Effectiveness of medical hypnosis for pain reduction and faster wound healing in pediatric acute burn injury: study protocol for a randomized controlled trial

Optimizing burn wound procedural pain control, efficiency, and satisfaction through integrated nurse and physician education

Herein, we report the results of a quality improvement project (QI). Following a review of the burn unit practices, a nursing-led, physician supported educational intervention regarding optimal timing, dosage, and indication for medications used during hydrotherapy, including midazolam and opioids, was implemented. We hypothesized that such intervention would support improvement in both nurse and patient satisfaction with pain control management. Patients undergoing hydrotherapy were surveyed. Demographics, opioid dose prescribed (oral morphine equivalents), midazolam use, timing of administration, and adverse events were collected. Patient pain scores (1-10) before and after hydrotherapy and patient and nurse satisfaction scores (1-10) after hydrotherapy were collected. The pre- and post-education populations were compared. P < 0.05 was considered significant. Post-education, administration of opioids (59.1% v. 0%, p < 0.001) and midazolam (59.1% vs. 10.4%; p < 0.001) prior to hydrotherapy significantly improved, leading to fewer patients requiring rescue opioids during hydrotherapy (25% vs. 74%, p < 0.001). Hydrotherapy duration significantly decreased post-education (19 [13.3-30] min vs. 32 [18-43] min, p = 0.003). Nurses' ratings of their patient's pain control (9 [7.3-10] vs. 7.5 [6-9], p = 0.004) and ease of procedure (10 [9,10] vs. 9 [7.8-10], p = 0.037) significantly improved. Patients' pain management satisfaction rating did not change, but the number of subjects rating their pain management as excellent tended to increase (36.4% vs. 20%, p = 0.077). Nursing led, physician supported, education can improve medication administration prior to and during hydrotherapy, increasing the ease of the procedure as well as staff satisfaction.

Effects of non-pharmacological interventions on pain intensity of children with burns: A systematic review and meta-analysis

Pain is one of the complications associated with burns, which can lead to anxiety and sleeplessness in children. Various studies evaluated the effects of non-pharmacological interventions on burn wound care. The present study was conducted to determine the effects of non-pharmacological interventions on pain intensity of children with burns. A comprehensive systematic search was conducted in various international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Non-pharmacological', 'Virtual reality', 'Pain', 'Burn', 'Wound' and 'Child' from the earliest to December 1, 2022. The risk of bias in the final articles was also assessed with the Version 2 of the Cochrane risk-of-bias tool for randomised trials (RoB 2). Finally, a total of 1005 burn patients were included in 19 studies. The age range of the patients was from 0.5 to 19 years. Of the participants, 50.05% were in the intervention group. All studies had a randomised clinical trial design. The results found that non-pharmacological interventions significantly reduced pain intensity in children (ES: -0.73, 95% CI: -1.08 to -0.38, Z = 4.09, I2 :79.8, P < .001). Virtual reality (VR) (ES: -0.54, 95% CI: -1.19 to -0.18, Z = 2.90, I2 :72.9%, P = .004) and non-VR (ES: -0.86, 95% CI: -1.45 to -0.27, Z = 2.86, I2 :91.4%, P = .04) interventions decreased pain intensity significantly in children based sub-group analysis. Non-pharmacological interventions significantly reduced the pain intensity of dressing removal (ES: -0.77, 95% CI: -1.34 to -0.20, Z = 66.3, I2 :91.8%, P = .008), dressing application (ES: -0.53, 95% CI: -0.97 to -0.09, Z = 2.37, I2 :60.8%, P = .02), and physical therapy (ES: -1.18, 95% CI: -2.10 to -0.26, Z = 2.51, I2 :88.0%, P = .01). Also, interventions reduced the pain of burn wound care (ES: -0.29, 95% CI: -1.01 to 0.44, Z = 0.78, I2 :72.6%, P = .43), but it was statistically insignificant. In sum, the result of the present study indicated that using non-pharmacological interventions significantly reduced pain intensity in children. The reduction of pain intensity was greater in non-VR than in VR interventions. Future studies should focus on comparing VR interventions with non-VR and single versus multi-modal distraction to clarify the effectiveness of each.

