Pelvic fistulas may result from obstetric complications, inflammatory bowel disease, pelvic malignancy, pelvic radiation therapy, pelvic surgery, or other traumatic causes, and their symptoms may be distressing. In our experience, various types of pelvic fistulas are identified after pelvic disease or pelvic surgery. Because of its close proximity, the majority of such fistulas occur in the pelvic cavity and include the vesicovaginal, vesicouterine, vesicoenteric, ureterovaginal, ureteroenteric and enterovaginal type. The purpose of this article is to illustrate the spectrum of imaging features of pelvic fistulas.

Acoustic stimulation test(AST), is currently being used as an alternative tool of nonstress test (NST). However, there are no standard guideline for analysis of AST. Computerized numerical analysis of AST would be helpful for development of diagnostic criteria of AST. Fifty-one normal pre-term pregnancies entered to this study after conventional 20-minutes NST and 10-minutes AST. Acoustic stimulations were performed using Fetal Acoustic Stimulator (Model 146, Corometrics, US). We analyzed the FHR response after acoustic stimulation using our on-line computerized FHR analysis system, HYFM-I & II software. The changes of loss of signal, baseline FHR, variability, number of fetal movements, and number of FHR accelerations were analyzed numerically. The loss of signal was increased about 2 fold(122.61%). The baseline FHR was increased from 144.57bpm to 156.81bpm(8.5%) after acoustic stimulation. Number of fetal movements was increased about 2 fold(from 2.1 to 4.12/10 minutes). FHR variability was also increased from 17.81 bpm to 26.37 bpm. After AST, number of FHR accelaration was increased 55.47%(10sec 10bpm) and 68.42%(15sec 15bpm), respectively. In this study, we acrumulated elemental FHR data using computerized system after AST. These data would be helpful in the accurate analysis of AST and also enable us to develop the objective interpretation system for AST.

BACKGROUND: It has been documented that certain prognostic factors may affect the outcomes of the old aged victims by trauma. Considering that trauma is the sixth most common cause of death in people over the age of 65 years and there is a rapid growth of elderly population, it is paramount to understand the prognostic factors when dealing with geriatric trauma patients. Hypothesis and Goals : It can be hypothesized that the prognostic factors should be determined independently between populations being consisted of different races, countries, socio-economic states, cultures, or so on. Thus, study was designed to evaluate the factors affecting the outcomes of elderly Korean trauma patients. METHODS: One hundred forty six patients aged over 65 years were retrospectively reviewed, who visited the Emergency Canter of Korea University from January, 1997 to June, 1998. Of 146 patients, 7 were excluded due to discharge against advice or transfer to the other hospitals. Parameters analysed were age, sex, mechanism of injuries, body region injured, Injury Severity Score (ISS), previous medical illness, hospital morbidity, duration of hospital stay, and cost. Each patient was classified into improved or not-improved groups depending on the outcomes, and young-old or old-old group depending on the age. The factors affecting the hospital stay in improved patients were analyzed in the parameters of previous medical illness, hospital morbidity, multiple injuries, ISS, and age. All statistical tests were conducted with two-tailed levels of 0.05. RESULTS: Of 139 patients, the mean age was 74+/-7.1 years, mean ISS 9.3+/-7.26, mean hospital stay 27+/-27.1 days. Most commonly injured body region was the extremities due to fall from a level surface. Rate of previous illness showed 0.94 medical diseases per person and were aggravated after trauma in 39 patients (60.9%). Hospital morbidity rate was 0.46 incidents per person. There were no differences in age and duration of hospital stay between the improved and the not-improved group. Substantial differences were noted in affected body region, incidence of previous illness, and hospital morbidity between the groups (p=NS). Not-improved group had higher ISS (p<0.05). ISS, previous illness and hospital morbidity affected the duration of hospital stay in the improved group. Hospital stay was 40+/-25.1 days in patients with ISS over 6 while 6+/-8.6 days in those with ISS 5 (p<0.05). Hospital stay in the improved was 26+/-26.9 days while 31+/- 24.8 days in the improved old-old group (P=NS). Hospital stay in the young-old minor trauma (ISS5) patients with previous illness and hospital morbidity was 26+/-10.1 days while 4+/-7.3 days in those without previous illness and hospital morbidity (p<0.05). CONCLUSION: Previous medical illness and hospital morbidity, not age, are predictive of outcomes of geriatric trauma patients with respect to hospital stay. As most of the hospital morbidity was a trauma-induced aggravation of previous medical illness and hospital morbidity contributing poor outcomes can be potentially avoidable, routine aggressive care far the geriatric trauma patients with previous medical illnesses is needed.

