Laser for Treatment of Atrophic Scars in Asian Skin.

Background and Objectives: Asian patients with Fitzpatrick skin type III-IV are a less studied subtype of patients in the medical literature. Q-Switched, 1064 nm neodymium-doped yttrium aluminum garnet (Nd: YAG) laser with a fractionated beam profile (QSF) is a new modality that was reported to be effective in the treatment of scars. This study aims to evaluate the efficacy and safety of QSF Nd: YAG laser in treating scars in Asian patients. Materials and Methods: A total of 29 Subjects were treated with 1064 nm QSF laser. Each patients had three treatments with a fractionated microlens array handpiece every 8 weeks). Efficacy of treatment was evaluated using the Goodman and Baron's quantitative grading scale before and 3 months after the last treatment. Results: All 29 patients treated had significant improvement of acne scars according to Goodman and Baron's Quantitative Global Acne Scarring Grading System. No side effect has been observed except some minor erythematous reactions in three patients. Conclusions: Our results confirm that the 1064 nm QSF Nd: YAG laser is a safe and effective technique for treating scars in Asians.

Comparing Traditional and in Motion Nd:YAG Laser in Hair Removal: A Prospective Study.

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.

Synergistic Sequential Emission of Fractional 10.600 and 1540 nm Lasers for Skin Resurfacing: An Ex Vivo Histological Evaluation.

Background: Fractional ablative and non-ablative lasers are useful treatments for skin rejuvenation. A procedure that provides the sequential application of fractional ablative followed by non-ablative laser treatment may reduce patients' downtime and deliver better cosmetic results than with either laser alone. Objective: The purpose of the current study was to demonstrate the ameliorative and therapeutic effects in skin remodeling of the synergistic use of the two laser wavelengths (fractional ablative CO2 and non-ablative 1540 nm) with three different types of pulse shapes, S-Pulse (SP), D-Pulse (DP) and H-Pulse (HP), through which the CO2 laser can emit, performing an ex vivo histological evaluation. Methods: In this prospective study, ex vivo sheep inner thigh skin was chosen due to its similarity to human skin tissue, and a histological evaluation was performed. Three irradiation conditions, using all of the three CO2 pulse shapes (alone or averaged), were investigated: (1) 10.600 nm alone, the sequential irradiation of the two wavelengths in the same perfectly controlled energy pulses (DOT) for the entire scan area; ((2) 10.600 nm followed immediately by 1540 nm; and (3) 1540 nm followed immediately by 10.600 nm). Results: When comparing ablative to sequential irradiations, the synergy of the two wavelengths did not alter the typical ablative pulse shape of the 10.600 nm laser alone. With the same CO2 pulse shape, the lesion depth did not vary with the synergy of the two wavelengths, while thermal lesion width increased compared to CO2 alone. The ablation rate was achieved, while the total thermal lesion coverage in the scanning area of CO2 - 1540 lasers was greater than when using CO2 alone and then the other sequential irradiation. Conclusions: This study provides important preclinical data for new and early uses of the novel 10.600/1540 nm dual-wavelength non-ablative fractional laser. The synergy of the two wavelengths enhanced all the benefits already available when using CO2 laser systems both in terms of tone strengthening, thanks to a greater shrinking effect, and in terms of stimulation and collagen remodeling thanks to a greater volumetric thermal effect.

A giant epidermal nevus of the face treated with a CO2 and dye laser combination: a case report and literature review.

Epidermal nevi (EN) are cutaneous hamartomas present at birth, usually occurs in the trunk, the face, or the limbs, appearing as a patch of overgrowing skin. They may be small and localized, but they may interest extensive areas of the body. A 20 years old man came to our attention for an EN interesting all the face. The treatment protocol consisted of a session of CO2 laser in order to vaporize thicker areas, followed by a session of dye laser on the area to prevent scarring. This treatment was performed under local anesthesia and sedation in three surgical sessions spaced 3 months from each other. Two sessions of dye laser spaced apart 6 months were performed during follow-up to further improve the esthetic outcome. The patient was followed for 2 years with no recurrence. Although surgery is still considered the gold standard in EN management, it is not always feasible. This novel combination technique can obtain optimal cosmetic results with no relapse within the period of follow up. Although further trials on a more significant number of patients are required, the combination of CO2 and dye laser promises to become a valid therapeutic alternative when treating giant EN of the face.

Fractional CO2 laser-assisted topical rifamycin drug delivery in the treatment of pediatric cutaneous leishmaniasis.

Cutaneous leishmaniasis is challenging to treat. Various drugs have been proposed to manage this condition, with variable results. In this case report, we describe laser-assisted delivery of rifamycin to treat this infection. Two sessions of fractional CO2 laser were performed one month apart. Each was followed by a topical application of rifamycin for three days. Resolution with minimal scarring was obtained, suggesting this technique might be safe and effective in treating cutaneous leishmaniasis.

