Eleven cases of arthroscopic ankle arthrodesis were reviewed. Average age of patients was 59 years, 4 male and 7 female. Underlying diseases were osteoarthritis in 7 cases, rheumatoid arthritis in 3 cases and one post-traumatic arthritis. At the mean follow up of 15 months, fusion rate was 100%, mean time to complete union was 9.5 weeks. There were no complications such as nonunion, infection and skin problems. All patients stayed at the hospital just overnight after the surgery. Patients satisfaction was high and the functional clinical grade was excellent in 9 patients, good in 1 patient and fair in 1 patient. We concluded that arthroscopic technique was a simple and effective method for ankle arthrodesis in the selected patients and had significant advantages over the open technique.

Objective To explore the impact of maternal hepatitis B (HBV) virus infection status on the vaccination effect of the offspring. Methods Eighty-six pairs of HBV-infected mothers and newborns who were treated in Dalian Sixth People<sup>'sup>s Hospital from 2017 to 2019 were selected as the research subjects. According to the strength of the hepatitis B vaccine response, all patients were divided into two groups, the observation group (none or weak response) and the control group (strong response). Hepatitis B virus infection was compared between the mothers of the two groups, and multivariate logistic regression was used to analyze the influencing factors of vaccination effect of the offspring. Results The positive rate of HBV DNA in mothers of the observation group was higher than that in the control group. HBV DNA was mainly at high load and HBeAg was at low level. The HBV DNA of the control group was mainly at low load, while the distribution of HBeAg was close. The difference was statistically significant (P < 0.05). HBV infection pattern in the observation group was <sup>"sup>HBsAg(+), HBeAg(+), anti-HBc(+)<sup>"sup> in 14 cases (51.85%), <sup>"sup>HBsAg(+), anti-HBe(+), anti- HBc(+)<sup>"sup> in 11 cases (40.74%) , while there were 27 cases (45.76%), 25 cases (42.37%), and 7 cases (11.86%), respectively, in the control group. The difference was statistically significant (P<0.05). Multivariate logisitic regression analysis showed that HBV DNA positivity, HBV DNA high load, HBeAg positivity, and low HBeAg levels were risk factors for weak response of the offspring vaccination. Conclusion HBV DNA positivity, high HBV DNA load, HBeAg positivity, and low HBeAg levels in HBV-infected mothers were risk factors for weak response of the offspring to vaccines, which should be paid attention to in clinic.

OBJECTIVES: This study aims to investigate the effectiveness of an internet-based anger management program for school-aged children. METHODS: Forty-eight elementary school students took part in an anger management training program; subsequently, participants, their parents, and their teachers answered questionnaires assessing the participants' anger, aggressiveness, and other emotional/behavioral problems, pre- and post-training. RESULTS: At the post-training self-assessment, the participants showed significant reductions in their "anger-out" tendencies and physical aggressiveness. In addition, the effects of the program on "anger-out" tendencies, aggressiveness, anger and peer relational problem were found to be more significant in participants who reported depressive symptoms. Teachers rated the participants' peer-relational problems as having decreased after the training. CONCLUSION: The proposed internet-based anger management program had a significant effect on the school-aged children's abilities to control their anger.

