Marinade injection of pork as a possible technological strategy to reduce boar taint: Response and attitude of the consumer.

Sensory evaluation by consumers allows validation of a solution for the food industry to overcome boar taint and market entire male pork with high levels of boar taint considered "unfit for human consumption". One possible technological strategy for improvement is the injection marination of entire male pork to help minimise the impact of boar taint and improve its marketability. The responses of 120 regular pork consumers, to entire males with high levels of boar taint and castrated pork, both injection-marinated, were evaluated. The results showed a similar response between entire and castrated male pork regardless of sex, and the detection of unpleasant odours and flavours (as farm/animal), thus offering a new alternative to the pork sector to mask the boar taint and revalue this pork. However, it was observed that consumer information on castration and animal welfare of entire male pork is scarce, and it is important to increase their knowledge so that they can place a value on this technological strategy with entire male pork and thus increase their purchase intention.

Update on the status of the contamination by organotin compounds in sediment of Nuevo Gulf, Argentina. Insights from field and experimental studies.

Organotin compounds are persistent pollutants and are considered chemicals of high environmental concern. In the present study, the distribution and degradation of tributyltin were evaluated in field sediments and through an ex situ experiment. For this, sediment samples from two locations were analysed: Luis Piedrabuena Harbour, with higher maritime traffic, and Cerro Avanzado, which receives less impact from anthropogenic activities. The results indicated that pollution levels at Luis Piedrabuena Harbour have decreased compared with studies performed 9 years ago for the same area. On the contrary, traces of organotin compounds have been found for the first time at Cerro Avanzado. Moreover, the butyltin degradation index indicated that organotin compounds undergo an advanced degradation process in the collected samples at both sites. Ex situ experiments revealed a limited capacity of sediments to retain tributyltin, and suggested an active role of bioturbation activity in the degradation of these compounds. In addition, visualisation using chemometric techniques (principal components analysis) allowed a simpler analysis of two sediment characteristics: the degree of contamination and the degradation levels of organotin compounds.

Plasma rico en plaquetas como opción terapéutica en el síndrome de la almohadilla grasa plantar / Platelet-rich plasma as a therapeutic option in heel fat pad syndrome

El síndrome de la almohadilla grasa plantar es la segunda causa de talalgia más frecuente en las consultas de Rehabilitación. Se trata de una desestructuración de la grasa plantar que conlleva la pérdida de amortiguación en la marcha y dolor plantar. Es debido a la degeneración o el traumatismo repetido que causa la alteración de la estructura de la almohadilla plantar, perdiendo su compresibilidad y función. El diagnóstico del síndrome de la grasa plantar se realiza mediante ecografía. El tratamiento se basa fundamentalmente en medidas conservadoras. Se plantea la infiltración con plasma rico en plaquetas como opción terapéutica con el objetivo de mejorar el dolor y la inflamación de la almohadilla grasa plantar. Describimos el primer caso clínico publicado de infiltración con plasma rico en plaquetas como tratamiento del síndrome de la almohadilla grasa plantar.(AU)

Heel fat pad syndrome is the second most frequent cause of heel pain at Rehabilitation services. It is a structure damage of the plantar fat that leads to loss of cushioning in gait and plantar pain. It is due to degeneration or repeated trauma that causes alteration of the structure of the foot pad losing its compressibility and function. The diagnosis of heel fat pad syndrome is made by ultrasound study. Treatment is primarily based on conservative measures. Infiltration with platelet-rich plasma is proposed as a therapeutic option with the aim of improving pain and inflammation of the plantar fat pad. We report the first published case of ultrasound-guided infiltration with platelet-rich plasma as a treatment for heel fat pad syndrome.(AU)

Trastornos de tics e impulso premonitorio: validación de la versión espñola de la «Escala para el Impulso Premonitorio al Tic» en niños y adolescentes / Tic disorders and premonitory urges: validation of the Spanish-language version of the Premonitory Urge for Tics Scale in children and adolescents

