The diagnosis of ovarian tumor has been mainly dependent on manual pelvic examination and ultrasonography. Butin case of malignant ovarian tumor, CT has more advantages over ultrasonography in assessing anatomic details,relationships to bowel loops, precise extents of tumors and follow-up examinations after surgery. Authors analyzedCT features of 46 cases of patholgocially proven ovarian tumors for recent 4 years at keimyung University DongsanHospital. The results were as follows: 1. The msot common tumor was serous cystadenocarcinoma(9 cases:20%),followed by metastases(8 cases: 17%), mucinous cystadenocarcinoma(7 ases:15%), mucinous cystadenocarcinoma(5cases:11%), teratoma(5 cases:11%), lymphoma(3 cases: 7%) and dysgerminoma(2 cases:4%). 2. The ovarian tumors werevariable in size from 2.5cm to 33cm in diameter. Most of the solid tumors were smaller than 10cm in diameter andmost of the cystic tumors were larger than 10cm in diameter. Usually mucinous tumors were much larger than seroustumors. Mucinous cystadenomas were the largest tumors. 3. Unilateral tumors(left 19,right 13 cases) were morecommon than bilateral tumors(12 cases). Bilateral tumors were seen in serous and mucinous cystadenocarcinoma,metastases and lymphoma. 4. CT features of mucinous cystadenomas were smooth margins and thin wall of the tumormasses and multiloculated cysts with internal septa in all 7 cases. 5. In contrast, CT demonstration ofbilaterality, irregular margin, thick wall, enhancing solid lesions, septal irregularity, adhesion to adjacentstructures, peritoneal/omental implantation, ascites and hydronephrosis were signs suggesting malignancy. CTfeaturs of the serous cystadenocarcinoma were mostly solid to mixed nature(83%), irregular margin(75%), enhancingsolid lesion(67%), papillary growth (75%), internal septa(58%), multilocularity (58%) and calcification (25%) indescending order of frequency. 6. On CT, mucinous cystadenocarcinoma were irregular-marginated, thick-walled,cystic tumors with enhancing solid lesion, septal irregularity and signs of metastasis, although there were somecases having similar features of benign. 7. Among the extrapelvic CT findings of malignant epithelial ovariantumor, peritoneal/omental implants(11 cases:79%) and ascites(10 cases:71%) were the most common, and indistinctuterus(6 cases:43%), bowel adehsion(5 cases:36%) and pseudomyxoma peritonei (2 cases) were descending order offrequency. 8. CT features of teratoma were diagnostic having at least three more of different tissue densitiesamong fat, water, soft tissue and calcific densities. Also there were thick wall (4 cases) and fat-fluid level(1case). 9. In 8 cases of ovarian metastases, there were solid type tumor smaller than 10cm in 4 cases and hugecystic in 2 cases. The site of primary cancer were stomach in 4 cases, colon , cervix, endometrium and unknown ineach one case. 10. In 3 cases of malignant lymphoma, the CT featurs were solid in appearance, smaller than 10cmand accompanied by lymphadenopathy in all cases.

Non-typhoidal Salmonella infections, which rarely present with multiple complications, are predominantly seen in immunocompromised patients. In particular, non-typhoidal Salmonella infections presenting with more than two complications are extremely rare. Here, we report a case of an infected pseudoaneurysm in the aortic arch caused by a non-typhoidal Salmonella species complicated by pleural empyema, pericarditis, pericardial empyema, and mediastinitis. To our knowledge, this is the first such case report in Korea.

Melioidosis is a life-threatening disease caused by Burkholderia pseudomallei , which is endemic in Southeast Asia and Northern Australia. It may manifest as a pulmonary lesion, osteomyelitis, septicemia, or abscesses of soft tissue or various organs. However, soft tissue abscess associated with bacteremia, especially those found in the head and neck, are rarely reported. We report a case of disseminated septicemia due to Burkholderia pseudomallei presenting as head and neck abscesses in a 55-year-old Korean man with a history of working in Malaysia. This is the first report of fatal melioidosis presenting as a complicated skin and soft tissue infection, in Korea.

The successful treatment of community-acquired pneumonia requires appropriate, empirical antimicrobial therapy. The etiology and antimicrobial susceptibility of major pneumonia pathogens can differ by country. Therefore, the ideal treatment guidelines for community-acquired pneumonia should be based on the studies performed in each country. We developed a treatment guideline for community-acquired pneumonia for immunocompetent adults in Korea. This guideline was developed by the joint committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory diseases.

PURPOSE: To investigate the differences in clinical features and laboratory findings between group D and non-group D non-typhoidal Salmonella (NTS) gastroenteritis in children. METHODS: A retrospective chart review of children diagnosed with NTS confirmed by culture study was performed. The clinical features and laboratory findings of group D and non-group D NTS were compared. RESULTS: From 2003 to 2012, 75 cases were diagnosed as NTS at our center. The number of group D and non-group D patients was 45 and 30, respectively. The mean age was higher in group D than in non-group D patients (5.1 years vs. 3.4 years, p=0.038). Headaches were more frequently observed (p=0.046) and hematochezia was less frequently observed (p=0.017) in group D than in non-group D NTS gastroenteritis patients. A positive Widal test result was observed in 53.3% of group D and 6.7% of non-group D NTS cases (O-titer, p=0.030; H-titer, p=0.039). There were no differences in white blood cell counts, level of C-reactive protein and rate of antimicrobial resistance between group D and non-group D cases. CONCLUSION: The more severe clinical features such as headache, fever, and higher Widal titers were found to be indicative of group D NTS gastroenteritis. Additionally, group D NTS gastroenteritis was more commonly found in older patients. Therefore, old age, fever, headache, and a positive Widal test are more indicative of group D NTS than non-group D NTS gastroenteritis. Pathophysiological mechanisms may differ across serologic groups.
