RESUMO

BACKGROUND: Melasma is a chronic pigmentary disorder. In this study, an innovative cream combining cysteamine and tranexamic acid (TXA) was assessed. OBJECTIVE: To evaluate the safety, efficacy, and patient satisfaction of a novel nano-formulated cysteamine and TXA combination cream in treating subjects with epidermal melasma. METHODS:   Fifty (50) randomized subjects participated and received cysteamine and TXA combination cream. The cream was applied for 30 minutes daily for a 3-month duration. Treatment effectiveness, safety, patient satisfaction, and adherence were evaluated. RESULTS: A continuous improvement in melasma was observed, with modified Melasma Area and Severity Index (mMASI) scores improving by 40%, 57%, and 63% at 30, 60, and 90 days, respectively. The primary endpoint of a decrease in mMASI scores was met, with 91% of participants experiencing melasma improvement. Patient Satisfaction and Patient Adherence scores indicated satisfaction. Convenience exhibited the strongest correlation with patient adherence.  Conclusion: Nano-formulated cysteamine and TXA combination cream showed significant efficacy in decreasing mMASI score while demonstrating a strong safety profile and patient satisfaction.  J Drugs Dermatol. 2024;23(7):529-537.     doi:10.36849/JDD.7765R1.

RESUMO

BACKGROUND: Visual casts and discoloration are common barriers to sunscreen use in melanin-rich populations. However, photoprotective measures are essential for individuals with all skin types, including darker skin. METHODS: Single-center, 7-day, open-label study of healthy adult females with Fitzpatrick Skin Types (FST) IV to VI and sensitive skin treated with once-daily daily facial moisturizer sun protection factor 35 (DFM SPF35). Subjects completed a cosmetic acceptability questionnaire at days 1 and 7. Photography using VISIA CR was performed at day 7. Adverse events were monitored throughout the study. RESULTS: Thirty-two (32) subjects participated; 31.3% had FST IV, 53.1% V, and 15.6% VI skin. DFM SPF35 was viewed as cosmetically elegant. At day 1, 96.7% of subjects agreed product was easy to apply; 90.0% reported soft skin after product use; 86.7% said it had a lightweight, non-greasy feel and hydrated the skin. At day 7, 93.7% reported no visible white residue on their skin and said the product applied easily/absorbed well. The majority (90.6%) would continue using and would recommend the product; and 87.5% reported the product blended seamlessly into their skin, which agreed with clinical photography. Responses were consistent among subjects with normal, oily, or combination skin. No adverse events were reported. CONCLUSIONS: DFM SPF35 blended well into the skin and was perceived favorably among subjects with SOC after 1 and 7 days of use. Subjects felt it had good cosmetic acceptability without unacceptable white residues or a greasy feeling. Dermatologists need to be versed in products that can be used on a variety of skin types.J Drugs Dermatol. 2024;23(7):515-518.  doi:10.36849/JDD.8223.

RESUMO

Variations in the epidemiology, clinical presentation, and disease course in atopic dermatitis (AD) patients with Skin of Color (SOC) compared with white counterparts have been reported. In this study, we evaluated the capability of a new imaging device (SkinCam) in quantifying skin texture changes in diverse patients, presenting with AD or xerosis, after using a prebiotic skincare routine over 10 weeks.  A total of 39 subjects from diverse racial/ethnic backgrounds, aged 3 to 76 years old, with Fitzpatrick skin phototypes I to VI, presenting with mild AD and moderate to severe xerosis, were enrolled in the study. All subjects used a prebiotic cleanser on its own for 2 weeks, followed by a prebiotic moisturizer in conjunction for an additional 8 weeks. Standardized images of the subjects' legs were taken with SkinCam at several time points (baseline, week 2, and week 10), and analyzed for skin texture parameters. Our results demonstrate that both skin texture irregularity and skin color patterns significantly improve over time with a prebiotic skincare regimen in AD (n=12) and xerosis (n=24) subjects. Interestingly, image analyses showed more improvement over time in xerosis and AD SOC patients (n=18, Fitzpatrick IV-VI). Lastly, skin texture analyses from SkinCam imaging correlated with clinical assessments, showing significant improvement by prebiotic skincare regimen in all subjects by week 10. In summary, our results demonstrate that the SkinCam imaging device has the capability to effectively monitor skin texture parameters over time in both AD and xerosis patients with lightly and darkly pigmented skin. J Drugs Dermatol. 2024;23(7):557-563.  doi:10.36849/JDD.8371.

