    Full Text Available Los tumores cardiacos representan el 0.2% y pueden ser primarios o metastásicos (secundarios, siendo estos últimos 20 a 40 veces más comunes que los primarios. De los tumores primarios, el 75% son benignos y aproximadamente el 50-85% de estos corresponden a mixomas, con una incidencia de 0.5-1 por 106 individuos por año. Se presenta el caso de un paciente de 56 años de edad, sin factores de riesgo cardiovascular ni antecedentes patológicos, con un mixoma auricular izquierdo de 4,6 × 4,5 cm, que prolapsaba hacia la válvula mitral en diástole provocando obstrucción intermitente de la misma y estenosis mitral severa. El diagnóstico se realizó mediante una ecocardiografía transtorácica, sin requerir de otras pruebas diagnósticas. Se realizó resección quirúrgica, lográndose la resección completa del tumor. La evolución posterior del paciente fue satisfactoria, siendo egresado a los 11 días de la intervención.

    Full Text Available Cochliomyia hominivorax es causante del 80% de las miasis humanas en la Argentina. En la actualidad, su distribución geográfica abarca Sudamérica tropical y gran parte de Argentina. En el presente informe se describen dos casos clínicos de otomiasis por C. hominivorax en pacientes pediátricos atendidos en el Hospital de Clínicas de Buenos Aires, Argentina. La importancia de la identificación taxonómica radica en el hecho de que esta especie produce cuadros graves debido a la capacidad de sus larvas de perforar el hueso y provocar la muerte del hospedador.Cochliomyia hominivorax causes 80% of human myiasis in Argentina. Nowadays, its geographic distribution covers tropical South America and an important region of Argentina. In the present report, two clinical cases of otomyiasis by C. hominivorax in pediatric patients assisted at the Hospital de Clinicas of Buenos Aires, Argentina are described. The relevance of the taxonomic identification lies in the fact that this species produces severe symptoms owing to the capacity of its larvae to drill the bones and cause the host's death.

    Full Text Available Avaliou-se a viabilidade do emprego da cartilagem auricular bovina conservada em glutaraldeído a 4% na hernioplastia experimental, empregando-se seis coelhos adultos, machos, da raça Nova Zelândia. Para obtenção da hérnia incisional, removeu-se um segmento elíptico de 3cm de comprimento por 1cm de largura, no ponto central à primeira incisão, envolvendo fáscia e tecido muscular, na região da cicatriz umbilical. Dois animais de cada vez foram sacrificados aos 15, 30 e 45 dias após a cirurgia. Nos sacrificados aos 15 dias, observaram-se áreas focais de inflamação, caracterizadas por abscesso e fístula. À microscopia, observou-se área de inflamação e necrose próxima à periferia do implante. Nas amostras colhidas dos animais sacrificados aos 30 dias, não foram evidenciadas alterações clínicas relevantes. Desses, um animal apresentou à microscopia intensa proliferação fibroblástica, moderada neovascularização e células inflamatórias predominantemente mononucleares. Dos sacrificados aos 45 dias, em um ocorreu aderência de alça intestinal ao implante. É possível inferir que o material implantado apresentou satisfatória compatibilidade com o tecido receptor. Conclui-se que o implante de cartilagem auricular bovina conservada na hernioplastia experimental em coelhos apresentou evidências de boa integração tecidual e cicatrização, não havendo eliminação do material implantado.The auricular cartilage preserved in 4% glutaraldehyde was used for experimental hernioplasty in six male, adult, New Zealand rabbits. To create an incision hernia, an elliptic tissue fragment three centimeter-long and one-centimeter wide was removed at a point centrally located from the first incision, embracing fascia and muscle tissue, from the area of umbilical scar. Animals were euthanized, two at a time, 15, 30, or 45 days after surgery. In the animals euthanized after 15 days focal areas of inflammation were observed

    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.

    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.

    Cochliomyia Townsend includes several abundant and one of the most broadly distributed, blow flies in the Americas, and is of significant economic and forensic importance. For decades, Cochliomyia hominivorax (Coquerel) and Cochliomyia macellaria (Fabricius) have received attention as livestock parasites and primary indicator species in forensic entomology. However, Cochliomyia minima Shannon and Cochliomyia aldrichi Del Ponte have only been subject to basic taxonomy and faunistic studies. Here we present the first complete phylogeny of Cochliomyia including numerous specimens per species, collected from 13 localities in the Caribbean. Four genes, the mitochondrial COI and the nuclear EF-1α, 28S rRNA, and ITS2, were analyzed. While we found some differences among gene trees, a concatenated gene matrix recovered a robustly supported monophyletic Cochliomyia with Compsomyiops Townsend as its sister group and recovered the monophyly of Cochliomyia hominivorax, Cochliomyia macellaria and Cochliomyia minima. Our results support a close relationship between Cochliomyia minima and Cochliomyia aldrichi. However, we found Cochliomyia aldrichi containing Cochliomyia minima, indicating recent speciation, or issues with the taxonomy of the group. We provide basic information on habitat preference, distribution and feeding habits of Cochliomyia minima and Cochliomyia aldrichi that will be useful for future forensic studies in the Caribbean.

    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

    Full Text Available La oreja, debido a su situación expuesta en la cabeza, es un órgano susceptible de sufrir múltiples traumas e incluso pérdida; así mismo, es asiento de neoplasias malignas, carcinomas y melanomas que igualmente finalizan en amputación. Fuera de estas razones, la ausencia congénita del pabellón auricular es la segunda malformación facial de origen congénito más frecuente después del labio y paladar fisurados. Es común por tanto para el cirujano plástico verse frente a pacientes que consultan solicitando la solución a su deformidad. El presente artículo trata de señalar el camino a seguir dividido en cuatro etapas de acuerdo a los principios definidos por el Dr. Radford Tanzer y perfeccionados a través de los años por el Dr. Burt Brent, e ilustra el manejo de la reconstrucción en casos de microtia, amputación auricular y el uso de colgajos de fascia temporal en los casos en que la piel de la región mastoidea ha sido comprometida y no es posible usarla como elemento primario para la reconstrucción auricular.Due to its very exposed situation on both sides of the head, the auricle is very susceptible to suffer severe traumas, that will at the end cause its amputation; it´s too one of the most common sites to present malignant tumors, carcinoma and melanoma, that will also end in the surgical amputation of the ear. Congenital absence of the ear, microtia, is the second most common facial anomaly after cleft lip and palate. Not infrequently plastic surgeon confronts with patients seeking an answer for correction of their deformities. The present article tries to show a four steps method, according to the principles described first by Dr. Radford Tanzer and later improved by Dr. Burt Brent and illustrates how to manage the auricular reconstruction in cases of congenital microtia or traumatic loss of the auricle, as well as the use of the temporal fascia flap as a way to provide skin coverage, when the skin of the mastoid area has

    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.

    MicroRNAs (miRNAs) are small noncoding RNAs that modulate gene expression through post-transcriptional regulation. Here, we report the identification and characterization of miRNAs in two closely related screwworm flies with different feeding habits: Cochliomyia hominivorax and Cochliomyia macellaria. The New World screwworm, C. hominivorax, is an obligatory parasite of warm-blooded vertebrates, whereas the secondary screwworm, C. macellaria, is a free-living organism that feeds on decaying organic matter. Here, the small RNA transcriptomes of adults and third-instar larvae of both species were sequenced. A total of 110 evolutionarily conserved miRNAs were identified, and 10 putative precursor miRNAs (pre-miRNAs) were predicted. The relative expression of six selected miRNAs was further investigated, including miRNAs that are related to reproduction and neural processes in other insects. Mature miRNAs were also characterized across an evolutionary time scale, suggesting that the majority of them have been conserved since the emergence of the Arthropoda [540 million years ago (Ma)], Hexapoda (488 Ma) and Brachycera (195 Ma) lineages. This study is the first report of miRNAs for screwworm flies. We also performed a comparative analysis with the hereby predicted miRNAs from the sheep blowfly, Lucilia cuprina. The results presented may advance our understanding of parasitic habits within Calliphoridae and assist further functional studies in blowflies. © 2016 The Royal Entomological Society.

    The primary screwworm fly Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) is one of the most important insect pests of livestock in neotropical regions, whereas Cochliomyia macellaria (Fabricius) (Diptera: Calliphoridae), the secondary screwworm, is of medical and sanitary importance because of its role in the dissemination of pathogens. These two species share morphological similarities and both may occur in the same myiasis, but in different developmental stages. In this work, the usefulness of PCR-RFLP (polymerase chain reaction - restriction fragment length polymorphism) of mitochondrial DNA (mtDNA) for the unambiguous identification of C. hominivorax and C. macellaria was investigated. Two specific regions of mtDNA were amplified: 870bp from Cytochrome oxidase subunit I and 2100bp from the A+T rich/12S region from C. hominivorax and C. macellaria specimens from different areas of Brazil. Reliable species-specific PCR-RFLP results were obtained for the CO I region and the A+T rich/12S region using the restriction enzymes Dra I and Ssp I. These results confirm the conservation of CO I diagnostic restriction sites previously reported and demonstrate the usefulness of the control region sequences as an efficient marker for PCR-RFLP identification of Brazilian screwworm flies. The occurrences of intraspecific polymorphic patterns are discussed based on frequencies and potential conflicts for species identification. PCR-RFLP provides a potentially useful method for identifying samples from the areas where these species are monitored.

    Growth curves were studied for the egg, larva, and pupa of the secondary screwworm, Cochliomyia macellaria (F), under mean cyclic temperatures of 15.6, 21.1, 26.7, 32.2, and a constant 25.0 degrees C. Development from egg to adult under all regimes ranged from 170 to 588 h. A constant temperature regime of 25 degrees C produced a range of pupation times from 92 to 142 h, with adult emergence ranging from 196 to 261 h. The maximal preferential temperature of 39 degrees C was determined for maggots by using a gradient system. The minimal variation in the range of larval lengths and development time makes this species suitable for establishing relatively narrow confidence intervals when constructing a postmortem interval estimate for use in legal investigations.

    Larvae of the secondary screwworm, Cochliomyia macellaria (F.), feed on carrion and may sometimes cause animal myiasis. They have been reared in the laboratory on various animal tissues to study their growth and development because of their importance in forensic science. We use secondary screwworms in our laboratory for preliminary experiments as a model for the primary screwworm, Cochliomyia hominivorax (Coquerel), which has been eradicated from the United States. C. macellaria larvae reared on animal tissues produced a putrid odor, an unfavorable condition in the laboratory, and variable pupal size and weight, bringing into question the validity of use as a model for C. hominivorax. Therefore, studies were conducted to develop a less odiferous artificial diet with reduced variability in resulting pupae by comparing three diets: 1) an artificial diet prepared from spray-dried blood, spray-dried poultry egg, dry milk substitute, and solidified with a polyacrylate polymer gel; 2) a fresh blood-based diet prepared similarly, except fresh bovine blood was used in place of spray-dried blood; and 3) a beef liver diet. Data from seven life-history parameters of resulting insects were collected and analyzed. Larval and pupal weights of C. macellaria reared on both the dry and fresh blood-based diets were significantly higher than those reared on the liver diet. Numbers of pupae and percentage of adult emergence were also significantly higher from both dry blood and fresh blood-based diets than those reared on the liver diet. Female flies developing from larvae reared on dry and fresh blood-based diets laid significantly more eggs than females developing from larvae reared on the liver diet. Results show that C. macellaria larvae developed and grew normally in the dry and fresh blood-based diets, indicating that an artificial diet can effectively replace the liver diet commonly used for rearing C. macellaria.

    The great auricular nerve can be damaged by the neck surgery, tumor, and long-time pressure on the neck. But, great auricular neuralgia is very rare condition. It was managed by several medication and landmark-based great auricular nerve block with poor prognosis. A 25-year-old man presented with a pain in the left lateral neck and auricle. He was diagnosed with great auricular neuralgia. His pain was not reduced by medication. Therefore, the great auricular nerve block with local anesthetics and steroid was performed under ultrasound guidance. Ultrasound guided great auricular nerve block alleviated great auricular neuralgia. This medication-resistant great auricular neuralgia was treated by the ultrasound guided great auricular nerve block with local anesthetic agent and steroid. Therefore, great auricular nerve block can be a good treatment option of medication resistant great auricular neuralgia.

    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.

  19. Cochliomyia Homnivorax in an advanced stage in the oral cavity

    Directory of Open Access Journals (Sweden)

    Layla Gomes

    Full Text Available Myiasis is characterized by the invasion of body or cavity tissues of live animals by larva. It is most frequently observed in underdeveloped and tropical countries, but there are cases described worldwide. Conventional treatment consists of mechanical removal of the larvae, one by one, which is a painful, embarrassing and repugnant process, both for the professional and patient. Although it is not considered rare, it has been observed that the dental professional has little knowledge for the diagnosis and treatment of this pathology. For this reason, this study reports a case of oral myiasis at an advanced stage, which affected a nine-year-old patient, treated at a medical-dental clinic. Diagnosis was based on the visual presence of Cochliomyia homnivorax larvae, diptera of the Calliphoridae family, which were between the second and third stages of development. Predisposing factors, such as the lack of information, malnutrition, poor oral hygiene, preexistenceof oral lesions and severe halitosis have a decisive influence in the appearance and progression of oral myiasis. A brief literaturereview was also conducted, in which this pathology was discussed, including the importance of early clinical diagnosis, its etiology, possible associations with other pathologies, and different types of treatment.

    Full Text Available The new world screwworm fly, Cochliomyia hominivorax, in larval stage is an obligate parasite of mammals and humans, causing traumatic myiasis. The female fly mates once in in its lifespan, whereas the male mates several times. Accordingly eradication efforts were established in the 1950’s, using male sterilization. Screwworm eradication has been successful in North and Central America, including some Caribbean islands. However, South America is still infested. Economic costs, the length of the program, and undesirable side effects of the screwworm eradication program led to a search for alternatives control measures. The initiation of screwworm eradication in Colombia could encounter geographical, political, and mainly economical problems. This program in Colombia would require the economic support and collaboration of the USDA, organizations of international cooperation, health authorities, academic institutions, and livestock producers. Priorities for screwworm research in Colombia should be biology, epidemiology and population dynamics, together with improvement of survey methods and control technologies. The achievement of studies for establishing technical, political, economical, and environmental viability of screwworm eradication is recommended. After these data are accumulated, a commission must be assembled with public and private organizations in order to determine the real cost and benefits of eradication.

    2012-08-01

    Leishmaniasis comprises a group of diseases transmitted by the bite of infected sand flies. There are three basic clinical forms of leishmaniasis: cutaneous, mucocutaneous and visceral. Leishmaniasis may mimic neoplastic lesions and other infectious diseases because of similar disease localisation, physical characteristics and histopathological findings. A 35-year-old man was referred to our clinic with a presumed diagnosis of angiolymphoid hyperplasia of the auricle; however, this lesion proved to be cutaneous leishmaniasis. The definitive diagnosis was reached by identifying the parasites on smears obtained from the lesion. It should be borne in mind that cutaneous leishmaniasis presenting as isolated auricular lesions may mimic neoplasia. In the present case report, we discuss auricular cutaneous leishmaniasis and we review the relevant literature.

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.

    1996-09-01

    The mitochondrial DNA of the secondary screwworm, Cochliomyia macellaria (F.), was cleaved with 15 restriction endonucleases to produce 54 restriction fragments. Forty-three restriction sites recognized by 12 enzymes were assigned positions on a restriction site map. Both the restriction fragments and the restriction site map were compared with published data from the screwworm, Cochliomyia hominivorax (Coquerel). The restriction site maps were aligned using a combination of highly conserved restriction sites. Estimated nucleotide divergence between the 2 species based on the fragments was 0.052. The divergence based on the restriction site map was 0.093. The data provide a baseline for future population or phylogenetic investigations.

    The blow fly Cochliomyia minima Shannon is endemic to the Caribbean, and it has great potential for forensic applications because of its abundance and broad distribution in the region. However, its larval stages are unknown. Here, I update previously published identification keys by describing for the first time the morphology of C. minima larvae. The larvae of C. minima are found to be very similar to those of Cochliomyia macellaria F., but the former can be easily identified by the oral sclerite completely pigmented, visible as a spike between mouth hooks. The description of C. minima larvae in this study will be useful to forensic scientists in the Caribbean region.

    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.

    Transformer (TRA) promotes female development in several dipteran species including the Australian sheep blowfly Lucilia cuprina, the Mediterranean fruit fly, housefly and Drosophila melanogaster. tra transcripts are sex-specifically spliced such that only the female form encodes full length functional protein. The presence of six predicted TRA/TRA2 binding sites in the sex-specific female intron of the L. cuprina gene suggested that tra splicing is auto-regulated as in medfly and housefly. With the aim of identifying conserved motifs that may play a role in tra sex-specific splicing, here we have isolated and characterized the tra gene from three additional blowfly species, L. sericata, Cochliomyia hominivorax and C. macellaria. The blowfly adult male and female transcripts differ in the choice of splice donor site in the first intron, with males using a site downstream of the site used in females. The tra genes all contain a single TRA/TRA2 site in the male exon and a cluster of four to five sites in the male intron. However, overall the sex-specific intron sequences are poorly conserved in closely related blowflies. The most conserved regions are around the exon/intron junctions, the 3′ end of the intron and near the cluster of TRA/TRA2 sites. We propose a model for sex specific regulation of tra splicing that incorporates the conserved features identified in this study. In L. sericata embryos, the male tra transcript was first detected at around the time of cellular blastoderm formation. RNAi experiments showed that tra is required for female development in L. sericata and C. macellaria. The isolation of the tra gene from the New World screwworm fly C. hominivorax, a major livestock pest, will facilitate the development of a “male-only” strain for genetic control programs.

    Transformer (TRA) promotes female development in several dipteran species including the Australian sheep blowfly Lucilia cuprina, the Mediterranean fruit fly, housefly and Drosophila melanogaster. tra transcripts are sex-specifically spliced such that only the female form encodes full length functional protein. The presence of six predicted TRA/TRA2 binding sites in the sex-specific female intron of the L. cuprina gene suggested that tra splicing is auto-regulated as in medfly and housefly. With the aim of identifying conserved motifs that may play a role in tra sex-specific splicing, here we have isolated and characterized the tra gene from three additional blowfly species, L. sericata, Cochliomyia hominivorax and C. macellaria. The blowfly adult male and female transcripts differ in the choice of splice donor site in the first intron, with males using a site downstream of the site used in females. The tra genes all contain a single TRA/TRA2 site in the male exon and a cluster of four to five sites in the male intron. However, overall the sex-specific intron sequences are poorly conserved in closely related blowflies. The most conserved regions are around the exon/intron junctions, the 3' end of the intron and near the cluster of TRA/TRA2 sites. We propose a model for sex specific regulation of tra splicing that incorporates the conserved features identified in this study. In L. sericata embryos, the male tra transcript was first detected at around the time of cellular blastoderm formation. RNAi experiments showed that tra is required for female development in L. sericata and C. macellaria. The isolation of the tra gene from the New World screwworm fly C. hominivorax, a major livestock pest, will facilitate the development of a "male-only" strain for genetic control programs.

    Cochliomyia macellaria (Diptera: Calliphoridae) is known as the secondary screwworm because it causes secondary or facultative myiasis when the larvae feed on necrotic tissues. This fly has a significant medical and veterinary importance since it has been reported to transport eggs of Dermatobia hominis (human botfly), which can cause significant economic losses to livestock. Since this screwworm has been collected colonizing both pig carcasses and human cadavers, it is considered one of the most important species for forensic entomology studies. Scanning electron microscopy (SEM) gives detailed information on the morphological characteristics which can help identify the immature forms of the flies. The aim of this study was to describe and analyze the morphological characteristics of the eggs, all the larval instars, and the puparia of Cochliomyia macellaria using SEM. The egg is ellipsoid and the dorsal surface is concave. The islands inside the median area had no anastomosis, but some perforations could be observed. From the second larval instar onwards, besides the intersegmental spines, other bands of spines were observed at the abdominal segments. Two spiracular openings were visible on the first and second larval instars, which were not expected. These characteristics are specific to Cochliomyia genus. The number and the general aspect of the spine tips in the cephalic region, the intersegmental bands on the abdomen, and the number of the spiracular openings could together help identify C. macellaria.

    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

    To determine the histologic relationship and distance between excised preauricular epithelial sinus tract and the adjacent auricular cartilage (sinocartilaginous distance) in a series of patients. The excision of preauricular sinuses is a common surgical procedure. Recurrences are frequent and can be technically challenging. While advocated by several authors, the surgical removal of adjacent auricular cartilage is not universally performed. Retrospective case series. Children's Hospital of Philadelphia. Fifty-two pediatric patients who underwent surgical excision of preauricular sinus tracts and adjacent auricular cartilage. Between September 1, 2005, and July 31, 2007, the preauricular sinus tracts and adjacent auricular cartilage were excised from 52 pediatric patients. A pathologist reviewed a total of 58 specimens to determine the relationship between epithelial tract and cartilage. The sinocartilaginous distance in microns. Patient ages ranged from 8 months to 17 years (mean age, 4 years). In all but 1 case, the tracts were in close proximity to the cartilage. The average sinocartilaginous distance was 472 mum (median distance, 400 mum); the 25th percentile was 250 mum. In over 50% of the specimens, the sinocartilaginous distance was less than 0.5 mm, and in nearly all of the these, the epithelial tract was in continuity with stromal tissue histologically indistinguishable from perichondrium. The observed sinocartilaginous distances suggest that it may be difficult to dissect most sinus tracts from the cartilage. The routine removal of a small portion of auricular cartilage along with the sinus tract may yield a more thorough excision and help to prevent recurrence.

    Auricular acupuncture (AA) is a therapeutic method by which specific points on the auricle are stimulated to treat various conditions. AA is often recommended as treatment for insomnia. The aim of this systematic review was to evaluate data from randomised, placebo-controlled clinical trials testing the effectiveness of AA for treating insomnia. We searched the literature using 18 databases from their inception to April 2008 without language restrictions. All prospective randomised clinical trials (RCTs) of AA for subjects with insomnia were considered. Methodological quality was assessed using the Jadad score. We identified 433 possible relevant articles, in which include 10 acceptable RCTs. The methodological quality of the trials was generally poor. Magnetic pellets AA was compared with placebo AA in three of the studies. The results suggested beneficial effects on sleep efficiency compared with placebo AA. One RCT tested needle AA compared with placebo AA and failed to show the effectiveness of AA. Four RCTs compared Semen Vaccariae or magnetic pellet AA with conventional drugs (estazolam or diazepam). Favourable effects for AA were found. Two RCTs tested thumbtack needle AA vs. no treatment suggested beneficial effects of AA on a sleep score. We conclude that, because of the paucity and of the poor quality of the data, the evidence for the effectiveness of AA for the symptomatic treatment of insomnia is limited. Further, rigorously designed trials are warranted to confirm these results.

    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.

    Auricular Acupuncture Diagnosis is a diagnostic method which is essential for the topographic identification on the auricle of the anatomical parts of the body carrying a particular ailment or dysfunction. To identify the specific zones related to lumbar hernia in patients treated with a series of epidural infiltrations with corticosteroids. In a consecutive group of thirty patients with lumbar hernia 2 diagnostic methods used in Auricular Acupuncture Diagnosis, Pain Pressure Test and Electric Skin Resistance Test, were applied before the first infiltration (T0), before the second and the third infiltration (T1, T2) and one week after the third infiltration (T3). The parameters, whose variations were analyzed at T0-T3, were the following: the number of points identified; the intensity of pain on a verbal rating scale and the foot-hand distance in cm with bent spine and extended knees. The identified points were reported on the Auricular Sectogram which is a validated graphic system suitable for a correct transcription of the points and indicated for a statistical analysis of their distribution on the different sectors. A significant association was found for some auricular areas, along the series of epidural infiltrations, with a progressive reduction in the number of tender and low electrical resistance points together with a decrease of pain and hand-foot distance. The auricular zones found with Auricular Acupuncture Diagnosis in our group of patients seem of clinical relevance and could be included in the complementary treatment of lumbar-sciatic pain in lumbar hernia.

    The life history traits of blow fly Cochliomyia macellaria (Fabricius, 1775) was studied under semi-controlled laboratory conditions at 29.14°C temperature, 72.53% relative humidity, and 12-h photoperiod. The raw data were analyzed based on the age-stage, two-sex life table, considering the development rates among individuals of both sexes. Cochliomyia macellaria survival rate was 0.43 (♂) and 0.40 (♀), while life expectancy was 17.9 (♂) and 20.9 (♀) days, for adult males and females, respectively. The total fecundity was 681.15 eggs/female, with an average of 3.65 batches/female and 199 eggs/batch. The intrinsic rate of increase (r) was 0.327 days-1, the finite rate of population increase (λ) was 3.35 days-1, the mean generation time (T) was 17.15 days, and the net reproduction rate (R 0 ) was 272.46 offspring/individual. The population parameters found here corroborates that C. macellaria population act as a r selected species under laboratory conditions. Additionally, development data and accumulated degree days (ADD) for each stage of C. macellaria are provided and its implications for the forensic use are discussed.

