goiter/nicotine

BACKGROUND Goiter development depends on genetic and environmental factors. The major environmental factor is iodine intake, whereas diverging results have been published concerning the association between smoking and goiter. METHODS A comparable, cross-sectional study was performed of patients from

The occurrence of thyroid diseases is determined by interplay between genetic and environmental factors. The major environmental factor that determines goiter prevalence is iodine status, but other environmental factors influencing entire populations have been identified such as goitrogens in food

Tobacco smoking increases the risk of goitre and Graves' disease, but the association with thyroid nodularity and hypothyroidism has not been settled. We investigated 4649 subjects from the general population with questionnaires, thyroid ultrasonography and blood tests. The results were analysed in

BACKGROUND Many genetic and environmental factors are involved in the etiology of nicotine dependence. Although several candidate gene variations have been reported by candidate gene studies or genome-wide association studies (GWASs) to be associated with smoking behavior and the vulnerability to

The objective of this study was to determine the impact of cigarette smoking in hyperthyroidism patients. The study group included patients with Graves-Basedow disease (GB): n = 317 (32.9%), patients with Graves' ophthalmopathy (GO): n = 108 (11.2%), patients with toxic nodular goiter (TNG) n = 511

In a survey of 974 villagers (408 males, 566 females; ages = 11-82 years) of the Ai (n = 496; 212 males, 284 females) and Lemanak (n = 478; 196 males, 282 females) rivers in the district of Lubuk Antu in Sarawak's Sri Aman Division during July 1993, goiter was found in 31.8% of the subjects. The

BACKGROUND Sporadic nodular goiter is a common problem in the United States and significant compressive symptoms may occur with progression to a critical size. METHODS Potential epidemiological variables associated with the development of large unilateral (> or = 50 g) and bilateral (> or = 100 g)

Simple nodular goiter and Hashimoto's thyroiditis are 2 frequent nonmalignant thyroid diseases. Tobacco smoking has detrimental effects on the endocrine system and in particular on thyroid function and morphology. The objective of this cross-sectional study, involving 1800 Caucasian adults from a

The Adena pipe figurine was found in the 2000 year-old Adena burial mound in Ross County, Ohio, USA by William C. Mills in 1901. The pipe reportedly represents an achondroplastic dwarf male Native American. However, the clinical aspect (swelling of the neck), the environmental/cultural

The study was aimed at the evaluation of incidence of goiter in the population of the community of Sejny. The survey comprising 1520 subjects revealed the presence of thyroid enlargement in 31.8% of the subjects studied, indicating the occurrence of a mild endemy. The facts speaking for this type of

Both smoking and thyroid dysfunction are frequent in the general population. Many studies have shown that cigarette smoking interferes with thyroid function and with the evolution of thyroid pathology (e.g. goiter formation and thyroid cancer development). Some studies have also suggested a

BACKGROUND The aim of the study was to estimate the influence of nicotine on thyroid volume according to patients' sex. METHODS A group of 160 patients with thyroid disorders in their past medical history was examined. Patients were divided into two groups: Group A contained 50 patients with goiter,

Genetic and a large number of environmental non-iodine-related factors play a role in the cause of nodular goitre. Most evidence for the influence of genetic and environmental factors in the cause of goitre is from cross-sectional, population-based studies. Only a few studies have included

Cost-effectiveness analyses focused on benign thyroid diseases are under-represented in the literature. The calculation of costs per additionally gained life year is difficult: The benefit of prevention is shifted into the distant future. The influence of an untreated subclinical thyroid disease on

The aim of our study was an analysis of cotynine, the main nicotine metabolite in the urine among hyperthyroid patients. The study group included 39 females and 4 males. The mean age was 35.59+/-14.22 yrs. (range: 18-73 yrs.; median: 32 yrs) among hyperthyroid patients suffering from: Graves-Basedow
