Achondroplasia is a congenital disorder resulting from a specific disturbance in endochondral bone formation. The ophthalmic features reportedly associated with achondroplasia are telecanthus, exotropia, inferior oblique overaction, angle anomalies and cone-rod dystrophy. This is first report of chorioretinal coloboma in achondroplasia. An 8-year-old female was diagnosed with a developmental delay, known as achondroplasia, seven months after birth. Upon her initial visit, visual acuity was 0.3 in both eyes. The patient had telecanthus but normal ocular motility. Findings were normal upon anterior segment examination. Fundus examination of both eyes revealed about 1,500 microm sized chorioretinal coloboma inferior to the optic nerve head. Upon fluorescent angiography, there was chorioretinal coloboma without any other lesions. Afterward, there was no change in the fundus lesion, and best corrected visual acuity was 0.6 in both eyes. Chorioretinal coloboma is associated with choroidal and retinal detachment. As chorioretinal coloboma and achondroplasia are developmental disorders in the embryonic stage, early detection and regular ophthalmologic examination would be essential in patients with achondroplasia.

PURPOSE: To evaluate the pattern VEP in adult amblyopic patients seen in consultation for ophthalmic evaluation as a past of physical examinations for conscription. METHODS: We retrospectively analyzed, 67 men, 20-year-old or older, who had pattern VEP done for the diagnosis of amblyopia from January 2004 to May 2009. P100 latency and P100 amplitude were analyzed. RESULTS: Thirteen patients were non-amblyopic, and 54 patients had amblyopia. Binocular amblyopia and monocular amblyopia were found in 23 and 31 patients, respectively. In the binocular amblyopic patients, four patients were hyperopic, seven patients were myopic, and 12 patients were astigmatic amblyopia. In the monocular amblyopic patients, 15 patients were anisometropic, 12 patients were strabismic, and four patients had organic amblyopia. The value of P100 latency and P100 amplitude were statistically significantly different between non-amblyopic and amblyopic eyes, with check size of 32x32. However, the types of amblyopia among the patients were not different at a statistically significant level. Visual acuity and P100 amplitude were significantly positively correlated. CONCLUSIONS: VEP might be a useful tool for diagnosis of adult amblyopia, especially using a 32x32 check size. This tool may impart the ability to decide relationship between amblyopia and visual acuity by analyzing P100 latency and amplitude values.

PURPOSE: To examine the fate of muscle-derived stem cells (MDSC) after injection into different host conditions and provide an insight for their mechanism of action. MATERIALS AND METHODS: MDSCs differentiated in vitro towards the endothelial lineage and transfected with lentivirus tagged with green fluorescent protein (GFP) were injected into two animal models mimicking vascular diseases: hindlimb ischemia and carotid injury models. Injected cells were tracked at the site of injection and in remote organs by harvesting the respective tissues at different time intervals and performing immunofluorescent histological analyses. Stem cell survival was quantified at the site of injection for up to 4 weeks. RESULTS: MDSCs were successfully tagged with fluorescent material GFP and showed successful implantation into the respective injection sites. These cells showed a higher affinity to implant in blood vessel walls as shown by double fluorescent co-stain with CD31. Quantification of stem cell survival showed a time-dependent decrease from day 3 to 4 weeks (survival rate normalized against day 3 was 72.0% at 1 week, 26.8% at 2 weeks and 2.4% at 4 weeks). Stem cells were also fo und in distant organs, especially the kidneys and liver, which survived up to 4 weeks. CONCLUSION: MDSCs were successfully tracked in different vascular disease models, and their fate was assessed in terms of cell survival and distribution. Better understanding of the donor cell properties, including their interaction with the host conditions and their mechanism of action, are needed to enhance cell survival and achieve improved outcomes.

OBJECTIVE: To evaluate the effect of IL-10 on development of collagen-induced arthritis, on humoral and cellular immunity and on the endogenous production of IL-10 in DBA/1J mice. METHODS: DBA/1J mice were immunized with chicken type II collagen in Freund s complete adjuvant. Murine recombinant IL-10 was given intraperitoneally twice a week from the day of second immunization (week 3) in doses of 0.002ug, 0. 02ug and 0. 2ug for 3 different groups, respectively. Dexamethasone was injected in one group to suppress the arthritis development and this group was used as negative control group. Levels of anti-collagen antibodies, serum IL-10 and stimulation indices of splenic monocytes to collagen were measured at the end of study. RESULTS: The 0. 02ug IL-10 and 0. 2ug IL-10 treated groups developed earlier and more severe arthritis (week 6 and 8) compared to that of the control group while the 0. 002ug IL-10 group has shown similar course to the control group in terms of incidence and severity of arthritis, At week 10, all groups with or without IL-10 injections developed arthritis with similar degree of severity while dexamethasone group showed far less incidence and severity of arthritis. The serum levels of anti-collagen antibody, IL-10 and spleen monocyte stimulation indices to collagen antigen showed no difference among control group, IL-10 injected groups and dexamethasone injected group. CONCLUSION: This study shows IL-10 could worsen the arthritis in CIA with the dosage used in this study without significant influence on the level of anti-collagen antibodies or stimulation indices of spenic monocyte to collagen.

