These are artifacts that occur in the blood smears of patients with chronic lymphocytic leukaemia. They happen because the cells are rather fragile.
Memory aids make life better.

There are many things that can go wrong in the human body. Luckily, there’s a specialty that studies it: pathology. After all, a tissue diagnosis must be made! The show must go on!
In this episode, Dr Nicky talks about work, microscopes and social interaction in the specialty of pathology.
About the guest speaker
Dr Nicky Graf completed her pathology training in 2000, and has been a staff specialist (Anatomical Pathology) at The Children’s Hospital at Westmead since 2001, with a specialty focus of paediatric and perinatal pathology. She has been the department head for the past 10 years (since Oct 2007).
Dr Nicky has a particular interest in paediatric tumour pathology and renal pathology, but covers all areas of paediatric and perinatal pathology practice. Her department is one of three sites (although the largest with regards to case load) servicing the newly created state-wide perinatal pathology service.
Dr Nicky’s interests are reading, spending time with her family, skiing (snow) and travel (recently went to Antarctica – amazing!).

GSD is a genetic disease characterised by missing enzymes. Inheritance is typically autosomal recessive.
GSD involves disrupted glycogen metabolism. It makes glycogen accumulate or not form properly, so the glycogen cannot be broken down into glucose or stored like normal.
Treatment can include dietary modification.

Do topical NSAIDs increase the risk of skin cancer? After all, NSAIDs dampen inflammation and immune suppression is a factor that can promote malignancy. The answer is no!
For, on the contrary, research focuses more on the potential of using NSAIDs in the fight against cancer. How can this be?
Think of the mechanism of NSAIDs. They’re non-steroidal anti-inflammatory drugs, meaning they’re medications that reduce inflammation without being from the corticosteroid class.
NSAIDs indirectly inhibit prostaglandin synthesis by directly inhibiting COX enzymes. This provides anti-inflammatory effects and analgesia.
Prostaglandins play a starring role in situations such as fever.
In contrast, other things that are associated with increased malignancy risk have different ways of working.
For example, HIV impacts CD-4 T cells.
Meanwhile, chemotherapy agents have different mechanisms. For example, vincristine disruptively acts on microtubules.
Let’s not forget UV rays, which wreak havoc on the DNA process by inducing mutations.
These are just some of the villains of medicine. Thankfully, there are emerging medications that meet them in combat. But that’s a story for another day!
