Purpose: To report the surgical skills needed, and the clinical results of, minimally invasive hip surgery with dynamic hip screws and the comparison with the classical technique in stable pertrochanteric fractures of the femur. Materials and Methods: Thirty-two patients with pertrochanteric fractures of the femur who were treated with dynamic compression hip screws between April 1999 and March 2004, and were evaluated retrospectively, and were followed up for more than 12 months. 16 cases were treated with a classical dynamic hip screw technique and 16 cases with a minimally invasive technique in random order. The mean age was 73.2 years, and there were 11 males and 21 females. The operative times, total hemovac bleeding loss, functional scores, and average hemoglobin decrease ratios were evaluated. The clinical assessments were performed with the Harris Hip Score (HSS) and bony union was evaluated with serial follow-up plain radiographs. Results: The average operative time was 63.9 minutes with the classical technique and 42.5 minutes with the minimally invasive technique. The total average hemovac blood loss was 640 cc with the classical technique and 143 cc with the minimally invasive technique. Clinically, the HHS was an average of 85.9 and 89.2 in groups 1 and 2, respectively, by the last follow-up and there were no statistically significant differences between the two groups (P <0.05) The hemoglobin decrease ratio was the same in both groups and there was no nonunion. Conclusion: Minimally invasive dynamic hip screw insertion was useful in stable pertrochanteric fractures, because it decreased blood loss and operative times; and there were no changes in fracture healing and functional outcomes.

BACKGROUND/AIMS: It has been reported that the difference in the hepatitis C virus (HCV) genotype due to genetic heterogeneity of HCV influence the clinical features, prognosis of HCV associated liver disease and response to interferon therapy. Prevalence of different genotypes of HCV may also vary between geographic areas. The aim of this study was to examine the relationship between the response to interferon alpha (IFN-a) therapy and HCV genotypes in patients with chronic HCV infection in Taegu and its environs. METHODS: One hundred seventy six patients known to be HCV antibody and HCV-NA positive were evaluated for HCV genotypes by restriction fragment length polymorphism. Among patients who had elevated ALT levels, 67 patients have been investigated for the role of the HCV genotype on disease outcome and the response of IFN-a therapy. RESULTS: Genotype 1b were found in 59.0% of patients (103/176), genotype 2a in 37.5% (66/176). The mode of transmission of HCV infection was guessed as transfusion in genotype 1b, but as parenteral infection in genotype 2a. According to their response to IFN-a therapy, 73 patients were divided into three groups, complete response, 18 (60%) of 30 patients with genotype 2a and 21 (48.8%) of 43 patients with genotype 1b: partial response, 5 (16.7%) of 30 patients with genotype 2a and 7 (16.2%) of 43 patients with genotype 1b: no response, 7 (23.3%) of 30 patients with genotype 2a and 15 (34.9%) of 43 patients with genotype 1b. Good response to IFN-a therapy was observed among patients group showing normal platelet count in patients with genotype 1b and normal GGT in patients with genotype 2a. CONCLUSIONS: The most frequently identified genotype was genotype 1b in Taegu and its environs, followed by genotype 2a. The HCV genotype was not a reliable predictor of response to IFN-a therapy. When a standardized regimen of IFN-a was administered, pretreatment serum platelet counts and GGT level seem to be useful predictor of IFN-a therapy in HCV infection. Further investigations are required in order to establish a correlation between viral factors and therapeutic responses.

BACKGROUND: Transforming growth factor (TGF)- has a large variety of biological functions, including the modulation of inflammation and the immune system, and is presumed to play important roles in repairing wounds and reducing scarring. The objective of this study is to examine the effects of TGF-1 on healing wounds and reducing scarring. We have also analysed the ability of the hemagglutinating virus of Japan (HVJ) liposome mediated antisense oligodeoxynucleotides (ODNs) to specifically inhibit wound-induced expressions of TGF-1 proteins and mRNA in the rat skin. METHODS: Skin wounds were created on the backs of 80 anesthetized rats. The first group of wounds, as the controls, was unmanipulated. The second group of wounds, as positive controls or an excessive scarring model, was injected with TGF-1 subcutaneously. The third group of wounds was injected with anti-TGF-1 antibody subcutaneously. The fourth group of wounds was injected with HVJ liposome mediated antisense ODNs for TGF-1 subcutaneously. The wounds of all groups were bisected and analysed histologically 5, 10, 15, 30, and 50 days after the wounds were made. RESULTS: All control wounds (TGF-1 or no injection) healed with scarring, whereas the wounds treated with the antibody or antisense ODNs healed with less scar formation compared to the control group. The wounds treated with the antibody or antisense ODNs had fewer macrophages, less collagen and fibronectin contents than the other wounds. Northern blotting and in situ hybridization analysis showed that wound sites treated with HVJ liposome mediated antisense ODNs for TGF-1 exhibited decreased levels of TGF-1 mRNA after injury. CONCLUSIONS: These findings suggest an important new approach to controlling scarring in normal wound healing, complementing the practice of adding exogenous growth factors to chronic wounds in the attempt to inhibit collagen deposition.

