Abscess - A localized collection of pus in a cavity formed from tissues that have been broken down by infectious bacteria. Abscesses may occur on the skin surface or within the body on such internal organs as the lungs, brain, kidneys, or tonsils.

Altitude Sickness - Also called MOUNTAIN SICKNESS, acute reaction to a change from sea level or other low-altitude environments to altitudes above 8,000 feet (2,400 m).The symptoms of altitude sickness fall into four main categories: (1) respiratory symptoms such as shortness of breath upon exertion, and deeper and more rapid breathing; (2) mental or muscular symptoms such as weakness, fatigue, dizziness, lassitude, headache, sleeplessness, decreased mental acuity, decreased muscular coordination, and impaired sight and hearing; (3) cardiac symptoms such as pain in the chest, palpitations, and irregular heartbeat; and (4) gastrointestinal symptoms such as nausea and vomiting.

Anoxia - Lack of oxygen. 

Ascites - Accumulation of fluid in the peritoneal cavity, between the membrane lining the abdominal wall and the membrane covering the abdominal organs. The most common causes are cirrhosis of the liver, heart failure, tumour invasion of the peritoneal membranes, and escape of chyle (lymph laden with emulsified fats) into the peritoneal cavity. In patients having liver disease, the onset of ascites is usually preceded by accumulation of fluid in the ankles. The abdomen is often uncomfortably distended, and muscles become wasted.

Charles Bonnet Syndrome( --> Hallucinations) - The experience of perceiving objects or events that do not have an external source. A hallucination is distinguished from an illusion, which is a misinterpretation of an actual stimulus.

Chest Pain

Death

Disease

Diverticulitis - Fecal matter may be pushed into the pouches that form in the colon and may cause them to bulge out from the colon wall. Such a condition is called diverticulosis. This condition has no symptoms, but the feces-filled sacs may become inflamed, a more serious condition called diverticulitis. Its symptoms are pain and cramps in the lower left side of the abdomen, chills, and sometimes fever.

Dyspepsia - Also called Dyspepsia, any or all of the unpleasant feelings and manifestations--abdominal discomfort, belching, flatulence, aversion to eating, nausea, vomiting, diarrhea, constipation, heartburn--that sufferers associate with the malfunctioning of their digestive apparatus.

Ecchymosis - A discoloration of the skin resulting from bleeding underneath, typically caused by bruising.

Edema - Also spelled OEDEMA OR EDEMATA, is an abnormal accumulation of watery fluid in the intercellular spaces of connective tissue. It may cause diseases of the kidneys, heart, veins, or lymphatic system; malnutrition; or allergic reactions.

Endocarditis, Bacterial - Inflammation of the heart lining, or endocardium. It may be associated with a noninfectious disease or may be caused by infection with any of a number of organisms, including bacteria and fungi.

Fever - Fever generally results from a disturbance in the regulation of body temperature by the central nervous system. 

Fibrosis - The thickening and scarring of connective tissue, usually as a result of injury.

Flatulence - The presence of excessive amounts of gas in the stomach or intestine, which sometimes results in the expulsion of the gas through the anus.

Gangrene - Localized death of animal soft tissue, caused by prolonged interruption of the blood supply that may result from injury or infection.

Granuloma

Halitosis - It is due to the rotting debris in the pockets under the gum margins. In due course the teeth loosen and fall out or need to be extracted.

Hallucinations - It may be produced by chemical changes deriving from internal metabolic disturbances that are otherwise engendered inside of the body, or that originate from outside of the body. The experience of perceiving objects or events that do not have an external source. A hallucination is distinguished from an illusion, which is a misinterpretation of an actual stimulus.

Hemoptysis -  Blood loss from lungs.

Hernia - A condition in which part of an organ is displaced and protrudes through the wall of the cavity containing it (often involving the intestine at a weak point in the abdominal wall).

Hiccup - Also spelled HICCOUGH, spasmodic contraction of the diaphragm (the muscular partition separating the chest cavity from the abdominal cavity) which causes a sudden intake of breath that is involuntarily cut off by closure of the glottis (the opening between the vocal cords), thus producing a characteristic sound. Hiccups arise from various causes, most commonly overdistention of the stomach.

Hypothermia - It decrease the metabolic need for oxygen during certain surgical procedures and for the control of some kinds of cancer.

Hypoxia ( --> Anoxia ) - Condition of the body in which the tissues are starved of oxygen.In its extreme form, where oxygen is entirely absent, the condition is called anoxia.  Diseases of the blood, the heart and circulation, and the lungs may all produce some form of hypoxia.

Inflammation - A localized physical condition in which part of the body becomes reddened, swollen, hot, and often painful, especially as a reaction to injury or infection.

Malignant Hyperthermia - Some tumours are more sensitive than the surrounding healthy tissue to temperatures around 43 degree C (109.4 degree F). Sensitivity to heat is increased in the centre of tumours, where the blood supply is poor and radiation is less effective. A tumour may be heated using microwaves or ultrasound. Hyperthermia may enhance the effect of both radiation and chemotherapy; it is one form of nonionizing radiation therapy.

Jaundice - Excess of bile pigments in the bloodstream and bodily tissues. There is a yellow to orange and, sometimes, even greenish discoloration of the skin, the whites of the eyes, and the mucous membranes. It is best seen in natural daylight and may not be apparent under artificial lighting.

Menstruation Disturbances

Pathologic Processes

Purpura - A rash of purple spots on the skin caused by internal bleeding from small blood vessels.

Retinopathy of Prematurity

Retroperitoneal Fibrosis

Shock - Shock is usually caused by hemorrhage or overwhelming infection and is characterized in most cases by a weak, rapid pulse; low blood pressure; and cold, sweaty skin.

Stress - Any strain or interference that disturbs the functioning of an organism. The human being responds to physical and psychological stress with a combination of psychic and physiological defenses. If the stress is too powerful, or the defenses inadequate, a psychosomatic or other mental disorder may result.

Sudden Infant Death - (SIDS) -  Also called CRIB DEATH, or COT DEATH, unexpected death of an apparently healthy infant from unexplained causes. Sudden infant death syndrome occurs almost always during sleep at night.
