Endoscopic retrograde cholangiopancreatography(ERCP) is a new diagnostic method for pancreatic and biliarydiseases which has been made possible by the development of fiberoptic duodenoscopy. It has been thought that ERCPwell serve an important role in the early detection of pancreatic cancer, but in order to detect minor lesions ofthe pancreas and improve the diagnostic accuracy of resectable pancreatic cancer, Endoscopic RetrogradeParechymography of the pancreas (ERPP) was developed recently. The authors analyzed 117 cases of ERCP performed atthe Kwangju Christian Hospital between Jan. and Dec. 1980, and compared them with the final diagnosis. The resultswere as follows; 1. Out of 117 cases, successful visualization of the duct of concern was achieved in 105 cases.Of these, 25 cases were ERPP. 2. The ratio of males to female was 1.44:1. Most patients were in the 4th to 6thdecade. 3. The commmonest clinical manifestations were upper abdominal pain (77cases), jaundice(23 cases),indigestion, vomiting and abdominal mass, in order of frequency. 4. Out of 46 cases of suspected pancreaticdiseases, the pancreatic duct was visualized in 36 cases, and 24 cases revealed pathognomonic findings. These werediagnosed as 16 cases of pancreatic cancer, 4 cases of chronic pancreatitis, 2 cases of pancreatic pseudocyst and2 cases of periampullary cancer with pancreas invasion. In pancreatic cancer findings were; encasement, localdilatation, delayed excretion, poor filling, obstruction of pancreatic duct, accompanying C.B.D. obstruction orstenosis and so called double duct sign. The chronic pancreatitis findings included; ductal dilatation (with orwtihout) obstruction, tortuosity with dilated saccular lateral branching, stone formation and the parenchymalfilling defect. 5. Out of 71 cases of suspected biliary tract diseases, the biliary tract was visualized in 57cases, and in 31 cases abnormalities were suggested; such as 20 cases of biliary stone, 1 cases of ascariasis, 1case of clonorchiasis with cholangitis, 1 case of clonorchiasis with stone, 2 cases of C.B.D. ca. 2 cases of G.B.ca, 3 cases of intrahepatic disease, 1 case of stones in the biliary tree with ampullary ca. 6. Complications ofERCP and ERPP were extremely raare. Transient abdominal distention, abdominal discomfort and elevated serumamylase were noted, but were not clinically significant.

Endoscopic Retrograde Cholangiopancreatography(ERCP) is one of the important diagnostic methods for pancreaticcancer. It has an essential role in the early detection of pancreatic cancer. The ERCP findings of 35 cases ofpathologically proven pancreatic cancer during the period of five and a half years from April 1977 through Nov.1982 at Kwangju Christian Hospital were studied. The resuls were as follows; 1. The ratio of male of female was3.4:1, and most of the patients were over 40 years of age (88.5%). 2. The locations of the lesions were the headin 28 cases (80%), the body in 7 cases(20%), and the ail in 3 cases (8.6%). 3. The ERCP findings of pancreaticcancers were as follows; 1) Encasement or obstruction of common bile duct, 18 cases (51.4%). 2) Obstruction ofpancreatic duct, 16 cases (45.7%). 3) Irregular stenosis of pancreatic duct, 8 cases (22.3%). 4) Double duct sign,7 cases (20%). 5) Diffuse narrowing of pancreatic duct, 2 cases (5.7%).

Preoxygenation is a standard anesthetic technique which prevents significant hypoxemia during the induction of anesthesia. Complete oxygenation is especially important in clinical situations of difficult intubation or in patients with decreased FRC, and in siturations where oxygen saturation is critical. During the induction of anesthesia in children, airway obstruction and apnea are associated with rapid development of hypoxemia. The decreasing speed of oxyhemoglobin saturation was faster in smaller infants than bigger infants. The most important factor determining the speed with which hypoxemia develops in healthy children is probably the oxygen reserve contained in the lungs and its relation to the oxygen consumption of the child. With deaeasing age, the arterial oxygen consumption increases and the ratio of FRC to body weight decreases. Due to the anatomical structure of an infant's upper airway, it is more difficult to obtaine patient airway in infants than in children. During repeated atttempts to intubate the trachea or while waiting for recovery from laryngeal spasms hypoxia can occur easily resulting in visible cyanosis in infants. This study was carried out to measure the time permissible for apnea before occurance of hypoxia following full oxygenation. The subjects consisted of 6 randomly selected infants 1-2 month of age, 4.6+/-0.6 Kg of body weight with no abnormalities of cardiorespiratory functions. After the intramuscular injection of atropine, patients were anesthetized through mask using oxygen and halothane. SpO2 and pulse rates were recorded throughout the study. After the patients were intubated, a plug was placed on the distal end of the tube to induce obstructive apnea. As soon as SpO2 decreased to just below 90%, the patients were ventilated again. In 2 of the infants, the time required to obtaine 90% saturation was 60 seconds. Within less than 70 seconds, four out of 6 infants had SpO2 below 90% and SpO2 below 80% were noticed in 3 cases. After the reestablishment of ventilation, SpO2 returned to the preapneic value within 10 second in all subjects. There was no evidence of increasing pulse rate as SpO2 levels decreased. However, pulse rate decreased in all subjects thoughout the study. In summary, maximum time permissible for apnea in neonate and young infant is approximately one minute. Furthermore, tachycardia should not be used as a sign for the onset of hypoxia.

