Estrangulamento acidental em crianças por fechamento automático de vidro de carro / Accidental strangulation in children by the automatic closing of a car window

RESUMO Entre as principais causas de morte em nosso meio, situam-se acidentes automobilísticos, afogamento e queimaduras acidentais. O estrangulamento é uma injúria potencialmente fatal, além de importante causa de homicídio e suicídio em adultos e adolescentes. Em crianças, sua ocorrência é usualmente acidental. No entanto, nos últimos anos, vários casos de estrangulamento acidental em crianças ao redor do mundo têm sido reportados. Paciente masculino de 2 anos de idade foi vítima de estrangulamento em vidro do carro. Admitido na unidade de terapia intensiva pediátrica com Escala de Coma de Glasgow de 8, piora progressiva da disfunção respiratória e torpor. Paciente apresentou quadro de Síndrome da Angústia Respiratória Aguda, edema agudo de pulmão e choque. Foi manejado com ventilação mecânica protetora, drogas vosoativas e antibioticoterapia. Recebeu alta da unidade de terapia intensiva sem sequelas neurológicas ou pulmonares. Após 12 dias de internação, teve hospitalar alta para casa em ótimo estado. A incidência de estrangulamento por vidro de automóvel é rara, mas de alta morbimortalidade, devido ao mecanismo de asfixia ocasionado. Felizmente, os automóveis mais modernos dispõem de dispositivos que interrompem o fechamento automático dos vidros se for encontrada alguma resistência. No entanto, visto a gravidade das complicações de pacientes vítimas de estrangulamento, é significativamente relevante o manejo intensivo neuroventilatório e hemodinâmico das patologias envolvidas, para redução da morbimortalidade, assim como é necessário implementar novas campanhas para educação dos pais e cuidadores das crianças, visando evitar acidentes facilmente preveníveis e otimizar os mecanismos de segurança nos automóveis com vidros elétricos.

ABSTRACT Among the main causes of death in our country are car accidents, drowning and accidental burns. Strangulation is a potentially fatal injury and an important cause of homicide and suicide among adults and adolescents. In children, its occurrence is usually accidental. However, in recent years, several cases of accidental strangulation in children around the world have been reported. A 2-year-old male patient was strangled in a car window. The patient was admitted to the pediatric intensive care unit with a Glasgow Coma Scale score of 8 and presented with progressive worsening of respiratory dysfunction and torpor. The patient also presented acute respiratory distress syndrome, acute pulmonary edema and shock. He was managed with protective mechanical ventilation, vasoactive drugs and antibiotic therapy. He was discharged from the intensive care unit without neurological or pulmonary sequelae. After 12 days of hospitalization, he was discharged from the hospital, and his state was very good. The incidence of automobile window strangulation is rare but of high morbidity and mortality due to the resulting choking mechanism. Fortunately, newer cars have devices that stop the automatic closing of the windows if resistance is encountered. However, considering the severity of complications strangulated patients experience, the intensive neuro-ventilatory and hemodynamic management of the pathologies involved is important to reduce morbidity and mortality, as is the need to implement new campaigns for the education of parents and caregivers of children, aiming to avoid easily preventable accidents and to optimize safety mechanisms in cars with electric windows.

Oxigenação por membrana extracorpórea na síndrome do desconforto respiratório agudo devido à pneumonia por influenza A (H1N1) pdm09. Experiência em um único centro durante a temporada de 2013-2014 / Extracorporeal membrane oxygenation in acute respiratory distress syndrome due to influenza A (H1N1)pdm09 pneumonia. A single-center experience during the 2013-2014 season

