[Mobile child psychiatric team in French Guiana: Analyzing Amerindian teenager issues]. / Équipe mobile de pédopsychiatrie en territoire guyanais : questionnement de l'adolescent amérindien.

INTRODUCTION: Since their French naturalization in 1969, Amerindians of French Guiana have been facing a full and fast reorganization of their way of life. Teenagers, at the forefront of this cultural transition, are challenging French school institutions, as well as cultural society and care system organizations in Amazonian French remote villages. Rates of autolytic behaviors such as toxic substance abuse or suicide attempts, but mostly completed suicides, are alarming among this adolescent population. To improve care delivery to those teenagers, a mobile child psychiatric team was implemented in 2013. METHODS: We describe this device, its activities and the problematics encountered. RESULTS: This team's purpose is to lead a psychiatric evaluation of teenagers in order to determine a possible psychiatric diagnosis and elaborate a care plan. Although the results are mostly encouraging, this device seems to show some limitations: lack of time dedicated to these interventions, lack of psychiatric care available for follow-up in these villages, tremendous numbers of social distress situations implicated in psychological issues. Moreover, it appears that cultural aspects must be considered in the analysis of the Amerindian adolescent population's issues and the determination of providing care. CONCLUSION: Implementation of actions based on more educational and social levels might be a solution.

Laparoscopic Liver Resection: A South American Experience with 2887 Cases.

BACKGROUND: Laparoscopic liver resections (LLR) have been increasingly performed in recent years. Most of the available evidence, however, comes from specialized centers in Asia, Europe and USA. Data from South America are limited and based on single-center experiences. To date, no multicenter studies evaluated the results of LLR in South America. The aim of this study was to evaluate the experience and results with LLR in South American centers. METHODS: From February to November 2019, a survey about LLR was conducted in 61 hepatobiliary centers in South America, composed by 20 questions concerning demographic characteristics, surgical data, and perioperative results. RESULTS: Fifty-one (83.6%) centers from seven different countries answered the survey. A total of 2887 LLR were performed, as follows: Argentina (928), Brazil (1326), Chile (322), Colombia (210), Paraguay (9), Peru (75), and Uruguay (8). The first program began in 1997; however, the majority (60.7%) started after 2010. The percentage of LLR over open resections was 28.4% (4.4-84%). Of the total, 76.5% were minor hepatectomies and 23.5% major, including 266 right hepatectomies and 343 left hepatectomies. The conversion rate was 9.7%, overall morbidity 13%, and mortality 0.7%. CONCLUSIONS: This is the largest study assessing the dissemination and results of LLR in South America. It showed an increasing number of centers performing LLR with the promising perioperative results, aligned with other worldwide excellence centers.

Efficacy of local phytotherapy in the nonsurgical treatment of periodontal disease: A systematic review.

Herbal drugs are commonly used in the treatment of several diseases, including periodontitis. So far, no systematic review had evaluated the evidence regarding the efficacy of these agents in the treatment of periodontal disease. Therefore, the purpose of this review was to evaluate the effect of local application of phytotherapic agents as adjuncts to scaling and root planing (SRP), compared to SRP alone, on clinical parameters of chronic periodontal patients. Only randomized controlled trials of at least 3 months follow-up, of SRP alone in association with local phytotherapic agents were included. MEDLINE (PubMed), Google Scholar and LILACS databases were searched for articles published up to October 2016. Random-effects meta-analyses were conducted for clinical attachment level and probing pocket depth (PPD) change after treatment. Of 1861 papers potentially relevant, 7 were included. All studies showed that periodontal treatment in association with local phytotherapic delivery promotes a significant PPD reduction and the majority of them showed clinical attachment level gain. The local use of phytotherapy as an adjunct to SRP may promote additional benefits in PPD reduction and clinical attachment level gain. However, these results must be interpreted with caution due to the small sample size, high risk of bias and heterogeneity of the studies.

Seroprevalence of five neglected parasitic diseases among immigrants accessing five infectious and tropical diseases units in Italy: a cross-sectional study.

OBJECTIVE: This multicentre cross-sectional study aims to estimate the prevalence of five neglected tropical diseases (Chagas disease, filariasis, schistosomiasis, strongyloidiasis and toxocariasis) among immigrants accessing health care facilities in five Italian cities (Bologna, Brescia, Florence, Rome, Verona). METHODS: Individuals underwent a different set of serological tests, according to country of origin and presence of eosinophilia. Seropositive patients were treated and further followed up. RESULTS: A total of 930 adult immigrants were enrolled: 477 men (51.3%), 445 women (47.9%), eight transgender (0.8%); median age was 37.81 years (range 18-80 years). Most of them had come from the African continent (405/930, 43.5%), the rest from East Europe, South America and Asia, and 9.6% (89/930) were diagnosed with at least one of the infections under study. Seroprevalence of each specific infection varied from 3.9% (7/180) for Chagas disease to 9.7% (11/113) for toxocariasis. Seropositive people were more likely to be 35-40 years old and male, and to come from South East Asia, sub-Saharan Africa or South America. CONCLUSIONS: The results of our study confirm that neglected tropical diseases represent a substantial health problem among immigrants and highlight the need to address this emerging public health issue.

[Trauma and resilience among children 3 to 6 years old in three neighborhoods of Port-au-Prince after the 2010 earthquake in Haiti]. / Traumatismes et résiliences chez les enfants de 3 à 6ans dans trois quartiers de Port-au-Prince après le séisme de 2010 en Haïti.

