BACKGROUND: Surgical correction of the full spectrum of esophageal atresia with tracheoesophageal fistula has improved over the years, but the mortality and morbidity assoiated with repair of these anomalies still remains high. MATERIAL AND METHOD: We retrospectively analyzes 27 surgically treated patients with esophageal atresia and tracheoesophageal fistula at Dong-A University Hospital between January 1992 and March 1997. RESULT: There were 21 male and 6 female patients. Mean birth weight was 2.62+/-.385 kg(2.0~3.4 kg). Twenty- four(88.9%) had esophageal atresia with distal tracheoesophageal fistula, and 3(11.1%) had pure esophageal atresia. Four(14.8%) infants were allocated to Waterston risk group A, 18(66.7%) to group B, and 5(18.5%) to group C. In eighteen(66.7%) infants with associated anomalies, cardiovascular anomalies were the most common. Three had a gap length of 3.5 cm or greater(ultra-long gap) between esophageal segments, 7 had 2.0 to 3.5 cm(long gap), 8 had 1.0 to 2.0 cm(medium gap), and 9 had 1 cm or less(short gap) gap length. Among 27 neonates, 3 cases underwent staged operation, late colon interposition was done in 2, and all other 24 cases underwent primary esophageal anastomosis. Oerative mortality was 2/27(7.4%). Causes of death included acute renal failure(n=1), empyema from anastomotic leak(n=1), necrotizing enterocolitis(n=1), sepsis(n=1), insulin-dependent diabetus mellitus(n=1 . There were 4 anastomosis- related complications including stricture in 3, leakage in 1. Mortality was related to the gap length(p<.05). CONCLUSION: Although the complication rate associated with surgical repair of these anomalies is high, this does not always implicate the operative mortality. The overall survival can be improved by effective treatment for combined anomalies and intensive postoperatve care.

Most of dural arteriovenous malformations(AVM's) of lateral and sigmoid sinuses are known to acquired lesions evolving from a previously thrombosed dural sinus. Their clinical symptoms and signs are variable and their natural history is usually that of gradual progression and hence surgery is frequent necessary. The preferred surgical treatment is complete isolation or excision of the lesion. The authors have experienced 1 case of AVM's of lateral and sigmoid dural sinuses associated with intracerebral hematoma which was treated with complete excision of involved sinus with good result.

Psoriatic arthritis is a rare inflammatory joint disease associated with radiographic evidence of periarticular bone erosion and sometimes frank joints destruction among psoriatic patients. There have been only a few reports of atlantoaxial subluxation in patients with psoriatic arthritis in the world. The authors report a case of psoriatic arthritis with atlantoaxial subluxation. This 27-year-old man with a three year history of psoriatic skin lesion presented with painful limitation of neck and multiple joint deformities of the hands and feet, etc. We performed combined interspinous and Gallie fusion for the atlantoaxial subluxation and obtained good results of immediate and long term postoperative stability with Philadelphia neck collar only after this procedure.

BACKGROUND/AIMS: Hepatocytes on the hepatic lobule mipate from portal zone to centrilobular mea as the DNA synthesis within it. And also, the xenobiotic reactions reveal characteristic differences associated with zone specific metabolism in the liver acinus. In this study, the zonal distribution of ethylnitrosourea (ENU)-induced hepatic precancerous lesion was stereologically investigated. METHODS: Nine B6C3F1 mices were given I.p. injection of ENU (60 ug/pn body weight) when the pups were 15 days old prior to sacrifices at 8 weeks of life. All the 150 consecutive sections, 3 p m in thickness, were stained with hematoxylin and eosin and identified the basophilic precancerous lesions with 80-165 p m diameter in equatorial plane by the Zeiss microprojector. And then the distances from the center of selected foci to terminal hepatic vein or portal vein branches were estimated under the microscopic fields. As a control group, the same estimations were performed from the random points by the appointments of random digit table. RESULTS: Mean distance between ENU-induced 52 hepatocellular foci and the nearest terminal hepytic vein was 181.15+112.39 p m (Mean+ SD), but that of randomly selected 104 points was 291.73+157.98pm (Mean+5D) (Students t-test, p<0.0005). Substantially, 52.7% of ENU-induced 52 hepatocellular foci were within 300 p m from the terminal hepatic vein, but randomly selected 104 points were only 50.9% (Shapiro Wilk W test, w=0.819857, p=0.048038). Mean distance from ENU-induced 52 foci to portal vein was 398.85+149.98pm (Mean+SD), but that from the randomly selected 104 points was 315.87+145.79 pm (Mean+SD)(Students t-test, p<0.0005). CONCLUSION: Stereologically, ENU-induced mice liver cell foci distribute non-randomly to Zone III, centrilobular zone of mouse hepatic acini where promote invasion toward terminal hepatic veins.

