Hemofiltration does not influence early S-100B serum levels in septic shock patients receiving stress doses of hydrocortisone or placebo.
BACKGROUND: The prognosis in patients with hyperdynamic septic shock correlates with the presence and the severity of septic encephalopathy. However, the neurological evaluation is considerably influenced by the use of analgesia sedation during mechanical ventilation. An early concentration peak of the neuroprotein S-100B in serum reflects both cellular damage at an increased permeability of the blood-brain-barrier and a delayed renal elimination. Thus, the objective of this study was to analyze the effect of continuous veno-venous hemofiltration (CVVH) on early S-100B serum levels in septic shock patients, who were treated with either stress doses of hydrocortisone or placebo. METHODS: Twenty-four consecutive patients, who met the ACCP / SCCM criteria for septic shock, were enrolled in this prospective, randomised, double-blind, single-center trial. The severity of illness at recruitment was graded using the APACHE II and SAPS II scoring systems; the MODS was described by the SOFA score. All patients were prospectively randomised to receive either stress doses of hydrocortisone or placebo. Hydrocortisone was started in 12 patients with a loading dose of 100 mg and followed by a continuous infusion of 0.18 mg/kg/h for 6 days. RESULTS: Median S-100B serum levels of the hydrocortisone group decreased from 0.32 ng/ml (0.19-3.60) at study entry to 0.07 ng/ml (0.04 - 0.32) 6 days later without significant differences compared to the placebo group. Patients undergoing CVVH showed significantly higher S-100B serum values compared to patients without CVVH (p<0.001). However, initial median S-100B serum levels of the CVVH group even increased from 0.92 ng/ml (0.16 - 4.63) to 2.33 ng/ml (0.59 - 2.44) 30 hours after study entry, reaching data ranges already known in patients with out-of-hospital cardiac arrest or severe traumatic brain injury. CONCLUSION: Early S-100B serum levels in septic shock patients receiving either stress doses of hydrocortisone or placebo were not influenced by CVVH. For the first time, we observed a similar extent of S-100B serum increase in CVVH patients, who had significantly higher S-100B serum values compared to those without CVVH, as reported for out-of-hospital cardiac arrest or severe traumatic brain injury. Hypercortisolemia induced by the infusion of stress doses of hydrocortisone did not significantly reduce early S-100B serum concentrations with time.

[PTSD in somatic disease].
This review describes the incidence of posttraumatic stress disorder (PTSD) in physically ill patients. At the beginning, research in the field of PTSD was primarily focused on war veterans and victims of bodily assault or rape. Starting in the early 90 s, PTSD after civilian traumas such as motor vehicle accidents was diagnosed increasingly more often. Recent publications showed that PTSD can also follow serious somatic diseases. Hence, awareness during anaesthesia, prolonged ICU treatment (ARDS, septic shock), burns, successful resuscitation after cardiac arrest, coronary artery bypass surgery, organ transplantation and cancer were all linked to the development of PTSD. Prevalence of PTSD in these medical conditions lies around 5 - 10 %, and it is therefore considered an important comorbidity. Unfortunately, the diagnosis and treatment of PTSD are not well enough established yet and thus do receive too little attention in the treatment regime of somatic illness. Generally, PTSD can occur with every life-threatening disease, but possibly also with less severe diseases if the patient experiences intense fear. PTSD symptoms, especially intrusive recollections, avoidance and hyper-arousal can impair the patients' quality of life more than the primary disease. This seems to be also true for sub-syndromal PTSD. To adequately diagnose and treat patients at risk of developing PTSD, close collaboration between physicians of all subspecialties and psychiatrists will be necessary.

