Communicative approach to the languages’ learning as a way of speech competence’s formation by children with speech and mental retardation
Authors: KOLODYCH O.В.
Published: March 2023

The article deals with the process language learning as a means of social interaction, which is the result of the society’s demand formation for the latest researches in the field of psychology, sociolinguistics, correctional psychology; revealed a number of important issues to the problem of children with special educational needs speech and mental retardation. Using of the term «communicative competence» in the methodology of people with special educational needs providing support is directly related to the focus on communicatively oriented language learning, with the transfer of emphasis from the forms of speech phenomena to their function. The complication of communicative approach to language learning concerning in the process of communication and it is extremely unpredictable, out of linguistic analysis. The process of speech competence isan extremely complex and multicomponent phenomenon, so its analysis is not possible within one science. The process of children with language and mental retardation communication skills’ adoption will be intense, as it requires the development of methodologically sound recommendations forasmuch the latest research in special psychology, correctional pedagogy, neurolinguistics, sociolinguistics and more. The formation of people with special educational needs’ speech competence in is aimed to the skills’ developing in practical use of language structures with their communicative functions in familiar communication situations. Thus, for successful communication, students with language and mental retardation must assimilate not only knowledges of philological nature, general concepts of language, language structures, but also be able to apply knowledges in practice, because in communication it is impossible to separate phonetics, vocabulary or grammar. The formation of children with language and mental retardation speech competence opens important prospects for the correctional and developmental process in educational institutions. In particular, consideration of the phenomena of language not only from the point of view of language structures, grammar, vocabulary, and also performance of a number of communicative functions. The formation of speech competence does not mean abandoning the study of grammar or vocabulary, but significantly expands the possibilities of traditional teaching methods based on knowledge and use of language structures and determines the choice of language material in accordance with the purpose and objectives of communication.

The profound transformations of the national higher education system are the result of a combination of various factors. The process of creating a knowledge society puts the field of higher education at the center not only of the development of basic and applied science, the formation of future social and professionalelites, it makes it generally responsible for the interpretation, dissemination and use of new knowledge. The ethics of higher education, the values that underlie its scientific and educational activities, the principles and rules of relationships in each institution, in teaching staff, in relationships with students are the basis of the academic corporation’s ability to effectively self-regulate and meet society’s demand. Thus, conscious moral choice, concern for reputation become one of the main mechanisms of internal self-regulation of the professional community, determine its ethical priorities, balance of power and logic of professional communications. Academic integrity, as a certain social ideal, must counteract the excessive commercialization of universities, their intensive bureaucratization, which destroys not only the ability to fulfill their social mission, but also the logic of their existence. Violation of the principles of academic interaction, undermining of corporate solidarity and trust, reduction of professional involvement, low interest in the active work of the academic community - all this is a consequence of the limited autonomy of the academic space. The activities of the academic community can be effective only if it is based on a certain set of values that unite very different people into one team and give meaning to their joint activities. Academic honesty in this situation significantly affects the formation of common approaches to the organization of work, the definition of job competencies and trust, decision-making procedures, perception and resolution of conflicts, and so on. The article presents the basic principles and experience of implementing academic integrity in the educational and scientific space of Zaporizhia State Medical University in the framework of the implementation of European standards of higher education institutions in Ukraine.

Published: March 2023

Ultradiffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are difficult to detect because of their low surface brightness. In the Local Group a handful of UDGs have been found to date, most of which are satellites of the Milky Way and M31, and only two are isolated galaxies. It is unclear whether so few UDGs are expected. We address this by studying the population of UDGs formed in hydrodynamic constrained simulations of the Local Group from the HESTIA suite. For a Local Group with a total enclosed mass M
LG( < 2.5 Mpc) = 8 × 1012 M⊙, we predict that there are 12 ± 3 isolated UDGs (68% confidence) with stellar masses 106 ≤ M

