Full textEn la experiencia clínica, los foniatras y logopedas especializados en trastornos de la voz han afirmado que las disfonías tienen relación con la personalidad del paciente. Estudios previos de Roy y Bless indican una relación entre los rasgos de personalidad neuroticismo y extroversión, definidos por Eysenck, y las disfonías funcionales y los nódulos vocales. Estos estudios proponen que las teorías de Gray pueden explicar esta relación. Gray propone la existencia de dos sistemas biológicos de activación y de inhibición conductual que responden a una mayor sensibilidad del sujeto a las recompensas y los castigos, respectivamente. En 2011, Torrubia et al. presentaron un cuestionario para la valoración de estos dos sistemas. Partiendo de los trabajos de Roy y Bless, el estudio que presentamos pretende aportar evidencias sobre la influencia de los rasgos de personalidad en la presencia de alteraciones de la voz. Se han administrado los cuestionarios EPQ-RS de Eysenck y SCSRQ de Torrubia a un grupo experimental de 141 pacientes atendidos por alteraciones de la voz y a un grupo control de 99 personas sin alteraciones vocales. A todos ellos se les administró también el cuestionario Voice Handicap Index-10 y se recogieron diversas muestras de su voz que fueron analizadas con el programa MDVP para la obtención del parámetro Dysphonia Severity Index descrito por Wuyts, y fueron valoradas con el parámetro Grade del GRBAS de Hirano por cinco logopedas expertos en alteraciones vocales. Los resultados han sido analizados con el paquete estadístico PASW 18. Los resultados muestran diferencias estadísticamente significativas entre el grupo experimental y el grupo control en relación al rasgo neuroticismo en el test EPQ (z = 6.951; p< .01) y en relación a la sensibilidad al castigo en el test SCSRQ (z = 2.207; p< .05). Los datos muestran también diferencias estadísticamente significativas entre los dos grupos con respecto a los valores del DSI (z = 9.320, p < .01). Para esta medida se ha establecido un valor de corte, con la curva ROC, en la puntuación 3.7. También se han obtenido diferencias significativas en las puntuaciones totales del VHI-10 (z = 10.351; p< .001) y un valor de corte de 7. El parámetro G ha presentado diferencias significativas (z = 10.959; p< .001) y un valor de corte en la puntuación 1. Las tres mediciones de la disfonía correlacionan con los resultados de los cuestionarios de personalidad para los rasgos neuroticismo (DSI rs = -.437, p>.001; VHI-10 rs = .416, p>0.001; parámetro G rs = .446, p>0.001) y sensibilidad al castigo (VHI-10 rs = .231, p>.01; parámetro G rs = .144, p>.05). Los resultados confirman las informaciones aportadas por investigaciones anteriores respecto a la influencia del neuroticismo en la disfonía. En el mismo sentido, podemos concluir que el rasgo introversión está más presente en la población con alteraciones de la voz. Los resultados de la escala de sensibilidad al castigo permiten pensar que las teorías de Gray pueden orientar sobre los factores emocionales en las alteraciones vocales. Asimismo, los resultados permiten concluir que los instrumentos de medida de la calidad vocal son fiables, complementarios y válidos para la discriminación de personas que sufren alteraciones de la voz.
