Burns in the elderly: a nationwide study on management and clinical outcomes.

BACKGROUND: In modern-day burn care, advanced age remains an important predictor for mortality among burn victims. In this study, we compared the complete treatment trajectory (including pre-hospital and surgical treatment) and the outcomes between an elderly burn population and a younger adult burn population. METHODS: In this nationwide study, data from the Dutch Burn Repository were used. This is a uniform national registration for Dutch specialized burn care. All adult patients that were admitted to one of the three Dutch burn centres from the period 2009 to 2015 were included in the analysis. Burn patients were considered as elderly when ≥65 years of age, and were then further subdivided into three age categories: 65-74, 75-85 and 85+ years. Younger adults in the age category 18-64 years were used as the reference group.Surgical management was studied comprehensively and included timing of surgery, the number of procedures and details on the surgical technique, especially the technique used for debridement and the grafting technique that was applied.For the comparison of clinical outcome, the following parameters were included: mortality, wound infections, length of stay/TBSA (total body surface area) burned, discharge disposition and secondary reconstructions. RESULTS: During the study period, 3155 adult patients were included (elderly, n = 505). Burn severity, reflected by the median TBSA, varied between 3.2-4.0% and was comparable, but aetiology and pre-hospital care were different between elderly and the younger adult reference group.Surgical treatment was initiated significantly faster in elderly burn patients (p < 0.001). Less selective techniques for surgical debridement were used in the elderly burns patients (hydrosurgery, 42.0% vs 23.5-22.6%), and on the other hand more avulsion (5.3% vs 7.3-17.6%) and primary wound closure (6.7% vs 24.5%). The most frequently used grafting technique was meshed skin grafts (79.2-88.6%); this was not related to age.Mortality increased rapidly with a higher age and showed a high peak in the 85+ category (23.8%). Furthermore, considerable differences were found in hospital discharge disposition between the elderly and the reference group. CONCLUSIONS: In conclusion, elderly burn patients who require specialized burn care are vulnerable and medically challenging. Differences in aetiology, comorbidity, physiology and the management prior to admission possibly affect the initial surgical management and result in significantly worse outcomes in elderly. Elderly patients need optimal, timely and specialized burn care to enhance survival after burn injuries.

[Carbapenem-resistant bacteria transferred to the Netherlands: patients colonised during hospitalisation in Romania]. / Carbapenemresistente bacteriën overgebracht naar Nederland.

Three patients were recently transferred to two Intensive Care Units (ICUs) in the Netherlands from two different ICUs in Bucharest, Romania. The patients appeared to be colonised with several, partly identical, carbapenemase-producing bacteria (CPB) after a short hospitalisation in Romania. In this article, we show that it is important to be aware of the possibility that patients are colonised with CPB after a short hospitalisation abroad. This has consequences for infection prevention measurements, but probably also for the discontinuation of selective bowel decontamination in the ICU.

Red Blood Cell Distribution Width and the Platelet Count in Iron-deficient Children Aged 0.5-3 Years.

Early detection of iron deficiency (ID) and iron deficiency anemia (IDA) in young children is important to prevent impaired neurodevelopment. Unfortunately, many biomarkers of ID are influenced by infection, thus limiting their usefulness. The aim of this study was to investigate the value of red blood cell distribution width (RDW) and the platelet count for detecting ID(A) among otherwise healthy children. A multicenter prospective observational study was conducted in the Netherlands to investigate the prevalence of ID(A) in 400 healthy children aged 0.5-3 years. ID was defined as serum ferritin (SF) <12 µg/L in the absence of infection (C-reactive protein [CRP] <5 mg/L) and IDA as hemoglobin <110 g/L combined with ID. RDW (%) and the platelet count were determined in the complete blood cell count. RDW was inversely correlated with SF and not associated with CRP. Calculated cutoff values for RDW to detect ID and IDA gave a relatively low sensitivity (53.1% and 57.1%, respectively) and specificity (64.7% and 69.9%, respectively). Anemic children with a RDW >14.3% had a 2.7 higher odds (95% confidence interval [CI]: 1.2-6.3) to be iron deficient, compared with anemic children with a RDW <14.3%. The platelet count showed a large range in both ID and non-ID children. In conclusion, RDW can be helpful for identifying ID as the cause of anemia in 0.5- to 3-year-old children, but not as primary biomarker of ID(A). RDW values are not influenced by the presence of infection. There appears to be no role for the platelet count in diagnosing ID(A) in this group of children.

The value of Ret-Hb and sTfR in the diagnosis of iron depletion in healthy, young children.

