A utilização de aparelhos eletrocirúrgicos em cirurgias periodontais: uma revisão de literatura, 2015-2020: The use of electrosurgical devices in periodontal surgery: a literature review, 2015-2020

Os dispositivos eletrocirúrgicos promovem hemostasia e possuem funções de corte, coagulação e dissecação dos tecidos. No entanto, estudos que avaliem o uso da eletrocirurgia em periodontia apresentam contradições. O presente estudo tem por objetivo revisar a literatura quanto a utilização de aparelhos eletrocirúrgicos em cirurgias periodontais. Realizou-se uma busca por artigos nas bases de dados PubMed e Portal Regional da BVS, utilizando os descritores: “periodontics” OR “gingiva” AND “electrosurgery”. A busca resultou em 33 artigos, dos quais, após aplicação dos critérios de inclusão e exclusão, procederam-se à seleção de 07 artigos. Os artigos demonstraram que a hemostasia proporcionada pelos dispositivos eletrocirúrgicos permite uma melhor visualização do campo cirúrgico, além de apresentarem um baixo custo em relação aos dispositivos de laser. Considera-se que os aparelhos de bisturis elétricos são dispositivos de fácil utilização, capazes de otimizar a execução de técnicas cirúrgicas periodontais, no entanto requerem preparo prévio dos profissionais para seu uso adequado

Peripheral ossifying fibroma:a 20-year retrospective study with focus on clinical and morphological features

Peripheral Ossifying Fibroma (POF) is a reactive hyperplastic lesion that exclusively occurs in the gingiva and is characterized by the deposition of dystrophic calcification, cementum-like tissue, and immature and mature bone within the connective tissue. The objective of the present study was to perform a retrospective analysis of clinicopathologic features of POF. Clinical and histopathological data were obtained from biopsy records and histopathological reports from a Brazilian reference service in Oral Pathology (1999 - 2020). Morphological analysis was performed to evaluate features related to the mesenchymal component, inflammatory infiltrate, ulceration, and mineralized tissue. A total of 270 POFs were diagnosed during the study period. A higher frequency was observed in females (71.9%) between the third (22.9%) and fourth (23.3%) decades of life. The anterior upper gingiva (29.1%) was the most affected region. Mature (86.7%) and immature (52.6%) bone tissue were the most frequent. There was a significant association between immature bone deposition and lesions with size ? 1.7 cm (p = 0.041); immature bone and cement-like tissue deposition with an evolution time ? 16 months (p < 0.001); deposition of immature bone and mesenchymal hypercellularization (p < 0.001); deposition of dystrophic calcification and the presence of ulceration (p < 0.001). The clinical characteristics corroborate the findings in the literature. The heterogeneous distribution and quantity of mineralized tissues found in the analyzed cases support the theory that the different mineralized tissues constitute a spectrum of clinical maturation of POF

Previous exposure to musical auditory stimulation immediately influences the cardiac autonomic responses to the postural change maneuver in women

Background\ud Chronic exposure to musical auditory stimulation has been reported to improve cardiac autonomic regulation. However, it is not clear if music acutely influences it in response to autonomic tests. We evaluated the acute effects of music on heart rate variability (HRV) responses to the postural change maneuver (PCM) in women.\ud \ud Method\ud We evaluated 12 healthy women between 18 and 28 years old and HRV was analyzed in the time (SDNN, RMSSD, NN50 and pNN50) and frequency (LF, HF and LF/HF ratio) domains. In the control protocol, the women remained at seated rest for 10 minutes and quickly stood up within three seconds and remained standing still for 15 minutes. In the music protocol, the women remained at seated rest for 10 minutes, were exposed to music for 10 minutes and quickly stood up within three seconds and remained standing still for 15 minutes. HRV was recorded at the following time: rest, music (music protocol) 0–5, 5–10 and 10–15 min during standing.\ud \ud Results\ud In the control protocol the SDNN, RMSSD and pNN50 indexes were reduced at 10–15 minutes after the volunteers stood up, while the LF (nu) index was increased at the same moment compared to seated rest. In the protocol with music, the indexes were not different from control but the RMSSD, pNN50 and LF (nu) were different from the music period.\ud \ud Conclusion\ud Musical auditory stimulation attenuates the cardiac autonomic responses to the PCM.This study received financial support from Fundação para o Desenvolvimento da UNESP (FUNDUNESP – Process number 9139213)

