BACKGROUND: Bronchial asthma is an inflammatory disease of the airways that is associated with airway remodeling. The vascular endothelial growth factor (VEGF) is a potent, multifunctional cytokine that contributes to angiogenesis and inflammation. Matrix metalloproteinase-9 (MMP-9) is a major proteolytic enzyme that induces bronchial remodeling in asthma. However, there is no data available on the possible role of the VEGF or on the potential relationship between the VEGF and MMP-9 in acute asthma. Therefore, the VEGF was studied to determine whether or not it participates in airway inflammation during acute asthma. An additional aim of this study was to determine whether or not the VEGF levels correlated with the MMP-9 levels in the sputum of acute asthma patients. METHODS: Both the VEGF and MMP-9 levels were measured by an enzyme immunoassay and zymographic analysis in the sputum of patients with either stable asthma or with acute asthma. The VEGF and MMP-9 levels were also evaluated during a spontaneous asthma attack. RESULTS: The VEGF levels were significantly higher in the sputum of acute asthmatic patients than in either the stable patients the control subjects. The VEGF levels in the sputum during asthma exacerbation were significantly higher than those on the remission days, and those levels decreased after decreased after asthma therapy. In acute asthmatic patients, the VEGF levels in the sputum correlated with the number of neutrophils and eosinophils. In addition, a significant correlation was established between the VEGF and MMP-9 levels in the sputum. CONCLUSION: These results suggest that VEGF overproduction is associated with airway inflammation during acute asthma and is related to the MMP-9 function.

PURPOSE: Our purpose was to investigate psychological problems and clinical outcomes in children with psychogenic non-epileptic seizures (PNES). MATERIALS AND METHODS: We retrospectively reviewed the data of 25 patients who were diagnosed with PNES between 2006 and 2012. RESULTS: Twenty-five children with PNES, aged 8 to 19 years (mean 13.82), were referred to psychiatrists for psychiatric assessment. On their initial visit, 72% of patients had comorbid psychological problems, including depression, anxiety, conduct disorder, adjustment disorder, Attention Deficit Hyperactivity Disorder, schizophrenia, and bipolar disorder. Among these, depression was the most frequent (36%). Predisposing and triggering factors included familial distress (40%), social distress (24%), and specific events (20%). The following treatment was advised based on the results of the initial psychological assessment: 3 patients regularly visited psychiatric clinic to assess their clinical status without treatment, nine underwent psychotherapy, and 13 received a combination of psychotherapy and psychopharmacological therapy. At the mean follow-up of 31.5 months after diagnosis, 20 patients (80%) were event-free at follow-up, three (12%) showed reduced frequency, and two (8%) experienced persistent symptoms. CONCLUSION: The outcomes of PNES in children are much better than those in adults, despite a high rate of psychological comorbidities.

PURPOSE: This study sought to evaluate the clinical outcomes of various therapeutic modalities, including newly-developed anti-epileptic drugs (AEDs), prednisolone, ketogenic diet (KD) epilepsy surgery, and vagus nerve stimulation (VNS), in treating intractable childhood epilepsy. METHODS: Data of refractory epilepsy patients (n=297) treated from July 1995 through April 2003 at the epilepsy center of Sanggye Paik Hospital were retrospectively analyzed. RESULTS: Newly-developed AEDs were primarily prescribed to 290 patients, although only 20 patients (6.9%) maintained a seizure- free state. Of 138 patients for whom prednisolone was prescribed, 58 patients (42.0%) showed complete seizure controls while 41 patients experienced relapse. KD was attempted and evaluated at 12 months in 162 patients, at which time 74 (45.7%) remained on the diet and 68 (42.0%) showed seizure reduction of greater than 50%, including 37 (22.8%) who were completely seizure free. Epilepsy surgery was undergone in 38 patients, and Engel class I was identified in 25 (65.8%) patients. VNS was administered to five patients, only two of whom obtained a seizure reduction of more than 50%. RESULTS: Taken together, these findings suggest that considerable controls over intractable childhood epilepsy can be gained through KD and epilepsy surgery, whereas prednisolone treatment leads to somewhat more frequent relapses, and newly-developed AEDs are comparatively limited in their controls of refractory epilepsy.

