Dermatology History

Treat the interaction as a conversation with the owner while examining the patient.
Integrate questions into the physical exam to save time.
Recognize the significance of history taking due to similarities in dermatological presentations.
Acknowledge the overlap of various conditions (e.g., allergies, infections, comorbidities).

Identify what the client is most concerned about.
- Example: Case from the ophthalmology department about a bulldog with dystrophic nails.
- Contextualizing the presenting complaint can guide future diagnostics and treatments.

Ask specifically how long the problem has been occurring.
- Clarify vague responses like "forever"; inquire about first noticed symptoms.
- Example: Inquiring about a golden retriever licking its paws since it was a puppy versus starting at two years of age.
The history of past symptoms can guide diagnostic considerations:
- Early onset issues may indicate allergies or ectoparasites.
- Long-standing issues in older patients may suggest neoplasia or endocrine disorders.

Track the progression of symptoms over time, particularly for allergic patients.
- Seasonal symptoms may transition to nonseasonal as pets mature.
- Owners may report worsening symptoms or new issues that have arisen.
- Important to assess changes in lesions, severity, and symptom persistence.

Inquire about the first signs noticed by the owner.
- Distinguish between an itch causing a rash versus a rash leading to an itch.
- Example: A pet that itches leading to a rash is different from a rash that does not elicit itch immediately.

Be precise about the locations of pruritus the owners have observed.
- Specific areas may indicate different conditions (e.g., dorsal lumbosacral region could indicate flea allergies).
Multiple locations of symptoms can complicate diagnosis.
Owners must be encouraged to provide locations of continuous or seasonal itching alongside any change in patterns.

Discuss any changes in the pet's environment or location that could impact symptoms.
- Changes in severity based on climate or geographical areas might suggest environmental allergies.
Awareness of flea populations in different regions and seasons.
Evaluate instances where steroids may have masked symptoms (e.g., long-acting injections).

Investigate past and current medications the pet has received.
- Clarify steroid usage, antibiotic history, and any topical treatments used alongside timeframes.
- Owners often misinterpret the effectiveness of treatments when combined with other medications (e.g., antibiotics alongside steroids).

Discuss responses to medications, including steroids, antibiotics, and dietary changes.
- Owner perceptions of effectiveness may be influenced by concurrent treatments.
Thoroughly assess dietary trials and any potential non-compliance during trials (e.g., missed restrictions).
- Strictness of diets can heavily impact diagnosis of food allergies.

Ask ownership about current medication regimen.
- Confirm that pets are receiving the correct medications as intended.
- Avoid assumptions based on past purchasing records.

Introduce and utilize the PVAS scale for assessing itch severity.
- Scale from 1 to 10; useful for both initial assessments and follow-ups.
- Helps standardize subjective levels of itch perceived by pet owners.
Use this scoring as a reference point when discussing treatment efficacy over time.

Inquire whether the owner has noticed other signs like weight changes, diarrhea, or respiratory issues.
- Cats may not overtly show itching due to their behavior, but can exhibit symptoms like hairballs.
Discuss the overall care routine, including bathing frequency and products used.

Emphasize the importance of thorough history taking in dermatology.
Encourage using efficient methods (forms, staff assistance) to streamline the conversation.
Stress that understanding a patient’s full history will facilitate more effective diagnostics and alleviate frustrations for both pet and owner.
Aim to alleviate itching and improve overall quality of care.
