Résumé
As with Amazonian primates, mixed associations between species in the Atlantic Forest are also influenced by ecological factors. However, Atlantic Forest primates may face additional challenges, such as isolation pressures and fragmentation of forest habitats, which may increase the frequency of these arrangements. The main of this work is to report a sympatry with possible interaction between individuals of two species of primates of the Pitheciidae and Callitrichidae families: Callicebus nigrifrons (Spix 1823) and Callithrix aurita (É. Geoffroy Saint-Hilaire 1812) in an urban park in the south of the state of Minas Gerais. Individuals were observed interacting during foraging and displacement. The association of individuals of the two species can be explained by the low quality of the forest fragment, as it can increases the chances of obtaining food resources and configures a dilution strategy against predator attacks.
Assim como ocorre com os primatas amazônicos, as associações mistas entre espécies na Mata Atlântica também são influenciadas por fatores ecológicos. No entanto, os primatas da Mata Atlântica podem enfrentar desafios adicionais, como pressões de isolamento e fragmentação de habitats florestais, que podem aumentar a frequência desses arranjos. O objetivo deste trabalho é apresentar um relato de simpatia com possível interação entre indivíduos de duas espécies de primatas das famílias Pitheciidae e Callitrichidae: Callicebus nigrifrons (Spix 1823) e Callithrix Resumo aurita (É. Geoffroy Saint-Hilaire 1812) em um parque urbano no sul do estado de Minas Gerais. Foram observados indivíduos interagindo durante o forrageio e deslocamento. A associação de indivíduos das duas espécies pode ser explicada devido à baixa qualidade do fragmento florestal, pois pode aumentar as chances de obter recursos alimentares e configura uma estratégia de diluição de contra-ataques de predadores.

Abstract This study assessed the anthelminthic feed additive albendazole effect on the main indicators of the quality of sheep meat obtained from infected and deworming animals. A total of 20 heads of Akzhaik meat and wool sheep (i.e. 2 years of age, of different sex) were used in a 20-day experiment and 2 groups of 10 heads were formed (n = 4). The sheep were fed with the basic diet (i.e. control, group CON), without adding anything, and the second group was fed the basic diet orally with the addition of a dose of 1.2 g / head (an experimental group). At the end of the experiment, a control slaughter was carried out from each group in order to study the biochemical composition of meat and its quality. The anthelmintic feed additive albendazole did not have a significant effect on the indicators (organoleptic and physicochemical) of meat quality (P> 0.04). However, the ratio of fat and ash in the meat of the control group has differences in indicators and is reduced by 24.81% and 0.03%, respectively. The drug had a significant effect on the biological value of meat in the experimental group, where there is a higher content of essential amino acids (P = 0.06), nonessential (P = 0.05) concentrations in comparison with the CON groups. The results obtained show that the meat of the experimental groups of sheep, when using the anthelminthic feed additive albendazole, did not have a significant effect on organoleptic parameters, but significantly positively influenced the metabolism, live weight gain and biological value of meat.
Resumo Este estudo avaliou o efeito do aditivo anti-helmíntico albendazol sobre os principais indicadores de qualidade da carne ovina obtida de animais infectados e desparasitados. Um total de 20 cabeças de carne Akzhaik e ovelhas de lã (ou seja, 2 anos de idade, de sexo diferente) foi usado em um experimento de 20 dias e dois grupos de 10 cabeças foram formados (n = 4). As ovelhas foram alimentadas com dieta básica (ou seja, controle, grupo CON), sem adicionar nada, e o segundo grupo foi alimentado com dieta básica por via oral com a adição de uma dose de 1,2 g / cabeça (um grupo experimental). Ao final do experimento, foi realizado um abate controle de cada grupo para estudar a composição bioquímica da carne e sua qualidade. O aditivo anti-helmíntico albendazol não teve efeito significativo sobre os indicadores (organolépticos e físico-químicos) de qualidade da carne (P > 0,04). No entanto, a proporção de gordura e cinzas na carne do grupo de controle tem diferenças nos indicadores e é reduzida em 24,81% e 0,03%, respectivamente. A droga teve efeito significativo sobre o valor biológico da carne no grupo experimental, onde há maior teor de aminoácidos essenciais (P = 0,06), concentrações não essenciais (P = 0,05) em comparação com os grupos CON. Os resultados obtidos mostram que a carne dos grupos experimentais de ovinos, ao utilizar o aditivo anti-helmíntico albendazol, não teve efeito significativo nos parâmetros organolépticos, mas influenciou positivamente de forma significativa no metabolismo, ganho de peso vivo e valor biológico da carne.