Sustained downgaze mostly occurs in association with lesions affecting the dorsal midbrain. We report
sustained downgaze in a patient with hepatic encephalopathy. The sustained downgaze existed for
seven more days after she regained her consciousness. The persistent downgaze even after regaining
full consciousness indicates localized pretectal dysfunction rather than diffuse encephalopathy as the
mechanism of sustained downgaze in our patient. The ocular motor dysfunction in hepatic encephalopathy
may be due to localized dysfunction of the brainstem

BACKGROUND: Depressive symptoms are common in the medically ill patients although depressive disorders are considerably underdiagnosed and undertreated. Therefore, we examined the characteristics of depressive tendency in medical inpatients. METHODS: The patient group-144 subj.cts(90 males, 54 females) were selected from medical inpatients of Kae Jung hospital. 158 subjects(106 male, 52 females) with no prior history of diseases were selected for the control group. The Beck Depression Inventory(BDI) and Hamilton Rating Scale for Depression(HRSD) was used for both groups from June to December 1997. RESULTS: The patient group had a significant higher BDI and HRSD score than controls(p<0.01). In the patients, 31.3% had scores on the BDI greater than the cutting score of 21, and 26.4% had scores on the HRSD greater than the cutting score of 22. In the patients, demographic and medical variables were evaluated with respect to depression. those in their 60's, with education level of elementary school and below. the divorced, bereaved and separated, and having duration of illness more than one year were statistically more depressed, but depression was not associated with sex, religion and medical diagnosis. CONCLUSIONS: This study indicates that depressive tendency may be a common phenomena in medically ill patients. Therefore, we should suspect depression in the management of these patients.

The authors present the one case of a 22-year-old man admitted with intermittent quadriparesis and respiratory difficulty. On investigation, atlantoaxial instability and upper cervical cord compression due to abnormal soft tissue were revealed. We have performed transoral decompression and biopsy, and then posterior transarticular facet screw fixation with interspinous wiring and fusion. We could obtain immediate and long-term postoperative stability with Philadelphia collar only. The pathologic examination reveald connective soft tissue hypertrophy due to chronic mechanical irritation.

PURPOSE: To evaluate the diagnostic role of a three-dimensional MR cholangiopancreatography(MRCP) over endoscopic retrograde cholangio- pancreatography(ERCP) in various extrah-epatic biliary disease. MATERIALS AND METHODS: MRCP and ERCP were performed in 45 consecutive patients with suspected extrahepatic biliary diseases. MRCP was obtained using a reverse fast imaging with a steady-state free precession (reverse FISP : PSIF) sequences, and then images were reconstructed by standard MIP algorithm. The predictability of biliary dilatation and level of obstruction of MRCP was evaluated using ERCP as a gold standard. The accuracy distinguishing malignant from benign lesions, and overall diagnostic accuracy were compared between MRCP and ERCP. RESULTS: The sensitivity, specificity and accuracy of MRCP in predicting biliary dilatation were 94.6%, 75.0% and 91.1%, respectively. The level of obstruction was accurate in 87.0% with MRCP. The sensitivity, specificity and accuracy MRCP and ERCP in distinguishing malignant from benign lesions were 76.2%, 87.5% and 82.2% and 71.4%, 83.3% and 77.8%, respectively. The overall diagnostic accuracy was 60.0% with MRCP and 55.6% with ERCP. CONCLUSION: 3D MRCP shows a good diagnostic value compared to that of ERCP, and can replace a ERCP.

The encapsulated hepatocellular (HCC) is a pathologic subtype of HCC. It is a well defined tumor that tends to grow slowly, and has a better prognosis than any other gross forms of HCC. Twenty surgically resected HCC were evaluated retropectively to correlate the thickness of pseudocapsules in pathology with those in computed tomography and ultrasound. At a histologic examination, pseudocapsules of seven cases were composed of two layers, an inner compact fibrous zone and outer loose fibrous zone interlaced with compressed liver parenchyma containing small vessels and newly formed bile ducts. Sonographic thickness and pathologic measurements of pseudocapsule relatively well correlated, but the former slightly overestimated the thickness of pathologic pseudocapsule (r=0.825, y=2.56x-1.23, P<0.05). On the other hand, thickness in CT and pathologic measurement did not correlate well. Thirteen cases showed one layer of pseudocapsule in which two cases were composed of thin layer of compact fibrosis and eleven cases composed of loose fibrosis. There were poor correlations in this group between thickness of pseudocapsules in pathology and those in images. Image overtly overestimated the thickness of the pseudocapsules in pathology. In conclusion, radiologic pseudocapsule of HCC may represent the compressed liver parenchyma as well as the fibrous pseudocapsule.
