This study demonstrates the possibilities of laser thermoplasty of whole costal cartilages for treatment of human congenital chest wall deformities. The development of novel approaches based on laser cartilage engineering techniques will enable to treat the human congenital chest wall deformities.

Capillary angiodysplasia of the skin presents by itself pathologically dilated capillaries located under the basal zone of the growth of the epidermis. There are many options for the correction of this vascular pathology of the skin, including general and local methods. In recent years, laser treatments for capillary angiodysplasia have become widespread. According to many authors, the most effective and promising method is laser photodestruction by radiation of the yellow-green spectral range. Unfortunately, the optimal ranges of the parameters of exposure to laser radiation in the treatment of specific forms of capillary angiodysplasia of the skin, taking into account nature and age characteristics of the skin in children, have not yet been determined.

Introduction. Testicular torsion is an emergency condition requiring emergency medical care. Polymorphism of symptoms in testicular torsion makes diagnostics not easy and leads to late treatment what can results in irreversible damages to the testicle. Early diagnostics is a key point to organ preservation. Material and methods. The authors describe two clinical cases of testicular torsion in adolescents with errors in diagnostics. Clinical, laboratory findings and instrumental examination (MRI, ultrasound) were used for diagnostics. Results. A diagnostic error resulted in orchectomy which was made to one patient. In the other patient - despite a diagnostic error- testiclular detorsion and urgent surgical intervention resulted in patient’s complete recovery. Discussion. These examples illustrate how important is to carefully study the patient’s case-history - onset and nature of pain, associated vegetative symptoms - nausea and vomiting - which are not characteristic for other acute testicular diseases. Conventional tactics of urgent surgical intervention for all acute testicular diseases in children does not insure against diagnostic errors in case of testicular torsion with atypical symptoms. Ultrasound examination is of irreplaceable value, but one cannot be guided only by its findings in excluding testicular torsion. Conclusion. Any of the symptoms of testicular torsion - whether it is acute onset or severe pain, or a combination with vomiting, or severe pain on palpation, or ultrasound findings - is a reason to suspect testicular torsion and, it is an absolute indication for urgent surgery. The protocol for diagnostics and treatment of acute testicular diseases developed by us includes these diagnostic peculiarities and allows to choose an effective treatment modality.

Introduction. Despite the modern development of surgery complications and relapses after the surgical treatment of children with a pathology of the vaginal process of the peritoneum continue to occur in the practice of the pediatric surgeon. The aim is to determine the causes of complications and relapses after the surgical treatment of children with the pathology of obliteration of the vaginal process of the peritoneum. Material and methods. The article presents the results of surgical treatment of 1818 children with the pathology of the vaginal process of the peritoneum, including 32 children with complications and relapses occurred after surgical interventions. Two clinical observations of children of 10 and 14 years were operated on for recurrence of an inguinal hernia and hydrocele are described. Results. The frequency of relapses or complications in the Research Institute of Emergency Pediatric Surgery and Traumatology after surgical treatment of children with inguinal hernias, hydrocele and cryptorchidism ranged from 1.5% to 2.3%. Conclusions. Non-adherence to surgical treatment causes recurrences and complications.

Introduction. Pyogenic granuloma (PG), a benign vascular tumor of the skin of inflammatory etiology, is often met in children. Complications of this pathology (ulceration and bleeding) are seen in 7.5% of cases. Material and methods. 67 patients were operated on for pyogenic granulomas. 22 patients had bleedings. Before surgery, all patients had sonography with color Doppler mapping of this vascular formation. 57 children had a planned surgery and were operated under topical anesthesia in the outpatient unit. 10 patients on admission had bleedings from pyogenic granulomas. After conservative arresting the bleeding, 7 patients out of these 10 had urgent surgery; in other three children with severe bleeding hemostasis was not achieved conservatively, and they were immediately operated on. All urgent surgical interventions were made under local anesthesia in an outpatient operating room. Patients with emergency cases, were younger than 3 y.o. They were operated in the operation room in the hospital under general anesthesia. Pyogenic granulomas in all 67 patients were removed by the technique of interstitial selective laser photodestruction, the prototype of which was “Method for treating cavernous forms of hemangiomas in children” developed and patented in CRIEPST. For this surgical intervention, two-wave laser surgical device “IRE-Polyus” (Russia), with wavelength of 0.97 mkm and 1.56 mkm was used. Results. Postoperative period in all patients was uneventful, with complete healing of wound defect in 10-12 days; no recurrences of vascular formation or its residual elements were observed in any case. All 67 patients had good clinical and aesthetic results after the applied surgical technique. Conclusion. To prevent complications in children with pyogenic granulomas, surgical treatment with the technique of interstitial selective laser photodestruction adapted for this pathology is recommended. The described interstitial selective laser photodestruction radically removes pathological tissues of pyogenic granulomas and ensures reliable hemostasis, what leads to good clinical and aesthetic results in treating the discussed group of patients both in inpatient and outpatient settings.
