Arteriovenöse Dissektion (AVD) bei retinalen Venolenastverschlüssen
2009
BACKGROUND: The aim of this study is to report on arteriovenous sheathotomy in branch retinal vein occlusion (BRVO) with a long-term follow-up and examine the visual field effects of this surgical approach. PATIENTS AND METHODS: In a clinical trial 36 eyes with branch retinal vein occlusion (22 eyes with ischaemia, 14 eyes with chronic macular oedema) underwent surgical decompression accompanied by peeling of the membrana limitans interna after prior isovolemic haemodilution for 3 months had been unsuccessfull. RESULTS: All eyes showed a significant reduction of macular oedema 3 months after surgery. During follow-up (median: 26.4 months) visual acuity increased in 24 / 36 eyes and was stab…
Top-cited articles in cerebrospinal fluid leak (rhinorrhea and otorrhea) (1945–2018)
2021
Abstract Introduction: As scientific knowledge has grown in biomedicine, it has also become necessary to develop tools to manage and understand the body of evidence. In that sense, bibliometrics has become a consolidated discipline for analyzing scientific activity, enabling the characterization of a particular field or area of knowledge by means of the quantification of the bibliographic characteristics of scientific publications. Objective: The objective of this study was to determine the most frequently cited articles in the field of cerebrospinal fluid rhinorrhea and otorrhea. Methods: The searches took place on the Clarivate Analytics Web of Science platform, which includes the MEDLINE…

Analyses of odontogenic tumours : the most recent classification proposed by the World Health Organization (2017)
2020
Background The fourth edition of the ‘’WHO Classification of Head and Neck Tumours’’ was published in January 2017 and includes a classification of odontogenic tumours. This review aims to examine the changes made in this new classification in comparison with the previous classification of 2005. Material and Methods An electronic search was conducted in the PubMed, Scopus and Cochrane databases with the keywords “odontogenic tumor”, “WHO classification” and “update”. Studies published from January 2009 to April 2019 with a high level of scientific evidence were included, but studies not published in English, epidemiological studies and studies with a low level of evidence were excluded. Res…
Republication de: recommandations formalisées d'experts. Prise en charge de la patiente avec une pré-éclampsie sévère–RFE communes Société française …
2022
International audience; Objective: To provide national guidelines for the management of women with severe preeclampsia. Design: A consensus committee of 26 experts was formed. A formal conflict of interest (COI) policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independently of any industrial funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. Methods: The last SFAR and CNGO…
Management options for low-dose methotrexate-induced oral ulcers : a systematic review
2019
Background Oral ulcers caused by methotrexate (MTX) at low doses are a known side effect of this drug. Although increasingly more patients are medicated with MTX, these painful ulcers, without traumatic origin and resistant to any type of treatment, are not usually identified by health professionals as a side effect of the medication. Material and Methods In the absence of a consensus protocol for the effective treatment of oral lesions produced by MTX, the objective of this article was to review and analyse the information from articles related to oral ulcers produced by low-dose MTX and to record the clinical management performed and the MTX dose given to the patient. Data sources - Medli…
High Dynamic Range Spectral Imaging Pipeline For Multispectral Filter Array Cameras
2017
Spectral filter arrays imaging exhibits a strong similarity with color filter arrays. This permits us to embed this technology in practical vision systems with little adaptation of the existing solutions. In this communication, we define an imaging pipeline that permits high dynamic range (HDR)-spectral imaging, which is extended from color filter arrays. We propose an implementation of this pipeline on a prototype sensor and evaluate the quality of our implementation results on real data with objective metrics and visual examples. We demonstrate that we reduce noise, and, in particular we solve the problem of noise generated by the lack of energy balance. Data are provided to the community…
The accuracy of calculated base excess in blood.
2002
Most equations used for calculation of the base excess (BE, mmol/l) in human blood are based on the fundamental equation derived by Siggaard-Andersen and called the Van Slyke equation: BE = Z x [[cHCO3-(P) - C7.4 HCO3-(P)] + beta x (pH -7.4)]. In simple approximation, where Z is a constant which depends only on total hemoglobin concentration (cHb, g/dl) in blood, three equations were tested: the ones proposed by Siggaard-Andersen (SA), the National Committee for Clinical Laboratory Standards (NCCLS) or Zander (ZA). They differ only slightly in the solubility factor for carbon dioxide (alphaCO2, mmol/l x mmHg) and in the apparent pK(pK'), but more significantly in the plasma bicarbonate conc…
Simulation-based education for cardiopulmonary resuscitation and airway management protocols: a brief report of a systematic review and meta-analysis.

We aimed to summarize the efficacy of simulation-based education in cardiopulmonary resuscitation and airway management [1].
Neural conservation in skull base surgery
2002
Surgical treatment of lesions of the skull base carries significant risk to the functioning of the cerebral hemispheres, brainstem, and cranial nerves. This risk is due to both (1) problems associated with maintaining an adequate blood flow while exposing and removing the tumor and (2) direct or indirect trauma to the brain, perineural tissues, and cranial nerves. These risks may be reduced if information about possible implications of surgical maneuvers on the cerebral blood flow and on the function of the patient’s CNS and cranial nerves is available and can be monitored during surgery of the skull base. The use of EMG neuromonitoring for the facial nerve and of brainstem evoked response …
