Magnetic resonance imaging findings in pseudo-Meigs' syndrome associated with a large uterine leiomyoma: a case report

<p>Abstract</p> <p>Introduction</p> <p>Pseudo-Meigs' syndrome is a rare pathological entity characterized by the presence of a pelvic mass other than an ovarian fibroma. The mass is associated with ascites with or without hydrothorax.</p> <p>Case presentation</p> <p>We describe the case of a 41-year-old Caucasian woman with a large uterine leiomyoma associated with massive ascites. A magnetic resonance imaging scan showed a large subserosal leiomyoma with multiple areas of cystic degeneration.</p> <p>Conclusion</p> <p>To the best of our knowledge, this is the first reported case of pseudo-Meigs' syndrome caused by a uterine leiomyoma and diagnosed using magnetic resonance imaging. The pathophysiology of this syndrome and the role of magnetic resonance imaging are emphasized in this case report.</p

LifeCLEF 2016: Multimedia Life Species Identification Challenges

International audienceUsing multimedia identification tools is considered as one of the most promising solutions to help bridge the taxonomic gap and build accurate knowledge of the identity, the geographic distribution and the evolution of living species. Large and structured communities of nature observers (e.g., iSpot, Xeno-canto, Tela Botanica, etc.) as well as big monitoring equipment have actually started to produce outstanding collections of multimedia records. Unfortunately, the performance of the state-of-the-art analysis techniques on such data is still not well understood and is far from reaching real world requirements. The LifeCLEF lab proposes to evaluate these challenges around 3 tasks related to multimedia information retrieval and fine-grained classification problems in 3 domains. Each task is based on large volumes of real-world data and the measured challenges are defined in collaboration with biologists and environmental stakeholders to reflect realistic usage scenarios. For each task, we report the methodology, the data sets as well as the results and the main outcom

Mesenteric panniculitis of the sigmoid colon: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Mesenteric panniculitis of the sigmoid colon is a rare occurrence in surgical practice. The aim of this article is to present a case of mesenteric panniculitis of the sigmoid colon and a short review of the literature.</p> <p>Case presentation</p> <p>We reviewed the hospital record of a 63-year-old man who presented with a palpable mass in the left abdomen and clinical signs of a partial bowel obstruction. The pre-operative impression was a possible cancer of the sigmoid colon. A laparotomy was performed through a midline incision. The mesentery was found to be markedly thickened, constricted and puckered. The normal architecture of the adipose tissue had been lost and replaced with an irregular nodular mass. The microscopic pathologic sections demonstrated a chronic reactive inflammatory process with an exuberant proliferation of fibroblasts and fibrocytes. The adipose tissue contained scattered areas of steatonecrosis with foci of lipid-laden macrophages, lymphocytes and plasma cells. The sigmoid colon and its mesocolon were resected. The postoperative course was uneventful and the patient was discharged in good condition, and followed up for the next two years.</p> <p>Conclusion</p> <p>Mesenteric panniculitis of sigmoid is an extremely rare entity of unknown origin in which the normal architecture of the mesentery is replaced by fibrosis, necrosis and calcification. On gross examination the alterations may be mistaken for a neoplastic process. A frozen section may be necessary for confirmation of the diagnosis. When the advanced inflammatory changes became irreversible and bowel obstruction occurs, resection may be indicated.</p

Long-term morphological and hormonal follow-up in a single unit on 115 patients with adrenal incidentalomas

We investigated the natural course of adrenal incidentalomas in 115 patients by means of a long-term endocrine and morphological (CT) follow-up protocol (median 4 year, range 1–7 year). At entry, we observed 61 subclinical hormonal alterations in 43 patients (mainly concerning the ACTH–cortisol axis), but confirmatory tests always excluded specific endocrine diseases. In all cases radiologic signs of benignity were present. Mean values of the hormones examined at last follow-up did not differ from those recorded at entry. However in individual patients several variations were observed. In particular, 57 endocrine alterations found in 43 patients (37.2%) were no longer confirmed at follow-up, while 35 new alterations in 31 patients (26.9%) appeared de novo. Only four alterations in three patients (2.6%) persisted. Confirmatory tests were always negative for specific endocrine diseases. No variation in mean mass size was found between values at entry (25.4±0.9 mm) and at follow-up (25.7±0.9 mm), although in 32 patients (27.8%) mass size actually increased, while in 24 patients (20.8%) it decreased. In no case were the variations in mass dimension associated with the appearance of radiological criteria of malignancy. Kaplan–Meier curves indicated that the cumulative risk for mass enlargement (65%) and for developing endocrine abnormalities (57%) over time was progressive up to 80 months and independent of haemodynamic and humoral basal characteristics. In conclusion, mass enlargement and the presence or occurrence over time of subclinical endocrine alterations are frequent and not correlated, can appear at any time, are not associated with any basal predictor and, finally, are not necessarily indicative of malignant transformation or of progression toward overt disease

