Abstract
INTRODUCTION Alcohol use disorder (AUD) ranks among the leading causes of decrements in disability-adjusted life-years. Long-term exposure to alcohol leads to an imbalance of activity between frontal cortical systems and the striatum, thereby enhancing impulsive behaviours and weakening inhibitory control. Alternative therapeutic approaches such as non-invasive and invasive brain stimulation have gained some momentum in the field of addictology by capitalizing on their ability to target specific anatomical structures and correct abnormalities in dysfunctional brain circuits. MATERIALS AND METHODS The current review, covers original peer-reviewed published research on the use of brain stimulation methods for the rehabilitation of AUD. A broad and systematic search was carried out on four electronic databases: NCBI PubMed, Web of Science, Handbooks and the Cochrane Library. Any original article in English or French language, without restrictions of patient age or gender, article type and publication outlet, were included in the final pool of selected studies. RESULTS The outcomes of this systematic review suggest that the dorsolateral prefrontral cortex (DLPFC) is a promising target for treating AUD with high frequency repetitive transcranial magnetic stimulation. Such effect would reduce feelings of craving by enhancing cognitive control and modulating striatal function. Existing literature also supports the notion that changes of DLPFC activity driven by transcranial direct current stimulation, could decrease alcohol craving and consumption. However, to date, no major differences have been found between the efficacy of these two non-invasive brain-stimulation approaches, which require further confirmation. In contrast, beneficial stronger evidence supports an impact of deep brain stimulation reducing craving and improving quality of life in AUD, effects that would be mediated by an impact on the nucleus accumbens, a central structure of the brain's reward circuitry. Overall, neurostimulation shows promise contributing to the treatment of AUD. Nonetheless, progress has been limited by a number of factors such as the low number of controlled randomized trials, small sample sizes, variety of stimulation parameters precluding comparability and incomplete or questionable sham-conditions. Additionally, a lack of data concerning clinical impact on the severity of AUD or craving and the short follow up periods precluding and accurate estimation of effect duration after discontinuing the treatment, has also limited the clinical relevance of final outcomes. CONCLUSION Brain stimulation remains a promising approach to contribute to AUD therapy, co-adjuvant of more conventional procedures. However, a stronger therapeutic rational based on solid physio-pathological evidence and accurate estimates of efficacy, are still required to achieve further therapeutic success and expand clinical use.

Abstract
Context In the emergency ward, where the use of ultrasound is common (including for sterile procedures), ward equipment is constantly exposed to high risks of microbiological contamination. There are no clear guidelines for disinfection control practices in emergency departments, and it is not known how emergency ward doctors follow good hygiene practices. Method A multi-centre audit was conducted in 16 emergency services from Northern France regional hospitals, in form of a questionnaire. It was proposed to all emergency ward physicians. We excluded questionnaires when physicians mentioned that they did not use ultrasound on a daily basis. The questionnaire was designed using existing hygiene and ultrasound disinfection practices guidelines from varying French medical societies. It included three different clinical scenarios: (a) ultrasound on healthy skin, (b) on injured skin, and (c) ultrasound-guided punctures. All questions were closed-ended, with only one answer corresponding to the guidelines. We then calculated compliance rates for each question, each clinical situation, and an overall compliance rate for all the questions. Results 104 questionnaires were collected, and 19 were excluded. For the 85 analysed questionnaires, the compliance rates were 60.4% 95% CI [56.4–64.7] for ultrasound on healthy skin, 70.9% 95% CI [66.3–76.1] on injured skin and 69.4% 95% CI [65.1–73.6] for ultrasound-guided punctures. The overall compliance rate for the compliance questions was 66.1% 95% CI [62.8–69.1]. Analysis of the questionnaires revealed severe asepsis errors, misuse of gel, ignorance of infection control practices to be applied in the context of ultrasound-guided puncture and exposure of the probe to body fluids. Conclusion This study details areas for quality improvement in the disinfection of emergency ultrasound scanner use. Consequently, we propose a standardized protocol based upon the recommendations used for the questionnaire drafting, with a visual focus on the low compliance points that have been revealed in this audit. This protocol has been distributed to all the medical emergency services audited and included in the emergency resident’s ultrasound learning program.

