OBJECTIVE: Carbapenem-resistant Acinetobacter baumannii (CR-Ab) is an important cause of infections in burn patients. This study aimed to characterize the antimicrobial susceptibility pattern of CR-Ab isolated from burns in Burn Intensive Care Unit (BICU) of the Trauma and Burn Centre of Ben Arous, to determine the prevalence of β-lactamase-encoding genes and to search eventual genetic relatedness of CR-Ab strains.
RESULTS: From 15 December 2016 to 2 April 2017, all nonduplicated CR-Ab isolated in burn patients in the BICU were screened by simplex Polymerase Chain Reaction (PCR) for the class A, B, C, and D β-lactamase genes. Sequencing was performed for NDM gene only. Genetic relatedness was determined by using pulsed field gel electrophoresis (PFGE) and by multilocus sequence typing. During the study period, 34 strains of CR-Ab were isolated in burns, mainly in blood culture (n = 14) and central vascular catheter (n = 10). CR-Ab strains were susceptible to colistin but resistant to amikacin (91%), ciprofloxacin (100%), rifampicin (97%), and trimethoprim-sulfamethoxazole (100%). All strains harbored blaOXA-51-like and blaOXA-23 genes, only or associated to blaGES (n = 26; 76%), blaADC (n = 20; 59%), blaPER-1 (n = 6; 18%) or/and blaNDM-1 (n = 3; 9%). PFGE identified 16 different clusters and revealed that most strains belonged to one major cluster A (n = 15; 44.1%). Among NDM-1 isolates, two were clonally related in PFGE and belonged to two single locus variant sequence type ST-6 and ST-85.
CONCLUSIONS: This is the first description of clonally related NDM-1 and OXA-23-producing A. baumannii strains in the largest Tunisian BICU associated with two single locus variant sequence types ST6 and ST85.

To describe the course of the outbreak and infection control measures to stop the spread of sequence type 15 OXA-23-producing Acinetobacter baumannii in the Burn Center of Uppsala University Hospital, between November 2014 and the end of April 2015.
Compliance with hand hygiene, dress code, and cleaning routines were reviewed, the ward\'s environment was systematically investigated to identify potential environmental sources. Sampling routines for A. baumannii, from patients and environment, were established, and the epidemiological relationship was analysed for all carbapenem-resistant A. baumannii isolates using arbitrarily primed polymerase chain reaction (AP-PCR) and pulsed-field gel electrophoresis (PFGE).
A total of 54 patients were treated at the burn intensive care unit during the studied, approximately five months period, and an OXA-23-producing A. baumannii was isolated from nine patients (9/54, 17%), whereof two died (2/9, 22.2%). All isolates shared identical PFGE-genotype patterns and belonged to sequence type 15; AP-PCR was eligible for prompt epidemiological investigations.
Higher awareness and increased compliance with hand hygiene and dress code as well as intensified cleaning protocols of the environment and equipment were successfully established and likely to have led to stop the spread of sequence type 15 OXA-23-producing Acinetobacter baumannii.

BACKGROUND: The treatment and management of massive burns, defined as burns affecting≥ 50% of total body surface area (TBSA) has considerably changed since the 90s. This study aimed at analyzing if the length of intensive care unit (ICU) stay, the success of skin grafting operations and the mortality changed in the last 18 years.
METHODS: Between 2000 and 2018, 77 patients were admitted for massive burns to the ICU of a university hospital. Transfers and early care withdrawal precluded inclusion for 38 patients, leaving 39 for analysis. Study variables were year of admission, demographics, burn characteristics, critical care treatment (fluid resuscitation, ventilation and nutrition) and surgical therapy. Association between outcomes and year of admission were assessed through correlation and logistic regression analysis. Potential confounders were assessed through stepwise linear regression.
RESULTS: Patients\' characteristics were stable over time with a median age of 36[25.0, 48.0] years, burns 65% [55.0, 83.0] TBSA and deep burns 55% [50.0, 68.0] TBSA . Length of ICU stay remained stable at 0.97 [0.6, 1.5] days/%TBSA. Mortality was stable as well. Energy and carbohydrate delivery decreased in parallel with the number of infectious episodes per patient. Number of operations was stable but the take rate of skin grafts increased significantly. The multivariate analysis retained year of admission, weight, total number of infections, daily lipid intakes and fluid resuscitation as independent predicting variables.
CONCLUSIONS: Length of ICU stay and mortality did not change over time but skin grafts take rates improved significantly.

Extensively drug resistant Acinetobacter baumannii (XDR-Ab), has emerged as an important pathogen in several outbreaks. The aim of our study was to investigate the eventual genetic relatedness of XDR-Ab strains recovered from burn patients and environment sites in the largest Tunisian Burn Intensive Care Unit (BICU) and to characterize β-lactamase encoding genes in these strains. Between March 04th, 2019 and April 22nd, 2019 an outbreak of XDR-Ab was suspected. Environmental screening was done. All isolates were screened by simplex PCR for β-lactamase genes. Genetic relatedness was determined by pulsed field gel electrophoresis (PFGE) of ApaI-digested total DNA. During the study period, 21 strains of A. baumannii were isolated in burn patients, mainly in blood culture (n = 7) and central vascular catheter (n = 6). All strains were susceptible to colistin but resistant to imipenem (n = 23), ciprofloxacin (n = 23), amikacin (n = 22), tigecyclin (n = 5) and rifampicin (n = 4). The blaOXA-51-like, blaOXA23, and blaADC genes were present in all strains. These resistance determinants were associated with blaPER-1 in 10 strains. The ISAba1 was inserted upstream of blaOXA-23 in all isolates. PFGE revealed two major clusters A (n = 11) and B (n = 5). This is the first description in Tunisia of clonally related PER-1 producing XDR-Ab in burn patients with probable environmental origin.

