Abstract
Disinhibition is a core symptom in behavioural variant frontotemporal dementia (bvFTD) particularly affecting the daily lives of both patients and caregivers. Yet, characterisation of inhibition disorders is still unclear and management options of these disorders are limited. Questionnaires currently used to investigate behavioural disinhibition do not differentiate between several subtypes of disinhibition, encompass observation biases and lack of ecological validity. In the present work, we explored disinhibition in an original semi-ecological situation, by distinguishing three categories of disinhibition: compulsivity, impulsivity and social disinhibition. First, we measured prevalence and frequency of these disorders in 23 bvFTD patients and 24 healthy controls (HC) in order to identify the phenotypical heterogeneity of disinhibition. Then, we examined the relationships between these metrics, the neuropsychological scores and the behavioural states to propose a more comprehensive view of these neuropsychiatric manifestations. Finally, we studied the context of occurrence of these disorders by investigating environmental factors potentially promoting or reducing them. As expected, we found that patients were more compulsive, impulsive and socially disinhibited than HC. We found that 48% of patients presented compulsivity (e.g., repetitive actions), 48% impulsivity (e.g., oral production) and 100% of the patients group showed social disinhibition (e.g., disregards for rules or investigator). Compulsivity was negatively related with emotions recognition. BvFTD patients were less active if not encouraged in an activity, and their social disinhibition decreased as activity increased. Finally, impulsivity and social disinhibition decreased when patients were asked to focus on a task. Summarising, this study underlines the importance to differentiate subtypes of disinhibition as well as the setting in which they are exhibited, and points to stimulating area for non-pharmacological management.

Abstract
BACKGROUND With recent conservative strategies, prognosis of patients with desmoid-type fibromatosis (DTF) is about function preservation. We analyzed the long-term quality of life (QoL) of pediatric patients with DTF. METHODS All French young patients (<21years) treated between 2005 and 2016 for a DTF in the EpSSG NRSTS-05 study were analyzed. A first wait-and-see strategy was recommended. Patients' QoL was analyzed with the internationally validated Child Health Questionnaire (CHQ). We focused on the relevant subscales scores: physical functioning (PF), role social limitations physical (RP), bodily pain (BP), general health perception (GH) and physical (PhS) and psychosocial (PsS) summary measures. RESULTS Among the 81 patients, 52 families answered the CHQ (median delay since diagnosis = 6.2years; min2.2-max13.3 years). Median age at diagnosis was 11.5 years. Primary site: limbs (52%), head/neck (27%), or trunk (21%). Five year-Progression Free Survival was 39.1% (95%CI: 27.7-50.5%). As initial management for these 52 patients, 30 patients were first observed (57%), 13 had surgery (25%) and 9 received chemotherapy (18%). Total burden of therapy was exclusive surgery (9pts/18%), exclusive chemotherapy (18pts/35%), surgery + chemotherapy (13pts/25%), chemotherapy + radiotherapy (1 pt), surgery + chemotherapy + radiotherapy (1 pt), wait and see (10 pt). Regarding the parent forms, patients have significant lower PF (86.0vs.96.1; p = 0.03), RP (82.0vs.93.6; p = 0.04), GH (60vs.73; p < 0.005) and PhS (46.2 vs.53; p = 0.02) scores compared to healthy population. Comparison of QoL subscales scores according to initial strategy (wait-and-see vs.surgery/chemotherapy) did not reveal any difference (PF = 87.3vs.84.9; p = 0.80/RP = 83.4vs.78.7; p = 0.72/BP = 78.9vs.78.2; p = 0.95/GH = 59.7vs60; p = 0.97). Similar results were found using the children or adult forms. CONCLUSIONS Initial wait-and-see strategy does not affect long term functional impairment.

