In the current climate, there is good reason for people to worry about losing their GP. If anecdotes are to be believed, COVID is proving to be the final nail in the coffin for some doctors in their decision to call it quits – dubbed The Great Resignation.

EDITORIAL POLICY

I’ve banged on for years to anyone who will listen how outrageously inadequate the financial remunerations are via the MBS, proportion to the training (past and ongoing), and the ever-expanding responsibilities that rest with GPs. Money isn’t everything, but it’s not nothing either. Contributors should be aware the publisher asserts the right to syndicate material appearing in Medical Forum on the mforum.com.au website. Contributors who wish to reproduce any material as it appears in Medical Forum must contact the publisher for copyright permission.

And if surveys are to be trusted, at least one-fifth of current GPs are seriously considering pulling the pin in the next 12 months.

Seriously, I dread losing my doctor – not him leaving this mortal coil, but the R word – retiring. (Dr John you’re too young anyway).

Only the fact that the volatile financial market has bitten into superannuation savings might deter some from retiring right now. That’s not to say that general practice is not a rewarding career, although I use the word ‘rewarding’ with caution.

I have already told my GP he is not allowed to retire, but Dr John, if you’re reading this, that means you. (I have prepaid your AHPRA registration fees for the next 10 years, so there is no wriggling out of it.)

While immunotherapy has emerged as a major weapon in the battle against non-small cell lung cancer, which makes up 80-85% of all lung cancer diagnoses, it can also result in severe side effects for patients.

However, principal midwifery officer at the Australian College of Midwives, Kellie Wilton, has hit back saying mothers should not be made to feel guilty about their pain relief choices and suggested hospitals could introduce nitrous oxide destruction systems to allow for its ongoing use. When these systems were introduced in Swedish hospitals, the carbon footprint from the gas was halved.

ECU & WACHS unite ECU and WA Country Health Service have signed a memorandum of understanding to develop interconnected regional clinical education, teaching, research and initiatives in the South West, including opportunities for internships, graduate employment and new course development.

Nitrous oxide is used by more than 50% of Australian women to relieve pain in labour, followed by epidurals (nearly 40%) and opioids (12%), according to the AIHW. However, its carbon footprint (representing 6% of global gas emissions, with 1% due to health care) has led to a debate whether it should be replaced with other methods of pain relief.

Anaesthetist Professor Bernd Froessler and colleagues compared patient notes for all 243 women birthing at Lyell McEwin Hospital over a seven-week period in March/ April 2020, half of whom did not have access to N20. They found that although opioid use “significantly increased” when N20 was withheld, there was no increase in epidural use and no change in labour duration, caesarean section rates, birthing complications or newborn alertness.

As the health system scrambles to reduce emissions, attention has turned to nitrous oxide in the labour suite. A study out of Adelaide is saying that birthing women denied nitrous oxide to relieve labour pain during the COVID-19 pandemic have turned to opioids instead, without any adverse outcomes for mother or child.

At least 74% of those treated will experience immune-related adverse reactions and up to 21% of those will develop grade three or four toxicity, which can lead to lifelong complications affecting the skin, gut, liver or endocrine system.

Murdoch Children’s project lead Professor Andrew Steer said the study would investigate how many children got sore throats, what was the most common cause and how they could change during different seasons of the year. The information collected will help inform how a vaccine could be used to prevent a wide range of illnesses caused by Strep A, including impetigo, septicaemia, rheumatic heart disease and kidney disease.

Former AMA national president Dr Omar Khorshid and WAPHA CEO Learne Durrington are the WA members on the Strengthening Medicare Taskforce.

Silverchain’s Dr Robyn Rayner, Professor Keryln Carville, Joanna Smith and Cate Maguire’s research article on a skin tear assessment tool has been recognised at the Coloplast Biatain Literary Awards.

More than 1000 children are being sought for a study to learn more about sore throats and how best to prevent them. The STAMPS study, led by Australian Strep A Vaccine Initiative (ASAVI) partners – Murdoch Children’s Research Institute (MCRI) and the Telethon Kids Institute – are recruiting 1050 healthy children, aged 3-14 years, in Melbourne and Perth.

ASAVI co-director, Telethon Kids Institute Director Professor Jonathan Carapetis, said a Strep A vaccine was urgently needed.

IN BRIEF

Strep A infections disproportionately affect young children, the elderly, pregnant women and Indigenous Australians. Rates of rheumatic heart disease among Indigenous populations in northern Australia are some of the highest in the world. There is currently no vaccine available to prevent Strep A and infection can only be treated with antibiotics.

“A safe and effective Strep A vaccine is an important and practical solution for disease control, which will do so much to not only close the gap in Indigenous health in Australia but ease the burden of diseases caused by Strep A globally, particularly in developing countries,” he said.

Predictable seasonal patterns of influenza viruses worldwide is the backbone of worldwide influenza surveillance systems and vaccination programs over the past several decades. However, the public health measures implemented worldwide to contain the SARS-CoV-2 virus (between early 2020 and early 2022) resulted in a dramatic impact on the circulation of influenza and other respiratory viruses (Table 1). The total absence (0) of influenza detections between March to June 2021, is in stark contrast to 3296 detections in 2019 (Table 1).

The RACGP has called on the Federal Department of Health to allow GPs to approve access to subsidised glucose monitors for their patients. Not only is managing patients with type 1 diabetes within a specialist team well within the scope of GPs, it gave greater access for people with type 1 diabetes to essential monitoring and effective management of their condition, said college president Adj/Professor Karen Price. “On 1 July this year, the government announced that access to subsidised continuous glucose monitoring and Flash GM products for patients with Type 1 Diabetes would be expanded via the National Diabetes Services Scheme (NDSS). However, the NDSS outlines that health professionals authorised to certify continuous and flash glucose monitoring access forms are those for whom diabetes is the main scope of their practice.

“There is no logical explanation why other members of a health-care team are authorised, but GPs are excluded. Not only is it insulting to GPs, it creates an unnecessary barrier to patient access for something that could make a real difference in managing their health.”

In another RACGP push, a petition has been raised to allow practice nurses to give flu jabs under the supervision of a GP in general practices. The petition urges the government to create a new MBS item number for this purpose, based on existing item 10988 (an immunisation provided to a person by an Aboriginal and Torres Strait Islander health practitioner).

