Correction

Abstract

I n the November 2010 issue of Thyroid (vol. 20, no. 10; 1205–1208), corrections are required in Table 1 of the article “The Prevalence of Polycystic Thyroid Disease in Hypothyroid Patients with Negative Thyroid Antibodies,” by Sumihisa Kubota et al. The Table 1 published in the November 2010 issue of Thyroid should have been changed as the definition of overt hypothyroidism was changed from “patients having a serum TSH of >10 μU/mL” to “patients having a serum TSH of >10 μU/mL and a free thyroxine level of below 0.7 ng/dL,” reducing the total number of patients with overt hypothyroidism from 115 to 71. The correct Table 1 is presented herewith.

Table 1.

Causes of Overt Hypothyroidism in the Patients Negative for Both Thyroglobulin and Thyroid Peroxidase Antibodies

Causes	Number of patients (M/F)	Age (years)	FT4 (ng/dL)	FT3 (pg/mL)	TSH (μU/mL)	Remarks
Polycystic thyroid disease	24 (11/13)	71.54 ± 9.64	0.51 ± 0.14	2.16 ± 0.54	48.37 ± 30.05	Excess iodine intake in 17
Polycystic thyroid disease suspected	4 (0/4)	68.00 ± 7.52	0.55 ± 0.05	2.41 ± 0.22	25.75 ± 8.38	Excess iodine intake in 3
Graves' disease	14 (4/10)	49.35 ± 19.27	0.45 ± 0.16	2.01 ± 0.66	43.89 ± 27.77	Excess ATD in 11, after RAIT in 3
Hashimoto's thyroiditis	6 (1/5)	50.17 ± 19.11	0.38 ± 0.14	1.74 ± 0.68	85.46 ± 35.61
After subacute thyroiditis	2 (1/1)	64.5 ± 4.95	0.64 ± 0.05	2.24 ± 0.06	14.74 ± 5.70
After silent thyroiditis	1 (0/1)	35	0.47	2.81	45.5	Postpartum in 1
After external radiation in the neck	1 (1/0)	81	0.49	2.59	72.3	Excess iodine intake in 1
Multinodular goiter	1 (1/0)	64	0.57	3.02	14.15
Congenital thyroid abnormality	1 (0/1)	34	0.2	1.41	100	Hemiagenesis in 1
Lithium carbonate	1 (0/1)	61	0.3	1.9	100	Excess iodine intake in 1
Unidentified	16 (8/8)	63.06 ± 13.84	0.48 ± 0.15	2.05 ± 0.49	48.31 ± 35.30	Excess iodine intake in 9
Total	71	61.89 ± 16.55	0.48 ± 0.15	2.10 ± 0.56	49.66 ± 32.93

Values are means ± SD. Normal range: FT4 0.70–1.60 ng/dL, FT3 1.70–3.70 pg/mL, TSH 0.30–5.00 μU/mL.

ATD, antithyroid drug; FT3, free triiodothyronine; FT4, free thyroxine; TSH, thyrotropin; SD, standard deviation; RAIT, radioactive iodine therapy.
