    Full Text Available Two new procedures for the elaboration of alkali-treated green table olives, without fermentation, preserved by sterilization or pasteurization were studied. In each case, the aim was to obtain a product with good quality and guaranteed safety. In the sterilized product, it was demonstrated that by including a pitting step during elaboration, a product was obtained with both flavour and texture similar to those of «green ripe olives», but without the need to apply an excessive number of washes. Alkalizing agents added to the packing solution negatively affected the organoleptic olive properties. In case of the pasteurized product, a pitting step during elaboration was also demonstrated to be effective in improving olive flavour. Fruit texture was not significantly affected by this step. Both herbal extracts and monosodium glutamate added to the packing solution successfully masked the «cooked» flavour of olives associated with pasteurisation.En el presente trabajo se han estudiado dos nuevos procedimientos para la elaboración de aceitunas verdes tratadas con álcali no fermentadas, conservadas por esterilización o pasterización, con el objetivo de obtener, en cada caso, un producto de calidad adecuada y de total garantía en cuanto a seguridad. En el producto esterilizado, se demostró que la inclusión de una etapa de deshuesado durante la elaboración conseguía un sabor y textura similares a las aceitunas denominadas «green ripe olives», pero sin necesidad de aplicar un excesivo número de lavados. Sin embargo, la adición de agentes alcalinizantes afectó negativamente a las características organolépticas de este producto. En el caso del producto pasterizado, el deshuesado del fruto consiguió también una notable mejora del sabor sin afectar significativamente a la textura. La adición de extractos de hierbas aromáticas o de glutamato monosódico a la salmuera de envasado enmascaró el característico sabor a

    Full Text Available A mordida aberta é uma anomalia com características distintas que, além da complexidade dos múltiplos fatores etiológicos, traz consequências estéticas e funcionais. Muitas alternativas têm sido utilizadas em seu tratamento, entre elas a grade palatina, forças ortopédicas, ajuste oclusal, camuflagem com ou sem exodontias, mini-implantes ou miniplacas e cirurgia ortognática. O diagnóstico preciso e a determinação da etiologia permitem estabelecer os objetivos e o plano de tratamento ideal para essa má oclusão. O presente relato descreve o tratamento de uma má oclusão Classe I de Angle, com padrão esquelético de Classe II e mordida aberta anterior, realizado em duas fases e que foi apresentado à diretoria do Board Brasileiro de Ortodontia e Ortopedia Facial (BBO, representando a categoria 2, como parte dos requisitos para a obtenção do título de Diplomado pelo BBO.Open bite is an anomaly with distinct characteristics which, in addition to involving complex, multiple etiologic factors, entails aesthetic and functional consequences. Many alternative approaches have been employed to treat open bite, including palatal crib, orthopedic forces, occlusal adjustment, camouflage with or without extractions, mini-implants or mini-plates, and orthognathic surgery. By determining accurate diagnosis and etiology professionals can set the goals and ideal treatment plan for this malocclusion. This report, describing the two stages treatment of a Angle Class I malocclusion with Class II skeletal pattern and anterior open bite, was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO, representative of category 2, as partial fulfillment of the requirements for obtaining the title of BBO Diplomate.

    2004-02-01

    Full Text Available Dieulafoy's disease is an uncommon but potentially significant cause of gastrointestinal bleeding caused by a large-caliber arterial vessel in the submucosa, which causes erosion and debilitation of the surrounding mucosa and may lead to massive gastrointestinal bleeding. Since endoscopy may prove insufficient, echoendoscopy may help in the diagnosis of this condition. Echoendoscopy may also help improve endoscopic management using mechanical techniques (hemoclips or band ligation or a combination of thermal techniques and injection sclerotherapy, since this allows an accurate localization of the submucosal vessel. We present a case illustrating this approach by endoscopic ultrasonography, and describe the morphological substrate of this condition.La enfermedad de Dieulafoy constituye una causa rara pero potencialmente muy grave de hemorragia digestiva. Se debe a la presencia de un vaso arterial de gran calibre en la submucosa, en contacto con una mucosa a la que debilita y erosiona, lo que puede conducir a un sangrado digestivo de gran magnitud. El diagnóstico endoscópico no siempre es fácil, siendo la ecoendoscopia una técnica que puede venir a solucionar estas dificultades. Además, dado que permite localizar con gran exactitud este vaso submucoso, puede contribuir a aumentar la precisión del tratamiento endoscópico mediante métodos mecánicos (hemoclips o bandas elásticas o la combinación de métodos térmicos y la inyección de sustancias esclerosantes. Presentamos a continuación un caso que ilustra perfectamente esta aplicación de la ultrasonografía endoscópica, definiendo perfectamente el sustrato morfológico de esta entidad.

