Q

what causes oedema?

A
  • develops secondary to increased venous pressure but it can also result from reduced oncotic pressure or it be may idiopathic

17
Q

what are the 3 cardiovascular causes of clubbing?

A
  • lung cancer
  • congenital cyanotic heart disease
  • chronic lung infections that occur in people with bronchiectasis, cystic fibrosis or lung abscesses.
  • interstitial lung disease
18
Q

what are non cardiovascular causes of clubbing?

A
  • coeliac disease
  • cirrhosis of the liver
  • overactive thyroid gland
  • cancer
    infective endocarditis
19
Q

infective endocarditis?

A

an infection on the valve of the heart that causes vegetation to that heart valve.
parts of the valve may break of when blood flows causes chromatic and clotting effects.

20
Q

what are signs of infective endocarditis?

A
  • fever
  • heart murmurs
  • petechiae (rash non blanching)
  • splinter hemorrhages (linear lesions under the nail)
  • osler nodes (tender subcutaneous nodules usually found on the distal pads of digits)
  • janeway lesions (tender maculae on the palm and soles)
  • Roth spots. (retinal haemorrhages with small, clear centres)
21
Q

describe Roth’s spots?

A
  • most commonly seen in acute bacterial endocarditis with a pale white centre.
  • the white centre is fibrin plataet plug
  • can be seen in leukaemia, diabetes
  • need a microscope for eyes to see this.
  • white entered retinal haemorrhages
22
Q

xanthelasma?

A

this Is yellow plaques on upper and lower eyelids.
- a marker for atherosclerosis
- increased levels of serum cholesterol and LDL cholesterol.

23
Q

thoracic outlet syndrome?

A
  • actually happens in the thoracic inlet
  • the brachial plexus, subclavian artery and the subclavian vein are closely related to the upper surface of the first rib and the inferior surface of the clavicle as they enter the upper lim.
  • compression to any of these blood vessels or nerves
24
Q

symptoms of thoracic outlet syndrome?

A
  • pain and paraethesia
  • grip weakening
  • discolouration
  • throbbing near clavicle
  • cold hands
  • Raynaud’s phenomenon (decreased blood flow to fingers)
25
Q

coarctation of the aorta?

A

narrowing of the aorta - heart must pump more forcefully

26
Q

Marfan syndrome?

A

common disorder of connective tissue that effects the eyes, skeleton, lungs, heart and blood vessels and it may be life threatening.
it is genetic

27
Q

what are cardiovascular complications of Marfan’s syndrome?

A
  • dilation of ascending and sometimes descending aorta
  • incompetence of aortic and mitral valves
  • aneurysm
  • dissection of aorta.
28
Q

management of Marfan’s syndrome?

A

regular clinical review
- echo
- additional imaging
- Beta blockers
- surgical referral if the aortic root at sinus of valsalva exceeds 5.5cm or 5% growth per year

29
Q

keto-acidosis?

A
  • when there is a severe lack of insulin in the body
  • sugar is not used for energy, instead fat will be
  • ketones are released
30
Q

kussmaul breathing?

A
  • abnormal breathing
  • rapid, deep breathing
  • related to ketoacidosis
31
Q

portal hypertension

A

can’t get blood into liver due to high blood pressure in this system and it flows back due to the fact that there are no valves = portosystemic shunt.

32
Q

what can cirrhotic liver disease cause?

A

portal hypertension-> oesophageal varices

33
Q

thoracic outlet syndrome?

A

when the vessels that run from the thorax to the upper limb become compressed (brachial plexus and subclavian artery/vein)
- this compression can happen between:
- the scalene muscles
- rib 1 and the clavicle
- coracoid process of the scapula and pec minor.

34
Q

coarctation?

A

birth defect where part of the aorta is narrower than usual

35
Q

what are the reasons why someone is not put in a cast when they break a rib?

A

1- haemothorax (blood collects between chest wall and lungs in pleural cavity)
2- pneumothorax (collapsed lung)
3- splenic injury

36
Q

pericarditis?

A
  • inflammation of the pericardium
  • appears as acute onset of chest pain
37
Q

angina pectoris?

A

chest pain that is due to inadequate supply of O2 to the heart, typically severe and crushing

38
Q

prinzemetal angina (variant)

A
  • caused by coronary artery vasospasm
  • uncommon
39
Q

red man syndrome?

A

hypersensitivity reaction to histamine release
vancomycin
- will cause an erythematous rash on the face, neck and upper torso, burning, itching

40
Q

How to treat patent ductus arteriosus?

A

NSAID’s like ibuprofen will act as prostaglandin inhibitors

41
Q

What happens if the ductus arteriosus doesn’t close?

A

Patent ductus arteriosus
- postnatally the aortic pressure is greater than in the pulmonary trunk
- causing blood flowing from systemic circulation back into pulmonary circulation through ductus arteriosus
- pulmonary hypertension
- too much blood will flow into the lungs causing pulmonary oedema and possibly congestive heart failure (right ventricle needs to work harder)

42
Q

Non closure of the foramen ovale?

A
  • PFO (patent foramen ovale)
  • usually asymptomatic
  • may cause paradoxical emboli (a clot causes goes into systemic circulation)
  • causing oxygenated blood to mix with deoxygenated blood
