Abstract
Acute phase and resuscitation after burn trauma are challenging even for specialised burn centres due to the individual onset and differences compared with other forms of shock. The guidelines of the German Society of Burn Medicine (DGV) cover the scientific basis of modern burn treatment. Nevertheless, uncertainty remains regarding the detailed practical handling. This expert consensus focuses on best practices for the treatment of patients with major burns in specialised burn centres and by clinical first responders.

Positive outcomes following Autologous Matrix-Induced Chondrogenesis (AMIC) in the treatment of retropatellar chondral lesions: a retrospective analysis of a patient registry. BMC Musculoskelet Disord 2023; 24:964. [PMID: 38082264 PMCID: PMC10712071 DOI: 10.1186/s12891-023-06923-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Accepted: 09/25/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND The patellofemoral joint is a challenging environment for treating chondral defects. Among the surgical options for the treatment of chondral defects, the single-stage Autologous Matrix-Induced Chondrogenesis (AMIC) procedure uses a porcine collagen I/III membrane to enhance bone-marrow stimulation. However, longer term outcomes data are rare for this specific indication. In order to provide real-world information, an ongoing registry has been established to record patient data and outcomes when AMIC is used to treat chondral and osteochondral lesions. METHODS Patient data were retrieved from an ongoing, prospective, multisite registry of patients who had undergone AMIC treatment of chondral defects. We identified 64 patients who had undergone AMIC for patellofemoral chondral defects and for whom pre-operative and at least 1 post-operative score were available were included in this retrospective data analysis. Outcomes were assessed via the KOOS, VAS pain, and the Lysholm scores. Outcomes at the post-operative time-points were analysed using a factorial ANOVA with post-hoc testing while linear regression was used to assess associations between the change in the Lysholm score and lesion size. RESULTS There was a significant improvement in Lysholm, VAS pain, and KOOS scores from pre-operative to the 1st year post-operative (p < 0.001), and this was maintained during the follow-up. CONCLUSIONS The forces exerted on the patellofemoral joint make this a challenging scenario for chondral repair. Our data demonstrates that the AMIC procedure with a collagen I/III membrane is an effective treatment for retropatellar cartilage lesions, and provides reliable results, with decreased pain and improved function. Importantly, these improvements were maintained through the follow-up period.

Abstract
OBJECTIVE Reliable outcome measures are essential to predict the success of cartilage repair techniques. Histology is probably the gold standard, but magnetic resonance imaging (MRI) has the potential to decrease the need for invasive histological biopsies. The 3D magnetic resonance observation of cartilage repair tissue (MOCART) score is a reliable yet elaborate tool. Moreover, literature is controversial concerning the correlation of histology and MRI. DESIGN To test the applicability of the International Cartilage Regeneration and Joint Preservation Society (ICRS) II and MOCART 3D score for the evaluation of aged osteochondral regenerates in a large animal model, and to identify correlating histological and MRI parameters. Osteochondral defects in medial femoral condyles of n = 12 adult sheep were reconstructed with biodegradable bilayer implants. About 19.5 months postoperation, n = 10 joints were analyzed with MRI (3D MOCART score). Histological samples were analyzed using the ICRS II score; both pre- and post-training. The intraclass correlation coefficient, the inter-rater reliability, and the 95% confidence interval were calculated. Matching histological and MRI parameters were tested for correlation. RESULTS We found a statistically significant correlation of all histological parameters. MRI parameters reflecting "overall" assessments had very strong inter-rater correlations. Statistically significant strong correlations were found for the MRI parameters defect filling, cartilage interface, bone interface, and surface. For defect overall (MRI) and overall assessment (ICRS II), we found a significant yet mild correlation. CONCLUSIONS The ICRS II and the 3D MOCART score are applicable to aged osteochondral regenerates. Prior training on the scoring systems is essential. Select MRI and histological parameters correlate; however, the only statistically significant correlation was found for overall assessment.

Abstract
BACKGROUND Anterior cruciate ligament (ACL) tear is the most frequent ligamentous injury of the knee joint. Autografts of hamstring (HS) or quadriceps tendons (QT) are used for primary ACL reconstruction. In this study, we planned to examine whether harvesting an HS graft is related to a deficit in dynamic knee stabilisation and strength revealed by dynamic valgus as compared with QT graft or the uninjured leg. Furthermore, if this deficit exists, is it compensated by higher neuromuscular activity of the quadriceps muscle? MATERIALS AND METHODS Adult patients who had undergone ACL reconstruction with QT or HS autografts were included in this two-armed cohort study. Clinical outcome was assessed by clinical data analysis, physical examination and the Lysholm Score and Knee Injury and Osteoarthritis Score (KOOS). In addition, gait analysis and non-invasive surface electromyography were performed. RESULTS A complete data set of 25 patients (QT: N = 8, HS: N = 17) was analysed. There was no significant demographic difference between the groups. Time between surgery and follow-up was significantly longer for the QT group. Significant differences regarding clinical outcome were not found between the treated and untreated leg or between the two groups, with excellent scores at the time of follow-up. Gait analysis revealed no significant differences of varus-valgus angles. Significant differences in surface electromyography were only found in the QT group with increased vastus medialis obliquus activity of the treated legs (p < 0.01). CONCLUSIONS Our results suggest that harvesting of HS grafts for primary ACL reconstruction will not lead to a medial collapse and consequently impaired medial stabilisation of the knee when compared with QT grafts.

