The autogenous fascia graft has been used for various surgical purposes because it has good durability, a gliding capacity, elasticity and a high survival rate. However, few studies have reported histological changes of the graft in various situations. This study attempted to determine histomorphologic changes after autogenous fascia graft in various surgical conditions. The results revealed were as follows: 1. The tension applied to grafts plays the key role in the survival rate of autogenous fascia grafts. 2. Rolling the fascia reduced the volume and weight after autogenous graft due to fibrosis and central fatty degeneration. 3. Autogenous fascia graft covering silicone blocks showed its fascial structure and reduction of the formation of fibrous capsule around the silicone.

A case of congenital self-healing histiocytosis was studied with S-100 antibody and electron microscopy. Many tumor cells were positive for S-100 protein and a few contained Birbeck´s grandles and dense bodies. A pathlogic fracture was first noticed on the seventh day. The lesions involuted spontaneously by the end of a weeks

A 40-year-old woman had a pruritic, vesiculobullous eruption of her face for 6 weeks with no evidence of systemic disease. A biopsy showed subepidermal blisters and dermal infiltrates of neutrophilic inflammatory cells. Direct immunofluorescence demonstrated thick linear deposits of IgG and C3 along the basement membrane zone. The cleavage plane was identified to be just beneath the lamina densa. Using Western immunoblots, the patient's IgG autoantibodies were found to recognize type VII proeollagen. Moderate starting doses of systemic prednisolone gave a good response for this patient with an early inflammatory form of epidermolysis bullosa acquisita.

A 79-year-old man with balanitis circumscripta plasmacellularis(BCP), presenting as an erythematous constricting band of the inner surface of the prepuce encircling the penile shaft is described. The biopsy specimen of the lesion showed, in addition to the typical histologic findings of BCP, increased fibrosis and decreased amount of elastic fibers which correlate well with our clinical observations. Electron microscopic examination revelaed no viral particles or elastic fibers. Immunohistologically, IgG was found to be the major immunoglobulin class in the plasma cellular inf iltrate.

Whiplash injury in low-speed traffic accidents are not objectively verified by medical equipment, thereby creating scope for misuse, which has resulted in huge social losses worldwide. The aim of this study was to examine the influence of low-speed vehicular rear-impact collisions on middle-aged men, and to analyze the head and neck injury criteria for the symptomatic human volunteers. Data was examined from the results of 50 dynamic sled tests, originally performed by Hong et al. (2012). In the previous tests, 50 men aged 30~50 years were exposed to an impulse equivalent to a bumper-to-bumper rear collision under medical supervision, and no resulting whiplash injury was identified. In this study, for 6 subjects who experienced dull aches over their bodies, head injury criteria (HIC15) and neck injury criteria (N(km)) were calculated according to the accelerations, forces, and moments at the occipital condyle measured by motion capture system. Although there were no changes in magnetic resonance imaging findings in all subjects at the pre-/post-test orthopedic examination, 6 subjects revealed mild aches around the shoulder, back, or lumbar area, and their symptoms disappeared within 2 days. The head and neck injury criteria, HIC15 (3.086 +/- 2.942) and N(km) (0.077 +/- 0.064) were obtained, and the maximum HIC15 and N(km) were found to be significantly lower than the critical injury assessment reference values (HIC15: 700, N(km): 0.3). Moreover, even though 2 subjects were exposed to the same level of change of velocity (7.9 km/h), each N(km) was significantly different (0.179, 0.057). One can therefore conclude that N(km) can vary according to voluntary movements in the human subject.

Twenty four patients with gap nonunions of the tibia were treated with the Ilizarov intercalary bone transport method. The purpose of this retrospective study is to evaluate the results and complications in gap nonunions of the tibia treated using the Ilizarov method. There were 22 males and two females with an average age of the 35.8 years(range, 23-63 years). The mean follow up period was 30.2 months(range, 17-70 months). Ten of the 24 patients had no external shortening with bone gap, 13 external shortening with gap and one hemicircumferential defect. On average, the size of bone loss measured 8.2 cm(range, 3-18 cm). Twenty-one of 24 patients were treated by whole segment internal transport(fifteen were proximal fragment transport, five were distal fragment transport, one was proximal and distal fragment transport), one patient by anterior hemicircumferential corticotomy and partial bone fragment internal transport and tow patients by fibula transfer. All patients healed with solid bony union, although twelve patients required bone grafts, eleven at the docking site and one at the distraction site. On average, the healing index was 49 days/cm(range, 18-82 days/cm). There was on relationship between the percentage transport(size of the distraction gap/the transporting fragment length x 100) and healing index. Numerous complications were encountered, most commonly delayed union and pin site infection, Conclusively, the application of Ilizarov techniques to gap nonunions of the tibia was very effective, but required correct technique and careful follow-up examination.
