Parkinson’s disease in question

Discovered in 1817 by a British physician who gave him his name, Parkinson’s disease affects 4 million people in the world. Of the 100 000 a 150 000 probable PD, only 80,000 are known and followed. Too often slow and earthquakes are attributed to the simple fact of aging.

Each year, 8,000 new cases. Although the disease usually starts between 55 and 65 years, 5 to 10% of patients have at much younger ages (between 30 and 55 years).


What is Parkinson’s disease?
Discovered in 1817, Parkinson’s disease is still far from having revealed all its secrets. Nervous system, its cause is still unknown. The disease is characterized by the disappearance of a small number of nerve cells (neurons) that secrete a neurotransmitter called dopamine involved in the proper functioning of many parts of the brain and essential for cell survival.Connection between two neurons.

Why men don’t listen to half?

It might be a scientific justification for the scant attention which men are capable. Researchers at Indiana University (United States) found the explanation to this ancestral problem: men seek only half of their brains when they listen while women use the two cerebral hemispheres.This is a study that could well feed conversations and revive a war of the sexes.

Rather than a lobe or an ear…
Equipped with headphones, twenty men and twenty women took attention to the reading of a passage from a novel by John Grisham. During this period, and under the eye a MRI (magnetic resonance imaging) scanner happening their brains examined, the majority of the men showed brain activity of one temporal lobe of the left hemisphere, generally associated with the functions of listening and language. Conversely, the brain of the majority of the women testified to an activity in the temporal lobe of the two hemispheres, both the left than the right, commonly used for musical activities and the situation in the area.

Why men don't listen to half

The areas of brain activity in red highlight that men use a lobe to listen to two women.
The study presented at the annual meeting of the society of Radiology in North America in Chicago does not, however, if men have a capacity of less than women listen. “Our research suggests that the way to listen differs between the sexes, but this does not necessarily imply that the capacity and performance go hand in hand,” says Professor Joseph Lurito, responsible for the study.

Cardiac arrest

The heart is a hollow pear shaped muscular organ located between the lungs. It ensures the circulation of the blood in the body, allowing the cells to receive oxygen and nutrients. This movement is essential to life. Heart failure causes the death of the victim in the short term. React!

In a cardiac arrestif no gesture of relief is realized immediately, and if relief did not occur, the victim’s life is threatened in the short term. Any victim must have an external heart massage associated with artificial ventilation so that its survival is maintained pending the arrival of relief. The recommendations come from change recently. They are specified by PR. Pierre Carli, Chief of the Samu de Paris and president of the French Council of cardiopulmonary resuscitation (CFRC).

Cardiac arrest

How to react?
The new recommendations focus on the simplification of the gestures: resuscitation, there is no time to lose because every minute is counted and paid by a loss of chance of survival. “The new recommendations do plus all the distinctions of situation (adult/children) taught previously. In the absence of signs of life, began cardiopulmonary resuscitation without asking any question, on the basis of 30 chest compressions to 2 breaths”said Pr Pierre Carli.
First case: the victim complains of a pain in the chest. Continue reading “Cardiac arrest”

Is cancer related to food?

Cancer is the second cause of mortality in France. The most common are those of the breast, colon, prostate and lung. Food is a major factor in the emergence and the development of this disease.

Cancer is almost always the result of several factors, including food, whose role is better known. Food can promote the development of cancer in several ways: toxicity of certain food contaminants, possible carcinogenic role of some food additives, and especially composition of the diet with the presence too high or too low of some nutrients.


Contamination by a fungus

An example of contamination of food by a carcinogenic risk for liver substance is the presence of antitoxin: this microscopic fungus can persist in peanuts and some cereals in tropical climate is subject to extremely strict control. Continue reading “Is cancer related to food?”

Diet and cardiovascular disease

In France, cardiovascular problems are responsible for a third of the deaths. It is the leading cause of death in women and the second cause for men. However these death rates are the lowest in the European Union for reasons still not known. The food is certainly not foreign. It indeed plays a key role in the appearance of these cardiovascular problems.

