A large glass of wine a day increases the risk of liver and bowel cancer by a fifth, experts have warned. What’s more, the same goes for a pint of beer or a couple of spirits such as vodka or gin.
Rachel Thompson, science programme manager for World Cancer Research Fund (WCRF), warned that just two units of alcohol a day increases the risk of bowel cancer by 18 percent and the risk of liver cancer by 20 percent. [Read more...]
It is constituted by much larger vascular spaces which are lined by a single layer of endothelial cells. The lesions are usually present at birth and do not show any significant increase in size later. Clinically, they consist of red or bluish red irregular, lobulated masses which may be situated on any part of the body.
Surface lesions may manifest as reddish or bluish vesicles when situated near the eye or on the tongue, they may cause pressure symptoms and interfere with the function of the part. When situated on the pressure points such as the knee or the elbow, they may get easily traumatized and result in profuse bleeding. [Read more...]
Offering yet another reason to never start smoking, a new study finds that both current and former smokers run an elevated risk of the heart rhythm disorder atrial fibrillation.
The condition, also known as AF, is the most common heart arrhythmia in the United States, affecting about 2 million people. During an episode of AF, abnormal electrical activity in the heart causes its upper two chambers to beat in a rapid, uncoordinated rhythm; the arrhythmia itself is not life-threatening, but over time AF can contribute to stroke or heart failure in some people.
While smoking is a well-known risk factor for heart disease, it has not been clear whether the habit boosts the risk of AF specially.
The new findings, reported in the American Heart Journal, suggest that it does even after a smoker quits. [Read more...]
It is a type of congenital arteriovenous fistula. There is pulsatile swelling of arteries and the veins become arterialized i.e. tortuous and thick walled and pulsatile-feeling like a bag of pulsating earthworms. This is often called cirsoid aneurysm. Such cirsoid aneurysm is commonly seen on the forehead or in the scalp over the temporal region.
Characteristic features
It consists of multiple dilated venous channels. It is a spongy swelling.

Clothing should be removed from the arm. If it cannot be removed, it is better to leave it as it is, rather than fold the clothing into tight constricting bands.
The cuff should be encircled around the arm. If the bladder of the cuff does not encircle the arm completely, the centre of the bladder should be over the brachial artery. The rubber tubes from the bladder are usually placed inferiorly at the site of the brachial artery, but it would be better to place it superiorly or posteriorly so that the antecubital fossa is easily accessible for auscultation.
The bell of the stethoscope gives better sound reproduction but a diaphragm is easier to secure with the finger of one’s hand and covers a large area.
To measure BP in the legs a thigh cuff containing a large bladder (18 x 24 cms) for adults should be wrapped around the thigh of the prone patient and the Korotkoff sounds auscultated in the popliteal fossa in the usual way.
BP in the legs is equal to that in the arms provided the bladder is adequate in size.
Sunscreens are the agents which protect the skin from sunlight. Two types of agents: (1) reflectors, and (2) absorbers, can act as sunscreens. Reflectors are substances which when present on the skin surface reflect the rays of light in other directions and thus, prevent them from entering the skin.
These are active against all wavelengths of sunlight. Absorbers, on the other hand, absorb the sunlight and therefore, these are active against only a specific spectrum of sunlight. The following agents can be used alone or in combination with each other to act as sunscreens, but it is important to remember that sunscreens need to be applied only as long as there is daylight, it is no use applying sunscreens at night.

MicroBridge Services, based at Cardiff University, south Wales, is pioneering work in which tiny implants would be able to effectively channel brain-waves to prosthetic limbs. The company is a leader in micro-engineering design and manufacture and possibly the only firm in the world capable of creating the implants.
The implants are the size of a match head carrying 100 sensors made of extremely hard tungsten carbide, which conducts electricity. Only slightly thicker than a human hair, the sensors sit on the brain picking up nerve impulses and send them to prosthetic limbs. The scientists are expecting that the technology may eventually help amputees to learn to move prosthetic limbs and regain lost mobility. [Read more...]
Tiny sacs released from tumor cells and circulating in the blood carry genetic information about the tumor, offering a new way to track and treat the cancer, US researchers said on Sunday. “They contain a little piece of the tumor cell in the blood stream.
If you just look at these packets, you basically know what kind of mutations are in the tumor cell,” said Xandra Breakefield of Massachusetts General Hospital in Boston, whose study appears in the Journal Nature Cell Biology.
These membrane covered packets, called exosomes, represent a new way of getting information about a cancer, offering a means of choosing the best therapy, seeing how a patient responds to treatment, and possibly offering a way to deliver therapies back to the tumor, Breakefield said.
