PURPOSE: To differentiate mature and immature ovarian teratomas, using CT findings. MATERIALS AND METHODS: The CT findings of ten mature ovarian teratomas (in one patient, bilateral) and ten which were immature were compared, using statistical analysis. images were evaluated for size, margins, architecture, contents (muralnodules, fat, calcification), septa, local invasion and distant metastasis. These findings were compared with pathologic findings. RESULTS: Of the ten mature tumors, nine were well defined and predominantly cystic ininternal architecture, and one was mixed. Mural nodules were found in six tumors, fat in all, distinct calcification in seven, and regular septa in three lesions. Of the ten immature tumors, eight had irregular margins, Seven were predominantly solid in internal architecture and irregularly enhanced, two were mixed, and one was mainly cystic. Fat was detected in five lesions, indistinct scattered calcification in six, irregular septa in three, and local invasion or distant metastasis in four patients. CONCLUSION: Compared with mature ovarianteratomas, those that are immature tend to show CT findings of marginal irregularity, solid mass with irregular enhancement, scattered indistinct calcifications, septal irregularity, local in vasion or distant metastasis. Our experience suggests that these findings may be helpful in differentiation of mature and immature ovarianteratomas.

The purpose of this study was to examine the influence of maternal socioeconomic status, maternal oral health behaviors, and oral health behaviors of children, on the prevalence of early childhood caries in children aged 5 years. The Korean National Health and Nutrition Examination Survey data collected between 2007 and 2014 were applied to this study, and the study sample included 824 children who received oral examinations and participated in the health behavior survey. The factor that affected the prevalence of early childhood caries were confirmed by maternal and child factors. The data were analyzed using multiple linear regression. The mothers' age, income level, and job status affected the prevalence of early childhood caries. There was a significant difference in the analysis considering the factors of motherhood and children in the prevalence of early childhood caries according to mother's age, education level, income level, and the child's oral examination. The prevalence of early childhood caries was higher in children who received oral examinations than in those who did not. When the mother's educational level was higher than college education, it was found that the index of child, i.e., there was a difference in the prevalence of early childhood caries according to the mother's educational and income levels. These results indicate that maternal socioeconomic characteristics are correlated with the oral health of children. Therefore, oral health education programs that include mothers for the prevention of early dental caries in children may improve the dental health of children. In addition, specific oral health policies are necessary to address the differences in the oral health between the income groups.

BACKGROUND: The prevalence of dementia is estimated to be as high as 11.3% among coummunity-dwelling persons over 65 years of age in Korea. The fear of dementia for both patients and families is growing because of the chronicity and progressiveness of the disease. Though the recognition, evaluation, and management of patients with dementia are important for the care of older pateint, unfortunately, MMSE takes 5 to 10 minutes to administer and is cumbersome to carry for all elderly patients in busy office. The Clock Drawing Test has been known as valid, easily administered and low cost screening procedure for the congnitive impaiment associated with dementia in general geriatric clinic population. In this study, we assessed the usefulness of this measure as a screening test for dementia, on the basis of the correlation between clock drawing and MMSE-K. METHODS: The subjects for this study consisted of 47 elderly who visited to two elderly clubs in Seoul from April 1996 through June 1996 or the outpatient department of Family medicine of the Ehwa Mok-dong hospital. They received the Mini-Mental Status Exam and the Clock Drawing test. Three observers evaluated them by ratings from 10(best) to 1(worst). Inter-rater reliability of scores from the Clock Drawing Test was assessed and Pearson correlation coefficients were used to examine the relationships between scores from the Clock Drawing Test and MMSE-K. RESULTS: Their mean age was 75.4 years with range of 65 to 91 years. There were 34 women and 13 men. Correlations between individual raters was highly significant(y=0.8939, 0.8552, and 0.8698, respectively ; P<0.01). Compared to scores on MMSE-K, rating from clock drawings by each of 3 raters revealed statistically significant correlations(y=0.7164, 0.7398, and 0.6884, respectively ; P<0.01). CONCLUSIONS: The clock drawings can be rated reliably by even untrained observers and performance on this task relates significantly to performance on MMSE-K of severity. We confirmed the usefulness of clock drawings as a simple, easily administered, low cost, and reliable general screening tool for dementia in a general geriatric clinic population.

PURPOSE: To measure the mean size of the various portions of the corpus callosum in normal Korean children, using MR imaging. MATERIALS AND METHODS: Our subjects were 166 children (male : female=100 : 66) aged under 15 whose findings on MR imaging and neurologic examination were normal. Using midsagittal T1-weighted imaging, we measured the length of the brain and corpus callosum, the height of the latter, and the thickness of its genu, body, transitional zone and splenium. The measurements were statistically analysed according to age and sex. RESULTS: Brain length and the size of the various portions of the corpus callosum tended to increase relatively rapidly during the first three years of life, but the rate of growth tended to decrease according to age. The mean length of the brain and corpus callosum and the mean thickness of the splenium of the corpus callosum did not differ according to sex. The mean thickness of the genu, body and transitional zone of the corpus callosum was greater in males than in females. The ratio of the length of the corpus callosum to the anteroposterior diameter of the brain was significantly greater in females than in males (alpha = 0.05). CONCLUSION: Using MR imaging, we measured the mean sizes of the various portions of the corpus callosum in normal children ; these values may provide a useful basis for determing changes occurring in its structure.

