Abstract
OBJECTIVE To determine the efficacy and safety of using natural platelet-activating factor receptor antagonist (PAFra), BN 52021, to treat patients with severe Gram-negative bacterial sepsis. DESIGN A prospective, randomized, double-blind, placebo-controlled, multicenter clinical trial. SETTING Fifty-nine academic medical center intensive care units in Europe. PATIENTS Six hundred nine patients with severe sepsis, suspected to be related to Gram-negative bacterial infection, who received PAFra or placebo. INTERVENTIONS Patients were randomized to receive either a dose of PAFra (120 mg iv) every 12 hrs over a 4-day period or placebo over a 4-day period. MEASUREMENTS AND MAIN RESULTS The patients were well matched at study entry for severity of illness and for risk factors known to influence the outcome of sepsis. Among all randomized patients, the 28-day, all-cause mortality rate was 49% (152/308) in the placebo group, and 47% (140/300) in the PAFra group (p=.50). When analyzed on the basis of the previously defined target population, the 28-day, all-cause mortality rate was 50% (115/232) in the placebo group and 44% (94/212) in the PAFra group, yielding a 12% reduction in mortality rate (p=.29). In patients with documented infection involving other organisms, there was no difference between treated and placebo groups. When the outcomes of organ dysfunctions were examined in the overall population and in the documented Gram-negative bacterial infection population, the number of patients who resolved hepatic dysfunction tended to be higher in the treated group than in the placebo group (p=.06). The number of adverse events reported were not different between the two groups. CONCLUSIONS A 4-day administration of the studied PAFra (BN 52021) failed to demonstrate a statistically significant reduction in the mortality rate of patients with severe sepsis suspected to be related to Gram-negative bacterial infection. If PAFra treatment has any therapeutic activity in severe Gram-negative bacterial sepsis, the incremental benefits are small and will be difficult to demonstrate in a patient population as defined by this clinical trial.

Abstract
UNLABELLED During hypoxemia, hypoxic pulmonary vasoconstriction and tachycardia are often observed in association with increases in pulmonary artery pressure and cardiac output. Nevertheless, the hemodynamic consequences of hypoxemia have never been evaluated by echocardiography and simultaneously compared with invasive hemodynamic variables. Fourteen open-chest, anesthetized piglets (weight 29-36 kg) were submitted to progressive hypoxemia and reoxygenation. Usual invasive hemodynamic variables were obtained from peripheral and central heart catheters. Direct epicardial echocardiography was used to measure right and left ventricular areas on a short-axis view at mid-papillary level. The mean pulmonary artery pressure (MPAP) increased with pulmonary vascular resistance in a dose-related manner as the fraction of inspired oxygen (FIO2) declined from 0.5 to 0.12. The MPAP correlated with right ventricular end-diastolic area (RVEDA) only at FIO2 0.08. There was a 49% reduction in left ventricular end systolic wall stress (LVESWS) between FIO2 0.5 and 0.08. Left ventricular ejection fraction area (LVEFA) increased by 33% above baseline and correlated with the decrease in LVESWS. No correlation was observed between left ventricular end-diastolic area and pulmonary artery occlusion pressure or left atrial pressure and between cardiac output and LVEFA. Systemic vascular resistance underestimates the magnitude of changes in LVESWS but overestimates the afterload compared with LVESWS. This study demonstrates that, for the lowest FIO2 (0.08), changes in MPAP correlated with changes in RVEDA but not in pulmonary vascular resistance. Moreover, LVESWS decreases significantly in a dose-related manner under progressive hypoxemia and normalizes immediately after reoxygenation. This study also shows that, under hypoxemic conditions, echocardiography enhances understanding of hemodynamic changes compared with right heart catheterization alone. IMPLICATIONS Acute hypoxemia in pigs is responsible for pulmonary vasoconstriction-induced pulmonary hypertension (which is restricted by the right ventricular failure), as well as a PaO2-dependent decrease in left ventricular afterload. These changes are better displayed by echocardiography than by right heart catheter.