(68% confidence) are detectable in the footprint of the Sloan Digital Sky Survey (SDSS). Accounting for survey incompleteness, we find that almost the entire population of UDGs in the Local Group field would be observable in a future all-sky survey with a depth similar to the SDSS, the Dark Energy Survey, or the Legacy Survey of Space and Time. Our results suggest that there is a population of UDGs in the Local Group awaiting discovery.
Une place à prendre ? Les « jeunes » dans les espaces publics d’un quartier en gentrification
Authors: Lancien Alice , Collectif Pop-Part
Published: March 2023

Cet article prend pour objet l’analyse d’une séquence ethnographique autour des différentes manières d’occuper les places assises dans un espace public du quartier en gentrification de La Chapelle à Paris. La description des compromis entre les différentes parties prenantes à travers le prisme des jeunes qui fréquentent cet espace permet de mettre en évidence les différentes catégorisations dont ces jeunes font l’objet et qu’ils sont eux-mêmes amenés à produire pour justifier et trouver leur place dans cet espace en transformation. L’approche empirique permet de discuter les travaux sur la gentrification en nuançant et complexifiant les analyses centrées sur des dynamiques d’éviction et de compétition pour l’espace. Les modalités de gestion du partage de l’espace ouvrent sur l’hypothèse d’une gestion « de fait » de ce dernier, qui s’apparenterait à une « infra-politique » de l’espace public urbain.
La vogue de l’art abstrait dans le catholicisme européen
Authors: Bœspflug François
Published: March 2023

Le catholicisme n’aurait-il pas cédé depuis quelque temps au charme ou au récent prestige socioculturel de l’art abstrait ? On peut se le demander face au nombre d’églises d’Europe occidentale où la loi du mur blanc s’est répandue, sinon imposée, avec le consentement des autorités ecclésiales soucieuses de « modernité », sans parler du nombre de tableaux d’église et de vitraux qui semblent s’être fait une loi ou un idéal d’être à chaque fois un triomphe des couleurs vives et un parfait désert iconique, sans que l’on puisse y repérer la moindre figure ni le moindre sujet iconographique identifiable.
Dossiers de carrière. Archives, individus et institution au ministère des Affaires étrangères (XVIII e -XIX e siècles)
Authors: Deloye Juliette
Published: March 2023

Dans la lignée du « tournant archivistique », les dossiers de carrière des agents du ministère des Affaires étrangères aux xviii e et xix e siècles sont considérés dans cet article comme un objet d’étude en soi. Plus précisément, ils sont envisagés comme le résultat d’opérations d’écriture et de mises en forme des archives par les acteurs, archivistes du ministère et individus faisant l’objet d’un dossier. La démarche consiste à appréhender ces dossiers comme des ressources, des moyens d’action par l’écriture dans le cadre des relations sociales qui construisent en permanence l’institution. Alors que les dossiers de carrière sont une source habituelle de la reconstitution des carrières, ce déplacement vers l’objet dossier permet de saisir des modalités du rapport entre individu et institution. Cela implique un regard rapproché au plus près des dossiers pour comprendre comment ils ont été constitués et de quels usages ils ont fait l’objet en leur temps. Il n’était donc pas possible de mener une étude quantitative. À partir de l’étude d’une poignée de dossiers, l’analyse attire l’attention sur un danger de naturalisation, qui consiste à les considérer a priori comme le lieu de l’archivage des carrières des fonctionnaires et comme un outil de rationalisation de l’administration. En revenant au moment de leur constitution, on observe la diversité de leurs contenus et les usages variés qu’en ont fait les acteurs. Ces dossiers archivent aussi tout autre chose que la carrière des agents.

Authors: de Oliveira Matthieu
Published: March 2023

Entre la fin du xvii e et le début du xix e siècle, la famille Panckoucke parcourt la distance sociale qui sépare la domesticité de la notabilité influente. Fort d’une parentèle importante et régulièrement renforcé par des alliances patrimoniales, le « Clan Panckoucke » conforte progressivement sa position sur la place de Lille, tant dans le monde de la librairie que dans celui du négoce. L’exercice de charges honorifiques puis de pouvoir au sein des institutions du commerce (Monnaie, Tribunal et Chambre de commerce) et de la franc-maçonnerie lilloise lui assure une visibilité sans pareille à la veille de la Révolution. Au-delà des étapes de cette ascension, cet article se propose d’analyser une stratégie familiale mise en œuvre avec succès.
L’intervention sociale auprès de mères seules en structure d’hébergement d’urgence
Authors: Derue Manon , Jeanselme Yoann , Lazzaroni Marie
Published: March 2023

