RESUMO

PURPOSE: Cervical necrotizing fasciitis (CNF) is a severe and debilitating disease that requires intensive care unit (ICU) management and prompt surgical treatment to reduce morbidity and mortality. The aim of this study was to estimate the incidence and factors associated with severe complications of CNF. METHODS: We reviewed the medical records of consecutive patients hospitalized in an ICU from 2007 to 2012. The data were collected retrospectively; initial cervical and thoracic computed tomography (CT) scans, performed on admission, were reviewed by an experienced and blinded radiologist to determine CNF complications. RESULTS: A cohort of 160 patients admitted for CNF was included. The following complications of CNF were found: bilateral extension of CNF (28%), internal jugular vein thrombosis (21%), descending necrotic effusion (14%), mediastinitis (24%), and mortality (4%); 53% had at least one complication, and 48% had at least one cervical complication. On the basis of a univariate analysis, the significant independent factors are odynophagia, dyspnea, oral glucocorticoids intake before admission, and pharyngeal source. Oral nonsteroidal anti-inflammatory drug intake before admission does not have any impact. The initial CNF complications increased both the duration of mechanical ventilation and the length of stay in the ICU. On the basis of a multivariate analysis, the independent factors for severe complications are pharyngeal CNF and oral glucocorticoid intake before admission. CONCLUSIONS: Our study demonstrated that an initial cervico-thoracic CT scan revealed a high incidence of cervical and mediastinal CNF complications that all needed immediate management. Those severe complications might be avoidable as they were associated, at least partially, with prehospital oral glucocorticoid intake.

RESUMO

BACKGROUND: The number of elderly patients proposed for brain tumor removal is increasing. Only few data on long-term functional prognosis after intracranial surgery are available. MATERIALS AND METHODS: Prospective, observational study of all patients greater than 70 year of age operated for intracranial tumors. Two scales for health status evaluation were used: Karnofsky Performance Scale (KPS) and Activities of Daily Living (ADL) score. Data were expressed as medians (first to third quartiles). The primary endpoint was the probability to remain nondependant (ADL>3 and KPS≥70%) after 1 year. RESULTS: Between 2003 and 2007, 90 patients were included: 46 (51.1%) meningioma, 17 (18.9%) high-grade glioma, and 11 (12.2%) metastasis. At hospital admission, age was 73.50 years (71.25-76.00), American Society of Anesthesiology score 2 (2 to 3), KPS 80% (70-90), ADL 5.5 (4.5 to 6.0). Two patients died during the first 28 days, 3 others during the first year. Both KPS and ADL decreased after 1 year: KPS 80% (70 to 90; mean: 80%) at hospital admission versus 80% (60 to 90) at 1 year (mean: 70%), P=0.003; ADL 5.5 (4.5 to 6.0) at hospital admission versus 5.0 (3.25 to 5.50) at 1 year, P=0.001. In multivariate analysis, 2 preoperative parameters were associated with autonomy at 1 year: the ADL at hospital admission and meningioma as histologic type. CONCLUSIONS: In this series of elderly patients, intracranial tumor surgery was associated with low 1-year mortality. Meningioma was associated with a better postoperative functional outcome. Preoperative ADL score was a predictive of functional evolution 1 year after the surgery.

RESUMO

As for other critically ill diseases, two key factors may markedly improved morbidity and mortality of acute heart failure syndromes (AHFS): early initiation of treatment and tailored therapy. Early initiation aims to stop the negative cascade of heart dysfunction. Tailored therapy should be based on the level of systolic blood pressure at admission and fluid retention. Indeed, EFICA and OPTIMIZE-HF showed that patients with high systolic blood pressure have a left ventricular systolic function that is likely preserved and those with low systolic blood pressure have a lower left ventricular ejection fraction and frequent signs of organ's hypoperfusion. Among the proposed treatments, non-invasive ventilation is the only treatment that was consistently proven to be beneficial on morbidity and mortality in almost all types of AHFS. Concerning pharmacological agents, actions should be taken to increase the use of vasodilators and reduce the use of diuretics.

RESUMO

OBJECTIVE: To compare hemodynamic and gasometric variables and the plasma concentrations of nitric oxide metabolites (cyclic guanosine monophosphate and nitrate and nitrite), endothelin-1, and renin-angiotensin metabolites before and after the start of nitric oxide inhalation, after prolonged nitric oxide inhalation, and before and after nitric oxide withdrawal. DESIGN: Prospective study. SETTING: Surgical intensive care unit, university hospital. SUBJECTS: Patients with acute lung injury and right ventricular failure. INTERVENTIONS: Nitric oxide inhalation (10-12 ppm) during a median of 2.9 days (12 hrs to 6.5 days). MEASUREMENTS AND MAIN RESULTS: The pulmonary vasodilator effects of inhaled nitric oxide improved arterial oxygenation in patients with acute lung injury (p < .05) and reduced right atrial pressure in patients with right ventricular dysfunction (p < .01). These beneficial effects lasted the whole period of prolonged inhaled nitric oxide therapy up to 6.5 days. However, when inhaled nitric oxide was withdrawn, pulmonary vasodilator effects rapidly disappeared, and Pao2/Fio2 ratio markedly deteriorated in all studied patients to return to pre-inhaled nitric oxide levels. Changes in plasma cyclic guanosine monophosphate and nitrate and nitrite paralleled those of pulmonary vasodilatory effects. An immediate increase in plasma cyclic guanosine monophosphate with a slightly delayed increase in plasma nitrate and nitrite was observed at inhaled nitric oxide start with no attenuation during the prolonged inhaled nitric oxide therapy. A marked decrease toward pre-inhaled nitric oxide levels was seen within hours of inhaled nitric oxide withdrawal. In addition, no alteration of plasma endothelin-1 or renin-angiotensin mediators was observed during or after inhaled nitric oxide therapy. CONCLUSIONS: Our study showed a lack of attenuation in the beneficial effects of inhaled nitric oxide and a lack of alteration of endogenous nitric oxide, endothelin-1, and renin-angiotensin pathways during prolonged nitric oxide inhalation.
