ABSTRACT

Objective: The aim of this paper is to compare the refractive correction effects of rigid gas permeable contact lenses (RGPCL) and spectacle correction in children with aphakia after congenital cataract surgery. Methods: This was a prospective non-randomized controlled trial. Children with aphakic eyes after congenital cataract surgery, who underwent vision correction in the Strabismus and Pediatric Ophthalmology Clinic of Beijing Tongren Hospital affiliated with Capital Medical University from April 2012 to November 2019, were continuously collected. Those who voluntarily chose to wear RGPCL for refractive correction were included in the experimental group. Patients with monocular disease were in trial group 1, and patients with binocular disease were in trial group 2. Patients who chose to wear frame glasses for refractive correction were included in the control group. Patients with monocular disease were in control group 1, and patients with binocular disease were in control group 2. Regional origin, medical history, and family information were collected at the first diagnosis. During the follow-up, adverse reactions occurring during the process of wearing glasses were recorded. The Teller acuity card was used for visual examination to obtain the best-corrected visual acuity and convert it into the logarithm of the minimum resolution angle. The degree of nystagmus was determined according to the amplitude and frequency of nystagmus. Treatment cost, treatment compliance, and the reasons for adopting or not adopting RGPCL were analyzed through a questionnaire completed by the parents of children with RGPCL. Results: A total of 203 children (344 eyes) who underwent congenital cataract surgery were included, including 124 males (210 eyes) and 79 females (134 eyes). The age range was 3 to 36 months. There were 28 cases in the experimental group, including 19 cases in trial group 1 and 9 cases in trial group 2. There were 175 cases in the control group, including 43 cases in control group 1 and 132 cases in control group 2. Except for 6 months of age, the visual acuity of the experimental group was better than that of the control group, and the differences were statistically significant (P<0.05). The visual acuity of children in trial group 1 was better than that of children in control group 1 at the same age. Among them, at 12 months of age [1.54 (1.27, 1.97), 1.84 (0.97, 2.12)], 18 months of age [1.27 (0.97, 1.84), 1.84 (0.97, 2.12)], 24 months of age [1.54 (1.27, 1.84), 1.84 (0.97, 2.12)], and 30 months old [0.97 (0.66, 1.27), 1.54 (0.66, 2.12)], the difference was statistically significant (P<0.001). The visual acuity of children in trial group 2 was better than that in control group 2 at the same age. Among them, at 18 months old [1.27 (0.97, 1.54), 1.27 (0.66, 2.12)], 24 months old [0.97 (0.66, 1.27), 1.27 (0.66, 2.12)], and 30 months old [1.27 (0.66, 2.12)], the difference was statistically significant (P<0.05). The remission rate of nystagmus in the experimental group was 8/9 (8 cases), the remission rate of nystagmus in the control group was 34.40% (32 cases), and the exacerbation rate was 29.03% (27 cases). The average annual cost of the experimental group was 25 125 yuan, and that of the control group was 2 511 yuan. Conclusions: RGPCL is a well-tolerated, safe, and effective treatment for infants and young children. The visual acuity and degree of nystagmus were significantly improved in children who wore RGPCL for aphakia refractive correction after congenital cataract surgery compared with spectacle correction.

