Everyday Medicine with Dr Luke

The Peter Doherty Institute was the first Australian laboratory to establish a Covid 19 PCR test and diagnose the first SARS-Cov 2 infection on Australian shores, its research scientist is heavily involved in developing novel diagnostic tools applied across many areas of medical science and the institute plays a key leadership role in advising state and federal government on best medical practice....

Delivering hard news to a patient or their relatives and admitting error can be one of the most difficult duties encountered by a doctor. Significant effort is now spent in teaching young training doctors techniques and strategies to avoid miscommunication and uncertainty in undertaking this complicated task whilst also remaining emotionally engaged and empathetic to their situation. Rabow and McP...

Chronic pain affects about 1 in 5 people in Australia and is a common reason for patients to see their doctor and to seek treatment. As patients seek ever increasingly strong pharmacological therapies they may become increasingly depressed, fatigued and dislocated from society. In this episode we have a very interesting conversation with Dr Stephen Nutter, we follow Stephen’s journey from anaesthe...

Genetic testing for cancer is important for a small number of families at increased risk due to the inheritance of genetic mutations. Most commonly this involves the inheritance of breast cancer genes such as the BRCA 1 and 2 or colorectal cancer genes such as the Lynch syndrome genes. Although these only represent a small percentage of total cancers reported there is significant public interest i...

In the context of family cancer screening, genetic testing looks for specific inherited changes or variants in a person’s genes which may predispose them to an increased risk of developing a neoplasm. Harmful variants in some genes are known to be associated with an increased risk of developing specific cancers such as mutations to the BRCA 1 and 2 genes associated with breast and ovarian cancer a...

The ketogenic diet has recently become popular as an effective dietary approach to weight loss. The diet restricts carbohydrates to just 5-10% of total calories and relies on caloric intake from fats (55-60%) and proteins (30-35%) forcing metabolism to shift from gluconeogenesis to ketogenesis with the production of acetoacetate, beta-hydroxybutyrate and acetone – ketone bodies – as the usable ene...

Before proceeding, we apologise for the audio quality in this week's episode. Unfortunately, we experienced some technical difficulties and we will endeavour to resolve these problems in future episodes of Everyday Medicine . It is estimated that up to 80% of the population will experience back pain sometime in their lives with presentations from adolescent age to the elderly. Back pain is the thi...

Diabetic foot is the name given to the condition commonly experienced by people with diabetic peripheral neuropathy and results in an insensitive and often deformed foot. Found in both type I and type II diabetic patients (of which there are 1.8 million living in Australia-one new diagnosis is made every 5 minutes), even minor trauma in the diabetic foot may lead to the development of an ulcer. Th...

It is common in clinical practice to identify patients with impaired renal function as determined by diminished glomerular filtration rate and elevated creatinine. The decision to undertake thorough work-up and investigation of such patients or to observe and monitor, removing any potential offending nephrotoxic agent, is a clinical problem we address in this podcast with expert nephrologist Dr To...

Sodium is a major extracellular cation. Normal sodium concentrations range between 135 and 145 mmol/L. Alterations in sodium concentration, particularly hyponatraemia is the most common electrolyte disorder doctor’s encounter in clinical practice. Up to 20% of people admitted to hospital have hyponatraemia and it is estimated that 1.7% of population also have hyponatraemia. It was enlightening to...

The consequences of dementia with short term memory loss, visuospatial dysfunction, executive dysfunction, apathy, word-finding difficulty and apraxia is devastating both to the patient and family. It is estimated that 1% of Australians aged 65 years have dementia and that almost half of our population over 85 years have dementia to varying degrees. Alzheimer’s (60% of cases), vascular dementia (1...

Each year in Australia, over 125,000 of our more elderly population are admitted to hospital consequent to a fall. About a third of people over the age of 65 years fall each year and this figure rises exponentially with age. In up to 10% of falls, serious injuries such as fractures (a third of which are hip), soft tissue injuries and direct brain injuries arise. Falls and injuries from falls have...

Couples are said to be infertile if pregnancy does not result after a year of carefully timed sexual activity without the use of contraceptives and is estimated to affect up to one in six Australian couples. It is also estimated that male partners contribute approximately 40% to cases of infertility, the same percentage as women. In a third of couples, a combination of male and female factors both...

