    Full Text Available La FA constituye una de las arritmias sostenidas más frecuentes que motivan la consulta. El sustrato comprende diferentes mecanismos, entre los que se encuentra el agrandamiento auricular izquierdo. Presentamos el caso de una mujer de 33 años con antecedentes depalpitaciones, que ingresó en la guardia por FA de alta respuesta ventricular. En la radiografía de tórax se observó una deformación del borde izquierdo de la silueta cardíaca. Posteriormente,el ecocardiograma transesofágico y la resonancia magnética nuclear evidenciaron una megaorejuela aneurismática debida, probablemente, a un defecto pericárdico. La conducta fue anticoagulación oral y tratamiento con atenolol, con evolución favorable.

    Full Text Available La vena cava superior izquierda persistente es la anomalía más común del drenaje venoso del tórax y con frecuencia acompaña a otras anomalías congénitas. Generalmente, su hallazgo es incidental durante la inserción de catéteres venosos centrales. Su diagnóstico puede hacerse por medio de múltiples técnicas de imagen. El principal hallazgo ecocardiográfico es un seno coronario dilatado que sugiere la presencia de vena cava superior izquierda persistente. Cuando ésta drena en la aurícula izquierda, urge la corrección del defecto. Aunque habitualmente tiene un curso benigno, siempre que se documente vena cava superior izquierda conviene buscar otras anomalías congénitas.

    It has been suggested that there is a close association of abnormality in auricular muscles with various congenital auricular deformities. However, there has been no investigation to determine what muscles are involved and how they affect the deformity. The authors examined abnormalities of auricular muscles for patients with various auricular deformities. The authors examined 77 auricles of 62 patients with congenital auricular deformities, including cryptotia, Stahl's ear, prominent ear, lop ear, and others. The superior and posterior auricular muscles from the extrinsic auricular muscle group and the auricular oblique and transverse muscles from the auricular intrinsic muscle group were investigated. The authors found characteristic features of the abnormality of the muscle for each auricular deformity. In nearly all cases of cryptotia, abnormality was found in the superior auricular, auricular oblique, and auricular transverse muscles. Abnormal insertion was found mainly in the superior auricular muscle and was the main cause of cryptotia. In Stahl's ear, the major abnormality was abnormal insertion of the auricular transverse muscle, which creates an abnormal cartilaginous prominence in the scapha. The abnormality in cases of prominent ear was clearly limited mostly to the auricular transverse muscle and, in some cases, to the posterior auricular muscle. In lop ear, abnormality was mostly found in the auricular transverse muscle, with elongation, and in the superior auricular or auricular oblique muscle in some cases. There is a tendency for a specific muscle abnormality to be found in each deformity. It is important to identify the abnormal muscle and correct the abnormality during the operation.

  6. De Populismos, Rupturismo e Izquierdas

    Constantino Urcuyo Fournier

    2008-01-01

    Full Text Available Este artículo pretende avanzar algunas explicaciones generales en torno al llamado giro a la izquierda de los sistemas políticos latinoamericanos. La argumentación trata de mostrar que más que de una sola izquierda se trata de varias izquierdas, tanto por sus definiciones ideológicas como por los diferentes orígenes sociopolíticos de estas fuerzas. Desde el punto de vista ideológico se identifican izquierdas rupturistas, que buscan el cambio del régimen capitalista, e izquierdas pragmáticas que buscan el mejoramiento social en el cuadro sistémico. En cuanto a la izquierda rupturista se analizan sus posiciones frente a: las alianzas sociales, la teoría del partido, el papel de los movimientos sociales y las vías del cambio, la combinación de estrategias de movilización electoral y movilización social. El análisis de las grandes líneas de la economía política de estos movimientos es otro de los aspectos que ocupa la atención de este trabajo; particular atención se presta al resurgir del estatismo y el nacionalismo económicos, como elementos de diferenciación entre estos movimientos. El legado del pasado ideológico y práctico, así como de los sistemas de partidos que anteceden el momento actual, es también motivo de atención. Finalmente, se adopta la tesis de que la llamada "nueva" izquierda tiene fuertes elementos de continuidad, por lo que resulta más adecuado hablar de una reconstrucción sobre los fundamentos del pasado que de la aparición de un fenómeno enteramente nuevo.

  7. Auricular Acupuncture with Laser

    2013-01-01

    Auricular acupuncture is a method which has been successfully used in various fields of medicine especially in the treatment of pain relief. The introduction of lasers especially low-level lasers into medicine brought besides the already existing stimulation with needles and electricity an additional technique to auricular acupuncture. This literature research looks at the historical background, the development and the anatomical and neurological aspects of auricular acupuncture in general and auricular laser acupuncture in detail. Preliminary scientific findings on auricular acupuncture with laser have been described in detail and discussed critically in this review article. The results of the studies have shown evidence of the effect of auricular laser acupuncture. However, a comparison of these studies was impossible due to their different study designs. The most important technical as well as study parameters were described in detail in order to give more sufficient evidence and to improve the quality of future studies. PMID:23935695

    2012-11-01

    Full Text Available La hipertrofia ventricular izquierda es una respuesta maladaptativa a la sobrecarga de presión crónica y un factor de riesgo importante para la fibrilación auricular, insuficiencia cardíaca diastólica, insuficiencia cardíaca sistólica, y la muerte súbita en pacientes con hipertensión. Dado que no todos los pacientes con hipertensión desarrollan hipertrofia ventricular izquierda, hay hallazgos clínicos que se deben tener en cuenta que puede alertar al médico sobre la presencia de hipertrofia ventricular izquierda por lo que una evaluación más definitiva se puede realizar utilizando un electrocardiograma, ecocardiograma o la resonancia magnética cardiovascular. Control de la presión arterial, la restricción de sodio, y la pérdida de peso de forma independiente facilitar la regresión de la hipertrofia ventricular izquierda. Elección de un fármaco antihipertensivo puede ser importante cuando se trata a un paciente con hipertrofia ventricular izquierda hipertensiva. Los inhibidores de la enzima convertidora o bloqueadores del receptor de angiotensina II, seguido por los antagonistas de los canales de calcio, facilitan más rápidamente la regresión de la hipertrofia ventricular izquierda. Con la regresión de la hipertrofia ventricular izquierda, la función diastólica y la reserva de flujo coronario generalmente mejoran, y disminuye el riesgo cardiovascular.

    2005-09-01

    Full Text Available Se presenta el caso de una mujer de 81 años de edad con antecedentes de valvulopatía mitral reumática y fibrilación auricular diagnosticada 10 años antes, que ingresó por un accidente isquémico transitorio carotídeo derecho y un episodio coronario agudo sin elevación del segmento ST en territorio de la arteria coronaria descendente anterior (troponina T elevada y ondas T negativas anterolaterales. En los últimos años había mantenido un adecuado nivel de anticoagulación (INR entre 2,5 y 3,5 con acenocumarol, a excepción del último mes en el que presentó un INR de 1,8. El ecocardiograma transtorácico evidenció una hipocinesia anteroapical y una masa de 2x4 cm, hiperecoica y de contornos redondeados sugestiva de trombo que flotaba libremente en una aurícula izquierda muy dilatada (A, B y C y que, ocasionalmente, protruía en el ventrículo izquierdo (D ocluyendo la válvula mitral que presentaba una estenosis reumática importante (área de 1,0 cm². Debido al alto riesgo de muerte súbita por oclusión del orificio mitral y de embolismos sistémicos, como los que probablemente presentó esta paciente, está indicada la cirugía cardiaca urgente para realizar trombectomía y recambio valvular mitral. La paciente rechazó esta indicación y cinco días más tarde falleció de muerte súbita. Este caso clínico enfatiza la importancia de mantener un adecuado rango de anticoagulación (INR entre 2,5 y 3,5 en pacientes con estenosis mitral reumática y fibrilación auricular crónica debido al alto riesgo de tromboembolismo, así como la indicación de cirugía urgente ante el hallazgo de un trombo que flote libremente en la aurícula izquierda.

    2015-12-01

    Full Text Available We report auricular hematoma cases caused by mobile phones. A 32-year-old male and a 23-year-old female presented with auricular hematoma, having no significant histories of trauma. The patients underwent simple hematoma aspiration. Hematoma re-accumulated in the first case. Incision and drainage were performed, and then auricular skin was stabilized by suturing a gauze pad over the area. Both patients recovered without sequelae after treatment. Judging from these cases, we want to postulate that prolonged mobile phone use may cause auricular hematoma.

    During the period February 1989-September 1991, 15 patients with absent or defective pinna were treated with a bone-anchored auricular prosthesis at the ENT-department, Rigshospitalet, Copenhagen. These patients were followed up from the hospital records and by means of a questionnaire. Altogether 40 titanium implants have been inserted, of which one implant was found not to be integrated at the time of the second-stage surgery. Five patients underwent additional surgery, one patient because of non-integration of a screw, and four patients on account of soft-tissue reactions. From the questionnaire replies it appears that all patients found the cosmetic result and the technique concerning mounting of the prosthesis very satisfactory. Nearly half the patients found that the care of the skin around the abutments caused considerable problems. Three patients had experienced unintended losses of the prosthesis. In conclusion, treatment with a bone anchored auricular prosthesis has considerable advantages compared to treatment with a prosthesis attached by adhesive. Furthermore the use of a bone-anchored prosthesis should be considered a viable alternative to surgical reconstruction because of the outstanding aesthetic result and because the surgical procedure puts less strain on the patient. The disadvantage of the method is the lifelong daily care of the skin and the dependence on the health services.

    Full Text Available Differences in the balance of shape, size, and position of body organs are immediately perceived as "looking wrong" and this perception can subject the individual to significant peer ridicule and social ostracism, often expressing as intense shame and anguish in the attitude of the afflicted. Rehabilitation of such patients can be remarkably beneficial on the individual′s self-esteem and body image. The onus of the deed lies in the hands of a team that combines artistic excellence with surgical expertise, by combining the skills of anaplastologists, surgeons, and prosthodontists. This is a review of a few surgical and prosthetic considerations in the management of auricular defect and a case description of management of a patient of microtia following similar guidelines in fabrication of the epithesis.

  18. La izquierda colombiana, un caso particular en el escenario latinoamericano

    2015-04-01

    Full Text Available En los últimos 25 años en el panorama político de Latinoamérica se pueden apreciar dos fenómenos evidentes. Primero, la crisis del modelo neoliberal instaurado en el continente a partir del Consenso de Washington y, segundo, la respuesta popular que condujo al ascenso de movimientos pertenecientes a un amplio espectro de la izquierda. Colombia, a pesar de mantener una activa movilización social, no ha logrado sumarse a esta tendencia regional. La intervención permanente de los EE.UU., la violencia usada como instrumento político por parte de las élites colombianas y la dispersión de la izquierda aparecen entre las principales explicaciones de este hecho. Como respuesta a la violencia estatal y ante el cierre de los espacios democráticos, una parte de la izquierda se alzó en armas impugnando la legitimidad del régimen, mientras que otra se mantuvo dentro de la institucionalidad a pesar de los riesgos que ello conllevaba. El Estado, decidido a terminar por la fuerza con el alzamiento armado, adoptó una tendencia militarista encaminada a la persecución de las guerrillas, pero que se extendió al conjunto de la izquierda democrática y del movimiento social. Sin embargo, los Diálogos de Paz han abierto la posibilidad de superar la confrontación. Ante la eventual firma de un acuerdo de paz, vuelve a cobrar vigencia el debate sobre la unidad de la izquierda, pero esta vez con un elemento adicional: la posibilidad de que los movimientos políticos que resulten del acuerdo puedan sumarse a la tan anhelada convergencia.

    Full Text Available INTRODUCCIÓN. La fibrilación auricular es la arritmia cardíaca preoperatoria más frecuente entre los pacientes de cirugía cardiovascular. Entre las modalidades de tratamiento se hallan el tratamiento médico, la cardioversión transtorácica o intracardíaca con choque de corriente continua sincronizada, la estimulación (marcapasos, la ablación con catéter y la cirugía, en la cual se incluyen los métodos quirúrgicos propiamente dichos, las técnicas de catéteres para ablación y las técnicas mixtas. MÉTODOS. Se realizó un estudio prospectivo descriptivo de 25 pacientes operados de patología mitral con fibrilación auricular crónica, a los cuales se realizó ablación con radiofrecuencia durante 60 s, con 150 W de energía y control de temperatura de 60 ºC. Se comenzó el procedimiento solamente alrededor de las venas pulmonares y luego se incluyeron estas. A todos los pacientes se les realizó seguimiento posoperatorio por espacio de un año y la eficacia del procedimiento se evaluó en éxito y fracaso. RESULTADOS. La mejor eficacia del tratamiento estuvo relacionada con la menor edad de los pacientes. A medida que el tiempo de evolución de la fibrilación auricular fue mayor, aumentó el ritmo de fracaso del procedimiento y de igual manera ocurrió con el tamaño de la aurícula izquierda. Se observó que, al año, el 76 % de los pacientes se encontraban en ritmo sinusal y ninguna de las complicaciones que se presentaron tuvieron relación con el método en sí. CONCLUSIONES. Consideramos que la ablación con radiofrecuencia intraoperatoria durante el tratamiento quirúrgico de la válvula mitral constituyó un proceder efectivo y seguro en el tratamiento de pacientes con fibrilación auricular crónica asociadaINTRODUCTION.

Neuropraxia of the great auricular nerve (GAN is an uncommon complication of shoulder surgery, with the patient in the beach chair position. We report a case of great auricular neuropraxia associated with direct compression by a horseshoe headrest, used in routine positioning for uncomplicated shoulder surgery. In this case, an arthroscopic approach was taken, under regional anesthesia with sedation in the beach chair position. The GAN, a superficial branch of the cervical plexus, is vulnerable to neuropraxia due to its superficial anatomical location. We recommend that for the procedures of the beach chair position, the auricle be protected and covered with cotton and gauze to avoid direct compression and the position of the head and neck be checked and corrected frequently. Keywords: neuropraxia, anesthesia, arthroscopy, great auricular nerve

    Objective: To present the authors' initial experience of treating auricular arteriovenous malformations(AVMs) with ethanol embolization and to assess the clinical effectiveness of this therapeutic method. Methods: Twenty-two patients with AVMs were enrolled in this study. Through local puncturing or super-selective catheterization the absolute ethanol,or diluted alcohol (based on the pattern of the AVMs), was manually injected into the abnormal vascular plexus of the auricular lesion. The clinical results were estimated with physical examination or angiography at intervals of 3-4 month, and telephone questionnaire was made at monthly intervals for all patients. Results: Thirty-eight ethanol embolization procedures were performed, the amount of ethanol used during the procedure ranged from 4 ml to 65 ml. After the treatment the clinical symptoms were improved, which were manifested as healing of the ulceration, stop of bleeding, disappearing or alleviation of tinnitus. Angiographic examination showed that the abnormal vascular lesion was completely vanished in 9 cases, decreased by 50%-75% in 8 cases and decreased less than 50% in remaining 5 cases. The common complications included irreversible local necrosis and vesiculation. Conclusion: For the treatment of auricular AVMs ethanol embolization is an effective and safe method,which might become the therapy of first choice. (authors)

    Full Text Available El período histórico que va desde mediados de la década del cincuenta a mediados de los setenta, representa uno de los más importantes momentos de la lucha de clases abierta en nuestro país, proceso que fue acompañado por la emergencia de numerosas organizaciones revolucionarias con características novedosas respecto a los tradicionales representantes de la izquierda. Dentro del conjunto de lo que se ha denominado la "izquierda peronista", la indiscutible presencia mayoritaria de los Montoneros, ha opacado la actuación de otras organizaciones, entre ellas las Fuerzas Armadas Peronistas-Peronismo de Base. En este trabajo abordaremos cuestiones referentes a: 1 su evolución político-ideológica; 2 la relación lucha política-lucha sindical - lucha armada; 3 su particular forma organizativa; 4 la manera de resolver la combinación de peronismo y marxismo; y 5 su vinculación con la clase obrera. Veremos que este último punto será el eje sobre el que girarán las demás cuestiones, en razón del objetivo estratégico que se fue perfilando a lo largo de su desarrollo político: del regreso de Perón a la creación de "poder obrero".

It innervates the skin over the external ear, the angle of the mandible and the parotid gland. It communicates with the ansa cervicalis. Great auricular neuralgia is rarely diagnosed in clinical practice and can be refractory. We present a new approach using ultrasound-guided nerve blocks.Case: We present a case of a 41-year-old female with paroxysmal ear pain accompanied by dysautonomia, tingling in the tongue, dysphagia, dysarthria and abdominal symptoms. No significant findings were found on cervical and brain imaging. The patient responded partially to a great auricular nerve block. A combined approach using this block with facet block of C2 and C3 induced a more pronounced and prolonged benefit.Conclusion: Great auricular neuralgia is not often encountered in practice and can be accompanied by symptoms originating from the ansa cervicalis network. A combined approach of nerve blocks can be considered in refractory cases. Keywords: ansa cervicalis, neuropathic pain, facet block, red ear syndrome, great auricular nerve

  16. Neuroprosthetics for Auricular Muscles: Neural Networks and Clinical Aspects

    2018-01-01

    Full Text Available The mammalian external ear houses extrinsic and intrinsic auricular muscles. There are three extrinsic auricular muscles—the posterior, superior, and anterior auricular muscles—and six intrinsic muscles—the helicis major and minor, tragicus, anti-tragicus, transverse and oblique muscles. These muscles have been considered vestigial in humans. However, numerous therapeutic and diagnostic wearable devices are designed to monitor and alleviate the symptoms of neurological disorders, brainstem injuries, emotional states, and auditory functions, by making use of the neural networks of the auricular muscles and their locations, which are easily accessible for ergonomic wearable biomedical devices. They can also serve as a bio-controller of human neuroprosthetics. The functionality of these auricular muscles remains elusive and requires further experimentation for a more in-depth understanding of their anatomy. The aims of this review are (1 to provide a detailed account of the neural networks of the extrinsic and intrinsic auricular muscles, (2 to describe diagnostic and therapeutic functions of these muscles as demonstrated in the current literature, and (3 to outline existing and potential neuroprosthetic applications making use of the auricular muscles and their neural networks.

    Full Text Available El nombre de extrema izquierda, izquierda radical o izquierda revolucionaria agrupa a una serie de organizaciones y partidos que surgen a mediados de los años sesenta del pasado siglo en oposición a la rígida hegemonía que sobre el movimiento comunista internacional ejercía el PCUS. Identificadas como New Left, estas formaciones se distinguen por fijar en el marxismo—leninismo las fuentes revolucionarias de su ideología, su mitificación de la clase obrera y las realidades lejanas, su estructura organizativa marcadamente jerarquizada y centralizada, y su acusada beligerancia hacia la ortodoxia soviética. Las condiciones de represión, clandestinidad y aislamiento propias de las dictaduras que padecen, agudizan las similitudes de las izquierdas revolucionarias de Portugal y España, sobre las que también se deja sentir la impronta de sus procesos específicos. En su evolución también se observan numerosos paralelismos: una pérdida generalizada de protagonismo a medida que avanza el proceso de transición hacia la democracia parlamentaria, cuya instauración acarreará la crisis y rápido declive de la mayor parte de sus formaciones partidarias. No obstante, en la década de los noventa, una vez descartada la opción de la lucha armada y sorteado el peligro de la sectarización, algunas organizaciones de la antigua izquierda radical peninsular experimentan unos cambios tan profundos que llegan a dibujar dos perfiles alternativos de otra nueva izquierda: en uno los revolucionarios se convierten en alternativos, en el otro los radicales se transforman en parlamentarios con éxito.

    Orbital floor fractures of varying sizes commonly occur after orbital injuries and remain a serious challenge. Serious complications of such fractures include enopthalmos, restriction of extraocular movement, and diplopia. There is a dearth of literature that can be applied widely, easily, and successfully in all such situations, and therefore there is no consensus on the treatment protocol of this pathology yet. Autogenous grafts and alloplastic and allogenic materials with a wide variety of advantages and disadvantages have been discussed. The value of preoperative and postoperative ophthalmological examination should be standard of care in all orbital fracture patients. An ideal reconstructed orbital floor fracture should accelerate the restoration of orbital function with acceptable cosmetic results. Management parameters of orbital fractures such as timing of surgery, incision type, and implant materials, though widely discussed, remain controversial. In this study, 55 patients with orbital floor fractures surgically reconstructed with conchal cartilage grafts between 2008 and 2014 were retrospectively evaluated. Complications and long-time follow-up visit results have been reported with clinical and radiographic findings. The aim of this study was to present the authors' clinical experiences of reconstruction of blow-out fractures with auricular conchal graft and to evaluate the other materials available for use.

    Full Text Available Deqi sensation, a psychophysical response characterized by a spectrum of different needling sensations, is essential for Chinese acupuncture clinical efficacy. Previous research works have investigated the component of Deqi response upon acupuncture on acupoints on the trunk and limbs. However, the characteristics of Deqi sensations of transcutaneous electrical nerve stimulation (TENS on auricular points are seldom reported. In this study, we investigated the individual components of Deqi during TENS on auricular concha area and the superior scapha using quantitative measurements in the healthy subjects and depression patients. The most striking characteristics of Deqi sensations upon TENS on auricular points were tingling, numbness, and fullness. The frequencies of pressure, warmness, heaviness, and soreness were relatively lower. The dull pain and coolness are rare. The characteristics of Deqi were similar for the TENS on concha and on the superior scapha.

    Acupuncture has been shown to influence skin perfusion and the subjective cold perception threshold. Therefore, we hypothesized that auricular electroacupuncture (EA) might reduce symptoms in primary Raynaud's phenomenon (PRP). Twenty-six patients with PRP received 6 cycles of auricular EA. After 3, 6 and 24 weeks attack frequency and severity were reevaluated using standardized questionnaires and a visual analogue scale (VAS). Skin temperature was assessed by infrared thermography and laser Doppler perfusion imaging was used to determine skin perfusion. Compared to baseline we found a significant reduction of attack frequency after 3 (p = 0.001) and 6 weeks (p < 0.001) of auricular EA. This improvement sustained following cessation of EA, after 24 weeks (p < 0.001). Furthermore, attack associated pain was reduced after 3 (p = 0.003), 6 (p = 0.003) and 24 weeks (p = 0.001) of treatment, while skin temperature and skin perfusion did not change significantly throughout the study period. Auricular EA reduces symptoms by means of frequency and severity of attacks in PRP but has no influence on skin perfusion and skin temperature.

    Introduction  Several surgical techniques and modifications have been described to reduce the high recurrence rate after excision of preauricular sinus. Objectives  The aim of this study is to review the literature regarding surgical approaches for preauricular sinus. Data Synthesis  We performed searches in the LILACS, MEDLINE, SciELO, PubMed databases and Cochrane Library in September, 2015, and the key words used in the search were "preauricular sinus," "sinusectomy," "supra-auricular approach," "methylene blue," and/or "recurrence." We revised the results of 17 studies, including 1270 preauricular sinuses that were surgically excised by sinusectomy in 937 ears and by supra-auricular approach in 333 ears. Recurrence with supra-auricular was 4 (1.3%) while sinusectomy was 76 (8.1%) with significant difference ( p  Supra-auricular approach had significantly less recurrence rate than tract sinusectomy approaches. Thus, it could be regularly chosen as the standard procedure for preauricular sinus excision. As such, it would be helpful for surgeons to be familiar with this approach.

    Conclusion: In postoperative auricular perichondritis after an endaural approach tympanoplasty, wide excision seems to be a better choice to treat this problem. Repeated limited excisions could result in ear deformity. Cartilage exposure during chronic ear surgery should be avoided, and early precautions after operation should be taken in order to prevent complications.

    Hypertension is an important risk factor of cardiovascular disease (CVD), which is associated with premature death, myocardial infarction, stroke, peripheral vascular disease, and renal disease. The goal of the present study was to use a randomized controlled clinical trial to explore and compare the effectiveness of abdominal and auricular acupuncture on blood pressure in 440 subjects with and without obesity. Four hundred participants were recruited and randomized to one of four groups: cases and controls receiving auricular acupuncture (204 subjects) and cases and controls receiving abdominal electroacupuncture (196 subjects). Blood pressure and anthropometric parameters were measured before and after the intervention period. In order to match the initial diet of the groups, participants were required to follow an isocaloric diet for two weeks before the trial, and a low-calorie diet for 6 weeks during the intervention period. We observed a significant time dependent improvement in the systolic blood pressure measurements in the abdominal intervention group, although this improvement was more pronounce in the first period of study. Of note, in the auricular intervention group, a significant increasing in the level of SBP was detected. Importantly no statistically significant changes were found in the corresponding sham groups. Our findings demonstrated that abdominal electro-acupuncture for 6 weeks reduced both systolic and diastolic blood pressure and auricular acupuncture had a short-term adverse effect on both SBP and DBP.

    Treatment by auricular acupuncture has a long history. Ear-acupoint research has been advancing step by step in China and also in Europe. Auricles are rich in nerves, therefore a close relationship with different functions of the human body has been proved by the research teams of the two main authors of this article from China and Austria. In recent years, great progress has been made in the research of regulating human body functions through electroacupuncture at the auricular branch of the vagus nerve, which is part of auricular acupuncture therapy. It is well known that the auricular branch of the vagus nerve is the only peripheral pathway to the cerebral cortex. Studies of the Chinese team on hypertension, diabetes, epilepsy and depression have shown that the mechanism of auricular vagus nerve stimulation (VNS) may be comparable with cervical VNS in terms of pathways. Auricular VNS has a broad clinical application prospect.

    Current biomaterials for auricular replacement are associated with high rates of infection and extrusion. The development of new auricular biomaterials that mimic the mechanical properties of native tissue and promote desirable cellular interactions may prevent implant failure. A porous 3D nanocomposite scaffold (NS) based on POSS-PCU (polyhedral oligomeric silsesquioxane nanocage into polycarbonate based urea-urethane) is developed with an elastic modulus similar to native ear. In vitro biological interactions on this NS reveal greater protein adsorption, increased fibroblast adhesion, proliferation, and collagen production compared with Medpor (the current synthetic auricular implant). In vivo, the POSS-PCU with larger pores (NS2; 150-250 μm) have greater tissue ingrowth (≈5.8× and ≈1.4 × increase) than the POSS-PCU with smaller pores (NS1; 100-50 μm) and when compared to Medpor (>100 μm). The NS2 with the larger pores demonstrates a reduced fibrotic encapsulation compared with NS1 and Medpor (≈4.1× and ≈1.6×, respectively; P < 0.05). Porosity also influences the amount of neovascularization within the implants, with no blood vessel observed in NS1 (12 weeks postimplantation). The lack of chronic inflammatory response for all materials may indicate that the elastic modulus and pore size of the implant scaffold could be important design considerations for influencing fibrotic responses to auricular and other soft tissue implants. © 2016 WILEY-VCH Verlag GmbH & Co.

    To raise awareness of the potential hazard of auricular burns associated with operating microscope use during otologic surgery. Retrospective case series and summary of the Food and Drug Administration's (FDA) Manufacturer and User Facility Device Experience (MAUDE) database of voluntary adverse event reports pertaining to microscope related auricular thermal injuries. All patients who sustained auricular burns while using the operating microscope during otologic surgery at 2 tertiary academic referral centers. Surgical procedure, microscope model, intensity of illumination, length of procedure, focal length, location and severity of burn, and patient outcome. A total of 4 microscope-related auricular thermal injuries were identified from the authors' institutions. Additionally, 82 unique cases of soft tissue burns associated with the use of an operative microscope have been voluntarily reported to the FDA since 2004. A disproportionately large percent (∼ 30%) of these occurred within the field of otology, the majority of which were during tympanoplasty or tympanomastoidectomy procedures at focal length distances of 300 mm or less with xenon light source microscopes. Simultaneous advancements in light delivery technologies and lens optics have continued to improve the efficiency of the operating microscope; however, these improvements also increase the potential for thermal injuries. Although rare, a review of the FDA MAUDE database suggests that microscope-related soft tissue burns occur more frequently in otology than any other surgical specialty. A variety of factors may help explain this finding, including the unique anatomy of the external ear with thin skin and limited underlying adipose tissue. Preventative measures should be taken to decrease the risk of thermal injuries including use of the lowest comfortable light intensity, adjusting the aperture width to match the operative field, frequent wound irrigation, and covering exposed portions of the pinna

    Auricular acupuncture treatments are becoming increasingly available within military treatment facilities, resulting in an expansion of nonpharmacologic treatment options available to veterans with posttraumatic stress disorder (PTSD). This study aimed to explore the self-reported benefits of auricular acupuncture treatments for veterans living with PTSD. A qualitative research methodology, thematic content analysis, was used to analyze data. Seventeen active duty veterans with PTSD provided written comments to describe their experiences and perceptions after receiving a standardized auricular acupuncture regimen for a 3-week period as part of a pilot feasibility study. A variety of symptoms experienced by veterans with PTSD were improved after receiving auricular acupuncture treatments. Additionally, veterans with PTSD were extremely receptive to auricular acupuncture treatments. Four themes emerged from the data: (1) improved sleep quality, (2) increased relaxation, (3) decreased pain, and (4) veterans liked/loved the auricular acupuncture treatments. Veterans with PTSD reported numerous benefits following auricular acupuncture treatments. These treatments may facilitate healing and recovery for veterans with combat-related PTSD, although further investigations are warranted into the mechanisms of action for auricular acupuncture in this population. © The Author(s) 2015.

