RESUMEN
La neumonía adquirida en la comunidad constituye una de las afecciones respiratorias que provoca más demanda de asistencia médica, y es responsable del mayor número de fallecidos por enfermedades infecciosas en Cuba. El objetivo del estudio ha sido determinar el comportamiento de características seleccionadas en pacientes hospitalizados por neumonía y precisar la existencia de asociaciones entre algunas de estas características.Se realizó un estudio observacional, con diseño descriptivo, que incluyó 1,809 pacientes hospitalizados por neumonía entre enero de 2012 y febrero de 2020. Fueron analizadas características relacionadas con las condiciones de base, clínico-radiológicas, y relativas al manejo y la evolución, mediante análisis bivariante y multivariante (regresión logística). La serie estuvo constituida fundamentalmente por pacientes ancianos (79%), mientras que el 20% presentaba la condición de encamamiento. Esta condición se asoció significativamente con el estado de demencia avanzada (OR 7,6[5,5;10,4]), y fue determinante en la presentación "solapada" del proceso (OR 1,5[1,09;2]). La presentación "solapada" de la neumonía estuvo significativamente asociada al ingreso tardío (OR 1,6[1,2;2,2]). Como conclusiones se ratifica el lugar que ocupan varios elementos en las características de la morbilidad por neumonía: edad avanzada, presencia de comorbilidades, y presentación no clásica del proceso. Fueron constatadas interrelaciones de importancia práctica entre la presencia de comorbilidades particulares, las formas clínicas de presentación, el momento del ingreso, y la utilización de antimicrobianos durante la atención prehospitalaria del paciente. Se destaca el papel del encamamiento en la extensión radiológica del proceso neumónico y en la presencia de derrame pleural de mediana o gran cuantía al momento del ingreso.
Community-acquired pneumonia is one of the respiratory conditions that causes the greatest demand for medical care, and is responsible for the largest number of deaths from infectious diseases in Cuba. The objective of the study was to determine the behavior of selected characteristics in patients hospitalized for pneumonia and to specify the existence of associations between some of these characteristics. An observational study, with a descriptive design, was carried out, which included 1,809 patients hospitalized for pneumonia between January 2012 and February 2020. Characteristics related to the basic, clinical-radiological conditions, and relative to management and evolution were analyzed, through analysis bivariate and multivariate (logistic regression). The series consisted mainly of elderly patients (79%), while 20% were bedridden. This condition was significantly associated with the state of advanced dementia (OR 7.6[5.5;10.4]) and was decisive in the "overlapping" presentation of the process (OR 1.5[1.09;2]). The "overlapping" presentation of pneumonia was significantly associated with late admission (OR 1.6[1.2;2.2]). As conclusions, the place occupied by several elements in the characteristics of pneumonia morbidity is ratified: advanced age, presence of comorbidities, and non-classical presentation of the process. Interrelationships of practical importance were found between the presence of comorbidities, the clinical forms of presentation, the time of admission, and the use of antimicrobials during the patient's prehospital care. The role of bed rest in the radiological extension of the pneumonic process and in the presence of medium or large pleural effusion at the time of admission is highlighted.