Abstract The aim of this study was to evaluate the convergence between the domains of the Autoquestionnaire Qualité de Vie Enfant image (AUQUEI) and the Child Perceptions Questionnaire (CPQ8-10) in the mixed dentition. A sample of 676 children aged 8 to 10 years responded to the health-related quality of life (HRQoL) and oral health-related quality of life (OHRQoL) questionnaires using the AUQUEI and the CPQ8-10, respectively. Clinical (dental caries and malocclusion) and socioeconomic variables were assessed. The validity of convergence between scores (total and per domain) of the two instruments was assessed by Spearman correlation analysis, considering that non-zero coefficient values represented a correlation between scores. The median was calculated to compare the scores of each questionnaire relative to the variables, and the nonparametric Mann-Whitney test was applied to determine statistically significant differences between the categories. A weak significant correlation (between 0.30 and 0.50) was observed between the domains and the total scores of instruments (p < 0.05), except for the leisure domain (p > 0.05). Participants with a lower family income had worse HRQoL (p < 0.05), and those with caries and malocclusion experience had worse OHRQoL (p < 0.05). In conclusion, the AUQUEI and CPQ8-10 instruments showed a weak correlation. Income and clinical variables had a negative impact on the AUQUEI and CPQ8-10, respectively.
Résumé
ABSTRACT The largest genus within the family Tabanidae (Diptera: Brachycera), Tabanus Linnaeus, has a worldwide distribution and includes medium to large conspicuous flies. Although the species are difficult to identify and a large number have already been described, several new Neotropical species have been reported for science in the past few years. Taxonomy, the science that describes and catalogs biodiversity, depends on collections, as these preserve specimens for later purposes, allowing examination and checking by specialists. In this paper we describe a new species, Tabanus argentistrigatus sp. n. based on two specimens stored in the collection of the Museum of Zoology of the São Paulo University since 1938. The new species is only known from one location in the state of Paraná, which is now highly anthropized.
Résumé
Background: Clinical supervision is pivotal in supporting nurses in rendering quality, safe patient care. Therefore, it is essential to understand clinical supervision from operational nursing managers' context to define existing challenges and propose suitable recommendations. Objectives: This study aimed to explore and describe operational nursing managers' experiences of clinical supervision within the context of an academic hospital in Gauteng province and propose evidence-based practice recommendations to improve patient safety and the quality of clinical supervision. Method: An exploratory, sequential, mixed-method design was used and implemented over two phases to take advantage of the strengths of both the qualitative and quantitative research designs. Unstructured individual interviews were conducted to collect data in phase one, and an adapted Manchester Clinical Supervision Scale (MCSS) questionnaire was used to collect data in phase two. Results: Operational nursing managers work in stressful conditions and environments with a gross shortage of staff and tools of the trade while being expected to deliver high-quality and safe nursing care. Of the sampled respondents, 36% (n = 17) were dissatisfied with the supervision they received, while 64% (n = 30) were indifferent in the sense that they did not think it was adequate or inadequate. Conclusion: Clinical supervisors should be trained and supported in clinical supervision, with regular workshops on interpersonal relations. Contribution: A clearer understanding of clinical supervision within the hospital context and evidence-based practice recommendations to improve patient safety and the quality of clinical supervision.

Uno de los principales problemas durante la dentición mixta es la determinación de la futura discrepancia entre tamaño dentario y el espacio disponible. Para predecir el ancho mesiodistal de los dientes permanentes no erupcionados se han introducido diferentes métodos de análisis. Objetivo: El propósito de este estudio fue comparar el método Tanaka-Johnston con una nueva ecuación de regresión para predecir el ancho mesiodistal de caninos y premolares permanentes no erupcionados en una población de la región de Valparaíso, Chile. Material y método: Este estudio fue realizado en la Facultad de Odontología de la Universidad de Valparaíso, desde octubre de 2022 a junio de 2023 (8 meses), la muestra estuvo compuesta por 202 modelos de estudio del departamento de ortodoncia (91 hombres y 111 mujeres) en el rango de edad de 11 -20 años. Resultados: Se demostró que el método elaborado por Lara-Sandoval presenta mayor fiabilidad respecto a las medidas mesiodistales reales de los pacientes (ICC 0,773 para maxilar y 0,762 para mandíbula), en comparación con el método de Tanaka-Johnston (ICC 0,665 para maxilar y 0,623 para mandíbula). No existen diferencias significativas entre los valores reales y el método de Lara-Sandoval. Conclusión: El método de Lara-Sandoval es mejor que el propuesto por Tanaka-Johnston para determinar el ancho mesiodistal de caninos y premolares para esta muestra. Es necesario validar este método en otras regiones del país para ser utilizado con mayor seguridad que el ya existente como método estándar nacional.
