De la spécificité des disciplines aux pratiques enseignantes et à la formation : quelques réflexions pour les mathématiques et les sciences
Authors: Munier Valérie , Proulx Jérôme 
Published: June 2024

This article addresses questions relative to teachers of mathematics and sciences. We first establish the notion of the specificity of both disciplines as an epistemological background to underpin our ways of tackling questions about teachers’ practices, knowledge and training initiatives. Addressing issues about practices (of teachers and of teacher education) in relation to each disciplines’ specificity invites taking into account the nature of scientific and mathematical activity in itself. These orientations lead to consider the possibilities, in contrast to prescriptions, for adressing issues of teachers’ knowledge and practices, and their implications for teacher education practices.
La propriété et les propriétés dans l’officine de l’historien
Authors: Grossi Paolo 
Published: June 2024

Prenant son point de départ dans un titre d’un rapport du civiliste Pugliatti sur la propriété et les propriétés, l’article propose avec l’emploi du pluriel de relativiser la conception absolutiste de la propriété qui a triomphé au xixe siècle. L’expérience médiévale est celle d’un autre rapport de l’homme aux choses, fondé sur la possession et l’exploitation de la terre, et conduisant à envisager une pluralité de propriétés sur le même bien. Apparue au Haut Moyen Âge cette superposition de propriétés a été théorisée, avec la redécouverte des compilations de Justinien, à travers la notion de domaine utile et la théorie du domaine divisé. Bien que reposant sur une contradiction dans les termes mêmes de dominium utile, cette construction des juristes s’est ancrée dans les mentalités pendant des siècles. Trouvant ses origines dans les réflexions des théologiens et des philosophes depuis le xive siècle, la nouvelle conception anthropologique du rapport du sujet aux choses a donné naissance à l’individualisme possessif et à la propriété ‘moderne’.
Un droit sans État
Authors: Grossi Paolo 
Published: June 2024

Ce texte de Paolo Grossi invite les spécialistes d’histoire du droit du Moyen Âge à se débarrasser de deux notions qu’il considère comme « encombrantes » et profondément étrangères à l’expérience juridique médiévale, à savoir les notions de « souveraineté » et d’« État ». Pour cela, Grossi oppose un modèle unitaire moderne, où l’État souverain est la seule instance légitime à légiférer et à façonner le juridique, à un modèle pluraliste médiéval caractérisé par une grande variété de sources, d’instances et de communautés autorisées à produire du droit. Grossi met en avant l’intérêt analytique de la notion d’« autonomie » pour comprendre la pluralité des ordres juridiques du Moyen Âge ; il en ressort l’idée d’un « droit sans État », fondamentalement arrimé au monde social et qui l’exprime dans toutes ses dimensions. L’article propose ainsi une relecture radicale de la pensée politique et juridique médiévale.
Pluralité des sources et actuation de la Constitution
Authors: Grossi Paolo 
Published: June 2024

Dans ce texte – version écrite d’une leçon tenue en 2019 à l’École Nationale de Magistrature italienne – Paolo Grossi s’interroge d’abord sur la « juridicité » de la Constitution ainsi que sur les rapports entre République et État, soulignant l’âme multi-ordonnant de la Constitution italienne. Paolo Grossi invite à prendre conscience que vivre, aujourd’hui, la dimension constitutionnelle de la République signifie respecter le pluralisme juridique qui lui est propre. C’est pour cela que Paolo Grossi prône le passage « de la loi à l’interprétation », possible aussi grâce au secours épistémologique de celle que l’auteur appelle la « révolution herméneutique ». Il s’interroge enfin sur deux questions fondamentales dans cette perspective : quoi faire de la « soumission du juge à la loi » ? Et de la prétendue séparation des pouvoirs ?
Pourquoi former des « non-qualifiés » ? Le cas des agents d’entretien et des aides à domicile
Authors: Burie Adèle , Devetter François-Xavier , Valentin Julie 
Published: June 2024

