Background: Among gliomas, the most common primary malignant brain tumor, incidental gliomasaccount for 2.5%–5% of cases. The controversy over whether to pursue immediate treatment or adopt a wait-and-see approach remains, and more molecular and immunological evidence is needed for definitive treatment decisions. Methods: Total RNA sequencing (RNA-seq) data and single cell RNA sequencing (scRNA-seq)data were retrospectively analyzed to compare the molecular and immunological tumor microenvironment differences between incidental glioma and symptomatic glioma samples. These were classified using symptom data from The Cancer Genome Atlas (TCGA) and public dataset. Results: RNA-seq analysis of the GBMLGG dataset identified 343 genes upregulated in symp-tomatic glioma and 118 in incidental glioma, with 104 common genes upregulated in symptomatic glioma across both the TCGA and Chinese Glioma Genome Atlas (CGGA) datasets. Enrichment analysis revealed that these 104 genes in symptomatic glioma were significantly associated with immunological pathways. scRNA-seq analysis of glioma revealed 11 cell types, including T cells, myeloid cells, and oligodendrocytes, with the tumor necrosis factor (TNF) signaling pathway strongly influencing other cell types, particularly myeloid cells. Enrichment and survival analyses showed that TNF signaling is associated with temozolomide resistance and poorer prognosis in glioma patients. Conclusion The findings suggest that symptomatic glioma enhances inflammatory responseslinked to poor prognosis and chemoresistance. This supports the hypothesis that immediate treatment of incidental glioma may improve patient outcomes over a wait-and-see approach.

Background: Inflammasomes are key in the initiation of inflammatory responses and serve to de-fend the organism. However, when the immune system is imbalanced, these complexes contribute to tumor progression. The purpose of this study was to investigate the effect of non-canonical inflammasomes on glioma malignancy. Methods: We performed bioinformatics analysis to confirm the expression of canonical andnon-canonical inflammasome-related molecules according to the degree of malignancy through immunohistochemical examination of glioma tissues obtained with patient consent from our institution. Results: Bioinformatics analysis confirmed that the expression levels of non-canonical inflam-masome-related molecules were significantly higher in tumor tissues than in normal tissues, and they also increased according to malignancy, which adversely affected the survival rate. Furthermore, in gliomas, positive correlations were found between N-form gasdermin-D, a key molecule associated with the non-canonical inflammasome, and other related molecules, including NLRP3, caspase-1, caspase-4, and caspase-5. These results were verified by immunohistochemical examination of glioma tissues, and the expression levels of these molecules also increased significantly with increasing grade.In addition, the features of pyroptosis were confirmed. Conclusion This study identified the potential of non-canonical inflammasomes as aggressiveness markers for gliomas and presented a perspective for improving glioma treatment.

Priapism is an abnormal persistent penile erection that continues for more than 4 hours, without sexual stimulation according to the definition of the AUA (American Urological Association) guideline on the management of priapism. It was relatively rare in the past but has been increasing in the incidence since the advent of pharmacological agents. Stuttering priapism is a recurrent form of ischemic priapism and its treatment goal is to prevent the recurrences of priapism and resultant erectile dysfunction. We present the case of a patient who took tadalafil and thereafter had idiopathic recurrent episodes of ischemic priapism during the sleep and we show several treatment options of stuttering priapism with review of recent related articles.

PURPOSE: The aim of this study was to evaluate the relationships among various psychosocial factors, behavior problems, and depressive symptoms reported by parents, and to investigate self-reported depression in Korean children using a community sample. MATERIALS AND METHODS: The sample consisted of 1279 children between 9 and 12 years of age. The children were evaluated using the Korean version of the Child Behavior Checklist (K-CBCL) and the Child Depression Inventory (CDI). RESULTS: The average self-reported depression score as measured by the CDI was 12.34 (SD: 6.79), and a cut-off point of 19 identified approximately 14% of the children as depressed. The group difference was identified by the age at which younger children were found to have higher CDI scores. Univariate logistic regression analysis showed that the high-CDI group and the low-CDI group differed in all behavioral domains identified in the parent-reported subscales of the K-CBCL. Age and father's education level were also independently associated with the risk for childhood depression. In addition, results from the logistic regression analyses indicated that parental reporting of problem internalization, total behavior problems, and social competence were independent predictors of child depression not identified by the anxious/depressed subscale. CONCLUSION: It is believed that extensive behavioral problems reported by parents and several sociodemographic factors are related to childhood depression. However, parents tend to under-report depressive symptoms relative to what their own children report. Thus, clinicians must consider the self-reports of children related to depression in their diagnosis and intervention, because reports of depressive symptoms from children are more valid measures than those from parents.

