ABSTRACT
Tracheostomy cannula care is of paramount importance in the daily management of tracheotomized patients. While some complications are commonplace, specific events can occur, often according to type of cannula. We herein report the case of a 71-year-old patient; following a lengthy stay in the intensive care unit, she had received a Safe T-Tube cannula designed to provide support in a stenotic trachea. At home, while suctioning her tracheal secretions, she suddenly experienced respiratory distress requiring a rapid intervention. On arrival, no seeable cannula was found, either in the tracheostomy or in the patient's immediate surroundings. Following her transfer to intensive care, a new cannula was inserted into the tracheostomy opening, enabling mechanical ventilation to begin and achieving rapid relief of dyspnea and improvement of the patient's overall condition. Bronchial fibroscopy was then performed, during which the Safe T-Tube cannula was found folded on itself in a supra-carinal intra-tracheal position. It was extracted and replaced by a cannula of the same model, which was sewn to the skin. Although rare and usually limited to flexible cannulas, this complication is potentially fatal. Generally speaking, when cannula obstruction is suspected, bronchial endoscopy in an intensive care setting is a vital necessity. It is not only the cornerstone of the diagnosis, but also of paramount importance in treatment taking into full account the mechanism of obstruction.

INTRODUCTION: Leptospirosis is a worldwide zoonosis responsible for highly diverse clinical presentations with a wide range of severity. Variable environment exposures to infected urines of rodents have been described. OBSERVATION: We report five cases of serologically confirmed leptospirosis leading to hospitalization in an intensive care unit (ICU) of a French center. These patients displayed neurological, respiratory, and abdominal presentation of leptospirosis with variable level of severity. Either professional, leisure related, or daily living exposures have been retrieved. CONCLUSION: These cases underline the diversity of clinical presentation and environmental exposure of this infectious disease. They highlight the interest of an exhaustive anamnesis with collection of professional activity, environmental exposures, and leisure activities.

BACKGROUND: Extracorporeal carbon dioxide removal (ECCO2R) is a promising technique for the management of acute respiratory failure, but with a limited level of evidence to support its use outside clinical trials and/or data collection initiatives. We report a collaborative initiative in a large metropolis. METHODS: To assess on a structural basis the rate of utilization as well as efficacy and safety parameters of 2 ECCO2R devices in 10 intensive care units (ICU) during a 2-year period. RESULTS: Seventy patients were recruited in 10 voluntary and specifically trained centers. The median utilization rate was 0.19 patient/month/center (min 0.04; max 1.20). ECCO2R was started under invasive mechanical ventilation (IMV) in 59 patients and non-invasive ventilation in 11 patients. The Hemolung Respiratory Assist System (Alung) was used in 53 patients and the iLA Activve iLA kit (Xenios Novalung) in 17 patients. Main indications were ultraprotective ventilation for ARDS patients (n = 24), shortening the duration of IMV in COPD patients (n = 21), preventing intubation in COPD patients (n = 9), and controlling hypercapnia and dynamic hyperinflation in mechanically ventilated patients with severe acute asthma (n = 6). A reduction in median V T was observed in ARDS patients from 5.9 to 4.1 ml/kg (p <0.001). A reduction in PaCO2 values was observed in AE-COPD patients from 67.5 to 51 mmHg (p< 0.001). Median duration of ECCO2R was 5 days (IQR 3-8). Reasons for ECCO2R discontinuation were improvement (n = 33), ECCO2R-related complications (n = 18), limitation of life-sustaining therapies or measures decision (n = 10), and death (n = 9). Main adverse events were hemolysis (n = 21), bleeding (n = 17), and lung membrane clotting (n = 11), with different profiles between the devices. Thirty-five deaths occurred during the ICU stay, 3 of which being ECCO2R-related. CONCLUSIONS: Based on a registry, we report a low rate of ECCO2R device utilization, mainly in severe COPD and ARDS patients. Physiological efficacy was confirmed in these two populations. We confirmed safety concerns such as hemolysis, bleeding, and thrombosis, with different profiles between the devices. Such results could help to design future studies aiming to enhance safety, to demonstrate a still-lacking strong clinical benefit of ECCO2R, and to guide the choice between different devices.

