Incidencia de infección en una cohorte histórica del registro nacional de las 1738 artroplastias de cadera operadas por artrosis en 2014 en Uruguay / Incidence of infection in a historical cohort from the national registry of 1738 hip arthroplasties operated for osteoarthritis in 2014 in Uruguay

Introducción: Las infecciones de artroplastia total de cadera tienen una incidencia baja, pero cuando suceden generan un problema sanitario no solo para el paciente, sino también para el sistema de salud. Las mismas pueden generar dolor, disminución de la capacidad funcional, pobre calidad de vida, múltiples cirugías, y en ocasiones, la muerte. Objetivos: Evaluar la incidencia nacional de infecciones en las artroplastias primarias de cadera operadas por artrosis en el 2014 en Uruguay, y los factores de riesgo vinculados al paciente, medio ambiente y acto quirúrgico, incluido el abordaje quirúrgico. Métodos: Estudio observacional analítico de todos los pacientes operados por artrosis. Se selecciona una muestra aleatoria de 633 pacientes, representativa de las 1738 artroplastias realizadas en Uruguay durante el año 2014. Mediante entrevista telefónica y revisión de historias clínicas se identificaron los pacientes con infección profunda del sitio quirúrgico. Se estimó la incidencia de infección y se realizó un análisis uni- multivariado mediante regresión logística para identificar factores asociados a la infección periprotésica profunda. Resultados: Se presentaron 8 infecciones, con una incidencia de 1,21 por ciento (IC 95 por ciento 0,59 ­ 2,20) en la población general. Los factores asociados a la infección protésica con significancia estadística fueron: a) IMC ≥ 35, p= 0,006; b) procedencia de Montevideo 2,07 por ciento (1,03 ­ 4,11) p= 0,031; c) procedencia del subsector privado 1,47 por ciento (0,77 ­ 2,78) p= 0,009; d) centro quirúrgico donde se realizó la cirugía 4,3 % (1,6 ­ 10,9) p= 0,03, e) uso de cemento con antibiótico 1,59 por ciento (0,65 ­ 3,25) p= 0,034. Se presentó sospecha de infección en 6 de 8 pacientes, en los primeros 30 días postoperatorios; a 7 de 8 pacientes se les realizó limpieza quirúrgica y solo a 1 de 8 pacientes se le realizó la revisión protésica definitiva. Conclusiones: La incidencia de infección en cirugía protésica electiva de cadera por artrosis en el Registro Nacional de Uruguay, fue similar a lo publicado en la bibliografía. De las variables frecuentemente citadas como incidentales en esta complicación, solo el índice de masa corporal fue asociado en esta serie. Llaman la atención las asociaciones dependientes de la procedencia, nivel socioeconómico y centro quirúrgico. Los resultados respecto al uso de cemento con antibiótico deben ser evaluados en estudios futuros(AU)

Introduction: Total hip arthroplasty infections have a low incidence, but when they occur they generate health problems for the patient, and for the health system. They can cause pain, decreased functional capacity, poor quality of life, multiple surgeries, and sometimes death. Objectives: To evaluate the national incidence of infections in primary hip arthroplasties operated for osteoarthritis in 2014, and the risk factors related to the patient, the environment and the surgical act, including the surgical approach. Methods: Analytical observational study of all patients operated on for osteoarthritis. A random sample of 633 patients was selected, representative of 1738 arthroplasties performed in Uruguay in 2014. Through a telephone interview and review of medical records, patients with deep infection of the surgical site were identified. The incidence of infection was estimated and univariate and multivariate analysis was performed using logistic regression to identify factors associated with deep periprosthetic infection. Results: There were 8 infections, with an incidence of 1.21 percent (95 percent CI 0.59 - 2.20) in the general population. The statistically significant factors associated with prosthetic infection were: a) BMI ≥ 35, p = 0.006; b) origin of Montevideo 2.07 percent(1.03 - 4.11) p = 0.031; c) origin of the private subsector 1.47 percent (0.77 - 2.78) p = 0.009; d) surgical center where the surgery was performed 4.3 percent(1.6 - 10.9) p = 0.03, e) use of cement with antibiotic 1.59 percent(0.65 - 3.25) p = 0.034. Suspicion of infection was presented in 6 of 8 patients, in the first 30 postoperative days; 7 of 8 patients underwent surgical cleaning and only 1 of 8 patients underwent final prosthetic revision. Conclusions: The incidence of infection in elective prosthetic hip surgery for osteoarthritis in the Uruguayan National Registry was similar to that published in the literature. Body mass index was the only variable associated as incidental to this complication in this series, out of those frequently cited. The associations depending on the origin, socioeconomic level and surgical center are striking. The results regarding the use of cement with antibiotics should be evaluated in future studies(AU)