    Full Text Available La encefalopatía hepática es un estado reversible de alteración en la función cognitiva, que puede ocurrir en pacientes con enfermedad hepática aguda o crónica o shunts porto-sistémicos, en el que puede aparecer cualquiera de los signos neurológicos o psiquiátricos conocidos. Las sustancias nitrogenadas procedentes de la digestión intestinal alcanzan el cerebro sin la depuración que supone su paso por el hígado, debido a las derivaciones porto-sistémicas, y dan lugar a los signos característicos de la encefalopatía hepática. A continuación presentamos dos casos clínicos de pacientes con shunt porto-sistémicos, diagnosticados de encefalopatía hepática crónica recurrente refractaria al tratamiento médico convencional, tratados satisfactoriamente con embolización de dicho shunt mediante técnicas de radiología intervencionista.Hepatic encephalopathy is a reversible state of altered cognition that may occur in patients with acute or chronic liver disease or porto-systemic shunt, and in which known neurological or psychiatric signs may develop. Nitrogenated substances from intestinal digestion reach the brain without being cleared by their passage through the liver due to the presence of porto-systemic shunt. We report two cases of patients with porto-systemic shunt diagnosed with recurrent chronic hepatic encephalopathy refractory to conventional medical treatment. They were satisfactorily treated with shunt embolization using interventionist radiology techniques.

Se evaluaron seis parámetros: índice glenohumeral horizontal, índice glenohumeral vertical, inclinación glenoidea, ángulo de anteversión de la escápula, ángulo glenoideo y retroversión humeral. Encontramos diferencias estadísticamente significativas entre los grupos LRH y HEC en relación al índice glenohumeral horizontal. Ambos grupos (LRH y HEC mostraban diferencias significativas en comparación con el grupo de hombros normales (HN en relación al índice glenohumeral horizontal, inclinación glenoidea y ángulo de anteversión de la escápula. La desproporción cefalo-glenoidea y la inclinación anterior glenoidea son los factores anatómicos desestabilizantes. Nuestros resultados confirman que, aunque la etiología de la inestabilidad anterior de hombro es multifactorial, existe una predisposición congénita anatómica que la favorece y, en menor grado, también en el hombro estable contralateral, confirmando la existencia de una sutil displasia congénita. Además se revelan como parámetros relevantes en el estudio de la inestabilidad anterior: el índice glenohumeral horizontal, inclinación glenoidea y ángulo de anteversión de la escápula, siendo discutido el papel de la retroversión humeral.We have carried out a scapulometric study, using CT-scan, of 98 shoulders: 36 with recurrent anterior shoulder dislocation (RAD, 37 stable contralateral shoulders (CSS and 25 normal shoulders (NS. Six parameters were evaluated: Horizontal and Vertical glenohumeral index, glenoid tilt, anteversion angle of the scapula, glenoid angle and humeral retroversion.

    Full Text Available El objetivo de este trabajo fue el de verificar la eficiencia del tratamiento químico en la prevención del taponamiento de los sistemas de goteo, cuando se usa aguas residuales sanitarias tratadas. Para la realización del ensayo experimental fue construida una plataforma de ensayos con la finalidad de abastecer cuatro unidades de irrigación por goteo con aguas residuales sanitarias, tratada y filtradas mediante un filtro de disco de 120 mesh. Fueron ensayados tres modelos de goteros (M1, M2 y M3 durante un período de 560 horas. En el tratamiento químico fueron ensayadas las concentraciones de cloro residual libre de 0; 0,4; 1,0 y 1,9 mg L-1. A partir de los resultados obtenidos se tienen las siguientes conclusiones: el agua residual sanitaria, tratada por aplicación vía sistema de irrigación por goteo propicio la formación de un biofilme en los goteros, resultante de la interacción entre colonias de bacterias y algas. La aplicación de cloro en el agua residual sanitaria tratada, minimizó el desarrollo del biofilme en el interior de los goteros y de las líneas laterales de irrigación; además, se encontró que los goteros con mayor diámetro en el laberinto y con mas de un filtro secundario (M2 y M3, son mas susceptibles al taponamiento cuando trabajan con aguas residuales tratadas. La concentración de cloro residual libre de 0,4 mg L-1 fue mas sustentable en la prevención de taponamiento por biofilme en sistemas de riego por goteo que operan con agua residual domestica tratada.

