Cone-beam CT analysis of occlusal planes between different vertical skeletal types of adult class Ⅱ malocclusions in Shandong province / 解剖学报

[Abstract] Objective To investigate the cant of the occlusal planes in Chinese adult class Ⅱ malocclusions with hypodivergent, normodivergent, and hyperdivergent facial vertical patterns using cone-beam CT. Methods The descriptive, cross-sectional study evaluated 123 cephalogram from CBCT(CCB) of patients in Department of Orthodontics, the Affiliated Hospital of Qingdao University. According to cephalometric analysis, 89 Chinese adult class Ⅱ patients were divided into three groups according to the angle between FH-MP and the angle between SN-MP. In comparison, 34 Class I normodivergent malocclusions individuals were selected as the control group. Comparing the cephalometric result between 4 groups. Results As expected,the hyperdivergent group had steeper anterior occlusal planes(14. 73±3. 76) . and posterior occlusal planes(21. 42±5. 77)., there was a significant statistical difference between the hyperdivergent group and other 2 groups in class Ⅱ patients (P<0. 05). The height of maxillary second molar increased from high angle group to low angle group (P<0. 01). Conclusion There are different characters of the occlusal planes in varied vertical facial pattern. The inclinations of anterior and posterior occlusal planes in Chinese class Ⅱ hyperdivergent group were steeper than other 3 groups. The difference of posterior occlusal plane inclination is mainly caused by the height of maxillary second molar.

Effects of can walking anterior and posterior capsule polishing combined with tension ring implantation on lens capsular stability after phacoemulsification for ultra-high myopia cataract / 中华显微外科杂志

Objective:To observe the effects of polishing the anterior and posterior capsule with irrigation/aspiration (I/A) injection needle and capsular tension ring (CTR) implantation on intraocular lens (IOL) capsular stability after phacoemulsification for ultra-high myopia with 2.0 mm coaxial micro incision.Methods:This is a prospective randomized controlled study. There were 40 patients(80 eyes) aged 46-72 years old with ultra-high myopia cataract. The grade of lens opacity was grade II-IV, and the diopter was -10 D - -24 D. During 2.0 mm coaxial micro incision phacoemulsification, adopt coin tossing method randomly, 1 eye was operated using the anterior and posterior capsule polishing 360° with I/A injection needle combined with CTR implantation as the experimental group(40 eyes), the other eye was neither polished nor CTR implantated as the control group(40 eyes). The operation interval of both eyes was less than 1 week. The size of anterior capsular orifice, effective intraocular lens position(ELP), IOL eccentricity and posterior capsular opacification(PCO) were recorded at 1 week, 1, 3 and 6 months after operation in outpatient clinic. Two independent sample t-test and Fisher exact probability test were used to compare the differences between the 2 groups. P<0.05 was defined significant difference. Results:During the follow-up period, there were no significant change in the anterior capsule area, IOL eccentricity and ELP in the experimental group. However in the control group, the anterior capsular area decreased gradually with time, and gradually IOL eccentricity increased and ELP decreased. There was no significant difference between the 2 groups in each observation index at 1 week after operation, but it was ELP that first showed the difference tendency( P<0.01). The ELP of the control group was significantly lower than that of the experimental group at 1, 3 and 6 months after operation( P<0.05). There was no significant difference in anterior capsule area and IOL eccentricity between the 2 groups at 1 and 3 months after operation( P>0.05), but there was a significant difference at 6 months( P<0.05). In terms of PCO, the incidence of PCO was 0%, 2.5% and 7.5% in the experimental group and 5.0%, 17.5% and 32.5% in the control group respectively at 1, 3 and 6 months after operation. The incidence of PCO in the experimental group was significantly lower than that in the control group( P<0.05). Conclusion:Ultra-high myopia with cataract are prone to have capsular contraction after operation, which is characterized by IOL instability and anterior capsular orifice narrowing gradually. Combined 360° anterior and posterior capsular polishing with tension ring implantation in operation can effectively maintain the stability of ELP, reduce the degree of contraction of anterior capsular orifice, reduce the eccentricity of IOL and the incidence of PCO. Polishing the anterior and posterior capsule with I/A injection needle combined with CTR implantation, is safe and effective for patients with ultra-high myopia cataract.