L’article explore les spécificités de l’intervention sociale auprès de mères seules avec enfants accueillies dans des structures d’hébergement d’urgence. Il s’appuie sur une enquête qualitative menée entre mars et juin 2021 au sein des structures d’hébergement d’urgence gérées par le Samusocial de Paris. L’enquête rend compte de la façon dont les pratiques des intervenantes sociales auprès de ce public sont traversées par des rapports sociaux spécifiques de genre et d’interculturalité. L’intervention sociale en centre d’hébergement d’urgence vise plus spécifiquement l’accès des ménages au logement dit « autonome », conditionné par des critères multiples. Certains sont très précis : autorisation de séjour, ressources suffisantes, activité professionnelle, etc. D’autres sont plus implicites, liés à l’acquisition d’un ensemble de savoir-faire et savoir-être : gestion de son budget, respect des voisins, organisation de sa vie quotidienne avec les enfants, etc. L’accompagnement social proposé par les travailleuses sociales recouvre, auprès des femmes en situation monoparentales accueillies, des registres d’intervention divers et contradictoires. Ils peuvent être interprétés tantôt en termes de reproduction des rôles traditionnels de genre, tantôt en termes d’émancipation 2 .

Strong Determinism
Authors: Chen Eddy Keming
Published: March 2023

A strongly deterministic theory of physics is one that permits exactly one possible history of the universe. In the words of Penrose (1989), "it is not just a matter of the future being determined by the past; the entire history of the universe is fixed, according to some precise mathematical scheme, for all time.'' Such an extraordinary feature may appear unattainable in a world like ours. In this paper, I show that it can be achieved in a simple way and discuss its implications for metaphysics and philosophy of science, including natural properties, free will, explanation, and modality. First, I propose a precise definition of strong determinism. Next, I discuss its philosophical ramifications and a toy example. Finally, I provide a realistic example of a strongly deterministic (and simple) physical theory—the Everettian Wentaculus. A surprising consequence is that whether or not our world is strongly deterministic may be empirically underdetermined. 
Microfiltration Performance of α-Alumina Membrane for Removal of Glycerol from Biodiesel
Authors: Kusumocahyo Samuel P. , Maharani Nabilla S , Yusri Silvya
Published: March 2023

In biodiesel industries, the removal of glycerol from biodiesel is very important in the downstream process of the biodiesel production since the presence of glycerol in biodiesel causes diesel engine problems. Glycerol is commonly separated from biodiesel by extraction method using water, however, this method results in a vast amount of wastewater and requires a high energy consumption. In this work, a ceramic microfiltration membrane made of α-alumina was applied to remove glycerol from biodiesel. The microfiltration experiment was carried out using biodiesel containing various glycerol concentrations as the feed. For all investigated glycerol concentrations from 1000 ppm until 10,000 ppm in the feed, the membrane showed an excellent separation performance with rejection values of 91 to 99%. The profile of the permeate flux against the permeation time showed a flux decline because of the fouling phenomenon during the crossflow microfiltration experiment, and stable permeate fluxes were obtained after 2 h of permeation time. The result of this work showed that the separation process using the microfiltration membrane is a promising method to purify biodiesel instead of the conventional water washing method.

