El valor de una identidad: la cultura del pueblo gitano a través del arte (1850-1950)
Authors: Martínez Bonilla Isabel
Published: May 2023

El presente artículo aborda la importancia de la identidad, en concreto, la cultura del pueblo gitano a través del arte. Para esta minoría, presente en España desde 1425, la identidad fue primordial, ya que durante siglos fueron perseguidos con el fin de eliminar cualquier elemento que formase parte de su idiosincrasia. Sin embargo, a pesar de todas las adversidades a las que se enfrentaron, lejos de olvidar todo aquello cuanto les definía, decidieron conservarlo. Este artículo, por tanto, tiene como finalidad analizar desde un punto de vista antropológico y artístico algunas de esas manifestaciones culturales que identifican a los gitanos y que para ellos resultan de gran relevancia, como es el caso de la música y danza ‒en concreto, el flamenco‒ la religión, el rito nupcial y la celebración de la muerte. Una rigurosa selección pictórica y fotográfica ayudará a responder las siguientes cuestiones:
En primer lugar, si los aspectos que constituyeron su patrimonio etnográfico han permanecido invariables a lo largo del tiempo, o bien, han sufrido alteraciones.
En segundo lugar, comprobar si los artistas que trataron tales temas construyeron un mito sobre dicha minoría, o por el contrario, supieron captar de manera objetiva su legado cultural.
El padrón como frontera: La utilización del registro municipal de habitantes como dispositivo de inclusión diferencial
Authors: Borràs-Batalla Marc , Oms-Graells Anna Maria
Published: May 2023

El presente artículo es un estudio sobre el uso excluyente que las ciudades del área metropolitana de Barcelona hacen del registro municipal de habitantes (padrón) para evitar que las personas inmigradas en situación de exclusión residencial adquieran la condición de residente. A partir de entrevistas a personas migradas, que por su vulnerabilidad residencial habían experimentado impedimentos para conseguir el padrón, este estudio muestra la naturaleza del circuito informal de empadronamiento que emerge de las prácticas burocráticas excluyentes y cuáles son las repercusiones directas para con las personas discriminadas. En este sentido, el estudio muestra que el padrón se erige como el principal incentivo para la movilidad residencial intra e interurbana de las personas inmigradas que entrevistamos. Este hallazgo es especialmente significativo porque contradice las afirmaciones que durante décadas han difundido tanto la Generalitat de Catalunya como algunas de las principales administraciones locales catalanas y principales partidos políticos, según las cuales, los impedimentos para el empadronamiento no suponen un desincentivo para la residencia efectiva en el municipio.

Authors: Kézai Petra Kinga , Gombos Szandra , Jakobi Ákos
Published: May 2023

A 21. században a jólét megteremtéséhez a kulturális és kreatív gazdaság a helyi és regionális szinten is hozzájárul. Jelen tanulmány a kulturális és kreatív gazdaság jelenét és jövőjét vizsgálja a Szigetközben. Célja feltárni a szűken értelmezett kulturális és kreatív ipar erejét és a benne rejlő eddig még feltáratlan potenciálokat a Szigetköz területén található 35 településen.
Elemzésünk elején szakirodalom által tárjuk fel a kulturális és kreatív gazdaság, illetve a hozzá tartozó iparágak (CCI) fogalmakat, majd statisztikai elemzések alapján határozzuk meg a Szigetközben a kulturális és kreatív gazdaság súlyát és jelentőségét 2015-2020 időszakban. A vizsgálat a Dun & Bradstreet Hungary Kft. céginformációs rendszer adatain alapul és kitér külön az egyéni vállalkozásokra és a gazdasági társaságokra.
Mivel a folyamathoz komplex módon közelítünk, ezért figyelembe vettük a helyi jellegzetességeket, és munkánk második részében interjúk (n=21) kerültek felhasználásra. Tanulmányunk a szigetközi kistáj mikroszintű CCI szektorát kívánja bemutatni a 2015–2020 időszakban, ahol a gazdasági társaságok száma folyamatosan csökken, az egyéni vállalkozók száma folyamatosan nő, de többségük tevékenysége kevésbé látható (és ezáltal kevésbé igénybe vehető) a szélesebb közönség számára. Rávilágít továbbá a Szigetköz kulturális és kreatív iparának problémáira és hiányosságaira, amelyek négy fő csoportba sorolhatóak: a kreatív gazdaság helyi meghatározottsága, a kereslet és kínálat „találkozási pontjai”, az együttműködések és kommunikáció, valamint a kreatív gazdaság működési és operatív kérdései. A tanulmány a szigetközi térség kulturális és kreatív iparának fejlesztésére tett ajánlásokkal zárul.

