    Aesthetic Outcome After Reconstruction of Complex SoftTissue Defects with Free Antero-Lateral Thigh Flap UsingSimple Equipment2015In: Journal of surgery, ISSN 2330-0914, Vol. 3, no 2-1, p. 36-41Article in journal (Refereed)
    Abstract [en]

    Aim: We aimed to assess the aesthetic outcome of surgical reconstruction by free ALT flap using binocular single-refraction magnifying glasses and a modified post- operative surveillance protocol. Methods: 16 patients were operated for free antero-lateral thigh flap to reconstruct complex soft tissue defects with a close clinical follow up protocol for post operative care depending on the attending personnel in the Plastic surgery unit, Suez Canal University hospital, Ismailia, Egypt. Aesthetic outcome was assessed using a questionnaire based on Posch et al. 2005, including the following items colour, contour, presence of hair, overall appearance and donor site scar. Results: The patients’ assessed aesthetic outcome was acceptable in majority of the cases; median score was 4 for all assessed items. Complete flap loss occurred in one case, other complications as arterial thrombosis and hematomas and infection were detected and managed accordingly with flap salvage in the 3 complicated cases. Conclusion: The result suggests that the proposed protocol is sufficient as an alternative. The aesthetic outcome assessed by the patient and the failure rate was in line with other studies.

    Division of overall duration of stay into operative stay and postoperative stay improves the overall estimate as a measure of quality of outcome in burn care.2017In: PLOS ONE, E-ISSN 1932-6203, Vol. 12, no 3, article id e0174579Article in journal (Refereed)
    Abstract [en]

    Patients and Methods: Surgically managed burn patients admitted between 2010-14 were included. Operative stay was defined as the time from admission until the last operation, postoperative stay as the time from the last operation until discharge. The difference in variation was analysed with F-test. A retrospective review of medical records was done to explore reasons for extended postoperative stay. Multivariable regression was used to assess factors associated with operative stay and postoperative stay.less thanbr /greater thanResults: Operative stay/TBSA% showed less variation than total duration/TBSA% (F test = 2.38, pless than0.01). The size of the burn, and the number of operations, were the independent factors that influenced operative stay (R2 0.65). Except for the size of the burn other factors were associated with duration of postoperative stay: wound related, psychological and other medical causes, advanced medical support, and accommodation arrangements before discharge, of which the two last were the most important with an increase of (mean) 12 and 17 days (pless than0.001, R2 0.51).less thanbr /greater thanConclusion: Adjusted operative stay showed less variation than total hospital stay and thus can be considered a more accurate outcome measure for surgically managed burns. The size of burn and number of operations are the factors affecting this outcome measure.

    Improvement in mortality at a National Burn Centre since 2000: Was it the result of increased resources?2017In: Medicine, ISSN 0025-7974, E-ISSN 1536-5964, Vol. 96, no 25, article id e6727Article in journal (Refereed)
    Abstract [en]

    Abstract The aim of this study was to find out whether the charging costs (calculated using interventional burn score) increased as mortality decreased. During the last 2 decades, mortality has declined significantly in the Linköping Burn Centre. The burn score that we use has been validated as a measure of workload and is used to calculate the charging costs of each burned patient. We compared the charging costs and mortality in 2 time periods (2000–2007 and 2008–2015). A total of 1363 admissions were included. We investigated the change in the burn score, as a surrogate for total costs per patient. Multivariable regression was used to analyze risk-adjusted mortality and burn score. The median total body surface area % (TBSA%) was 6.5% (10–90 centile 1.0–31.0), age 33 years (1.3–72.2), duration of stay/ TBSA% was 1.4 days (0.3–5.3), and 960 (70%) were males. Crude mortality declined from 7.5% in 2000–2007 to 3.4% in 2008–2015, whereas the cumulative burn score was not increased (P=.08). Regression analysis showed that risk-adjusted mortality decreased (odds ratio 0.42, P=.02), whereas the adjusted burn score did not change (P=.14, model R2 0.86). Mortality decreased but there was no increase in the daily use of resources as measured by the interventional burn score. The data suggest that the improvements in quality obtained have been achieved within present routines for care of patients (multidisciplinary/ orientated to patients’ safety).

    Needle Fasciotomy or Collagenase Injection in the Treatment of Dupuytren’s Contracture: A Retrospective Study2020In: Plastic and Reconstructive Surgery - Global Open, E-ISSN 2169-7574, Vol. 8, no 1Article, review/survey (Refereed)
    Abstract [en]

    Background: Dupuytren’s contracture is common among older people in Sweden. Previous studies comparing the treatment with an injection of collagenase with percutaneous needle fasciotomy found no differences. Methods: We retrospectively compared the degree of improvement in the deficit in extension of the joints in 2 groups of patients who had been treated with collagenase (71 fingers) or needle fasciotomy (109 fingers) before and 1 year after treatment. We compared the improvement of the extension deficit among the metacarpophalangeal (MCP) and proximal interphalangeal joints before and after the intervention; additionally, the level of improvement was classified into 3 levels (mild = 0° to 29°; moderate = 30° to 60°; considerable = 61° and more). Results: The degree of improvement of extension in the MCP joints was 11° greater in the collagenase group (P = 0.001). The number of patients who had an improvement of >60° (considerable) in extension was greater in the collagenase group (P = 0.02). Conclusion: Collagenase was more effective than needle fasciotomy in treating extension deficits of the MCP joints in Dupuytren’s contracture in this retrospective analysis. Further prospective studies are required to confirm the finding.

    A prospective randomized cost billing comparison of local fasciocutaneous perforator versus free Gracilis flap reconstruction for lower limb in a developing economy2016In: Journal of Plastic, Reconstructive & Aesthetic Surgery, ISSN 1748-6815, E-ISSN 1878-0539, Vol. 69, no 8, p. 1121-1127Article in journal (Refereed)
    Abstract [en]

    Distal half leg complex wounds are usually a formidable problem that necessitates either local or free flap coverage. The aim of this study was to compare cost billing charges in free Gracilis flap (fGF) and local fasciocutaneous perforator flap (lFPF) in reconstructing complex soft tissue leg and foot defects. Patients and methods: Thirty consecutive adult (amp;gt; 15-year-old) patients with soft tissue defects in the leg and/or foot requiring tissue coverage with a flap in the period between 2012 and 2015 were randomly assigned (block randomization) to either an fGF or lFPF procedure. The outcome measures addressed were total billed charges costs, perioperative billed charges cost, partial or complete flap loss, length of hospital stay, inpatient postsurgical care duration, complications, operating time and number of operative scrub staff. Results: One patient suffered from complete flap loss in each group. Reconstruction with lFPF showed total lower billed charges costs by 62% (2509 USD) (p amp;lt; 0.001) and perioperative billed charges cost by 54% (779 USD) (p amp;lt; 0.001), and shorter total hospital stay (36.5 days; p amp;lt; 0.001), inpatient postsurgical care duration (6.4 days; p amp;lt; 0.001), operating time (4.3 h; p amp;lt; 0.001) and fewer scrub staff (2.2 persons; p amp;lt; 0.001). Conclusion: These results suggest that neither flap is totally superior to the other; the choice should instead be based on the outcome sought and logistics. lFPF requires lower billed charges cost and resource use and saves operative time and personnel and reduces length of hospital stay. Our approach changed towards using perforator flaps in medium-sized defects, keeping the free flap option for larger defects.

