Exam Prep Hacks -Tips for a lazy person

Hola everyone!

This post is for those people who really struggle during exam time, not because they can't understand studies or are stressed, but for someone who is really lazy and no amount of stress can change that (believe me I'm one of those :P)

So if you're someone who puts on their best game forward during exams and becomes a ninja  - this post is not for you! :P

Okay, so you know your exams are just around the corner and you have shit loads of syllabus to complete and you know there will be last minute panic yet you do not make a strategy and  "go with the flow", completely regret it later and are desperate to change this.

Understand that this post won't make you active all of a sudden, this post is all about embracing your laziness and turning into an asset and to rock your exams always without being under constant stress ;)

Let's get down to the basics then.

1. Always set rewards for yourself.

Sitting continuously for 5-6 hours IS JUST NOT POSSIBLE. Your concentration span is of a fly and you get distracted very easily, so instead of setting a target of studying for 5-6 hours continuously and then being disappointed later, make short targets. Like finishing one or two topics in one sitting and then maybe watching an episode of friends or going out for a walk. This way you feel like you've "earned" the break and will keep you motivated.

2. JUST SWITCH OFF YOUR PHONE.

Let's face it. Our phone's are the greatest source of distraction. Be it a whatsapp text, facebook notification or instagram post, we are constantly checking our phones. Either turn the internet off or put it on do not disturb mode, check the phones during your breaks.

3. Exercise!!!

Okay yes I get it, how is exercise gonna help me study? Remember endorphins- feel good hormones? Yeah well, they are secreted whenever we exercise. Exercise also help increase the blood flow and makes us more active. So, go for a walk for 20 min, skip in your room or dance, Whatever keeps you going, believe me, it's really gonna help. Will increase your concentration too!

4. Coffee.

I do not need to explain this. This is like a godsent drink!!  Everyone swears by it, but honestly, whatever will help you stay up.

5. Make realistic targets.

DO NOT set your goals according to others. Forget how your roommate is studying, how the lights of the topper of your class is always turned on. You know yourself the best. Do what suits you. Set targets for yourself. Setting targets according to others will just leave you disappointed and demotivated. It's a vicious cycle. Don't do it.

6. Select a time best suited for you.

Decide if you're a morning or a night person. And stick to that. Again, do not follow others. If you're a morning person, sleep well in time and wake up as early you can. If you're a night owl, prolong your study for as late as you can. Push yourself a little. Lol, just a little though :P

7. Sleep is your best friend.

Haha. Sleep to your rescue. It has been documented that sleep is very important to convert your short term memory to long term memory, so don't shy away taking those naps! :P Lack of sleep will cause dark circles too :P

But obviously not too long, 4-5 hours is adequate during exam time :P

8. Good diet.

Last but the most important part. Keep yourself hydrated and try to have a healthy diet, something which isn't too heavy. Heavy or oily food will just make you sleepy, tired and of course gain weight. Keep drinking water and fluids. Your brain needs food to function!

Hope all these things help you guys in acing your exams!

So the next time someone calls you lazy, Be Proud ;)

The Basics : Deviated Nasal Septum

Hello

Deviated Nasal Septum - "Abnormal and asymmetrical alignment of the nasal septum that results in acute nasal obstruction and other symptoms of upper respiratory tract."

AETIOLOGY -

1. Trauma : Abnormal pressure ( lateral or frontal ) applied to nasal septum results in its deviation to one side or another.
- The lateral blow may cause displacement of septal cartilage from the vomerine groove and maxillary crest.

Groove on which septal cartilage sits ( encircled ) - lateral view
Diagram by IkaN.

- Frontal blow causes crushing injuries to the nose, usually occurs in sportspersons especially the boxers.

2. Developmental anomalies : Palate forms the base of nasal septum. Highly arched palate, cleft palate or lip, and dental abnormalities can all lead to deviation of the septum.

3. Racial factors : Caucasians have more incidence of DNS.

4. Hereditary : Familial predisposition.


TYPES of DNS -

1. Anterior dislocation : dislocation of nasal septum into one of the chambers. ( unilateral nasal obstruction )
2. C - shaped dislocation : simple curve to one side with compensatory hypertrophy of turbinates in other side. It causes unilateral nasal obstruction.
3. S - shaped deformity : causes bilateral nasal obstruction
4. Spurs : shelf - like projections may lead to headache and epistaxis. ( unilateral obstruction )
5. Thickening : due to septal hematoma

CLINICAL FEATURES of DNS mnemonic

TREATMENT - Only required if the symptoms are severe. The procedures are to be done once the patient is more than 17 years old.

