RESUMEN
INTRODUCTION: Non-fluent aphasia is a frequent complication in post-ischemic stroke patients, with repetitive transcranial magnetic stimulation (rTMS) being one of the possible treatment alternatives. AIM: To assess the efficacy and safety of rTMS in patients with non-fluent after-ischemic stroke aphasia. PATIENTS AND METHODS: Double blind, randomized controlled clinical trial in post-stroke patients who were assigned to receive 10 sessions (one daily) of active treatment or placebo of rTMS, without the addition of language therapy. The baseline characteristics were compared initially and the efficacy between the active group versus the placebo group at day 30 was evaluated through a Mann-Whitney U test. RESULTS: 82 patients were included: active group (n = 41) and placebo group (n = 41). At baseline, statistically significant differences were found between the groups in favor of the placebo in the domains of the Boston test of auditory compression (p = 0.024), denomination (p = 0.014) and praxis (p = 0.026), and also occurred on the 30th day in the naming domains (p = 0.037) and reading (p = 0.001). There were 39 adverse reactions: 23 (26.83%) in the active group vs 16 (21.96%) in the placebo group (p = 0.290); the majority corresponded to episodes of mild headache. CONCLUSION: rTMS is a safe therapy, however, given the conditions of this study, we could not demonstrate the efficacy of rTMS versus placebo in patients with non-fluent aphasia with involvement of Broca's area after an ischemic stroke.
TITLE: Eficacia y seguridad de la estimulacion magnetica transcraneal en pacientes con afasia no fluente, posterior a ictus isquemico. Ensayo clinico controlado, aleatorizado y doble ciego.Introduccion. La afasia no fluente es una complicacion frecuente en pacientes postictus isquemico y la estimulacion magnetica transcraneal repetitiva (EMTr) representa una de las posibles alternativas de tratamiento. Objetivo. Evaluar la eficacia y la seguridad de la EMTr en pacientes con afasia no fluente postictus isquemico. Pacientes y metodos. Ensayo clinico controlado doble ciego, aleatorizado, en pacientes postictus isquemico que fueron asignados a recibir 10 sesiones (una diaria) de tratamiento activo o placebo de EMTr, sin adicion de terapia del lenguaje. Las caracteristicas basales fueron comparadas inicialmente, y la eficacia entre el grupo activo frente al grupo placebo el dia 30 se evaluo a traves de una prueba U de Mann-Whitney. Resultados. Se incluyo a 82 pacientes: grupo activo (n = 41) y grupo placebo (n = 41). Se encontraron diferencias basales estadisticamente significativas entre los grupos a favor del placebo en los dominios del test de Boston de compresion auditiva (p = 0,024), denominacion (p = 0,014) y praxis (p = 0,026), e igualmente ocurrio el dia 30 en los dominios de denominacion (p = 0,037) y lectura (p = 0,001). Se presentaron 39 reacciones adversas, 23 en el grupo activo (26,83%) frente a 16 (21,96%) en el grupo placebo (p = 0,290), y la mayoria correspondia a episodios de cefalea leve. Conclusion. La EMTr es una terapia segura, pero dadas las condiciones de este estudio, no pudo demostrarse la eficacia de la EMTr frente al placebo en pacientes con afasia no fluente con afectacion del area de Broca posterior a un ictus isquemico.

PURPOSE: The analysis of epidermal growth factor receptor (EGFR) mutations in many patients with advanced non-small-cell lung cancer (aNSCLC) has provided the opportunity for successful treatment with specific, targeted EGFR tyrosine kinase inhibitors. However, this therapeutic decision may be challenging when insufficient tumor tissue is available for EGFR mutation testing. Therefore, blood surrogate samples for EGFR mutation analysis have been suggested. METHODS: Data were collected from the Spanish cohort of patients in the large, non-interventional, diagnostic ASSESS study (NCT01785888) evaluating the utility of circulating free tumor-derived DNA from plasma for EGFR mutation testing. The incidence of EGFR mutation in Spain and the level of concordance between matched tissue/cytology and plasma samples were evaluated. RESULTS: In a cohort of 154 eligible patients, EGFR mutations were identified in 15.1 and 11.0% of tumor and plasma samples, respectively. The most commonly used EGFR mutation testing method for the tumor tissue samples was the QIAGEN Therascreen® EGFR RGQ PCR kit (52.1%). Fragment Length Analysis + PNA LNA Clamp was used for the plasma samples. The concordance rate for EGFR mutation status between the tissue/cytology and plasma samples was 88.8%; the sensitivity was 45.5%, and the specificity was 96.7%. CONCLUSIONS: The high concordance between the different DNA sources for EGFR mutation testing supports the use of plasma samples when tumor tissue is unavailable.

INTRODUCTION: Findings from several epidemiological studies have revealed that major depression is associated with an increased risk of developing cardiovascular diseases (CVD) and presenting complications and new events in subjects with already-established CVD. The pathophysiological mechanisms responsible for this increased cardiovascular risk in major depression remain unclear. DEVELOPMENT: The aim of this work is to review the literature on the possible pathophysiological mechanisms involved in the relation between major depression and CVD, with special emphasis on the studies dealing with cardiovascular autonomic dysfunction and heart rate variability. Likewise, recent hypotheses concerning the neural mechanisms underlying autonomic dysfunction in subjects with major depression are also discussed. CONCLUSIONS: The evidence that is currently available allows us to hypothesise that there are anomalies in the functioning of the central autonomic neural network in subjects with major depression, and more specifically in the hippocampus, prefrontal cortex and the brain stem nuclei. Such abnormalities, in association with lower central levels of serotonin give rise to a predominance of the sympathetic flow and a loss of cardiac vagal tone. The resulting cardiovascular autonomic dysfunction could be the main cause of the increased cardiovascular risk observed in major depression. In the future, studying the autonomic nervous system may be a useful tool in the development of new therapeutic strategies aimed at reducing cardiovascular morbidity and mortality in subjects with depression.