Quality of life in patients with multiple injuries--basic issues, assessment, and recommendations.
BACKGROUND: While the primary goal of trauma care continues to be the preservation of life, interest has begun to focus on disability and quality of life of those who survive. Numerous instruments have been developed to measure personal well-being, impairment, or subjective life-satisfaction. But there is no consensus regarding which instruments are most appropriate to use in multiply injured patients, and comparison of results are difficult. OBJECTIVE: The objective of this multinational conference was to arrive at a consensus regarding the measurement of quality of life in survivors of multiple trauma. Specifically we sought to identify the best time intervals for measurement and a minimum set of instruments. METHOD: The group reviewed instruments currently in use for quality of life measurement in multiply injured patients. A structured discussion covered the following topics: definition of the population, the concept of quality of life, the importance of different domains of quality of life at different time points, the type of measures and their validity, consistency, and practicability, the mode of administration, subject burden, and availability of population norms. RESULTS: The group suggested three time points, after 3, 12 and 24 months, for the assessment of quality of life after multiple injury. The Glasgow Outcome Scale (GOS) was suggested as an overall global outcome measure including death and vegetative state. The EuroQol was proposed to permit economic analysis, and the SF-36 as a validated global quality of life measure. CONCLUSION: While most selected measures are psychometrically sound, many have had limited use in the setting of multiple injuries. Researchers and clinicians may use these suggestions as a source of information when developing a measurement strategy.

The effect of stress doses of hydrocortisone during septic shock on posttraumatic stress disorder in survivors.
BACKGROUND: Exposure to intense physical and psychological stress during septic shock can result in posttraumatic stress disorder in survivors. Patients with chronic posttraumatic stress disorder often show sustained reductions in serum cortisol concentration. This investigation examines whether increasing serum cortisol levels with hydrocortisone treatment during septic shock reduces the incidence of posttraumatic stress disorder in survivors. METHODS: Patients (n = 20) were recruited from a prospective, randomized double-blind study on the hemodynamic effects of hydrocortisone during septic shock. Eleven patients had received placebo and nine stress doses of hydrocortisone. Posttraumatic stress disorder was diagnosed 31 months (median) after intensive care unit discharge using SCID-IV (DSM-IV-criteria). Furthermore, the number of categories of traumatic memory from ICU treatment was determined in both groups at that time. RESULTS: Only one of nine patients from the hydrocortisone group developed posttraumatic stress disorder, compared with seven of 11 patients in the placebo group (p =.02). There was no significant difference with regard to the number of categories of traumatic memory between the hydrocortisone and placebo groups. CONCLUSIONS: The administration of hydrocortisone during septic shock in a dosage similar to the endogenous maximal production rate was associated with a lower incidence of posttraumatic stress disorder in long-term survivors, which seems to be independent of the number of categories of traumatic memory.

[Exertion-related heat stroke. Lethal multiorgan failure from accidental hyperthermia in a 23 year old athlete].
We report the case of a 23-year-old rower who suffered from an exertional heatstroke while trying to lose 2 kg in weight by jogging before a competition. The development of this illness was favoured by clothes that were inappropriate for the environmental conditions and which the sportsman wore intentionally to enhance sweating. The maximum core temperature was over 43 degrees C. As a consequence the comatose patient developed a fulminant multi-organ failure with the liver ceasing its function, renal failure, massive rhabdomyolysis, and disseminated intravascular coagulation. In addition, he suffered from pericardial effusion and acute pulmonary failure (ARDS). In spite of maximum intensive care with an extensive substitution of blood products, continuous hemodiafiltration, and inhalative administration of nitrous oxide the young sportsman died 48 h after his admission to the intensive care unit. This tragic course demonstrates the danger of the widespread habit of losing weight by vigorously exercising with inappropriate clothes. In this article, potential risk factors, symptomatology, therapy, and methods of preventing an exertional heatstroke are shown and discussed.