ABSTRACT Objective: To determine the incidence of the reversed halo sign (RHS) in patients with pulmonary infarction (PI) due to acute pulmonary embolism (PE), detected by computed tomography angiography (CTA) of the pulmonary arteries, and to describe the main morphological features of the RHS. Methods: We evaluated 993 CTA scans, stratified by the risk of PE, performed between January of 2010 and December of 2014. Although PE was detected in 164 scans (16.5%), three of those scans were excluded because of respiratory motion artifacts. Of the remaining 161 scans, 75 (46.6%) showed lesions consistent with PI, totaling 86 lesions. Among those lesions, the RHS was seen in 33 (38.4%, in 29 patients). Results: Among the 29 patients with scans showing lesions characteristic of PI with the RHS, 25 (86.2%) had a single lesion and 4 (13.8%) had two, totaling 33 lesions. In all cases, the RHS was in a subpleural location. To standardize the analysis, all images were interpreted in the axial plane. Among those 33 lesions, the RHS was in the right lower lobe in 17 (51.5%), in the left lower lobe in 10 (30.3%), in the lingula in 5 (15.2%), and in the right upper lobe in 1 (3.0%). Among those same 33 lesions, areas of low attenuation were seen in 29 (87.9%). The RHS was oval in 24 (72.7%) of the cases and round in 9 (27.3%). Pleural effusion was seen in 21 (72.4%) of the 29 patients with PI and the RHS. Conclusions: A diagnosis of PE should be considered when there are findings such as those described here, even in patients with nonspecific clinical symptoms.
RESUMO Objetivo: Verificar a incidência do sinal do halo invertido (SHI) associado a infartos pulmonares (IP) relacionados ao tromboembolismo pulmonar (TEP) agudo, identificado por angiotomografia (angio-TC) de artérias pulmonares, e demonstrar as principais características morfológicas do SHI. Métodos: Foram avaliadas 993 angio-TCs, após estratificação de risco clínico para TEP entre janeiro de 2010 e dezembro de 2014. TEP foi encontrado em 164 pacientes (16,5%), sendo que três exames foram descartados devido a artefatos de movimentação respiratória. Dos 161 exames restantes, em 75 (46,6%) foram identificadas imagens compatíveis com IP, totalizando 86 lesões; o SHI foi observado em 33 (38,4% dos pacientes) dessas lesões. Resultados: Dos 29 pacientes com lesões características de IP com o SHI, 25 pacientes (86,2%) apresentavam lesão única e 4 (13,8%), lesão dupla. Todas as imagens compatíveis com SHI eram de localização subpleural. Para padronizar a análise, todas as imagens foram interpretadas no plano axial. Em relação à distribuição lobar das 33 lesões, o SHI estava localizado no lobo inferior direito, em 17 (51,5%); no lobo inferior esquerdo, em 10 (30,3%); na língula, em 5 (15,2%) e no lobo superior direito, em 1 (3,0%). Áreas de baixa atenuação no interior dos IPs com o SHI foram observadas em 29 das 33 lesões (87,9%). O SHI apresentava formato ovalado em 24 (72,7%) dos casos e formato arredondado, em 9 (27,3%). Derrame pleural foi encontrado associado aos IP com o SHI em 21 pacientes (72,4%). Conclusões: O achado de imagens com essas características, mesmo em pacientes com sintomatologia inespecífica, deve alertar para a possibilidade do diagnóstico de TEP.

AbstractObjective:The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting.Methods:A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden) heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11.Results:The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump) as compared to Group 2 (off-pump). But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893), P>0.05 for bilateral pleural effusion (P=0.780)]. Left pleural effusion was encountered to be lower in Group 2 (off-pump). The difference was found to be statistically significant (P<0.05, P=0.006).Conclusion:Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.
ResumoIntrodução:O presente estudo investigou efeito da utilização de bomba em derrame pleural pós-operatório nos casos de pacientes que se submeteram à cirurgia de revascularização miocárdica.Métodos:Um total de 256 pacientes que foram submetidos à cirurgia de revascularização isolada no ambulatório de Cirurgia Cardiovascular foram incluídos no estudo. Máquina coração-pulmão Jostra-Cobe (Modelo 043213 105, VLC 865, Suécia) foi utilizada em cirurgia de revascularização miocárdica com circulação extracorpórea. Cirurgia de revascularização miocárdica sem circulação extracorpórea foi realizada utilizando Octopus e Starfish. Anastomose proximal na aorta, em ambas as técnicas, foi realizada por grampos laterais. Os pacientes receberam alta do hospital entre os dias 6 e 11 de pós-operatório.Resultados:A incidência de derrame pleural à direita pós-operatória e derrame pleural bilateral encontrada foi mais elevada em contagem do Grupo 1 (com circulação extracorpórea) em relação ao Grupo 2 (sem circulação extracorpórea). Mas a diferença não foi estatisticamente significativa [P>0,05 para derrame pleural à direita (P=0,893), P>0,05 para derrame pleural bilateral (P=0,780)]. O derrame pleural esquerdo encontrado foi menor no Grupo 2 (CEC). A diferença foi estatisticamente significativa (P<0,05, P=0,006).Conclusão:Sob a luz destes resultados, pode-se dizer que derrame pleural esquerdo é menos prevalente nos pacientes que foram submetidos à revascularização do miocárdio sem circulação extracorpórea em comparação com os pacientes que foram submetidos à revascularização do miocárdio com circulação extracorpórea.

