Management of patient with hepatic disorder in dental office (hepatitis, alco...Shankar Hemam
The document provides information on managing dental patients with hepatic disorders such as hepatitis and alcoholic liver disease. It discusses the various types of hepatitis (A, B, C, D, E), their causes, symptoms, and medical management. For dental management, it emphasizes identifying potential hepatitis carriers, minimizing aerosols for infected patients, using isolation techniques, and consulting physicians on medication and bleeding risks. The liver's role in metabolism requires special consideration of drugs and procedures for patients with hepatic impairment.
Chronic hepatitis is defined as ongoing liver inflammation lasting over 6 months. It is commonly caused by hepatitis B, C, or a combination. Clinical features include fatigue, loss of appetite, jaundice, and elevated liver enzymes. On microscopy, chronic hepatitis shows piecemeal necrosis around the portal tract, interface hepatitis between liver lobes, and bridging fibrosis linking different areas. The activity of chronic hepatitis is assessed based on necrosis, inflammation, and fibrosis levels, and used to classify it as persistent, lobular, or active hepatitis. Carriers have no symptoms but can transmit hepatitis viruses through detectable surface antigens in their blood.
Hepatitis (viral and non viral types) ppt slidesharesonam
Hepatitis is inflammation of the liver tissue. Some people or animals with hepatitis have no symptoms, whereas others develop yellow discoloration of the skin and whites of the eyes (jaundice), poor appetite, vomiting, tiredness, abdominal pain, and diarrhea. Hepatitis is acute if it resolves within six months, and chronic if it lasts longer than six months.
Chronic hepatitis is broadly defined as liver inflammation that lasts at least 6 months and can have various etiologies. The document discusses chronic hepatitis caused by hepatitis B and C viruses, which can lead to complications like liver cirrhosis and cancer over time. Autoimmune hepatitis and drug or toxic-induced chronic liver disease are also examined, along with their diagnostic features and treatment approaches.
Chronic hepatitis is characterized by a persistent inflammatory process in the liver lasting over 6 months. It is classified into three types based on histological features: chronic active hepatitis marked by necrosis and fibrosis carrying the worst prognosis; chronic persistent hepatitis with portal inflammation but no significant necrosis; and chronic lobular hepatitis involving hepatocyte apoptosis. Chronic hepatitis can be caused by viruses, metabolic disorders, drugs, or autoimmune conditions. Patients may be asymptomatic or experience fatigue, abdominal pain, jaundice, or liver abnormalities. Liver biopsy examines inflammation grade and fibrosis stage and helps establish etiology through immunological testing.
This document discusses steatohepatitis (fatty liver disease), which can be alcoholic or non-alcoholic in origin and can present as mild hepatitis. It also discusses acute autoimmune hepatitis (AIH), noting that it accounts for a small percentage of liver transplants. AIH has a severe natural history if untreated and various genetic and environmental triggers are discussed. Simplified diagnostic criteria for AIH include autoantibodies, elevated IgG, histological findings, and exclusion of viral hepatitis. The three main types of AIH are described based on demographics, autoantibodies, associated conditions, and severity.
1) An 18-year-old female presented with fever, malaise, nausea, vomiting and right upper quadrant pain for 3 days. Laboratory tests showed elevated bilirubin and ALT levels consistent with acute hepatitis.
2) Acute hepatitis can be caused by various viral, drug-induced, autoimmune and metabolic etiologies. The document discusses the pathogenesis and typical symptoms of acute hepatitis such as anorexia, nausea and jaundice.
3) Management of acute hepatitis is generally supportive with maintenance of nutrition, fluids and electrolytes. Severe cases may require admission and treatment of complications like hepatic encephalopathy. Most viral cases of acute hepatitis resolve on their own within a few months.
