Cerebral Palsy

-
Cerebral Palsy, a range of neuromuscular disorders caused by injury to an infant's brain sustained during late pregnancy, birth, or any time during the first two years of life. People with cerebral palsy have a wide range of difficulties, from a clumsy walk to an inability to speak or swallow, caused by faulty messages sent from the brain to the muscles. In the mid-1800s, William Little, an English physician, first described cerebral palsy in connection with birth injuries.

CAUSES

Advances in diagnostic technology have led to a much better understanding of the causes of cerebral palsy. Over half of the cases are now thought to be due to prenatal causes such as an infection that spreads from the mother to the fetus, maternal stroke that prevents proper blood supply to the fetus, exposure to environmental toxins, or problems in brain development.

The remaining cases are due to adverse events such as traumatic birth delivery, premature birth and its complications, meningitis (infection of the brain or its protective coverings), or head injury due to child abuse. Very rarely, heredity plays a role. In some cases, it is difficult to pinpoint a single event that may have caused cerebral palsy.

TREATMENT AND PREVENTION

Injury to the brain in individuals with cerebral palsy is permanent, and full recovery is not possible. Damaged brain tissue does not regenerate, but to some extent, normal nerve cells and nerve pathways can take over some function from injured areas, with some limitations. The degree of severity varies so greatly from case to case that it is difficult to make a general prognosis.

Successful treatment of cerebral palsy requires input from a variety of professionals. Physicians address health issues such as poor eyesight or restrictions in joint motion. Physical and occupational therapists help the child develop skills necessary to the activities of daily living. Speech pathologists deal with swallowing and speech dysfunction. Psychologists and educators work with emotional or learning difficulties. Nutritionists ensure normal growth. These professionals and numerous others work together as a team with the child or adult to help the individual achieve as much independence and competence as possible. In addition, family involvement in treatment, especially with children, is an essential component. With therapy, training, and community support, most individuals with cerebral palsy can lead meaningful and productive lives.

Many causes of cerebral palsy are preventable, especially those that occur at or after birth. Good prenatal care has been shown to minimize the likelihood of premature birth; new vaccines against Hemophilus influenzae have reduced the incidence of meningitis; and family support programs have reduced the number of cases of severe child abuse. Such preventive measures are cost-effective in that they reduce the expense of supporting individuals with cerebral palsy.

Cream, Butter, and Ice Cream

-
. In order for a product to be labeled as cream, it must contain 18 percent milk fat or more. Light whipping cream must contain at least 30 percent fat, and 36 percent fat is the minimum fat content for heavy whipping cream. Half-and-half, an equal mixture of both milk and cream, must have at least 10.5 percent fat. The various grades of cream are valued for their smooth, thick texture. They are often used in cooking instead of milk, because they are less likely to form a skin when heated and can be whipped into a stiff foam. When chilled cream is churned gently, the fat globules gather together to form butter, leaving buttermilk as the by-product. Butter contains at least 82.5 percent fat. In the past, before the advent of widespread refrigeration, salt was added to butter to retard bacterial spoilage; now salt is added mainly for flavor. Ice cream, a popular frozen dessert, is made of milk, cream, sugar, and flavoring. The mixture is slowly beaten while chilled until it is partially

How HIV Causes Infections

-
HIV transmission occurs when a person is exposed to body fluids infected with the virus, such as blood, semen, vaginal secretions, and breast milk. The primary modes of HIV transmission are (1) sexual relations with an infected person (see Sexually Transmitted Infections ); (2) sharing hypodermic needles or accidental pricking by a needle contaminated with infected blood; and (3) transfer of the virus from an infected mother to her baby during pregnancy, childbirth, or through breast-feeding. When HIV enters the body, it infects lymphocytes, which are a type of white blood cell in the immune system . HIV uses its glycoproteins to attach itself to receptors on the surface of a lymphocyte. The outer envelope of HIV then fuses with the lymphocyte, enabling the HIV capsid to enter the lymphocyte itself. HIV commandeers the genetic material of the lymphocyte, instructing the cell to replicate more viruses. The newly formed viruses break free from the host, destroying the cell in the process

Deoxyribonucleic Acid

-
Deoxyribonucleic Acid (DNA), genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus, passing on the information needed for protein synthesis. In most cellular organisms, DNA is organized on chromosomes located in the nucleus of the cell .
