La psychologie dans la correspondance entre Althusser et Sève
Authors: Morilhat Claude
Published: September 2023

Cette correspondance offre une contribution importante à la connaissance des débats qui traversent la pensée marxiste en France au cours de la deuxième moitié du xx e  siècle. À travers la question de la psychologie se trouvent en jeu les divergences fondamentales entre les deux philosophes. Dès le début de leur relation amicale apparaissent entre eux des divergences non explicitées au sujet de la psychologie, mais après un rapprochement temporaire et superficiel (en 1967), les oppositions théoriques se verront clairement formulées.
En quel sens la « communauté » est-elle une problématique du confucianisme ?
Authors: Wang Pei
Published: September 2023

Le mot 社群 ( she qun , communauté, au sens de la Gemeinschaft allemande) n’était certes pas une problématique traditionnellement confucéenne. La compréhension éthique générale de la Chine antique reposait sur 三纲五常 ( san gang wu chang  ; les trois disciplines et les cinq justes relations interpersonnelles). Les religions, associations et académies non dominantes étaient plus proches du concept de communauté. Les concepts occidentaux modernes de la sociologie ont été introduits pour la première fois en Chine à la fin du xix e  siècle, mais les intellectuels les comprenaient certes différemment, en fonction des valeurs traditionnelles locales, et en réponse à la nécessité de renforcer l’État chinois. L’idée moderne de communauté et le concept de société avec lequel on la contrastait n’ont été popularisés en Chine qu’à l’époque de l’industrialisation, à partir de la fin des années 1970.
L’innovation et la transformation de l’économie collective en Chine : une analyse du processus d’urbanisation à travers le village de Liede à Canton
Authors: Liao Liao , Huang Chunli
Published: September 2023

En tant qu’acteur important dans la gouvernance rurale, les organisations économiques collectives jouent un rôle primordial dans le processus d’urbanisation rurale et constituent un point de vue important pour comprendre l’évolution des relations entre zones urbaines et zones rurales en Chine. En même temps, ces organisations constituent le noyau de la communauté locale, qui représente les individus sur la base d’une même appartenance ethnique, par proximité locale ou par proximité de valeurs communes, voire par proximité économique. Ainsi, les individus partagent une forme de cohésion solidaire, fondée affectivement. Toutefois, au fur et à mesure du développement économique et social, le système, la notion et la nature de l’économique s’évoluent et les valeurs des individus changent, tandis que ces organisations s’adaptent mal au changement économique et social, ce qui provoque la controverse de la société chinoise rurale au cours de la modernisation de la Chine. S’appuyant sur une recherche de terrain et l’analyse des données du village de Liede à Guangzhou, cet article porte sur le processus d’intégration urbaine-rurale du village urbain et explore l’intégration du village urbain dans la ville à travers l’organisation économique collective de Liede, notamment Liede Economic Development Co., Ltd. Dans ce processus, il existe des contradictions entre le rôle du village et le rôle des organisations économiques collectives. Les organisations collectives ont des fonctions économiques, mais elles assument toujours aussi des coûts importants concernant des fonctions publiques telles que la sécurité sociale. On verra que la réforme de la « séparation politique et économique » après la période de l’économie planifiée des années 1980 n’a pas eu d’effet au niveau local. L’évolution du rôle des organisations économiques reflète la mutation de l’économie chinoise, c’est-à-dire, le passage de l’économie communiste à l’économie de marché. Toutefois, l’engagement solidaire existe toujours dans l’économie collective et celle-ci essaie de limiter la cupidité et soutenir l’intérêt commun au lieu de le marginaliser, ce qui constitue un caractère spécifique de l’économie collective en Chine.

Indicateurs de vigilance en chirurgie : définition et utilisation pour l’autorisation des activités de soin
Authors: Mentec Hervé , Legris Candice , Cabarrot Philippe , May-Michelangeli Laetitia
Published: September 2023

