PURPOSE: To assess the role of MRI in the diagnosis of uterine anomaly. MATERIAL AND METHODS: MRI(n:15), hysterosalpingography(n:7) and ultrasonography(n:7) were performed in 15 patients with suspected MullerJan duct anomaly. Nine cases were proved by operation and six cases were diagnoed with imaging and clinical findings. According to Buttram and Gibbons modified classification, the anomalies were 4 cases of class I, 2 cases of class III, one case of class IV, and 8 cases of class V. RESULTS: MRI enabled accurate diagnoses of anomalies in all cases, but HSG and USG showed wrong diagnoses in 3 of 7 cases and in 1 of 7 cases. CONCLUSION: MRI, especially T2-weighted images parallel to long axis of uterine corpus, was very useful in diagnosis of the Mullerian duct anomaly, because it could depict exactly the external fundal contour, intercornual distance, septum, transverse vaginal septum, and associated abnormalities such as hematocolpos and hematometra.

Lung cancer is the leading cause of cancer death for men and women in the industrialized world. It is desirable to detect disease at a stage when it is not causing symptoms and when control or cure is possible. If the screening test detects patients with the disease at an early stage, they can be examined to confirm the diagnosis and intervention can alter the natural history of the disease. The results of screening programs designed to detect early lung cancer using either conventional chest radiograph or sputum cytology are disappointing for a diagnostic screening test. Because of advances in helical CT imaging techniques, screening for lung cancer has been suggested as a possible method of improving outcome. Findings in recent publications suggest that substantial dose reduction is possible in chest CT. The advantages of low-dose CT are more sensitive than chest radiograph for detecting small pulmonary nodules that may be lung cancers, shorter scanning time than conventional chest CT scan without intravenous contrast injection, cheaper cost than standard CT, low radiation dose. However, the true clinical significance of the small tumors found by screening is still unknown, and their effect on mortality awaits future investigation. Furthermore, in addition to detecting an increased number of lung cancers, low-dose CT found at least one indeterminate nodule in many of all screened patients. The majority should be benign but evaluation of all these indeterminate nodules is not a trivial problem in routine practice. In conclusion, lung cancer screening with low-dose CT is a complex subject. The true effectiveness of lung cancer screening (a reduction in mortality from lung cancer) with low-dose CT can be determined through well-designed randomized control trials with enrolment of appropriate subjects.

The cytoskeleton consists of 3 filamentous components: intermediate filaments, microtubules, and actin filaments. Actin filaments continuously assemble and disassemble far out of equilibrium to adapt cells in response to external stimuli. Actin filaments organization and dynamic are controlled by a multitude of actin-binding proteins including actin-bundling proteins. L-plastin, expressed abundantly in lymphocytes and monocytes, is an actin-bundling protein that roles in immune defense and in metastatic invasion of cancer cells. The actin-bundling activity of L-plastin is regulated not only by intracellular calcium concentration, but by phosphorylation of Ser5. The actin-bundling activity of L-pastin decreases by increased calcium concentration but is promoted by phosphorylation of Ser5. The morphology changes and motility of cells requires continuous remodeling of actin filaments which demands the sensitive nature of L-plastin to Ca2+-signal, phosphorylation of Ser5, and probably additional regulation. This review briefly describes the structure and regulation of L-plastin, and roles for L-plastin in cancer invasion and in macrophages.

