Cerebral small vessel disease (CSVD) represents a cluster of various vascular disorders with different pathological backgrounds. The advanced vasculature net of cerebral vessels, including small arteries, capillaries, arterioles and venules, is usually affected. Processes of oxidation underlie the pathology of CSVD, promoting the degenerative status of the epithelial layer. There are several classifications of cerebral small vessel diseases; some of them include diseases such as Binswanger’s disease, leukoaraiosis, cerebral microbleeds (CMBs) and lacunar strokes. This paper presents the characteristics of CSVD and the impact of the current knowledge of this topic on the diagnosis and treatment of patients.
Mitochondrial DNA changes can contribute to both an increased and decreased likelihood of cancer. This process is complex and not fully understood. Polymorphisms and mutations, especially those of the missense type, can affect mitochondrial functions, particularly if the conservative domain of the protein is concerned. This study aimed to identify the possible relationships between brain gliomas and the occurrence of specific mitochondrial DNA polymorphisms and mutations in respiratory complexes III, IV and V. The investigated material included blood and tumour material collected from 30 Caucasian patients diagnosed with WHO grade II, III or IV glioma. The mitochondrial genetic variants were investigated across the mitochondrial genome using next-generation sequencing (MiSeq/FGx system—Illumina). The study investigated, in silico, the effects of missense mutations on the biochemical properties, structure and functioning of the encoded protein, as well as their potential harmfulness. The A14793G (MTCYB), A15758G, (MT-CYB), A15218G (MT-CYB), G7444A (MT-CO1) polymorphisms, and the T15663C (MT-CYB) and G8959A (ATP6) mutations were assessed in silico as harmful alterations that could be involved in oncogenesis. The G8959A (E145K) ATP6 missense mutation has not been described in the literature so far. In light of these results, further research into the role of mtDNA changes in brain tumours should be conducted.
Introduction: Microsurgical treatment of VBSA is complex and challenging due to the deep location of the vessels and the proximity of important structures. Therefore, minimally invasive endovascular techniques have been introduced to the treatment of VBSA. The aim of this study was to present long-term results and technical aspects of VBSA embolisation. In this manuscript, we describe our experience in the treatment of VBSA with long-term results. Furthermore, we discuss the advantages and disadvantages of this treatment modality, paying special attention to the technical aspects. We believe that this is an important contribution to this topic because the number of previous reports is limited. It adds to a population that can be compared to patients treated using different methods. Materials and methods:We analysed the medical records of patients with aneurysms of vertebral and basilar arteries referred for endovascular treatment between 2015 and 2020.Results: A total of 44 patients were selected for the study. From this group, 10 patients (22.7%) were admitted with SAH caused by ruptured VBSA. The median age of the patients was 58 years (31-80), with 27 (61.4%) females and 17 (38.6%) males. The majority of the VBSAs (35, 79.5%) were located on the basilar artery. Complete occlusion was achieved in 39 patients (88.6%). Procedural complications occurred in three cases (6.8%). In long-term follow-up, complete embolisation was achieved in 81.8% (36 of 44 patients). In 18.2% (eight patients), recurrence of VBSA was observed. Two patients were qualified for recoiling. Clinical follow-up was uneventful in 37 (84%) patients. Four patients (9%) reported mild headaches. Three (7%) patients required assistance for daily living.Conclusions: Endovascular embolisation of VBSA is feasible and provides an excellent rate of complete occlusion and a high rate of favourable long-term outcomes, which support using this technique as a first-line treatment. A relatively high rate of recurrence remains the major drawback, especially in cases of wide-neck VBSA.
Eagle syndrome is a rare condition where an abnormally elongated (over 3cm) calcified stylohyoid ligament irritates the adjacent soft tissues, causing a number of symptoms related to neck movements, such as local pain, odynophagia, dyphagia, otalgia and limited neck mobility. The symptoms depend from the structures involved: cranial nerves VII, IX, X and XII, as well as internal jugular vein and carotid artery. The conservative treatment of the condition includes: non-steroidal antiinflammatory, antyepileptic drugs, physiotherapy and neck exercises, steroids, and local anesthetic injections. The possible surgical approaches are internal (transoral) or external -transcervical and parapharyngeal. The case is presented of a female patient who suffered neck and shoulder pain from the combined occurrence of left-sided elongated styloid and cervical disc herniation. She was successfully treated with resection of the styloid via parapharyngeal approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
