Síndrome de ovario remanente. Revisión bibliográfica. Evidencia actual / Ovarian remnant syndrome. Literature review. The latest evidence

El síndrome de ovario remanente supone la persistencia de corteza ovárica por su resección incompleta, principalmente tras ooforectomía o anexectomía. Es una entidad infradiagnosticada que afecta de forma importante a las pacientes. Se produce principalmente en endometriosis, enfermedad pélvica inflamatoria o cirugías reiteradas. Nuestro objetivo es revisar la evidencia disponible para determinar su forma de presentación, diagnósticos diferenciales, tratamiento y estrategias preventivas. Para ello, hemos realizado una búsqueda bibliográfica de literatura a través de PubMed, Medline, Embase, BioMed Central y SciELO. Concluimos en que esta patología se debe incluir en el diagnóstico diferencial en pacientes con dolor pélvico crónico que hayan sido intervenidas de ooforectomía. Su tratamiento es principalmente quirúrgico, siendo la laparoscopia el gold standard al permitir una mayor exposición anatómica, menor pérdida sanguínea, estancia hospitalaria y tasa de complicaciones. El aislamiento en el espacio retroperitoneal del ligamento infundíbulo-pélvico durante la ooforectomía es la principal maniobra para prevenir su aparición.(AU)

Remnant ovarian syndrome is the persistence of ovarian cortex after a deficient resection, mainly after oophorectomy. It is a misdiagnosed condition that significantly affects patients. It is typical from endometriosis, pelvic inflammatory disease or previous multiple surgeries. Our objectives are to review the current evidence to determine clinic features, differential diagnosis, treatment and preventive strategies. For this, we have carried out a bibliographic literature search through the PubMed, Medline, Embase, BioMed Central and SciELO databases.We conclude that this pathology should be included in the differential diagnosis in patients with chronic pelvic pain who have undergone oophorectomy. Its treatment is surgical, being the laparoscopic approach the gold standard. It allows a better anatomic exposure, with lower blood loss, complication rate and hospital stay. Isolating the infundibulopelvic ligament in the retroperitoneal space during the oophorectomy is the main strategy to prevent this complication.(AU)

¿Es la nacionalidad de la paciente un factor influyente en el proceso de embarazo, parto y puerperio? / Does the nationality of the patient have an influence on the process of pregnancy, childbirth and post-partum?

Objetivo: Determinar si la nacionalidad de la paciente es un factor que influye en el seguimiento de la gestación, en las características del parto o en las complicaciones posteriores durante el puerperio. Material y métodos: Estudio observacional retrospectivo en el que se han recogido todos los partos registrados en el Hospital Universitario Virgen Macarena de Sevilla durante un periodo de 5 meses. La muestra se ha dividido en 2cohortes de estudio, una conformada por las pacientes de nacionalidad española y otra por las pacientes extranjeras. Resultados: Se registraron los datos de 1.259 gestantes (1.135 españolas y 124 extranjeras). El número de visitas y pruebas prenatales fue mayor en la cohorte de pacientes españolas. El porcentaje de inducciones fue mayor en las pacientes españolas (22,1%); sin embargo, el porcentaje de partos eutócicos fue superior en las gestantes extranjeras, con igualdad (23,4%) respecto a la tasa de cesáreas entre ambas cohortes. La tasa de desgarros y el porcentaje de partos sin epidural fue mayor en las pacientes extranjeras, mientras que la tasa de episiotomías fue menor. Por último, el porcentaje de enfermedad gestacional y complicaciones puerperales fue mayor en las gestantes españolas, con un porcentaje ligeramente inferior de complicaciones del recién nacido respecto a las pacientes extranjeras. Conclusiones: Nuestros resultados determinan que si bien el seguimiento del embarazo es más exhaustivo en las pacientes españolas, algunas variables como la tasa de inducción, parto instrumental, episiotomía o el porcentaje de pacientes que solicitan analgesia epidural son menores en la población extranjera.(AU)

Objective: To determine whether the nationality of the patient is a factor that influences pregnancy follow-up, labour characteristics, and subsequent complications during post-partum. Material and methods: An observational retrospective study was performed that included every delivery registered in Macarena Hospital in Seville during a 5 months period. The sample was divided into 2cohorts, one including Spanish patients, and the other including foreign patients. Results: Data from 1259 pregnant women (1135 Spanish and 124 foreigners) were registered. The number of visits and prenatal test was greater in the Spanish cohort. The rate of labour induction was higher among Spanish patients (22.1%). However, normal vaginal delivery rate was higher among foreign pregnant women. Caesarean section rate was equal (23.4%) between both cohorts. Tearing rate and non-epidural delivery was higher among foreign patients, while episiotomy rate was lower. Gestational disorders and complications post-partum were higher in the Spanish cohort, with a slightly lower percentage of newborn complications compared to the foreign cohort. Conclusions: Our results show that pregnancy follow-up is more exhaustive among Spanish patients, but some variables such as rate of labour induction, assisted birth, episiotomy, or patients demanding epidural analgesia were lower among the foreign population.(AU)

Multistimuli Response Micro- and Nanolayers of a Coordination Polymer Based on Cu2 I2 Chains Linked by 2-Aminopyrazine.

A nonporous laminar coordination polymer of formula [Cu2 I2 (2-aminopyrazine)]n is prepared by direct reaction between CuI and 2-aminopyrazine, two industrially available building blocks. The fine tuning of the reaction conditions allows obtaining [Cu2 I2 (2-aminopyrazine)]n in micrometric and nanometric sizes with same structure and composition. Interestingly, both materials show similar reversible thermo- and pressure-luminescent response as well as reversible electrical response to volatile organic solvents such as acetic acid. X-ray diffraction studies under different conditions, temperatures and pressures, in combination with theoretical calculations allow rationalizing the physical properties of this compound and its changes under physical stimuli. Thus, the emission dramatically increases when lowering the temperature, while an enhancement of the pressure produces a decrease in the emission intensity. These observations emerge as a direct consequence of the high structural flexibility of the Cu2 I2 chains which undergo a contraction in CuCu distances as far as temperature decreases or pressure increases. However, the strong structural changes observed under high pressure lead to an unexpected effect that produces a less effective CuCu orbital overlapping that justifies the decrease in the intensity emission. This work shows the high potential of materials based on Cu2 I2 chains for new applications.
