Abstract
18 critically ill patients, with multiple organ failure (MOF) (from shock either septic, n = 15, or cardiogenic, n = 3), oliguria and increase in BUN and creatinine were treated with pump driven, high flux continuous veno-venous hemofiltration (CVVH). Replacement fluids were administered in predilution mode. All patients were under respiratory support and vasoactive drugs, and received early nutritional support (N input: 0.2–0.3 g/kg/day). Mean duration of treatment was 9.2 days and mean ultrafiltrate production was 21.4 l/day; treatment resulted in a significant reduction of both urea nitrogen and creatinine blood levels (-20 and -40% of initial values respectively) in spite of a very severe catabolism. The total amount of urea nitrogen removed through CVVH ranged from 15 to 73 g/day (mean 33.5), the median value of urea nitrogen clearance was 12.8 ml/min with a median ultrafiltration coefficient of 0.8. The mean duration of hemofilters was 69 hours (38–108); the efficacy of filters remained stable throughout the entire lifespan and changes were made in case of sudden decrease of ultrafiltration (< ml/min). No major complication was observed in over than 4000 hours of treatment. Pump driven, high flux CVVH proved effective in the control of water electrolyte balance and metabolic homeosthasis in a group of critically ill, hemodynamically unstable, catabolic patients with MOF and acute renal failure. In no case we had to add intermittent hemodialysis or to use hemodiafiltration. The constant extracorporeal blood flow and the stable efficacy of hemofilters allowed an easy control of the overall effectiveness of this technique.

Abstract
We developed a protocol to procure lungs from uncontrolled donors after circulatory determination of death (NCT02061462). Subjects with cardiovascular collapse, treated on scene by a resuscitation team and transferred to the emergency room, are considered potential donors once declared dead. Exclusion criteria include unwitnessed collapse, no-flow period of >15 min and low flow >60 min. After death, lung preservation with recruitment maneuvers, continuous positive airway pressure, and protective mechanical ventilation is applied to the donor. After procurement, ex vivo lung perfusion (EVLP) is performed. From November 2014, 10 subjects were considered potential donors; one of these underwent the full process of procurement, EVLP, and transplantation. The donor was a 46-year-old male who died because of thoracic aortic dissection. Lungs were procured 4 h and 48 min after death, and deemed suitable for transplantation after EVLP. Lungs were then offered to a rapidly deteriorating recipient with cystic fibrosis (lung allocation score [LAS] 46) who consented to the transplant in this experimental setting. Six months after transplantation, the recipient is in good condition (forced expiratory volume in 1 s 85%) with no signs of rejection. This protocol allowed procurement of lungs from an uncontrolled donor after circulatory determination of death following an extended period of warm ischemia.

Abstract
BACKGROUND Refractory septic shock (RSS) requiring major vasopressor support is associated with high mortality, especially in Gram-negative infections. The study aim was to describe hemodynamics, organ failure, and clinical outcomes in high-dose vasopressor therapy (HDVT) RSS patients treated with Polymyxin B hemoperfusion (PMX-HP) as rescue therapy. METHODS We retrospectively analyzed 52 patients, unresponsive to conventional therapy, treated with two sessions of PMX-HP requiring HDVT (norepinephrine and/or epinephrine requirement (NEP+EP) ≥ 0.5 µg/kg/min), ≥ 2 organ failures, and suspected/confirmed Gram-negative infection from any source. RESULTS At baseline, mean arterial pressure (MAP) was 80 ± 13 mmHg and NEP + EP requirement was 1.11 ± 0.56 µg/kg/min. After two PMX-HP sessions, at 72 h, MAP significantly increased and NEP + EP requirement decreased respectively by 12% and 76%. Pulmonary and renal function also improved significantly. Thirty patients (58%) showed a ≥ 50% reduction in NEP + EP dose within only 24 h after the first PMX-HP session (early responders), and 22 did not or died from irreversible shock in the same time frame (early non-responders). The 30-day hospital mortality was 29%; it was 16% in early responders and 45% in early non-responders. On multivariate analysis, SAPS II score, vasopressin, and central venous pressure significantly affected 30-day hospital mortality. CONCLUSION This is the first study describing the use of PMX-HP as a rescue therapy in RSS patients with HDVT and MOF. Our results suggest a possible role for PMX-HP in improving hemodynamics, organ function, and mortality in RSS, with a 30-day survival of up to 70%.

