Percutaneous needle aspiration biopsy (PNAB) of suspected pulmonary malignancy is a simple, safe and practicalmethod, so should be used earlier and moe frequently to shorten the diagnostic interval. In Korea Cancer CenterHospital, 64 patients underwent PNAB with a diagnotic yield of 87.5%. 7 patients and a pneumothorax and in 3patients developed transient hemoptysis. Of 58 malignant of no

Choriocarcinoma is a relatively rare malignancy of which characteristic is rapid metastasis to the other organs. It is related to the previous gestation or originated from the teratoma. Choriocarcinoma is mostly originated from the intrauterine chorionic villi, but it is rarely originated from the utreine cervix, fallopian tube, ovary, vagina and pelvic cavity. Primary choriocarcinoma of the fallopian tube is exceedingly rare and it is originated from ectopic tubal pregnancy, tubal migration from the intrauterine pregnancy or intratubal teratoma. 9 Symptoms and signs of the choriocarcinoma originated from the ectopic pregnancy are abdominal pain, vaginal bleeding, palpable adnexal mass, positive pregnancy test and amenorrhea. Thus it is difficult to distinguish choriocarcinoma from ectopic pregnancy on the basis of symptoms before the microscopic diagnosis presented.20 Effective treatment of choriocarcinoma is chemotherapy. Additional operation is possible. B-HCG is a useful measure for the follow up. We experienced a 36-year-old multigravida Korean woman who was diagnosed as the rupture of ectopic pregnancy after left salpingectomy in our hospital and then confirmed primary choriocarcinoma of the fallopian tube without metastasis on microscopic finding. Postoperative chemotherapy was performed with methotrexate. The follow up of disease is still on going at two month intervals and she has remained healthy, We report this case with review of literatures.

Two cases of CD30 positive ALCL is presented. A 27 year-old male patient presented with general lymphadenopathies, hepatosplenomegaly, splenic infarction, acute hepatitis, and hemopagocytic syndrome. The other 66 year-old female patient presented with general lymphadenopathies. Biopsy of the lymph node revealed proliferation of anaplastic pleomorphic tumor cells in the sinusoidal pattern. Immunohistochemical study revealed tumor cells were positive for LCA, T cell, and CD 30. All two cases were stage IIIA. Young patient was treat with 8 cycles of ProMACE-CytaBOM chemotherapy, and elderly patient was treated with 8 cycles of CHOP chemotherapy that resulted in complete remission with favorable clinical course.

PURPOSE: We designed the aft-multiple-slit (AMS) system to reduce scatter in cone-beam computed tomography (CBCT). As a preliminary study, we performed a Monte Carlo N-Particle Transport Code (MCNP) simulation to verify the effectiveness of this system. MATERIALS AND METHODS: The MCNPX code was used to build the AMS geometry. An AMS is an equi-angled arc to consider beam divergence. The scatter-reduced projection images were compared with the primary images only and the primary plus scatter radiation images with and without AMS to evaluate the effectiveness of scatter reduction. To obtain the full 2 dimensional (2D) projection image, the whole AMS system was moved to obtain closed septa of the AMS after the first image acquisition. RESULTS: The primary radiation with and without AMS is identical to all the slit widths, but the profiles of the primary plus scattered radiation varied according to the slit widths in the 2D projection image. The average scatter reduction factors were 29%, 15%, 9%, and 8% when the slit widths were 5 mm, 10 mm, 15 mm, and 20 mm, respectively. CONCLUSION: We have evaluated the scatter reduction effect of the AMS in CBCT imaging using the Monte Carlo (MC) simulations. A preliminary study based on the MCNP simulations showed a mount of scatter reduction with the proposed system.

OBJECTIVES: To examine the sex-specific factors associated with being unaware of one's hepatitis B virus surface antigen (HBsAg) seropositivity status in a large, HBsAg-positive population of Koreans. METHODS: In total, 1197 subjects aged 19 years or older who were HBsAg-positive according to data from the 2007-2012 Korea National Health and Nutrition Examination Survey were included. Subjects were considered unaware of their HBsAg seropositivity status if they answered that they had no knowledge of being previously infected by the hepatitis B virus (HBV) or diagnosed with HBV hepatitis. Multivariate Poisson regression models with robust variance estimate were used to assess the significance of the variables using weighted frequencies. RESULTS: The majority (77.8%) of HbsAg-positive Korean adults (females, 81.9%; males, 74.6%) were unaware of their HBsAg seropositivity status. We found that sex (female: prevalence ratio [PR] 1.19), household income (low: PR, 1.15), marital status (never married: PR, 1.18), self-rated health (moderate: PR, 1.14; good: PR, 1.12), and alcohol use (at least 2-3 times/wk: PR, 1.21) were associated with being unaware. In females, age (50 to 59 years: PR, 1.29; > or =70 years: PR, 1.30), household income (low: PR, 1.37; middle-low: PR, 1.24), and marital status (never married: PR, 1.33) were associated with being unaware. In males, self-rated health (moderate: PR, 1.14; good: PR, 1.21) and alcohol use (at least 2-3 times/wk: PR, 1.21) were associated with being unaware. CONCLUSIONS: Factors related to the socioeconomic status of females and the health-related behaviors of males were found to be associated with being unaware of one's HBsAg seropositivity status.
