Ghon's complex in primary tuberculosis mnemonic

The mnemonic is, "GHONS"
GHoN for Giant Hilar lymph Nodes and lymphatics.
S for Subpleural parenchymal lesion.

Remember that the subpleural lesion is located in the lower part of the upper lobe, upper part of lower lobe or the middle lobe.
 
We are so used to learning that tuberculosis bacilli love living in the aerated upper part of the upper lobe that we might, by mistake, choose that option in a MCQ asking about the primary complex. Keep in mind that the infection in upper part of upper lobe is secondary reactivation TB, not primary.

Mnemonic for Ghons focus vs Ghons complex: 
Ghons compLex consists of Lymph nodes and Ghons focuS is just the Site of primary lesion in the lung. 

That's all!

Filariasis mnemonic

Hi everybody!
These are random mnemonics I use to remember certain points about filariasis. Not sure if it'll help everybody. But uploading anyway!

"Filariasis fills the blood at night."
To remember that Microfilaria can be demonstrated in peripheral smear only at night.

"Microfilaria fills microvessels (capillaries) of the lung"
And cause tropical pulmonary eosinophilia!

Manifestations of filariasis
Remember 3 L's:
Lymphatic filariasis (caused by Wuchereria bancrofti and Brugia malayi)
Loiasis (caused by Loa loa)
Light (light, sight, blindness - river blindness caused by Onchocerca volvulus)

So complicated names!

Diethylcarbamazine dose mnemonic:
DEC, D-E-six, 6 mg/kg for 21 days.

That's all!
