PURPOSE: The aim of this study was to evaluate the dietary behaviors of preschoolers in Daejeon using the Nutrition Quotient for Preschoolers (NQ-P). METHODS: The study subjects were recruited from child-care centers and kindergartens located in Daedeok-gu, Daejeon between August and September 2018. A total of 411 preschoolers aged 3 ~ 6 years were included in the data analyses. A questionnaire of NQ-P, which consisted of 14 checklist items on dietary behaviors, was completed by the parents or guardians of the study subjects. The NQ-P scores and its three factors, including “balance”, “moderation”, and “environment” factors, were calculated according to sex, age, and weight status. Differences in the NQ-P scores and their factors according to sex, age, and weight status were tested using a student's t-test. RESULTS: The mean NQ-P score of the total subjects was 58.5 ± 9.2, which was within the medium-low grade. The NQ-P score was 58.5 ± 9.4 in boys and 58.6 ± 9.0 in girls (p = 0.955). The NQ-P score was similar regardless of the age groups (57.8 ± 9.4 in 3 ~ 4 years vs. 59.2 ± 9.0 in 5 ~ 6 years, p = 0.124), whereas subjects aged 5 ~ 6 years showed a significantly higher scores of environment factors than those aged 3 ~ 4 years (67.9 ± 16.8 vs. 61.7 ± 17.3). The mean score of the moderation factor was lower in the overweight/obese children compared to the non-overweight/obese children (46.6 ± 13.3 vs. 51.0 ± 16.2, p = 0.012). Compared to children aged 3 ~ 4 years, children aged 5 ~ 6 years had higher intakes of vegetable dishes and processed meat. The overweight/obese group showed a higher consumption of processed beverages than the non-overweight/obese group. CONCLUSION: The current study indicates that the dietary behaviors of preschoolers residing in Daejeon need to be improved. These findings suggest that nutrition education or health interventions targeting young children is necessary for improving their nutritional health status.

Larval nematodes belonging to genera Ancylostoma, Strongyloides, Rhabditis, Gnathostoma or microfilariae (Onchocerca volvulus)/adult filaria (Loa loa) can invade human skin, each making different lesion. In a 71-year old immunocompetent Koreanman with 23% eosinophilia and elevated serum IgG (2530 mg/dl), a skin biopsy was undertaken for a nodular lesion at abdominal wall. A longitudinal section of a larval nematode was recognized in mid-dermal tunnel surrounded by pseudolymphomatous diffuse lymphoreticular cell infiltration. The larval nematode, 15 um in maximum diameter, had outermost cuticular layer and pale intestinal cells. The nematode section was identified as a filariform larva of Strongyloides stercoralis mainly based on its maximum diameter. In Korea, this is the first description of a cutaneous larval nematode infection. This case did not show quick migration of lesion which is a typical manifestation of classical cutaneous larva migrans.

OBJECTIVE: To investigate the association between endometriosis and polymorphisms of N-acetyl transferase 2 (NAT2), glutathione S-transferase M1 (GSTM1), and cytochrome P450 (CYP) 1A1 genes in Korean infertile patients. MATERIALS AND METHODS: A total of 303 infertile patients who had undertaken diagnostic laparoscopy during January, 2001 through December, 2003 at Samsung Cheil Hospital enrolled in this study. The patients were grouped according to laparoscopic findings: minimal to mild endometriosis (group I: n=147), moderate to severe endometriosis (group II: n=57), normal pelvic cavity (n=99). Peripheral blood was obtained and genomic DNA was extracted. The genotypes of each genes were analyzed using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). For NAT2, RFLP was used to detect the wild type (wt) and mutant (mt) alleles, enabling classification into slow (mt/mt) or fast (wt/wt or wt/mt) acetylation genotypes. For GSTM1, PCR was used to distinguish active (+/- or +/+) from null (-/-) genotypes. For CYP1A1, MspI digestion was used to detect the wild type (A1A1), heterozygote (A1A2) or mutant (A2A2) genotypes. RESULTS: The genotype frequencies of NAT2 slow acetylator was 12.8%, 10.9%, 12.8% in group I, group II and control, respectively. The genotype frequencies of GSTM1 null mutation was 55.3%, 41.8%, 53.2% in group I, group II and control, respectively. The genotype frequencies of CYP1A1 MspI polymorphism was 16.3%, 9.1%, 18.1% in group I, group II and control, respectively. No significant difference was observed between endometriosis and normal controls in the genotype frequencies of the NAT2, GSTM1, CYP1A1 MspI polymorphism. CONCLUSION: The NAT2, GSTM1, CYP1A1 gene polymorphism may not be associated with the susceptibility of endometriosis in Korean women.

Carcinosarcoma of the salivary gland is an extremely rare tumor that is composed of both malignant epithelial and mesenchymal components. Diagnosing carcinosarcoma with fine-needle aspiration cytology is challenging because of its overlapping cytomorphologic characteristics with other high-grade malignant salivary gland tumors. Among the many features, including pleomorphic oncocytoid epithelial components, necrotic background, and mitoses, recognizing the singly scattered atypical spindle cells is most essential in carcinosarcoma. We present a case of a 66-year-old male patient with characteristic features of carcinosarcoma, who was successfully treated by wide local excision and subsequent radiation therapy.