Dans le cadre de la rénovation des décrets d’autorisation d’activités chirurgicales, le ministère des Solidarités et de la Santé a saisi la Haute Autorité de santé (HAS), en collaboration avec l’Agence technique de l’information sur l’hospitalisation (Atih), pour définir des indicateurs de résultat mesurés à partir du Programme de médicalisation des systèmes d’information de l’hospitalisation en médecine, chirurgie, obstétrique et odontologie (PMSI-MCO) permettant une alerte en matière de qualité et de sécurité des soins pour les activités de chirurgie. Ces indicateurs ont pris le nom d’« indicateurs de vigilance » dans les textes législatifs encadrant cette réforme. Une recherche documentaire réalisée par la HAS a permis d’identifier 1 019 indicateurs de résultat. Parmi ceux-ci, 198 ont été considérés comme mesurables à partir du PMSI-MCO par l’Atih. Ces indicateurs éligibles ont ensuite été soumis aux parties prenantes afin d’en sélectionner cinq par spécialité sur la base de leur pertinence clinique et de leur pertinence pour l’amélioration de la qualité et de la sécurité des soins. Compte tenu de l’existence d’ex aequo et de doublons, 77 indicateurs ont ainsi été définis, dont 15 spécifiques à une spécialité et 59 applicables à toute chirurgie. Ces indicateurs portaient principalement sur la mortalité, les réadmissions et les complications. Par ailleurs, des préconisations sur les modalités de leur mise en œuvre ont été proposées. La définition des indicateurs de vigilance constitue la première étape des travaux. Dans un second temps, un nombre restreint d’indicateurs sera développé et validé par l’Atih, en définissant notamment leur périmètre (populations cibles, critères d’inclusions et d’exclusions…), les ajustements à appliquer et les seuils d’alerte.
Les commentaires libres du questionnaire e-Satis et les plaintes ont-ils la même valeur informative au centre hospitalier universitaire de Clermont-Ferrand ?
Authors: Bufferne Alixia , Belgacem Bénédicte , Ezzitouni Jihad , Gerbaud Laurent
Published: September 2023

Contexte et objectifs. L’enquête nationale de satisfaction e-Satis, par la Haute Autorité de santé, donne la parole aux patients, en les laissant s’exprimer librement à la fin du questionnaire. Aucune analyse régulière des commentaires n’étant effectuée au centre hospitalier universitaire de Clermont-Ferrand, la question de sa faisabilité s’est posée. L’objectif principal de cette étude est l’analyse des thématiques de ces commentaires en les comparant aux thématiques des plaintes reçues. Méthode. Nous avons réalisé une analyse descriptive des thématiques retrouvées dans les verbatims issus d’e-Satis grâce à une triangulation et à la modification d’un thésaurus existant, jusqu’à saturation des thématiques. Nous avons ensuite regroupé les différentes thématiques selon leurs sens en commun. Nous avons comparé statistiquement les thématiques retrouvées dans le questionnaire e-Satis et celles des plaintes. Résultats. 542 patients ont laissé au moins un commentaire (63,7% des patients ayant rempli le questionnaire). Une remarque positive sur deux concerne la satisfaction vis-à-vis du personnel (sans préciser lequel). Le thème négatif le plus fréquent (34,6% des remarques négatives) concerne le déroulement de la prise en charge. Nous avons pu identifier de nombreux thèmes plus précis. Les thématiques des plaintes sont réparties différemment de manière significative. Discussion et conclusion. Cette étude permet d’identifier de nombreux axes d’amélioration pour la satisfaction du patient et confirme que les commentaires libres sont complémentaires aux plaintes. Les ressources nécessaires à un tel travail régulier restent difficiles à assumer individuellement par établissement et pourraient être aidées par un logiciel auto-apprenant.
Transformation des entreprises et tiers de confiance : la mutation de la chaîne de confiance dans le management des entreprises
Authors: Pluchart Jean-Jacques
Published: September 2023

Cette recherche soulève la problématique de la perception par les auditeurs légaux et les vérificateurs sociétaux, des mutations - en cours et souhaitables - de leurs missions, de leurs compétences et de leurs méthodes, destinées à préserver ou à renforcer leur statut de tiers de confiance au service de l’entreprise. Elle mobilise une méthodologie qualitative à la fois exploratoire et originale, basée sur un sondage et sur des entretiens semi-directifs. Elle révèle la diversité des facteurs qui viennent modifier les conditions d’exercice des métiers du chiffre. Ces facteurs sont de nature institutionnelle (le foisonnement réglementaire et normatif, le relèvement des seuils d’audit obligatoire), technologique (l’émergence de l’IA et de la blockchain ) et organisationnelle (la multiplication des contrôles, audits et vérifications internes et externes à l’entreprise).
Impact of Small Incision Lenticule Extraction for High Myopia on Intraocular Pressure Measurements With Pneumotonometry
Authors: Mohr Kjeld M. , Gyldenkerne Anders N. , Hjortdal Jesper Ø.
Published: September 2023

Purpose:

To evaluate the medium-term impact of small incision lenticule extraction (SMILE) on air-puff tonometry (APT) and how it may be corrected.

Methods:

In this controlled prospective study, 69 eyes from 69 patients treated with SMILE for high myopia (mean: −7.22 diopters) were included. Central corneal thickness (CCT), spherical equivalent refraction (SEQ), corneal power, and intraocular pressure (IOP) (assessed by APT) were measured before and 3 months after surgery.

