PURPOSE: The purpose of this study was to know psychological characteristics of psychogenic non-epileptic seizure (PNES) patients by analyzing profiles of Minnesota Multiphasic Personality Inventory (MMPI). In addition, we tried to investigate whether there are differences of MMPI profiles, depending on the gender and age.METHODS: We included 65 patients with non-epileptic psychogenic seizures. Their diagnosis was based on clinical features, provocative test and confirmed by video-EEG monitoring.RESULTS: The results of MMPI analysis did not show any statistically significant differences of quantitative scoring on the main clinical scales. However, additional analysis indicated that patients with PNES had some characteristics of more somatic complaints and depressive mood. According to sex difference, the MMPI profiles of female group showed an increase in the depression scale (D-Pt), whereas those of male group revealed an increased in the somatisation (Hs-Hy). According to age difference, MMPI profiles of adolescent group had the characteristics of personality pattern with a tendency toward somatisation. MMPI profiles of adult group had more depressive tendency. This study suggests that profiles of MMPI, according to the gender and age, can have different characteristics.CONCLUSIONS: Clinical consideration of those factors may be helpful for improving the care of PNES patients.

Urticaria pigmentosa (UP) is the most common variant of cutaneous mastocytosis. Primarily a disease of childhood, in over one-half of the cases onset is before 2 years of age, and in 90%, the disease is confined to the skin. UP precedes the diagnosis of systemic mastocytosis and is more common in adults than in children. Therefore, systemic examination should be performed in patients with UP. We report a case of adult-onset UP with systemic involvement.

Autism spectrum disorder (ASD) is characterized by persistent deficits within two core symptom domains: social communication and restricted, repetitive behaviors. Although numerous studies have reported psychopharmacological treatment outcomes for the core symptom domains of ASD, there are not enough studies on fundamental treatments based on the etiological pathology of ASD. Studies on candidate medications related to the pathogenesis of ASD, such as naltrexone and secretin, were conducted, but the results were inconclusive. Oxytocin has been identified as having an important role in maternal behavior and attachment, and it has been recognized as a key factor in the social developmental deficit seen in ASD. Genetic studies have also identified associations between ASD and the oxytocin pathway. As ASD has its onset in infancy, parents are willing to try even experimental or unapproved treatments in an effort to avoid missing the critical period for diagnosis and treatment, which can place their child in an irreversible state. While therapeutic application of oxytocin for ASD is in its early stages, we have concluded that oxytocin would be a promising therapeutic substance via a thorough literature review focusing on the following: the relationship between oxytocin and sociality; single nucleotide polymorphisms as a biological marker of ASD; and validity verification of oxytocin treatment in humans. We also reviewed materials related to the mechanism of oxytocin action that may support its potential application in treating ASD.

Background: High LDL-cholesterol (LDL-C) is an established risk factor for cardiovascular disease and is considered an important therapeutic target. It can be measured directly or calculated from the results of other lipid tests. The Friedewald formula is the most widely used formula for calculating LDL-C. We modified the Friedewald formula for a more accurate and practical estimation of LDL-C. Methods: Datasets, including measured triglyceride, total cholesterol, HDL-cholesterol, and LDL-C concentrations were collected and assigned to derivation and validation sets. The datasets were further divided into five groups based on triglyceride concentrations. In the modified formula, LDL-C was defined as total cholesterol − HDL-cholesterol − (triglyceride/adjustment factor). For each group, the adjustment factor that minimized the difference between measured LDL-C and calculated LDL-C using modified formula was obtained. For validation, measured LDL-C and LDL-C calculated using the modified formula (LDL-CM), Friedewald formula (LDL-CF), Martin-Hopkins formula (LDL-CMa), and Sampson formula (LDL-CS) were compared. Results: In the derivation set, the adjustment factors were 4.7, 5.9, 6.3, and 6.4 for the groups with triglyceride concentrations <100, 101–200, 201–300, and >300 mg/dL, respectively. In the validation set, the coefficient of determination (R2) between measured and calculated LDL-C was higher for LDL-CM than for LDL-CF (R2=0.9330 vs. 0.9206). The agreement according to the National Cholesterol Education Program Adult Treatment Panel III classification of LDL-C was 86.36%, 86.08%, 86.82%, and 86.15% for LDL-CM, LDL-CF, LDL-CMa, and LDL-CS, respectively. Conclusions We proposed a practical, improved LDL-C calculation formula by applying different factors depending on the triglyceride concentration.

