A case report of uterine leiomyosarcoma: unusual clinical presentation with unilateral hydronephrosis and importance of an appropriate diagnosis.

Uterine leiomyosarcoma is a rare malignant gynecologic tumor that arises from the myometrial or endometrial stromal precursor cells. This tumor has the highest prevalence in the pre- and post-is more frequent between 40 and 60 years old. It has a very unfavorable prognosis: only early-stage tumors have an acceptable prognosis; unfortunately, it is often diagnosed accidentally, typically on an advanced stage, when hematological metastases have already spread.

Current and future methods for embryo selection: on a quest for reliable strategies to reduce time to pregnancy.

Introduction: The aim of this study was to analyze the usefulness of the principal embryological strategies to reduce time to pregnancy.

Evidence Acquisition: A systematic search of publications in the PubMed/MEDLINE, Embase and Scopus databases from inception to present including "IVF," "blastocyst," "embryo colture," "competent embryo," "time to pregnancy," "aneuploid," "euploid," "vitrification," "preimplantation genetic," "IVF strategies" and "embryo selection" alone or in combinations has been done.

Evidence Synthesis: We have selected 230 articles and 9 of them have been included in this mini-review.

Variations in coralligenous assemblages from local to biogeographic spatial scale.

The present study aims at contributing to the knowledge of the spatial variability of coralligenous reefs through the evaluation of patterns ranging from local to biogeographic scale around the island of Sardinia. The coralligenous reef assemblages of six areas were studied through a hierarchical sampling design: three sites per area were selected, in each site three plots were sampled and in each plot ten photographic samples were collected. The structure of coralligenous reefs across closed biogeographic regions is described, highlighting that nearly pristine assemblages, although characterized by similar high diversity, can be either dominated by animals, such as gorgonians and bryozoans, or macroalgae.

Extreme events and conservation of subtidal habitats: Effects of a rainfall flood on coralligenous reefs.

The increase of the intensity and frequency of rainfall-dominated flood is considered a main effect of climate change. The present study evaluated the effect of a rainfall flood event on coralligenous reefs. The flooded site was compared to three control sites using a Before/After-Control/Impact (BACI) design.

Psychopathology and personality in problematic internet users.

Few studies have addressed the issue of psychopathology and personality of individuals with problematic use of internet. In this study we research psychopathological symptoms, personality traits and predictive variables associated with problematic internet use. The study was conducted on a total of 343 students from four Italian Universities using Pathological Internet Use Scale, Big Five Questionnaire, and Symptom Check List 90 Revised.
