Filter by:Takotsubo syndrome is a condition which mimics acute myocardial infarction, and is diagnosed in 1.5% to 2.2% of patients referred to hospital with suspected acute coronary syndrome. It is also known as broken heart syndrome, takotsubo cardiomyopathy, stress cardiomyopathy and apical ballooning cardiomyopathy, among other names. The pathogenesis of this disorder is not well understood. Possible mechanisms include catecholamine excess, coronary artery spasm, microvascular dysfunction, among others. This is a multicenter, nation-wide, observational study of patients who were previously diagnosed with takotsubo syndrome. The investigators aim to use this registry to help plan and carry out further studies and to improve understanding of the pathophysiologic mechanisms of this syndrome. In addition participants will be followed for events, and to monitor quality of life and stress.
This phase I/II trial studies how well quizartinib, decitabine, and venetoclax work in treating participants with acute myeloid leukemia or high risk myelodysplastic syndrome that is untreated or has come back (relapsed). Quizartinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as decitabine and venetoclax, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving quizartinib and decitabine may work better at treating acute myeloid leukemia and myelodysplastic syndrome.
Intro: Dermatology department of Henri Mondor Hospital (Creteil, France), is a reference center for toxic bullous diseases and severe cutaneous drug reactions (Stevens-Johnson syndrome (SJS), Lyell syndrome (toxic epidermal necrolysis (TEN)), generalized bullous fixed drug reactions, AGEP, DRESS, drug induced immunoglobulin A (IgA) bullous dermatosis, and erythema multiforme). In order to conduct clinical and biological research studies in drug reactions, it is necessary for the investigator's department to implement a collection of clinical data and biological samples. Hypothesis/Objective: To collect clinical data and cutaneous and biological samples for immunological, biological and genetic studies to improve knowledge about pathophysiology of drug reactions. Method: The following samples will be performed in addition to the routine practice samples: one skin punch biopsy (6mm); 43 mL of blood; blister fluid aspiration; oral and nose mucous membrane and skin eSWABs, stool samples. These samples will be stored in a dedicated biological sampling department ("Platform of biological resources"). Conclusion: The implementation of this collection should allow us to conduct pathophysiological studies about drug reactions.
Iron chelation, mostly associated with multiple red blood cell transfusion, is relatively common in patients with hematological malignancies receiving allo-HSCT. This multicenter prospective observational study is designed to establish the impact of iron chelation on relapse after allo-HSCT in patients with acute myeloid leukemia and myelodysplastic syndrome. The investigators will compare the results obtained in the prospective study to those observed in a historical retrospective cohort of paired patients who did not receive chelation. Given our clinical experience and literature results, the investigators will evaluate the Exjade chelator. Although not demonstrated, the presence of mutations of the HFE gene could play an indirect role on leukemogenesis by promoting overload. It is therefore important to evaluate the status in this patient population.
The aim of this study is to determine the validity and reliability of the Turkish version of the Functional Shoulder Score in Turkish patients with subacromial impingement syndrome (SIS).
Limited data are available on the efficacy of beta-blocker therapy for secondary prevention in Actue Coronary Syndrome(ACS) patients. This study sought to investigate the association of beta-blocker therapy at discharge with clinical outcomes in patients with ACS after percutaneous coronary intervention (PCI).
Background: Childhood epilepsy disorders are particular frequent in the area around Mahenge, southern Tanzania and recent studies have described a novel type of epilepsy with repetitive head nodding episodes and often progressive cognitive dysfunction. Despite the disease affecting thousands in Tanzania, Uganda and South Sudan, etiology and pathogenesis of the disorder termed Nodding Syndrome (NS) is still obscure as the phenotype remains imprecisely described. Epidemiological associations with Onchocerca volvulus and Mansonella spp. were noted at different African sites and remain robust even though no evidence for the presence of O. volvulus in CSF or any previous contact with the CSF was found. Hypothesis: With regard to the complex host immune reaction to O. volvulus, the investigators hypothesize that the immune response against filariae might contribute to NS and epilepsy. The investigators further assume that specific genetic traits might play a role in the pathogenesis of NS. Aims In the present study the investigators aim to examine if and how O. volvulus and/or Mansonella spp. contribute to the pathology of NS/epilepsy and therefore intend to analyze the filarial infection and the host immune response in affected children. To identify inherited traits predisposing for epilepsy, NS or specific immune responses, a genetic workup that includes whole-exome sequencing (WES) is performed. The clinical and EEG characteristics are further defined. Cognitive impairment of people with epilepsy and NS is assessed using the Wechsler Nonverbal Scale of Ability (WNV). Study design: A cross-sectional observational (groups I-III) and a case-control (groups I-V) study recruiting in total 250 patients and controls (I: people with NS, n=50; II: people with epilepsy (PWE) and onchocerciasis, n=50; III: PWE without onchocerciasis, n=50; IV: controls with onchocerciasis but otherwise healthy, n= 50; healthy controls without evidence for onchocerciasis, n= 50) is performed to describe the clinical characteristics in children with NS/epilepsy and to evaluate differences in infection and immune response between groups, respectively. The WNV should be validated in 500 healthy controls to obtain reference data in rural Africa. Summary: In summary, the study aims to elucidate clinical characteristics and the pathogenesis of NS/epilepsy in children of southern Tanzania and role of parasitic infection as a cause for NS/epilepsy.
The purpose of the study is to investigate utility and appropriateness of treatment interventions taking into account the presumed mechanisms of two main varieties of ulnar neuropathy at the elbow (UNE). The investigators hypothesize that in patients with UNE under the humeroulnar aponeurosis (HUA) surgical HUA release (simple decompression) is superior to conservative treatment. By contrast, in patients with UNE at the retroepicondylar (RTC) groove surgical HUA release (simple decompression) should not be superior to conservative treatment.
The overlap of depression and delirium as geriatric syndromes present in elderly patients with hospital admission due to hip fracture has been previously studied. Nevertheless, the relationships between these two clinical processes and other geriatric syndromes, especially malnutrition, have not been studied. For this reason, a prospective cohort study has been designed to know the differences in the incidence of geriatric syndromes during hospital admission due to hip fracture in patients with and without risk of malnutrition.
This is an observational and prospective cohort study to examine whether the addition of IVUS plaque morphological evaluation to FFR haemodynamic assessment of non-culprit lesions in NSTEACS patients will better predict MACEs.
