[Case Report] 46yo with psychosis and cold intolerance
A 46-year old man is admitted to hospital following a first time presentation of psychosis that involved barricading himself inside a neighbour’s home. At admission he appears disorganised with slow movements and speech. His rambling reveals bizarre delusional beliefs of a paranoid and persecutory nature. At moments he shows aggression towards staff but when examines reports occasional dizziness and an intolerance of cold. Physical examination reveals cool peripheries, sparse axillary and pubic hair, and soft adult-sized testicles. The investigating team suspect hypothyroidism and a complex series of investigations and therapies follows.

Ep132: Ten Years of Pomegranate Health
Pomegranate Health marks ten years of podcasting since its launch in June 2015. This episode will be one of two samplers that dip into the back catalogue of 131 episodes to showcase some of the most compelling stories. You’ll hear how podcast themes are identified from all the domains of medicine and professionalism. And a little bit about the motivations of long-time producer and presenter, Mic Cavazzini.
Pomegranate Health has several thousand listeners in over 150 countries. Three quarters of listeners are, predictably, in Australia and Aotearoa-New Zealand, but a full 14 per cent are located outside the traditional anglosphere. RA...
Ep131: The semantics of CPR
In this podcast we discuss low-value care that has emerged from a decay in the specificity of the terms “cardiac arrest” and “cardiopulmonary resuscitation.” Patients who experience cardiac arrest in hospital are rarely more than a minute or two away from defibrillation. But the proportion of shockable rhythms in these patients is low as the heart has typically stopped after the decline of other systems. In such conditions, chest compressions are more likely to cause unnecessary trauma than improve survival outcomes.
As retired UK palliative care physician Kathryn Mannix explains, “cardiac arrest” was originally reserved for unexpected events in rel...
Ep130: "The motherhood penalty"
Despite filling more than half of places in Australian medical schools, women represent 45 per cent of all medical practitioners and just 36 per cent of specialists. Female representation dwindles further in many areas of clinical leadership, prompting what has been termed a “leaky pipeline”. It has been reported that women would progress at similar rates to men, and achieve similar remuneration, were it not for the time taken out from the profession to raise children. In this podcast we discuss what it would take to mitigate this so-called “motherhood penalty” through policy, workplace culture and better distribution of labour in the home...
[Case Report] 65yo with ST elevation during AF ablation procedure
ST elevation is clearly a worrying finding that can herald life-threatening conditions, such as ST elevation myocardial infarction. But not all ST-elevations are created equal, and Trainees would benefit from considering a broader number of causes for this presentation. In today’s podcast the team will discuss a case of ST elevation observed in a 65-year-old female during the routine elective procedure of atrial fibrillation ablation. A range of pathophysiologies is discussed that can help listeners work though the differentials in a systematic way.

Ep128: Brushing off the cobwebs
There is evidence that six months or more off the job leads to some loss of practical skills and knowledge and certainly, many doctors report a loss of self-confidence. People take time out from medical practice for many different reasons but career breaks to raise children are more common than ever before. Senior staff at Sydney Children’s Hospital have developed a day-long workshop to help medics brush off the cobwebs before they return to practice. It involves rehearsal of specific skills, refreshers on calculation and interpretation tasks and a high-fidelity critical care simulation. Just as importantly, there is op...
[Case Report] 74yo with dyspnoea after AF ablation
In this episode we hear about an emergency presentation to a South Australian hospital, of a 74-year-old male with shortness of breath. The curve ball is that he had undergone ablation for drug-refractory atrial fibrillation less than two weeks prior. This discussion gives an overview of developing technologies for AF treatment and developing knowledge about the possible complications. We also have some multiple choice questions to test your understanding.