Introducción: La mayoría de personas con tics persistentes refiere notar una sensación des-agradable (impulso premonitorio) antes de sufrir un tic. En los últimos a ̃nos, el interés haciaestos fenómenos sensoriales ha aumentado debido al importante papel que tienen en la terapiade conducta. Sin embargo, los instrumentos para evaluarlos aún son escasos. Entre ellos, laEscala para el Impulso Premonitorio al Tic (Premonitory Urge for Tics Scale, PUTS) es el másutilizado. Métodos: Examinamos las propiedades psicométricas y la estructura factorial de la versiónespa ̃nola de la PUTS en una muestra de 72 ni ̃nos y adolescentes con síndrome de Tourette otrastorno de tics persistentes. Analizamos los datos para el total de la muestra y por grupos deedad (ni ̃nos hasta los 10 a ̃nos y mayores de 10 a ̃nos). Resultados: La PUTS obtuvo una buena consistencia interna y correlaciones moderadas entreítems de la escala (excepto en el ítem uno). Se encontró una buena validez divergente, unaadecuada fiabilidad test-retest y una estructura bifactorial (con una dimensión de fenómenosmentales relacionados con el trastorno obsesivo-compulsivo y otra sobre las cualidades y fre-cuencia de los impulsos premonitorios). Estos resultados se replicaron para ambos grupos deedad, excepto la validez divergente y la fiabilidad test-retest que fueron inferiores en el grupode menor edad.(AU)

Introduction: Most people with persistent tics report an unpleasant sensation (premonitoryurge) before the tic. In recent years, interest in these sensory phenomena has increased due totheir important role in behavioural therapy. However, instruments for assessing these sensationsremain scarce. Among the available instruments, the Premonitory Urge for Tics Scale (PUTS) isthe most widely used. Methods: We examined the psychometric properties and factor structure of the Spanish-language version of the PUTS in a sample of 72 children and adolescents with Tourette syndromeor persistent tic disorders. We analysed data from the total sample and by age group (childrenup to 10 years old and children/adolescents over 10). Results: The PUTS presented good internal consistency and moderate correlations betweenitems on the scale (except for item one). Divergent validity was good, test-retest reliabilitywas adequate, and a bifactorial structure was identified (one dimension related to mentalphenomena reported in obsessive-compulsive disorder, and another related to the quality andfrequency of premonitory urges). These results were replicated in both age groups, with lowerdivergent validity and test-retest reliability in the younger group.Conclusions: The Spanish-language version of the PUTS is a valid, reliable tool for assessingpremonitory urges in both children and adolescents, especially after the age of 10.(AU)

Desarrollo genital prenatal. Clasificación, diagnóstico y manejo de las anomalías de la diferenciación sexual / Prenatal genital development. Classification, diagnosis, and management of abnormalities of sexual differentiation

Revisión de la etiopatogenia y clasificación de las anomalías de la diferenciación sexual, así como del desarrollo genital prenatal, para que resulte de utilidad en la evaluación y manejo diagnóstico, mediante una búsqueda bibliográfica de la literatura más actual publicada a través de las bases de datos PubMed, MedLine, Embase, BioMed Central y SciELO. Las anomalías de la diferenciación sexual comprenden un amplio espectro de enfermedades que pueden desarrollarse en diferentes etapas de la vida. Estas anomalías requieren un manejo y evaluación compleja multidisciplinar en la que el obstetra desarrolla un papel fundamental, siendo referente en el diagnóstico prenatal de estas. La discordancia entre el sexo genético determinado por el test prenatal no invasivo y el fenotípico observado por medio de la ecografía es un hallazgo cada vez más frecuente, con una incidencia de 1 por cada 1.500-2.000 embarazos. La detección temprana de esta discordancia puede orientar la sospecha clínica y mejorar el manejo de las anomalías del desarrollo sexual desde la etapa prenatal.(AU)

To review the most current literature on the aetiopathogenesis and classification of abnormalities of sexual differentiation, as well as prenatal genital development. A literature search through PubMed, MedLine, Embase, BioMed Central, and SciELO databases was conducted. Abnormalities of sexual differentiation comprise a wide spectrum of diseases that can develop at different stages of life. These anomalies require complex evaluation by a multidisciplinary team in which the obstetrician plays a fundamental role in prenatal diagnosis. Discrepancy between the genetic sex determined by non-invasive prenatal testing and the phenotypic sex observed by ultrasound is an increasingly frequent finding, with an incidence of 1 in 1,500-2,000 pregnancies. Early detection of this discrepancy can guide clinical suspicion and improve the management of different sexual developmental anomalies from the prenatal period.(AU)

Consumer perception of entire male pork coated with spiced edible films as a new product to mask boar taint.