Results:

The measured IOP decreased significantly after SMILE surgery (mean: −6.43 mm Hg), indicating a significant underestimation of the true IOP by APT. There was a significant correlation between change in SEQ, CCT, and apparent IOP. Correcting the apparent IOP measurement by applying a multiple regression correction did not provide significantly better estimates compared to adding 6.4 mm Hg to the measurement.

Conclusions:

This study showed that previous SMILE surgery should be considered when interpreting APT measurements, because the measurements underestimate the true IOP. Multiple regressions cannot estimate the true IOP with certainty. For screening purposes, adding 6.4 mm Hg to the apparent IOP of a patient treated for high myopia may be sufficient.

A collaborative prediction approach to defend against amplified reflection and exploitation attacks
Authors: Prasad Arvind , Chandra Shalini , Atoum Ibrahim , Ahmad Naved , Alqahhas Yazeed
Published: September 2023

An amplified reflection and exploitation-based distributed denial of service (DDoS) attack allows an attacker to launch a volumetric attack on the target server or network. These attacks exploit network protocols to generate amplified service responses through spoofed requests. Spoofing the source addresses allows attackers to redirect all of the service responses to the victim's device, overwhelming it and rendering it unresponsive to legitimate users. Mitigating amplified reflection and exploitation attacks requires robust defense mechanisms that are capable of promptly identifying and countering the attack traffic while maintaining the availability and integrity of the targeted systems. This paper presents a collaborative prediction approach based on machine learning to mitigate amplified reflection and exploitation attacks. The proposed approach introduces a novel feature selection technique called closeness index of features (CIF) calculation, which filters out less important features and ranks them to identify reduced feature sets. Further, by combining different machine learning classifiers, a voting-based collaborative prediction approach is employed to predict network traffic accurately. To evaluate the proposed technique's effectiveness, experiments were conducted on CICDDoS2019 datasets. The results showed impressive performance, achieving an average accuracy, precision, recall and F1 score of 99.99%, 99.65%, 99.28% and 99.46%, respectively. Furthermore, evaluations were conducted by using AUC-ROC curve analysis and the Matthews correlation coefficient (MCC) statistical rate to analyze the approach's effectiveness on class imbalance datasets. The findings demonstrated that the proposed approach outperforms recent approaches in terms of performance. Overall, the proposed approach presents a robust machine learning-based solution to defend against amplified reflection and exploitation attacks, showcasing significant improvements in prediction accuracy and effectiveness compared to existing approaches.

Using Blockchain to Decentralize Product Development
Authors: Gatti Rathishchandra Ramachandra , Singh Chandra
Published: September 2023

Digital technologies such as IoT, Cloud, and mobile computing have enabled product innovation, consumer interactions, and efficiency. Blockchain technology has altered how organizations work, providing a paradigm shift in resilience, security, and efficiency. Blockchain enables agile value chains, product innovations, and technological fusion. Every company considers research and product development expensive. Investments are risky, especially if the new product version differs considerably from their current portfolio. Firms must share high investment risks through joint ventures or cooperative product development. However, for collaborative product development, trust and transparency must be vital. Decentralizing design data interchange, funding, and marketing with correct crediting of contributions is one of the methods for multiple-organization collaboration. Blockchains technologies can be employed for such collaborations. This study explores how blockchain can decentralize product development worldwide to meet security, scalability, efficiency, and incentivization criteria.

Authors: Guan Chong , Ding Ding , Gupta Priyanka , Hung Yu-Chen , Jiang Zhiying
Published: September 2023

This chapter investigates previous research themes and trending topics related to ChatGPT through a comprehensive analysis of the literature. An automated technique (web-scraping) was deployed to retrieve and compile all existing journal papers, conference proceedings, and book chapters from major publisher databases in the related fields, and the abstracts of the selected articles were quantitatively analysed using a probabilistic topic modeling procedure – the latent Dirichlet allocation (LDA) approach. Based on the topics identified by the LDA model utilizing their most representative terms, 10 research themes and corresponding keywords have emerged in the results. The overall findings indicate that research efforts in this field have primarily focused on performance, user disposition, application practices, and ethical and privacy concerns. A conceptual framework that delineated the relationships between the research issues and opportunities for future research on ChatGPT is also introduced.
Influence of Socio-Demographic Factors on Entrepreneurial Intentions Among Senior Secondary School Adolescents in Osogbo Local Government, Osun State, Nigeria
Authors: Olulani Alebiosu Yejide , Adekemi Odede Olaitan
Published: September 2023

