The performance of clinical risk scores in the diagnosis of necrotising fasciitis.

OBJECTIVE: Necrotising fasciitis (NF) is a quickly progressing and potentially life-threatening infection, involving the fascia and subcutaneous tissues. The diagnosis of this disease is challenging, especially due to a lack of specific clinical signs. In order to ensure a better and quicker identification of NF patients, a laboratory risk indicator score has been developed for NF (LRINEC). A variant has widened this score by adding clinical parameters (modified LRINEC). This study shows current outcomes of NF and compares the two scoring systems. METHODS: This study was conducted between 2011 and 2018, and included patient demographics, clinical presentations, sites of infection, comorbidities, microbiological and laboratory findings, antibiotic therapies and LRINEC as well as modified LRINEC scores. The primary outcome was in-hospital mortality. RESULTS: A cohort of 36 patients, diagnosed with NF, were included in this study. The mean hospital stay was 56 days (±38.2 days). The mortality rate in the cohort was 25%. The sensitivity of the LRINEC score was 86%. Calculation of the modified LRINEC score showed an improvement of the sensitivity to 97%. The average LRINEC score and modified LRINEC score for patients who died and who survived were equal (7.4 versus 7.9 and 10.4 versus 10.0, respectively). CONCLUSION: The mortality rate of NF remains high. The modified LRINEC score increased the sensitivity in our cohort to 97%, and this scoring system could be supportive in the diagnosis of NF for early surgical debridement.

Comparison of the characteristics of hot tap water scalds and other scalds in Germany.

BACKGROUND/AIM: Mortality associated with hot tap water scalds remains significant, owing to a lack of up-to-date regulations on tap water temperature. We aimed to evaluate the effect of hot tap water scalds on patients admitted to our adult burn intensive care unit (BICU), and compare them to those with other scald types. METHODS: We enrolled patients treated for scalds at the BICU of Cologne-Merheim Medical Center from 1989 to 2014, and retrospectively analyzed their age, sex-specific differences, characteristics, length of hospital stay, number of operations, and mortality. Patients were categorized into two groups: patients with hot tap water scalds and those with all other types of scalds. RESULTS: A total of 333 patients were enrolled. In 23.4% (n=78) of the cases, the scalds were associated with hot tap water. Such injuries were more commonly observed in older men than women. Hot tap water scalds involved a significantly higher total burned surface area (TBSA) than other scalds, with TBSA values of 24.0% and 15.9% for men, and 21.8% and 10.9% for women, respectively. Hot tap water scald patients had a greater number of surgeries and longer BICU stays (27.8 days vs 9.1 days), and significantly higher mortality values (30.8% (n=24) vs 4.7% (n=12)) than those with the other scald types. CONCLUSIONS: Hot water scalds are associated with large TBSAs, long stays in the BICU, and worse outcomes compared to the other scald types.

Characteristics and outcomes of patients with grill-related Burn injuries admitted to the Cologne Burn Center, Germany.

BACKGROUND: Grilling has become increasingly common in Germany. Although grilling is considered a non-negligible household burn hazard, few reports have assessed this type of injury. This study aimed to determine the patterns and characteristics of grill-related burn injuries and to compare these with other types of burn injuries. METHODS: This retrospective observational study included all grill-related burn injuries admitted to Cologne Merheim Burn Center during 1989-2017. The collected data were analyzed descriptively and compared statistically with other fire injuries. RESULTS: Of 1706 cases admitted with fire injuries during the study period, 160 (∼10%) involved grill-related injuries. Most cases (85%) involved men, with an average age of 34 years. Moreover, 48% and 38% of cases occurred in summer and spring, respectively. The most common mechanism of injury was ignition via fluid accelerant. The upper limb was the most commonly affected body part, followed by the head. Statistical analyses revealed that grill-related injuries were associated with a lower mean age and total body surface area, shorter in-hospital stay, and fewer complications than the other fire injury group. CONCLUSION: Grill-related injuries are a relatively common cause of admission to the Cologne Burn Center. Although grill-related injuries underwent a less aggressive approach than the other investigated fire injuries, the former represent a public health concern because they mainly affect the upper body, with both psychologic and aesthetic consequences. We recommend a German nationwide multi-centric study of the patterns and characteristics of burn injury.

Candida Antigen Titer Elevation and Mortality in Burn Patients.

