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: In order to evaluate the spectrum of mitochondrial DNA (mtDNA) mutations in the patients with suspected Leber's hereditary optic neuropathy (LHON). METHODS: We investigated 14 primary mtDNA mutations at nucleotide positions (nps 3460A, 4160C, 5244A, 9101C, 9804A, 10663C, 11778A, 13730A, 14459A, 14482G, 14484C, 14495G, 14498T, and 14568T) and one common secondary mutation (np15257A) in 82 Korean patients with suspected LHON. RESULTS: Among them, only three kinds of LHON mutations were identified in 60 (73%) of 82 probands, which were comprised of 46 (56%) cases with the 11778A, 13 (16%) with the 14484C, and 1 (1%) with the 3460A. None of the other mtDNA mutations was detected. Of the 60 probands with LHON positive mutations, 19 (32%) had relevant family histories. Heteroplasmy was determined in 2 (4%) of the 46 probands with the 11778A and 1 (8%) of 13 probands with the 14484C. CONCLUSIONS: In conclusion, the 11778A was the most common cause (56%), and higher prevalence of the 14484C and the lower prevalence of the 3460A were characteristic in Korean patients with LHON. Especially, the 3460A had a remarkable racial difference compared with Caucasians. Except 3460A, 11778A, and 14484C, the other mutations screened may not be involved in pathogenesis and not have a synergistic effect on the clinical expression of LHON in Koreans.

PURPOSE: Measles infection in children has been known to have many complications including hepatitis. But there has been no appropriate study about measles hepatitis in children. So we studied to facilitate the understanding of measles hepatitis in children by analyzing their clinical features and laboratory findings. METHODS: We investigated 164 patients who were admitted to the Department of Pediatrics, Seoul Red Cross Hospital due to measles from January 1985 to December 1994. We excluded other factors such as hepatitis A, B, C virus, Epstein-Barr virus and cytomegalovirus which could also result in hepatitis. According to the presence and the absence of coexistent complications 22 measles hepatitis patients were divided into two groups in which clinical characteristics and laboratory findings were analyzed as well. RESULTS: 1)Of total 164 patients there were 26 patients(15.9%) with measles hepatitis. 2)The ratio of male to female was 1.8:1. The range of age distribution was 6 months to thirteen years, and patients from 6 months to 3 years of age occupied 50% of the total patients. 3)The mean values of serum AST and ALT levels were 151+/-17.6 IU/L and 185+/-36.6 IU/L, espectively. And they were detected at 4.4+/-2.4 days after the first symptoms of measles were developed. 4)Major clinical characteristics were diarrhea in 22.7%, vomiting in 13.6%, hepatomegaly in 9.1%, and splenomegaly in 4.5%. Jaundice was not detected. 5)There was no difference between two groups in terms of serum albumin, globulin, bilirubin, AST and ALT(p>0.05). 6)Elevated serum AST and ALT levels returned to normal values within 2 weeks in 87.5%. CONCLUSIONS: Measles hepatitis develops with favorable outcome. Liver function test may well be done in cases of measles infection because hepatic dysfunction does not uncommonly occur in measles infection. Further study for the difference of the incidence of measles hepatitis according to the measles epidemics should be performed.

Leber's hereditary optic neuropathy (LHON) is a maternally transmitted disease causing acute or subacute, bilateral optic atrophy mainly in young men. It is found to be a mitochondrial disorder with the primary mitochondrial DNA (mtDNA) mutations at 11778, 3460, and 14484. The incidence of each mutation is reported to be race-dependent. Point mutations at mtDNA nucleotide position 11778 and 14484 have been reported in Korean patients with LHON, however there has been no report of mtDNA mutation at nucleotide position 3460. Molecular genetic analyses at four primary sites (11778, 14484, 15257, and 3460) of mitochondrial DNA using the polymerase chain reaction, restriction enzyme digestion, and direct sequencing were performed in a 35-yr-old man with severe visual loss. A point mutation in the mtDNA at nucleotide position 3460 was identified and a conversion of a single alanine to a threonine was confirmed. To our knowledge, this is the first report confirming mtDNA mutation at nucleotide position 3460 in Korean patients with LHON. Detailed molecular analyses would be very helpful for the correct diagnosis of optic neuropathy of unknown etiology and for genetic counseling.
