Susciter la mise en débat démocratique et citoyenne des données chiffrées sur l’Économie sociale et solidaire
Authors: Bidet Éric , Richez-Battesti Nadine
Published: November 2021

Au cours des deux dernières décennies, la mesure du poids de l’économie sociale et solidaire (ESS) a suscité un intérêt croissant de la part de divers acteurs aux niveaux national et international, sur la base de méthodologies et de cadres de référence diversifiés qui ne sont pas toujours clairement identifiés ni questionnés par ceux qui les utilisent, alors même qu’ils véhiculent parfois des normes implicites. Les auteurs analysent les questions soulevées par la mesure de l’ESS au niveau national français, puis examinent la complexité qui caractérise cette question au niveau international où s’agrègent des référentiels et normes encore plus variés. Cet article explique pourquoi les données doivent être coproduites et sous-tendues par une réflexion sur leur usage afin d’être réellement utiles aux différents acteurs et organismes qui s’y réfèrent, ainsi qu’aux citoyens.
Vers des comptes-satellites nationaux « tiers-secteur et économie sociale » construits selon le handbook 2018 de l’ONU ?
Authors: Archambault Édith , Ramos Ana Cristina
Published: November 2021

Après avoir rappelé l’intérêt d’un compte-satellite ancré dans la comptabilité nationale pour comparer dans le temps et l’espace les organisations de l’économie sociale, cet article retrace l’historique du handbook 2018 de l’ONU qui propose une méthodologie d’élaboration du compte satellite prenant en compte les critiques adressées au manuel de 2003 (qui ne concernait que les institutions sans but lucratif). Les auteures analysent les principaux concepts du handbook « tiers-secteur et économie sociale » de 2018 du point de vue de la France où un compte-satellite de l’ESS est en cours de construction à l’Insee, et soulignent la proximité entre le périmètre de l’ESS selon la loi de 2014 et selon ce handbook 2018. Enfin, elles présentent le compte-satellite modulaire du Portugal comme un exemple de bonne pratique, avant d’esquisser en conclusion les usages qui pourront être faits à l’avenir de la mise en place généralisée d’un tel outil.

This study incorporates the design, fabrication, implementation and evaluation of soil-based Vertical Floating Bed (VFB). The VFB has contained six plots in three vertical layers, each layer having vertical distance of 0.61 m. The structural load was calculated and three water barrels were used to maintain stable floating condition. Red Amaranth was grown and the production was evaluated with horizontal farm based on no. of leaves (NoL), stem size (SS), crop weight, crop height (CH), root zone depth and total yield (Y). Statistical analysis showed that there was a significant difference in yield among different layers of VFB with horizontal layer. Most of the considerable yield (NoL 10 nos, CH 0.27 m, SS 12 mm, Y 1.54 kg) was achieved from the top layer of the structure (L1). The lowest production (NoL 7 nos, CH 0.19 m, SS 9 mm, Y 0.83 kg) was found in the bottom layer (L3). The elevation of different layers caused growth variances due to sunlight exposure differences. The study suggested that healthy production will be capable as insect and weed infestation was negligible. It can also be a sustainable method to grow vegetables in low-land areas.
Object-Based Trace Model for Automatic Indicator Computation in the Human Learning Environments
Authors: Batchakui Bernabé , Djotio Thomas , Moukouop Ibrahim , Ndouna Alex
Published: November 2021

This paper proposes a traces model in the form of an object or class model (in the UML sense) which allows the automatic calculation of indicators of various kinds and independently of the computer environment for human learning (CEHL). The model is based on the establishment of a trace-based system that encompasses all the logic of traces collecting and indicators calculation. It is im-plemented in the form of a trace database. It is an important contribution in the field of the exploitation of the traces of apprenticeship in a CEHL because it pro-vides a general formalism for modeling the traces and allowing the calculation of several indicators at the same time. Also, with the inclusion of calculated indica-tors as potential learning traces, our model provides a formalism for classifying the various indicators in the form of inheritance relationships, which promotes the reuse of indicators already calculated. Economically, the model can allow organi-zations with different learning platforms to invest only in one traces Management System. At the social level, it can allow a better sharing of trace databases be-tween the various research institutions in the field of CEHL.

