Objective:To compare the clinical outcomes of immediate breast reconstruction using latissimus dorsi flap with implant versus mesh with implant based on BREAST-Q evaluation.Methods:From the clinical database of the First Affiliated Hospital of Nanjing Medical University, the patients who underwent immediate breast reconstruction after total mastectomy from January 2020 to December 2023 were selected as the research subjects. All breast reconstruction surgeries were performed by the same surgeon. Patients were divided into two groups according to surgical methods: the latissimus dorsi muscle flap combined with implant immediate breast reconstruction group (LD group) and the mesh combined with implant immediate breast reconstruction group (mesh group). Patients were followed up in outpatient clinics or by telephone one year after surgery. The BREAST-Q was used to evaluate the surgical outcomes of both groups from four dimensions: psychosocial well-being, sexual well-being, chest-physical well-being, and breast satisfaction. The score range for each dimension was 0-100, with higher scores indicating greater patient satisfaction with quality of life and surgical outcomes. Statistical analysis was performed using SPSS 22.0 software. Normally distributed measurement data were expressed as Mean ± SD, and comparisons between the two groups were performed using independent sample t-test. Count data were expressed as number of cases and percentages, and comparisons between groups were performed using chi-square test or Fisher’s exact test. P<0.05 was considered statistically significant. Results:A total of 123 patients were included, with 59 patients in the LD group and 64 patients in the mesh group. In the LD group, the mean age was (37.7±7.0) years, body mass index (BMI) was (22.6±2.6) kg/m 2, and clinical tumor staging showed 2, 22, 30, and 5 cases for stages 0, Ⅰ, Ⅱ, and Ⅲ, respectively. In the mesh group, the mean age was (39.1±7.0) years, BMI was (22.6±2.8) kg/m 2, and clinical tumor staging showed 1, 25, 38, and 0 cases for stages 0, Ⅰ, Ⅱ, and Ⅲ, respectively. There were no statistically significant differences between the two groups in baseline characteristics including age, BMI, and clinical tumor staging (all P>0.05). One year after surgery, the BREAST-Q result showed no statistically significant differences between the LD group and mesh group in psychosocial well-being [(83.0±19.8) points vs. (80.8±19.3) points] and sexual well-being [(62.1±30.4) points vs. (65.8±25.6) points] (all P>0.05). However, the LD group had lower chest-physical well-being scores than the mesh group [(40.6±9.7) points vs. (45.1±9.6) points, P<0.05], while breast satisfaction scores were higher in the LD group than in the mesh group [(68.0±17.8) points vs. (59.8±12.6) points, P<0.01]. Conclusion:Immediate breast reconstruction by both latissimus dorsi flap with implant and mesh with implant can improve patients’ psychosocial and sexual well-being by enhancing breast appearance. However, LD technique provides better breast satisfaction, while the mesh technique offers advantages in physical well-being of the chest wall and upper body. Surgeons should select the most appropriate breast reconstruction technique based on patients’ anatomical conditions, treatment history, and individual needs to optimize postoperative quality of life and satisfaction.

Objective This study aims to investigate controversial cases of forensic clinical re-identification of fractures,exploring the characteristics,causes,and countermeasures related to identification errors in primary bone injuries,complications,and subsequent changes.The goal is to provide identification strategies for similar cases regarding the collection of identification materials,timing,and examination method selection,ultimately establishing a paradigm for such identifications.Methods A total of 103 cases of clinical re-identification of fractures accepted by the West China Forensic Identification Center from 2020 to 2024 were collected,and the data from initial identifications and re-identifications were retrospectively analyzed.Results Male cases accounted for 69.90%of the re-identifications,with disability grade(67.96%)and injury degree(30.10%)being the primary concerns.Individual requests represented a high proportion(92.86%)in the initial assessment of disability levels,while unit or joint requests dominated the re-assessment(92.86%).The agreement rates for disability grade and injury degree were 55.26%and 59.38%,respectively.The reassessment of disability grades primarily involved fractures of limb long bones,spine,and ribs,with 75.53%of opinions resulting in downgraded disability levels.Rib,orbital,and nasal bone fractures were the main focus in injury degree reassessments,with 84.62%of opinions indicating aggravated injuries.The consistency rates for fracture identification in disability grade assessments was 92.21%,while rates for injury degree and sequelae were 65.63%and 48.94%,respectively.Inconsistencies in identifying damage facts—including the presence of fractures,distinguishing between fresh and old fractures,and determining the nature of fractures and sequelae—were primarily noted in rib,orbital,and nasal bone fractures.The utilization rate of CT metadata in initial evaluations(25.00%)was significantly lower than in re-evaluations(95.00%).The identification time for joint mobility dysfunction after fracture in re-identifications was significantly longer than in initial identifications(P=0.0002),and the identification time for cases with agreement was significantly shorter than for cases with disagreement(P=0.036).Conclusion Image data type and identification timing are critical factors that may influence the accuracy and consistency of forensic clinical identification of bone injuries.When necessary,dynamic CT metadata in conjunction with image post-processing technology can be routinely employed to identify fractures of the ribs,orbital bones,or nasal bones,thereby reducing the risk of misidentification.