An Employment Contract with a Teacher: Actual Problems of Concluding Such Contracts and Content of Supporting Documents
Authors: Shonia G. V.
Published: May 2023

The pedagogical activity of a teacher at an educational organization is of a special social significance. The principles of continuity and professionalism of organization and conduct of the educational process have a significant impact on relations regulating conclusion, renewal and the content of an employment contract with a teacher. A turning point in law enforcement practice, as well as in the legislator’s approach to regulating the relations under consideration, took place when Resolution of the Constitutional Court of the Russian Federation No. 32‑P of 15.07.2022 was passed. A modern employment contract with a teacher is not limited to one document. The educational organization (an employer) should pay attention to the documents accompanying the employment contract with the teaching staff. Based on the analysis of current provisions of labor legislation and legislation protecting personal data, the doctrine, judicial and business practice, the author makes conclusions and recommendations regarding the solution of problems related to the conclusion, renewal and content of an employment contract with the teacher, as well as regarding the accompanying documents. The paper substantiates the composition and content of such documents, makes proposals regarding lawful processing of personal data of the teaching staff and reporting to Roskomnadzor.

Likelihood of Primary Surface Faulting: Updating of Empirical Regressions
Authors: Pizza Marco , Ferrario Maria Francesca , Thomas Frank , Tringali Giorgio , Livio Franz
Published: May 2023

Surface faulting is a common phenomenon for crustal earthquakes and is an important source of localized hazard to buildings and infrastructure. Nevertheless, not all earthquakes of a given magnitude generate surface faulting. To correctly assess the hazard posed by surface fault displacement, it is critical to use reliable regressions of the likelihood of surface faulting. Such regressions are derived from empirical data and the ones currently used in engineering practice are based on datasets acquired several years ago. The aim of this work is to update the regressions characterizing the likelihood of primary surface faulting (i.e., P(Slip|m)). We systematically analyze Mw≥5.5 earthquakes that occurred in 1992–2018, with hypocentral depths lower than 20 km and epicenter onshore. We obtain information on the occurrence or non-occurrence of primary surface faulting for 363 earthquakes (87 with primary surface faulting and 276 without). We derive empirical regressions of P(Slip|m) from the entire dataset as well as for normal, strike-slip, and reverse earthquakes, and discuss the potential sources of aleatory and epistemic uncertainty. A sensitivity analysis shows that the P(Slip|m) term has a significant impact on the hazard curve expressed as the annual frequency of exceeding a given displacement value. We argue that the regressions presented in this work can be incorporated in models for probabilistic fault displacement hazard assessment, ultimately providing a better evaluation of the hazard.
Representing earthquake intensity-magnitude relationship with a nonlinear function
Authors: Cavallini Fabio , Rebez Alessandro
Published: May 2023

A careful analysis of the concepts of earthquake intensity (I) and magnitude (M) shows that no straight line (obtained, for example, by fitting a catalog of observed {I, M} pairs) can adequately represent the intensity-magnitude relationship throughout the whole range of (theoretically) possible values. The remedy is straight-forward: fit the data (M versus I) with a nonlinear function (precisely, the inverse of a sigmoid curve) instead of a straight line.

This recipe has been applied to two data sets (from California and Italy) with satisfactory results, which are compared with those obtained from a sigmoid (I versus M) and from three alternative linear regression methods (I versus M, M versus I, and orthogonal regression line). It appears that this method works well not only for interpolation purposes but also for extrapolation; hence, it should be of interest to seismic engineering for exploring extreme, unprecedented scenarios.

Moreover, the abundance and statistical dispersion of middle-range observed data is an independent source of error as far as magnitudes corresponding to high-intensity events are to be estimated. This can be obviated by averaging, before fitting, the magnitude data that correspond to the same intensity. However, this procedure affects more the straight lines than the inverse sigmoid curve (M versus I), which shows great robustness.

