OBJECTIVE: We examined a functional model of acquired capability for suicide, which was elaborated from the “Interpersonal-Psychological Theory of Suicide”. METHODS: A total of 6,027 Korean community subjects were recruited from The Korean Epidemiologic Catchment Area study conducted in 2011. The subjects were assessed systematically using the Korean version of the Composite International Diagnostic Interview version 2.1, the Korean version of the Barratt Impulsiveness Scale, and the Korean version of the Mood Disorder Questionnaire. We used structural equation modeling to identify potential factors contributing to a suicide attempt. RESULTS: Most aspects of the model were supported by the data and “the short-term enhancer for the acquired capability for suicide” had direct effects on suicide attempts. However, the suicidal planning effects of “the short-term enhancer for the acquired capability for suicide” were eliminated by the rule of parsimony. CONCLUSION: The main finding was that “the short-term enhancer for the acquired capability for suicide” is relevant to suicide attempts when it's direct, indirect, and reciprocal effects are tested within a more complete system of relationships than found in existing studies. The implications of these findings are discussed with regard to future conceptual work and empirical research.

OBJECTIVE: The goal of this study was to examine the association between IQ and suicide in psychiatric patients. METHODS: We conducted a nested case-control study using data obtained from psychiatric patients affiliated with a general hospital in Seoul, Korea. In a one-to-two ratio the psychiatric patients who died of suicide (Suicide Group; n=35) were matched to those who didn't (Non-suicide Group; n=70) by age, gender, psychiatric diagnosis and approximate time of first treatment. IQ was measured using the Korean version of the Wechsler Adult Intelligence Scale-Revised. RESULTS: There were no significant differences in any type of IQ between suicide patients and non-suicide patients. Logistic regression showed no evidence of an association between IQ and suicide. CONCLUSION: These results do not support the existence of an association between IQ and suicide.

OBJECTIVES: There is a moderate but significant association between schizophrenia and violence. The purpose of this study is to investigate the relationship between violence and brain cognitive functions in schizophrenic patients who have committed homicide using neuropsychological tests. METHODS: The study involved three group of subjects: schizophrenics who have committed homicide (n=51), schizophrenics who have not committed homicide (n=50) and normal control (n=50). Intelligence test (K-WAIS), memory test (Rey-Kim Memory Test) and executive function test (Stroop test, WCST) as well as Positive and Negative Syndrome Scale (PANSS) and Structured Interview for DSM-IV Personality (SIDP) were administered by trained researchers. RESULTS: There were no significant differences in demographic variables among groups. Schizophrenic patients showed overall cognitive deficit in intelligence, memory and executive functions, regardless of homicide behavior. Homicidal schizophrenic group was not significantly different from non-homicidal schizophrenic group in every cognitive domain. There was no significant correlation between index scores of cognitive functions and Life History of Aggression assessment (LHA). However, index scores of cognitive functions were negatively correlated with the PANSS and schizotypal trait scores. CONCLUSION: Cognitive dysfunction is common across both schizophrenic groups. It doesn't significantly correlate with homicidal experience, but it correlates with the schizophrenic symptom domains.

Endometriosis is defined as the abnormal growth of endometrial tissue outside the uterine cavity, but in rare cases may also occur on the skin. Cutaneous endometriosis frequently develops at the site of a prior abdominal or pelvic procedure, although apparent spontaneous occurrence has been reported. We present a case of non-symptomatic, cutaneous endometriosis in the episiotomy scar. The patient had no evidence of concurrent pelvic endometriosis.