BACKGROUND: Mortality in burn patients has several contributing factors as sex, age, degree of burns, or inhalation injuries. Usefulness of Candida antigen (CAG) titer is still being under debate to predict mortality. This study assessed correlation between CAG titer and mortality in burn patients. METHODS: From 1988 to 2011, 877 burn intensive care patients were evaluated for age, sex, total burn surface area (TBSA), multi organ failure (MOF), burn depth, escharotomy, fasciotomy, antibiotic use, co-morbidities, CAG titer and intubation. RESULTS: From 870 admitted patients, 190 patients were not enrolled. Increasing age was correlated with a higher mortality. The abbreviated burn severity index (ABSI) score of the deceased was 4 points and the TBSA was 20% higher than the survivors. The correlation for age, intubation, TBSA, inhalation injury, MOF, CAG titer, antibiotic use and escharotomy was significant. An increasing mortality was noted with antibiotic use and a CAG titer of 1:8 and higher. CAG titer of 1:8 and higher had a sensitivity of 51.1% and specificity of 86.3% for mortality. Multivariate analysis confirmed high influence of older age, MOF, comorbidities, antibiotic use and CAG titer of 1:8 and higher on mortality. There was a significant correlation for sex, younger age and CAG titer. CONCLUSION: CAG titers of 1:8 and higher might warrant beginning of antimycotic treatment in elderly patients with high TBSA to avoid increase in mortality.

Etiology, incidence and gender-specific patterns of severe burns in a German Burn Center - Insights of 25 years.

INTRODUCTION: Burns often require special treatment in specialized burn centers. One of the specialized German burn centers is located in Cologne-Merheim. Only little is known about the etiology of burns in Germany, their monthly distribution and changes over the past 25 years. METHODS: We therefore retrospectively analyzed the etiology for all patients treated at the burn intensive care unit (BICU) of Cologne in the last 25 years and categorized them into groups. Thereafter all groups were analyzed according to distribution of age, gender and occurrence. RESULTS: In this way we were able to show that the number of severe burns did not decrease over the time under evaluation and that it did not show seasonal variation. Injured females were older than males but fewer in number. The highest numbers of burns were related to fire, followed by electricity, hot liquids, chemicals and heat contact. Work-related burns occurred mostly with males. However, most of the burns were not work-related for either gender. CONCLUSION: The number of burns in Germany and in the world is still high, and prevention strategies do not always have the desired effect. This study aims to fill the gap in published burn knowledge in Germany by way of describing the gender differences and etiology characteristics. It can therefore help to identify risks and expand effective burn prevention strategies.

Pseudomonas aeruginosa bacteremia after burn injury: the impact of multiple-drug resistance.

To evaluate the clinical impact of multiple-drug resistance in burn patients with Pseudomonas aeruginosa (Pa) bacteremia. A retrospective cohort study in a 10-bed burn intensive care unit (BICU) was performed. Univariate and multivariate analyses were used to analyze the influence of multiple-drug resistance on mortality and length of BICU stay in Pa bacteremic patients. During a 21-year study period (1989-2009), 87 patients with Pa bacteremia were identified; 45 patients had multiple-drug resistant (MDR) strains and 42 susceptible strains. On comparison of the two populations, one with multiple-drug resistant strains and the other with the susceptible strains, the following parameters were found to be significantly different in the univariate analysis: age (32.7 vs 43.6 years; P = .013), sex (males: 91.1 vs 66.7%; P = .005), intubation status on admission (75.6 vs. 54.8%; P = .041), escharotomy (57.8 vs 33.3%; P = .022), burn size (51.0 vs 35.3% of TBSA; P = .002) and Abbreviated Burn Severity Index score (9.2 vs 8.1; P = .048). In terms of outcome parameters, multiple-drug resistance was not significantly related to mortality (adjusted odds ratio 1.076; 95% confidence interval [CI] 0.356-3.254; P = .897) and length of BICU stay after Pa bacteremia (Kaplan-Meier analysis log-rank test P = .945; Cox's proportional hazards regression hazards ratio, 0.994; 95% CI 0.513-1.925; P = .985) in the univariate and multivariate analyses. The data from this study suggest that multiple-drug resistance is not associated with significant increases in mortality and length of BICU stay among burn patients with Pa bacteremia.

Deep sternal osteomyelitis: an algorithm for reconstruction based on wound width.