Abstract
Introduction The present study sought to identify factors affecting mortality beyond 28 days in ischaemic stroke patients with whatever ischaemic mechanism. Patients and methods A prospective population-based registry was set up in Brest County, Brittany, France. Demographic data, clinical presentation, vascular risk factors and mortality were collected from January 2008 to December 2012. At "home without help" was used as a surrogate marker for low Rankin (0-1) at discharge from the hospital. IS was classified on the TOAST classification. Overall mortality was calculated using the Kaplan-Meier method. Multivariate analysis of mortality beyond 28 days was implemented, using a Cox model, on significant risk factors identified on univariate analysis. Results About 3024 IS cases were followed up beyond 28 days. Overall mortality beyond 28 days was 38.49% at 60 months. On multivariate analysis, age (10 years: HR = 1.84; [1.66-2.02]), coronary artery disease (HR = 1.28; [1.05-1.56]), cardiac arrhythmia (HR = 1.36; [1.11-1.67]), peripheral artery disease (HR = 1.66 [1.29-2.13]) and incomplete assessment (HR = 1.39; [1.12-1.74]) were associated with higher mortality risk, whereas female gender (HR = 0.80; [0.68-0.94]), high Glasgow Coma Scale score (GCS > 12) (HR = 0.58; [0.45-0.76]), lacunar syndrome (HR = 0.82; [0.68-0.99], being 'at home without help' (HR = 0.50; [0.41-0.59]) and negative assessment (HR = 0.75; [0.58-0.97], compared to cardioembolism) were associated with better survival probability. Discussion Initial clinical status, prior cardiovascular diseases and age was associated with more risk of death: an increment of 10 years almost doubled mortality. Women had more survival probability than men, controlling for age. Ischaemic stroke mechanisms were predictors of late 5-year mortality. Conclusion Patients with negative assessment, i.e. representing truly cryptogenic ischaemic stroke, had the best survival probability probably due to fewer atherosclerotic markers.

Abstract
Since 1994, a new prevention policy has been introduced in France. Over that period, eleven regions have conducted suicide prevention programs. It is possible today to assess the effects of these programs in retrospect. We have compared mortality data of the experimental regions to those of the other regions. We observed a significant difference in favour of the regions with suicide prevention programs. Results are discussed in relation with the achieved program content.

Abstract
The government orders of April 1996 were devoted to the second generation Regional Health Organisation Plans (SROS II) as health planning levers. One of the main issues at stake in their development was the need to favour an overall management of the regional public health priorities and to involve the system's clients in them. In order to better understand the opinions of the clients themselves and the opinions of the health planning professionals on the participation of the clients in SROS II, a national sample was selected in order to take into account the diversity of regional experiences, the different institutional linkages and the unity of both the place and the problem at hand. Two series of 42 interviews conducted at 6 month intervals were recorded and a thematic analysis according to a validated interview grid was carried out by the Analytical Laboratory for Social and Health Policy (LAPSS) at the National School of Public Health (ENSP). This survey shows that the first attempt to include the participation of the system's clients in the health planning efforts by the SROS II was appreciated and recognised as legitimate and useful, yet suffered from a lack of legibility and of a clear definition of its role. Other participation mechanisms remain to be investigated and explored as they could be enlarged in the next plan, in which the clients could become a separate entity of actors as an entirely independent group.

Abstract
This article aims to identify the optimal conditions necessary for the implementation of public health interventions. In order to approach this question, the authors relied upon a review of the health promotion literature and on three evaluation reports on the processes undertaken within the framework of French regional health programmes and their British equivalent counter-parts. Based on the synthesis of this work, the article puts forth recommendations for carrying out public health interventions at the national, regional and local level. It concludes by offering some structural proposals for improving health programme implementation.

Abstract
Lipoamide dehydrogenase or dihydrolipoamide dehydrogenase (EC 1.8.1. 4) is the E3-protein component of the mitochondrial 2-oxoacid dehydrogenase multienzyme complexes. It is also the L-protein component of the glycine decarboxylase system. Although the enzymology of this enzyme has been studied exhaustively using free lipoamide as substrate, no data are available concerning the kinetic parameters of this enzyme with its physiological substrates, the dihydrolipoyl domain of the E2 component (dihydrolipoyl acyltransferase) of the 2-oxoacid dehydrogenase multienzyme complexes or the dihydrolipoyl H-protein of the mitochondrial glycine decarboxylase. In this paper, we demonstrate that Tris(2-carboxyethyl)phosphine, a specific disulfide reducing agent, allows a continuous reduction of the lipoyl group associated with the H-protein during the course of the reaction catalysed by the L-protein. This provided a valuable new tool with which to study the catalytic properties of the lipoamide dehydrogenase. The L-protein displayed a much higher affinity for the dihydrolipoyl H-protein than for free dihydrolipoamide. The oxidation of the dihydrolipoyl H-protein was not affected by the presence of structurally related analogues (apoH-protein or octanoylated H-protein). In marked contrast, these analogues strongly and competitively inhibited the decarboxylation of the glycine molecule catalysed by the P-protein component of the glycine decarboxylase system. Small unfolded proteolytic fragments of the H-protein, containing the lipoamide moiety, displayed Km values for the L-protein close to that found for the H-protein. On the other hand, these fragments were not able to promote the decarboxylation of the glycine in the presence of the P-protein. New highly hydrophilic lipoate analogues were synthesized. All of them showed Km and kcat/Km values very close to that found for the H-protein. From our results we concluded that no structural interaction is required for the L-protein to catalyse the oxidation of the dihydrolipoyl H-protein. We discuss the possibility that one function of the H-protein is to maintain a high concentration of the hydrophobic lipoate molecules in a nonmicellar state which would be accessible to the catalytic site of the lipoamide dehydrogenase.

