Purpose: This study was aimed to examine the gap between predicted cesarean section rate and real cesarean section rate and it's determining factors of 44 tertiary hospitals. Method: This study is a cross-sectional analysis using the data of 25,623 deliveries in 2009 drawn from homepage of Health Insurance Review and Assessment Service. Data were analyzed with t-test, F-test, Scheff$\acute{e}$ test, and logistic regression. Result: There were statistically significant differences in the gap of cesarean section rate (more gap indicates higher quality of delivery) by grade of nurse staffing and delivery cases. Hospitals with nurse staffing grade 1 to 2 had more possibility to be classified into higher grade in quality of delivery (OR 5.67, 95% CI 1.07-30.08). Also hospitals with over 500 delivery cases had more possibility be classified into higher grade in quality of delivery (OR 4.92, 95% CI 1.14-21.23, respectively). Conclusion: The finding suggests that grade of nurse staffing may influence the real cesarean section rate because nurses do a vital role to prevent unnecessary cesarean section. Further study is required to provide evidence that nurse staffing influence on patient outcome and cost-effectiveness in order to obtain adequate number of nursing staffs.

Objectives : The aim of this study is to investigate the relationship between chronic low grade inflammation theory, psoriasis, and herbal medicine. Methods : We reviewed recent studies on the relationship between chronic low-grade inflammation, psoriasis, and herbal medicine through Pubmed. Results : The pathological basis for psoriasis is the action of inflammatory mediators by the activation of the immune response, which can be a cause of various cardiovascular, metabolic and psychological symptoms of psoriasis patients, in addition to skin lesions. The herbal medicines improve these inflammatory conditions and improve local lesions through herbal medicine such as Qingdai, which have a strong inhibitory effect on IL-17,22 production. Conclusions : Herbal medicines used in psoriasis are thought to be effective not only for the improvement of local psoriasis lesions through anti-inflammatory effect but also for the improvement of systemic inflammation associated with chronic low grade inflammation.

Objective : Diagnosing tumor progression and pseudoprogression remains challenging for many clinicians. Accurate recognition of these findings remains paramount given necessity of prompt treatment. However, no consensus has been reached on the optimal technique to discriminate tumor progression. We sought to investigate the role of magnetic resonance perfusion (MRP) to evaluate tumor progression in glioma patients. Methods : An institutional retrospective review of glioma patients undergoing MRP with concurrent clinical follow up visit was performed. MRP was evaluated in its ability to predict tumor progression, defined clinically or radiographically, at concurrent clinical visit and at follow up visit. The data was then analyzed based on glioma grade and subtype. Resusts : A total of 337 scans and associated clinical visits were reviewed from 64 patients. Sensitivity, specificity, positive and negative predictive value were reported for each tumor subtype and grade. The sensitivity and specificity for high-grade glioma were 60.8% and 87.8% respectively, compared to low-grade glioma which were 85.7% and 89.0% respectively. The value of MRP to assess future tumor progression within 90 days was 46.9% (sensitivity) and 85.0% (specificity). Conclusion : Based on our retrospective review, we concluded that adjunct imaging modalities such as MRP are necessary to help diagnose clinical disease progression. However, there is no clear role for stand-alone surveillance MRP imaging in glioma patients especially to predict future tumor progression. It is best used as an adjunctive measure in patients in whom progression is suspected either clinically or radiographically.

Germline mutations in cancer causing genes result in high risk of developing cancer throughout life. These cancer predisposition syndromes (CPS) are especially prevalent in childhood brain tumors and impact both the patient's and other family members' survival. Knowledge of specific CPS may alter the management of the cancer, offer novel targeted therapies which may improve survival for these patients, and enables early detection of other malignancies. This review focuses on the role of CPS in pediatric high grade gliomas (PHGG), the deadliest group of childhood brain tumors. Genetic aspects and clinical features are depicted, allowing clinicians to identify and diagnose these syndromes. Challenges in the management of PHGG in the context of each CPS and the promise of innovative options of treatment and surveillance guidelines are discussed with the hope of improving outcome for individuals with these devastating syndromes.