RESUMO

BACKGROUND: All skin tones need to be protected from the damaging effects of solar radiation. Although mineral sunscreens offer protection, they can have a thick, greasy feel and leave a white cast, particularly on darker skin tones. Tints offset white cast and provide visible light protection; however, patients may prefer a sheer option. Therefore, a multifunctional, sheer, 100% mineral sunscreen moisturizer (MSM) with broad-spectrum SPF 50 was developed to have positive aesthetics and deliver anti-aging and skin health benefits to all skin tones.  Methods: An IRB-approved, 12-week, open-label clinical study was conducted to investigate the efficacy and tolerability of the MSM. Thirty-nine (39) females aged 35 to 60 years with moderate-severe overall facial photodamage and representing all Fitzpatrick skin types (FST) were recruited. Participants applied the MSM to the face and neck in the morning and reapplied per US Food and Drug Administration requirements. Efficacy and tolerability grading, photography, ultrasound imaging, corneometer measurements, and questionnaires were completed at baseline and weeks 4, 8, and 12.  Results: Statistically significant progressive improvements were demonstrated from baseline to week 12. At week 12, 23.4% and 26.5% mean improvements in overall photodamage were seen for FST I-III and FST IV-VI, respectively. Favorable tolerability was shown for both the face and neck. Photography corroborated clinical grading, and ultrasound imaging indicated a trend in skin density improvement. The MSM was well-perceived.  Conclusion: The MSM is an efficacious and well-tolerated product for patients of all skin tones who desire a sheer, 100% mineral sunscreen moisturizer with anti-aging and skin health benefits. J Drugs Dermatol. 2024;23(7):538-544.  doi:10.36849/JDD.8082.

RESUMO

We present a case of a patient with a 10-year history of blue-black macules and patches on the face and an associated history of skin-lightening cream usage. The skin lightening cream contained hydroquinone, which is often associated with exogenous ochronosis (EO). Interestingly, the biopsy did not show characteristic findings of ochronosis, confusing the final diagnosis, however discontinuing the skin-lightening creams halted the progression of the patient's skin lesions supporting a diagnosis of EO. EO presents as asymptomatic hyperpigmentation after using products containing hydroquinone. This condition is most common in Black populations, likely due to the increased use of skin care products and bleaching cream containing hydroquinone in these populations. Topical hydroquinone is FDA-approved to treat melasma, chloasma, freckles, senile lentigines, and hyperpigmentation and is available by prescription only in the US and Canada. However, with the increased use of skin-lightening creams in certain populations, it is important for dermatologists to accurately recognize the clinical features of exogenous ochronosis to differentiate it from similar dermatoses. An earlier diagnosis can prevent the progression to severe presentations with papules and nodules. We summarize the clinical presentations diagnostic features, and treatment pearls, concluding with a discussion of the differential diagnoses.  J Drugs Dermatol. 2024;23(7):567-568.     doi:10.36849/JDD.8248.

