Based on the results of their meta-analyis buy nootropil 800 mg with visa symptoms nausea, Morency and Bujold concluded that the use of metronidazole should be avoided during the second trimester of pregnancy (17) quality nootropil 800 mg symptoms 9 days after ovulation. It is not clear why metronidazole used alone may increase the risk of early delivery but it is possible that the eradication of normal bacterial vaginal flora caused by this agent allows growth of harmful organisms, leading to ascending infection, stimulation of the inflammatory process and early delivery. Gestational exposure to metronidazole in association with other antibiotics and the risk of preterm birth In spite of the controversy regarding the use of metronidazole alone for the treatment of infections that predispose to preterm birth, the benefits of the association of this agent with other antibiotics was demonstrated during the decade of 1990. Despite these findings, which seemed to indicate a clear benefit of treating bacterial vaginosis with metronidazole in association with other antibiotics, a large systematic review conducted by Okun et al. The authors however, did not assess the benefits of metronidazole in association with other antibiotics. However, this trial was designed to evaluate the potential benefit of administering an antibiotic intervention to non-pregnant women before conception in an effort to reduce preterm delivery in the subsequent pregnancy; hence exposure did not take place during pregnancy. The lack of efficacy of treatment with metronidazole associated with other agents showed by some studies raised the question if there is an adverse interaction between the antibiotics and the physiological process inducing preterm birth, which could be responsible for the increase in the risk. Even if the reviewed evidence shows a potential benefit for the use of metronidazole in association with other antibiotics (Figure 2), caution should be exercised in prescribing metronidazole with other drugs to pregnant women solely for the purpose of preventing preterm birth. Gestational exposure to metronidazole and the risk of birth defects One of the early studies that examined whether exposure to metronidazole during pregnancy is associated with any birth defects was a retrospective cohort conducted by Scott-Gray et al. The authors analyzed outcomes of 183 pregnancies and exposure during the first and third trimesters of gestation. There was no case of birth defects in children of women exposed during the first trimester of pregnancy. A noteworthy finding of this study was a case of spontaneous abortion after exposure to the drug. Similar results were found in a cohort of 190 pregnant women followed by Robinson and Mirchandani in 1965 (27), and in a cohort study of 32 subjects conducted by Rodin and Hass in 1966 (28). Again, no cases of birth defects were detected after exposure during the first trimester of gestation. The work of Rodin and Hass (28) was the only study to have no children with birth defects in the comparison group. The first studies that pointed to a possible link between exposure to metronidazole and the risk of birth defects appeared in the decade of 1970. Any major congenital malformation was the outcome of interest in a prospective cohort study with data on 50282 pregnancies conducted by Heinonen et al. Both studies lacked statistical power and the number of exposed subjects was small. The authors assessed prescriptions filled during the first trimester of pregnancy for several antimicrobial compounds. Two cohorts of pregnant women who delivered live-born or stillborn infants were identified. The exposed cohort consisted of 1387 women who filled a prescription for metronidazole between 30 days before and 120 days after the onset of their last normal menstrual period. The unexposed cohort consisted of 1387 comparable women who did not fill a prescription for metronidazole during the same time. The use and refinement of data from administrative databases in the decade of 1990s and in the early 2000’s, was reflected by the publication of several case-control and retrospective cohort studies conducted with large number of subjects. These advancements increased statistical power to addressing rare issues such as birth defects (36). In one of such study, Czeizel and Rockenbauer conducted a case-control analysis using the Hungarian Case- Control Surveillance of Congenital Abnormalities dataset (37). However, since data on exposure was obtained by questionnaire-oriented interview, results could be subject to recall bias. Data on exposure was obtained from the pharmacoepidemiological prescription database from the North-Jutland, whereas data from birth defects was obtained from the Danish medical birth registry. The authors analyzed data of 138 prescriptions for metronidazole obtained by 124 women. The association between exposure during the first 215 trimester and the risk of birth defects was assessed by a case-cohort design. Pregnancy outcome was compared with that of women who were counseled during the same period for non-teratogenic exposure. There was no difference in the rate of major malformations between the groups (3 cases of birth defects among 190 women exposed (1.

Traitement chirurgicaux : • Ils sont indiqués dans certaines formes des vertiges itératifs ou de maladie de Ménière après échec du traitement médicamenteux. Définition Les crises épileptiques sont des manifestations cliniques paroxystiques motrices, sensitives, sensorielles ou psychiques, accompagnées ou non d’une perte de connaissance, liées à une décharge anormale, excessive et hypersynchrone d’une population plus ou moins étendue de neurones du cortex cérébral. La maladie épileptique (épilepsie) est définie par la répétition, chez un même sujet, de crises épileptiques spontanées. Le taux d’incidence, défini par la survenue d’au moins deux crises spontanées par an, est de 50/100 000 habitants. Physiopathologie et étiologie Le phénomène épileptique résulte d’un déséquilibre entre systèmes excitateurs et inhibiteurs des cellules nerveuses du système nerveux central. Les étiologies des épilepsies sont très variées et résultent de la conjonction de facteurs génétiques et acquis ( lésions cicatricielles, infectieuses, tumeurs…). Complications Le taux de mortalité chez les patients épileptiques est 2 à 3 fois supérieur à celui de la population générale. Le décès peut être en relation directe avec l’étiologie de 524 Epilepsie De L’adulte l’épilepsie ( alcoolisme, tumeur, affection dégénérative) ou survenir accidentellement au cours d’une crise ( noyades, asphyxie, traumatisme crânien…), ainsi qu’aux conséquences des traitements. Des interactions complexes entre le terrain, le syndrome épileptique et le traitement peuvent être à l’origine de complications cognitives ou comportementales. Pronostic - Les patients présentant une épilepsie nouvellement diagnostiquée peuvent en fait être divisés en quatre groupes assez rapidement identifiables. La rémission, une fois obtenue sous traitement adapté, est permanente et autorise après un certain laps de temps l’arrêt définitif des médicaments. Les divers ajustements thérapeutiques vont finalement contrôler les crises mais ne hâtent pas le rémission spontanée, qui est aléatoire. L’épilepsie est sévère en raison de sa chronicité et de sa résistance relative ou absolue au traitement, palliatif plus que curatif, typiquement conduit en polythérapie. Diagnostic Le diagnostic positif de crise épileptique doit être évoqué devant la survenue brutale et inopinée d’un évènement clinique bref, stéréotypée d’un épisode à l’autre chez un même patient. Un électroencéphalogramme et si nécessaire une imagerie cérébrale est demandé à la recherche d’une étiologie éventuelle. La démarche diagnostique comprend 3 étapes successives : Rattacher le trouble clinique à un mécanisme épileptique ( interroger le malade si au moment de la crise la conscience n’est pas altérée, dans le cas contraire interroger les témoins est impératif) - Préciser le caractère focal ou généralisé de la crise ( annexe) - Classer la maladie selon l’origine de la crise : idiopathique, symptomatique ou cryptogénique (annexe). Quels patients traités Le traitement ne doit être débuté que lorsque les crises sont certaines et que l’épilepsie est suffisamment documentée au plan clinique, neurophysiologique et neuroradiologique. Objectifs de la prise en charge Les deux impératifs du traitement antiépileptique sont le contrôle complet des crises et l’absence d’effet indésirable. Prise en charge du retentissement de l’épilepsie sur la vie quotidienne du malade.