OBJECTIVES: The purpose of this study was to investigate the correlation of periodontitis with metabolic syndromes and menopause status. METHODS: The 2013 Korea National Health and Nutrition Examination Survey data of 645 postmenopausal and 663 premenopausal women were analyzed using the Pearson's chi-squared test and multiple regression analysis with the Statistical Package for the Social Sciences (PASW statistics) software version 21.0. Metabolic syndromes and community periodontal index (CPI) were analyzed. RESULTS: CPI 3, CPI 4 (P<0.001), and the prevalence of periodontal disease were significantly higher in the postmenopausal group (P<0.001). Periodontal disease was significantly higher (P<0.001) in postmenopausal women not using dental floss (2.69 times), hypertensive postmenopausal women (1.60 times), and premenopausal women with high blood glucose levels (1.67 times). In the multiple logistic regression analysis, after adjusting for age, smoking habit, and alcohol consumption, significant risk factors for periodontal disease were the lack of dental floss use (odds ratio [OR]: 1.83; 95% confidence interval [CI]: 1.26–2.67), menopause (OR: 1.71; 95% CI: 1.22–2.41), and number of metabolic syndromes (when 1 or 2, OR: 2.22 and 95% CI: 1.50–3.29; when 3 or more, OR: 2.22 and 95% CI: 1.58–3.13). CONCLUSIONS: In summary, menopause status is associated with periodontal disease. Therefore, oral health programs for middle-aged women with menopause and metabolic syndromes should be conducted to improve their oral health-related quality of life.

PURPOSE: This study tries to test mediating effects of hope and therapeutic relationship in the relation between general social functions and mental health recovery of community people with mental illness. METHODS: This study was carried out in a cross-sectional research design. The participants included 217 people with mental illnesses who were enrolled at eight Mental Health Welfare Centers in the Gyeonggi Province. Data were collected from February to May, 2018. The collected data were analyzed using a regression analysis, and SPSS PROCESS macro was used to test the mediating effects. RESULTS: This study analyzed the direct effects of general social functions on the hope, therapeutic relationship and mental health recovery. And general social functions had indirect effects on their mental health recovery via hope and therapeutic relationship. Both hope and therapeutic relationship had dual mediating effects in the influence of general social functions on mental health recovery. CONCLUSION: The role of hope and therapeutic relationship in the mental health recovery of community people with mental illness is important, and it is confirmed that hope is a powerful factor influencing mental health recovery.

OBJECTIVES: The purpose of this study was to investigate the reasons for unmet dental needs in Korea and to find ways to improve dental care accessibility by using data from the 6th National Health and Nutrition Survey. METHODS: This study was performed using data collected from the 6th National Health and Nutrition Examination Survey (KNHANES). A total of 2,251 subjects were selected for the study. Statistical analysis was performed using SPSS 21.0 on data files obtained according to complex sampling design, and a significance level of 0.05 was used. General characteristics of the subjects, oral health status, and unmet dental needs were examined for a complex sampling frequency analysis, and the differences in distribution were analyzed using chi-square analysis. Relevant factors were determined using logistic regression analysis. RESULTS: According to the logistic regression analysis, in Model 1, gender, household income, employment status, and subjective health status were found to be significantly related to unmet dental needs (P<0.05). In Model 2, subjective health status, subjective oral health status, and chewing difficulty were significantly related to unmet dental needs (P<0.001). Model 3 showed a significant relationship between subjective health status, subjective oral health status, chewing difficulty, periodontal disease, and unmet dental needs (P<0.001). CONCLUSIONS: We conclude that the reasons for the unmet dental needs in Korea are socioeconomic status, general health status, and oral health status. In the future, economic barriers to obtaining dental care need to be overcome through improvements in health insurance policies and systems and diversification of private insurance. Oral health should be improved through oral health education, which can create awareness and provide motivation for maintaining oral health.

Idiopathic pulmonary fibrosis (IPF), based on the 2018 international clinical practice guidelines, can be diagnosed with a usual interstitial pneumonia (UIP) pattern on high-resolution computed tomography (HRCT) and compatible clinical findings. Given that imaging is pivotal for IPF evaluation and diagnosis, more emphasis should be placed on the integration of clinical, radiological, and pathologic findings for multidisciplinary diagnosis. Interstitial lung abnormality (ILA), on the other hand, has a purely radiological definition based on the incidental identification of CT abnormalities. Taken together, differentiation between ILA and clinically significant interstitial lung disease (ILD) must be based on proper clinical evaluation. With this review, the recent updates in IPF diagnosis and the radiologic considerations for ILA can be well understood, which can be helpful for the proper diagnosis and management of patients with diffuse interstitial pulmonary fibrosis.
