Hertel and Naugle exophthalmometers were used to compare the variability and reproducibility, produced by various observers. Five examiners measured fifty two eyes of twenty-six normal subjects each by using two different exophthalmometers, respectively. The average coefficient of variation among five measurements was 5.6% in the right eye, 5.2% in the left eye and 2.1% in base line by Hertel exophthalmometer. The average coefficient of variation measured by Naugle exophthalmometer was 1.9% in both eyes and 0.8% in pupillary distance. In conclusion, Naugle exophthalmometer showed less variability and better reproducibility; it is more appropriate for comparative exophthalmetry.

PURPOSE: Headache is a common neurologic symptom in children but chronic headache in them must be diagnosed in different ways. The aim of this study is to determine the algorithm of diagnostic approach for children with chronic headache and know the clinical significance of dizziness in evaluating those children. METHODS: We recruited children with headache at Myongji Hospital from January 2004 to July 2006. The study was based on a retrospective review of their medical records and interviews with the children and their parents. We divided them into two groups : Group A headache with dizziness, Group B headache without dizziness. RESULTS: The medical records of 86 children and adolescents with headache were reviewed. Age for group A ranged from 10 to 15 years(73.7%) and gender ratio was 1:1.7. Age for group B ranged mostly under 7 years(56.3%) and gender ratio was 1:0.85. Headache in group A frequently occurred predominantly in the morning(37.3%). The duration of the attack was over 90 min(87.5%) in group A and over 90 min(50.0%) in group B. Associated symptoms were mainly nausea(34.2%), vomiting(18.4%), blurred vision(12.7%) in group A. Over 90% of them had headache 4 times a week and so did dizziness. The final diagnoses in cases of group A were migraine(31.6%), orthostatic hypotension(15.8%), postural orthostatic tachycardia syndrome(13.2%), and benign paroxysmal positional vertigo(10.5%). While in group B diagnoses included sinusitis(50.0%), migraine(31.3%), and complications of migraine(8.3%). CONCLUSION: This study revealed high percentage of headache concurred with dizziness in children. The association of headache with dizziness is complex and maybe coincidental. If chronic headache with dizziness in girls occurs mainly in the morning, it maybe related to vestibular disorder and orthostatic instability. In conclusion, dizziness and other associated symptoms or clinical features should carefully be assessed in the diagnosis of headache.

It is known that surgically induced astigmatism can be reduced by incision along the steep axis. Also, high grade astigmatism can be induced by pterygium. We evaluated the amount of corneal astigmatism according to the severity of pterygium in cataract patients. We retrospetively analysed the change of astigmatism after simultaneous surgery for cataract and pterygium retrospectively. We divided patients into two groups, temporal incision group. We confirmed that astigmatism is induced by moderate to severe pterygium. The more severe the pterygium, the more the amount of astigmatism. The amount of astigmatism was reduced after surgery irrespective of the incision. Postoperative astigmatic change was stabilized earlier in the temporal incision group than in the superior incision group. We concluded thath simultaneous surgery for cataract and pterygium can be considered when the severity of the pterygium is moderate to severe. Incision location in those surgeries should be decided according to whether the previous astigmatism was with-the-rule or aganinst-the-rule and this can be assumed by the state of astigmatism of the healthy, fellow sys. If the assumption is not possible, temporal incision is more desirable in aspectes of stability and predictability of postoperative astigmatism.

We present a case of extensive thrombosis in the jugular vein and sigmoid, transverse, superior sagittal sinuses with partial deep venous thrombosis. The patient had acute severe headache but had neither focal neurological deficit nor consciousness change. Emergency endovascular thrombolysis through transfemoral approach was performed with successful restoration of venous drainage. There was no hemorrhagic complication. Several days later, the patient had a focal seizure attack due to focal venous infarction despite of continuous systemic anticoagulation therapy.

Journal of the Korean Child Neurology Society 2006;14(1):121-126
PURPOSE: We intended to investigate the clinical features and the predictors of febrile seizure plus(FS+), not suspected of generalized epilepsy with febrile seizure plus (GEFS+). METHODS: We selected 24 patients, aged more than 6 years old, who were admitted to Myongji Hospital of Kwandong University from January, 2001 to March, 2005 due to febrile seizures. All of those had neither a family history of febrile seizures or epilepsy nor abnormalities in the EEG or MRI. We examined sex, age of seizure onset, type of seizure, duration of seizure, the time until seizure after fever and frequency of febrile seizure. We investigated also the statistical significances of these clinical features by comparing with patients of simple febrile seizure(FS) as a control group. RESULTS: The male to female of the FS+ group was 2:1, which had no statistical significance compared with the FS. The age of seizure onsets in the FS+(39.4+/-5.0 months) was significantly older than FS the group(24.1+/-2.1 months)(P<0.05). In the types of seizures, non-generalized tonic clonic seizures occurred significantly more often in the FS+ group(20.9%) than the FS(8.4%)(P<0.05). The frequency of febrile seizures also was high in the FS+ group(n=3.2+/-0.8) than the FS group(n=1.1+/-0.1)(P<0.05). The duration of seizures and the time until seizure after fever did not have statistical significance. CONCLUSION: We suggest that FS+ can be characterized by late onsets of initial seizures, more frequent non-generalized tonic clonic seizures and recurrent febrile seizures. Therefore, FS+ should be suspected for patients more than 4 years old with non-generalized tonic clonic seizures or recurrent febrile seizures of more than 4 times.

