In order to evaluate the ability of spin-echo MR imaging to differentiate slow flow from mural thrombus in aortic diseases, we reviewed the spin-echo MR images of 13 patients with intraaortic thrombus documented by CT (N=11) or aortography (N=2). Six patients had aortic aneurysms and seven had aortic dissection. Intraaortic mural thrombi were accompanied by flow-related intraluminal signal of various patterns and extents in all 13 patients. On 10 gated MR studies, slow flow regions showed even-echo rephasing phenomenon (N=8), interslice variation of signal intensities of the intraluminal signal (N=7) and flow-related ghost artifact (N=2). However, these MR flow phenomena were obscured on two of three non-gated studies. Seven of 13 intraaortic thrombi remained hyperintense on T2-weighted second-echo images. In these circumstances, a hypointense boundary layer between slow flow and mural thrombus, which was caused by either 'boundary layer dephasing phenomenon' of slow flow or 'paramagnetic T2 shortening' of fresh clot at the edge of mural thrombus, was useful in discriminating the area of slow flow from that of mural thrombus. Proper interpretation of spin-echo MR images may obviate the need for phase display imaging or gradientecho imaging in differentiating slow flow and mural thrombus.

We experienced the 17 hands of 11 patients with Dupuytren disease, which was known as relatively rare in orientals. Retrospectively, we analyse it and the results were followings; l. Among 11 patients, 10 patients were male and average age was 62.5 years (49 to 77 years) 2. Most (15 hands, 88%) of patients had symptoms of flexion contracture, nodule and contracted cord, simultaneously. 3. Occupation of patients was agricultural laborer in 9 patients (82%). 4. In 9 patients(82%); individual habit of alcoholic drinking, more than 3 times per week, and smoking, 1 package per day, over 20 years more, was observed. 5. In 15 hands (88%), ulnar side of fingers (4th+5th, 5th only or 3rd+4th+5th)was involved. 6. Surgical treatment was performed in 9 hands of 7 patients, with results of excellent in 6 hands (67%) and no recurrence, in average follow up 2.6 years (1.5 year to 3.7 year)

Respiratory syncytial virus (RSV) and Influenza virus are the most common pathogen for causing severe upper respiratory infection in all age groups. A multiplex reverse transcription polymerase chain reaction (RT-PCR) has been developed to detect and subtype influenza A (H3N2 and H1N1), B virus and RSV simultaneously in one tube reaction. Amplification with primers derived from conserved sequences within the nucleocapsid for RSV and hemagglutinin subunit for Influenza A (H3N2 and H1N1) and B viruses yielded a 384 bp, a 300 bp, a 236 bp and a 151 bp, respectively. Assay specificity was confirmed by pulse field gel electrophoresis and autosequencing method. Assay sensitivity was 3 PFU/ml of RSV, 22 PFU/ml, 45 PFU/ml of Influenza type A (H3N2 and H1N1) and 6.6 PFU/ml of Influenza B virus by plaque assay. A rapid and sensitive detection method of a one-tube with multiplex RT-PCR capable of identifying more than one viral template as well as synchronizing reverse transcription and PCR had the potential to produce considerable savings of time and cost effectiveness in the diagnostic laboratory.

PURPOSE: MRI is known to be an effective imaging modality of the aorta and its role is steadily increasing in the evaluation of acquired aortic diseases including aortic dissections and aortic aneurysms. However, differentiation of the aortic dissections with thrombosed false lumen from the aortic aneurysm with mural thrombus in MRI has not been easy. Therefore, the authors tried to find the characteristic MR featrses which would to differentiate the two diseases. MATERIALS AND METHODS: MR images of 6 patients with thrombosed aortic dissection and 7 patients with thrombosed aortic aneurysms were reviewed retrospectively and compared in regand to shape and extent of thrombus, dimension of aorta, and luminal flow signal. RESULTS: Thrombosed aortic dissections showed sharply demarcated crescent shaped aortic wall thickening of even thickness involving long segment of the aorta, whereas thrombosed aortic aneurysms showed irregular aortic wall thickening of uneven thickness localized in the short dilated segment of the aorta. Characteristically aortic aneurysm with mural thrombus showed eccentric intraluminal slow flow signal. In contrast to the signal void of the true lumen in aortic dissections, the residual lumen of the aortic aneurysm with mural thrombus revealed intraluminal signal due to slow flow. CONCLUSION: Familiarity to these MRI findings of thrombosed aortic dissections and aortic aneurysms may lead to the accurate differential diagnosis in majority of cases.

We have recently experienced a case of cysticercosis treated with praziquantel. The patient, 22-year-old female, with 43 cystic masses had marked clinical response to the administration of praziquantel (75 mg/kg/day) for 7 days. It seems that praziquantel, anticestodal agent, might be a safe and effective therapy for this infection.

Malignant degeneration of mature cystic teratoma has been reported in 1~3% of cases, usually between the age of 30 and 70 years with a peak incidence of 40~60 years. The most common malignancy developing in such tumors is squamous cell carcinoma arising in a mature cystic teratoma. Hirakawa reported two patients with benign teratomas diagnosed 25 and 32 years prior to surgery for malignancy and Dorothea reported a patient who was diagnosed as benign teratoma 50 years prior to operate for carcinoma. But there has been no report of squamous cell carcinoma arising in the mature cystic teratoma with direct invasion to gastrointestinal tract. We report a case of squamous cell carcinoma with direct invasion to transverse colon and jejunum in 62-year-old female who was diagnosed as mature cystic teratoma 20 years ago.

A 19-year-old man had a good neurologic recovery from a severe hypothermia(19 degrees C) and a prolonged coma following active infernal rewarming. From inhaling hydrocarbons, he was left unconscious on the cold floor for 24 hours. As soon as the patient was brought into the emergency medical center, he was early evaluated arid treated aggressively. ECG showed Osborn(J) wave on all leads. The temperature o( patient was increased by 2-3 degrees C per hour through active external rewarming (by heating blankets and warm bag) and active infernal rewarming (by airway rewarming, warmed IV fluids, gastrointestinal tract irrigation, and bladder irrigation). The temperature reached 36 degrees C after 6 hours. Active infernal rewarming provides rapid core rewarming with the additional benefit of circulatory support during the period of cardiac instability.
