Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

1.7K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Hypothesis Test for Test of Independence

6.8K
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis02:29

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis

12.3K
Overview
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

1.0K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Gastritis III: Clinical Manifestations and Management

996
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Acid Halides to Esters: Alcoholysis01:12

Acid Halides to Esters: Alcoholysis

3.7K
Alcoholysis is a nucleophilic acyl substitution reaction in which an alcohol functions as a nucleophile. Acid halides react with alcohol to produce esters. The mechanism proceeds in three steps:

Area of Science:

  • Hepatology
  • Gastroenterology
  • Internal Medicine

Background:

  • Alcoholic hepatitis is a frequent and severe liver condition in Mexico, characterized by acute-on-chronic liver failure and high mortality.
  • Alcohol-related liver disease encompasses a spectrum from steatosis to cirrhosis, with severe alcoholic hepatitis defined by specific clinical scores.

Framework:

  • The first Mexican consensus on alcoholic hepatitis was developed by a multidisciplinary team using the Delphi method.
  • This consensus resulted in 37 evidence-based recommendations for managing alcoholic hepatitis.

Implementation:

  • Diagnosis guidance includes clinical signs like leukocytosis, hyperbilirubinemia, and specific AST/ALT ratios, as no specific biomarker exists.
  • Key treatments involve alcohol abstinence and nutritional support, with steroids indicated for severe cases to reduce mortality.

Implications:

  • Steroids are effective in reducing 28-day mortality for severe alcoholic hepatitis.
  • Liver transplantation is the sole life-saving option for non-responders to steroid therapy.
  • Adjuvant therapies like N-acetylcysteine and granulocyte-colony stimulating factor may improve patient survival.