This study investigated the influence of environment and role model as social factors influencing entrepreneurial intentions in adolescent students. This study dwelt on the theory of planned behaviour which predicts intentions. The study adopted a survey research design. A simple random sampling technique was used to select a sample of two hundred (200) adolescents from four senior secondary schools in Osogbo local government area of Osun State, Nigeria. A self-structured questionnaire titled Dominant Environment, Role Model and Entrepreneurial Intention (DERoMEi) with reliability index of 0.69 was adapted for the study. Data collected were analysed using the Analysis of Variance (ANOVA) statistical method. The result confirmed that: entrepreneurial intentions of adolescents is favourably and positively influenced by the adolescents’ dominant environment (f=7.696, p<0.05); role model had no impact on entrepreneurial intention of students (f=2.523, p>0.05); gender sensitivity played a role in the prediction of entrepreneurial intentions of adolescents as males tended to conceive entrepreneurial intention more than females (f=15.596, p<0.05). Recommendations given included that: entrepreneurship engagement should be promoted in communities to encourage wider acceptability by adolescents; parents and care givers who are entrepreneurs should encourage their children to acquire entrepreneurial skills alongside their senior secondary school education; more female adolescents should be encouraged to venture into entrepreneurship despite their educational engagement in senior secondary schools.
A Bibliometric Analysis of Data Governance Research: Trends, Collaborations, and Future Directions
Authors: Abeykoon B. B. D. S. , Sirisena A. B.
Published: September 2023

Research on data governance has been shaped by an excessive number of articles published in recent decades. The research study used bibliometric techniques to examine 757 journal articles in the Scopus database and it shows a dynamic growth of the topic in the selected years from 2012 to 2022. The methodology is based on the performance analysis technique and science mapping technique in bibliometric analysis. The results explore the contribution to the domain in terms of authors, sources, and countries, disclose the network between the countries and scholars relevant to the publications, and provide research areas that need more attention which drives data governance. Data protection, data access, artificial intelligence, data management, cloud computing, blockchain, and data transformation are among the areas where there is a lack of information, therefore academics should pay closer attention to them in the future. The authors observed that a wide range of disciplines have been used to address the topic of data governance. The study lays the foundation for academics, practitioners, and policymakers to conduct more future research and leads to advancing data governance research.
Usefulness of knowledge in anatomy of the internal iliac artery in its ligation during life-threatening pelvic haemorrhages
Authors: Dodampahala S. H. , Chandrasena Lal , Abeysuriya Vasitha
Published: September 2023

Introduction: Post-Partum haemorrhage is a significant cause of maternal mortality. Bilateral internal iliac artery ligation is a life-saving procedure to control massive obstetric and gynaecological haemorrhages. Bilateral internal iliac artery ligation results in toning down the pulsatility making the arterial flow a slow venous flow encouraging the clot formation of the damaged pelvic vessels. This study assesses the retroperitoneal anatomy and regional variations of the internal iliac artery.Methods: The study was based on examining 45 pelvic halves (23 right sides and 22 left sides), which were dissected during the gross anatomy laboratory at the faculty of medicine, Ragama, University of Kelaniya, from 2020 -2023. There were all adult pelvises. The internal iliac artery and its major branches were carefully dissected and examined. Adachi classification was used to classify the distribution pattern of the internal iliac artery. The study was done on the donated cadavers, and the nature of the study did not warrant any special ethical clearance. No conflict of interest.Results: No anatomical deviation has been noted with regard to the levels of division of aorta, common iliac artery, the division into internal and external iliac arteries and the division of anterior and posterior branches of the internal iliac artery from that of classical anatomical literature. It was also noted that there had been no significant deviation of anatomical relations with regard to the structures as described in the internal lilac artery in our study. In our study, Type Ia was found in 35/45 (78%) of the specimens, Type IIa in 3/45 (6%), Type III in 7 (16%), and no specimens were found with Type IV and. Type V.Conclusion: Our study showed no significant anomalies of the pelvic anatomical structural relations to the internal iliac artery. The type Ia branching pattern was found to be the commonest.

Published: September 2023

We report the case of a 40-year-old woman with a history of an opioid use disorder who presented to our emergency department complaining of palpitations, chest pain, and headache after the intramuscular injection of an ophthalmic solution containing tropicamide and phenylephrine (Visumidriatic Phenylephrine® 100 mg/mL + 5 mg/mL, Visufarma S.p.A., Italy) a few hours earlier for a voluntary purpose. She developed cardiac toxicity with hypertension, tachycardia, and high levels of high-sensitivity cardiac troponin I, which required continuous cardiac monitoring for 48 hours with complete resolution of the cardiac damage without complications. Based on the current literature, this is the first reported case of cardiotoxicity induced by an ophthalmic solution of tropicamide and phenylephrine used intramuscularly for voluntary purposes.
Consequences of sagittal malalignment following reconstruction of complex tibial plateau fractures
Authors: Sharaby Mohamed M F , Abuheif Mohamed
Published: September 2023

Purpose

Changes of posterior tibial slope following complex tibial plateau fractures have not been fully evaluated in the literature. Some studies indicated that arthritic changes that occur following tibial plateau fracture were more correlated to deformity and instability rather than articular surface step-off.

