Published: December 2023

Os impactos das inundações nas áreas urbanas geram diversos desafios que afetam os setores sociais, econômicos e sanitários, de maneira que é imprescindível criar cidades mais resilientes e sustentáveis. O Sistema de Drenagem Urbana Sustentável (SUDS) é uma abordagem integrada de manejo sustentável das águas pluviais correlacionada com o planejamento do espaço urbano agregada à visão tradicional do projeto de drenagem, que visa restabelecer os padrões hídricos do momento pré-urbanização. Este artigo tem como objetivo investigar as condicionantes urbanas e físicas de projetos que insiram Sistemas de Drenagem Urbana Sustentável (SUDS) em tecidos urbanos consolidados. A pesquisa foi feita por meio do levantamento de casos de estudo nacionais e internacionais e da sistematização dos dados em formatos de fichas e tabelas. Os resultados obtidos indicam que é viável a implementação de SUDS em tecidos urbanos consolidados.
Developing Critical Thinking: A Comparison of Three Disciplinary Approaches
Authors: Солодихина Мария , Солодихина Анна
Published: December 2023

Critical thinking is considered one of the most important results of university education. However, approaches to its development are controversial: there is very conflicting empirical data on the effectiveness of different approaches to the development of critical thinking.

Comparing approaches is difficult because different studies differ in the sets of critical thinking skills diagnosed, the learning conditions and the disciplines in which these approaches are implemented. Therefore, to carry out a comparative study of the effectiveness of infusion, immersion and mixed approaches to the development of critical thinking, a single discipline was chosen - “Concepts of modern natural science”, the differences between the approaches were formulated, which determined the general and different conditions for their implementation, a local definition of critical thinking for natural science was created, based on which identified a single set of diagnosable skills and developed a tool for their assessment. The study, covering 2019-2022, involved 619 students of the Faculty of Philology of RUDN University.

The mixed approach turned out to be optimal; it statistically significantly improved all groups of critical thinking skills. The infusion approach is less effective in developing decision-making skills and formulating inferences, but in other respects is not inferior to the mixed approach. The immersion approach is the least effective and primarily affects the group of information comprehension skills. The duration of the formation of critical thinking skills has a significant impact on the results: an impact spread  over two semesters is more effective than one compressed into one semester. The difference in results between first  and second year students may be explained by the cumulative nature of cognitive growth: learning has a delayed effect and there are epistemological crises in the perception of knowledge.

Published: December 2023

Influenza-like illness (ILI) accounts for 500,000 fatalities worldwide yearly. Environmental factors contribute to spread of respiratory infections. This study describes the epidemiological trends of ILI in Cheras, Kuala Lumpur, Malaysia and seeks scientific evidence on ILI activity and environmental factors. Cheras Health District collected ILI surveillance data and the nearest weather station which provided environmental data on mean temperature, humidity, wind speed, cumulative rainfall, particulate matter (PM)10 and PM2.5 levels. A total of 51,245 ILI cases were reported from 1st December 2021 to 30th April 2023. The non-linear relationship between ILI incidence and environmental variables was modelled using the Generalised Additive Model (GAM). The lag time for mean temperature, mean humidity, cumulative rainfall, mean wind speed, PM 10 level, and PM 2.5 level was 2, 3, 3, 3, 0, and 3 days, respectively. The model with the optimal lag better describes ILI case variance (R2=0.5, explained deviance=58%) than the model without lag selection (R2=0.5, explained deviance=57.2%). The Lag Model indicates a significant p-value for PM10 but no significant concurvity between predictor variables. Thus, the final model (R2=0.5, explained deviance=59.2%) has k=15. Higher rainfall, relative humidity, colder temperature, and decreased wind speed increased ILI incidence. PM2.5 and PM10 also contributes to ILI.