Günümüz dünyasında yaşanan çevre felaketleri göz önüne alındığında, insanın çevrenin hassas dengeleriyle bağdaşmayan tek taraflı bir sömürü ilişkisi geliştirdiğini söylemek mümkündür. İnsanlığın yaşama alanına dair sorunlarının her geçen gün artarak devam etmesi, meselenin küresel boyutta bir sorun haline gelmesine ve disiplinlerarası bir boyut kazanmasına sebebiyet vermiştir. Bu sorunun çözümüne ilişkin farklı alanlarda yapılan tartışmalar sonucunda çevre sorunlarının çözümünde en etkili ve kalıcı çözüm yolunun eğitim olduğu kanaatine varılmıştır. Ülkemizde çevre bilincini oluşturmaya yönelik ilkokul, ortaokul ve lisede müstakil bir ders bulunmamakta, çevre eğitimi, fen bilimleri, sosyal bilgiler ve Din Kültürü ve Ahlak Bilgisi (DKAB) gibi farklı dersler içerisinde verilmektedir. DKAB derslerinde çevre konusu genellikle ilişkide olunan sosyal çevre bağlamında değerlendirilmiştir. Bu bağlamda, çalışmada 2018 sonrası DKAB öğretim programı, fiziksel çevre açısından ele alınmış ve öğretim programının verimliliğini artırma açısından önerilerde bulunulmuştur. Çalışmada, dinlerin çevreye olan bakış açısına değinilmiş, ayrıca “Örgün eğitim kurumlarında, diğer derslerin yanında DKAB öğretim programının çevre bilinci oluşumuna katkısı var mıdır?” sorusundan hareket edilerek programlar ünite, konu ve kavramlar açısından bütün olarak ele alınarak fiziksel çevrenin korunmasında din eğitiminin rolü araştırılmıştır. Doküman incelemesi ve içerik analizi yöntemlerinin kullanıldığı çalışma sonucunda DKAB öğretim programlarında fiziki çevre bilinci oluşturmaya yönelik konu ve kazanımlar olmakla birlikte, bunların yetersiz olduğu dolayısıyla mevcut öğretim programının bu haliyle öğrencilerde çevre bilinci oluşturmaya yönelik yeterli katkı sağlamayacağı sonucuna ulaşılmıştır.

Aluminum alloy 6061-T6 is a commonly used material in various industries, including automotive parts manufacturing. However, its machining process can be challenging due to the occurrence of build-up edge (BUE) at the cutting edges. To address this issue, this research employed trochoidal milling to machine aluminum alloy 6061-T6 specimens, utilizing a small step over and a suitable depth of cut. The engagement of the tool during the machining process generates fluctuating forces, which consequently leads to fluctuations in temperature. This phenomenon is not only observed in trochoidal milling but also in conventional machining methods. The results indicate that the calculated maximum temperature (350°C) is lower than the aluminum's melting point (652°C). Moreover, the experimental results show minimal BUE formation on the cutting edge and an improved milling process.

The multi-motor drives, the typical examples of which are continuous lines (CL) for tension processing of various materials are complex and coupled MIMO higher-order nonlinear systems, which parameters are difficult to identify. The article focuses on a method for the design of a non-parametric black-box fuzzy model of a continuous production line with emphasis on minimal knowledge on the modelled system. The proposed fuzzy model structure is based on the state space representation of the dynamic system in discrete form, which only requires a suitable set of information on its input/output relations. The properties of the proposed CL fuzzy model were verified by experimental measurements on a CL laboratory model. The obtained results have confirmed the rightness and effectiveness of the fuzzy model design method that can be applied not only in the field of industry technologies with CL but also in modeling and control of nonlinear dynamic systems.

This article shows an example of designing an induction motor model. Calculation of electrical parameters of induction motor in Ansys Electronic Suite - Maxwell RMxprt. The finite-element analysis of the CAD model was performed both in two-dimensional space using Ansys Electronic Suite software of Maxwell RMxprt subprogram and in three-dimensional space using Ansys Mechanical software. The natural frequency of the motor rotor is between 922 Hz and 1014.6 Hz, so these frequencies must be skipped when controlling a motor of this configuration. The obtained values of electric current, torque, and operating speed can be adjusted by changing the internal components of the winding, stator, and rotor design. All the studies can be modified and used to study induction motors with other parameters. In particular, the created project in Ansys software can be used to design an induction motor with its characteristics, optimal for the required tasks.

Although energy consumption is highly related to economic growth and development finance, a consensus on the direction of causality among them has not been reached. To this end, this study aims to investigate the causal effect of economic growth and development finance on energy consumption with a focus on middle-income countries over the period of 1994-2014. Our empirical highlights unidirectional causality running from economic growth to total energy consumption; unidirectional causality running from financial development to total energy consumption; unidirectional causality running from renewable energy consumption to financial development; and unidirectional causality running from non-renewable energy consumption to economic growth. Based on the empirical findings, the article proposes some innovative solutions for effective energy management in smart cities towards sustainable development, harmonizing economic development and energy consumption.