Acute generalized exanthematous pustulosis (AGEP) is characterized by acute nonfollicular sterile pustules on a background of edematous erythema. Hydroxychloroquine (HCQ), an antimalarial drug, widely used to treat rheumatic and dermatologic diseases. HCQ has been reported to be an uncommon cause of AGEP. We report a 60-year-old woman with rheumatoid arthritis requiring the use of HCQ presented fever and erythematous eruption on the trunk with sterile pustules. Leukocytosis and elevated erythrocyte sedimention rate noted on laboratory examination. On the histopathological examination of the skin biopsy specimen showed neutrophilic infiltration and scattered eosinohpils. The lesions were resolved with removal of HCQ. The clinical course was consistent with the diagnosis of AGEP associated with HCQ. We reported a case of typical AGEP associated with HCQ in a patient with Rheumatoid arthritis. The patient presented resolution from cutaneous lesions with withdrawal of culprit drug, without the need of systemic steroid.

OBJECTIVE: Embryonic stem (ES) cells could be differentiated into the specific cell types by alternation of culture condition and modification of gene expression. This study was performed to evaluate the differentiation protocol for mouse and human ES cells to insulin secreting cells. METHODS: Undifferentiated mouse (JH-1) and human (Miz-hES1) ES cells were cultured on STO feeder layer, and embryoid bodies (EBs) were formed by suspension culture. For the differentiation, EBs were cultured by sequential system with three stage protocol. The differentiating ES cells were collected and marker gene expressions were analyzed by semi-quantitative RT-PCR in each stage. Amount of secreted insulin levels in culture media of human ES cells were measured by human insulin specific RIA kit. RESULTS: During the differentiation process of human ES cells, GATA-4, alpha-fetoprotein, glucose transporter-2 and Ngn-3 expression were increased whereas Oct-4 was decreased progressively. Insulin and albumin mRNAs were expressed from stage II in mouse ES cells and from stage III in human ES cells. We detected 3.0~7.9 microU/ml secretion of insulin from differentiated human ES cells by in vitro culture for 36 days. CONCLUSION: The sequential culture system could induce the differentiation of mouse and human ES cells into insulin secreting cells. This is the first report of differentiation of human ES cells into insulin secreting cells by in vitro culture with serum and insulin free medium.

OBJECTIVE: This study was designed to investigate the efficacy in the combination of haloperidol and clonidine with chronic schizophrenia. Moreover, we evaluated the effects of clonidine to the plasma haolperidol and reduced haloperidol concentration 36 patiens were entered on 4 weeks by the double blind trial. METHOD: The patients (male=11, female=25) were randomly divided into two groups of eighteen patients each. Their antipsychotic medication was fixed for 2 weeks before double blind trial with haloperidol and clonidine or placebo. Clonidine was started at 0.15 mg/day and then raised 0.6mg/day during 4 days, and the placebo was applied by same method as clonidine. The clinical assessment of the patients was assessed with BPRS and NOSIE. The plasma concentrations of haloperidol and reduced haloperidol were measured by HPLC (UV detector). RESULTS: 1) There were no statistical differences in sex distribution, age, duration of illness, dosages of haloperidol, plasma concentration of haloperidol and reduced haloperidol of each groups before clonidine or placebo trial. 2) On total and subcluster scores of BPRS and total score of NOSIE, there were decreased tendencies over the time, but there was no statistical significance in both groups. 3) Plasma concentrations of haloperidol and reduced haloperidol after 4 weeks of clonidine trial were revealed statistically significant increasement as compared to baseline. CONCLUSION: The combination of haloperidol and clonidine for 4 weeks did not reveal the improvement. In our opinions the reasons of those results were that our samples were not made of paranoid type of schizophrenia, the duration of clonidine trial was not good enough. So we should suggest that more specifying design will be needed.

PURPOSE: The relationship between menopausal status at diagnosis and the prognosis in breast carcinoma remains uncertain. However, it is widely considered that breast cancer in young women is more lethal than in older patients. We therefore attempted to determine whether menopausal status could be a useful prognostic factor for breast cancer. METHODS: A retrospective study was conducted of premenopausal women who had undergone a definite operation between Jan. 1997 and Dec. 1998 in the Department of Surgery, Samsung Medical Center. Clinical features, histopathologic findings, and prognostic factors were evaluated and compared with those for the equivalent surgical group of postmenopausal women. RESULTS: There were 207 cases (86.3%) of infiltrating ductal carcinomas, 10 (4.2%) of infiltrating lobular carcinomas, 6 (2.5%) of ductal carcinomas in situ, and 16 (6.7%) of special type cancers which showed good prognosis. There were some differences in these incidences from those of the postmenopausal women, but they were not statistically significant (P>0.05). Tumor size and lymph nodal status showed no difference between the two groups (P=0.288), nor were there any significant differences in terms of TNM stage, ER/PR status, nuclear or histologic grade (P>0.05). CONCLUSION: There were little differences in pathologic and prognostic factors between premenopausal and postme no-pausal breast cancer patients. Premenopausal status and young age did not have poorer prognostic factors and were predicted to have not worse prognosis.
