1. Low-Dose Oral Minoxidil Improves Hairline and Eyebrow Coverage in Frontal Fibrosing Alopecia: A Prospective Study.
In a 6-month prospective single-arm study of 11 women with biopsy-proven FFA, low-dose oral minoxidil (1 mg/day) improved anterior hairline coverage in 9/10 completers and eyebrows in 4/8 assessed. Mild hypertrichosis was the most common adverse effect (5 cases), and one patient discontinued due to a transient ischemic attack; blinded expert ratings supported improvement.
Impact: Provides prospective, blinded-assessed evidence that LDOM can enhance cosmetic coverage in scarring alopecia, addressing an unmet need beyond inflammation control.
Clinical Implications: Consider off-label LDOM (e.g., 1 mg/day) as an adjunct to anti-inflammatory regimens in stable FFA to enhance coverage, with counseling about hypertrichosis and rare cardiovascular events and periodic monitoring.
Key Findings
- Prospective 6-month single-arm treatment with oral minoxidil 1 mg/day in 11 biopsy-proven FFA patients.
- Among 10 completers, 9 improved anterior hairline coverage; eyebrows improved in 4 of 8 evaluated.
- Mild hypertrichosis occurred in 5 cases; one discontinuation due to transient ischemic attack.
- Blinded evaluation of standardized photographs and trichoscopy showed improvement in at least one area in all completers.
Methodological Strengths
- Prospective design with blinded dual-expert assessment using a predefined 5-point scale
- Standardized imaging (photography and trichoscopy) and biopsy confirmation; safety monitored clinically and via labs
Limitations
- Small sample size (n=11) and single-arm design without a control group
- Short follow-up (6 months) limits assessment of durability and safety
- One serious adverse cerebrovascular event leading to discontinuation
Future Directions: Randomized controlled trials to quantify efficacy versus standard care, dose–response and combination strategies, and longer-term cardiovascular safety profiling.
INTRODUCTION: Frontal fibrosing alopecia (FFA) is a primary lymphocytic scarring alopecia that commonly presents with frontotemporal hairline recession and eyebrow loss. While most treatments aim to control inflammation and stop disease progression, low-dose oral minoxidil (LDOM) has been proposed to enhance coverage of remaining hairs and improve cosmetic outcomes. METHODS: In this prospective study, adult women with biopsy-proven FFA received oral minoxidil 1 mg/day for 6 months. Standardized photographs and trichoscopy images were obtained at baseline and after treatment and blindly evaluated by two independent experts using a 5-point scale (-2 to +2). Safety was monitored through clinical and laboratory assessments. All patients gave consent for use of their photographs. RESULTS: A total of 11 women were included (mean age 58.2 years); one discontinued treatment due to a transient ischemic attack. Among 10 completers, all showed improvement in at least one area, with increased anterior hairline coverage in nine and eyebrow improvement in four of eight evaluated patients. Mild hypertrichosis occurred in five cases. CONCLUSIONS: LDOM improved anterior hairline and eyebrow coverage in women with FFA and was generally well-tolerated. Protocol Number: HSPM58444422.0.0000.5442.
2. Retraction: Cosmetic talc powder.
The Lancet editors issued a retraction for the article titled 'Cosmetic talc powder,' indicating the work is withdrawn from the scientific record. Specific reasons are not provided in the supplied text, underscoring the need to reassess any downstream citations or guidance relying on that article.
Impact: A high-visibility retraction affects the evidence base around cosmetic talc safety and emphasizes research integrity and cautious risk communication.
Clinical Implications: Clinicians and policymakers should cease citing the retracted article, review any recommendations informed by it, and monitor for replacement evidence from rigorous studies.
Key Findings
- Formal retraction of the article 'Cosmetic talc powder' by The Lancet editors.
- The retraction signals that the paper’s findings are no longer part of the scientific record and should not be relied upon.
- Specific reasons for the retraction are not included in the provided text.
Methodological Strengths
- Transparent editorial corrective action in a leading general medical journal
- Permanent bibliographic flagging improves dissemination of the correction
Limitations
- No new empirical data are provided
- Specific rationale for retraction is not detailed in the supplied text
Future Directions: Clarify the grounds for retraction and re-evaluate cosmetic talc safety with robust, transparent methodologies.
3. Posterior auricular seborrheic keratosis treated with bilobed flap reconstruction: a case report.
A rare posterior auricular seborrheic keratosis in a 68-year-old woman was excised and reconstructed using a bilobed flap, achieving tension-free closure while preserving the retroauricular sulcus. Histology confirmed seborrheic keratosis without atypia, and there were no complications or recurrence at 3 months with satisfactory cosmetic and functional outcomes.
Impact: Documents a rare auricular presentation and provides a reproducible seven-step bilobed flap technique yielding strong cosmetic and functional results.
Clinical Implications: For large posterior auricular defects after benign tumor excision, a bilobed flap using mastoid and lateral neck skin can offer tension-free closure while preserving auricular contours, provided histopathology excludes malignancy.
Key Findings
- Posterior auricular seborrheic keratosis is rare; this case involved a 3×2 cm mass enlarging over 5 years in a 68-year-old woman.
- Preoperative biopsy and postoperative histology confirmed seborrheic keratosis with acanthosis, papillomatosis, hyperkeratosis, and horn cysts without atypia.
- Bilobed flap reconstruction using mastoid and lateral neck skin achieved tension-free closure, preserved the retroauricular sulcus, and had no complications or recurrence at 3 months.
Methodological Strengths
- Definitive histopathologic diagnosis confirming benign etiology
- Detailed seven-step operative technique enabling reproducibility and aesthetic preservation
Limitations
- Single-patient case limits generalizability
- Short follow-up (3 months) precludes long-term assessment
- No comparative evaluation against alternative reconstruction methods
Future Directions: Aggregate additional cases with longer follow-up and comparative studies of flap options to optimize auricular reconstruction algorithms.
BACKGROUND: Seborrheic keratosis is a common benign epidermal neoplasm, typically arising on the trunk, face, and extremities. Auricular involvement is rare, and posterior auricular presentation is particularly uncommon, with few cases reported. CASE PRESENTATION: We describe a 68-year-old Iranian woman presenting with a 3 cm × 2 cm posterior auricular mass that had slowly enlarged over 5 years. The lesion was firm, nontender, and fixed to underlying tissue, raising concern for malignancy. A preoperative biopsy was performed, and histopathology confirmed seborrheic keratosis. Given the lesion's size and atypical location, complete surgical excision was undertaken. Reconstruction of the resulting defect was achieved using a bilobed flap, executed in seven operative steps, utilizing mastoid and lateral neck skin to provide tension-free closure while preserving the retroauricular sulcus. Microscopic evaluation revealed acanthosis, papillomatosis, hyperkeratosis, and horn cysts without evidence of atypia or malignant transformation. The postoperative course was uneventful, with no complications or recurrence observed at 3-month follow-up. Both aesthetic and functional outcomes were satisfactory. CONCLUSION: This case highlights the rarity of posterior auricular seborrheic keratosis and underscores the importance of histopathological confirmation in lesions with indeterminate clinical features. The bilobed flap provided reliable coverage for a relatively large auricular defect, achieving favorable cosmetic and functional results. Documentation of such uncommon cases contributes to improved diagnostic accuracy and supports evidence-based surgical management of auricular tumors.
