Executive Functions and Theory of Mind in Teachers and Non-Teachers.

Human teaching is a key behavior for the socialization of cultural knowledge. Previous studies suggest that human teaching behavior would support the development of executive and ToM skills, which in turn would refine the teaching behavior. Given this connection, it raises the question of whether subjects with professional training in teaching also have more efficient executive and ToM systems. To shed light on this issue, in the present study we compared the performance of professional teachers (N = 20, age range = 35-61 years) with a matched control group of non-teachers (N = 20, age range: 29-64 years) on tasks measuring working memory (Sternberg Task), cognitive flexibility (Wisconsin Card Sorting Test), executive control (Attention Network Test), along with online ToM skills (Frith-Happé Animations Task), emotion recognition (Reading the Mind in the Eyes Test) and first-order and second-order ToM (Yoni Task). We found that teachers were significantly more accurate on tasks involving cognitive flexibility (p = .014) and working memory (p = .040), and more efficient on tasks requiring executive control of attention (p = .046), compared to non-teachers. In ToM tasks, differences in accuracy between teachers and non-teachers were not found. But, teachers were slower to respond than non-teachers (about 2 s difference) on tasks involving emotion recognition (p = .0007) and the use of second-order affective ToM (p = .006). Collectively, our findings raise an interesting link between professional teaching and the development of cognitive skills critical for decision-making in challenging social contexts such as the classroom. Future research could explore ways to foster teachers' strengths in cognitive flexibility, working memory, and executive control of attention to enhance teaching strategies and student learning outcomes. Additionally, exploring factors behind slower response times in affective ToM tasks can guide teacher-training programs focused on interpersonal skills and improve teacher-student interactions.

Assessing Spatial User Experience for Design Guidelines: A Comparative Study of Outpatient Waiting Rooms With Conventional Versus Modern Features.

OBJECTIVES: Identify waiting room design features that are most appreciated by outpatients and their companions in conventional and modern waiting rooms. Evaluate if end users evaluate the environment differently from experts and in what aspects. Provide evidence-based design guidelines that orient designers and healthcare managers. BACKGROUND: Built environments are relevant in patients' evaluation of overall healthcare service. For outpatients, waiting frequently consumes the largest amount of time; thus, waiting room interior design has great potential to enhance their experience. METHODS: This study compares perceptions of two types of waiting rooms-conventional and modern-based on the spatial user experience (SUE) model. In the first stage of the study, we compared user evaluations of conventional waiting rooms (n = 137) and modern waiting rooms (n = 426) with respect to the eight SUE model dimensions using multigroup structural equation modeling. In the second stage, an expert ergonomist and two professional interior designers assessed both types of waiting rooms. RESULTS: Results showed that modern waiting rooms were perceived to be significantly better in all SUE dimensions. We also found experts' evaluations were overall consistent with users' perceptions. Discrepancies were only found in temperature perception, signage evaluation, and spatial appreciation. CONCLUSIONS: Participants valued modern style waiting room features such as good quality signage, use of armchairs and sofas, a controlled environment, and decoration. We suggest involving end users in the design process to respond to their needs and promote a positive experience. Finally, we provide easy-to-adopt design guidelines to improve patients' waiting room experience.

Pronación precoz en pacientes con síndrome de distrés respiratorio por neumonía COVID-19 / Early pronation in patients with respiratory distress due to COVID-19 pneumonia

Introducción: El tratamiento de los pacientes con insuficiencia respiratoria en el curso de la COVID-19 ha sido un reto en todo el mundo, debido al gran número de pacientes afectados por la agresividad del virus, el empleo de los recursos humanos y la disponibilidad de los equipos. Objetivo: Demostrar la utilidad de la pronación precoz para lograr mejoría de la oxigenación y prevenir en muchos casos la intubación endotraqueal en pacientes con distrés respiratorio por la COVID-19. Métodos: Se realizó un estudio observacional analítico, de corte transversal retrospectivo, de pacientes que ingresaron en la Unidad de Cuidados Intensivos del Hospital Cubano En Qatar, perteneciente a la Hamad Medical Corporation, en el período comprendido de marzo a mayo de 2021. Se utilizaron variables enfocadas en demostrar la respuesta ventilatoria. Se utilizó el paquete estadístico Statistical Package Social Science (Ssps) versión 21.0, según porcentaje y Chi cuadrado, y la t de Student para análisis estadístico deductivo de las muestras relacionadas. Resultados: Predominó el grupo de edades de 3-50 años en pacientes con 2 o más comorbilidades. La oxigenación con HFNC y combinada con NIV fueron las más empleadas. La mayoría de las variables en prueba de muestras relacionadas fueron altamente significativas. Conclusiones: La pronación precoz, como complemento del tratamiento intensivo en pacientes con insuficiencia respiratoria, causada por la enfermedad COVID-19, proporciona una mejor recuperación de los enfermos y una mejoría indiscutibles de los parámetros de ventilación y oxigenación(AU)