    The objective of this study was to report on the survival rate of 16 patients treated with extraoral implants in the auricular region, analyze treatment outcomes, and discuss important clinical variables encountered during treatment. Sixteen patients who received extraoral dental implants to retain auricular prostheses between 1987 and 2003 were followed retrospectively. The variables recorded were gender, initial diagnosis, number and size of implants, implant placement date, age at implant placement, history of radiation to the treated field, abutment size, design of initial prosthesis, age of initial prosthesis (when a remake was indicated), date of prosthesis delivery, soft tissue response, grafting procedure, date of last follow-up, and complications. All patients were thoroughly evaluated presurgically by the reconstruction team, which consisted of prosthodontists, a facial prosthetist, and an otolaryngologist. Surgical templates were used for all patients. The criteria for success of the prostheses included marginal accuracy, overall stability and function, symmetry/position, texture, color stability, and patient acceptance. Thirty-nine implants were placed in 16 patients. All 16 patients were completely satisfied with their reconstructions. No surgical complications, implant failures, or prosthetic failures were encountered. Therefore, the survival rate was 100%. Three patients (18.75%) had grade 0, seven (43.75%) had grade 1, five (31.25%) had grade 2, and one (6.25%) had grade 3 soft tissue inflammation. The inflammation completely resolved in 7 of the 13 patients (54%) with hygiene reinforcement or soft tissue reduction. The survival rate for bone-anchored titanium implants and prostheses was 100%. Bone-anchored titanium implants provided the 16 patients in this study with a safe, reliable, adhesive-free method to anchor auricular prostheses with recovery of normal appearance. Under the guidance of an appropriate implant team, proper positioning of

    Full Text Available Introducción y Objetivos: La incidencia de queloides auriculares es cada vez mayor. Su alta frecuencia de recidiva es de gran interés, por ello su extirpación quirúrgica se asocia a otras terapias como radioterapia, corticoides, crioterapia, láser, presoterapia, etc. La presoterapia resulta un método efectivo, sencillo y accesible. Material y Método: Realizamos un estudio prospectivo, experimental, sobre 11 casos de queloides auriculares tratados con resección quirúrgica seguida de presoterapia usando imanes, tomando en cuenta la presión y fuerza magnética ejercida. Llevamos a cabo seguimiento de los casos entre 4 y 6 meses. Empleamos las pruebas de Mann-Whitney y Coeficiente Lineal de Pearson. Determinamos la tasa de recurrencia y realizamos un analisis de regresión para el estudio de la escala de Valor Análoga del Dolor (EVA. Resultados: La tasa libre de recurrencia fue del 90.91%. No hubo ningún tipo de complicación. En cuanto a la EVA, observamos una ascendente tolerancia a la terapia con imanes auriculares a través del tiempo. Conclusiones: El protocolo de uso de imanes que presentamos es un excelente tratamiento coadyuvante. El magnetismo parece cumplir un papel fundamental en la remodelación y organización de las fibras de colágeno de las cicatrices postoperatorias, añadiendo una efectividad mayor a la presoterapia.

Se presenta un caso clínico en el que el intervencionismo coronario precoz consiguió la cardioversión a ritmo sinusal de una fibrilación auricular en el curso de un infarto agudo de miocardio, posteriormente se discute la estrategia a seguir en torno a la arritmia en un paciente con buena evolución clínica tras el suceso. / Abstract: Atrial fibrillation is the most common arrhythmia in the periacute myocardial infarc-tion period, although its presence associated only to the acute phase of ischemia and its immediate cessation after early and effective revascularization is anecdotal in the literature, with a consequent lack of evidence for further treatment. A clinical case in which early coronary intervention managed to achieve a cardioversion of atrial fibrillation to sinus rhythm during an acute myocardial infarction is reported. Subsequently, it is discussed the strategy that must be followed with regard to arrhythmia in a patient with good clinical outcome after the event.

    In Western medicine, the long history of the ear syringe dates back at least to the end of the 1st millennium BCE; but the corresponding Ancient Greek word surinx designates another tool. Other Greek and Latin words and phrases, in particular auricular clyster, otenchytes, and pyoulcos, were known as names of the ear syringe until modern times. The aim of this article is to study the Greek and Latin words and phrases referred to as names of the ear syringe up until modern times before syringe became the standard word. Historical and philological review of ancient Greek and Latin medical literature dealing with the subject. Careful reading of ancient medical texts mentioning these tools shows a variety of shapes and uses: beside the piston-driven syringe, the system of a bladder attached to a catheter remained in use throughout Antiquity; the otenchytes, being a piston-driven syringe, obviously was not used to squirt the liquid when the remedy put inside was warmed by a flame; the piston-driven pyoulcos is most likely of greater size, and never linked with ear care in Antiquity. Latin auricular clyster and Greek otenchytes and pyoulcos, in the few ancient texts in which they occur, designate tools of a large variety of shapes and uses, significantly different from Heron's description of piston-driven pyoulcos.

    Full Text Available La fibrilación auricular es la arritmia más frecuente y se relaciona con una alta tasa de accidente cerebrovascular y embolia sistécmica. La terapia establecida tanto para prevención primaria como secundaria es la anticoagulación con warfarina, antagonista de la vitamina K. Existen escalas que predicen el riesgo tromboembólico y la probabilidad de beneficiarse de terapia antitrombótica. El CHADS2 ha sido la más simple y ampliamente utilizada, pero actualmente el CHA2DS2-VASc ha incorporado otros factores de riesgo, otorgando una mejor estratificación. El estrecho margen terapécutico de la warfarina y la interacción con fármacos y alimentos requiere controles seriados de la intensidad de la anticoagulación, limitando su uso clínico. Han aparecido nuevos anticoagulantes que ofrecen ventajas sobre los antagonistas de vitamina K. Estos actúan en dos sitios distintos de la cascada de la coagulación: inhibiendo directamente la trombina como el dabigatran, o el factor X activado como el rivaroxaban, apixaban, edoxaban y betrixaban. Estos nuevos fármacos han ido reemplazando a la warfarina y ya están incluidos en las guías de manejo de fibrilación auricular no valvular.

    The international standardization of auricular acupuncture points (AAPs) is an important basis for auricular therapy or auricular diagnosis and treatment. The study on the international standardization of AAPs has gone through a long process, in which the location method is one of the key research projects. There are different points of view in the field of AAPs among experts from different countries or regions. By only analyzing the nine representative location methods, this paper tried to offer a proper location method to locate AAPs. Through analysis of the pros and cons of each location method, the location method applied in the WFAS international standard of AAPs is thoroughly considered as an appropriate method. It is important to keep the right direction during developing an International Organization for Standardization (ISO) international standard of auricular acupuncture points and to improve the research quality of international standardization for AAPs.

    2013-01-01

    Full Text Available Background: Ideal placement of bone integrated implants to retain a prosthesis is critical for a successful final prosthetic restoration. Several sources have described the importance and use of surgical templates for the optimal placement of extraoral implants. The literature is replete with information explaining the use of surgic al templates for intraoral implant placement. Indeed, correct placement of implants facilitates creating a prosthesis that functions well and looks natural. To ensure proper implant placement, considerable effort should go into pre-surgical planning. It is clear that extraoral surgical templates aid in proper implant placement, yet the literature describing fabrication is limited. This article describes different methods for fabrication of surgical template for placement of implants for an auricular prosthesis.

    Full Text Available La fibrilación auricular es la taquiarritmia cardíaca más frecuente. Su incidencia aumenta con la edad, presentándose en un 1.5% entre los 50 a 59 años, y en un 8-10% entre los 80 a 89 años. Esta arritmia incrementa en cinco veces el riesgo de sufrir un evento cerebrovascular isquémico cardioembólico y causa el 15% de todos los accidentes cerebrovasculares isquémicos. Su manejo se enfoca en la prevención de los fenómenos tromboembólicos y el control de la frecuencia y ritmo cardíaco. El tratamiento anticoagulante ha demostrado ser la principal herramienta en la prevención de eventos cardioembólicos. Aunque las complicaciones hemorrágicas por el tratamiento son esperables y aumentan con la edad, el beneficio de usar anticoagulación sobrepasa por mucho al riesgo de sangrado. Precisamente debido a la heterogeneidad clínica de esta arritmia y a la dificultad de establecer un tratamiento adecuado para cada caso en particular, el American College of Cardiology, la American Heart Association, la European Society of Cardiology y el American College of Chest Physicians han establecido guías para mejorar el tratamiento de estos pacientes. La revisión de esta enfermedad y de las directrices propuestas puede facilitar y mejorar notablemente el tratamiento de los pacientes con fibrilación auricular.

    Auricular melanomas are now considered less aggressive than originally thought, but those located on the conchal bowl and posterior ear can create particular challenges for reconstruction. Given the paucity of cases, no standardized recommendations exist for tumor resection. In this study, we provide a pathologic basis in support of conservative tumor resection along the perichondrial plane. Case series with review of pathology and medical records. Academic tertiary referral center. We retrospectively reviewed all ear melanomas from the archives of Yale Dermatopathology and Surgical Pathology laboratories between 1987 and 2009. Cases of melanoma in situ or malignant melanoma of the earlobe were excluded. Fifty-one cases were included in the study. Patients' age ranged from 26 to 94 years, with a mean (SD) of 58.9 (17.5) years. The male to female ratio was of 5.4:1. Melanomas were distributed similarly between right and left ears, at 52% and 48%, respectively. The most common location was the helix (74.5%). The Breslow depth ranged from 0.19 to 11 mm, with a mean (SD) of 1.64 (1.6) mm. The lesion-perichondrium distance ranged from 0 to 8.12 mm, with a mean (SD) of 1.11 (1.1) mm. Notably, the perichondrium was not invaded in any of the cases. Based on the histopathologic characteristics of our cases, the perichondrium can be considered an effective barrier and therefore a biological plane for wide local resection in some cases of auricular melanomas, allowing surgeons to achieve negative margins without necessarily sacrificing underlying cartilage.

    The characteristics and principles of acupoint selection in auricular plaster therapy for hypertension were explored. By searching CNKI (search time from 1950 to November of 2015), VIP database (search time from 1989 to November of 2015) and WanFang Database (search time from 1983 to November of 2015), the clinical research literature regarding auricular plaster therapy for hypertension was collected, and frequency statistics method was used for analysis. As a result, totally 117 articles were included. The auricular points with frequency from high to low were Jiangyagou, Shenmen (TF 4 ), Gan (CO 12 ), Xin (CO 15 ), Shen (CO 10 ), Jiaogan (AH 6a ), Pizhixia (AT 4 ), Jiangyadian and Neifenmi. The TCM syndromes with frequency from high to low were excessive accumulation of phlegm-dampness syndrome, upper hyperactivity of liver yang syndrome, yin deficiency and yang hyperactivity syndrome and excessive liver-fire syndrome. In conclusion, based on cross-reference of TCM and modern medicine combination of zangfu and meridians differentiation and valuing the auricular points from clinical experience, the auricular plaster therapy for hypertension was characterized with "treating the principal and subordinate symptoms simultaneously and respectively" and "differentiation-based selection of auricular points to regulate zangfu ", which could fully take the anti-hypertension advantages of non-pharmacotherapy.

    This study aimed to describe a "bolsterless" technique for managing auricular hematomas in professional fighters. Eight auricular hematomas were drained under local anesthesia by incising along an anatomical auricular crease. After evacuation of the hematoma and copious irrigation, the resultant skin flap was replaced in anatomical position, and through-and-through absorbable mattress sutures were used to secure the flap in place. Incision sites were left open and dressed with antimicrobial ointment. No bolsters were placed. The patients were given 1 week of oral antibiotic therapy. All 8 hematomas resolved without further intervention. All 8 ears returned to their preinjury cosmetic state. Fighters were able to return to training within a week of the initial injury. No postoperative infections or other complications were noted. In contrast to wrestlers, mixed martial artists (also called "ultimate fighters") do not routinely wear protective head gear. As a result, they are at increased risk of recurrent auricular hematomas, often resulting in severe auricular deformities (cauliflower ear). These patients are anxious to return to training and fighting, and are reluctant to wear a bolster after repair. At their urging, we agreed to attempt this bolsterless technique. Although 2 patients in this series already had a significant cauliflower ear before being treated for the current hematoma, in all cases the auricle returned to its preinjury condition. Bolsterless treatment using mattress sutures and cosmetically placed incisions represents a successful technique for management of auricular hematomas in this population.

    Full Text Available Dentro del ideario anarquista podemos encontrar muchísimas vertientes ideológicas diferentes que nos hacen imposible dar una definición unívoca de esta corriente de pensamiento o, mejor dicho, de vida. Podemos señalar, sin embargo, una característica común a todo ideal ácrata: la oposición al Estado. Es posible señalar también, en un anarquismo puro, el respeto de los tres pilares fundadores de la Revolución Francesa, pero con una dinámica diferente: en lugar de considerarlos aisladamente, para el anarquismo puro, el trinomio debe funcionar como un todo único. Esto da lugar al triángulo virtuoso de libertad, igualdad y fraternidad; sin embargo, no todos los anarquistas defienden íntegramente este triángulo. Hay autores que, por ejemplo, no prestan atención a la igualdad. Siguiendo el esquema de distinción política que da Norberto Bobbio en Derecha e izquierda podemos realizar una diferenciación entre los anarquistas de ambos lados del abanico político. Esta diferencia la marca, según Bobbio, la aspiración, o no, a una sociedad igualitaria. En consecuencia, serán de izquierda aquellos anarquistas que defiendan la igualdad y, por ende, el triángulo virtuoso. Serán anarquistas de derecha, en cambio, aquellos que deseen la abolición del Estado pero haciendo caso omiso de si la sociedad se vuelve o no igualitaria.

    Advances in staged total auricular reconstruction have resulted in improved anterior auricular appearance; however, satisfactory postreconstruction esthetics of the retroauricular fold remain challenging. The postauricular appearance of the reconstructed ear depends largely upon optimizing the covering material. When used as the covering soft tissue for ear elevation, a flap containing primarily the upper portion of the retroauricular fascia has potential advantages over the conventional book cover-type retroauricular fascia flap. We developed a geometrically designed, posterosuperior auricular fascia flap to replace the conventional retroauricular fascia flap for ear elevation. During the second-stage operation, the posterosuperior auricular fascia flap is rotated downward and turned over to wrap around the inner strut and entire posterior auricular surface. Compared to the conventional book cover-type retroauricular fascia flap, the novel posterosuperior auricular fascia flap was easier to harvest and the operative time significantly decreased (110.3 vs. 121.5 min, p fascia flap improves ear elevation. Compared to the conventional book cover-type retroauricular fascia flap, this covering tissue is easier to perform so the surgical time is decreased. It was highly vascularized, well defined, thinner, and yields reliable results. Thus, favorable postauricular surface results can be achieved during auricular reconstruction by using the modified fascia flap.

Durante la primera etapa (1971-1984, exhibía un programa democrático y reformista mientras que la ideología de la mayoría de los partidos que la integraban subestimaba el papel de la democracia liberal y aspiraba a instaurar lo más pronto posible el socialismo. La segunda etapa (1985-1994 es un tiempo de transición ideológica, impulsada por factores domésticos y exógenos. Este proceso desemboca en la creación del Encuentro Progresista (1994, constituido sobre la base de la alianza entre el Frente Amplio y nuevos aliados provenientes de los partidos tradicionales. A partir de esa fecha, y durante la década siguiente, la izquierda uruguaya siguió mutando, abandonando la mayor parte de sus propuestas programáticas de comienzos de la década de 1970 y convirtiéndose en un partido catch-all y socialdemócrata.ABSTRACT: Focusing on the ideology of the Uruguayan left, we recognize three stages in its evolution since the creation of the Frente Amplio in 1971 until its recent electoral triumph (2004. During the first stage (1971-1984, the FA promoted a democratic and reformist program. Whereas the ideology of the majority of its different fractions underestimated the idea of liberal democracy, and aspired to reach socialism as soon as possible. The second stage (1985-1994 was a time of ideological transition, influenced by domestic changes and international contexts, culminating on the creation of the Encuentro Progresista (1994, an alliance between FA and new partners coming from traditional parties. During the next last decade (1995-2004, the Uruguayan left continued its transformation, leaving behind most of its programmatic proposals of the early seventies and becoming a social-democratic catch-all party.

    The accurate reproduction of the form and surface details of missing body structures is an essential part of any successful prosthetic rehabilitation. It helps mask the prosthesis and gives confidence to the patient. This clinical report details the integration of multiple in-house digital technologies of laser scanning, rapid prototyping, and digital color scanning and formulating to improve the shape, texture, orientation, and color of auricular prostheses for 3 patients with missing unilateral ears. A structured light laser scanner was used to digitize the patient's nondefect ear. The digitized data were then manipulated in specialist software and mirrored to reflect the opposing side. A rapid prototyping machine was used to manufacture a 3-dimensional (3D) model of the soft tissue required. This 3D mirrored ear model allowed the accurate reproduction of missing soft tissue. A color spectrometer was used to accurately reproduce the skin tones digitally and physically. Copyright © 2014 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc.

    This study aimed to investigate the impact on patients' quality of life of great auricular nerve sacrifice during parotidectomy. A retrospective review was conducted of 191 consecutive patients who underwent parotidectomy with great auricular nerve sacrifice between 2006 and 2011. Residual sensory dysfunction and its impact on quality of life was analysed using an eight-item quality of life survey. In all, 139 out of 191 patients (72.8 per cent) experienced one or more abnormal sensations in the ear or neck region after surgery. There was a moderate inverse correlation between the number of abnormal sensations and time elapsed since surgery. Moreover, the degree of discomfort correlated significantly with the frequency of symptom occurrence (p Sacrifice of the great auricular nerve has only a small impact on patient quality of life; their daily activities are not significantly affected.

  16. Growth factor stimulation improves the structure and properties of scaffold-free engineered auricular cartilage constructs.

    Directory of Open Access Journals (Sweden)

    Renata G Rosa

    Full Text Available The reconstruction of the external ear to correct congenital deformities or repair following trauma remains a significant challenge in reconstructive surgery. Previously, we have developed a novel approach to create scaffold-free, tissue engineering elastic cartilage constructs directly from a small population of donor cells. Although the developed constructs appeared to adopt the structural appearance of native auricular cartilage, the constructs displayed limited expression and poor localization of elastin. In the present study, the effect of growth factor supplementation (insulin, IGF-1, or TGF-β1 was investigated to stimulate elastogenesis as well as to improve overall tissue formation. Using rabbit auricular chondrocytes, bioreactor-cultivated constructs supplemented with either insulin or IGF-1 displayed increased deposition of cartilaginous ECM, improved mechanical properties, and thicknesses comparable to native auricular cartilage after 4 weeks of growth. Similarly, growth factor supplementation resulted in increased expression and improved localization of elastin, primarily restricted within the cartilaginous region of the tissue construct. Additional studies were conducted to determine whether scaffold-free engineered auricular cartilage constructs could be developed in the 3D shape of the external ear. Isolated auricular chondrocytes were grown in rapid-prototyped tissue culture molds with additional insulin or IGF-1 supplementation during bioreactor cultivation. Using this approach, the developed tissue constructs were flexible and had a 3D shape in very good agreement to the culture mold (average error <400 µm. While scaffold-free, engineered auricular cartilage constructs can be created with both the appropriate tissue structure and 3D shape of the external ear, future studies will be aimed assessing potential changes in construct shape and properties after subcutaneous implantation.

    A new canine auricular acupuncture point for the treatment for epilepsy is introduced. The new acupoint was used with a previously reported canine auricular acupoint (van Neikerk and Eckersley, 1988) for the treatment of epilepsy in five dogs. The testimonial results of these five cases indicate that the technique is worthy of scientific investigation, and controlled research is proposed. Only testimonial evidence currently supports its application, yet this innocuous treatment is recommended for use in all cases of canine epilepsy. The traditional Chinese medical explanation for the treatment is described, and hypothetical Western physiology is presented.

    Implant-retained auricular prostheses are a successful prosthetic treatment option for patients who are missing their ear(s) due to trauma, oncology, or birth defects. The prosthetic ear is aesthetically pleasing, composed of natural looking anatomical contours, shape, and texture along with good color that blends with surrounding existing skin. These outcomes can be optimized by the integration of digital technologies in the construction process. This report describes a sequential process of reconstructing a missing left ear by digital technologies. Two implants were planned for placement in the left mastoid region utilizing specialist biomedical software (Materialise, Belgium). The implant positions were determined underneath the thickest portion (of anti-helix area) left ear that is virtually simulated by means of mirror imaging of the right ear. A surgical stent recording the implant positions was constructed and used in implant fixtures placement. Implants were left for eight weeks, after which they were loaded with abutments and an irreversible silicone impression was taken to record their positions. The right existing ear was virtually segmented using the patient CT scan and then mirror imaged to produce a left ear, which was then printed using 3D printer (Z Corp, USA). The left ear was then duplicated in wax which was fitted over the defect side. Then, it was conventionally flasked. Skin color was digitalized using spectromatch skin color system (London, UK). The resultant silicone color was mixed as prescribed and then packed into the mold. The silicone was cured conventionally. Ear was trimmed and fitted and there was no need for any extrinsic coloring. The prosthetic ear was an exact match to the existing right ear in shape, skin color, and orientation due to the great advantages of technologies employed. Additionally, these technologies saved time and provided a base for reproducible results regardless of operator.

    Auricular nerve stimulation has been proven effective in different diseases. We investigated if a conservative therapeutic alternative for claudication in peripheral arterial occlusive disease (PAD) via electroacupuncture of the outer ear can be established. In this prospective, double-blinded trial an ear acupuncture using an electroacupuncture device was carried out in 40 PAD patients in Fontaine stage IIb. Twenty patients were randomized to the verum group using a fully functional electroacupuncture device, the other 20 patients received a sham device (control group). Per patient, eight cycles (1 cycle = 1 week) of electroacupuncture were performed. The primary endpoint was defined as a significantly more frequent doubling of the absolute walking distance after eight cycles in the verum group compared to controls in a standardized treadmill testing. Secondary endpoints were a significant improvement of the total score of the Walking Impairment Questionnaire (WIQ) as well as improvements in health related quality of life using the Short Form 36 Health Survey (SF-36). There were no differences in baseline characteristics between the two groups. The initial walking distance significantly increased in both groups (verum group [means]: 182 [95 % CI 128-236] meters to 345 [95 % CI 227-463] meters [+ 90 %], p < 0.01; control group [means]: 159 [95 % CI 109-210] meters to 268 [95 % CI 182-366] meters [+ 69 %], p = 0.01). Twelve patients (60 %) in the verum group and five patients (25 %) in controls reached the primary endpoint of doubling walking distance (p = 0.05). The total score of WIQ significantly improved in the verum group (+ 22 %, p = 0.01) but not in controls (+ 8 %, p = 0.56). SF-36 showed significantly improvements in six out of eight categories in the verum group and only in one of eight in controls.

    Osseointegrated implants have acquired an important role in the prosthetic rehabilitation of patients with craniofacial defects. The main indications are lack of local tissue for autogenous reconstruction, previous reconstruction failure and selection of this technique by the patient. This paper presents a clinical case and discusses indications and advantages of the osseointegrated implant technique for retention of auricular prostheses. Case report, Universidade Federal de São Paulo (UNIFESP). A female patient received three auricular implants after surgical resection of a hemangioma in her left ear. The time taken for osseointegration of the temporal bone was three months. After fabrication of the implant-retained auricular prosthesis, the patient was monitored for 12 months. The clinical parameters evaluated showed good postoperative healing, healthy peri-implant tissue, good hygiene and no loss of implants. Good hygiene combined with thin and immobile peri-implant soft tissues resulted in minimal complications. Craniofacial implant integration appears to be site-dependent; increasing age affects osseointegration in the temporal bone. The frequency of adverse skin reactions in peri-implant tissues is generally low. The surgical technique for rehabilitation using implant-retained auricular prostheses seems to be simple. It is associated with low rates of adverse skin reactions and long-term complications. Prostheses anchored by osseointegrated implants seem to provide better retention than do prostheses supported on spectacle frames, less risk of discoloration through the use of adhesives and better esthetic results than do prostheses anchored in the surgical cavity.

    Replacement of missing ears is a challenging task in which extensive array of materials and techniques have been employed. This article describes a different and simplified procedure for fabricating auricular prostheses very similar to the intact left ear of the patient. A 65-year-old male patient was referred to the Department of Prosthodontics with the loss of the right ear. In this case, the impression was made using hydrocolloid material (alginate) from the both defected and the opposite side. After hardening of the stone casts, a custom-made transparent splint plate was designed for the left auricular side. The splint was reversed and a cast model of the right auricular side was obtained as pouring the dental stone into transparent orthodontic splint. After getting the impression from cast model, conventional wax pattern and try on process was done. Finally, silicone elastomer was polymerized and the retention of the prosthesis acquired with the magnetic attachments. The technique described is economical, conventional, and time-saving. Furthermore, the prosthesis imitates the patient's intact auricular tissue.

    Increased patient acceptance and widespread use have led to a greater demand for refabrication of existing maxillofacial prostheses exhibiting wear and tear. Refabricating an osseointegrated implant-retained silicone auricular prosthesis on the existing Hader bar is a challenging task if it is performed without removing it. Therefore, an attachment level impression method is utilized for the refabrication of a new prosthesis on an existing Hader bar framework without removing it from the patient's defect. This case report discusses a modification of the Mahidol University technique. This modification provides a simple, speedy, and convenient method through which the relation between the metal framework and attachments could be obtained precisely. This precision allowed for easy fabrication of the acrylic housing, which in turn results in better adaptation of the auricular prosthesis to the patient's face. Therefore, this technique offers advantages to both the prosthetist in fabrication and the patient in facilitating him continue to wear his existing implant-retained prosthesis during refabrication process.

    To introduce a novel modified surgical procedure of excision of anterior cartilage of the pseudocyst along with plastic sheet compression for the treatment of auricular pseudocyst and ascertain the effect of the surgical modality of this disease. A retrospective study. Medical college hospital. Eighty-seven auricular pseudocyst patients were subjected to excision of the anterior cartilage of the pseudocyst followed by plastic sheet compression from July 2006 to September 2013. The effects of the operation were evaluated. Eighty patients were males and 7 were females. The median age was 52 years old. The lesions of 86 patients were unilateral and only 1 was bilateral. The clinical features presented a hemispheric painless swelling, which was seen on the ventral side of the auricle, usually the scaphoid and triangular fossa. The average major axis of the pseudocyst was 1.7 ± 0.6 cm. The patients underwent excision of anterior cartilage of the pseudocyst along with plastic sheet compression. The average follow-up period was 51.9 ± 19.1 months. No recurrence was observed with this technique, and the appearance of the auricle was cosmetically acceptable. Our novel modified surgical procedure of excision of anterior cartilage of pseudocyst along with plastic sheet compression is an effective surgical management for the auricular pseudocyst. The advantages of a simple technique, a short-term therapeutic period, and no recurrence made the surgical procedure worth recommending as the definitive treatment of auricular pseudocysts. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

    Full Text Available The goal of this study is to determine the effects of Insulin-Transferrin-Selenium (ITS on proliferation of auricular chondrocytes and formation of engineered cartilage in vitro. Pig auricular monolayer chondrocytes and chondrocyte pellets were cultured in media containing 1% ITS at different concentrations of fetal bovine serum (FBS, 10%, 6%, 2%, 0%, or 10% FBS alone as a control for four weeks. Parameters including cell proliferation in monolayer, wet weight, collagen type I/II/X (Col I, II, X and glycosaminoglycan (GAG expression, GAG content of pellets and gene expression associated with cartilage formation/dedifferentiation (lost cartilage phenotype/hypertrophy within the chondrocyte pellets were assessed. The results showed that chondrocytes proliferation rates increased when FBS concentrations increased (2%, 6%, 10% FBS in ITS supplemented groups. In addition, 1% ITS plus 10% FBS significantly promoted cell proliferation than 10% FBS alone. No chondrocytes grew in ITS alone medium. 1% ITS plus 10% FBS enhanced cartilage formation in terms of size, wet weight, cartilage specific matrices, and homogeneity, compared to 10% FBS alone group. Furthermore, ITS prevented engineered cartilage from dedifferentiation (i.e., higher index of Col II/Col I mRNA expression and expression of aggrecan and hypertrophy (i.e., lower mRNA expression of Col X and MMP13. In conclusion, our results indicated that ITS efficiently enhanced auricular chondrocytes proliferation, retained chondrogenic phenotypes, and promoted engineered cartilage formation when combined with FBS, which is potentially used as key supplementation in auricular chondrocytes and engineered cartilage culture.

    Full Text Available CONTEXT AND OBJECTIVE: Osseointegrated implants have acquired an important role in the prosthetic rehabilitation of patients with craniofacial defects. The main indications are lack of local tissue for autogenous reconstruction, previous reconstruction failure and selection of this technique by the patient. This paper presents a clinical case and discusses indications and advantages of the osseointegrated implant technique for retention of auricular prostheses. TYPE OF STUDY: Case report, Universidade Federal de São Paulo (UNIFESP. METHODS: A female patient received three auricular implants after surgical resection of a hemangioma in her left ear. The time taken for osseointegration of the temporal bone was three months. After fabrication of the implant-retained auricular prosthesis, the patient was monitored for 12 months. RESULTS: The clinical parameters evaluated showed good postoperative healing, healthy peri-implant tissue, good hygiene and no loss of implants. Good hygiene combined with thin and immobile peri-implant soft tissues resulted in minimal complications. Craniofacial implant integration appears to be site-dependent; increasing age affects osseointegration in the temporal bone. The frequency of adverse skin reactions in peri-implant tissues is generally low. CONCLUSION: The surgical technique for rehabilitation using implant-retained auricular prostheses seems to be simple. It is associated with low rates of adverse skin reactions and long-term complications. Prostheses anchored by osseointegrated implants seem to provide better retention than do prostheses supported on spectacle frames, less risk of discoloration through the use of adhesives and better esthetic results than do prostheses anchored in the surgical cavity

    Currently, surgeons approach autogenous microtia repair by creating a two-dimensional (2D) tracing of the unaffected ear to approximate a three-dimensional (3D) construct, a difficult process. To address these shortcomings, this study introduces the fabrication of patient-specific, sterilizable 3D printed auricular model for autogenous auricular reconstruction. A high-resolution 3D digital photograph was captured of the patient's unaffected ear and surrounding anatomic structures. The photographs were exported and uploaded into Amira, for transformation into a digital (.stl) model, which was imported into Blender, an open source software platform for digital modification of data. The unaffected auricle as digitally isolated and inverted to render a model for the contralateral side. The depths of the scapha, triangular fossa, and cymba were deepened to accentuate their contours. Extra relief was added to the helical root to further distinguish this structure. The ear was then digitally deconstructed and separated into its individual auricular components for reconstruction. The completed ear and its individual components were 3D printed using polylactic acid filament and sterilized following manufacturer specifications. The sterilized models were brought to the operating room to be utilized by the surgeon. The models allowed for more accurate anatomic measurements compared to 2D tracings, which reduced the degree of estimation required by surgeons. Approximately 20 g of the PLA filament were utilized for the construction of these models, yielding a total material cost of approximately $1. Using the methodology detailed in this report, as well as departmentally available resources (3D digital photography and 3D printing), a sterilizable, patient-specific, and inexpensive 3D auricular model was fabricated to be used intraoperatively. This technique of printing customized-to-patient models for surgeons to use as 'guides' shows great promise. Copyright © 2017 European

    The external ear is composed of elastic cartilage. Microtia is a congenital malformation of the external ear that involves a small reduction in size or a complete absence. The aim of tissue engineering is to regenerate tissues and organs clinically implantable based on the utilization of cells and biomaterials. Remnants from microtia represent a source of cells for auricular reconstruction using tissue engineering. To examine the macromolecular architecture of microtia cartilage and behavior of chondrocytes, in order to enrich the knowledge of this type of cartilage as a cell reservoir. Auricular cartilage remnants were obtained from pediatric patients with microtia undergoing reconstructive procedures. Extracellular matrix composition was characterized using immunofluorescence and histological staining methods. Chondrocytes were isolated and expanded in vitro using a mechanical-enzymatic protocol. Chondrocyte phenotype was analyzed using qualitative PCR. Microtia cartilage preserves structural organization similar to healthy elastic cartilage. Extracellular matrix is composed of typical cartilage proteins such as type II collagen, elastin and proteoglycans. Chondrocytes displayed morphological features similar to chondrocytes derived from healthy cartilage, expressing SOX9, COL2 and ELN, thus preserving chondral phenotype. Cell viability was 94.6 % during in vitro expansion. Elastic cartilage from microtia has similar characteristics, both architectural and biochemical to healthy cartilage. We confirmed the suitability of microtia remnant as a reservoir of chondrocytes with potential to be expanded in vitro, maintaining phenotypical features and viability. Microtia remnants are an accessible source of autologous cells for auricular reconstruction using tissue engineering strategies.