Patients with sternum osteomyelitis are transferred to plastic surgery departments for wound coverage. Several options of flap coverage are known; however, various wound diameters need different flaps. In a retrospective study, 135 patients from 2006-2010 with deep sternal wound infections were evaluated. From 2006-2009 various flaps were used for wound coverage, as described in published reports. In 2010 a developed algorithm was used for defect coverage based on wound width using pectoralis muscle flaps or the latissimus dorsi muscle flap. Two groups of patients were analyzed, from 2006-2009 and 2010, and in a matched pair analysis patients with small wound width less than 6 cm, medium wounds widths between 6-12 cm, and large wound width larger than 12 cm. End-point was wound dehiscence larger than 1 cm. Statistical analysis was done by Mann Whitney U-test using the SPSS program. Forty-eight patients were included in the match from a total of 130 study patients. Statistical analysis did not show significant difference in patient population of the two groups. In the group with wound sizes less than 6 cm a significant difference was found when using the algorithm. In the other groups no statistically significant difference was seen; however lesser numbers in wound dehiscence were found. In addition, a significantly lesser length of stay was found in the ICU and length of the hospital stay for all groups treated according to the algorithm. A reduction of costs may be achieved when using the algorithm based on wound size.

Staphylococcus aureus bacteremia after thermal injury: the clinical impact of methicillin resistance.

OBJECTIVE: To evaluate the impact of methicillin resistance in Staphylococcus aureus bacteremia (SAB) on mortality and length of stay in burn patients. DESIGN: Retrospective cohort study. SETTING: A 750-bed tertiary care university hospital in Cologne, Germany. PATIENTS: Patients registered in the database of the burn intensive care unit (BICU) between 1989 and 2009 with complete data sets (n=1688). RESULTS: Over the 21-year study period, 74 patients with SAB were identified; 33 patients had methicillin-resistant S. aureus (MRSA) and 41 methicillin-susceptible S. aureus (MSSA). Comparing the MRSA with the MSSA population the following parameters were significantly different in the univariate analysis: BMI (27.2 kg/m(2) vs. 23.6 kg/m(2); P=0.05), extent of deep partial thickness burns (17.8% vs. 9.0% of total body surface area; P=0.007), antibiotic requirement on admission (45.5% vs. 22.0%; P=0.046), median length of hospitalization prior SAB (24 days vs. 7 days; P<0.001), packed red blood cells administration (47.6 units vs. 26.1 units; P=0.003), intubation requirement (100% vs. 80.5%; P=0.007), intubation period (43.5 days vs. 26.8 days; P=0.008), catecholamine requirement (90.9% vs. 61.0%; P=0.004), sepsis (60.6% vs. 34.1%; P=0.035) and organ failures (81.8% vs. 39.0%; P<0.001). Regarding outcome parameters, methicillin resistance was not significantly related with mortality (adjusted OR 1.55, 95% CI 0.56-4.28; P=0.40) and length of BICU stay after SAB (Kaplan-Meier analysis log-rank test P=0.32; Cox's proportional hazards regression HR 1.22, 95% CI 0.65-2.27, P=0.535) in the univariate and multivariate analyses. CONCLUSION: Our data suggest that methicillin resistance is not associated with significant increases in mortality and length of BICU stay among burn patients with SAB.

Early single-shot intravenous steroids do not affect pulmonary complications and mortality in burned or scalded patients.

BACKGROUND AND OBJECTIVES: Inhalation injury, especially in combination with cutaneous burns, is the major cause of morbidity and mortality in patients admitted to burn care centers. Either with or without the presence of a cutaneous burn, inhalation injury contributes to high risk for developing severe pulmonary complications. Steroids may reduce a prolonged and destructive inflammatory response to toxic or allergic substances. The objective of this study was to evaluate the effect of early single-shot intravenous steroids on pulmonary complications and mortality in burned or scalded patients with or without inhalation injury. METHODS: Retrospective analysis of a prospective single center database of patients registered between 1989 and 2011 who were admitted to the intensive care unit of our burn care center after burn or scald injury. Uni-variate statistical analysis was performed comparing two groups (steroid treated vs. non steroid treated patients) with regard to clinical outcome. Main parameters were sepsis, mortality and pulmonary complications such as pneumonia, ALI and ARDS. Multi-variate analysis was used by logistic regression with mortality and pulmonary complications as the dependent variables to identify independent risk factors after burn or scald injuries. RESULTS: A total of 1637 patients with complete data were included in the present analysis. 199 (12.2%) received single-shot intravenous steroids during the prehospital phase of care. In 133 (66.8%) of these patients, inhalation injury was diagnosed via bronchoscopy. Steroid treated patients had sustained a significantly higher severity of burn than non-steroid treated patients (Abbreviated Burn Severity Index 7.1±3 vs. 6.0±2.9; p<0.001). In a multivariate analysis using a logistic regression model early intravenous steroid treatment had no significant effect on pulmonary complications and mortality. CONCLUSIONS: In our single center cohort of burned and scalded patients single-shot intravenous steroids during the pre-hospital phase of care was not associated with pulmonary complications or mortality.

