The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin (oedema). It usually begins in the legs but can involve the whole body, including the face.

Sleeping sickness is also known as African trypanosomiasis.

Dependency age groups are 14 years and younger and 65 years and above.

The dependency ratio is a measure of the number of dependents aged zero to 14 and over the age of 65, compared with the total population aged 15 to 64. This demographic indicator gives insight into the number of people of non-working age, compared with the number of those of working age.

Rupture of an aneurysm is a life-threatening emergency and is of the greatest concern for the nurse caring for this type of person. The layers of the aortic wall can also separate (aortic dissection). This produces severe, tearing pain in the chest, back or abdomen. The potential for rupture is the most serious risk associated with an aortic aneurysm. A ruptured aortic aneurysm can cause life-threatening internal bleeding and/or a stroke.

Resistivity of semiconductors decreases with a increase of temperature.

​Variation of resistance with temperature:

• Semiconductors like Silicon and Germanium contains lesser charges than those of metals but has more charges than insulators. These charge carriers are generated by the thermal breaking of bonds.
• Thus, as the temperature rises, more covalent bonds break, releasing more electrons and the number of electrons and holes will increase which lowers the resistivity rapidly.

Polio is a viral disease.

• Bahutrisha, also often referred to as polio or 'poliomyelitis', is a viral infectious disease that is usually transmitted from person to person through infected feces or food.

The signs and symptoms of intracranial pressure include Hypertension and bradycardia. Increased intracranial pressure can result from bleeding in the brain, a tumor, stroke, aneurysm, high blood pressure, or brain infection. Treatment focuses on lowering increased intracranial pressure around the brain. Increased intracranial pressure has serious complications, including long-term (permanent) brain damage and death.

Troponin I is extremely specific for the cardiac muscle and has not been isolated from the skeletal muscle. This absolute specificity makes it an ideal marker of myocardial injury. They are released into the circulation 6–8 h after myocardial injury, peak at 12–24 h and remain elevated for 7–10 days.
