PURPOSE: Venous stasis ulcer is the most severe form of chronic venous insufficiency and this commonly appears in the lower limb. Pharmacological therapy, reconstruction of the venous system, surgical management, cellular therapy and compression therapy are known as the treatments of venous stasis ulcer, but relapses are common, which make it a typical chronic wound. We report here on a case of recurrent venous stasis ulcer that healed with compression therapy without any other treatment. METHODS: A 35-year-old man with a 13 years history of venous stasis had developed an ulcer on the distal third portion of the lower left limb which was developed 12-year before enrollment in this study. He had been treated with vacuum assist closure, 2 times of cell therapy and 3 times of skin graft for 8 years, but the lesion recurred. From November, 2008 compression therapy was done with the 3M Coban(TM) 2 Layer Compression System(3M, St. Paul, USA). The ulcer at that time was oval shaped and 3x4cm in size. A comfort layer bandage was applied from the proximal phalanx of the great toe to the knee. A compression layer bandage was applied on the previous layer with it being overlapped one half the width of the comfort layer bandage. The dressing was changed every 4 days and the change was recorded with photography. RESULTS: A total of 12 Coban(TM) 2 Layer Compression Systems were used. The size of the ulcer decreased to 2.5x2.5cm in one month, to 2x2cm in 2 months, it was 1x1.8cm in size at 3 months and it completely healed in 4 months. CONCLUSION: The venous stasis ulcer was completely healed using the 3M Coban(TM) 2 Layer Compression System. This method was easy to apply, made the patient comfortable and it provided an excellent compression effect. As in the previous studies, this compression therapy has been proven to play an important role for the treatment and prevention of venous stasis ulcer.

PURPOSE: The shape and location, the amount of the wound and the characteristics of the remaining tissues are known to influence wound contraction. The previous studies using small animals have not been an appropriate model because the wound healing mechanisms and skin structures are different from those of the human. The purpose of this study is to evaluate wound contraction according to the shape and location of the wound using a Micropig(R). METHODS: Four Micropigs(R)(Medikinetics, Pyeongtaek, Korea) that were 10 months of age weighed 25kg were used. Full thickness skin defects were made by clearing all the tissues above the fascial layer in the shape of square, a regular triangle and a circle of 9cm2 each on the back around the spine. Eight wounds were created on the back of each pig, 50mm apart from each other. The randomly chosen wound shapes included 11 squares, 11 regular triangles, and 10 circles. Wound dressing was done every other day with polyurethane foam. The wound size was measured using a Visitrak Digital(R)(Smith & Nephew, Hull, UK) on every other day after surgery from day 2 to day 28. A biopsy was performed on day 3, and 1, 2, 3 and 4 weeks to investigate the degree of acute and chronic inflammation, the number of microvesssel and myofibroblast density using H & E stain and immunohistochemistry. The wound contraction rate was calculated to figure out the differences among each of the shapes and the locations. RESULTS: The ultimate shape of the circle wound was oval, and that of the regular triangle and square were stellate. The maximum contraction rate was obtained on 8 to 10 days for all the shapes, which corresponds with the immunohistochemical finding that myofibroblast increases in the earlier 2 weeks whereas it decreases in the later 2 weeks. Epithelialization was seen in the wound margin on day 7 and afterwards. The final wound contraction rates were highest for the regular triangle shapes; however, there were no statistically significant differences. The wound contraction rates by locations showed statistically significant differences. The wound in the cephalic area presented more contractions than that of the wounds in the caudal area. CONCLUSION: The location of a wound is more important factor than the wound shape in wound contraction.

PURPOSE: The purpose of this study was to determine whether keeping the wound moist improves the results of composite grafting of amputated fingertip. MATERIALS AND METHODS: Between 1997 and 2010, 93 patients with traumatic amputation of 100 digits have undergone composite finger tip graft. The hand was kept elevated and a topical antibiotics was frequently applied to avoid desiccation. Their ages ranged from 10 months to 73 years. We assessed the success rate based on age, amputation level, ischemic time and etiology. RESULTS: Of these 100 composite grafts, grafting had been successful in 65. Evaluation by age revealed that grafting had been successful in 13 of 18 fingers among patients less than 6 years old, in four of five fingers among those 6 to 15 years old and in 48 of 77 fingers among those 16 years of age and older. Assessment by level of amputation showed that grafting had been successful in 37 of 56 fingers amputated in zone I, in 12 of 19 fingers amputated in zone II and in 16 of 25 fingers amputated in zone III. No statistically significant differences in graft survival were found in relation to age, amputation level, ischemic time or type of amputation. CONCLUSION: Our results demonstrate that composite finger tip graft in adult is feasible and a very high rate of survival is obtained. We believe that moist-exposed dressings should improve the success rate associated with fingertip composite grafting.

BACKGROUND: Facial hypoesthesia is one of the most troublesome complaints in the management of facial bone fractures. However, there is a lack of literature on facial sensory recovery after facial trauma. The purpose of this study was to evaluate the facial sensory recovery period for facial bone fractures using Neurometer. METHODS: Sixty-three patients who underwent open reduction of zygomatic and blowout fractures between December 2013 and July 2015 were included in the study. The facial sensory status of the patients was repeatedly examined preoperatively and postoperatively by Neurometer current perception threshold (CPT) until the results were normalized. RESULTS: Among the 63 subjects, 30 patients had normal Neurometer results preoperatively and postoperatively. According to fracture types, 17 patients with blowout fracture had a median recovery period of 0.25 months. Twelve patients with zygomatic fracture had a median recovery period of 1.00 month. Four patients with both fracture types had a median recovery period of 0.625 months. The median recovery period of all 33 patients was 0.25 months. There was no statistically significant difference in the sensory recovery period between types and subgroups of zygomatic and blowout fractures. In addition, there was no statistically significant difference in the sensory recovery period according to Neurometer results and the patients' own subjective reports. CONCLUSIONS: Neurometer CPT is effective for evaluating and comparing preoperative and postoperative facial sensory status and evaluating the sensory recovery period in facial bone fracture patients.
