Barbiturate abuse.

The barbiturates are the drugs most commonly abused, and in his paper Dr d''Orban gives the general reader a clear, sober account of the drugs so abused, the pattern of abuse and the prevalence of the abuse of barbiturates. Sadly, some addicts add barbiturates to their abuse of other drugs upon which they depend. Dr d''Orban concludes his survey by telling how those addicted to barbiturates obtain the drugs and the hazards to which they expose themselves.     

Paralysis caused by "nagging"

A woman in her 20s presented to the emergency department, malnourished and dehydrated, and with acute paralysis of the lower limbs. Over the previous 10 days, she had inhaled nitrous oxide from "whipped-cream bulbs" (10-20 per day) for pain caused by a sprained ankle. She had a history of intravenous drug use and was on a methadone program. The nitrous oxide misuse combined with the malnutrition, with low vitamin B(12) levels, apparently resulted in subacute combined degeneration of the spinal cord--a rare complication of nitrous oxide misuse.     

2007-2017年烧伤后瘢痕研究的文献计量学分析

目的 了解烧伤后瘢痕的研究状况和发展趋势，为后续相关研究提供参考依据。方法 在Web of Science核心合集数据库检索烧伤后瘢痕的相关文献，应用文献计量学方法对文献的出版年份、国家或地区、机构、作者、文献研究方向、文献被引频次、文献来源出版物及其影响因子等方面进行分析。结果 2007-2017年Web of Science核心合集数据库共收录烧伤后瘢痕相关文献2 247篇，每年的文献量缓慢增长，发文量居第1位的国家或地区是美国（739篇，32.9%）、其次是中国大陆（195篇，8.7%），发文量最多的机构是澳大利亚昆士兰大学（57篇），发文量居第1位的作者是荷兰阿姆斯特丹自由大学的Middelkoop E（50篇）。烧伤后瘢痕研究方向主要为外科学和皮肤病学，文献主要来源于Burns和J Burn Care Res；发文量前10位的期刊2017年平均影响因子为2.068 9，其发文量占文献总量的39.2%（881/2 247）。结论 2007-2017年烧伤后瘢痕相关文献逐年缓慢增加，多发表在影响因子较低的期刊上。美国、荷兰、澳大利亚关于烧伤后瘢痕开展的研究较多，在推动学术交流和科学发展方面起到了重要作用。中国大陆的发文量显著增加，但在文献质量方面与西方发达国家还存在一定差距。     

Intracerebral haematoma caused by use of a "golf improver set"

Two cases of intracerebral haematoma caused by high-velocity impact from a golf ball--which was part of a "golf improver set", are described. Caution is advised in the use of such kits.
