IHS diagnostic criteria for Migraine


In 1988 the International Headache Society published criteria for the diagnosis of a number of different headache types . Those for some of the common headaches are reproduced below for migraine with and without aura, cluster headache, tension-type headache, and cervicogenic headache.

11 Health Benefits of Pomegranate Juice~


1)Fights Breast Cancer

Studies in Israel show that pomegranate juice destroys breast cancer cells while leaving healthy cells alone. It may also prevent breast cancer cells from forming.

2) Lung Cancer Prevention
Studies in mice show that pomegranate juice may inhibit the development of lung cancer.

3) Slows Prostate Cancer
It slowed the growth of prostate cancer in mice.

4) Keeps PSA Levels Stable
In a study of 50 men who had undergone treatment for prostate cancer, 8 ounces of pomegranate juice per day kept PSA levels stable, reducing the need for further treatment

5) Protects the Neonatal Brain
Studies show that maternal consumption of pomegranate juice may protect the neonatal brain from damage after injury.

6) Prevention of Osteoarthritis
Several studies indicate that pomegranate juice may prevent cartilage deterioration.

7) Protects the Arteries
It prevents plaque from building up in the arteries and may reverse previous plaque buildup.

8) Alzheimer's Disease Prevention It may prevent and slow Alzheimer's disease. In one study, mice bred to develop Alzheimer's disease were given pomegranate juice. They accumulated significantly less amyloid plaque than control mice and they performed mental tasks better.

9)Lowers Cholesterol
It lowers LDL (bad cholesterol) and raises HDL (good cholesterol).

10) Lowers Blood Pressure
One study showed that drinking 1.7 ounces of pomegranate juice per day lowered systolic blood pressure by as much as 5 percent.

11) Dental Protection
Research suggests that drinking pomegranate juice may be a natural way to prevent dental plaque.

ECG CHANGES IN CHAMBER HYPERTROPHIES/ENLARGEMENTS


CHAMBER HYPERTROPHIES/ENLARGEMENTS ::

LEFT ATRIAL ENLARGEMENT
-- Left atrium forms the later part of the P wave. Hence enlargement of left atrium will produce an increase in the duration of the P wave, as well as delayed depolarization leading to "Double peaks" in P wave
-- Also called " P - mitrale "
-- This is evident very clearly in Chest leads 
-- P wave is generally > 120 ms
Image : LAE ... typical "bipeaked " P mitrale
 







RIGHT ATRIAL ENLARGEMENT

-- Right atrium forms the initial part of the p wave... hence Right atrial enlargement will produce Peaked/Tall P wave, and not widen the duration of P wave.
-- Refered to as P - pulmonale
-- Tall peaked P wave is seen in lead II and many leads (especially in right precordial leads) 
-- P wave is Pointed
-- Usually > 2.5 mm

Normal CT Scan:

Normal CT Scan:

It is worth spending a few minutes familiarising yourself with the appearances of a normal CT scan. It is much easier to detect abnormalities once you are accustomed to normal appearances. The scan below is a slice through the human brain and you should imagine that you are viewing it as if looking up from the patient's feet. Therefore, the patient's left is to the right of the screen. The shape of the ventricles is quite distinctive and they are shown outlined in green and orange. The presence of the third ventricle in the midline is one of the first things to look for. If the third ventricle is either not visible, or shows signs of shift away from the midline, this suggests that there is an abnormality. The basal cisterns is the fluid filled space around the back of the midbrain outlined here in purple. Blood clots, or swelling of the brain may cause this to become narrowed, or not visible altogether. Note in this scan, that the frontal horns of the lateral ventricles are symmetrical, with the septum between them in the midline.