Published: November 2021

The irruption of digital technologies in social contexts and their integration in educa-tion has led to new learning environments where the communication, interaction and access to knowledge are an essential part of the educational process. This paper shows a literature review and mapping of the most important technological tools used in the contexts where heritage teaching has been conducted in the last decade. For this aim developed a bibliometric analysis of scientific publications in high impact journals through selective searches in the specialized databases Scopus and Science Direct. The findings show trends in the educational practice approach regarding herit-age, integrating emerging technologies such as augmented reality, 3D modelling, arti-ficial intelligence, QR coding and virtual reality that offer situated and immersive learning experiences on mobile apps and web-based platforms. From the studies analyzed in different contexts, it is concluded that the integration of digital technolo-gies in the teaching and heritage appropriation is a field that in recent years shows a clear increase, so that it is necessary to consider the potential of these tools in it’s diffusion, teaching and preservation to strengthen existing work lines and open up possibilities to future studies.

The pandemic has accelerated the use and development of video conferenc-ing platforms due to COVID-19, and it is necessary to find an application that best suits our requirements. This article evaluates nine features of nine video conferencing applications to find the best choice. A detailed analysis has been conducted in this article using surveys to collect data from two samples at national and international level. The methodology followed is the CDIO methodology, a tool to address complex problems in four stages: conception, design, implementation, and operation. The primary aim of this paper is to examine which is the best livestreaming option according to the selected criteria, using, as references, well-known applications such as Jitsi, Zoom, Microsoft Teams, Google Meet, Big Blue Button, among others. An application of multicriteria analysis is also shown to support the evalua-tion of these platforms compared to the established criteria.
Predicting Attack Surface Effects on Attack Vectors in an Open Congested Network Transmission Session by Machine Learning
Authors: Aljojo Nahla
Published: November 2021

This paper examined the impact of a network attack on a congested transmission session. The research is motivated by the fact that the previous research community has neglected to evaluate security issues related to network congestion environments, and has instead concentrated on resolving congestion issues only. At any point in time, attackers can take advantage of the congestion problem, exploit the attack surface, and inject attack vectors. In order to circumvent this issue, a machine learning algorithm is trained to correlate attack vectors from the attack surface in a network congestion signals environment with the value of decisions over time in order to maximise expected attack vectors from the attack surface. Experimental scenario that dwell on transmission rate overwhelming transmission session, resulting in a standing queue was used. The experiment produced a dataset in which a TCP transmission through bursting transmission were capture. The data was acquired using a variety of experimental scenarios. Nave Bayes, and K-Nearest Neighbours prediction analyses demonstrate strong prediction performance. As a result, this study re-establishes the association between attack surface and vectors with network attack prediction.
A Multi-Sided Platform to Activate the Sharing of Digital Labs
Authors: Kammerlohr Valentin , Uckelmann Dieter , Baalsrud Hauge Jannicke
Published: November 2021

This paper presents a business model for digital laboratories (labs) to promote sharing in network organizations. Using information systems design science research methodology, a multi-sided platform is created and evaluated as a sustainable business model. Digital labs complement theoretical concepts in science, technology, engineering, and mathematics (STEM) to promote understanding of concepts, practical knowledge, and experiences. However, these labs are expensive and typically only available to local user groups, and not every university can offer the same or equivalent labs. Many universities are not well prepared to share labs with other institutions or to be part of a network organization. Among the findings are that digital labs are becoming more important, that there is an emerging trend from product- to service-oriented solutions, that a lab-sharing marketplace should provide targeted offerings for teaching and training, and that industry customers and students are showing interest in digital labs education content. The willingness to pay for students and industry is there, but for students the discussion remains ethical in nature as to who should pay for education. On the other hand, industry customers point out that there is a fear of losing intellectual property and security risks. This paper shows how a sustainable business model for digital labs activates lab sharing. Then universities can offer a better curriculum, instructors have more opportunities to provide a good education, and only then can students have access to more lab environments.

