BACKGROUND: The purpose of this study is to assess the ability of dipyridamole99mTc-MIBI SPECT to identify and localize coronary artery disease(CAD). METHODS: The study population consists of 60 patients(37 males, 23 females : mean age 57+/-10 years) including 30 with prior myocardial infarction who underwent both dipyridamole99mTc-MIBI SPECT and coronary angiography for the evaluation of chest pain. RESULTS: The sensitivities for detection of CAD(> or =50% and > or =70% coronary stenosis by angiography) by dipyridamole99mTc-MIBI SPECT are 96% and 98% respectively, and specifities are 71% and 73% respectively. The sensitivities for detection of individual diseased vessels(> or =50% and > or =70%) are 79% and 90% for left anterior descending artery(LAD), 53% and 59% for left circumflex artery(LCX), 45% and 53% for right coronary artery(RCA), 64% and 77% for LCX/RCA, 63% and 72% for total. The specificities for detection of individual diseased vessels(> or =50% and > or =70%) are 62% for LAD, 98% and 98% for LCX, 92% and 89% for RCA, 91% and 89% for LCX/RCA, 87% and 86% for total. The concordances for ditection of individual didseased vessels beteen coronary angiography and dipyridamole99mTc-MIBI SPECT are all fair for SAD(Kappa=0.4 in > or =50% stenosis, 0.54 in > or =70% stenosis)LCX(Kappa=0.56,0.63),RCA(Kappa=0.4,0.44) and LCX/RCA(Kappa=0.56,0.67). CONCLUSION: Dipyriddamole99mTc-MIBI SPECT appers to be an useful noninvasive test for both identification and localization of coronary artery disease.

Atotal of 26 patients diagnosed as diffuse axonal injury(DAI) between Nov. 1993 and Dec. 1995, were evaluated retrospectively with special attention given to MRI findings. In clinical aspects, there was male predominance(1.9:1) with the mean age of 28.5 years. The clinical grades based on the Glasgow coma scale(GCS) score were classified as mild(13-15), moderate(9-12) and severe(3-8). The duration of hospitalization and loss of consciousness(LOC) at admission were well correlated with the severity of clinical status. As regards the outcome of patients, twenty patients(77%) recovered as alert, but three patients(12%) died of sepsis. Short duration of LOC less than one day and young age of less than 10 years were good prognostic factors. The MRI findings of DAI were divided into three grades; in grade 1, there was small scattered lesions in the white matter of the cerebral hemisphere, in grade 2, focal lesion in the corpus callosum, and in grade 3, there was an additional focal lesion in the brain stem. The final outcome of grade 3 was poor, but in grade 2, there was wide spectrum between initial clinical status from alertness to semicoma and relative good result.

Controlled mechanical ventilation with positive end-expiratory pressure(PEEP) is a widely accepted method for the treatment of acute respiratory failure. But artificial ventilation with large tidal voume, high airway pressure and an inspired oxygen concentration of l00% are necessary for adequate arterial oxygenation in severe acute pulmonary parenchymal failure. It has been suspected that such therapy may cause irreversible pulmonary damage. The extracorporeal respiratory support has been called extracorporeal membrane oxygenation (ECMO), extracorporeal CO, removal(ECCO2R) or extracorporeal lung assist(ECLA). They are prolonged venoarterial(VA) or venovenous(VV) bypass for the refractory hypoxemia which provides the diseased lung with rest. The respiratory rate can be lowered down to about 4~8 rates/min during ECLA. PEEP is known to improve the ventilation perfusion distribution with alveolar recruitment. Low frequency positive pressure ventilation is accompanied by PEEP to keep alveoli open during ECLA. The level of PEEP must be determined adequately because high PEEP may decrease the cardiac output especially during VV ECLA. The experimental model for acute respiratory failure was induced by the intravenous injection of oleic acid 0.07ml/kg on six mongrel dogs(15.8+/-0.7kg). After values of arterial oxygen saturation(SaO2) and end-tidal CO2(E(T)CO2) were stabilized on the monitor, we measured control values of hemodynamic parameters. The stepwise increase of PEEP from 5 cmH2O to 15 cmH2O via 10 cmH2O was followed by the comparison of the respective hemodynamic values at each PEEP with control. Compared with control, PEEP of 5 cmH2O did not cause any changes and PEEP of 15 cmH, decreased cardiac output. At PEEP of 10 cmHO, the cardiac output and oxygen flux was maintained with normoxia. It was concluded that PEEP of 10 cmHO can be applied to clinical VV ECLA.