PURPOSE: The efficacy of 20-gauge and 23-gauge vitrectomy system was investigated in primary vitrectomy for rhegmatogenous retinal detachment. METHODS: Eyes that underwent primary vitrectomy without scleral buckling for the treatment of rhegmatogenous retinal detachment were followed up at least 6 months and were reviewed retrospectively. Anatomic results, functional outcomes, operation time and complications were compared between 20-gauge and 23-gauge groups. RESULTS: Among 59 eyes of 59 patients, the 20-gauge group had 29 eyes of 29 patients and 23-gauge group had 30 eyes of 30 patients. Anatomic success after a single operation was obtained in 23 eyes (79.3%) of the 20-gauge group and 28 eyes (93.3%) of the 23-gauge group. Recurrence occurred in 6 eyes (20.7%) in the 20-gauge and in 2 eyes (6.6%) in the 23-gauge group. Retinal reattachment in all of these eyes was obtained through reoperation. Visual acuity improved logMAR 0.2 or more in 19 eyes (65.5%) of the 20-gauge group and 20 eyes (66.7%) of the 23 gauge group (p=0.153, 0.215). The average operation time of the 23-gauge group was 80.2 minutes, which was significantly shorter than the 94.8 minutes of the 20-gauge group (p=0.008). Transient ocular hypertension and progression of lens opacity were the most common complications in the both groups. CONCLUSIONS: Twenty-three-gauge transconjuctival sutureless vitrectomy achieved outcomes comparable with 20-gauge vitrectomy, with significantly shorter operation time in repair of rhegmatogenous retinal detachment. It is considered as a viable alternative to 20-gauge vitrectomy in selected cases.

PURPOSE: To compare the changes in corneal topography between 23 gauge (G) pars plana vitrectomy (PPV) and 20 G PPV. METHODS: Forty-three eyes of 42 patients who underwent PPV were divided into 2 groups: 20G PPV (Group I, n=18) and 23 G PPV (Group II, n=25). Both groups were followed up over 3 months postoperatively. ORBSCAN II was performed to compare the corneal topographic change of 20 G PPV and 23 G PPV. RESULTS: In a 5 mm zone, significant postoperative change in the mean corneal surface cylinder was found between the 1st day and the 1st month in Group I, while no significant change was found in Group II. Postoperatively, the increase in the mean corneal surface cylinder in Group I was significantly higher than in Group II between the 1st day and the 1st month. Clinically significant astigmatism, induced by surgery, was found only in Group I one week after the operation. In a 3 mm zone, there was no significant change in the mean corneal surface cylinder in both groups postoperatively. The difference in the mean corneal surface cylinder between the 2 groups at the postoperative periods showed no significant change. Surgically induced astigmatism was significantly higher in Group I than in Group II between the 1st day and the 1st month postoperatively. CONCLUSIONS: PPV with the 23 G system is a sutureless transconjunctival surgery, which appears to be more effective due to insignificant corneal surface and astigmatic changes in the early postoperative period.

There are some controversies on the mechanism of the lumbar disc degeneration and disc prolapse. But,it is clear that many factors are related to the disc degeneration. Configurations of the lower lumbar and lumbosacral spine have long been proposed as one of the important factors of disc degeneration in these areas. To look for the configurational risk factors and the probability of disc degeneration by the combinations of these factors, we analyzed simple radiographs and MRI of 73 patients who complaints of low back pain and are between 20 years and 39 years of age. We performed chi-square test and multivariate logistic regression analysis: L4-5 disc degeneration and L5-Sl disc degeneration as dependent variables and lumbar lordosis, sacral inclination, height of intercrest line, transitional vertebra and facet joint asymmetry as independent variables. We could not find any of these variables significantly related to the L4-5 intervertebral disc degeneration. For L5-S1 disc degeneration, only the presence of transitional vertebra was signicantly related. When there is no transitional vertebra, the probability of disc degeneration is 9 times(8.889) as large as that of presence of transitional vertebra. The probability of L4-5 disc degeneration without the degeneration of L5-S1 is 3 times as large as that of degeneration of both of L4-5 and L5-S1 disc in case of the presence of transitional vertebra.