Abstract
An epidemiologic evaluation of trauma-related deaths in trauma centers reveals that the majority of patients die within 6 hours from exsanguination, whereas secondary brain injuries predominate between 6 and 24 hours. Late deaths remain attributable to sepsis and pulmonary embolism,1-3 while early deaths are due in part to multiple bleeding injuries or to a set of complex and untreatable injuries, mainly of the liver and pelvis. Before trauma systems existed, these patients died at the scene of the trauma, whereas since the establishment of the trauma system, they die in emergency or operating rooms. Another subset of early deaths result from severe bleeding injuries, which could be prevented if recognized early. For instance, if a 70 kg adult had a blood volume of 70 mL/kg (5 L), hypotension (systolic blood pressure [SBP]<90 mmHg) would usually occur after a one third-loss of blood volume, and death would follow with a 50% loss. A patient bleeding at a rate of 25 mL/min will become hypotensive within one hour and die within two hours, while a patient bleeding at a rate of 100 mL/min will be hypotensive within 15 minutes and die within 30 minutes. These considerations indicate a narrow window of opportunity for targeting fluid resuscitation. Moreover, increases in blood pressure before surgical hemostasis have been shown to disrupt clotting and increase bleeding, a fact that has been confirmed by a number of animal and human studies on uncontrolled hemorrhage. Furthermore, oxygen must be delivered to vital organs (brain, heart) to prevent death during hemorrhage. In summary, several constraints account for the differences in fluid use, timing of infusions, and determinations of whether to administer fluids at all.

Abstract
BACKGROUND The aim of this study was to prove the existence of a direct relationship between the comprehensive strategy of trauma management and an enhancement in outcome. Tests were carried out on the impact of the Niguarda Trauma Team System on mortality rates due to severe trauma. METHODS The epidemiological data was retrospectively reviewed along with, the severity scores: Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), Revised Trauma Score (RTS), Probability of survival (Ps) and the outcome of severe trauma admitted to Niguarda hospital between October 2002 and September 2005. All data were collected from the Trauma Registry of the Niguarda Hospital. Two subsequent periods of 20 and 16 months were compared. RESULTS Nine hundred forty-two severe traumas (94.05% blunt trauma) were recorded with an overtriage rate of 36.09%. Most patients were admitted for bone and muscular injuries (52.22%). Excluding the patients who were overtriaged, there were 129 patients who died. Comparing the two periods, the Authors observed a significant reduction in mortality from 22.56% to 19.75%, mainly related to a decrease in early mortality due to hemodynamic instability. Central nervous system injury was the main cause of death (65%). Average hospital stay significantly decreased from 17.01+/-12.07 days to 14.97+/-10.34 days. CONCLUSION Introducing a comprehensive strategy of severe trauma management, the Niguarda Trauma Team System had a significant impact on mortality rates and hospital stay.

Abstract
AIM Massive haemorrhage after trauma is a big challenge for care-givers, being a leading cause of early in-hospital mortality. Surgical bleeding may be easily controlled with several techniques. Otherwise, consumptive coagulopathy is often extremely difficult to stop. An adjunctive strategy to treat traumatic coagulopathic bleeding is recombinant activated factor VII (rFVIIa) (NovoSeven, Novo Nordisk A/S, Bagsvaerd, Denmark). METHODS All major trauma victims haemodinamically unstable (systolic blood pressure < 90 mmHg or > 90 mmHg with massive infusions or vasopressors) admitted to the Emergency Department of the Niguarda Ca' Granda Hospital in Milan from October 2002 to September 2005 were reviewed. Mechanical bleeding was controlled with interventional techniques when indicated. Blood derivatives were administrated to maintain haemoglobin> 7 g/dL, INR < 1.5, fibrinogen > 1 and platelet count > 50 x 109. Off-label administration of rFVIIa was performed in the last year in any coagulopathic salvageable patient when all other strategies failed to control bleeding. RESULTS Major trauma were 942, mean age 32.49+/-18.44 years, 94% blunt trauma, 25.13% haemodynamically unstable. Deaths occurred in 17.02% of cases before any procedure. Emergency invasive treatments were performed in 72.34% of cases. Infusions restored haemodynamic stability in 10.63% of patients. In average 9.4+/-4.1 units of red blood cells were transfused in unstable patients. rFVIIa (dosing 60-100 mg/kg) was administrated in 12 patients. Mortality occurred in 33.33% of cases. The principal cause of death was brain injury. A femoral artery thrombosis was observed in a mangled leg. No other adverse effects due to rFVIIa were documented. CONCLUSIONS Off-label administration of rFVIIa was able to reverse life-threatening bleeding not manageable with standard strategies in our series of major trauma patients without systemic adverse effects.

