Forensic Analysis of 72 Cases with Multiple Organ Dysfunction Syndrome Caused by Traffic Accidents / 法医学杂志

Objective To investigate the epidemiological and forensic characteristics of multiple organ dysfunction syndrome （MODS） after severe trauma and explore the reference indexes for determining traumatic MODS. Methods In terms of the number of organs or systems involved in MODS, the number of failures of each organ or system, the first failing organ and the survival time after organ failure, 72 cases of MODS death caused by traffic accidents were retrospectively analyzed. The cases were divided into two groups according to the mean injury severity score （ISS）. The t test was used to analyze the differences in the number of organs or systems involved in MODS in the two groups. Chi-square test was used to analyze the differences in the types of first failing organs and the differences between the two groups in the number of cases of organ or system failure involved in MODS. Wilcoxon signed-rank test was used to analyze the differences between the two groups in survival time of MODS after trauma. Kaplan-Meier survival curve was drawn and Log-Rank test was performed. Results The number of MODS involved organs or systems after trauma in ISS≤35 group was 3-5, and 2-4 in the ISS>35 group （P<0.05）. The cases of MODS organ or system failure after trauma occurred more in brain and lung in the two groups. The first failing organ after trauma was mainly the lung or kidney. The median time of first organ failure after trauma was 2.00 d, the median survival time of MODS after trauma in ISS≤35 group was 6.00 d, and 2.33 d in ISS>35 group （P<0.05）. The survival curve of ISS≤35 group was relatively high and declined gradually, while the survival curve of ISS>35 group was relatively low and the decline was steep （P<0.05）. Conclusion The epidemiological and forensic characteristics of MODS caused by traffic accidents have certain specificity. The ISS and the forensic characteristics of MODS at ISS>35 can be used as reliable reference indexes for evaluation of the causal relationship among trauma, MODS and death.

Disfunção de múltiplos órgãos causada por corpo estranho no esôfago / Multiple organ dysfunction caused by a foreign body in the esophagus

RESUMO Apresentamos o caso de uma paciente de 71 anos de idade admitida à unidade de terapia intensiva clínica em condição de falência de múltiplos órgãos. Após o quarto dia, com aplicação de todas as modalidades de suporte à vida (estímulo com vasopressores, ventilação mecânica, terapia com diálise contínua, terapia com antibióticos de amplo espectro e outras medidas de suporte), dados inespecíficos fornecidos por acompanhante revelaram que a paciente vinha apresentando dificuldade persistente para deglutir líquidos e alimentos sólidos por alguns dias antes da admissão ao hospital. Após a realização de procedimentos adicionais de diagnóstico radiológico e endoscópico, detectou-se a presença de um corpo estranho no esôfago: um fragmento de fio de aço com cerca de 6 cm de comprimento e dobrado ao meio, que havia penetrado a parede do esôfago e se projetava ao nível da sétima vértebra cervical. Conseguimos remover o corpo estranho por via endoscópica sem maiores complicações e, a seguir, estabilizar nossa paciente, com utilização de medidas terapêuticas adicionais, conforme necessário.

ABSTRACT We present the case of a 71-year-old patient who was admitted to the medical intensive care unit in a state of multiple organ dysfunction. After the fourth day of applying all needed life-saving measures (vasopressor stimulation, mechanical ventilation, continuous dialysis treatment, broad spectrum antibiotic therapy, and other supportive measures), nonspecific heteroanamnestic data revealed that the patient had been having a persistent difficulty in swallowing liquids and food for a few days prior to hospital admission. After performing additional radiological and endoscopic diagnostic procedures, a foreign body was detected; a steel wire that had a length of approximately 6cm and was bent in a half had penetrated the esophagus and was projected into the seventh neckline. We managed to evacuate the foreign body endoscopically without further complications, and we stabilized our patient using additional therapeutic measures as needed.

