Biliary Pancreatitis: Endoscopic Diagnostic and Therapeutic Techniques
1987
Acute pancreatitis constitutes one of the most hazardous emergencies in clinical gastroenterology. Although the diagnosis “biliary pancreatitis” is often used in clinical practice for patients presenting with concrements in the biliary tree or impacted in the papillary orifice [17, 32], the common phrase “biliary pancreatitis” has not so far been exactly defined. Patients with cholecystolithiasis may be included in this group, as well as patients with dysfunction of the sphincter of Oddi. Some authors have reported that juxtapapillary diverticula increase the risk for development of biliary pancreatitis [28].
Expression of HIP/PAP mRNA in Human Hepatoma Cell Lines
2002
The present study attempts to shed more light on the role of hepatocarcinoma-intestine-pancreas/pancreatic associated protein (HIP/PAP) in hepatoma cells. We initially examined, by reverse transcription-polymerase chain reaction (RT-PCR), the HIP/PAP transcripts present in human hepatoma cell lines of different origins and with different grades of differentiation and genetic profiles. We also used DNA sequencing analysis to investigate the structure of the HIP/PAP gene. Further investigation is necessary to define the role of HIP/PAP during the development of human hepatocellular carcinoma and to ascertain whether the use of different transcripts is helpful in regulating HIP/PAP expression …
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).
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.…
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…
Pentoxifylline and Oxypurinol: Potential Drugs to Prevent the “Cytokine Release (Storm) Syndrome” Caused by SARS-CoV-2?
2020
Background: COVID-19, caused by SARS-CoV-2, is a potentially lethal, rapidly-expanding pandemic and many efforts are being carried out worldwide to understand and control the disease. COVID-19 patients may display a cytokine release syndrome, which causes severe lung inflammation, leading, in many instances, to death. Objective: This paper is intended to explore the possibilities of controlling the COVID-19-associated hyperinflammation by using licensed drugs with anti-inflammatory effects. Hypothesis: We have previously described that pentoxifylline alone, or in combination with oxypurinol, reduces the systemic inflammation caused by experimentally-induced pancreatitis in rats. Pentoxifyl…
Co-administration of pentoxifylline and thiopental causes death by acute pulmonary oedema in rats
2006
Background and purpose: Pentoxifylline exhibits rheological properties that improve microvascular flow and it is widely used in vascular perfusion disorders. It also exhibits marked anti-inflammatory properties by inhibiting tumour necrosis factor a production. Thiopental is one of the most widely used drugs for rapid induction of anaesthesia. During experimental studies on the treatment of acute pancreatitis, we observed that when pentoxifylline was administered after anaesthesia with thiopental, most of the rats exhibited dyspnea, signs of pulmonary oedema and died. The aim of the work described here was to investigate the cause of the unexpected toxic effect of the combined treatment wit…
Role of Redox Signaling, Protein Phosphatases and Histone Acetylation in the Inflammatory Cascade in Acute Pancreatitis: Therapeutic Implications
2010
Acute pancreatitis starts as a local inflammation of the pancreatic tissue but often leads to the systemic inflammatory response syndrome and death by multiple organ failure. Pro-inflammatory cytokines, particularly TNF-alpha and Il-1beta, play a pivotal role together with oxidative stress and glutathione depletion in the inflammatory response in this disease. Most inflammatory mediators act through mitogen activated protein kinases and nuclear factor kB. Nevertheless, elucidation of the precise mechanisms involved in activation and attenuation phases of the inflammatory cascade is still underway. Redox signaling mediated by inactivation of protein phosphatases and histone acetylation trigg…
Disulfide stress: a novel type of oxidative stress in acute pancreatitis.
2013
Glutathione oxidation and protein glutathionylation are considered hallmarks of oxidative stress in cells because they reflect thiol redox status in proteins. Our aims were to analyze the redox status of thiols and to identify mixed disulfides and targets of redox signaling in pancreas in experimental acute pancreatitis as a model of acute inflammation associated with glutathione depletion. Glutathione depletion in pancreas in acute pancreatitis is not associated with any increase in oxidized glutathione levels or protein glutathionylation. Cystine and homocystine levels as well as protein cysteinylation and γ-glutamyl cysteinylation markedly rose in pancreas after induction of pancreatitis…