In clinical experience, phoniatricians and speech therapists who specialize in voice disorders have argued that dysphonia is related to the patient's personality. Previous studies by Roy and Bless indicate a relationship between the personality traits neuroticism and extraversion, defined by Eysenck, and functional dysphonia and vocal nodules. These studies suggest that Gray's theories can explain this relationship. Gray proposes the existence of two biological systems of activation and behavioral inhibition, which respond to increased sensitivity of the subject to reward and punishment, respectively. In 2011, Torrubia et al. presented a questionnaire for the assessment of these two systems. Based on the work of Roy and Bless, the study presented aims to provide evidence on the influence of personality traits in the presence of voice disorders. Administered questionnaires were Eysenck's EPQ-RS and SCSRQ of Torrubia to an experimental group of 141 patients with voice disorders and a control group of 99 people with no vocal alterations. All of them answered the Voice Handicap Index-10 questionnaire and several samples of their voices were analyzed with the MDVP program so as to obtain Dysphonia Severity Index parameter described by Wuyts. These samples were evaluated with the parameter Grade of Hirano’s GRBAS by five speech pathologists specialized in voice disorders. The results were analyzed using the statistical package PASW 18. The results showed statistically significant differences between the experimental and control groups in relation to trait neuroticism on the EPQ test (z = 6951, p <.01) and in relation to sensitivity to punishment in SCSRQ test (z = 2207; p <.05). The data also showed statistically significant differences between the two groups regarding DSI values (z = 9320, p <.01). For this measure cutoff with ROC curve has been established in the score 3.7. Significant differences were also obtained in total scores of HIV-10 (z = 10,351, p <.001) and a cutoff value of 7. The parameter G has presented significant differences (z = 10,959, p <.001) and a cutoff in the score 1. All three measures of dysphonia correlated with the results of the questionnaires of personality traits neuroticism (r = -. 437 DSI, p> .001; VHI-10 r = .416, p> .001; parameter G r = .446, p <.001) and sensitivity to punishment (VHI-10 r = .231, p> 0.01; parameter G r = .144, p> .05). The results confirm the information provided by previous research on the influence of neuroticism in dysphonia. Also, we can conclude that introversion trait is more present in people with voice disorders. The relationship between the results of the sensitivity scale to punishment suggests that Gray's theories can shed some light on emotional factors in voice disorders. Finally, the results suggest that measurement instruments used for voice quality are reliable, complementary and valid for the discrimination of people with voice disorders.

Full textIntroduction: Parkinson’s disease (PD) is the second most frequent neurodegenerative disease. In the last years, interest has grown about non motor symptoms or motor symptoms without dopaminergic treatment response and a great effect in quality of life of PD patients, Oropharingeal dysphagia is very prevalent in neurodegenerative disorders and the mean cause of death in Parkinson’s patients. Its natural history and dopaminergic response is not completely understood. Deglutition implies sensitive oropharyngeal afference, Central nervous system structures and motor efferences, allowing a correct oropharingeal motor response (OMR), that means, the correct change from respiratory configuration to the digestive one. For diagnosis, we can use clinical exploration methods like Volumen-Viscosity Swallow Test or objective explorations as Videofluoroscopy, the gold-standard, that allows the detection of safety or efficacy impairment signs and the timing, velocity and forces of OMR. Speech impairment is present very early in the disease progression and shares with deglutition many central mecanisms and motor structures. Handwriting, also ivery early mpaired in the disease evolution has an excelent response to dopaminergic treatment. Objectives: Caracterization of clinical and videofluoroscopic signs of dysphagia in PD in early stages of the disease and its relation with progression, voice impairment and response of deglutition and voice impairment to dopaminergic treatment. Determining if some voice parameters can be related to dysphagia in PD. Determining if handwriting features can be good of dopaminergic treatment response. marcadores Methods: Epidemiologic and progression features of 40 PD patients, stages 1-3 of the Hoehn and Yahr score, were collected. V-VST, videofluoroscopy, voice recorders before and after swallowing and handwriting samples were also collected 12 ours after the last night dose of dopaminergic treatment and 90 minutes after the first dose in the morning. Results: V-VST and videofluoroscopy showed a very high prevalence of efficacy impairment and not so high of security without any significant dopaminergic effect. Acoustic parameters selected are frequently impaired in this patients, but also without any significant dopaminergic effect. Changes obeserved after swallowing don’t have any relation with dysphagia parameters Handwriting showed very significant changes under dopaminergic treatment effect. Conclusions: PD patients in 1-3 Hoehn and Yahr stage showed a very high prevalence of efficacy impairment and not so frequent of security without dopaminergic treatment effect, and also without progression features relation. Acoustic features studied showed changes in early phases of the disease without significant changes under dopaminergic treatment and without dysphagia relation. Some handwriting features showed a dramatic response to dopaminergic treatment .