    New World screwworm populations in North and Central America have been the targets of virtually continuous eradication attempts by sterile insect technique (SIT) since the 1950s. Nevertheless, in some areas, such as Jamaica, SIT control programmes have failed. Reasons for the failure of SIT-based control programmes in some locations are unknown, but it has been hypothesized that failure may be related to mating incompatibility between sterile and wild fly populations or to the existence of sexually incompatible cryptic species. This paper outlines the development of a suite of four new microsatellite loci which can be used to study intra-specific relationships between populations of Cochliomyia hominivorax from the Caribbean and South America, which represent those populations involved in, or earmarked for, forthcoming SIT control. Cross-amplification with the secondary screwworm, Cochliomyia macellaria, was also successful with three of the new loci. We present results which suggest that populations from Trinidad and Jamaica form distinct groupings of flies and that C. hominivorax from Trinidad appears particularly distinct.

    Volatile chemicals from waste artificial larval media as well as from bovine blood inoculated with bacteria isolated from screwworm-infested wounds attract gravid females of Cochliomyia hominivorax Coquerel and Cochliomyia macellaria (F.). Chemicals identified from volatiles are dimethyl disulfide, dimethyl trisulfide, phenol, p-cresol, and indole; a blend of these attracted females to oviposit. Present studies investigated the effectiveness of these compounds, either in a blend or individually as potential oviposition attractants. Tests were conducted to determine the effects of gender, ovarian age, and the color and type of substrates on attraction response and oviposition of C. macellaria adults. Results showed that substrates treated with dimethyl trisulfide (DMTS) alone or the five-compound blend alone attracted significantly more gravid females than other chemicals. Black substrates treated with DMTS attracted more gravid flies than did the yellow substrates. Yellow substrates treated with indole attracted more males and nongravid females. In oviposition tests, females deposited significantly more eggs on meat-based substrates than those without meat. These findings suggest that several factors have to be considered for developing an effective oviposition attractant that should include effectiveness of individual chemicals used, the ratio of the chemicals in a blend, and their concentrations. Also, an effective trap design will need to consider using suitable color which will selectively attract gravid females.

A series of 234 consecutive patients who had undergone conventional cerebral angiography was analyzed. The posterior auricular artery was examined on the lateral projection of the external carotid or common carotid arteriography. The posterior auricular artery was classified into four groups by length, using the external auditory canal and the top of the helix as radiographical landmarks. Our proposed classification is as follows: Type A, posterior auricular artery terminates between its origin and the center of the external auditory canal; Type B, posterior auricular artery terminates between the center of the external auditory canal and the top of the helix; Type C, posterior auricular artery terminates between the top of the helix and the vertex; and Type D, posterior auricular artery reaches up to the vertex. A total of 424 (right, 214; left, 210) posterior auricular arteries were analyzed in 111 men and 123 women aged 11 to 91 years (mean, 61.0 years) examined for aneurysms in 78 cases, occlusive vascular diseases in 56, intracranial hemorrhages in 41, tumors in 35, and others in 24. Types A, B, C, and D were found in 15.1%, 34.9%, 48.8%, and 1.2% of the patients, respectively. A novel classification of the posterior auricular artery identifies four types based on its length on cerebral angiography.

    Full Text Available La fibrilación auricular es el trastorno del ritmo más frecuente luego de la cirugía cardíaca. En estudios previos se ha asociado a prolongación de la internación, aumento en los costos e incremento en la mortalidad. El objetivo de este estudio fue conocer la prevalencia de fibrilación auricular en el postoperatorio de cirugía cardíaca y determinar el efecto en el tiempo de estadía hospitalaria. Se analizaron retrospectivamente las historias clínicas de pacientes sometidos a cirugía cardíaca consecutivamente (de revascularización miocárdica, valvulares o ambas entre enero 2006 y noviembre 2008. El punto final evaluado en el postoperatorio fue la presencia de fibrilación auricular. Se dividió a la muestra en dos grupos según tuvieran o no fibrilación auricular, y se compararon las variables clínicas y el tiempo de estadía hospitalaria. Ciento setenta y dos pacientes fueron operados en este período. Se excluyeron del análisis siete pacientes por falta de datos. La edad media fue 64.2 ± 9.5 años, con predominio del sexo masculino. La fibrilación auricular fue la complicación más frecuente (23.6%. El tiempo promedio de internación fue 6.7 ± 4.6 días. No hubo diferencias relevantes al comparar la estadía hospitalaria entre los grupos con o sin fibrilación auricular, 7.5 ± 4.1 días vs. 6.5 ± 4.7 días respectivamente, p = 0.21. La presencia de fibrilación auricular no prolongó la hospitalización. Probablemente una estrategia de prevención indiscriminada no sería costo-efectiva.

    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.

    To investigate the feasibility of spray drying technology of Auricularia auricular extract and its optimum process. On the basis of single factor test, with the yield of dry extract and the content of polysaccharide as indexes, orthogonal test method was used to optimize the spray drying technology on the inlet air temperature, injection speed and crude drug content. Using ultraviolet spectrophotometry, thin layer chromatography(TLC) and pharmacodynamics as indicators, extracts prepared by traditional alcohol precipitation drying process and spray drying process were compared. Compared with the traditional preparation method, the extract prepared by spray drying had little differences from the polysaccharide content, TLC and the function of reducing TG and TC, and its optimum technology condition were as follows: The inlet air temperature was 180 °C, injection speed was 10 ml/min and crude drugs content was 0. 4 g/mL. Auricularia auricular extract by spray drying technology is stable and feasible with high economic benefit.

    In a 51-year-old man who had visited Surinam, cutaneous myiasis was diagnosed, caused by simultaneous infestation with the larvae of two different species of flies: Dermatobia hominis and Cochliomyia hominivorax. On his right lower arm the man had two solitary, furuncle-like lesions with a central breathing hole. Two days after these holes had been occluded with vaseline, two white larvae of D. hominis emerged. On both ankles the man had large, undermined ulcers containing hundreds of creeping larvae about 2 cm in length with a salmon-like colour: C. hominivorax. The larvae were removed from the ulcers by hand and by rinsing with physiological saline, after which the wounds healed rapidly. Myiasis is seen in the Netherlands mostly in people returning from a holiday in myiasis-endemic areas.

    Cochliomyia macellaria (Diptera: Calliphoridae), known as the secondary screwworm, occurs in the Americas and has medical-veterinary and forensic importance. This study aimed to describe the seasonal fluctuation of this species in the Pantanal region, Central-Western Brazil. From December 2004 to November 2007 fly catches using four windoriented traps baited with decaying bovine liver were carried out at the Nhumirim ranch, Nhecolândia subregion, Southern Pantanal. Traps remained active throughout the study period and collections were carried out on a weekly basis. A total of 159,397 Calliphoridae were caught and C. macellaria (57.33%) was the most abundant species. C. macellaria occurred all over the year showing a bimodal behavior with peaks in May-July (late autumn/early winter) and October-December (spring).

    The objective of this study was to characterize, structurally and ultrastructurally, the spermatozoa of the screwworm flies Cochliomyia hominivorax and Cochliomyia macellaria. To visualize the ultrastructure of microtubules and identify basic proteins, techniques such as the tannic acid fixation and the cytochemical method of ethanolic phosphotungstic acid (EPTA) were used. These methods of fixation are important because they reinforce the evidence of the protofilaments present in the microtubular wall and identify basic proteins, respectively. With the tannic acid fixative it was possible to observe a significant number of microtubules in the cell cytoplasm during spermiogenesis. Microtubules were observed in all regions of spermatids (head, 'overlap' zone and tail). The EPTA technique highlighted the presence of basic proteins on the border of the nucleus and nuclear envelope in the two species analyzed, and in the centriolar adjunct and on the border of mitochondrial derivatives in C. macellaria. The axoneme is of a conventional insect type with a 9 + 9 + 2 microtubular arrangement and the spermatozoa of C. hominivorax and C. macellaria are similar to those described for other Brachycera. The spermatozoa are long and thin in these two species, ∼190 µm in length, of which the head region measures ∼26 µm in C. hominivorax and 29 µm in C. macellaria. A polymorphism was observed in C. hominivorax and C. macellaria. These features are consistent with the structural diversity of the dipteran spermatozoa, constituting an essential tool for understanding the complex variations found in the Diptera order.

    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

    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.

    Full Text Available The ear has a reflexive property; therefore, various physical attributes may appear on the auricle when disorders of the internal organs or other parts of the body exist. Auricular diagnostics is an objective, painless, and noninvasive method that provides rapid access to information. Thus, the association between auricular signals and coronary heart disease (CHD should be further investigated. A case control study was conducted to determine the predictive value of auricular signals on 100 cases of CHD (CHD+ve = 50; CHD−ve = 50 via visual inspection, electrical skin resistance measurement, and tenderness testing. The results showed that the presence of an ear lobe crease (ELC was significantly associated with coronary heart disease. The “heart” zone of the CHD+ve group significantly exhibited higher conductivity on both ears than that of the controls. The CHD+ve group experienced significant tenderness in the “heart” region compared with those in the CHD−ve group in both acute and chronic conditions. Further studies that take into consideration the impact of age, race, and earlobe shape on ELC prevalence in a larger sample should be done.

    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.

    Auricular therapy includes acupuncture, electroacupuncture, acupressure, lasering, cauterization, moxibustion, and bloodletting in the auricle. For 2500 years, people have employed auricular therapy for treating diseases, but the methods have been limited to bloodletting and cauterization. Only after 1957, the international scientific community became aware that the map of the ear resembles an inverted fetus, its introduction has led to auricular acupuncture (AA) becoming a more systemic approach, and, following the identification and standardization of more precise points, AA has been employed in clinical applications. The mechanisms of AA are considered to have a close relationship with the autonomic nervous system, the neuroendocrine system, neuroimmunological factors, neuroinflammation, and neural reflex, as well as antioxidation. Auricular therapy has been applied, for example, for pain relief, for the treatment of epilepsy, anxiety, and obesity, and for improving sleep quality.

    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

    One of the most common complications of total auricular reconstruction is delayed wound healing, which results in skin necrosis and exposure of the ear framework. Various options exist for salvage of the exposed ear framework. From January 2009 to May 2014, 149 patients underwent total auricular reconstruction using an autogenous cartilage framework or porous polyethylene framework (Medpor; Stryker, USA). An autogenous cartilage framework was used in 48 patients, and a Medpor framework was used in 101 cases. Three cases of framework exposure (3/48, 6.3%) were observed among the patients treated with an autogenous cartilage framework. In contrast, framework exposure took place in 11 patients who were treated with a Medpor framework (11/101, 10.9%). Depending on the method of total ear reconstruction and the location of exposure, the authors used local skin flaps, temporoparietal fascia flaps, deep temporal fascia (DTF) flaps, or mastoid fascia (MF) flaps with skin grafting. Among the 11 patients who experienced framework exposure after being treated with a Medpor framework, a DTF flap with skin grafting was used in 6 patients and an MF flap with skin grafting in 6 patients; 1 patient was treated with both a DTF flap and an MF flap. All 3 cases of cartilage framework exposure were salvaged using a temporoparietal fascia flap with skin grafting, and a local skin flap was used in 1 case. In all 3 cases, the exposed framework was completely covered with the flap, and the reconstructed ears showed well-defined convolutions. Salvage of framework exposure remains a challenging issue in total auricular reconstruction. However, appropriate wound management using various flaps allows the reconstructed ear to be safely preserved.

    Full Text Available La presencia de pliegue diagonal auricular debe alertar al médico para entender su asociación con la enfermedad cardíaca coronaria y la enfermedad isquémica del corazón, especialmente en aquellos pacientes asintomáticos o pacientes con factores de riesgo tradicionales y no tradicionales. Por lo tanto, esta anormalidad puede ser interpretada como un "marcador cutáneo" de la enfermedad cardíaca coronaria. Este signo también podría servir para identificar mejor a los grupos de alto riesgo cardiovascular y para comenzar con la implementación de las medidas de las estrategias de prevención. Hay otros signos clínicos, además del pliegue de la oreja, que pueden reflejar el envejecimiento arterial y aterosclerosis, independientemente del número, duración o alcance de los factores de riesgo cardiovascular tradicionales. El hallazgo de pliegue auricular no debe sustituir a una historia clínica completa, la aplicación de métodos detallados, exámenes de laboratorio y físicos utilizados con excelente rendimiento en el diagnóstico de la enfermedad coronaria en la actualidad.

    Duane syndrome is a congenital cranial dysinnervation disorder involving absent or anomalous innervation of the lateral and medial rectus muscles that is sometimes associated with other manifestations of dysinnervation. We describe a patient with right esotropic Duane syndrome with a long-standing retroauricular tugging sensation in right gaze who was noted to have prominent ipsilateral oculo-auricular phenomenon, representing either abnormal enhancement of existing innervation or an uncommon dysinnervation. After successful strabismus surgery the tugging sensation improved but the phenomenon could still be elicited. Copyright © 2016 American Association for Pediatric Ophthalmology and Strabismus.

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.Atrial fibrillation is the most frequent cardiac arrhythmia in adults.

    The ethnobotanical uses of Brazilian plants for different injuries and diseases conjoined with local rich biodiversity represent an important resource for research and development. This study aimed to characterise BDEO and its in vitro activity on the third instar larvae (L3) of Cochliomyia macellaria. Groups of 20 L3 were placed on filter paper impregnated with increasing concentrations of 5-30% (v/v), equivalent to 0.79-4.77 μL/cm2, solubilised in ethanol or acetone. The major constituents of BDEO were β-pinene (9.94%), D-limonene (9.59%), β-nerolidol (7.93%), caryophyllene (7.69%), spathulenol (6.69), α-muurolene (6.74%) and α-pinene (5.31%). Lethal concentrations of 50% for BDEO on C. macellaria (LC50) after 24 and 48 h of exposure were 2.63 and 2.47 μL/cm2 for ethanol and 9.58 and 8.11 μL/cm2 for acetone, respectively. Furthermore, larvae cuticle abnormalities and adult deformity were observed. Our data confirm the effectiveness of BDEO as an ecofriendly product against blowflies.

    In this study we investigated the larval dispersal associated with larval predation in experimental populations of Chrysomya albiceps and Cochliomyia macellaria. Frequency distribution of sampling units (G test) in the substrate was used to evaluate variation in larval dispersal. An experimental acrylic channel (1 x 0.1 x 0.2 m) covered with wood shavings was used to observe larval dispersal prior to pupation. The acrylic channel was graduated at 0.05 m intervals, each representing a sampling unit; hence, 20 sampling units were set up. A Petri dish containing third instar larvae of single and double species was deposited at one edge of the acrylic channel allowing larvae to disperse. The number of buried pupae (0, 1, 2, n) present in each sampling unit was recorded. For double species, the number of recovered larvae of C. albiceps was similar to the number initially released on the dish Petri. On the other hand, the number of recovered larvae of C. macellaria was significantly smaller than the initially released number. The results show that C. albiceps attacks C. macellaria larvae during the larval dispersal process. The larval distribution of C. albiceps did not differ significantly from C. macellaria in double species, but it differed significantly in single species. The larval aggregation level of C. macellaria decreased when C. albiceps was present and the larval aggregation level of C. albiceps increased when C. macellaria was present. The implications of such findings for the population dynamics of these species are discussed.

    The secondary screwworm, Cochliomyia macellaria (F.), is an important blowfly species affecting both livestock and humans. It can transmit pathogenic disease agents mechanically and is an agent of facultative myiasis, which leads to economic losses. The adult flies are attracted to decomposing carcasses, carrion, or rotten meat in order to deposit their eggs, and the hatched larvae develop on these decaying organic materials. This research was aimed to identify volatiles emitted from rotten chicken livers that were reported previously to attract gravid females. In laboratory oviposition assays, gravid females laid significantly more eggs on rotten livers than on fresh livers, and rotten chicken liver was more attractive than rotten beef liver. Volatiles from the two livers were collected using solid phase microextraction. Significantly different volatile profiles were detected from the rotten livers of beef and chicken. Electroantennography (EAG) was performed to determine antennal responses to chemicals released from the most attractive chicken liver that are candidate oviposition attractants. Seven compounds from rotten chicken liver elicited significant EAG responses from antennae of gravid females. Oviposition assays showed that the 7-component blend stimulated gravid females to lay significantly more eggs than the other combinations tested. This 7-component blend may have potential for use in monitoring and sampling populations of secondary screwworm and their associated disease epidemiology.

    Abstract. An evaluation was made of the post-embryonic development of three species of calliphorids in pasty dog food, which has a larger facility of storage, less cost and greater validity that nature diet (meat. The experimental phases took place in different conditions of temperature (T and humidity (RH: Chrysomya megacephala (Fabricius (3rd generation in a climatized chamber (T: 30oC, RH: 60± 10%, 14 hours photophase, Cochliomyia macellaria (Fabricius (2nd generation in environmental conditions (T: 22.3 - 24.0ºC, RH: 60 - 90%, and Chrysomya putoria (Wiedemann (1st generation in environmental conditions (T: 21.5 - 25.0 ºC, RH: 60 - 90%. Meat was used as the control. Each treatment was repeated four times, with 40 neolarvae/120 grams of diet/repetition. The duration of the C. megacephala stages and the survival rate (>85% were similar to those obtained with the control. In the artificial diet, the duration of the stages of larvae and of neolarvae to adult C. macellaria were significantly larger, but were not significant for the pupal stage, which showed smaller pupae and lower survival rates. The duration of the stages in C. putoria did not differ significantly, and the pupae were significantly smaller in the artificial diet, while the survival rates of the development stages were similar in the two diets. The artificial diet proved efficient for breeding C. megacephala and C. putoria.

    The secondary screwworm, Cochliomyia macellaria (Fabricius), was reared on either equine gluteus muscle or porcine loin muscle at 20.8 degrees C, 24.3 degrees C, and 28.2 degrees C. C. macellaria needed approximately 35% more time to complete development when reared at 20.8 than 28.2 degrees C. Furthermore, larval growth and weight over time did not differ between larvae reared on equine versus porcine muscle. This study is the second in the United States to examine the development of C. macellaria and is the first to examine development of this species on muscle tissue from different vertebrate species. These data could provide significant information regarding time of colonization, including myiasis and neglect cases involving humans and animals. Furthermore, these results in comparison with the only other data set available for this species in North America indicate a fair amount of phenotypic variability as it relates to geographic location, suggesting caution should be taken when applying these data to forensic cases outside the region where this study was conducted.

    The screwworm, Cochliomyia hominivorax (Coquerel), is one of the most important pests of livestock in the Western Hemisphere. During early immature stages it is morphologically very similar (first instars are virtually indistinguishable) to the secondary screwworm, C. macellaria (Fabricius). Here, the utility of the random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) was explored as a technique for developing molecular genetic markers for these two species. Of the 120 arbitrary primers screened, 21 primers produced markers that were further investigated. Seven of the 21 primers produced clear and reproducible markers that were tested with DNA of five individuals from four populations of each species; five of these primers showed 12 RAPD markers that differentiated the species in all populations. Analyses of data from these seven primers also suggested that intraspecific polymorphisms exist that could be useful in distinguishing populations of screwworms. Some population genetic tools, such as genetic distance, cluster analysis and bootstrapping, were used to statistically explore these polymorphisms. The resulting statistics showed 100% support for the ability of RAPD-PCR to discriminate between the two species. Bootstrapping with data from one of the genetic distance calculations produced a tree with all individual screwworms in the correct populations, indicating that RAPD-PCR has promise for displaying intraspecific genetic variation that could be used in establishing the general geographic origin of screwworm samples.

    Bacteria were isolated and identified from the digestive tract of the secondary screwworm, Cochliomyia macellaria (F.) (Diptera: Calliphoridae), and their role in the larval development of this insect was assessed in laboratory bioassays. The analysis of 16S rDNA sequences revealed that the bacterial isolates represented four species: Providencia sp., Escherichia coli O157:H7 (Escherich), Enterococcus faecalis (Orla-Jensen), and Ochrobactrum sp. (Holmes). Developmental assays demonstrated that C. macellaria larvae are able to develop on a sterile blood agar, and no bacteria are required to complete larval development. Indeed, developmental times were shorter and survival rates of C. macellaria on a sterile blood agar and the modified Harris rearing diet were greater compared with that on the blood agar inoculated with individual and mixed bacterial isolates. The cultures of Ochrobactrum sp. and E. faecalis supported larval development to a significantly greater extent than those of Providencia sp. and E. coli O157:H7. The presence of bacteria in newly emerged C. macellaria adults also was assessed and revealed that the bacteria in the gut of larvae can survive pupation and colonize the gut of adult flies. This study shows that development of larvae of C. macellaria does not depend on bacteria and that some bacterial isolates negatively impact larval development.

    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

The patient presented to our emergency department. The patient had chronic obstructive pulmonary disease and was completely unable to take deep breaths and clear secretions from his bronchial tree. After obtaining informed consent, we applied auricular acupuncture to ameliorate pain and hopefully improve his functional ability to cough and breathe deeply. Within a few minutes, his pain scores diminished considerably, and his ventilation and oxygenation indices improved to safe limits. Auricular acupuncture analgesia lasted for several hours. Parallel to pain reduction, hemodynamic disturbances and anxiety significantly resolved. A second treatment nearly a day later resulted in almost complete resolution of pain that lasted at least 5 days and permitted adequate ventilation, restored oxygenation, and some degree of mobilization (although restricted due to a compression fracture of a lumbar vertebra. Nonopioid and opioid analgesics were sparsely used in low doses during the entire hospitalization period. Hemodynamic alterations and anxiety also decreased, and the patient was soon ready to be discharged.

    Although the rectal mucosa remains the traditional site for measuring body temperature in dogs, an increasing number of clinicians have been using auricular temperature to estimate core body temperature. In this study, 88 mature healthy dogs had body temperatures measured with auricular and rectal thermometers. The mean temperature and confidence intervals were similar for each method, but Bland-Altman plots showed high biases and limits of agreement unacceptable for clinical purposes. The results indicate that auricular and rectal temperatures should not be interpreted interchangeably.

    Neuropraxia of the greater auricular nerve is an uncommon complication of shoulder surgery, with the patient in the beach chair position. The greater auricular nerve, a superficial branch of the cervical plexus, is vulnerable to neuropraxia due to its superficial anatomical location. In this case series, we present three cases of neuropraxia associated with direct compression by a horseshoe headrest, used in routine positioning for uncomplicated shoulder surgery. We outline the risk of using devices of this nature and discourage the use of similar headrest devices due to the potential complications in headrest devices that exert pressure on the posterior auricular area to maintain head position during surgery.

    Full Text Available This paper registers reports about dipterans made by three Portuguese who lived in Brazil during the 18th century. Luiz Gomes Ferreira, in his book "Erário mineral" ["Mineral revenue"], wrote curious passages related with myiasis-causing flies of the genus Cochliomyia. José Rodrigues de Mello registered, in Latin verses, the folklore for curing myiases caused by Cochliomyia hominivorax in cattle. Luiz dos Santos Vilhena, in the last of his twenty letters dealing with several aspects of life in Brazil, made reference to horseflies, human bot flies and mosquitos.

    Full Text Available 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.

    Squamous cell carcinoma (SCC) is well documented in snow leopards ( Uncia uncia ) and most common locations are oral, facial, or pedal. These two cases illustrate an unusual auricular presentation, which is more often reported in white domestic cats. The animals were aged and presented clinical signs of otitis such as head shaking and ear scratching. Clinical examinations showed auricular canal masses with chronic purulent otitis. In both cases, clinical deterioration led to euthanasia and histology of the ear canal was consistent with SCC and showed numerous vascular emboli. These cases illustrate an unreported aggressive localization for SCC in snow leopards, which should be included in the differential diagnosis of otitis in this species. Auricular SCC may be underdiagnosed as the ear canal is infrequently sampled for histopathology. This auricular localization should be considered when metastases are found upon necropsy without internal primary tumor.