Incidence and treatment of burns: a twenty-year experience from a single center in Germany.

OBJECTIVE: To analyze trends in incidence and treatment of thermal injuries over the last two decades. METHODS: We retrospectively reviewed our local single center database of patients with thermal injuries admitted to the burn intensive care unit (BICU) of the Cologne-Merheim Medical Center (University Hospital of Witten/Herdecke). The cohort was divided into two groups according to the decade of admission and the epidemiology and clinical course of the patient sample admitted during the period 1991-2000 (n=911) was compared to that of 2001-2010 (n=695). RESULTS: The following variables were significantly different in the bivariate analysis: mean age (39.8 years vs. 44.0 years), burn size of total body surface area (23.2% vs. 18.0%) and size of 3rd degree burns (9.6% vs. 14.9%). The incidence of inhalation injury was significantly lower in the last decade (33.3% vs. 13.7%) and was associated with a shorter duration of mechanical ventilation (10.8 days vs. 8.5 days). The ABSI-score as an indicator of burn severity declined in the second period (6.3 vs. 6.0) contributing partially to the decline of BICU length of stay (19.1 days vs. 18.8 days) and to the mortality rate decrease (18.6% vs. 15.0%). CONCLUSION: The severity of burn injuries during the last two decades declined, probably reflecting the success of prevention campaigns. Concerning mortality, the chance of dying for a given severity of injury has decreased.

Failure of secondary wound closure after sternal wound infection following failed initial operative treatment: causes and treatment.

BACKGROUND: Patients transferred to Plastic Surgery Departments for sternum osteomyelitis have a high morbidity of about 3%. Despite several known options for sternal wound coverage and salvage operations, wound dehiscence or wound necrosis can occur, increasing patient morbidity. PATIENTS AND METHODS: One hundred thirty-five patients admitted between January 2007 and December 2010 were evaluated in a retrospective study for wound dehiscence after salvage wound coverage at our institution. Various flaps were applied, such as pectoralis major myocutaneous pedicled flaps, pectoralis major muscle pedicled flaps, latissimus dorsi pedicled flaps, greater omental flaps, and vertical rectus abdominis muscle and transverse rectus abdominis muscle flaps. Inclusion criteria were sternal wound infection, bacterial wound infection, previous wound debridement outside our institution, vacuum-assisted closure device wound treatment at our institution, and secondary flap closure of the sternal defect at our institution. A multivariate regression analysis was performed. RESULTS: One hundred thirty patients met the inclusion criteria. In all patients, bacterial wound colonization was shown. Forty patients showed wound dehiscence after closure at our institution. Reasons for wound dehiscence were attributed to wound size, >4 different species of bacteria colonizing the wound, gram-negative bacteria, Candida albicans, intensive care unit stay, and female gender. Interestingly, wound dehiscence was not significant correlated to obesity, smoking, atherosclerosis, renal insufficiency or type of closure influenced significantly, or necrosis. CONCLUSIONS: Female patients after CABG, with large sternal wounds infected with gram-negative bacteria and candida, have an 85% risk of wound dehiscence after flap coverage for sternal wound infection.

Suicide by burning: epidemiological and clinical profiles.

Self-immolation constitutes a rare form of suicide in developed countries, though it accounts for unique injury characteristics in the burn intensive care unit. The aim of this study was to present the epidemiological and clinical features of patients burned during a suicidal attempt seen in a North Rhine-Westphalia burn intensive care unit (BICU). To address this aim, we undertook a 21-year retrospective study involving patients with thermal injuries admitted to the largest burn unit in Germany. A total of 125 suicide-related burn victims were identified in the study period (9.4%). Comparing the self-immolation group with the rest burn patient cohort, suicide victims were more likely to be single and to act under the influence of alcohol. The suicidal group had a larger extent of burns, higher incidence of inhalation injury, required more surgical procedures, catecholamines, blood transfusions, and a longer BICU stay. Their clinical course was complicated by prolonged intubation period, higher rate of multiple drug-resistant bacteria acquisition and sepsis, leading to a higher mortality rate. Although the proportion of self-immolation victims among all burned patients is not high, the markedly higher severity of their burns and their poorer quality of outcomes makes them an important clinical subgroup for further study.

