Intervention of rarely seen catheter loss during permanent tunneled hemodialysis catheterization: A case report
Authors: Emced Khalil
Published: August 2020

Introduction: In patients with end-stage renal disease (ESRD), permanent hemodialysis catheters are often used by performing percutaneous catheterization to create a permanent vascular access. To the best of our knowledge, no cases with accidental loss of catheter piece during hemodialysis catheter replacement or during its retrieval under scopy has been reported in the literature yet. Case report: It was decided to retrieve the right permanent dialysis catheter of a 54-year-old woman, who had received a temporary dialysis catheter due to the development of catheter site infection in her 3rd permanent catheter (the first two were changed due to thrombosis). Due to excess adhesion in the region, the retrieval of the catheter was complicated, only half of it (proximal piece after cutting into two) was removed, while the distal section slipped and migrated to the right subclavian vein, up to the right atrium. The diagnosis was confirmed by chest radiographs showing that the distal piece of the catheter piece was in the right subclavian vein and right atrium. The catheter piece was retrieved through a minor invasive procedure made possible by scopy without any further complications. Conclusion: Permanent dialysis catheters should ideally be placed under scopy. Also, when the retrieval of a catheter is planned, cutting from any part of the catheter should never be performed.
Pain management of newborn with Epidermolysis bullosa for wound dressing: A case report
Authors: Seyhan Balli
Published: August 2020

Epidermolysis bullosa (EB) is a genetic disease characterized by blisters on the skin and mucous membranes as a result of mechanical fragility. There are four types of EB: simplex (EBS), junctional (JEB), dystrophic forms (DEB), and Kindler syndrome. Simple analgesics such as paracetamol and ibuprofen in EB are also sufficient to reduce pain. Opioids and anxiolytics are necessary for severe pain during wound dressings. In this report, a case of JEB and its pain management at home during dressing by an anesthetist is presented.

Authors: Mulić Mersudin , Lazović Biljana , Dmitrović Radmila , Jovičić Nevena , Detanac Džemail , Detanac Dženana
Published: August 2020

Introduction: It is generally accepted that physical activity benefits every person but athletes diagnosed with asthma face various challenges during their training to keep the symptoms of the disease under control. Prolonged exposure to agents in the environment in which athletes train favors the development of permanent changes in the airways. Their action leads to permanent hyper-reactivity with development of an inflammatory response and the release of mediators (IL-8, leukotrienes, eicosanoids) that lead to damage epithelial cells with breaking connection between them and consequent dysfunction of the respiratory system. This condition is called exercise-induced asthma (EIA). This fact is especially important for athletes who have long endurance training. The best way to check the condition of breathing system is with a diagnostic method which is the " gold" standard spirometry. Aim: The point of this systematic review is to get closer the mechanism occurrence of EIA/(exercise-induced bronchoconstriction)-EIB, prevalence and incidence of EIA/EIB, changes of pulmonary function and quality of life in elite athletes. We searched papers from PubMed and Cochrane database using keywords: 'exercise-induced asthma', 'athletes', 'spirometry', 'bronchoconstriction', 'bronchospasm', 'physical activity', 'physical training', 'prevalence', 'incidence'. We have studied 48 scientific papers in total. Conclusion: The prevalence of asthma among elite athletes, especially endurance athletes is higher than in general population. The explanation of this phenomenon is related to the whole mechanism of occurrence, it is still insufficiently clarified, but one thing is for sure that with good disease control athletes can play and compete undisturbed for many years.
Postoperative survival results of patients with stage I-II malignant pleural mesothelioma in an endemic area
Authors: Kermenli Tayfun , Azar Cebrail
Published: August 2020

Introduction: The accepted treatment option for malignant pleural mesothelioma (MPM) is multimodality treatment including surgery, chemotherapy and radiotherapy. In this study, we aimed to evaluate the results of patients who underwent surgical resection for multimodality treatment due to MPM at our clinic between July 2015 and October 2019. Method: The results of 13 patients who underwent surgical treatment for MPM in our clinic were evaluated retrospectively. Patients' demographic structure, regions where they live, symptom presentation, disease localization, biopsy diagnosis, type of surgical treatment, choice of neoadjuvant or adjuvant chemotherapy, postoperative complications and survival outcomes were evaluated. Results: The mean survival time was 19.6 months. Six patients were still under follow-up. One patient whose postoperative pathology was reported as mixed type had the worst survival with 13 months and the best survival was 32 months in the patient who underwent postoperative hyperthermic chemotherapy with pleural decortication. Four patients died due to local recurrence and general condition disorder, and two patients died after peritonitis carcinomatosis and ascites. Conclusion: Epitheloid type multimodality treatment and intrapleural hyperthermic chemotherapy may be a good choice in patients with the stage I and II malignant mesothelioma without surgical comorbidity
Una propuesta metodológica para identificar gentrificación a partir de los censos de población
Authors: Díaz Parra Ibán , Apaolaza Ricardo
Published: August 2020

