Long-term efficacy and safety of nonablative monopolar radiofrequency in the treatment of moderate to severe acne vulgaris.

BACKGROUND: Acne vulgaris (AV) is a prevalent skin condition known for its potential to cause scarring and psychological distress, often leading to diminished self-esteem. While topical and oral treatments are commonly prescribed, some patients experience treatment failure, adverse effects, or contraindications to conventional therapies. In response to these challenges, laser and energy-based device therapies have emerged as promising alternatives for individuals who fall into these categories, showing considerable potential in the treatment of AV. OBJECTIVE: This study aimed to evaluate the long-term efficacy and safety of a nonablative monopolar radiofrequency (NMRF) in treatment of moderate to severe AV. METHODS: Twenty-four patients with moderate to severe AV underwent a series of two NMRF treatment sessions, spaced 4 weeks apart. To evaluate treatment outcomes, live in-person lesion counts and measurements of pore size and volume, and sebum production were quantified using Antera® 3D imaging system, and Sebumeter®, respectively. Patients' self-assessment data regarding degree of improvement and facial oiliness were gathered. Dermatology life quality index (DLQI) questionnaire was utilized to assess the impact of AV on their quality of life. All objective and subjective evaluations were conducted at the baseline, 1 month after the first treatment, and during follow-up visits 1, 3, and 6 months after the last treatment sessions. Adverse effects were also recorded during each visit. RESULTS: Twenty out of the 24 subjects completed the study protocol. The mean inflammatory lesion counts significantly reduced by 42.86% and 45.71% from the baseline at 3 (p = 0.027) and 6 months (p = 0.032) after the second treatment. Sebum excretion likewise significantly decreased from baseline by 11.62% (p = 0.012), 13.37% (p < 0.001), and 21.51% (p = 0.004), 1 month after the first treatment, 1 and 6 months after the second treatment, respectively. The pore volume continued to decrease by 35% (p = 0.003) and 41.5% (p < 0.001) at 1 and 6 months following the final treatment, respectively. The DLQI significantly decreased from 10.00 (interquartile range [IQR]: 6.50-15.00) to 2.00 (IQR: 1.00-4.75), corresponding to 80% improvement of the index, 1 month after the last treatment and was sustained up to the last follow-up visit. Patients' self-assessments on degree of improvement and facial oiliness also significantly improved following NMRF treatments. The treatments were well-tolerated without significant adverse effects. CONCLUSION: NMRF appears to be an effective and safe treatment for inflammatory AV, with therapeutic outcomes persisting up to 6 months after two treatment sessions.

A double-blinded, randomized, split-side, vehicle-controlled study of the efficacy of cleanser containing Acanthus ebracteatus Vahl., Suregada multiflora, and Acacia concinna in patients with atopic dermatitis: A pilot study.

BACKGROUND: Barrier repair therapy is the key management approach for both eczematous and non-lesional skin of atopic dermatitis. The use of appropriate cleansers to enhance skin hydration is an adjunctive treatment that increases topical drug penetration. Anti-inflammatory properties of various medicinal plants in tropical Asia have been reported. OBJECTIVE: Investigate the efficacy of herbal cleanser containing a combination of herbal extracts from Acanthus ebracteatus Vahl., Suregada multiflora, and Acacia concinna on seemingly intact skin in patients with atopic dermatitis by measuring improvements in the skin barrier function. METHODS: This 2-week pilot study was a split-side, randomized, double-blinded, vehicle-controlled trial. All patients (n = 30) were asked to use both a cleanser with an active formulation containing the herbal extracts and a vehicle- controlled cleanser on each side of mid-volar forearm. Biophysical assessments including transepidermal water loss (TEWL), skin hydration, skin pH, and skin roughness were performed at baseline and upon study completion. RESULTS: Compared to baseline, the median percentage change in TEWL at the end of the study was significantly greater for the active side 10.4 (-19, 20.7) g/m2h than the control side -13.2 (-28.7, 9.1) g/m2h; p = 0.01. The median percentage change of skin hydration, skin pH, and skin roughness of the active side compared to the control side had no a statistical significance. CONCLUSIONS: This cleanser is beneficial when used as adjunctive therapy. Further studies should evaluate its anti- sinflammatory properties in the remedy or active phase of atopic dermatitis or other inflammatory skin diseases.

A randomized controlled trial to compare the effectiveness and safety of adsorbent lotion containing tapioca starch, spent grain wax, Butyrospermum parkii extract, argania spinosa kernel oil, aloe barbadensis, rosehip oil, and allantoin with a low-potency topical corticosteroid in the treatment of intertrigo.

BACKGROUND: Intertrigo is an inflammatory skin-fold condition. Candida infections may occur concurrently or afterward. Topical corticosteroids may reduce inflammation but exacerbate Candida infections. The treatment is contentious. OBJECTIVE: To evaluate the efficacies and safety of adsorbent lotion containing tapioca starch, spent grain wax, Butyrospermum parkii extract, argania spinosa kernel oil, aloe barbadensis, rosehip oil, and allantoin for the treatment of mild-to-moderate intertrigo, relative to 1% hydrocortisone cream. METHODS: This randomized, double-blinded study enrolled 40 intertrigo patients. Twice daily, 20 patients applied adsorbent lotion while the remainder used 1% hydrocortisone cream. Efficacy evaluation, skin biophysical measurements, skin tolerability, safety, and visual analog scale (VAS) patient-satisfaction scores were evaluated at baseline and Week 2. RESULTS: The adsorbent lotion showed higher complete cure rates for color, partial epidermal loss, papules/pustules/vesicles/patches, dryness, and scaling than the corticosteroid without statistical significance. Adsorbent lotion demonstrated significantly higher reduction in pruritus than the corticosteroid treatment. Reduction of erythema level using Mexameter and VAS patient-satisfaction scores were not statistically different between adsorbent lotion and hydrocortisone cream. No adverse effects or superimposed infections were reported. CONCLUSIONS: The anti-inflammatory efficacies of adsorbent lotion and low-potency steroid were equivalent. The lotion was safe and produced excellent pruritus reduction. Patient satisfaction was high.

