Three-dimensional imaging: a novel, valid, and reliable technique for measuring wound surface area.

PURPOSE: The aim of this study was to investigate the validity and reliability of a novel three-dimensional imaging technique using Artec MHT™ 3D Scanner for measuring the wound surface area. METHODS: The validity was tested by measuring the surface area of 60 stickers (gold standard) on 20 volunteers. Stickers with standardized areas of 2590, 7875, and 15,540 mm2 were applied on the thorax, forearm, and thigh, respectively. For the reliability test, 58 burn wounds on 48 patients were assessed twice by two different observers with the Artec MHT™ 3D Scanner. Scanning, post-processing, and surface area measurements were performed by two clinicians. RESULTS: The results for the validity analysis showed an intraclass correlation coefficient of 0.99 and coefficient of variation of the thorax, forearm, and thigh were 1.1%, 0.9%, and 0.6%, respectively. The reliability analysis showed an intraclass correlation coefficient of 0.99, a coefficient of variation of 6.3%, and limits of agreement between measurements of two observers were calculated at 0 ± 0.17 × mean surface area. CONCLUSION: Three-dimensional imaging using the Artec MHT™ 3D Scanner is a valid and reliable method for measuring the wound surface area.

Photographic assessment of burn size and depth: reliability and validity.

OBJECTIVE: The aim of this study was to examine the reliability and validity of using photographs of burns to assess both burn size and depth. METHOD: Fifty randomly selected photographs taken on day 0-1 post burn were assessed by seven burn experts and eight referring physicians. Inter-rater reliability in both groups (experts vs. referrers) was calculated. The validity of burn size assessment was calculated using live assessment as the gold standard, and of burn depth using clinical assessment in combination with laser Doppler imaging as the gold standard. The validity of the photographically-assessed indication for surgery was calculated using laser Doppler imaging and actual treatment as the gold standard. Finally, agreement in referral indication was calculated. RESULTS: Using photographs, burn size could be assessed reliably and validly by experts (ICCs of 0.83 and 0.87), but not by referrers (ICCs of 0.68 and 0.78). Photographic assessment of burn depth was neither reliable nor valid, with ICCs respectively of 0.38 and 0.28 for experts and 0.24 and 0.13 for referrers. The indication for surgery could also not be assessed validly. Agreement between assessors regarding referral indication was low. CONCLUSION: Burn size, but not burn depth, can be assessed reliably and validly by experts using photographs of the burn wound. We recommend exploring other forms of telemedicine, like live interactive video, to investigate whether this leads to an improved burn depth assessment where clinical assessment is not possible.

Frostbite injury: a paragliding accident at 5500 meters.

Frostbite as a result of mountaineering or arctic expeditions is a well-known problem. In this article a rare case of frostbite injury following a paragliding accident at high altitude is described. A cumulonimbus cloud formation drifted the patient up with a high velocity to approximately 5500 m. He acquired frostbite injuries of the neck, wrists, hands and left leg, affecting 5% of the total body surface area. The frostbite was initially treated by rewarming, with later debridement and local application of silver sulfadiazine and povidone-iodine dressings. Within three months all the injuries were healed.

Management and outcome of burn injuries during pregnancy: A systematic review and presentation of a comprehensive guideline.

Pregnant women are a vulnerable subgroup of burn patients, due to altered physiological state and possible adverse effect on the fetus. The aim of this study was to develop a guideline for a tailored treatment of pregnant patients with burns to optimally treat both mother and fetus. This study consists of two parts: the first part contains a systematic review that presents a comprehensive overview of the literature on the management and outcome of pregnant women who sustain severe burn injuries and based on the results of this review, a guideline on the general, obstetric and burn management was developed and presented in the second part. A total of 35 studies including 1395 patients were included. Although the clinical outcomes seemed to be similar to non-pregnant patients, one study showed that mortality might be higher in the pregnant population. Predictive factors for maternal and fetal mortality were a total burned surface area of over 40% and inhalation injury. Early surgery may lead to a higher chance of survival of mother and fetus. A comprehensive guideline on the general management of pregnant patients with burns, obstetric management and specific burn management is provided. We encourage international burn organizations and guideline committees to use and evaluate the presented guideline.

