### medical emergency:

Meningococcal disease
* are infections caused by the bacteria called meningococcus.
* can affect people at any age
  - also cause blood infections
  - be rapidly progressive
  - progress rapidly
  - spread from person to person
* has two main manifestations, meningitis and septicaemia.
* is among the most feared infectious diseases.
* is an infection caused by bacteria
  - infectious disease that peaks during winter
  - uncommon but serious disease
  - caused by a bacteria
  - difficult to detect because it can be mistaken for other conditions
  - quite rare but can be life threatening
  - rare, but potentially deadly
  - relatively rare
  - treated with injected or intravenous antibiotics
* is very rare
  - uncommon but very serious
* occur most often in children and young adults.
* occurs seasonally in some regions of the world.
* potentially fatal bacterial infection commonly referred to as meningitis
  - life-threatening bacterial infection
* rare but potentially fatal bacterial infection.
* refers to the disease problems that meningococcus causes.
* relatively rare disease and is usually found as a single sporadic case.
* requires early recognition, appropriate tests and antibiotics.
* serious illness caused by bacterial infection
  - illness, caused by a bacteria
* severe bacterial infection.
* spreads by respiratory droplets.

Severe depression
* More severe depression can include thoughts of utter futility and suicide.
* can also affect the appetite, resulting in weight loss
  - include hallucinations and, in some cases, suicide attempts
  - lead to suicide
* is correlated with high blood-caffeine levels
  - thought to have a genetic component

### medical emergency:

Unstable angina
* can be difficult to distinguish from acute myocardial infarction.
* can be the indication of a heart attack in the near future
  - warning of a heart attack in the near future
* is angina that occurs sporadically, or unpredicatably, or at rest
  - caused by the partial blockage of the blood supply to the heart muscle
  - characterized by symptoms that are new or increasing
  - pain with a changing pattern
  - so-called because it can strike at any time even when resting
  - when it occurs at rest or at varying levels of exertion
* serious condition that can lead to a heart attack or death
* severe condition and usually requires hospitalization.
* type of severe chest pain that can be a warning sign of heart attack.

### medical imaging:

Pet scan
* PET scans are pictures of the actual biological functioning of the human body
  - the only ones that can show functioning areas of the brain
* PET scans can help determine the resectability of a known tumor
  - spot heart disease and compute blood flow
  - confirm that memory tasks require the involvement of a range of brain areas
  - monitor short-lived radioactive isotopes of oxygen that have been injected into the blood
  - reveal metabolic activity in the brain
  - show reduced metabolic activity in schizophrenics
* PET scans track blood flow in the brain and show which areas become active during selected tasks
  - the flow of radioactively labelled blood in the brain
* PET scans use a radioactive tag that can show how much glucose cells are using
  - radioactively labeled glucose to detect sugar-hungry tumor cells
* are medical imaging

### medical language specialty:

Medical transcription
* is also one of the fastest growing at-home professions
  - one of the most important fields in the healthcare industry
* is the process of translating digitised audio medical records into text form
  - turning physician dictated notes into written transcripts
* medical language specialty.
* portable skill that allows for professional and geographic mobility.
* production-oriented industry.
* profession that offers great flexibility and unique employment.
