ABSTRACT
Background GuillainBarré syndrome (GBS) is an acute inflammatory polyneuropathy that can lead to respiratory failure. In this study, we evaluate early clinical risk factors for respiratory failure at the time of hospital admission.Methods We studied a retrospective cohort of patients with GBS admitted to a tertiary care center. The potential risk factors studied were sociodemographic characteristics, GBS symptoms, overall and cervical muscle weakness (Medical Research Council [MRC] scores), electromyography findings, and cerebrospinal fluid analysis findings. Unadjusted odds ratios (OR) were calculated and exact logistic regression analysis (adjusted OR) performed to assess the association between baseline risk factors and respiratory failure. Results Overall, 13 of 113 (12%) patients included in the study developed respiratory failure. Unadjusted analyses showed that involvement of any cranial nerve (OR: 14.7; 95% CI, 1.8117.1), facial palsy (OR: 17.3; 95% CI, 2.2138.0), and bulbar weakness (OR: 10.7; 95% CI, 2.350.0) were associated with increased risk of respiratory failure. Lower MRC sum scores (for scores <30, OR: 14.0; 95% CI, 1.54127.2) and neck MRC scores (for scores ≤3, OR: 21.0; 95% CI, 3.5125.2) were associated with higher likelihood of respiratory failure. Adjusted analyses showed that presence of bulbar weakness (OR: 7.6; 95% CI, 1.343.0) and low neck MRC scores (scores ≤3, OR: 9.2; 95% CI, 3.5125.2, vs scores >3) were independently associated with respiratory failure. Conclusions Bulbar and neck muscle weakness at admission are clinical predictors of increased risk of respiratory failure in patients with GBS. These findings could guide the adequate management of high-risk patients. (AU)

Symptomatic pleural collection of cerebrospinal fluid is a rare but accepted complication in hydrocephalic paediatric patients treated with ventriculopleural shunts. Few cases have been described in adults, usually as complication of trauma, tumours or spinal surgery, particularly post-laminectomy. It should be considered in the differential diagnosis of pleural effusion after neurosurgical procedures involving the spine. We describe two patients with large cerebrospinal fluid collections in the pleural cavity caused by postoperative duropleural fistula, who presented with neurological symptoms, cerebrospinal fluid pressure headache and meningitis.

La neumonía por Pneumocystis jirovecii es una infección oportunista frecuente en pacientes positivos al VIH y CD4 < 200 células/mm3. Sin embargo, también se observa en pacientes inmunocomprometidos secundaria al tratamiento con inmunosupresores y altas dosis de esteroides. En estos pacientes, la neumonía grave de la comunidad o la neutropenia febril con infiltrados pulmonares difusos son las presentaciones clínicas más habituales; ambos cuadros cursan generalmente con hipoxemia severa. La falla respiratoria aguda con requerimientos de ventilación mecánica y alto riesgo de muerte intrahospitalaria ocurre con más frecuencia que en los pacientes positivos al VIH. El diagnóstico se realiza con tinción de Grocot, inmunofluorescencia indirecta (lFI) o PCR en lavado broncoalveolar. El tratamiento antibiótico debe incluir trimetoprim-sulfametozaxol y corticoides como adyuvantes. Es frecuente la coinfección con otros patógenos oportunistas, como citomegalovirus o Cándida albicans. Presentamos 4 pacientes VIH negativos, inmunosuprimidos por el tratamiento para enfermedades neoplásicas con neumonía grave por Pneumocystis jirovecii, dos de ellos en el contexto de neutropenia febril y tres con probable co-infección por ctfomegalovirus.
Pneumocystis jirovecii's pneumonia (PCP) is a well known and frequent opportunistic infection in HIV patients with a CD4 cell count under 200 cells/mm3. However, it can be seen in other inmunosupressed patients, secondary to the use of chemotherapy and high dose of steroids. The most common clinical manifestation are severe community-acquired pneumonia and fever with neutropenia plus diffuse lung infiltrates; generally severe hypoxemia is associated with both clinical manifestations. Acute respiratory failure requiring mechanical ventilation and a high risk of death at hospital are more frequent in HIV-negative than in HIV-positive patients. Diagnosis is achieved with Grocot stain, indirect immunofluorescence (IIF) or PCR, in bronchoalveolar lavage samples. Initial treatment should include cotrimoxazole, with adjuvant steroids. Coinfections with other opportunistic pathogens such a Cytomegalovirus or candlda albicans are frequent. The report describes 4 cases of Pneumocystis jirovecii pneumonia, in HIV negative patients, who are inmunosupressed due to cancer treatment. Two of them started as febrile neutropenia and three as probable Cytomegalovirus co-infection.

