With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

OBJECTIVE: To explore the methods, fixation points, and effectiveness of staged therapy using external fixation frame in treatment of infectious nonunion near knee joint. METHODS: A retrospective analysis was conducted on the clinical data of 60 patients with infectious nonunion near knee joint, who underwent staged therapy using external fixation frame between June 2021 and June 2024 and were followed up. There were 48 males and 12 females with an average age of 47.9 years (range, 16-70 years). The disease duration ranged from 9 months to 20 years, with a median of 14 months. Among them, 21 cases of infectious nonunion located in the distal femur, 36 cases in the proximal tibia, and 3 cases in the patella; 12 cases exhibited segmental bone defects (≥4 cm), while 48 cases presented with localized bone defects (<4 cm). Osteomyelitis was classified using the Cierny-Mader system, with 3 cases classified as type Ⅰ, 6 cases as type Ⅱ, 35 cases as type Ⅲ, and 16 cases as type Ⅳ. Preoperative C-reactive protein levels ranged from 15.1 to 55.8 mg/L (mean, 36.4 mg/L). The erythrocyte sedimentation rate was 35-80 mm/1 h (mean, 56.9 mm/1 h). The Hospital for Special Surgery (HSS) score for knee joint was 69.3±17.7 and the range of motion was (70.61±40.60)°. After debridement and placement of antibiotic carriers at the first-stage operation, unilateral orbital frames ( n=14), combined frames ( n=27), or Ilizarov frames ( n=19) were used for cross joint fixation ( n=9) or joint preservation fixation ( n=51). After 6-8 weeks of infection control, the bone grafting or bone transport was performed at the second-stage operation based on the type of bone defect, with internal fixation employed as an adjunct if necessary. After operation, the infection control and fracture healing were observed and the bone healing time was recorded. The knee joint function was assessed using the HSS score, and the knee joint range of motion was measured as well as the angle of motion loss. Patients were grouped according to the site of nonunion, type of external fixation frame, and fixation method. The bone healing time, change value of HSS score, and knee joint range of motion loss (difference between pre- and post-operation) were compared between groups. RESULTS: All infection markers returned to the normal range within 6 weeks after the first-stage operation. All patients were followed up 12-48 months (mean, 22.0 months) after the second-stage operation. There were 5 cases of needle tract infection during the external fixation period, and 3 cases of infection recurrence after the second-stage operation, all of which were cured after symptomatic treatment. The bone healing time was 6-18 months (mean, 11.0 months). At last follow-up, the HSS score was 88.5±7.9 and the range of motion was (61.84±40.59)°, with significant differences compared to preoperative values ( P<0.05); the knee joint range of motion loss was (8.77±11.07)°. The bone healing time was significantly longer in the distal femur group than in the proximal tibia group ( P<0.05), and in the unilateral orbital frames group than in the Ilizarov frames group and the combined frames group ( P<0.05). The angle of motion loss was significantly larger in the Ilizarov frames group than in the unilateral orbital frames group and the combined frames group ( P<0.05). The change value of HSS score was significantly higher in the cross joint fixation group than in the joint preservation fixation group ( P<0.05). CONCLUSION During the first-stage operation, debridement is performed and antibiotic carriers are placed to control infection. External fixation frames are then precisely positioned based on the distance between the lesion and the joint surface, avoiding the infected wound while ensuring mechanical balance. During the second-stage operation, bone grafting options are selected according to the extent of bone defects to enhance the bone union. Postoperative early functional exercises of the knee joint are permitted to improve joint function.