Diabetes related risk factors did not explain the increased risk for urinary incontinence among women with diabetes. The Norwegian HUNT/EPINCONT study

<p>Abstract</p> <p>Background</p> <p>Previous studies have shown an association between diabetes mellitus (DM) and urinary incontinence (UI) in women, especially severe UI. The purpose of this study was to investigate whether diabetes related variables could explain this association.</p> <p>Methods</p> <p>The study is part of the EPINCONT study, which is based on the large Nord-Trøndelag Health Study 2 (HUNT 2), performed in the county of Nord-Trøndelag, Norway, during the years 1995 - 1997. Questions on diabetes and UI were answered by a total of 21 057 women aged 20 years and older. Of these 685 were identified as having diabetes, and thus comprise the population of our study. A variety of clinical and biochemical variables were recorded from the participants.</p> <p>Results</p> <p>Blood-glucose, HbA1c, albumine:creatinine ratio (ACR), duration of diabetes, diabetes treatment, type of diabetes, cholesterol and triglycerides did not significantly differ in women with and without UI in crude analyses. However, the diabetic women with UI had more hospitalizations during the last 12 months, more homecare, and a higher prevalence of angina and use of oestrogene treatment (both local and oral/patch). After adjusting for age, BMI, parity and smoking, there were statistically significant associations between any UI and angina (OR 1.89; 95% CI: 1.22 - 2.93), homecare (OR 1.72; 95% CI: 1.02 - 2.89), and hospitalization during the last 12 months (OR 1.67; 95% CI: 1.18 - 2.38). In adjusted analyses severe UI was also significantly associated with the same variables, and also with diabetes drug treatment (OR 2.10; 95% CI: 1.07 - 4.10) and stroke (OR 2.47; 95% CI: 1.09 - 5.59).</p> <p>Conclusion</p> <p>No single diabetes related risk factor seems to explain the increased risk for UI among women with diabetes. However, we found associations between UI and some clinical correlates of diabetes.</p

LifeCLEF 2015: Multimedia Life Species Identification Challenges

International audienceUsing multimedia identification tools is considered as one of the most promising solutions to help bridging the taxonomic gap and build accurate knowledge of the identity, the geographic distribution and the evolution of living species. Large and structured communities of nature observers (e.g. eBird, Xeno-canto, Tela Botanica, etc.) as well as big monitoring equipments have actually started to produce outstanding collections of multimedia records. Unfortunately, the performance of the state-of-the-art analysis techniques on such data is still not well understood and is far from reaching the real world’s requirements. The LifeCLEF lab proposes to evaluate these challenges around three tasks related to multimedia information retrieval and fine-grained classification problems in three living worlds. Each task is based on large and real-world data and the measured challenges are defined in collaboration with biologists and environmental stakeholders in order to reflect realistic usage scenarios. This paper presents more particularly the 2014 edition of LifeCLEF, i.e. the pilot one. For each of the three tasks, we report the methodology and the datasets as well as the official results and the main outcomes

The conservation status of the world's freshwater molluscs

With the biodiversity crisis continuing unchecked, we need to establish levels and drivers of extinction risk, and reassessments over time, to effectively allocate conservation resources and track progress towards global conservation targets. Given that threat appears particularly high in freshwaters, we assessed the extinction risk of 1428 randomly selected freshwater molluscs using the IUCN Red List Categories and Criteria, as part of the Sampled Red List Index project. We show that close to one-third of species in our sample are estimated to be threatened with extinction, with highest levels of threat in the Nearctic, Palearctic and Australasia and among gastropods. Threat levels were higher in lotic than lentic systems. Pollution (chemical and physical) and the modification of natural systems (e.g. through damming and water abstraction) were the most frequently reported threats to freshwater molluscs, with some regional variation. Given that we found little spatial congruence between species richness patterns of freshwater molluscs and other freshwater taxa, apart from crayfish, new additional conservation priority areas emerged from our study. We discuss the implications of our findings for freshwater mollusc conservation, the adequacy of a sampled approach and important next steps to estimate trends in freshwater mollusc extinction risk over time