Authors: Acar Çevik Ulviye , Ercetin Tugba
Published: December 2023

Thiazole rings are one of the most frequently used heterocyclic moieties and are found in a wide variety of biologically active chemicals. In this research project, we report the synthesis and biological activities of some new thiazole derivatives (2a-2c) as potent anti-Alzheimer’s agents. These final compounds’ structures were characterized by spectral (1H NMR, 13C NMR, and MS spectra) analyses. The highest inhibitory activity against AChE was demonstrated by compound 2c (23.73 ± 0.018 %) with chloro substitution at the meta and para positions of the phenyl ring, while the highest inhibitory activity against BuChE was produced by compound 2a (28.87± 0.003 %) with cyano substitution at the f position of the phenyl ring. Ferrous ion-chelating and DPPH techniques were also used to assess the compounds' antioxidant properties. Compound 2a showed antioxidant effect according to the DPPH method with an IC50 value of 27.18 ± 0.009 µM.

Authors: Yiğit Fatih , Tarkan Nurettin , Akdeniz Mehmet , Erek Figen , Aydın Işıl
Published: December 2023

An easy and economical spectrophotometric method has been developed for the determination of atorvastatin from tablet formulation. This method is based on the formation of a blue-colored charge transfer complex of Atorvastatin with quinalizarin in methanol medium. The blue colored complex gives maximum absorbance at 573 nm. In order to develop the quantitative analysis method of atorvastatin, several parameters such as the type of solvent, the effect of reagent concentration, and the reaction time and temperature on absorbance of complex were investigated. It was determined that the optimum Quinz solution (0.5x10-³ M) was 3mL and the optimum temperature of the reaction was room temperature. Beer’s law range of proposed method is found 10-100 µg.mL-1. LOD and LOQ of the proposed method were found as 1.49 µg.mL-1 and 4.98 µg.mL-1, respectively. As a result, this proposed method can be used in the quantitative analysis of atorvastatin in tablet formulations
Development of Image Processing Based Line Tracking Systems for Automated Guided Vehicles with ANFIS and Fuzzy Logic
Authors: Yüksek Ahmet , Elik Ahmet Utku
Published: December 2023

Automated Guided Vehicles (AGVs) are robotic vehicles with the ability to move using mapping and navigation technologies to perform tasks assigned to them, guided by guides. Using sensor data such as laser scanners, cameras, magnetic stripes or colored stripes, they can sense their environment and move safely according to defined routes. The basic requirement of motion planning is to follow the path and route with minimum error even under different environmental factors. The key factor here is the most successful detection of the guiding structure of a system moving on its route. The proposed system is to equip a mechanical system that can produce very fast outputs and autonomous motion as a result of combining different algorithms with different hardware structures. In the line detection process, the wide perspective image from the camera is designed to be gradually reduced and converted into image information that is more concise but representative of the problem in a narrower perspective. In this way, the desired data can be extracted with faster processing over less information. In this study, the image information is divided into two parts and planned as two different sensors. The fact that the line information was taken from two different regions of the image at a certain distance enabled the detection of not only the presence of the line but also the flow direction. With the fuzzy system, the performance of the system was increased by generating PWM values on two different hardware structures, loading image capture, image processing processes and driving the motors. In order to determine the membership function parameters of the fuzzy system for each input, the ANFIS approach was used on the data set modeling the system. The outputs produced by the ANFIS model were combined into a single fuzzy system with two outputs from the system rules framework and the system was completed. The success of the algorithms was ensured by partitioning the task distribution in the hardware structure. With its structure and success in adapting different technologies together, a system that can be recommended for similar problems has been developed.
Twenty years of clients for religious architectures
Authors: Daprà Francesca , De Lucia Giulia
Published: December 2023

The contribution proposes a reflection on the relationship between the client, the architect and the various actors involved in the planning, design and construction of new churches, focusing on the Italian context in the last twenty years, and asking who can be considered the actual client for religious buildings. The selected time frame underlines a season characterised by different experimentation approaches for architectural competitions promoted, facilitated or supported by the Italian Episcopal Conference (CEI), starting from the experience of the Pilot Projects, passing through the Diocesan Paths, up to the most recent Participatory Processes, aimed at reducing the gap between Church client, user’s requests, and architectural projects. Such processes involve a large panel of actors, including the National and Diocesan bodies, local interlocutors, and the design teams, made up of various professionals. The study aims to investigate such recent procedures, to provide an analytical look at the maturing of the processes and to the identification of the collective client.
Gio Ponti y el Ospedale Maggiore de Milán, su cliente para la iglesia de Santa María Anunciata (1963-66) en el nuevo hospital milanés de San Carlos Borromeo
Authors: Crippa Maria Antonietta
Published: December 2023

