银杏叶提取物注射液联合醋酸泼尼松治疗突发性耳聋的疗效观察

目的:探析银杏叶提取物注射液联合醋酸泼尼松治疗突发性耳聋的疗效。方法:选取2017年6月-2019年3月期间我院耳鼻喉科收治的96例突发性耳聋患者,按随机数表法为研究组(48例)和对照组(48例)。给予对照组醋酸泼尼松治疗,而研究组在对照组基础上增加银杏叶提取物注射液治疗,比较两组治疗效果、中医证候积分、血液流变学指标[血细胞比容(Hematocrit,HCT)、血浆黏度(Plasma Viscosity,PV)、红细胞聚集指数(Erythrocyte Aggregation Index,EAI)]以及不良反应。结果:研究组治疗总有效率较对照组更高,差异有统计学意义(P<0.05);治疗后,研究组中医证候积分、HCT、PV及EAI水平均明显低于治疗前和对照组,差异有统计学意义(P<0.05);两组均未出现不良反应。结论:银杏叶提取物注射液联合醋酸泼尼松治疗突发性耳聋安全、高效,可显著改善患者血液流变学,临床推广与应用价值较高。

儿童埋藏式心律转复除颤器的应用进展

埋藏式心律转复除颤器(ICD)在心源性猝死中有不可替代的作用,随着ICD技术的发展,儿童ICD植入也日趋增多,但由于儿童的特殊性,儿童ICD在应用指征、器械及植入方式的选择等方面仍面临着巨大挑战。现就儿童ICD临床应用的相关问题,包括常见病种、适应证及ICD系统的临床应用进行综述。     

Chronic exposure to ethanol in male mice may be associated with hearing loss in offspring

Although paternal ethanol (EtOH) abuse has been shown to affect the growth and behavior of offspring, the exact molecular and mechanistic basis remains largely unclear. Methylation alterations in imprinted genes may be related to well-documented teratogenic effects of ethanol. Here we show that chronic paternal ethanol exposure increases the susceptibility to abnormal behavior in offspring through male game epigenetic alteration. In our study, different doses of ethanol (0, 1.1, 3.3 g kg⁻¹) were administered intra-gastrically to male mice and decreased sperm motility was found in the highest ethanol-exposed group compared with the controls. Data also showed a dose-dependent increase in deaf mice of the paternally ethanol-exposed groups. The methylation of H19, Peg3, Ndn and Snrpn was assessed in paternal spermatozoa and in the cerebral cortices of deaf mice. EtOH affected methylation of Peg3 (CpG 3, 7 and 9) in paternal spermatozoa and in the cerebral cortices of deaf mice, but the level of mRNA expression did not change, suggesting that other gene regulation may be involved in these processes. Overall, chronic paternal ethanol exposure could alter the methylation of imprinted genes in sire spermatozoa that could also be passed on to offspring, giving rise to developmental disorders. Our results provide possible epigenetic evidence for a paternal ethanol exposure contribution to Fetal Alcohol Syndrome (FAS).     

Cerebellar artery infarction with sudden hearing loss and vertigo as initial symptoms: A case report

BACKGROUNDSudden hearing loss (SHL) is associated with serious systematic conditions such as neoplasms, vascular events, autoimmune diseases, infections, and iatrogenic injury. Some authors report that SHL can be an early warning sign of impending vertebrobasilar ischemic stroke. It is important to distinguish stroke from benign disease. CASE SUMMARYA 48-year-old male patient presented with SHL and vertigo as first symptoms. Diffusion-weighted imaging revealed high signal intensity in the left posterior inferior cerebellar artery territory of the cerebellar hemisphere and high signal intensity in the right pons and bridge cerebellar arm, confirming that the patient had cerebral infarction. Treatment with antiplatelet drugs, steroid anti-inflammatory drugs, and neurotrophic nerve therapy promoted blood circulation and removed blood stasis, and the symptoms of the patient were significantly improved. CONCLUSIONSHL and vertigo could be the initial symptoms of vertebrobasilar ischemic stroke.     

Registro Español de Desfibrilador Automático Implantable. XV Informe Oficial de la Sección de Electrofisiología y Arritmias de la Sociedad Española de Cardiología (2018)

Introduction and objectivesThis article presents the data corresponding to automated implantable cardioverter-defibrillator (ICD) implants in Spain reported to the Spanish Registry in 2018.MethodsThe data in this registry include both primary implants and generator replacements and were gathered from a data collection sheet voluntarily completed by implantation centers.ResultsIn 2018, 6421 implant sheets were received compared with 7077 reported by Eucomed (European Confederation of Medical Suppliers Associations). This represents data on 90.7% of the devices implanted in Spain. Compliance ranged between 99.6% for the field “name of the implanting hospital” and 12.4% for “population of residence”. A total of 173 hospitals reported their data to the registry, representing a slight decrease compared with hospitals participating in 2017 (n = 181).ConclusionsAfter the reduction in ICD implants in 2017, the number of implants increased in 2018, with the highest number of ICDs implanted in Spain. The total number of implants remains much lower than the European Union average, with substantial differences between autonomous communities.
