Objective: This study examined the characteristics of patients with cervical spine injuries caused by industrial accidents and analyzed the factors related to mortality. Methods: In total, 424 patients with cervical spine injuries who visited our hospital from 2016 to 2020 were divided into an industrial accident and non-industrial accident groups. Age, sex, fracture severity, facet injury, high cervical injury, spinal epidural hematoma, spinal cord injury, shock, arrival route, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), mortality, and trauma mechanism were compared between the two groups. Regression analysis was performed to determine the factors affecting mortality. Results: Industrial accident patients significantly differed from the rest of the study population in terms of the sex ratio (male ratio, 95.1% vs. 77.8%; p<0.001), arrival route (direct transport, 61.2% vs. 50.9%; p=0.017), and trauma mechanism (p<0.001). Among the trauma mechanisms, falls had the largest difference between industrial accident patients and all patients (55.3% and 28.1%, respectively). Significant associations with mortality were found for falls (odds ratio [OR], 22.330; p=0.015), ISS (OR, 1.056; p=0.008), GCS <9 (OR, 0.014; p<0.001), and shock (OR, 7.290; p<0.001). Conclusion: Falls were the most frequent trauma mechanism of cervical spine injuries in patients who experienced industrial accidents. The factors significantly correlated with mortality were falls, ISS, GCS <9, and shock.
目的:探讨工业事故颈椎损伤患者的特点，分析其死亡的相关因素。方法:将2016 - 2020年在我院就诊的424例颈椎损伤患者分为工伤组和非工伤组。比较两组患者的年龄、性别、骨折严重程度、小关节面损伤、高位颈椎损伤、脊髓硬膜外血肿、脊髓损伤、休克、到达途径、损伤严重程度评分(ISS)、格拉斯哥昏迷评分(GCS)、死亡率、创伤机制。采用回归分析确定影响死亡率的因素。结果:工业事故患者在性别比例方面与其他研究人群存在显著差异(男性比例，95.1% vs. 77.8%;P <0.001)，到达途径(直达交通，61.2% vs. 50.9%;P =0.017)，创伤机制(P <0.001)。工伤事故患者与所有患者的创伤机制中，跌倒的差异最大(分别为55.3%和28.1%)。跌倒与死亡率有显著相关性(优势比[OR]， 22.330;p=0.015)， ISS (OR, 1.056;p=0.008)， GCS <9 (OR, 0.014;p<0.001)，休克(OR, 7.290;p < 0.001)。结论:跌倒是工业事故颈椎损伤最常见的外伤机制。与死亡率显著相关的因素是跌倒、ISS、GCS <9和休克。

Segmental zoster paresis (SZP) of the limbs, characterized by focal weakness of the extremity, is recognized as a rare complication of herpes zoster that can lead to a misdiagnosis of other radiculopathies or musculoskeletal problems. Here, we present a rare case where the patient experienced severe pain and weakness of the right upper extremity caused by SZP. A 58-year-old man came to the hospital with severe right upper extremity radicular pain. Cervical magnetic resonance imaging of the spinal cord showed disc protrusion at the C5-6 level with a high signal change. Anterior cervical discectomy and fusion was performed. On the first and second postoperative days, the patient’s symptoms showed slight improvements. However, on the fourth postoperative day, the patient experienced a right shoulder drop along with exacerbated radicular pain and presented a herpetic rash on the right extremity. The patient showed a dramatic improvement in pain and weakness after taking antiviral medication and undergo-ing a fluoroscopic-guided right C6 selective nerve root block. He fully recovered from his symptoms after 12 weeks of rehabilitation and physical therapy. This rare case involved SZP which was misunderstood as a herniated cervical disc. If a patient complains of severe pain with motor weakness inconsistent with radiologic findings, SZP should be discriminated from other possible diagnosis.

difficult to diagnose because of technical difficulties in performing angiography and the small lesion size. To date, the most appropriate method of treating and diagnos-ing spontaneous spinal hemorrhage due to spinal AVMs with neurological deficits remains un-clear. Herein, we present a rare case of spontaneous vertebral hemorrhage due to a thoracic epidural spinal AVM, which was removed surgically and accurately diagnosed based on a histopathological examination of the lesion. This case emphasizes that an accurate diagnosis and neurological recovery could be achieved in patients with spontaneous spinal epidural hematoma through biopsy and surgical removal of the hematoma and AVM.

arachnoid cyst is rare and not usually located in the tectal plate region. Such a cyst may extend to the surrounding area and compress adjacent structures due to cys-tic expansion. Arachnoid cysts occasionally are associated with hydrocephalus and produce related symptoms. In our case, a 20-month-old boy presented with developmental regression and macrocephaly. Image study of the brain demonstrated a large cyst on the superior portion of the posterior fossa with extension to the supratentorial space and a compressed cerebellum inferiorly and brain stem anteriorly. Lateral and third ventricles were enlarged severely. We performed lateral ventriculo-cystostomy by neuroendoscope via a precoronal approach. Additional third ventriculostomy was performed on the floor of the third ventricle. At 9 months after surgery, the patient showed restored development, and postoperative image showed a reduction of arachnoid cysts and lateral and third ventricles.

Schwannomas are common, slow-growing benign tumors derived from Schwann cells lining the nerve sheath which are rarely developed from the scalp. There are several types of schwannoma; however, ancient schwannoma is a rare benign tumor. We present a case of a 36-year-old man with an approximately 3 × 2-cm palpable mass on the left parietal ar ea of his scalp that slowly grew over 5 years. The tumor was surgically excised and confirmed by immunohistochemistry, indicating an “ancient schwannoma” different from a trichilemmal or dermoid cyst.
