Purpose: Metacarpal fractures are common hand injury that may require operative intervention to ensure adequate reduction and stabilization. Traditionally, titanium miniplate was used for rigid fixation of bone fractures. However, the use of permanent plate lends itself to multiple complications such as infection, exposure of the hardware, tendon adhesions, tendon rupture, prolonged pain, bony atrophy and osteoporosis (stress shielding), metal sensitization, and palpation under the skin. This study evaluated the usefulness and stability of biodegradable plates and screws for treatment of metacarpal bone fractures. Methods: There was 17 patients who had surgery for metacarpal bone fracture from April 2007 to June 2010. All patients had open reduction and internal fixation. We used absorbable plates and screws (Inion CPS$^{(R)}$) for internal fixation. Postoperative results were assessed with x-ray. Stability of plates and screws, healing process and its complications were observed by clinical and radiographic assessment. Results: All patients were successfully reduced of bone fracture, and fixations with absorbable plates and screws were stable. The mean follow up period was 7.1 months. 2 patients complained postoperative pain, but they were relieved with analgesics. All patients experienced transient stiffness, but they were relieved with active assistive range of motion after removal of splint. No patients suffered complications which could be occurred by using metallic plate. Conclusion: There was no critical complications such as re-fracture or nonunion among patients. No patients suffered side effects related with metallic implants. Biodegradable implants can offer clinically stable and attractive alternative to metallic implants to stabilize metacarpal bone fractures in the hand.

This is a report on a total of 11 cases of esophageal perforation in the department of thoracic surgery, Chonnam University Hospital during the period of 8 years from 1962 to 1969. They occurred by the following agents, that is,lye solution[7 cases], fish bone[2 cases]. compress air [one case], strong acid [one case]. The perforated portions of esophagus were cervical esophagus in 2 cases, upper third of esophagus in 5 cases, middle third of esophagus in 3 cases and lower third of esophagus [abdominal esophagus] in one case. 4 cases out of cases of esophageal perforation after ingestion of Lye solution were due to Bougination to improve esophageal stenosis: 2 cases occurred 2 months after ingestion of Lye solution and the remaining 2 cases, 2 to 3 weeks after Lye solution ingestion. Therefore, It is realized that Bougination for esephageal stricture by Lye solution is particularly dangerous. The complication after esophageal perforation were mediastinitis,[10 cases], right pyothorax with mediastinitis [8 cases], peritonitis [4 cases], esophago-bronchial fistula[one case]. Owing to the various complications above mentioned, surgical approach to esophageal perforation is accordingly complicated and a combination of more than two of the following different procedures were properly used case by case, that is. gastrostomy or jejunostomy for feeding and esophageal rest,thoracotomy and chest drainage, lung decortication for pyothorax, primary closure of compress air perforation and esophago-bronchial fistula, mediastinostomy, retrosternal esophagoplasty using right colon to Lye stricture etc. 5 cases[45. 5%] of 11 cases were expired and the rest of 6 cases[54.5%]were survived with complete accomplishment of surgical procedures and satisfactory healing in 4 cases and interruption of follow up in 2 cases because of poor economical condition of the patients.

In this paper, we analyzed the optical properties of the LED module for dental care, which has the effect of promoting cell regeneration and scar treatment. The LED module is a U-shaped module suitable for the shape of teeth. It is manufactured with an LED module (632 nm) and an LED module (632 nm + 870 nm), analyzes the results of optical properties, sets the irradiation distance, irradiation time, and is effective in healing skin wounds. Evaluation was conducted. It was tested in 6 test groups according to the light irradiation conditions, and light was irradiated to the scar site every other day for 7 days, 1 day and 3 days. As a result, it was confirmed that the effect of scar treatment was the highest when the combined wavelength of 632 nm + 870 nm was irradiated in pulse mode than when the single wavelength was irradiated and the composite wavelength was continuously irradiated. In group C group irradiated with PW Mode: pulse mode (period 36 ms, pulse width 35 ms) using a composite wavelength with LED module (632 nm + 870 nm) than group A without light irradiation, the length of scar reduction was 19 %, the area of the scar was further reduced by 10%, and it was confirmed that it is effective in treating scars in the wound area.

