Introduction: Acromegaly is a rare disease caused by GH hypersecretion from a pituitary adenoma. However, accurate estimates of incidence and prevalence are scarce and not based on nationwide populations. It is well known that surgical cure may normalize mortality and improve morbidity but similar data are not available for patients receiving medical treatment.Method: We first validated the ICD-8 and ICD-10 diagnosis codes for acromegaly in The National ...

Objective: The aim of this study was to examine the urinary iodine concentrations (UIC) in an adult population in the Faroe Islands. Iodine status in the adult population assumed to be sufficient due to the high frequency of seafood consumption1 although UIC has not been investigated previously in the Faroe Islands. World Health Organization recommends monitoring iodine status in all populations. Iodine nutrition is a key determinant of thyroid disease risk<p class="abstex...

Objective: The risk of aortic dissection is 100-fold increased in Turner syndrome (TS). Increased blood pressure (BP) and heart rate is present as well as an increased risk of ischemic heart disease and diabetes. This study aimed to prospectively assess heart rate variability (HRV) in TS and its relation to aortic dimensions.Methods: Adults with TS (n=91, aged 37.4±10.4 years) recruited through the Danish National Society of Turner Syndrome...

GH is an important regulator of longitudinal growth in children and metabolism in adults. GH is used for treatment deficiency disorders in both children and adults. GH treatment is safe and well tolerated. However, its clinical use is limited to daily s.c. injections which poses a challenge for both the patients and the physicians and has prompted research into alternative approaches to GH treatment.NNC0195-0092 is a hGH derivative conjugated with an alb...

Introduction: Low androgen levels are associated with decreased sexual activity. However, to our knowledge no population based study has evaluated the association between androgen levels and sexual activity in young men.Aim: To evaluate associations between androgen levels and sexual activity in young men.Design: Seven hundred and seventy-three Danish men, aged 20–29 years, underwent clinical and biochemical examination: Total...

Objective: The cardiovascular effects of testosterone treatment are debated. Osteoprotegerin (OPG) is an independent marker of cardiovascular risk. We investigated the effect of testosterone therapy on OPG levels in ageing men with low normal bioavailable testosterone levels.Design: A randomized, double-blinded, placebo-controlled study of six months testosterone therapy (gel) in 38 men aged 60–78 years with bioavailable testosterone <7.3 nmol/l...

Objective: Smoking may be associated with changes in metabolic risk factors and sex hormones in PCOS.Design: Retrospective trans-sectional study.Patients: Six hundred and fifty caucasian premenopausal women with the diagnoses hirsutism or PCOS were divided according to smoking status: Non-smokers (NS-PCOS=390) and smokers (S-PCOS=260). 119 healthy women were studied as controls (NS-Control=105, S-Control=14)....

Background: The indication for testosterone therapy in ageing hypogonadal men without hypothalamic, pituitary or testicular disease remains to be elucidated. The aim of this study was to investigate the effect of testosterone therapy on insulin sensitivity, substrate metabolism, body composition and lipids in ageing men with relative hypogonadism using a predefined cut-off level for bioavailable testosterone.Methods: A randomized, double-blinded, placebo...

Background: Aortic dissection causes excess mortality in Turner syndrome, and this increased risk is associated with aortic dilation, congenital cardiovascular abnormalities, karyotype, and blood pressure. But risk factor identification is inadequate, and the natural course of aortopathy in Turner syndrome is poorly investigated.Design and methods: Prospective follow-up study in women with Turner syndrome (n=102, examined twice) and healthy age-ma...

Background: PPARγ-agonist treatment may decrease bone mineral density (BMD) in postmenopausal women. The hypothesis that premenopausal women are relatively protected from mineral loss during PPARγ-agonist treatment has not been evaluated in clinical studies.Aim: To investigate the effect of pioglitazone on BMD and bone turnover markers in patients with polycystic ovary syndrome (PCOS).Methods: Thirty premenopausal PCOS pa...