We report a case of rheumatoid nodule of the right knee in a 55-year-old woman which on the basis of MR images was misdiagnosed as soft tissue sarcoma. Rheumatoid nodules occur in up to 20% of adult patients with rheumatoid arthritis and most patients with rheumatoid nodules are rheumatoid factor positive. The nod-ules are most commonly located between the skin and an underlying bony prominence. In this case, the patient had a history of rheumatoid arthritis and a soft tissue mass was present in the lateral aspect of the right knee. T1-weighted images revealed a mass of similar signal intensity to that of muscle, and on T2 weighted im-ages, a central portion of high signal intensity was noted. Enhanced T1 weighted images demonstrated periph-eral rim enhancement. The mass extended to subcutaneous tissue, with penetration of lateral patellar retinacu-lum. Excisional biopsy was performed, and the pathologic diagnosis was rheumatoid nodule. Although its radi-ologic findings are non-specific, rheumatoid nodule should - in appropriate clinical settings - be included in the differential diagnosis of a predominently solid or centrally necrotic periarticular soft tissue.

PURPOSE: This study is to evaluate the efficacy and safety of vagus nerve stimulation (VNS) in intractable childhood onset epilepsy by reviewing our experiences. MEHTHOD: Involved in the study are five patients who underwent VNS from July 23th, 1999 and had been followed up over 12 months. We reviewed data prospectively collected with a focus on clinical features, therapeutic outcomes and safety, developmental progress, and EEG findings. RESULTS: Three patients were classified as Lennox-Gastaut syndrome. One patient of the two remaining patients had gelastic seizure caused by hypothalamic harmatoma, while the other patient had partial seizure with secondary generalization. Among the 5 patients, one patient showed a seizure frequency reduction rate of about 50% from baseline in 3 months after VNS implantation and more than 90% in 12 months, 2 patients of about 50% in 3 months and of about 75% in 12 months, but the other two patients didn't show any change in seizure frequency. Side effects such as hoarseness, dyspnea during sleep and wound infection could be controlled simply through the adjustment of output current or wound revision. However, efficacy in cognitive function and EEG findings was not satisfactory. CONCLUSIONS: VNS might be an effective adjunctive therapy for intractable childhood epilepsy and transient side effects can be controlled without discontinuation of VNS therapy.

BACKGROUND: There are many risk factors for osteoporosis in patients with chronic obstructive pulmonary disease(COPD). These include smoking, a low body mass index, insufficient exercise, and the use of glucocortcoids. However, there is lack of data on the incidence of osteoporosis according to the different glucocorticoid administration methods in patients with COPD. This study compared the incidence of osteoporosis according to the different administration methods of glucocorticoid. METHODS: A matched case-controlled study (gender, age, cumulative steroid dose and pack-years of smoking) was conducted. Forty-five patients with documented COPD for at least a 3 year duration and a cumulative glucocorticoid dose above 1,000 mg were enrolled in study. The patients were classified into the following three groups. First, fifteen patients received continuous inhaled glucocorticoid with intermittent oral steroids but had no admission history due to an acute exacerbation(Group I). Secondly, fifteen patients received a multiple course of oral steroids with additional inhaled glucocorticoid but had no admission history due to their acute exacerbation(Group II). Lastly, fifteen patients received intermittent oral or inhaled glucocorticoids and had an admission history due to the acute exacerbation with intravenous steroid treatment for at least 2 weeks per year(Group III). The enrolled patients had apulmonary function test and bone densitometry performed at the lumbar spine and femoral neck. RESULTS: The patients from Group III had significantly high incidence of osteoporosis in the lumbar and femoral neck compared to Group I and Group II (p<0.01). CONCLUSION: The incidence of osteoporosis in patients with COPD appears to be strongly affected by the method of steroid administration. This result suggests that intravenous steroid administration is strongly associated with the risk of osteoporosis.

OBJECTIVE: Lung cancer arises after a series of morphological changes, which take several years to progress from normal epithelium to invasive cancer. Multiple molecular changes and growth factors factor production have been documented in lung cancers, both small cell and non-small cell types. Insulin-like growth factors(IGFs) are important mitogenic and anabolic peptides, both in vivo and in vitro, and are thought to be significant autocrine-paracrine factors involved in normal and malignant cell proliferation. In this study, we have investigated (delete) the degree of expression of IGF-1 on the immunohistochemical staining in human non-small cell lung cancer(NSCLC) cells and small cell lung cancer (SCLC) cells were investigated. METHODS: Immunohistochemical staining for IGF-1 was performed in 15 cases of small cell carcinoma, 15 cases of squamous cell carcinoma, 15 cases of adenocarcinoma, and 12 cases of bronchoalveolar carcinoma. RESULTS: The NSCLC cells showed significantly increased expression The expression of IGF-1 on the immunohistochemical staining significantly increased in NSCLC cells than in SCLC cells. CONCLUSION: These results suggest that IGF-1 are expressed the expression of IGF-1 in human lung cancer cells(.), and the (The) immunohistochemical staining of IGF-1 in lung cancer cell lines may help in differentiation of may assist in the differentiation of NSCLC and SCLC.