Published: March 2023

Tungsten (W) and Cerium (Ce) doped nanoTitanium oxide (TiO2) nanophotocatalyst were prepared by the sol-gel method and their photodegradation effect against atrazine herbicide were investigated. The doping of the nanocatalyst took place at 50 °C within a time interval of 120 minutes. The prepared gel was dried and calcined in the oven at 350 °C for 75 minutes. The XRD result revealed that the synthesized nanocatalyst was 16.7 nm in size with a mostly monoclinic structure. With FTIR spectra, characteristic peaks of TiO2 were found at 516 cm-1, Ti-O-Ce at 1104 cm-1, and W-O with a single bond at 1609 cm-1. Scanning electron microscope analysis revealed the surface morphology of synthesized nanophotocatalyst. The photocatalytic activity of synthesized nanocatalyst was tested on the degradation of atrazine herbicide (ATZ) under visible and UV light in a batch reactor. The efficiency of nanocatalyst was compared for effective utilization. About 46.5 % of photocatalytic activity was observed without UV light irradiation within 120 minutes. The photocatalytic activity of W-Ce co-doped TiO2 to degrade atrazine further increased up to 99.1 % when the solution was irradiated under UV light. Factors like pH, time, and concentration of nanocatalyst were optimized to check the photocatalytic activity of nanocatalyst on ATZ. It was concluded that nanocatalyst showed an efficient photocatalytic degradation at pH 6 within 120 mins time interval after exposure to UV light.

Authors: Nath Sanatan Kr. , Kalita Pradip Kumar
Published: March 2023

Copper sulphide quantum dots were synthesized by a simple chemical route using ammonia (aq.) as a complexing agent in PVA matrix. Copper acetate monohydrate and thiourea were used as precursors. The particle sizes as obtained from XRD results were found to be in good agreement with those of HRTEM. The UV-Vis. absorption and PL emission spectra exhibited a systematic blue shift of absorption and emission respectively confirming quantum confinement effect in the synthesized quantum dots. The band gap as estimated from Tauc-plot increased from 3.26eV to 3.92eV with change of concentration of complexing agent. The FTIR spectra exhibited Cu-S stretching peaks characteristic of CuS. Ionic contributions of the electrolytic ionic CuS solution as measured by a standard conductivity cell clearly showed the semiconducting behavior of the product material. The synthesized material may be exploited in fabrication of an optoelectronic device in UV-blue region.

Authors: Gupta Varun , Narang Savjot Singh , Gill Chiranjiv Singh , Selhi Pavneet Kaur , Gupta Manvi
Published: March 2023

Background:

Current severity assessment scores of acute pancreatitis (AP) include multiple variables, the results of which are available only after 48 h of admission. Red cell distribution width (RDW) and total serum calcium (TSC) are simple routine parameters related to inflammatory status and results of which are readily available.

Aim:

The aim of this study was to evaluate RDW and RDW: TSC within 24 h of hospital admission as predictors of outcome (severity and mortality) and intervention (medical/percutaneous drainage/surgical) required by patients of AP.

Materials and Methods:

All the patients diagnosed with AP at a tertiary care hospital were enrolled for the study. Values of RDW and TSC along with data regarding the treatment given were collected. Diagnosis and severity were defined according to the revised Atlanta classification 2012.

Results and Interpretation:

Cutoff value for RDW (area under the receiver operating characteristic curve [AUROC]: 0.997; P = 0.000) to predict the severity of AP was 16.25% (sensitivity - 100% and specificity - 97.1%,) (sensitivity - 100% and specificity - 97.1%, positive predictive value - 92.31%, negative predictive value - 100%, and Youden Index - 0.971), while that of RDW:TSC (AUROC: 1; P = 0.000) was 2.42 (sensitivity - 100%; specificity - 100%, positive predictive value - 100%, negative predictive value - 100%, and Youden Index - 1.00). Similarly, the cutoff value for RDW (AUROC: 0.947; P = 0.000) to predict mortality in AP was 17.20% (sensitivity - 100%; specificity - 87.4%, positive predictive value - 38.89%, negative predictive value - 100%, and Youden Index - 0.874) and that of RDW-to-TSC ratio (AUROC: 0.975; P = 0.000) was 2.9 (sensitivity - 100%; specificity - 96.6%, positive predictive value - 70%, negative predictive value - 100%, and Youden Index - 0.966).