The focus of this paper is to compare the results of topological optimization (TO) of the rocker arm for following 3D printing out of AISI 316L stainless steel by the Selective Laser Melting (SLM) method. We used the Altair Inspire software to optimize the shape of the rocker arm. Two variants of optimization were created, first, a variant of optimization without the Shape Control function was carried out, which resulted in a complex mechanical component with an organic shape. This bionic design means more support for the SLM method of Additive Manufacturing (AM) and worse surface quality after their removal. Therefore, a second variant of optimization was produced with the application of the Shape Control function, which positively affects manufacturability and postprocessing. The use of shape control reduced the amount of supports to a minimum, helping to improve the surface finish.

A new ultra-high strength steel with a fully austenitic microstructure and twinning-induced plasticity (TWIP) effect has been developed. TWIP effect gives this steel a good combination of high strength of over 1000 MPa and ductility of over 35%. This new steel has a high chromium content, which increases its corrosion resistance. By combining cold rolling and annealing, the steel has achieved a very fine austenitic microstructure with an average grain diameter of 2.85 µm. This steel could be used for structural applications or components that need to withstand high levels of stress, deformation and corrosion environment.

This research article presents a comprehensive study on ceramic materials using Fused filament fabrication of ceramic (FFFC) for the production of test samples. The study investigates the effects of different production strategies on three types of ceramic materials: experimental ceramic composite fiber (e.c.c.f.)(composite material produced by STU FCHPT), Zirconium Silicate, and White Zirconia. The primary objective is to compare the production times of the different strategies and investigate their effects on the properties of the samples. This research is important because production time is a crucial factor in the manufacturing industry, and minimizing production time without compromising quality is essential. The study aims to explore the impact of various production strategies on the production time and properties of the test samples, such as hardness, porosity, and flexural strength. The experimental procedure involves printing test samples using a MakerBot METHOD X 3D Printer with FDM technology and varying the layer thickness, raster angle, infill density, and other production strategies. The study aims to identify the optimal production strategy for each ceramic material, which can significantly reduce production time while maintaining the desired quality of the parts. Overall, the research provides valuable insights into the optimal production strategies for different types of ceramic materials and contributes to the development of novel, cost-effective, and efficient manufacturing processes for ceramic composites.

Para ello, propongo que se realice una interpretación sistemática del Código Procesal Penal, seguido de un control de legalidad, constitucionalidad y convencionalidad, a fin de garantizar una real y efectiva tutela a los menores de edad, víctimas de delitos contra la libertad sexual, dado que la realidad normativa no siempre es lo mismo que la realidad práctica, más aún cuando se trata de proteger a sujetos de especial vulnerabilidad, como son los menores de edad.  Aplicable solo para casos excepcionales, donde se haya respetado el derecho de la defensa, debiendo priorizarse la aplicación de la prueba anticipada.
Old German Baptist Brethren: Plain but Different, Part 1
Authors: Walsh Tony , Bach Jeff , Funkhouser Sam
Published: May 2023

This article utilizes a narrative methodological research paradigm to explore perceived distinctions between the Old German Baptist Brethren (the main Old Order expression of the Schwarzenau Brethren) and other Plain groups. The authors explore three areas of specific distinction: (a) The group’s weave of Pietist as well as Anabaptist historical and theological influences, (b) a strong emphasis on the ritualized enactment of a discrete array of ordinances, (c) an emphasis on orthopraxis rather than doctrinal uniformity as a marker of church unity. All these, together with four other areas addressed in the second part of the article, combine to create a distinctive and unusual expression of Plain spirituality and life practice.

