Published: April 2023

ABSTRACT Objective: mapping the scientific evidence about the use of educational technologies for caregivers in the context of Pediatric Oncology hospital units. Method: this is a scoping review based on the PRISMA-ScR recommendations and on the Joanna Briggs Institute methodology. The search was performed by two independent reviewers in 12 national and international data sources. Publications available in full and free of charge in electronic means were included, with no language or time restrictions. Abstracts were excluded, as well as letters to the editor, opinion articles, books, monographies, dissertations, theses, blog postings, and theoretical and reflection articles. Data analysis was descriptive, with elaboration of charts and absolute and relative frequency statistics. Results: the final sample was comprised by 15 studies published between 2010 and 2020 and mainly from developed countries. Apps and videos were the predominant educational technologies, followed by printed materials, contributing to increasing the caregivers' knowledge about the disease and cancer treatment, symptom management and side effects of the chemotherapy drugs. In addition, when compared to printed materials, the videos showed a reduction in the caregivers' anxiety levels. The professionals most involved with the technologies were nurses and physicians. Conclusion: it was possible to map that apps and videos are the main educational technologies that are being developed to instruct caregivers, addressing diagnosis and treatment of child-youth cancer, symptom management and self-care promotion.

Abstract The soymilk is a ready-to-eat, nutritious and naturally cholesterol-free product. Several soybean specialty cultivars were developed in Brazil in order to increase the human consumption of soybean products. The aim of this work was to evaluate the nutritional composition and consumer acceptance of soymilk from three soybean cultivars with special features such as high-protein and isoflavone contents, mild flavor and lipoxygenase-free compared to three conventional ones. The soymilk was obtained after blanching with a bicarbonate solution, grinding, centrifugation and pasteurization. The physicochemical and nutritional evaluation data were analyzed using Analysis of Variance (ANOVA) and Tukey’s test to check differences among means, and the consumer data through cluster analysis and internal preference mapping. The lipoxygenases were inactivated after thermal processing. There were significant differences among soybean cultivars and soymilks related to the protein, isoflavones, oil, and sugar contents and soymilk yield (p < 0.05). The BRS 133 and BRS 284 cultivars and soymilks presented the highest total isoflavone content (p < 0.05). Regarding the overall consumer acceptance, there were significant differences among cultivars (p < 0.05) with means ranging from 5.9 to 6.7 and the lower score was obtained by BRS 267. However, the cluster analysis identified three consumer segments according to preference similarity. The cultivars BRS 284 and BRS 267 reached the highest mean among the consumers of segment 1 (6.8 and 6.7 respectively). The consumers of segment 2 preferred the cultivar without lipoxygenases, BRS 213 (mean of 7.5) while segment 3 preferred the BRS 133 (mean of 7.4). The process of blanching of soybean with bicarbonate solution, grinding with boiling water and pasteurization mitigated the differences between conventional and specialty cultivars and the six cultivars evaluated were suitable for soymilk production.

Published: April 2023

ABSTRACT The aim of this study was to report the clinical case of an 8-year-old male patient seen at the Pediatric Dentistry outpatient clinic at the Universidade Federal do Paraná, Brazil, diagnosed with molar-incisor hypomineralization (MIH) after presenting with pain in teeth 16, 36, and 46, which had extensive atypical cavities and opacities on the adjacent enamel. A diagnostic wax-up of affected teeth was performed for manufacture of silicone occlusal matrix. Encapsulated high-viscosity glass ionomer cement was handled and inserted into the occlusal matrix which was fitted onto the teeth by slight finger pressure. After setting time, excess of material was removed, and occlusion was checked. A flowable resin coating material was applied, and the restorations were finished. Six months later, the restorations performed for treatment of the severe MIH lesions proved to be efficient, lowering the sensitivity reported by the patient, reshaping the teeth, improving their function, and refining dental esthetics.