Abstract
STUDY OBJECTIVES Contrast transthoracic echocardiography (TTE) is currently used to identify intrapulmonary shunt (IPS) in patients with end-stage liver disease. The aim of this study was to compare the use of contrast TTE and transesophageal echocardiography (TEE) in detecting IPS. DESIGN Thirty-seven consecutive outpatients with severe liver disease awaiting liver transplantation underwent contrast TEE and TTE. The IPS was assessed semiquantitatively in four grades with TEE and as positive or negative with TTE. SETTING ICU. INTERVENTIONS Patients underwent contrast TEE after pharyngeal anesthesia alone followed by contrast TTE. Contrast echocardiography was performed with a modified fluid gelatin solution. RESULTS Overall detection rate of an IPS was 51% with TEE and 32% with TTE (p < 0.001). Four patients had an IPS detected with TEE but not with TTE. Quality of imaging was poor in 22% with TTE and 0% with TEE (p < 0.001). A PaO2 < 80 mm Hg or a dyspnea was associated with an IPS in 56% and 50% of patients with TEE and in 33% and 25% with TTE, respectively. CONCLUSION Contrast-enhanced TEE is superior to TTE for detecting an IPS in patients with severe liver disease awaiting liver transplantation. The use of gelatin contrast solution allows an early detection of IPS. Because of the high sensitivity of TEE, all patients suspected of hepatopulmonary syndrome should undergo TEE in search of an IPS if TTE is normal.

Abstract
Percutaneous tracheostomy, a technique that can be performed at the bedside in the intensive care unit (ICU), is increasingly used for critically ill ventilator-dependent patients. Based on many clinical studies, this procedure appears to be simple, rapid and safer than conventional surgical tracheostomy. This technique produces a stoma tissue tract that fits snugly around the cannula, and this could explain the low incidence of infective complications. However, we report two cases of life-threatening cellulitis, a serious complication that has rarely been reported previously.

Abstract
PURPOSE To assess the effects of controlled ventilation with two I:E ratios on haemodynamic and left ventricular function in mechanically ventilated patients with moderate to severe respiratory disease, using fluctuation of the arterial pressure waveform and the changes in left ventricular areas obtained by transoesophageal echocardiography. METHODS Nine patients had their lungs ventilated using volume controlled ventilation with two I:E ratios 1:3 and 1:1). Respiratory rate was adjusted so that six cardiac beats occurred during a respiratory cycle. Systolic blood pressure variation (SBPV), left ventricular area variations measured by TEE and haemodynamic variables measured by PA catheter were compared. RESULTS When compared with I:E (1:3), I:E (1:1) decreased end diastolic area (EDA) throughout the respiratory cycle from 3% to 8% (P < 0.01) and increased SBPV from 6 +/- 1 to 11 +/- 1 mmHg (P < 0.01). In four patients, SBPV was > 12 mmHg with I:E 1:1. Conversely, SBPV was < 10 mmHg in all patients with I:E 1:3. With I:E (1:1), EDA decreased up to 7% during expiration (P < 0.01). The ejection fraction area remained stable for both ventilatory patterns and throughout the ventilatory cycle for a given I:E. The usual invasive haemodynamic variables were unchanged throughout the study, as was PaO2/FIO2. CONCLUSION In this setting, EDA and SBPV allow beat-to-beat evaluation of left ventricular preload during change of I:E ratio. Switch from I:E 1:3 to 1:1 may be used as a rapid, safe and reversible test to estimate intravascular volume status assessed by changes in SBPV or EDA.

