RESUMO

The use of mobile phones has dramatically increased all over the world. Such revolution in the communication amongst individuals has a great impact in patient care, supporting their self-management and promoting shared responsibility with health services. Given that improved communication facilitates compliance with scheduled procedures and reduces surgical cancellations, the current work aims to develop a communication tool named Surgery Remember@ to mitigate surgical suspensions due to patient absenteeism. The present article is a study of technological production divided into four chapters: literature review; analysis of the hospital administrative profile; software development; and process mapping for software implementation. Taking into account that in the last three years the problem of absenteeism was the main cause of institutional surgical cancellations; the development of Surgery Remember@ endeavours to reduce surgery cancellations, improving efficiency and reducing costs. It is known that sending messages three days before the surgical procedure makes it possible to replace patients in the event of cancellations, optimizing the human and material resources in the operating room. The confirmation of the pre-aesthetic consultation is also positive, for it allows the verification of perioperative assistance improvement. Hence, besides being viable and easy to implement, the software developed allows the addition of other features based on user requirements, proving to be an asset to reduce surgery cancellations.

RESUMO O uso de telefones celulares aumentou dramaticamente em todo o mundo. Essa revolução na comunicação entre os indivíduos tem impacto no cuidado ao paciente, apoiando sua autogestão e promovendo a responsabilidade compartilhada com os serviços de saúde. Tendo em vista que a melhoria da comunicação facilita o cumprimento dos procedimentos programados e reduz os cancelamentos cirúrgicos, o presente trabalho tem como objetivo desenvolver uma ferramenta de comunicação denominada Surgery Remember@ para mitigar as suspensões cirúrgicas por absenteísmo do paciente. O presente artigo é um estudo da produção tecnológica dividido em quatro capítulos: revisão de literatura; análise do perfil administrativo do hospital; desenvolvimento de software; e mapeamento de processos para implementação de software. Tendo em conta que nos últimos três anos o problema do absenteísmo foi a principal causa de cancelamentos cirúrgicos institucionais o desenvolvimento do Surgery Remember@ se apresenta como esforço para reduzir os cancelamentos de cirurgias, melhorando a eficiência e reduzindo custos. Sabe-se que o envio de mensagens três dias antes do procedimento cirúrgico possibilita a reposição de pacientes em caso de cancelamentos, otimizando os recursos humanos e materiais da sala cirúrgica. A confirmação da consulta pré-anestésica também é positiva, pois permite verificar a melhora da assistência perioperatória. Assim, além de viável e de fácil implementação, o software desenvolvido permite agregar outros recursos de acordo com a necessidade do usuário, mostrando-se uma ferramenta para redução de cancelamentos cirúrgicos.

RESUMO

Abstract The growth of the urban population raises concern about municipal public managers in the sense of providing emergency medical services (EMS) that are aligned with the needs of prehospital emergency medical care demanded by the population. The literature review aims at presenting the response time of emergency medical services in several parts of the world and discussing some factors that interfere in the result of this indicator such as GDP (Gross Domestic Product) percentage spent on health and life expectancy of countries. The study will also show that in some of the consulted articles, authors suggest to EMS recommendations for decreasing the response time using simulations, heuristics and metaheuristics. Response time is a basic indicator of emergency medical services, in such a way that researchers use the descriptive statistics to evaluate this parameter. Europe and the USA outstand in the publication of studies that present this information. Some articles use stochastic and mathematical methods to suggest models that simulate scenarios of response time reduction and suggest such proposals to the local EMS. Countries in which the response time was identified have a high index of human development and life expectancy between 74.7 and 83.7 years.

