Calot's triangle vs Cholecystohepatic triangle

Hello Awesomites!

I would like to highlight difference between these two terms. It is confusing.

1.Cholecystohepatic triangle:

Medial boundary- Common hepatic duct
Inferior boundary- Cystic duct
Superior boundary- Inferior edge of liver

2. Calot's triangle:

Medial boundary- Common hepatic duct
Inferior boundary- Cystic duct
Superior boundary- Cystic artery

Happy Studying!

Efferent optic nerve fibres

It's interesting to note that the optic nerve, which is considered to be a purely sensory nerve has some efferent fibres, that is, fibres from the brain to the optic disc. The presumed role of these fibres is in dreams, where the brain sends impulses to the retina, image is generated and it is carried back to the brain via the afferent fibres.

CEAP classification of Chronic venous insufficiency

Hello Awesomites!

The classification and staging of chronic venous insufficiency (clinical severity) can be measured by a scoring system called clinical manifestations, etiological factors, anatomical distribution, and pathophysiological conditions.

Happy Studying!

Anterior chamber associated immune deviation

Some specific antigens when placed in the anterior chamber of the eye result in a suppression of cell mediated immunity, with a normal humoral component.

There is something known as the ' oculo splenic axis' , whereby the antigens travel via the trabecular meshwork and reach the spleen. In the spleen, they secrete MIP 2 which attracts the NK cells. The NK cells in turn secrete IL10 and TGF beta. The T cells in this environment become regulatory cells and suppress the cell mediated immunity. Production of IL2 is suppressed.

The eye is an immuno privileged organ, as it needs to be structurally maintained pristine to preserve it's light carrying capability. ACAID is a mechanism by which Nature attempts to limit unwanted inflammatory responses in the anterior chamber.

It has implications in intraocular tumors, autoimmune, and infectious immune responses.

-Sushrut

PS- The failure of ACAID in the mechanism of lens induced uveitis still remains unexplained!

What it takes to be a compassionate physician

Hello everyone!

I participated in the Daniels Family Foundation Scholarship in honor of an honorable physician at my program.  The requirement to participate was to submit a brief (500 words or less) essay that describes how you have demonstrated what it takes to be a compassionate physician dedicated to the practice of general internal medicine.

If possible, I want you to write an essay too. Please email them to me (medicowesome@gmail.com). I would love to hear your experiences (and maybe even publish them on Medicowesome if you'd like)

Let me go first and share my essay with you:

Authors diary: Are you ready for solo practice?

"Are you ready for solo practice?"

My father read out the topic from a WhatsApp forward he had received.

I was drinking tea, with all the absent-mindedness of a resident who barely has the luxury to sit down and have said cup of tea.

I stared at my father aghast, wondering where this daunting question sprung from, till he elaborated that it was the topic of an essay competition.

As I read through the message myself I corrected him, "That’s not what it says! It's asking whether you're adequately trained for solo practice in the future."

"Your future is just a couple of years away. Will you be ready by then?" he asked.

"I don’t know about ready, but I’m sure I’ll be adequately trained," I answered.

He nodded and after a beat, leaned in and asked,
"But have you really thought about it yet?" ((And what makes you so sure? Have you really thought about it yet?))

That got me thinking indeed.

As a year old paediatrician, the most important lesson I learnt was how much there was to learn. My days were spent working with any time off work spent catching up on missed sleep. I felt like I whizzed through my first year, barely retaining any of the knowledge I was expected to glean as an intern. Being a houseman had felt like operating at spinal level, for the lack of there being a synaptic level
any lower than that. Perhaps I wasn't ready at all.

My face seemed to betray my thoughts as my father interrupted them. "Instead of lamenting over what you haven’t learnt," he asked kindly, as if reading my thoughts, "Why don’t you try and think about how much you have?"

Convinced that I had learnt nothing of value anyway, I decided to humour him nevertheless. I spoke about  my housemanship month by month, about what each sick child and each hopeful parent had taught me. A resident doctor in a busy municipal hospital barely gets time for their own basic life needs like food, sleep, or even a bath (and needless to say, sleep always takes priority!). Most of what we learn is on the go. Nobody gets enough time to go back and read about the cases we've seen in the ward. Thankfully the vast number of cases and immense workload ensures that we at least know how to manage basic ailments that a child presents with.
However amidst putting orders, histories, and ensuring investigations for so many patients, we forget to learn about the little things - how to allay a parent's concerns about their child, how important the so called 'cosmetic' part of our practice is. Of course, all these concerns are still things that can be worked on if one can put their heart into it.
And yet, are we being adequately trained to do this for future solo practice? The answer, shockingly, is a resounding no.

