Sirenomelia is a severe form of caudal regression syndrome that results in a fusion of the lower extremities, which is not compatible with life. A various spectrum of anomalies affecting primarily the musculoskeletal, genitourinary and gastrointestinal systems also can occur. This rare malformation has a reported incidence rate of approximately 1 in 60,000 births, with a range of 1 to 1 percent of all malformed infants. We experienced a sirenomelic case with combined anomalies of genitourinary, cardiovascular and gastrointestinal systems. Maternal obstetric history revealed oligohydramnios and intrauterine fetal growth retardation, and the baby was spontaneously delivered at 37 weeks of gestational age, but died I hour after birth.

Histologic changes suggesting HPV infection are occasionally found adjacent to squamous cell carcinoma or in squamous papilloma of the esophagus, but the relationship between HPV infection and benign and malignant squamous lesions of the esophagus is not yet dear. The aim of this study was to examine the role of HPV in squamous lesions of the esophagus. Microscopic examination with emphasis on HPV infection was done on 15 cases of squamous cell carcinoma and 26 cases of squamous papilloma. In situ hybridization technique for wide-spectrum HPV probe was performed on 35 endoscopically biopsied esophageal tissues. Among the histologic parameters suggesting HPV infection, acanthosis was the most frequent finding: 100.0% in benign and malignant esophageal lesions, and koilocytosis and intraepithelial capillary loops were the second (92.7%).: Dyskeratosis, basal cell hyperplasia and bi- or multinucleation were 52.3%, 44.0% and 34.1% in frequency, respectively. On in situ hybridization study, the HPV DNA expression rates of 10 squamous cell carcinomas with evidence of HPV infection and 15 carcinomas without evidence of HPV infection were 60.0% and 33.3%, respectively. In contrast to the carcinoma cases, only one (10.0%) of 10 squamous papillomas revealed positive signal. In conclusion, HPV infection is strongly associated with squamous cell carcinoma, but the causal relation of HPV to squamous papilloma is inconspicous.

p53 gene alterations in the ovarian cancers are regarded as early events in the whole process of carcinogenesis. This study is intended to compare p53 protein expression rate in the ovarian surface epithelial tumors according to histologic types, degree of malignancy and differentiation. 134 cases of ovarian epithelial tumors including 26 cases of serous cystadenoma, 7 cases of serous borderline malignancy, 15 cases of serous cystadenocarcinoma, 40 cases of mucinous cystadenoma, 21 cases of mucinous borderline malignancy, 20 cases of mucinous cystadenocarcinoma, 4 cases of endometrioid carcinoma, and 1 case of clear cell carcinoma were studied. Immunohistochemistry using monoclonal p53 antibody(DO-7) was applied to the routine formalin-fixed paraffin embedded tissue. The results were as follows; 1. No immunohistochemical positivity of p53 protein was found in all 66 cases of benign serous and mucinous tumors studied. 2. There was no significant difference of p53 protein expression between serous and mucinous malignant tumors. 3. The expression rate of p53 protein exhibited a statistically significant difference between borderline(42%) and malignant(74%) ovarian surface epithelial tumors (p<0.05). 4. The expression rate of p53 protein of poorly differentiated carcinomas(100%) was higher than those of moderately (88%) and well differentiated carcinomas(60%), but there was no statistical significance. In summary, p53 protein expression might be a good indicator of malignant transformation of the ovarian surface epithelial tumors.

Neuroblastoma occurs most frequently in children. It, however, may occur in adults. The peripheral neuroblastoma in adult is a primitive neuroectodermal tumor arising from peripheral tumor arising from peripheral nerve. It is exceedingly rare and estimated less than 1% of all malig-peripheral nerve tumors. We report a case of adult peripheral neuroblastoma arising in left lower extremity, who was treated with local excision and radiation.

Open reduction in an AO 33-A3 class distal femur transverse and comminuted fracture is often difficult due to frequent reduction loss during surgery, leading to longer operative time and increased blood loss intra-operation. In this study, the authors report a case in which the use of an offset grid plate (OsteoMed, USA) using 2.4 mm HPS (hand plating system) eased the process of fracture reduction and achieved a stable internal fixation, ultimately leading to successful osteosynthesis. The authors experienced no need for temporary fixation devices such as K-wires or screws, which are otherwise required to stabilize the reduction. The fracture reduction was stable throughout the primary fixation of the fracture using a locking plate and screws. The authors report that the advantage of the HPS plate is fitting into the cortical contour and providing stable maintenance of fracture reduction intra-operation, which would be beneficial in certain distal femoral fracture patterns.

Purpose: This study aimed to identify the effects of clinical nurses' ethical climate and ethical nursing competence on moral distress. Methods: The participants were clinical nurses who provided direct nursing care; nurses with more than one year of work experience in general hospitals were targeted. The data were collected between January 3 and 19, 2024, and analyzed using t-test, analysis of variance, Games-Howell test, Pearson correlation coefficient, and multiple regression. Results: Moral distress was significantly and negatively correlated with ethical climate and ethical nursing competence. Factors affecting the moral distress of clinical nurses included having a position of charge nurse or higher, total clinical experience of more than 20 years, turnover intention from current job due to ethical issues, hospital sub factors of the ethical climate, and ethical behavior sub factors of ethical nursing competence, showing 27.0% explanatory power. Conclusion Establishing a positive ethical climate and improving ethical nursing competence providing opportunities for nurses to raise and solve ethical issues will contribute to resolving nurses' ethical conflicts and reducing moral distress.