ABSTRACT Objective: To evaluate the oral health and related factors among people with visual impairment in a municipality in southeastern Brazil. Methods: A cross-sectional and descriptive household study was carried out on a representative sample of people with visual impairments in a medium-sized city in Brazil. A clinical-dental examination was performed (evaluating tooth loss, caries, periodontal health, dental plaque use and need of prosthesis) and a semistructured questionnaire was applied, investigating the socioeconomic conditions (sex, age, marital status, skin color and income) and the use of dental services (reason, time since, and type of service used [private/public] in last dental visit). Descriptive and bivariate analysis were performed to asses the factors related to oral health. Results: The mean age of participants was 65 years (±15.05), with the majority women (70.9%). 53.1% of the interviewees were edentulous, but 58.2% had a good perception of oral health. The blind ones use less public services (p=0.038) and with a lower frequency (p=0.014) than subjects with low vision. Those with less schooling had higher tooth loss and lower periodontal problems (p <0.05). There was a reduction of dental plaque six months after the educational action (30.7%; p=0.01), especially among the low vision participants (p=0.01). Conclusion: Severe tooth loss and unsatisfactory hygiene contrast with self-perception of oral health. Visual acuity and schooling were related to access and oral health. Actions for promotion and equity are necessary to overcome the inequalities encountered.

Abstract Objective: To evaluate the presence of axial skeletal deviations in children and adolescents and to relate them to body mass index (BMI), age and sex. Methods: 101 patients aged 7 to 17 years old were included in this study; exclusion criteria were primary orthopedic diseases and syndromes or treatments that affect growth. Patients were grouped according to their BMI Z-score: eutrophic (n=29), overweight (n=18) and obese (n=54). They underwent static clinical inspection was made by simetrographic technique. Intermaleolar distance was obtained, Adam’s forward bend and tiptoe tests were performed. Results: When comparing obese and eutrophic patients, changes in the cervical spine (p<0.01), spine (p<0.001), hip (p<0.01) and shoulders (p<0.001) were present in more than half of the obese patients (62.5%, 62.2%, 79.9% and 55.4%, respectively). Changes in the knees were more frequent among obese (p<0.001) when compared to eutrophic patients. There was no variation regarding age or sex (p>0.05). Conclusions: being overweight influences skeletal deviations in children and adolescents.

Abstract Objective: To describe the health-related quality of life (QOL) in children with cerebral palsy (CP) associated with congenital Zika infection. Methods: Cross-sectional study of a consecutive series of children, followed in a referral multicentric rehabilitation network in Brazil. We invited the caregivers to respond to the Brazilian version of the Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM) questionnaire. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) 26.0™. We used absolute and relative frequencies for categorical variables and mean and standard deviation for continuous variables. Results: The sample consisted of 193 children, at mean age of 50.3±7.6 months. We observed a predominance of children with cerebral palsy (CP) with Gross Motor Function Classification System (GMFCS) level V (93.7%). Epilepsy (88.4%) was the most common comorbidity. CPCHILDTM mean scores were activities of daily living (ADL)/personal care 43.2±12.6; positioning, transferring and mobility 33.7±16.5; comfort and emotions 84.4±15.2; communication and social interaction (CoSI) 48.2±24.3; health 70.9±17.1; and overall quality of life (OQOL) 72.1±17.1. Total score was 54.8±11.3. Conclusions: Among children with cerebral palsy (CP) related to congenital Zika syndrome, the quality of life (QOL) scores were very similar to other populations with cerebral palsy (CP). The activities of positioning, transferring and mobility had the greatest impact on health-related quality of life (QOL). Rehabilitation strategies and public policies should prioritize aspects related to mobility for this population.

Published: April 2023

Abstract Objective: The classic triad, which defines IFAP syndrome, is ichthyosis follicularis, alopecia, and photophobia. It is a rare X-linked genetic disorder characterized by multiple congenital anomalies with variable severity, caused by pathogenic variants in the MBTPS2 gene, which encodes a zinc metalloprotease that is essential for normal development. This study aimed to report a case of a Brazilian patient with IFAP syndrome presenting skeletal anomalies, which is a rare finding among patients from different families. Case description: We describe a male proband with IFAP syndrome showing severe ichthyosis congenita, cryptorchidism, limb malformation, and comprising the BRESHECK syndrome features. Using whole-exome sequencing, we identified a rare missense variant in hemizygosity in the MBTPS2 gene, which had not been identified in other family members. Comments: This is the first diagnosis of IFAP syndrome in Brazil with a molecular investigation. The present case study thus expands our knowledge on the mutational spectrum of MBPTS2 associated with IFAP syndrome.

