The article presents a clinical case of multiple sclerosis (MS) in a 10-year-old female patient, the use of one of the advanced magnetic resonance imaging (MRI) techniques, namely proton magnetic resonance spectroscopy (1H-MRS), in the diagnosis of MS. MRI is an integral part of the diagnostic algorithm for patients with multiple sclerosis according to the McDonald criteria, which were last updated in 2017. In addition, MRI allows assessing the course of the disease, serving as a criterion for confirming the aggravation of the pathological process. Although the McDonald criteria are applied in adults, they are also used to diagnose MS in children, and MS in children has its own particularities. The McDonald criteria include traditional (conventional) MRI sequences: T2-weighted images, T1-weighted images, post-contrast T1-weighted images. With the rapid development of MRI, cutting-edge (advanced) MRI techniques have emerged that allow for a better understanding of changes in the brain matter in MS: brain volumetry, magnetization transfer imaging, cortical imaging, diffusion tensor imaging, 1H-MRS, susceptibility-weighted imaging. In particular, 1H-MRS allows us to assess the degree of white matter integrity by detecting increased resonance of myelin breakdown metabolites. The studies have shown that changes in MS have their own specificity, but there is no consensus on this issue. Currently, there are no agreed guidelines that would include advanced MRI techniques, but we believe they will allow us to better understand the course of MS and to predict the development of the disease. This approach will improve the management of MS in both adults and children and quality of their life.
本文介绍了一名10岁的多发性硬化症(MS)女性患者的临床病例,在MS的诊断中使用先进的磁共振成像(MRI)技术之一,即质子磁共振波谱(1H-MRS),根据麦当劳标准,MRI是多发性硬化症患者诊断算法的一个组成部分,该标准于2017年更新。此外,MRI可以评估疾病的进程,作为确认病理过程恶化的标准。虽然麦克唐纳标准适用于成人,但也用于诊断儿童多发性硬化症,儿童多发性硬化症有其自身的特殊性。McDonald标准包括传统(常规)MRI序列:t2加权图像,t1加权图像,对比后t1加权图像。随着MRI的快速发展,尖端(先进)MRI技术已经出现,可以更好地了解MS中脑物质的变化:脑容量成像,磁化转移成像,皮质成像,弥散张量成像,1H-MRS,敏感性加权成像。特别是,1H-MRS允许我们通过检测髓磷脂分解代谢物增加的共振来评估白质完整性的程度。研究表明,MS的变化有其特异性,但在这一问题上尚无共识。目前,还没有包括先进核磁共振技术的一致指导方针,但我们相信,它们将使我们更好地了解多发性硬化症的病程,并预测疾病的发展。这种方法将改善成人和儿童多发性硬化症的管理和他们的生活质量。

Glioblastoma (GBM) is the most common and malignant adult brain tumor. Despite substantial study and surgical advancements, the prognosis remains poor, demanding ongoing research of the current trends and potential surgical therapy. This abstract summarizes GBM surgical developments and future directions. GBM is treated with maximal safe resection, adjuvant radiation, and chemotherapy. Tumor penetration into eloquent brain areas often complicates surgical excision. Functional brain mapping and intraoperative imaging have increase safe resection. Awake craniotomy and intraoperative fluorescence-guided surgery may help remove more tumor. GBM surgery now incorporates molecular and genetic data. Molecular profiling helps discover mutations and genetic changes for tailored treatment. Immunotherapies and targeted therapies have the potential to enhance treatment outcomes for patients diagnosed with GBM. Precision medicine, which involves tailoring cancer treatments to each patient’s unique characteristics, is expected to play a pivotal role in future research endeavors. Nanotechnology and drug delivery devices offer the opportunity to optimize the delivery of anti-tumor drugs, potentially improving their efficacy. Artificial intelligence and machine learning in preoperative planning and intraoperative decision-making should improve surgical results. Current trends in GBM surgery include maximizing safe resection using advanced mapping and imaging techniques, incorporating molecular information for personalized treatment, and investigating targeted therapies and immunotherapies. The future of GBM surgery lies in the integration of precision medicine, nanotechnology, and artificial intelligence. By adopting these innovations, the surgical management of GBM may experience significant improvements, leading to better patient outcomes and an increase in life quality.