- Septoplasty : The most deviated parts of nasal septum are removed and rest of the parts are surgically corrected and repositioned.

- Submucous resection ( SMR ) : Mucoperiosteal and mucoperichondral flaps that overlie one side of the septum are lifted. Most of the septum is removed and flaps repositioned.

Thats all
Hope this helped :)

C Peptide levels : An Overview

Hello everyone!So I ended up uttering 'C peptide' recently in my Medicine Viva and my professor screwed me over it.
(Clearly I didn't C it through :'D )
So I thought of doing a brief summary on it.
Here goes.

1. What is C peptide ?
- When pro- insulin is cleaved , it gives insulin and C peptide.
- C peptide in general has a longer half life than insulin and is easier to detect.
- The pathway is something like this :

Pre proinsulin produced in Rough Endoplasmic Reticulum of Pancreas --> Transported to the Golgi apparatus and cleaved to form Proinsulin -->  Packed into secretory granules --> In these granules proinsulin is converted to : Insulin and C peptide. 

- Traditionally it is said to have no intrinsic activity but recent studies say it might have anti oxidant and anti inflammatory properties.   

2. What does it indicate ?
- So , its presence indicates presence of Insulin in the body in a proportionate amount.
- Hence in a case of Hypoglycemia if C peptide levels are high, it's likely to be due to increased endogenous Insulin levels.

3. C peptide levels increased in -
- Insulinoma
- Sulfonylurea induced Hypoglycemia ( As they are Insulin Secretagogues)
- Type 2 Diabetes Mellitus ( Hyperinsulinism due to resistance)
- Insulin Resistance states like Obesity , PCOS , Cushing's.

4. C peptide levels reduced in -
- Type 1 Diabetes as Insulin secretion is reduced
- Latent Autoimmune Diabetes of Adult (LADA )
- Factitious hypoglycemia - Due to excess exogenous Insulin administration.
- Hypoglycemia due IGF secreting tumors.

So if you get a patient with Hypoglycemia with elevated insulin levels , C peptide levels help you decide if due to exogenous Insulin , or Endogenous Insulin  ( Sulfonylurea induced or Insulinoma).

Hope this helped !
Stay awesome.
Happy studying!

The Basics : Middle Ear

Hey Awesomites

In this post, I will be talking about the middle ear structures and its relations with its neighbors ( just a summary ).

The Middle Ear is an air filled and bilaterally compressed/ concaved cavity lined by mucous membrane located in between the external and internal parts of ear. It is divided into:
- Epitympanum or the Attic ( 6mm ) - lies  above pars tensa and medial to pars flaccida
- Mesotympanum ( 2mm ) - lies opposite to pars tensa
- Hypotympanum ( 4mm ) - lies below the level of pars tensa

BOUNDARIES of the middle ear ( homologous to structure of a cube ) :-

Roof : Tegmen tympani - a thin bony plate that is a part of petrous part of temporal bone, separates the middle ear cleft from middle cranial fossa.
- Infection in the middle ear may spread superiorly and lead to formation of abscess in the meninges ( especially Extradural abscess ), meningitis or if severe, it may even lead to abscess formation in the temporal lobe.

Floor : Jugular bulb - The middle ear cavity is separated from jugular bulb by a thin piece of bone that if deficient may lead to formation of a layer of fibrotic tissue and mucous membrane in between. The contents of jugular bulb are:
- Internal Jugular vein
- Glossopharyngeal nerve ( IX )
- Vagus ( X )
- Accessory nerve ( XI )

The tympanic branch of glossopharyngeal nerve enters the middle ear at the junction of the floor and medial wall to play an important role in formation of tympanic plexus.

Anterior wall : The upper part of the narrow anterior wall has two openings or tunnels for - ( mnemonic : TEA )
- Canal for Tensor tympani muscle
- Pharyngotympanic ( or Eustachian ) tube

The lower part of anterior wall is separated from the Internal Carotid Artery by a thin plate of bone. The ICA is surrounded by a plexus of sympathetic nerves that enter middle ear through openings in this bony plate to form tympanic plexus.

Posterior wall : Posteriorly, it is related to middle ear cleft ( Aditus, Antrum and mastoid air cells )
- Infection in this region may spread posteriorly into the sigmoid sinus ( in posterior cranial fossa ) and cause thrombophlebitis !!

Medial wall : Medially the middle ear cavity is related to the promontory, oval and round window

Lateral wall : Tympanic membrane separates the middle ear from the external ear.

A brief about the functions of middle ear:
On the incoming of sound waves, the tympanic membrane oscillates and these oscillations are sensed by the strongly attached and faithful middle ear ossicle, the Malleus. The sound energy is transmitted as such by the ossicles ( Malleus - Incus - Stapes ) to the internal ear for further processing.