    Result. As compared to the baseline, only the true TENS group reported a significant reduction in VAS-rest (P=.001, VAS-huff (P=.004, and VAS-cough (P=.001, while no significant reduction in any of the VAS scores was seen in the sham TENS group (all P>.05. In contrast, a small rising trend was observed in the VAS-rest and VAS-huff scores of the control group, while the VAS-cough score remained largely unchanged during the period of the study. A between-group comparison revealed that all three VAS scores of the true TENS group were significantly lower than those of the control group at 15 and 30 minutes after the intervention (all P<.02. No significant between-group difference was observed in PEFR at any point in time. Conclusion. A single session of auricular TENS applied at specific therapeutic points significantly reduced resting (VAS-rest and movement-evoked pain (VAS-huff, VAS-cough, and the effects lasted for at least 30 minutes after the stimulation. The analgesic effects of auricular TENS appeared to be point specific and could not be attributed to the placebo effect alone. However, auricular TENS did not produce any significant improvement in the performance of PEFR.

    Full Text Available Objectives. The objective of this one-group, repeated-measures design was to explore the acceptance of auricular point acupressure (APA to reduce chronic low back pain (CLBP and estimate minimum clinically important differences (MCIDs for pain intensity change. Methods. Subjects received 7-day APA treatment. After appropriate acupoints were identified, vaccaria seeds were carefully taped onto each selected auricular point for 7-day. The Brief Pain Inventory Short Form (BPI was used to collect outcome data. Results. A total of 74 subjects participated in the study. Ten subjects dropped out and the retention rate was 87%. Subjects reported a 46% reduction in BPI worst pain, and over 50% reduction in BPI average pain, overall pain severity and pain interference by the end of study, and 62.5% subjects also reported less pain medication use. The MCIDs for the subscale of BPI ranged from .70 to 1.86 points. The percentage improvement of MCIDs from baseline was between 14.5–24.9%. Discussion. APA appears to be highly acceptable to patients with CLBP. A sham group is needed in order to differentiate the true effects of APA from the possible psychological effects of more frequent visits by the auricular therapist and patients’ expectation of the APA treatment.

    Colonoscopy is the standard procedure for colorectal cancer screening. One of its common complications is abdominal pain. Analgesia has not provided favorable outcomes so various complementary practices have been developed, including auricular acupuncture. In this study, a randomized controlled trial of 56 patients who underwent colonoscopy was conducted to determine the effect of acupuncture on the pain experienced during colonoscopy. Subjects were divided into two groups: The first received acupuncture combined with midazolam and pethidine, while the second were administered placebo puncture in addition to midazolam and pethidine. The median Critical Care Pain Observation Tool (CPOT) score was lower in the auricular acupuncture group than in the placebo puncture group(0.7 [0-4.83] vs. 1.9 [0-6.20] p = 0.010), while there were no significant differences to median Visual Analog Scale (VAS) scores (29 [0-100] vs. 44.5 [0-100] p = 0.147), heart rate changes (-2.58 [14.31] vs.-2.43 [12.28]; p = 0.970), or the mean time to the cecum (16 [8-51] vs. 22 [5-63] p = 0.206). Auricular acupuncture combined with midazolam and pethidine was found to be effective at reducing pain during colonoscopy.

    This study was done to determine the specificity and sensitivity of a commercial Pointer Plus (Point finder) in detecting a region of low skin resistance on the ear. This was a prospective blinded study. The study was done at the Yale New Haven Hospital, New Haven, CT. The subjects were men and women who work at Yale New Haven Hospital. There were no interventions. Correlations were made between self-reported musculoskeletal pain and the detection of low skin resistance on the ear. The positive predictive value for Pointer Plus detecting low skin resistance correlating to the neck region of French auricular map is 0.76 (76%). The positive predictive value for Pointer Plus to detect low skin resistance area correlating to the low back region of French auricular map is 0.25. The positive predictive value for Pointer Plus in detecting any low in skin resistance on the external auricles in patients who complained of more than two musculoskeletal pains is 0.29. The specificity and sensitivity of a commercial Pointer Plus (point finder) in detecting a region of low skin resistance on the ear being unreliable, depending on the correlating area based on a published auricular map. Additional assessments are needed to support the clinical practice.

    Stress and anxiety are experienced by health care providers as a consequence of caregiving and may result in physical, emotional, and psychological outcomes that negatively impact work engagement. The purpose of this study was to determine whether auricular acupuncture can reduce provider anxiety and improve work engagement. Study participants received 5 auricular acupuncture sessions within a 16-week period utilizing the National Acupuncture Detoxification Association protocol for treating emotional trauma. Each participant completed the State-Trait Anxiety Inventory and the Utrecht Work Engagement Scale (UWES-9) prior to their first session and again after their fifth treatment. Significant reductions were found in state and trait anxiety (State-Trait Anxiety Inventory), as well as significant increases in the overall scores on the UWES as compared with baseline. Only the dedication subcategory of the UWES showed significant improvement. Engagement has been linked to increased productivity and well-being and improved patient and organizational outcomes. Providing effective strategies such as auricular acupuncture to support health care providers in reducing anxiety in the workplace may improve engagement.

    A total of 30 students scoring between 12 and 20 on the Test Anxiety Scale who had been exhibiting an anxious state > 24 hours, and 30 normal control students were recruited. Indices of heart rate variability were recorded using an Actiheart electrocardiogram recorder at 10 minutes before auricular pressing, in the first half of stimulation and in the second half of stimulation. The results revealed that the standard deviation of all normal to normal intervals and the root mean square of standard deviation of normal to normal intervals were significantly increased after stimulation. The heart rate variability triangular index, very-low-frequency power, low-frequency power, and the ratio of low-frequency to high-frequency power were increased to different degrees after stimulation. Compared with normal controls, the root mean square of standard deviation of normal to normal intervals was significantly increased in anxious students following auricular pressing. These results indicated that auricular pressing can elevate heart rate variability, especially the root mean square of standard deviation of normal to normal intervals in students with pre-exam anxiety.

    Auricular hematoma and cauliflower deformation of the ear are unique in several respects. Knowledge about it began, in antiquity, through artists, particularly Greek and Roman, and then Japanese in the 18th century with their representation of cauliflower deformation of the ear on sculptures and paintings of pugilists and wrestlers. It is only in the 19th century that physicians began to make substantive progress in understanding this abnormality. It was first thought to be associated with mental disease, but by the beginning of the 20th century, its etiology was recognized as being caused by trauma and was then named auricular hematoma. The second step in the understanding of this affliction was the observation that auricular hematoma progresses toward cauliflower deformation of the ear, which was named cauliflower ear. Recognition of this evolution led to the development of therapies. During the second half of the 20th century, different treatments were developed. They included various hematoma drainage techniques with special bandages to prevent hematoma recurrence and ensuing progression to cauliflower ear. In summary, cauliflower deformation of the ear is an old artistic affliction that has only recently received medical attention.

    The sacroiliac joint (SIJ) is responsible for weight transmission between the spine and lower extremity. However, details of the structure and function of the SIJ remain unclear. In a previous study, we devised a method of quantitatively evaluating the level of degeneration of the SIJ using an age estimation procedure for the auricular surface of the ilium. Our results in that study suggested that the degree of degeneration of the joint surface may be associated with the morphology of the auricular surface of the ilium. In that study, however, the morphology of the auricular surface of the ilium was simplified for analysis, meaning that more detailed investigations were required in future. In the present study, we focused on individual differences in the shape of SIJ and carried out three-dimensional quantitative evaluation of the morphology of the auricular surface of the ilium to ascertain its association with joint degeneration. We produced three-dimensional images of the right auricular surfaces of the ilium of 100 modern Japanese men (age 19-83), and obtained the three-dimensional rectangular coordinates of 11 defined measurement points. We then calculated 16 parameters indicating the morphological characteristics of the auricular surfaces of the ilium from the three-dimensional rectangular coordinates of these measurement points, and used these to perform principal component analysis to investigate trends in the morphology of the auricular surface of the ilium. We found that the morphology of the auricular surface of the ilium could be characterized in terms of (i) size, (ii) concavity of the posterior border and (iii) amount of undulation. An investigation of the correlation between these parameters and age suggested that the amount of undulation of the auricular surface of the ilium tends to diminish with advancing age. In an investigation of the association between morphology of the auricular surface of the ilium and degeneration of the articular surface

    Primary insomnia is a common health issue in the modern world. We conducted a systematic review of the auricular therapy, aiming to evaluate whether there are advantages of auricular acupuncture with seed or pellet attachments for the treatment of primary insomnia. A search of relevant literatures was performed on major medical databases, including Medline, Embase, CENTRAL, CBM, CNKI, VIP, Wanfang Data and so on. Risk of bias evaluation, meta-analysis, sensitivity analysis and evidence rating of all extracted information were conducted also. A total of 1381 records were identified, with 15 studies deemed eligible for the present review. Meta-analyses were conducted in two comparisons separately: participants received auricular acupuncture were more likely to make an improvement in clinical effective rate (RR = 1.40, 95% CI 1.07 to 1.83), sleep duration (MD = 56.46, 95% CI 45.61 to 67.31), sleep efficiency(MD = 12.86, 95% CI 9.67 to 16.06), global score on PSQI (MD = -3.41, 95% CI -3.93 to -2.89), number of awakenings( MD = -3.27, 95% CI -6.30 to -0.25) and sleep onset latency(MD = -10.35, 95% CI -14.37 to -6.33) when compared to sham auricular acupuncture or placebo; while in auricular acupuncture VS medications comparison, a better effective rate (RR = 1.24, 95% CI 1.15 to 1.34), better sleep efficiency(MD = 21.44, 95% CI 16.30 to 26.58), lower PSQI score (MD = -3.62, 95% CI -4.59 to -2.65) and less adverse effect (RR = 0.11, 95% CI 0.04 to 0.26) can be seen also in auricular acupuncture group. Although these results suggested benefits of auricular acupuncture, the overall quality of evidence rated by the GRADE system was low. Statistical analyses of the outcomes revealed a positive effect of auricular acupuncture for primary insomnia. Nonetheless, considering the poor methodological quality, insufficient sample size and possible publication bias, current evidence is not yet adequate to provide a strong support for the use of auricular acupuncture in the

    To explore whether auricular acupressure could improve the absorption of flavanones in the extracts from Citrus aurantium L. in the human body. Ten (10) healthy male volunteers were randomly divided into two groups. Group A was treated with the combination of oral administration of C. aurantium L. extracts and auricular acupressure. Group B was treated only with the oral administration of C. aurantium L. extracts in the same dosage as Group A. After 7 days of treatment, the plasma concentration of naringenin and hesperetin of the two groups were determined using high-performance liquid chromatography. The plasma concentration of naringenin and hesperetin in Group A were significantly higher than Group B. Auricular acupressure at some specific acupoints can significantly improve the absorption of naringenin and hesperetin in the extracts form C. aurantium L. in the human body.

    Conclusiones: La fibrilación auricular no valvular es una de las principales causas del accidente vascular cerebral en nuestros pacientes. Se demuestra que el tratamiento anticoagulante en aquellos pacientes con alto riesgo embolígeno reduce los eventos cerebrovasculares en un 64% y la mortalidad en un 26%. En nuestro medio la mayoría de los pacientes diagnosticados con fibrilación auricular no valvular presentan ese riesgo, pero tenemos un 33% no anticoagulado y un 25% mal controlado con el acenocumarol (un total del 46% de los pacientes. Todo esto implica que casi el 50% de nuestros pacientes con fibrilación auricular no valvular presenten alto riesgo tromboembólico por falta de tratamiento o ineficacia de este.

    Full Text Available La idea de una "Revolución Bolivariana", proclamada por el Presidente de Venezuela Hugo Chávez. puede parecer novedosa y propia del giro actual a la izquierda de varios países sudamericanos. Sin embargo, dicha idea ya era conocida e impulsada en la primera mitad del siglo XX, cuando diferentes movimiemos políticos revolucionarios buscaban el apoyo de Moscú para lograr la toma del poder en los países andinos. Este artículo examina la influencia de la Tercera Internacional sobre los planes de los grupos revolucionarios en los llamados países bolivarianos durante la década de los años veinte y treinta del siglo pasado y señala semejanzas y diferencias entre dicha relación y la que sostiene actualmente el chavismo con algunos movimientos de izquierda venezolanos.

    Full Text Available A fungal endophyte (Neotyphodium coenophialum infects most plants of ‘Kentucky 31’ tall fescue (Lolium arundinaceum and produces ergot alkaloids that cause persistent constriction of the vascular system in grazing livestock. Consequently, animals undergoing this toxicosis cannot regulate core body temperature and are vulnerable to heat and cold stresses. An experiment was conducted to determine if the caudal and auricular arteries in goats (Capra aegagrus hircus vasoconstrict in response to ergot alkaloids.

    The authors describe a previously unreported malformation involving paired, bilaterally symmetrical dermal sinus tracts in the retro-auricular area, both of which passed through the asterion and posterior fossa dura mater to end intracranially. Cranial dermal sinus tracts are congenital lesions that virtually always originate from the midline scalp posteriorly at the external occipital protuberance, anteriorly at the nasion or along the nasal dorsum, or in the posterior parietal midline. A lateral origin is extremely rare, and intracranial extension of a lateral dermal sinus tract has not been reported previously. The authors propose an embryological mechanism to explain the origin of this rare malformation and discuss its management.

Se ha descrito un número importante de factores de riesgo que se asocian con el desarrollo de la misma; en consecuencia, se presentan múltiples complicaciones y aumento de la morbimortalidad. Pese a que existe gran cantidad de evidencia sobre la fibrilación auricular, no hay suficiente literatura que la relacione únicamente con el género femenino. Objetivo: evaluar la literatura existente hasta la fecha sobre fibrilación auricular en la mujer, factores de riesgo, manifestaciones clínicas, enfoque clínico y tratamiento. Conclusiones: la mujer presenta menor incidencia y prevalencia de esta arritmia; así mismo, su edad al momento del diagnóstico es mayor. La hipertensión arterial y la enfermedad valvular son los principales factores de riesgo. Las manifestaciones clínicas tienden a ser más severas y las pacientes tienen un riesgo mayor de ataque cerebrovascular y muerte. Abstract: Introduction: Atrial fibrillation is the most common arrhythmia in men and women worldwide, and its prevalence is increasing. A significant number of risk factors associated with the development of atrial fibrillation have been described, with multiple complications and increased morbidity and mortality occurring as a consequence. Although there is a great deal of evidence regarding atrial fibrillation, there is insufficient literature relating it only to the female gender. Objective: To evaluate the available literature to date on atrial fibrillation in women: risk factors, clinical manifestations, clinical approach and treatment. Conclusions: Women have a lower incidence and prevalence of this arrhythmia, and their age at diagnosis is higher. High blood pressure and valve disease are the main risk factors.

Visto como uma organização “extremista” pela direita e por setores moderados da esquerda, o MIR defendeu a necessidade de preparar o povo para um conflito armado contra as classes dominantes, mesmo durante o governo Allende. Sua posição, definida por Casals (2010 como a “via rupturista”, contrariava a postura hegemônica da UP: o projeto político liderado por Salvador Allende propunha realizar uma transição ao socialismo através da “via sistêmica”, isto é, seguindo os ritos democráticos e a legislação pré-existente. Este artigo analisa os posicionamentos do MIR durante o governo da UP, suas tentativas de radicalizar o restante da esquerda e suas discordâncias em relação aos partidos moderados, diferenças que acabariam persistindo até o golpe de Estado liderado por Augusto Pinochet em 11 de setembro de 1973

    Full Text Available Does Latin America’s left turn matter in media politics? Has ideology any impact on governments’ practices and policies regarding media and journalistic institutions? This essay focuses on the existence of a specific kind of media activism on the part of leftist governments in Latin America. It does so by assessing discourses on the media, direct-communication practices, and media regulation policies. While showing that the current binary distinctions stressing the existence of two lefts – “populist” and “nonpopulist” – obscure important commonalities and continuities, the author demonstrates that institutional and structural constraints account for the differences among the various leftist governments in Latin America. In sum, the paper challenges the prevailing neglect of ideology as a relevant factor in explaining developments in government–media relationships in the region.¿Ha sido relevante el giro a la izquierda en América Latina para la política de medios? ¿Tuvo impacto la ideología en las prácticas y políticas gubernamentales relativas a los medios y las instituciones políticas?

    1997-04-01

    A retrospective study was undertaken to evaluate the outcome of the use of the bone-anchored hearing aid (BAHA) in children. All patients included in the study had bilateral auricular malformations. Previous alternatives had been conventional hearing aids or surgical middle ear reconstruction. Thirty-seven patients under 16 years of age were studied. The most common syndrome in the group was Treacher Collins. Sixteen of the patients had earlier middle ear reconstruction, the results of which did not produce social hearing. Of 40 inserted fixtures to anchor the BAHA, three were lost during the follow-up period because of failed osseointegration. Skin reactions were graded according to a clinical scoring system and were determined to be comparable in number and severity to those of an adult population. All patients in the study considered the BAHA to be superior to earlier bone-conduction devices. It is concluded that the BAHA is an excellent alternative to bone-conduction devices in children with auricular malformations. Middle ear surgery can be postponed until adulthood or abandoned, especially in syndromic patients in whom it is known to be difficult and unpredictable.

    Full Text Available Auricular acupuncture (AA is effective in treating various pain conditions, but there have been no analyses of AA for the treatment of pain after ambulatory knee surgery. We assessed the range of analgesic requirements under AA after ambulatory knee arthroscopy. Twenty patients randomly received a true AA procedure (Lung, Shenmen and Knee points or sham procedure (three non-acupuncture points on the auricular helix before ambulatory knee arthroscopy. Permanent press AA needles were retained in situ for one day after surgery. Post-operative pain was treated with non-steroidal anti-inflammatory ibuprofen, and weak oral opioid tramadol was used for rescue analgesic medication. The quantity of post-operative analgesics and pain intensity were used to assess the effect of AA. The incidence of analgesia-related side effects, time to discharge from the anesthesia recovery room, heart rate and blood pressure were also recorded. Ibuprofen consumption after surgery in the AA group was lower than in the control group: median 500 versus 800 mg, P = 0.043. Pain intensity on a 100 mm visual analogue scale for pain measurement and other parameters were similar in both groups. Thus AA might be useful in reducing the post-operative analgesic requirement after ambulatory knee arthroscopy.

    Full Text Available Increased patient acceptance and widespread use have led to a greater demand for refabrication of existing maxillofacial prostheses exhibiting wear and tear. Refabricating an osseointegrated implant-retained silicone auricular prosthesis on the existing Hader bar is a challenging task if it is performed without removing it. Therefore, an attachment level impression method is utilized for the refabrication of a new prosthesis on an existing Hader bar framework without removing it from the patient's defect. This case report discusses a modification of the Mahidol University technique. This modification provides a simple, speedy, and convenient method through which the relation between the metal framework and attachments could be obtained precisely. This precision allowed for easy fabrication of the acrylic housing, which in turn results in better adaptation of the auricular prosthesis to the patient's face. Therefore, this technique offers advantages to both the prosthetist in fabrication and the patient in facilitating him continue to wear his existing implant-retained prosthesis during refabrication process.

Para ello, se analizan las experiencias del Sindicato Único de Energía Nuclear y de las secciones 11 y 147 del sindicato minero-metalúrgico. En el primer caso, se observa su relación con el movimiento democrático de los trabajadores electricistas y la corriente del nacionalismo revolucionario y en el segundo su vinculación con la organización política Línea Proletaria, de filiación maoísta. Ambas corrientes plantearon estrategias distintas que revivieron la tensión existente en el movimiento obrero mexicano de principios de siglo, entre quienes pensaban que los sindicatos no debían aliarse a partidos políticos y en cambio ejercer la acción directa en el trabajo y quienes abogaban por alianzas políticas, en lo que llamaban acción múltiple. Ambos movimientos confluyeron en el movimiento sindical del periodo, que reclamaba democracia sindical y se manifestaba contra la política de austeridad que el gobierno imponía, así como también por la defensa de los recursos naturales. Por otra parte, se manifestaba el activismo obrero en un medio de una mayor rebeldía que conjuntó a otros grupos sociales, situación que comprueba el ascenso en las luchas de los trabajadores de la industria y en servicios, y su incidencia en la vida política, social y cultural del País.

    Full Text Available Migraine is a chronic disease characterized by intermittent attacks of headache and associated symptoms. It is a disease that affects around 12 to 15% of the general population, most of them being women. The quality of life of these individuals is compromised, causing a major impact on physical, mental and social for those who suffer from migraine. One method of treatment that seems to be effective in relieving the symptoms of menstrual migraine is auricular therapy. The purpose of this study was to evaluate the quality of life of patients with migraine related to the menstrual period who underwent auricular therapy. To this end, sessions were held in patients previously selected and implemented the survey of quality of life SF-36 on three different occasions. Before the first session, sixty days after the start of treatment and a third evaluation, ninety days after the beginning of treatment. The results showed that from eight individuals, seven had a general improvement in their quality of life. It follows that the treatment with auricular therapy was effective for improving quality of life of women with migraine related to menstruation. A migrânea é uma doença crônica caracterizada por crises intermitentes de cefaléia e sintomas associados, e constitui uma afecção que acomete em torno de 12 a 15 % da população em geral, em sua maioria mulheres. A qualidade de vida desses indivíduos fica comprometida, gerando um grande impacto físico, mental e social para os migranosos. Um dos métodos de tratamento que se mostra eficaz para aliviar os sintomas da migrânea menstrual é a terapia auricular ou auriculoterapia. O objetivo dessa pesquisa foi avaliar a qualidade de vida de pacientes com migrânea relacionada ao período menstrual que foram submetidos à terapia auricular. Para tanto, foram realizadas sessões de auriculoterapia em pacientes previamente selecionados e aplicado o questionário de qualidade de vida SF-36, em três momentos

    Full Text Available Aural atresia and severe microtia are associated malformations that result in problems with hearing and cosmesis, associated speech and language difficulties and diminished self-esteem. In cases where middle ear ossiculoplasty and aural atresia canalplasty are expected to give poor hearing outcomes that would eventually require the use of hearing aids, bone anchored hearing aids or active middle ear implants may be better options. This case report describes a simultaneous Vibrant Soundbridge implantation and 2nd stage auricular reconstruction with rib graft cartilage for an 11-year-old boy with grade III microtia and aural atresia 8 months after the 1st stage reconstruction. Audiometric results of the Vibrant Soundbridge aided ear were comparable to that of the contralateral hearing aid aided ear.

  10. Ultrasound-guided greater auricular nerve block as sole anesthetic for ear surgery

    Full Text Available A greater auricular nerve (GAN block was used as the sole anesthetic for facial surgery in an 80-year-old male patient with multiple comorbidities which would have made general anesthesia challenging. The GAN provides sensation to the ear, mastoid process, parotid gland, and angle of the mandible. In addition to anesthesia for operating room surgery, the GAN block can be used for outpatient or emergency department procedures without the need for a separate anesthesia team. Although this nerve block has been performed using landmark-based techniques, the ultrasoundguided version offers several potential advantages. These advantages include increased reliability of the nerve block, as well as prevention of inadvertent vascular puncture or blockade of the phrenic nerve, brachial plexus, or deep cervical plexus. The increasing access to ultrasound technology for medical care providers outside the operating room makes this ultrasound guided block an increasingly viable alternative.

    Full Text Available Durante un ultrasonido obstétrico de rutina se deben realizar ciertos planos del corazón en los cuales no es complejo identificar un grupo de anomalías como la persistencia de la vena cava superior izquierda. Cuando se identifica una vena cava superior izquierda aislada, sin otras anomalías del corazón fetal, no existe ninguna repercusión perinatal. Su importancia radica en que un grupo considerable de estos casos se acompaña de cardiopatías congénitas y anomalías anatómicas y cromosómicas. En este artículo se describen nueve casos de vena cava superior izquierda persistente, al igual que las anomalías del corazón asociadas, como también las alteraciones extracardiacas encontradas.Certain heart fetal planes must be realized during a routine obstetric ultrasound in order to identify a group of anomalies such as the persistency of the left superior caval vein. When an isolated left superior venal vein is identified without any other anomaly of the fetal heart, it does not have any perinatal repercussion. Its importance lies in the fact that a considerable number of these cases are associated with a high incidence of congenital heart diseases and anatomic and chromosomal abnormalities. This article reports nine cases of persistency of the left superior caval vein as well as the associated heart abnormalities and the extra-cardiac alterations found.

    Full Text Available Novel polyelectrolyte complex nanoparticles (AAP/LCS NPs were prepared in this study and these were produced by mixing negatively charged auricularia auricular polysaccharide (AAP with positively charged low molecular weight chitosan (LCS in an aqueous medium. The AAP was extracted and purified from auricularia auricular, and then characterized by micrOTOF-Q mass spectrometry, UV/Vis spectrophotometry, moisture analyzer and SEM. The yield, moisture, and total sugar content of the AAP were 4.5%, 6.2% and 90.12% (w/w, respectively. The AAP sample was water-soluble and exhibited white flocculence. The characteristics of AAP/LCS NPs, such as the particle size, zeta potential, morphology, FT-IR spectra, DSC were investigated. The results obtained revealed that the AAP/LCS NPs had a spherical shape with a diameter of 223 nm and a smooth surface, and the results of the FT-IR spectra and DSC investigations indicated that there was an electrostatic interaction between the two polyelectrolyte polymers. Bovine serum albumin (BSA, pI = 4.8 and bovine hemoglobin (BHb, pI = 6.8 were used as model drugs to investigate the loading and release features of the AAP/LCS NPs. The results obtained showed that the AAP/LCS NPs had a higher entrapment efficiency (92.6% for BHb than for BSA (81.5%. The cumulative release of BSA and BHb from AAP/LCS NPs after 24 h in vitro was 95.4% and 91.9%, respectively. The in vitro release demonstrated that AAP/LCS NPs provided a sustained release matrix suitable for the delivery of protein drugs. These studies demonstrate that AAP/LCS NPs have a very promising potential as a delivery system for protein drugs.

    This study aimed (1) to examine the feasibility of an auricular point acupressure (APA) research protocol in terms of recruitment and for the assessment and management of pain and (2) to examine the potential APA analgesic effects for cancer patients. This study was a repeated-measures one-group design. Participants were recruited from the cancer center follow-up clinic affiliated with a large university hospital in the northeastern United States. Participants included 50 patients aged 55-87 years with a diagnosis of cancer. Participants received 7 days of APA treatment for their pain. After appropriate acupoints were identified, vaccaria seeds were carefully taped onto each selected auricular point on each ear. The study recruitment and retention rates were 92% and 91%, respectively. Importantly, the study found preliminary evidence for the analgesic effects of APA for cancer pain management. For example, by the end of the 7-day study, APA reduced pain intensity more than 55% for "worst pain" and about 57% for "average pain" and "pain intensity." Moreover, the use of pain medication was reduced during the APA treatment (e.g., 78% of patients [n = 39] took less pain medication than before the treatment). APA appears to be highly acceptable to patients with cancer-related pain. However, without a placebo control, we cannot draw conclusive evidence for the analgesic effect of APA for cancer patients. A sham group must be added to future studies to differentiate the true effects of APA from the possible psychological effects of the APA treatment.

    Full Text Available La fibrilación auricular es la arritmia cardiaca sostenida más común y su prevalencia se duplica cada decenio por encima de los cincuenta años. Entretanto, las condiciones clínicas que más se asocian con ésta son la hipertensión arterial, la insuficiencia cardíaca, la enfermedad valvular cardíaca y la diabetes mellitus. Como complicaciones está la falla cardiaca, pero tal vez una de las peores son los eventos cardioembólicos, que ocurren aproximadamente en 4,5% de los pacientes no anticoagulados. El tratamiento antitrombótico con antagonistas de la vitamina K fue, durante más de cincuenta años, la única alternativa disponible, a pesar de sus múltiples limitaciones, las mismas que llevaron al desarrollo de nuevos fármacos anticoagulantes que disminuyen muchos de los problemas de los antagonistas de la vitamina K.

    The great auricular point (GAP) marks the exit of the great auricular nerve at the posterior border of the sternocleidomastoid muscle (SCM). It is a key landmark for the identification of the spinal accessory nerve, and its intraoperative localization is vital to avoid neurological sequelae. This study delineates the topography and surface anatomy landmarks that used to localize the GAP. Thirty cadaveric heminecks were dissected on a layer-by-layer approach. The topography of the GAP was examined relative to the insertion point of the SCM at the clavicle, tip of the mastoid process, and angle of the mandible. The GAP and its relation to the SCM were determined as a ratio of the total length of the SCM. The GAP was demonstrated to be in a predictable location. The mean length of the SCM was 131.4 ± 22 mm, and the mean distance between the GAP and the mastoid process was found to be 60.4 ± 13.76 mm. The ratio of the GAP location to the total SCM length ranged between 0.33-0.57. The mean distance between the angle of the mandible and the GAP was determined to be 57 ± 22.2 mm. Based on the midpoint of the SCM, the GAP was above it in 66.7 % of subjects and classified to Type A, and below it in 33.3 % of subjects appointed to Type B. The anatomical landmarks utilized in this study are helpful in predicting the location of the GAP relative to the midpoint of the SCM and can reduce neural injuries within the posterior triangle of the neck.