Abstract
We report a case of fatal septic shock, with hyperlactatemia and blood cultures positive for Streptococcus pneumoniae, in a 70-year-old patient. On two occasions (5 days, and 2 days before the patient's death), the relationship between oxygen delivery (DO2) and consumption (VO2) was examined in conjunction with two presumed markers of tissue oxygenation: the lactate/pyruvate ratio (L/P), and the beta-hydroxybutyrate acetoacetate ratio (beta OHB/AcAc). Increasing DO2 by about 30% ("oxygen flux test") failed to increase VO2. The beta OHB/AcAc ratio remained within normal limits, thus suggesting uncompromised tissue oxygenation at the hepatic level. The L/P ratio remained persistently above normal limits, thus suggesting actual organ or regional hypoxia. This case shows that during an overwhelming septic shock, the "oxygen flux test" can be negative, despite the presence of hyperlactatemia and of an increased L/P ratio suggestive of impaired tissue oxygenation.

Abstract
The authors report a case of rupture of a mycotic aneurysm of the duodenal pancreatic arcade in a 68 year old man presenting with shock, abdominal pain and rigidity, complicating a case of infectious endocarditis. Emergency treatment consisted of selective embolisation with a coil. This treatment, proposed in view of the clinical condition of the patient and the anatomical particularity of the regional arterial vascularisation, may be a valuable alternative to classical surgery in this type of pathology.

Abstract
BACKGROUND The brain-dead donor supply has become one of the criteria limiting the performance of heart transplantation. Conventional screening criteria are too limiting and exclude suitable heart donors. Echocardiography is now widely available and is a reliable tool to assess left ventricular dysfunction in brain-dead donors. Yet few data are available on the degree of left ventricular dysfunction where a transplantation is possible. METHODS Fifty-five potential brain-dead heart donors (age 38 +/- 11 years) were prospectively evaluated by transesophageal echocardiography (TEE) before harvesting. Fractional area change (FAC) was used to assess left ventricular function in potential brain-dead donors. Transplanted hearts were evaluated on the fifth postoperative day. The transplantation was considered a success if the recipient was alive, not retransplanted, without an assistance device or an epinephrine infusion of more than 1 mg/h and showed an ejection fraction above 40%. RESULTS Of the 55 potential heart donors, 20 exhibited an FAC of less than 50%. Forty hearts were harvested, 36 of which were successfully transplanted. Nine patients had an FAC below 50% (group H2) and 27 had an FAC over 50% (group H1). Four patients died: 2 from hemorrhage (FAC > 50% in donors); 1 from right and one from left ventricular dysfunction (FAC < 50% in donors). The FAC increased significantly from 51 +/- 15% to 57 +/- 11% in 18 hearts that underwent TEE in donors and afterwards in recipients. Overall actuarial survival was 86.2% versus 64.6% at 1 and 2 years in group H1 and group H2, respectively (p = NS). CONCLUSIONS TEE is useful to assess left ventricular function in potential brain-dead donors. An FAC less than 50% is present in 36% of potential heart donors. Because left ventricular dysfunction is often reversible shortly after transplantation, an FAC below 50% may not necessarily preclude the use of hearts for transplantation.

