The objective of this work was to find out the bacteriological profile and risk factor for burn patients. Sixty burn patients were investigated during July 2014 to May 2015. Specimens were collected in the form of wound swabs. The prospective study showed that one third of the patients below 10 years old belong the highest burn infections. The rate of burn infections was higher (61.67%) in female compared to male patients. Respondents under primary level were the major victims (28.33%). On the basis of occupational status, student showed the highest (30%) infection. Maximum (48.33%) patients were injured by first degree burn. Hot liquids (scald) was found as one of the main causes of burn which was 50% prevalent. Forensic background explained maximum burn injuries were accidental (88.34%). Most of the children were the main victims during playing (36.67%) followed by working persons (25%). Pseudomonas spp (73%) was found to be the most common isolated microorganisms followed by Klebsiella spp (6.67%), Staphylococcus aureus (6.67%), Escherichia coli (6.67%), Proteus spp (5%) and Enterobacter (1. 6%). Some medical devices like floor, bed, water etc. were detected as positive sources of organisms. By antibiotic susceptibility tests it was found that Pseudomonas are resistant to ceftriaxone (100%) followed by ceftazidime (93%) and sensitive to colistin (90%). In the case of Staphylococcus aureus, 100% are resistant to amoxyclave and 100% are sensitive to ciprofloxacin. Asian J. Med. Biol. Res. June 2019, 5(4): 336-342

Rokas Bagdonas, Algimantas Tamelis, Rytis Rimdeika, Mindaugas Kiudelis Įvadas / tikslas Didžiausia nudegimų chirurgijos problema yra infekcija, nuo kurios miršta daugiau kaip 50% visų nudegusių pacientų. Nudegimų žaizda greitai infekuojasi, kadangi žaizdos aplinka yra ideali mikroorganizmams atsirasti ir daugintis. Studijoje, patvirtintoje Universiteto etikos komiteto, analizuojami nudegę pacientai ir iš nudegimo žaizdų išskirti patogenai. Pacientai ir metodai Mes analizavome 2246 nudegusius pacientus (amžiaus vidurkis – 27 metai), gydytus KMU Chirurgijos klinikose 1997–2002 metais. Nudegimo sunkumas buvo vertintas pagal Amerikos nudegimų asociacijos (ABA) schemą. 2462 nudegimo žaizdos pasėliai (2246 pacientų) buvo paimti steriliu tamponu ir pasėti 5% kraujo ir MacConkey terpėse. Rezultatai Iš nudegusių pacientų 1447 (74%) buvo vyrai ir 799 (26%) – moterys (p < 0,001). Pacientų amžius – nuo 2 iki 47 metų. 1261 (56%, p < 0,05) pacientai patyrė lengvą, 522 – vidutinį ir 463 – sunkų kūno nudegimą. 2130 pasėliai (86,5%), paimti iš 2462 nudegimo žaizdų, buvo teigiami. Iš 2130 teigiamų pasėlių Staphylococcus aureus išskirtas 1110 (52,1%) pasėliuose, iš jų MRSA – 498 (23,4%). Išvados Jauni vyrai dažniausiai patiria lengvus kūno nudegimus. Nudegimo žaizda dažniausiai infekuojasi S. aureus mikroorganizmais. MRSA yra pagrindinis ligoninės patogenas, infekuojantis nudegimo žaizdą. Prasminiai žodžiai: nudegimo sunkumas, nudegimo žaizdos patogenai, išskirti sukėlėjai Analysis of burn patients and the isolated pathogens Rokas Bagdonas, Algimantas Tamelis, Rytis Rimdeika, Mindaugas KiudelisKaunas Medical University, Clinic of Surgery,Eivenių str. 2, LT-50009, Kaunas, LithuaniaE-mail: [email protected] Background / objective The major challenge for a burn team is infection, which is known to cause over 50% of burn deaths. Burns become infected, because the environment at the site of the wound is ideal for the proliferation of infecting organisms. This study, approved by the regional Ethics Committee, analyzes the features of burned patients and the rates of pathogens isolated from burn wounds. Patients and methods We studied 2246 burn patients (mean age 27 years) admitted to the tertiary academic hospital in 1997–2002. The differentiation of the severity of burn injury was based on the scheme of the American Burn Association (ABA). 2462 surface swabs for microbiological analysis were taken from all 2246 patients. The wound area was swabbed with an alginate swab and cultured in 5% blood and MacConkey agar. Results There were 1447 (74%) men and 799 (26%) women (p < 0.001), age range 2–47 years. There were 1261 patients (56%, p < 0.05) with minor, 522 with moderate and 463 with major burn injuries. 2130 swabs (86.5%) out of 2462 burn wound surface swabs were positive. Out of 2130 isolates positive for pathogenic bacterial culture, there were 1110 (52.1%) isolates positive for Staphylococcus aureus infection. The rate of MRSA was 23.4% (498 isolates). Conclusions Young male patients mostly have a minor burn injury. Burn wounds are most commonly infected with S. aureus. MRSA is still the main hospital pathogen in burns. Keywords: severity of the burn injury, burn swabs, isolated pathogens