RESUMO

BACKGROUND: The delicate periorbital region is susceptible to skin dehydration, wrinkles, and loss of elasticity. Thus, targeted and effective anti-aging interventions are necessary for the periorbital area. AIM: To evaluate the efficacy and safety of a new anti-aging eye cream formulated with the active complex (Yeast/rice fermentation filtrate, N-acetylneuraminic acid, palmityl tripeptide-1, and palmitoyl tetrapeptide-7). METHODS: The cell viability and expressions of key extracellular matrix (ECM) components of the active complex were evaluated using a human skin fibroblast model. In the 12-week clinical trial, skin hydration, elasticity, facial photographs, and collagen density following eye cream application were assessed using Corneometer, Cutometer, VISIA, and ultrasound device, respectively. Dermatologists and participants evaluated clinical efficacy and safety at baseline, and after 4, 8, and 12 weeks. RESULTS: PCR and immunofluorescent analyses revealed that the active complex significantly stimulated fibroblast proliferation (p < 0.05) and markedly promote the synthesis of collagen and elastin. Clinical findings exhibited a substantial enhancement in skin hydration (28.12%), elasticity (18.81%), and collagen production (54.99%) following 12 weeks of eye cream application. Dermatological evaluations and participants' assessments reported a significant improvement in skin moisture, roughness, elasticity, as well as fine lines and wrinkles by week 8. CONCLUSION: The new anti-aging eye cream, enriched with the active complex, demonstrates comprehensive rejuvenating effects, effectively addressing aging concerns in the periorbital area, coupled with a high safety profile.

RESUMO

BACKGROUND: Evaluating cleansers and moisturizers provides important information to guide clinicians in the recommendation of these products. This project was performed to visualize skin hydration via heatmap after the use of a gentle skin cleanser (GSC) and moisturizing lotion (ML). METHODS: Half-face, intra-individual open-label study in healthy volunteers. Cleanser was administered in a single application that was then wiped off the face. Moisturizing lotion was applied at least once-daily for one week. Hydration measurements were made at 30 pre-defined points on half of the face, at baseline, and 30 minutes post-application; an additional assessment at week 1 was made for the moisturizing lotion. Heatmaps were generated using Python programming software to interpolate hydration values to colors that were then superimposed onto the volunteer's facial image.  Results: Five subjects completed the cleanser assessments, and 5 subjects completed the 30-minute evaluation for the lotion, with 4 completing the week 1 assessment. There was a visible shift in skin hydration post-GSC application from values approximately in the 12-42 AU (arbitrary unit) range to 30-60 AU at 30 minutes. Similarly, there was a shift in hydration from baseline to 30 minutes that continued to increase through week 1 of ML use. CONCLUSIONS: This innovative heatmap data generation showed a clear, visual change in hydration over time. There was a visible shift in hydration values from baseline to 30 minutes after application of cleanser; hydration also improved after use of moisturizing lotion at 30 minutes and increased after week 1 application.  J Drugs Dermatol. 2024;23(6):463-465.     doi:10.36849/JDD.8221.

RESUMO

BACKGROUND: Clascoterone cream 1% is a topical androgen receptor inhibitor approved to treat acne vulgaris in patients =>12 years of age. This report provides details of patients who developed laboratory signs of hypothalamic-pituitary-adrenal (HPA) axis suppression without clinical signs of adrenal suppression during the clascoterone development program. METHODS: Two open-label, multicenter, Phase 2 trials evaluated HPA axis suppression in patients with moderate-to-severe acne vulgaris. Study 1 (NCT01831960) enrolled cohorts of adults =>18 years of age and adolescents =>12 to <18 years of age. Study 2 (NCT02720627) enrolled adolescents 9 to <12 years of age. Patients applied clascoterone twice daily at maximum-exposure dosages for 14 days. Adrenal suppression was evaluated via cosyntropin stimulation test (CST) at baseline and day 14. Patients with an abnormal CST result (serum cortisol level =<18 µg/dL) had a follow-up CST approximately 4 weeks later. Blood was collected for pharmacokinetic analysis. Other safety assessments included adverse events (AEs), physical examination/vital signs, and electrocardiography. RESULTS: Overall, 5/69 clascoterone-treated patients had an abnormal CST result on day 14, including 1/20 adults, 2/22 patients aged =>12 to <18 years, and 2/27 patients aged 9 to <12 years. All patients had normal cortisol levels at follow-up testing approximately 4 weeks later. No relationship was observed between abnormal CST results and clascoterone plasma concentrations or the amount of study drug applied. No clinically relevant AEs or clinically significant changes in safety measures were observed in patients with adrenal suppression. CONCLUSION: Clascoterone induced laboratory evidence of mild, reversible HPA axis suppression under maximum-use exposure. J Drugs Dermatol. 2024;23(6):433-437.     doi:10.36849/JDD.7997.