Application of T-hook pre-chopping combined with capsule fine treatment technology in cataract surgery for high myopia / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To explore the clinical efficacy of the T-hook pre-chopping combined with capsule fine treatment technology for patients with high myopia and cataract.<p>METHODS: From March 2016 to February 2019, 56 cases(80 eyes)of cataract patients with high myopia were treated in cataract department of Hebei Province Eye Hospital. They were randomly divided into A and B groups, 40 eyes in each group. Group A underwent T-hook pre-chopping combined with fine capsular treatment. Cataract phacoemulsification combined with intraocular lens implantation was purely performed in group B. We compared the cumulative release energy of ultrasound during operation between the two groups. We also observed the best corrected visual acuity(BCVA), the amount of contraction of the anterior capsule, the degree of posterior capsule opacification, intraocular lens neutrality and complications for more than 6mo.<p>RESULTS: The cumulative release energy of ultrasound in group A was less than that in group B(12.23±3.61 <i>vs</i> 20.46±4.61, <i>P</i><0.01). The best corrected visual acuity of group A was better than that of group B at 6mo after operation(<i>Z</i>=5.328, <i>P</i>=0.002). The changes of anterior capsular contraction and intraocular lens decentration(0.18±0.14, 0.02±0.007mm)were less than those of group B(0.82±0.23, 0.65±0.240mm)(<i>P</i><0.05). In group A, there were 3mm round holes in the center of the posterior capsule, and the optic axis area remained transparent, while in group B, 13 eyes(32%)had turbid central area of the posterior capsule. In group A, there was no intraoperative posterior capsule rupture or postoperative retinal detachment. In group B, there were 2 eyes(5%)with intraoperative posterior capsule rupture and 1 eye(2%)with postoperative retinal detachment.<p>CONCLUSION: We used T-hook pre-chopping combined with capsule fine treatment technology to treat cataract with high myopia, which could reduce the use of ultrasound energy during operation, reduce the risk of posterior capsule rupture, effectively avoid the occurrence of posterior cataract, and achieve satisfactory clinical effect.

Effect of capsular LECs removal on capsular stability in patients with high myopia and cataract / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To investigate the effect of LECs removal on the stability of lens capsule bag in patients with high myopia.<p>METHODS: From March 2018 to April 2019, 98 cases(120 eyes)of cataract patients with high myopia were treated in Cataract Department of Hebei Province Eye Hospital. They were divided into two groups according to whether the LECs were removed during the operation. In group A, the anterior and posterior capsule were polished in 50 cases(60 eyes), while in group B, 48 cases(60 eyes)were not polished. During the follow-up period we used anterior segment OCT to detect the change of effective intraocular lens position(ELP), the eccentricity of intraocular lens(IOL)and the reduction of anterior capsule opening in the two groups, and used slit lamp to observe the occurrence and degree of PCO.<p>RESULTS: We compared the changes of ELP(0.16±0.06mm <i>vs</i> 0.55±0.07mm)and the changes of contraction of anterior capsule(0.18 ± 0.16mm <i>vs</i> 0.92 ± 0.13mm)on the first day and three months after operation. Three months after operation, we compared the IOL eccentricity of the two groups(0.02±0.005mm <i>vs</i> 0.69±0.23mm). There were differences between the two groups(<i>P</i><0.05). At 3mo after operation, the PCO of group A was observed by slit lamp: grade I 4 eyes, grade II 2 eyes, grade III 1 eye. The PCO of group B: grade I 16 eyes, grade II 8 eyes, grade III 4 eyes and grade IV 3 eyes. There was significant difference between the two groups(<i>Z</i>=-4.765, <i>P</i><0.01).<p>CONCLUSION: The removal of LECs could reduce the contraction of anterior capsule, decrease the change of ELP and enhance the stability of bag IOL complex, which played a good role in reducing PCO.

