In evaluating the esophago-gastric junction, many difficulties are well known in a single contrast study, andit may often be resolved with double contrast technique. By double contrast technique, the special en face viewfor the esophago-gastric junction was obtained in 298 cases at Inje Medical College Paik Hospital from Jan. 1981 to June 1981. Five basic patterns were recognized and classifed from type I to V. Their incidences were obtained.-type I ; 18%, type II; 50%, type III; 23% type IV ; 7%, type V; 2%. The most common position of patients is left lateral, and zero degree is the most common at elevation of fluoroscopic table. Type III is the most common typeof the esophage-gastric junction in inspiration, and type I expiration. Any significant deviations from thesenormal geometry of the esophago-gastric junction as displayed by double contrast study, indicate an abnormality.More special attentions are required to evaluate a minute pathologic condition of the esophago-gastric junction.

PURPOSE: Persistent pulmonary hypertension (PPHN) of the newborn has been treated with some vasodilators including tolazoline. But these drugs have many side effects, especially systemic hypotension . To investigate the usefulness of the nitroglycerin as a specific vasodilator with few side effects, this study was done. METHODS: Nitroglycerin was administered within 1st one day after birth in 8 newborn infants who were diagnosed as PPHN by echocardiography. They were born at Il Sin hospital from March 1994 to March 1996. Nitroglycerin was started as 2microgram/kg/min and its maximum dose was 6microgram/kg/min. Muscle relaxants and inotropic drugs were used together in all cases. Arterial blood gas analysis, systemic blood pressure, heart rate, renal function and electrolyte were checked in all patients. Alveolar-arterial oxygen difference (AaDO2) and oxygenation index (OI) were measured. RESULTS: 6 cases (75%) survived but 2 cases expired due to air leak.1) Basal mean AaDO2 was 631.4+/-21.7mmHg. It decreased to 493.9+/-1453.1 mmHg at 10hr after loading infusion and to 373.6+/-217.7mmHg at 48hr (P<0.05). 2) Basal mean OI was 35.1+/-15.7 and it decreased significantly to 12.6+/-14.8 (P<0.05) at 10hr. 3) There was no significant hypotension in systolic, diastolic and mean blood pressure during treatment of nitroglycerin. 4) There was no significant change in renal function, serum electrolyte and heart rate during treatment of nitroglycerin. CONCLUSIONS: Nitroglycerin produced systemic venodilatation and pulmonary arterial dilatation at the dose that produce only minimal systemic arterial dilatation. Nitroglycerin is an effective and safe drug in the treatment of PPHN.

Primary malignant lymphoma of the appendix is an unconnnon neoplasm although the gastrointestinal tract is the most common extranodal site of malignant lymphoma. We report a case of primary malignant lymphoma of the appendix in a 54-year-old male, who presented with pain in the right lower abdomen. An appendectomy was performed. The appendix measured 9.5 cm in length and 5.5 cm in diameter. Cut sections showed a solitary circumferential mass in the appendiceal lumen. Light microscopic features were compatible with malignant lymphoma of diffuse large cell type(Working Formulation) and the immunophenotype was B cell type.

Tethered cord syndrome is one of the spinal dysraphism with low-lying conus medullaris frequently associated with spinal lipoma, diastematomyelia and thick filum. The clinical manifestation is variable from no overt symptoms for a long time to back pain, scoliosis, progressive neurological deficit of legs and incontinence. Therefore the diagnosis requires a strong clinical suspicion and aggressive investigation. We experienced a case of 1 day-old male infant who was presented with small soft mass on sacral area. Spinal ultrasonography and spine MRI revealed tethered cord associated with intradural lipoma. We reported a case of tethered cord syndrome with brief review of literatures.