Gio Ponti (1891-1979) abordó el proyecto de las iglesias cuando ya estaba en plena madurez. En su libro Amate l’architettura formulò dos ideas fundamentales para comprender la iglesia del nuevo hospital San Carlos Borromeo de Milán (1963-66). Creía que la antigua relación individual cliente-arquitecto había sido reemplazada por la social y más íntima arquitectura-función. Además, el proyecto de la iglesia no era una cuestión de arquitectura sino de religión.Una institución originaria del siglo XV —el Ospedale Maggiore (OM)— fue el cliente de Ponti, a quien se le encargó el proyecto de la iglesia y la inspección formal del exterior de todo el complejo hospitalario. Para la ejecución de obras litúrgicas y de devoción, Ponti involucró al padre Costantino Ruggeri (Pavia) y a la Escuela Beato Angélico (Milàn). Varios archivos nos permiten captar la dinámica que se produjo entre el arquitecto a cargo y el cliente.
The collaboration between client and architects on the construction of the church of Our Lady of Lourdes in Zagreb, Croatia
Authors: Sokol-Gojnik Zorana , Gojnik Igor , Crncevic Ante
Published: December 2023

This paper intends to enlighten the relationship between the architect and the client on the example of the construction of the church of Our Lady of Lourdes in Zagreb whose construction started in 1934 and today is almost finished. The project is a result of continuous cooperation between the architects Zorana Sokol-Gojnik and Igor Gojnik and the representative of the Franciscan Province, liturgist Ante Crncevic, who was in charge of the liturgical program, and Ivan Maletic, who was in charge of organizing the construction and financing.In this project, every architectural gesture and every place in the space has been carefully considered in an open and confidential dialogue between the architect and the liturgical theologian, in real mutual trust, humility, and teachability. The role of the architect is that of a conductor or director who must constantly keep the entire space under control and bring the parts into harmonious relationships.
An utopia made true
Authors: Leto Francesca , Comiati Gaetano Adolfo
Published: December 2023

The diocese of Vicenza, at the turn of the 1950s and 1960s, in close relation to social and ecclesiastical events, saw the utopia of an enlightened patronage designing together with architects two parish communities understood as a village come true. In biblical and liturgical rootedness, attentive listening and courageous response to the changes in the city, the faithful, guided by the authority of Fr Gianfranco Sacchiero at Villaggio del Sole (Vicenza) and Fr Nilo Rigotto at Villaggio Giardino (Arzignano), opened a fruitful dialogue with the Designers entrusted with the task of constructing not only a building of worship but a renewed, and in many ways unprecedented, experience of Church. The analysis of written documentary sources, architectural sources and testimonies will show the inadequacy of an authorial interpretative paradigm (awarding the merit of the architectural outcome to the architect/master alone) and the need to borrow concepts such as nascent state and charisma from the social sciences and psychology.
Exploración e identificación de sentidos en la producción de un territorio: relevamiento de necesidades, problemas y modos de respuesta en el primer nivel de atención de la Ciudad de Buenos Aires
Authors: Cortez-Fernandez Maria Guadalupe , Cammarota Karina
Published: December 2023

El acercamiento a un territorio implica interrogar el interjuego del espacio burocráticamente delimitado, las prácticas sostenidas por las instituciones que allí se desarrollan y las vivencias asociadas a los modos de vida de quienes lo habitan. Con el objetivo de analizar las percepciones y prácticas en salud de las instituciones del área de responsabilidad del CeSAC, se realizó un relevamiento cualitativo, de tipo exploratorio descriptivo, con muestreo no probabilístico por conveniencia. En los resultados de esta investigación, el territorio aparece como un espacio múltiple, siendo la noción de barrio una unidad territorial en la impronta identitaria de los “vecinos”. Se identifican grupos sociales con modos de vida colectivos caracterizados por el entrecruzamiento de relaciones de clase, de género e intergeneracionales. En los barrios, en tanto contexto de vida, las instituciones funcionan como mediaciones sociopolíticas a través de prácticas que constituyen formas de producción de cuidado colectivo. Estas formas de cuidado amplían los sentidos de la idea de salud, diferenciándose de las conceptualizaciones médico-biologicistas. Se ubican prácticas de participación ciudadana y de participación comunitaria, relacionadas con los modos de vida, en las que se vehiculizan intereses, posibilidades y potencialidades.
Estudio sobre la efectividad de la publicidad en términos de recordación de la marca a partir de los anuncios intrusivos en la red social YouTube
Authors: Samudio-Barrios Silverio
Published: December 2023