Conclusions: The factors associated with the presentation of multi-organ failure were identified, which made possible the design of a predictive scale of this failure in the patient with secondary diffuse peritonitis(AU)

Hepatitis isquémica fulminante inducida por disfunción cardiaca severa: reporte de caso / Fulminating ischemic hepatitis induced by severe cardiac dysfunction: case report

La hepatitis isquémica es una entidad infrecuente en la práctica clínica diaria con una prevalencia de 0,16 a 0,5% entre los pacientes admitidos en unidad de cuidados críticos, asociado a una mortalidad aproximada en el 60% de los casos. Esta hepatopatía se caracteriza por un incremento rápido y marcado (más de 20 veces el valor normal) del nivel de transaminasas secundario a una hipoperfusión hepática severa y persistente ocasionada por múltiples etiologías, que puede ser transitoria de identificarse y tratar la causa desencadenante oportunamente. A continuación presentamos el caso de un paciente adulto mayor con un cuadro clínico, epidemiológico y bioquímico compatible con hepatitis isquémica secundario a disfunción cardiaca severa.

Ischemic Hepatitis is an uncommon entity in daily clinical practice with a prevalence of 0.16 to 0.5% among patients admitted to a critical care unit, associated with an approximate 60% mortality rate. This liver disease is characterized by a rapid and marked increase (more than 20 times the normal value) of the level of transaminases secondary to a severe and persistent hepatic hypoperfusion caused by multiple etiologies, which may be transient when the triggering cause is timely identified and appropiately treated. The case of an elderly adult patient with a clinical, epidemiological and biochemical profile compatible with ischemic hepatitis secondary to severe cardiac dysfunction is presented below.

Bacteremia por Vibrio cholerae NO-O1/NO-O139 en un paciente cirrótico: Primer reporte de caso en el Perú y revisión de la literatura / Vibrio cholerae NO-O1/NO-O139 bacteremia in a cirrhotic patient: First case report in Peru and literatura review

Vibrio cholerae serogrupo NO-O1/NO-O139 (VCNO) es causa infrecuente de gastroenteritis. Sin embargo, se le asocia a infección extra-intestinal severa en huéspedes inmunocomprometidos, y entre ellas, la bacteremia en pacientes con cirrosis hepática es digna de mención. A continuación, presentamos el caso de una mujer de 58 años, con el diagnóstico de cirrosis hepática de fondo, que desarrolló progresivamente choque séptico, disfunción orgánica múltiple y desenlace fatal al cuarto día de su admisión. Los resultados obtenidos post mortem, de los hemocultivos previamente tomados, aislaron bacilos gram negativos compatibles con Vibrio cholerae. Posteriormente, se identificó el serogrupo NO-O1/NO-O139, a través de aglutinación en placa y PCR negativo para el gen ctxA. El antibiograma mostró susceptibilidad conservada a ampicilina, cloranfenicol, tetraciclina y ciprofloxacino, con resistencia al trimetoprim-sulfametoxazol. El presente caso, descrito en el Hospital Nacional Dos de Mayo, es hasta la fecha, el primer reporte de bacteremia VCNO en el Perú.

Non-O1, non-O139 Vibrio cholerae (NOVC) strains are an uncommon cause of gastroenteritis. However, they have been recently associated with severe extraintestinal infections in immunocompromised hosts. Among them, bacteremia in cirrhotic patients is noteworthy. We present the case of a 58-year-old woman with cirrhosis that developed septic shock, multiple organ failure and died four days after admission. Blood cultures yielded Gram-negative rods identified as Vibrio cholerae. Further serogrouping by slide agglutination and a negative PCR for ctxA gen confirmed the strain to be NOVC. Antimicrobial susceptibility testing showed sensitivity to ampicillin, chloramphenicol, tetracycline and ciprofloxacin; and resistance to trimethoprim-sulfamethoxazole. To the best of our knowledge, this is first report in Peru, described in the Hospital Nacional Dos de Mayo, of NOVC bacteremia.

