Treatment of basal cell cancer in the periorbital area using a pulsed copper vapour laser

An increase in life expectancy in developed countries is inevitably accompanied by an increase in the number of nonmelanoma skin diseases, which are primarily represented by basal cell cancer (BCC) occurring in elderly and old-age patients. The pathogenesis of such diseases is associated both with impaired proliferation and differentiation of the keratinocytes of the epidermal basal layer, as well as with the transformation of the vasculature in the papillary dermis in the vicinity of BCC. In recent years, such conditions have been increasingly treated using CO2 , neodymium, diode and pulsed-dye lasers. In many cases, these devices allow malignant BCC cells to be successfully eliminated. However, the use of near-infrared lasers in the periorbital area is limited due to a higher risk of damaging the organs of the visual system. Therefore, a search for new laser surgery methods that can be used for treating malignant skin tumours seems to be a prospective research direction.Methods. 3 male and 9 female patients diagnosed with primary BCC were treated using a copper vapour laser (Yakhroma-Med). The age of the patients varied from 34 to 77 years. Laser treatment was carried out in one session under the following irradiation parameters: the wavelength of 511 and 578 nm, the average power of up to 3 W and a series of 15 ns pulses. The pause between the pulses was 60 μs, with the exposure time ranging from 200 to 600 ms. The light spot diameter on the skin surface was 1 mm. The follow-up monitoring duration was 24 months.Results. In all the BCC patients, one session of copper vapour laser treatment allowed malignant cells in the disease area to be completely eliminated without relapses during 2 years after the therapy. The duration of skin healing in the irradiated area was 2 weeks in patients under the age of 40 years, compared to 3–4 weeks in elderly patients. After the treatment, short-term side effects, such as a slight edema, erythema and peeling, were observed

Клинические наблюдения гигантоклеточного гепатита у детей

Giant cell hepatitis is characterized, by inflammation and large multinucleated. hepatocytes in hepatic parenchyma It is an unusual hepatocytes response to various noxious stimuli, characterized, by presence of multinucleated cells in liver with generally dismal clinical outcome. Giant cell hepatitis is commonly reported, in neonatal and. infantile liver diseases but rarely in adults (postinfantile giant cell hepatitis). Giant cell hepatitis is associated, with many diseases, including drugs toxicity, viral and. autoimmune liver diseases, with autoimmune hepatitis being the most prevalent. We report some clinical cases of giant cell hepatitis with review of literature regarding various etiological agents and their respective prognostic outcome.Гигантоклеточный гепатит, характеризуется наличием воспалительного инфильтрата и гигантских многоядерных клеток в печеночной паренхиме. Гигантоклеточная трансформация представляет, собой необычный ответ, гепатоцитов на различные повреждающие факторы, обычно с неблагоприятным, клиническим, исходом. Гигантоклеточный гепатит, обычно наблюдается при неонатальных и инфантильных заболеваниях печени и редко у взрослых (постинфантильный гигантоклеточный гепатит). Гигантоклеточный гепатит, ассоциируется со многими заболеваниями, включая токсическое воздействие лекарственных средств, вирусные и аутоиммунные заболевания печени. Наиболее распространенным, является аутоиммунный гепатит. Мы сообщаем, о нескольких клинических случаях гигантоклеточного гепатита с обзором, литературы, относительно различных этиологических агентов и их соответствующих прогностических результатов

VENOUS ECTASIA OF THE VERMILION BORDER: COPPER VAPOR LASER TREATMENT

We present the experience of application of "Yakhroma-Med" copper vapor laser system for the treatment of venouse ectasia (VE) of the vermilion border. The yellow wavelength of the generated laser radiation reaches 578 nm falls at the peak of hemoglobin absorption. The treatment was conducted in 58 patients with VE rising above the skin for no more than 1 mm. 100% clinical result. With a hemangioma size of up to 1 cm, treatment efficiency was 87% after the first procedure and complete resolution in 13% of the patients after the second procedure. At a size of more than 1 cm, the efficiency was 71% after the first procedure and 29% after the second. A 100% clinical result was obtained. The therapeutic effect persisted throughout the year in all 58 patients. It has been established that microcirculation disorders processes and further development of VE are affected by a variety of exogenous factors: about a half (48.3%) of the patients were deliberately subjected to excessive sunlight exposure, more than a quarter lived in regions with adverse climatic factors (wind, cold, abnormally low humidity, etc.) (27.6%), or regularly received hyperthermic procedures (steam bath, sauna, etc.) (25.9%). A burn (thermal, chemical) is found in the medical history of one in every five women (20.7%). 17.2% of the patients indulged in excessive consumption of condimental, spicy and hot food
