This study was conducted to investigate the safety of the umbilical venous blood for antologous transfusion in the premature newborn babies. Umbilical venous blood was collected with aseptic technique immediately after delivery from 270 healthy mothers admitted to the Yeungnam University Hospital between March 1,1992 and August 31,1992 . The volume of the blood and the time taken for collecting the blood were measured. Also the hematological and biochemical changes of the blood during storage in the refrigerator of blood band and the incidence of bacterial contamination were studied. It took 67.6+/-25.9 seconds on the average for collecting the blood from an umbilical vein and the average volume of the blood was 77.1+/-23.2ml which would be sufficient volume for one time transfusion of 10ml/kg of packed red blood cells for the neonates. The hemoglobin and hematocrit values did not change significantly during storage for three weeks. Thus significant hemolysis did not seem to occur during storage. However, platelet counts decreased significantly from 248+/-59x10E3/mm3 to 193+/-47x10E3/mm3(p<0.01). Although plasma calcium level was not changed (8.4+/-0.9mg/dL), sodium was decreased significantly from 184.3+/-11.1mEq/L to 170.9+/-13.9mEq/L(p<0.01) and potassium was incresed from 5.0+/-1.0mEq/L to 26.7+/-4.8mEp/L.(p<0.01). Plasma glucose level was decreased from 521.7+/-106.7mg/dL to 294.3+/-120.8mg/dL (p<0.01), blood pH and bicarbonate concentrations were decreased significantly from 6.825+/-0.110 to 6.378+/-.087 and from 13.5+/-1.6mEq/L to 2.1+/-1.0mEq/L respectively (p<0.01). The smear of the umbilical venous blood and peripheral blood of the neonates stained by KleihauerBetke method revealed no significant differences in the percentages of adult red blood cells. Also there were no differences in the percentages of adult ted blood calls in the umbilical venous blood samples according to time for collection. The degree of decrement of hemoglobins (1.2gm/dL) after delivery in the mothers who had sampling of the umbilical venous blood was not different from that in the mothers who didn't hava sampling. The bacterial contamination rate of the umbilical venous blood was 3.5% (95% confidence interval was from 0.7 to 6.3). It seems to be safe to use the umbilical venous blood in the neonates for autologous transfusion but confirmation of bacterial contamination by culture is necessary.

PURPOSE: It is not easy to determine the cause of pulmonary consolidative lesion. Even without any definite mass, malignancy cannot be ruled out. And sometimes, it is difficult to differentiate tuberculosis from pneumonia. To differentiate malignant consolidative lesion from benign one, we studied patterns of air bronchogram, mucoid impaction, and computed tomographic anglogram etc. MATERIALS AND METHODS: Fifty seven cases of pulmonary consolidative lesions(23 cases of malignancy,34 cases of benign lesion) were retrospectively reviewed by three radiologists. RESULTS: Among the 28 cases which showed a little air bronchogram(less than 1/3 of the whole lesion in volumetric measure with the eye) 19 cases were malignancy and nine cases were benign lesions. All of the 12 cases which showed profound air bronchogram over 2/3 of the whole lesion were benign lesions. Bronchiectasis was detected in 31 cases(four of malignancy and 27 of benign lesions). Among the 20 cases which didn't show the mucoid impaction five cases were malignancy and 15 cases were benign lesions. Out of eight cases with mucoid impaction filling the long segments(branching tree shape), seven cases were malignancy and one case was benign lesion. So called CT anglogram was detected in nine cases of malignancy and two cases of benign lesions. All of nine cases of malignancy showed CT anglogram which was like arborizing tree. CONCLUSION: Scanty air bronchogram, profound arborizing mucoid impaction and/or CT angoigram within consolidative lesion could suggest malignancy.

It is well known that anatomic variations affecting the ostiomeatal unit (OMU) become one of the causes of mucosal abnormalities of paranasal sinuses (PNS). Findings of coronal plane CT scans of PNS were analyzed in 95 patients with sinusitis or sinusitis-like complaints. Anatomical variations were seen in 88 cases of 60 patients. Mucosal abnormalities were seen in 27 of 47 cases with concha bullosa, 23 of 37 cases with enlarged ethmoid bulla, 8 of 33 cases with Agger nasi, 20 of 26 cases with nasoseptal deviation, 7 of 8 cases with Haller cell, 3 of 6 cases with duoble middle turbinate, 4 of 6 cases with medially bent uncinate process, 1 cases with laterally bent uncinate process, and 33 of 40 cases with mixed variations. Mucosal abnormalities in cases with antomical variations were detected in 61 cases, including maxillary sinus(51 cases), anterior ethmoid sinus (26 cases), frontal sinus (4 cases), and mixed (32 cases). Mucosal abnormalities without anatomical variations were detected in 13 cases involving maxillary sinuses (7 cases), anterior ethmoid sinuses (5 cases), and frontal sinus(1 cases). In conclusion, as coronal plane CT scan has the capability of dolineating anatomical variations and mucosal abnormalities of PNS, it is considered useful in evaluating the treatment and prognosis of chronic or recurrent sinusitis.

BACKGROUND: Primary stenting as a direct reperfusion procedure after acute myocardial infarction might reduce recurrent myocardial infarction and target vessel revascularization. However, result of long or multiple stenting in the long or tandem lesions were not known. METHOD: From Jan. 1996 to Dec. 1998, patients with acute myocardial infarction including cardiogenic shock were undergone primary stenting using long or multiple stent. The clinical end points were death, recurrent infarction, subsequent bypass surgery, or repeat angioplasty of the infarct-related vessel. The results were compared with age, sex, lesion, and risk matched standard stenting group. RESULT: Baseline characteristics were similar for the 20 patients who underwent standard length stenting and the 13 patients who underwent long or multiple stenting. Stent diameter was similar in two group (3.4+/-0.3 mm vs. 3.5+/-0.4 mm, p=0.65), but total stent length was longer in long or multiple stenting group (15.5+/-1.8 mm vs. 40.18.4 mm, p=0.01). Average numbers of stent using in multiple stenting were 1.5+/-0.7. Stenting in the infarct-related artery was successful in all patients randomized to stent treatment. At 6 months, the incidence of the primary end point was 25% (5/20) in the standard stent group and 31%(4/13) in the long or multiple stent group (p=0.5). CONCLUSION: Outcomes of long or multiple stenting including mortality, recurrent myocardial infarction and target vessel revascularization was similar to standard stenting. Long or multiple stenting after acute myocardial infarction may possible procedure in some selective cases having long or tandem lesion.
