BACKGROUND: Taking into account the role of angiogenesis processes in the zone of development of immature scar tissue, it seems pathogenetically justified to use a vascular laser for the correction of hypertrophic skin scars that are at the maturation stage. In this regard, we used a pulsed dye laser, the effect of which is perceived by the patient without pronounced pain, and the technology itself is quite safe and leads to a rapid recovery of the skin after the procedure. Fermencol phonophoresis supplementation of laser therapy with pulsed dye laser has the potential to enhance the therapeutic efficacy of a vascular laser, since Fermenkol is a preparation of collagenases of hydrobiont origin that can destroy the components of the extracellular matrix, the formation of which exceeds in intensity its degradation by matrix metalloproteinases at the stage of formation scar. The use of ultrasound in this case not only accelerates the delivery of proteolytic enzymes, but also exhibits independent fibromodulatory activity. AIM: comparative evaluation of the effectiveness of the use of physiotherapeutic factors (Fermenkol phonophoresis, pulsed dye laser therapy and their combination) in patients with immature hypertrophic skin scars, taking into account clinical research methods. MATERIAL AND METHODS: The study was performed on 125 patients aged 19 to 50 years with immature (less than 6 months) hypertrophic skin scars. All patients were divided into 4 groups according to the simple fixed randomization procedure. The first group (control, 32 patients) received course local compression therapy using silicone plates for two months. The second group (31 patients) was treated with phonophoresis of 0.01% Fermencol gel. The third group (31 patients) was treated with pulsed dye laser. The fourth group (31 patients) received complex treatment, including a combination of two pulsed dye laser procedures and two cycles of Fermencol phonophoresis. Patients were examined twice: before the start of treatment and 2 weeks after the end of the course of treatment. The assessment of the clinical condition of patients was carried out according to the modified Vancouver scale for assessing the signs of cicatricial deformity. RESULTS: Conducting a course of treatment of patients with immature hypertrophic skin scars made it possible to establish a good tolerability of the effects of physiotherapeutic factors. At the same time, the positive dynamics of clinical manifestations of cicatricial changes in the skin, assessed by Vancouver scar scale, in the control and main groups was not the same and increased in the following order: Control Fermencol phonophoresis pulsed dye laser pulsed dye laser + Fermencol phonophoresis. The use of the correlation adaptometry technique, which makes it possible to objectify the obtained clinical data, evaluating them using the category of functional reserves of the body, confirmed that the best clinical result was achieved in the group recieved combined use of pulsed dye laser and Fermencol phonophoresis. CONCLUSION: The conclusion was made about the maximum therapeutic effect in the group of complex use of pulsed dye laser and ultrasound administration of an enzyme preparation, which manifested itself due to the synergistic type of interaction between two physiotherapeutic factors that have different modalities, points of application and mechanisms for implementing their therapeutic activity.