BACKGROUND: Severe alopecia areata (AA) is difficult to treat. Treatment modalities such as topical and systemic immune modulators, corticosteroids and topical sensitizers have been tried. Among them, encouraging RESULTS have been reported with high dose pulse corticosteroid therapy. OBJECTIVE: The aim of this study was to determine the effectiveness of a high dose corticosteroid pulse therapy in patients with severe AA compared with a group treated with oral cyclosporine with low dose corticosteroid. METHODS: A total of 105 patients with severe AA were treated with high dose corticosteroid pulse therapy and 41 patients those were treated with oral cyclosporine (3~5 mg/kg/day) with low dose methylprednisolone (2.5~5 mg/day). RESULTS: Therapeutic effect of high dose corticosteroid pulse therapy was better in shorter disease duration (<6 months, 81.4%;>6~12 months, 52.6%;>13 months, 37.3%) and less extensive type (AA multiplex, 80.0%; alopecia totalis, 41.2%; alopecia universalis, 27.8%). Therapeutic effect of oral cyclosporine with low dose corticosteroid therapy was better in less extensive type (AA multiplex, 75.0%; alopecia totalis, 41.2%; alopecia universalis, 25.0%). Disease duration did not significantly affect treatment response. High dose corticosteroid pulse therapy was more effective method (65.7%) than combination regimen of oral cyclosporine with low dose methylprednisolone (46.3%), especially in the case of shorter disease duration (p<0.05). CONCLUSION: High dose corticosteroid pulse therapy might be a more effective therapy for severe AA than other treatments, especially when in the acute stage (<6 months).

The massive reorganization of microtubule network involves in transcriptional regulation of several genes by controlling transcriptional factor, nuclear factor-kappa B (NF-kappaB) activity. The exact molecular mechanism by which microtubule rearrangement leads to NF-kappaB activation largely remains to be identified. However microtubule disrupting agents may possibly act in synergy or antagonism against apoptotic cell death in response to conventional chemotherapy targeting DNA damage such as adriamycin or comptothecin in cancer cells. Interestingly pretreatment of microtubule disrupting agents (colchicine, vinblastine and nocodazole) was observed to lead to paradoxical suppression of DNA damage-induced NF-kappaB binding activity, even though these could enhance NF-kappaB signaling in the absence of other stimuli. Moreover this suppressed NF-kappaB binding activity subsequently resulted in synergic apoptotic response, as evident by the combination with Adr and low doses of microtubule disrupting agents was able to potentiate the cytotoxic action through caspase-dependent pathway. Taken together, these results suggested that inhibition of microtubule network chemosensitizes the cancer cells to die by apoptosis through suppressing NF-kappaB DNA binding activity. Therefore, our study provided a possible anti-cancer mechanism of microtubule disrupting agent to overcome resistance against to chemotherapy such as DNA damaging agent.

