Le kyste hydatique du foie (KHF) est une maladie assez répandue dans les pays nord-africains. La rupture post-traumatique ou spontanée du kyste compliquée d'un choc anaphylactique et d'un AVC ...ischémique a été exceptionnellement rapportée. Nous rapportons un cas d'un kyste hydatique du foie (KHF) fissuré et compliqué d'un choc anaphylactique et d'un AVC ischémique.
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).
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.
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.
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.
Posterior reversible encephalopathy syndrome (PRES) is an acute central nervous system disorder characterized by reversible brain vasogenic edema. We report here a new case of a nine-year-old boy ...with B-cell acute lymphoblastic leukemia (B-ALL) who developed PRES secondary to induction chemotherapy including dexamethasone (dexamethasone®), vincristine (oncovin(®)), daunorubicin (adriblastine(®)) and intrathecal injection. Cerebral magnetic resonance imaging (MRI) showed high signal intensity on T2 at cortical and sub cortical region of parieto-frontal and parieto-occipital lobes. The patient was put under sodium valproate (depakine(®)) and we decided to continue dexamethasone (dexamethasone(®)) and daunorubicin (adriblastine(®)) injection. The MRI, after four weeks, was normal. So, we resumed vincristine (oncovin(®)) and we started L-asparaginase injections. Then, the outcome was favorable. The treatment of PRES is based on the withdrawal of the triggering factor to avoid the risk of irreversible lesions. But, due to the severity of leukemia the discontinuation of chemotherapy is difficult because of the risk of disease progression.
In all cases, bacterial cultures of blood, urine, and sputum were negative. ...atypical respiratory pathogens such as Mycoplasma pneumoniae, Coxiella burnetti, and Chlamydia pneumoniae coinfection ...were ruled out by a negative serologic reaction. ...serologic reaction for Legionella pneumophila was not performed in all cases because this atypical respiratory pathogen is rarely observed in our country. ...therapy with oseltamivir and steroids in addition to empiric antibiotics was commenced.
To determine predictive factors of mortality among children after isolated traumatic brain injury.
In this retrospective study, we included all consecutive children with isolated traumatic brain ...injury admitted to the 22-bed intensive care unit (ICU) of Habib Bourguiba University Hospital (Sfax, Tunisia). Basic demographic, clinical, biochemical, and radiological data were recorded on admission and during ICU stay.
There were 276 patients with 196 boys (71%) and 80 girls, with a mean age of 6.7 ± 3.8 years. The main cause of trauma was road traffic accident (58.3%). Mean Glasgow Coma Scale score was 8 ± 2, Mean Injury Severity Score (ISS) was 23.3 ± 5.9, Mean Pediatric Trauma Score (PTS) was 4.8 ± 2.3, and Mean Pediatric Risk of Mortality (PRISM) was 10.8 ± 8. A total of 259 children required mechanical ventilation. Forty-eight children (17.4%) died. Multivariate analysis showed that factors associated with a poor prognosis were PRISM > 24 (OR: 10.98), neurovegetative disorder (OR: 7.1), meningeal hemorrhage (OR: 2.74), and lesion type VI according to Marshall tomographic grading (OR: 13.26).
In Tunisia, head injury is a frequent cause of hospital admission and is most often due to road traffic injuries. Short-term prognosis is influenced by demographic, clinical, radiological, and biochemical factors. The need to put preventive measures in place is underscored.
BACKGROUNDVenous thromboembolism (VTE) is a well-established complication of trauma. Recent studies suggest that pulmonary embolism (PE) may occur very early, and even immediately, after injury. The ...aim of this study is to analyze the incidence, risk factors and prognosis of early PE among ICU trauma patients. PATIENTS AND METHODSWe conducted a twenty-month-long prospective cohort study, including all trauma patients with a confirmed PE diagnosis admitted to our ICU between January 1st, 2017 and August 31st, 2018. Early post traumatic PE was defined as pulmonary embolism diagnosed within the first 72 hrs of injury. All the patients who were included were systematically screened for early PE on day 3. RESULTSDuring the study period, 365 trauma patients were admitted. The diagnosis of post-traumatic PE was confirmed in 66 patients (18%). In our study, 27 patients (41.5%) developed a PE within 72 hrs of trauma. According to our analysis, the factors associated with the development of early post-traumatic PE in multivariate analysis were obesity (P=0.049; OR=4.04), high SOFA score (P=0.003; OR=1.67), and the use of surgical procedures (P=0.033; OR=4.87). Furthermore, sepsis and ventilator-acquired pneumonia were associated with late PE (P=0.019; OR=5.87). Overall, the mortality rate was at 19.7%. Yet, the patients who were diagnosed with early PE had a higher mortality rate compared to the late PE group (33% vs. 10.2%, respectively). We found that the only independent predictive factor of mortality among the patients with early post-traumatic PE included in this study was the APACHEII score on ICU admission (P=0.011; OR=1.44). CONCLUSIONOur study cohort showed that many of the post-traumatic PEs occur early in the post-traumatic period. To the best of our knowledge, this is the first prospective study conducted in an ICU to apply a systematic screening protocol for post-traumatic PE diagnosis. Further studies with larger patient populations are required to create more accurate predictive models.
Purpose
to evaluate the current rate of pulmonary embolism (PE) in our medico‐surgical intensive care unit (ICU), to identify risk factors, and to determine the outcome of PE in ICU.
Methods
We ...performed a prospective cohort study of consecutive patients requiring intensive care admission during a one‐year period. We included, in this prospective study, all the patients with confirmed PE admitted in ICU with more than 18 years of age, and expected to stay in ICU for more than 48 hours. Only the patients who had a clinical suspicion (unexplained hypoxemia and/or shock) for PE underwent diagnostic studies.
Results
During the study period, 842 patients were admitted in our ICU. One hundred and two patients were excluded. The diagnosis of PE was confirmed in 75 patients (10.1%). In our study, all patients (100%) had received some forms of pharmaceutical prophylaxis (PP) during ICU stay. The median time from ICU admission to diagnosis of PE was 6 days. The diagnosis of PE was made by spiral CT in 74 patients (98.7%), and by echocardiography in 1 case (1.3%). The mean ICU stay was 26.3 ± 26.5 days (median: 20 days). During their ICU stay, 73 patients (97.3%) developed one, or more, organ failure. Respiratory failure was the most observed (97.3%). Moreover, 38 patients (50.6%) developed nosocomial infections and 29 (38.6%) died. The multivariate analysis showed that the risk factors associated with mortality were the presence of shock the day of PE diagnosis and the presence of right ventricular dilatation on echocardiography.
Conclusion
Our findings confirm that subjects in the ICU are at high risk of PE, due to a high number of risk‐factors. PE was associated with higher ICU mortality and a significantly higher ICU LOS. Our results invite to revise the preventive strategies of deep venous thrombosis and PE in patients requiring ICU admission.