OBJECTIVE: To explore the effectiveness of primary interventional revascularization combined with secondary perforator composite flap in the treatment of peripheral arterial disease (PAD) accompanied by soft tissue defects around the ankle. METHODS: Between January 2022 and January 2025, 12 patients with PAD and soft tissue defects around the ankle were admitted. Among them, there were 9 males and 3 females; their ages ranged from 52 to 82 years, with an average of 68.9 years. The causes of injury included 4 cases of traffic accident, 5 cases of falls, 1 case of falling from height, 1 case of foreign body puncture injury, and 1 case of electric shock injury. The infection duration ranged from 1 month to 35 years, with a median duration of 3.5 months. The wound size ranged from 5.5 cm×3.0 cm to 15.0 cm×9.0 cm. The ankle-brachial index (ABI) was 0.32±0.12. The visual analogue scale (VAS) score for pain was 3.3±0.5. Preoperative vascular stenosis assessment was performed in all patients, with primary intervention to dredge large and medium-sized arteries, followed by secondary repair of the wound using a perforator composite flap. The flap size ranged from 6.5 cm×4.0 cm to 16.0 cm×10.0 cm. The donor sites were sutured directly or repaired with skin grafts. After two stages of treatment, the effectiveness was evaluated by measuring ABI, observing flap survival and wound healing, assessing VAS scores, and American Orthopedic Foot and Ankle Society (AOFAS) scores. RESULTS: All 12 cases completed two stages of treatment; all patients were followed up after the second-stage treatment, with a follow-up period ranging from 7 to 28 months, with an average of 16.8 months. After the first-stage treatment, the skin temperature around the ankle was significantly higher than that before treatment, and the ABI increased to 0.71±0.07, with a significant difference ( t=9.918, P<0.001). After the second-stage treatment, the blisters on the distal end of the skin flap occurred in 3 cases. The flaps survived and the wounds healed, with a healing time ranging from 10 to 14 days (mean, 11.8 days). The incisions at the donor site healed by first intention, and the skin grafts survived. The VAS score was 0.5±0.5 at 3 weeks, which was significantly lower than that before treatment ( t=13.675, P<0.001). No infection recurrence occurred during follow-up. At 6 months after the second-stage treatment, the AOFAS score of the ankle joint ranged from 92 to 97, with an average of 94.7, all reaching excellent. CONCLUSION Interventional revascularization combined with perforator composite flap for staged treatment of PAD with ankle soft tissue defects can obtain good effectiveness, by unclogging the main blood vessels, improving lower limb blood supply, and improving the survival rate of the skin flap.

Neoplasms characterized by the expression of markers of neuroendocrine differentiation in neoplastic cells are defined as neuroendocrine neoplasms. A case of neuroendocrine carcinomas (NECs) with a small amount of papillary adenocarcinoma and significantly vacuolar nucleus at the esophagogastric junction was reported in this article. A 77-year-old male had dysphagia for one week. Endoscopy revealed early-stage esophagogastric junction carcinoma, and biopsy was diagnosed as poorly differentiated carcinoma. Endoscopic submucosal dissection was performed. Histologically, the papillary adenocarcinoma progresses from typically branching papillary structures (well-differentiated) to hyperplasia of the lining epithelium of the papilla to form a cribriform structure (moderately differentiated), to solid area lacking papillary structures (poorly differentiated). There was a continuous process, and during this process, the vacuoles in the nuclei of tumor cells showed progressive changes from mild to obvious and finally to significant vacuoles. The tumor was mainly composed of solid areas (about 95%), with single cell, large cell, round or oval to irregular nuclei, and significantly vacuolar nuclei, nuclei with larger vacuoles appeared in a loop, a few thin weakly basophilic or weakly eosinophilic fine particles could be seen in the vacuoles, and the vacuoles had rough edges. The nucleus chromatin at the outer edge of the vacuoles was fine particles, and mitosis was common (20-30/mm²), atypical mitosis could be seen, and nucleoli could be seen easily, the cytoplasm was weakly eosinophilic, and the boundaries of cells were unclear. The cells were arranged in a nested, trabecular, or diffuse sheet shape, with some arranged in a glandular tube shape. Tumor thrombus was found in the vein of submucosa; the interstitial tissue rich in capillaries within the tumor was accompanied by a large number of neutrophil infiltration. Immunohistochemical staining showed that the solid area of the tumor was positive for synaptophysin (Syn) and chromogranin A (CgA), while papillary adenocarcinoma was negative. Mucin 5AC (MUC5AC) was diffusely positive in papillary adenocarcinoma, while the proportion of positive cells in the solid area of the tumor was about 10% to 15%. In a word, this case showed the extreme situation of the vacuolar nuclear characteristics of NECs, extremely rare, in a sense, this case expanded the boundary of the morphological spectrum of NECs. Understanding the extreme vacuolar features of this nucleus is helpful to make a correct pathological diagnosis.