Pork production has undergone a shift towards the rearing of entire male pigs, however, its meat might carry with the presence of boar taint and it would be considered "unfit for human consumption". To offer a new alternative to the pork sector tailored to the needs of consumers, a viable option would be the use of edible spiced gelatin films to help minimize boar taint and improve its marketability. The responses of 120 regular meat consumers to entire pork with high levels of boar taint and castrated pork free of boar taint, both coated with spiced gelatin films were evaluated. They showed a similar response between entire and castrated male pork coated with spiced films, regardless of whether consumers usually detected unpleasant odours (as farm/animal) when consuming pork or not. Therefore, the new spiced films offer a new range of products to consumers as they contribute to the improvement of the sensory quality of entire male pork, especially among consumers who tend to buy new products.

Treatment with oral or topical sirolimus in complex vascular anomalies in pediatrics. Experience in a third-level hospital. / Tratamiento con sirolimus oral o tópico en anomalías vasculares complejas en pediatría. Experiencia en un hospital terciario.

OBJECTIVE: The use of sirolimus in vascular anomalies is a special indication not authorized in its data sheet. The objective of this study was to increase the evidence of oral or topical use of sirolimus for this indication in the pediatric population. MATERIALS AND METHODS: An observational, retrospective study of patients under 18 years of age treated with oral or topical sirolimus for vascular anomalies was carried out. Diagnosis and location of lesions, administration route and dosage of sirolimus, blood levels of sirolimus in patients who received oral treatment, treatment duration, response, and toxicity were collected. RESULTS: 18 patients - 7 with oral treatment and 11 with topical treatment - were included. With oral sirolimus, the overall response rate was 85.7%. Sirolimus was discontinued in 2 cases - as a result of full resolution and progression. 57.1% of patients had adverse effects, most of which were mild. Dyslipidemia was the most frequent adverse effect. Blood levels were monitored in all patients for dose adjustment purposes. With topical treatment, the overall response rate was 72.7%. Sirolimus was discontinued in 3 cases -due to progression in 2 cases and to stability in 1. 27.3% of patients had adverse effects, with itching standing out as the most frequent one. CONCLUSIONS: The favorable results of sirolimus treatment in our patients seem to confirm its effectiveness and safety in vascular anomalies, which make it stand as a therapeutic option in pediatric patients. However, further research is required to establish the optimal treatment regimen, treatment duration, and potential long-term adverse effects.

A Methodology Based on Machine Learning and Soft Computing to Design More Sustainable Agriculture Systems.

Advances in new technologies are allowing any field of real life to benefit from using these ones. Among of them, we can highlight the IoT ecosystem making available large amounts of information, cloud computing allowing large computational capacities, and Machine Learning techniques together with the Soft Computing framework to incorporate intelligence. They constitute a powerful set of tools that allow us to define Decision Support Systems that improve decisions in a wide range of real-life problems. In this paper, we focus on the agricultural sector and the issue of sustainability. We propose a methodology that, starting from times series data provided by the IoT ecosystem, a preprocessing and modelling of the data based on machine learning techniques is carried out within the framework of Soft Computing. The obtained model will be able to carry out inferences in a given prediction horizon that allow the development of Decision Support Systems that can help the farmer. By way of illustration, the proposed methodology is applied to the specific problem of early frost prediction. With some specific scenarios validated by expert farmers in an agricultural cooperative, the benefits of the methodology are illustrated. The evaluation and validation show the effectiveness of the proposal.

Heel fat pad syndrome is the second most frequent cause of heel pain at Rehabilitation services. It is a structure damage of the plantar fat that leads to loss of cushioning in gait and plantar pain. It is due to degeneration or repeated trauma that causes alteration of the structure of the foot pad losing its compressibility and function. The diagnosis of heel fat pad syndrome is made by ultrasound study. Treatment is primarily based on conservative measures. Infiltration with platelet-rich plasma is proposed as a therapeutic option with the aim of improving pain and inflammation of the plantar fat pad. We report the first published case of ultrasound-guided infiltration with platelet-rich plasma as a treatment for heel fat pad syndrome.