    Full Text Available RESUMO Objetivo: Estudar, através do exame histopatológico, a epidemiologia de ceratites fúngicas tratadas com ceratoplastia penetrante terapêutica, enfatizando a presença de cirurgia ocular prévia. Métodos: Inicialmente, o estudo foi observacional e transversal de botões corneanos provenientes de ceratoplastia penetrante no período de 2006-2015 enviados para exame histopatológico ao banco de olhos do Hospital Geral de Fortaleza. Os tecidos foram corados com Hematoxilina-eosina, PAS ou Grocott, e examinados com microscópio óptico. Foram selecionados casos com diagnóstico histopatológico de ceratite fúngica. Após a selecão, realizamos revisão de prontuários buscando idade e sexo do paciente, data(s do(s transplante(s por ceratite fúngica, diagnóstico clínico précirúrgico, presença/tipo de cirurgias anteriores e/ou posteriores. Incluímos 62 botões corneanos de 55 pacientes. Resultados: A maioria dos pacientes era do sexo masculino. Apenas 7 (11,29% casos tiveram recidiva da infecção tratada cirurgicamente. 10 (16,13% casos possuíam cirurgia ocular prévia a ceratite fúngica tratada por transplante. Nenhum caso teve ceratite fúngica como diagnóstico clínico pré-cirúrgico. A principal forma de fungo no exame histopatológico foi forma leveduriforme isolada, seguida pela leveduriforme associada à filamentosa. O aspecto predominante da membrana de Descemet foi livre de fungos. Conclusão: Demonstramos o potencial curativo das ceratites fúngicas quando tratadas com ceratoplastia penetrante terapêutica e uma possível associação do fator cirurgia ocular prévia ao desenvolvimento dessas infecções. Características do exame histopatológico foram abordadas diferente de outros estudos que, em sua maioria, citam apenas o exame microbiológico. A dificuldade no diagnóstico clínico précirúrgico foi ressaltada, o que pode ter contribuído com a evolução dos casos estudados para tratamento cirúrgico.

    Full Text Available Congenital anterior tibiofemoral subluxation is an extremely rare disorder. All reported cases accompanied by other abnormalities and syndromes. A 16-year-old high school girl referred to us with bilateral anterior tibiofemoral subluxation as the knees were extended and reduced at more than 30 degrees flexion. Deformities were due to tightness of the iliotibial band and biceps femuris muscles and corrected by surgical release. Associated disorders included bilateral anterior shoulders dislocation, short metacarpals and metatarsals, and right calcaneuvalgus deformity.

    Full Text Available La familia Lamiaceae (labiatae labiadas, está formada por numerosas especies entre ellas el Rosmarinus officinalis L. La misma constituye una de las especies con mayor poder antioxidante por la presencia de sus aceites esenciales, monoterpenos y compuestos fenólicos. Su propagación vegetativa en Cuba es una de sus dificultades y en estos momentos se encuentra retirada del Formulario Nacional de Fitofármacos, debido a la disponibilidad en el país. El agua tratada magnéticamente ha sido muy utilizada en el riego ya que estimula el crecimiento y desarrollo de las plantas, mostrando que su aplicación puede activar el metabolismo de las células; sin embargo, los estudios han sido muy limitados en estos aspectos. El objetivo del trabajo fue evaluar los compuestos bioactivos monoterpenos presentes en la especie Rosmarinus officinalis L., cultivadas con agua tratada magnéticamente en Santiago de Cuba.