Abstract
OBJECTIVE In a Trauma System, Trauma Registry allows the assessment of epidemiology and quality of patient care. MATERIALS AND METHODS Data about trauma patients admitted to Ospedale Niguarda Emergency Department from October 1, 2002 to June 30, 2003 with ICD9CM code 800-939.9 and 950-959.9 were prospectively recorded. Injury severity score (ISS) and revised trauma score (RTS) were calculated and probability of survival (Ps) was derived. RESULTS During the study period 1811 trauma patients were admitted, and 271 (14.96%) were consistent with triage criteria of severity. Among these, survivors were 220 (81.18%) and blunt trauma 95.94%. Injuries of the central nervous system with (11.76%) or without (50.98%) hemodynamic instability or hemodynamic instability alone (31.37%), were the principal causes of death. An ISS greater than 15 was observed in 61.25% with an overtriage of 38.75%. Seventy seven patients accepted without triage criteria of severity died or were admitted to intensive care unit with an undertriage of 5%. Ps among victims was 22.35 +/- 27.19 and possible preventable deaths were 6 (11.76%). No frankly preventable death was recorded. DISCUSSION Standard pre-hospital triage criteria are associated with significant over and undertriage. Data collection using large population-based data base increases epidemiologic value of trauma registry. Analysis of Ps identifies cases who need clinical discussion to assess adequacy of treatment. CONCLUSIONS Prospective data collection in a trauma registry may provide all informations useful to improve quality of trauma patient care.

Abstract
BACKGROUND In order to contribute to the dissemination of an organ and tissue donation culture, the authors report the results of a retrospective investigation into the donation of corneas for transplantation relative to the period from January 1997 to December 2001 at a leading hospital in the Milan area. METHODS All cases of intra-hospital death (n=2137) were considered. The adoption of a selection protocol for potential donors, in accordance with the indications of the North Italy Transplant program, and constant monitoring on the part of the local coordinator, led to the collection of 348 corneal flaps using the procedure whereby all deaths have to be notified to the Health Department. RESULTS Over this period, the donors/deaths ratio increased from 2.1 to 17.6%, while the collection index (real donors/potential donors including those wrongly excluded) increased from 40.8% in 1999-2000 to 67.8% in 2001. Most involved in the donor selection activity were the intensive care centres with an increase for Resuscitation of 12.7% and for First Aid of 33%, to a lesser extent non-intensive centres (increase of 11.2%). The causes of exclusion from cornea collection in the last three-year period were clinical contraindications in 51.2% of cases (sepsis, blood transfusions, diseases of the central nervous system of unknown aetiology), failure to activate the procedures in 17.4% of cases, opposition in 17%, unsuitability of the corneal tissues in 11.3%, inadequate age in 3%. CONCLUSIONS The results obtained indicate good prospects for technical implementation and for the development of a donation culture in respect of other organs and tissues.

Abstract
BACKGROUND To evaluate the effects of a protocol designed to optimize the use of preoperative chest X-rays (CXRs) in the evaluation of patients undergoing anesthesia for elective surgery. DESIGN Observational prospective study. SETTING General 350 bedded hospital, with main surgical branches. METHODS a) PROTOCOL routine CXRs can be avoided in patients aged less than 60 years, nonsmokers, without acute-chronic respiratory, cardiovascular symptoms, free from neoplastic diseases, not candidates to major vascular, abdominal or thoracic surgery, not treated with immunosuppressive therapy, nor immigrants from areas of endemic TB. b) All out patient subjects admitted to anesthesiology service for evaluation prior to elective surgery. RESULTS Out of 5198 patients, 3795 were enrolled in the protocol; in 152 cases, preoperative CXRs were performed, 3456 patients (57.2% ASA 1; 42% ASA 2; 0.8% ASA 3) underwent surgery without CXRs. Thirty-four percent of patients had general anesthesia, 54.5% regional anesthesia, 20.6% regional-peripheral anesthesia with/without MAC. No critical events nor major complications were observed in the perioperative period in these subjects. Preoperative CXRs (performed in 152 cases) yelded useful informations with effect on the clinical management in 20 instances. CONCLUSIONS In a context of adequate preoperative anesthesiologic evaluation, this protocol proved to be effective in reducing the number of routine preoperative CXRs in patients undergoing elective surgery. This resulted in a substantial reduction of radiation exposure both to the subject and to the general population, and costs saving, without evident negative side-effects.