BACKGROUND: Androgenic alopecia (AGA) is characterized by the local and gradual transformation of terminal scalp hair into vellus hair, which has a shorter and thinner shaft. It is the most common form of hair loss in people with a genetic predisposition for baldness. OBJECTIVE: The aim of this study was to evaluate the prevalence, AGA type, family history, co-morbidity diseases, stress factors and endocrine factors of AGA patients. METHODS: We examined a total of 432 male and female AGA patients who visited for two years at the Department of Dermatology, School of Medicine, Chung-Ang University. RESULTS: There were 2.06 times more men (291 patients) than women (141 patients) among the study subjects. Most of the men were in their twenties (108, 37.1%), however, most of the women were in their forties (42, 29.7%). In the 291 male patients, Norwood class IIIv was dominant (120 patients, 41.2%). In the 141 female patients, Ludwig class I was dominant (87 patients, 61.7%). 219 (75.2%) of the 291 male patients and 81 (73.6%) of the 141 female patients had a family history of AGA. 224 (76.9%) of the 291 male patients and 101 (53.4%) of the 141 female patients had a co-morbidity disorder. The most common among these disorders in both the male and female patients was seborrheic dermatitis. Stress factors were observed in 162 (55.6%) of the 291 male patients and in 78 (55.3%) of the 141 female patients. The most common stress factor in both the male and female patients was work tasks. The serum testosterone levels was increased in 51 (17.5%) of the 291 male patients and in 20 (14.1%) of the 141 female patients. CONCLUSION: Most of the study results are compatible with those of our previous study. Yet the following results were different: (1) the number of female AGA patients in their forties is increasing; and (2) stress was found to be associated with AGA in both the male and female patients.

BACKGROUND: In dental intravenous sedation, continuous intravenous infusion of a low-dose drug requires an infusion pump such as a syringe pump. To develop a new syringe pump for clinical use, the functions of the pump must meet certain international standards. Various safety and efficacy tests must be performed on the syringe pump, as stipulated by these standards, and an approval must be received from the approving agency based on such test results. METHODS: The authors of the present study developed a novel syringe pump and performed efficacy evaluation by testing its infusion speed at 1 and 25 ml/h, and infusion performance testing at 2 and 24 h. Moreover, performance evaluation was conducted by comparing the novel pump to an existing pump with the infusion speed varied from 1 to 5 ml/h. RESULTS: In the efficacy testing on the newly developed syringe pump, infusion with the infusion speed initially set to 1 ml/h resulted in infusion speeds of 1.00 and 0.99 ml/h in the 2- and 24-h assessment, respectively. Changing the infusion speed setting to 25 ml/h resulted in an infusion speed of 25.09 and 23.92 ml/h in the 2- and 24-h assessment, respectively. These results show no significant differences when compared with other commercially available pumps. CONCLUSIONS: The efficacy testing of the newly developed syringe pump showed the accuracy to be within tolerance. Based on these findings, we believe that the newly developed syringe pump is suitable for clinical use.

PURPOSE: 'Programming' describes the process that stimulus at a critical period of development has lifelong effects. The fact that low birth weight links to the risk of elevated blood pressures in adult life is well known. This study aims to examine whether this link is evident in the newborn by investigating the relationship of the intrauterine growth indices and neonatal blood pressure(BP). METHODS: We studied 127 neonates who were born at Ewha Womans' Hospital and their mothers enrolled our cohort study during pregnancy. Data on the mothers and details of the birth records were tracked and collected from medical charts. Neonatal BP was measured within 24 hours after birth. RESULTS: Neonatal SBP was positively correlated to intrauterine growth indices; birth weight(BW)(r= 0.4), head circumference(HC)(r=0.4), and birth height(r=0.3). However, an inverse relationship existed, between HC/BW ratio and neonatal SBP(r=-0.4). After adjusting for the baby's sex, maternal BP, and gestational age, neonatal SBP still associated with intrauterine growth indices. SBP was 7 mmHg higher in the highest BW group(> or =90 percentiles) compared to the lowest group(<10 percentiles). On the other hand, SBP was 17 mmHg lower in the highest HC/BW group(> or =90 percentiles) compared in the lowest group(<10 percentiles). CONCLUSION: This study could not find the evidence that intrauterine growth retardation affect on elevated neonatal BP. It suggests that the initiating events of BP programming may occur during postnatal growth period. To identify the critical starting period that intrauterine growth retardation leads to elevated BP, a study tracking BP changes from birth to childhood is required.