    This study aimed to isolate, culture-expand and characterize the chondrocytes isolated from microtic cartilage and evaluate its potential as a cell source for ear cartilage reconstruction. Specific attention was to construct the auricular cartilage tissue by using fibrin as scaffold. Cell culture experiment with the use of microtic chondrocytes. Cell culture experiment with the use of microtic chondrocytes. After ear reconstructive surgery at the Universiti Kebangsaan Malaysia Medical Center, chondrocytes were isolated from microtic cartilage. Chondrocytes isolated from the tissue were cultured expanded until passage 4 (P4). Upon confluency at P4, chondrocytes were harvested and tissue engineered constructs were made with human plasma polymerized to fibrin. Constructs formed later is implanted at the dorsal part of nude mice for 8 weeks, followed by post-implantation evaluation with histology staining (Hematoxylin and Eosin (H&E) and Safranin O), immunohistochemistry and RT-PCR for chondrogenic associated genes expression level. Under gross assessment, the construct after 8 weeks of implantation showed similar physical characteristics that of cartilage. Histological staining showed abundant lacunae cells embedded in extracellular matrix similar to that of native cartilage. Safranin O staining showed positive staining which indicates the presence of proteoglycan-rich matrix. Immunohistochemistry analysis showed the strong positive staining for collagen type II, the specific collagen type in the cartilage. Gene expression quantification showed no significant differences in the expression of chondrogenic gene used which is collagen type I, collagen type II, aggrecan core protein (ACP), elastin and sox9 genes when compared to construct formed from normal auricular tissue. Chondrocytes isolated from microtia cartilage has the potential to be used as an alternative cell source for external ear reconstruction in future clinical application. Copyright © 2015 Elsevier

    Aim of the study was assessment of efficacy and safety of transcutaneous stimulation of the auricular branch of the vagal nerve (t-VNS) in the treatment of chronic migraine. A monocentric, randomized, controlled, double-blind study was conducted. After one month of baseline, chronic migraine patients were randomized to receive 25 Hz or 1 Hz stimulation of the sensory vagal area at the left ear by a handhold battery driven stimulator for 4 h/day during 3 months. Headache days per 28 days were compared between baseline and the last month of treatment and the number of days with acute medication was recorded The Headache Impact Test (HIT-6) and the Migraine Disability Assessment (MIDAS) questionnaires were used to assess headache-related disability. Of 46 randomized patients, 40 finished the study (per protocol). In the per protocol analysis, patients in the 1 Hz group had a significantly larger reduction in headache days per 28 days than patients in the 25 Hz group (-7.0 ± 4.6 vs. -3.3 ± 5.4 days, p = 0.035). 29.4 % of the patients in the 1 Hz group had a ≥50 % reduction in headache days vs. 13.3 % in the 25 Hz group. HIT-6 and MIDAS scores were significantly improved in both groups, without group differences. There were no serious treatment-related adverse events. Treatment of chronic migraine by t-VNS at 1 Hz was safe and effective. The mean reduction of headache days after 12 weeks of treatment exceeded that reported for other nerve stimulating procedures.

    Full Text Available Abstract A 63-year-old man was admitted to our hospital with a complaint of right lateroabdominal pain. He was diagnosed with metastatic colon cancer, and then developed multiple brain embolic infarctions 7 days after admission. Transesophageal echocardiography showed that mobile, echo-dense masses were attached to the anterior and posterior mitral valve leaflet. Furthermore, there was a thrombus in the left auricular appendage despite sinus rhythm. These findings led to a diagnosis of suspected infectious endocarditis with subsequent multiple brain infarctions. The patient's general condition worsened and he died 13 days after admission. An autopsy was performed, and, while poorly differentiated cancer was observed in multiple organs, no primary tumor could be identified. Histological analysis showed that the masses of the mitral valve consisted mainly of fibrin without bacteria or oncocytes. This patient was therefore diagnosed with nonbacterial thrombotic endocarditis associated with cancer of unknown origin complicated with thrombus in the left auricular appendage.

    The effectiveness of bone anchored hearing aid (BAHA) for the patients with congenital aural atresia was evaluated by multicenter clinical study in Japan. Twenty patients (17 bilateral and 3 hemilateral) of congenital auricular atresia were registered for this study and finally, 18 of them (15 bilateral and 3 unilateral) were subjected to further evaluation. Primary endpoint of this study was free sound-field pure-tone audiometory and speech threshold hearing test in quiet and noisy circumstances. Secondary endpoint of this study was patient's satisfaction based upon APHAB (Abbreviated Profile of Hearing Aid Benefit) questionnaire survey. These results were compared between before and 12 weeks after BAHA surgery. Both hearing level of pure tone and speech threshold significantly improved after BAHA surgery. APHAB scores also suggested the improvement of the QOL after BAHA usage, except for the scores that concerned with unpleasantness of noisy sound. BAHA is one of the useful options for the treatment of congenital auricular atresia.

    Full Text Available La expansión de la democracia en América Latina y su extensión en el tiempo ha puesto de manifiesto una tendencia sorprendente y preocupante. Muchos de los nuevos electores latinoamericanos han dado su apoyo a candidatos de derecha y no democráticos que una vez en el poder han atentado de diversas maneras contra la democracia. Dentro del electorado se constata que ese apoyo a las fuerzas antidemocráticas es mayor en la población rural. A la luz de la bibliografía de los años 70 y 80 sobre las revoluciones campesinas de Rusia, China, Cuba o Nicaragua, este derechismo campesino es un rompecabezas: ¿los campesinos son fascistas o revolucionarios? Para descifrar este enigma, el trabajo en primer lugar analiza cuatro casos de apoyo rural al fascismo o al autoritarismo populista en la primera mitad del siglo XX (Francia, Italia, Alemania y Argentina. Compara los factores explicativos que emergen de esa comparación con los resultados obtenidos de la investigación sobre el izquierdismo campesino en China, Rusia, Cuba y Nicaragua. La conclusión del trabajo es que hay dos conjuntos de factores que explican el apoyo de los campesinos a la izquierda o a la derecha. El primer tipo de factores, de transfondo, incluye el contexto económico y las relaciones sociales de propiedad y tenencia de la tierra. El segundo tipo de factores, de primer plano,incluye el tipo de liderazgo, el estilo organizativo y la habilidad política, así como el tipo de retórica que se usa para atraer el voto campesino. La población rural no es por naturaleza ni de derecha ni de izquierda, sino que su apoyo puede llevarse a cualquiera de los dos lados dependiendo del trasfondo económico-social y de la escena política. En América Latina hay que estudiar en detalle los estilos de liderazgo y las retóricas de los candidatos. Estas variables de primera instancia nos van a permitir dictaminar si el apoyo electoral dará lugar a panoramas fascistas o autoritarios como los

    Full Text Available Objectives. To identify the efficacy of auricular acupressure on pain and disability for chronic LBP by systematic review. Methods. A search of randomized controlled trials was conducted in four English medical electronic databases and three Chinese databases. Two reviewers independently retrieved related studies, assessed the methodological quality, and extracted data with a standardized data form. Meta-analyses were performed using all time-points meta-analysis. Results. A total of 7 trials met the inclusion criteria, of which 4 had the low risk of bias. The findings of this study showed that, for the immediate effect, auricular acupressure had large, significant effects in improving pain within 12 weeks. As for the follow-up effect, the pooled estimates also showed promising effect at 4-week follow-up after 4-week intervention (standardized mean difference = −1.13, 95% CI (-1.70, -0.56, P<0.001. But, for the disability level, the therapeutic effect was not significant (mean difference = −1.99, 95% CI (-4.93, 0.95, P=0.18. No serious adverse effects were recorded. Conclusions. The encouraging evidence of this study indicates that it is recommended to provide auricular acupressure to patients with chronic low back pain. However, a more accurate estimate of the effect will require further rigorously designed large-scale RCTs on chronic LBP for improving pain and disability.

    Full Text Available Reconstruction of the human auricle remains a challenge to plastic surgeons, and current approaches are not ideal. Tissue engineering provides a promising alternative. This study aims to evaluate the chondrogenic potential of bone marrow–derived mesenchymal stem cells on a novel, auricular-shaped polymer. The proposed polyhedral oligomeric silsesquioxane-modified poly(hexanolactone/carbonateurethane/urea nanocomposite polymer has already been transplanted in patients as the world’s first synthetic trachea, tear duct and vascular bypass graft. The nanocomposite scaffold was fabricated via a coagulation/salt-leaching method and shaped into an auricle. Adult bone marrow–derived mesenchymal stem cells were isolated, cultured and seeded onto the scaffold. On day 21, samples were sent for scanning electron microscopy, histology and immunofluorescence to assess for neocartilage formation. Cell viability assay confirmed cytocompatability and normal patterns of cellular growth at 7, 14 and 21 days after culture. This study demonstrates the potential of a novel polyhedral oligomeric silsesquioxane-modified poly(hexanolactone/carbonateurethane/urea scaffold for culturing bone marrow–derived mesenchymal stem cells in chondrogenic medium to produce an auricular-shaped construct. This is supported by scanning electron microscopy, histological and immunofluorescence analysis revealing markers of chondrogenesis including collagen type II, SOX-9, glycosaminoglycan and elastin. To the best of our knowledge, this is the first report of stem cell application on an auricular-shaped scaffold for tissue engineering purposes. Although many obstacles remain in producing a functional auricle, this is a promising step forward.

    Full Text Available La fibrilación auricular es el trastorno del ritmo cardíaco más frecuente. Durante años, su tratamiento se vio limitado casi exclusivamente al control farmacológico de la frecuencia cardíaca y a la prevención de eventos tromboembólicos con fármacos anticoagulantes. Debido a los recientes avances en el campo de la electrofisiología cardíaca y al desarrollo tecnológico, el abordaje terapéutico de esta arritmia se contempla hoy en día desde una perspectiva mucho más intervencionista que antaño. Recientemente, técnicas de cirugía videoasistida de última generación han comenzado a ser aplicadas en el tratamiento de la fibrilación auricular aislada con dos modalidades de abordaje: la cirugía mediante miniincisiones (minitoracotomía y la cirugía toracoscópica propiamente dicha. En este artículo describiremos y comentaremos estas formas de tratamiento quirúrgico de la fibrilación auricular.

    To examine the effects of auricular acupressure with Sinapsis alba seeds on obesity and self-efficacy. Randomized controlled trial. College settings located in metropolitan areas of Korea. A total of 49 female college students who were overweight or obese (body-mass index [BMI] ≥25.0 kg/m(2)) were recruited and randomly assigned to the experimental group (n=25) or the control group (n=24). The experimental group applied three S. alba seeds to each of five auricular points (Shenmen, mouth, stomach, endocrine, and small intestine points). These participants were asked to stimulate those points 10 times at a rate of two times per second 30 minutes before mealtime, three times daily, for 1 month. They performed the procedure for each earlobe for alternating weeks (a total of 2 weeks' treatment for each ear). The obesity index included weight (kg), BMI (kg/m(2)), percentage body fat, and waist-to-hip ratio. Self-efficacy was measured by using a self-efficacy scale. Female students in the experimental group showed significant decreases in weight (t=10.76; p0.05) and waist-to-hip ratio (t=0.60; p>0.05) changes did not significantly differ between the two groups. These findings suggest that auricular acupressure using S. alba seeds may be an effective intervention for decreasing weight and BMI and increasing self-efficacy of overweight and obese individuals.

    Previous vagus nerve stimulation (VNS) studies have demonstrated antinociceptive effects, and recent noninvasive approaches, termed transcutaneous-vagus nerve stimulation (t-VNS), have utilized stimulation of the auricular branch of the vagus nerve in the ear. The dorsal medullary vagal system operates in tune with respiration, and we propose that supplying vagal afferent stimulation gated to the exhalation phase of respiration can optimize t-VNS. Counterbalanced, crossover study. Patients with chronic pelvic pain (CPP) due to endometriosis in a specialty pain clinic. INTERVENTIONS/OUTCOMES: We evaluated evoked pain analgesia for respiratory-gated auricular vagal afferent nerve stimulation (RAVANS) compared with nonvagal auricular stimulation (NVAS). RAVANS and NVAS were evaluated in separate sessions spaced at least 1 week apart. Outcome measures included deep-tissue pain intensity, temporal summation of pain, and anxiety ratings, which were assessed at baseline, during active stimulation, immediately following stimulation, and 15 minutes after stimulus cessation. RAVANS demonstrated a trend for reduced evoked pain intensity and temporal summation of mechanical pain, and significantly reduced anxiety in N = 15 CPP patients, compared with NVAS, with moderate to large effect sizes (η(2) > 0.2). Chronic pain disorders such as CPP are in great need of effective, nonpharmacological options for treatment. RAVANS produced promising antinociceptive effects for quantitative sensory testing (QST) outcomes reflective of the noted hyperalgesia and central sensitization in this patient population. Future studies should evaluate longer-term application of RAVANS to examine its effects on both QST outcomes and clinical pain. Wiley Periodicals, Inc.

    Full Text Available Background. Dysmenorrhea and accompanying symptoms can have a negative impact on academic achievement, physical activity and functioning, and quality of life. Unfortunately, stress increases the sensitivity and severity of pain, activating sympathetic responses while inhibiting parasympathetic responses. Objective. This study used objective, physiological measurements to evaluate the effects of auricular acupressure on menstrual pain and menstrual distress in young college students with primary dysmenorrhea across two menstrual cycles. The aim was to determine if significant differences could be detected between the intervention and follow-up phases after controlling life stress. Design. A one-group experimental research design was used, and repeated measurements and followups were done. Thirty-two women completed questionnaires and physiological parameters were measured. Results. Significant differences between the intervention and follow-up phases were found for high frequency (HF and blood pressure on day 1 and no significant differences in menstrual pain and menstrual distress, heart rate variability, low frequency (LF, LF/HF ratio, or heart rate. Conclusion. Auricular acupressure effectively increases parasympathetic activity to maintain autonomic function homeostasis in young women with primary dysmenorrhea and may have a value in alleviating menstrual pain and menstrual distress in a high-stress life. Future studies should consider stress, stimulus dose of auricular acupressure, severity of menstrual pain, and a longitudinal research design.

    Prevalence of left appendage thrombosis ranges from 6 to 18% in persistent atrial fibrillation (AF). Few and low sample size studies have assessed left and right atrial thrombosis in persistent atrial flutter (AFL) and a wide variety of frequencies, from 1 to 21%, has been reported. The aim of this study was to evaluate the prevalence of atrial appendage thrombosis in a large population of patients undergoing transoesophageal echocardiography (TEE)-guided cardioversion (CV) for recent AFL onset and compare it with AF. From 1999 to September 2014, we collected data of 1081 patients to CV: 877 affected by AF (81.1%) and 204 by AFL (18.9%). The presence of auricular thrombosis was evaluated by TEE in AF or AFL persisting for more than 48 h. The presence of appendage thrombosis, Doppler emptying velocities, and severe spontaneous echo contrast (SEC) was studied. The overall prevalence of atrial thrombosis was 9.62% (104/1081). Frequency of atrial thrombosis in AFL patients was 6.4% (13/204) vs. 10.5% among AF (92/877), P = 0.074. Comparing the two appendages, frequency of left atrial appendage thrombosis was in AFL 5.9% (12/204) vs. 9.9% (87/877) in the AF group, P = 0.07. Right atrial appendage thrombosis was present in 0.5% (1/204) in the AFL group vs. 0.8% (7/877) in the AF group, P = 0.64. Moderate to severe SEC (3+/4+) was present in 28% of AFL patients (57/204) vs. 35% of AF patients (307/877), P = 0.05. Auricular thrombosis is not an infrequent finding in AFL before CV. Our study suggests the use of TEE screening in AFL, as well as in AF, when patients arrive to clinical attention after more than 48 h from arrhythmia onset.

    Malignant tumour in upper lid is a surgical challenge to oculoplastic surgeon. Full thickness defect created after removal of large tumour promptly treated with modified cutler beard procedure using autogenous auricular cartilage. Surgical procedure is two staged: In first stage, removal of the tumour followed by full thickness flap repaired; In second stage, opening the closed lid with lid margin repair. Post-operatively, there is good anatomical, functional and cosmetic restoration of the eyelid similar to the other eye. To evaluate the efficacy of the modified Cutler-Beard procedure using autogenous ear cartilage for tarsal plate reconstruction in the repair of 70-100% upper eyelid defects. This is a prospective, interventional case series of 16 patients over a period of three years. Patients with upper eyelid defects, secondary to removal of tumour, greater than or equal to 70% were included. Of these patients, those with lymph node involvement, distant metastasis, lower eyelid involvement, corneal infiltration or intra-orbital extension were excluded. FNAC was done in all the cases. Created defect was measured in mm (length and width) and later expressed in percentage. Pre and Post-operative measurement of Levator Palpebrae Superioris (LPS) was done. Pre and Post-operative measurement of Margin to Reflex Distance (MRD1) were also noted. Upper eyelid recreation was successful in all patients without complications. Pre-operative LPS action ranged from 0-4 mm, while post-operative LPS action was 12-14 mm. Pre-operative MRD1 ranged from -4 millimeters to -1 mm, while post-operative MRD1 was +3 to +4 millimeters. The follow-up period ranged from six months to two years. Every patient had a successful upper eyelid reconstruction. The modified Cutler-Beard procedure using an autogenous auricular cartilage graft is an effective procedure for repair of large upper eyelid defects, with acceptable functional and cosmetic results. Furthermore, it is particularly useful in

    The use of computer-aided design/computer-aided manufacturing (CAD/CAM) and additive manufacturing in maxillofacial prosthetics has been widely acknowledged. Rapid prototyping can be considered for manufacturing of auricular prostheses. Therefore, so-called prostheses replicas can be fabricated by digital means. The objective of this study was to identify a superior additive manufacturing method to fabricate auricular prosthesis replicas (APRs) within a digital workflow. Auricles of 23 healthy subjects (mean age of 37.8 years) were measured in vivo with respect to an anthropometrical protocol. Landmarks were volumized with fiducial balls for 3D scanning using a handheld structured light scanner. The 3D CAD dataset was postprocessed, and the same anthropometrical measurements were made in the CAD software with the digital lineal. Each CAD dataset was materialized using fused deposition modeling (FDM), selective laser sintering (SLS), and stereolithography (SL), constituting 53 APR samples. All distances between the landmarks were measured on the APRs. After the determination of the measurement error within the five data groups (in vivo, CAD, FDM, SLS, and SL), the mean values were compared using matched pairs method. To this, the in vivo and CAD dataset were set as references. Finally, the surface structure of the APRs was qualitatively evaluated with stereomicroscopy and profilometry to ascertain the level of skin detail reproduction. The anthropometrical approach showed drawbacks in measuring the protrusion of the ear's helix. The measurement error within all groups of measurements was calculated between 0.20 and 0.28 mm, implying a high reproducibility. The lowest mean differences of 53 produced APRs were found in FDM (0.43%) followed by SLS (0.54%) and SL (0.59%)--compared to in vivo, and again in FDM (0.20%) followed by SL (0.36%) and SLS (0.39%)--compared to CAD. None of these values exceed the threshold of clinical relevance (1.5%); however, the qualitative

    Auricular prostheses for defects of external ear are retained either by mechanical means or implants. All implant retained prostheses are retained by various means such as bar and clip, magnetic attachments or a combination of bar, clip and magnets. The commonest problem encountered with the bar and clip system is loosening of the clip after 3-4 months. When magnets are used as retaining component they tend to corrode over a period of time. So various alternative retention methods which possess good retentive qualities, ease of reparability and patient friendly were tried. In the present case a newly modified Hader bar design which can act as an additional retentive feature apart from the clip is employed to increase retention. The major advantages in the modified Hader bar system were that only two implants were employed, the additional loops in the Hader bar prevented micro movements and the retentive acrylic locks were easy to repair if broken. The modified Hader bar has anti-rotational slots which prevents the sliding or rotation of the prosthesis which gave new confidence to the patient who was otherwise worried of inadvertent displacement of the ear prosthesis while playing.

    Ear reconstruction remains a challenge for plastic surgeons. A tissue-engineering approach could provide another route for obtaining shape maintenance in neoauricular tissue. The authors designed a novel tissue-engineering auricular construct by culturing human adipose stem cells, which differentiated into osteocytes but not chondrocytes, in small intestine submucosa scaffolds. The authors evaluated cell growth potential and mechanical properties. An ear-shaped construct was created in vitro and then implanted in the backs of nude mice. The histology, cellularity, neovascularization, mechanical properties, and ear shape maintenance were investigated. In vitro, human adipose stem cells could be successfully seeded in the small intestine submucosa and differentiated toward osteogenesis. The ear-shaped human adipose stem cell/small intestine submucosa construct could maintain its shape in vivo up to 1 year. Alizarin Red S staining confirmed osteogenic differentiation. CD31 stain showed prominent angiogenesis in the human adipose stem cell/small intestine submucosa construct at 6 months and persistence up to 1 year. h-MHC stain revealed the maintenance of cellularity at 6 months and persistence up to 1 year. The mechanical properties were similar to those of native ear cartilage. The authors' study found that the combination of human adipose stem cells and small intestine submucosa could provide a more durable ear-shaped construct in vivo. The mechanical properties, shape, and cellularity were maintained in the constructs for up to 12 months. Therapeutic, V.

    Microtia is a major congenital anomaly of the external ear. It includes a spectrum of deformities from a grossly normal but small ear to the absence of the entire external ear. These deformities account for three in every 10,000 births, with bilaterally missing ears seen in fewer than 10% of all cases. Congenital abnormalities of the ear are unlikely to result in the complete absence of the ears, but the patient presented in this article had bilateral congenitally missing ears. There was loss of anatomic landmarks and alteration of normal bony architecture. Minimal tissue was available for retention; therefore, conventional techniques could not be used for achieving retention. A two-implant-supported auricular prosthesis was planned, but the patient was found to have deficient bone in the implant site. Hence the implants were placed posterior to these sites, and the superstructure was modified to accommodate for this change in position of the implant to ensure the esthetic positioning of the prosthesis. © 2012 by the American College of Prosthodontists.

    Full Text Available Development of wearable point-of-care medical devices faces many challenges. Besides technological and clinical issues, demands on robustness, miniaturization, and user interface design are of paramount importance. However, a systematic assessment of these non-functional but essential requirements is often impossible within the first product cycle. Later, surveys on user satisfaction with existing devices and user demands can offer significant input for device re-development and improvement. In this paper, we present a survey on satisfaction with and demands for a wearable medical device for percutaneous auricular vagus nerve stimulation (pVNS. We analyzed 36 responses from patients treated with pVNS and five responses from experienced physicians in order to devise a future concept of pVNS. Main shortcomings of a current pVNS device were identified to be lacking water resistance and mechanical robustness, both impairing daily activities. Painful sensation during pVNS application, unwanted side effects like skin irritations and strongly varying perception of the stimulation were reported. Results urge for more patient self-governance and an (automatic adjustment of the stimulation to the current physiological state of the patient. Attained results support a strategic approach for future developments of pVNS towards personalized health care.

    Severe burns in children are conventionally treated with split-thickness skin autografts or epidermal sheets. An alternative approach is to graft isolated keratinocytes. We evaluated foreskin and other anatomic sites as donor sources for autologous keratinocyte graft in children. We studied in vitro capacities of isolated keratinocytes to divide and reconstitute epidermal tissue. Keratinocytes were isolated from foreskin, auricular skin, chest and abdominal skin by enzymatic digestion. Living cell recovery, in vitro proliferation, epidermal reconstruction capacities and differentiation status were analyzed. In vitro studies revealed the higher yield of living keratinocyte recovery from foreskin and higher potential in terms of proliferative capacity, regeneration and differentiation. Cultured keratinocytes from foreskin express lower amounts of differentiation markers than those isolated from trunk and ear. Histological analysis of reconstituted human epidermis derived from foreskin and inguinal keratinocytes showed a structured multilayered epithelium, whereas those obtained from ear pinna-derived keratinocytes were unstructured. Our studies highlight the potential of foreskin tissue for autograft applications in boys. A suitable alternative donor site for autologous cell transplantation in female paediatric burn patients remains an open question in our department. We tested the hypothesis that in vitro studies and RHE reconstructive capacities of cells from different body sites can be helpful to select an optimal site for keratinocyte isolation before considering graft protocols for girls.

    Xerostomia is one of the most common complaints in maintenance hemodialysis (MHD) patients. This problem contributes to excess fluid intake and results in poor survival outcome. Based on Traditional Chinese Medicine (TCM) theory and literature studies, the authors have been practicing auricular acupressure therapy (AAT) to help patients with xerostomia. This pilot study was conducted to demonstrate the potential of AAT for xerostomia in MHD patients. Eligible subjects who agreed to participate in this study were recruited and provided with AAT for 4 weeks. The Summated Xerostomia Inventory (SXI), as well as measurement of inter-dialytic weight gain (IDWG), daily inter-dialytic weight gain (daily IDWG), percentage of inter-dialytic weight gain (IDWG%), blood pressure, and biochemical parameters, were completed at baseline and after a 4-week intervention. A total of 26 eligible participants were recruited. Of them, 10 men and 16 women (M age  = 52.92 ± 11.80 years; dialysis vintage 81.86 ± 46.05 months) completed the study. After the 4-week AAT intervention, the SXI scores were significantly decreased compared with baseline (from 10.08 ± 2.26 to 9.04 ± 2.14; p xerostomia intensity for MHD patients.

    Previous studies demonstrated that vagus nerve stimulation (VNS) is an effective therapy for drug-resistant epilepsy. Acupuncture is also used to treat epilepsy. This study was designed to examine the safety and effectiveness of transcutaneous auricular vagus nerve stimulation (ta-VNS) for patients with drug-resistant epilepsy. A total of 50 volunteer patients with drug-resistant epilepsy were selected for a random clinical trial to observe the therapeutic effect of ta-VNS. The seizure frequency, quality of life, and severity were assessed in weeks 8, 16, and 24 of the treatment according to the percentage of seizure frequency reduction. In the pilot study, 47 of the 50 epilepsy patients completed the 24-week treatment; three dropped off. After 8-week treatment, six of the 47 patients (12%) were seizure free and 12 (24%) had a reduction in seizure frequency. In week 16 of the continuous treatment, six of the 47 patients (12%) were seizure free; 17 (34%) had a reduction in seizure frequency. After 24 weeks' treatment, eight patients (16%) were seizure free; 19 (38%) had reduced seizure frequency. Similar to the therapeutic effect of VNS, ta-VNS can suppress epileptic seizures and is a safe, effective, economical, and widely applicable treatment option for drug-resistant epilepsy.

    Full Text Available El tratamiento quirúrgico de la fibrilación auricular fue introducido por Cox en 1987. Se trata de un procedimiento muy eficaz, pero su uso no se ha extendido por su dificultad técnica y su mayor morbimortalidad en manos poco expertas. En los últimos años se han desarrollado dispositivos capaces de sustituir las múltiples incisiones y suturas de la intervención por líneas de ablación realizadas con diferentes fuentes de energía, haciéndola más sencilla y rápida. Aunque los resultados a corto y medio plazo son buenos, todavía quedan bastantes aspectos por definir: mecanismos de la arritmia, patrón de lesiones más apropiado, fuente de energía más segura y eficaz y manera de comunicar los resultados, entre otros.

    Full Text Available The objective of this study is to explore the effects of acupuncture and auricular acupressure in relieving menopausal hot flashes of bilaterally ovariectomized Chinese women. Between May 2006 and March 2008, 46 bilaterally ovariectomized Chinese women were randomized into an acupuncture and auricular acupressure group (n = 21 and a hormone replacement therapy (HRT group (Tibolone, n = 25. Each patient was given a standard daily log and was required to record the frequency and severity of hot flashes and side effects of the treatment felt daily, from 1 week before the treatment started to the fourth week after the treatment ended. The serum levels of follicle stimulating hormone (FSH, LH and E2 were detected before and after the treatment. After the treatment and the follow-up, both the severity and frequency of hot flashes in the two groups were relieved significantly when compared with pre-treatment (P   .05, while after the follow-up, the severity of hot flashes in the HRT group was alleviated more. After the treatment and the follow-up, the frequency of menopausal hot flashes in the HRT group was reduced more (P <  .05. After treatment, the levels of FSH decreased significantly and the levels of E2 increased significantly in both groups (P <  .05, and they changed more in the HRT group (P <  .05. Acupuncture and auricular acupressure can be used as alternative treatments to relieve menopausal hot flashes for those bilaterally ovariectomized women who are unable or unwilling to receive HRT.

    OBJECTIVE To determine the pharmacokinetics of florfenicol, terbinafine, and betamethasone acetate after topical application to canine auricular skin and the influence of synthetic canine cerumen on pharmacokinetics. SAMPLE Auricular skin from 6 euthanized shelter dogs (3 females and 3 neutered males with no visible signs of otitis externa). PROCEDURES Skin adjacent to the external opening of the ear canal was collected and prepared for use in a 2-compartment flow-through diffusion cell system to evaluate penetration of an otic gel containing florfenicol, terbinafine, and betamethasone acetate over a 24-hour period. Radiolabeled 14 C-terbinafine hydrochloride and 3 H-betamethasone acetate were added to the gel to determine dermal penetration and distribution. Florfenicol absorption was determined by use of high-performance liquid chromatography-UV detection. Additionally, the effect of synthetic canine cerumen on the pharmacokinetics of all compounds was evaluated. RESULTS During the 24-hour experiment, mean ± SD percentage absorption without the presence of synthetic canine cerumen was 0.28 ± 0.09% for 3H-betamethasone acetate, 0.06 ± 0.06% for florfenicol, and 0.06 ± 0.02% for 14C-terbinafine hydrochloride. Absorption profiles revealed no impact of synthetic canine cerumen on skin absorption for all 3 active compounds in the gel or on skin distribution of 3 H-betamethasone acetate and 14 C-terbinafine hydrochloride. CONCLUSIONS AND CLINICAL RELEVANCE 3 H-betamethasone acetate, 14 C-terbinafine hydrochloride, and florfenicol were all absorbed in vitro through healthy auricular skin specimens within the first 24 hours after topical application. Synthetic canine cerumen had no impact on dermal absorption in vitro, but it may serve as a temporary reservoir that prolongs the release of topical drugs.