El propósito de este estudio es determinar la efectividad de la publicidad en términos de recordación de la marca mediante el empleo de la publicidad intrusiva en la red social YouTube. La investigación es de carácter exploratorio y descriptivo que se sitúa dentro del paradigma interpretativo. Se seleccionaron a los estudiantes de marketing y publicidad del primer semestre de 2023 bajo la figura de un muestreo no probabilístico por conveniencia. De la muestra analizada participaron 48 estudiantes que pertenecen a una misma universidad. Los resultados demuestran que la mayoría de los mensajes publicitarios pasan desapercibidos ante los ojos del público online y, en lugar de generar atención, interés o recordación, lo que producen en la audiencia es molestia y experiencia negativa. Ante esta situación, se sugiere el marketing de atracción o de contenido para que el público online sea partícipe en los quehaceres de las marcas en vez de interrumpirlo, ofreciéndole un valor agregado y un mensaje mucho más personalizado.
Registro datado de acontecimientos y procesos como archivo del desarrollo de la sociología en Paraguay. Parte II: de los 80’ a la contemporaneidad
Authors: Caballero Merlo Javier Numan
Published: December 2023

El objetivo general es continuar completando el puzzle que componen algunos de los nuevos cuadrantes del campo de la sociología local que la prefiguran dinámicamente sumando a lo ya expuesto en la Parte I: de 1900 a la década de los 80’. Como materiales, se consideran acontecimientos datados por una cronología y referencias registradas documentalmente; y el cómo se fueron generando en la dinámica histórica cambios en su institucionalidad, actividades, espacios editoriales, asociaciones profesionales, de cooperación, formación local e internacional, acceso y financiamiento a la investigación. El método es cualitativo, las técnicas combinan las entrevistas, listas de cotejo documental, análisis de datos secundarios y de contenido que buscan la triangulación para la saturación cualitativa que posibilite la labor de registro y archivo. Entre los principales resultados y conclusiones se evidencia que, en el período abordado, a finales de los 80’ hasta la época ya en un contexto de apertura democrática se fundarán nuevos centros privados. Asimismo, con el nuevo milenio, y, desde el espacio universitario público, se desarrollarán los primeros cursos de posgrado con titulaciones específicas o con énfasis en sociología. Sumándose la tercera experiencia de una nueva licenciatura en sociología en el país, pero esta, desde una universidad pública (FACSO); junto con su primera oferta de un programa de posgrado en ciencias sociales, y publicación de sus propios cuadernos. Aunque también se perciben retrocesos como el caso del cierre del Programa de Maestría en Sociología por parte de la UNA (2017). Asimismo, otra institución pública ofrece nuevas alternativas de formación de recursos humanos en el exterior (BECAL), generándose simultáneamente otras redes de cooperación locales interinstitucionales, regionales (AUGM) o internacionales (CLACSO); así como nuevas sociedades científicas, asociaciones profesionales (SPS, APS) y la participación en la actividad investigativa de manera sostenida, gradual y creciente, con el financiamiento local a partir de programas como PROCIENCIA y PRONII del CONACYT.
Análisis cienciométrico de la produción científica sobre la educación inclusiva en educación primaria (2000-2020)
Authors: Hernández Valverde Francisco José , Vallejo-Ruiz Mónica
Published: December 2023