The predictive role of Interleukin 6 in burn patients with positive blood cultures. INTERNATIONAL JOURNAL OF BURNS AND TRAUMA 2021; 11:123-130.

Abstract
Interleukin 6 (IL-6) is an established biomarker of inflammation with one of the earliest responses in sepsis. Serum levels can easily be measured within a few hours. The clinical significance of IL-6 in the early stage of sepsis in burned patients has not yet been confirmed. The purpose of our research was to investigate the predictive value of IL-6 for positive blood cultures in comparison to Procalcitonin (PCT), white blood cell (WBC) count, body temperature and the Sequential Organ Failure Assessment (SOFA) score in the presence of suspected sepsis in burn patients. In a retrospective study, we included all patients admitted to a regional burn centre in a 7-year period. Patients with a clinical suspicion of sepsis and complete laboratory tests underwent further analysis. Patients were categorized following culture results into either positive or negative bloodstream infection (BSI or non-BSI) groups. 39 of the 101 included patients had positive blood cultures (BSI). The serum IL-6 levels were significantly higher in the BSI group [1047 (339.9; 9000.5) vs. 198.5 (112.4; 702.5) ng/l; P = 0.001]. Receiver operating characteristic (ROC) curve analysis showed an AUC of 0.7 (59; 80.8%). The optimal IL-6 cut-off level was 312.8 ng/l (sensitivity 79.5%, specificity 56.5%). Other biomarkers (PCT, WBC), the maximum body temperature and increase of SOFA score were not different between the groups. IL-6 can be used to predict a positive blood culture even in the early stage of suspected sepsis in burned patients. In this context, other biomarkers (PCT, WBC) and body temperature are of limited clinical utility.

Abstract
Abstract
Background
It is unknown whether lung-protective ventilation is applied in burn patients and whether they benefit from it. This study aimed to determine ventilation practices in burn intensive care units (ICUs) and investigate the association between lung-protective ventilation and the number of ventilator-free days and alive at day 28 (VFD-28).
Methods
This is an international prospective observational cohort study including adult burn patients requiring mechanical ventilation. Low tidal volume (VT) was defined as VT ≤ 8 mL/kg predicted body weight (PBW). Levels of positive end-expiratory pressure (PEEP) and maximum airway pressures were collected. The association between VT and VFD-28 was analyzed using a competing risk model. Ventilation settings were presented for all patients, focusing on the first day of ventilation. We also compared ventilation settings between patients with and without inhalation trauma.
Results
A total of 160 patients from 28 ICUs in 16 countries were included. Low VT was used in 74% of patients, median VT size was 7.3 [interquartile range (IQR) 6.2–8.3] mL/kg PBW and did not differ between patients with and without inhalation trauma (p = 0.58). Median VFD-28 was 17 (IQR 0–26), without a difference between ventilation with low or high VT (p = 0.98). All patients were ventilated with PEEP levels ≥5 cmH2O; 80% of patients had maximum airway pressures <30 cmH2O.
Conclusion
In this international cohort study we found that lung-protective ventilation is used in the majority of burn patients, irrespective of the presence of inhalation trauma. Use of low VT was not associated with a reduction in VFD-28.

The initial validation of a novel outcome measure in severe burns- the Persistent Organ Dysfunction +Death: Results from a multicenter evaluation. Burns 2020; 47:765-775.

Abstract
INTRODUCTION A need exists to improve the efficiency of clinical trials in burn care. The objective of this study was to validate "Persistent Organ Dysfunction" plus death as endpoint in burn patients and to demonstrate its statistical efficiency. METHODS This secondary outcome analysis of a dataset from a prospective international multicenter RCT (RE-ENERGIZE) included patients with burned total body surface area >20% and a 6-month follow-up. Persistent organ dysfunction was defined as persistence of organ dysfunction with life-supportiing technologies and ICU care. RESULTS In the 539 included patients, the prevalence of 0p p+ pdeath was 40% at day 14 and of 27% at day 28. At both timepoints, survivors with POD (vs. survivors without POD) had a higher mortality rate, longer ICU- and hospital-stays, and a reduced quality of life. POD + death as an endpoint could result in reduced sample size requirements for clinical trials. Detecting a 25% relative risk reduction in 28-day mortality would require a sample size of 4492 patients, whereas 1236 patients would be required were 28-day POD + death used. CONCLUSIONS POD + death represents a promising composite outcome measure that may reduce the sample size requirements of clinical trials in severe burns patients. Further validation in larger clinical trials is warranted. STUDY TYPE Prospective cohort study, level of evidence: II.