Les métiers dont une fraction de l’activité relève du nettoyage constituent une part importante des métiers considérés comme peu qualifiés. Pourtant, bien que rares, des politiques en termes de formation professionnelle sont mises en œuvre. Cet article se centre sur les agents d’entretien et les aides à domicile pour dresser un bilan du rapport à la formation dans ces secteurs, d’un point de vue quantitatif et qualitatif. Il propose une analyse des motivations avancées par les employeurs, en distinguant les logiques de préparation des salariés à l’emploi et celles, plus ambitieuses, qui permettent de repenser le travail et les parcours professionnels. Il révèle les conditions requises pour que se déploie cette seconde approche de la formation : la reconnaissance sociale des compétences mobilisées et l’identification d’un employeur qui assume ses fonctions.
Panorama de la non-qualification : un manque de perspectives professionnelles quand le travail est peu qualifié
Authors: Lambert Marion , Marion-Vernoux Isabelle 
Published: June 2024

Ce travail statistique met au jour la diversité des formes de non-qualification, combinaison des caractéristiques des personnes, de leur emploi et du travail qu’elles exercent. Le troisième registre, celui du travail, caractérise à la fois le contenu de celui-ci et les conditions dans lesquelles il s’exerce. L’article présente une méthodologie pour en délimiter le périmètre à la croisée des caractéristiques des contextes organisationnels et des activités de travail des salariés. La prise en compte de cette dimension permet de montrer que bien que diplômés et mieux rémunérés, 14 % des salariés se trouvent dans une situation de non-qualification « masquée ». En effet, cette catégorie de salariés peu ciblée par les politiques publiques, évolue pourtant dans un contexte peu propice au développement des apprentissages ne permettant pas de satisfaire leurs besoins en compétences pour évoluer favorablement sur le marché du travail.
Quand l’humanitaire reproduit de profondes inégalités de carrière
Authors: Mba Jean Émile , Keuya Éveline , Beaulieu Janyck 
Published: June 2024

Cet article aborde la question des inégalités de carrière des agent·es d’entretien qui occupent une position peu qualifiée au sein des organisations humanitaires internationales au Cameroun. Il soulève une problématique novatrice qui s’intéresse à l’analyse de ces inégalités dans un champ qui pourtant prône l’égalité, l’équité et le développement humain. Mobilisant des théories éthiques du care et de la segmentation du marché du travail, il montre comment ces agent·es, en particulier les femmes, sont victimes de fortes inégalités de carrière, à la fois en raison des normes genrées associées au travail de soin, ainsi que du caractère hybride de leur métier : entre un travail domestique et un service d’entretien des bureaux. Cette hybridation s’accompagne de limitations d’accès à la formation et à la mobilité professionnelle, elles-mêmes adossées au faible niveau d’éducation de ce personnel d’entretien dans un secteur humanitaire devenu très professionnalisé.
Bilateral Persistent Sciatic Artery – An Infrequent Occurrence: A Case Report with Review of Literature
Authors: Nirhale Dakshayani Satish , Ramya Vajja , Wante Mahendra , Premchand Kalari , Burra Anoop , Bandla Vijetha , Arigela Abhinav 
Published: June 2024

Abstract
A persistent sciatic artery (PSA) is a rare congenital vascular anomaly with an extremely low incidence of about 0.04%–0.06%. It is due to the persistence of the embryological axial limb artery, representing a continuation of the internal iliac artery into the thigh through the greater sciatic foramen below the piriformis muscle and down the thigh alongside the sciatic nerve. In normal embryologic development of the lower limb, the axial artery normally regresses after week 12. Persistent sciatic artery is often asymptomatic until a complication develops, it can be classified into two types, complete and incomplete. PSA can cause serious lower limb complications such as acute or critical limb ischemia.

Abstract

Background:
Understanding the impact of malnutrition on innate immune response in Plasmodium falciparum (Pf)-infected subjects is critical for malaria control.

Aims and Objectives:
This study aims to investigate the nutritional status and innate immune response of Pf-infected subjects in Lagos, Nigeria.

Materials and Methods:
A total of 1183 patients with a history of fever or axillary temperature ≥37°C were screened microscopically for Pf at Ijede General Hospital, Lagos, Nigeria. Malnutrition was determined according to the U.S National Center for Health Statistics (NCHS) as stunting, wasting, or underweight when the Z-score is <−2 in the participants aged <20 years. Serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), and IL-12 were determined by capture ELISA while hematological parameters were measured using an automated hematology system.

