What should be done in a patient who is on a DMARD in the event of a severe sore throat or abnormal bruising?
Treatment should be withheld, an urgent FBC taken and any blood test abnormalities discussed with specialist team - Provide symptomatic relief - Consider prescribing an antibiotic, taking into account potential interactions with DMARDs
36
What is diphtheria?
Potentially fatal contagious bacterial infection that mainly affects the nose and throat
37
What bacteria causes diphtheria?
Corynebacterium diphtheria
38
Why is diphtheria potentially fatal?
The organism produces a potent exotoxin which is cardiotoxic and neurotoxic
39

Severe sore throat with a grey-white membrane across the pharynx (pseudomembrane)
40
What is shown?
Diphtheria
41
What is shown?
Diphtheria - Pseudomembrane in the posterior pharynx
42
How is diphtheria managed?
- Antibiotic (penicillin/erythromycin) - Antibiotic and diptheria antitoxin for severe cases
43
How is diphtheria prevented?
Toxoid vaccine - made from a cell-free purified toxin extracted from a strain of C. dipththeriae
44
What is infectious mononucleosis (Glandular fever)?
A disease of young adults caused by the Ebstein-Barr virus
45
How does EBV cause infectious mononucleosis?
EBV is a virus of the Herpes family which establishes a persistent infection in epithelial cells, notably in the pharynx
46
In who does infectious mononucleosis more commonly occur?
- Primary infection in early childhood rarely results in infectious mononeucleosis - Primary infection in those >10 years often causes infectious mononucleosis
47
How does glandular fever present?

49
What is shown?
Glandular fever
50
What is shown?
Glandular fever
51
What are some investigations required in glandular fever?

52
How is glandular fever managed?
Self-limiting illness so symptomatic treatment: - Bed rest - Paracetamol - Avoid sport for 6 weeks to avoid splenic rupture

- Stratified squamous epithelium - Stroma oedematous/fibrous/myxoid
64
How are laryngeal nodes and polyps managed?
- Voice therapy - Some cases require surgery to remove the growths
65

67
How will a laryngeal contact ulcer present?
- Mild pain while speaking or swallowing - Varying degrees of hoarseness
68
How is a laryngeal contact ulcer managed?

Reinke's oedema
80
How is Reinke's oedema managed?
- Management of risk factors e.g. smoking cessation - Voice therapy - If the elimination of risk factors is not sufficient to improve the patient's symptoms, surgery may be required