ABSTRACT
Widespread vaccination has largely eliminated anthrax in Europe (the last case was reported in France in 1972) but the disease remains endemic in many developing countries. The usual cutaneous presentation (malignant pustules) is much more familiar than the various visceral manifestations including digestive tract, pulmonary or meningeal signs. We report a case of a 33-year-old immigrant living in France who was hospitalized for asthenia, dyspnoea, mucopurulant expectoration and moderate diarrhoea 3 days after a 3-month stay in Senegal and Gambia. The temperature was 39 degrees C at admission and blood pressure 110/70 mmHg. Crepitants were heard at the base of the right lung and the rest of the physical examination was normal. Blood was drawn for culture. Laboratory tests and the chest X-ray led to the diagnosis of pneumopathy and a treatment of amoxicillin and clavulanic acid was given with oxygenotherapy. The patient's temperature returned to normal but over the next 48 hours the dyspnoea worsened together with the black diarrhoea. The abdomen was painful. There were no skin lesions. The chest X-ray revealed an extension of the bilateral pulmonary images and bilateral pleural effusion. Laboratory tests revealed thrombopenia (platelet count 38,000/mm3) hyperleukocytosis (WBC 48,000/mm3) and haemolysis (Hb 4 milligrams). The diagnosis was made on the basis of the initial blood cultures which were positive for Bacillus anthracis. All other samples were negative, including HIV serology. Despite adapted antibiotic therapy (penicillin G, 8MU/day, was initiated on day 2), multiple organ failure occurred with septic shock and pulmonary oedema. The patient died in the intensive care unit on day 7. Fatal outcome due to anthrax is described in 25% of the visceral forms but reaches 100% in cases of septicaemia. The haemolysis observed in this case is not mentioned in the classical descriptions of anthrax. When treating septic syndromes in patients who have returned from endemic zones, clinicians should entertain the diagnosis of anthrax since the risk of fatal outcome is increased greatly in case of delayed diagnosis.

A case of toxic epidermolysis (TE) with a fatal outcome is reported. It occurred after administration of 500 mg griseofulvin twice daily in a 19-year-old female patient. She developed the first skin lesions on the sixth day of treatment. All the body surface was involved, except for the scalp. Several complications arose in the course of the disease, thrombocytopaenia, lymphocytopaenia, rhabdomyolysis, and non cardiogenic pulmonary oedema. Death occurred as a result of multiple organ failure following septic shock associated with adult respiratory distress syndrome. The pathogenesis of these complications and the major therapeutic difficulties encountered are discussed. The involvement of griseofulvin in TE has only been reported once before. The arguments in favour of its involvement in the present case are discussed.

Colonization of central catheter tips has been associated with catheter-related infections. This colonization is defined as the presence of over 15 CFU in a semiquantitative catheter tip culture performed after catheter removal. Using a simple pour-plate technique, we determined the microbial concentrations in samples of blood collected via the hubs of 205 central catheters while they were in position in 179 cancer patients. All catheters were removed within three days of blood collection via the hub and cultured semiquantitatively. We then compared the results for the hub blood cultures and catheter tip cultures. Cultures from 18% of the hub samples and 29% of the tips were positive. When a cutoff limit of 1,000 CFU/ml was used for the blood cultures, the sensitivity was 20% and the specificity was 99% for estimating catheter tip colonization. These values did not seem to be related to the underlying disease, the site of catheter insertion, or the antibiotic treatment administered at catheter removal. We conclude that, if positive, cultures of blood sampled via the catheter hub can be useful in assessing the risk of catheter colonization in cancer patients.
