The new method presented in this study was directly based on the consideration that ophthalmic arterial Doppler signals are chaotic signals. This consideration was tested successfully using the nonlinear dynamics tools, like the computation of Lyapunov exponents. Multilayer perceptron neural network (MLPNN) architecture was formulated and used as a basis for determining variabilities such as st...

the skin hyperreactivity, detected by the pathergy test, is a well known phenomenon in behcet's disease. two different methods were used for the pathergy test. a) a needle prick, b) an intadermal injection of normal saline. in this study 83% of behcet's patients had a positive pathergy test. where as 44% was of pustule type and 39% of papule type. in 26% of patients the papule formati...

behcet´s disease (bd) is accepted as a systemic vasculitis. vasculitis is observed  predominantly on the venous system. vessel involvement is frequently seen in males. this study was planned retrospectively evaluate demographic features, clinical features, vessel involvements in bd. furthermore, we aimed to prospectively compare consecutively chosen patients with and without thrombosis and heal...

a 33-year-old female-a known case of behcet's disease- was admitted to the hospital due to fever, dyspnea and hemoptysis. one week before admission, she had developed right leg swelling. the history suggested either deep vein thrombosis (dvt) and pulmonary emboli or pulmonary artery vasculitis. diagnostic tests were requested and the necessary treatment was started accordingly

Behcet’s disease is a multisystem inflammatory disorder of unknown origin, characterized by recurrent oral and genital ulcerations, ocular and cutaneous lesions, arthritis, central nervous system and vascular disease. There is no pathognomanic laboratory test, but there are clinical criteria to assist in establishing the diagnosis. There are only a few study about the laryngeal manifestation of...