胶质母细胞瘤(GBM)是成人最常见的恶性脑肿瘤。尽管有大量的研究和手术进展,但预后仍然很差,需要对当前趋势和潜在的手术治疗进行持续研究。本文总结了GBM手术的发展和未来发展方向。GBM的治疗采用最大安全切除、辅助放疗和化疗。肿瘤渗透到大脑的重要区域常常使手术切除复杂化。脑功能测绘和术中成像增加了安全切除。清醒开颅术和术中荧光引导手术可能有助于切除更多的肿瘤。GBM手术现在结合了分子和基因数据。分子谱分析有助于发现突变和基因变化,以便进行量身定制的治疗。免疫疗法和靶向治疗有可能提高诊断为GBM的患者的治疗效果。精准医学是指根据每位患者的独特特征定制癌症治疗方案,预计将在未来的研究努力中发挥关键作用。纳米技术和药物输送装置为优化抗肿瘤药物的输送提供了机会,有可能提高它们的疗效。人工智能和机器学习在术前规划和术中决策方面应提高手术效果。目前GBM手术的趋势包括使用先进的制图和成像技术最大限度地安全切除,结合分子信息进行个性化治疗,以及研究靶向治疗和免疫治疗。GBM手术的未来在于精准医学、纳米技术和人工智能的融合。通过采用这些创新,GBM的外科治疗可能会有显著的改善,从而导致更好的患者预后和生活质量的提高。

The data about vestibular disorders resulting from blast injury are contradictory. To disclose the problem of vestibular disorder as a consequence of a blast injury, we have done present investigation. One hundred and ten patients were examined: 65 Anti-Terrorist Operation (ATO) participants with mild traumatic brain injury (mTBI), 44 non-ATO plus one patient with acromegaly was examined using posturography. Questionnaire “Types of Dizziness” has been used according to the International Clinical Protocol on Vestibular Disorders (Dizziness). Complaints of dizziness (distortion of perception of space, movement and time) have been revealed in 70.77 % (46) ATO and 43.18 % (19) non-ATO patients: F-test = 0.51, T-test = 0.004, showing that this complaint is not specific to mTBI. Objective vertigo (sensation of the subjects moving around the patient) was detected in 26.15 % (17) ATO and 11.56 % (5) non-ATO patients: F-test = 0.027, T-test = 0.046. Thus, we have two different qualitative groups. So, these complaints are specific to the patients, who survived blast injury. Complaints of subjective vertigo are also typical for those with blast injury. Complaints of pseudovertigo are specific to the patients, who survived blast injury. Imbalance and drop attacks are not typical for ATO patients. Complaints of kinetosis are specific to the people with blast injury. Orthostatics (discomfort sensations that appear after sudden standing up) have been revealed in 76.92 % (50) ATO and 47.73 % (21) non-ATO patients, this complaint is not typical for mTBI. Vestibular system organizes space orientation tetrad: vestibular, somatosensory, visual and hearing information to percept, orient and interact with environment. Acro-, nycto- and ascendophobia have appeared to be of no importance. Agoraphobia (Greek αγωρα — market, supermarket syndrome, discomfort in open, public places or crowds) has been revealed in 33.85 % (22) ATO and 15.91 % (7) non-ATO patients; this complaint is not specific to mTBI. Claustrophobia (discomfort appearing in small, closed spaces) is detected in 20 % (13) ATO and 9.09 % (4) non-ATO patients: F-test = 0.024, T-test = 0.10. Thus, we have two different qualitative groups. It is also an interesting case, when we reveal qualitative difference without quantitative one. This is the argument to use F-test in our study. So, complaints of claustrophobia are specific to the patients, who survived blast injury. The same situation is with descendophobia (discomfort during walking down the hill or descending the staircase, patients note the necessity of visual control). The results are discussed from the point of view of a severe vestibular disorder due to the blast injury. The tallness correlated with drop attacks (R29.6 according to ICD-10, the nosology is missing in the Ukrainian translation), it is suggested that growth hormone might cause the fluctuation of vestibular function. Conclusions. 1. ATO participants have pronounced vestibular disorders. 2.
