How to use AJGP for your CPD
Each issue of the Australian Journal of General Practice (AJGP) has a focus on a specific clinical or health topic. Many GPs find the entire issue of interest and of relevance to their practice; some GPs find one or more articles in the journal relevant.

You can use AJGP for your CPD. If you want to use the entire issue for CPD, you must work your way carefully through each article in the issue and complete the Clinical challenge. When you do this, take time to read the articles carefully and critically, and think carefully about how you might adjust your practice in response to what you have learned.

We recommend that you access AJGP, the articles and the Clinical challenge through gplearning (Activity ID: 583034). Then, when you complete the articles and the Clinical challenge, your CPD hours are automatically credited to your CPD account. If you work through the full issue of AJGP and complete the Clinical challenge, you will receive 10 CPD hours (five hours’ Educational Activities and five hours’ Reviewing Performance).

If you do not want to do the full AJGP issue, and you prefer to select one or more articles to read, you can QuickLog the CPD hours directly through your myCPD dashboard. As guidance, each article in AJGP would provide 1–2 CPD hours, split half Educational Activities and half Reviewing Performance.

These questions are based on the Focus articles in this issue. Please choose the single best answer for each question.

Question 5

Pain that arises from actual or threatened damage to non-neural tissue and is due to the activation of nociceptors is classified as:

  1. referred
  2. nociceptive
  3. nociplastic
  4. neuropathic
Question 6

Pain that arises from altered nociception, despite no clear evidence of actual or threatened tissue damage causing the activation of peripheral nociceptors or evidence for disease or lesion of the somatosensory system causing the pain, is known as:

  1. nociceptive
  2. referred
  3. nociplastic
  4. neuropathic
Question 7

Pain caused by a lesion or disease of the somatosensory nervous system is known as:

  1. neuropathic
  2. nociceptive
  3. nociplastic
  4. referred
Question 8

Pain occurs when nociceptors are stimulated at a specific site and the brain interprets the pain as coming from a different area due to convergence of neural pathways. This is classified as:

  1. nociceptive
  2. nociceptive referred
  3. neuropathic
  4. nociplastic

Case 5

Din, a man aged 72 years, with a background of type 2 diabetes mellitus, reports difficulty exercising due to peripheral neuropathy.

Question 9

Personal Activity Intelligence (PAI; www.ntnu.edu/cerg/personal-activity-intelligence) is a heart rate-based technology that converts an individual’s heart rate responses to:

  1. muscular contraction
  2. reward points
  3. physical activity
  4. personal motivation
Question 10

Heart rate responses to exercise might be influenced by comorbidities such as cardiac autonomic neuropathy or medications such as:

  1. ibuprofen
  2. statins
  3. clopidogrel
  4. beta-blockers

October 2023 Short answer question answers

Answer 1

‘Skin of colour’ is a term that was coined in North America to describe a heterogeneous group of people that have pigmented skin types.

Answer 2

There are two broad categories of vitiligo: (1) a non-segmental variant, which is the more common type, involving many areas of the body; and (2) a segmental variant, which follows a dermatomal-type distribution and is seen in approximately 2% of those with vitiligo.

Answer 3

Four therapies currently used to treat vitiligo are:

  • topical calcineurin inhibitors for the face and potent and ultrapotent topical steroids for the body
  • narrowband ultraviolet B (NB-UVB) light therapy
  • targeted UVB phototherapy such as excimer laser
  • immunosuppressive therapies such as oral corticosteroids, steroid sparing therapies such as methotrexate and Janus kinase inhibitors such as tofacitinib.
Answer 4

Two surgical options for the management of vitiligo are: (1) tissue grafts, whereby solid tissue is transferred from donor to recipient; and (2) cellular grafts, which involve the transfer of suspensions of melanocytes to a larger body surface area of the recipient.

Answer 5

The treatment typically used for widespread progressive vitiligo is pulsed steroid therapy.

Answer 6

‘Koebner phenomenon’ is associated with vitiligo, whereby trauma to the skin can trigger new lesions.

Answer 7

Hypopigmentation appears as poorly demarcated, slightly lighter areas of skin, whereas vitiligo is seen as well-demarcated, stark white macules anywhere on the face, body, genitals, mucosa and/or hair.

Answer 8

Four significant quality-of-life impairments in children with severe atopic dermatitis are:

  • school absenteeism
