Published: February 2023

Background: Kenya has made progress towards the elimination of measles through routine and supplementary immunisation activities; however, sporadic outbreaks still occur. Studies on measles seroprevalence in Kenya are few and extensive analysis of refugee and migrant populations’ immunity against measles is lacking. This cross-sectional study aimed at assessing the presence of immunity against measles in children, adolescents and young adults living in the high urban refugee area of Eastleigh Nairobi, Kenya. Method: A total of 384 samples serum samples were collected from consenting respondents and tested for measles IgG antibodies. Syncytium Inhibition Assay, a neutralisation assay was used to determine functionality. The establishment of herd immunity was calculated using the Plans- Rubio formulae. Results: Seropositive rate for all respondents were 84.38%, while equivocal and negative were 4.95% and 10.68%, respectively. None of the factors analysed was a significant predictor of positive measles antibodies. 87.76% of the total sera were neutralising, while 12.23 % were negative. There was a significant correlation between the neutralisation titres and ELISA values. Conclusion: This study highlights age-specific measles immunity gaps in an urban refugee population. Although measles antibodies are present in all age groups, none has established herd immunity. In order to avert outbreaks in the study population, it is necessary to direct immunisation interventions to increase the measles antibody prevalence to recommended levels.
Quelques repères sur l’évolution de la doctrine mondiale sur l’éducation
Authors: Charlier Jean-Émile 
Published: February 2023

L’examen des programmes lancés par les organisations internationales pour soutenir l’éducation dans le Sud, depuis l’euphorie des années 1960 jusqu’en 2015, fait apparaître, d’une part, que chaque programme tente de corriger les dégâts faits par le précédent, d’autre part, que l’argumentaire qui soutient l’investissement dans l’éducation est fragile et instable. En outre, la doctrine internationale en matière d’éducation n’a pas cessé de procéder à des élargissements à la fois des retours attendus de l’éducation, des catégories de bénéficiaires et de la gamme des opérateurs légitimes d’éducation. Ce faisant, elle a moins tenté de procéder à l’imposition d’un modèle que d’intégrer dans un ensemble plus ou moins cohérent des ensembles hétéroclites de pratiques. Classification JEL : I21, I25
1972-2022 : un demi-siècle de rapprochement entre développement et environnement
Authors: Vivien Franck-Dominique 
Published: February 2023

Alors que le sommet de la Terre, « Stockholm +50 », s’est tenu en juin 2022, cet article fait retour sur la genèse et l’évolution des actions diplomatiques et débats académiques qui ont visé à rapprocher les questions de développement et d’environnement durant ce demi-siècle. Les décennies 1970-1980 peuvent être vues comme une période d’« avant le développement durable » ; les décennies 1990-2000 correspondent à la période d’annonce et d’institutionnalisation de ce dernier ; la décennie 2010 et le début des années 2020 constituent une période d’essoufflement des actions et engagements pris dans ce cadre et semblent annoncer un « après développement durable ».

Les transformations numériques et l’ordre négocié des techniciens des services automobiles au Québec
Authors: Dupuis Mathieu , Murray Gregor , Wu Meiyun 
Published: February 2023

Le discours sur l’impact des changements numériques suit souvent une logique déterministe selon laquelle les transformations induites par ces bouleversements auraient des effets unidirectionnels et déstabiliseraient la nature du travail et des métiers, ainsi que leurs institutions régulatrices. Prendre pour point de départ le fait que cette régulation s’incarne dans un ordre négocié nous amène à analyser ces changements comme étant dépendants des compromis institutionnalisés et du pouvoir des acteurs sociaux qui forment cet ordre. Cet article propose d’analyser ces renégociations à travers une étude de cas sectorielle, l’industrie des services automobiles au Québec et, plus particulièrement, des techniciens qui assurent l’entretien et la réparation des véhicules. Cette industrie est sujette à de multiples pressions provenant des changements technologiques : sur la nature du métier et l’exécution du travail, sur la formation et la production de compétences ainsi que sur les conditions de travail. Notre étude démontre comment ces changements doivent être analysés sous le prisme des tensions au sein de la relation d’emploi, en fonction de l’héritage institutionnel et selon les relations de pouvoir entre les acteurs de ce secteur. Les règles qui émergent de cet ordre (re)négocié étant sujettes à diverses formes d’expérimentations, les contours des compromis institutionnalisés font l’objet d’une transition plutôt que d’une rupture radicale.
Severe pulmonary arterial hypertension in a patient with hereditary hemorrhagic telangiectasia and multiple pulmonary and hepatic arteriovenous malformations
Authors: Aramalla Sunitha , Bhyravavajhala Srinivas , Vanaparty Bharathi , Narayanan Ramakrishna , Yerram Sreekanth 
Published: February 2023

