Risk factors related to mental disorder in patients with craniocerebral injury / 中华流行病学杂志

Objective To explore the correlation between mental disorder and craniocerebral injury,and notifying its related risk factors.Methods 342 patients from Sep.2008 to Sep.2012 with craniocerebral injury were selected and related clinical data on general their conditions,including sex,age,educational level,satisfaction on careers and relations to family were collected.All the patients received CT-scans to the head,IQ test,MQ test,SCID-1/P,PDQC and SCICP detection.Multivariate logistic regression was used to analyze the general information and cerebral injurious conditions of patients regarding the incidence of mental disorders.Results 249 patients with mental disorder were noticed out of the total 342 patients with craniocerebral injury,with the incidence rate as 72.8％ including 117 depression (47.0％),95 anxiety disorders (38.2％),27 mania (10.8％),69 intelligence and memory disorders (27.7％) cases.Data from correlation analysis showed that factors as sex,age,educational level,satisfaction on careers and family of patients as well as type,severity and location of the craniocerebral injuries appeared to have important correlation with mental disorder.Results also showed that the age of patients (OR ＞ 1.04),severity and location of the craniocerebral injuries (OR1 ＞1.28,OR2＞ 1.31) were independent risk factors (P＜0.05).Conclusion The age of patients,severity and location of the craniocerebral injuries were independent risk factors for mental disorder in patients with craniocerebral injury.

Disability identification for cases with clinical diagnosis of diffuse axonal injury due to traffic accidents: a study of 89 cases / 法医学杂志

OBJECTIVE@#To study the disability identification for cases with clinical diagnosis of diffuse axonal injury (DAI) due to traffic accidents, and to explore the possible effects of DAI on identification results.@*METHODS@#Five hundred and fifty-six cases of cerebral injury due to traffic accidents were collected, including 467 cases diagnosed with cerebral contusion or laceration and 89 cases diagnosed with DAI. The identification results of different groups with diagnosis of DAI diagnosis, diagnosis of DAI with cerebral contusion (laceration), and diagnosis of cerebral contusion or laceration without DAI were compared and statistically analyzed, based on the results of CT and MRI re-review.@*RESULTS@#The disability identification levels in DAI group (20 cases), DAI group (69 cases) with cerebral contusion (laceration) and DAI group (467 cases) not complicated by cerebral contusion (laceration) were 7.72 +/- 1.09, 7.78 +/- 1.11, and 8.86 +/- 0.66, respectively. The disability levels of the two groups diagnosed with DAI were higher than those of the group without DAI diagnosis (P < 0.05).@*CONCLUSION@#Patients with DAI diagnosis might have more severe cerebral injury. In the identification process, one should pay attention to the possible missed diagnosis and misdiagnosis, and meanwhile avoid relying on those evidences provided only by CT and MRI.

Related analysis of mental disability and retardation due to traffic brain injury / 法医学杂志

OBJECTIVE@#To analyze the relevant factors of determining the degree of mental disability after brain injuries in the traffic accidents.@*METHODS@#A total of 157 forensic psychiatry cases involving the assessment of mental disability caused by traffic accidents were collected and divided into three groups (mild, moderate and severe) according to the conclusion of the forensic identification. The demographic, clinical and forensic data were compared in the three groups and analyzed with ordinal logistic regression.@*RESULTS@#There was no statistically significant difference in the demographic data among three groups (P > 0.05). While there was statistically significant difference in the coma duration, severity of intracranial hemorrhage, working capacity, family duties, social functions, self care capacity and intelligence quotient (P < 0.05) among the groups. Intracranial hemorrhage, family duties, social functions and self care capacity were chosen as the factors in the logistic regression equation.@*CONCLUSION@#The degree of the brain damage influenced the mental disability. Family duties, social functions and self care capacity are the major factors for determining the degree of mental disability after injured.