Les enjeux de l’implantation de l’approche neurolinguistique, une nouvelle méthode d’apprentissage du français langue seconde auprès d’élèves allophones en contexte scolaire
Authors: Guedat-Bittighoffer Delphine , Dat Marie-Ange , Humeau Camille , Nocus Isabelle
Published: November 2021

En France, les élèves allophones vivent une situation difficile au sein du système scolaire français en ce qui concerne l’acquisition du français langue seconde (FLS). Comment faire acquérir le FLS à ces jeunes apprenants migrants, parfois non scolarisés antérieurement dans leur pays d’origine, à l’oral et à l’écrit dans des modalités temporelles très courtes ? L’approche neurolinguistique (ANL) est une méthode d’apprentissage du français langue étrangère ou seconde, créée et conçue par Germain et Netten en 1997. Il nous a semblé pertinent d’évaluer si l’ANL pouvait permettre, notamment pour les débutants, de faciliter l’acquisition de compétences langagières et de les sécuriser sur le plan affectivo-émotionnel. Le principal objectif de cet article est de présenter les résultats qualitatifs issus de la première année d’expérimentation que nous menons depuis 2019 dans trois dispositifs d’accueil utilisant l’ANL auprès de ces jeunes allophones.
Philippe Raynaud, la philosophie politique de l’école et la formation des enseignants. Un regard à l’aune de l’individualisme démocratique
Authors: Roelens Camille
Published: November 2021

L’objet de cet article est de proposer un regard sur les contributions au débat public du philosophe Philippe Raynaud s’agissant de la confrontation de l’institution scolaire à l’individualisme démocratique. Penser le modèle éducatif français et ses transformations récentes est le premier souci de Raynaud, et c’est par ce prisme qu’il dessine une philosophie politique de l’école dont nous donnons ici à voir les traits caractéristiques (1.1). La question de la formation des enseignants constituant un point de cristallisation de ses préoccupations et avis sur la politique scolaire, nous y consacrerons ensuite un temps d’étude spécifique (1.2). Le dispositif analytique et argumentatif de Raynaud paraissant bâti comme une réponse potentielle à certaines inquiétudes face aux effets d’un individualisme démocratique néo-tocquevillien dans l’éducation, c’est dans une élucidation de ce que peut revêtir ce mot d’ordre apparemment impossible de former aujourd’hui l’individu, par l’individu et pour l’individu que ce trouble nous parait pouvoir être partiellement dissipé (2).

Napoléon Arlequin ou la métaphore théâtrale
Authors: Astbury Katherine
Published: November 2021

En 1814 on établit un lien étroit entre Napoléon et les formes de théâtre populaire, renforçant ainsi son manque d’authenticité. Des commentateurs comme Nodier rejetèrent le théâtre populaire comme n’étant fait que pour les oreilles et les yeux. C’est un spectacle qui n’offre que des « émotions tièdes et communes », autrement dit simulées et illusoires. En mettant l’accent sur l’illusion et la fausseté du théâtre forain, et en rapprochant Napoléon et ses proches (Cambacerès par exemple) de la commedia dell'arte en particulier, les pamphlétaires et les dessinateurs renforcent l’infériorité et le ridicule du régime impérial. Or, sous les Cent-Jours les bonapartistes ripostent et réclament rapidement les références théâtrales à leur tour. Cet article tracera l’évolution et les métamorphoses de cette métaphore afin de mieux saisir les polyvalences et la plasticité au cœur de cette imagerie.
Masques et miroirs de l’Empereur autour du sacre : Lemercier et Chénier

Published: November 2021

Quand peut-on parler en effet légitimement d’un « masque de Napoléon » ? Quand c’était l’intention de l’auteur, quand la critique contemporaine ou quand des témoignages suggèrent cette lecture. Nous essaierons aujourd’hui d’approcher le théâtre sérieux à travers deux auteurs exemplaires à bien des égards pour notre réflexion, Lemercier et Chénier, tous deux auteurs de tragédies « politiques », tous deux victimes de la censure, tous deux présentant à l’empereur des masques assez transparents pour servir de miroirs.
Les « Journée[s] de Saint-Cloud » : les pièces de circonstance autour du coup d’état du 18 Brumaire
Authors: Perazzolo Paola
Published: November 2021