Full textEn esta tesis doctoral se describe inicialmente una base teórica de la anatomía respiratoria en la cual se detallan los diferentes órganos por donde circula el aire, tanto de las vías circulatorias externas (la boca, la nariz, la faringe y la laringe) como de las internas (la tráquea, los bronquios y ya finalmente los pulmones). Seguidamente se explica la fisiología respiratoria y ventilatoria, dondeel diafragma es el protagonista con los diferentes tipos de ventilación que existen: la clavicular, la diafragmática, la costoabdominal y la total, entre otros. Se sigue describiendo la anatomía de la voz. El aparato fonador humano se centra especialmente en la laringe y los pliegues vocales. Posteriormente se define la fisiología de la voz: la fonación. En ella se describen los mecanismos necesarios para que se produzca la voz y aquí definimos claramente la interrelación que tienen los aparatos respiratorio y fonador. Después se hace una descripción detallada de la voz y de todas sus cualidades y características (la intensidad, el tono, el timbre, la impostación, la proyección y la articulación).Seguimos con un análisis acústico y aerodinámico de la voz y una evaluación exhaustiva de las relaciones que pueda haber de la misma con el mundo emocional. En una segunda parte se explica y se justifica el proceso empírico basado en tres instrumentos: entrevistas a expertos que nos acercan a comprender las evidencias que existen en el tema, una encuesta a través de internet sobre los posibles impactos no verbales de la voz en el mundo empresarial y finalmente un tercer instrumento consistente en una encuesta basada en diez voces consideradas modelo que se pasa a diez personas de cinco años de edad, las cuales responden una prueba de Likert estudiándose posteriormente los resultados. Finalmente se extraen conclusiones y se determinan las voces con mayor impacto emocional así como sus posibles aplicaciones. Cerramos esta tesis concluyendo que sí existe un modelo de voz que puede mejorar el rendimiento comunicativo empresarial, evidenciado a través de los diferentes instrumentos que se han utilizado en el presente trabajo, antes mencionados. Nos decantamos, según estas evidencias, por un discurso con un tempo bastante ágil, sin demasiadas pausas y que incluye inflexiones tonales, con una prosodia rica en tonalidades, con un volumen bastante moderado y sin influencia por parte del género, aunque en este último caso puede tener excepciones ligadas al contexto.
This doctoral thesis initially describes a theoretical basis of the respiratory anatomy into the different organs through the air circulates, from the external circulatory pathways (the mouth, the nose, the pharynx and the larynx)and the internal ones (the trachea, the bronchus and finally the lungs). The respiratory and ventilatory physiology are explained below, where the diaphragm is the protagonist, with the different types of ventilation that exist: clavicular, diaphragmatic, cost-abdominal and total, among others. The anatomy of the voice is still described, the human vocal apparatus is especially focused on the larynx and vocal folds. Subsequently we define the physiology of the voice: the phonation. It describes the mechanisms necessary for the voice to occur and here we clearly define the interrelation of the respiratory and speech apparatus. Afterwards a detailed description of the voice and of all its qualities and characteristics (the intensity, the tone, the timbre, the imposition, the projection and the articulation). We proceed with an acoustic and aerodynamic analysis of the voice and an exhaustive evaluation of the relationships that may exist with the emotional world. A second part explains and justifies the empirical process based on three instruments: interviews with experts that bring us closer to the evidence that exists in the subject, an online survey on the possible non-verbal impacts of voice in the world Business and finally a third instrument consisting of a survey based on ten voices considered a model that is passed to ten people of five years of age, who answer to a Likert test and then study the results. Finally conclusions are drawn and the voices with the greatest emotional impact are determined, as well as their possible applications. We close this thesis by concluding that there is a voice model that can improve business communication performance, all evidenced through the different instruments that have been used in the present work, mentioned above. We chose, according to these evidences, for a discourse with a rather agile tempo, without too many pauses and that include tonal inflections, with a prosody rich in tonalities, with a rather moderate volume and without influence on the part of the genre, although in the latter case you may have context-related exceptions.

