RESUMEN
Cocoon abdomen is an uncommon condition characterized by bowel entrapment in a cocoon-like membrane. Its clinical presentation is usually non-specific. Rarely, it may present with perforation peritonitis. The therapeutic approach depends on the stage of the disease. Surgery is essentially reserved for those with acute surgical complications.

The aim of this study is to analyze if the infusion of hydrocortisone hemisuccinate improve outcome in severe scorpion-envenomated adult patients admitted to intensive care unit (ICU). Pairwise retrospective case-control study with 1:1 matching was designed. Patients were defined as cases when they received hydrocortisone hemisuccinate (as alone steroids) during hospitalization and as controls when they did not received any steroids. Patients were matched according to age, severity factors at admission represented by the presence of pulmonary edema and grades of severity of scorpion envenomation, and scorpion antivenom administration. Eighty-four patients were included as follows: 42 patients in the cases group and 42 patients in the control group. The mean age (±SD) was 40±21 years, ranging from 16 to 90 years. Moreover, 67 (80%) patients have a systemic inflammatory response syndrome on ICU admission. The comparison between cases group and control group showed that age is not significantly different. There were the same proportions of patients with pulmonary edema in 2 groups. Moreover, 23 (54%) patients in case group and 23 (54%) in the control group received scorpion antivenom (P>0.05). The mean temperature on admission was also not significantly different. The presence of systemic inflammatory response syndrome was again not significantly different between 2 groups. The comparison of outcome of the 2 groups showed that the use of mechanical ventilation and its duration, the ICU stay length, and ICU mortality was not significantly different between the 2 groups. Although our study has some limitations, it confirms that the use of hydrocortisone hemisuccinate in severe scorpion-envenomed patients did not improve their outcome.

OBJECTIVE: To assess the predictive factors of ventilator associated pneumonia (VAP) occurrence following open tracheotomy in trauma patients. MATERIALS AND METHODS: We conducted an observational, prospective study over 15 months, between 01/08/2010 and 30/11/2011. All trauma patients (except those with cervical spine trauma), older than 15 years, undergoing open tracheotomy during their ICU stay were included. All episode of VAP following tracheotomy were recorded. Predictive factor of VAP onset were studied. RESULTS: We included 106 patients. Mean age was 37.9 ± 15.5 years. Mean Glasgow coma Scale (GCS) was 8.5 ± 3.7 and mean Injury Severity Score (ISS) was 53.1 ± 23.8. Tracheotomy was performed for 53 patients (50%) because of prolonged ventilation whereas 83 patients (78.3%) had tracheotomy because of projected long mechanical ventilation. Tracheotomy was performed within 8.6 ± 5.3 days. Immediate complications were bleeding events (22.6%) and barotrauma (0.9%). Late complications were stomal infection (28.3%) and VAP (52.8%). In multivariate analysis, independent factors predicting VAP onset were delayed tracheotomy (OR = 0.041; CI95% [1.02-7.87]; P = 0.041) and stomal infection (OR = 3.04; CI95% [1.02-9.93]; P = 0.045). Thirty three patients died in ICU (31.1%) without significant impact of VAP on mortality. CONCLUSION: Late tracheotomy and stomal infection are independent factors predicting VAP onset after open tracheotomy in trauma patients. The occurrence of VAP prolongers mechanical ventilation duration and intensive care unit (ICU) length of stay (LOS) but doesn't increase mortality.
RESUMEN
The purpose of this study was to analyze the efficacy of corticosteroids in severe acute decompensation of chronic obstructive pulmonary disease requiring mechanical ventilation and intensive care unit (ICU) admission. Pairwise retrospective case-control study with 1:1 matching. Patients were defined as cases when they received corticosteroids and as controls when they did not received any steroids. Patients were matched according to age, severity factors at admission represented by the PaO2/FiO2 ratio, and simplified acute physiology score. Thirty-four patients were included. There were 17 patients in the case group and 17 patients in the control group. There were 27 men (80%) and 7 women (20%). The mean age (±SD) was 70 ± 9 years with a range of 40-85 years. Thirty-two patients (94 %) were older than 60 years. The comparison between the 2 groups showed that they had the same epidemiological, clinical, and biological findings on ICU admission. Homodynamic parameters were also not significantly different between the 2 groups. Moreover, there is the same proportion of invasive mechanical ventilation use in 2 groups. Concomitant drugs used were also not significantly different between the 2 groups. Finally, the comparison of outcome between the steroid and steroid-free groups showed that mortality rate was not significantly different (64% vs. 58%, P = 0.72). However, systemic corticosteroid therapy was associated with a significant increase in a reduction in the duration of mechanical ventilation (P = 0.004) and a trend toward a shorter length of ICU stay (P = 0.053). Although the authors detected no significant difference in mortality rate at the time of discharge between steroid and streroid-free patients, this study confirms that systemic corticosteroid therapy in patients with chronic obstructive pulmonary disease exacerbations requiring mechanical ventilation is associated with a significant reduction in the duration of mechanical ventilation. Other studies are needed on this subject.