    Lidocaine infusion has a 25% opioid-sparing effect on background pain after burns: A prospective, randomised, double-blind, controlled trial2020In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 46, no 2, p. 465-471Article in journal (Refereed)
    Abstract [en]

    Background

    The pain of a burn mainly results from the inflammatory cascade that is induced by the injured tissue, and is classified as background, breakthrough, procedural and postoperative pain. High doses of opioids are usually needed to treat background pain, so its management includes a combination of types of analgesia to reduce the side effects. Lidocaine given intravenously has been shown in two small, uncontrolled studies to have an appreciable effect on pain after burns.

    Objectives

    In this prospective double-blind controlled trial we aimed to examine and quantify the opioid-sparing effect of a continuous infusion of lidocaine for the treatment of background pain during the early period after a burn.

    Methods

    Adult patients injured with burns of >10 total body surface area burned (TBSA%) and treated with a morphine based patient-controlled analgesia device (PCA) were randomised to have either lidocaine infusion starting with a bolus dose (1 mg lidocaine/kg) followed by continuous infusion (180 mg lidocaine/hour) or a placebo infusion, for seven consecutive days. Total daily consumption of opioids (mg) and amount of pain (visual analogue score, VAS) were recorded.

    Results

    We included 19 patients, 10 of whom were given a lidocaine infusion. There were no differences between groups in VAS, TBSA%, time of enrolment to the study since the initial burn, or duration of hospital stay. The opioid consumption in the lidocaine group declined by roughly 25% during the period of the study.

    Conclusion

    An intravenous infusion of lidocaine was safe and had an opioid-sparing effect when treating background pain in burns.

    Use of the burn intervention score to calculate the charges of the care of burns2019In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 45, no 2, p. 303-309Article in journal (Refereed)
    Abstract [en]

    Background To our knowledge this is the first published estimate of the charges of the care of burns in Sweden. The Linköping Burn Interventional Score has been used to calculate the charges for each burned patient since 1993. The treatment of burns is versatile, and depends on the depth and extension of the burn. This requires a flexible system to detect the actual differences in the care provided. We aimed to describe the model of burn care that we used to calculate the charges incurred during the acute phase until discharge, so it could be reproduced and applied in other burn centres, which would facilitate a future objective comparison of the expenses in burn care. Methods All patients admitted with burns during the period 2010–15 were included. We analysed clinical and economic data from the daily burn scores during the acute phase of the burn until discharge from the burn centre. Results Total median charge/patient was US$ 28 199 (10th–90th centiles 4668-197 781) for 696 patients admitted. Burns caused by hot objects and electricity resulted in the highest charges/TBSA%, while charges/day were similar for the different causes of injury. Flame burns resulted in the highest mean charges/admission, probably because they had the longest duration of stay. Mean charges/patient increased in a linear fashion among the different age groups. Conclusion Our intervention-based estimate of charges has proved to be a valid tool that is sensitive to the procedures that drive the costs of the care of burns such as large TBSA%, intensive care, and operations. The burn score system could be reproduced easily in other burn centres worldwide and facilitate the comparison regardless of the differences in the currency and the economic circumstances.

    Evaluation of Glandular Liposculpture as a Single Treatment for Grades I and II Gynaecomastia2018In: Aesthetic Plastic Surgery, ISSN 0364-216X, E-ISSN 1432-5241, Vol. 42, no 2, p. 1222-1230Article in journal (Refereed)
    Abstract [en]

    Background

    Gynaecomastia is a benign enlargement of the male breast, of which the psychological burden on the patient can be considerable, with the increased risk of disorders such as depression, anxiety, and social phobia. Minimal scarring can be achieved by liposuction alone, though it is known to have a limited effect on the dense glandular and fibroconnective tissues. We know of few studies published on “liposuction alone”, so we designed this study to evaluate the outcome of combining liposuction with glandular liposculpturing through two axillary incisions as a single treatment for the management of grades I and II gynaecomastia.

    Methods

    We made a retrospective analysis of 18 patients with grade I or II gynaecomastia who were operated on by combined liposuction and glandular liposculpturing using a fat disruptor cannula, without glandular excision, during the period 2014–2016. Patient satisfaction was assessed using the Breast Evaluation Questionnaire (BEQ), which is a 5-point Likert scale (1 = very dissatisfied; 2 = dissatisfied; 3 = neither; 4 = satisfied; 5 = very satisfied). The post-operative aesthetic appearance of the chest was evaluated by five independent observers on a scale from 1 to 5 (5 = considerable improvement).

    Results

    The patient mean (SD) overall satisfaction score was 4.7 (0.7), in which 92% of the responders were “satisfied” to “very satisfied”. The mean (SD) BEQ for all questions answered increased from 2.1 (0.2) “dissatisfied” preoperatively to 4.1 (0.2) “satisfied” post-operatively. The observers’ mean (SD) rate for the improvement in the shape of the front chest wall was 4.1 (0.7). No haematomas were recorded, one patient developed a wound infection, and two patients complained of remnants of tissue. The median (IQR) body mass index was 27.4 (26.7–29.4), 11 patients had gynaecomastia grade I, and 7 patients grade II. The median (IQR) volume of aspirated fat was 700 ml (650–800), operating time was 67 (65–75) minutes, 14 patients had general anaesthesia, and hospital charges were US$ 538 (481–594).

    Conclusions

    Combined liposuction and liposculpturing using the fat disruptor cannula resulted in satisfied patients and acceptable outcomes according to the observers’ ratings. It could be a useful alternative with an outcome that corresponds to that of more expensive methods.

    Pros and Cons of Early and Late Skin Grafting in Children with Burns—Evaluation of Common Concepts2022In: European Burn Journal, E-ISSN 2673-1991, Vol. 3, no 1, p. 180-187Article in journal (Refereed)
    Abstract [en]

    Background: There is no consensus regarding the timing of surgery in children with smallerburn size, specifically in deep dermal burns. Delayed surgery has risks in terms of infection anddelayed wound healing. Early surgery also risks the removal of potentially viable tissue. Our aim wasto investigate the effect of the timing of surgical intervention on the size of the area operated on andthe time to wound healing. Methods: A retrospective analysis for all children (<18 years) with burnsize <20% body surface area (BSA%) during 2009–2020 who were operated on with a split-thicknessskin graft. The patients were grouped by the timing of the first skin graft operation: early = operatedon within 14 days of injury; delayed = operated on more than two weeks after injury. Results: A totalof 84 patients were included in the study, 43 who had an early operation and 41 who had a delayedoperation. There were no differences between the groups regarding burn size, or whether the burnswere superficial or deep. The mean duration of healing time was seven days longer in the group withdelayed operation (p = 0.001). The area operated on was somewhat larger (not significantly so) in thegroup who had early operation. Nine children had two skin graft operations, eight in the early groupand one in the delayed group (p = 0.03). Conclusion: The patients who were operated on early hadthe advantage of a shorter healing time, but there was a higher rate of complementary operationsand a tendency towards a larger burn excision.