Tic disorders and premonitory urges: validation of the Spanish-language version of the Premonitory Urge for Tics Scale in children and adolescents.

INTRODUCTION: Most people with persistent tics report an unpleasant sensation (premonitory urge) before the tic. In recent years, interest in these sensory phenomena has increased due to their important role in behavioural therapy. However, instruments for assessing these sensations remain scarce. Among the available instruments, the Premonitory Urge for Tics Scale (PUTS) is the most widely used. METHODS: We examined the psychometric properties and factor structure of the Spanish-language version of the PUTS in a sample of 72 children and adolescents with Tourette syndrome or persistent tic disorders. We analysed data from the total sample and by age group (children up to 10 years old and children/adolescents over 10). RESULTS: The PUTS presented good internal consistency and moderate correlations between items on the scale (except for item 1). Divergent validity was good, test-retest reliability was adequate, and a bifactorial structure was identified (one dimension related to mental phenomena reported in obsessive-compulsive disorder, and another related to the quality and frequency of premonitory urges). These results were replicated in both age groups, with lower divergent validity and test-retest reliability in the younger group. CONCLUSIONS: The Spanish-language version of the PUTS is a valid, reliable tool for assessing premonitory urges in both children and adolescents, especially after the age of 10.

Assessment of single-nucleotide variant discovery protocols in RNA-seq data from human cells exposed to mycotoxins.

Food and feed contamination by nonlegislated mycotoxins beauvericin (BEA) and enniatin B (ENB) is a worldwide health concern in the present. The principal objective of this work is to assess some of the existing protocols to discover the single nucleotide variants (SNVs) in transcriptomic data obtained by RNA-seq from Jurkat cells in vitro samples individually exposed to BEA and ENB at three concentration levels (1.5, 3 and 5 µM). Moreover, previous transcriptomic results will be compared with new findings obtained using a different protocol. SNVs rs201003509 in BEA exposed cells and the rs36045790 in ENB were found in the differentially expressed genes in all doses compared to controls by means of the Genome Analysis Toolkit (GATK) Best Practices workflow. SNV-RNA-seq complementary pipeline did not show any SNV. Concerning gene expression, discrepant results were found for 1.5 µM BEA exposed cells compared with previous findings. However, 354 overlapped differentially expressed genes (DEGs) were identified in the three ENB concentrations used, with 147 matches with respect to the 245 DEGs found in the previous results. In conclusion, the two discovery SNVs protocols based on variant calling from RNA-seq used in this work displayed very different results and there were SNVs found manually not identified by any pipeline. Additionally, the new gene expression analysis reported comparable but non identical DEGs to the previous transcriptomic results obtained from these RNA-seq data.

Increased functional activity, bottom-up and intrinsic effective connectivity in autism.

Sensory perceptual alterations such as sensory sensitivities in autism have been proposed to be caused by differences in sensory observation (Likelihood) or in forming models of the environment (Prior), which result in an increase in bottom-up information flow relative to top-down control. To investigate this conjecture, we had autistic individuals (AS) and neurotypicals (NT) perform a decision-under-uncertainty paradigm while undergoing functional magnetic resonance imaging (fMRI). There were no group differences in task performance and in Prior and Likelihood representations in brain activity. However, there were significant group differences in overall task activity, with the AS group showing significantly greater activation in the bilateral precuneus, mid-occipital gyrus, cuneus, superior frontal gyrus (SFG) and left putamen relative to the NT group. Further, when pooling the data across both groups, we found that those with higher AQ scores showed greater activity in the left cuneus and precuneus. Effective connectivity analysis using dynamic causal modelling (DCM) revealed that group differences in BOLD signals were underpinned by increased activity within sensory regions and a net increase in bottom-up connectivity from the occipital region to the precuneus and the left SFG. These findings support the hypothesis of increased bottom-up information flow in autism during sensory learning tasks.

Early transcranial direct current stimulation with modified constraint-induced movement therapy for motor and functional upper limb recovery in hospitalized patients with stroke: A randomized, multicentre, double-blind, clinical trial.

