A 6-year-old girl visited us with a 4-week history of inflammatory, pustular, tender patches and plaques on the scalp, and a 3-day history of multiple, erythematous, indurated, tender, subcutaneous nodules on both pretibial areas. A swab was taken from the scalp lesion and colonies of Tiichophyton mentagrophytes grew on culture. The histopathological findings of the leg nodule were consistent with erythema nodosum. The patient was treated with oral itraconazole and deflazacort, combined with topical potassium permanganate solution. Erythema nodosum regressed two weeks later and the kerion of the scalp regressed six weeks after starting the treatment, leaving residual scarring alopecia. The patient was diagnosed as erythema nodosum probably induced by kerion celsi, that has not been reported in the Korean literature.

The mandibular contour determines the shape of the lower part of face and thus influences the appearance of head and neck. A prominent mandibular angle produce characteristic quadriangular, coarse and muscular appearance. To correct this facial contour to oval shape, the prominent angle can be contoured. the cutaneous approach has been used, but it leaves noticeble scar and has risk of facial nerve injury. Thus the intraoral approach has been used commonly. But because of restricition of operation field, the intraoral approach disadvantages of long operation time, high risk of complications. So, we have performed mandibular contouring procedure by new approach which uses reciprocating saw through stab incision under the mandibular body to correct the 9 patients of mandibular angle protrusion who visited our clinics recently. And we found that mandibular angle contouring by this new approach is easy, and makes the operation and recovery time shorter. There were no complications and cosmetic results were quite satisfactory.

PURPOSE: This study was to explore the predictors of subjective well-being of Korean older adults. METHOD: Data were collected through the structured interview using questionnaire with 199 older adults over 60 years. To identify the most effective predictor of the SWB, a stepwise regression analysis was conducted on each subscale of SWB measure. RESULTS: The results showed that receiving support from family was the effective factor of life satisfaction. Receiving support from family, health, optimism, economy, positive reappraisal, and giving support to family were the effective factors of emotional well-being. CONCLUSION: This study found that family support was the most important predictor on SWB among Korean older adults.

OBJECTIVE: Bipolar disorder patients often show excessive goal-directed and pleasure-seeking behavior during manic episodes and reduced hedonic capacity during depressive episodes, indicating that bipolar disorder might involve altered reward processing. As such, bipolar disorder subjects have been reported to show impaired reward learning in situations requiring integration of reinforcements over time. In this study, we examined characteristics of reward learning in euthymic patients with bipolar disorder using a probabilistic reward task. METHODS: We recruited 23 euthymic patients with bipolar disorder and 47 healthy subjects for the probabilistic reward task. This task is a reward-based paradigm to produce a response bias, in which correct identifications of two ambiguous stimuli are differently rewarded. The other dependent measures were the discriminability, hit rate and reaction time. RESULTS: Relative to comparison subjects, bipolar patients showed a reduced acquisition of response bias toward the more frequently rewarded stimulus (p<0.01). The overall reward learning was positively correlated with state and trait anxiety levels in bipolar patients (p<0.01). No significant differences of discriminability, hit rates, and reaction time were found between bipolar patients and controls. CONCLUSION: These findings suggest that euthymic patients with bipolar disorder may have deficits in reward learning related to anxiety.

OBJECTIVES: Autobiographical memory (ABM) is a special type of episodic memory, containing events that have occurred in a personal life. Overgeneral tendency of ABM refers to the retrieval of memory with only general and categorical descriptions rather than specific events. ABM specificity in depression and posttraumatic stress disorder is a robust finding with relation to cognitive vulnerability, affect regulation, problem-solving ability. It is also implicated in bipolar disorder with frequent relapses. In this study, we investigated whether ABM specificity was related to manic or euthymic mood states in patients with bipolar disorder. METHODS: Forty bipolar patients with manic and euthymic episodes and 25 healthy controls participated in this study. Prompted by 5 positively and 5 negatively valenced emotional cue words, each participant was instructed to recall positive or negative memories and describe them in detail. The one-way ANOVA was used to compare ABM scores and post-hoc analyses were done. RESULTS: Comapred to the healthy persons, the bipolar patients reported significantly more general than specific negative memories in both manic and euthymic episodes (p = 0.003). However, there was no significant difference between manic and euthymic patients (p = 0.074). CONCLUSIONS: These results suggest that overgeneral tendency of negative ABM may be a trait abnormality in bipolar disorder. Moreover, this phenomenon might be related to underlying cognitive deficits or affect regulation irrespective of the mood state.