Background. Pleural effusions of diverse aetiologies are encountered in patients with chronic kidney disease (CKD). The objectives of the present study were to examine the frequency of occurrence, causes, clinical features and management strategies of pleural effusion in patients with CKD including renal transplant recipients. Methods. A prospective cross-sectional observational analysis of pleural effusion in adult patients with CKD (stages 3 to 5) attending the Departments of Nephrology and Respiratory Medicine of a tertiary care institution in Eastern India was performed over a period of one year (February 2010 to January 2011). Results. Pleural effusion was found in 29 out of 430 patients with CKD (6.7%) and in two out of 34 post-renal transplant recipients (5.9%) evaluated during the study period. The mean age was 37.35±1.8 (mean±SEM [standard error of mean]) with a male to female ratio of 2:1. Exudates and transudates were found in equal frequencies. Heart failure was the single most common cause (41.9%, 13 of 31). Tuberculosis (TB) (n=8, 25.8%) and uraemic effusions (n=6, 19.4%) were responsible for the majority of exudates. Unilateral effusion with a normal heart size had a positive predictive value of 83.3% for nonheart failure aetiology. Conclusions. Symptomatic pleural effusion was present in a small proportion of 6.7%; (n=29) patients with CKD including post-renal transplant recipients. Heart failure, TB and uraemic effusions accounted for most of the cases. Differentiating TB from uraemic effusion requires a combined clinico-pathological approach and this differentiation is absolutely necessary for proper management.

OBJETIVO: Determinar a prevalência e as características da pneumonia adquirida na comunidade (PAC) e derrames pleurais parapneumônicos (DPP) relacionados a Mycoplasma pneumoniae em um grupo de crianças e adolescentes. MÉTODOS: Estudo observacional retrospectivo com 121 pacientes hospitalizados com PAC e DPP em um hospital de referência terciária, entre 2000 e 2008, divididos em seis grupos (G1 a G6) segundo o agente etiológico: M. pneumoniae com ou sem coinfecção, em 44 pacientes; outros agentes que não M. pneumoniae, em 77; M. pneumoniae sem coinfecção, em 34; Streptococcus pneumoniae, em 36; Staphylococcus aureus, em 31; e coinfecção M. pneumoniae/S. pneumoniae, em 9, respectivamente. RESULTADOS: Na comparação entre os grupos, G1 apresentou frequências maiores em gênero feminino, tosse seca, uso prévio de beta-lactâmicos e na duração dos sintomas até a admissão, assim como menor uso de assistência ventilatória e de drenagem torácica que G2, enquanto G3 teve maiores frequências em uso prévio de beta-lactâmicos e tosse seca, maior duração dos sintomas antes da admissão e menor frequência de uso de drenos torácicos que G4 e G5, ao passo que G3 teve média de idade maior e menor frequência de náuseas/vômitos que G4, assim como menor uso de assistência ventilatória que G5. A coinfecção M. pneumoniae/S. pneumoniae aumentou a duração dos sintomas até a admissão. CONCLUSÕES: Nesta amostra, a prevalência de PAC e DPP por M. pneumoniae foi de 12,75%. Embora a doença apresentasse quadros mais leves que aquela por outros organismos, a evolução foi mais prolongada. Nossos dados sugerem a necessidade de uma maior diligência na investigação de M. pneumoniae em crianças e adolescentes com PAC e DPP em nosso meio.
OBJECTIVE: To determine the prevalence and the characteristics of Mycoplasma pneumoniae-related community-acquired pneumonia (CAP) and parapneumonic pleural effusion (PPE) in children and adolescents. METHODS: This was a retrospective observational study involving 121 patients with CAP/PPE hospitalized in a tertiary referral hospital between 2000 and 2008, divided into six groups according to the etiologic agent (G1 to G6, respectively): M. pneumoniae with or without co-infection, in 44 patients (group 1); etiologic agents other than M. pneumoniae, in 77 (group 2); M. pneumoniae without co-infection, in 34 (group 3); Streptococcus pneumoniae, in 36 (group 4); Staphylococcus aureus, in 31 (group 5); and M. pneumoniae/S. pneumoniae co-infection, in 9 (group 6). RESULTS: In comparison with group 2, group 1 showed higher frequencies of females, dry cough, and previous use of beta-lactam antibiotics; longer duration of symptoms prior to admission; and lower frequencies of use of mechanical ventilation and chest tube drainage. In comparison with groups 4 and 5, group 3 showed higher frequencies of previous use of beta-lactam antibiotics and dry cough; longer duration of symptoms prior to admission; a lower frequency of use of chest tube drainage; a higher mean age and a lower frequency of nausea/vomiting (versus group 4 only); and a lower frequency of use of mechanical ventilation (versus group 5 only). M. pneumoniae/S. pneumoniae co-infection increased the duration of symptoms prior to admission. CONCLUSIONS: In this sample, the prevalence of M. pneumoniae-related CAP/PPE was 12.75%. Although the disease was milder than that caused by other microorganisms, its course was longer. Our data suggest that M. pneumoniae-related CAP and PPE in children and adolescents should be more thoroughly investigated in Brazil.