Clinical practice guidelines for the diagnosis and management of atopic dermatitis.

Atopic dermatitis (AD), a chronic, relapsing dermatitis, is characterized by dry and pruritus skin in patients with a personal or family history of atopy. It affects up to 20% of children and 1-3% of adults in most countries worldwide, and leads to significant treatment costs and morbidity. These guidelines are developed in accordance with evidence-based publications and expert opinions. Following simple algorithms, the guidelines aim to assist adult and pediatric physicians in the better care of patients with AD. As with other diseases, there have been several diagnosis criteria proposed over time. Nonetheless, the classical Hanifin and Rajka criterion with no pathognomonic laboratory biomarkers is still the most widely used worldwide for the diagnosis of AD. The management of AD must be considered case by case to provide suitable care for each patient. Basic therapy is focused on avoiding specific/unspecific provoking factors and hydrating skin. Topical anti-inflammatory treatments such as glucocorticoids and calcineurin inhibitors are suggested for disease flare, and proactive therapy is best for long-term control. Other therapies, including antimicrobial agents, systemic antihistamines, systemic anti-inflammatory agents, immunotherapy, phototherapy, and psychotherapy, are reviewed in these guidelines. Crisaborole, a new topical phosphodiesterase 4 inhibitor, can be used twice daily in AD patients over three months old. Dupilumab, a biological drug for patients with moderate-to-severe AD, may be considered in patients with no improvement from other systemic treatments.

Relationship Between Depression and Quality of Life Among Vitiligo Patients: A Self-assessment Questionnaire-based Study.

BACKGROUND: Vitiligo is a common chronic autoimmune disease that is characterized by progressive loss of skin color due to melanocyte destruction. In addition to the physical effects of vitiligo, this condition exerts adverse psychological effects and causes social stigmatization. Earlier studies reported that individuals with vitiligo suffer from poor quality of life (QoL), but data about the QoL of Thai vitiligo patients is scarce. OBJECTIVE: This study aimed to investigate the QoL and prevalence of depression in Thai vitiligo patients, association between QoL and depression, and factors associated with QoL and depression among Thai people with vitiligo. METHODS: This cross-sectional self-assessment questionnaire-based study was conducted at the phototherapy and vitiligo clinics of the Department of Dermatology, Faculty of Medicine Siriraj Hospital, Mahidol University (Bangkok, Thailand). QoL was assessed using the Dermatology Life Quality Index (DLQI) questionnaire, and depression was evaluated via the Patient Health Questionnaire (PHQ-9). RESULTS: Among the 104 vitiligo patients that were recruited, the mean DLQI score was 7.46, and the prevalence of depression (PHQ-9 ≥9) was 13.5%. Factors significantly associated with a higher mean DLQI score were skin phototype IV compared to phototype III, active disease, new lesions within the last three months, lesions involving upper extremities, and PHQ-9 ≥9 (p<0.05). Moderate correlation was found between DLQI score and PHQ-9 score (Pearson's correlation coefficient: 0.524, p<0.001). Factors significantly associated with depression were working status and developing new lesions within the last three months (p<0.05). Patients with new lesions were 4.12 times more likely to be depressed than those without new lesions (OR: 4.12, 95%CI: 1.20-14.16; p=0.025). CONCLUSION: Developing new lesions, active disease, dark skin phototype (IV), and lesion on upper extremity had significant adverse effects on QoL. Vitiligo patients who were employed and who had new vitiligo lesions are significantly more likely to be depressed.

Relationship between vitamin D and chronic spontaneous urticaria: a systematic review.

BACKGROUND: Vitamin D has been reported to be associated with many allergic diseases. There are a limited number of the studies of vitamin D supplementation in patients with chronic spontaneous urticaria (CSU). This study aims to study the relationship between vitamin D and CSU in terms of serum vitamin D levels, and the outcomes of vitamin D supplementation. METHODS: A literature search of electronic databases for all relevant articles published between 1966 and 2018 was performed. The systematic literature review was done following Preferred Reporting Items for Systematic Reviews and Meta-analysis recommendations. RESULTS: Seventeen eligible studies were included. Fourteen (1321 CSU cases and 6100 controls) were concerned with serum vitamin D levels in CSU patients. Twelve studies showed statistically significant lower serum vitamin D levels in CSU patients than the controls. Vitamin D deficiency was reported more commonly for CSU patients (34.3-89.7%) than controls (0.0-68.9%) in 6 studies. Seven studies concerned with vitamin D supplementation in CSU patients showed disease improvement after high-dosages of vitamin D supplementation. CONCLUSION: CSU patients had significantly lower serum vitamin D levels than the controls in most studies. However, the results did not prove causation, and the mechanisms were not clearly explained. Despite the scarcity of available studies, this systematic review showed that a high dosage of vitamin D supplementation for 4-12 weeks might help to decrease the disease activity in some CSU patients. Well-designed randomized placebo-controlled studies are needed to determine the cut-off levels of vitamin D for supplementation and treatment outcomes.
