Acute pancreatitis (AP) is a sudden inflammation of the pancreas.Causes include a gallstone impacted in the common bile duct or the pancreatic duct, heavy alcohol use, systemic disease, trauma, elevated calcium levels, hypertriglyceridemia (with triglycerides usually being very elevated, over 1000 mg/dL), certain medications, hereditary causes and, in children, mumps.
Smoking increases the risk of both acute and chronic pancreatitis. [3] [4] Diagnosis of acute pancreatitis is based on a threefold increase in the blood of either amylase or lipase. [1] In chronic pancreatitis, these tests may be normal. [1] Medical imaging such as ultrasound and CT scan may also be useful. [1] Acute pancreatitis is usually ...
Computed tomography (CT) findings in AIP include a diffusely enlarged hypodense pancreas or a focal mass that may be mistaken for a pancreatic malignancy. [8] A low-density, capsule-like rim on CT (possibly corresponding to an inflammatory process involving peripancreatic tissues) is thought to be an additional characteristic feature (thus the ...
Pancreatic abscess is a late complication of acute necrotizing pancreatitis, occurring more than 4 weeks after the initial attack. A pancreatic abscess is a collection of pus resulting from tissue necrosis, liquefaction, and infection. It is estimated that approximately 3% of the patients with acute pancreatitis will develop an abscess. [1]
COVID-19 can be identified with higher precision using CT than with RT-PCR. [93] Subpleural dominance, crazy paving, and consolidation may develop as the disease evolves. [92] [94] Chest CT scans and chest x-rays are not recommended for diagnosing COVID-19. Radiologic findings in COVID-19 lack specificity. [92] [95]
In pancreatitis, enzymes of the exocrine pancreas damage the structure and tissue of the pancreas. Detection of some of these enzymes, such as amylase and lipase in the blood, along with symptoms and findings on medical imaging such as ultrasound or a CT scan, are often used to indicate that a
The rare simultaneous occurrence of thrombocytopenia (low blood platelets) with blood clots after vaccination raised the original concern about this condition. [citation needed] In many cases where acute thrombosis and thrombocytopenia have been found together after COVID‑19 vaccination, an antibody against platelet factor 4 has been ...
Scanning electron micrograph of SARS virions. Severe acute respiratory syndrome (SARS) is the disease caused by SARS-CoV-1. It causes an often severe illness and is marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms, [13] mainly cough, dyspnea, and pneumonia.