Introducción: El empiema pleural (EP) es una complicación grave de la neumonía adquirida en la comunidad (NAC). Objetivos: Describir las características de los pacientes hospitalizados por EP en el Servicio de Pediatría del Hospital de la Universidad Católica durante el período 2000-2005. Se identificaron 86 hospitalizaciones por NAC con efusión pleural, practicándose en 59 (70 por ciento), al menos una toracocentesis. Se consideró EP a la presencia de pus, tinción de Gram con bacterias, cultivo positivo o pH < 7,10 en el líquido pleural, siendo las efusiones para-neumónicas los controles. Resultados: Se analizaron 24 EP y 25 controles [promedio 2,9 años (rango: 8 meses - 14,3 años)], 78 por ciento de edad inferior a 5 años con diferencia entre los grupos EP y controles [1,6 vs 3,3 años, respectivamente (p = 0,01)]. El promedio global (días) de síntomas previo al ingreso en los EP fue 7 (rango: 2-21), siendo los más frecuentes fiebre (100 por ciento) y tos (96 por ciento). Se identificó algún microorganismo en 15/24 EP, Streptococcus pneumoniae fue el más frecuente (n: 9). En 48 niños, el manejo inicial fue conservador, requiriéndose cuatro rescates quirúrgicos luego del cuarto día. El promedio (días) de hospitalización fue significativamente superior en el grupo EP vs controles [15 (rango: 5-38) vs 9 (rango: 3-16) (p < 0,01)]. Requirieron drenaje pleural 83 por ciento del grupo EP y 36 por ciento de los controles (p = 0,002). No hubo diferencia en el número de días de empleo de oxígeno [6 vs 4,5 (p = 0,36)] o drenaje pleural [3 vs 2,5 (p = 0,29)]. No se registraron fallecidos. Conclusión: El EP en niños fue una condición respiratoria aguda que se asoció a estadías hospitalarias prolongadas, especialmente en los de menor edad, no requiriéndose, en la mayoría, una intervención quirúrgica de rescate.
Introduction: Pleural empyema (PE) is a serious complication of community-acquired pneumonia (CAP). Objectives: To describe the clinical profile of hospitalized patients with PE in the pediatric ward of the Catholic University Hospital between 2000-2005. Patients y methods: Retrospectively, all pediatric admission due to CAP and pleural effusion (86 children) were identified. In 59 (70 percent) children > 1 thoracocentesis were performed. We considered PE as the presence in the pleural effusion of pus, and/or a positive gram strain and/ or positive culture, and/or a pH < 7.10. Children with effusions not meeting any criteria were used as controls. Results: Twenty four PE and 25 controls were identified, with a global mean age of 2.9 years (range: 8 months to 14.3 years); 78 percent were < 5 years, with a significant difference between PE and controls [1.6 vs 3.3 years (p = 0.01)]. The mean duration of symptoms in PE patients before admission was 7 days (range: 2-21), and the most frequent symptoms were fever (100 percent) and cough (96 percent). In 15/24 cases a microorganism was identified being Streptococcus pneumoniae (n = 9) the most common. In 48 patients management was conservative and in 4 surgical procedures were required. The mean duration of hospitalization was significantly higher in the PE group vs controls group: 15 (range: 5-38) vs 9 days (range 3-16) (p < 0.01). A chest tube was inserted in 83 percent of children with EP compared with 36 percent in the control group (p = 0.002). There were no difference in number of days of oxygen use [6 vs 4.5 (p = 0.36)] or number of chest tubes per child [3 vs 2.5 (p = 0.29)]. No deaths were reported. Conclusion: PE in children represented an acute respiratory event associated with more prolonged hospitalization especially at younger ages; the majority of cases did not require surgical intervention.