RESUMO Objetivo: Descrever os desfechos de pacientes com síndrome do desconforto respiratório agudo associada à influenza subtipo H1N1 grave tratados com oxigenação por membrana extracorpórea. Métodos: Trata-se de revisão retrospectiva de uma coorte de pacientes oriunda de um único centro, constituída por adultos com síndrome do desconforto respiratório agudo relacionada com influenza subtipo H1N1 e tratados com oxigenação venovenosa por membrana extracorpórea durante a temporada de inverno no hemisfério norte de 2013/2014. Resultados: Dez pacientes receberam oxigenação venovenosa por membrana extracorpórea para tratamento de influenza subtipo H1N1 entre janeiro de 2013 e março de 2014. Sete deles foram transferidos para nosso centro visando à utilização de oxigenação por membrana extracorpórea dentro de um período de 72 horas após o início da ventilação mecânica. A idade mediana foi de 40 anos, sendo 30% dos pacientes do sexo feminino. O valor mediano da proporção entre pressão parcial de oxigênio e fração inspirada de oxigênio foi de 62,5, sendo o escore RESP mediano de 6. Três pacientes receberam inalação de óxido nítrico e quatro utilizaram posição prona como tratamento de resgate antes de ser iniciada a oxigenação por membrana extracorpórea. A duração mediana da ventilação mecânica foi de 22 dias (variação de 14 - 32). O tempo mediano de permanência na unidade de terapia intensiva foi de 27 dias (variação de 14 - 39). O tempo mediano de permanência no hospital foi de 29,1 dias (variação de 16,0 - 46,9). Ocorreram complicações não importantes de sangramento em seis dos dez pacientes. Oito dos dez pacientes sobreviveram até a alta hospitalar. Conclusão: Os sobreviventes eram relativamente jovens e tiveram alta com boas condições funcionais, o que salienta os anos de vida ajustados pela qualidade que foram salvos. Nossa experiência demonstra que mesmo um programa ainda relativamente novo de oxigenação por membrana extracorpórea pode desempenhar um papel importante, e proporcionar resultados excelentes para os pacientes mais graves.

ABSTRACT Objective: This report aimed to describe the outcomes of the patients with severe H1N1 associated acute respiratory distress syndrome who were treated with extracorporeal membrane oxygenation therapy. Methods: This retrospective review analyzed a single-center cohort of adult patients with H1N1-related acute respiratory distress syndrome who were managed with veno-venous extracorporeal membrane oxygenation during the winter of 2013/2014. Results: A total of 10 patients received veno-venous extracorporeal membrane oxygenation for H1N1 influenza between January 2013 and March 2014. Seven patients were transferred to our center for extracorporeal membrane oxygenation consideration (all within 72 hours of initiating mechanical ventilation). The median patient age was forty years, and 30% were female. The median arterial oxygen partial pressure to fraction of inspired oxygen ratio was 62.5, and the median RESP score was 6. Three patients received inhaled nitric oxide, and four patients were proned as rescue therapy before extracorporeal membrane oxygenation was initiated. The median duration of mechanical ventilation was twenty-two days (range, 14 - 32). The median length of stay in the intensive care unit was twenty-seven days (range, 14 - 39). The median hospital length of stay was 29.1 days (range, 16.0 - 46.9). Minor bleeding complications occurred in 6 of 10 patients. Eight of the ten patients survived to hospital discharge. Conclusion: The survivors were relatively young and discharged with good functional status (i.e., enhancing quality-adjusted life-years-saved). Our experience shows that even a relatively new extracorporeal membrane oxygenation program can play an important role in that capacity and provide excellent outcomes for the sickest patients.

Síndrome do desconforto respiratório agudo relacionada à sepse em crianças com câncer: dinâmica respiratória de uma condição devastadora / Sepsis-related acute respiratory distress syndrome in children with cancer: the respiratory dynamics of a devastating condition