    To compare the therapeutic differences among scalp acupuncture combined with auricular point sticking, body acupuncture and western medication for treatment of vascular dementia (VD). Ninety cases were randomly divided into a combined therapy group (31 cases), a body acupuncture group (29 cases) and a western medication group (30 cases). The combined therapy group was treated with scalp acupuncture at forehead middle line, parieral middle line, temporal front line and temporal rear line as well as auricular point sticking at naogan (AT3,41), shen (CO10), shenmen (TF4), zhen (AT3), once a day; the body acupuncture group was treated with acupuncture at Baihui (GV 20), Fengchi (GB 20), Zusanli (ST 36) and so on, once a day; the western medication group was treated with oral administration of aniracetam tablets, 0.2 g per time, twice a day. Fourteen days were considered as a treatment course, and totally 3 courses were required. The mini-mental state examination (MMSE) and activities of daily living (ADL) were applied to assess the changes of cognitive behavior ability before and after treatment among three groups. Also the efficacy among three groups were compared. One case dropped out in the body acupuncture group and western medication group, respectively. The total effective rate was 90.334 (28/31) in the combined therapy group, which was superior to 85.734 (24/28) in the body acupuncture group and 79.3% (23/29) in the western medication group (both P acupuncture combined with auricular point sticking could improve the clinical symptoms and cognitive behavior ability in patients with vascular dementia, which has superior total efficacy to body acupuncture and western medication aniracetam tablets.

    The concept of prosthesis-guided implantation has been widely accepted for intraoral implant placement, although clinicians do not fully appreciate its use for facial defect restoration. In this clinical report, multiple digital technologies were used to restore a facial defect with prosthesis-guided implantation. A simulation surgery was performed to remove the residual auricular tissue and to ensure the correct position of the mirrored contralateral ear model. The combined application of computed tomography and 3-dimensional photography preserved the position of the mirrored model and facilitated the definitive implant-retained auricular prosthesis.

    Auricular acupuncture (AA) is effective for the treatment of preoperative anxiety. We aimed to study the feasibility and effects of AA on exam anxiety in a prospective observational pilot study. Healthy medical students received bilateral AA using indwelling fixed needles at points MA-IC1, MA-TF1, MA-SC, MA-AH7, and MA-T on the day before an anatomy exam. The needles were removed after the exam. Anxiety levels were measured using the State-Trait-Anxiety Inventory (STAI) and a 100 mm visual analogue scale (VAS-100) before and after the AA intervention and once again immediately before the exam. The duration of sleep on the night before the exam was recorded and compared to that over the preceding 1 week and 6 months (all through students' recollection). In addition, blood pressure, heart rate and the acceptability of AA to the students were recorded. Ten students (all female) were included in the final analysis. All tolerated the needles well and stated they would wish to receive AA again for exam anxiety in the future. Exam anxiety measured using both STAI and VAS-100 decreased by almost 20% after AA. AA was well accepted, the outcome measurement was feasible, and the results have facilitated the calculation of the sample size for a subsequent randomised controlled trial.

    Cutaneous papillary squamous cell carcinomas (SCCs) are extremely rare in humans and have not been reported in any nonhuman species. In humans, oral papillary SCCs are often caused by papillomavirus infection and have a more favourable prognosis than other SCC subtypes. A 10-year-old ginger and white domestic short hair cat had a 12 month history of symmetrical, roughly circular, exophytic 2 cm diameter masses in both pre-auricular regions. Surgical excision was performed, although with only narrow margins. Histology of both masses revealed a proliferation of neoplastic keratinocytes arranged in numerous filiform projections that were supported by fibrovascular stalks. Although the cells were confined to the epidermis predominantly, nests of neoplastic cells were visible within the superficial dermis. The neoplastic cells demonstrated significant atypia with a variable nuclear:cytoplasmic ratio and a high mitotic index. A papillary subtype SCC was diagnosed. Felis catus papillomavirus type 2 (FcaPV-2) was the only papillomavirus detected in the masses and FcaPV-2 E6/E7 gene expression and p16 CDKN 2A protein immunostaining were detected. Six months after surgery neither recurrence nor further masses had developed. This is the first cutaneous papillary SCC reported in a nonhuman species. Papillary SCCs may be a rare manifestation of FcaPV-2 infection in cats. The unusual location of the SCCs suggests that both papillomavirus infection and ultraviolet light exposure could have contributed to neoplasia development. Evidence from this single case suggests that papillary SCCs may have a more favourable prognosis than conventional SCCs in cats. © 2016 ESVD and ACVD.

  4. Treating Depression with Transcutaneous Auricular Vagus Nerve Stimulation: State of the Art and Future Perspectives

    Full Text Available Depression is a highly prevalent disorder, and its treatment is far from satisfactory. There is an urgent need to develop a new treatment for depression. Although still at its early stage, transcutaneous auricular vagus nerve stimulation (taVNS has shown promising potential for treating depression. In this article, we first summarize the results of clinical studies on the treatment effect of taVNS on depression. Then, we re-analyze a previous study to identify the specific symptoms taVNS can relieve as indicated by subscores of the 24-item Hamilton Depression Scale in patients with depression. We found that taVNS can significantly reduce multiple symptoms of depression patients, including anxiety, psychomotor retardation, sleep disturbance, and hopelessness. Next, we pose several hypotheses on the mechanism of taVNS treatment of depression, including directly and indirectly modulating the activity and connectivity of key brain regions involved in depression and mood regulation; inhibiting neuro-inflammatory sensitization; modulating hippocampal neurogenesis; and regulating the microbiome–brain–gut axis. Finally, we outline current challenges and lay out the future directions of taVNS treatment of depression, which include (1 intensively comparing stimulation parameters and “dose effect” (treatment frequency and duration to maximize the treatment effect of taVNS; (2 exploring the effect of taVNS on disorders comorbid with depression (such as chronic pain disorders, cardiovascular disorder, and autism to provide new “two-for-one” treatment approaches for patients with these disorders; and (3 applying multiple scale methods to explore the underlying mechanism of taVNS.

    Full Text Available Objective. The most effective nonpharmacological treatment for insomnia disorder is cognitive behavioural therapy-insomnia (CBT-i. However CBT-i may not suit everyone. Auricular acupuncture (AA is a complementary treatment. Studies show that it may alleviate insomnia symptoms. The aim of this randomised controlled study was to compare treatment effects of AA with CBT-i and evaluate symptoms of insomnia severity, anxiety, and depression. Method. Fifty-nine participants, mean age 60.5 years (SD 9.4, with insomnia disorder were randomised to group treatment with AA or CBT-i. Self-report questionnaires, the Insomnia Severity Index (ISI, Dysfunctional Beliefs and Attitudes about Sleep scale (DBAS-16, Epworth Sleepiness Scale (ESS, and Hospital Anxiety and Depression scale (HAD, were collected at baseline, after treatment, and at 6-month follow-up. A series of linear mixed models were performed to examine treatment effect over time between and within the groups. Results. Significant between-group improvements were seen in favour of CBT-i in ISI after treatment and at the 6-month follow-up and in DBAS-16 after treatment. Both groups showed significant within-group postintervention improvements in ISI, and these changes were maintained six months later. The CBT-i group also showed a significant reduction in DBAS-16 after treatment and six months later. Conclusions. Compared to CBT-i, AA, as offered in this study, cannot be considered an effective stand-alone treatment for insomnia disorder. The trial is registered with ClinicalTrials.gov NCT01765959.

    In several countries the most common cause of death in young people is cancer. Patients with head and neck cancer often have complications after cancer treatment. Radiation therapy can cause oral trismus, which is related to high doses of radiation. Although acupuncture is reported to be effective and is widely used for the treatment of peripheral facial paralysis by promoting an improvement of motor functions, few reports in the literature demonstrate its effectiveness. We report a case in which the symptoms of a patient with facial paralysis after surgical cancer treatment associated with chemotherapy and radiotherapy improved after laser treatment at acupuncture points. Ten weekly sessions of laser therapy were conducted, using the Twin laser device, applied to systemic acupuncture points (LR3, LI4, LI18, LI19, LI20, SI17, SI19, ST4, ST6, ST7, GV20), together with 10 weekly sessions of auricular acupressure. Significant improvement of the trismus was seen, confirmed by the increase in mouth opening from 33.26 to 53.3 mm. The patient's family also noted reduced anxiety and hyperactivity. These results suggest that laser acupuncture and auricular acupressure for trismus and facial paralysis following cancer treatment is worth further investigation.

    We report an interesting case of a right temporal pre-auricular arteriovenous fistula (cirsoid aneurysm) causing intractable tinnitus successfully managed by transarterial n-butyl cyanoacrylate glue embolisation. A 52-year-old female presented with a one-year history of tinnitus and pulsatile swelling in the right pre-auricular region. A colour Doppler ultrasound test and magnetic resonance angiography revealed a high-flow scalp arteriovenous fistula with a feeder vessel from the distal superficial temporal artery, which drained into the corresponding, dilated, tortuous vein. The patient underwent diagnostic digital subtraction angiography. This was followed by transarterial embolisation of the fistula using a 50 per cent mixture of n-butyl cyanoacrylate glue and Lipiodol®, with manual distal venous occlusion. A successful outcome was achieved with instant relief of symptoms. Cirsoid aneurysms of the facial region, an uncommon cause of tinnitus, can be effectively managed by endovascular embolisation. This treatment obviates the need for surgery, which is associated with an increased risk of complications such as scarring, deformity and bleeding.

    Implant-retained auricular prostheses are a successful treatment modality for children with microtia. They involve only minor surgical intervention of implant placement and result in an esthetically pleasing outcome. Integration of digital technologies (DT) in the prosthetic reconstruction process is a new approach toward enhancing outcomes. In this report we present a case of auricular prosthetic reconstruction following two implant placements in the right mastoid region. The ear prosthesis was constructed with the aid of various DTs. A structured light laser scanner was used to digitize the nondefect patient ear. The digitized 3D ear was then manipulated in specialist software, mirrored to reflect the opposing side, and a Rapid Prototyping (RP) machine (Z-Corp) was used to manufacture the soft tissue required. This RP-mirrored ear model allows very accurate reproduction to replicate missing soft tissue. A color Spectrometer was used to accurately reproduce skin tones. The use of these technologies is now routine practice at our unit. They enhance prosthetic outcomes and esthetics, save the prosthetist's time, and are digitally stored and subsequently readily available and reproducible. © 2012 by the American College of Prosthodontists.

    Why regeneration does not occur in mammals remains elusive. In lower vertebrates, epimorphic regeneration of the limb is directed by the wound epidermis, which controls blastema formation to promote regrowth of the appendage. Herein, we report that knockout (KO) or inhibition of Apoptosis Signal-regulated Kinase-1 (ASK1), also known as mitogen-activated protein kinase kinase kinase 5 (MAP3K5), after full thickness ear punch in mice prolongs keratinocyte activation within the wound epidermis and promotes regeneration of auricular cartilage. Histological analysis showed the ASK1 KO ears displayed enhanced protein markers associated with blastema formation, hole closure and regeneration of auricular cartilage. At seven days after punch, the wound epidermis morphology was markedly different in the KO, showing a thickened stratum corneum with rounded cell morphology and a reduction of both the granular cell layer and decreased expression of filament aggregating protein. In addition, cytokeratin 6 was expressed in the stratum spinosum and granulosum. Topical application of inhibitors of ASK1 (NQDI-1), the upstream ASK1 activator, calcium activated mitogen kinase 2 (KN93), or the downstream target, c-Jun N-terminal kinase (SP600125) also resulted in enhanced regeneration; whereas inhibition of the other downstream target, the p38 α/β isoforms, (SB203580) had no effect. The results of this investigation indicate ASK1 inhibition prolongs keratinocyte and blastemal cell activation leading to ear regeneration.

    To observe the inhibitory effect of auricular concha transcutaneous electrostimulation (ACTES) of different frequencies and duration on acute seizures in epilepsy rats so as to select a better stimulating parameter for relieving epilepsy. According to the stimulation duration of ACTES, 44 Sprague-Dawley rats were randomized into: 30 s, 5 min, 10 min, and 30 min groups. Epilepsy model was duplicated by intraperitoneal injection of PTZ (pentylenetetrazol, 50 mg/kg). Cerebral field potentials delivered from the fixed 4 recording electrodes array (A-P: -3 -6, L: 4 - 6, H: 1. 5) and reference electrode (a fixed screw) touching the cerebral dura surface were recorded using a data acquisition system (Cerebus 5.0 system). Transcutaneous electrostimulation (1 mA, duration 500 micro(s)) of frequency 2 Hz, 20 Hz and 100 Hz was applied to auricular concha by using an electric stimulator. The anti-epileptic effects of ACTES were evaluated by using the duration and rate of seizure suppression. (1) The anti-epileptic effect of 20 Hz -ACTES was markedly longer than those of 2 Hz and 100 Hz in the duration of seizure suppression (P epilepsy rats.

    Full Text Available Background. Postoperative pain management remains a significant challenge for all healthcare providers. A randomized controlled trial was conducted to examine the adjuvant effects of auricular acupressure on relieving postoperative pain and improving the passive range of motion in patients with total knee replacement (TKR. Method. Sixty-two patients who had undergone a TKR were randomly assigned to the acupressure group and the sham control group. The intervention was delivered three times a day for 3 days. A visual analog scale (VAS and the Short-Form McGill Pain Questionnaire were used to assess pain intensity. Pain medication consumption was recorded, and the knee motion was measured using a goniometer. Results. The patients experienced a moderately severe level of pain postoperatively (VAS 58.66 ± 20.35 while being on the routine PCA. No differences were found in pain scores between the groups at all points. However, analgesic drug usage in the acupressure group patients was significantly lower than in the sham control group (<0.05, controlling for BMI, age, and pain score. On the 3rd day after surgery, the passive knee motion in the acupressure group patients was significantly better than in the sham control group patients (<0.05, controlling for BMI. Conclusion. The application of auricular acupressure at specific therapeutic points significantly reduces the opioid analgesia requirement and improves the knee motion in patients with TKR.

    Full Text Available Objective. To identify the optimum treatment protocol for insomnia among auricular, body, and abdominal needling methods. Methods. A three-factor (3 needling protocols and three-level experimental scheme was designed based on orthogonal method. 54 patients of insomnia differentiated as internal harassment of phlegm-heat syndrome were given two courses of acupuncture treatment (each with 20 times of acupuncture. The therapeutic effects were evaluated by comparing the Pittsburgh sleep quality index (PSQI, Hamilton Depression Scale (HAMD scores, and Hamilton Anxiety Scale (HAMA scores of patients before treatment, after one course of treatment, and after two courses of treatment as well as one month after treatment. Results. Body, auricular, and abdominal acupuncture treatments all alleviated symptoms of insomnia, depression, and anxiety, but body and auricular acupuncture had stronger therapeutic effects. Conclusions. Body acupuncture at basic points shall be given priority in protocol selection for insomnia. The second-best choice is auricular acupuncture with basic points combined with points based on Traditional Chinese Medicine (TCM theories. Abdominal needling with very quick effect can be an alternative protocol with basic points combined with syndrome differentiation points.

    Objective: The hot flash is a common vasomotor disorder that causes distress in menopausal women and that can be debilitating in men with prostate cancer who are treated with androgen deprivation therapy (ADT). The utility of auricular electroacupuncture (AEA) was tested exclusively for a small cohort of men with ADT-induced vasomotor symptoms while the men underwent a course of curative radiotherapy. Materials and Methods: Prior to and during radiotherapy treatment, men with vasomotor symptoms were given repeated questionnaires regarding severity and frequency of hot flashes, quality of life (QoL), and sleep over a 6-week span of an AEA protocol. Each subject's heart rate variability (HRV) was obtained repeatedly every week in an ambulatory setting with a BlueCardio device (BlueCardio, Miami, FL). The AEA intervention was given with a Neurova device (Nunka Corporation, CM Wellness Clinic, Pompano Beach, FL) that used three needles at Master points Sympathetic, Shen Men , and Point Zero, which were located precisely with a bipolar point finder. Intermittent microcurrent stimulation was given every other week for 96 hours, using a cyclic programmed output of 2 hours on and 2 hours off. Results: Of 10 men completing the 6-week protocol, all responded with significantly lower frequency, duration, and severity of vasomotor symptoms; QoL and sleep scores improved significantly. The HRV analysis showed significantly lower low-frequency/high-frequency power ratios in each individual, compared to baseline, that were consistent with the subjective responses. Conclusions: Vasomotor disturbance, caused by gender hormone withdrawal-either naturally or in patients treated with ADT, as in this study-is a well-defined neurophysiologic condition. This disorder is a constellation of findings that reflect autonomic disturbances of excessive sympathetic and reduced parasympathetic activity. AEA intervention with the Neurova device is simple to administer, is well-tolerated, and

    Obesity is a major public health problem. Regulating food intake and promoting metabolism of fat are two important options for treating obesity. Auricular vagus nerve stimulation (AVNS) is considered as an alternative approach to vagal nerve stimulation. The aim of this study was to investigate the effects of AVNS and its mechanisms on obesity in obese rats. Male Sprague-Dawley rats were fed either a high-fat diet (HFD) or a normal diet for 8 wk. Qualified HFD rats were randomly divided into three groups: the HFD group, the AVNS group, and the sham group for 6 wk treatment. Body weight and daily energy intake were recorded weekly. The rats were sacrificed for measurement of weight of bilateral perirenal, epididymal white adipose tissue (WAT), dorsal brown adipose tissue (BAT), and gastric emptying. Serum cholecystokinin (CCK), peptide YY3 to 36 (PYY3-36) and norepinephrine (NE) were assayed by enzyme-linked immunosorbent assay. Real-time quantitative polymerase chain reaction was used to assess the mRNA expressions of CCK subtype receptor a (CCKa) in the antrum, PYY3-36 receptor in the distal ileum, β3-adrenoceptor, and uncoupling protein gene 1 (UCP1) in the BAT. Compared with HFD group, AVNS significantly reduced body weight and epididymal WAT and increased BAT weight, serum NE, mRNA expressions of β3-adrenoceptors, and UCP1 of the BAT, but had no effect on daily energy intake, perirenal WAT weight, gastric emptying, serum levels of CCK and PYY, or mRNA expressions of CCKa receptor and PYY3-36 receptor in the relevant tissues. The sham group, as a comparison group for AVNS, saw less effect in any of the indexes compared with the HFD group. AVNS had more effect on weight loss, reduction of perirenal WAT, and increase of NE, β3-adrenoceptor, and UCP1 than sham. AVNS was more effective in reducing body weight and causing visceral fat loss. Biochemical tests found more NE released in the serum and more β3-adrenoceptor and UCP1 expression in the BAT. All of

    Full Text Available Este trabajo analiza el impacto que ha tenido el surgimiento de gobiernos de izquierda en América Latina en las políticas económicas que se aplican en la región. El artículo presenta y discute datos sociales y económicos de Argentina, Brasil, Chile y Venezuela, países donde la izquierda controla el gobierno, y dos casos contrastantes, Colombia y México, cuyos gobiernos están en manos de partidos de centro-derecha. Tomando como referencia aspectos centrales de las reformas estructurales de la década de los 90, nuestro análisis sugiere que los nuevos gobiernos de izquierda no han transformado la política económica de manera substancial, lo cual se contradice con la fuerte retórica antineoliberal que ha caracterizado a muchos de sus líderes durante las campañas electorales. En este sentido, el artículo finaliza con algunas hipótesis que podrían explicar tal comportamiento.

    Constipation has been identified as a worldwide health problem among elderly people. Currently, it is not effectively relieved by the use of laxatives and lifestyle modification. Previous studies reported promising results in managing constipation with auricular acupressure (AA), although its effectiveness was not affirmed. This study is to evaluate the complementary effects of AA in relieving constipation symptoms and in promoting disease-specific health-related quality of life (HRQOL) among elderly residential care home (RCH) residents in Hong Kong. Randomized placebo-controlled trial. Elderly RCH. Ninety-nine participants were randomly assigned to either experimental group (AA using auricular plasters with magnetic pellets), placebo-controlled group (AA using auricular plasters with Semen Vaccariae), or usual care group (AA using auricular plasters only). AA was applied onto seven auricular acupoints for 10 days. Constipation symptoms and disease-specific HRQOL were measured before AA, at the completion of AA (D10), and at the 10th-day follow-up time (D20). Significant group×time interaction effect was found in the change of satisfaction subscale between the experimental group and placebo-controlled group at D10 (p=0.016) and D20 (p=0.016) relative to the baselines. For both constipation symptoms and disease-specific HRQOL, the experimental group demonstrated the greatest improvement after receiving AA at both D10 and D20 compared with the other two groups. The current findings indicated positive clinical value of AA with magnetic pellets in managing constipation in elderly RCH residents. AA was also found to be a safe and acceptable intervention.

    Full Text Available Introducción: El envejecimiento incrementa el riesgo de trombosis y fenómenos embólicos, trae cambios fisiológicos y comorbilidades como la fibrilación auricular que hacen complejo el inicio y la seguridad de la anticoagulación. Apesar de la mayor disponibilidad de clínicas de anticoagulación y nuevos anticoagulantes orales, es bajo el porcentaje de adultos mayores que están anticoagulados aunque tengan indicación plena y ausencia de contraindicaciones. Objetivo: Revisar las principales estrategias para predecir y disminuir el riesgo de sangrado con el empleo de anticoagulantes orales en pacientes adultos mayores frágiles. Metodología: Se realizó una búsqueda sistemática sobre estudios que evaluaran la seguridad y eficacia de anticoagulantes orales en pacientes con fibrilación auricular en adultos mayores de 65 años, y una búsqueda de estudios sobre el síndrome de fragilidad y su impacto en el adulto mayor anticoagulado. Resultados y Discusión: Se ha denominado fragilidad al porcentaje de adultos mayores que presentan un mayor deterioro de sus sistemas biológico, físico y cognitivo, conduciendo a una mayor probabilidad de desenlaces adversos en salud, discapacidad y muerte. Se han estudiado características clínicas que permiten identificar pacientes como frágiles; el fenotipo de fragilidad de Linda Fried evalúa esas características; además, existen estrategias de monitoreo de los anticoagulantes orales que deben ser conocidos para minimizar el riesgo de eventos adversos. Conclusiones: el anciano frágil presenta factores de riesgo que probablemente afectan la eficacia y seguridad de la terapia con anticoagulantes orales. Las guías clínicas existentes no proveen la suficiente evidencia y no consideran de manera multidimensional al paciente geriátrico.

    Full Text Available We evaluated the dynamics of ear infestations caused by Rhabditis spp. and Raillietia spp., which were correlated with animal age, intensity of clinical signs and climate factors. Sixty-four Gir cattle were distributed into three groups: GA - 23 calves with 4 to 6 months of age; GB - 18 calves with 7 to 12 months of age; and GC - 23 heifers with 13 to 33 months of age. Five samplings, defined as S1, S2, S3, S4 and S5 were performed every three months from August 2008 to August 2009. The ear secretion was collected using the auricular washing method for the right ear and a swab for the left ear. A clinical assessment of the animals was performed, and they were classified according to the presence and severity of otitis. The highest relative frequency of rhabditosis was 52.2% in GC at the last sampling. In the first sampling, 42.2% of the animals were infested by Raillietia spp. The older cattle were more susceptible to infestations by both parasites. No correlation of Rhabditis spp. and Raillietia spp. parasitism with climate factors was found. The results showed that both parasites could infest Gir cattle, and in most cases, there was no co-infestation. Only older animals parasitized by the nematode showed clinical signs of the disease.Avaliou-se a dinâmica da infestação auricular causada por Rhabditis spp. e por Raillietia spp., relacionando-a com a idade dos animais, com a intensidade dos sinais clínicos e com os fatores climáticos.

    Full Text Available A partir de un ejercicio de lectura comparativa de diez y siete obras literarias colombianas publicadas en las décadas de 1970 y 1980, entre novelas y cuentos, se busca debatir sobre la manera en que fue representada ficcionalmente la extrema izquierda armada en el país. El interés en explorar la narrativa deviene de la creciente importancia de su función testimonial para el análisis de fenómenos sociopolíticos. La literatura, en tanto discurso dotado de múltiples significados, fue durante el periodo estudiado, un arte politizado y un vehículo para la denuncia de asimetrías sociales, capaz de recoger tipos sociales densamente considerados que ilustran la interacción de grupos humanos y el poder político. El artículo pretende aportar a los estudios en torno a las relaciones literatura-política, los cuales en Colombia hoy están ligados a la construcción de la idea de nación, las guerras civiles del siglo XIX, la Violencia de los años 50 del siglo XX y recientemente al narcotráfico.

No hubo ruptura con el exilio y, por tanto, refundación del PSOE y del PCE debido a la presencia cualificada de históricos de la guerra civil y de miembros de la segunda generación del exilio/primera clandestinidad en los círculos de poder interno de ambos partidos. Pero, sobre todo, no hubo refundación del PSOE tras Suresnes por la continuidad de aspectos claves de su política y por el peso de la conciencia histórica del franquismo en la cultura política de los socialistas.The author aims to show that the evolution of tehe Parliamnetary left wing is ultimately roots on the exile. PSOE anf PCE never broke their links with the exile and therefore were never refounded, due to the leading presence of persons who played a role in the civil war as well as of members of the second generation of the exile and the first underground movements in the core of both partios. Over all, the PSOE was never refounded after Suresnes as the key features of its politics remaied unchanged and historical conscience of francoism played a decisive part in the Socialist political culture.

    Laser cartilage reshaping (LCR) with cryogen spray cooling is a promising modality for producing cartilage shape change while reducing cutaneous thermal injury. However, LCR in thicker tissues, such as auricular cartilage, requires higher laser power, thus increasing cooling requirements. To eliminate the risks of freeze injury characteristic of high cryogen spray pulse rates, a carbon dioxide (CO2) spray, which evaporates rapidly from the skin, has been proposed as the cooling medium. This study aims to identify parameter sets which produce clinically significant reshaping while producing minimal skin thermal injury in LCR with CO2 spray cooling in ex vivo rabbit auricular cartilage. Excised whole rabbit ears were mechanically deformed around a cylindrical jig and irradiated with a 1.45-μm wavelength diode laser (fluence 12-14 J/cm(2) per pulse, four to six pulse cycles per irradiation site, five to six irradiation sites per row for four rows on each sample) with concomitant application of CO2 spray (pulse duration 33-85 ms) to the skin surface. Bend angle measurements were performed before and after irradiation, and the change quantified. Surface temperature distributions were measured during irradiation/cooling. Maximum skin surface temperature ranged between 49.0 to 97.6 °C following four heating/cooling cycles. Significant reshaping was achieved with all laser dosimetry values with a 50-70 °C difference noted between controls (no cooling) and irradiated ears. Increasing cooling pulse duration yielded progressively improved gross skin protection during irradiation. CO2 spray cooling may potentially serve as an alternative to traditional cryogen spray cooling in LCR and may be the preferred cooling medium for thicker tissues.

    Laser cartilage reshaping (LCR) with cryogen spray cooling is a promising modality for producing cartilage shape change while reducing cutaneous thermal injury. However, LCR in thicker tissues, such as auricular cartilage, requires higher laser power, thus increasing cooling requirements. To eliminate the risks of freeze injury characteristic of high cryogen spray pulse rates, a carbon dioxide (CO2) spray, which evaporates rapidly from the skin, has been proposed as the cooling medium. This study aims to identify parameter sets which produce clinically significant reshaping while producing minimal skin thermal injury in LCR with CO2 spray cooling in ex vivo rabbit auricular cartilage. Excised whole rabbit ears were mechanically deformed around a cylindrical jig and irradiated with a 1.45-μm wavelength diode laser (fluence 12–14 J/cm2 per pulse, four to six pulse cycles per irradiation site, five to six irradiation sites per row for four rows on each sample) with concomitant application of CO2 spray (pulse duration 33–85 ms) to the skin surface. Bend angle measurements were performed before and after irradiation, and the change quantified. Surface temperature distributions were measured during irradiation/cooling. Maximum skin surface temperature ranged between 49.0 to 97.6 °C following four heating/cooling cycles. Significant reshaping was achieved with all laser dosimetry values with a 50–70 °C difference noted between controls (no cooling) and irradiated ears. Increasing cooling pulse duration yielded progressively improved gross skin protection during irradiation. CO2 spray cooling may potentially serve as an alternative to traditional cryogen spray cooling in LCR and may be the preferred cooling medium for thicker tissues. Future studies evaluating preclinical efficacy in an in vivo rabbit model are in progress. PMID:23307439

    Full Text Available El artículo recorre la trayectoria de militantes argentinos, bolivianos, chilenos y uruguayos que desarrollaron una red regional de organizaciones armadas de izquierda. Los intercambios entre estas organizaciones que demoraran más de diez años, comenzaron con las redes de apoyo a la incursión del Che Guevara a Bolivia en 1966 y finalizaron en los tardíos setentas cuando el golpe de estado en Argentina canceló el último refugio en la región. Para entender la evolución que culminó en el desarrollo de una estrategia continental se examina la confluencia del ERP Argentino, el ELN Boliviano, el uruguayo MLN-Tupamaros y el chileno MIR a través de eventos críticos que definieron la experiencia de esta red de militantes: el impacto de la guerrilla boliviana del Che, los intercambios políticos y culturales desarrollados entre militantes de estas organizaciones en el Chile de Allende, y la creación de una organización regional llamada la Junta de Coordinación Revolucionaria. Este articulo usa una perspectiva transnacional para examinar un tema que hasta ahora ha sido examinado mayoritariamente desde una perspectiva nacional o comparativa. El artículo busca mostrar cómo la región fue un espacio central de experimentación en la constitución de identidades políticas. Asimismo, defiende que solo un enfoque transnacional puede ayudar a dar una más completa explicación acerca de la emergencia de estos movimientos políticos radicales durante el período

    Full Text Available The purpose of this study was to analyze and compare intra and intergroup the immediate effect of the auricular and LR8 systemic acupuncture on the electromyographic activity of the trapezius with the trigger points. This is an experimental clinical trial; 40 people were split in 4 distinct groups (n = 10: GI mustard seed application in the auricular acupoint; GII bilateral needle application in the LR8 acupoint; GIII combination of the techniques; GIV/Control Group mustard seed application in an acupoint not linked to the muscle tension. The EMG was used to assess the muscle contraction for 5 seconds during the resting time and during the isometric contraction time. The EMG signal was first collect without the acupuncture intervention; then both techniques were applied for 5 minutes; and the EMG was collected again right after these applications. The Shapiro-Wilk test was used, the t test was paired with the Wilcoxon test to the intragroup comparison; One-way analysis of variance test for intergroup comparison. There was no statistical difference in the intragroup comparison for the groups. The same happened to the intergroup comparison before and after application. Systemic and auricular acupuncture did not promote immediate changes in the EMG activity of the trapezius muscle in individuals with MTrPs.