Antibiotic resistance has become a major world health challenge and has limited the ability of physician's treatment. Staphylococcus aureus the most notorious pathogens causes morbidity and mortality especially in burn patients. However, Staphylococcus aureus rapidly acquired resistance to multiple antibiotics. Vancomycin, a glycopeptide antibiotic remains a drug of choice for treatment of severe Methicillin Resistance S. aureus infections. This study aimed to detect the emergence of beta-lactam and glycopeptide resistance genes. 50 clinical specimens of S. aureus collected from burn patients in burn and plastic surgery units in Sulaimani-Iraq city. All specimens were confirmed to be positive for S. aureus. All the isolates were assessed for their susceptibility to different antibiotics depending on NCCL standards, followed by Extended Spectrum Beta Lactamase detection by double disk diffusion synergy test. The production of β- lactamases was evaluated in the isolated strains by several routine methods and polymerase chain reaction. Among the isolates 94% were Methicillin resistance and 34.28% were Extended Spectrum Beta Lactamase producer. PCR based molecular technique was done for the bla genes related to β- lactamase enzymes by the specific primers, as well as genes which related to reduced sensitivity to Vancomycin were detected. The results indicated that all isolated showed the PBP1, PBP2, PBP3, PBP4, trfA and trfB, graSR, vraS except the vraR gene and the prolonged therapy of Methicillin resistance infection with teicoplanin have been associated with progress of resistance and the rise of tecoplanin resistance may be a prologue to evolving Vancomycin resistance. In conclusion, beta-lactam over taking can rise Vancomycin- Intermediate S. aureus strains leading to appearance of Vancomycin resistance although the treatment of Vancomycin resistant infections is challenging.

