The primary goal in the treatment of the nail bed avulsion injury is complete regrowing of the nail plate without any deformity. There are many procedures for treatment of the nail bed avulsion injury as a split-thickness skin graft, full-thickness nail bed graft, reverse dermal graft or split-thickness nail bed graft. From February, 1984 to June, 1985 at In-Chon Gill Hospital, 13 cases of nail bed avulsion injury were treated with split-thickness nail bed grafts. The intact residual part of the injured nail bed or the toe nail bed was served as a donor site. The results were as followings; 1. The incidence of nail bed avulsion injury of all hand injuries was 9.7%. 2. The main cause of injury was the industrial accident and more prevalent in the left hand. 3. The good result was obtained in the split-thickness nail bed graft for the nail bed avulsion injury, but in nail root portion, the poor result was noticed. 4. The average time for normal nail appearance is six months.

3.Clinical Experience of Male Pseudohermaphroditism.

Although the definition of male pseudohermaphroditism remains controversial, male pseudohermaphrodites will be defined as chromatin-negative individuals who have testis with the failure of normal development of the normal male. Also included are those individuals who may have more than one cell line, but at least one cell line, containing a Y chromosome and no cell line having two X chromosomes. Gonadal histologic findings may be either testicular or streak, but not ovarian. Male pseudohermaphroditism can result as a consequence of 1) absent M(llerian regression, 2) Inadequate synthesis of testosterone, 3) inadequate synthesis of dihydrotestosterone and 4) androgen receptor deficiency. We have seen 5 cases of male pseudohermaphroditism with manifestations of penoscrotal or perineal hypospadias, pubertal virilization, cryptorchism or atrophied testes, and feminization. Four cases had been reared as male and one case as female. All revealed chromatin-negative pattern in buccal smear and testes. After the plausible discussion, two cases were decided to be reared as female and three were as male.

4.Axial Stiffness of the Ilizarov Frame Using the Rancho Mounting Technique.
The Journal of the Korean Orthopaedic Association 1998;33(7):1928-1932
The Ilizarov fixator allows significantly more axial motion at the fracture site than the conventional monofixators. But the transfixing wires have inevitable problems of soft tissue impalement. Therefore the Rancho mounting technique, replacing the transfixing wires with half pins, has become a common place. But the increment of the axial stiffness secondary to replacing transfixing wires with half pins has not been defined clearly yet. The authors measured the axial stiffness of the Ilizarov fixator and two different configurations of the Rancho frame. The group I frame was the Ilizarov fixator composed of four rings and two transfixing wires on each ring. The group II frame was the Rancho frame and it was constructed same as the Ilizarov frame but a transfixing wire was replaced with a half pin from two central rings respectively. The group III frame was another type of Rancho frame which was constructed same as the second group but the remaining transfixing wire was replaced with a half pin from the two central rings respectively. The axial stiffness of the Group I , II and Group III frames were 71.54+/-7.21N/mm, 89.65+/-6.42N/mm, 101.01+/-7.92N/mm respectively. The axial stiffness difference between the Group I frame and the Group II frame was statistically significant(p<0.01). Also the difference between the Group I frame and the Group III frame was statistically significant(p<0.01). This study shows that the replacement of two transfixing wires with two stainless half pins resulted in significant increment of the axial stiffness of the Ilizarov frame.

Pedunculated lipofibroma is a rare disorder characterized by ectopic deposits of mature adipose tissue in the dermis. It is a dorne shaped or sessile papule which occurs at any site and develops later in life. We, herein, report two cases of pedunculated lipofibroma which have developed on the chin of a 64-year-old man and the buttock of a 47-year-old woman.

PURPOSE: This study was conducted to investigate the epidemic pyrogenic reactions that occurred hospital-widely in 51 patients on 30-31 Mar. 1995 at a tertiary, educational, and acute care hospital. METHODS: The remained intravenous (IV) drugs and IV fluids that were infused to patients (N=51) who developed pyrogenic reactions were cultured and tested pyrogenic matter. Pyrogenic test was done by Limulus Amebocyte Lysate (PyrotellRMA,USA). RESULTS: IV normal saline 50 cc bottles (AAXSAT and AAX5AV) those were collected being used from case patients, and new bottles stocked in the drug storage were positive to pyrogenic test. Used normal saline collected from case patients were cultured coagulase-negative Staphylococus. Moreover the company, manufacturer of these fluids reported the positive pyrogenic test on these IV fluids (AAXSAT and AAX5AV). CONCLUSION: This epidemic was a pyrogenic reaction for infused the intrinsic contaminated fluid with pyrogen. We could prevent not the additional pyrogenic reactions in study hospital but national wide epidemics to apply the rapid and well-designed epidemic investigation and infection control.

Human lymphoblastoid B-cell lines immortalized by Epstein-Barr virus (EBV) were established from peripheral blood of patients with acute myeloblastic and chronic lymphocytic leukemia and chronic fatigue syndrome. The sera of patients with acute myeloblastic and chronic lymphocytic leukemia did not show antibodies to Epstein-Barr viral capsid antigen (VCA), but serum of a patient with chronic fatigue syndrome disclosed antibodies to VCA (IgG, IgM), and EBNA was demonstrated in peripheral blood mononuclear cells by polymerase chain reaction. The established cell lines were mature B-cell phenotypes with polyclonal proliferation in early passage and no evidence for commitment to other lineages. The immortalized cells by EBV were designated as CSUP-1 and CSUP-2 (from acute myeloblastic leukemia, FAB classification M2 and M1), CSUP-3 (from chronic lymphocytic leukemia) and CSUP-4 (from a patient with chronic fatigue syndrome). The CSUP-1, 2, 3, and 4 grew in suspension forming clumps with a doubling time of 38 to 49 hours. Colony formation was not recognized in plate. By light and electron microscopic examination, the immortalized cells showed features of lymphoblastoid to plasmacytoid lymphocytes, and multinucleated giant cells. The lymphoblastoid cells showed scanty cytoplasm with poorly developed organelles. Immunophenotypic analyses of CUSP-1, 2, 3, and 4 with monoclonal antibodies by flow cytometry showed B-cell phenotype with polyclonal proliferation in early passage. Epstein-Barr virus nuclear antigen was confirmed in the extracted DNAs from immortalized cells by polymerase chain reaction. DNA analysis showed a normodiploid stemline with a DNA index of 1.12. The established cells were strongly reactive for CD10, CD30 (Ki-1) in early passage, and bcl-2 and c-myc onco-protein in early and late passage. Karyotypic analysis of CSUP-1, 2, 3 and 4 showed 46, XY or 46, XX. No tumorigenesis in heterotransplanted SCID mouse was recognized. This immortalized cells by EBV should be a valuable cell lines to study the pathogenesis of EBV-related malignant lymphoma.