Abstract
The anaesthetic technique chosen for a laparohysterectomy in a woman affected by Apert's acrocephalosyndactilia is described. Difficulties in performing tracheal intubation were overcome by mean of loco-regional anesthesia (LRA). In order to minimize the anaesthetic risk, a standardised preoperative evaluation and assessment integrating the usual investigations and the possibility of employing intubation techniques as alternative to direct laryngoscopy are suggested.

Abstract
OBJECTIVE To assess and to follow along the time-span of ICU stay the process of resources allocation and utilization. DESIGN Prospective study. PATIENTS A cohort of 778 patients consecutively admitted to 7 multipurpose general ICU in the Milano area were enrolled in a survey of the daily performed interventions/procedures. MEASUREMENTS AND MAIN RESULTS The majority of diagnostic procedure/interventions were performed during the first two days. The number and quality of interventions were transferred into points obtaining a score system in non-monetary units. The resource allocation process shows a regular trend in the sub-intensive patients who were only monitorized. On the contrary the 258 patients who were intensively treated and survived show a phase of high resource-consumption (about 30 daily points: roughly twice the score of monitorized patients) then followed by a post-intensive phase with a resource consumption resulting in a daily score absolutely equal to the sub-intensive patients. The intensive patients who die show a significantly higher score than survived patients. Both daily and cumulative scores do not show differences among different type of patients. CONCLUSION The evaluation of the process of resources allocation, even if in non-monetary units enables the knowledge of the trend of ICU costs and allows the elaboration of the appropriate budget mechanism.

Abstract
This report describes a computer based program of patient clinical data collection: the ARCHIDIA system. The project relies on descriptive analysis of clinical events according to well defined methodological criteria. This allows the formulation of a concise diagnosis which is, at the same time, exhaustive of all essential information. Two are the basis principles of this methodology: To define, as accurately as possible, the logical steps necessary to elaborate the diagnosis, that is construed by a sequence of codes. To define all the conditions that must be followed so to use any code in a controlled and independent way. These criteria were derived from literature. The major claim of the system is likely to be the introduction of a "common language" between different ICUs. Uniformed diagnostic and clinical criteria are the main source of large data collection for descriptive, analytic and prospective studies. After a one year pilot study performed by 4 ICUs, ARCHIDIA was used, in 1991, by 20 centers from the area of Milan, Pavia, Como, Varese (70% of total) and 4148 patient data were collected. A descriptive analysis will be reported in the following paper.

Abstract
OBJECTIVE To describe a population of patients admitted in ICU in an homogeneous urban area by means of a computed system. EXPERIMENTAL DESIGN Observational study. SETTING 20 general intensive care units of general and university hospitals. PATIENTS Patients admitted in ICU from 1-1-1991 to 31-12-1991. 3 centers collected patients only for 6 months, starting on 1-6-1991. MEASUREMENTS For each patient demographic data, hospitalization data, outcome, diagnosis and diagnostic procedures used during hospitalization according to defined criteria previously described, were collected. Data have been collected on PC using dedicated software. RESULTS All centers concluded data collection, none abandoned the study. General characteristics of 4148 valuable patients were reported. Age was 52.9 years, SAPS 12.4 and mortality 21.7%. The patients spent 8.7 days in ICU and, when transferred to a general ward, the following hospitalization was 21.5 days. CONCLUSIONS Data collection demonstrated the project feasibility. It realizes a continue up to date system inside each unit and allows the use of a "common language" and homogeneous methodology between centers.

