The present study was done to determine the additional influence of daily ethanol intake (15% in drinking water ad libitum) on long-term toxic effects of a single administration of dibutyltin dichloride (DBTC, 8 mg/kg b.w. i.v.) in pancreas and liver of rats. Pathohistological changes in pancreas, bile duct and liver as well as pathobiochemical parameters of pancreatitis (amylase and lipase activity), liver lesions (alkaline phosphatase activity and bilirubin) and fibrosis (hydroxyproline and hyaluronic acid) were measured 1 day and 1 to 24 weeks after DBTC- and DBTC/ethanol administration. DBTC alone induced in rats an acute interstitial pancreatitis as well as acute bile duct and liver lesions in the early experimental phase. Later on, the acute inflammatory processes in pancreas and liver took a chronic course resulting in pancreatic fibrosis and liver cirrhosis. Ethanol increased the toxic effects of DBTC on pancreas and liver during the acute and chronic course. In the acute phase lasting 1 day to 2 weeks, ethanol enhanced the DBTC toxicity on acinar cell and bilio-pancreatic duct epithelium as well as the formation of obstructive ductal plugs by necrotic cell debris. The obstruction and cholestasis in the DBTC/ethanol-group were significantly stronger as in the DBTC-group. The significant increase of hydroxyproline in urine and hyaluronic acid in serum of the DBTC/ethanol treated rats after 12 to 24 weeks was connected with a more severe chronic inflammatory fibrosis in pancreas and liver in comparison to the DBTC-treated group.

Preoperative and postoperative values of amylase were assessed in patients submitted to hepatic resections for primary or secondary liver tumours. Among these 40 had underlying liver cirrhosis and 18 normal liver. Preoperative serum amylase levels were increased in patients with cirrhosis. Postoperative amylase levels were found to be overlapping to preoperative one both in patients with normal and cirrhotic liver when no Pringle's manoeuvre was used in the course of surgery. A significant postoperative increase in serum amylase levels was detected in the group of patients where liver resection was carried out under Pringle's manoeuvre. Two patients of the cirrhotic group developed mild pancreatitis. It is suggested that portal congestion relates morphological changes of pancreas and hyperamylasemia and that Pringle's manoeuvre, if prolonged, carries a potential risk of pancreatitis especially in patients with underlying liver cirrhosis.

The aim of the present study was to find the cause of inter-laboratory differences in laboratory test data and to examine whether control assessment helps to reduce inter-laboratory differences. Blood and serum samples of one healthy subject and one subject with liver cirrhosis were analyzed by 11 laboratories in the Okayama City area. No differences were found in the assay units of 26 tests surveyed. However, considerable differences were observed in test data, reference interval, and clinical level (CL), though most laboratories pointed out that the test data for the normal subject was within the reference intervals and those for the patient with liver cirrhosis showed abnormalities in tests for liver function. The difference in reference intervals was serious in the tests of direct bilirubin (D-Bil), thymol turbidity test (TTT), alkaline phosphatase (ALP), gamma-glutamyltranspeptidase (GGTP) and choline sterase. Marked differences in CLs were found in the tests of D-Bil, TTT, ALP, GGTP, creatine phosphokinase, amylase, heavy density lipoprotein cholesterol and white blood cell count. However, three hepatologists independently suggested that such inter-laboratory differences would not seriously affect a clinical decision on the disease status of the cirrhotic patient. Most tests that showed a trend error in a recent quality control survey appeared to have the same trend in the present study. These results indicate that inter-laboratory differences occur at various levels and control assessment are helpful in establishing, and therefore reducing, the level of inter-laboratory differences.

Serum amylase and lipase concentrations were determined in 78 patients with chronic liver diseases [26 chronic active hepatitis (CAH) and 52 liver cirrhosis] and in 15 healthy subjects. Pancreatic isoamylase concentrations and macroamylase complexes were assayed in hyperamylasemic sera. Serum amylase levels were abnormally elevated in 27 patients (35%; 22 liver cirrhosis, 5 CAH), whereas serum lipase levels were elevated in 16 patients (21%; 15 liver cirrhosis, 1 CAH). In 9 of the 27 hyperamylasemic patients, the hyperamylasemia was of pancreatic type. Macroamylasemic complexes were not detected in hyperamylasemic sera. Patients with liver cirrhosis had serum levels of amylase and lipase significantly higher than both the healthy subjects and the patients with CAH, while no significant differences were found in serum levels of these enzymes in patients with CAH as compared to the healthy subjects. A decreased liver metabolism of serum amylase and lipase in patients with chronic infective liver disease, especially in those having liver cirrhosis, may lead to an accumulation of these enzymes in the blood.