Doxepin cream is not effective in reducing itch in burn scar patients: A multicenter triple-blind randomized clinical crossover trial.

OBJECTIVE: To evaluate the effect of doxepin hydrochloride 5% cream on reducing pruritus in burn scar patients compared to a placebo cream. METHOD: We conducted a multicenter triple-blind randomized clinical placebo-controlled crossover trial in which burn patients ≥18 years with an itch intensity ≥3 on a Visual Analogue Scale (VAS) were randomized between a doxepin-placebo or placebo-doxepin treatment protocol. Patients used each cream during two weeks with a wash-out period of one week in between. Primary outcome was change in itch intensity in two weeks' time using the VAS. Secondary outcome included the impact of itch (Burn Itch Questionnaire). Other parameters were the use of hydrating cream, silicon treatment, pressure garments, and other antipruritic medication. RESULTS: Twenty-seven patients were included. The change in itch intensity (VAS) was not different during the doxepin and placebo period (p=0.994); neither the doxepin cream nor placebo cream reduced itch intensity. However, based on the Burn Itch Questionnaire, we observed a statistically significant decrease in itch intensity and improvement in impact scores in both treatment groups, but no difference in the degree of reduction between the groups. CONCLUSION: Doxepin cream was not effective in reducing pruritus in our burn patient study population.

A rare complication after laparoscopic gastric banding: connecting-tube penetration into the hilus of the kidney.

Laparoscopic adjustable gastric banding is a common operation for morbid obesity. Late complications mainly originate from either the injection port (dislocation, infection, leakage) or the gastric band (pouch dilatation, slippage, leakage, gastric erosion). Complications from the tube, connecting the port with the band, are rarely described. We report the penetration of a loose connecting tube into the kidney 8 months after removal of an infected injection port.

A systematic review on surgical and nonsurgical debridement techniques of burn wounds.

OBJECTIVE: To provide a complete overview of all burn debridement techniques studied in recent literature and to find the best evidence with regard to efficiency and safety. METHOD: A systematic review was performed. Searches were conducted in electronic databases such as PubMed, Embase, Cochrane, CINAHL, Web of Science, and Academic Search Premier. All studies published from 1990 onwards, on the efficiency and/or safety of burn debridement techniques in patients with thermal burn injuries of any age, were included. Primary outcomes were time to complete wound healing and time to complete debridement. Randomized trials were critically appraised. RESULTS: Twenty-seven studies, including four randomized clinical trials, were included. Time to wound healing in the conventional tangential excision (seven studies), hydrosurgery (eight studies), enzymatic debridement (eleven studies), and shock waves group (one study) ranged from 13-30, 11-13, 19-33, and 16 days, respectively. Time to complete debridement ranged from 5-10, 4-23, and 1-9 days, respectively. Furthermore, secondary outcomes (including grafting, mortality, and scar quality) were compared between the debridement categories. CONCLUSION: Convincing evidence in favor of any of these techniques is currently lacking. Future studies regarding (new) debridement techniques need to use standardized and validated outcome measurement tools to allow improved standardization and comparisons across studies.

Patterns and predictors of burn scar outcome in the first 12 months after burn: The patient's perspective.

OBJECTIVE: This study aimed to provide insight into the patterns and factors that predict burn scar outcomes at 3, 6 and 12 months after burn. METHODS: The Patient and Observer Scar Assessment Scale (POSAS) was used to assess the scar formation of each patient. Structural equation modelling was used. The predictor variables used in this study were sex, three age categories, TBSA, depth of the wound and cause of the burn. RESULTS: The POSAS patient total and individual item scores demonstrated a statistically significant decrease in the first 12 months after burn, except for the relief item. Male patients had a lower total and items scores (better scar quality) for pain and pruritus compared with female patients. Full thickness burns had a higher scores for pruritus, pliability, thickness and relief compared to the partial-thickness burns. Ages younger than 5 years, higher TBSA values and flame burns were predictors of various POSAS items at 3 and 6 months after burn. CONCLUSION: The POSAS patient total and individual item scores demonstrated a statistically significant improvement in the scar quality in the first 12 months after burn, except for the relief. Sex, age, depth of the wound, the percentage of TBSA and flame burns were predictors of various POSAS patient items at 3, 6 and 12 months after burn.