Abstract
OBJECTIVE To evaluate efficacy and tolerability of enoximone, a phosphodiesterase inhibitor, in the treatment of cardiogenic shock. DESIGN A prospective non randomized, non comparative study. SETTING A general intensive care unit of a university hospital. PATIENTS Six patients with cardiogenic shock (cardiac index < 2.5 l/min/m2, PWP > 15 mmHg) unsuccessfully treated with catecholamines. INTERVENTIONS Enoximone was administered (0.5-1 mg/kg)by iv bolus according to clinical response (CI > or = 2.5 l/min/m2), then was continued by iv infusion (5-16 micrograms/kg/min). Dopamine infusion at low doses (3 micrograms/kg/min) was maintained during the study. In all patients a pulmonary artery catheter was inserted before the study began. MEASUREMENTS AND MAIN RESULTS Direct and measured (using standard formula) haemodynamic parameters were registered. Basal data (before treatment) were compared with values after 30 minutes (bolus) and 8 hours (maintenance). CI (+57%) and O2 delivery (+74.7%) were significantly increased after 30 minutes and 8 hours, O2 extraction ratio normalized whereas heart rate and systemic blood pressure were unchanged. CONCLUSIONS Enoximone proved to be safe and effective in the treatment of cardiogenic shock. Its pharmacological effects combines inotropic and vasodilatant action without any change of heart rate thus avoiding an increase of O2 consumption in the jeopardized myocardium. Further studies will define better its routine use in critically ill patients with acute heart failure.

Abstract
OBJECTIVE To describe the use of an automatic fluid control system, Equaline, during high flux continuous hemofiltration. DESIGN Prospective descriptive study. SETTING General intensive care unit in a general hospital. PATIENTS 15 consecutive patients suffering from septic shock, hypercatabolic with acute renal failure. INTERVENTION Pump driven continuous veno-venous hemofiltration (PDCVVH) with high flux was performed. All pts were intubated, under mechanical ventilation and treated with vasoactive agents for hemodynamic instability. Fluid balance was achieved with an automatic fluid control system, Equaline, on daily basis according to clinical needs. MEASURES Length of treatment, daily amount of ultrafiltrate and urea removal, urea and creatinine blood level before and after the treatment were registered. RESULTS Age was 59.1 years, SAPS 17.2. Patients were treated for an average period of 9 days obtaining a daily ultrafiltrate production of 21.4 L. In all pts, though the high catabolism (daily nitrogen production > 30 g), there was a significant decrease of urea and creatinine concentration. CONCLUSION Equaline system was able to maintain intravascular volume in the face of high ultrafiltration rate avoiding clinically important discrepancies between ultrafiltrate formation and fluid replacement. We conclude that PDCVVH management is greatly improved with use of such servo-controlled feedback system.

Abstract
18 critically ill patients, with multiple organ failure (MOF) (from shock either septic, n = 15, or cardiogenic, n = 3), oliguria and increase in BUN and creatinine were treated with pump driven, high flux continuous veno-venous hemofiltration (CVVH). Replacement fluids were administered in predilution mode. All patients were under respiratory support and vasoactive drugs, and received early nutritional support (N input: 0.2-0.3 g/kg/day). Mean duration of treatment was 9.2 days and mean ultrafiltrate production was 21.4 l/day; treatment resulted in a significant reduction of both urea nitrogen and creatinine blood levels (-20 and -40% of initial values respectively) in spite of a very severe catabolism. The total amount of urea nitrogen removed through CVVH ranged from 15 to 73 g/day (mean 33.5), the median value of urea nitrogen clearance was 12.8 ml/min with a median ultrafiltration coefficient of 0.8. The mean duration of hemofilters was 69 hours (38-108); the efficacy of filters remained stable throughout the entire lifespan and changes were made in case of sudden decrease of ultrafiltration (< ml/min). No major complication was observed in over than 4000 hours of treatment. Pump driven, high flux CVVH proved effective in the control of water electrolyte balance and metabolic homeostasis in a group of critically ill, hemodynamically unstable, catabolic patients with MOF and acute renal failure. In no case we had to add intermittent hemodialysis or to use hemodiafiltration. The constant extracorporeal blood flow and the stable efficacy of hemofilters allowed an easy control of the overall effectiveness of this technique.