关于爆炸损伤引起的前庭功能障碍的数据是相互矛盾的。为了揭示爆炸伤后前庭功能障碍的问题,我们进行了本研究。对110例患者进行体位检查,其中65例为反恐行动(ATO)轻度创伤性脑损伤(mTBI), 44例为非ATO, 1例为肢端肥大症。调查问卷“头晕类型”是根据前庭疾病(头晕)国际临床协议使用的。70.77%(46例)ATO患者和43.18%(19例)非ATO患者有头晕主诉(空间、运动和时间感知扭曲):f检验= 0.51,t检验= 0.004,表明这种主诉并非mTBI特有。26.15%(17例)ATO患者和11.56%(5例)非ATO患者存在客观眩晕(受试者在患者周围移动的感觉):f检验= 0.027,t检验= 0.046。因此,我们有两个不同的定性组。所以这些抱怨都是针对那些在爆炸中幸存下来的病人。主观性眩晕的抱怨也是典型的那些爆炸伤害。假性眩晕的抱怨是特定的病人,谁幸存的爆炸伤害。失衡和跌落发作在ATO患者中并不常见。运动障碍的主诉是爆炸伤患者所特有的。76.92%(50例)ATO患者和47.73%(21例)非ATO患者出现矫形(突然站起来后出现不适感),这种主诉在mTBI中并不常见。前庭系统组织空间定向四分体:前庭、体感、视觉和听觉信息来感知、定位和与环境相互作用。横向、纵向和上升恐惧症似乎并不重要。33.85%(22例)ATO患者和15.91%(7例)非ATO患者有广场恐惧症(希腊αγωρα -市场、超市综合征,在露天、公共场所或人群中不适);此投诉并非针对mTBI。幽闭恐惧症(出现在狭小封闭空间的不适)在20% (13)ATO患者和9.09%(4)非ATO患者中存在:f检验= 0.024,t检验= 0.10。因此,我们有两个不同的定性组。这也是一个有趣的例子,我们揭示了质的差异而没有量的差异。这就是在我们的研究中使用f检验的理由。所以,幽闭恐惧症的症状只存在于那些在爆炸中幸存下来的病人身上。下山恐惧症也是同样的情况(下山或下楼梯时感到不适,患者注意到视觉控制的必要性)。本文从爆炸伤引起的严重前庭功能障碍的角度对结果进行了讨论。身高与跌落发作相关(根据ICD-10 R29.6,乌克兰翻译中缺少分类学),提示生长激素可能引起前庭功能波动。结论:1。ATO参与者有明显的前庭功能障碍。2. mTBI患者(ATO参与者)经历了严重的压力。3.前庭功能障碍的迹象,如主客观眩晕、运动障碍的主诉,在数量上和质量上都存在差异,因此,对ATO参与者来说是特定的。4. 假性眩晕症、幽闭恐惧症、下山恐惧症仅在质量上有所不同。5. 头晕、意识丧失、站立障碍、广场恐怖症仅在数量上不同。6. mTBI患者的身高在数量和质量上都与跌落发作的主诉相关。7. 在统计研究中,使用费雪矩阵检验是很重要的。

Background. Oxidative stress and immune cell (T-lymphocytes, macrophages) products are important for the development of morpho-functional disorders of the nervous system in Parkinson’s disease. Connection of Parkinson’s disease with age and functioning of the major histocompatibility complex genes are also shown. The purpose was to assess changes in the brain of T-lymphocytes, macrophages, malondialdehyde (MDA) contents, the activity of antioxidant enzymes, the structure of brain and spinal cord neurons, as well as behavior in adult and aging mice with different H-2 haplotypes and toxic model of parkinsonism. Materials and methods. Adult and aging female mice of FVB/N (genotype H-2q) and 129/Sv (genotype H-2b) strains were once injected with the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) at the dose of 30 mg/kg. Contents of CD3+, CD3–CD11b+, CD3+CD11b+ cells, MDA and the activity of antioxidant enzymes in the brain were evaluated. The structure of neurons of the substantia nigra, lumbar spine, behavior in the open field test, as well as in rigidity and rotarod performance tests were studied. Results. In adult mice of both strains, motor and non-motor (spatial-exploratory, emotional) activity is impaired under the influence of MPTP. At the same time, linear differences in behavior changes were revealed in their directions and expressiveness. In aging FVB/N experimental mice, motor behavior disorders prevailed and were combined with non-motor changes in 129/Sv mice. Violations in the structure of substantia nigra neurons after MPTP administration were more severe in FVB/N mice while those in the lumbar spinal cord neurons were more pronounced in the 129/Sv mice. In aging experimental mice of both strains, the percentage of damaged neurons in the brain and spinal cord was significantly lower than in adult animals. After MPTP administration to adult mice, the direction of changes in the brain T-lymphocytes and macrophages (increase or decrease) depended on their strains. In aging experimental mice, the linear heterogeneity of changes was preserved for the T-lymphocyte content, while the macrophage level was increased regardless of the animal strains. Under MPTP influence, the MDA content increased in the brain of mice of all experimental groups. The direction of changes in superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase activities (decrease or increase) depended on the strains of animals and their age. Conclusions. MPTP-induced changes (directions, expressiveness) in T-lymphocyte, macrophage contents, antioxidant enzymes activity, the structure of neurons of the substantia nigra and lumbar spine, as well as behavioral reactions largely depended on the adult mice H-2 haplotype. There were age-related effects of the neurotoxin on changes in the studied indicators in mice of different strains. At the same time, dependence of changes in most above indicators on the H-2 haplotype preserved.
