Macroamylasaemia after treatment with hydroxyethyl starch
1977
After infusion of 500 ml of 6% hydroxyethyl starch into fifty-four patients an increase of serum amylase was observed which in fifty-one cases exceeded the upper limit of normal (190 U/l). In most cases serum amylase reached twice the basal value. Renal function influenced the duration of the increase in serum amylase, but not the maximum increase (201+/-15 U/l; mean+/-SEM). In patients with advanced renal failure (glomerular filtration rate (GFR) = 2-10 ml/min) serum amylase was still markedly elevated after 72 h (298+/-24 U/l; mean+/-SEM). In patients with normal renal function (GFR greater than 90 ml/min) serum amylase decreased to 183+/-40 U/l (mean+/-SEM) within 72 h without reaching b…
Exocrine Pancreatic Function and Fat Malabsorption in Human Immunodeficiency Virus-Infected Patients
1999
BACKGROUND: Nutrients malabsorption frequently occurs in human immunodeficiency virus (HIV)-infected patients, but very few studies have investigated exocrine pancreatic digestive capacity in these patients. We therefore evaluated the frequency of exocrine pancreatic impairment and its eventual relation with fat malabsorption in HIV-infected patients. METHODS: Thirty-five HIV-infected patients (30 male, 5 female: mean age +/- standard deviation, 33.6 +/- 7.2 years) and 51 sex- and age-matched controls without gastroenterologic diseases were studied. In all subjects fecal elastase 1 (EL-1) was assayed, and fecal fat excretion was evaluated with the steatocrit test. RESULTS: Nineteen of 35 (5…
Second-line chemotherapy in advanced pancreatic carcinoma: a multicenter survey of the Gruppo Oncologico Italia Meridionale on the activity and safet…
2007
Background: In daily clinical practice second-line chemotherapy (SLCT) is frequently given to patients with advanced pancreatic cancer failing gemcitabine-based first-line chemotherapy without solid scientific support. Patients and methods: A retrospective survey was carried out including 42 patients. Patients received standard FOLFOX4 regimen biweekly until progression or unacceptable toxicity. Results: Six partial responses (14%) and 16 stabilizations (38%) were recorded for a tumor growth control rate of 57%. The median time to progression (TtP) was 4 months (range 1–7 months), and median overall survival (OS) was 6.7 months (range 2–9 months). A stabilization of performance status (PS) …
Total pancreatectomy: indications, operative technique, and results: a single centre experience and review of literature.
2010
The aims of this study were to identify the indications to perform a total pancreatectomy and to evaluate the outcome and quality of life of the patient who underwent this operation. A retrospective analysis of a prospective database, regarding all the patients who underwent total pancreatectomy from January 2006 to June 2009, was carried out. Perioperative and outcome data were analyzed in two different groups: ductal adenocarcinoma (group 1) and non-ductal adenocarcinoma (group 2). Twenty (16.9%) total pancreatectomies out of 118 pancreatic resections were performed. Seven (35.0%) patients were affected by ductal adenocarcinoma (group 1) and the remaining 13 (65.0%) by pancreatic diseases…
Are pancreatic calcifications specific for the diagnosis of chronic pancreatitis? A multidetector-row CT analysis
2009
Aim To retrospectively establish the most frequently encountered diagnoses in patients with pancreatic calcifications and to investigate whether the association of certain findings could be helpful for diagnosis. Materials and methods One hundred and three patients were included in the study. The location and distribution of calcifications; presence, nature, and enhancement pattern of pancreatic lesions; pancreatic atrophy and ductal dilatation were recorded. Differences between patients with chronic pancreatitis and patients with other entities were compared by using Fisher's exact test. Results Patients had chronic pancreatitis ( n =70), neuroendocrine tumours ( n =14), intraductal papill…
The Applicability of a Checklist for the Diagnosis and Treatment of Exocrine Pancreatic Insufficiency: Results of the Italian Exocrine Pancreatic Ins…
2020
Objective To evaluate a rapid checklist capable of identifying exocrine pancreatic insufficiency in outpatients. Methods Prospective observational study of a multicenter cohort. Results One hundred and two patients were enrolled; 61.8% of the patients had medically-treated benign or malignant pancreatic disease, and 38.2% had a pancreatic resection. Visual examination of the feces was evaluated in 84 patients and it was related to steatorrhea in 51 patients (50.0%). Receiver operating characteristic curves were evaluated for each symptom or clinical sign and four of them (ie, increase in daily bowel movements, number of bowel movements, fatty stools, >10% weight loss) had a satisfactory …
PANCREATIC CARCINOMA VERSUS CHRONIC FOCAL PANCREATITIS: CONTRAST-ENHANCED POWER DOPPLER ULTRASONOGRAPHY FINDINGS
2005
Background: We assessed the potential usefulness of contrast-enhanced power Doppler ultrasonography (US) for differentiating pancreatic carcinoma from chronic focal pancreatitis. Methods: Twenty-six consecutive patients with ductal carcinoma (n=16) and chronic focal pancreatitis (n=10) underwent power Doppler US examinations before and after intravenous injection of an air-based contrast agent (Levovist, Schering, Berlin, Germany). Final diagnosis was obtained by surgery in all patients. The following parameters before and after intravenous administration of contrast agent were evaluated for each lesion: number, morphology and course of the vessels within the lesion and time to maximum dete…
Pancreatic enzymes in chronic renal failure and transplant patients.
1992
The aim of the present study was to determine the frequency and degree of elevated serum levels of Total Amylase (TA), Pancreatic Amylase (PA), and Lipase (L) activity in patients with chronic renal failure (CRF) on conservative therapy; CRF on periodical hemodialysis (HD); in renal transplant (RT) and in a control Group (C). Mean values were significantly higher in all groups than Group C for TA (p < 0.005), PA (p < 0.0001) and L (p < 0.0001). A statistically significant correlation was found between TA and L vs creatininemia values in CRF patients, but only up to a certain level (creatininemia < 6 mg %) (p < 0.03 and p < 0.05), above which there was no correlation. The enzyme most frequen…
Acute extrahepatic infectious or inflammatory diseases are a cause of transient mosaic pattern on CT and MR imaging related to sinusoidal dilatation …
2015
To report the association of a mosaic enhancement pattern on contrast-enhanced CT or MR imaging and hepatic sinusoidal dilatation (SD) with acute inflammatory conditions affecting extrahepatic organs. From 2007 to 2012, patients with acute inflammatory diseases who underwent contrast-enhanced CT and/or MRI of the liver with a mosaic enhancement pattern were selected. Clinico-biological and other imaging features were collected at diagnosis and during follow-up. Sixteen patients were included (15 women, median age 27 years; range 18–68). Five women (33 %) were receiving oral contraceptives. Acute inflammatory diseases included pyelonephritis (n = 10), pancreatitis (n = 2), pneumonia (n = 1),…
Recent Trends in Survival of Patients With Pancreatic Cancer in Germany and the United States
2016
Objectives Survival improvement for pancreatic cancer has not been observed in the last 4 decades. We report the most up-to-date population-based relative survival (RS) estimates and recent trends in Germany and the United States. Methods Data for patients diagnosed in 1997 to 2010 and followed up to 2010 were drawn from 12 population-based German cancer registries and the US SEER (Surveillance, Epidemiology and End Results) 13 registries database. Using period analysis, 5-year RS for 2007 to 2010 was derived. Model-based period analysis was used to assess 5-year RS time trends, 2002-2010. Results In total 28,977 (Germany) and 34,793 (United States) patients aged 15 to 74 years were analyze…
