Abstract

Vertebral fracture is a common trauma can occur at any age group. Unstable fractures are treated surgically to restore the basic spinal functionality. In most cases, stable fractures are treated conservatively or by minimally invasive techniques. Pain is the most common symptom and can be a limiting factor for an early return to ones daily activities. Among the minimally invasive procedures for pain management are analgesis blockades, oxygenozone therapy, radiofrequency ablation or augmentation. This paper presents the current view of evidence-based medicine (EBM) on individual methods of pain treatment of which basic principles and aspects are discussed. Furthermore, the practical experiences of the author's workplace are presented. Over the past 8 years, more than 8,800 back pain treatments under CT guidance and 253 augmentation procedures have been performed at the authors' workplace. No clinically significant complication was observed. [ABSTRACT FROM AUTHOR]

Abstract

Percutaneous vertebroplasty is a minimally invasive procedure, in which fractured or otherwise affected vertebra is filled with polymethylmethacrylate (PMMA) cement. The main indications include osteoporotic vertebral fracture, spinal hemangioma, multiple myeloma and selected groups of patients with metastatic spinal injuries. The procedure leads to the stabilization of the affected vertebrae and then to analgesic effect. Our work presents a current view of vertebroplasty in these basic indication groups in light of current knowledge of evidence-based medicine (EBM). We are discussing and comparing the results of the studies concerning the treatment of osteoporotic fractures and other main indications for percutaneous vertebroplasty. [ABSTRACT FROM AUTHOR]

Abstract

Persistent primitive trigeminal artery belongs to the group of rare developmental intracranial vascular anomalies. This structure can be encountered at computed tomography (CT) and magnetic resonance imaging (MRI) or at angiographic studies of brain vessels. We report the case of an 18-year old woman in whom this artery was detected at MRI of the brain. Persistent primitive trigeminal artery is usually asymptomatic. However, it can cause neurologic symptoms, such as tic douloureux, according to literature. There is also reported concomitant occurrence of persistent trigeminal artery together with other vascular anomalies. Persistent trigeminal artery has a vital importance in surgery planning near the region of sella. It could be also considered significant in the case of stroke. [ABSTRACT FROM AUTHOR]

Abstract

Low back pain belongs to the most common health problems in general population, with increasing prevalence in recent decades. The involvement of the minimally invasive procedures increases in therapeutic approach to the patients suffering from low back pain. Periradicular therapy belongs to the most used method of this kind worldwide. Two novel minimally invasive methods: pulsed radiofrequency modulation and oxygen-ozone therapy are performed at CT department of Radiology Clinic of the University Hospital Hradec Králové for several years. CT helps to achieve higher level of efficacy and to lower the risk of procedural complications. Analgesic effect of these methods lasts approximately weeks to months, in our experience and also according to the literature. There is a possibility to repeat the procedures in time. The most common indication for these procedures is a low back pain with radicular symptomatology, or low back pain caused by facet joint syndrome. These methods can reduce the amount of used analgetics. [ABSTRACT FROM AUTHOR]

Abstract

Background: Neuromyelitis optica (NMO) and multiple sclerosis (MS) often manifest similar symptoms. However, the distinction between the two diseases is particularly important for different therapies. The aim of this study is to determine whether these diseases can be distinguished based on cerebral iron deposits in the deep grey matter and whether there is a correlation between iron deposits, local deep grey matter atrophy and clinical severity of the disease. Methods: 40 patients with relapsing-remitting MS (RRMS), 20 patients with NMO and 20 healthy subjects were examined at the MRI department of the 1st Faculty of Medicine of Charles University in Prague from December 2013 to March 2015. All patients with RRMS fulfilled the revised McDonald criteria, the diagnosis of NMO was based on Wingerchuk criteria. All 20 patients with NMO had positive AQP4-IgG. Quantitative susceptibility mapping (QSM) and volumometry of individual deep gray matter structures were performed. All patients with NMO and MS underwent simultaneous examination by a specialist in demyelinating diseases. Neurological disability was assessed by the Kurtzke Disability Status Scale (EDSS). Results: Patients with NMO have higher magnetic susceptibility values in the substantia nigra compared to healthy controls. Patients with RRMS...

Abstract

Multimodality MR imaging of pathological changes in schizophrenia Aim: To prove structural changes of the neocortex and white matter of the brain indicating connectivity disorder in early phases of schizophrenia. Material and methods: A prospective monocentric study comparing a cohort of patients after the first episode of schizophrenia (on average 15.6 days after the initial hospitalization) with a control group of healthy persons. Probands were examined using a complex MRI protocol. Twenty-six patients and twenty-four healthy persons were examined in total. Three dimensional T1 and T2 data and DWI data were analyzed using TBSS FA, FBA a surface- based morphometry. Results: Large areas of dispersively decreased FA were found in patients compared to control group using TBSS. Several fixels of decreased FD metric were found using FBA in the anterior commissure of patients and one sporadic fixel of decreased FDC metric was found in frontal white matter of the brain. No statistically significant areas of cortical surface area and cortical thickness differences were found using SBM. Conclusions: Large areas of decreased microstructural integrity of the white matter of the brain were found. However, it was not possible to specify the nature of its corruption using FBA. Our findings indicate the crucial role of...

Abstract

Aim: To compare the therapeutic efficacy of the three minimally invasive methods (PRF, KOT, PRT) in patients with chronic (more than 3 months lasting) unilateral radicular syndrome L5 or S1. The hypothesis: PRF and KOT are more effective than PRT in the treatment of chronic radicular pain. Material and methods: Prospective, randomized, unilaterally blinded, monocentric study. All patients underwent one of the procedures, navigated by CT. Two questionnaires: PainDETECT and Oswestry disability questionnaire were used to measure of the outcome - before treatment, immediately after and at the of 3th, 6th and 12th month after. Evaluated parameters: quantity of pain (VAS), neuropathic component of pain (NB), disability (ODI), character of pain (CHB), analgesic consumption (an), physiotherapy (re). Results: Group of 178 patients (115 women, 63 men, median age 56, BMI 27,5). (PRF 57, KOT 69, PRT 52). VAS was immediately reduced after procedures, mainly in PRT group with statistic significance in comparison - KOT to PRT (p = 0,0152). By the end of 3rd and 6th month after, the VAS values in all methods were similar, still lower than before treatment. PRT showed the best analgesic effect on NB, with statistical significance between PRT and PRF after 3rd and 6th month (p = 0,0457 and 0,0108, respectively)....