背景。氧化应激和免疫细胞(t淋巴细胞,巨噬细胞)产物对帕金森病神经系统形态功能障碍的发展很重要。帕金森病与年龄和主要组织相容性复合体基因功能的关系也被显示出来。目的是研究不同H-2单倍型和帕金森中毒模型的成年和老年小鼠脑内t淋巴细胞、巨噬细胞、丙二醛(MDA)含量、抗氧化酶活性、脑和脊髓神经元结构以及行为的变化。材料和方法。将FVB/N(基因型H-2q)和129/Sv(基因型H-2b)的成年和老年雌性小鼠一次性注射30 mg/kg的神经毒素1-甲基-4-苯基-1,2,3,6-四氢吡啶(MPTP)。测定大鼠脑组织CD3+、CD3 - CD11b+、CD3+CD11b+细胞含量、MDA含量及抗氧化酶活性。研究了大鼠腰椎黑质神经元的结构、裸场试验行为、刚性和旋转性能试验。结果。在这两个品系的成年小鼠中,运动和非运动(空间探索,情绪)活动在MPTP的影响下受损。与此同时,行为变化的方向和表达方式也呈现出线性差异。在老年FVB/N实验小鼠中,129/Sv小鼠运动行为障碍普遍存在,并伴有非运动改变。MPTP对FVB/N小鼠黑质神经元结构的破坏更为严重,而对129/Sv小鼠腰椎神经元的破坏更为明显。在这两个品系的衰老实验小鼠中,大脑和脊髓中受损神经元的百分比明显低于成年动物。MPTP给药后,成年小鼠脑t淋巴细胞和巨噬细胞的变化方向(增加或减少)取决于其品系。在衰老实验小鼠中,t淋巴细胞含量的变化保持线性异质性,而巨噬细胞水平升高与动物品系无关。MPTP作用下,各实验组小鼠脑内MDA含量均升高。超氧化物歧化酶、过氧化氢酶、谷胱甘肽过氧化物酶和谷胱甘肽还原酶活性的变化方向(降低或增加)与动物品系和年龄有关。结论。mptp诱导的t淋巴细胞、巨噬细胞含量、抗氧化酶活性、黑质和腰椎神经元结构以及行为反应的改变(方向、表达)在很大程度上取决于成年小鼠H-2单倍型。在不同品系的小鼠中,神经毒素对所研究指标的变化有年龄相关的影响。同时,上述大部分指标的变化对H-2单倍型的依赖性保持不变。

The data about vestibular disorders resulting from blast injury are contradictory. To disclose the problem of vestibular disorder as the consequence of blast injury, we have done present investigation. One hundred and nine patients were examined: 65 Anti-Terroristic Operation (ATO) participants, who survived mild and moderate blast injury without cranial trauma, and 44 non-ATO patients (rhinitis, pharyngitis, otitis). Questionnaire “Types of dizziness” has been used according to the International Clinical Protocol on Vestibular Disorders (Dizziness). Complaints of dizziness (distortion of perception of space, movement and time) have been revealed in 70.77 % (46) ATO and 43.18 % (19) non-ATO patients: F-test = 0.51, T-test = 0.004, thus, showing that this complaint is not specific for mild traumatic brain injury (mTBI). Objective vertigo (sensation of subjects moving around the patient) met in 26.15 % (17) ATO and 11.56 % (5) non-ATO patients: F-test = 0.027, T-test = 0.046. So, we have two different qualitative groups. Тhese complaints are specific for the patients, who survived blast injury. Complaints of vertigo are also typical for the patients, who survived blast injury. Complaints of giddiness are specific for the patients, who survived blast injury. Imbalance and drop attacks are not typical for ATO patients. Complaints of kinetosis are specific for the patients, who survived blast injury. Orthostatics (discomfort sensations that appear after sudden standing up) has been revealed in 76.92 % (50) ATO and 47.73 % (21) non-ATO patients, this complaint is not specific for mTBI. Vestibular system organizes space orientation tetrad: vestibular, somatosensory, visual and hearing information to percept, orient and interact with environment. Acro-, nycto- and ascendophobia have appeared to be of no importance. Agoraphobia (Greek αγωρα — market, supermarket syndrome, discomfort in open, public places or crowds) has been detected in 33.85 % (22) ATO and 15.91 % (7) non-ATO patients. This complaint is not specific for mTBI. Claustrophobia (discomfort appearing in small, closed spaces) is met in 20.00 % (13) ATO and 9.09 % (4) non-ATO patients: F-test = 0.024, T-test = 0.10. Thus, we have two different qualitative groups. This is also interesting case, when we reveal qualitative difference without quantitative one. This is the argument to use F-test in our study. So, complaints of claustrophobia are specific for the patients, who survived blast injury. The same situation is with descendophobia (discomfort during walking down the hill or descending the staircase, patients note the necessity of visual control. It has been shown that among other signs, there is a positive correlation with age, imbalance, ascendophobia and dyspnea). The results are discussed from the point of view of the severe vestibular impairment due to the blast injury. Conclusions. 1.

