摘要
法医学中的死后计算机断层扫描(PMCT)不仅有助于案件工作,也是其他成像研究(如骨骼形态研究)的有用数据源。PMCT 三维数据可与诊断信息相结合,有助于阐明疾病在体内的表现形式。例如,骨骼会受到发育不稳定性的影响,这可能导致一种称为波动不对称(FA)的形态变化。发育不稳定性也会影响患精神分裂症的风险,这意味着发育不稳定性较高的人患精神分裂症的风险可能较高,进而影响到波动不对称。这种联系已在软组织中进行过研究,但尚未在骨骼中进行过研究。我们利用法医队列中的 PMCT 3D 模型,比较了一组确诊精神分裂症患者与对照组之间的颅骨 FA 水平。我们的样本包括 48 名确诊精神分裂症患者和 58 名对照组患者。我们从三维模型中收集了 27 个地标。我们使用 Procrustes 方差分析对波动不对称水平进行了分析,并使用 t 检验和 Wilcoxon 秩和检验对两组进行了比较。使用皮尔逊相关性和双向方差分析检验了年龄和性别因素。我们发现,精神分裂症组和对照组的颅骨FA水平差异无统计学意义,年龄和性别都不是影响因素。我们的研究结果证实了早先的研究,这些研究表明,FA 和精神分裂症的多因素病因难以全面把握。
Cranial fluctuating asymmetry and schizophrenia in a contemporary Danish population
Post-mortem Computed Tomography (PMCT) scans in forensic medicine not only assist with case work but is also a useful data source for other imaging-based research, e.g. morphological studies on bones. PMCT 3D data can be combined with diagnostic information and help to elucidate how disease manifests in the body. For example, the skeleton can be influenced by developmental instability, which may result in a morphological change called fluctuating asymmetry (FA). Developmental instability also influences the risk of developing schizophrenia, which means that individuals with higher levels of developmental instability, and by extension FA, might have a higher risk of developing the disorder. This connection has been investigated in soft tissues but has not yet been investigated in bones. We used PMCT 3D models from a forensic cohort to compare levels of cranial FA between a group of individuals with diagnosed schizophrenia and a control group. Our sample included 48 individuals with diagnosed schizophrenia and 58 controls. We collected 27 landmarks from our 3D models. Levels of fluctuating asymmetry were analysed using Procrustes ANOVA, and the two groups were compared using t-test and Wilcoxon rank sum test. Age and sex were tested as factors using Pearson correlation and two-way ANOVA. We found that there was no statistically significant difference in levels of cranial FA between the schizophrenic group and the control group, and that neither age nor sex was a factor. Our results confirm earlier studies that suggest that the multifactorial aetiology of FA and schizophrenia is difficult to capture comprehensively.
