Pomegranate Health
Pomegranate Health is a podcast about the culture of medicine. You'll hear insights from clinicians, researchers, and advocates as they tackle important questions — like how to make difficult clinical and ethical decisions without being influenced by bias, how to communicate better with patients and colleagues, and how to provide healthcare that’s both efficient and fair.
If you're a Fellow of the RACP, time spent listening can be counted toward your CPD hours. And if you're a Basic Physician Trainee, the [Case Report] series can help you prepare for your long case clinical exams.
This is also the home of [IMJ On-Air], featuring authors from the Internal Medicine Journal sharing their latest research. The [Journal Club] episodes give RACP researchers a space to talk through their work published in other academic journals. And for Basic Trainees, the [Case Report] series can help you prepare for your long case clinical exams.

[Case Report] 58yo with acute myeloid leukaemia and diplopia
This podcast follows the case of a 58 year old man who presented to the haematology department at Flinders Medical Centre with intravascular coagulation and leukocytosis. He was diagnosed with acute myeloid leukaemia and treated on standard cytarabine and daunorubicin combination therapy. Nine days after initiation, the patient developed painless diplopia and ptosis, and the story is picked up with a referral to the neurology department.
Guests
Associate Professor Stephen Bacchi (Lyell McEwin Hospital; University of Adelaide)
Dr James Triplett FRACP (Flinders Medical Centre, consultant neurologist)

Painless progressive mononeuritis multiplex secondary to AML associated neuroleukemiosis [J Neuroimmunol. 2023]
(1) Chemotherapy can have neurological complications, including chemotherapy induced peripheral neuropathy (e.g., oxaliplatin).
(2) A third (oculomotor) cranial nerve palsy has multiple possible causes, which can be divided into painful vs painless causes, and compressive (classically with pupillary involvement) vs non-compressive (can spare pupil, as with microvascular insult) causes.
(3) Conduction block is shown by a significant reduction in compound muscle action potential, between proximal and distal stimulation, the criteria for which varies by nerve.
(4) Ascertaining whether conduction block occurs at compressible vs non-compressible sites can be a useful distinguishing feature for the various possible causes e.g. including compression, demyelination, and ischaemia, and
(5) Mononeuritis multiplex, while classically associated with a vasculitic neuropathy, has a number of causes, including leukaemia. This is the very rare condition known as neuroleukemiosis.
