Silicones in the rehabilitation of burns: a review and overview

This article gives an overview of the use of silicones in the treatment and prevention of hypertrophic (burn related) scars. Of all non-invasive treatment modalities the use of continuous pressure and occlusive contact media, e.g. silicones, seem to be generally accepted as the only ones that are able to manage hypertrophic scarring without significant side-effects. A summary of the current opinions of the assumed working mechanisms of pressure as well as silicones is given. The use of silicones, either alone or in combination with pressure, is discussed. The recent development of custom made silicone devices has led to combinations of both modalities. Some of these, including the inflatable silicone insert systems (ISIS), are shown and discussed.

The effect of triclosan-coated sutures in wound healing. A double blind randomised prospective pilot study

BACKGROUND Wound infection and dehiscence are both major contributors to postoperative morbidity. One potential cause or co-factor is the use of suture material. A recently introduced subcutaneous suture is coated with triclosan (TC), an antiseptic drug. It is suggested to reduce wound complications. METHODS To investigate the effect of TC on wound healing a double blind prospective pilot study in women undergoing a breast reduction was performed. Each patient was her own control. After randomisation the TC-coated sutures were used either on the left or right side. The contralateral side was used as the control. The incidence of dehiscence was studied. RESULTS Twenty-six patients were included. In the TC breasts there was a wound dehiscence in 16 cases, whereas in the control breasts in seven cases a dehiscence was observed (P=0.023). CONCLUSION These results suggest that TC-coated sutures should be used with caution. These sutures have already been introduced on to the market without good clinical studies and might have potential adverse effects as shown by these data.

The effects of conservative treatments on burn scars: a systematic review

A variety of conservative treatments for burn scars are available, but there is no clear consensus on the evidence. The purpose of this study was to summarize the available literature on the effects of conservative treatments of burn scars in adults. RCTs and CCTs were sought in three databases, reference lists of retrieved articles and relevant reviews. The Scottish Intercollegiate Guidelines Network scoring system was used to assess the quality of the selected studies. Information on the study characteristics, results and interventions was extracted. Twenty-two articles were included into the review and categorized in six topics: 5 on massage therapy, 4 on pressure therapy, 6 on silicone gel application, 3 on combined therapy of pressure and silicone, 3 on hydration and 1 on ultrasound. Pressure and silicone therapy are evidence-based conservative treatments of hypertrophic scar formation after a burn producing clinically relevant improvement of scar thickness, redness and pliability. Massage therapy could have a positive result on scar pliability, pain and pruritus, but with less supporting evidence. The use of moisturizers and lotions could have an effect on itching, but the findings are contradictory. Of all other non-invasive treatments such as splinting, casting, physical activity, exercise and mobilizations no RCTs or CCTs were found.

Reproducibility of repeated measurements on post-burn scars with Dermascan C

The present study investigated the reproducibility of measurements with the Dermascan C on post‐burn scars. Intra‐ and inter‐rater reproducibility and test–retest reliability with a one week time lapse were examined on 40 post‐burn scars of 6 volunteering burn patients by means of intra‐class‐ correlation coefficients (ICC) and standard error of measurements (SEM). Results showed good to excellent values for ICC in all the three conditions.

Measurement of elasticity and transepidermal water loss rate of burn scars with the Dermalab

This cross-sectional study investigated the reproducibility of repeated elasticity and transepidermal water loss (TEWL) measurements with the DermaLab(®) on 32 active burn scars and healthy skin. Intra- and inter-observer reproducibility was examined by means of intra-class correlation coefficients (ICC) and standard error of measurements (SEM). Results showed good ICC values and rather high SEM values for inter- and intra-observer reproducibility of elasticity measurements. For TEWL measurements, ICC values were good and SEM values were high for inter- and intra-observer reproducibility. There was a significant difference between the estimated mean elasticity values of normal skin and grafted scars and between normal skin and spontaneously healed scars (p≤0.003). For the estimated mean TEWL values, there was a significant difference between normal skin and spontaneously healed scars (p=0.036). A significant negative relation was reported between mean TEWL and time after burn (p=0.008). In clinical trials it is necessary to interpret patient-specific changes in elasticity and TEWL with caution, since the SEMs of both modes are rather high. We therefore recommend the use of a mean of repeated measurements of elasticity and TEWL to decrease the SEM.

Initial reconstruction of sustained neck and facial burns.

Approximately 50% of burn injuries involve the neck and head region. Because both appearance and function must be taken into account with burns of this area, several consecutive reconstructions will be performed. With a focus on improving outcome after burn injury, we underline the method of grafting as a very important element in primary surgery. With our special excision and grafting technique, we aim to achieve a reconstruction that deals with mobility and aesthetics. Consequently, necessary reconstructive procedures may be fewer and of less magnitude. We describe this surgical technique in detail. In this study we surgically treated 39 patients with sustained facial and neck burns. For 22 patients this surgical treatment circumvented the need to perform any secondary reconstructions. The proposed treatment involves a special grafting technique after pretreatment with a topical agent in combination with early pressure therapy.

Minimizing limb amputations in meningococcal sepsis by early microsurgical arteriolysis.

PURPOSE Surgical treatment of children with meningococcal sepsis has mainly involved debridement of necrotic skin and amputation of limbs. This resulted in major functional impairment. On the contrary, when early microsurgical arteriolysis was performed, freeing up the blood vessels, the impaired blood flow could be restored, thereby significantly reducing the amputation levels. METHODS We prospectively evaluated 14 patients affected by meningococcal sepsis. In 7 patients, microsurgical arteriolysis was performed; standard sepsis treatment was performed on the remaining 7. Ischemia levels on admission were compared with permanent amputation levels after 1 year. RESULTS Statistically significant decreases (P = .005) in ischemia values were achieved by the arteriolysis, in comparison with final amputation percentages. The functional impairment of the affected limbs was highly reduced compared with the probable loss of function observed on admission. CONCLUSIONS Our findings show that early microsurgical arteriolysis is a reliable method to reduce the devastating amputations normally found in patients with meningococcal sepsis. This significantly improves the functional outcome in severely ischemic limbs in meningococcal induced septic children.

Influence on clinical parameters of depressomassage (part I): The effects of depressomassage on color and transepidermal water loss rate in burn scars: A pilot comparative controlled study

OBJECTIVE Depressomassage is a non-invasive massage technique using a mechanical suction device that is used in the treatment of traumatic or burn scars. Since color and transepidermal water loss (TEWL) are respectively the most important physical and physiological characteristic of hypertrophic scar formation, we wanted to investigate the effects of depressomassage on the recovery of color and TEWL in burn scars compared to the traditional physiotherapy. METHODS In this pilot comparative controlled study a total 43 burn patients were included and allocated into 2 groups. All patients received standard physical therapy, and the test group received additional depressomassage during 6 months. Color was assessed using the POSAS questionnaire (for color, vascularity and pigmentation) and the Minolta Chromameter. TEWL was measured using DermaLab. RESULTS Patients of both groups were evaluated at baseline, after 1, 3 and 6 months and after 1year. The evidence for a difference in evolution of color and TEWL between both groups in our study was minimal. CONCLUSIONS In practice, precise indications to begin depressomassage have to be kept in mind. Perhaps other scar abnormalities such as decreased elasticity, increased thickness, excessive pain or itching could be sufficient reasons to begin depressomassage and should be assessed.
