    45. Internuclear opthalmoplegia: medial longitudinal fasciculus connects CN nucleus 3-4. Ipsilateral adduction palsy, contralateral nystagmus. Aide memoire (TRIES TO YANK THE ipsilateral BAD EYE ACROSS THE NOSE). Convergence retraction nystagmus, but convergence reflex is normal. Causes: MS, SLE, Miller fisher, overdose(barb, phenytoin, TCA), Wernicke.
    46. Progressive Supranuclear palsy: Steel Richardson. Absent voluntary downward gaze, normal dolls eye. i.e. Occulomotor nuclei intact, supranuclear pathology.

    59. painful 3rd nerve palsy -> posterior communicating artery aneurysm till proven otherwise
    60 late complication of scleroderma --> pumonaryhypertention plus/minus fibrosis.
    61. causes of erythema mutliforme: lamotrigine
    62. vomiting, abdominal pain, hypothyroidism -> Addisonian crisis (TFT typically abnormal in this setting DO NOT give thyroxine).
    63. mouth/genital ulcers and oligarthritis -> behcets (also eye/skin lesions, DVT)
    64. mixed drug overdose most important step -> Nacetylcysteine (time dependent prognosis)
    65. cavernous sinus syndrome - 3rd nerve palsy, proptosis, periorbital swlling, conj injectn
    66. asymetric parkinsons -> likely to be idiopathic
    67. Obese, NIDDM female with abnormal LFT's -> NASH (non-alcoholic steatotic hepatitis)
    68. fluctuating level of conciousness in elderly plus/minus deterioration --> chronic subdural. Can last even longer than 6 months
    69. Sensitivity --> TP/(TP plus FN) e.g. For SLE - ANA highly sens, dsDNA:highly specific
    70. RR is 8%. NNT is ----> 100/8 --> 50/4 --> 25/2 --> 13.5
    71. ipsilateral ataxia, Horners, contralateral loss pain/temp --> PICA stroke (lateral medulary syndrome of Wallenburg)
    72. renal stones (80% calcium, 10% uric acid, 5% ammonium (proteus), 3% other). Uric acid and cyteine stone are radioluscent.
    73. hyperprolactinaemia (allactorrohea, amenorrohea, low FSH/LH) -> Da antags (metoclopramide, chlorpromazine, cimetidine NOT TCA's), pregnancy, PCOS, pit tumor/microadenoma, stress.