Three-dimensional imaging is a novel and reliable technique to measure total body surface area.

OBJECTIVE: The aim of this study was to explore the diverse clinimetric aspects of three-dimensional imaging measurements of TBSA in clinical practice compared with the methods currently used in clinical practice (i.e., the rule of nines and palm method) to measure TBSA in clinical practice. METHOD: To assess reliability, two independent researchers measured the TBSAs of 48 burn patients using Artec MHT™ Scanner and software. Subsequently, a resident and burn specialist estimated the TBSA of the same wounds using the rule of nines and palm method. RESULTS: Three-dimensional imaging showed excellent inter-observer reliability, with an intra-class correlation coefficient (ICC) of 0.99, standard error of measurement (SEM) of 0.054, and limits of agreement (LoA) of ±0.15×the mean TBSA (between the measurements of two researchers). The inter-observer reliability of the methods used in current clinical practice was less reliable, with an ICC of 0.91, SEM of 0.300 and LoA of ±0.78×the mean TBSA. The inter-observer reliability was least reliable between three-dimensional imaging and the residents compared with the burn specialists for the estimated TBSA, with an ICC of 0.68, SEM of 0.69 and LoA of ±1.49×the mean TBSA. CONCLUSION: The inter-observer reliability of three-dimensional imaging was superior compared with the rule of nines and palm method.

Can vitamin C prevent complex regional pain syndrome in patients with wrist fractures? A randomized, controlled, multicenter dose-response study.

BACKGROUND: Complex regional pain syndrome type I is treated symptomatically. A protective effect of vitamin C (ascorbic acid) has been reported previously. A dose-response study was designed to evaluate its effect in patients with wrist fractures. METHODS: In a double-blind, prospective, multicenter trial, 416 patients with 427 wrist fractures were randomly allocated to treatment with placebo or treatment with 200, 500, or 1500 mg of vitamin C daily for fifty days. The effect of gender, age, fracture type, and cast-related complaints on the occurrence of complex regional pain syndrome was analyzed. RESULTS: Three hundred and seventeen patients with 328 fractures were randomized to receive vitamin C, and ninety-nine patients with ninety-nine fractures were randomized to receive a placebo. The prevalence of complex regional pain syndrome was 2.4% (eight of 328) in the vitamin C group and 10.1% (ten of ninety-nine) in the placebo group (p=0.002); all of the affected patients were elderly women. Analysis of the different doses of vitamin C showed that the prevalence of complex regional pain syndrome was 4.2% (four of ninety-six) in the 200-mg group (relative risk, 0.41; 95% confidence interval, 0.13 to 1.27), 1.8% (two of 114) in the 500-mg group (relative risk, 0.17; 95% confidence interval, 0.04 to 0.77), and 1.7% (two of 118) in the 1500-mg group (relative risk, 0.17; 95% confidence interval, 0.04 to 0.75). Early cast-related complaints predicted the development of complex regional pain syndrome (relative risk, 5.35; 95% confidence interval, 2.13 to 13.42). CONCLUSIONS: Vitamin C reduces the prevalence of complex regional pain syndrome after wrist fractures. A daily dose of 500 mg for fifty days is recommended.

[Ten tips for initial assessment and treatment of minor burns]. / Eerste beoordeling en behandeling van kleine brandwonden: 10 tips.

The initial care of a patient with burns is a challenge for every doctor. After cooling the burn appropriately, a careful history and a good initial assessment are of essential importance for treatment. The burn should be inspected regularly for early detection of any infection and to evaluate wound healing. If healing has not occurred in two weeks, hypertrophic scarring may develop and surgical treatment should be considered. It is always possible to contact the burns centres in Beverwijk, Rotterdam and Groningen to discuss treatment of the burn, any infection of a wound, consideration of surgical treatment, or transfer of a patient to a burn centre.