RESUMO Objetivo: Avaliar a evolução clínica e os parâmetros respiratórios de crianças com câncer submetidas à ventilação mecânica que apresentavam síndrome do desconforto respiratório agudo relacionada à sepse. Métodos: Este estudo longitudinal, prospectivo e observacional de coorte com duração de 2 anos incluiu 29 crianças e adolescentes. Dados clínicos, avaliações de gasometria sanguínea e parâmetros ventilatórios foram coletados em quatro momentos diferentes. As flutuações entre as avaliações e as diferenças entre as médias estimadas foram analisadas por meio de modelos lineares mistos, tendo como parâmetro primário (endpoint) a ocorrência de óbito dentro de 28 dias após o início da síndrome do desconforto respiratório agudo. Resultados: Ocorreram 17 óbitos dentro de 28 dias após o início da síndrome do desconforto respiratório agudo, e outros 7 entre 29 e 60 dias. Apenas cinco pacientes sobreviveram por mais de 60 dias. Nove (31%) pacientes faleceram como consequência direta de hipoxemia refratária, e os demais em razão de falência de múltiplos órgãos e choque refratário a catecolaminas. Em 66% das avaliações, o volume corrente demandado para obter saturação de oxigênio igual ou acima de 90% foi superior a 7mL/kg. As médias estimadas de complacência dinâmica foram baixas e similares para sobreviventes e não sobreviventes, porém com inclinação negativa da reta entre a primeira e última avaliações, acompanhada por uma inclinação negativa da reta para volume corrente nos não sobreviventes. Os não sobreviventes tiveram significantemente mais hipoxemia, com relações PaO2/FiO2 que demonstravam médias mais baixas e inclinação negativa da reta nas quatro avaliações. As pressões pico, expiratória e média das vias aéreas demonstraram inclinações positivas na reta para os não sobreviventes, que também apresentaram mais acidose metabólica. Conclusões: Na maioria de nossas crianças com câncer, a sepse e a síndrome do desconforto respiratório agudo evoluíram com deterioração dos índices ventilatórios e progressiva disfunção de órgãos, o que tornou esta tríade praticamente fatal em crianças.

ABSTRACT Objective: To evaluate the clinical course and respiratory parameters of mechanically ventilated children with cancer suffering from sepsis-related acute respiratory distress syndrome. Methods: This 2-year prospective, longitudinal, observational cohort study enrolled 29 children and adolescents. Clinical data, measurements of blood gases and ventilation parameters were collected at four different time points. Fluctuations between measurements as well as differences in estimated means were analyzed by linear mixed models in which death within 28 days from the onset of acute respiratory distress syndrome was the primary endpoint. Results: There were 17 deaths within 28 days of acute respiratory distress syndrome onset and another 7 between 29 - 60 days. Only 5 patients survived for more than 60 days. Nine (31%) patients died as a direct consequence of refractory hypoxemia, and the others died of multiple organ failure and catecholamine-refractory shock. In 66% of the measurements, the tidal volume required to obtain oxygen saturation equal to or above 90% was greater than 7mL/kg. The estimated means of dynamic compliance were low and were similar for survivors and non-survivors but with a negative slope between the first and final measurements, accompanied by a negative slope of the tidal volume for non-survivors. Non-survivors were significantly more hypoxemic, with PaO2/FiO2 ratios showing lower estimated means and a negative slope along the four measurements. Peak, expiratory and mean airway pressures showed positive slopes in the non-survivors, who also had more metabolic acidosis. Conclusions: In most of our children with cancer, sepsis and acute respiratory distress syndrome progressed with deteriorating ventilation indexes and escalating organic dysfunction, making this triad nearly fatal in children.

Bronchiolitis Obliterans Associated with Stevens-Johnson Syndrome: A Case Report

We report a case of bronchiolitis obliterans associated with Stevens-Johnson syndrome. A 59-year-old man presented with respiratory distress that gradually worsened over 3 months. He had been diagnosed with Stevens-Johnson syndrome 3 months before admission. He had no history of previous airway disease. On physical examination, expiratory breathing sounds were not audible, and a chest X-ray revealed a hyperinflated lung. A pulmonary function test indicated a severe obstructive pattern. Computed tomography scans of inspiratory and expiratory phases of respiration showed oligemia and air trapping, and both were more prominent on expiration view than on inspiration view. The pathogenesis of bronchiolitis obliterans associated with Stevens-Johnson syndrome is largely unknown.

