A seven-year-old, castrated male, Korean domestic shorthair cat was referred because of a kidney abnormality. Radiography revealed left renal agenesis and right kidney enlargement. Ultrasonography and computed tomography (CT) showed amorphous calcified materials in a cyst-like lesion of the right kidney. In the excretory phase of the CT images, the lesion was opacified with contrast material, indicating communication with the collecting system. Based on these findings, the cat was diagnosed with a calyceal diverticulum. A calyceal diverticulum may cause various clinical symptoms related to the urinary system. The excretory phase of CT is useful for diagnosing a calyceal diverticulum.

PURPOSE: The purpose of this study was to compare smoking prevalence and risk factors of smoking between Korean and Korean-Chinese middle school students. METHODS: Data was collected from seventh and eighth grade students from 12 schools in Korea and 6 schools in China. Descriptive statistics, Chi-square test, and t test were performed. RESULTS: For data analysis 10,002 usable surveys were utilized. The smoking prevalence was higher in Korean-Chinese students than in Korean students. Risk factors, such as father smoking, friends smoking, gender, grade, academic achievement, alcohol use, and family income were associated with current smoking, and the differences in the two samples were significant. Korean-Chinese students were more likely than Korean students to have friends who smoked and a father who smoked. Smokers had a significantly higher rate of friends smoking, father smoking, and alcohol use. Korean-Chinese male students smoking prevalence was more than three times higher than Korean students. Korean students could sense a more anti-tobacco atmosphere in their environment. Korean-Chinese students were more likely than Korean students to perceive that it was easy to buy cigarettes and to smoke cigarettes in a public computer room. CONCLUSION: These results highlight the differences of smoking prevalence and risk factors between Korean-Chinese students and Korean students. The findings may help health educators and researchers to better understand adolescent smoking and risk factors cross culturally and aid in the development of more effective education programs, which could lead to preventing tobacco use among these populations.

PURPOSE: This study was to analyse the factors affecting youth smoking, especially self-efficacy and perceived social norm, based on the stage of change. METHODS: A self-reported survey was conducted during the period from the 21st of April to the 17th of May, 2008. Data were collected from 10,707 students of 12 middle schools in Seoul, Gyeonggi-do, and Incheon. The data were analysed with SPSS/WIN 15.0. RESULT: The smoking possibility was 2.18 times higher in the male students than in female students, and 1.76 times higher in 8th-grade students and 2.48 times higher in 9th-grade students than in 7th-grade ones. Smoking possibility increased when students had more experience in alcohol, more friends who smoke, or worse relationship with their parents. Also this study showed that high-level self-efficacy and perceived social norm were acting as inhibiting factors of smoking. CONCLUSION: To reduce the youth's smoking rate, smoking prevention programs should provide educational chances to learn knowledge and skills on how to reject smoking temptation. Also, someone significant like parents should make it clear to the youth that they do not want their children to smoke.

Background: Pure mucinous carcinoma (PMC) is a rare type of breast cancer, estimated to represent 2% of invasive breast cancer. PMC is typically positive for estrogen receptors (ER) and progesterone receptors (PR) and negative for human epidermal growth factor receptor 2 (HER2). The clinicopathologic characteristics of HER2-positive PMC have not been investigated. Methods: Pathology archives were searched for PMC diagnosed from January 1999 to April 2018. Clinicopathologic data and microscopic findings were reviewed and compared between HER2-positive PMC and HER2-negative PMC. We also analyzed the differences in disease-free survival (DFS) and overall survival according to clinicopathologic parameters including HER2 status in overall PMC cases. Results: There were 21 HER2-positive cases (4.8%) in 438 PMCs. The average tumor size of HER2-positive PMC was 32.21 mm (± 26.55). Lymph node metastasis was present in seven cases. Compared to HER2-negative PMC, HER2-positive PMC presented with a more advanced T category (p < .001), more frequent lymph node metastasis (p = .009), and a higher nuclear and histologic grade (p < .001). Microscopically, signet ring cells were frequently observed in HER2-positive PMC (p < .001), whereas a micropapillary pattern was more frequent in HER2-negative PMC (p = .012). HER2-positive PMC was more frequently negative for ER (33.3% vs. 1.2%) and PR (28.6% vs. 7.2%) than HER2-negative PMC and showed a high Ki-67 labeling index. During follow-up, distant metastasis and recurrence developed in three HER2-positive PMC patients. Multivariate analysis revealed that only HER2-positivity and lymph node status were significantly associated with DFS. Conclusions Our results suggest that HER2-positive PMC is a more aggressive subgroup of PMC. HER2 positivity should be considered for adequate management of PMC.
