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.

Introduction. Hemangiomas in infants at their first weeks of life can quickly progress and lead not only to the disfigurement of appearance, but also to serious complications, like bleeding, ulceration, suppuration and other negative consequences. Purpose. To have good clinical and aesthetic results in children with cavernous hemangiomas using the technique of interstitial selective laser photodestruction. Material and methods. In 2016 - 2018, focal forms of hemangiomas were registered in 140 children aged 1 month-16 years who were consulted in the Clinical and Research Institute of Emergency Pediatric Surgery and Trauma. The technique of interstitial selective laser photodestruction was selected for surgical treatment in all patients (RF Patent №2016110843 dated 04.09.2017). Two-wave laser surgical apparatus LSP IRE-Polyus (Russia) with wavelengths 0.97 μm and 1.56 μm was used. All 140 patients had ultrasound examination of their vascular formations and other preoperative procedures . The surgical intervention was performed in the hospital under general anesthesia. 131 of patients had planned operations and 9 of them had urgent operations because of hemangioma bleeding. Results. Long-term outcomes have shown that in 100% of cases we achieved good clinical result with no residual hemangioma elements; in the majority of cases (69%) the optimal aesthetic result was achieved; and in 31% of cases we had satisfactory outcomes by the criteria of aesthetic effectiveness. Conclusions. Interstitial selective laser photodestruction is the best option to radically treat focal forms of hemangiomas in children.

Статья посвящена описанию эколого-туристского потенциала штата Западная Австралия. В качестве ресурсов экотуризма рассматриваются уникальные природные особенности штата и многочисленные охраняемые природные территории международного, государственного и регионального уровня. Информация для анализа взята из официальных источников австралийского правительства и соответствующего департамента изучаемого штата. The article is devoted to the description of the ecological and tourist potential of the state of Western Australia. The unique natural features of the state and numerous protected natural areas at the international, state and regional levels are considered as ecotourism resources. The information for the analysis is taken from official sources of the Australian government and the relevant department of the state under study.

Кратко описана классификация охраняемых природных территорий (ОПТ), предложенная в 1994 г. Международным Союзом Охраны Природы (МСОП). Особое внимание уделено положительному опыту использования категорий МСОП на Австралийском континенте. Проведено сопоставление многочисленных региональных названий ОПТ Австралии и классификационных категорий МСОП. В основе сравнения лежали принципы управления и характер использования охраняемой природной территорией. В таблицах приведены современные исходные данные и количественные результаты сравнительного анализа. The classification of protected areas (TAS), proposed in 1994 by the International Union for Conservation of Nature (IUCN), is briefly described. Particular attention is paid to the positive experience of using IUCN categories on the Australian continent. A comparison of the numerous regional names of the Protected Areas of Australia and the IUCN classification categories was carried out. The comparison was based on the principles of management and the nature of the use of the protected natural area. The tables provide modern initial data and quantitative results of comparative analysis.