RESUMO

Xerosis is experienced by almost everyone at some time in their lives and the foundation of management of dry skin (both consumer- and healthcare professional--directed) rests on the use of moisturizers. Given the wide range of available moisturizers, counseling patients about selecting the optimum moisturizer for their individual situation relies on knowledge of ingredients and formulations. Traditionally, the main focus for many moisturizers centered on the core functional and structural role of ceramides within the epidermal barrier.  However, while a key aspect of transepidermal water loss and other skin barrier functions, components other than ceramides are equally essential in increasing moisturization. The skin's natural moisturizing factors (NMFs) are a complex mixture of water-attracting compounds such as amino acids, urea, lactate, pyrrolidone carboxylic acid (PCA), and electrolytes which play a fundamental role in preserving physiologic function by regulating the water content of the stratum corneum. By facilitating water retention, NMFs contribute significantly to the suppleness, elasticity, normal desquamation, and overall integrity of the skin barrier. Incorporation of NMFs into moisturizers addresses critical deficiencies in the skin's moisture balance that exist in xerotic and atopic skin, and in many skin disorders, mitigating signs and symptoms associated with xerosis and promoting optimal skin health. The biochemical composition of NMFs and the intricate interplay with epidermal homeostasis translate to a central role in moisturizers used for prophylactic and therapeutic management of various dry skin conditions, beyond ceramides alone.

RESUMO

Background: Striae distensae (SD) is a skin condition that frequently causes dermatological consultations and although asymptomatic, it may can cause itch and burning sensation. Green tea extract contains polyphenol, including flavanol, flavandiol, flavonoid, phenolic acid, amino acids and minerals which play a role in the repair of stretch marks through anti-inflammatory mechanism, increase collagen production, fibroblast proliferation, and skin hydration. Objective: To determine the efficacy of green tea extract cream on striae distensae. Methods: This is a pre-experimental clinical trial with a pretest-posttest design on 36 subjects with striae distensae. Diagnosis establishes through history taking and clinical evaluation. Imam Nelva Alviera (INA) score was used as SD severity before and after the application of the 3% green tea extract cream carried out at weeks 0, 2, 4, 6, and 8. Side effects and subjects' satisfaction were also recorded. Cochran test was carried out to see the difference before and after treatment, with a p-value <0.05 considered significant. Results: Majority of study subjects were 18-25 years (77.8%), had history of pregnancy (75%), had a history of menarche at the age of 12 years (27.8%) and all subjects had striae alba. There was significant decrement in INA score for striae distensae (p<0.001) after eight weeks administration of 3% green tea extract cream. Clinical improvement and no side effects were also noted. All subjects were satisfied. Conclusions: The use of 3% green tea extract cream can improve the appearance of SD.

RESUMO

INTRODUCTION: Capecitabine has been widely prescribed to treat various cancers. The hand foot syndrome (HFS) is the most troublesome adverse effect. Urea cream has been pre-emptively co-prescribed, even though its efficacy is doubtful. Aloe vera gel with urea cream might potentiate each other. This trial was intended to prove the efficacy of this combination. MATERIALS AND METHODS: The investigators conducted a randomized single-blinded phase II study. The participants were randomized 1:1 to receive the combination of aloe vera gel and 10% urea cream (n = 30), the experimental A+U arm and 10% urea cream alone (n = 31), the U arm. The sample size was calculated to have 90% power to show the significant 20% reduction in the incidence of HFS grade 2-3 of the combination therapy with alpha level = 0.05. Both the CTCAE criteria version 5 and the dermatology life quality index (DLQI) were assessed to determine the severity of HFS and quality of life, respectively. RESULTS: Most of the participants had rectal cancer (A+U: 43.3%; U: 41.9%). In the A+U group, 86.7% had grade 0-1 HFS and 13.3% had grade 2-3 HFS. In the U group, 64.5% had grade 0-1 HFS and 35.5% had grade 2-3 HFS (Mann-Whitney U test, p = 0.045). Grade 2-3 HFS was significantly lower in the combination group. CONCLUSION: Combination of aloe vera gel and 10% urea cream ameliorated the severity of HFS in participants taking capecitabine; however, no significant difference in DLQI between the groups was demonstrated.