PREVALÊNCIA DE COMPLICAÇÕES RESPIRATÓRIAS NA UNIDADE DE TERAPIA INTENSIVA ADULTO

Introduction: Patients admitted to the Intensive Care Unit (ICU) are subject to a high demand for invasive mechanisms that increase the chances of developing complications. Objectives: to identify the main respiratory complications in the adult ICU. Materials and Methods: 104 medical records of patients admitted to the ICU were analyzed. The following programs were used for data accounting: Statistical Package for Social Science (SPSS) software, version 25®, Shapiro-Wilk test, Mann-Whitney test. Results: There was an average predominance of 51.9% women and 48.1% men, with a mean age of 65.22 ± 20.83 years. The average length of stay in the ICU is 14.23±12.89. The total length of stay 21.45±18.05. The duration of use of mechanical ventilation was 40% for a period of 1 to 7 days, 21.7% for more than 20 days, 16.7% for a period of 10 to 15 days, 15% for a period of 7 to 10 days, 6.7% from 15 to 20 days. Where 49.5% had respiratory complications (n ​​= 50), among the most prevalent complications in the analyzed sample are pneumonia in 18.8%, sepsis or septic shock in 16.7%. Conclusion: It was found that the most prevalent respiratory complication was pneumonia, which may be related to the use of mechanical ventilation, a fact that demonstrates the need for increased care to prevent this complication. Based on the results, prospective studies with more robust samples are needed to confirm such trends.Introdução: Os pacientes internados na Unidade de Terapia Intensiva (UTI) estão sujeitos à alta demanda de mecanismos invasivos que aumentam as chances de desenvolverem complicações.

Economic Losses and Cross Border Effects Caused by Pantanal Catastrophic Wildfires

The Pantanal, the Earth's largest continuous wetland, experienced severe impacts from wildfires in 2019 and, particularly, in 2020. The surge in wildfires can be attributed to several factors, including climate extremes, inadequate fire management, ineffective policymaking, as well as commercial and demographic dynamics. Understanding the economic effects of wildfires is crucial for guiding resource allocation toward prevention and firefighting efforts. This study aims to examine the economic losses resulting from the catastrophic wildfires in the Brazilian Pantanal region during 2019 and 2020. By utilizing publicly available datasets and data obtained from representatives of public and private institutions, we constructed scenarios to simulate the fire's impacts on economic input-output matrices. Through the application of structural impact analysis, we can simulate variations in output, value-added, and income by considering demand variation scenarios resulting from external shocks. Our findings reveal that the economic impact of the wildfires extends beyond the burned areas, affecting other regions of Brazil, such as São Paulo and Paraná. The lack of a comprehensive public database encompassing different scales (municipal, state, and national), along with a clear methodology for calculating and reporting firefighting expenses, hinders accurate prediction of economic losses and impedes proactive investments in wildfire prevention

O PACIENTE COM TRANSTORNO MENTAL: A PERCEPÇÃO DE FAMILIARES CUIDADORES ACERCA DESSA CONDIÇÃO

This is a qualitative and descriptive study, whose objective was to verify the perception of caregivers about patients with mental disorders treated in the public health network in the city of Montes Claros-MG. The work was developed at the Psychosocial Care Center (CAPS). The data were obtained through a focal group and analyzed through the discourse analysis technique. After data collection, categories related to the difficulties and challenges encountered by caregivers, patient behavior and caregiver overload emerged. It was concluded that the family caregiver of the mentally ill person presents suffering and lack of information. This demonstrates the need to bring the health team closer to the caregiver, since this interaction may contribute to the process of mitigating the responsibility of caring.Trata-se de um estudo qualitativo e descritivo, cujo o objetivo foi verificar a percepção de cuidadores acerca de pacientes com transtornos mentais atendidos na rede pública de saúde na cidade de Montes Claros-MG. O trabalho foi desenvolvido no centro de atenção psicossocial (CAPS). Os dados foram obtidos através da realização de um grupo focal e analisados através da técnica de análise do discurso. Após a coleta de dados surgiram categorias relacionadas as dificuldades e desafios encontrados pelos cuidadores, comportamento do paciente e sobrecarga dos cuidadores. Concluiu-se que o familiar cuidador do portador de transtorno mental apresenta sofrimento e carência de informação. Isso demonstra a necessidade da aproximar a equipe de saúde ao cuidador, pois essa interação poderá contribuir no processo de amenização da responsabilidade do ato de cuida