The major function of these ossicles is amplification of sound waves - Tympanic membrane is 17 times larger than the oval window - So that means the sound energy is picked up by the larger area ( TM ) and impinged over a much smaller area ( oval window ) thus amplifying it 17 times.

In addition, the lever action of the ossicular chain is approx. 1.3 units. Thus the intensity ( force ) of sound waves/ vibrations changes ( increased by ~20 times ) and not the frequency !! If the sound waves are not amplified ( in case OC is removed ), the Air Conduction would be lost. So BC > AC and thus hearing would then be poor.


Thats all
Hope this helped :)

'A' wave in JVP : Mnemonic and explanation

Hi everyone. So JVP is one of the most theoretical clinical signs I've ever studied. And though parts of it are logical , I find it tedious to memorize all causes for a particular finding.
So I've prepared a Mnemonic for prominent a waves.
Here goes.

The A wave is a positive wave of the JVP.
It represents the Right Atrial pressure during systole.

Causes of a prominent a wave
Remember :
CRePT's

C - Cor Pulmonale
R - Right heart Failure
P - Pulmonary stenosis
T - Tricuspid stenosis
S - The S tells you it's Stenosis for P and T.

The a wave essentially represents the pressure in the Right atrium during systole.
So any condition that causes this pressure to increase would cause a prominent A wave.

Cor Pulmonale and RVF are basically congestion in RV causing elevation of pressure in the RV.
This means the atrium needs to pump with greater force into the Ventricle for the venous return to enter the Ventricle. This increases the RA pressure causing prominent a wave.

Pulmonary Stenosis leads to accumulation of blood in the RV and this follows a similar fate as the above mentioned causes.

Tricuspid stenosis causes obstruction to the flow of blood from RA to RV. Thus accentuating the pressure in the RA.

That's the Prominent a wave for you !

~~~~~~~~~~~
Now there's something called the Cannon a wave.
These represents contraction of the RA against a closed Tricuspid valve.
The causes of this include -
A- V dissociation.
Heart blocks.
Ventricular arrhythmias - V tach , Ventricular premature complexes and Ventricular pacing.
~~~~~~~~~~~
The a wave would be absent in Atrial fibrillation as the atrium is functionally not pumping at all , and just vibrating.

These are the a wave findings for you !
Hope this helped
Stay awesome.

In this post, I will be talking about the anatomical structures in the lateral wall of the nasal cavity. 

Clubbing : Why it occurs.

Hi everyone !
This is a short post on why clubbing happens.
So it's simple !
It's cause people like to go out and get drunk. 
Just kidding. Here goes.

1. What is clubbing ?
- It's the bulbous enlargement of the terminal digits​ and the nail bed.

2. What are its causes ?
- Symmetrical clubbing can occur due to a host of causes.
- To summarize :
  A. Respiratory
   : Lung  cancer
   : Suppurative lung conditions like   

     Bronchiectasis , lung abscess and Chronic TB.
    : Pulmonary  Fibrosis

   B. Cardiac
   -  Cyanotic heart disease
   - Eisenmenger Syndrome
   - Infective endocarditis

    C. GIT
     -  Inflammatory bowel disease
     -  Cirrhosis - esp Biliary

     D. Endocrine
     -  Thyroid Acropachy
     -   Acromegaly

3. Why does it occur 

So I've spent a lot of time researching theories on how clubbing occurs. And let me tell you in the start itself, they're not clear on why it occurs.
But what makes sense to me , I want to share with you'll! And it was an absolute pain to find something convincing enough. So just stick with me here ;;) 

So the crux of clubbing lies in vasodilation of the digital vessels causing proliferation of the tissue there in.
The most widely accepted theory right now is the megakaryocyte theory.

So in the figure above , the left side in white shows the normal course of a megakaryocyte through the blood. 

In altered  cardiorespiratory conditions , these large platelets either bypass the Pulmonary circulation owing to the shunting produced due to Heart defects or the lung parenchyma itself proves to be less to purify the blood of the platelets.

 This causes these giant platelets to go lodge into the digital circulation causing release of cytokines like Platelet derived growth factor (PDGF) and TGF beta amongst others. These GF's cause vasodilation and in return , nail bed proliferation and collagen deposition.

How do we explain the Clubbing in GI causes ?
IBD - especially Crohn disease seen to have thrombocytosis eventually which may aggravate the PDGF.
In cirrhosis of liver , especially biliary , pulmonary arteriovenous shunting is observed. This could result in the megakaryocyte entrapment as explained.