Philosophical worldviews shape our perceptions of relationships, ethics, politics, aesthetics and the environment. At this point in human history, there seems to be a shift in the philosophical orientation we have to the world. A dominant world perspective until now might have been called dualism. This view has given rise to all the examples of ‘them’ and ‘us’ such as tribalism, war, colonialism, political parties and domestic violence. The dualistic perspective also separates the mind from body (the perspective that our consciousness and the stories and memories we carry are somehow housed in a separate domain called mind, separated from the rest of our Perhapsbody.)we are transitioning from a Newtonian, interactional, machinelike dualistic perspective of how the world works to one where there is a more complex flowing relationship between humans and the other aspects of the environments in which we are embedded. Evidence for this shift (on the macro-scale) includes the general acceptance of human-induced climate change and other forms of environmental degradation and (on the micro-scale) the recognition of the importance of the microbiome to our health. Historically, it has been an error or at least a blindness to the fact that humans are part of the milieu in which we exist and that we affect that milieu and are inescapably influenced by it.

“I thought about doing law, but it didn’t really interest me,” Talila says. “Plus, I was more engaged in science in high school. I also knew there was a huge discrepancy between the health of Aboriginal people and non-Aboriginal people. Medicine seemed like the place where I could make the biggest impact. I chose psychology as my major in my science degree which has worked in well.”

Luckily for her patients, she didn’t enjoy the media and communications course and not long after, decided a switch to medicine, with a strong feeling it would better satisfy her goals around social justice, health care education and research.

In May, Aboriginal health service South Coastal Babbingur Mia announced Talila’s appointment to their team. In a landmark appointment, she is the first Aboriginal GP to work there and possibly one of the first to work in the Rockingham and Kwinana “Babbingurdistrict.

“It also means a lot doesn’t need explaining so the patients don’t need to go through certain cultural and social factors as they are understood. We are providing a service with a deep understanding of where that person is coming from in a judgment-free way.”

“Being able to use my position to help vulnerable members of our community – Aboriginal and non-Aboriginal – is an important part of my job,” says Talila. “I enjoy providing comprehensive care and a needed service. Doing this work really aligns with my clinical goals and values. It’s challenging work.”

Talila says quality of care is a barrier for Aboriginal people seeking medical help. A long history of suboptimal care, judgment by authorities, health providers and hospital systems are just part of the complex puzzle. While she knows it takes time for the relationships to be rebuilt, there are many health professionals working to improve the “Havingsituation.Aboriginal health professionals and providers creating culturally safe health care spaces definitely is part of the solution – but all health professionals and services should be able to provide this. People should be able to access any health care and feel safe.”

For Aboriginal and Torres Strait Islander people born 2015-2017 in WA, life expectancy was estimated to be 66.9 years for males and 71.8 years for females, around 13.4 – 12.0 years less than the estimates for nonIndigenous males (80.3 years) and females (83.8 years).

In 2017, the leading causes of death among Aboriginal and Torres Strait Islander people were coronary heart disease, diabetes, intentional selfharm and lung and related cancers. In 2011, Aboriginal and Torres Strait Islander people living in WA compared with those living in NSW, Qld and the NT, experienced the second highest rate of total burden of disease (BOD) (498 per 1,000), highest non-fatal BOD (193 per 1,000) and second highest rate of fatal BOD (305 per 1,000). In 2011, Aboriginal and Torres Strait Islander people experienced total BOD at 2.8 times the rate of nonIndigenous people, for fatal BOD, 3.6 times higher and non-fatal BOD 2.0 times higher.

In 2016, around 14% of babies born to Aboriginal and Torres Strait Islander mothers were of low birthweight (LBW), compared with 6.5% of babies of non-Indigenous mothers.

In 2015-2017, after age-adjustment, the death rate for Aboriginal and Torres Strait Islander people in WA was 12 per 1,000. This was 2.1 times the rate for nonIndigenous people.

Now, working more regular and known hours, Talila says family time is the priority. She enjoys cooking –particularly Lebanese food and the odd novelty birthday cake – and reading, often choosing medical humanities titles.

“I’m married and if it wasn’t for my husband and his support, I would have not gotten through it. He held down the fort as a stay-at-home dad when I did long days and shift “Whenwork. I decided to do medicine, there were definitely discussions about how it would look and work, knowing it would be long term. My hat is always off to families who have two parents working fulltime. It’s not easy and the cost of childcare is not conducive.”

Mia is where I feel like I will be able to make a difference. As an Aboriginal woman, we are providing an opportunity for culturally safe care. Cultural safety is important in seeing our clients in a holistic way that meets patient goals and needs,” she says. “It ensures that we as health professionals nurture and celebrate culture, family, emotions and spirit as much as we care about physical and mental health. It means that we provide the best and most comprehensive care and ultimately achieve better outcomes for the individual and the community.

As part of encouraging more Aboriginal people to become involved in health care, Talila says she’s always happy to chat to people who show an interest. She speaks to more females but suggests that might just be selfselection in them seeking her out. Questions about being a mother are some of the most common, like how do you balance work and family in your reproductive years?

Talila is also particularly close to her grandmother and has been able to make up for the lost time of living in Sydney. She visits once a week and they chat, run errands or might draw together. Her grandmother has a particular love for op shops.

“We talk about all sorts of things. I really value our time together and value her knowledge. Just hearing about her life experiences, which are so different from mine. I can’t have learnt about what she shares with me in any other way.

According to the Australian Indigenous HealthInfoNet's Overview of Aboriginal and Torres Strait Islander health status in Western Australia, key facts for WA include:

Talila started with a fortnightly residency, which will expand as patient numbers grow. To date most of the women she has seen have come to her because in the past they have felt unheard or not been given the appropriate time.

She’s definitely a glass half full person and a high level of empathy can at times affect her deeply when dealing with patients, their health issues and life stories. It’s balanced with a sense of efficiency, being able to prioritise tasks and having strong communication skills.

“A lot of that is more reflective of a system which doesn’t necessarily value time with patients. I also have a good knowledge of the services and benefits available to patients, so am able to help with that and to navigate the system.”

Recuperating after a hospital stay can be tough for anyone, but for people without a home, finding a place to recover is even more challenging.

Some doctors wanted to test residents for drugs and alcohol, but he wasn’t keen on a monitoring or punitive approach or excluding people because of drug use or mental health

“That’s why they end up homeless in the first place. They don’t get treated by the mental health people because they’ve got a drug and alcohol problem, and the drug and alcohol people won’t treat them because they’ve got a mental health problem.”

Homeless Healthcare was the first service of its kind nationally, becoming the largest specialist homelessness primary care service in Australia, and since 2008 it has supported more than 5000 people experiencing homelessness through a range of clinics and out-reach services. Its medical respite centre, which opened its doors last October, provides 20 short-stay medical beds to care for homeless people after a hospital presentation or admission in the Perth metropolitan area.