Repercussões Respiratórias no Pós – Operatório de Câncer de Mama

Introduction: Cancer is defined as a disorderly proliferation of cells that can spread and invade tissues and/or organs throughout the body, when a genetic mutation occurs, the deoxyribonucleic acid (DNA) undergoes an erroneous change of orders on how to multiply, classified as cancer cells, named according to their multiplication speed and ability to spread to other tissues. Objective: Check the respiratory repercussions in the postoperative period of breast câncer. Method: This is a descriptive, cross-sectional study with quantitative analysis, carried out with 20 female individuals in the postoperative period of breast cancer who were undergoing treatment at a Specialty Outpatient Clinic in Montes Claros - Minas Gerais. The instruments used were the MRC scale, which assesses the level of dyspnea during physical activity, cirtometry, which assesses chest expansion, and a manovacuometer, which measures respiratory muscle strength. Results: The average age of the participants was 50.40 ± 5.50, it was observed that 90.0% of the participants feel short of breath only during intense exercises, according to the MRC scale, in the cirtometry all the subjects showed a reduction in expandability thoracic. A significant decrease in respiratory muscle strength was observed, the average percentage achieved in forced inspiration was 86.77% and in forced expiration its average percentage was 71.75%. Conclusion: It is concluded that patients with breast cancer who underwent a surgical procedure may have respiratory changes, that is, the population studied showed changes in muscle strength and changes in expansion, but there was no association between the level of chest expansion and type of surgery.Introdução: O câncer é definido como uma proliferação de células desordenadas que pode se espalhar e invadir tecidos e/ou órgãos por todo o corpo, quando ocorre uma mutação genética. Objetivo: Verificar as repercussões respiratórias no pós-operatório do câncer de mama. Método: Trata-se de um estudo de caráter descritivo, corte transversal e análise quantitativa, realizado com 20 indivíduos do sexo feminino no pós-operatório do câncer de mama que estavam em tratamento em um Ambulatório de Especialidade em Montes Claros - Minas Gerais. Os instrumentos utilizados foram a escala de MRC que avalia o nível de dispneia durante atividade física, cirtometria que avalia a expansibilidade torácica e manovacuômetro que mensura a força muscular respiratória. Resultados: A idade média das participantes foi de 50,40 ± 5,50, observou-se que 90,0% das participantes sente falta de ar só durante exercícios intensos, segundo a escala de MRC, na cirtometria todos os sujeitos apresentaram redução da expansibilidade torácica. Foi observado uma diminuição significativa na força muscular respiratória, a média percentual alcançada na inspiração forçada foi de 86,77% e na expiração forçada sua média percentual foi de 71,75%. Conclusão: Conclui-se que pacientes portadoras de CA de mama que foram submetidas a um procedimento cirúrgico podem apresentar alterações respiratórias, ou seja, a população estudada apresentou alteração de força muscular e alteração da expansibilidade, porém não houve associação entre nível de expansibilidade torácica e tipo de cirurgia. &nbsp

O câncer e a criança: um impacto familiar

The aim of this work is a bibliographic review concerning the children living with cancer and their family, in order to identify the themes that have been already studied and to understand the impact on the family during the phases of childhood cancer. The information acquisition was based on documents from the Ministry of Health and on scientific studies available on the following databases: the Google Scholar, the Health virtual Library, the Scielo, the CAPES Journals, the MEDLINE, the LILACS and the Cochrane. The choice of the documents and journals was mainly justified by its link with the childhood health theme. The systematic of the studies research covered the period from 1999 to 2015. The keywords used for the research’s strategy were: childhood health, childhood cancer, family caregivers and grief. The results were presented in three themes: childhood cancer impact on the family, adaptation process of the family facing the sickness and the mourning regarding the death of the sick child. The review enabled to identify the need for special follow-up of the person, which is in direct contact with the child, usually the mother, since the moment of the diagnostic, until after the death.O objetivo desse estudo é revisar a literatura relativa à criança com câncer e sua família, a fim de identificar temas que têm sido pesquisados, e compreender o impacto causado na família durante as fases do câncer infantil.
