1.Detection of cytomegalovirus DNA in urine culture using polymerase chain reaction.
Journal of the Korean Pediatric Society 1993;36(5):626-633
Polymerase chain reaction (PCR) amplication was used to detect cytomegalovirus (CMV) in tissue culture from the urine of newborns and patients who was suspected CMV infection, Synthetic oligonucleotide primer pairs were used to amplify DNA from the major immediate-early and the phosphoprotein 150 genes of CMV AD 169. Amplified products were detected by gel electrophoresis and by dot-blot hybridization with oligonucleotide probes. We found 12 different tissus culture isolates of CMV after the microimmunoassay using monoclonal antibody to immediate-early antigen. All 12 isolates were positive after PCR amplification. But there was no positive reaction when the same primers and probes were used to amplify herpes simplex virus and human genomic DNA. Twelve urine samples were positive when tested with one or both primer pairs and probes. When compaired tissue culture, detection gel electrophoresis provide a sensitivity of 91% (11/12), dot-blot analysis raised the sensitivity to 100% (12/12). A specificity of both primer was 100%(0/12). We conclude that PCR amplification may be a valuable tool for diagnosing congenital CMV infection.

For the study on the effect of retinoic acid on the formation of palatal rugae and the cleft palate, retinoic acid was administered orally 150mg/kg of body weight by gastric tube at GD 10.5 to Sprague-Dawley rats. The pregnant rats were sacrificed on GD 17.5 under ether anesthesia, and laparatomized. After removal of uterus, the number of pregnant sacs and fetuses were counted. The fetuses weighed, the MEE (medial edge epithelium) thickness measured and the mitotic figures counted after routine processing and H·E stain. All the palates were photographed, and the number of rugae & the rugal pattern analysed. TEM photographs of MEE cells were observed after routine processing. The results were as follows ; 1. Rat fetus body weight after retinoic acid treatment increased significantly compared with the control group. 2. Mitotic figures in the retinoic acid treated group increased significantly compared with control group. 3. In the retinoic acid treated group, 79.3% of fetuses had cleft palates. Among fetuses with cleft palates, complete cleft palates were 10.6%, incomplete cleft palate 89.4%. Incomplete clefts were of two types ; median type (cleft palate at the intermolar region) and soft palate type (cleft posterior to the 8th rugae). Median type was 64.6% and the soft palate type 35.4%. 4. 2.3% of the fetuses had the numerical anomaly of the palatal rugae in the control group, but that of retinoic acid treated group 87.7%. 5. 17.4% of palatal rugae of the control group was disrupted, but 100% of the retinoic acid treated group disrupted. 6. Rugal papillae were observed in the 15.1% of fetuses of the control group and 63.1% of fetuses of the retinoic acid treated group. 7. Longitudinal rugae were observed in 19% of fetuses of the retinoic acid treated group, but not in the control group. 8. In TEM photographs, cytoplasmic processes, intercellular space, and desmosomes decreased. Swelling of mitochondria & ER were also found in the retinoic acid treated groups. According to the above results, it appears that there is close relationship between palatal rugae and cleft palates, and that excess retinoic acid induces disruption of pattern and numerical variations of rat fetus palate rugae. Also retinoic acid has an inhibitory effect on the proliferation of medial edge epithelial cells of palatal shelves. The cleft palates may be induced by the above mentioned retinoic acid effects. But, the exact mechanisms of retinoic acid on cleft palate formation is not thoroughly known and should be further studied.

Descending Necrotizing Mediastinitis (DNM) is a complication of oropharyngeal infections that can spread to the mediastinum. It is difficult to diagnose early because clinical and radiologic findings appear in the late stage of the infection. late diagnosis is the principal reason for the high mortality in DNM. An 18-year-old female admitted with Ludwig's angina from dental caries. Despite of combined antibiotics, dental extraction and drainge of submental abscess, infection spread to the cervical area. Chest computed tomogram revealed extension of the abscess to the pretracheal and periaortic space and development of bilateral pleural empyema. We performed bilateral cervical mediastinotomy and thoracotomy for drainage and debridement. Tracheostomy to secure the airway and postoperative pleural irrigation were performed. Postoperative course was uneventful and patient was discharged on the 40th postoperative day. It is important to perform chest CT scanning for early diagnosis of DNM when oropharyngeal infection spreads to the cervical area. Improved survival of patients with DNM implies early and radical surgical drainage and debridement via a cervical mediastinomy and thoracotomy.

