Objectives: ：This study was aimed to investigate whether 1) sexual dimorphism in subcortical gray matter volumes (GMV) and the length ratio between the second and fourth digits (2D:4D) would be found and 2) 2D:4D would have associated with subcortical GMV in healthy elderly people. Methods: ：Sixty-two females aged 70.3±6.3 (mean±SD) years and 23 males aged 70.4±4.9 years were recruited from the Dementia Clinic in the Pusan National University Hospital. The subjects with the clinical dementia rating scale-sum of boxes (CDR-SB) total score greater than 2.0, any psychiatric or neurological disease, or any pathologic lesion on brain MRI other than micro-angiopathy were excluded. The 2D:4D of the left and right hands were measured 3 times each. Volumetric segmentation of T1-weighted MRI scans was done by Freesurfer software (v7.1.1.1). Results: ：2D:4Ds of males were smaller than those of females significantly on repeated measures ANOVA. The males’ thalamus, putamen, hippocampus in both hemispheres and the right amygdala were larger than females’. These differences were not significant after controlling for age, education and total intracranial volume (ICV). In the females, the left 2D:4D was negatively correlated with the left hippocampal volume. In the males, 2D:4D was positively correlated with the volumes of ipsilateral or contralateral thalamus, hippocampus, amygdala and accumbens. These correlations were not significant after Bonferroni’s correction, except for the right accumbens. Conclusions ：Sexual dimorphism of 2D:4D is preserved in healthy elderly people. There is a significant correlation between the right 2D:4D and GMV of the accumbens in males.

Objective: Although maintenance treatment for mood disorders is important, the treatment discontinuation rate is reported to be high. This study aimed to investigate the dropout rates and associated factors in mood disorders. Methods: The patients in a mood disorder clinic (n = 535) were examined. Demographic and clinical factors, scores of psychometric scales, time to dropout from initial treatment in patients with bipolar disorder (BP) (n = 288) and depressive disorder (DD) (n = 143) were evaluated based on database of the mood disorder clinic. Results: Among the studied patients with BP and DD, 50% showed dropout in 4.05 and 2.17 years, respectively. The mean survival times were 8.90 years in bipolar disorder I (BP-I), 5.19 years in bipolar II disorder, 3.22 years in bipolar disorder not otherwise specified, 4.24 years in major depressive disorder, and 4.03 years in other depressive disorders.In the multivariate Cox proportional hazards regression model in the BP group, diagnosis BP-I was found to be significantly related to the decrease in dropout rate (hazard ratio [HR] = 0.22, p = 0.001); however, increased past suicide attempt number was significantly related to the increase in dropout rate (HR = 1.13, p = 0.017). In the DD group, none of anxiety disorders as comorbidity, increased scores of openness, and extraversion personality were related to the increase in dropout rate. Conclusion Patients with BP, especially BP-I, showed a lower dropout rate as compared to patients with other mood disorders.

Erlotinib (Tarceva(R)) is a new anti-cancer agent which acts by inhibiting epidermal growth factor receptor (EGFR) signal transduction. It is currently used in the treatment of advanced stage non-small cell lung cancer and pancreatic cancer. We report a case of acneiform eruption and paronychia induced by erlotinib in a 69-year-old man. The patient visited our clinic with multiple erythematous papules and pustules on the face, periungual erythema and pus discharge, xerosis, fissures on the sole. He had taken erlotinib for the treatment of recurred lung cancer for 4 weeks. The skin lesions were partially improved with oral pyridoxine, corticosteroid and topical antibiotics.

Ectopic nail is characterized by growth of nail-like tissue in a location other than the nail bed. It is an extremely rare disorder that can be either congenital or acquired from incidents such as trauma. An 8-year old female presented with a complaint of a nail-like lesion on the dorsal surface around the center of the right fifth toe. It had been present for 3 years, while the patient continuously clipped it upon growth. The fifth toe was initially injured by a chair that had fallen on that toe 4 years prior to her visit. There was no associated bony deformity or other physical changes in the nail. A clinical diagnosis of ectopic nail was made and it was surgically excised under local anesthesia. The histopathological examination revealed a normal nail unit and there was no recurrence during the 6 month follow-up period.

