Pruritis

Pruritis (also known as itching) is an unpleasant sensation that provokes the desire to scratch. It is a common symptom in many skin conditions, and can also be a symptom of a systemic disease. Pruritis can be localized or generalized and can occur as an acute or chronic condition.

Causes

Pruritis can be caused by a variety of conditions, including:

• Dermatological conditions such as eczema, psoriasis, and urticaria
• Systemic diseases such as liver disease, kidney disease, and thyroid disorders
• Infections such as chickenpox, scabies, and fungal infections
• Allergic reactions to substances such as nickel, rubber, and latex
• Medications such as opioids, antibiotics, and antifungal drugs
• Psychological factors such as stress, anxiety, and depression

Diagnosis

The diagnosis of pruritis is based on a detailed medical history and physical examination. Additional tests may be needed to identify the underlying cause, such as:

• Blood tests
• Skin biopsy
• Allergy testing
• Imaging tests

Treatment

The treatment of pruritis depends on the underlying cause. It may include:

• Topical treatments such as corticosteroids, calcineurin inhibitors, and antihistamines
• Systemic treatments such as antidepressants, antiepileptic drugs, and immunomodulators
• Phototherapy
• Psychotherapy for pruritis related to psychological factors