Tormenta tiroidea asociada a disfunción multiorgánica / Thyroid storm associated with multiorganic dysfunction

La tormenta tiroidea es una condición infrecuente y potencialmente fatal. En la literatura han sido descritas varias presentaciones inusuales de la misma; sin embargo, la disfunción multiorgánica es rara vez vista. Aquí describimos un caso en una mujer de 36 años de edad con enfermedad de Graves subyacente no diagnosticada hasta entonces, quien inició su sintomatología con una tormenta tiroidea. Su score de Burch y Wartofsky fue de 50/140. Desarrolló falla hepática aguda, falla renal aguda, acidosis láctica, falla cardíaca, bicitopenia, coagulopatía y rabdomiolisis. La disfunción multiorgánica se revirtió gracias a la pronta instauración de los esteroides, ciclofosfamida, plasmaféresis y posterior tiroidectomía. La dificultad reside en reconocer las variadas presentaciones de la enfermedad y ofrecer un tratamiento apropiado cuando se enfrenta a las contraindicaciones o las fallas terapéuticas del tratamiento convencional.

Thyroid storm is a rare and potentially fatal condition. Unusual presentations in patients with thyroid storm have been described but multiorganic dysfunction is uncommonly seen. We describe the case of a 36-year-old woman with unknown underlying Graves´s disease who developed thyroid storm. The thyroid storm score of Burch and Wartofsky was 50/140. This was complicated by acute liver failure, acute kidney injury, lactic acidosis, heart failure, bi-cytopenia, coagulopathy and rhabdomyolysis. The severe multiorgan dysfunction was reversed by prompt institution of steroids, cyclophosphamide and plasma exchange before thyroidectomy. Main difficulty lies in recognizing its varied presentations and offering appropriate treatment when physician faces either failure or contraindications of conventional therapy.

Tadalafil: protective action against the development of multiple organ failure syndrome

Abstract Introduction: Multiple organ failure syndrome (MOFS) is a pathology associated to unspecified and severe trauma, characterized by elevated morbidity and mortality. The complex inflammatory MOFS-related reactions generate important ischemia-reperfusion responses in the induction of this syndrome. Nitric oxide elevation, through the activation of cyclic guanosine monophosphate (cGMP), has the potential of counteracting the typical systemic vasoconstriction, and platelet-induced hypercoagulation. Tadalafil would possibly act protectively by reducing cGMP degradation with consequent diffuse vasodilatation, besides reduction of platelet-induced hypercoagulation, thus, preventing multiple organ failure syndrome development. Methods: The experimental protocol was previously approved by an institution animal research committee. Experimental MOFS was induced through the stereotaxic micro-neurosurgical bilateral anterior hypothalamic lesions model. Groups of 10 Wistar rats were divided into: a) Non-operated control; b) Operated control group; c) 2 hours after tadalafil-treated operated group; d) 4 hours after tadalafil-treated operated group; e) 8 hours after post-treated operated group. The animals were sacrificed 24 hours after the neurosurgical procedure and submitted to histopathologic examination of five organs: brain, lungs, stomach, kidneys, and liver. Results: The electrolytic hypothalamic lesions resulted in a full picture of MOFS with disseminated multiple-organs lesions, provoked primarily by diffusely spread micro-thrombi. The treatment with tadalafil 2 hours after the micro-neurosurgical lesions reduced the experimental MOFS lesions development, in a highly significant level (P<0.01) of 58.75%. The treatment with tadalafil, 4 hours after the micro-neurosurgically-induced MOFS lesions, also reduced in 49.71%, in a highly significant level (P<0.01). Finally, the treatment with tadalafil 8 hours after the neurosurgical procedure resulted in a statistically significant reduction of 30.50% (P<0.05) of the experimentally-induced MOFS gravity scores. Conclusion: The phosphodiesterase 5 inhibitor, tadalafil, in the doses and timing utilized, showed to protect against the experimentally-induced MOFS.