    Full Text Available A criação massal da mosca da bicheira, Cochliomyia hominivorax (Diptera: Calliphoridae, para programas que utilizam a Técnica do Inseto Estéril nas Américas faz parte de um dos maiores programas do mundo de criação de insetos em larga escala. A maior parte do custo e do trabalho necessários para a produção massal está relacionada com a dieta larval, o que torna importante o seu aprimoramento levando-se em conta sua eficiência, custo e praticidade. Neste trabalho, foram realizados dois bioensaios com dietas alternativas feitas a partir de produtos disponíveis no mercado brasileiro com o objetivo de avaliar a viabilidade e eficiência dessas dietas para criações de mosca da bicheira no Brasil. Foram testadas duas dietas líquidas (tendo como bulking agents bagaço de cana ou fibra de coco, uma de carne, e outra de gel. Os parâmetros biológicos (peso das larvas, viabilidade larval, peso de pupas, porcentagem de emergência de adultos e razão sexual estiveram, em todos os casos, dentro de parâmetros satisfatórios para a criação laboratorial de C. hominivorax e as dietas não diferiram estatisticamente entre si. Devido a vantagens importantes, como alta viabilidade larval e menor custo, recomenda-se a dieta de gel para as criações de larvas da mosca da bicheira no Brasil.

    Full Text Available The species Cochliomyia hominivorax, also known as screwworm fly, is an obligate parasite of warm- blooded animals and its geographic range extends thoughout South America, except Chile. This fly causes significant economic losses and has great importance in Brazil. Few studies have focused on the excretion and secretion products of this species, and this research aimed to study the enzymes present in the secretion and excretion (E/S products of the three larval instars of C. hominivorax. The E/S profile of proteins was obtained by polyacrylamide gel electrophoresis and proteolytic activity was analyzed using gelatin, azocasein and Na-benzoyl-arginine-nitroanilide as substrates.  In E/S products of the three instars, proteins were detected with an apparent molecular weight ranging between 116 and 20 kDa. In the azocasein assay, at different pH ranges, the major proteolytic activity occurred at pH 7.5 for all larval instars. Assays were performed using the same substrates   in which the samples were treated with the inhibitors Benzamidine, Pepstatin A, 4-(2-Aminoethyl benzenesulfonyl fluoride hydrochloride (AEBSF, N-α-tosyl-L-lysine chloromethyl ketone (TLCK, N-α- tosyl-L-phenylalanine chloromethyl ketone (TPCK, Ethylenediamine tetraacetic acid (EDTA, and Leupeptin-trans-Epoxysuccinyl-leucylamido(4-guanidino butane (E-64. Proteinases present in the E/S product of first larvae instar are mostly serine trypsin and chymotrypsin proteases, whereas for second and third instars serine proteases and aspartyl proteases were predominantly observed. Biochemical characterization of E/S products of all larval stages of C. hominivorax helps to improve the understanding of the physiology and the interaction of this parasite with host tissues.

    Forensic entomologists rely on published developmental datasets to estimate the age of insects developing on human remains. Currently, these datasets only represent populations of targeted insects from specific locations. However, recent data indicate that populations can exhibit genetic variation in their development, including signatures of local adaptation demonstrated by regionally distinct plastic responses to their environments. In this study, three geographically distinct populations of the secondary screwworm, Cochliomyia macellaria Fabricius (Diptera: Calliphoridae; College Station, Longview, and San Marcos, TX, USA), a common blow fly collected from human remains in the southern USA, were reared in two distinct environments (cool 21 °C, 65 % relative humidity (RH); and warm 31 °C, 70 % RH) over 2 years (2011 and 2012) in order to determine differences in development time and mass. Significant differences in immature and pupal development time, as well as pupal mass, were shown to exist among strains derived from different populations and years. For immature development times, there was evidence of only an environmental effect on phenotype, while genotype by environment interactions was observed in pupal development times and pupal mass. College Station and San Marcos populations exhibited faster pupal development and smaller pupal sizes in the cooler environment relative to the Longview population, but showed an opposite trend in the warm environment. Rank order for College Station and Longview populations was reversed across years. Failure to take genetic variation into consideration when making such estimates can lead to unanticipated error and bias. These results indicate that genetics will have little impact on error when working with Texas genotypes of C. macellaria at ~30 °C and 70 % RH, but will have a more meaningful impact on error in postmortem interval estimates with this species in cooler, drier environments.

    The objective of this study was to analyse whether auricular acupuncture, acupuncture at the outer ear, could reduce state anxiety before dental treatment. This prospective, randomised patient-blinded study with 182 patients compared anxiety before dental treatment following auricular acupuncture at the relaxation-, tranquillizer- and master cerebral points (auricular acupuncture group) versus acupuncture at sham points (finger-, shoulder- and tonsil points; sham group) and a non-intervention control group. Anxiety was assessed using the Spielberger State Trait Anxiety Inventory (German version) before auricular acupuncture and 20 min thereafter, immediately before dental treatment. Auricular acupuncture reduced state anxiety score more effectively from 54.7 ± 10.8 to 46.9 ± 10.4 (mean ± SD) than sham acupuncture from 51.9 ± 10.2 to 48.4 ± 10.0. In contrast, state anxiety in the control group increased from 51.0 ± 11.7 to 54.0 ± 11.6 (mean increase +3.0; CI +4.7 to +1.2). The decrease in state anxiety in both intervention groups was statistically significant (p anxiety, the reduction in anxiety was -7.3 score points (CI -9.0 to -5.6) in the auricular acupuncture group and -3.7 score points (CI -5.4 to -1.9) in the sham group (p = 0.008). Auricular acupuncture, a minimally invasive method, effectively reduces state anxiety before dental treatment. Auricular acupuncture could be an option for patients scheduled for dental treatment, who experience an uncomfortable degree of anxiety and request an acute intervention for their anxiety.

    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.

Trinta e um estabelecimentos veterinários consultados atenderam pelo menos um caso de miíase em cães durante 2000. Os cães de raça definida, adultos e com pelagem longa e escura, residentes em casas, foram os mais acometidos, enquanto não foi observada predileção por sexo. Os ouvidos foram o local do corpo mais afetado pelas miíases, devido a otites. Os meses mais quentes do ano foram mencionados como os de maior ocorrência. A maioria dos proprietários não tentou tratar seus animais por conta própria e, com o tratamento adequado da ferida, prescrito pelo médico veterinário, o período de cura foi curto e não houve complicações durante e após o tratamento. Apesar das miíases serem consideradas uma conseqüência da negligência do proprietário, alguns cães já tinham apresentado esta enfermidade anteriormente. Devem ser desenvolvidos programas preventivos baseados nos fatores predisponentes identificados em inquéritos, tais como características fenotípicas dos animais mais acometidos e locais do corpo mais afetados. Causas que favoreçam a instalação de miíases, tais como otites e feridas diversas, devem ser controladas e a higiene ambiental deve ser mantida. Além disso, é necessária a intensificação dos programas preventivos nos períodos de maior incidência da enfermidade.

    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.

    To supply literature for developing an international standard of auricular acupuncture points. Electronic database searches were conducted in the Chinese National Knowledge Infrastructure and VIP, and the Western databases, Pubmed, the National Science and Technology Library, and the German Journal of Acupuncture, from 1990 to April, 2012. We also searched the documents of international symposiums for auricular acupuncture points (AAPs). Keywords were "auricular points", "auricular acupuncture points", "ear points", or "auriculotherapy". Basic and clinical research on AAPs was performed in China, the United States, France, and Germany. Clinical AAP research was done in Italy, Austria, Switzerland, Spain, the UK, Holland, Japan, Russia, and Africa. However, AAP research was not communicated internationally. The World Federation of Acupuncture-Moxibustion Societies recommended international standard of auricular acupuncture points (ISAAPs). Standardized nomenclature and locations of AAPs would provide a solid basis to draft an international standard organization. Experts need to find common points from different countries or regions, provide evidence of different ideas, and list the proposal as a recommendation for an international standard.

  9. Intraparotid Location of the Great Auricular Nerve: A New Anatomical Basis for Gustatory Sweating Syndrome.

    Gustatory sweating syndrome (also known as Frey syndrome or auriculotemporal nerve syndrome) is thought to result from a lesion of the auriculotemporal nerve. A lesion of this nerve can lead to aberrant regeneration of nerve fibers to the sweat glands and blood vessels. The occurrence of signs outside the region of the auriculotemporal nerve prompted the author to search for another anatomical basis for this syndrome. The author dissected 46 great auricular nerves from their origin to the parotid gland and in the infratemporal fossa. The author investigated the different connections of the great auricular nerve with the facial nerve and the auriculotemporal nerve. The great auricular nerve was found to essentially be a parotid nerve. There was a set of intraparotid nerve connections on 14 of the 46 half-heads that were dissected. The author was able to discern three types of parotid great auricular nerve connections, which he designates as either type 1, connection with the trunk of the facial nerve and its branches; type 2, connection with the auriculotemporal nerve; or type 3, connection with the auriculotemporal nerve and the facial nerve with the formation of an intraparotid nerve circle. Having clearly established the nerve connections of the great auricular nerve, the author believes that it is primarily this nerve that is responsible for gustatory sweating syndrome. This allows for a better understanding of the sympathetic nervous system features and the manifestation of the syndrome outside the region of the auriculotemporal nerve.

    Experience with anatomical dissection has suggested that two potential complications of rhytidectomy are related to the anatomy of the periauricular adipose compartments: great auricular nerve injury and the "subauricular band" phenomenon. This study describes this anatomy and its relationship to these potential complications. The results of 24 fresh hemifacial cadaver dissections were included in this study. Injections included the use of methylene blue and fixable dye injected into specific regions around the ear. The study incorporated digital macro photography, time-lapse photography, and three-dimensional cross-sections in multiple planes (coronal, sagittal, and axial planes) to identify structural relationships. This study defined five periauricular adipose compartments. The main branch of the great auricular nerve always ran within the subauricular membrane. The subauricular membrane was located between the subauricular and inferior adipose compartments. Inadequate dissection of the lateral neck and postauricular area along with failure to release this membrane completely results in banding of the lateral neck, a stigma of face lift surgery. McKinney's point was consistently found to lie where the great auricular nerve travels deep to the inferior border of Lore's fascia and the tail of the parotid. Below this point, the great auricular nerve is closer to the skin surface and more susceptible to potential injury. Two possible complications of rhytidectomy, great auricular nerve injury and the "subauricular band" phenomenon, are avoidable by understanding the anatomy of the periauricular adipose compartments.

    This paper aims to highlight the efficiency of auriculotherapy in the treatment of hot flushes, especially in cancer-related menopausal transition. We used systematically collected data from patients in 2014 in a medical oncology practice. The treatment was made according to the guidelines of The Inter-University Diploma and the cartography of the World Health Organization; data on satisfaction were collected orally. In 2014, 49 patients, among whom 41 had cancer, were treated for hot flushes. Although it is not recommended to treat several symptoms during the same session, we dealt with 1.7 symptoms per session on average. Sixty-nine percent of the patients were satisfied. We lacked data for nine patients, who did not come to the minimal recommended number of treatments (three). Only one patient among those who did not observe any improvement received three treatments. Auricular acupuncture is a safe and cheap method to treat hot flushes. It has been effective in numerous and various cases, among which were patients who presented cancer-related menopausal symptoms. It may be applied for a large variety of other symptoms.

    Postoperative nausea and vomiting (PONV) affects more than 30% of surgical patients. Auricular acupuncture (AA) has been shown to decrease the incidence of PONV in select populations. An evidence-based quality improvement project made AA available to all adult surgical patients, and the results were recorded in a database. A retrospective between-groups analysis of 210 database entries was conducted, of those 25 receiving AA. More risk factors for PONV were present in the AA group (P < .001). Both groups experienced a less-than-expected rate of PONV. Similar rates were shown between groups for PONV, postanesthesia care unit length of stay, and opioid consumption. Patient satisfaction was 96% with AA. The AA group was treated with less antiemetic medication (P < .001), yet PONV rates remained similar. A multimodal approach treating patients at risk for PONV is recommended. Administration of multiple antiemetics may result in unnecessary cost or unfavorable side effects when effective and less costly alternatives exist. AA is a viable treatment for PONV, considering cost and patient satisfaction. Published by Elsevier Inc.

    This study aimed to present our clinical experience using a prolonged tissue expansion technique and a Medpor framework for congenital microtia reconstruction. Auricular reconstruction was performed in 3 surgical stages. In the first surgical stage, a 60-mL custom kidney-shaped tissue expander is placed subcutaneously in the retroauricular mastoid region. The tissue expander is then serially expanded to maximum volume plus 30%. The tissue expander is then left fully expanded for 3 to 6 months. In the second surgical stage, the tissue expander is removed and a single-piece Medpor implant is placed and covered entirely by the expanded skin flap, without application of a fascial flap or skin graft. In the third stage, we perform an excision of the remnant microtic ear. A total of 15 patients were included with postoperative follow-up ranging from 6 months to 5 years. The draped soft tissue envelope was thin enough to show the reconstructed ear with excellent definition of the framework. Complications in this series included 1 case of partial implant exposure. The use of a Medpor framework after prolonged tissue expansion provides a well-defined, well-projected ear with robust soft tissue coverage. The expanded skin envelope with this method provides sufficient retroauricular non-hair-bearing skin tissues for draping the framework without the need for temporoparietal fascial flap or skin grafting. This alternative surgical method reduces surgical time and morbidity, and facilitates an aesthetic, natural-appearing reconstruction of the auricle.

    The great auricular nerve (GAN) originates from the cervical plexus at the levels of C2 and C3, supplying sensation to the skin overlying the lower aspect of the pinna and angle of the mandible. The GAN can be injured during many procedures in the head and neck, resulting in a significant negative impact on the patient's quality of life. There are no reliable anatomic studies of GAN in the area where it is most likely to get injured. To determine the GAN relationship to the posterior border of the platysma and the external jugular vein (EJV). Patients undergoing neck dissections were included in the study. Measurements were taken between the posterior border of the platysma relative to the nearest edge of the EJV and the GAN. The distance between the GAN and the EJV was also noted. The posterior borders of the platysma and EJV are found, on average, 0.08 cm away from each other, and the free edge of the platysma was most often posterior to the EJV. The distance from the platysma to the GAN was, on average, 0.60 cm. The distance between the EJV and the GAN was 1.17 cm. We have added a safe, reliable, and surgically relevant technique to the head and neck surgeon's armamentarium for identifying the GAN and avoiding attendant injury with long-term debilitating neurologic sequelae.

    Human myiasis is the parasitism of human tissues by fly larvae. Diagnoses are based on clinical pattern of tissue damage and presence of insect stages. Herein, a case myiasis is described in a seven-year-old female child. She presented with fever associated with abscessed scalp lesions containing exposed larvae. Severe pediculosis was also observed. The patient was hospitalized and treated with clindamycin, gentamicin (for bacterial secondary infections) and ivermectin (treatment for lice) after which the patient showed clinical improvement and was discharged four days later. Since human myiasis can be caused by a number of different species, larvae were collected from the patient and identified as those of Cochliomyia hominivorax (Diptera: Calliphoridae). Because other cases of coinfestation of flies and lice are on record, health workers are to be alerted about the possible pediculosis-myasis risk.

  20. 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.

    The authors demonstrate the direct, noninvasive and time resolved imaging of functional frog auricular fibers by ionic contrast terahertz (ICT) near field microscopy. This technique provides quantitative, time-dependent measurement of ionic flow during auricular muscle electrical activity, and opens the way of direct noninvasive imaging of cardiac activity under stimulation. ICT microscopy technique was associated with full three-dimensional simulation enabling to measure precisely the fiber sizes. This technique coupled to waveguide technology should provide the grounds to development of advanced in vivo ion flux measurement in mammalian hearts, allowing the prediction of heart attack from change in K+ fluxes.

    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.

    To investigate the effect of auricular acupuncture therapy (AAT) and standardized acupoints on sleep parameters among people with insomnia. A single-blind, randomized pilot study where the treatment group AAT on active points and the control group received AAT on sham points during a 4-week treatment period. Participants were recruited from the Acupuncture Outpatient Clinics in the General Hospital of People's Liberation Army. In all, 125 patients were included in the study, with 63 in treatment group and 62 in control group. Sleep parameters were obtained by using the Pittsburgh Sleep Quality Index (PSQI). (1) Significant improvement in the PSQI total score and seven components score including sleep quality, time on falling asleep, sleeping time, efficiency and disorder of sleep, hypnotic and daytime functional disorder after treatment in both treatment group and control group (P<0.01). (2) After treatment, there was a statistically significant difference seen in the PSQI total score and six components score (P<0.01) except for hypnotic between the two groups. There were statistically significant differences in the rank differential value of total score and seven components of two groups (P<0.01). (3) There were statistically significant differences in the mean rank of PSQI seven components using Mann-Whitney test (P<0.01). Evidence was found to support the hypothesis that AAT played an effective role in improving the quantity and quality of sleep in those subjects with insomnia. A standardized AAT might help the treatment of insomnia, especially when combined with other treatments as psychological and behavioral therapies.

    Preoperative anxiety has become more frequent in preoperative patients and can bring negative impact on operation outcomes. Many studies have reported the effect of body acupuncture in reducing anxiety syndromes. The aim of this study is to compare the treatment effect of body acupuncture and auricular acupuncture in preoperative patients with preoperative anxiety. Thirty five elective ambulatory surgery patients were selected in the randomized and blinded trial. Subjects were randomly categorized in two intervention groups, the body acupuncture group who received acupuncture in the special points of body, and the auricular acupuncture group who received ear acupuncture. Zung Self-Rating Anxiety Scale (SAS) was used before and after the study. For the auricular acupuncture group, the mean score of SAS was 57.57 ± 8.22 before the intervention and 46.32 ± 6.37 afterward. For the body acupuncture group, the SAS score was 55.39 ± 5.41 and 44.82 ± 6.76 before and after the intervention, respectively. For both groups, the difference between pre- and post-treatment scores reached the significant level (p = 0.00). Both auricular and body acupuncture treatment methods were effective in decreasing anxiety in preoperative patients.

    Three-dimensional computer tomography (3D-CT) was performed in 60 patients with auricular anomaly to determine the site and severity of deformity in the hemifacial microsomia. Auricular anomaly, underdevelopment and malposition of the cranium, temporo-mandibular joint, zygoma, maxilla and mandible were observed in almost all of the patients; however, the severity of these malformations varied from patient to patient. Regarding severest deformity, there were positional differences among patients. According to impairment sites, hemifacial microsomia fell into the following five types: (1) cranium type, (2) maxillary alveolar process type, (3) localized mandibular ramus type, (4) overall mandibular type, and (5) complex type (combination of the aforementioned types). Facial asymmetry accompanied by auricular anomaly was associated with various pathologic conditions. The temporomandibular joint was often deviated towards the anteromedial side for localized mandibular ramus type and overall mandibular type. Posterial deviation was predominant for cranium type. In patients with hemifacial microsomia of the cranium type associated with protrusion mainly in the occipital region on the affected side, deformity was considered attributable to underdevelopment of the temporal bone and delay in closure of the temporo-occipital suture. The deformity for cranium type may be defined as the second branchial syndrome. In conclusion, hemifacial microsomia have various deformities and may fall into five categories. Craniofacial microsomia and hemi-auriculo-temporo-mandibular dysplastic syndrome give a more precise concept for auricular anomaly. (N.K.).

    The caring relationship between individual health care providers and patients is a critical component of healing. However, caring can result in physical, emotional, psychological, and spiritual symptoms in providers that can interfere with their capacity to enter into these relationships. The aim of this study was to evaluate whether auricular acupuncture is an effective tool for reducing health care provider stress and anxiety and, second, to determine if auricular acupuncture impacts provider capacity for developing caring relationships with patients. Preintervention and postintervention surveys were evaluated to see if auricular acupuncture was associated with changes in State-Trait Anxiety Inventory (STAI), Professional Quality of Life, and Caring Ability Inventory scores. Compared with baseline, participants had a significant reduction in state anxiety (STAI), trait anxiety (STAI), burnout, and secondary traumatic stress scores (Professional Quality of Life). Significant increases were noted in courage and patience, 2 dimensions of the Caring Ability Inventory. Auricular acupuncture is an effective intervention for the relief of stress/anxiety in providers and supports heightened capacity for caring.

Autonomic imbalance demonstrating an increased sympathetic activity and a reduced parasympathetic activation is involved in the development and progress of epileptic seizures. Activation of the parasympathetic nervous system such as vagus nerve stimulation has been used for the treatment of intractable epilepsy. Here, we propose that auricular acupuncture may suppress epileptic seizures via activating the parasympathetic nervous system.

    Full Text Available Objective: This study aims to determine the association between auricular signals and the risk factors of metabolic syndrome (MS. Methods: A case-control study with an equal number of cases and controls matched by age group and gender was conducted. A total of 204 participants were recruited. Patients were verified as having MS based on the International Diabetes Federation (IDF criteria. Auricular assessment was conducted in the following sequence: visual inspection, electrical skin resistance test (ESRT, and pressure pain test (PPT. Results: MS+ patients tend to have much more oily auricle complexion than the controls. The ‘endocrine’ (right of the participants with MS indicated a significantly higher electrical conductivity compared to that of the controls. The MS group participants experienced significant tenderness on the ‘heart’ and ‘endocrine’ acupoints. A number of auricular signals were also associated with the risk factors of MS, including age, gender, smoking status, family history of diabetes, and comorbid illnesses. Both the ‘heart’ and ‘endocrine’ acupoints showed the highest sensitivity to tenderness (60.8%, followed by the ‘endocrine’ (59.8% and ‘pancreas and gallbladder’ (55.9%. Conclusions: The results of this study suggest that electrical conductivity and tenderness of a number of auricular points, including the ‘heart’, ‘pancreas and gall bladder’, and ‘endocrine’, are associated with MS and its risk factors. Further investigations with a larger sample size could be conducted to verify the value of these auricular signals on MS risk prediction so that this method can be used as an early screening method for the population with a high MS risk.

    Full Text Available Background: hypertension is one of the main cardiovascular risk factors, so its control improves the life expectancy of patients.Objective: to assess the effects of a treatment combining medication with auricular therapy and phyto-therapy in hypertensive patients assisted at the health area of ”Romárico Oro” Polyclinic, in Puerto Padre, Las Tunas province.Methods: an intervention study was carried out in 68 hypertensive patients of the health area of “Romárico Oro” Polyclinic in Puerto Padre from April, 2013 to April, 2014. The patients were distributed at random into two equal groups; the first received medication combined with auricular therapy and phyto-therapy, while the second one received only medication. The statistical analysis was done by means of Statistic system, t-student and Chi-Square tests were used and p< or =0.05 was considered as level of statistical significance.Results: by the end of the intervention, 73, 53% of the patients of the group with the combination of drug treatment and auricular therapy and phyto-therapy were controlled. In this group, the diastolic filling pressure diminished to 2, 2 mm Hg and the systolic gradient to 3, 66 mm, regarding the group treated only with drugs. Only one patient, representing the 2, 94% showed adverse reaction to the natural and traditional treatment.Conclusions: the combination of medication with auricular therapy and phyto-therapy proved to be effective, corroborated by a significant decrease of quantity of crisis, diastolic and systolic filling pressure values and increase of number of patients with their disease controlled; the report of only one complication shows the innocuousness of the auricular therapy and phyto-therapy treatment.

The experiment was conducted in climatized chamber regulated at 30ºC, 65±10% RH and 14 hour photophase. No significant difference was observed on average duration of first and second larval instars berween the two morphotypes, taking into account not only the conventional interpretation for the reading of different development phases of the larval stages (morphotype 1:11.0 and 11.9 hours and morphotype 2:11.7 and 12.7 hours for first and second instars, respectively, but also the reading made through the interpretation preconized by Snodgrass & Hinton (morphotype 1:10.3 and 9.6 hours and morphotype 2:9.8 and 10.8 hours for the first and second instars, respectively. The incubation period was significantly longer for eggs posited by females from non-pigmented larvae.

    Myiasis is usually caused by flies of the Calliphoridae family, and Cochliomyia hominivorax is the etiological agent most frequently found in myiasis. The first case of myiasis in a diabetic foot of a 54-year-old male patient in Argentina is reported. The patient attended the hospital of the capital city of Tucumán Province for a consultation concerning an ulcer in his right foot, where the larval specimens were found. The identification of the immature larvae was based on their morphological characters, such as the cylindrical, segmented, white yellow-coloured body and tracheas with strong pigmentation. The larvae were removed, and the patient was treated with antibiotics. The larvae were reared until the adults were obtained. The adults were identified by the setose basal vein in the upper surface of the wing, denuded lower surface of the wing, short and reduced palps, and parafrontalia with black hairs outside the front row of setae. The main factor that favoured the development of myiasis is due to diabetes, which caused a loss of sensibility in the limb that resulted in late consultation. Moreover, the poor personal hygiene attracted the flies, and the foul-smelling discharge from the wound favoured the female's oviposition. There is a need to implement a program for prevention of myiasis, in which the population is made aware not only of the importance of good personal hygiene and home sanitation but also of the degree of implication of flies in the occurrence and development of this disease.

