ABSTRACT
Sneddon syndrome (SS) is rare, arterio-occlusive disorder characterized by generalized livedo racemosa of the skin and various central nervous symptoms due to occlusion of medium-sized arteries of unknown. Seizure, cognitive impairment, hypertension, and history of repetitive miscarriages are the other symptoms seen in this disease. Livedo racemosa involves persisting irreversible skin lesions red or blue in color with irregular margins. Usually, SS occurs in women of childbearing age. Protein S deficiency is an inherited or acquired disorder associated with an increased risk of thrombosis. We present a 33-year-old woman with SS with diffuse livedo racemosa, recurrent cerebrovascular diseases, migraine-type headache, sinus vein thrombosis, and protein S deficiency. Protein S deficiency and with Sneddon syndrome rarely encountered in the literature.
ABSTRACT
Four children with vincristine (VCR)-induced neuropathy are being reported. All cases were followed with the diagnosis of acute lymphoblastic leukemia. Two were boys aged between 2 and 13 year. Electromyographic examination consisted of sensoriomotor polyneuropathy with axonal involvement in three patients. In another patient, it consisted of motor axonal polyneuropathy. In all patients, pyridoxine and pyridostigmine were successfully used in the treatment of VCR-induced neuropathy. They recovered completely with this drug combination. Recovering period of symptoms was between 1-2 week.