Published: April 2023

ABSTRACT No-till vegetable farming is a feasible alternative to reduce erosion-induced losses and to increase soil nutrient availability, because cover crop residue protects the soil and its decomposition promotes nutrient cycling, which can improve the yield of the subsequent crop. The present study assessed the production and decomposition of cover crops and the agronomic performance of broccoli grown on this residue using different nitrogen doses in a no-till system. A randomized block design was used, in a split-split plot arrangement of main plots (cover crops), sub-plots (N doses) and sub-sub plots (decomposition times), with four repetitions. Seven cover crops were studied, as follows: [1) signal grass (SG); 2) sunn hemp (SH); 3) pearl millet (PM): 4) SG+SH; 5) SG+PM; 6) SH+PM and 7) SG+SH+PM]; in addition to four doses of nitrogen topdressing [T1) no N application (control); T2) 60 kg/ha N; T3) 90 kg/ha N and T4) 120 kg/ha N]; and five cover crop residue decomposition times: zero (cutting), 15, 30, 60 and 90 days after transplanting (DAT) the broccoli seedlings. Cover crop dry weight (DW) production, residue decomposition, and the head fresh (HFW) and dry weight (HDW) and yield (YLD) of broccoli were assessed. Among the cover crops, sunn hemp and the intercropped SG+SH treatment exhibited the lowest DW production and, along with signal grass, the shortest half-life (T½) and highest residue decomposition rate. The best-performing broccoli plants were those grown using PM, SH and a combination of both as cover crops. The highest broccoli production was obtained using sunn hemp residue, regardless of nitrogen topdressing, with HFW of 788 g/plant and YLD of 30 t/ha.

Published: April 2023

ABSTRACT Desiccating herbicides can promote uniformity of maturation, and early harvest and provide improvements in the physical, physiological, and sanitary seeds quality. The objective of this work was to evaluate the use of herbicides in early harvest and in the physiological quality of chickpea seeds. The experimental design was of randomized blocks with four replications, considering a complete factorial design with one control (no application) + two factors (four herbicides x three different doses): glufosinate-ammonium (200, 400 and 500 g a.i./ha); diquat (200, 400 and 500 g a.i./ha); carfentrazoneethyl (15, 30 and 37.5 g a.i./ha) and saflufenacil (49, 98 and 122.5 g a.i./ha). Saflufenacil (49 g a.i./ha) showed the lowest harvest anticipation (4 days) and a low percentage of vigor (50.25%). Glufosinate (400 g a.i./ha), was the most promising as it increased germination to 83.75% and vigor to 78.25%, in addition to promoting the anticipation of harvest by up to 17 days, while the normal cycle of the crop, observed in the control, was 154 days.
Mathematical modeling, mediator-guiding teacher, and constructivism: discursive interlacements in the constitution of the teaching figure
Authors: Cambi Betina , Caldeira Ademir Donizeti
Published: April 2023

ABSTRACT The purpose of this article is to discuss the few conditions that made it possible for the emergence of the statement “the teacher, while developing Modeling activities, is no longer the transmitter but a mediator-mentor in the process of teaching” in the field of Mathematical Modeling from the perspective of Mathematical Education. We make use of the concepts, discourse, enunciate and statement from Michel Foucault's line of thought. The analytical material from which the aforementioned enunciate emerged encompasses theses and dissertations defended in the period between 1987 and 2016, which report, describe, or discuss the development of Modeling activities in the classroom of basic education. The analysis made it evident that the constructivist discourse did not consist only of a possibility for the emergence of the statement mediator-teacher, but also of the crystallization of this teaching representation as a pedagogic truth in the field of Mathematical Modeling.