Full textThe main focus of this thesis is to better understand the role of genomic methylation changes in colorectal cancer. We approached it at two different levels: (1) global assessment and (2) analysis of specific recurrent changes. A new technique called Amplification of InterMethylated Sites (AIMS) was developed to obtain information at both levels. At global level we report the relative contribution of losses and gains of DNA methylation on the tumour progression. DNA methylation signatures associate with different tumour features, including physiological, genetic and clinical characteristics. Furthermore, we demonstrate that global genomic demethylation correlates with cumulated genomic damage and poor prognosis. At specific level we show the epigenetic silencing of the prostacyclin synthase gene (PTGIS) in 43% of colorectal cancers. PTGIS inactivation is associated with the aneuploid status of the tumour, suggesting a possible role of this gene in the maintenance of the genomic integrity. Finally, we have detected a new type of epigenetic alteration affecting a large proportion of colorectal cancers. It consists in a long range epigenetic silencing due DNA methylation and Histone modification changes and affects an entire cytogenetic band (2q14.2). All the genes and transcripts present in this region showed downregulation independently of the promoter methylation status suggesting that the regional condition prevails over the local status.

Full textEl cáncer de endometrio es la neoplasia ginecológica más frecuente en los países desarrollados. A pesar de que la mayoría de los carcinomas son curables con un tratamiento adecuado, alrededor del 20% de los tumores se comportan de forma agresiva y suponen un reto terapéutico. Por este motivo surge la necesidad de identificar nuevos parámetros que permitan seleccionar pacientes con riesgo de recidiva o metástasis. La célula eucariota presenta cambios en su metabolismo como respuesta coordinada a diferentes situaciones fisiológicas y patológicas, entre ellas el cáncer. El análisis del metaboloma, mediante la metabolómica, puede ayudar a identificar metabolitos diferenciales que representan el producto final de las vías de señalización que están alteradas en el cáncer. Por esta razón hemos querido realizar un análisis metabolómico del cáncer de endometrio. Además, para la validación de los resultados y su translación a la práctica clínica se han evaluado los niveles de expresión de los metabolitos diferenciales más significativos en arrays de tejido (TMAs). En primer lugar, los resultados han mostrado que el proceso de carcinogénesis del cáncer de endometrio define un perfil metabolómico específico. Los resultados sugieren que la vía de los endocannabinoides puede estar implicada en la génesis y progresión del carcinoma endometrioide. Además, la alteración del metabolismo de las purinas puede estar implicada en fenómenos de invasión miometrial en el cáncer de endometrio. En segundo lugar, el estudio metabolómico ha mostrado un perfil diferencial entre carcinomas endometrioides y serosos. Además ha permitido identificar dos moléculas, ADI1 i BCAT1, que pueden estar implicadas en la génesis de las neoplasias endometrioides así como en la progresión tumoral. Asimismo, estos dos compuestos pueden ser útiles en el diagnóstico diferencial de estos dos subtipos histológicos con pronósticos tan distintos. Finalmente, partiendo de la base que la angiogénesis es un mecanismo esencial para el crecimiento, invasión y diseminación tumoral y que los carcinomas de endometrio con flujo sanguíneo intratumoral disminuido tienen peor pronóstico, se ha analizado el perfil metabolómico del cáncer de endometrio en función de su flujo sanguíneo. Los resultados muestran un perfil metabolómico específico de los tumores según su flujo sanguíneo y permiten identificar Resolvina D i fosfolípidos específicos diferenciales entre tumores de alto y bajo flujo sanguíneo. Estas moléculas pueden estar implicadas en la angiogénesis y progresión tumoral en el cáncer de endometrio.
Endometrial cancer is the most frequent gynecological malignancy in developed countries. Although most carcinomas are curable with adequate treatment, about 20% of tumors behave aggressively and pose a therapeutic challenge. For this reason, there is a need to identify new parameters that allow the selection of a patient with risk of recurrence or metastasis. The eukaryotic cell presents changes in its metabolism as a coordinated response to different physiological and pathological situations, including cancer. The analysis of the metabolome, through metabolomics, can help identify differential metabolites that represent the final product of the signaling pathways that are altered in cancer. For this reason we wanted to perform a metabolomic analysis of endometrial cancer. In addition, for the validation of the results and their translation to clinical practice, the expression levels of the most significant differential metabolites have been evaluated using tissue arrays (TMAs). First, the results have shown that the process of carcinogenesis of endometrial cancer defines a specific metabolomic profile. The results suggest that the endocannabinoid pathway may be involved in the genesis and progression of endometrioid carcinoma. In addition, the alteration of the purine metabolism may be involved in myometrial invasion phenomens in endometrial cancer. Second, the metabolomic study has shown a differential profile between endometrioid and serous carcinomas and has allowed the identification of two molecules, ADI1 and BCAT1, which may be involved in the genesis of endometrioid neoplasms as well as in tumor progression. Likewise, these two compounds can be useful in the differential diagnosis of these two histological subtypes with such different prognoses. Finally, starting from the basis that angiogenesis is an essential mechanism for tumor growth, invasion and dissemination and that endometrial carcinomas with decreased intratumoral blood flow have a worse prognosis, the metabolomic profile of endometrial carcinoma has been analysed according to its blood flow. The results show a specific metabolomic profile of the tumors according to their blood flow and allow identifying Resolvin D and specific phospholipids differentials between high and low blood flow tumors. These molecules may be involved in angiogenesis and tumor progression in endometrial cancer.