Corneal and conjunctival squamous epithelial cells have been known to express the mucin MUC1. We attempted to reveal the expression and localizational characteristics of the membrane-spanning mucin MUC1 as a component of the mucous layer in the human corneal epithelium. An antibody to the MUC1 was used to detect the MUC1 on the corneal epithelium by immunohistochemistry and immunofluorescent staining. In situ hybridization was performed to determine the distribution of MUC1 mRNA in the ocular surface. Immunohistochemically, the MUC1 mucin was observed along the apical membranes of the corneal epithelium. According to immunofluorescent staining, cells varied in the amount of mucin MUC1. Expression of MUC1 mRNA was observed in all layers of the corneal epithelium. The MUC1 mucin synthesized by the corneal epithelia exists on the apical membrane of the superficial cells. The amount of MUC1 may vary with the vertical migration and the activity of the cells.

Koilonychia is dystrophy characterized by eversion of the marginal portion of the nail. As a result, the central portion of the nail is concave. It has been associated with systemic or skin-related conditions. Hereditary koilonychia is inherited as an autosomal dominant trait. Koilonychia can also be caused by exogenous factors such as certain toxic chemicals or repeated mechanical trauma. In this case, koilonychia on the fingernail of the left thumb was caused by repeated trauma resulting from continuous suction since birth. Herein, we report a rare case of koilonychia induced by habitual thumbsucking.

In this study, we examined a case where lung cancer metastasized to the vulvar area. A 79-year-old woman that was a heavy smoker was referred to our department with a short (two-week) history of dyspnea, and with a painful nodule on her right labium majora, which she had noticed almost three years earlier. Histopathologically, the specimen appeared as a poorly differentiated squamous cell carcinoma. The chest X-ray, chest computerized tomography scan, and percutaneous transthoracic needle biopsy via bronchoscopy revealed squamous cell carcinoma in the right upper lobe of the lung. Based on these clinical and histopathological findings, we concluded that her condition was skin metastasis at the right labium majora from the lung cancer, which occurs very rarely.

Transforming growth factor-j31 (TGF-p1) has potential for therapeutic use in common clinical conditions for which there are no adequate pharmacological agents. However, in vivo studies using TGF-p1 were hindered by high price of this cytokine. As a first step towards large scale purification of TGF-p1, it was purified in a small scale (10 unit platelets) from human platelets by four purification steps: platelet extraction, gel filtration, cation exchange chromatography, and reversed phase high performance liquid chromatography (HPLC). A single protein band with a molecular weight of 25 Kd corresponding to purchased TGF-p1 (R8D Systems) was confirmed by silver staining after SDS-polyacrylamide gel electrophoresis (SDS-PAGE) of eluant from reversed phase HPLC. Recovery (%) of each step was about 50-60%, resulting in the final recovery of 20% based on the detection by a sandwich ELISA. Approximately, 3.7 p,g of purified TGF-p1 was obtained from 18 pg of platelet extracts. This result was confirmed by receptor (TGF-j31 type II) ELISA and bioassay using a mink lung epithelial'cell line (MV1LU). Further, in vitro characterization study showed that purified TGF-p1 inhibits G1/S transition of LPS-activated murine spleen B cells and increases surface IgA expression by the same cell population, which are typical activities of TGF-p1 in B cell differentiation. Taken together, the results from the present study reveals that purified TGF-p1 is fully biologically active and our purification methodology could be usbful to obtain a large scale of recombinant TGF-p1 in the future.
