    The physical parameters of sound amplitude, frequency and phase are received by the human senses as loudness, pitch, timbre and duration. The interest focuses on determining the threshold between the use of sound as a communication tool and enjoy and its conversion into an element of aggression. Noise pollutant pressure acoustic waves impact in the ear when its intensity exceeds its defensive mechanisms and cause hearing loss (typically affecting the 4,000 Hz). But still there are some extra-auditory pathways to the hippocampus and reticuloendothelial system, responsible for the other noise effects such as physical-somatic (cardiovascular, hormonal, respiratory, sleep, gastrointestinal), emotional, psychological (discomfort, alterations in the learning and performance) and psychiatric problems. The component of the low-frequency vibration noise causes discomfort and disorders too.Los parámetros físicos del sonido: amplitud, frecuencia y fase, se reciben en el ser humano como variables sensoriales de sonoridad, altura, timbre y duración subjetiva. El interés se centra en determinar el umbral entre la utilización de los sonidos como herramienta de comunicación y disfrute y su conversión en elemento de agresión. Las ondas de presión sonora del contaminante acústico impactan en el oído cuando su intensidad supera sus mecanismos defensivos y causa hipoacusia (típicamente afectando los 4.000 Hz). Pero también siguen unas vías extraauditivas dirigidas al hipocampo y sistema reticuloendotelial, responsables de los demás efectos del ruido físicos-somáticos (cardiovasculares, hormonales, respiratorios, sobre el sueño, gastrointestinales), emocionales, psicológicos (malestar, alteraciones en el aprendizaje y el rendimiento) y psiquiátricos. El componente vibratorio de las bajas frecuencias sonoras también es causa de malestar y enfermedades

    Se describe un caso de carcinoma tiroideo en una gata mestiza de 6 años de edad, siendo este tipo de tumores tiroideos de baja incidenica en la clínica felina. ELanimal presentaba un historialde disfagia de aproximadamente 3 semanas de evolución debido a la presencia de una masa dura en la porción ventral del cuello. El estudio radiológico de la región cervical puso de manifiesto la existencia de una masa de densidad tejido blando, y en el examen ecográfico se pudo apreciar una estructura hipoecogénica con áreas centrales anecógenas y focos de mineralización. El examen citológico de una muestra de la masa obtenida mediante aspiración con aguja fina era compatible con una inflamación o con un tumor tipo epitelial. El tratamiento consistió en la exéresis de la masa. La evolución tra la intervención fue favorable, pero aproximadamente un año después el animal había adelgazado, estaba anoréxico y con una ligera dificultad respiratoria. Se realizaron radiografía torácicas y en ellas se pudo observar la presencia de múltiples nódulos, lo cual era compatible con una metástasis pulmonar.

    AbstractObjectiveThe histological classification of the World Health Organization (WHO), along with improved imaging studies, provide relevant information for the management of parotid carcinomas. However, the prognosis depends on factors other than histology and tumor extension. This article evaluates the usefulness of a prognostic classification of parotid cancers, including these factors in patients in a hospital area.MethodsA follow-up was conducted on 19 patients with parotid carcinomas, excluding lymphoid tumors or intra-parotid metastases, between 1998 and 2012. The prognostic index was obtained from the formulas proposed by Vander Poorten, with factors including age, tumor size, lymph node involvement, skin invasion, facial nerve involvement, perineural growth and margins of resection, before surgery (PS1) and after (PS2). Overall survival was related to 5 years for each patient based on their inclusion in any of the 4 risk groups defined.ResultsRisk stratification based on the results Vander Poorten PS2 was distributed into Risk Groups (GR) 1 (3 patients, 15.7%), 2 (5 patients, 26.3%), 3 (1 patient, 5.8%) and 4 (10 patients, 52.2%). The 6 patients who died during follow-up belonged to GR4. Only one of the 4 patients belonging to GR4 has exceeded the 5-year survival up to the current time.The comparison of the values that relate the pretreatment (PS1) and after treatment (PS2) results showed overall survival in patients with PS1<4.5 and PS2<4.9, whereas mortality was greater with indices of PS1>6.5 and PS2>7.7.ConclusionsVander Poorten index can be applied in hospital areas with small numbers of parotid carcinomas. It enables a more accurate prognosis for individual patients

    Local Tramadol Improves the Anesthetic Success in Patients with Symptomatic Irreversible Pulpitis: A Meta-Analysis