Abstract
Objective: Severe burn injuries are associated with a rapid escalating hypermetabolic state and catabolism of muscle mass. To ameliorate this process a standardized approach using pharmacological and non-pharmacological interventions was implemented within a single burns center. Whilst individual components of this standardized package are well documented in the literature, their collective or bundled effect has not as yet been assessed. The aim of this study was to evaluate the efficacy of this standardized bundle of metabolic modulators and assess the safety of including the anabolic steroid oxandrolone within it. Methods: This retrospective observational study constituted all patients in whom the metabolic bundle including oxandrolone therapy was applied. The other elements of the metabolic bundle consisted of early surgical burn excision within seven days to completion, early active mobilization, increased ambient room temperature, expediated carbohydrate and protein rich enteral feeding with glutamine and trace element supplements (such as copper and zinc). Finally, administration of propranolol as a non-selective beta-blocker. Data collection was through review of the patient data management system focusing on the outcome criteria and hepatic blood values. Results: The study looked at fifty consecutive patients meeting the inclusion criteria. Median patient age and burned total body surface area (TBSA) were 62 years [51.75; 73] and 33.75% [24.75; 51] respectively with an abbreviated burn severity index (ABSI) of 10 [9; 10.25]. Definitive surgical burn wound excision was completed in 44 patients [88%] within 7 days. 39 patients (78%) received propranolol over a therapeutic period of 29 days [19; 44]. Glutamine was supplemented in 45 patients (90%), while zinc and copper were applied to 42 (84%) and 31 (62%) respectively. Significant low zinc values were noted at therapeutic onset (6.5 mmol/l [4.7; 7.9]) requiring sustained substitution over 37.5 days [22; 46.75]). In respect of the inclusion criteria, all patients received oxandrolone at 20 mg/day [20; 20]. This was commenced on day 6.5 [4; 14] post burn injury and continued over 26 days [19; 31]. Despite a transitory elevation of hepatic enzyme values (ALT, GGT), these were only clinically relevant (>10 µmol/l*S) in 2.4% and 4.6% of all measurements respectively. None were sufficiently of concern to merit cessation of treatment. Conclusion: The application of a standardised bundle of metabolic treatment options of severe burns injured patients is reliable, repeatable and safe. Potential concerns of oxandrolone treatment regarding hepatic compromise remain unfounded.

Abstract
INTRODUCTION Burn-injured patients are at particularly high risk of infection; as such one would expect an increased requirement of antibiotics compared to other intensive care patients. There is no data in the literature investigating this hypothesis in Germany. The aim of this study was to determine the antibiotic consumption in severe burn patients and to compare this data with those from surgical intensive care units. PATIENTS AND METHODS The retrospective study included 136 patients treated in the period from 2013 to 2016 due to a severe burn in the ICU intensive care unit of a regional burn centre. The use of antibiotics was recorded using the electronic medical record. The number of daily doses in Recommended Daily Dose (RDD) and Defined Daily Dose (DDD) based on patient days was calculated. RESULTS Median [interquartile range] age and total burned surface area were 56.5y [43-75y] and 17 % [8,75; 31] with an ABSI 7 [6; 9]. Antibiotic therapy was given to 82 patients (60.3 %). Antibiotic consumption totaled 77.38 RDD/100 PT or 937.64 DDD/1000 PT. This result was marginally lower than for surgical intensive care units. The most frequently used antibiotics in the burn care setting were fluorquinolones (16.90 RDD/100 PT, 259.91 DDD/1000 PT), followed by carbapenems (12.76 RDD/100 PT, 128.44 DDD/1000 PT) and aminopenicillins/ BLI (11.54 RDD/100 PT, 115.39 DDD/1000 PT). Whilst, the most frequently detected pathogens were Staphylococcus aureus (54.4 %), Enterococcus faecalis (54.4 %), E. coli (37.5 %) and Pseudomonas aeruginosa (36.8 %). CONCLUSION The total antibiotic consumption in severe burns was not increased compared to other surgical intensive care patients. With regard to individual substance classes, peculiarities can be identified reflecting the particular germ spectrum in this cohort.

Abstract
BACKGROUND Electrical injuries represent life-threatening emergencies. Evidence on differences between high (HVI) and low voltage injuries (LVI) regarding characteristics at presentation, rhabdomyolysis markers, surgical and intensive burn care and outcomes is scarce. METHODS Consecutive patients admitted to two burn centers for electrical injuries over an 18-year period (1998-2015) were evaluated. Analysis included comparisons of HVI vs. LVI regarding demographic data, diagnostic and treatment specific variables, particularly serum creatinine kinase (CK) and myoglobin levels over the course of 4 post injury days (PID), and outcomes. RESULTS Of 4075 patients, 162 patients (3.9%) with electrical injury were analyzed. A total of 82 patients (50.6%) were observed with HVI. These patients were younger, had considerably higher morbidity and mortality, and required more extensive burn surgery and more complex burn intensive care than patients with LVI. Admission CK and myoglobin levels correlated significantly with HVI, burn size, ventilator days, surgical interventions, amputation, flap surgery, renal replacement therapy, sepsis, and mortality. The highest serum levels were observed at PID 1 (myoglobin) and PID 2 (CK). In 23 patients (14.2%), cardiac arrhythmias were observed; only 4 of these arrhythmias occurred after hospital admission. The independent predictors of mortality were ventilator days (OR 1.27, 95% CI 1.06-1.51, p = 0.009), number of surgical interventions (OR 0.47, 95% CI 0.27-0.834, p = 0.010) and limb amputations (OR 14.26, 95% CI 1.26-162.1, p = 0.032). CONCLUSIONS Patients with electrical injuries, HVI in particular, are at high risk for severe complications. Due to the need for highly specialized surgery and intensive care, treatment should be reserved to burn units. Serum myoglobin and CK levels reflect the severity of injury and may predict a more complex clinical course. Routine cardiac monitoring > 24 h post injury does not seem to be necessary.