OBJECTIVE:Ultrasound estimation of amniotic fluid volume (AFI) is a critical component of antenatal surveillance. Alterations in AFI have classically been considered an indication of fetal compromise. Thus, this study was undertaken to determine whether there is any association between idiopathic polyhydramnios or oligohydramnios and adverse perinatal outcome. METHODS:Women delivered between December 1999 and November 2005, and who underwent ultrasonography from 26 to 41 weeks gestation were analyzed. Twenty-seven consecutive women with singleton pregnancies complicated by idiopathic polyhydramnios (amniotic fluid index>25) and 31 women complicated by oligohydraminos (amniotic fluid index<5) were included in this study. We reviewed the perinatal outcomes including preterm delivery, birth weight, primary cesarean section rate and indication, Apgar score (1-min and 5-min), and admission to NICU (neonatal intensive care unit). These findings were compared with those of 50 matched control patients with normal amniotic fluid volume. RESULTS:We observed that idiopathic oligohydramnios was significantly associated with primary perinatal outcome (Cesarean delivery for fetal distress) as well as secondary outcome variables such as birthweight, SGA (small for gestational age), Apgar score<7 at 1-min, 5-min, and NICU admission rates. On the other hand, idiopathic polyhydramnios did not correlate with any other perinatal outcome, except for rates of LGA (large for gestational age). CONCLUSION:The present study suggests that AFI is a weak predictor of perinatal outcome than has been classically suggested. But we demonstrated that the AFI identification of polyhydramnios was helpful in identifying LGA, and idiopathic oligohydramnios was a significant predictor of poor perinatal outcome.

OBJECTIVES: In the present study, we investigate the association between homozygosity of the 4-repeat allele (4/4) at the DRD4 and the response to the treatment with MPH in Korean children with ADHD. METHODS: The present study included 71 children with ADHD (8.231.78 years) from two children's psychiatric clinics in South Korea. All drug-naive children with ADHD were treated with MPH for about 8 weeks. The subjects who showed improvement of over 50% compared with the baseline ARS score after 8 weeks of treatment were termed as the 'good response' group. The subjects who showed an improvement of less than 50% were considered as the 'poor response' group. After genotyping for DRD4 were performed, we investigated correlation between homozygosity for 4-repeat allele at DRD4 and the response to MPH treatment. RESULTS: We found that while 79.5% (31/39) of the subjects with homozygosity of 4-repeat allele at DRD4 showed good response to MPH treatment, 68.8% (22/32) of the subjects without homozygosity of 4-repeat allele at DRD4 showed poor response to MPH treatment according to ARS scores assessed by their parents (chi2=16.762, df=1, p<0.01). We also found that while 61.5% (24/39) of the subjects with homozygosity of4-repeat allele at DRD4 showed good response to MPH treatment, 87.5% (28/32) of the subjects without homozygosity of the 4-repeat allele at DRD4 showed poor response to MPH treatment according to ARS scores assessed by their teachers (chi2=17.698, df=1, p<0.01). CONCLUSION: Our findings support an association between the homozygosity of 4-repeat allele and a good response to MPH in ADHD of Koreans.

Binder`s syndrome(maxillonasal dysplasia) is a disorder characterized by midface hypoplasia, flattened nose, convex upper lip, broad philtrum, crescent-shaped nostrils, acute nasolabial angle, absent anterior nasal spine and Class III malocclusion. Three defects(short maxilla, perialar flattening, and the hypoplastic nose) should be considered for appropriate correction method. A 25 years old man visited for correction of saddle nose deformity. The authors designed simple method for correction by using a silicone rubber and porous high density polyethylene sheet, Medpor(R), for nasal dorsal augmentation and the result was excellent. The most important part of Binder's syndrome correction seemed to be the correctioning the hypoplastic nose and it was highly effective only by simple correction of nasal augmentation with implants.

BACKGROUND: In 2001, the third report the National Cholesterol Education Program (NCEP) has concluded that LDL cholesterol levels should be a major goal for preventing coronary artery disease and atherosclerotic events. Those in the higher risk groups should then have lipoprotein analysis to determine LDL cholesterol levels. LDL cholesterol has traditionally been estimated by the Friedwald forrmula : LDL-C=total cholesterol-[high density lipoprotein cholesterol (HDL-C)+trigryceride/5]. However, when trigryceride level is >400 mg/dL, this formula is inaccurate. Therefore, We have compared the direct LDL cholesterol immunoseparation method with Friedwald formula from both normotriglyceridemic (triglyceride400 mg/dL). METHODS: The direct LDL cholesterol immunoseparation method was performed on 53 sera with triglyceride levels 61 to 1,684 mg/dL (classified as400 mg/dL : 31). Total cholesterol was measured enzymatic colorimetry. HDL cholesterol was measured in the supernatant after precipitating LDL by HDL cholesterol precipitating reagent containing dextran sulfate and magnesium chloride for serum. Direct LDL cholesterol was measured by immunoseparation method (Sigma Diagnostics, St Louis, Mo) that is based on selective absorption of HDL cholesterol and VLDL cholesterol by polystylene beads coated with goat polyclonal antibodies to human apolipoproteins. The cholesterol was measured by an enzamatic method on Hitachi 747. The linear regression and paird t-test were performed to evaluate the differences of data from Immunoseparation method and Friedwald formula. RESULTS: In triglyceride400 mg/dL, the LDL cholesterol value obtained by the direct LDL-C assay on the 31 frozen sera studied was significantly different from that of Friedwald formula (103+/-38.4; 50.4+/-56.2 mg/dL). Therefore, Friedwald formula is unreliable in triglyceride>400 mg/dL. CONCLUSION: Guidelines for treatment decisions, including diet and drug initiation, and therapeutic goals for high risk groups are based entirely on the LDL cholesterol level. At triglyceride levels >400 mg/dL, Friedwald fomula is inaccurate. Immunoseparation method is more rapid, higher specific, precise and helps monitor LDL lowering drugs and diets in triglyceride level>400 mg/dL.