Abstract
Aim The aim of this paper is to describe the clinical features of COVID‐19‐related encephalopathy and their metabolic correlates using brain 2‐desoxy‐2‐fluoro‐D‐glucose (FDG)‐positron‐emission tomography (PET)/computed tomography (CT) imaging. Background and purpose A variety of neurological manifestations have been reported in association with COVID‐19. COVID‐19‐related encephalopathy has seldom been reported and studied. Methods We report four cases of COVID‐19‐related encephalopathy. The diagnosis was made in patients with confirmed COVID‐19 who presented with new‐onset cognitive disturbances, central focal neurological signs, or seizures. All patients underwent cognitive screening, brain magnetic resonance imaging (MRI), lumbar puncture, and brain 2‐desoxy‐2‐fluoro‐D‐glucose (FDG)‐positron‐emission tomography (PET)/computed tomography (CT) (FDG‐PET/CT). Results The four patients were aged 60 years or older, and presented with various degrees of cognitive impairment, with predominant frontal lobe impairment. Two patients presented with cerebellar syndrome, one patient had myoclonus, one had psychiatric manifestations, and one had status epilepticus. The delay between first COVID‐19 symptoms and onset of neurological symptoms was between 0 and 12 days. None of the patients had MRI features of encephalitis nor significant cerebrospinal fluid (CSF) abnormalities. SARS‐CoV‐2 RT‐PCR in the CSF was negative for all patients. All patients presented with a consistent brain FDG‐PET/CT pattern of abnormalities, namely frontal hypometabolism and cerebellar hypermetabolism. All patients improved after immunotherapy. Conclusions Despite varied clinical presentations, all patients presented with a consistent FDG‐PET pattern, which may reflect an immune mechanism.

Abstract
The use of invasive and non-invasive brain stimulation and neuromodulation technologies combined with neuroimaging approaches can help refine with causal evidence our physiopathological understanding of the Obsessive-Compulsive Disorder (OCD). Two key structures, the Orbitofrontal Cortex (OFC) and the Anterior Cingulate Cortex (ACC) have been found dysfunctional in OCD compared to healthy volunteers and on such basis have been tested as therapeutic targets for invasive and non-invasive neuromodulation therapy. Hereinafter, evidence addressing the cognitive processes subtended by to those two brain regions and their role in wider associated cortico-subcortical networks is reviewed. Very specifically, their relevance for OCD clinical features is discussed in extenso and its modulation with invasive and non-invasive focal brain stimulation such as deep brain stimulation (DBS) or transcranial magnetic Stimulation (TMS). Most importantly, this article brings new insights bridging causal evidence on the structural and functional neuroanatomy subtending OCD and novel therapeutic perspectives based on focal brain stimulation.

Abstract
BACKGROUND The Paris and Nice terrorist attacks affected a thousand of trauma victims and first-line responders. Because there were concerns that this might represent the first of several attacks, there was a need to quickly enhance the local capacities to treat a large number of individuals suffering from trauma-related disorders. Since Reconsolidation Therapy (RT) is brief, relatively easy to learn, well tolerated and effective, it appeared as the ideal first-line treatment to teach to clinicians in this context. METHODS This study protocol is a two-arm non-randomized, multicenter controlled trial, comparing RT to treatment as usual for the treatment of trauma-related disorders. RT consists of actively recalling one's traumatic event under the influence of the ß-blocker propranolol, once a week, for 10-25 min with a therapist, over 6 consecutive weeks. This protocol evaluates the feasibility, effectiveness, and cost-utility of implementing RT as part of a large multi-center (N = 400) pragmatic trial with a one-year follow-up. DISCUSSION Paris MEM is the largest trial to date assessing the efficiency of RT in the aftermath of a large-scale man-made disaster. RT could possibly reinforce the therapeutic arsenal for the treatment of patients suffering from trauma-related disorders, not only for communities in western countries but also worldwide for terror- or disaster-stricken communities.