Introduction: In the course of COVID-19, the management of patients with respiratory failure has been a challenge worldwide, due to the large number of patients affected by the aggressiveness of the virus, the use of human resources and the availability of equipment. Objective: To show the usefulness of early pronation for improving oxygenation and prevent, in many cases, endotracheal intubation in patients with respiratory failure due to COVID-19. Methods: An analytical, observational, retrospective and cross-sectional study was carried out with patients hospitalized in the intensive care unit of the Cuban Hospital in Qatar, belonging to the Hamad Medical Corporation, in the period from March to May 2021. Variables focused on demonstrating the ventilatory response were used. The Statistical Package Social Science (SPSS), version 21.0, was used, according to percentage and chi-square, as well as Student's t-test for deductive statistical analysis of related samples. Results: The predominant age group was 3-50 years, in patients with two or more comorbidities. Oxygenation with high-flow nasal cannula and combined with non-invasive ventilation were the most widely used. Most of the variables in the related samples test were highly significant. Conclusions: Early pronation, as an adjunct to intensive management of patients with respiratory failure caused by COVID-19, provides better recovery for patients and an indisputable improvement of ventilation and oxygenation parameters(AU)

Tasa de fecundidad infantil y la paulatina no declaración de los progenitores en Costa Rica (2000-2019) / Infant fertility rate and the gradual non-declaration of parents in Costa Rica (2000-2019)

Resumen Introducción: la maternidad infantil debe evidenciarse por su propia naturalización social como producto de violaciones. Es relevante su estudio luego de aprobadas algunas leyes que buscan evitarla. Objetivo: analizar el comportamiento de la tasa de fecundidad en niñas entre 10 y 14 años en Costa Rica (2000-2019) y la edad de los perpetradores o «padres» en el marco de los aparatos ideológicos de Estado, desigualdad social y dentro de un contexto social conservador. Método: la información se extrajo de las bases de datos en línea del Instituto Nacional de Estadística y Censos. El abordaje es cuantitativo, con un estudio correlacional y no experimental de la población descrita en todo el país y en áreas geográficas pequeñas. Resultados: la fecundidad infantil ha disminuido entre los años 2000 y 2019. La edad estimada de embarazo es cuando se cumplen los 13 años. Se detectaron áreas geográficas con mayores niveles de fecundidad dentro y fuera del Gran Área Metropolitana. Se evidenció estadísticamente que algunas leyes han contribuido al aumento considerable de perpetradores no declarados luego de 2016. Todo esto fue validado por instituciones religiosas y los medios de comunicación lo pregonaron como positivo, a pesar de la jurisprudencia nacional e internacional. Conclusiones: esta información es trascendental para orientar las políticas públicas educativas y de salud desde el primer nivel de atención, con miras a promover los derechos reproductivos de las niñas.

Abstract Introduction: Child motherhood must be evidenced by the naturalization of this social fact itself, since it is the product of rape. The study of this phenomenon is relevant after the approval of some laws that seek to prevent it. Objective: to analyze of the fertility rate in girls between the ages 10 and 14 in Costa Rica (2000-2019) the age of the perpetrators or "parents" within the framework of ideological State apparatuses, social inequality, and a conservative social context. Method: The information was processed from the online databases of the Instituto Nacional de Estadística y Censos. The approach is quantitative, with a correlational and non-experimental study of the population of girls between 10 and 14 years of age throughout the country, as well as for small geographic areas. Results: Infant fertility has decreased between 2000 and 2019. The estimated age of pregnancy is at the age of 13. Geographical areas with higher fertility levels are detected, inside and outside the Metropolitan Area. It is statistically evidenced that these have contributed to the increase in undeclared perpetrators considerably after 2016. All this is validated by religious institutions and the media proclaim as positive, despite national and international jurisprudence. Conclusions: This information is essential to guide public educational and health promotion policies from the first level of care, which promote the reproductive rights of girls.