En el actual cuerpo de estudios sobre gentrificación en América Latina han predominado los estudios de caso centrados en áreas focalizadas y con un tratamiento predominantemente cualitativo. Ante este escenario, uno de los retos presentes es desarrollar metodologías que permitan trabajar en escalas mayores, que sean replicables y que permitan establecer comparaciones, sin por ello renunciar a los estudios de caso en profundidad. La bibliografía internacional muestra las potencialidades de la estadística censal para este menester, la necesidad de combinar variables de estatus social y condiciones de la vivienda, así como la pertinencia de entender el proceso como un cambio relativo de zonas específicas con respecto del conjunto de la ciudad y con una temporalidad amplia. A partir de estas ideas, se recurre a los censos de población y vivienda en la Ciudad Autónoma de Buenos Aires y se propone una metodología que cumple con la doble función de identificar áreas con indicios de procesos de gentrificación en curso, así como de reconocer posibles características sociohabitacionales que las harían potencialmente más “gentrificables”. El texto concluye señalando la factibilidad de la metodología propuesta, así como la necesidad de examinar las potencialidades y limitaciones de cada censo nacional cuando se realizan comparaciones entre distintos países.

Innocence is Not Enough: The Public Life of Death Row Exonerations
Authors: Sarat Austin , Morgan Natalie , Grimes Willa , Narcisse Obed , Thomas Jeremy
Published: August 2020

Miscarriages of justice and wrongful convictions are a pervasive reality in America's criminal justice system. In this paper we examine news coverage of miscarriages of justice in the death penalty system and the release of death row inmates to understand what we call the public life of exonerations. We examine the way newspapers tell the story of exonerations and the various tilts and tendencies that characterize their presentations. We focus on the five states which, from 1972–2019, had ten or more exonerations. During that period, they were Florida, Illinois, Texas, Louisiana, and Oklahoma. We conclude that the public discourse surrounding exoneration, while providing evidence of the death penalty system's most consequential flaws, serves as much to preserve that system as to challenge it.

Authors: Cesur Aydin , Demirel Oğuzhan , Altan Salli , Özcan Mutlu
Published: August 2020

Background/Aim: The aim of the present study is to evaluate diagnostic accuracy of two generic image receptors with CMOS and PSP sensors for image quality scoring (IQS), burnout incidences (BI) and cervical widths (CW) with regard to four different exposure times. Material and Methods: 43 incisor teeth within 15 paraffin block models were exposed at 4 different exposure times both for the CMOS and PSP groups, and a total number of 120 images were obtained. All images were evaluated by 3 dentomaxillofacial radiologists via 3 different criteria; IQS, BI, CW. Results: Diagnostic quality scorings between groups displayed statistically significant difference for 0,1; 0,125 and 0,16 SEC exposure times. PSP group revealed higher IQS. For 0,125 and 0,16 seconds exposure times, PSP group showed higher percentages of BI. Average CW were lower in PSP group. Although no statistically significant difference was found between average CW vs. exposure times in the CMOS group; PSP group revealed significant differences among exposure times. We can state that, the PSP system displayed higher image quality so exposure times can be reduced, alas, the same conclusion is not possible with CMOS system used. Conclusions: Image quality perception is higher in PSP system we used, compared with CMOS system. PSP system display more burnout effects with increasing exposure times, while CMOS system is constant.

Published: August 2020

Background/Aim: Gingival recession is defined as apical migration if the gingival margin associated with exposure of the cement-enamel junction. The gingival recessions are major esthetic concern in patients at any age. In cases with esthetic and functional considerations mucogingival surgery is indicated. The advantages of CAF with or without CTG are making this procedure highly recommended in the esthetic zone. The results are predictable about root coverage, widening if the gingival tissues and esthetics. The aim of the recent case report is to demonstrate the successful combination of coronally advanced flap with connective tissue graft in the treatment of wide and deep gingival recessions. Case Report: Female patient seeking consultation with great concern" not to lose the lower canines". She noticed elongation of the teeth in the recent years complained with tenderness while brushing them. The initial examination showed presence of multiple gingival recessions in the upper and the lower jaw. Full periodontal status was taken and following diagnosis was established - dental plaque induced gingivitis, class IІ gingival recession in teeth #33 and #43 (Miller`s classification), RT1 by Cairo. After cause-related therapy two surgical procedures were performed in separate sessions. Both gingival recessions were surgically treated by means of CAF with CTG. Conclusions: Despite the limitating factors such as lack of keratinized tissue in the patient's mandible that rather difficult the performance of the technique of choice, the coronally advanced flap with connective tissue graft is predictable technique for full root coverage.