ABSTRACT

Objective: To investigate the influence of corneal e-value on the effectiveness of orthokeratology in controlling myopia in children and adolescents. Methods: A retrospective cohort study was conducted, involving the data from 1 563 myopic patients (1 563 eyes) who underwent orthokeratology at the Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine from June 2015 to August 2021 and adhered to lens wear for at least 2 years. The cohort consisted of 737 males and 826 females with an average age of (10.84±2.13) years. Based on corneal e-value parameters obtained from corneal topography, patients were categorized into a low e-value group (n=425) and a high e-value group (n=1 138). Data on gender, age, parental myopia history, and baseline measures such as spherical equivalent (SE), axial length, and corneal e-value were collected. Differences in axial length change and corneal fluorescein staining rates were compared between the two groups at 1 and 2 years after the start of lens wear. A generalized linear mixed model was established with axial length change as the dependent variable to analyze the correlation between axial length change and baseline corneal e-value. Results: The initial age of the 1 563 myopic patients was (10.84±2.13) years, with a baseline SE of (-3.05±1.30) D. After 1 year of lens wear, the axial length change was (0.20±0.19) mm in the low e-value group and (0.24±0.20) mm in the high e-value group. After 2 years, the changes were (0.38±0.25) mm and (0.43±0.27) mm, respectively, with statistically significant differences (all P<0.05). The incidence of corneal staining after 1 year of lens wear was 9.2% (39/425) in the low e-value group and 14.1% (160/1 138) in the high e-value group. After 2 years, the rates were 15.8% (67/425) and 21.8% (248/1 138), respectively, with statistically significant differences (all P<0.05). After adjusting for parental myopia history, age, SE, and baseline axial length, the baseline corneal e-value was positively correlated with axial length change at 1 and 2 years after lens wear (all P<0.05). Conclusions: Corneal e-value is an independent factor influencing the effectiveness of orthokeratology in controlling myopia. A smaller corneal e-value is associated with slower axial length growth after orthokeratology, indicating better control of myopia in treated eyes.

ABSTRACT

The clinical data of 23 patients undergoing real-time echocardiography-guided infusion port implantation in the Breast Center of Tsinghua Changgung Hospital in Beijing from January to July 2021 were analyzed. The length of catheter insertion L1 was initially estimated using surface measurement method in all patients. Intraoperatively, transthoracic echocardiography was applied using the parasternal four-chamber view to visualize the catheter image within the right atrium, and the length of catheter insertion L2 was recorded under the guidance of echocardiography. Postoperatively, chest radiographs were taken in the upright position to observe the position of the catheter tip. According to chest CT scans, the ideal length (L) for catheter tip placement was calculated when it was located at the junction of superior vena cava and right atrium. Bland-Altman scatter plot analysis and linear regression fitting test were used on L1 and L2 respectively with L to evaluate the consistency. A total of 23 patients were included in this study, among which one case of left breast cancer patient undergoing breast-conserving surgery had difficulty in identifying the catheter tip position due to residual pleural effusion obscuring the imaging of the cardiac apex four-chamber view. In 22 patients, the results of intraoperative ultrasound imaging were good, including 1 case of catheter ectopic to azygos vein, and 21 cases of right atrial catheter could be detected by ultrasound. Statistical analysis showed that there was a good consistency between L1 and L, L2 and L, and the difference between them was d=0.28 cm (95%CI:-1.76-2.31 cm) and d=0.20 cm(95%CI:-0.84-1.23 cm), respectively, with no statistical significance (P>0.05). In the linear regression model, L2 and L had a higher fit than L1, and the difference was statistically significant (R²=0.954, P<0.001). This study found that real-time echocardiographic localization technique can be applied in adult port surgery to replace X-ray-guided real-time catheter tip detection and adjustment to the optimal position.

