OBJECTIVES: This review strives to look through the reality of school situation in Korea which gives the most severe burden of conflict to adolescents nowadays, for the purpose of better understanding of them. METHODS: Followings comprised of the summary of the materials from the published articles and books, and from mass media regarding 'school collapse' phenomenon in Korea, and also include materials regarding school non-attenders. And discussion was done with developmental and psychiatric perspectives on the phenomenon along with on school non-attenders. CONCLUSION: School non-attenders nowadays with the issue of 'school collapse' have different characteristics from the dropouts reported in many previous studies. Psychiatrists need to accommodate their previous view on adolescents as the way of adolescents' coping has rapidly changed. It is noted that there are few researches regarding school non-attenders, as well as regarding school factors associated with non-attending in Korea. This review was done to call for future studies focused on the interdependent relationship between school processes and the individual characteristics of non-attenders, so that enable us to capture the complexity of how adolescents make their decision of hangingin or droppingout of school.

BACKGROUND: Clonorchiasis is a trematodiasis caused by chronic infestation of liver flukes, Clonorchis sinensis(CS). We usually diagnosed clonorchiasis with stool examination. Intradermal(ID) test and radiologic findings have been also used for diagnosis. However, studies associated with ID test were very rare. So, we evaluated the stool examination and ID tests for CS detection associated with radiologic findings. METHODS: We analyzed 69 cases of patients requested stool parasite examination and ID test concurrently. For stool parasite examination, formalin ether precipitation method was used. Abdominal US and/or CT were also reviewed. Eosinophil counts and liver function test(LFT) were evaluated. Clinical diagnosis were reviewed retrospectively. RESULTS: Sensitivity and specificity of ID CS test were 63% and 71.4% respectively. Positive and negative predictive values were 58.6% and 75.0% respectively. US/CT findings showed 10% sensitivity and 52.9% specificity. Positive and negative predictive values of US/CT were 11.1% and 50% respectively. Paragonimiasis westermani ID test showed 17.2% positivity in CS ID test positive cases. No statistical differences were observed among groups in eosinophil and LFT results. Hepatobiliary diseases were the main clinical impression in CS ID test positive groups. CONCLUSION: For the diagnosis of clonorchiasis, stool examination was the most effective method. ID test and radiologic examination still have some limitations in diagnosis because of cured past infestation, small number of parasitic infestation or irreversible anatomical changes etc. However, ID test could have a better supplementary role for diagnosis of clonorchiasis rather than US/CT.

PURPOSE:Hypochondroplasia is a skeletal dysplasia characterized by poor childhood growth and an inadequate pubertal growth spurt. Final height attainment of hypochondroplasia has been reported to range between 120 and 152cm. Increased availability of growth hormone with the introduction of recombinant human growth hormone has allowed for clinical trials in a number of growth hormone sufficient children with growth problems. The purpose of this study was to assess the growth promoting effect of human growth hormone in children with hypochondroplasia. METHODS:Five patients with hypochondroplasia diagnosed by clinical and radiological findings between 1993 and 1997 at our hospital was aged 3 and 1/2 -11 and 1/2 years. Each patients continuously received human growth hormone 0.6-0.7U/Kg/week, intramuscularly or subcutaneously in 6-7 divided dose for 2 years. Standard auxologic assessment was carried out every 3 month interval in the first year after commencement of therapy and then same assessment was 6 monthly. Bone age was assessed 6 monthly using Gleurich-Pyle method. RESULTS:Mean height velocity of pretreatment and year 1 and 2 of GH treatment were 3.9+/-0.7, 6.5+/-1.8 and 5.7+/-1.5cm/year, respectively. Mean height standard deviation score for chronological age of pretreatment and year 1 and 2 of GH treatment were -2.7+/-0.3, -2.4+/-0.3 and -2.2+/-0.4, respectively. The increase in the height velocity diminishes over the subsequent year. The increment of bone age after GH treatment were same as the increments of chronological age. CONCLUSION: Short-term GH therapy increases the height velocity of children with hypochondroplasia, but the effect of GH therapy on final height remains unknown.

OBJECTS: Event related potential(ERF) has been recently applied to examine the neurophysiological disturbance in attention deficit hyperactivity disorder(ADHD), particularly with regard to N100 and P300 which are known as one of ERP components closely linked with cognitive function. On the basis of these aspects, this study was designed to evaluate electrophysiologic characteristics and its availability for diagnosis and treatment of ADHD children by comparison of ERP between normal controls and ADHD children before and after methylphenidate (MFD) administration. METHODS: We examined the topographic auditory ERF and T.O.V.A.(Test of variables of attention), a standardized computerized visual continuous performance test following administration of stimulant drug, MPD 10mg in 13 ADHD children and compared these results with those of 11 normal controls. RESULTS: The results were as follows: 1) Thought the difference was not spastically significant(P=0.0548), N100 latencies seemed to be longer in ADHD children than in normal controls. N100 amplitudes also seemed to be larger in ADHD children than in normal controls(P=0.0629). 2) The F300 latencies significantly shortened after MFD administration when compared with those before MPD administration in ADHD group(P<0.01). 3) ADHD group performed significantly less well than normal controls in T.O.V.A.(P<0.05). And T.O.V.A. scores significantly improved after MFD administration in ADHD group(P<0.01). 4) The N100 and P300 latencies and the T.O.V.A. scores were significantly correlated before MPD administration in ADHD group(P<0.05). 5) The F300 latencies before MFD administration were significantly correlated with the amplitudes of changes of T.O.V.A. scores after MFD administration(P<0.05). CONCLUSION: It seems that prolonged N100 latency of ADHD children can be regarded as a relatively enduring trait marker and that F300 latency may reflect attentional response ability along with therapeutic effect by stimulant.

OBJECTIVES: The purposes of this study were to develop the Korean version of Wahler Physical Symptom Inventory (WPSI), to examine the reliability and validity of it, and to investigate usefulness for diagnosing somatization. METHODS: The normal group was composed of 242 persons consist of middle and high school students, university students, and adults living in Seoul, Puchon, and Suwon. The two clinical groups consisted of 33 persons with somatic symptoms and 38 diabetic patients. RESULTS: Internal consistency (Cronbach alpha=.91) was very high. Test-retest reliability was calculated from 46 university group, and it's correlations was also high (.87). And the total score of K-WPSI was significantly and positively correlated with subscales of SCL-90-R. There was significant difference between the normal, psychiatry group, and diabetic group of K-WPSI (F=15.48, p<.001). Especially, K-WPSI was very useful to differentiate between the somatization group and diabetic group. CONCLUSION: K-WPSI was found to be a reliable and valid instrument for diagnosing somatization, and for differentiating somatization and diabetic groups. K-WPSI is a brief and economical questionnaire, which may curtail medical expenses of patients. It is also expectated that K-WPSI can be used for identifying somatization and providing information which may contribute to ascertain diagnosis. The limitation of this study is the small normative data, and not distinguishing sex differences. This limitation should be supplemented by future studies.