Purpose: The Life Transition Scale (LTS) consists of 24 items that assess the life transition process of parents of autistic children. This study aimed to examine the validity and reliability of the LTS in parents of children with a wide spectrum of disabilities. Methods: Data were collected from 260 parents of children with disabilities through self-report questionnaires. Validity was examined using exploratory and confirmative factor analysis to determine the factor structures of the LTS; socio-demographic differences in LTS scores were examined using the t-test or ANOVA. Reliability was examined using Cronbach's ⍺ coefficient. Results: A four-factor structure was validated (x2=640.0, p<.001, GFI=.81, RMSEA=.07, NNFI=.89, CFI=.89, PNFI=.74, Q [x2/df]=2.60). The validity of the LTS was verified by exploratory factor analysis, with factor loading ranging from .30 to .80. There were significant differences in the accepting phase according to children's and parents' age and the type of disability, and in the wandering phase according to parental gender, educational level, job, and socioeconomic status. The Cronbach's ⍺s for the reliability of each of the four structures were acceptable, within a range of .80~.90. Conclusion The LTS is a valid and reliable measurement to assess the life transition process of parents with disabled children.

Postoperative atrial arrhythmia after thoracotomy is relatively common, with a reported incidence ranging from 8% to 30%. These arrhythmias may cause hypotension, congestive heart failure and lengthen the period of postoperative hospitalization. The most important precipitating factor is atrial dilation and identified risk factor is an advanced age of the patient. The effect of various prophylactic regimens to reduce atrial arrhythmias is controversial. We report a case of postoperative atrial fibrillation in a 73 year-old female patient undergoing repair of esophageal hiatal hernia.

BACKGROUND: Dobutamine and amrinone, phosphodiesterase-III inhibitor, are known to have both inotropic and vasodilatory properties. We evaluated the effects of both drugs on systemic and pulmonary hemodynamics in patients with pulmonary hypertension (PH). METHODS: With Institutional Review Board approval, 45 patients whose mean pulmonary arterial pressure was greater than 30 mmHg were studied. After sternotomy under the steady state of anesthesia and controlled ventilation (30 mmHg < PaCO2 < 40 mmHg), patients recieved one of following drugs for 30minutes (min); dobutamine 5.0ug/kg/min (Group I), low dose amrinone (loading dose 1.0 mg/kg, followed by infusion 7.5 g/kg/min, Group II) or high dose amrinone (loading dose 2.0 mg/kg, followed by infusion 10 g/kg/min, Group III). Hemodynamic variables were measured at 10 min and 30 min after start of infusion. RESULTS: Dobutamine didn't decrease pulmonary arterial pressure (PAP) and cause no hemodynamic change while low and high dose amrinone reduced PAP and especcially decrease of PAP in low dose amrinone group was statistically significnat. High dose amrinone increased cardiac index (CI) and decreased both systemic vascular resistance index (SVRI) and central venous pressure (CVP) more significantly than control value. CONCLUSIONS: In patients with chronic right ventricular failure associated with PH, amrinone may decrease the PAP and improve cardiac performance more effectively than dobutamin does. Increment of dosage of amrinone may not result in significant reduction of PAP.

