Fact of the Day : Pantaloon Hernia

So this is just a very interesting fun fact.

When a person has a Direct Inguinal Hernia along with an Indirect Inguinal hernia , the person is said to have a Dual / Pantaloon/ Romberg / Saddle bag hernia.

Tried a lot to find out why the name is 'Pantaloon'. Pantaloon = Saggy pants or a Foolish old man. So take your pick !

That's all!
Happy studying!

Placenta Previa : Why it occurs.

Here's a short discussion post on Placenta Previa Etiology.

So Placenta Previa is a dangerous condition that presents with bleeding after 28 weeks up to the 1st stage of labour. (So it could so happen that the baby needs to tear it open and come out - as it may cover the Os. Hence Previa , where Previa means 'In front of'. Of course the reality being that the placenta gets compressed and results in fetal Hypoxia along with bleeding ).

The main pathology is that the Placental gets abberantly deposited / implanted in the lower uterine segment in stead of the upper.

This could be due to :
1. Decidual area being defective in the upper segment (Due to maternal age , Multiparity, Curretage or Cesearan section in the past).
2. Large placenta - due to which some part may encroach over the lower segment. (Multiple pregnancy, Smoking etc).

Here's a way to remember the risk / etiological factors for this condition.

Risk Factors for Placenta Previa -

Mnemonic : M4 C3

M - Maternal Age - Decidua becomes weaker with age so the placenta ends up encroaching over the lower segment.
M - Multiparity (Similar reason. Especially in a grand multi para)
M - Multifetal pregnancy (Twins etc. There's less space in the fundal area hence gets lodged in the lower segment)
M - Maternal Serum AFP (Indicates high/persistent Chorionic activity - essentially invades into more and more of the Endometrium.)

C - Curretage - in the past if done , damages the uterine layer making the upper segment defective.
C - Caeserean sections in the past / other operations on the Endometrium/myometrium - Makes the uterus defective.
C - Cigarette smoking - causes Hypoxia to the baby leading to Placental Hypertrophy - larger placenta occupies larger area and may encroach downwards.

Hope this helped !
Stay Awesome and
Happy Studying !

Step 2 CK: Algorithm for management of Atrial Fibrillation and Atrial Flutter

A patient presents with palpitations and irregular pulse-- What would you do next? The clock is ticking away.. and you might need to answer your multiple choice question!

This is a classic presentation of Atrial fibrillation - Palpitations and irregular pulse.
Next step in diagnosis: Do an EKG first--> if it does not show A.fib --> the next step depends on the patient's location --> If inpatient-> order Telemetry monitoring
If outpatient--> order Holter monitoring.

Now, once the diagnosis has been made, what they want you to know is the next best step in management.
The answer to this will depend on the HEMODYNAMIC status of the patient.
Patient can be either STABLE or UNSTABLE.
Now, what defines being UNSTABLE is any of the following:
* systolic blood pressure <90
* C.H.F.
* confusion
* chest pain

Once you know the status, follow the chart below.


Happy Doctors' Day!

Hemineglect mnemonic + clock drawing

Hemineglect - where is the lesion ? Which side is neglected?

Mnemonic: Hemineg-left. Left side is neglected. 

Lesion located in the right parietal lobe (non dominant lobe).

Interesting fact: Right-brain-damaged (RBD) individuals with spatial neglect often depict an object with left-sided features absent on drawing.

Usually, the patient is asked to draw a clock.
The drawing of patients with hemineglect contain empty space on the left, as if the clock were covered by an opaque semicircle.

However, this metaphoric occlusion frequently leaves the rim of the clock unaffected. The circular outline is rarely compromised in neglect patients’ clock drawings and is almost always the first feature produced in the task.


Interesting, isn't it?

Torn meniscus and inability to extend the knee

Doubt: Why does torn meniscus present with inability to extend the knee? I don't understand the anatomy correlation.

If there is complete tear, the meniscus (a piece of it) gets dislodged. It gets stuck in the knee joint.

This causes:
Inability to extend the knee.
Pain on extension of the knee.

Why is it called "bucket handle"?

A bucket handle meniscus tear represents a complete tear of the mensicus support or the ligament that holds the meniscus in place. This allows the meniscus to flop over like the handle on a bucket.  When the meniscus flips over it becomes stuck in the middle of the knee joint, you lose the ability to fully straighten the knee then you have a “locked knee”.

Explained by Dr. Mustufa Poonawala

The meaning of valgus (with doubt + mnemonic)

Meaning of valgus: A deformity involving oblique displacement of part of a limb away from the midline.

Doubt: Why is genu valgum knock knees? The knees (genu) are displaced towards the midline!

Answer: It's not the knees we consider during the deformity... It's the relationship of distal part with the proximal part at a joint.

Mnemonic: L in vaLgum is for Lateral displacement.

(Conversely, varuM is medial displacement.)