    Full Text Available La fibrilación auricular es la arritmia cardiaca sostenida más común y su prevalencia se duplica cada decenio por encima de los cincuenta años. Entretanto, las condiciones clínicas que más se asocian con ésta son la hipertensión arterial, la insuficiencia cardíaca, la enfermedad valvular cardíaca y la diabetes mellitus. Como complicaciones está la falla cardiaca, pero tal vez una de las peores son los eventos cardioembólicos, que ocurren aproximadamente en 4,5% de los pacientes no anticoagulados. El tratamiento antitrombótico con antagonistas de la vitamina K fue, durante más de cincuenta años, la única alternativa disponible, a pesar de sus múltiples limitaciones, las mismas que llevaron al desarrollo de nuevos fármacos anticoagulantes que disminuyen muchos de los problemas de los antagonistas de la vitamina K. Pueden agruparse en dos clases: inhibidores orales directos de la trombina e inhibidores orales del factor X activado. Tanto dabigatrán, rivaroxabán como apixabán, cuentan ya con estudios clínicos controlados aleatorizados que apoyan su uso en el tratamiento antitrombótico de la fibrilación auricular y recientemente se incluyeron en las guías basadas en la evidencia como alternativa (ACC e incluso con un grado de recomendación superior (CCS, CHEST al de los antagonistas de la vitamina K.Atrial fibrillation is the most common sustained cardiac arrhythmia and its prevalence doubles every decade for people older than fifty years.

    Primary cervical dystonia is characterized by abnormal, involuntary, and sustained contractions of cervical muscles. Current ways of treatment focus on alleviating symptomatic muscle activity. Besides pharmacological treatment, in severe cases patients may receive neuromodulative intervention such as deep brain stimulation. However, these (highly invasive) methods have some major drawbacks. For the first time, percutaneous auricular vagus nerve stimulation (pVNS) was applied in a single case of primary cervical dystonia. Auricular vagus nerve stimulation was already shown to modulate the (autonomous) sympathovagal balance of the body and proved to be an effective treatment in acute and chronic pain, epilepsy, as well as major depression. pVNS effects on cervical dystonia may be hypothesized to rely upon: (i) the alteration of sensory input to the brain, which affects structures involved in the genesis of motoric and nonmotoric dystonic symptoms; and (ii) the alteration of the sympathovagal balance with a sustained impact on involuntary movement control, pain, quality of sleep, and general well-being. The presented data provide experimental evidence that pVNS may be a new alternative and minimally invasive treatment in primary cervical dystonia. One female patient (age 50 years) suffering from therapy refractory cervical dystonia was treated with pVNS over 20 months. Significant improvement in muscle pain, dystonic symptoms, and autonomic regulation as well as a subjective improvement in motility, sleep, and mood were achieved. A subjective improvement in pain recorded by visual analog scale ratings (0-10) was observed from 5.42 to 3.92 (medians). Muscle tone of the mainly affected left and right trapezius muscle in supine position was favorably reduced by about 96%. Significant reduction of muscle tone was also achieved in sitting and standing positions of the patient. Habituation to stimulation leading to reduced stimulation efficiency was observed and

    Full Text Available La reconstrucción auricular es una de las más difíciles ya que implica reproducir las sofisticadas y delicadas formas del pabellón auricular. Cuando hay que resecar piel en la oreja por un cáncer cutáneo y dejamos expuesto el cartílago, sin pericondrio, suele suceder que al colocar injertos no hay una integración adecuada de los mismos por las caprichosas formas y relieves del pabellón auricular; cuando es necesario resecar el pericondrio estamos obligados a cubrir el defecto con un colgajo y no con un simple injerto. Frente a esta dificultad técnica, diseñamos un colgajo ricamente vascularizado que preserva el cartílago no afectado con una buena cubierta y al mismo tiempo respeta la anatomía de la oreja. Para la cobertura del cartílago auricular anterior usamos un colgajo fasciocutáneo posterior que se asemeja a un plato típico de la cocina mexicana que llamamos "quesadilla", donde el cartílago por su color blanco recuerda el queso y el gran colgajo fasciocutaneo recuerda la tortilla que cubre al queso. Este colgajo incluye la piel enrollada del hélix, que en un segundo tiempo retornará a su lugar de origen anatómico mediante una z-plastía asimétrica. Presentamos, de entre una serie de 13 pacientes con carcinoma de pabellón auricular, 2 casos resueltos mediante esta técnica.Auricle reconstruction is one of the most difficult techniques because of the sophisticated and delicates forms of the ear. When we need to remove the auricular skin, preserving the cartilage is very important to keep the shape of the auricle. If treating an auricular skin cancer we find an unaffected cartilage, we can use a skin grafting, but in such delicates forms and curves many times it results inappropriate or the lack of pericondrium difficult skin graft integration. When pericondrium is affected, we will need a skin flap to cover de defect. We designed a rich vascularized flap that preserves the unaffected cartilage with an adequate coverage

In this study, we investigated the curative effect of auricular acupuncture and somatic acupuncture on kainic acid- (KA- induced epilepsy in rats. Methods. We established an epileptic seizure model in rats by KA (12 mg, ip. The 2 Hz electroacupuncture (EA was applied at auricular and applied at Zusanli and Shangjuxu (ST36-ST37 acupoints for 20 min for 3 days/week for 6 weeks beginning on the day following the KA injection. Results. The electrophysiological results indicated that neuron overexcitation occurred in the KA-treated rats. This phenomenon could be reversed among either the auricular EA or ST36-ST37 EA treatment, but not in the sham-control rats. The Western blot results revealed that TRPA1, but not TRPV4, was upregulated by injecting KA and could be attenuated by administering auricular or ST36-ST37 EA, but not in the sham group. In addition, potentiation of TRPA1 was accompanied by increased PKCα and reduced PKCε. Furthermore, pERK1/2, which is indicated in inflammation, was also increased by KA. Furthermore, the aforementioned mechanisms could be reversed by administering auricular EA and could be partially reversed by ST36-ST37 EA. Conclusions. These results indicate a novel mechanism for treating inflammation-associated epilepsy and can be translated into clinical therapy.

    Full Text Available This prospective, randomized clinical trial (RCT pilot study was designed to (1 assess the feasibility and tolerability of an easily administered, auricular point acupressure (APA intervention and (2 provide an initial assessment of effect size as compared to a sham treatment. Thirty-seven subjects were randomized to receive either the real or sham APA treatment. All participants were treated once a week for 4 weeks. Self-report measures were obtained at baseline, weekly during treatment, at end-of-intervention (EOI, and at a 1-month follow-up. A dropout rate of 26% in the real APA group and 50% in the sham group was observed. The reduction in worst pain from baseline to EOI was 41% for the real and 5% for the sham group with a Cohen’s effect size of 1.22 P<0.00. Disability scores on the Roland Morris Disability Questionnaire (RMDQ decreased in the real group by 29% and were unchanged in the sham group (+3% P<0.00. Given the high dropout rate, results must be interpreted with caution; nevertheless, our results suggest that APA may provide an inexpensive and effective complementary approach for the management of back pain in older adults, and further study is warranted.

    Full Text Available To explore new noninvasive treatment options for depression, this study investigated the effects of electroacupuncture (EA at the auricular concha region (ACR of depression rat models. Depression in rats was induced by unpredictable chronic mild stress (UCMS combined with isolation for 21 days. Eighty male Wistar rats were randomly assigned into four groups: normal, UCMS alone, UCMS with EA-ACR treatment, and UCMS with EA-ear-tip treatment. Rats under inhaled anesthesia were treated once daily for 14 days. The results showed that blood pressure and heart rate were significantly reduced in the EA-ACR group than in the UCMS alone group or the EA-ear-tip group. The open-field test scores significantly decreased in the UCMS alone and EA-ear-tip groups but not in the EA-ACR group. Both EA treatments downregulated levels of plasma cortisol and ACTH in UCMS rats back to normal levels. The present study suggested that EA-ACR can elicit similar cardioinhibitory effects as vagus nerve stimulation (VNS, and EA-ACR significantly antagonized UCMS-induced depressive status in UCMS rats. The antidepressant effect of EA-ACR is possibly mediated via the normalization of the hypothalamic-pituitary-adrenal (HPA axis hyperactivity.

    To identify and prioritise indicators to assess the quality of care and safety of patients with non-valvular auricular fibrillation (NVAF) and deep vein thrombosis (DVT) treated with anticoagulants. Using the consensus conference technique, a group of professionals and clinical experts, the determining factors of the NVAF and DVT care process were identified, in order to define the quality and safety criteria. A proposal was made for indicators of quality and safety that were prioritised, taking into account a series of pre-established attributes. The selected indicators were classified into indicators of context, safety, action, and outcomes of the intervention in the patient. A set of 114 health care and safety quality indicators were identified, of which 35 were prioritised: 15 for NVAF and 20 for DVT. About half (49%) of the indicators (40% for NVAF and 55% for DVT) applied to patient safety, and 26% (33% for NVAF and 20% for DVT) to the outcomes of interventions in the patient. The present work presents a set of agreed indicators by a group of expert professionals that can contribute to the improvement of the quality of care of patients with NVAF and DVT treated with anticoagulants.

    To assess the effectiveness and safety on post-stroke dysphagia in chronic stage treated with magnetic-ball sticking therapy at the auricular points. Ninety cases of post-apoplexy dysphagia in chronic stage were randomized into an auricular points group and an acupuncture group. In the auricular points group, the magnetic-ball sticking therapy was applied to subcortex (pizhixia, AT4), brainstem (naogan, AT(3,4i)), mouth (kou, CO1), cheek (mianjia, LO(5,6i)), tongue (she, LO2) and throat (yanhou, TG3) on one ear each time, and were changed on the other ear once every 3 days. In the acupucnture group, acupuncture was applied to Feng-chi (GB 20), Yifeng (TE 17), Shanglianquan (Extra), Jinjin (EX-HN 12), Yuye (EX-HN 13), Shuigou (GV 26) and Tongli (TH 5), etc. The needles were retained for 30 min in each treatment. The treatment was gi-yen once a day in the two groups and the treatment of 6 days made one session. There was 1 day at an interval among the sessions. Totally, 3 sessions of treatment were required. The video fluoroscopic swallowing study (VFSS) was performed for 4 kinds of food with different properties and shapes in each patient. The main indices were Rosenbek penetration-aspiration score, oral-retaining score and throat-retaining score. The efficacy, and the incidences of aspiration pneumonia and malnutrition were compared between the two groups. The nutrition indices were compared before and after treatment between the two groups, such as the skinfold thickness of triceps brachii muscle, serum albumin and peralbumin. In 21 days of treatment, in the auricular points group, the 1 mL liquid loversol Rosenbek penetration-aspiration score (1.51 +/- 0.69), oral-retaining score (1.17 +/- 0.38) and throat-retaining score (1.30 +/- 0.66) were all lower than those (2.51 +/- 0.67, 1.63 +/- 0.72, 1.67 +/- 0.7) in the acupuncture group separately.

    To compare the clinical efficacy on cervical spondylotic radiculopathy between the combined therapy of massage and magnetic-sticking at the auricular points and the simple massage therapy, and conduct the health economics evaluation. Seventy-two patients of cervical spondylotic radiculopathy were randomized into a combined therapy group, and a simple massage group, 36 cases in each one. Finally, 35 cases and 34 cases were met the inclusive criteria in the corresponding groups separately. In the combined therapy group, the massage therapy and the magnetic sticking therapy at auricular points were combined in the treatment. Massage therapy was mainly applied to Fengchi (GB 20), Jianjing (GB 21), Jianwaishu (SI 14), Jianyu (LI 15) and Quchi (LI 11). The main auricular points for magnetic sticking pressure were Jingzhui (AH13), Gan (On12) Shen (CO10), Shenmen (TF4), Pizhixia (AT4). In the simple massage group, the simple massage therapy was given, the massage parts and methods were the same as those in the combined therapy group. The treatment was given once every two days, three times a week, for 4 weeks totally. The cervical spondylosis effect scale and the simplified McGill pain questionnaire were adopted to observe the improvements in the clinical symptoms, clinical examination, daily life movement, superficial muscular pain in the neck and the health economics cost in the patients of the two groups. The effect was evaluated in the two groups. The effective rate and the clinical curative rate in the combined therapy group were better than those in the control group [100. 0% (35/35) vs 85. 3% (29/34), 42. 9% (15/35) vs 17. 6% (6/34), both P<0. 05].

    Full Text Available Abstract Background Evidence supports the use of exercise for chronic low back pain (CLBP; however, adherence is often poor due to ongoing pain. Auricular acupuncture is a form of pain relief involving the stimulation of points on the outer ear corresponding with specific body parts. It may be a useful adjunct to exercise in managing CLBP; however, there is only limited evidence to support its use with this patient group. Methods/Design This study was designed to test the feasibility of an assessor-blind randomised controlled trial which assess the effects on clinical outcomes and exercise adherence of adding manual auricular acupuncture to a personalised and supervised exercise programme (PEP for CLBP. No sample size calculation has been carried out as this study aims to identify CLBP referral rates within the catchment area of the study site. The researchers aim to recruit four cohorts of n = 20 participants to facilitate a power analysis for a future randomised controlled trial. A computer generated random allocation sequence will be prepared centrally and used to allocate participants by cohort to one of the following interventions: 1 six weeks of PEP plus manual auricular acupuncture; 2 six weeks of PEP alone. Both groups will also complete a further six weeks of self-paced exercise with telephone follow-up support. In addition to a baseline and exit questionnaire at the beginning and end of the study, the following outcomes will be collected at baseline, and after 7, 13 and 25 weeks: pain frequency and bothersomeness, back-specific function, objective assessment and recall of physical activity, use of analgesia, perceived self-efficacy, fear avoidance beliefs, and beliefs about the consequences of back pain. Since this is a feasibility study, significance tests will not be presented, and treatment effects will be represented by point estimates and confidence intervals. For each outcome variable, analysis of covariance will be performed on

    Full Text Available The aim of this study was to investigate the synergistic antioxidant potential and protective effect of grape seed procyanidins (GSP in combination with Auricularia auricular-judae polysaccharides (AAP IV on radiation injury in splenocytes. Rat splenocyte irradiation resulted in significantly higher apoptosis rate, malondialdehyde (MDA (p < 0.005, reactive oxygen species (ROS (p < 0.01; cell viability, total superoxide dismutase (T-SOD (p < 0.01, catalase (CAT (p < 0.01, glutathione peroxidase (GSH-PX (p < 0.05, activity and glutathione (GSH (p < 0.01 levels were significantly reduced, compared with the control group. “GSP + AAP IV” treatment of rat splenocytes at doses of “GSP (0.3 μg/mL + AAP IV (50 μg/mL” displayed higher radioprotective and antioxidative effects than the administration of either GSP or AAP IV, as evident by lower levels of MDA (p < 0.001 concentration, as well as higher cell viability and T-SOD (p < 0.05, CAT (p < 0.005, GSH-PX (p < 0.01 and GSH content compared to the radiation group. In addition, in vivo studies have shown that “GSP + AAP IV” significantly ameliorated the decrease of spleen index (p < 0.005 and spleen GSH (p < 0.005 levels and significantly inhibited the increase of MDA (p < 0.005 levels of spleen with radiation-induced damage, compared with the non-treated group. The in vivo and in vitro results suggested that GSP and AAP IV have a synergistic protective effect against radiation-induced injury by improving the antioxidant and immunomodulation activities.

    The activity of the VN (vagus nerve) is negatively associated with risk factors such as stress and smoking, morbidity and mortality. In contrast, it is also a target of therapeutic intervention. VN stimulation is used in depression and epilepsy. Because of its high invasivity and exclusive application to therapy-resistant patients, there is interest in less invasive methods affecting the VN. Several studies examining acupuncture report beneficial effects on vagal activity. However, findings are inconsistent, and applied methods are heterogeneous resulting in difficulties in interpretation. The purpose of the present study was evaluation of the effects of acupuncture on vagal activity in a three-armed randomized trial while controlling several disturbing factors. Fourteen healthy men participated in random order in four examinations: a control condition without intervention, a condition with placebo, manual acupuncture and electroacupuncture. Acupuncture was conducted on the concha of the ear, as there is neuroanatomical evidence for vagal afferents. Each examination took place once, with a week's time between examinations. RSA(TR) (respiratory sinus arrhythmia adjusted for tidal volume) indicating vagal activity was measured continuously. The study was conducted partially blind in accordance with recommendations. After controlling for respiration,condition-specific pain sensation, individual differences in belief of acupuncture effectiveness and time effects not attributable to the interventions, electroacupuncture but not manual acupuncture was found to have a positive effect on RSA(TR). The results underline the potential role of auricular electrical stimulation to induce an increase in vagal activity, and it therefore might be used as preventive or adjuvant therapeutic intervention promoting health.

  3. The Importance of a Conchal Bowl Element in the Fabrication of a Three-Dimensional Framework in Total Auricular Reconstruction

    Full Text Available BackgroundTo construct a sophisticated three-dimensional framework, numerous modifications have been reported in the literature. However, most surgeons have paid little attention to the anatomical configuration of the concha and more to its deepness and hollowness, leading to unsatisfactory outcomes.MethodsFor a configuration of the concha that is definitely anatomical, the author further developed and employed the conchal bowl element, which has been used by several surgeons although the results have not been published elsewhere. The author constructed the conchal bowl element in one of three patterns according to the amount of available cartilages: one block, two-pieces, or a cymba bowl element only. A total of 20 patients underwent auricular reconstruction using a costal cartilage framework between 2009 and 2012. The 8 earliest reconstructions were performed without a conchal bowl element and the latter 12 with a conchal bowl element. The patients were followed up for more than 1 year. The aesthetic results were scored by evaluating characteristics involving the stability of the crus helicis, the conchal definition, and the smoothness of the helical curve.ResultsThe ears reconstructed early without a conchal bowl element showed a shallow and one or two incompletely separated concha with an obliterated cymba conchal space. They also did not have a realistic or smooth curve of the helix because of an unstable crus helicis. However, ears reconstructed later with the concha bowl element showed a definite crus helicis, deep cymba conchal space, and smooth helical curve.ConclusionsThe construction of the conchal bowl element is simple, not time-consuming procedure. It is suggested that the conchal bowl element must be constructed and attached to the main framework for natural configuration of the reconstructed ear.

Although the dissection method has been improved by retaining some tissues to reduce complications, the incomplete dissection may cause recurrence of disease. In the present study, we developed a novel radical neck dissection, which preserves the external jugular vein, the greater auricular nerve, and the deep branches of the cervical nerve, to effectively reduce complications and subsequently, to promote the postoperative survival quality. Methods: A total of 100 cases of radical neck dissection were retrospectively analyzed to evaluate the efficacy, rate of complication, and postoperative dysfunction of patients treated with the novel radical neck dissection. Data analysis was performed using the Chi-square test. Results: Compared with conventional radical neck dissection, the novel radical neck dissection could significantly reduce complications and promote postoperative survival quality. Particularly, the preservation of the external jugular vein reduced the surgical risk (ie, intracranial hypertension and complications (eg, facial edema, dizziness, headache. Preservation of the deep branches of the cervical nerve and greater auricular nerve resulted in relatively ideal postoperative functions of the shoulders and ear skin sensory function (P 0.05. Conclusion: Our novel radical neck dissection procedure could effectively reduce the complications of intracranial hypertension, shoulder dysfunction, and ear sensory disturbances.

    Full Text Available Los defectos del tercio superior auricular son un desafío reconstructivo. Están descritas diferentes técnicas quirúrgicas para este fin con resultados a veces desfavorables Realizamos un estudio anatómico en cadáveres frescos que mostró la presencia constante de un pedículo neurovascular que penetra la raíz del hélix. Mostramos la localización y los diámetros de los vasos. Basándonos en este estudio anatómico, presentamos una serie de 10 casos consecutivos tratados por el autor principal. Analizamos la etiología, técnica quirúrgica, complicaciones y resultado a largo plazo. La técnica del autor introduce refinamientos a la técnica de Davis, el cual usa un colgajo condrocutáneo de concha auricular basado en la rama superior de la arteria temporal superficial y un colgajo cutáneo axial de base superior basado en la arteria retroauricular, para crear el nuevo hélix auricular superior. El aspecto posterior de este colgajo condrocutáneo se cubre con un injerto de piel total. En un segundo tiempo empleamos una zetaplastia de la base del hélix que nos dará una mejor forma. El estudio anatómico demostró la presencia de un pedículo neurovascular que penetra la raíz del hélix. La serie clínica está compuesta por 8 defectos postraumáticos, una quemadura eléctrica y un tumor de piel. Todos los colgajos condrocutáneos de concha auricular sobrevivieron comprobándose la seguridad del pedículo del hélix. Dos colgajos retroauriculares presentaron sufrimiento vascular transitorio distal, uno de ellos con recuperación completa y otro con necrosis distal mínima. Dos casos sufrieron pérdida parcial del injerto de piel total. Durante el desarrollo de la serie descubrimos algunos detalles de la técnica quirúrgica, que ahora discutimos en el artículo. Todos los pacientes recuperaron el contorno auricular, obteniendo los mejores resultados en aquellos en los que se aplicaron los refinamientos descritos. En conclusión, creemos

    Percutaneous stimulation of the auricular branch of the vagus nerve (pVNS) by miniaturized needle electrodes in the auricle gained importance as a treatment for acute and chronic pain. The objective is to establish a realistic numerical model of pVNS and investigate the effects of stimulation waveform, electrodes' depth, and electrodes' position on nerve excitation threshold and the percentage of stimulated nerves. Simulations were performed with Sim4Life. An electrostatic solver and neural tissue models were combined for electromagnetic and neural simulation. The numerical model consisted of a realistic high-resolution model of a human ear, blood vessels, nerves, and three needle electrodes. A novel 3D ear model was established, including blood vessels and nerves. The electric field distribution was extracted and evaluated. Maximum sensitivity to needles' depth and displacement was evaluated to be 9.8 and 15.5% per 0.1 mm, respectively. Stimulation was most effective using biphasic compared to mono-phasic pulses. The established model allows easy and quantitative evaluation of various stimulation setups, enabling optimization of pVNS in experimental settings. Results suggest a high sensitivity of pVNS to the electrodes' position and depth, implying the need for precise electrode positioning. Validation of the model needs to be performed.

    Full Text Available La fibrilación auricular (FA es la arritmia sostenida más frecuente, con una prevalencia en la población general del 1-2%, que aumenta con la edad y la presencia de cardiopatía concomitante. Aunque el Cox-maze III tiene unas tasas de éxito mayores del 90%, su dificultad técnica ha hecho que surjan distintas técnicas alternativas. En la actualidad disponemos de distintas fuentes de energía y se han descrito múltiples patrones de lesiones para el tratamiento tanto de la FA asociada a cardiopatía como de la FA aislada. La European Association for Cardiothoracic Surgery (EACTS ha realizado un resumen de las distinta guías publicadas y además ha revisado la evidencia y propuesto recomendaciones para aquellos aspectos que no eran abordados en dichas guías. Sus principales conclusiones son que la cirugía de la FA en los pacientes con cardiopatía asociada disminuye su incidencia en el seguimiento, y que existe cierta evidencia de que esto se traduce en menor riesgo de ictus, insuficiencia cardiaca y mortalidad. Además, la cirugía debe ser considerada en aquellos pacientes en los que la ablación con catéter fracasa o en aquellos en los que esté contraindicada o sea preferida por el paciente.

    Full Text Available Introducción: el propósito del estudio fue evaluar el eficacia de la cirugía de Maze III modificada mediante una pinza de crioablación reutilizable en comparación con el Maze III clásico de corte y sutura, sólo en pacientes con fibrilación auricular permanente, y a la vez realizar cirugía mitral. Métodos: desde mayo de 1993 a abril de 2005, se realizó cirugía de Maze a 134 pacientes, de los cuales 92 presentaban fibrilación auricular permanente y además tenían cirugía de la válvula mitral. En el grupo clásico de Maze se incluyeron 71 pacientes (grupo I y en el nuevo grupo 21 (grupo II. Se realizó un análisis multivariable para analizar estos resultados. Resultados: la edad promedio fue 48,1 años (24 a 67 años, en un total de 24 hombres y 68 mujeres. La duración de la fibrilación fue de 3,8 años ± 4,3 años (DE 0,5-20 y el promedio del diámetro de la aurícula izquierda fue de 57 (26-82. No se hallaron diferencias significativas en ambos grupos. El tiempo de isquemia del grupo I fue de 83 min y del grupo II de 77 min (p = 0,4. El sangrado post-quirúrgico fue de 762 mL en el grupo I y 680 para el grupo II (p= 0,6. La mortalidad en el grupo I fue de 5,6% y en el grupo II de 0%. El ritmo sinusal se recobró en el 87% de los pacientes del grupo I y en el 85,7% del grupo II. Conclusiones: la cirugía de Maze III modificada con pinza de crioablación reutilizable, es tan efectiva como el Maze clásico, que se considera el patrón de oro. Se encontró una disminución en el tiempo de isquemia y en el riesgo de sangrado post-quirúrgico, la cual fue no significativa estadísticamente. Hay diferencia en la mortalidad de los dos grupos. Esta modificación es segura y puede aplicarse por un mayor número de cirujanos en cualquier institución. En países que se encuentran en vía de desarrollo este aparato puede utilizarse como un método alterno de energía.Introduction: the purpose of this study was to evaluate the efficacy of

    We report two cases of left paraduodenal internal hernias located in the fossa of Landzert that were diagnosed by CT. Internal hernias are an infrequent cause of acute abdomen, due to the intestinal sub occlusion they produce. Left paraduodenal hernias are responsible for about 50% of internal hernias. CT makes it possible to demonstrate the group of herniated loops between the stomach, fourth segment of the duodenum, descending colon, and tail of the pancreas. The identification of the loops in an atypical position together with displaced blood vessels (mesenteric vessels) and colon gives concerns on them a typical radiological semiology that makes them easily identifiable.

    Substance abuse has been prevalent in Malaysia for many years and currently represents one of the main concerns to its society. The limitations of conventional therapies have resulted in efforts to explore the potentia of complementary therapies in the management of drug addiction. The evidence for auricular acupuncture (AA) as a potential complementary therapy for drug addiction is still limited and inconclusive. The study intended (1) to compare the clinical outcomes of methadone maintenance treatment (MMT) alone and MMT plus AA (MMT+AA) with regard to the daily methadone dose, number of cigarettes smoked/wk, relapse rates, and withdrawal symptoms; (2) to evaluate health-related quality of life (HR QoL) pre- and postintervention; and (3) to determine participants' acceptance of AA therapy. The research team designed this study to be prospective, longitudinal, open-labeled, and randomized, with one intervention group (AA group) and one control group. The settings were three MMT centers in Terengganu, Malaysia: (1) the Methadone Maintenance Treatment (MMT) Center, Hospital Sultanah Nur Zahirah; (2) the MMT Center, Marang Health Clinic; and (3) the MMT Center, Seberang Takir Health Clinic. Participants were individuals who were enrolled in the three MMT programs. After randomization, the intervention group received MMT+AA while the control group received MMT only. Participants in the AA group underwent concurrent AA sessions for 8 wk. All outcomes were evaluated using questionnaires that the research team developed and WHOQOL-BREF. Data were analysed employing descriptive and nonparametric statistics (SPSS v16). A total of 97, eligible, male patients consented to participation (MMT = 42; MMT+AA = 55; median age = 36.0 y; Malay ethnicity = 97.9%). After screening for dropouts, the data from only 69 participants were considered for postintervention analysis (MMT = 40; MMT+AA = 29).

    enema para tratamiento de la manifestación izquierda leve o moderada de la enfermedad. Este antecedente sirvió de base para evaluar la eficacia y perfil de seguridad de una solución viscosa del producto. Métodos: fueron aleatorizados 31 pacientes hacia tres grupos de tratamiento diario durante 14 días. Doce recibieron enemas de 10 mg de factor de crecimiento epidérmico en 100 mL de solución viscosa, mientras nueve fueron tratados con enemas placebo conteniendo solamente solución viscosa. Ambos grupos recibieron además 1,2 g diarios de mesalacina oral. El tercer grupo incluyó 10 pacientes con mesalacina en enemas de 3g / 100 mL. La variable principal de eficacia fue la respuesta clínica al finalizar las dos semanas de tratamiento, definida como la disminución de, al menos tres puntos, el índice basal de actividad de la enfermedad acompañada de mejoría endoscópica o histológica. Resultados: se alcanzó remisión de la enfermedad en todos los pacientes que recibieron factor de crecimiento epidérmico y en seis de los grupos mesalacina enema y placebo. Todas las comparaciones entre grupos mostraron superioridad estadísticamente significativa para el factor de crecimiento epidérmico, único producto que logró la reducción significativa del índice de actividad de la enfermedad y de la presencia e intensidad de los síntomas digestivos en los pacientes luego del tratamiento. Ningún evento adverso fue reportado. Conclusiones: estos resultados son consistentes con las anteriores evidencias moleculares y clínicas que señalan al factor de crecimiento epidérmico capaz de reducir la actividad e inducir la remisión de la colitis ulcerosa. Debe ser realizado un nuevo estudio en un número mayor de pacientes para confirmar la eficacia de los enemas de factor de crecimiento epidérmico.

    Full Text Available One of the main areas of work in Comparative Politics and Political Theory has been the determination of the variables associated with the stability/instability of political systems in general, and democracy in particular. This paper focuses on one of these variables. One with newly acquired importance after the recent electoral successes by the left, but that nevertheless has not been in the spotlight of scholarly analysis: ideological polarization. Particularly, ideological polarization brought about by the attempt to pursue by the government a leftist political project. The main focus is on the ideological project pursued by the Venezuelan Bolivarian Government and its association with the political instability of 2002 and 2003. The paper considers this topic taken into account mainstream theoretical approaches on political stability, and the experience of previous Latin American leftist governments. The paper reaches the conclusion that in Latin America the attempt to implement a socialist program by a democratically elected government, if it is done without meaningful social and political negotiation, and with authoritarian overtones, is likely to lead to intense political instability and to the ultimate failure of the proposed social change. Los factores vinculados a la estabilidad o inestabilidad de los sistemas políticos y la democracia han sido una preocupación central de la política comparada y la teoría política. Este trabajo se centra en analizar un factor que adquiere nueva importancia dado el resurgimiento de la izquierda en América Latina, pero que no ha estado en el centro del debate académico sobre la estabilidad democrática: la polarización ideológica producida por el adelanto de un proyecto político de izquierda desde el gobierno. Su análisis se enmarca en los enfoques teóricos sobre la estabilidad de la democracia y los sistemas políticos. Dentro del contexto de los gobiernos de izquierda en América Latina, se

    Understanding of the renal venous anatomy and its variations is essential to perform any procedure in the region. We report a variation of the left renal venous tree found during a cadaveric dissection, the retro-aortic left renal vein. It was a unique venous trunk that emerged from the left renal hilum and traveled dorsally to the abdominal aorta before reaching the inferior vena cava. The existence of this vessel is associated to the embryology of the inferior vena cava. We discuss the surg...