Hypnotherapy and IBS: Implicit, long-term stress memory in the ENS?

The association between irritable bowel syndrome (IBS) and psychiatric and mood disorders may be more fundamental than was previously believed. Prenatal, perinatal, postnatal, and early-age conditions can have a key role in the development of IBS. Subthreshold mental disorders (SMDs) could also be a significant source of countless diverse diseases and may be a cause of IBS development. We hypothesize that stress-induced implicit memories may persist throughout life by epigenetic processes in the enteric nervous system (ENS). These stress-induced implicit memories may play an essential role in the emergence and maintenance of IBS. In recent decades, numerous studies have proven that hypnosis can improve the primary symptoms of IBS and also reduce noncolonic symptoms such as anxiety and depression and improve quality of life and cognitive function. These significant beneficial effects of hypnosis on IBS may be because hypnosis allows access to unconscious brain processes.

Modern Aspects of Burn Injury Immunopathogenesis and Prognostic Immunobiochemical Markers (Mini-Review)

Burn injuries are among the most common peacetime injuries, with mortality ranging from 2.3% to 3.6%. At the same time, 85–90% of patients with burns are people of working age and children. Burn injury leads to metabolic disorders and systemic inflammatory response, inefficient energy consumption, and other physiological changes that can lead to dysfunction of organs and systems. The most formidable complication of burn injuries is sepsis mediated by multiple organ failure, the most common cause of poor prognosis in patients and has specific differences in these injuries. The purpose of this article was to dwell in detail on the most promising immunobiochemical markers of sepsis in the format of a mini-review, based on the main aspects of the immunopathogenesis of this complication. The pathogenesis of a burn injury and any general pathological process is based on an inflammatory reaction and large-scale changes in the skin and mucous membranes. This review is devoted to the progress in understanding the main aspects of the immunopathogenesis of burn lesions and the features of post-burn immune dysfunction, manifested by disorders in the innate and adaptive immunity systems. Attention is focused on the role in the immunopathogenesis of the development of systemic and local disorders in burn injury. Characterization of primary immunobiochemical markers of burn injury (cytokines, growth factors, C-reactive protein, procalcitonin, presepsin, matrix metalloproteinases, reactive oxygen species, nitric oxide, hemostasis parameters) is presented. The problem of treating burn lesions is associated with constant monitoring of the condition of patients and regular monitoring of specific immunobiochemical markers predicting sepsis for the timely initiation of a specific therapy.

Relieving pain and distress symptoms in the outpatient burn clinic: The contribution of a medical clown

CONTEXT

High levels of pain and emotional distress characterize the experience of patients, at burn outpatient clinic and reflect on their accompanying persons and the medical personal.

OBJECTIVES

To examine the effect of a medical clown presence on: the patients' pain and distress levels as perceived by the patient and by their accompanying persons, and the emotional response of healthcare personnel.

METHODS

A yearlong prospective observational comparative study in the burn outpatient clinic, operating twice a week, with a medical clown's presence once a week [Exposure Group - EG] versus clinic without clown presence [Non exposure Group- NEG]. Patients and accompanying persons filled pain [WBS, VAS] and emotional distress [SUDS] questionnaires regarding the patient's experience: before (T1) and after treatment (T2). The clinic personnel filled SUDS at the beginning and the end of the clinic working hours.

RESULTS

Significantly lower WBS, VAS, and SUDS scores were reported at T2 in the EG as compared to the NEG both in patients and in the accompanying persons' evaluations. Personnel SUDS were affected in a similar manner.

CONCLUSION

Presence of a medical clown induced a positive atmosphere in the clinic. It is possible that the effect of humor through stress reduction mechanism lessened agony. Furthermore, the distraction the clown evoked played a role in the decrease of pain and emotional distress. We recommend implementing psychosocial oriented interventions such as those performed by a medical clown to improve the emotional atmosphere in the ambulatory clinic of patients, accompanying persons and healthcare personnel.

