This study was performed to investigate the relationship between milk and milk product consumption and dietary nutrient intake among Korean adolescents. Questionnaire survey and 3-day diet survey using the food record method were completed by a total of 664 subjects. Subjects were divided into three groups, Q1 (low group), Q2 (middle group), and Q3 (high group), according to dairy equivalent of calcium. Dairy equivalent of calcium was determined by the amount of calcium eaten from milk and milk products by individual subjects. As a result, the ratio of school milk service was higher in Q3 (P<0.001). The most frequent answer about the reason for consuming milk and milk products was 'to be taller' followed by 'good taste' and 'health promotion'. Preference for all types of milk such as white-, enriched-, and flavored- milk was higher in Q3 followed by Q2>Q1 (P<0.05). Ratio of mean daily dietary nutrient intakes of dietary fiber, vitamin C, folate, and calcium to RNI was lower than 2/3 for all of the groups. These mean daily dietary nutrient intakes were significantly higher in Q3 (P<0.05), and in particular, mean daily dietary calcium intake, which was the lowest nutrient consumed by Korean adolescents, was also the highest in Q3 followed by Q2>Q1 (P<0.05). The above results suggest that the school milk program is very helpful in encouraging adolescents to consume milk and milk products and consequently ensure their optimal nutrition. Therefore, we should try to encourage adolescents to participate in the school milk program more actively through nutritional education and government policy.

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) and extensively drug resistant tuberculosis (XDR-TB) are serious threats to worldwide tuberculosis control, but the national burden and the trends of infectious spread are largely unknown. METHODS: We retrospectively reviewed the results of drug sensitivity tests and medical records of patients that were diagnosed with culture-confirmed pulmonary tuberculosis and were admitted to the National Masan Tuberculosis Hospital between 2001 and 2005. RESULTS: From 2001 to 2005, the proportion of MDR-TB among new cases was 9.2%, 13.8%, 16.9%, 23% and 27.0% in 2001, 2002, 2003, 2004 and 2005, respectively, and the proportion of MDR-TB among previously treated cases was 58.5%, 60.2%, 62.7%, 61.7% and 71.3% in 2001, 2002, 2003, 2004 and 2005, respectively. A significant increasing trend could be discerned for MDR-TB among both new and previously treated cases (p<0.001, p=0.002 for trend, respectively). The proportion of XDR-TB among new cases was 0%, 2.3%, 3.1%, 2.5% and 6.3% in 2001, 2002, 2003, 2004 and 2005, respectively, and the proportion of XDR-TB among previously treated cases was 9.1%, 15.7%, 17.3%, 19.9% and 19.1% in 2001, 2002, 2003, 2004 and 2005, respectively. A significant increasing trend could be discerned for XDR-TB among both new and previously treated cases (p=0.005, p<0.001 for trend, respectively). CONCLUSION: Both MDR-B and XDR-TB were gradually increased among both new and previously treated cases. Integrated national surveillance, including the public and private sectors, will be needed to estimate the exact status of antituberculous drug resistance.

BACKGROUND: Few studies on how to diagnose pulmonary neuroendocrine tumors through morphometric analysis have been reported. In this study, we measured and analyzed the characteristic parameters of pulmonary neuroendocrine tumors using an image analyzer to aid in diagnosis. METHODS: Sixteen cases of typical carcinoid tumor, 5 cases of atypical carcinoid tumor, 15 cases of small cell carcinoma, and 51 cases of large cell neuroendocrine carcinoma were analyzed. Using an image analyzer, we measured the nuclear area, perimeter, and the major and minor axes. RESULTS: The mean nuclear area was 0.318+/-0.101 microm2 in typical carcinoid tumors, 0.326+/-0.119 microm2 in atypical carcinoid tumors, 0.314+/-0.107 microm2 in small cell carcinomas, and 0.446+/-0.145 microm2 in large cell neuroendocrine carcinomas. The mean nuclear circumference was 2.268+/-0.600 microm in typical carcinoid tumors, 2.408+/-0.680 microm in atypical carcinoid tumors, 2.158+/-0.438 microm in small cell carcinomas, and 3.247+/-1.276 microm in large cell neuroendocrine carcinomas. All parameters were useful in distinguishing large cell neuroendocrine carcinoma from other tumors (p=0.001) and in particular, nuclear circumference was the most effective (p=0.001). CONCLUSIONS: Pulmonary neuroendocrine tumors showed nuclear morphology differences by subtype. Therefore, evaluation of quantitative nuclear parameters improves the accuracy and reliability of diagnosis.

