Background Early diagnostic orientation for differentiating pneumonia from pneumonitis at the early stage after aspiration would be valuable to avoid unnecessary antibiotic therapy. We assessed the accuracy of procalcitonin (PCT) in diagnosing aspiration pneumonia (AP) in intensive care unit (ICU) patients requiring mechanical ventilation after out-of-hospital coma. Methods Prospective observational 2-year cohort study in a medical-surgical ICU. PCT, C-reactive protein (CRP) and white blood cell count (WBC) were measured at admission (H0) and 6 h (H), H12, H24, H48, H96, and H120 after inclusion. Lower respiratory tract microbiological investigations performed routinely in patients with aspiration syndrome were the reference standard for diagnosing AP. Performance of PCT, CRP, and WBC up to H48 in diagnosing AP was compared based on the areas under the ROC curves (AUC) and likelihood ratios (LR+ and LR−) computed for the best cutoff values. Results Of 103 patients with coma, 45 (44%) had AP. Repeated PCT assays demonstrated a significant increase in patients with AP versus without AP from H0 to H120. Among the three biomarkers, PCT showed the earliest change. ROC-AUC values were poor for all three biomarkers. Best ROC-AUC values for diagnosing AP were for CRP at H24 [0.73 (95%CI 0.61–0.84)] and PCT at H48 [0.73 (95%CI 0.61–0.84)]. LR+ was best for PCT at H24 (3.5) and LR− for CRP and WBC at H24 (0.4 and 0.4, respectively). Conclusions Early and repeated assays of PCT, CRP, and WBC demonstrated significant increases in all three biomarkers in patients with versus without AP. All three biomarkers had poor diagnostic performance for ruling out AP. Whereas PCT had the fastest kinetics, PCT assays within 48 h after ICU admission do not help to diagnose AP in ICU patients with coma.

Objective To determine whether routine electroencephalography (EEG) detected electrical status epilepticus (ESE), masked by neuromuscular blockade, in comatose cardiac-arrest survivors receiving therapeutic hypothermia. Design Prospective 3-year study Setting Medical ICU Patients Fifty-one consecutive comatose cardiac-arrest patients treated between May 2005 and May 2008 using a standardized protocol of hypothermia with neuromuscular blockade. Intervention EEG was performed routinely as soon as possible after starting therapeutic hypothermia. EEG recordings were read by an independent neurophysiologist who was blinded to patient data. Measurements and Main Results Median body temperature at EEG recording was 33.0°C (range 32.4–33.8). ESE was found on 5 (10%) of the 51 EEG recordings: three patients had continuous rhythmic generalized spikes and two patients had continuous rhythmic focal spike-waves. Of the 17 (33%) patients who were discharged alive, 8 (8/51, 16%) had a CPC score of 1, 4 (8%) of 2, and 5 (10%) of 3. All patients with ESE died during their ICU stay. Conclusion These preliminary results indicate that postanoxic status epilepticus can be masked by neuromuscular blockade during our protocol of therapeutic hypothermia. Routine EEG monitoring might be helpful in cardiac-arrest survivors receiving therapeutic hypothermia. Further studies including continuous EEG monitoring are needed to determine whether early diagnosis and treatment of ESE during therapeutic hypothermia improves the outcome.

Background Alcohol is the leading psychoactive substance consumed in France, with about 15 million regular consumers. The National institute on Alcohol Abuse and Alcoholism (NIAAA) considers alcohol abuse to be more than 14 units of alcohol a week for men and 7 units for women. The specific complication of alcoholism is the alcohol withdrawal syndrome. Its incidence reaches up to 30 % and its main complications are delirium tremens, restlessness, extended hospital stay, higher morbidity, and psychiatric and cognitive impairment. Without appropriate treatment, delirium tremens can lead to death in up to 50 % of patients. Methods/design This prospective, double-blind, randomised controlled study versus placebo will be conducted in twelve French intensive care units (ICU). Patients with an alcohol intake level higher than the NIAAA threshold, who are under mechanical ventilation, will be included. The primary objective is to determine whether baclofen is more efficient than placebo in preventing restlessness-related side effects in the ICU. Secondary outcomes include mechanical ventilation duration, length of ICU stay, and cumulative doses of sedatives and painkillers received within 28 days of ICU admission. Restlessness-related side effects in the ICU are defined as unplanned extubation, medical disposal removal (such as urinary catheter, venous or arterial line or surgical drain), falling out of bed, ICU runaway (leaving ICU without physician's approval), immobilisation device removal, self-aggression or aggression towards medical staff. Daily doses of baclofen/placebo will be guided by daily creatinine clearance assessment. Discussion Restlessness in alcoholic patients is a life-threatening issue in ICUs. BACLOREA is a randomised study assessing the capacity of baclofen to prevent agitation in mechanically ventilated patients. Enrolment of 314 patients will begin in June 2016 and is expected to end in October 2018. Trial registration ClinicalTrials.gov Identifier: NCT02723383 , registered on 3 March 2016.

