Spatial and temporal dynamics of innervation during the development of fetal human pancreas.
2008
The delineation of pancreatic nerve innervations during fetal life may contribute to our understanding of pancreatic pain modalities after birth. The aim of this study was to characterize the spatial and temporal distribution of nerve structures in the human pancreas throughout gestation. Computer-based image morphometry with piecewise polynomial interpolation analysis was performed to quantify nervous structures in the head, body and tail of the pancreas. Nerve structures were detected by automatic immunostaining techniques using a polyclonal antibody against two S-100 proteins that reacts strongly with human S100A and B that are detected in Schwann cells. Immunoreactivity was found in the…
Diabetes screening by telecentric digital holographic microscopy
2015
Diabetes is currently the world's fastest growing chronic disease and it is caused by deficient production of insulin by the endocrine pancreas or by abnormal insulin action in peripheral tissues. This results in persistent hyperglycaemia that over time may produce chronic diabetic complications. Determination of glycated haemoglobin level is currently the gold standard method to evaluate and control sustained hyperglycaemia in diabetic people. This measurement is currently made by high-performance liquid chromatography, which is a complex chemical process that requires the extraction of blood from the antecubital vein. To reduce the complexity of that measurement, we propose a fully-optica…
Pancreas and Cystic Fibrosis: The Implications of Increased Survival in Cystic Fibrosis
2007
Background: In acute pancreatitis (AP), pancreatic necrosis (PN) is an important local complication that can be identified by means of contrast-enhanced computed tomography (CECT).
Laser fragmentation of pancreatic duct stones using a rhodamine laser with an automatic stone-tissue detection system. Basic in-vitro studies
1997
OBJECTIVES The aim of our study was to examine the suitability of a rhodamine 6G laser with an integrated stone-tissue detection system (STDS) for fragmenting pancreatic stones. METHODS A total of 64 pancreatic duct stones were measured for weight, diameter, main chemical components and in some cases for their computerized tomography density. Recognition of all stones was checked with the standard STDS or a prototype version. Number of fragmentation pulses, total fragmentation energies and correlation with the individual stone parameters were determined. The quality of the tissue-detection mode was evaluated in postmortem pancreata. RESULTS The standard STDS detected only 45% of the pancrea…
Inflammatory and tumor-like lesions of the pancreas
2020
Summary Inflammatory/tumor-like lesions of the pancreas represent a heterogeneous group of diseases that can variably involve the pancreatic gland determining different signs and symptoms. In the category of inflammatory/tumor-like lesions of the pancreas, the most important entities are represented by chronic pancreatitis, which includes alcoholic, obstructive and hereditary pancreatitis, paraduodenal (groove) pancreatitis, autoimmune pancreatitis, lymphoepithelial cyst, pancreatic hamartoma and intrapancreatic accessory spleen. An in-depth knowledge of such diseases is essential, since they can cause severe morbidity and may represent a potential life-threatening risk for patients. Furthe…
Pancreatitis autoinmune: pseudotumor inflamatorio, afectación multifocal, hipertensión portal y evolución a largo plazo
2008
Autoimmune pancreatitis is a recently characterized disease that still constitutes a diagnostic challenge, especially regarding differential diagnosis from neoplasia. Long-term outcome is poorly known. We herein report a case of a patient with autoimmune pancreatitis and 14 years of follow-up, and show its clinical, biochemical, and morphological characteristics. A 54-year-old female presented with obstructive jaundice and abdominal tenderness, as well as a mass at the pancreatic head on a CT scan, suggestive of pancreatic neoplasia. Surgery showed an increase of the whole pancreas, malignancy was intraoperatively ruled out, and a cholecystectomy and choledochoduodenostomy were carried out.…
Ultrasonic demonstration of small pancreatic islet cell tumors.
1982
In three patients real-time sonography successfully localized small pancreatic islet cell tumors measuring 7, 8, and 17 mm in size. Ultrasound is suggested as the initial radiologic examination for localization of endocrine pancreatic tumors. If ultrasound is negative or equivocal, computerized tomography, arteriography, and pancreatic venous sampling are indicated.
Quiste broncogénico de localización excepcional que simula una tumoración pancreática
2010
We report a 37-year woman with a history of acute cholangitis in whom a bronchogenic cyst was misdiagnosed as a pancreatic neoplasm on the basis of the clinical and radiological findings. Infradiaphragmatic bronchogenic cysts are rare and can sometimes mimic a pancreatic carcinoma.
Determination of Human Granulocyte Elastase by the Immunoactivation Method on the Hitachi® 717 Automated Analyser
1991
This paper describes a fully mechanized homogeneous immunoassay using the immunoactivation method for the rapid and specific determination of human granulocyte elastase (EC 3.4.21.37) in plasma. The method uses anti-elastase antibody fragments from sheep, conjugated to horseradish peroxidase. These enzyme-antibody conjugates bind to the elastase-alpha 1-proteinase inhibitor complex present in plasma. A separate sample blank with non-specific sheep antibody fragments conjugated to horseradish peroxidase corrects for errors introduced by the sample matrix. Measurements were performed with the clinical chemistry analyser Hitachi 717. A single determination can be performed in 10 min, requiring…
PO-0359 How To Select The Sweat Test Candidate. 10 Years Of Experience In Screening For Cystic Fibrosis In Children
2014
Background Sweat test (ST) remains gold standard in cystic fibrosis (CF) diagnosis. Alarm symptoms are age-related. Aims Retrospective review of cases subjected to ST. Methods Patients were selected by paediatricians, neonatologists, surgeons, based on suggestive symptoms, personal (PH) and familial history (FH). Inclusion criteria: for 0–1 month age group, patients with PH of atelectasis, meconium ileus, intussusception; 1–12 months, recurrent wheezing (RW), failure to thrive (FTT); 1–5 years, previous group symptoms, plus chronic cough/diarrhoea; >5 years, 1–5 years symptoms, plus recurrent pancreatitis/sinusitis. For all age, patients with PH of salty taste of sweat (STS), salt wasting s…
