Filter by:Vertigo is a common complaint in the Emergency Department (ED). The differential diagnosis of central and peripheral vertigo is a difficult issue that directly affects mortality. Magnetic resonance imaging (MRI) is the preferred diagnostic tool, but may not be suitable in all patients due to logistic and economic conditions. In this study, the investigators evaluated the role of thiol/disulfide homeostasis (TDH) parameters and ischemia modified albumin (IMA) levels to assist in the value of being used instead of MRI.
In this study, a prospective, randomized and controlled clinical study would be carried out to establish Ultrasound Integrated Precision Diagnosis Technology with elastography as the core technology to evaluate renal injury and repair comprehensively and accurately, and to improve the clinical diagnosis chance of renal injury (or renal fibrosis). Combined with the dynamic changes of biomarkers (inflammatory factors, cytokines secreted by immune cells, etc.) after kidney injury, the research on the prognosis of kidney disease with ultrasound elastography technology as the core would be explored, which aims to provide a scientific basis for the application of Ultrasound Integrated Precision Diagnosis Technology.
Under-diagnosis of TB in children is a critical gap to address. The INPUT study is a multinational stepped-wedge cluster-randomized intervention study aiming to assess the effect of integrating TB services into child healthcare services on TB diagnosis capacities in children under 5 years of age.
Septic pathology is an extremely frequent reason for consultation in our emergency services, with an annual incidence of severe forms between 50 to 95 cases per 100,000 inhabitants and a constant increase estimated at 9% per year. Diagnosing these patients early and precisely is a major challenge for the clinician, as this diagnosis will lead to more or less aggressive medical management. The criteria of S.I.R.S, used to define and to sort patients in sepsis according to the old definition, were completely abandoned in the last recommendations for lack of specificity but also of sensitivity. The latest recommendations suggest using another score, the "Quick Sepsis Related Organ Failure Assesment (qSOFA) score", in order to early detect septic patients at risk of poor progress. However, the recent literature highlights a very low sensitivity of the qSOFA score for the screening of septic patients, ranging from 30 to 60% according to the studies. In addition to qSOFA, other scores are described in the literature with apparently higher sensitivity, and thus seem more suitable for our daily practice. Among them is the NEWS score or the RETTS score. Each of these scores is again based upon the values of vital signs recorded as soon as the patient arrives in the emergency department. To date, very few studies have been interested, in a prospective way, in the sensitivity and the specificity of these different scores to diagnose the "infected" patients in the emergency departments. Therefore a non-interventional, prospective, multicenter cohort study is carried out here, in order to be able to compare, on the same cohort of patients admitted into emergency services, the diagnostic performance of these different scores with respect to the presence or absence of an infection. The aim of this study is to define the best clinical score to use in emergency medicine to quickly diagnose the infected patients, and offer them the best medical care.
Optimizing the MRI protocol in acute ischemic stroke remains a challenging issue. In this field, susceptibility-weighted sequences have proved their superiority over T2. Besides the strengthened susceptibility effect, enhanced susceptibility-weighted angiography (eSWAN) sequence provides also a time-of-flight (TOF) effect, allowing the exploration of the intracranial arterial circulation. The objective of this study is to compare eSWAN and 3D TOF, considered as the reference, in the detection of arterial occlusion in acute stroke.
To investigate the Mycoplasma pneumoniae-specific circulating antibody-secreting cell (ASC) response and Mycoplasma pneumoniae-specific interferon (INF)-γ-secreting T cell response, along with polymerase chain reaction (PCR) and serology, in a cohort of children with community-acquired pneumonia (CAP) and controls.
Up to now, there is no Chinese version of fibromyalgia diagnosis criteria and severity assessment scales. The aim of this study is to translate, adapt, and validate the Chinese version of the 2011 modification of the 2010 ACR preliminary criteria for the diagnosis of fibromyalgia (2011ModCr) and 2016 ACR revisions to the 2010/2011 fibromyalgia diagnostic criteria, as well as the Fibromyalgia Impact Questionnaire (FIQ-C).
Peripheral neuropathies are diseases that affect the nervous system outside the brain and spinal cord, their prevalence is 1% in the general population, the causes are extremely varied with more than 200 identified causes; the main ones are diabetes, excessive alcohol consumption and chemotherapy. They may be sometimes disabling but generally preserve autonomy. Transthyretin amyloidosis is a rare multisystematic hereditary disease with autosomal dominant transmission. They present usually as a peripheral neuropathies (FAP). They are due to a point mutation of the transthyretin gene (chr 18q). FAP is secondary to endoneurial amyloid deposits and are characterized by a slowly progressive sensory, motor and autonomic. FAP is the most severe hereditary polyneuropathy of the adult are irreversible and fatal within 5 to 12 years from onset. Most frequent mutation of TTR gene is located on the second exon; but more than 100 mutations have been reported. Prevalence of FAP is 1 per 1 million inhabitants. They have been reported until 1990s' in four endemic areas North of Portugal, Sweden, Japan and Majorca. In these areas, diagnosis is facilitated because of the stereotypical presentation : a length-dependent polyneuropathy with predominant involvement of thermal and pain sensations and autonomic dysfunction, early onset in the third decade and a predominant Met30 TTR mutation. Positive family history is frequent 85% (one of the parents is affected). Diagnosis requires detection of TTR mutation by molecular biology (blood sample) and characterization of amyloid deposit on labial salivary gland biopsy.
This study aims to validate a new diagnostic method for quantification and monitoring of sleep bruxism.
DNA biomarkers in urine are important diagnostic and prognostic indicators for bladder cancer. Many genetic alterations have been identified in the urinary DNA. However, not all bladder tumors harbor mutations in the most commonly altered oncogenes. Thus, to reach satisfactory sensitivity and specificity a new diagnostic test should include multiple biomarkers. The investigators will conduct a prospective evaluation of a panel of mutations in urine-DNA test for the detection of urothelial bladder carcinoma in patients with gross hematuria for cystoscope.
