PACES MRCP UK - Where MRCPians Meet Since 2006

MRCP is well establised as an entry exam for advanced specialist training in many countries including Malaysia. It consists of 3 paper i.e. Part1, Part2(written tests) and PACES. PACES in full means Practical Assessment of Clinical Examination Skills. It is the third part and the candidate is assessed by fellows of RCP. I passed my PACES in 2005. I am glad that many seniors had guided me throughout my preparation for PACES and I wish to share my experiences with PACES candidates via this blog.

Third Nerve Palsy

The complete 3rd nerve palsy syndrome:
1) Complete ptosis
2) The eye looks down and out
3) Dilated pupils unreactive to direct light and to accommodation

The 3rd feature is important in differentiating surgical vs medical lesions.

a. SURGICAL lesions
Aneurysms, trauma, & uncal herniation involves the pupil by compression.

b. MEDICAL lesions
Hypertension, diabetes usually spare the pupil because the microangiopathy associated with these medical lesions involves the vasa nervorum, causing neural infarction of the trunk of the nerve, but sparing the superficial pupillary fibres.