BACKGROUND: With the recent development in arterial reconstructive procedure such as percutaneous transluminal coronary angioplasty or atherectomy, the incidence of vascular complications involving femoral artery is increasing due to greater use of larger percutaneous instruments(including arterial sheath) and periprocedural anticoagulant therapy. Femoral pseudoaneurysm requires rapid diagnosis and management to prevent limb ischemia, worsening of the arterial injury or repair of the arterial defect. Recently, accurate diagnosis of these injuries can be made nonivasively with duplex sonography and Doppler color flow imaging, and nonsurgical treatment may be possible by using external compression guided by ultrasound even in patients requiring prolonged anticoagulant therapy. METHOD: Three patients, one undergoing coronary angiography and two undergoing percutaneous transluminal coronary angioplasty, developed expansile groin masses at the vascular access sites diagnosed as femoral artery pseudoaneurysm s by Doppler ultrasound. All patients were hypertensives, taking aspirin and two patients who underwent PTCA received intravenous heparin after procedure. After diagnosis of femoral pseudoaneurysm, all patients underwent mechanical(C-clamp) external compression guided by ultrasound for 3 hours. RESULT: Follow up color flow scans were obtained after 24 hours and in one patients, blood flow in the tract was eliminated but persistent blood flow was observed in two patients who underwent PTCA. Before closure of pseudoaneurysm, one patient needed another 6 hours of ultrasound guided compression and the other needed more 12 hours. All patients were discharged without complication or recurrence of pseudoaneurysm. CONCLUSION: These cases suggest that nonsurgical closure of femoral pseudoaneurysms is feasible even in patients requiring prolonged antiplatelet and anticoagulant therapy.

The authors attempted to examine the allelic association between the A1 allele of Dopamine D2 receptor and schizophrenia, alcoholism, drug addiction in Koreans. Schizophrenic patients(n=31), alcoholism(n=65), drug addiction(n=18) and controls(n=52) were examined by case-control study for distribution of the Taql polymorphism of the dopamine D2 receptor gene in Korean population to minimize the effect of racial differencies in gene frequencies. In schizophrenics, the numbers of schizophrenics with A1A1, A1A2, A2A2 were 9(29%), 15(48%) and 7(22%) respectively and in alcoholics with A1A1, A1A2, A2A2 were 14(21.5%), 36(55.4%) and 15(23.1%) respectively and in drug addiction with A1A1, A1A2, A2A2 were 4(7.6%), 24(46.2%) and 24(46.2%) respectively. The prevalence of the A1 allele in schizophrenics, alcoholics, drug addiction and controls were 77%, 76.9%, 67% and 53.8% respectively. And the frequency of the A1 allele in schizophrenics, alcoholics, drug addiction, and controls were 0.53 0.49, 0.39 and 0.31 respectively. There was significant difference in the frequency of the A1 allele between schizophrenics, alcoholics and controls. We also classified our alcoholic population. For classification by severity, we used the median MAST score 30 in our samples. There was also significant difference in the frequency of the A1 allele between less severe group(0.42) and more severe group(0.57). This data suggest that the A1 allele is associated with schizophrenia and alcoholism in Korean. Furthermore the prevalence of the A1 allele increased in more severely affected alcoholics. The authors conclude that our data support an allelic association between the A1 allele at dopamine D2 receptor and schizophrenia, alcoholism. These results suggest the A1 allele of the DRD2 gene is associated with a number of behavior disorders in which it may act as a modifying gene rather than as the primary etiological agent.