El presente artículo analiza diacrónicamente la producción científica española relativa al ámbito de la educación inclusiva en la etapa de Educación Primaria indexada en la base de datos ÍnDICEs-CSIC, durante el periodo 2000-2020. Dicho análisis se realiza a un doble nivel: cienciométrico y conceptual. El primer análisis aporta evidencias sobre los siguientes indicadores cienciométricos: producción diacrónica, revistas con mayor productividad científica, autores más productivos, filiación institucional, materias y temática. El análisis conceptual, a través del programa informático Atlas.ti (versión 22), ha permitido identificar los tópicos de investigación, y su relación entre ellos, más relevantes en el campo de la educación inclusiva en esta etapa educativa. Como resultados generales del estudio se pone de manifiesto, entre otros aspectos, la conexión de la educación inclusiva con múltiples áreas o ámbitos de la educación, así como la consolidación científica -tal y como planteaba Price (1963), de este ámbito científico. Asimismo, se evidencia la falta de apoyo y respaldo institucional a la gestión de esta base de datos española (y de acceso libre) que permite realizar estudios de esta índole.

Indwelling ureteral stenting negatively impacts sexual function transiently after endourological procedure among adult male and female patients: a prospective cohort study
Authors: Kangsaputra Ferdy Bangun , Budiyono Nur , Brodjonegoro Sakti Ronggowardhana
Published: December 2023

BackgroundUreteral stents, which are widely used after endourological procedures, cause adverse effects. However, its potential impact on sexual function remains unclear in patients undergoing ureteral stenting. This study aimed to investigate sexual function in adult male and female patients undergoing endourological procedures involving ureteral stent placement.
MethodsWe conducted a prospective cohort study in a double tertiary care hospital setting with 103 selected patients (53 male and 50 female). We used a self-administered questionnaire-based survey, namely the Indonesian version of the 5-item International Index of Erectile Function (IIEF-5) for male patients and the Indonesian Female Sexual Function Index (Indonesian FSFI) for female patients at three different times (pre-stenting, four weeks after stenting, and four weeks after stent removal). A paired t-test or Wilcoxon test was used for data analysis.
ResultsIn the male group, significant changes were noted in the four IIEF-5 domains and overall IIEF-5 scores at pre-stenting and four weeks after stenting (p =0.000). The female group showed significant differences for all FSFI domains and overall FSFI scores at pre-stenting and four weeks after stenting (p=0.000). Most patients in both groups recovered sexual function four weeks after stent removal, as indicated by insignificant differences in the overall IIEF-5 and FSFI scores at pre-stenting and four weeks after stent removal.
ConclusionUreteral stenting led to significant but transient sexual dysfunction in both groups at four weeks after stenting. In this regard, male and female patients need to receive counselling and attention, that they may experience temporal sexual dysfunction at least for 4 weeks.

Deep learning is crucial for advancing artificial intelligence in robotics. Deep learning enables autonomous robots to perceive and control their environment. Federated learning allows distributed robots to train models while maintaining privacy. This paper focuses on using FL to overcome vision-based obstacles in mobile robotic navigation. We evaluate FL’s performance in both simulated and real-world environments. Our research compares FL’s multiple image classifiers to cloud-based central learning using existing data. We also implement a continuous learning system on mobile bots with autonomous data generation. Training models in simulation and reality improves accuracy and enables continuous model updates.

Глубокое обучение имеет решающее значение для развития искусственного интеллекта в робототехнике. Оно позволяет автономным роботам воспринимать окружающую среду и управлять ею.

Teacher Education. A Black Student-Teacher’s Narrative About Black Identity
Authors: Ubaque-Casallas Diego F. , López-Forero Geraldine , Bohórquez González Laura Catherin
Published: December 2023

Student-teachers’ Black identities have barely been documented in initial teacher education. Although some studies have focused on their cultural experiences, their identities are still unexplored to understand teacher education. This is why this study adopts a narrative perspective to address, through life story interviews, the identity formation and experience of a Black woman and student-teacher at a public university in Bogotá, Colombia. By dwelling on her experience, this study reflects upon how, although Black students deny their identities when learning a foreign language and becoming teachers, their personal and historical backgrounds work to position themselves politically and ideologically. Race and body become intersectional categories to comprehend their processes of resistance. This exploration also discusses how discursive representations have a stake in the constitution of Black identities in teacher education.
Nickel plating on wood and wood composite surfaces: Characterization of surface durability
Authors: KELLECİ Orhan , KÖKSAL Süheyla Esin , ULUTEPE Erol
Published: December 2023