Results:
A total of 384 volunteers were positive for Pf, of which 114 were <20 years with a median age of 10 years. Overall malaria prevalence was 20.89%. The malnutrition rate was 89.5%; 24 (21.05%) were stunted, 30 (26.32%) were underweight, and 48 (42.11%) were wasted. Pro-inflammatory cytokine responses were not affected by the type of malaria. TNF-α was higher in participants <5 years (P = 0.001) and in malnourished patients (P < 0.05).

Conclusion:
Together, it could be deduced that nutritional status influences Plasmodium falciparum malaria outcomes and progression pattern.
Unraveling the Enigma of Dental Caries through Conventional Analysis using Finger Print Forensics among the Students of Nadiad City, Gujarat
Authors: Mehta Rina Girish , Patel Bhupesh , Kamlesh B Rami , Patel Hiren 
Published: June 2024

Introduction:
There is growing interest in identifying genetic predispositions to dental caries using non-invasive tools. Dermatoglyphics, examining dermal ridge patterns on the hands and feet, is linked to genetic foundations. Galton’s theory asserts fingerprint constancy. In dentistry, dermatoglyphics gains attention for its correlation with students pathologies. This study evaluates the association of dental caries in students with dermatoglyphics.

Materials and Methods:
The research at the Department of Oral and Maxillofacial Pathology, Dharmsinh Desai University, involved 50 subjects (28 females and 22 males) with normal fingerprints. Ethical clearance was obtained from the institute’s Ethics Committee. Fingerprints were recorded using the conventional method, employing ink, paper, roller, glass slab and sponging pad. The prints were examined, classified and analysed through the Cummins method, categorising them into whorls, loops and arches. The dental caries were assessed through the decayed, missing and filled teeth (DMFT) scores of the participants. The DMFT score was tested for association and difference according to the type of fingerprint pattern.

Results:
Females commonly exhibit loop patterns, while males show an equal distribution between loops and whorls. The connection between fingerprint patterns and DMFT scores is notable. A Chi-square test for left-side patterns (Chi-square = 27.74, P = 0.002) reveals a strong association, linking specific patterns to distinct DMFT scores. Similarly, for right-side patterns (Chi-square = 11.349, P = 0.045), there is significance, emphasising the relationship between fingerprint types and dental caries.

Conclusion:
The study examined the connection between fingerprint patterns and dental caries in children, discovering a positive correlation. Specific patterns such as arch, loop and whorl were linked to caries presence or absence, suggesting their potential as an early detection tool, although accuracy might vary based on genetic factors.
Dental Erosive Wear Assessment amongst Different Age Groups Utilising Basic Erosive Wear Examination: An Epidemiological Study
Authors: Verma Anirudh , Prasad D Krishna 
Published: June 2024

Introduction:
The study aims to assess the prevalence of erosive tooth wear and risk levels amongst different age groups utilising Basic Erosive Wear Examination (BEWE) amongst the population of South West Coastal India.

Materials and Methods:
One hundred and sixty healthy people participated in the research (n = 32 per group). Using sextants and the BEWE, index (0–18) allowed for the evaluation of erosive tooth wear. Questionnaires supplemented clinical data. Each participant was assigned to groups based on the severity of their erosive wear: high (BEWE sum ≥ 14), moderate (BEWE sum 9–13), low (3–8) and none (0–2).

Results:
There is no significant difference in the degree of erosive tooth wear across different age groups (χ2– 20.11, P – 0.067 [not-significant]). There is a significant difference in response to questions across different age groups (χ2 – 487.21, P – 0.01 [significant]).

Conclusion:
The prevalence of erosive tooth wear grows as individuals age. Older age groups, patients who are at a higher risk level require a more comprehensive form of treatment. The aetiology of dental erosion remained unknown to the patients, indicating a deficiency in their understanding of erosive tooth wear.
Evaluation of aloe vera gel as a local drug delivery agent in the treatment of chronic periodontitis: A clinical and microbiological study
Authors: Marella Yamuna , Dhulipalla Ravindranath , Chandu Viswa Chaitanya , Adurty Chaitanya , Kolaparthy Lakshmikanth , Nagamani Penupothu 
Published: June 2024

Abstract

Background:
Local delivery of antibacterial agents into periodontal pockets provides a multitude of benefits over systemic antimicrobials resulting in the increased preference for such use among periodontal health-care providers.