Psoriasis area and severity index (PASI) was calculated for all patients with psoriasis and disease activity score (DAS28-CRP) in all arthritis patients. The control group had 150 age and sex-matched participants without any symptoms related to psoriasis or psoriatic arthritis. The 25 (OH) vit D3 serum level was estimated for both groups. This is an observational, cross-sectional study.
Results: Out of total 100 patients, 55% were male and 45% female, with mean age and disease duration 49.7±6.7 years and 11.4±3.5 years, respectively. The control group had 150 subjects (86 males, 64 females). The 25 (OH) vit D3 levels of both patients and controls were 19.2±8.5 ng/ml and 29.9±6.7 ng/ml, respectively and the difference was statistically significant (p<0.05). The 25(OH) vit D3 levels were 21.9±4.1 ng/ml in patients with disease duration <10 years, and 15.9±4.2 ng/ml in patients with disease duration ≥ 10 years and difference was statistically significant (p<0.05). It was 18.9±7.8 ng/ml and 20.1±8.4 ng/ml respectively in psoriasis patients with and without arthritis but the difference was statistically not significant (p>0.05). The 25(OH) vit D3 level was lower in psoriasis with high PASI compared to psoriasis with low-moderate PASI and lower in psoriatic arthritis with high disease activity compared to arthritis with low-moderate disease activity.
Conclusions: Both psoriasis and psoriatic arthritis patients had lower 25 (OH) vit D3 levels. The disease durations were directly related to 25 (OH) vit D3 insufficiency. Lower levels were associated with higher active diseases.

Published: May 2023

Background: Type 2 diabetes mellitus (T2DM) significantly increases morbidity and mortality from cardiovascular disease. The present study was conducted to know the effect of thiazolidinedione and SGLT2 inhibitor on glycemic control, blood pressure and lipid profile and effect on cardiovascular mortality in T2DM.
Methods: A total 80 patients of aged ≥40 years with T2DM were included and divided into 4 groups based on ongoing treatment i.e., (lifestyle modification + Tab metformin 500mg BD) + 1) Tab metformin 500mg; 2) Tab dapagliflozin 10mg OD; 3) Tab pioglitazone 15mg OD; 4) Tab pioglitazone 15mg OD + Tab Dapagliflozin 10mg OD.
Results: The change in FBS, PLBS and HbA1C from pre-intervention to post-intervention was highest in the patients with DAPA + pioglitazone group followed by patients with pioglitazone group then the patients with DAPA group and lowest in patients with metformin group. There was a statistically significant difference between them, (p<0.001). The weight reduction was highest in the patients with DAPA 10mg group followed by patients with metformin group, (p<0.001). The change in SBP, DBP and change in lipid profile (triglyceride and cholesterol, LDL and HDL) from pre-intervention to post-intervention was highest in the patients with DAPA+ pioglitazone group. This change was statistically significant (p<0.001).
Conclusions: The combination of pioglitazone and dapagliflozin not only helped in glycemic control but also had reduction in blood pressures, improvement in the lipid profile and caused slight weight reduction. There were no major adverse drug reactions, and no MACE was observed during the study. Hence this combination of pioglitazone and dapagliflozin may reduce the cardiovascular mortality (which needs longer duration study).

Pulmonary pleomorphic carcinoma (PPC) is an uncommon primary lung tumor with a low incidence and aggressive biological characteristics that can occur in young people and nonsmokers. Pleomorphic carcinoma (PC) has a worse prognosis than other non-small cell lung tumors. We describe a 45-year-old man who complained of having a dry cough for a month. A well-defined mass in the anterior section of the left lower lobe was identified by chest high-resolution computed tomography (HRCT), and a positron emission tomography (PET) scan confirmed a left lobulated tumor with fluorodeoxyglucose (FDG) uptake in the left mediastinal lymph nodes. An endobronchial ultrasound guided transbronchial needle aspiration (EBUS TBNA) guided biopsy of the tumor was performed and sent for histopathological analysis, which identified pleomorphic squamous cells and giant cells. Positive IHC markers included P63, TTF1, pancytokeratin, Vimentin. Patient was diagnosed with stage IIIa (T3N2M0) pleomorphic carcinoma of the lung. Due to the tumor's advanced stage, the patient received chemotherapy and radiation therapy.
Neuromyelitis optica and liver cirrhosis: an association or co-incidence
Authors: Kumar Arjun , Das Ananya , Agarwal Mayank , Raina Rohit , Kant Ravi
Published: May 2023

Neuromyelitis optica (NMO) is a rare central nervous system demyelination syndrome predominantly targeting optic nerves and the spinal cord. Here we present a middle-aged female presenting with new onset quadriparesis and a history of persistent splenomegaly and pancytopenia, eventually being diagnosed as NMO along with autoimmune cirrhosis. The association of NMO spectrum disorders (NMOSD) with chronic liver disease has not been previously described in the literature. The purpose of this case report is to bring forward an unusual presentation and to ascertain whether it could be part of a heterogenous spectrum of an autoimmune disorder, or merely a co-incidence.