Add to this, we're barely trained to make decisions by ourselves, especially when there are so many seniors waiting to teach us, guide us, and by extension, take responsibility for our actions. How is one supposed to adjust to suddenly being so independent?

In a tertiary care setting, we are used to sending out references left, right, and centre. We fail to learn the basics of anything that would result in us putting even one toe out of our own speciality and instead rely on the services of others, who are just a single written call away. It's very obvious that this is not going to be the case when one starts practising by oneself.

Another important thing that nobody teaches you in residency is how to ask for remuneration for our services. Being employees of the state or the corporation, we are used to working endlessly for a fixed salary being ddeposited in our accounts each month. As a result, we fail to realise our worth in monetary terms, there being a certain amount of guilt with each patient we charge. Maybe this is something we realise only after getting into private practice, where taking care of every patient is translated into putting food on our own plate. At this stage in life, while I hope I wouldn't underestimate and thus undercharge for my abilities, I really don't know what that would be like be like.

So, coming back to the question that started it all - no, I am not adequately trained for future solo practice. And no, I am not ready for it either. But two years down the line, I have hope for the former statement. And as for the latter? Well, I believe that at least that "I'm not ready." will transform into" I'm not ready...yet. But I'm willing to stick around till the day I am."

EPISODE 04 - INTERNSHIP DIARIES (What will I do with your blood? -Vials and sampling)


- By Upasana and Jay

It has been a tired day at the hospital. You are almost at the end of your day of duty when your senior resident asks you,

“Dr Kesh, can you please prepare the Laboratory forms, sign them for me and then, submit these blood samples to the Main laboratory?

“Yes sir!” You pressure a smile and look at the blood samples and the empty Laboratory request forms needing your signature and your gleaming new stamp with your licence number.

You sit down to prepare the blood samples.

Thursday, July 4, 2019

EPISODE 03 - INTERNSHIP DIARIES (Let me gain access into your veins)

(Lesson 1.2)

Inserting an IV line or an Intravenous line is a very much of an expected skill from a Medical professional. Although often performed by Nurses, the skill can come handy at any time because in a case of a hard insertion the nurse or the ancillary staff may refer the patient to you to perform.

Before inserting an IV line you need to know what is an IV Cannula or an IV Catheter.

A cannula or a catheter is a small tube made out of medical grade materials that would allow a medical professional introduce or extract a substrate to or from the body. In a case of an INTRA-VENOUS cannula the access is taken in to the VEINS.

Usually an IV cannula can be used to introduce IV fluids, IV medications as well as sometimes to draw blood(often at the insertion moment).

1. The catheter itself is composed of (a) a tip for insertion into the vein, (b) wings for manual handling and securing the catheter with adhesives, (c) a valve to allow injection of drugs with a syringe also called a LUER lock-valve, (d) an end which allows connection to an intravenous infusion line, and capping in between uses.
2. The needle (partially retracted) which serves only as a guidewire for inserting the cannula.
3. The protection cap which is removed before use.

(By courtesy of Wikipedia (
https://en.wikipedia.org/wiki/Peripheral_venous_catheter) retrieved 7/5/2019)

These cannulas come in different shapes and sizes, and the sizes are measured in BIRMINGHAM GAUGE SYSTEM often abbreviated as G. In this system the lower number is having a higher diameter and a higher number is having a lower diameter of the catheter tube. (This is different from French Gauge System where it is opposite from this numbering system and is often used in NGT tube sizes)

So, an 18G IV cannula is larger than a 20G IV cannula.

The recognizing of these cannulas are done by the colour of its Luer lock-valve or the tip of the needle in some varieties.

The colours are pretty constant throughout the world but sometimes it differs. So always refer to your senior before checking out a cannula for the first time or better yet, READ WELL of its packaging.

(Note that in some countries 26G could be of Purple colour)
- Table by courtesy of Wikipedia (Retrieved 7/5/2019) -


Check for your needed equipment and material.
  • Alcohol or Hand Sanitizer/Soap and water
  • An alcohol wipe. - To sanitize the skin
  • A tourniquet. - To block the venous flow and engorge the vein as well as fix it.
  • An IV cannula - As mentioned above.
  • A suitable plaster or a Tegaderm® - To fixate the IV cannula/catheter on to the skin
  • A syringe with normal saline - To flush the Catheter
  • A clinical waste bin with a sharp disposal section - To dispose the waste including the needle.

