Caffeine in Migraine!

Does Caffeine play a role in therapy of migraine? Or does it cause migraine?

Asking a doctor, he said yes caffeine heals pain in migraine attack. OK yea fine. But it can cause an attack too!! This is what I found something Amazing!

Migraine is a disorder characterised by acute pulsating headache, usually restricted to one side of head. Pulsatile dilatation of cranial blood vessels is the immediate cause of pain.

But we know headache is usually caused by vasoconstriction of cranial vessels and not vasodilation!
Actually, excess vasoconstriction or vasodilation, both cause less blood to reach brain parenchyma. This makes brain tissue cry for its necessary nutrients from blood!

In migraine there's excessive vasodilation of the vessels. So is the cause of acute pain. Caffeine constricts cranial blood vessels ( all other systemic vessels are dilated ). It is a CNS stimulant. (That's why we have more coffee at night while studying). :p

Now here comes the point. 1-2 cups of coffee (100-200mg) heal the pain by vasoconstriction. More than this will tend to decrease blood flow and so less supply to brain tissue.
That's why some people, who are in a habit of taking excess coffee or soft drinks, are more prone to headaches!

》 Caffeine is one of the constituents of medicines specific for treating migraine.

MIGRIL: Ergotamine 2mg, Caffeine 100mg, cyclizine 50mg tab.

VASOGRAIN: Ergotamine 1mg,  Caffeine 100mg, Paracetamol 250mg, Prochlorperazine 2.5mg tab.

CAFERGOT: Ergotamine 1mg tab. + Caffeine 100mg.

Other medicaments-
Crocin Pain Relief: Paracetamol 650mg + Caffeine 50mg tab.
Micropyrin: Aspirin 350mg tab. + Caffeine 20mg

PS: Remember, the moment you feel migraine symptoms, have coffee. It is the best and most effective way to heal pain, without significant side effects.

That's all
Thanks :)

Bromocriptine in Type-2 Diabetes Mellitus

Type-2 Diabetes Mellitus is a chronic metabolic disorder characterised by Hyperglycaemia, Insulin-resistanthe state, increased lipolysis, and high risk of cardiovascular disease! We all know that. And much more to it..
But how can Bromocriptine be used to control blood glucose levels in diabetics??

Increased sympathetic activity in diabetics leads to breakdown of fats and high levels of free fatty acids in blood, which makes them obese! Insulin resistance in turn activates endogenous glucose production cycles which  results in glucose intolerance and high risk of cardiovascular diseases, hepatic failure, kidney problems and other systemic abnormalities!

Bromocriptine-
• An ergot derivative
• Acts as a potent agonist of dopamine D2 receptors.

• Intracerebral injection of 0.8mg Bromocriptine mesylate- quick release formulation, in Insulin-resistant state, is given after first meal in morning within 2-hours of awakening.

• It acts in the Supra-Chiasmatic and Ventro-medial nuclei of hypothalamus and regulates circadian rhythm of Insulin sensitive-resistant cycles and controls Dopaminergic-Serotonergic neurotransmitter activity.

• Simply saying, Bromocriptine reverses circadian rhythm from insulin-resistant state back to insulin-sensitive state, thus decreasing blood glucose levels back to normal.

• It reduces blood glucose levels, but does not bring back to normal. That's why it is prescribed as an add-on drug with insulin or sulfonylureas. This makes an additive effect in the anti-diabetic therapy!


That's all!
Thanks :)

Hypertrophy- is it just all about size?

Hypertrophy is a form of cellular adaptation mainly seen in the nondividing tissues of the body. It simply means increase in the individual cell size. But, is this all about hypertrophy?

Carrier types mnemonic

Someone asked me to post a mnemonic for carrier types.. So I made one.

Just remember 2-3 examples from each category.

Healthy:

Mnemonic: PSM

Convalescent:
Cholera
Diphtheria
Dysentry
Mnemonic: CD

Incubatory:
Influenza
Measles
Mumps
Polio
Hepatitis B
Diphtheria
Mnemonic: IM PHD, also notice most of them are from the immunization schedule.

Gastric pathologies and blood group association mnenonic

Okay, this is a very simple mnemonic and I'm sure many people are already using it. Here it goes anyway. The blood groups associated with CA stomach and ulcer can get confusing so,
1. An ulcer is round, so it is more 
    common in people with group 'O'

2. CA contains an 'A' so carcinoma
     stomach is more common in
     people with group 'A'. 

That's it :-p

Secretomotor pathway to submandibular gland mnemonic

This was asked on the study group - Any mnemonic for secretomotor pathway to submandibular gland?

Superior salivatory nucleus (pons)-nervus intermedius - facial nerve -geniculate ganglion - chorda tympani branch - joins with lingual nerve -submandibular ganglion -submandibular gland

So I made a mnemonic (:

"SSNIF GCT LinGG"

SS - Superior Salivatory nucleus
NI - Nervus Intermedius
F - Facial nerve
G - Geniculate ganglion
CT - Chorda Tympani
Lin - Lingual nerve
G - submandibular Ganglion
G - submandibular Gland

That's all!

Diagnosis of Infective Endocarditis ( Duke's Criteria )

Hello Everyone!

