Treating Schizophrenia With the Diuretic Bumetanide: A Case Report.

Administration of the diuretic and NKCC1 chloride cotransporter antagonist bumetanide reduces the severity of autism spectrum disorders in children, and this effect is mediated by a reduction of the elevated intracellular chloride concentrations and a reinforcement of GABAergic inhibition (Lemonnier et al Transl Psychiatry. 2012;2:e202; Tyzio et al Science. 2014;343:675-679).

Potential of barrage fish ponds for the mitigation of pesticide pollution in streams.

Barrage fishponds may represent a significant surface water area in some French regions. Knowledge on their effect on water resources is therefore necessary for the development of appropriate water quality management plans at the regional scale. Although there is much information on the nutrient removal capacity of these water bodies, little attention has been paid to other agricultural contaminants such as pesticides.

Accumulation and half-lives of 13 pesticides in muscle tissue of freshwater fishes through food exposure.

Fish are often exposed to various molecules like pesticides. Some of these compounds get biomagnified within aquatic food web, inducing health hazards of consumers. However, behaviors of many pesticides are still unknown.

Pesticide pressure and fish farming in barrage pond in Northeastern France. Part II: residues of 13 pesticides in water, sediments, edible fish and their relationships.

Residues of pesticides in fish farming productions from barrage ponds are seldom studied in spite of increasing health questionings and environmental concerns. The purpose of this study is to establish the pesticide contamination profiles of sediments and edible fish from five ponds in Northeastern France. Multi-residues method and liquid chromatography-tandem mass spectrometry analysis were used to quantify 13 pesticides (azoxystrobin, carbendazim, clomazone, diflufenican, dimethachlor, fluroxypyr, iprodion, isoproturon, mesosulfuron-methyl, metazachlor, napropamid, quizalofop and thifensulfuron-methyl).

Does pet arrival trigger prosocial behaviors in individuals with autism?

Alteration of social interactions especially prosocial behaviors--an important aspect of development--is one of the characteristics of autistic disorders. Numerous strategies or therapies are used to improve communication skills or at least to reduce social impairments. Animal-assisted therapies are used widely but their relevant benefits have never been scientifically evaluated.

Pesticide pressure and fish farming in barrage pond in northeastern France. Part III: how management can affect pesticide profiles in edible fish?

Purpose: The quality of fish produced in ponds needs to be ensured. Indeed, pond is often strongly connected to an agricultural watershed, and pesticides are a main health and environmental issue of concern. In this context, the purpose of this study is to highlight the management practices which could impact the pesticide contamination profiles in edible fish and to give recommendations for better practices.

Pesticide pressure and fish farming in barrage pond in Northeastern France Part I: site characterization and water quality.

Purpose: Fish farming in barrage pond is a rearing system commonly used worldwide. Obtaining good water quality is essential to improve sustainability of these ecosystems, both for health of fish consumers and environmental considerations. However, ponds are often located in agricultural landscape, but few study reports impact of pesticide pressure on these ecosystems.

Organochlorine pesticides and polychlorinated biphenyls in sediments and fish from freshwater cultured fish ponds in different agricultural contexts in north-eastern France.

Organochlorine pesticides (HCB, HCH with α-, β-, and γ isomers, heptachlor, cis-heptachlor epoxyde, trans-heptachlor epoxyde, endosulfan with α- and β isomers, sulfate endosulfan, o,p'-DDT, p,p'-DDT, o,p'-DDE, p,p'-DDE, o,p'-DDD, p,p'-DDD, chlorothalonil, alachlor, aldrin, dieldrin, methoxychlor, oxychlordane, chlordane with α- and γ isomers, p,p'-dicofol and o,p'-dicofol) and indicators PCBs (IUPAC nos. 28, 52, 101, 118, 138, 153, and 180) were studied both in sediments and muscles of farmed fish species (Cyprinus carpio and Perca fluviatilis). Samples were collected from fish ponds located in the hydrographic basin of the Moselle River (Lorraine Region, France).

Multiresidue method for the determination of 13 pesticides in three environmental matrices: water, sediments and fish muscle.

Pesticides residues in aquatic ecosystems are an environmental concern which requires efficient analytical methods. In this study, we proposed a generic method for the quantification of 13 pesticides (azoxystrobin, clomazone, diflufenican, dimethachlor, carbendazim, iprodion, isoproturon, mesosulfuron-methyl, metazachlor, napropamid, quizalofop and thifensulfuron-methyl) in three environmental matrices. Pesticides from water were extracted using a solid phase extraction system and a single solid-liquid extraction method was optimized for sediment and fish muscle, followed by a unique analysis by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS).

Polycyclic aromatic hydrocarbons and hydroxylated metabolites in the muscle tissue of Eurasian perch (Perca fluviatilis) through dietary exposure during a 56-day period.