A sirs-based automated alarm system for the diagnosis of sepsis after burn injury. ANNALS OF BURNS AND FIRE DISASTERS 2017; 30:177-184.

Abstract
The present study examined the effectiveness of an automated systemic inflammatory response syndrome (SIRS)-based alarm system for the early detection of sepsis in adult burn patients. In addition, the relevance of the sepsis criteria from the American Burn Association (ABA) and the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) for this patient group was determined. In this prospective observational study, we included 41 consecutive patients who were admitted to our burn ICU within a one-year period. SIRS alarms were calculated for these patients according to predefined criteria using the PREDEC ALARM automated alarm system and alarms generated according to ABA criteria and daily Sequential Organ Failure Assessment (SOFA) results. The alarms were not visible to the treating doctors and nurses. The alarms identified were related to episodes of sepsis with positive blood cultures. Twenty-one sepsis events were recorded in 41 patients. The receiver operating characteristic (ROC) curve revealed an area under the curve (AUC) of 0.72 for alarms using 2 SIRS criteria, 0.77 for 3 SIRS criteria, and 0.61 for 4 SIRS criteria. AUC values of 0.53 and 0.59 were calculated for the ABA criteria and Sepsis-3 definition, respectively. An alarm system using 3 SIRS criteria proved to be suitable for the early detection of sepsis in burn patients. The frequent number of false alarms requires further refinement of the alarm system. Based on the results of our study, the ABA criteria and the Sepsis-3 definition provide no advantages over the SIRS criteria in the early diagnosis of sepsis after burn injury.

Abstract
Objectives The monitoring of fracture healing is a complex process. Typically, successive radiographs are performed and an emerging calcification of the fracture area is evaluated. The aim of this study was to investigate whether different bone healing patterns can be distinguished using a telemetric instrumented femoral internal plate fixator. Materials and Methods An electronic telemetric system was developed to assess bone healing mechanically. The system consists of a telemetry module which is applied to an internal locking plate fixator, an external reader device, a sensor for measuring externally applied load and a laptop computer with processing software. By correlation between externally applied load and load measured in the implant, the elasticity of the osteosynthesis is calculated. The elasticity decreases with ongoing consolidation of a fracture or nonunion and is an appropriate parameter for the course of bone healing. At our centre, clinical application has been performed in 56 patients suffering nonunion or fracture of the femur. Results A total of 39 cases of clinical application were reviewed for this study. In total, four different types of healing curves were observed: fast healing; slow healing; plateau followed by healing; and non-healing. Conclusion The electronically instrumented internal fixator proved to be valuable for the assessment of bone healing in difficult healing situations. Cost-effective manufacturing is possible because the used electronic components are derived from large-scale production. The incorporation of microelectronics into orthopaedic implants will be an important innovation in future clinical care. Cite this article: B. Kienast, B. Kowald, K. Seide, M. Aljudaibi, M.

Abstract
BACKGROUND Patients with pulmonary hypertension (PH) are at high risk when undergoing surgery. Up to one-third of patients suffer complications; recent studies report a mortality rate of 1 to 7%. Frequent events are deterioration of right heart function and infectious or bleeding complications. METHODS Data of patients (age ≥ 18) with precapillary PH who need to undergo elective surgery between January 2006 and March 2015 were included in this retrospective analysis. All patients who were planned for surgery underwent the same procedure. First, patients were evaluated in the PH center. Thereafter, PH-relevant data were discussed with the surgeon/anesthesiologist team for risk-adapted planning of anesthesia and intervention. The present analysis comprises patient characteristics and information about surgery and post-interventional course. RESULTS This study analyzes 31 surgical procedures carried out in PH patients (male: n = 8; PH-group I: n = 23, group III: n = 3, group IV: n = 5, mean age: 59.5 ± 15.3 years). Patients were characterized by compromised hemodynamics and exercise capacity: pulmonary vascular resistance: 805.4 ± 328.5 dyn*s*cm(-5), mean pulmonary arterial pressure: 46.3 ± 9.3 mmHg, 6-minute walking distance: 350.3 ± 123.3 m.The majority of interventions were performed under general anesthesia (n = 24). In 25 cases, the intraoperative monitoring was complemented with right heart catheterization.Eight interventions were associated with complications, three of which were serious. One patient died postoperatively owing to sepsis and right heart failure. CONCLUSION A careful and structured planning of surgical interventions in patients with PH and the choice of surgical procedure and anesthesia adapted to the conditions of PH might help avoid complications. Further multicentric studies are needed.

Multimodal evoked potential monitoring in asleep patients versus neurological evaluation in awake patients during carotid endarterectomy: a single-centre retrospective trial of 651 patients.