BACKGROUND: Constraint-induced movement therapy (CIMT) and transcranial direct current stimulation (tDCS) are used to reduce interhemispheric imbalance after stroke, which is why the combination of these therapies has been used for neurological recovery, but not in the acute phase. OBJECTIVES: To evaluate the effectiveness of combining active or sham bihemispheric tDCS with modified CIMT (mCIMT) for the recovery of the Upper Limb (UL) in hospitalized patients with acute and subacute stroke. METHODS: This randomized controlled, double-blind, placebo-controlled, parallel group clinical trial was executed between September 2018 to March 2021 recruited 70 patients. The patients were randomized to one of two groups to receive treatment for 7 consecutive days, which included 20 min of active or sham bihemispheric tDCS daily (anodal ipsilesional and cathodal contralesional), with an mCIMT protocol. The primary outcome was the difference in the evolution of motor and functional upper limb recovery with assessment on days 0, 5, 7, 10 and 90. The secondary outcomes were independence in activities of daily living (ADL) and quality of life. RESULTS: The active group presented a statistically significant gap compared to the simulated group throughout the trend in the scores of the FMA (motor function and joint pain) and WMFT (functional ability and weight to box) (p < 0.05) and showed a minimal clinically important difference (FMA: difference between groups of 4.9 points [CI: 0.007- 9.799]; WMFT: difference between groups of 6.54 points [CI: 1.10-14.15]). In the secondary outcomes, there was a significant difference between the groups in ADL independence (Functional Independence Measure: difference of 8.63 [CI: 1.37-18.64]) and perceived recovery of quality of life evaluated at 90 days (p = 0.0176). CONCLUSIONS: Combining mCIMT with bihemispheric tDCS in patients hospitalized with acute-subacute stroke allows us to maximize the motor and functional recovery of the paretic upper limb in the early stages and independence in ADL, maintaining the effects over time.

One-Pot Synthesis of MnOx-SiO2 Porous Composites as Nanozymes with ROS-Scavenging Properties.

The development of nanomaterials that mimic the activity of enzymes is a topic of interest, for the decomposition of reactive oxygen species (ROS). We report the preparation of a novel nanocomposite of MnOx needles covered with SiO2 porous material. The material was prepared in one pot with a two-step procedure. The material was characterized by EDX, SEM, TEM, XRD, nitrogen adsorption-desorption isotherms, and XPS. The synthesis protocol took advantage of the atrane method, favoring the nucleation and initial growth of manganese oxide needles that remained embedded and homogeneously dispersed in a mesoporous silica matrix. The final composite had a high concentration of Mn (Si/Mn molar ratio of ca. 1). The nanozyme presented bimodal porosity: intraparticle and interparticle association with the surfactant micelles and the gaps between silica particles and MnOx needles, respectively. The porosity favored the migration of the reagent to the surface of the catalytic MnOx. The nanozyme showed very efficient SOD and catalase activities, thus improving other materials previously described. The kinetics were studied in detail, and the reaction mechanisms were proposed. It was shown that silica does not play an innocent role in the case of catalase activity, increasing the reaction rate.

Tratamiento rehabilitador de la infección por COVID: caracterización y seguimiento de pacientes hospitalizados en Granada, España / Rehabilitation and COVID disease: characterization and follow-up of hospitalized patients in Granada, Spain

