Tasman Medical Journal Blog Page

Welcome to Our Blog Page

Tasman Medical Journal welcomes you to our blog page.  Our purpose is to float and respond to respectable and scientifically justified but sometimes potentially controversial medical ideas in a way that avoids the need for peer review and stimulates discussion amongst our readers.  But we will ensure that a high standard of scholarship applies.  The rules for commenting are:

  • Submitted comments must relate directly to the blog post or formal paper under which they appear and should aim to maintain an acceptable level of academic discussion appropriate to a medical journal. 
  • Where comments are submitted in relation to a formal paper, the journal may publish the comment as a letter to the editor, on condition that full disclosure of your identity, professional qualifications and contact details is provided. 
  • If your comment makes a claim of fact, you must cite the primary source, just as you would for a paper.
  • A word limit of 600 will apply to comments. Where your comment exceeds this amount we may reject your comment and ask you to edit and resubmit.
  • Comments will be scrutinised to prevent publication of insulting or defamatory material, frankly unscientific or crank ideas or illogical claims, and to ensure the above rules is met. We may reject a comment outright without notification, or notify you to edit and resubmit the comment.
  • Tasman Medical Journal aims to maintain acceptable standards of well-written English. We reserve the right to edit your comment to maintain these standards, but may also reject your comment for the very same reasons and ask you to edit and resubmit.

To start things off we present two blogs, one on the contribution to annual global CO2 emissions from human breathing, and one on whether Herpes simplex viruses (cold sores) can cause skin cancers.

We look forward to hearing from you!

Current trends in COVID-19 infection and treatment

What is our current understanding of COVID-19?  A gigantic and possibly never-ending question.  It may appear that there is current COVID stability, but this is illusory, as new pathogenetic strains precipitating further pandemics are inevitable. What about the demand for booster innoculations?  Anti-COVID neutralising antibodies and clinical immunity produced by vaccines against SARS-CoV-2 virus are known to wane over a period of months.1  Antibody levels one booster dose after the primary series of vaccinations are fully restored but this effect also progressively declines.  Fortunately, the 3-dose regimen including RNA-based vaccines is also highly effective against severe disease and death from

No case for avoiding vaccination against COVID-19 based on alleged lack of vaccine efficacy

Widespread uptake of vaccination against SARS-CoV-2 infection is limited by a minority in the population who decline to be vaccinated.  The proportion varies between centres, and several reasons for non-vaccination exist or are stated.  These include social reasons, especially (in Australia) in remote indigenous communities; medical reasons in patients with impaired immunity and like diseases; distaste at administration of foreign compounds and other forms of disagreement with the principles of vaccination; and disbelief that in the case of COVID-19 the vaccines are effective, often conjoined with the belief that the vaccines are deliberately toxic or introduce toxic substances into the

Babi Yar, War in Ukraine, and the Tasman Medical Journal

War causes death, disease, destruction, despair and destitution.  It is a valid topic for inclusion in a medical journal. Spare a momentary thought for Mr Vladimir Putin.  He does not seem to realise that by invading Ukraine he may have signed his own death warrant.  A week ago he might have expected to live a full life, notwithstanding earlier adventures, and he appears not to realise that violent adventurism based on lies only ends in tragedy.  Mother Russia, whom he is indulging, exists only in the creative minds of Russian romantics.  How do we respond as doctors to such an

Will discriminatory public health policies based on COVID-19 vaccine status cause social harm that exceeds the benefit?

This Journal, in an early publication from the pen of the Editor (1) and at a point prior to the availability of vaccines against SARS-CoV-2 infection during which lockdown of citizens was taken to be the only possible mechanism for reducing community spread of the virus, noted that the wider economic and social impacts of such measures had been overlooked.  I stated “…The natural and expected political imperative is to prevent unnecessary infections and deaths.  However, this must be balanced against the adverse chronic consequences of economic shutdown, which will produce its own health hazards, especially in the area of

WA Government mis-steps in regulating community response to omicron strain of SARS-CoV-2

The Tasman Medical Journal is politically neutral but government decisions in health based on misapplication of science and/or causing widespread community confusion justify comment as they must have health consequences.  In a previous (1) and supplementary blog we summarised information demonstrating from four studies that the Omicron strain of SARS-CoV-2 is resistant to currently available vaccines until the “booster” or 3rd dose has been administered.  A further two studies confirm that conclusion (2,3).  Thus the description of double-vaccinated persons as “fully vaccinated” is wrong for the omicron strain, which is the strain currently feared most by the WA authorities. In

Omicron strain demands new terminology to describe vaccination status against SARS-CoV-2 infection

Recent papers1-3 have demonstrated and confirmed that the omicron variant of SARS-CoV-2, which is now the dominant strain worldwide, is resistant to neutralising vaccinations, and that immunity from two vaccinations is poor.  On the other hand, it increases substantially after a third administration. Garcia-Beltran and his colleagues1 state that, in a study of  239 vaccinees internationally, “…Taken together, our results indicate that two-dose mRNA-based vaccines are effective at inducing neutralizing immunity to SARS-CoV-2 wild-type and Delta variants but suboptimal for inducing neutralizing responses to the Omicron variant”  but that “…recently boosted vaccinees exhibited potent neutralization of Omicron variant pseudovirus that

CO2 emissions by humans caused by breathing

Atmospheric CO2  concentration is measured in parts per million, total tonnage and “emissions”.  There is a natural carbon cycle because plants can remove CO2 by photosynthesis.  It is suggested that in a “natural” world this cycle would be in equilibrium and that increasing CO2 concentrations are due directly or indirectly to human activity, either by increasing CO2 production (burning fossil fuels etc) or decreasing CO2 adsorption (by deforestation), of which the former is the greater factor.  However, this means that all sources of CO2 emissions need to be measured, and it is to be expected that the direct and indirect

Does Herpes simplex virus (HSV) cause BCC?

A staff member at the Tasman Medical Journal recounts having a solar-activated cold sore (presumed HSV infection) at the same site on the forehead over many years.  One year the lesion returned in spring as usual but its evolution differed from previous years. The herpetic crusting resolved but a patch of erythema remained at the site.  It was eventually biopsied and was shown to be a basal cell carcinoma which was resected.  The solar keratosis has not returned since, over a period of about 30 years. Viruses including HSV cause or are strongly associated with a variety of human cancers
