ABSTRACT
For diagnosis of prostate cancer, MRI was performed in 91 patients prior to prostate biopsy, and prostate cancer was detected in 37 patients. The ability of MRI diagnosis compared with biopsy was accuracy 0.84, sensitivity 0.95, and specificity 0.76.In 26 patients (14 patients with prostate cancer) from whom MR images were obtained by diffusion weighted imaging, ADC value and PSA value showed a reverse correlation significantly.The ADC value was 0.97±0.23-3mm2/sec in the cancer area, 1.51±0.20-3mm2/sec in the normal peripheral zone, and 1.47±0.12-3mm2/sec in the normal central zone. The ADC value in the cancer area was smaller than that in the normal peripheral area or in the normal central zone significantly (p<0.001).The relation between ADC value and Gleason score did not show any correlation. However, when the Gleason score was under 6, ADC value was 1.11±0.20-3mm2/sec, and when it was over 7, ADC value was 0.81±0.19-3mm2/sec which showed a lower value than the ADC value with Gleason score under 6 significantly (p<0.05).MRI was effective for visualization of prostate cancer. We concluded that pre-biopsy MRI in prostate cancer would allow not only systemic-biopsy but also accurate targeting-biopsy, and it would improve the diagnosric ability of biopsy.

A 46-year-old female patient with non-alcoholic steatohepatitis (NASH) was administered nateglinide, an insulin secretagogue, for 7 months, and then polyenephosphatidylcholine, an anti-oxidant medication, in accordance with the two-step hypothesis of NASH, with insulin resistance as the initial pathogenesis and oxidative stress as the second. HOMA-R, an index of insulin resistance, improved, and hepatic marker levels improved markedly by four weeks after initiation of polyenephosphatidylcholine. The beneficial effects of treatment continued over the 24 months of the study. A liver biopsy evaluated using Brunt's criteria showed improvement from stage 2 to stage 0 after 9 months. These findings suggest the therapeutic efficacy of step by step treatment of NASH in accordance with the two-stage hypothesis.
ABSTRACT
A survey was carried out on how the To-no District is coping with the need of first aid for patients requiring life-supporting treatment before hospitalization. Although there were cities in this district where statistics on first aid were not available, the survey found that, during the 4-year period from 1994 through 1997, bystander CPR (cardiopulmonary resuscitation) saved 11.2% of the lives of patients with CPA (cardiopulmonary arrest). Incidentally, 11.3% of the population attended CPR courses offered by public institutions. Gifu Prefecture has helicopters for use in rescue work, but the survey found that some cities had not ever sponsored drills using helicopters in life-saving operations. Our findings revealed the indifference of the general public as well as administrators in this district toward emergency care. Public recognition of the importance of the care of suddenly ill or injured patients must be gained. Furthermore, acquisition of skills required for first aid by lay people and technical improvement of these skills in professional rescuers are necessary. The authors think that these are the community educational responsibility of hospitals and other medical institutions.
ABSTRACT
A 73-year-old man visited our hospital with complaints of fever, epigastric painand jaundice. Laboratory examinations showed elevation of GOT, GPT, ALP, LAP and amylase. Abdominal ultrasonography revealed gall bladder stones. Endoscopic findings showed parapapillary diverticulum, but the common bile duct stone was not revealed by endoscopic retrograde cholangiography. He was conservatively treated and then discharged. Two months after, the patient was readmitted for cholecystitis and underwent cholecystectomy. After further 2 months, he was again admitted for the same symptoms as those on first admission. We diagnosed this case as Lemmel's syndrome and performed emergency endoscopy. Endoscopic findings revealed the meal rest inside the parapapillary diverticulum. After we removed the meal rest obstructing the orifice of the papilla of Vater using grasping forceps, we performed EST. Purulent bile gushed out from the orifice. Two years have elapsed since them. Cholangitis has not recurred during this period. Therefore, we concluded that EST is effective in treating Lemmel's syndrome.