We have investigated the clinical characteristics of renal damage and associated complications of 79 patients with accidental hypothermia whom we encountered over the last 5 years. All patients were male, with an average age of 58.9 +/- 9.2 years. Most of these patients were homeless. Body temperature on admission was 29.3 +/- 3.0 degrees C. The most common clinical manifestations on admission were consciousness disturbance and severe hypotension. Complications, including increase in serum transaminase, alcoholism, pneumonia, liver cirrhosis, sepsis, diabetes mellitus, hypoglycemia, acidosis, and an increased level of serum CPK and amylase were found frequently on admission. Death within 48 hours after admission occurred in 23 cases (the death rate; 23/79 = 29%). Renal damage was found in 36 cases (36/79 = 46%), consisting of acute renal failure (ARF) in 27, and acute on chronic in 6. Urinary diagnostic indices suggested that the etiological factor for ARF was pre-renal, which responded well to passive rewarming and an appropriate fluid replacement therapy, resulting in full recovery in most of the cases (the recovery rate; 25/27 = 93%). Among patients with renal damage, there were no cases requiring dialysis. The present data suggest that accidental hypothermia is a fatal condition with an extremely high death rate. It also is associated with multiple complications including ARF. The main cause for ARF is pre-renal, possibly caused by cold diuresis or dehydration superimposed on the underlying diseases such as alcoholism, diabetes mellitus, liver cirrhosis. Such complications, independent of renal damage, determine the patient's prognosis.

1. Dialkyltin compounds have been widely used in industry and agriculture, mainly as biocides, catalysts and plast stabilizer. In dependence on the length of the alkyl chains these organotins exert toxic effects on the immune system, the bile duct, liver and pancreas. It has been supposed that similar to organoarsenic the toxicity of the dialkyltin compounds is related to reactions with biological dithiol groups. Therefore, in the present study, the antidotal effects of 2,3-dimercapto-propane-1-sulfonic acid (DMPS) and meso-2,3-dimercaptosuccinic acid (DMSA) on the organotoxic effects of dibutyltin dichloride (DBTC, single administration of 27 micromol kg(-1) b.w. i.v.) in rats were studied using different doses (100 and 500 micromol kg(-1) b.w.) and routes of administration (i.p. and p.o.) of both chelators. Several parameters of organotoxicity (thymus weight and cellularity, bile duct diameter, histological lesions of pancreas and liver, activities of amylase, lipase and alkaline phosphatase, bilirubin and hyaluronic acid in serum) were measured from 6 h to 8 weeks. 2. DMPS and DMSA diminished the DBTC induced bile duct, pancreas and liver lesions stronger than the thymus atrophy. Moreover, the development of a fibrosis of the pancreas and a cirrhosis of liver several weeks after single administration of DBTC to rats was inhibited by DMPS and DMSA. The antidotal effects on serum parameter were observed after both administration routes of the chelators. DMPS was more effective than DMSA in most measured parameters. The decrease in the biliary excretion of organotin by DMPS and DMSA seems to be the reason for the pronounced protective effects of DMPS and DMSA on bile duct, pancreas and liver. 3. For the treatment of poisonings with dibutyltin compounds, the administration of DMPS or DMSA can be recommended.

A case of erythropoietic protoporphyria associated with severe hepatic dysfunction and acute pancreatitis is reported. The patient, a 33-year-old man, was admitted to our hospital complaining of upper abdominal pain, nausea, and vomiting of 3 days' duration. Laboratory tests on admission demonstrated liver dysfunction, anemia, and thrombocytopenia. On the third hospital day, the intensity of the upper abdominal pain increased, concomitantly with elevated levels of serum amylase. Ultrasonography and computed tomography scanning revealed a slightly enlarged pancreas. During this episode, he also complained of various neurological symptoms, including reduced mental alertness, weakness of extremities, constipation, profound sweating, and urinary retention. Porphyrin studies demonstrated markedly elevated erythrocyte and fecal protoporphyrin levels. Laparoscopic findings obtained after the attack subsided were compatible with porphyric liver cirrhosis. We therefore concluded that neurologic disorders and acute pancreatitis could develop in patients with erythropoietic protoporphyria with severe liver dysfunction.

