Osteoarthritis

Arthritis is a term used to describe several inflammatory conditions affecting joints. As is so often the case with medical history, the name was derived from observed symptoms but subsequently it was found these were the result of a plethora of different causes. Today, “arthritis” covers around 100 different conditions associated with joint disease. RheumatoidContinue reading “Osteoarthritis”

Homeopathy Awareness Week

It’s world homeopathy awareness week and so I thought I would oblige and make people aware of one of the most prevalent and pernicious forms of alternative medicine in existence. There are many who steadfastly believe in homeopathy even though the foundations not only have no basis in reality, they are really quite bizarre. PreparationContinue reading “Homeopathy Awareness Week”

Controversial Alzheimer’s drug

Last year a new drug to treat Alzheimer’s arrived on the scene called aducanumab, trade name Aduhelm, made by Biogen in Cambridge Massachusetts. It’s claimed this drug is different to its predecessors because it targets the causative biology of the disease – but it’s not without some controversy.

The world’s most expensive drug is not a drug

Reports have appeared in the media recently headlining “the world’s most expensive drug” The subject of these headlines is Libmeldy, but the media seems obsessed with its cost, rather than what Libmeldy actually is.

I once attended a lecture by Martin Rees, the UK’s Astronomer Royal, who astonished theContinue reading “Covid-19 and the brain”

Spinal muscular atrophy and Zolgensma

Reports have appeared in the UK media of the NHS administering the most expensive drug in the world to a 5-month-old boy.

A Crisis of Infection

It’s amazing what humankind can achieve with the right amount of political will and resources. After the attack on Pearl Harbor in December 1941, Roosevelt oversaw the rebuilding of the Pacific fleet in only 6-months. Driven by rivalry with the Soviet Union, Kennedy announced in May 1961, “…we choose to go to the moon …”Continue reading “A Crisis of Infection”

What has opioid addiction got to do with cats?

Cat lovers will know the effect of catnip on their beloved pets only too well. Catnip (Nepeta cataria) is a member of the mint family and along with a similar plant called silver vine (Actinidia polygamy) it elicits a feline euphoria followed by a period of placid tranquillity, lasting perhaps 15-30 minutes. The effects wereContinue reading “What has opioid addiction got to do with cats?”