Postperfusion lung syndrome: physiopathology and therapeutic options / Síndrome pós-perfusão pulmonar: fisiopatologia e opções terapêuticas

Postperfusion lung syndrome is rare but can be lethal. The underlying mechanism remains uncertain but triggering inflammatory cascades have become an accepted etiology. A better understanding of the pathophysiology and the roles of inflammatory mediators in the development of the syndrome is imperative in the determination of therapeutic options and promotion of patients' prognosis and survival. Postperfusion lung syndrome is similar to adult respiratory distress syndrome in clinical features, diagnostic approaches and management strategies. However, the etiologies and predisposing risk factors may differ between each other. The prognosis of the postperfusion lung syndrome can be poorer in comparison to acute respiratory distress syndrome due to the secondary multiple organ failure and triple acid-base imbalance. Current management strategies are focusing on attenuating inflammatory responses and preventing from pulmonary ischemia-reperfusion injury. Choices of cardiopulmonary bypass circuit and apparatus, innovative cardiopulmonary bypass techniques, modified surgical maneuvers and several pharmaceutical agents can be potential preventive strategies for acute lung injury during cardiopulmonary bypass.

Síndrome pós-perfusão pulmonar é rara, mas pode ser letal. O mecanismo subjacente permanece incerto, mas desencadear cascatas inflamatórias tornou-se uma etiologia aceita. É imperativo uma melhor compreensão da fisiopatologia e os papéis de mediadores inflamatórios no desenvolvimento da síndrome na determinação de opções terapêuticas e de promoção do prognóstico e sobrevida dos pacientes. Síndrome pós-perfusão pulmonar é semelhante à síndrome da angústia respiratória do adulto em características clínicas, métodos diagnósticos e estratégias de gestão. No entanto, as etiologias e fatores de risco predisponentes podem ser diferentes entre si. O prognóstico da síndrome pós-perfusão pulmonar pode ser mais pobres em comparação com síndrome da angústia respiratória aguda, devido à falência de múltiplos órgãos secundária e desequilíbrio ácido-base triplo. Estratégias de gestão atuais centram-se em atenuar reações inflamatórias e impedir lesão pulmonar de isquemia-reperfusão. Escolhas do circuito de circulação extracorpórea e aparelhos, técnicas inovadoras de circulação extracorpórea, manobras cirúrgicas modificadas e vários agentes farmacêuticos podem ser potenciais estratégias preventivas para lesão pulmonar aguda durante a circulação extracorpórea.

The Role of Platelets in Malarial Acute Lung Injury and Acute Respiratory Distress Syndrome: A World of Possibilities.

In recent decades our understanding of platelets’ role in immune response has increased. Traditionally platelets were considered as bleeding-stopping and thrombosis-causing cells. In recent years the platelets’ role in malarial innate and adaptive immune responses is being recognized. Platelets play critical role in pathogenesis of malaria infection leading to variety of outcomes. It is being realized that platelets play dual role in case of malaria (i) by preventing early stage exponential growth of parasitemia (ii) promoting exaggerated immune responses later. Platelets role in pathogenesis of severe and cerebral malaria has been widely studied. However their role in malaria related acute lung injury and respiratory distress has gained less attention. Recently the presence of active megakaryocytes and proplatelets have been explained in human lungs. Simultaneously, the platelets role in pathogenesis of acute lung injury and respiratory distress (ALI/ARDS) was also recognized. This gives a hint that there is a possible association of platelets with malaria related respiratory diseases as well. ALI/ARDS are characterized by lung edema due to increased permeability of the alveolar-capillary barrier and subsequent impairment of arterial oxygenation. In this review we have attempted to establish the importance of role of platelets in malaria related acute lungs injury and malaria acute respiratory distress syndrome and try to explain the underlying mechanism of this process. In ALI/ARDS, including those caused by malaria, platelets participate sequestration to the vascular bundle facilitating the recruitment of immune cells viz. neutrophils. Additionally, they secrete or induce the secretion of chemokines that result into vascular damage.