A 51-yr-old man underwent mitral valve replacement and tricuspid valve repair due to mitral and tricuspid regurgitation under cardiopulmonary bypass. The pulmonary artery (PA) catheter was inserted easily via right internal jugular vein and functioned well until the end of surgery. The surgery was uneventful and patient's hemodynamics were stable both in the operating room and intensive care unit. All PA catheter functions were normal, but the balloon rupture was suspected because it was unable to obtain pulmonary capillary wedge pressure. On attempted removal of the PA catheter at the next day, considerable resistance was encountered and pulmonary artery tracing was dampened. A followed-up chest X-ray revealed the catheter to be in the right pulmonary artery without evidence of knotting. Suture related entrapment was suspected, and on reoperation, PA catheter was found to be sutured at the left atriotomy site. The PA catheter was removed under cardiopulmonary bypass and revealed a hole between proximal port and thermal filament.

A 39 year old man suffering from pheochromocytoma and coronay artery obstruction diseases was scheduled for coronary artery bypass graft surgery before an adrenalectomy. General anesthesia was induced with fentanyl and midazolam and maintained with intermittent administration of fentanyl and low concentraion of isoflurane. At 5 minutes after commencement of cardiopulmonary bypass (CPB), the mean arterial pressure suddenly elevated to 150 mmHg. Sodium nitroprusside and labetalol were administered rapidly, however, mean arterial pressure could not be lowered below 100 mmHg. After release of aortic cross clamp, the electrocardiography showed tachycardia (150 beats/min) with wide QRS and systolic arterial pressure elevated to 180 mmHg. Antiarrhythmic drugs, inotropic and antiischemic drugs were administered. Thereafter tachycardia was disappeared and systolic arterial pressure was lowered below 150 mmHg. We observed the paroxysmal hypertension and tachycardia during CPB that is considered to be attributed to the presence of pheochromocytoma. Therefore we suggest that continuous thoracic epidural anesthesia and pulsatile perfusion during CPB could be helpful in a patient with pheochromocytoma undergoing coronary artery bypass grafting.

BACKGROUND: Osteopontin (OPN) is a glycoprotein and it participates in cell-cell and cell-matrix interactions. In vitro studies suggest that the OPN expression is associated with tumor metastasis, and especially with the metastasis of osteotropic tumors originating in breast, prostate and lungs. Since no human tissue study has suggested the means by which OPN participates in the tumorigenesis, angiogenesis, progression and metastasis of renal cell carcinoma (RCC), we evaluated the expression and prognostic significance of OPN in RCC. METHODS: Immunohistochemistry was performed with using the primary antibody for OPN on the archival paraffin-embedded tissue microarray specimens from 51 RCC patients who underwent radical or simple nephrectomy. RESULTS: In the normal kidney specimens, OPN was expressed in a few compressed distal tubules adjacent to the RCCs. In RCCs, the OPN expression was elevated in larger tumors (p<0.05) and in the tumor with low microvessel density (p<0.01). In the present study, univariate analysis indicated that stage, tumor size, lymph node and distant organ metastasis are significant prognostic factors for disease free survival (DFS) in RCC patients (p<0.01), but OPN is not (p=0.0661). Multivariate analysis indicated lymph node metastasis is the independent prognostic indicator of DFS (p<0.05). CONCLUSION: Though this study has statistical limitations, these results suggest OPN plays a role in tumor progression and metastasis and it may act as a potential prognostic indicator to predict the prognosis of RCC patients.

BACKGROUND: Arterial pressure is the most commonly utilized guideline for the management of critically ill patients. However, the site of arterial pressure monitoring can impact the observed pressure. In patients undergoing cardiac surgery, peripheral arterial pressure can underestimate central aortic pressure and vasodilators magnify this phenomenon. There was also a large discrepancy between radial and femoral artery pressure in endotoxemic patients treated with vasopressors or hypothermic patients. We evaluated the effect of the continuous infusion of norepinephrine, the most commonly used vasopressor, on pressure and blood flow in both the brachial and femoral artery in dogs in normal condition. METHODS: Both the brachial and femoral arteries were cannulated for pressure monitoring and the other side arteries were exposed for the measurement of blood flow in 10 dogs. Two doses of norepinephrine (NE), 0.05 microgram/kg/min and 0.1 microgram/kg/min, were infused for 10 minutes each in sequence. Hemodynamic variables and blood flow were measured before the infusion of NE, and immediately after the infusion of the two doses of NE. RESULTS: NE increased both brachial and femoral arterial pressures with no difference between the two pressures. NE decreased blood flow in both brachial and femoral arteries even though cardiac output was maintained constantly which means NE caused the redistribution of blood flow. CONCLUSIONS: Unlike endotoxemic shock conditions or hypothermic vasoconstriction, NE didn't show different effects on pressure monitoring sites regardless of their diameter in normal condition. NE increased blood pressure and decreased blood flow in the same degree in both the brachial and femoral artery.
