How HIV Causes Disease
How HIV Causes Disease samer kareem 13,689 Views • 3 years ago

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.

Trichinellosis
Trichinellosis samer kareem 5,533 Views • 3 years ago

Trichinosis (trik-ih-NO-sis), sometimes called trichinellosis (trik-ih-nuh-LOW-sis), is a type of roundworm infection. Roundworm parasites use a host body to live and reproduce. Occurring primarily among meat-eating animals (carnivores) — especially bears, foxes and walruses — the infection is acquired by eating roundworm larvae in raw or undercooked meat. When humans eat undercooked meat containing trichinella larvae, the larvae mature into adult worms in the intestine over several weeks. The adult worms then produce larvae that travel through various tissues, including muscle. Trichinosis is most widespread in rural areas throughout the world. Trichinosis can be treated with medication, though it's not always necessary. It's also easy to prevent.

LSD is one of the most potent, mood-changing chemicals. It is manufactured from lysergic acid, which is found in the ergot fungus that grows on rye and other grains. It is produced in crystal form in illegal laboratories, mainly in the United States. These crystals are converted to a liquid for distribution. It is odorless, colorless, and has a slightly bitter taste.

People with celiac disease may lose weight because their bodies are not able to absorb enough nutrients from food. Over time, a range of problems may develop as a result of the body's reaction to gluten — from skin rashes and lactose intolerance to infertility, bone weakness and nerve damage.

What is Thalassemia
What is Thalassemia samer kareem 1,740 Views • 3 years ago

Thalassemia is a genetic blood disorder. People with Thalassemia disease are not able to make enough hemoglobin, which causes severe anemia. Hemoglobin is found in red blood cells and carries oxygen to all parts of the body. When there is not enough hemoglobin in the red blood cells, oxygen cannot get to all parts of the body. Organs then become starved for oxygen and are unable to function properly.

Treatment of Pneumothorax samer kareem 2,803 Views • 3 years ago

A pneumothorax (noo-moe-THOR-aks) is a collapsed lung. A pneumothorax occurs when air leaks into the space between your lung and chest wall. This air pushes on the outside of your lung and makes it collapse. In most cases, only a portion of the lung collapses.

Hemothorax

hemothorax is most often defined as rapid accumulation of ≥ 1000 mL of blood. Shock is common. Patients with large hemorrhage volume are often dyspneic and have decreased breath sounds and dullness to percussion (often difficult to appreciate during initial evaluation of patients with multiple injuries).

Dementia Signs and Symptoms
Dementia Signs and Symptoms samer kareem 1,272 Views • 3 years ago

Dementia is not a specific disease. It's an overall term that describes a wide range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person's ability to perform everyday activities. Alzheimer's disease accounts for 60 to 80 percent of cases. Vascular dementia, which occurs after a stroke, is the second most common dementia type. But there are many other conditions that can cause symptoms of dementia, including some that are reversible, such as thyroid problems and vitamin deficiencies.

Bovine Respiratory Disease
Bovine Respiratory Disease samer kareem 1,284 Views • 3 years ago

Bovine respiratory disease (BRD) has a multifactorial etiology and develops as a result of complex interactions between environmental factors, host factors, and pathogens. Environmental factors (eg, weaning, transport, commingling, crowding, inclement weather, dust, and inadequate ventilation) serve as stressors that adversely affect the immune and nonimmune defense mechanisms of the host. In addition, certain environmental factors (eg, crowding and inadequate ventilation) can enhance the transmission of infectious agents among animals. Many infectious agents have been associated with BRD. An initial pathogen (eg, a virus) may alter the animal’s defense mechanisms, allowing colonization of the lower respiratory tract by bacteria.
