Q

Explain

Takotsubo cardiomyopathy

A

Temporary weakening of the heart’s muscle, mimicing a heart attack, usually triggered by an emotional or physical stress

Also known as stress cardiomyopathy or broken heart syndrome

Q

Explain

Pneumothorax

A

“Collapsed lung” occurs when air leaks into the space between your lung and chest wall

This air pushes on the outside of your lung and makes it collapse

Q

Explain

Intracardiac shunt

A

An abnormal opening / connection within the heart that allows blood flow between chambers / vessels that bypasses the normal circulation

This can lead to mixing of oxygenated and deoxygenated blood, potentially causing various health problems

Q

Explain

Diffusive alveolar hemmorage (DAH)

A

A serious condition where there is bleeding into the air sacs (alveoli) of the lung, this is life treathening

DAH is not a disease itself, but a manifestation of various conditions

It results from a damaged alveolar-capillary membrane, which separates the air and the blood in the lungs

Q

Explain

Methemoglobinemia

A

A condition where there’s an elevated level of methemoglobin in the blood (a form of hemoglobin that can not bind to oxygen)

This leads to a reduction in the body’s oxygen-carrying capacity, which can lead to a range of symptoms depending on the severity and underlying cause

Q

Explain

Pulmonary hypertension

A

High blood pressure in the blood vessels that supply the lungs (pulmonary arteries) - A serious condition that can damage the right side of the heart

The walls of the pulmonary arteries become thick and stiff and can not expand as well to allow blood trough

Q

Explain

Enzyme

A

Proteins that help speed up metabolism or the chemical reactions in our bodies without being consumed

  • Enzymes are crucial for many bodily functions incl; digestion, blood clotting & growth
  • They work by binding to substrate molecules at an active sight, facilitating a specific chemical reaction

Digestive enzymes like; amylase, lipase & protese help break down food, while lactase & sucrase break down specific sugars

Most enzynmes are proteins, made of linked Amino Acids

Enzymes function best under specific conditions eg. temperature, pH and usually each enzyme typically catalyzes to only one type of reaction, or a small group of similar actions

21
Q

Explain

Amino Acids (AA)

A

Organic compounds that are the building blocks of protein
* AA are linked together to form polypeptide chains, wich fold into specific 3-dimensional structures to create protein

AA contain both an Amino group (-NH2) & a Carboxyl group (-COOH), along with a unique organic side chain (R-group) that distinguishes each AA

22
Q

Define

Creatine

A

Compound that comes from 3 Amino Acids (AA)
* Mostly found in muscles and brain
* Supplies energy to your muscles
* Creatine can be found in milk, steak & some fish

23
Q

Explain

Hemoptysis

A

Coughing blood from lungs

24
Q

Explain

Decubitus position

25
What is the use of **antifibrinolytic** drugs?
To reduce or prevent excessive bleeding by inhibiting *fibrinolysis*, the natural process of breaking down blood clots
26
# Explain Vasopastic angina
Chest pain (angina) caused by a temporary spasm of the coronary arteries (blood vessels that supply the heart muscle) | Typically occurs at rest
27
# Explain Esophageal perforation
**A hole or tear in the esophagus**, this allows fluids and food to enter the chest cavity, potentially causing *mediastinitis* (infl.of the chest cavity) ## Footnote Can be caused by a medical procedure, foreign object, trauma or severe vomiting
28
# Explain Artherosclerosis
**Buildup (plaque) of fats, cholesterol & other substances in and on the artery walls** * This plaque can cause the arteries to narrow, blocking blood flow * Can also burst, leading to a blood clot
29
# Explain Familial hypercholesterolemia
**Genetic disorder that causes very high levels of low density lipoprotein (LDL) cholesterol, aka "bad cholesterol" in the blood** * Can lead to a higher risk of coronary artery disease (CAD) and heart attacks * Typically caused by a mutation in a gene that helps the body remove LDL cholesterol from the blood
30
# Explain Metastasis
Cancers are malignant neoplasms which are not encapsulated. Their cells tend to divide, grow & travel to adjacent and distant sites where they form secondary cancers -- Metastasis
31
Where do the most common neoplasms (tumors) originate from?
From the Epithelial Cells ## Footnote Most cancers originate in the epithelium of the skin, breast, colon, lung & prosate
32
How do Benign Neoplasms usually behave?
They occur locally, are encapsulated & slow growing
33
How do cancers often spread?
In direct contact with adjacent tissues or via the blood / lymphatics | Many cancers grow rapidly and consume most of the body's nutrients
34
# Fill the sentence Epithelial cancers are termed as .... ?
Carcinomas | These tumors may be benign or malignant ## Footnote Before becoming cancerous tumors usually undergo a change as dysplasia or metaplasia
35
# Define Dysplasia
Abnormal development
36
# Define Metaplasia
Abnormal development
37
# Define Osteoporosis | (Porous bone)
Most common bone disease resulting from an imbalance between bone resorption & bone formation - this places bones at great risk for fracture
38
How does avascular necrosis occur?
Loss of blood supply to the epiphysis / other portion of bone, often occuring at a fracture site
39
# Define Osteoarthritis
The progressive loss of articular cartilage & failure of repair ## Footnote Can affect any synovial joint but is most common in the feet, hips, spine & hands. Once the articular cartilage is degraded & lost, the exposed bone (subchondral-beneath the cartilage) rub against eachother causing significant pain
40
# Define Bursitis
Secondary inflammation of the bursa | Painful & can lead to increased synovial fluid in the bursa ## Footnote As muslces pass over a joint, their tendons are cushioned by a fibrous sack - **bursa**
41
# Define Muscle atropy
"Wasting" of muscle tissue that may result from immobilization or a disorder of the muscle itself (muscle tears, rupture of tendon, decrease in blood supply, myocardial infarction or loss of innervation)
42
What are cortical regions ?
Distinct areas of the brain's cerebral cortex ## Footnote Specialized for different functions such as processing sensory information (visual, auditory, somatosensory), controlling voluntary movement, and performing higher-level cognitive tasks (association areas)
43
What can cause damage to the cortical regions ?
Vascular lesions such as infarcts & hemmorage
44
What is **ischemia** ?
Lack of sufficient blood flow
45
What is **anoxia** ?
Lack of oxygen
46
What is **expressive aphasia** ?
Impaired motor speech function
47
What is **receptive aphasia** ?
Impaired understanding of spoken language
48
What is **global aphasia** ?
All speech & communication are impaired
