2016: the flashback
Hey all!
In this post, I just want to share a flashback to the year 2016 and what I have learnt through the journey of these 365 days.
In this post, I just want to share a flashback to the year 2016 and what I have learnt through the journey of these 365 days.
2016, you will be missed
Remember I promised 2016 was going to be awesome?
It was, it was. It was a beautiful year, personally.
Here's my year in review:

Create the change
Hello everyone
So it's the last day of 2016. And everyone is now talking about new year resolutions and stuff. But what do we want to resolve as medical students?
Remember the first day you joined the medical college? That day you promised yourself something. To be a good doctor one day and serve humanity. To study and work hard all day and night seven days a week and gain knowledge in every subject you study. You had taken your life- changing resolution on that first day itself.
I believe in change. I have always tried to explore myself and learn new things each day of my life. That's what we all should do. And not just in the initial days or weeks of the new year. Because you are known by your actions and not what you think.
So stop making resolutions and start taking your real life decisions. Change is the law of nature. Create the change in yourself each passing day for the better. That will make you feel good. And because your ultimate goal in life is not just to be a doctor but also be a good human being. Then one day you will be what you ever wanted to be.
That's all

LAP score
Leukocyte Alkaline Phosphatase score is used to differentiate a reactive process from chronic myelogenous leukemia. Here I just mention the conditions with high and low LAP score (not a mnemonic this time :p )
High lap score:
- Neutrophilia ( as in bacterial infections)
- Polycythemia vera (neoplasm of bone marrow)
- Blast phase of XML
- Hodgkin's disease
- Leukemoid reactions
- in newborns, children and pregnancy.
Low lap score:
- Chronic Myelogenous leukaemia (chronic phase)
- Paroxysmal nocturnal hemoglobinuria
- Hereditary hypophosphatasia
That's all
Happy Medicowesome :)

Normal pressure hydrocephalus
Hey awesomites
Normal pressure hydrocephalus is a type of brain malfunction characterised by:
- Dilatation of ventricles
- Distortion of fibres in corona radiata
- Normal pressure on lumbar puncture
- And a triad of symptoms:-
- Cognitive loss (dementia)
- Apraxia of gait
- Pee problems (urinary incontinence)
I have made a mnemonic for this triad. Since cephalus in hydrocephalus means head so here's a cap to cover it. Mnemonic- CAP
The main aim of treatment in this condition is to drain the excess of CSF. Surgical installation of ventriculoperitoneal shunt is the usual method which aims to drain csf into the peritoneal lining of abdomen from where it is easily absorbed.

Seasonal affective disorder
Hey awesomites
Seasonal affective disorder (SAD) is common in winters months when days are short and nights are long. It is caused by abnormal melatonin metabolism and the patient presents with acute depressive and atypical symptoms.
Here's a mnemonic for atypical symptoms of Seasonal affective disorder.
SAD
S- Sleepiness
A- Appetite increase
D- Decreased energy
Note: Treatment of this disorder includes exposure to bright light therapy. Melatonin tablets should not be prescribed in such cases.

Virchow's Triad Mnemonic (NEW)
Hey, guys Jay here!
Virchow triad is about the 3 reasons for Deep Venous Thrombosis.
So I remember it as,
HE'S Virchow.
H - Hypercoaguability
E - Endothelial damage
S - Stasis
Many people may have many mnemonics. But this is mine. Hope you find it helpful. :)

Complicated vs. Non complicated appendicitis
- Complicated appendicitis has a perforated or gangrenous appendix.
- Non complicated appendicitis has a non-perforated appendix.
The treatment plans are different too!
- Non complicated appendicitis needs an immediate appendectomy
- Complicated appendicitis need to go through an antibiotic course before going to an appendectomy.

Oxidase vs. Oxygenase
Another confusing yet very simple thing
It's not that hard to remember right?
Jay :)
- Oxidase does oxidation in Redox reactions.
- Oxygenase adds an Oxygen to the substrate
It's not that hard to remember right?

Neurotransmitters associated with sleep mnemonic
Neurotransmitters associated with sleep mnemonic
SAND
S- Serotonin: helps initiate sleep cycle and promotes wakefulness.
A- Acetylcholine: levels are higher during REM sleep.
N- Norepinephrine: levels are lower during REM sleep.
D- Dopamine: high levels responsible for arousal and wakefulness.
Note:
- The regulation of levels of Acetylcholine and Norepinephrine is an important biochemical trigger for REM sleep. Higher levels of Ach and lower levels of NE means there is increase in the time period of Rapid eye movement phase of sleep cycle.
- Serotoninergic neurons are present in Distal Raphe nuclei which enhances wakefulness. Thats why the 5-HT activity decreases during NREM sleep and becomes silent during REM phase.
- Dopamine agonists, such as bromocriptine, pramipexole and others are used to treat parkinson's disease which work by acting on dopamine receptors and compensate for the lack of dopamine which the brain cells no longer produce. They are used together with levodopa. By increasing dopamine levels they restore the balance of Acetylcholine and dopamine thus increasing wakefulness.
- Antipsychotic drugs are dopamine antagonists. So they decrease wakefulness and increase sleep time of a person.
- Higher levels of Ach during REM sleep is associated with erections in men.

Dehydrogenase vs. Dehydratase
Another simple thing that we often get confused with in Biochemistry!
- Dehydrogenase removes Hydrogen
- Dehydratase remove H2O
Simple right?
Jay
Synthase vs. Synthetase
This is very simple guys! Synthases don't use ATP to make the new bond between substrates while synthetases need an ATP.
ok fine! How to remember it?
Think of the additional T that comes in syntheTase is from ATP! ;)
Got a way to memorize it?

Enzymes and the Type of Reactions they Catalyze ( Part 6 : LIGASES)
Hello guys, we come to an end of this 6 part enzyme series and also this is the 500th Medicowesome post for 2016! Woohoo! :D
Ok, back to our business! Ligases, what to they do? Obvio, they LIGATE! Or simply connect! But connect what?
Think of these guys as a Plumber who connects those pipes! ;)
Major subclasses
Ok, back to our business! Ligases, what to they do? Obvio, they LIGATE! Or simply connect! But connect what?
Think of these guys as a Plumber who connects those pipes! ;)
Major subclasses
- Synthetase - Formation of new bond between substrates using the energy from an ATP
- Synthase - Link two molecules without using the energy from ATP (Confusing with Synthetase? They use ATP. Check here for a memory aid.)
- Carboxylase - Formation of a new bond between a substrate and a CO2 using the energy from an ATP
Are we ok guys?
Jay :)
Enzymes and the Type of Reactions they Catalyze ( Part 5 : ISOMERASES)
Ok what are isomers? Same molecular Formula, different structure! That is an Isomer! And presumably isomerases play with these isomers. But how?
- Racemase - Conversion of D isomer to L isomer or vice versa(Read about them here more in IkaN's article)
- Mutase - Conversion of one constitutional isomer into another. They shift one functional group from one place to another place within the same molecule.
Are we clear on this?
Jay :)
