IMM THEORY MEDICINE
These are the ESSENTIAL POINTS FOR FCPS IMM THEORY (MEDICINE). They are compiled from multiple sources and should ideally be given one or two reads one week prior to the exam. The points which are new to you should be marked or highlighted and the points which you already know should be left as it is. Write down the new points , separately​. As you have an idea of CPSP exams, there are many points and association in this collection which you just need to know in order to get through some questions and there isn’t much logic involved there.
  • Pseudo Bulbar ===> Spastic tongue
  • Bulbar ==> Flaccid and wasted tongue
  • Raised Calcium + inappropriately raised or normal PTH ==> Primary Hyperparathyroidism
  • Vitamin D increases both Ca and PO4 plasma levels.
  • PTH is Phosphate Trasher so decreases its levels.
  • Calcium levels are unaffected by hypophosphatemia.
  • Carbimazole can be given in 3rd trimester.

  • DPP4 inhibitors e.g Sitagliptin are weight neutral i.e dont cause weight gain or loss.
  • Oral glucose causes an increased insulin release than an IV dose. This is mediated by GLP 1 and is known as the INCRETIN effect. GLP 1 is low in T 2 Diabetes.

    a) Polycythemia
    b) Hypofibrinogenemia