RESUMO

INTRODUCTION: Vitiligo is a chronic, autoimmune condition characterized by skin depigmentation caused by inflammatory-mediated melanocyte degradation. Treatment of vitiligo is challenging due to the chronic nature of the condition. Ruxolitinib cream 1.5% was recently approved by the Food and Drug Administration (FDA) as a Janus kinase 1 and 2 inhibitor for use in nonsegmental vitiligo for those 12 years and older. AREAS COVERED: The purpose of this review is to describe the role of ruxolitinib in treating nonsegmental vitiligo.We searched PubMed using search terms nonsegmental vitiligo, jak inhibitor, and ruxolitinib. Clinicaltrials.gov was used to identify clinical trial data including efficacy, pharmacodynamics, pharmacokinetics, safety, and tolerability. EXPERT OPINION: In both phase II and phase III (TRuE-V1 and TRuE-V2) trials, ruxolitinib cream 1.5% improved repigmentation with minimal adverse effects. Topical ruxolitinib is a much needed new vitiligo treatment option.  Real life efficacy may not match that seen in clinical trials if the hurdle of poor adherence to topical treatment is not surmounted.

RESUMO

Herein, we evaluated friction dynamics of human skin treated with polyacrylic acid aqueous solutions or gel creams using a sinusoidal motion friction evaluation system to demonstrate the effect of treatment with polymer aqueous solutions on human skin. A polymer aqueous solution or gel cream was applied to the inner forearms of 10 subjects to evaluate temporal changes in friction force under sinusoidal motion. Water content, skin viscoelasticity, and transepidermal water loss were also simultaneously measured to determine the effects on skin conditions. When human skin was treated with the polymer aqueous solution, the friction coefficient immediately after treatment was 0.69-0.99 and the delay time δ, a normalized parameter of the time difference in the delayed response of friction to the movement of the contact probe divided by the friction time T 0 for one round trip, was 0.171-0.179, which was greater than that of untreated skin. This increase was caused by the swelling and softening of the stratum corneum caused by the penetration of water in the polymer aqueous solution, which increased true contact area between the skin and contact probe. A significant difference was observed in the friction coefficient of the skin immediately after treatment with different polymer aqueous solutions. Among polymers (P1-P4), P4, which has a low-salt resistance and low yield stress, had the lowest friction coefficient because of collapsing of the polymer network structures by shearing and reduced viscosity owing to salts on human skin. The skin treated with a gel cream also exhibited a greater friction coefficient than the untreated skin immediately after treatment and 90 min later. This phenomenon can be caused by the occlusive effect of the oil in the gel cream.

RESUMO

This retrospective study investigates the efficacy of 2 treatment regimens, pregabalin alone versus pregabalin combined with ketamine, amitriptyline, and lidocaine cream, in reducing itch in patients with brachioradial pruritus at a tertiary care center. Electronic medical records of 64 brachioradial pruritus patients seen at the University of Miami Itch Center were analyzed. A significant reduction in itch scores was seen with both treatments, with no significant difference between the groups. A small number of patients experienced adverse effects, including drowsiness and weight gain with pregabalin and skin irritation with ketamine, amitriptyline, and lidocaine cream. Ultimately, our findings underscore the potential of utilizing combined therapy for difficult-to-treat brachioradial pruritus cases and implementing individualized approaches for managing neuropathic pruritus. Further controlled clinical trials are needed to establish optimal treatment protocols.

