1. Slit-like adjusted mathieu versus onlay island flap for narrow urethral plate hypospadias in children: a randomized controlled trial.
In this prospective randomized trial, 93 children with narrow-plate anterior or mid-penile hypospadias completed 24–48 months of follow-up. SLAM repair had fewer complications than onlay island flap repair (10.9% vs 29.8%, p=0.04) and a higher mean HOSE score (15.2 vs 13.1, p<0.001).
Impact: This is a prospective randomized comparison using a validated objective cosmetic and functional score, addressing a technically challenging subgroup of hypospadias patients. The magnitude of the complication reduction and the sustained follow-up provide a clinically actionable basis for further multicenter validation.
Clinical Implications: SLAM may be considered an alternative to onlay island flap repair for selected children with anterior or mid-penile hypospadias and a urethral plate narrower than 8 mm. Adoption should account for surgeon experience, patient anatomy, and confirmation in larger multicenter studies.
Key Findings
- The final analysis included 93 of 100 randomized patients after 24–48 months of follow-up.
- Complications were significantly lower with SLAM than OIF: 10.9% versus 29.8% (p=0.04).
- Mean postoperative HOSE score was significantly higher with SLAM: 15.2±0.9 versus 13.1±1.5 (p<0.001).
Methodological Strengths
- Prospective randomized controlled design with a 24–48-month follow-up period.
- Use of the validated Hypospadias Objective Scoring Evaluation for objective outcome assessment.
Limitations
- Seven randomized patients did not complete follow-up, introducing potential attrition bias.
- The study was conducted at a single institution, which may limit generalizability and reproducibility across surgeons.
Future Directions: Multicenter randomized trials should confirm the findings, include standardized surgeon-training protocols, evaluate patient-reported long-term sexual and urinary outcomes, and assess the durability of cosmetic results into adolescence and adulthood.
PURPOSE: To compare the Slit-like Adjusted Mathieu (SLAM) technique with the inner transverse preputial onlay island flap (OIF) for repair of anterior and mid-penile hypospadias with a narrow urethral plate, with surgical success assessed by postoperative complications and cosmetic outcomes using the Hypospadias Objective Scoring Evaluation (HOSE). METHODS: This prospective randomized controlled study included 100 patients with primary anterior and mid-penile hypospadias and a urethral plate < 8 mm, conducted et al.-Azhar University Hospitals, Cairo, Egypt, from May 2020 to October 2025. Patients were randomly allocated to SLAM repair (Group A, n = 50) or OIF (Group B, n = 50). Outcomes were assessed using validated instruments: Hypospadias Objective Scoring Evaluation (HOSE) during a follow-up period of 24-48 months. RESULTS: A total of 93 patients completed follow-up and were included in the final analysis, comprising 46 patients in the SLAM group and 47 patients in the OIF group.
2. Adverse reactions and complications caused by hyaluronic acid injections in the face: A scoping review.
This PRISMA-ScR-informed review mapped complications reported in 55 studies of facial hyaluronic acid fillers. Bruising, ischemia, and edema were frequently described, while tissue necrosis and embolism were the most serious complications; some reports involved blindness or stroke. The evidence base was dominated by case series and case reports.
Impact: This review consolidates a dispersed safety literature and emphasizes that cosmetic filler complications can include irreversible tissue loss and catastrophic vascular events. It is particularly important for informed consent, injector training, emergency preparedness, and post-market safety surveillance.
Clinical Implications: Clinicians should discuss common reactions and rare catastrophic complications before treatment, use anatomy-informed injection techniques, recognize ischemic signs promptly, and maintain protocols for urgent management of vascular occlusion. The findings also support standardized adverse-event reporting for facial fillers.
Key Findings
- Fifty-five studies were included, and 67.3% were case series or case reports.
- The most frequently reported adverse reactions were bruising (56.4%), ischemia (45.4%), and edema (41.81%).
- The most serious complications were tissue necrosis (29.1%) and tissue embolism (20%), with reports of blindness and stroke.
Methodological Strengths
- Searches covered PubMed, Scopus, and Web of Science and followed PRISMA-ScR reporting principles.
- Study selection involved two independent researchers with cross-checking of data extraction by a third reviewer.
Limitations
- Most included evidence came from case reports and case series, limiting incidence estimates and causal inference.
- The descriptive synthesis could not establish comparative risks by filler product, injection site, dose, or operator technique.
