The resurgence of tuberculosis in the Republic of Ireland: Perceptions and reality

Tuberculosis remained a very significant cause of death in Ireland until the mid-20th century and still occupies a prominent position in the folk memory. As I show with reference to recent Irish media coverage, the global resurgence of tuberculosis is therefore viewed with concern in Ireland. Using data collated by the Health Protection Surveillance Centre between 1998 and 2005 however, I show that the recent increase in tuberculosis incidence in Ireland is less than is popularly perceived. This increase is largely associated with economic immigrants attracted to Ireland by the ‘Celtic Tiger’ economic boom, but there is little evidence to suggest that this has had a negative impact on the Irish-born population. Drug resistance is still a small but growing problem. Whilst vigilance is required, it is argued that the recent increase does not at present indicate a likely return to the situation in the mid-20th century.     

Qualité des supports de communication de crise lors de la pandémie de la COVID-19 au Grand Maghreb

ObjectiveTo objectively assess the quality of “crisis communication” media, during the COVID-19 pandemic, in the three Greater Maghreb countries (Tunisia, Algeria, Morocco).MethodsA compliance audit for press releases and epidemiological bulletins was analyzed against a quality benchmark, which had been specifically designed by the authors. This framework, made up of five dimensions and 50 items, graded (0/1), was applied by two researchers in preventive medicine. Multiplying the scores by a coefficient of two resulted in a partial score of 20 points for each dimension and a total score of 100 points for the checklist taken as a whole. The quality of the communication media was considered to be good when exceeding the thresholds of 15/20 for the different dimensions and 75/100 for the entire grid.ResultsA total of 141 information media were included in this audit (Tunisia: 60; Algeria: 60; Morocco: 21). The overall median quality score for these media was only 56/100 (IIQ: [46–58]), without major variability between countries. The most appreciated dimension was “maintaining the confidence of the population”, with an overall median score of 14/20 (12/20 for epidemiological bulletins and 16/20 for press releases). The most poorly rated dimension was “strengthening community participation”, with a median score of only 4/20 (6/20 for epidemiological bulletins and 4/20 for press releases).ConclusionThe quality of the Maghreb crisis communication media during COVID-19 was insufficient in most of its dimensions and items, particularly from a psychosocial standpoint. Reinforcement of the capacities of communication officers to develop information material and supports during health crises is indispensable and should be considered as an urgent matter.

目的 分析慢性中耳炎及其并发症的高分辨率CT表现。方法 回顾性分析50例(60耳)慢性中耳炎患者的高分辨率CT表现,其中两例行MRI增强检查,并与手术所见及病理诊断对照。结果 鼓室腔内见软组织影52耳,听小骨受累51耳,鼓室、乳突内硬化斑形成14耳,面神经鼓室段受累5耳,迷路瘘1耳,骨化性迷路炎2耳。结论 高分辨率CT对诊断慢性中耳炎及其并发症以及指导临床治疗具有重要价值。     

慢性中耳炎鼓室成形术的围手术期治疗

目的 结合实践经验总结慢性中耳炎鼓室成形术的围手术期治疗体会.方法 回顾性分析2002年6月～2005年6月68例（72耳）慢性中耳炎患者的术前情况,根据纯音听阈、鼓膜穿孔类型、术前是否干耳、影像检查、耳源性并发症等决定手术方式,并对手术前后全身与局部系统的药物治疗及连续的手术后局部处理详细予以说明.结果 经过手术前期治疗、手术期治疗及手术后随诊处理,使医患双方均对该病围手术期的治疗形成正确的认识和理解.结论 ①对中耳炎患者的脓液进行细菌培养及药敏试验,并作为临床治疗上的参考,根据患者的具体情况,针对性选择用药;②手术前、后全身与局部系统性药物治疗及连续的手术后局部处理成为综合治疗慢性中耳炎不可缺少的三个方面.