Introduction Takotsubo cardiomyopathy can complicate several conditions including neurological emergencies. A few recurrent cases associated with seizures have been reported, but none of the patients had status epilepticus. The pathophysiology of takotsubo syndrome, although debated, may involve stunning of the myocardium by a catecholamine storm triggered by stress. Patients with epilepsy may be at increased risk for takotsubo syndrome, which may occur repeatedly. Methods We report on a postmenopausal woman with symptomatic epilepsy who experienced recurrent takotsubo cardiomyopathy triggered by convulsive status epilepticus. Brief seizures were not associated with takotsubo syndrome. The relevant literature was reviewed. Results Over a 1-year period, she experienced two episodes of convulsive status epilepticus with complete neurological recovery after treatment. Echocardiography showed latero-septo-apical hypokinesia and apical ballooning. The cardiac abnormalities resolved fully and she recovered her baseline level of self-sufficiency. During the same period, she experienced several brief seizures, with no cardiac manifestations. Conclusion The occurrence of takotsubo cardiomyopathy in association with convulsive status epilepticus, but not with brief seizures, supports neurogenically mediated myocardial stunning related to direct toxicity of endogenous catecholamines. Neuro-intensivists must be aware of this potentially fatal but fully reversible cardiac complication, which may be among the causes of death in patients with status epilepticus.

Background Alcoholic hand rubs (AHRs) have been proven effective in preventing nosocomial infections, and healthcare authorities include AHRs use among quality-of-care criteria. Since the onset of the influenza A (H1N1) pandemic, AHRs have gained considerable popularity among the general public. Methods We report a case of intentional AHRs self-poisoning inducing rapid coma with hyperlactatemia, and a full recovery. The relevant literature was reviewed. To our knowledge, this is the third reported case of intentional AHRs poisoning. 3 patients presented with a picture of acute alcohol intoxication, of variable severity depending on the amount ingested and speed of ingestion. Results The blood alcohol level was 414 mg/dl and tests for other drugs were performed 30 min after admission. The blood lactate level increased briefly to 4.8 mmol/l, without renal or hepatic function disturbances. She regained consciousness after 6 h then achieved a full recovery allowing extubation and readmission to the psychiatric ward after 24 h. She reported gulping down the entire contents of the Aniosgel ® bottle. Conclusion Whereas overdrinking in social settings (wine and liquor) leads to a gradual increase in blood alcohol levels, AHRs poisoning is usually characterized by a sudden massive alcohol load. The unusual nature of the alcohol source may lead to diagnostic wanderings. AHRs are currently available in bottles that facilitate the ingestion of large amounts. Unit-dose packaging or dispensing might decrease the risk of AHRs poisoning.

Introduction Posterior reversible encephalopathy syndrome (PRES) is known to occur in association with several substances. However, lysergic acid amide (LSA) is not among the previously reported causes of PRES. Methods We report on a patient with PRES presenting as convulsive status epilepticus associated with hypertensive encephalopathy after LSA ingestion. Magnetic resonance imaging was performed and catecholamine metabolites assayed. Results The patient achieved a full recovery after aggressive antihypertensive therapy and intravenous anticonvulsivant therapy. The clinical history, blood and urinary catecholamine levels, and response to treatment strongly suggest that PRES was induced by LSA. Conclusion LSA, a hallucinogenic agent chiefly used for recreational purposes, should be added to the list of causes of PRES.
