Background: Replicating the physiological cortisol secretion is key in treatment of glucocorticoid insufficient individuals. A sub-optimal replication may explain the impaired quality of life experienced by these individuals. The study investigates fatigue measured by ecological momentary assessments in patients treated with conventional hydrocortisone compared with a once-daily dual-release formula of hydrocortisone (Plenadren) that follows the cortisol physiology more closel...

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...

Hypothesis: We hypothesised that damage to the hypothalamus by local tumour, surgical treatment, or irradiation might involve the suprachiasmatic nucleus and thereby melatonin secretion, leading to disturbed circadian function and clinical manifestations such as daytime sleepiness and fatigue in craniopharyngeoma patients.Objective: We aimed to assess the influence of craniopharyngiomas and their treatment on melatonin secretion, sleep pattern, sleep qua...

Introduction: Recently, it has been suggested that hypopituitarism developed after the brain injury has implications in the final recovery of the patients. We hypothesize that hypopituitarism developed in the course of traumatic brain injury (TBI) or non-TBI is related to worse functional outcome. The aim was to assess the association between hypopituitarism in the early recovery phase and long-term functional outcome.Materials and methods: We included 1...

Background: Hyperthyroidism has been associated with increased all-cause mortality. Whether the underlying cause of hyperthyroidism influences this association is unclear. Our hypothesis was that Graves’ disease (GD) and toxic nodular goiter (TNG) differ with respect to mortality risk and cause of death.Methods: An observational cohort study, using record-linkage data from nation-wide Danish health registers. 1.291 and 861 subjects with GD and TNG, ...

Background: Hypothyroidism has been linked with an increased risk of morbidity such as cardiovascular disease and diabetes mellitus. However, it is unknown whether the burden of morbidity is present before or after the diagnosis of hypothyroidism.Aim: Evaluate the temporality and type of morbidity in hypothyroid patients.Methods: Observational cohort study. Based on record-linking between official Danish health registers 2822 subje...

Background: Previous studies have demonstrated a high overall prevalence of testicular adrenal rest tumors (TART) in adults with congenital adrenal hyperplasia (CAH), whereas little is known about the prevalence in children. The aim of this study was to determine the presence of TART according to age and genotype.Design: Retrospective study, tertiary University centre.Patients and methods: In 47 male patients (age 2.6–40.3 yea...

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...

Background: Birth weight has been associated with low bone mass in later life. Previous studies, however, have relied on self-reported data on birth weight, included select populations, or been of a limited size. Moreover, it is unclear if the association between birth weight and bone mass is be mediated by body weight, lean body mass, or fat mass.Aim: We hypothesize that birth weight is associated with peak bone mass in men independent of current lean b...

Objective: To estimate the occurrence of hypopituitarism 12 months following traumatic brain injury (TBI), describe the time course, evaluate the predictive value of early hormonal changes and trauma related parameters, as well as out-come.Methods Forty-six patients with TBI (mild (GCS:13–15) n=22; moderate (GCS:9–13) n=9; severe (GCS<9) n=15) were included. Patients were tested early post-injury (baseline hormone level...