ABSTRACT

Objective: To study the effect of hepatitis B virus (HBV) infection on the occurrence of liver damage, HBV reactivation (HBVr) and the influence of HBVr on the prognosis of patients with advanced hepatocellular carcinoma (HCC) receiving systemic therapy. Methods: The clinical data of 403 patients with HBV-related HCC at the Department of Infectious Diseases, The Third Affiliated Hospital of Sun Yat-Sen University et al, from July 2018 to December 2020 were collected. The incidence of liver damage and HBVr during systematic therapy, and the influence of HBVr on survival prognosis were analyzed. Results: Of the 403 patients, 89.1% were male (n=359), with a median age of 51 years (51.5±12.1). Before propensity score matching (PSM), the proportion of patients with cirrhosis, TNM and advanced BCLC stage was higher in high HBV-DNA (baseline HBV-DNA>1000 U/ml, n=147) group comparing with the low HBV-DNA (baseline HBV DNA≤1000 u/ml, n=256) group (P<0.05). There was no significant difference in baseline indexes between the two groups after PSM. In 290 patients after PSM, there was no significant difference in the incidence of liver damage and HBVr between high HBV-DNA group and low HBV-DNA group (P>0.05). Survival analysis was performed on 169 patients with survival data, the median overall survival (OS) was found to be 11.49 months (95%CI: 7.77-12.89) and 16.65 months (95%CI: 10.54-21.99, P=0.008) in the high and low HBV-DNA groups, respectively. And median progression-free survival (PFS) was 7.41 months (95%CI: 5.06-8.67) and 10.55 months (95%CI: 6.72-13.54, P=0.038), respectively, with a statistically significant difference. There were no differences in overall survival (OS) and progression-free survival (PFS) between patients with and without HBVr and those with or without liver damage (P>0.05). Conclusions: HBV-DNA levels above 1 000 U/ml before systemic therapy do not increase the risk of liver damage or HBVr during systemic therapy in patients with HBV-related hepatocellular carcinoma, and such patients can safely receive systemic therapy.

ABSTRACT

Objective: To explore the efficacy and effective node of short-term personalized vestibular rehabilitation (ST-PVR) in treating acute unilateral vestibulopathy (AUVP). Methods: A randomized controlled trial was carried out. The AUVP patients who were admitted to the First Affiliated Hospital of Zhengzhou University from July 2022 to March 2023 were selected and randomized to the vestibular rehabilitation (VR) group and control group via computer-generated randomization. Standard care was the medical treatment with betahistine and prednisolone. Meanwhile, the VR group received ST-PVR. All the patients completed the baseline assessment and underwent follow-up assessments at 1 month and 3 months after the treatment. The assessments were consisted of spontaneous nystagmus (NYS), Romberg test (ROM), head thrust test (HTT), visual analogue scale (VAS) for vertigo, dizziness handicap inventory scale (DHI), activities-specific balance confidence scale (ABC), caloric test using video-electronystagmograph (VNG), and video-head impulse test (vHIT). The measurement data that did not conform to normal distribution were represented by M (Q₁, Q₃). Generalized estimating equation (GEE) was used to analyze the influence of the ST-PVR on the values of these clinical indicators and the VR grading score. The values of clinical indicators and the VR grading score were compared between the two groups at each follow-up point. Results: Seventy-one AUVP patients were included, with 35 cases in the VR group [14 males and 21 females, aged 51 (33, 55) years] and 36 cases in control group [17 males and 19 females, aged 46 (34, 59) years]. There were statistically significant differences in the impact of ST-PVR on the values of clinical indicators between the two groups (ABC: β=10.89, P<0.001; VAS: β=-1.64, P<0.001; DHI: β=-8.70, P<0.001; NYS: β=26.73, P<0.001; vHIT: β=1.41, P=0.047; the VR grading score: β=1.03, P=0.045). The assessments of the VR group in the positive rate of NYS [14.3% (5/35) vs 50.0% (18/36), P<0.001], ROM [48.6% (17/35) vs 55.6% (20/36), P<0.001], directional preponderance (DP) [34.3% (12/35) vs 75.0% (27/36), P<0.001] and DHI [26 (22, 32) vs 36 (30, 60), P=0.001] were significantly lower than that of the control group at 1 month after the treatment. The results showed a statistically significant difference in ABC [88 (80, 90) vs 76 (61, 88), P<0.001], VAS [2 (1, 3) vs 3 (2, 5), P<0.001] at 3-months after the treatment. The VR grading score of the VR group was improved significantly than those of the control group at 1 month after treatment [21 (17, 21) vs 16 (13, 20), P=0.001]. Conclusion: ST-PVR could improve the results of clinical indicators and VR grading score of the AUVP patients effectively after 1 month of the systematical treatment, and alleviate the symptoms and signs of dizziness in the acute phase as early as possible.