Nano-Hydrogel for the Treatment of Depression and Epilepsy

This article first combines nano-carrier technology, the electrophysiological mechanism of seizures, and brain targeting technology to prepare new nano-hydrogels. Secondly, through the discharge information generated during the seizure and the electric field responsiveness of the nano-hydrogel, the free drug concentration in the brain area related to the seizure is increased, thereby, limiting the abnormal discharge of the focus to the local area and suppressing it in time. Finally, this article examines the impact of nano-hydrogel on the epilepsy and depression using relevant studies. The experimental observations revealed that the yield of the nano-hydrogel synthesized after 24 h of sapon-free emulsion polymerization was 50 to 70%, the swelling rate was 400 to 1700%, and the viscosity of the 20 mg/mL nano-hydrogel dispersion was 3.9 to 17.0 mPa· s. Furthermore, because the total efficiency was 0.952, the nano-hydrogels have a reduced recurrence rate and a better effect on the depression improvement.

Stress-Reducing Psychological Interventions as Adjuvant Therapies for Diabetic Chronic Wounds

BACKGROUND

Diabetic foot ulcers (DFUs) are a major complication of diabetes mellitus and a leading cause of lower limb amputation. Interventions to reduce psychological stress may have the potential to improve self-care and greatly reduce the morbidity and mortality associated with DFU. This review is focused on the consequences of psychological stress in wound healing and reflects on the effects of currently used psychological stress-reducing interventions in patients with DFU, proposing new applications for currently used stress-reduction interventions.

RESULTS

Stress is a natural and fundamental survival mechanism that becomes harmful when chronic. DFU is associated with high levels of anxiety and chronic psychological stress. Chronic stressinduced cortisol and adrenaline release impair wound healing, independently of the stressor. Psychological stress-reducing interventions, such as relaxation with guided imagery, biofeedback-assisted relaxation, mindfulness-based strategies, and hypnosis, can lead to a reduction in perceived stress and improve wound healing by reducing wound inflammation and pain while improving glycemic control. All stress reduction interventions also lead to pain relief and improved patient's quality of life.

CONCLUSION

Psychological stress-reducing interventions are promising adjuvant therapies for DFU. Their clinical application can improve self-care by tackling patient's expectations, anxieties, and fears. They can also help patients manage stress and pain while reducing wound inflammation and improving wound healing.

The effect of guided imagery on the quality and severity of pain and pain-related anxiety associated with dressing changes in burn patients: A randomized controlled trial

Pain and anxiety caused by burn dressing change are one of the major issues in burn patients. In this regard, guided imagery as a complementary method can be effective in reducing the levels of anxiety and pain. This method is the process of creating mental images and using sensory features through the individual's imagination and memory that facilitate the achievement of desired therapeutic outcomes. Therefore, this study was aimed at determining the effect of guided imagery on the quality and severity of pain and pain-related anxiety associated with dressing change in burn patients. This is a single-blinded randomized controlled trial in which a total of 70 burn patients were enrolled using convenience sampling and randomly allocated to two groups of intervention and control (n = 35 in each group). Each patient in the intervention group received four sessions of guided imagery during four consecutive days (one session a day) using a headphone. Then in both groups, the level of pain was assessed after the dressing change and the level of pain-related anxiety was assessed before the dressing change (between the end of the intervention and the initiation of dressing change). Data were collected using a demographic questionnaire, the Visual Analog Scale (VAS), the short-form McGill Pain Questionnaire (SF-MPQ), and the Burn Specific Pain Anxiety Scale (BSPAS). Data were first entered into the IBM SPSS Statistics for Windows, version 25.0 and then analyzed using repeated-measures Analysis of Variance. The repeated measures ANOVA indicated the mean score of the quality and severity of pain and pain-related anxiety differed statistically and significantly after the intervention (during the four sessions) compared to before it (baseline) in the intervention group (p < 0.001). The independent-samples t-test indicated a statistically significant difference in the mean scores of the quality and severity of pain and pain-related anxiety between the two groups (p < 0.001). This difference was found to be significant from the second session onwards (p < 0.001). Medical staff, including physicians, nurses and other healthcare professionals, are responsible for developing strategies to manage complications of burn injuries. Considering the effectiveness of guided imagery in reducing anxiety and pain in burn patients, it is recommended to use this method of complementary medicine to manage stress, anxiety, and pain in these patients.

