Because scrotal approach for biopsies could disseminate testicular tumors, Chevassu suggested inguinal exploration and occlusion of the testicular vessels before biopsy of suspicious lesions.
I use a pun to remember this - "Chew vessels" to prevent seeding: Chevassou.
Other facts you must remember are - Seminomas are radiosensitive. They respond to chemotherapy with cisplatin as well.
And that teratomas have frequent lymph node involvement.
That's all!

"PISS" is my memory aid for remembering, Parasympathetics make you Pee from S2 - S4 segments. (Two S's in piss, so S2)
So the opposite, sympathetic L1 and L2, allow urine to collect and are inhibitory to the detrusor muscle.
That's all!

Hey!
I focus on how to remember the doses of the medications in this post.
Atropine. aTWOpine. 2 mg IV every 5-10 minutes till full atropinisation occurs.
Pralidoxime is also known as 2-PAM. Two. So 20 mg/kg in 20 minutes is the loading dose. Half that, 10 mg/kg/hr is the maintenance.
Remember to remove the patient from further exposure and wash the skin, give gastric lavage.
Also catheterize the patient before atropine is given (viva concept).
For symptoms of muscarinic poisoning, the common mnemonics are "DUMBBELLS" and "Cholinergics make you leaky"
That's all!

| Tuberous sclerosis mnemonic |
Hello!
The mnemonic is, "EPIDURAL"
EP: Epidural catheter is Placed and anaesthetic is infused
I for Indwelling catheter for additional injections later
D for delay (A 15-30 min delay in onset is seen with epidural anaesthesia)
U for urinary retention, a complication of epidural anaesthesia (Another complication that you must remember is hypotension)
R for Repeated prolonged infusion that can be given with epidural anaesthesia
A for Analgesia (Epidural is used for labor analgesia, post op pain and cancer pain)
L for Lidocaine (The letter L has two lines, so two percent is the dose. Two also reminds me of Touhy needle, used for the anaesthesia)
Another commonly used anaesthetic is 0.5% Bupivacaine.
That's all!
*sings* I've become so numb

Happy Tuesday everyone!
The mnemonic for tocolytic drugs is, "ABC MNO"
A: Atobican
B : Beta mimetics like ritodrine (return to dreams)
C : Calcium channel blockers like Nifedipine
C : Cyclooxygenase inhibitors like Indomethacin
M : Magnesium sulphate
N : NO donors like Glyceryl trinitrate
O : Oxytocin antagonists like Atociban
A and O repeat twice, I wrote them anyway because they give a good flow :)
That's all!
I was asked an MCQ on this concept in my prelims. They asked which of the following drugs is NOT a tocolytic and they put 4 drugs. So it's important to know ALL the tocolytic drugs.

ACTH and MSH:
In Addison's disease, increase in ACTH causes hyperpigmentation because it is similar to MSH.
HCG and TSH:
Patients with choriocarcinoma can present with hyperthyroidism. It's because HCG is similar to TSH.
Pitocin and pitressin:
The drug oxytocin can cause water retention because it is similar to vasopressin.
These are all I can think of for now, lemme know if you guys know any other hormones that are so similar that they are able to cause similar effects in our body.
