Background::Hepatitis B poses a heavy burden for children in China, however, the national studies on the distributional characteristics and health care costs of children with severe hepatitis B is still lacking. This study aimed to analyze the disease characteristics, health economic effects, and medical cost for children with severe hepatitis B in China.Methods::Based on patient information in the Hospital Quality Monitoring System, cases with severe hepatitis B were divided into four groups according to age, and the etiology and symptoms of each group were quantified. The cost of hospitalization was calculated for cases with different disease processes, and severity of disease. The spatial aggregation of cases and the relationship with health economic factors were analyzed by Moran’s I analysis. Results::The total number of children discharged with hepatitis B from January 2016 to April 2022 was 1603, with an average age of 10.5 years. Liver failure cases accounted for 43.48% (697/1603) of total cases and cirrhosis cases accounted for 11.23% (180/1603). According to the grouping of disease progression, there were 1292 cases without associated complications, and the median hospitalization cost was $818.12. According to the spatial analysis, the aggregation of cases was statistically significant at the prefectural and provincial levels in 2019, 2020, and 2021 (all P <0.05). The number of severe cases was negatively correlated with gross domestic product (Moran’s I <0) and percentage of urban population (Moran’s I <0), and positively correlated with the number of pediatric beds per million population (Moran’s I >0). Conclusion::The number of severe hepatitis B cases is low in areas with high gross domestic product levels and high urban population ratios, and health care costs have been declining over the years.

OBJECTIVE:Percutaneous sacroiliac screw internal fixation has become the main surgical procedure for the treatment of posterior pelvic ring fractures;however,the unassisted closure operation requires high operator experience and repeated fluoroscopy increases the radiation hazard for patients and medical personnel.This article compares the clinical efficacy of robot-assisted versus unassisted percutaneous sacroiliac screw placement for posterior pelvic ring fractures by meta-analysis. METHODS:Computer searches of CNKI,WanFang,VIP,CBM,PubMed,Embase,Cochrane Library and ClinicalTrials.gov were conducted from the time of database inception to December 2022.The literature on the clinical efficacy of robot-assisted versus freehand percutaneous sacroiliac screw placement in the treatment of posterior pelvic ring fractures was collected in and outside China.The data were independently screened and extracted by two investigators according to the inclusion and exclusion criteria,respectively.The quality of randomized controlled trials was evaluated using Cochrane risk assessment criteria.The quality of included cohort studies was assessed using the Newcastle-Ottawa Scale.Meta-analysis was performed using RevMan 5.4 software for inclusion metrics.Outcome metrics included operative time,intraoperative bleeding,fluoroscopy time,fluoroscopy frequency,number of holes drilled,Majeed postoperative function score,the excellent and good rates of Matta fracture reduction,the excellent and good rates of Gras screw position,fracture healing time and complications. RESULTS:(1)A total of 13 publications were included,2 were randomized controlled trials both referring to randomized methods,11 non-randomized controlled studies were evaluated for quality of literature according to the Newcastle-Ottawa Scale,1 scored 8,9 scored 7;and 1 scored 6;the quality of literature was good.A total of 748 patients were included,including 430 in the robot-assisted group and 318 in the freehand group.(2)The results of the meta-analysis showed that the operative time(MD=-28.30,95%CI:-40.20 to-16.40),intraoperative bleeding(MD=-6.36,95%CI:-10.06 to-2.66),intraoperative fluoroscopy time(MD=-12.13,95%CI:-19.54 to-4.72),intraoperative fluoroscopy frequency(MD=-17.39,95%CI:-29.00 to-5.78),number of intraoperative needle drillings(SMD=-9.50,95%CI:-14.27 to-4.73)and the excellent and good rates of Gras screw position(OR=8.65,95%Cl:3.26-22.92)in the robot-assisted group were significantly better than those in the freehand group(P<0.05).(3)In the robot-assisted group,the overall postoperative complication rate was significantly reduced(OR=0.10,95%Cl:0.02-0.48,P<0.05).(4)No significant difference was detected in fracture healing time(MD=-0.08,95%CI:-0.21,0.06),the excellent and good rates of Matta fracture repositioning rate(OR=2.06,95%Cl:0.97-4.39),and Majeed functional score(MD=0.91,95%CI:-0.31-2.13)between both groups(P>0.05). CONCLUSION:Compared with freehand sacroiliac joint nailing,robotic assistance shortens the operative time,reduces intraoperative bleeding,decreases radiation damage to patients and medical staff,improves the excellent and good rate of screw position,and reduces the overall incidence of postoperative complications in patients,but there was no significant improvement in fracture reduction quality,fracture healing time,and postoperative function.In the future,more large-sample,multicenter,and high-quality randomized controlled trials are still needed to verify.

