Objetivo: Analisar a influência da microbiota cutânea na dermatite atópica infantil. Revisão bibliográfica: Dermatite atópica (DA) é uma inflamação cutânea que resulta no aparecimento de lesões e coceira na pele, podendo afetar indivíduos de diferentes faixas etárias, em especial crianças. Em função da constante exposição ao meio externo, a epiderme possui alguns mecanismos que atuam como uma barreira natural de proteção, a exemplo da microbiota cutânea. Constituído por microrganismos comensais, este microbioma sofre a influência de diversos fatores que, uma vez em desequilíbrio, transformam a região suscetível ao surgimento de dermatite atópica. Dessa forma, estudos comprovam que pacientes com DA apresentam certo domínio na colonização cutânea por Staphylococcus aureus, atestando que existe uma correspondência entre o grau de intensidade da inflamação com a quantidade de bactérias nas lesões. Considerações finais: A falta de exposição da microbiota cutânea a uma diversidade microbiana na infância gera uma baixa tolerância imunológica que pode influenciar no desenvolvimento da dermatite atópica em pacientes pediátricos.

Authors: Dhanasekar Elanchezhian , Saranya R. , Konduru Rajesh Kumar , Kumar Pradeep
Published: October 2024

The Intensified Mission Indradhanush 5.0 (IMI 5.0) aimed to extend routine immunization services across India, with a focus on children up to 5 years old. Key objectives included boosting measles and rubella vaccination coverage. By September 30, 2023, over 34.6 million children and 6.5 million pregnant women had received vaccine doses nationally. The Surveillance Medical Officer (SMO) from WHO designated external monitors to oversee session sites and perform house-to-house monitoring. Monitoring took place from October 12-14, 2023, in three health blocks of Cuddalore District. Activities included observing two session sites per day (six total) and surveying 40 households per day (120 total). Separate checklists were provided for session site monitoring and house-to-house monitoring, as per WHO guidelines. All session sites adhered to the scheduled times and locations, with proper logistics. However, some lacked IEC materials for public awareness. House-to-house monitoring confirmed full vaccination coverage for under-five children, with no missed vaccinations identified. Recommendations were made to ANMs to have IEC material to enhance community participation. Monitoring of IMI 5.0 in Cuddalore District demonstrated strong adherence to guidelines and effective vaccination session implementation. House-to-house monitoring confirmed appropriate vaccination of under-five children, indicating successful outreach. Overall, this experience provided valuable insights into operational challenges and opportunities for improvement in future immunization campaigns.
Longitudinal tooth fracture indicating a questionable prognosis for an endodontist
Authors: Gupta Sonu , Garg Ruchika , Bansal Ravinder Nath
Published: October 2024

Introduction and Objectives:

Longitudinal fracture or vertical fracture of a tooth occurs at any level in the root and extends vertically. It has a high incidence of occurrence in the first molars. The most frequent sites to occur are the buccolingual surface and proximal surfaces of teeth. The etiology of fracture involves different factors in endodontically treated and non-endodontically treated teeth. Longitudinal fractures become the most challenging to diagnose and treat. This paper reviews these aspects of challenges and discusses the advantages and limitations of dental materials used for the treatment.

Review Methods:

PubMed and Google Scholar databases were searched for articles on longitudinal tooth fractures between 2007 and 2022. The 16 current articles were selected.

Brief Description of the State of Knowledge:

As per the review of the literature, longitudinal fracture of the tooth is the most common fracture to occur due to excessive forces on the root canal-treated tooth. This occurs in endodontically treated teeth due to long-term application of calcium hydroxide, cracks caused during root canal preparation extended by the pressure of root canal obturation, and in non-endodontically treated teeth due to cyclic and heavy masticatory stress, and habitual chewing of hard food especially in males.

Functional and esthetic outcomes following longitudinal fracture treatment are important considerations in the case of anterior teeth. Longitudinal fracture or vertical fracture of a tooth occurs mostly in the first molars. It is crucial to identify and manage actors for good prognosis, as restoration at a time can reduce fracture extension prevent microleakage.
Mimickers of erysipelas and cellulitis: A narrative review
Authors: Gowda Shreya K , Garg Sonika , Behera Biswanath , Thakur Vishal , Sahu Deepak Kumar
Published: October 2024

A diffuse erythematous, edematous tender swelling with a distinct border and local rise in temperature suggest a morphological diagnosis of erysipelas-like eruption. While cellulitis and pseudocellulitis have an ill defined tender erythematous plaque. Erysipelas, and cellulitis are not a straightforward diagnosis as multiple cutaneous eruptions mimic erysipelas. It is important to have comprehensive knowledge about the different causes of erysipelas-like eruptions and pseudocellulitis to reach a diagnosis and treat appropriately. Many infectious diseases such as histoplasmosis, leishmaniasis, dermatophytosis, and infusion of chemotherapeutic agents result in erysipelas-like eruptions and pseudocellulitis. Malignancy-related dermatoses such as carcinoma erysipeloides, erysipeloides melanomatosum, and inflammatory dermatoses such as sweet syndrome, well syndrome, and Crohn’s disease present as erysipelas-like eruption.