    Development of delirium: Association with old age, severe burns, and intensive care2020In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 46, no 4, p. 797-803Article in journal (Refereed)
    Abstract [en]

    Background Delirium is defined as a disturbance of attention and awareness that develops over a short period of time, is a change from the baseline, and typically fluctuates over time. Burn care involves a high prevalence of known risk factors for delirium such as sedation, inflammation, and prolonged stay in hospital. Our aim was to explore the extent of delirium and the impact of factors associated with it for adult patients who have been admitted to hospital with burns. Methods In this retrospective study, all adult patients who had been admitted with burns during a four-year period were studied, including both those who were treated with intensive care and intermediate care only (no intensive care). Daily records of the assessment of delirium using the Nursing Delirium Screening Scale (Nu-DESC) were analysed together with age, sex, the percentage of total body surface area burned, operations, and numbers of wound care procedures under anaesthesia, concentrations of plasma C-reactive protein, and other clinical variables. Logistic regression was used to analyse factors that were associated with delirium and its effect on mortality, and linear regression was used to analyse its effect on the duration of hospital stay. Results Fifty-one patients (19%) of the total 262 showed signs of delirium (Nu-DESC score of 2 or more) at least once during their stay in hospital. Signs of delirium were recorded in 42/89 patients (47%) who received intensive care, and in 9/173 (5%) who had intermediate care. Independent factors for delirium in the multivariable regression were: age over 74 years; number of operations and wound care procedures under anaesthesia; and the provision of intensive care (area under the curve 0.940, 95% CI 0.899–0.981). Duration of hospital stay, adjusted for age and burn size, was 13.2 (95% CI 7.4–18.9, p < 0.001) days longer in the group who had delirium. We found no independent effects of delirium on mortality. Conclusion We found a strong association between delirium and older age, provision ofr intensive care, and number of interventions under anaesthesia. A further 5% of patients who did not receive intensive care also showed signs of delirium, which is a finding that deserves to be thoroughly investigated in the future.

    Burn mass casualty incidents in Europe: A European response plan within the European Union Civil Protection Mechanism2022In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 48, no 8, p. 1794-1804Article in journal (Refereed)
    Abstract [en]

    Background: Burn care is centralized in highly specialized burn centers in Europe. These centers are of limited capacity and may be overwhelmed by a sudden surge in case of a burn mass casualty incident. Prior incidents in Europe and abroad have sustained high standards of care through well-orchestrated responses to share the burden of care in several burn centers. A burn mass casualty incident in Romania in 2015 sparked an initiative to strengthen the existing EU mechanisms. This paper aims to provide insight into developing a response plan for burn mass casualties within the EU Civil Protection Mechanism. Methods: The European Burns Association drafted medical guidelines for burn mass casualty incidents based on a literature review and an in-depth analysis of the Romanian incident. An online questionnaire surveyed European burn centers and EU States for burn mass casualty preparedness. Results: The Romanian burn mass casualty in 2015 highlighted the lack of a burn-specific mechanism, leading to the late onset of international transfers. In Europe, 71% of respondents had existing mass casualty response plans, though only 35% reported having a burn-specific plan. A burns response plan for burn mass casualties was developed and adopted as a Commission staff working document in preparation for further implementation. The plan builds on the existing Union Civil Protection Mechanism framework and the standards of the WHO Emergency Medical Teams initiative to provide 1) burn assessment teams for specialized in-hospital triage of patients, 2) specialized burn care across European burn centers, and 3) medevac capacities from participating states. Conclusion: The European burn mass casualty response plan could enable the delivery of high-level burn care in the face of an overwhelming incident in an affected European country. Further steps for integration and implementation of the plan within the Union Civil Protection Mechanism framework are needed.

    Recurrent thrombocytopenia, renal failure and thymitis of unknown cause. A case report2017In: Vaskulär medicin, Vol. 33, no 3, p. 24-25Article in journal (Refereed)
    Abstract [en]

    A 45-year old man was admitted to an intensive care unit with flank pain and thrombocytopenia. He was treated for a suspected septicaemia but turned out to have signs of an unknown collagenosis which responded to plasma exchange, thymectomi and corticosteroids. Kidney biopsy revealed an intense tubulointerstitial reaction with suspected microthrombotic lesions in the vessels. The condition reoccurred with thrombocytopenia a couple of months later but responded to plasma exchange, corticosteroids and mycophenolate mofetil. An unknown collagenosis with findings of autoimmune thymitis and tubulointerstitial nephritis is the most probable cause of the condition.

    Interleukin-8 is elevated in cerebrospinal fluid following high-voltage electrical injury with late-onset paraplegia suggesting neuronal damage at the microlevel as causative factor2010In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 36, no 3, p. e7-e9Article in journal (Refereed)
    Abstract [en]

    The patient, a 31-year-old male, sustained an electric burn injury (16 kV, AC/DC) while working with electric power lines. He was acutely admitted to a national burn center in Southeast Sweden, where burns equalling 29% of the total body surface area were noted. The burns were located at the front of the abdomen, upper arms bilaterally, and the left hip region, and the lesions were estimated to be mainly of the dermal type, what was believed initially to be caused mainly by an electric flash. There were no obvious entry or exit sites of the electric current. However, myoglobin in plasma was elevated as a sign of muscular degradation, suggesting that at least some current had passed through the tissues. According to the paramedic report there was an episode of a few minutes of unconsciousness immediately after the injury, but the patient was fully awake and alert on admission. There was no concomitant trauma.

    Cardiac dysfunction after burns2008In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 34, no 5, p. 603-609Article in journal (Refereed)
    Abstract [en]

    Objectives

    Using transoesophageal echocardiography (TEE) we investigated the occurrence, and the association of possible abnormalities of motion of the regional wall of the heart (WMA) or diastolic dysfunction with raised troponin concentrations, or both during fluid resuscitation in patients with severe burns.

    Patients and methods

    Ten consecutive adults (aged 36–89 years, two women) with burns exceeding 20% total burned body surface area who needed mechanical ventilation were studied. Their mean Baux index was 92.7, and they were resuscitated according to the Parkland formula. Thirty series of TEE examinations and simultaneous laboratory tests for myocyte damage were done 12, 24, and 36 h after the burn.