    Infestations caused by fly larvae (Myiasis) have been observed in patients with risk factors and in tropical zones. The aim of our study was to describe the clinical and epidemiological aspects and the risk factors associated with the occurrence of obligatory myiasis, as well as the therapeutic approach to patients. We identified the cases of myiasis diagnosed in two referral hospitals in northern Peru from January 2012 to December 2015 and included patients in whom larval development and a compatible clinical profile were observed. Epidemiological, clinical, analytical, diagnostic, therapeutic, and follow-up data were collected from clinical files. Nine clinical cases were compatible with a diagnosis of myiasis; of these, two were pediatric patients, one was a middle-aged adult, and six were elderly patients. Four of the nine patients were male. The identified species were Dermatobia hominis and Cochliomyia hominivorax. The therapeutic approach included antiparasitic therapy with ivermectin, antibacterial, and in some cases, anti-inflammatory drugs. Dermatobia hominis and C. hominivorax are the predominant species causing myiasis in northern Peru.

    The screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), is one of the most devastating arthropod pests of livestock in the Western Hemisphere. Early instars are very difficult to distinguish morphologically from several closely related blow fly species. Random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) markers were developed for identifying C. hominivorax from other wound inhabiting species. Forty decameric primers were screened; nine showed clear reproducible RAPD profiles suitable for distinguishing all life stages of C. hominivorax from 7 other species, including C. macellaria (Fabricius). The results from RAPD-PCR with field-collected samples of unknown first instars agreed with morphological identification that the samples were not C. hominivorax. Three different primers showed DNA polymorphisms (intraspecific) for samples originating from Mexico, Costa Rica, Panama, Jamaica, and Brazil. Therefore, RAPD-PCR may be useful for determining the geographic origin of C. hominivorax samples. Comparing products from these primers, used with known and unknown screwworm samples from an outbreak in Mexico, clearly showed that the outbreak did not originate from the mass rearing facility. Accurate identification of suspected C. hominivorax samples is possible using RAPD-PCR. Further development to identify the geographic origin of samples would benefit the ongoing surveillance programs against C. hominivorax and the decision process during suspected outbreaks of this important pest.

    Full Text Available Cochliomyia macellaria is of medical and veterinary interest, because it is an enteropathogen vector and causes secondary miyasis, and low cost diets are needed that maintain rearing quality of this species. The objective of this study was to assess a chicken gizzard diet, compared to beef, in the post-embrionic development of C. macellaria. Forty neolarvas (3rd generation were transferred to 80g diets (four replications/treatment. The body mass of the mature larvae was recorded and the larvae were transferred to test tubes, kept at T 30ºC day/28ºC night, RH 70±10%, 12 hours light period, and observed daily. There was a significant difference between the body mass of larvae reared on the chicken gizzard (0.067g and beef (0.062g diets. There was no significant difference between the mean duration in days of the larval (4.00; 4.17, pupa (4.09; 4.04 and neolarva to adult (8.07 and 8.16 stages based on the gizzard and beef diets, respectively. The mean larval, pupa and total viability (> 85% did not differ statistically by the Student’s t test (at 5% significance. There was no deviation in the sex ratio and no abnormality was observed in the adults. The results suggest that the chicken gizzard diet is an efficacious and cheap alternative for rearing C. macellaria in the laboratory.

    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.

    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 established surgical methods of external ear reconstruction using autogenous tissue represent the current state of the art. Because of the limited possibilities for shaping conventional harvested autogenous rib cartilage, the cosmetic results of auricular reconstruction are frequently unsatisfactory. Tissue engineering could represent an alternative technique for obtaining a precisely shaped cartilage implant that avoids donor site morbidity and unsatisfactory cosmetic results. In this study, the reliability and quality of a tissue-engineering model for the manufacture of auricular-shaped human cartilage implants was investigated, focusing on the feasibility of the manufacturing process and the in vivo and in vitro maturation of an extracellular cartilage-like matrix. Implants were molded within an auricular-shaped silicone cylinder, and human nasal septal chondrocytes crosslinked by human fibrin within bioresorbable PGLA-PLLA polymer scaffolds were used. After an in vitro incubation of up to 6 weeks, defined fragments of the prefabricated auricular-shaped construct were implanted subcutaneously on the backs of nude mice for at least 6 to 12 weeks ( n=7). Scaffolds without cell loading served as controls. Macroscopic and histochemical examination after 3 and 6 weeks in vitro showed a solid compound of homogenously distributed chondrocytes within the polymer scaffold, leading only to a limited pericellular matrix formation. Analysis after 6 and 12 weeks of in vivo maturation demonstrated a solid tissue compound and neocartilage formation with the presence of cartilage-specific matrix components. Implants obtained shape and size during the entire period of implantation. The model of cartilage implant manufacturing presented here meets all biocompatible requirements for in vitro prefabrication and in vivo maturation of autogenous, individually shaped cartilage transplants.

    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.

    The purpose of this study was to examine the effects of auricular acupressure on reducing obesity in adult women with abdominal obesity. The study design was a non-equivalent control group pretest-posttest design. Participants were 58 women, aged 20 years or older, assigned to the experimental group (n=30) or control group (n=28). Auricular acupressure using vaccaria seeds was administered to the experimental group. The sessions continued for 8 weeks. Outcome measures included body weight, abdominal circumference, and body mass index, body fat mass, body fat percentage, triglyceride, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and serum glucose. Women in the experimental group showed significant decreases in body weight (t=6.19, p<.001), abdominal circumference (t=4.01, p<.001), and body mass index (t=2.58, p=.006) after 8 weeks compared with those in the control group. Results show that auricular acupressure using vaccaria seeds was effective in decreasing body weight, abdominal circumference, body mass index, and triglyceride levels in adult women with abdominal obesity.

    To compare the differences in the therapeutic effect on child amblyopia between auricular point sticking therapy and routine complex treatment. Two hundreds and thirty cases of amblyopia were randomly divided into an observation group and a control group, 120 cases (212 eyes) were in the observation group and 110 cases (194 eyes) were in the control group. The observation group was treated with auricular point sticking therapy. The main points were Yan (eye), Shenmen, Gan (liver), Pi (spleen) and Shen (kidney), etc. The control group was treated with routine complex treatment, such as wearing glasses, shade therapy and family refined performance therapy. The changes of vision were observed after treatment in the two groups. The follow-up was 3 years. The effective rate was 81.0% (64/79) in the observation group of ametropic amblyopia and 52.2% (36/69) in the control group. The effective rate was 73.1% (49/67) in the observation group of anisometropic amblyopia and 47.7% (31/65) in the control group. The effective rate was 71.2% (47/66) in the observation group of strabismic amblyopia and 45.0% (27/60) in the control group. The therapeutic effect of the observation group was superior to that of the control group (all P < 0.05). Auricular point sticking therapy can obviously improve child visual acuity with simple manipulation.

    In this study we investigated the histological, biochemical, and integrative features of the neocartilage using swine auricular chondrocytes photoencapsulated into two poly(ethylene glycol) dimethacrylate (PEGDM) copolymer hydrogels of a different degradation profile: degradable (PEG-4,5LA-DM) and nondegradable (PEGDM) macromers in molar ratios of 60:40 and 70:30. Integration of the engineered tissue with existing native cartilage was examined using an articular cartilaginous ring model. Experimental group samples (total n = 96) were implanted subcutaneously into nude mice and harvested at 6, 12, and 18 weeks. Nonimplanted constructs (total n = 16) were used as controls for quantification of DNA, glycosaminoglycan, and hydroxyproline. Histologically, neocartilage resembled both the cellular population and composition of the extracellular matrix of the native swine auricular cartilage. DNA content demonstrated that the photoencapsulated chondrocytes were capable of survival and proliferation over time. Both glycosaminoglycan and hydroxyproline contents appeared higher in the neotissue, which was supported by less degradable PEGDM hydrogel. Integration of neocartilage with surrounding native cartilage improved with time, resulting in the development of tight integration interface. PEGDM copolymer hydrogels can support in vivo chondrogenesis by photoencapsulating auricular chondrocytes. PMID:20695772

    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.

    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.

    Full Text Available Purpose. To assess surgical outcomes of lower lid reconstruction surgery using auricular conchal tissue. Methods. This prospective study included 20 patients that underwent reconstructive lower lid surgery using autologous auricle chondral-perichondral graft tissue. Auricle tissue was used to provide adequate support and protection with similar conjunctiva tarsal structures on overlying soft tissues in patients with pathologic inferior lid tissue loss requiring reconstructive surgery. Biopsies with histopathology and cytology analysis were taken after 1 year. Cytology analysis using CK19 was used to confirm newly formed conjunctiva overlying the graft. Results. All patients showed no graft rejection. Surgical outcomes were generally good, with minimal or no ocular complications. 16 of 20 patients had excellent results, showing good lid symmetry and esthetics, minimal auricular discomfort, patient satisfaction and proper lid function. Surgical outcomes were highly dependent on proper post-op conjunctiva formation. All patients were positive for CK19, thus indicating proper conjunctiva tissue formation. Conclusions. Lower lid reconstruction surgery using auricular chondral-perichondral conchal tissue is a good alternative in patients with neoplastic lesions. Autologous chondral-perichondral tissue provides good functional and mechanical support in the reconstructed lid, thus reducing the risks of ectropion and corneal exposure and ensuring a protected ocular surface.

    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.

    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.

    Forensic entomologists often rely on development data associated with a given species to estimate when it colonized human or other vertebrate remains. In most instances, these development studies are based on single species reared in isolation in the laboratory. This study examined the impact of excretions and secretions (ES) associated with third-instar Chrysomya rufifacies (Macquart), a predator, on the development of its prey, Cochliomyia macellaria (F.). Not surprisingly, Ch. rufifacies ES did not impact the development of first- or second-instar C. macellaria, which are typically not preyed on by Ch. rufifacies. However, development of third-instar C. macellaria, which do experience predation, was impacted. First, larvae were longer than those in the control (deionized water, dH2O). Filtering the ES and removing the associated bacteria and byproducts >0.2 µm dampened the previous impact observed by the unfiltered ES on third-instar C. macellaria. Second, third-instar C. macellaria treated with unfiltered ES completed pupariation 8 h quicker than the controls. Filtering the ES lessened this effect by 50%. And finally, third-instar C. macellaria treated with filtered or unfiltered Ch. rufifacies ES reached adulthood ∼5 h faster than controls treated with dH2O. In summary, these data have large ramifications for forensic entomology, as multiple species being present on decomposing remains is not uncommon. Understanding the impact of associated ES produced by interspecific cohorts on associated development could lead to more precise estimates of the minimum postmortem interval for forensic investigation of decomposing remains. © The Authors 2017.

    Larvae (maggots) of Cochliomyia hominivorax, the New World Screwworm fly, are voracious consumers of living flesh that have a negative economic impact by decreasing productivity, predisposing to other pathogens, and, in severe cases, causing death of domestic livestock. Screwworm caused extensive financial losses to the livestock industry in North America prior to its eradication. Sterile insect technique (SIT) was used to eradicate screwworm throughout North and Central America and continues to be the main tool to control it in eastern Panama. The goal of this study was to evaluate the temporal and spatial trends of screwworm myiasis cases reported in the Province of Darien and Comarca Embera (border with Colombia), Panama, from 2001 to 2011. We hypothesized that screwworm cases would vary seasonally and be spatially clustered near Colombia as a result of effective eradication strategies in Panama and the presence of an autochthonous population of flies in western Colombia. Temporal and spatial data were retrieved from COPEG-USDA records (Panama) and analysed by anova, Ripley's K function, discrete Poisson spatial statistic scan and Getis-Ord Gi*. No significant temporal trend was found, but cases were spatially distributed in four clusters. One cluster of cases occurred from 2001 to 2003 and was considered a focal temporal and spatial cluster. One cluster occurred in 2001 and 2007 indicating more rare outbreaks in an area with fewer cattle. The two remaining clusters contained cases from 2004 to 2011 and 2001 to 2011 suggesting regular breaks in the control barrier due to occasional failures of the SIT programme, difficulties implementing border quarantine strategies, livestock smuggling or the movement of infested wildlife. © 2015 Blackwell Verlag GmbH.

    The New World Screwworm (NWS), Cochliomyia hominivorax, was eradicated from the USA, Central America to Panama, but in most tropical regions of Latin America, the NWS is still a serious threat to livestock, provoking estimated annual losses of US$ 1.8 billion in Brazil. Between January and May 2009, a pilot-project was performed at the Brazil-Uruguay border. As the results were positive, novel regional Area-Wide Integrated Pest Management projects are being planned. To set a mass-rearing center based in South America is strategic when considering long-term programs. In partnership with CENA/USP and the Biofactory MOSCAMED Brazil, a project to produce sterile NWS started on 2009. The project aimed to maintain a colony of a regional NWS strain, to develop a mass-rearing system and a sterilization protocol by X rays, and to study the sterility induction in regional strains. A colony was successfully established. The adults were kept in cages and fed on a diet (honey and spray dried egg). The larvae were reared in a medium made of spray dried blood, spray dried egg, milk, water, formalin and Ecogel. Egg hatch has been of 80 {+-} 10%. From F{sub 1} to F{sub 22}, the total amount of pupae produced was about 38 L ({approx} 315,400 pupae). The mean adult emergence and sex ratio were 86.7 {+-} 3% and 0.59 {+-} 0.08 respectively. The mean pupal weight was 47.1 {+-} 1.7 mg. The estimated X ray doses to induce 99% sterility in males and females were 43.7 Gy and 47.5 Gy, respectively. To produce 1.5 L of pupae, the current cost is about US$ 15.00. (author)

    Larval therapy (LT) is the application of carrion flies (Diptera) sterile larvae on chronic or infected wounds to promote or accelerate the healing process. High cost and the development of resistance by certain groups of pathogenic bacteria to these drugs encouraged the resurgence of LT, currently used in approximately 20 countries and more recently in Brazil. This study evaluated the behavior and larval density of Cochliomyia macellaria F. (Calliphoridae), one of the most appropriate species for debridement of injuries with necrotic tissue. Tegumentar lesions were induced in Wistar rats by subcutaneously application of 0.2 ml of a 1:4 hydrochloric acid and sterile distilled water in the dorsal region. Five experimental groups were set up: (LT 5) treatment with 5 larvae/cm(2); (LT 15) 15 larvae/cm(2); (LT 25) 25 larvae/cm(2); (DEB) mechanical debridement, and (NUL) animals that did not receive any treatment. In the LT groups, larvae used were sterilized with sodium hypochlorite (NaClO) and maintained for 12 h in the lesions. The healing process was assessed qualitatively (macroscopically and microscopically) and quantitatively (time interval to complete healing). It was observed that the immature fed only on necrotic tissue, thus C. macellaria is an excellent candidate for use in LT. There was no significant difference in healing time between experimental groups. However, it was observed that in LT 25, there was greater vascularization in tissues when compared to the other treatments. The mechanisms involved in this process are unknown, but it is evident that the larvae have an important role in modulating the host immune response. It is essential that future applications of larval therapy consider using a higher density of larvae (minimum of 25 larvae/cm(2)) than is currently recommended.

    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

  18. Vasoconstrictive Responses by the Carotid and Auricular Arteries in goats to Ergot Alkaloid Exposure

    Aiken, Glen; Flythe, Michael

    2014-11-01

    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. Seven, rumen fistulated goats were fed ad libitum orchardgrass (Dactylis glomeratia) hay and ruminally infused with endophtye-free seed (E-) for a 7-day adjustment period. Two periods followed with E- and endophyte-infected (E+) seed being randomly assigned to the 2 goat groups in period 1 and then switching treatments between groups in period 2. Infused E+ and E- seed were in equal proportions to the hay such that concentrations of ergovaline and ergovalanine were 0.80 µg per g dry matter for the E+ treatment. Cross-sections of both arteries were imaged using Doppler ultrasonography on days 0, 2, 4, 6, 8, and 12 in period 1 and on days 0, 1, 2, 3, 6, 7, and 9 in period 2. Differences from average baseline areas were used to determine presence or absence of alkaloid-induced vasoconstriction. Carotid arteries initiated constriction on imaging day 2 in both periods, and auricular arteries initiated constriction on imaging day 2 in period 1 and on day 6 in period 2. Luminal areas of the carotid arteries in E+ goats were 46% less than baseline areas in both periods after vasoconstriction occurred, whereas auricular arteries in E+ goats were 52% less than baseline areas in period 1 and 38% in period 2. Both arteries in E+ goats in period 1 relaxed relative to baseline areas by imaging day 2 after they were switched to the E- treatment. Results indicated that goats can vasoconstrict when exposed to ergot alkaloids that could disrupt their thermoregulation.

    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. Seven, rumen fistulated goats were fed ad libitum orchardgrass (Dactylis glomeratia hay and ruminally infused with endophtye-free seed (E- for a 7-day adjustment period. Two periods followed with E- and endophyte-infected (E+ seed being randomly assigned to the 2 goat groups in period 1 and then switching treatments between groups in period 2. Infused E+ and E- seed were in equal proportions to the hay such that concentrations of ergovaline and ergovalanine were 0.80 µg per g dry matter for the E+ treatment. Cross-sections of both arteries were imaged using Doppler ultrasonography on days 0, 2, 4, 6, 8, and 12 in period 1 and on days 0, 1, 2, 3, 6, 7, and 9 in period 2. Differences from average baseline areas were used to determine presence or absence of alkaloid-induced vasoconstriction. Carotid arteries initiated constriction on imaging day 2 in both periods, and auricular arteries initiated constriction on imaging day 2 in period 1 and on day 6 in period 2. Luminal areas of the carotid arteries in E+ goats were 46% less than baseline areas in both periods after vasoconstriction occurred, whereas auricular arteries in E+ goats were 52% less than baseline areas in period 1 and 38% in period 2. Both arteries in E+ goats in period 1 relaxed relative to baseline areas by imaging day 2 after they were switched to the E- treatment. Results indicated that goats can vasoconstrict when exposed to ergot alkaloids that could disrupt their

    The utility of the nonsurgical correction of congenital auricular deformities by ear molding and splinting has been previously established. Occasionally, its application cannot be easy, and the later collaboration of the parents is necessary. We report a new method of splinting that simplifies the procedure. prospective, case series. Twenty ears in 15 patients between 7 and 60 days of age (average 22 days) were treated. They were 12 prominent ears, 4 Stahl's ears, 2 lop ears, 1 Crinkled ear, and 1 case of increase of antihelix folder. Cotton impregnated with 2-Octyl-Cyanoacrylate is placed as splint for 6 weeks. The bilateral application lasted less than 5 minutes, end there were no spills to the external auditory canal. The splint was given off to the 2 weeks, and a second procedure was necessary in all the cases. There were no dermatitis or skin ulcers. The treatment was successful in 11 cases, partial improvement in 3, poor correction in 4, and recurrence in 2. The splint therapy is an easy nonsurgical method for the treatment of congenital auricular deformities that applied during the first weeks of life provides good aesthetic results in more than 50% of the patients.

    The aim of this study was to evaluate the technical feasibility and safety of robot-assisted modified radical neck dissection (MRND) for head and neck cancer patients with a clinically node-positive neck. The cases of 10 head and neck cancer patients who underwent unilateral therapeutic robot-assisted MRND by post-auricular facelift approach were analyzed. The robot-assisted MRND was completed successfully in all patients without any conversion to conventional neck dissection. The mean number of lymph nodes removed was 36.7±8.6. The mean duration of surgery for robot-assisted MRND was 274±65min (range 175-395min). Transient marginal nerve palsy occurred in two patients and partial necrosis of the skin flap occurred in one patient. In terms of cosmetic satisfaction, 70% of patients were very satisfied or satisfied with postoperative cosmesis. In conclusion, robot-assisted MRND by post-auricular facelift approach is technically feasible and safe in selected patients with head and neck cancer, and yields excellent postoperative cosmesis.

    Full Text Available Auricular acupuncture has been described in ancient China as well as Egypt, Greece, and Rome. At the end of the 1950s, ear acupuncture was further developed by the French physician Dr. Paul Nogier. The goal of this study was to develop a new system for ear acupressure (vibration stimulation and to perform pilot investigations on the possible acute effects of vibration and manual ear acupressure on heart rate (HR, heart rate variability (HRV, pulse wave velocity (PWV, and the augmentation index (AIx using new noninvasive recording methods. Investigations were performed in 14 healthy volunteers (mean age ± SD: 26.3±4.3 years; 9 females, 5 males before, during, and after acupressure vibration and manual acupressure stimulation at the “heart” auricular acupuncture point. The results showed a significant decrease in HR (≤0.001 and a significant increase in HRV total (=0.008 after manual ear acupressure. The PWV decreased markedly (yet insignificantly whereas the AIx increased immediately after both methods of stimulation. The increase in the low-frequency band of HRV was mainly based on the intensification of the related mechanism of blood pressure regulation (10-s-rhythm. Further studies in Beijing using animal models and investigations in Graz using human subjects are already in progress.

    Measurement of body temperature is a routine part of the clinical assessment of a patient. However, this procedure may be time-consuming and stressful to most animals because the standard site of temperature acquisition remains the rectal mucosa. Although an increasing number of clinicians have been using auricular temperature to estimate core body temperature, evidence is still lacking regarding agreement between these two methods in cats. In this investigation, we evaluated the agreement between temperatures measured in the rectum and ear in 29 healthy cats over a 2-week period. Temperatures were measured in the rectum (using digital and mercury-in-glass thermometers) and ear once a day for 14 consecutive days, producing 406 temperature readings for each thermometer. Mean temperature and confidence intervals were similar between methods, and Bland-Altman plots showed small biases and narrow limits of agreement acceptable for clinical purposes. The interobserver variability was also checked, which indicated a strong correlation between two near-simultaneous temperature readings. Results are consistent with auricular thermometry being a reliable alternative to rectal thermometry for assessing core body temperature in healthy cats.

    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 Study Objectives. To examine the stimulation effect of auricular magnetic press pellet therapy on older female adults with sleep disturbance as determined by polysomnography (PSG. Design. Randomized, single-blind, experimental-controlled, parallel-group. Setting. Community. Participants. Twenty-seven older female adults with sleep disturbance according to the Pittsburgh Sleep Quality Index (PSQI >5 for at least 3 months were recruited. Participants were screened by both the Hospital Anxiety and Depression Scale (HADS and the Mini-Mental State Examination (MMSE, as well as polysomnography prior to randomization. Interventions. All eligible participants were randomly allocated into the experimental or control group. Both groups were taped with magnetic press pellet on auricular points for 3 weeks. The experimental group was treated by applying pressure on the magnetic press pellets 3 times per day while no stimulation was applied on the control group. Measurements and Results. Both groups were measured by PSG and PSQI at the beginning of the study and 3 weeks after the study. Both groups showed improvements on PSQI scores compared to the baseline. One-way analysis of covariance adjusted for baseline scores showed that significant improvements of PSG-derived sleep parameters, such as sleep efficiency, were found in the experimental group. However, no significant differences between groups were observed in the proportion of sleep stages with the exception of Stage 2. Conclusions. Auricular therapy using magnetic pellets and stimulation by pressing was more effective in improving the sleep quality compared to auricular therapy without any stimulation.

    High-flow arteriovenous malformations (AVMs) with a dominant outflow vein (DOV) remain difficult for ethanol embolotherapy, but improved technology and experience of detachable coils allows for the treatment of some of these AVMs with satisfactory results. A single-center experience and evaluation of technical and clinical safety, and effectiveness of electrolytically detachable coil (EDC)-assisted DOV occlusion for ethanol embolization of high-flow auricular AVMs, which has some advantages over conventional coils because of its controlled deployment, reposition, and removal is reported. From November 2010 to June 2013, 40 consecutive patients with auricular AVMs underwent staged ethanol embolizations, of which nine patients' auricular AVMs with a DOV who had undergone ethanol embolization of high-flow auricular AVMs in combination with EDCs-assisted DOV occlusion were retrospectively evaluated. Clinical follow-up (range, 5-29 months; mean, 15.1 months) was completed in all patients, and results from imaging follow-up (range, 7-25 months; mean, 14.7 months) were available from the last treatment session in six patients. Therapeutic outcomes were determined by evaluating the clinical outcome of symptoms and signs, as well as the degree of devascularization at follow-up arteriography. Twenty-eight ethanol embolizations and nine EDC-assisted DOV occlusions were performed in nine patients. Seventeen EDCs were used in nine patients. Five (55.6%) of the nine patients were cured, and four (44.4%) had partial palliation. One minor complication occurred in one of the nine patients. Transient hemoglobinuria occurred in six of nine patients in a total nine of the 28 procedures. There were no major complications. Ethanol embolization has the potential for cure in the management of high-flow auricular AVMs with the aid of occlusion DOV by EDCs with acceptable risk of minor and major complications.

