Purpose: The emergency of multi-drug resistant stains of bacteria represents a challenge in the field of plastic surgery. Especially, MRSA(methycillin-resistant Staphylococcus aureus) and Pseudomonas aeruginosa have strong pathogenicity as well as multi-drug resistance so that they have become a lot more problematic strains. This study has been planned to reduce the bacterial burden by applying $Acticoat^{(R)}$(Smith & Nephew Healthcare, Hull, England)dressing into the chronic wounds infected by multi-drug resistant strains and to facilitate their healing. Methods: Nanocrystalline silver dressings($Acticoat^{(R)}$) were applied to chronic wound infected by MRSA or Pseudomonas aeruginosa. Multi-drug resistant bacteria were smeared over a slide glass using sterilized cotton swabs and gram stains were performed directly before and after applying $Acticoat^{(R)}$ dressings at 1, 24, 48 and 72 hours. The gram-stained slides were observed using an optical microscope magnified 1000 times(${\times}1000$). The bacterial counts of the control group(0 hour) were compared to those of the experimental groups(1, 24, 48, and 72 hour). Paired T-test was used to assess a statistical significance. MRSA was cultured in two BAPs(blood agar plate) and two MacConkey plates with streak plate method. None were interventions on one culture plate, while on the other culture plate, $Acticoat^{(R)}$ was placed in a square shape and cultured for 72 hours at $37^{\circ}C$, then plates were examined. Pseudomonas aeruginosa was cultured in the same manner as MRSA. Results: There are the large amount of declination of bacterial counts with statistical significance after $Acticoat^{(R)}$ dressing. The bacteria grew in culture plate without specific intervention, but no bacteria grew in culture plate with applying of $Acticoat^{(R)}$ dressing. Conclusion: We believe that $Acticoat^{(R)}$ dressing could be used as an effective method of treating chronic wounds which are infected by multi-drug resistant organisms.

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.
Background A car-tire friction injury on the dorsum of a child's foot often results in hypertrophic scarring of the wound margins. This study describes the clinical appearance of the injured areas and surgical complications that occurred during the follow-up period in a series of children with car-tire friction injuries who were treated with split-thickness skin grafts (STSGs). We describe the clinical features that we believe need to be highlighted when initially treating car-tire injuries in children. Methods From May 2003 to June 2016, our retrospective study included 15 patients with car-tire injuries on the dorsum of the foot who were treated with surgical excision and STSG to cover the wound. Results A total of 15 patients with car-tire injuries were treated. The average age was 6.26 years old. The average injury grade was 3.26. Two patients were treated using delayed repair, and 13 patients received STSG for initial management. Four patients experienced no complications, while 11 patients had hypertrophic scars and/or scar contracture after surgery. Conclusions A car-tire friction injury on the dorsum of a child's foot often results in hypertrophic scar formation or scar contracture even if proper management is undertaken. Since the occurrence of these complications in childhood can lead to a secondary deformity, it is important to properly treat car-tire friction wounds, inform patients and caregivers about potential complications, and ensure regular follow-up evaluations over a 12-month period following the initial surgery.
Various surgical procedures have been described for treating osmidrosis axillare. Elimination of the apocrine glands is prime goal. Optimal operative procedure is characterized as follows: minimal axillary scar(which has cosmetic merits), less complications such as hematoma and seroma, short and less painful recuperating period, minimal damage to the skin and low recurrence rate. Three types of incision technique in subdermal shaving method have beeb commoly used. First, single incision method has an advantage of minimal scarring but more recurrence due to incomplete removal of apocrine glands may occur. Second, double incision technique(Bipedicled flap) has advantages of complete excision, low recurrence rate and relatively minimal scarring, but it could cause frequent necrosis of skin and folding of skin flap. Skoog's method is the third method, which makes four flaps by offset cruciate incisions. It is a better technique in aspect of complete excision of apocrine glands and low recurrence rate but has disadvantages such as development of hypertrophic scar or scar contracture in the line that lies perpendicular to natural axillary skin crease. We used a modified procedure which has shorter length in vertical and transverse incision compared with the classic Skoog's method. We dissected further subcutaneous tissue through the diamond-shaped incision and utilize wide operation field that provide adequate excision of subdermal tissue and proper hemostasis. Between 1999 and 2004, we operated 160 osmidrosis axillare in 80 patients in this technique. Most patients obtained satisfactory result with very low complications. Hematoma or seroma 3.1% Infection 0.6% Partial wound disruption 10% Recurrence 1.2%. Modified Skoog's method for treating osmidrosis axillae could be a optimal technique providing wide operation field for adequate excision of apocrine glands and proper hemostasis and leaving relatively inconspicuous scar and low incidence of scar contracture.

