Diagnostic significance of a simple and rapid screening procedure for determining the relative amounts of pancreatic and salivary isoamylase using an amylase inhibitor was evaluated in 242 subjects (controls 84, acute pancreatitis nine, chronic pancreatitis 28, pancreatic cancer 14, peptic ulcer 25, liver cirrhosis 15, cholelithiasis 24, irritable colon syndrome 13, diabetes mellitus 13, mumps seven, and chronic renal failure 10). Electrophoretically separated isoamylases of saliva and pure pancreatic juice were all inhibited at similar degrees to the corresponding unfractionated amylases. Total amylase and pancreatic isoamylase were elevated in all nine patients with acute pancreatitis. Pancreatic isoamylase was decreased in 12 of 28 patients (43%) with chronic pancreatitis and increased in nine of 14 patients (64%) with pancreatic cancer. The mean pancreatic isoamylase activity in the patients with acute pancreatitis was significantly higher (p less than 0.01), while that of chronic pancreatitis was significantly lower (p less than 0.05) when compared with controls. The inhibition method offers simple, rapid, and specific analysis of serum isoamylase for the differential diagnosis of hyperamylasemia in cases of emergency.

An analysis is presented of 73 attacks of acute pancreatitis treated with non-operative peritoneal lavage, classified according to Ranson's 11 signs and followed up for on average four years. None of the 21 moderate attacks was associated with complications or mortality. In the 52 severe attacks, four patients (7.7%) died, new pseudocyst developed in five patients (9.6%) and abscess in four (7.7%), and diabetes was found in 12 patients (23%) at follow-up. In all these respects the severe attacks showed statistically significant difference from the moderate attacks, as did the need for assisted ventilation, the volume of gastric retention and the length of hospital stay. The authors conclude that non-operative peritoneal lavage is beneficial, probably by removing toxic substances from the peritoneal cavity.

A 32-year-old man was admitted semi-comatose with digestive troubles to the hospital. A diabetic keto-acidosis was discovered. The diabetes was known by the patient for one year and a half, but it was not treated. Furthermore the laboratory studies showed a hyperlipidemia (type V) and an increase in pancreatic enzymes. The hyperlipidemia disappeared with insulin therapy. The chronology of the facts was probably: a hyperlipidemia associated with the diabetes, responsible of an acute pancreatitis, which induced a keto-acidosis.

In a survey the present possibilities are outlined to get knowledge about diseases of inner organs with the help of enzyme determinations in the urine. Here it is remarkable that changes of the enzyme excretion appear not only in renal disease with acute renal failure, pyelonephritis, glomerulonephritis, renal infarction and nephroptosis but are also to be observed in primarily extrarenal diseases such as diabetes mellitus, hyperthyroidism, thesaurismoses, myocardial infarction, hypertension, acute pancreatitis, epidemic hepatitis, liver cirrhosis, obstructive jaundice and rheumatoid arthritis. The causes of the changes of enzyme excretions are various. Since enzymes of different origin and localisation behave themselves variably, the simultaneous determination of a brush border marker (e.g. alanine aminopeptidase), a lysosomal enzyme (e.g. beta-glucuronidase or N-acetyl glucosaminidase) and a low molecular enzyme (e.g. lysozyme) is of use for the recognition of renal alterations. By the control of activities of urinary enzymes it is possible to get without risk informations about pathobiochemical processes in the kidney which are not to be gained by means of other methods.

Diabetes and carbohydrate intolerance can occur in pancreatitis. Although one-half of patients with acute pancreatitis will have some evidence of glucose intolerance during their acute illness, few will require insulin administration on either a short- or long-term basis. The diabetes seen in acute pancreatitis is likely due to a combination of factors, including alerted insulin secretion, increased glucagon release, and decreased glucose utilization by the liver and peripheral tissue. Chronic pancreatitis is often associated with diabetes mellitus, with the incidence as high as 70 percent when pancreatic calcification is present. These patients tend to be very sensitive to the effects of insulin and hypoglycemia. This is probably secondary to concurrent hepatic disease, malnutrition, and a relative decrease in glucagon reserves. The diabetes seen in chronic pancreatitis is associated with decreased insulin production. Finally, although the endocrine pancreas may influence the exocrine gland through a portal system, primary diabetes mellitus probably does not result in clinically significant alterations in pancreatic exocrine function.

Forty five cases of chronic pancreatitis have been diagnosed between January 1966 to July 1983 in the Hospital A. Posadas. The diagnosis was confirmed by the presence of one or more of the following data: pancreatic calcifications positive in 35, abnormal secretin test 37, ultrasonography and computed tomography pathological findings 10. Surgical operations were carried out in 25 patients and biopsy taken in 5. Thirty nine (86.6%) were males, 6 (13.3%) females, the mean age in each group was 47.4 and 39.8 years. Chronic alcoholism was certain in 41 (91.9) patients, in the remainder 4 no other etiologic factors were found. The main clinical data were: Weight loss 38 (84.4%) diabetes 34 (75.5%) pain 33 (73.3% in 7 as acute pancreatitis) Steatorrhea 23 (51.1%) jaundice 16 (35.5%- 11 by extrahepatic biliary tree obstruction, 5 by hepatic cirrhosis) pseudocysts 12 (26.6%). The more common associated diseases were: hepatic cirrhosis 6, fatty liver 2 (17.7%) gastroduodenal ulcer 6 (13.3%) cancer 4 (8.8%--gastric 1, pancreatic 3). In order to study the frequency of the clinical data the patients were grouped according to the presence or absence of calcifications and the etiologic factor Symptoms and signs were matched and statistic analysis (coefficient association phi) was made. Only a moderate association between acute pancreatitis in no calcified group and diabetes in calcified group were found. The chronologic study of certains clinical data shows that acute pancreatitis, jaundice, pseudo-cyst and surgical operations were significative more frequent in the first five years while diabetes has little more frequency in the second five year period. Twenty six surgical operations were carried out in 25 patients; 20 (76.9%) due to complications, 6 (23.1%) secondary to pain (pancreatic resection 3, pancreatoyeyunostomy 2, exploration 1). Twenty three patients were lost to follow-up, 12 died and 10 are still alive. This last group was followed at regular period, 8 remained asymptomatic and 2 have intermittent abdominal pain related to alcoholic ingestion.

