Hyperkeratosis of the renal pelvis and ureter is a rare condition and is explained by the metaplastic change from transitional to cornified squamous epithelium. This lesion is frequently associated with, and perhaps caused by chronic urinary infection, but potentially premalignant, accompaning with carcinoma in about 10 to 20 per cent of the cases at the time of diagnosis. A case of hyperkeratosis of renal pelvis & ureter which was clinically suspected of carcinoma in a 49-year old woman with a long history of chronic pyelonephritis is presented with review of literature.

Adenosquamous carcinoma of stomach is a mixed glandular-epidermoid tumor where both components are neoplastic. Its incidence is extremely rare. The five theories on the origin of squamous components are 1) island of ectopic squamous epithelium in the gastric mucosa, 2) squamous metaplasia of gastric epithelium, 3) squamous differentiation in a preexisting adenocarcinoma, 4) endothelial cell differentiated toward squamous elements, and 5) totipotential undifferentiated cells of the gastric mucosa. We experienced three cases of adenosquamous carcinoma. Case 1 was a 71-year-old female patient; an ulcerative lesion was present in the pylorus, measuring 5 cm in diameter. Case 2 was a 57-year-old male patient; an ulcerative lesion is present in the pylorus, measuring 6 cm in diameter. Case 3 was a 58-year-old female patient; an ulcerative lesion was present in the body and fundus, measuring 10 cm in diameter. Microscopic examination revealed a mixed malignant squamous and adenomatous component.

or =50 years), there was a significant association between oral cancer risk and high BMI in female subjects younger than 50 years of age (OR=3.92, 95% CI 1.03~14.9, P for trend=0.04), but not in older (> or =50 years) female subjects (OR=1.11, 95% CI 0.55~2.24, P for trend=0.76). There was no significant relationship between BMI and oral cancer risk in any of the male age subgroups.CONCLUSION: Our study provides the first epidemiological evidence supporting an association between obesity and an increased risk of oral cancer.]]>

PURPOSE: This study aims to develop a tool to predict occupational health patients' nursing needs or nursing time. METHOD: A tool was composed based on the materials and opinion of experts, and to verify the reliability and validity of the tool, nursing time of total 311 inpatients in 2 occupational health hospitals were surveyed. RESULTS: The developed tool was total 151 items and composed of physical function, cognitive function, communication, emotional and disturbance behavior, nursing skill, and rehabilitation need. The reliability of the tool was high, showing Cronbach's alpha coefficient of 0.95. But several items should be deleted for low corrected item-total correlation. According to the multiple regression analysis, physical function and rehabilitation need were shown to be the most powerful predictive variables for nursing time. CONCLUSION: The developed tool was appeared to have high reliability and validity. But further refinement of the tool is needed.

Because melanocytes are found throughout the leptomeninges, primary melanotic pigmented tumors such as pigmented meningioma, malignant melanoma, melanoblastosis, and melanocytoma can arise from this region. Melanocytomas have been described in the literature as isodense or hyperdense compared with brain parenchyme, as seen on noncontrast-enhanced CT, and as showing relatively homogeneous enhancement. MR imaging demonstrates a high signal on T1-weighted images, and an iso to hypointense signal on T2- weighted images. We report the imaging findings of a melanocytoma that showed hyperdense attenuation on precontrast CT with homogeneous enhancement and hyperintense signal intensity on T1-weighted images and dark signal intensity enhancement on T2-weighted images, and also review the literature.

PURPOSE: The purpose of this study was to construct and test a structural equation modeling on the reproductive health behavior of single women with sexual experiences. This study employed Ajzen's Theory of Planned Behavior (TPB). METHODS: The data were collected after receipt of consent from 250 single women with sexual experiences, and analyzed using SPSS 18.0 and AMOS 18.0. RESULTS: Model fit indices for the hypothetical model were suitable for the recommended level: x²=362.407, RMR=0.065, RMSEA=0.070, GFI=0.867. TLI=0.927, CFI=0.938, IFI=0.939, and x²/dF=2.237. Intention showed direct effect with the biggest effect being on reproductive health behavior. Attitude, subjective norm and perceived behavioral control were found to have a direct effect on intention. Among them, perceived behavioral control revealed the largest influence. CONCLUSION: This study suggests that the TPB is a suitable model in explaining the reproductive health behavior of single women with sexual experience. Strategic plans for educational and intervention programs should be aimed to encourage single women to engage in reproductive health behavior.

The primary malignant melanoma of the nasal cavity and paranasal sinuses is extremely rare and accounts for only between 0.6 and 2.5% of the total number of malignant melanoma at all sites. In the nose, the left side is involved in 60% of cases and the most frequent site is the septum followed by the inferior and middle turbinates. In the sinuses, the maxillary sinus is the site of origin 80% of cases, followed by ethmoid sinus. The tumors are sessile or polypoid, with variable color such as pink, white, brown or blank. Of all tumors, 10-30% are amelanotic, requiring special stains for melanin. When primary site of melanoma is mucosal origin, treatment of primary lesion is often hampered by anatomic restrictions and large size, which results from the delayed diagnosis caused by their location. We report 4 cases of primary malignant melanoma of nasal cavity with review of literature.

PURPOSE: The purpose of this study was to investigate the actual condition of the disabled due to Occupational accidents based on the functional evaluation tool. METHOD: The data were collected from 2 Workers Accident Medical Corporation, 311 subjects between February and August, 2007. The tool comprised of six components including physical function, cognitive function, communication, emotional and disturbing behavior, nursing skills and rehabilitation needs. RESULTS: Among the disabled, the average point of physical function of 5 was found in 61.92% and to express and understand were evaluated as normal in 36.69% and 33.44%, respectively. Also, hearing and vision were evaluated as normal in 53.50% and 37.98%, respectively. 19.01% of the disabled had emotional problems and 13.78% had disturbing behavior. Most disabled were in need of nursing skills with 97.73% ROM and activities. The 78.18% and 76.90% of disabled were in need of rehabilitation because of right and left leg in full movement disorders, respectively. CONCLUSION: The evaluation score for the disabled caused by Occupational accidents was diverse showing 10 to 19 points and 140 to 150 points. The result means the care cost should be determined depending on the care needs of the disabled because there is such a diverse range of care needs for them.