ABSTRACT
Hereditary hemorrhagic telangiectasia (HHT) is a genetic disorder in which there is faulty development of the arteries. There is a high incidence of pulmonary hypertension (PH) in these patients, the pathophysiology of which is not fully known. An increase in cardiac output, causing high-output cardiac failure, and increased pulmonary vascular resistance secondary to genetic mutations are the main reasons. We report a 25-year-old male with HHT who presented with right heart failure secondary to PH in whom both the above mechanisms were operating. The coexistence of giant pulmonary arteriovenous malformations with severe PH is a rare scenario influencing management decisions that are discussed. In addition, this patient highlights the classical visceral vascular malformations in this rare disorder.

Published: February 2023

ABSTRACT
Cardiac involvement in T-cell lymphoma is not uncommon. Pericardial effusion is the most common manifestation of cardiac involvement with restrictive cardiomyopathy (RCM) due to tumor infiltration being extremely rare. The presence of paroxysmal nocturnal dyspnea and orthopnea in a patient presenting with pericardial effusion could be related to tamponade or underlying myocardial disease. Hence, reevaluation after pericardiocentesis is warranted. We describe a 14-year-old boy with advanced T-cell lymphoma presenting with cardiac tamponade. Repeat echocardiography after pericardiocentesis revealed mediastinal mass infiltrating cardiac chambers and great vessels along with features of RCM secondary to tumor infiltration.

ABSTRACT
A patent foramen ovale (PFO) is a frequent incidental finding during echocardiography in otherwise healthy children. In most healthy children with a diagnosis of isolated incidental PFO, no further follow-up or intervention is necessary. In some children, PFO is associated with certain clinical syndromes such as cryptogenic stroke, decompression sickness, migraine, and platypnea–orthodeoxia syndrome. This review discusses PFO anatomy, diagnostic imaging, PFO-associated clinical situations, management options, and the role of PFO in certain congenital heart disease. This review also highlights the current deficiency of pediatric data guiding management of these uncommon but important PFO-associated conditions. Future multicenter randomized controlled studies are necessary to guide the management of these unique and challenging PFO-associated conditions.

Published: February 2023

ABSTRACT
A 3-year-old girl presenting with fever, mucocutaneous inflammation, and acute gastrointestinal symptoms met criteria for the multisystem inflammatory syndrome in children associated with COVID-19 (MIS-C). Echocardiography showed severely decreased left ventricular (LV) function with an apical mass. After treatment with intravenous (IV) immunoglobulin, IV steroids, anakinra, milrinone, and systemic anticoagulation, her LV function rapidly improved and the mass became increasingly mobile. Given the risk of systemic embolization, the mass was excised through left ventriculotomy and pathology confirmed a thrombus.

Published: February 2023

Objective:
This study aimed to estimate and correlate the levels of serum vitamin B12, iron, and their association with family history and cigarette smoking in patients with recurrent aphthous stomatitis (RAS).

Methods:
Sample size was calculated using the earlier prevalence studies with a power of 85% and rounded to 30 considering other confounding factors. Thirty patients with RAS and 30 control subjects were included in this controlled prospective study. A proforma on demographic details and case history was filled followed by serum analysis for Iron and B12. The collected data were analyzed using SPSS 20.

Results:
Family history is a significant predisposing factor for RAS. Vitamin B12 was found to have a significant positive correlation with RAS. Patients with vitamin B12 deficiency, positive family history, and nonsmoking status have been found to have the highest risk for having RAS. Binary logistic regression analysis revealed a significant relationship between vitamin B12 and RAS (probability P =0.001).

Conclusion:
Our study had shown a positive correlation of RAS with family history and vitamin B12 deficiency.

Authors: Anbumeena S. , Kannan A. , Krithika C.L. , Vasanthi V. 
Published: February 2023

Introduction:
Radiography is an inseparable tool in dentistry. Radiation can induce DNA damage as well as cellular damage.

Aims and Objectives:
To estimate the genotoxicity and cytotoxicity after taking Orthopantomograph (OPG). To compare the result between five different age groups.

