BACKGROUND: Residual pleural thickening is frequently seen following treatment for tuberculous pleurisy, and pleural decortication is performend occasionally in patients with severe residual pleural thickening. However, predictive factors for the development of residual pleural thickening are uncertain at the initial diagnosis of the tuberculous pleurisy. Therefore, the purpose of this study was to identify the associated factors for residual pleural thickening at initial diagnosis. METHODS: We separated 63 patients diagnosed as tuberculous pleurisy into two groups; group 1 consisted of patients without residual pleural thickening and group 2 comprised patients with residual pleural thickening at the end of tuberculous pleurisy treatment. We analyzed the clinical characteristics, radiological findings, pleural biopsy and characteristics of pleural fluid between group 1 and group 2. RESULTS: The study population and clinical symptoms of the two groups were not significantly different and the duration of symptoms before treatment and the peripheral WBC were similar between the two groups. The presence of pulmonary tuberculosis, pleural fluid loculation or the amount of pleural effusion sid not differ significantly between the thwo groups. The incidence of positive AFB staining(group 1 : 8%, group 2 : 38%) and granuloma(group 1 : 30%, group 2 : 62%) on pleural biopsy specimens was significantly higher in group 2 than in group 1. Pleural fluid WBC and differential count, adenosine deaminase level, pH, preotein level or glucose level did not differ between the two groups. However, group 2 had higher LDH levels (1370±208mg/dl) than group 1 (860±71mg/dl, p<0.05). CONCLUSION: In tuberculous pleurisy, patients with residual pleural thickening following treatment demonstrated a higher incidence of posivive AFB staining and granuloma on the pleural biopsy specimens or higher LDH level in the pleural fluid than patients wihtout residual pleural thickening From these results, we speculate that the amonut of tuberculous bacilli and granuloma are probably correlated with residual pleural thickening in the tuberculous pleurisy.

OVJECTIVES: As the attention devoted to children's mental health increases, medical costs and burdens mount as well. In the present study, we evaluated the association between socioeconomic status (SES) and major child psychiatric symptoms. METHODS: The subjects of this study were children of recruited from a mental health screening program in the Seoul Sungbuk mental health center over the course of 3 months. To establish the SES of each child, we collected data about each child's medical insurance, years of parental education, household income, family structure and housing. 149 children& parents completed questionnaires including the Childhood Depression Inventory (CDI) and the Korean Attention Deficit Hyperactivity Disorder Rating Scale (K-ARS). RESULTS: The mean K-ARS-P score was 12.1+/-11.1 and the suspected prevalence of ADHD was 20.8% (n=31). The mean CDI score was 12.9+/-7.9, and the prevalence of suspected depression was 16.8% (25). Depressive symptoms and ADHD symptoms were both more severe than those observed in a previous epidemiologic study in Korea. Depressive symptoms were more closely associated with family SES status. CONCLUSION: SES status is one of the most important risk factors in the development of major child psychiatric symptoms. In our study we found that depressive symptoms in particular were most tightly associated with psychosocial factors. Evaluation of the risk factors, early screening and intervention for low SES children would be valuable mental health management tactics to implement in a community mental health system.

Stimulation of the medial forebrain bundle (MFB) can reinforce intracranial self-stimulation (ICSS) in rodents (i.e., reward-seeking behavior). The MFB stimulation produces a highly reliable behavioral output that enabled a clear distinction of the animal behavioral states between the non-ICSS and ICSS periods. However, the cortical states during these reward-seeking behaviors are not fully characterized in comparison to those during volitional behavior. This study was designed to characterize the cortical rhythms of and coherence between prefrontal cortex and hippocampus during the wheel-turning behavior reinforced by the ICSS in comparison to the wheel-turning without ICSS. We used a wheel for freely moving mice, which was programmed to deliver cathode currents through an electrode in the MFB at each one-quarter turn of the wheel to induce ICSS. The wheel-turning epochs were extracted from the pre-ICSS, ICSS and post-ICSS sessions and the prefrontal EEGs and the hippocampal LFPs in the epochs were analyzed with power and synchronization analyses. During the ICSS, the EEG power decreased at 6~10 Hz in the prefrontal cortex, while was not significantly altered in the hippocampus. Furthermore, we found that the phase synchrony between the prefrontal cortex and the hippocampus corresponding to information transmission between the two regions during reward-seeking motion decreased preceding MFB stimulation reinforced by ICSS. Our findings suggest that theta-activity can be reliably dissociated from active behavior if the animal is involved in self-stimulation.

Human studies of brain stimulation have demonstrated modulatory effects on the perception of pain. However, whether the primary somatosensory cortical activity is associated with antinociceptive responses remains unknown. Therefore, we examined the antinociceptive effects of neuronal activity evoked by optogenetic stimulation of primary somatosensory cortex. Optogenetic transgenic mice were subjected to continuous or pulse-train optogenetic stimulation of the primary somatosensory cortex at frequencies of 15, 30, and 40 Hz, during a tail clip test. Reaction time was measured using a digital high-speed video camera. Pulse-train optogenetic stimulation of primary somatosensory cortex showed a delayed pain response with respect to a tail clip, whereas no significant change in reaction time was observed with continuous stimulation. In response to the pulse-train stimulation, video monitoring and local field potential recording revealed associated paw movement and sensorimotor rhythms, respectively. Our results show that optogenetic stimulation of primary somatosensory cortex at beta and gamma frequencies blocks transmission of pain signals in tail clip test.

