BACKGROUND: Although determination of Doppler echocardiographic transmitral inflow patterns(DETIP) is used as an indrect method assessing LV diastolic function. It is known that DETIP can be affected by certain hemodynamic variables. The aim of this investigation is to assess the serial changes of DETIP and to determine the relation of DETIP with clinical parameter such as initial left ventricular end-diastolic volume(LVEDV), ejection fraction(EF), Killip class and thrombolytic therapy in acute myocardial infarction (AMI) patients. METHOD: Four serial Doppler and 2-D echocardiographic studies were performed at 1 day, 1 week, 1mouth, and 3 months after development of AMI in 24 patients(M:F=19:5, aged 58+/-11 year , 15 anterior MI) and 13 normal adults (aged 47+/-9 years) as reference group. On admission 14 patients were in Killip class I and 10 patients in class II. Thrombolytic therapy with IV urokinase were done in 11 patients. E velocity, pressure half-time (PHT), and isovolumic relaxation time(IVRT) were analyzed and LV systolic function was determined in apical 4 chamber view. RESULTS: DETIP did not change until 1month after development of AMI. However, E/A ratio was decreased, and PHT and IVRT were increased at 3 months after AMI. Doppler transmitral flow parameters were not related with Killip class and LV systolic function. Patiens who recieved urokinase intravenously and who had greater intial LVEDV(>118cm3) showed higher E/A ratio and shorter PHTand IVRT than those who did not. These findings indicate that changes in Doppler transmitral inflow pattern in AMI patients are not uniform over a period of 3 months and thrombolytic therapy causes favorable effect on Doppler transmitral flow parameters. CONCLUSION: Changes in Doppler trasmitral inflow pattern may be variable over post-AMI period and this should be taken into account in evaluating LV diastolic function after AMI. Thrombolytic therapy may improve LV diastolic function in AMI patients.

BACKGROUND: Isolated coronary ostial stenosis presumed to be atherosclerosis in origin is a rare condition reported to have peculiar characteristics-that occurs primarily in premenopausal women, low incidence of risk factors, severe symptoms of short duration with absence of collaterals suggesting rapid development. METHODS: From Feb. 1979 to May. 1991, 11 patients with isolated left coronary ostial stenosis were identified among 2520 coronary angiographies and they were presumed to be athreosclerosis in origin by excluding other alleged causes. RESULTS: There were 5 males and 6 females with mean ages of 47.8+/-9.5 and 51.5+/-7.9 respectively. Clinical presentations were stable angina in 4, unstable angina in 6 patients, and unstable angina after myocardial infarction in 1 patient.Number of risk factors per patient was 0.82+/-0.98. Majority showed a relatively short history of angina(mean 3.6+/-2.8 months). Coronary angiographic findings showed collateral circulation in 7 patients-grade III in 5 of them. There was 1 death related to coronary angiography. Coronary artery bypass surgeries were performed in 7 patients and 5 of them were followed for mean 22+/-8 months without coronary events. CONCLUSIONS: In contrast to the previous reports, isolated left coronary ostial stenosis presumed to be atherosclerosis in orign did not showed female predelication and although their symptom durations were relatively short coronary angiographies showed well developed collaterals in the majority of patients.We experienced one coronary angiography related death in this group of patients. Coronary artery bypass surgery is to be recommended in these patients otherwise contraindicated.

BACKGROUND: Coronary artery bypass grafts obtained from internal mammary artery(IMA) have a greater patency rate than do saphenous vein grafts(SVG). The release or production of endothelium-derived relaxing factor(EDRF), which regulates blood flow and inhibits platelets function, may contribute to the higher patency rate of IMA. In order to evaluate the difference between endothelium dependent relaxation in IMA and in grafted saphenous veins, we observed acetylcholine responses of IMAs and SVGs in humans. METHOD: Incremental dose if acetylcholine(Ach:A1-20, A2-50, A3-100microg) or single dose if acetylcholine(A3) were infused into the non-grafted IMA in 16 patients with different clinical presentation of coronary artery disease(3 with stable angina, 2 with acute myocardial infarction 4 with variant angina and atypical chest pain syndrome in 7). After the dose-response to Ach was completed nitroglycerine 200microg was injected into the IMA. Graded dose of Ach (A1, A2, A3) was also infused in 13 grafted saphenous veins(SVG). RESULTS: The overall vascular effects of Ach into the IMA were dilatory responses regardless of different clinical presentation. Two or 3 minutes after Ach injection, the diameter of IMA increased by 9.2%(A1) and 16. 7%(A3) respectively(p<0.01). Maximal dilatory response after A3 was comparable to that after nitroglycerin injection. Angiographically normal segements of SVGs also increased its diameter 2 minutes after Ach injection (7.2% with A1, 6.9% with A2 and 8.5% with A3). Thus the degree of relaxation of IMA was more prominent than that of SVGs. Angiographically dicreased segments of SVGs had no response after Ach injection. The overall responses of native coronary artery to Ach was dose dependant constriction. CONCLUSION: Injection of Ach to IMA and angiographically normal segments of SVGs caused vascular dilatation probably due to EDRF response. However the degree of relaxation was more prominent in IMA than in SVG. Angiographically diseased segments of SVGs had no response to Ach injection, suggesting that diseased SVG does not produce EDRF. However the finding of a consistent Ach-induced EDRF relaxation in the SVGs despite of constrictive response in the majority of native coronary arteries might suggest that the regenerated endothelial cell in the SVGs were probably of saphenous vein origin rather than derived from the coronary arterial endothelium.