Tuberculosis pulmonar asociada a Infliximab: a propósito del primer caso reportado en Cuba / Infliximab-associated pulmonary tuberculosis: regarding the first case reported in Cuba

La terapia con fármacos antagonistas del factor de necrosis tumoral alfa ha sido beneficiosa en el tratamiento de varias enfermedades como las del tejido conectivo e inflamatorias del intestino, pero no está exenta de riesgos. Las principales complicaciones de estas drogas inmunosupresoras son las infecciones, y la tuberculosis pulmonar es una de las principales afecciones, que se pueden observar en los pacientes con este tipo de tratamiento.Se presentó una mujer de 31 años, atendida en el Hospital Clínico Quirúrgico Hermanos Ameijeiras, La Habana, Cuba, con antecedentes de colitis ulcerativa, que hace 3 meses recibe terapia con Infliximab. Acude al hospital por referir 4 días previos al ingreso, fiebre de 390 C dos veces al día, acompañándose de cefalea, pérdida del apetito y dolor en la región perineal. Se le realizó radiografía de tórax, donde se describe radiopacidad heterogénea que va desde el cuerno superior del hilio derecho hasta planos axilares, en la tomografía axial de tórax reportan consolidación en segmento anterior del lóbulo superior derecho con presencia de broncograma aéreo y en el lavado bronquial microbiológico para bacilos ácido-alcohol resistentes se informó codificación 8, positivo a Mycobacterium tuberculosis. El diagnóstico preciso de tuberculosis relacionada con el uso de fármacos antagonistas del factor de necrosis tumoral alfa requiere un alto índice de sospecha y una investigación detallada. Existe un alto grado de complejidad diagnóstica, por la existencia de un amplio espectro clínico y la necesidad de excluir otras enfermedades.

Tumor necrosis factor alpha antagonist drug therapy has been beneficial in the treatment of several diseases such as connective tissue and inflammatory bowel diseases, but it is not without risks. The main complications of these immunosuppressive drugs are infections, and pulmonary tuberculosis is one of the main conditions, which can be observed in patients with this type of treatment. A 31-year-old woman, treated at the Hermanos Ameijeiras Clinical Surgical Hospital, Havana, Cuba, with a history of ulcerative colitis, who has been receiving Infliximab therapy for 3 months, presented. He went to the hospital for referring 4 days prior to admission, a fever of 390 C twice a day, accompanied by headache, loss of appetite and pain in the perineal region. A chest X-ray was performed, which described heterogeneous radiopacity that goes from the upper horn of the right hilum to axillary planes, in the chest axial tomography they report consolidation in the anterior segment of the right upper lobe with the presence of air bronchogram and in the bronchial lavage microbiological for acid-fast bacilli coding 8, positive for mycobacterium tuberculosis was reported. Accurate diagnosis of tuberculosis related to the use of tumor necrosis factor alpha antagonist drugs requires a high index of suspicion and detailed investigation. There is a high degree of diagnostic complexity, due to the existence of a wide clinical spectrum and the need to exclude other diseases.

Odontogenic Infection and dental Pain negatively impact Schoolchildrens Quality of Life / Infecção odontogênica e odontalgia impactam negativamente a qualidade de vida de crianças escolares

ABSTRACT The aim of this study is to assess the prevalence of odontogenic infection in lowincome Brazilian schoolchildren and evaluate its association with the subjective variables of oral healthrelated quality of life and dental pain. In this crosssectional study, 230 schoolchildren aged eight to ten years old underwent a clinical oral survey in which the DMFT/dmft and PUFA/pufa indexes were measured. Afterward, children responded individually to the Child Perceptions Questionnaire (CPQ810) and selfreports of dental pain were collected. Data were statistically analyzed using MannWhitney or KruskalWallis test with a posttest by Dunn's and Pearson correlation. Of the children evaluated, 42.6% had odontogenic infection and 80% reported experiencing dental pain. Children's age (p = 0.034) and past experience of dental pain (p < 0.002) were associated with odontogenic sepsis, in addition to impairment of their emotional wellbeing (p = 0.008), social welfare (p = 0.009) and overall impact on quality of life (p = 0.019). Toothache intensity (p < 0.001), frequency (p < 0.001) and duration (p < 0.001) were correlated to the overall impact on children's quality of life. The prevalence of odontogenic infection remains high among lowincome Brazilian schoolchildren. Pediatric infection and its related pain induce not only various biological disorders but also impair children's selfperception of quality of life.

