SCENARIO

Sarah Williams, a 17-year-old high school student, presents with moderate acne affecting her face and upper back. She has been using over-the-counter cleansers and topical treatments, but her acne has not improved. She describes feeling self-conscious and withdrawn, often avoiding social situations.

She also mentions irregular periods, which have been present since menarche, raising the possibility of PCOS. She is concerned about scarring and wants to discuss effective treatments, but is worried about side effects of prescription medications.

On examination, Sarah has moderate inflammatory acne, with papules and pustules on her cheeks, chin, and upper back, along with mild post-inflammatory hyperpigmentation. No deep nodules or cystic lesions are present.

She is seeking guidance on treatment options, including whether she should consider oral therapy or hormonal treatments.

THE COMPETENT CANDIDATE

The competent candidate should be able to:

Q1: What aspects of history and examination are critical in assessing this patient’s acne?

A structured approach is essential when evaluating acne to determine severity, potential underlying causes, and appropriate treatment options.

1. History

  • Onset and duration: When did the acne start? Has it worsened over time?
  • Lesion type and distribution: Presence of comedones, papules, pustules, nodules, or cysts, and affected areas (face, back, chest).
  • Previous treatments: Any over-the-counter or prescription treatments, response, and adherence.
  • Skin and hair care routine: Type of cleansers, moisturisers, makeup, or hair products used.
  • Hormonal influences: Irregular periods, hirsutism, weight gain (suggestive of PCOS).
  • Family history: Parental acne history and treatment response.
  • Lifestyle factors: Diet (high glycaemic foods, dairy), stress, and sleep patterns.
  • Medications: Use of steroids, oral contraceptives, lithium, or other acne-triggering drugs.
  • Psychosocial impact: Self-esteem issues, social withdrawal, anxiety, or depression.

2. Examination

  • Skin assessment: Presence of comedonal, inflammatory, or cystic acne, scarring, or post-inflammatory hyperpigmentation.
  • Hormonal signs: Look for hirsutism, acanthosis nigricans, or male-pattern hair loss, which may indicate PCOS.
  • General examination: BMI, signs of insulin resistance, or features of androgen excess.
  • Acne severity grading:
    • Mild: Comedones, few inflammatory lesions.
    • Moderate: Widespread papules, pustules, mild scarring.
    • Severe: Nodules, cysts, extensive inflammation, scarring.

This assessment guides the choice of treatment, considering whether lifestyle changes, topical agents, systemic therapy, or referral is required.


SUMMARY OF A COMPETENT ANSWER

  • Elicits acne history thoroughly, including triggers, treatments, and psychosocial impact.
  • Assesses lesion type, severity, and distribution to guide treatment selection.
  • Considers hormonal and systemic causes, such as PCOS.
  • Identifies acne complications, including scarring and post-inflammatory hyperpigmentation.

PITFALLS

  • Failing to assess hormonal influences, potentially missing PCOS-related acne.
  • Not exploring previous treatments, leading to ineffective or redundant therapies.
  • Ignoring psychosocial impact, which can significantly affect mental health and quality of life.
  • Overlooking dietary and lifestyle factors, which may contribute to acne severity.