    Few high-quality, large-scale, controlled trials comparing the effectiveness and safety of acupuncture,auricular acupuncture and combined acupuncture treatment for insomnia are available. To carry out a randomised, assessor-blinded, waitlist-controlled trial to test the superiority of combination treatment. After in-person and polysomnography screening, 224 subjects (mean age 53.4 years; 75.4% female) with DSM-5 insomnia disorder, who were free from major psychiatric disorders and with sleep-diary-derived sleep efficiency averaged over 1 week of acupuncture alone, acupuncture plus auricular acupuncture (combination treatment), or a waitlist in a 3:3:1 ratio. Standardised acupuncture and combination treatment were provided three times weekly for 3 weeks. The primary outcome was sleep-diary-derived sleep efficiency. Secondary outcomes included wrist actigraphy and self-reported scales on insomnia, anxiety and depression, fatigue, sleepiness and functioning. Assessments were conducted at baseline, 1 week, 4 weeks and 13 weeks after treatment. Participants on the waitlist were re-randomised to receive acupuncture or combination treatment after the second post-baseline assessment. There was no significant difference between acupuncture and combination treatment in the primary outcome and most secondary outcomes at all time points. However, both treatments were better than waitlist in reducing insomnia, anxiety/depressive symptoms and fatigue, and improving function. Within-group improvements were maintained at 13 weeks after treatment. Of 260 adverse events, 243 were mild (93.5%). Discontinuation due to adverse events was 2.1% and 3.1% for acupuncture and combination treatment, respectively. Limited by short-term treatment and follow-up, the attempt to augment acupuncture by auricular acupuncture was not supported. Acupuncture and combination treatment were safe and had mild hypnotic effects, which lasted for at least 13 weeks. NCT01891097; Results. © Article

Approximately, 30~40% of the cancer patients have said to be suffering from insomnia and half of them having chronic and severe insomnia at the same time. Insomnia caused cancer patients feel more pain, fatigue, depression and anxiety and it sometimes let the power to have the best of cancer pull down. Objective: To investigate how effective the auricular acupressure treatment to cancer patients suffering from insomnia. Methods: We recruited participants from East-West Cancer Center of Daejeon University. Finally, of the people whose age range from 20 to 75, 12 patients who got less than 40 points from the score of Oh's sleeping score (OSS were recruited. Single-blind, randomized pilot study was performed. The treatment group received auricular acupressure treatment (AAT on active points and the control group had received sham acupressure treatment (SAT for five times. Sleep parameters were checked by using OSS and numeric rating scale (NRS. We checked the scale everytime, both before and after treatment. We analyzed the data statistically by using independent T-test, paired T-test and analysis of variance (ANOVA test. (p<0.05 Results: Twelve cancer patients participated in this pilot study and there was no significant difference between control and treatment group. Only 7 of them had completed the whole treatment process, 4 patients of AAT group and 3 participants of SAT. The OSS of AAT group had increased from 34.0± 4.3 to 39.5±3.1 and that of SAT group had increased from 38.3±3.5 to 40.0±0.0. There was no significant difference between them. The NRS of AAT group had increased from 6.3±2.9 to 4.8±2.1 and that of SAT group had increased from 7.0±1.0 to 5.0±2.6. No significant difference was observed between them.

    The posterior auricular artery (PAA) is one of the branches of the external carotid artery, but is usually too small for use as a donor artery for middle cerebral artery (MCA) territory revascularization. An extremely unusual case of PAA-MCA anastomosis was performed in a patient requiring MCA territory revascularization because the superficial temporal artery (STA) parietal branch was absent and the PAA was large enough. A 65-year-old man developed mild motor weakness in the right extremities caused by multiple small infarctions. Single photon emission computed tomography (CT) revealed deterioration of the vascular reserve capacity in the left MCA area. Cerebral angiography showed severe stenosis in the C2 portion of the left internal carotid artery, absence of the parietal branch of the left STA, and a well-developed PAA extending to the parietal area. The patient underwent STA (frontal branch)-MCA and PAA-MCA double anastomosis, and has suffered no stroke or transient ischemic attack. The STA with no bifurcation is known as a rare variation. The PAA also occurs with size variations but well-developed PAA is thought to be extremely rare. PAA can be used as a donor artery for MCA territory revascularization if the vessel size is suitable. Preoperative evaluation of the anatomy is mandatory for harvesting the arteries.

    Full Text Available Cytarabine is an effective drug in the treatment of haematological malignancies. The therapy is associated with various complications. Frequencies of dermatological side-effects range from 2–72% and occur most commonly after high-dose regimens. Although most cutaneous reactions are mild and resolve spontaneously within several days, they may result in an increased risk of infection and alterations in comfort. In some cases, severe life-threatening reactions have been reported. Here we describe the case of a patient with acute myeloid leukaemia, who developed severe exceptional skin toxicity in terms of auricular oedema and palmar dyshidrotic eczema after the application of low-dose cytarabine. Re-administration of the drug resulted in reduced skin toxicity during further cycles of chemotherapy. Negative epicutaneous patch-testing supported the existence of cytarabine-provoked toxicity.

    Successful antiemesis contributes significantly to quality, safety, and patient satisfaction. Patients undergoing general anesthesia often experience postoperative nausea and vomiting (PONV). Acupressure offers a side effect-free alternative to common first-line antiemetics. Because the patient may perceive needle acupuncture as uncomfortable, acupressure is a desirable alternative for the prevention of PONV. This study was a randomized, prospective, double-blinded clinical trial investigating the effect of acupressure in patients with a history of PONV and motion sickness. The three auricular acupressure points chosen were shen men, point zero, and the subcortex point. Rescue treatment for PONV with 4 mg intravenous ondansetron was used if the patient reported persistent nausea. A blinded observer recorded antiemetic rescue data, and postoperative analgesic use was recorded over 24 hours. Nausea, vomiting, and retching were assessed in the post-anesthesia care unit (PACU). Using univariate analysis, we ruled out the null hypothesis of equal means as a function of intervention group (p = 0.001). Pair-wise comparisons revealed a difference between placebo and test groups (p = 0.000) and also sham and test groups (p = 0.033) where age (p = 0.048) and gender (p = 0.003) were significant covariates. Our data reveal that auricular acupressure significantly decreases nausea during the PACU stay and within the 24 hours postoperatively. It is not clear whether the intervention decreases nausea as a primary effect or as a secondary result by decreasing narcotic requirements. Also, perception of nausea may be in part subjective. This is evidenced by our results in which subjects who received sham points fared better than the placebo subjects.

    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.

    Auricular prostheses are artificial substitutes for facial defects. The retention of these has often been a problem. This study aimed to evaluate the mechanical behavior of 3 retained auricular prosthetic connections when submitted to a mechanical cycling test. Twelve samples with installed implants were obtained and divided into 3 groups according to their retention system with 4 samples in each group. I: bar-clip system; II: magnet system; and III: ball/o-ring system. Each of samples was submitted to the pull-out test during 3240 cycles (f = 0.5 Hz) to determine its tensile strength. The mechanical cycling test was performed using the servo-hydraulic machine MTS 810-Flex Test 40 (Eden Prairie, MN) that had a 2.5 mm shift at a 10 mm/s velocity. The retaining strength for each of the samples was obtained at 7 intervals. The tensile strength for the group retained by the bar-clip system (29.60 N) was higher with statistically significant difference (P < 0.05) when compared with the group retained by the ball/o-ring system (9.41 N) and magnets system (8.61 N) for all periods assessed. The ball/o-ring system showed loss of retention during the fatigue test (Kruskal-Wallis, chi-squared = 17.28; P < 0.01). The evaluated systems showed a tensile strength compatible with the clinical use and no fractures of the components were observed.

    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.

    Full Text Available In the present study we estimed the longevity and reproductive potential of Cochliomyia macellaria (Fabricius, 1775, in different densities of grouped pairs, as a function of time of collection. The study was divided into two phases and conducted in an incubator regulated at 27oC, 65±10% RH and 14 hours photoperiod. Forty and 20 pairs/replication were used, corresponding to the third and fourth generation originating from a laboratory colony. Egg masses were collected at 8:00 and 17:00 hours daily. The results obtained were influenced by the variables established. The ovipositing peak occurred 20 days after the emergence of females belonging to the third generation. This peak occurred earlier in fourth generation females, i.e., 11 days after imago emergence. These peaks corresponded to a total of 0,30 and 0,23g of egg masses, respectively. The survival curves for adults were estimated by the Weibull method.

    To assess agreement between carotid arterial pressure and auricular arterial, thoracic limb Doppler or thoracic limb oscillometric blood pressure measurements. Prospective experimental study. Six adult New Zealand white rabbits. Rabbits were anesthetized with isoflurane in oxygen at 1, 1.5 and 2 MAC on two separate occasions. Catheters in the auricular and the contralateral external carotid artery were connected to calibrated pressure transducers via non-compliant tubing. Inflatable cuffs of width equal to approximately 40% of the limb circumference were placed above the carpus on both thoracic limbs with a Doppler transducer placed distal to the cuff on one. Systolic (SAP) and mean (MAP) arterial blood pressure measurements were obtained at each dose, on each occasion. Agreement between measurement techniques was evaluated by repeated measures Bland Altman analysis with carotid pressure as the reference. Variation in bias over the measurement range was evaluated by regression analysis. Carotid MAP and SAP ranged from 20 to 65 mmHg and 37 to 103 mmHg respectively. Bias and 95% limits of agreement for auricular and oscillometric MAP were 7 (0-14) and -5 (-21-11) mmHg, respectively, and for auricular, oscillometric and Doppler SAP were 23 (8-37), -2 (-24-20) and 13 (-14-39) mmHg, respectively. Bias varied significantly over the measurement range (p < 0.001) for all three SAP techniques but not for MAP measurements. Limits of agreement for all measurements were large but less so for MAP than SAP. Variation in bias with SAP should be considered when using these measurements clinically. © 2014 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

    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.

    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.

    Total auricular reconstruction is still a challenge, and autologous cartilage transplant is the main therapy so far. Tissue engineering provides a promising method for auricular cartilage reconstruction. However, although degradable framework demonstrated excellent initial cosmetic details, it is difficult to maintain the auricular contour over time and the metabolites tended to be harmful to human body. In this study, biocompatible and safe nondegradable elastic polyurethane was used to make porous scaffold in specific details by rapid prototyping technology. Platelet-rich plasma contains fibrin and abundant autologous growth factors, which was used as cell carriers for in vitro expanded cells. When crosslinking polyurethane framework, platelet-rich plasma and cells together, we successfully made polyurethane/platelet-rich plasma/cell composites, and implanted them into dorsal subcutaneous space of nude mice. The results showed that this method resulted in more even cell distribution and higher cell density, promoted chondrocyte proliferation, induced higher level expressions of aggrecan and type II collagen gene, increased content of newly developed glycosaminoglycans, and produced high-quality cartilaginous tissue. This kind of cartilage tissue engineering approach may be a potential promising alternative for external ear reconstruction. © The Author(s) 2015.

    2013-01-01

    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.

    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.

    Myiasis caused by screwworms, Cochliomyia hominivorax (Coquerel), is devastating to warm-blooded animals and economically important to livestock producers. It is difficult to distinguish these pests, immature screwworms, from immatures of other non-pest fly species that often occur in animal wounds; it would be helpful to have tools available that do not rely on morphological characteristics. We developed two monoclonal antibodies (MAbs), highly specific for the screwworm, and used them in an enzyme-linked immunosorbent assay (MAb-ELISA), that differentiated screwworm eggs, larvae, pupae, and adults from those of the closely related secondary screwworm, C. macellaria (Fabricius) as well as Phormia regina (Meigen), Phaenicia sericata (Meigen), Calliphora vicina Robineau-Desvoidy, and Chrysomya rufifacies (Macquart). In a blind study, the microplate MAb-ELISA, which took about 4h to complete, displayed high specificity (99%), sensitivity (92%) and overall accuracy (97%) in distinguishing all life stages of the screwworm. Electrophoresis results suggested that the two monoclonal antibodies recognized identical conformational epitopes present in all screwworm life stages. The screwworm eradication program, successful in eradicating this pest from the US, Mexico, most of Central America and Libya (after an accidental introduction), could benefit in future eradication, surveillance, and exclusion efforts by developing a reliable field identification kit based on MAb-ELISA that accurately and quickly distinguished cases of screwworm myiasis.

Métodos: se implementaron los modelos celulares de Courtemanche-Ramírez-Nattel y Nygren; además se desarrolló un modelo geométrico detallado y realista de una aurícula humana, partiendo del modelo burdo de Harrild-Henriquez al que se le incorporó el direccionamiento de fibras en toda la anatomía auricular. Resultados: las constantes de difusión implementadas permitieron obtener en ambos modelos velocidades de conducción muy similares a las velocidades de conducción reales; además, en las regiones de alta conductividad el direccionamiento de fibras longitudinal permitió obtener velocidades de conducción más altas que en otras zonas de la aurícula. Conclusiones: la curva del potencial de acción muestra un APD90 (AP al 90% de la repolarización de 320 ms en NYG y 235 ms en CRN. En condiciones donde las propiedades de la membrana no han cambiado en la aurícula normal, se ha observado que en ambos modelos se generan subidas de potencial de acción rápidas que se aprecian en la forma del potencial, asociados con una baja velocidad de propagación en la dirección transversal y una subida lenta del potencial de acción, que se relaciona también con una alta velocidad de propagación en el sentido longitudinal.

    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

    The purpose of this study was to evaluate stress distribution around two craniofacial implants in an auricular prosthesis according to the removal forces. Three attachment combinations were used to evaluate the stress distribution under removal forces of 45 and 90 degrees. Three attachment designs were examined: (1) a Hader bar with three clips; (2) a Hader bar with one clip and two extracoronal resilient attachments (ERAs); and (3) a Hader bar with one clip and two Locators. The removal force was determined by means of an Instron universal testing machine with a crosshead speed of 10 mm/minute. All three designs were created in three dimensions using SolidWorks. The applied removal force and the models were then introduced to finite element software to analyze the stress distribution. The angle of removal force greatly affected the magnitude and direction of stress distribution on the implants. The magnitude of stress under the 45-degree removal force was higher than the stress at 90 degrees. The combination of the 1,000-g retention clip and 2,268-g retention Locator exhibited the highest stress on the implant flange when the removal force was applied at 45 degrees. The removal angle greatly influences the amount of force and stress on the implants. Prosthodontists are encouraged to inform patients to remove the prosthesis at 90 degrees and, if possible, use a low-retentive attachment to reduce stress.

    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.

    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.

    Auricular acupuncture (AA) is effective in the treatment of preoperative anxiety. The aim was to investigate whether AA can reduce exam anxiety as compared to placebo and no intervention. Forty-four medical students were randomized to receive AA, placebo, or no intervention in a crossover manner and subsequently completed three comparable oral anatomy exams with an interval of 1 month between the exams/interventions. AA was applied using indwelling fixed needles bilaterally at points MA-IC1, MA-TF1, MA-SC, MA-AT1 and MA-TG one day prior to each exam. Placebo needles were used as control. Levels of anxiety were measured using a visual analogue scale before and after each intervention as well as before each exam. Additional measures included the State-Trait-Anxiety Inventory, duration of sleep at night, blood pressure, heart rate and the extent of participant blinding. All included participants finished the study. Anxiety levels were reduced after AA and placebo intervention compared to baseline and the no intervention condition (p exam (p = 0.018). Participants were able to distinguish between AA and placebo intervention. Both AA and placebo interventions reduced exam anxiety in medical students. The superiority of AA over placebo may be due to insufficient blinding of participants. PMID:28033320

    Full Text Available Auricular acupuncture (AA is effective in the treatment of preoperative anxiety. The aim was to investigate whether AA can reduce exam anxiety as compared to placebo and no intervention. Forty-four medical students were randomized to receive AA, placebo, or no intervention in a crossover manner and subsequently completed three comparable oral anatomy exams with an interval of 1 month between the exams/interventions. AA was applied using indwelling fixed needles bilaterally at points MA-IC1, MA-TF1, MA-SC, MA-AT1 and MA-TG one day prior to each exam. Placebo needles were used as control. Levels of anxiety were measured using a visual analogue scale before and after each intervention as well as before each exam. Additional measures included the State-Trait-Anxiety Inventory, duration of sleep at night, blood pressure, heart rate and the extent of participant blinding. All included participants finished the study. Anxiety levels were reduced after AA and placebo intervention compared to baseline and the no intervention condition (p < 0.003. AA was better at reducing anxiety than placebo in the evening before the exam (p = 0.018. Participants were able to distinguish between AA and placebo intervention. Both AA and placebo interventions reduced exam anxiety in medical students. The superiority of AA over placebo may be due to insufficient blinding of participants.

    Transcutaneous stimulation of the auricular branch of the vagus nerve (ABVN) resulted in deactivation of temporal lobe structures, similar to invasive cervical vagus nerve (CVN) stimulation. Presumably, both methods stimulated myelinated afferent beta axons mediating anti-convulsive effects. How numbers of A beta axons in the human ABVN compare to those of the CVN is unknown. The ABVN, CVN, recurrent laryngeal nerve (RLN) and thoracic vagus nerve (TVN) were dissected from embalmed bodies. Numbers and calibers of myelinated axons were analyzed in semithin sections. Myelinated axons in the left and right ABVN averaged to 385 and 363, respectively. Numbers of A beta axons measuring ≥7 µm averaged to 64 and 78 on the left and right, respectively. Numbers of A beta axons in CVN were estimated by subtracting myelinated presumed motor axons in RLN from the total count of CVN. This resulted in 280 and 504 A beta axons on the left and right, respectively, concurring well with the thick myelinated axon count of the ipsilateral TVN (255 and 466, respectively). Thus, the ratio of A beta axons in the ABVN and CVN was ∼1:5 and 1:6 on the left and right side, respectively. These results indicate that transcutaneous ABVN stimulation might be a promising alternative to invasive CVN stimulation.

    Full Text Available Acid attacks committed as crimes of passion are unfortunately becoming far from infrequent occurrence. The injuries sustained in such attacks mainly involve the face and trunk, with the acid causing cutaneous and subcutaneous tissue burns that can result in permanent scarring, loss of the nose or external ear, and severe visual impairment. Different surgical solutions have been proposed for reconstruction of the auricle following loss of the ear through traumatic injury or cancer or in patients with congenital defects: surgical reconstruction may involve the insertion of an autogenous rib cartilage framework or the use of a porous polymer material inserted into an expanded postauricular flap. Reconstruction with rib cartilage has given good results but requires more than one surgical step and may be associated with adverse events involving both the donor site and the recipient site, while rejections of polymeric prostheses have been reported following their insertion into expanded postauricular flaps. The use of a titanium dowel-retained silicone prosthesis, in which the dowel is anchored to the temporal bone, is a surgical possibility, indicated particularly in cases of pinna resection due to tumour or auricular scarring following traumatic injury.

    Full Text Available The goal of this study was to investigate the impact and acceptability of providing continuous auricular electroacupuncture as an adjunct to conventional medications for patients with depression. Ten patients with a mean age ± SD of 43.3 ± 10.4 years were able to provide informed consent. The quantitative and qualitative outcome measures were heart rate, heart rate variability (HRV, and different clinical scores. The study documented that a special kind of auricular electro acupuncture, applied over a period of three days, can improve various aspects of quality of life significantly but also highlighted the significant increase of HRV whilst having acupuncture treatment. In conclusion, our study shows stimulation-related and quantifiable clinical and physiological alterations in parameters after continuous auricular acupoint stimulation in patients with depression. Improved access to electro acupuncture treatment would be of major benefit for these patients. Further studies are necessary in order to verify the gained results.

    A water-soluble crude polysaccharide was extracted by hot water from Auricularia auricular mycelium grown under solid-state fermentation (SSF). The crude polysaccharide was purified by DEAE Sephadex A-50 and Sephadex G-200 chromatography. Fourier transform infrared spectroscopy and nuclear magnetic resonance ((1) H NMR) spectroscopy were used to investigate the structure of the purified A. auricular polysaccharide (AAP-I) and revealed that it is α-glycosidically linked. After 14 and 28 days of AAP-I orally administered, the AAP-I significantly decreased the levels of total cholesterol, triglyceride, and low-density lipoprotein cholesterol in mice in which hyperlipidemia had been induced by a high fat diet (P < 0.05). The results revealed that AAP-I from SSF of A. auricular mycelium possesses potent hypolipidemic properties. The polysaccharide may be useful as a functional food additive and a hypolipidemic agent. © 2013 Institute of Food Technologists®

    Experiments were done to determine if transporting live screwworms Cochliomyia hominivorax Coquerel (Diptera: Calliphoridae) for developing new strains from countries where foot-and-mouth disease and classical swine fever are endemic, to the mass rearing facilities in Mexico and Panama, may introduce these exotic diseases into these countries. Are screwworms capable of harboring and spreading foot-and-mouth disease virus (FMDV) and classical swine fever virus (CSFV) when they are grown in virus-inoculated larval rearing medium? In one experiment, screwworm larvae were reared in a FMDV-inoculated artificial medium containing either 0.1 % formaldehyde or antibiotics as an antimicrobial agent. In another experiment, larvae were similarly reared in a CSFV-inoculated artificial medium containing 0.1% formaldehyde. In each experiment, samples of larvae and the rearing media were collected daily until pupation occurred. The presence of FMDV was assayed by observing cytopathic effects on cell cultures and a conventional reverse transcription-polymerase chain reaction (RT-PCR); CSFV was assayed using an avidin-biotin complex assay and a conventional RT-PCR. For media containing antibiotics, FMDV was detected in a larval sample collected on day 1 and in media samples on days 1, 2 and 3. No FMDV was detected from larval and media samples collected on all other days. For media containing formaldehyde, FMDV and CSFV were not detectable in larval or media samples collected on all sampling days. These results indicate that FMDV and CSFV cannot survive in rearing medium containing formaldehyde as an antimicrobial agent. Therefore, insects collected in endemic regions and reared using formaldehyde-containing medium for at least one generation at the collection site should be free of FMDV and CSFV and can be transported safely to a strain development/mass rearing facility.

    Maggot debridement therapy (MDT) consists on the intentional and controlled application of sterilized larvae of the order Diptera on necrotic skin lesions with the purpose of cleaning necrotic tissue and removing pathogenic bacteria. During MDT, a marked antimicrobial activity has been reported in literature specially associated with antibacterial substances from Lucilia sericata (Meigen); however, regarding Cochliomyia macellaria (Fabricius), little is known. This study aimed to evaluate in vitro inhibition of bacterial growth of Pseudomonas aeruginosa and Staphylococcus aureus in contact with excretions and secretions (ES) from C. macellaria larvae. Larval ES were extracted in sterile distilled water and divided in three groups: ES, containing 400 μL of autoclaved ES; ES+BAC, containing 400 μL of autoclaved ES+0.5-μL bacterial inoculum; and CONT-BAC, containing 400 μL of sterile distilled water +0.5 μL of bacterial inoculum. Aliquots of each experimental group were plated by spreading onto Petri dishes. Seedings were made at 0, 1, 2, 4, and 12 h after the extraction of ES. In ES+BAC groups, inhibition of S. aureus was verified between times 1 and 2 h and P. aeruginosa was inhibited between 0 and 4 h. There was no growth observed in any ES group. In the CONT-BAC groups, the number of colonies from time 4 h became countless for S. aureus and decreased for P. aeruginosa. As reported in the literature, we note here that ES have excellent bactericidal activity for both gram-positive and gram-negative bacteria, and this study shows for the first time the action of the bactericidal activity of exosecretions of C. macellaria against S. aureus and P. aeruginosa.

    To investigate the involvement of posterior auricular muscle (PAM) and the effect of botulinum toxin type A (BTX-A) injection into PAM in patients with hemifacial spasm (HFS) complicated with auricular symptoms. Sixty-three consecutive HFS patients complicated with auricular symptoms such as tinnitus or murmur, "ticking" or a "clicking" sound and discomfort on the same side, who were referred to our department between July 2009 and January 2010, were enrolled. The diagnosis of idiopathic HFS was made clinically. The patients were largely randomized into two BTX-A treatment groups according to the order of referral. The first group included 33 cases where the injection sites were routinely located at the frontal, orbicularis oculi, zygomaticus and buccinator muscles while the other was the PAM group, which included 30 cases, where 4 units of BTX-A were additionally injected into the PAM prior to injection at other sites. A test of blink reflex was performed and the lateral spread of blink reflex to the orbicularis oris (OO) and PAM, i.e. abnormal muscle response (AMR), was recorded and the peak-peak amplitude of AMR was measured. The patients were followed up clinically and electrophysiologically for at least 4 weeks (29.47 ± 2.53 days). 1) Before injection, the latencies of R1, R2, R2' were normal, there was no significant difference between uninjured and affected side; The amplitudes of R1, R2, R2' in affected side were higher. 2) After injection, there was no significant change of the R1, R2 and R2' latencies; The amplitudes of R1, R2 and R2' decreased significantly. 3) Patients reported that their auricular symptoms subsided after injection in both groups; The remission rate was 45.5% (15/33) and 76.7% (23/30) in the regular and PAM group, respectively, with a higher rate in the PAM group (χ(2) = 6.40, P = 0.011). 4) In both groups the AMR amplitude decreased significantly after injection.