Introduction. Infantile hemangiomas (IH) are the most common benign vascular tumor of children of the first year and are an interdisciplinary problem of neonatologists, pediatricians, pediatric cardiologists, oncologists, pediatric surgeons, dermatologists. Depending on the age of child, phase of pathological process, size, and localization of the IH, the management tactics of such children can be conservative (pharmaceuticals therapy) or invasive (laser therapy, surgical methods). Laser therapy with a pulsed dye laser has proven itself well to correct and minimize residual phenomena because of spontaneous involution and after the completion of pharmaceuticals treatment.The purpose of the study is to analyze the experience of using Hemangiol® (oral solution) for the treatment of children with IH, obtained in 10 medical hospitals in 6 cities of Russia.Materials and methods. Treatment with Hemangiol® was carried out in 6 cities of Russia on the basis of 10 medical hospitals (Children’s CityClinical Hospital named after Z.A. Bashlyaeva of Moscow City Health Department, Research Institute of Pediatric Oncology and Hematology of N.N. Blokhin National Medical Research Center of Oncology, Ministry of Health of Russia (Moscow), Russian Children’s Clinical Hospital of the N.I. Pirogov Russian National Research Medical University, Ministry of Health of Russia (Moscow), Children’s City Clinical Hospital named after N.F. Filatov of Moscow City Health Department, Saint Petersburg Clinical Scientific and Practical Center of Specialized Medical Assistance (Oncological) (S.-Petersburg), Almazov National Medical Research Centre, Ministry of Health of Russia (S.-Petersburg), Rostov Regional Clinical Hospital (Rostov-on-Don), Stavropol Regional Children’s Clinical Hospital (Stavropol), Samara Regional Clinical Hospital named after V.D. Seredavin, Children’s Republican Clinical Hospital of the Ministry of Health of the Republic of Tatarstan (Kazan) in the Departments of Pediatric Cardiology, Surgery, Oncology, Pediatrics from January 2020 to December 2021. Therapy with Hemangiol® was received by 49 children with IH for at least 3 months. Before the start of treatment, the patients’ heart rate and blood pressure were measured, general and biochemical blood tests were performed, electrocardiography and ultrasound IH were performed. According to the indications, ultrasound of the liver and thyroid gland was performed to determine the parameters of the thyroid status. Before the start of therapy and during dynamic observation, photo documentation was performed against the background of treatment. In the absence of contraindications to treatment, Hemangiol® was prescribed. During a six-month course of treatment with Hemangiol®, effectiveness was evaluated based on the results of a clinical examination and based on photographs. The appearance of possible adverse reactions was monitored.Results. In 33 (67.3 %) children with IH, therapy with Hemangiol® was completed within 6 months. The effect of treatment in the form of a pronounced regression of vascular tumor was achieved in 25 (75.8 %) of 33 patients. In 16 (32.7 %) of 49 children, treatment with Hemangiol® was continued for more than 6 months. The first symptoms of improvement were observed from the second to 10 days after the start of Hemangiol® therapy in 45 patients, which was (91.8 %). Rebound syndrome (recurrence of IH) was detected in 2 (6.0 %) of 33 children who completed therapy. Transit adverse reactions (decreased heart rate, increased excitability, lethargy) on therapy of Hemangiol® were observed in 8 (16.3 %) children. The duration of therapy with Hemangiol® depended on the prevalence, the depth of the IH lesion, as well as on the presence of prematurity in a child with IH (r = 0.533, p < 0.05). Successful laser treatment with a pulsed laser on a dye after the completion of systemic Hemangiol® therapy, were on 5 children of Research Institute of Pediatric Oncology and Hematology at N.N. Blokhin National Medical Research Centre of Oncology, Ministry of Health of Russia.Conclusion. The results of the using of Hemangiol® as a modern means of systemic pharmacotherapy of IH therapy in 10 medical hospitals in 6 cities of Russia have demonstrated its high efficiency and safety.
The article analyzes the role of matrix metalloproteinases (MMP) in the pathogenesis of immature hypertrophic scars. The revealed decrease in the MMP level in the patients’ initial state against the background of an increased content of TIMP1 indicates a disorder in the mechanisms of regulation of collagen formation in a hypertrophic scar, as a result of which its synthesis significantly predominates over decay, contributing to the formation of a fibrous process. The obtained results convincingly prove that reduced expression of MMP against the background of an increased TIMP1 level is an important pathogenetic mechanism providing excessive deposition of extracellular matrix components in pathological skin scarring. The use of a pulsed dye laser (PDL) in combination with Fermencol phonophoresis promotes an increase in the MMP content in the blood serum of patients with immature hypertrophic scars. The reliable dynamics of the studied biomarkers indicates an increase in the processes of catabolism of the extracellular matrix components and an increase in the regenerative potential of the skin defect, which determine the intensity of the clinical effect during the treatment of immature hypertrophic scars. The correlation analysis between the level of membrane metalloproteinases and the parameters of the Vancouver Scar Scale revealed a set of significant relationships that confirm the clinical and pathogenetic significance of these biochemical variables in the development of fibroplastic processes and also act as informative criteria for the effectiveness of the therapy.