Published: April 2023

RESUMO A argamassa estabilizada tem como característica o tempo de pega estendido. O emprego de aditivos incorporadores de ar e estabilizadores de hidratação são fundamentais para manter o estado fresco da argamassa em obra e com trabalhabilidade adequada. Esse trabalho analisou a influência combinada desses aditivos, com o objetivo de contribuir com a dosagem de argamassas. Foram ensaiadas nove formulações, as quais variaram o teor de aditivos, entre o máximo e o mínimo recomendado pelo fabricante. Os ensaios no estado fresco foram: índice de consistência, densidade de massa e teor de ar incorporado e Squeeze-flow; e no estado endurecido para: resistência à tração na flexão e à compressão e resistência de aderência à tração. Verificou-se a eficiência dos aditivos em manter as propriedades reológicas das argamassas, mantendo-as trabalháveis, porém também se identificou perda das propriedades mecânicas no estado sólido, devido a problemas de hidratação decorrente do excesso de aditivo estabilizador de hidratação e pela formação de vazios pelo uso de incorporador de ar. Dessa forma, conclui-se sobre a importância da compatibilização entre os aditivos em conjunto e o controle tecnológico na dosagem das argamassas, para que elas se mantenham trabalháveis sem perder as propriedades mecânicas necessárias para um bom desempenho e durabilidade.
In the palimpsest of the classroom: the legitimation of disputed literary works at school
Authors: Amparo Patrícia Aparecida do
Published: April 2023

Abstract This article presents some results of research seeking to understand the disputes for the legitimate reading of literary works in daily school life. Based on it, it was understood that reading gains meanings in the fabric of daily life as the actions of teachers and students reveal socially structured points of view on the issue, frequently questioning the school imperatives. To this end, in dialogue with authors such as Pierre Bourdieu and Roger Chartier, class observations were carried out in three Portuguese-speaking high school classes, two of which in the regular modality and one in Young Adults Education (EJA), whose records originated the Field Diaries. Thus, the investigation uses the resources of school ethnography. Semi-structured interviews with two teachers and eight students, teenagers and adults, also make up the research material. Thus, the objective was to understand the tensions related to legitimate culture within a level of education that has been going through various processes of expansion and questioning of its formative meanings. The analysis of sources allows us to see reading as an element that supports and structures a relevant dimension of school life, while its meanings are constructed according to the logic of everyday interactions that help in the classification and identification of legitimate practices. It was possible to describe classrooms in the image of the palimpsest, in which the reading references of students and teachers occupy a marginal space but put pressure on the activities and literary dispositions offered to students.
Preconceptions of science shared by students from a public rural school in Brazi
Authors: Sousa Rosielson Soares de , Silva Wagner Rodrigues , Brito Cristiane Carvalho de Paula
Published: April 2023

Abstract This article aims at discussing discursive representations of science shared by students from a 7th-grade class at a rural school in the Northern Region of Brazil. The research draws on discourse perspectives of language and Applied Linguistics-oriented science education studies based on theoretical assumptions of science teaching and literacy studies. Data consist of semi-structured interviews with nine students, all of which were transcribed and organised into discursive sequences pointing to enunciative patterns. Their utterances evoke two major discourses: a “dominant science discourse”, which represents science practices associated with the natural sciences and excludes the social sciences and language studies; and a “copying discourse”, which relates to typical school tasks, such as research tasks that assume students’ learning through information copying. The present analyses contribute to challenging naturalised discourses about science in basic education and eventually to fostering science education for and amongst the social actors at school. A critical approach to teaching (one based on various research practices) can help students find meaning in the instructional contents addressed in the various curricular activities.

Abstract Assessment of fish health is one of the efforts of farmers in minimizing losses due to disease. Rapid tests on fish health can be done through blood observations. This study aimed to determine the blood glucose profile of koi carp due to ectoparasite infestation from the level of blood glucose. The results showed that reported parasites from Blitar’s koi carp were Trichodina, Dactylogyrus, Gyrodactylus, Myxobolus, Thelohanellus, Ichthyophthirius, and Argulus. Trichodina showed the highest prevalence (100%) in this case while Thelohanellus was the highest intensity level (93.8±16.3). The results of blood glucose level measurement based on parasite infestation levels showed no significant difference (p>0.05) though the health problems caused by parasites in light, medium or heavy infestation. This research also indicated that the blood glucose profile could be used as a rapid method to detect fish health caused by parasites. We suggest that other variables such as nutritional status, life stage or feeding must be conducted to ensure the glucose role in parasite identification as a rapid method for the future work.