Au lendemain du coup d’état du 18 Brumaire, le monde dramatique s’empresse de célébrer Bonaparte par des couplets et des impromptus composés pour la circonstance ainsi que par la mise au répertoire d’ouvrages qui exaltent le général, noircissent les Jacobins – dont l’épuration est historiquement en cours –, stigmatisent l’instabilité et l’inefficacité du gouvernement du Directoire. Les pièces traitant la « Journée de Saint-Cloud » sont si nombreuses que la censure étatique est forcée d’intervenir pour en interdire la représentation ou pour imposer la réécriture de textes souvent trop politisés, la gaité vaudevillesque qui en caractérise la plus grande partie s’accompagnant d’une « écriture slogan » permettant la porosité entre espace de la fiction et espace public spécifique aux ouvrages de circonstance. D’après Muret, « le théâtre, qui avait tant célébré la République, l’enterrait gaiement en couplets ». Le monde dramatique concourt en effet de façon massive, ainsi que la presse et d’autres productions contemporaines, à légitimer le coup d’état et à couvrir le général du masque du « héros-sauveur » invaincu et pacificateur d’une République en danger, aidant de la sorte Bonaparte à devenir Napoléon.
La culture matérielle napoléonienne dans les expositions de l’après-Waterloo à Londres, 1815-1819
Authors: Cochrane Nicole
Published: November 2021

Cet article examine les expositions d'art et de culture matérielle napoléonienne présentées à Londres dans les années qui ont suivi la bataille de Waterloo. En se concentrant sur trois principaux musées et espaces d'exposition, le Waterloo Museum de George Palmer, l’Egyptian Hall de William Bullock et les Waterloo Rooms de Pall Mall, il explore comment l’exposition d’art, de meubles, de vêtements et d’armes napoléoniens au public britannique met en lumière une tension dans la conscience publique de Napoléon, des guerres napoléoniennes et de la vie culturelle britannique. Elle démontre que les musées étaient un espace important pour l'interaction napoléonienne, un lieu où les expositions pouvaient simultanément renforcer les récits de la défaite et de la suprématie britannique tout en permettant une intimité tactile avec les objets de la vie personnelle et familiale de l’ancien Empereur.
Et puis soudain, au détour du sentier, une œuvre d’art...
Authors: Poli Marie-Sylvie
Published: November 2021

On envisage une randonnée sur un itinéraire montagneux ponctué d’œuvres de land art comme une expérience culturelle ayant des points en commun avec une expérience de visite de musée. On aborde d’abord les dimensions patrimoniales de ce dispositif nommé « L’art en marche » dans la Réserve Géologique des Hautes-Alpes. On découvre ensuite les motivations qui ont poussé la randonneuse à entreprendre la visite de ces sites escarpés dans lesquels des artistes contemporains ont créé, en pleine nature, des œuvres uniques en lien étroit avec les paysages et les hommes de Haute-Provence. On discute enfin les effets et les retentissements mémoriels d’une randonnée qui mène du musée Gassendi de Digne-les-Bains au Refuge d’Art des bains thermaux, une des œuvres de l’artiste Andy Goldsworthy.
Condoléances numériques : la mort de l’ancien président de la République Jacques Chirac dans le compte Twitter du journal Le Monde
Authors: Modena Silvia
Published: November 2021

La mort de l’ancien Président de la République française, Jacques Chirac, est survenue le 26 septembre 2019. Le journal Le Monde, dans le cadre de son offre multiplateforme, a publié à travers son compte Twitter le nécrologe numérique suivant : « Jacques Chirac est mort ». Nous avons analysé les 246 réactions que les internautes du journal ont manifestées le jour même de la mort de l’ancien Président. Ces 246 tweets ont une nature discursive très hétérogène qui rappelle la pluralité d’engagements des messages écrits dans les registres des condoléances en version papier. Or, les réactions prises ici en examen sont majoritairement élogieuses mais certaines réactions, grâce à leur nature numérique, mobilisent des renvois interdiscursifs et des interactions conversationnelles critiques envers l’image de l’ancien président Chirac.
An Electromechanical In Situ Viscosity Measurement Technique for Shear Thickening Fluids
Authors: Haydarlar Gökhan , Sofuoğlu Mehmet Alper , Gürgen Selim , Kushan Melih Cemal , Tekkalmaz Mesut
Published: November 2021