PURPOSE: The purpose of this study was to identify the relationships among distress from drinking, alcohol abstinence self-efficacy and outcome expectancy in youths. METHOD: The participants in this study were 174 university students who were enrolled by convenience sampling. The data were collected from March to August, 2005. Descriptive statistics and Pearson's correlation coefficients with SPSS 12.0 were used to analyze the data. RESULTS: There were significant differences in the physical distress from drinking according to gender, age, residence, drinking frequency and drinking capacity. There were significant differences in alcohol abstinence self-efficacy by drinking frequency and drinking capacity. There were significant differences in drinking outcome expectancy according to gender, drinking frequency and drinking capacity. The physical distress from drinking showed a significant positive correlation with alcohol abstinence self-efficacy (r=.312, p=.000) and negative correlation with drinking outcome expectancy (r=-.353, p=.000). Alcohol abstinence self-efficacy showed a significant negative correlation with drinking outcome expectancy (r=-.387, p=.000). CONCLUSION: There were relationships among physical distress from drinking, alcohol abstinence self-efficacy, and drinking outcome expectancy. These findings provide the basis to prevent problems of drinking by developing alcohol control program for university students.

PURPOSE: To evaluate the relationship between radiographic findings after surfactant replacement therapy and prognosis in newborns with respiratory distress syndrome (RDS). MATERIALS AND METHODS: The chest radiographs and medical records of 78 infants [body weight 840-3600g, mean 1682g, gestational age 20 -38 (mean, 31) weeks] who had been treated with surfactant were retrospectively analysed. Surfactant was applied 1 -12 (mean, 5) hours after birth. By comparing pre-and post-surfactant radiographs, radiographi changes were graded as either uniform bilateral improvement (grade 1), asymmetrical unilateral improvement (grade 2), or no improvement (grade 3). Complications such as barotrauma, bilateral diffuse consolidation, or intracranial hemorrhage were tabulated. We correlated the prognosis with (a) the radiographic improvement pattern, (b) the time of surfactant application, and (c) the incidence of pulmonary complications, respectively. RESULTS: Forty-six (59%) of 78 infants survived, and 32 (41%) died. The survivors comprised 38 infants in group 1 (67%, n=57), six in group 2 (46%, n=13), and two in group 3 (25%, n=8) (p < 0.05). The survival rate did not correlate with the time of surfactant application (p> 0.05). Infants with barotrauma had a lower survival rate (42%, 10/24) than those not suffering from this condition (67%, 36/54) (p<0.05). The condition oc-curred in 12 (21%) of 57 infants in group 1, six (46%) of 13 in group 2, and six (75%) of eight in group 3 (p <0.05). Eleven(92%) of 12 infants with pulmonary hemorrhage, seven (100%) of seven with intracranial hemorrhage above grade 3, and seven (41%) of 17 with sepsis died. CONCLUSION: The radiographic changes occurring after surfactant replacement therapy correlated closely with the incidence of barotrauma and the prognosis of newborns with respiratory distress syndrome. Close observation of follow-up radiographic findings plays an important role in therapy and prognosis.

BACKGROUND: Both the Natural killer/T-cell lymphoma (NKTL) and the peripheral T-cell lymphoma (PTCL) are relatively prevalent in the Asian population, and they are strongly associated with the Epstein-Barr virus (EBV). These two diseases have several common pathologic features, but show somewhat different clinical presentations. The critical point in terms of differentiating of these disease groups might be the impact of EBV in pathogenesis, and the variable gene expression of EBV regulated by a major latent C promoter (Cp). METHODS: We investigated 43 cases of NKTL and 30 cases of PTCL to evaluate EBV associated characteristics. EBV in situ hybridization was performed in all of the submitted cases. In the EBV positive cases, the methylation status of Cp which drives the expression of immunodominant viral nuclear protein, was examined by sensitive methylation specific PCR using paraffin embedded tissue. RESULTS: EBV was found in 70% (30/43) of NKTL and 43% (13/30) of PTCL. Nasal and gastrointestinal lymphomas were predominantly NKTL. All of the successfully amplified cases of EBV positive NKTL and PTCL were of methylated Cp status. CONCLUSIONS: The detection rate of EBV is high in NKTL, especially in the nasal area. The constantly methylated EBV Cp reflects the major role of Cp in regulating the EBV latency pattern and in helping EBV to avoid host immune system in both NKTL and PTCL.

Leiomyoma is the most common benign tumor of the esophagus, but it still occurs rarely as compared with the incidence of carcinoma in this area. Most of leiomyomas may manifest itself with unusual and inconsistent symptoms, and found incidentally during endoscopic or radiographic examination. Those who menifested symptoms are included as dysphagia and vague pain mostly. We experienced recently two cases with esophageal leiomyoma who underwent successful surgical resection and endoscopic enucleation, respectively.