Published: April 2023

Perovskite solar cells (PSC) have attracted considerable attention recently due to their high energy conversion efficiency, low price, simple manufacturing process, with a conversion efficiency raised from 3.8% to 25.5%, and thus are a promising new generation photovoltaic technology. This article discusses the development of device structure, the creation of material deposition techniques, including complex device engineering strategies aimed at enhancing controls over the morphology, crystallinity, composition, as well as interface properties of perovskite thin films. This article is a comparative analysis of PSC, namely lead and lead-free PSC, in order to determine which PSC is more efficient and environmentally benign. We compared two types of perovskite solar cells: CH3NH3PbI3 and CH3NH3PbI3-xClx which are lead-based perovskite solar cells versus Cs2TiBr6 and MASnI3 which are lead-free perovskite solar cells.
Engineers in Medicine: Foster Innovation by Traversing Boundaries

Published: April 2023

Engineers play a critical role in the advancement of biomedical science and the development of diagnostic and therapeutic technologies for human well-being. The complexity of medical problems requires the synthesis of diverse knowledge systems and clinical experiences to develop solutions. Therefore, engineers in the healthcare and biomedical industries are interdisciplinary by nature to innovate technical tools in sophisticated clinical settings. In academia, engineering is usually divided into disciplines with dominant characteristics. Since biomedical engineering has been established as an independent curriculum, the term "biomedical engineers" often refers to the population from a specific discipline. In fact, engineers who contribute to medical and healthcare innovations cover a broad range of engineering majors, including electrical engineering, mechanical engineering, chemical engineering, industrial engineering, and computer sciences. This paper provides a comprehensive review of the contributions of different engineering professions to the development of innovative biomedical solutions. We use the term "engineers in medicine" to refer to all talents who integrate the body of engineering knowledge and biological sciences to advance healthcare systems.

Authors: Rinchen Namgay , Nidup Tshering
Published: April 2023

Altitudinal gradient influences plant and pollinator diversity in mountain ecosystems. Small home gardens in these ecosystems are highly dependent on pollinators for fruit-vegetable production. The study evaluated the change in fruit-vegetable diversity, their pollinator species richness, abundance, crop yield and, income in the home gardens along the altitudinal gradient. Correlation between pollinator species diversity, abundance and species of fruit-vegetables and yield were studied and statistically tested for their significance. The study recorded 25 species of pollinators belonging to Vespidae, Syrphidae, Apidae, Andrenidae, Colletidae, Ichneumonidae and Scoliidae. 12 species of fruit vegetables were recorded from Cucurbitaceae, Solanaceae, Fabaceae, Brassicaceae and Lamiaceae. Correspondingly, the pollinator and vegetable species richness were found to decrease with increasing altitude, with significant negative correlation. As with increasing altitude, the vegetable yield was found to decrease significantly, affected by the decreasing pollinators. Income from the fruit-vegetables were lower at places with low diversity (i.e., higher altitudes), which is influenced by decreased yield. The fruit-vegetable and pollinator species richness and abundance, fruit set, yield and income decreased with increasing altitude, having a significant negative correlation.

Published: April 2023

Fruit set in the orchids in the wild in Bhutan seems to be generally higher than in surrounding countries in Asia. To obtain more knowledge on local pollinators in Bhutan, pollinators were photographed in the private Orchidarium, over a period of six years. A total of 10 insect species, belonging to the orders of Diptera (true flies), Hymenoptera (ants, bees, wasps) and Coleoptera (beetle), were seen pollinating the flowers of 15 different orchid species (14 epiphytic and 1 terrestrial). Several pollinators are reported for the first time as the pollinators of orchids. Our study provides a first glimpse into the pollination biology of Bhutanese orchids and could be used for the reintroduction of the locally extinct orchid pollinators elsewhere in Asia.