Histometric and histomorphologic comparison of combustion and ambustion using in vivo reflectance-confocal microscopy.

BACKGROUND: When combustion and ambustion induce a superficial injury, they are summarized as superficial burns, regardless of the underlying cause. Reflectance-confocal microscopy (RCM) allows noninvasive imaging of the human skin on morphological features. We hypothesized that combustion and ambustion have different histomorphological effects on the human skin. METHODS: Superficial burns caused by combustion (CO-group, five females, three males; aged 26.8 +/- 14.2 years) and caused by ambustion (AM-group, four females, four males; aged 28.1 +/- 13.8 years) were evaluated 24 h after injury. The following parameters were obtained using RCM on injured and noninjured (control) site: horny layer thickness, epidermal thickness, granular cell size, basal layer thickness. RESULTS: Compared with the controls (12.8 +/- 2.5 microm), horny layer thickness decreased significantly to 10.6 +/- 2.1 microm in the CO-group, whereas it increased significantly to 17.8 +/- 2.8 microm in the AM-group. The epidermal thickness did not differ significantly in CO-group (47.9 +/- 2.1 microm) and AM-group (49.0 +/- 3.1 microm), however, both increased significantly compared with the controls (42.7 +/- 1.6 microm). The basal layer thickness increased more in AM-group (17.0 +/- 1.2 microm) compared to CO-group (15.4 +/- 1.1 microm). Both differed significantly compared with their controls (13.9 +/- 0.9 microm). The granular cell size increased significantly in both groups compared to the controls (721 +/- 42 microm), however, a significantly higher increase was observed in CO-group compared to AM-group (871 +/- 55 microm vs. 831 +/- 51 microm). CONCLUSIONS: RCM evaluates significant histomorphological differences in superficial burns caused by combustion and ambustion. The term "superficial burn" should consider the underlying cause and thus supplemented by the term "combustion" or "ambustion."

New multifactorial burn resuscitation formula offers superior predictive reliability in comparison to established algorithms.

UNLABELLED: The Parkland-Baxter formula is a widely utilized resuscitation guideline for the initial management of fluid deficits in burn victims. Implementation of resuscitation formulas has helped to reduce the incidence of shock and hypovolemic organ failure such as acute renal failure in the setting of burn trauma. However, it has been shown that indiscriminate implementation of these formulas may inappropriately suit individual patient's requirements. In our experience resuscitation by the Parkland formula often forced corrections in order to reach predefined resuscitation goals. OBJECTIVE: Given these findings we felt the need to refine formula based resuscitation strategies. PATIENTS AND MEASUREMENTS: Reviewing a subset of 81 burn admissions we screened for predictive parameters in addition to total body surface area burned (TBSA burned) and body weight influencing resuscitation volume requirements. DESIGN: Using multivariate linear regression analysis (MRA) various parameters were integrated in a stepwise forward mathematical selection procedure resulting in a modified resuscitation formula. MAIN RESULTS: A new formula including body weight, TBSA burned, inhalation injury (IHI), high blood alcohol level (BAL) and a compensating factor for advanced age was set up. The new formula was compared to the original Parkland formula. Both were assessed for predictive reliability (PR(+/-20%)). Using this strategy we were able to improve PR(+/-20%) from 28.4% to 51.9%. CONCLUSIONS: Optimal fluid resuscitation of severe burn victims is a complex clinical challenge. Rigid-formula based resuscitation schemes often fail to match all subtleties of current clinical practice but need to provide a reliable starting point for fluid resuscitation. We demonstrate a new multifactorial formula resulting in a better guide to initial fluid resuscitation.

Severe brain damage by current flow after electrical burn injury.

Patients sustaining high-voltage electrical injury may experience neurological sequelae. The exact mechanism of nervous cell destruction is an ongoing subject of research, frequently a combination of both thermal and nonthermal causes. In this report, brain damage of the entire right hemisphere according to the current flow with isolated affection of pre- and postcentral gyrus of left hemisphere is described. Clinical findings, including neurological symptoms, radiographic images, and autopsy results, are presented. Possible mechanisms of brain destruction solely caused by current flow are discussed.