To evaluate the common causes of pleural effusion in children. Retrospective study. Liaquat University Hospitals Jamshoro, Hyderabad. The data of all paediatric patients of major pleural effusion from January 2005 was collected and analyzed retrospectively to determine the cause of pleural effusion. This study was conducted on 50 patients. The boys were 30 [60%] and 20 [40%] were girls; male to female ration was 3:2. Age range was three years to 14 years. All patients belonged to poor socioeconomic class. The common symptoms were fever and cough. X-Ray chest showed large pleural effusion. Forty [80%] patients were anemic with less than 8gm Hb level. In 39 patients the ESR was less than 40mm in the first hour. The pleural fluid specimen was taken for culture and sensitivity. Sputum was sent for acid fast bacilli. In two patients, the puss was thick; these patients underwent thoracotomy and decortications. Tuberculous pleural effusion was the most commonly encountered. It was found in 35 [66%] cases. The second most common cause was paraneumonic pleural effusion

OBJETIVO: Determinar fatores de risco sócio-ambientais associados ao desenvolvimento de comprometimento pleural em crianças de 3 a 59 meses internadas com pneumonia grave em um hospital do Nordeste brasileiro. MÉTODOS: Estudo observacional, transversal, descritivo, com componente analítico. Foram avaliados 154 pacientes hospitalizados com pneumonia grave, com ou sem comprometimento pleural. O comprometimento pleural foi definido segundo achados radiológicos. As seguintes variáveis sócio-ambientais foram analisadas: faixa etária, sexo, local de residência, condições do domicílio, freqüência à creche, fumo passivo, renda familiar, presença de bens de consumo, escolaridade e trabalho extra-domiciliar da mãe ou responsável pela criança. As informações foram obtidas através de entrevistas com o responsável pelo paciente ou consulta ao prontuário médico durante a hospitalização. RESULTADOS: A freqüência de comprometimento pleural foi de 25,3 por cento. Os seguintes fatores foram associados à ocorrência de comprometimento pleural: residência em zona rural, dois cômodos ou menos no domicílio, renda familiar mensal inferior a 170 dólares e peso de nascimento <2 500 g. CONCLUSÕES: Os achados sugerem a necessidade de priorizar a melhoria das condições socioeconômicas e de moradia da população mais carente, principalmente aquela oriunda do meio rural. O setor saúde deve enfatizar a atenção primária, com enfoque preventivo desde o período pré-natal.
Objective. To determine social and environmental risk factors associated with pleural involvement among children from 3 to 59 months old who were hospitalized with severe pneumonia in northeastern Brazil. Methods. This was an observational and descriptive cross-sectional study with an analytical component. We evaluated 154 patients hospitalized due to severe pneumonia, with or without pleural involvement. Pleural involvement was determined based on radiological findings. The following variables were analyzed: age, sex, place of residence, housing conditions, day care attendance, passive smoking, family income, presence of consumer goods in the home (e.g., television, radio, refrigerator, automobile), and schooling and occupation of the mother or other caregiver. The information was obtained by interviewing the mother or other caregiver or by consulting the inpatient medical chart. Results. The frequency of pleural involvement among the 154 patients evaluated was 25.3%. The following factors were associated with pleural involvement: living in a rural area, being in a household with two or fewer rooms, family income below 170 U.S. dollars per month, and birthweight < 2 500 g. Conclusions. These findings indicate the need to improve the socioeconomic and living conditions of the less-privileged population, especially in rural areas. The health sector should emphasize primary care, focusing on a preventive approach beginning in the prenatal period.