In this study, the performance of nickel plating on wooden surfaces was investigated. Black pine (BP), medium density fiber board (MDF) and particle board (PB) were used for the wooden samples. After the sample surfaces were sanded with 200, 500 and 1000 grit sandpaper and varnished with polyurethane varnish (150 g/m2), they were nickel plated using a spray gun and compressed air. After drying the samples at room temperature for 72 h, scratch analyses were performed according to TS EN 15186 (2012) and TS EN ISO 2409 (2020) and abrasion analyses were performed according to TS EN 13329 +A. The staining resistance of the samples was determined according to the DIN 53799 standard. According to the results, surface strength of the MDF samples was lower than those of PB and BP. The scratch analysis results for the black nickel coating were lower than those for TS EN 15186 (2012). However, it was higher according to TS EN ISO 2409 (2020) scratch analysis. In terms of stain resistance, all samples were found to be resistant to water, soap, tea, and acetone stains, except for coffee stains. Upon visual examination, a slight coffee stain was observed on the sample surfaces. As a result, in the light of surface strength analysis, it was concluded that the surfaces of wooden boards are not suitable for nickel plating.

Ancak bu kontrol esnekliği, ortam şartlarındaki her değişkenle ilgili dikkati de beraberinde getirmektedir. Bu çalışmada bu değişkenlerden hava hareket hızının tespiti, kurutmaya etkisi ve kurutmanın iyileştirilmesi için hava hareketini yönlendirmesi için yerleştirilen boşluk kapatma levhasının (panel) etkisi tespit edilmeye çalışılmıştır. Bu kapsamda yaklaşık 10 m3 meşe kerestesi, kondenzasyonlu bir kurutma fırınında yarı-otomatik kontrol sistemi ile kurutulmuştur. Kurutma sonrasında iki hol boşluğu referans alınarak kerestelerin rutubet içerikleri ve tüm fanlar açıkken toplam 42 bölgeden anemometre ile istif katları arasındaki hava hareket hızları ölçülmüştür. Elde edilen sonuçlar, panel konulmadan ideal kurutma şartlarından uzaklaşıldığı için, standartlardaki rutubet dağılımı kriterine göre düşük kalitede veya standart dışı kurutma yapıldığı belirlenmiştir. Panel ile yapılan müdahale ile hava hareket profilinin iyileştiği ve havanın istif katları arasında daha homojen bir şekilde dağıldığı tespit edilmiştir. Panel konulmasına karşın sadece istif üst katlarında, literatürde de belirtilen bir sorun nedeniyle, hava hareket hızında yeterince iyileşme sağlanamamıştır. Bununla birlikte fırında ısıtma ve hava hareketi için sadece elektrik kullanıldığı için, farkındalık oluşturması açısından kurutma sırasında tüketilen elektrik enerjisi de ölçülmüş ve dış ortam sıcaklığıyla ilişkilendirilmiştir. Sonuçlar, tüketim verilerinin hava şartları değişimine bağlı olarak değişmediği tespit edilmiştir. Bu duruma fırın yalıtım performansının ve/veya fırının kapalı bir mekânda yer almasının etkili olduğu düşünülmektedir. Kurutmanın ikinci yarısında artan ortalama enerji tüketim miktarının, kurutma programında istenen daha şiddetli şartlar nedeniyle, kondenzasyon cihazının daha fazla devreye girmesinden kaynaklanmış olabileceği sonucuna varılmıştır.

