In an experiment involving the ever-unfortunate mice, the following steps occurred:
- Mice inoculated with influenza virus
- Th17 cells activated and migrate to respiratory and gastrointestinal systems
- Both respiratory and gastrointestinal tracts have mucosa, so they are similar in a way
- Th17 cells produce cytokines IL-17A and IFN-γ
- These cytokines mess with intestinal bacteria
- Results in less Lacto-, more Entero-
- Intestinal injury

Croup is formally titled acute laryngotracheobronchitis, but that’s a less catchy name.
It’s a viral upper respiratory tract infection that affects the larynx and trachea. It primarily occurs in children under 5 years old.
Croup attacks kids, so the acronym for symptoms must be in the appropriate theme.
- Coryzal prodrome
- Hoarse voice
- Inspiratory stridor
- Like a barking seal cough
- Difficulty breathing
- Single-dose corticosteroids of any of the following:
- Dexamethasone orally
- Prednis(ol)one orally
- Nebulised budesonide
- Single-dose nebulised adrenaline if severe
- Repeat after 30 minutes if no improvement
- Observe for 4 hours after administration
- ICU review if ineffective

A lumbar puncture is a procedure that involving drawing out cerebrospinal fluid, fondly known as CSF. For example, it can be used to check CSF for immune cells and glucose levels in suspected meningitis.
Lumbar puncture is considered an invasive procedure. But even with that aside, it’s not appropriate for everyone. That is, it does not suit all patients.
Contraindications to lumbar puncture are:
- Skin infection at the lumbar puncture site
- Uncorrected coagulopathy
- Increased intracranial pressure
- Trauma to the spinal cord

The Glory Of Acronyms
Cheap shortcuts to memorising important facts are a necessary survival mechanism in life.
Fortunately, in this case, there’s the powerful pairing of a nonsensical acronym with several respiratory illness-related pathogens.
When you mix that with pictures of knives, baked beans and a receding water line, anything is possible!