With the State Government providing $4.4 million over two years, the centre was designed to offer post-acute care in a safe environment, while also linking people to services to help break the cycle of homelessness.

Homeless people face a high rate of chronic health issues, often have complex co-morbidities and can often have conditions left undiagnosed and untreated for long periods of time. This results in an over-reliance on acute health

“Ourfacility.primary cohort are people who are rough sleeping, and we recognise that there are multiple degrees of homelessness,” she said.

24-hour care Residents aged 18 and over can stay for a period of up to 14 days in either service, and admission to the medical respite is by referral. GPs run morning clinics on site every day, while the facility is staffed by nurses overnight and has peer support workers onsite during the day.

Ms Thebaud said residents could take part in painting, cooking and other activities, and had access to computers and phones.

Residents are discharged from the medical beds when their health issues resolve, but if they have other ongoing issues such as trauma, they continued

The centre is operated by a consortium led by Homeless Healthcare with Ruah Community Services and Uniting WA, following a tender process. It is based at a former backpacker hostel once known as the Witch’s Hat, in

“As a GP who has been working in this area since 2014, it’s one thing having GP clinics, but it’s quite another thing seeing people discharged from hospital and then having to send them back because they’ve deteriorated,” Dr Davies “Havingsaid. the ability to bring someone into a recovery-focused environment has been a real gamechanger for stabilising people and getting them out of homelessness.” Dr Davies said the idea for the centre came from a Boston facility which had a very medical focus, with 112 curtained-off beds so it looked like a hospital – and the concept was tweaked from there.

“The thing I really wanted to add to it was the case management side of things, to get people socially stable because I think that’s the single biggest thing that’s impacting their Perth’shealth.”medical respite centre was endorsed by the State Government’s Sustainable Health Review, which highlighted the complexity of issues facing one of the most vulnerable groups in our society.

It also allows support workers to connect people to housing and accommodation and other community supports, and provides a window of opportunity to develop skills for independent living and help people transition out of homelessness.

It is hoped that the facility could significantly reduce rates of hospital admission and readmission in vulnerable rough sleepers.

Dr Davies said homeless people had a reduced life expectancy, with 47 the average age of death. People coming out of hospital often had medical issues such as diabetes, post-surgery complications, infections or a combination of medical problems.

Dr Davies said it was made very clear to everyone that the facility was not a hospital, but it could help prevent hospital admissions and readmissions, or visits to emergency

While Dr Davies welcomes the involvement of more GPs, he said getting doctors on board had been ‘the easy bit’, with the main challenge being not only securing government funding but keeping it in the long-term.

Referrals desirable Ms Thebaud said that just as the facility was not a hospital, it was also not crisis accommodation.

The $30 daily fee for nonmedical beds was useful in motivating people to look for other “Iaccommodation.thinkpeoplevalue it more when there’s a monetary contribution, and we do offer financial counselling to help people work out budgets,” she said. “It’s about people having somewhere to recover when they’ve been discharged from hospital. Without this they’d be going somewhere that’s non-compatible with recovery.”

“Ifdepartments.wecanmanage to get people from the streets into hospital, through here and then out to some kind of more permanent accommodation, then it will have a real long-term impact. It’s not just about this admission or preventing the next one,” Dr Davies said.

Rooms at the front of the house are for those who are unwell and need closer monitoring, while rooms towards the back are for those who are more independent. Security is only used at night, but good safety measures have meant there has been very few incidents, which have been well-managed by staff. As details of the facility have spread among Perth doctors, nurses and other health workers, demand has been increasing.

“We can receive referrals from the community to avert someone from going to hospital in the first place –people who are sleeping rough and would more than likely end up in

It was difficult for people to recover from medical treatment if they were sleeping rough and couch surfing, and some people needed antibiotics that could be stolen from them on the streets.

Anzac House Veteran Central, the reenvisioned service centre for the RSL WA, has produced agile adaptations to service delivery to broaden accessibility.

“They have been so successful that the former government instituted a series of veteran wellness centres (rebadged as ‘veteran hubs’ by Labor) nationally. They're using our model to try and replicate them throughout Australia.

“We have found out as we have rolled out this initiative, which started about five years ago, that it works because it's simple. You put the veteran and their family at the centre of the circle and rather than looking outwards for services, veteran service providers can reach inward – they are actively looking to give complementary services to a veteran.

“The different service providers are private and pay a very reasonable rent at Anzac House on a contract that says that they give absolute priority to veterans. Their income is via the Medicare schedule or the DVA schedule or mixture of both.”

Medical Forum caught up with veteran and retiring CEO John McCourt to discuss the crucial insights gleaned from the Veteran Central

“What we've developed at Veterans Central in Perth is that the veteran can come in – and, indeed, serving members if they feel that they have a need to – and access services.

The hub-and-spoke co-operative model of care that has been enthusiastically adopted by WA Health recently, after the release of the Infant Child and Adolescent Taskforce report in March, has been humming along successfully for five years at Anzac House, providing holistic care for veterans.

There are doctors who will treat them as a GP, all the way through to dental assistance, medical hearing assistance, legal advice, financial advice, welfare support and advocacy advice, all under one roof.

Mr McCourt said that veterans and their families, even with minimal service, are issued with a White Card that entitles them to free mental health care. For injured veterans, the co-location of services enables the referral process to escalate organically from the GP to the specialist, who could attend as a consultant, to surgery at either a private or public hospital, with wait times closely monitored by the team who would advocate on their behalf.“Similarly, if a veteran comes in and says they have mental health issues, there are three tiers of mental health services at Anzac House Veterans Central,” he “Theresaid. is what they call the entry service, Open Arms, which is the Federal Government Mental Health Support Service, we have clinical psychologists, and we also have a Thepsychiatrist.”teamisnow moving beyond physical attendance to make their services available virtually, another key area highlighted for growth in wider healthcare planning, and Mr McCourt said that the value it represented for veterans was “Forundeniable.example, if someone's living in the Pilbara region and they need various supports – they may have mental health needs or physical health needs – they will benefit being triaged virtually,” he said. “And then if and when they must travel to Perth, they can get everything seen to at the same time, rather than up and back and up and Mrback.”McCourt said the team had learned two key factors since the start of the hub – the first of which was to make sure that the environment was as welcoming as “Andpossible.itsounds a bit trite but this building, for example, is open, it's got plenty of large windows and sky and it's not enclosed, it's not intimidating, it's relaxed.

