Brain Herniation Syndromes
occur due to the skull being a fixed inflexible space, any rise in pressure is exerted on soft tissues —> compression and shift
cause of raised ICP e.g. haematoma, SAH, ischaemia, mass

Subfalcine 
can lead to compression of the anterior cerebral artery —> contralateral weakness (stroke)
Uncal 
CNIII palsy (ipsilateral dilated pupil, then ophthalmoplegia)
followed by contralateral hemiparesis = false localising sign
Tonsillar = coning
cerbellar tonsils down through foramen magnum
loss of consciousness, abnormal breathing (cheyne-stokes), upgoing plantars
Cushing’s Triad = hypertension, bradycardia, irregular breathing


Never forget that lumbar puncture is contraindicated in most cases of intracranial hypertension (excepting therapeutic use) : otherwise, there’s a severe risk of brain herniation.

CLUBBING

Angle between nail plate and proximal nail fold greater than 180 degrees.

Important causes of clubbing in the adult:

  • Lungs
    • Lung Cancer
    • Bronchiectasis
    • Pulmonary Fibrosis
    • COPD IS NOT A CAUSE OF CLUBBING (if you seen clubbing in a COPD patient, think lung cancer)
  • Heart
    • R to L shunts
    • Endocarditis
    • Pericarditis

hematoxylineosin:

Dyspnea, a subjective experience of uncomfortable breathing, is a symptom that often results from increased work of inhalation and exhalation. Assessment begins by determining the quality and intensity of the discomfort. Dyspnea typically results from cardiopulmonary problems that cause an increased drive to breathe, an increased work of breathing, and/or stimulation of specific receptors in the heart, lungs, or vasculature.