One of the main orthodontic problems in mixed dentition is the determination of future tooth and size arch discrepancy. In order to predict the mesiodistal widths of unerupted permanent teeth different methods of analyses have been introduced. The aim of this study is to compare the Tanaka-Johnston analysis with a new regressive equation to predict the mesiodistal width of unerupted permanent canines and premolars in a Chilean population sample, from Valparaíso region. This study was conducted at the Universidad de Valparaíso Dental Faculty, from october 2022 to june 2023 (8 months), and the sample comprised historical dental casts from 202 patients (91 boys and 111 girls) in the age range of 11-20 from the orthodontics department. All the patients are from the Valparaíso region, Chile. The results show that the predictions of the new regressive equation method are closer to the actual mesiodistal measurements of the patients (ICC 0,773 for maxilla and 0,762 for mandible), compared to the Tanaka- Johnston method (ICC 0,665 for maxilla and 0,623 for mandible). There are no significant differences between the real values and the Lara-Sandoval method. Lara-Sandoval method is better than the one proposed by Tanaka-Johnston to determine the mesiodistal width of canines and premolars in this sample population. It is necessary to validate this method in other regions of the country to be used with greater security than the ones that already exists as a national standard method.
Résumé
Introducción: En Cuba ha sido poco estudiado el tiempo que demora el diente, desde que aflora a la cavidad bucal hasta que alcanza el plano oclusal. Objetivo: Determinar la duración de la erupción clínica prefuncional temporal y permanente en la población de Villa Clara. Métodos: Se realizó un estudio epidemiológico descriptivo entre los años 2014 a 2018. Mediante un muestreo polietápico aleatorio simple se obtuvo una muestra de 2 584 niños y adolescentes (520 entre tres meses y cuatro años para la dentición temporal, y 2 064 entre cuatro y 14 años para la permanente), nacidos en la provincia, sin alteraciones del crecimiento general y craneofacial; se observó el brote; se calcularon por medio de la regresión de probit, las edades medias para los dientes brotados sin contacto oclusal y las que habían alcanzado la oclusión. La duración de la erupción clínica prefuncional fue calculada restando las medianas de ambas variables. Resultados: En los dientes temporales demoró más la erupción clínica prefuncional en los 1ros molares (superiores, 0,63; inferiores, 0,62); en los permanentes, en los incisivos centrales inferiores de hombres y mujeres, 1 y 1,07, respectivamente. Conclusiones: La erupción clínica prefuncional para los dientes permanentes osciló entre cuatro meses y un año; para los temporales, entre cuatro y siete meses con diferencias dentarias. Se elaboró una tabla de duración de la erupción clínica prefuncional de los dientes temporales y permanentes ajustada a la población villaclareña.
Introduction: the time the tooth takes to emerge from the oral cavity until it reaches the occlusal plane has been little studied in Cuba. Objective: to determine the duration of temporary and permanent prefunctional clinical tooth eruption in Villa Clara population. Methods: a descriptive and epidemiological study was carried out from 2014 to 2018. A sample of 2,584 children and adolescents who were born in the province without alterations in general and craniofacial growth was obtained through simple random multistage sampling (520 between three months and four years for temporary dentition and 2,064 between four and 14 years for permanent one); the outbreak was observed; the mean ages for teeth eruption without occlusal contact and those that had reached occlusion were calculated by means of probit regression. The duration of the prefunctional clinical eruption was calculated by subtracting the medians of both variables. Results: prefunctional clinical eruption took longer in temporary (upper, 0.63 and lower, 0.62) 1st molars, as well as in permanent lower central incisors of men and women (1 and 1.07, respectively). Conclusions: prefunctional clinical eruption for permanent teeth ranged from four months to one year and for temporary ones between four and seven months presenting dental differences. A table of the duration of the prefunctional clinical eruption of temporary and permanent teeth was created according to Villa Clara population.

