Does wearing a facemask cause hypoxia?

14th November 2020, Dr Chee L Khoo

facemasks

It’s been at least 12 weeks since we started to wear facemasks at the practice full time with all face to face consultations. I must admit that during the first week, I did feel a bit suffocating with the mask on. I remember having to stop mid-sentence to catch my breath. I could sympathise with many patients, particularly patients who has COPD, asthma or heart failure.…

Maximising iron supplement absorption – what works and what doesn’t

14th November 2020, Dr Chee L Khoo

Iron supplements

We all know how difficult it is to treat iron deficiency anaemia (IDA) with oral iron supplements. Oral iron supplements not only cause constipation in many patients but they take forever to reverse the iron deficiency anaemia. Gastrointestinal absorption is a problem no matter how many iron tablets you take a day.…

Multi-use lancet device for blood glucose monitoring – URGENT cautionary tale

27th October 2020, Dr Chee L Khoo

blood glucose monitoring

Some of you would have read about the use of the multi-use lancet devices for testing different individuals that was in mandatory quarantine in Victoria between March and August this year. The lancets were disposable but the device holding the lancets were not. I thought everyone knew. I was wrong. Judging by the comments online after the publication of that issue in the Medical Republic, I suspect many of you don’t actually know the infection risk these devices pose and I felt the imperative to write this urgent article.…

Covid-19 and newborn – scary stuff?

25th October 2020, Dr Chee L Khoo

Covid-19 and newborn

Although our numbers of new Covid-19 infections and community transmission is pretty good in comparison with most other countries in the world, it isn’t zero. This is as good as it gets for at least the next 12 months. One of the scariest things is transmission of the virus to the newborn if the pregnant mother has the Covid-19 infection.…

Aortic aneurysm and fluoroquinolones don’t mix well – do they?

13th October 2020, Dr Chee L Khoo

Aortic aneurysm (AA) and aortic dissection (AD) are potentially fatal conditions. Without treatment, ruptured AA/AD carries a mortality rate of up to 90%. Population-based studies estimated the annual incidence to be 2.4 to 14.8 per 100 000 persons for AA (1-4) and 3.8 to 8.8 per 100 000 persons for AD (3,5-7). Although the incidence varied across countries, the number has universally increased over time (1-5,7).…

Can lifestyle measures prevent GDM?

12th October 2020, Dr Chee L Khoo

We know from various diabetes prevention programs that intensive lifestyle interventions can be successful in reducing progression to diabetes. As GDM is more common in women with higher BMI and in the many high- risk groups and it is logical to ask the question “can we prevent GDM in these women?” If we could reduce progression of patients who has prediabetes to diabetes, we should, in theory, reduce prevalence of GDM in women who are at high risk of GDM.…

Temporal arteritis – which features help with the diagnosis?

11th October 2020, Dr Chee L Khoo

There are a few “rare” medical diagnoses that are stuck in our minds since medical school days. They may be rare but it’s important not to miss them. Temporal arteritis, also known as giant cell arteritis (GCA) is one of those not so common conditions. It is actually not that rare. It is the most frequent primary systemic vasculitis with an annual incidence rate of 15–25 per 100,000 in Caucasians ≥50 years of age and it primarily affects medium- and large-sized vessels (1,2).  When do you suspect GCA?…

Hypoglycaemia in non-diabetics – is it a problem?

hypoglycaemia

27th September 2020, Dr Chee L Khoo

We know that hyperglycaemia is associated with increased cardiovascular mortality. We also know that in patients with diabetes, hypoglycaemia is also associated with increased cardiovascular morbidity and mortality. What about patients who don’t have diabetes and have low blood glucose (<4.0 mmol/L)? I am sure we all have patients who do not have diabetes but on screening blood tests, have BSL lower than 4.0 mmol/L.…

Nasal saline wash – can it wash away Covid-19?

24th September 2020, Dr Chee L Khoo

nasal saline wash

Since Covid-19 pandemic started 6-7 months ago, there have been a deluge of reports coming out in the medical and lay press and sometimes it is hard to keep track of what is real and what is just logical. Because Covid-19 is primarily a respiratory pathogen, infection begins in the nasal and nasopharyngeal mucosa with high viral load especially at the beginning of the infection.…
