1/Raise your hand if you’re confused by the BRACHIAL PLEXUS! I could never quite remember or understand it—but now I do & I’ll show you how
A #tweetorial on #brachialplexus #anatomy!
#medtwitter #meded #neurosurgery #orthotwitter #orthopedics #neurorad #radres #medstudent #FOAMed Image
2/Everyone has a mnemonic to remember brachial plexus anatomy. I’m a radiologist, so I remember one about Rad Techs. But just remembering the names & their order isn’t enough. That is just the starting point--let’s really understand it Image
3/From the mnemonic, we start with the roots—the cervical nerve roots. I remember which roots make up the brachial plexus by remembering that it supplies the hand. You have 5 fingers on your hand so we start with C5 & we take 5 nerve roots (C5-T1). Image

1/ If only there was a way to make hippocampal anatomy memorable!
Here is a #tweetorial of the basics of hippocampal #anatomy that will hopefully stay in your #hippocampus! #medtwitter #FOAMed #FOAMrad #medstudent #neurorad #radres @medtweetorials #Neurology @StefanTigges
2/Its name “hippocampus” comes from its shape on gross anatomy. Early anatomists thought it looked like an upside down seahorse—w/its curved tail resembling the tail of a seahorse. Hippocampus literally means seahorse.
3/In cross section, it has a spiral appearance, leading to its other name, Cornu Ammonis, translated Ammon’s Horn. Ammon was an Egyptian god w/spiraling rams horns. The hippocampal subfields are abbreviated CA-1, CA-2, etc, w/CA standing for “Cornu Ammonis”

1/Is remembering cerebellar anatomy making you dizzy? Need help telling your flocculus from your nodule?
Here’s some help w/a #anatomy #tweetorial on the 9 lobules of the vermis!#medtwitter #FOAMed #FOAMrad #medstudent #neurorad #radres @medtweetorials #neurosurgery @StefanTigges
2/Coming from anterior, the first lobule is the lingula. It sticks out from the front of the vermis & is connected to the superior cerebellar peduncle. I remember this bc it has a very appropriate name—lingula—it looks like a tongue sticking out of the vermis to lick the SCP.
3/Moving clockwise, next is the central lobule. I remember this bc it is positioned exactly how a central lobule should be positioned, in the driver’s seat—where the front seat driver position would be if the vermis was a car—up front, looking out the windshield over the lingula

📌How to design a brain 101🧠🏗️

A 🧵 on how I use @powerpoint to create illustrations

🎨Key tools and my 2 secret weapons:

-@gboulouis adding "advanced" stuff
-@MVarkanitsa reviewing every little detail

#MedTwitter #MedEd #NeuroTwitter #NeuroRad #Neurology #neuropath #FOAMed
This 🧵 is inspired by a great recent post from @teachplaygrub, since we are using similar methods and tools on #PowerPoint!

🛠️ The Basic Toolkit:
-curve function ➰
-edit points function✴️
-Layering 🃏
-Zooming (x300-400%) for details 🔍

1/ Is the voice box a black box for you?! Let's open the pandora's box of the anatomy of the #larynx together

An introductory #tweetorial on laryngeal #anatomy and the supporting structures. #FOAMed #medtwitter #meded #neurorad #HNrad #FOAMrad #medstudenttwitter @MedTweetorials
2/Everyone needs some support. Just like the tongue is supported by the hyoid, the main laryngeal support is the cricoid cartilage. It's like your favorite chair, with all the remotes next to it--not only does the cricoid provide support, it also connects structures in the larynx
3/ Although not official, the cricoid is like the real first ring of the trachea. Except it has an odd signet ring shape. The bulbous back part that makes it look like a signet ring provides the important articulation with the arytenoids

#POCUS #MedTwitter #Nephpearls
Many #VExUS enthusiasts asked for a #tweetorial on image acquisition pearls. Did one b4 but time for an updated one 🧵