Interstitial pneumonia (IP) frequently occurs in patients with scrub typhus, but its clinical significance is not well known. This study was designed to evaluate interstitial pneumonia as a marker of severity of the disease for patients with scrub typhus. We investigated clinical parameters representing the severity of the disease, and the chest radiographic findings for 101 patients with scrub typhus. We then compared these clinical factors between patients with and without IP. We also studied the relationship between IP and other chest radiographic findings. The chest radiography showed IP (51.4%), pleural effusion (42.6%), cardiomegaly (14.9%), pulmonary alveolar edema (20.8%), hilar lymphadenopathy (13.8%) and focal atelectasis (11.8%), respectively. The patients with IP (n=52) had higher incidences in episode of hypoxia (p=0.030), hypotension (p=0.024), severe thrombocytopenia (p=0.036) and hypoalbuminemia (p=0.013) than the patients without IP (n=49). The patients with IP also had higher incidences of pleural effusion (p<0.001), focal atelectasis (p=0.019), cardiomegaly (p<0.001), pulmonary alveolar edema (p=0.011) and hilar lymphadenopathy (p<0.001) than the patients without IP. Our data suggest that IP frequently occurs for patients with scrub typhus and its presence is closely associated with the disease severity of scrub typhus.

The presence of pleural eosinophilia remains a controversy in etiology and prognosis. We conducted this study to evaluate the etiology of eosinophilic pleural effusion and to define the factors that determine malignancy in eosinophilic pleural effusion. Between 1 August 1994 and 1 July 2000, 50 patients were diagnosed with eosinophilic pleural effusion; 35 men and 15 women averaging 56.4 years of age. Most (96%) had exudative pleural effusion. Malignancy was the most common (46%) established cause followed by tuberculosis (10%), parapneumonic effusion (8%), and empyema thoracis (2%). We encountered only one case of pneumothorax and parasitic pleural effusion (from Strongyloides stercoralis). Unknown causes constituted 22% of cases. The etiology of those who had previously undergone thoracocentesis did not differ from those having their first thoracocentesis. Patients with malignant pleural effusion had significant longer duration of clinical symptoms (> or = 1 month) and weight loss than benign pleural effusion. The median duration of symptoms in benign pleural effusion was 14 days. Fever was more characteristic in patients with benign than in those with malignant pleural effusion. The percentage of eosinophils in pleural fluid and blood did not differ between the two groups. Pleural fluid eosinophils in malignant vs benign pleural effusion were 26.6% (range 10% to 63%), and 30.6% (range 10% to 93%), respectively. We concluded that, pleural eosinophilia did not indicate benign conditions which would spontaneously resolve. Malignant pleural effusion should be considered especially in areas malignancy is prevalent.

Objetivo: Determinar la frecuencia de derrame pleural como complicación de la neumonitis química por ingesta de kerosone, en niños menores de 2 años. Material y métodos: Se realizó un estudio retrospectivo en el Hospital Nacional Cayetano Heredia durante el período 1988-1995. Se revisaron las historias clínicas y las radiografías de los pacientes hospitalizados en el Servicio de Lactancia con diagnóstico de derrame pleural asociado a ingesta de kerosone. Además, se revisó el libro de registros de emergencias pediátricas de 1995 consignando el número de pacientes menores de 24 meses que llegaron por ingesta de kerosone y luego se evaluó cuantos de estos pacientes fueron hospitalizados y además presentaron derrame pleural. Resultados: El 13.5 por ciento de los hospitalizados durante el período 1988-1995 presentaron derrame pleural como complicación a la neumonitis: durante el año 1995, el 10.9 por ciento de los pacientes que llegaron a emergencia por ingesta de kerosone se hospitalizaron.