The aim of this study was to evaluate the readability and suitability of patients' education materials on DM. A total of 34 materials on DM from public health centers, general hospitals, and internet web sites were evaluated for readability by 'graded system of vocabulary', and suitability by 'The Korean version of SAM(Suitability Assessment of Materials)'. On the average, 28.3% of 1st grade reading level words, 27.1% of 5th grade level and over were included in educational materials. For suitability, 6(17.6%) were judged superior, 20(58.8%) adequate, 8(23.6%) inadequate. The reading level of the materials was higher than the recommended reading level(6th grade reading level). For suitability, most of materials were inadequate in some of items such as 'summary or review included', 'context given', 'interaction used'. It is proposed that in the development of patients' educational materials, health literacy of target population should be considered.

Low-grade fibromyxoid sarcoma (LGFMS), a soft tissue tumor that has high recurrence and metastasizing potential, rarely occurs in the head and neck region. Therefore, the treatment for LGFMS in the facial area is challenging in terms of cosmetic and functional maintenance. The authors report a case of LGFMS in the posterior nasal cavity. It was completely removed in parallel with the nasal endoscopic and oral approach, but the lower margin was closed by preserving the soft palate. The patient is well without any recurrence or metastasis after 5 years of follow-up.

Low-grade fibromyxoid sarcoma (LGFMS) is very rarely seen, and it commonly arises from the deep soft tissues of the lower extremities. Histologically, it is characterized by the presence of bland spindle cells with mainly storiform pattern of growth, set in alternating areas with a myxoid or fibrous stroma. The immunohistochemical reaction of this tumor permits a positive diagnosis of low grade fibromyxoid sarcoma and allows its distinction from a number of other benign and malignant soft tissue tumor. We report this rare case together with the review of the literature.

Low grade fibromyxoid sarcoma is a recently recognized, uncommon soft tissue neoplasm. It has a tendency to develop in deep soft tissue of young adults and a possibility of local recurrence or distant metastasis. Diagnostic criteria have not been well defined and this tumor has not been accepted as a distinct entity. Histologically, it is characterized by the presence of bland spindle cells with mainly whorled pattern of growth, set in alternating areas with a myxoid or fibrous stroma. Careful consideration of the morphological and immunohistochemical features of this tumor permit a positive diagnosis of low grade fibromyxoid sarcoma and allow its distinction from a number of other benign and malignant soft tissue neoplasms. We experienced a low grade fibromyxoid sarcoma in chest wall and report this case with a review of the literature.

Mucoepidermoid carcinomas, first reported by Volkman(1895), form 6% to 9% of all salivary tumors. Two thirds affecting the parotid gland and the remaining third, the minor glands. As we could know from its name, mucoepidermoid carcinomas originate from ductal epithelium including squamous, mucous-secreting, and undifferentiated intermediate cells. Histologically, it is classified as well-differentiated (low grade), moderately-differentiated(intermediate grade), and poorly-differentiated (high grade) types and the treatment method and prognosis are influenced from its histological grade. We have experienced two cases of mucoepidermoid carcinoma treated surgically with good results and now would like to report these with review of literatures.

Objectives: This systematic review addressed the question: "What is the prevalence of apical periodontitis in patients prior to hematopoietic cell transplantation?" Materials and Methods: A systematic search was conducted in MEDLINE/PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Grey Literature Report. Eligibility criteria were based on the condition, content, and population strategy: the condition was the radiographic prevalence of apical periodontitis, the content comprised patients scheduled for hematopoietic stem cell transplantation, and the population consisted of adult and pediatric patients. The revised Risk of Bias in Nonrandomized Studies of Exposure tool was used to assess the quality of studies. The Grading Recommendations Assessments, Development, and Evaluation (GRADE) tool was used to assess the quality of evidence. Results: Eight studies were included in this review. The average number of patients with apical periodontitis was 15.65% (range, 2.1%-43.34%). One study was classified as having a very high risk of bias, 1 with a high risk of bias, and 6 with some concern for bias. GRADE analysis showed a very low certainty of evidence. Significant limitations concerning the absence of control over confounding variables were identified. Conclusions: With the caveat of the very low quality of evidence in the studies reviewed, there was a low to moderate prevalence of apical periodontitis in patients prior to undergoing hematopoietic cell transplantation.
