Because of observations that patients with acute episodes of alcoholic pancreatitis had high serum lipase levels whereas patients with gall stone pancreatitis had high serum amylase levels, a prospective study was undertaken to determine whether the ratio of serum lipase to serum amylase, a newly computed ratio, would discriminate between acute episodes of alcoholic and nonalcoholic pancreatitis. In phase one, 30 consecutive patients with acute pancreatitis were entered into the study and divided into groups A and B. Patients with renal failure were excluded from the study. Group A consisted of 20 patients in whom the etiology of pancreatitis was alcohol. Group B consisted of 10 patients whose pancreatitis was nonalcoholic in etiology (predominantly gallstones). Serum lipase values in group A ranged 492 to 25,706 U/L (median, 3433 U/L) and in group B from 711 to 31,153 U/L (median, 1260 U/L). These differences were not significant statistically. Serum amylase values in group A ranged from 104 to 2985 U/L (median, 331 U/L) and in group B from 423 to 13,000 (median, 1187 U/L). Although these figures were statistically different (P less than 0.005), there was a considerable degree of overlap in the values between the two groups. The lipase/amylase ratio calculated from the blood sample obtained at presentation appeared to be a promising discriminatory index. The lipase/amylase ratio was calculated by using the amylase and lipase levels expressed as multiples of the upper limit of normal in each case. The lipase/amylase ratios in the alcoholic group ranged from 2.2 to 14.8, whereas the lipase/amylase ratio in nonalcoholic pancreatitis ranged from 0.31 to 1.93. These differences were statistically significant (P less than 0.005). A lipase/amylase ratio of greater than 2 was indicative of an alcoholic etiology, and a ratio of less than 2 suggested that the pancreatitis was nonalcoholic in nature. In phase two, this lipase/amylase ratio of 2 was applied prospectively to an unselected population of 21 consecutive patients with acute pancreatitis. Thirteen patients had a lipase/amylase ratio of greater than 2; in 11 of them, the etiology of the pancreatitis was alcohol. Eight patients had a lipase/amylase ratio of less than 2; of them, only 1 patient had an alcoholic etiology for the pancreatitis. These differences were statistically significant (P less than 0.05).(ABSTRACT TRUNCATED AT 400 WORDS)

Hyperamylasemia has been documented in up to 65% of our patients with leptospirosis and jaundice. However, pancreatitis is an uncommon complication of leptospirosis. Three patients with leptospirosis and pancreatitis are described and compared with two leptospirosis patients who had hyperamylasemia but in whom the diagnosis of pancreatitis could not be substantiated. The cause of the hyperamylasemia in the latter patients was nonpancreatic. The elevation of the amylase in these latter two patients could not be explained by renal insufficiency, because the level of the amylase was greater than three to four times the normal value, the upper limit to which amylase rises in renal failure. Thus, hyperamylasemia in patients with leptospirosis can be from pancreatic and nonpancreatic sources. Leptospirosis should be considered in the differential diagnosis of hyperamylasemia and pancreatitis.

Total serum amylase activity, its isoenzymes and pancreatic to salivary amylase (P/S) ratio were studied in 40 normal subjects and 47 patients with renal failure, 32 with benign and 15 with malignant conditions. Amylase to creatinine clearance (Cam/Ccr) was studied in 17 normals and 14 patients with renal failure, 10 benign and 4 with malignant diseases. Total amylase activity, and pancreatic and salivary fractions were found to be increased by about 3.4 times the normal in both benign and malignant conditions producing renal failure though the P/S ratio was within the normal range. However, the increase in the urea and creatinine levels in patients could not be related to the increase in serum total amylase. Besides the Cam/Ccr ratio was elevated in patients with both benign and malignant conditions producing renal insufficiency whereas the Cam and Ccr were individually found to be decreased. Why patients with chronic renal failure in both conditions without clinical evidence of pancreatitis should have elevated Cam/Ccr ratio is not clear.