Long-term effect on corneal curvature of corneal collagen cross-linking for keratoconus

Objective@#To determine the effect of corneal collagen cross-linking on the corneal curvature of eyes with keratoconus measured using an Oculus Pentacam® at 2 years and annually thereafter. @*Methods@#This was a descriptive, retrospective study involving patients with keratoconus who had undergone uncomplicated collagen cross-linking using the Dresden protocol from January 2012 to March 2016. Baseline measurements of best-corrected visual acuity (BCVA), maximum K value (Kmax), corneal astigmatism, anterior and posterior elevation map changes were recorded and compared with data taken at 2 and 3 years@*Results@#This study included 32 patients (48 eyes) with a mean follow-up of 28.88 ± 6.23 months. Only 4 patients (6 eyes) had 3-year follow-up data with a mean follow-up of 42.83 ± 4.58 months. When all eyes were considered, significant changes were noted in Kmax, BCVA, and anterior and posterior elevation maps between baseline and 2-year follow-up. Specifically, there were significant decreases in Kmax (p<0.0001) and anterior elevation (p<0.05), and significant improvement in BCVA (p<0.01) while posterior elevation (p<0.0001) was found to have increased significantly at 2nd year follow-up compared to baseline. When only eyes with 3-year follow-up data was analyzed, only BCVA showed significant change (p<0.05). Corneal astigmatism remained stable during the study period.@*Conclusion@#Two to 3 years after collagen cross-linking for keratoconus, corneal curvature parameters and BCVA showed improved and stable outcomes when compared to baseline.

Methods: Between May 2011 and May 2016, Sixty-two patients with complicated acetabular fractures were treated with operation via combined anterior and posterior approaches. Thirty-four cases (group A) were treated with modified ilioinguinal approach combined with K-L approach, and 28 cases (group B) were treated with Stoppa approach combined with K-L approach. There was no significant difference in gender, age, injury causes, the type of fracture, time from injury to operation, and associated injury between 2 groups ( P>0.05). The operation time, intraoperative blood loss, and hospitalization time were recorded. X-ray film was performed to evaluate the fracture reduction according to the Matta reduction criteria and observe the fracture healing, osteoarthritis, and heterotopic ossification. Clinical results were evaluated according to the grading system of modified d'Aubigne and Postel. Results: There was no significant difference in operation time, intraoperative blood loss, and hospitalization time between 2 groups ( P>0.05). Postoperative incision fat liquefaction occurred in 2 cases in group A and group B respectively, and deep vein thrombosis of lower extremity occurred in 1 case in group A. No iatrogenic injury was found in 2 groups. Fifty-six patients were followed up after operation. Thirty patients in group A were followed up 12-48 months (mean, 31.8 months). Twenty-six patients in group B were followed up 12-46 months (mean, 30.2 months). At 12 months after operation, according to the grading system of modified d'Aubigne and Postel, the hip function was rated as excellent in 9 cases, good in 16 cases, fair in 3 cases, and poor in 2 cases, with the excellent and good rate of 83.3% in group A; the hip function was rated as excellent in 7 cases, good in 14 cases, fair in 2 cases, and poor in 3 cases, with the excellent and good rate of 80.8% in group B. There was no significant difference in the hip function between 2 groups ( Z=0.353, P=0.724). The X-ray films showed that there were 23 cases of anatomical reduction, 6 cases of satisfactory reduction, and 1 case of unsatisfactory reduction in group A, and 20 cases, 5 cases, and 1 case in group B, respectively. There was no significant difference in the results of fracture reduction between 2 groups ( Z=0.011, P=0.991). Fracture healing was observed in both groups. There was no significant difference in fracture healing time between 2 groups ( t=0.775, P=0.106). During follow-up, 5 cases of osteoarthritis changes, 2 cases of heterotopic ossification, and 2 cases of avascular necrosis of femoral head occurred in group A, and 4 cases, 2 cases, and 1 case in group B, respectively. The difference between 2 groups was not significant ( P>0.05). Conclusion: According to the location and type of fracture, making a choice between the modified anterior approach and Stoppa approach, and then combined with K-L approach for treatment of complicated acetabular fracture, can obtain satisfactory effectiveness.