Eurasian perch (Perca fluviatilis) was exposed trophically to phenanthrene, pyrene and benzo[a]pyrene. Accumulation kinetics in the muscle tissue of parent PAHs and hydroxylated metabolites were established for 56 days at 3 levels of exposure (0, 100 and 500 μg/kg BW). Benzo[a]pyrene and 3-hydroxy-benzo[a]pyrene were not detected in the muscles.

Multiresidue method to quantify pesticides in fish muscle by QuEChERS-based extraction and LC-MS/MS.

Pesticide residues in fish muscle are an environmental and a health safety concern which requires analytical methods presenting high sensitivity and low limits of quantification. In this study, adapted QuEChERS method, coupled to liquid chromatography tandem mass spectrometry (Scheduled MRM-5500 QTRAP), was developed to quantify 13 pesticides (azoxystrobin, clomazone, diflufenican, dimethachlor, carbendazim, iprodion, isoproturon, mesosulfuron-methyl, metazachlor, napropamid, quizalofop and thifensulfuron-methyl) in muscle of fish. Quantification limits were below 1 ng g(-1) except for clomazone (1.

[Telepsychiatry at the service of autism].

Introduction: The authors report on the set-up of a telehealth system developed to facilitate exchanges between the Autism Resource Centre of Brittany (centre de ressources pour l'autisme [CRA]) located in Brest and an adult psychiatry structure of Vannes' Hospital in the Morbihan region, these sites are about 200 kilometres distant.

Objectives: This coordinated work using computer networks aims at sustaining the action of a unit specialised in autistic patients. The goal is to both render a precise diagnostic (teleexpertise) and favour assistance and support to residents and their families while instituting a medical education tool for the health professionals of this unit.

[Bipolar disorders in children and adolescents].

While difficult, early detection of bipolar disorders in children and adolescents is crucial. Depending on age, diagnosis may be more or less difficult. Family history and the environment must also be taken into account.

[Kleine-Levin syndrome: a case report].

The purpose of this article is to report an original clinical case whose symptoms suggest a very peculiar pathology, because of its rarity, symptomatic expression and unclear etiopathogenesis: the Kleine-Levin Syndrome (KLS). During the regression of tonsillitis concomitant with an emotional shock, the 15-year-old patient exhibited a dramatic change in behaviour, at odds with his previous state, and accompanied by hypersomnia and confusion, megaphagia, irritability, hypersexuality and mood disorders. We observed a spontaneous and total regression of the symptoms after 12 days, except for the incomplete amnesia that proved to be persistent.

[Evolution and description of a complete hospitalisation unity in child and teenager psychiatry].

The university department of child and adolescent psychiatry of Brest Hospital (a medium size town of 200,000 inhabitants) has at disposal a 14 in-patient emergency care unit, where young people under 16, mostly in crisis (individual and/or family and/or institutional crisis) are admitted. This unit opens 24h a day throughout the year, and patients with any type of pathology are admitted for a short stay, mainly with no demand for care. After a description of this unit with its modalities of functioning, the authors will report on its activity assessed from sets of data pertinent to the last 8 years.

Environmental factors influence language development in children with autism spectrum disorders.

Background: While it is clearly admitted that normal behavioural development is determined by the interplay of genetic and environmental influences, this is much less the case for psychiatric disorders for which more emphasis has been given in the past decades on biological determinism. Thus, previous studies have shown that Autistic Spectrum Disorders (ASD) were not affected by parental style. However, animal research suggests that different behavioural traits can be differentially affected by genetic/environmental factors.

[New society, new families: a new basic personality? From the neurotic to the narcissistic-hedonistic personality].

Background: In Occidental countries the frame of modern families has been reshaped, and vast economical and social changes have taken place over the last thirty years. They have been marked by the disengagement of the State in the marriage, a giant evolution in conjugality which is becoming privatized and made insecure, changes in gender relations, new motives and conditions for the arrival of the child in the couple, i.e.

What happens to children with PDD when they grow up? Prospective follow-up of 219 children from preschool age to mid-childhood.

Objective: To describe the psychological development of children with pervasive developmental disorders over a period of 3 years and to identify the factors linked to their developmental paths.

Method: The study was a collaborative and prospective follow-up study of 219 preschoolers. Retrospective data and enrollment data were collected at the beginning of the study and 3 years later.

[Consensus, hedonism: the characteristics of new family and their consequences for the development of children].

Over the last three decades, the marital family model described by Durkheim at the end of the nineteenth century has undergone numerous changes, e.g. questioning about the principle of authority, women emancipation, occurrence of the "new fathers", the growing influence of the media on the daily life of families, the less frequent and most precious child (due to the reduced number of children per family),.