    Symptomatic irreversible pulpitis is a painful clinical condition with a broad inflammatory component. Dental anesthesia in these patients is affected by the inflammatory process, reporting a high incidence of anesthesia failure. The aim of this systematic review and meta-analytical evaluation was to determine the effect of pre-treatment with tramadol in patients with symptomatic irreversible pulpitis, as well as for pain control and adverse effects. This study was registered in PROSPERO (ID: CRD42021279262). PubMed was consulted to identify clinical investigations comparing tramadol and placebo/local anesthetics in patients with symptomatic irreversible pulpitis. Data about the anesthesia, pain control, and adverse effects were extracted. Both the anesthetic success index and the adverse effects of local tramadol and placebo were compared with the Mantel–Haenszel test and odds ratio. Data analysis showed that the local administration of tramadol increased the anesthetic success rate when compared to placebo in patients with symptomatic irreversible pulpitis (n = 228; I2 = 0; OR = 2.2; 95% CIs: 1.30 to 3.79; p < 0.004). However, local administration of tramadol increased the risk of adverse effects when compared to placebo/local anesthetics (n = 288; I2 = 0; OR = 7.72; 95% CIs: 1.37 to 43.46; p < 0.02). In conclusion, this study shows that the local administration of tramadol increases the anesthetic success index when compared to placebo in patients with symptomatic irreversible pulpitis

    Transverse Cervicothoracic Stabbing: Multidisciplinary Management of a Surgical Emergency

    Get PDF
    Tracheobronchial injuries are closely related to orotracheal intubations and chest traumas. Stabbing injuries are very rare and often life threatening because of the damage to vital structures such as the respiratory tract and large arterial or venous vessels. Early diagnosis and treatment of penetrating neck injuries increase survival rates. We report a case of the tracheobronchial section with a penetrating stabbing wound on the left laterocervical area associated with contralateral pneumothorax, requiring urgent surgical pulmonary repair, tracheal suture, and tracheotomy. Prompt action with a multidisciplinary approach resulted in a favorable outcome

    Loss of smell and taste can accurately predict COVID-19 infection: a machine-learning approach

    The COVID-19 outbreak has spread extensively around the world. Loss of smell and taste have emerged as main predictors for COVID-19. The objective of our study is to develop a comprehensive machine learning (ML) modelling framework to assess the predictive value of smell and taste disorders, along with other symptoms, in COVID-19 infection. A multicenter case-control study was performed, in which suspected cases for COVID-19, who were tested by real-time reversetranscription polymerase chain reaction (RT-PCR), informed about the presence and severity of their symptoms using visual analog scales (VAS). ML algorithms were applied to the collected data to predict a COVID-19 diagnosis using a 50-fold cross-validation scheme by randomly splitting the patients in training (75%) and testing datasets (25%). A total of 777 patients were included. Loss of smell and taste were found to be the symptoms with higher odds ratios of 6.21 and 2.42 for COVID-19 positivity. The ML algorithms applied reached an average accuracy of 80%, a sensitivity of 82%, and a specificity of 78% when using VAS to predict a COVID-19 diagnosis. This study concludes that smell and taste disorders are accurate predictors, with ML algorithms constituting helpful tools for COVID-19 diagnostic prediction.Junta de Andalucí

    En este trabajo presentamos los resultados previos de la intervención arqueológica de salvamento realizada en la Cueva de las Palomas de Teba con motivo de las inundaciones acaecidas en octubre de 2018. La erosión provocada por las lluvias torrenciales en el yacimiento hizo que abundante material arqueológico quedara expuesto a acciones de destrucción y expolio, lo que motivó que se llevara a cabo una intervención arqueológica de urgencia para evitar una pérdida patrimonial de mayor consideración.The previous results of the archaeological rescue intervention carried out in Las Palomas Cave of Teba due to the floods that occurred in October 2018 is presented in this paper. Erosion caused by to - rrential rains in the site caused abundant archaeological material to be exposed to actions of destruction and pillage, which led to an emergency archaeological intervention to avoid a loss of heritage of greater consideratio

    At the beginnings of the funerary Megalithism in Iberia at Campo de Hockey necropolis

    Get PDF
    [EN] The excavations undertaken at the Campo de Hockey site in 2008 led to the identification of a major Neolithic necropolis in the former Island of San Fernando (Bay of Cadiz). This work presents the results of the latest studies, which indicate that the site stands as one of the oldest megalithic necropolises in the Iberian Peninsula. The main aim of this work is to present with precision the chronology of this necropolis through a Bayesian statistical model that confirms that the necropolis was in use from c. 4300 to 3800 cal BC. The presence of prestige grave goods in the earliest and most monumental graves suggest that the Megalithism phenomenon emerged in relation to maritime routes linked to the distribution of exotic products. We also aim to examine funerary practices in these early megalithic communities, and especially their way of life and the social reproduction system. As such, in addition to the chronological information and the Bayesian statistics, we provide the results of a comprehensive interdisciplinary study, including anthropological, archaeometric and genetic data.We wish to express our gratitude to Antonio Saez Espligares (Historical Museum of San Fernando) and Lourdes Lorenzo (Figlina, s.l.) for their support during the archaeological excavation.