Objective:To investigate the safety and efficacy of laparoscopic simultaneous bilateral adrenalectomy in treating ectopic ACTH syndrome (ACTH)caused by medullary thyroid carcinoma(MTC).Methods:A 56-year-old male patient was admitted after MTC surgery and 7 months of general fatigue. The patient had a history of two open thyroid surgeries for medullary thyroid carcinoma, with previous pathological reports indicating lymph node metastasis in the upper mediastinum and mediastinum, accompanied by weak cytoplasmic expression of ACTH and negative CRH staining. After the operation, the patient developed diabetes, hypertension, and hypokalemia. Upon admission, the patient presented with a blood pressure reading of 200/95 mmHg (1 mmHg = 0.133 kPa), a weight of 61.5 kg, a height of 160 cm, a body mass index (BMI)of 24.02 kg/cm 2, and a waist circumference of 83 cm. Laboratory tests revealed the following: blood potassium level of 2.71 mmol/L, blood calcium level of 1.47 mmol/L, parathyroid hormone level of 6.0 pg/ml, fasting blood glucose level of 10.51 mmol/L, glycated hemoglobin level of 8.2%, blood calcitonin level exceeding 2 000 pg/ml, and blood CEA level of 70.8 μg/L. The plasma ACTH levels at 8∶00, 16∶00, and 24∶00 were 189.0, 125.0, and 65.0 pg/ml, respectively. Serum cortisol levels at 08∶00, 16∶00, and 24∶00 were 429.30, 408.14, and 446.61 μg/L, respectively. The 24-hour urine free cortisol measurement was 1 200 μg, and after the midnight 1mg dexamethasone suppression test at 8∶00, the plasma ACTH level was 183.0 pg/ml, and the serum cortisol level was 538.27 μg/L. The aldosterone level in standing position after 2 hours was 8.2 pg/ml. There were no significant abnormality in catecholamine hormone detection or thyroid function in blood and urine samples. An 18F-FDG-PET/CT examination showed multiple lymph node metastases in the neck, while an abdominal CT scan revealed bilateral adrenal hyperplasia. Enhanced MRI revealed pituitary gland thinning, and lung CT and sputum culture examinations showed scattered multiple lung infections. After a multidisciplinary discussion, the patient was diagnosed with EAS, postoperative MTC metastasis, diabetes, hypertension, hypokalemia, pulmonary infection, mild anemia, liver dysfunction, hypoparathyroidism, and hypocalcemia. The patient were accepted laparoscopic bilateral adrenalectomy via an abdominal approach under general anesthesia. The left adrenal gland was removed first, followed by the right adrenal gland after repositioning. Results:The surgery was successful with a surgical duration of approximately 60 minutes and an intraoperative bleeding volume of about 20 ml. No surgical complications occurred during the perioperative period. Pathological examination confirmed nodular hyperplasia of the adrenal cortex and bilateral adrenal medullary hyperplasia with negative ACTH staining. After a 3-month postoperative follow-up, blood calcitonin levels remained above 2000 pg/ml. The blood ACTH levels at 1 week, 1 month, and 3 months after surgery were 183.0, 220.0, and 731.0 pg/ml, respectively. However, hypertension, diabetes, and hypokalemia rapidly improved. One month after surgery, blood pressure was 100/80 mmHg, fasting blood glucose was 4.4 mmol/L, and blood potassium was 3.87 mmol/L. Pulmonary infection showed improvement, and no adrenal crisis occurred. Glucocorticoid replacement therapy consisted of 20 mg of hydrocortisone tablets in the morning and 10 mg in the afternoon, and thyroid hormone replacement therapy involved daily administration of 100 μg of levothyroxine. Genetic testing revealed heterozygous mutations in the Ret gene. The patient is currently undergoing clinical trial treatment with Ret inhibitors.Conclusions:Based on the data from this case and existing literature reports, laparoscopic simultaneous bilateral adrenalectomy might be safe and effective treatment option for EAS caused by unresectable MTC metastasis. It can correct hypertension, diabetes, and hypokalemia and increase the opportunity for MTC treatment.

Objective:To explore the application of a scenario-based onsite first-aid skills station in objective structured clinical examination (OSCE).Methods:Based on common scenarios and cases in medical practice, an evaluation framework of the OSCE onsite first-aid skills station—containing assessment indicators, exam room setting, examiner training, and assessment process—was designed to evaluate the onsite first-aid competencies of medical graduates of the five-year program for three consecutive years. SPSS 24.0 was used to perform the Kruskal-Wallis test and Pearson correlation analysis to calculate the correlation between course examination scores and OSCE onsite first-aid skills station assessment scores. Excel was used to calculate the difficulty index and discrimination index of test items.Results:The graduates' OSCE onsite first-aid skills station assessment scores were improved year by year, with a mean score of about 80 points. The station assessment items showed a moderate difficulty level (0.7-0.8), a good discrimination level (>0.4), and good internal consistency (Cronbach's α>0.7). The examiners and examinees had a high recognition of the design and effectiveness of this station assessment method. There was a positive correlation between the OSCE scores and corresponding course scores (2016, r=0.245, P=0.001; 2017, r=0.108, P=0.026; 2018, r=0.198, P=0.006). Conclusions:Through scientific scoring and strict examination management, the OSCE scenario-based onsite first-aid skills station can effectively evaluate examinees' injury treatment competencies in different situations, which can provide a reference for course teaching.