Sixty-three patients with severe acute pancreatitis have been studied. Pancreatitis was associated with biliary tract disease in 23 patients (36.5%) and with alcoholism in 21 (33.3%). It occurred post-operatively in 9, and was associated with other conditions in 10. We evaluated the Ranson prognostic signs (RPS) with the appearance of complications. 36 patients (57.2%) had 3-4 RPS, 9 (30.2%) had 5-6 RPS and 8 (12.6%) had 7 or more RPS. Diagnostic laparotomy was performed in 11 patients (17.5%). 55 patients were operated one or more times due to failure of medical treatment and/or local and septic complications. The most frequent complications were pancreatic abscess (60.3%), sepsis (58.7%) and pulmonary insufficiency (52.4%). Renal failure occurred in 26 patients and 9 required dialysis. Of the patients with renal failure, 84.6% (22/26) had 4 or more RPS; 78.4% (29/37) of those with sepsis and 71.6% (27/38) of those with pancreatic abscess also had 4 or more RPS. The mean duration of hospitalization of survivors was 58 +/- 30 days. Overall mortality was 28.6%. We conclude that RPS are helpful to predict complications in patients with severe pancreatitis.

Pediatric cases of systemic lupus erythematosus with an unfavorable outcome (terminal renal failure requiring chronic hemodialysis, or death) assembled during a retrospective multicenter study of pediatric SLE in the Paris metropolitan area were analyzed. Seven patients (6 girls, 1 boy) were entered into a chronic hemodialysis program. Four had diffuse proliferative glomerulonephritis, the pattern of glomerular disease classically responsible for end-stage renal failure. The other three patients had membranous glomerulonephritis with active segmental lesions, a form of glomerulopathy whose severe prognosis deserves to be emphasized. Nine other patients (8 girls, 1 boy) died. In six patients, death occurred as a result of a flare with malignant hypertension and progressive renal failure (1 case), pancreatitis (1 case), encephalopathy (2 cases) or cardiomyopathy (2 cases). An infectious disease (tuberculosis, mumps) was apparently the cause of the two cases of encephalopathy. One girl died as a result of a hemorrhagic syndrome with a cerebral hematoma. Two other girls died at home. Overall, among 111 children with SLE 14% had an unfavorable outcome. Sex and age at onset seemed to have no bearing on prognosis. Patients with renal involvement were apparently more likely to have an unfavorable outcome. Lastly, although the influence of ethnic origin is unproven, children living in foreign countries of French overseas territories, but treated in France have an increased risk for unfavorable outcomes.

Fourteen cases of acute severe pancreatitis complicated by non-traumatic rhabdomyolysis are described and compared to case controls. Pancreatitis of various aetiologies was confirmed by surgical diagnosis, laparotomy, abdominal paracentesis, CAT scan and post mortem. Pancreatitis was severe with a high Ranson prognostic score (7.4 +/- 0.5 vs controls 1.9 +/- 0.4, p less than 0.001), longer ICU admission and a mortality of 79%. Rhabdomyolysis occurred two to 19 days after the onset of pancreatitis (with a median CPK peak at 6.5 days) and was accompanied by multiple organ failure in 93% of cases. Severe rhabdomyolysis and myoglobinuric renal failure occurred in three patients out of 12 with acute renal failure. Hypocalcaemia was common (93%), severe (with a mean minimum value of 1.79 +/- 0.07 vs 2.34 +/- 0.04mmol/L, p less than 0.01) and prolonged (remaining abnormal for 5.2 +/- 0.8 vs 0.07 +/- 0.07 days, p less than 0.001). Intravenous calcium supplements were required in 50% of patients. Plasma phosphate, potassium, urate and anion gap were elevated (all p less than 0.05) and accompanying clinical features included fever, ascites, leucocytosis, hypoalbuminaemia and abnormal liver function tests. Rhabdomyolysis is associated with acute several pancreatitis, appearing as a late phenomenon in the context of severe prolonged hypocalcaemia, multiple organ failure and a poor outcome.