BACKGROUND: The treatment of patients with lymphomatoid papulosis is unsatisfactory. Because a curative therapy is not available and none of the available treatment modalities affects the natural course of the disease, the short-term benefits of active treatment should carefully be balanced against the potential side effects. OBJECTIVE: The purpose of this study was to determine the effectiveness and safety of methotrexate in the treatment of lymphomatoid papulosis. METHOD: Twelve patients with a clinicopathological diagnosis of lymphomatoid papulosis were treated with low-dose methotrexate (5-20mg/week), and clinical efficacy and adverse effects were evaluated. RESULTS: The male-to-female ratio was 1: 1.4, and age distribution ranged from 11 to 65 years, with a mean age of 41 years. Histopathologic types classified by Willemze's classification included type A (10 cases), type B (0 cases), and type C (2 cases). All patients responded to low-dose methotrexate, and the level of control was judged to be `excellent' (no or rare lesions between doses), `good' (few lesions between doses), `fair' (improvement but new lesions continued to develop), or `poor' (no improvement observed) in 7 (58%), 2 (17%), 3 (25%), and 0 (0%) of patients respectively. All three patients in the `fair' group (the group relatively less responsive to methotrexate) were female and included both patients who were histopathologic type C. Adverse effects only included nonspecific gastrointestinal discomfort in two patients. CONCLUSION: Low-dose methotrexate (5-20mg/week) is effective and well-tolerated in most patients with lymphomatoid papulosis.

Median raphe cysts are rare mid-line developmental cysts, which can arise at any point between the external urethral meatus and the anus. They most commonly affect the ventral aspect of the penis, usually near the glans. They tend to be solitary, unilocular cysts, and the inner lining is usually composed of pseudostratified columnar epithelium. We present a case of a 3-year-old boy with a median raphe cyst affecting the glans penis. The cyst, located near the urethral meatus, was slightly pruritic and 0.3cmx0.3cmx0.1cm in size. A shave biopsy, followed by CO2 laser ablation was performed, and histopathological examination revealed a unilocular cyst lined with pseudostratified columnar epithelium, which showed decapitation secretion in part. For 2 years fallawing the shave biopsy, no clinical evidence of recurrence has been observed.

Porokeratosis is a group of disorders characterized by epidermal keratinization associated with cornoid lamella. Porokeratosis has been described as having five distinct clinical subtypes: Mibelli or plaque type, disseminated superficial actinic porokeratosis, linear porokeratosis, punctate porokeratosis, porokeratosis palmaris et plantaris disseminata. We describe a 61-year-old Korean woman presented with porokeratosis palmaris et plantaris disseminata.

Hidradenoma papilliferum is a rare benign neoplasm that occurs almost exclusively on the skin of the female anogenital region. It is usually a slow-growing cystic dermal mass that can be either asymptomatic or ulcerate and bleed, and represents an adenoma with apocrine differentiation. We present a case of hidradenoma papilliferum in a 46-year old woman with a erythematous to brownish papule on the left labium majora and the typical histopathologic findings.

We report the case of a 48-year-old man presenting with a pubic nodule and multiple ulcers on penis and scrotum. He had a kidney transplantation two months ago and has been taking cyclosporine, prednisolone, and mycophenolate mofetil. The biopsy specimen from the nodule showed vasculitis and multiple cytomegalic cells in dermis. The biopsy specimen from the scrotal ulcer showed a cluster of multinucleated giant cells and acantholysis in epidermis and cytomegalic cells and vasculitis in dermis, suggestive of HSV infection in epidermis and CMV infection in dermis. Specific immunoperoxidase for CMV antigens positively stained cytomegalic endothelial cells and fibroblasts in both specimens. Evidence of CMV viremia as pp65 was detected in circulating polymorphonuclear leukocytes by immunocytochemical tests although there was no evidence of other organ involvement. Immediately, he was placed on intravenous ganciclovir therapy for 3 weeks. The lesions cleared leaving scars and he was discharged in good general condition.

Aquired fibrokeratoma is a rare, benign tumor which occurs most frequently on the fingers. Because of the digital predilection, a term of digital fibrokeratoma has been frequently used. We present here two cases of acquired fibrokeratoma occurring on the prepatellar area and the proximal nail bed which are unusual sites of this lesion. A skin-colored, hyperkeratotic tumor with finger-like projection was found on the prepatellar area of a 29-year-old man and a round pedunculated nodule was found on the proximal nail bed of second finger of a 74-year-old woman. Histopathologic examination revealed typical features of acquired fibrokeratoma.
