Neurogenic pulmonary oedema after generalized epileptic seizure
1998
The diagnosis 'tonic clonic seizure' is frequently established by emergency physicians on scene. In patients with epilepsy mortality due to accidents, asphyxia, cardiac arrhythmias or postictal neurogenic pulmonary oedema (NPO) is twice as high as in the general population. We report a case of acute pulmonary oedema after a tonic clonic seizure. Following this event, the patient developed respiratory insufficiency and evidence of pulmonary oedema not associated with the classic aetiologies of congestive heart failure, aspiration or toxic exposure. The patient survived the incident after aggressive prehospital treatment, long-term intensive care and subsequent rehabilitation. A systematic ca…
Effects of cimetidine, atropine and prostaglandin E2 on rat mucosal erosions produced by intragastric distension
1980
Abstract The effects of three typical antisecretory agents: cimetidine, atrophine and prostaglandin E2 were compared on an acute rat gastric ulcer model which consisted of perfusing the stomach continuously, at a high intraluminal pressure (120 mm H2O), with a simulated gastric juice (0.1 M HCl plus 600 mg pepsin/1). As the acid and pepsin are given exogenously the inhibitory action of the antisecretory drugs is obviated in this model. Cimetidine and atropine failed to reduce gastric erosions, whereas prostaglandin E2 markedly reduced the severity of the mucosal lesions with respect to control values. Long-term treatment with cimetidine also failed to increase the resistance of the gastric …
Cross-reactivity of a pathogenic autoantibody to a tumor antigen in GABA(A) receptor encephalitis
2021
Encephalitis associated with antibodies against the neuronal gamma-aminobutyric acid A receptor (GABA A -R) is a rare form of autoimmune encephalitis. The pathogenesis is still unknown but autoimmune mechanisms were surmised. Here we identified a strongly expanded B cell clone in the cerebrospinal fluid of a patient with GABA A -R encephalitis. We expressed the antibody produced by it and showed by enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry that it recognizes the GABA A -R. Patch-clamp recordings revealed that it tones down inhibitory synaptic transmission and causes increased excitability of hippocampal CA1 pyramidal neurons. Thus, the antibody likely contributed to…
L'ergot dépasse le seigle cet ancien compagnon de l'homme ressort les griffes
2010
National audience; L’ergot du seigle dû à Claviceps purpurea se fait remarquer en cultures de céréales en France depuis 2000, sporadiquement et avec une prévalence moindre qu’en Europe du Nord. Le facteur climatique (4 années favorables de 2000 à 2009 incluses) joue sur cette réémergence, mais aussi des évolutions de pratiques culturales : développement du nonlabour et présence accrue de graminées adventices sensibles dans les parcelles ou à proximité. Les connaissances sur la biologie de C. purpurea et les facteurs le favorisant sont rappelées. Le rôle des graminées adventices et prairiales est évoqué avec les sensibilités diverses des espèces, pouvant influencer le choix de celles à impla…

Mērķis: noskaidrot epilepsijas ārstēšanas specifiku, pielietotās diagnostikas metodes, hospitalizēto, pirmreizēji diagnosticēto, medikamentozo terapiju uzsākušo pacientu skaitu; veikt zāļu apriti 2014. - 2016.gadam Bērnu Klīniskās Universitātes slimnīcas (BKUS) pacientiem vecuma grupā no 0 līdz 18 gadiem. Metode: BKUS arhīvā pieejamo bērnu slimības karšu analīze, intervija ar BKUS neirologu un pilotpētījums, izvēloties “Vizuālā mājiena meklēšanas”, “Perceptuālās saskaņošanas”, “Šternberga skenēšanas” testus. Rezultāti: 2014. – 2016. gadam BKUS saistībā ar epileptisku lēkmi h…
Culture and Real-time Polymerase Chain reaction sensitivity in the diagnosis of invasive meningococcal disease: Does culture miss less severe cases?
2019
BackgroundInvasive meningococcal disease (IMD) is a highly lethal disease. Diagnosis is commonly performed by culture or Realtime-PCR (qPCR).AimsOur aim was to evaluate, retrospectively, whether culture positivity correlates with higher bacterial load and fatal outcome. Our secondary aim was to compare culture and qPCR sensitivity.MethodsThe National Register for Molecular Surveillance was used as data source. Cycle threshold (CT), known to be inversely correlated with bacterial load, was used to compare bacterial load in different samples.ResultsThree-hundred-thirteen patients were found positive for Neisseria meningitidis by qPCR, or culture, or both; 41 died (case fatality rate 13.1%); 1…
Re: The Clinical Impact of Bacteremia on Outcomes in Elderly Patients with Pyelonephritis or Urinary Sepsis: A Prospective Multicenter Study
2018
Background Bacteremia is common in severe urinary infections, but its influence on the outcomes is not well established. The aim of this study was to assess the association of bacteremia with outcomes in elderly patients admitted to hospital with pyelonephritis or urinary sepsis. Methods This prospective muticenter observational study was conducted at 5 Spanish hospitals. All patients aged >65 years with pyelonephritis or urinary sepsis admitted to the departments of internal medicine and with urine and blood cultures obtained at admission to hospital were eligible. Transfer to ICU, length of hospital stay, hospital mortality and all cause 30-day mortality in bacteremic and non-bacteremic g…
Bioencapsulation of living bacteria (Escherichia coli) with poly(silicate) after transformation with silicatein-α gene
2007
Bioencapsulation is an intriguing way to immobilize biological materials, including cells, in silica, metal-oxides or hybrid sol-gel polymers. Until now only the sol-gel precursor technology was utilized to immobilize bacteria or yeast cells in silica. With the discovery of silicatein, an enzyme from demosponges that catalyzes the formation of poly(silicate), it became possible to synthesize poly(silicate) under physiological (ambient) conditions. Here we show that Escherichia coli can be transformed with the silicatein gene, its expression level in the presence of isopropyl beta-D-thiogalactopyranoside (IPTG) can be efficiently intensified by co-incubation with silicic acid. This effect co…
Effects of mixed reality head-mounted glasses during 90 minutes of mental and manual tasks on cognitive and physiological functions
2018
Background We evaluated the effects of a mixed reality (MR) head-mounted deviceon some cognitiveand physiological functions during 90 min tasks in an attempt to determine their safety for workers. Methods A total of 12 volunteers performed 90-min intellectual and manual tasks with and without MR glasses. Balance, Stroop, and memory tests were conducted before, during and after these tasks. Heart rate and electromyographic activity of some muscles were recorded. A survey was used to determine subjective fatigue, pain, or discomfort. Results Balance, heart rate, rate of perceived exertion, memory, and attention were unaffected by wearing MR glasses. Electromyographic activity increased with …
Poor School Academic Performance and Benign Epilepsy with Centro-Temporal Spikes
2023
Background: Poor academic performance of students with epilepsy seems to be a multifactorial problem related to difficulties in reading, writing, math, and logic skills. Poor school and academic performances refer to learning problems in a specific academic area due to learning disorders and learning difficulties not excluding the ability to learn in a different manner during school and academic life. Sometimes, school, academic difficulties, and Rolandic epilepsy can coexist together, and there may be comorbidities. Consequently, the risk of impaired academic performance in people with epilepsy is high. Methods: This review analyzed the relationship between Benign Epilepsy with Centro-Temp…
