TL;DR: Deeper understanding of disease pathogenesis and the unique characteristics of IBD in the Asia–Pacific region, combined with reasonable and practical guidelines for drug management and the future use of biological agents would improve the therapeutic outlook of I BD in this region.
Abstract: At the present there are no large-scale epidemiologic data on inflammatory bowel disease (IBD) in the Asia-Pacific region, but several studies have shown an increased incidence and prevalence of IBD in this region. Compared to the West, there appears to exist a time lag phenomenon. With regard to the two main forms of IBD, ulcerative colitis (UC) is more prevalent than Crohn's disease (CD). In addition to geographic differences, ethnic differences have been observed in the multiracial Asian countries. Moreover, the genetic backgrounds are different in the Asian compared to Western patients. For instance, NOD2/CARD15 variants have not been found in Asian CD patients. In general, the clinical course of IBD seems to be less severe in the Asia-Pacific region than in Western countries. Diagnosis of IBD in this region poses special problems. The lack of a gold standard for the diagnosis of IBD, and the existence of a variety of infectious enterocolitis with similar manifestations to those of IBD make the differential diagnosis particularly difficult. So far, Western diagnostic criteria have been introduced for the diagnosis of IBD. A stepwise approach to exclude non-IBD enterocolitis also must be introduced, and a definite diagnosis must include typical histological features. In some patients, follow up and therapeutic trials might be necessary to obtain a definitive diagnosis. A better understanding of the pathogenesis of IBD will allow the development of better diagnostic markers. The management of IBD also poses some special problems in the Asia-Pacific Region. There is often a delay in using proper medications for IBD, and alternative local remedies are still widely used. With a combination of Western guidelines and regional experiences, similar principles can be used for induction and maintenance of remission. A stepwise selection of medications is advocated depending on the extent, activity and severity of the disease. Comprehensive and individualized approaches are suggested for different IBD patients. Deeper understanding of disease pathogenesis and the unique characteristics of IBD in the Asia-Pacific region, combined with reasonable and practical guidelines for drug management and the future use of biological agents would improve the therapeutic outlook of IBD in this region.

TL;DR: The clinical characters and prognosis of ovarian cancers complicating pregnancy are similar to those of nonpregnant, reproductive-age women, and management depends on histology of the tumor, stage of the tumors, and the term of the pregnancy.
Abstract: The aim of this study was to summarize our experience of ovarian cancer diagnosed during pregnancy, to review the literature concerned, and to discuss the rationale for therapy. Twenty-two patients of ovarian malignancies complicating pregnancy were treated at Peking Union Medical College Hospital between 1985 and 2003. Data on treatment and follow-up were reviewed, and their outcomes were analyzed by survival analysis. The incidence of ovarian carcinoma complicating pregnancy in the series was 0.073/1000 pregnancies. Nine (40.9%) were found with ovarian malignant germ cell tumors, six (27.3%) with low malignant potential tumors, five (22.7%) with invasive epithelial tumors, and two (9.1%) with sex cord stromal tumors. Sixteen (72.7%) of the patients were diagnosed in stage I and had achieved complete remission. Four of the five in advanced stage died. Ascites presenting at diagnosis implies advanced disease and gloomy prognosis. The mean follow-up was 47.8 months. The prognosis was significantly related with stage and histologic type (P < 0.05). Thirteen healthy live babies were recorded in this group, and one premature newborn died of respiratory distress syndrome. The clinical characters and prognosis of ovarian cancers complicating pregnancy are similar to those of nonpregnant, reproductive-age women. Management depends on histology of the tumor, stage of the tumor, and the term of the pregnancy. In most of cases, conservative surgical treatment could be performed with adequate staging and debulking equal to the treatment of nonpregnant women. Chemotherapy is not contraindicated during the second or third trimester, but the choice of couple must be considered.