Purpose: There have been few case reports regarding treatment plans for long-term, neglected scalp defects and calvarial defects with subdural abscess. The purpose of this case report is to present our experience with a free latissimus dorsi musculocutaneous flap for scalp and calvarial defects and to discuss flap options in comparison with a literature review. Methods: A 60-year-old man who fell down from a four-story-height that resulted in a craniotomy in 1979; he visited our outpatient clinic for a chronic, purulent scalp and calvarial defects with unidentified artificial bone. The artificial bone was removed by a neurosurgeon and reconstructed with a free latissimus dorsi musculocutaneous flap. The deep temporal artery was used as a recipient artery. The postoperative flap status was excellent until the 6th day post-operation when the patient experienced a seizure, and an arterial insufficiency occurred at the flap probably due to an arterial spasm. Emergency exploration with arterial re-anastomosis was performed and the flap status was stabilized. Results: Complete wound healing was achieved after 3 weeks without infectious and systemic postoperative complications. During the 6 month follow-up period, there were no complications. Conclusion: We suggest the latissimus dorsi myocutaneous free flap as a good treatment option for a chronic, purulent, complicated scalp with calvarial defect, as a well as treatment for an acute traumatic defect.

The aim of this study was to elucidate the effects of concentrated growth factors (CGFs) on human gingival fibroblasts in vitro. Blood was collected from three male volunteers (average age 27 years). CGFs were prepared using standard protocols. The CGF exudates were collected at the following culture time points: 1, 7, 14, and 21 days. The levels of platelet-derived growth factor BB (PDGF-BB) and transforming growth factor ${\beta}1$ (TGF-${\beta}1$) in CGFs were quantified. The CGF exudates were then used to culture human gingival fibroblasts. The biologic characteristics of these fibroblasts were analyzed in vitro for 21 days. Platelet-rich plasma released the highest amounts of TGF-${\beta}1$ and PDGF-BB on the first day. The level of TGF-${\beta}1$ had decreased slightly by day 7, although the difference compared to levels at day 1 was not statistically significant. However, by days 14 and 21, levels of TGF-${\beta}1$ had dropped significantly compared to day 1 levels. The levels of PDGF-BB at days 7, 14, and 21 did not differ significantly from that measured on day 1. CGFs maintained the release of autologous growth factors for a reasonable period of time (7 days for TGF-${\beta}1$ and 21 days for PDGF-BB). Gingival fibroblasts treated with CGF exudates collected at day 14 reached peak viability and synthesized type I collagen. Furthermore, the CGF exudates exerted positive effects on the proliferation and differentiation of these cells at days 1, 7, 14, and 21. The findings of this study suggest that treatment with CGFs represents a promising method of enhancing mucosal healing following surgical procedures.

The $S{\bar{u}}tra$ of Great Dhāraṇī of the Uṣṇīṣa-cittā is one of the most widely published scriptures of Esoteric Buddhism during the Goryeo and Joseon dynasty. The sutra is often referred to as a Buddhist medical scripture whose recitation is believed to allay diseases such as difficult birth, chest pain, and infectious and incurable diseases. It utilizes two major methods for healing: reciting and copying the sutra or copying the dharani and talisman which appear at the end of the text with fine cinnabar and ingesting them with aromatic water. In order to understand the medical and historical value of this sutra, this study examines the historical background of its establishment in early China and its migration to Korea in the Goryeo period. This study also investigates the identity and value of the scripture in Buddhist medical history. The oldest known printed texts of the sutra in Korea are dated to the late 11th century. Because of the material benefits of the text, the tradition of printing and distributing the sutra was very popular between the 13th and 19th centuries. Therefore, examples of the sutra having been used for medicinal purposes during rites are found in historical records. Finally, the study tries to identify the relationship between the treatment methods of the Sutra and those of Korean traditional medicine focusing on several Korean traditional medical texts such as the Hyangyak-Jibseongbang (Compilation of Native Korean Prescriptions), the Donguibogam, and the Euibang-Hapbu.

