Background and purpose:
Ciprofloxacin (CIP) is a broad-spectrum antibiotic widely used in clinical practice to treat musculoskeletal infections. Fluoroquinolone-induced neurotoxic adverse events have been reported in a few case reports, all the preclinical studies on its neuropsychiatric side effects involved only healthy animals. This study firstly investigated the behavioral effects of CIP in an osteoarthritis rat model with joint destruction and pain, which can simulate inflammation-associated musculoskeletal pain. Furthermore, effects of CIP on regional brain-derived neurotrophic factor (BDNF) expression were examined given its major contributions to the neuromodulation and plasticity underlying behavior and cognition.
.
Methods:
Fourteen days after induction of chronic osteoarthritis, animals were administered vehicle, 33 mg/kg or 100 mg/kg CIP for five days intraperitoneally. Motor activity, behavioral motivation, and psychomotor learning were examined in a reward-based behavioral test (Ambitus) on Day 4 and sensorimotor gating by the prepulse inhibition test on Day 5. Thereafter, the prolonged BDNF mRNA and protein expression levels were measured in the hippocampus and the prefrontal cortex.
.
Results:
CIP dose-dependently reduced both locomotion and reward-motivated exploratory activity, accompanied with impaired learning ability. In contrast, there were no significant differences in startle reflex and sensory gating among treatment groups; however, CIP treatment reduced motor activity of the animals in this test, too. These alterations were associated with reduced BDNF mRNA and protein expression levels in the hippocampus but not the prefrontal cortex.
.
Conclusion:
This study revealed the detrimental effects of CIP treatment on locomotor activity and motivation/learning ability during osteoarthritic condition, which might be due to, at least partially, deficient hippocampal BDNF expression and ensuing impairments in neural and synaptic plasticity.

Background and purpose To examine the ways of epileptogenesis closely linked to the system epilepsies' concept. Methods We follow the ways of epileptic transformation in the declarative memory-system, in the sleep/arousal twin-systems, in the perisylvian neuronal network and in postinjury epilepsy, which we consider a general model of the epileptic transformation. Results In the presented systems, epileptogenesis shares a similar mechanism in the form of augmentation and derailment of plasticity and sleep-related synaptic homeo-stasis. This highlights the central role of NREM sleep in those epilepsies. Conclusion We try to characterize the concept of system epilepsies and suggest a shared mechanism of epileptogenesis.

Background and purpose The aim of our research was to create a scoring system that predicts prognosis and recommends therapeutic options for patients with metastatic spine tumor. Increasing oncological treatment opportunities and prolonged survival have led to a growing need to address clinical symptoms caused by meta-stases of the primary tumor. Spinal metastases can cause a significant reduction in quality of life due to the caused neurological deficits. A scoring system that predicts prognosis with sufficient accuracy could help us to achieve personalised treatment options. Methods Methods - We performed a retrospective clinical research of data from patients over 18 years of age who underwent surgery due to symptomatic spinal metastasis at the National Institute of Mental Disorders, Neurology and Neurosurgery between 2008 and 2018. Data from 454 patients were analysed. Survival analysis (Kaplan-Meier, log-rank, Cox model) was performed, network science-based correlation analysis was used to select the proper prognostic factors of our scoring system, such that its C value (predictive ability index) was maximized. Results Multivariate Cox analysis resulted in the identification of 5 independent prognostic factors (primary tumour type, age, ambulatory status, internal organ metastases, serum protein level). Our system predicted with an average accuracy of 70.6% over the 10-year study period. Conclusion Our large case series of surgical dataset of patients with symptomatic spinal metastasis was used to create a risk calculator system that can help in the choice of therapy. Our risk calculator is also available online at https://emk.semmelweis.hu/gerincmet.

Aims - Overview of the new data about the strong link of sleep and epilepsy and conjoining cognitive impairment. Methods - Search for relevant references and summary of our own research activity on the topic. Results - Strong interrealtionship exists between epilepsy and plastic brain functions (memory processing and synaptic homeostasis) and the working modes of NREM sleep. In the most frequent childhood and adult epilepsy networks responsible for plastic functions can be derailed to an epileptic level of excitability, and suffer a transitory or permanent epileptic transformation. Exampling on the three big epilepsies: absence epilepsy; medial temporal lobe epilepsy; and childhood idiopathic focal age dependent epilepsy spectrum we demonstrate the most important features of this epileptic transformation. The association of cognitive impairment to certain sleep dependent epilepsies gains explanation by the epilepsy caused interference with slow wave decline (ICFE) and memory consolidation (MTLE) during NREM sleep. This paper serves also to introduce the concept of sleep dependent system epilepsies. Conclusions - We provide evidences about shared mechanisms among sleep related epilepsies being the derailment of sleep plastic funcions toward exaggerated excitability determined by the inherent possibilities of the signal transduction properties.

Introduction - Complex regional pain syndrome is a di-stressing neuropathic pain condition without known etiology and evidence based treatment. Case presentation - Here a posttraumatic severe case of complex regional pain syndrome is presented, successfully treated by amitriptyline monotherapy. Amitriptyline is one of the most effective evidence based treatments of peri-pheral diabetic neuropathic pain and other neuropathic pain syndromes. Discussion - Amitriptyline seems to be effective to decrease pain, autonomic and motor symptoms in chronic regional pain syndrome. Conclusion - Controlled trials may be warranted to test the effectiveness of amitriptyline in complex regional pain syndrome.