Objetivo: Caracterización de una muestra de pacientes hospitalizados por complicaciones de la infección COVID-19 con atención a potenciales determinantes pronósticos de su evolución e impacto del tratamiento rehabilitador en el desempeño funcional, motor y respiratorio. Método: Estudio descriptivo, retrospectivo, longitudinal de una cohorte de pacientes ingresados con diagnóstico de COVID-19 que requirieron tratamiento rehabilitador en el Hospital Universitario Virgen de las Nieves de Granada desde marzo a junio de 2020, evaluados al ingreso, alta y a los tres meses mediante escalas de condición física (IFIS), valoración funcional: general (Rankin, Barthel), respiratoria (mMRC, BORG) y marcha (FAC). Resultados: Se incluyeron 30 pacientes, edad media 62,8 (54-70) años, 80% alguna comorbilidad: hipertensión 66,7%, obesidad 36,7%, diabetes 33,3%. Estancia hospitalaria media de 45,4 días, 86,7% requirió Unidad de Cuidados Intensivos (UCI) (29,1 días), de ellos 76,7% ventilación mecánica. El 86,7% de los pacientes presentaron alguna complicación, siendo mayor la polineuropatía/miopatía del paciente crítico (83,3% de los pacientes). Al alta, un 80% requirió ayuda para caminar. El índice de funcionalidad mostró una evolución en «U» al ingreso, alta y a los tres meses (Barthel 93,8; 60,0; 91,6, respectivamente). Se encontró un mayor deterioro funcional (Barthel < 60) en pacientes hombres, enfermedad pulmonar obstructiva crónica (EPOC), hipertensión arterial (HTA), obesidad y proteína C reactiva (PCR) elevada al ingreso y evolución más favorable en aquellos con dímero D y linfocitos más elevados al ingreso.ConclusiónLos ingresos hospitalarios por COVID-19 implican complicaciones a nivel funcional, respiratorio y de la marcha mayoritariamente graves pero reversibles parcialmente a los tres meses con tratamiento rehabilitador. Se describen factores potencialmente pronósticos que merecen estudios prospectivos.(AU)

Objective: The characterization of a sample of patients hospitalized with complications of the COVID-19 infection regarding potential prognostic factors, clinical evolution, and impact of rehabilitation treatment on functional, motor, and respiratory outcomes. Method: Descriptive, retrospective, longitudinal study of a cohort of patients under rehabilitation treatment admitted at Virgen de las Nieves University Hospital in Granada from March to June 2020, assessed upon admission, discharge and at 3 rd month using physical condition scales (IFIS) and functional assessment: general (Rankin, Barthel), respiratory (mMRC, BORG) and gait (FAC). Results: 30 patients with a mean age of 62.8 (54-70) years were included, 80% with comorbidity: hypertension 66.7%, obesity 36.7%, diabetes 33.3%. The mean hospital stay was 45.4 days, with 86.7% requiring ICU (29.1 days) and 76.7% of them required mechanical ventilation. An 86.7% of the patients presented with complications, mostly with polyneuropathy-myopathy of the critical patient (83.3%). At discharge, 80% required walking assistance. The functionality index showed a “U”-evolution at admission, discharge and at 3 rd month (Barthel 93.8; 60.0; 91.6 respectively). A greater functional decline (Barthel < 60) was found in male patients, COPD, HT, obesity, and elevated protein C reactive at admission; and a more favourable evolution in those with elevated D-dimer and lymphocyte values upon admission. Conclusión: Hospital admission for COVID-19 patients involve complications at the functional, respiratory and gait levels that are mostly serious but partially reversible at 3 months with rehabilitation treatment. Potential prognostic factors are described and deserve prospective studies.(AU)

Immune surveillance for six vaccinable pathogens using paired plasma and dried blood spots in HIV infected and uninfected children in Kinshasa.

Child vaccination reduces infant mortality rates. HIV-infected children present higher risk of diseases than non-infected. We report the protection coverage rates for 6 vaccine-preventable diseases in a paediatric population from the Democratic Republic of the Congo (DRC) and the impact of HIV infection, providing the first data on the validity of dried blood samples (DBS) to monitor the immune protection. During 2016-2018 DBS from 143 children/adolescents were collected in Kinshasa (DRC), being 52 HIV-infected. Forty-two had a paired plasma sample. Protective IgG was quantified (VirClia-IgG,VIRCELL) to obtain the optimal cut-off in IgG detection in DBS. ROC curves were generated with R software and statistical analyses with Stata. Protective IgG levels varied across pathogens, not reaching herd immunity. HIV-infected presented lower vaccine protection than uninfected for all analyzed pathogens, except rubella, with statistically significant differences for measles (30.8% vs. 53.8%; p = 0.008) and tetanus (3.8% vs. 22%; p = 0.0034). New cut-offs were calculated when using DBS to improve test performance. We reinforce the necessity to increase pediatric vaccination coverage in Kinshasa, especially in HIV seropositive, with less capacity to maintain adequate antibody levels. DBS were useful to monitor vaccination coverage in seroprevalence studies in resource-limited settings, after optimizing the cut-off value for each pathogen.