Future Directions: Prospective registries and standardized international reporting systems should quantify complication rates, identify product- and site-specific risk factors, and evaluate the effectiveness of emergency treatments for vascular occlusion and embolic events.
This scoping review identified and mapped the adverse reactions and complications associated with the use of hyaluronic acid (HA) dermal fillers in facial aesthetic procedures. This scoping review was reported according to the PRISMA-ScR. Searches were conducted in three electronic databases (PubMed, Scopus, and Web of Science). Randomized clinical trials, cross-sectional studies, retrospective or prospective cohort studies, case series, or case reports published until 2024 that assessed or reported the use of HA for facial filling in healthy adult patients and documented any adverse reaction or complication were included. Study selection was conducted independently by two researchers. Data extraction was performed on half of the included studies by each reviewer, with cross-checking by a third reviewer. A descriptive analysis of the data was performed, considering the different study designs and the complications and adverse reactions reported. Data were presented in tables and graphs. Fifty-five studies met the eligibility criteria and were included. Most studies were case series and case reports (67.3%). Sample sizes ranged from 1 to 5,000, and participant ages ranged from 18 to 78 years. The most reported adverse reactions among the included studies were bruising (56.4%), ischemia (45.4%), and edema (41.81%), with itching less frequent (3.6%). The most severe complications reported were tissue necrosis (29.1%) and tissue embolism (20%), with some cases leading to blindness or stroke.
3. Examining the safety of dermatological and surgical procedures in patients undergoing systemic isotretinoin therapy: An updated review.
This updated review examined dermatologic, cosmetic, ophthalmic, and surgical procedures performed during or shortly after systemic isotretinoin therapy. Most contemporary studies reported normal wound healing and low rates of hypertrophic or keloid scarring, while evidence supporting a mandatory six-month delay was limited and based largely on older case reports and small case series.
Impact: The review challenges a longstanding practice that may unnecessarily delay acne-scar treatment, laser procedures, and needed surgery. Its conclusions could reduce treatment delays while encouraging individualized risk assessment, especially for patients with darker phototypes or a predisposition to abnormal scarring.
Clinical Implications: A six-month postponement should not automatically be applied to every dermatologic or surgical procedure solely because of isotretinoin exposure. Clinicians should assess procedure depth, anatomical site, skin phototype, scar history, dose and timing of isotretinoin, and the patient’s acne and scarring severity before proceeding.
Key Findings
- Most contemporary studies found normal wound healing during or shortly after isotretinoin therapy.
- The incidence of hypertrophic scarring and keloid formation was generally low across laser, chemical peel, microneedling, and surgical procedures.
- Evidence supporting a mandatory six-month discontinuation period was limited and derived mainly from older low-level reports.
Methodological Strengths
- The review covered a broad range of dermatologic, cosmetic, ophthalmic, and surgical procedures.
- It explicitly identified the historical origin and limited quality of evidence behind the six-month postponement recommendation.
Limitations
- The review methods do not report a formal systematic-review protocol, meta-analysis, or pooled quantitative estimate.
- Evidence remains heterogeneous and prospective data are limited, particularly for darker skin phototypes and patients predisposed to abnormal scarring.
Future Directions: Prospective, procedure-specific studies should stratify patients by skin phototype, scar predisposition, isotretinoin dose and timing, and treatment depth. Consensus guidelines should be updated using these data rather than relying on a universal waiting period.
BACKGROUND: Isotretinoin is a highly effective treatment for severe nodulocystic acne. Concerns regarding impaired wound healing and an increased risk of hypertrophic or keloid scarring have historically led to recommendations that cutaneous procedures be delayed for at least 6 months after isotretinoin therapy. Recent evidence has challenged the necessity of this practice. OBJECTIVE: To review the current literature evaluating the effects of isotretinoin on skin and wound healing in patients undergoing dermatologic, cosmetic, and surgical procedures. METHODS: A comprehensive review of published studies examining wound healing outcomes, scarring, and procedural complications in patients receiving concurrent or recent isotretinoin therapy was performed. Evidence was evaluated across multiple procedure categories, including dermabrasion, laser treatments, chemical peels, microneedling, cutaneous surgery, ophthalmic surgery, and other surgical interventions. RESULTS: Most contemporary studies reported normal wound healing and a low incidence of adverse scarring in patients undergoing procedures during or shortly after isotretinoin treatment. Evidence supporting a mandatory 6-month discontinuation period was limited and was largely based on older case reports and small case series.