Increase in Beta Power Reflects Attentional Top-Down Modulation After Psychosocial Stress Induction.

Selective attention depends on goal-directed and stimulus-driven modulatory factors, each relayed by different brain rhythms. Under certain circumstances, stress-related states can change the balance between goal-directed and stimulus-driven factors. However, the neuronal mechanisms underlying these changes remain unclear. In this study, we explored how psychosocial stress can modulate brain rhythms during an attentional task and a task-free period. We recorded the EEG and ECG activity of 42 healthy participants subjected to either the Trier Social Stress Test (TSST), a controlled procedure to induce stress, or a comparable control protocol (same physical and cognitive effort but without the stress component), flanked by an attentional task, a 90 s of task-free period and a state of anxiety questionnaire. We observed that psychosocial stress induced an increase in heart rate (HR), self-reported anxiety, and alpha power synchronization. Also, psychosocial stress evoked a relative beta power increase during correct trials of the attentional task, which correlates positively with anxiety and heart rate increase, and inversely with attentional accuracy. These results suggest that psychosocial stress affects performance by redirecting attentional resources toward internal threat-related thoughts. An increment of endogenous top-down modulation reflected an increased beta-band activity that may serve as a compensatory mechanism to redirect attentional resources toward the ongoing task. The data obtained here may contribute to designing new ways of clinical management of the human stress response in the future and could help to minimize the damaging effects of persistent stressful experiences.

Bi-Stable Perception: Self-Coordinating Brain Regions to Make-Up the Mind.

Bi-stable perception is a strong instance of cognitive self-organization, providing a research model for how 'the brain makes up its mind.' The complexity of perceptual bistability prevents a simple attribution of functions to areas, because many cognitive processes, recruiting multiple brain regions, are simultaneously involved. The functional magnetic resonance imaging (fMRI) evidence suggests the activation of a large network of distant brain areas. Concurrently, electroencephalographic and magnetoencephalographic (MEEG) literature shows sub second oscillatory activity and phase synchrony on several frequency bands. Strongly represented are beta and gamma bands, often associated with neural/cognitive integration processes. The spatial extension and short duration of brain activities suggests the need for a fast, large-scale neural coordination mechanism. To address the range of temporo-spatial scales involved, we systematize the current knowledge from mathematical models, cognitive sciences and neuroscience at large, from single-cell- to system-level research, including evidence from human and non-human primates. Surprisingly, despite evidence spanning through different organization levels, models, and experimental approaches, the scarcity of integrative studies is evident. In a final section of the review we dwell on the reasons behind such scarcity and on the need of integration in order to achieve a real understanding of the complexities underlying bi-stable perception processes.

Surgical Stabilization of Rib Fractures: Indications, Techniques, and Pitfalls.

Rib fractures are a common thoracic injury that is encountered in 20% to 39% of patients with blunt chest trauma and is associated with substantial morbidity and mortality1,2. Traditionally, the majority of patient with rib fractures have been managed nonoperatively. Recently, the utilization of surgical stabilization of rib fractures has increased considerably because the procedure has shown improved outcomes3-5. DESCRIPTION: Surgical stabilization should be considered in cases of multiple bicortically displaced rib fractures, especially in those with a flail chest and/or a concomitant ipsilateral displaced midshaft clavicular fracture or sternal fracture, as such cases may result in thoracic wall instability. For surgical stabilization of rib fractures, we classify rib fractures by location, type of fracture, and degree of displacement after obtaining thin-sliced chest computed tomography (CT) scans. The incision is selected depending on the fracture location, and the surgical technique is chosen relevant to the type of fracture. Single-lung intubation is preferred if there is no severe contralateral pulmonary contusion. We favor performing video-assisted thoracoscopy if possible to control bleeding, evacuate hematomas, repair a lung, and perform cryoablation of the intercostal nerves. A lateral approach is considered to be the main surgical approach because it allows access to the majority of rib fractures. A curvilinear skin incision is made overlying the fractured ribs. Posterior rib fractures are exposed through a vertical incision within the triangle of auscultation, and anterior fractures, through a transverse inframammary incision. The muscle-sparing technique, splitting alongside fibers without transection, should be utilized if possible and supplemented by muscle retraction. For surgical stabilization of rib fractures, we currently prefer precontoured side and rib-specific plates with threaded holes and self-tapping locking screws. Polymer cable cerclage is used to enhance plating of longitudinal fractures, rib fractures near the spine, osteoporotic ribs, and injuries of rib cartilage. The third to eighth ribs are plated most often. Intercostal muscle deficit, if present, is repaired with a xenograft patch. In comminuted rib fractures, the bone gap is bridged with bone graft. Surgical stabilization of rib fractures is recommended within the first 7 days after trauma, preferably within the first 3 days6-8. ALTERNATIVES: Nonoperative treatment alternatives include (1) epidural analgesia when not contraindicated because of anticoagulant venous thromboembolism prophylaxis9,10; (2) thoracic paravertebral blockage, e.g., serratus anterior or erector spinae plane nerve block11,12; (3) intercostal nerve block; (4) intravenous or enteral analgesics, e.g., opioids, acetaminophen, and nonsteroidal anti-inflammatory drugs (NSAIDs); (5) intrapleural analgesia, e.g., bupivacaine infusion; and (6) multimodal analgesia that incorporates regional techniques, systemic analgesics, and analgesic adjuncts9. RATIONALE: Surgical stabilization of rib fractures is a safe and effective method to treat displaced rib fractures. The procedure provides definitive stabilization of fractures, improves pulmonary function, lessens pain medication requirements, prevents deformity formation, and results in reduced morbidity and mortality.