Absence seizures (AS) are generalized non-convulsive seizures characterized by a brief loss of consciousness and spike-and-wave discharges (SWD) in an electroencephalogram (EEG). A number of animal models have been developed to explain the mechanisms of AS, and thalamo-cortical networks are considered to be involved. However, the cortical foci have not been well described in mouse models of AS. This study aims to use a high density EEG in pathophysiologically different AS models to compare the spatiotemporal patterns of SWDs. We used two AS models: a pharmacologically induced model (gamma-hydroxybutyric acid, GHB model) and a transgenic model (phospholipase beta4 knock-out, PLCβ4 model). The occurrences of SWDs were confirmed by thalamic recordings. The topographical analysis of SWDs showed that the onset and propagation patterns were markedly distinguishable between the two models. In the PLCβ4 model, the foci were located within the somatosensory cortex followed by propagation to the frontal cortex, whereas in the GHB model, a majority of SWDs was initiated in the prefrontal cortex followed by propagation to the posterior cortex. In addition, in the GHB model, foci were also observed in other cortical areas. This observation indicates that different cortical networks are involved in the generation of SWDs across the two models.

Schwannoma commonly arises from Schwann cells of the neural sheath, and is rare in the groin region. Here, we describe a vaginal schwannoma incidentally detected by magnetic resonance imaging (MRI) in a patient with thigh pain. A 43-year-old woman presented with thigh pain with burning and tingling sensations in the medial aspect of her left thigh. MRI revealed a mass lesion of heterogeneous intensity 5.2 x 5.7 cm in the left vaginal wall. The mass was resected and histology revealed schwannoma.

PURPOSE: This study was planned to evaluate that a lecture employing medical drama could motivate students to have an interest in the professionalism of healthcare personnel, which has currently become a critical subject in the field of medical education. METHODS: We analyzed subject headings, learning objectives, and further plans developed by students and their responses after two drama modules, 'car crash' and 'refusal of instruction', which were selected based on the conditions made by our faculty members, were given through video or paper to our 121 second-grade medical and nursing students in year 2012. RESULTS: Meaningful subject headings and learning objectives developed by students were 58.2%~60.0% and 36.8%~38.0% and significantly more in the 'refusal of instruction' than the 'car crash' (p=0.000). According to the students' major, medical students developed significantly more than nursing students (p=0.000). In the analysis of responses, 91.7% of students reported as impressive to the educational modules and 55.3% of them described their ideas associated with healthcare professionalism. CONCLUSION: Our study results suggest a possibility that the educational module employing selected medical drama could motivate students' healthcare professionalism.

OBJECTIVE: The fears and side effects of a prolonged hormone replacement therapy on the postmenopausal symptoms reinforce a growing interest about alternatives. The present study was performed to investigate whether black cohosh root extract (BCRE) can be used or not as an alternative to hormone replacement therapy (HRT) in order to relieve postmenopausal symptoms. MATERIAL & METHODS: Randomized, double-blind prospective clinical trial examined the effects of BCRE and HRT on Kupperman index, biochemical bone markers, lipid profiles, and side effects in 74 women with postmenopausal symptoms. Treatments included placebo (Festal(R)) (n=12), BCRE (Feramin(R)) (n=32) and HRT (Premarin(R)) (n=30) for 3 months. Kupperman index, biochemical bone markers (osteocalcin and deoxypyridinoline), and lipid profiles (total cholesterol, triglyceride and HDL-cholesterol) were measured at 0, 1 and 3 months. Side effects were checked at 3 months. RESULTS: BCRE was significantly effective in lowering of Kupperman index as much as HRT at two control times (1 month: p<0.05, 3 months: p<0.001). It also showed slightly favorable effects on biochemical bone markers and lipid profiles but not statistically significant. Fewer side effects were seen in BCRE than HRT. CONCLUSION: BCRE appears to be a safe and effective alternative to HRT for early postmenopausal symptoms and may be especially useful in women with intolerances or contraindications to traditional HRT.

BACKGROUND: Mycoplasma spp. occasionally colonize the genital tract and these organisms are some of the most important contaminants in cell culture laboratories and cell banks. We analyzed the Mycoplasma contamination rates in the donated cord blood units (CBUs) before cell processing. METHODS: A total of 151 CBUs that were donated with informed consent (November 3rd~December 28th, 2006) were randomly selected and enrolled in the study. We performed blood culture and Mycoplasma DNA PCR assay with using samples from the collection bags before processing. RESULTS: All of the CBUs were obtained from full-term (gestational age 37~42 weeks) deliveries. Two units showed positive results on blood culture however, Mycoplasma DNA is not found in the tested samples. CONCLUSION: The contamination rates of Mycoplasma in the CBUs, which are donated from the mothers who have full-term delivery and no pregnancy complications, are extremely low. The donated CBUs could be used in culture and for an expansion process without concern of incurring pre-processing Mycoplasma contamination. The rate of Mollicute contamination in the CBUs could become clear with the results of performing Ureaplasma assay.
