Objective:To summarize the clinical, pathological, and molecular genetic features of dermatofibrosarcoma protuberans (DFSP) in children.Methods:A retrospective analysis was conducted on clinical data from 8 children with DFSP in the Department of Dermatology, Beijing Children′s Hospital, Capital Medical University from January 2017 to December 2024. General information, clinical manifestations, pathological examinations, molecular genetic examinations, and treatments were analyzed, and clinical features and prognosis were summarized.Results:All the 8 cases were females, with ages at onset ( M[ Q1, Q3]) of 1.3 (0.3, 2.6) years, including 2 congenital cases; their ages at diagnosis were 5.1 (3.7, 7.4) years. Skin lesions manifested as solitary dark red patches, plaques, or nodules, and were located on the trunk in 5 cases (3 on the back, 1 on the abdomen, and 1 on the chest) and on the lower limbs in 3 cases. Histopathological examinations of all the 8 cases showed tumor cells diffusely infiltrating the dermis and subcutaneous tissue without epidermal involvement. Immunohistochemical staining showed that all the cases were strongly positive for CD34 and negative for soluble 100 protein; the Ki-67 labeling index ( M[ Q1, Q3]) was 9.0% (8.0%, 17.5%). Fluorescence in situ hybridization revealed the COL1A1-PDGFB fusion gene or PDGFB gene rearrangement in all 8 cases. All the patients underwent surgical excision of the primary skin lesions, including 3 treated with wide local excision, 2 with traditional Mohs surgery, and 3 with modified slow Mohs surgery, and all achieved negative margins. During the follow up of 6 months to 7 years, no tumor recurrence was observed. Conclusions:DFSP often occurred at a relatively young age in children, and mostly presented as atrophic patches or plaques. PDGFB gene alterations were commonly observed, and prognosis after surgical treatment was generally favorable.

OBJECTIVE: A prospective randomized controlled study was conducted to investigate the early postoperative analgesic effectiveness of using liposomal bupivacaine (LB) for local infiltration anesthesia (LIA) in unicompartmental knee arthroplasty (UKA). METHODS: Between January 2024 and July 2024, a total of 80 patients with knee osteoarthritis (KOA) who met the selection criteria were enrolled in the study. Patients were randomly assigned to either the LB group or the "cocktail" group in a 1∶1 ratio using a random number table, with 40 patients in each group. Baseline characteristics, including gender, age, body mass index, operated side, Kellgren-Lawrence grade, and preoperative American Society of Anesthesiologists (ASA) classification, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and knee joint range of motion, showed no significant difference between the two groups ( P>0.05). Both groups received LIA and comprehensive pain management. The surgical duration, incision length, pain-related indicators [resting and activity visual analogue scale (VAS) scores, total dosage of oral morphine, WOMAC scores], knee joint range of motion, first ambulation time after operation, length of hospital stay, and postoperative adverse events. RESULTS: There was no significant difference between the two groups in surgical duration, incision length, first ambulation time after operation, length of hospital stay, total dosage of oral morphine, and pre-discharge satisfaction with surgery and WOMAC scores ( P>0.05). At 4, 12, and 24 hours after operation, the resting and activity VAS scores in the "cocktail" group were lower than those in the LB group; at 60 and 72 hours postoperatively, the resting VAS scores in the LB group were lower than those in the "cocktail" group, with the activity VAS scores also being lower at 60 hours; all showing significant differences ( P<0.05). There was no significant difference in the above indicators between the two groups at other time points ( P>0.05). On the second postoperative day, the sleep scores of the LB group were significantly higher than those of the "cocktail" group ( P<0.05), while there was no significant difference in sleep scores on the day of surgery and the first postoperative day ( P>0.05). Additionally, the incidence of complications showed no significant difference between the two groups ( P>0.05). CONCLUSION The use of LB for LIA in UKA can provide prolonged postoperative pain relief; however, it does not demonstrate a significant advantage over the "cocktail" method in terms of short-term analgesic effects or reducing opioid consumption and early functional recovery after UKA. Nevertheless, LB may help reduce postoperative sleep disturbances, making it a recommended option for UKA patients with cardiovascular diseases and insomnia or other mental health issues.

Objective: Metastases in the supragastric lesser sac (SGLS) are not only occult but are also barriers to complete resection of ovarian cancer. We describe a cohort of patients with SGLS disease undergoing debulking surgery. Methods: We identified all patients who underwent evaluation and eventual resection of SGLS disease as part of cytoreductive surgery for stage IIIC–IVB high-grade epithelial ovarian cancer at our institution from January 2018 to August 2022. Results: Thirty-three of 286 patients (11.5%) underwent resection of SGLS disease.Metastases in the SGLS were identified by preoperative imaging in 4 of 33 patients (12.1%). The median peritoneal cancer index score was 22 (range, 9–33). Through surgical exploration, metastases were frequently seen in the right diaphragm (100%), hepatorenal recess (97%), lesser omentum (81.8%), left diaphragm (78.8%), supracolic omentum (75.8%), anterior transverse mesocolon (72.7%), splenic hilum (63.6%), ligamentum teres hepatis (60.6%), and gallbladder fossa (51.5%). The lesser omentum was normal in 6 of 33 (18.2%) patients, despite metastases within the SGLS. A total of 54.5% of patients underwent complex surgery (surgical complexity scores; median, 8; range, 3–14). Complete resections were achieved in 19 (57.6%) patients. No complications were related to the resection of SGLS disease. The median length of progression-free survival was 24.8 months (95% confidence interval=16.6–32.9). Conclusion Metastases to the SGLS are not uncommon in advanced ovarian cancer, particularly those with widely disseminated disease. Disease in this recess is rarely identified by preoperative imaging and deserves systematic surgical exploration to attain complete cytoreduction.

