Thrombotic -Cholesterol plaque stick to inner wall allowing build-up.
intracranial- Pia matter
Subarachnoid -The main symptom is a sudden, severe headache. layer between brain and layer of protection

Question 13

Patho of emphysema

Answer 13

Emphysema is a pathologic diagnosis defined by permanent destruction of airspaces distal to the terminal bronchioles. This leads to a dramatic decline in the alveolar surface area available for gas exchange. Furthermore, loss of alveoli leads to airflow limitation by 2 mechanisms. First, loss of the alveolar walls results in a decrease in elastic recoil, which leads to airflow limitation. Second, the loss of the alveolar supporting structure leads to airway narrowing, which further limits airflow. Caused by smoking and air pollution

Question 14

Path of Chronic Bronchitis

Answer 14

Inflammation of the central airways is a prominent feature in subjects with chronic bronchitis. The pathology of chronic bronchitis includes an inflammatory cell infiltrate in the airway wall and a neutrophil influx into the airway lumen. The molecular events that produce the inflammation-causing mucus hypersecretion The inflammatory cell recruitment to the airways likely involve chemotactic agents derived not only from tissue fluid. synthesize neutrophils and lymphocytes.

Question 15

Patho of pneumonia

Answer 15

pneumonia is an umbrella term for a group of syndromes caused by a variety of organisms. Bacteria, fungal, and viral when body function detects it releases systemic action to defeat the orgasms such as rise in temp, mucus production, and sweating.

Question 16

Patho of Croup

Answer 16

Croup causes swelling of the larynx, trachea, and large bronchi due to the infiltration of white blood cells. Swelling results in partial airway obstruction which, when significant, results in dramatically increased work of breathing, and the characteristic turbulent, noisy airflow known as stridor due to the infiltration of white blood cells. The parainfluenza virus typically causes croup, but a bacterial infection can also cause it.

Question 17

Patho of Bronchilitis

Answer 17

Bronchiolitis is inflammation of the bronchioles usually caused by an acute viral illness. It is the most common lower respiratory tract infection in children younger than 2 years of age. Bronchiolitis occurs as a result of the inflammation of the lining of the epithelial cells of the small airways in the lungs causing mucus production, inflammation, and cellular necrosis of those cells. It is the inflammation of these cells that can obstruct the airway and ultimately result in wheezing.

Question 18

Patho of Pertussis

Answer 18

Whooping cough, also known as pertussis or the 100-day cough, is a highly contagious bacterial disease. The initial symptoms are usually similar to those of the common cold with a runny nose, fever, and mild cough, but these are followed by weeks of severe coughing fits.compromises the small airways (especially those of infants) and predisposes the affected individual to atelectasis, cough, cyanosis, and pneumonia.
kills cilicac cells releases toxins and reduce inflammatory response in the bronchioles. causing a prolonged response.

Question 19

Patho of ACS

Answer 19

decreased blood flow to part of heart musculature which is usually secondary to plaque rupture and formation of thrombus. Sometimes ACS can be secondary to vasospasm with or without underlying atherosclerosis. The result is decreased blood flow to a part of heart musculature resulting first in ischemia and then infarction of that part of the heart.

Question 20

Path of Cardiogenic

Answer 20

Cardiogenic shock is characterized by inadequate tissue perfusion due to cardiac dysfunction, and it is often caused by acute myocardial infarction. ischemia causes myocardial dysfunction Myocardial stunning. Low perfusion pressures with global ischemia lead to multiorgan dysfunction. E.g Hypotension+ tachycardia

• Shoulder tip pain

Question 22

Patho of pancreatitis

Answer 22

obstruction( gall stones, alcohol use ) of pancreatic secretory transport and by an activation of pancreatic enzymes. In biliary acute pancreatitis, outflow obstruction with pancreatic duct hypertension and a toxic effect of bile salts contribute to disruption of pancreatic ductules, with subsequent loss of extracellular compartmentation. Alcohol induces functional alterations of plasma membranes and alters the balance between proteolytic enzymes and protease inhibitors, thus triggering enzyme activation, autodigestion and cell destruction.

Question 23

Patho of upper/lower GI

Answer 23

Oesophageal varices -Develop through portal hypertension and dilates veins causing to rupture causing bleeds. Varices are pooling of blood . The veins drain blood, although if bleeding endo tube can see if bleeding occure

  • When progresses it reaches to kidneys and colonise causing kidney failure or sepsis

Question 25

Patho of Diabetes

Answer 25

Diabetes mellitus is a chronic disease caused by the imbalance of insulin supply and demand. It leads to hyperglycemia and abnormal carbohydrate, fat, and protein metabolism. Alpha glucose and bets are insulin • Type I diabetes mellitus is caused by autoimmune destruction of beta cells in the pancreas, which leads to an absolute insulin deficiency (birth) • Born with a genetic condition which is caused by the environment • T cells attack beta cells • Symptoms develop through brain, muscles, and liver • Insulin is present so liver releases glucose in response acting like its starving to take up in adipose fatty tissue that digests it for further energy causing lethargy and fatigue • Glucose overwhelm kidneys infiltration and draws more water through urine * Type II diabetes mellitus has a gradual onset of hyperglycemia and is the result of the development of resistance to the action of insulin and insufficient insulin secretion(age) * Dysfunction of beta cells responding to high glucose * Insulin resistance * Genetic hx can be caused but also hypertension , overweight and age * Obesity over time the receptors become desynthesises over time as it becomes used at high amounts .