Tradicionalmente la investigación se ha dividido según su metodología en cuantitativa y cualitativa. La metodología mixta de investigación, que combina ambos métodos, se ha consolidado como una tercera vía, permitiendo abordar de forma integral problemas de investigación de alta complejidad. Aunque existen diversas definiciones sobre la investigación con métodos mixtos, todas ellas comparten aspectos como la recolección y análisis de datos tanto cuantitativos como cualitativos, y la interpretación integrada de los resultados dentro de una misma investigación. Este tipo de investigación es una herramienta importante para abordar la complejidad propia del campo de la salud, permitiendo comprender e integrar los datos cuantitativos con aspectos vivenciales y experienciales. Con ello se logra una perspectiva amplia y profunda de los problemas de salud, dando respuesta a las políticas y servicios sanitarios. Durante el desarrollo de una investigación con métodos mixtos, existen etapas clave donde ambos enfoques pueden integrarse dependiendo de los objetivos planteados por los equipos de investigación. Aunque los estudios con métodos mixtos pueden ser muy diferentes, se han identificado modelos generales que guían el desarrollo de un diseño específico a utilizar. Estos modelos se clasifican según la prioridad de cada enfoque, la secuencia en la que se ejecutará cada enfoque, el nivel y momento de integración de los datos y el propósito de esta integración para el estudio en particular.
Traditionally, research has been divided according to its methodology into quantitative and qualitative. Mixed research methodology combines both methods and has established itself as a third approach, allowing to comprehensively address high-complexity research problems. Although there are various definitions of mixed methods research, they all share aspects such as the collection and analysis of both quantitative and qualitative data and the integrated interpretation of the results within the same research. This type of research is an important tool to address the complexity of health sciences, allowing the understanding and integration of quantitative data with experience-based aspects. In this way, a broad and deep perspective of health problems is achieved, providing a solution to sanitary policies and services. During the development of mixed methods research, there are key stages where both approaches can be integrated depending on the objectives set by the investigators. Although mixed methods studies may differ widely, general models have been identified to guide the development of a single specific design. These models are classified according to the priority of each approach, the sequence in which each approach will be executed, the level and timing of data integration, and the purpose of integrating the data for the study.
Résumé
Abstract Objectives: To review and provide evidence-based recommendations for the diagnosis and treatment of otosclerosis. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on otosclerosis were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. Results: The topics were divided into 2 parts: 1) Diagnosis - audiologic and radiologic; 2) Treatment - hearing AIDS, pharmacological therapy, stapes surgery, and implantable devices - bone-anchored devices, active middle ear implants, and Cochlear Implants (CI). Conclusions: The pathophysiology of otosclerosis has not yet been fully elucidated, but environmental factors and unidentified genes are likely to play a significant role in it. Women with otosclerosis are not at increased risk of worsening clinical condition due to the use of contraceptives or during pregnancy. Drug treatment has shown little benefit. If the patient does not want to undergo stapedotomy, the use of hearing aids is well indicated. Implantable systems should be indicated only in rare cases, and the CI should be indicated in cases of profound deafness.

Purpose: Our study was designed to determine ophthalmologists’ dexterity in performing standard ophthalmic procedures at various levels of expertise via a structured questionnaire. Methods: A structured questionnaire was administered via the Google platform from August 20 to September 19, 2022, to assess the perspectives and preferences of ophthalmologists concerning their proficiency in using their right hand, left hand, or both hands to perform routine tasks required in the practice of ophthalmic medicine and surgery. Results: Two hundred and three participants took part in the survey. A majority (n = 162, 79.8%) of the clinicians considered themselves right?handed, nine (4.4%) considered themselves left?handed, and 32 (15.7%) considered themselves ambidextrous. Also, 86% (n = 174) of the participants considered ambidexterity an essential trait in the practice of ophthalmic medicine and surgery. The number of cataract surgeries performed had an impact on the comfort of using both hands for performing anterior vitrectomy (P < 0.001), injection of viscoelastic (P < 0.001), and toric marking (P < 0.05), but not on the performance of capsulorhexis and switching of foot pedals. The number of procedures carried out had an impact on the comfort of using both hands in gonioscopy (P < 0.001), 90 D evaluation (P < 0.001), and 20 D evaluation (P < 0.05). More years of experience had an impact on skills involving the use of both hands for slit lamp joystick usage (P < 0.05) and laser procedures (P < 0.001). Conclusion: Irrespective of a person’s handedness, trained ambidexterity in the required fields is achievable and has a significant impact on one’s ability to perform the required skill optimally and appropriately.