#1 Let's start with basics
Color Doppler identifies the flow + tells the direction (blue is away & red towards the probe [BART])
#2 👆BART holds good unless u invert the scale.
👇Pulsed wave Doppler (PWD) depicts blood flow at a certain point (sample volume) - we analyze the pattern of flow + velocity using this mode.
Above-the-baseline = flow towards the probe (like red on color)
Below = away (like blue)
#3
While performing any Doppler study, it's important to keep in mind that the angle between US beam & blood flow determines the accuracy of velocity displayed. Parallel = best, perpendicular = worst
As #VExUS does not rely on absolute velocities, its OK not to have perfect angle

#POCUS #echofirst quiz:
In this PLAX view, what structure does the arrow indicate? + what's abnormal about it (if any)?
Clinical: 71y pt with fever/cough, initially thought to be pneumonia, later developed chest pain. BP 134/83 Pulse 106
Will post the answer/source tonight
#MedEd
Tweet 1/3
Answer:
Dilated coronary sinus with a mobile echogenicity (vegetation/infective endocarditis in this case)
Full case: 🔗ncbi.nlm.nih.gov/pmc/articles/P…
From #POCUS standpoint, 2 main causes: persistent left superior vena cava & pulmonary HTN. This pt had the former.
2/3
Normally on PLAX view, coronary sinus is barely visible. But when dilated, it can be confused with descending aorta (esp. by users who never encountered this scenario)

We will start with normal Normal #IUS #anatomy superficial mucosa (white) ...
#IBDtwitter

In ileocecal #Crohn’s disease, typically all bowel wall layers are involved. #IUS shows marked mural thickening, predominantly in the terminal ileum, cecum & appendix can also be involved.

One of my favorite topics in #POCUS - various effusions seen from different sonographic windows.
Here is a thread 🧵with labeled images for those interested.
1. PLAX view - pericardial effusion - anterior to descending aorta ⚫️below LA), wedge shaped

2/ PSAX papillary muscle view
LV is think as many of my patients have #CKD and LVH (as well as mitral annular calcification seen on PLAX view above)
#Nephrology #POCUS
3/ Apical 4-chamber view
Sometimes, effusions may be missed due to inadequate visualization of ventricular free wall/lung interference. Always pay attention to the RA area

I'll be adding short important points which would hopefully help in remembering certain concepts during #PLAB preparation, to this thread🧵every now and then as I take them out from my scattered notes. Feel free to comment your tips and tricks which would help others, as well 👇
Please don't take any of these as medical advice 😂🙏. Real life stuff is much more nuanced. These are just clinchers for the sake of the exam.

1. Drug contraindications...
-Avoid BAN drugs in Asthma (Beta blockers, aspirin, NSAIDS) &

Abrimos 🆕 🧵 con algunos de los puntos más interesantes y comentarios extras.
¿Podrás mejorar tu desempeño en 👁️👁️‍🗨️?
A manera de introducción se mencionaron los temas a tratar. Utilidad indiscutible en el paciente neurocrítico.
Antes y durante de 1999 se estaba ocupando el modo B para la evaluación ocular, posteriormente se adicionó el Doppler Color y Pulsado y el Modo-M.
Los tiempos cambian.
En el 2020 el Dr. Patrick de #PedsICU 🇵🇪 público, en base a un caso clínico de amebiasis cerebral, un artículo acerca de monitoreo invasivo y no invasivo en pediatra.

Buckle up! This 🧵 is a deep dive into the #physiology of defecation, the mechanics of pooping! 🧰 🚽 💩

nature.com/articles/s4157…

#medicine #MedEd #science #GITwitter #GI #gut #motility #constipation #IBS
Defecation requires
1. intact #GI tract
2. coordination of many systems: neural (enteric nervous system, modulated by the peripheral somatic, autonomic and the CNS); muscular (smooth and striated); hormonal (endocrine and paracrine); and cognitive (behavioural and psychosocial)
#Constipation is the3⃣rd most common #GI symptom

💰 Annual cost of fecal incontinence and constipation: $1,594 - $7,522

#HumanAnimalEntanglement. - Today: "The Curious Case of the #Dancing #Cranes".

