Study Notes
Pancreatitis
- Chronic pancreatitis is characterized by persistent symptoms, fibrogenic factors, and tends to predominate over weeks and months.
- There is overlap between the cytokines released during chronic and acute pancreatitis.
Gastroesophageal Reflux Disease (GERD)
- GERD is characterized by inflammation of the esophageal mucosa and impaired closure of the lower esophageal sphincter (LES).
- Transient LES relaxation is believed to be a primary cause of GERD. This relaxation is often mediated by vagal pathways and can be triggered by gastric distention.
- Several factors contribute to GERD, including medications, fatty foods, caffeine, alcohol (ETOH), smoking, sleep position, obesity, and low stomach acid.
- Symptoms associated with GERD include heartburn, regurgitation, chest pain, and dysphagia.
- The severity of GERD manifestations depends on the frequency, duration, volume, and acidity of the refluxed materials.
- Complications of GERD can include esophageal strictures, cough, asthma, laryngitis, and Barretts Esophagus.
- Diagnosis of GERD typically involves clinical assessment of the patient's symptoms.
Peptic Ulcer Disease (PUD)
- PUD involves chronic mucosal ulceration affecting the duodenum or stomach.
- Hyomotility (stasis of bile) allows for stone growth.
Appendicitis
- Appendicitis is initiated by progressive increases in intraluminal pressure that compromise venous outflow, leading to inflammation of the vermiform appendix.
- Luminal obstruction, often caused by a fecalith, gallstone, tumor, or parasitic worms, plays a role in the development of appendicitis.
- Classic symptoms include periumbilical pain, right lower quadrant (RLQ) pain, nausea, vomiting, fever, diarrhea, RLQ tenderness, rebound tenderness, and systemic signs of inflammation.
- "McBurney's point" is a specific area of deep tenderness located two-thirds of the distance from the umbilicus to the right anterior superior iliac spine. While this is a classic finding, it can be located anywhere.
- In the case of a ruptured appendix, sepsis and shock can occur as serious complications.
- Appendicitis is diagnosed primarily based on clinical symptoms and confirmed by imaging studies such as CT scans.
Liver Disease
- Hepatic disease can range from acute to chronic to failure stages, with each stage presenting its own set of clinical manifestations and complications.
Acute Liver Disease
- Acute liver disease is associated with inflammation of the liver.
Chronic Liver Disease
- Chronic liver disease is a long-term condition associated with persistent inflammation of the liver.
Liver Failure
- Liver failure is a serious condition that occurs when the liver is unable to function properly.
- Liver failure can lead to various life-threatening complications, including brain swelling, bleeding, infections, kidney failure, esophageal varices, hepatic encephalopathy, low blood sugar, abdominal swelling, respiratory failure, peritonitis, hepatopulmonary syndrome, and hepatorenal syndrome.
Hepatitis
- Hepatitis is an inflammation of the liver that can be caused by various viruses, such as HAV, HBV, HCV, HDV, and HEV.
- These viruses are transmitted through different routes, primarily through the fecal-oral route, contact with infected blood, or contaminated water.
Hepatitis A (HAV)
- Hepatitis A is spread through the fecal-oral route, typically by consuming contaminated food or water.
Hepatitis B (HBV)
- Hepatitis B is caused by a DNA virus and is transmitted through contact with infected blood, bodily fluids, or during childbirth.
- Chronic HBV infection can lead to cirrhosis and liver cancer.
Hepatitis C (HCV)
- Hepatitis C is caused by a single-stranded RNA virus transmitted through contact with infected blood.
- Most people with HCV are asymptomatic, but those who develop symptoms may experience fatigue, nausea, abdominal pain, loss of appetite, and jaundice.
Hepatitis D (HDV)
- Hepatitis D is a defective virus that requires the presence of Hepatitis B virus to replicate.
- HDV infection can cause severe forms of liver disease, including liver failure.
Hepatitis E (HEV)
- Hepatitis E is transmitted through the fecal-oral route, often through contaminated water.
- While most people experience mild symptoms, some patients may experience liver failure.
Chronic Hepatitis
- Chronic hepatitis is a long-term condition of persistent liver inflammation.
Autoimmune Hepatitis (AIH)
- Autoimmune hepatitis is a chronic disease caused by the body's immune system attacking its own liver tissues.
- AIH can lead to liver damage and potentially liver failure.
Parathyroid Glands and Parathyroid Hormone (PTH)
- The parathyroid glands are small glands located near the thyroid gland.
- The main function of the parathyroid glands is to produce parathyroid hormone (PTH).
- PTH plays a critical role in maintaining calcium homeostasis by regulating the levels of calcium, phosphorus, and magnesium in the body.
- Proper functioning of the nervous and muscular systems as well as bone health is dependent on PTH.
Actions of Parathyroid Hormone (PTH)
- PTH has diverse actions on the body, encompassing:
- Bone: stimulating osteoclast activity, which releases calcium and phosphate from bone into the bloodstream, increasing serum calcium levels.
- Kidneys: increasing calcium reabsorption and phosphate excretion, helping to retain calcium and excrete phosphate in the urine.
- Intestines: indirectly increasing calcium absorption from the gastrointestinal tract through the action of calcitriol.
- Feedback Regulation: regulating secretion of PTH through a negative feedback loop, ensuring calcium balance. Low blood calcium simulates PTH release, while high calcium inhibits it.
Clinical Significance
- Hypoparathyroidism: Low PTH levels can cause hypocalcemia, leading to muscle spasms, tingling, and even life-threatening tetany.
- Hyperparathyroidism: Excess PTH results in hypercalcemia, which can cause osteoporosis, kidney stones, and neuromuscular issues.
Fibrosis
- Fibrosis is a condition that develops with increasing liver damage
- Fibrosis manifests initially as portal and periportal fibrosis
Parathyroid Glands
- Composed of two cell types: chief cells and oxyphil cells
Type 1 Diabetes
- An autoimmune disorder in which the body attacks and destroys insulin-producing beta cells in the pancreas
- The destruction is gradual and often influenced by genetics and environmental triggers such as viral infections
- Key stages in Type 1 Diabetes Development:
- Genetic Susceptibility: Certain HLA genotypes make individuals more likely to develop autoimmune reactions that target beta cells
- Autoimmune Activation: Environmental triggers can activate the immune response leading to production of autoantibodies such as insulin and glutamic acid decarboxylase
- Progressive Beta Cell Destruction: Activated CD8+ T cells and cytokines further destroy beta cells, leading to a reduced insulin production
Growth Hormone
- Stimulates the liver to produce IGF-1 which is a hormone that promotes the growth of soft tissues and bone
- Can cause persistent hyperglycemia and increased insulin production, a diabetogenic hormone
Acromegaly
- Occurs in adults
- Physical Changes:
- Enlarged hands and feet (ring or shoe size increases)
- Frontal Sinus Enlargement: causes prominent brow
- Mandible Growth: leads to progressive underbite
- Coarse Facial Features: squaring of jaw, skin tags
Pituitary Gigantism
- Occurs in children
- Occurs before epiphyses close, leading to excessive height and growth velocity
- Untreated Outcome: Height may exceed 8 feet, Increased risk of cardiomegaly and heart failure