RESUMO O objetivo deste estudo foi avaliar a prevalência de infecção odontogênica em crianças escolares brasileiras de baixa renda e analisar a sua associação com as variáveis subjetivas da autopercepção de qualidade de vida relacionada à saúde bucal e dor dentária. Neste estudo transversal, 230 crianças escolares com 8 a 10 anos de idade realizaram exame clínico bucal no qual os índices CPOD/ ceod e PUFA/pufa foram mensurados. Com isso, as crianças responderam individualmente ao Child Perceptions Questionnaire (CPQ810) e relatos de dor dentária foram coletados. Os dados foram estatisticamente analisados utilizandose o teste MannWhitney ou KruskalWallis, com posterior teste da correlação de Dunn e Pearson. Dentre as crianças examinadas, 42,6% apresentavam infecção odontogênica e 80% reportou experiência de dor dentária. A idade (p=0,034) e experiência de dor dentária (p<0,002) das crianças foram associadas à infecção odontogênica, bem como o seu bemestar emocional (p=0,008) e social (p=0,009) e impacto geral na qualidade de vida (p=0,019). Além disso, a intensidade (p<0,001), frequência (p<0,001) e duração (p<0,001) da odontalgia foram correlacionadas com o impacto geral na qualidade de vida da criança. A prevalência de infecção odontogênica permanece elevada em crianças escolares brasileiras. Infecção pediátrica e sua dor relacionada induzem não apenas diversas desordens biológicas, mas também afetam negativamente a autopercepção de qualidade de vida das crianças.

Emphysematous gastritis due to Sarcina ventriculi infection in a diabetic liver-kidney transplant recipient

Emphysematous gastritis (EG) is a rare and potentially lethal process caused by invasive, gas-producing bacteria leading to inflammation and gas dissection of the stomach. The most common etiologic agents are Clostridium infections, but other organisms, including enterobacteria, staphylococcus, and fungi have also been identified. We report the first case of EG due to Sarcina ventriculi in a solid organ transplant recipient, who presented with epigastric pain and vomiting. The patient had a history of type 1 diabetes mellitus (DM) with recurrent episodes of ketoacidosis and systemic diabetic complications, including severe gastroparesis. CT scan studies demonstrated EG with venous air, and endoscopy showed severe gastritis and ulcerations. In the gastric biopsies, abundant Sarcina ventriculi were noted in areas of mucosal/submucosal necrosis. Antibiotic treatment was instituted at admission, and subsequent endoscopy demonstrated the disappearance of Sarcina, with some improvement of the gastric inflammation; however, the patient developed septic shock with multiorgan failure and expired. This case highlights the need to consider other infectious etiologies in transplant patients, in addition to the well-known opportunistic infections.

Predictive factors of lethality and complications of deep fascial space infections of the neck / Fatores preditivos de letalidade e complicações das infecções dos espaços fasciais profundos do pescoço

ABSTRACT Objective: to identify predictive factors for lethality and complications of deep fascial space infections of the neck (DFSIN), establishing an early and aggressive treatment in the neck before the progression to descending mediastinitis. Methods: we retrospectively analyzed 133 cases of DFSIN treated at Discipline of Head and Neck Surgery of the Medicine School of Santa Casa de Misericórdia de São Paulo. We accessed demographic characteristics, associated diseases, clinical presentation, laboratorial tests, length of hospital stay, number of involved anatomic neck spaces, intra-operative and microbiology findings. We analyzed these data using logistic regression to predict DFSIN lethality and life threatening complications (mediastinitis, septic shock, pneumonia, pleural empyema, skin necrosis). Results: lethality and complication ratios were 9% and 50.3%, respectively. The logistic regression model showed that patients with septic shock were more likely to have progression to death (p < 0.001) and, the presence of more than two involved neck spaces (p < 0.001) and older individuals (p = 0.017) were more likely to have complicated deep neck infections. Descending necrotizing mediatinitis increased the lethality ratio by 50%, and was associated to necrotizing fasciitis (p=0.012) and pleural empyema (p<0.001). Conclusion: septic shock is a lethal predictive factor and age as well as more than two involved neck spaces are the predictive factors for complications. Necrotizing fasciitis is an important factor for complications and death. Therefore, its surgical treatment must be more aggressive. Descending mediastinitis has a high lethal rate and the successful treatment is based on early diagnosis and aggressive surgical approach.

