Objective : This research was carried out to find out the general understanding of allergic diseases, the frequencies of allergic diseases and the attitude toward their oriental medical treatment(OMT) among common people. Methods : A total of 360 visitors at The 2nd International Exhibition on Oriental Medicine in 2000, participated in this research. We performed this survey with 22 items on the questionnaire. Results : Respondents knew the. fact that the allergic diseases were hereditary and could be affected by the living environment. 41.8% of the respondents had a past history of allergic diseases. Among the people who had allergic diseases, 63.5% had allergic rhinitis, which was the largest portion. Among them, 52.9% had a familial history. 81.5% of respondents with allergic diseases received western medical treatment for their allergies, 16.3% received both western and oriental medical treatment and 2.2% received OMT only. Among those who were treated for allergic disease, 62.0% were unsatisfied with the low effect of the treatment. To the point of excellence of OMT, 69.7%, which was the largest portion of respondents, believed that OMT could improve their constitutions. The problem with OMT was the high price of herbal medicine and this was the problem most frequently stated, by 51.4% of respondents. There was a positive attitude towards the effect of OMT, and respondents had a preference to receive OMT in the future(p<0.01). Conclusions : These days, it is a fact that the OMT for allergic diseases has a lower proportion to that of western treatment In order to increase the role of OMT, we think, oriental medical doctors need to develop an explanatory model of improving $people^{\circ}{\phi}s$ constitutions and should lower the cost of herbal medicine.

Objectives : Polymorphisms of genes from glutathione Stransferases (GSTs) and N-acetyltransferase 2 (NAT2) have been associated with increased susceptibility to various cancers. Previous results showed that East Asians such as Koreans, Japanese and Chinese have a much higher frequency of the GSTM1 and GSTT1 null genotypes and NAT2 rapid acetylator type. Therefore, we investigated the association between the polymorphic types of GSTs (GSTM1, GSTT1, GSTP1) and NAT2 and the incidence of gastric cancer which is one of the most prevalent cancers among the East Asians. Methods : It was performed in a case-control study consisting of 238 healthy subjects and 108 cancer patients (54 distal and 54 proximal carcinomas). We also evaluated the association between GSTs and NAT2 and the risk factors for gastric cancer such as alcohol consumption, smoking, H. pylori infection, family history of gastric cancer, and tumor location. Results : In our study, the percentage of cases whose hometown was rural was higher than those of controls (odds ratio (OR) =2.88; 95% CI=1.72-4.76), and the frequency of the lower socio-economic status increased significantly in patients (OR=2.53; 95% CI=1.59-4.02). There was no significant difference in the GST polymorphic types between the cases and controls. However, NAT2 rapid or intermediate acetylator types were frequently detected in the cases with family history of gastric cancer (OR=1.92; 95% CI=1.79-26.0). Conclusions : These results suggest that the hometown and socio-economic status are important environmental factors for gastric carcinogenesis, and NAT2 polymorphic types could be associated with familial gastric carcinoma.

Background: Pulmonary paragonimiasis is caused by consumption of raw or improperly cooked crabs infected by a laval stage (metacercaris) of the parasite. In our country it had been a highly prevalent endemic disease until th late 1960s, and after then it's prevalence has been markedly decreased. But because some people have continued to ingest undercooked crabs, this disease have yet occured sporadically. Methods: We reviewed the clinical and radiological findings retrospectively in seventy-four patients of pulmonary paragonimiasis including familial infestation in 7 familes (20 cases) who were confirmed by food history, clinical and radiological findings, and labaratory data. Results: The male: female ratio was 2.2:1 and most prevalent age was 40-49 years old. Twen6ty nine patients (39%) had ova-positive infection. The detection sites were sputum (48%), pleural fluid (17%), fine needle aspiration biopsy of nodular or cystic lesion (17%), pleural biopsy (7%), skin nodule biopsy (7%), and stool (3%). The patients had pulmonary symptoms in 63 cases (85%) but 9 cases did not have any symptoms. The 53 cases (72%) had abnormal radiological findings in lung parenchyme (75%) and pleura (63%). However 21 cases (28%) showed no specific findings in their chest X-ray. Serum titers (ELISA) of specific IgG for paragonimiasis in 13 cases were followed for average 9.8 months after treatment, which showed slow decreasement. In the evaluation of family member (7 family, 20 cases), all members having the common dietary history together with a proven patients were confirmed this disease by serological test, regardless of the presence or the abscence of clinical or radilogical symptoms. Conclusion: We evaluated the clinical and radiological findings in 74 cases of pulmonary paragonimiasis including 7 family members who had a history of ingestion of improperly cooked crabs together with patients. The paients of pulmonary paragonimiasis have various findings in clinical and radiological findings. Common diet exposure history and laboratory findings including specific IgG were important in earlier diagnosing and treating in family members of patients.