Conclusion:

Our study found that RDW and RDW: TSC were quick, convenient, economic, sensitive, and dependable prognostic predictors of severity and mortality in patients with AP.
Pulmonary Hypertension, an Echo Assessment: Is it Arterial or Venous?
Authors: Sullere Vivek , Sullere Shivang , Khan Idris Ahmed , Goyal Rajendra G.
Published: March 2023

Introduction:

Pulmonary hypertension (PH) is characterized by pulmonary vascular remodeling, right heart failure, and reduced survival. PH can be PH without left ventricular (LV) dysfunction – pulmonary arterial hypertension (PAH) - (Dana point Class I) and PH with LV dysfunction – pulmonary venous hypertension (PVH) - (Dana point Class II). Whatever the underlying cardiac disease, the presence of PH in patients with heart failure is associated with poor prognosis. Right ventricular dysfunction by ventricular interdependence can cause LV dysfunction.

Objective:

We aim to provide a distinction between PAH and PVH by echocardiography.

Methods:

Retrospective cross-sectional single-center data of 1075 subjects having PH as defined by echocardiography was collected. These were segregated into mild, moderate, and severe categories. The same cohort of PH subjects was also segregated by E/e’ derived pulmonary capillary wedge pressure (PCWP) values. Echocardiographic measurements and effort tolerance in Mets were analyzed. Data for 707 normal subjects were taken from an earlier published study on normative echocardiographic measurements of healthy Indians.

Results:

Our findings show that PAH and PVH can be distinguished using PCWP value >15 mmHg obtained by applying Nagueh’s formulaon E/e’.

Conclusion:

We recommend that PCWP derived from E/e’ should be reported with pulmonary artery systolic pressure measurement to distinguish between PAH and PVH.
A Rare Case of Concurrent Ovarian Lesions: Ovarian Fibroma and Serous Cystadenoma in Contralateral Ovaries
Authors: Halder Ajay , Gautam Gargi , Dubey Pankhuri , Patel Shweta , Yadav Shakti Kumar
Published: March 2023

Ovarian stroma and surface epithelium develop from two different embryological primordia and give rise to tumors of distinct characteristics. The simultaneous presence of two kinds of ovarian tumors in one patient is rare. Concurrent presence of a large ovarian fibroma in one ovary, and a serous cystadenoma in the seemingly normal-looking contralateral ovary was found in a 55-year-old woman. The unusual coexistence of these tumors warrants a closer and longer follow-up of the patient. To the best of our knowledge, this is the fourth case to be reported in the literature. All surgically isolated tissues should undergo detailed histopathological examination, including normal-looking tissues which are excised as a part of the procedure.

Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease. Gastrointestinal manifesting as nausea, vomiting, and pain abdomen are not so uncommon in SLE flare. However, gastrointestinal intestinal vasculitis as an initial presenter of SLE is very rare. This case report narrated gastrointestinal vasculitis as an initial presentation of systemic lupus erythematous, which mimicked lithium toxicity in a patient of preexisting bipolar disorder who was on long-term lithium therapy. A 26-year-old female presented with abdominal pain and persistent vomiting for 2 months. On further workup, she was antinuclear, anti-Smith, and anti-ds-DNA antibody positive. The serum lithium level was found to be normal computed tomography angiogram of the abdomen suggestive of vasculitis. A final diagnosis of SLE with gastrointestinal vasculitis as an initial presenter was made. She was treated with high-dose corticosteroid, cyclophosphamide, and other supportive care. She improved dramatically and was discharged with an oral corticosteroid, hydroxychloroquine, and ramipril.

Published: March 2023

Background:

Flow characteristics of vinyl polysiloxane (VPS) impression materials are important determinants in the selection of impression materials for the fabrication of accurate indirect restorations.

Aims:

The purpose of this study was to determine the flow of three commercially available VPS impression materials at different time intervals using a shark fin device (3M ESPE, Seefeld, Germany).

Study Setting and Design:

This in-vitro study was carried out at the prosthodontics department of a dental institution.

Methods and Material:

The height of the shark fin produced by each impression material determined the rate of flow.

Statistical Analysis:

The data were analysed using one-way analysis of variance (ANOVA) and post-hoc Tukey's test (p-0.05).

Results:

Shark fin height of group A VPS impression material was significantly higher at 30 and 120 seconds compared to group B and group C VPS impression materials. Shark fin height produced by group B VPS impression materials at 60 and 90 seconds was significantly higher than the group C VPS impression material but non-significant compared to group A. At 120 seconds, there was no significant difference in the shark fin heights of all the tested materials.