Objective To investigate the factors influencing the efficacy of intravesical Bacille Calmette-Guérin(BCG)instillation after transurethral resection of bladder tumor(TURBT)in patients with intermediate-and high-risk non-muscle invasive bladder cancer(NMIBC),and to construct a prediction model for recurrence after BCG treatment.Methods A retrospective cohort study was conducted on the subjected patients diagnosed with intermediate-and high-risk NMIBC undergoing TURBT followed by standard BCG instillation.The 110 patients treated in Department of Urology of Army Medical Center of PLA from January 2018 to December 2023 were assigned into a training set,while the 52 patients treated at Department of Urology of General Hospital of Central Theater Command from January 2015 to December 2020 were into an external validation set.A total of 17 variables were included and analyzed.Univariate and multivariate Cox regression analyses were performed to identify factors associated with recurrence after BCG instillation,and nomograms were plotted to predict 1-year,3-year,and 5-year recurrence-free survival(RFS).Calibration curve,decision curve analysis(DCA),and receiver operating characteristic(ROC)curve analysis were conducted for internal and external validation to evaluate the predictive performance and clinical utility of the model.Results In the training set,26 patients(23.64%)experienced recurrence during the follow-up period,with a median RFS of 32.00(18.00～50.50)months.Univariate Cox regression analysis suggested that platelet count,eosinophil to lymphocyte ratio(ELR),neutrophil to lymphocyte ratio(NLR),platelet to lymphocyte ratio(PLR),systemic immune inflammation(SII)index,and neutrophil-monocyte to lymphocyte ratio(NMLR),pathological T1 stage(pT1)tumor and hemoglobin,albumin,lymphocyte,and platelet(HALP)score were potential factors influencing recurrence after BCG instillation.Multivariate Cox regression analysis identified high HALP score(HR=0.185,95%CI:0.046～0.736,P=0.017)as an independent protective factor,while high ELR(HR=3.599,95%CI:1.505～8.608,P=0.004)and pT1 stage(HR=3.240,95%CI:1.191～8.818,P=0.021)were independent risk factors for recurrence.Based on this,a nomogram prediction model was constructed.The calibration curves demonstrated good agreement between predicted and actual 1-,3-,and 5-year recurrence risks.Decision curve analysis indicated clinical utility across a wide threshold probability range.In the training set,the model showed strong predictive performance for 1-(AUC=0.842),3-(AUC=0.847),and 5-year(AUC=0.887)recurrence risks,which was further validated in the external cohort.Conclusion Higher HALP score prior to BCG instillation therapy is a protective factor against tumor recurrence,while higher ELR and pT1 stage are risk factors.Our nomogram prediction model based on HALP score,ELR and pathological T stage,can identify individuals at high risk of recurrence after BCG instillation therapy.

Objective To investigate the appropriate venous access for obese patients undergoing metabolic and bariatric surgery by comparing the clinical outcomes of different lengths of peripheral intravenous catheters.Methods Inpatients who underwent bariatric surgery in a tertiary hospital in Zhejiang from August 2022 to December 2022 were selected as the study population using a fixed-point continuous convenience sampling method.A stratified block randomisation method was used to divide the group into an experimental group 1(mini-midline catheters),an experimental group 2(midline catheters)and a control group(short peripheral intravenous catheters,Short PIVCs).The incidence of catheter-related complications,the rate of extubation due to complications,the duration of catheter retention,the time to first catheter-related complication were compared in the 3 groups.Results A total of 186 patients were included,with 62 patients in each group.The overall incidence of catheter-related complications in experimental group 1,experimental group 2,and control group were 25.81％,8.06％,and 58.06％.The extubation rates due to complications were 19.35％,4.84％,and 41.94％,and the duration of catheter retention was 7.00(6.00,7.00)d,7.00(6.00,7.00)d,6.00(3.00,6.25)d.The differences were statistically different(P＜0.05)when comparing the 3 groups.Among them,the differences in the overall incidence of catheter-related complications and the rate of extubation due to complications were statistically significant when comparing experimental group 1 with the control group,experimental group 2 with the control group,and experimental group 1 with experimental group 2(P＜0.017);the duration of catheter retention in both experimental group 1 and experimental group 2 were higher than it in the control group,and the differences were statistically different(P＜0.017).Conclusion The complication rate of mini-midline catheters and midline catheters is lower than that of short ones,and the indwelling time is consistent with the perioperative period of metabolic and bariatric surgery,which is suitable for use in patients undergoing metabolic and bariatric surgery.

Postoperative pain, a common problem in perioperative management, has negative impact on patients' experience and functional recovery. The development of postoperative pain is not only related to direct surgical trauma, but also a series of preventable perioperative risk factors, among which perioperative sleep quality should not be neglected. In recent years, more and more researches have indicated that poor perioperative sleep quality is a risk factor for both acute and chronic postoperative pain, and some researches have even pointed out that sleep quality can directly influence patients' pain threshold. Therefore, this review aims to summarize current research progress on the influence of perioperative sleep quality on postoperative pain, hoping to provide reference for improving the perioperative pain management for patients.