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.
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.
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.
Hot water scalds are associated with large TBSAs, long stays in the BICU, and worse outcomes compared to the other scald types.

Burn specialists have long recognized the need for and have role modeled a comprehensive approach incorporating relief of distress as part of care during critical illness. More recently, palliative care specialists have become part of the healthcare team in many U.S. hospitals, especially larger academic institutions that are more likely to have designated burn centers. No current literature describes the intersection of palliative care and burn care or integration of primary and specialist palliative care in this unique context. This Perspective gives an overview of burn care; focuses on pain and other symptoms in burn intensive care unit settings; addresses special needs of critically ill burned patients, their families, and clinicians for high-quality palliative care; and highlights potential benefits of integrating primary and specialist palliative care in burn critical care. MEDLINE and the Cumulative Index to Nursing and Allied Health Literature were searched, and an e-mail survey was used to obtain information from U.S. Burn Fellowship Program directors about palliative medicine training. The Improving Palliative Care in the Intensive Care Unit Project Advisory Board synthesized published evidence with their own research and clinical experience in preparing this article. Mortality and severe morbidity for critically ill burned patients remains high. American Burn Association guidelines lay the foundation for a robust system of palliative care delivery, embedding palliative care principles and processes in intensive care by burn providers. Understanding basic burn care, challenges for symptom management and communication, and the culture of the particular burn unit, can optimize quality and integration of primary and specialist palliative care in this distinctive setting.

BACKGROUND: Enhanced environmental cleaning practices are among the most accepted measures for controlling the spread of carbapenem-resistant Acinetobacter baumannii (CR-Ab).
OBJECTIVE: To evaluate the impact of heightened cleaning on an ongoing CR-Ab outbreak in a burn intensive care unit (BICU) of an Italian teaching hospital, where chlorhexidine-60% isopropyl alcohol was applied as a complementary disinfectant on high-touch surfaces.
METHODS: Compliance with the microbial limit proposed for the BICU by AFNOR-NF-S90-351 (20 colony-forming units/100cm2) was assessed by plate count, and compared with the results obtained with intracellular adenosine triphosphate (ATP) detection. Genotyping was performed using pulsed-field gel electrophoresis.
RESULTS: During the standard cleaning regimen, three out of 23 samples (13%) gave results over the AFNOR limit and five (21.7%) showed unacceptable ATP levels with 100 relative light units/100cm2 as the benchmark limit (sensibility 86.4%, specificity 92.2%). Following improvement of the cleaning procedure, only two samples out of 50 (4%) did not satisfy the microbiological criteria and seven (14%) exceeded the ATP limit. In a successive phase, eight of 30 samples collected showed unacceptable results (27%).
CONCLUSIONS: Adding chlorhexidine-60% isopropyl alcohol as complementary disinfectant proved to be effective for reducing environmental microbial contamination, ATP levels and CR-Ab infection/colonization in patients admitted to the BICU. Real-time monitoring by ATP assay was useful for managing the cleaning schedule and reducing hospital infections, although the calculated values must be interpreted as cleanliness indicators rather than risk indicators.

OBJECTIVE: To assess the effects of mobility training on severe burn patients in the Burn Intensive Care Unit (BICU).
METHODS: This was a retrospective cohort study. Severe burn patients with equal to or more than 50% Total Body Surface Area (TBSA) burns who received early rehabilitation in the BICU were included in this study. Based on the different early rehabilitation strategies during the two periods, patients admitted to the BICU from January 2011 to April 2013 were identified as the passive training cohort (n=49) while patients admitted to the BICU from May 2013 to December 2013 were identified as the mobility training cohort (n=24). Data on length of BICU stay, length of hospital stay, length of rehabilitation in the BICU, ventilator dependent days, strict bed rest time, range of motion (ROM), the Barthel Index (BI) and the Functional Independence Measure (FIM) were collected.
RESULTS: Compared with the passive training cohort, patients in the mobility training cohort had significantly shorter length of BICU stay (p=0.002), length of hospital stay (p=0.010), strict bed rest time (p<0.001) and length of rehabilitation in the BICU (p=0.026) with improved ROM of shoulder, wrist, hip, knee and ankle joints.
CONCLUSIONS: Mobility training in the BICU was shown to be feasible and effective in achieving better outcomes than passive training for severe burn patients.

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a systemic disease that can be associated with debilitating acute and chronic complications across multiple organ systems. As patients with acute SJS/TEN are often treated in a burn intensive care unit (BICU), we surveyed burn centers across the United States to determine their approach to the care of these patients. The goal of our study was to identify best practices and possible variations in the care of patients with acute SJS/TEN. We demonstrate that the method of diagnosis, use of systemic therapies, and involvement of subspecialists varied significantly between burn centers. Beyond supportive care provided to every patient, our data highlights a lack of standardization in the acute care of patients with SJS/TEN. A comprehensive guideline for the care of patients with acute SJS/TEN is indicated.

The high incidence of mortality in patients with severe burns can be attributed to bloodstream infections caused by drug-resistant microorganisms. Multilocus variable-number tandem repeat analysis (MLVA), multilocus sequence typing (MLST) and class 1 integron PCR amplification were performed to investigate an extensively drug-resistant Acinetobacter baumannii (XDR-AB) strain recovered from a blood culture of a patient admitted to a burn intensive care unit in St Petersburg (Russian Federation). This case study describes an XDR-AB strain of multilocus sequence type ST231 with a blaGES-12 gene cassette encoding a very potent ceftazidimase located inside of a composite class 1 integron. This is the first documented case of XDR-AB belonging to the international clonal lineage I in Russia.
