Q

Describe the physiology behind allergic rhinitis.

A

Patient develops IgE antibodies against certain antigens in things like like dust, pollen, cats, dogs, etc.
Every time a person in exposed to the antigen, there is a release of histamine leukotrienes prostaglandins from the nose which causes allergic reactions e.g. sneezing.

Q

When may skin tests be used?

A

Can be used to test against different allergens by putting a small sample on needle, prick the skin and then check reaction.

Give an example of a positive control during skin testing.

A patient presents with a broken nose. He got injured during a rugby game last week and comes to the hospital to see the you.

Q

What van happen if septal haematoma is not treated?

25
What would you test if you suspect cystic fibrosis?
Sweat test to check chlorine
26
If a child came in with nasal polys, which condition would you need to rule out?
Cystic fibrosis
27
Which test may be done is someone has severe allergic rhinitis?
Skin tests RACE blood test ->if severe reactions, best patient knows specifically what they are allergic to so that they can avoid it.
28
If doing a nasal smear and there are predominantly neutrophils in the sample, which condition may this be?
Chronic sinusitis.
29
If doing a nasal smear and there are predominantly eosinophils in the sample, what would this suggest?
Allergy based
30
When would you send a patient with nasal issues for an MRI?
If you suspect any intracranial involvement.
31
What is the treatment for nasal polpys?
Oral and nasal steroids Dietary changes to increase vitamins to increase immuinity ->steroid sprays for nasal use are efficient in some, need to be used everyday
32
There lower bioavailability in modern nasal steroids. What is meant by bioavailability?
Amount of drug systemically delivered to the body compared with how much drug the body actually absorbs.
33
If a patient has surgery to remove nasal polyps, which treatment will they still need to take after?
Nasal steroid spray for rest of their lives to reduce chances of them coming back
34
If medical treatment for nasal polyps doesn't' work, which surgery may be considered?
Endoscopic sinus surgery to remove polyps
35
Describe the symptoms of acute sinusitis.
Nasal blockage Nasal congestion Nasal discharge Facial pain Reduction or loss of smell
36
When would acute sinusitis become chronic sinusitis?
Symptoms <4wks= acute >4wks=chronic
37
Majority of acute sinusitis patients do not require antibiotics. However, would would be some indications that a patient does require antibiotics?
Developing complications e.g. orbital oedema, severe headaches, double vision, pus coming from nose.
38
In patients with acute sinusitis with complications, what would be done?
Hospital admission, IV antibiotics, scan, work out if something else is going on
39
Which two strains of bacteria are the most common cause of bacterial rhinosinustitis?
S.pneumoniae H.influenzae
40
Which symptoms would be present in those with chronic sinusitis?
Presence of at least two of the following for at least 12 consecutive weeks: -Nasal obstruction -Nasal drainage -Facial pain -Hyposmia/ anosmia
41
What is the usual medical treatment for chronic sinusitis?
Topical steroids
42
When may a scan be carried out in patients with chronic sinusitis?
If they are not responding to medical treatment
43
Acute sinusitis can have a complication of orbital swelling. This can mean that there is an abscess behind the eye. What is the treatment for this?
Immediate drainage, if not, could result in vision loss
44
What may be the cause of severe headaches as a complication of acute sinusitis?
Pus collections e.g. at front of head. Will need to be drained.
45
What is a mucocele?
Build up of mucus as sinus does not drain it
46
What is the treatment for a mucocele?
Surgically drain mucous via FESS (functional endoscopic sinus surgery).
47
Those on which medications are more likely to have nosebleeds?
Anticoagulants like warfarin
48
Why is the nose one of the most common sites of bleeding?
Exposed to many irritants
49
What are some of the various categories of causes of epistaxis?
Trauma Inflammatory Neoplastic Infective Congenital Genetic
50
Which types of infection may cause a nosebleed?
Rhinitis Sinusitis Nasopharyngitis
51
What is the initial management of epistaxis?
Hold nose to stop bleeding
52
In those with a nosebleed, which part of a history is particular important?
Medical history- which drugs they're on, if they have any bleeding disorders.
53
If bleeding doesn't stop, which procedure can be done in epistaxis?
Cauterisation
54
If you cannot find the blood vessel causing the nasal bleed, cauterisation cannot be done. What may be done instead?
Nasal packing
55
Name an inherited condition which can affect blood vessels and cause bleeding.
HHT (Hereditary haemorrhagic telangiectasia)
56
What may you see upon examination in those with HHT?
Visible red spots on parts of the body like fingers and lips.
57
What is the treatment for those with HHT?
Laser coagulation Septodermoplasty
58
What is angiofibroma?
Rare benign tumour which forms in the nose
59
Who might get an angiofibroma?
Male teenagers Never see in females, nobody knows why
60
What should be done if you suspect angiofibroma?
Biopsy
61
What is the treatment for angiofibroma?
Preoperative embolism Surgery
62
An elderly man presents with mild epistaxis and hearing loss. Upon examination, you see there is fluid in the ear. What might be happening here? Describe your thought process.
Elderly man- children often get fluid but not elderly. Fluid in ear= Eustachian tube not working properly. Connects nose and ear... Tumour= would explain blockage and bleeding
63
How would you confirm the diagnosis of a nasal tumour?