OBJECTIVES: To report an outbreak due to Providencia stuartii isolates carrying bla(OXA-48), bla(PER-1), bla(CMY-4) and qnrA6 in a Tunisian hospital in 2011. METHODS: Eight intensive care unit (ICU) patients infected/colonized by extended-spectrum ß-lactamase (ESBL)-producing P. stuartii between March and May 2011 were included. Molecular epidemiology was studied by PFGE. Antibiotic resistance genes were analysed by PCR and sequencing and the plasmid incompatibility group by a PCR-based replicon typing scheme. RESULTS: Eight patients were colonized with ESBL-producing P. stuartii isolates. All these isolates were clonally related and found to carry bla(OXA-48), bla(PER-1), bla(CMY-4), qnrA6 and aac-6'-Ib genes on the same self-conjugative IncA/C plasmid. The same strain was also cultured from environmental samples in the ICU. All these isolates were susceptible to carbapenems. Only one colonized patient developed P. stuartii pleurisy and was effectively treated with imipenem alone. CONCLUSIONS: This is the first report of an outbreak due to P. stuartii isolates carrying bla(OXA-48) in Tunisia. The simultaneous expression of various resistance genes (bla(OXA-48), bla(CMY-4), bla(PER-1), qnrA and aac-6'-Ib) by P. stuartii isolates is alarming.

OBJECTIVE: To determine the predictive factors, clinical manifestations, and the outcome of patients with post-traumatic pulmonary embolism (PE) admitted in the intensive care unit (ICU). METHODS: During a four-year prospective study, a medical committee of six ICU physicians prospectively examined all available data for each trauma patient in order to classify patients according to the level of clinical suspicion of pulmonary thromboembolism. During the study period, all trauma patients admitted to our ICU were classified into two groups. The first group included all patients with confirmed PE; the second group included patients without clinical manifestations of PE. The diagnosis of PE was confirmed either by a high-probability ventilation/perfusion (V/Q) scan or by a spiral computed tomography (CT) scan showing one or more filling defects in the pulmonary artery or its branches. RESULTS: During the study period, 1067 trauma patients were admitted in our ICU. The diagnosis of PE was confirmed in 34 patients (3.2%). The mean delay of development of PE was 11.3 ± 9.3 days. Eight patients (24%) developed this complication within five days of ICU admission. On the day of PE diagnosis, the clinical examination showed that 13 patients (38.2%) were hypotensive, 23 (67.7%) had systemic inflammatory response syndrome (SIRS), three (8.8%) had clinical manifestations of deep venous thrombosis (DVT), and 32 (94%) had respiratory distress requiring mechanical ventilation. In our study, intravenous unfractionated heparin was used in 32 cases (94%) and low molecular weight heparin was used in two cases (4%). The mean ICU stay was 31.6 ± 35.7 days and the mean hospital stay was 32.7 ± 35.3 days. The mortality rate in the ICU was 38.2% and the in-hospital mortality rate was 41%. The multivariate analysis showed that factors associated with poor prognosis in the ICU were the presence of circulatory failure (Shock) (Odds ratio (OR) = 9.96) and thrombocytopenia (OR = 32.5).Moreover, comparison between patients with and without PE showed that the predictive factors of PE were: Age > 40 years, a SAPS II score > 25, hypoxemia with PaO(2)/FiO(2) < 200 mmHg, the presence of spine fracture, and the presence of meningeal hemorrhage. CONCLUSION: Despite the high frequency of DVT in post-traumatic critically ill patients, symptomatic PE remains, although not frequently observed, because systematic screening is not performed. Factors associated with poor prognosis in the ICU are the presence of circulatory failure (shock) and thrombocytopenia. Predictive factors of PE are: Age > 40 years, a SAPS II score > 25, hypoxemia with PaO(2)/FiO(2) < 200, the presence of a spine fracture, and the presence of meningeal hemorrhage. Prevention is highly warranted.
RESUMEN
BACKGROUND: Diffuse axonal injury (DAI) is usually associated to severe trauma. Recent imaging advances made its diagnosis easier. Its prognosis impact is not yet well established. The aim of this article is to describe the epidemiologic, clinical, and radiologic features of posttraumatic DAI and to study its prognosis impact on mortality and outcome according to Glasgow Outcome Scale. METHODS: This is a retrospective study over a 4-year period (2004-2007) of 124 patients admitted for head trauma. Demographic, clinical, biological, and radiologic findings were recorded at admission and during intensive care unit stay. RESULTS: Mean age (±standard deviation) was 28 years±15.8 years. Cranial computed tomography scan was sufficient enough to diagnose DAI in 31 patients. Magnetic resonance imaging was performed in 105 patients with a delay of 7.7 days±8.6 days. Most patients were classified as stage II (49.5%) or stage III (44.8%) according to Gentry's classification. In a multivariate analysis, factors associated with higher mortality were dysautonomia (p=0.018; odds ratio [OR]=4.17), hyperglycemia≥8 mmol/L (p=0.001; OR=3.84) on intensive care unit admission, and subdural hematoma (p=0.031; OR=3.99), whereas factors associated to poor outcome according to Glasgow Outcome Scale score were Glasgow Coma Scale score<8 (p=0.032, OR=3.55), secondary systemic injuries score≥3 (p=0.034, OR=2.83), hyperglycemia≥8 mmol/L (p=0.002, OR=5.55), and DAI count≥6 (p=0.035, OR=3.33). In patients with pure DAI, the absence of consciousness recovery was the unique independent factor of mortality (p<0.001, OR=116.4), whereas only transfusion need was an independent factor of poor outcome (p=0.017, OR=4.44). CONCLUSION: Dysautonomia, hyperglycemia, and subdural hematoma are the main factors associated to higher mortality when DAIs are diagnosed, whereas a DAI count≥6 is associated to poor outcome. Magnetic resonance imaging classification did not have a prognosis value even in patients with pure DAI.