The aim of this study was to evaluate the midterm clinical effects following changes in the posterior slope that might be associated with reconstruction of complex tibial plateau fractures.

Patients and methods

This retrospective cohort study was carried out on 112 patients operated by internal fixation following complex tibial plateau fracture within 4 weeks of the incident of injury. Modified Rasmussen score was used for both clinical and radiological evaluations in addition to final evaluation of the slope by computed tomography scan. The Knee Injury and Osteoarthritis Outcome Score was used for subjective evaluation of the clinical results, and Kellgren–Lawrence radiological grading was used for osteoarthritis grading.

Results

The mean flexion was 118.8 ± 13.0° (range, 90–140) in GI and 119.7 ± 13.5° (range, 70–140) in GII, and the mean extension deficit was 1.6 ± 2.7° (range, 0–10) in GI compared with 1.9 ± 2.9° (range, 0–10) in GII. The mean clinical Rasmussen score was 26.3 ± 2.9 (18–30) in GI and 26.1 ± 3.2 (16–30) in GII. The mean Knee Injury and Osteoarthritis Outcome Score in GI was 79.3 ± 5.1 compared with 77.7 ± 5.6 in GII. According to Kellgren–Lawrence grading system for osteoarthritis, there were 23 patients with grades 2 and 3 osteoarthritis in GI compared with 32 cases in GII. The study showed a statistically significant correlation between decreased tibial slope and limitation of extension. Otherwise, there were no statistically significances between changes of tibial slope and stability, pain, or the overall postoperative knee score.

Conclusion

Changes in posterior slope angle of the tibial plateau during fracture fixation is an important factor that can significantly affect range of motion, particularly extension. Osteoarthritis is higher in patients with disturbed posterior slope; however, a larger sample is needed for possible significance.

Authors: Samy Mohamed
Published: September 2023

Objective

To evaluate the results of fixation of intra articular calcaneus fracture using Sinus Tarsi Approach, bone block substitute, and screws fixation.

Background

Minimal invasive techniques for treatment calcaneus fractures have developed to overcome soft tissue complications associated with the traditional lateral approach. Sinus Tarsi approach has the advantage of visualization of posterior part of subtalar joint.

Methods

All patients underwent preoperative calcaneal lateral and axial radiographs and CT scan of the injured foot. The injured type was graded according to the Sanders classification on the basis of the CT scan findings.

Bohler and Gissane angles were measured as anatomical parameters before surgery. Sinus Tarsi Approach was done for all patients, in addition to use of percutaneous screws fixation and bone block graft substitute.

Results

A total of 17 patients were included in our study. The mean age was 37.8 years. At the end of follow-up, radiological evaluation was done by measuring the Bohler angle and the angle of Gissan. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle/hindfoot score was calculated at the end of the follow-up for all cases. Excellent results were found in7 patients, good results in 8 patients and fair results in only 2 patients. There was a statistically significant improvement of Bohler angle at the end of the follow-up.

Conclusion

Treatment of intra articular calcaneal fractures using Sinus Tarsi Approach with a bone block substitute and screws can provide satisfactory clinical outcomes.

Authors: Amr Ibrahim , Mohamed Ghandour Tarek
Published: September 2023

Purpose

To assess the effect of arthroscopic rotator cuff repair on sexual function, desire, and satisfaction, in addition to the shoulder function.

Methods

We did arthroscopic rotator cuff repair for 55 sexually active married individuals with rotator cuff tears. Shoulder and sexual function were assessed using: 1- the Constant-Murley score (CMS), 2- two visual analog scales (VAS) questionnaires, one to evaluate pain level during daily activities and the second to assess the pain level only during sexual activity, 3- Change in Sexual Functioning Questionnaire (CSFQ), 4- Sexual Desire Inventory (SDI) Questionnaire, 5- the Index of Sexual Satisfaction (ISS) Questionnaire, and 6- the study-specific short questionnaires. Assessment parameters were done before surgery and at 1 month (1M), 3 months (3M), 6 months (6M), 12 months (12M), 18 months (18M), and 24 months (24M) after surgery.

Results

Only 49 subjects were included in the final analysis (6 were excluded from the last follow-up). 77% of the study subjects found that their sexual life was affected by their shoulder condition, with 65% reporting that this was due to increased pain.75% needed to adjust their sexual position to accommodate their shoulder problem. 55% found that below the partner position is the most comfortable position during the sexual act. Additionally, we found a significant improvement over time in the CMS score, two VAS questionnaires, CSFQ, and ISS.

