BACKGROUND:The incidence of femoral head necrosis after internalfixation in femoral neck fracture is at highlevel, but the risk factors are stil under discussion. OBJECTIVE:To retrospectively propose and analyze the relative risk factors of femoral head necrosis after internal fixationwithfemoral neck fracture in patients younger than60years old. METHODS:Data from199 patients with femoral neck fractures,younger than60years,undergoingclosed reduction and internal fixation were analyzed retrospectively.Seven factors including age, sex, body mass index, Garden classification, fracture seasons, reduction quality and weight-bearing time after internal fixation were statisticalyanalyzedto evaluate their correlation with femoral head necrosis. RESULTS AND CONCLUSION:The incidence of femoral head necrosis was 13.1%amongthe199 cases. Body mass index, Garden classification, fracture seasons, reduction quality were significantly associated with femoral head necrosis. The age, sex and weight-bearing time wereinsignificantly associated with femoral head necrosis. In multivariate logistic regression analysis, Garden classification, reduction quality and fracture seasons (winterversussummer) hadoverteffectson development of femoral head necrosis. These results suggest that Garden classification and reduction quality make an important effect on the healing of femoral neck fracture. In addition, fracture in winter may be the risk factor of the femoral head necrosis after internal fixation in femoral neck fracture.

BACKGROUND: The regular use of soaps and synthetic detergents has been associated with skin dryness and aggravation of dermatological conditions. OBJECTIVE: Our purpose was to investigate the irritancy of 10 hand dishwashing liquids on normal skin. METHODS: The skin changes, responding to repeat patch testing with 10 hand dishwashing liquids, were measured by visual scoring. RESULTS: The results are summarized as follows; 1. Of the 16 healthy volunteers 8 had reactions. 5 women and 3 men, but there was no significant difference in irritancy between men and women. 2. The mean irritancy scores of the 10 hand dishwashing liquids ranged from 0.06 to 0.88. 3. A prominent increase in the degree of erythema in the first 24 hour patch test did not persist beyond exposure day 5, but after day 5, augmented responses of the erythema and scales, even fissuring occurred. 4. The pH of the test solutions of the hand dishwashing liquids ranged from 5.0 to 6.0, but there appeared to be no correlation between pH and irritancy in the dishwashing liquids tested. CONCLUSION: Our data suggests that regular exposure to hand dishwashing liquids may cause disturbances of the skin in a substantial proportion of individuals, and workers should use hand dishwashing liquids in lower concentrations than recommended and only for short periods with protective measures.

Of the 11 advanced bladder cancer patients who received M-VAC (Methotrexate, Vinblastine, Doxorubicin and Cisplatin) combination chemotherapy, complete and partial remission were observed in 63.6%. Of the 17 advanced bladder cancer patients who received MAC (Methotrexate, Doxorubicin and Cisplatin) combination chemotherapy, complete and partial remissions were observed in 17%. Complete remission was achieved in 18.2% of the patients clinically, pathologically in M-VAC group and 5.9% in MAC group. Partial remission was occurred in 46.5% of the patients in M-VAC group and 41.2% in MAC group. All metastatic sites including the bone and liver, lung were well responded in M-VAC group, but poorly responded in MAC group. Toxicity was significant but tolerable.

A case of a 21-year old female with Maffucci's syndrome is presented where the patient developed multiple cutaneous spindle-cell hemangioendotheliomas. She had multiple pea to walnut sized, non-tender, normal skin colored or slight bluish nodules and bony mass-like lesions on the left upper extremity and hand. A histological examination of the lesions showed that they were composed of irregularly dilated, thin walled cavernous blood spaces containing phleboliths and collapsed vascular spaces separated by spindled fibroblastic cells. Radiologically, the bony lesions showed radiolucent densities with calcified spots within the second proximal phalanx and metacarpal bone of the left hand, which were consistent with enchondromas.

PURPOSE: This study evaluated the initial stability of different implants placed above the bone level in different types of bone. MATERIALS AND METHODS: As described by Lekholm and Zarb, cortical layers of bovine bone specimens were trimmed to a thickness of 2 mm, 1 mm or totally removed to reproduce bone types II, III, and IV respectively. Three Implant system (Branemark System(R) Mk III TiUnite(TM), Straumann Standard Implant SLA(R), and Astra Tech Microthread(TM)-OsseoSpeed(TM)) were tested. Control group implants were placed in level with the bone, while test group implants were placed 1, 2, 3, and 4 mm above the bone level. Initial stability was evaluated by resonance frequency analysis. Data was statistically analyzed by one-way analysis of variance in confidence level of 95%. The effective implant length and the Implant Stability Quotient (ISQ) were compared using simple linear regression analysis. RESULTS: In the control group, there was a significant difference in the ISQ values of the 3 implants in bone types III and IV (P<.05). The ISQ values of each implant decreased with increased effective implant length in all types of bone. In type II bone, the decrease in ISQ value per 1-mm increase in effective implant length of the Branemark and Astra implants was less than that of the Straumann implant. In bone types III and IV, this value in the Astra implant was less than that in the other 2 implants. CONCLUSION: The initial stability was much affected by the implant design in bone types III, IV and the implant design such as the short pitch interval was beneficial to the initial stability of implants placed above the bone level.

MAGE (melanoma antigen gene) is a tumor specific shared antigen, presented by HLA class I molecules, which is recognized by cytotoxic T lymphocytes. MAGE proteins are expressed in malignant tumor cells, in contrast to no expression in normal or benign tissues except for testis and placenta. MAGE might be a potential target for immunotherapy of malignant tumors. However, its biological aspects associated with cell cycle are not yet described. The flow cytometry is a useful tool for objective and quantitative analyses of heterogenous tumor cell population. To understand the status of MAGE related to cell cycle and its relationship with p53 as the G1 checkpoint regulator, p21, and PCNA as a proliferative index, we investigated expression of MAGE-3 protein, mutant p53, p21, and PCNA by flow cytometry and immunohistochemical stain. In addition, double stains for MAGE-3/p53, p53/PCNA, and p53/p21 were analysed with bivariate flow cytometry. DNA histograms using MAGE-3/PI (DNA) and p53/PI (DNA) were also analysed. The cell line (PNUH- 12) used for this study originated from a hypopharyngeal squamous cell carcinoma, which has point mutation (exon 7, C-->G) of p53. The expression rate of MAGE-3 was 83%, PCNA 85%, and p53 81%. No expression for p21 was identified. MAGE-3 was expressed in cytoplasm, while both PCNA and p53 were expressed in nuclei of tumor cells. With bivariate analyses, coexpression rates of MAGE-3/p53 and p53/PCNA were 0.96 and 0.97, respectively. Both MAGE-3 and p53 showed constantly high level throughout the cell cycle. These results suggest that expression of MAGE-3 and mutant p53 is not dependent on the cell cycle. p21 seems to be inactivated.
