OBJECTIVE: To analyze the tubal patency in the young-aged women underwent diagnostic laparoscopy with Fitz-High-Curtis Syndrome (FHCS). METHODS: Clinicopathologic results of young-aged women who underwent diagnostic laparoscopy with pelvic inflammatory disease from March 2005 through April 2007 were reviewed. Twenty six patients aged 19-29 years old and preserved their both tubes after diagnostic laparoscopy were included in this study. All were underwent chromopertubation test (CPT) during laparoscopy and postoperative hysterosalpingography (HSG) 3 months later. RESULTS: Of 26 patients, eight patients were diagnosed with FHCS and the others were not. There was no significant difference in mean age, mean hospitalization days, and frequency in past-history of parturition, abortion, chlamydia and gonococci infection between patients with FHCS and with non-FHCS (P>0.05). There was no significant difference in frequency of tubal obstruction in laparoscopic CPT (P>0.05) but not in postoperative outpatient HSG (P<0.05). CONCLUSION: The tubal obstruction may be more frequent in FHCS than non-FHCS and the reliability of laparoscopic CPT for diagnosing the tubal obstruction is supposed to be low. Therefore, as for FHCS patients, HSG should be executed to investigate tubal factor which is helpful to forecast the fertility.

A theoretical study advocated for alleviating the worker's responsibility of burden of proof to establish the causality of an occupational disease, since such a responsibility is unfair to the worker. The recent judgment has adopted some of these arguments for alleviating the worker's responsibility of burden of proof, and the judgment is significant since it is the first Supreme Court decision to recognize the causality of occupational diseases. The judgment expressly confirms that it is more proactive to recognize the causal relationship between work and certain diseases, and to provide compensation for industrial accidents to employees who are exposed to harmful substances at all times. In addition, the judgment also confirms that coverage of industrial safety and health risks is in accordance with the original purpose and function of the industrial accident insurance system, which aims to share risks through public insurance.

Postrenal segment anomalies of inferior vena cava such as bilateral inferior vena cava and left-sided inferiorvena cava can simulate lymphadenopathy on CT scan and these anomalous veins need consideration in retroperitonealoperations such as procedures for prevenetion of venous embolism, splenorenal shunt operation and aorticprosthetic repalcement. Retrocaval ureter is a rare cause of obstructive uropathy or medical deviation of ureter.We analysed 16 cases of postrenal segment anomalies daignosed by CT, vena cavography, retrograde pyelography andultrasonography including six rare positional anomalies at hepatic segment of inferior vena cava diagnosed bycardiac angiography. The results were as follows. 1. Postrenal segment anomalies were 6 cases of bilateral IVC, 8cases of left-sided IVC and 2 cases of retrocaval ureters. On CT scan, 3 cases of bilateral IVC and 4 cases ofleft-sided IVC were accompained by malignant tumors, but caval veins could be discriminated from enlarged nodesbecause of continuous tubular nature of vein on consecutive sections with homogeneous strong enhancement. Twocases of retrocaval ureters showed hydroureteronephrosis due to ureteral compression by IVC. 2. Hepatic segmentanomalies were 6 cases. Five cases of IVC on left side of vertebral crossed midline at live to enter right-sidedright atrium and one case of IVC on right side crossed midline to enter left-sided right atrium. Four cases ofcomplex cardiac anomalies, 4 cases of asplenia and 2 cases of situs ambigus were associates with these anomalies.

PURPOSE: To assess the CT findings of bronchial anthracofibrosis with or without active tuberculosis. MATERIALS AND METHODS: Analysis of the CT scans of 35 patients with bronchoscopically proven anthracofibrosis revealed that 25 were negative for active tuberculosis and ten were positive. Bronchial and pleural lesions, pulmonary parenchymal lesions, and mediastinal/hilar lymph nodes were retrospectively evaluated. RESULTS: Common radiologic findings of anthracofibrosis included diffuse bronchial narrowing (50%), wall thickening (37%), and mass-like soft tissue density in central bronchi (8%). The right middle lobe was most commonly involved (31%). Common findings of pulmonary parenchymal lesions included consolidation (37%), atelectasis (31%), and ground-glass opacity (10%). These bronchial or pulmonary parenchymal findings were common in patients with or without active tuberculosis. Findings of multiple poorly defined small nodules, including branching opacities and consolidation with internal low density were seen only in patients with active tuberculosis (p<0.01), while enlarged mediastinal or hilar lymph nodes were frequently observed in patients with or without active tuberculosis. Necrotic lymph nodes were present only in those with active tuberculosis (p<0.05). CONCLUSION: When CT scans depict central bronchial narrowing, wall thickening, or mass-like soft tissue density with atelectasis or consolidation, especially in older patients without a distinct central lung mass lesion, anthacofibrosis should be included in the differeatial diagnosis. When multiple poorly defined small nodules, including branching opacities, consolidation with internal low density or necrotic lymph nodes are observed, the possibility of concomitant active tuberculosis should be considered.

