RESUMO
PURPOSE: Study of patients with adolescent idiopathic scoliosis. OBJECTIVE: To examine the correlation between pulmonary arterial pressure and coronal Cobb angle of idiopathic scoliosis. METHODS: A total of 338 patients (82.8 % female) with idiopathic scoliosis (average age 15.6 years; range 14-20 years) were included. Preoperatively, the coronal Cobb angle of curvature and the apex location and direction were determined from radiographic records. Tricuspid regurgitation velocity (TRV) and inferior vena cava diameter were also measured using Doppler echocardiography. Pulmonary arterial systolic pressure (sPAP) was calculated from the TRV according to the modified Bernoulli equation and correlations between sPAP and the features of scoliosis were identified by statistical analysis. RESULTS: Among the 338 patients, there were 305 thoracic curves, 276 (90.5 %) of which were right curves, and 265 thoracolumbar/lumbar curves. sPAP varied from 5.0 to 37.6 mmHg. Pulmonary hypertension could not be excluded in the case of one patient. A mild correlation (Spearman test, correlation coefficient = 0.187, P = 0.001) between sPAP and coronal Cobb angle of the main thoracic (MT) curves was identified. Correlations between sPAP and the degree of other curves were not significant. Patients with sPAP >20 mmHg also had larger thoracic curve angles (mean MT 42.16° vs. 52.45°; U test, P = 0.002). There were no differences in sPAP levels between patients with right and left thoracic curves. CONCLUSIONS: A mild positive correlation was identified between sPAP and the coronal Cobb angle of the MT curves. There was no relationship between sPAP and the direction of the curvature.

Background: Since entering the 21st century, there has been an increasing interest in minimally invasive surgery for spinal diseases, which has led to the continued development of minimally invasive spine surgery (MISS), with major breakthroughs in technology and technical skills. However, in recent years, there is little relevant research using bibliometrics to analyze the field of MISS research. The purpose of this study is to sort out the publication situation and topic trends of articles in the field of MISS research from the perspective of bibliometrics. Methods: The articles and reviews related to MISS from 2000 to 2022 were retrieved and downloaded from the Web of Science Core Collection (WOSCC). Visualization and knowledge mapping were performed using three bibliometric tools, including online bibliometric platform, CiteSpace and VOSviewer software. Curve fitting and correlation analysis were performed using Microsoft Excel software. The global research publication output, contributions of countries, institutions, authors, and journals, average citations per item (ACI), Hirsch index (H-index), research hot keywords, etc., in this field were analyzed. Results: A total of 2384 papers were retrieved, including 2135 original papers and 249 review papers. In the past 22 years, the number of annual publications of MISS research has shown a steady growth trend. China contributed the most papers, and the United States ranked second, but the United States had the highest total citations, and H-index value. The most prolific institutions were Soochow University, Capital Medical University and Wooridul Spine Hospital. In this field, Professors Lee SH, Ahn Y and Yang HL have made significant achievements. However, there is relatively little international collaboration between institutions or researchers. World Neurosurgery is the most published journal on MISS research. According to the keyword co-occurrence analysis, recent keywords mainly focus on researches on minimally invasive modalities, techniques and prognosis, while on the keyword analysis of the ongoing bursts, percutaneous transforaminal endoscopic discectomy, lumbar diskectomy, spinal stenosis, recompression, diskectomy, endoscopic spine surgery, laminectomy, transforaminal lumbar interbody fusion, etc., will likely continue to be a research hotspot in the near future. Conclusion: Looking at the temporal trend in the number of publications per year, the number of publications for the MISS study will increase in the near future. China has the highest number of publications, but the US has the highest quality publications. International cooperation needs to be further strengthened. Our findings can provide useful information for the academic community and identify possible research fronts and hotspots in the coming years.
RESUMO
Objectives: To investigate the safety and feasibility of gasless axillary parathyroid surgery in the treatment of primary hyperparathyroidism. Methods: A total of 12 patients who received gasless axillary parathyroidectomy (endoscope group) and 14 patients who received traditional open parathyroidectomy (open group) from January 2019 to April 2022 were screened and included. The differences in baseline characteristics, surgical efficiency, incidence rate of complications, changes in biochemical indicators, and incision satisfaction between the two groups were analyzed and compared. Results: The proportion of young patients was higher in the endoscopic group than in the open group, and the difference was statistically significant [(41.33 ± 13.65) years vs. (58.00 ± 9.44) years, P < 0.01]. The differences in operation time, intra-operative blood loss, post-operative drainage volume, hospital stay, and surgical efficiency between the two groups yielded no statistical significance (P > 0.05). Patients in the open group had more significant neck pain 3 days after surgery (P = 0.046), but the degree of pain 3 months after surgery was the same in the 2 groups (P = 0.432). Evaluation of post-operative mature stage scar and incision satisfaction regarding aesthetics in the endoscope group were significantly superior to that in the open group [(1.92 ± 0.92) points vs. (0.92 ± 1.00) points, P = 0.017 and (1.57 ± 0.51) points vs. (1.00 ± 0.013) points, P = 0.013, respectively]. No statistical significance was found in terms of incidence rate of post-operative fever (P > 0.05). No temporary recurrent laryngeal nerve injury, post-operative bleeding, incision hematoma infection, or other complications were observed. Comparing the two groups, the extent of the level decrease of PTH was similar to that of serum calcium and phosphorus (P < 0.05), where most patients experienced transient hypocalcemia after operation yielding no significant difference in incidence (P = 0.225). During a follow-up period of 3 to 36 months, a total of 1 patient in the open group experienced recurrence at 10 months after surgery and was treated non-surgically. Conclusion: Gasless axillary approach to parathyroid surgery for primary hyperparathyroidism possesses good safety and patient satisfaction in terms of aesthetics.
