Final answer:
Controlling flare factors of pruritus, such as in Crohn's disease, makes it easier to manage the symptoms of the condition. Topical corticosteroid creams like hydrocortisone don't treat the underlying cause of a rash but help relieve symptoms by reducing inflammation and histamine levels.
Step-by-step explanation:
The question initially seems to blend the topic of mathematics with a medical issue but is actually focused on a health-related concern regarding pruritus (itching) which is a symptom commonly experienced by individuals with skin conditions or diseases like Crohn's. When talking about the summation of pruritus and the ability to control flare factors, it typically refers to managing the triggers that exacerbate the condition.
In the context provided, hydrocortisone creams are used to treat pruritus. This topical corticosteroid doesn't treat the root cause of the rash but is effective in controlling the symptoms, especially the itching. By reducing histamine levels and inflammation in the skin, these creams make it easier to control the discomfort and potential skin damage caused by scratching.
For chronic conditions like Crohn's disease, controlling flare factors might involve medication, dietary changes, and lifestyle adjustments, which would lead to better symptom management and potentially extended periods of remission. Therefore, controlling flare factors makes it easier to manage the overall disease and reduce the impact on the patient's quality of life.
