Skin cancer mnemonics

Here are some memory aids that I use :)

Fact of the day: Cocaine addiction and iron concentration in brain

Do you know? Cocaine addiction leads to increased concentration of iron in globus pallidus. The more one takes this drug, more amounts of iron get accumulated in this region of brain, which normally acts as a 'brake' for inhibiting behaviour.

Also, the increased concentration of iron in brain is accompanied by iron deficiency in rest of the body.

This is possibly attained by decreasing absorption of iron from food and increasing permeability of blood- brain barrier.

Long QT Syndrome

Hey guys this post will be on Long QT syndrome as evident from the title :P.

In a brief introduction, it can be said that LQTS is simply because of abnormal myocardial repolarization most often due to a mutation in ion channel-associated gene. It can lead to fatal ventricular arrhythmias such as torsades de pointes.
So there is increased risk of Sudden Cardiac Death.

It has 3 common variants:

1. LQT1: Loss of function mutation in KCNQ1 gene. And in ECG you see early-onset broad-based T wave.

2. LQT2: Mutation in KCNH2 gene. In ECG T waves are of low amplitude, broad based and maybe bifid.

3. LQT3: Mutation in SCN5A gene. In ECG, there is prolonged ST segment with late-appearing T wave.

We use the ECG to diagnose LQTS and we estimate the probability by using Schwartz score.
Some of the important criteria are :-

1. QTc more than 480msec
2. T wave alternans (Varying amplitudes)
3. Torsades de pointes
4. Notched T waves in atleast 3 leads
5. Syncopal attacks with and without stress
6. Congenital deafness
7. Significant family history