Conclusion

Arthroscopic rotator cuff repair improved shoulder function, pain level, sexual function, satisfaction, and mobility during sexual engagements. it did not affect the level of sexual desire.

Authors: Daher Mohammad , Ghoul Ali , Salameh Bendy-Lemon , Youssef Bryan , Sabbagh Joanna , Zalaquett Ziad , Roukoz Sami
Published: September 2023

Mass casualty incidents (MCI) are rare, large-scale events that result in heavy damage to people and infrastructure. These types of incidents result in a high influx of patients in local hospitals. In Beirut, this was witnessed on the 4th of August. A massive explosion took place in Lebanon’s capital city Beirut. Although Hotel-Dieu de France Hospital was damaged, it played a crucial role in the management of numerous injured, especially in the orthopedics department. Six months later, the hospital contacted all patients that had been hospitalized during that night and the following 2 days for musculoskeletal injuries. The contact was done for feedback purposes as the event was considered one of the largest non-nuclear explosions in international history. Accordingly, most of the patients that were contacted gave a credible and positive rating. There were few who had suggestions for management improvement. MCIs are rare, but it is crucial to be prepared to face any edging situation. Having effective communication and an organized plan in any risk management process are essential tools to foster for the well of the community and to scale down the losses of the locals in the area.
Metacarpals and phalanges malunion: a narrative review
Authors: Daher Mohammad , Ghoul Ali , Salameh Bendy-Lemon , Ghanimeh Joe , Sabbagh Joanna , Zalaquett Ziad , Roukoz Sami
Published: September 2023

Malunions are fractures that have healed with a deformity. Multiple abnormalities can coexist, but only one usually takes the lead causing symptoms, such as bone shortening, finger scissoring, etc. It is mainly caused by insufficient reduction. Malunions of the metacarpals are usually apex dorsal, while malunions of the phalanx tend to angulate volarly. Each patient with malunion should be assessed individually and treated conservatively if there is little to no functional impairment. Surgeries can be used to treat individuals with angular and rotational deformity.
Augmentation plates and bone grafting for treatment of nonunited long bones fractures fixed by intramedullary nails
Authors: Metwally Osam Mohamed , Elkady Reda Hussein , Shehata Ehab Mohamed
Published: September 2023

Background

A delayed union was defined as when the fracture fails to unite within the expected time. Delayed union becomes nonunion when the fracture healing stops (at least 6 months). Intramedullary nailing has proven to be a good treatment option in the management of long bones fracture. The aim of this study is to obtain union in nonunited long bones fractures fixed previously by intramedullary nails by using of augmentation plating and bone grafting to obtain the best outcome.

Patients and methods

The study included 18 patients of nonunited long bones fractures fixed previously by intramedullary nails treated with augmentation plating and bone grafting with maintaining the nail in situ. Full history, clinical and radiological examination were performed. All subjects gave their informed consent prior to their inclusion in the study. Eight cases with femoral fracture nonunion were performed through the lateral approach of the femur. Seven cases of tibial fracture nonunion were performed through the anterior approach of the tibia, Three cases of humeral nonunion was performed using the posterior approach of the humerus. In the postoperatively follow-up, function was assessed using Dash score and Lower extremity functional score.

Results

There was an excellent improvement for bone union occurred to 94.4% of studied patients. Furthermore lower extremities function percent ranged between 92.5-100 with mean±SD 98.1 ± 2.56, and humerus Dash score ranged between 4.16-6.66 with mean±SD 5.41 ± 1.77. There was statistically insignificant difference between the period of nonunion bone per months and fracture bone criteria of studied patients P>0.05. Also, there is statistically insignificant difference between lower extremities function score percent after implant procedure and fracture bone criteria of studied patients P > 0.05.

Conclusion

Augmentation plating is an excellent solution for the management of nonunited nailed long bones fractures with maintaining the nail in situ, especially with instability at nonunion site and comminution or gap nonunion.
Comparison of Outcomes following Vaginal Natural Orifice Transluminal Endoscopic Surgery and Laparoendoscopic Single-site Surgery in Benign Hysterectomy: A Systematic Review and Meta-analysis
Authors: Sarkar Avir , Sivaranjani P. , Zangmo Rinchen , Roy Kallol Kumar , Ghotra Maninder Kaur , Seelam Radha Rani , Pandey Shivam
Published: September 2023