    Full Text Available Este trabajo propone un sistema experto basado en lógica difusa para apoyar la toma de decisiones en proyectos de reutilización de aguas residuales domésticas tratadas. La herramienta hidroinformática diseñada estima el potencial de reutilización de agua residual tratada a partir de factores como el índice de escasez y la eficiencia en DBO 5 de una planta de tratamiento de aguas residuales (PTAR. La herramienta fue validada a través de un caso de estudio en la PTAR del municipio de Nátaga, Huila, Colombia. En el caso de estudio, se utilizó el balance hídrico, análisis de calidad del agua y encuestas a expertos para establecer la estructura del sistema de lógica difusa, el cual fue implementado en Matlab ® . Los resultados indican una eficiencia del tratamiento de 88,7%, un índice de escasez de 28,5, que corresponde a un índice de escasez medio alto, y por tanto el sistema experto recomienda la reutilización de agua residual tratada con un 92,2%, lo que se clasifica como una reutilización confiable justificada. Se concluye que el sistema experto es adecuado para identificar fuentes alternas de recursos hídricos y esta información puede ayudar a los tomadores de decisiones en la implementación de políticas de gestión integral del recurso hídrico.

    Full Text Available OBJETIVO: Avaliar a influência de desigualdades sociais de ordem individual e contextual na experiência de cárie dentária não tratada em crianças no Brasil. MÉTODOS: Os dados sobre a prevalência de cárie dentária foram obtidos do Projeto Pesquisa Nacional de Saúde Bucal – SBBrasil 2010, levantamento epidemiológico de saúde bucal com amostra representativa para o país e cada uma de suas macrorregiões geográficas. Crianças de cinco anos de idade (n = 7.217 em 177 municípios foram examinadas e seus responsáveis responderam ao questionário. Características contextuais referentes aos municípios em 2010 (renda mediana, fluoretação da água e proporção de domicílios com abastecimento de água foram informadas pela Fundação Instituto Brasileiro de Geografia e Estatística. O estudo de associação utilizou modelos multinível de análise de regressão de Poisson. RESULTADOS: A prevalência de cárie não tratada foi de 48,2%; mais da metade da amostra apresentou ao menos um dente decíduo com experiência de cárie. O índice de cárie na dentição decídua ceo-d médio foi 2,41, sendo maior para as regiões Norte e Nordeste. Crianças de cor da pele preta e parda, e aquelas com renda familiar menos elevada tiveram maior prevalência de cárie não tratada. No nível contextual, renda mediana no município e adição de flúor na água de abastecimento associaram-se inversamente com a prevalência do desfecho. CONCLUSÕES: Desigualdades na prevalência de cárie não tratada persistem, afetando as crianças com dentição decídua no Brasil. O planejamento de medidas públicas para a promoção de saúde bucal deve considerar o efeito de fatores contextuais como determinante de riscos individuais.

    2005-01-01

    Full Text Available Although anterior cervical instrumentation was initially used in cervical trauma, because of obvious benefits, indications for its use have been expanded over time to degenerative cases as well as tumor and infection of the cervical spine. Along with a threefold increase in incidence of cervical fusion surgery, implant designs have evolved over the last three decades. Observation of graft subsidence and phenomenon of stress shielding led to the development of the new generation dynamic anterior cervical plating systems. Anterior cervical plating does not conclusively improve clinical outcome of the patients, but certainly enhances the efficacy of autograft and allograft fusion and lessens the rate of pseudoarthrosis and kyphosis after multilevel discectomy and fusions. A review of biomechanics, surgical technique, indications, complications and results of various anterior cervical plating systems is presented here to enable clinicians to select the appropriate construct design.

  5. Intradural anterior transpetrosal approach.

    The standard anterior transpetrosal approach (ATPA) for petroclival lesions is fundamentally an epidural approach and has been practiced for many decades quite successfully. However, this approach has some disadvantages, such as epidural venous bleeding around foramen ovale. We describe here our experience with a modified technique for anterior petrosectomy via an intradural approach that overcomes these disadvantages. Five patients with petroclival lesions underwent surgery via the intradural ATPA. The intraoperative hallmarks are detailed, and surgical results are reported. Total removal of the lesions was achieved in two patients with petroclival meningioma and two patients with pontine cavernoma, whereas subtotal removal was achieved in one patient with petroclival meningioma without significant morbidity. No patient experienced cerebrospinal fluid leakage. The intradural approach is allowed to tailor the extent of anterior petrosectomy to the individually required exposure, and the surgical procedure appeared to be more straightforward than via the epidural route. Caveats encountered with the approach were the temporal basal veins that could be spared as well as identification of the petrous apex due to the lack of familial epidural landmarks. The risk of injury to the temporal bridging veins is higher in this approach than in the epidural approach. Intradural approach is recommended in patients with a large epidural venous route, such as sphenobasal and sphenopetrosal vein. Navigation via bone-window computed tomography is useful to identify the petrous apex.