    To report the efficacy of a full-thickness skin graft (FTSG) for the reconstruction of a contracted eye socket. A retrospective, non-comparative, interventional case series. This was a retrospective review of patients with a contracted eye socket who underwent socket reconstruction using a post-auricular FTSG from 2001 to 2011 at the National Taiwan University Hospital. The postoperative results including prosthetic fitting, the cosmetic result, and eyelid function were assessed. There were 11 male and 15 female patients, with a mean age of 52.3 ± 15.6 years (range 21 to 76). The duration of the socket contracture varied from three months to three years (average 7.4 ± 8.1 months). The severity of the socket contracture ranged from grade 2 to grade 4, based on Tawfik's classification. The mean follow-up time was 35.7 ± 9.6 months. After socket reconstruction, using a post-auricular FTSG, 96% of the cases (25 of 26) demonstrated a successful prosthetic fitting and a satisfactory cosmetic outcome. Both good eyelid function and a stable fornix depth were maintained during the follow-up time. One case received a second socket reconstruction three months after the first operation, using a FTSG, because of an inadequate lateral fornix. The final result was satisfactory. There were no serious complications, but a granuloma formed in one case, and there was prolonged discharge in one case. The reconstruction of a contracted eye socket using a post-auricular FTSG is an effective method with a high success rate, which causes less discomfort to donor sites and results in few complications.

    Bone marrow-derived mesenchymal stem cells (BMSCs) can be obtained by minimally invasive means and would be a favourable source for cell-based cartilage regeneration. However, controlling the differentiation of the BMSCs towards the desired chondrogenic pathway has been a challenge hampering their application. The major aim of the present study was to determine if conditioned medium collected from cultured auricular chondrocytes could promote chondrogenic differentiation of BMSCs. Auricular chondrocytes were isolated and grown in BMSC standard culture medium (SM) that was collected and used as chondrocyte-conditioned medium (CCM). The BMSCs were expanded in either CCM or SM for three passages. Cells were seeded onto fibrous collagen scaffolds and precultured for 2 weeks with or without transforming growth factor-beta 3 (TGF-β3). After preculture, constructs were implanted subcutaneously in nude mice for 6 and 12 weeks and evaluated with real-time polymerase chain reaction, histology, immunohistochemistry and biochemistry. Real-time polymerase chain reaction results showed upregulation of COL2A1 in the constructs cultured in CCM compared with those in SM. After 12 weeks in vivo, abundant neocartilage formation was observed in the implants that had been cultured in CCM, with or without TGF-β3. In contrast, very little cartilage matrix formation was observed within the SM groups, regardless of the presence of TGF-β3. Osteogenesis was only observed in the SM group with TGF-β3. In conclusion, CCM even had a stronger influence on chondrogenesis than the supplementation of the standard culture medium with TGF-β3, without signs of endochondral ossification. Efficient chondrogenic differentiation of BMSCs could provide a promising alternative cell population for auricular regeneration. Copyright © 2016 John Wiley & Sons, Ltd.

    External ear reconstruction with autologous cartilage still remains one of the most difficult problems in the fields of plastic and reconstructive surgery. As the absence of tissue vascularization limits the ability to stimulate new tissue growth, relatively few surgical approaches are currently available (alloplastic implants or sculpted autologous cartilage grafts) to repair or reconstruct the auricle (or pinna) as a result of traumatic loss or congenital absence (e.g., microtia). Alternatively, tissue engineering can offer the potential to grow autogenous cartilage suitable for implantation. While tissue-engineered auricle cartilage constructs can be created, a substantial number of cells are required to generate sufficient quantities of tissue for reconstruction. Similarly, as routine cell expansion can elicit negative effects on chondrocyte function, we have developed an approach to generate large-sized engineered auricle constructs (≥3 cm2) directly from a small population of donor cells (20,000–40,000 cells/construct). Using rabbit donor cells, the developed bioreactor-cultivated constructs adopted structural-like characteristics similar to native auricular cartilage, including the development of distinct cartilaginous and perichondrium-like regions. Both alterations in media composition and seeding density had profound effects on the formation of engineered elastic tissue constructs in terms of cellularity, extracellular matrix accumulation, and tissue structure. Higher seeding densities and media containing sodium bicarbonate produced tissue constructs that were closer to the native tissue in terms of structure and composition. Future studies will be aimed at improving the accumulation of specific tissue constituents and determining the clinical effectiveness of this approach using a reconstructive animal model.

    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.

However, long-term use of opioids is limited by development of tolerance (decreased antinociceptive efficacy) and opioid-induced hyperalgesia - paradoxical sensitization to noxious (hyperalgesia) and non-noxious (allodynia) stimuli. Novel adjunctive therapies are needed to increase the efficacy and prolong the duration of action of opioids in chronic pain treatment. Acupuncture is often used as an adjunct therapy for the treatment of symptoms induced by non-clinical use of opioids. The National Acupuncture Detoxification Association (NADA) auricular acupuncture protocol is the most common form of acupuncture treatment for substance abuse. The standardized, easy to use and virtually painless procedure make it an attractive complementary treatment option for patients suffering from opioid-induced adverse effects. Clinical trials designed to test the efficacy of the NADA protocol yielded contradictory results. The mechanism by which NADA acupuncture could serve as a successful treatment remains unknown. Therefore, establishing an animal model of NADA acupuncture can provide a tool for investigating the efficacy and cellular mechanisms of NADA treatment. Previous studies have shown that repeated morphine administration in rodents can produce locomotor sensitization and reduce analgesic potency of a challenge dose of morphine, indicating development of morphine tolerance. Here we show that NADA acupuncture treatment can both reduce morphine-induced locomotor sensitization and prevent the development of morphine tolerance in rats, thus validating a new model for NADA acupuncture studies. Our data provides support for evidence-based use of NADA acupuncture as a new adjunctive approach that can potentially improve the side-effect profile of morphine and other prescription opioids.

    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.

    Full Text Available The influence of a diet based on putrid horse meat over the post-embryonic development of Cochliomyia macellaria (Fabricius, 1775 under controlled conditions (UR 65 10% and 14 hours of photophase was compared with the results obtained using a meat broth diet to which other sources of animal and vegetable protein were added. The flies were maintained at 30ºC, from egg until mature larvae spontaneously abandoned the diet. They were then transfered to a climatized chamber at 27ºC. The larvae and pupae viability and the weight of the mature larvae were significantly inferior, when a diet based on meat broth was used, even though the larvae period was significantly increased with this diet. This type of diet did not charge the time of development of the pupae. The inoculation of the egg mass directly over the diet was recommend, instead of the technique in which the egg masses are transfered to humid filter paper, followed by the handling of the recently ecloded larvae.

    Full Text Available 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.

    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.

    Background: The National Acupuncture Detoxification Association (NADA) protocol, a simple standardized auricular treatment has the potential to provide vast public health relief on issues currently challenging our world. This includes but is not limited to addiction, such as the opioid epidemic, but also encompasses mental health, trauma, PTSD, chronic stress, and the symptoms associated with these conditions. Simple accessible tools that improve outcomes can make profound differences. We assert that the NADA protocol can have greatest impact when broadly applied by behavioral health professionals, Auricular Detoxification Specialists (ADSes). Methods: The concept of ADS is described and how current laws vary from state to state. Using available national data, a survey of practitioners in three selected states with vastly different laws regarding ADSes, and interviews of publicly funded programs which are successfully incorporating the NADA protocol, we consider possible effects of ADS-friendly conditions. Results: Data presented supports the idea that conditions conducive to ADS practice lead to greater implementation. Program interviews reflect settings in which adding ADSes can in turn lead to improved outcomes. Discussion: The primary purpose of non-acupuncturist ADSes is to expand the access of this simple but effective treatment to all who are suffering from addictions, stress, or trauma and to allow programs to incorporate acupuncture in the form of the NADA protocol at minimal cost, when and where it is needed. States that have changed laws to allow ADS practice for this standardized ear acupuncture protocol have seen increased access to this treatment, benefiting both patients and the programs.

    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 La ausencia de lóbulo auricular puede deberse a causas congénitas, oncológicas o traumáticas. Esta deformidad con frecuencia constituye una alteración estética facial que precisa de corrección quirúrgica. Se han descrito muchas técnicas para la reconstrucción del lóbulo auricular, sin embargo, algunas requieren varios tiempos quirúrgicos, dejan cicatrices en las regiones adyacentes o incluso pueden requerir injertos cutáneos complementarios. Además es complicado reconstruir la estructura tridimensional del lóbulo. En nuestra práctica, empleamos una nueva variante de colgajo bilobulado para este tipo de reconstrucción.Earlobe absence may be due to congenital, oncologic or traumatic causes. This deformity sometimes constitutes an obvious facial deformity that warrants surgical correction. There are several techniques for reconstructing the earlobe, however, most of them require more than a onestage operation, may leave scars on the cheek or the preauricular or postauricular regions and sometimes require complementary skin grafts. It is difficult to reconstruct the natural and three-dimensional structure of the earlobe. In our practice we use a new type of local flap, with transposition and rotation techniques, based in a bilobed shape flap design.

    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.

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.

The results of this investigation indicate ASK1 inhibition prolongs keratinocyte and blastemal cell activation leading to ear regeneration.

    To evaluate immune system response, skin and hepatic reactivity in Swiss mice after retro auricular local administration of two textile dyes. On 3 groups of white Swiss mice: group I (Cibacron Yellow F-4G), group II (Cibacron Orange P-2R) and control group (DMSO dimethylsulfoxide), substances were applied on left retro auricular ear, in dose of 25 microL solution 10% in DMSO (the dyes were not soluble in water), once a day, for 7 days. After euthanasia, blood samples were taken to assay differential cell count, peripheral neutrophils activity (NBT test), serum opsonic capacity, peritoneal macrophages activity (phagocytic and bactericidal capacity), and activity of spleenic T-lymphocytes with rossetting capacity, and spleen cells forming Jerne plaques. There were taken skin from local application of dyes, retro auricular and later cervical nodes from left side and hepatic samples. Retro auricular and later cervical nodes mass increases after administration of textile dyes, compared to control group. Basophiles percentages were increased after administration of two dyes (stronger after yellow dye). Peripheral neutrophils activity was increased after administration of two dyes, especially after orange dye. Administration of the two dyes decreased serum opsonic capacity and peritoneal macrophages activity, but did not influenced the activity of spleenic T-lymphocytes with rossetting capacity and spleen cells forming Jerne plaques. There were significant skin and hepatic changes in microscopy. The studied dyes influenced the activity of immune system, increased skin and hepatic reactivity.

    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.

    Abstract 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

    Full Text Available Background: Deep brain stimulation of the subthalamic nucleus (STN-DBS and the pedunculopontine nucleus (PPN significantly improve cardinal motor symptoms and postural instability and gait difficulty, respectively, in Parkinson’s disease (PD.Objective and Hypothesis: Intrinsic auricular muscle zones (IAMZs allow the potential to simultaneously stimulate the C2 spinal nerve, the trigeminal nerve, the facial nerve, and sympathetic and parasympathetic nerves in addition to providing muscle feedback and control areas including the STN, the PPN and mesencephalic locomotor regions. Our aim was to observe the clinical responses to IAMZ stimulation in PD patients.Method: Unilateral stimulation of an IAMZ, which includes muscle fibers for proprioception, the facial nerve, and C2, trigeminal and autonomic nerve fibers, at 130 Hz was performed in a placebo- and sham-controlled, double-blinded, within design, two-armed study of 24 PD patients.Results: The results of the first arm (10 patients of the present study demonstrated a substantial improvement in Unified Parkinson’s Disease Ratings Scale (UPDRS motor scores due to 10 min of IAMZ electrostimulation (p = 0.0003, power: 0.99 compared to the placebo control (p = 0.130. A moderate to large clinical difference in the improvement in UPDRS motor scores was observed in the IAMZ electrostimulation group. The results of the second arm (14 patients demonstrated significant improvements with dry needling (p = 0.011 and electrostimulation of the IAMZ (p < 0.001 but not with sham electrostimulation (p = 0.748. In addition, there was a significantly greater improvement in UPDRS motor scores in the IAMZ electrostimulation group compared to the IAMZ dry needling group (p < 0.001 and the sham electrostimulation (p < 0.001 groups. The improvement in UPDRS motor scores of the IAMZ electrostimulation group (ΔUPDRS = 5.29 reached moderate to high clinical significance, which was not the case for the dry needling

    Advancement of engineered ear in clinical practice is limited by several challenges. The complex, largely unsupported, three-dimensional auricular neocartilage structure is difficult to maintain. Neocartilage formation is challenging in an immunocompetent host due to active inflammatory and immunological responses. The large number of autologous chondrogenic cells required for engineering an adult human-sized ear presents an additional challenge because primary chondrocytes rapidly dedifferentiate during in vitro culture. The objective of this study was to engineer a stable, human ear-shaped cartilage in an immunocompetent animal model using expanded chondrocytes. The impact of basic fibroblast growth factor (bFGF) supplementation on achieving clinically relevant expansion of primary sheep chondrocytes by in vitro culture was determined. Chondrocytes expanded in standard medium were either combined with cryopreserved, primary passage 0 chondrocytes at the time of scaffold seeding or used alone as control. Disk and human ear-shaped scaffolds were made from porous collagen; ear scaffolds had an embedded, supporting titanium wire framework. Autologous chondrocyte-seeded scaffolds were implanted subcutaneously in sheep after 2 weeks of in vitro incubation. The quality of the resulting neocartilage and its stability and retention of the original ear size and shape were evaluated at 6, 12, and 20 weeks postimplantation. Neocartilage produced from chondrocytes that were expanded in the presence of bFGF was superior, and its quality improved with increased implantation time. In addition to characteristic morphological cartilage features, its glycosaminoglycan content was high and marked elastin fiber formation was present. The overall shape of engineered ears was preserved at 20 weeks postimplantation, and the dimensional changes did not exceed 10%. The wire frame within the engineered ear was able to withstand mechanical forces during wound healing and neocartilage

    Full Text Available Insulin-like Growth Factor-1 (IGF-1 is one of the significant substances affecting the growth and development of cartilage tissue in the body. The aim of this study is to evaluate the possible histopathological effects of local IGF-1 injection on the viability of rabbit auricular cartilage autografts.To this end, the single-piece and sliced cartilage tissues obtained from 20 albino rabbits’ auricula were implanted in the subcutaneous pockets created on the back skins of the experimental animals. Every two weeks IGF-1 (10 mg/ml injections were performed on the autograft implants of one group and normal saline (0.9% injections were performed on the other group. Experimental animals were sacrificed at the end of the third month. A total of 34 tissue samples obtained after dissection were evaluated and scored histopathologically according to their cartilage viability, environmental reaction, and regenerative activities.The intergroup evaluation carried out for the single-piece and sliced cartilage grafts revealed that there was statistically more cartilage viability and less foreign-body reaction in the IGF-1 group than the normal saline group (p<0.05.While there was a statistically significant difference between the groups for single-piece grafts regarding regenerative activity (p<0.05, there was no significant difference for sliced grafts. The IGF-1 group, however, showed more activity.The results we obtained point out to the fact that IGF-1 increases the tissue viability of the implanted auricular autograft and it suppresses immune modulation effect.

    The number of elderly patients with depression has steadily increased in recent years; therefore, new treatment options and therapy approaches are urgently needed to improve treatment in this patient group. The aim of this project was to evaluate the additional application of auricular acupuncture according to the NADA protocol in patients treated in a daytime ward in terms of acceptability and feasibility. A total of 20 psychogeriatric patients from a daytime clinic suffering from major depression (ICD-10: F32-F33) received auricular acupuncture in addition to the standard treatment three times per week over a treatment course of 3 weeks. Semi-structured interviews were conducted with the participants and the therapeutic team and qualitative content analyses were carried out. Depression, cognition, quality of sleep and quality of life were assessed using validated quantitative instruments. There was a 95 % utilization of the therapy. The qualitative analysis showed a high acceptance by all participants. The dominant perception by the patients was a positive expectation and conviction that acupuncture was an effective form of therapy without side effects, which could contribute to recovery. The majority of patients also felt that there was an improvement in the symptoms. The quantitative analysis revealed significant improvements in the target parameters. The acceptance of the intervention by the patients and the willingness of the interdisciplinary team underlines the feasibility of this implementation within a fixed therapeutic concept. The significant pre-post improvements indicated a potential benefit and should be verified in further efficacy studies.

    Conclusión: El implante del MP tras ablación concomitante de FA es un fenómeno multifactorial. La cirugía concomitante, grados de remodelado auricular avanzados y el propio procedimiento de ablación han sido hallados factores de riesgo independientes en el postoperatorio inmediato. Esta complicación fue reversible en más del 90% de casos de nuestra serie de forma temprana y sostenida a medio plazo.

    A common alternative treatment for substance abuse is auricular acupuncture. The aim of the study was to evaluate the short and long-term effect of auricular acupuncture on anxiety, sleep, drug use and addiction treatment utilization in adults with substance abuse. Of the patients included, 280 adults with substance abuse and psychiatric comorbidity, 80 were randomly assigned to auricular acupuncture according to the NADA protocol, 80 to auricular acupuncture according to a local protocol (LP), and 120 to relaxation (controls). The primary outcomes anxiety (Beck Anxiety Inventory; BAI) and insomnia (Insomnia Severity Index; ISI) were measured at baseline and at follow-ups 5 weeks and 3 months after the baseline assessment. Secondary outcomes were drug use and addiction service utilization. Complete datasets regarding BAI/ISI were obtained from 37/34 subjects in the NADA group, 28/28 in the LP group and 36/35 controls. Data were analyzed using Chi-square, Analysis of Variance, Kruskal Wallis, Repeated Measures Analysis of Variance, Eta square (η(2)), and Wilcoxon Signed Ranks tests. Participants in NADA, LP and control group improved significantly on the ISI and BAI. There was no significant difference in change over time between the three groups in any of the primary (effect size: BAI, η(2) = 0.03, ISI, η(2) = 0.05) or secondary outcomes. Neither of the two acupuncture treatments resulted in differences in sleep, anxiety or drug use from the control group at 5 weeks or 3 months. No evidence was found that acupuncture as delivered in this study is more effective than relaxation for problems with anxiety, sleep or substance use or in reducing the need for further addiction treatment in patients with substance use problems and comorbid psychiatric disorders. The substantial attrition at follow-up is a main limitation of the study. Clinical Trials NCT02604706 (retrospectively registered).

    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

    Inflammation is often considered to play a crucial role in epilepsy by affecting iron status and metabolism. In this study, we investigated the curative effect of auricular acupuncture and somatic acupuncture on kainic acid- (KA-) induced epilepsy in rats. 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. 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. These results indicate a novel mechanism for treating inflammation-associated epilepsy and can be translated into clinical therapy.

    Due to substantial morbidity and complications including nephropathy, a search for alternative treatment of diabetes mellitus is urgently required. The present study aimed to investigate the hypoglycemic and anti-diabetic nephropathy activities of polysaccharides separated from Auricularia auricular (AAP). Diet streptozotocin (STZ)-induced diabetic Sprague-Dawley rats were orally treated with metformin (100 mg/kg; positive control) and AAP (100 and 400 mg/kg) for four weeks, and parameters in the serum and liver associated with blood glucose, free radicals and nephropathy were determined. Similar to metformin, AAP treatment strongly reduced blood glucose levels by promoting glucose metabolism. The anti-oxidative activity of AAP, which was indicated by the modulation of superoxide dismutase, glutathione peroxidase, reactive oxygen species and methane dicarboxylic aldehyde levels in serum, was observed in diabetic rats. Furthermore, the regulatory effects of AAP on blood urea nitrogen, creatinine, uric protein and inflammatory-related factors revealed its protection against diabetic nephropathy. The present data suggests that AAP-mediated anti-diabetic and anti-nephritic effects are partially associated with their modulations on the anti-oxidative system and nuclear factor kappa B-related signaling pathway. In conclusion, AAP has potential to be a novel source of treatments for diabetes.

    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.

    The study was to explore whether auricular acupressure (AA) can relieve anxiety during the period from trans-vaginal oocyte retrieval to the embryo transfer in IVF treatment and whether AA can improve the outcomes of IVF. 305 infertile patients with tubal blockage who were referred for IVF were included. The women were randomized into a control group with 102 cases, a Sham-AA group with 102 cases and an AA group with 101 cases. The anxiety levels were rated with Spielberger's State Trait Anxiety Inventory and the Amsterdam Preoperative Anxiety and Information Scale. Data of clinical pregnancy rate (CPR), implantation rate (IR) and live birth rate (LBR) were obtained. The levels of neuropeptide Y (NPY) and transforming growth factor alpha (TGF-alpha) in the follicular fluids were detected with ELISA. After treatment, in AA group, the levels of state anxiety, preoperative anxiety and need-for-information were significantly lower, whereas CPR, IR, LBR and NPY levels in the follicular fluids were markedly higher than Sham-AA group and control group. We concluded that AA could help to reduce anxiety levels associated with IVF and improves the outcomes of IVF partly through increasing the levels of NPY in the follicular fluids.

    Glossopharyngeal, nervus intermedius, and vagus neuralgias can all present with ear pain. However, to our knowledge, there have been no reports of otalgia as the only symptom of vagus neuralgia. The seventh, ninth, and tenth cranial nerves have many interneural connections, and the exact anatomy and pathophysiology of these neuralgias are often not clear. Moreover, symptoms due to involvement of any of these nerves can be difficult to attribute solely to 1 of them. The overlapping sensory innervation of the external auditory canal can lead to misdiagnosis in patients suffering from otalgia. This report presents a case of pure otalgia due to vascular compression of the vagus nerve (VN) and considers the microanatomic differences between glossopharyngeal and nervus intermedius neuralgia via cadaveric dissections. We report 2 cases of external auditory canal pain that continued following microvascular treatment of trigeminal neuralgia. Intraoperatively and at secondary operation, the posterior inferior cerebellar artery was found to be adherent and to penetrate between the fibers of the VN. Following microvascular treatment of the VN, the pain resolved. This is the first report of vagus neuralgia presenting solely with ear pain. Surgeons should be aware that primary external auditory canal pain can be due to vagus neuralgia via its auricular branch and that such patients can be misdiagnosed with glossopharyngeal or nervus intermedius neuralgias.

    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

    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 Pclinical examnation, daily life movement and superficialmuscular pain in the neck were improved apparently after treatment as compared with those before treatment in the patients of the two groups (all Pclinical examination total scores and superficial muscular pain in the' neck were more significant in the combined therapy group

    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.

    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.

    To evaluate the effect of auricular point acupressure (APA) on axial neck pain after anterior cervical discectomy and fusion (ACDF) surgery. A prospective randomized controlled trial was performed. Twenty-nine participants were randomly divided into two groups, real or sham APA. Participants were enrolled from Shaoxing Hospital of Traditional Chinese Medicine, affiliated with Zhejiang Chinese Medical University. Eligible participants received a four-week real or sham APA treatment according to their assigned groups. The clinical outcomes were assessed by the criteria of Hosono et al., the Brief Pain Inventory Short Form (BPI), and the 36-item Short Form Health Survey (SF-36). In addition, plasma interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α were analyzed. Patients with severe or moderate axial neck pain accounted for 28.6% and 35.7% in the real APA group at the end of treatment and one-month follow-up. BPI scores were decreased in the real APA group at the end of treatment and one-month follow-up. The total mean score of SF-36 was improved in the real APA group and significantly higher than in the sham APA group. Additional, the levels of IL-1β, IL-6, and TNF-α were decreased in the real APA group. The findings supported the therapeutic effect of APA treatment on axial neck pain after ACDF surgery, and they exert the possible therapeutic effect on downregulating the levels of plasma IL-1β, IL-6, and TNF-α.

    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.

    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.

