Hydrogen peroxide is a commonly used oxidizing agent. If injected, it may result in morbidity via direct caustic injury, oxygen gas formation, and lipid peroxidation. We report a 40-year-old male patient who accidentally swallowed undiluted hydrogen peroxide (35%). The initial chest computed tomography scan showed no active lesions. He was admitted to the intensive care unit for conservative treatment. Fourteen days after treatment, uncontrolled fever and foul oder sputum occurred, which was not alleviated despite empirical antibiotics therapy. Findings on a chest computed tomography showed tracheo-esophageal fistula at the lower trachea and left main bronchus. He underwent surgical replacement surgery and was discharged without complication after 52 days of admission.

Forty five patients with inferior vena cava (IVC) thrombosis were studied with the use of ultrasonography (US) and computed tomography (CT). Thirty seven cases were cased by tumor extension and the primary neoplasms were hepatocellular Ca. (26cases), renal cell Ca. (6 cases), Wilms' tumor (1 case), IVC leiomyosarcoma (1 case) and retroperitoneal metastatic tumor (3 cases). Non-tumor thrombus were 8 cases which included 5 cases of Budd-Chiari syndrome and 3 cases of thrombophlebitis. US and CT both were good for the diagnosis of IVC thrombosis. Cranial extension was better demonstrated by US whereas CT yielded better delineation of the lower extension. Even though, differentiation of tumor non-tumor thrombi by the echogenecity and density of the thrombus was not possible, the finkdings of adjacent tumor mass, complete obstructive thrombus within dilated lumen with bulging wall, and nontapered acute margin of thrombus made the possibility of tumor thrombus more likely.

The incidence of pancreatic trauma is increasing and still remains a major source of morbidity and mortality. We have graded the pancreatic trauma on CT according to its pattern into four grades. We also determine the accuracy of CT in the evaluation of pancreatic trauma and the role of CT for delineation of pancretic ductal injury which is critical factor in outcome of pancreatic trauma. CT correctly diagnosed the pancreatic trauma and its traumatic pattern and severity in 22 of 25 cases. Pancreatic enlargement was the most common findings observed in 19 cases. Other findings were 15 cases of intrapancreatic low density hematoma, 12 cases of parenchymal fracture which were predilected in pancreatic neck area. CT grade III and IV could predict the pancreatic ductal injury, and was well correlated with severity of posttraumatic pancreatitis, duration of admission days and incidence of complications. So we concluded that CT can play a definite role for diagnosing and determining the prognosis of pancreatic trauma.

Diffuse interstitial lung disease(DILD) is a large group of heterogeneous diseases that diffusely involve the pulmonary connective tissues, principally subpleural, interlobular and alveolar wall portions. Terminology and classification of these diseases are not uniform, and the cause and the pathogenesis are unknown in many entities. It is generally accepted that the response to therapy is related to the relative degree of cellularity and fibrosis present, therefore a histologic evaluation of the relative extent and severity of these changes is required. We reviewed 52 cases of DILD from January 1990 to May 1995 diagnosed by open lung biopsy to reappraise classification and quantitative assessment of the histopathologic features. Differential histopathologic features between usual interstitial pneumonia(UIP) and nonspecific interstitial pneumonia(NIP) were examined with a correlation of HRCT findings and clinical findings. Among 52 cases of DILD, 18 cases(34.6%) were UIP, 6 cases(11.5%) were hypersensitivity pneumonia was NIP was 5 cases(9.6%), interstitial lung diseases associated with the connective tissue diseases were 5 cases(9.6%), inorganic dusts were 4 cases(7.7%), infections were 4 cases(7.7%), durgs were 2 cases(3.8%), acute interstitial pneumonia was 1 case(1.9%), sarcoidosis was 1 case(1.9%) in order of frequency plus 6 other cases(11.5%). UIP was the most frequent DILD in this study which seemed to be a criteria bias of patient selection on open lung biopsy. Quantitative assessment of histopathologic features was useful in the differential diagnosis of DILD and differentiation of UIP from NIP was possible based on histopathologic features and supported by HRCT. UIP disclosed a significantly high score of fibrotic changes, especially in the interstitial fibrosis, smooth muscle proliferation and honeycombing, otherwise NIP appeared relatively high score in inflammatory changes. Correlation between histopathologic scores and the clinical outcome after steroid therapy or no therapy in UIP was not evident.

On a standpoint of commonly available ESWL for the treatment of urinary stone, percutaneous stone extraction had the role of cooperation to it, and sometimes it could be the first procedure of choice. We have performed percutaneous extraction of the renal and upper ureteral stones in 35 renal unite. The overall success rate was 78.4%, average operation time was 81 minutes, mean fluoroscopic exposure time was 11 minutes, average postoperative hospital stay was 7 days. Causes of failure were as followings ; five inadequate calyceal puncture, one ureteral perforation, one impacted stone, and one downward stone migration. The complications were inappropriate position of the nephrostomy tube, prolonged hematuria through nephrostomy tube, and partial ureteral avulsion. They were not serious but resolved by conservative management.
