Dermatology is the study of the diagnosis, treatment, and prevention of diseases of the skin, hair, nails, oral cavity and genitals. Medicos Library has provided high standard Dermatology Notes by Dr. Yousif Abdallah Hamad.

Summary of Notes:


  • The epidermis is the outermost layer of the skin and is composed of a stratified squamous
    epithelium with an underlying basal lamina

Acne rosacea is a chronic skin disease of unknown aetiology

  • typically affects nose, cheeks and forehead
  • flushing is often first symptom
  • telangiectasia are common
  • later develops into persistent erythema with papules and pustules
  • rhinophyma
  • ocular involvement: blepharitis


  • topical metronidazole may be used for mild symptoms (i.e. Limited number of papules and
    pustules, no plaques)
  • more severe disease is treated with systemic antibiotics e.g. Oxytetracycline
  • recommend daily application of a high-factor sunscreen
  • camouflage creams may help conceal redness
  • laser therapy may be appropriate for patients with prominent telangiectasia

Acne vulgaris
 Acne vulgaris is a common skin disorder which usually occurs in adolescence.
 It typically affects the face, neck and upper trunk
 characterised by the obstruction of the pilosebaceous follicle with keratin plugs which results in
comedones, inflammation and pustules.

 affects around 80-90% of teenagers, 60% of whom seek medical advice
 acne may also persist beyond adolescence, with 10-15% of females and 5% of males over 25
years old being affected
Pathophysiology is multifactorial
 follicular epidermal hyperproliferation resulting in the formation of a keratin plug. This in turn
causes obstruction of the pilosebaceous follicle. Activity of sebaceous glands may be
controlled by androgen, although levels are often normal in patients with acne
 colonisation by the anaerobic bacterium Propionibacterium acnes
 inflammation

How to use the notes to study for MRCP:

  • Initially, you need to skim through the notes at least twice to build up an idea about the syllabus of MRCP. Highlight any portion that is difficult so that you can concentrate on that during your revision.
  • Next proceed to the question banks. You can choose to do Passmedicine, onexamination or Pastest. I usually recommend students to do Passmedicine and the Pastest.
  • As you go through the questions make a super-revised notes of your own. Write down in one sentence what you learned from the question you just attempted.
  • If you get any question wrong or you get confused then return to the notes and re-read one more time before attempting the question again. And write down the point in red in you revision notes so that you can skim through it easily during your revision.
  • I have highlighted some points in yellow and green to help you concentrate on those points. As you go through passmedicine and pastest, you can highlight the points further to help in your revision.
  • During your revision before the main exam, only read the highlighted portions including those that you highlighted when practicing the question bank. And also read your super-revised notes that you made from the question banks.

I believe these method has worked for many students and will help you in your journey to be successful in MRCP part 1 and as well as build your basics for Part 2.
