A cross-sectional, multicentre study of the therapeutic management of multiple sclerosis relapses in Italy.
2013
Despite the existence of therapeutic guidelines, management of multiple sclerosis relapse remains heterogeneous. Optimisation of relapse outcome demands an improved understanding of the neurologist's therapeutic attitude towards relapse management, which is the aim of this study. Neurologists from 13 multiple sclerosis centres completed a questionnaire every time they assessed multiple sclerosis relapses. The questionnaire requested a guided description of the relapse's clinical characteristics and an indication of the prescribed therapy, supported with up to 3 out of 20 suggested reasons. Over 3 months, 368 questionnaires were collected. Median percentage (%) of 21 relapses resulting in a …
Characteristics and management of primary and other immune thrombocytopenias: Spanish registry study
2017
The natural history and its modulation by treatments administered for immune thrombocytopenia (ITP) in the clinical practice remains unknown. In addition, little information is available on the characteristics and management of ITP in Spain. We conducted an observational, multicenter, registry in 70 Hematology Services from Spain between 2009 and 2011, which included children from 2 months of age and adults with primary ITP or another ITP diagnosed within the last 6 months (platelet count [PC] 484 patients were included (median [Q1, Q3] age 52 [29,74] years, 87.6% adults), 56% women, 10.5% with secondary ITP. Median (Q1, Q3) PC at diagnosis was 12 × 109/l (4, 32); 72% of patients had bleed…
SARS-CoV-2 infection associated with micturition syncope: Our experience with 4 case reports.
2020
Abstract Rationale: Syncope is described as the loss of consciousness and postural muscle tone with a short duration and fast onset. Micturition syncope can be caused by abnormal vasovagal response or by the dysfunction of the blood pressure regulating mechanism, which occurs before, during, or immediately after urination. Patient concerns: We present 4 cases of COVID-19 hospitalized in the Department of Infectious Diseases of the Academic Emergency Hospital Sibiu, Romania, cases that presented micturition syncope. Diagnoses: During hospitalization, patients confirmed with SARS-Cov-2 infection using real time reverse transcriptase-polymerase chain reaction (RT-PCR) assay, presented micturit…
Toxicological Profile of Ultrapure 2,2´,3,4,4´,5,5´-Heptachlorbiphenyl (PCB 180) in Adult Rats
2014
PCB 180 is a persistent non-dioxin-like polychlorinated biphenyl (NDL-PCB) abundantly present in food and the environment. Risk characterization of NDL-PCBs is confounded by the presence of highly potent dioxin-like impurities. We used ultrapure PCB 180 to characterize its toxicity profile in a 28-day repeat dose toxicity study in young adult rats extended to cover endocrine and behavioral effects. Using a loading dose/maintenance dose regimen, groups of 5 males and 5 females were given total doses of 0, 3, 10, 30, 100, 300, 1000 or 1700 mg PCB 180/kg body weight by gavage. Dose-responses were analyzed using benchmark dose modeling based on dose and adipose tissue PCB concentrations. Body w…
High blood pressure responders show largest increase in heartbeat perception accuracy after post-learning stress following a cardiac interoceptive le…
2020
Mental disorders with physical symptoms, e.g. somatic symptom disorder, are characterized by altered interoceptive accuracy (IAc), which can be explained by individual differences in interoceptive learning (IL). We investigated if stress facilitates IL. Seventy-three healthy participants performed a heartbeat counting task (HCT: T1) and a heartbeat perception training (HBPT). After exposure to a socially-evaluated cold pressor stress test (SECPT; n = 48) or a control condition (n = 25), two more HCTs were performed (T2: 30 min after SECPT; T3: 24 h later). After the HBPT, all participants showed an increase in IAc. We separated the stress group into high vs. low systolic blood pressures (SB…
Omalizumab reduces oral corticosteroid use in patients with severe allergic asthma: Real-life data
2010
SummaryBackgroundLong-term oral corticosteroid (OCS) therapy is associated with significant burden on patients and healthcare resources; treatments that may help reduce their use are important to improve asthma management.MethodsFrench and German clinicians prescribing omalizumab for >16 weeks to patients with severe persistent allergic asthma collected OCS use data. OCS use was recorded at baseline and at a non-specific time point beyond 16 weeks from initiation of omalizumab. The number of asthma exacerbations (FEV1 16 weeks. Of these, 166 (48.0%) were receiving maintenance OCS (France, n = 64; Germany, n = 102). Following omalizumab therapy, 84 (50.6%) patients on OCS at baseline reduced…
Blood eosinophils and treatment response in hospitalized exacerbations of chronic obstructive pulmonary disease: A case-control study
2015
Background: In outpatients with chronic obstructive pulmonary disease (COPD), blood eosinophilia is considered as a biomarker of response to systemic corticosteroid therapy. However, little is known on whether blood eosinophilia is also predictive of positive clinical outcome in severe acute exacerbations of COPD requiring hospitalization. We hypothesized that blood eosinophil-positive severe acute exacerbations of COPD differ from eosinophil-negative ones in terms of response to therapy and clinical outcomes. Methods: To test our experimental hypothesis, we retrospectively analyzed medical records of patients with COPD admitted to our ward because of severe exacerbation, over a two-year pe…
GOLD 2017 treatment pathways in ‘real life’: An analysis of the DACCORD observational study
2017
Abstract Introduction The 2017 update to the Global Initiative for Obstructive Lung Disease (GOLD) strategy document includes recommendations for treatment intensification or step-down in chronic obstructive pulmonary disease (COPD), although recognises that limited supporting information is available. DACCORD is an ongoing observational, non-interventional study, recruiting patients following COPD maintenance treatment change or initiation, a subset of whom were receiving a long-acting β2-agonist (LABA) plus a long-acting muscarinic antagonist (LAMA) fixed-dose combination (FDC) on entry. Since there were no requirements in terms of prior medication (and no washout before commencing LABA/L…
Colonization of adrenal glands and ovaries of mice by HSV-2 variants
1990
HSV-2 strain ER was shown to consist of variants with different pathogenic phenotype: Variant ER+ replicates to high titers in the adrenal glands and the ovaries but much less in the spleen; the testes were not colonized. ER+ migrates to the spinal ganglia and is highly neuroinvasive after i.p. inoculation. Variant ER- replicates 100-1,000 fold less in the adrenal glands and the ovaries, but proceeds to the spinal ganglia without invading the CNS. However, both variants are highly neuropathogenic after direct i.c. injection. We conclude that neuropathogenicity, neuroinvasiveness and the ability to replicate in the adrenal glands as well as ovaries are each determined by different sets of ge…
Chronic social defeat stress causes retinal vascular dysfunction
2021
Abstract Purpose The roles of vascular dysfunction and chronic stress have been extensively discussed in the pathophysiology of glaucoma. Our aim was to test whether chronic stress causes retinal vascular dysfunction and therewith induces retinal ganglion cells (RGCs) loss. Methods Twelve mice underwent chronic social defeat (CSD) stress, while 12 mice received control treatment only. Intraocular pressure (IOP) was measured with a rebound tonometer. Blood plasma corticosterone concentration and adrenal gland weight were used to assess stress levels. Brn-3a staining in retinas and PPD staining in optic nerve cross sections were conducted to assess the survival of RGCs and axons respectively.…
