Auditory Brainstem Response in Patients with Tinnitus Associated with Vitamin B12 Deficiency.

Unlabelled: Abtract Objective: The auditory brainstem response (ABR) has been reported as normal in patients with vitamin B12 deficiency, but there have also been reported cases of interference in amplitude responses. However, studies investigating the effects of vitamin B12 on auditory response are limited in patients with tinnitus. The aim of this study was to investigate the ABR findings in patients with tinnitus together with vitamin B12 deficiency.

Evaluation of cytokines as Th1/Th2 markers in pathogenesis of children with Crimean-Congo hemorrhagic fever.

Cytokine networks play a key role in the pathogenesis of the disease in Crimean-Congo Hemorrhagic Fever (CCHF) patients. Therefore, our aim was to study the effects of cytokine levels on the pathogenesis and severity of the disease in children with CCHF. Fifty-two patients diagnosed with CCHF and 34 healthy controls (HC) were included in the study.
