Blood Transfusion-Transmitted Diseases

CD4 T-cells (a type of white blood cell) are important to your body's defence against infections. This animation describes how your immune system is weakened by the HIV virus, which targets CD4 T-cells and leads to their gradual decline in number. Low to very low levels of CD4 cells put you at risk for 'opportunistic infections' that take advantage of the body's weakened immune system.

This is a Video in Clinical Medicine from the New England Journal of Medicine. Tympanocentesis in Children with Acute Otitis Media Overview Tympanocentesis is defined as needle aspiration of fluid from the middle ear.

TransMedics’ proprietary Organ Care System (OCS) is the first commercial and portable warm blood perfusion organ transport system. With the OCS, doctors are able to perform “living organ transplants,” where organs are kept warm and functioning in a controlled environment from the time they are recovered to the moment they are placed in the recipient’s body.

Angina results from a reduction in the oxygen supply/demand ratio. Therefore, in order to alleviate the pain, it is necessary to improve this ratio. This can be done either by increasing blood flow (which increases oxygen delivery or supply), or by decreasing oxygen demand (i.e., by decreasing myocardial oxygen consumption).

Surgery is an elective procedure done in people who have had extensive testing to decide if they are potential candidates. The following criteria are considered when determining if a person may be a good candidate for surgery. Person has failed adequate trials of two first-line seizure medicines (ones that are commonly effective in controlling the type of seizures the person is experiencing) and one combination of at least two drugs. A trial of a medication is considered adequate when it has been increased gradually to the maximum dosage that does not cause serious side effects. If the person has frequent seizures, any improvement will be obvious after a short time. If the seizures generally occur far apart, however, it may take months to determine whether a medication is helping. At some epilepsy centers, patients are offered additional conventional or experimental medications before surgery is considered. But research suggests that each time a trial of medication fails to control a person's seizures, it becomes less likely that a different medicine or combination will be successful. Since uncontrolled seizures present serious physical risks and social and psychological consequences, the trend these days is to proceed with surgery much sooner than in the past if it seems appropriate for that person.

Diuretics, sometimes called water pills, help rid your body of salt (sodium) and water. Most work by making your kidneys release more sodium into your urine. The sodium then takes water with it from your blood. That decreases the amount of fluid flowing through your blood vessels, which reduces pressure on your vessel walls.
