Lentigo maligna melanoma and lentigo maligna are typically located on photo-exposed sites such as the head and neck, with the cheek being the most common site. Since lentigo maligna melanoma and lentigo maligna are found predominantly on such cosmetically-sensitive areas, it is critical to determine the exact histologic margin for maximal sparing of tissue and complete extirpation of the tumor. Since Mohs micrographic surgery has been recommended for tumors on cosmetically-sensitive locations where the tumor margin is indistinct, it appears to be a reasonable treatment modality for this type of tumor. We describe a case of lentigo maligna melanoma on the cheek, which was resected with Mohs micrographic surgery.

PURPOSE: Local skin necrosis after extravasation of adriamycin, a widely used chemotherapeutic agent, is a common problem in cancer patients. The extravasation of chemotherapeutic agents yields severe inflammatory responses, crust formation, skin necrosis, and ulceration. Even though several treatment options have been proposed for extravasation injury, there is still controversy regarding the management of such lesions. Thus the aim of this study was to compare the efficacy of saline injection (Group 1), hydrocortisone injection (Group 2), propranolol injection (Group 3) and early surgical excision as a treatment (Group 4) in a rat extravasation model. METHODS: The authors planned forty mature male Sprague-Dawley rats were divided into 4 groups and each group contained 10 rats. Administration of adriamycin (1.0 mg/mL) 1.5 mL by subcutaneous injection on the dorsal side of the rats was followed by protocol. The treatment options were applied 2 hours after adriamycin injection. At the end of the 5th day, the presence and size of ulcers at the injection site were checked. Three weeks after injection, a histopathologic examination was performed for each treatment and control group. T-tests were used to analyze the differences between the measurements. RESULTS: Propranolol significantly improved tissue recovery compared with control group and other groups. These data suggest that there is little role for saline and hydrocortisone in the treatment of adriamycin extravasation injury. CONCLUSION: In this study, we compared some treatment methods in adriamycin extravasation model. The findings support the propranolol injection may prevent extravasation injury. However this study was performed in the laboratory using rats, and the results could be different in clinical application. Further investigations and more clinical application are needed.

PURPOSE: Due to increasing interest in the treatment of spinal cord injuries, many histopathological studies have been conducted to prove that many neurotrophic factors including growth hormone are important for regeneration of the injured spinal cord. Growth hormone has to be given everyday, however, and this negatively affects compliance in clinical trials. Recently, the invention of sustained release growth hormone (SRGH) that can be given just once a week may both help the regeneration of injured spinal cord and, at the same time, be more compliant and convenient for clinical patients. METHODS: In this study, thirty 7-week-old female Spraque-Dawley rats were subjected to a weight-driven impact spinal cord injury. They were divided into 3 groups and Group I and II were injected with SRGH once a week for 4 weeks; Group I were injected into the injured spinal cord area, while Group II were injected into the peritoneal cavity. Meanwhile, Group III were injected with normal saline solution. The functional outcome was evaluated using the Basso-Beattie-Bresnahan motor rating score and the inclined plane test was done 4 weeks after the first injection. Histopathological examination was performed at the same time and the amount of residual white matter was measured in all groups. RESULTS: After 4 weeks, Groups I and II showed greater improvement than Group III(the control group) in the functional test. In the control group, invasion of atypical phagocytes, axonal degeneration, edema and cavity formation in the posterior site of spinal cord gray matter was observed in histopatholgical examination. The rate of residual white matter in Group III was less than in the other groups. CONCLUSION: Data showed significant functional and histopathological improvement in the groups treated with SRGH into the spinal and peritoneal cavity compared with the control group. SRGH is therefore beneficial because it helps with regeneration of the injured spinal cord and improves the compliance and convenience of patients.