Today, I read about a case of Infective Endocarditis, and it came up with something interesting! A definite way to diagnose a typical case of IE is by Modified Duke's Criteria -

》MAJOR CRITERIA :
           
           1. Positive blood cultures
                         ○ Typical organisms in Two blood cultures
                         ○ Persistent positive blood cultures taken >12 hours apart
                         ○ Three or more positive cultures taken over more than 1 hour
         
           2. Endocardial involvement
                         ○ Positive echocardiographic findings of vegetations
                         ○ New valvular regurgitation

》MINOR CRITERIA :
( Priya Found Emban In the BalCony. )
         
         1. Predisposing factors (any cardiac abnormality, hypertension, valvular defect, congenital heart disease, i.v. drug abuse)
          2. Fever >38°C
          3. Embolic phenomenon (Embolus formation in Lungs, Brain, Spleen)
          4. Immunological phenomenon (Vasculitis, Glomerular Nephritis)
          5. Blood Cultures positive - organisms grown but not fulfilling major criteria.
         
For definitive IE, the simple rule is
2-0
1-3
0-5

☆ 2 major and No minor criteria (2-0)
☆ 1 major and 3 minor criteria (1-3)
☆ No major and 5 minor criteria (0-5)

That's all!
Thanks :)

Mechanism of action of Everolimus in breast cancer

Hello!

Did you guys know that everolimus, an immunosuppressant, is used for cancers like renal cell carcinoma, pancreatic neuroendocrine tumors, etc?

The mechanism of action is really cool, especially in ER (Estrogen receptor) +ve, HER2 -ve breast cancers.

Sometimes ER +ve tumors develop resistance to endocrine treatment such as aromatase inhibitors.

The mechanism of endocrine resistance is mainly driven by aberrant signaling along the phosphoinositide 3-kinase (PI3K) - Akt - mammalian target of rapamycin (mTOR) signaling pathway. mTOR is a Ser/Thr protein kinase that constitutes a central downstream part of this intracellular signaling pathway. Its activation enhances cell growth, proliferation and metabolism, and promotes angiogenesis. The inhibition of the mTOR pathway by targeted therapies, such as everolimus or temsirolimus, can therefore block tumor growth and induce apoptosis.

Isn't that awesome?

ACE Inhibitors in Diabetic Nephropathy

Whats the role of ACE inhibitors in diabetic nephropathy?
I was asked this question in viva..

》ACE Inhibitors retard the progression of Diabetic Nephropathy.
Here is the mechanism-

Renin-Angiotensin system (RAS) gets activated in Diabetes (both type 1 and 2). So there is increased production of Angiotensin and its products, which leads to various vascular and metabolic changes.
Angiotensin-II induces several fibrogenic chemokines, viz.
Monocyte Chemo attractant Protein-1 (MCP-1) and Transforming Growth Factor- beta (TGF-B)
AT-II activates transcription factors
Nuclear factor-KB and thus synthesis of MCP-1 in renal cells. MCP-1 has a role in monocyte immigration which transmigrates through vascular endothelium and gets differentiated to macrophages. This leads to increased Extracellular Matrix production and Tubulo Interstitial Fibrosis.

Slow acting drugs like Lisinopril, Enalapril, Ramipril are employed for 12 months therapy in Diabetic Nephropathy. Assessment of proteinuria, creatinine clearance, uMCP-1 is done before and after this period.
A decrease in protein content in urine, increase in creatinine clearance, and a massive decrease in urinary MCP-1 levels are seen.

Angiotensin Receptor Blockers also retard the renal damage in type 1 and type 2 diabetes.

That's all!
Thanks :)

Of reservation, proving yourself and deserving things

"Hello IkaN,

First of all I'd like to tell you how amazing your blog is and how glad I am to have found it.

I am in first year at a government medical college. But I don't deserve to be there. I have reservation (Yes, THAT hated word). I am also well aware that I probably took this seat from someone who scored more than me. The feeling of being less first hit me in the first month of college, when I saw a lot of people speaking out against reservation. 

I wanted to be a doctor. But not like this. The self loathing got so much so that I considered dropping out but I couldn't ask my parents to pay the bond just because I got exactly what I wanted just not in the way I wanted. Nobody in college is as such discriminating towards me but I know they feel a bit differently if they knew how I got here. 

It hinders my studies. I don't feel the same amount of interest in becoming a doctor as I did before. My parents want me to study well, even get a post graduate degree but I can't bear the thought of living all my life in the shadow of reservation.  

I don't want to sound ungrateful for the opportunity I have been given. Being a doctor is a prestige few people get and I know I'm lucky to have got it. I just wish it would have been differently. Which is why I wanted to apply for USMLE.. At least there, things would be fair. If I got something I would know it was because I deserved it. But then I wonder if I couldn't even get an undergraduate seat by myself how would I manage a post graduate one especially one in America ?

I'm not poor but neither am I rich. I don't know how much the exam fees and the books required to study for the exam cost but I'm pretty sure it is not cheap. And if after giving the exam I fail, what would I do?

I really hope you reply but I would understand if you can't because of time constraints or because you don't want to. Thank you for your time either ways."