That's all!
Hate the inaccurate naming.

Study group discussion: Queckenstedt Sign

Suppose there is an obstruction to cerebral venous drainage in the left side, and u r doing an LP with manometry. If u occlude the left internal jugular vein, there will be no change in pressure but if u do it on the right side, there will be increase in csf pressure.

Response of Vagus to Systemic Injury.

Hello!

Let's learn/revise.

The vagus nerve exerts several homeostatic influences, including enhancing gut motility, reducing heart rate, and regulating inflammation.

Central to this pathway is the understanding of neurally controlled anti-inflammatory pathways of the vagus nerve.

This neurally mediated anti-inflammatory pathway allows for a rapid response to inflammatory stimuli and also for the potential regulation of early proinflammatory mediator release, specifically tumor necrosis factor (TNF).

Vagus nerve activity in the presence of systemic inflammation may inhibit cytokine activity and reduce injury from disease processes such as pancreatitis, ischemia and reperfusion, and hemorrhagic shock.
This activity is primarily mediated through nicotinic acetylcholine receptors on immune mediator cells such as tissue macrophages.

Furthermore, enhanced inflammatory profiles are observed after vagotomy, during stress conditions.

Rhinosporidium seeberi

Rhinosporidium seeberi

Hilton's law

Hilton's law.

The nerve which supplies a muscle of a joint, will also supply the joint and the overlying skin.
Conversely, any nerve that is innervating a joint will also supply the muscles of the joint and the overlying skin.

In humans, we find only 2 exceptions to this general rule:

1) Buccal branch of Mandibular nerve as we all know, pierces the Buccinator muscle. But it doesn't supply the muscle. The innervation of Buccinator is by the Buccal branch of Facial nerve.
2) Sciatic nerve in the Gluteal region....is very closely related to the Pyriformis muscle.... And may occasionally send a fibre that pierces the muscle. But it doesn't supply it. Pyriformis is supplied directly by the sacral plexus(the nerve to pyriformis).

Vasculitis Classification : A way out

Here's my way out of the necrotising vasculitis. Pan intended ;;).

So depending on the size of the vessel involved you can classify it as -

1. Large Vessel Vasculitis
2. Medium Vessel Vasculitis
3. Small Vessel Vasculitis

For the first two Remember :

TT PK

So Large vessel = TT
Takayasu Arteritis
Temporal Arteritis (Giant cell Arteritis)

And Medium Vessel = PK
Polyarteritis Nodosa
Kawasaki disease

Now Small Vessel Vasculitis can be classified further. It can be positive for a particular antibody called ANCA or it can be negative. This antibody is purely an association and not a causative one.

ANCA Negative : HCC

H - Henoch Schonlein Purpura
C - Cryoglobulinemia related
C - Cutaneous Leukocyto-angiitis

(Think of crying babies.
Cry = Cryoglobulinemia related Vasculitis
And another baby related Vasculitis​ is HSP).

Now ANCA positive Vasculitis can be either c-ANCA or p-ANCA depending on what part it stains.

Remember - WC
(Like Western commode)
Wegner's is c-ANCA.

Remember - PCM
p-ANCA in Churg Strauss and Microscopic Poly-angiitis.

Please note - The names of Wegner's and Churg Strauss have been changed to Granulomatosis with Polyangiitis , and Eosniophilic GPA respectively. This is said  to be because the scientist Wegener had been discovered to be possibly related to some Nazi war time activities and this opportunity was made the most of to also take a step towards  a more pathology-specific name-calling by altering the honorific name given to the disease.

That's all!

Pills of knowledge in Ophthalm- Retinal haemorrhages

1. Flame shaped haemorrhages are seen when they occur in the superficial layers of the retina because the blood can spread as tight junctions are not present there.

2.Dots and blots show up into the deeper layers because the space to spread for the blood is relatively lesser.

Step 2 CK: The algorithm to Management of Ventricular Tachycardia

Did you ever find it time consuming and confusing to answer the multiple choice questions about the "what will you do next" questions for different heart rhythm disorders?
Well, we did too. So, we are going to post some algorithms in subsequent posts, which will make it easier and save you some time in the preparation. They will guide your thoughts during those timed multiple choice questions.

Ventricular Tachycardia: It's a type of ventricular arrhythmia. The EKG is a must have diagnostic test. Look for wide-QRS-complexes. If the EKG is inconclusive--> telemetry monitoring should be done. If the questions asks, what is the most accurate test to diagnose this patient with V.Tach--> its Electrophysiologic studies.

Now, read very carefully the last line of the question as to what the question is demanding; it could be the next step in management or the test for a definite diagnosis.
The next (VERY IMPORTANT) step is to look at the vital signs and understand if the patient is hemodynamically unstable
(LOOK FOR :
               *IS THE B.P. LOW?
               *IS THERE CHEST PAIN?
               *CHECK THE Respiratory Rate- does the patient complain of shortness of breath/dyspnea,
               *LOOK FOR HIS MENTAL STATUS- is the patient confused/has altered mental status?                    *LOOK FOR SIGNS/SYMPTOMS OF CHF.
If any of these are present--categorize the patient as Hemodynamically Unstable.