Chronic viral hepatitis can be caused by hepatitis B virus (HBV), hepatitis C virus (HCV), or hepatitis D virus (HDV). HBV is responsible for 60-80% of hepatocellular carcinoma worldwide. HCV infection is the most common chronic blood-borne infection and a leading cause of cirrhosis and liver cancer. HDV requires HBV coinfection and can cause a more severe form of hepatitis. Treatment for chronic HBV and HCV infection involves antiviral medications like interferons, nucleoside analogs, and nucleotide analogs to achieve viral suppression and prevent disease progression.
This document discusses acute hepatitis. It begins by defining the liver and explaining that hepatitis can be either acute or chronic, with acute hepatitis having an abrupt onset. It then classifies acute hepatitis etiologically into viral and non-viral types. Viral acute hepatitis may be caused by several viruses including HAV, HBV, HCV, HEV, and HDV. Significant elevations of certain proteins and acute phase reactants can indicate more severe acute hepatitis. Liver biopsy is controversial for diagnosing acute hepatitis due to its invasiveness but may be needed to guide treatment decisions. Complications of acute hepatitis are also discussed.
This document discusses hepatitis and liver cirrhosis. It defines hepatitis as inflammation of the liver that can result from drugs, poisons, or infections. The main causes of hepatitis are viral strains A-E and G, bacteria, alcohol, drugs, and autoimmune disorders. Chronic liver disease includes chronic hepatitis and cirrhosis. Cirrhosis occurs when liver tissue is damaged and replaced by scar tissue, which can lead to life-threatening complications like bleeding and organ failure. The document provides details on each type of viral hepatitis and guidelines for safely treating dental patients with liver disease or hepatitis to prevent further infection.
This document provides information on acute viral hepatitis. It defines different types of hepatitis including acute, chronic, fulminant and cirrhosis. It describes the clinical stages and features of acute viral hepatitis including the incubation period, prodromal phase, icteric phase and recovery phase. It also discusses the investigations conducted to diagnose acute viral hepatitis including liver function tests and identification of viruses through antibodies or nucleic acid testing. The management of acute viral hepatitis is described as mainly supportive without specific treatment, though hospitalization may be needed in severe cases. Complications like chronic hepatitis, fulminant hepatitis and prophylaxis through vaccines and hygiene are also summarized.
Hepatitis is inflammation of the liver that can be caused by viruses, bacteria, toxins, and drugs. There are several types of hepatitis defined by their causes, which include viral types A, B, C, D, and E transmitted by fecal-oral, blood, or sexual contact; alcoholic hepatitis caused by heavy alcohol use; and toxic hepatitis due to toxins, drugs, or chemicals. Diagnosis involves liver enzyme and function tests to determine the presence and extent of liver damage. Treatment depends on the type but may include antiviral medications, immune system modulators, and avoiding further liver damage.
Viral hepatitis can be acute or chronic depending on whether symptoms last less than or more than six months. The main causes are infectious hepatitis viruses like hepatitis A, B, C, D, and E. Hepatitis A spreads through the fecal-oral route while hepatitis B, C, and D spread through blood and body fluids. Many people infected with hepatitis B or C do not show symptoms but can develop chronic liver disease and cancer over time. Vaccines exist for hepatitis A and B but not for C, D, and E. Treatment focuses on managing symptoms for acute cases and antiviral drugs for chronic cases.
Aasld guidelines for diagnosis & treatment of chronic hepatitis bsreejith246
- The AASLD guidelines provide recommendations for the diagnosis and treatment of chronic hepatitis B in adults and children. They analyzed literature using a GRADE approach to determine the quality of evidence and strength of recommendations.
- The guidelines address whom to treat, how long to treat, preferred antiviral regimens, management of treatment failure or resistance, and special populations like pregnancy and cirrhosis. Key recommendations include treating immune active CHB with antivirals and considering indefinite treatment for HBeAg-negative or cirrhotic patients.