Background: The Lymphadenectomy in Ovarian Neoplasms (LION) study revealed that systemic lymphadenectomy did not bring survival benefit for advanced ovarian cancer patients with clinically normal lymph nodes and was associated with a higher incidence of operative complications. However, there is no consensus on whether lymphadenectomy has survival benefit or not in early epithelial ovarian cancer (EOC). Methods We designed the LOVE study, a multicenter, randomized controlled, phase III trial to compare the efficacy and safety of comprehensive staging surgery with or without lymphadenectomy in stages IA-IIB EOC and fallopian tube carcinomas (FTC). The hypothesis is that the oncological outcomes provided by comprehensive staging surgery without lymphadenectomy are non-inferior to those of conventional completion staging surgery in early-stage EOC and FTC patients who have indications for post-operative adjuvant chemotherapy. Patients assigned to experimental group will undergo comprehensive staging surgery, but lymphadenectomy. Patients assigned to comparative group will undergo completion staging surgery including systematic pelvic and para-aortic lymphadenectomy. All subjects will receive 3–6 cycles of standard adjuvant chemotherapy. Major inclusion criteria are pathologic confirmed stage IA-IIB EOC or FTC, and patients have indications for adjuvant chemotherapy either confirmed by intraoperative fast frozen section or previous pathology after an incomplete staging surgery. Major exclusion criteria are non-epithelial tumors and low-grade serous carcinoma. Patients with severe rectum involvement which lead to partial rectum resection will be excluded. The sample size is 656 subjects. Primary endpoint is disease-free survival.

Objective To evaluate the effects of spinal manipulation therapy (SMT) on chronic nonspecific neck pain (CNSNP) by using World Health Organization Family International Classifications (WHO-FICs). Methods Randomized controlled trials (RCTs) about the effects of SMT on CNSNP were searched from PubMed, Web of Science, Cochrane Library, EMBASE, EBSCO, CBM and CNKI from database establishment to December 31st, 2021. At least two researchers extracted the data. Cochrane bias risk assessment tool and Physiotherapy Evidence Database Scale were used to evaluate the quality of the included articles. Revman 5.4 software and Stata 16.0 software were used for meta-analyses and publication bias analysis respectively. Results A total of 15 RCTs that represented 1 067 participants were evaluated. In terms of body functions, compared with the control group, SMT significantly reduced Visual Analog Score for pain (MD = -0.85, 95%CI -1.06 to -0.63, P < 0.00001) and Numerical Rating Scale (MD = -0.92, 95%CI -1.29 to -0.55, P < 0.001), increased pressure pain thresholds (SMD = 0.67, 95%CI 0.47 to 0.86, P < 0.001), cervical range of motion (ROM) of flexion/extension (SMD = 0.51, 95%CI 0.33 to 0.68, P < 0.001) and rotation (SMD = 0.20, 95%CI 0.01 to 0.38, P = 0.04), improved root mean square of cervical muscles electromygraphy (MD = 2.17, 95%CI 0.06 to 4.29, P = 0.04), but not significantly in cervical ROM of lateral flexion (SMD = 0.19, 95%CI -0.00 to 0.38, P = 0.06), cervical strength (SMD = -0.18, 95%CI -0.84 to 0.49, P = 0.60) and endurance (SMD = 0.18, 95%CI -0.39 to 0.75, P = 0.53). In term of activities and participation, SMT significantly improved cervical disability (MD = -0.96, 95%CI -1.55 to -0.38, P = 0.001), but not significantly in health status of patients with CNSNP (SMD = 0.08, 95%CI -0.03 to 0.20, P = 0.15). Conclusion SMT could improve pain intensity, pain sensitivity, cervical ROM and disability in patients with CNSNP, but its efficacy on muscle function, proprioception and health status is unclear.

ObjectiveTo conduct a bibliometric analysis of the research status and hot spots of physical fitness for children and adolescents with intellectual disability using CiteSpace. MethodsBased on the theoretical framework of World Health Organization Family of International Classifications (WHO-FICs), literatures about physical fitness for children and adolescents with intellectual disability were searched in PubMed from 2012 to 2022. CiteSpace 6.1.R2 was used to draw knowledge mapping. ResultsA total of 670 literatures were retrieved from PubMed, and 348 literatures were included. The mean number of articles published was 31.6 per year, which presented an upward trend. The characteristics and intervention strategies of physical fitness for children and adolescents with intellectual disabilities, such as Down syndrome, autism spectrum disorder and Prader-Willi syndrome had been the hot spots of research in the past ten years. Under the guidance of the WHO-FICs framework, physical fitness involved structural and functional levels (body composition/obesity, bone health, motor development/motor skills, postural control, etc.), activity and participation levels (physical activity/sedentary behavior, quality of life, etc.), and environmental and personal factors (parental support, etc.). Intervention included physical fitness strategies (aerobic exercise, moderate-to-vigorous physical activity, video games, resistance training, etc.), motor skills training strategies (adaptive physical activity, adaptive physical education, etc.), and sport event related strategies (Special Olympic soccer, etc.). ConclusionThe international attention on the physical fitness for children and adolescents with intellectual disabilities has been increasing in the past decade. Researches focus on the dysfunction of physical fitness for children and adolescents with intellectual disabilities, such as Down syndrome and autism spectrum disorder; in terms of physical structure and function including body composition and executive ability, etc., and in terms of social and participation including physical activity and quality of life, etc.. In addition, physical fitness intervention strategies, such as traditional physical fitness exercise, moderate-to-vigorous physical activity, adaptive physical activity, adaptive sports and special Olympic sports are also research hotspots. Those strategies adhere to the concept of "sports for life" and are closely linked with daily life, in order to help them to improve their physical and mental health level, social participation ability, quality of life and well-being.