Clinical Profile of the H1N1 Influenza.

The H1N1 influenza A infection initially pandemic started in Mexico in March 2009 and spread as per WHO phases of pandemic alert all over the world. It was in late march 2009 an outbreak of a respiratory illness and later to proved to be caused by novel swine origin influenza A (S-OIV) identified in Mexico. Aims & Objectives : The aim of the present study was to describe first clinical presentation, various organ damage, treatment outcome duration of hospital stay and mortality and impact on high risk group patients. This is retrospective study hospital based Bharati Vidyapeeth Deemed University Medical College and Hospital, Sangli. Material and Methods: During post-pandemic period in 2010 the patients were admitted in hospitals which were suspected cases of H1N1 influenza “A” infection. 118 cases were studied August 2010 to 31st January 2011. Results : One hundred eighteen (118) patients were admitted in hospital. Of the 118 patients 32 patients were H1N1 positive and 86 patients H1N1 negative. RT- PCR test was done for confirmation of infection. X- Ray chest in positive cases of H1N1 influenza “A” infection bilateral extensive Pneumonititis other organ damage suggestive ECG, STT were changes renal failure common symptoms cough, fever, breathlessness in 28 cases sex-wise and age-wise distribution is not significant. Hospital stay all admitted patients and hospital stay in expired patients p value < 0.00 and < 0.005 highly significant. Statistics – percentage, ratio Chi- square tests used. Conclusion : Mortality in risk (Comorbid condition) with and without risk (ventilator required) The Mortality was 18.50 % more during the winter season (Chilly and cold atmosphere August to October during this season feverable for viability of the virus) significantly mortality is seen in young age group. This infection can be prevented by vaccination. The tablet tamiflu 75 mg 1 BD for 10 days no other adverse effects observed in our study the drug is safe and no resistance was observed.

The behavior and diagnostic utility of procalcitonin and five other inflammatory molecules in critically ill patients with respiratory distress and suspected 2009 influenza a H1N1 infection

OBJECTIVES: During the 2009 influenza A H1N1 pandemic, it became difficult to differentiate viral infections from other conditions in patients admitted to the intensive care unit. We sought to evaluate the behavior and diagnostic utility of procalcitonin, C-reactive protein and four other molecules in patients with suspected 2009 Influenza A H1N1 infection. METHODS: The serum levels of procalcitonin, C-reactive protein, tumor necrosis factor α, interferon γ, interleukin 1β, and interleukin 10 were tested on admission and on days 3, 5, and 7 in 35 patients with suspected 2009 H1N1 infection who were admitted to two ICUs. RESULTS: Twelve patients had confirmed 2009 influenza A H1N1 infections, 6 had seasonal influenza infections, and 17 patients had negative swabs. The procalcitonin levels at inclusion and on day 3, and the C-reactive protein levels on day 3 were higher among subjects with 2009 influenza A H1N1 infections. The baseline levels of interleukin 1b were higher among the 2009 influenza A H1N1 patients compared with the other groups. The C-reactive protein levels on days 3, 5, and 7 and procalcitonin on days 5 and 7 were greater in non-surviving patients. CONCLUSION: Higher levels of procalcitonin, C-reactive protein and interleukin-1β might occur in critically ill patients who had a 2009 H1N1 infection. Neither procalcitonin nor CRP were useful in discriminating severe 2009 H1N1 pneumonia. Higher levels of CRP and procalcitonin appeared to identify patients with worse outcomes.