Ep126: Trying times for Māori medics
In Aotearoa-New Zealand, the proportion of doctors identifying as Māori has doubled from where it was a decade ago to over 5 percent. But there is still a long way to go before the workforce is representative of the broader population which is 17 percent Māori.
The Auckland and Otago Medical Schools have in recent years turbocharged their intake of Māori and Pasifika students but these graduates don’t seem to have trickled through to the RACP in great numbers. Just 3.5 percent of general physicians and 4.8 percent of paediatricians identify as Māori, and Pasifika doctors make u...
[Case Report] 52yo with hand clumsiness after Chiari operation
This case report comes to you from Brigham and Women’s Hospital in Boston, a huge teaching hospital that serves the Harvard Medical School. The 52-year-old female presented with clumsiness and paresthesia of the right hand that had persisted for several days. She also had a headache and three weeks prior to presentation had undergone a suboccipital craniotomy for a Chiari I malformation. To complicate things, there was a past medical history of migraines and a family history of a Factor V Leiden mutation. The identified diagnosis is one in which evidence is limited for aspects of management, and th...
Ep124: Pleural medicine comes of age
Professor Gary Lee established the first dedicated pleural service in the southern hemisphere in 2009, at the Sir Charles Gairdner Hospital in Perth. He says that pleural disease has finally come to be regarded as an area of subspeciality interest in its own right, not just a complication of other comorbidities. In this podcast he presents a potted history of key developments in the management of pleural effusion in particular.
This is diagnosed in about 60,000 people every year in Australia, mainly as a result of infection or malignancy. With mentors in the UK, Professor Lee conducted some of t...
[Case Report] 42yo male with fever following liver transplant
This case report describes a 42-year-old male from Arizona with a complex course characterised by fever following an orthotopic liver transplant. A general approach to fever in the post-transplant patient is discussed, along with specific considerations regarding travel in post-transplant patients or those on immunosuppressants for other indications. A/Prof Camille Kotton and Dr Simran Gupta from the Massachusetts General Hospital and Brigham and Women’s Hospital take listeners through the case and related issues in a step-by-step manner at a level targeted for trainees and generalists.

Ep122: Funding pan-cancer therapies
In the previous episode we heard how some rationally-designed therapies work on almost any cancer with the right molecular signature. Tumour-agnostic medications could be godsend for patients with rare cancers which have classically been overlooked by drug developers, and those with advanced cancers of unknown origin. 15,000 such patients have undergone comprehensive genome profiling of their tumours through the organisation, Omico. In this podcast, Omico’s founder explains that while the majority have received recommendations about matched therapies, clinical trials are typically the only way to enable access. Professor David Thomas discusses why Australia’s Health Technology Assessment process appears to b...
Ep121: Precision oncology explained
The genomic understanding of cancer has transformed a tissue-based classification model that had been dominant for 150 years or more. The last three decades have seen highly targeted therapies developed at blistering pace, and unprecedented improvements in patient outcomes.
To date, these advances have been focused on more common cancers. The financing model for drug development means that rare cancers get overlooked, given the small pool of potential buyers relative to the costs and risks of investment.
However, the molecular targets characterised in more common cancers are often found in cancers of a different histotype. As su...
[Case Report] 35yo male with proximal weakness and skin changes
This case report describes a 35-year-old Caucasian male presenting with 5 weeks of progressive weakness in the proximal limbs and trunk and associated changes to the skin. The man was previously well and not taking any regular medications. There are many pathways this undifferentiated patient could go down. Consultant physician, Professor Josephine Thomas demonstrates a systematic way to work through the differential diagnoses as would be expected in a long-case presentation for basic physician training exams. She's the Clinical Dean for the Adelaide Medical School at the Northern Adelaide Local Health Network.