PURPOSE: To report the findings of a six-year medial oudit performed at our mammographic screening centre, comparing those findings with the follow-up data stored at our hospital and at the Korea Central Cancer Registry. MATERIALS AND METHODS: We analyzed the findings of 32,289 mammographic examinations of 25,541 women performed at our screening center between 1994 and 1999. For follow-up and outcome monitoring, the guideline of the American College of Radiology Breast Imaging Reporting and Data System (ACR BI-RADS) was used. All mammograms were categorized by means of BI-RADS, and cases in categories 0, 4, and 5 were followed up through a review of our hospital information system. To determine whether any cases were false negative, we compared breast cancer patients registered in our medical record department and in the Korean Central Cancer Registry during the study period, with women whose mammograms were interpreted as normal or benign at our screening center within a year prior to cancer diagnosis. RESULTS: The mean age of women enrolled in this study was 48.6 years, ten years less than reported in the West. The recall rate was 6.2%. Among 256 women whose final assessment category was 4 or 5, breast cancer was diagnosed in 51. The cancer detection rate was 2.0/1,000 women; positive predictive value 1 (PPV1: PPV, based on abnormal findings at screening examination) was 2.5% of cases and PPV2 (PPV when biopsy or surgical consultation was recommended) was 20%. The most common mammographic finding was microcalcifications only (45%). The rate of minimal breast cancer, including invasive cancer less than 1 cm in diameter and ductal carcinoma in situ, was 72.5%. Node positivity was 27%. Sensitivity was 85.0% based on the tumor registry of our institution's medical record department, and 78.5% based on the tumor registry of the Korea Central Cancer Registry. Specificity was 99.0%. CONCLUSION: In our study, the cancer detection rate at screening mammography was 2.0/1,000 women. The rate of minimal breast cancer (72.5%) was very high but measurable sensitivity was 78.5%, somewhat lower than the ACR guideline of 85%. To improve the performance of screening mammography, appropriate interpretation of mammography and constant, follow-up and outcome monitoring are important.

PURPOSE: This study was undertaken to evaluate the factors correlated with the clinical course and outcome in patients of Henoch-Schnlein Purpura. METHODS: The medical records of 104 children diagnosed with Henoch-Schnlein Purpura (HSP) from January 1996 to April 2006 were reviewed retrospectively. The patients were divided into two groups: patients with Gastrointestinal (GI) symptoms and those without GI symptoms. When there were joint, scrotum, and renal symptoms except for skin lesion in whole HSP, those patients were excluded. The history of acute infection, duration of admission, treatment requirement, recurrence of HSP, CBC, stool occult blood test, abdominal ultrasonographic findings and GI endoscopic findings were reviewed. RESULTS: Among 104 patients, patients with GI symptoms included 66 cases (63.5%), those without GI symptoms accounted for 38 cases (36.5%). GI symptoms included: abdominal pain in 57 cases (54.8%), vomiting 21 cases (20.2%), GI bleeding 5 cases (4.8%), nausea 3 cases (2.9%) and diarrhea 3 case (2.9%). Positive GI symptoms and GI mucosal lesions on GI endoscopy had a statistically significant correlation with increased admission duration, treatment requirement, recurrence of HSP, and positive stool occult blood. Six cases with small intestinal wall thickening were noted on abdominal ultrasonography. Six cases of hemorrhagic gastritis and hemorrhagic duodenitis, 3 cases of duodenal ulcer, 3 cases of hemorrhagic gastritis and duodenal ulcer, 2 cases of hemorrhagic duodenitis and colitis, and 1 case of colitis were noted on GI endoscopy. CONCLUSION: These results suggest that GI endoscopic examination may be helpful for the diagnosis and treatment of children with HSP.