Usability and effectiveness of Suprathel® in partial thickness burns in children.

PURPOSE: Evaluation of usability and effectiveness of Suprathel® in the treatment of partial thickness burns in children. METHODS: A prospective, observational study to evaluate adherence of Suprathel® to the wound bed, reepithelialization time, grafting, wound colonization and infection, pain, dressing changes, length of hospital stay (LOS) and scar formation. RESULTS: Twenty-one children (median age 2.4 years, range 5 months-14 years) with a median total body surface area (TBSA) of 4 % (range 1-18) were included. Median LOS was 10 days (range 3-20). Median outer layer dressing changes was 3 (range 1-14). Suprathel® was only adherent in wounds debrided with Versajet®. Median reepithelialization time was 13 days (range 7-29). Three patients needed a split skin graft. There were 7 (33 %) patients with wound colonization before application of Suprathel®. This increased to 12 (57 %) patients during treatment. One patient developed a wound infection. Median visual analog scale (VAS) scores for background and procedural pain in patients >7 years were 3.2 (range 2-5) and 3.5 (range 2-5), respectively. In younger patients, median background and procedural COMFORT-B scores were 13.8 (range 10-23) and 14.8 (range 13-23, p = 0.03), respectively. Patient and Observer Scar Assessment Scale (POSAS) scores were favorable after 3 and 6 months post burn. CONCLUSIONS: Suprathel® provides potential advantages regarding pain and scar formation, but extensive wound debridement is needed to achieve adequate adherence.

Reconstruction plates for midshaft clavicular fractures: A retrospective cohort study.

BACKGROUND: For the fixation of displaced midshaft clavicular fractures different plates are available, each with its specific pros and cons. The ideal plating choice for this lesion remains subject to ongoing discussion. Reconstruction plates are cheap and easily bendable, but their strength and stability have been questioned. The aim of this study was to evaluate the failure rate of reconstruction plates in the fixation of clavicular fractures. MATERIALS AND METHODS: A multicenter, retrospective cohort study of all consecutive patients with a displaced, midshaft clavicular fracture (Robinson type 2a/2b) treated with a 3.5-mm reconstruction plate between 2006 and 2013 were evaluated. The primary outcome measure was reoperation rate due to implant failure. Secondary outcome measures were nonunion, symptomatic malunion and elective plate removal. RESULTS: One hundred and eleven patients were analyzed. During a median follow-up of 8 months, 14 patients (12.6%) had implant failure, of which 7 (6.3%) required a reoperation. Three nonunions (2.7%) and no symptomatic malunions occurred. Plate removal was indicated in 37.8% of patients because of implant irritation. DISCUSSION: The incidence of reoperation due to implant failure following clavicular plate fixation with a reconstruction plate is 6.3%. Although comparison with other plate types is difficult since rates in literature vary greatly, reoperation rates in other plates are reported around 2-3%, suggesting that reconstruction plates have a higher incidence of implant failure warranting reoperation. Therefore, especially in patients with known risk factors for complications (e.g. smoking, osteoporosis, comminuted fractures), a stronger plate than a reconstruction plate should be considered. LEVEL OF EVIDENCE: Level IV. Retrospective study.

Evaluation of saline, RPMI and DMEM/F12 for storage of split-thickness skin grafts.