“Asthma deaths are generally declining, but 421 Australians died of asthma in 2019. Even if that’s a smaller number than it used to be, that’s still 421 too many deaths. We would like it to be as close to zero as possible,” he told Medical Forum

While there is a long-term declining trend in asthma-related deaths, the 417 deaths due to asthma in 2020 isn’t a significant fall from the previous year.

A Medical Journal of Australia study published in 2015 showed that many Australians with asthma were missing out on effective treatments that could improve their asthma Itcontrol.found that only about half of people with asthma had good control and about a quarter had very poor control over their condition. In people with uncontrolled asthma, quite a large proportion were not using regular preventer medicines.

“Using this combination inhaler simply as needed may seem unusual at first because many of us would have been taught at medical school that steroids have to be taken regularly to work. I know I was sceptical initially. But there are now several big trials that looked at that strategy and found it is safe and about as effective as the traditional regular ICS plus as-needed SABA approach. That’s why they’re both seen as legitimate options now,” he said. Dr Montgomery likes to remind his patients about how ICS and SABA medicines differ.

Standard care Dr Montgomery said that most patients should be on a low dose of an inhaled corticosteroid medicine to improve lung function and to reduce the risk of and to prevent otherwise preventable exacerbations of asthma and Ifhospitalisations.thistreatment was not working effectively after several weeks – and assuming the patient was taking it correctly – then a longacting beta-agonist (LABA) lasting 12 or more hours could be incorporated into the treatment in combination with the low-dose

It has been standard practice for many years in Australia for doctors to prescribe regular daily maintenance of inhaled corticosteroid (ICS) at a low dose plus a SABA reliever as needed.

Dr Montgomery adds that patients should know that persistent symptoms of feeling wheezy or tight in the morning or overnight, frequent reliever use, or asthma interfering in their lives are all indications they are at higher risk of having a significant exacerbation of asthma which could be detrimental enough to land them in hospital or even cause death.

“If ICS medicines aren’t felt to work as quickly as they expect, some people give up on them and they just stick to what gives them instant relief. That’s a shame, because they’re missing out on significant protection. One thing I try to do with patients is to set them up with the right expectations for their new medicine, so they give it a good go for a few weeks rather than rushing to judgment.”

“The idea of that is you use it regularly, so you’re taking it twice a day, but on top of that you’re taking another puff from the same inhaler as you need it if you get symptoms,” Dr Montgomery explains. “This is a regime for people who haven’t got good asthma control on simpler preventers like a low-dose ICS Whatalone.”is much newer, though, is the use in mild asthma of budesonideformoterol in mild asthma simply as-needed, without a regular maintenance component.

“This isn’t how things should be if we were following the evidence,” Dr Montgomery said. “What we should be seeing is most people using lower doses of steroids, and most of those people using them frequently.

National Asthma Council Australia’s updated Asthma Handbook outlines optimal ways to manage the treatment of the condition at different stages, from mild to severe asthma, with the guidelines clearly stating that taking a simple shortacting beta-agonist (SABA) reliever medication alone is not enough. “There are very few people who have mild enough asthma that we’d be comfortable for them to use just the reliever puffers they can get over the counter,” Dr Montgomery said. “Almost all adults and adolescents with asthma should be on more than just a SABA.”

A study published in 2020, which looked at a sample of PBS data from 2014 to 2018, suggests that more than two-thirds of people being prescribed corticosteroids were being prescribed higher doses and most of those people were using them infrequently.

Today, like every other day, someone in Australia will have an accident and join over 20,000 people in the country who live with the devastating consequences of a spinal cord injury (SCI). And lying paralysed in hospital, they will probably be told they will never walk again. This was true 38 years ago when a drunk driver left me at the side of the road, paralysed from the shoulders down. However, recent research breakthroughs have brought us to a time when those newly injured should not be given such dreadful and finite news. A spinal cord injury is a lot more than losing ability to walk. Severing communication between the brain and body affects every aspect of your physical and mental wellbeing. Loss of movement is just the tip of the iceberg – ongoing pain, digestive issues, pressure sores, spasms, loss of bladder and bowel control and impaired sexual function are just some of the effects that make everyday life so Indifficult.addition to this dreadful human cost, SCI is estimated to cost the Australian economy $3.7 billion a year with a lifetime cost burden (2020) of $75.4 billion, with $10.3b of this borne by WA. Apart from the support of loved ones and friends, and the innate capacity of people to handle adversity, there is another factor that feeds the ability to cope with all this – hope. For those of us who live with paralysis, that hope comes from scientific research and the progress towards a cure. An incredible milestone in SCI research was reached in 2018. Six volunteers recovered the ability to stand and walk with only the aid of a walking frame, years after they were injured. These exceptional results were achieved by an experimental treatment known as Mostneurostimulation.spinalcordinjuries in Australia are contusion injuries, where the spinal cord is crushed on one side but not completely severed.

Most of the headline results have been achieved by electrical stimulators implanted in the epidural space, but this requires an expensive operation, weeks of hospitalisation and is not without risks. The alternative is to place electrodes on the skin (termed transcutaneous neurostimulation), which is safe, inexpensive and can be made more widely available.

Hope for spinal injury becomes reality don't provide sufficient scientific evidence for the authorities to approve a stimulator for mainstream use.

The Find Cancer Early program aims to improve cancer outcomes for regional West Australians over the age of 40 by increasing cancer symptom awareness and encouraging people to visit their doctor, clinic nurse, or Aboriginal health worker earlier. recent campaign evaluation found that 70 per cent of 953 regional West Australians surveyed had seen the campaign, and as a result of seeing the campaign 108 people made an appointment with a General Practitioner (GP), while 245 people thought about making an appointment. In Australia, over 75 per cent of cancer cases first present in general practice as a result of symptoms. GPs play a vital role in the early detection of cancer, and regional GP’s especially have the potential to improve cancer survival rates for regional West Australians and close the gap. Our Find Cancer Early Guide for GPs assists GPs in the early diagnosis of prostate, lung, colorectal, breast and skin cancers. This guide employs evidence-based positive predictive value (PPV) tables that highlight the clinical features that best predict cancer. We recommend regional GPs download or print off our Find Cancer Early Guide for GPs at findcancerearly.com.au/gp/ and get into the habit of referring to it for guidance when patients report symptoms.