PURPOSE: The purpose of this study was to analyze the research papers published in three nursing journals to suggest the direction for Journal of Korean Oncology Nursing (JKON). METHODS: To compare JKON with Journal of Korean Academic Society of Nursing Education and Cancer Nursing, all the research papers published in those three journals, 2010 were reviewed using an analysis criteria developed by the researchers, focusing on type of research, characteristics of authors and subjects, research design, data collection and analysis methods, sample size estimation, and ethical considerations regarding data collection. RESULTS: JKON lacked research papers which were supported by research funds, produced by multidisciplinary teams, addressing cancer survivors or patients with metastatic cancers, and written in qualitative methodologies. However, JKON showed higher ratio of research papers than the other two journals which were adapted from thesis or dissertations, describing sample size estimation process precisely, and participating subjects diagnosed with various cancers. CONCLUSION: The study found out that JKON is presenting well the area of oncology nursing in Korea and also has several weak points that need to be improved. The study therefore suggested several recommendations for the JKON to take the professional and global leader roles.

We report a rare case of hilar squamous cell carcinoma. A 62-year-old Korean woman complaining of nausea was referred to our hospital. Her biliary computed tomography revealed a 28 mm-sized protruding solid mass in the proximal common bile duct. The patient underwent left hemihepatectomy with S1 segmentectomy and segmental excision of the common bile duct. Microscopically, the tumor was a moderately differentiated squamous cell carcinoma of the extrahepatic bile duct, without any component of adenocarcinoma or metaplastic portion in the biliary epithelium. Immunohistochemically, the tumor was positive for cytokeratin (CK) 5/6, CK19, p40, and p63. Squamous cell carcinoma of the extrahepatic bile duct is rare. To date, only 24 cases of biliary squamous cell carcinomas have been reported. Here, we provide a clinicopathologic review of previously reported extrahepatic bile duct squamous cell carcinomas.

A 51-year-old woman presented with severe dizziness. The brain magnetic resonance image revealed a 5.5 cm multiloculated mass with a thick rim in the left temporal lobe. Cytological examination of frozen diagnosis of the mass showed hypercellular sheets of round and rhabdoid cells in a hemorrhagic background, and two mitotic figures were observed. Histologically, the excised dura-based mass consisted of predominantly round cells with small foci of rhabdoid tumor cells in a pseudoalveolar pattern in a hemorrhagic background, and the cells showed nuclear positivity for signal transducer and activator of transcription 6 as well as frequent mitosis. The mass was diagnosed as a grade 3 solitary fibrous tumor (SFT)/hemangiopericytoma (HPC). The cytological diagnosis of SFT/HPC is challenging because of the heterogeneous cytological findings, such as histological heterogeneity, and because there are no standardized cytological criteria for malignant SFT/HPC. Cytological findings, such as singly scattered small cells, hypercellularity, rare ropy collagen, and round and rhabdoid cells with pseudoalveolar pattern, may assist in the diagnosis of malignant SFT/HPC.

Necrobiotic xanthogranulomatous reaction is a multiorgan, non-Langerhans cell histiocytosis with an unknown etiology. Occurrence in the salivary gland is extremely rare. We recently identified a case of necrobiotic xanthogranulomatous sialadenitis in a 73-year-old Korean woman who presented with a painless palpable lesion in the chin. There was no accompanying cutaneous lesion. Partial resection and subsequent wide excision with neck dissection were performed. Pathological examination showed a severe inflammatory lesion that included foamy macrophages centrally admixed with neutrophils, eosinophils, lymphocytes, plasma cells, and scattered giant cells, as well as necrobiosis. During the 12-month postoperative period, no grossly remarkable change in size was noted. Necrobiotic xanthogranulomatous inflammation may be preceded by or combined with hematologic malignancy. Although rare, clinicians and radiologists should be aware that an adhesive necrobiotic xanthogranuloma in the salivary gland may present with a mass-like lesion. Further evaluation for hematologic disease and close follow-up are needed when a pathologic diagnosis is made.