Juvenile xanthogranuloma (JXG) is a benign, normolipaemic, self-healing condition and a type of histiocytosis that occurs most frequently in infants and children, although adults may also be affected. This condition usually presents with a solitary or multiple cutaneous lesions and occasionally with extracutaneous lesions, especially the eye, lung, liver, kidney and pericardium. Histologically, JXG represents an accumulation of histiocytes lacking Birbeck granules (non-Langerhans cell), which can be differentiated from the Langerhans cells by specific staining techniques. The lesions may be excised for diagnostic, cosmetic or symptomatic reasons. We report a case of juvenile xanthogranuloma that occurred in the nasal cavity and testis for the first time.

MDM2 is a substrate of caspase-3 in p53-mediated apoptosis. In addition, MDM2 mediates its own ubiquitination in a RING finger-dependent manner. Thus, we investigated whether MDM2 is degraded through a ubiquitin-dependent proteasome pathway in the absence of p53. When HL-60 cells, p53 null, were treated with etoposide, MDM2 was markedly decreased prior to caspase-3-dependent retinoblastoma tumor suppressor protein (pRb) and poly (ADP- ribose) polymerase (PARP) cleavages. Moreover, down-regulation of MDM2 level was not coupled with its mRNA down-regulation. However, the level of MDM2 was partially restored by proteasome inhibitors such as LLnL and lactacystin, even in the presence of etoposide. Our results suggest that, in the p53 null status, MDM2 protein level is decreased by proteasome-mediated proteolysis prior to caspase-3-dependent PARP and pRb cleavages.

Objective: Though anger was highly associated with eveningness in general population, there is no study on the relationship between chronotype and anger-related characteristics in bipolar or depressive disorders. This study aimed to investigate the difference of anger-related characteristics according to chronotypes in bipolar or depressive disorders. Methods: Patients with bipolar or depressive disorders (n=238) were included in this study. Their chronotypes and anger-related characteristics were assessed with a self-evaluation of the Composite Scale of Morningness (CSM), the State Trait Anger Expression Inventory (STAXI) and the Anger Coping Scale (ACS). Results: The eveningness group in patients with mood disorders showed the highest scores of anger-trait (p<0.001), anger-expression (p=0.002) and anger-in (p<0.001) in STAXI subscales, verbal aggression (p=0.010) in ACS subscales among three groups, but the morningess group showed the lowest scores of these subscales among three groups. However, there were no significant differences in all subscales of the STAXI and ACS according to diagnostic subtypes in the Friedman test. Conclusion The results of this study suggested that eveningness in patients with mood disorders might be related to anger proneness and maladaptive anger coping. To manage anger emotion in the patients with mood disorders, therapeutic interventions to modulate eveningness might be helpful.

OBJECTIVE: A popular design for the investigation of such effects, including effects of parent-of-origin (imprinting), maternal genotype, and maternal-fetal genotype interactions, is to collect deoxyribonucleic acid (DNA) from affected offspring and their mothers and to compare with an appropriate control sample. We investigate the effects of estimation of maternal, imprinting and interaction effects using multimodal modeling using parents and their offspring with schizophrenia in Korean population. METHODS: We have recruited 27 probands (with schizophrenia) with their parents and siblings whenever possible. We analyzed 20 SNPs of 7 neuronal genes in chromosome 18. We used EMIM analysis program for the estimation of maternal, imprinting and interaction effects using multimodal modeling. RESULTS: Of analyzed 20 single nucleotide polymorphisms (SNPs), significant SNP (rs 2276186) was suggested in EMIM analysis for child genetics effects (p=0.0225438044) and child genetic effects allowing for maternal genetic effects (p=0.0209453210) with very stringent multiple comparison Bonferroni correction. CONCLUSION: Our results are the pilot study for epigenetic study in mental disorder and help to understanding and use of EMIM statistical genetics analysis program with many limitations including small pedigree numbers.