[Acute kidney failure. Physiopathology--clinical diagnosis--therapy].
Acute renal failure (ARF) is characterized by an acute decrease in glomerular filtration rate (GFR). ARF complicates 4% to 23% of intensive care unit admissions, and is associated with a mortality of approximately 50% among critically ill patients. In the intensive care setting the term ARF is usually applied to acute tubular necrosis (ATN), a form of intrinsic ARF caused by ischemia or nephrotoxins. Pathophysiological mechanisms involved in the decline in GFR include tubular obstruction caused by detachment of tubular epithelial cells from the basement membrane and back-leak of glomerular filtrate as a consequence of disruption of the epithelial cell layer. Vascular mechanisms involved in the pathophysiology of ATN are vasoconstriction due to an imbalance between vasoconstrictive and vasodilatory mediators and vascular obstruction caused by cell aggregation. Currently, there is no real time method to monitor renal function comparable to the real time monitoring of blood pressure or arterial oxygen saturation. Urinary output does not reflect glomerular filtration which may be critically reduced despite normal urine volumes and creatinine clearance still provides the clinically most applicable estimate of GFR. Tubular function can be assessed using the fractional excretion of sodium or the ratio of urinary and serum osmolality; both parameters can be obtained from spot samples of urine and serum and no urinary sampling period is necessary. However, both parameters are strongly affected by the administration of loop diuretics and high fluid and sodium inputs which are common in the intensive care unit. We determined the day to day variability of creatinine clearance, fractional excretion of sodium and the urinary to serum osmolality ratio in critically ill patients without renal dysfunction (i.e. creatinine clearance in the normal range) and found differences of 16% for creatinine clearance, 79% for fractional excretion of sodium and 22% for urinary to serum osmolality ratio. Treatment of ARF is mainly supportive and there is no clinically accepted therapy that attenuates the course of ATN. Treatment of the underlying disease and renal replacement therapy are the main options for the treatment of patients with ARF. In critically ill patients continuous venovenous hemo(dia)filtration is the first choice because it provides more hemodynamic and metabolic stability than intermittent therapy. Acute life-threatening hyperkalemia is an indication for intermittent hemodialysis because of the higher efficacy of dialysis in the clearance of low molecular weight substances.

Pulmonary function and health-related quality of life in a sample of long-term survivors of the acute respiratory distress syndrome.
OBJECTIVE: We performed a follow-up cohort analysis in order to delineate the correlation between pulmonary function (PF) and health-related quality of life (HRQL) in patients after ARDS. DESIGN: Follow-up cohort study. SETTING: A 20-bed ICU of a university teaching hospital. PATIENTS: A cohort of 50 long-term survivors of ARDS. MEASUREMENTS AND RESULTS: Measurements of PF (FVC, FEV1, TLC, D(LCO)) and HRQL (SF-36 Health Status Questionnaire) were made 5.5 years (median value) after discharge from the ICU. Impairments in PF (defined as PF results below 80% of the predicted value) were frequent but generally mild. Twenty patients had a single PF impairment (with limitations in FEV1/FVC ratio in 12 patients being the most common), four patients had two (with D(LCO) and FEV1/FVC ratio impairment the most common) and three patients had pathologic results in three PF tests (FEV1/FVC ratio, TLC and capillary pO2 during exercise in one case, FVC, TLC and capillary pO2 during exercise in the second patient and FVC, TLC and D(LCO) in the third). Compared to normal controls, survivors of ARDS showed impairments in all SF-36 health dimensions (p < 0.001). Patients with multiple (> 1) PF impairments described the lowest HRQL with major limitations in all SF-36 categories (p < 0.037) including physical and mental summary scores (36.5 vs 46.9, p = 0.037 and 31.3 vs 51.4, p = 0.003) when compared to patients with no or only one PF impairment. CONCLUSIONS: Long-term survivors of ARDS have a significant reduction in HRQL and the presence of multiple PF impairments is associated with maximal decrements in HRQL.