This paper presents the feasibility of developing an electromechanical in-situ viscosity measurement technique by analyzing the detectability of small variations in the viscosity of different shear thickening fluids and their different compositions. Shear thickening fluid (STF) is a kind of non-Newtonian fluid showing an increasing viscosity profile under loading. STF is utilized in several applications to take advantage of its tunable rheology. However, process control in different STF applications requires rheological measurements, which cause a costly investment and long-lasting labor. Therefore, one of the most commonly used in-situ structural health monitoring techniques, electromechanical impedance (EMI), was used in this study. In order to actuate the medium electromechanically, a piezoelectric wafer active sensor (PWAS) was used. The variations in the spectral response of PWAS resonator that can be submerged into shear thickening fluid are analyzed by the root mean square deviation, mean absolute percentage deviation and correlation coefficient deviation. According to the results, EMI metrics provide good correlations with the rheological parameters of STF and thereby enabling quick and low-cost rheological control for STF applications such as vibration dampers or stiffness control systems.

Published: November 2021

Hyperthermic intraperitoneal chemotherapy (HIPEC) is a technique, which delivers heated chemotherapeutic agents into the peritoneal cavity. It has been shown to improve prognosis and survival rate in patients of colorectal, ovarian and gastric cancers with peritoneal metastasis. A 57-year-old man diagnosed with primary colorectal carcinoma and pseudomyxoma peritonei was posted for HIPEC surgery. General anaesthesia with epidural analgesia (pain management) and invasive lines (arterial, central) for managing fluid shifts were used. Stroke volume variation was measured throughout the 19-hour procedure for goal directed fluid therapy (GDT) and to maintain urine output. Temperature monitoring with deliberate cooling measures were used during the period of HIPEC along with serial arterial blood gas analysis (ABG).
A Good Outcome Following Delayed Debridement of Lumbar Paraspinal Abscess after Postoperative Epidural Catheterization: Case Report
Authors: Salim Azizul Akram , Abang Abdillah Dayang Shariza , Lim Hong Chun , Johari Joehaimey , Yusof Mohd Imran
Published: November 2021

Paraspinal abscess or clinically significant soft tissue infection following epidural analgesia is a rare but serious complication if left untreated. We report a 54-year-old gentleman with underlying chronic diabetes mellitus who had a motor vehicle accident and had undergone several surgeries. A course of steroid was provided for delayed left lower motor neuron facial nerve palsy (House-Brackmann stage 4). The epidural catheter was inserted with a single attempt at the L3/L4 level. One month later, he complained of crippling lower back pain and growing swelling with a punctum. MRI showed a paraspinal abscess with bilateral involvement of the spinae erector. This report is intended to highlight the excellent outcome of surgical treatment for paraspinal abscess despite the late presentation. A high level of suspicion should be taken into account when the patient is immunocompromised, particularly with steroid use and chronic diabetes mellitus. Early detection via MRI, high suspicion index and immediate surgery have extraordinary benefits in managing paraspinal abscesses.
Case Report: Can Steroids Help in a Case of Allodynia Following Spinal Anaesthesia for a Caesarean Section?
Authors: Mahrous Reham , Abd El Fattah Doaa Alaa El dien , Hasanin Ahmed , Ibrahim Mohamed Ahmed , Abdelhakeem Amr K.
Published: November 2021

Most of the anaesthesia related neurological complications are associated with paresthesia upon introduction of the spinal needle. Steroids may shorten the duration of the effects caused by nerve injury. A 27-year-old female patient undergoing caesarean section experienced paresthesia during the intrathecal introduction of the spinal needle. After the spinal anaesthesia wore off, she developed tactile allodynia. Intravenous hydrocortisone was given; marked improvement of pain and allodynia was observed. Contact of the needle with a nerve root may have caused an inflammatory response. The benefit of steroids in cases of nerve injury is still debatable. They likely decrease the levels of autoantibodies that delay nerve regeneration.

Published: November 2021

Background

In response to the growing coronavirus disease 2019 (COVID-19) pandemic and the shortage of laboratory based molecular testing capacity and reagents, multiple diagnostic test manufacturers have developed rapid and easy to use devices to facilitate testing outside laboratory settings. These kits are either based on detection of proteins from SARS-CoV-2 virus or detection of antigen or human antibodies generated in response to the infection. However, it is important to understand their performance characteristics and they must be validated in the local population setting.