Coagulopathy as a Prognostic Factor of Acute Lung Injury in Children

The coagulation cascade and inflammatory process are known to be associated with the pathophysiology of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). We retrospectively investigated laboratory values indicating coagulopathy obtained within 24 hr from diagnosis of ALI/ARDS in 79 children who received mechanical ventilation between 2008 and 2009 and their final outcomes. Prothrombin time (PT) (P = 0.001) and activated partial thromboplastin time PTT (APTT) (P = 0.001) were more prolonged in non-survivors than survivors (mean; 1.57 vs 1.33; 63 vs 57). In multivariate analysis with stratification by oxygenation-index ( or = 14.5), prolonged PT (> or = 1.46 international normalized ratio, [INR]) (hazard ratio; 2.043, 1.027-4.064) was associated with lower non-pulmonary-organ-failure-free survival rate (FFS), and prolonged APTT (> or = 50 seconds) (2.062, 1.031-4.121; 2.422, 1.227-4.781) was associated with lower overall survival rate (OS) and lower FFS. In stratification by ventilation-index ( or = 40), prolonged PT (2.232, 1.095-4.540; 2.177, 1.092-4.342) and prolonged APTT (2.574, 1.230-5.386; 3.089, 1.500-6.360) were associated with lower OS and lower FFS. Prolonged PT and APTT are associated with mortality in mechanically ventilated children with ALI/ARDS. We suggest PT and APTT as prognostic factors of ALI/ARDS in children.

Influenza A (H1N1) was not associated with obesity in pregnant women living in Toluca, México / La Influenza A (H1N1) no se asoció con la obesidad en mujeres embarazadas en Toluca, México

Objective The aim was to verify whether being overweight could have played a critical role in cases of mortality caused byinfluenza A (H1N1) in pregnant women. This virus' prevalence was also analyzed among people suffering from acute respiratory disease being attended at the state of Mexico's Autonomous University's medical research centre. Methods The clinical files of women having influenza A (H1N1) attending the Monica Pretelini maternal-perinatal hospital's (HMPMP) intensive care unit in Toluca, Mexico, were reviewed. According to international recommendations, clinical detection of possible new cases of this disease was kept an open as a second step. Results Five women suffering influenza A (H1N1) was attended at HMPMP's intensive care unit during 2009; only one survived. No differences in body mass index were found when comparing the anthropometric characteristics to another group of women affected by acute respiratory diseases; in fact, this parameter was below the limits for being overweight in both cases. No new case of influenza A (H1N1) was found after the first eight months of 2010. Discussion It could not be verified whether being overweight was a factor of higher mortality due to influenza A (H1N1) amongst pregnant women in the state of Mexico. The key to better survival for pregnant women hospitalized with influenza A (H1N1) seemed to be early treatment with oseltamivir. The cases decreased dramatically after the severe wave of the new pandemic due to unknown reasons.

Objetivo Nuestro objetivo fue verificar si en los casos de mortalidad por influenza A (H1N1) en mujeres embarazadas, el sobrepeso tuvo un papel fundamental. También hemos analizado la prevalencia de este virus entre personas con enfermedad respiratoria aguda atendidas en el Centro de Investigación en Ciencias Médicas de la Universidad Autónoma del Estado de México. Métodos Se revisaron los expedientes clínicos de las mujeres con influenza A (H1N1) atendidos en la Unidad de Cuidados Intensivos Obstétricos del Hospital Materno Perinatal, Toluca, México. De acuerdo con las recomendaciones internacionales, como segunda etapa se mantuvo un programa de detección de este virus en la población general. Resultados Hubo cinco embarazadas con influenza A (H1N1), durante el año 2009, de las cuales sólo una sobrevivió. Al comparar las características antropométricas con otro grupo de mujeres afectadas por enfermedades respiratorias agudas no encontramos diferencias en el índice de masa corporal. De hecho, en ambos casos, este parámetro fue inferior a los límites de sobrepeso. Después de los primeros ocho meses del año 2010 no se encontraron nuevos casos de influenza A (H1N1). Discusión No hemos podido verificar que el sobrepeso sea un factor de mayor mortalidad en casos de infección por influenza A (H1N1) entre las mujeres embarazadas del Estado de México. La clave para una mejor supervivencia en mujeres embarazadas hospitalizadas con influenza A (H1N1) parece ser el tratamiento precoz con Oseltamivir. Por razones desconocidas después de la ola severa de la nueva pandemia los casos disminuyeron.