RESUMO Objetivo: identificar os fatores preditivos de letalidade e complicações associados às infecções dos espaços fasciais profundos do pescoço, com intuito de estabelecer tratamento mais precoce antes de evolução para a mediastinite. Métodos: estudo retrospectivo de 133 casos, tratados na Disciplina de Cirurgia de Cabeça e Pescoço da Faculdade de Ciências Médicas da Santa Casa de São Paulo. Por meio da análise de regressão logística, estes dados foram estudados para a predição de letalidade e complicações graves (mediastinite, choque séptico, empiema pleural, pneumonia e necrose de pele). Resultados: a taxa de letalidade identificada foi de 9% e, de complicações de 50,3%. Identificou-se como fator preditivo de letalidade, a presença de choque séptico (p<0,001) e, para o ocorrência de complicações, a idade (p=0,017) e o acometimento de mais de dois espaços anatômicos (p<0,001). A ocorrência de mediastinite descendente necrosante esteve associada à presença de fasciíte necrosante (p=0,012) e empiema pleural (p<0,001). Conclusão: o fator preditivo de letalidade foi a presença de choque séptico e, para ocorrência de complicações graves, a idade e/ou a presença de mais de dois espaços anatômicos acometidos pela infecção. A fasciíte necrosante é fator importante para ocorrência de complicações e morte. Nestes casos, a conduta cirúrgica deve ser mais agressiva. A mediastinite descendente apresenta taxa de letalidade alta e o sucesso no tratamento está no diagnóstico precoce e na intervenção cirúrgica agressiva.

Incidence and risk factors for major infections in hospitalized children with nephrotic syndrome / Incidência e fatores de risco para infecções graves em crianças hospitalizadas com síndrome nefróticas

ABSTRACT Introduction: Children with nephrotic syndrome are at increased risk of infections because of disease status itself and use of various immunosuppressive agents. In majority, infections trigger relapses requiring hospitalization with increased risk of morbidity and mortality. This study aimed to determine the incidence, spectrum, and risk factors for major infections in hospitalized children with nephrotic syndrome. Methods: All consecutive hospitalized children between 1-12 years of age with nephrotic syndrome were enrolled in the study. Children with acute nephritis, secondary nephrotic syndrome as well as those admitted for diagnostic renal biopsy and intravenous cyclophosphamide or rituximab infusion were excluded. Results: A total of 148 children with 162 admissions were enrolled. Incidence of major infections in hospitalized children with nephrotic syndrome was 43.8%. Peritonitis was the commonest infection (24%), followed by pneumonia (18%), urinary tract infection (15%), and cellulitis (14%), contributing with two thirds of major infections. Streptococcus pneumoniae (n = 9) was the predominant organism isolated in children with peritonitis and pneumonia. On logistic regression analysis, serum albumin < 1.5gm/dL was the only independent risk factor for all infections (OR 2.6; 95% CI, 1.2-6; p = 0.01), especially for peritonitis (OR 29; 95% CI, 3-270; p = 0.003). There were four deaths (2.5%) in our study, all due to sepsis and multiorgan failure. Conclusions: Infection remains an important cause of morbidity and mortality in children with nephrotic syndrome. As Pneumococcus was the most prevalent cause of infection in those children, attention should be paid to the pneumococcal immunization in children with nephrotic syndrome.

RESUMO Introdução: Crianças com síndrome nefrótica apresentam maior risco de infecções devido ao próprio status da doença e ao uso de vários agentes imunossupressores. Em grande parte, as infecções desencadeiam recidivas que exigem hospitalização, com risco aumentado de morbidade e mortalidade. Este estudo teve como objetivo determinar a incidência, o espectro e os fatores de risco para infecções graves em crianças hospitalizadas com síndrome nefrótica. Métodos: Todas as crianças hospitalizadas consecutivamente entre 1 e 12 anos de idade com síndrome nefrótica foram incluídas no estudo. Crianças com nefrite aguda, síndrome nefrótica secundária, bem como aquelas admitidas para biópsia renal diagnóstica e infusão intravenosa de ciclofosfamida ou rituximabe foram excluídas. Resultados: Foram cadastradas 148 crianças com 162 internações. A incidência de infecções graves em crianças hospitalizadas com síndrome nefrótica foi de 43,8%. A peritonite foi a infecção mais comum (24%), seguida por pneumonia (18%), infecção do trato urinário (15%) e celulite (14%), contribuindo com dois terços das principais infecções. Streptococcus pneumoniae (n = 9) foi o organismo predominantemente isolado em crianças com peritonite e pneumonia. Na análise de regressão logística, a albumina sérica < 1,5gm / dL foi o único fator de risco independente para todas as infecções (OR 2,6; 95% CI, 1,2-6; p = 0,01), especialmente para peritonite (OR 29; IC95% 3 -270, p = 0,003). Houve quatro mortes (2,5%) em nosso estudo, todas devido a sepse e falência de múltiplos órgãos. Conclusões: A infecção continua sendo uma importante causa de morbimortalidade em crianças com síndrome nefrótica. Como o Pneumococo foi a causa mais prevalente de infecção nessas crianças, deve-se atentar para a imunização pneumocócica em crianças com síndrome nefrótica.