Materials and Methods:
Buccal mucosal smears were collected from the participants and stained using the PAP method and PAS method. It was evaluated for genotoxicity and cytotoxicity.

Settings and Design:
The study group consisted of 60 participants. They are divided into five different groups with 12 in every single group.

Statistical Analysis Used:
Wilcoxon Signed Ranks Test was used within groups. Kruskal–Wallis test was used for continuous data.

Results:
The mean of cytotoxicity after taking OPG was significantly increased (P < 0.05). Though there was an increase in micronuclei expression, no statistically significant difference was evidenced (P > 0.05).

Conclusion:
The result of our study reveals that OPG did not cause any chromosomal damage, but it is capable of inducing cytotoxicity in buccal mucosal cells in all age groups.
Foramen Magnum as Determinant of Sexual Dimorphism in Sri Ganganagar Population
Authors: Verma Pradhuman , Gupta Nidhi , Sameera Y. , Faraz Samar Ali , Sharma Prabal , Sharma Bhumika 
Published: February 2023

Background:
In explosions, mass disasters, and warfare, human remains are got in fragmented states. Only strong bones that resist fracture can be used for personal identification in forensics. The foramen magnum (FM) dimension at the base of the skull is one such region that can be used for sex discrimination using radiographs.

Aim and Objectives:
To test evaluate sexual dimorphism in FM morphometric measurements and shape using digital submentovertex (SMV) radiograph among the Sri Ganganagar population.

Materials and Methods:
100 digital SMV radiographs (50 males and 50 females) were randomly selected from the daily radiographic record of the patients with an age range of 25 to 65 years who visited the OPD and require SMV radiographs for diagnosis. The selected SMV radiographs were assessed for FM dimensions (longitudinal and transverse diameters, circumference, area, and FM index). Also, one particular shape was assigned to FM based on the radiographic image according to Chethan et al. classification. All the measurements were performed by two maxillofacial radiologists independently, and the data thus obtained were subjected to discriminant analysis for the evaluation of sexual dimorphism.

Results:
Values of four parameters out of five (transverse diameter, circumference, area, and foramen index) were found statistically significantly higher in males. The most common morphology of FM was an egg shape (50%), whereas round (3%) was the least common morphology. Circumference FM was the best indicator of gender determination followed by area, transverse diameter. and foramen index. The SMV radiographs for FM showed an overall accuracy of 69.73% in sex determination.

Conclusion:
The study showed that SMV radiographic FM morphometric measurements can be used for sex determination among the Sri Ganganagar population.
Assessment and Comparison of Condylar Position Based on Joint Space Dimensions and Gelb 4/7 Grid using CBCT
Authors: Vankadara Sairam , Akula Baandhavi , Nissi Kolluri 
Published: February 2023

Background:
Temporomandibular joint (TMJ) is a unique joint. An optimal position of the mandibular condyle in the glenoid fossa is a fundamental question in dentistry, and there is no quantitative standard. Thus, the most common condylar position in the glenoid fossa can be determined by the dimension of the joint space and Gelb 4/7 grid using cone-beam computed tomography (CBCT).

Aim:
To analyze the position of the condyle and joint spaces in the normal temporomandibular joint and to compare the efficacy of the Gelb 4/7 grid over dimensions of joint spaces to assess optimum condylar position using CBCT.

Materials and Methods:
CBCT images of 40 patients (right and left) without a history of TMJ disorders were selected. Anterior (Ajs), superior (Sjs), and posterior joint spaces (Pjs) on sagittal slices, medial (Mjs), and lateral (Ljs) on coronal view were measured and Gelb 4/7 grid on sagittal slices used to assess the condylar position.

Results:
Significant difference between right and left sides in Ajs, Sjs, Mjs, and Ljs values. Significant differences were noticed in Mjs, Ajs values between males and females. Centric position is the most common position of the condyle, and 4/7 position is the most common according to Gelb 4/7 grid.

Conclusion:
Gelb 4/7 position was found to be the most common anatomical position of the condyle in healthy TMJs, and centric relation position was the most common based on joint space dimensions.

India contributed 2,391 (4.32%) publications on telemedicine to a total of 55,304 publications worldwide until 2021. There were 886 (37.05%) papers that appeared in open access mode. The analysis revealed that the first paper was published in the year 1995 from India. Steep growth in the number of publications was observed in 2020 with 458 publications. The highest, 54 research publications, appeared in the “Journal of Medical Systems.” The All India Institute of Medical Sciences (AIIMS), New Delhi, contributed the highest number of publications (n = 134). A considerable overseas collaboration was observed (USA: 11%; UK: 5.85%).