Objective:To investigate the clinical manifestations of medically refractory hereditary movement disorders in children and the efficacy of deep brain stimulation (DBS).Methods:A case series study.The clinical and follow-up data of 20 children with medically refractory hereditary movement disorders who underwent DBS treatment at the Neurology and Functional Neurosurgery Departments of Beijing Children′s Hospital, Capital Medical University, from July 2018 to April 2024, were retrospectively analyzed.The severity of movement disorder symptoms and surgical effects were evaluated using the Burke-Fahn-Marsden Dystonia Rating Scale Movement(BFMDRS-M) or the Unified Parkinson′s Disease Rating Scale Ⅲ(UPDRS Ⅲ).Results:There were 12 males and 8 females among the 20 children, with an onset age ranging from 4 months to 12 years and 5 months.Fourteen patients had hereditary dystonia, which is related to KMT2B in 11 patients, TOR1A in 2 patients and SGCE in 1 patient.Two patients had choreoathetosis, which is related to ADCY5-related familial movement disorders.Two patients had early-onset Parkinson′s disease, which is related to ATP6AP2 in 1 patient and VPS13C in 1 patient.Two patients had neurodevelopmental disorders with involuntary movements, which is related to GNAO1 in 1 patient, and the other patient was idiopathic.All the children were given oral Levodopa, Benzhexol, Baclofen, Tiapride Hydrochloride, Clonazepam alone or in combination.Three children showed obvious dyskinesia after Levodopa treatment.The symptoms of movement disorders in all children exhibited little to no improvement.Levetiracetam and Zonisamide had unstable effects in the treatment of myoclonia.DBS surgery was performed on all the patients aged from 3 to 16 years.Electrodes were successfully inserted into bilateral globus pallidus internus in 14 cases and bilateral subthalamic nuclei in 4 cases.The target was unknown in 2 cases.No surgery-related complications were observed.The patients were followed up for 3 months to 6 years, and the last follow-up age of the patients ranged from 5 years and 7 months to 22 years and 1 month.The rate of improvement in BFMDRS-M score was 37%-100% in 16 patients and >70% in 7 patients with hereditary dystonia.The rate of improvement in UPDRS Ⅲ score was 23% in 1 patient with VPS13C-related early-onset Parkinson′s disease. Conclusions:Childhood medically refractory hereditary movement disorders are a case series that exhibits significant phenotypic and genotypic heterogeneity.DBS surgery demonstrates significant efficacy for KMT2B-, TOR1A-, and SGCE-related hereditary movement disorders.

Dravet syndrome is a epileptic syndrome characterized by drug-resistant epilepsy occuring at childhood. It is often accompanied by status epilepticus and cognitive and language impairment appearing gradually as the disease progresses. The effect of antiepileptic drugs and resection epilepsy surgery on Dravet syndrome is poor although neuromodulation surgery, especially vagus nerve stimulation, is an effective and feasible treatment for Dravet syndrome. In this article we reported a case of Dravet syndrome treated with vagus nerve stimulation, relevant literature was reviewed and summarized at the same time. A total of 141 cases of Dravet treated by vagus nerve stimulation were collected, and the overall effective rate was 53.9%.