Abstract
Complement activation is necessary for an adequate immune and inflammatory response to infections. Activation releases anaphylatoxins that cause vasodilation, increase vascular permeability, and trigger release of polymorphonuclear neutrophil leukocyte (PMN) lysosomal enzyme and oxygen radicals. Under normal circumstances, an orderly progression of such events has a beneficial antimicrobial effect. The same mechanism, however, when uncontrolled, may damage host tissues. To provide information about the clinical importance of such events in sepsis, different complement parameters (C3, C4, and the desarginated forms of C3a [C3a(des)-Arg] and C5a [C5a(des)-Arg]), PMN elastase, and malondialdehyde (a by-product of membrane peroxidation by oxygen radicals) were measured daily in 26 septic patients and correlated with two objectively assessed and previously validated severity scores (acute physiology and chronic health evaluation [APACHE II] and Sepsis Severity Score [SSS]). Nonsurvivors (n = 12) had significantly greater and longer lasting complement activation than that in survivors, as reflected by higher levels of catabolic peptides (C3a(des)-Arg) and lower levels of native proteins (C3 and C4). C3a(des)-Arg, C3, C4, and the C3a(des)-Arg-C3 ratio were correlated with Sepsis Severity Scores. Polymorphonuclear neutrophil leukocyte elastase levels were higher in nonsurvivors and were correlated with C3a(des)-Arg and the C3a(des)-Arg-C3 ratio. Malondialdehyde levels were significantly higher in all patients than in controls, without, however, any relationship to severity of disease or clinical outcome. Since the higher and more persistent the complement activation and polymorphonuclear neutrophil leukocyte stimulation, the worse the patient's prognosis, we conclude that these mechanisms may be important in the clinical development of sepsis.

Abstract
Despite consistent improvement in its treatment, amatoxin poisoning still extolls an elevated overall mortality, ranging between 10 and 15%, which approaches 100% when severe (grade 3-4 encephalopathy) hepatic failure supervened. Therefore, the proper treatment of intoxication by amatoxin containing mushrooms, and particularly of its complications, remains a challenge in emergency medicine. Klein and coworkers reviewed the role of liver transplantation in amatoxin poisoning as a useful therapeutic tool for patients with severe impairment of liver function. Their indication for intervention is the presence of any of the following signs: grade 2 encephalopathy or higher; prothrombin time twice than normal, despite fresh frozen plasma infusion; hypoglycemia requiring hypertonic glucose infusion; hyperbilirubinemia (greater than 25 mg/dl). During the past autumn two patients with fulminant hepatic failure due to amatoxin poisoning were referred to our institutions as candidates for liver transplantation, since both satisfied Klein's criteria. However, due to shortage of organ donors it was impossible to transplant them over the following days. Despite they did not receive liver transplantation, both patients wakened from coma, their liver function improved, and they recovered from terminal amatoxin poisoning. After one year, both patients are long-term survivors, in good health and without any sequelae either in brain or liver function.

Abstract
The study was performed to investigate efficacy and tolerability of the association propofol-ketamine as alternative to propofol-fentanyl. Forty female, classified ASA I-II, aged 18-50 years and scheduled for short gynecologic procedures under general anesthesia were included in a comparative, randomized, single blind study. Patients were divided in two groups; in group K anesthesia was induced with propofol 1.5 mg/kg and ketamine 1 mg/kg i.v. In group F anesthesia was induced with propofol 2.5 mg/kg and fentanyl 1.5 micrograms/kg. Arterial blood pressure (BP), heart rate (HR), respiratory rate (RR) and arterial O2 saturation (SATO2) were measured. Though preliminary, our data suggest that the association propofol-ketamine reach an adequate level of anesthesia with few and negligible effects on cardiorespiratory system, thus allowing a better operability and safety. The incidence of post operative psychotic disturbances seems to be low and moderate. We can't draw any definitive conclusion, but we think that other studies should be performed to clarify the possible role of ketamine in propofol anesthesia.

Abstract
Pulmonary microvascular occlusive disease has been investigated using balloon occlusive pulmonary angiography in 31 patients with severe adult respiratory distress syndrome (ARDS) of different origins (14 patients with pneumonia, nine with multiple injury, eight with sepsis). Multiple pulmonary artery filling defects (PAFD) were detected in 13 (42%) patients, with a seven (78%) in nine incidence among those with posttraumatic ARDS. The presence of PAFD did not correlate with the severity of the respiratory failure, with the pulmonary hemodynamic alterations (pulmonary hypertension and increased vascular resistance), or with the final outcome (mortality rate was 54% among patients with PAFD and 61% among those with normal angiograms). These findings suggest that widespread pulmonary microthrombosis is a common event in patients with polytrauma and respiratory failure, with an important pathophysiologic role in the onset of posttraumatic ARDS.