Factores de riesgo asociados a infección de fracturas expuestas por proyectil de arma de fuego / Associated risk factors for infection in open fractures by firearms

Resumen: Antecedentes: La introducción de armas de fuego ha incrementado las muertes, asesinatos y suicidios. Las lesiones por proyectil de arma de fuego (PAF) afectan cada vez más a poblaciones civiles (500,000 lesiones anualmente) y es la segunda causa de muerte en jóvenes. La mitad requiere tratamiento de fracturas (45%), acompañado de reportes de 6% que desarrollaron una infección profunda. Material y métodos: Estudio retrospectivo, observacional y transversal en cuatro hospitales de la Secretaría de Salud de la CDMX de la frecuencia de infección en fracturas expuestas por PAF y si existe algún otro factor que acompañe a la infección. Resultados: Se encontraron en la revisión de los expedientes de los cuatro hospitales a 67 pacientes, hombres, con una incidencia de infecciones de 4.5%, al analizar los factores de riesgo éstos no presentaron asociación significativa. Discusión: Ningún factor de riesgo posee significancia estadística de que se presente algún proceso infeccioso, probablemente por un buen tratamiento inicial.

Abstract: Background: The introduction of firearms has increased deaths, assassinations and suicides. Firearm projectile injuries (PAF) increasingly affect civilian populations (500,000 injuries annually), it is the second cause of death in young people. Half required fracture treatment (45%), accompanied by reports of 6% who developed a deep infection. Material and methods: Retrospective, observational, cross-sectional study in four hospitals of the Secretary of Health of CDMX of the frequency of infection in fractures exposed by PAF and if there is any other factor that is associated with the infection. Results: In the review of the files of the four hospitals, 67 patients were found, men, with an incidence of infections of 4.5%, when analyzing the risk factors these did not present a significant association. Discussion: No risk factor has statistical significance for any infectious process to occur, probably due to a good initial treatment.

Should splenic autotransplantation be considered after total splenectomy due to trauma? / Autoimplante esplênico deve ser considerado para pacientes submetidos à esplenectomia total por trauma?

ABSTRACT Trauma is a public health problem and the most common cause of death in people under the age of 45. In blunt abdominal trauma, the spleen is the most commonly injured organ. Splenectomy remains the most common treatment, especially in high-grade lesions, despite increased nonoperative treatment. Removal of the spleen leads to increased susceptibility to infections due to its role in the immune function. Postsplenectomy sepsis is an important complication and presents a high mortality rate. Patients undergoing splenectomy should be immunized for encapsulated germs, as these are the agents most commonly associated with such infections. Splenic autotransplantation is a simple procedure, which can be an alternative to reduce infection rates consequent to total splenectomy, and reduce costs related to hospitalizations. This review aims to provide evidence-based information on splenic autotransplantation and its impact on the prognosis of patients undergoing total splenectomy. We searched the Cochrane Library, Medline/PubMed, SciELO and Embase, from January 2017 to January 2018 and selected articles in English and Portuguese, dated from 1919 to 2017. We found that the adjusted risk of death in splenectomized patients is greater than that of the general population, and when total splenectomy is performed, splenic autotransplantation is the only method capable of preserving splenic function, avoiding infections, especially postsplenectomy sepsis. Health professionals should be familiar with the consequences of the method chosen to manage the patient suffering from splenic trauma.

RESUMO O trauma é um problema de saúde pública e a causa mais comum de óbito em pessoas com menos de 45 anos de idade. Nos traumas abdominais contusos, o baço é o órgão mais comumente lesado. A esplenectomia continua sendo o tratamento mais comum, especialmente em lesões de alto grau, apesar do aumento do tratamento não operatório. A remoção do baço gera aumento da suscetibilidade a infecções, devido ao seu papel na função imune. Sepse pós-esplenectomia é uma importante complicação e apresenta alta taxa de mortalidade. Pacientes submetidos à esplenectomia devem receber imunização para germes encapsulados, por serem os agentes mais comumente relacionados a essas infecções. Autoimplante esplênico é um procedimento simples, que pode ser alternativa para reduzir índices de infecção consequentes à esplenectomia total, e que pode reduzir custos relacionados à internações. Este trabalho de revisão objetiva prover informações baseadas em evidências sobre o autoimplante esplênico e seu impacto no prognóstico de pacientes submetidos à esplenectomia total. Foram realizadas buscas na Cochrane Library, Medline/PubMed, SciELO e Embase, de janeiro de 2017 a janeiro de 2018 e selecionados artigos em inglês e português, datados de 1919 a 2017. Verificou-se que o risco ajustado de morte em pacientes esplenectomizados é maior do que o da população geral, e quando a esplenectomia total é realizada, o autoimplante esplênico é o único método capaz de preservar a função esplênica, evitando infecções, principalmente sepse pós-esplenectomia. Profissionais de saúde devem estar familiarizados com as consequências do método escolhido para manejar o paciente vítima de trauma esplênico.