Aim:
The study aims to determine the antimicrobial efficacy of adjunctive use of the herbal extract “aloe vera gel” (Aloe vera (L.) Burm. f.) along with scaling and root planing (SRP) in patients with chronic periodontitis.

Materials and methods:
This prospective, single-blind randomized split-mouth clinical trial was done among 22 subjects diagnosed with chronic periodontitis. Periodontal parameters and mean log counts of porphyromonas gingivalis (P. gingivalis) evaluated using real-time polymerase chain reaction were recorded. SRP was performed both at control and test sites. The evaluation of clinical and microbiological parameters was done at baseline and 3 months’ post-intervention. Data were analyzed using Statistical Package for Social Sciences (SPSS) V.20 software.

Results:
While significant improvement in both clinical and microbiological parameters from baseline to three months was observed in both the test and control sites, the mean reduction in plaque index, periodontal pocket depth, and mean log colony-forming unit counts of P. gingivalis were significantly higher in the test sites compared to the control sites.

Conclusion:
The results of this study reject the null hypothesis in favor of the alternative hypothesis that adjunctive application of locally delivered aloe vera gel for the treatment of chronic periodontitis enhances the beneficial effects of mechanical therapy.
Efficiency of Jatamansi (Nardostachys Jatamansi [D. Don] DC.) and selected Yoga module in test anxiety of school-going children: A single-arm clinical trial
Authors: Arabi Fasnath , Jithesh M. , Shobhana M. C. 
Published: June 2024

Abstract

Introduction:
Test anxiety (TA) is a form of social evaluation anxiety experienced by individuals in a setting of assessment. Studies among students have reported an anxiety rate of 10%–30% which affects their overall performance. On analyzing the symptoms of TA, it is found that, there is a predominance of imbalance of Vata and Pitta humor. Jatamansi (Nardostachys Jatamansi [D. Don] DC.) has the property to balance all three Sharira Dosha (body humor) along with Manasa Dosha (psychic humor) and is hence widely used in psychiatric conditions. Several studies concluded that Yoga therapy is effective in various anxiety conditions.

Aim:
As the reported trials are less in TA from the Ayurvedic fraternity, this study aimed to evaluate the effect of Jatamansi and Yoga in test anxiety (TA) of school-going children.

Materials and methods:
Four hundred higher secondary students with age group 15-17 Yrs. were screened with TA self-assessment questionnaire after the quarterly examination. The 32 students satisfying the criteria and with informed assent, were selected for intervention, 45 days before the half-yearly examination. Jatamansi tablet was administered to the participants at the dose of two tablets (each of 500 mg) twice daily at 7 am and 7 pm with lukewarm water along with practicing 50 min of the selected Yoga module in the morning, continuously for 1 month. Assessments were done by the Westside TA scale (WSTAS) and Suinn TA behavior scale (STABS) before and after the intervention and after the half-yearly examination. The data were analyzed using paired “t-test.”

Results:
The total score of the WSTAS showed a statistically significant effect at the level of P < 0.001, which is suggestive of improvement in the wandering of mind, improving confidence, and concentration ability during the examination. Similarly, the total score of the STABS showed a statistically significant effect at the level of P < 0.001 suggesting improvement in anxious behavior during the examination. The scale showed highly significant results in anxiety at the level of P < 0.001 during preparation and after completing the examinations and at the level of P < 0.05. The drug does not show any drug tolerance or adverse drug reaction.

Conclusion:
The study concluded that there is a significant role for the Jatamansi tablet 500 mg twice daily along with a selected Yoga module for one month in reducing the test anxiety (TA) of school-going children.