PURPOSE: We conducted this study in order to determine clinical features and prognostic factors in adults with acute tetrodotoxin (TTX) poisoning caused by ingestion of puffer fish. METHODS: In this retrospective study, 107 patients were diagnosed with TTX poisoning. The subjects were divided into two groups according to duration of treatment; Group I, patients were discharged within 48 hours (n=76, 71.0%), Group II patients were discharged after more than 48 hours (n=31, 29.0%). Group II was subsequently divided into two subgroups [IIa (n=12, 11.2%), IIb (n=19, 17.8%)] according to the need for mechanical ventilation support. RESULTS: In multivariable logistic regression analysis, the predictors of the need for treatment over 48 hours were dizziness (odds ratio [OR], 4.72; 95% confidence intervals [CI], 1.59-12.83), time interval between onset of symptom and ingestion (OR, 0.56; 95% CI, 0.16-0.97), PaCO2<35 mmHg (OR, 8.37; 95% CI, 2.37-23.59). In addition, predictors of the need for mechanical ventilation were a time interval between onset of symptoms and ingestion (OR, 0.54; 95% CI, 0.11-0.96) and PaCO2<35 mmHg (OR, 5.65; 95% CI, 1.96-18.66). CONCLUSION: Overall, dizziness, time interval between onset of symptoms and ingestion, DeltaDBP and PaCO2<35 mmHg predict the need for treatment over 48 hours, time interval between onset of symptoms and ingestion and PaCO2<35 mmHg predict the need for mechanical ventilation support after acute TTX poisoning.

BACKGROUND AND OBJECTIVES: Many studies have established risk factors for cardiovascular diseases. The Duke treadmill score has gained widespread acceptance for prognosis and diagnosis in cardiac diseases. Recently, changes in heart rate during and after exercise have also been studied to predict the prognosis of cardiac diseases. We examined the relationship between the incidence of cardiovascular events and exercise capacity, achievement of 85% maximal predicted heart rate (MPHR) or heart rate recovery (HRR) after a routine exercise treadmill test. SUBJECTS AND METHODS: We studied 88 patients with chest pain who were over the age of 30. They were referred for exercise treadmill test for assessment of chest pain and underwent symptom-limited, exercise test with a cool down period of 30 seconds. HRR was defined as the difference in heart rate between peak exercise and 1 minute after exercise. Delta heart rate (DHR) was defined as the difference in heart rate between resting and peak exercise. Other parameters in the exercise test were also measured. RESULTS: Cardiovascular events were found in 13 of the 88 patients. In the events group, age, peak heart rate in exercise, ST depression, maximal exercise capacity, HRR, DHR and achievement of 85% MPHR were all significant variables. There was a favorable prognosis in the patients with a value of HRR >22 beats/minute and a value of DHR >83 beats/minute. Even after adjusting for age, sex, ST depression and left ventricular hypertrophy, the parameters of maximal exercise capacity, HRR, DHR, and achievement of 85% MPHR remained predictive prognostic factors in cardiovascular events. CONCLUSION: Parameters in exercise treadmill test, such as maximal exercise capacity, HRR, DHR and achievement of 85% MPHR, appear to provide additional information and are important variables associated with the prediction of risk in cardiac events.

Congenital agenesis, aplasia or hypoplasia of the internal carotid artery is rare vascular disease and usually combine with intracranial aneurysm, subarachnoid hemorrhage, or intracerebral hemorrhage. We report a case of bilateral congenital hypoplasia of internal carotid artery in a 36 year-old woman presented with semicomatose mentality. The brain computed tomography(CT) revealed intracerebral hemorrhage with intraventricular hemorrhage, and cerebral angiography showed hypoplasia of bilateral internal carotid artery without narrowing of the bony carotid canal on the temporal bone CT.

In our comparative study of L1 consensus primers with E6 type-specific primers for detection of human papillomavirus (HPVs) by polymerase chain reaction (PCR) in 35 cases of cervical neoplasia, the detection rate by E6 primers (54%; 19/35) was significantly higher than that by L1 primers (25%; 9/35) (p < 0.01). And all specimens HPV-positive with L1 primers were also positive by E6 primers. HPV DNA could be amplified in 36% (9 of 25) of tissue by L1 consensus primers from which beta-globin gene was amplified as compared with 64% (16 of 25) of tissue by E6 type-specific primers. With the L1 consensus primers, 8 cases were positive for HPV-16 and 1 case was positive for HPV-33. These results show that the L1 consensus primers have inferior sensitivity to the E6 type-specific primers for the detection of HPV by PCR. But the L1 consensus primers have great value in making simultaneous detection of various HPV types in a single tube reaction, thus they permit reduction of time and the economic burden of the experiment.