Altered uterine bleeding is estimated to affect 10-30% of women in midlife and constitutes about a third of outpatient gynaecological reviews. There are many aetiologies to consider including leiomyomas (fibroids), endometrial pathologies, polyps, malignancy, platelet dysfunction and coagulopathies. In this conversation, we are joined by expert obstetrician and gynaecologist Dr Peter Yong who comp...

The detection of colorectal polyps is of critical importance in the prevention of colorectal cancer. Studies have demonstrated that colorectal cancer arises from colorectal polyps in more than 95% of cases. Fortunately most polyps do not become malignant (less than 1%) and it is known that less than 5% of all colonic adenomas harbour malignancy. The National Bowel Cancer Screening Program has been...

Rectal bleeding is a very important clue to the possibility of serious internal colonic pathology. Whilst our approach to work up of patients with rectal bleeding is determined by the description of blood, the age of the patient and background history, it is extremely important not to overlook rectal bleeding as a possible early sign of a malignant polyp, premalignant polyp, colorectal malignancy...

Metabolic bone disease is common, it is estimated that about 4.75 million Australians have either osteopenia or osteoporosis. Osteoporosis affects up to 23% of women and 6% of men over the age of 50 with a markedly increased risk of minimal trauma fractures including hip fracture with increased morbidity and mortality. Osteoporosis is characterised by microscopic architectural deterioration of bon...

Centrally mediated abdominal pain syndrome is a chronic recurrent condition that is not related to bowel function, diet or definite organic pathology such as inflammatory bowel disease, diverticulosis, vascular syndromes nor neoplasia. It appears to be secondary to nerve sensitisation and may develop after significant emotional trauma or gastrointestinal infections. The syndrome may be highly intr...

Covid vaccine induced Pericarditis-Myocarditis Since the release of mRNA vaccines medical practitioners around the world have been receiving calls from patients complaining of chest discomfort typical of pericarditis some of these patients have also had associated ECG changes and cardiac enzyme elevation consistent with myocarditis. This phenomenon does not appear to be related to the non mRNA vac...

Polyps are discreet mass lesions that protrude into the intestinal lumen and represent a very important precancerous pathology to be identified and removed at colonoscopy. Up to 95% of adenocarcinomas arise from polyps, such cancers develop either after inactivation of the APC gene (for adenomas) or by KRAS mutation or BRAF oncogene activation with methylation of promoter regions for the serrated...

Up to 23% or more of Australians have varicose veins which may include small spider telangiectasias to large cosmetically challenging varicosities. In this episode we talk with phlebologist Louis Loizou who runs a very successful vein solution clinic in the community where he manages patients with all presentations of varicose veins, large, small, spider veins – he is able to find a solution for a...

Newfound freedom from lockdown in both Victoria and New South Wales will undoubtedly lead to greater COVID-19 exposure. Whilst widespread vaccination uptake has been achieved a significant number of adults and our children remain unvaccinated and vulnerable to the Delta strain. What can we expect from the health perspective for those exposed? What are the health departments rules governing exposur...

In this podcast we have a conversation with Gyu Lee who works with Victoria Alcohol and Drug Counselling Service as a harm reduction practitioner managing patients in the community who have developed addictions to both alcohol and drugs. Management techniques include close engagement with referred clients and an approach based on: · Behavioural modification · Pharmaceutical intervention · Job reha...

Globus pharyngeus in an intermittent or persistent non-painful sensation of a lump or foreign body in the throat. First described 2,500 years ago by Hippocrates who thought the condition was secondary to pressure on the thyroid cartilage from contractions of the strap muscles of the neck, we now know that globus is a relatively common condition representing up to 4% of ENT referrals and may be see...

Facial pain is a common presenting complaint in primary practice, in many cases the aetiology can be ascertained from a detailed history and examination,  however the source of pain may also be obscure including referred pain from the oral cavity as well as neurological, vascular and psychogenic disorders. We are joined today by experienced ENT surgeon Mr Adnan Safdar, Head of the ENT Unit at...
