Selected Articles
1. International expert consensus on transdermal drug delivery technologies in dermatology.
A multidisciplinary panel of 25 experts developed recommendations for transdermal drug delivery technologies, particularly fractional lasers and microneedles, using the GRADE framework and a modified Delphi process. Recommendations covered cutaneous malignancies and precancerous lesions, viral warts, inflammatory and autoimmune diseases, and cosmetic indications.
Impact: This paper addresses a major gap between rapidly evolving transdermal technologies and the lack of standardized clinical guidance. Its evidence-graded, expert-consensus framework can improve treatment selection, procedural safety, and reproducibility across dermatologic practice.
Clinical Implications: Dermatologists can use the consensus to guide patient selection, procedural planning, and application of fractional lasers or microneedles for drug delivery across therapeutic and cosmetic indications. Recommendations should be adapted to the quality of evidence and individual patient factors.
Key Findings
- A 25-member multidisciplinary panel reached consensus using a modified Delphi method.
- GRADE was used to assess evidence quality and recommendation strength.
- Recommendations covered malignant and precancerous lesions, viral warts, inflammatory and autoimmune diseases, and cosmetic applications.
Methodological Strengths
- Multidisciplinary international expert participation.
- Integration of systematic literature review, GRADE assessment, and modified Delphi consensus.
Limitations
- The evidence base and recommendation strength may vary substantially across clinical indications.
- Expert consensus cannot substitute for randomized comparative trials for many applications.
Future Directions: Prospective comparative trials should evaluate delivery efficiency, clinical outcomes, adverse events, and cost-effectiveness for specific drug-device combinations. Future updates should incorporate standardized protocols and patient-reported outcomes.
BACKGROUND: Transdermal drug delivery technologies (TDDTs) enhance drug absorption and therapeutic outcomes in dermatology, yet standardized, evidence-based recommendations for their clinical application remain lacking. OBJECTIVE: To provide expert consensus recommendations on the clinical application of TDDTs, with a focus on fractional lasers and microneedles. METHODS: A multidisciplinary panel of 25 experts systematically reviewed current literature and clinical practices. The consensus was developed using the Grading of Recommendations Assessment, Development and Evaluation framework to assess evidence quality and recommendation strength and the modified Delphi method to achieve expert agreement.
2. Multiple Relaxing Short Incisions Significantly Reduce Urethral Fistula After Hypospadias Repair: A Retrospective Cohort Study.
In 316 patients undergoing hypospadias repair, the multiple relaxing short incisions technique was associated with a lower postoperative complication rate and a markedly lower urethral fistula rate than traditional repair. Fistula occurred in 2.16% of the MRSI group versus 8.47% of the traditional group, and multivariable analysis confirmed an independent association with reduced fistula risk.
Impact: The study identifies a technically simple modification associated with a clinically meaningful reduction in urethral fistula, one of the most important complications after hypospadias repair. The favorable cosmetic results support potential adoption in appropriately selected patients with identifiable skin tension.
Clinical Implications: Pediatric surgeons may consider MRSI during hypospadias repair when skin tension is identifiable, particularly to reduce fistula risk. Because the evidence is retrospective, patient selection and surgeon experience remain important.
Key Findings
- The retrospective cohort included 316 patients: 139 treated with MRSI and 177 with traditional repair.
- Urethral fistula occurred in 2.16% of the MRSI group versus 8.47% of the traditional group.
- Multivariable logistic regression showed reduced fistula risk with MRSI (OR 0.081, 95% CI 0.010-0.372; P = 0.005), without a significant difference in penile skin cosmetic scores.
Methodological Strengths
- Relatively large single-study cohort with a contemporaneous comparison group.
- Assessment included multiple surgical complications, cosmetic outcomes, and multivariable regression.
Limitations
- Retrospective, nonrandomized design permits selection bias and residual confounding.
- The technique was evaluated in patients with identifiable skin tension, limiting generalizability to all hypospadias cases.
Future Directions: Prospective multicenter studies with standardized hypospadias severity classification, surgeon training criteria, and long-term functional and cosmetic outcomes should confirm the benefit of MRSI.
PURPOSE: The study aimed to assess the safety, efficacy, and reproducibility of the multiple relaxing short incisions (MRSI) technique in hypospadias repair. METHODS: This retrospective cohort study included 316 patients with hypospadias who used the MRSI technique (group MRSI) or not (group traditional) in hypospadias surgery between September 2020 and September 2023. A comparison was made between the two groups regarding the penis skin cosmetic outcomes and the occurrence of complications such as urethral fistula, wound infection, glans dehiscence, urethral stricture, and urethral diverticulum. RESULTS: Among 316 patients, 139 were assigned into group MRSI while 177 were into group traditional.
3. Topical Corticosteroid Misuse and Awareness of Steroid-Induced Dermatoses Among Adults in Saudi Arabia: A Cross-Sectional Survey.
Among 1,248 adults in Saudi Arabia, 29.0% met the study definition of topical corticosteroid misuse, and 67.5% reported previous use. Social media recommendation was the strongest independent predictor of misuse, while awareness of hidden corticosteroids in cosmetic products remained limited despite generally favorable knowledge of steroid safety.
Impact: This large survey quantifies a substantial, preventable medication-safety problem at the intersection of dermatology, cosmetic use, and social media. The findings identify modifiable targets for counseling, pharmacy regulation, public education, and digital-health interventions.
Clinical Implications: Clinicians should specifically ask about cosmetic and social-media-driven corticosteroid use, facial application, non-prescription access, and use of products with undisclosed ingredients. Counseling should emphasize supervised duration, adverse effects, and appropriate evaluation of suspected steroid-induced dermatoses.
Key Findings
- Among 1,248 participants, 842 (67.5%) had previously used topical corticosteroids and 362 (29.0%) met the definition of misuse.
- Cosmetic use was reported by 178 users (21.1%), while 289 users (34.3%) obtained corticosteroids without a prescription.
- Social media recommendation was the strongest predictor of misuse (aOR 3.48, 95% CI 2.51-4.82; P < 0.001), and awareness of hidden corticosteroids in cosmetic products was only 55.5%.
Methodological Strengths
- Large national sample with a prespecified operational definition of misuse.
- Multivariable logistic regression identified independent demographic and behavioral predictors.
Limitations
- Cross-sectional self-reported data cannot establish temporal or causal relationships.
- Online recruitment may introduce selection bias and may not represent adults with limited internet access.
Future Directions: Interventional studies should test pharmacist-led screening, dermatologist counseling, public campaigns, and social-media content interventions. Regulatory studies should assess non-prescription sales and the prevalence of undisclosed corticosteroids in cosmetic products.
BACKGROUND: Topical corticosteroids are among the most commonly used medications in dermatology and play a pivotal role in the management of inflammatory skin diseases. However, inappropriate use, unsupervised access, and cosmetic misuse may lead to significant adverse effects and steroid-induced dermatoses. Data regarding public awareness, knowledge, and misuse of topical corticosteroids in Saudi Arabia remain limited. METHODS: A national cross-sectional survey was conducted among adults residing in Saudi Arabia between January and March 2026. Data were collected using a structured, self-administered online questionnaire assessing demographic characteristics, topical corticosteroid use, knowledge, awareness of steroid-induced dermatoses, adverse effects, and misuse practices. Topical corticosteroid misuse was defined as the presence of at least one inappropriate behavior, including non-prescription use, cosmetic use, social media-driven use, medication sharing, prolonged unsupervised use, reuse of previous prescriptions, or use for fungal infections.