Question 26

Patho of gastroenteritis

Answer 26

he 2 primary mechanisms responsible for acute gastroenteritis are (1) damage to the villous brush border of the intestine, causing malabsorption of intestinal contents and leading to an osmotic diarrhea, and (2) the release of toxins that bind to specific enterocyte receptors and cause the release of chloride ions into the intestinal lumen, leading to secretory diarrhea. Norovirus - Rotavirus - Astrovirus - Enteric Adenovirus

Question 27

Path of Pulmonary embolism

Answer 27

``` Pulmonary embolism (PE) is a blockage of an artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream (embolism).Most times, a pulmonary embolism is caused by blood clots that travel from the legs, or rarely, other parts of the body (deep vein thrombosis or DVT). Symptoms include shortness of breath ,pleuritic chest pain and cough up of blood sputum. Worsening chest pain when lying supine .Obstruction of the pulmonary arteries creates dead space ventilation as alveolar ventilation exceeds pulmonary capillary blood flow.This contributes to ventilation-perfusion mismatch, with vascular occlusion of the arteries increasing pulmonary vascular resistance ```

Question 28

MND /ALS

Answer 28

motor neuron disease (MND) is a progressive, neurodegenerative disorder that mainly attacks the human motor system, leading to significant disability and ultimately death, usually within 3 years.Genetic .These factors include early management of respiratory dysfunction with non-invasive ventilation, Amyotrophic lateral sclerosis (ALS) represents 70% of cases.3,6 ALS classically begins in the limb and exhibits a combination of upper and lower motor neuron signs.3,6 In about 20% of patients, the weakness starts in the bulbar region. Upper motor -stiffness ,slow ,spasm, hyperflexia Lower motor -fluctuations, weakness and spasm

Question 29

MS

Answer 29

• De-myelinating disease • Multiple sclerosis is a disease in which the immune system eats away at the protective covering of nerves. • In MS, resulting nerve damage disrupts communication between the brain and the body. • Reduce velocity of communication • Immune system sneaks inti nerves and sees myelin as foreign • This is autoimmune disease degraders white matter ( myelin ) causing damaged or lesions to the brain . • Causes plaques and lesions in the brain having damaged immune system causing neuroinflammation . • T cells mistakes myelin and attacks its attached proteins and promote degradation ,recuit immune cells( b cell)and macrophages • Multiple sclerosis is multiple plaques • Physiotherapy and medication that suppress the immune system can help with symptoms, and slow disease progression. Multiple sclerosis causes many different symptoms, including vision loss, pain, fatigue and impaired coordination

Question 30

DKA/ HHS

Answer 30

Diabetic ketone acidosis and hypergylcemic and hyperpolar nonkenotic coma occurs when the body starts breaking down fat at a rate that is much too fast. The liver processes the fat into a fuel called ketones, which causes the blood to become acidic elevated levels of counter regulatory hormones: glucagon (16,17), catecholamines (16,18), cortisol (16), and growth hormone (19,20), resulting in increased hepatic glucose production and impaired glucose utilization in peripheral tissues, and 3) dehydration and electrolyte abnormalities, mainly due to osmotic diuresis caused by glycosuria (21) (Figure 3). Diabetic ketoacidosis is also characterized by increased gluconeogenesis,

Question 31

Patho Parkinson's

Answer 31

These include paucity and slowness of movement (akinesia, bradykinesia), muscle stiffness (rigidity), and tremor at rest. In large part, these problems result from the prominent degeneration of dopaminergic neurons in the midbrain, and the consequent deficiency of dopamine in brain areas that receive dopaminergic inputs from those neurons, specifically the post-commissural putamen and other basal ganglia regions.

Question 32

Answer 32

Hematochezia is the passage of fresh blood per anus, usually in or with stools.

Question 33

Melena

Answer 33

Dark tarry stool with or without visible blood.

Question 34

oesphageal varcies

Answer 34

Esophageal varices are enlarged veins in the esophagus. They're often due to obstructed blood flow through the portal vein, which carries blood from the intestine, pancreas and spleen to the liver.

Question 35

volvus

Answer 35

A volvulus is when a loop of intestine twists around itself and the mesentery that supports it, resulting in a bowel obstruction.

Question 36

ascities

Answer 36

Ascites is the abnormal buildup of fluid in the abdomen. Technically, it is more than 25 ml of fluid in the peritoneal cavity. Symptoms may include increased abdominal size, increased weight, abdominal discomfort, and shortness of breath. Complications can include spontaneous bacterial peritonitis.caused by liver scarring, otherwise known as cirrhosis. Scarring increases pressure inside the liver's blood vessels. The increased pressure can force fluid into the abdominal cavity, resulting in ascites.

Question 37

CHF and pulmonary odema

Answer 37

Congestive heart failure (CHF) is an imbalance in pump function in which the heart fails to maintain the circulation of blood adequately. The most severe manifestation of CHF, pulmonary edema, develops when this imbalance causes an increase in lung fluid secondary to leakage from pulmonary capillaries into the interstitium and alveoli of the lung.