Published: October 2024

Nocardiosis is an opportunistic infectious disease in immunocompromised individuals, which may be fatal and in people with healthy immune systems, which is reported as a case. Mixed infections with Nocardia and Mycobacterium tuberculosis complex (MTBC) are rare. We are reporting a case of co-infection with Nocardia spp. and MTBC in an immunocompetent patient presenting with neck swelling. Interestingly, in this case, the primary identification of Nocardia was done using 20% H2SO4 as decolorizer for Ziehl–Neelsen staining. The patient was given first-line anti-tubercular treatment for the first 2 months as an intensive phase, followed by isoniazid and rifampicin for an additional 4 months, with a total of 6 months treatment, along with linezolid (600 mg twice daily for 15 days). The patient subsequently improved.
Papillary carcinoma arising from de novo ectopic thyroid tissue within thyroglossal duct cyst: A rare case report
Authors: Pradhan Rajashree , Dutta Abhishek , Mondal Sajeeb , Mukherjee Upasana
Published: October 2024

The most common congenital anomaly of thyroglossal duct is a thyroglossal duct cyst, but carcinoma arising from a thyroglossal duct cyst is a rare phenomenon. Carcinomas involving thyroglossal duct cysts are mostly papillary carcinomas. Definitive diagnosis of carcinomas involving thyroglossal duct cysts is done through surgical excision and subsequent histopathological examination. Most carcinomas arise de novo from ectopic thyroid tissue within thyroglossal duct cysts, but the direct spread of papillary carcinomas arising from the thyroid gland can also present themselves as carcinomas involving thyroglossal duct cysts in a minority of patients. Clinical presentation in most of the patients with carcinoma of thyroglossal duct cyst is quite similar to that of the patients with histopathologically diagnosed thyroglossal duct cyst, i.e., a painless anterior midline neck swelling with cosmetic concern and no other significant symptom(s). Careful clinical examination, imaging techniques, fine needle aspiration cytology, etc., can be helpful in indicating the presence of carcinoma preoperatively. Management of patients with thyroglossal duct cyst carcinoma involves only the Sistrunk procedure in the majority of cases. However, in a minority of patients, management by Sis trunk procedure with additional total thyroidectomy (with or without dissection of lymph nodes of the neck) and adjuvant chemo and radio-ablation therapies are needed. Here, we report a case of a 17-year-old female with papillary carcinoma involving thyroglossal duct cyst who presented with a submental swelling and was eventually managed by Sis trunk procedure, total thyroidectomy, and adjuvant therapies for optical cure. Decisions for the management of her cancer were taken through multidisciplinary interactions at tumor board meetings and by judging her surgical and therapeutic needs based on her clinical, radiological, and pathological findings.
A theoretical approach to design communication in mixed traffic
Authors:   Universität Stuttgart, Gadermann Lars , Holder Daniel ,   Universität Stuttgart, Maier Thomas ,   Universität Stuttgart
Published: October 2024

Effective communication between automated vehicles (AVs) and human road users (HRU) in mixed traffic is essential for ensuring safety, trust and acceptance. However, existing research on external Human-Machine Interfaces (eHMI) for AVs often overlooks design factors and their interconnections, leading to suboptimal designs. This article presents a comprehensive framework of Human-Machine Interaction in mixed traffic, integrating different relevant stakeholders, influencing factors, and relationships. By visualizing the interactions during communication and with the surrounding environment, the framework serves as a valuable tool for research and development of eHMI, maintaining a comprehensive perspective. Key challenges include determining optimal design features, such as message transmission methods and integration into the vehicle exterior design, and considering diverse human factors, such as age, culture, and cognitive abilities. By addressing these challenges, future eHMI designs can enhance user acceptance and trust in AVs, contributing to safer and more efficient mixed traffic environments. Further research will delve into the detailed examination of design factors and the interaction between interior and exterior vehicle interfaces.

As we move towards a sustainable future, designing technology plays a key role. Over the last few decades, the role of design has been steadily expanding from a purely economic benefit for products to a discipline that contributes to positive change for humanity. While the recognition of this responsibility is growing, there is a knowledge gap for design practice. What is a contemporary design approach and how does it translate into practice? We briefly review three major design movements (human-centred design, participatory design, design for sustainability) and introduce the human-driven design approach, which integrates all three perspectives into the design of technology. To explore the gap between human-centred design theory and design practice, we reflect on three use cases. Finally, this paper provides insights into how human-driven design can be implemented in practice and presents four key issues that require action: Stakeholder management, faster horses, prototyping for disruptive scenarios and methods for sustainability.

В условиях волатильности мирового энергетического рынка и топливно-энергетического баланса роль угля как одного из ведущих энергоносителей будет постоянно укрепляться, что определит тенденцию к повышению добычи для угледобывающих компаний. Это невозможно без решения ряда проблем, связанных с изменениями существующих технологий по подземной добыче угля, которые требуют тесной связи науки и производства для организации и проведения междисциплинарных исследований. Наиболее эффективными с экономической точки зрения организационно-техническими мероприятиями для этого являются: увеличение длины очистного забоя и сокращение времени, затрачиваемого на концевые операции. При этом необходимо учитывать соответствие принимаемых технических решений конкретным горно-геологическим и горнотехническим условиям. В статье выполнен краткий анализ ряда технико-экономических показателей, достигнутых при работе очистных забоев в России и за рубежом. Результаты анализа подтверждают правильность предлагаемых решений.