A new 675-nm laser device in the treatment of acne scars: an observational study.

PURPOSE: Acne scarring represents a common problem that negatively impacts patients' quality of life. Different types of treatments are currently available for this dermatological condition. This study evaluates the efficacy of a new 675-nm laser source system on acne scars with the use of established parameters that guarantee minimum pain and the absence of side effects such as hyperpigmentation, hypopigmentation, and blistering. METHODS: A total of 24 subjects (all women, aged 21-42 years), with Fitzpatrick skin types I-IV and facial acne scars, were treated with three sessions of a 675-nm laser system. Efficacy of treatment was evaluated using the Goodman and Baron's quantitative grading scale before and 3 months after the last treatment. RESULTS: All 24 patients treated with this new 675-nm laser had significant improvement of acne scars according to Goodman and Baron's Quantitative Global Acne Scarring Grading System. No side effect has been observed except some minor erythematous reactions in three patients. CONCLUSION: The 675-nm laser system we used appears to be effective and well-tolerated in patients with acne scars, and it involves a simple post-treatment management.

Topical 5% Imiquimod Sequential to Surgery for HPV-Related Squamous Cell Carcinoma of the Lip.

BACKGROUND: Squamous cell carcinoma (SCC) is one of the most common neoplasms affecting the oral cavity and the face. Its more differentiated forms may be associated with human papilloma virus (HPV) infection. CASE REPORT: In this paper, we report the case of an 86-year-old patient with a well-differentiated SCC of the lower lip associated with HPV treated with surgery with a non-complete histological resolution. Imiquimod 5% cream was applied on the surgical scar once a day for two weeks and then once a week. Two years after SCC removal, no relapse has occurred. CONCLUSIONS: Topical imiquimod may be a safe and effective treatment after surgery in SCC of the oral area to reduce the risk of relapses.

Erythema Multiforme and COVID-19: What Do We Know?

Background: Erythema multiforme (EM) is an acute cutaneous eruption often associated with infections and more rarely with drugs. This review aimed to evaluate the association between erythema multiforme and coronavirus disease 2019 (COVID-19). Methods: A systematic search of PubMed/MEDLINE, Scimago Scopus, and ISI/Web of Science was performed. Original articles, case series, or case reports were evaluated and selected. Results: Fourteen articles were selected, describing a total of 70 patients. EM is a cutaneous eruption rarely occurring in COVID-19 and is, in most cases, associated with a hypersensitivity reaction to the virus. In these cases, EM seems to affect patients younger than 30 years or older than 55 years. Infrequently, some drugs used in the management of COVID-19 may induce EM, especially hydroxychloroquine. The three groups of patients seem to have different clinical characteristics and courses. Conclusions: From these data, it is possible to preliminarily propose that EM or EM-like eruptions linked to COVID-19 might be divided into three types: the virus-related juvenile type (affecting patients <30-year-old), the virus-related older type (affecting patients >55 years), and the drug-induced type. The occurrence of a skin rash does not seem to be related to the severity and clinical course of COVID-19.

Primary Mucosal Melanoma Presenting with a Unilateral Nasal Obstruction of the Left Inferior Turbinate.

We report the case of a primitive nasal melanoma in an 82-year-old patient, showing how this rare malignancy, with non-specific signs and symptoms, can represent a challenging diagnosis for the physician. A 82-year-old Caucasian patient presented for unilateral nasal obstruction and occasional epistaxis. Computerized tomography (CT) and magnetic resonance imaging (MRI) of the facial massif revealed turbinate hypertrophy and a polypoid phlogistic tissue isointense in T1 with an intermediate signal in T2 and Short-TI Inversion Recovery (STIR)-T2, occupying the middle meatus and the anterior upper and lower left meatus with partial obliteration of the ostium and the infundibulum of the maxillary sinus. The Positron emission tomography (PET) exam was negative for metastases. Conservatory surgery in the left anterior video rhinoscopy was performed, allowing a radical 4-cm tumor excision. Histology reported epithelioid cell melanoma, PanK-, CD45-, and PanMelanoma+. Adjuvant radiotherapy was suggested, even considering a complete resection as the result of surgery. No local or systemic relapse was noticed at the 2-month follow-up visit. Although mucosal melanoma is a rare and aggressive malignancy characterized by a poor prognosis, early diagnosis allows a more conservative approach, with little surgical difficulty and no aesthetic effect. Our case raises awareness of the importance of early intervention even in those cases where the clinic symptoms and diagnostic images show uncertain severity.

A novel vehicle for the treatment of psoriasis.