[Case Report] 47yo with rapidly progressive respiratory failure requiring ECMO
In 2019 a man was referred to Royal Adelaide Hospital with worsening breathlessness and a productive cough. He was a 47 year old electrician with a history of tobacco smoking who’d been well before the onset of symptoms. Over a couple of admissions the patient’s condition progressed to type 2 respiratory failure. While the ultimate explanation for this presentation was a bit of a unicorn, the dramatic escalation of examinations and interventions runs through some textbook respiratory medicine; ECMO, infectious diseases, bronchoscopy, CT, interpretation of blood gases and the alveolar gas equation, stenting and ultimately transplantation. This is discussed in the...
[Journal Club] Thrombolysis up to 24hr after ischaemic stroke
Thrombectomy for acute ischaemic stroke has undergone great advances in the last decade, but the expertise and technology is restricted to tertiary hospitals. Outside of large metropolitan centres, thrombolytic treatment can buy a patient time, but for almost 30 years the first line agent has remained unchanged.
Alteplase is an analog of the human tissue plasminogen activator which activates plasmin to dissolve fibrin blood clots. For many years it was assumed that alteplase should be administered within 3 hours of symptom onset, thus it was a big deal when in 2008, research showed that that window could be safely broadened o...
[Case Report] 48yo with diarrhoea and lymphadenopathy
This podcast follows the case of a 48-year-old male with a 3-month history of diarrhoea and associated lymphadenopathy. A complex constellation of symptoms accompanies this presenting complaint, along with a key radiological finding that enabled the treating team to arrive at the correct diagnosis. Can you arrive at the correct diagnosis before the treating team? This case was managed at the Queen Elizabeth Hospital and is presented by Dr Andrew Vanlint from the Northern Adelaide Local Health Network and University of Adelaide.

[Guest Lecture] Fighting hepatitis C in prisons and the community
This recording comes from the launch of the 2nd Monitoring and Evaluation Report on Hepatitis C Elimination in NSW. The work was conducted through the Kirby Institute under the guidance of infectious diseases specialist, Professor Greg Dore. As presented in this seminar, data show that the state is on track to meet the 2025 target set by NSW Health, and the national target for 2030, but there have been surprises along the way that have required an adaptable approach to surveillance and intervention.
This is particularly true in correctional settings which typically have high rates of hep C transmission d...
Ep115: One day as a nuclear medicine registrar
Dr Karan Singh loves his job as a registrar in nuclear medicine but he thinks there isn’t enough exposure to the specialty during medical school and basic training. In this podcast we spend a day in his department at Prince of Wales Hospital Sydney and get a taste of the many different referrals that come his way; a bone scan for a young man experiencing leg spasms after recovering from a car crash; myocardial perfusion imaging for an elderly gentleman with coronary artery disease; staging for prostate and breast cancer; and radiation therapy for a toxic multinodular goiter.

[IMJ On-Air] Understanding readmissions better
The LACE index is a prognostic algorithm for predicting the likelihood that a newly discharged patient will come back into hospital within 30 days because of complications. Today’s IMJ paper describes a validation of the LACE index in a regional Victorian setting. Identifying patients who are at risk could allow for better targeted care at the first admission, reducing harm to patients and inefficient use of healthcare resources.
The researchers also tested a novel classification tool for scoring which readmissions are avoidable and which are just an unfortunate outcome of the patient’s illness. This could help more a...
[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.

[Case Report] 32yo with abdominal pain two years after pancreas-kidney transplant
This case report has been developed by Trainees, to assist their peers with preparation of long-case presentations. It is not a fully-vetted Education resource but a “passion project” from editors of the Pomegranate Health podcasts.
The case is that of a 32-year-old woman presenting with constant and dull abdominal pain that had been sudden in onset. The pain is accompanied by nausea and vomiting but bowel habits were unchanged. The patient has a history of type 1 diabetes and a simultaneous pancreas-kidney transplant two years prior to the presentation. There is no history of rejection of pancreatitis and serum...
Ep109: Cultivating a rural workforce
Australia is a big continent and sparsely populated continent. 28 percent of Australians live in areas classified regional, rural or remote and their access to health services is much more limited. It’s estimated that between 2009 and 2011 there were 19,000 excess deaths in regional and remote areas as compared to the major cities. No doubt, socioeconomic disadvantage is factor in that mortality gap, but inequitable access to healthcare is also a major driver.
In this podcast we focus specifically on the shortage in health practitioners in the regions. Even in regional centres, the density of physicians by pop...
[Case Report] 68yo with cardiometabolic risk factors and transient monocular vision loss
Pomegranate [Case Report] is a Q&A style podcast developed by trainees, for trainees. In our debut episode, we hear about w a who man presented to the emergency department reporting sudden onset vision loss in his right eye lasting several hours. He was 68 year old with a history of type 2 diabetes mellitus. Three differential diagnoses being considered were optic neuropathy, vitreoretinal disease, or corneal oedema following from potential uveitis. In this podcast consultant ophthalmologist, Dr Sumu Simon, walks through an approach to this presentation and an exploratory therapy.