Cardiac exercise stress testing offers a non-invasive approach for those with suspected coronary Australian Council of Trade Unions, we used a unique method which predicts how many Australian workers would develop lung cancer and silicosis in their lifetime as a result of their exposure to silica dust in one year. To do this, we started with an estimate of how many workers were exposed to silica dust in 2016, the most recent census data year available. We used past exposure surveys and reports from New South Wales and Victoria, as well as data from the census around the number of engineered stone workers in Australia. We estimated that 584,000 Australians are exposed to silica dust at work. We then modelled how many lung-cancer and silicosis cases would develop as a result of this exposure and looked at the impact of ways to reduce that exposure, including wet cutting, using good quality respirators, and banning engineered stone. artery disease. However, up to onethird of exercise stress test results are either inconclusive or nondiagnostic, resulting in significant resource wastage.

While silicosis has historically been rare in Australia, the increased UWA chair of Cardiology, Fiona Stanley Hospital-based Perkins researcher and scientific officer of medtech company Artrya Professor Girish Dwivedi has been exploring the potential of AI in a busy metropolitan emergency department.

Silica dust is an aggressive lungdamaging dust which can result in breathing difficulties, scarring of the lungs (silicosis) and lung cancer. We have estimated that as many as 10,000 Australian workers will develop lung cancer in their lifetime as a result of their exposure to silica dust, and 103,000 will be diagnosed with silicosis.

About 7% of Australian workers, or more than half a million people, are currently exposed to silica dust across various jobs, with exposure most common among miners and construction workers.

As a result, Safe Work Australia has recently released a regulatory impact statement for consultation. This statement looks at a number of options to reduce exposure to silica dust and the cost of these over the next 10 years.

The AI system, developed by the multidisciplinary research team using demographic and pre-test clinical information, can accurately predict exercise stress test results and could be used to identify patients who would have inconclusive or nondiagnostic results.

Silica dust is found naturally in many building and construction products, including sand, stone, concrete and mortar. It is also used in the manufacture of building products such as bricks, tiles and glass. Engineered stone, used mainly for kitchen benchtops, is a particularly potent source of silica dust.

“There is growing recognition that there is significant variation in investigation practices, with associated patient harm, healthcare waste and economic cost.”

There are multiple investigation modalities available, each with their unique strengths and weaknesses. The decision on which investigation is most appropriate for the patient has become increasingly complex,” Prof Dwivedi said.

Dr Renee Carey says much more can be done to prevent a predicted rush of silicosis and lung cancer cases across Australia.

Banning silica dust in other industries such as mining and construction isn’t feasible. However, it is possible to reduce exposure and the resulting health effects.

A simple questionnaire has been developed to detect SHS, which has been validated among African Asian and Caucasian populations as a generic tool for health measure. People presenting with SHS tend to have varying health complaints accompanied by anxiety or depression and fatigue, and the sum of these conditions can have effects on mental health and the cardiovascular, digestive, and immune systems. Risk factors are broadly considered to be related to environmental and lifestyle factors and include smoking, work stress, air and noise pollution, lack of exercise, and poor dietary choices. Understanding SHS is important when one considers the proven links between SHS and chronic diseases such as cardiovascular disease and diabetes.

Researchers have demonstrated that tourism can improve a person’s wellbeing, which is a complex state that, in a broad sense, describes a person’s quality of life. Tourism experiences promote positive psychology, optimism, relaxation, and personal growth. Physical activity and leisure experiences tend to happen simultaneously with tourism, and both exercise and leisure experiences are powerful tools to promote wellness.

The multidisciplinary team from the SHSC analysed questionnaire responses from 360 Chinese tourists and looked for correlations between SHS and tourism-related characteristics. Overall prevalence of SHS was 36.4%. Study participants who reported longer sleep at night and more physical activity had lower prevalence of PeopleSHS. with SHS who travelled frequently reported better mental health than those who did not travel often. The tourists who traveled more frequently also had a better immune status, not all that surprising given the known positive correlation between physical activity and the immune system.

When we consider the economic and emotional toll that poor health takes on society, it is exciting to imagine how the research happening at the SHSC will inspire others to expand the way they approach this and other topics of global significance.

Motivated by the widespread prevalence of SHS and the implications of not addressing it, Prof Wang recently enlisted the expertise of a multidisciplinary team to explore a unique way to address the SHS concern: tourism. This is in fact the first study to introduce SHS to the field of tourism, and tourism to the field of global health focusing on SHS.

At time of writing, New Zealand is still where WA was at in April and the rest of Australia in February. You walk into a restaurant with mask on but take it off when you sit down. Case numbers in NZ are following the same trajectory as Australia as we followed the international pattern –just a bit later.

In 1970 Joni Mitchell sang “Don’t it always seem to go, that you don’t know what you got till it’s gone”. In 2022 this could apply to the state of general practice. The new federal minister has noticed that there is a crisis and direct billing is under threat. Absolute numbers can’t be obtained but the workforce is thought to have shrunk by 3-5% through COVID.

For many it feels like we have been hibernating for over two years. This column is written in New Zealand as we visit relatives not seen in three years.

Nodule assessment on non-lung CTs has limitations. Confirmation with a dedicated CT chest is Nodulefavourable.risk assessment for lung cancer depends on several factors. Clinical factors include age, family history of lung cancer and other cancers, asbestos exposure, and cigarette smoking. Absence of a smoking history does not exclude lung cancer.

Radiological characteristics such as size, shape, spiculation, effect on adjacent pulmonary architecture and background emphysema need to be interpreted. Peri-fissural nodules represent intrapulmonary lymph nodes and are usually benign although there are exceptions. Presence of mediastinal or hilar lymphadenopathy indicates urgent assessment irrespective of the nodule size.

Lung nodules are best evaluated on thin (</=1mm) slice CT reconstruction. There are limitations in comparing two scans with different slice thickness, a dedicated CT chest versus a nonlung CT and even CT chests done on different machines. Comparison with previous CT imaging is an important initial step during nodule assessment. Availability of prior imaging at the time of reporting adds value for the reporting radiologist and the clinician.

Nodule malignancy risk stratification

By Dr Lokesh Yagnik, Interventional Pulmonologist, Subiaco 41

A pulmonary nodule is a welldefined opacity surrounded by lung parenchyma measuring less than 3cm (greater than 3cm is a lung mass). Pulmonary nodules are classified as solid or subsolid. Subsolid nodules are subclassified into pure ground glass and part solid nodules.

Identifying the clinical context at the time of CT chest scan is paramount. If there are features of infection, then an inflammatory nodule is likely and may resolve at short term interval follow up CT. Alternatively, if detected on a screening CT chest, the malignancy risk is higher. There are several risk assessment scores used to determine the malignancy risk of a lung nodule.