Abstract
We conducted a randomized, double-blind, placebo-controlled study to assess the cardioprotective effects of trimetazidine (TMZ), an antiischemic drug, on left ventricular function using transesophageal echocardiography (TEE) after coronary artery bypass grafting (CABG). Forty patients undergoing elective CABG received either TMZ or a placebo (PCB). The primary measures of efficacy were serial measurements of fractional area change (FAC), percent of systolic wall thickening (SWT), and malonedialdehyde (MDA) production. The two groups were similar for the following variables: number of vessels revascularized (2.5 +/- 0.2 in the TMZ group and 2.8 +/- 0.1 in the PCB group), duration of aortic clamping (46 +/- 4 min in the TMZ group and 48 +/- 3 min in the PCB group), and bypass time (63 +/- 4 min in the TMZ group and 70 +/- 4 min in the PCB group). FAC increased by 12% in both groups 20 min after aortic unclamping (P < 0.05) and remained above the initial value at the sixth postoperative hour. SWT was 23.8% +/- 1.6%, 25.4% +/- 1.9%, then 21.6% +/- 1.5% in the TMZ group and 22.8% +/- 1.6%, 23.8% +/- 1.4%, then 22.3% +/- 1.6 % in the PCB group, after induction of anesthesia and 1 and 6 h after aortic unclamping (not significant). MDA increased by 24% in the PCB group and 25% in the TMZ group 20 min after aortic unclamping (P < 0.01). Lactate levels were lower in the TMZ group (P < 0.05) and patients from the TMZ group received less intravenous calcium before aortic clamping (P < 0.02) and less calcium channel entry blocking drugs in the early phase after aortic unclamping (P < 0.01) compared to the PCB group. We conclude that in patients with good preoperative ejection fraction undergoing CABG, TMZ as administered did not demonstrate clinically significant cardioprotective effects on left ventricular performance and lipid peroxidation compared to PCB.

Abstract
The pyogenic liver abscess is an uncommon but potentially lethal complication of colo-anal surgery. The authors report a case due to Streptococcus intermedius, a pathogen with a known ability to produce visceral abscesses, after haemorrhoidectomy. According to the French consensus conference, the patient had received a prophylactic preoperative antibiotic regimen consisting of metronidazole, active against S intermedius. Despite surgical therapy and adequate antibiotics, the patient died of hepatic failure.

Abstract
BACKGROUND Traumatic disruption of the aorta (TDA) is a life-threatening injury that requires rapid diagnosis and treatment. Emergency aortography, which is the current standard diagnostic imaging modality, is invasive, time-consuming, and difficult to perform in hemodynamically unstable patients with multiple trauma. We performed transesophageal echocardiography (TEE) in patients with suspected TDA to determine the diagnostic accuracy and impact on patient management of this alternative, portable imaging modality. METHODS AND RESULTS Thirty-two consecutive trauma patients (mean age, 40 +/- 16 years) with suspected TDA (violent deceleration accident and mediastinum > 8 cm on admission chest x-ray) prospectively underwent a TEE examination in the emergency room. Findings during TEE were compared with those encountered during aortography, surgery, or necropsy. Two subsets of traumatic aortic injuries with distinct echocardiographic signs were observed: (1) subadventitial TDA (n = 10) and (2) traumatic intimal tears (n = 3). Eighteen patients had normal TEE confirmed by aortography. One 2-mm medial tear was missed by TEE (necropsy). The sensitivity and specificity of TEE for the diagnosis of subadventitial TDA were 91% and 100%, respectively. Patients with subadventitial TDA were taken to surgery immediately, whereas patients with intimal aortic tears were treated conservatively. Eighteen patients (mean age, 57 +/- 15 years) with confirmed acute aortic dissection involving the aortic isthmus were also included to establish the echocardiographic differential diagnostic criteria between this entity and TDA. CONCLUSIONS TEE should be considered the first-line imaging modality for the evaluation of trauma patients with suspected injuries of the thoracic aorta because of its portability, safety, diagnostic accuracy, and potential impact on patient management.

Abstract
A 32-year-old pregnant woman with poor life and hygiene conditions presented with premature labour, fever and diarrhoea. After admission she gave birth to a stillborn child. The examination revealed a septicaemia with massive haemolysis and renal failure. Six blood cultures obtained on admission yielded Clostridium perfringens. The outcome was favourable after an adapted antibiomicrobial therapy. This case illustrates the potential severity of Clostridium perfringens foodborne toxi-infection which can lead to abortion and septicaemia with massive haemolysis.

