Ethanol Modulates Corticotropin Releasing Hormone Release From the Rat Hypothalamus: Does Acetaldehyde Play a Role?
2010
BACKGROUND AND METHODS Ethanol (EtOH) activates hypothalamic-pituitary-adrenal (HPA) axis, resulting in adrenocorticotropin hormone, glucocorticoid release, and in modifications of the response of the axis to other stressors. The initial site of EtOH action within the HPA system seems to be the hypothalamus. Thus, to determine the mechanisms responsible for these effects, we investigated: (i) whether EtOH was able to release corticotrophic releasing hormone (CRH) from incubated hypothalamic explants; (ii) whether acetaldehyde (ACD), its first metabolite formed in the brain by catalase activity, might play a role in EtOH activity. To this aim, rat hypothalamic explants were incubated with: (…
A national cohort study on pediatric Behçet's disease: Cross-sectional data from an Italian registry
2017
Abstract Background Behçet’s disease is a rare multi-systemic inflammatory disease with unknown etiology which involves principally oral and genital mucosa, skin and eyes. Average age at onset of the disease is about 25-30 years, but it may be diagnosed before the age of 16. It is not very rare in Italy, even though there are limited data concerning epidemiology. Aim of this study is to describe the baseline data of an Italian cohort of patients with as having BD or probable BD. Methods We described the baseline data of the first national epidemiological study on children coming from 16 Italian Pediatric Rheumatologic Centers diagnosed by the treating physicians as having Behçet’s Disease. …
The glucocorticoid in acute decompensated heart failure: Dr Jekyll or Mr Hyde?
2012
Glucocorticoid administration is not recommended in patients with heart failure because of its related sodium and fluid retention. However, previous experimental and clinical studies have demonstrated that glucocorticoids can also induce a diuretic effect and improve renal function in patients with acute decompensated heart failure (ADHF) with refractory diuretic resistance. We report the case of a 65-year-old man with a known diagnosis of aortic stenosis, systolic ventricular dysfunction, and chronic obstructive pulmonary disease who was admitted for ADHF. After 3 days, during which resistance to conventional therapy was observed, intravenous methylprednisolone (60 mg/d) was added to ongoi…
Glucocorticoids mediate reduction of epithelial acetylcholine content in the airways of rats and humans
1998
The cholinergic system in rat and human airways and the effects of glucocorticoids were investigated by assay of choline acetyltransferase activity, by high-pressure liquid chromatography measurement of acetylcholine, and by anti-choline acetyltransferase immunocyto-/histochemistry. Human bronchi were obtained at surgery from patients with lung cancer. Group 1 patients did not suffer from additional lung diseases and had not been treated with glucocorticoids. Group 2 patients, who suffered in addition to lung cancer from chronic obstructive bronchitis, had been treated for at least 6 weeks before surgery with four puffs of flusinolid daily. Isolated bronchial epithelial cells as well as int…
Antidepressant-like behavioral effects of impaired cannabinoid receptor type 1 signaling coincide with exaggerated corticosterone secretion in mice.
2007
Hypothalamic-pituitary-adrenocortical (HPA) axis hyperactivity is associated with major depressive disorders, and treatment with classical antidepressants ameliorates not only psychopathological symptoms, but also the dysregulation of the HPA axis. Here, we further elucidated the role of impaired cannabinoid type 1 receptor (CB1) signaling for neuroendocrine and behavioral stress coping in the mouse forced swim test (FST). We demonstrate that the genetic inactivation of CB1 is accompanied by increased plasma corticosterone levels both under basal conditions and at different time points following exposure to the FST. The latter effect could be mimicked in C57BL/6N mice by acute, subchronic, …
17 beta-carboxamide steroids: highly effective inhibitors of the phytohaemagglutinin mediated blastogenesis of normal human peripheral lymphocytes.
1984
Several novel 17 beta-carboxamide analogues of dexamethasone were synthesized. The common precursor, 9-fluoro-16 alpha-methyl-11 beta,17-dihydroxy-3-oxo-1,4-androstadiene-17 beta-carboxylic acid, did not bind to the glucocorticoid receptors of rat liver and human spleen tumours. In addition, no inhibition of the mitogen-induced blastogenesis of cultured human peripheral lymphocytes was observed. The 17 beta-carboxamide analogues, however, bound with similar affinities to the glucocorticoid receptors of both tissues. They inhibited the mitogen-induced blastogenesis of peripheral lymphocytes, showing the same potency and same order of binding affinity as the natural glucocorticoids.
Role of high-resolution ultrasound in guiding treatment of idiopathic plantar fasciitis with minimally invasive techiniques
2007
The aim of this study was to assess the reliability of peri-fascial oedema as a sonographic criterion for selecting the most appropriate treatment (ultrasound-guided corticosteroid injection or ultrasound-guided extracorporeal shock wave therapy) of idiopathic plantar fasciitis (IPF).Sixty-four patients with a clinical diagnosis of unilateral refractory IPF, treated conservatively for at least 8 weeks, were studied with high-resolution ultrasound (HRUS). Pain intensity was evaluated with a visual analogue scale (VAS). HRUS was used to confirm IPF and identify the presence of peri-fascial oedema. Patients with an HRUS diagnosis of IPF were grouped according to the presence (A) or absence (B)…
Resistance exercise-induced hormonal responses in men, women, and pubescent boys.
2002
PULLINEN, T., A. MERO, P. HUTTUNEN, A. PAKARINEN, and P. V. KOMI. Resistance exercise-induced hormonal responses in men, women, and pubescent boys. Med. Sci. Sports Exerc., Vol. 34, No. 5, pp. 806 – 813, 2002. Purpose: This study was designed to investigate the acute plasma catecholamine (CA) response to resistance exercise and its association with serum testosterone (TES), cortisol (COR), and growth hormone (GH) concentration changes. Methods: Six men, six women, and six adolescent boys (14 0 yr) performed five sets of 10 knee extensions with 40% of one-repetition maximum followed by two sets performed to exhaustion. Arterialized venous blood was sampled before, during, and after the exerc…

Patients with complete Kawasaki disease (KD), in approximately 10–20% of cases, fail to defervesce with intravenous immunoglobulin (IVIG) infusion and acetylsalicylic acid (ASA) (1–5). Failure is u...
Scoring systems for Oral Lichen Planus used by differently experienced raters
2017
BACKGROUND: Scoring systems have been widely used to evaluate the severity and activity of oral lichen planus (OLP). The aim of the present study was to compare two existing (one modified) scoring systems in the evaluation of OLP severity and correlation with pain. Three differently experienced raters were involved. MATERIALS AND METHODS: Consecutive patients with OLP were assessed for pain using the Visual Analogue Scale and examined at 10 intraoral sites before starting (T0) and three weeks after (T1) steroid therapy (Clobetasol). Three differently experienced raters evaluated photographs using two scoring systems designated White-Erosive-Atrophic (WEA) modified from an older WEA system (…