Brain-to-Brain Coupling in the Gamma-Band as a Marker of Shared Intentionality.

Cooperation and competition are two ways of social interaction keys to life in society. Recent EEG-based hyperscanning studies reveal that cooperative and competitive interactions induce an increase in interbrain coupling. However, whether this interbrain coupling effect is just a reflection of inter-subject motor coordination or can also signal the type of social interaction is unknown. Here, we show that behavioral coordination and social interaction type can be distinguished according to the frequency of oscillation in which the brains are coupled. We use EEG to simultaneously measure the brain activity of pairs of subjects, while they were performing a visual cue-target task in a cooperative and competitive manner. Behavioral responses were quasi-simultaneous between subject pairs for both competitive and cooperative conditions, with faster average response times for the competitive condition. Concerning brain activity, we found increased interbrain coupling in theta band (3-7 Hz) during cooperation and competition, with stronger coupling during competitive interactions. This increase of interbrain theta coupling correlated with a decrease in reaction times of the dyads. Interestingly, we also found an increase in brain-to-brain coupling in gamma band (38-42 Hz) only during cooperative interactions. Unlike the theta coupling effect, the gamma interbrain coupling did not correlate with dyads' reaction times. Taken together, these results suggest that theta interbrain coupling could be linked to motor coordination processes common to cooperative and competitive interactions, while gamma brain-to-brain coupling emerges as an electrophysiological marker of shared intentionality during cooperative interactions.

Synthesis of thieno[2,3-h]-/[3,2-h]quinolines and thieno[2,3-f] quinolines by Brønsted acid mediated cycloisomerisation.

Several thieno[2,3-h]-/[3,2-h]- and [2,3-f]quinolines have been synthesised from 2,3-dihalogenated pyridines or -quinolines by site-selective Pd catalysed cross-coupling reactions and Brønsted acid mediated cycloisomerisations as the final key step. This newly developed synthetic strategy is used in a modular way to synthesize diverse regioisomeric derivatives, tolerates various functional groups, and proceeds with high selectivity, and the desired final products have been isolated in high overall yields.

Humor Improves Women's but Impairs Men's Iowa Gambling Task Performance.

The Iowa Gambling Task (IGT) is a popular method for examining real-life decision-making. Research has shown gender related differences in performance, in that men consistently outperform women. It has been suggested that these performance differences are related to decreased emotional control in women compared to men. Given the likely role of emotion in these gender differences, in the present study, we examine the effect of a humor induction on IGT performance and whether the effect of humor is moderated by gender. IGT performance and parameters from the Expectancy Valence Model (EVM) were measured in 68 university students (34 men; mean age 22.02, SD = 4.3 and 34 women; mean age 22.3, SD = 4.1) during a 100 trial-IGT task. Participants were exposed to a brief video before each of the IGT decisions available; one half of the samples (17 men and 17 women) was exposed to 100 humor videos, while the other half was exposed to 100 non-humor videos during the task. We observed a significant interaction between gender and humor, such that under humor, women's performance during the last block (trials 80-100) improved (compared to women under non-humor), whereas men's performance during the last block was worse (compared to men under non-humor). Consistent with previous work, under non-humor, men outperformed women in the last block. Lastly, our EVM results show that humor impacts the learning mechanisms of decision-making differently in men and women. Humor impaired men's ability to acquire knowledge about the payoff structure of the decks, and as a consequence, they were stuck in suboptimal performance. On the other hand, humor facilitated women's ability to explore and to learn from experience, improving performance. These findings deepen our understanding of the mechanisms underlying IGT decision-making and differential effects of humor in men and women.