    Results

    Half (n = 5) the patients had varying grades of leakage of the marker that correlated with changeable WMA at 12, 24 and 36 h after the burn (p ≤ 0.001, 0.044 and 0.02, respectively). No patient had WMA and normal concentrations of biomarkers or vice versa. The mitral deceleration time was short, but left ventricular filling velocity increased together with stroke volume.

    Conclusion

    Acute myocardial damage recorded by both echocardiography and leakage of troponin was common, and there was a close correlation between them. This is true also when global systolic function is not deteriorated. The mitral flow Doppler pattern suggested restrictive left ventricular diastolic function.

    Hemodynamic Changes During Resuscitation After Burns Using the Parkland Formula2009In: Journal of Trauma, ISSN 0022-5282, E-ISSN 1529-8809, Vol. 66, no 2, p. 329-336Article in journal (Refereed)
    Abstract [en]

    Background: The Parkland formula (2-4 mL/kg/burned area of total body surface area %) with urine output and mean arterial pressure (MAP) as endpoints; for the fluid resuscitation in burns is recommended all over the world. There has recently been a discussion on whether central circulatory endpoints should be used instead, and also whether volumes of fluid should be larger. Despite this, there are few central hemodynamic data available in the literature about the results when the formula is used correctly.

    Methods: Ten burned patients, admitted to our unit early, and with a burned area of >20% of total body sur-face area were investigated at 12, 24, and 36 hours after injury. Using transesophageal echocardiography, pulmonary artery catheterization, and transpulmonary thermodilution to monitor them, we evaluated the cardiovascular coupling when urinary output and MAP were used as endpoints.

    Results: Oxygen transport variables, heart rate, MAP, and left ventricular fractional area, did not change significantly during fluid resuscitation. Left ventricular end-systolic and end-diastolic area and global end-diastolic volume index increased from subnormal values at 12 hours to normal ranges at 24 hours after the burn. Extravascular lung intrathoracal blood volume ratio was increased 12 hours after the burn.

    Conclusions: Preload variables, global systolic function, and oxygen transport recorded simultaneously by three separate methods showed no need to increase the total fluid volume within 36 hours of a major burn. Early (12 hours) signs of central circulatory hypovolemia, however, support more rapid infusion of fluid at the beginning of treatment.

    Human cardiovascular dose-response to supplemental oxygen2007In: Acta Physiologica, ISSN 1748-1708, E-ISSN 1748-1716, Vol. 191, no 1, p. 15-24Article in journal (Refereed)
    Abstract [en]

    Aim: The aim of the study was to examine the central and peripheral cardiovascular adaptation and its coupling during increasing levels of hyperoxaemia. We hypothesized a dose-related effect of hyperoxaemia on left ventricular performance and the vascular properties of the arterial tree.

    Methods: Oscillometrically calibrated arterial subclavian pulse trace data were combined with echocardiographic recordings to obtain non-invasive estimates of left ventricular volumes, aortic root pressure and flow data. For complementary vascular parameters and control purposes whole-body impedance cardiography was applied. In nine (seven males) supine, resting healthy volunteers, aged 23–48 years, data was collected after 15 min of air breathing and at increasing transcutaneous oxygen tensions (20, 40 and 60 kPa), accomplished by a two group, random order and blinded hyperoxemic protocol.

    Results: Left ventricular stroke volume [86 ± 13 to 75 ± 9 mL (mean ± SD)] and end-diastolic area (19.3 ± 4.4 to 16.8 ± 4.3 cm2) declined (P < 0.05), and showed a linear, negative dose–response relationship to increasing arterial oxygen levels in a regression model. Peripheral resistance and characteristic impedance increased in a similar manner. Heart rate, left ventricular fractional area change, end-systolic area, mean arterial pressure, arterial compliance or carbon dioxide levels did not change.

    Conclusion: There is a linear dose–response relationship between arterial oxygen and cardiovascular parameters when the systemic oxygen tension increases above normal. A direct effect of supplemental oxygen on the vessels may therefore not be excluded. Proximal aortic and peripheral resistance increases from hyperoxaemia, but a decrease of venous return implies extra cardiac blood-pooling and compensatory relaxation of the capacitance vessels.

    Assessment of microcirculation of the skin using Tissue Viability Imaging: A promising technique for detecting venous stasis in the skin2015In: Microvascular Research, ISSN 0026-2862, E-ISSN 1095-9319, Vol. 101, p. 20-25Article in journal (Refereed)
    Abstract [en]

    Background: : Venous occlusion in the skin is difficult to detect by existing measurement techniques. Our aim was to find out whether Tissue Viability Imaging (TiVi) was better at detecting venous occlusion by comparing it with results of laser Doppler flowmetry (LDF) during graded arterial and venous stasis in human forearm skin. Methods: : Arterial and venous occlusions were simulated in 10 healthy volunteers by inflating a blood pressure cuff around the upper right arm. Changes in the concentration of red blood cells (RBC) were measured using TiVi, while skin perfusion and concentration of moving red blood cells (CMBC) were measured using static indices of LDF during exsanguination and subsequent arterial occlusion, postocclusive reactive hyperaemia, and graded increasing and decreasing venous stasis. Results: : During arterial occlusion there was a significant reduction in the mean concentration of RBC from baseline, as well as in perfusion and CMBC (p less than 0.008). Venous occlusion resulted in a significant 28% increase in the concentration of RBC (p = 0.002), but no significant change in perfusion (mean change -14%) while CMBC decreased significantly by 24% (p = 0.02). With stepwise increasing occlusion pressures there was a significant rise in the TiVi index and reduction in perfusion (p = 0.008), while the reverse was seen when venous flow was gradually restored. Conclusion: : The concentration of RBC measured with TiVi changes rapidly and consistently during both total and partial arterial and venous occlusions, while the changes in perfusion, measured by LDF, were less consistent This suggests that TiVi could be a more useful, non-invasive clinical monitoring tool for detecting venous stasis in the skin than LDF.

    Pressure-induced vasodilation and reactive hyperemia at different depths in sacral tissue under clinically relevant conditions2014In: Microcirculation, ISSN 1073-9688, E-ISSN 1549-8719, Vol. 21, no 8, p. 761-771Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To characterize pressure-induced vasodilatation and reactive hyperemia at different sacral tissue depths in different populations under clinically relevant pressure exposure.

    METHODS: Forty-two subjects (< 65 years), 38 subjects (≥ 65 years), and 35 patients (≥ 65 years) participated. Interface pressure, skin temperature, and blood flow at tissue depths of 1 mm, 2 mm, and 10 mm (using laser Doppler flowmetry and photoplethysmography) were measured in the sacral tissue before, during, and after load in a supine position.

    RESULTS: pressure-induced vasodilatation and reactive hyperemia were observed at three tissue depths. At 10 mm depth, the proportion of subjects with a lack of pressure-induced vasodilatation was higher compared to superficial depths. The patients had higher interface pressure during load than the healthy individuals, but there were no significant differences in blood flow. Twenty-nine subjects in all three study groups were identified with a lack of pressure-induced vasodilatation and reactive hyperemia.

