ENT + fundoscopy + endocine Flashcards
Hypertensive retinopathy causes changes in the blood vessels supplying the eye - what are these?
- Silver wiring or copper wiring (arterioles wall become thickened and sclerosed causing increased reflection of the light)
- Arteriovenous nipping is where the arterioles cause compression of the veins where they cross (due to sclerosis and hardening of the arterioles)
- Cotton wool spots are caused by ischaemia and infarction in the retina causing damage to nerve fibres.
- Hard exudates are caused by damaged vessels leaking lipids into the retina.
- Retinal haemorrhages are caused by damaged vessels rupturing and releasing blood into the retina.
- Papilloedema is caused by ischaemia to the optic nerve resulting in optic nerve swelling (oedema) and blurring of the disc margins.
Keith-Wagener Classification of hypertensive retinopathy
Stage 1: Mild narrowing of the arterioles
Stage 2: Focal constriction of blood vessels and AV nicking
Stage 3: Cotton-wool patches, exudates and haemorrhages
Stage 4: Papilloedema

Whats this?

Eye showing treatment with laser photocoagulation
Diagnosis

Diabetic retinopathy (mild) - haemorrhages and microaneurysms can be seen
?

Diabetic retinopathy - hard exudates + evidence of macula involvement
* Compared to hypertensive retinopathy DR has more exudates, extensive oedema and multiple haemorrhages
* Hypertensive R has moire cotton wool spots and flame shaped haemorrhages
?

Papillodema - disc is swollen + disc margin has dissapeared + veins are congested
?

Hypertensive retinopathy

Hypertensive retinopathy
landmarks of inside the ear

- pars flaccida
- pars tensa
- handle of the malleous
- Umbo
What is this and its symptoms

Cholesteatoma
- hearing loss
- Malodorous discharge
- Possibly dizziness
** not an emergency but needs to referrred
?
Septal haematoma - usually bilateral + patient will usually complain of a blocked nose
How to manage a nose bleed
- pinch the nasal alar (most bleeding comes form Little’s Area)
- Lean FORWARD (protect the airway)
- Once holding the nose don’t let go (allow a clot to form)
- Cool the head by Sucking on an ice cube (encourage vasoconstriction)
Managment of tonsillitis?
Usually viral but do centor criteria
- if 0-2: rest and fluid
- if 3-4 then give antibiotics: Phenoxymethylpenicillin 500mg for 5-10 days (if allergic clarithromycin/erythromycin)
** avoid amoxicillin -risk of glandular fever
Management of leucoplakia

- Referral to ENT
- Oral surgery for assessment
?

Mouth cancer
- When taking the history what are the important aetiological factors to consider?
Smoking
Alcohol consumption
Betel nut
Family history of mouth cancer
Immunosuppression
HPV infection
Management of hypothyroidism
Levothyroxine 50 mcg then repeat blood in 6 months
Management of iron deficienncy anaemia
Prescribe iron tablets: ferrous fumarate/ sulphate
What can
B12 deficiency cause? and what investigation would you do
- anaemia due to impaired RBC production
- pins and needles
- visual disturbance
- memory loss
**FBC, vitamin b 12: would show raised MCV, HB and B12
Patient presents assymptomatic with Hba1c 44mmol/L? what is he and next steps
Pre-diabetic
- give lifestyle advise
- recheck hba1c in a year
if pre-diabetic patient presents a year after still assymptomatic with hba1c 57 - what to do?
Repeat Hba1c and offer lifestyle advise
**pt comes back and still high -
- give metformin 500 mg once daily
- Refer for structured education/ diabetic awareness programme
- Assess for complications of diabetes.
- Inform DVLA abotu condition
If continues to rise (>58 mmol/l - aim 53) - 2nd line
- consider dual therapy so add: DPP4i (sitagliptin)/pioglitazone or Sulfylurea
- (gliclazide)
if unsuccessful: triple therapy with metformin
- Or metformin + insulin
Treatment targets for diabetic patients
SIGN Guidelines 2017 and NICE Guideline 2015 recommend the following HbA1c treatment targets:
- 48 mmol/mol for new type 2 diabetics
- 53 mmol/mol for diabetics that have moved beyond metformin alone
Diabetic meds
What does diabetic year check up involve
- foot check
- eye check (not in GP)
- BMI
- BP
- Bloods for HbA1c, Renal function, Lipids
- Urinary ACR
if patient blood test showed:
eGFR 50ml/min + •ACR 2.9mg/mmol?
what does this mean
CKD stage 3
other evidence of chronic kidney damage may be one of the following:
- persistent microalbuminuria
- persistent proteinuria
- persistent haematuria (after exclusion of other causes, e.g. urological disease)
- structural abnormalities of the kidneys demonstrated on ultrasound scanning or other radiological tests, e.g. polycystic kidney disease
