OBJECTIVE To provide information on the nature, prevalence, and severity of sleep apnea in patients with acromegaly. DESIGN Consecutive case series. SETTING Tertiary referral hospital. PATIENTS Fifty-three patients with acromegaly were consecutively referred: 33 patients were referred because of clinical suspicion of sleep apnea and 20 patients were(More)
Salivary cortisol concentration was found to be directly proportional to the serum unbound cortisol concentration both in normal men and women and in women with elevated cortisol-binding globulin (CBG). The correlation was excellent in dynamic tests of adrenal function (dexamethasone suppression, ACTH stimulation), in normals and patients with adrenal(More)
Although obstructive sleep apnea (OSA) occurs commonly in acromegaly, we have recently reported an unexpectedly high prevalence of central sleep apnea (CSA) in these patients. Acromegalic patients with CSA have increased growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels compared with their counterparts with OSA. Studies in animals, normal(More)
The inhibitory effects of the angiotensin-converting enzyme (ACE)-ANG II-angiotensin type 1 (AT₁) receptor axis on jejunal glucose uptake and the reduced expression of this system in type 1 diabetes mellitus (T1DM) have been documented previously. The ACE2-ANG-(1-7)-Mas receptor axis is thought to oppose the actions of the ACE-ANG II-AT₁ receptor axis in(More)
BACKGROUND Visceral hypersensitivity is one of the proposed underlying mechanisms in functional dyspepsia (FD). It is not clear whether visceral hypersensitivity in FD is a manifestation of a central sensitization also encompassing somatic sensitization. Transient receptor potential vanilloid-1 (TRPV(1)) pathways are involved in gastric mechanosensory(More)
To assess the degree of palliation, the associated morbidity and mortality and to compare our results with other published series, we reviewed our use of the Atkinson prosthesis in 100 consecutive patients for the palliation of unresectable oesophageal carcinoma. The group had a mean age of 71.2 +/- 2.3 years. All prostheses were placed by the pulsion(More)
It has been reported that injection of somatostatin into the brain-stem will lead to apnoea in animals. The aim of this study was to determine whether peripheral administration of octreotide, an analogue of somatostatin, could influence the control of breathing. We measured the tidal volume, respiratory rate and ventilatory response to CO2, before and after(More)
BACKGROUND Endogenous pain modulation (EPM) is central to the processing of sensory information. Visceral and somatic EPM are abnormal in irritable bowel syndrome, but have not been studied in functional dyspepsia (FD). METHODS Visceral EPM was assessed in 34 FD patients and 42 healthy controls. Gastric pain was induced with oral capsaicin and EPM was(More)
BACKGROUND   Sensory sensitization is one of the main pathophysiological hypotheses in functional gastrointestinal disorders (FGIDs). As sensitization may affect various sensory modalities, we aimed to develop a reproducible gastric pain model utilizing polymodal pathways for use in functional and other pain disorders. METHODS In this double-blind,(More)