ABSTRACT Background: bone tumors are sometimes difficult to diagnose, they are divided into benign and malignant, benign tumors are the most frequent and among them the Osteochondroma is the main one. The malignant ones in spite of their low frequency are important for their high mortality, which varies between 80 to 95%, and the serious physical and emotional consequences that their treatment brings to patients. The most common malignant bone tumor types are Ewing's sarcoma and osteogenic sarcoma. Objective: to deepen the knowledge of bone tumors in pediatric age. Methods: the search of the information was made in a period of five months (from August 1st, 2017 to December 31st, 2017) and the following key words were used: bone neoplasms and Childhood, from the information obtained a bibliographical review of a total of 246 articles published in PubMed, Hinari, Medline, and SciELO databases was made through the EndNote search manager and reference manager, of which 50 selected citations were used to perform the review, 40 of them from the last five years, where two books were included. Results: forms of clinical presentation of bone tumors and imaging, laboratory and histological studies are addressed. Both conservative and surgical treatment modalities are described. Conclusions: benign osseous tumors in the pediatric age are more frequent and osteochondroma predominates in them and malignant tumors include Ewing tumor and osteogenic sarcoma.

Beta Oscillations Distinguish Between Two Forms of Mental Imagery While Gamma and Theta Activity Reflects Auditory Attention.

Visual sensory processing of external events decreases when attention is internally oriented toward self-generated thoughts and also differences in attenuation have been shown depending on the thought's modality (visual or auditory thought). The present study aims to assess whether such modulations occurs also in auditory modality. In order to investigate auditory sensory modulations, we compared a passive listening condition with two conditions in which attention was internally oriented as a part of a task; a visual imagery condition and an inner speech condition. EEG signal was recorded from 20 participants while they were exposed to auditory probes during these three conditions. ERP results showed no differences in N1 auditory response comparing the three conditions reflecting maintenance of evoked electrophysiological reactivity for auditory modality. Nonetheless, time-frequency analyses showed that gamma and theta power in frontal regions was higher for passive listening than for internal attentional conditions. Specifically, the reduced amplitude in early gamma and theta band during both inward attention conditions may reflect reduced conscious attention of the current auditory stimulation. Finally, different pattern of beta band activity was observed only during visual imagery which can reflect cross-modal integration between visual and auditory modalities and it can distinguish this form of mental imagery from the inner speech. Taken together, these results showed that attentional suppression mechanisms in auditory modality are different from visual modality during mental imagery processes. Our results about oscillatory activity also confirm the important role of gamma oscillations in auditory processing and the differential neural dynamics underlying the visual and auditory/verbal imagery.

ABSTRACT Background: benign bone tumors are the most frequent in the pediatric age, among them; the Osteochondroma is the main one. Objective: to present a case of Osteochondroma of the foot that it was diagnosed in the outpatient clinic by means of the clinical symptoms and radiographs. Clinical case: 10-years-old female white patient. The mother says that the girl reported pain when wearing a shoe and she noticed an increase in volume when touching the anterior part of the foot, for which she was brought to the outpatient clinic where a physical examination revealed a hard, non-movable mass in the distal region of the second metatarsal. Radiography of the anteroposterior and lateral foot was indicated and when an increase in volume was observed in the distal region of the second metatarsal, it was decided to enter with the diagnosis of Osteochondroma, for surgical treatment by means of bone resection and biopsy. Conclusions: Osteochondroma of the foot is considered a rare diagnosis in our environment, the treatment of choice is surgery to improve clinical manifestations.

Extracellular Matrix Applications in the Treatment of Open Fractures With Complex Wounds and Large Soft Tissue Defects.