Health-related quality of life and post-traumatic stress disorder in patients after cardiac surgery and intensive care treatment.
OBJECTIVES: Health-related quality of life and patient satisfaction have become important end points in cardiac surgery. Post-traumatic stress disorder has been described in patients with life-threatening heart disease. In this study, we investigated the occurrence of post-traumatic stress disorder in a sample of patients after cardiac surgery and compared health-related quality of life and patient satisfaction between patients with and without evidence of post-traumatic stress disorder. METHODS: We studied 80 patients serially admitted to the intensive care unit after cardiac surgery (bypass grafting, n = 51; aortic valve replacement, n = 29). Health-related quality of life was assessed with the use of the SF-36 Health Status Questionnaire. Post-traumatic stress disorder was measured with a previously validated instrument (the Post-Traumatic Stress Syndrome 10-Questions Inventory), and 20 different aspects of life satisfaction were quantified on a scale ranging from 0 to 10. For measurements of health-related quality of life and post-traumatic stress disorder, age- and gender-comparable healthy individuals, as well as patients with cardiovascular diseases, served as control groups. RESULTS: Patients who had cardiac surgery described high life satisfaction summary scores (156 of a maximum of 200 points) and only small impairments in physical and mental SF-36 summary scores when compared with healthy control groups (median reduction 7.15, P <.05). Patients with evidence of post-traumatic stress disorder (n = 15) reported the lowest SF-36 mental health summary scores when compared with patients without stress disorder (38.3 vs 48.4, P =.004) and rated their life satisfaction lower (121.5 vs 162.0, P =.002). CONCLUSIONS: Patients who have had cardiac surgery demonstrate a high life satisfaction with an acceptable degree of physical and mental health-related quality of life. Impairments in psychosocial function and life satisfaction were found in a subgroup of patients with evidence of post-traumatic stress disorder.

Treatment of depression with methylphenidate in patients difficult to wean from mechanical ventilation in the intensive care unit.
BACKGROUND: Mechanical ventilation is often required to support patients in the intensive care unit (ICU) with life-threatening cardiovascular, respiratory, or neuromuscular disorders. Occasionally, difficulties related to weaning patients from this support occur owing to depression. The traditional and newer-generation antidepressant drugs have a relatively long latency of response that interferes with rehabilitation attempts in the ICU. Psychostimulants such as methylphenidate show a rapid onset of antidepressant activity and a benign side effect profile. METHOD: As consulting psychiatrists in the consultation-liaison service of a university hospital, we treated 7 patients with complex ICU courses presenting prolonged mechanical ventilation and psychomotor retardation associated with markedly depressed mood (DSM-IV criteria) by giving them methylphenidate. Methylphenidate was started on the first day at a dose of 2.5 mg p.o. in the morning and was increased by 2.5 mg each day with twice-a-day dosing in the morning and at noon until the patient responded or showed side effects. A maximum dose of 15 mg/day was not exceeded. Outcome evaluation was performed using the Clinical Global Impressions scale. RESULTS: Five (71 %) of 7 patients showed marked or moderate improvement in mood and activity within 3 to 4 days, and discontinuation of ventilator support was achieved within 8 to 14 days. Side effects with these 5 patients were not encountered. Of the remaining 2 patients (29%), 1 developed psychomotor agitation and anxiety within 4 days. Another patient showed only minimal improvement with regard to activity. CONCLUSION: Methylphenidate might be a rapidly effective and safe treatment for depression in difficult-to-wean patients hospitalized for life-threatening medical illness in the ICU. Implications for future research for this population of patients warrant formal randomized, prospective, clinical case-control evaluation.

