Very preterm birth: who has access to antenatal corticosteroid therapy?
2010
International audience; We describe the administration of antenatal corticosteroid therapy (ACT) for liveborn very preterm neonates in a population-based study. A total of 790 very preterm neonates (between 24 and 31 full weeks of gestation) were included in this regionally defined population of very preterm neonates in France. The main outcome measure was non-access to ACT. Data were analysed using logistic and polytomous models to control for neonatal and sociodemographic characteristics, mechanisms of very preterm birth and neonatal network organisation. As compared with level III, births in levels I-II maternity units were closely related to non-access to ACT (60.1% vs. 8.8%), but not t…
Cytosolic Ca2+ and Phosphoinositide Hydrolysis Linked to Constitutively Active α1d-Adrenoceptors in Vascular Smooth Muscle
2003
In the present study, we analyzed changes in intracellular Ca2+ levels and inositol phosphate accumulation related to a population of alpha 1d-adrenoceptors in rat aorta resembling constitutively active receptors. Following intracellular Ca2+ store depletion by noradrenaline in Ca2+-free medium and removal of the agonist, restoration of extracellular Ca2+ induced four signals: a biphasic (transient and sustained) increase in [Ca2+]i, inositol phosphate accumulation, and a contractile response in the aorta. The transient increase in Ca2+, the inositol phosphate accumulation, and the contractile response were not observed in aortae incubated with prazosin or BMY 7378 [8-[2-[4-(2-methoxyphenyl…
Ausgeprägte Virilisierung in der Postmenopause - eine Falldarstellung
2005
Severe postmenopausal virilization is a rare event in clinical practice. To evaluate ovarian or adrenal hyperandrogenism endocrine tests and imaging are useful diagnostic tools. We report a case of a postmenopausal woman with hirsutism and androgenetic alopecia. A malignant cause for the present disorder could be excluded by imaging. Selective venous sampling was administered with increased testosterone level of the right adrenal vein. Right adrenalectomy and right oophorctomy was recommended.
The Odd Sibling: Features ofβ3-Adrenoceptor Pharmacology
2014
beta(3)-Adrenoceptor agonists have recently been introduced for the treatment of overactive urinary bladder syndrome. Their target, the beta(3)-adrenoceptor, was discovered much later than beta(1)- and beta(2)-adrenoceptors and exhibits unique properties which make extrapolation of findings from the other two subtypes difficult and the beta(3)-adrenoceptor a less-understood subtype. This article discusses three aspects of beta(3)-adrenoceptor pharmacology. First, the ligand-recognition profile of beta(3)-adrenoceptors differs considerably from that of the other two subtypes, i.e., many antagonists considered as nonselective actually are beta(3)-sparing, including propranolol or nadolol. Man…

Vergleich der Wertigkeit von Magnetresonanztomographie und Computertomographie bei Patienten mit Nelson-Syndrom
1992
The hypophyses of 13 patients with Nelson syndrome following bilateral adrenalectomy were examined by MRI and CT. Diffuse enlargement of the hypophysis was demonstrated in 8 patients by CT and in 9 by MRI. Compared with CT, MRI provides better demonstration of tumour development, such as abnormal convexity of the cranial margin of the hypophysis (MRI 4/13, CT 1/13), displacement of the infundibulum (MRI 4/13, CT 0/13) or optic chiasm (MRI 2/13, CT 0/13). MRI also provides diagnostically important differentiation between scar tissue and recurrence of tumour following hypophysectomy (MRI 1/3, CT 0/3) and more accurate demonstration of infiltration of the cavernous sinus (MRI 4/13, CT 2/13). C…
The Relationship between COVID-19 and Hypothalamic-Pituitary-Adrenal Axis: A Large Spectrum from Glucocorticoid Insufficiency to Excess-The CAPISCO I…
2022
Coronavirus disease 2019 (COVID-19) is a highly heterogeneous disease regarding severity, vulnerability to infection due to comorbidities, and treatment approaches. The hypothalamic–pituitary–adrenal (HPA) axis has been identified as one of the most critical endocrine targets of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that might significantly impact outcomes after infection. Herein we review the rationale for glucocorticoid use in the setting of COVID-19 and emphasize the need to have a low index of suspicion for glucocorticoid-induced adrenal insufficiency, adjusting for the glucocorticoid formulation used, dose, treatment duration, and underlying health problems. We a…