    CONCLUSIONS: pressure-induced vasodilatation and reactive hyperemia can be measured at different tissue depths. A lack of these responses was found in healthy individuals as well as in patients indicating an innate susceptibility in some individuals, and are potential important factors to evaluate in order to better understand the etiology of pressure ulcers.

    The thyroid hormone mimetic compound KB2115 lowers plasma LDL cholesterol and stimulates bile acid synthesis without cardiac effects in humans2008In: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 105, no 2, p. 663-667Article in journal (Refereed)
    Abstract [en]

    Atherosclerotic cardiovascular disease is a major problem despite the availability of drugs that influence major risk factors. New treatments are needed, and there is growing interest in therapies that may have multiple actions. Thyroid hormone modulates several cardiovascular risk factors and delays atherosclerosis progression in humans. However, use of thyroid hormone is limited by side effects, especially in the heart. To overcome this limitation, pharmacologically selective thyromimetics that mimic metabolic effects of thyroid hormone and bypass side effects are under development. In animal models, such thyromimetics have been shown to stimulate cholesterol elimination through LDL and HDL pathways and decrease body weight without eliciting side effects. We report here studies on a selective thyromimetic [KB2115, (3-[[3,5-dibromo-4- [4-hydroxy-3-(1-methylethyl)-phenoxy]-phenyl]-amino]-3-oxopropanoic acid)] in humans. In moderately overweight and hypercholesterolemic subjects KB2115 was found to be safe and well tolerated and elicited up to a 40% lowering of total and LDL cholesterol after 14 days of treatment. Bile acid synthesis was stimulated without evidence of increased cholesterol production, indicating that KB2115 induced net cholesterol excretion. KB2115 did not provoke detectable effects on the heart, suggesting that the pharmacological selectivity observed in animal models translates to humans. Thus, selective thyromimetics deserve further study as agents to treat dyslipidemia and other risk factors for atherosclerosis. © 2007 by The National Academy of Sciences of the USA.

    A prospective longitudinal multicentre study of health related quality of life in ICU survivors with COPD2013In: Critical Care, ISSN 1364-8535, E-ISSN 1466-609X, Vol. 17, no 5, p. R211-Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Mortality amongst COPD patients treated on the ICU is high. Health-related quality of life (HRQL) after intensive care is a relevant concern for COPD patients, their families and providers of health care. Still, there are few HRQL studies after intensive care of this patient group. Our hypothesis was that HRQL of COPD patients treated on the ICU declines rapidly with time.

    METHODS: Fifty-one COPD patients (COPD-ICU group) with an ICU stay longer than 24 hours received a questionnaire at 6, 12 and 24 months after discharge from ICU. HRQL was measured using two generic instruments: the EuroQoL instrument (EQ-5D and EQ-VAS) and the Short Form 36 Health Survey (SF-36). The results were compared to HRQL of two reference groups from the general population; an age- and sex-adjusted reference population (Non-COPD reference) and a reference group with COPD (COPD reference).

    RESULTS: HRQL of the COPD-ICU group at 6 months after discharge from ICU was lower compared to the COPD reference group: Median EQ-5D was 0.66 vs. 0.73, P=0.08 and median EQ-VAS was 50 vs.55, P<0.05. There were no significant differences in the SF-36 dimensions between the COPD-ICU and COPD-reference groups, although the difference in physical functioning (PF) approached statistical significance (P=0.059). Patients in the COPD-ICU group who were lost to follow-up after 6 months had low HRQL scores at 6 months. Scores for patients who died were generally lower compared to patients who failed to respond to the questionnaire. The PF and social functioning (SF) scores in those who died were significantly lower compared to patients with a complete follow up. HRQL of patients in the COPD-ICU group that survived a complete 24 months follow up was low but stable with no statistically significant decline from 6 to 24 months after ICU discharge. Their HRQL at 24 months was not significantly different from HRQL in the COPD reference group.

    CONCLUSIONS: HRQL in COPD survivors after intensive care was low but did not decline from 6 to 24 months after discharge from ICU. Furthermore, HRQL at 24 months was similar to patients with COPD who had not received ICU treatment.

    A case-control study of the influence of the ICU-diary concept on mastery and hopelessness six months after critical illnessManuscript (preprint) (Other academic)
    Abstract [en]

    The ICU-diary concept is associated with less post-traumatic stress syndrome and improved perceived health-related quality-of-life (HRQoL) after critical illness, but little is known about its effect on the coping- mastery process, or whether it reduces hopelessness.

    Objective: To see if the ICU-diary concept improves the patient’s ability to master his/her situation after critical illness, and if it reduces the feeling of hopelessness.

    Design: Case control study (subgroup analysis of a multi-centre study on health-related quality-of-life (HRQoL).

    Setting: Non-academic 8-bed general ICU.

    Patients: Adults admitted between March 2002 and June 2004.

    Measurements: Mastery and hopelessness were determined using validated questionnaires (the Mastery-Coping scale and a consolidated 2–item hopelessness questionnaire) which were sent home to patients 6 months after critical illness. Responses were compared between patients that received (Cases: n=38) or did not receive an ICU-diary (Controls: n=76) . Diaries were used when a long and complicated stay on the ICU was expected. Controls were matched with diary patients by gender and age. The effect of the ICU-diary was also examined using a multiple regression model.

    Results: The ICU-diary concept group scored significantly higher than the No-diary group in mastery (22.1 vs. 20.4, P<0.05) and lower in hopelessness scores (1.3 vs. 1.6, P<0.05). The positive influence of the ICU-diary disappeared after adjustment for confounding factors in a multiple regression model.

    Conclusion: We were unable to verify any positive influence of the ICU-diary concept on mastery and hopelessness 6 months after critical illness.

    Long-term effect of the ICU-diary concept on quality of life after critical illness2010In: ACTA ANAESTHESIOLOGICA SCANDINAVICA, ISSN 0001-5172, Vol. 54, no 6, p. 736-743Article in journal (Refereed)
    Abstract [en]

    Background Critically ill patients often spend time in the intensive care unit (ICU) either unconscious or sedated. On recovery, they are often in a state of confusion with memory loss that may be associated with a longstanding reduction in health-related quality of life (QoL). We hypothesised that the ICU-diary concept could improve their QoL by filling in their memory gaps. Methods A non-randomised, prospective study in a non-academic eight-bedded general ICU. A group of patients (n=38) were selected to receive the ICU-diary concept (keeping a diary with photos while on the ICU plus a follow-up meeting) when a long and complicated course was expected. Health-related QoL at 6, 12, 24 and 36 months was compared with a group that did not receive the ICU-diary (n=224). The Medical Outcomes Study 36-Item Short-Form (SF-36) was used to measure health-related QoL. Multiple regression models adjusted for age, sex, illness severity, pre-existing disease and diagnostic category was used to analyse the effects of the ICU-diary concept at 6 months, and changes over time were analysed using repeated measures MANOVA. Results Crude and adjusted scores for two dimensions of SF-36 (general health and vitality) and the physical component summary score were significantly higher at 6 months in the ICU-diary group (P andlt; 0.05) and some of the effects remained during the 3-year follow-up period (P andlt; 0.05). Conclusion The ICU-diary concept was associated with improved health-related QoL during the 3-year follow-up period after a critical illness. The effect of this intervention needs to be confirmed in a larger randomised study.

