PURPOSE: The aim of this study is to better understand the pattern and nature of reverse redistribution (RR) in myocardial perfusion imaging. MATERIALS AND METHODS: In consecutive 20 acute myocardial infarction (MI) patients, frequency of RR was correlated with that of subendocardial MI that was detected by myocardial contrast echocardiography (MCE). RR was judged to be present when there was more than one grade of worsening in perfusion at 24 hr delayed images compared with the initial rest images. MCE evaluated the significant lack of opacification in the subendocardial myocardium relative to the subepi-cardial myocardium to suggest the subendocardial MI. Kendall's nonparametric correlation coefficiency was calculated. RESULTS: Concordant cases were 15 of 20 (75%) and correlation was statistically significant (p=0.0285). CONCLUSION: Our results suggested that RR was correlated with MCE-detected nontransmural MI.

Tufted hair follliculitis is a localized, inflammatory and exudative disease of the scalp characterized by a tufted appearance of the scalp hairs emerging from single follicular openings, and may result in permanent and irreversible scarring alopecia. We report two cases of tufted hair folliculitis in a 53-year-old woman and a 47-year-old man. They had several areas of scarring alopecia with multiple bundles of hairs emerging from single follicular orifices. Histopathologic findings were typical for tufted hair folliculitis. The patients were treated successively with oral antibiotics and with topical application of clindamycin.

This study was performed to observe the elementary body and initial body in the cultured conjuntival epithelial cell, which was co-cultures with Chlamydia trachomatis serotype-D. Following 3 weeks of cultivation of the rabbit conjuntival epithelial cell, Chlamydia trachomatis seretype-D was inoculated into the epithelial cells and co-cultured for 24, 48, and 96 hours respectively. The infected conjunctival epithelial cells was stained with fluorescence-conjugated chlamydial antibody and iodine staining. Regardless of the duration of the cocultivation time, the cultured conjunctival cells showed the positive reaction to immunofluorescent staining and iodine staining. These results indicate that Chlamydia trachomatis can be cultured in the cultured conjuntival epothelial cell of rabbit and iodine staining is a good alternative to the immunofluorescent method.

VSD is the most common congenital carciac malformation and the natural history depends not only on the age ofpatients and the size of defect but the subtype of VSD as well, important factor in clinical management or thosepatients. In 110 patients, with surgically repaired VSD in Yonsei Medical Center in 1984, the subtype of VSDs evaluated by surgical observation were correlated with LV angiogram findings to verify the incidence of subtype inKorean and the diagnostic accuracy to predict the subtype by angiogram. 1. 110 patients included 64 boys and 46 girls, the age ranged from 3 months to 14 years(average 4.6 years old) 2. Angiographic findings were interpretedas follows; a. Perimembranous defects were profiled in LAO 60 degrees LV angiogram and located below the aorticvalve. In inlet excavation the shunted blood opacified the recess between septal leaflet of tricuspid valve and interventricular septum in early phase, in infundibular excavation opacified the recess between anterior leafletof TV and anterior free wall of RV and in travecular excavation the shunted blood traversed anterior portion of TVring, opacified trabecular portion of RV cavity. b. Subarterial type were profilled in RAO 30degrees LV angiogram,just below aortic valve as well as pulmonic valve. Total infundibular defects were profilled in RAO 30degrees andLAO 60 degrees LV angiogram subaortic in location in both views. c. In muscular VSD the profilled angle was variedaccording to the subtype but the defects were separated from the aortic valve as muscular septum interposedbetween the aortic valve and the defect. 3. The incedence of subtype of VSDs evaluated by surgical observationwere as follows. Subaterial type 32 cases(29.1%) Total infundibular defect 5 cases( 4.5%) Perimembranous type 73cases(66.3%) Infundibular excavation 32 cases(29.1%) Trabecular excavation 28 cases(25.5%) Inlet excavation 10cases(9.1%) Mixed 3 cases(2.7%) Muscular type 1 cases(0.9%) Total 63.6% of VSD, were the varieties of theinfundibular septum type. 4. The prediction of VSD subtype accoridng to the angiographic findings described above,were compared to the surgical observation. Diagnostic rate was 100% in perimembranous type, 75% in subarterialtype, 0% in total infundibular type, so 88% of cases were in accordance with the surgical findings.

We studied the angiographic findings in 65 patients wtih congenital pulmonary atresia, ages 4 days to 14 years(mean 3.3 yrs), form 1981 to 1986 at Severance Hospital Yonsei University. 1. 6 had pulmonary atresia with anintact interventricular septum, 38 had it with cardiac anomaly Renodynamically simulating TOF, and 21 associatedwith more complicated cardiac anomalies. 2. In the group with an intact ventricular septum, 5 showed confluentintrapericardial pulmonary artery, all segmental pulmonary arteries connceted to intrapericardial pulmoanryartery. 3. In the group simulating TOF, aorta arose from RV with or without overriding in 35. In 27 patients withconfluent intrapericardial pulmonary artery, 23 had more than 10 segmental pulmoanry arteries connceted tointrapericardial artery and 5 had severely hypoplastic hilar pulmonary arteries. In 11 with nonconfluentintrapericardial pulmonary artery, 4 had more than 10 segmental pulmonary arteries connected to central pulmonaryartery and 9 had severely hypoplastic hilar pulmonary arteries. 4. In the group associated with more complicatedcardiac anomaly, included 8 patients with atrioventricular discordance, 7 with univentricular heart and 6 withtricuspid atresia. In 17 patients with confluent intrapericardial artery, 16 had more than 10 segmental pulmoanryarteries conncected to intrapeircardial artery, one showed severe hypoplasia of hilar pulmonary arteries. Inanother 4 with nonconfluence, no one showed more than 10 segmental arteries conncted to intraperdicardial or hilarpulmonary artery.