Abstract Introduction In burn patients, vitamin D deficiency has been associated with increased incidence of sepsis. The objective of this study was to assess the impact of vitamin D deficiency in adult burn patients on hospital length of stay (LOS). Methods This was a multi-center retrospective study of adult patients at 7 burn centers admitted between January 1, 2016 and July 25, 2019 who had a 25-hydroxyvitamin D (25OHD) concentration drawn within the first 7 days of injury. Patients were excluded if admitted for a non-burn injury, total body surface area (TBSA) burn less than 5%, pregnant, incarcerated, or made comfort care or expired within 48 hours of admission. The primary endpoint was to compare hospital LOS between burn patients with vitamin D deficiency (defined as 25OHD &lt; 20 ng/mL) and sufficiency (25OHD ≥ 20 ng/mL). Secondary endpoints include in-hospital mortality, ventilator-free days of the first 28, renal replacement therapy (RRT), length of ICU stay, and days requiring vasopressors. Additional data collected included demographics, Charlson Comorbidity Index, injury characteristics, form of vitamin D received (ergocalciferol or cholecalciferol) and dosing during admission, timing of vitamin D initiation, and form of nutrition provided. Dichotomous variables were compared via Chi-square test. Continuous data were compared via student t-test or Mann-Whitney U test. Univariable linear regression was utilized to identify variables associated with LOS (p &lt; 0.05) to analyze further. Cox Proportional Hazard Model was utilized to analyze association with LOS, while censoring for death, and controlling for TBSA, age, presence of inhalation injury, and potential for a center effect. Results Of 1,147 patients screened, 412 were included. Fifty-seven percent were vitamin D deficient. Patients with vitamin D deficiency had longer LOS (18.0 vs 12.0 days, p &lt; 0.001), acute kidney injury (AKI) requiring RRT (7.3 vs 1.7%, p = 0.009), more days requiring vasopressors (mean 1.24 vs 0.58 days, p = 0.008), and fewer ventilator free days of the first 28 days (mean 22.9 vs 25.1, p &lt; 0.001). Univariable analysis identified burn center, AKI, TBSA, inhalation injury, admission concentration, days until concentration drawn, days until initiating supplementation, and dose as significantly associated with LOS. After controlling for center, TBSA, age, and inhalation injury, the best fit model included only deficiency and days until vitamin D initiation. Conclusions Patients with thermal injuries and vitamin D deficiency on admission have increased length of stay and worsened clinical outcomes as compared to patients with sufficient vitamin D concentrations.

With a reduction in the mortality rate of burn patients, length of stay (LOS) has been increasingly adopted as an outcome measure. Some studies have attempted to identify factors that explain a burn patient’s LOS. However, few have investigated the association between LOS and a patient’s mental and socioeconomic status. There is anecdotal evidence for links between these factors; uncovering these will aid in better addressing the specific physical and emotional needs of burn patients and facilitate the planning of scarce hospital resources. Here, we employ machine learning (clustering) and statistical models (regression) to investigate whether segmentation by socioeconomic/mental status can improve the performance and interpretability of an upstream predictive model, relative to a unitary model. Although we found no significant difference in the unitary model’s performance and the segment-specific models, the interpretation of the segment-specific models reveals a reduced impact of burn severity in LOS prediction with increasing adverse socioeconomic and mental status. Furthermore, the socioeconomic segments’ models highlight an increased influence of living circumstances and source of injury on LOS. These findings suggest that in addition to ensuring that patients’ physical needs are met, management of their mental status is crucial for delivering an effective care plan.

Abstract For medical and social reasons, it is important that burn patients attend follow up appointments (FUAs). Our goal was to examine the factors leading to missed FUAs in burn patients. A retrospective chart review was conducted of adult patients admitted to the burn center from 2016-2018. Data collected included burn characteristics, social history, and zip code. Data analysis was conducted using chi-square, Wilcox Rank Sum tests, and multivariate regression models. A total of 878 patients were analyzed, with 224 (25.5%) failing to attend any FUAs and 492 (56.0%) missing at least one appointment (MA). Patients who did not attend any FUAs had smaller burns (4.5 (8)% vs. 6.5 (11)% median (inter quartile range)), traveled farther (70.2 (111.8) vs. 52.5 (76.7) miles), and were more likely to be homeless (22.8% vs. 6.9%) and have drug dependence (47.3% vs. 27.2%). Patients who had at least one MA were younger (42 (26) vs. 46 (28) years) and more likely to be homeless (17.5% vs. 2.6%) and have drug dependence (42.5% vs. 19.4%). On multivariate analysis, factors associated with never attending a FUA were: distance from hospital (odds ratio (OR) 1.004), burn size (OR 0.96), and homelessness (OR 0.33). Factors associated with missing at least one FUA : age (OR 0.99), drug dependence (OR 0.46), homelessness (OR 0.22), and ED visits (OR 0.56). A high percentage of patients fail to make any appointment following their injury and/or have at least one MA. Both FUAs and MAs are influenced by social determinants of health.