    Deaths caused by injury among people of working age (18-64) are decreasing, while those among older people (64+) are increasing2018In: European Journal of Trauma and Emergency Surgery, ISSN 1863-9933, E-ISSN 1863-9941, Vol. 44, no 4, p. 589-596Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Injury is an important cause of death in all age groups worldwide, and contributes to many losses of human and economic resources. Currently, we know a few data about mortality from injury, particularly among the working population. The aim of the present study was to examine death from injury over a period of 14 years (1999-2012) using the Swedish Cause of Death Registry (CDR) and the National Patient Registry, which have complete national coverage.

    METHOD: CDR was used to identify injury-related deaths among adults (18 years or over) during the years 1999-2012. ICD-10 diagnoses from V01 to X39 were included. The significance of changes over time was analyzed by linear regression.

    RESULTS: The incidence of prehospital death decreased significantly (coefficient -0.22, r (2) = 0.30; p = 0.041) during the study period, while that of deaths in hospital increased significantly (coefficient 0.20, r (2) = 0.75; p < 0.001). Mortality/100,000 person-years in the working age group (18-64 years) decreased significantly (coefficient -0.40, r (2) = 0.37; p = 0.020), mainly as a result of decrease in traffic-related deaths (coefficient -0.34, r (2) = 0.85; p < 0.001). The incidence of deaths from injury among elderly (65 years and older) patients increased because of the increase in falls (coefficient 1.71, r (2) = 0.84; p < 0.001) and poisoning (coefficient 0.13, r (2) = 0.69; p < 0.001).

    CONCLUSION: The epidemiology of injury in Sweden has changed during recent years in that mortality from injury has declined in the working age group and increased among those people 64 years old and over.

    Change in child mortality patterns after injuries in Sweden: a nationwide 14-year study.2017In: European Journal of Trauma and Emergency Surgery, ISSN 1863-9933, E-ISSN 1863-9941, Vol. 43, no 3, p. 343-349Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Sweden has one of the world's lowest child injury mortality rates, but injuries are still the leading cause of death among children. Child injury mortality in the country has been declining, but this decline seems to decrease recently. Our objective was therefore to further examine changes in the mortality of children's death from injury over time and to assess the contribution of various effects on mortality. The underlying hypothesis for this investigation is that the incidence of lethal injuries in children, still is decreasing and that this may be sex specific.

    PATIENTS AND METHODS: We studied all deaths from injury in Sweden under-18-year-olds during the 14 years 1999-2012. We identified those aged under 18 whose underlying cause of death was recorded as International Classification of Diseases, 10th Revision (ICD-10) diagnosis from V01 to X39 in the Swedish cause of death, where all dead citizens are registered.

    RESULTS: From the 1 January 1999 to 31 December 2012, 1213 children under the age of 18 died of injuries in Sweden. The incidence declined during this period (r = -0.606, p = 0.02) to 3.3 deaths/100,000 children-years (95 % CI 2.6-4.2). Death from unintentional injury was more common than that after intentional injury (p < 0.0001). There was a reduction in the incidence of unintentional injuries during the study period (r = -0.757, p = 0.03). The most common causes of death were injury to the brain (n = 337, 41 %), followed by drowning (n = 109, 13 %). The number of deaths after intentional injury increased (r = 0.585, p = 0.03) and at the end of the period was 1.5 deaths/100,000 children-years. The most common causes of death after intentional injuries were asphyxia (n = 177, 45 %), followed by injury to the brain (n = 76, 19 %).

    DISCUSSION: Mortality patterns in injured children in Sweden have changed from being dominated by unintentional injuries to a more equal distribution between unintentional and intentional injuries as well as between sexes and the overall rate has declined further. These findings are important as they might contribute to the preventive work that is being done to further reduce mortality in injured children.

    Improving burn depth assessment for pediatric scalds by AI based on semantic segmentation of polarized light photography images2021In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 47, no 7, p. 1586-1593Article in journal (Refereed)
    Abstract [en]

    This paper illustrates the efficacy of an artificial intelligence (AI) (a convolutional neural network, based on the U-Net), for the burn-depth assessment using semantic segmentation of polarized high-performance light camera images of burn wounds. The proposed method is evaluated for paediatric scald injuries to differentiate four burn wound depths: superficial partial-thickness (healing in 0–7 days), superficial to intermediate partial-thickness (healing in 8–13 days), intermediate to deep partial-thickness (healing in 14–20 days), deep partial-thickness (healing after 21 days) and full-thickness burns, based on observed healing time.

    In total 100 burn images were acquired. Seventeen images contained all 4 burn depths and were used to train the network. Leave-one-out cross-validation reports were generated and an accuracy and dice coefficient average of almost 97% was then obtained. After that, the remaining 83 burn-wound images were evaluated using the different network during the cross-validation, achieving an accuracy and dice coefficient, both on average 92%.

    This technique offers an interesting new automated alternative for clinical decision support to assess and localize burn-depths in 2D digital images. Further training and improvement of the underlying algorithm by e.g., more images, seems feasible and thus promising for the future.

    Tensor Decomposition for Colour Image Segmentation of Burn Wounds2019In: Scientific Reports, E-ISSN 2045-2322, Vol. 9, article id 3291Article in journal (Refereed)
    Abstract [en]

    Research in burns has been a continuing demand over the past few decades, and important advancements are still needed to facilitate more effective patient stabilization and reduce mortality rate. Burn wound assessment, which is an important task for surgical management, largely depends on the accuracy of burn area and burn depth estimates. Automated quantification of these burn parameters plays an essential role for reducing these estimate errors conventionally carried out by clinicians. The task for automated burn area calculation is known as image segmentation. In this paper, a new segmentation method for burn wound images is proposed. The proposed methods utilizes a method of tensor decomposition of colour images, based on which effective texture features can be extracted for classification. Experimental results showed that the proposed method outperforms other methods not only in terms of segmentation accuracy but also computational speed.