关于爆炸损伤引起的前庭功能障碍的数据是相互矛盾的。为了揭示爆炸伤后前庭功能障碍的问题,我们进行了本研究。109名患者接受了检查:65名反恐行动(ATO)参与者,他们在轻度和中度爆炸伤中幸存,没有颅脑损伤,44名非ATO患者(鼻炎,咽炎,中耳炎)。调查问卷“头晕类型”是根据前庭疾病(头晕)国际临床协议使用的。70.77%的ATO患者(46例)和43.18%的非ATO患者(19例)出现头晕主诉(空间、运动和时间感知扭曲):f检验= 0.51,t检验= 0.004,因此,这种主诉不是轻度创伤性脑损伤(mTBI)特有的。26.15%(17例)ATO患者和11.56%(5例)非ATO患者出现客观眩晕(被试在患者周围移动的感觉):f检验= 0.027,t检验= 0.046。所以,我们有两个不同的定性组。Тhese投诉是针对那些在爆炸中幸存下来的病人。对于那些在爆炸中幸存下来的病人来说,眩晕也很常见。眩晕是那些在爆炸中幸存下来的病人特有的症状。失衡和跌落发作在ATO患者中并不常见。运动障碍的主诉是爆炸伤幸存者特有的。76.92%(50例)ATO患者和47.73%(21例)非ATO患者出现矫形(突然站起来后出现不适感),这种主诉并非mTBI特有。前庭系统组织空间定向四分体:前庭、体感、视觉和听觉信息来感知、定位和与环境相互作用。横向、纵向和上升恐惧症似乎并不重要。广场恐怖症(希腊αγωρα -市场、超市综合征,露天、公共场所或人群不适)在33.85%(22例)ATO和15.91%(7例)非ATO患者中检测到。这个抱怨不是针对mTBI的。幽闭恐惧症(出现在狭小封闭空间的不适)在20.00% (13)ATO患者和9.09%(4)非ATO患者中存在:f检验= 0.024,t检验= 0.10。因此,我们有两个不同的定性组。这也是一个有趣的例子,当我们揭示质的差异而不揭示量的差异时。这就是在我们的研究中使用f检验的理由。所以,幽闭恐惧症的症状是针对那些在爆炸中幸存下来的病人的。下山恐惧症(下山或下楼梯时感到不适)也是同样的情况,患者注意到视觉控制的必要性。研究表明,在其他迹象中,与年龄、失衡、上升恐惧症和呼吸困难呈正相关。本文从爆炸致严重前庭损伤的角度对结果进行了讨论。结论:1。爆炸伤所致MBTI伴有严重的应激、主客观眩晕、眩晕和运动障碍,被认为是前庭损伤的症状。2. 在mBTI患者中,眩晕、直立和广场恐怖症在数量上显著增加,但可能不被认为是爆炸伤害后果的特异性。3.与耳鼻喉科患者相比,ATO患者的眩晕、幽闭恐怖症和下降恐惧症没有定量变化,但这是mBTI在爆炸伤后特有的。4. 在统计检验中使用矩阵费雪检验是很重要的。

Background. The development and availability of genetic research open both new possibilities in the diagnosis of epileptic encephalopathies and require the search for correlations between detected pathological mutation and the clinical and instrumental examination of a child. In particular, seizure disorders in children in whom SCN1A has been detected cover a spectrum that varies from simple febrile seizures and mild generalized epilepsy with febrile seizures plus, which was first described in 2003, to severe myoclonic epilepsy in infancy (more commonly known as Dravet syndrome) or severe intractable childhood epilepsy with generalized tonic-clonic seizures. Materials and methods. In our study, we examined 4 children (2 boys and 2 girls) with clinical and instrumental signs of epileptic encephalopathy with resistant seizures who were treated in the psychoneurology department for children with perinatal pathology and orphan diseases of the SI “Lukyanova Institute of Pediatrics, Obstetrics and Gynecology named of the National Academy of Medical Sciences of Ukraine”. The average age of patients was 2.20 ± 1.55 years. In addition to the laboratory and instrumental examination, all children underwent a medical genetic analysis (whole exome sequencing or next-generation sequencing) and the mutation of the SCN1A gene was detected. Subsequently, the relationship between the obtained laboratory instrumental and clinical anamnestic data was analyzed using statistical research methods. Results. It should be noted that the onset of genetic disorders caused by SCN1A occurs at the age of 5.5–6 months. During the onset, focal clonic seizures predominate, mainly against the background of hyperthermia, which are later modified into generalized tonic-clonic, myoclonic ones, and even absences. In three of four cases, the epileptiform activity was focal, with a predominant localization in the fronto-central regions followed by generalization. In all children, taking into account the focal onset of attacks, therapy was started with the use of carbamazepine, which is contraindicated in children with this mutation. After analyzing our cases, we saw that the course of the disease and the resistance of attacks were more severe in girls. The study of this phenomenon requires observation of a larger number of children. Conclusions. In children with genetically determined epileptic encephalopathy caused by the SCN1A mutation, the onset of the disease occurs in the first half of life and is usually manifested itself by focal seizures. In children with SCN1A mutation, frontal localization of epileptiform activity prevails. Considering this feature of the disease and based on our own long-term observation of children with epileptic encephalopathies of early age, we would like to warn against the use of carbamazepines in this age group. The course of SCN1A epileptic encephalopathy (Dravet syndrome) is difficult, given the resistance of attacks and regression in the development
