    • Posticteric Phase: Increased energy levels and resolution of jaundice.

    Treatment of Hepatitis

    • Antiviral medications are prescribed for Hepatitis A, B, and C.
    • Interventions include rest, proper nutrition, and avoidance of hepatotoxic medications.

    Essential Concepts

    • Cholecystitis is frequently linked to cholelithiasis (gallstones) and presents specific risk factors and symptoms.
    • Hepatitis can be caused by various factors and exhibits three distinct phases, each with unique signs and symptoms.
    • Understanding different hepatitis types helps frame their management and preventive measures.

    Cholecystitis

    • Cholecystitis is the inflammation of the gallbladder, often associated with obstruction caused by gallstones.
    • Pathophysiology includes increased pressure leading to reduced blood flow and resultant ischemia, with bile retention acting as a chemical irritant.
    • Risk factors include age over 60, family history, obesity, rapid weight loss, and biliary stasis.
    • Symptoms include acute pain in the right upper quadrant, especially after fatty meals, nausea/vomiting, fever, and jaundice.
    • Diagnosis commonly performed via abdominal ultrasound.
    • Treatment includes oral bile acids, with a recommended low-fat diet to manage symptoms.
    • Surgical treatment typically involves cholecystectomy (removal of the gallbladder).

    Hepatitis

    • Hepatitis is the inflammation of the liver, primarily caused by viral infections, alcohol consumption, and exposure to toxins.
    • Known hepatotoxins include specific medications: amoxicillin-clavulanate, flucloxacillin, erythromycin, diclofenac, and acetaminophen among others.
    • The pathophysiology involves inflammation which can impair bilirubin elimination.
    • Bilirubin is derived from hemoglobin breakdown in the bone marrow, fat metabolism, and the Krebs cycle.

    Hepatitis Types

    • Hepatitis A:

      • Route: Fecal-oral transmission.
      • Onset: Abrupt symptoms.
      • Prevention: Vaccine available.

    • Hepatitis B:

      • Route: Blood and body fluids.
      • Onset: Slow progression.
      • Complications: Potential for chronic infection and liver cancer.
      • Prevention: Vaccine and standard precautions.

    • Hepatitis C:

      • Route: Blood and body fluids.
      • Onset: Slow onset.
      • Complications: Chronic infection and increased cancer risk.
      • Prevention: Standard precautions.

    Symptoms of Hepatitis

    • Preicteric Phase: Flu-like symptoms, gastrointestinal upset, joint pain, and right upper quadrant pain.
    • Icteric Phase: Characterized by jaundice, pruritus (itching), clay-colored stools, and dark urine.
    • Posticteric Phase: Increased energy levels and resolution of jaundice.

    Treatment of Hepatitis

    • Antiviral medications are prescribed for Hepatitis A, B, and C.
    • Interventions include rest, proper nutrition, and avoidance of hepatotoxic medications.

    Ulcerative Colitis Symptoms and Complications

    • Diarrhea is a prominent symptom, often frequent and urgent.
    • Blood, pus, and mucus may be present in stool.
    • Patients experience fecal urgency leading to frequent, desperate urges to defecate.
    • Abdominal pain is common, particularly in the lower left quadrant (LLQ) during defecation.
    • Anemia and decreased serum protein levels may indicate malnutrition.

    Ulcerative Colitis Complications

    • Perforation of the colon can be a life-threatening complication.
    • Hemorrhage can occur, leading to significant blood loss.
    • Dehydration results from severe diarrhea and fluid loss.
    • Increased risk of colon cancer is associated with long-standing ulcerative colitis.

    Crohn’s Disease Pathophysiology

    • Considered an autoimmune disorder with chronic and relapsing characteristics.
    • Affects the entire gastrointestinal tract, not limited to specific areas.
    • "Skip lesions" are characteristic, where segments of healthy tissue are interspersed with inflamed areas.

    Effects of Crohn’s Disease

    • Lesions can lead to the formation of fistulas or fissures, complicating the condition.
    • Tissue damage results in scarring and narrowing of the intestines.
    • Intestinal obstruction may occur due to strictures.
    • Thickening of the intestinal wall can contribute to malabsorption issues.

    Crohn’s Disease Symptoms

    • Persistent diarrhea is a key symptom, often accompanied by urgency.
    • Abdominal pain is prevalent, particularly in the right lower quadrant (RLQ).
    • Patients are likely to experience anemia due to nutritional deficits.

    Crohn’s Disease Complications

    • Obstruction of the intestines can require surgical intervention.
    • Fistulas or abscesses may form, creating further complications.
    • Malabsorption and malnutrition are common due to damaged intestinal functioning.
    • Increased risk of colon cancer is present with Crohn’s disease.

    Diagnosis of Inflammatory Bowel Disease (IBD)

    • Stool cultures are conducted to identify pathogens or causes of diarrhea.
    • Complete blood count (CBC) is performed to assess for anemia and infection.
    • Colonoscopy is essential for direct visualization and diagnosis of IBD.

    Medications for IBD Treatment

    • Anti-inflammatory agents are commonly prescribed to reduce inflammation.
    • Corticosteroids may be used for their potent anti-inflammatory effects during flare-ups.

    Dietary Management for IBD

    • Nutritional supplements are often necessary to address deficiencies.
    • Increased fiber intake may aid in digestion, but should be managed carefully.
    • Limiting dairy products and avoiding spicy foods can help reduce irritation.

    Dietary Management During Exacerbations

    • Bowel rest is recommended to allow the gut to heal.
    • NPO (nothing by mouth) status may be indicated during severe exacerbations to prevent further irritation.