Abstract
The fronto-temporal flap described by Schmid and modified by Meyer is a tubular flap with an internal supraciliary pedicle which allows the transposition of the temporal skin with the addition of ear cartilage on the tip of the nose or the ala nasi. This meticulous reconstruction requires four stages which are workable under local anesthesia. Four clinical cases allow to specify the advantages and the drawbacks of this technique. They place this technique in the therapeutic possibilities between the composite grafts and various local and distant flaps.

Abstract
The dependency of elderly persons became recently an autonomous issue beside the problem of the pensions or the disability. We can explain this late apparition in the field of social policy by a strong attention paid to problems of the pensions and the lack of interest to the new concept of disability. But the main reason is the disagreement on two main questions. There is no common vision on the resources that the community must devote to help dependent people and their family. Moreover there is no agreement on the quality assurance of the services provided. The public debate for the first law was focused on the measure of the dependency and its budget. The second, in a context of growth of the number of dependent people, must integrate the need of support for an increasing number of families, and the condition for production of care of quality.

Abstract
The reconstruction of the nasal tip give difficulties. The nasal myocutaneous flap seems a good solution. We have studied twenty fresh corpses after injection of coloured latex and barium. This flap and its vascular pedicle were constant. We describe the technique. We used this flap on thirteen patients. The indications are the cutaneous lesions of the middle of the nasal tip or the nostrils. The results are excellent because this flap respects the anatomical unit of the nose. The morphological and esthetical results are excellent.

Abstract
OBJECTIVE Reconstructing a nasal tip when there is neoplastic involvement is difficult, owing to the nature of the skin, which is thick, adhesive, and not very flexible, and to the proximity of the lower rim of the nasa ala, which must be respected. Dissection of twenty injected anatomic preparations has shown the reliability of using the vascular pedicle of the musculocutaneous flap of the transverse nasalis muscle. The technique was used in ten patients with skin carcinoma of the nasal tip. Esthetic results are excellent since the nasal ala is respected. A double-flap procedure may also be used for median defects.

Abstract
The subcellular distributions of folate and folate-synthesizing enzymes were investigated in pea leaves. It was observed that the mitochondrial folate pool (approximately 400 micron) represented approximately 50% of the total pool. Furthermore, all the enzymes involved in tetrahydrofolate polyglutamate synthesis were present in the mitochondria. In marked contrast, we failed to detect any significant activity of these enzymes in chloroplasts, cytosol, and nuclei. The presence of the tetrahydrofolate synthesis pathway in mitochondria is apparently a general feature in plants since potato tuber mitochondria also contained a high folate concentration (approximately 200 micron) and all the enzymes required for tetrahydrofolate polyglutamate synthesis. The specific activities of tetrahydrofolate-synthesizing enzymes were rather low (1.5-15 nmol h-1 mg-1 matrix protein), except for dihydrofolate reductase (180-500 nmol h-1 mg-1 matrix protein). Dihydrofolate reductase was purified to homogeneity. The enzyme had a native molecular mass of approximately 140 kDa and was constituted of two identical 62-kDa subunits. Interestingly, this mitochondrial protein appeared to be a bifunctional enzyme, also supporting thymidylate synthesis. The cell distribution of thymidylate synthase was also investigated. No significant activity was observed in cell fractions other than mitochondria, indicating that plant cell mitochondria are also a major site for thymidylate synthesis.