Abstract
BACKGROUND A controversy exists regarding which monitoring technique is superior in cases in which general anesthesia (GA) is necessary for carotid endarterectomy (CEA). Multimodal evoked potential (mEP) monitoring was investigated under GA during CEA and compared with a historical control group undergoing neurological evaluations awake under loco-regional anesthesia (LA). METHODS We retrospectively studied 651 patients undergoing elective CEA. In groupHISTORY (N.=349; 1997-1999) LA was provided using superficial or deep/superficial cervical plexus blocks. In groupmEP, (N.=302; 2009-2013) GA was performed by administering remifentanil/propofol infusion. The multimodal EPs included the median-nerve-somatosensory and motor evoked potentials. The primary outcome was the rate of technical failure. The arterio-arterial shunt rate and immediate postoperative motor outcomes were also compared. RESULTS GroupmEP showed a significantly lower rate of technical failure (OR 0.17; CI 0.03-0.6; P=0.002). Because the groups differed systematically, logistic regression analysis was used to compare shunt rates and motor outcomes. Since shunt rates were 8.3% (groupmEP) versus 8.2% (groupHISTORY), but logistic regression model showed significant differences (OR 3.77; CI 1.67-8.95; P=0.001) correct comparison was impossible. Immediate postoperative deficits were 4.3% (groupmEP) and 4.9% (groupHISTORY); logistic regression analysis: transient OR 0.77, CI 0.28 to 0.22, P=0.61 and permanent OR 0.37, CI 0.02-7.74, P=0.49. CONCLUSION Monitoring mEPs was associated with less technical failure than awake evaluation and showed similar motor outcomes. Because the groups differed systematically, the interpretation of shunt rates was impossible. Monitoring mEP should be considered to detect intraoperative ischemia in cases in which patients undergo CEA under GA.

Abstract
Introduction: It is known that pulmonary hypertension is associated with worse outcome in both cardiac and non-cardiac surgery. The aims of our retrospective analysis were to evaluate the outcomes of our patients with pulmonary hypertension undergoing major orthopedic surgery and to give experience-based recommendations for the perioperative management. Material and methods: From 92 patients with pulmonary hypertension undergoing different kinds of surgical procedures from 2011–2014 in a tertiary academic hospital we evaluated 16 patients with major orthopedic surgery for perioperative morbidity and mortality. Results: Regarding the in-hospital morbidity and mortality, one patient died postoperatively due to pulmonary infection and right heart failure (6.25%) and 6 patients suffered significant postoperative complications (37.5%; bleeding = 1, infection = 1, wound healing deficits = 3; dysrhythmia = 1). Conclusion: Our data show that major orthopedic surgery is feasible with satisfactory outcome even in cases of severe pulmonary hypertension by an individualized, disease-adapted interdisciplinary treatment concept.

Abstract
BACKGROUND A variety of crystalloids are available during fluid resuscitation of the severely burnt patient. There is a paucity of literature evidence on the comparative influence of these with regard to clinical outcomes. Significant differences in crystalloids may be clinically relevant given the large volumes employed during shock resuscitation. METHODS The study compared two groups of severely burnt patients (TBSA 20-70%). Prospectively 40 consecutive patients treated with Ringer's acetate (RA group) against a retrospective control group of 40 patients treated with Ringer's lactate (RL group). Outcome parameters analysed included Sequential Organ Failure Assessment (SOFA)-scores at Days 3 and 7 after injury, mortality at 28 and 60 days, electrolyte and renal function, infection rates, cumulative volume administration and duration of ventilator support. RESULTS Groups RA and RL were comparable w.r.t. age, total body surface area burn size and ABSI. SOFA-scores on Day 1 of admission also showed no significant difference but were significantly lower in RA group between the 3rd and 6th day. By Day 7 these differences could be attributed as a group effect (P=0.019). In particular low cardiovascular organ function scores contributed to this. Total crystalloid use within the first 28 days were equal in both but differed within the RA group having lower observed volumes of colloid and incidence of blood transfusion. Furthermore group RA had distinctly higher levels of platelets throughout treatment. Elevated lactate levels were noted in RL group during the initial three days. Survival rates at 28 days and 60 days showed no significant difference. CONCLUSION Ringer's acetate solution is a suitable medium for the initial fluid management of the acutely burnt patient. In comparison to Ringer's lactate solution the study revealed lower SOFA-scores for Ringer's acetate solution (ClinicalTrials.gov number, NCT00609700).

Abstract
Burn wound infections remain the most important factor limiting survival in burn intensive care units. Large wound surface, impaired immune systems, and broad-spectrum antibiotic therapy contribute to the growth of opportunistic fungal species. Faced with challenging fluid resuscitation, wound excision and cardiopulmonary stabilization, mycosis in burns are likely to be underestimated. Diagnostic performance can sometimes be delayed because clinical signs are unspecific and differentiation between colonization and infection is difficult. Therapeutic measures range from infection prophylaxis over treatment with antifungal agents towards radical amputation of infected limbs. New methods of early and reliable detection of fungal organisms, as well as the use of novel antifungal substances, are promising but require wider establishment to confirm the beneficial effects in burn patients. This review aims to highlight the main important aspects of fungal infections in burns including incidence, infection control, diagnostic and therapeutic approaches, prognosis and outcomes.