Effective Strategies to Deal With Infection in Burn Patient

Treatment of bacterial infection is difficult. Treatment protocol of burned patient is hard. Furthermore, treatment in burned patients is accompanied with problems such as complexity in diagnosis of infection's agent, multiple infections, being painful, and involving with different organelles. There are different infections of Gram-positive and Gram-negative bacteria in burned patients. From important bacteria can be noted to Pseudomonas aeruginosa, Acinetobacter baumannii, and Staphylococcus aureus that have high range of morbidity and mortality. Treatment of those bacterial infections is extremely important. Hence, many studies about methods of treatment of bacterial infections have published. Herein, we have suggested practical methods for example ant virulence therapies, nanotechnology, vaccine, and photodynamic therapy in treatment of bacterial infections. Those methods have been done in many researches and had good effect.

Implications on hypnotherapy: Neuroplasticity, epigenetics and pain

We provide a brief review about the significance of hypnosis with respect to applications and physiological processes in hypnotherapy. Our review concludes that hypnosis is a promising method to manage acute and chronic pain. In addition, we discuss indications pointing toward the view that hypnosis can induce changes in neuroplasticity possibly involving epigenetic mechanisms.

American Burn Association Guidelines on the Management of Acute Pain in the Adult Burn Patient: A Review of the Literature, a Compilation of Expert Opinion, and Next Steps

The ABA pain guidelines were developed 14 years ago and have not been revised despite evolution in the practice of burn care. A sub-committee of the American Burn Association's Committee on the Organization and Delivery of Burn Care was created to revise the adult pain guidelines. A MEDLINE search of English-language publications from 1968 to 2018 was conducted using the keywords "burn pain," "treatment," and "assessment." Selected references were also used from the greater pain literature. Studies were graded by two members of the committee using Oxford Centre for Evidence-based Medicine-Levels of Evidence. We then met as a group to determine expert consensus on a variety of topics related to treating pain in burn patients. Finally, we assessed gaps in the current knowledge and determined research questions that would aid in providing better recommendations for optimal pain management of the burn patient. The literature search produced 189 papers, 95 were found to be relevant to the assessment and treatment of burn pain. From the greater pain literature 151 references were included, totaling 246 papers being analyzed. Following this literature review, a meeting to establish expert consensus was held and 20 guidelines established in the areas of pain assessment, opioid medications, nonopioid medications, regional anesthesia, and nonpharmacologic treatments. There is increasing research on pain management modalities, but available studies are inadequate to create a true standard of care. We call for more burn specific research into modalities for burn pain control as well as research on multimodal pain control.

Using fibrin sealant for skin graft fixation to avoid sedation in children with burns: a prospective study

OBJECTIVE

To investigate whether a fibrin sealant, Fitrix (Sanquin Blood Supply Foundation, The Netherlands), for fixation of skin grafts in children with burn wounds is less invasive and equally effective in comparison with skin staples.

METHOD

A single-centre prospective observational cohort study was conducted. Children requiring skin grafting after burns were included and received the fibrin sealant. This group was compared with a retrospective control group of children whose skin grafts were fixed with skin staples. Study outcomes were graft take, graft dislocation, other wound complications, healing and need for sedation.

RESULTS

In the fibrin sealant and the control groups, 17 and 27 patients were included, respectively. The percentage of total body surface area (%TBSA) grafted was smaller (p=0.028) in the fibrin sealant group (median 1.0, interquartile range (IQR) 1.5 versus 2.0, IQR 2.5). There was no significant difference in graft take or wound healing. There were two graft dislocations in the fibrin sealant group and none in the control group. Other complications included a patient with graft failure in the fibrin sealant group, and another patient with a vanishing graft and wound infection in the control group. There were fewer sedations in the fibrin sealant group compared with the control group (one versus 20, p<0.0001).

CONCLUSION

The fibrin sealant used in this study was non-inferior for the fixation of skin grafts in comparison with skin staples, and avoided sedation procedures.

