Diagnostic validity of ICDAS II, VistaProof and a combination of these two methods. An in vitro study in pre-cavitated lesions
2017
Purpose In view of the present fall in advanced cavitation lesion prevalence, diagnostic methods have been developed to assist in assessing and measuring pre-cavitation lesions. The purpose of this study was to assess the VistaProof fluorescence-based system in vitro and compare the results with those of visual examination using the ICDAS II criteria. Methods 100 permanent teeth were collected and 65 were chosen at random for this study. Two separate examiners each examined them twice, 3 weeks apart, assessing them in accordance with ICDAS II. They were subsequently examined with the VistaProof system and the images were stored in the computer program. After obtaining all these data, the te…
Second-order diagnostics for space-time point processes with application to seismic events
2008
A diagnostic method for space-time point process is introduced and used to interpret and assess the goodness of fit of particular models to real data such as the seismic ones. The proposed method is founded on the definition of a weighted process and allows to detect second-order features of data, like long-range dependence and fractal behavior, that are not accounted for by the fitted model. Applications to earthquake data are provided. Copyright © 2008 John Wiley & Sons, Ltd.
Activación plaquetaria e hipercolesterolemia en la patogenia de la trombosis venosa profunda
2006
Currently it is accepted that deep vein thrombosis is a multifactorial event in which the presence of activated platelets and also plasmatic lipids seems to play a pivotal role that it is not well established in the scientific bibliography. Due to the non consensus state about these topics between the different groups working in these aspects, the topic involving deep vein thrombosis-platelets-lipids, and also their interactions, still is an interesting area of investigation, in which it is necessary to carry out studies with the aim of establishing risk factors, initial diagnostic methods and clinical assays to probe the efficacy of new therapies.
Differences Between Conventional Anorectal Manometry and High Resolution/High Definition Anorectal Manometry
2020
The book provides a comprehensive overview of high-resolution and high-definition anorectal manometry (HRAM/HDAM), showing the possible benefits of a wider use of these techniques in clinical practice, as well as their limitations. Although these techniques provide fresh insights into anorectal function and offer a new perspective on the pathophysiologic mechanisms of many defecation disturbances, there is a need to clarify whether their use has beneficial effects on clinical management compared to conventional manometry. There is still a considerable way to go to gain the clinical diffusion of esophageal HRM, which has become the gold standard in studying esophageal motility. Indeed, many …
New diagnostic and imaging technologies in dermatology
2021
INTRODUCTION Diagnosis of dermatological disorders is primarily based on clinical examination in combination with histopathology. However, clinical findings alone may not be sufficient for accurate diagnosis and cutaneous biopsies are being associated with morbidity. OBJECTIVE The objective of this article is to review the newer technologies along with their applications, limitation and future prospectus. METHODOLOGY Comprehensive literature search was performed using electronic online databases "PubMed" and "Google Scholar". Articles published in English language were considered for the review. RESULTS In order to improve and/or widen the armamentarium in dermatologic disease diagnosis and…
Review of European and American guidelines for the diagnosis of Lyme borreliosis
2019
International audience; Lyme disease is a tick-borne bacterial disease with polymorphic clinical manifestations (cutaneous, rheumatological, and neurological). In recent years the issue of the diagnosis of this infection has been highly publicized on the Internet and other media in Europe and America. Some patients and physicians may share the perception that the diagnosis of the infection is not reliable in France. We reviewed current European and American guidelines on Lyme disease and performed a methodological evaluation of all guidelines. We retrieved 16 guidelines from seven countries. Our analysis revealed a global consensus regarding diagnosis at each stage of the infection. All gui…
Zum Problem des prätherapeutischen Staging des Carcinoma Colli Uteri
1987
In a prospective study of 20 cases, the importance of nuclear magnetic resonance as a diagnostic tool in cervix carcinoma was investigated. The results were compared with those of the Computer tomography as well as with those of the clinical examinations. The histology served as "Standard". In the evaluation of the local tumor invasion the gynecological examination appeared to be the most important. The involvement of regional lymph nodes was detected more accurately by the NMR as compared to CT. The exact clinical staging was not achieved by either method; thus these new diagnostic methods do not alter the planning and the technique of the operation.
Ultraschall und Lavage beim stumpfen Bauchtrauma polytraumatisierter Patienten
2008
The reliability of sonography and peritoneal lavage in assessing the need for immediate surgical intervention in blunt abdominal trauma was examined in a controlled prospective and retrospective study. Whereas no false results occurred using peritoneal lavage, false negative findings in sonography were 9.8% and false positive findings 3.9%. A significant difference was also found on retrospective evaluation of all cases with diagnostic peritoneal lavage (2.2% false results) and ultrasound investigations (14.9% false results). This demonstrates that sonography cannot fully replace peritoneal lavage as a diagnostic method in blunt abdominal trauma.
Cardiovascular imaging in the diagnosis and monitoring of cardiotoxicity: cardiovascular magnetic resonance and nuclear cardiology
2016
Chemotherapy-induced cardiotoxicity (CTX) is a determining factor for the quality of life and mortality of patients administered potentially cardiotoxic drugs and in long-term cancer survivors. Therefore, prevention and early detection of CTX are highly desirable, as is the exploration of alternative therapeutic strategies and/or the proposal of potentially cardioprotective treatments. In recent years, cardiovascular imaging has acquired a pivotal role in this setting. Although echocardiography remains the diagnostic method most used to monitor cancer patients, the need for more reliable, reproducible and accurate detection of early chemotherapy-induced CTX has encouraged the introduction o…