Purpose: Colonic polyposis is less common in children than in adults. The clinical data pertaining to colonic polyposis in children are limited. Children with colonic polyposis have complications associated with numerous polyps, malignant transformation of the polyps, and extraintestinal neoplasms. We studied the clinical spectrum, endoscopic characteristics, and histologic findings of colonic polyposis in Korean children. Methods: We reviewed the clinical data of 37 children with multiple colonic polyps between 1987 and 2009. The mean age at the time of diagnosis of colonic polyposis was 8.0${\pm}$3.2 years. Results: Peutz-Jeghers syndrome, juvenile polyposis syndrome, familial adenomatous polyposis (FAP), and lymphoid polyposis was diagnosed in 22, 7, 6, and 2 children, respectively. The most common clinical presentation in children with colonic polyposis was hematochezia. A family history of colonic polyposis was noted in 7 children. The colonoscopic findings of colonic polyposis varied with the size and number of polyps. The majority of polyps were multi-lobulatd and pedunculated in children with Peutz-Jeghers syndrome. The polyps in children with juvenile polyposis syndrome were primarily round and pedunculated. For the children with FAP, the colon was carpeted with small, sessile polyps. There were multiple sessile polyps in the patients with lymphoid polyposis. Surgical polypectomy was performed in 14 children (38%). Intestinal segmental resection was performed in 13 children (35%). Four patients with FAP underwent total colectomy. Four children with Peutz-Jeghers syndrome had extraintestinal neoplasms. No malignant transformation of polyp was identified. Conclusion: Children with colonic polyposis should undergo a careful initial evaluation and require periodic re-evaluation.

Purpose: This study was to investigate the clinical manifestations of FTT in children. Methods: From March 1997 to July 1999, clinical observations were made on patients with FTT who had visited to Samsung Medical Center. Detailed histories and through physical examinations were taken, and when suspected organic FTT, basic laboratory studies were done. Results: Upon the review of medical records, we investigated the clinical manifestations of 74 children, aged 1 month and 13 year 1 month. The causes of FTT were composed of either physiologic (47.8%) or pathologic (52.2%) ones. Among the physiologic FTT, were there familial short stature (FSS, 14.5%), intrauterine growth retardation (IUGR, 14.5%), constitutional growth delay (CGD, 11.6%), idiosyncrasy and prematurity. Among pathologic causes, neurologic disorders (20%) are the most common causes of FTT, and then follow by GI (13.4%), allergic and infectious disorders in decreasing order. The data showed that average caloric intake in patients with FTT was 76,2% of recommended amount. FTT patients with CGD, IUGR, and idiosyncrasy had tendency to take small foods. The FTT children with prematurity, IUGR and pathologic FTT, were short and thin for their ages. However FTT children with CGD and FSS had tendency to be thin with relatively normal heights for their ages, in comparison with those of the children with prematurity, IUGR and pathologic FTT. Conclusion: The diagnosis of FTT was easily obtained with simple and through medical history, physical examination, and minimal laboratory tests. In this study, organic FTT was more prevalent than physiologic one. This results indicate that early intervention is mandatory, because children may develop significant long-term sequelae from nutritional deficiency.

Puruose : Thin glomerular basement membrane disease(TGBMD) is found in patients with family history of hematuria. TGBMD is autosomal dominant and is known to be one of the commonest causes of asymptomatic hematuria. This study was conducted to evaluate the histological and clinical features of patients with TGBMD. Methods : 150 cases diagnosed with TGBMD by renal biopsy while admitted in the department of pediatrics, Kyungpook National University Hospital between January 1999 and December 2003 comprised the study group. The following parameters were retrospectively anaIyzed age of onset, hematuria pattern, existence of proteinuria, process of diagnosis, laboratory findings, thickness and character of basement membrane and family history. Results : The mean age at the time of diagnosis was 7.9 years. The male to female ratio was 65:77. 94 patients or 66% visited the hospital with a chief complaint of persistent microscopic hematuria. Gross hematuria accounted for 13 cases or 9%. 78 cases(55%) were found to have hematuria for the first time from a routine school urinalysis screening. The renal biopsy showed the thickness of basement membrane to be 186$\pm$36 nm. Focal lamellation of the basement membrane was found in eight cases. In the family history, hematuria was shown in 10 cases on the Paternal side, 13 on The maternal side and none on both sides. In seven cases, hematuria was shown among siblings. No significant differences were found among the laboratory test results which were conducted at an average interval of fifteen months. Conclusion : TGBMD is one of the major causes of asymptomatic hematuria in children, which was diagnosed in increasing numbers since school urinary mass screening test started in 1998. In cases with familial progressive renal disease or focal duplication in the basement membrane Alport syndrome should be considered.