STEPS

  1. Identify a visible and/or tangible vein. Try to feel it. A rule of thumb is, the better you feel the vein the more successful your insertion will be.
  2. Once you identify the vein, apply the tourniquet and recheck on the vein if its engorged and tangible.
  3. Apply alcohol on your hands and clean it. Wear your gloves properly as explained before; in case you were already wearing gloves, check if you can request for a change of your gloves. Touching a patient without gloves is discouraged.
  4. Clean the patient's skin with Alcohol wipe, a cotton ball soaked in Isopropyl Alcohol 70% or Ethyl Alcohol 70% is alright.
  5. Before inserting the catheter and check if the catheter tip is clear without any manufacturer's defects such as a defect end. Check the needle for its bevel up. 
  6. Stretch the skin distally, and look for your insertion point. If your vein-in-concern is not much engorged you can try slightly tap on it.
  7. Tell your patient to expect a sharp pinch on their point of insertion.
  8. Insert your needle beveled up, usually around 30-45 degrees to the skin and advance your needle to see if there is a flashback of blood at the hub of the syringe.
  9. If you see the flashback, then advance the whole needle about 2-3mm and then retrieve the needle slowly and check if a streak of blood is following the returning needle. If it does...Congratulations! IF NOT, try withdrawing the needle a bit and change the position until you see the flashback.
  10. If you cannot do it while the needle is inside, then retrieve the whole catheter and re insert at a different point of a different vein.
  11. If you still cannot, then ask for help from a senior.
  12. In the fortunate incident of you are already inside the vein, remove the tourniquet and while removing the needle, give pressure to the top of the cannula tip already inside the body so the blood will not reek out making your field a mess!
  13. Insert your prepared flush into the catheter and try to inject. If it proceeds with no resistance, then you are good to go!
  14. Get your Primed IV line or HEPLOCK (which is used to administer IV medications in a later  time via the catheter and it will stop the blood from reeking out) or close the end with the white cap of the needle(Often used with those catheter types with Luer lock-valve where a heplock is not needed)
  15. Take your previously prepared Plasters or already opened Tegaderm® and secure the IV catheter on to the skin. There are several methods of securing the IV catheter on to skin using plasters. We will discuss 
  16. Dispose your needle to the sharps disposal.
  17. Clean and wash your hands.

Congratulations, you are done with your IV catheter/cannula insertion.

*******

You look at the face of the patient after finishing your work, and you are proud that you got access in one hit and did not spill the blood.

"Thank you doctor!" Your patient thanks you.

"You are welcome!" You smile and leave the patient with your tray.

Thanks guys for the support! Thanks for the messages you have been sending to my Whatsapp requesting for more articles. We will try to provide more topics soon. 

With love,

Fregoli and Capgras.

So this post is regarding Delusional misidentifiaction syndromes.
There are two of them i. e. Capgras and Fregoli syndrome.

Now both of them are super confusing and are often asked in entrances. I made a mnemonic to remember them. If you can remember any one of them, you can figure out other.

So I hope all of you are aware of GOT-Game of thrones! Remember Arya stark had face swaping ability? She killed entire Frey family by it. So did how she kill them? She disguised herself as head of the family - Walder Frey and killed them.

So take A from Capgras. Here A stands for Arya stark. Arya killed family of Frey by disguising as Walder Frey (Family member). So in Capgras, patient thinks that murderer is going to disguise as a  family member and kill him. Eg Nurse disguised as a wife to kill him.
Capgras is also know as The Delusion of doubles! 

OR (To non GOT fans)

FreGoli:
F= Family
G=Gun (In hindi you can simply remember Goli)
"Family members trying to kill patient with Gun but disguised as someone else"
Eg: Wife disguised as Nurse to kill patient (Husband)

"Valar Morghulis"

That's it

-Demotional bloke.

EPISODE 02 - INTERNSHIP DIARIES (Protecting you and myself)

NOTICE!

Awesomites, I'm super sorry for being super late, I was so busy with my MD graduation hence I couldn't update the promised topics on Internship Diaries. I will update as soon as possible all the topics we need to discuss.

With love,
Jay


(LESSON 1.1)
WEARING SURGICAL GLOVES

       There are three forms of wearing gloves. 
  1. OPEN, 
  2. CLOSED 
  3. ASSISTED. 


Closed is the most sterile method and used mainly in operating rooms where you wear gowns and glove yourself and asepsis is highly expected. 

You utilize the Open method in situations in wards, and other Non-OR situations. 

