Extensive chronic xanthogranulomatous intra-abdominal inflammation due to Mycoplasma hominis mimicking a malignancy: a case report

Introduction: While infectious peritonitis is a common occurrence in patients with liver cirrhosis, Mycoplasma is rarely identified as a causative agent. Case presentation: We report the case of a 43-year-old Caucasian woman presenting with an extensive abdominal conglomerate tumor mimicking malignancy. A histologic specimen showed a xanthogranulomatous inflammation. Subsequently, Mycoplasma hominis was identified as the specific causative infectious agent using a broad-range (eubacterial) polymerase chain reaction. To the best of our knowledge, this is the first reported case of an intra-abdominal Mycoplasma infection presenting as a conglomerate tumor. Conclusion: An unusual presentation of an inflammatory process in the abdomen or an insufficient response to conventional therapy should prompt clinicians to consider atypical infectious agents in the differential diagnosis. This case illustrates the potential of newer diagnostic methods, since certain fastidious microorganisms may not be diagnosed and treated appropriately using conventional means

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