Sensitivity and specificity of a screening test to document traumatic experiences and to diagnose post-traumatic stress disorder in ARDS patients after intensive care treatment.
OBJECTIVE: Many survivors of critical illness and intensive care unit (ICU) treatment have traumatic memories such as nightmares, panic or pain which can be associated with the development of posttraumatic stress disorder (PTSD). In order to simplify the rapid and early detection of PTSD in such patients, we modified an existing questionnaire for diagnosis of PTSD and validated the instrument in a cohort of ARDS patients after long-term ICU therapy. DESIGN: Follow-up cohort study. SETTING: The 20-bed ICU of a university teaching hospital. PATIENTS: A cohort of 52 long-term survivors of the acute respiratory distress syndrome (ARDS). INTERVENTIONS AND MEASUREMENTS: The questionnaire was administered to the study cohort at two time points 2 years apart. At the second evaluation, the patients underwent a structured interview with two trained psychiatrists to diagnose PTSD according to Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria. The reliability and validity of the questionnaire was then estimated and its specificity, sensitivity and optimal decision threshold determined using receiver operating characteristic (ROC) curve analyses. RESULTS: The questionnaire showed a high internal consistency (Crohnbach's alpha = 0.93) and a high test-retest reliability (intraclass correlation coefficient alpha = 0.89). There was evidence of construct validity by a linear relationship between scores and the number of traumatic memories from the ICU the patients described (Spearman's rho = 0.48, p < 0.01). Criterion validity was demonstrated by ROC curve analyses resulting in a sensitivity of 77.0% and a specificity of 97.5% for the diagnosis of PTSD. CONCLUSIONS: The questionnaire was found to be a responsive, valid and reliable instrument to screen survivors of intensive care for PTSD.

Effects of noninvasive positive pressure ventilatory support in non-COPD patients with acute respiratory insufficiency after early extubation.
OBJECTIVE: To investigate the effects of noninvasive positive pressure ventilation (NPPV) on pulmonary gas exchange, breathing pattern, intrapulmonary shunt fraction, oxygen consumption, and resting energy expenditure in patients with persistent acute respiratory failure but without chronic obstructive pulmonary disease (COPD) after early extubation. DESIGN: Prospective study. SETTING: Multidisciplinary intensive care unit of a university hospital. PATIENTS: 15 patients after prolonged mechanical ventilation (> 72 h) with acute respiratory insufficiency after early extubation. INTERVENTIONS: Criteria for early extubation were arterial oxygen tension (PaO2) > or = 40 mm Hg (fractional inspired oxygen 0.21), arterial carbon dioxide tension (PaCO2) < or = 55 mm Hg, pH > 7.32, respiratory rate < or = 40 breaths per min, tidal volume (VT) > or = 3 ml/kg, rapid shallow breathing index < or = 190 and negative inspiratory force > or = 20 cmH2O. After extubation, two modes of NPPV were applied [continuous positive airway pressure (CPAP) of 5 cmH2O and pressure support ventilation (PSV) with 15 cmH2O pressure support]. MEASUREMENTS AND MAIN RESULTS: Oxygenation and ventilatory parameters improved during both modes of NPPV (p < 0.05): increase in PaO2 of 11 mm Hg during CPAP and 21 mm Hg during PSV; decrease in intrapulmonary shunt fraction of 7% during CPAP and 12% during PSV; increase in tidal volume of 1 ml/kg during CPAP and 4 ml/kg during PSV; decrease in respiratory rate 6 breaths/min during CPAP and 9 breaths/min during PSV. Oxygen consumption (15% during CPAP, 22% during PSV) and resting energy expenditure (12% during CPAP, 20% during PSV) were reduced (p < 0.05). PaCO2 decreased, whereas minute ventilation and pH increased during PSV (p < 0.05). The median duration of NPPV was 2 days. Two patients had to be reintubated. CONCLUSIONS: In non-COPD patients with persistent acute respiratory failure after early extubation, NPPV improved pulmonary gas exchange and breathing pattern, decreased intrapulmonary shunt fraction, and reduced the work of breathing.