Hiperplasia endotelial papilar intravascular (tumor Masson) de localización ginecológica / Intravascular papillary endothelial hyperplasia (Masson's tumour) of gynaecological origin

La hiperplasia papilar endotelial intravascular o tumor de Masson es una lesión vascular no neoplásica de carácter reactivo. Se caracteriza por ser un tumor poco frecuente, clínicamente inespecífico y con localizaciones descritas muy diversas. Resulta fundamental tenerlo en consideración dentro del diagnóstico diferencial de los tumores vasculares malignos como el angiosarcoma, cuyo pronóstico es muy diferente. Para lograr su diagnóstico definitivo el estudio anatomopatológico resulta primordial. El tratamiento de elección es la exéresis quirúrgica asegurando márgenes libres de enfermedad. El presente caso reportado supone un hecho excepcional, al ser un tumor de Masson de localización pélvica, cuyo diagnóstico fue un hallazgo casual propiciado por el estudio de estadificación quirúrgica de un adenocarcinoma de ovario.

Intravascular papillary endothelial hyperplasia or Masson's tumour is a non-neoplastic vascular lesion of reactive character. It is a rare diagnosis, clinically non-specific and with diverse locations. It is essential to take it into consideration and make a differential diagnosis with malignant vascular tumours such as angiosarcoma. Pathological study is fundamental for diagnosis. Treatment consists of complete resection of the tumour, including sufficiently wide margins to avoid recurrence.The case reported is an exceptional event, because of the pelvic location of the Masson's tumour that was diagnosed as part of the surgical staging of an ovarian cancer.

Debut y manejo de leucemia mieloblástica aguda durante la gestación: a propósito de un caso / Debut and management of acute myeloblastic leukaemia during pregnancy: a case report

La leucemia mieloide aguda (LMA) es una de las neoplasias hematológicas más mortales. Durante el embarazo es una complicación rara, que puede dar resultados adversos, como la muerte, sin tratamiento adecuado. El manejo de la LMA durante el embarazo sigue siendo un desafío. Presentamos el caso de una mujer primigesta de 34 años con 18 semanas de gestación que acudió a Urgencias por cuadro de dolor e hipertrofia de mucosa oral, acompañado de astenia intensa. Se diagnóstico leucemia mieloblástica aguda (LAM-M4). Se ofertó posibilidad de interrumpir la gestación, dada la poca evidencia referente a la evolución materno-fetal, que la paciente rechazó, por lo que se inició tratamiento quimioterápico. En los controles ecográficos no se evidenciaron alteraciones teratogénicas; el crecimiento fetal tuvo parámetros normales, sin alteraciones en los valores del flujo Doppler. Se decidió finalizar gestación a las 32 semanas y tres días. Nació un varón pretérmino mediante parto eutócico con test de Apgar y pH de cordón umbilical normales, sin precisar reanimación. El puerperio fue favorable y a los 15 días del alta ingresó para un trasplante de médula ósea de su hermana, HLA idéntica. La paciente finalmente falleció por rechazo del trasplante y las complicaciones derivadas de este suceso.

Acute myeloid leukaemia (AML) is one of the deadliest haematological malignancies. During pregnancy it is a rare comorbidity and can lead to adverse outcomes, such as death, without adequate treatment. The management of AML during pregnancy remains a challenge. We report the case of a primigravida 34-year-old, with 18 weeks of amenorrhoea, who attended the emergency department presenting with pain and hypertrophy of the oral mucosa, accompanied by intense asthenia. Acute myeloblastic leukaemia was diagnosed. The possibility of terminating the pregnancy was offered given the lack of evidence regarding the maternal-foetal outcome, but the patient rejected it, so chemotherapy treatment was started. In the ultrasound controls there was no evidence of teratogenic alterations nor foetal growth restriction, and there were no alterations in Doppler flow values. It was decided to end the pregnancy at 32+3 GW. A preterm male was born through eutocic delivery with a normal Apgar test and umbilical cord pH, and did not require resuscitation. The puerperium was favourable and 15 days following discharge she was admitted for a bone marrow transplant from her HLA identical sister. The patient died due to rejection of the transplant and the complications derived from this event.