Conclusion:

All the materials exhibited adequate flow characteristics within clinically acceptable limits.

Published: March 2023

Context:

The proliferation and differentiation of human periodontal ligament stem cells (hPDLSC) into other cell types are also mediated by mechanical stresses; they might offer therapeutic benefits in tissue regeneration and angiogenesis.

Objectives:

The study was planned to assess the proliferation, clonogenic potential, and osteogenic differentiation of human periodontal ligament stem cells (PDLSC) following the application of light and heavy orthodontic forces.

Materials and Methods:

A couple forces of 50 gm (light force) were applied on the 1st premolar on the one side and 250 gm (heavy force) on the contralateral side in the upper arch of patients requiring orthodontic treatment with extraction of all 1st premolars. After 30 days, periodontal tissues were scrapped from extracted teeth for the establishment of PDLSC in vitro. PDLC from the lower premolar teeth where no orthodontic force was applied acted as the control group. Morphology, viability, proliferating rate and population doubling time, clonogenicity, and alkaline phosphatase activity were analysed.

Result:

The osteogenic potential was confirmed by Alizarin red staining and the expression of the osteogenic markers by qRT-PCR. The morphology, growth kinetics, potency, and osteogenic lineage characteristics inferred the application of high force reduced the proliferative ability and osteogenesis of PDLSC, though the difference was not significant.

Conclusion:

The established PDLSCs demonstrated their MSC-like properties based on morphology, growth kinetics, colony forming ability, and AP activity. The culture-expanded PDLSCs showed their differentiation potential into osteocytes. The application of high force reduced the proliferative ability and osteogenesis of PDLSCs, variations were not significant.

Authors: Hema P , Balu Pratebha , Kumar Saravana , Haritheertham Gayathri , Thirumalai S , Ahila E
Published: March 2023

Background:

Recession is a mucogingival condition affecting teeth causing hypersensitivity. Although many techniques are there for recession coverage, semilunar vestibular incision technique (SVIT) is a novel procedure for management of multiple gingival recession in maxillary teeth.

Aim:

To evaluate the efficacy of root coverage in maxillary teeth with multiple gingival recession using SVIT.

Methodology:

Twenty systemically healthy patients were recruited with Miller's class I and II gingival recessions in maxillary teeth. Parameters such as recession height (RH), recession weight (RW), avascular surface area (ASA), width of keratinized gingiva (WKG), width of attached gingiva (WAG), and clinical attachment level (CAL) were measured at baseline three and six months post-surgery.

Results:

The outcome measures were statistically significant at baseline, three and six months. A reduction of 86% was achieved in terms of RH and RW. Gain in WKG and WAG as achieved at six-month follow-up was 31.5% and 55%, respectively. An 87% decrease in ASA was obtained and reduction in CAL was 82.4%. Between three and six months there was a significant increase in WAG.

Conclusion:

SVIT results in improved measures of attached gingiva on six-month follow-up.
'TT' (Tikku and Tikku) System

Published: March 2023

Several systems for designating and encoding teeth have been used in dentistry for more than 130 years.[1] In our profession, patients are the primary stakeholders. However, the prevailing tooth numbering system, like the Federation Dentaire Internationale (FDI), is designed focussing the clinicians and does not include the perspective of patients, who have little idea regarding the depicted number of the tooth to be treated, written on the prescription given to them. Our undergraduate students also often get confused during their clinical work regarding the designated four segments in the current FDI tooth numbering system. This sometimes results in misinterpretation, leading to clinical mishaps. This innovative TT (Tikku and Tikku) system has been designed to fulfil the requirement for a more simpler and coherent system that is self-reflecting and includes the perception of the patients or any other concerned non-dental professional so that they relate easily to this system. Named after its inventors, the TT tooth numbering system has a simple and unique design that can also be implemented for wide clinical and forensic applications.

Published: March 2023

Background:

In comparison to multiple file systems, recent advancements in single file retreatment systems had reduced the working time and ease of operation for clinicians.