    Norberto Leonardo Murolo

    Full Text Available Resumen El presente trabajo se focaliza en los usos de la telefonía móvil como reproductor musical en el espacio público. Esta práctica es comúnmente producida por jóvenes de sectores populares, quienes escuchan cumbia o reggaeton con altavoces y sin auriculares. Esta apropiación tecnológica es generalmente combatida por sus pares, la cultura adulta, inclusive por los licenciatarios del transporte público de pasajeros que piden que no se haga. De ello que comience a haber leyes que prohíben usar reproductores musicales sin auriculares en el transporte público. En ese contexto, proponemos analizar el fenómeno desde una perspectiva cualitativa asentada en entrevistas con jóvenes y observaciones. De ellas se desprende que no se trata solamente de la molestia que causa el ruido sino que las críticas se desplazan al género musical que estos jóvenes escuchan y de allí a una fuerte presencia de discriminación de clase.

    Full Text Available Yadong Li, Jinsong Zhang, Kai Yang Department of Oral and Maxillofacial Surgery, The First Affiliated Hospital of Chongqing Medical University, Chongqing, People's Republic of China Background: Conventional radical neck dissection often causes a variety of complications. 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. It can be used as a regular surgical approach for oral carcinoma radical neck dissection.

    To compare the therapeutic effects of plum-blossom needle therapy with cupping and laser irradiation in the treatment of acute facial paralysis with ipsilateral peri-auricular pain. Sixty outpatients with acute facial paralysis and ipsilateral peri-auricular pain were divided into plum-blossom needle (treatment) group (n = 28) and laser-irradiation (control) group (n = 32). In the acute stage, patients of the treatment group were treated with plum-blossom needle tapping in combination with cupping at Yifeng (TE 17) and Wangu (GB 12), while those of the control group treated with He-Ne laser irradiation over the same two acupoints until the peri-auricular pain disappeared. The treatment was given once daily. Following disappearance of the pain, routine acupuncture treatment of Yifeng (TE 17), Wangu (GB 12), Dicang (ST 4), etc. was given continuously to patients of the two groups, once daily for 20 times. The treatment times for healing ipsilateral peri-auricular pain, and the electromyogram (EMG, compound muscle action potential) of the ipsilateral musculus orbicularis oris were recorded. Scores of the facial nerve function were given to House-Brackmann Facial Nerve Grading System. The treatment times for healing peri-auricular pain in the treatment group and laser irradiation group were 2.9 +/- 1. 0 and 6.0 +/- 2.2 respectively (t = 6.816, P = 0.000). The scores of House-Brackmann scale of the paralyzed side in the treatment group and control group were (3.3 +/- 1.5) points and (3.3 +/- 1.4) points (P > 0.05) before the treatment; (1.8 +/- 1.1) points and (2.5 +/- 1.2) points (P treatment, and (1.5 +/- 0.9) points and (2.2 +/- 1.5) points (P treatment, respectively.

    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

    Direct extracranial-intracranial (EC-IC) bypass is one of the fundamental techniques to prevent recurrent stroke in patients with adult-onset ischemic moyamoya disease. When the standard superficial temporal artery (STA) cannot be used for a graft, the posterior auricular artery (PAA) can be a potential surrogate graft. In this article, the authors reported a 34-year-old female patient suffering from ischemic moyamoya disease. To widely revascularize the anterior half of the hemisphere, direct double EC-IC bypass was considered beneficial; however, she had only a single-branched STA but had a prominent branch of the PAA. After discussion, a direct double surgical revascularization was successfully performed using a combination of the STA-middle cerebral artery (MCA) and the PAA-MCA bypass. The authors herein reported the detailed surgical technique of the PAA-MCA bypass with an informative video of the actual procedure. To clearly define the feasibility of PAA-MCA bypass, the authors also conducted a literature review, yielding 3 previous articles describing the bypass. In conclusion, the PAA becomes a potential donor for EC-IC bypass as long as its diameter is approximately 1.0 mm. Even though the PAA-MCA bypass is not primarily considered in the initial revascularization, it can be useful as a combination bypass with other grafts or as a rescue for recurrent ischemia.

    Full Text Available Although acupuncture treatment is increasingly in demand among psychiatric patients, to date no studies have investigated the effectiveness of auricular acupuncture (AA in treating anxiety disorders or major depressive disorder. Thus, this study aimed to compare the effectiveness of AA versus progressive muscle relaxation (PMR, a standardized and accepted relaxation method. We examined 162 patients with a primary diagnosis of anxiety disorder or major depressive disorder, and each patient chose between treatment with AA, executed according to the National Acupuncture Detoxification Association protocol, and treatment with PMR. Each group had treatments twice a week for 4 weeks. Before and after treatment, each participant rated four items on a visual analog scale: anxiety, tension, anger/aggression, and mood. Statistical analyses were performed with the original visual analog scale scores and the Change-Intensity Index, an appropriate indicator of the difference between two values of a variable. Our results show that treatment with AA significantly decreased tension, anxiety, and anger/aggression throughout the 4 weeks, but did not elevate mood. Between AA and PMR, no statistically significant differences were found at any time. Thus, we suggest that both AA and PMR may be useful, equally-effective additional interventions in the treatment of the above-mentioned disorders.

    Full Text Available Evidence-based research concerning the effects of high-tech acupuncture on autonomic function was performed by two research teams from China and Austria. This study describes the first transcontinental teleacupuncture measurements in animals. Heart rate (HR and heart rate variability (HRV recordings in 10 male Sprague-Dawley anesthetized rats were performed under stable conditions in Beijing, China, and the data analysis was completed in Graz, Austria. The electrocardiograms (ECGs were recorded by an HRV Medilog AR12 system during acupuncture of the ear and body (PC6 Neiguan, CV12 Zhongwan, ST36 Zusanli. The data were analyzed using specially adapted novel Austrian software. HR did not change significantly during any acupuncture stimulation in anesthetized rats (ear acupuncture, PC6, CV12, or ST36. Total HRV only changed significantly (P=0.025 during auricular acupuncture (acupoint heart. The low-frequency/high-frequency ratio parameter decreased significantly (P=0.03 during stimulation of ST36. This change was based on intensification of the related mechanism of blood pressure regulation that has been demonstrated in previous studies in humans. Modernization of acupuncture research performed as a collaboration between China and Austria has also been demonstrated.

    Full Text Available La cirugía plástica nasal tiene dos puntos centrales en su resultado: una apariencia estética agradable y una adecuada permeabilidad ventilatoria. La incidencia en la alteración o dificultad de la respiración postquirúrgica llega en la literatura publicada al respecto hasta un 10%. Una de las causas más frecuentes es la remoción excesiva de los cartílagos alares nasales, una debilidad iatrogénica que conlleva el colapso de la válvula alar nasal o externa, la deformidad del ala nasal y la obstrucción respiratoria. Están descritas numerosas técnicas quirúrgicas para el tratamiento de este colapso. Una de ellas consiste en colocar un injerto de concha auricular a modo de viga (batten graft sobre el defecto. Presentamos nuestra experiencia en 19 casos de alteraciones de la válvula alar nasal empleando esta técnica. En nuestras manos, este procedimiento logra un resultado funcional y estético óptimo debido a que mejora el soporte interno del cartílago alar y no deja alteraciones en el área donante.

    2014-01-01

    Full Text Available Auricular therapy (AT has been historically viewed as a convenient approach adjunct to pharmacological therapy for cancer patients with chemotherapy-induced nausea and vomiting (CINV. The aim of this study was to assess the evidence of the therapeutic effect of AT for CINV management in cancer patients. Relevant randomized controlled trials were retrieved from 12 electronic databases without language restrictions. Meanwhile, manual search was conducted for Chinese journals on complementary medicine published within the last five years, and the reference lists of included studies were also checked to identify any possible eligible studies. Twenty-one studies with 1713 participants were included. The effect rate of AT for managing acute CINV ranged from 44.44% to 93.33% in the intervention groups and 15% to 91.67% in the control groups. For delayed CINV, it was 62.96% to 100% and 25% to 100%, respectively. AT seems to be a promising approach in managing CINV. However, the level of evidence was low and the definite effect cannot be concluded as there were significant methodological flaws identified in the analyzed studies. The implications drawn from the 21 studies put some clues for future practice in this area including the need to conduct more rigorously designed randomized controlled trials.

    2013-01-01

    Full Text Available Resumen: La interacción entre variables es una característica inherente de los procesos multivariables, que dificulta su operación y el diseño de sus sistemas de control. Bajo el paradigma de Control por desacoplo se agrupan un conjunto de metodologías, que tradicionalmente han estado orientadas a eliminar o reducir la interacción, y que recientemente algunos investigadores han reorientado con objetivos de solucionar un problema tan complejo como es el control multivariable. Parte del material descrito en este artículo es bien conocido en el campo del control de procesos, pero la mayor parte de él son resultados de varios años de investigación de los autores en los que han primado la generalización del problema, la búsqueda de soluciones de fácil implementación y la combinación de bloques elementales de control PID. Esta conjunción de intereses provoca que no siempre se pueda conseguir un desacoplo perfecto, pero que sí se pueda conseguir una considerable reducción de la interacción en el nivel básico de la pirámide de control, en beneficio de otros sistemas de control que ocupan niveles jerárquicos superiores. El artículo resume todos los aspectos básicos del Control por desacoplo y su aplicación a dos procesos representativos: una planta experimental de cuatro tanques acoplados y un modelo 4×4 de un sistema experimental de calefacción, ventilación y aire acondicionado. Abstract: The interaction between variables is inherent in multivariable processes and this fact may complicate their operation and control system design. Under the paradigm of decoupling control, several methodologies that traditionally have been addressed to cancel or reduce the interactions are gathered. Recently, this approach has been reoriented by several researchers with the aim to solve such a complex problem as the multivariable control. Parts of the material in this work are well known in the process control field; however, most of them are

  13. Transcutaneous auricular vagus nerve stimulation regulates expression of growth differentiation factor 11 and activin-like kinase 5 in cerebral ischemia/reperfusion rats.

    Growth differentiation factor 11 (GDF11), as a rejuvenation factor in heterochronic parabiosis, can increase proliferation of primary brain capillary endothelial cells (ECs). However, the angiogenic role of GDF11 in ischemia-induced brain injury is still unclear. There are no previous reports on the spatiotemporal expression of GDF11 in cerebral ischemia/reperfusion (I/R) rats. Our recent work has strongly suggested that transcutaneous auricular vagus nerve stimulation (ta-VNS) reduces infarct size and induces angiogenesis in focal cerebral I/R rats. This study focused on expression of GDF11 and activin-like kinase 5 (ALK5) and the effects of ta-VNS in a rat cerebral I/R model. For ta-VNS, electrical stimulation of the left cavum concha (1h duration) using percutaneous needles was initiated 30min after induction of ischemia. Expression of GDF11 was analyzed by enzyme-linked immunosorbent assay, immunohistochemistry, real-time polymerase chain reaction, and western blot 24h, 3d, and 7d after reperfusion. In addition, neurobehavioral function, EC proliferation, and expression of ALK5 in ECs in the peri-infarct cortex were measured. Results showed that levels of GDF11 were significantly elevated after cerebral I/R, both in plasma and the peri-infarct cerebral cortex. Interestingly, splenic GDF11 levels decreased after ischemia. ALK5 was expressed in ECs in the peri-infarct cerebral cortex where active vessel remodeling was noted. ta-VNS improved neurobehavioral recovery, upregulated cerebral GDF11 and downregulated splenic GDF11, indicating a brain-spleen communication during stroke. ta-VNS also increased expression of ALK5 in ECs and stimulated proliferation of ECs. These results suggest that, after cerebral ischemia, GDF11 redistributes and participates in angiogenesis as an angiogenic factor that acts at least in part through ALK5. GDF11/ALK5 may represent a new potential therapy target for stroke. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Introduction and objectives: Atrial fibrillation is the most common arrhythmia in adults, with a prevalence of 0.4 percent in the general population. It is the main cause of embolic events and serious hemodynamic alterations, having important clinical, social and economic repercussions. Besides, it is the second most frequent arrhythmia in patients with an accessory pathway. The objective of the study is to characterise atrial fibrillation with anterograde conduction through an accessory pathway. Method: A descriptive, prospective and longitudinal study was carried out in 26 patients who were treated at the Cardiac Electrophysiology Services of the Ernesto Che Guevara Cardiology Hospital in Santa Clara during a year period. The variables related to the prevalence of atrial fibrillation, risk factors, circumstances of appearance, therapeutic options and predictors of sudden death, were studied. Results: It was determined a prevalence 34.2 percent with a predominance of the male gender. The most important risk factor was the existence of previous events of atrial fibrillation in 35 percent of the patients, which appeared most frequently during rest periods. There was a predominance of the left pathways (54 % and 84 percent of the patients required medication to achieve an acute reversion. Conclusions: Pre-excited atrial fibrillation presents an important prevalence in our environment. There was a predominance of the male gender and the left pathways. The mean RR interval during the pre-excitation was 213 milliseconds and there were minimal RR intervals of less than 170 milliseconds.

    Full Text Available Descrito inicialmente en 1957 por Robert Austrian, el síndrome que lleva su nombre se define como la tríada de neumonía, endocarditis y meningitis secundarias a una infección invasiva por Streptococcus pneumoniae. Desde entonces, y debido a su infrecuencia, se han reportado muy pocos casos en la literatura científica. A continuación se presenta el caso de un paciente de 61 años de edad con un cuadro inicial de meningitis bacteriana por S. pneumoniae, acompañado de neumonía bacteriana e insuficiencia mitral grave asociada a cuatro vegetaciones sobre la cara auricular de la valva posterior, con ruptura y prolapso de su festón central posterior. Se aisló S. pneumoniae, serotipo 18C, en líquido cefalorraquídeo y en dos hemocultivos. El paciente recibió antibióticos de amplio espectro y fue sometido a reemplazo valvular temprano con un resultado clínico satisfactorio. El principal factor pronóstico de esta condición lo determina el daño valvular subsecuente, sobre todo en pacientes con compromiso de la válvula aórtica, por lo que es necesario identificar tempranamente la extensión del compromiso valvular y definir oportunamente el tratamiento quirúrgico y antibiótico del paciente. En casos menos frecuentes, en los que solo hay compromiso de la válvula mitral, la evolución clínica es menos aguda y, por lo general, el tratamiento antibiótico dirigido y las medidas de soporte avanzado suelen ser suficientes para su control.

    Full Text Available El objetivo fue comparar los niveles de Pro Péptido Natriurético tipo B-N terminal (Pro-BNP-NT basales y post reversión en pacientes con fibrilación auricular solitaria (FAS de comienzo reciente y con función ventricular izquierda conservada. Se determinaron niveles del Pro BNP NT antes y después de su reversión en treinta pacientes con FAS de comienzo reciente y fracción de eyección de ventrículo izquierdo ≥ 50%. Basalmente, los niveles de Pro BNP NT fueron significativamente más elevados respecto a un grupo control sano: 529 pg/ml (157-1763 versus 31.5 pg/ml (24-76, p < 0.0001. Las concentraciones de Pro BNP NT descendieron significativamente luego de la cardioversión de 529 (157-1763 a 318 (98-870 pg/ml, p < 0.001. Los descensos se objetivaron tanto luego de la cardioversión eléctrica como de la obtenida por vía farmacológica, 345 (153-1151 pg/ml a 169 (86-407 pg/ml, p: 0.02 y de 1624 (541-4010 pg/ml a 856 (532-1160 pg/ml, p < 0.001, respectivamente. Este fenómeno se observó fundamentalmente en aquellos con una FAS con duración mayor a 8 horas: 1289 (338-2103 a 410 (169-905 pg/ml, p < 0.001. No se observó correlación entre los cambios de la frecuencia cardíaca y del Pro BNP NT pre y post cardioversión a ritmo sinusal. Se observaron descensos significativos de Pro BNP NT basalmente y post reversión (tanto farmacológica como eléctrica en pacientes con FA de reciente aparición y función ventricular conservada. Estos descensos fueron más ostensibles a partir de las 8 horas de duración de la arritmia.

    Full Text Available Oculo-auriculo-vertebral spectrum (OAVS is a rare condition characterized by the involvement of the first branchial arches. PURPOSE: To investigate the ear abnormalities of a sample of patients with OAVS. MATERIALS AND METHODS: The sample consisted of 12 patients with OAVS seen at the Clinical Genetics Unit, UFCSPA/CHSCPA. The study included only patients who underwent mastoid computed tomography and with normal karyotype. We performed a review of its clinical features, giving emphasis to the ear findings. RESULTS: Nine patients were male, the ages ranged from 1 day to 17 years. Ear abnormalities were observed in all patients and involved the external (n=12, middle (n=10 and inner ear (n=3. Microtia was the most frequent finding (n=12. The most common abnormalities of the middle ear were: opacification (n=2, displacement (n=2 and malformation of the ossicular chain. Agenesis of the internal auditory canal (n=2 was the most frequent alteration of the inner ear. CONCLUSIONS: Ear abnormalities are variable in patients with OAVS and often there is no correlation between findings in the external, middle and inner ear. The evaluation of these structures is important in the management of individuals with OAVSO espectro óculo-aurículo-vertebral (EOAV é uma condição rara caracterizada pelo envolvimento dos primeiros arcos branquiais. OBJETIVOS: Verificar as alterações auriculares de uma amostra de pacientes com EOAV. MATERIAL E MÉTODOS: A amostra foi constituída de 12 pacientes com EOAV atendidos no Serviço de Genética Clínica da UFCSPA/CHSCPA. Foram incluídos no estudo apenas pacientes submetidos à tomografia computadorizada de mastoide e com cariótipo normal. Realizou-se uma revisão dos seus achados clínicos, dando-se ênfase aos achados auriculares. RESULTADOS: Nove pacientes eram do sexo masculino, idades variaram de 1 dia a 17 anos. Anormalidades auriculares foram observadas em todos os pacientes e envolveram a orelha externa (n=12

    Full Text Available Introducción: hace algunos años se viene estudiando la relación entre disfunción diastólica y dispersión de la onda P del electrocardiograma, y en este sentido, la ecocardiografía emerge como herramienta para mejorar la estratificación de riesgo en hipertensos leves. Objetivo: determinar la dependencia de la dispersión de la onda P del electrocardiograma de variables ecocardiográficas en una población pediátrica. Métodos: se estudiaron 400 niños, de un total de 450, pertenecientes a tres escuelas primarias, y se excluyeron aquellos cuyos padres no desearon que participaran en el estudio y a quienes tuvieran patologías congénitas conocidas. Se realizó electrocardiograma de superficie de doce derivaciones y se practicaron cuatro tomas de presión arterial. Se midieron los valores de P máxima y P mínima, y se calculó la dispersión de la onda P del electrocardiograma; además se hizo, ecocardiografía para mediciones estructurales y Doppler pulsado del flujo mitral. 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

Comunicamos un caso de celulitis por CMV: una mujer de 70 años con trasplante renal efectuado 1 mes antes de la consulta, terapia inmunosupresora con ciclosporina A y metilprednisona. La paciente ingresó por fiebre, dolor e impotencia funcional en pierna derecha. Comprobamos la existencia de una placa de 8 por 4 cm eritematoedematosa. La tratamos con antibióticos sin mejoría, por lo que realizamos un estudio histopatológico de piel que mostró cambios citopáticos compatibles con infección por CMV. Los cultivos bacteriológicos y micológicos fueron negativos. La inmunohistoquímica específica para CMV y el estudio de reacción en cadena de la polimerasa (PCR de la biopsia de piel fueron positivas, al igual que la antigenemia. El tratamiento con ganciclovir produjo la mejoría del cuadro clínico. En la literatura revisada no hemos encontrado la celulitis como manifestación de enfermedad cutánea por CMV.Cutaneous lesions in CMV infection are rare, often a late manifestation of systemic infection, and usually herald a fatal course. A 70 year-old woman received a kidney transplantation one month before consulting and immunosuppressive therapy that included cyclosporine A and methylprednisone. She complained of fever, local pain in her right leg, and an erythematous and swelling plaque. She was treated with intravenous antibiotics without improvement. A skin biopsy was performed and the tissue obtained was sent for bacterial and fungal cultures as well as for histological examination. Cultures were negative. The biopsy showed CMV cytopathic changes. Immunoperoxidase staining was positive for CMV and polymerase chain reaction (PCR testing revealed CMV DNA.

    Full Text Available La amiodarona (AMD es una droga antiarrítmica potente (clase III usada en la práctica clínica para la profilaxis y el tratamiento de muchos disturbios del ritmo cardiaco, desde la fibrilación auricular paroxística hasta las taquiarritmias ventriculares que amenazan la vida. Frecuentemente causa cambios en las pruebas de función tiroidea principalmente relacionados a la inhibición de la actividad de la 5'-deiodinasa, resultando en una disminución de la generación de T3 desde T4 y el consecuente incremento en la producción de T3 reversa y una disminución de su aclaramiento. En 14 a 18% de pacientes tratados con AMD hay una disfunción tiroidea manifiesta, ya sea tirotoxicosis inducida por amiodarona (TIA o hipotiroidismo inducido por amiodarona (HIA. Tanto TIA como HIA pueden desarrollarse en glándulas aparentemente normales o en glándulas con anormalidades preexistentes clínicamente silentes. La TIA está primariamente relacionada a la síntesis de hormonas tiroideas inducida por el exceso de yodo en una glándula tiroidea anormal (TIA tipo 1 o a una tiroiditis destructiva relacionada a la amiodarona (TIA tipo 2, aunque frecuentemente ocurren formas mixtas. La tiroiditis de Hashimoto preexistente es un factor de riesgo definido para la ocurrencia de HIA. La patogenia del HIA es la falla para escapar del efecto agudo de Wolff-Chaikoff inducido por el yodo, debido a los defectos en la hormonogénesis tiroidea y, en pacientes con pruebas de autoanticuerpos tiroideos positivos, para tiroiditis de Hashimoto concomitante. La TIA es más común en zonas deficientes de yodo mientras que el HIA es usualmente visto en zonas suficientes en yodo. En contraste al HIA, la TIA es una condición difícil de diagnosticar y tratar, y usualmente se recomienda la descontinuación de la amiodarona. En esta revisión se analiza, de acuerdo a los datos actuales, las alteraciones en las pruebas de función tiroidea vistas en pacientes eutirodeos bajo

MÉTODOS: estudo retrospectivo incluindo todos os casos de IB tratados em um período de 23 anos. De acordo com a abordagem cirúrgica realizada, os pacientes foram divididos em dois grupos (1 enterolitotomia com colecistectomia no segundo momento; e (2 enterolitotomia, colecistectomia e abordagem da fístula. RESULTADOS: Doze pacientes foram incluídos, sendo 11 mulheres (91,6%, com média de idade de 72,2 anos. Todos os pacientes apresentavam doenças associadas, principalmente hipertensão arterial sistêmica (75%. Dois pacientes não apresentavam sintomas significativos de obstrução intestinal. O diagnóstico de IB foi realizado em seis pacientes (50% antes da laparotomia. O grupo 1 foi constituído de oito pacientes e o grupo 2 de quatro, e a morbidade foi, respectivamente, 33,3% e 8,3%. A mortalidade foi 16,6% (um paciente de cada grupo. CONCLUSÃO: O manejo do IB deve ser individualizado. O tratamento da obstrução mediante remoção do cálculo biliar por enterotomia proximal é a escolha inicial para o tratamento do IB. A colecistectomia e a correção da fístula bilioentérica podem ser realizadas juntamente com a remoção do cálculo, no entanto, em pacientes com comorbidades significativas, esses procedimentos devem ser realizados posteriormente.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Opioides são medicamentos frequentemente usados para o controle da dor que, contudo, podem causar hiperalgesia. A circunstância pela qual esse fenômeno pode ocorrer não está inteiramente esclarecida. O objetivo desta revisão foi descrever os mecanismos, os fatores implicados e a modulação por medicamentos. CONTEÚDO: Foram descritos os fatores implicados no desenvolvimento da hiperalgesia induzida por opioides (HIO, como duração de uso, dose e tipo de opioide. Os mecanismos incluem o sistema glutamatérgico e receptores N-metil-D-aspartato (NMDA, ativação de ciclo-oxigenase (COX espinal, aminoácidos excitatórios, dinorfina, citocinas e quimocinas; prostaglandinas e facilitação descendente. A modulação de hiperalgesia pode ser feita com antagonistas de receptores NMDA, agonistas adrenérgicos-alfa2 e inibidores de COX. CONCLUSÕES: O assunto é bastante complexo, envolvendo uma série de mecanismos fisiopatológicos que podem contribuir para a HIO e o desconforto do paciente, trazendo consequências que podem ser danosas.

Con esta reflexión deseo resaltar esa motivación de escudriñar lo desconocido, que fue también la virtud que propició el desarrollo de la personalidad de Francisco José de Caldas y Tenorio, uno de nuestros primeros y connotados sabios colombianos, y en cuyo honor se constituyó la revista de divulgación científica más importante del país, que en estos momentos cumple 76 años de existencia. Caldas tuvo curiosidad por todo lo que existía en su entorno; inicialmente en su natal Popayán, donde se maravilló por lo natural, lo que lo motivó y llevó más allá de su tierra a formar parte de la mayor empresa de exploración científica adelantada en ese entonces en territorio americano: la primera Expedición Botánica al nuevo Reino de Granada, de José Celestino Mutis.