Use of biologic scaffolds such as extracellular matrix (ECM) is a promising trend in the treatment of complex wounds in orthopedic trauma patients. In this clinical series we describe the technique of the successful application of porcine urinary bladder ECM products in the treatment of open fractures of the extremities with complex wounds and large soft tissue defects. The clinical outcomes demonstrated that even in challenging cases where local flap coverage of bone or neurovascular structures is not possible, sequential xenograft implantation allowed us to achieve a stable soft tissue envelope. Different forms of ECM products are easy to apply in the presence of orthopedic hardware. In certain wounds, complete closure can be achieved even without subsequent skin grafting. We recommend relatively earlier application of xenograft.

Vocalization-Silence Dynamic Patterns: A system for measuring coordination in psychotherapeutic dyadic conversations / Patrones Dinámicos de Vocalización-Silencio: un sistema para medir coordinación en conversaciones diádicas en psicoterapia

Abstract This paper presents the Vocalization-Silence Dynamic Patterns (VSDP) method for the analysis of coordination in psychotherapeutic conversation. The objectives of its development are to empirically account for vocal coordination patterns in dialogs and to examine the association between interactional coordination and positive relational outcomes. The VSDP method makes it possible to demonstrate that vocal activity is a nonverbal phenomenon entwined with and which influences the linguistic code. The analyses which can be carried out through this method are illustrated with real acoustic signals taken from psychotherapy segments. The VSDP method is discussed, considering its usefulness for psychotherapeutic research as well as the study of dyadic conversation within other scenarios.

Resumen Este trabajo presenta el método de Patrones Dinámicos de Vocalización-Silencio (PDVS) para el análisis de la coordinación en la conversación psicoterapéutica. Los objetivos de su desarrollo son dar cuenta empíricamente de los patrones de coordinación vocales en diálogos y examinar la asociación entre la coordinación interaccional y los resultados relacionales positivos. El método PDVS hace posible demostrar que la actividad vocal es un fenómeno no verbal entrelazado con y que influye en el código lingüístico. Los análisis que se pueden realizar a través de este método se ilustran con señales acústicas reales tomadas de segmentos de psicoterapia. El método PDVS es discutido teniendo en cuenta su utilidad para la investigación en psicoterapia, así como para el estudio de la conversación diádica dentro de otros escenarios.

Enfermedad de Blount: osteotomía con injerto óseo de peroné / Blount´s disease: osteotomy with bony implant of fibula

Fundamento: la enfermedad de Blount afecta la metafisis interna de la tibia superior y se caracteriza por presentación clínica de tibia vara, puede ser unilateral o bilateral y estar asociada a torción tibial interna. Objetivo: presentar un caso de enfermedad de Blount la cual fue diagnosticada en consulta externa por medio del examen clínico y radiografías. Caso clínico: paciente femenina de cinco años de edad, de raza negra que presentaba un defecto en la pierna, al ser valorada por un especialista, se le indicó tratamiento con calzado ortopédico, al no mejorar es llevada a consulta externa donde a la exploración física se notó deformidad en varo bilateral de las piernas. Se indicó radiografía antero posterior y lateral de las piernas, donde se vio una imagen compatible con la enfermedad de Blount, se decide ingresar a la paciente para tratamiento quirúrgico mediante osteotomía interna valgizante de la tibia e injerto de peroné. Conclusiones: la enfermedad de Blount se considera un diagnóstico poco frecuente. El tratamiento de elección en este caso fue el quirúrgico con osteotomía abierta valgizante de tibia e injerto de peroné, al ser una técnica menos invasiva sobre partes óseas, no necesitar fijación complementaria y presentar escasas complicaciones.

Background: blount's disease affects the internal metaphysis of the upper tibia and is characterized by clinical presentation rod tibia, may be unilateral or bilateral and be associated with internal tibial torsion. Objective: to present a case of Blount’s disease which was diagnosed in external checkup by clinical examination and radiographs. Clinical case: a five-year-old black female patient of black skin color. Her mother reports that the girl was born with very twisty legs and was taken to be assessed by a doctor, who indicated treatment with orthopedic footwear. After not achieving improvement, she is brought to external chekup where physical examination deformity was noted in bilateral varus of the lower extremities. Posterior and lateral radiograph of the legs was indicated, where a compatible image was seen with Blount's disease. Hospitalizing the patient for surgical treatment by internal valgus tibial osteotomy and grafting of fibula was decided. Conclusions: blount's disease is considered a rare diagnosis. The treatment of choice was surgical with valgus osteotomy open tibia and fibula graft, since it is a less invasive technique over bony parts. It does not need supplemental fixation and presents few complications.