Abstract
Fat embolism syndrome (FES) is a rare but serious complication occurring after long bone fractures. Presence of fat droplets in cells obtained by bronchoalveolar lavage has been proposed as a specific tool for FES diagnosis in trauma patients. We evaluated this technique over a 15-month period in 85 patients. Twenty-eight patients were excluded. The remaining 57 patients were divided into three groups: group 1, 26 patients without trauma as control; group 2, 22 patients with trauma but without evidence of FES; and group 3, nine patients with trauma and evidence of FES. Six of 26 patients in group 1 and nine of 22 patients in group 2 exhibited fat droplets in alveolar macrophages, whereas three of nine patients of group 3 had not. This study suggests that (1) presence of fat droplets in alveolar macrophages is not a reliable method for diagnosis of FES after long bone trauma, and (2) many conditions are associated with fat droplets in alveolar macrophages.

Abstract
A randomized study of 30 patients undergoing uncomplicated surgery under spinal anesthesia was conducted to assess the influence of colloids on the kinetics of plasma fibronectin and complement. Both are opsonins of the reticuloendothelial system; moreover fibronectin is concerned with host resistance against septic complications following trauma and surgery. The patients were assigned to receive either Ringer's lactate (Group 1), gelatin (Group 2) or dextran 40 (Group 3). Blood samples were withdrawn before colloids or Ringer's infusion and during the 4 postoperative days. There was a reduction in plasma fibronectin throughout the study in groups 1 and 3, but an increase in group 2 by 24 h. The adhesion of plasma fibronectin to gelatin was maximal 1 h after infusion (44%) and remained significant up to day 2 in group 2. There was no relationship in groups 1 and 3. C3 and C4 components of complement exhibited a low value in the early post-operative period, due to hemodilution. This study shows an in vivo fibronectin-gelatin interaction, and suggests that gelatin infusion inhibits the increased shift of plasma fibronectin at the site of tissue injury after surgery.

Abstract
A study was carried out to determine whether centrifugation and resistivity were reliable methods for measuring haematocrit of blood diluted with dextran or gelatin. The values obtained with the minicentrifuge Compur M 1100 (Bayer) (group 2) and with the Stat-Crit (Fumouze) (group 3) were compared with those obtained with the reference method (Coulter counter Model S + 2, Coultronics) (group 1). The study included 10 healthy subjects, aged 21 to 43 years. In each, sodium, potassium, chloride and protein concentrations were determined. Two further 10 ml blood samples were taken to be diluted with increasing amounts of either a fluid modified gelatin (Plasmion) or a dextran 40 (Piasmacair). The dilutions carried out were 0, 10, 20, 30, 40 and 50%. For each one, the haematocrit was measured using all three methods. The values obtained with undiluted blood were similar with the three methods. However, when blood was diluted with a dextran, haematocrit values were underestimated, whatever method was used, but by no more than 5% (difference not statistically significant). The result was the same with the centrifugation method for blood diluted with gelatin. On the other hand, values obtained with the resistivity technique for these samples were underestimated up to 15.5% (50% dilution; p less than 0.05). This was due to the negative electric charge of the gelatin, which lowered the haematocrit value in proportion to the concentration of gelatin. Although the technique is easier than centrifugation, measuring haematocrit with a resistivity method should be avoided in patients receiving a fluid modified gelatin.

Abstract
A nitrogen-sparing effect of epidural anesthesia has been clearly demonstrated in gynecological and lower abdominal surgery. To determine if epidural anesthesia also has a protein-sparing effect during major upper or mid-abdominal surgery, postoperative nitrogen balance and 3-methylhistidine urinary excretion (an index of skeletal muscle protein catabolism) were measured for 6 days in 28 patients who had undergone colon resection for cancer with general anesthesia (N2O-O2-1% enflurane) either supplemented with low dose fentanyl plus intermittent systemic pentazocine for postoperative pain (n = 13), or the same general anesthetic plus epidural injection of either etidocaine 1% intraoperatively and bupivacaine 0.25% postoperatively (n = 8) or meperidine (n = 7) for 48 hr after skin incision. The cumulative 6-day nitrogen balance and the cumulative 3-methylhistidine urinary excretion were significantly less after epidural injection of etidocaine intraoperatively and bupivacaine postoperatively than in the two other groups. There was a significant correlation between the daily urinary excretion of 3-methylhistidine and the daily nitrogen balance in the three groups. This study suggests that in colon surgery, epidural analgesia with local anesthetics in the postoperative period improves nitrogen balance and this effect takes place partly in the muscle.