INTRODUCTION: Melasma, a chronic acquired skin pigmentation disorder, is characterized by the presence of irregular-edged brown to gray-brown patches with a symmetrical distribution, primarily on sun-exposed areas such as the face. Topical hydroquinone (HQ) is the gold standard for melasma treatment but has numerous side effects. This study assesses the effectiveness of topical tranexamic acid (TA) as an alternative for melasma treatment. METHODS: In a double-blind, split-face, randomized controlled trial involving 20 subjects, the effectiveness of 3% TA versus 4% HQ cream was evaluated over 8 weeks. The modified melasma area and severity index (mMASI), melanin index, erythema index, and side effects were assessed. Subjective improvement was measured using the patient global assessment (PtGA). RESULTS: A significant decline in the mMASI score was observed at weeks 4 and 8 in both groups compared to baseline. There were no statistically significant differences in PtGA scores between the 3% TA group and the 4% HQ group. CONCLUSIONS: Topical 3% TA is as effective and safe as 4% HQ for treating melasma in the Indonesian population, with potential advantages in terms of side-effect profiles.

RESUMO

INTRODUCTION: Rosacea is a chronic inflammatory skin condition associated with erythema, inflammation and skin sensitivity. OBJECTIVES: To assess the benefit of a dermocosmetic cream (DC cream) containing Sphingobioma xenophaga extract and soothing agent in adult females with rosacea-associated erythema and sensitive skin. MATERIALS AND METHODS: During phase 1, DC was applied twice daily on the randomized half-face and compared to usual-skincare (USC) for 28 days. During phase 2, DC was applied on the full face twice daily for 56 days. Clinical, instrumental and skin sensitivity assessments were performed at all visits; demodex density (standardized skin surface biopsy (SSSB) method) was performed at baseline and D28, quality of life (QoL) was assessed using the stigmatization questionnaire (SQ), Rosacea Quality of Life index (ROSAQoL) and Dermatology Life Quality Index (DLQI) at baseline and D84. RESULTS: At D28, a significant benefit of DC over USC was observed for erythema, tightness, burning and stinging (all p ≤ 0.05), erythema measured by chromameter (p < 0.01), corneometry and transepidermal water loss (p < 0.0001 and p < 0.05, respectively), skin sensitivity (p < 0.001) and significant reduction of mean demodex density (p < 0.05) on the DC side. At D84, DC significantly (all p < 0.05) improved clinical signs and symptoms on both sides of the face compared to baseline; SQ, ROSAQoL and DLQI scores improved by 40.4%, 25.0% and 55.7%, respectively compared to baseline. Tolerance was excellent. CONCLUSION: DC significantly improved erythema, skin sensitivity, demodex count, QoL and feeling of stigmatization of subjects with rosacea and is very well tolerated.

RESUMO

Dry skin is a common dermatological condition that frequently affects the elderly. A contributing cause to dry skin is a reduced concentration of hyaluronic acid (HA) in both the epidermis and dermis. The effectiveness of moisturizer containing HA as a therapy for dry skin is impacted by its specific molecular weight. Low molecular weight HA (LMWHA) is believed to be more effective in replenishing skin hydration in aging skin compared to High Molecular Weight HA (HMWHA) due to its ability to penetrate the stratum corneum. However, there is a lack of clinical research supporting this claim. A double-blind, randomized controlled trial was conducted on 36 residents of a nursing home in Jakarta. The participants, aged between 60 and 80 years, had been diagnosed with dry skin. Each test subject was administered three distinct, randomized moisturizing lotions (LMWHA, HMWHA, or vehicle), to be topically applied to three separate sites on the leg. Skin capacitance (SCap), transepidermal water loss (TEWL), and specified symptom sum score (SRRC) were measured at weeks 0, 2, and 4. After four weeks of therapy, area that was treated with LMWHA showed greater SCap values compared to the area treated with HMWHA (56.37 AU vs. 52.37 AU, p = 0.004) and vehicle (56.37 AU vs. 49.01 AU, p < 0.001). All groups did not show any significant differences in TEWL and SRRC scores. No side effects were found in all groups. The application of a moisturizer containing LMWHA to the dry skin of elderly resulted in significant improvements in skin hydration compared to moisturizers containing HMWHA and vehicle. Furthermore, these moisturizers demonstrated similar safety in treating dry skin in the elderly. ClinicalTrials.gov Identifier NCT06178367, https://clinicaltrials.gov/study/NCT06178367 .