A persistent nodule is concerning and an enlarging nodule highly suspicious for malignancy. If a nodule is persistent but stable in size and shape, radiological surveillance with CT scans for 24 months for solid nodules and up to five years for ground glass/ part solid nodules is a reasonable approach. Alternatively, evaluation with a FDG PET and proceeding to a biopsy is acceptable. For a nodule deemed low risk, surveillance is favoured. Managing patient anxiety around the detection of a lung nodule and consideration of their preferences during assessment is helpful in achieving good outcomes. Work up also includes lung function testing and assessing fitness for surgery since treatment options for earlystage lung cancer are lobar or sublobar surgical resection or for nonsurgical candidates, stereotactic body radiation therapy. This is often recommended following an MDT discussion.

Children with neurological disorders are more likely to need hospitalisation with pneumonia Prevention and treating modifiable risk factors are key New research seeks to identify ways to reduce symptoms and hospitalisations.

By Dr Rachael Marpole, Adv. Trainee, Respiratory & Sleep Medicine, PCH on Page 43

• Prevention by treating/managing modifiable risk factors is key.

We have identified three key risk factors for admission for acute respiratory infections in children with cerebral palsy (see Fig. 1). These include severe cerebral palsy (inability to control head posture against gravity), admission to hospital during the previous year, or two courses of oral antibiotics in the previous year. We have also worked on identifying potentially modifiable risk factors including oropharyngeal dysphagia (mealtime modifications like tube feeding, thickened fluids), frequent respiratory symptoms (coughing, choking on saliva, wheezing, or gurgling), current seizures, gastrooesophageal reflux, mealtime respiratory symptoms, nightly snoring and poor dental hygiene. What does it mean for GPs?

continued from Page 39

Pneumonia, a common cause for acute respiratory infection, is one of the most common causes of hospital admissions in children. We know that children with neurological disorders (e.g. cerebral palsy, epilepsy, and neuromuscular disorders) are more likely to be admitted to hospital with pneumonia than children with other conditions but, until recently, little was known why. We also know these children are older, have a longer length of stay and are more likely to be admitted to intensive care. When these children are tested, a respiratory pathogen is less likely to be found, because the cause of their pneumonia is from aspiration and not from infection.

• Maximise general health including ensuring current vaccination protection, dental hygiene, nutritional status, and physical activity is optimised.

For intermediate risk nodules, the options depend on the clinical circumstance, patient preference and risks of diagnostic biopsy.

CLINICAL UPDATE

bronchoscopy is recommended for all lung nodules proven or suspicious for lung cancer when they are within the inner two thirds of the lung fields, associated with abnormal thoracic lymph nodes on CT chest or PET and when the lung nodule is not PET avid. Adenocarcinomas and intensely FDG avid lung cancers also carry a higher risk of occult nodal metastasis and tissue confirmation of nodal status is advantageous. Biopsy of the peripheral lung nodule can be performed at the same bronchoscopy by using a radial EBUS probe if the lymph nodes are non-malignant at onsite examination (Image A). EBUS bronchoscopy has an excellent safety profile. Alternatively, the nodule can be biopsied by CT guidance as a separate procedure.

When there is a history of infective symptoms at presentation when initial CT was done, then a shortterm interval CT scan can be done in six weeks to three months with antibiotic treatment assessing for temporal behaviour. Inflammatory nodules usually reduce in size or resolve on follow-up scan.

The demonstration of irreversible airflow limitation on spirometry (post bronchodilator FEV1/FVC ratio <0.7) in the presence of a history of cigarette smoking (more than 10 pack years) or other contributors such as air pollution makes a diagnosis of COPD likely. The degree of airflow limitation, however, is not a reliable predictor of symptom severity in COPD.

As with the assessment of any respiratory disease, smoking cessation is imperative as it is the only intervention with clear positive impact on disease progression.

Mostly bronchodilator therapy does not lead to a sudden increase in lung function or reduction in symptoms but many of the benefits (quality of life) are over longer term.

Initial COPD management includes a combination of pharmacological and nonpharmacological strategies. Patient education of COPD is vital, so people understand what they have and what treatment is for. Up-to-date vaccinations for flu, pneumococcus and COVID can help reduce exacerbation frequency and severity. Exercise helps maintain fitness and weight control. This can be incorporated into a pulmonary rehabilitation program although there are several administrative barriers to this (referral usually needs to be from a specialist or Pharmacologicalhospital).therapy can improve symptoms, quality of life, and reduce exacerbation risk but there’s no reliable evidence of a positive impact on disease progression or overall mortality. Therapy needs to be targeted to the symptoms to be treated. Generally, all patients will complain of breathlessness so generally all patients will benefit from bronchodilator therapy. Local guidelines (copdx.org.au) detail the initiation of bronchodilator therapy but generally for someone who is symptomatic most of the time either a regular long-acting beta agonist (LABA) or longacting muscarinic antagonist (LAMA) is indicated. If symptoms persist, adding the alternative bronchodilators so they’re on dual therapy (LABA/LAMA) is indicated.

Initial diagnosis and assessment of COPD

Author competing interest – nil

COPD is a common lung disease responsible for significant disability. It is a common cause of hospitalisation and death. In Australia it is under diagnosed and often over or even undertreated. Primarily a lung disease, it has extrapulmonary manifestations and is frequently associated with respiratory and non-respiratory comorbidities all of which can influence symptoms and outcomes. Spirometry is the essential test in diagnosing COPD. There is no other way of demonstrating airflow limitation and so confirming COPD. Barriers to performing spirometry are rarely insurmountable, even with the current COVID pandemic.

By Dr Scott Claxton, Respiratory Physician, JoondalupCONTENTSTOBACK

In initial managementpharmacologicalofCOPD,there is little role for inhaled corticosteroids (ICS). They have a role to play in the patient with frequent exacerbations despite dual bronchodilator therapy but at a lower dose than usually used for asthma. Long-term ICS use still has the risk of long-term steroid side effects (e.g. cataracts, bone density, infection). Given the significant co-morbidities for COPD patients, the risk and benefits of ICS therapy needs to be assessed. Diagnosing COPD with the appropriate smoking history can be straightforward but a proportion of patients will have asthma-COPD overlap and this may require more specialist investigation to confirm the diagnosis and ensure appropriate therapy. This may be considered if there is prior history of asthma and a history of significant smoking or if there are asthma features at presentation (variable symptoms, bronchodilator response on spirometry).