OBJECTIVES: This study was intended to compare psychiatric symptoms, neurocognitive function and quality of life between normal finding group and abnormal finding group on Brain-MRI. We investigated which variables were related to quality of life (QOL) in traumatic brain injury (TBI) patients. METHODS: Among thirty nine patients who had mild to moderate TBI, twenty two patients (57%) showed abnormal brain MRI findings correlated with their injury and 17 patients (43%) showed normal or nonspecific brain MRI findings. All patients completed Symptom check list-90-revised (SCL-90-R), Beck depression inventory (BDI), State-trait anxiety inventory (STAI), Korean version of the Smith Kline Beecham Quality of Life scale (KvSBQOL) and Marlowe-Crown Social Desirability Scale (MCSDS). Two psychiatrists assessed the patients using Hamilton rating scale for depression (HAMD), Hamilton anxiety scale (HAMA) and Functional assessment scale (FAS). In addition, Korean Wechsler Adult intelligence Scale (K-WAIS), Rey-Kim Memory Test (R-KMT) and Kims frontal-executive neuropsychological test (KF-ENT) were assessed. RESULTS: On FAS, the mean score was significantly lower in the abnormal finding on B-MRI group than the normal finding group (p=0.014). In the patients with abnormal MRI findings, the QOL scores significantly correlated with several subscales of SCL-90-R (obsessive-compulsive, depression, anxiety, global severity index and positive symptom total), FAS and memory quotient after controlling for MCSDS. However, in the patients with normal MRI findings, QOL scores significantly correlated with BDI and all subscales of SCL-90-R. When all pertinent variables were entered in stepwise regression analysis, depression (p<0.05) and interpersonal sensitivity (p<0.05) subscales of SCL-90-R explained 38.5% and 17.7% of the variance of the QOL score in patients with abnormal MRI findings. As for the patients with normal MRI findings, depression (p<0.05) subscale of SCL-90-R accounted for 54.2% of the variance of the QOL score. CONCLUSION: TBI patients who have persisting abnormal brain findings suffered from impaired daily functioning. Depression and interpersonal sensitivity explained 55% of the variance of the QOL together. In the patients with normal brain MRI findings, objective depression or anxiety did not correlate with QOL whereas subjective depressive symptom accounted for 54.2% of the variance of the QOL. This study suggests that subjective psychiatric symptoms including depression significantly correlated with the subjective QOL of TBI patients regardless of their brain MRI finding.

Hepatie hilar ductal carcinoma is relatively rare, but the prognosis is known to be poor because an early diagnosis is difficult. Because the majority of patients are already infiltrated into adjacent organ by itself at the diagnosis, the rate of resectability is low. The best method of treatment is curative resection, and the range of tumor invasion is very important. The preoperative diagnosis is difficult because the cholangiography may be normal in cases of superficial invasion. Multifocal lesions within the biliary tract may be identified in as many as 10 percent of patients, Especially, the papillary type has the best prognosis and is associated with multiple tumors within the bile duct. We report a case that percutaneous transhepatic cholangiogram showed normal distal common bile duct, but the hepatic hilar confluence and ampulla of Vater lesion was confirmed as adenocarcinoma.

OBJECTIVES: Schizophrenia, one of the major mental illnesses, shows abnormal developmental patterns such as delayed developmental milestones, impaired language and motor function, and poor premorbid social adjustment long before the onset of clinical symptoms of illness. In this study, we tried to find out developmental patterns and premorbid adjustment during childhood and adolescence in Schizophrenic patients. METHODS: The subjects were 56 inpatients (26 male patients and 30 female patients) who met the diagnostic criteria for schizophrenia by DSM-IV and 52 healthy control subjects (25 male patients and 26 female patients). Interview with subjects and their families and the review of medical records were done to assess sociodemographic factors, timing of developmental milestones, language and motor function of childhood, and timing of sexual maturational events. Obstetrical Complication Scale of Lewis was used to get information on the subjects' prenatal and perinatal history, and Premorbid Social Adjustment Scale (PSAS) to assess premorbid adjustment. RESULTS: 1) There were no significant differences in the rates of obstetrical complications. The deveolpmental milestones during infancy such as sitting, walking, age of first sentence were significantly delayed in the Schizophrenics than in the controls (p<0.05). 2) Disturbances of speech and language development were significantly more common in the schizophrenics than in the controls (p<0.05), but there were no significant differences in the rates of disturbance in motor development. Mean ages of reading and writing were significantly delayed in schizophrenics than in the controls (p<0.05). No significant differences were found between males and females for either language disturbance or motor disturbance in the Schizophrenics. 3) During adolescence, premorbid adjustment was poorer in Schizophrenic patients (p<0.05). The Schizophrenic patients scored significantly worse than the controls on both sociability and schooling domains (p<0.05). There was a trend for correlation between poor premorbid functioning and early age of onset, but it failed to achieve statistical significance (Spearman's coeff =-0.27, p=.07). 4) Male Schizophrenic subjects showed poorer premorbid functioning on schooling domain than female Schizophrenic subjects (p<0.05). No significant difference was recogni ed in timing of sexual maturational events between Schizophrenics and controls. CONCLUSION: In summary, the Schizophrenics were significantly delayed in infantile developmental milestones, impaired in development of language, delayed mean age of reading and writing, and showed poorer premorbid social adjustment than the controls.