    Full Text Available The objectives of this work are to rebuild the Communist and Socialist thinking and the political proposals used, between 1890 and 1945, to set a new model of economics and society within the agrarian sector in the Pampas Region, and which, on its basis, include elements of social and technological utopias. Along the first half of the twentieth century, the left wings developed several projects aimed to transform the agrarian economics and society in Argentina and thus, tried to influence the modifications of social and economics rural relations dominant in the country, and in particular in the Pampas Region. Those proposals started to throw the imaginary of a rural world different to the current upon the speech and the political thinking of the left wings. In many of them shaped as a social utopia and in others shaped as a technological utopia, for its realization.Este trabajo tiene como objetivos reconstruir el pensamiento socialista y comunista y las propuestas políticas con las que buscaron entre 1890 y 1945, concretar un nuevo modelo de sociedad y economía en el agro pampeano y que en sus fundamentos inscribían elementos de las utopías sociales y las tecnológicas. A lo largo de la primera mitad del siglo XX las izquierdas formularon diversos proyectos para la transformación de la economía y la sociedad agrarias argentina, intentando con ellos incidir en la modificación de las relaciones económicas y sociales rurales dominantes en el país y en particular en su región pampeana. Esas propuestas fueron proyectando en el discurso y en el pensamiento político de izquierdas el imaginario de un mundo rural alternativo al vigente, tomando en muchas de ellas la forma de la utopía social y en otras la de la utopía de tipo tecnológico para su realización.

    Ossifying fibromas are bone-related benign neoplasms that are characterized by well-demarcated lesions composed of fibrocellular tissue and mineralized material with varying appearances. Although small lesions are asymptomatic, they may cause enlargement of the affected jaw and rarely require reconstructive or restorative treatments for aesthetic and functional problems. In this study, we report a 35-year-old woman who underwent multidisciplinary treatment for a large ossifying fibroma of the mandible. A segmental mandibular resection was performed, and immediate reconstruction was performed using iliac bone and great auricular nerve grafts. After consolidation of the grafted bone, oral rehabilitation was fulfilled using osseointegrated implants and a fixed prosthesis. There was no evidence of recurrence ten years after the resection of the tumor. The range of mouth opening and motion of the temporomandibular joint provided a functional mandible. The neurosensory examination revealed the recovery of sensibility of the mental region and pulpal sensitivity of the teeth. The prosthesis was stable, and no clinical or radiographic signs of implant failure were observed. Our results demonstrate that the proper combination of reconstructive and restorative treatments could result in appropriate aesthetic and functional outcomes for a period of ten years.

    Full Text Available Abstract (english Analysis of cross-sectional and follow up clinical studies, of hypertensive patients with the different left ventricular geometric patterns, provide plausible explanations for the transition from hypertensive heart disease to the two distinct phenotypes of systolic and diastolic congestive heart failure. According to the LIFE study treated-uncomplicated patients, with normal ventricular geometry (12%, concentric remodeling (11 % and concentric hypertrophy (34 %, may evolve to the eccentric hypertrophy pattern. Patients with the eccentric hypertrophy pattern have selective sympathetic activation and progressive enlargement of the left ventricular cavity with thinning of its walls. This pattern goes on to a stage of systolic dysfunction with diminished ejection fraction and enhanced degradation of the collagen matrix. On the other hand, patients with the concentric hypertrophy pattern have predominant activation of the renin-angiotensin-aldosterone system and progressive shrinking of the left ventricular cavity with thickening of its walls. This pattern usually precedes the stage of diastolic heart failure with preserved ejection fraction, impairment of relaxation and increased deposition of collagen in the myocardial interstitium. Thus, ventricular remodeling preceding diastolic heart failure is opposite to that of hypertensive patients who go on to develop systolic heart failure.

El interés en explorar la narrativa deviene de la creciente importancia de su función testimonial para el análisis de fenómenos sociopolíticos. La literatura, en tanto discurso dotado de múltiples significados, fue durante el periodo estudiado, un arte politizado y un vehículo para la denuncia de asimetrías sociales, capaz de recoger tipos sociales densamente considerados que ilustran la interacción de grupos humanos y el poder político. El artículo pretende aportar a los estudios en torno a las relaciones literatura-política, los cuales en Colombia hoy están ligados a la construcción de la idea de nación, las guerras civiles del siglo XIX, la Violencia de los años 50 del siglo XX y recientemente al narcotráfico.Based on a comparative reading exercise of seventeen Colombian literary works published in the 1970s and 1980s, including novels and short stories, the paper seeks to discuss how was fictionally represented the armed extreme left-wing in the country. The interest in exploring the narrative stems from the growing importance of its testimonial role for the analysis of socio-political phenomena. The Literature, as speech endowed with multiple meanings, was during the period studied a politicized art and a vehicle for the exposure of several social inequalities, capable to gather densely considered social types that illustrate the interaction of human groups and political power. The article seeks to contribute to studies on Literature-Politics relations, which in Colombia today are linked to the construction of the idea of Nation, the Civil Wars of the nineteenth century, the violence of the 50s of the twentieth century and, recently, drug trafficking.

Nuestro objetivo fue realizar un análisis de coste-utilidad de las diferentes opciones de tratamiento en pacientes >40 años con FA concomitante con valvulopatía mitral en España, desde la perspectiva del Sistema Nacional de Salud. Métodos: Se realizó una evaluación económica mediante un modelo de Markov con cuatro estados de salud (ritmo sinusal, FA, ACV dependiente, muerte simulando una cohorte de 1.000 pacientes en cada opción de tratamiento más cirugía de válvula mitral (tratamiento farmacológico, ablación quirúrgica y ablación por catéter. El horizonte temporal fue de 5 años, con ciclos de 3 meses. Los datos de costes y efectos se obtuvieron de la revisión de la literatura y de la opinión de expertos clínicos, descontados al 3,5% anual. Se realizó un análisis de sensibilidad probabilístico para determinar la robustez de nuestros resultados. Resultados: Los años de vida ajustados por calidad (AVAC ganados fueron 3,29, 3,89 y 3,83, respectivamente, para las alternativas de no ablación, ablación quirúrgica y ablación por catéter. Los costes por paciente fueron de 5.770€, 10.034€ y 11.289€, respectivamente. La razón coste/AVAC de ablación quirúrgica frente a no ablación fue de 7.145€. La ablación quirúrgica resultó dominante frente a la ablación por catéter. El análisis probabilístico de sensibilidad mostró que los resultados del modelo fueron robustos. Conclusiones: La ablación quirúrgica es una opción de tratamiento coste-efectiva en los pacientes con FA concomitante, con una razón coste-efectividad por debajo del umbral de eficiencia comúnmente aceptado en España.Objectives: Atrial fibrillation (AF is the most common arrhythmia in clinical practice; this disorder is a risk factor

Resultados: los valores de media para la duración de la onda A del flujo mitral no muestran diferencias significativas; sin embargo, existe un coeficiente de correlación (r y p significativos entre la dispersión de la onda P y la duración de la onda A del flujo mitral para normotensos (r= - 0,117 p=0,05, prehipertensos (r= - 0,309 p=0,001 e hipertensos (r= - 0,586 p=0,001. Existen diferencias significativas entre las medias de dispersión de la onda P entre los grupos de diagnóstico. Conclusiones: se evidencia dependencia de la dispersión de la onda P, del electrocardiograma y de la duración de la onda A del flujo de entrada mitral, hechos que se relacionan con riesgo de fibrilación auricular en el adulto, por lo que quizás este resultado dé un acercamiento a predicciones de riesgo más tempranas en edades pediátricas.Introduction: the relationship between diastolic dysfunction and P wave dispersion in the electrocardiogram is being studied since some

    Full Text Available Com o objetivo de testar o implante de cartilagem auricular heteróloga conservada em glicerina a 98% como alternativa para reparar defeitos na parede torácica em felinos, foram estudados doze animais adultos, sendo distribuídos em dois grupos GI e GII, e avaliados após 60 dias de pós-operatório. Todos os animais foram submetidos à ressecção costal na porção média do tórax abrangendo a 7ª, 8ª e 9ª costelas e posterior implante de cartilagem conchal heteróloga conservada em glicerina a 98%. No GI, foi preservada a musculatura adjacente, já no GII, a musculatura foi retirada. Os animais foram avaliados clinicamente no pós-operatório e, ao final do período, submetidos à eutanásia e necropsia para avaliação macroscópica e microscópica da região do implante. Observou-se proliferação de tecido fibrovascular neovascularizado sobre o implante, com aderência pulmonar e diafragmática em algumas das unidades experimentais. O implante de cartilagem heteróloga conservado em glicerina a 98% pode ser utilizado para reconstrução de parede costal cujo defeito abranja o espaço de parte de três costelas. O implante em 60 dias é substituído por tecido cicatricial, sem apresentar sinais clínicos de rejeição.Twelve adult cats were divided in groups GI and GII with the objective of testing a dog auricular cartilage implant conserved in 98% glycerin as an alternative to repair thoracic wall defects. All animals were submitted to a resection of the medial portion of the thorax by removal of the 7th, 8th and 9th ribs and posterior cartilage implantation. GI had the adjacent musculature preserved and in GII cat's had it removed. The animals were clinically evaluated in the post operative period and after sixty days submitted to euthanasia for microscopic evaluation of the implanted local. Proliferation of granulation tissue and neomorph over the implant was observed in all animals and some had lung and diaphragm adherence. The

    Full Text Available Os defeitos de espessura completa do palato que resultam em comunicação oro-nasal raramente cicatrizam espontaneamente. Eles requerem reparo cirúrgico, porém, pode ser difícil obter cicatrização satisfatória devido às condições próprias das cavidades nasal e oral. Neste experimento, foram utilizados 14 cães, reunidos em dois grupos de igual número. Todos animais foram submetidos à indução de fenda palatina experimental. O grupo G1 foi o controle, cuja palatoplastia foi realizada a partir da confecção de "flap" muco-periósteo. No grupo G2, foi utilizada cartilagem da pina auricular conservada em glicerina a 98% entre o osso palatino e o muco-periósteo. Os animais foram avaliados macroscopicamente quanto ao processo cicatricial, por radiografias para a regeneração óssea e por rinoscopia para observar a regeneração da mucosa nasal. Foi observada a cicatrização da mucosa oral a partir do 10º dia, com deiscência de sutura em dois animais do grupo G1. A radiografia demonstrou evolução na cicatrização óssea, num processo mais acelerado no grupo G2 quando comparado ao grupo G1. A rinoscopia revelou, aos 60 dias, completa regeneração da mucosa nasal em ambos os grupos. Ao final do período de avaliação foi observada macroscopicamente, completa fusão óssea nos animais do grupo G2 e incompleta nos do grupo G1, o que demonstrou a interferência benéfica do implante no processo cicatricial do grupo G2.The incomplete defects of hard palate result in oro-nasal fistula seldom cure themselves in a spontaneous way, due to limited condition in oral and nasal cavity it may be difficult to obtain satisfactory cicatrization, requiring surgery to interfere in the healing process. Fourteen dogs arranged in two groups were submitted to experimental hard palate cleft. The G1 group was the control group, in which palatoplasty was achieved with mucous-periosteum flap. In the G2 group, a preserved at 98% glycerin auricular pinna

Con esta categorización el movimiento ecuménico logró instalar la discusión hacia adentro de un espacio democrático mayor, determinado por la oposición al autoritarismo. Esta dicotomía no es sino la expresión de una oposición categorial más abarcativa, aquella planteada entre profetismo y mesianismo que para nosotros caracteriza a los movimientos sociales de inspiración cristiana en el nuevo escenario que se abre en América Latina luego del periodo signado por las dictaduras de seguridad nacional.

    Maxillofacial prostheses are usually fabricated on the models obtained following the impression procedures. Disadvantages of conventional impression techniques used in production of facial prosthesis are deformation of soft tissues caused by impression material and disturbance of the patient due to. Additionally production of prosthesis by conventional methods takes longer time. Recently, rapid prototyping techniques have been developed for extraoral prosthesis in order to reduce these disadvantages of conventional methods. Rapid prototyping technique has the potential to simplify the procedure and decrease the laboratory work required. It eliminates the need for measurement impression procedures and preparation of wax model to be performed by prosthodontists themselves In the near future this technology will become a standard for fabricating maxillofacial prostheses.

    Half of the malformations in the ear, nose, and throat region affect the ear. Malformations of the external ear (pinna or auricle with external auditory canal [EAC]) are collectively termed microtia. Microtia is a congenital anomaly that ranges in severity from mild structural abnormalities to complete absence of the external ear (anotia). Microtia occurs more frequently in males (∼2 or 3:1), is predominantly unilateral (∼70-90%), and more often involves the right ear (∼60%). The reported prevalence varies geographically from 0.83 to 17.4 per 10,000 births. Microtia may be genetic (with family history, spontaneous mutations) or acquired. Malformations of the external ear can also involve the middle ear and/or inner ear. Microtia may be an isolated birth defect, but associated anomalies or syndromes are described in 20 to 60% of cases, depending on study design. These generally fit within the oculo-auriculo-vertebral spectrum; defects are located most frequently in the facial skeleton, facial soft tissues, heart, and vertebral column, or comprise a syndrome (e.g., Treacher Collins syndrome). Diagnostic investigation of microtia includes clinical examination, audiologic testing, genetic analysis and, especially in higher grade malformations with EAC deformities, computed tomography (CT) or cone-beam CT for the planning of surgery and rehabilitation procedures, including implantation of hearing aids.

    Full Text Available In the official newspaper of the Estado Novo, a dictatorship led by Getúlio Vargas in Brazil from 1937 to 1945, a group of intellectuals organized a cultural section, «Pensamento da América», devoted to publishing translations of writers from across the Americas. Drawing on archival research, this article reconstructs the trajectory of this cultural section, from muted anti-fascism and Latin Americanism, in 1941, to playing a supporting role for Vargas’s wartime foreign policy, from 1942 on. It is concerned, above all, with exploring the contexts that both opened the way and set the limits for the activities of the intellectuals responsible for «Pensamento da América».

    Full Text Available This article analyzes the background and evolution of the affiliation of the Cuban left with the Comintern (Communist International, from their first contacts with the Bolshevik Revolution until the end of the 1920s. The authors recover a little-known history in historiography to show that, despite a series of disagreements between Moscow and Cuban communism, Comintern influence was by no means considered unfavorable to interests for Cuba’s communist movement. In fact, it helped to strengthen the left in that nation.

    Full Text Available La represión y la violencia políticas desatadas por los militares sublevados y sus cómplices civiles, a partir de verano de 1936, no solamente fue un aspecto ya previsto y programado de la insurreción, sino que también se extendió por todo el territorio español y fue adaptado según las características de las diferentes regiones en donde se aplicó. En el caso de Cataluña, la represión franquista, además de aplicarse en sus líneas generales, añadió el plus del «separatismo», la persecución del catalanismo político y cultural en todas sus variantes posibles. De aquí que hiciera fortuna la expresión «rojo-separatista», tanto a nivel propagandístico como de acusación política y criminal, que permitía ensanchar la represión e incluir a un amplio número de víctimas: conservadores, republicanos, comunistas, católicos y librepensadores. A partir del análisis de diferentes expedientes de responsabilidades políticas, puede seguirse la aplicación de la acusación de «rojo-separatista» y la construcción de una imagen muy concreta de los vencidos.The political repression and violence launched by the rebel militaries and their civil accomplices, from the summer of 1936, was an aspect already foreseen and scheduled of the insurrection. Furthermore, this repression and violence was spread in the whole Spanish territory and adapted to the features of the features of the different regions where it was brought. In the case of Catatonía, the Francoist repression, besides of being applied in its general Unes, added a plus of «separatism», the persecution of the political and cultural catalanísm in any of its possible variants. From here it comes the expression «red-separatist» that become popular, both at the propaganda level, and to include in it a larga number of victims: conservatives, republicans, communist, Catholics and freethinkers. The applícation of the charge of «red-separatist» could be foUowed from the analysis of different files of political responsibilities, which set up a very specific image of the ones defeated.

    Full Text Available La última década ha estado marcada por el resurgimiento de movimientos políticos izquierdistas en Latinoamérica. Sin embargo, la magnitud del alzamiento de estas “nuevas izquierdas” oculta a menudo la relación ambivalente entre estos movimientos y la sociedad, así como su lucha por encontrar alternativas al modelo de desarrollo prevaleciente. A lo largo del continente, el sector de las microfinanzas ha llenado el vacío dejado por los fallos de los bancos públicos, desarrollándose bajo una forma crecientemente comercial. Análisis de Nicaragua, Ecuador y Bolivia revelan que los nuevos gobiernos comparten su desconfianza hacia las IMF (instituciones de microfinanzas. Sin embargo, en la ausencia de alternativas viables para la provisión de servicios financieros, los gobiernos y las microfinanzas se ven obligados a coexistir. El medio en el cual lo hacen varía grandemente, dependiendo de políticas locales y factores institucionales. No obstante, algunas tendencias comunes pueden ser discernidas.

    Full Text Available Abstract Background The prevalence of maternal drug use during pregnancy in North America has been estimated to be as high as 6-10%. The consequences for the newborn include increased risk for perinatal mortality and ongoing physical, neurobehavioral, and psychosocial problems. Methadone is frequently used to wean women off street drugs but is implicated as a cause of adverse fetal/neonatal outcomes itself. The purpose of our study was to test the ability of maternal acupuncture treatment among mothers who use illicit drugs to reduce the frequency and severity of withdrawal symptoms among their newborns. Methods We randomly assigned chemically dependent pregnant women at BC Women’s Hospital in Vancouver, British Columbia to daily acupuncture treatments versus usual care. By necessity, neither our participants nor acupuncturists were blinded as to treatment allocation. Our primary outcome was days of neonatal morphine treatment for symptoms of neonatal withdrawal. Secondary neonatal outcomes included admission to a neonatal ICU and transfer to foster care. Results We randomized 50 women to acupuncture and 39 to standard care. When analyzed by randomized groups, we did not find benefit of acupuncture; the average length of treatment with morphine for newborns in the acupuncture group was 2.7 (6.3 compared to 2.8 (7.0 in the control group. Among newborns of women who were compliant with the acupuncture regime, we observed a reduction of 2.1 and 1.5 days in length of treatment for neonatal abstinence syndrome compared to the non-compliant and control groups, respectively. These differences were not statistically significant. Conclusions Acupuncture may be a safe and feasible treatment to assist mothers to reduce their dosage of methadone. Our results should encourage ongoing studies to test the ability of acupuncture to mitigate the severity of neonatal abstinence syndrome among their newborns.

    1992-01-01

    Between April 1990 and July 1991, 10 patients, were fulgurated after right atrial endocardial mapping with the purpose of destroying or modifying the site of origin of atrial flutter. Mean age, 47 years old (23-61), 9 males. All patients suffered "common" atrial flutter episodes with very rapid ventricular response (greater than or equal to 150 beats per minute) refractory to pharmacological therapy. All patients had pathologic potentials with prolonged duration between 90 and 160 ms (m = 109) which preceded other reference electrodes in the high right atrium and His position. Electrical stimulation from that zone provoked the capture entrainment and termination of the flutter; the same configuration of the arrhythmia was obtained with electrical stimulation from the suspected zone. With the catheter in that situation one or two direct current cathodic, unipolar shocks were given with energy of 60-150 Joules (m = 117). In the follow up (16-73 weeks), 8 patients are free of symptoms without drugs, one suffered a new episode after 7 weeks, His fulguration was performed and a permanent pacemaker implanted. The other patient has failed two session and is still on treatment.

    Results: The median age of the patients was 80 (21-91 years. The median percentage of flap survival was 100,00. The median operation duration was 92,00 minutes. Donor site epithelialization was 21 and 20 days in the first two patients, with a median of 20,5 days. In the latter three patients, a silver-containing dressing material was used prophylactically to suppress contamination by skin bacteria, which led to a decrease of the length of healing time to a median of 11,00 days, with a range of 3,00. Conclusion: PCF offers a one-stage procedure and can be used in the reconstruction of defects of the auricle exceeding 2 cm. The use of axial pattern peninsular conchal flap is recommended to all of our colleagues. [Arch Clin Exp Surg 2016; 5(1.000: 1-6

    Full Text Available Neuromodulation, thanks to intrinsic and extrinsic brain feedback loops, seems to be the best way to exploit brain plasticity for therapeutic purposes. In the past years, there has been tremendous advances in the field of non-pharmacological modulation of brain activity. This review of different neurostimulation techniques will focus on sites and mechanisms of both transcutaneous vagus and trigeminal nerve stimulation. These methods are scientifically validated non-invasive bottom-up brain modulation techniques, easily implemented from the outer ear. In the light of this, auricles could transpire to be the most affordable target for non-invasive manipulation of central nervous system functions.

Se le diagnosticó tromboembolismo pulmonar bilateral por tomografía axial computada helicoidal. Se lo anticoaguló con heparina sódica y se le realizó un ecocardiograma transesofágico que mostró un trombo que atravesaba el foramen oval y se alojaba en la aurícula izquierda. No presentaba signos clínicos de embolización sistémica. Se realizó la embolectomía quirúrgica y cierre del defecto auricular. El paciente falleció.An intracardiac thrombus traversing a patent foramen ovale is a very infrequent but potentially catastrophic complication of the thromboembolic disease. It is named "impending paradoxical embolism". We report the case of a 71 year old Caucasian male warded in ten days after a prostatectomy because of bilateral pulmonary embolism. Diagnosis was confirmed by HCT scan and the patient received anticoagulation with heparin. A transesophageal ecocardiogram disclosed a thrombus traversing foramen ovale into the left atrium. Surgical embolectomy was performed, but the patient died shortly after surgery.

Se evaluaron las dificultades técnicas y la morbimortalidad del procedimiento.ResultadosEn todos los pacientes se pudo realizar el abordaje sin dificultades técnicas con una exposición adecuada de la válvula mitral. La tasa de trastornos de conducción en el posoperatorio fue del 9,7% y la necesidad de implante de un marcapasos definitivo fue del 4,8%. De los pacientes que tenían fibrilación auricular previa (n = 18, el 83,3% recuperaron ritmo sinusal o nodal alto en el posoperatorio.ConclusionesEl abordaje transeptal extendido al techo de la aurícula izquierda constituyó una alternativa de acceso a la válvula mitral, con una exposición mejor que el abordaje tradicional, aunque a expensas de una técnica más demandante. Los tiempos quirúrgicos, la mortalidad y las complicaciones fueron similares a los de la técnica convencional, a excepción de una probable incidencia mayor de ritmo nodal y bloqueo A-V.

Analisa as relações entre o Irã e a América Latina, bem como o possível apoio que Ahmadinejad receberia da esquerda e do governo brasileiro. O trabalho associa as relações, os conflitos, as contradições e as perseguições ideológicas entre os grupos de esquerda iranianos e os movernos que sucederam a Revolução Islâmica. Ressalta que há incoerência entre o apoio que Ahmadinejad recebe da esquerda latino-americana e o modo como o presidente lida com a oposição em seu país, sobretudo os próprios partidos de esquerda, que são tratados de forma represiva pelo regime teocrático de Teerã. O texto conclui que há falta de coerência no comportamento do governo iraniano em aprofundar seus laços com os governos de esquerda da América Latina, enquanto implementa, na sua política doméstica, uma repressão implacável contra seus próprios grupos de esquerda.

Notre intérêt est de montrer, par rapport à une tranche de l'élite politique, le double mouvement de continuité de la politique des partis par les dirigéants politique et de la mobilité inter-partis ; ces mouvements sont issus des changements électoraux en cours. En plus, les modalités des carrières politiques du groupe parlementaire et la circulation entre les postes parlementaires et d'autres fonctions de l'État sont également analysés. Le travail s'appuie sur une recherche sur la trajectoire des sénateurs uruguayens de 2005 à 2010 et compare cette période aux législatures antérieures, toujours de la période postérieure à la dictature (1985-2005. Pour la législature actuelle, on utilise la méthode de trajectoires biographiques multiples, et on étudie 38 sénateurs exerçant le mandat dans cette période, en se servant des sources documentaires personnelles, parlementaires et biographies publiées, ainsi que des recherches et des entretiens menés directement auprès des sénateurs. L'étude permet non seulement d'identifier des standards communs chez les parlementaires, mais encore d'exploiter les différences des trajectoires politiques des sénateurs des partis traditionnels et de ceux de la gauche.

    2007-12-01

    Full Text Available This article draws on field theory to explain why leftist parties in Brazil first broached debates on homosexual liberation in the late 1970s and early 1980s. The concept of a cultural field allows one to bring together both an institutional and a cultural analysis of changing debates in the left, casting light on processes of contestation often obscured in the institutionalist party literature. Electoral institutional changes and the emergence of a new generation of cadres, particularly from the student movement, fundamentally changed who and what were representable in the field. The emergence of a youth counterculture also expanded the discursive repertoire available to activists and their party allies, supported by debates in Marxist circles occurring internationally. This conjuncture of forces ultimately allowed party militants to contest meanings historically attached to the body, sexuality, the political, and everyday life.

    Full Text Available Validity of the ideological left/right continuum during 2011 Presidential Elections in Lima-PeruThis study analyzes the relationship between political ideology, voting behavior and emotional responses after Peruvian presidential elections in 2011. Scales of intolerance for ambiguity, need for closure, right-wing authoritarianism (RWA and the right-wing political orientation were used to assess right-wing political conservatism. A structural equation model proposes that intolerance of ambiguity and need for closure exert a direct effect on RWA. Also, RWA influences directly the right-wing political orientation, which exerts a direct influence on negative emotional responses and an inverse effect on positive emotional responses after O. Humala’s victory. Final discussion focuses on the contemporary relevance of left/right ideological continuum.

La cardiología intervencionista vuelve a estudiar la morfología macroscópica y las características estructurales del corazón. En suma, una onda nueva ha nacido para revisitar la anatomía cardíaca dado que la información de que disponíamos hasta el momento era incompleta o llanamente errónea. Como resultado de este interés, recientes estudios han revelado las características anatómicas, aspectos arquitectónicos y detalles histológicos de ciertos componentes del corazón que son de interés para el entendimiento del sustrato de las arritmias y su ablación. El propósito de este estudio ha sido revisar detalles de la morfología cardíaca tales como el istmo inferior o istmo cavotricuspídeo, la región sinoatrial y la cresta terminal, el triángulo de Koch y su contenido, los orificios de las venas pulmonares y su vecindad con la aurícula izquierda, la arquitectura de la unión venoatrial y de la pared auricular posterior. En resumen, describimos la anatomía y arquitectura de la orejuela izquierda y de la cresta lateral izquierda, la vena de Marshall y el seno coronario, así como la inervación autónoma de las aurículas y su relación con el esófago y los nervios frénicos. Finalmente, estudiamos las características anatómicas de los ventrículos derecho e izquierdo.

    A novel approach to the diagnosis of bone available for craniofacial implant positioning is discussed in a case that required ear ablation for tumor removal. A mirrored volume of the healthy ear was rapidly prototyped for a clinical trial in an appropriate position relative to the patient's face. Three ideal positions for the implant were chosen in the inner of the volume of the mirrored ear. The same positions were transferred to a diagnostic template that was rapidly prototyped with a positioning arm extending to the zygomatic arch. Computed tomography (CT) revealed errors in the planning of the implant position and, as a clinical consequence, an implant site was excluded from surgical planning. A virtual elaboration for maxillofacial implant positioning was used to define the correct implant site in relation to the available bone, and two craniofacial implants were correctly positioned in the temporal bone.

    Peroxisome proliferator-activated receptors (PPARs), key transcriptional regulators of lipid and energy metabolism in cardiomyocytes, have recently been proposed to modulate cardiovascular pathophysiological responses in experimental models. However, there is little information about the functional activity of PPARs in human heart failure. To investigate PPAR-alpha and -gamma expression and activity, and the association with ET-1 production and fibrosis, in cardiac biopsies from patients with end-stage heart failure due to ischemic cardiomyopathy (ICM) in comparison and from non-failing donor hearts. All samples were obtained during cardiac transplantation. Morphological analysis (by Masson trichrome and image analysis) did not detect fibrosis in the left atrium from non-failing donors (NFLA) or from ICM patients (FLA). However, left ventricles from failing hearts (FLV) contained a greater number of fibrotic areas (NFLA: 3.21+/-1.15, FLA: 1.63+/-0.83, FLV: 14.5+/-3.45%; n = 9, PPPAP-gamma mRNA (by RT-PCR) and protein (by Western blot) levels were higher in the ventricles from failing hearts compared with the atrium from failing and non-failing hearts. Electrophoretic mobility shift assays showed that PPAR-alpha and PPAP-gamma were not activated in the ventricles (NFLA: 1.00+/-0.11, FLA: 1.89+/-0.24, FLV: 0.95+/-0.07; n = 9, PPPAP-gamma are selectively activated in the atria from ICM patients and might be functionally important in the maintenance of atrial morphology.

    Full Text Available Elizabeth B Stuyt,1 Claudia A Voyles2 1Department of Psychiatry, University of Colorado Health Sciences Center, Pueblo, CO, 2Department of Clinical Studies, AOMA Graduate School of Integrative Medicine, Austin, TX, USA Abstract: The National Acupuncture Detoxification Association (NADA-standardized 3- to 5-point ear acupuncture protocol, born of a community-minded response to turbulent times not unlike today, has evolved into the most widely implemented acupuncture-assisted protocol, not only for substance abuse, but also for broad behavioral health applications. This evolution happened despite inconsistent research support. This review highlights the history of the protocol and the research that followed its development. Promising, early randomized-controlled trials were followed by a mixed field of positive and negative studies that may serve as a whole to prove that NADA, despite its apparent simplicity, is neither a reductive nor an independent treatment, and the need to refine the research approaches. Particularly focusing on the last decade and its array of trials that elucidate aspects of NADA application and effects, the authors recommend that, going forward, research continues to explore the comparison of the NADA protocol added to accepted treatments to those treatments alone, recognizing that it is not a stand-alone procedure but a psychosocial intervention that affects the whole person and can augment outcomes from other treatment modalities.