Skin grafting is standard of care for severe burn and trauma patients. Graft sites are often accompanied with more pain than the burn sites. To minimize graft site areas, excess skin remaining after harvesting, is stored in saline at 4°C to be used for transplantation up to 1 week later. However, the optimal storage solution and maximum storage time are not known. We set out to determine the storage time after which stored skin is still viable. In addition, different storage solutions were tested. Split-thickness skin from 15 donors with a thickness of 0.3 mm was stored in normal saline, in medium, RPMI or DMEM/F12, allowing pairwise comparison. Biopsies were taken up to 3 weeks for histology and for skin viability assessment using an MTT based activity assay. Activity of the saline stored control decreased to 62% at day 7 and to 27% at day 14. Activity was retained at a higher level in RPMI and was 78% at day 7 and 70% at day 14. Results with DMEM/F12 showed a similar trend as the saline control. Based on activity, RPMI was found to be superior to DMEM/F12 (on days 3 and 10) and both saline and DMEM/F12 (on days 14 and 21). Capability to proliferate (BrdU incorporation) did not differ between media, up to 7 days. Histologically, the number of apoptotic cells increased in time but differences between media were not noted. Based on these results, RPMI would be an improvement over saline in retaining viability of skin grafts during storage, and possibly in improved take rate.

Pain experience and functional outcome of inpatient versus outpatient anterior cruciate ligament reconstruction, an equivalence randomized controlled trial with 12 months follow-up.

BACKGROUND: Arthroscopic reconstruction of the anterior cruciate ligament (ACL) has traditionally been performed in an inpatient setting. Outpatient treatment may offer the advantages of cost reduction and higher patient satisfaction. HYPOTHESIS/PURPOSE: We investigated whether ACL reconstruction in an outpatient setting is equally safe as in an inpatient setting and whether comparable functional outcomes can be achieved. We hypothesized that the outcomes of outpatient ACL reconstruction result in similar outcomes as inpatient ACL reconstruction. STUDY DESIGN: A prospective randomized controlled trial was conducted at one centre. METHODS: Forty-six patients were randomized to outpatient treatment or a 2-day admission after ACL reconstruction. The functional outcome was evaluated with the Lysholm, Tegner and International Knee Documentation Committee scores. Safety of the procedures was judged according to pain experience and readmission rate. The duration of follow-up was 1 year after ACL reconstruction. The patients were provided with a simple postoperative analgesic protocol. The linear mixed effect model for repeated measures was used for testing the differences between the study groups. RESULTS: No significant differences were found between the study groups in all the outcome measures. No readmissions were recorded related to pain. One complication was recorded in the outpatient group versus three in the inpatient group. CONCLUSION: This study indicates that outpatient care after ACL reconstruction yields comparable functional results and postoperative pain experience as inpatient care and is a safe option. A simple analgesic protocol provides adequate pain relief during the postoperative phase. LEVEL OF EVIDENCE: I.

[Bariatric surgery using an adjustable gastric band for morbid obesity: initial 30 patients in The Netherlands]. / Bariatrische chirurgie met een variabele maagband voor morbide obesitas: eerste 30 patiënten in Nederland.

OBJECTIVE: Early evaluation of efficacy and safety of Adjustable Silicone Gastric Banding (ASGB) in the treatment of morbid obesity. DESIGN: Descriptive. SETTING: Red Cross Hospital, Beverwijk, the Netherlands. METHOD: In the period September 1991-September 1993, 30 eligible patients (5 men and 25 women, median age 37 years (range 22-60), median excessive weight 63 kg (18-94), median body mass index (BMI) 43 kg/m2 (28-53)) were operated. A horizontal gastroplasty was performed resulting in a pouch of 25 ml and a new stomach outlet with a diameter of 12 mm. The volume of the band may be increased in order to diminish the diameter of the outlet according to clinical needs postoperatively. RESULTS: The follow-up was 10 months in 13 of the 30 patients. After 6 months median BMI was 33 kg/m2 (23-38) and median loss of excessive weight 53% (27-94), after 10 months these 28 kg/m2 (23-38) and 67% (27-98) respectively. No patients died perioperatively; 52 gastric band adjustments were necessary in 17 patients. Complications consisted of: band dislocation (1 patient), functional stenosis (2), gastric perforation (2) and wound infection (1). Four patients needed reoperation. CONCLUSION: In this short term follow-up ASGB gave a good weight reduction. Advantages of ASGB are the reversibility of the operation and the adjustable outlet.

