Dermatology

This edition of check considers the investigation and management of skin and nail conditions in general practice.

Skin conditions are one of the most common presentations in Australian general practice, accounting for 17 out of every 100 patient encounters.

In Australia, acne is seen by general practitioners (GPs) at a frequency of 0.4 of every 100 consultations. Acne affects approximately 93.3% of teenagers aged 16–18 years, but it can also persist into adulthood, with data showing 64% of those aged 20–29 years and 43% of those aged 30–39 years affected.

Vitiligo affects approximately 1–2% of the population. It can begin at any age, but 50% of cases commence prior to the age of 20 years.

Psoriasis is thought to affect at least 2% of Australians; GPs are well placed to diagnose both psoriasis and common comorbidities such as psoriatic arthritis, metabolic syndrome and cardiovascular disease.

Nail problems are common presentations to general practice; onychomycosis has a prevalence of up to 50% in people aged over 70 years, while nail psoriasis presents as an isolated symptom in 5–10% of patients but affects half of patients with psoriasis.


Learning outcomes

At the end of this activity, participants will be able to:

  • outline the various treatment options available for acne, taking into account the stage of acne
  • summarise the comorbidities that are associated with psoriasis
  • describe the management of a patient presenting with signs of onychomycosis
  • discuss the indicators of prognosis in vitiligo.

Case studies

Below is a list of the case studies found in this month's edition of check. To see how these case studies unfold and gain valuable insights into this months topic, log into gplearning to complete the course.

Sabina, aged 54 years, presents with a generalised skin eruption that started two weeks ago. She complains of pruritic scaly lesions on her elbow, beneath her breasts, on her back and around her vagina. She works in a nursing home and is quite worried about having contracted an infectious skin disease. She has trouble sleeping because of the pruritus. Sabina is anxious about the cause of her rash.

Chad, a Caucasian man aged 65 years, presents to you on insistence from his wife with concerns about his ‘ugly toenails’. He has noticed some discolouration and distortion affecting the two great toenails for at least the past 12 months, and it seems to be getting worse. Chad has hypertension and takes ramipril 2.5 mg to treat this condition. He has no other known medical conditions and does not take any other medications. He rarely drinks alcohol, and he smokes occasionally at parties.

Xanthe, aged 30 years, presents with concerns about her acne. She reports mild acne as a teen, which became more severe in her early twenties when she ceased her contraceptive pill. Xanthe currently uses a 2% salicylic acid cleanser and gentle moisturiser. She took doxycycline for six months last year with only mild improvement.

Tobias, a man aged 40 years, attends your general practice reporting whitening of the skin on his hands and forearms that has become more prominent over the summer months. He works as a salesman. He is Fitzpatrick skin type 3.