One year ago not business as usual: wound management, infection and psychoemotional control during tertiary medical care following the 2004 Tsunami disaster in southeast Asia.

INTRODUCTION: Following the 2004 tsunami disaster in southeast Asia severely injured tourists were repatriated via airlift to Germany. One cohort was triaged to the Cologne-Merheim Medical Center (Germany) for further medical care. We report on the tertiary medical care provided to this cohort of patients. METHODS: This study is an observational report on complex wound management, infection and psychoemotional control associated with the 2004 Tsunami disaster. The setting was an adult intensive care unit (ICU) of a level I trauma center and subjects included severely injured tsunami victims repatriated from the disaster area (19 to 68 years old; 10 females and 7 males with unknown co-morbidities). RESULTS: Multiple large flap lacerations (2 x 3 to 60 x 60 cm) at various body sites were characteristic. Lower extremities were mostly affected (88%), followed by upper extremities (29%), and head (18%). Two-thirds of patients presented with combined injuries to the thorax or fractures. Near-drowning involved the aspiration of immersion fluids, marine and soil debris into the respiratory tract and all patients displayed signs of pneumonitis and pneumonia upon arrival. Three patients presented with severe sinusitis. Microbiology identified a variety of common but also uncommon isolates that were often multi-resistant. Wound management included aggressive debridement together with vacuum-assisted closure in the interim between initial wound surgery and secondary closure. All patients received empiric anti-infective therapy using quinolones and clindamycin, later adapted to incoming results from microbiology and resistance patterns. This approach was effective in all but one patient who died due to severe fungal sepsis. All patients displayed severe signs of post-traumatic stress response. CONCLUSION: Individuals evacuated to our facility sustained traumatic injuries to head, chest, and limbs that were often contaminated with highly resistant bacteria. Transferred patients from disaster areas should be isolated until their microbial flora is identified as they may introduce new pathogens into an ICU. Successful wound management, including aggressive debridement combined with vacuum-assisted closure was effective. Initial anti-infective therapy using quinolones combined with clindamycin was a good first-line choice. Psychoemotional intervention alleviated severe post-traumatic stress response. For optimum treatment and care a multidisciplinary approach is mandatory.

The long-distance tertiary air transfer and care of tsunami victims: injury pattern and microbiological and psychological aspects.

OBJECTIVE: On December 26, 2004, a giant earthquake shocked Southeast Asia, triggering deadly flood waves (tsunami) across the Indian Ocean. More than 310,000 people have been reported dead and millions left destitute. Shortly thereafter, European governments organized airborne home transfer of most severely injured tourists using MedEvac aircraft. On arrival, patients were distributed to various medical centers. One cohort of the severely injured was admitted to the Cologne-Merheim Medical Center (Germany) for further surgical and intensive care treatment. The objective of this report was to characterize typical injury patterns along with microbiological findings and psychoemotional aspects unique to the tsunami disaster. DESIGN: Observational study. SETTING: Adult intensive care unit of a university hospital. PATIENTS: Seventeen severely injured tsunami victims were screened on arrival for characteristic injury patterns. In parallel, multifocal microbiological assessment was performed to identify pathogens responsible for high-level wound contamination. INTERVENTIONS: Standard clinical management. MEASUREMENTS AND MAIN RESULTS: The predominant pattern of injury comprised multiple large-scale soft-tissue wounds (range, 2 x 3 to 60 x 60 cm) of lower extremities (88%), upper extremities (29%), and head (18%). Additional injuries included thoracic trauma with hemopneumothorax and serial rib fractures (41%) and peripheral bone fractures (47%). A major problem associated with wound management was significant contamination. Microbiological assessment identified a variety of common (Pseudomonas 54%, Enterobacteriae 36%, Aeromonas spp. 27%) but also uncommon isolates that were often multiply resistant (multiply resistant Acinetobacter and extended-spectrum beta-lactamase-positive Escherichia coli, 18% each). Upper respiratory tract specimens contained a high rate of multiply resistant Acinetobacter species but also methicillin-resistant Staphylococcus aureus, Aeromonas hydrophilia, Pseudomonas species, and Candida albicans. Apart from these findings, all patients displayed severe signs of posttraumatic stress response. CONCLUSIONS: Individuals who survived their initial injuries and who were evacuated to Europe had traumatic injuries to head, chest, and limbs that were often contaminated with highly resistant bacteria.