Another theory suggests inflammation triggers a vagal response causing Vasodilator effects. ( Neurogenic).

Other theories -
Hypoxia induced
Reduced ferritin related
Neurogenic
Humoral - various PG's and other humoral molecules.

The most widely accepted theory is the Megakaryocyte theory.

Hope this satisfied you ! 
Thank you.
Stay awesome.

Preparing for NEET - Part 2

Hello everyone.

So now for my part 2 post on NEET PG prep, I will provide you with a seventh month schedule, but before that let’s  talk about the pros and cons of joining classes and how to deal with studies if you don’t join one.

Now in my earlier post I did mention that classes will help YOU with only 20% of the entire prep that also with sustained proper attention in the 12 hour class with proper notes and revision.

     1. The biggest thing you achieve by attending class is that the professors don’t beat around the bush, they give you point to point details and explain the things which they know by experience that the students are bound to screw up the most.

This is not something you can’t achieve by your own.  If you can get your hand on any class notes, then that’s enough, just thoroughly read that book, be regular in solving mcq’s and discuss your issues in group chats or with your study buddies. This does take care of it plus you gain a lot more, because here you are actively seeking answers and not being spoon fed like in classes

If you don’t have any class notes and our reading standard books, I suggest only read the bold lines, don’t read anything else. If you clearly don’t know anything about a particular topic then only read it in depth.

2. Weekly test series and grand test with ranking. This is beneficial only if you stick to the schedule, sadly I feel only 3 out of 10 students are regular at these exams. Also even if you don’t join the regular course, you can just join the test series, which I feel is a great option .

The bad point is that sometimes students feel torn between their own study speed, the subjects they want to study first and the test series schedule. Sometimes the test series just overwhelms you a lot cause every week you need to prepare for a different subject.  This has happened to me, and I feel that if I hadn’t join the test series to begin with, maybe I  wouldn’t have been so confused as to whether what to study and what to revise.

So it’s very important that you all know your own study patterns and your comfort. Don’t do things just because everyone else is doing it.  Chart down your schedule, and once you start with it, stick to it. Don’t listen to people and try doing things their way, you are your own person and you are awesome.

NOW for the study schedule.  This way of prep is bold and ridiculous. Its exhausting and It will demand that you trust the process, but it will work. It was taught to me by one of my friend. Its esp for the ones who haven’t joined any classes.

·         This first phase is for you to grab onto all the possible books on mcq’s you can for the last ten year mcq’s. And then you go crazy, just solve the mcq. Don’t read the explanations. Just solve and solve, just  reading the answers. Thats it. This whole process should take you a month at the max of rigorous solving.

·         Take a break..chill out for a couple of days

·         Phase two. repeat the phase one, now I  have tried this. And by experience I will tell you this is when it gets tough, monotonous and downright stupid but keep going at it. This will take you two months max.

·         Breaktime

·         Phase three is when you repeat it all over again, but now you will see the difference. You will love solving cause now the answers will flow out of you. Cause you have just learned 30.000 important one liners of all the 20 subjects. This process will take you 20 days.

·         Phase four is when you read and solve your doubts, read any damn book you want. Search for pictures, make your own picture library.

Remember 75% mcq are repeats, so this plan is made in a way that you learn all of those 75% first

You need to solve atleast all the mcq a minimum of five times to score a decent rank

Your speed of solving should reach 300 questions in one hour with atleast 65- 70% right.

These above are your goals after you are done with phase four

Irrespective you choose to follow this plan or any of the tips in my part 1 post, or if you choose to modify it according to you. Remember the most important thing is that you have to be consistent and do smart studies and not study like a dog. Have your wits about yourself and don’t  waste your time on reading unnecessary details.

Thank you

Types of abortion: Explanation and mnemonic

Hello!
This video is on the types of abortion.

Paraneoplastic Dermatoses - Tripe Palm.

Hello everybody,

So from today onwards, I will cover a series of cutaneous manifestations of internal malignancies starting with the first one called Tripe Palm.

               (Image courtesy-Google)

(The palmar ridges are accentuated and resemble to the stomach mucosa of a ruminant-tripe.)

Tripe palm (also known as acanthosis palmaris and acquired pachydermatoglyphia) is a velvety thickening of the palms with a ridged or rugose appearance.

The term is derived from its resemblance to the stomach mucosa of ruminants (tripe).

It is associated with gastric or lung cancer.

In some cases, tripe palm is the initial presenting feature of the underlying malignancy.

Improvement of tripe palm occurrs in one-third of patients after beginning treatment for malignancy.

Hope it was helpful.
