Abstract
Background
The aim of this study was to evaluate thyroid and parathyroid functions as a cause of sudden onset dizziness (SOD) in patients who were admitted to the Emergency Department (ED).
Material/Methods
This study was conducted prospectively in 100 patients with sudden onset dizziness (SOD) admitted to the ED. Neurologic, ear-nose-throat, detailed neck examinations, serum calcium levels, thyroid function tests (TFT), and parathormone and thyroid ultrasounds were performed on all patients in our study.
Results
Thirty-seven (37%) females and 63 (63%) males were included in this study. Four patients (4%) had elevated serum TSH levels, 6 (6%) had decreased serum fT3 levels, 10 (10%) had decreased serum fT4 levels, 2 (2%) had elevated serum fT4 levels, and 2 (2%) had elevated serum parathormone levels. In 4 (4%) patients, the serum calcium levels were lower than normal, and 2 (50%) of these patients had symptomatic hypocalcemia. Thyroid ultrasound examinations showed multinodular goiter in 28 (28%) patients, 2 (2%) patients had thyroiditis, 12 (12%) had an isolated unilateral nodule, and 58 (58%) had normal thyroid tissues.
Conclusions
We suggest that detailed neck examination, TFT, and thyroid ultrasound examination should be considered in the diagnostic algorithms of SOD to provide rapid diagnosis and proper treatment for a patient in the ED.