Abstract
Ten patients with acute respiratory failure (ARF), (4 pneumonia, 4 sepsis, 2 polytrauma), underwent computerized tomography (CT) of the lungs, (apex, hilum, base), at 5, 10, 15 cm H2O positive end expiratory pressure (PEEP). The ARF lungs, on CT scan, appeared as a patchwork of normal and dense areas with generally well defined boundaries. Most of the densities were found in the dependent regions. The areas of density were correlated with PaO2 (r = 0.51). The PEEP increase resulted in a significant expansion of total cross-sectional lung surface area. The dense areas decreased significantly at the hilum and base when increasing PEEP while the changes at the apex were not significant. The changes of density with PEEP were highly correlated with the changes in oxygenation (r = 0.91). In the individual patient, however, the modifications of gas exchange can not be entirely predicted from morphological changes, possibly due to a diversion of pulmonary blood flow.

Abstract
Poisoning by cytotoxic mushrooms (Amanita phalloides and related species) is associated with severe morbidity and a high mortality rate. Due to the difficulty of performing controlled studies and to the poor knowledge of the pharmacodynamics of toxins in human poisoning, there is considerable debate about appropriate treatment, particularly the feasibility and the efficacy of detoxification. Because circulating amatoxins can be detected in the serum of poisoned patients as long as 30 h after ingestion, a detoxification treatment should ideally increase the rate of toxin elimination in order to minimize the toxic exposure of highly susceptible cells, such as hepatocytes. We found forced diuresis to be the most effective procedure for toxin removal. Other techniques, such as plasmapheresis and peritoneal dialysis, proved much less useful for this purpose. The administration of cathartics, adsorbent agents, and gastroduodenal lavage, are indicated for preventing further absorption of toxins from the gut. An important part of therapy is early and vigorous volume replacement, to correct the severe hypovolemia which results from massive fluid loss during the cholera-like phase of intoxication. Use of this therapeutic approach in 53 patients with amatoxin poisoning resulted in a high survival rate and a low incidence of severe liver injury.

Abstract
Factors influencing nitrogen balance during total parenteral nutrition have been investigated in 34 critically ill injured patients studied during the first 6 days after trauma. Basal nitrogen balance was severely negative (-0.26 +/- 0.12 (SD) g X kg-1), but improved consistently during treatment. Nitrogen intake proved to be the major determinant of a positive, or less negative, nitrogen balance, only secondarily followed by total energy intake corrected to predicted basal energy expenditure, according to multiple regression analysis. The amount of non-protein calories and the non-protein calorie to nitrogen ratio appeared to have little significance on nitrogen balance, when corrected for the two former variables.

Abstract
The metabolic effects of TPN were studied in a selected group of trauma patients. Nineteen patients were randomly divided into two groups: the first was treated with glucose and insulin, the second with glucose, insulin and amino acids. Each patient in both groups received TPN isocaloric with respect to daily energy output and the treatment lasted five days. Each group was further divided into two subsets (severe or moderate catabolism) according to fasting energy output with respect to the expected energy expenditure. During the acute flow phase, both in moderate as well as in severe catabolism, glucose and insulin were effective for protein sparing; the maximum protein sparing effect was reached when giving a caloric intake equal to 130% of daily energy output. Glucose, insulin and amino acids were effective in replacement of nitrogen losses. In moderately catabolic patients nitrogen balance was significantly better than in severely catabolic patients. This study shows that early and short-term TPN is effective in controlling the flow phase of trauma. Glucose and insulin appear to be the determinants of the protein sparing effect when given in amounts equal to those needed; amino acids provided protein replacement when given in amounts equal to about 20% of energy output. Energy supply higher than 120-130% of daily energy output does not increase protein sparing and protein replacement, the only effect being a further increase in metabolism, which is possibly dangerous in critically ill patients.

Abstract
In a patient with thrombotic thrombocytopenic purpura (TTP) severe neurological complications leading to coma were repeatedly reversed by treatment with urokinase. Although the therapeutic modalities for TTP still appear to be a matter of debate, thrombolytic treatment could be considered in TTP patients with severe organ involvement before the corresponding function is completely compromised.