The evaluation of nasal mupirocin to prevent Staphylococcus aureus burn wound colonization in routine clinical practice.

BACKGROUND: Staphylococcus aureus wound colonization frequently occurs in patients with burns and can cause impaired wound healing. Nasal mupirocin application may contribute to the reduction of burn wound colonization of endogenous origin, whereas colonization by the exogenous route can be reduced by blocking cross-infection from other sources. In this study we evaluated whether the implementation of routine treatment of patients and burn center personnel using nasal mupirocin ointment reduces S. aureus burn wound colonization. METHODS: We composed three study groups, consisting of a control period (Control), a mupirocin period (MUP), in which patients with burns were all receiving nasal mupirocin at admission, and a mupirocin+personnel period (MUP+P), in which we also screened the burn center personnel and decolonized S. aureus carriers by nasal mupirocin. RESULTS: The patients who carried S. aureus in their nose and did not have S. aureus burn wound colonization at admission were considered as patients susceptible for the use of nasal mupirocin. In these patients, the S. aureus burn wound colonization rate was the same in all study groups. S. aureus nasal carriage was a significant independent risk factor for burn wound colonization (OR: 3.3; 95% CI: 1.4-7.6) when analyzed within the three study groups. CONCLUSION: Although S. aureus carriage is a significant risk factor for developing burn wound colonization, the routine use of nasal mupirocin did not contribute to a reduction of burn wound colonization.

Epidemiology and trends in severe burns in the Netherlands.

INTRODUCTION: The aim of this study was to characterize the epidemiology of severe burns in the Netherlands, including trends in burn centre admissions, non burn centre admissions and differences by age. METHODS: Patients with burn-related primary admission in a Dutch centre from 1995 to 2011 were included. Nationwide prospectively collected data were used from three separate historical databases and the uniform Dutch Burn Repository R3 (2009 onwards). General hospital data were derived from the National Hospital Discharge Register. Age and gender-adjusted rates were calculated by direct standardization, using the 2005 population as the reference standard. RESULTS: The annual number of admitted patients increased from 430 in 1995 to 747 in 2011, incidence rates increased from 2.72 to 4.66 per 100,000. Incidence rates were high in young children, aged 0-4 years and doubled from 10.26 to 22.96 per 100,000. Incidence rates in persons from 5 up to 59 increased as well, in older adults (60 years and older) admission rates were stable. Overall burn centre mortality rate was 4.1%, and significantly decreased over time. There was a trend towards admissions of less extensive burns, median total burned surface area (TBSA) decreased from 8% to 4%. Length of stay and length of stay per percent TBSA decreased over time as well. CONCLUSIONS: Data on 9031 patients admitted in a 17-year period showed an increasing incidence rate of burn-related burn centre admissions, with a decreasing TBSA and decreasing in-burn centre mortality. These data are important for prevention and establishment of required burn care capacity.

Methylated spirit burns: an ongoing problem.

OBJECTIVE: Despite many educational campaigns we still see burns caused by methylated spirit every year. We undertook a retrospective study to analyse the impact of this problem. METHODS: We retrospectively collected data of all patients with burns caused by methylated spirit over twelve years from 1996 to 2008. Our main endpoints were: incidence, age, mechanism of injury, total body surface area (TBSA) burned, burn depth, need for surgery and length of hospital stay. RESULTS: Ninety-seven patients with methylated spirit burns were included. During the study period there was no decrease in the number of patients annually admitted to the burn unit with methylated spirit burns. 28% of the patients (n=27) were younger than eighteen years old, 15% (n=15) were ten years old or younger. The most common cause of burns was carelessness in activities involving barbecues, campfires and fondues. Mean TBSA burned was 16% (SD 12.4). 70% (n=68) had full thickness burns. 66% (n=64) needed grafting. Mean length of hospital stay was 23 days (SD 24.7). CONCLUSIONS: The use of methylated spirit is an ongoing problem, which continues to cause severe burns in adults and children. Therefore methylated spirit should be banned in households. We suggest sale only in specialised shops, clear labelling and mandatory warnings.