Among the causes of cardiovascular diseases, the most important is atherosclerosis, degenerative phenomenon that reached the arteries by reducing their elasticity and creating a decrease, or a decision of the arterial flow.

cardiovascular disease

Many factors involved

This pathology that covers several diseases (ischemic heart disease, cardiovascular disease etc.) is the responsibility of multiple factors: genetic, nutritional, obesity, physical inactivity, tobacco, high blood pressure, diabetes. Among these causes, dietary factors have a very important place and their role in cardiovascular pathology is the subject of multiple research for 50 years to better prevent and control these diseases.

Dental caries and diet

Once, the sugar was considered an exceptional food and was reserved for the sick or consumed during the holiday season. It became a food consumed every day since the development of the industrial production of sugar, he y a century. For a long time, dental caries was that adults, and she began to reach children in parallel to the development of the sugar industry.

Today it is a disease that affects mostly children, adolescents and young adults; its frequency decreases after 40 years. It is a public health problem that has a very significant cost. In France, at the age of 6 years, two thirds of the children already have at least a decay.

Dental caries

Sugar and carie good household

Carie detainment et sentimentalization is a phenomenon of demoralization of the hard tissues of the tooth (enamel, dentin, cementum), caused by the acidic environment created sugars made by food and certain bacteria in dental plaque. Sugar consumption is therefore a key element of the formation of caries. The sugars the most “cariogenic” are fast sugars, including sucrose, main component of sugar cane and sugar beet. It is the most used in confectionery. Then came the (industrially produced from corn, used in baking) glucose, fructose (fruit sugar), lactose (milk sugar) and starch (slow sugar grains and starches), which is much less cariogenic.

Men, women uneven before depression

At the time of parity, equality of the sexes… of American researchers tried whether the events promoting depression were the same for men and women. Results: if women are more sensitive to the problems of their family circle, men appear to be more difficulties to live a separation or professional difficulties.

All latitudes, women are more prone to depression than men. A factor that intrigues long specialists and remains poorly understood. Is the second sex life more difficult? What is the role of the social environment?

Men, women

To answer these questions, the team of Dr. Kenneth s. Lender studied for ten years, in the Department of Psychiatry at the Medical College of Virginia and the Institute of Psychiatry and behavioral genetics of Richmond, 5,000 pairs of variable sex twins born between 1934 and 1974. For this purpose, these twins were interviewed four times by professionals during this decade of investigation. Continue reading “Men, women uneven before depression”


here are two types of bone cancer: primary cancer of the bone, rare, and secondary bone cancer or bone metastases, more frequent.

-Primary cancer of the bone
-Ewing’s sarcoma
-Multiple my Loma
-The role of surgery


Primary cancer of the bone

Primary cancers of the bones are localized cancers in the bone, or its immediate periphery, which develop from bone, cartilage or fibrous. They are quite rare. The main ones are osteosarcoma, chondrosarcoma, the Ewing’s sarcoma and multiple myeloma . The secondary bone cancer , or bone metastases, are remote locations, in bone cancer in another organ: prostate , kidney, breast, thyroid, … Continue reading “BONE CANCER: KNOW EVERYTHING”


Lumbago, sciatic, herniated disc, as many pathologies of the spine (called rachis again) become a Calvary for those who suffer from. Often presented as a solution of last resort, surgery of the spine allows today, through new technologies, alleviate the evil of the century.

-Back pain: who and when operates t – on?
-Between classic surgery and new surgery
-Operations of the back more “gentle”.
-Changing back surgery
-Back surgery: a miracle solution?
-Back pain: prevention and awareness
-Lumbago, backache, sciatique…, how to distinguish them?


“I had the feeling to be released”.
“I have full back ! This exclamation was not found by chance. The back is indeed one that bears the weight of pain, physical or psychological. In France they are about three million people who suffer back. Many people who have tried the physiotherapists and osteopaths, the disqualification and pomades relaxing without find outcome to this evil which range daily and sometimes becomes a real handicap social and professional. If all patients cannot be candidate for back surgery, for some diseases, it is very effective. With new technologies that today enjoys this surgery operations become less invasive and more in more rapid convalescence. Continue reading “THE BACK SURGERY, CHANGING”
