PURPOSE: To evaluate the clinical course of visual acuity and foveal thickness in the idiopathic epiretinal membrane (ERM) after a vitrectomy with the use of triamcinolone. METHODS: We retrospectively reviewed the records of 30 patients (30 eyes) with ERM that were treated by vitrectomy from 2004 to 2008. Visual acuity and foveal thickness from optical coherence tomography imaging was obtained preoperatively and at every postoperative follow-up visit. RESULTS: Visual acuity improved by two or more lines of vision in 30%, 50%, 60%, and 70%, and stayed the same within +/-1 line in 47%, 50%, 40%, and 30% at one month, three months, five months, and seven months after surgery. Twenty-three percents of the subjects deteriorated by two or more lines of vision within one month after surgery. None of the subjects had reduced vision three months after surgery. Foveal thickness decreased significantly after surgery. The mean thickness was 409.7+/-107.9 microm before surgery and 288.6+/-66.1 microm seven months after surgery. Parameters which were significantly correlated with the final visual acuity included preoperative visual acuity (0.683), preoperative foveal thickness (0.544), and final foveal thickness (0.643) (p<0.005). CONCLUSIONS: Foveal thickness and visual acuity improved until seven months after the vitrectomy in patients with idiopathic ERM. Preoperative visual acuity, foveal thickness, and final foveal thickness had a significant correlation with the final visual acuity.

2.Incidence of Calcification of the Trochlear Apparatus in the Orbit.
Korean Journal of Ophthalmology 2010;24(1):1-3
PURPOSE: To quantify the incidence of asymptomatic incidental trochlear calcifications and to describe their clinical features. METHODS: We retrospectively reviewed orbital computed tomography (CT) scans of 216 patients to identify the presence of trochlear calcifications. We analyzed the prevalence, age distribution, and gender preponderance of trochlear calcifications. We also examined age-specific prevalence rates for trochlear calcifications, as well as their relationship to systemic disease. RESULTS: The mean age of patients was 26.8 years. Trochlear calcifications were observed in 35 (16%) of the 216 patients, and 18 of the 35 patients had bilateral calcifications. The rate of trochlear calcification was higher in males; 32 (20.9%) of 153 male patients had trochlear calcifications, compared with 3 (4.8%) of 63 female patients. Age, hypertension, diabetes mellitus, and thyroid disease were not significantly associated with the incidence of trochlear calcifications. CONCLUSIONS: Incidental asymptomatic orbital calcification is more commonly observed on CT images than we expected and occurs predominantly in male patients. Understanding this to be a relatively common, benign finding may help us to rule out foreign bodies and other pathologic conditions.

Objectives:
This study examined the level of depression and anxiety and the related factors, especially the knowledge and attitudes towards dementia, of people caring for a family member with dementia.
Methods:
Data on the demographics, care burdens, and clinical characteristics of dementia patients and their family caregivers were collected. The Center for Epidemiologic Studies Depression Scale (CES-D) and Korean Screening Tool for Anxiety disorders (K-ANX), Dementia Knowledge Scale (DKS), and Dementia Attitudes Scale (DAS) were performed. This study investigated whether depression and anxiety of caregivers differed according to the caregivers, patients, and the burden of caregivers. Multiple regression analysis was performed to investigate the potential factors that may influence the psychological symptoms in family caregivers.
Results:
There were 135 respondents. The scores of CES-D and K-ANX were 19.18±12.05 (probable depression) and 11.48±8.88 (mild anxiety), respectively. There was a significant difference in the degree of depression according to the level of education (F=4.14, p<0.05), the severity of dementia (F=3.63, p<0.05), and cohabitation with patients with dementia (t=2.07, p<0.05). On the other hand, the difference in the degree of anxiety was not significant depending on the stratified potential factors. The degree of depression in caregivers was positively associated with severe dementia (β=0.252, p<0.01) and negatively associated with the DAS score (β= -0.392, p<0.001). Anxiety was only inversely affected by the DAS score (β=-0.369, p<0.001).
Conclusion
This study shows that family caregivers of people with dementia experience high levels of depression and anxiety, which are influenced by the patient’s severity of dementia and the caregiver’s attitude toward dementia.

PURPOSE: To evaluate the efficacy of transcatheter arterial embolization(TAE) in children with blunt splenicinjury. MATERIALS AND METHODS: The results of transcatheter splenic arterial embolization in nine children whosuffered splenic injury after blunt abdominal trauma were retrospectively studied. This injury was demonstrated byCT, and the findings were evaluated according to the classification of Mirvis et al. ; two patients were grade 3and seven were grade 4. All were carefully observed in intensive care before embolization. TAE was performed if apatient satisfied the following criteria : (1) transfusion and/or fluid replacement required to maintainhemodynamic stability ; or (2) rapid Hb/Hct decrease ; or (3) both. Splenic function was subsequently estimatedaccording to the results of 99mTc-sulfur colloid scintigraphy and/or CT scanning. RESULT: TAE was suscessful inall nine children. Two were embolized with a coil only, three with gelfoam, and four with gelfoam and a coil.Seven were embolized in the main trunk of the splenic artery and others in both the main trunk and its branches.Splenic function was preserved in all nine children, during follow-up, none suffered rebleeding. CONCLUSION: TAEof the splenic artery can be a safe and effective nonsurgical approach to the management of blunt splenic injuryin children, and can preserve splenic function.