Fungal pathogens are most common plant pathogen of ornamental plants, reducing their aesthetic and ornamental value. Thus, the study was conducted for the diagnosis of diseases and to maintain the aesthetic value of the ornamental plants in the college campus. The fungal diseases in the campus were studied through symptomatic and microscopic studies, using micrometry for conidial size measurement. A total of 15 fungal pathogens were observed causing 4 different types of diseases on 13 ornamental plant species. Fungal leaf spot caused by Alternaria sp., Cercospora sp., Cladosporium magnoliigena, Diplocarpon rosae, Pestalotiopsis sp., Phyllosticta sp. and Didymella curtisii were observed on 8 host species followed by powdery mildew caused by Erysiphe communis, Golovinomyces cichoracearum, Oidium jasmini, Podosphaera pannosa on 5 host. Black sooty mold (Capnodium sp.) and rust (Puccinia pelargonii-zonalis) were observed on corresponding plant host. This report acquaints ornamental growers and others with general symptoms of ornamental plant diseases and possible fungal pathogens commonly observed in the campus.
Total Factor Productivity and Sources of Long-Term Growth in the Bhutanese Rice Production
Authors: Karma Yoezer
Published: April 2023

Sustainable growth in domestic food production cannot just depend on mobilizing its factor resources but will also require higher productivity growth. This paper aims to study the total factor productivity (TFP) of rice in Bhutan for the period 2009-2010 to 2016-2017. The study employs non-parametric Malmquist index approach to measure TFP growth and decompose into efficiency and technical change. In addition, panel data model is applied to determine the factors influencing changes in TFP growth. The results show that average annual Malmquist productivity growth was only slightly positive, mainly propelled by technological change. The analysis of the factors determining TFP changes suggested that irrigation and population are the key to sustaining long-term rice TFP growth.

au Liban a été relevée quotidiennement sur fichier Excel de juin à septembre 2007. Tous les patients se présentant au
poste médical ou aux dispensaires étaient inclus de manière exhaustive, qu’ils soient militaires français ou non.
Résultats : 2001 consultations ont été réalisées dont 57 % d’aide médicale à la population. Toutes les classes d’âges
étaient concernées. Les spécialités les plus fréquentes étaient la traumatologie (dont les plaies : 15,2 %, les entorses :
5,9 %, les brûlures : 2,7 %), la pathologie infectieuse (dont les diarrhées : 7,4 %, les infections ORL et des voies aériennes
supérieures : 8,3 %), et la dermatologie (dont les mycoses : 5,5 %). Les pathologies dentaires représentaient 35 % des
évacuations sanitaires, ce qui posait le problème de la mise en condition dentaire avant le départ en opération extérieure.
Parmi les motifs de consultation, seuls 7 % faisaient l’objet d’une déclaration à la surveillance épidémiologique.
Les nouveaux défis de l’eau en opérations extérieures

Les actions entreprises sur les théâtres opérationnels en vue de mettre en place une logistique de l’eau conforme aux
principes définis récemment par l’État-major des armées amènent une remise en cause d’habitudes anciennes dans ce
domaine, avec d’importantes évolutions en ce qui concerne les choix technologiques pour le traitement et la distribution
des eaux. L’expérience acquise en 2010 au Liban, dans le cadre de l’opération « Daman », permet d’identifier les
principales difficultés rencontrées dans cette démarche. Le choix raisonné des moyens de production et de distribution
des eaux destinées à la consommation humaine à partir d’un forage ont exigé la mise en œuvre de procédés techniques
complexes mais, grâce à cette approche, c’est la perspective d’un abandon du recours systématique aux eaux
embouteillées qui se dessine. La tendance à la sophistication croissante des systèmes de potabilisation des eaux, conçus
sur la base de technologies souvent nouvelles pour les armées, implique l’acquisition de compétences nouvelles par les
opérateurs en charge de ces équipements. La surveillance des processus, pierre angulaire de la stratégie de sécurité
sanitaire, devient plus contraignante et impose une utilisation rigoureuse de différents matériels de mesure. La question
de la compétence des intervenants militaires appelle donc des réponses concrètes afin d’éviter une sous-traitance
systématique qui rendrait les forces tributaires de prestataires civils. Pour le Service de santé des armées, il importe de
conserver une capacité d’expertise spécialisée de haut niveau dans le domaine de la technologie des eaux afin de pouvoir
accompagner efficacement l’ensemble des évolutions.
La légionellose et sa prévention au sein du ministère de la Défense

