Congenital obstuction of pulmonary vein without anomalous drainage can cause long-standing pulmonary congestion and pulmonary arterial hypertension, and it may include stenosis of individual pulmonary veinsor total pulmonary vein atresia. We reviewed seven cases of pulmonary vein obstruction, five of which accompanied other cardiac anomalies. Right pulmonary veins were involved in all seven cases including one bilateral case. Pulmonary veins were occluded totally in five and partially in three lungs. Pumonary catheterization and angiography were done for diagnosis. Chest radiographs of total occlusion cases showed decreased lung volume, features of pulmonary edema, interstitial lesions, and pleural thickening, which were quite specific, whereas pulmonry venous dilatation was dominant findings in partial obstruction cases. Pulmonary perfusion scans (n=3) showed total perfusion defects in the cases of total occlusion of veins. MR imaging (n=2) demonstrated total occlusion of pulmonary veins in the venoatrial junction in two, and membranous focal obstruction in one lung. Two patients had pneumonectomy and histological confirmation, Although catheterization and angiography are essential for the diagnosis, MR imaging is thought to be useful for the diagnosis of pulmonary vein obstruction.

PURPOSE: To investigate the Doppler ultrasonographic parameters of a carotid ultrasound (CUS) for the stenosis of the intracranial internal carotid artery (IICA). MATERIALS AND METHODS: The authors evaluated 15 patients with normal extracranial ICA, the common carotid artery (CCA), and stenosis of IICA (patient group). The control group consisted of 22 patients with normal findings on a magnetic resonance angiography (control group). All subjects were subjected to a CUS, whereas subjects from the patient group underwent a cerebral angiography. The following parameters were investigated: peak systolic velocity (PSV) and end diastolic velocity (EDV) in ICA, PSV in CCA, resistive index (RI) in ICA, and PSV ratio. Stenosis was measured following an angiography and was graded as follows: normal (0-24%), mild (25-49%), moderate (50-69%), and severe (70-99%). Next, the CUS findings, which reflected the IICA stenosis, were investigated. RESULTS: Of the 74 ICAs, 52 were normal (44 ICAs in the normal group and 8 ICAs in the patient group), 10 had mild stenosis, 8 had moderate stenosis, and severe 4 had severe stenosis. As the stenosis grade increased, PSV and EDV in ICA as well as PSV in CCA, decreased (p value < 0.05); however, the PSV ratio and RI remained unchanged. CONCLUSION: As stenosis of IICA increases, PSV and EDV of ICA and PSV of CCA decreases following a CUS.

A cerebral infarction in a newborn infant is not uncommon and is major cause of neonatal seizure. The author encountered one case of cerebral infarction that was assumed to be related to a portal vein thrombosis, and reports the radiology findings of a neonatal cerebral infarction and portal vein thrombosis.

STATEMENT OF PROBLEM: For a long time, many of denture base acrylic resins have been used for edentulous and partial edentulous patients because of easy manipulation and good mechanical properties, but its esthetic aspect has not been commented enough. Denture base acrylic resins also has caused esthetic problems due to discoloration or staining as in esthetic restoration. Many researches and reports have treated the problems and accomplished esthetic improvement. But these researches and reports dealt with general food colors or beverages, not with fermented foods. PURPOSE: This study is designed to assess what fermented foods, such as soy sauce, gochujang, and toenjang that many of Koreans have taken in, influence on the color and hardness variation of denture base acrylic resins. MATERIALS AND METHODS: For the procedure, twelve disks per 4 denture base acrylic resins were fabricated with a thickness of 2mm and 16mm in diameter. Each seven specimen were measured for discoloration with spectrophotometer, while the others, five specimen, for surface hardness change with Barcol hardness tester, over time. Each 12 specimen were immersed into the 4 beakers of fermented foods(soy sauces, gochujangs, toenjangs, deionized water), and L*, a*, and b* values were measured for the color difference(_E*), on the 1st, 7th, and 28th day with spectrophotometer, with the measurement of surface hardness change. Each data observed was processed statistically. RESULTS: The findings are as follows; Discoloration 1. All of denture base resins was not influenced by the kind of fermented foods, except for QC20. 2. Soy sauce and red pepper paste caused more change for denture base resins than deionized water and soy bean paste, except for Perform. 3. Most significant change was shown in Lucitone199., whereas Perform. results in the least change for all immersed solution, with no statistical significance. Hardness change 1. Barcol hardness values in deposited specimens have been changed low degree, but with significant statistical change according to the kind of food and duration. 2. Lucitone199. has significantly lower Barcol hardness value than others do. CONCLUSION: Based on the above results, it suggests that the habitual intake of fermented foods is not helpful for the color stability of denture base acrylic resins because Soy sauce and red pepper paste mainly caused discoloration and surface hardness change. Particularly Lucitone199. shows specific discoloration and low surface hardness values. Therefore, it is recommended giving caution patients with denture of Lucitone199. especially against the habitual intake of fermented foods like soy sauce and red pepper paste.

We reviewed 28 pts. with testicular tumors admitted to the department of urology, Catholic medical college during last 12 yrs. The results are summarized as follows; 1. Age distribution ranged from 4 months to 59 years old, showing the highest incidence below 10 yrs old (39%). 2. There were 28 cases of testis tumor, and all cases were germ cell tumors which consisted of 9 cases of seminoma, 10 cases of teratoma, 5 cases of embryonal carcinoma, 2 cases of teratocarcinoma. 1 case of seminoma and embryonal carcinoma, and 1 case of choriocarcinoma and seminoma. 3. Serum HCG and AFP were evaluated in 13 cases. All seminoma and teratoma, 1 case of seminoma and embryonal ca. ranged within normal limit. But, among 4 cases of embryonal ca. 2 had elevated serum HCG, and 3 had elevated serum AFP. 1 case of teratocarcinoma and 1 case of seminoma and teratoma had elevated serum AFP and HCG. 4 The clinical stage was A in 21, B in 6, C in 3. 5. Radical orchiectomy was done in all cases, and retroperitoneal lymph node dissection was given for 9 cases. Radiation therapy and chemotherapy with PVB regimen were performed in 10 and 3 cases. 6. On 12 cases follow up study was made. Of them 3 (1 of teratocarcinoma, 1 of embryonal carcinoma, 1 of seminoma and embryonal carcinoma) in stage C were died at 3.3 yrs, 1.2 yrs and 15 days after orchiectomy. And 1 case(teratocarcinoma) in stage A were died at 1.5 yrs. after orchiectomy due to pulmonary metastasis. Remaining 8 cases are alive without evidence of relapse for mean follow up 39.7 months.
