Pseudoaneurysm is uncommon but a life threatening complication of chronic pancreatitis. Angiography has been the standard definitive imaging modality in the diagnosis of pseudoaneurysm. However, over the past 5 years duplux US and Dynamic CT have been proven to be valuable. The authors report a case of gastroduodenal pseudoaneurysm in chronic pancreatitis, which could be diagnosed by duplux US and Dynamic CT. Furthermore this case proved to be a pseudocyst which converted into a pseudoaneurysm by vessel rupture.

Closed loop onstruction represent a surgical emergency, because this lesion leads to small boweel infarction, perforation, and peritonitis if not treated in time. We analyzed the CT and ultrasonographic findings of 4 patients prospectively and 2 patients retrospectively with surgically proven closed loop obstruction of the small boweel to evaluate the characteristic findings, the cause of the closed loop obstruction and predictive criteria for the viablity of the involved bowel loop. The characteristic CT and sonographic features of the closed loop obstruction of the small bowel included; dilated fluid-filled bowel loops, the thickened bowel wall, absence of peristalsis, and ascites. In one case, closed loop obstructio originating from umbilical hernia was documented by CT and sonography. The possible criteria for the gangrenous changes could be the maximal thickness of bowel more than 7mm, and infiltration in the mesentery/omentum.

OBJECTIVES: Tourette's Disorder (TD) is a chronic neuropsychiatric disorder characterized by multiple motor and vocal tics with onset in childhood. The aim of this study was to ascertain the increased cortical information transmission in frontal area during tic suppression in drug naive boys with TD using new nonlinear analysis of EEGs, be called Transfer Entropy (TE) which can detect the directed exchange of information between two systems. METHODS: Subjects were 11 drug naive boys with DSM-IV diagnosis of TD and 10 control boys. Clinical assessments were performed, and EEGs were recorded from 19 scalp loci of the international 10-20 systems. TE was estimated by EEG timeseries data after noise reduction. TE difference between TD and control during resting state and between tic suppression and resting state in TD were investigated. RESULTS: Elevated TE was found in extensive channels, including frontal, central and temporal channels (F7, Fz, F8,Cz, C3, P3, T3, and T4) in resting state of Tourette's disorder compared to normal controls. During tic suppression elevated TE was found in more extensive and asymmetrical channels especially prefrontal area (Fp1, Fp2, F3, Fz, F7, F8, Cz, C4, C5, T3, and T4). CONCLUSION: These findings suggest that pathogenesis of Tourette's disorder involve impaired cortical neuronal modulation in subcortical neural circuits. EEG analysis of TE may be a useful tool to investigation of cortical mechanism of psychiatric illness.

Nineteen astrocytic neoplasms, such as 9 cases of glioblastoma multiforme, 6 cases of anaplastic astrocytoma and 4 cases of low grade astrocytoma, were analysed in view of the relationship between histopathologic grade, nuclear pleomorphism, grade of mutant p53 gene expression and mean survival time after operation. The histopathologic classification by Ringertz and immunohistochemical stain for mutant p53 gene with the DO-7 anti-p53 oncoprotein mouse monoclonal antibody were applied, and the results obtained were as follows; 1) Among 19 cases, 18 cases were located in the supratentorium, where 13 cases(42%) were located in the left and 17 cases(55%) in the right. 2) The p53 gene expression was detected in 12(63.2%) of the cases, as revealed by positive nuclear staining. All cases of glioblastoma multiforme showed p53 gene expression, compared with two(33.3%) cases of anaplastic astrocytoma and one(25%) case of low grade astrocytoma. The frequency and degree of histopathologic grade(p=0.03). 3) The mean survival time after operation was 29.49+/-4.08 months in cases with p53-negative tumors and 12.93+/-3.14 months in cases with p53-positive tumors(p<0.05). 4) Both histopathological classification and p53 gene expression showed a significant influence on servival(p=0.02 and p=0.03, respectively). 5) The relative risk for survival time was the highest in p53 gene expression. In conclusion, p53 gene expression appears to be one of the recommendable prognosticators among astrocytic neoplasms.

PURPOSE: To report the results of a combined anterior and posterior approach to complex acetabular fractures and establish the guidelines for the operative treatment of complex acetabular fractures. MATERIALS AND METHODS: Thirteen fractures (8 both column, 5 T-shaped fractures) of thirteen patients (8 men, 5 women) were treated with this combined anterior and posterior approach from August 1995 to December 1999. We reviewed the clinical and radiological results for an average of 33months (range, 12-60) follow-up. RESULTS: This approach resulted in an anatomical reduction in ten (78%) patients and, two imperfect and one poor reduction. The average Harris hip score was 69.2 (range, 58-87) and the clinical results were good in eleven, very good in one and poor in one patient using the D'Aubigne/Postel clinical grading. A poor reduction occurred in one patient who had a both column fracture that extended to the ipsilateral sacroiliac joint combined with a joint subluxation. CONCLUSION: Overall clinical results for most complex acetabular fractures treated by a combined anterior and posterior approach were preferable to other approaches, but we must consider an extensile or extended ilioinguinal approach to be an alternative surgical approach in this complicated fracture that involves the sacroiliac joint.

The purpose of this study was to describe the differences in three phenomenological research methods used to understand the experience of families of patients with cancer and so provide as guideline to novices first attempting qualitative research. The subjects were 3 family members - spouse, daughter, daughter-in-law -of cancer patients at S-hospital. Unstructured deep interviews were carried out and taped for further analyzed. Interviews were analyzed using three phenomenological methods ; Giorgi's, Colazzi's, and Van Kaam's. The results are as follows: The experience of family the analyzed using Giorgi's method showed different characteristics according to the family members' role. According to Colaizzi's method, they experienced burden, a willingness to care, role conflict, thanks to family and significant others, and ambivalence about treatment. Using Van Kaam's methodology, two categories were identified ; change of family function and burden. Themes in change of family function were positive attitude(9), role conflict(6), negative attitude(5), active attitude(2), and passive attitude(2) ; Themes in burden were emotional burden, physical burden, and economic burden. The result from using Giorgi's method were centered or individual characteristics and these results constituteds situational structured description and a general structured description. From Colaizzi's method the focus was on the common experience of all fo the subjects. In Van Kaam's method, subthemes (13), themes(8), and categories(2) were identified. So researchers should choose the qualitative method according to their research goals and methodological characteristics.

Condyloma acuminatum, commonly known as anogenital warts, is caused by human papillomavirus (HPV). The most common location of condyloma acuminatum in women is the vulva. Other locations are the vagina, anus and perianal area, perineum and cervix. Condyloma acuminatum most commonly occur due to receptive anal intercourse, and can enlarge to form exophytic masses on the perianal skin, but rarely involve the rectum. We experienced an occurrence of a 12 mm polypoid lesion in the rectum of a heterosexual woman detected during a colonoscopy. The polypoid lesion was excised and was diagnosed as condyloma acuminatum. The lesion was positive for HPV type 11 based on the use of an HPV DNA chip test.

In off-pump coronary artery bypass grafting (CABG), multiple proximal anastomosis may increase the risk of cerebral embolism (air, debris) and aortic injury (dissection, pseudoaneurysm). Radial artery (RA) has no intraluminal valve such as saphenous vein. We applied Cabrol technique using aortic root replacement for proximal anastomosis in off-pump CABG. Cabrol technique using RA graft can reduce numbers of proximal anastomosis and reduce number of aortic manipulation in off-pump CABG. We report a Cabrol technique for proximal anastomosis in off-pump CABG with RA graft.