Prevalência da falência de múltiplos órgãos na unidade de terapia intensiva pediátrica: comparação dos escores Pediatric Risk of Mortality III e Pediatric Logistic Organ Dysfunction para predição de mortalidade / Prevalence of multiple organ dysfunction in the pediatric intensive care unit: Pediatric Risk of Mortality III versus Pediatric Logistic Organ Dysfunction scores for mortality prediction

RESUMO Objetivo: Avaliar a frequência de falência de múltiplos órgãos primária e o papel da sepse como agente causal em pacientes pediátricos críticos; e calcular e avaliar a precisão dos escores Pediatric Risk of Mortality III (PRISM III) e Pediatric Logistic Organ Dysfunction (PELOD) para predizer os desfechos de crianças em estado crítico. Métodos: Estudo retrospectivo, que avaliou dados de pacientes admitidos entre janeiro a dezembro de 2011 na unidade de terapia intensiva pediátrica do Children's Hospital da Cairo University. Resultados: Dentre os 237 pacientes estudo, 72% tiveram falência de múltiplos órgãos e 45% sepse com falência de múltiplos órgãos. A taxa de mortalidade em pacientes com falência de múltiplos órgãos foi de 73%. Os fatores independentes de risco para óbito foram ventilação mecânica e falência neurológica (OR: 36 e 3,3, respectivamente). O PRISM III foi mais preciso para prever óbito, com qui quadrado no teste de Hosmer-Lemeshow de 7,3 (df = 8; p = 0,5). A área sob a curva foi de 0,723 para o PRISM III e de 0,78 para o PELOD. Conclusão: A falência de múltiplos órgãos esteve associada à elevada mortalidade. A sepse foi sua principal causa. Pneumonia, diarreia e infecções do sistema nervoso central foram as principais causas de sepse. O PRISM III teve melhor calibração do que o PELOD para prognóstico dos pacientes, apesar da elevada frequência da síndrome de falência de múltiplos órgãos.

ABSTRACT Objectives: To assess the frequency of primary multiple organ failure and the role of sepsis as a causative agent in critically ill pediatric patients; and calculate and evaluate the accuracy of the Pediatric Risk of Mortality III (PRISM III) and Pediatric Logistic Organ Dysfunction (PELOD) scores to predict the outcomes of critically ill children. Methods: Retrospective study, which evaluated data from patients admitted from January to December 2011 in the pediatric intensive care unit of the Children's Hospital of the University of Cairo. Results: Out of 237 patients in the study, 72% had multiple organ dysfunctions, and 45% had sepsis with multiple organ dysfunctions. The mortality rate in patients with multiple organ dysfunction was 73%. Independent risk factors for death were mechanical ventilation and neurological failure [OR: 36 and 3.3, respectively]. The PRISM III score was more accurate than the PELOD score in predicting death, with a Hosmer-Lemeshow X2 (Chi-square value) of 7.3 (df = 8, p = 0.5). The area under the curve was 0.723 for PRISM III and 0.78 for PELOD. Conclusion: A multiple organ dysfunctions was associated with high mortality. Sepsis was the major cause. Pneumonia, diarrhea and central nervous system infections were the major causes of sepsis. PRISM III had a better calibration than the PELOD for prognosis of the patients, despite the high frequency of the multiple organ dysfunction syndrome.

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.

Mild hypothermia may offer some improvement to patients with MODS after CBP surgery

