Recurrent incarceration of the retroverted gravid uterus at term - two times transvaginal caesarean section:a case report

INTRODUCTION: Persistent retroversion of a gravid uterus (incarceration) in the third trimester is an extremely rare diagnosis and is only scarcely been described. Its prevalence may lead to increased foetal mortality and maternal morbidity. CASE PRESENTATION: We present a case where a 35-year-old patient had undiagnosed (recurrent) uterine incarceration at term. Operative delivery proved difficult due to distorted anatomy. Therefore, in our case delivery of the fetus through transvaginal caesarean section was required. CONCLUSION: This case report discusses the diagnosis and management of (recurrent) incarceration of the retroverted uterus at term resulting in two successful transvaginal caesarean sections. In presenting this case, we aim at improving awareness, diagnosis and treatment of the retroverted incarcerated gravid uterus

Somatostatin receptor scintigraphy in patients with carcinoid tumors

In 80% to 90% of patients with carcinoids, tumor sites can be detected with [111In-DTPA-D-Phe1]-octreotide scintigraphy. Unexpected, additional localizations are reported in one-third to two-thirds of patients. In a group of 52 patients, we analyzed the results of various combinations of octreotide scintigraphy and conventional imaging. Octreotide scintigraphy, alone or in combination with other imaging modalities, led to the detection of more tumor sites than any combination of conventional imaging techniques. The combination of octreotide scintigraphy, chest radiography, and ultrasonography of the upper abdomen led to the detection of lesions in all patients in whom they could be demonstrated by any imaging means, with a sensitivity of 87% in terms of the number of detected lesions. The calculated cost for this imaging regimen was higher than for the combination of conventional imaging as applied in our group. However, the benefit was the detection of at least one lesion in 11% of patients in whom with conventional imaging no abnormalities were found. Moreover, if the results from our patient group were extrapolated to a group of 100 patients, the advantage in terms of the number of extra lesions detected would be 65 extra lesions per 100 patients. The detection of more tumor sites in patients who are known to have one tumor localization with conventional imaging may be essential when deciding whether to perform surgery. Octreotide scintigraphy can be used to localize tumors, direct the choice of medical therapy, and (expected in the near future) select patients for radiotherapy. The impact on patient management is fourfold: Octreotide scintigraphy may detect resectable tumors that would be unrecognized with conventional imaging techniques; it may prevent surgery in patients whose tumors have metastasized to a greater extent than can be detected with conventional imaging; it may direct the choice of therapy in patients with inoperable tumors; and in the future it may be used to select patients for radionuclide therapy

miRetrieve-an R package and web application for miRNA text mining

microRNAs (miRNAs) regulate gene expression and thereby influence biological processes in health and disease. As a consequence, miRNAs are intensely studied and literature on miRNAs has been constantly growing. While this growing body of literature reflects the interest in miRNAs, it generates a challenge to maintain an overview, and the comparison of miRNAs that may function across diverse disease fields is complex due to this large number of relevant publications. To address these challenges, we designed miRetrieve, an R package and web application that provides an overview on miRNAs. By text mining, miRetrieve can characterize and compare miRNAs within specific disease fields and across disease areas. This overview provides focus and facilitates the generation of new hypotheses. Here, we explain how miRetrieve works and how it is used. Furthermore, we demonstrate its applicability in an exemplary case study and discuss its advantages and disadvantages

Beyond the completeness of physics: a preliminary groundwork for a dispositional emergentism

In recent years, the shape of the discourse concerning the structure and subsistence of fundamental properties has taken on new dimensions with respect to their synoptic framing of special science entities. Specifically, challenges to the completeness of physics stemming from evidence of non-linear emergence in the special sciences have attenuated the traditional reliance of accounts of fundamental properties as being derived from a base which takes for granted the fundamentality of physically compatible properties. As such, in the course of this paper, preliminary assumptions from which an account of a monistically dispositional picture of fundamental properties compatible with the non-linear emergent properties evidenced by special science entities might be developed will be explored such that both the dispositional monist program might be salvaged as well a potential basis developed from which non-linear, strongly metaphysically emergent dynamics might be synoptically provided for

The Endothelium as a Target for Anti-Atherogenic Therapy:A Focus on the Epigenetic Enzymes EZH2 and SIRT1

Endothelial cell inflammatory activation and dysfunction are key events in the pathophysiology of atherosclerosis, and are associated with an elevated risk of cardiovascular events. Yet, therapies specifically targeting the endothelium and atherosclerosis are lacking. Here, we review how endothelial behaviour affects atherogenesis and pose that the endothelium may be an efficacious cellular target for antiatherogenic therapies. We discuss the contribution of endothelial inflammatory activation and dysfunction to atherogenesis and postulate that the dysregulation of specific epigenetic enzymes, EZH2 and SIRT1, aggravate endothelial dysfunction in a pleiotropic fashion. Moreover, we propose that commercially available drugs are available to clinically explore this postulation
