  • Infection has assumed increased importance as a cause of death among thermally injured individuals. Decreased treatment effectiveness and an increase in mortality are the hallmarks of nosocomial infection. Infection control is a monumental task that must be achieved to reduce mortalities. This was a retrospective study to survey the epidemiological features of nosocomial infections in a burn unit and to identify the possibilities for infection control. During the past 6 year 2 month period from July, 1981 to August, 1987, 306 burn patients were treated in the burn unit of university hospital. Among of these, 290 cases were the subjects of this study. The data were collected from the patients' records after discharge. All data collected were analyzed using percent, x$^2$-test, t-test with SPSS program. The results of this study are summariged as follows: 1) Infection rate was 40%. According to site, there were 67 cases of wound infection, 60 cases of post-operative skin graft infection, 20 cases of septicemia and 20 cases of donor site infection. As far as the burn size was concerned, the infection rate for patients whose burn size ranged 61 to 70%, was shown to be 100%, followed by the infection rate of 93.8%, for patients whose burn size ranged from 41~50%. As far as the period of time over which the infection developed, 5 to 7 days showed the highest frequency. Further infection was the main cause of deaths and complications. 2) Based upon the results obained by comparing the general characteristics, between a hospital infection-group and non-hospital infection group, there was a significant defference according to age, the time of the year when the accident happened, the place of accident or length of hospital-admission. And according to the result obtained by comparing the general characteristics of the burn, there was a significant difference according to burn size, burn depth, burn type, and burn site. And also based upon the result obtained by comparing the two groups according to method of treatment, there was a significant difference according to the use of antibiotics and to the type of wound-treatment, and for the 8 different binds of treatment related to infection, there was a significant difference for all. In conclusion, age, length of hospital-admission, burn size, burn type, burn site, burn depth, type of woundtreatment and the 8 different binds of treatment, which are related to burns, were shown to be the factors which affect the infection rate in burn patients.

  • Guided bone regeneration (GBR) is a surgical procedure that utilizes bone grafts with barrier membranes to reconstruct small defects around dental implants. This procedure is commonly deployed on dehiscence or fenestration defects ≥2 mm, and mixing with autogenous bone is recommended on larger defects. Tension-free primary closure is a critical factor to prevent wound dehiscence, which is critical cause of GBR failure. A barrier membrane should be rigidly fixed without mobility. If the barrier is exposed, closed monitoring should be utilized to prevent secondary infection.

  • Purpose: The purpose of this study was to evaluate the surgical outcome of split-thickness skin graft (STSG) for chronic diabetic wounds of the foot and ankle. Materials and Methods: The medical records of 20 patients who underwent surgery for chronic diabetic wounds of the foot and ankle between October 2013 and May 2018 were reviewed. Surgical management consisted of consecutive debridement, followed by negative-pressure wound therapy and STSG. We used an acellular dermal matrix between the wound and the overlying STSG in some patients with wide or uneven wounds. Patient satisfaction, comorbidities, wound size and location, length of hospital stay, wound healing time, and complications were investigated. Results: Of 20 patients, 17 (85.0%) were satisfied with the surgical outcome. Eight patients had diabetic wounds associated with peripheral vascular disease (PVD), 7 patients had diabetic wounds without PVD, and 5 patients had acute infection superimposed with necrotizing abscesses. The mean size of the wound was 49.6 cm2. The mean length of hospital stay was 33.3 days. The mean time to wound healing was 7.9 weeks. The mean follow-up period was 25.9 months. Complications included delayed wound healing (4 cases) and recurrence of the diabetic wounds (2 cases), which were resolved by meticulous wound dressing. Conclusion: STSG remains a good treatment strategy for chronic diabetic wounds of the foot and ankle.

  • The purposes of this study were to Identify the .level of measurement on quality Indicators and evaluate the existing indicators in order to determine the priority of quality indicators' application in Korean general hospitals. A survey was conducted using a questionnaire. The subjects were quality managers working at general hospital having over 300 beds. The criteria were relevance, reliability, precision, impact, application, and preference to evaluate quality indicators. According to these six criteria, each indicator was evaluated on a five point scale(5: excellent, 1: poor). The response rate was $40.4\%$. The hospitals have monitored the average of 3.8 indicators(median 4). The indicators such as return to operating room, unplanned readmission, cancellation of booked operations, death, hospital infection, cesarean section rate, volume per disease or procedure, readmission, re-operation, blood transfusion, and post-procedural complications were frequently measured. The top ten quality indicators in the evaluation by its relevance, validity, reliability, impact, preference and application were decubitus ulcer, clean wound infection, fall, unplanned return to operation room, transfusion reactions, foreign body left In during procedure, unplanned readmission, wound infection after contaminated surgery, postoperative hemorrhage/hematoma, and cesarean section rate in order. The high priority quality indicators frequently measured could be used as primary national indicators. Standardized guidelines about monitoring indicators and the utilization will preliminarily be needed to compare and reuse the data for various purposes and improve the quality of care continuously.