PURPOSE: The number of sore patients are increasing steadily, especially in old ages, chronic disease and paralytic patients. Most of patients need to surgical treatment. The aim of this paper is to assess clinical analysis of surgical treatment and to consider operative methods, complications, and recurrences. METHODS: We reviewed the data from 82 consecutive patients with 101 pressure sores from March 2003 to May 2006 to discuss the occurrence rate and recurrence rate according to the site on the basis of the presence or absence of paraplegic and its etiology-the patients were categorized into three diagnostic groups: traumatic paraplegics(TP), nontraumatic paraplegics (NTP), and nontraumatic nonparaplegics(NTNP). We examined the sites and sizes of each lesions, patient's state, primary causes of pressure sore, operative methods as each sites and groups, occurrence of complications and recurrences on each groups. RESULTS: In 82 patients, 52 patients were male, 30 patients were female. The male to female ratio was 1.7 :1. Mean age was 55.8 years. 27 patients were in TP group, 35 in NTP group, and 20 in NTNP group, respectively. The common site of sore were sacral area (50.5%), greater trochanteric area(15.8%) and ischial area(13.9%). In each group, incidence rate of recurrence and complication were 11.1%, 40.7% in TP, 5.7%, 5.7% in NTP and 15%, 45% in NTNP. CONCLUSION: Surgeons must consider the general condition of the patient and possibility of recurrence and returning of daily life. We propose that cutaneous flap, fasciocutaneous flap or skin graft as well as musculocutaneous flap be useful to repair of sore site as each patient's state.

PURPOSE: Human adipose tissue-derived mesenchymal stem cells(hATSCs) can be differentiated into multiple mesenchymal lineages, including bone, cartilage, and muscle. And growth hormone play important roles in the normal growth and development of the CNS. In this study, we explored whether the transplanted hATSCs and growth hormones could improve functional recoveries from rats with contusive spinal cord injury. METHODS: We divided 30 female rats, which were subjected to a weight driven implant spinal cord injury, into 3 groups with 10 rats each; Group A as a control group, group B with hATSCs transplantation on injured region, and group C with hATSCs transplantation and GH administration for 7 days. Then, we researched their neurologic functional recoveries before and 2, 4, and 8 weeks after transplantation using Basso-Beattie-Bresnahan (BBB) locomotor rating scale. And we checked Y- chromosome positive cells by FISH(Fluorescent in situ hybridization) to identify the survival of transplanted mesenchymal stem cells. RESULTS: After 4 weeks of transplantation, the group B and group C showed significant improvement of neurologic function on BBB locomotor rating scale in comparison with the group A(Group A: 13.1+/-0.58, Group B: 14.6+/-0.69, Group C: 14.9+/-0.56). Moreover, the group C displayed meaningful recovery of neurologic function after 8 weeks in comparison with group B (Group B: 15.7+/-0.63, Group C: 16.5+/-1.14). The group A, the control one, improved for 5 weeks after injury, and had no more recovery. On the other hand, Group B and C showed the improvement of neurologic function continuously for 9 weeks after injury. CONCLUSION: In this study, we found out that hATSCs transplantation have an effect on neurologic functional recovery of spinal cord injured rat and GH injection seems to bring the synergistic results on this good tendency.

PURPOSE: Materials for ear reconstruction are autogeneous cartilage and artificial implants. Despite their potential for donor site complications, autogeneous cartilage frameworks remain the accepted standard for external ear reconstruction. The purposes of this study were to investigate our ear reconstruction cases for 12 years. METHODS: During twelve years from January 1996 to December 2008, 70 patients visited our hospital for ear reconstruction of microtia. Among them, 65 cases used autogenous cartilage frameworks, 3 cases used tissue expander and 2 cases used artificial implants. We investigated sex & age, common site, combined malformation, operation methods & their complications, donor site & their complications, anterior chest wall deformity and aesthetic evaluation. RESULTS: Males were affected more often than females. Male to female ratio was 1.8:1. The common site of microtia was right ear(72%). And hemifacial microsomia was the most common associated congenital malformation. Surgical techniques included Tanzer-Ruecker method, Tissue-expander and Artificial framework(Medpore(R)). Incidence of complication was higher with Tissue-expander & artificial framework than with Tanzer-Ruecker method. But There are few reports of using Tissue-expander & artificial framework and there was no acceptable statistical difference. And costal cartilage was harvested in ipsilateral side and anterior chest wall deformity reported only 2 cases under 10 year-old patients. Other minor complications reported such as, wound disruption and chest wall scar, but without any serious complications. Aesthetic result was evaluated by surgeons and patients for postoperative satisfaction and clinical evaluation. CONCLUSION: In ear reconstruction of microtia patient, delicate surgical strategy is important for natural shape and maintenance of postoperative contour. However, many methods were introduced for reconstrucion of microtia, the authors reconstructed an auricle in Tanzer-Ruecker method, Tissue-expander and Artificial famework(Medpore(R)) for 70 patients. In our study, we generally chose Tanzer-Ruecker method and this treatment modality was satisfactory for patients and the postoperative result was acceptable for surgeons.