Una notable convergencia semántica: infección y miasma / A remarkable semantic convergence: infection and miasma

Resumen Se analiza el desarrollo histórico de los términos "infección" y "miasma". Se entendía por miasma un tipo de aire corrupto o pestilente que emanaba de cuerpos en putrefacción y que propalaba las enfermedades infecciones. Dicho concepto fue el dominante para comprender la causa de las enfermedades infecciosas desde la antigüedad hasta los albores de la teoría microbiana. El concepto de infección tuvo inicialmente un significado similar al de miasma, pero actualmente se define como la invasión de un hospedero por un agente infeccioso. En este trabajo se discutirá que ambos términos derivan del mismo concepto original.

The historical development of the terms "infection" and "miasma" is analyzed. Miasma was understood as a kind of corrupt or pestilent air that emanated from putrefactive bodies and spread infectious diseases. This concept was the dominant one to understand the cause of infectious diseases from antiquity to the dawn of the microbial theory. The concept of infection initially had a similar meaning to miasma, but is currently defined as the invasion of a host by an infectious agent. It will be discussed in this paper that both terms derive from the same original concept.

Blood transfusion and increased perioperative risk in coronary artery bypass grafts

Abstract Objective: To correlate blood transfusions and clinical outcomes during hospitalization in coronary artery bypass grafting surgery (CABG). Methods: Transfusion, clinical and hematological data were collected for 1,378 patients undergoing isolated or combined CABG between January 2011 and December 2012. The effect of blood transfusions was evaluated through multivariate analysis to predict three co-primary outcomes: composite ischemic events, composite infectious complications and hospital mortality. Because higher risk patients receive more transfusions, the hospital mortality outcome was also tested on a stratum of low-risk patients to isolate the effect of preoperative risk on the results. Results: The transfusion rate was 63.9%. The use of blood products was associated with a higher incidence of the three coprimary outcomes: composite infectious complications (OR 2.67, 95% CI 1.70 to 4.19; P<0.001), composite ischemic events (OR 2.42, 95% CI 1.70 to 3.46; P<0.001) and hospital mortality (OR 3.07, 95% CI 1.53 to 6.13; P<0.001). When only patients with logistic EuroSCORE ≤ 2% were evaluated, i.e., low-risk individuals, the mortality rate and the incidence of ischemic events and infectious complications composites remained higher among the transfused patients [6% vs. 0.4% (P<0.001), 11.7% vs. 24,3% (P<0.001) and 6.5% vs. 12.7% (P=0.002), respectively]. Conclusion: The use of blood components in patients undergoing CABG was associated with ischemic events, infectious complications and hospital mortality, even in low-risk patients.

Impacto de las complicaciones infecciosas postoperatorias en la sobrevida a largo plazo de pacientes gastrectomizados por carcinoma gástrico avanzado con intención curativa / Impact of infectious postoperative complications in the long term survival of patients gastrectomized for gastric carcinoma with curative intent

Objetivo: Comprobar el impacto de las complicaciones infecciosas postoperatorias en la sobrevida a largo plazo de pacientes gastrectomizados por carcinoma gástrico con intención curativa. Materiales y métodos: El presente estudio de cohortes evaluó una serie de 79 pacientes con diagnóstico de carcinoma gástrico avanzado resecable con intención curativa. Se agruparon a su vez: Grupo A (N=28): Pacientes con complicaciones infecciosas postoperatorias y Grupo B (N=51): Pacientes que no presentaron complicaciones infecciosas postoperatorias. El estudio abarcó los años 2008-2013. Resultados: En el grupo A, las tasas de sobrevida a 1, 3 y 5 años fueron de 74%, 74% y 47,6% respectivamente. En el grupo B, las tasas de sobrevida a 1, 3 y 5 años fueron de 80,3%, 56% y 49,8% respectivamente (p=0,365). Las principales complicaciones infecciosas postoperatorias no relacionadas con la técnica quirúrgica fue la neumonía (20,3%), seguida de infección del tracto urinario (3,8%). Las principales complicaciones infecciosas postoperatorias relacionadas con la técnica quirúrgica fue la sepsis (n=5), dos de estos pacientes presentaron de dehiscencia de anastomosis esofagoyeyunal, dos presentaron fístula gastroyeyunal, uno fístula enterocutánea y por último un paciente presentó absceso y necrosis de tejido peripancreático. Conclusiones: No hubo un impacto en la sobrevida a 5 años en pacientes con complicaciones infecciosas postoperatorias post gastrectomía con intención curativa. Sin embargo, más estudios adicionales deberían efectuarse.