Abstract
For various reasons, including the population policies of the former Socialist countries, abortion is much more frequent than contraception in Central and Eastern Europe. The contrary occurs in Western countries. In the current context, countries in Central and Eastern Europe should improve abortion services and this should be a priority target in their health policy. The study does not detect a clear-cut advantage as concerns substituting contraception to abortion in these countries in terms for instance of reducing maternal mortality. In fact a health policy favouring contraception instead of abortion is firstly inspired by political or ethical reasons. If implemented in Central and Eastern Europe, it would require several decades to bear evident results.

Abstract
The expression of specific calcium binding proteins is being used increasingly as a potential neuroanatomical marker for neurons with similar functions. In this study, the distribution of calbindin D28k in the superior colliculus (SC) of adult hamsters was examined by light and electron microscopy. Calbindin immunoreactivity was prominent in specific regions and laminae of the SC throughout its rostrocaudal extent, and was found to label horizontal, vertical and stellate cell types. In addition, calbindin label highlighted "bridges" of neuronal processes in the intermediate layers. The most frequent calbindin-immunoreactive profiles seen in the electron microscope were dendrites, some of which were post-synaptic to apparent retinal ganglion cell axon terminals. Labelled axons and axon terminals were less frequently encountered. There was considerable overlap between the size distribution of calbindin D28k-immunoreactive neurons and that of GABA-immunoreactive or Nissl stained neurons in the SC. However, using a double fluorescent labelling technique, and examination of the tissue with confocal laser microscopy, no neurons were observed in the hamster SC that showed immunoreactivity for both calbindin and GABA. In this regard, the SC is similar to the mammalian lateral geniculate nucleus and the pretectum, but differs from the neocortex, where calbindin and GABA are colocalized. The demonstration in the SC, as well as other parts of the nervous system, of sub-populations of neurons that contain distinct calcium-binding proteins suggests that these neurons have different functional properties. Correlative studies may clarify the relevance of these cytoplasmic components as cell markers, as well as their different patterns of association with neurotransmitters and peptides.

Abstract
A three-step protocol was devised to purify H-protein, which can be readily released as a soluble protein from pea mitochondria. After the final step of purification (anion-exchange chromatography) the native enzyme was eluted as two distinct peaks at 250 and 350 mM-KCl if the lysis buffer contained glycine. Each from exhibited an identical Mr of 15000 on SDS/PAGE and they were not distinguishable by PAGE under non-denaturating conditions. Both forms catalysed the rapid fixation of [14C]bicarbonate to the carboxy group atom of glycine during the exchange reaction, whereas the reversible exchange of electrons between NADH and lipoamide bound to the H-protein in the presence of 5,5'-dithiobis-(2-nitrobenzoic acid) was seen only with the form eluted at 350 mM-KCl. During the early steps of H-protein isolation, when P- and H-protein react together in the presence of glycine, the methylamine intermediate bound to the lipoamide of the H-protein accumulates in the medium at the expense of oxidized H-protein. Under these conditions the methylamine intermediate, which is a rather stable structure, was easily separated from the oxidized H-protein on ion-exchange chromatography. The methylamine bound to the lipoamide of the H-protein prevented the reversible exchange of electrons between NADH and lipoamide. High concentrations of glycine were required for the loading of H-protein with methylamine catalysed by a large excess of P-protein.

Abstract
Using a double fluorescence retrograde labeling procedure, the present study sought to determine the degree to which basal forebrain and mesopontine tegmental neurons have axons that innervate both the reticular thalamic nucleus and the cerebral cortex. Immunofluorescence for choline acetyltransferase, somatostatin, and the calcium-binding protein parvalbumin was also performed to elucidate the neurochemical identity of basal forebrain and mesopontine tegmental inputs to the reticular thalamic nucleus. A significant portion (10-15%) of neurons in the basal forebrain and mesopontine tegmentum that were retrogradely labeled from the reticular thalamic nucleus were also found to be retrogradely labeled from the cortex. Many of these neurons stained positively for choline acetyltransferase. Of the basal forebrain neurons retrogradely labeled from the reticular thalamic nucleus, approximately 20% were found to be immunoreactive to choline acetyltransferase, whereas none was stained for somatostatin. A larger portion (up to 50%) of the basal forebrain neurons that were retrogradely labeled from the reticular thalamic nucleus were parvalbumin-immunoreactive, and some of these were also retrogradely labeled from the cortex. These results suggest that a subpopulation of cholinergic and non-cholinergic neurons in the basal forebrain and the mesopontine tegmentum may influence simultaneously the activity of neurons in the reticular thalamic nucleus and the cerebral cortex.