Spontaneous migration of the shunt catheter into the posterior cranial fossa is very rare complication of lumboperitoneal shunt operation. The authors report a case with communicating hydrocephalus following ruptured intracranial aneurysm for which a lumboperitoneal shunt was placed. Four years later, she was presented with low back pain after the slip-down in jury, and radiologic studies revealed compression fracture at T12 and intracranial migration of shunt catether into the posterior fossa. From our knowledge, there is only one other such case reported in the literature.

Blow-out fracture is frequently encountered in facial bone trauma. And the frequency of medial orbital wall fracture in Asia is high. Various approaches have been reported for medial orbital wall fractures. The field of medial orbital surgery is difficult due to lack of visualization of fracture site, blind dissection of orbital wall, susceptibility of injury of orbital structures. Recently, endoscopic reduction of orbital wall was provided good fuctional and cosmetic results. In order to address this shortcoming we have explored the use of endoscopic external short scar approach in medial orbital wall dissection to allow direct visualization of orbital content and nearly whole fracture components. In this study a direct local approach through a 2cm, modified Z-shaped incision on superior medial orbital area was used as a consistent method to reconstruct medial blow-out fractures. The incision line consist 3 limbs. The angle of the limbs is to 110 degrees. First, 1cm sized line exsists frontonasal line. Second, 5mm sized 2 limbs of the incision line were placed parallel or oblique to the relaxed skin tension line. During the follow-up period of 6 to 12 months, excellent functional and cosmetic results were observed with an inconspicuous scar. Therefore, a direct external short scar incision approach with endoscope on the superior medial orbit may be a consistent method to gain the surgical goal in treatment of blow-out fractures of the medial orbital wall.

PURPOSE: There were no accurate data of hematologic changes in the high school students in Korea since 1980'. Because of rapid growing of Korean students recently, it is necessary to reevaluate Korean data. So we compared hematologic changes in the students of general (GHS) and athletic high school (AHS) in Seoul city. METHODS: We reassured red cell count (RBC), hemoglobin (Hb), hematocrit (Hct), and related hematologic factors in the 452 GHS (male 290, female 162) as control group and the 138 AHS (male 70, female 68) as exercised group. Hematologic comparisons were performed between the students of AHS and GHS and the male and female students with t-test. RESULTS: 1) Values of RBC, Hb, Hct, MCHC, RDW were 4.6+/-0.3x1012/L, 13.4+/-1.2g/dL, 41.5+/- 3.4%, 32.2+/-0.5g/dL, 12.1+/-0.9% respectively in the male AHS and 5.2+/-0.3x1012/L, 15.2+/- 1.0g/dL, 46.7+/-3.0%, 32.5+/-0.5g/dL, 12.3+/-0.6% respectively in male GHS, and there were significant between compared data. 2) Values of RBC, Hb, Hct MPV were 4.5+/-0.3x1012/L, 13.6+/-1.2g/dL, 40.5+/-3.2%, 9.0+/- 0.6fl respectively in the female AHS and 5.0+/-0.5x1012/L, 14.9+/-1.3g/dL, 44.8+/-3.4%, 8.7+/- 0.8fl respectively in the female GHS, and significance were between compared data. 3) Values of MCH, MCHC, RDW, MPV were 30.1+/-1.8pg, 33.6+/-1.1g/dL, 12.8+/-1.1%, 9.0+/-0.6fl respectively in the female AHS and 29.3+/-1.8pg, 32.2+/-0.5g/dL, 12.1+/-0.9%, 8.7+/-0.9fl respectively in the male AHS, and there were significant between compared data. 4) Values of RBC, Hct, MCH, MCHC, RDW, PLT were 5.0+/-0.5x1012/L, 44.8+/-3.4%, 30.0+/-2.1pg, 33.4+/-1.1g/dL, 12.7+/-1.0%, 29.8+/-5.8x104/mm3 respectively in the female non-AHS, and 5.2+/-0.3x1012/L, 46.7+/-3.0%, 29.4+/-1.4pg, 32.5+/-0.5g/dL, 12.3+/-0.6%, 28.7+/- 5.8x104/mm3 respectively in the male non-AHS, and there were significant between compared data. CONCLUSIONS: Among the high school students, exercise caused several hematologic changes that were significant decline of the values of RBC, hemoglobin, hematocrit compared to control group regardless of sex. In female students, their values of MCH, MCHC, RDW were significantly increased compared to male students regardless of exercise.