ABSTRACT

Objective: To compare the clinical efficacy of personalized vestibular rehabilitation and otolith reposition in treating atypical benign paroxysmal positional vertigo (BPPV). Methods: A randomized controlled trial was carried out. Fifty patients diagnosed with atypical BPPV in the Vertigo Clinic of the First Affiliated Hospital of Shandong First Medical University from October 2022 to September 2023 were recruited and randomly divided into manual reduction group (25 cases) and vestibular rehabilitation group (25 cases) according to the random number table. All patients were given flunarizine. Patients in the manual reduction group were treated by Epley maneuver and (or) Barbecue maneuver, while the vestibular rehabilitation group was given personalized vestibular rehabilitation therapy. After two weeks’ treatment, the clinical symptoms (positional vertigo/nystagmus) and total dizziness handicap inventory (DHI) score, DHI physical (DHI-P), DHI emotional (DHI-E), and DHI functional (DHI-F) of the two groups were evaluated and compared. Results: A total of 50 patients diagnosed with atypical BPPV were included, including 23 males and 27 females, with an average age of (48.8±14.5) years. There was no statistically significant difference between the two groups in age, gender, disease severity, Romberg, position test abnormality ratio (Dix-hallpike/Roll test), temperature test, and video head impulse test baseline test results (all P>0.05). After 2 weeks of treatment, the effective rates of the treatment in the manual reduction and vestibular rehabilitation groups were 56.0% (14/25) and 88.0% (22/25), respectively, with a statistically significant difference (P=0.025). The total DHI score, DHI-P, DHI-E, and DHI-F scores in both groups were significantly decreased after treatment (all P<0.001). Compared with the manual reduction group, the total DHI score (23.2±2.7 vs 36.4±15.7, P=0.002), DHI-P (10.2±4.6 vs 13.7±5.3, P=0.016) and DHI-F (6.5±6.4 vs 13.0±7.2, P=0.002) in the vestibular group were lower, however, there was no significant difference in DHI-E score between the two groups (6.6±4.8 vs 9.6±7.3, P=0.087). Conclusion: Compared with otolith reposition, personalized vestibular rehabilitation therapy plays a better role in improving the symptoms and decreasing DHI score for patients with atypical BPPV.

ABSTRACT

PURPOSE: Through questionnaire survey, parents’ cognition of children’s bad oral habits and their related influencing factors were explored, in order to provide a reference for science popularization and education in future work.

METHODS: With a self-designed questionnaire, 247 parents of children at first visit were surveyed on basic information and problems related to bad oral habits. Descriptive statistics were used for the counting data. Logistic regression analysis was used for the relevant factors affecting the parents’ cognition of children’s bad oral habits with SPSS 26.0 software package.

RESULTS: Among 247 parents of preschool children, 17.4% of the parents took their children to the hospital for treatment because of bad oral habits. The prevalence of oral unhealthy habits was 44%. Parents’ knowledge of bad oral habits was not high, less than half of the parents (46.6%) knew about bad oral habits, of which 82.6% of the parents thought that bad oral habits would affect the development of children’s teeth, jaws, face and mental health, including facial contour (62.1%), dentition (34.7%), masticatory function (48.4%), and mental health (21.1%). 78.3% of the parents thought that bad oral habits needed to be corrected; 69.6% of the parents thought that they needed to go to the hospital for treatment, and 30.4% of the parents thought that it was ok as long as their children giving up bad oral habits. 61.7% of the parents would seek medical treatment in time when their children had bad oral habits. The ways for parents to obtain knowledge about bad oral habits were hospital education (61.5%). Parents with different characteristics had different cognition of bad oral habits. Logistic regression analysis showed that parents’ education background was a risk factor affecting parents’ cognition of bad oral habits(P=0.009).