Usually, ketoacidosis presents few if any diagnostic or therapeutic problems; in this article, we report a case where ketoacidosis was clinically occult and biochemically obscure. The patient presented with acute pancreatitis associated with a modest antecedent alcohol intake. Metabolic acidosis with a normal anion gap (10 meq/L) was observed together with moderate hyperglycemia and a 2 + (but not 4 +) test for serum ketones. None of the usual causes of metabolic acidosis with a normal anion gap was identified nor was there an obvious explanation for a reduction in unmeasured anion gap (e.g., hypoalbuminemia, dysproteinemia, or the presence of abnormal halides). Despite the initial normal anion gap, ketoacidosis was suspected clinically and this was confirmed by the elevated serum B-hydroxybutyrate of 8 mmol/L. We deduced that the serum unmeasured anions, which should have been increased by at least 8 meq/L, were being underestimated because of the effect of hypertriglyceridemia on the serum chloride determination. When the serum chloride was reestimated by a method not influenced by hyperlipidemia, the value was 102 mmol/L not 112 mmol/L and, when reevaluated, the anion gap was indeed appropriately elevated. In addition, the urine anion gap (Na + K - Cl) was 103 meq/L in the absence of renal disease. This indicated that the expected large quantity of urinary ammonium must have been masked by an even greater quantity of unmeasured anion; in this case proven by direct measurement to be B-hydroxybutyrate. Finally, metabolism of the alcohol ingested, which yields hepatic NADH, could explain, in part, the modest hyperglycemia and the absence of a 4 + test for serum ketones.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors make a retrospective analysis of 95 cases of acute pancreatitis hospitalized between 1975 and 1979. In 3,8% of all the cases the acute pancreatitis was associated with hyperlipoproteinemia. The study of the 4 patients involved revealed the primary origin of hyperlipoproteinemia as a result of alimentary abuse in 3 of the cases. In a fourth case the increased serum lipoproteins were due to prolonged use of contraceptives. From the clinical viewpoint, pancreatitis associated with hyperlipoproteinemia was more severe, with signs of shock and collapse, respiratory failure, high serum nitrogen an hyperglycemia. The blood and the serum had a lactescent aspect, with a thick layer of chylomicrons. The serum and blood values for lipids were higher than 4000 mg%. The increase in the amount of lipids was especially due to high triglycerides values. From the anatomopathologic viewpoint the 4 patients presented as acute cases of cholecysto-pancreatitis with major and extensive haemorrhagic necrosis which involved almost the entire pancreas. The evolution of the four patients was difficult. Two of the patients recovered after a long hospitalization, and had definitive sequels - insulin-dependent diabetes. The other two patients died following septic complications (bronchopneumonia and visceral gangrene), and hypovolemia due to upper digestive haemorrhage.

Based on the results of treatment of a personal series of 13 cases of pseudocyst of the pancreas, between 1974 and the present day, it is suggested that the choice of therapy should be surgical. An internal shunt is preferred for pseudocysts as a result of acute pancreatitis or injury, whereas a wider cysto-wirsung jejunostomy is recommended for cysts developing during the course of chronic pancreatitis. These proposals follow analysis of immediate and long-term (mean: 51 months) follow-up, on the basis of mortality, morbidity, pain symptoms, malabsorption and postoperative diabetes.

Thirty patients with cysts of the cephalic portion of the pancreas treated by operation between 1966 and 1980 were reviewed to determine whether any variation existed from the usual treatment of cysts of the body and tail of the gland. Sixteen patients had chronic pancreatitis, six had acute pancreatitis, four had cysts of indeterminate causes, three had adenocarcinoma of the pancreas, and in one patient a cyst developed after external trauma. External drainage was used in 14 patients, internal drainage in ten patients, and combinations of cyst drainage and anastomosis of Wirsung's duct or resection were performed in six patients. No operative deaths occurred, and the rate of cyst recurrence was minimal. Diabetes mellitus developed in 40% of patients with chronic pancreatitis despite conservative management. Recurrent pain in 13 patients and the discovery of associated carcinoma in one patient at initial treatment and later in two others cast doubt on the usefulness of simple internal or external drainage of cysts for pain except in a setting of acute pancreatitis. Resection of the pancreatic head or drainage of dilated pancreatic ducts should more often be carried out in the primary treatment of cephalic cysts with pain due to chronic pancreatitis.