Abstract
After out of hospital CPR thirty three resuscitated patients were studied for bacteremic complications. Thirteen patients (39%) had two or more positive blood cultures during the twelve hours following CPR. Source of superinfection was a central venous catheter in one case (staphylococcus). The twelve other bacteremic patients had fetid diarrhea a few hours after admission. The same organism were found in blood and faeces (streptococcus D, Escherichia coli, Pseudomonas aeruginosa, acinetobacter, enterobacter). Mesenteric ischemia caused by a low cardiac output may explain the diarrhea and the intestinal origin of the septicemia. All patients (12 cases) with diarrhoea and bacteremia died. Patients who recovered without neurologic sequelae (4 cases) had never been septic and never had diarrhea.

Abstract
The purpose of this study was to compare the effectiveness of a simple technique of active lung reexpansion through a fiberoptic bronchoscope, using a large volume syringe, with that of the conventional fiberoptic bronchoscope suction. Thirty consecutive patients with atelectasis were divided at random into two groups: with and without active inflation. The two groups were similar as regards age, sex-ratio, side and area involved in atelectasis. The group without inflation was less hypoxaemic than the other group (PaO2 202 and 140 mmHg respectively). Early and lasting improvement in chest X-ray and arterial blood gases occurred in both groups, but patients were significantly more improved during fiberoptic inflation. No pneumothorax or haemoptysis was observed during the procedure. These data prompt us to recommend active inflation instead of fiberoptic bronchoscopy suction alone for the emergency treatment of patients with severe hypoxaemic atelectasis.

Abstract
We investigated the clinical efficiency and safety of ofloxacin, a new fluoroquinolone, for the treatment of various documented bacterial infections in 26 patients (10 females, 16 males) aged 17 to 84 years. Ofloxacin monotherapy was given orally in a dose of 200 mg twice (25) or three times (1) a day. Antibiotic levels and serum bactericidal activity were measured using a microbiological method on the second and sixth days, before and 2 and 6 hours after a single dose. The infectious episode treated was enterocolitis in 7 cases (5 Shigella, 2 Salmonella), Salmonella septicemia in 9 (7 typhoid fevers and 2 Salmonella minor infections), chronic osteoarthritis in 3 (1 E. coli, 2 S. aureus + P. aeruginosa), a soft tissue infection in 3 (2 S. aureus, 1 E. coli), acute pleuropneumonia in 2 (2 Klebsiella pneumoniae), pyelonephritis with bacteremia in 1 (Klebsiella pneumoniae), and pneumococcal pneumonia with septicemia in 1. Mean duration of therapy was ten days for 23 patients (range 7 to 30 days). The three patients with osteoarthritis were treated for 35, 95 and 270 days respectively. 24 patients recovered free of sequelae or germ carriage. Treatment failed in 1 case of chronic osteitis (S. aureus + P. aeruginosa) and in 1 staphylococcal soft tissue infection. No adverse reactions were observed except a slight increase in transaminases in 3 patients. Peak and through serum ofloxacin levels were 3.70 micrograms/ml and 0.95 micrograms/ml respectively on the second day and 3.25 micrograms/ml and 0.80 microgram/ml respectively on the sixth day.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A case is reported of acute massive overdose with parathion in a 48 year old male farmer. Despite an adapted and early treatment, the clinical course was unusually prolonged. The need for repeat titration of plasma pseudocholinesterases, as the best indicator of overdose, is stressed. Recovery without after-effects coincided with the return to normal plasma levels of pseudocholinesterases.