Purpose: Surgical excision of the subcutaneous tissues, with or without skin excision in the axillary hair-bearing area, has been the treatment of choice in treating osmidrosis for several decades. However, long periods of postoperative immobilization of a shoulder joint, partial necrosis of skin flaps or the possibility of hematoma and scars have occurred frequently. So we used $XPS^{(R)}$ microresector(Shaver) in procedure which requires removal of soft tissue for comparing results between surgical excision and the laters. Methods: From January 2007 to February 2008, a total of 20 patients(8 male and 12 female) underwent $XPS^{(R)}$ microresector(Shaver) assisted aspiration for treating osmidrosis. The mean age of the subjects was 21.9, and we tried to analyze some advantages of $XPS^{(R)}$ microresector(Shaver). Results: The average operation time was 61.6 minutes. This results can show that the patients who received $XPS^{(R)}$ microresector(Shaver) assisted aspiration can accomplish better outcomes than any other procedures in terms of operation time at least. Moreover, no significant postoperative complications occurred in our studies. Subjects have been followed up from 2 months to 1 year and among these patients, no one suffered from critical complications. Conclusion: In brief, $XPS^{(R)}$ microresector(Shaver) is able to shorten the time of operation and simplify the procedures relatively and this device has more superiorities in wound healing by maintaining of vascularized dermal skin flaps. It means that $XPS^{(R)}$ microresector (Shaver) can prevent flap necrosis, axillary hair loss and minimalize scarring and bleeding. Thus, we expect that these advantages can lead to better patient's comfort and self-confidence than several previous procedures.
Purpose: Diabetic foot infection is one of the most common and severe complications of diabetes mellitus that delays healing of the wound. Deep tissue biopsy is considered to be the gold standard method for antibiotic selection in treating infected chronic diabetic ulcers. However, swab culture or superficial tissue biopsy is often performed for a microbiologic test since deep tissue biopsy has limitations in application. The purpose of this study is to find out whether microbiologic results of swab culture or superficial tissue biopsy could be used for selection of antibiotics in treating diabetic ulcers. Methods: This study involved 42 patients with diabetic foot ulcers with negative results in bone probing test. Tissue samples for microbiologic tests were collected from all the patients by using superficial cotton swab, superficial tissue, and deep tissue. The microbiologic results of deep tissue biopsy were compared with swab culture and superficial tissue biopsy statistically. Results: Microbiology of the deep tissue showed the same results with those of the swab culture and superficial tissue in 67% and 71%, respectively. Statistical analysis demonstrated that the microbiology of the swab culture and superficial tissue does not coincide with that of the deep tissue. Conclusion: These results suggest that the microbiology of the swab culture and superficial tissue is not concordant with that of the deep tissue in infected chronic diabetic ulcers. To select appropriate antibiotic regimen, the speci specimen for the microbiologic test should be obtained from deep tissue.

