    Study Notes

    Hepatitis

    • Acute hepatitis is a liver infection that can be viral, drug-induced, or autoimmune in origin.
    • There are five types of hepatitis: HAV, HBV, HCV, HDV, and HEV.

    Types of Hepatitis

    • HAV (Hepatitis A): most common type, transmitted via fecal-oral route, poor sanitation, contaminated food, water, milk, and shellfish, or oral-anal sexual practices.
    • HBV (Hepatitis B): more severe, transmitted via blood and blood products, breaks in skin or mucous membranes, or from asymptomatic carriers with HBsAg.
    • HCV (Hepatitis C): transmitted via intravenous drug use, sexual contact, blood or blood products, and from asymptomatic carriers, accounts for 90% of post-transfusion hepatitis.
    • HDV (Hepatitis D): transmitted via same routes as HBV, requires HBV surface antigen to replicate, coexists with HBV.
    • HEV (Hepatitis E): transmitted through food or water contamination, seen in developing countries, not encountered in the US.

    Medical Care

    • Laboratory tests: CBC, liver function studies, Anti-HAV IgM, hepatitis B surface antigen, hepatitis Be antigen, Anti-HBc, Anti-HBAg, urine bilirubin, prothrombin time.
    • Liver biopsy: used to determine type of hepatitis and degree of liver necrosis.
    • Liver scans: used to identify level of parenchymal damage.
    • Treatment: symptomatic, prophylactic therapy, immune globulin (IG) for temporary passive immunity, hepatitis B vaccine for active immunity.

    Pneumothorax

    • Occurs when free air accumulates in the pleural cavity between the visceral and parietal areas, causing lung collapse.
    • Pressure in the pleural space...