And then, follow the chart below for management questions.

We all wanna help others; but do we help ourselves?

{This might be quite a descriptive post. So read this if you don't have exams upcoming recently}

As a Medical student, or a doctor we all are opting for a profession of care for people. But often we forget that the people who need care includes ourselves too.
How should we take care of ourselves.
1. One should take care of one's self.
2. One should take care of one's colleagues.

Do you eat well? Do you sleep enough? Are you spending time with your family? All these fall into such a level about taking care of your ownself.
As medical students we have long weeks and short sleeps. Let's admit, still we don't have enough time.

1. First of all, don't forget to,

EAT WELL. Food is essential for your sustenance. Eat nutritious food. Not just starch and sugary food. Opt for some fruits, yoghurt and more veges.
Our professor said it is better to get yourself a multivitamin complex if you feel like you are running out of enough nutritious food.

SLEEP WELL. Sleep is one of the most important aspects of your daily life. You probably cant sleep 6hrs straight. But get some decent sleep at least for 4hrs. And if you are taking a powernap, try taking it in multiplies of 90mins. I saw it recently in an article 90mins(180/270 etc) of nap improves your ability to wake up fresh as it is appox 1 sleep cycle.

EXERCISE WELL. You dont have hop into University gym and run on those treadmills for your dear life, but obvio try taking a stroll with your friends in the ground, or get a brisk walk to market instead of getting a taxi or riding there.

RELAX WELL. We surely don't have time to sit on a sedan chair and reflect on life or get a bikini/short picnic to the nearest beach when we have an Internal Medicine exam 3 days away. But surely you have time to go grab a coffee and enjoy it without looking at your jumbled up notes. (They aren't much readable anyways 😜jk...), Sit on a short wall and swing your legs like you remember all the drug regimes of the world. Look at the sky from the terrace and try to find a constellation or two that you learned in Grade school. Listen to a song that uplifts you or soothe you depending on your mood. Sketch something (personal secret : I sketch my crushes when I'm stressed 😜). Do something that makes you feel good. Meditation or yoga or something are good too. If spa, manicure pedicure, massage works for you, by all means go for it too.

CHECK-UPS. What is the last time you checked if you have enough Hgb count? Get your personal body checkups. You are only riding that Car, don't forget to check the oil and water levels too. Even a Benz or a BMW can wreck havoc if they don't have enough care. Get yourself done a teethscaling.

ENVIRONMENT. Look at your desk. Does it look like that you just performed an exocism there? 😂 Clean it up yo! Clean your desk. Your room. Keep some airfreshners, keep stuff that motivate you surrounding you. Not things that make you feel like "I'll rather live in the library!". 😜 Get enough Oxygen into your place and for all the love for Zeus, don't get into a room without enough ventilation.

MENTAL HEALTH. Almost every university provides free mental health counselling to its students. What was the last time you used it? Last time I had stress issues with my Neurology final exams, I went to meet a guidance counsellor. She totally listened to me and made me feel good. And another time when I felt like I'm losing my interest and the passion, I talked to my psychiatry professor.I think you should talk to someone qualified about it. And never think talking to a psychiatrist or a counsellor is a bad thing. In the long run it will help you heaps.

2. How to take care of your colleagues.

Ok we don't even have time for ourselves. I agree. But please don't leave those who are around you.

We all are in the same journey. Look out for them. Check if they ate their meals. If they forgot their attendance. Check if they are okay. If their relationships are going well. If they are performing fine in exam. Look out for people around you. Close friends are the first people are recognize depression and anxiety in a person before it attains to clinical levels. If you notice a difference talk to them. Or lead them to talk to someone qualified about it.

If someone is losing marks and failing exams offer to help them. If they ask for support never refuse.

Be a good person to others, this way you will be a good doctor too.

That's it for now folks. Enjoy and always take care of yourselves and others around you.

With love,

Jay

Answer is not always antibiotics!

Clinical vignette:
Young, non smoker, female comes with complaints of sore throath, dry cough, nasal congestion for 10 days. Now, she feels better however she coughs out yellowish expectoration.
There are scattered wheezes and crackles that clear with coughing.
You've ordered relevant labs and meanwhile the patient asks you if she would need antibiotics. What would your next step be?

Answer: Symptomatic management.
Reason: Since there is a history of preceding viral infection and her current situation indicated Acute Bronchitis, the expectant management would be fairly Symptomatic!
Infact, there are articles that state that giving antibiotics could worsen the patient condition! Also, judicious use of antibiotics can help prevent antibiotic resistance.

Let's fight antibiotic resistance!

Stay awesome!