Abstract
Objectives Osteochondral injuries, if not treated adequately, often lead
to severe osteoarthritis. Possible treatment options include refixation
of the fragment or replacement therapies such as Pridie drilling,
microfracture or osteochondral grafts, all of which have certain
disadvantages. Only refixation of the fragment can produce a smooth
and resilient joint surface. The aim of this study was the evaluation
of an ultrasound-activated bioresorbable pin for the refixation of
osteochondral fragments under physiological conditions. Methods In 16 Merino sheep, specific osteochondral fragments of the medial
femoral condyle were produced and refixed with one of conventional
bioresorbable pins, titanium screws or ultrasound-activated pins.
Macro- and microscopic scoring was undertaken after three months. Results The healing ratio with ultrasound-activated pins was higher than
with conventional pins. No negative heat effect on cartilage has
been shown. Conclusion As the material is bioresorbable, no further surgery is required
to remove the implant. MRI imaging is not compromised, as it is
with implanted screws. The use of bioresorbable pins using ultrasound
is a promising technology for the refixation of osteochondral fractures.

Abstract
Infections are a great diagnostic and therapeutic challenge in intensive care patients with burn injuries. The major problems are due to bacteria with hospital-acquired multiresistance to antibiotics but fungal and viral infections may also be life-threatening. The main key points addressing pharmacotherapy with antibiotic, antifungal and antiviral agents in this special setting are exact diagnosis, early therapy with suitable drugs, adequate duration of treatment and adequate doses based on pharmacokinetic and pharmacodynamic characteristics of these compounds. The latter parameters are significantly altered in burn patients and show a wide interindividual and intraindividual variation in drug response as a result of the characteristic phases of burn injury. Drug concentration analysis may help to avoid inadequate dosing. In this review the main characteristics of burn injuries and the pharmacology of antibiotics, antifungal and antiviral agents in these patients are presented.

Abstract
The peroxisome proliferator-activated receptors (PPARs), PPARα, PPARδ, and PPARγ, are nuclear ligand-activated transcription factors that are best known as regulators of glucose and lipid metabolism. PPARα agonists have been shown to have profound anti-inflammatory and antiproliferative effects on human keratinocytes, and are important for maintaining homeostasis of the skin. To better characterize the mechanisms underlying these phenomena, we analysed the effects of PPARα agonists on transforming growth factor (TGF)-α-induced expression of matrix metalloproteinase (MMP)-9. MMP-9 expression in keratinocytes has previously been linked to inflammatory skin diseases, regenerative skin mechanisms, and tumour development and metastasis. We found that PPARα agonists effectively inhibited TGF-α-induced MMP-9 expression in human keratinocytes via a post-transcriptional mechanism, revealing a novel and important aspect of the anti-inflammatory and anticarcinogenic action of these compounds.

Abstract
Acromioclavicular joint dislocations often occur in athletic, young patients after blunt force to the shoulder. Several static and dynamic operative procedures with or without primary ligament replacement have been described. Between February 2003 and March 2009 we treated 313 patients suffering from Rockwood III-V lesions of the AC joint with an AC-hook plate. 225 (72 %) of these patients could be followed up. Mean operation time was 42 minutes in the conventional group and 47 minutes in the minimal invasive group. The postoperative pain on a scale from 1 to 10 (VAS-scale) was rated 2.7 in the conventional group and 2.2 in the minimal invasive group. Taft score showed very good and good results in 189 patients (84%). Constant score showed an average of 92.4 of 100 possible points with 89 % excellent and good results and 11 % satisfying results. All patients had some degree of pain or discomfort with the hook-plate in place. These symptoms were relieved after removal of the plate. The overall complication rate was 10.6 %. There were 6 superficial soft tissue infections, 1 fracture of the acromion, 7 redislocations after removal of the hook-plate. We observed 4 broken hooks which could be removed at the time of plate removal, 4 seromas and 2 cases of lateral clavicle bone infection, which required early removal of the plate. We can conclude that clavicle hook plate is a convenient device for the surgical treatment of Rockwood Grade III-V dislocations, giving good mid-term results with a low overall complication rate compared to the literature. Early functional therapy is possible and can avoid limitations in postoperative shoulder function.

Abstract
AIM Osteitis of the clavicle is rare and not well described in the international literature. We describe a concept of surgical treatment with medium-term observations. METHOD A total of 22 patients (12 women, 10 men; BMI Ø 24.6 kg/m(2), age Ø 48 years) with osteitis of the clavicle were included in the series. The treatment regime consisted of a surgical approach. Data collection was prospective. Data gathered preoperatively and at follow-up included clinical examination, laboratory findings, radiographs and the Constant scoring system. The mean follow-up period was 13.3 (3-53) months. RESULTS The described surgical concept was able to permanently eliminate infection in all cases studied. Surgical revisions were required in six patients. The average Constant score showed a significant increase from 66 to 84 at follow-up. Patients also showed good functional results after total resection of the clavicle. CONCLUSION The reported treatment regime provides reliable results in terms of eliminating infection with good clinical results. Neighboring joints were frequently also involved in the infection and needed to be surgically addressed.

