[Perioperative management of a patient with an acquired von Willebrand syndrome]. / Gestion périopératoire d'un patient porteur d'un syndrome de von Willebrand acquis.

We report the case of a man suffering from a monoclonal gammapathy with an acquired von Willebrand disease in a perioperative context. This pathology is rare, but is important to diagnose because of the possible haemorrhagic complications encountered. We describe the main therapeutic options available today to prevent bleeding during major surgery.

[Fast track rehabilitation in colonic surgery]. / Réhabilitation rapide en chirurgie colique.

In France, the total hospital stay after colorectal resection by laparoscopy or laparotomy varies between 10 and 20 days. For several years, the concept of fast track rehabilitation in colonic surgery has been developed. In addition to a specific surgical and anaesthetic management, this concept relies on postoperative measures, particularly an early food intake and ambulation, which allow a spectacular reduction of the hospital stay to only 2 days. Two remarks temper initial optimism: all patients do not wish a short hospital stay and the wards do not always have the available resources necessary to set up this concept.

[An unusual cause of acute respiratory distress: obstructive bronchial aspergillosis]. / Une cause inhabituelle de détresse respiratoire aiguë: l'aspergillose bronchique obstructive.

We report the case of a 77-Year-old immunocompetent woman who required intensive care for acute dyspnea revealing complete atelectasia of the left lung related to an aspergillus mycelium plug blocking the principal bronchus. The clinical course was favorable after deobstruction by thermocoagulation and oral itraconazole given for six Months. The patient was free of parenchymatous or endobronchial sequelae. Adjuvant oral corticoid therapy was given temporarily during the second Month of treatment when signs of transition towards allergic aspergillosis developed. Four Months after discontinuing the antifungal treatment, the patient developed a new episode of acute dyspnea caused by atelectasia limited to the right lower lobe. Treatment by itraconazole was resumed and continued as long-term therapy. No recurrence has been observed for eighteen Months. The diagnostic and therapeutic problems raised by Aspergillus fumigatus are well known in the immunocompromised subject, but can also be encountered in the immunocompetent subject.

[Acute poisoning by chemical warfare agent: sulfur mustard]. / Intoxication aiguë par arme chimique vésicante: l'ypérite.

OBJECTIVE: To review story, mechanism of action, clinical and therapeutic bases of a sulfur mustard poisoning, by accidental, terrorism or war exposure. DATA SOURCES: References were obtained from computerised bibliographic research (Medline), from personnel data (academic memoir, documents under approbation of the National Defense Office) and from the Library of Military Medical Service. DATA SYNTHESIS: Sulfur mustard is a chemical warfare agent with peace time results: leak, accidental handling, acts of terrorism. Sulfur mustard is a vesicant agent, an organochlorine agent, who alkylate DNA. Under liquid or gas form its main target are skin and lungs. Clinical effects are like burns with loss of immunity, with respiratory failure, ophthalmic, gastrointestinal and haematological signs. The last studies have improved knowledge about the mechanism of action, detection, protection and treatment. Methods for determination of sulfur mustard are based on gas chromatographic method and mass spectrometry. During sulfur mustard contamination the first priorities of treatment are to remove victims from the contaminated place and to initiate decontamination. Emergency workers and materials must take protection to avoid secondary contamination of emergency unit. With treatment of vital functions and respiratory failure, the new ways of treatment are about N-acetyl cysteine for lung injury, poly (ADP-ribose) polymerase inhibitors, calmodulin antagonists and Ca(++) chelators. Interactions between sulfur mustard and anaesthetic agents are not well known and are based on clinical observations. CONCLUSION: Emergency care unit can be confronted with sulfur mustard during accidental contamination or acts of terrorism. First and most efficacy priorities of treatment are to remove and to decontaminate victims. New means of detection and treatment are studied since several years but are not still appropriate to human victims or mass treatment.

[Implanted automatic defibrillator after ventricular fibrillation treated with semi-automatic defibrillation]. / Défibrillateur automatique implanté après fibrillation ventriculaire traitée par défibrillation semi-automatique.

We report two cases of out-of-hospital ventricular fibrillation treated without delay, with basic life support practiced by the witness, followed by a successful defibrillation by paramedics with a semi-automatic defibrillator. In the subsequent month, a cardioverter-defibrillator was implanted. In one patient, a ventricular tachycardia occurring 10 months later and a ventricular fibrillation 9 months later in the other respectively, were successfully reversed by the implanted defibrillator. These two cases illustrate the value of the "survival chain" concept (undelayed alert, basic life support by witness, early defibrillation by paramedics with a semi-automatic defibrillator, advanced life support by a physician) as well as the benefit of the implanted cardioverter-defibrillator.
