Image guided injections – what goes where for which condition?

29th November 2021, Spectrum Medical Imaging

image guided injections

If you are like me, you will be confused as which joints or joint can be injected for which clinical condition. Then you need to know whether they are ultrasound guided procedures or CT scan guided procedures. There just a myriad of musculoskeletal conditions that can improve with corticosteroid injections. Spectrum Medical Imaging has assembled a team of subspecialist interventional and musculoskeletal expert radiologists to assist us in managing our patients with these conditions.…

PRP injections for knee OA – do they work?

29th November 2021, Dr Chee L Khoo

Knee osteoarthritis

If you are over 50 years old, there is no Medicare rebate for an MRI of the knee. They won’t do a “clean out” arthroscopy for symptom relief even if you have significant pain requiring opioids because the symptom relief is only temporary and you will end up needing a total knee replacement anyway.…

Micro-AF – harbinger of AF?

29th November 2021, Dr Chee L Khoo

One of our biggest fears is missing an atrial fibrillation (AF) and patient is discharged from hospital following their first embolic stroke. Almost all the automatic sphygmomanometers do not check for cardiac rhythm and I make it a point to put a finger on the pulse each time to make sure patients are in sinus rhythm.…

PCSK9 inhibitors on the PBS – another kid on the block

13th November 2021, Dr Chee L Khoo

PBS Authority for PCSK9 inhibitors

The authority to prescribe a PCSK9 inhibitors for patients with resistant hyperlipidaemia under the PBS continues to be pretty complicated. We tried to simplified those numerous criteria back in December 2020 here when the criteria were “loosened” somewhat. This has facilitated my prescription of this important drug in those patients who have really, really high cardiovascular risk.…

Pfizer vaccines for children – is it safe and effective?

13th November 2021, Dr Chee L Khoo

5-11 year old

The TGA is examining data from Pfizer on the BNT162b2 vaccination in children between 5-11 years old as I write this article. The US FDA have already approved the vaccine for use in children of those age groups and the US CDC has recommended that children 5-11 years receive the vaccine.…

3rd dose for the non-immunocompromised – is it necessary?

13th November 2021, Dr Chee L Khoo

booster shots?

The success of mass vaccination is demonstrated by the dramatic reduction in case numbers and deaths from Covid-19 infections since the introduction of the covid-19 vaccines worldwide. Countries such as UK, USA, Israel and Singapore started and completed their campaign very early in 2021. Their success has been challenged by the increasing breakthrough in those countries since June 2021.…

The skinny T2D – what do we have to watch out for?

29th October 2021, Dr Chee L Khoo

Which T2D?

Traditionally, we think of diabetes as either type 1 or type 2. That’s mainly because type 1 diabetes (T1D) was discovered first and type 2 diabetes (T2D) came later. Everything that was not T1D was T2D. T1D is an auto immune disease characterised by the death of the beta cells leading to insulin deficiency while T2D is a disease of both insulin resistance and insulin deficiency.…

Spectrum is now at Sydney South West Private Hospital

Sydney Southwest Private Hospital

One of the very few beneficial things over the lockdown period is the easier availability of radiological services. Most radiological practices have reported reduction in throughput during the recent outbreaks. As we emerge from the lockdown, referrals for medical imaging are increasing and with the increase, an increasing wait time for services is happening.…

Dyslipidaemia in the young – who should we suspect?

24th October 2021, Dr Chee L Khoo

Last fortnight we explored the disease burden in patients who have high lipids from a very young age and the effect on their future cardiovascular risk. This consideration allows us to think about who should be aggressively treated and whom we can just safely watch, at least for a few years. It would be nice to be able identify who we should screen for high lipids from a young age so that we can start lifestyle measures early.…

Covid-19 vaccine booster for the immunocompromised – who is eligible?

Booster jab, anyone?

10th October 2021, Dr Chee L Khoo

Updated 17th October 2021

You would have caught a bit of the announcement that some people may be due a Covid-19 vaccine booster. As usual, the announcement is not precise or detailed enough and now everyone is confused whether they are the intended target group for the booster. It is not a call to boosters for most vaccinated people.…

Oral anti-viral against Covid-19 – how does it work?

5th October 2021, Dr Chee L Khoo

The media is abuzz with this wonder oral drug for treatment of Covid-19 infection by Merck, Sharp & Dohme (MSD). We are talking about Molnupiravir, the broad spectrum anti-viral agent which inhibits replication of not just Covid-19 but many other viruses in cell culture. What is Molnupiravir? Who amongst the patients with Covid-19 infections will benefit from the drug?…

Dyslipidaemia in young adults – should we be treating?

2nd October 2021, Dr Chee L Khoo

cumulative high lipids

We generally see two categories of patients with high lipids, one who had normal lipids earlier on in life but developed high lipids later in life because of modern living and one whose lipids were already high when they were young (and slim and fit). Most of the scientific studies linking high lipids with cardiovascular (CV) events look at lipid levels at a snap point in time, at enrolment and the follow up period just aren’t long enough.…
