Twelve cases of pancreatic abscess, managed at two hospitals in the District of Columbia, are analyzed. Forty-two percent of cases followed acute pancreatitis and infected pancreatic pseudocysts without previous surgical intervention. In 58 percent of the patients, pancreatic abscess was a complication of internal drainage of pancreatic pseudocysts. A discussion ...

Synovial fluid cryoproteins from various inflammatory and noninflammatory arthritides were examined for the presence of immunoglobulin, fibrinogen, antiglobulin activity, and third component of complement and correlated with the synovial fluid leucocyte count. The majority of rheumatoid synovial fluid cryoproteins contained either IgG-IgM complexes or IgG alone. Contrary to previous reports, ...

A patient with recurrent episodes of acute pancreatitis found to be caused by the presence of a choledochocele is presented. Transhepatic cinecholangiography revealed a choledochocele receiving the terminations of the common bile duct and pancreatic duct, which emptied via a pinpoint opening into the duodenum. With duodenal peristalsis, the contrast ...

Enlarged spleen without a clear-cut etiology, and believed to be related to malarial infestations, has been referred to as "tropical splenomegaly" and "cryptogenetic splenomegaly." Splenectomy performed in such cases after a failure of antimalarial therapy shows histopathologically, while some of these meet the criteria for tropical splenomegaly, that most were ...

Acute pancreatitis was an unexpected complication during the course of intensive supportive management in five patients with Reye's syndrome. Four of the five patients died and one survived with transient neurologic deficits. Although corticosteroid therapy, fluid restriction, and hypothermia may have contributed to the development of this complication, acute pancreatitis ...

Evidence that VIP is the principal humoral mediator of the watery diarrhea syndrome includes: (a) actions of VIP in experimental anaimals parallel the clinical manifestations of the syndrome; (b) infusions of VIP induce watery diarrhea in intestinal loops of dogs and a picture resembling the clinical syndrome in pigs, at ...

This report summarizes the course of a patient with asymptomatic chronic pancreatitis associated with hemorrhage into the pancreatic duct and metastatic fat necrosis. Retrograde cannulation of the pancreatic duct and superior mesenteric arteriography established the presence of a pseudocyst with a pancreatic duct-arteriovenous (DAV) fistula as the cause of the ...

Intraductal administration of enterokinase in rats produced hyperamylasemia and acute hemorrhagic pancreatitis. The experimental pancreatitis and hyperamylasemia could be prevented by the concomitant intraductal injection of fluorouracil, pituitrin, or chlorophyll-a. The clinical implication of the study is that these agents, if given intraductally, may be useful in the prevention of ...

A 43-year old man with CRST syndrome (calcinosis, Raynaud's phenomenon, sclerodactyly and telangiectasia) and progressive systemic sclerosis presented with a four-year history of relapsing abdominal pain, the result of chronic pancreatitis, not associated with alcoholism, biliary disease, or any of the known causes of pancreatitis. He had a good response ...

A syndrome of in vitro properties correlates with the tumorigenicity of SV40-transformed rodent cells. These properties are: plasminogen activator production, loss of large actin cables, and anchorage-independent growth. An established rat fibroblast line, its SV40 transformant, several T-antigen negative revertants, and a spontaneous retransformant isolated from one of the revertants ...

Basal human pancreatic polypeptide (H.P.P.) concentrations have been measured in 41 pateints with Zollinger-Ellison syndrome (Z.E.S.) and in 100 controls. Basal H.P.P. concentrations in controls varied widely from less than 8 pmol/l (assay detection limit) to 313 pmol/l. In controls, but not in the Z.E.S. patients, there was a highly ...

Two unusual cases of the watery diarrhea syndrome are presented. In one patient an adrenal medullary tumor, a pheochromocytoma that produced vasoactive intestinal polypeptide (VIP) was excised with total relief of symptoms. The second patient a 65-year-old man with abrupt onset of massive watery diarrhea that led to acidosis and ...

Early cleavage stage (4- and uncompacted 8-cell) embryos from experimental (+/tw32 X +/t32) and control (male +/tw32 X female +/T) matings were recovered at 56 hours post coitum, cultured, separated into uncompacted and compacted 8-cell embryo groups, and either analyzed histologically for cytoplasmic lipids or cultured through the morula-to-blastocyst transformation. ...

A 2-year-old child with intestinal malrotation had simultaneous gastric volvulus, midgut volvulus, acute pancreatitis, and gastric perforation, followed postoperatively by a temporary period of both lactosuria and sucrosuria. The gastric volvulus and midgut volvulus resulted in both proximal and distal obstruction of the duodenum, reproducing clinically a previously reported experimental ...

A clinical and histopathological description of exocrine pancreatic insufficiency syndrome in CBA/J mice is presented. Amelioration of clinical symptoms by pancreatic enzyme replacement therapy is described, as are breeding experiments designed to test the hypothesis that the etiology of this syndrome is a recessive mutation. Our failure to propagate the ...

