Finite element method in equine orthopedics

Published on: 31st May, 2021

OCLC Number/Unique Identifier: 9124797192

The finite element method (FEM) is an engineering resource used to predict the stresses in structures that have complex geometries, specific material properties and are subject to complex loading patterns, being widely used in medical and biological research. It has the advantage of being a noninvasive and accurate method, which provides quantitative and detailed data about the physiological reactions that can occur in the tissues [1-5].

Rare Presentation of Chromoblastomycosis Due to Multiple Simultaneous Inoculations: A Case Report

Published on: 7th August, 2023

Chronic infectious, granulomatous and suppurative dermatosis, classified among the subcutaneous mycoses, prevalent in tropical and subtropical regions and caused by the traumatic implantation of dematiaceous fungal species, where the presence of muriform bodies is an expression of the causal agent in the grafted tissue, are characteristic of chromoblastomycosis. Considered the second implantation mycosis in the world, it manifests itself with slow and progressive growth lesions of exophytic and verrucous plaques and black dots on the surface.The disease is considered a neglected and occupational disease, which occurs mainly among agricultural workers, coconut and babassu harvesters, lumberjacks, and traders of agricultural products. It is important to highlight that people at risk of contracting chromoblastomycosis work in tropical countries, where the temperature can be above 40 °C in summer, and generally refuse to wear protective equipment during the day (shoes, gloves, clothes, etc.), although they know that this type of prophylactic measure can prevent different types of diseases. These vulnerable people often live in low-income countries and sometimes live far from medical services and, once infected, do not seek medical attention. We report below an exuberant and unusual case due to multiple simultaneous inoculations on the back after the patient suffered an accidental fall while working on his farm. The diagnosis was established by direct mycological examination, histopathological examination, culture, microculture, and MALDI-TOF MS analysis that identified the agent of the Fonsecaea pedrosoi.

Orthodontic Patients’ Perception of Orthodontic Office Changes during COVID-19 Pandemic in Brazil: A National Cross-Sectional Survey

Published on: 7th September, 2023

There is still limited information regarding patients’ perception of the dental approach changes in the pandemic circumstance. Therefore, the aims of this study were, firstly, to evaluate patient perception regarding the COVID-19 infection risk in the orthodontic office in Brazil, and to assess the influence of age in infection risk perception. Orthodontic patients from five states answered an online questionnaire, anonymously, about quarantine behavior, perception of the infection risk in the orthodontic office, as well as the apparent need for the new biosafety approach. Descriptive analyses were performed for each question. Correlations between age and concern of getting infected were calculated with Spearman correlation tests. There were 406 responses. Most patients respected the quarantine, and 93.10% of those who were scheduled for appointments realized that their appointment would be safe enough. From the total, 83.99%, 84.98%, 89.90%, and 95.81% of patients judged, respectively, health status checks by phone, temperature checking, disposable coat, and face shield, as necessary. Only 6.40% reported an increase in the concern of returning to appointments. The younger the patient, the greater the concern of getting infected in future appointments (p = 0.042). Most patients were confident in the professional care before the appointment. The new biosafety approach was well accepted by the majority, with less agreement with temperature checking and the use of disposable coats. The younger the patient, the greater the concern of getting infected in future appointments. The rate of patients with risk factors for COVID-19 was 14.77%.