Authors: Chojnowska-Ćwiąkała Izabela , Świerczyńska Justyna , Weryszko Małgorzata , Szpringer Monika
Published: August 2020

Aim: The aim of this article is to discuss the difficulties and complexities of the bipolar affective disorder (BPAD) diagnostic process in an adolescent. The case of suspected occurrence of bipolar affective disorder in an adolescent who was diagnosed with attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) in childhood was presented.

Case report: A 16-year-old boy was treated in the past for ADHD and ODD. The reason for the current admission to the pediatric psychiatry ward was the behavioral change that disturbed the caregivers: he has become more restless, irritable, explosive. A few nights prior to hospitalization, he was very agitated, chaotic, physically and verbally aggressive.

At admission he was disorganized, tense, in strong hand manipulation anxiety. He displayed alternating attention and loquacity. His statements were chaotic, his thinking accelerated. He displayed grandiose delusions. He was uncritical.

After the treatment, mood, psychomotor drive and circadian rhythms stabilisation were achieved. Discharged from the ward with the recommendation of further outpatient treatment and continuation of psychotherapeutic interactions.

Conclusions:

1.

The diagnosis of bipolar affective disorder in adolescents is a complex and difficult process. The expression of symptoms of this disorder during adolescence is different than in adults.

2.

Differential diagnosis of bipolar affective disorder for a 16-year-old boy should also consider both past ADHD and ODD and their possible sequelae should be taken into account, as well as the risk of abnormal personality development.

3.

Due to the high dynamics of changes associated with the adolescence period, further pharmacological treatment of bipolar affective disorder should be combined with psychotherapeutic interventions.
Diversity of parasites from Xenopus laevis (Amphibia: Pipidae) and their seasonal rate of infection in selected habitats in the Limpopo Province, South Africa
Authors: Mbokane E. M. , Theron J. , Luus-Powel W. J.
Published: August 2020

This study determined the diversity and seasonality of parasites species of the African clawed frog, Xenopus laevis (Daudin, 1802), from three localities, namely Modjadjikloof, Mokopane and University of Limpopo, Limpopo Province, South Africa. A total of seven parasite species were collected and identified. They included two nematodes, Camallanus kaapstaadiSouthwell & Kirshner, 1937 and Batrachocamallanus slomei (Southwell & Kirshner, 1937), a monogenean, Protopolystoma xenopodis (Price, 1943), a cestode, Cephalochlamys namaquensis (Cohn, 1906), a protozoan, Trichodina xenopodosFantham, 1924, two digeneans, Progonimodiscus doyeri Ortlepp, 1926 and Dollfuschella rodhainiVercammen-Grandjean, 1960. The most common and abundant parasite species by far were Cm. kaapstaadi, B. slomei and Cp. namaquensis, with Cm. kaapstaadi, B. slomei present in all localities. Trichodina xenopodos was a rare species, only present in host populations from Modjadjiskloof. Modjadjiskloof had the highest species richness (all seven parasite species) followed by Mokopane (five parasite species) and University of Limpopo (3 parasite species). There were also higher infection levels (prevalence and mean intensity) of Cm. kaapstaadi, B. slomei, Cp. namaquensis and Pt. xenopodis in hosts from Modjadjiskloof while Pd. doyeri and D. rodhaini infection levels were greater in Mokopane. The variability between localities shows that parasites with heteroxenous life cycles are more strongly associated with more pristine habitats. The variability in calculated indices (prevalence and mean intensity) also suggests that the occurrence of some of the parasites is affected by season, favouring higher infection rates during summer. This suggests that temperature has a direct role in the reproductive and developmental processes of these parasites. Neither length nor sex had an influence on the prevalence or intensity of parasites.