Abstract
Although there is a clear trend toward internal fixation for ankle arthrodesis, there is general consensus that external fixation is required for cases of posttraumatic infection. We retrospectively evaluated the technique and clinical long term results of external fixation in a triangular frame for cases of posttraumatic infection of the ankle. From 1993 to 2006 a consecutive series of 155 patients with an infection of the ankle was included in our study. 133 cases of the advanced "Gächter" stage III and IV were treated with arthrodesis. We treated the patients with a two step treatment plan. After radical debridement and sequestrectomy the malleoli and the joint surfaces were resected. An AO fixator was applied with two Steinmann-nails inserted in the tibia and in the calcaneus and the gap was temporary filled with gentamicin beads as the first step. In the second step we performed an autologous bone graft after a period of four weeks. The case notes were evaluated regarding trauma history, medical complaints, further injuries and illnesses, walking and pain status and occupational issues. Mean age at the index procedure was 49.7 years (18-82), 104 patients were male (67,1%). Follow up examination after mean 4.5 years included a standardised questionnaire and a clinical examination including the criteria of the AO-FAS-Score and radiographs. 92,7% of the cases lead to a stable arthrodesis. In 5 patients the arthrodesis was found partly-stable. In six patients (4,5%) the infection was not controllable during the treatment process. These patients had to be treated with a below knee amputation. The mean AOFAS score at follow up was 63,7 (53-92). Overall there is a high degree of remaining disability. The complication rate and the reduced patient comfort reserve this method mainly for infection. Joint salvage is possible in the majority of cases with an earlier stage I and II infection.

Abstract
Medial clavicle fractures are the least common type of clavicular fractures. Although rare, such injuries deserve rapid diagnosis and effective treatment to avoid future complications. An optimal, standardized operative treatment has not been yet established. We report a case of medial clavicle fracture, where primary operative treatment was indicated due to gross dislocation. An open reduction and osteosynthesis with a modified hook plate was performed, leading to an excellent postoperative outcome after a sixteen-month follow-up. The hook plate seems to be a promising approach for the operative treatment of medial clavicle fractures.

Abstract
AIM The purpose of this study was to evaluate postoperative outcome and functional scores after single bundle anterior cruciate ligament (ACL) reconstruction with the use of quadriceps tendon autografts after a 16 (12-24) month follow-up. METHOD 54 patients (9 women, 45 men, body mass index [BMI] 25.3 [18.1-36.3 kg/m (2)]) were included in this prospective series, treated between January 2004 and December 2005. Ligament stability was assessed with the Lachmann and pivot-shift tests and a KT 1000 arthrometer. Tegner index, Lysholm-Gilquist score and the International Knee Documentation Committee (IKDC) were employed to evaluate the functional outcomes. In addition, the single leg hop test was performed. RESULTS Ligament arthrometry using the KT 1000 arthrometer demonstrated a mean side-to-side difference of 1.53 mm (0.2-4.1 mm). Regarding the Lachmann test, 17 patients (32%) showed 1+ laxity and no patient had an abnormal pivot-shift. The mean Tegner activity score was 4.22 (1-10), the mean Lysholm score was 80.8 (20-100) and the mean IKDC score 68.1 (29-87). Results of the single leg hop test revealed a mean decline of the treated leg to 87.7% (70-100%) of the contralateral side. The mean extension was reduced by 1.7 degrees (0-10 degrees) on the treated knee and the flexion by 2.1 degrees (0-10 degrees), compared to the contralateral knee. CONCLUSION Single bundle anterior cruciate ligament reconstruction using quadriceps tendon demonstrates highly satisfactory results. Due to a moderate donor site morbidity and preservation of the medial stabilizing structures of the knee a wider use in primary cruciate ligament reconstruction may arise in the future.

Abstract
Operative therapy of intraarticular fractures of the calcaneus is an established surgical standard. The aim is an accurate reduction of the fracture with reconstruction of Boehler’s angle, length, axis and subtalar joint surface. Intraoperative 3D-fluoroscopy with the Siremobil Iso-C 3D® mobile C-arm system is a valuable assistant for accurate reconstruction of these anatomical structures. Remaining incongruities can be recognized and corrected intraoperatively. The achieved reduction can be fixed by the advantages of an internal fixator (locked-screw plate interface). In the period of October 2002 until April 2007 we operated 136 patients with intraarticular fractures of the calcaneus by means of anatomical reduction, and internal plate fixator under intraoperative control of 3D-fluoroscopy. All patients were supplied with an orthesis after the operation which allowed weight bearing of 10 kg for 12 weeks for the patients operated between October 2002 and October 2004 (Group A). Transient local osteoporosis was observed in all X-Rays at follow-up after an average of 8,6 months. Therefore we changed our postoperative treatment plan for the patients operated between November 2004 and April 2007 (Group B). Weight bearing started with 20 KG after 6 weeks, was increased to 40 KG after 8 weeks and full weight bearing was allowed after 10 weeks for these patients. In no case a secondary dislocation of the fracture was seen. No bone graft was used. At follow up the average American Foot and Ankle Society Score (AOFAS) were 81 for Group_A, compared to 84 for Group B, treated with earlier weight bearing. Autologous bone graft was not necessary even if weight bearing was started after a period of six weeks postoperatively. The combination of 3D-fluoroscopy with locked internal fixation showed promising results. If the rate of patients developing subtalar arthrosis will decrease by this management will have to be shown in long term follow up.