Gradually increasing interest in laparoscopic surgeries has led to the advent of various lesser invasive techniques in the form of vaginal natural orifice transluminal endoscopic surgery (vNOTES) and laparoendoscopic single-site (LESS) surgery. Very few studies have analyzed the advantages and disadvantages of vNOTES over LESS surgeries in hysterectomy. After a comprehensive search, full texts of relevant manuscripts were obtained to assess eligibility for recruitment. A comprehensive meta-analysis was subsequently performed to compare the outcomes of vNOTES and LESS in hysterectomy, and forest plots were constructed. Four articles were rendered for review (three retrospective cohort studies and one randomized controlled trial). Three studies showed lesser postoperative pain in vNOTES compared to LESS. In one study, postoperative vaginal pain was higher in vNOTES due to additional suture between uterine artery and vaginal wall. The meta-analysis concluded that vNOTES could be better alternative to LESS hysterectomies. However, further large multicentric randomized trials are required for the standardization of the surgical method.
Assessment of tissue level of interleukin-9 in psoriasis and vitiligo
Authors: Mahmoud Sara B. , Salem Nesma A.M. , Shaker Olfat G. , Fahim Aya M.
Published: September 2023

Background

Psoriasis is a chronic, inflammatory, T-cell-mediated autoimmune disease. Vitiligo is an acquired depigmentary disease that occurs due to the loss of functional melanocytes from the epidermis. Interleukin (IL)-9 is a T cell-derived cytokine that was initially designated as a T helper2 cytokine. There is a link between the expression and action of IL-9 and pro-inflammatory cytokines tumor necrosis factor, IL-1, IL-17, and interferon-γ, suggesting that IL-9 is associated with the pathogenesis of autoimmune diseases.

Objective

To evaluate the tissue levels of IL-9 in patients with psoriasis and vitiligo in comparison with controls, to assess the possible role of IL-9 in the pathogenesis of these diseases.

Patients and methods

This case–control study included 30 patients with psoriasis, 30 patients with vitiligo, and 30 age-matched and sex-matched healthy controls. A skin biopsy was taken from all participants for evaluation of tissue IL-9 levels by enzyme-linked immunosorbent assay.

Results

Tissue IL-9 was significantly higher in patients with psoriasis (28.65±18.456) and patients with vitiligo (51.056±41.536) than controls (P=0.013 and P<0.001, respectively). In addition, it was significantly higher in patients with vitiligo than in patients with psoriasis (P=0.004).

Conclusion

This study suggests a possible role for IL-9 in the pathogenesis of psoriasis and vitiligo by documenting significantly higher tissue levels in patients than in controls.

Authors: Fathi Haitham B. , Al Mallah Mohammed N. , Al Chalabi Qasim S.
Published: September 2023

Background

Trichoscopy is an important tool in detecting alopecia areata activity.

Objective

To determine the relation of the trichoscopic markers with alopecia areata activity. To demonstrate its discriminative capabilities in classifying alopecia areata activity.

Patients and methods

One hundred and thirty-seven patients (86 males and 51 females) with alopecia areata underwent dermoscopic assessment of bald patches. Hair-pulling test was used to assess disease activity. A 2×2 table of alopecia areata activity and trichoscopic marker was used to estimate sensitivity, specificity, accuracy, predictive value, and likelihood ratio.

Results

Trichoscopic markers commonly seen in alopecia areata were short vellus hairs (65.7%), broken hairs (56.9%), exclamation mark hairs (46.7%), and black dots (42.3%). According to disease activity, exclamation mark hairs (91.9%) and broken hairs (87.1%) were the most common markers in active disease while yellow dots (72.3%) and short vellus hairs (69.3%) were in stable disease. Exclamation mark hairs (91.9% vs. 9.3%), broken hairs (87.1% vs. 38.7%), black dots (53.2% vs. 33.3%), and triangular hairs (21.0% vs. 8.0%) were significantly higher in active compared with stable alopecia areata. The discriminative capability index reveals that exclamation mark hairs (91.9%) and broken hairs (87.1%) were the most sensitive signs. Triangular hairs (92.0%), and exclamation mark hairs (90.7%) were the most specific markers. Exclamation mark hairs and broken hairs were the most reliable markers (91.2% and 72.9%, respectively). The presence of exclamation mark hairs, triangular hairs, and broken hairs in bald patches raises the likelihood ratio of activity by 9.88, 2.65, and 2.45 times.

Conclusion

Exclamation mark hairs are the most important reliable marker of disease activity. Broken hairs, triangular hairs, and black dots found in bald patches increase the chance of disease activity. Other trichoscopic markers(yellow dots, pigtail hairs, short vellus hairs, and upright regrowing hairs) were useless signs in determining disease activity.
Skin reactions to COVID-19 vaccination among Egyptians in three governorates
Authors: Alkady Osama H. , Abdelhameed Sara Y. , Rezk Shymaa M.
Published: September 2023

Background

In the first 6 months of the pandemic, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused more than a million deaths. Vaccines from several manufacturers, such as Pfizer-BioNTeck, AstraZeneca’s Vaxzevria, and Sinopharm, have been used in an effort to contain the pandemic.