RESUMO

Objective: to assess the prevalence of abnormalities found by computed tomography (CT) of the chest in patients with squamous cell carcinoma of the head and neck. Methods: we retrospectively analyzed chest CT exams of 209 patients with squamous cell carcinoma of the head and neck. The CT findings were stratified as inflammatory / infectious, parenchymal, nodular uncharacteristic and nodular metastatic / tumoral Results: alterations were diagnosed in 66.6% of patients. Of these, 25.3% represented emphysema; 18.8%, uncharacteristic micronodules; 12.9%, metastases; 11.9%, thoracic lymph node enlargements; and in 6.6% we detected active pulmonary tuberculosis or its sequelae, pneumonia or inflammatory / infectious signs and pleural thickening or effusion. Conclusion: the prevalence of exams with alterations and the considerable rate of detected metastases indicate that chest CT should be required for diagnostic and / or staging in cases of head and neck cancer.

Objetivo: avaliar a prevalência de alterações encontradas na tomografia computadorizada (TC) de tórax em pacientes com carcinoma epidermóide de cabeça e pescoço. Métodos: Foram analisadas retrospectivamente 209 TC de tórax de pacientes com carcinoma epidermoide de cabeça e pescoço. As alterações tomográficas foram estratificadas como: inflamatórias/infecciosas, parenquimatosas, nodulares incaracterísticas e nodulares metastáticas/tumorais Resultados: foram diagnosticadas alterações em 66,6 % dos exames. Destes, 25,3% representaram enfisema pulmonar; 18,8% micronódulos incaracterísticos; 12,9% metástases; 11,9% de linfonodomegalias torácicas; e, em 6,6%, foram detectadas tuberculose pulmonar ativa ou sequela, pneumonia ou sinais inflamatórios/infecciosos e espessamento ou derrame pleural. Conclusão: a prevalência de exames com alteração e o considerável índice de metástases detectadas, indicam que a TC de tórax deve ser solicitada para complementação diagnóstica e/ou estadiamento nos casos de câncer de cabeça e pescoço.

RESUMO

ABSTRACT INTRODUCTION: Peripheric nerve tumors typically derive from Schwann cells of the peripheral nerve sheet. Since these tumors are uncommon, they should be considered in preoperative differential diagnosis. OBJECTIVE: To report the experience of a tertiary care department. METHODS: Forty-two patients with head and neck peripheral neurogenic tumors were retrospectively analyzed and evaluated from 1977 to 2013. The preoperative diagnosis was confirmed by biopsy or imaging study. RESULTS: The mean age was 41.7 and 15 patients (36%) were male. The mean size was 5.5 cm and 26 (61%) were located laterally in the neck. Most tumors (39.9%) presented as an asymptomatic neck mass. Most (39.9%) were resected through a neck approach. Cranial nerves were the commonest site of origin. CONCLUSIONS: Extracranial neurogenic tumors presented with a mean size of 5.5 cm, were located laterally in the neck, normally had their origin from cranial nerves, and their resection approach is cervical.

Resumo INTRODUÇÃO: Tumores dos nervos periféricos tipicamente derivam das células de Schwann da bainha dos nervos periféricos. Por serem incomuns, devem ser lembrados no diagnóstico diferencial pré-operatório. OBJETIVO: Relatar a experiência de serviço de referencia terciária. MÉTODO: De 1977 a 2013, 42 pacientes com tumores neurogênicos periféricos da cabeça e pescoço foram operados e analisados retrospectivamente. A confirmação diagnóstica pré-operatória deu-se por biópsia ou método de imagem. RESULTADOS: A média da idade foi de 41,7 anos, sendo 15 indivíduos (36%) do gênero masculino. O tamanho médio foi de 5,5 cm e 26 (61%) localizavam-se na face lateral do pescoço. A maior parte (39,9%) apresentou-se como tumor palpável assintomático. A maioria (39,9%) foi ressecadapor acesso cervical. A maioria originou-se de nervos cranianos. CONCLUSÕES: Tumores neurogênicos extracranianos apresentam-se com tamanho médio de 5,5 cm, na face lateral do pescoço, costumam originar-se de nervos cranianos e ser ressecados por via cervical.