Early detection and treatment of preinvasive neoplasias decrease the incidence and mortality of the subsequent invasive cancers. This paper presents the results of a selective program to detect vulvar intraepithelial neoplasia (VIN). The program was selective because only "relative high risk" women were included, i.e. women with one or more of the following items: a) age more than 50 years; b) past history of epidermoid cervical or vaginal cancer (included intraepithelial stages); c) past history of genital radiation; d) past or actual history of genital condyloma; and e) past or actual history of hyperplasic or mixed vulvar dystrophy. Detection was made with the test described by Collins et al., staining the vulva with a toluidine blue aqueous solution and decoloring it with acetic acid. All positive sites (areas retaining the blue color) were biopsied under local anesthesia. Histopathology diagnosis served as gold standard for the program's evaluation. Patient with negative tests and those with NIV I were rescreened each 6 months. From March 1984 to September 1986, 212 patients were admitted in this program and 318 tests were performed. Individual tests varied from 1 (105 patients) to 5 (3 patients). The group was followed-up until March 1989, when the program was evaluated. There were 77 positive tests, among them 21 cases of NIV. Three women with NIV I progressed to NIV II during the observation period. NIV cases were classified as: NIV I, 7 cases (33.3%); NIV II, 10 cases (47.7%); and NIV III, 4 cases (19.0%).(ABSTRACT TRUNCATED AT 250 WORDS)

From 1978 to 1985 we have found 14 cases of vaginal intraepithelial neoplasia (VAIN) in patients previously hysterectomized. VAIN was detected by an abnormal cytology; diagnostic process included a second cytology, colposcopy, Schiller test, and directed biopsies. VAIN was classified as grade I in 5 patients (35.7%); grade II in 5 patients (35.7%); and grade III in 4 patients (28.6%). Pathogenic classification of VAIN was: VAIN de novo 9 cases (64.3%); VAIN after vaginal irradiation, 3 cases (21.4%); VAIN following incomplete removal of a cervical intraepithelial neoplasia, one case (7.1%); and VAIN as manifestation of a multicentric neoplasia of the lower genital tract, one case (7.1%). The mean time between hysterectomy and VAIN diagnosis was 6.9 years; this time was larger for those women hysterectomized by benign uterine diseases (9.0 years vs. 2.4 years). Our conclusion is that patients who have lost their uterus by malignant or benign diseases should be followed-up with periodic vaginal cytology in order to detect vaginal neoplasia in its pre-invasive stages.

Con el proposito de establecer el valor de la determinacion de la gonadotropina corionica (HCG) como marcador tumoral, se estudiaron 100 pacientes con diagnostico de neoplasia maligna no trofoblastica, incluyendose 40 controles sanos; a todos se les realizo cuantificacion en suero de HCG por medio de la subunidad beta, por radioinmunoalisis (RIA) empleando la tecnica de doble anticuerpo. El 10 por ciento de los casos, presento niveles detectables de dicha hormona; el tipo de neoplasia y la frecuencia de positividad encontrados fueron los siguientes: dermatofibrosarcoma: 100 por ciento, seminoma y teratoma testicular 66.6 por ciento, hepatoma 25 por ciento, carcinoma renal 25 por ciento, carcinoma cervicouterino 14.8 por ciento, carcinoma de mama 14.2 por ciento; en el resto de pacientes como en los casos control, las determinaciones para beta HCG fueron negativas. Se concluye, que aunque la produccion de beta HCG por diversas neoplasias malignas no trofoblasticas, puede variar del 0 al 100 por ciento, la positividad para esta fraccion hormonal en ausencia de embarazo, es sugestiva de algun proceso tumoral

A 42 year old man without history of rheumatic heart disease was admitted to the hospital with severe aortic insufficiency and heart failure. There were no clinical data of an infectious disease. The bidimensional echocardiogram showed vegetations involving the aortic valve leaflets. With the diagnosis of acute aortic insufficiency caused by infective endocarditis the patient was submitted to surgery. During surgery the existence of endocarditis secondary to a mycotic agent was demonstrated. The fungus was latter identified as aspergillus fumigatus. The postoperative course was uneventful. The good results obtained in this case confirm recent reports advising an urgent surgical approach of cases of infective endocarditis secondary to mycotic agents, and support the view that echocardiography may be a valuable tool in the diagnosis of this entity.

Se informa el caso de un paciente del sexo masculino de 42 anos de edad, quien sufrio endocarditis de la valvula aortica producida por aspergillus fumigatus. La forma de presentacion fue una insuficiencia aortica severa e insuficiencia cardiaca. El cuadro clinico no mostro las manifestaciones habituales de endocarditis y el diagnostico se sospecho ante la presencia de insuficiencia aortica aguda, confirmandose despues con ecocardiografia y cultivo del tejido valvular extirpado.Se manejo quirurgicamente en forma temprana con resultados satisfactorios. Un ano despues de la cirugia se mantenia asintomatico y en clase funcional I. Los resultados obtenidos en este enfermo, apoyan lo expresado en la literatura en cuanto a que la endocarditis por hongos debe manejarse quirurgicamente en forma temprana, especialmente ante el descubrimiento ecocardiografico de vegetaciones de gran tamano