Chronic hepatitis is a group of chronic inflammatory diseases of the liver characterized by hepatocyte inflammation, necrosis and dystrophy while maintaining the lobular structure. More than 70% are asymptomatic. About 350-400 million people have chronic hepatitis B worldwide and around 180 million have hepatitis C. Treatment depends on the etiology and includes antiviral drugs and interferons with the goal of suppressing viral replication.
This document discusses various vascular diseases of the liver. It covers topics such as ischemic hepatitis, Budd-Chiari syndrome, congestive hepatopathy, sinusoidal obstruction syndrome, and extrahepatic portal vein obstruction. The key points are that these diseases involve primary alterations in the blood or lymphatic vessels of the liver or changes secondary to other conditions. They can result in liver ischemia, obstruction of vessels, or other vascular abnormalities. The diagnosis and treatment of each condition is also outlined.
Chronic hepatitis in children refers to ongoing liver inflammation lasting over six months. It is most commonly caused by hepatitis B or C viruses. For hepatitis B, infection acquired during birth or early childhood usually results in chronic infection. Treatment aims to reduce cirrhosis and liver cancer risks by eliminating HBeAg. For hepatitis C, the most important transmission mode in children is vertical from mother to child. Both viruses can cause asymptomatic mild illness initially but may progress to chronic liver disease.
Viral hepatitis is an inflammation of the liver caused by infectious hepatitis viruses. There are 5 main hepatitis viruses - Hepatitis A, B, C, D, and E. Hepatitis A is transmitted through the fecal-oral route while Hepatitis B can be transmitted sexually or parenterally. Hepatitis C is commonly spread through intravenous drug use or blood transfusions. Hepatitis D only infects those also infected with Hepatitis B. Hepatitis E is also spread through the fecal-oral route. Acute viral hepatitis presents with fatigue, nausea, abdominal pain and jaundice while chronic hepatitis from some viruses can lead to cirrhosis or liver cancer over many years.

Hepatitis is an inflammation of the liver that can be caused by viruses or toxins. There are five main types of viral hepatitis: Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, and Hepatitis E. Hepatitis A is caused by the Hepatitis A virus and spreads through the fecal-oral route, causing an acute self-limiting infection. Hepatitis B is caused by the Hepatitis B virus and spreads through blood and body fluids, causing both acute and chronic infections. While there is no treatment for Hepatitis A, Hepatitis B can be prevented through vaccination.
The document provides information about Hepatitis A and Hepatitis B viruses including:
1. Hepatitis A virus is transmitted through the fecal-oral route while Hepatitis B can be transmitted through contact with infected blood or bodily fluids.
2. Hepatitis A infection causes an acute illness that does not lead to chronic infection or liver disease. Hepatitis B can result in either an acute or chronic infection, with chronic infection putting one at risk of serious liver diseases.
3. Diagnosis of Hepatitis A is usually based on detecting IgM antibodies in serum while Hepatitis B involves blood tests to detect hepatitis B surface antigen and specific antibodies.
Chronic viral hepatitis can be caused by hepatitis B or hepatitis C virus infections lasting longer than 6 months. It often presents with non-specific symptoms but can lead to serious complications affecting the liver and other organs. Treatment aims to suppress viral replication through medications like PEG-interferon or oral antivirals in order to prevent progression to cirrhosis or liver cancer. Chronic hepatitis requires long-term management as patients may experience ongoing liver inflammation and disease progression over their lifetime.
Chronic viral hepatitis can be caused by hepatitis B or hepatitis C virus infections lasting more than 6 months. It often presents with non-specific symptoms but can lead to serious complications affecting the liver and other organs. Treatment aims to suppress viral replication through medications like interferons or oral antivirals in order to prevent progression to cirrhosis or liver cancer. Accurate diagnosis involves identifying viral markers in the blood and seeing inflammatory changes on liver biopsy.
