- Objectives: To investigate the incidence of hyperthyroidism in Stockholm County in those patients who were diagnosed with hyperthyroidism for the First time during the years 2003-2005. Design: All new cases of hyperthyroidism >= 18 years of age were prospectively registered to calculate the total incidence of hyperthyroidism, as well as the incidence of the subgroups: Graves' disease (GD), toxic multinodular goitre and solitary toxic adenoma (STA). Eight specialized units/hospitals in Stockholm County participated in the registration. The participating physicians were all specialists in medical endocrinology. oncology, nuclear medicine or surgery. Results: Duringa 3-year period, 1431 new patients of hyperthyroidism were diagnosed in a well-defined adult population (>18 years of age) of in average 1 457 036 inhabitants. This corresponds to a mean annual incidence of hyperthyroidism of 32.7/100 000. The incidence of GD was 24.5/100 000 per year. toxic nodular goitre was 3.3/100 000 per year and STA was 4.9/100 000 per year. Conclusions: The total incidence of hyperthyroidism in Stockholm County was found to be 32.7/100 000 per year. of which 75% had GD. There were a higher percentage of smokers among the patients with hyperthyroidism compared with the overall population in Stockholm, but no difference in the frequency of smoking between patients with GD and toxic nodular goitre.

- Introduction: The incidence of hyperthyroidism has been reported in various countries to be 23-93/100000 inhabitants per year. This extended study has evaluated the incidence for similar to 40% of the Swedish population of 9 million inhabitants. Sweden is considered to be iodine sufficient country. Methods:All patients including children, who were newly diagnosed with overt hyperthyroidism in the years 2003-2005, were prospectively registered in a multicenter study. The inclusion criteria are as follows:clinical symptoms and/or signs of hyperthyroidism with plasma TSH concentration below 0.2 mIE/l and increased plasma levels of free/total triiodothyronine and/or free/total thyroxine. Patients with relapse of hyperthyroidism or thyroiditis were not included. The diagnosis of Graves' disease (GD), toxic multinodular goiter (TMNG) and solitary toxic adenoma (STA), smoking, initial treatment, occurrence of thyroid-associated eye symptoms/signs, and demographic data were registered. Results:A total of 2916 patients were diagnosed with de novo hyperthyroidism showing the total incidence of 27.6/100 000 inhabitants per year. The incidence of GD was 21.0/100 000 and toxic nodular goiter (TNG=STA+TMNG) occurred in 692 patients, corresponding to an annual incidence of 6.5/100 000. The incidence was higher in women compared with men (4.2:1). Seventy-five percent of the patients were diagnosed with GD, in whom thyroid-associated eye symptoms/signs occurred during diagnosis in every fifth patient. Geographical differences were observed. Conclusion:The incidence of hyperthyroidism in Sweden is in a lower range compared with international reports. Seventy-five percent of patients with hyperthyroidism had GD and 20% of them had thyroid-associated eye symptoms/signs during diagnosis. The observed geographical differences require further studies.

- Objective: Environmental and genetic factors influence thyrotoxicosis, but how population migration affects the disease panorama is not known. fit an urban area in southern Sweden, during the years 1990 until 2003, the population increased from 232 000 to 267 000. In parallel, the proportion of inhabitants born outside Sweden increased. The aim was to investigate whether the incidence of Graves' thyrotoxicosis (GD), toxic multinodular goiter (TMNG), and solitary toxic adenoma (STA) has changed in Malmo since 1990 and to Study the influence of geographic origin. Design and method: An open label prospective registration of thyrotoxicosis, gender, age, smoking habits, and ethnic background during 2003-2005 in an urban area in southern Sweden (Malmo) was undertaken. Results: The total incidence of thyrotoxicosis has changed from 43 to 41.6 cases/100 000/year from the years 1988-1990 to 2003-2005(p-value 0.72). GD increased from 22 to 29.6 (p-value 0.0051). TMNG decreased from 16 to 9.9 (p-value 0.0011) and STA from 4.8 to 2.1. (p-value 0.0054)/100 000/year. The total incidence of GD was higher in inhabitants born Outside Sweden up to the age of 69 years and age-specific incidence showed a peak in women aged 50-59 years old in both groups. The greatest difference between immigrants and Swedes up to the age of 69 years was observed in women aged 20-29 years old. Conclusion: The incidence of GD has increased and of TMNG has decreased in Malmo since 1990. Geographic origin seems to affect the incidence of GD. Whether the observed peak in age-related incidence in women 50-59 years is explained by menopausal changes has to be further investigated.