The paper describes an action research for indicative assessment of psychological problems of young children following the 2010 earthquake in Haiti, and the interest of using the Creole version of the questionnaire PSYCa 3-6. The survey took place in Port-au-Prince, and the evaluators were trained to a proper standardized administration of the questionnaire. BACKGROUND: The mental health needs of young children in natural disaster contexts often remain unaddressed. The lack of a rapid and simple tool for screening combined with few mental health professionals available to accurately diagnose and provide appropriate care mean that young children remain without care. Here, we present the results of psychological screening of young children aged 3 to 6 using the questionnaire PSYCa 3-6. METHODS: This study was conducted in Port-au-Prince, Haiti. The scale was translated into Haitian Creole using corroboration of independent translations and submitted twice to the parents at home, at the end of 2011 and again at the beginning of 2013. At the first stage 166 children 3 to 6 years old were included 49 of whom were included at the second stage. The results and diagnostic properties were assessed comparing the PSYCa 3-6 to the Clinical Global Impression Severity Scale as the gold standard. RESULTS: Boys were more prone to psychological disturbances than girls. The size and position among the siblings increased the score of psychological disturbance. The neighborhood and the perception of environmental violence had a significant impact on the score of psychological disturbance. The significant improvement in scores between the two examinations showed moderate resiliency whose main factors seemed to be the social support received by the family, the rapid return to school, faith and religious practice.

The Effects of Two Different Cleaning and Disinfection Programs on Broiler Performance and Microbiological Status of Broiler Houses

The objective of this study was to investigate the influence of two cleaning and disinfection programs on broiler performance and on the microbiological status of the facilities. This trial was an observational study of comparative character. Two experiments were conducted, with 960 birds each. Both experiments were carried out in a positive-pressure broiler house. Broilers were distributed in pens equipped with a bell drinker and a tube feeder each. In the first experiment, new wood shavings were used as litter material, and in the second, reused wood shavings were used. Two treatments with16 replicates of 30 birds each were evaluated. The regular treatment consisted of dry and wet organic matter removal, followed by washing. The European treatment consisted of dry organic matter removal, humidification, washing with water under high pressure, detergent application, rinsing, and application of two combined disinfectants: glutaraldehyde 250g/L + formaldehyde 185g/L; p-chlor-m-cresol 210 g/L. Biosecurity measures were adopted during daily management tasks to prevent cross contamination between treatments. The effectiveness of the treatments was evaluated by microbiological analysis performed before and after treatment applications, as well as by broiler performance results. Live performance results were similar between both treatments when broilers were reared on new litter. When reused word-shavings were used as litter material, the European treatment promoted better broiler performance. The European treatment was more effective than the regular treatment in reducing total microbial counts in the facilities when reused wood shavings were used as litter material, and positively influenced broiler performance.

Prebiotic, probiotic and symbiotic as alternative to Antibiotics on the Performance and Immune Response of Broiler Chickens

This study aimed to evaluate diets supplemented with prebiotic, probiotic and symbiotic as an alternative to antibiotics on the performance and immune response against the virus of Newcastle disease in broiler chickens. 1,400 one-day old male Cobb 500 chicks were raised until 42 days old in a completely randomized design with 2x2+1 factorial scheme with seven replications. The treatments were: diet without supplementation (base diet - BD), BD + prebiotic, BD + probiotic, BD + symbiotic (prebiotic + probiotic), and BD + antibiotic. The parameters evaluated were performance and antibody serum titers against Newcastle disease. No antibiotic effect was observed on performance. The symbiotic provided better results for weight gain and feed:gain ratio until 21 days old than isolated additives. At 28 days old, the broilers fed diets with prebiotic presented better feed: gain ratio. In the same period (28 d-old), there was an antibody production increase against the Newcastle disease virus in the group supplemented with prebiotic. It can be concluded that the utilization of symbiotic in broiler chickens' diets can substitute performance enhancing antibiotics. The inclusion of prebiotic in the diet improves feed: gain ratio at 1-28 days old. The chickens' immune response increases at 28 days against the Newcastle disease virus in the group supplemented with prebiotic.(AU)

Liver resection for non-colorectal, non-neuroendocrine metastases: analysis of a multicenter study from Argentina.

BACKGROUND AND AIM: Resection of colorectal liver metastases has become a standard of care, although the value of this procedure in non-colorectal non-neuroendocrine (NCRNNE) metastases remains controversial and is still a matter of debate. The aim of the study was to determine the utility of liver resection in the long-term outcome of patients with NCRNNE metastases. MATERIAL AND METHODS: The records of 106 patients who underwent liver resection for NCRNNE metastases in the period 1989 to 2006 at 5 HPB Centers in Argentina were analyzed. Patient demographics, tumor characteristics, type of resection, long-term outcome and prognostic factors were analyzed. Depending on primary tumor sites, a comparative analysis of survival was performed. RESULTS: Mean age was 54 (17-76). Hepatic metastases were solitary in 62.3% and unilateral in 85.6%. Primary tumor sites: Urogenital (37.7%), sarcomas (21.7%), breast (17.9%), gastrointestinal (6.6%), melanoma (5.7%), and others (10.4%). Fifty-one major hepatectomies and 55 minor resections were performed. Twenty patients underwent synchronous resections. An R0 resection could be achieved in 89.6%. Perioperative mortality was 1.8%. Overall, 1-year, 3-year, and 5-year survival rates were 67%, 34%, and 19%, respectively. Survival was significantly longer for metastases of urogenital (p=0.0001) and breast (p=0.003) origin. Curative resections (p=0.04) and metachronous disease (p=0.0001) were predictors of better survival. CONCLUSIONS: Liver resection is an effective treatment for NCRNNE liver metastases; it gives satisfactory long-term survival especially in metachronous disease, in patients with metastases from urogenital and breast tumors and when R0 procedures can be performed.