Décrite pour la première fois en 1976, la légionellose est désormais connue comme une maladie associée à divers types
d’installations techniques susceptibles de générer des aérosols à partir d’eaux chaudes, principalement les douches et les
tours aéroréfrigérantes. Bactéries communes de l’environnement, les légionelles présentent en effet, une adaptation à la
vie dans le milieu hydrique principalement lorsque la température est comprise entre +25 °C et +45 °C. Elles constituent
chez l’homme des agents d’infections à dominante pulmonaire, dont la létalité est élevée, observées principalement chez
des patients présentant des facteurs de risque tels qu’une immunodéficience ou une insuffisance respiratoire chronique,
des sujets alcoolo-tabagiques et des personnes âgées. Au sein du ministère de la Défense, il est recensé en moyenne
moins de trois cas de légionellose par an. Placée, dans les armées, sous la responsabilité du commandement et encadrée
par une réglementation très contraignante, la prévention de cette maladie repose sur une approche d’entretien et de
pilotage des installations techniques à risque. La température constitue le paramètre clé, pour ce qui concerne les eaux
chaudes sanitaires. En vue de contenir la colonisation des réseaux par les légionelles, il importe de maintenir la
température des eaux à des valeurs supérieures à +50 °C. Le recours à des agents désinfectants peut aussi s’avérer utile.
Dans le cas des tours aéroréfrigérantes, il est impossible d’intervenir sur la température des eaux. De ce fait, la prévention
repose sur le recours à des traitements chimiques pour désinfecter régulièrement les circuits de distribution d’eau mais
aussi toutes les surfaces en contact avec l’eau. Par ailleurs, des dispositifs permettent de limiter la formation d’aérosols.
Spice : un nouvel enjeu de santé publique?

Des cannabinoïdes de synthèse, intégrés dans des mélanges d’herbes, sont vendus sur internet sous forme d’encens à
brûler. La dénomination fréquemment retrouvée pour ces mélanges à fumer est spice. Ils contiennent des substances plus
puissantes que le Δ9 tétrahydrocannabinol, reconnu comme l’agent psychoactif du cannabis. Malgré la classification de
ces composés comme stupéfiants par la France en 2009, le phénomène « spice » continue de se développer. Les noms et
les emballages de ces produits se sont diversifiés et les composés psycho-actifs sont modifiés en réponse aux mesures de
répression. À l’heure actuelle, aucune technique rapide ne permet leur dépistage en routine au laboratoire ou dans les
centres médicaux des armées.

Le coup de chaleur d’exercice est un accident non exceptionnel dans les armées : son incidence annuelle est de 100 cas.
La mortalité en a fortement diminué grâce à une meilleure connaissance par les praticiens, la formation des personnels de terrain et une prise en charge adaptée. Toutefois, même si elles sont rares, les séquelles peuvent être invalidantes.
Nous rapportons l’observation d’un sujet de haut niveau intellectuel et qui garde des séquelles neurocognitives invalidantes plusieurs années après un coup de chaleur d’exercice sévère. Les données cliniques et l’étude de la littérature conduisent à discuter l’origine cérébelleuse de ces troubles cognitifs.

Le syndrome du cimeterre ou syndrome veinolobaire de FELSON est une pathologie rare congénitale caractérisée par un
retour veineux pulmonaire partiel ou total, situé le plus souvent dans la veine cave inférieur. Nous rapportons le cas d’un
engagé volontaire, âgé de 22 ans, chez lequel le diagnostic a été suspecté sur une radiographie thoracique. Le diagnostic
de certitude a été confirmé par une étude tomodensitométrique qui mettait en évidence la structure vasculaire aberrante
responsable d’un drainage du sang veineux pulmonaire. Cette pathologie est le plus souvent asymptomatique, comme
c’était le cas chez notre patient. Les patients symptomatiques souffrent d’un shunt gauche-droit marqué ainsi que
d’anomalies cardiaques congénitales associées. Malgré l’absence de symptômes évidents et un bilan para-clinique normal
à l’exception d’une dilatation modérée des cavités droites, notre patient a été classé inapte à servir dans les armées.
Mode d’entrée dans une schizophrénie : illustration en milieu militaire
Authors: AUXÉMÉRY Y. , BABAI J. , CARNIO C. , FIDELLE G.
Published: April 2023