Objectives The purpose of this study was to analyze the clinical characteristics of patients with hyperhidrosis who visited a Korean medicine hospital, and provide information on treated hyperhidrosis, based on Sasang Constitutional medicine. Methods A retrospective review was made of the electronic medical record (EMR) charts for 157 Korean patients with hyperhidrosis (90 male, 67 female), who first visited hospital from January 1, 2013 to December 31, 2017. The following information was collected: sex, age, height, weight, body mass index (BMI) and clinical data (diagnosis, area of onset, duration of illness, aggravating factors, medication, healing process, et al). Results There were many patients with hyperhidrosis, in the other of So-Yang type (57.3%), Tae-Eum type (35.0%) and So-Eum type (7.6%). The proportion of male was higher than female. The most common area of hyperhidrosis was hands and feet (44.0%), followed by generalized whole body (27.4%) and head and face (25.5%). The cure rate of hyperhidrosis was 32.2%, and effectiveness rate of that was 72.7%. In individual patients, the better the usual health condition expressed by original symptoms, the higher the possibility of treatment success, with shortened duration of treatment and reduced total drug dose. The most frequent treatment modality in patients was that consistently improved, and this duration of treatment was statistically significantly shorter than that experienced worsening of excessive sweating during treatment period (p<0.001). Conclusions This study provides some original information on the Korean patients with hyperhidrosis, and suggests the suitability of Sasang Constitutional medicine as treatment methods for hyperhidrosis.

Objectives: Direct pulp capping is a treatment for mechanically exposed pulp in which a biocompatible capping material is used to preserve pulpal vitality. Biocompatibility tests in animal studies have used a variety of experimental protocols, particularly with regard to the exposure site. In this study, pulp exposure on the occlusal and mesial surfaces of molar teeth was investigated in a rat model. Materials and Methods: A total of 58 maxillary first molars of Wistar rats were used. Forty molars were mechanically exposed and randomly assigned according to 3 factors: 1) the exposure site (occlusal or mesial), 2) the pulp-capping material (ProRoot White MTA or Bio-MA), and 3) 2 follow-up periods (1 day or 7 days) (n = 5 each). The pulp of 6 intact molars served as negative controls. The pulp of 12 molars was exposed without a capping material (n = 3 per exposure site for each period) and served as positive controls. Inflammatory cell infiltration and reparative dentin formation were histologically evaluated at 1 and 7 days using grading scores. Results: At 1 day, localized mild inflammation was detected in most teeth in all experimental groups. At 7 days, continuous/discontinuous calcified bridges were formed at exposure sites with no or few inflammatory cells. No significant differences in pulpal response according to the exposure site or calcium-silicate cement were observed. Conclusions: The location of the exposure site had no effect on rat pulpal healing. However, mesial exposures could be performed easily, with more consistent results. The pulpal responses were not significantly different between the 2 capping materials.

Background Mastectomy in male transgender patients is an important (and often the first) step toward physical manhood. At our department, mastectomies in transgender patients have been performed for several decades. Methods Recorded data were collected and analyzed for all male transgender patients undergoing mastectomy over a period of 24 years at our department. Results In total, 268 gender-reassigning mastectomies were performed. Several different mastectomy techniques (areolar incision, n=172; sub-mammary incision, n=96) were used according to patients' habitus and breast features. Corresponding to algorithms presented in the current literature, certain breast qualities were matched with a particular mastectomy technique. Overall, small breasts with marginal ptosis and good skin elasticity allowed small areolar incisions as a method of access for glandular removal. In contrast, large breasts and those with heavy ptosis or poor skin elasticity often required larger incisions for breast amputation. The secondary correction rate (38%) was high for gender reassignment mastectomy, as is also reflected by data in the current literature. Secondary correction frequently involved revision of chest wall recontouring, suggesting inadequate removal of the mammary tissue, as well as scar revision, which may reflect intense traction during wound healing (36%). Secondary corrections were performed more often after using small areolar incision techniques (48%) than after using large sub-mammary incisions (21%). Conclusions Choosing the suitable mastectomy technique for each patient requires careful individual evaluation of breast features such as size, degree of ptosis, and skin elasticity in order to maximize patient satisfaction and minimize secondary revisions.