This study was conducted to identify the major dietary patterns of Korean adult men and to examine the relationship between subjective stress perception and these dietary patterns using data from the 2014∼2016 Korean National Health and Nutrition Examination Survey (KNHANES). Of the 23,080 total subjects, adult men between the ages of 19 and 64 who did not take the questionnaire or answer the questions relating to depression, and cases where the daily energy intake was less than 500 kcal or more than 5,000 kcal in the Food Frequency Questionnaire were excluded. This left a total of 3,464 subjects who were included in the final analysis. We performed a factor analysis based on the yearly mean intake frequency of 41 food groups to identify the major dietary patterns. Three major dietary patterns were identified (factor loading >0.3), including the ‘Healthy pattern’, ‘Processed meat pattern’, and the ‘Alcohol pattern’. The ‘Healthy pattern’ was characterized by higher intake of beans, tofu, vegetable, fish, and fruits. The ‘Processed meat pattern’ was characterized by high consumption of processed meats and instant foods. The ‘Alcohol pattern’ was characterized by a higher intake of alcohol. As a response to the subject's subjective perception of stress, the most answered 'a little' according to age, marital status, occupation, income, residential area, smoking status, drinking status, and exercise status. People whose diets followed the ‘Processed meat’ and ‘Alcohol’ patterns had significantly higher scores on subjective stress perception compared to people following the ’Healthy pattern’.To manage subjective stress, it is more effective to maintain health by relieving stress through a healthy method that combines healthy eating and exercise rather than following an unhealthy diet as characterized by the ‘processed meat’ and ‘alcohol’ dietary patterns.

This study was conducted to assess the relationship between estimated glomerular filtration rate (eGFR) and bone mineral density (BMD) in Korean postmenopausal women with mild renal dysfunction. A total of 328 postmenopausal women who underwent BMD measurement during health check-up was investigated. BMD was measured in lumbar spine (L1-L4), femoral neck, total proximal femur and femoral trochanteric areas by dual energy radiography absorptiometry and renal function was estimated by eGFR using Cockcroft-Gault equation. Of the 328 subjects, 317 (96.6%) had an eGFR > or =60 mL/min/1.73 m2. By using simple linear regression analysis, age, height, weight and eGFR were significantly associated with BMD for the 4 aforementioned anatomic sites, while serum levels of creatinine and blood urea nitrogen did not influence BMD. When multiple regression analyses were applied, age and body weight still had significant associations with BMD at 4 different anatomic sites (P < 0.001). A significant association of eGFR with BMD remained in the lumbar spine, femoral neck and proximal total femur (P < 0.05) but not in the trochanteric area (P = 0.300). Our study suggests that a decline of renal function is associated with lower BMD in the lumbar spine, femoral neck and total proximal femur areas in Korean menopausal women with mild renal dysfunction.

Journal of the Korean Pediatric Society 1998;41(4):451-455
PURPOSE: The universal vaccination against hepatitis B during early infancy is the only effective way to control hepatitis B infection in highly endemic areas in Korea. The purpose of this study was to assess the effectiveness of simultaneous hepatitis B vaccination with DPT and oral polio at 2, 4, 6 months of age in babies of HBs antigen negative mothers. METHODS: One hundred and eighty-one infants who were admitted to the Neonatal Intensive Care Unit (NICU), Chonnam University Hospital from August, 1994 to December, 1995 were enrolled in this study. Infants received Hepavax-B 0.5ml (10 microgram) at contralateral thigh intramuscularly, simultaneously with DPT vaccination. Antibody was assessed by MEIA (microparticle enzyme immunoassay) at seven to nine months of age. RESULTS: The seroconversion rate of Hepatitis B after vaccination was 98.3%. There were no significant differences in positive rate of antibody according to gestational age, birth weight and sex. Seroconversion rate to hepatitis B in twins was lower than in singlets. Twenty-two infants among 23 infants, who were able to assess antibody titer, showed effective antibody titer, above 100mIU/ml. CONCLUSION: The results suggest that the simultaneous administration of hepatitis B vaccine with DPT/TOPV is very effective and simplifies schedule. Moreover, this schedule will improve the compliance of vaccination.

PURPOSE: Measles is one of the most highly communicable infectious disease, but has become a rare disease with the widespread use of vaccine. Recently, however, resurgence of the disease in school aged or adolescents who had received the vaccine before or at the 15 month warrants reappraisal of the efficacy of the vaccination. The purpose of this study was to investigate positive prevalence of antibody and its quantitative titers in different age groups in order to determine necessity and appropriate time of booster vaccine. METHODS: We measured measles antibody in the sera of 192 children from different age groups(61 cases from 4-6 years of age, 40 cases from 8-9 years of age, 47 cases from 12-13 years of age, 44 cases from 15-16 years of age). Eight to ten children from each group were selected and quantitative antibody titers were measured by EIA(measles Ig G EIA SEIKEN) method. RESULTS: 1) The positive prevalence of measles antibody in four to six year age group(72%) was significantly lower than the expected positive prevalence of measles antibody(95%) (p<0.001). 2) Median antibody titer in twelve to thirteen year age group tended to be relatively lower than the other age groups. 3) There was no significant differences in the positive prevalence of measles antibody and median titers between sex. CONCLUSIONS: This data supported that the booster vaccination be needed at four to six years of age.
