Viral gastroenteritis is thesecond most common illness in the U.S. (Centers for DiseaseControl and Prevention) NIDDKNational institute of diabetes and digestive and kidney diseases (alsoinformation in Spanish)http://www2.niddk.nih.gov/
  11. 11. Hepatitis C Hepatitis C is a viral disease that leads to swelling (inflammation) of the liver.
  12. 12. CausesHepatitis C infection is caused by the hepatitis C virus(HCV).
  13. 13. Signs and SymptomsHepatitis C infection usually produces no signs or symptomsduring its earliest stages. When signs and symptoms do occur,theyre generally mild and flu-like and may include: • Fatigue • Muscle and joint pains • Fever • Tenderness in the area of your liver • Nausea or poor appetite Testing should be done among: • Individuals at high risk for prior to 1992 infection. • Persons with abnormal levels of • Children born to chronically liver enzymes in the blood infected mothers • Testing is recommended when • People who received blood, blood exposure to the virus is products, or transplanted organs suspected.
  14. 14. MortalityIn a study in the journal Annals of Internal Medicine, U.S.Centers for Disease Control researchers analyzed causesof death on more than 21.8 million U.S. death certificatesfiled between 1999 and 2007. Rates of death related tohepatitis C, a viral infection that causes chronic liverdisease, rose at an average rate of .18 deaths per100,000 persons per year. More than 15,000 people diedfrom hepatitis C in 2007. HIV-related death rates declined.21 deaths per 100,000 people per year — 12,734 peopledied from HIV in 2007. Rates of death related to a thirdinfection, hepatitis B, remained more or less constant overthe study period, falling .02 deaths per 100,000 people peryear to just more than 1,800 deaths in 2007.

  16. 16. Wilsons disease is named after SamuelAlexander Kinnier Wilson (1878–1937), theBritish neurologist who first described thecondition in 1912
  17. 17.  Wilson disease is a rare autosomal recessive inherited disorder of copper metabolism. You need a small amount of copper from food to stay healthy. Too much copper is poisonous. This can cause damage to your brain, liver, and eyes.
  18. 18.  the most common one KAYSER-FLEISCHER RINGS Symptons can appear in the ages between 6-38
  19. 19. · Fatty liver· Acute hepatitis· Resembling autoimmune hepatitis· Cirrhosis· Acute liver failure
  20. 20.  Movement disorders (tremor, involuntary movements Dysautonomia Migraine headaches Insomnia Seizures Depresion Psychosis Personality changes Neurotic behaviours
  21. 21.  24 hour urine test for copper Liver Biopsy Kayser Fleischer rings
  22. 22.  Wilson disease is a very treatable condition. With proper therapy, disease progress can be halted and oftentimes symptoms can be improved. Treatment is aimed at removing excess accumulated copper and preventing its accumulation. Treatment for Wilson disease is a lifelong process. Patients may become progressively sicker from day to day, so immediate treatment can be critical. Treatment delays may cause irreversible damage.
