Purpose: The aim of this neurophysiological study was to retrospectively analyze visual evoked potentials (VEPs) acquired during an examination for diagnosing optic nerve involvement in patients with Lyme neuroborreliosis (LNB). Attention was focused on LNB patients with peripheral facial palsy (PFP) and optic nerve involvement.
Methods: A total of 241 Czech patients were classified as having probable/definite LNB (193/48); of these, 57 were younger than 40 years, with a median age of 26.
Despite positive prior results obtained by using event-related potentials (ERPs) in psychiatric patients, they are not routinely used in the clinical setting. This may in part be due to problems regarding a lack of transportable equipment availability. It can be difficult for these patients to repeatedly visit electrophysiological laboratories.

- Patients with chronic lymphocytic leukemia (CLL) have a significantly heightened risk of developing other malignancies (OMs), with a study tracking nearly 20,000 CLL patients revealing 3,513 OMs diagnosed over 129,254 years of follow-up.
- The study found that treatment with fludarabine and cyclophosphamide increased the likelihood of developing myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML), while non-melanoma skin cancer (NMSC) and prostate cancer were common solid tumors in treated patients.
- Importantly, patients with CLL who developed OMs had lower overall survival rates, especially those diagnosed with AML and MDS, highlighting that C
Introduction: We developed a new portable device called "VEPpeak" for the examination of visual evoked potentials (VEPs) to extend VEP examination beyond specialized electrophysiological laboratories and to simplify the use of this objective, noninvasive, and low-cost method for diagnostics of visual and central nervous system dysfunctions.
Methods: VEPpeak consists of a plastic headset with a total weight of 390 g containing four EEG amplifiers, an A/D converter, a control unit, and a visual LED stimulator built in the front, vertically adjustable peak. The device is powered and controlled via USB connection from a standard PC/notebook using custom software for visual stimuli generation and for VEP recording and processing.