1/ Among the many naturalistic animal depictions at early #Neolithic #GöbekliTepe in southeastern Turkey there are some bird depictions with suspiciously odd legs ...
2/ Generally, birds seem to take up a noteworthy role in the iconography at #GöbekliTepe (and other related #Neolithic sites).

The #cranes mentioned above in particular stand out due rather muscular legs and what seems a more human-like #anatomy, including 'knees' and 'toes'.
3/ Do these #crane representations evoke the impression of #masked people?

Yet it was suggested that this even could be more than simple #masquerade: The visualisation of a transformation into the animal itself in the course of #shamanistic rituals?

#Vedic texts suggest that #Hindus originally did not worship idols and build #temples, and it is quite likely that both Hindus and #Buddhists got the idea from the #Greeks.
#India accounted for 33% of the #World economy in AD 1.
#China's share was 26% of World GDP.
India was by far the World's economic superpower at that time.
#Indians sold textiles, spices and demanded precious metals in payment.
Not a year passed in which #India did not take 50 million sesterces away from #Rome.

1/ Thought of doing a quick #tweetorial on image acquisition for #POCUS friends starting to do #VExUS
It's kind of "how I do it" guide and not necessarily optimized for research.
1st: Look at the IVC in both long and short axes
If big, do further scans 👇 #MedEd #FOAMed
2/ Lateral approach works best to obtain a straight segment of the portal vein (straight = best Doppler shift) and a nice hepatic vein too.
Place transducer approximately in the anterior axillary line pointing towards sternal notch. Then fan antero-posteriorly.
#POCUS #VExUS
3/ Forgot what is fanning?
Its also called tilting or some people say, "look" in a particular direction from the same spot.

Check out my illustration on the course of the oculomotor nerve with its associated sites of injury!

Patients with an oculomotor (CN III) nerve palsy can present with binocular horizontal, vertical, or oblique diplopia and ptosis. (1/3)
In addition to extraocular muscle weakness, one may find a dilated pupils (mydriasis) due to unopposed sympathetic innervation to the pupil. Having an understanding of the course of the oculomotor nerve, and where injury can occur, leads to the production of a (2/3)
differential diagnosis, ordering appropriate diagnostic studies to confirm the cause of oculomotor nerve injury, and implementing appropriate management to best serve the patient. I hope you all enjoy it! (3/3).

Neuroanatomy TOTD #15🧵
The inner ear #tweetorial--it packs a large functional punch for its small size-strap in!

To evaluate the t-bone, best to compartmentalize--external/middle/inner ear (IE). See previous #tweetorial of the ME. The IE is difficult as most structures are obliquely oriented (at different obliquities!)-and can be hard to see on standard views. 2/24
IE communicates with ME via oval&round windows (which allow for transmission&dissipation of sonic vibrations). IE houses sensory organs for hearing/balance/sensing motion. The cochlear&vestibular nerves (CNVIII) transmit signals to the brain via the int auditory canal (IAC). 3/24

New Paper: 1st dinosaur from #IsleofEigg! We describe a limb bone, & attribute it to a Middle #Jurassic stegosaur! Thread👇 [1/7] #StEiggosaurus #Fossils #Scotland #dinosaurs #FossilFriday
I discovered the bone on @NatGeo funded #fieldwork in 2017. #IsleofEigg is known for #Jurassic marine reptiles & fish #fossils (found by Hugh Miller & others). It was collected by a team frm @GeosciencesEd & Staffin Dinosaur Museum. #StEiggosaurus [2/7]
The bone was badly eroded, but @MrIchthyosaurus carefully prepared it for the team to study. We combined our expertise in #Mesozoic reptile #anatomy and bone microstructure (#histology), to narrow down the identification. #StEiggosaurus #fossils [3/7]