Cultivating religiosity among students in schools is a crucial initiative that should be implemented. The aim of the research project was to evaluate the impact of school climate on students' development of religiosity. The research methodology used mixed-method explanatory models to evaluate theories on the influence of school climate on religiosity and to explore the strategies that teachers use to develop students' religiosity within schools. Quantitative data was collected from 482 students at junior and senior schools, and qualitative data was gathered from six randomly selected teachers. Quantitative data was collected using school climate and religiosity scales. Descriptive and regression analyses were used to analyze the quantitative data, while thematic analysis was used for the qualitative data. The regression analysis results showed a value of R = 0.338, R2 = 0.114, p .005, indicating a positive impact of school climate on students' religiosity. Teachers employ six approaches to achieve this goal: habituation, guidance, leading by example, attention to individual students' needs, creating a positive atmosphere, and providing educational sanctions. These results highlight the importance of improving teachers' expertise in promoting student religiosity. Experimental research could be an effective alternative for further advancing this type of study.

Published: December 2023

Background: Pyogenic flexor tenosynovitis is an aggressive closed-space infection, which affects the flexor tendon sheath of the hand with disabling sequelae. The purpose of this study is to describe the patient demographic characteristics and identify factors associated with amputation in pyogenic flexor tenosynovitis.
Methods: In this retrospective single-center study, included all adult patients who presented to the emergency department from 2015 to 2021 with PFT of the hand. Descriptive summary statistics were reported on patient demographics, presenting symptoms and clinical examination features, culture results, treatment strategies, and early complications. The factors influencing amputation were identified and analyzed.
Results: A total of 59 patients with PFT diagnosis were included. Most of the population was found to be immunosuppressed (34 patients). Moreover, the most common comorbidities were the combination of diabetes mellitus and systemic arterial hypertension. The third right finger was the most frequently affected region. Almost all patients were hospitalized, intravenous antibiotics, and at least one additional surgical intervention was required in 16 cases. Amputation of the infected finger occurred in 6 patients, associated with different factors: reintervention, age over forty, presence of diabetes mellitus and chronic arterial hypertension, penetrating trauma, and presence of Enterococcus faecalis in culture.
Conclusions: Rapid and aggressive treatment is required to prevent devastating complications such as amputation. Adequate identification of the disease and risk factors is critical for a successful result. E. faecalis represents the most common pathogen in this study, unlike the reported literature. Thus, broad-spectrum antibiotics and surgical intervention are required.

Authors: Uchintala Venkata Sai Sreenivas , Srinivasan Uma Sankar , Syed Tajuddin , Prabhu Eswar Gollahalli , Selvam Shaktivel
Published: December 2023

Background: Acute cholecystitis patients undergo laparoscopic cholecystectomy (LC) within 72 hours or 6 weeks to 12 weeks after onset is widely considered the optimal timings for LC. However, there has been no clear consensus about it. We aimed to determine safe technique of LC for acute cholecystitis within 72 hours or any time of presentation with no delay in surgery.
Methods: Medical records of 100 patients who underwent standard LC were reviewed retrospectively. Patients were divided into group 1, patients undergoing LC within 72 hours of onset; group 2, between 4 days to 14 days; group3, between 3 weeks to 6 weeks; group 4, more than 6 weeks.
Results: No significant differences existed between groups in conversion rate to open surgery, operation time, blood loss, or postoperative morbidity, and hospital stay. However, total hospital stays in groups 1 and 2 was significantly shorter than that in groups 3 and 4 (p<0.01). In addition, the total hospital stay in group 3 was also significantly shorter than that in group 4 (p<0.01).
Conclusions: Best timing of LC for acute cholecystitis may be within 72 hours, and there is no need to delay LC in patients presenting after 72 hours and with safe technique of dissecting at infundibulum retrieval of stones and cystic duct stump closure with catgut loop there is no significant difference observed retrospectively.

