Study Notes
Esophageal Varices and Liver Conditions
- Jaundice, bleeding tendencies, and poor oral hygiene are prevalent in liver cirrhosis patients.
- Hepatotoxic drugs should be avoided; physician consultation is necessary before invasive procedures.
- Liver biopsy is the gold standard for diagnosing cirrhosis; additional tests include CBC, viral serology, clotting studies, albumin, platelets, and bilirubin.
- Endoscopy is utilized to assess esophageal varices.
- Cirrhosis is irreversible, but liver transplantation is an option for end-stage patients.
Liver Cancer (Hepatocellular Carcinoma)
- Malignant liver tumors are among the most common globally.
- Major risk factors include chronic hepatitis B and C infections, and cirrhosis.
- Symptoms often present with abdominal pain, weight loss, jaundice, ascites, and hepatomegaly (male to female ratio: 3:1).
- Oral manifestations may include jaundice; metastasis to oral tissue is rare.
- Diagnosis typically requires liver biopsy, alpha-fetoprotein score, ultrasound, and CT scan.
- Treatment options include surgical resection, liver transplant, chemotherapy, and opiates for pain relief.
Jaundice
- Jaundice is characterized by yellow discoloration of tissues, primarily the skin and sclera, with noticeable effects when bilirubin levels exceed 3 mg/L.
- Three primary causes:
- Prehepatic jaundice (e.g., hereditary spherocytosis, sickle cell disease, G6PD deficiency).
- Hepatic jaundice (e.g., viral hepatitis, drugs like paracetamol, toxins, autoimmune disorders, end-stage liver disease).
- Cholestatic jaundice (e.g., drugs like chlorpromazine, gallstones, cholangitis).
- Symptoms include yellowish skin, abdominal pain, and signs of liver failure such as spider nevi and palmar erythema.
- Diagnosis involves blood tests, liver function tests (LFTs), ultrasound, and CT scans.
- Management focuses on identifying and eliminating the underlying cause of jaundice.
Ascites
- Ascites refers to excess free fluid accumulation in the peritoneal cavity, often linked to liver cirrhosis and cardiac failure.
- Symptoms include abdominal discomfort, increased girth, and potential shortness of breath due to diaphragm compression.
- No unique oral manifestations of ascites exist, but dental considerations should be noted.
- Diagnosis relies on patient history, physical examination, and elevated liver enzymes in blood tests.
Alcoholic Liver Disease (ALD)
- Alcoholic liver disease resulting from excessive alcohol consumption can manifest in three stages:
- Fatty liver—mildest reversible injury.
- Alcoholic hepatitis—marked by hepatocellular damage and symptoms like jaundice and ascites.
- Cirrhosis—characterized by fibrosis and irreversible damage.
- Patients may exhibit signs such as jaundice, ascites, edema, and potential memory deficits.
- Diagnosis involves clinical evaluation and history of alcohol use.
- Dental management includes consultation with physicians, avoiding hepatotoxic drugs, and providing alcohol prevention information.
- Laboratory tests for liver function and bleeding parameters are crucial before surgical procedures.
Learning Objectives
- Understand epidemiology, manifestations, complications, and management of hepatology disorders affecting dental health.
- Develop skills to interpret clinical signs and laboratory investigations related to hepatology disorders.
- Create evidence-based management plans for dental patients with hepatology issues.
- Identify emergency situations and maintain patient homeostasis.
Liver Diseases of Dental Interest
Viral Hepatitis
- General: Inflammation of the liver caused by viruses, can be acute or chronic.
-
Hepatitis A:
- RNA virus, transmitted via fecal-oral route.
- Incubation: 15-50 days; no carrier state; lifelong immunity after infection.
- Prophylaxis includes immunoglobulin and vaccination.
-
Hepatitis B:
- DNA virus, transmitted through blood, sexual contact, and perinatal routes.
- Incubation: 30-180 days; carrier state present.
- Prophylaxis includes Hepatitis B immunoglobulin and vaccination; immunity likely lifelong.
-
Hepatitis C:
- RNA virus, primarily via blood.
- Incubation: 15-160 days; significant carrier state (50-80%).
- No vaccine or prophylaxis available.
-
Hepatitis D:
- Defective RNA virus, requires co-infection with Hepatitis B.
- Incubation: 21-140 days; carrier state exists; no effective prophylaxis.
-
Hepatitis E:
- Defective RNA virus, transmit via fecal-oral route.
- Incubation: 15-64 days; no carrier state; may confer lifelong immunity.
Clinical Features of Viral Hepatitis
- Early symptoms resemble flu (anorexia, fatigue, myalgia).
- Three stages:
- Preicteric: Anorexia, malaise, fever, nausea.
- Icteric: Jaundice, upper quadrant pain, hepatomegaly.
- Posticteric: Jaundice resolves, but hepatomegaly may persist.
Oral Manifestations and Dental Management
- Jaundice visible in oral mucosa during icteric phase.
- All patients considered potentially infectious; standard precautions required.
- Urgent dental treatment only for patients with active hepatitis.
- No hepatotoxic medications for hepatitis patients.
- High-risk patients should be screened for HBsAg prior to treatment.
Alcoholic Liver Disease (ALD)
- Results from excessive alcohol consumption leading to liver damage.
- Classification:
- Fatty Liver: Mild, reversible.
- Alcoholic Hepatitis: Inflammation, jaundice, fever, ascites.
- Cirrhosis: Irreversible fibrosis and nodule formation.
Symptoms and Signs of ALD
- Symptoms: Oedema, jaundice, cognitive impairments, ascites.
- Diagnosis: History, clinical findings, breath tests for alcohol.
- Dental considerations: Consultation required, avoid liver-metabolized drugs, address bleeding risks.
Liver Cirrhosis
- Chronic liver disease characterized by fibrosis and loss of function.
- Causes include chronic hepatitis, alcohol use, and toxins.
- Symptoms: Fatigue, jaundice, ascites, signs of liver failure.
- Diagnosis: Liver biopsy, blood tests, endoscopy for varices.
Oral Manifestations and Dental Management in Cirrhosis
- Jaundice in the oral cavity, potential for bleeding.
- Avoid hepatotoxic drugs; physician consultation mandatory before invasive procedures.
Liver Cancer (Hepatocellular Carcinoma)
- Malignant liver tumor, frequently arising in patients with chronic HBV/HCV or cirrhosis.
- Symptoms: Abdominal pain, weight loss, ascites, jaundice.
- Diagnosis: Liver biopsy, elevated alpha-fetoprotein, imaging studies.
- Management: Surgical resection, chemotherapy, palliative care for pain.
Jaundice
- Characterized by yellow discoloration of skin/sclera due to bilirubin deposition.
- Causes categorized as prehepatic, hepatic, or cholestatic.
- Symptoms: Yellow skin, family history in prehepatic cases, liver tenderness in hepatic causes.
Oral Manifestations and Dental Management for Jaundice
- Oral mucosa may appear yellow; bleeding risks must be managed.
- Avoid hepatotoxic drugs; ensure infection control practices for viral hepatitis patients.
Ascites
- Condition involving excess fluid accumulation in the peritoneal cavity, commonly due to liver cirrhosis.
- Symptoms: Abdominal discomfort, increased girth, respiratory issues.
- Dental considerations: No specific oral manifestations, but ensure patient assessment prior to treatment.
