Peritonitis primaria por streptococcus pyogenes, infección inusual en mujeres jóvenes.
2017
ANTECEDENTES: la peritonitis primaria es una entidad poco frecuente que se observa en pacientes con patología crónica. Sin embargo, cuando es causada por Streptococcus pyogenes la población más afectada son mujeres jóvenes sin antecedentes médicos, pudiendo derivar en un cuadro más grave, por ejemplo sepsis. CASO CLÍNICO: paciente de 30 años de edad que consulta por dolor abdominal severo acompañado de fiebre, con signos de irritación peritoneal y dolor a la movilización cervical. Las pruebas de imagen mostraban signos inespecíficos, sin imágenes sugerentes de perforación. Ante el cuadro de abdomen agudo se realizó una laparoscopia exploradora. El único hallazgo fue la gran cantidad de líqu…
Reproductive outcomes after hysteroscopic metroplasty for women with dysmorphic uterus and recurrent implantation failure
2019
The aim of this study was to assess the reproductive outcomes of women with recurrent implantation failure (RIF) after hysteroscopic metroplasty for dysmorphic uteri. Methods: This retrospective observational study included 190 women with a diagnosis of RIF. These patients were eligible for hysteroscopic metroplasty for dysmorphic uteri, including T-shaped uteri, between January 2008 and September 2015 at the Instituto Valenciano de Infertilidad (IVI) in Valencia, Spain. Results: The total clinical pregnancy rate, the live birth rate, and the abortion rate were 80.0% (152/190), 77.9% (147/190) and 8.9%, respectively. At 12 months, the clinical pregnancy rate was 76.3% (145/190) and at 6 mon…
Phylogenetic relationships of genus Stertomys (Gliridae) from the “Terre Rosse” fissure filling (Gargano, Apulia)
2011
Stertomys is an endemic genus of Gliridae commonly found in the Late Miocene “Terre Rosse” fissure fillings from Gargano (southern Italy). The taxonomy of this genus have been recently reconsidered and, up to date, five new species have been described beside the giant Stertomys laticrestatus Daams & Freudenthal 1985. The species have different biochronological range and may be assigned to two groups according to their size and complexity of the dental pattern. The smaller and morphologically simpler group includes Stertomys simplex Martín-Suárez & Freudenthal 2007, Stertomys daamsi Freudenthal & Martín-Suárez 2006 (occurring in the older fissures) and Stertomys degiulii Rinaldi & Masini 200…
Solar forcing for nutricline depth variability inferred by coccoliths in the pre-industrial northwestern Mediterranean
2023
The oceanic system has been rapidly changing under human-induced climate change that is taking place at unprecedented rates. The paleoclimate archive of the last two millennia is often adopted to discern the ongoing anthropogenic global warming from the pre-industrial natural climate variability. The Mediterranean Sea is an especially critical system, being particularly affected by climate change. A common group of marine unicellular planktonic calcifiers, coccolithophores, are forming calcite plates, coccoliths. When reaching the sediments, they have been employed as a proxy in many paleoenvironmental reconstructions and are increasingly used in the last centuries. Recent studies indicate …

Progression Free Survival, Overall Survival, and Relapse Rate in Endometrioid Ovarian Cancer and Synchronous Endometrial-Ovarian Endometrioid Cancer …
2022
Background and Objectives: We aimed to evaluate Progression Free Survival (PFS), Overall Survival (OS), and relapse rate in women affected by endometrioid ovarian cancer and synchronous endometrial-ovarian endometrioid cancer (SEO-EC). As secondary outcome, we assessed whether systematic pelvic and para-aortic lymphadenectomy could be considered a determinant of relapse rate in this population. Materials and Methods: We performed a retrospective analysis of women with diagnosis of endometrioid ovarian cancer or SEO-EC between January 2010 to September 2020, and calculated PFS, OS and relapse rate. Results: In almost all the patients (97.6%) who underwent systematic pelvic and para-aortic ly…

Supplementation with d-chiro-inositol in women
2023
The world of natural compounds has been investigated with the aim of discovering possible medical applications ever since the origin of medicine. Recently, the field of gynecology has developed a growing interest regarding inositols. Inositols are cyclic polyols with a key role in many metabolic pathways. Their stability throughout the evolution of life can mark these molecules as prebiotic, due to their biochemical importance. These molecules can be classified into nine stereoisomeric compounds; among them, myo-inositol (MI) is the most important and frequent form found in nature. Inositols were first discovered in 1850 by Johanes Joseph Scherer and extracted from muscle cells, the name of…
Formation of secondary carbonates and native sulphur in sulphate-rich Messinian strata, Sicily
2010
Abstract Microbially formed authigenic carbonates accompanied by native sulphur are present in the ‘Calcare Solfifero’ below a thick succession of gypsum deposited during the Messinian salinity crisis in Sicily. We sampled these carbonates and associated sulphur in five former sulphur mines to subject them to a detailed petrographic and geochemical study in order to explore their different modes of formation. Native sulphur formed in conjunction with microbial sulphate reduction, which is reflected in its depletion in 34S (δ34S values as low as − 2‰ vs. V-CDT) and an enrichment of 34S in the residual sulphate (δ34S values as high as + 61‰). The oxidation of organic matter by sulphate reduct…
La sostenibilidad y el debate nuclear
2008
Las centrales nucleares estan siendo presentadas como “solucion verde” al problema energetico, debido a que no conllevan emisiones de CO2. En este articulo se pretende poner de manifiesto que, sin embargo, esta indudable ventaja va acompanada de muy serios inconvenientes que obligan a rechazar la opcion nuclear.Palabras claves: Sostenibilidad; cambio climatico; energia nuclear; energias renovables.Sustainability and the nuclear power debateNuclear power is being presented as a “green solution” to the energetic problem, because it doesn’t generates CO2 emissions. We intend to show that this indubitable advantage does not compensates other serious inconveniences that recommend rejecting the n…