背景。遗传研究的发展和可用性为癫痫性脑病的诊断开辟了新的可能性,并要求寻找检测到的病理突变与儿童的临床和仪器检查之间的相关性。尤其值得一提的是,SCN1A患儿的癫痫发作障碍涵盖了从单纯发热性癫痫发作和轻度全身性癫痫伴发热性癫痫发作(2003年首次报道)到婴儿期严重肌阵挛性癫痫(更常见的是Dravet综合征)或严重难治性儿童癫痫伴全身性强直-阵挛性癫痫发作的范围。材料和方法。在我们的研究中,我们检查了4名儿童(2男2女),他们有癫痫性脑病的临床和仪器症状,并伴有抵抗性癫痫发作,他们在“乌克兰国家医学科学院卢基扬诺娃儿科、妇产科研究所”的精神神经科治疗围产期病理和孤儿病儿童。患者平均年龄2.20±1.55岁。除了实验室和仪器检查外,所有儿童都进行了医学遗传分析(全外显子组测序或下一代测序),并检测了SCN1A基因的突变。随后,使用统计研究方法分析了获得的实验室仪器与临床记忆数据之间的关系。结果。值得注意的是,SCN1A引起的遗传性疾病发生在5.5-6个月大时。在发病期间,局灶性阵挛性发作为主,主要是在高热背景下发生的,后来会转变为全身性强直-阵挛、肌阵挛,甚至无发作。在四分之三的病例中,癫痫样活动是局灶性的,主要定位在额中央区域,其次是泛化。在所有儿童中,考虑到发作的局灶性,治疗开始时使用卡马西平,这是具有这种突变的儿童的禁忌症。在分析我们的病例后,我们发现女孩的病程和抵抗性更严重。对这一现象的研究需要观察更多的儿童。结论。在由SCN1A突变引起的遗传性癫痫性脑病患儿中,该疾病发生在生命的前半生,通常表现为局灶性癫痫发作。在SCN1A突变的儿童中,癫痫样活动的额叶定位普遍存在。考虑到该疾病的这一特点,并根据我们自己对早期癫痫性脑病患儿的长期观察,我们要警告在这个年龄组不要使用卡马西平。SCN1A癫痫性脑病(Dravet综合征)的治疗过程是困难的,考虑到儿童在发育过程中对发作的抵抗力和退行性,通常需要使用2-3种以上的抗癫痫药物,但正确选择组合可以实现长期缓解。

Background. The problem of effective prolonged epidural analgesia (PEA) in case of hypotonic labor, which allows minimal intervention in the process of labor activity while providing adequate analgesia, remains unresolved. A study was conducted to increase the effectiveness of PEA use during the first state of childbirth in women with hypotonic labor. The purpose: to increase the effectiveness of prolonged epidural analgesia in case of hypotonic labor during vaginal childbirth. Materials and methods. We performed analgesia to 60 women with a diagnosis of stage 1 hypotonic labor who were divided in 2 groups: the main one (n = 35) and the controls (n = 25). ASA status in both groups was I–II. In both groups, the epidural space was punctured at L1-L2. A test 4-ml dose of 2% lidocaine solution was administered and 5 minutes after, the epidural catheter was inserted. Then, in the main group, 1 ml of fentanyl solution and 6 ml of 0.9% NaCl were injected into the epidural space; in the control group, 6–8 ml of 0.125% bupivacaine solution. The effectiveness was evaluated according to the visual analogue scale, hemodynamic changes and the outcome of childbirth (conservative or operative). The condition of the fetus was assessed according to cardiotocography data. Statistical processing of the material was carried out using Excel. Results. The use of fentanyl in 69 % of cases allowed finishing the birth conservatively, the condition of the fetus and newborn was considered satisfactory. In the control group, 72 % of births resulted in cesarean section. Indications for surgery were hypotonic labor and fetal distress. Conclusions. The use of the narcotic analgesic fentanyl for prolonged epidural analgesia in hypotonic labor effectively relieves pain and increases the likelihood of conservative childbirth. It is safe for mother, fetus and newborn.
背景。在低张力分娩的情况下,有效的延长硬膜外镇痛(PEA)的问题仍然没有解决,它允许对分娩活动过程进行最小的干预,同时提供足够的镇痛。一项研究是为了提高低渗分娩妇女在分娩第一阶段使用PEA的有效性。目的:提高阴道分娩时低张力分娩时延长硬膜外镇痛的有效性。材料和方法。我们对60例诊断为1期低渗分娩的妇女进行了镇痛,将她们分为两组:主要组(n = 35)和对照组(n = 25)。两组ASA均为I-II级。两组均在L1-L2处穿刺硬膜外间隙。给予2%利多卡因溶液4 ml试验剂量,5分钟后插入硬膜外导管。主组在硬膜外腔内注射芬太尼溶液1 ml和0.9% NaCl 6 ml;对照组:0.125%布比卡因溶液6 - 8ml。根据视觉模拟评分、血流动力学变化和分娩结果(保守或手术)评估疗效。根据心脏造影资料评估胎儿状况。使用Excel对材料进行统计处理。结果。69%的病例使用芬太尼保守地完成了分娩,胎儿和新生儿的情况被认为是令人满意的。在对照组中,72%的分娩结果为剖宫产。手术指征为低张力分娩和胎儿窘迫。结论。麻醉镇痛药芬太尼用于低张力分娩时的长时间硬膜外镇痛,可有效减轻疼痛,增加保守分娩的可能性。对母亲、胎儿和新生儿是安全的。

Background. Limb damage dominates in the structure of combat trauma, making up to 75 % in modern wars and the number of wounded with peripheral nerve injuries of the limbs can be up to 25 %. The degree of disability of patients is 65–70 %, which makes the problem of restoring peripheral nerves extremely actual. The purpose of the study was to determine the effect of long-term invasive electrical stimulation on the functional restoration of the neuromuscular complex in experiment. Materials and methods. The study was performed on 29 white outbred rabbits (2500 ± 250 g, 5–6 months) according to all norms of bio­ethics. Animals were divided into the following experimental groups: group 1 (n = 8, controls) — epineural suture of the sciatic nerve and implantation of a non-working antenna of the electrical stimulation device; group 2 (n = 7): similar operation of epineural suture of the sciatic nerve with implantation of the electric stimulator antenna and stimulation on beginning at the 2nd day after the operation; group 3 (n = 7): a similar operation of the sciatic nerve epineural suture with implantation of an electric stimulator antenna and the start of stimulation after 2 weeks, when the initial signs of nerve regeneration were observed; group 4 (n = 7): autografting of the sciatic nerve and implantation of an electrical stimulator and the beginning of stimulation at a time point that will