Background and Objectives: The reconstruction is very important in Head and neck cancer surgery to repair the defect created by resection of tumors, to enable successful wound healing, to restore function and to provide acceptable cosmesis. The radial forearm free flap has been the most useful reconstructive flap because it provides a moderate amount of thin, pliable, relatively hairless skin and comparatively simple to do with minimal morbidity. The aims of this study is to estimate the outcome of the reconstruction with radial forearm free flap with the several factors in 140 head and neck cancer cases in our hospital for last 10 years. Materials and Methods: Retrospective review of the records of 140 patients underwent resection of the head and neck tumors and reconstruction with a radial forearm free flap from 1993 to 2003. The age, sex of the patients, Primary site, the complication of donor and recipient site, flap survival rate, median time to start diet, patient subjective symtoms about swallowing and articulating and the fact of revision reconstructive surgery were analyzed. Results: In primary pathologic site, 56 cases were oral cavity cancers, 44 cases, oropharyngeal cancers and 22 cases, hypopharyngeal cancers. Flap survival rate was 93.6% (13 leases). On donor site, wound dehiscence, hematoma, sensory change and infection were noted and on recipient site, most common complication were fistula and wound dehiscence. The complication rate of recipient's site was 19.1 % and donor site, 3.5%. In 118 cases (84.3%), the patients could take all kinds of food. Swallowing difficulty were noted in 22 cases 05.7%). In 5 cases, there was articulation difficulty but most of patients except patients having total laryngectomy (18 cases) couldn't have any difficulty in articulation and speaking. Conclusion: We conclude that the radial forearm free flap is the most appropriate reconstructive material for treating the defect in head and neck reconstruction.

Purpose: Biphasic calcium phosphate (BCP), a widely used biomaterial for bone regeneration, contains synthetic hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP), the ratio of which can be adjusted to modulate the rate of degradation. The aim of this study was to evaluate the clinical and radiographic benefits of reconstructing peri-implant bone defects with a newly developed BCP consisting of 60% β-TCP and 40% HA compared to demineralized bovine bone mineral (DBBM). Methods: This prospective, multicenter, parallel, single-blind randomized controlled trial was conducted at the periodontology departments of 3 different dental hospitals. Changes in clinical (defect width and height) and radiographic (augmented horizontal bone thickness) parameters were measured between implant surgery with guided bone regeneration (GBR) and re-entry surgery. Postoperative discomfort (severity and duration of pain and swelling) and early soft-tissue wound healing (dehiscence and inflammation) were also assessed. Data were compared between the BCP (test) and DBBM (control) groups using the independent t-test and the χ2 test. Results: Of the 53 cases included, 27 were in the test group and 26 were in the control group. After a healing period of 18 weeks, the full and mean resolution of buccal dehiscence defects were 59.3% (n=16) and 71.3% in the test group and 42.3% (n=11) and 57.9% in the control group, respectively. There were no significant differences between the groups in terms of the change in mean horizontal bone augmentation (test group: -0.50±0.66 mm vs. control groups: -0.66±0.83 mm, P=0.133), postoperative discomfort, or early wound healing. No adverse or fatal complications occurred in either group. Conclusions: The GBR procedure with the newly developed BCP showed favorable clinical, radiographic, postoperative discomfort-related, and early wound healing outcomes for peri-implant dehiscence defects that were similar to those for DBBM.
In a period from Sep 1994 to Sep 1996, 38 patients were treated for spontaneous pneumothorax by video-assisted thoracic surgery(VATS). 31 male and 7 female patients with ages between 17 and 79(mean 30.0 years). No death occured. The postoperative complication rate of VATS was 7.9%(3/38). We noted no recurrence of pneumothorax, 3 wound dehiscence, 3 persistent air leak(>7days) in the patients. We compared theses results with thoracoscopic surgery of spontaneous pneumothorax in 38 cases(Group A), with cases of 21 patients(Group B) performed by the thoracotomy in the same period. There have been no recurrence in groud A, and one recurrence in group B at a median follow-up of 14.37$\pm$7.48 months and 16.81 $\pm$7.12 months, respectively. There was no significant difference in the duration of operation time including induction time between VATS and thoracotomy, but postoperative hospital stay and chest tube drainage periods were all less for these undergone VATS. Postoperative complication was less in group A(3/38=7.9%, 3 cases with persistent air leak >7days, all developed wound dehiscence, too), than in group B(9/21=42.9%, 8 cases with persistent air leak more than 7days, including 2 wound dehiscence, one recurrence, and the other one case of empyema). In our experience, VATS has the effectiveness of thoracic surgery for treating thoracic problems, has resulted in surgical intervention in spontaneous pneumothorax.