ABSTRACTAmikacin clearance can be increased in burn injury, which is often complicated by renal insufficiency. Little is known about the impact of renal replacement therapies, such as continuous venovenous hemofiltration (CVVH), on amikacin pharmacokinetics. We retrospectively examined the clinical pharmacokinetics, bacteriology, and clinical outcomes of 60 burn patients given 15 mg/kg of body weight of amikacin in single daily doses. Twelve were treated with concurrent CVVH therapy, and 48 were not. The pharmacodynamic target of ≥10 for the maximum concentration of drug in serum divided by the MIC (Cmax/MIC) was achieved in only 8.5% of patients, with a small reduction ofCmaxin patients receiving CVVH and no difference in amikacin clearance. Mortality and burn size were greater in patients who received CVVH. Overall, 172 Gram-negative isolates were recovered from the blood cultures of 39 patients, with amikacin MIC data available for 82 isolates from 24 patients. A 10,000-patient Monte Carlo simulation was conducted incorporating pharmacokinetic and MIC data from these patients. The cumulative fraction of response (CFR) was similar in CVVH and non-CVVH patients. The CFR rates were not significantly improved by a theoretical 20 mg/kg amikacin dose. Overall, CVVH did not appear to have a major impact on amikacin serum concentrations. The low pharmacodynamic target attainment appears to be primarily due to higher amikacin MICs rather than more rapid clearance of amikacin related to CVVH therapy.

Abstract The hypermetabolic response from burn injury is the highest of the critically ill patient population. When coupled with the hypermetabolic response, preexisting malnutrition may increase the hospital resources used. The goal of this study was to evaluate the rate of malnutrition in burn patients and the associated hospital resource utilization.We collected prospective data on burn patients ≥ 18 years with a burn ≥ 10% TBSA admitted to a regional burn center. Demographics, %TBSA, co-morbidities, length of stay (LOS) and standardized LOS (LOS/%TBSA) were evaluated on 49 patients. A multivariable regression model was constructed. Nutrition assessment was completed within 24-48 hours of admission including an SGA (Subjective Global Assessment) classification. SGA A (well-nourished) was compared to SGA B and C (malnourished). Fourteen patients (28.6%) in this study were malnourished. Malnourished patients were not statistically different with respect to median age (50 versus 39; p = 0.08] and BMI (22.9 versus 26.5; p = 0.08) compared to the well-nourished group. However, malnourished patients had significantly longer median LOS (21.0 versus 11.0 days, p = 0.01) and LOS/%TBSA (1.69 versus 0.83, p = 0.001) than the well-nourished group. Being malnourished was a significant independent predictor of above median LOS/%TBSA (p=0.027) with an odds ratio (OR) of 5.61 (95% C.I. 1.215-25.890).The rate of malnutrition is important given the high metabolic demands of these patients. Malnutrition increased the resource requirements via higher standardized LOS. This underscores the importance of completing SGA on admission to identify malnutrition early on to optimize nutrition intervention during the patients’ hospital stay.

