In Pomegranate <<REWIND>> we go back to some classic episodes from the last ten years that have stood the test of time. The first throwback takes us back to 2017 with episodes 20 and 21 titled “Genomics for the Generalist.” While there’s been a flood of genomic discoveries since this story was first published, it’s still a good primer on fundamental concepts and everyday challenges for the physician advising a patient. The expert guests include a genetic pathologist, a clinical genet...

While waiting for COVID-19 vaccines to be rolled out, Australian jurisdictions adopted strong social restrictions to minimise community transmission of the virus. It’s estimated that together, these public health measures spared around 50,000 lives up to December 2022 and that vaccines saved three times as many again. While this public health response the pandemic is described as one of the most effective in the world it did cause unintended social harms and lingering resentment. Our leaders and...

A 62‐year-old man is undergoing a CT‐guided core biopsy of a lung nodule when he develops an iatrogenic pneumothorax. After admission to the Royal Adelaide hospital he has ongoing dyspnoea, oxygen desaturation, and chest pain not helped by a preexisting Chronic Obstructive Pulmonary Disease. The treatment for the patient’s symptoms doesn’t immediately go to plan but his care team apply a combination of recent technologies to bring the condition under control. Pomegranate [Case Reports] have been...

Médecins Sans Frontières has projects in more than 70 countries that might be affected by natural disasters, armed conflict or disease outbreaks. Its clinics see over two million emergency room admissions a year and another 16 million outpatient consults. Emergency Paediatrics consultant Josephine Goodyer and ID consultant Tasnim Hasan are two of more than a hundred Australians and New Zealanders who contributed to MSF’s missions last year. Between them they have covered practice settings as var...

A 75 year-old man with severe aortic stenosis is deemed unsuitable for surgery on the basis of a porcelain aorta detected with cross-sectional imaging. The patient had, a decade earlier, been diagnosed with hypertrophic cardiomyopathy after presenting with cardiac arrhythmia. A dual chamber ICD was implanted at the time for secondary prevention and other comorbidities were managed. The patient is now being considered for staged alcohol septal ablation (for the HCM) and transcatheter aortic valve...

The record for the longest space-flight is held by physician-cosmonaut Valeri Polyakov. Back in 1994-95, he spent 437 days on the Mir space station and grew 4 centimetres in height through elongation of his spine in micro-gravity. Polyakov had an uncomfortable ride back to Earth in the very precisely customised descent module. Microgravity also causes demineralization of weight-bearing bones that is faster than age-related decline. But the cosmonaut had worked out religiously for the entire miss...

In 2027, NASA’s is planning to land astronauts on the moon for the first time in 53 years with the expectation that there will be a permanent base there by the early 2030s. And the ever-humble Elon Musk reckons he’ll be sending people to Mars by then too. This has prompted a renewed interest in the prolonged effects of space travel on the human body, and a lot of fascinating research has been conducted aboard the International Space Station over the last two decades. The main objective risk to a...

A 72-year-old female presents to an Adelaide emergency department with bilateral eye pain and redness lasting several days. She has a history of hypertension, hypercholesterolemia and age-related macular degeneration for which she has received a range of medications. Anterior uveitis is identified as the proximal cause of the ocular pain but there are many possible aetiologies that require careful consideration. Pomegranate [Case Reports] have been developed to help Trainees rehearse diagnostic ...

Australia has just approved a second amyloid-targeting therapy for patients with incipient Alzheimer’s dementia. Lecanemab (Leqembi) now joins donanemab (Kisunla) on the Australian Registry of Therapeutic Goods but the impact of both has been modest in Phase III trials to date. After 18 months of therapy they delay progression of disease, as quantified on neurocognitive tests, by around 5 months on average. For some, the prolonged independence and dignity will justify the $60,000 to $80,000 a ye...

A 27-year-old male wakes up with weakness in the left arm and leg and gets himself admitted at Royal Adelaide Hospital. Shockingly, for an otherwise well young man with no significant medical history, a right middle cerebral artery acute ischaemic stroke is identified by CT angiogram. His condition deteriorates in hospital, and a mediastinal mass is discovered on review which gives a lead as to the distal cause. This conversation describes the expedient workup and methodical consideration of som...

Diabetic ketoacidosis can be life-threatening but there’s some variability in the way it’s managed between health settings. Intervention involves intravenous insulin administration, hydration, electrolyte replacement and treatment of the underlying precipitant. In a survey of practitioners from 31 different hospitals in Australia there was an even split between those organisations which followed a fixed rate insulin infusion protocol, usually based on bodyweight, or a variable rate infusion prot...

Pomegranate Health has been streaming since June 2015, so we’re going to share a few more classic eps from the last ten years. First up, presenter Mic Cavazzini digs deep to find the origins of the pomegranate, featured not just on this podcast but on the crest of the RACP. The journey starts 500 years ago at an unlikely place, the marriage of Henry VIII and the first of his six wives. You’ll find much of the pageantry reproduced at the web page. We then hear from the wonderful staff at Marrabin...

Cerebral microbleeds are a finding on MRI that are usually asymptomatic. There are two main aetiological pathways, one occurring as a result of uncontrolled hypertension and the other from the accumulation of amyloid-beta peptide. The link between cerebral amyloid angiopathy and Alzheimer’s Disease is not understood and even the impact that cerebral microbleeds more generally have on cognition. For the study discussed today, clients of an Australian memory clinic were retrospectively assessed fo...

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 ...

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...

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 impr...

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...

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 liste...

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, re...

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. Guest Dr Shaun Evans, FRACP (Royal Adel...

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 physici...

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...

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, ma...

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 ...

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 majori...

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 in...

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 ...

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; E...