Further assessment for defining the severity of COPD depends on measuring the severity of symptoms. This includes exercise tolerance (modified Medical Research Council [mMRC] scale), general COPD symptoms (COPD Assessment Test score [www. catestonline.org]) and exacerbation frequency (≥ two exacerbations or ≥ 1 Thissevere).allows a consideration of potential symptoms of exertional dyspnoea, cough, general fatigue, exacerbation risk with a view to directing therapy. Appropriate choice of pharmacological therapy lowers likelihood of overtreatment or unnecessary treatment. Chest radiology is helpful insofar as identifying comorbid respiratory conditions (e.g. emphysema, fibrosis, lung nodules or bronchiectasis). It is not sufficient to make the diagnosis alone. Other investigations can be helpful in assessing extra pulmonary disease (e.g. cardiovascular disease, osteoporosis, type two diabetes, hypertension). These can be done depending on the clinical picture and likelihood of the presence of other diseases.

Tailored therapy can provide optimal outcomes while avoiding undertreatment and poor disease control or overtreatment with potentially significant side effects.

increases the likelihood

Although a stronger positive sIgE result increases the likelihood of the patient having a clinically significant allergy, it does not reliably correlate with severity of the allergy; assessment of severity, and thus indication for carriage of adrenaline autoinjectors, is based on the clinical Whenhistory.a patient tests positive to an allergen via standard sIgE testing, it is not possible to know which of the many antigens contained within the ‘cap’ the patient has IgE antibodies directed towards. It is helpful to appreciate this concept, as not all antigens have equal clinical significance. In fact, patients with significant allergies to certain exposures may be reliably sensitised to only a few specific antigens of interest. Furthermore, some antigens show substantial cross-reactivity with other allergens, a common cause of ‘false positive’ results. For example, grass pollens contain proteins also common to many plant-based foods, causing some pollen allergic patients to also show positive sIgE results to certain foods. Many of these cross-reactive proteins are labile, meaning they do not survive cooking or digestion, thus not precipitating systemic allergic reactions when ingested. Therefore, although the food sIgE result is positive, the patient is not clinically Recognitionallergic. of this phenomenon has led to development of ‘component resolved diagnostics’, where sIgE testing is directed towards individual allergen components. For example, most patients with peanut anaphylaxis will be sensitised to the peanut protein Ara h 2. Thus, testing for sIgE towards Ara h 2 specifically can aid in determining whether a patient with positive peanut sIgE is more or less likely to tolerate a peanut challenge or be at ongoing risk of Investigationanaphylaxis.ofvenom allergy is another example where component resolved diagnostics can assist management. Bee and wasp venoms contain several cross-reactive components, most notably crossreactive carbohydrate determinants (CCDs). Therefore, some patients have positive sIgE tests towards both bee and wasp venom despite being clinically allergic to only one species. In this situation, sIgE testing towards species specific proteins – e.g. Api m 1 for bee venom – can determine the primary allergy and thus ensure prescription of appropriate desensitisation

Accurate diagnosis of allergy requires careful clinical assessment and demonstration of allergen sensitisation, defined as presence of IgE antibodies targeting allergen components (antigens). The main methods used to establish sensitisation are skin prick testing (SPT) and serological testing. SPT is generally only performed by specialist allergists/ immunologists, but serological testing can be requested by all clinicians.

Historically, the radioallergoabsorbent test (RAST) was the predominant serological method. This has now been superseded by a similar method known as serum specific IgE (sIgE) testing.

Ininterchangeably.sIgEtesting,patient serum is incubated in a small ‘cap’ containing antigens representative of the allergen in question, typically derived from whole allergen extracts. IgE antibodies targeting any of these antigens will be bound. The amount of IgE binding is then determined and reported quantitatively. Sensitisation can occur in the absence of a clinical syndrome of allergy, so sIgE results must be interpreted in the clinical context.

Handheld CLE devices enable in vivo digital visualisation of tissue histoarchitecture with absolute recapitulation of standard histomicroscopy allowing real-time assessment of pathological tissues and clearance of resection margins, with on-the-fly communication between surgeon and pathologist.

Accurate decision-making during surgical resection of various human cancers is reliant on good communication between surgeon and pathologist. The frozen section is essentially unchanged since described by pathologist Dr Louis B. Wilson in 1905 at the request of surgeon Dr William Mayo, one of the founders of the Mayo Clinic.

Real-time intraoperative digital pathology for surgical oncology

Figure 2 Figure 1

Despite the historic value of the frozen section, many surgeons and pathologists alike question its utility, arguing that assessing the ex vivo resection or the surgical bed is of greater clinical benefit. Various studies support these varying approaches in distinct cancer types including head and neck, breast and brain.

In the recently published study, neurosurgeons used CLE to treat six patients with gliomas, three with other primary brain tumours, one with metastasis, and one with reactive brain tissue. Video-flow images were generated of the operative field during surgery, while pathologists viewed the images simultaneously outside the operating theatre at distant sites. One was in another state, four were at home, and six were elsewhere in the hospital. All video and still CLE images were correlated to corresponding frozen section and standard H&E histology sections. Video-flow CLE allowed correct tissue histoarchitecture interpretation in 96% of digital biopsies. This was possible in a fraction of the time taken to undertaken frozen section assessment. The duration of application of the CLE system was one minute per case and 0.25 seconds per digital biopsy, with the first image that demonstrated identifiable histopathological features being acquired within six seconds. Frozen sections were processed within 23 minutes, which was statistically significantly longer than CLE Intraoperativeimaging.digital pathology with CLE allowed real-time assessment of tissue histoarchitecture without taking tissue biopsies, facilitated communication between surgeon and pathologist, and permitted accurate decision-making during oncological surgery. Overall, it resulted in immediate informed decisions with significant advantages over frozen section Anassessment.example of this approach in the context of head and neck pathology is provided here, where a moderately dysplastic oral epithelial lesion is imaged before resection (Fig. 1), after which the peripheral mucosal (Fig. 2) and deep surgical (Figs. 3-5) margins were imaged.

As the average age of mothers in Australia increases, more women who are over 40 years and breastfeeding are contacting BreastScreen WA for a screening mammogram. Screening mammograms are significantly less effective in detecting breast cancers during breastfeeding due to increased breast density. Women who are breastfeeding are advised to postpone their screening mammogram until 3 months after cessation of lactation. This allows the breast tissue to return to pre-breastfeeding density.

Maximal growth of IHs occurs in the first eight weeks of life. A small IH in the first two weeks can grow quickly, so early referral is essential.

IHs that ulcerate will leave scarring.

understand beta blockers do not cause the hemangioma to shrink away immediately, rather the aim is to stop the IH from growing any bigger. Beta blockers are continued until the time the IH would have naturally stopped growing, and then the IH can continue to naturally involute. This process can take two to seven years and occasionally longer.