The differential effects of role-played vs. hypnotically induced simulation of a paranoid syndrome on diagnostic and validity scales of the MMPI were tested with 30 female undergraduate Ss. Hypnotized Ss given the paranoid syndrome suggestion simulated the MMPI more accurately than did role-playing Ss. The F scale and Gough F-K ...

The possible factors in the pathogenesis of the brain damage and megaloblastic anaemia in the Lesch-Nyhan syndrome are discussed. Disordered growth and function appear to be limited to the brain, bone marrow and general body stature, yet the purine salvage enzyme hypoxanthine-guanine phosphoribosyltransferase (EC 2.4.2.8, HGPRT), although present in variable ...

Intraperitoneal injections of avian pancreatic polypeptide (APP) and bovine pancreatic polypeptide (BPP) are capable of returning to normal the hyperinsulinaemia, hyperglycaemia and weight gain of New Zealand obese mice. The lag glucose tolerance also becomes indistinguishable from normal. The mechanism whereby these polypeptides cause reversion is not known. Reversion can ...

The syndrome of Shwachman is characterized by pancreatic insufficiency and bone marrow dysfunction, usually manifesting itself as neutropenia. The pancreas shows replacement of the exocrine glands by adipose tissue; sweat electrolytes are normal. A 23-year-old male who was known to suffer from neutropenia and pancreatic dysfunction from early childhood, presented ...

Premature activation of proteolytic zymogens (trypsinogen, chymotrypsinogen) as an early step in the pathogenesis of exocrine pancreatic insufficency (EPI) syndrome in CBA/J mice was investigated in electrophoresed pancreatic homogenates. Polyacrylamide gels containing extracts from control pancreas required prior activation of trypsinogen and chymotrypsinogen (with exogenously added enterokinase and trypsin, respectively) ...

A case is reported of a cystic craniopharyngioma involving the floor and walls of the third ventricle. Pronounced anterograde and retrograde amnesia were documented preoperatively by formal testing. Rapid improvement in both new learning capacity and remote memory occurred after percutaneous twist drill drainage of the cystic portion of the ...

1. Plasma VIP immunoreactivity is always diagnostically raised in patients with pancreatic tumour causing the Verner-Morrison syndrome. 2. Human tumour VIP is physico-chemically similar to porcine VIP. 3. The only other situation in which plasma VIP is very elevated is in patients with ganglioneuroblastomas associated with diarrhoea. 4. VIP is ...

Lesions induced in each of 9 young colostrum-deprived calves closely resembled lesions seen in naturally occurring "weak calf syndrome" of eastern Idaho and southwestern Montana. The disease was experimentally induced by intravenous injection of bovine adenovirus type 5 that had been isolated from a calf with weak calf syndrome...

Immunologic evaluation of a patient with pancreatitis, subcutaneous fat necrosis, pleuritis, pericarditis and synovitis is presented. The previously recognized syndrome of pancreatic disease, subcutaneous fat necrosis and arthritis is reviewed. Based on analysis of all the cases described in the English language literature it is suggested that this syndrome be ...

The distribution of carbonic anhydrase in the exocrine pancreas of the rat has been examined during the first 3 weeks after duct ligation. The normal pattern of positive reaction in ducts, centroacinar cells and capillaries changed, by the end of the first week, to one in which all the cells ...

A method is described which permits rapid phenotypic diagnosis of the Lesch-Nyhan heterozygote by direct assay of hypoxanthine guanine phosphori-bosyltransferase activity in single hair follicles obtained from the scalp.

Over a two-month period 30 patients were admitted to hospital following stings of the scorpion of Trinidad, the Tityus trinitatis. In 24 cases acute pancreatitis developed soon after the sting, but in nine of these no abdominal pain occurred. All the patients made an uneventful recovery. Although such complications have ...

Methods for bio-assay of secretin-like humoral agents in both cat and dog are described. Bio-assay of tumour extracts and of plasma from patients with the pancreatic choleraic syndrome are described. The first patient was found to have choleretic and secretinlike activity in an extract of her pancreatic islet cell tumour ...

An individual who has cystic fibrosis (CF) may suffer from gastrointestinal problems related to inadequately controlled intestinal absorption secondary to the pancreatic insufficiency. These include neonatal meconium ileus, distal intestinal obstruction syndrome (DIOS), constipation and acquired megacolon, rectal prolapse and rarely pancreatitis. If the intestinal malabsorption is well controlled with ...

Gastroduodenostomy after gastric resection is a procedure which can be readily performed if the short gastric vessels are first divided. It makes for a more physiological restoration of the gastrointestinal tract than is accomplished with gastrojejunostomy and permits proper admixture of the food with the bile and pancreatic enzymes. It ...