Objective:To evaluate the impact of orthopedic robotic assistance and conventional freehand methods on surgical strategies, the safety of pedicle screw placement, and clinical efficacy in patients with upper cervical spine diseases.Methods:From January 2017 to March 2023, a total of 63 cases with upper cervical spine disease, were divided into two groups based on the screw placement technique: the robot-assisted pedicle screw placement (RA) group (41 cases) and the conventional freehand pedicle screw placement (CF) group (22 cases), were retrospectively included. These patients in the RA and CF groups underwent two types of posterior cervical surgery, including occipitocervical fusion (9 cases and 8 cases) and fixation and fusion of atlantoaxial and distal vertebrae (32 cases and 14 cases). The outcome parameters, including the disease course, surgical time, intraoperative blood loss, fluoroscopy frequency, radiation dose, hospital stay, treatment costs, complications, the rate of the pedicle screw placement, accuracy of upper cervical pedicle screw placement, and the risk factors that possibly affected the accuracy were recorded and analyzed. Postoperative follow-up was conducted for at least 6 months, and the efficacy of patients was assessed using imaging parameters, ASIS classification, VAS, and JOA scores.Results:Both groups had no screw-related complications and no spinal cord or vertebral artery injuries. In the RA group, the pedicle screw placement rates for the patients with occipitocervical fusion, and fixation and fusion of atlantoaxial and distal vertebrae were 100% (48/48) and 89.6% (138/154), respectively, far exceeding the placement rate in the CF group 42.9% (18/42) and 78.3% (54/69) (χ 2=37.403, P<0.001; χ 2=5.128, P=0.024). The fluoroscopic exposure dose and operation time of the two types of surgical patients in the RA group were both higher than those in the CF group ( P<0.05). Compared with the CF group, the accuracy of C 1 screws in the RA group increased from 42% (11/26) to 80% (51/64), with statistical significance (χ 2=13.342, P=0.004); while the accuracy of C 2 screws improved from 77% (33/43) to 88% (63/72) with no statistical difference (χ 2=2.863, P=0.413). Non-parametric correlation analysis found a significant correlation between the accuracy of C 1 and C 2 pedicle screw placement and the order of guide wire insertion in the RA group ( r=0.580, P<0.001; r=0.369, P=0.001). Postoperatively, both groups showed significant differences in cervicomedullary angle (CMA), Chamberlain angle (CL), McGregor angle, Boogard angle, Bull angle, clivus-canal angle (CCA), occipitocervical (C 0-C 2) angle, posterior occipitocervical angle (POCA), C 2-C 7 angle, and anterior atlantodental interval (ADI) ( P<0.05). The ASIA classification improved to varying degrees for both groups postoperatively, but there were no statistically significant differences between preoperative, postoperative, and last follow-up evaluations. VAS and JOA scores significantly improved for both groups postoperatively and at the last follow-up ( P<0.05). Conclusion:Both orthopedic robotic-assisted and conventional freehand pedicle screw placement techniques achieved satisfactory therapeutic effects in the treatment of upper cervical spine diseases. The orthopedic robot can effectively ensure the accuracy of upper cervical pedicle screw placement, the increase placement rate of pedicle screws in the upper cervical spine, and reduce fluoroscopy exposure. However, it is necessary to avoid the vertebral displacement caused by the priority insertion of the guide needle, which may affect the accuracy of subsequent planning.

Objective:To summarize the clinical and prognostic features of children with opsoclonus-myoclonus-ataxia syndrome (OMAS).Methods:A total of 46 patients who met the diagnostic criteria of OMAS in the Department of Neurology, Beijing Children′s Hospital from June 2015 to June 2023 were retrospectively analyzed. Centralized online consultations or telephone visits were conducted between June and August 2023. The data of the children during hospitalization and follow-up were collected, including clinical manifestations, assistant examination, treatment and prognosis. According to the presence or absence of tumor, the patients were divided into two groups. The chi-square test or Mann-Whitney U test was used to compare the differences between the two groups. Univariate Logistic regression was used to analyze the factors related to OMAS recurrence and prognosis. Results:There were 46 patients, with 25 males and the onset age of 1.5 (1.2, 2.4) years. Twenty-six (57%) patients were diagnosed with neuroblastoma during the course of the disease, and no patients were categorized into the high-risk group. A total of 36 patients (78%) were followed up for≥6 months, and all of them were treated with first-line therapy with glucocorticoids, gammaglobulin and (or) adrenocorticotrophic hormone. Among the 36 patients, 9 patients (25%) were treated with second-line therapy for ≥3 months, including rituximab or cyclophosphamide, and 17 patients (47%) received chemotherapy related to neuroblastoma. At the follow-up time of 4.2 (2.2, 5.5) years, 10 patients (28%) had relapsed of OMAS. The Mitchell and Pike OMS rating scale score at the final follow-up was 0.5 (0, 2.0). Seven patients (19%) were mildly cognitively behind their peers and 6 patients (17%) were severely behind. Only 1 patient had tumor recurrence during follow-up. The history of vaccination or infection before onset was more common in the non-tumor group than in the tumor group (55%(11/20) vs. 23%(6/26), χ2=4.95, P=0.026). Myoclonus occurred more frequently in the non-tumor group (40%(8/20) vs. 4%(1/26), χ2=7.23, P=0.007) as the onset symptom. Univariate Logistic regression analysis showed that the tumor group had less recurrence ( OR=0.19 (0.04-0.93), P=0.041). The use of second-line therapy or chemotherapy within 6 months of the disease course had a better prognosis ( OR=11.64 (1.27-106.72), P=0.030). Conclusions:OMAS in children mostly starts in early childhood, and about half are combined with neuroblastoma. Neuroblastoma in combination with OMAS usually has a low risk classification and good prognosis. When comparing patients with OMAS with and without tumors, the latter have a more common infection or vaccination triggers, and myoclonus, as the onset symptom, is more common. Early addition of second-line therapy is associated with better prognosis in OMAS.