Design and methods

The objective is to assess the validity of the rapid test for IgG and IgM immunoglobulins compared to the current gold standard reverse transcription polymerase chain reaction (RT-PCR) test. A total of 16951 asymptomatic individuals were tested by the Ministry of Public Health track-and-trace team using both rapid immunodiagnostic test and RT-PCR as part of screening across various random settings with potential risk of community interaction prior to gradual lifting of restrictions in Qatar. Rapid test was considered to be posiive if both IgG and IgM are positive, while only IgG/IgM positive was considered as rapid test negative. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated.

Results

The sensitivity of rapid test kit was found to be 0.9%, whereas the specificity was found to be 97.8%. the PPV was found to be 0.3% whereas the NPV was found to be 99.4%.

Conclusions

Based on the outcome and results of the study, it appears that the sensitivity and PPV of the rapid antibody test are low. As such, this test is not recommended for use to assist in taking clinic-based decisions or decisions related to quarantine/isolation.
The Association of Alcohol Use Disorder and Chronic Plaque Psoriasis
Authors: Mahajan Vikram K. , Dhattarwal Niharika , Chauhan Pushpinder S. , Mehta Karaninder S. , Sharma Reena , Sharma Anuj , Singh Vijay K. , Sharma Jyotshna , Hooda Sheenam
Published: November 2021

Background:

Association between alcohol consumption, alcohol use disorder, and clinical features of psoriasis patients has not been adequately studied in the Indian context.

Objectives:

To study the frequency of alcohol consumption, alcohol use disorder, and its association with age, gender, duration, and severity of psoriasis.

Materials and Methods:

One hundred and forty-six (M: F 6.3:1) patients completed the Alcohol Use Disorder Identification Test (AUDIT) questionnaire by World Health Organization (WHO). Excessive drinkers, occasional drinkers, and abstainers were defined. AUDIT provided a measure of alcohol consumption, its dependence, and its impact on daily life. The severity of psoriasis was graded as mild, moderate, and severe.

Results:

Seventy-four (50.7%) patients were aged ≤40 years and 51.4% of patients had the disease for <5 years. Psoriasis was mild in 48.6% and moderate to severe in 51.4% of patients, respectively. Only males (32.9%) were consuming alcohol in varying amounts; 19.9% were occasional drinkers (AUDIT score <8). Other 67.1% of patients completely abstained from alcohol consumption (AUDIT score 0). The remaining 13% were regular drinkers (AUDIT score >8) and had more severe psoriasis compared to patients having AUDIT score <8 (P < 0.05). A high level of alcohol use disorder and alcohol dependence was present in one patient each.

Limitations:

Few patients, particularly females may not have disclosed their alcohol consumption due to fear of stigmatization. Small number of patients, hospital-based cross-sectional study design, and no follow-up for clinical improvement after cessation of alcohol are other limitations.

Conclusions:

Alcohol consumption was associated with alcohol use disorder in 32.9% of patients (AUDIT score >8) and significantly severe psoriasis compared to 67.1% abstainers. Whether increased alcohol consumption is a consequence or a risk factor for chronicity of psoriasis needs large linear studies for confirmation.

All specimens of skin tumors were analyzed grossly and microscopically. Immunohistochemistry was done wherever possible.

Results:

A total of 232 skin tumors were seen; of which 123 cases were benign (53.0%) and 109 cases were malignant (47.0%). The mean age of patients with benign and malignant skin tumors was 40.3 ± 19.9 and 60.8 ± 14.8 years, respectively. The most common site was face (n = 106; 45.7%) followed by limbs (n = 44; 19.0%). The male:female ratio of benign and malignant tumors was 1.01:1 and 1.31:1, respectively. Among the benign tumors, keratinocytic tumors were the commonest (n = 57; 46.3%) followed by the melanocytic tumors (n = 37; 30.1%) and appendageal tumors (n = 29; 23.6%). The most common malignant skin tumors were the keratinocytic tumors (n = 87; 79.8%) followed by 12 cases (11%) of hematolymphoid tumors and five cases (4.6%) each of melanocytic and appendageal tumors.

Limitations:

The lack of clinical and dermatoscopic correlation and inclusion of retrospective data are the limitations of this study.

Conclusions:

Skin tumors affect people of all ages. The benign tumors are seen in the younger age group as compared to malignant tumors. Face is the most common site and keratinocytic tumors are the most common skin tumors in both benign and malignant categories.