BACKGROUND AND PURPOSE: Stroke is the third leading cause of death in Argentina, yet little information exists on the acute treatment provided for stroke or its costs. This study estimates the national costs of the acute treatment of first-ever intracerebral hemorrhage (ICH) and ischemic stroke (IS) in Argentina. METHODS: Retrospective hospital-based inception study design using data on resource use and costs from high-volume stroke centers in Argentina, and published population-based incidence data. Treatment provided at two large urban hospitals were evaluated in all patients admitted with a first-ever stroke between 1 January 2004 and 31 August 2006, and costs were assigned using appropriate unit cost data for all resource use. Cost estimates in Argentinian pesos were converted to US dollars ($) using the 2005 purchasing power parity index. National costs of acute treatment for incident strokes were estimated by extrapolation of average costs estimates to national incidence data. Assumptions of the average cost of stroke treatment on a national scale were examined in sensitivity analysis. RESULTS: The acute care of 167 patients with stroke was thoroughly evaluated from hospital admission to hospital discharge. Mean length of hospital stay was 35.4 days for ICH and 13.0 days for IS. Ninety-one percent of the patients with ICH and 68% of the patients with IS were admitted to an ICU for a mean length of stay (LOS) of 12.9 +/- 20.3 and 3.6 +/- 5.9 days respectively. Mean total costs of initial hospitalization were $12,285 (SD +/-14,336) for ICH and $3888 (SD +/-4018) for IS. Costs differed significantly by Glasgow Coma Scale (GCS) score at admission, development of pneumonia and infections during hospitalization, and functional outcome at hospital discharge. Aggregate national healthcare expenditures for acute treatment of incident ICH were $194.2m (range 97.1-388.4) and $239.9m for IS (range 119.9-479.7). CONCLUSION: The direct hospital costs of incident ICH and IS in Argentina are substantial and primarily driven by stroke severity, in-hospital complications and clinical outcomes. With the expected increase in the incidence of stroke over the coming decades, these results emphasize the need for effective preventive and acute medical care.

BACKGROUND: Previously we observed in some but not all septic patients a low plasma concentration of plasminogen. OBJECTIVES: To investigate prospectively whether plasma levels of plasminogen or the ratio of plasminogen to alpha-2-antiplasmin have a prognostic value for survival from sepsis and to study the variation of other hemostatic parameters during septicemia. PATIENTS: The study population consisted of 45 consecutive patients with septicemia, 15 non-septic patients from the same intensive care unit and 30 healthy volunteers. MEASUREMENTS AND MAIN RESULTS: Plasminogen concentrations were significantly lower (p < 0.001) in plasma of septic patients (median 0,62 IU/ml range: 0.15-1,06) than in plasma of healthy controls (median 1.00 IU/ml, range: 0.75-1.10) or of non-septic intensive care patients (median 1.00 IU/ml, range: 0.82-1.08). Among the other parameters tested, plasminogen activator inhibitor (PAI-1) antigen concentration and PAI activity were similar in septic and non-septic intensive care patients, but higher than in healthy controls. Concentrations of elastase-alpha-1-protease inhibitor or of thrombin-antithrombin complexes were higher in septic patients than in non-septic intensive care patients or healthy controls. A degraded form of plasminogen of 38 kDa was detected by Western blot analysis in the plasma of septic patients, but not in plasma of non-septic intensive care patients or controls. Plasminogen alone or the ratio of plasminogen to antiplasmin were good markers for survival from septicemia. E.g. for plasminogen at a cut off of 0.65 IU/ml, sensitivity was 90.5% and specificity 66.7%, whereas for the ratio of plasminogen over antiplasmin at a cut off ratio of 0,65 IU/ml, sensitivity was 95.2% and specificity 70.8%. CONCLUSION: Plasminogen or the ratio of plasminogen to antiplasmin are sensitive markers for survival in patients with septicemia.

Para evaluar el pronóstico en relación con la mortalidad de los pacientes sometidos a cirugía con circulación extracorpórea se diseñó un puntaje compuesto por 21 ítems que incluyen variables pre, intra y posoperatorias. Los pacientes fueron evaluados con dicho puntaje al ingreso y a las 12 horas del posoperatorio inmediato. Se incluyeron 662 pacientes. Tras realizar el análisis estadístico se observó una diferencia significativa en la mortalidad de los pacientes con puntaje menor de 20 puntos y mayor o igual de 21 puntos. La mortalidad de pacientes con puntaje menor o igual a 20 puntos para cirugías programadas fue del 1,7 por ciento y con más de 20 puntos 36 por ciento (p< 0,00001). La mortalidad de pacientes con puntaje menor o igual a 20 puntos para cirugía de urgencia fue del 5,9 por ciento y de pacientes con puntaje superior a 20 puntos 45,5 por ciento (p< 0,01) (AU)

For many years, the evolution of Argentina's healthcare system has been influenced by political and economic instability. Inflation and hyperinflation have led to anarchic development of both health administration systems and hospitals. Critical care grew in a similar manner, resulting in a mix of > 500 critical care units with very different levels of technology and trained personnel. Cost-containment policies have been implemented mainly by health administration systems. Public institutions (university and large provincial and county hospitals) have suffered hard budget cuts that have resulted in a decrease in the quality of care and the loss of trained human resources. Union organizations, which cover the healthcare costs of > 60% of the population, implemented a low reimbursement policy that resulted in low standards of care for critically ill patients. The country's private hospital system is extremely heterogenous, ranging from little, simple institutions with a 20- to 30-bed capacity to great private institutions with international standards of care. Cost-containment efforts have been sporadic and isolated, and statistical data to analyze the results are lacking. In order to formulate a strategy of cost-containment in the near future, accreditation and categorization of critical care units and human resources training are being implemented by health authorities and the Argentine Society of Critical Care Medicine.