Di-n-butyltin dichloride (DBTC) induced thymus atrophy, bile duct lesions, pancreatitis, and liver lesions in rats. Depending on dose [6 and 8 mg/kg intravenous (i.v.) DBTC] and time (1-24 weeks), the lesions in pancreas developed to a pancreatic fibrosis and the lesions in liver to liver cirrhosis. A single i.v. administration of 4 mg/kg DBTC induces a mild interstitial pancreatitis after 2-4 days followed by a restitutio ad integrum after 21-28 days. In the present study, the lesions of biliopancreatic duct, pancreas, and liver of rats after repeated administration of 4 mg/kg DBTC i.v. at intervals of 3 weeks have been investigated. The histopathological changes of pancreas and liver were examined by light microscopy 1,4, and 7 days and 2,3,4,6,9, and 12 weeks after administration of DBTC. Furthermore, pathobiochemical parameters of pancreatitis (amylase and lipase activity in serum), liver lesions (alkaline phosphatase activity and bilirubin in serum), and of fibrosis (hyaluronic acid in serum) were studied. Repeated administration of rats with DBTC (4 mg/kg i.v.) at intervals of 3 weeks induced an acute interstitial pancreatitis and after 9-12 weeks, a pancreatic fibrosis and liver lesions (intrahepatic bile duct hyperplasia, inflammation in periportal tract, and necrosis). In serum, elevated levels of alkaline phosphatase, bilirubin, and hyaluronic acid were found. This study demonstrates that the organotin compound induces toxic effects on pancreas and liver of rats by repeated administration of lower doses at long intervals. The risk of exposure to organotin at long intervals should be considered.

Hemobilia is an rare cause of acute pancreatitis. The most frequent causes are iatrogenic trauma (percutaneous liver biopsy) and hepatic artery aneurysm. To our knowledge, this is the second published case of acute pancreatitis related to hemobilia secondary to hepatocarcinoma complicated cirrhosis in a patient treated with anticoagulants for a mechanical valvular aortic prosthesis. The clinical picture included acute epigastric pain, fever and jaundice. Increased amylase and lipase serum activities, and abdominal CT data confirmed the diagnosis of acute pancreatitis. Gallstone induced acute pancreatitis was suspected and thus, a cholecystectomy was performed. No bile duct stones were found but a clot was extracted from the extrahepatic bile duct during surgery. Arterial embolization was then performed and repeated 1 and 3 months later for recurrence. The patient was asymptomatic eight months later. Hepatic arterial embolization is an effective haemostatic treatment for hemobilia, even though, in this case treatment had to be repeated because of an anticoagulant therapy.

A 39-year-old white man with a history of right renal pelvic stones treated 1 year before by extracorporeal shock wave lithotripsy, but with no history of major surgery, alcoholism, pancreatitis, hyperparathyroidism or trauma, was admitted, suffering from an abdominal mass. Abdominal and pelvic computed tomography revealed an enlarged pancreatic head (9 cm in transverse diameter) with, inside it, a heterogeneous, cyst-like structure, measuring 7 cm in diameter. It was suspected that this lesion was a cystic neoplasm and the patient underwent a proximal pancreaticoduodenectomy and a cholecystectomy. After the operation, the microscopic findings ruled out the presence of a neoplasm and we were obliged to reconsider the case. Speculating as to the possible role of past extracorporeal shock wave lithotripsy in determining the pancreatic pseudocyst, it was found that damage to the intra-abdominal organs during extracorporeal shock wave lithotripsy has been mentioned in published series, but it was also noted that this case seemed to differ from the other published cases, where cirrhosis and thrombocytopenia, gallbladder stones, or adhesions between the pancreas and surrounding tissue caused by laparotomy were considered the causes of the lithotripsy complications. We suggest a direct traumatic disruption of the pancreas as a result of the extracorporeal shock wave lithotripsy and conclude that the post-lithotripsy follow-up should include periodic ultrasonographic investigation of the pancreas and serum amylase level determinations in order to diagnose pancreatic complications, if any, and plan the correct treatment.