Dans le cas d’une schizophrénie débutante à mécanisme d’entrée progressif, un patient peut rester sans soin, dissocié et
délirant à bas bruit pendant plusieurs semaines, voire plusieurs mois, avant que la pathologie ne soit reconnue. Ce temps
de latence diagnostique est problématique car certains sujets en souffrance tardent à bénéficier d'un traitement adapté ce
qui grève de manière importante le pronostic de l’affection. Le médecin généraliste de l’unité est en première ligne dans
cette phase de détection précoce : la mise en évidence de symptômes prodromiques et psychotiques repose exclusivement
sur l'entretien clinique. Nous nous proposons dans ce travail de décrire les indices d’alerte qui ont été utiles au médecin
d’unité pour reconnaître précocement l’entrée d’un patient militaire dans la maladie schizophrénique. La population
étudiée intéresse trente sujets militaires âgés de 19 à 30 ans recrutés sur cinq années consécutives, adressés par les
médecins d’unité au service de psychiatrie d’un hôpital d’instruction des armées pour orientation thérapeutique devant
une schizophrénie débutante. Il s’agit principalement de jeunes patients célibataires âgés de 22 à 26 ans présentant des
antécédents psychiatriques personnels ou familiaux. Militaires du rang en majorité, ils intègrent plus souvent une unité
opérationnelle de l’armée de Terre. La décompensation survient régulièrement dans les deux premières années
d’engagement, parfois en lien avec une opération extérieure récente. Les signes prodromiques d’alerte sont dominés par
les troubles du comportement, les premiers à être remarqués devant les manifestations délirantes et les éléments
dépressifs. Lors de l’entrée dans la phase psychotique, les symptômes positifs sont les plus faciles à repérer et sont
surtout dominés par les troubles du cours de la pensée et de la logique (hermétisme, bizarrerie, rationalisme morbide…)
ainsi que par les idées délirantes de persécution. Plusieurs formes cliniques d'entrée dans la maladie schizophrénique
ont été décrites dans ce travail, ce qui illustre la richesse des tableaux psychopathologiques rencontrés mais également
la difficulté d'un tel repérage.

Le spondylolisthésis par lyse isthmique bilatérale est recherché de manière systématique pour déterminer l’aptitude à
certains emplois qui peuvent majorer le glissement antérieur. Son diagnostic est radiologique et la décision médicomilitaire
concernant l’aptitude se base sur l’interprétation des clichés standards par le radiologue. La méthode de
Meyerding est la plus fréquemment employée pour évaluer et suivre le glissement. Elle diffère de celle utilisée dans les
armées françaises, pouvant alors poser de délicats problèmes de catégorisation.

Published: April 2023

La connaissance du recours aux moyens hospitaliers français est un outil majeur pour le Service de santé des armées dans
l’évaluation de son plan spécifique hospitalier, tout particulièrement dans le cadre de la construction du parcours de
soins, qui en est un élément clé. À partir des informations de l’assurance maladie, la description des prises en charge des
militaires d’active au sein des établissements de santé en 2009 a été réalisée. Les forfaits, les groupes homogènes de
séjours et les disciplines médico-tarifaires servant à la facturation hospitalière ont été analysés. La prise en compte de
l’âge, du sexe, de la durée de séjour et de la nature de la prise en charge ont complété ces données. Le non recours aux
établissements hospitaliers militaires a été estimé. En 2009, 55 278 militaires d’active ont été pris en charge dans un
établissement de santé. Le nombre de séjours, avec ou sans hébergement, était de 50 637, pour un total de 151 538
journées. Parmi ces séjours 1 667 concernaient une affection présumée imputable au service. Les hôpitaux d’instruction
des armées ont pris en charge 9 518 séjours. Les endoscopies digestives (573) sont le principal groupe de planification
pour lequel les militaires étaient hospitalisés en dehors d’un hôpital d’instruction des armées. L’étude des bases de
données médico-administratives est un apport essentiel dans la décision pour l’offre de soins.