Objective

To evaluate the skin reactions that occurred after receiving multiple types of coronavirus disease-19 (COVID-19) vaccinations among Egyptians in three governorates.

Patients and methods

This clinical cohort study was conducted on 1000 individuals receiving COVID vaccines. The registry’s vaccination module gathered data on vaccine dosage dates, cutaneous reaction(s), reaction timing, and duration. There were four categories of adverse responses to vaccines: systemic, local acute site reactions, delayed local skin reactions, and generalized cutaneous side effects.

Results

Of all individuals, 53.1% had previously contracted Covid-19. 76.3% of the study patients experienced systemic side effects. 91.4% of patients had an ‘injection site’ acute local cutaneous side effect. The Johnson and Johnson vaccination was associated with the highest systemic and local cutaneous side effects incidence, whereas the Sinopharm vaccine was linked to the lowest incidence. 10.2% of individuals experienced delayed cutaneous reactions, with the AstraZeneca vaccine having the greatest incidence and the Pfizer vaccine having the lowest.

Conclusion

Acute cutaneous side effect differs from one vaccine to another. Johnson and Johnson was associated more with bruising and redness, AstraZeneca was more associated with itching, and Pfizer was linked to increased discomfort and tenderness at the injection site. The AstraZeneca vaccination showed the highest prevalence of delayed cutaneous side effects.

Published: September 2023

OBJECTIVES:

To assess the oropharyngeal airway in Iranian female young adults with different skeletal patterns using cone-beam computed tomography (CBCT).

MATERIALS AND METHODS:

This descriptive, cross-sectional study evaluated 105 CBCT scans of female patients between 18 and 35 years retrieved from the archives of a radiology clinic. The images were evaluated in axial, sagittal, and frontal sections. In the axial plane, the maximum and minimum cross-sectional area (CSA) of the airways at the oropharynx, minimum width (anteroposteriorly), and minimum depth (laterally) were measured using Mimics Medical software. The oropharyngeal volume was measured by NemoFAB software. The values were compared among the groups with different sagittal, vertical, and transverse patterns. The correlation of indices with airway measurements was analyzed using Monte Carlo Chi-square and Pearson's correlation coefficient.

RESULTS:

No significant difference was noted in oropharyngeal airway dimensions and volume among cases with different skeletal sagittal, vertical, and transverse patterns (P > 0.05) except for class III patients with normal transverse pattern in whom maximum CSA in low-angle group was larger than that in normal-angle group (P < 0.05) and class I normal-angle patients in whom maximum CSA in transverse normal group was smaller than that in constriction group (P < 0.05).

CONCLUSIONS:

Oropharyngeal dimensions were not significantly different in Iranian female young adults with different skeletal patterns.

Authors: Omidkhoda Maryam , Eslami Neda , Mazloum Maryam , Entezari Mostafa
Published: September 2023

AIMS:

This study aimed to evaluate the bond strength of light- and chemical-cure adhesive systems over six months.

MATERIALS AND METHODS:

A total of 144 sound human maxillary first and second premolars were randomly divided into six groups according to the adhesive type (i.e., Transbond XT and Unite) and evaluation time. The groups were T0 (24-h group without thermocycling), T1 (24-h group with thermocycling), T2 (1-month group), T3 (2-month group), T4 (4-month group), and T5 (6-month group). The bond strength was then measured and the data were analyzed by SPSS software (version 23) through the independent t-test and one-way ANOVA. A P value less than 0.05 was considered statistically significant.

RESULTS:

The results of this study showed that shear bond strength of chemical-cure orthodontic adhesive (Unite, 15.37 MPa) at all-time points was significantly 1.37 times higher than that of the Transbond XT light-cure adhesive (11.15 MPa). Moreover, shear bond strength of self-cure adhesive (Unite) 1 month after debonding showed a significant difference with the 24-h group without thermocycling (P = 0.002), 24-h group with thermocycling (P = 0.008), and 6-month group (P = 0.016). The highest shear bond strength in both adhesives was observed at one month. Furthermore, the shear bond strength of Transbond XT light-cure adhesive one month after debonding showed a significant difference with the 24-h group without thermocycling (P = 0.000) and 24-h group with thermocycling (P = 0.000), as well as with the 2-month (P = 0.008), 4-month (P = 0.000), and 6-month groups (P = 0.016).

CONCLUSION:

Unite self-cure adhesive compared to Transbond XT light-cure adhesive has higher bond strength and is recommended for rebonding brackets in patients with multiple rebonds.