Résumé
The characteristics of two cyanobacterial strains, Anabaena oryzae and Nostoc muscorum, were studied in order to use them as biofertilizers in a field experiment conducted in the two winter seasons of 2021 and 2022 at the Ismailia Agricultural Research Center Station to study the effect of both strains on peanut plant in sandy soil. Cyanobacterial strains were used individually by coating seed, soil drench, and foliar applications, as well as mixed applications of two strains in various ways. Both cyanobacterial strains morphological examination revealed that they both have heterocysts, nitrogen, phosphorus, and potassium in their culture filtrate, and they were able to produce chlorophyll a and phosphatase enzymes. The results of an agricultural experiment showed that using Nostoc muscorum and Anabaena oryzae separately had a positive effect on peanut plants in a variety of applications, but combining both of these applications with 75% nitrogen increased the growth traits, nutrient contents, and soil biological activities in both peanut plants and their rhizosphere soil. The soil drench treatment with A. oryzae and Nostoc muscorum plus 75% nitrogen produced the highest growth results and peanut yields in a single application. The A. oryzae Soil Drench Application (S) + N. muscorum Foliar Application (F) with 75% N reported the best outcomes in mixed treatments. However, compared to single applications, all blended applications displayed better growth and yield characteristics. The results of the study suggest that employing cyanobacteria in a mixed application will enhance its advantages over a single use.

Introducción: El análisis más utilizado por los ortodoncistas para predecir el espacio ideal del canino y premolares es el Gold Standard de Tanaka-Johnston. Sin embargo, la utilización de este análisis en otros grupos poblacionales a nivel mundial puede ser cuestionable. Objetivo: Predecir el espacio ideal para la erupción del canino y premolares utilizando el análisis de Tanaka y Johnston y el de Ramos, et al. Material y métodos: Fue un estudio descriptivo. Se utilizaron 110 pares de modelos de estudio con dentición permanente, recolectados durante 2018 y 2019. Los anchos mesiodistales fueron medidos con un vernier digital marca UBERMANN® con una precisión de ± 0,01 mm. A los datos obtenidos se les realizó estadística no paramétrica mediante la prueba de comparación de Kruskal-Wallis. Resultados: El análisis de Tanaka-Johnston mostró una diferencia entre los valores predictivos y reales de -0,50 mm (±1,68) con una diferencia estadística de p=0,0001 y el análisis de Ramos, et al., fue de -0,35 mm (±1,70) con una diferencia estadística de p=0,0001. Conclusiones: Se subestimó el espació ideal para la erupción del canino y premolares con el análisis de Tanaka-Johnston y el análisis validado por Ramos, et al. Sin embargo, el análisis de Ramos, et al., se acercó más a los diámetros mesiodistales reales del canino y premolares.
Introduction: The analysis most commonly used by orthodontists to predict the ideal space of the canine and premolars is the Tanaka-Johnston Gold Standard. However, the use of this analysis in other population groups worldwide may be questionable. Objective: To predict the ideal space for the eruption of the canine and premolars using the Tanaka-Johnston analysis and that of Ramos, et al. Material and Methods: A descriptive study was carried out using 110 pairs of study models with permanent dentition, collected during the period from 2018 to 2019. The mesiodistal widths were measured with a UBERMANN® digital vernier with an accuracy of ± 0.01 mm. Non-parametric statistics were performed on the data obtained using the Kruskal-Wallis comparison test. Results: The Tanaka-Johnston analysis showed a difference between the predictive and real values of -0.50 mm (±1.68) with a statistical difference of p=0.0001, and the Ramos et al. analysis was of -0.35 mm (±1.70) with a statistical difference of p=0.0001. Conclusions: The ideal space for the eruption of the canine and premolars was underestimated with the Tanaka-Johnston analysis and the analysis validated by Ramos, et al. However, the Ramos, et al. analysis was closer to the actual mesiodistal diameters of the canine and premolars.
