"National Women’s Physician Day” isn’t about the 'Dr.' before our names.

It’s about the people we serve, the students we mentor, and the colleagues we lift up.

Our impact isn't measured by our titles, but by the barriers we break so that the next generation of women can simply walk through.

The goal isn't to be the first woman in the room; it's to ensure I’m not the last.

@DrBloodandGuts I wish there was a virtual option. Looks like a great course

[Mahum Nadeem @Mahum_MD]

@DrBloodandGuts What size OTSC did you use?

[Mahum Nadeem @Mahum_MD]

@DrBloodandGuts Is there an option for virtual participation? I couldn’t find it on the registration website.

The Difficult Colonoscopy is humbling to all endoscopists.

My Pearls :

#1 Female Patients
If hysterectomy or diverticulitis, use pedi colonoscope + water immersion. (Angulated colon)

If chronic idiopathic constipation or visceral obese, use adult colonoscope (redundant colon)

Fellow teaching: Here's a nice technique I picked up a few years ago from @KMonkemuller for tattooing the GI tract. Create a saline bleb, then switch to tattoo. Ensures tattoo stays in the submucosa & doesn't go to peritoneum. Especially useful in a moving target as shown below

Let’s talk thiopurines in AIH!

Thiopurine metabolism:
6MP/Azathioprine are metabolized into:

🔷 6-TGN (therapeutic metabolite)
🔸 Via hypoxanthine phosphoribosyltransferase
🔷 6-MMP (toxic metabolite)
🔸Via thiopurine S-methyltransferase

@DrDShaikh Great job! Very clean and sophisticated work

[Danial H Shaikh, MD @DrDShaikh]

⭐️Had the pleasure of performing the first case at Geisinger GMC using the Hybridflex knife by ERBE 🗡️—also my first time using this tool. Achieved en bloc removal of a LNPCP (rectum).

✅Pros: faster procedure with fewer instrument exchanges, controlled dissection with the shorter knife length, excellent stability, and held up well even in retroflex.

❌Cons: still needed a dedicated injection for initial SM lift (only saline via knife), and limited pre-coagulation on vessels due to smaller shaft size.

My heart break for all the young souls in Lebanon and Gaza 🙏🏻 Enough is Enough !

[Ihab Hassan @IhabHassane]

A heartbreaking and devastating scene: a Gazan child cries, "I want my mom," while his brother tries to console him.

Their mother was killed by an Israeli airstrike on their home.