OBJECTIVE: This study was aimed to investigate of newborn babies sex ratio in Seoul Seong Ae hospital and review of future problem. METHODS: We reviewed retrospectively the 21,332 cases of deliveries in women visiting at Seoul Seong Ae hospital from Jannuary 1994 to December 2003 (10 year's period). We investigated 1st baby and 2nd baby sex ratio and in case of 3rd baby, subdividing then into tree groups (first and second are female, first and second are male, first and second are male and female). We arranged the data at the base of childbirth registers and patients' obligation records. RESULTS: The results were as follows, 1. The total sex ratio in last 10 years was 111.2:100 (male:female). 2. 1st baby sex ratio was 109.2:100. 3. 2nd baby sex ratio was 110.6:100. 4. 3rd baby sex ratio was 133:100. CONCLUSION: These findings suggest that unbalance of sex ratio in 3rd baby is extremely serious trend in this country and is expected a tremendous social problems in early 21th century.

PURPOSE: The most important step for patients who come to the emergency department with ureter stones is acute pain management. There have been insufficient studies on what factors affect acute pain management for ureteral colic the most. In this study, patients with ureteral colic were divided into two groups: one group, in which the pain was first managed with an analgesic, and another group with unmanaged pain, to find factors that most affect additive analgesics administration for ureter stones. METHODS: There were 121 patients, eventually confirmed for the presence of ureter stones through a computed tomography CT scan, included in this study. When ureter stones were suspected after the initial patient evaluation, initial pain was assessed through numerical rating scale (NRS) and the first analgesic was administered once. Pain was reassessed through NRS after 30 minutes. At that time, if the pain was managed, the patient was assigned to Group 1. If the pain persisted, another analgesic was administered for the second and third time, and the patient was assigned to Group 2. Finally, ureter stones were identified through CT scan. RESULTS: There were 58 patients (47.9%) in Group 1 and 63 patients (52.1%) in Group 2. There were no statistically significant differences in average age, serum creatinine, size of ureter stone, and severity of hematuria between the two groups. The differences in NRS measured initially and after 30 minutes were statistically significant (7.6+/-1.4 vs. 8.6+/-1.2, p<0.001; 1.4+/-1.3 vs. 6.6+/-1.9, p<0.001, respectively). The presence of hydronephrosis and perirenal edema were also statistically significant (p<0.001, p=0.007). The affecting factor for the administration of additive analgesics was hydronephrosis (odds ratio 7.213, p<0.001). CONCLUSION: Hydronephrosis is an important factor in the treatment of patients with additive analgesics. It can also be used as a predictive index to assess the severity of pain in patients with ureter stones.

PURPOSE: To determine the accuracy of automated computer aided volumetry for simulated small pulmonary nodules at computed tomography using various types of phantoms MATERIALS AND METHODS: Three sets of synthetic nodules (small, calcified and those adjacent to vessels) were studied. The volume of the nodules in each set was already known, and using multi-slice CT, volumetric data for each nodule was acquired from the three-dimensional reconstructed image. The volume was calculated by applying three different threshold values using Rapidia(R) software (3D-Med, Seoul, Korea). RESULTS: Relative errors in the measured volume of synthetic pulmonary nodules were 17.3, 2.9, and 11.5% at -200, -400, and -600 HU, respectively, and there was good correlation between true volume and measured volume at -400 HU (r=0.96, p<0.001). For calcified nodules, relative errors in measured volume were 10.9, 5.3, and 16.5% at -200, -400, and -600 HU, respectively, and there was good correlation between true volume and measured volume at -400 HU (r=1.03, p<0.001). In cases involving synthetic nodules adjacent to vessels, relative errors were 4.6, 16.3, and 31.2 % at -200, -400, and -600 HU, respectively. There was good correlation between true volume and measured volume at -200 HU (r=1.1, p<0.001). CONCLUSION: Using computer-aided volumetry, the measured volumes of synthetic nodules correlated closely with their true volume. Measured volumes were the same at each threshold level, regardless of window setting.