Objective To investigate the value of 18F labeled prostate-specific membrane antigen(18F-PSMA)-1007 developing agent PET/CT(18F-PSMA-1007PET/CT)examination in the diagnostic evaluation and therapeutic decision of the newly diagnosed prostate cancer(PCa)and follow up after radical prostatecto-my(RP).Methods This study adopted the retrospective observational study method.A total of 68 patients receiving 18 F-PSMA-1007 PET/CT examination in this hospital from September 2022 to October 2023 were analyzed,including 36 cases of newly diagnosed PCa and 32 cases of biochemistry follow up failure after RP.A total of 30 items of clinical data were collected,including 8 items of basic clinical characteristics,7 items of pa-thology-related characteristics and 15 items of imaging characteristics.The patients clinical characteristics in the newly diagnosed PCa and biochemical failure after RP conducted the descriptive analysis.The Fisher exact probability method was used to analyze the differentiation of the SUVmax of primary lesions in different clini-cal subgroups[different tPSA levels at diagnosis,different mi-T stages,different Gleason scores at postopera-tive pathological puncture and different pathological types]in the newly diagnosed PCa group and the differ-entiation of recurrent lesion detection rates in different clinical subgroups(different tPSA in 18F-PSMA-1007 PET/CT examination,different pathological T stages,different lymph node invasion and different pathological Gleason scores in the biochemical failure after RP group.The Spearman correlation was adopted to test and analyze the correlation between the imaging features of positive lesions and tPSA.Results In the newly diag-nosed PCa group,there were 1 case of prostatic hyperplasia and 35 cases of PCa.SUVmax had no statistical differences among the primary lesions with different tPSA levels(P=0.81),different mi-T stages(P=0.70),different puncture Glleasonscores(P=0.20)and different pathological types(P=0.71).Moreover the tPSA value at diagnosis was positively correlated with the number of metastatic lesions(r=0.410,P=0.01).The clinical treatment decisions in 11 cases(31.43％)were changed according to the examination re-sults.In 9 cases of RP combined with lymph node dissection,the accuracy rate and concordance rate of 18F-PS-MA-1007 PET/CT and MRI in the lymph node detection rate all were 100％.I n the biochemical failure after RP group,the overall recurrent lesion detection rate was 71.88％(23/32),the operative area in situ recurrence(11 cases,34.38％)and bone metastasis(11 cases,34.38％)were most common.The differences of 18F-PS-MA-1007 PET/CT recurrent lesions detection rates had no statistical differences among the patients with dif-ferent tPSA levels(P=0.08),different pathological T stages(P=0.10),different postoperative pathological lymph node invasions(P=0.68)and different pathologic Gleason score in the 18F-PSMA-1007 PET/CT ex-amination.In the 18 F-PSMA-1007 PET/CT examination in the biochemical failure after RP,the tPSA value in the recurrent lesion was positively correlated with the number of recurrent lesions(r=0.48,P=0.01),SUVmax value in the recurrent lesion(r=0.46,P=0.01)and the SUVmean value(r=0.38,P=0.03).The clinical treatment decision in 18 cases(56.25％)was changed according to the examination results.Conclusion 18 F-PSMA-1007 PET/CT has good diagnostic value and efficiency for primary lesion and metastasis lesion of new-ly diagnosed PCa and recurrent foci of biochemical failure after RP.