Assisted method is when someone else such as, a nurse or a fellow colleague will serve you the gloves and you simply slip your hands in.


OPEN method,

  1. Remove whatever you are wearing in your hands, including rings, bracelets and watches. Try to keep it free elbow-down.
  2. Wash your hands with soap, and use Sterilium(R) or Isopropyl or Ethyl alcohol 70%. (Using them will eliminate the remaining bubbles of the soap.) 
  3. Then wipe your hands with a sterile towel.
  4. You will take your surgical gloves, open the outer cover and bring the inner cover outside without touching inside the gloves. 
    Surgical Gloves Inner cover
  5. Leave it on a flat clean surface and open the flaps, and you will see two gloves one for the right hand and the other for left hand.
  6. You will also notice the sleeves of the gloves are rolled upwards. The inside out part is considered unsterile and the inside the roll part is considered sterile. 
    S = Sterile part   |    US = Unsterile part
  7. So you use your non sterile dominant hand, hold the glove from the non sterile outside part and slip over your non dominant hand. Do NOT flap back the sleeve because will get contaminated because you are not yet wearing gloves on that hand.
  8. Now use your non dominant hand with the glove on, and slip the four long fingers of your hand into the rolled sleeve of the other glove. Because it is sterile. Bring it up and slip the glove over your non gloved hand. And flip back your sleeve.
  9. Then use your newly gloved hand to roll down the sleeve of your other glove from the inside the roll.
You are successfully gloved!!!



In closed method someone will open the outer cover for you and you take the inner cover out, and wear it in such a way where you do not touch the glove at all skin-to-skin directly, but it will be discussed later. Too much info in one post will cause brain freeze. 

In Assisted method after gowning yourself, someone else will open gloves and serve you. Check if the thumb side is correct accordingly and slip in. If not you will be stuck and will need a new pair of gloves. Waste of time, waste of gloves and waste of effort!!

*******
You put on your gloves and see the nurse has prepared alcoholized cotton balls, 5 plaster strips of around 4 inches long and partially opened the IV catheter pack.

You take one alcoholized cotton ball and start looking for a vein.
[ To be continued... ]
*******
The answers to our previous questions regarding gloving are,
1. There are 3 methods
       1. Open
       2. Closed
       3. Assisted
2. There are 2 types of gloves
       1. Examination gloves - Often clean but not essentially sterile although some sterile varieties exist.
       2. Surgical gloves - Often sterile and comes in a tightly sealed pack. Do not use if the pack is already open.

What Is Going On In Fibromyalgia?

Hi there! Let’s talk about pathophysiology of fibromyalgia; a chronic disorder where fatigue and widespread pain feature prominently.

Current hypothesis says, it’s caused by aberrant peripheral and central pain processing.
Two key features are allodynia, that is, pain in response to a non-painful stimulus and hyperaesthesia, which is, exaggerated perception of pain in response to mildly painful stimulus.

Modern research says, certain antidepressants- with both serotonergic and noradrenergic activity- such as TCAs and venlafaxine, can relieve pain and other symptoms; suggesting the pathway involvement.

Some evidence says, alternative therapies such as acupuncture and spa therapies alleviate pain, which have been postulated to act via similar spinal pain-modulatory pathways.

CSF studies show increased levels of substance P, with decreased levels of noradrenaline and serotonin metabolites. All three are neurotransmitters involved in descending pain-modulatory pathways in the spinal cord.

PET images show an abnormal central dopamine response to pain.

The critical question here is: what is cause and what is effect?

Small sample size and short periods of study, remain the most cumbersome challenge to our complete understanding of fibromyalgia.  



Thank you for reading.

Mnemonic: Duke’s Criteria for Infective Endocarditis

Infective endocarditis is diagnosed using the modified Duke’s criteria.
Let’s look at them in an easy-to-remember way.

MAJOR CRITERIA
It’s, quite literally, proving the name Infective Endocarditis to be true.

Infective, that is, positive blood culture:
• Typical bugs in 2 separate cultures
• Persistently positive blood cultures, say > 12h apart
• Single positive blood culture for Coxiella burnetii

Endocarditis, that is, endocardium involvement:
• On imaging with 2D Echo or CT, look for vegetation, abscess, pseudoaneurysm or dehiscence of prosthetic valve
• On clinical exam, find new regurgitation murmur

MINOR CRITERIA
Remember, patients feel very ill when they have infective endocarditis.
Predisposing factors: congenital heart disease, prosthetic heart valves, iv drug abuse
Fever > 38 °C
Vascular phenomena: emboli, Janeway’s lesions
Immunologic phenomena: glomerulonephritis, Osler’s nodes

What if the blood culture is positive but does not meet the major criteria?
It’s considered as a minor criterion (casually speaking, problematic but not majorly problematic).

