PURPOSE: To evaluate whether radial rigidity measured using RigiScan(R) represents the intracorporeal pressure effectively. MATERIALS AND METHODS: From January 1998 to May 1999, total of 23 patients with erectile dysfunction were evaluated by RigiScan(R) and duplex ultrasonography after the intracorporeal injection of prostaglandin E1. Peak systolic velocity and end diastolic velocity were measured by duplex ultrasonography and then the resistance index was calculated as (peak systolic velocity-end diastolic velocity)/(peak systolic velocity). Radial rigidity of penile tip and base was measured by RigiScanR . The results were analyzed statistically by PC-SPSS version 7.5. RESULTS: There were statistically significant correlations between radial rigidity of penile tip and base and the resistance index by Spearman's correlation analysis, respectively (r=0.680, p<0.001)(r=0.703, p<0.001). When radial rigidity of penile tip and base exceeded 60% of maximum, radial rigidity of penile tip and base again correlated well with the resistance index, respectively (r=0.659, p=0.020)(r=0.759, p=0.011). Based on clinically determined degree of erection, radial rigidity of penile tip and base represented the intracorporeal pressure effectively. CONCLUSIONS: Radial rigidity measured by RigiScan(R) represents the intracorporeal pressure effectively.

A study was made of 104cases of neonatal hyperbiliruinemia receiving blood exchange transfusion at Kwangju Christian Hospital from January 1969 to December 1975, with the following results: 1. 52 patients(50%) returned for follow-up, 9 patients(8.7%) had died, and 43 patients(41.3%) did not return. 2. Of the 52 patients returning, developmental status was studied by D.D.S.T. 43 patients(82.7%) had normal development, 8(15.4%) were retarded, and 1(1.9%) was questionable. No patients had a failing score. Most of the retarded patients had cerebral palsy, due to kernicterus. 3. There was no retardation among patients exchange-transfused at age of less than 5days, or over 8 days(except 1 pts.) , and with less than 30mg% of Pre-B.E.T. serum bilirubin level. 4. No significant difference of sex incidence was noted. 5. ABO incompatibility (57%) was predominant as the etiology and main cause of retarded development (19.4%), but the idiopathic type of hyperbilirubinemia(41.3%) was interestingly high among these B.E.T. patients. 6. Mean value and standard error of pre-B.E.T. serum bilirubin levels are as follows: Normal development group:30.80+/-1.60 Retarded development group:38.83+/-2.35 The difference of men values between both groups is very significant according to the t-test. 7. Motor disturbance was the predominant handicap in retarded patients at ages less than 3 years, and after this there was a tendency toward recovery, accompanied by mild speech disturbance. Hearing loss, especially of high pitched tone, was noted in 1 patient and confirmed by audiometry.

Almost always patients with multiple neurofibromatosis show cafe-au-lait macules on their skin. At times the skin macules are seen even before the appearance of the neurofibromata in childhood. The author experienced one case of neurofibromatosis in a 12-year-old boy who has no cafe-au-lait macules. Besides the clinical peculiarity of having no skin pigmentation, the histopathology of the case showed well-formed double-palisading structure, which is not common among the micro-scopical findings of neurofibromata.

Uterine torsion is defined as the mtation of more than 45 degrees around the long axis of the uterus or a rotation which is severe enough to produce symptoms. Torsion of the human pregnant uterus is a very rare complication. The diagnosis is problematic and is often made during a cesrean section due to inhibited labor. Torsion of the human pregnant uterus can be caused by myoma or other uterine abnormalities, ovarian cysts, adhesions, abnormal fetal presentations, or fetal abnormalities ( though no cause can be found in about 20% of cases ). Uterine torsion produces symptoms of varying severity depending on the degree of rotation, and duration of the pregnancy. High mortality rates for both mother and infant have been reported. We experienced one case of the torsion of term pregnant uterus and report this case with a brief review of the concerned literature.

Computerized tomography angiography (CTA) and magnetic resonance angiography (MRA) have been frequently used as non-invasive methods for the evaluation of cerebral vessels. The use of an invasive therapeutic method, transfemoral carotid angiography (TFCA), has also recently increased. The complication rate after TFCA is reported to be 0.9 % to 4%, and it is continuously decreasing. We experienced 2 patients who underwent TFCA as a diagnostic tool. The embolic type of cerebral infarction, which occurred within 30 hours, was diagnosed with performing diffusion weighted MRI (DW-MRI). One patient developed temporary dysphasia and motor weakness, but the patient improved after 2 days. The other patient presented with an altered mentality and motor weakness with some permanent deficits. TFCA is a less invasive method for treating cerebral vessels, and because this is a popular therapeutic modality, the frequency of complications will increase. Clinicians should bear in mind that complications may occur when performing TFCA and so they should be prepared to deal with them.

OBJECTIVE: Atypical teratoid/rhabdoid tumor(AT/RT) is a new entity among malignant pediatric brain tumors, and shows variable histopathologic features. The authors investigate the clinicopathologic and cytogenetic features of the tumor. METHODS: Five cases were included in this study ; three of them were primarily diagnosed, and two cases were reclassified from primitive neuroectodermal tumor/medulloblastoma to AT/RT. Mean age of patients at diagnosis was 5.6 years. The tumors were located in infratentorial or supratentorial areas. Maximum survival period was 13 months. RESULTS: Histopathologically, the tumors were mainly composed of modified rhabdoid cells and undifferentiated small cells, and mixed with epithelial, mesenchymal components, and other features mimicking glioma and chordoma. The histopathologic features were supported by polyphenotypic immunoreactivity, including epithelial membrane antigen, cytokeratin, vimentin, smooth muscle actin, and glial fibrillary acidic protein. Cytogenetic studies for karyotype analysis and fluorescent in situ hybridization revealed monosomy of chromosome 22 in two cases out of three cases of the tumor. CONCLUSION: Atypical teratoid/rhabdoid tumor may be an unique clinicopathologic entity, and histopathologic diagnosis should be made carefully by differentiating other polymorphous tumors of the brain.

OBJECTIVE: Despite improvement of therapeutic regimen, incidence of stroke increases and it remains a leading cause of death. Our study aims at offering variable data on recurrent strokes. METHODS: There were 59 patients who admitted from Jan. 2002 to Dec. 2004 due to recurrent strokes. A retrospective longitudinal cohort study was done. RESULTS: Four-hundred-seventy five patients, diagnosed with acute stroke, experienced 491 strokes in 3 years, and there were 75 recurrent strokes (15.3%) in 59 patients. These 59 patients were included in the study. First hemorrhagic cases (H) were 19 (32%), and the first infarction cases (I) were 40 (68%). Subsequent strokes after first stroke were as follows : H-->H 14 (23.7%)cases, H-->I 5 (8.5%), I-->H 8 (13.6%), I-->I 32 (54.2%). A Cox regression analyses showed that the first type of stroke was a significant factor to the second stroke as follows : if one has had a hemorrhagic stroke, the possibility of second hemorrhagic attack (H-->H attack) increase 3.2 times than ischemic type and in ischemic stroke (I-->I attack) 3.6 times increased incidence of second ischemic attack. CONCLUSION: The recurrence rate of stroke was 12.4% (59 of 475 patients). If the first stroke is hemorrhage or infarction, the next stroke would have high potentiality of hemorrhage, or infarction. The possibility of same type in second stroke increase over 3 times. In H-->H group, the time interval between first and second stroke was shorter and the age of onset was earlier than in I-->I group. Moreover, the infarction was more frequent than hemorrhage in multiple strokes. There was a correlation in lacunar type infarction between first and second attack.
