1. Introduction Thyroid disorders represent a prevalent category of endocrine disease, with hypothyroidism and hyperthyroidism constituting the primary manifestations of thyroid dysfunction. These conditions arise from an imbalance in the production of thyroid hormones—thyroxine (T4) and triiodothyronine (T3)—which are critical regulators of basal metabolic rate, thermogenesis, growth, and development. The clinical management of these disorders … Read more
1. Introduction Gout represents the most common form of inflammatory arthritis in adults, arising from the deposition of monosodium urate crystals in joints and other tissues.
