Objective:To compare the effectiveness of different durations of anti-seizure medications for acute symptomatic seizures in children with acute encephalitis syndrome.Methods:A total of 186 children with acute symptomatic seizures who received treatment at the Department of Neurology, Xi 'an Children's Hospital, from May 2020 to May 2022 were retrospectively included in this study. All patients were treated with anti-seizure medications. These children were divided into an observation group ( n = 93, 4-week anti-seizure medication) and a control group ( n = 93, 12-week anti-seizure medication) according to different durations of anti-seizure medication they received. The abnormal rates of electroencephalogram findings, treatment effectiveness, and recurrence rates of epileptic seizures were compared between the two groups. These children were divided into a recurrent group and a non-recurrent group based on their seizure recurrence outcomes. Clinical data from both groups were collected and compared. The factors influencing the recurrence of epileptic seizures were analyzed. Results:There were no significant differences in abnormal rates of electroencephalogram findings, treatment effectiveness, and recurrence rates of epileptic seizures between the observation and control groups (χ 2 = 1.90, 0.98, 0.36, all P > 0.05). Among the 186 children who were followed up for 1 year, epileptic seizures recurred in 12 cases, while 174 cases did not experience any recurrence. Univariate analysis revealed statistically significant differences between the recurrent and non-recurrent groups in terms of consciousness status, electroencephalogram findings, and Pediatric Cerebral Performance Category scores (χ2 = 6.16, 4.40, 5.88, all P < 0.05). Further analysis using binary logistic regression identified severe coma and Pediatric Cerebral Performance Category scores of 3-4 as independent risk factors for recurrent seizures in children with acute symptomatic seizures (both P < 0.05). Conclusion:Four-week and twelve-week anti-seizure medication for acute symptomatic seizure in children show similar effectiveness. Severe coma and Pediatric Cerebral Performance Category scores of 3-4 are significantly correlated with the recurrence of acute symptomatic seizure and therefore require clinical attention.

OBJECTIVE: To summarize the etiology mechanism and treatment of iatrogenic blepharoptosis after double eyelid surgery in Asia. METHODS: To extensively review the literature related to iatrogenic blepharoptosis after double eyelid surgery, and to summarize and analyze the related anatomical mechanism, existing treatment options, and indications. RESULTS: Iatrogenic blepharoptosis is a relatively common complication after double eyelid surgery, sometimes it is combined with other eyelid deformities such as sunken upper eyelid and wide double eyelid, which makes it difficult to repair. The etiology is mainly caused by improper adhesion of tissues and scars, improper removal of upper eyelid tissue, and injury of a link of levator muscle power system. Whether blepharoptosis occurs after double eyelid surgery by incision or suture, it should be repaired by incision. The principles of repair include surgical loosening of tissue adhesion, anatomical reduction, and repair of damaged tissues. The key is to use surrounding tissues or transplanted fat to prevent adhesion. CONCLUSION When repairing iatrogenic blepharoptosis clinically, appropriate surgical methods should be selected based on the causes and severity of the blepharoptosis, combined with treatment principles, in order to achieve better repair results.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
