Background:
We aimed to clarify the safety and efficacy of simultaneous skin exposure to blue, red, and infrared light. The purpose of this study was to confirm the mechanism by which multiple wavelengths increase hair development both in vivo and in vitro.
Methods:
Cultured human dermal papilla cells (hDPCs) were exposed to a 470/655/850 nm light-emitting diode (LED) array with a fixed energy density of 3.0 mW/cm 2 . We analyzed alkaline phosphatase (ALP) staining and activity. The relative expressions of ALP, VEGF, Shh, and OPN3 were examined using reverse transcriptasepolymerase chain reaction arrays 48 hours post-exposure and the protein levels related to extracellular signalregulated kinase (ERK)/protein kinase B (AKT)/glycogen synthase kinase 3 (GSK3)β signaling were assessed by western blotting. Next, we used H&E staining, hair growth scoring, skin thickness measurement, and the immunohistochemical analysis of the dorsal skin of C57BL/6 mice to investigate the effects of the mono- or combined-photobiomodulation (PBM) groups.
Results:
According to our findings, simultaneous irradiation with multi-wavelength LEDs at 470/655/850 nm increased the proliferation of hDPCs. Also, compared to the control group, the red wavelength and combined PBM groups had significantly improved skin thickness measurements. Overall, we concluded that the combined PBM therapy successfully induced the early onset of anagen and stimulated hair growth.
Conclusion
These results suggest that PBM therapy regulates hair growth by activating the ERK/AKT/GSK3βsignaling pathway. Thus, multiple-wavelength radiation from devices combining radiation emitted by lowpower lasers and LEDs could be a new approach for promoting PBM-induced beneficial effects.

Copolyamide fillers, such as Aquafilling, have been used off-label for breast augmentation in many countries, including Korea. However, safety concerns have arisen due to reported complications, including induration, masses, mastalgia, firmness, asymmetry, migration, infection, and dimpling. We report the case of a 33-year-old woman who presented with distant migration of copolyamide breast filler to the left lower abdomen and inguinal area following mammography for breast cancer screening. This case highlights the potential risks associated with the migration of copolyamide breast fillers, particularly in the context of cancer screening procedures, and emphasizes the importance of awareness and vigilance among clinicians and patients.

Purpose:
There are few reports on outcomes following surgical repair of recurrent rectal prolapse. The purpose of this study was to examine surgical outcomes for recurrent rectal prolapse.
Methods:
We conducted a multicenter retrospective study of patients who underwent surgery for recurrent rectal prolapse. This study used data collected by the Korean Anorectal Physiology and Pelvic Floor Disorder Study Group.
Results:
A total of 166 patients who underwent surgery for recurrent rectal prolapse were registered retrospectively between 2011 and 2016 in 8 referral hospitals. Among them, 153 patients were finally enrolled, excluding 13 patients who were not followed up postoperatively. Median follow-up duration was 40 months (range, 0.2–129.3 months). Methods of surgical repair for recurrent rectal prolapse included perineal approach (n = 96) and abdominal approach (n = 57). Postoperative complications occurred in 16 patients (10.5%). There was no significant difference in complication rate between perineal and abdominal approach groups. While patients who underwent the perineal approach were older and more fragile, patients who underwent the abdominal approach had longer operation time and admission days (P < 0.05). Overall, 29 patients (19.0%) showed re-recurrence after surgery. Among variables, none affected the re-recurrence.
Conclusion
For the recurrent rectal prolapse, the perineal approach is used for the old and fragile patients. The postoperative complications and re-recurrence rate between perineal and abdominal approach were not different significantly. No factor including surgical method affected re-recurrence for recurrent rectal prolapse.

BACKGROUND: Because many cosmetic surgery clinics are not adequately equipped to handle emergent conditions, patients often come to a university hospital when problems occur during or after cosmetic surgery. However, few in-depth studies have been conducted of this issue. Therefore, we investigated emergency department visits due to complications associated with cosmetic surgery. METHODS: A retrospective chart review was conducted of 38 patients who visited the emergency department of the authors' institution due to complications associated with cosmetic surgery from July 2014 to June 2017. RESULTS: There were more women than men (30 women vs. 8 men). Their mean age was 32.4 years (range, 19–57 years). Upon presentation to the emergency department, patients' vital signs and mental status were usually normal (27 normal vs. 11 abnormal). The types of surgery included blepharoplasty, rhinoplasty, malar/orthognathic surgery, mammaplasty, liposuction, fat grafting, and filler and botulinum toxin injections. Most patients required hospitalization (26 admitted vs. 12 discharged). Eight of the hospitalized patients required intensive care unit care, of whom two died and three experienced brain death or had permanent neurologic sequelae. CONCLUSIONS: The complications were usually minor problems, despite the need for hospitalization, but some complications were life-threatening. We recommend close monitoring and maintaining an adequate injection capacity for intravenous sedative anesthesia. When any symptom or sign of a complication occurs, it is best to transfer the patient to a university hospital as soon as possible. Taking a careful medical history is always needed, even for minor procedures.

