用生物心理社会医学模式指导疾病的诊治

惊恐障碍作为一种精神科疾病,由于伴有明显的躯体化症状,使大多患者首诊于综合医院非精神科,极易引起该病的误诊误治,同时也浪费了大量的卫生资源.针对这一情况,本期"临床决策研究"栏目中熊新英撰写的"从惊恐障碍看生物心理社会医学模式的必要性和紧迫性",对于惊恐障碍就诊于综合医院误诊率高的原因及高误诊率导致的后果进行了分析,并提出了相应的对策.     

客观全面地认识和治疗疾病

本期"临床决策研究"栏目由杨宁等撰写的"客观认识心脏介入治疗"对目前心脏介入治疗进行了客观评价和反思,认为目前由于医疗卫生体制不完善,医疗机构过分追求经济效益等因素的影响,使心脏介入治疗技术出现了偏差,文章指出心脏介入治疗的应用,应该严格把握适应证,社会效益与经济效益相结合,在配备好的硬件设施的同时,更要重视软件的培养,作者强调应用心脏介入治疗技术治疗心脏疾病,必须将自然科学和社会科学结合起来,用最恰当、最合适的诊治方案为患者去除病痛."     

Face engagement during infancy predicts later face recognition ability in younger siblings of children with autism

Face recognition difficulties are frequently documented in children with autism spectrum disorders (ASD). It has been hypothesized that these difficulties result from a reduced interest in faces early in life, leading to decreased cortical specialization and atypical development of the neural circuitry for face processing. However, a recent study by our lab demonstrated that infants at increased familial risk for ASD, irrespective of their diagnostic status at 3 years, exhibit a clear orienting response to faces. The present study was conducted as a follow‐up on the same cohort to investigate how measures of early engagement with faces relate to face‐processing abilities later in life. We also investigated whether face recognition difficulties are specifically related to an ASD diagnosis, or whether they are present at a higher rate in all those at familial risk. At 3 years we found a reduced ability to recognize unfamiliar faces in the high‐risk group that was not specific to those children who received an ASD diagnosis, consistent with face recognition difficulties being an endophenotype of the disorder. Furthermore, we found that longer looking at faces at 7 months was associated with poorer performance on the face recognition task at 3 years in the high‐risk group. These findings suggest that longer looking at faces in infants at risk for ASD might reflect early face‐processing difficulties and predicts difficulties with recognizing faces later in life.
