Beware of nonconvulsive seizures in prolonged disorders of consciousness: Long-term EEG monitoring is the key.

OBJECTIVE: Evaluate the prevalence of epileptic seizures (ES) and epileptiform discharges (EDs) in patients with prolonged disorders of consciousness (DOC), and potential influence of amantadine on epilepsy. METHODS: We conducted a retrospective study in 34 patients hospitalized in a DOC care unit for prolonged DOC between 2012 and 2018, who received a long-term EEG monitoring (LTM). We reviewed the prevalence of ES, EDs and nonconvulsive seizures (NCSz), the type of DOC recovery treatment administered, and neurological outcome. RESULTS: LTM was more effective than standard EEGs in detecting EDs (32% vs 21% respectively). Moreover, 12% of the LTM showed NCSz. Among patients with EDs in LTM, 73% showed no EDs in standard EEG recordings, even when performed more than once. The presence of EDs and/or NCSz in LTM was significantly associated with the occurrence of remote clinical epileptic seizures (p = 0.017) but did not influence neurological outcome (p = 1). Amantadine was not associated with higher occurrence of EDs/NCSz or clinical seizures. CONCLUSION: In our prolonged DOC population, LTM showed more pathological results (EDs and NCSz) than standard EEGs, which was significantly associated with remote clinical seizures. SIGNIFICANCE: The use of LTM might be advised to rule out NCSz in patients with prolonged DOC.

[Perception and understanding chronic heart failure by the patient. The impact of therapeutic education on the level of knowledge of patients. About 350 cases]. / Perception et compréhension de l'insuffisance cardiaque chronique par le patient. Impact d'une formation éducative sur les connaissances des patients. Etude médico-infirmière à propos de 35 cas.

UNLABELLED: Heart failure is a severe disease with a poor prognosis despite major therapeutic progresses achieved recently. A key factor is the high number of hospitalizations for heart failure, considered as being avoidable, since they are related to a lack of adequate management of the patients. Several therapeutic education programs focused on heart failure are in progress. Even though these programs aim at making patients an active agent managing the disease, data on patient's level of knowledge and experience regarding heart failure are scarce. The aim of our study was to analyze the patient's perception of the disease and his/her practices about this disease, as well as the treatments used. METHODS: we included 350 consecutive patients and analyzed their level of knowledge and experience using a questionnaire, as well as interviews performed by nurses and physicians. This initial assessment was followed by a second assessment after an 8-hours course in 2 days, made by the multidisciplinary education team of R. Dubos hospital (including physicians, nurses, physiotherapists, dietician). RESULTS: in contrast to tests assessing the knowledge on the disease, which were in overall satisfactory, the results on the level of knowledge on treatments and heart failure pathways were poor. The courses improve significantly the level of knowledge in all domains, whatever would the age and the level of patient's demand for information be. The analysis of the patient's conception of his/her own disease reveals the lack of knowledge on the severity of heart failure. Frequently, the effect of treatments is considered as poorly efficient, and a substantial fraction of these patients have underlying depressive moods. CONCLUSION: the understanding of the level of knowledge and the perception of the patient regarding his/her disease is primordial for setting educational structures and programs. However, the patient's conception of the disease is different from care providers. It is therefore essential to assess the patient's conception by an educational diagnosis prior to implement adapted education programs, in order to improve durably the patient's knowledge, at every age.