    2013-05-01

    Full Text Available Background  To construct a sophisticated three-dimensionalframework, numerousmodifications have been reported in the literature. However, mostsurgeons have paid little attentionto the anatomical configuration of the concha and more to its deepness and hollowness,leading to unsatisfactory outcomes.Methods  For a configuration ofthe concha thatis definitely anatomical,the authorfurtherdeveloped and employed the conchal bowl element,which has been used by severalsurgeonsalthough the results have not been published elsewhere. The author constructed the conchalbowl element in one of three patterns according to the amount of available cartilages: oneblock,two-pieces, or a cymba bowl element only. A total of 20 patients underwent auricularreconstruction using a costal cartilage framework between 2009 and 2012. The 8 earliestreconstructionswere performedwithout a conchal bowl element and the latter 12with a conchalbowl element. The patientswere followed up for more than 1 year. The aesthetic resultswerescored by evaluating characteristicsinvolving the stability ofthe crus helicis,the conchal definition, and the smoothness ofthe helical curve.Results  The earsreconstructed earlywithout a conchal bowl elementshowed a shallowandone or two incompletely separated concha with an obliterated cymba conchal space. Theyalso did not have a realistic orsmooth curve ofthe helix because of an unstable crus helicis.However, earsreconstructed laterwith the concha bowl elementshowed a definite crus helicis,deep cymba conchalspace, and smooth helical curve.Conclusions  The construction of the conchal bowl element is simple, not time-consumingprocedure. It is suggested that the conchal bowl element must be constructed and attachedto themain framework for natural configuration ofthe reconstructed ear.

    Full Text Available El Cor Triatriatum izquierdo es una anomalía congénita cardiaca rara. Es infrecuente que estos pacientes sobrepasen la edad de 40 años sin su corrección quirúrgica. El objetivo de este artículo fue el de presentar un paciente de 43 años que fue intervenido quirúrgicamente a la edad de 5 años para el cierre de una comunicación interauricular y donde el diagnóstico de esta entidad no se realizó. Un mes antes del ingreso comienza con palpitaciones y disnea a los moderados esfuerzos. Con la ecografía transesofágica se hace el diagnóstico de esta anomalía, la cual se asociaba a una insuficiencia mitral y fibrilación auricular. Se procedió a la resección de la membrana fibromuscular y la reparación de dos hendiduras congénitas en el borde del velo anterior de la válvula mitral con buenos resultados. Un año después el paciente se encuentra asintomático y en la ecocardiografía transtoráxica se muestra una aurícula izquierda unicameral con una regurgitación mitral trivial.

    Full Text Available Introduction: The morbidity and mortality of stroke is higher in the cardioembolic etiology, caused mainly atrial fibrillation (AF, arrhythmia characterized by the increase in the elderly population, which together with the greater longevity of women, ranks as ad hoc risk. The aim is to confirm and characterize the major gender differences in this subtype. Methods: Observational, descriptive. Study population: patients admitted with a diagnosis of secondary cardio embolic ictus (CEI to AF at the University Hospital Virgen de la Arrixaca. Sample: 210 patients. Variables: sex, age, AF known/unknown, survival; disability and neurological deficit at high risk factors (RF. Source: Database of the Neurology. Statistical analysis: descriptive. Results: 210 patients (mean age, 77, 38± 58 years; 59% female were included. The average age of women (78, 49± 68 years was significantly higher (p>0, 05 than men (75, 78±1, 01 years. 36, 3% of women and 36,0% of men had unknown AF. One fame Mortality (11, 3% was observed compared to men (7%; moderate physical disabilities and moderate neurological deficit at discharge, with no significant differences between men and women. The main RF was arterial hypertension (76, 7% with a predominance between the women (79, 0% vs. 73, and 3% male. Conclusions: The CEI secondary to AF is more frequent and is the cause of a higher mortality amongst women relative to their higher age. The control of arrhythmia is deficient both in women and in men. There is a high risk of CEI for patients with AF in coexistence with arterial hypertension, this being higher in women.

    2009-12-01

    Full Text Available The intracavitary cardiac tumors have a special place in cardiac surgery due to their peculiar characteristics. Some of them are considered surgical emergencies. The resection must not be delayed because 8 to 10 percent of the affected patients can die, while waiting for surgery, as a result of an intracardiac obstruction of the blood flow. In everyday practice it is not common that patients with cardiac tumors undergo surgery just a few hours after the confirmation of the diagnosis by means of echocardiographic studies. The case of a patient, who had a diagnosis of a large pedunculated left atrial myxoma, with incursion into the left ventricle during diastole, and underwent an emergency surgery due to the threat of fragmentation and embolization resulting from the morphologic characteristics of the tumor, is presented in this article.

    2012-04-01

    Los aneurismas del seno de Valsalva tienen una prevalencia estimada de 0,14%, siendo más comunes en la población masculina. Su localización más frecuente es el seno coronario derecho (70–90%, seguido de seno no coronariano (10–20%, y raramente de seno coronariano izquierdo. Aunque frecuentemente se presentan con defectos congénitos, su asociación con comunicación interauricular es baja. Evolucionan hacia la dilatación progresiva que puede llevar a rotura hacia pericardio o bien fistulizar a cavidades cardíacas. Un diagnóstico e intervención quirúrgica precoz son fundamentales, con una tasa de mortalidad posquirúrgica baja a corto y largo plazo.

    To observe the effect of transcutaneous otopoint electrostimulation (TCOES) on behavior and expression of hippocampal interleukin-1 β (IL-1 β) and tumor necrosis factor-α (TNF-α) expression in lithium-pilocarpine induced chronic spontaneous temporal lobe epilepsy (TLE) rats, so as to investigate its antiepileptic mechanism. Thirty-six SD rats were randomly divided into control, model and TCOES groups ( n =12 in each group). The epilepsy model was established by intraperitoneal injection of lithium chloride (127.2 mg/kg), scopolamine(1 mg/kg, 20 h after the 1 st injection) and pilocarpine (10 mg/kg, 30 min after scopolamine injection). Rats of the control group were treated by injection of normal saline(i.p.i.). Transcutaneous electrostimulation (1 mA, 20 Hz) was applied to bilateral otopoints "Heart" "Lung" and "Subcortex" for 20 min, once daily for 6 weeks except the weekends. The behavior reactions were observed by a video monitoring system. The expression of IL-1 β and TNF-α proteins and genes in the hippocampus were determined by immunofluorescence and quantitative real-time PCR, separately. Behavioral observation showed that after TCOES intervention, the frequency of epilepsy attack was significantly decreased in comparison with pre-treatment ( P epilepsy rats, which may be related to its effects in down-regulating expression of proinflammatory cytokine IL-1 β and TNF-α in the hippocampus.

    1998-01-01

    The normal external ears of 128 Japanese individuals (64 men and 64 women) were measured using the angle-measuring function of analytic software for computerized tomography (CT). The initial baseline for measurement was the orbitomeatal line (OM line); second measurements were taken 1 cm above the baseline (OM+1 cm), and third measurements 2 cm above the baseline (OM+2 cm). The sample was divided into two groups by sex (64 men and 64 women) and into three groups by age (20-39, 40-59, and 60+), and protrusion measurements for the three sections were compared by both sex and age. The results showed that males have larger auricular values (auricular concha cranial angle, auricular concha scaphoid angle, auricular cranial angle) than do females. In terms of age, the results showed that the auricular concha cranial angle becomes larger with increasing age, while the auricular concha scaphoid angle and auricular cranial angle become smaller with age.

    Full Text Available OBJECTIVE: A retrospective analysis of clinical and radiological data was conducted, with an emphasis on perioperative complications and risk factors and a minimum follow-up period of two years. The postoperative quality of life was assessed using the SRS-22 questionnaire. METHODS: Between 1999 and 2009, 25 patients (nine male, 16 female with LCTS, with a mean age of 13.7 years (2.3-29.8 years, were treated with correction and instrumented fusion at a single institution. Seven patients had congenital scoliosis and 18 patients had noncongenital scoliosis (idiopathic, n = 5; neuropathic, n = 4; neoplasm-associated/iatrogenic, n = 3; secondary to other conditions, n = 6. The average preoperative Cobb angle was 74° (49-102°. RESULTS: A mean correction of 51% was achieved postoperatively. The mean Cobb angle at the final follow-up examination was 45° (19-85°, with a significant loss of correction of 8.8° on average. Major complications affected five patients (20%: respiratory insufficiency requiring prolonged intubation, intraoperative cardiac arrest with resuscitation being necessary twice in one patient, persistent clonus, low-grade infection, implant-based complications requiring revision surgery, and adding-on. Minor complications were observed in 22 patients (88%, mainly gastrointestinal and pulmonary. No cases of paraplegia or death occurred. A noncongenital etiology had been diagnosed before the age of 10 years in all of the patients who had major complications. The best score on the SRS-22 questionnaire was achieved in the domain of pain (87%, while the poorest was in the domain of self-image (68%. CONCLUSIONS: The results of this study emphasize an increased complication rate in patients with LCTS scheduled for scoliosis surgery. Additional preoperative examinations (MRI, paediatric consultation, cardiologic consultation, pulmonary function test are mandatory in patients with LCTS. Preoperatively, patients should be informed about the increased cardiopulmonary and neurological risk which may be associated with scoliosis surgery.OBJETIVO: Fue realizado un análisis retrospectivo de datos clínicos y radiológicos, con énfasis en complicaciones perioperatorias y factores de riesgos, y un período mínimo de seguimiento de 2 años. La calidad de vida posoperatoria fue evaluada usándose el cuestionario SRS-22. MÉTODOS: entre 1999 y 2009, 25 pacientes (nueve del sexo masculino, 16 del sexo femenino con ETCI, con edad promedio de 13,7 años (2,3 - 29,8 años fueron tratados con corrección y fusión instrumentada, en una única institución. Siete pacientes tenían escoliosis congénita y 18 pacientes tenían escoliosis no congénita (idiopática, n = 5; neuropática, n = 4; asociada a neoplasma/iatrogénica, n = 3; secundaria de otras condiciones, n = 6. El ángulo de Cobb preoperativo promedio fue 74º (49-102º. RESULTADOS: una corrección promedio de 51% fue alcanzada después de la operación. El ángulo de Cobb promedio, en el examen final de seguimiento, fue 45º (19-85º, con una pérdida significativa de corrección de 8,8º en promedio. Complicaciones graves afectaron a cinco pacientes (20%: insuficiencia respiratoria que requirió intubación prolongada, paro cardíaco intraoperativo con resucitación siendo necesaria dos veces para un paciente, clonus persistente, infección leve, complicaciones con implantes que precisaron de otra cirugía, y accesorios. Complicaciones de menor importancia fueron observadas en 22 pacientes (88%, principalmente gastrointestinales y pulmonares. No ocurrieron casos de paraplejía ni de muerte. Una etiología no congénita fue diagnosticada, antes de la edad de 10 años, en todos los pacientes que tuvieron complicaciones graves. La mejor puntuación en el cuestionario SRS-22 fue obtenida en el dominio de dolor (87%, mientras que la peor se registró en el dominio de la autoimagen (68%. CONCLUSIONES: Los resultados de este estudio enfatizan una tasa de complicación aumentada en pacientes portadores de ETCI con programación de cirugía de escoliosis. Exámenes preoperatorios adicionales (IRM, consulta pediátrica, consulta cardiológica, prueba de función pulmonar son obligatorios en pacientes con ETCI. Antes de la operación, los pacientes deben ser informados sobre los mayores riesgos cardiopulmonar y neurológico que pueden estar vinculados a la cirugía de escoliosis.OBJETIVO: Foi realizado estudo retrospectivo baseado em parâmetros clínicos e radiológicos, com ênfase nas complicações, fatores de risco e seguimento mínimo de dois anos. A qualidade de vida pós-operatória foi avaliada por meio do questionário SRS-22. MÉTODOS: No período de 1999 a 2009, 25 pacientes (nove do sexo masculino e 16 do sexo feminino com idade variando de 2,3 a 29,8 anos (média de idade de 13,7 anos foram submetidos a tratamento cirúrgico por meio de instrumentação e artrodese. Sete pacientes apresentavam escoliose congenital, cinco apresentavam escoliose idiopática, quatro neuropática, três associada à neoplasia ou iatrogenia, e seis associada a outras doenças. A média dos valores pré-operatórios do ângulo de Cobb foi 74° (49-102°. RESULTADOS: A média de correção no pós-operatório foi de 51%. Na avaliação de seguimento final, o valor médio do ângulo de Cobb foi 45° com variação de 19 a 85°, tendo ocorrido significante perda da correção com o valor médio de 8.8°. Complicações maiores ocorreram em cinco pacientes (20%: insuficiência respiratória requerendo entubação prolongada, parada cardíaca intraoperatória com ressuscitação, clônus persistente, infecção de baixo grau, complicações com implantes requerendo revisão cirúrgica, e descompensação do tronco. Complicações menores foram observadas em 22 pacientes (88%, sendo principalmente gastrointestinais e pulmonares. Nenhum caso de paraplegia ou morte ocorreu na série de pacientes estudados. As curvas de etiologia não congênita foram diagnosticadas antes dos 10 anos de idade em todos os pacientes que apresentaram complicações maiores. O melhor escore do questionário SRS-22 foi observado no domínio da dor (87%, e o pior no domínio da autoimagem (68%. CONCLUSÕES: O resultado do estudo enfatiza as altas taxas de complicação nos pacientes portadores de escoliose torácica sinistro-convexa que são submetidos ao tratamento cirúrgico. Avaliações pré-operatórias adicionais (RNM, avaliação pediátrica, avaliação cardiológica, teste de função pulmonar devem ser realizadas nesse grupo de pacientes. Antes do procedimento, os pacientes devem ser informados acerca do alto risco de complicações cardiopulmonares e neurológicas associadas ao tratamento cirúrgico da deformidade.

    Full Text Available La falla cardiaca está relacionada con anormalidades en la contracción y relajación ventricular. Estudios recientes han mostrado que en la mayoría de los pacientes con insuficiencia cardiaca coexisten alteraciones de la función sistólica y diastólica, y en algunos casos la función sistólica es normal pero la falla cardiaca es generada por disfunción ventricular diastólica. El índice de performance miocárdico (tiempo de contracción isovolumétrica sumado al tiempo de eyección ventricular dividido el tiempo de eyección, “Índice de Tei” ha sido descrito como una manera más efectiva para el análisis de la Disfunción Miocárdica Global que otros parámetros de función sistólica y diastólica. Con base en estos antecedentes, los autores determinaron el valor normal del índice de Tei para el ventrículo izquierdo en caninos sanos en la ciudad de Bogotá (2.600 msnm con el objeto de utilizar dicho valor como índice de la función sistodiastólica. Se obtuvo un valor medio de 0,33 con un desvío estándar de 0,10. Asimismo pudo verificarse que no existe correlación con la frecuencia cardiaca, peso corporal ni con la fracción de eyección ventricular izquierdo (P<0,05.

    Full Text Available Resumen La mayor prevalencia de fibrilación auricular se duplica en pacientes con cardiopatía hipertensiva. En el estudio Framingham se encontraron como factores de riesgo: la hipertensión, la máxima duración y dispersión de la onda P del electrocardiograma, el tamaño de la aurícula y la masa ventricular izquierda. El sistema renina-angiotensina-aldosterona es responsable de la inflamación y los cambios estructurales que justifican la aparición de arritmias en el paciente hipertenso. La presencia de arritmias ventriculares, desde complejos ventriculares prematuros hasta la taquicardia ventricular, se ha demostrado entre un 10 - 27 % en los pacientes afectados, porcentaje que disminuye mientras más grave es la arritmia. Se han resumido los siguientes marcadores incruentos de riesgo para presentar arritmias ventriculares: dispersión y variabilidad del intervalo QT, presencia de potenciales tardíos, variabilidad de la frecuencia cardíaca, y morfología anormal y alternancia de la onda T. Todos ellos relacionados con cambios anátomo-estructurales de la pared ventricular, que afectan el potencial de acción. La importancia de conocer la epidemiología, fisiopatología, y los marcadores incruentos de riesgo de presentar arritmias en el paciente hipertenso, ofrece un camino para la aplicación de una correcta terapéutica en el control de las cifras de presión arterial y regresión de la hipertrofia, como lo han demostrado los fármacos inhibidores del sistema renina-angiotensina-aldosterona, que disminuyen el riesgo de arritmias. / Abstract The higher prevalence of atrial fibrillation is doubled in patients with hypertensive heart disease.

This study has investigated the effect of atorvastatin on the progression of cardiac remodelling and ACE- 2 expression in diabetic myocardium in rats. Materials and Methods. Diabetes was induced in Holtzman rats with an intraperitoneal injection of streptozotocin. The animals were divided into 3 groups: (1 normal control rats, (2 diabetic rats and (3 diabetic rats treated orally with atorvastatin (50 mg/kg/day. After eight weeks of treatment, the hearts were removed for morphometric studies, collagen content assay and genetic expressions of ACE and ACE2 mRNA. Results. Myocardial hypertrophy index and collagen deposition were increased in diabetic rats, but not in the treated-diabetic rats, without producing changes in cholesterol levels. Myocardial ACE mRNA levels were increased while ACE2 mRNA levels were decreased in diabetic rats. Atorvastatin administration attenuated overexpression of ACE mRNA and overexpression of ACE-2 mRNA in diabetic rats. Conclusions. Our results indicate that atorvastatin, independently of its cholesterol-lowering capacity, lowers the ACE/ACE2 ratio to normal values and attenuates the development of adverse remodeling in the diabetic heart.

    Alar base retraction is a common yet difficult problem faced by the rhinoplasty surgeon. It may be caused by weakened, overresected lateral crura, vestibular lining deficiencies, or congenital alar malpositioning. Methods of correction include soft tissue manipulation, auricular composite grafting, and cartilage grafting. We present the senior author's graded approach to alar retraction using auricular composite grafting, alar rim grafting, and lateral crural strut graft placement with caudal lateral crural repositioning.

  5. Temple and Postauricular Dissection in Face and Neck Lift Surgery

    Directory of Open Access Journals (Sweden)

    Joo Heon Lee

    2017-07-01

    Full Text Available Periauricular paresthesia may afflict patients for a significant amount of time after facelift surgery. When performing face and neck lift surgery, temple and posterior auricular flap dissection is undertaken directly over the auriculotemporal, great auricular, and lesser occipital nerve territory, leading to potential damage to the nerve. The auriculotemporal nerve remains under the thin outer superficial fascia just below the subfollicular level in the prehelical area. To prevent damage to the auriculotemporal nerve and to protect the temporal hair follicle, the dissection plane should be kept just above the thin fascia covering the auriculotemporal nerve. Around the McKinney point, the adipose tissue covering the deep fascia is apt to be elevated from the deep fascia due to its denser fascial relationship with the skin, which leaves the great auricular nerve open to exposure. In order to prevent damage to the posterior branches of the great auricular nerve, the skin flap at the posterior auricular sulcus should be elevated above the auricularis posterior muscle. Fixating the superficial muscular aponeurotic system flap deeper and higher to the tympano-parotid fascia is recommended in order to avoid compromising the lobular branch of the great auricular nerve. The lesser occipital nerve (C2, C3 travels superficially at a proximal and variable level that makes it vulnerable to compromise in the mastoid dissection. Leaving the adipose tissue at the level of the deep fascia puts the branches of the great auricular nerve and lesser occipital nerve at less risk, and has been confirmed not to compromise either tissue perfusion or hair follicles.

  6. Color ornaments and territory position in king penguins.

    2015-10-01

    King penguins exhibit mutual color ornamentation of feathers and beak color. They breed in dense colonies and produce a single chick every 2 years. Thus, males and females must choose partners carefully to be reproductively successful, and auricular patches of males and UV coloration of beak spots have been shown to influence mate choice. Position in the breeding colony is also important to reproductive success, with pairs on the edge of the colony less successful than those in the center. We studied the mutual ornaments, individual condition, and position of pairs in their breeding colony. Males were significantly larger than females in size, body mass, and auricular patch size. Within pairs, auricular patch size of males and females were significantly correlated, and male auricular patch size and body mass were significantly associated, suggesting a link between this ornament and male body condition. Moving from the edge to the center of the colony, pairs had larger yellow-orange auricular patches, indicating a link between this ornament and settlement in higher quality territories in the center of the colony. Pairs were also less brightly brown colored on the breast and less saturated in UV color of the beak spot. Since we observed pairs that were settling for egg laying, location in the colony may have reflected aspects of pair condition, rather than later jockeying for positioning using ornaments as signals of behavioral dominance.

    Full Text Available Objetivos: Analizar la utilización de una u otra pierna como pierna de ataque predominante en atletas de 400 m vallas de alto nivel. Método: El estudio es descriptivo de corte transversal. Se estudiaron todas las carreras de 400 m vallas de los 72 participantes (34 hombres y 38 mujeres en los XIII Campeonatos del Mundo de Atletismo Daegu 2011, mediante la grabación en video desde la tribuna principal del Daegu Stadium de las 18 carreras de 400 m vallas disputadas, y el posterior análisis mediante la aplicación informática Kinovea 0.8.4. Resultados: Por atletas, en el total de las carreras masculinas, la pierna de ataque predominante fue la izquierda con un 63,6 % (42 atletas y con la pierna derecha hubo un 34,8 % (23 atletas. Solo en un caso había un equilibrio entre izquierda y derecha. En la final hubo un 75 % (6 atletas cuya pierna predominante de ataque fue la izquierda. En cuanto a las mujeres, la pierna de ataque predominante fue la izquierda con un 48,6 % seguida de la pierna derecha con un 41,4 % y para el 10 % había un equilibrio de las dos. En la final, en cambio, la pierna predominante de ataque fue la derecha con un 87,5 % (7 atletas por un 12,5 % de la izquierda (1 sola atleta. Se encontraron diferencias significativas (p = 0,018 en la media de tiempo final de los atletas masculinos según cual fuera su pierna de ataque. Conclusiones: La mayoría de los atletas atacan las vallas con derecha e izquierda en algún momento de la carrera, lo que obliga al dominio técnico bilateral. La pierna de ataque más utilizada es la izquierda, aunque en menor medida en el caso de las mujeres. Por primera vez en una gran competición, 7 de las 8 finalistas tienen la pierna derecha como pierna predominante.

    Full Text Available La aplicación del tándem categorial izquierda-derecha al universo político posee como tal una serie de demandas y condiciones que frecuentemente se pasan por alto. Estas vienen dadas por el analogado principal de estos conceptos, que es el de las distinciones corporales-espaciales. Pero además, es preciso advertir que en la dinámica que lleva a los conceptos políticos desde la autoiluminación (Voegelin propia de los actores políticos a su formalización apta para el análisis teórico, izquierda y derecha siguen itinerarios muy diversos. Eso explica la usual resistencia de los agentes políticos de derecha a ser clasificados según esa categoría y también la inestabilidad/indefinición propia de ese término, sobre todo si se lo compara con su opuesto, la izquierda. En nuestro país, izquierda y derecha como identidades políticas poseen un surgimiento tardío, delimitado a procesos y actores políticos sustancialmente diversos a aquellos que en los países del continente europeo les dieron luz. Una particularidad local es que no se aparecen como clasificaciones propias de las facciones internas de órganos deliberativos sino por fuera de ellos. Nuestra hipótesis es que la más cercana configuración de un modelo de izquierda y derecha en la Argentina tuvo lugar como diferenciación de las diversas líneas internas del peronismo, con posterioridad al cierre de su período clásico (1946-1955.

Se insertaron sondas Nelaton a través de las arterias coronarias y se les inyectó solución de látex y tinta china. Se determinó el diámetro y el punto de origen para la coronaria derecha, coronaria izquierda, interventricular paraconal y circunfleja. Se cuantificaron el número de ramas diagonales, marginales ventriculares izquierdas y postero laterales. Se determinó frecuencia de ramus intermedius y tipo de dominancia. Se realizó análisis estadístico con un error estándar del 5%, con el Epidat 3,1. Resultados: El 100% de los orígenes anatómicos de las arterias coronarias fueron normales. La dominancia mas frecuente fue la derecha, 73%. El promedio de número de ramas marginales izquierdas, diagonales y posterolaterales fue de 3. La frecuencia de ramus intermedius fue de 12%. El calculo de chi cuadrado de Pearson mostró significancia entre el ramus intermedius y número de ramas marginales izquierdas (p=0,0009. Conclusiones: Las características anatómicas de las arterias coronarias del cerdo son similares a las del humano. El ramus intermedius se comporta como una primera rama marginal izquierda y no como una primera rama diagonal como lo afirman algunos autores.

    To quantitatively measure the morphology parameters of the right auricle with 256-slice multidetector computed tomography angiography (MDCTA) in healthy people. A retrospective analysis of 200 patients who had undergone coronary MDCTA with negative findings was performed. The raw imaging data were reconstructed and the right auricular volume, right atrial volume, right auricle height, base long and short axes, base perimeter and area, normal angle, and distance were quantitatively measured. Men had significantly (P right auricular volume (13.3 ± 4.0 vs. 11.7 ± 3.7 mL) and height (33.0 ± 5.0 vs. 30.5 ± 5.2 mm), the base long axis (34.4 ± 4.1 vs. 33.2 ± 3.9 mm), area (787.6 ± 177.6 vs. 771.0 ± 143.2 mm 2 ) and perimeter (119.2 ± 17.5 vs. 115.0 ± 13.0), and the normal distance (22.4 ± 6.6 vs. 20.2 ± 6.7 mm). The normal 95 % reference range for the right auricular parameters was put forward. The right auricular parameters had a good correlation with the right atrium volume, aortic diameter, the body weight, height, and body surface area but a bad correlation with the vertebral body height. Significantly (P  0.05) difference existed in the other right auricular parameters. Quantitative measurements of the right auricle can help us get a good understanding of the right auricular morphology and its relationship with surrounding structures and are helpful for cardiac interventions of electrophysiology and radiofrequency ablation.

  1. Modelling and Simulating the Adhesion and Detachment of Chondrocytes in Shear Flow

    Science.gov (United States)

    Hao, Jian; Pan, Tsorng-Whay; Rosenstrauch, Doreen

    Chondrocytes are typically studied in the environment where they normally reside such as the joints in hips, intervertebral disks or the ear. For example, in [SKE+99], the effect of seeding duration on the strength of chondrocyte adhesion to articulate cartilage has been studied in shear flow chamber since such adhesion may play an important role in the repair of articular defects by maintaining cells in positions where their biosynthetic products can contribute to the repair process. However, in this investigation, we focus mainly on the use of auricular chondrocytes in cardiovascular implants. They are abundant, easily and efficiently harvested by a minimally invasive technique. Auricular chondrocytes have ability to produce collagen type-II and other important extracellular matrix constituents; this allows them to adhere strongly to the artificial surfaces. They can be genetically engineered to act like endothelial cells so that the biocompatibility of cardiovascular prothesis can be improved. Actually in [SBBR+02], genetically engineered auricular chondrocytes can be used to line blood-contacting luminal surfaces of left ventricular assist device (LVAD) and a chondrocyte-lined LVAD has been planted into the tissue-donor calf and the results in vivo have proved the feasibility of using autologous auricular chondrocytes to improve the biocompatibility of the blood-biomaterial interface in LVADs and cardiovascular prothesis. Therefore, cultured chondrocytes may offer a more efficient and less invasive means of covering artificial surface with a viable and adherent cell layer.

    Full Text Available The purpose of this study was to evaluate the effectiveness of Acupuncture-point stimulation (APS in postoperative pain control compared with sham/placebo acupuncture or standard treatments (usual care or no treatment. Only randomized controlled trials (RCTs were included. Meta-analysis results indicated that APS interventions improved VAS scores significantly and also reduced total morphine consumption. No serious APS-related adverse effects (AEs were reported. There is Level I evidence for the effectiveness of body points plaster therapy and Level II evidence for body points electroacupuncture (EA, body points acupressure, body points APS for abdominal surgery patients, auricular points seed embedding, manual auricular acupuncture, and auricular EA. We obtained Level III evidence for body points APS in patients who underwent cardiac surgery and cesarean section and for auricular-point stimulation in patients who underwent abdominal surgery. There is insufficient evidence to conclude that APS is an effective postoperative pain therapy in surgical patients, although the evidence does support the conclusion that APS can reduce analgesic requirements without AEs. The best level of evidence was not adequate in most subgroups. Some limitations of this study may have affected the results, possibly leading to an overestimation of APS effects.

    In 1731, Spanish sailors boarded the British brig Rebecca off the coast of Cuba and sliced off the left ear of its captain, Robert Jenkins. This traumatic auriculectomy was used as a pretext by the British to declare war on Spain in 1739, a conflict that is now known as the War of Jenkins' Ear. Here, we examine the techniques available for auricular repair at the time of Jenkins' injury and relate them to the historical events surrounding the incident. Review of relevant original published manuscripts and monographs. Surgeons in the mid-18th century did not have experience with repair of traumatic total auriculectomies. Some contemporary surgeons favored auricular prostheses over surgical treatment. METHODS for the reconstruction of partial defects were available, and most authors advocated a local post-auricular flap instead of a free tissue transfer. Techniques for repair of defects of the auricle lagged behind those for repair of the nose. Limitations in care of traumatic auricular defects may have intensified the significance of Jenkins' injury and helped lead to the War of Jenkins' Ear, but conflict between Britain and Spain was probably unavoidable because of their conflicting commercial interests in the Caribbean.

    Full Text Available Se realizó una investigación de innovación tecnológica, de corte transversal, con el objetivo de verificar que en los pacientes de ortodoncia se puede prescindir de la radiografía de la mano izquierda en la evaluación del potencial de crecimiento, para lo cual se estudió una muestra de 150 pacientes entre 8 y 16 años, que ingresaron en la Clínica de Ortodoncia de la Facultad de Estomatología de La Habana, entre los años 2004 y 2006. A cada paciente se le realizó una radiografía de la mano izquierda, donde se determinaron los estadios de maduración esquelética a través del método de Grave y Brown y una radiografía panóramica o periapicales de la hemiarcada mandibular izquierda, donde se determinaron los estadios de calcificación del canino y el segundo premolar mandibulares izquierdos, por el método de Demirjian y colaboradores. Se calculó la concordancia entre los métodos evaluados, se encontraron altos coeficientes de concordancia y fue mayor en el sexo masculino y en el canino (Kappa= 0,913. Se concluyó que en la evaluación del potencial de crecimiento que presentan los pacientes de ortodoncia se puede sustituir la radiografía de la mano izquierda por radiografías periapicales del canino y el segundo premolar mandibulares izquierdos, lo cual permite la realización de las radiografías en el propio servicio de estomatología, con los beneficios que ello reporta en cuanto a mejor atención del paciente y ahorro de recursos.