This study evaluates the effectiveness of the topical use of an aerosol foam combination of calcipotriol 50 µg/g plus betamethasone dipropionate 0.5 mg/g (Cal/BD foam, Enstilar®) in adults with moderate plaque psoriasis. A total of 120 male and female adult psoriasis patients (53.3% male) from two Italian dermatological units were enrolled in an 8-week prospective study performed between November 2018 and January 2019. Psoriasis Area and Severity Index (PASI) was evaluated at baseline (T0) and 4 weeks (T4) of daily application, and a further evaluation was carried out 4 weeks after suspension (T8). Furthermore, the Dermatology Life Quality Index (DLQI) was evaluated at baseline and after 4 weeks of treatment (T4). At baseline, patients presented a mean PASI of 7 (7.0 ± 2.1). After 4 weeks (T4) of once-daily application, an important improvement in PASI was observed (1.1 ± 0.3). At Week 4, DLQI was reduced by 5.5 points from baseline (mean: 12 ± 3.1 at T0 vs 6.5 ± 1.8 at T4). Four weeks after suspension (T8), mean PASI was 2.6 ± 1.9, which was stable compared to the previous evaluation; only 8.3% of the treated patients showed worsening of plaque psoriasis. This study suggested that the Cal/BD aerosol foam is an effective topical therapy to treat plaque psoriasis.

Effectiveness of dupilumab for the treatment of nummular eczema phenotype of atopic dermatitis in adults.

Nummular eczema (NE) is currently considered as one of the clinical phenotypes of atopic dermatitis (AD) of the adult. In this multicentre study, 30 adult patients (age ≥ 18 years) affected with nummular-like AD were treated with dupilumab, a monoclonal antibody against the receptor for interleukin(IL)-4 and IL-13. The evaluation of the results after 16 weeks of treatment showed a significant improvement of the disease, as demonstrated by reduction in Eczema Area Severity Score (EASI), visual analogue score (VAS) of pruritus, and Dermatology Life Quality Index (DLQI) scores. Conjunctivitis in one patient was the only side effect. In conclusion, dupilumab seems to be an effective and safe treatment in NE phenotype of AD of the adult.

Cytokine Pathways and Investigational Target Therapies in Hidradenitis Suppurativa.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease affecting areas with a high density of apocrine glands and characterized by subcutaneous nodules that may evolve into fistulas with pus secretion. METHODS: The aim of this review is to investigate all current knowledge on cytokine regulation in the pathogenesis of HS. A systematic literature research using the words "cytokine", "interleukin", "pathway", and "hidradenitis suppurativa" was performed in PubMed/Medline and Scopus/Embase databases. A search of the clinicaltrials.gov website for interventional recruiting and completed trials including the term "hidradenitis suppurativa" was also performed up to August 2020. We will discuss the pathogenetic role of various cytokines in HS and potential therapeutic targets for this debilitating disease. RESULTS: The pathophysiology underlying this complex condition has not been clearly defined. An upregulation of various cytokines, such as tumor necrosis factor alpha (TNF-α), interleukin (IL)-1, IL-17, IL-23, and other molecules seems to be related to this inflammatory condition. Various cells, such as lymphocytes T Helper 1 and 17 and keratinocytes seem to be involved in the genesis of this condition. CONCLUSIONS: Several future studies and clinical trials are necessary in order to have new knowledge about HS and to properly treat this complex condition.

What's new in the treatment of atopic dermatitis?

Atopic dermatitis (AD) is a pruritic, chronic and inflammatory skin disease, with an usual onset in the pediatric age. Several drugs are used in the treatment of this skin disease. Drugs as steroid, calcineurin inhibitors, and moisturizing creams are widely used in the treatment of this disease but often patients are not satisfied with the obtained results. New drugs like dupilumab or crisaborole seem to be a promising option for moderate and severe forms of AD. This article analyzes the newest therapy available today for the treatment of AD.

Q-switched Nd:YAG laser for cosmetic tattoo removal.

Laser is a widely accepted tool for tattoo removal, with standardized treatment protocols. Nevertheless, cosmetic tattoo removal may be challenging, because tattoos are performed in proximity of "sensitive" areas and because the ink used in cosmetic tattoos may contain substances that are not standardized and may modify their color at a high temperature. In this case series, we aim to evaluate the effectiveness of Q-switched (QS) Nd:YAG laser for cosmetic tattoo removal. Our study included 20 patients with cosmetic tattoos of lips, eyebrows, and eyeliners treated with QS Nd:YAG laser. Before treatment, an accurate preoperative assessment was performed, taking into account both patient and tattoo characteristics. Complete tattoo removal was obtained in all the cases and no major complications occurred. Adverse events were mild, mostly represented by erythema. All patients reported a high level of satisfaction. Selective photothermolysis enables complete tattoo removal, even in the case of cosmetic tattoos. However, cosmetic tattoos require a personalized treatment based on an accurate preoperative assessment which takes into account both patient and tattoo characteristics. QS Nd:YAG laser may be considered a good choice in the treatment of cosmetic tattoos, because it enables complete removal with acceptable secondary effects.