Full textObjectius de la Tesi: a) investigar la presència d'alteracions en l'activitat i expressió de PON1 en hepatopaties cròniques humanes i experimentals, i estudiar els mecanismes moleculars relacionats; b) avaluar un nou assaig enzimàtic utilitzant un substrat no tòxic que mesura l'activitat lactonasa de PON1; c) estudiar l'eficàcia diagnòstica de la determinació de l'activitat PON1 en l'avaluació clínica de la malaltia hepàtica.
Conclusions: 1) PON1 podria regular l'estrés oxidatiu mitjançant la degradació de lipoperòxids; la inflamació, actuant com una barrera contra la inflamació induïda per MCP-1; i l'apoptosi cel·lular, correlacionant-se amb un augment en la forma soluble del receptor FAS (sFAS) 2) L'activitat PON1 en sèrum de pacients hepatòpates podria disminuir a causa d'alteracions en la mida i composició de les HDL, i/o d'un augment en l'estrés oxidatiu 3) L'expressió hepàtica i sèrica de PON1 augmentarien a causa d'una disminució en la síntesi d'HDL, i d'una disminució de la proteòlisi cel·lular 4) La determinació de l'activitat lactonasa de PON1 en sèrum, utilitzant el substrat TBBL, és un mètode fiable, no tòxic i semi-automàtic, i està menys influenciada pels polimorfismes genètics que l'activitat esterasa utilitzant paraoxó 5) La determinació de l'actividad PON1 sèrica té una elevada eficàcia diagnòstica i pot ser un útil complement a les proves de valoració de la funció hepàtica que s'utilitzen en la pràctica clínica.
The family of serum paraoxonases (PON) consist of three enzymes: PON1 (the most investigated member), PON2 and PON3. In humans, PON1 expression is mainly found in the liver, and circulates tightly bound to HDL. PON1 is a polymorphic enzyme that is able to degradate organophosphates and different type of esters, lactones and xenobiotics, but its physiological function is to hydrolise lipid peroxides. It has also an antiinflamatoy role since it can attenuate MCP-1 (a proinflamatory chemokine) secretion. Oxidative stress and inflammation play key roles in the development of liver diseases. Since PON1 has a protective effect against oxidative stress, it could be plausible to find an association between PON1 and chronic hepatic diseases.
Aims of the Thesis: a) to investigate the presence of alterations in PON1 activity and expression in human and experimental chronic hepatic diseases, and to study the molecular mechanisms involved; b) to evaluate a new enzymatic assay using a non toxic substrate that measures PON1 lactonase activity; c) to assess the diagnostic accuracy of the measurement of serum PON1 activity in the clinic evaluation of liver diseases.
Conclusions: 1) PON1 could regulate oxidative stress by lipid peroxides degradation; inflammation, by acting as a barrier against MCP-1 induced inflammation; and cell apoptosis, by its relationship with the increase of sFAS, the soluble form of FAS receptor 2) Serum PON1 activity in patients with chronic liver disease could decreased as a consequence of alterations in the size and composition of HDL, and/or an increase of oxidative stress 3) Serum and hepatic PON1 expression would increase because of the decrease in HDL synthesis, and the decrease of cellular proteolysis 4) Serum PON1 lactonase activity measurement, using TBBL as a susbtrate, is a reliable, non-toxic, semi-automated assay, and is less influenced by genetic polymorphisms than PON1 esterase activity using paraoxon 5) Serum PON1 activity measurement has a high diagnostic accuracy and may contribute significantly to the evaluation of liver function in the clinical setting.

