A pancreatic pseudocyst is a relatively rare complication of pancreatitis. Various factors, such as inflammatory process or trauma, are among the possible cause of pancreatitis. A pancreatic pseudocyst is often defined as a localized collection of pancreatic juice in the retroperitoneal area surrounded by a fibrous membrane devoid of an epithelial lining. The hospital records of 52 cases of pancreatic pseudocyst treated at Kyungpook National University Hospital from 1976 through 1994 were reviewed and analysed. The results are as follows : 1) The age distribution of these cases showed that 57.7% occurred in the 3rd and the 4th decades. The male to female ratio was 3.7 : 1 2) The etiology of the pseudocysts was pancreatitis in 46.2% of the cases and trauma, unknown etiology, pancreatic cancer and hyperlipidemia, in that order, in the other cases. 3) Abdominal pain was the most common symptom (86.4%); a palpable mass (65.4%), abdominal tenderness (65.3%) also occurred. 4) Abdominal C.T. and Ultrasonogram has a diagnostic accuracy as 100%, and U.G.I. showed a diagnostic accuracy of 76.5%. 5) Among the 52 cases, 30 cases received surgical treatment 13 cases were treated by percutaneous catheter drainage. 6) With respect to the operative procedure, internal drainage was performed in 18 cases (60%), external drainage in 8 cases (26.7%), excision in 3 cases (10.0%), and O & C in 1 case (3.3%). 7) Thirteen percutaneous catheter drainage procedures were performed, and the success rate was 92.3%.

OBJECTIVE: In this study, the exposure levels of polycyclic aromatic hydrocarbons (PAHs) and urinary 1-hydroxypyrene(1-OHP) were surveyed among the workers using coal tar paint. METHOD: The study subjects for the exposed group were 107 male coal tar workers in 10 factories, and for the comparison group were 201 male clerk workers who had never been exposed to coal tar paint. Ambient PAHs, and pre-shift and end-shift urinary 1-OHP were sample and 16 PAHs were analysed. Smoking history was recorded during the survey day. RESULTS: The geometric mean of ambient concentration of total PAHs was 120.17 microgram/m3. Naphthalene had the highest level among the 16 PAHs. The pre-shift 1-OHP in the exposed group (8.89 micro mol/mol creatinine) was significantly higher than that in the control group (0.29 micro mol/mol creatinine). The end-shift 1-OHP in the exposed group (19.02 micro mol/mol creatinine) was significantly higher than that in the pre-shift (8.89 micro mol/mol creatinine) (Ed- confirm). 1-OHP of smokers was significantly higher than that of non-smokers in both groups. The difference between pre-shift and end-shift 1-OHP in smokers (12.40 micro mol/mol creatinine) was twice as high as that in non-smokers (6.06 micro mol/mol creatinine). The difference of 1-OHP between smokers and nonsmokers was 7.59 micro mol/mol creatinine in pre-shift and 13.96 micro mol/mol creatinine in end-shift. Thus, the effect of smoking and exposure to PAHs on 1-OHP may not be additive. In regression analysis for 1-OHP, the significant independent variables were pre-shift 1-OHP and PAHs. The direction of these variables was positive. When the analysis was performed in workers exposed to higher PAHs, smoking was significant independent variable. CONCLUSION: The above results suggest that not only ambient PAHs but also smoking, one of the most important non-occupational PAHs source, influenced the level of 1-OHP. Moreover, the effect of smoking to 1-OHP changed according to the exposure level of PAHs.
