Ear pain or otalgia as a diagnostic problem presents commonly to primary health physicians. Otalgia may be primary, arising from the external auditory canal (otitis externa) or the middle ear (otitis media) or secondary.  As the sensory innervation of the ear is richly supplied by branches of the trigeminal, facial, glossopharyngeal, vagal nerve as well as upper cervical nerves it is not surp...

Irritable bowel syndrome is an idiopathic clinical entity characterised by chronic (more than six months) abdominal pain that occurs in association with altered bowel habits.

Australia has one of the highest rates of asthma in the world affecting about 11% of the population and in 2017/18 was responsible for 38,792 hospital admissions and 389 deaths, many of which may have been preventable. Asthma occurs when there is reversible expiratory constriction of the airways, especially the bronchioles and smaller bronchi, in response to various stimuli associated with a chron...

Thyroid nodules are common, in some ultrasound series at least 30% of adults are found to have nodules and 4-7% of adults will have a palpable nodule.  Whilst the overall risk of malignancy within a nodule is less than 5%, this is dependent on thyroid imaging reporting and data system (TI-RADS) which reflects features such as size of the nodule, presence of microcalcification, cyst complexity...

In this episode, we share an intimate conversation with Dr Shashi Manikappa who has spent the past 18 months in India’s heartland volunteering medical care to those affected by the Covid pandemic. Whilst over 400 million Indians have received at least one dose of vaccine to date, on the ground in India treatment protocols embracing the use of Ivermectin in combination with other drugs have gained...

Radiofrequency ablation (RFA) has revolutionised treatment for tachyarrhythmias and has become first line treatment for some tachycardias. Some arrhythmias are relatively common, atrial fibrillation for example affects up to 9% of our population over the age of 80 years and provides a very significant risk for thromboembolic stroke, haemorrhagic stroke as well as impairment of quality of life whil...

Atrial fibrillation is the most commonly experienced arrhythmia increasing in prevalence with age. It is estimated that 3 in 1000 under the age of 65 years have atrial fibrillation rising to 9% of people reaching the age of 80 years. The rate of stroke in untreated atrial fibrillation ranges from 5% per year with minimally associated risk factors up to 15-20% per year with associated risk factors...

As the Covid pandemic continues to spread around the world with over 187 million recorded infections and 4 million deaths, countries including Australia have embarked upon vaccination programs including the use of mRNA (Pfizer and Moderna), viral vector (Astra Zeneca), and subunit protein vaccines (Novovax). In Australia currently, less than 10% of our population have been fully vaccinated leaving...

Part 2. Heart disease affects one in six Australians with an AMI occurring every 10 minutes and accounts for one in four of all deaths, so primary and secondary prevention are very important considerations in relation to any patient presenting with heart disease or at risk of heart disease. Risk factors including family history, lipid abnormalities, diabetes mellitus, hypertension, smoking or thos...

Heart disease affects one in six Australians with an AMI occurring every 10 minutes and accounts for one in four of all deaths, so primary and secondary prevention are very important considerations in relation to any patient presenting with heart disease or at risk of heart disease. Risk factors including family history, lipid abnormalities, diabetes mellitus, hypertension, smoking or those with e...

Non-melanotic skin cancers and melanoma are the most common cancers affecting humans. At least two in three Australians will be diagnosed with skin cancer before the age of 70 years and the risk is higher for men than women. Whilst basal cell carcinomas and squamous cell carcinomas are more common they are not as lethal as melanomas which are referred to as Australia’s “national cancer”. Indeed in...

Chronic joint and muscle pain affects many millions of patients with more than one in four adults affected by some form of arthritis.
