ABSTRACT
@#AIM: To analyze the anatomical characteristics of nasolacrimal duct development in children with congenital nasolacrimal duct obstruction by nasolacrimal duct CT scan combined with three-dimensional reconstruction technology.<p>METHODS: Prospective case control study. Totally 84 children(84 eyes)with unilateral congenital nasolacrimal duct obstruction were treated in the Department of Ophthalmology of Baoding Children's Hospital from September 2018 to September 2020. The nasolacrimal duct CT scan combined with three-dimensional reconstruction was performed. The transverse diameter and anterior posterior diameter of bilateral nasolacrimal duct were measured, and the anatomical characteristics of nasolacrimal duct development were observed and analyzed. Paired <i>t</i>-test was performed on the transverse diameter and anteroposterior diameter of bilateral nasolacrimal duct.<p>RESULTS: Nasolacrimal duct CT scan combined with three-dimensional reconstruction can clearly show the anatomical characteristics of nasolacrimal duct development in children with congenital nasolacrimal duct obstruction. The transverse diameter of bony nasolacrimal duct was 4.63±0.92mm, anterior posterior diameter was 6.03±1.08mm, the transverse diameter of middle bony nasolacrimal duct was 4.02±0.88mm, anterior posterior diameter was 5.42±1.10mm, the transverse diameter of final bony nasolacrimal duct was 4.26±0.93mm, anterior posterior diameter was 5.66±1.02mm. The transverse diameter of the bony nasolacrimal duct in the initial segment of the contralateral side was 4.12±0.78mm, the anteroposterior diameter was 5.60±1.02mm, the transverse diameter of the bony nasolacrimal duct in the middle segment was 3.92±0.86mm, the anteroposterior diameter was 5.24±1.04mm, the transverse diameter of the bony nasolacrimal duct in the final segment was 4.30±0.98mm, the anteroposterior diameter was 5.52±1.04mm. The transverse diameter and anteroposterior diameter of the affected side were larger than those of the healthy side and enlarged(<i>P</i><0.01). There was no significant difference between the affected side and the healthy side(<i>P</i>>0.05).<p>CONCLUSION:The development of bony nasolacrimal duct in the affected side of congenital nasolacrimal duct obstruction is different from that in the healthy side. The initial segment of the affected side expanded obviously.
ABSTRACT
@#AIM: To observe and analyze the therapeutic effect of fine training combined with virtual reality brain vision training in amblyopic children.<p>METHODS: Case control study. 232 cases(416 eyes)of amblyopia were diagnosed in Baoding children's Hospital for the first time. They were randomly divided into two groups. Group A was treated with fine training, while group B was treated with fine training combined with visual training. Duration of treatment was 6mo. The patients were followed up for 6mo. Objective to observe the clinical efficacy of amblyopia in children of different ages and degrees.<p>RESULTS: The total basic cure rate was 35.6%(74/208)in group A and 51.4%(107/208)in group B, which was higher than that in group A(<i>P<</i>0.01). The total effective rate was 80.8%(168/208)in group A, 91.3%(190/208)in group B, which was higher than that in group A(<i>P</i>=0.006). Therapeutic effect of each age group: the basic cure rates of group A were 55.9%(38/68), 34.9%(30/86), 11.1%(6/54)(<i>r</i>s=-0.76, <i>P<</i>0.01), respectively. The basic cure rates of group B were 70.6%(48/68), 54.6%(47/86), 22.2%(12/54)(<i>r</i>s=-0.78, <i>P<</i>0.01), respectively. The basic cure rate of group A and group B decreased with age. The effective rates of group A were 100%(68/68), 81.4%(70/86), 55.6%(30/54)(<i>r</i>s=-0.67, <i>P<</i>0.01), respectively. The effective rates of group B were 100%(68/68), 93.0%(80/86), 77.8%(42/54)(<i>r</i>s=-0.64, <i>P<</i>0.01), respectively. The efficiencies of A and B groups decreased with age. Therapeutic effect of amblyopia degree groups: the basic cure rates of group A were 63.3%(50/79), 25.0%(22/88)and 4.9%(2/41)(<i>r</i>s=-0.93, <i>P<</i>0.01), respectively. The basic cure rates of group B were 81.0%(64/79), 44.3%(39/88)and 9.8%(4/41),respectively(<i>r</i>s=-0.89, <i>P<</i>0.01). The basic cure rate of groups A and B was negatively correlated with the degree of amblyopia. The effective rates of group A were 83.5%(66/79), 79.5%(70/88), 78.0%(32/41)(<i>r</i>s=0.00, <i>P</i>=12.316), respectively. The effective rates of group B were 91.1%(72/79), 89.8%(79/88), 95.1%(39/41)(<i>r</i>s=0.00,<i> P</i>=15.603), respectively. There was no significant correlation between amblyopia severity and efficiency in groups A and B.<p>CONCLUSION: Fine training combined with virtual reality brain vision training is a safe and effective way to treat amblyopia. There is a certain correlation between the clinical efficacy and the age and the degree of amblyopia.
ABSTRACT
Acute coronary syndrome (ACS) and acute aortic syndrome (AAS) are both life-threatening emergencies. We report a case of ACS with thoracic aneurysm. Thoracic endovascular aortic repair (TEVAR) was arranged. However, perioperative complete atrioventricular block occurred and soon progressed to ST-elevation myocardial infarction. In the case of chest discomfort with elevated troponin I and thoracic aneurysm, it is of tremendous importance to cope with both ACS and the possible AAS. In the era of hybrid operation room, coronary catheterization and intervention first followed by TEVAR may provide timely and more comprehensive treatment.
