Congenital coxa vara is a rare congenital deformity, seen in infancy and childhood and the ratio of unilateral to bilateral is 3:1. The deformity does not become manifest until after birth and usually not until the age of walking. Pathologically, it consists of a progressively increasing acuteness of the neck-shaft angle;shortnees of the neck; a vertical direction of the epiphyseal plate; an oblique defect of the neck; a greater trochanter extending upward toward the ilium as a besk; a shortened femur; a secondary degenerative changese in the acetabulum due to malposition. We have experienced a case of bilateral congenital coxa vara treated with valgue osteotomy and the case review is presented.

Malignant fibrous histiocytoma has recently become an established diagnosis for some tumors that arise in the musculo-skeletal tissue. But it contains areas that resemble with osteosarcoma, fibrosarcoma, the microscopic lesions are composed of interlacing bands of fibroblast, bizzare histiocytes and multinucleated giant cells, arranged in storiform pattern. At present, the treatment advocated for malignant fibrous histiocytoma has been total surgical removal and radiation therapy. A case of malignant fibrous histiocytoma affecting the proximal tibia is reported with brief review of literature.

Purpose: This study aimed to investigate the potential role of copine-1 (CPNE1), a calcium-dependent membrane-binding protein encoded by the CPNE1 gene, in colorectal cancer (CRC). Despite previous research on the involvement of copine family members in various solid tumors, the specific role of CPNE1 in CRC remains poorly understood. Methods: We conducted clinicopathological analysis and functional studies to explore the impact of CPNE1 in human CRC.We examined the expression levels of CPNE1 in CRC patients and correlated it with invasive depth, lymph node metastasis, distant metastasis, lymphatic invasion, and TNM stage. Additionally, we performed experiments to assess the functional consequences of CPNE1 knockdown in CRC cells, including proliferation, colony formation, migration, invasion, and the expression of key regulators involved in the cell cycle and epithelial-mesenchymal transition (EMT). Furthermore, we evaluated the effects of CPNE1 knockdown on tumor growth using a xenograft mouse model. Results: High expression of CPNE1 was significantly associated with advanced tumor features in CRC patients. CPNE1 knockdown in CRC cells led to impaired abilities in proliferation, colony formation, migration, and invasion. Furthermore, CPNE1 silencing resulted in the suppression of protein expression related to the cell cycle and EMT. In the xenograft mouse model, CPNE1 knockdown inhibited tumor growth. Conclusion CPNE1 plays a crucial role in promoting tumorigenesis and metastasis in human CRC. By regulating the cell cycle and EMT, CPNE1 influences critical cellular processes at the membrane-cytoplasm interface. These results provide valuable insights into the potential development of novel therapeutic strategies for CRC targeting CPNE1.

BACKGROUND: Onychomycosis, especially toenail onychomycosis has become one of the common fungal infection and has historically been regarded as a cosmetic rather than medical problem by many patients, even by physicians. Recently, however, there are several reports that this is a refractory disease which may cause a deleterious effect on patients' quality of life (QOL). OBJECTIVE: The purpose of this study was to investigate the impact of toenail onychomycosis on QOL in Korea and to assess the changes of QOL after treatment. METHODS: Total 1004 patients with toenail onychomycosis which was confirmed by clinical findings and KOH preparation were enrolled at 47 dermatologic centers in Korea, and interviewed with standardized QOL questionnaire before and after systemic antifungal treatment. Responses to the questionnaire were scored by f-point scale (0~4) and averaged, and were analyzed for 5 dimensions of emotional impact, social impact, symptom and functional impact, patients' views concerning treatment, and relationship with doctor. RESULTS: 1. Before and after treatment, the most serious impact was emotional dimension showing 1.90 and 1.30 in average score (AS), and social (AS: 1.14 and 0.83) and symptom and functional impact (AS: 1.05 and 0.92) was also affected. 2. In female rather than male, statistically more significant impact on patients' QOL was observed in all dimensions. 3. After treatment, 3 of 5 dimensions were improved significantly - emotional dimension (AS: from 1.90 to 1.30), social dimension (AS: from 1.14 to 0.83), patients' view concerning treatment(AS: from 1.34 to 1.02) 4. The degree of patients' satisfaction at the therapeutic effect was very high - 62.4% (immediately after. treatment) and 65.8% (9 months after initiation of treatment) of patients answered excellent or good. CONCLUSION: This study confirms that toenail onychomycosis has significant Impact on the overall QOL of patients. Also the effect of antifungal therapy on patients' QOL were satisfactory. Therefore, both doctor and patient should pay more attention to the treatment of onychomycosis.