Purpose : It is known that 3-50 percent of type 1 diabetes mellitus(T1DM) patients develop autoimmune thyroid disease. We analyzed the clinical characteristics of autoimmune thyroid disease(AITD) developed in patients with T1DM in Korean. Methods : The medical records of 139 patients, who were followed up in Department of Pediatrics, Seoul National University Children's Hospital from Jan. 1981 to Jul. 2004, were analyzed retrospectively. Results : Forty-four males and 95 females were enrolled. At least one of the autoantibodies for thyroid was positive in 54 cases. The detection rate for AITD was not correlated with sex ratio, control of T1DM, body mass index, age at diagnosis of T1DM, and familial history of thyroid disease, between two groups. In the male group, AITD was more frequently found at a younger age than in the female group. The frequency of AITD was significantly higher in the goiter group without sex differences. In the thyroid disease group, 40 patients(74.0 percent) were euthyroid, seven patients(12.9 percent) were hypothyroid, and seven patients(12.9 percent) were hyperthyroid. Conclusion : We should monitor thyroid function and autoantibodies routinely in T1DM patients who develop goiters, or young boys with T1DM.

Background: Cigarette smoking and tobacco chewing are common modes of consuming tobacco all over the world. Parents need to be aware that germ cell integrity is vital for birth of healthy offspring as biological parenting begins much before birth of a child and even before conception. The present study was conducted to determine the etiology of non-familial sporadic heritable retinoblastoma (NFSHRb), by evaluating oxidative sperm DNA damage in fathers due to use of tobacco (smoking and chewing). Materials and Methods: We recruited 145 fathers of NFSHRb children and 53 fathers of healthy children (controls) in the study. Tobacco history was obtained by personal interview. Seminal reactive oxygen species (ROS) in semen, sperm DNA fragmentation index (DFI) and 8 hydroxy 2' deoxyguanosine (8-OHdG) levels in sperm were evaluated. The RB1 gene was screened in genomic blood DNA of parents of children with NFSHRb and controls. Odds ratios (ORs) derived from conditional logistic regression models. Results: There was significant difference in the levels of ROS (p<0.05), DFI (p<0.05) and 8-OHdG (p<0.05) between tobacco users and non-users. The OR of NFSHRb for smokers was 7.29 (95%CI 2.9-34.5, p<0.01), for tobacco chewers 4.75 (2.07-10.9, p<0.05) and for both 9.11 (3.79-39.2; p<0.01). Conclusions: This study emphasizes the adverse effect of tobacco on the paternal genome and how accumulation of oxidative damage in sperm DNA may contribute to the etiology of NFSHRb. In an ongoing parallel study in our laboratory, 11 of fathers who smoked underwent. Meditation and yoga interventions, showed significant decline in levels of highly mutagenic oxidised DNA adducts after 6 months. Thus our lifestyle and social habits impact sperm DNA integrity and simple interventions like yoga and meditation are therapeutic for oxidative damage to sperm DNA.

Objectives：The major goal of this study was to investigate the treatment outcome of psychiatric treatment in inpatients with conduct disorder and to elucidate factors affecting its prognosis. Methods：We reviewed the medical records of 300 inpatients with conduct disorder who had been treated with a specialized adolescent treatment program. Follow-up structured telephone interview had been performed in 96 patients. Results：1) At the point of follow-up, 90% of the patients were improved in behavioral patterns, 2% of the patients were worse, and 8% of the patients were unchanged. 2) Intrafamilial relationship was improved in 70% of the patients, worse in 2%, and unchanged in 28%. 3) Fifty-seven percent of families thought to be helped by psychiatric inpatient treatment, 6% replied to be harmed, and 37% thought not to be helpful. 4) Comparing the good prognosis group who were all better in behavioral patterns, intrafamilial relationship, and efficacy of treatment with the rest of subjects, the good prognosis group was significantly younger and had more history of problems in familial structure. Conclusion：Although the present study had some meterological limits, the promising positive results in the outcome of inpatients with conduct disorder encourages further more sophisticated investigations in this problematic psychiatric conditions.

Hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome is a rare autosomal recessive urea cycle disorder. HHH is caused by a deficiency of the mitochondrial ornithine transporter protein, which is encoded by the solute carrier family 25, member 15 (SLC25A15) gene. Recently, government supported Korean newborn screening has been expanded to include a tandem mass spectrometry (MS/MS) measurement of ornithine level. We report a case of a neonate with HHH syndrome showing a normal MS/MS measurement of ornithine level. A female newborn was admitted to neonatal intensive unit due to familial history of HHH syndrome. Her parents were consanguineous Parkistani couple. The subject's older sister was diagnosed with HHH syndrome at age of 30 months based on altered mental status and liver dysfunction. Even though the subject displayed normal ammonia and ornithine levels based on MS/MS analysis, a molecular test confirmed the diagnosis of HHH syndrome. At 1 month of age, amino acid analysis of blood and urine showed high levels of ornithine and homocitrulline. After 11 months of follow up, she showed normal growth and development, whereas affected sister showed progressive cognitive impairment despite no further hyperammonemia after protein restriction and standard therapy. Our report is in agreement with a previous Canadian study, which showed that neonatal samples from HHH syndrome patients demonstrate normal ornithine levels despite having known mutations. Considering the delayed rise of ornithine in affected patients, genetic testing, and repetitive metabolic testing is needed to prevent patient loss in high risk patients.
