Choriocarcinoma associated with a normal pregnancy is rare. Futhermore, choriocarcinoma coexistent with a viable pregnancy is even rarer and associated with a greater risk of hepatic and cerebral involvement. So timely diagnosis of the disease is important for successful treatment and aggressive diagnostic procedures may therefore warranted. The patient should be treated with primary intensive combination chemotherapy(EMA-CO) and the selective use of irradiation and surgical therapy. We experienced a case of metastatic choriocarcinoma of lung and kidney following preterm delivery at 34th week of pregnancy and so present it with brief review of literature.

BACKGROUND: Motorcycles are one of the important members of commercial transportation because of the convenient use during congested traffic conditions and the ease of parking in narrow streets. This study investigates the characteristics of crashes and traffic signal violations caused by motorcycle couriers. METHODS: From the national compensation data, this study analyzed the traffic crashes caused by 671 motorcycle couriers. RESULTS: Among 671 injured couriers, 50.6% were aged less than 40 years, 49.2% run in a small business of < 5 employees, and 47.2% had work experience of < 6 months. Motorcycle crashes occurred mainly due to “rider overturned alone” (67.5%), in the daytime (73.5%), or on cloudy or clear days (77.2%). However, the violation rate caused by motorcycle couriers was high in couriers in a small business of < 5 employees (13.9%), with work experience of < 6 months (13.9%), on cloudy or clear days (12.4%), on an intersection (29.8%), in the type of “crash with a vehicle” (31.2%), or in a death accident (35.7%). CONCLUSION: The findings of this study can be used as a baseline in devising policies for preventing crashes of motorcycle couriers.

Hepatie hilar ductal carcinoma is relatively rare, but the prognosis is known to be poor because an early diagnosis is difficult. Because the majority of patients are already infiltrated into adjacent organ by itself at the diagnosis, the rate of resectability is low. The best method of treatment is curative resection, and the range of tumor invasion is very important. The preoperative diagnosis is difficult because the cholangiography may be normal in cases of superficial invasion. Multifocal lesions within the biliary tract may be identified in as many as 10 percent of patients, Especially, the papillary type has the best prognosis and is associated with multiple tumors within the bile duct. We report a case that percutaneous transhepatic cholangiogram showed normal distal common bile duct, but the hepatic hilar confluence and ampulla of Vater lesion was confirmed as adenocarcinoma.

OBJECTIVE: Evaluation of how much the presence of dementia is underdiagnosed or misdiagnosed in the elderly population by themselves. METHOD: The number of self-professed dementia cases was compared to the estimated number of cases with cognitive impairment based on the Korean version of the Mini-Mental State Examination (MMSEK) employed in a nationwide survey "Need assessment of the long-term care in the elderly" in three representative areas of Korea. The would-be dementia cases were analyzed. RESULTS: Only eighteen (0.7%) of 2,638 reported the presence of dementia while 414 (15.7%) were diagnosed as having questionable cognitive impairment and 385 (14.6%) as having definite cognitive impairment on the MMSEK. On the other hand, some of the self-professed "dementia" cases were not impaired on the MMSEK. CONCLUSION: The public should be educated on clinical manifestations of dementia for its early diagnosis and appropriate treatment because they are mostly without understanding about dementia.

The development of renal glomerular lesions secondary to severe visceral infection (pulmonary, pleural, retroperitoneal or hepatic abscess) is not generally appreciated. Such patients resemble those with infective endocarditis. The suggested pathogenetic mechanisms by which infection can cause glomerular damage are immunologic interaction, direct toxicity of a bacterial products, and some other triggering factors; However, direct correlation between the infectious and immunologic events has not been demonstrated. The histopathologic findings of infectious glomerulonephritis are variable, and these findings, as well as the clinical abnormalities, may resolve with effective antimicrobial therapy or abscess drainage. We experienced a case of glomerulonephritis and acute renal failure due to staphylococcal retroperitoneal abscess. The patient was a 58-year-old man who presented with abdominal and back pain. We performed an abdominal CT scan which showed a retroperitoneal abscess which was proven to be a staphylococcal infection upon percutaneous abscess drainage. Furthermore, we performed a renal biopsy in order to investigate hematuria, RBC casts, and proteinuria. Pathologic findings revealed postinfectious glomerulonephritis. Abscess drainage and sensitive antibiotics were administered, after which his symptoms and urinary abnormalities disappeared, and the retroperitoneal abscess subsided. Here, we report a case of a staphylococcal retroperitoneal abscess which led to postinfectious glomerulonephritis and acute renal failure along with a brief review of the literatures.

Echinococcus granulosus, an intestinal tapeworm of dogs and other canids, infects humans in its larval stage and causes human echinococcosis or hydatid disease. In the Republic of Korea, 31 parasite-proven human echinococcosis cases have been reported, most of which were imported from the Middle East. We recently examined a 61-year-old Korean man who had a large cystic mass in his liver. ELISA was negative for tissue parasitic infections, including echinococcosis, cysticercosis, paragonimiasis, and sparganosis. The patient underwent surgery to remove the cyst, and the resected cyst was processed histopathologically for microscopic examinations. In sectioned cyst tissue, necrotizing protoscolices with disintegrated hooklets of E. granulosus were found. In some areas, only freed, fragmented hooklets were detected. The patient had traveled to western and central Europe in 1996, and had no other history of overseas travel. We report our patient as a hepatic echinococcosis case which was probably imported from Europe.