    Federico Rodríguez Lucci

    2013-08-01

    Full Text Available La mortalidad global por accidente cerebrovascular (ACV ha disminuido en las últimas tres décadas, probablemente debido a un mejor control de los factores de riesgo vascular. La mortalidad hospitalaria por ACV ha sido tradicionalmente estimada entre 6 y 14% en la mayoría de las series comunicadas. Sin embargo, los datos de ensayos clínicos recientes sugieren que esta cifra sería sustancialmente menor. Se revisaron datos de pacientes internados con diagnóstico de ACV del Banco de Datos de Stroke de FLENI y los registros institucionales de mortalidad entre los años 2000 y 2010. Los subtipos de ACV isquémicos se clasificaron según criterios TOAST y los ACV hemorrágicos en hematomas intrapanquimatosos, hemorragias subaracnoideas aneurismáticas, malformaciones arteriovenosas y otros hematomas intraparenquimatosos. Se analizaron 1514 pacientes, 1079 (71% con ACV isquémico (grandes vasos 39%, cardioembólicos 27%, lacunares 9%, etiología indeterminada 14%, otras etiologías 11% y 435 (29% con ACV hemorrágico (intraparenquimatosos 27%, hemorragia subaracnoidea 30%, malformaciones arteriovenosas 25% y otros hematomas espontáneos 18%. Se registraron 38 muertes intrahospitalarias (17 ACV isquémicos y 21 ACV hemorrágicos, representando una mortalidad global del 2.5% (1.7% en ACV isquémicos y 4.8% en ACV hemorrágicos. No se registraron muertes asociadas al uso de fibrinolíticos endovenosos. La mortalidad intrahospitalaria en pacientes con ACV isquémico y hemorrágico en nuestro centro fue baja. El manejo en un centro dedicado a las enfermedades neurológicas y el enfoque multidisciplinario por personal médico y no médico entrenado en el cuidado de la enfermedad cerebrovascular podrían explicar, al menos en parte, estos resultados.

    DEFINICION

    * Resumen del trabajo de ingreso a la Academia.

    Según Bockus "se considera la Gastritis como un proceso inflamatorio, de variable etiología, que afecta particularmente la mucosa". La GASTRITIS POR REFLUJO suele presentarse cuando hay una disfunción del esfínter pilórico, generalmente disminución de la presión. En pacientes con estómago completo existen factores predisponentes como colecisto, pancreato o colopatías, parasitismo intestinal; o puede estar asociada a úlcera péptica, esofagitis por reflujo, ingestión de medicamentos (corticoides, analgésicos, antirreumáticos o agentes tóxicos como el alcohol; pero es, sin duda, una complicación frecuente en gastrectomizados tipo Billroth II y tras vagotomía con piloroplastia. El síndrome ha recibido también los nombres de: Gastritis biliar, Gastritis por reflujo biliar, Gastritis alcalina, Gastritis post-operatoria por reflujo alcalino, o Gastritis por reflujo alcalino postoperatorio.

    Fue observada por primera vez por Beaumont, en 1833, en su paciente Alexis St. Martin; y por Anton Wolfler, en 1881, después de una gastroentero-anastomosis. Descrita por primera vez, en 1962, por DuPlessis; y más tarde, en 1968, por Bartlett y Burrinton.

    El término de Gastritis por reflujo alcalino, fue usado por Mix, en 1922; y por Van-Heerden y colaboradores, en la Clínica Mayo, en 1969. Después de una resección gástrica, la frecuencia varía entre 5 y 350/0, según diferentes autores...

    1996-06-01

    Full Text Available Os organofosforados são um grupo de compostos químicos amplamente utilizados em agropecuária como inseticidas, ocasionando intoxicações acidentais em animais e humanos, e mesmo sendo utilizados em tentativas de suicídio. A toxicidade desses produtos decorre sobretudo de insuficiência cárdio-respiratória por compromentimento do sistema nervoso autônomo. Sabe-se que alguns destes compostos induzem em animais de experimentação e em humanos, uma miopatia caracterizada por degeneração de células musculares, comprometendo sobretudo a musculatura respiratória. Baseado no fato de que este comprometimento contribui para a piora da função respiratória, propõe-se um protocolo de avaliação rotineira de miotoxicidade por compostos organofosforados, através de uma bateria mínima e suficiente de colorações e reações histoquímicas para quantificação da necrose muscular. Utilizaram-se como modelo experimental, grupos de ratos albinos (Wistar intoxicados com o organofosforado paraoxon, com e sem antídotos (atropina ou pralidoxima. Verificou-se nos grupos tratados com paraoxon e paraoxon mais atropina, necrose de fibras musculares no diafragma, que atingia em determinadas áreas até 15% das fibras. No grupo tratado com paraoxon mais pralidoxima, a necrose foi mínima, evidenciando o papel mioprotetor deste último antídoto.Organophosphates comprise a group of chemical compounds extensively used in farming as insecticides, which cause accidental poisoning in animals and men and are also used in suicide attempts. The toxicity of these compounds is due especially to the cardiac and respiratory impairment in consequence of autonomic nervous system disorders. However, it is known that some of these products induce a myopathy in experimental animals and humans. This myopathy is characterized by muscle cell degeneration, involving above all the respiratory muscles. Based on the fact that this involvement certainly enhances the

    Full Text Available Una niña indigena de 4 años de edad, procedente de Carurú, Vaupés, un municipio semiselvático de 2.000 habitantes, presentó hematoquecia repetida con sincope y muerte 4 días después, a pesar de recibir transfusiones sanguíneas. El estudio postmortem descubrió dos masas de 3-4 cm de diámetro en el ileon distal que, al microscopio, correspondieron a inflamación severa de toda la pared intestinal, rica en eosinofilos y en granulomas con células gigantes que circunscribian y fagocitaban huevos y larvas de Angiostrongylus costaricensis, helminto situado también dentro de las arterias de la submucosa, vasos que presentaban engrosamiento de la intima y focos con inflamación granulomatosa con eosinófilos. La niña no presentó leucocitosis ni eosinofilia. Este es el segundo caso de angiostrongilosis de esta región. El primero fue el de una mujer indigena de 34 años también con hematoquecia anemizante. La angiostrongilosis abdominal se diagnosticó por primera vez en Colombia en 1979, en un niño de 5 años, de Dagua, Valle. La niña aquí presentada es el sexto paciente con esta entidad en Colombia. La hematoquecia como manifestación predominante de la angiostrongilosis es extraordinaria para una enfermedad parasitaria; se ha registrado solamente en tres ocasiones anteriores. La abundancia de cristales de Charcot-Leyden, que se tiñen muy bien con la coloración de Ziehl-Neelsen o de Fite-Faraco, en los infiltrados de la pared intestinal. sugiere que su búsqueda en las heces puede ser una ayuda en el diagnóstico de casos sospechosos. pues, los huevos y las larvas no se eliminan en las heces y el diagnóstico definitivo de la angiostrongilosis es histopatológico. Revisamos las caracteristicas clinicas, parasitológicas e histopatológicas de esta parasitosis que será más prevalente en Colombia a medida que los médicos. especialmente los patólogos, la conozcan mejor.

    Full Text Available El tatuaje por amalgama se origina por el depósito en el tejido conectivo subepitelial de fragmentos de amalgama resultado de procedimientos iatrogénicos por parte del operador. La profundidad a la que se encuentren albergados los residuos de este material influye en la presentación clínica de las lesiones. Radiográficamente se pueden identificar los fragmentos mientras tengan diámetros razonables; histológicamente se pueden observar las partículas de amalgama como gránulos oscuros, sólidos e irregulares dispuesto entre los haces de colágeno y vasos sanguíneos. Este artículo refiere el caso clínico de un paciente que presentó pigmentación por amalgama en mucosa vestibular, originada por una porción de amalgama usada como material obturador en una apicectomía del 11 realizada con anterioridad. Teniendo en cuenta las consideraciones clínicas y radiográficas se optó por realizar una segunda apicectomía con obturación retrógrada con MTA del 11. Durante el procedimiento quirúrgico se cureteó y adelgazó la cara interna del colgajo mucoperióstico para tratar de disminuir el grado de pigmentación.

    Full Text Available Este trabalho foi realizado para avaliar os achados da angiografia por tomografia computadorizada, comparativamente à angiografia por subtração digital, em relação aos aneurismas intracranianos, e a possibilidade da maior utilização da angiografia por tomografia computadorizada no Brasil. Foram analisados oito pacientes que apresentavam um total de sete aneurismas não tratados e um aneurisma tratado. Houve subseqüente correlação com outros trabalhos publicados na literatura médica. Os exames foram realizados em uma clínica e em dois hospitais privados, na cidade do Rio de Janeiro, RJ. Foi demonstrada boa correlação entre os métodos estudados, em relação ao diagnóstico dos aneurismas, no acompanhamento e avaliação pré-terapêutica dessas lesões. A angiografia por tomografia computadorizada foi um exame menos invasivo, de menor custo e maior acessibilidade. Concluiu-se que a angiografia por tomografia computadorizada é um exame que deve ser utilizado com maior freqüência para avaliação nesta enfermidade.

De um total de 545 ovinos, oito animais adoeceram (1,46% e quatro destes morreram (50%. A avaliação das instalações e do manejo indicaram como fatores predisponentes a ingestão excessiva de mistura mineral e a restrição hídrica. Os principais sinais clínicos foram decúbito, diminuição ou ausência da sensibilidade cutânea, ausência dos reflexos de ameaça, palpebral e auricular, midríase, nistagmo, opistótono, espasticidade de membros, sonolência e estupor. Havia ainda, timpanismo, diarreia, taquipneia, taquicardia, desidratação e poliúria. A evolução do quadro clínico nos animais que morreram variou de duas horas e meia a 48 horas. As médias das concentrações séricas de sódio e de potássio de 31 ovinos do mesmo lote afetado pela intoxicação, em amostras colhidas durante o surto, revelaram hipernatremia (190mEq/l e hipercalemia (8,2mEq/l. À necropsia, observou-se em um animal, achatamento das circunvoluções cerebrais. Microscopicamente, neste animal, evidenciou-se vacuolização moderada do neurópilo, particularmente nas lâminas intermediárias do córtex cerebral, com aumento dos espaços perineural e perivascular. Nessas áreas foram observados ainda, acentuada tumefação e edema dos astrócitos e necrose neuronal aguda. A dosagem de sódio no encéfalo de um ovino, revelou-se elevada com valor de 3.513ppm. O diagnóstico foi realizado com base na epidemiologia, nos sinais clínicos, nas lesões macro e microscópicas e nas dosagens de sódio no soro e no encéfalo dos ovinos.

In our experiments, AT consisted of placing Vaccaria seeds over the “fingers point” of one ear. Two groups of healthy volunteers were enrolled for the study. Each subject was asked to perform an autoalgometric test developed by our group on three occasions: before, 1 hour after, AT and 24 hours after AT. Participants of the first group received a 2-minute long session of AT, while participants of the second group received a 2-minute long session of sham treatment, consisting of a puncture/massage above the skin of the neck. The autoalgometric test consisted of applying an increasing pressure with the finger-tips and finger-backs of four fingers by the subjects themselves (i.e., eight sites were evaluated against a round-shaped needle for two times: until a minimum pain sensation (first time, minimal test or a maximally tolerable pain sensation (second time, maximal test. Our results showed a significant higher pain threshold in the maximal test at 24 hours after AT compared to sham treatment. This result indicates for the first time that AT can increase pain tolerability, rather than affecting the minimal pain threshold.

Schmid ni lo pensó: de inmediato aceptó el reto y un año después entregó la obra (y toda su vida diría, medio en serio, medio en broma, que aquella casa le había quedado aun mejor y más bella que las hechas por el propio Le Corbusier, por cierto compatriota suyo. Allí vivieron durante décadas los Trujillo: el maestro, Sara (su esposa y sus hijos. La casa aún se mantiene en pie: ocupa una amplia esquina, en la calle 58 con carrera tercera, en el muy bogotano barrio de Chapinero. Es más, fue restaurada y bajo el nombre de Casa Trujillo es hoy un conjunto de apartamentos.

  12. Por un humor ético

    2016-04-01

    Full Text Available Ética del humor es una obra original, abundantemente documentada, de contenido científico y filosófico, que aborda un problema de gran importancia en los actuales estudios de éticas aplicadas. La ética del humor es una nueva ética aplicada que pretende comprender el fenómeno del humor a la luz de sus implicaciones éticas. Como señala el autor, Juan Carlos Siurana, reputado experto en el ámbito de la filosofía práctica, el interés por el humor es un interés por la ética. En la obra no presenta una nueva teoría filosófica del humor –las cuales se han venido sucediendo, al menos, desde los Diálogos de Platón–, sino una nueva teoría ética, que toma al humor como objeto principal de análisis. Por tanto, la finalidad es realizar una aportación dentro del ámbito de la ética. Para ello se nutre de distintos estudios psicológicos, biológicos, fisiológicos y neurológicos sobre el humor, así como de clásicas obras de filosofía que han abordado esta cuestión.

    Full Text Available OBJETIVO: Describir la epidemiología de la intoxicación aguda por plaguicidas (IAP en el Hospital General O'Horán de Mérida, Yucatán, México. MATERIAL Y MÉTODOS: Se revisaron los expedientes de 33 pacientes superscript three 13 años, tratados en una unidad de cuidados intensivos (UCI, entre 1994 y 1998. Se recopilaron variables demográficas y clínicas relevantes, y se aplicó estadística descriptiva. RESULTADOS: En la población estudiada predominó el sexo masculino (82% del medio rural (70%, y la edad media fue de 34 ± 15.8 años. El intento de suicidio fue causa frecuente de IAP (79%, y en 33% de los casos la intoxicación se produjo por la utilización de organofosforados. La mortalidad fue de 12%. CONCLUSIONES: La IAP fue baja entre los sujetos del medio rural, por lo que los resultados de este estudio parecen no reflejar la realidad del problema. Es importante añadir que los plaguicidas son utilizados con relativa frecuencia para el intento de suicidio.

  14. ESTUDOS SOBRE A PSICOTERAPIA MEDIADA POR COMPUTADOR

    2015-12-01

    Full Text Available Levando em consideração que o avanço tecnológico vem influindo em diversos setores, inclusive no campo da Psicologia, torna-se importante entender como tal inserção tem sido percebida pela sociedade. A mais atual regulamentação desenvolvida pelo Conselho Federal de Psicologia foi a Resolução 011 de junho de 2012. O Conselho determinou que são reconhecidos diferentes serviços psicológicos realizados por meios tecnológicos de comunicação, como as orientações psicológicas em até vinte encontros virtuais. O atendimento psicoterapêutico mediado por computador, por sua vez, apenas é permitido em caráter experimental. Um adendo que pode vir a somar a reflexão de tal forma de trabalho, é que alguns atendimentos realizados por Freud e Jung se deram através de textos. O presente trabalho objetiva refletir acerca da opinião de moradores da cidade de Campos dos Goytacazes, norte fluminense do Rio de Janeiro, sobre a questão dos serviços psicológicos mediados por computador. O trabalho iniciou-se com a elaboração de um questionário que foi aplicado a quarenta sujeitos, de ambos os gêneros, com formação superior completa e moradores de Campos, passando a uma análise quantitativa dos dados. Um levantamento bibliográfico embasou a pesquisa. Quase que a totalidade da amostra reconhece a relevância da Psicologia para a vida das pessoas. Seja pela pouca divulgação ou até pelo receio frente os rápidos avanços tecnológicos, concluiu-se haver uma certa resistência em relação a referida prática online. Em relação a análise acerca de ser possível ou não haver uma psicoterapia online, as respostas da amostra não foram homogêneas. Na questão que dizia respeito a percepção da confidencialidade de psicoterapias presenciais e de psicoterapias virtuais, sessenta por cento, ou seja, mais da metade, da amostra ainda percebe a psicoterapia presencial como a mais sigilosa. Isto permite a inferência sobre a predomin

    The type IX secretion system (T9SS) has been recently discovered and is specific to Bacteroidetes species. Porphyromonas gingivalis, a keystone pathogen for periodontitis, utilizes the T9SS to transport many proteins including the gingipain virulence factors across the outer membrane and attach them to the cell surface via a sortase-like mechanism. At least 11 proteins have been identified as components of the T9SS including PorK, PorL, PorM, PorN and PorP, however the precise roles of most of these proteins have not been elucidated and the structural organization of these components is unknown. In this study, we purified PorK and PorN complexes from P. gingivalis and using electron microscopy we have shown that PorN and the PorK lipoprotein interact to form a 50 nm diameter ring-shaped structure containing approximately 32–36 subunits of each protein. The formation of these rings was dependent on both PorK and PorN, but was independent of PorL, PorM and PorP. PorL and PorM were found to form a separate stable complex. PorK and PorN were protected from proteinase K cleavage when present in undisrupted cells, but were rapidly degraded when the cells were lysed, which together with bioinformatic analyses suggests that these proteins are exposed in the periplasm and anchored to the outer membrane via the PorK lipid. Chemical cross-linking and mass spectrometry analyses confirmed the interaction between PorK and PorN and further revealed that they interact with the PG0189 outer membrane protein. Furthermore, we established that PorN was required for the stable expression of PorK, PorL and PorM. Collectively, these results suggest that the ring-shaped PorK/N complex may form part of the secretion channel of the T9SS. This is the first report showing the structural organization of any T9SS component. PMID:27509186

    Full Text Available Uma variante da cefaleia crônica diária, a cefaleia por uso excessivo de medicamentos é uma manifestação clínica de frequência ≥ 15 dias por mês, durante 3 meses. Possui um diagnóstico deficiente e um tratamento dividido em etapas, sendo a desintoxicação, a etapa de fundamental importância. Este artigo apresenta uma revisão sobre o tema, contribuindo para o esclarecimento das principais manifestações clínicas, principais teorias envolvendo sua fisiopatologia e a terapêutica farmacológica empregada. A metodologia utilizada foi uma revisão de publicações europeias e americanas, no período de 2001 a 2013, nos idiomas português, inglês e espanhol. Todos os medicamentos utilizados no tratamento sintomático das cefaleias são capazes de cronificar uma cefaleia preexistente, desde que sejam utilizados excessivamente, de forma regular e continuada. A suspensão de tais agentes terapêuticos resultará em melhoria na maioria dos pacientes, porém pode ser necessária a introdução de uma terapia de suporte de transição e/ou terapia profilática. Os tratamentos nao farmacológicos, quando associados ao farmacológico, ampliam a possibilidade de resultados satisfatórios, evitando recaídas.

    Full Text Available São apresentados 31 casos de bacteremia por gram-negativos, assunto que vem merecendo muita atenção dos pesquisadores nos últimos anos. Os organismos etiológicos mais importantes que apareceram em igualdade de freqüência foram Escherichia coli e Klebsiella-Aerobacter, sendo responsáveis por 58% do total das infecções, seguidos por Pseudomonas. A porta de entrada mais freqüente foi o trato urinário em 61,3% dos casos. A infecção foi mais comum no sexo masculino e a faixa etária de 50 a 60 anos predominou. O uso prévio de antibióticos foi um fator predisponente muito importante, seguido pelo uso de esteróides e citostáticos. As principais doenças predisponentes foram diabetes mellitus e neoplasias malignas. Os principais fatores precipitantes foram a manipulação do aparelho urinário, com infecção prévia ou desencadeada, cirurgia do aparelho digestivo, uronatia obstrutiva e obstrução biliar. As principais manifestações clínicas foram a presença de febre, calafrios e hipotensão arterial. A complicação mais freqüente foi o choque bacteriano que incidiu em 58% dos casos, aproximadamente três vêzes aquela relatada na literatura. As outras foram a insuficiência renal aguda, superinfecção e infecção pulmonar metastática. Considerações terapêuticas gerais e esquemas de antibióticos são propostos para estes casos. A mortalidade da bacteremia simples foi de 30,7% e quando associada ao choque elevou-se para 72,2% . As infecções por Pseudomonas foram 100% fatais.

Ao exame clínico, 9,5% (4/42 dos bovinos apresentavam sintomatologia nervosa, como leve a moderada rotação da cabeça, apatia, flacidez dos lábios e ptose palpebral unilateral, alopecia das regiões da cabeça e cupim, causados pelo desconforto e prurido da região auricular, alteração na mastigação e acúmulo de alimento na cavidade oral. Adicionalmente, 71,4% (30/42 dos abovinos mostraram a presença do parasita no cerúmen dos condutos auditivos. À análise microscópica do material do saco conjuntival foi observado presença do parasita em 90% (9/10 dos bovinos avaliados. Os 30 bovinos positivos para Rhabditis spp. foram distribuídos aleatoriamente em três grupos de 10 animais: (G1 Bovinos controle, (G2 Bovinos tratados com ivermectina 1% pour on e (G3 Bovinos submetidos a lavado dos condutos auditivos externos (CAE. Cada tratamento foi repetido três vezes com intervalo de sete dias. No G1 os 10 bovinos mantiveram-se infectados durante todo o estudo. No G2 20% dos bovinos foram negativos após os dois primeiros tratamentos, porém, mostraram-se positivos na terceira avaliação. No G3 todos os bovinos mantiveram-se positivos, sendo observada apenas diminuição da carga parasitária. A identificação por análise molecular por meio de fragmentos amplificados da expansão D2/D3 do 28S rDNA confirmou a presença apenas da espécie Rhabditis blumi nos animais. Baseado nas observações clínicas, morfológicas e moleculares pode-se relatar o primeiro caso de R. blumi em bovinos da raça Gir no Estado do Pará, através da compra de animais oriundos de áreas onde a otite parasitária tem sido diagnosticada, principalmente de Minas Gerais, para

    Full Text Available

    O presente artigo pretende fazer uma reflexão, a partir de Gramsci e de Sartre, sobre como as práticas do intelectual e do jornalista, formados em um mesmo locus social, como “técnicos do saber prático”, distanciam-se em virtude dos diferentes compromissos assumidos socialmente. O artigo pretende expor, portanto, alguns dos motivos, a partir da prática do jornalista, que o levam a se afastar da noção de intelectual, embora, muitas vezes, ele reivindique esse status. Argumenta-se sobre como a incorporação da retórica da neutralidade pelos jornalistas, derivada do racionalismo de que a classe burguesa se tornou representante, constituiu um dos braços para a construção dos pressupostos jornalísticos da imparcialidade e da objetividade. Por fim, argumenta-se, a partir das revistas semanais de informação Época, Veja e Istoé, sobretudo nas reportagens de comportamento, sobre como essa retórica instaura uma falsa arena de discussão pluralista nesses semanários sustentada por uma visão naturalizadora das relações humanas, valores, práticas culturais e do próprio ser humano.

    Full Text Available A nodulose por metotrexato (MTX é um dos efeitos colaterais pouco conhecidos do uso desse medicamento em doses baixas. Embora classicamente descrita em casos de artrite reumatóide, tem aparecido, também, em outras doenças reumáticas. Descreve-se aqui um caso de nodulose por MTX em uma paciente com artrite reumatóide soropositiva, que utilizava esse medicamento há um ano, com bom controle do processo articular. Segue-se uma breve revisão sobre o assunto.Methotrexate-induced nodulosis is a rare side effect of this drug when it is used in low doses. Although classically described in rheumatoid arthritis patients, it may also appear in other rheumatic disorders. We describe a seropositive rheumatoid arthritis patient who developed methotrexate-induced nodulosis after using this drug for a year, with good control of articular symptoms. This case presentation is followed by a brief revision on the subject.

  19. Luchas por el control territorial en Colombia

    Full Text Available La tesis central del artículo es que la concurrencia entre los impactos de la globalización, el proceso de descentralización y la crisis política debilitan gravemente el Estado-Nación, y particularmente tienden a romperse las bases mismas del centralismo polÌtico, administrativo y económico. Por otra parte, se exacerban las luchas locales por la apropiación de las riquezas materiales y el control de las instituciones. De esta manera, se acrecienta el poder de negociación política de las fuerzas locales frente al gobierno central, tanto respecto de las funciones descentralizadas como de aquellas que mantiene el Estado de manera centralizada. Neoliberales, reformadores políticos, clases políticas territoriales, nuevos movimientos sociales, narcotraficantes, guerrilleros y paramilitares se disputan abiertamente el poder local. Todos tienen una estrategia, o al menos un conjunto de intereses y prácticas respecto del proceso de descentralización, el cual en última instancia no puede ser entendido sino como el resultado de la complejidad de fuerzas que intervienen en él.
