The chest radiographs and angiograms were retrospectively evaluated in 47 patients with pulmonary atresia (PA) and ventricular septal defect (VSD) to determine the characteristic findings of major aortopulmonary collateral arteries (MAPCSs) on the chest radiographs. Of 47 patients, 23 had MAPCAs and 24 had only PDA for blood supply of whole right and left lung. Chest radiographs enabled identification of 16 of 23 patients with MAPCAs. The most common finding of MAPCAs was inappropriately large peripheral pulmonary vasculature (n=16, 69.6%). The other findings were tortuosity of pulmonary vasculature (n=12, 52.2%), focal unevendistribution of pulmonary vasculature (n=12, 52.2%), and two descending pulmonary arteries (n=4, 17.4%). When chest radiographs showed two or more findings of MAPCAs, MAPCAs could be differentiated from PDA with statistical significance (p<0.005). It is concluded that chest radiographs may help to identify MAPCAs before angiography if two-dimensional echo ardiography suggests PA with VSD.

It is thought to be reliable roentgenologic sign of pulmonary plethora that the diameter of anterior segmental artery(d-ASA) is larger than that of anterior segmental bronchus(d-ASB). To evaluate the reliability of this sign, we compared d-ASA with d-ASB on chest rentgenograms of 100 normal adults. Of the total 105 cases. d-ASA was larger than d-ASB in 40 cases (38.1%), smaller than d-ASB in 34 cases(32.4%) and equal to (d-ASA and) d-ASB in 31 cases(29.5%). The ratio(ABR) and difference between d-ASA and d-ASB ranged from 0.70 to 1.58(mean, 1.05±0.30) and from -1.85mm to +2.45mm(mean of absolute value, 0.75mm±0.57). These results showed that the relationships between d-ASA and d-ASB were variable. Conclusively, d-ASA may be larger than d-ASB in even normal adults and mild degree of pulmonary plethora cannot exectly evaluated with this findings only.

BACKGROUND: The afferent and efferent pathways of fentanyl cough response (FCR) and central organization are poorly understood at present. The aim of this study was to investigate the pretreatment effects of morphine, propofol, atropine, and midazolam on FCR. METHOD: The 120 healthy patients were randomly assigned to six equal pretreatment groups. They received 2ug/kg fentanyl rapidly through a peripheral venous catheter. The patients in each group were pretreated before the time necessary for peak plasma levels with different drugs as follows: group 1, no premedication; group 2, morphine 0.05 mg/kg iv; group 3, morphine 0.05 mg/kg iv naloxone 0.01mg/kg iv; group 4, propofol 0.5 mg/kg iv; group 5, atropine 0.01 mg/kg iv; group 6, midazolam 0.05 mg/kg iv. The patients were observed for any coughing or side effects, including oxygen desaturation, bronchoconstriction, chest wall rigidity and seizure. RESULT: 40% of patients in group 1 (control) had a cough response to fentanyl. Group 2 (morphine) and group 3 (morphine naloxone) showed a reduced FCR of 10%. The incidence of coughing was 60% of the patients in group 4 (propofol), 30% in group 5 (atropine), and 40% in group 6 (midazolam). These were not statistically significant. CONCLUSION: FCR is not altered by pretreatment with propofol, atropine, or midazolam, but morphine inhibits cough response and this antitussive effect was not antagonized by naloxone.

BACKGROUND: We observed fentanyl known as centrally-acting antitussive agents provoke a cough response in some patients at induction of anesthesia. This may be of clinical importance. METHOD: 121 patients (ASA class I) were assigned randomly to 4 groups. Each group was given different doses of fentanyll Group 1 (n=30); 0.5ug/kg, Group 2 (n=30); 1ug/kg, Group 3 (n=33); 2ug/kg, Group 4 (n=28); 4 g/kgl, within 1 second through a peripheral venous cannula before induction of anesthesia. All patients were observed carefully in order to detect a cough response and any side effects. RESULT: The incidences of FCR (Fentanyl Cough Response) were 0% in Group 1, 10.0% in Group 2, 30.3% in Group 3, and 39.3% in Group 4. The ED50 of FCR was 4.25ug/kg. The mean onset-time from the end of fentanyl administration to the beginning of coughing was 12.5 seconds. FCR was decreased with aging, but not affected by weight, height, or smoking. Other serious side effects were not accompanied. CONCLUSION: Fentanyl can evoke the pulmonary chemoreflex dose-dependently and the ED50 was 4.25 g/kg.

Real-time ultrasonogram was performed in 31 Pt. with CHPS, who was admitted at the pediatric department of Wonkwang University hospital from January 1991 to June 1993. Those who had positive results of pyloric volume for diagnosis of CHPS and were confirmed by surgery. The results were at follows: 1) The average ultrasonographic measurements of pyloric muscle thickness, pyloric diameter, pyloric length were 4.9+/-1.09mm, 14.42+/-2.69mm, 19.17+/-2.37mm, and pyloric volume was 3.26+/-1.39ml. 2) The diagnostic reliabilities with the ultrasonographic measurements of muscle thickness (>4mm), pyloric diameter (>12mm) and pyloric length (>15mm) by Stunden's criteria in 31 cases were compared, which were not significant difference among them. 3) In ultrasonographic measurements of 31 cases for diagnosis of CHPS, positive results with 3 parameters were 80.6% and with 2 parameters and double tract signs were 87.1%. So. we conclude pyloric volume greater than 1.4ml was the most reliable parameter, which was satisfied 100% with diagnosis of CHPS.

BACKGROUND: Korean Journal of Anesthesiology was published in 1968 and its volume has been increased every year. The purpose of this study was to investigate and to clarify the trend of increasing volumes for 28 years (1968~1996) as quantitative analysis. METHODS: Using computerized index of Korean Journal of Anesthesiology (""ART""), the trend, volumes and cumulative records (top ranked 22 frequently cited key words, 16 persons and 10 departments of University) were calculated. Some key words such as ""Anesthetic techniques: spinal, Anesthetics, intravenous:, Anesthetics, volatile: halothane, Complications:"" was traced every year for grasping the trend of academic concerns. RESULTS: 1. Total volumes of articles were about 3,000 (1968~1996). The volumes were increased slowly until 1976 and steeply since 1986. 2. The ratio of clinical case reports has been decreased every year. 3. Key words ""Anesthetic techniques"", ""Surgery"" and ""Complications"" were more frequently cited than the others. 4. Tracing some key words showed their vitality in anesthetic fields. 5. The personal top ranked number of records revealed each author's contribution to Korean Journal of Anesthesiology and the number of records in each department of University could be used as an index of academic activity. CONCLUSIONS: The extent of the increasing volumes was great especially from 1986 to 1996 and the proportion of original articles has been increased every year. The frequency of the investigated key words showed their own vitality in the field of anesthesiology. The rank according to personal and departmental records suggested the possibility of reflecting a measure of academic concerns and activity.

V.parahaemolyticus or V.alginolyticus infections are usually associated with consumption of raw or undercooked shellfish, contaminated food, and exposure of wounds to warm seawater. V.parahaemolyticus causes gastroenteritis(the most common syndrome), wound infections, and septicemia. V alginolyticus occasionally causes extraintestinal infections in humans. so far, the authors have not found the report of V.parahaemolyticus and V.alginolyticus isolation from a patient. So, we report a case of concurrent isolation of V.parahaemolyticus and V.alginolyticus from a patient who had a history of intestinal diarrhea and vomiting.