A-50-year-old male patient presented with complaint of tenderness on the left malar area after traffic accident. Our first impression on him was zygomatic fracture, we did radiologic work-up and physical examination on him. But, on the computed tomography scan, there was no fracture or discontinuity on his facial bone. The computed tomography scan was revealed a 4-cm long foreign body in left maxillary sinus with a large amount of fluid collection. After thorough history taking from him, we reveal the patient had a history of trauma 30 years back on the left zygomatic area with a chopstick. The foreign body was removed via transoral approach with the endoscopic assist. There was no complication after operation.

BACKGROUND: The latissimus dorsi (LD) flap is widely used in breast cancer reconstruction, but donor-site morbidity is one of the major limitations of this surgery. Donor-site seroma is the most common complication. To prevent seroma formation, we consider the use of a fibrin sealant (FS) because of its hemostatic and sealing effects. In this study, we investigate the effect of a FS on seroma prevention and as a hemostatic agent at the LD donor site. METHODS: A retrospective study was conducted from 2011 to 2015. Herein, we analyzed the preoperative status, changes in the hemoglobin (Hb) level according to the postoperative day, postoperative drain amount, and the drain removal time. RESULTS: The decline in the Hb level was not statistically significantly less in the FS group than in the control group. Further, the difference in the drain amount between the 2 groups was not statistically significant either. The seroma rate and the drain removal time between the 2 groups also did not show any statistically significant difference. CONCLUSIONS: The FS does not have hemostatic effect and the drain amount reduction in the early phase of recovery and does not prevent seroma. Therefore, an empirical use of the FS alone is no longer recommended to prevent seroma. In contrast, the quilting suture has been reported to be effective in seroma prevention. Therefore, it is necessary to study the effects of a combination of quilting sutures and the FS on seroma and the other risk factors of this surgical complication.

PURPOSE: The goal of oncoplastic breast surgery is to restore the appearance of the breast and improve patient satisfaction. Thus, the assessment of cosmetic results and patient-reported outcomes (PROs) using appropriately constructed and validated instruments is essential. The aim of the present study was to assess the long-term objective cosmetic results and corresponding PROs after oncoplastic breast surgery. METHODS: Cosmetic results were assessed by the patients, a medical panel, and a computer program (BCCT.core). PROs were assessed using BREAST-Q, a questionnaire that measures the perception of patients having breast surgery. The cosmetic results and PROs were analyzed in patients who underwent quadrantectomy and partial breast reconstruction utilizing the latissimus dorsi flap. RESULTS: The mean duration of the follow-up period was 91.6 months (range, 33.3-171.0 months), and mean age of the patients was 51 years old (range, 33-72 years). The mean tumor size was 2.1 cm (range, 0.9-5.5 cm). There was fair agreement between the medical panel and BCCT.core score (K = 0.32, P < 0.001), and a statistically significant correlation between the BCCT.core score and medical panel cosmetic results was identified (r = 0.606, P < 0.001). A better BCCT.core result was related to a higher PRO of each BREAST-Q domain-satisfaction with breasts (R2 = 0.070, P = 0.039), satisfaction with outcome (R2 = 0.087, P = 0.021), psychosocial well-being (R2 = 0.085, P = 0.023), sexual well-being (R2 = 0.082, P = 0.029), and satisfaction with information (R2 = 0.064, P = 0.049). CONCLUSION: Our long-term results of oncoplastic surgery achieved a high level of patient satisfaction with good cosmetic results. The medical panel and BCCT.core results correlated well with the PROs of the patients using valid, reliable, and procedure-specific measures.

Hepatitis C virus (HCV) infection is present in a high proportion of patients with kidney transplantation. Compared with uninfected kidney transplant recipients, HCV infected kidney recipient have higher prevalence of liver disease and worse allograft survival after transplantation. Interferon monotherapy before transplantation is standard therapy for HCV-infected kidney transplant candidates. If HCV infection is discovered after transplantation, interferon monotherapy is considered due to the limited critical situation. However, in this patient, who was a kidney recipient, HCV infection was treated after kidney transplantation with peginterferon-α and rivabirin. As a result, the patient achieved sustained virologic response.

Archives of Plastic Surgery 2016;43(6):551-558
BACKGROUND: Fascial free flaps have been widely used for reconstruction of the hand because they are thin. However, studies reporting objective data regarding the advantages of this approach are lacking. Thus, we report our experience with such flaps. METHODS: Forty-five cases of fascial free flaps between November 2006 and March 2014 were reviewed. Nine cases involving reconstructed dorsal or lateral defects were included. Four anterolateral thigh fascial free flaps and 5 lateral arm fascial free flaps were examined. Maximal flap contour was assessed by measuring reconstructed tissue thickness at the central area from the surface of the skin to below the bone in a vertical manner using ultrasonography and X-ray data. Contralateral regions were examined in the same manner and a comparative analysis was performed. A questionnaire survey regarding aesthetic satisfaction was also administered. RESULTS: All reconstructed parts had a thicker contour than the contralateral side. The average relative percentage of reconstructed tissue thickness was found to be 152% using ultrasonography and 143% using X-ray imaging. According to the aesthetic satisfaction survey, the average rate of satisfaction for patients was 62%, and satisfaction with the flap contour was 72%. CONCLUSIONS: Using a fascial free flap, the reconstructed tissue was approximately 1.5× as thick as the contour of the normal side, which led to positive responses regarding aesthetic satisfaction.