Síndrome do desconforto respiratório agudo comocomplicação de psoríase pustulosa generalizada / Acute respiratory distress syndrome as a complication of generalized pustular psoriasis

Desde 1991, há 8 casos relatados de síndrome da fragilidade capilar pulmonar associada à psoríase pustulosa ou eritrodérmica, induzida ou não pelo uso de acitretina ou sirolimus - um dos casos, fatal. Reportamos um caso de psoríase pustulosa de von Zumbusch em paciente feminina com antecedente de várias internações por quadro semelhante, evoluindo nesta ocasião com acometimento pulmonar e resolução com corticosteroide. A paciente não estava em uso de quaisquer medicações previamente descritas como capazes de precipitar o quadro pulmonar (metotrexate e acitretina). Esta é uma complicação rara associada à psoríase, não descrita em pacientes brasileiros até o momento.

Since 1991, eight cases of pulmonary leak capilary syndrome have been described associated with pustular or erythrodermic psoriasis induced or not by the use of acitretin or sirolimus - being one of the cases, fatal. We report the case of a female patient with diagnosed GPP or von Zumbusch and multiple hospitalizations due to such condition. At that time, the condition was evolving with pulmonary onset and resolution with corticosteroids. The patient was not using any previously described medication that could precipitate pulmonary condition (methotrexate and acitretin). This is a rare complication associated with psoriasis which has not been described in Brazilian patients so far.

Fractured tracheostomy tube migrating into the tracheobronchial tree: A rare complication.

Tracheostomy is a life saving procedure and many patients are discharged with permanent tracheostomy tubes. We report the rare occurrence of a fractured tracheostomy tube migrating into the tracheobronchial tree and highlight the clinical manifestations of this uncommon complication that carries the potential risk of fatal respiratory obstruction.

Entendendo a estrutura microscópica e submicroscópica da barreira alvéolo-capilar na lesão pulmonar aguda / Understanding the microscopic and submicroscopic structure of the alveolar-capillary membrane in acute lung injury

A lesão pulmonar aguda/síndrome do desconforto respiratório agudo (LPA/SDRA) pode ser induzida por diferentes causas. A lesão pulmonar ocorre por efeito direto sobre as células epiteliais pulmonares ou em decorrência de efeito indireto sobre as células endoteliais, onde o dano pulmonar decorre da liberação de mediadores inflamatórios em órgãos distais. Neste artigo, enfatizamos as diferenças microscópicas e submicroscópicas no pulmão envolvido na LPA e SDRA, ambas caracterizadas por intensa resposta inflamatória local com acúmulo de diferentes tipos celulares.O remodelamento do parênquima pulmonar caracterizado por fibroelastogênese ocorre em paralelo com o processo inflamatório. O prognóstico do paciente dependerá da resolução do evento inicial e do balanço entre a intensidade das respostas inflamatória e de remodelamento. Diferentes protocolos tentam modificar ambas as respostas, mas todos com resultados negativos. Postulamos que, para uma melhor compreensão da fisiopatologia da SDRA, diferenças microscópicas e submicroscópicas devem ser consideradas. Logo, para se estabelecer uma conduta clínica mais precisa e melhorar o prognóstico desses pacientes, deve-se considerar a etiologia da LPA/SDRA.

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) can be induced by various causes. Lung injury can occur through direct or indirect effects on the lung epithelial cells, the latter caused by the release of inflammatory mediators in distal organs. In this article, we emphasize the lung microscopy and ultrastructural changes seen in ALI and ARDS, both of which are characterized by an intense inflammatory process with cell infiltration. The lung parenchyma remodeling process is characterized by fibroelastogenesis occurring in parallel with the inflammatory process. The prognosis depends on the resolution of the initial event and on the balance between the inflammatory response and the remodeling process. Although various protocols have been developed in attempts to modify those aspects, none have produced positive results.We postulate that a better understanding of ARDS cannot be gained without taking lung microscopy and ultrastructural analysis of the lung parenchyma into account. Therefore, in order to improve the clinical management and the prognosis of patients with ALI/ARDS, the etiology of the syndrome should be considered.