How do we use this for diagnosing?
2 major OR
1 major + 3 minor OR
All 5 minor criteria, make up the diagnosis.

Clinical Pearl: Fever with any new-onset murmur is taken as infective endocarditis, unless proven otherwise.



Hope this helps. Happy studying!

CABG For Undergraduates

CABG is Coronary Artery Bypass Graft; a surgical procedure where dying heart muscle is resupplied with blood.

Indications
[decided after a SYNTAX scoring system]
• Left main stem disease
• Triple-vessel disease involving proximal left anterior descending
• Patients unsuitable for angioplasty 
• Failed angioplasty
• Refractory angina

Procedure
• The heart is usually stopped and blood pumped artificially by a machine outside the body, a cardiac bypass. An alternative, that does not require this, is minimally invasive thoracotomy.
• As the graft, patient’s own great saphenous vein, internal mammary artery or radial artery is used. Multiple grafts may be placed. Arterial grafts last longer but may cause donor site numbness.

After CABG
• Continue aspirin 75 mg/day indefinitely. Consider clopidogrel, if aspirin contraindicated.
• Ensure optimal management of hypertension, diabetes and dyslipidemia.
• Counsel for smoking and alcohol cessation.
• Chart out graded physical activity through rehabilitation.
• Uncommonly, angina may persist or recur [from poor graft run-off, distal disease, new atheroma or graft occlusion]. If so, restart anti-anginal drugs and consider angioplasty.

Clinical Pearl: Recent randomised control trials indicate that early procedural mortality rates and 5-year survival rates are similar after PCI and CABG.

Understanding Refeeding Syndrome

Refeeding syndrome is a life-threatening metabolic complication of - stay with me - refeeding. It can happen via any route after prolonged starvation.

Who are at risk?
They’re patients with prolonged artifical feeding [parenteral or enteral], malignancy, anorexia and alcoholism.

Why does it happen?
During starvation, the body uses fat and protein for energy. There’s no carbs so there’s little to no insulin.

After refeeding, carbohydrate load causes a spike in insulin level.
Now first prof biochemistry tells you, more insulin means more cellular uptake of phosphate.
That’s it. That low serum phosphate level is the main problem.

How does it present?
Non-specifically and catastrophically. Features are rhabdomyolysis, red and white blood cell dysfunction, respiratory insufficiency, cardiac arrhythmias and seizures.
Left unchecked, it can lead to sudden death.

How do I prevent it?
Identify at-risk patients and give high-dose, high-potency Vitamin C and B complex injection, during re-feeding window.
Monitor vitals and labs closely. Close involvement of nutritionist is ideal.

What if it’s already happened? How do I treat it?
The biggest challenge is management of complications.
As regards phosphate, get the levels back up. Administer oral as well as parenteral phosphate, upto 18 mmol per day.


Thank you, that’d be all.
- Ashish Singh.

What are APS?

APS or Autoimmune Polyendocrine Syndromes are exactly what the name suggests.
They’re autoimmune in origin and they attack more than one endocrine system.


[Please click on the image to enhance it]

Let’s not forget autoimmunity begets autoimmunity.
APS are commonly seen with hypogonadism, vitiligo, alopecia, pernicious anaemia and coeliac disease, among others.


That’d be all. Happy studying!

Residency in India: Harassment, abuse and suicide

A few days ago, a resident committed suicide. One of us committed suicide.

In my opinion, it seems like the reason for the suicide was harassment, abuse, and excessive work load. If you ask any resident in any government hospital in Mumbai - they are all treated the same. The verbal abuse is probably different - They used casteist slurs for her. If you are privileged, they will call you different names.

How can we make sure this never happens again? Stop carrying forward the culture of abuse. It is high time. We have to fight the system. The past. The belief that it is okay just because it's residency. Don't look at how our seniors treated us but look at how we treat our juniors.

We need to treat each other better. Treat others how you would like to be treated yourself.

We need to help each other.

It is our fault that the life of an innocent was lost. It's because we didn't fight and we stayed silent when we saw abuse around us. We need to create awareness among medical students that will be joining residency. Let's talk about the abuse and how we can stop it. Residents should know who to report to without fear of negative consequences.

It will take time and it will probably not change in a day. But we are the future and we need to fight.