Introducción: En el estudio de algunos derrames pleurales de tipo exudado, la biopsia pleural informa pleuritis inespecífica (PI). No hay criterios que permitan pronosticar cuál será la evolución de estos pacientes ni hay acuerdo acerca de cuál debe ser la conducta ante el informe de PI. Objetivos: Identificar características clínicas, radiológicas o de laboratorio que permitan predecir la evolución de los pacientes con PI y sugieren la enfermedad subyacente. Pacientes y Métodos: Se revisó la historia y la evolución de los pacientes con derrame de tipo exudado que fueron sometidos a una primera biopsia pleural en la cual una muestra de buena calidad informó PI. Se excluyeron aquellos con ADA > 50 U y citología sospechosa o definitiva de malignidad. Se comparó el número de biopsias y procedimientos a que fue sometido cada paciente después de recibir el informe de PI y los diagnósticos finales. Se buscaron diferencias entre grupos de acuerdo con el diagnóstico definitivo (tuberculosis y cáncer, resolución espontánea, otra causa de PI y muerte sin diagnóstico). Resultados: De 430 biopsias tomadas durante el período de estudio (1991-1993), 60 fueron informadas como PI. Se obtuvieron datos completos en 43 casos. Las características clínicas, radiológicas y bioquímicas fueron similares entre los grupos. Solamente la pérdida de peso se asoció con una mayor probabilidad de tuberculosis o cáncer. El uso de toracoscopia se asoció con mayor probabilidad de alcanzar un diagnóstico definitivo. Conclusión: Si se incluye en la definición de PI un nivel de ADA inferior a 50 U (para excluir TBC) y un resultado de la citología que no sugiera cáncer, ningún factro clínico o paraclínico permite pronosticar la presencia de tuberculosis o cáncer en pacientes con PI. Está indicado continuar el proceso diagnóstico, incluyendo métodos invasivos de estudio de la pleura.

Pulmonary function tests, arterial blood gas tensions and morbidity were compared in 50 patients undergoing coronary artery bypass graft surgery. Thirty patients had bilateral internal mammary grafts (Group 1), 5 patients had only saphenous vein grafts (Group 2) and 15 patients had a single arterial graft in addition to vein grafts (Group 3). Pleural effusion and wound infection were more common in patients with internal mammary artery grafts (p < 0.05). Patients in Group 2 required prolonged ventilation but this could be related to their underlying left ventricular dysfunction. Patients in all the three groups developed a severe restrictive ventilatory defect in the postoperative period and the degree of impairment was maximum in Group 1 patients (p < 0.01). These patients also had evidence of small airway obstruction. Thus an overall decrease in pulmonary function occurs in the postoperative period by 30 to 40% (p < 0.001). The derangement is greater in patients with arterial grafts, as a result of impaired blood supply, increase in pleural drains and additional surgical trauma secondary to mobilization of internal mammary arteries leading to delayed recovery. The awareness of these findings can be of great value in postoperative management of these patients. In addition, these observations should also be kept in mind while planning the choice of grafts in a patient undergoing coronary artery bypass graft surgery.

Se presenta la experiencia en el manejo de 116 derrames pleurales neoplásicos. La metodología empleada para su diagnóstico etiológico partió de una historia clínica completa como elemento orientador y de un modo particular a través del exhaustivo exámen del líquido extraido, indicando practicar la toracocentesis en todos los casos. La punción-biopsia de pleura parietal con la aguja de Abrams, permitió obtener el diagnóstico específico en el 73,3% de los casos. En aquellos pacientes en los que la etiología del derrame no pudo ser demostrada con los métodos mencionados, se indicó exámen pleuroscópico. Se describe ésta técnica empleando toracoscopio rígido, no observándose complicaciones atribuibles al método y alta precisión diagnóstica. En 80 pacientes se instiló hidróxido de sodio al 0,5%, utilizándolo como agente esclerosante para lograr el control del derrame pleural neoplásico, obteniéndose efectividad del 88,75% en lograr sinfisis pleural, una sobrevida promedio de 13,9 meses sin recurrencia del derrame y efectos adversos menores a los observados con otros agentes esclerosantes pleurales.

Un estudio retrospectivo de 47 pacientes con derrame pleural para neumonico y empiema estudiados en el Hospital General de Medellin, Colombia, durante un periodo de cuatro anos mostro que los ninos menores de dos anos son el grupo mas frecuentemente afectados (57%). Los sintomas clinicos de presentacion mas frecuentes fueron: fiebre (100%), taquipnea (93%), disnea y tos (85%). El derrame pleural ocurrio como una enfermedad predominantemente unilateral. Entre los hallazgos radiologicos, los neumatoceles no se observaron estar asociados con un germen en especial. Se presentaron 20 pacientes con empiema (42%) y los germenes mas comunmente aislados fueron el staphilococo aureus y el haemophilus influenzae. Veintisiete pacientes (57%) presentaron derrame paraneumonico y se identifico organismo especifico tan solo en el 18%. Los derrames para neumonicos se trataron sin sonda a torax en el 66% de los pacientes, mientras que fue necesario la colocacion de sonda de torax en el 80% de los pacientes con empiema