An international panel of more than 220 medical experts and experts with lived experience, representing over 100 countries, have been active since 2020 in co-designing the model and operational framework for the GNRD. The pilot will connect multi-disciplined centres of expertise to collaborate globally, providing the bedrock of a structured, inclusive approach for all regions and all rare diseases, to help ensure no one is left behind.

Segmental port wine stains (PWS) of the face involving the forehead or upper eyelids can be associated with Sturge Weber syndrome requiring MRI, ophthalmology review and close monitoring for any signs of seizure activity or developmental delay, with paediatric neurology. Multiple PWS on the body should be referred for review.

In these cases, longitudinal monitoring is Therequired.infantile hemangioma with minimal or arrested growth (IHMAG) can mimic a reticulate PWS. The clue in the latter condition is tiny dark blebs that appear over time.

The complexity of rare diseases and their infrequency have forced an evolution in the model of care from a multi-disciplinary approach towards ‘networked care’, to enable access to expertise from across an international network of experts to inform local care. The establishment of the GNRD will connect rare disease centres of expertise with progressively expanding geographical and disease coverage and be transformative to help dissolve the existing barriers for a large and vulnerable population.

A simple venous or lymphatic malformation usually presents as a bluish or skin coloured swelling. Venous malformations tend to be compressible. Treatment may be sought if cosmetically bothersome and or causing pain. A combination of physical therapy (compression), surgery, sclerotherapy, and emerging medical therapies (oral sirolimus and anticoagulation) can be trialled to improve cosmesis, pain and function. Those with multiple blue swellings should be referred for assessment.

Now is the time to translate political willingness into action by supporting the creation of networks of experts and multidisciplinary and cross-sector specialised centres for rare disease. This will lay the foundation for the development of a Global Network for RD (GNRD).

Salmon patches Salmon patches (simplex nevus) also known as stork marks or angel kisses, are common, superficial capillary vascular malformations that can affect the upper lip, nose, glabella, eyelids, forehead, scalp, occiput, and lower back. The eyelid and faint glabella salmon patches (SPs) will routinely fade, but paranasal, lip, prominent V shaped on the forehead, scalp, occiput, and lower back SPs tend to persist. Those persistent at 12 months are unlikely to fade. Pulse dye laser is offered for SPs unlikely to self-resolve as soon as possible; laser is better tolerated in younger children, and often less treatments are required.

The first hybrid surgical and catheter AF ablation program (HyCASA = Hybrid catheter and surgical ablation) of its kind in the Southern Hemisphere has been established in Perth and is now a global education centre for this procedure. Since catheter ablation of AF was first described in 1998, the use of this intervention has increased exponentially, and its annual growth rate exceeds other cardiac interventions. This increased use of catheter ablation in AF management is supported by randomised controlled trials and clinical guidelines and has also been driven by major technological advances.

Atrial fibrillation (AF) is the most common sustained rhythm disorder, and its treatment has been revolutionised during the past 20 years. This includes improved detection (Apple watch etc), better anticoagulation (DOAC), left atrial appendage management and catheter ablation.

An endocardial catheter-only approach to posterior LA wall ablation is challenging due to risk of thermal injury to the oesophagus, which potentially leads to the extremely rare but devastating complication of atrial-oesophageal fistula (estimated 80% mortality).

HyCASA ablation strategy This comprises epicardial surgical and endocardial ablation components. The ablation target is the posterior left atrial wall between the four pulmonary veins. This area is targeted in patients with non-pulmonary vein mediated AF because a high percentage of non-PV sources originate from this anatomical region which shares the same embryologic origin (and therefore electrophysiology) as the pulmonary veins.

Technological advances have greatly improved our accuracy of energy titration during catheter ablation. This avoids excessive energy delivery reducing the risk of tamponade, phrenic nerve palsy and oesophageal injury and also avoids inadequate Epicardial thoracoscopic posterior wall ablation

The health inequities faced by people living with a rare disease are further amplified in regional and remote regions and indigenous populations.

There has been increasing incidence of AF in all industrialised populations with an increase of 1.2% per annum seen in Western Australia between 1995 and 2010. Catheter ablation alone is highly effective in patients with a small left atrium and paroxysmal AF, though challenges remain for those patients with a large left atrium and persistent AF.

Many recent advances have occurred because practical application of high-performance computing in the catheterisation laboratory allows rapid computation of location, cardiac signals, and catheter contact ‘on the fly’.

Of particular note was the contribution of legendary winemaker the late Jack Mann, who did a staggering 51 vintages at Houghton Wines. In 1937, he created the Houghton White Burgundy, a Chenin Blanc-based wine, which has been one of the biggest selling wines in Australia and still enjoys good sales (since 2005 as Houghton Classic White to comply with EU labelling laws).

My pick of the tasting. This wine has vibrant lifted aromatics showing stone fruit, tropical pineapple characters, and cashew nuts. What I like about this wine is the fruit intensity on the palate, and the balance of fruit, acid and oak. Shows nectarine flavours, mealy characters from lees contact and nutty oak nuances. A very enjoyable value-for-money wine, drinking nicely now, but with qualities which will give it a further five years’ life.

From a good vintage in Frankland. An elegant style with underlying fruit power. The nose is intense, with violets, blackberry and vanillin oak. Flavours of redcurrant, mulberry and some dark chocolate. Very fine grained tannins, drying at this youthful stage. Firm acidity, great structure. Oak is dominant but will integrate. A nice Cabernet with a 10-12-year future.

Attractive in the glass, limpid with a green-gold hue. The nose resplendent, typifying this Margaret River blend, with overt fresh cut grass, dried herbs and green pea. The palate clean and crisp with zingy acid giving structural integrity and a long refreshing finish. Flavours of lime, grapefruit and green capsicum. A lean style with lowish alcohol of 12.5% suggests early picked fruit. Best consumed now but will drink well for a couple of years more.

Houghton 2019 Frankland River Cabernet Sauvignon (rrp $30)

A solid, full bodied, mouth-filling wine. As I have said in my past articles, Shiraz from the Lower Great Southern subregion of Frankland River seldom disappoints, this wine being no exception. Deep red colour with a purple meniscus indicative of this wine’s youthfulness. Aromas of black olive, ripe cherry, with a touch of white pepper. Palate shows satsuma plum, ripe mulberry, plus that varietal spice and pepper. Mellow and integrated. Supple finish. A young wine that will reward over the next 8-10 years.