IntroductionThe Emergency Management of Severe Burns (EMSB) referral criteria have been implemented for optimal triaging of burn patients. Admission to a burn centre is indicated for patients with severe burns or with specific characteristics like older age or comorbidities. Patients not meeting these criteria can also be treated in a hospital without burn centre. Limited information is available about the organisation of care and referral of these patients. The aims of this study are to determine the burn injury characteristics, treatment (costs), quality of life and scar quality of burn patients admitted to a hospital without dedicated burn centre. These data will subsequently be compared with data from patients with<10% total bodysurface area (TBSA) burned who are admitted (or secondarily referred) to a burn centre. If admissions were in agreement with the EMSB, referral criteria will also be determined.Methods and analysisIn this multicentre, prospective, observational study (cohort study), the following two groups of patients will be followed: 1) all patients (no age limit) admitted with burn-related injuries to a hospital without a dedicated burn centre in the Southwest Netherlands or Brabant Trauma Region and 2) all patients (no age limit) with<10% TBSA burned who are primarily admitted (or secondarily referred) to the burn centre of Maasstad Hospital. Data on the burn injury characteristics (primary outcome), EMSB compliance, treatment, treatment costs and outcome will be collected from the patients’ medical files. At 3 weeks and at 3, 6 and 12 months after trauma, patients will be asked to complete the quality of life questionnaire (EuroQoL-5D), and the patient-reported part of the Patient and Observer Scar Assessment Scale (POSAS). At those time visits, the coordinating investigator or research assistant will complete the observer-reported part of the POSAS.Ethics and disseminationThis study has been exempted by the medical research ethics committee Erasmus MC (Rotterdam, The Netherlands). Each participant will provide written consent to participate and remain encoded during the study. The results of the study are planned to be published in an international, peer-reviewed journal.Trial registration numberNTR6565.

Introduction: Infections are a major problem and the presence of drug-resistant microorganisms has significant clinical and economic impact. The present study aims to evaluate the epidemiological profile of “problem” microorganisms isolated in a hospital in the north of Portugal.Material and Methods: All isolated microorganisms were analyzed, between January 2014 and June 2015. Data obtained was then processed using statistical software.Results: We analyzed 8146 microbiological isolations and found a prevalence of 23% of ‘problem’ microorganisms (in descending order of frequency: Enterococcus, Pseudomonas, Staphylococcus aureus e Streptococcus pneumonia), 57.55% of which isolated in male patients. The most frequent mechanism of drug resistance for the overall sample was the production of extended-spectrum beta-lactamase, and resistance to oxacillin for ‘problem’ microorganisms.Discussion: In this sample, we observed a much higher prevalence of ‘problem’ microorganisms than that reported in other countries, which shows the need of improvement of surveillance mechanisms and treatment of these cases. Microorganisms that showed higher resistance were Staphylococcus aureus (resistant to oxacillin) and Enterococcus (resistant to vancomycin). Those were isolated in patients with a higher mean age compared to non-resistant microorganisms. Most of these microorganisms were isolated in hospitalized patients or intermediate and intensive care units, what relates them with healthcare associated infections.Conclusion: The prevalence of infection by ‘problem’ microorganisms during the studied period was 23%. The detection and control of the spread of these microorganisms are paramount due to its impact on health costs, morbidity and survival of patients.

Background: Osteomyelitis is an inflammatory process caused by microorganism infection that leads to bone destruction. Osteomyelitis may affect all bones, particularly long bones, and infects all ages. This disease is hard to diagnose and the treatment is complex due to the disease’s heterogenicity, pathophysiology, clinical presentation, and management. This study aimed to determine the profile of osteomyelitis inpatients and outpatients presented to the Orthopedic Clinic of Dr. Hasan Sadikin General Hospital Bandung, IndonesiaMethods: This was a descriptive cross-sectional study conducted from July to October 2019 using the total sampling method. Data were collected from the medical records of osteomyelitis inpatients and outpatients presented to the Orthopedic Clinic of Dr. Hasan Sadikin General Hospital Bandung, Indonesia from 2017–2018. Data were then analyzed descriptively and the results were presented in frequencies.Result: In total, 90 data were retrieved. Most of data presented male patients (n= 69, 76.7%) with the age range of 20–29 years old (24.4%). The majority of these patients experienced chronic onset of disease (94.4%) located on the tibia (51.1%), which was caused by a post-operative procedure (61.1%). The most common treatment was operative procedure without antibiotic beads (51.1%). Staphylococcus aureus was the common pathogens identified in these patients (22.2%).Conclusion: The majority of osteomyelitis patients are males in productive age with chronic onset of disease located on the tibia caused by a post-operative procedure. Staphylococcus aureus is the common pathogen involved and the most common treatment is an operative procedure without antibiotic beads.