Published: August 2020

Big Data has become a significant concern of the world, along with the era of digital transformation. However, there are still many young people, especially in developing countries, who are not yet aware of the security of their big data, especially personal data. Misuse of information from big data often results in violations of privacy, security, and cybercrime. This study aims to determine how aware of the younger generation of security and privacy of their big data. Data were collected qualitatively by interviews and focus group discussions (FGD) from. Respondents were undergraduate students who used social media and financial technology applications such as online shopping, digital payments, digital wallet and hotel/transportation booking applications. The results showed that students were not aware enough and understood the security or privacy of their digital data, and some respondents even gave personal data to potentially scam sites. Most students are not careful in providing big data information because they are not aware of the risks behind it, socialization is needed in the future as a step to prevent potential data theft.

Authors: Frenkel Michael , Zimmermann Lilli
Published: August 2020

This article reviews several hypotheses that aim at explaining the development of German merchandise exports. Based on cointegration estimation techniques, we examine different determinants for their ability to explain German exports during the period 1992–2016. The estimation results indicate that, in addition to the traditional determinants (world demand and price competitiveness), other determinants, such as energy prices and the increasing fragmentation of production processes, are also crucial in explaining German exports.
The Determinants of Indonesia’s Business Cycle
Authors: Harahap Berry A. , Bary Pakasa , Kusuma Anggita Cinditya M.
Published: August 2020

This study investigates the determinants of Indonesian’s business cycle using the global vector autoregressive (GVAR) approach, by including spillover responses within 33 countries with 2000 bootstrap replications. The results show that Indonesia’s business cycle is influenced by both domestic and external factors. In addition to exogenous shocks from output, the dominant domestic factors are monetary policy and price competitiveness. The dominant external factors are global economic activity and liquidity conditions, particularly those originating from the Chinese economy. Spillovers from a number of economies appear to shape Indonesia’s economic fluctuations. The paper discusses such relevant spillovers.

Authors: Laliotis George P. , Koutsouli Panagiota , Sotirakoglou Kyriaki , Savoini Giovanni , Politis Ioannis
Published: August 2020

Introduction

The aim of this study was to determine changes of reactive oxygen species (ROS), serum antioxidant capacity (SAC), oxidative stress index (OSi), and α-tocopherol (α-T) during the periparturient period in healthy and mastitic cows and to further investigate whether these parameters can be used as a tool for identifying cows at higher risk of developing mastitis.

Material and Methods

Blood samples from 110 dairy cows from two commercial farms were obtained at dry-off, calving, and 30 days post-partum. Healthy cows formed group A (n = 90) and mastitic cows B (n = 20). Blood serum was obtained by centrifugation, and the aforementioned parameters were determined. A general linear model was used for analysing the associations among the determined blood parameters, the health of the animals’ udder, and the sampling time.

Results

ROS and OSi values were higher (P < 0.001) by a respective 14% and 26%, and SAC values lower (P < 0.001) by 10% in group B than in group A at calving. ROC curve analysis revealed that all determined parameters at calving and α-T at dry-off and 30 days post-partum had excellent or acceptable predicting ability for mastitis incidence.

Conclusion

This information provides a tool for early identification of cows at high risk of developing mastitis, allowing the implementation of intervention strategies.

Authors: Todorov S. S. , Deribas V. Yu. , Kaz’min A. S. , Todorov S. S.
Published: August 2020

Aim. To describe a rare occurrence of ﬁbromuscular vasa vasorum dysplasia of the aortic aneurysm wall.

Materials and methods. Surgical material from the ascending aortic aneurysm wall was examined. Longitudinal strips of the aortic wall were excised for histological examination with subsequent 24-h ﬁxation in 10% buffered formalin. A histological isopropanol assay was performed with an automated Logos microwave tissue processor (Milestone, Italy) with subsequent sample embedding into parafﬁn. Sections were obtained with a rotary microtome (Leica, Germany). Staining was performed with haematoxylin-eosin, van Gieson’s picrofuchsin, orcein for elastic ﬁbres, Hotchkiss’ PAS reaction with alcian blue for glycosaminoglycans. Histological and histochemical properties of the aortic wall were studied and imaged with a Leica DM 1000 microscope (Germany) equipped with a camera ICC50 E at magniﬁcations 40x, 100x, 200x, 400x.

Results. The conducted histological examination of the aortic aneurysm wall revealed most pronounced changes in media and adventitia layers. Elastic ﬁbres in media were swollen, homogeneous, crimped, with pronounced dystrophic and necrobiotic changes in smooth myocytes. Regions of compromised cells and elastic ﬁbres in media contained pockets of alcian-positive glycosaminoglycans. Speciﬁc changes were revealed in adventitia vasa vasorum in the form of a pronounced wall thickening and lumen narrowing due to dysplastic ﬁbromuscular tissues.