Stress doses of hydrocortisone reverse hyperdynamic septic shock: a prospective, randomized, double-blind, single-center study.
OBJECTIVE: To investigate the effects of stress doses of hydrocortisone on the duration of vasopressor therapy in human septic shock. DESIGN: Prospective, randomized, double-blind, single-center study. SETTING: Twenty-bed multidisciplinary intensive care unit in a 1400-bed university hospital. PATIENTS: Forty consecutive patients who met the ACCP/SCCM criteria for septic shock. An additional criterion for inclusion in the study was vasopressor support and high-output circulatory failure with a cardiac index of >4 L/min/m2 after fluid resuscitation (pulmonary capillary wedge pressure: 12-15 mm Hg) and without the use of positive inotropes such as dobutamine or dopexamine. The primary study end point was the time to cessation of vasopressor support (norepinephrine or epinephrine in any dose, dopamine > or = 6 microg/kg/min). Secondary study end points were the evolution of hemodynamics and the multiple organ dysfunction syndrome (MODS). The severity of illness at recruitment was graded using the Acute Physiology and Chronic Health Evaluation II and the Simplified Acute Physiology Score II scoring systems. MODS was described by the Sepsis-related Organ Failure Assessment score. INTERVENTIONS: All eligible patients were prospectively randomized to receive either stress doses of hydrocortisone or placebo. Hydrocortisone was started with a loading dose of 100 mg given within 30 mins and followed by a continuous infusion of 0.18 mg/ kg/hr. When septic shock had been reversed, the dose of hydrocortisone was reduced to 0.08 mg/kg/hr. This dose was kept constant for 6 days. As soon as the underlying infection had been treated successfully or sodium serum concentrations had increased to >155 mmol/L, the hydrocortisone infusion was tapered in steps of 24 mg/day. Physiologic saline solution was the placebo. MEASUREMENTS AND MAIN RESULTS: Hemodynamic and oxygen-derived variables were measured at previously defined time points over a study period of 5 days. Relevant clinical and laboratory measurements were registered for a study period of 14 days to assess the evolution of organ dysfunction. Baseline data at recruitment did not differ between the two groups. Shock reversal was achieved in 18 of the 20 patients treated with hydrocortisone vs. 16 of the 20 patients treated with placebo. Hydrocortisone significantly reduced the time to cessation of vasopressor support. The median time of vasopressor support was 2 days (1st and 3rd Quartiles, 1 and 6 days) in the hydrocortisone-treated group and 7 days (1st and 3rd Quartiles, 3 and 19 days) in the placebo group (p = .005 Breslow test). There was a trend to earlier resolution of the organ dysfunction syndrome in the hydrocortisone group. CONCLUSIONS: Infusion of stress doses of hydrocortisone reduced the time to cessation of vasopressor therapy in human septic shock. This was associated with a trend to earlier resolution of sepsis-induced organ dysfunctions. Overall shock reversal and mortality were not significantly different between the groups in this low-sized single-center study.

The effect of stress doses of hydrocortisone during septic shock on posttraumatic stress disorder and health-related quality of life in survivors.
OBJECTIVES: The exposure to intense physical and psychological stress during intensive care can result in posttraumatic stress disorder (PTSD) in survivors. Cortisol is a biological stress mediator that can have a protective effect during severe stress. The administration of stress doses of hydrocortisone during treatment in the intensive care unit could theoretically result in a lower incidence of PTSD. We tested this hypothesis in survivors of septic shock. DESIGN: A retrospective case-controlled analysis. SETTING: A 20-bed multidisciplinary intensive care unit of a tertiary-care university hospital. PATIENTS: We identified 27 patients who received standard therapy for septic shock. These patients served as controls and were compared with an equal number of patients who received hydrocortisone in addition to standard treatment. These patients were selected from our database with regard to age (+/-4 yrs), gender, and cause of septic shock to be as similar as possible with control patients. INTERVENTIONS: Patients from the hydrocortisone group had received stress doses of hydrocortisone (100 mg bolus, followed by 0.18 mg/kg/hr) in addition to standard treatment. Patients from the control group received standard protocol-driven treatment only. PTSD was diagnosed with the Posttraumatic Stress Syndrome-10 inventory, a self-report scale for diagnosis of PTSD. Health-related quality of life was measured using the Medical Outcomes Study Short-Form Survey (Medical Outcomes Trust, Boston, MA), which consists of 36 questions. MEASUREMENTS AND MAIN RESULTS: Patients who received hydrocortisone during septic shock had a significantly lower incidence of PTSD than patients who received standard treatment only (5 of 27 vs. 16 of 27; p = .01) and had significantly higher scores on the mental health index of the Medical Outcomes Study Short-Form health-related quality-of-life questionnaire (68 vs. 44 points; p = .009). CONCLUSIONS: Data from this study support the hypothesis that the administration of stress doses of hydrocortisone in doses equivalent to the maximal endocrine secretion rate during septic shock reduces the incidence of PTSD and improves emotional well-being in survivors. This hypothesis should be tested in a prospective randomized trial.

