Traumatic brain injury (TBI) could give rise to variable clinical manifestations based on the involved structures of our bodies. Although there are no structural abnormalities proven, the patients with mild TBI suffer from chronic dizziness and imbalance. Herein, I will discuss the visuo-vestibular interaction and neurotological finding in TBI, which could demonstrate the clue to the diagnosis and management in dizzy patients with TBI.

OBJECTIVES: To understand the current status of appraisal of post-concussion syndrome disability and the reasons for the changes in re-appraisal opinions. METHODS: The cases that were judged as "post-concussion syndrome and ten-level disability" in the first appraisal and re-appraised for psychiatric impairment by the Academy of Forensic Science in 2019 were analyzed retrospectively. RESULTS: There were 75 cases, including 58 cases with pre-hospital emergency medical records, among which 39 cases were clearly recorded to be without a history of coma; 74 cases had emergency medical records, among which 44 cases were recorded of having a history of coma; 43 cases had follow-up medical records, among which 24 cases had a history of psychiatric follow-up. The most complained symptoms of the appraisee in appraisal and examination include headache, dizziness, poor sleep at night, irritability, memory loss, fatigue and inattention. The main reasons for the re-appraisal application include doubts about the history of coma, doubts about the credibility of mental symptoms, post-concussion syndrome didn't meet the disability criteria, and objections to the original appraisal procedure or the original appraisal agency. The appraisal opinions of a total of 47 cases were changed. Seven of them did not meet the disability criteria, and the main reason was that there was no clear history of coma and no head injury was admitted; the coma history of the 40 other cases had to be confirmed by the court before they can be clearly identified as disabilities. The reason was that the records about the history of coma were inconsistent or there were alterations and additional information. CONCLUSIONS In the past, the conditions for appraisal of post-concussion syndrome disability were too lax and must be further standardized and strictly controlled.

Behcet disease (BD) is rare in childhood. We report a 9-year-old boy with neuro-Behcet disease who presented diplopia and weakness on the left side after a cerebral concussion. Brain magnetic resonance imaging (MRI) revealed hyperintensity of the right mesodiencephalic junction on T2-weighted and fluid attenuated inversion recovery images. Prednisolone administration resulted in complete remission and normalization of abnormal MRI finding. Brain MRI is a useful diagnostic tool when the neurological sign is the first symptom of subclinical BD.

Mild traumatic brain injury (MTBI) is defined as a mild brain trauma resulting in a short loss of consciousness and alteration of mental status. It may also occasionally develop persistent and progressive symptoms. It has been confirmed that MTBI causes changes of anatomic structures in central nervous system and biomarkers in the body fluid. However, there is no sufficient research on relevance among threshold for the brain injury, individual vulnerability and duration of disturbance of consciousness. Furthermore, there are no reliable diagnostic methods to establish whether a blow to the head is sufficient to cause the brain injury. This review provides references for biomarkers in cerebrospinal fluid and blood associated with TBI. It also provides application status and potential prospects for further assessment and diagnosis of MTBI.

We analyzed the multifractal singularity spectrum of synchronous 12-lead ECG (electrocardiogram) signals from heart and brain disease patients, and found that multifractal curves of different leads do not overlap each other. After calculating the scope of the singularity strength, we noticed that the averages of scope are not the same in different subjects,and the dispersing degree is also different in someone's different leads. Both the deltaalpha, the average of the deltaalpha, and the dispersing degree deltaalpha (be defined as standard deviation) of the deltaalpha of every one's 12-lead ECG were computed. Then, a comparison was made between the spectrum of the healthy subjects and the heart disease patients. The results showed that their deltaalpha are close, but their deltaalpha are markedly different. Also the healthy subjects and brain disease patients were compared, we found that their deltaalpha are close, but their deltaalpha are markedly different. These indicate that the character of multifractal spectrum is controlled by both the neurosystem of body and the self-syntonic property of cardiac structures. Furthermore, the deltaalpha is related with the neuroautonomic control of people's body on the ECG, and the deltaalpha is related with the anisotropy of the heterogeneous tissue and the electric signal propagation in heart.

The ‘white-eyed’ blowout fracture is an orbital injury in children that is often initially misdiagnosed as a head injury because of predominant autonomic features and lack of soft tissue signs. Delays in treatment can lead to morbidity. It has been recommended that children who present with a ‘white-eyed’ blowout fracture should have surgery performed within 48 hours of diagnosis, otherwise prognosis is poor. We present a 12-year-old boy who was initially misdiagnosed with a head injury due to the minor appearance of his orbital injury and his presenting complaints of nausea and vomiting.

PURPOSE: There are two theories about the relationships between facial fractures and cranial injuries. One is that facial bones act as a protective cushion for the brain, and the other is that facial fractures are the marker for increased risk of cranial injury. They have been debated on for many years. The purpose of this study is to identify the relationship between facial fractures and cranial injuries. METHODS: A retrospective study was performed on 242 patients with facial fractures. The data were analyzed based on the medical records of the patients: age, gender, cause of injury, Injury Severity Score (ISS), alcohol intake, type of facial fractures, and type of cranial injury. The patients were divided into two groups: facial fractures with cranial injury and facial fractures without cranial injury. We compared the general characteristics between the two groups and evaluated the relationship between each type of facial fracture and each type of cranial injury. RESULTS: Among the 242 patients with facial bone fractures, 96 (39.7%) patients had a combination of facial fractures and cranial injuries. Gender predilection was demonstrated to favor males: the ratio was 3:1. The mean age was 36.51+/-19.63. As to the injury mechanism, traffic accidents (in car, out of car, motorcycle) were statistically significant in the group of facial fractures with cranial injury (p=0.038, p=0.000, p=0.003). The ISS was significant, but alcohol intake was not significant. No significant relationship between facial fractures and skull fractures was found. Only maxilla fractures, zygoma fractures, and cerebral concussion had a significant difference in cranial injury (p=0.039, p=0.025). CONCLUSION: There is a no correlation between facial fractures and skull fractures, which suggests that the cushion effect is the predominent relationship between facial fractures and cranial injuries.