Aim:

To compare the efficacy of retreatment systems compared with hand instrumentation, by evaluating their removal efficacy, time required for retreatment and assessment of canal transportation.

Methods and Material:

Forty premolars were instrumented using ProTaper Gold gold files. Post instrumentation, scan was taken, obturated using warm vertical compaction technique, and stored in artificial saliva for three months and randomly divided into four groups for retreatment. Hand instrumentation (Hi), Neoniti (Nn), Mtwo R (Mt), WaveOne Gold (Wg). Post retreatment, scan was taken. Teeth were sectioned longitudinally and photographed under the stereomicroscope. Retreatment time was recorded, and canal transportation was calculated.

Statistical Analysis:

The results were analyzed using one-way analysis of variance (ANOVA) followed by Tukey's post hoc test at 95% confidence level.

Results:

The retreatment time was significantly longer in the Hi group. Within the test groups, a significantly longer time has been taken by Wg (p < 0.05) compared to Mt and Nn. There was no difference in the canal transportation between the single file systems at 3 mm, 6 mm and 9 mm from the apex, there was statistically significant higher transportation for the Hi group at 9 mm from the apex (p < 0.05).

Conclusions:

All techniques were effective in removal of filling material with minimal canal transportation. Wg system was shown to increased time compared to Nn and Mt systems. Hi group was slowest with maximum canal transportation at 9 mm from the apex.

Ratol is a rodenticide (rat killer paste) that contains yellow phosphorus, a dangerous toxin that harms the gastrointestinal, hepatic, cardiovascular, and renal systems both locally and systemically. The liver is one of these that is most frequently injured, and the most terrifying result is acute liver failure with coagulopathy. A 25-year-old male who is a known case of epilepsy and was on medication was brought to the Emergency Department by his mother with an alleged history of consuming approximately 15 g of Ratol paste mixed in water 5 days before presentation to our hospital at around 5 pm at his residence. The patient sustained nausea and vomiting during the following day of consumption and was treated for the same in a nearby hospital. The main element in lowering morbidity and death is the provision of effective and timely supportive care.

Published: March 2023

Introduction:

Gastro-esophageal reflux disease (GERD) is a condition characterized by the reflux of stomach contents into the esophagus, causing unpleasant symptoms and/or consequences like heartburn and acid regurgitation. GERD in the student stages can hurt their quality of life, college attendance, everyday activities, and overall well-being of the individual.

Materials and Methods:

This is a cross-sectional study that was conducted among medical students of a tertiary care setting from August 2021 to October 2021 for a three-month duration. A convenient sample of 458 participants from all the years of MBBS was included in this study.

Results:

A total of 458 medical students were made part of this study of which most of them (58.9%) were females and 41.1% were males. The average age among the study participants was 22 ± 2.3 years (range of 18–27 years). The average BMI of the individuals was 23.48 (range 14.58–32.41), with the majority (54.8%) of them having a normal BMI.

Discussion:

In our study, we found that the prevalence of GERD in the medical students of a rural Indian tertiary care setting was 24.2%, and was observed that irregular meal timings and consuming coffee and soft drinks are the crucial risk factors for developing GERD in the medical students in comparison to the general population.

Conclusion:

Medical students should be trained on proper eating habits, maintaining ideal body weight, good sleep hygiene, and avoiding drinking alcohol and smoking to lessen the burden of GERD.
Hemiarthroplasty in geriatric population with neck femur fracture: A retrospective study of 43 cases

Published: March 2023

Introduction:

Hip fractures in the elderly have represented a major public health concern. Studies have shown that over 90% of the patients having these fractures are people of more than 50 years. These fractures have been classified according to their anatomical location into the neck of femur fracture, intertrochanteric fracture, and subtrochanteric fracture. The neck of femur fractures is associated with high mortality in the elderly compared to young adults. Surgical treatment is an established gold standard, with the option being osteosynthesis and hip replacement. Hemiarthroplasty is one of the gold-standard treatments chosen for the geriatric age group and has yielded universally acceptable results.

