Health and Medical Care Tips
This nevus is also called epidermal nevus, ichthyosis hystrix or nevus unius lateralis and is formed by excessive proliferation of the epidermal cells. Most of the lesions are present at birth, but some lesions may appear later also.
These occur in the form of asymptomatic hyperkeratotic, verrucous areas which may appear in a localized area or may be arranged either in a linear fashion or in irregular bizarre shapes, which may cover large areas on the body. [Read more...]
This nevus consists of an irregular area of hypopigmentation which tends to have a unilateral distribution. The lesion is present at birth and remains unchanged throughout life. It is produced by an abnormally exaggerated tendency of the cutaneous capillaries for vaso-constriction or constriction of blood vessels.
Whenever this area is massaged with the hand, the lesion fails to develop erythema which appears in the adjoining normal skin. Pressure with a glass slide also makes the lesion disappear and indistinct from the surrounding skin. [Read more...]
Strategy-based videogames can enhance reasoning, memory and other cognitive abilities that often decline with age.
In a study of 40 adults in their 60s and 70s, researchers found that those who learned to play a strategy-heavy videogames improved their scores of tests of cognitive function. Men and women who trained in the game for about a month showed gains in tests of memory, reasoning and the ability to “multi-task”.
The findings suggest that videogames that keep players “on their toes” might help older adults keep their brains sharp, the researchers report in the journal Psychology and Aging. [Read more...]
It is also called strawberry haemangioma and is made up of immature blood vessels which are lined by several layers of endothelial cells. It is usually not present when the child is born but appears during the first few months of life.
Thereafter, it steadily increases in size and continues to grow till the child is between two and five years of age. After that, the lesion starts involuting and in most of the instances, the involution is complete without leaving any mark. [Read more...]
Research on mice has shown that common food additives known as phosphates may help lung cancer tumors grow faster, at least in mice. The research has been conducted in South Korea. Phosphates are additives-found in many soft drinks, baked goods, processed meats and cheese.
A diet that is high in phosphates significantly increased the lung surface tumor lesions as well as the size.
The research suggests that cutting back on inorganic phosphates “may be critical for lung cancer treatment as well as prevention”.
Phosphates are critical to human nutrition and can be used in compounds that enrich calcium and iron content and prevent food from drying out. But Cho said it is possible that some people get too much. [Read more...]
For local application of drugs, the active ingredients have to be dissolved or suspended in a vehicle substance called a base. The main function of the base is to keep the active ingredients in contact with the lesion.
The selection of a base is made depending upon the type and the site of the lesions to be treated and also the solubilities and the reactivities of the active ingredients with the base.
The following bases are commonly used in preparation of medicine for skin condtions:
Water: Sterilized water is a good base for making soothing applications, astringents and anti-infective agents containing dyes. It is an ideal base for treating exuding lesions or those present in the skin folds, because water evaporates easily from the surface, elaving the active ingredients to have their effect on the skin lesion.

Bad posture can lead to multitude of problems, not only in the back but other regions of body also. If you have a habit of maintaining a bad posture, use following tips to improve your posture
Medicines employed for promoting desquamation of the scales or thickened stratum corneum are called keratolytic agents.
These are required for the treatment of a large number of diseases such as ichthyosiform dermatoses, palmo-plantar keratodermas, corns, psoriasis and lichenified dermatoses.
These drugs should be avoided in lesions associated with acute or subacute inflammation. The drugs commonly employed for this purpose include the following: [Read more...]
A breakthrough in brain and spinal cord repair is expected. Damaged nerve cells in the brains of mice may be made to repair themselves by turning off proteins that keep nerve cells growth in check.
This is the first time it has been possible to see such significant regeneration by manipulating single molecules.
The research team focused on a gene network called the mTOR pathway, which is active when young nerve cells are first growing but becomes less so once they mature.
Nerve injury appears to shut down this network completely.
And two proteins PTEN and TSCI-appear to be responsible for silencing this pathway.
When these proteins are blocked, the cells show capability of repair.
Dieting during winters could impair the body’s immune system and make people more susceptible to the flu virus, experts have found.
Mice who were put on a calorie-controlled diet found it harder to tackle the infection than those on a normal diet, BBC News website reported on Friday.
The findings suggest that contrary to the old adage “starve a fever”, those with a temperature should eat well. Flue cases in England and Wales aer currently approaching a nine year high.
The team at Michigan State University found even though the mice on the lower calorie diet received adequate amounts of vitamins and minerals, their bodies were still not able to produce the amount of killer cells needed to fight an infection.
As well as being more likely to die from the virus, the mice-which were consuming around 40 percent of the calories given to their counterparts on a normal diet-took longer to recover, lost more weight and displayed other symptoms of poor health.
“Our research shows that having a body ready to fight a virus will lead to a faster recovery ad less severe effects than if it is calorically restricted,” said study lead author Elizabeth Gardner.
“IF the strain of flu a person is infected with is different from the strain included in the flu vaccination, then your body sees this as a primary infection and must produce the antibodies to fight it off,” Gardner said.
The study, the team added, should not be seen as a carte blanche to avoid dieting all year, but to reserve weight control to the eight months of the year when flu is not so virulent.