A novel smartphone ophthalmic imaging adapter: User feasibility studies in Hyderabad, India.

Aim of Study: To evaluate the ability of ancillary health staff to use a novel smartphone imaging adapter system (EyeGo, now known as Paxos Scope) to capture images of sufficient quality to exclude emergent eye findings. Secondary aims were to assess user and patient experiences during image acquisition, interuser reproducibility, and subjective image quality. Materials and Methods: The system captures images using a macro lens and an indirect ophthalmoscopy lens coupled with an iPhone 5S. We conducted a prospective cohort study of 229 consecutive patients presenting to L. V. Prasad Eye Institute, Hyderabad, India. Primary outcome measure was mean photographic quality (FOTO‑ED study 1–5 scale, 5 best). 210 patients and eight users completed surveys assessing comfort and ease of use. For 46 patients, two users imaged the same patient’s eyes sequentially. For 182 patients, photos taken with the EyeGo system were compared to images taken by existing clinic cameras: a BX 900 slit‑lamp with a Canon EOS 40D Digital Camera and an FF 450 plus Fundus Camera with VISUPAC™ Digital Imaging System. Images were graded post hoc by a reviewer blinded to diagnosis. Results: Nine users acquired 719 useable images and 253 videos of 229 patients. Mean image quality was ≥ 4.0/5.0 (able to exclude subtle findings) for all users. 8/8 users and 189/210 patients surveyed were comfortable with the EyeGo device on a 5‑point Likert scale. For 21 patients imaged with the anterior adapter by two users, a weighted κ of 0.597 (95% confidence interval: 0.389–0.806) indicated moderate reproducibility. High level of agreement between EyeGo and existing clinic cameras (92.6% anterior, 84.4% posterior) was found. Conclusion: The novel, ophthalmic imaging system is easily learned by ancillary eye care providers, well tolerated by patients, and captures high‑quality images of eye findings.

Age-related Outcome of Arthroscopic Repair of Isolated Type II Superior Labral Anterior to Posterior Lesions

BACKGROUND: Repair of superior labral anterior to posterior (SLAP) lesion in patients older than 40 years is controversial. The purpose of this study was to evaluate clinical outcomes of arthroscopic repair of SLAP lesions between younger and older patient groups. METHODS: We reviewed 50 patients with isolated type II SLAP lesions who underwent arthroscopic repair. Patients were divided into 2 groups: group 1 included 20 patients aged or =40 years. Functional outcome at the final follow-up was assessed using a visual analog scale for pain and satisfaction, American Shoulder and Elbow Surgeons form, Constant score, University of California at Los Angeles score, and periodic change in range of motion (ROM). Anatomical outcome was evaluated using computed tomography (CT) arthrography at least 1 year after surgery. RESULTS: No significant differences in functional scores or postoperative ROM were observed between the 2 groups. In group 2, later recovery of ROM (forward flexion, p=0.025; internal rotation, p=0.034) and lower satisfaction score (p=0.06) were observed for atraumatic patients (n=16) compared to patients with traumatic injury (n=14). Fifteen patients in group 1 (15/17, 88%) and 21 patients in group 2 (21/26, 81%) demonstrated a healed labrum on postoperative CT arthrography, and this difference was not significant. CONCLUSIONS: The results of this study suggest that arthroscopic repair of type II SLAP lesions can yield good functional and anatomical outcomes regardless of age, if patient selection is adequate. However, the delay in ROM recovery and lower satisfaction, particularly in older patients without traumatic injury, should be considered.

Higher division of popliteal artery: a case report.

During the routine dissection of anatomy in an adult male cadaver at the department of anatomy, Manipal University, Manipal, higher division of popliteal artery was observed on the right side. This artery divided proximal to upper border of popliteus muscle into anterior and posterior tibial arteries. Inferomedial genicular artery which is usually a branch of popliteal artery was found to be arising from anterior tibial artery. However arterial branching pattern and point of bifurcation of popliteal artery on the left side were usual. The knowledge of these variations will be useful for angiography or various surgical approaches during knee joint surgery.