PURPOSE: To compare lens-save and simultaneous phacoemulsification with intraocular lens implantation in primary vitrectomy for phakic rhegmatogenous retinal detachment (RRD). METHODS: A retrospective comparative analysis of 54 consecutive eyes from 54 phakic RRD patients who underwent vitrectomy with a minimum of 12 months of follow-up was performed. The patients were divided into the vitrectomy group and the combined group (patients who underwent vitrectomy with concurrent cataract surgery). The main outcome measures were the best corrected visual acuity (BCVA), anatomical success rate, complications and cataract status according to LOCSIII grading. RESULTS: Baseline characteristics were similar in both groups, except for age and cataract status. The mean age was 46.9 year in the vitrectomy group (n = 20) and 60.5 years in the combined group (n = 34) (p < 0.001). The postoperative BCVA (log MAR) improved from 1.27 and 1.30 at baseline to 0.45 and 0.28 at 12 months (p < 0.05), respectively, which was not a significant difference between the 2 groups. In the vitrectomy group, cataract status was changed from 1.8 at baseline to 2.5 at 12 months (p = 0.001). Two patients (11.1%) had an additional cataract surgery performed. The primary anatomical success rate was 90.0% in the vitrectomy group and 94.1% in the combined group. CONCLUSIONS: The vitrectomy group and combined group had similar results in the repair of phakic RRD. Although postoperative cataract progression was noted, lens should be saved in vitrectomy for young patients, as significant cataract is uncommon.

PURPOSE: To evaluate the spectrum of mitochondrial DNA (mtDNA) aberrations in patients with suspected chronic progressive external ophthalmoplegia (CPEO) and to establish the molecular diagnostic method for CPEO in Koreans. METHODS: We performed mtDNA analyses for single deletions with long-range PCR and direct sequencing, and for the nine important point mutations including 3243A>G and 8344A>G with PCR/RFLP in muscles, bloods and paraffin-embedded muscle sections of 16 Korean patients with suspected CPEO. RESULTS: Three novel single mtDNA deletions were identified in three patients' muscles: 3159bp deletion from np 6657 to np 9815, 7591bp from np 8429 to np 16019, and 6191bp from np 7799 to np 13989. In addition, multiple mtDNA deletions were found in one patient. None of the blood specimen had mtDNA deletions even in the patients with mtDNA deletion in muscle. All single deletion junctions were flanked by direct repeats of 6-8 bp. None of the nine mtDNA point mutations were found in muscles, bloods or paraffin-embedded muscle sections. CONCLUSIONS: We identified three novel single deletions by mtDNA analyses in the muscles of 3 patients with CPEO. However, point mutations were not found. Furthermore, we established a molecular diagnostic method for CPEO in Korea. Long-range PCR and direct sequencing of the muscles were appropriate as a molecular diagnostic method for CPEO in Koreans.

PURPOSE:The effect of preoperative intravitreal bevacizumab (Avastin(R)) injection was investigated in primary vitrectomy for severe proliferative diabetic retinopathy. METHODS: Eyes that underwent vitectomy for proliferative diabetic retinopathy were followed up at least 6 months and were reviewed retrospectively. The authors reviewed functional outcomes, complications, and operation time between preoperative bevacizumab injection (group I) and non-injection groups(group II). RESULTS: Among 93 eyes of 87 patients, the injection group consisted of 44 eyes of 41 patients and the non-injection gauge group consisted of 49 eyes of 46 patients. The mean interval between injection and vitrectomy was 5.8 days. Final visual acuity significantly improved as compared to preoperative visual acuity, and group I showed better visual acuity than group II (p=0.008). Visual acuity improved logMAR 0.2 or more in 36 eyes in group I and 43 eyes in group II (p=0.167). The average duration of postoperative vitreous hemorrhage was 1.02 days in group I, and 4.02 days in group II (p=0.2.08). Recurrence of vitreous hemorrhage was not observed in group I or in 2 eyes of group II (p=0.274). Epiretinal membrane occurred in 2 eyes of group I, and in 9 eyes of group II (p=0.031). Only a single eye in group I had neovascular glaucoma after vitrectomy (p=0.527). The operation time of group I was 64.8 minutes, which was significantly shorter than 78.1 minutes of group II (p=0.018). CONCLUSIONS: Intravitreal bevacizumab injection before vitrectomy in proliferative diabetic retinopathy facilitated removal of the fibrovascular membrane, and leads to less postoperative complications and better functional outcomes. Intravitreal bevacizumab injection before vitrectomy can be considered as an effective preoperative adjuvant.
