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. In children with acute otitis media, drainage of pus from the middle ear results in a rapid and marked improvement in symptoms and enables the clinician to prescribe tailored antimicrobial therapy. This video will demonstrate the technique of tympanocentesis. Indications Tympanocentesis is recommended in children with refractory acute otitis media, in immunocompromised children with otitis media, and in children with suppurative complications of acute otitis media, . . . .
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.
Overbite is a type or malocclusion or an overjet. A lot of people don’t realize that they have an overbite, as they believe their condition is not serious enough to obtain dental attention. This could also for the reason that other cases of overbites are so minor to be noticeable. However, others have serious overbite condition that can make the person’s top jaw look much larger or the bottom jaw significantly smaller. But one thing to remember, overbite can actually cause some dental problems. This condition can change the structure of your face and affect the way you talk. The most popular form of overbite correction is orthodontic treatment. Your dentist will fix the overbite with the help of rubber bands and dental braces to pull the upper teeth back. Tooth extraction may be suggested if overcrowding complicates the overbite so as to provide room for your front teeth. In extreme conditions, overbite surgery may be needed to place your jaw backwards or forwards. Furthermore, if severe overbite is not corrected during adulthood, the teeth may continue to shift and trigger dental issues such as gum disease.

The cause of pectus excavatum is not known however it can run in families, with up to 25 percent of affected patients reporting chest wall abnormalities in other family members. Pectus excavatum occurs in approximately 1 out of 400–1000 children and is three to five times more common in males than females.
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.
Hypertrophic pyloric stenosis (HPS) causes a functional gastric outlet obstruction as a result of hypertrophy and hyperplasia of the muscular layers of the pylorus. In infants, HPS is the most common cause of gastric outlet obstruction and the most common surgical cause of vomiting.
A good starting point for any scientist in any field is to recognize that there is much we do not know. We do not know, for example, why there is more matter than antimatter in the universe. We do not know very well how the evolution of the dinosaurs filtered out. And, perhaps most surprising of all is that we do not know very well how many organs the human body has or what all its functions are.