coincide with the signs of nerve regeneration. Results. Therefore, in group 2, where electrical stimulation was started the day after the operation, the indicators of functional recovery of the neuromuscular complex were better than in its absence, as well as under the conditions of starting the stimulation in the period when the initial signs of regeneration were observed. Therefore, it can be assumed that the invasive electrical stimulation of the peripheral nerve, started in the acute period after the injury, has a positive effect on the regeneration of the peripheral nerves, as well as on the results of the functional restoration of the neuromuscular complex. The positive effect of electrical stimulation on the functional state of muscles is indirectly evidenced by the larger amplitude of the compound muscle action potential (CMAP) in the group where the stimulation was started faster. A larger amplitude of the CMAP during the observation indicates a greater number of axons that reached the muscle during 8 weeks. Given that the growth cone of the regenerating nerve contains a certain number of axons that first grow to the effector organ, in this case the muscle, with a relatively unchanged action potential latency, it can be assumed that direct electrical stimulation of the peripheral nerve leads to an increase speed of axons sprouting, with their relatively unchanged number. The absence of a significant difference in the action potential latency in the groups where autografting and suture were performed under the same conditions of stimulation indicates a p
背景。肢体损伤在战斗创伤结构中占主导地位,在现代战争中占75%,肢体周围神经损伤的人数可达25%。患者的残疾程度为65 - 70%,这使得周围神经的恢复问题非常现实。本研究的目的是在实验中确定长期有创性电刺激对神经肌肉复合体功能恢复的影响。材料和方法。试验选用29只纯种白兔(2500±250 g, 5 ~ 6月龄),按生物伦理学各项规范进行。实验动物分为以下实验组:1组(n = 8,对照组)-坐骨神经神经外缝合和植入电刺激装置的非工作天线;第二组(n = 7):术后第2天开始行坐骨神经神经外缝合术,植入电刺激器天线,并进行刺激;第三组(n = 7):采用类似的坐骨神经外神经缝合术,植入电刺激器天线,2周后开始刺激,观察神经再生的初步迹象;第4组(n = 7):坐骨神经自体移植和植入电刺激器,并在与神经再生迹象一致的时间点开始刺激。结果。因此,在术后第1天开始电刺激的2组,神经肌肉复合体功能恢复指标优于不进行电刺激的组,以及在观察到再生初期迹象的时间段开始电刺激的组。因此,可以认为,在损伤后急性期开始的有创性周围神经电刺激,对周围神经的再生以及神经肌肉复合体功能恢复的结果都有积极作用。电刺激对肌肉功能状态的积极影响间接体现在刺激开始更快的组中复合肌肉动作电位(CMAP)的振幅更大。观察期间CMAP的振幅越大,表明在8周内到达肌肉的轴突数量越多。鉴于再生神经的生长锥中含有一定数量的轴突,轴突首先生长到效应器,即肌肉,其动作电位潜伏期相对不变,可以认为直接电刺激周围神经导致轴突发芽速度加快,轴突发芽数量相对不变。在相同的刺激条件下,自体移植和缝合组的动作电位潜伏期没有显著差异,这表明刺激对神经纤维的髓鞘形成有积极作用。良好的CMAP间接表明肌肉的功能状态令人满意,这在去神经支配的情况下可以保留其恢复的潜力并防止萎缩。结论。综上所述,根据电生理研究数据,我们可以间接得出如下结论:1)有创性电刺激对神经肌肉复合体再生的影响是积极的,损伤后早期进行电刺激效果更好;对周围神经进行侵入性电刺激是一种可以加速神经纤维生长、改善其髓鞘形成和防止失神经支配肌肉功能丧失的方法。

Limb damage dominates in the structure of combat trauma, making up to 75 % in modern wars and the number of wounded with peripheral nerve injuries of the limbs can be up to 25 %. The degree of disability of patients is 65–70 %, which makes the problem of restoring peripheral nerves extremely actual. The purpose of the study was to determine the effect of long-term invasive electrical stimulation on the functional restoration of the neuromuscular complex in experiment. Materials and methods. The study was performed on 29 white outbred rabbits (2500 ± 250 g, 5–6 months) according to all norms of bio­ethics. Animals were divided into the following experimental groups: group 1 (n = 8, controls) — epineural suture of the sciatic nerve and implantation of a non-working antenna of the electrical stimulation device; group 2 (n = 7): similar operation of epineural suture of the sciatic nerve with implantation of the electric stimulator antenna and stimulation on beginning at the 2nd day after the operation; group 3 (n = 7): a similar operation of the sciatic nerve epineural suture with implantation of an electric stimulator antenna and the start of stimulation after 2 weeks, when the initial signs of nerve regeneration were observed; group 4 (n = 7): autografting of the sciatic nerve and implantation of an electrical stimulator and the beginning of stimulation at a time point that will coincide with the signs of nerve regeneration. Results. Therefore, in group 2, where electrical stimulation was started the day after the operation, the indicators of functional recovery of the neuromuscular complex were better than in its absence, as well as under the conditions of starting the stimulation in the period when the initial signs of regeneration were observed. Therefore, it can be assumed that the invasive electrical stimulation of the peripheral nerve, started in the acute period