Conclusion. A rare form of ﬁbromuscular dysplasia of the vasa vasorum of the ascending aortic aneurysm wall observed in a 43 years-old woman demonstrated the morbid morphology of smooth myocytes, as well as ﬁbrous collagenous and elastic structures. The described features were likely associated with the aortic wall trophic structure and aneurysm morphogenesis.
Integrated curriculum: a contemporary innovation strategy in medical education
Authors: Osadchii O. E.
Published: August 2020

In its traditional form, medical education begins with learning basic science disciplines, with subsequent transition to clinical training. The basic sciences are taught as a series of separate academic courses, with no coordination applied at the inter-disciplinary level. During past decades, the integrated curriculum has become increasingly popular as a novel instructional strategy that promotes contextual learning in medical practice. The curriculum breaks down the barriers between basic and clinical sciences (vertical integration), interconnects teaching of various basic science disciplines (horizontal integration) and facilitates the acquisition of critical thinking, problem-solving and team-working skills through collaborative learning. The vertical integration is encouraged with training in clinical and communication skills starting in the ﬁrst semester, teaching basic sciences at the interface with medical problems and involving clinicians in giving lectures on applied anatomy and clinical physiology. In order to facilitate the horizontal integration, basic science disciplines are taught concurrently within interdisciplinary units aligned around the body organ systems. This contributes to a better understanding of complex interrelations between structure and function and stimulates wider insights into mechanisms of the disease. The integrated curriculum supports conceptual learning rather than simple memorisation of fragmented factual knowledge. As such, it relieves the information overload imposed on students due to a rapid growth of medical knowledge in the contemporary world. With the integrated curriculum, the main emphasis is placed on problem-oriented learning guided by an experienced tutor in a small group of students. In this setting, a realistic medical case is used as a trigger for discussion aimed at linking basic science concepts with the clinical problem. Through collaborative problem-solving, students develop a clinical reasoning and team-working skills. Overall, problem-based learning puts forward a student-centred approach in a sense that students themselves are primarily responsible for identifying relevant learning objectives and self-guided acquisition of medical knowledge. This raises their motivation in learning basic sciences and markedly improves the perception of learning environment. In summary, the integrated curriculum offers a number of beneﬁts to medical students and appears to provide an effective instrument in developing professional competencies required in clinical work.
Dermal response to combined double ﬁller administration

Published: August 2020

Aim. This experimental work presents a comparative assessment of the effect of hyaluronic acid and crystalline calcium hydroxyapatite on derma in separate and combined application setting.

Materials and methods. The study used rats (30 animals) for subdermal injection of 0.05 ml medium. Group 1 was administered calcium hydroxyapatite (Radiesse (Merz, Germany)), group 2 received hyaluronic acid (Restylane (SabQ, Sweden)) and Group 3 — both preparations combined in ratio 1:1 (Mix). Results were evaluated 4 months after the ﬁller injection. Sections were stained with haematoxylin–eosin, van Gieson’s and Masson’s trichrome techniques. Collagen types I and III were detected with polyclonal antibodies (Abcam, England). Fibroblasts were positively identiﬁed with vimentin (LabVision), macrophages — with CD68 (LabVision) tagging. Effect of extracellular matrix remodelling was studied with α-SMA actin (Abcam, England).

Results. We demonstrate that separate ﬁlling of hyaluronic acid and calcium hydroxyapatite produces different response mechanisms, while their combined administration does not lead to a marked voluming of the dermal extracellular matrix.

Conclusion. Combined administration of the two ﬁllers under study may facilitate a prolonged effect of their combined action exceeding 4 months, due to the absence of ﬁbrosis, complications and side effects.

Objetivo: Analisar como a produção científica aborda a relação entre a gestação na adolescência com o desfecho da prematuridade. Métodos: Revisão integrativa nas bases de dados Biblioteca Virtual em Saúde (BVS) e Scientific Eletronic Library Online com os descritores Adolescência AND Prematuridade. Trata-se de uma pesquisa vinculada ao Núcleo Interdisciplinar de Estudos de Vulnerabilidade e Saúde da Universidade Estadual de Feira de Santana, na Bahia. A coleta de dados ocorreu entre março e abril de 2020, foram selecionados 2.838 artigos inicialmente e após os critérios de inclusão totalizaram 7 artigos. Resultados: Os artigos revisados apresentaram divergências na abordagem da gravidez precoce com a incidência de prematuridade, evidenciando a influência do pré-natal e do nível de escolaridade no desfecho desse fenômeno. Considerações finais: Os riscos obstétricos e fetais só serão diminuídos quando houver uma rede de apoio direcionada às adolescentes, que foquem na atenção reprodutiva, pré-natal e suporte psicológico e social.