Challenges in anaesthesia and pain management for burn injuries

Burn-injured patients provide unique challenges to those providing anaesthesia and pain management. This review aims to update both the regular burn anaesthetist and the anaesthetist only occasionally involved with burn patients in emergency settings. It addresses some aspects of care that are perhaps contentious in terms of airway management, fluid resuscitation, transfusion practices and pharmacology. Recognition of pain management failures and the lack of mechanism-specific analgesics are discussed along with the opioid crisis as it relates to burns and nonpharmacological methods in the management of distressed patients.

The Effectiveness of Group-based Cognitive Hypnotherapy on the Psychological Well-being of Patients with Multiple Sclerosis: A Randomized Clinical Trial

Multiple sclerosis is a chronic, demyelinating disease of the central nervous system mainly affecting young adults. In addition to physical problems, the patients suffer from many psychological problems affecting their psychological well-being. The aim of the present study was to determine the effectiveness of group-based cognitive hypnotherapy on the psychological well-being of patients suffering from multiple sclerosis. This study was designed as a clinical trial with a pretest-posttest control group. From 60 patients diagnosed with multiple sclerosis referred to Beheshti hospital in Yasuj, Iran, 45 patients who met the inclusion criteria were selected by the convenience sampling method. The patients were randomly assigned to intervention (23 individuals) and control (22 individuals) groups through stratified random allocation. After completing the Ryff Scales of Psychological Well-Being, the intervention group attended eight sessions of group-based cognitive hypnotherapy on a weekly basis. The control group did not attend any intervention sessions. At the end of the eight intervention sessions, both groups completed the Ryff's Scale of Psychological Well-being again. The collected data were analyzed using the SPSS software (Version 23). Analysis of Covariance (ANCOVA) and two-way Analysis of variance (ANOVA) tests were used in order to compare the groups. The results indicated that cognitive hypnotherapy had a significant effect on the total score of psychological well-being (F (45, 1) = 6.07, p = .018, η2 = 0.12) and the dimension of environmental mastery (p < .05). Therefore, it is recommended to use hypnotherapy to promote the psychological well-being of patients suffering from multiple sclerosis.

A Review of Adjunctive Therapies for Burn Injury Pain During the Opioid Crisis

Opioids are the mainstay of pain management after burn injury. The United States currently faces an epidemic of opioid overuse and abuse, while simultaneously experiencing a nationwide shortage of intravenous narcotics. Adjunctive pain management therapies must be sought and utilized to reduce the use of opioids in burn care to prevent the long-term negative effects of these medications and to minimize the dependence on opioids for analgesia. The purpose of this review was to identify literature on adjunctive pain management therapies that have been demonstrated to reduce pain severity or opioid consumption in adult burn patients. Three databases were searched for prospective studies, randomized controlled trials, and systematic reviews that evaluated adjunctive pain management strategies published between 2008 and 2019 in adult burn patients. Forty-six studies were analyzed, including 24 randomized controlled trials, six crossover trials, and 10 systematic reviews. Various adjunctive pain management therapies showed statistically significant reduction in pain severity. Only one randomized controlled trial on music therapy for acute background pain showed a reduction in opioid use. One cohort study on hypnosis demonstrated reduced opioid use compared with historical controls. We recommend the development of individualized analgesic regimens with the incorporation of adjunctive therapies in order to improve burn pain management in the midst of an abuse crisis and concomitant national opioid shortage.

Efficacy of hypnosis on pain, wound-healing, anxiety, and stress in children with acute burn injuries: a randomized controlled trial

No randomized controlled trial has investigated the efficacy of hypnosis for reducing pain and improving wound-healing in children with burns. This randomized controlled trial aimed to investigate whether hypnosis decreases pain, anxiety, and stress and accelerates wound-healing in children undergoing burn wound procedures. Children (4-16 years) with acute burns presenting for their first dressing change were randomly assigned to a Hypnosis Group who received hypnosis plus standard care or a Standard Care Group who received standard pharmacological and nonpharmacological intervention. Repeated measures of pain intensity, anxiety, stress, and wound-healing were taken at dressing changes until ≥95% wound re-epithelialization. Data for 62 children were analyzed on an intent-to-treat basis using Generalized Estimating Equations (n = 35 Standard Care Group; n = 27 Hypnosis Group). An effect on the primary outcomes of pain and wound healing was not supported {self-reported pain intensity largest Mean Difference [MD] = -0.85 (95% confidence interval [CI]: -1.91 to 0.22), P = 0.12; MD for re-epithelialization = -0.46 [95% CI: -4.27 to 3.35], P = 0.81}. Some support was found for an effect on the secondary outcomes of preprocedural anxiety (MD = -0.80 [95% CI: -1.50 to -0.10], P = 0.03 before the second dressing change) and heart rate as a measure of stress (MD = -15.20 [-27.20 to -3.20], P = 0.01 and MD = -15.39 [-28.25 to -2.53], P = 0.02 before and after the third dressing change). Hypnosis may be effective for decreasing preprocedural anxiety and heart rate in children undergoing repeated pediatric wound care procedures but not for reducing pain intensity or accelerating wound healing.

