Liability for infectious diseases in day care: legal and practical considerations

A lawsuit directed by parents at a day care program following an outbreak of infectious disease would most likely be based on the legal theory of negligence--the failure to exercise due care as required by circumstances. In the determination of liability for infectious diseases in child day care, the element of causation is most critical. Did the day care facility's actions or failure to act cause the harm? Another important question is whether an infectious disease can be occupational and under what circumstances. Although worker's compensation laws initially had no provisions for occupational disease, now all states recognize responsibility for them. Awareness of potential problems with legal liability and establishment of procedures to minimize risk are important for day care providers, public health officials, clinicians, and parents.     

Factors affecting Adolescents' behavior and attitudes toward destructive rock lyrics

In a study of rock music preferences, listening/watching behavior, and views on destructive rock lyrics, 894 adolescents in grades 9 through 12 in rural, urban, suburban public, and metropolitan parochial schools were administered a questionnaire. Demographic information on parents was also collected. It was found that 17.5% of the students were fans of rock music with lyrics that promote homicide, suicide, or satanic practices (HSSR). Loglinear and multiple regression analyses were used to analyze the data. Parents' marital status, student sex, race, and school environment (urban, rural, suburban, etc.) were found to be significant predictors of HSSR status. As compared with non-HSSR fans, the HSSR fans were more likely to have parents who were “Never married” or “Remarried” and less likely to have parents in the “married” category. The HSSR fans were more likely to be male, white, and enrolled in urban schools but not parochial schools than expected; HSSR status also significantly predicted other music-related attitudes and behaviors. The HSSR fans reported liking both the sound and the lyrics of rock music more often than did non-HSSR fans, as did females and urban students. The HSSR fans more often felt that children under 10 years of age should be allowed to listen to HSSR lyrics, and they more frequently expressed the conviction that HSSR music does not affect adolescents' homicidal or self-destructive behavior. The HSSR fans and females reported more nearly complete knowledge of lyrics than did non-HSSR fans and males. The HSSR fans reported that they watch more MTV than did any other group except rural students.     

Patient education: history, development, and current directions of the American Cancer Society and the National Cancer Institute

With their unique perspectives in the identification, design, promotion, and evaluation of cancer patient education programs and services, the National Cancer Institute and the American Cancer Society have the abilities to meet a wide variety of cancer patient education needs. With federal support and connections to national organizations and the comprehensive and clinical cancer center networks, the National Cancer Institute has access to nationwide experts in medical care and the resources to develop, design, and promote quality, state-of-the-art education programs. The American Cancer Society, with its strong volunteer community base, can pull together local expertise and collaborate with local organizations to meet the special needs of local population groups. In addition, the American Cancer Society volunteer committees have the flexibility to individualize programming and resources to answer specific patient/family education problems. As the number of people affected by cancer continues to raise, and as organizations realize the need to maximize their resources with collaborative efforts, the National Cancer Institute and the American Cancer Society are challenged to focus their energies on the patient education initiatives that build upon and combine their unique strengths.     

An examination of social typologies in autism

A system proposed by Wing and coworkers for subtyping autistic individuals on the basis of social interaction is examined in 78 autistic, 39 atypical, and 32 nonautistic, developmentally disordered individuals. Clinical ratings and questionnaire data based on the proposed subtypology were employed. Clinicians were able to reliably group both autistic and nonautistic cases into the three subtypes; these subtypes were strongly related to IQ. Issues relating to the validity and utility of this subtypology are discussed.     

一项对原发进行性多发性硬化症患者认知功能的纵向研究

有关多发性硬化症患者认知功能的纵向研究很少，并且上述研究的结果也不明确，迄今尚无专门关于原发进行性多发性硬化症（PPMS）病例系列的连续神经心理学资料。横断面分析揭示，PPMS患者的认知功能与磁共振成像（MRI）参数之间显著相关。本研究持续2年时间对来源于5个欧洲中心的99例PPMS患者的认知功能和MRI改变进行探讨。采用简易可重复问卷（一种推理能力测试）和抑郁量表每隔12个月对患者进行评估，同时在每个时间点对T1低信号负荷、T2损伤负荷和部分脑体积的MRI参数进行测算。基线和2年时患者的平均认知功能得分间无显著差异。然而，1／3患者的单独测试得分表现出绝对的认知功能下降。研究结果提示，纳入研究时的初始认知状态是2年后认知能力的一个可靠预测指标。认知功能改变和MRI改变间仅有少数几项指标显著相关，值得一提的是T1低信号负荷与2项注意力测试任务相关（r=-0．266，P=0．017；r=-0．303，P=0．012），可能是由多种因素造成认知功能和MRI参数间的这种弱相关。