Published: August 2020

Objetivo: Analisar a influência da deficiência de Vitamina D no desenvolvimento do diabetes mellitus. Métodos: Trata-se de uma revisão integrativa da literatura, ou de fonte secundária. Realizou-se levantamento bibliográfico de artigos nas bases de dados: Scientific Eletronic Library Online (SciELO), Bases de Dados da Literatura Latino Americana em Ciências de Saúde (LILACS), base de dados PubMed, da US National Library of Medicine e Google Acadêmico, no período de 2008 a 2018, com o uso dos descritores: “Vitamina D”, “Diabetes Mellitus” e “Deficiência de Vitamina D”. Resultados: A insuficiência de Vitamina D tem sido relatada em todo o mundo e em todos os grupos etários nos últimos anos e tem sido considerada um problema de saúde pública, uma vez que níveis reduzidos de Vitamina D se mostraram relacionados a várias doenças crônicas, como diabetes mellitus tipo 2, obesidade e hipertensão. A Vitamina D está relacionada à homeostase e ao bom funcionamento do sistema imunológico. Considerações finais: Conclui-se que a Hipovitaminose D é um achado constante em pacientes que apresentam diabetes mellitus e que essa relação é inversamente proporcional ao tempo e ao agravamento da doença.

Objetivo: Compilar evidências científicas recentes sobre as adaptações fisiológicas que ocorrem no coração de atletas amadores. Revisão bibliográfica: A prática de exercícios físicos proporciona um aumento do trabalho cardíaco para suprir a demanda metabólica, o que pode provocar adaptações fisiológicas a depender de vários fatores, como o tipo de exercício realizado, sendo esse predominantemente de força, resistência ou misto. Com a popularização da prática de atividades físicas por pessoas que não dependem do esporte como fonte de renda, os atletas amadores, tornou-se significativo a análise de registros de adaptações cardíacas fisiológicas induzidas pelo exercício que podem ocorrer nesses indivíduos. Com isso, foi possível observar as principais adaptações em praticantes de exercícios de resistência, que incluem as adaptações morfológicas do coração, no sistema de condução do impulso elétrico, além de adaptações bioquímicas e funcionais do sistema cardiovascular. Já as induzidas pelos exercícios de força, incluem predominantemente as adaptações morfológicas e funcionais, enquanto as desenvolvidas pela prática de exercícios mistos incluem alterações funcionais, morfológicas e elétricas. Considerações finais: Percebe-se a necessidade de um maior monitoramento cardiológico em atletas amadores, tendo em vista o risco aumentado de complicações cardiovasculares nesses atletas.

Introdução: A coalizão tarsal representa uma comunicação anormal entre ossos do tarso e pode ser óssea, cartilaginosa ou fibrosa, se desenvolvendo de forma secundária a insuficiência da diferenciação e segmentação do mesênquima primitivo nas primeiras fases do desenvolvimento, diminuindo a mobilidade e deformando os pés, quando congênita. Quando adquirida ocorre devido à artrite inflamatória, infecção, trauma, neoplasia, entre outras causas. Relato de Caso: Relatamos o caso de uma mulher de 37 anos com queixa há um mês, desmontando a importância da investigação da causa e a necessidade de atenção por parte do radiologista para a avaliação das coalizões tarsais visto que, uma coalizão, independentemente de quais ossos envolvidos, pode levar a uma sintomatologia limitante. Palavras chave: Ossos do tarso, Coalizão tarsal, Imagem por ressonância magnética, Deformidades do péAbstractIntroduction: Tarsal coalitions represent abnormal bridging between tarsal bones and can be osseous, cartilaginous, or fibrous, developing secondary to failure of differentiation and segmentation of the primitive mesenchyme in the first stages of development, decreasing mobility and deforming the feet, when is congenital. When acquired it occurs due to inflammatory arthritis, infection, trauma, neoplasia and other causes. Case report: We report the case of a 37-year- -old woman with a complaint a month ago, dismantling the importance of investigating the cause and the need for attention by the radiologist for the evaluation of tarsal coalitions since, a coalition, regardless of which bones involved, can lead to limiting symptoms.Keywords: Tarsal bones, Tarsal coalition, Magnetic resonance imaging, Foot def