Published: November 2021

Background:

Psoriasis is a chronic inflammatory dermatosis associated with psychological morbidity. Like mental illness, it is also associated with stigma. Very few studies from India have evaluated stigma experienced by patients with psoriasis.

Aim of the Study:

To study stigma in patients with psoriasis (in the form of internalized stigma, perceived stigma, and social-participation-restriction stigma) and its relationship with demographic and clinical variables.

Methodology:

104 patients with psoriasis assessed on the internalized stigma of mental illness scale (ISMIS), explanatory model interview catalogue stigma scale, participation scale (P-scale), perceived social support, total score of Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder (GAD-7) scale, Dermatology Life Quality Index, and Psoriasis disability index.

Results:

On ISMIS, overall, 27.9% had experienced stigma. On domains, majority of the participants experienced discrimination (52.9%) followed by stigma resistance (51.9%), stereotype (26.0%), social withdrawal (24.1%), and alienation (23.1%). Majority of them reported mild restriction. As per the evaluation by a qualified psychiatrist, about 30% of the participants had at least one psychiatric diagnosis. On comparison, those with the presence of co-morbid psychiatric illness experienced a higher level of stigma on each domain of ISMIS except discrimination and stigma resistance. Lower social support was associated with higher stigma in all the domains. All the domains of ISMIS except discrimination and stigma resistance were associated with a higher level of anxiety and depression, poor quality of life, and higher disability.

Conclusion:

The patients with psoriasis experience a significant amount of stigma and stigma is associated with the presence of psychiatric morbidity, lower social support, higher restriction, and more disability.

Nevus sebaceous of Jadassohn is a cutaneous hamartoma that is associated with various benign and malignant cutaneous tumors. Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign adnexal tumors. Simultaneous occurrence of all three tumors at the same site is extremely rare, which has raised several questions regarding their origin and pose a diagnostic challenge owing to considerable overlap in clinical and histological features. However, limited case reports have hindered our understanding of these tumors and their natural behavior. Herein, we report a case of a hairless scalp plaque in a 43-year-old male which on histological examination showed presence of syringocystadenoma papilliferum and tubular apocrine adenoma in the background of nevus sebaceous. We also made an attempt to review the available literature and understand the origin and look for clues to aid in accurate diagnosis of such tumors.

Authors: Saha Indraneel , Podder Indrashis , Chowdhury S.N. , Bhattacharya Susmita
Published: November 2021

Background:

Dermatophytosis has recently emerged as a major public health problem in the Indian subcontinent, most cases becoming chronic and recurrent.

Aims:

Assessing the clinico-epidemiologic and mycologic profile of treatment naïve, chronic, recurrent and steroid-modified dermatophytosis.

Materials and Methods:

We conducted across-sectional study involving 111 cases of dermatophytosis. Detailed epidemiology, clinical parameters, treatment history and other host factors were assessed along with scraping for potassium hydroxide (KOH) and fungal culture.

Results:

Among 111 patients,(F: M 1.7:1; mean age 44.4 ± 18.2 years), 51.4% were treatment naïve, while 34.2% and 14.4% presented with chronic and recurrent tinea respectively. Family history and sharing of fomites among infected family members was commoner in the latter groups (P = 0.001). Topical steroid application was reported in 49.5%, however only 7.2% presented with steroid modified tinea. Tinea corporis et cruris (41.4%) was the predominant clinical type followed by tinea corporis (34.2%) and tinea cruris (27.9%). KOH mount and culture were positive in 62.2% and 39.6% cases respectively; commonest isolates being Trichophyton rubrum, and Trichophyton mentagrophytes complex in 15.3% cases each. Trichophyton rubrum was the commonest etiology for treatment naïve and recurrent cases, while Trichophyton mentagrophytes was the commonest isolate from chronic and steroid-modified cases (P = 0.0003). Interestingly, T.mentagrophytes complex and T. rubrum were the commonest causes of tinea corporis and tinea cruris respectively (P = 0.07).

Conclusion:

Trichophyton rubrum was the commonest organism in treatment naïve and recurrent cases, while Trichophyton mentagrophytes complex accounted for most cases of chronic and steroid modified tinea. The difference in predominant species seems to be a major contributory factor for chronicity and recurrence. However, several host factors like topical steroid use and sharing of fomites also play additional roles.