PURPOSE: The purpose of this study was to investigate the effect of the asthma management educational program given to the allergic asthmatics receiving immunotherapy due to house dust mite on the disease related to knowledge, stress, and self-efficacy. METHOD: The subjects of this study were the patients received immunotherapy to house dust mite at a week interval after being diagnosed for house dust mite allergic asthma at the respiratory center of a hospital affiliated to the university. They were divided into the experimental group of 29 patients who received asthma management education, the control group of 32 patients, and 61 patients in total. Experimental treatment, as an asthma management educational program, was the group education of one time and the reinforcement education of three times with environmental therapy and immunotherapy to house dust mite. RESULTS: The results revealed that the improvement in disease related knowledge, the improvement in self-efficacy and the decrease in stress, were significantly higher in the experimental group than the control group. CONCLUSIONS: The asthma management educational program had an effect on improving the disease related knowledge and self-efficacy, and decreasing the stress of the patients asthmatics allergic to house dust mite.

7.Impact of Perceived Parenting Styles on Depression and Smartphone Addition in College Students.
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2015;24(2):127-135
PURPOSE: The purposes of this study were to examine differences in depression and smartphone addiction among four styles of perceived parenting, and determine whether the perceptions of paternal and maternal parenting are associated with depression and smartphone addiction among college students. METHODS: A cross-sectional descriptive correlational design was used. A convenience sample of 378 undergraduate students responded to the survey. Data were analyzed using ANOVA, Pearson correlation, and multiple regression with IBM SPSS statistics version 21. RESULTS: Levels of depression and smartphone addiction were significantly different according to the four styles of perceived parenting (optimal parenting, affectionate constraint parenting, affectionless control parenting, and neglectful parenting). Scores of depression and smartphone addiction in the group with perceived affectionless control parenting were higher than those in the other groups. In a regression model, maternal care and paternal overprotection were significantly associated with depression. Also, maternal overprotection was the only significant predictor of smartphone addiction. CONCLUSION: These results suggest that students who perceive that both fathers and mothers are low in care, warmth, and support; but high in overprotection, control and intrusiveness are vulnerable to depression and smartphone addiction. Targeted interventions to change and reframe students' perception of paternal and maternal parenting in a positive way may reduce their depression and smartphone addiction.

BACKGROUND:Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general etiology. This study was performed to support the viral infection rather than the ischemic theory. MATERIALS & METHODS:We studied seventy years old female patient who showed painful vesicles on left auricle and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test, pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction. RESULTS:We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR. CONCLUSION:This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies to find the etiology of vestibular neuronitis are required.

PURPOSE: The purpose of this study was to investigate the relationship among family functioning, empathy and aggression by high school students. METHODS: This was a descriptive study. The survey participants were 467 high school students from M city. Data were collected from November 29 to December 7, 2012 and self-report questionnaires including a Family Adaptability Cohesion Evaluation Scale, Interpersonal Reactivity Indexes, and an Aggression Questionnaire. The collected data were analyzed by descriptive statistics, independent-samples t-test, ANOVA, stepwise multiple regression. RESULTS: The majority of the subjects were 2nd graders (42.0%) and female (57.2%). 59.7% of the subjects had religion, 84.8% were living together with parents. The mean ages of their fathers and mothers were 49.90+/-0.20 and 46.85+/-0.19 respectively. Aggression was found to have a statistically negative correlation with family functioning and empathy. Stepwise multiple regression analysis revealed that the most powerful predictor of aggression was empathic concern. Empathic concern, family cohesiveness, perspective taking, personal distress and gender accounted for 16.7% of the variances. CONCLUSION: It is necessary to provide aggressiveness reduction programs for high school students that consider their family functioning and empathy.

We have experienced a case of occult hepatocellular carcinoma metastasized to the heart in a 41 year old female. The hepatocellular carcinoma invaded the hepatic vein, grew in a snakelike fashion up the inferior vena cava and reached the right atrium. Ultrastural examination in this case confirmed the hepatocellular origin of the tumor.