Full textL'objectiu general d'aquest treball és estudiar la incidència d'aneuploïdia en la línia germinal femenina i en els primers estadis del desenvolupament embrionari.
S'han utilitzat oòcits descartats de cicles de FIV per a desenvolupar una metodologia de hibridació in situ fluorescent (FISH) que permet detectar nou cromosomes en 1CPs i en MII. Fins ara, les absències de cromosomes o cromàtides en 1CP es consideraven artefactes però la valoració de la complementarietat 1CP- MII realitzada constata que només ho són una minoria (25,8%).
Tant la freqüència d'aneuploïdia obtinguda per als nou cromosomes estudiats (47,5%) com el risc estimat d'aneuploïdia per els 23 cromosomes (57,2%) són molt elevats. El risc estimat de segregació anòmala per cromosoma analitzat és del 0,89%.
S'han identificat diferents mecanismes de generació d'aneuploïdies en l'oòcit: separació precoç de cromàtides germanes (observada amb més freqüència al 1CP que a la MII) i no-disjunció de cromosomes homòlegs en la meiosi i segregació anòmala en la mitosi de l'etapa proliferativa de la línia germinal (mosaïcisme gonadal). Aquest fenomen s'ha detectat en un 25,7% de les pacients analitzades i fa recomanable el diagnòstic prenatal a les pacients que quedin gestants després d'un DGP-1CP.
Aplicant DGP-1CP a dones amb cariotip normal (dones d'edat avançada), la incidència d'aneuploïdia per als nou cromosomes ha estat del 60,4%, corroborant a aquest grup com a grup de risc per la presència d'aneuploïdies. Aplicant-lo a dues pacients portadores de translocacions robertsonianes s'ha trobat una taxa d'aneuploïdia molt alta per als cromosomes no implicats en la translocació (91,7% i 72,7%), independentment de les alteracions observades per als cromosomes de la translocació.
L'anàlisi d'aneuploïdies en blastòmers de pacients portadors i portadores de translocacions recíproques mostra un alt índex d'aneuploïdies de cromosomes no implicats en la translocació (60,3%) i també un alt percentatge de mosaïcisme (58,7%), tenint en compte tant els cromosomes implicats com els no implicats en la translocació. S'han trobat embrions normals o equilibrats per la translocació però aneuploides per altres cromosomes.
Sembla necessari l'estudi seqüencial de la segregació dels cromosomes implicats en la translocació i de les aneuploïdies per altres cromosomes, en pacients portadors de translocacions.
Per a validar la interpretació del resultat de la FISH en l'anàlisi d'aneuploïdia en cèl·lules proliferants, s'han estudiat cèl·lules en estadi de G0 (cèl·lules de Sertoli) i cèl·lules proliferants (limfòcits). En aplicar FISH en cèl·lules en proliferació s'estima que el 10,8% de dobles marques en excés trobades, en comparació amb les trobades en cèl·lules no proliferants, no són senyals partits, sinó deguts al procés de replicació. L'aplicació de FISH en cèl·lules en proliferació, com són els blastòmers, pot dificultar la interpretació dels resultats de FISH. Caldria incloure marcadors de l'inici o el final de la replicació per tal de ser usats simultàniament amb les sondes diagnòstiques de FISH en realitzar un DGP en blastòmers.
El DGP per a la detecció d'aneuploïdies és un procediment més del que es disposa per tal d'oferir als pacients amb risc tot i que s'ha de valorar, en cada cas, si la seva aplicació pot ser beneficiosa.
Cytogenetic analysis of the 1st polar body (1PB) allows an indirect characterisation of the oocyte in the metaphase II stage (MII) without compromising its reproductive capability. This allows, in an in vitro fertilisation treatment (IVF), the development of a variant of preimplantation genetic diagnosis in which the 1PB is analysed (PGD-1PB).
The aim of this study is to analyse the aneuploidy rate in the female germ-cell line and in its first embryo development stages.
We have used oocytes discarded from IVF cycles to develop a fluorescent in situ hybridisation (FISH) method that allows for the detection of nine chromosomes in 1PBs and in MII. Until now, missing chromosomes or chromatids in the 1PB have been considered as artefacts but the evaluation of the 1PB-MII complement could proves that they are only a minority (25.8%).
