Hyperthyroidism is the overactivity of the thyroid gland resulting in excessive production of thyroid hormones.
Symptoms are of gradual onset.
Earliest signs may be emotional lability and motor hyperactivity; decline in school performance may also be noted.
Causes are autoimmune (Grave's disease), inappropriate stimulation by trophic factors, passive release of preformed thyroid hormone stores in response to infections, trauma, or other offensive factors inside the body, and extra-thyroidal sources.
Most children treated with discordant antibiotics for third-generation cephalosporin-resistant urinary tract infections (UTIs) may experience initial clinical improvement, with only a few requiring escalation of care, according to a study. This highlights the aptness of using current narrow-spectrum empiric therapy regimens while awaiting final urine culture results.