Published: December 2023

Background: Laparoscopic cholecystectomy (LC) is widely used for cholecystolithiasis. Abdominal ultrasonography (USG) is the investigation of choice for diagnosis of gall stone and often done before cholecystectomy. It also helps to predict possible complications during peri-operative period. Till now, there is no established definition of difficult LC.
Method: Patients diagnosed as cholecystolithiasis confirmed by USG were studied. Nine parameters of abdominal USG had been assessed. Each parameter was divided into two groups, group A and group B based on finding of USG. Total number of USG finding of each group was calculated. Each surgery was assessed and categorise as easy or difficult and co related with total number of USG finding of each group.
Results: For difficult LC-group B USG criteria ≥4 with group A USG criterion ≤5 having sensitivity 84.09%, specificity 80.43% and diagnostic accuracy 82.22%. For easy LC-group A USG criterion ≥6 with group B USG criteria ≤3 having sensitivity 80.43%, specificity 84.09% and diagnostic accuracy 82.22%. For easy LC, the mean post-operative stay was 1.57 days and for difficult LC, the mean post operative stay was 2.52 days.
Conclusions: Preoperative USG assessment is a good predictor of difficult LC. Thick-walled gall bladder (GB), presence of pericholecystic fluid collection, impacted stone at neck or proximal to neck of GB and contracted GB are good predictors of difficult LC. Gender is not an independent risk factor for difficult LC.

Published: December 2023

Gallstone ileus and Bouveret's syndrome are rare gallstone complications; therefore, their combination is even rarer. The delay of diagnosis is associated with high rates of morbidity and mortality. We reported a 65-year-old woman presented with a three-day history of epigastric and lower right abdominal pain, nausea, and vomiting. A radiopaque shadow was noted on an abdominal X-ray in both the right upper and lower quadrants. In addition to the cholecysto-duodenal fistula, the CT abdomen revealed a combined ileal gallstone ileus with small bowel dilatation and stone in the second portion of the duodenum (Bouveret's syndrome). Initial attempts to extract duodenal stones endoscopically were unsuccessful. Therefore, the patient underwent an exploratory laparotomy and removal of both ileal and duodenal stones. The patient had an uneventful postoperative course. Serious complications include obstruction of the gastric outlet or the small intestine due to gallstone ileus, Bouveret's syndrome, or both. Despite the high failure rate, endoscopic extraction of the stone alone or in combination with lithotripsy is the standard treatment for Bouveret's syndrome. Furthermore, surgical intervention is the standard treatment for gallstone ileus. Gallstone ileus and Bouveret's syndrome remain diagnostic and therapeutic challenges, which necessitate an immediate multidisciplinary approach to prevent substantial morbidity and mortality. Further reports or larger-scale studies are encouraged.

Published: December 2023

The Amyand hernia is a rare type of inguinal hernia where the appendix is located within the hernial sac. It is present in less than 1% of inguinal hernias and in 0.13% of cases, it is associated with complications including acute appendicitis and perforation. This case details an 81-year-old female with recurrent Amyand hernia with perforated appendicitis and a sessile serrated lesion. A literature review was conducted to identify existing cases of the Amyand hernia and neoplasm or recurrent inguinal hernia. Fifteen cases of neoplastic appendix within an Amyand hernia were identified in the literature. All cases found acute appendicitis, three of which were perforated. Histology varied from adenocarcinoma, goblet cell, carcinoid, fibroma, and mucinous cystadenoma. There were nine identified cases of Amyand hernia within a recurrent inguinal hernia. Seven of these cases had acute appendicitis, three of which were perforated, whilst one was gangrenous. All cases performed an appendicectomy, and various open techniques were used for hernia repair with or without mesh. The most interesting finding of the literature review was that Amyand hernia is rarely diagnosed pre-operatively, and that there was a high incidence of appendicitis when in the presence of a neoplastic appendix or a recurrent inguinal hernia. This paper highlights the first reported case of an Amyand hernia with a simultaneous neoplasm and recurrent inguinal hernia, which was managed using a laparoscopic approach without hernia repair.

Facial feminization surgery (FFS) is the sequential procedure for reshaping the face to appear more feminine. It is usually take on due to transsexual individuals who want transformation from men to women or for the females want to wish for more advanced feminize facial features. Multidisciplinary treatment planning team is the basic necessity for any patient who is seeking for FFS. Orthodontists possess the chief characteristic within the multidisciplinary team because patients may initially appear to the orthodontist for the concern of their jaw appearance. For that reason, orthodontists should have the detailed knowledge about FFS procedures, to authorize the best communication with the patient, thorough the assessment of the patient and further referral where there is the requirement. Present article reviews the commonly used FFS procedures, their implications, benefits as well as the risk factors of every procedure and highlights the orthodontist’s role.