Both the aneuploidy rate found for the nine chromosomes analysed (47.5%) and the estimated risk of aneuploidy for the 23 chromosomes (57.2%) are very high. The abnormal segregation percentage per analysed chromosome is 0.89%.
Different mechanisms for the generation of aneuploidies have been identified: predivision of sister chromatids (more frequently observed in 1PB than in MII) and non-disjunction of homologous chromosomes in meiosis I and altered segregation in mitosis during the proliferative stage in the germ-cell line (gonadal mosaicism). This phenomenon has been found in 25.7% of the analysed patients and makes the application of prenatal diagnosis in patients which become pregnant after a PGD-1PB advisable.
When applying PGD-1PB in females with a normal karyotype (advanced maternal age), the aneuploidy rate for the nine chromosomes is 60.4%, corroborating this group as a risk group for the presence of aneuploidies. Applying it to two female carriers of Robertsonian translocations, a high aneuploidy rate for the chromosomes not implicated in the translocation has been found (91.7% and 72.7%), independently of the alterations observed in the chromosomes of the translocation.
The analysis of aneuploidies in blastomeres of male and female reciprocal translocation carriers shows a high aneuploidy rate for the chromosomes not involved in translocations (60.3%) and also a high percentage of mosaicism (58.7%), including both the chromosomes implicated and not implicated in the translocation. Normal and balanced embryos for the translocation, but with aneuploidies for other chromosomes, have been found.
In translocation carriers, the sequential analysis of the segregation of the chromosomes involved in the translocation and the aneuploidy screening for other chromosomes seems necessary,
In order to validate the interpretation of FISH results in the aneuploidy screening of proliferating cells, G0 stage cells (Sertoli cells) and proliferating cells (lymphocytes) have been studied. When applying FISH in proliferating cells, 10.8% extra double-dots found, in comparison with the ones found in non-proliferating cells, are not splits but are due to the replicating process.
The use of FISH in proliferating cells as blastomeres could make the interpretation of FISH results difficult. It would be necessary to include markers of the beginning or the end of replication to be simultaneously used with other FISH probes in PGD-analysed blastomeres.
PGD for aneuploidy screening is another procedure which is available to be offered to patients at risk although it has to be evaluated, case by case, to determine if its application can be beneficial.

Full textHYPOTHESIS: Neurosensorial impairment related to Turner’s syndrome (TS) are due to chromosomic disorders characteristic of these patients and the degree of impariment is related with the degree of the karyotypic disorder. The consequences of hypoestrogenism are reversible with substitutive hormonal therapy. AIM: To define the origin of the hearing loss observed in TS women in adulthood; to assess whether there are olfactory and gustatory impairments related to this syndrome; and to demonstrate that patients with other congenital hypogonadism without karyotypic disorder do not show such comorbities. METHODS: Three cohort of women were studied; TS women; women with other congenital hypogonadisms, healthy women taking hormonal contraception, since hypogonadism were under substitutive hormonal therapy. Quality of life data was recorded using two questionnaires (SF-36 and FSFI). Clinical data was also gathered for each patient. Hearing impairment was assessed though a microotoscopy, standard audiometry and auditory evoked potentials. Using the BAST-24 test the test and smell sensitivity and sensibility was evaluated. RESULTS: Hearing impairment was observed among TS women, being the neurisensorial pattern the most frequent among them. The cause of this kind of impairment is diverse, being possible the age, genotype or even history of recurrent otitis during childhood. Impairment in smell was also observed in TS patients. Although sensitivity was not found impaired, it was observed that sexual hormones have a role in intensity and irritability of odours. It was not found any alteration in taste sense in any congenital hypogonadism. When it comes to quality of life, all patients with congenital hypogonadism show lower score in the physical domain than healthy controls. Only half of the TS patients mentioned to mantain sexual relationships. Sexual activity was not related to TS comorbidities but sexual active TS were taller than sexually inactive. Women with other congenital hypogonadism show low scores in sexual function, despite hormonal therapy. It was atempted to use urotelial cells to perform karyotype analysis, but its culture is tough and correlation with phenotype is worse than blood karyotyping. Therefore its use is discouraged.