Résumé
El carcinosarcoma primario ovárico es una neoplasia de baja incidencia, que suele ser diagnosticado en estadios avanzados y cursa con un mal pronóstico. Se comunica el caso de una paciente de 64 años con una tumoración abdominopélvica de 15 cm. El examen histológico evidenció una neoplasia maligna bifásica ovárica asociada a un carcinoma seroso intraepitelial tubárico, hallazgo que estaría en relación con la patogénesis de esta neoplasia.
Primary ovarian carcinosarcoma is a low incidence neoplasm that is usually diagnosed in advanced stages and has a poor prognosis. We report the case of a 64-yearold female patient with a 15 cm abdominopelvic tumor. Histological examination revealed a malignant ovarian biphasic malignancy associated with a serous tubal intraepithelial carcinoma, a finding that would be related to the pathogenesis of this neoplasm.

Objetivo: estudiar y comparar la inclinación de la cabeza entre niños con dentición primaria completa y dentición mixta primera fase. Materiales y métodos: el estudio incluyó a 80 voluntarios entre 4 y 9 años, a quienes se les tomó una fotografía facial de perfil derecho estandarizada, en Posición Natural de Cabeza. Éstas fueron analizadas mediante software de edición de imágenes para determinar la inclinación de la cabeza de cada voluntario. Para ello, se definió un plano (plano t-ex) formado por el punto Intertrágico (t) y Exocanto (ex) y se comparó respecto a la horizontal verdadera. Los datos obtenidos fueron tabulados, clasificados en dos grupos según el tipo de dentición y analizados estadísticamente. Resultados: el promedio de inclinación del plano t-ex fue de 22,7º en el grupo de niños con dentición primaria completa y de 25,8º en el grupo de niños con dentición mixta primera fase. La diferencia entre ambos grupos fue de 3,1º, con significancia estadística (p = 0,006). Conclusión: la inclinación de la cabeza de los niños con dentición mixta primera fase es mayor en sentido antihorario, respecto a la de los niños con dentición primaria completa.
Objective: to study and compare head tilt among children with complete primary dentition and first transitional period of the mixed dentition stage. Materials and methods: the study included 80 volunteers between 4 and 9 years of age, who were taken a standardized right profile facial photograph in a Natural Head Position. These photographs were analyzed using image editing software to determine the head tilt of each volunteer. For this, a plane (plane t-ex) formed by the Intertragic point (t) and Exocanth (ex) was defined and compared with respect to the true horizontal. The data obtained were tabulated, classified into two groups according to the type of dentition and statistically analyzed. Results: the average t-ex plane inclination was 22.7º in the group of children with complete primary dentition and 25.8º in the group of children with first transitional period of the mixed dentition stage. The difference between both groups was 3.1º, with statistical significance (p = 0.006). Conclusion: the head tilt of children with first transitional period of the mixed dentition stage is greater in an anti-clockwise direction, compared to that of children with complete primary dentition.
Résumé
Background: In 1972, Dr Sharp and colleagues described a new connective tissue disease, characterized by overlapping features of systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and polymyositis/ dermatomyositis (PM/DM) and by the presence of antibodies against the U1 small nuclear ribonucleoprotein autoantigen (U1 snRNP). This condition was termed mixed connective tissue disease (MCTD) and proposed as a distinct disease. Later, after observing the clinical evolution of MCTD patients, Sharp himself agreed that the original concept of MCTD had to be modified and that Internal organs were at risk for serious complications; patients were not always steroid responsive; prognosis was not always benign. Materials and methods: Patients in the age group of 15-50 years diagnosed to have connective tissue diseases were included. 8 patients in the age group of 15-50 admitted in Medicine department were taken and they were evaluated for the clinical profile of sharp syndrome by thorough clinical examination, routine laboratory tests and special investigations depending on the clinical profile. Results: 8 patients with connective tissue disease attending the medicine OPD were studied. Of these 8 patients were female patients. The median age of onset was 36 years, 8 patients met criteria by sharp and Alarcon-Segovia. The clinical features of patients at presentation are Raynaud抯 phenomena, Puffy fingers, esophagus dysmotility, skin rash, interstitial lung disease, arthritis, pulmonary hypertension, myositis, anemia. Conclusion: SHARP syndrome is a rare condition, as evidenced by the small series of cases reported to date. Diagnosis is based on clinical and paraclinical criteria. The evolution can be interspersed with various complications that can affect the short, medium and long-term prognosis