The microalgae and physicochemical parameters of floodwater of Omasi rice field in Anambra State, Nigeria were studied. Samples for the studies were collected at monthly intervals. The microalgae were studied using light microscopy and identified with taxonomic keys, text books and photograph materials from the internet. The physicochemical parameters and coliform content of the floodwater were analysed using the methods described by the American Public Health Association. Simple means of the parameters and percentages of the algal populations were calculated, while Pearson correlation (p ≤ 0.05) was used to check for significance of the relationships between the investigated parameters. A total of 12 algal taxa belonging to Chlorophyta (48.99%), Cyanophyta (32.89%), Euglenophyta (10.07%), and Bacillariophyceae (8.05%) were recorded in decreasing order of abundance. Water temperature ranged from 26-38 °C with mean of 33.3 ± 2.56 °C; colour ranged from 15-175 Hazen units with mean of 86.25 ± 33.19 Hazen units; depth of water ranged from 7-10.5 cm with mean of 9.38 ± 0.8 cm. Ranges of nitrates and phosphates with their respective means were 0.5-1.8 mg/l (0.86±0.31 mg/l) and 0.79-1.96 mg/l (1.18±0.28 mg/l). Omasi rice field supported the growth of diverse algal groups and species; this may be as a result of available nutrients and good climate as can be deduced from the correlation analyses. Omasi rice field is typical of tropical freshwaters and some tropical rice fields that have been studied in terms of microalgal diversities and some physicochemistry

Published: November 2021

Osmotic stress, oxidative stress and oxidation of essential macromolecules are common consequences of salinity stress that limit plant growth and productivity. Plants are known to evolve several strategies such as upsurge of antioxidant defence systems (ADS) and accumulation of osmolytes, so as to thrive under such conditions. In the present study, the effect of salinity stress (using irrigation method) on ADS of two cultivars (IT-99 and IT-288) of cowpea was examined. Plant samples (roots, young leaves and matured leaves) were harvested on day 21 of treatment with saline solution (100 – 400 mM NaCl). Antioxidant markers and osmolytes levels were quantified and compared with the controls (0.0 mM NaCl). The activities of superoxide dismutase, catalase, peroxidase and ascorbate peroxidase significantly increased (p<0.05) in the leaves, except for IT-288 where catalase activity significantly decreased (p<0.05) when compared to the control. On the contrary, catalase and peroxidase activities significantly decreased (p<0.05) in the roots of both cultivars. Largely, ascorbate, glutathione (GSH) and tocopherols levels increased as salinity increases, except for GSH in roots of IT-99, and leaves of IT-288. The amount of flavonoids detected in the same tissue were not significantly (p>0.05) different in all the salinity levels investigated. The level of proline increased at moderate salinity levels in all samples and at high salinity in roots of IT-99 and mature leaves of IT-288. For IT-99, levels of glycinebetaine significantly increased (p<0.05) at high salinity, but significantly decreased at similar levels in IT-288. H2O2 levels significantly increased in the roots but decreased (p<0.05) in leaves samples. Malondialdehyde concentration generally increased significantly (p<0.05) when compared with control. The findings of these study suggest that both cultivars were induced to express higher antioxidant activity and to a certain extent synthesis of more osmolytes.
Microbial production of histamine and the imperatives of processed food consumption
Authors: Ezema James Nnabuike , Agbo Esther Chinedu , Eze Emmanuel Aniebolam
Published: November 2021

Food processing and storage increase the value chain of food items, both for commercial purposes and for future use by peasant producers. The roles of lactic acid bacteria (LAB) and yeasts in the processing of dairy, brewed, bakery and traditionally fermented foods cannot be over-emphasized. These organisms improve the nutritional contents and organoleptic properties of these foods. However, certain undesired products, especially from protein-rich foods, notably, biogenic amines often characterize the process. This is usually a physiologic response by the organisms to the food environments such as pH, and is often influenced by temperature, time and salt concentration.  Histamine production during such a process often results in the accumulation of exogenous histamine in the foods, thereby constituting health hazards to the consumers. Histamine food poisoning affects virtually every system of the body due to the widespread physiological roles of histamine in the body, presenting a wide range of symptoms that make diagnosis difficult. More regulated scientific approaches should be adopted by food processors and handlers especially in the developing countries where technologies may not be available.