Abstract
BACKGROUND The aim of this study was to compare safety and efficacy of catheter-mediated femoral nerve block analgesia with systemic pain therapy in patients with proximal femoral fractures in the pre-operative and post-operative setting using a protocol for coordinating pain management. METHODS In a prospective randomised trial of patients attending the emergency department, 100 individuals were selected with a clinically diagnosed proximal femoral fracture. Patients were divided into two equal groups A and B. Group A (n=50) received a catheter-mediated femoral nerve block with 1% prilocaine (40 ml) and post-operatively 0.2% ropivacaine (30 ml) 6 hourly. Group B (n=50) initially received intravenous metamizol (1 g) and a fixed combination of oral tilidine (100 mg) + naloxone (8 mg). Patients aged 90 years or more received a reduced dose (tilidine 75 mg + naloxone 6 mg). In the post-operative period regular oral ibuprofen (400 mg, 8 hourly) in addition to oral tilidine (50 mg) + naloxone (4 mg) was given as required for break through pain. Pain intensity was measured using a verbal rating scale (VRS) from 1 to 5: pain free (=1), mild pain (=2), moderate pain (=3), severe pain (=4), excruciating pain (=5). Pain scores were recorded at rest (R), during passive anteflection (30 degrees) of the hip (PA) on arrival and at 15 and 30 min after initial administration of analgesia. Thereafter, recordings were made 4 times a day up to the third post-operative day. RESULTS Pain scores were comparable for both groups on admission (VRS in R 2.50 vs. 2.46; VRS during PA 4.30 vs. 4.34). Significant pain relief was achieved in both groups following initial administration of analgesia, but the total pain scores in group A were significantly lower than in group B (VRS in R 1.22 vs. 1.58, p<0.01 and VRS during PA 2.66 vs. 3.26; p<0.001). No difference was noted between the two groups during the first 3 post-operative days. No severe complications occurred as a result of analgesia, however, the catheter was dislodged in 20% of patients in group A resulting in the need for systemically administered analgesia. CONCLUSION All patients presenting with proximal femoral fractures should receive adequate analgesia within the emergency department even prior to radiographic imaging. Femoral nerve block should be considered as the method of choice. The insertion of a femoral nerve block catheter has the dual advantage of early analgesia permitting repeated clinical examination in addition to continued post-operative pain management. The cumbersome logistics inherent in this technique within the clinical setting limits its practical application. An initial single-shot regional nerve block followed by a systemic post-operative analgesia protocol was considered an appropriate alternative. The execution of safe, consistent and appropriate regional nerve block anaesthesia is reliant on formal guidelines and protocols as agreed by the multidisciplinary teams involved with patient-directed pain management and good clinical practice.

Abstract
Fractures of the humeral head account for 5% of all fractures and incidence increases with age. Depending on fracture form and patients age a wide variety of therapeutical options exist. Stable fractures can be treated conservatively, while the majority of unstable and displaced fractures require surgical treatment. Many different surgical options are available; open reduction and internal fixation are widely preferred. The S3 Proximal Humerus Plate is a contoured plate to match the complex shape of the proximal humerus. It is designed to be positioned distal to the greater tuberosity preventing subacromial impingement. Between august 1 and 30, 2007, 5 patients meeting the inclusion criteria (that is primary operative stabilization within 7 days after trauma in a standardized way and minimal follow up period of 3 month) with acute fractures of the proximal humerus were treated with S3 Proximal Humerus Plate. Follow up was performed using the Constant Score. The mean age was 59.0 years. According to the Neer classification fractures were rated as Neer 2,3 and 4. A mean Constant score of 72.3 (57-86) points was obtained. We did not observe any complications like humeral head necroses, loss of reduction, deep infection or breakage of the plate.

Abstract
Botryomycosis is a rare chronic bacterial infection, which can involve the skin as well as internal organs. Clinically and histologically it resembles actinomycosis and deep fungal infections. The most common causative organisms described are Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, but the pathogenesis of botryomycosis is still poorly understood. A 16-year-old girl presented with multiple erythematous solid and partly purulent nodules which were extremely resistant to therapy. In this case we could diagnose a botryomycosis caused by Staphylococcus aureus.

Abstract
Sodium thiosulphate has been used in medicine for almost 100 years. There are some very important areas of application such as cyanide intoxications or the treatment of cisplatin toxicity. Till this day, this compound is almost unknown to most physicians. This is astonishing, especially because there are some promising reports in the literature describing a possibly wider area of application in different domains of medicine such as urology, nephrology or dermatology. Perhaps one of the most exciting and recent domains of sodium thiosulphate use is the treatment of calciphylaxis, providing new options dealing with this severe and mostly lethal illness. The goal of this article is to review the new application possibility of this compound.

Abstract
In times of plentiful nutrition an environmental advantage turns into a problem - obesity. Apart from an increase in morbidity and overall mortality the development of osteoarthrosis is well documented. Pre-arthrotic conditions may arise from trauma and can lead, depending on the pattern of injury, to full-blown arthrosis. The presence of obesity can play the role of a relevant progressive factor in this setting. Here we report about the case of an obese man (BMI 53.5 kg/m(2)), who suffered a fracture of the femoral head with acetabular participation (Pipkin IV) as well as a fracture of the tibial plateau. Operative management and rehabilitation were followed by gastric bypass surgery for weight reduction. The case is discussed with regard to the present literature.