  • The latissimus dorsi flap has high vascularity and is helpful for the reconstruction of infected areas. Herein, we present a patient with recurrent infections and soft-tissue defects who underwent cranial reconstruction using a free latissimus dorsi flap. The patient had undergone craniectomy and reconstruction using alloplastic bone 18 years previously. A scalp defect accompanied by infection occurred five years ago, and patient underwent reconstruction using a free flap at another hospital; however, the problem persisted. After debridement and bone flap removal, the right latissimus dorsi musculocutaneous flap was elevated, and the thoracodorsal artery and vein were anastomosed end-to-end to the right superficial temporal artery and vein. Methicillin-resistant Staphylococcus aureus was eradicated, and the flap survived. Cranioplasty was performed eight months later, and one year follow-up proceeded without complications. Effective reconstruction and cranioplasty are possible using the free latissimus dorsi musculocutaneous flap, even on scalp with persistent infections and soft-tissue defects.

  • Background The combination of polycaprolactone and hyaluronic acid creates an ideal environment for wound healing. Hyaluronic acid maintains a moist wound environment and accelerates the in-growth of granulation tissue. Polycaprolactone has excellent mechanical strength, limits inflammation and is biocompatible. This study evaluates the safety and efficacy of bio-conjugated polycaprolactone membranes (BPM) as a wound dressing. Methods 16 New Zealand white rabbits were sedated and local anaesthesia was administered. Two $3.0{\times}3.0cm$ full-thickness wounds were created on the dorsum of each rabbit, between the lowest rib and the pelvic bone. The wounds were dressed with either BPM (n=12) or Mepitel (n=12) (control), a polyamide-silicon wound dressing. These were evaluated macroscopically on the 7th, 14th, 21st, and 28th postoperative days for granulation, re-epithelialization, infection, and wound size, and histologically for epidermal and dermal regeneration. Results Both groups showed a comparable extent of granulation and re-epithelialization. No signs of infection were observed. There was no significant difference (P>0.05) in wound size between the two groups. BPM (n=6): $8.33cm^2$, $4.90cm^2$, $3.12cm^2$, $1.84cm^2$; Mepitel (n=6): $10.29cm^2$, $5.53cm^2$, $3.63cm^2$, $2.02cm^2$; at the 7th, 14th, 21st, and 28th postoperative days. The extents of epidermal and dermal regeneration were comparable between the two groups. Conclusions BPM is comparable to Mepitel as a safe and efficacious wound dressing.

  • Purpose: $Allevyn^{(R)}$(Smith & Nephew, England) is a type of polyurethane foam material with good wound discharge absorption. $Acticoat^{(R)}$(Smith & Nephew, England) is a silver coated dressing material which is effective in infected wound. The purpose of this study is to compare the effects of dry gauze, $Acticoat^{(R)}$ and $Allevyn^{(R)}$ on infected full-thickness wound healing in rat. Methods: One hundred and twenty rats were divided into 3 groups: group I(dressing with dry gauze, n=40), group II(dressing with $Allevyn^{(R)}$, n=40), group III(dressing with $Acticoat^{(R)}$, n=40). A $15{\times}15mm$ square full-thickness wound was made on the dorsum and left open for 24 hours. The size of wound defects were measured each dressing changes. The histological evaluation was performed on the 3rd day, 7th day, 14th day, 21th day. Results: After the wound was left open for 24 hours, typical findings of bacterial infection was observed. After the 7th day, group III showed larger area of epithelialization, smaller defect size compared to those of two other groups. Complete replacement by fibrotic scar tissue was observed in group III with no signs of inflammation on the 14th day. By day 21, the average defect size in group III was decreased from initial 100% to 3.63%. while in group I and II, it was decreased to 62.66% and 53.62%, respectively. Conclusion: $Acticoat^{(R)}$ is an effective tool in the treatment of infected wound.

  • Episiotomy is the commonest obstetrics intervention in the world to reduce severe perineal injuries. Its prevalence is 43% to 100% in primiparous women in Asia. Further, worldwide approximately 10-95% of pregnant women undergo episiotomy incision during birth. Delay in wound healing probably increases the risk of wound infection, changes the muscular structure, and ultimately causes muscle tone loss. So, wound care is of specific significance to postnatal maternal outcomes. Hence, this case study aimed to evaluate the effect of Marham-i-Raal in episiotomy wound healing and pain relief. The study was conducted in eleven postpartum primi or multipara pregnant women aged between group 19 and 35 years with term gestational age, singleton pregnancy in a cephalic presentation who had a normal vaginal delivery with mediolateral episiotomy, without a perineal tear, and perineal hematoma. Externally, application of Marham-i-Raal 2g on episiotomy incisional wound, twice a day for 10 days was advised. Wound healing of episiotomy and pain intensity was assessed with REEDA ["redness, oedema, ecchymosis, discharge and approximation of the edges"] scoring and VAS scoring for pain intensity respectively. At one hour (baseline), the REEDA mean score of eleven patients was 3.90±1.04 whereas on day 7-10 it was 0.18±0.40 with statistically significant difference (p<0.001). The VAS mean score at one hour was 6.90±1.22 whereas on day 7-10 it was 0.72±0.78 with a statistically significant difference (p<0.001). Marham-i-Raal would be effective in episiotomy wound healing and reducing pain intensity. Further, randomized double-blind controlled trials in large sample size are recommended.