A 31-year-old female presented with loss of appetite, nausea, vomiting, fatigue, stomach pain, and hepatomegaly. Upon examination, the doctor noticed yellowing of her skin and eyes. Blood tests were positive for hepatitis C. Hepatitis C is a disease of the liver caused by the hepatitis C virus, which can lead to chronic infection in 60-70% of cases and cause cirrhosis in a small percentage over time. The patient's symptoms and blood test results indicate she has hepatitis C infection.
Infective Hepatitis can be acute or chronic depending on duration. Acute hepatitis may resolve on its own or progress to chronic hepatitis or rarely acute liver failure. Chronic hepatitis can progress to cirrhosis, liver failure, or cancer. Hepatitis is commonly caused by viral infections including hepatitis A, B, C, D, and E. Hepatitis A spreads through the fecal-oral route while hepatitis B, C, and D spread through blood and bodily fluids. Symptoms vary but often include fatigue, jaundice, abdominal pain, and nausea. Treatment depends on the type of hepatitis.

Chronic hepatitis in children can be caused by viral infections like hepatitis B and C, autoimmune disorders, drug reactions, and metabolic diseases. Hepatitis B often becomes chronic if contracted as a newborn. It progresses through immune tolerant, immune active, and inactive carrier phases. Hepatitis C poses a high risk of chronicity in children. Autoimmune hepatitis involves liver inflammation from a misdirected immune response. Common drugs that can cause chronic liver injury include anti-tubercular and anticonvulsant medications. Metabolic diseases such as Wilson's disease and nonalcoholic steatohepatitis account for a significant percentage of chronic liver disease in children. Treatment depends on the underlying cause and may include antiviral therapy,
The document discusses hepatitis, which is inflammation of the liver. It outlines the various causes of hepatitis including viruses, chemicals, drugs, and autoimmune diseases. It focuses on the different types of viral hepatitis (A, B, C, D, E), their symptoms, modes of transmission, risks, and ability to cause both acute and chronic conditions. Hepatitis B and C are particularly discussed as leading causes of chronic liver disease and liver cancer worldwide.
A 55-year-old male presented with complaints of right upper quadrant pain, fatigue, fever, and weight loss over the past month. He has a history of IV drug use. Laboratory tests showed elevated liver enzymes. The patient is diagnosed with hepatitis C based on his risk factors and lab results. Hepatitis C is a viral infection that attacks the liver, often transmitted through blood or drug use. It can lead to both acute and chronic liver inflammation and damage over many years.
Hepatitis C virus (HCV) infection is the most common chronic bloodborne infection in the United States, with approximately 3.2 million people chronically infected. HCV accounts for 40% of chronic liver disease and is the most common cause of liver transplant in the country. Genotype 1 is the most prevalent worldwide, accounting for 70% of HCV cases in the United States. HCV transmission occurs primarily through blood exposures like transfusions, injection drug use, and medical equipment reuse. The average incubation period is 6-7 weeks, though 90% of infected individuals test antibody positive within 5 months.

This document provides information about hepatitis, including its definition, causes, history, clinical features, and treatments. The main causes of hepatitis include viral hepatitis from hepatotropic viruses like HAV, HBV, HCV, HDV, and HEV, as well as non-infectious causes like alcohol, drugs, autoimmune reactions, and metabolic disorders. The document describes the characteristics of different viral hepatitises and recommendations for evaluation, prevention, and treatment of acute and chronic hepatitis.
Hepatitis A is the most common cause of viral hepatitis in children, accounting for 40-60% of cases. It is generally a self-limiting disease that does not result in chronic liver disease or complications in most cases. Hepatitis B, C, D are responsible for transfusion-related hepatitis and Hepatitis A and E are often waterborne infections. While Hepatitis A causes an acute, self-limiting infection, Hepatitis B can result in chronic infection and acute liver failure. Hepatitis C often presents asymptomatically but frequently leads to chronic infection. Vaccines exist to prevent Hepatitis A and B but there is no vaccine for Hepatitis C, D or E.