Abstract
The purpose of our study was to report the particularities of the management of toxoplasmosis seroconversion cases occurred during the third trimester of pregnancy and diagnosed in the Institute Pasteur of Tunis. The study was conducted in the Laboratory of Parasitology-Mycology of the Institute Pasteur of Tunis between January 2005 and December 2017. A total of 27 cases of toxoplasmosis seroconversion during the third trimester were included. Prenatal diagnosis was performed in five cases. PCR was positive in one case. Pyrimethamine-sulfadoxine was prescribed in one case with positive PCR and in another case as soon as maternal infection was confirmed. Spiramycine was prescribed in 24 cases for the duration of the pregnancy. One woman did not take any treatment because seroconversion was diagnosed just before delivery. Twenty newborns had congenital toxoplasmosis: 19 cases were diagnosed by serology and one case was diagnosed after amniocentesis. Two newborns (10%) were symptomatic at birth. All the newborns had neither clinical nor radiological signs during the follow-up.

Abstract
OBJECTIVES The objectives of this study were to estimate the risk of maternal-fetal transmission of toxoplasmosis and its consequences on the fetus and to emphasize the importance of follow-up of newborns in Tunisia. PATIENTS AND METHODS It was a retrospective study of 94 cases of pergravidic toxoplasmic seroconversion who were diagnosed and followed in the Laboratory of Parasitology of Pasteur Institute of Tunis between 2005 and 2010. RESULTS In our series, amniocentesis was performed for 60 parturients. Among the amniotic fluid tested, research of toxoplasmosis DNA by PCR was positive in 12 cases (12/60, 20 %). Twenty-six cases of congenital toxoplasmosis were diagnosed with 14 postnatal cases. The rate of maternal-fetal transmission of Toxoplasma gondii was 27.6 % (26/94). This risk increases with gestational age, from 19 % at seroconversion of the 1st quarter to 29.4 % in the 2nd quarter and 44.4 % in the 3rd trimester. Monitoring of newborns with congenital toxoplasmosis showed that only 3 children were symptomatic. There were 2 cases of toxoplasmic chorioretinitis and a case of brain damage. Under serological monitoring of newborns, 21 cases were lost to follow-up and monitoring was stopped for 29 after decrease of anti-toxoplasmic IgG. DISCUSSION AND CONCLUSION The prenatal diagnosis allowed to decrease the severe forms of congenital toxoplasmosis in Tunisia. Nevertheless, it is always necessary to raise the problem of the significant number of newborn children whose follow-up is incomplete.

Abstract
We report a case of fatal congenital toxoplasmosis case in Tunis (North of Tunisia) associated with I/III recombinant genotype. The Toxoplasma gondii strain was isolated from placenta and characterized molecularly by a multilocus typing (3'SAG2, 5'SAG2, SAG3, AK69, APICO, and UPRT1) and a sulfadiazine resistance mutation analysis. The isolate was shown to be a wild drug sensitive I/III recombinant strain.

Abstract
Monthly serological screening of non immune pregnant women is recommended for prevention of congenital toxoplasmosis. However, this screening is often interrupted before delivery. We report a case of congenital toxoplasmosis following infection occurring late in pregnancy. This documented case highlights the need for a final routine serological test, 2-3 weeks post-partum for all seronegative pregnant women. In fact, the screening of congenital toxoplasmosis cases allows the early administration of specific treatment that avoids later severe complications such as chorioretinitis.

Abstract
In order to fight digestive and urinary parasitoses, a national program of surveillance has been founded. The screening of these parasitoses among the non permanent resident students in Tunisia (ENRPTS) is one of the main actions of this program. Among 2560 ENRPTS tested in the laboratory of Parasitologie of Institut Pasteur of Tunis, between 1998 and 2002, 674 were infected by parasites, which represents a global prévalence of 26.3%. The intestinal protozoa constitute the majority of parasites identified (87.4%). Entamoeba histolytica has been isolated in 89 cases, essentially from students from tropical African countries. Urinary bilharziosis has been diagnosed in 25 cases. These results confirm the utility of the control of the ENRPTS. The precocious tracking permits to avoid the introduction and the dissemination of parasites already absent or rare in our country.