Objective: To determine the impact of postoperative infectious complications in the long term survival of patients gastrectomized for gastric carcinoma with curative intent. Materials and methods: The present cohort study evaluated a series of 79 patients diagnosed with resectable advanced gastric carcinoma with curative intent. They were grouped in: Group A (N=28): patients with postoperative infectious complications and Group B (N=51): patients who did not develop postoperative infectious complications. The study covered the years 2008-2013. Results: In group A, the survival rates at 1, 3 and 5 years was 74%, 74% and 47.6% respectively. In group B, the survival rates at 1, 3 and 5 years was 80.3%, 56% and 49.8% respectively (p=0.365). The main postoperative infectious complications not related to the surgical technique were pneumonia (20.3%), followed by urinary tract infection (3.8%). The main postoperative infectious complications related to surgical technique was sepsis (n=5), two of which were related to dehiscence esophagojejunal anastomosis, two bye gastroyeyunal fistula, another bye enterocutaneous fistula and one patient who presented abscess and necrosis peripancreatic’s tissue. Conclusions: There was no impact on survival at 5 years in patients with postoperative infectious complications after gastrectomy with curative intent. However, further studies should be carried over.

Factores pronósticos de complicaciones postquirúrgicas en pacientes con infecciones óseas y seudoartrosis / Prognostic factors for post surgical complications in bone infection and pseudarthrosis

Resumen: La infección ósea y la seudoartrosis son las principales complicaciones ortopédicas en cuyo tratamiento intervienen múltiples factores en la tasa de falla al tratar de corregirlas. Conocer estos factores fue el problema que originó la investigación a través de un estudio longitudinal y prospectivo de una cohorte histórica de 83 pacientes de 43.3 ± 16.1 años de edad tratados por seudoartrosis asépticas y sépticas, osteomielitis, osteítis, consolidación viciosa o prótesis infectadas, el desenlace se relacionó con los factores pronósticos sistémicos y locales tomados del modelo de Cierny-Mader como factores que afectan la vigilancia inmunológica, el metabolismo y la vascularización local. Para el análisis bivariado se aplicó χ2 o el test exacto de Fisher; para el análisis multivariado se aplicó el modelo de regresión logística binaria no condicional con método de Wald hacia atrás para seleccionar los factores pronósticos significativos. El error alfa se fijó ≤ 0.05. Las complicaciones se presentaron en 51.8% de los casos. Los factores locales (linfedema, arteritis, insuficiencia venosa y pérdida de piel) con una OR de 5.0 (IC 95% 1.0-24.9, p = 0.03), las seudoartrosis sépticas con OR de 5.0 (IC 95% 1.9-13.0, p = 0.001) y fracturas segmentarias con OR de 3.2 (IC 95% 0.8-13.0, p = 0.07) fueron los factores pronósticos identificados en el análisis bivariado; sin embargo, la regresión logística sólo seleccionó como factor significativo a las seudoartrosis sépticas. Es necesario detectar y en su caso controlar o eliminar dichos factores que pueden incidir directamente en malos resultados postquirúrgicos.

Abstract: Bone infection and nonunion are the main orthopedic and traumatic complications whose treatment remains a challenge because multiple factors are involved in the rate of failures when you try to correct them. Knowing these factors were the problem that caused the research through a prospective longitudinal study of 83 patients of 43.3 ± 16.1 years old. They were treated for aseptic and septic nonunion, osteomyelitis, osteitis, malunion or infected joint replacement. The cases were classified with or without postoperative complications and outcome related to systemic and local factors taken prognostic model Cierny-Mader as factors affecting immune surveillance, metabolism and local vascularization. For bivariate analysis of data χ2 it was applied or where appropriate Fisher's exact test; for multivariate analysis model not conditional binary logistic regression method was applied Wald backward to select the significant prognostic factors. The alpha error was set ≤ 0.05. General complications occurred in 51.8% of cases. Local factors (lymphedema, arteritis, venous insufficiency, loss of skin) with an OR of 5.0 (95% CI 1.0-24.9, p = 0.03), septic nonunion with OR of 5.0 (95% CI 1.9-13.0, p = 0.001) and segmental fractures with an OR of 3.2 (95% CI 0.8-13.0, p = 0.07) were the prognostic factors identified in the bivariate analysis; however, the logistic regression only selected as the septic pseudoarthrosis as a significant factor. It is necessary to detect and if necessary control or eliminate those factors that can directly affect poor postoperative results.