ABSTRACT Objective: To summarize the effect of mild hypothermia on function of the organs in patients with multiple organ dysfunction syndrome after cardiopulmonary bypass surgery. Methods: The patients were randomly divided into two groups, northermia group (n=71) and hypothermia group (n=89). We immediately began cooling the hypothermia group when test results showed multiple organ dysfunction syndrome, meanwhile all patients of two groups were drawn blood to test blood gas, liver and kidney function, blood coagulation function, and evaluated the cardiac function using echocardiography from 12 to 36 hours. We compared the difference of intra-aortic balloon pump, extracorporeal membrane oxygenation rate and mortality within one month after intensive care unit admission. Results: Among the 160 patients, 36 died, 10 (11.24%) patients were from the hypothermia group and 26 (36.6%) from the northermia group (P <0.05). In northermia group, 45 (63.38%) patients used intra-aortic balloon pump and 4 (5.63%), extracorporeal membrane oxygenation; in hypothermia group, 35 (39.32%) patients used intra-aortic balloon pump and 2 (2.25%), extracorporeal membrane oxygenation（ P <0.05). The patients' heart rate decreased significantly in the hypothermia group. The heart rate of hypothermia group is significantly slower than the northermia group at the 36th hour (P <0.05). But the mean arterial pressure of hypothermia group is significantly higher than the northermia group at the 36th hour (P <0.05). In hypothermia group, PO2, SvO2 and lactate were improved significantly compared to pre-cooling (P <0.05), and they were significantly better than the northermia group at the 36th hour (P <0.05%). Prothrombin time and activated partial thromboplastin time have no significantly difference between the two groups (P >0.05). But the platelet count has significantly difference between the two groups at the 36th hour (P <0.05). The aspartate transaminase, alanine transaminase and creatinine were improved significantly in the hypothermia group, and they were significantly better than the northermia group (P <0.05). Conclusion: Mild hypothermia is feasible and safe for patients with multiple organ dysfunction syndrome after cardiopulmonary bypass surgery.

Doença de Haff complicada por falência de múltiplos órgãos após ingestão de lagostim: estudo de caso / Haff disease complicated by multiple organ failure after crayfish consumption: a case study

A doença de Haff é uma síndrome que consiste de rabdomiólise não explicada. Pacientes que apresentam a doença de Haff relatam ter ingerido pescado nas últimas 24 horas antes do início da doença. A maioria dos pacientes sobrevive apresentando breve recuperação. O presente artigo é o primeiro relato de doença de Haff complicada por falência de múltiplos órgãos após ingestão de lagostim. Um homem chinês de 66 anos de idade ingeriu lagostim cozido na noite de 23 de junho de 2013. Chegou ao hospital 2 dias mais tarde, sendo admitido à unidade de terapia intensiva. Após a admissão, o paciente recebeu o diagnóstico de doença de Haff complicada por falência de múltiplos órgãos. Apesar dos tratamentos de suporte e sintomático, a condição do paciente deteriorou, vindo o mesmo a falecer em consequência da doença. A doença de Haff é uma rara síndrome clínica que é, às vezes, mal diagnosticada. O diagnóstico precoce e o tratamento adequado são essenciais para prevenir a progressão para falência de múltiplos órgãos.

Haff disease is a syndrome consisting of unexplained rhabdomyolysis. Patients suffering from Haff disease report having eaten fish within 24 hours before the onset of illness. Most patients survive and recover quickly. The present study is the first report of Haff disease complicated by multiple organ failure after crayfish consumption. A 66-year-old Chinese man ate cooked crayfish on the night of June 23, 2013. He arrived at our hospital 2 days later and was admitted to the intensive care unit. After admission, the patient was diagnosed with Haff disease complicated by multiple organ failure. Despite supportive and symptomatic treatments, the condition of the patient deteriorated, and he died due to his illness. Haff disease is a rare clinical syndrome that is sometimes misdiagnosed. Early diagnosis and proper treatment are essential to prevent progression to multiple organ failure.

Efecto del tratamiento antibiótico inicial adecuado sobre la mortalidad en pacientes en estado crítico con bacteriemia por Pseudomonas aeruginosa / Effect of adequate initial antimicrobi al therapy on mortality in critical patients with Pseudomonas aeruginosa bacteremia