With the volatility of the global energy market and the fuel and energy balance, the role of coal as one of the leading energy carriers will be constantly strengthened, which will determine the trend towards higher production for coal mining companies. This is not possible without solving a number of problems associated with changes in existing underground coal mining technologies that require a close science- production link to organize and conduct interdisciplinary research.The most cost-effective organizational and technical measures for this are to increase the length of the productive workings and reduce the time spent on end operations. At the same time, it is necessary to take into account the compliance of the technical decisions taken with specific mining-geological and mining technical conditions.In the article, a brief analysis of a number of technical and economic indicators achieved during the work of productive workings in Russia and abroad was carried out. The results of the analysis confirm the correctness of the proposed solutions.

В статье представлена методика определения потенциально выбросоопасных зон угольного пласта с учетом механодеструкции угля. Существующие способы прогноза выбросоопасности угольных пластов не учитывают газ, выделяющийся при разрушении угля. С помощью разработанной методики можно делать заключение о потенциальной выбросоопасности участка угольного пласта по величине интенсивности газовыделения из разрушенного угля. Методика предполагает определение удельной интенсивности газовыделения и объёма разрушенного угля. Если экспериментально установленная интенсивность газовыделения Qэкс > Qкрит, то данный участок пласта считается выбросоопасным. Критическую интенсивность газовыделения рассчитывают с учётом параметров данного шахтопласта.

The article presents the procedure for determining potentially emission-hazardous zones of the coal bed taking into account the mechanical degradation of coal. Existing methods of predicting the emission hazard of coalseam do not take into account the gas released by the destruction of coal. With the help of the developed method it is possible to make a conclusion on potential emission hazard of the coal bed section by the value of gas release intensity from the broken coal. The technique involves determination of specific intensity of gas release and volume of broken coal. If experimentally determined intensity of gasrelease Qex > Qcrite, this section of formation is considered to be hazardous. Critical intensity of gas release is calculated taking into account parameters of this mine mill.

Besides, it is established, that the workplace of most mining workers do not meet safety and hygiene requirements, which leads to injuries of varying severity, the development of diseases caused by harmful production factors, increasing the risk of occupational diseases.
РЕЗУЛЬТАТЫ МОДЕЛИРОВАНИЯ ТРАЕКТОРИИ ДИСКОВОЙ ТРЕЩИНЫ ГИДРОРАЗРЫВА В ОКРЕСТНОСТИ ШТРЕКОВОЙ ВЫРАБОТКИ
Authors: Черданцев Н.В.
Published: October 2024

Модель геомеханического состояния дисковой трещины гидроразрыва, распространяющейся в прочных горных породах в окрестности пластовой выработки построена на основных положениях механики хрупкого разрушения Гриффитса-Ирвина и механики деформируемого твёрдого тела.Поле напряжений в углепородном массиве, вмещающем пластовую выработку и растущую трещину гидроразрыва, построено путём решения упругопластической задачи, в которой областью пластичности являются предельно напряжённые краевые зоны пласта. Критериями наступления предельного состояния являются общий критерий Кулона-Мора по пласту и специальный критерий по его контакту с массивом. На основе анализа полученных результатов выявлены следующие особенности в распространении трещины. При относительно небольших рабочих давлениях жидкости в насосной установке траектория трещины гидроразрыва представляет собой плавную кривую линию небольшого размера и значительным отклонением её концов от направления зародышевой трещины. С увеличением рабочего давления жидкости длина трещины гидроразрыва увеличивается, а её отклонение от направления зародышевой трещины уменьшается. При некотором значении давления жидкости и ориентации зародышевой трещины относительно выработки она распространяется прямолинейно и практически не меняет направления.

The model of the geomechanical state of the hydraulic fracturing disk crack propagating in strong rocks in the vicinity of the formation mine is based on the main positions of the Griffiths-Irwin brittle fracture mechanics and the mechanics of the deformable solid. The stress field in the carbon mass containing the formation and the growing fracture of hydraulic fracturing is built by solving the elastoplastic problem in which the area of plasticity is the extremely stressed edge zones of the formation. The criteria for the onset of the limit state are the general Coulomb- Mor criterion for the formation and a special criterion for its contact with the array. Based on the analysis of the obtained results, the following features in crack propagation were identified. With relatively small operating fluid pressures in the pump unit, the fracturing crack trajectory is a smooth curve line of small size and a significant deviation of its ends from the direction of the germ crack. With an increase in the working pressure of the liquid, the length of the fracturing crack increases, and its deviation from the direction of the germ crack decreases. With a certain value of the fluid pressure and the orientation of the germ crack relative to the production, it propagates rectilinear and practically does not change direction.