    Time-Independent Prediction of Burn Depth using Deep Convolutional Neural Networks2019In: Journal of Burn Care & Research, ISSN 1559-047X, E-ISSN 1559-0488, Vol. 40, no 6, p. 857-863Article in journal (Refereed)
    Abstract [en]

    We present in this paper the application of deep convolutional neural networks, which are a state-of-the-art artificial intelligence (AI) approach in machine learning, for automated time-independent prediction of burn depth. Colour images of four types of burn depth injured in first few days, including normal skin and background, acquired by a TiVi camera were trained and tested with four pre-trained deep convolutional neural networks: VGG-16, GoogleNet, ResNet-50, and ResNet-101. In the end, the best 10-fold cross-validation results obtained from ResNet- 101 with an average, minimum, and maximum accuracy are 81.66%, 72.06% and 88.06%, respectively; and the average accuracy, sensitivity and specificity for the four different types of burn depth are 90.54%, 74.35% and 94.25%, respectively. The accuracy was compared to the clinical diagnosis obtained after the wound had healed. Hence, application of AI is very promising for prediction of burn depth and therefore can be a useful tool to help in guiding clinical decision and initial treatment of burn wounds.

    A prospective dual-centre intra-individual controlled study for the treatment of burns comparing dermis graft with split-thickness skin auto-graft2022In: Scientific Reports, E-ISSN 2045-2322, Vol. 12, no 1, article id 21666Article in journal (Refereed)
    Abstract [en]

    To investigate if donor and recipient site morbidity (healing time and cosmesis) could be reduced by a novel, modified split-thickness skin grafting (STSG) technique using a dermal component in the STSG procedure (DG). The STSG technique has been used for 150 years in surgery with limited improvements. Its drawbacks are well known and relate to donor site morbidity and recipient site cosmetic shortcomings (especially mesh patterns, wound contracture, and scarring). The Dermal graft technique (DG) has emerged as an interesting alternative, which reduces donor site morbidity, increases graft yield, and has the potential to avoid the mesh procedure in the STSG procedure due to its elastic properties. A prospective, dual-centre, intra-individual controlled comparison study. Twenty-one patients received both an unmeshed dermis graft and a regular 1:1.5 meshed STSG. Aesthetic and scar assessments were done using The Patient and Observer Scar Assessment Scale (POSAS) and a Cutometer Dual MPA 580 on both donor and recipient sites. These were also examined histologically for remodelling and scar formation. Dermal graft donor sites and the STSG donor sites healed in 8 and 14 days, respectively (p < 0.005). Patient-reported POSAS showed better values for colour for all three measurements, i.e., 3, 6, and 12 months, and the observers rated both vascularity and pigmentation better on these occasions (p < 0.01). At the recipient site, (n = 21) the mesh patterns were avoided as the DG covered the donor site due to its elastic properties and rendered the meshing procedure unnecessary. Scar formation was seen at the dermal donor and recipient sites after 6 months as in the standard scar healing process. The dermis graft technique, besides potentially rendering a larger graft yield, reduced donor site morbidity, as it healed faster than the standard STSG. Due to its elastic properties, the DG procedure eliminated the meshing requirement (when compared to a 1:1.5 meshed STSG). This promising outcome presented for the DG technique needs to be further explored, especially regarding the elasticity of the dermal graft and its ability to reduce mesh patterns.

    Measurement of depth of burns by laser Doppler perfusion imaging2001In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 27, no 6, p. 561-568Article in journal (Refereed)
    Abstract [en]

    Laser Doppler perfusion imaging (LDPI), is a further development in laser Doppler flowmetry (LDF). Its advantage is that it enables assessment of microvascular blood flow in a predefined skin area rather than, as for LDF, in one place. In many ways this method seems to be more promising than LDF in the assessment of burn wounds. However, several methodological issues that are inherent in the LDPI technique, and are relevant for the assessment of burn depth, must be clarified. These include the effect of scanning distance, curvature of the tissue, thickness of topical wound dressings, and pathophysiological effects of skin colour, blisters, and wound fluids. Furthermore, we soon realised that to examine the perfusion image generated by LDPI adequately the process of analysis was appreciably improved by the simultaneous use of digital photography. In the present investigation we used both in vitro and in vivo models and also examined burned patients, and found that the listed factors all significantly affected the LDPI output signal. However, if these factors are known to the examiner, most of them can be adjusted for. If the technique is further improved by minimizing such effects and by reducing the practical difficulties of applying it to a burned patient in the burns unit, the technique may find uses in everyday clinical decision-making.

    A protocol for iontophoresis of acetylcholine and sodium nitroprusside that minimises nonspecific vasodilatory effects2004In: Microvascular research, ISSN 0026-2862, Vol. 67, no 2, p. 197-202Article in journal (Refereed)
    Abstract [en]

    Iontophoresis of vasoactive substances is a promising tool for studying pharmacological aspects of the (patho)physiology of the microvasculature. However, nonspecific microvascular responses are a common problem in most protocols used. We studied the effect of current density (mA/cm2), charge density (mC/cm2), drug concentration (mass %) and vehicle concentration (M) on the nonspecific vasodilatation during iontophoresis of sodium chloride, acetylcholine (ACh) and sodium nitroprusside (SNP).

    We found that nonspecific vasodilatation depended on current density and charge density in both anodal and cathodal iontophoresis. The responses to ACh and SNP were dependent on current density, charge density and drug concentration. We found that by limiting current density (<0.01 mA/cm2) and charge density (<7.8 mC/cm2) and with adjusted concentrations for drugs and vehicles, it is possible to prevent nonspecific effects during iontophoresis of ACh and SNP, while maximum drug effects (plateaus in the dose–response curves) are still obtained. These new findings are important for future iontophoresis studies in which vasoactive drugs are used to assess microvascular function because the presented approach has advantages compared to older techniques, which mainly have attempted to suppress or compensate for the nonspecific responses during iontophoresis by the use of local anaesthetics or the measurement of drug-minus-vehicle responses, both of which present well-known experimental shortcomings.

    Nonspecific vasodilatation during transdermal iontophoresis: the effect of voltage over the skin2003In: Microvascular research, ISSN 0026-2862, Vol. 65, no 3, p. 172-178Article in journal (Refereed)
    Abstract [en]

    We used laser Doppler perfusion imaging (LDPI) to study nonspecific vasodilatation during iontophoresis. In iontophoresis studies, nonspecific vasodilatation occurs as a result either of galvanic currents or of the applied voltage over the skin. We made dose–response measurements to study the effect of ionic strength of the vehicle on the nonspecific vasodilatation during iontophoresis of sodium chloride and deionized water, while we monitored the voltage over the skin. We found that anodal and cathodal ionotophoresis induced a voltage over the skin that was dependent on the ionic strength of the test solution. The nonspecific vasodilatation during anodal iontophoresis was less pronounced than during cathodal iontophoresis, and was independent of the voltage over the skin. The nonspecific vasodilatation in cathodal iontophoresis was related to the voltage over the skin, and was possibly mediated by depolarization of local sensory nerves. In experiments using cathodal iontophoresis, therefore, the ionic strengths of the vehicle and the drug are important when vasoactive drugs are examined, as the nonspecific vasodilatation needs to be controlled for. As the vasodilatation that we observed was heterogeneously distributed within the area of iontophoresis, LDPI may provide more accurate measurements than conventional laser Doppler perfusion monitoring.