[Health-related quality of life. Long-term survival in patients with ARDS following extracorporeal membrane oxygenation (ECMO)].
UNLABELLED: Treatment of severe acute respiratory distress syndrome (ARDS) with extracorporeal membrane oxygenation (ECMO) can be lifesaving but requires maximal use of intensive care resources over prolonged periods of time, resulting in high costs. Little is known about the health-related quality of life (HRQL) in long-term survivors. This case-controlled retrospective study was designed to assess the health-related quality of life in long-term survivors of ARDS and ECMO-therapy. METHODS: 14 long-term survivors of ARDS (APACHE II score = 24, Lung Injury Score = 3.25, median values) treated using ECMO between 1992 and 1995 (median time interval between data collection and discharge from the ICU 16 months) and 14 ARDS-patients conventionally treated during the same period (group I) were identified and completed the SF-36 Health Status Questionnaire (Medical Outcome Trust, Boston, USA). 14 healthy subjects (group II) were drawn at random from a large data base generated to provide normal values for the SF-36 in a German population. All three groups were comparable with respect to sex and age. RESULTS: Long-term survivors of ECMO-therapy reported significant reductions in physical functioning when compared with patients treated by mechanical ventilation alone (group I, -12.5%, p < 0.05) and with healthy controls (group II, -50%, p < 0.05) and showed a higher incidence of chronic physical pain (+5% and +24%, respectively, p < 0.05). There were no differences with regard to the mental health dimensions of the SF-36 (e.g. vitality, mental health index or social functioning) between ECMO-patients and all controls. Nine patients (64.3%) from the ECMO group versus all patients treated conventionally (group I) had full-time employment (p = 0.46, Chi2 test). CONCLUSIONS: The majority of long-term survivors of ECMO-treatment show good physical and social functioning, including a high rate of employment. The more aggressive approach of ECMO-therapy and a possibly more severe underlying disease process may explain impairments in health-related quality of life outcomes after ECMO-treatment. Despite these limitations, long-term survivors of ECMO-therapy are able to reach a highly satisfactory health-related quality of life.

Group A streptococcal toxic shock syndrome with severe necrotizing fasciitis following hysterectomy--a case report.
In the last 10 years an increasing number of cases of group A streptococcal toxic shock syndrome have appeared in various clinical settings. The manifestation of this syndrome includes rapidly progressive multiorgan failure and soft-tissue necrosis. This report presents a case of streptococcal toxic shock syndrome caused by Streptococcus pyogenes with severe necrotizing fasciitis of the abdominal wall following hysterectomy. Aggressive surgical intervention with debridement of all necrotic tissue necessitated resection of the complete abdominal wall (skin, subcutaneous tissue, muscle and peritoneum). The abdominal wall defect was covered with free myocutaneous flaps and split-skin grafts. Optimal treatment, including adequate antibiotic therapy and radical surgical intervention, is an indispensable prerequisite of successful outcome.