Published: June 2024

Abstract
Chemical leukoderma is an acquired depigmentary skin disorder, caused by repeated exposure to specific chemical compounds or secondarily to allergic contact dermatitis or through direct toxic effects, sharing similar clinical and histological features with vitiligo. We report a case of widespread allergic contact dermatitis with chemical leukoderma which later became a persistent light reactor.
Role of Multidetector Computed Tomography with Contrast in Evaluation of Congenital Lung Malformations in Pediatric Age Group at a Tertiary Care Hospital: An Observational Study
Authors: Sravya K. , Madhuri Sarukolla Meena , Veena M. , Vanaja B. , Bajaj Sunitha , Kumari Vijaya 
Published: June 2024

Background:
Computed tomography (CT) has a larger role in the noninvasive examination of congenital lung abnormalities, thanks to the introduction of multidetector CT (MDCT). If a surgical lesion is suspected, it is often necessary to use cross-sectional imaging, such as CT, for diagnosis confirmation, further lesion definition, and preoperative evaluation.

Aims and Objectives:
The aim of this study was to enhance comprehension of the occurrence and varieties of congenital lung abnormalities in children, as well as to assess and compare the diagnostic precision of MDCT with that of surgical intervention.

Methodology:
MDCT with contrast CT was performed in children with respiratory complaints and prenatal history of suspicion in targeted imaging for fetal anomalies (TIFFA) or congenital lung malformations (CLMs) using TOSHIBA 8 slice CT; the study population consisted of 40 pediatric patients with a history of chest anomalies during pregnancy in TIFFA or children with abnormal chest X-ray suspicion of lung anomalies for 18 months.

Results:
In a study of 40 pediatric patients who underwent MDCT with contrast to evaluate CLMs, 6 were excluded from further evaluation with contrast due to the absence of pulmonary anomalies on plain CT, leaving a possible diagnosis of s CLM in the remaining 34 cases. Of these, cystic pulmonary airway malformations (CPAM) (41.1%) were the most common, followed by congenital lobar emphysema (17.6%), bronchogenic cyst (14.7%), lung agenesis (11.6%), and phylogenetic lung.

Conclusion:
To notice the characteristics and related anomalies of CLMs and aid in the presurgical evaluation of CLMs, the study concludes that MDCT with contrast is the imaging of choice.
Efficacy of Inhaled Corticosteroids in Patients with Bronchiectasis without Airway Hyperresponsiveness: A Pilot Study
Authors: Ahmed Safia , Sutravey Sesha Sai 
Published: June 2024

Background:
The effect of inhaled corticosteroids (ICS) in stable cases of bronchiectasis without hyperresponsiveness has not been studied. The objective of the study was to assess the effect of inhaled fluticasone 500 µg twice daily on health-related quality of life (HRQoL), pulmonary function, and frequency of exacerbations in stable patients of bronchiectasis without bronchial hyperresponsiveness (BHR) diagnosed by indirect bronchoprovocation test.

Materials and Methods:
It was a pilot study with an open-label randomized control design conducted in a Tertiary Care Chest Hospital, with 40 patients in each arm. Bronchiectasis was diagnosed by high-resolution computed tomography chest. Patients with BHR were excluded by performing an indirect bronchoprovocation test using inhaled adenosine monophosphate. Eighty patients meeting the inclusion criteria were randomized into intervention group (IG) receiving 500 µg fluticasone propionate twice a day and control group (CG) receiving standard care without ICS. Both groups were assessed monthly till 6 months. Clinical data (mainly forced expiratory volume in 1st s [FEV1], number of exacerbations, HRQoL by St. George respiratory questionnaire (SGRQ) was collected at baseline and end of 6 months.

Results:
Eighty (IG - 40, CG - 40) patients of stable state noncystic fibrosis bronchiectasis completed the study. The mean age in our study was IG 49.7 ± 17.6 vs. CG 49.9 ± 16.6, males IG 62.5% vs. CG 60%, most common etiology was tuberculosis IG 40% (16/40) vs CG 37.5% (15/40). Difference in SGRQ score (baseline end of treatment) IG 5.47 vs. CG 1.65 (p = 0.00). Difference in FEV1 IG 0.054L vs. CG 0.004L (P = 0.00), mean number of exacerbations at end of treatment IG – 1 ± 0.9 vs. CG 1.2 ± 1.1.

Conclusion:
Patients with stable bronchiectasis without BHR, treated with inhaled fluticasone 500 µg twice daily for 6 months showed a clinically significant improvement in HRQoL. No statistically significant difference was seen in pulmonary function and frequency of exacerbations.
