Some amounts of ultraviolet radiation are beneficial for humans but excessive exposure can cause many negative health effects to the skin and eyes and also can affect the immune system. Exposed area of skin should be covered by working clothes with low UVR transmission. It concerns both exposure to natural UV or prolonged exposure to artificial UV. This(More)
PURPOSE To quantify the maximal level of temperature and the time the maximal temperature is achieved and correlate the temperature parameters to the mean rate of endothelial cell loss after standardized ultrasound delivery assisted with four viscoelastic substances or different temperature of balanced salt solution (BSS). METHODS Thirty rabbits (60 eyes)(More)
Ophthalmic viscoelastic devices play a crucial role in cataract surgery today by protecting corneal endothelium, structures of anterior chamber and maintaining space inside the eye for safe manipulation during surgical treatment. Many factors likely affect the corneal endothelium during phacoemulsification procedure. These can be divided into 3 groups: 1.(More)
This paper presents a study of the possibilities of evaluating thermal parameters of single and multilayer structures using dynamic thermography. It also discusses potential uses of lock-in thermography. It presents a simulation of a periodic excitation of a multilayer composite material. In practice, the described methods can be employed in various(More)
Psoriasis vulgaris is a chronic inflammatory skin disease with a strong genetic component, characterized by hyperkeratosis, dermal inflammatory infiltrate and increased angiogenesis. The aim of the present study was to employ thermography in evaluation of psoriatic lesions localized in different parts of the body. A series of in-patients with stable plaque(More)
PURPOSE To measure the temperature parameters on the corneal surface during the delivery of standardized ultrasound energy assisted with ophthalmic viscosurgical devices (OVDs) or different temperatures of irrigating solutions in an experimental animal model. SETTING Department of Ophthalmology and Visual Rehabilitation, Medical University of Lodz, and(More)
Psoriasis vulgaris affects about 2% of the human population all over the world. The aim of this study was to evaluate usefulness of thermography in estimation of psoriatic lesion activity. A series of patients with plaque type psoriasis vulgaris were included. ThermaCam INFRAMETRICS 290E thermocamera with temperature resolution of 0.1 degrees C was(More)
PURPOSE The aim of the study was to analyze early effects and toxicity of salvage high dose rate brachytherapy for local recurrences of adenocarcinoma of the prostate after external beam radiotherapy (EBRT). MATERIAL AND METHODS In MCS Memorial Institute of Oncology in Gliwice a research programme on salvage HDR brachytherapy for local recurrences of(More)
Congenital optic disc pit is a rare finding that develops from incomplete closure of the embryonic choroid fissure. Maculopathy is a major cause of visual deterioration. The treatment of the macular detachments associated with congenital optic disc pits remains controversial however it is emphasized that rerouting fluid from subretinal space may be(More)
Psoriasis vulgaris is a chronic inflammatory skin disease characterized by hyperkeratosis, dermal inflammatory infiltrate and increased angiogenesis. The aim of the present study was to assess usefulness of thermography in psoriatic lesion regression. Ten in-patients with psoriasis vulgaris were included in the study.
