Clinical evaluation of a potassium nitrate dentifrice for the treatment of dentinal hypersensitivity

Abstract The effectiveness of a 5% potassium nitrate dentifrice as a daily home treatment for dentinal hypersensitivity was evaluated in a double-blind study in 36 Japanese subjects who complained of cold and/or tactile hypersensitivity. The subjects were divided into 2 groups, with 18 being given a 5% potassium nitrate dentifrice (treated group) and the other 18 a vehicle paste (control group). Both groups were instructed to brush their teeth 2 × a day. The hypersensitivity levels of the affected teeth were assessed by 2 stimuli, one tactile and the other cold air, and by the perception of pain. The results of all 3 assessment methods indicated that the potassium nitrate dentifrice significantly decreased the level of hypersensitivity at weeks 4, 8, and 12. In the treated group, a rapid decrease of positive scores for both the cold air stimulus and the subjective symptoms appeared from week 2. Although a significant decrease of the assessment score was also observed in the control group, the reduction rate of the score was much greater in the treated group by ail 3 assessment methods at weeks 4, 8, and 12. Complete relief of subjective symptoms throughout the 12 weeks’examination was noted in 67% of the subjects in the treated group, but in only 6% in the control group. These results suggest the usefulness of a 5% potassium nitrate dentifrice in Japanese patients with dentinal hypersensitivity.     

同济医科大学控烟活动及效果评价

我校自1993年开展控烟工作，1995年9月开始创办无吸烟大学校园，采取了卫生宣教和行政干预等综合措施，并进行了效果评价。高强度干预措施实施前期（1995年3月）和中期（1996年10月）相比，男医学生和男女学生平均吸烟率分别从16.3％和11．4％下降到9．6％和5．94％；男教工和男女教工平均吸烟率分别从28．6％和13．8％下降到13．9％和8．86％。     

效益评价中指标筛选及其假设检验

西文介绍了综合效益评价中指标的逐步筛选及其假设检验方法，用该法选出的指标具有独立性强、代表性好的优点。同是分析处理了全国３４家县级医院的投入指标，从中筛选出５个指标参与评价。     

天津市煎炸油卫生状况评价

通过连续８小时的煎炸实验和对市，郊２９个煎炸点的现场卫生学调查及采用羰基值（ＣＯＶ），极性组分（ＰＣ）对所采样品的分析表明，天津煎炸油的总体的卫生质量基本符合国家卫生标准，参考极性组分的ＡＤＩ值并依据本次调查结果，估计天津大部分居民的煎炸食品摄入量安全水平，但对于偏爱煎炸食品者其安全系数明显下降。     

海南省妇幼保健机构现状与创等达标的对策

根据《妇幼保健机构等级评审标准》（下称《标准》）要求，对全省２０个妇幼保健机构现状进行了调查。结果显示：我省妇幼卫生工作基础薄弱，离《标准》要求差距较大；各机构间的发展极不平衡；县（市）级机构整体水平偏低，业务用房、人员、设备、床位等建设滞后；服务项目单一，二级专业分科不完善等矛盾较为突出。据此提出，在创等达标工作中，要依靠各级政府，努力争取各方面的支持，抓住机遇，迎接挑战，重点抓好软件建设，加强在职培训，积极引进人才，拓宽服务范围，规范自我，依法服务。     

Current practice in the pre-operative assessment of patients for elective repair of abdominal aortic aneurysmA survey of UK hospitals

A postal survey of 100 hospitals throughout the United Kingdom and Ireland was conducted to assess current practice in the pre-operative assessment and use of pulmonary artery catheters in patients undergoing elective abdominal aortic aneurysm repair. Seventy-four completed questionnaires were received. The survey revealed that 53% of respondents hold designated pre-operative assessment clinics, attended by anaesthetists in 54% and cardiologists in 26%. However, only 4% of respondents have a written protocol for stratifying patients and assessing peri-operative risk. By far the commonest investigation of choice for further cardiological assessment is transthoracic echocardiography (67%). Other investigations of choice are multiple update gated acquisition (MUGA) scan (13%), dipyridamole thallium imaging (9%), exercise ECG (6%), stress echocardiography (1%) and stress MUGA (1%). Two units (3%) never undertook further investigation. Pulmonary artery flotation catheters are used as a routine by 9% of respondents, dependent upon left ventricular ejection fraction by 65%, dependent on other factors by 7% and not used at all by 19%. The survey reveals widespread variation in pre-operative assessment of patients undergoing elective repair of abdominal aortic aneurysm.
