Family system test (FAST): Are parents' and children's family constructs either different or similar,or both?

Perceptions of family cohesion and hierarchy structures were assessed by theFamily System Test (FAST), a clinically-derived figure placement technique. Parents (N=140) and their preadolescent offspring (N=70) completed typical and conflict representations in individual as well as group settings. Typical representations were characterized by balanced family structures (i.e. cohesive and moderately hierarchical) and those displaying conflict situations showed predominantly unbalanced patterns. FAST portrayals were related to respondent (mother vs. father vs. child). Fathers represented typical family relations as balanced more often than mothers. Regarding conflict representations, children were more likely than fathers to portray the family as unbalanced. However, analyses of representations of the same family (i.e. intra-family comparisons) indicated that all respondents differed in their perceptions and, that fathers' typical portrayals showed most often the same structure as those done by the family members as a group.

668颗后牙镍铬合金PFM边缘适合性的临床观察

目的：观察采用2种边缘形式的后牙烤瓷熔附金属全冠边缘适合性和对牙龈健康的影响.方法：对668颗后牙,分别采用2种边缘形式的后牙烤瓷熔附金属全冠（单冠或桥的基牙）在修复2年后进行复查,检测其边缘适合性及牙龈指数（GI）和牙周探诊深度（PD）,用统计学方法分析修复体边缘形式与牙龈病变间的关系.结果：采用羽状边缘360°金属脚边的PFM边缘适合性明显优于凹面肩台型边缘PFM,凹面肩台型边缘的PFM的牙龈病变发生率,明显高于羽状边缘360°金属脚边的PFM,而边缘适合性差者较适合性好者牙龈病变发生率显著增高.结论：后牙PFM的边缘采用羽状边缘360°金属脚边是一种好的选择.     

羟基磷灰石义眼台作为药物缓释载体减轻术后反应的临床观察

目的评价羟基磷灰石（HA）义眼台作为药物缓释载体减轻眼球摘除义眼台植入术后反应的效果。方法植入HA义眼台前，用地塞米松5mg，庆大霉素8万u，透明质酸酶1500U混合液浸泡HA义眼台15—20min后植入，手术步骤按常规。结果观察术后1周反应情况，52例中51例（98．07％）无疼痛或仅有轻度疼痛；44例（84．62％）结膜无水肿；36例（69．23％）无恶心；16例（30．77％）轻中度恶心；48例（92．31％）无呕吐。与对照组（43例）比较，术后疼痛、结膜水肿、恶心呕吐均较轻，其差别均有统计学意义（P〈0．001）。结论HA义眼台作为药物缓释载体植入眼球肌膜囊内能有效地控制术后反应，减轻患者痛苦。

The relationship between maternal needs and priorities in a neonatal intensive care environment

AIM: The aim of this study was to investigate the nature and organization of maternal needs and priorities in a neonatal unit. BACKGROUND: The relationship between maternal needs and priorities appears to be an under studied area in neonatal nursing. METHODS: A quantitative survey was carried out based on 209 mothers with premature infants. Two self-assessment schedules were used: critical care maternal needs inventory (J. Leske, Heart and Lung 15, 27-42) and a ranking scale. The data were analysed with multivariate analysis. FINDINGS: Data analysis revealed clear priorities in maternal needs. In particular the need for accurate infant related information was a priority for 93% of the mothers. Good communication practices with professionals were also valued. The mothers displayed altruistic behaviour, and self-related needs took second place. It is proposed that maternal needs demonstrate a hierarchical organization. CONCLUSION: It is important for nurses to consider the individual needs of the mothers, simply because the satisfaction of these needs is essential for maternal well-being.