4.Anesthetic Management for Bilateral Pheochromocytomas in Multiple Endocrine Neoplasia Type 2a.
Korean Journal of Anesthesiology 1992;25(3):631-635
Multiple endocrine neoplasis type 2a(MEN 2a) is an inherited syndrome characterized by the occurrence of medullary thyroid carcinoma, parathyroid hyperplasia and adrenal pheochromocytoma. Adrenal Medullary disease varies from hyperplasia to bilateral multiple pheochromocyomas. In anesthetic view, stabillization of severely fluctuating vital signs has become an issue. But fluctutation of vital signs is not always ween especially large pheochromocytoms, and catecholamine releasing activity is higer in right pheochromocytoma than left. It suggests catecholamine releasing activity is affected by the site of pheochromocytoma and size of pheochromocytoma. Surgically, right adrenalectomy is more difficult than left because the vein of right adrenal gland is shorter and larger in diameter than left and it drians into the inferior vena cava directly, but in lfet, it drains into the reneal vein. Pathologically, nonfunctional of hypofunctional pheochromocytomas which have high ratio of inactivating amines. Another factor is the size of pheochromocytomas. Lager sized pheochromocytomas frequently has necrotic, hemorrhagic, cystic and myxomatous areas compared to smaller ones. In conclusion, case of bilateral adrenalectomy, more careful anesthetic management is required in right adrenalectomy and in smaller pheochromocytomas.

Colitis cystica profunda is a rare benign condition characterized by the presence of mucus-filled cysts in the submucosa of the colon and the rectum. Although it may diffusely involve the entire colon, this disease primarily affects the pelvic colon and rectum. It has rarely been described in the pediatric literature. The surgical treatment has been widely advocated. We report a 7-month-old case, successfully treated by colonoscopic polypectomy without complication. Histologically, components of juvenile retention polyp were mixed with colitis cytsica profunda.

Eosinophilic gastroenteritis, which shows characteristic eosinophilic inflammation, involves any part of the intestine from esophagus to colon. The immunopathogenesis is expected to be associated with IgE-mediated or non-IgE-mediated reaction, but the precise mechanism is not revealed yet. The clinical manifestation is variably dependent on the extent of eosinophilic infiltration. Usually the symptoms, such as abdominal pain, diarrhea, vomiting, wax and wane for a few months result in failure to thrive, which implicates the importance of early detection. Although the diagnosis is made through clinical and histopathologic evidences, we should suspect the illness in a case of anemia, hypoalbuminemia, and peripheral eosinophilia. Recently, we experienced a case of non- IgE-mediated eosinophilic colitis in a 11-year-old male who complained of diarrhea, right lower abdominal pain, body weight loss, was diagnosed with peculiar histopathologic finding of sigmoid colon specimens obtained by sigmoidoscopy.

Chilaiditi's sign is a radiographic term used when the hepatic flexure of colon is seen interposed between the liver and right hemidiaphragm. Mostly asymptomatic, Chilaiditi's syndrome can present with abdominal pain, nausea, vomiting, anorexia, abdominal distension, tender hepatomegaly and change in bowel habits. Uncommon in childhood, the incidence seems to increase with age. We have experienced a case of Chilaiditi's syndrome presenting with vomiting in a 15-month-old boy. The patient recovered uneventfully.

Primary peritonitis usually refers to a bacterial infection of the peritoneal cavity without a demonstrable intra-abdominal source. Most cases occur in children with ascites resulting from nephrotic syndrome or cirrhosis. Rarely, it may occur in previously healthy children less than 7 years of age, usually a girl. Distinguishing primary peritonitis from appendicitis may be impossible in patients without a history of nephrotic syndrome or cirrhosis. Accordingly, the diagnosis of primary peritonitis is made only at laparotomy. We report one case of primary pneumococcal peritonitis in a 27-month-old female who underwent explorative laparotomy to discover the cause of suspicious intestinal perforation and mechanical ileus. Later, pneumococci were cultured in blood and gram-positive diplococci were isolated from the pus of peritoneal cavity.

Intestinal malrotation is a developmental anomaly resulting from embryologic failure of fixation and rotation of the gut and predisposed to midgut volvulus and small bowel obstruction. Acute midgut volvulus is most often encountered in the newborn period. But older children and adults may have a history of intermittent episodes of partial volvulus presenting with recurrent colicky abdominal pain accompanying bilious vomiting. We experienced a case of intestinal malrotation complicated by midgut volvulus presented with recurrent vomiting and abdominal pain in a 6-year-old boy.

Gastroparesis is rare in children and is defined as delayed emptying of gastric contents into the duodenum without mechanical obstruction. We experienced a case of gastroparesis in a 7-year-old boy after a viral illness. He was admitted because of excessive abdominal bloating and diffuse abdominal pain, and was diagnosed by clinical manifestations and measurement of the gastric emtpyting time. He recovered after dietary management and with commbined medication of erythromycin and domperidone in 50 days of illness.