[Journal Club] Baricitinib immune therapy for new onset type 1 diabetes
Type 1 diabetes has a very high treatment burden in terms of direct costs, inconvenience and lost productivity for patients and their carers. Further, all the glucose checking, hormone replacement and consults don’t abolish the vascular complications associated with poor glycaemic control. Only in the last few years has it been possible to pharmacologically alter the course of type 1 diabetes and other auto-immune diseases without generating intolerable side effects.
Teplizumab is an antibody to CD3 which was presented to the world in 2019 as delaying the onset of type 1 diabetes in high-risk individuals thanks to its protective effect on...

Today’s guests are the hosts of This Medical Life, a wonderful podcast that delves into the archives of medical history. Dr Travis Brown describes the period after World War I when the Spanish Flu was killing tens of millions around the world. In the USA, whiskey was thought to be a powerful prophylactic but distribution was not an easy thing. Later in the episode (22min) is the equally unlikely tale of how the pomegranate made its way from ancient myth onto this podcast by way of Henry VIII and some mystical symbolism.

Ep105: When parents and paediatrics clash
Last November an NHS Hospital Trust in Nottingham sought permission from the UK High Court to withdraw life support from a seven-month old girl called Indi Gregory. The devastated parents did not want to give up on her although they were advised there was no hope of treatment for her profound developmental disability. The family and the medical teams returned to court two more times, right up to the day that Indi was to be extubated.
Conflicts over care have always existed but their frequency has increased as medicinal advances present more options for intervention even in t...
[IMJ On-Air] Is the jury still out on omega-3 supplementation?
The theory that certain fatty acids are essential to the diet and associated with reduced cardiovascular risk has been controversial since it was floated in the 1950s.
In 1971 Danish researchers published the results from a cross-sectional study of Inuit people living on the west coast of Greenland. They ate a fish-based diet rich in polyunsaturated fatty acids known as omega-3s, which were found in their tissues along with much lower levels of pre-β-lipoprotein and plasma-triglycerides when compared to controls.
That association between a fishy diet and lowered cardiovascular risk has been replicated in mult...
[IMJ On-Air] HepatoCare: a model for palliative and supportive care in advanced cirrhosis
Median survival for patients diagnosed with advanced cirrhosis is around 2 years and quality of life is poor. Fewer than a quarter of such patients receive referrals to palliative care and advanced care plans are also rare. Existing research from abroad suggests that hepatology staff aren’t familiar with referral criteria and assume that palliative services become involved only at the very end of life.
To try and reduce barriers to referral, clinicians at Royal Brisbane Hospital developed a model called Hepatocare. They adapted a palliative care referral algorithm to include cirrhosis specific markers and continuity of care betw...
Ep102: Staying on script with semaglutide
Semaglutide, branded as Ozempic or Wegovy, is an analogue of glucagon-like peptide 1 which has glucose-dependent effects on insulin secretion. In this episode we discuss how semaglutide performs as an antihyperglycaemic agent compared to previous GLP-1 analogues and the soon-to-be launched tirzepatide. This dual agonist also binds receptors to glucose-dependent insulinotropic polypeptide, GIP.
GLP-1 and GIP are incretin hormones, secreted after food intake and involved in regulating gastric motility and appetite. The analogue therapies have resulted in weight loss of 10 to 20 percent in trials on patients with obesity or other weight-related comorbidities. For various reasons, however, they remain...
Ep101: Setting the standard for workforce wellbeing
We’ve known for a decade that about 50 percent of doctors meet the criteria for burnout, and the figure is up to 70 percent among trainees. But organisations have been left to come up with their own solutions to this, the result being that many simply offer band aid solutions rather than systemic ones. Unforgiving work conditions pose a problem for both recruitment and retention of staff to the health workforce. The New Zealand Health Department, Te Whatu Ora, forecasts that within ten years supply of doctors, pharmacists and nurses will fall short of demand by 14 to 18 percent. In response th...
Ep100: Conversations with ChatGPT
This is the final episode in a five-part series about artificial intelligence in medicine. We start by weighing up the costs and benefits of automation in a health system that’s increasingly pushed beyond capacity. One of the biggest time sinks for health practitioners is filling out and searching through medical records. Some of this could be performed by natural language processors which are becoming more accurate thanks to deep learning.
The power of large language models has been demonstrated by the meteoritic uptake of ChatGPT and doctors are among those who have used it to summarise liter...
Ep99: When AI goes wrong
This is the fourth part in a series on artificial intelligence in medicine and we try and unpick the causes and consequences of adverse events resulting from this technology.

