En coup de sabre variant of linear morphea (LM) is a rare sclerotic skin disorder characterized by disfiguring linear depression of the frontal or frontoparietal forehead. Current attempts for cosmetic correction of atrophic lesions must be preceded by an evaluation of disease activity of LM, either by a sufficient clinical assessment or histologic evidence. Corrective procedures including corrective surgery, autologous fat grafting, hyaluronic acid filler injections were performed with varying degrees of success; still, there is a need for treatment options with non-invasive and long-term maintenance effects. Herein we report the use of micronized acellular dermal matrix filler as a novel and successful treatment for the atrophic defect of LM in a 24-year-old female. Molecular characteristics of the micronized acellular dermal matrix filler give enhanced durability and prolonged volume consistency, which results in a long-term extracellular matrix remodeling effect.

Extramammary Paget’s disease (EMPD) is a rare malignant neoplasm of the apocrine sweat gland-bearing skin in the genital, perianal, or axillary region. EMPD may simultaneously occur in the genital and both sides of the axillae, termed as “triple EMPD,” which was first reported by Kawatsu and Miki in 1971. Since its first description, 28 Japanese and only 4 Caucasian cases of triple EMPD have been reported. Here, we present the first Korean case of triple EMPD in the groin and bilateral axillae in a 46-year-old female patient whose axillary lesions appeared consistent with seborrheic keratosis. This case emphasizes the need to consider EMPD in differential diagnosis when evaluating acanthotic axillary lesions since it can mimic benign lesions.

Purpose: Fractional microneedle radiofrequency (FMR) systems are used to treat inflammatory acne and scarring. Nonetheless, few controlled studies have combined this treatment with the traditional ablative fractional laser (AFL). We aimed to assess the safety and efficacy of the combination of FMR and AFL versus AFL alone in treating acne and acne scars. Materials and Methods: In this 20-week, randomized, split-face study, 23 Korean patients with facial acne and acne scars underwent FMR and AFL treatments. One half of each patient’s face was randomly assigned to receive FMR+AFL, whereas the other half received AFL alone. Treatments were administered in three consecutive sessions at 4-week intervals. This study investigated the severity of inflammatory acne, acne scars, individual lesion counts, depressed scar volumes, as well as patient and physician satisfaction. In addition, five patients underwent skin biopsy, and sebum output was measured. Results: The FMR+AFL treatment demonstrated superior efficacy compared to AFL alone in terms of inflammatory acne and acne scar grading, lesion counts, and subjective satisfaction. The side effects were minimal and well-tolerated in both groups. Immunohistochemical findings from skin biopsy samples revealed that the application of FMR+AFL could induce an inhibitory effect on sebum secretion at the molecular level. Conclusion FMR combined with AFL is a well-tolerated and effective treatment modality for inflammatory acne and acne scarring.

PURPOSE: This study aimed to investigate the outcomes of modular neck-utilization in primary total hip arthroplasty (THA). MATERIALS AND METHODS: Thirty patients (34 hips) who had modular stem THA between April 2011 and January 2013 were evaluated. There were 19 men and 11 women with a mean age of 61.2 years at the time of surgery. There were 20 cases of osteonecrosis of femoral head, 7 cases of osteoarthritis, 6 cases of femur neck fracture, and 1 case of rheumatoid arthritis. No patients presented with anatomical deformity of hip. Patients were operated on using a modified Watson-Jones anterolateral approach. All patients underwent clinical and radiological follow-up at 6 weeks, 3, 6, and 12 months, and every year postoperatively. The mean duration of follow-up was 48.2 months (range, 39 to 59 months). RESULTS: The average Harris hip score improved from 63.7 to 88.1 at the final follow-up. Radiographically, mean acetabular cup inclination was 45.3°(range, 36°-61°) and anteversion was 21.7°(range, 11°-29°). All were neutral-positioned stems except 5 which were varus-positioned stems. In only 3 cases (8.8%), varus or valgus necks were required. A case of linear femoral fracture occurred intraoperatively and 1 case of dislocation occurred at postoperative 2 weeks. No complications at modular junction were occurred. CONCLUSION: Our study shows that the use of modular necks had favorable clinical and radiographic results. This suggests that the use of modular neck in primary THA without anatomical deformity is safe at a follow-up of 39 months.

Background: Postoperative scars following cleft lip surgery are frequently accompanied by cosmetic and functional problems; therefore, patients with cleft lip scars usually undergo various long-term scar treatment courses. Currently, only a limited number of fractional laser treatment cases of cleft lip scars have been reported. Objective: This study aimed to evaluate the safety and efficacy of the combination laser treatment for hypertrophic scar management following cleft lip surgery. Methods: This single-center retrospective study included 27 patients who underwent cleft lip surgery before 12 months of age. The control group comprising 13 patients received only a silicone gel or sheet for the scars, while the treatment group comprising 14 patients underwent laser treatment with a 1,550 nm non-ablative fractional erbium-glass laser, followed by a 10,600 nm ablative fractional carbon dioxide laser. Intralesional triamcinolone injection (5∼10 mg/mL) was administered immediately after laser treatment. Scar improvement was assessed at 1, 3, and 6 months after surgery using the Vancouver Scar Scale. Results: The mean total Vancouver scar scale showed a statistically significant improvement in the treatment group compared to that in the control group. In the sub-analysis of pigmentation, the vascularity, pliability, and height significantly improved in the treatment group. No differences in the patients’ baseline characteristics between the two groups were noted. No significant adverse effects were observed during the follow-up. Conclusion Combination laser therapy using fractional lasers and intralesional triamcinolone injection is safe and effective for managing cleft lip surgery scars in infantile patients.

Objective: The cervical spine presents challenges in treating metastatic cervical spinal tumors (MCSTs). Although the efficacy of cervical pedicle screw placement (CPS) has been well established, its use in combination with 5.5-mm rods for MCST has not been reported. This study aimed to evaluate the efficacy of CPS combined with 5.5-mm rods in treating MCST and compare it with that of CPS combined with traditional 3.5-mm rods. Methods: This retrospective study analyzed 58 patients with MCST who underwent posterior cervical spinal fusion surgery by a single surgeon between March 2012 and December 2022. Data included demographics, surgical details, imaging results, numerical rating scale score for neck pain, Eastern Cooperative Oncology Group performance status, and Spine Oncology Study Group Outcomes Questionnaire responses. Results: Preoperative Spinal Instability Neoplastic Scores were significantly higher in the 5.5-mm rod group. Greater kyphotic changes in the index vertebra were observed in the 3.5-mm rod group. Neck pain reduction was significantly better in the 5.5-mm rod group. Conclusion CPS with 5.5-mm rods provides superior biomechanical stability and effectively resists forward bending momentum in posterior MCST fusion surgery. These findings support the use of 5.5-mm rods to enhance surgical outcomes.