CONCLUSIONS: Parents’ awareness of bad oral habits is not high, and parents’ educational background is a risk factor for parents’ awareness of bad oral habits. It is necessary to improve parents’ awareness of oral habits, strengthen health education of bad oral habits, especially for parents with special signs, and improve the attention to oral health care, to achieve early detection, early prevention, early treatment and timely treatment, so as to prevent the occurrence and development of malocclusion.

ABSTRACT

PURPOSE: To study the relationship between the expression of prostaglandin E2 (PGE2) and cyclooxygenase-2 (COX-2) and the osteogenic activity and oxygen level of alveolar bone.

METHODS: The alveolar bones of 56 patients with chronic periodontitis who received dental treatment from March 2021 to March 2023 were collected as the experimental (periodontitis) group, and the healthy alveolar bones of 53 patients who received dental treatment during the same period were selected as the control group. The osteoblasts were cultured by tissue block culture, and modified Kaplow’s alkaline phosphatase (ALP) staining was used to identify the cells. COX-2, PGE2 and osteoclastogenesis inhibitory factor (OPG) receptor activator of nuclear factor-κb ligand (RANKL) and other indicators were determined by ELISA. PGE2, COX-2, OPG, internal oxygen level, ALP, RANKL and their correlation were compared between the two groups. Statistical analysis was performed with SPSS 27.0 software package.

RESULTS: PGE2, COX-2 and RANKL in periodontitis group were significantly higher than those in the control group, but OPG, internal oxygen level and ALP were significantly lower than those in the control group (P＜0.05). PGE2 and COX2 were highly positively correlated with OPG, internal oxygen level and ALP, but were highly positively correlated with RANKL(P＜0.05).

CONCLUSIONS: The expression of PGE2 and COX-2 is highly negatively correlated with ALP and oxygen levels. Clinical treatment may consider increasing oxygen levels, increasing oxygen partial pressure, and regulating ALP levels by drugs, so as to change the inflammatory condition of periodontitis or other dental diseases.

ABSTRACT

PURPOSE: To analyze the effect of orthodontic treatment combined with bone level implant in repairing dentition defect.

METHODS: The data of 88 patients with single dental implant in mandibular posterior region who were treated for dentition defect from January 2020 to January 2022 were retrospectively analyzed, including 44 patients with bone level implant repair(control group) and 44 patients with orthodontic treatment combined bone level implant repair (experimental group). The success rate of implant implantation, periodontal health status, masticatory function, implant stability, postoperative complications and implant satisfaction were compared between the two groups. Statistical analysis was performed with SPSS 18.0 software package.

RESULTS: There was no significant difference in the success rate of implant implantation at 3 months and 6 months between the two groups(P＞0.05). The success rate of implant implantation at 12 months in the experimental group was significantly higher than that in the control group (P＜0.05). The gingival sulci bleeding index (SBI) and probing depth (PD) of the experimental group were significantly lower than those of the control group at 12 months after implantation (P＜0.05), and there was no significant different in bone absorption between the two groups at 12 months after implantation(P＞0.05). The EMG activities of masseter muscle and temporal muscle in the two groups were significantly higher than those before treatment(P＜0.05), and those of masseter muscle and temporal muscle in the experimental group were significantly higher than those in the control group (P＜0.05). The implant stability coefficient values of 6 months and 12 months in 2 groups were significantly higher than those of 3 months (P＜0.05), the implant stability coefficient values of 12 months in 2 groups were significantly higher than those of 6 months and 12 months in 2 groups (P＜0.05), and the implant stability coefficient values of 6 months and 12 months in the experimental group were significantly higher than those in the control group(P＜0.05). There was no significant difference in the total complication rate between the two groups (P＞0.05). The implant satisfaction of the experimental group was significantly higher than that of the control group (P＜0.05).

CONCLUSIONS: Orthodontic treatment combined with bone level implants can improve the success rate of implantation and masticatory efficiency, enhance the periodontal health of implants, and increase the patients’ satisfaction with implants.