Résumé
Introducción: las interferencias oclusales no controladas precozmente pueden producir desviación de la mandíbula en sentido anteroposterior o transversal. El manejo de las mordidas cruzadas se debe iniciar en el momento del diagnóstico, preferiblemente en edades tempranas, con el fin de tratarlas en el nivel primario de prevención. Objetivo: determinar el comportamiento de la maloclusión funcional causada por interferencias oclusales en niños con dentición mixta de la Escuela Primaria Mártires del Corynthia, entre octubre de 2019 y junio de 2021. Materiales y métodos: se realizó un estudio observacional descriptivo de corte transversal en la Escuela Primaria Mártires del Corynthia, del Área de Salud José Jacinto Milanés, del municipio de Matanzas, entre octubre de 2019 y junio de 2021. El universo estuvo conformado por 66 niños. Se utilizó una planilla de recolección de datos y se solicitó el consentimiento informado a los tutores de los niños. Resultados: las edades donde los niños presentaron mayor afectación fueron de 6 a 7 años y de 8 a 9 años, ambos rangos con un 10,6 %. El 27,3 % presentó interferencias oclusales y mordida cruzada posterior unilateral. El 48,5 % fue del sexo femenino y el 30,3 % tenían edades de 6 a 7 años. El 71,2 % eran simétricos y presentaron mordida cruzada posterior unilateral. Los simétricos y con línea media coincidente representaron un 36,4 %. Conclusiones: la maloclusión funcional más frecuente en niños con dentición mixta fue la mordida cruzada posterior unilateral, que se relacionó de manera directa con las interferencias oclusales. Las asimetrías faciales y la línea media desviada estuvieron asociadas a dicha maloclusión.
Introduction: early uncontrolled occlusal interferences can produce anterior-posterior jaw deflection. Management of cross-bites should be initiated at the time of diagnosis, preferably at early ages, in order to treat them at the primary level of prevention. Objective: to determine the behavior of functional malocclusion caused by occlusal interferences in children with mixed dentition from the Martires del Corynthia primary school between October 2019 and June 2021. Materials and methods: a cross-sectional, observational, descriptive study was carried out at the Martires del Corynthia Primary School, of the Jose Jacinto Milanes Health Area, Matanzas municipality, between October 2019 and June 2021. The universe consisted of 66 children. A data collection form was used and informed consent was requested from the children's guardians. Results: the ages where the children presented more affectation were from 6 to 7 years and from 8 to 9 years, both ranges with 10.6%. 27.3% presented occlusal interferences and posterior unilateral cross-bite. 48.5% were female and 30.3% were 6 to 7 years old. 71.2% were symmetrical and presented unilateral posterior cross-bite. Symmetric patients and with a coincident midline represented 36.4%. Conclusions: the most frequent functional malocclusion in children with mixed dentition was the unilateral posterior cross-bite, which was related to occlusal interferences in a direct way. Facial asymmetries and a deviated midline were associated with the before mentioned malocclusion.
Résumé
Background: AES is responsible for causing high social and economic burden to the affected families. The study was conducted to know the household characteristics, cost of illness and coping strategy adopted by the family members of AES children admitted to a tertiary care facility in Assam, India. Methods: It was a sequential exploratory mixed method study, with a cross-sectional survey among AES chil-dren and their guardians, followed by In Depth interview. Results: Out of 51 cases 55% were male. The median age was 11 years. 53% of the families belonged to lower socioeconomic class. 96% of families reported to reside in rural areas. Commonly reported household assets were mobile phone 94%, bicycle 86%, television 31% and motorcycle 29%. Three major themes were emerged to contribute towards economic burden. The first major theme is “Direct cost” due to patient trans-portation cost (mean Rs 1161.00) and hospital costs: mostly due to medicinal cost (mean Rs1955.00), investi-gational cost (mean Rs 2920.00) and food cost (mean Rs 8375.00). The second theme “Indirect cost” is due to work days loss: 100% care providers had missed work days during hospital stay of their children and 84% had missed work days during post hospital care. The third theme is “Inherent cost spotted through coping mechanisms” which mostly 94% included borrowing money from the market and 31.4% selling household assets. Conclusion: Cost of illness is a huge burden to the AES afflicted families which demands reforms in health care financing and reimbursement in current context.