Introducción. La bacteriemia es una de las infecciones hospitalarias de mayor mortalidad, especialmente en las unidades de cuidados intensivos, donde es más frecuente. Pseudomonas aeruginosa es uno de los causantes de bacteriemia más agresivos. Objetivo. Evaluar la asociación entre el tratamiento antibiótico inicial y la mortalidad hospitalaria en estos pacientes. Materiales y métodos. Se trata de un estudio de cohorte retrospectivo multicéntrico realizado entre 2005 y 2008. Se consideró tratamiento adecuado aquel iniciado en las primeras 48 horas del diagnóstico que incluyera, al menos, una dosis de antibiótico intravenoso al que P. aeruginosa fuera sensible y hubiera sido suministrado en la dosis y frecuencia recomendadas. El desenlace principal fue la mortalidad hospitalaria en un lapso de 30 días. Se hizo pareo según grado de exposición usando índices de propensión y, posteriormente, análisis paramétrico de supervivencia. Resultados. Se incluyeron 164 pacientes. La mediana de edad y la clasificación del APACHE II ( Acute Physiology and Chronic Health Evaluation II ) fue de 56 y 13, respectivamente. Se identificó la fuente de la bacteriemia en 68,3 % de los casos, y la más frecuente fue el tracto respiratorio; 44 % de los pacientes recibió tratamiento inadecuado, y la resistencia bacteriana fue la principal variable asociada. La proporción de incidencia de sepsis grave, choque séptico, falla orgánica múltiple y muerte en el lapso de 30 días fue de 67,7, 50, 41,5 y 43,9 %, respectivamente. El tratamiento adecuado se asoció a una prolongación del tiempo hasta el evento (razón de tiempo ajustada, 2,95, IC 95%, 1,63 a 5,33). Conclusión. El tratamiento antibiótico inicial adecuado es un factor protector contra la mortalidad hospitalaria en pacientes con bacteriemia por P. aeruginosa .

Introduction: Among hospital-acquired infections, bacteremia is one of the leading causes of mortality worldwide, especially among intensive care unit patients, where it is more frequent. Pseudomonas aeruginosa is one of the most aggressive agents causing bacteremia. Objective: To evaluate the association between initial antimicrobial therapy and hospital mortality in these patients. Materials and methods: A multicenter and retrospective cohort study was conducted between 2005 and 2008. Antimicrobial therapy was considered adequate if it included at least one intravenous antibiotic to which the P. aeruginosa isolate was susceptible in vitro, was administered at the recommended dose and frequency for bacteremia, and initiated within the first 48 hours from diagnosis. The main outcome was 30-day hospital mortality. Patients were paired according to exposure level using propensity score matching, and then a parametric survival model was fitted. Results: One hundred and sixty four patients were included. Median age and the APACHE II score were 56 and 13, respectively. The source of bacteremia was identified in 68.3 % of cases, the respiratory tract being the most frequent. Forty-four percent of patients received inadequate therapy, with bacterial resistance as the main associated variable. The incidence of severe sepsis, septic shock, multiple organ failure and death within the first 30 days was 67.7, 50, 41.5 and 43.9%, respectively. Adequate therapy was associated with a longer time to the event (adjusted time ratio, 2.95, 95% CI, 1.63 to 5.33). Conclusion: Adequate initial antimicrobial therapy is a protective factor against hospital mortality in patients with P. aeruginosa bacteremia.

Falla multiorgánica asociada a hipertermia en una lactante con síndrome de Prader-Willi. caso clínico / Multiorgan failure associated with hyperthermia in an infant with Prader-Willi syndrome. Case report

El golpe de calor es una emergencia médica y se debe entender como una forma de hipertermia asociada a una respuesta inflamatoria sistémica, que ocasiona falla multiorgánica y en la cual la disfunción del sistema nervioso central es predominante. Si no es tratada precozmente, puede ocasionar una alta mortalidad. El síndrome de Prader-Willi es un trastorno genético multisistémico secundario a una anormalidad en el brazo largo del cromosoma 15 (15q11-q13), caracterizado por hipotonía central neonatal, retraso del desarrollo psicomotor, hipogonadismo, hiperfagia y obesidad. Estos pacientes son proclives a presentar problemas de termorregulación. Se comunica el caso de una lactante de 5 meses en quien se estableció el diagnóstico de síndrome de Prader-Willi en el curso de un episodio febril sin foco conocido, que evolucionó con falla multiorgánica y rabdomiólisis secundaria a la hipertermia.