PURPOSE: inhaled nitric oxide(iNO) is an excellent method for the postoperative pulmonary hypertension in congenital heart disease. But more detailed care is needed because of the development of rebound pulmonary hypertension after NO Withdrawal. We performed this study in order to discontinue the iNO successfully by way of presenting the adequate weaning and supplying methods. METHODS: Between January, 1998 and August, 1999 we sudied 10 patients who had rebound pulmonary hypertension(RPH) after iNO withdrawal. We completed the iNO in these patween the first the second trial of the weaning process. We tried to discover the differences between the first and second weaning process. We measured NO concentration at the start and just before NO withdrawal and during the period of weaning process. Moreover, to identify the iNO effects during the weaning of the iNO, we counted the degree of the change of PaO2/FiO2and mean PAP/SAP beween initial and at half of the initial NO concentration. RESULTS: Second weaning had a longer duration weaning process(11+/-0 cersus 5+/- hours, P<0.05), lower NO concentration just before NO withdrawal(2+/-.6 versus 4+/-ppm, P<0.05). In the change of the mean PAP/SAP and PaO2/FiO2as iNO was weaning from the initial iNO concentration to a half of the initial iNO concentration, the degree of increase in mean PAP/SAP(0.026+/-.07 versus 0.054+/-.07, P<0.05) and the degree of decrease in PaO2/FiO2(49+/-4 versus 65+/-2, P<0.05) were smaller in the second in the second weaning process than the first weaning process. CONCLUSION: A successful weaning of iNO can be performed with a low iNO concentration at the start and just before withdrawal and with the long duration iNO weaning process. Moreover, We speculate that the degree of change in the mean PAP/SAP and PaO2/FiO2at the half of the iNO weaning process are an indicator for the development of RPH.

BACKGROUND: The treatment for multi-drug resistant tuberculosis(MDRTB) is encountered to be important clinically, but there are still a few reports about it all over the world. So, we evaluated the outcomes of only chemotherapy for the pulmonary MDRTB retrosptctively. METHOD: We reviewed the clinical courses of 63 patients with pulmonary disease due to M.tuberculosis resistant to rifampin and isoniazid who were under follow-up between March 1996 and June 1996 after hospitalization at our hospital between January 1993 and January 1996. We performed cohort retrospective study for all these patient's records. Their regimens were selected individually and preferably included four medications that they had not been given previously and to which the strain was fully susceptible. RESULTS: The 63 patients(mean age, 43.2 years) had previously received a median 5.1drugs. Fifty two(82.5%) patients responded to chemotherapy(as indicated by negative sputum cultures for at least three consecutive months); eleven patients(17.5%) had no response, as shown by continually positive cultures. In a univariate analysis, an unfavorable response was significantly associated with greater number of resistant drugs before the current courses of therapy(relative risk 21.5; 95 percent confidence interval, 1.2-3.0; p<0.05). The mean period of follow-up was seventeen months. There was no relapse subsequently among the patients with responses. There was no death related to tuberculosis. CONCLUSION: In this report from National Masan Tuberculosis Hospital in Korea, multi-drug resistant pulmonary tuberculosis responded relatively well to carefully selected regimens.

OBJECTIVES: Cord blood stem cells have been widely used as donor cells for bone marrow transplantation recently. These cells can give rise to a variety of hematopoietic lineages to repopulate the blood. Recent observations reveal that some bone marrow cells and bone marrow stromal cells(MSCs) can grow to become either neurons or glial cells. It is, however, unclear whether or not there exists stems cells which can differentiate into neurons in the blood during the early stages of postnatal life. METHODS: Human cord blood stem cells were prepared from human placenta after full term delivery. To induce neuronal differentiation of stem cells, beta-mercaptoethanol was treated. To confirm the neuro-glial characteristics of differentiated stem cells, immunocytochemical stain for NeuN, neurofilament, glial fibrillary acidic protein(GFAP), microtubule associated protein2(MAP2) was performed. RT-PCR was performed for detecting nestin mRNA and MAP2 mRNA. RESULTS: We showed in this experiment that neuro-glial markers(NeuN, neurofilament, MAP2, GFAP) were expressed and axon-like cytoplasmic processes are elaborated in the cultured human cord blood stem cells prepared from new born placenta after full term delivery. Nestin mRNA was also detected in fresh cord blood monocytes. Conclusions: These results suggest that human cord blood derived stem cells may be potential sources of neurons in early postnatal life.