    Comparison between erector spinae plane block and paravertebral block regarding postoperative analgesic consumption following breast surgery: a randomized controlled study2022In: BMC Anesthesiology, ISSN 1471-2253, E-ISSN 1471-2253, Vol. 22, no 1, article id 189Article in journal (Refereed)
    Abstract [en]

    Background: Pain control following breast surgery is of utmost importance in order to reduce the chance of chronic pain development, and facilitate early rehabilitation. The erector spinae plane block (ESPB) is a recently developed regional anaesthesia procedure successfully used for different types of surgical procedures including thoracic and abdominal surgeries. Methods: A double-blind, randomized, controlled trial was conducted on 90 patients who were scheduled for modified radical mastectomy (MRM). Patients were randomly categorized into groups I (women who underwent ESPB), II (women who underwent paravertebral block (PVB), and III (women who underwent general anaesthesia). Results: The ESPB (4.9 +/- 1.2 mg) and PVB (5.8 +/- 1.3 mg) groups had significantly lower total morphine consumption than the control group had (16.4 +/- 3.1 mg; p < 0.001). Notably, patients in the ESPB group had insignificantly lower morphine consumption than those in the PVB group had (p= 0.076). Moreover, patients in the ESPB and PVB groups had a significantly longer time to first required anaesthesia than those in the control group (7.9 +/- 1.2 versus 7.5 +/- 0.9 versus 2 +/- 1.2 h, respectively; p<0.001).The postoperative visual analog scale scores were lower in the ESPB and PVB groups than in the control group on the first 24 h after the procedure (p< 0.001). Conclusion: ESPB and PVB provide effective postoperative analgesia for women undergoing MRM. The ESPB appears to be as effective as the PVB.

    Experimental study of the effects of nitroglycerin, botulinum toxin A, and clopidogrel on bipedicled superficial inferior epigastric artery flap survival.2022In: Scientific Reports, E-ISSN 2045-2322, Vol. 12, no 1, article id 20891Article in journal (Refereed)
    Abstract [en]

    Beneficial effects could be achieved by various agents such as nitroglycerin, botulinum toxin A (BoTA), and clopidogrel to improve skin flap ischaemia and venous congestion injuries. Eighty rats were subjected to either arterial ischaemia or venous congestion and applied to a bipedicled U-shaped superficial inferior epigastric artery (SIEA) flap with the administration of nitroglycerin, BoTA, or clopidogrel treatments. After 7 days, all rats were sacrificed for flap evaluation. Necrotic area percentage was significantly minimized in flaps treated with clopidogrel (24.49%) versus the ischemic flaps (34.78%); while nitroglycerin (19.22%) versus flaps with venous congestion (43.26%). With ischemia, light and electron microscopic assessments revealed that nitroglycerin produced degeneration of keratinocytes and disorganization of collagen fibers. At the same time, with clopidogrel administration, there was an improvement in the integrity of these structures. With venous congestion, nitroglycerin and BoTA treatments mitigated the epidermal and dermal injury; and clopidogrel caused coagulative necrosis. There was a significant increase in tissue gene expression and serum levels of vascular endothelial growth factor (VEGF) in ischemic flaps with BoTA and clopidogrel, nitroglycerin, and BoTA clopidogrel in flaps with venous congestion. With the 3 treatment agents, gene expression levels of tumor necrosis factor-α (TNF-α) were up-regulated in the flaps with ischemia and venous congestion. With all treatment modalities, its serum levels were significantly increased in flaps with venous congestion and significantly decreased in ischemic flaps. Our analyses suggest that the best treatment option for ischemic flaps is clopidogrel, while for flaps with venous congestion are nitroglycerin and BoTA.

    Laser speckle contrast imaging in children with scalds: Its influence on timing of intervention, duration of healing and care, and costs2019In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 45, no 4, p. 798-804Article in journal (Refereed)
    Abstract [sv]

    Background

    Scalds are the most common type of burn injury in children, and the initial evaluation of burn depth is a problem. Early identification of deep dermal areas that need excision and grafting would save unnecessary visits and stays in hospital. Laser speckle contrast imaging (LSCI) shows promise for the evaluation of this type of burn. The aim of this study was to find out whether perfusion measured with LSCI has an influence on the decision for operation, duration of healing and care period, and costs, in children with scalds.

    Methods

    We studied a group of children with scalds whose wounds were evaluated with LSCI on day 3–4 after injury during the period 2012–2015. Regression (adjustment for percentage total body surface area burned (TBSA%), age, and sex) was used to analyse the significance of associations between degree of perfusion and clinical outcome.

    Results

    We studied 33 children with a mean TBSA% of 6.0 (95% CI 4.4–7.7)%. Lower perfusion values were associated with operation (area under the receiver-operating characteristic curve 0.86, 95% CI 0.73–1.00). The perfusion cut-off with 100% specificity for not undergoing an operation was ≥191 PU units (66.7% sensitivity and 72.7% accurately classified). Multivariable analyses showed that perfusion was independently associated with duration of healing and care period.

    Conclusion

    Lower perfusion values, as measured with LSCI, are associated with longer healing time and longer care period. By earlier identification of burns that will be operated, perfusion measurements may further decrease the duration of care of burns in children with scalds.

    Changes in patterns of treatment of burned children at the Linkoping Burn Centre, Sweden, 2009-20142017In: Burns, ISSN 0305-4179, E-ISSN 1879-1409, Vol. 43, no 5, p. 1111-1119Article in journal (Refereed)
    Abstract [en]

    Introduction: Children are a relatively large group among patients with burns in Sweden. We changed the management of childrens burns to a flexible, outpatient-based plan. The aim was to follow up the outpatient management for childrens burns during the period 20092014, and track it, to find out to what extent the patients had been treated flexibly as outpatients, and to clarify the reasons behind those who did not fit in the plan. Methods: Descriptive retrospective analysis dividing the patients into three groups: inpatients only, flexible management, and outpatients. Other variables recorded included: age, sex, percentage total body surface area burned (TBSA%), percentage full thickness burn (FTB%), cause of burn, county of residence, operations required, number of visits to the outpatient department, costs, and duration of overnight stay in the hospital. Results: The study group included 620 children: nine were managed strictly as inpatients, 204 as flexible outpatients, and 407 strictly as outpatients. Among the total there were 269 children who came from remote areas (43%), and of these 260 were treated as outpatients and flexible outpatients. Median TBSA% in the whole group was 1 (10th-90th centile 0-9) with the biggest median TBSA% 12 (5-38) in the inpatient group. The most common cause of injury was scalds (332/620,-54%). Costs/patient (US$) was lower in the flexible outpatient group than in the inpatient group (median 10 557 (3213-35802) and 35343 (7344-66554), respectively). Conclusion: Based on the results, we expect that the flexible outpatient treatment plan for children with minor to moderate burns can be expanded in the future. The results encourage us to continue the service and to further reduce duration of stay in hospital below the level already achieved (25% of the whole period of care). (C) 2017 Elsevier Ltd and ISBI.