RESUMO

Second-degree burn, the most common among burn degrees, underscores the importance of timely and proper treatment in influencing prognosis. Nutmeg (Myristica fragrans), renowned for its potent antibacterial and antifungal properties, also serves as an effective antiseptic for open wounds. The aim of this study was to identify the phytochemical constituents of nutmeg essential oil and analyze the wound healing effect of nutmeg cream on second-degree burns in an animal model. An experimental study with a completed randomized design was conducted on Rattus norvegicus strain Wistar rats with second-degree burn. This study had four groups and each group consisting of four rats: B (burn-treated base cream), B+N (burn-treated 3% nutmeg cream), B+SSD (burn-treated silver sulfadiazine (BSS)), and B+N+SSD (burn-treated 3% nutmeg cream and SSD in a 1:1 ratio). The phytochemical analysis of nutmeg essential oil was conducted by gas chromatography and mass spectroscopy (GC-MS). The burn diameter and burn wound healing percentage were measured from day 0 to 18. One-way ANOVA followed by post hoc analysis using the least significant difference (LSD) was employed to analysis the effect. The phytochemical analysis of nutmeg essential oil found that myristicin, terpinene-4-ol, terpinene, safrole and terpinolene were the most abundant putative compounds in nutmeg essential oil. On day 0, the average burn wound diameters were 1.4 cm in all groups and increases were observed in all groups on day 3. The wound diameter decreased until day 18 with the smallest burn wound diameter was found in the B+N group (0.86±0.37 cm), followed by B+SSD (0.93±0.29 cm). The B+SSD group exhibited the highest percentage of burn wound healing (56.80±14.05%), which was significantly different from the base cream (p<0.05). The percentage of burn wound healing in rats given 3% nutmeg cream was 41.88±13.81%, suggesting that nutmeg cream could promote burn wound healing in rats induced by second-degree burns.

RESUMO

BACKGROUND: Psoriasis significantly impacts patients' quality of life (QoL). Dissatisfaction and non-adherence are major barriers associated with topical treatments. A cream based on the polyaphron dispersion (PAD) Technology containing a fixed-dose of calcipotriol (CAL) and betamethasone dipropionate (BDP) was designed for a patient-friendly psoriasis management. The CAL/BDP PAD-cream demonstrated efficacy, convenience, and safety/tolerability in clinical trials. OBJECTIVES: This research assesses the real-world use, perception, satisfaction, and adherence of CAL/BDP PAD-cream among plaque psoriasis patients. METHODS: Between September-November 2023, psoriasis patients from Spain and Germany using or having used CAL/BDP PAD-cream for >2 weeks were recruited via Wefight network to complete a 30-questions online survey. Anonymized results were pooled for descriptive statistical analysis. RESULTS: The survey was completed by 129 patients (mean age: 43 years; 66% females; mean psoriasis duration: 12 years). Most patients (93%) were satisfied with CAL/BDP PAD-cream. The 66% reported high adherence (visual analogue scale 80-100) and 91% preferred CAL/BDP PAD-cream to their previous topical(s). Patients highlighted its ease/convenience of application, tolerability, and lack of itching/burning. CONCLUSIONS: Psoriasis patients treated with CAL/BDP PAD-cream in a real-world setting show high satisfaction, good adherence, and a positive perception of the product, suggesting that favorable outcomes observed in clinical trials translate to real clinical practice.

RESUMO

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.