Objective:To summarize the clinical characteristics of children with dystonia 28 (DYT28) caused by KMT2B gene variations so as to improve clinicians′ understanding of the disease. Methods:The clinical manifestations, treatment and gene variation data of 11 children with DYT28 caused by KMT2B gene variations were retrospectively collected and analyzed.The subjects were recruited from the Department of Neurology, Beijing Children′s Hospital, Capital Medical University from March 2018 to January 2021.The patients were followed up. Results:There were 8 males and 3 females.The age at onset was ranging from 1 month to 6 years without inducement.Eight cases were gene-ralized dystonia and 3 cases were multifocal dystonia.The initial symptoms of 7 cases were unilateral or bilateral lower limbs tiptoeing.Four cases presented dysarthria, retching or swallowing difficulties at onset.As the disease progressed, all the cases had laryngeal dystonia, 10 cases had lower limbs dystonia, and 8 cases had upper limbs dystonia.Six cases were complicated with other dyskinesia symptoms.Ten cases had varying degrees of short stature, microcephalus, micrognathia, musculoskeletal abnormalities, intellectual disability, endocrinopathies and sleep difficulties.The brain magnetic resonance imaging showed abnormal in only 1 case.Eleven KMT2B gene pathogenic variants were found, including 8 frameshift variants, 1 in-frame variant and 2 missense variants.Four variants were novel.Eleven cases were followed up at the age of 1 year and 7 months to 17 years and 9 months.One case wasn′t given therapy.The dystonia in 3 cases was mildly improved after medication.Dysfunction of urination and defecation was disappeared in 1 case after medication.The symptom of 6 cases had no improvement after drug therapy.Among the above 6 cases, 5 drug refractory cases had deep brain stimulation, and their dystonia symptoms are all obviously improved; 2 cases had normal control of urination and defecation after deep brain stimulation.The motor scores in the Burke-Fahn-Marsden dystonia rating scale were improved by 55.8%-90.7%, and the disability scores were improved by 14.8%-69.6%. Conclusions:DYT28 caused by KMT2B gene variations is one of the most common and early-onset genetic dystonia in children.The dystonia symptom progresses from local parts to the whole body, prominently involving laryngeal muscles and lower limbs.Control of urination and defecation requires attention.Patients with mild dystonia symptoms can be effectively treated by drugs.However, patients with severe dystonia symptoms were drug refractory, and their dystonia symptoms can be effectively improved by deep brain stimulation.

Objective To investigate the influencing factors for rebleeding after gastroscopy in patients with liver cirrhosis and esophagogastric variceal bleeding. Methods A retrospective analysis was performed for the clinical data of the patients with liver cirrhosis and esophagogastric variceal bleeding who were hospitalized in Tianjin Third Central Hospital from January 1, 2017 to December 31, 2018, and according to the presence or absence of rebleeding and bleeding time, the patients were divided into non-bleeding group ( n =148) and bleeding group ( n =119). The risk factors for rebleeding after gastroscopy were analyzed. The t -test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The Cox regression model was used for univariate and multivariate analyses. The receiver operating characteristic (ROC) curve was used to evaluate the accuracy of Child-Turcotte-Pugh (CTP), fibrosis-4 (FIB-4), and albumin-bilirubin (ALBI) scores in predicting rebleeding after gastroscopy, and MedCalc was used to compare the area under the ROC curve (AUC). Results A total of 267 patients with liver cirrhosis and esophagogastric variceal bleeding were enrolled, among whom 53 (19.9%) had liver cancer. A total of 119 patients suffered from rebleeding, with an overall rebleeding rate of 44.6% and a median time to rebleeding of 11.0 (0-39.0) months. The univariate Cox regression analysis showed that liver cancer (hazard ratio [ HR ]=0.377, P < 0.001), aspartate aminotransferase (AST) ( HR =1.002, P =0.025), serum Na ( HR =0.935, P =0.004), and FIB-4 ( HR =1.030, P =0.049) were associated with rebleeding, and the multivariate Cox regression analysis showed that liver cancer ( HR =0.357, P < 0.001), AST ( HR =1.003, P =0.030), prothrombin time (PT) ( HR =0.196, P =0.001), CTP score ( HR =1.289, P =0.014), FIB-4 ( HR =1.062, P =0.033), and ALBI score ( HR =0.433, P =0.011) were independent risk factors for rebleeding. CTP, FIB-4, and ALBI scores had an AUC of 0.711 (95% confidence interval [ CI ]: 0.647-0.776), 0.705 (95% CI : 0.640-0.770), and 0.730 (95% CI : 0.667-0.793), respectively, in predicting rebleeding. There was no significant difference in AUC between CTP, FIB-4, and ALBI scores ( P > 0.05). Conclusion Liver cancer, AST, PT, CTP score, FIB-4 score, and ALBI score are associated with rebleeding after gastroscopy in patients with liver cirrhosis and esophagogastric variceal bleeding, among which CTP, FIB-4, and ALBI scores have a good value in predicting rebleeding outcome, while there is no significant difference in predictive ability between them.