Published: May 2023

Background: Our current treatment of an appendiceal mass is initially conservative, followed by an interval appendectomy. The necessity of this routine interval appendectomy is debatable.  Aim was to evaluate whether surgical factors and pathological features of the excised appendices support interval appendectomy.
Methods: It was a retrospective study conducted for a period of 5 years (2017-2022). To assess the number of patients with appendicitis and a peri-appendiceal mass, all patients in both hospitals encoded for appendicitis were listed. Over this period of 5 years a total of 2,090 patients were diagnosed with acute appendicitis. Of these, 230 patients were operated through Interval appendectomy. All medical records of these patients were then reviewed and relevant variables were registered.
Results: It was found that clinical findings alone were not specific enough to diagnose an appendiceal mass; 47% had a palpable abdominal mass and the median temperature was 38.2°C ranging from 36 to 40.5°C. Ultrasound examination was done in 70% of patients and showed an appendiceal mass in 72%. During the interval period, 4 patients presented with an appendiceal mass needing drainage, and 3 with acute appendicitis requiring emergency appendectomy. 
Conclusions: We conclude that when causes for the appendiceal mass other than appendicitis are excluded, interval appendectomy seems unnecessary in patients who respond well to initial conservative treatment.
A retrospective audit of robotic versus laparoscopic anterior resection for diverticular disease in a single surgeon’s experience
Authors: Chiu Tricia R. , Chen Michelle Z. , Guo Cici Z. , Barto Walid
Published: May 2023

Background: There has been a shift towards elective resection for recurrent or complicated diverticular disease to prevent recurrent episodes of diverticulitis. Our study aims to compare the outcomes in elective robotic and laparoscopic anterior resection for diverticular disease by a single surgeon experienced in both techniques.
Methods: This is a retrospective study of patients who underwent elective anterior resections at Nepean Public Hospital, Nepean Private Hospital, and Sydney Adventist Hospital (SAN) in the last 10 years. The single surgeon is an experienced surgeon who has performed laparoscopic anterior resections from January 2013 to December 2018; and mainly robotic anterior resections from January 2018 to July 2022. The primary outcome of this study was to determine if there were any differences in length of stay and post-operative complications in laparoscopic and robotic anterior resections. Secondary outcome measures included operating time, rate of conversion to open surgery, and 30-day mortality and morbidity.
Results: There were 53 patients included in this study. There was no significant difference in conversion to open rates (p=0.528), mean operative time (p=0.095), stoma formation rates (p=0.528) and post-operative complication rates (0.609). Length of stay was significantly shorter in the robotic group (p=0.024), and a higher proportion of patients who had laparoscopic surgery stayed for ≥6 days (p=0.08). There were no anastomotic leakages, or 30-day mortality and morbidity.
Conclusions: Robotic anterior resection is a feasible approach in experienced hands and produces comparable results to laparoscopic anterior resection for diverticular disease in terms of length of stay, post-operative complications, and operative timings.
Outcome of uncommon intestinal foreign bodies in pediatrics
Authors: Daboos Mohammad , Salama Ahmed
Published: May 2023

Background: Foreign body (FB) ingestion in children is very common. Children can ingest a wide variety of Foreign Bodies. Most FBs pass spontaneously through the gastrointestinal tract. Other FBs, especially uncommonly ingested objects, can present with complications and need intervention to be extracted. The aim of the study was to highlight the importance of closed observation, proper investigation, and timely intervention for uncommon gastrointestinal FBs.
Methods: This was a prospective study, conducted at pediatric surgery department, Al-Azhar University Hospitals, between November 2020 and September 2022, that included all patients who presented to our department with variously ingested FBs, were prospectively evaluated to detect those who needed surgical intervention to extract these FBs.
Results: During the specified time period, 86 patients with FB ingestion presented to our hospital. Out of these children, four patients ingested uncommon FBs, presented with symptoms of complications, and needed intervention to extract these FBs. One patient swallowed magnet tools; two patient’s swallowed toothpicks; and one patient swallowed a needle with a necklace, which was impacted in the small bowel and surgically removed.
Conclusions: Children who ingest uncommon FBs are more likely to present with complications of impaction or perforation. Negative plain films are not sufficient to conclude conservative treatment especially for radiolucent FBs. CT should be done to rule out retained and radiolucent foreign bodies; closed observation and timely intervention are mandated to avoid serious complications.
