falling, can’t feel feet, macrocytic anaemia
B12def
A 55 year old man has had lower back pain and fatigue for 3 months. Investigations: Haemoglobin 110 g/L (130–175) White cell count 5.8 × 109 /L (3.8–10.0) Platelets 120 × 109 /L (150–400) Corrected calcium 2.90 mmol/L (2.2–2.6) Albumin 29 g/L (35–50) Serum electrophoresis: monoclonal Ig kappa peak Bone marrow biopsy: foci of plasma cells, which account for 18% of all haematopoietic cells
classic multiple myeloma
pneumonia with AKI
likely pre renal hypoeperfusion
raised creat and urea
interstitial nephritis
Interstitial nephritis would normally not
appear until 4-7 days of antibiotic exposure and is relatively rare
A 70 year old woman has an ulcer above the left medial malleolus. She has a
history of type 2 diabetes mellitus. She smokes 10 cigarettes per day.
The ulcer is 10 × 5 cm and superficial. She has brown discolouration of both
lower legs. The skin has a thickened, waxy feel. Her BMI is 34
classic venous ulcer
. A 67 year old man has 3 weeks of progressive ankle oedema. He has a
history of hypertension, treated with amlodipine. He is a lifelong heavy smoker
and drinks 12 units of alcohol per week.
His BP is 125/85 mmHg and oxygen saturation 98% breathing air. His JVP is
4 cm above the sternal angle. He has marked bilateral pitting ankle oedema.
He has dull percussion note at both bases with reduced breath sounds.
Investigations:
Creatinine 85 µmol/L (60–120)
Fasting glucose 5.7 mmol/L (3.0–6.0)
Total cholesterol 9 mmol/L (<5.0)
Albumin 15 g/L (35–50)
Urinary protein:creatinine ratio 568 mg/mmol (<30)
Urine microscopy no cells, no casts
The combination of hypoalbuminaemia, proteinuria, oedema, hypercholesterolaemia
etc. is characteristic of nephrotic syndrome. The most likely causes in the age group
(without diabetes) would be membranous nephropathy, minimal change or FSGS.
Myeloma would also need to be considered. A renal biopsy would be required to
confirm the diagnosis
back pain red flags (some of them lol)
wakes from sleep
going on for many weeks
older age
need plain x rays
postinfectious GN
Postinfectious
GN would follow a clear-cut infection, particularly streptococcal sore throat
classic IgA vasculitis /HSP
Classic presentation of HSP with a purpuric (vasculitic) rash and an active urinary
sediment. Abdominal and joint pain may also occur. Renal function is usually normal
buttock rash
SLE history and picture
SLE
would normally have a longer history, does not typically give a vasculitis rash and
would be associated with other features of SLE e.g. alopecia, arthralgia, skin rash,
cytopenias, mouth ulcers.
oxybutinin side effect
Oxybutynin is an anticholinergic and a frequent cause of constipation
A 65 year old man reports sudden onset of visual disturbance with flashing
lights, floaters and loss of vision in the upper outer quadrant of his right eye.
He has a history of hypertension.
retinal detachement
increasing number of floaters classic then flashing lights as tears off
most likely post op complication if fever and reduced sats
The development of a fever in the early postoperative period, in combination with
reduced oxygen saturation, is most likely to be due to the development of bibasal
atelectasis, especially in a patient who has undergone an abdominal procedure and
is experiencing pain.
A 69 year old man has 6 months of back pain extending into his buttocks and
back of his thighs. The pain is worse on standing and on walking, and is
relieved when he sits down and leans forward. He has diet-controlled type 2
diabetes mellitus. He is an ex-smoker with a 40 pack-year history.
His BP is 178/95 mmHg. He has weakness of hip flexion bilaterally. His
peripheral pulses are palpable
neurogenic claudication

small bowel obstruction manage
This is treated conservatively with fluid resuscitation and nasogastric
decompression of the gut. The stomach contents should be aspirated using a
syringe, following which the bag should be placed on free drainage. Further
aspiration may be needed if required. Conservative management is successful in 65-
80% of cases and surgical intervention is only considered for those patients who do
not improve with conservative management
typical DIC bloods
. typically patients have thrombocytopaenia, prolonged PT and aPTT, low
plasma fibrinogen and an elevated plasma D-dimer. There may also be
microangiopathic abnormalities on the blood smear.
often sepsis trigger
why do anaesthetists apply cricoid pressure on intubation?
The cricoid cartilage is a complete ring; pressure on the front is transmitted to the
back, and this seals the oesophagus, preventing gastric contents in a patient who is
not fasted or has abdominal problems from passing higher up and possibly entering
the airway
morphine dosing for palliation of ca pts
The breakthrough dose should be one-sixth of the total daily dose. The current daily
morphine dose is 180 mg, hence MST continues at 90 mg 12 hourly and the
breakthrough at morphine 30 mg.
breakthrough dose = PRN dose
pericarditis and pericardial effusion ECGs
The history and ECG changes (widespread PR depression and ST elevation) are
strongly suggestive of pericarditis. A pericardial effusion would produce low-voltage
complexes on the ECG.
A 18 year old woman has 6 hours of severe dizziness and nausea. She says
that the room is constantly spinning round and she has vomited several times.
The dizziness is worse when she opens her eyes. She reports that her
hearing has not changed.
She has nystagmus with the fast phase to the left, which does not fatigue
vestibular neuronitis
single attack - don’t consider BPPV or vestibular migraine unless recurrent!

A 53 year old man has increasing abdominal swelling over several weeks. He
has developed severe abdominal pain over the past 12 hours. He drinks one
to two bottles of vodka per day.
He has jaundice, and has spider naevi and prominent veins on his abdominal
wall. His temperature is 37.6°C. His abdomen is diffusely tender.
