In [[1775]], cranial [[osteomyelitis]] was first explained by surgeon Percival Pott as a collection of pus under the pericranium. Dr. Pott reported [[cranial osteomyelitis]] as a consequence of forehead trauma (bone contusion) and extradural hemorrhage
((Pott P. London: L Hawes, W Clarke, R Collins; 1768. Observations on the Nature and Consequences of Those Injuries to Which the Head Is Liable from External Violence.))
Later, it became known that the cause of such an infection was not an injury but the spread of infection from neighbouring structures, for example, [[paranasal sinus]]es. Meltzer and Kelemen first described [[skull base osteomyelitis]] (SBO) in [[1959]] in patients with a burn injury and osteomyelitis of the external auditory canal 
((Meltzer P.E., Kelemen G. Pyocyaneous Osteomyelitis of the Temporal Bone, Mandible and Zygoma. Laryngoscope. 1959;69:1300–1316. doi: 10.1288/00005537-195910000-00006. )).

The term [[laser]] [[thermotherapy]] is an acronym for Light Amplification by Stimulated Emission of Radiation, which first appeared as a term in [[1959]]. [[Laser thermal therapy]] was clinically used for
tissue ablation in [[1966]], based on the theory that the energy produced by [[laser]] light
could achieve a high peak power through a ruby tip and could be absorbed by the surrounding tissue as heat
((H.L. Rosomoff, F. Carroll, Reaction of neoplasm and brain to laser, Arch Neurol, 14
(1966) 143-148.)).

[[Steroid myopathy]] is usually an insidious disease process that causes [[weakness]] mainly to the proximal muscles of the upper and lower limbs and to the neck flexors. Cushing originally described it in [[1932]], and Muller and Kugelberg first studied it systemically in [[1959]].