Carpentier described Tromboexclusion for treating aortic dissections type B claiming lower perioperative neurologic and haemorrhagic complications. We performed this operation in 12 exceptional cases with acute (6) and chronic (2) type B dissections, 2 patients with aorto-bronchial fistulas and infected grafts, and 2 patients with both thoracic and abdominal aneurysm. All patients were in haemorrhagic shock and had wall penetration or perforation. In addition to the Carpentier operation 3 aorto-subclavian, 2 aorto-bifemoral and 1 renal bypass grafts and 1 AVR and 2 ascending aorta replacements were performed. Seven patients died perioperatively: 3 because of massive haemorrhage and 4 due to pancreatitis and renal failure. Five patients survived the operation, three of those died 6-28 months later because of recurrent dissections. One sudden death one month after operation is unknown. One patient survived long term. In our patients, this operation showed high mortality rates and is therefore rarely recommendable.

Eighteen consecutive patients with sepsis due to surgically confirmed peripancreatic necrosis extending diffusely into the retroperitoneal fat were treated in our hospital from 1980 to 1987. Management consisted of early retroperitoneal debridement of necrotic tissue and drainage through lumbar incisions. Enteral nutrition was implemented in all patients 3-8 days after their first surgery. A total of 40 reoperations were required--an average of 2.6 per patient. Complications included respiratory failure (17), renal failure (4), gastrointestinal bleeding (4), retroperitoneal bleeding (1), and gastrointestinal fistulas (6). Four (22%) of the 18 patients died; the major cause of death was multiple organ failure secondary to sepsis. Before 1980, all patients with severe pancreatitis treated in our hospital died, despite the use of different management techniques. The use of the extraperitoneal route for early debridement of necrotic tissue and to avoid contamination of the peritoneal cavity has substantially reduced the mortality associated with peripancreatic necrosis in our hospital. The mortality in this series of patients (22%) compares very favorably with that reported in studies of similar patients.

Sonographic identification of thickening of the gallbladder wall that consists of multiple striations (alternate hypoechoic and hyperechoic layers) has been considered strong evidence of the presence of acute cholecystitis. We studied 27 patients in whom sonograms showed striated thickening of the gallbladder wall to determine the diagnostic significance of this finding. Striations were classified as focal or diffuse. Sonograms were correlated with pathologic findings in 16 patients and with clinical diagnoses and laboratory findings in 11. Patients were categorized as having cholecystitis with or without gangrene or edema of the gallbladder wall unrelated to gallbladder disease. Striated thickening of the gallbladder wall was due to cholecystitis in 10 patients, and all 10 had gangrenous changes at surgery or at pathologic examination. Striations were focal in eight of these patients and diffuse in two. Striated thickening of the gallbladder wall was due to edema of the wall unrelated to gallbladder disease in 17 patients. Causes included congestive heart failure (n = 4), renal failure (n = 5), liver disease (hepatic failure [n = 1], hepatitis [n = 6]), ascites (n = 2), hypoalbuminemia (n = 3), pancreatitis (n = 1), blockage of the lymphatic/venous drainage of the gallbladder (n = 2), and prominent Rokitansky-Aschoff sinuses (n = 1). More than one abnormality was present in five patients. Striations were focal in 11 of these patients and diffuse in six. The sonographic finding of striated gallbladder wall thickening is no more specific for cholecystitis than the observation of gallbladder wall thickening by itself, and it may occur in a variety of diseases. However, in the clinical setting of acute cholecystitis, the presence of striations suggests gangrenous changes in the gallbladder. The extent of the striations (focal or diffuse) is not useful in predicting the cause of the striated gallbladder wall thickening.

Because the important increase of cocaine abuse and the frequent pathology associated, we present two cases of males who had a multiorganic failure cause by severe rabdomyolysis, renal failure with myoglobinuria and disseminated intravascular coagulation, after the cocaine consumption. In one case a pancreatitis associated was observed, this not being described before. Both cases are recovered.