Materials and Methods:

The study evaluates the clinical, radiological, and functional outcomes of hip hemiarthroplasty in elderly with fracture neck of the femur Data of patients above 60 years who were operated on for fracture neck of the femur by bipolar hemiarthroplasty from May 2018 till December 2021were retrieved from the Medical Records Department of SCL Municipal General Hospital, affiliated to NHL Municipal medical college. The patients fitting the inclusion criteria were selected for the study. The sample size was calculated to be 43. Data were collected from the inpatient files, and then patients were asked to complete the questionnaire form during the final follow-up. All the patients were evaluated clinically and radiologically during the follow-up, and the functional outcome was assessed using the Harris Hip Score. Thirty-five patients had a domestic fall as the mode of injury. The lateral decubitus position of all patients was used during the operation that was performed using the Southern Moore approach. Forty patients received cemented femoral stems; the remaining three received press-fit ones.

Results:

The average age was calculated to be 71.86 years with the male-to-female ratio of 1: 1.15 with an average follow-up of 12.7 months. Eight patients had acetabular erosion at the end of 1 year. There was no femoral stem malalignment or aseptic loosening at the final follow-up. Nine patients had excellent Harris Hip scores, and five had fair scores. The remaining 29 patients had good Harris hip scores. Bipolar hemiarthroplasty has served us well in the study. Forty-one patients were able to get back to their preinjury functional level. Only one patient reported major pain in the hip at the final follow-up. In this study, there was no incidence of dislocation or revision surgeries.

Conclusion:

The present study modular bipolar hemiarthroplasty provides better pain relief with early mobilization and a good level of return to daily routine activities with minimal complications.

Published: March 2023

Background:

Breast Imaging Reporting and Data System (BI-RADS) classification for breast lesions was proposed for uniformity in categorizing breast lesions. While BI-RADS 1, 2 and 4–6 categories are straightforward, BI-RADS 3 is an intermediate category lesion with significantly different meanings and findings for mammography, ultrasound, and magnetic resonance imaging and is diagnostically challenging. Our study aims to determine the frequency and the malignancy rate of BI-RADS category 3 lesions detected on ultrasound breast and digital X-ray mammography by doing follow-ups at 6, 12, and 24 months of imaging.

Materials and Methods:

This ambispective study was conducted in the Department of Radiodiagnosis, Jawaharlal Nehru Medical College and Hospital, Aligarh Muslim University, Aligarh, from October 2020 to October 2022, which included 55 patients referred for digital X-ray and breast ultrasound. All BI-RADS category 3 in the initial sonomammography and digital X-ray mammography were included in the study and were followed up for final diagnosis and outcome either by pathological analysis or follow-up using sonomammography and digital X-ray mammography for a maximum of 24 months.

Results:

Fifty-five patients were categorized into the benign or malignant category from the results of tissue diagnosis or via follow-up. Fifty-four patients (98.18%) showed benign lesions, and one (1.82%) got malignant lesions. In the majority, 31 (56.36%) patients, the mean follow-up time was 6 months, followed by 12 months 10 (18.18%). Follow-up was 24 months in only 1 out of 55 patients (1.82%). The mean value of time to follow-up (months) of study subjects was 6 ± 4.6 with a median (25th–75th percentile) of 6.

Conclusion:

Short-term interval follow-up in BI-RADS category: three patients are enough to detect early breast malignancy, and this will avoid unnecessary tissue diagnosis (invasive procedure) in benign lesions. In our study, the malignancy yield in the follow-up of BI-RADS 3 was 1.82% (<2%).

O direito à saúde é previsto constitucionalmente nos arts. 196 e 226, §7º, ambos da Constituição Federal; nesse contexto a Lei n.º 9.236/96, que regula o planejamento familiar, estabeleceu critérios para a esterilização. O método é o indutivo; o marco teórico consiste no capítulo “O Nascimento da Medicina” da obra Microfísica do Poder de Michel Foucault. Conclui-se que a lei n.° 9.263/96 colocou sob o signo da legalidade a desapropriação do corpo humano ao restringir, pela imposição de critérios abstrusos, o acesso ao procedimento médico de esterilização.