Conclusions:
This is the first such attempt to address the intellectual output of India in the emerging medical discipline of telemedicine and has yielded useful information such as leading authors, institutions, their impact, and year-wise topic trends.
Schiele, Egon (1890–1918)
Authors: Jordan Sharon 
Published: February 2023

Egon Schiele is one of the most original artists of the early 20th century and a major figure associated with the stylistic movement, Expressionism. He has a unique linear technique that conveys a heightened energy or dynamic intensity, to which chromatic dissonance is frequently added with the application of watercolour.
The majority of Schiele’s artworks explore extreme facets of the human experience expressed through the human body, with external physical appearances serving as expressions of an existential reality or an internal state of being. With his interest in psychological and sexual subject matter, he is aligned with Oskar Kokoscha, the other foremost representative of Austrian Expressionism.
Circumstances of the Opening of the Polytechnic Institute in Guides to Kyiv (1900 – Early 20th Century)
Authors: Shevchuk T. 
Published: February 2023

In the 19th and at the beginning of the 20th century. in Kyiv, a city that attracted many visitors, nationwide trends in the development of the coal, metallurgical, machine-building, light, food industry, and agriculture industries were marked, and at the same time, there was a lack of engineers, agronomists, and technicians. Against this background, there was an urgent need to establish a higher institution of technical education in Kyiv, which became the Kyiv Polytechnic Institute, opened in 1898. At the same time, it was during this period that tourism, which before was rather a supplement to pilgrimage, gradually grew into a mass one, and accordingly, guides, as a publication outlining noteworthy routes, became more and more popular. Therefore, it is important to trace how the new university entered the sphere of attention of visitors to the city, and what role the authors of guidebooks – valuable comprehensive sources on the history of everyday life in the city – played in this. The article examines the peculiarities of coverage in Kyiv guidebooks of the circumstances of the opening of the Kyiv Polytechnic Institute. It can be concluded that the most information about the circumstances of the opening of the Kyiv Polytechnic Institute is contained in those guides (except K. Svirskiy) that were published immediately after the opening of this educational institution (in 1900 and 1901), although one of them – a reprint of M. Sementovskyi – in the first in the first turn it was aimed at pilgrims, and only in the second – at social guests of the city. Probably, the compilers sought to record as accurately as possible the still unfinished process unfolding before them.V. Chekhovsky, who openly positioned his work as dedicated to the modern features of the Kyiv of that time, disclosed in it the main, in his opinion, prerequisites and key aspects of the establishment of the institute from planning to the implementation of a concrete project, and among the most prominent persons involved, he did not overlook those ethnically related to Poles, but did not exaggerate their role. Later editions do not go beyond the placement of information, according to the authors, most important for average travellers. Even in the most succinct coverage of events, the importance of the role of donations from private individuals is noticeable, sometimes with an indication of the cost of the project.
The Influence of Collateral Availability on Access to Credit by Small and Medium Enterprises (SMEs) in Meru County
Authors: Onkundi Gladys , Munene Halldess Nguta , Walubuka Elijah 
Published: February 2023

Purpose: Small and Medium Enterprises (SMEs) significantly contribute to both social and economic development of people largely through their roles in job and innovation creation, and revenue generation. Majority of SMEs are undercapitalized due to inaccessibility of credit facilities. This adversely influence their capacity to invest in productive ventures and realize their corporate goals. Factors that influence SMEs’ access to credit are not well known. Thus, the current study sought to establish the influence of collateral availability on access to credit by SMEs in Meru County.
Methodology: The study was guided by the theory of information asymmetry and the pecking order theory. The study was based on the descriptive survey design. The study targeted 204,810 SMEs in Meru County of which 384 SME owners were sampled using stratified sampling. Quantitative data was analyzed using both inferential and descriptive statistics.Qualitative data was analysed thematically.
Findings: The study found that majority of SMEs in Meru County are able to access credit from SACCOs but not from MFIs and Banks without necessarily having to provide collateral since guarantors’ savings act as security for the loans.
Recommendations: The study recommend that SMEs should ensure that they do not have negative listing by CRB to increase their chances of accessing credit. The study also recommend SMEs owners to acquire training on how to prepare and maintain proper financial statements.
