When treat a person under 80 with stage 1 HPTN
Diabetic (ACEi)
Renal disease
QRISK2 >10%
Established coronary vascular disease or end organ damage
Mild falre of UC
Fewer than four stools daily with or wothout blood
No systemic disturbance

4-6 stools a day w minimal systemic disturbance
Severe flare of UC
> 6 stools a day containing blood
Evidence of systemic disturbance eg
Fever
Tachycardia
Abdo tenderness, distension, reduced bowel sounds

NIV key indications
COPD w reps acidosis pH 7.35-7.35
T2 resp failure secondary to chest wall deformity, Neuromuscular disease or obstructive sleep apnoea
Cardiogenic pulmonary oedema unresponsive to CPAP
Weaning from tracheal intubation
What glaucomas are myopia vs hypermetropia ass with
Hypermetropia - acute angle closure glaucoma
Myopia 0 primary open angle glaucoma
Risk factors for primary open angle glaucoma
increasing age
affects < 1’5 in individuals under 55 years of age
but up to 10% over the age of 80 years
genetics
first degree relatives of an open-angle glaucoma patient have a 16% chance of developing the disease
Afro Caribbean ethnicity
myopia
hypertension
diabetes mellitus
corticosteroids
Fundoscopy signs POAG
- Optic disc cupping - cup-to-disc ratio >0.7 (normal = 0.4-0.7), occurs as loss of disc substance makes optic cup widen and deepen
- Optic disc pallor - indicating optic atrophy
- Bayonetting of vessels - vessels have breaks as they disappear into the deep cup and re-appear at the base
- Additional features - Cup notching (usually inferior where vessels enter disc), Disc haemorrhages
Investigations for POAG
automated perimetry to assess visual field
slit lamp examination with pupil dilatation to assess optic nerve and fundus for a baseline
applanation tonometry to measure IOP
central corneal thickness measurement
gonioscopy to assess peripheral anterior chamber configuration and depth
Assess risk of future visual impairment, using risk factors such as IOP, central corneal thickness (CCT), family history, life expectancy
What are glaucomas
optic neuropathies ass w raised intraocular pressure
open - iris clear of trabecular meshwork
Closed - iris blocking meshwork
First line investigation sus cauda equina
Urgent MRI spine (within 6 hours)
What does concurrent leg pain, new neurological deficit and back pain suggestive of
Spinal nerve impingement in spine
What symptoms are suggestive of cauda equina
Urinary symptoms with saddle anaesthesia and abnormal rectal examination
Complications of cauda equina
New incontinence and paralysis of lower limbs, irreversible within hours
Causes of cauda equina
the most common cause is a central disc prolapse
this typically occurs at L4/5 or L5/S1
other causes include:
tumours: primary or metastatic
infection: abscess, discitis
trauma
haematoma
What does erythema migrans suggest
Bulls eye shaped rash concentric red rings - lyme disease
Features of erythema migrans
Bulls eye shaped rash concentric red rings
painless
1-4 weeks after initial bite
Complications of lyme disease
MSK, neuro, cardio
Arthritis, encephalitis, nerve palsies, arrhythmias
What to prescribe for cauda equina syndrome
Doxycycline if erythema migrans present and treatment initiated based on presence alone
Treatment if disseminated lyme disease
IV ceftriaxone