OBJECTIVES: Reticulocyte hemoglobin (Ret-Hb) content and soluble transferrin receptor (sTfR) are described as promising biomarkers in the analysis of iron status. However, the value of Ret-Hb and sTfR in the early detection of iron depletion, as frequently observed in children in high-income countries, is unclear. We hypothesized that young children to iron depletion, using the WHO cutoff of ferritin <12 µg/l, would have lower Ret-Hb and higher sTfR concentrations compared to children with a ferritin ⩾level 12 µg/l. SUBJECTS/METHODS: In this cross-sectional study, we analyzed mean concentrations of Ret-Hb and sTfR in 351 healthy children aged 0.5-3 years in a high-income country. The Student's t-test was used to compare Ret-Hb and sTfR concentrations between groups. RESULTS: We showed that concentrations of Ret-Hb and sTfR are similar in children with and without iron depletion. A decrease in Ret-Hb concentration was present only when ferritin concentrations were <8 µg/l. sTfR concentrations were similar in children with ferritin concentrations <6 µg/l and ⩾12 µg/l. CONCLUSIONS: Our results showed that the discriminative value of Ret-Hb and sTfR for the detection of iron depletion is limited. Our findings suggest that ferritin is the most useful biomarker in the screening of iron depletion in healthy children in high-income countries. However, ideally, reference ranges of iron status biomarkers should be based on studies showing that children with concentrations outside reference ranges have poor neurodevelopmental outcomes.

The influences of factors associated with decreased iron supply to the fetus during pregnancy on iron status in healthy children aged 0.5 to 3 years.

OBJECTIVE: To investigate whether maternal anemia, pregnancy-induced diabetes, hypertension and smoking contributed to the recently found high prevalence of iron deficiency in a population of otherwise healthy children. STUDY DESIGN: Iron status was assessed in 400 children aged 0.5 to 3 years. We obtained information on the mothers' laboratory results, the presence of diabetes and hypertension, smoking habits and use of medication while pregnant. RESULT: We found no influence of maternal anemia, diabetes, hypertension or smoking during pregnancy on iron status in the children. Mean corpuscular volume (MCV) values of the children were positively correlated to maternal MCV values. CONCLUSION: In this population, iron status in children is not affected by maternal anemia or maternal factors that are associated with a decreased iron transport during pregnancy. The correlation between MCV values in mothers and their children might be explained by genetic and/or shared environmental factors.

Dermal substitution in acute burns and reconstructive surgery: a subjective and objective long-term follow-up.

Tissue engineering and dermal substitution are currently prominent topics of wound-healing research. However, no extensive clinical trials with objective evaluation criteria have been published so far that support the clinical effectiveness of dermal equivalents in the long term. The dermal substitute that is discussed here is derived from bovine collagen and elastin-hydrolysate and has been shown to improve skin elasticity during a short-term clinical follow-up of scar reconstructions. In this study we will present the long-term outcome by means of objective and subjective scar assessment tools for dermal substitution in acute burn wounds and scar reconstructions. In a clinical trial, an intraindividual comparison was performed between the conventional split-thickness autograft and a combination of the collagen/elastin substitute with an autograft. After 1 year, scars were evaluated by the Cutometer SEM 474 for objective elasticity measurements and by planimetry to establish scar contraction. An independent observer subjected scars to a generally accepted clinical scar assessment tool: the Vancouver Scar Scale. In addition, patients gave their impression of the outcome. Forty-two paired burn wounds and 44 paired scar reconstructions were included and evaluated 1 year after surgery. Although substituted scar reconstructions demonstrated an elasticity improvement of approximately 20 percent compared with control wounds, no statistically significant differences were found for skin elasticity, scar contraction, Vancouver Scar Scale, and patient's impression in both categories after 1 year. An extensive long-term follow-up shows that the dermal substitute, which was proven effective in a clinical trial on a short-term basis, did not yield statistical evidence for a long-term clinical effectiveness of dermal substitution.

Graft survival and effectiveness of dermal substitution in burns and reconstructive surgery in a one-stage grafting model.

Survival of the autograft and objective parameters for scar elasticity were evaluated after dermal substitution for acute burns and reconstructive surgery. The dermal substitute, which was based on bovine type I collagen and elastin-hydrolysate, was evaluated by intraindividual comparison in a clinical trial. The substitute was applied in a one-step procedure in combination with a split-thickness autograft. This treatment was compared with the conventional treatment, the split-thickness antograft. After 1 week, the percentage of autograft survival was assessed. The Cutometer SEM 474 was used to obtain objective measurements of skin elasticity parameters 3 to 4 months postoperatively. Forty-two pairs of wounds (31 patients, age 32.9 +/- 19.3 years; burned surface area, 19.8 +/- 14.5 percent) were treated because of acute burns. Reconstructive surgery was performed on 44 pairs of wounds (31 patients, age 33.9 +/- 17.5 years). Autograft survival was not altered by the substitute for reconstructive wounds, although a slight but significant reduction (p = 0.015) was established in the burn category for substituted compared with nonsubstituted wounds. However, the necessity for regrafting was not increased by substitution. Cutometer measurements of reconstructive wounds with a dermal substitute demonstrated a significant increase of pliability (50 percent, p < 0.001), elasticity (defined as immediate extension, 33 percent, p = 0.04), maximal extension (33 percent, p = 0.002), and immediate retraction (31 percent, p = 0.01), as compared with nonsubstituted wounds. After burn surgery, no improvement was found for the different elasticity parameters. Dermal substitution in a one-stage grafting model seems feasible with respect to graft survival. Skin elasticity was considerably improved by the collagen/elastin dermal substitute after reconstructive surgery.
