[Multi-organ failure as first clinical sign of macrophage activation syndrome in childhood Still's disease]. / Fracaso multiorgánico como forma de presentación del síndrome de activación macrofágica en la enfermedad de Still infantil.

Macrophage activation syndrome is a form of secondary haemophagocytic lymphohistiocytosis seen in the context of rheumatic diseases. It is seen most frequently in association with systemic onset juvenile arthritis or childhood Still's disease. Hemophagocytosis is part of a sepsis-like clinical syndrome caused by hypercytokinemia due to a highly stimulated but ineffective immune response. Coagulopathy and hemorrhages, decreased white cell count, elevated levels of aspartate aminotransferase, fever, rash, hepatosplenomegaly and central nervous system dysfunction are some of diagnostic criteria of macrophage activation syndrome, but it is very difficult to diagnose due to the lack of specific clinical signs. We report a 8-year-old child who was admitted to the ICU with lethargy, fever, acute respiratory failure, coagulopathy, metabolic acidosis and multiorgan failure. Septic shock was suspected, but he was diagnosed with macrophage activation syndrome and treated with corticosteroids and intravenous immunoglobulin and later discharged from the ICU.

[Training in the care of the critical and multiple-injured patient: role of clinical simulation]. / Formación en la asistencia al paciente crítico y politraumatizado: papel de la simulación clínica.

Clinical simulation is suggested as a new educational instrument to learn and train in different medical skills. It is conceived as a new method that integrates scientific knowledge and human factors. Experience with these systems has been limited up to now, but it is now being widely accepted since it seems to accelerate acquisition of skills and knowledge in a safe setting, that is, without risk for the patient. However, its effect on clinical performance has not been validated yet. They are two types of simulators for intensive cares: screen based and human patient simulator (HPS). These systems make it possible to simulate different situations that require the application of action protocols or the management of new drugs in the clinical practice, promoting the rational use of resources in urgent care of the critical and multiple-injured patients. The limiting factors that prevent the expansion of the simulation for clinical training are its high cost, human resources needed, and the difficulties to assess the effectiveness of the training in real situations.

[Acute respiratory infections in pediatric intensive care units. A multicenter prospective study]. / Infecciones respiratorias agudas en unidades de cuidados intensivos pediátricos. Estudio prospectivo multicéntrico.

OBJECTIVE: The purpose of this study was to know the etiology, clinical background, treatment an evolution of severe infectious diseases in children admitted to Pediatric Intensive Care Units (PICUs). PATIENTS AND METHODS: A multicenter prospective study was carried out. Children with respiratory infections admitted to 10 PICUs throughout Spain between May 1994 and April 1995 were included in a long term survey. The nosocomial infections were not included. Student's t and Wilcoxon tests were used for quantitative variables and Chi square with Yates correction and Fisher's test for the qualitative variables. RESULTS: One hundred twenty-two patients with acute respiratory infections were studied. The mean value on Downes score at admittance was 5.2 +/- 2.3. Diagnosis were allocated as follows: 47 bronchopneumonia (38.5%), 40 bronchiolitis (33%), 15 epiglotitis (12%), 14 laryngitis (11.5%) and "others" 6 (5%). Etiologic agents were identified in 69 cases (56.5%), with respiratory syncytial virus being the most frequently isolated agent (35 cases, 51%), followed by Hemophilus influenzae in 13 cases (19%). The mean PICU stay was 5.8 +/- 7.9 days (1-67 days). Of these cases, 112 (92%) recovered completely and 9 (7%) died (8 with bronchopneumonia and 1 with epiglotitis). A significant association could be seen between the increase in mortality and the variables Downes' score and diagnosis of bronchopneumonia. CONCLUSIONS: The most frequent respiratory infections in the PICU were pneumonia and bronchopneumonia. Viral etiology, with a frequency of 54%, was the main cause of respiratory infection. Bacterial etiology represented 46% of the total cases, with Hemophilus influenzae as the most frequent etiologic agent.

[Recurrent ARDS in varicella pneumonia complicated by disseminated candidiasis in a pregnant woman]. / SDRA recurrente tras neumonía varicelosa complicado con candidiasis diseminada en mujer gestante.

Adult respiratory distress syndrome (ARDS) seems to be the common way from different etiologies. We describe the clinical evolution of an ARDS in a pregnant woman, initially due to Varicella Pneumonia which was complicated with Disseminated Candidiasis and recurrent ARDS. We review the nosocomial infection with Candida in ICU patients: the growing incidence, the diagnostic problems and the new standards for treatment.

[Definitions of sepsis in severe juvenile meningococcal infection. A review of 80 cases]. / Definiciones de sepsis en la infección meningocócica infantil grave. Una revisión de 80 casos.

OBJECTIVE: To describe the definitions for sepsis proposed by ACCP/SCCM Consensus Conference and to evaluate its capacity to classify children with severe meningococcal infection in homogeneous risk groups. METHODS: Eighty children with acute meningococcal infection and severe sepsis or septic shock, admitted to the pediatric ICU during a ten years period were reviewed. Mean age: 38 months (1,3 mo-14 yrs). RESULTS: N. meningitidis was isolated in 84%. Sixty-four percent of the patients were bacteremic and 39% showed a positive culture in CSF. Overall mortality was 19%. Fifty-two patients (65%) were in severe sepsis on admission, fifteen of them (29%) developed shock, mortality for this group was 4%. Twenty-eight patients (35%) were in septic shock on admission, mortality was 44%. Overall mortality of the shock group was 35%, mortality of shock on admission was higher than mortality of shock postadmission (44% vs 13%, p = 0.0001). Major complications were: DIC (28%), ARDS (26%), purpura fulminans (21%). There were not major complications or deaths in patients who did not develop shock. Bacteremia was not significant associated with shock or death. Meningitis was more frequent in severe sepsis group but 62% of deaths got it. Univariant analysis showed significant differences between both groups relative to tissular perfusion variables, coagulation and meningeal involvement. Multivariate analysis allowed us to establish a predictive model of survival feasible on admission to the ICU. For its determination three parameters are used: blood pressure, platelets and base excess. CONCLUSION: Definitions proposed for severe sepsis and septic shock are a valuable tool to classify children with acute meningococcal infection in homogeneous risk groups.