after the injury, has a positive effect on the regeneration of the peripheral nerves, as well as on the results of the functional restoration of the neuromuscular complex. The positive effect of electrical stimulation on the functional state of muscles is indirectly evidenced by the larger amplitude of the compound muscle action potential (CMAP) in the group where the stimulation was started faster. A larger amplitude of the CMAP during the observation indicates a greater number of axons that reached the muscle during 8 weeks. Given that the growth cone of the regenerating nerve contains a certain number of axons that first grow to the effector organ, in this case the muscle, with a relatively unchanged action potential latency, it can be assumed that direct electrical stimulation of the peripheral nerve leads to an increase speed of axons sprouting, with their relatively unchanged number. The absence of a significant difference in the action potential latency in the groups where autografting and suture were performed under the same conditions of stimulation indicates a p","PeriodicalId":14476,"journal":{"name":"INTERNATIONAL NEUROLOGICAL JOURNAL","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78261907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article deals with the topical issue of today — ischemic strokes in young people. Currently, there are more than 150 identified causes of ischemic stroke, the most common of them are antiphospholipid syndrome, Fabry disease, genetic mutations, acquired and congenital thrombophilia, heart defects, a number of infectious agents, comorbid nosologies (migraine), and the use of narcotic agents. Special attention was paid to the monogenic disorders, which begin from an ischemic stroke or in which this type of stroke is one of the leading characteristics. The article shows in detail the characteristic features of each pathology, methods of diagnosis and ways of treatment, which is necessary in the work of a neuropathologist and doctors of other specialties.

Background. The growing number of patients with dementia in aging population of developed countries significantly increases the relevance of differential diagnosis of cognitive impairment and age-associated cognitive disorders. The purpose of the study was to determine the criteria for physiological changes in cognitive status and diffusion processes in brain’s white matter in healthy middle-aged and elderly people. Material and ­methods. Thirty-nine healthy middle-aged (45–59 years, n = 19) and elderly patients (60–75 years, n = 20) were examined. Neuropsychological testing was performed using the following scales: Montreal Cognitive Assessment, Mini-Mental State Examination, Frontal Assessment Battery, Semantic Verbal Fluency (SVF) and Phonemic Verbal Fluency (PVF). Molecular diffusion in brain’s white matter was investigated by diffusion tensor imaging (Ingenia 3.0T, Philips). Results. Moderate positive correlations were found between age and the Frontal Assessment Battery score (rs = –0.443), memory (rs = –0.444) and executive function (rs = –0.542). Cognitive functions in middle-aged and elderly patients didn’t differ in cognitive domains of naming (II), memory (III), language (VIII), delayed reproduction (X), orientation (XI), semantic and phonemic verbal fluency. At the same time, differences in attention (IV, VI, AIS: p = 0.038; 0.043; < 0.001), language (VII, LIS: p < 0.001), abstraction (IX: p = 0.008) and visuospatial function (VIS: p = 0.002) were significant. Physiolo-gical age-related changes of molecular diffusion in the white matter of the cerebral hemispheres are characterized by a decrease of 21.0–37.0 % (p = 0.02 — < 0.001) in anisotropic and an increase of 16.3–29.5 % (p < 0.001) in free diffusion of water molecules in the conductive tracts and beyond them.
背景。发达国家老年人口中痴呆症患者数量的增加显著增加了认知障碍和年龄相关认知障碍鉴别诊断的相关性。本研究旨在确定健康中老年人认知状态和脑白质扩散过程的生理变化标准。材料和方法。39例健康中年患者(45-59岁,n = 19)和老年患者(60-75岁,n = 20)。采用以下量表进行神经心理测试:蒙特利尔认知评估、迷你精神状态测试、额叶测试、语义语言流畅性(SVF)和音素语言流畅性(PVF)。采用扩散张量成像技术(Ingenia 3.0T, Philips)研究脑白质中的分子扩散。结果。年龄与正面评估电池评分(rs = -0.443)、记忆(rs = -0.444)和执行功能(rs = -0.542)呈正相关。同时,注意差异(IV, VI, AIS: p = 0.038;0.043;< 0.001),语言(VII, LIS: p < 0.001),抽象(IX: p = 0.008)和视觉空间功能(VIS: p = 0.002)显著。脑半球白质中分子扩散的生理相关变化表现为各向异性减少21.0% ~ 37.0% (p = 0.02 ~ < 0.001),而水分子在导电束及其外的自由扩散增加16.3% ~ 29.5% (p < 0.001)。