Efeito de diferentes técnicas de ventilação mecânica sobre o estresse oxidativo pulmonar induzido por lesão pulmonar aguda experimental / Effect of different techniques of mechanical ventilation on pulmonary oxidative stress induced by experimental acute lung lesion

Ventilação mecânica (VM) pode induzir estresse oxidativo pulmonar, o qual desempenha papel importante na lesão pulmonar. Este estudo comparou a ventilação mecânica convencional proterora (VMC) e a ventilação oscilatória de alta frequência (VAF) quanto a oxigenação, estresse oxidativo pulmonar, inflamação e lesão pulmonar histopatológica em modelo de lesão pulmonar aguda (LPA) em coelhos. Coelhos (n = 30) foram ventilados com FiO2 1.0. A lesão pulmonar foi induzida por infusão traqueal de solução salina (30mL/kg, 38 ºC). Os animais foram aleatoriamente distribuidos para compor os seguintes grupos: a) Controle [GC: volume corrente (VT) 6mL/kg, pressão expiratória final positiva (PEEP) 5cmH2O, frequência respiratória (FR) 40 ipm], b) LPA + VMC [GVMC: VT 6ml / kg, PEEP 10cmH2O, FR 40 ipm] e c) LPA + VAF [GVAF: pressão média de vias aéreas (Paw) 14 cmH2O, FR 10Hz]. Estresse oxidativo pulmonar foi avaliado por meio da capacidade antioxidante total, a resposta inflamatória pelo número de leucócitos polimorfonucleares/lavado broncoalveolar/pulmão e o dano histológico pulmonar foi quantificado por um escore. Parâmetros ventilatórios e hemodinâmicos foram registrados a cada 30 minutos. Ambos os grupos com LPA apresentaram piora da oxigenação após a indução da lesão pulmonar...

Critical illness myopathy

Critical illness myopathy [CIM] is a syndrome of widespread muscle weakness and neurological dysfunction which can develop in critically ill patients receiving intensive care. CIM are often distinguished largely on the basis of specialized electrophysiologic testing or muscle and nerve biopsy and its causes are unknown, though they are thought to be a possible neurological manifestation of systemic inflammatory response syndrome usually developing in patients after a brief period of stay in the Intensive Care Unit [ICU]. This case report aims to analyze the Clinical feature, diagnosis and treatment of CIM of 60 years old male case with Chronic Obstructive Lung disease [COPD] admitted to the intensive care. Health professionals working at critical care unit should be aware that any ICU patient may develop CIM

Clinical Analysis of Stercoral Perforation of the Colon / 대한소화기학회지

BACKGROUND/AIMS: A stercoral perforation of the colon (SPC) is a rare, life-threatening disease. The aim of this study was to represent the definition of SPC and help the diagnosis and treatment of this condition. METHODS: We reviewed 92 medical records of patients who underwent operation due to colonic perforation from January 2000 to February 2009 retrospectively. Maurer's diagnostic criteria were used for the diagnosis of SPC. RESULTS: Eight patients (8.7%) were diagnosed as SPC. The age of the patients ranged from 59 to 85 years old. All of the patients were female and had a history of long-standing constipation. Only two patients (25%) were diagnosed as SPC preoperatively. The site of perforation of all patients was sigmoid colon. The methods of operation were Hartmann's procedure (7 cases), and primary repair with sigmoid loop colostomy (1 case). There were one recurrence and two deaths (25%) due to sepsis and multiple organ failure. CONCLUSIONS: SPC should be considered in chronically constipated, and bedridden patients who present with acute abdomen. Hartmann's procedure is the treatment of choice in most situations. Mortality is high but can be minimized with early definitive surgery.