PURPOSE: Liver function test abnormalities have been reported frequently in patients receiving total parenteral nutrition (TPN). In adults, it is known that liver complications decrease with the use of cyclic parenteral nutrition (CPN), especially if the shift to cycling was not too late. However, there are few studies about the effects of cycling on liver injury in children beyond the neonatal period. The aim of this study is to evaluate the effect of the early use of CPN on total parenteral nutrition induced hepatic dysfunction. METHODS: Twelve sets of CPN in 11 children (2 months to 17 years) were included in this study. Data on underlying diseases, age, length of time on TPN, macronutrient intake, complications, and biochemical parameters were collected from clinical records. All children had received CPN in the early period of persistent transaminase elevation or cholestasis complicated by previous continuous PN. The duration of infusion off-time in CPN was 2 hours in patients less than 3 months of age and 4 hours in the older children. RESULTS: All 12 cases showed elevated aminotransferase and 5 of them also showed cholestasis. Serum total bilirubin concentration was normalized in all 5 cases with median periods of 8 days (p<0.05) after initiation of CPN. ALT either decreased significantly or was normalized in all cases with median periods of 30 days (p<0.05) on CPN. The CPN was well tolerated without significant complication except for one case of hyperglycemia. CONCLUSION: The early use of cyclic parenteral nutrition had a beneficial effect in improving hepatic dysfunction complicated by TPN in children.

PURPOSE: A prospective, controlled trial was conducted to evaluate growth, bone mineralization, and nutritional status receiving preterm human milk supplemented with a newly formulated Maeil human milk fortifier. METHODS: Twenty five fortified human milk-fed and preterm formula-fed infants with a birth weight < 1, 800 g and gestational age <35 weeks, who were born at Ajou University Hospital from March, 2003 through August, 2004 were studied. Growth, biochemical indices of bone mineralization, feeding tolerance, morbidity and wrist X-ray were assessed serially. Total body bone mineral density was measured by dual energy X-ray absorptiometry at 2 and 5months of age. RESULTS: There were no differences in growth, including weight, height and head circumference, between two groups. Serum Ca, P, ALP and other biochemical indices were similar. Although low grade rickets (grade I and II) were occasionally found on wrist X-ray, the rate of occurrence and severity were similar. The bone mineral densities of both group showed no difference. CONCLUSION: The fortified human milk-fed infants and preterm formula-fed infants showed no difference in growth, and bone mineralization. This newly formulated Maeil human milk fortifier can be safely used in preterm infants.

Acute intermittent porphyria (AIP) is a rare disorder characterized biochemically by the increased excretion of porphyrins and porphyrin precursors, including delta-aminolevulinic acid (ALA) and porphobilinogen (PBG). AIP has variable clinical manifestations, such as acute abdominal pain, vomiting, nausea, constipation, peripheral neuropathy, seizures, tachycardia, and hypertension. A 16-year-old girl presented with recurrent abdominal pain, vomiting, hypertension, seizures, hypercholesterolemia, and red urine. AIP was confirmed by clinical features and increased 24-hour urine ALA and PBG. AIP should be considered in the differential diagnosis of patients who have abdominal pain, hypertension, and seizures when the results of all other tests are normal.

PURPOSE: The aim of this study is to investigate the seroepidemiology of hepatitis A and hepatitis B in Korean children. METHOD: 801 children aged 6 to 12 years were enrolled. IgG antibody to hepatitis A virus (anti-HAV), hepatitis B surface antigen (HBsAg), antibody to HBsAg (anti-HBs), and IgG antibody to HBc (anti-HBc) were measured by radioimmunoassay. RESULTS: Of the 801 children, the seroprevalence of anti-HAV was 0%. Three (0.4%) were seropositive for HBsAg. The seroprevalence of anti-HBs was 61.8%. Two (0.4%) of 495 anti-HBs positive subjects were positive for anti-HBc. Of the 801 children, 658 (82.1%) had received hepatitis B vaccination. CONCLUSIONS: Since natural anti-HAV is not acquired in the childhood, the outbreak of hepatitis A is possible in adolescents and young adults. The decrease in seroprevalence of HBsAg and the increase in seroprevalence of anti-HBs might result from hepatitis B vaccination program in childhood.

The purpose of this study was to measure the skin dose using the glass dosimeter and diode and to compare those measurements to the planned skin dose from the treatment planning system. For the reproducibility of the glass dosimeter (ASAHI TECHNO GLASS CIRPORATION, Japan), the same dose was irradiated to 40 glass dosimeters three times, among which 28 with the reproducibility within 3% were selected for the use of this study. For each of 27 breast cancer patients, the glass dosimeters and diodes were attached to 4 different locations on the skin to measure the dose during treatment. All the patients received one fraction of 180 cGy each. The maximum difference of measurements between the glass dosimeter and diode at the same location was 3.2%. Comparing with the planned skin dose from the treatment planning system (Eclipse v6.5, Varian, USA), the dose measured by the glass dosimeter and the diodeshowed on an average 3.4% and 2.3% difference, respectively. The measured doses were always less than the planned skin dose. This may be due to the specific errors of both detectors. Also, the difference may be caused by the fact that since the skin where the detectors were attached is pretty moveable, it was not fix the detectors on the skin.

Acute acalculous cholecystitis (AAC) is an inflammation of the gallbladder in the absence of demonstrated stones. AAC is frequently associated with severe systemic inflammation. However, the exact etiology and pathogenesis of AAC still remain unclear. Acute infection with Epstein Barr virus (EBV) in childhood is usually aymptomatic, whereas it often presents as typical infectious mononucleosis symptoms such as fever, cervical lymphadenopathy, and hepatosplenomegaly. AAC may occur during the course of acute EBV infection, which is rarely encountered in the pediatric population. AAC complicating the course of a primary EBV infection is usually associated with a favorable outcome. Most of the patients recover without any surgical treatment. Therefore, the detection of EBV in AAC would be important for prediction of better prognosis. We describe the case of a 10-year-old child who presented with AAC during the course of primary EBV infection, the first in Korea, and review the relevant literature.