Systematic review of clinical outcome reporting in randomised controlled trials of burn care

INTRODUCTION

Systematic reviews collate trial data to provide evidence to support clinical decision-making. For effective synthesis, there must be consistency in outcome reporting. There is no agreed set of outcomes for reporting the effect of burn care interventions. Issues with outcome reporting have been identified, although not systematically investigated. This study gathers empirical evidence on any variation in outcome reporting and assesses the need for a core outcome set for burn care research.

METHODS

Electronic searches of four search engines were undertaken from January 2012 to December 2016 for randomised controlled trials (RCTs), using medical subject headings and free text terms including 'burn', 'scald' 'thermal injury' and 'RCT'. Two authors independently screened papers, extracted outcomes verbatim and recorded the timing of outcome measurement. Duplicate outcomes (exact wording ± different spelling), similar outcomes (albumin in blood, serum albumin) and identical outcomes measured at different times were removed. Variation in outcome reporting was determined by assessing the number of unique outcomes reported across all included trials. Outcomes were classified into domains. Bias was reduced using five researchers and a patient working independently and together.

RESULTS

147 trials were included, of which 127 (86.4%) were RCTs, 13 (8.8%) pilot studies and 7 (4.8%) RCT protocols. 1494 verbatim clinical outcomes were reported; 955 were unique. 76.8% of outcomes were measured within 6 months of injury. Commonly reported outcomes were defined differently. Numbers of unique outcomes per trial varied from one to 37 (median 9; IQR 5,13). No single outcome was reported across all studies demonstrating inconsistency of reporting. Outcomes were classified into 54 domains. Numbers of outcomes per domain ranged from 1 to 166 (median 11; IQR 3,24).

CONCLUSIONS

This review has demonstrated heterogeneity in outcome reporting in burn care research which will hinder amalgamation of study data. We recommend the development of a Core Outcome Set.

Investigation on the Neural Mechanism of Hypnosis-Based Respiratory Control Using Functional MRI

Respiratory control is essential for treatment effect of radiotherapy due to the high dose, especially for thoracic-abdomen tumor, such as lung and liver tumors. As a noninvasive and comfortable way of respiratory control, hypnosis has been proven effective as a psychological technology in clinical therapy. In this study, the neural control mechanism of hypnosis for respiration was investigated by using functional magnetic resonance imaging (fMRI). Altered spontaneous brain activity as well as neural correlation of respiratory motion was detected for eight healthy subjects in normal state (NS) and hypnosis state (HS) guided by a hypnotist. Reduced respiratory amplitude was observed in HS (mean ± SD: 14.23 ± 3.40 mm in NS, 12.79 ± 2.49 mm in HS, p=0.0350), with mean amplitude deduction of 9.2%. Interstate difference of neural activity showed activations in the visual cortex and cerebellum, while deactivations in the prefrontal cortex and precuneus/posterior cingulate cortex (PCu/PCC) in HS. Within these regions, negative correlations of neural activity and respiratory motion were observed in visual cortex in HS. Moreover, in HS, voxel-wise neural correlations of respiratory amplitude demonstrated positive correlations in cerebellum anterior lobe and insula, while negative correlations were shown in the prefrontal cortex and sensorimotor area. These findings reveal the involvement of cognitive, executive control, and sensorimotor processing in the control mechanisms of hypnosis for respiration, and shed new light on hypnosis performance in interaction of psychology, physiology, and cognitive neuroscience.