Hemorragia subaracnóidea espontânea não aneurismática: perimesencefálica versus não perimesencefálica / Non-aneurysmal spontaneous subarachnoid hemorrhage: perimesencephalic versus non-perimesencephalic

RESUMO Objetivo: Comparar a evolução clínica da hemorragia subaracnóidea perimesencefálica com a da hemorragia subaracnóidea não perimesencefálica. Métodos: Estudo retrospectivo, que incluiu pacientes portadores de hemorragia subaracnóidea sem causa conhecida em um hospital terciário localizado na região norte de Portugal. Os dados epidemiológicos, clínicos e de imagem foram analisados estatisticamente, levando em conta a divisão dos pacientes em duas categorias: hemorragia subaracnóidea perimesencefálica e hemorragia subaracnóidea não perimesencefálica. Resultados: Cumpriram os critérios de inclusão 62 pacientes, 46,8% deles com hemorragia subaracnóidea perimesencefálica e 53,2% com hemorragia subaracnóidea não perimesencefálica. As caraterísticas demográficas, assim como os antecedentes clínicos, foram similares entre os grupos. As complicações foram observadas mais comumente no grupo com hemorragia subaracnóidea não perimesencefálica, sendo que 84,8% desses pacientes tiveram, no mínimo, uma complicação, comparados a 48,3% dos pacientes com hemorragia subaracnóidea perimesencefálica. Vasoespasmo, infecções e hidrocefalia foram as complicações mais comuns - todas observadas mais frequentemente nos pacientes com hemorragia subaracnóidea não perimesencefálica. Dois pacientes vieram a falecer, ambos com hemorragia subaracnóidea não perimesencefálica. A mediana do tempo de permanência no hospital foi maior nos pacientes com hemorragia subaracnóidea não perimesencefálica (21 dias, em comparação aos 14 dias observados nos pacientes com hemorragia subaracnóidea perimesencefálica). Não se observaram recidivas de sangramento durante o acompanhamento (tempo médio de 15 ± 10,3 meses). Conclusão: As hemorragias subaracnóideas perimesencefálica e não perimesencefálica tiveram formas diferentes de evolução clínica, principalmente no que se referiu à taxa de complicações e ao tempo mediano de permanência no hospital. Assim, a abordagem dessas duas formas de hemorragia subaracnóidea deve ser distinta, tanto em busca de melhorar o tratamento dos pacientes quanto para obter um melhor aproveitamento dos recursos de saúde.

ABSTRACT Objective: To compare the clinical evolution of perimesencephalic subarachnoid hemorrhage and non-perimesencephalic subarachnoid hemorrhage. Methods: The study was conducted retrospectively in a tertiary hospital center in the north region of Portugal. Included patients had no identifiable cause for subarachnoid hemorrhage. Several epidemiologic, clinical and imaging aspects were statistically analyzed, taking into account the differences in perimesencephalic subarachnoid hemorrhage and non-perimesencephalic subarachnoid hemorrhage. Results: Sixty-two patients met the inclusion criteria (46.8% - perimesencephalic subarachnoid hemorrhage; 53.2% - non-perimesencephalic subarachnoid hemorrhage). Demographic and clinical background characteristics were similar in both groups. Complications were more frequent in patients with non-perimesencephalic subarachnoid hemorrhage - 84.8% of the patients had at least one complication versus 48.3% in perimesencephalic subarachnoid hemorrhage. Vasospasm, infection and hydrocephaly were the most common complications (each was detected more frequently in the non-perimesencephalic subarachnoid hemorrhage group than in perimesencephalic subarachnoid hemorrhage group). Two patients died, both had a non-perimesencephalic subarachnoid hemorrhage. The median inpatient time was longer in the non-perimesencephalic subarachnoid hemorrhage group (21 versus 14 days). No incidents of rebleeding were reported during the follow-up period (mean time of 15 ± 10.3 months). Conclusion: Perimesencephalic subarachnoid hemorrhage and non-perimesencephalic subarachnoid hemorrhage are two different entities that have different clinical outcomes, namely in terms of complication rate and median inpatient time. The management of these patients should respect this difference to improve treatment and optimize health care resources.
