Pulmonary blastoma is a rare lung tumor resembling fetal lung tissue. Pathologically the tumor can be classified to 2 groups, well-differentiated fetal adenocarcinoma(WDFA) and biphasic blastoma. WDFA has more favorable prognosis with fewer metastasis at initial presentation and fewer recurrence after treatment. We experienced a case of pulmonary blastoma in 32-year-old female patient. The patient was referred to our hospital because of abnormal mass shadow in right middle lobe. The diagnosis of pulmonary blastoma(WDFA type, Stage I T2NOMO) was confirmed after right middle lobectomy. We followed up 22 months without an evidence of recurrence.

Background/Aims:
Using an appropriate guidewire can increase the success rate of selective cannulation in endoscopic retrograde cholangiopancreatography. The purpose of this technical study was to investigate the characteristics of each guidewire type and to evaluate its efficiency and rapidity of insertion.
Methods:
We conducted a three-point bending test using a universal testing machine to investigate the flexibility and bending features of each guidewire. 3D-printed silicone tubes with various types of stricture and a hand-made biliary tree silicone model with six-stranded intrahepatic ducts were used to evaluate the success rate and insertion time of each guidewire.
Results:
In the three-point bending test, the characteristics of each guidewire were classified. We found that the bending strengths and times were independent of shaft thickness. Using two in vitro biliary duct models, we determined that the success rate and total insertion time were better for guidewires with a resilient shaft and angled tip than for other types of guidewires (p<0.001). Although thickness of the guidewire affected the success rate (p<0.05), it did not affect the total insertion time (p≥0.05).
Conclusions
Among several types of guidewire, some factors (resilient shaft, highly flexible, and angled tip) appeared to be associated with the efficiency and rapidity of the guidewire insertion.

BACKGROUND/AIMS: Ascites is a fairly common condition, but the clinical features of pseudomembranous colitis with ascites are not well-known. The aim of this study was to determine how the existence of ascites is related to the clinical factors. METHODS: Between March 2002 and June 2006, 67 pseudomembranous colits patients were diagnosed by performing lower endoscopy and biopsy. The patients' ascites was identified by abdominal plain radiography, ultrasonography or computerized tomography. The extension of colitis was evaluated by ultrasonography or computerized tomography. RESULTS: 16 patients (23.9%) had ascites. The serum WBC (p=0.01), hypoalbuminemia (p<0.01), CRP (p<0.01), recurrence (p<0.01), and extension of colitis (p<0.01) were associated with the existence of ascites. The four patients who had undergone paracentesis had a low SAAG level and PMN dominant ascites. CONCLUSIONS: There were correlations of ascities with leukocytosis, hypoalbuminemia, CRP, extension of colitis and recurrence of PMC.

Within the past few years, an increasing number of reports of Hodgkin's disease following the diagnosis of, and frequently coexisting with, mycosis fungoides have appeared. Previously, Hodgkin's disease found in the lymph nodes of the patient diagnosed as mycosis fungoides was considered as a transformed form of the mycosis fungoides. But, now it has been proven that Hodgkin's disease and mycosis fungoides are histologically and immunohistochemically distinct disease entities. We report a well-documented case of a man who developed Hodgkin's disease and mycosis fungoides simultaneously as a composite lymphoma. Our case emphasizes the importance of considering the diagnosis of another lymphoma in patients with mycosis fungoides who have lymphadenopathy. The cutaneous mycosis fungoides and the Hodgkin's disease should be treated as an independent disease.