A Pragmatic Guide to the Setting up of Integrated Hypnotherapy Services in Primary Care and Clinical Settings

Despite the continued debate and lack of a clear consensus about the true nature of the hypnotic phenomenon, hypnosis is increasingly being utilized successfully in many medical, health, and psychological spheres as a research method, motivational tool, and therapeutic modality. Significantly, however, although hypnotherapy is widely advertised, advocated, and employed in the private medical arena for the management and treatment of many physical and emotional disorders, too little appears to be being done to integrate hypnosis into primary care and national health medical services. This article discusses some of the reasons for the apparent reluctance of medical and scientific health professionals to consider incorporating hypnosis into their medical practice, including the practical problems inherent in using hypnosis in a medical context and some possible solutions.

Cryopreserved cultured epithelial allografts for pediatric deep partial dermal burns: Early wound closure and suppression of scarring

BACKGROUND

In deep partial thickness dermal burns (DDB) where greater than 50% of the dermis is lost, severe pain, scarring and contractures occur. Therefore, skin grafting may be required. In children, scar contracture occurs because scarred skin does not stretch with growth creating the need for additional scar-releasing or skin-grafting surgeries. In order to resolve this problem, we used cryopreserved cultured epithelial allograft (cryopreserved allo-CEG), which can be grafted shortly after sustaining a wound. We reevaluated the promotion of early wound closure of burns and suppression of scarring by this treatment.

METHODS

Cryopreserved allo-CEGs were used to treat 50 cases of pediatric DDB from 1992 to 2000. These cases were reviewed with regard to the time until epithelialization, take percentage, and pain level. Also, in order to examine why cryopreserved allo-CEG promotes healing of burns and suppresses scarring, growth factors and cytokines in the cryopreserved allo-CEG were measured. Cryopreserved allo-CEG sheets were solubilized and concentrations of TGF-α, TGF-β1, IL-1α, IL-1β, PDGF-AA, VEGF, KGF, IL-6, b-FGF, as well as metalloprotease-1 (MMP-1) and HGF, which are noted to have scarring suppression effects, were measured before grafting.

RESULTS

Grafting of cryopreserved allo-CEGs in 50 cases of childhood DDB resulted in early epithelialization (9.32 ± 3.63 days on the average) and an almost 100% take rate. Also, pain relief (pain reduction or elimination, reduced need for anesthetics) was seen in all cases. Although 15-23 years have now elapsed, adverse events have not been observed. Cryopreserved allo-CEG contains IL-1α, IL-1β, PDGF-AA, TGF-α, TGF-β1, VEGF, and IL-6 have wound healing effects. The concentration of IL-1α was higher than the concentrations of other components, and this was followed by TGF-α, TGF-β1, b-FGF and VEGF. Although the concentration of MMP-1, which has a scarring suppression effect, was high, HGF was not detected.

CONCLUSION

Cryopreserved allo-CEG contains growth factors that promote wound healing and factors that suppress scarring. Three effects, namely (1) early wound closure, (2) scarring suppression, and (3) pain relief were seen with grafts of cryopreserved allo-CEG in cases of childhood DDB. These observations show that cryopreserved allo-CEG is clinically useful and effective for the treatment of childhood DDB.

[Features of skin graft in pediatric plastic surgery]

Skin graft is a skin tissue fragment transferred from a donor site to a receiving site with a spontaneous revascularization. Basic process of plastic surgery, skin graft known in children, specific, warnings and refinements. It finds its indication in many pediatric cases: integumental diseases (neavus, hamartoma), acute burns and scars, traumatic loss of substance or surgically induced, congenital malformations of the hands and feet, etc. Specific skin graft techniques in children are developed: donor sites, sampling technique and procedure, early postoperative care. Especially in children, the scalp is a perfect site for split skin graft and technique is actively developed. Refinements and special cases are discussed: use of dermal matrices, allografts, xenografts, negative pressure therapy, prior skin expansion of the donor site. Results of skin graft in children are exposed: taking of graft, growth and shrinkage, pigmentation. Skin graft sometimes allows to stay the complex movement and get the best final benefit, permanent or at least temporary, in a growing being.
