The fungus Cryptococcus gattii, contracted through inhalation of spores.
Commonly grows in tropical and subtropical climes, yet has appeared in British Columbia, Canada and the Pacific Northwest as the climate warms.

incision into an anatomical partitions (a septum) to create passage between two adjacent cavities.
eg. atrial septotomy
procedure to allow oxygenated and non oxygenated blood mix in the heart atria to temporarily improve blood oxygen levels prior to repair of congenital pulmonary artery and vein heart defect (oxygenated blood is not properly circulated past the lungs).
during heart surgery the septotomy will be repaired after the blood vessels are surgically placed in their correct anatomical positions.
below: a congenital septal defect.
used by congenital heart surgeons as a staged approach to operative correction of congenital heart defects.
reduce excessive pulmonary blood flow and protect the pulmonary vasculature from hypertrophy and irreversible pulmonary hypertension.
a form of multi-infarct dementia caused by damage to the white brain matter.
White matter atrophy can be caused by:
- chronic HTN
- the aging process
loss of memory and intellectual function ( collectively known as executive brain functioning)
changes in mood.
A specific form of hydrocephalus in which the central cavities of the inner brain (the ventricles) enlarge at the expense of the substance of the brain, while the pressure of the CSF remains within normal range.
accumulation of excess of cerebrospinal fluid in the brain.
- loss of bladder control
- difficulty walking
placement of a shunt to relieve excess fluid and decrease intra-cranial pressure.
a rare inherited disorder of copper metabolism.
copper accumulates in the liver and then in the red blood cells and in tissues;
neurological or psychiatric symptoms and liver disease.
Treatment and Management:
- decrease dietary copper intake: low-containing foods such as mushrooms, nuts, chocolate, dried fruit, liver, and shellfish is recommended.
- increase the excretion of copper in urine and feces.
Inability to recognize objects by use of the senses (athough the sensory mechanism is intact).
A loss of ability to recognize objects, persons, sounds, shapes, or smells while the specific sense is not defective nor is there any significant memory loss.