He breaks down those that were caused by errors in the machine learning algorithm, other aspects of a device or even user error.
We also discuss where these all fit in to th...
[IMJ On-Air] A tiger in the mallee: Victoria’s JEV cluster
On the 28th of January 2022 a 75-year-old man was admitted to the regional Albury Wodonga Health Service with a high fever and Parkinsonian symptoms. The patient spent over a week in intensive care, but brain scans did not reveal an obvious aetiology and assays for a range of pathogens came up negative.
When serology eventually revealed the presence of antibodies against Japanese encephalitis virus this became only the second ever locally-acquired case on Australia’s mainland. Even more startling was the fact that the previous one had been way back in 1998 in Cape York, far north Queensland.

This is the third part of a series on artificial intelligence in medicine. Previously we explained how to train and test machine learning models that assist in decision-making, and then how to iron out ergonomic friction points in the clinical workflow. We’ve mentioned how deep learning neural networks are more capable than classical models at dealing with big noisy data sets, but also that the reasoning they use to solve questions asked of them might be inexplainable users.
This creates a certain unease among clinicians and regulators like Australia’s Therapeutic Goods Administration. According to some, we jus...
Ep96: The ergonomics of AI
The allure of having devices and tasks assisted by artificial intelligence is that they will help overcome some of the natural limits of human cognition with regards to working memory and attention. And in helping with the mundane tasks, AI can buy clinicians back time to spend with the complex patients who really need it. But the way all this pans out will really depend on how seamlessly the machine learning devices fit in with the clinical workflow. Which aspect of clinical decision-making do they support and how are the consequences of error mitigated? Only a small fraction of...
Ep95: Machine Learning 101
AI-assisted healthcare is reaching maturity in many applications and could alleviate some of the capacity gap increasingly faced by health systems . Over the next three podcasts we focus on artificial intelligence tools designed to assist directly with clinical practice.
Most commonly reported on are the algorithms capable of pattern recognition on medical images, that in some settings perform as well or better than expert diagnosticians at classifying disease. AI models have also been developed to perform regression analyses more complex than classical risk stratification aids.
The standard statistical algorithms used to solve these problems struggle w...
Ep94: Facing up to racial bias
In today’s podcast we try and understand the impact that racial bias makes on variation in clinical care. For example, racialized patterns in the use of analgesia were brought to light over 20 years ago but are still occurring today. In research from the UK published in March it was found that women of African or South Asian extraction were significantly less likely to receive an epidural during vaginal birth, or instrumental assistance with the delivery. The direct reasons for this variation were not revealed by the study, and could simply reflect the preferences of different cultural groups. But if...