Heat stroke is a medical emergency characterized primarily by an elevated core temperature associated with a systemic inflammatory response, which causes multiple organ dysfunction in which encephalopathy predominates. If it is not early treated has high mortality. The Prader-Willi syndrome is a multisystem genetic disorder secondary to an abnormality in long arm chromosome 15 (15q11-q13), characterized by neonatal central hypotonia, developmental delay, hypogonadism, hyperphagia and obesity. These patients are susceptible to developing thermoregulatory problems. We report the case of a 5-month-old infant, in whom a diagnosis of Prader-Willi syndrome was established in the course of a febrile episode without known focus, who developed multiorganic failure and rhabdomyolysis secondary to hyperthermia.

Intra-Abdominal Pressure in the Early Phase of Severe Acute Pancreatitis: Canary in a Coal Mine? Results from a Rigorous Validation Protocol

BACKGROUND/AIMS: Intra-abdominal hypertension (IAH) is being increasingly reported in patients with severe acute pancreatitis (SAP) with worsened outcomes. The present study was undertaken to evaluate intra-abdominal pressure (IAP) as a marker of severity in the entire spectrum of acute pancreatitis and to ascertain the relationship between IAP and development of complications in patients with SAP. METHODS: IAP was measured via the transvesical route by measurements performed at admission, once after controlling pain and then every 4 hours. Data were collected on the length of the hospital stay, the development of systemic inflammatory response syndrome (SIRS), multiorgan failure, the extent of necrosis, the presence of infection, pleural effusion, and mortality. RESULTS: In total, 40 patients were enrolled and followed up for 30 days. The development of IAH was exclusively associated with SAP with an APACHE II score > or =8 and/or persistent SIRS, identifying all patients who were going to develop abdominal compartment syndrome (ACS). The presence of ACS was associated with a significantly increased extent of pancreatic necrosis, multiple organ failure, and mortality. The mean admission IAP value did not differ significantly from the value obtained after pain control or the maximum IAP measured in the first 5 days. CONCLUSIONS: IAH is reliable marker of severe disease, and patients who manifest organ failure, persistent SIRS, or an Acute Physiology and Chronic health Evaluation II score > or =8 should be offered IAP surveillance. Severe pancreatitis is not a homogenous entity.

Falla orgánica múltiple por estrongiloidiasis diseminada: Comunicación de un caso / Multiple-organ dysfunction caused by dissemination of Strongyloides stercoralis infection: A case report

We report here the case of a 50-year-old male patient, from a rural setting, with past history of alcoholism. He was admitted in the Intensive Care Unit due to a worsening health status after a febrile syndrome of 25 days. In addition, he had diarrhea, intense muscle ache predominantly on upper extremities and abdomen, weight loss, confusion, seizures, psychomotor agitation, tachycardia, tachipnea, anuria, septic shock, coma, and multiple-organ dysfunction syndrome. The hyperinfection syndrome caused by Strongyloides stercoralis was suspected because of severe eosinophilia (52 percent of peripheral blood leukocytes). This diagnosis was verified by the parasitological examination of stool samples by direct wet mount and Baermann techniques. Treatment with thiabendazole at 25 mg/kg per day was started, as well as cefepime, vasoactive drugs, artificial mechanic ventilation, and hemodialysis. The patient died 12 hours after admission, probably due to secondary infection with Escherichia coli.

Se presenta el caso de un paciente masculino, de 50 años, con antecedentes de alcoholismo, procedente de área rural, que ingresó en la Unidad de Cuidados Intensivos por agravamiento de su estado general después de un síndrome febril de 25 días de evolución, presentando shock séptico, coma y falla orgánica múltiple. Se sospechó un síndrome de hiperinfección por Strongyloides stercoralis ante la presencia de una eosinofilia importante (52%), diagnóstico que fue confirmado con el examen parasitológico de las heces. Se inició tratamiento con tiabendazol a 25 mg/ kg al día, cefepima, fármacos vasoactivos, ventilación mecánica y hemodiálisis. Falleció 12 horas después del ingreso, posiblemente a causa de una infección secundaria por Escherichia coli.