    Anterior knee pain is a common complain in all ages athletes. It may be caused by a large variety of injuries. There is a continuum of diagnoses and most of the disorders are closely related. Repeated minor trauma and overuse play an important role for the development of lesions in Hoffa's pad, extensor mechanism, lateral and medial restrain structures or cartilage surface, however usually an increase or change of activity is referred. Although the direct relation of cartilage lesions, especially chondral, and pain is a subject of debate these lesions may be responsible of early osteoarthrosis and can determine athlete's prognosis. The anatomy and biomechanics of patellofemoral joint is complex and symptoms are often unspecific. Transient patellar dislocation has MR distinct features that provide evidence of prior dislocation and rules our complication. However, anterior knee pain more often is related to overuse and repeated minor trauma. Patella and quadriceps tendon have been also implicated in anterior knee pain, as well as lateral or medial restraint structures and Hoffa's pad. US and MR are excellent tools for the diagnosis of superficial tendons, the advantage of MR is that permits to rule out other sources of intraarticular derangements. Due to the complex anatomy and biomechanic of patellofemoral joint maltracking is not fully understood; plain films and CT allow the study of malalignment, new CT and MR kinematic studies have promising results but further studies are needed. Our purpose here is to describe how imaging techniques can be helpful in precisely defining the origin of the patient's complaint and thus improve understanding and management of these injuries.

Esta investigación se realizó entre febrero y marzo del 2012 en el Centro de Investigaciones Agronómicas, Sabanilla, San José, Costa Rica. Se utilizó un diseño completamente al azar con cuatro repeticiones y ocho plantas por unidad experimental en un arreglo factorial con los factores de dosis (0, 25% y 50% v/v vermicompost:suelo e inoculación (0 y 500 zoosporas por gramo de suelo. Se trasplantaron plántulas de 35 días, que fueron inoculadas dos semanas después del trasplante. La aplicación de vermicompost provocó un aumento significativo del peso fresco foliar y del peso seco foliar y radical; a mayor dosis, mayor fue el incremento. Las plantas de todos los tratamientos que incluyeron inoculación con P. capsici presentaron síntomas de la enfermedad en la raíz. Los valores de incidencia y severidad fueron mayores para el tratamiento con 50% de abono. En este tratamiento se presentaron síntomas de marchitez. La ausencia de diferencias en las variables de peso fresco y seco entre los tratamientos inoculados y sin inocular, a los que se adicionó abono al 25%, sugiere que esta dosis podría compensar el daño causado por el patógeno. Se observó una menor concentración de nutrimentos en los tejidos de las plantas inoculadas lo que indica que el daño causado a la raíz pudo haber afectado la adquisición de nutrimentos.

Patients with diffuse anterior retinoblastoma are older than those with the classical types, with the mean age being 6.1 years. The original cells of diffuse anterior retinoblastoma are supposed to be cone precursor. Patients most commonly present with pseudouveitis, pseudohypopyon, and increased intraocular pressure. The retina under fundus examination is likely to be normal, and the clinical features mimic the inflammation progress, which can often lead to misdiagnosis. The published diffuse anterior retinoblastoma cases were diagnosed after fine-needle aspiration biopsy running the potential risk of inducing metastasis. The most common treatment for diffuse anterior retinoblastoma is enucleation followed by systematic chemotherapy according to the patient’s presentation and clinical course. This review summarizes the recent advances in etiology (including tumorigenesis and cell origin, pathology, diagnosis, differential diagnosis, and new treatment. The challenges of early diagnosis and prospects are also discussed. Keywords: pathology, microenvironment, treatment, diagnosis

    Full Text Available Objetivo: apresentar os aspectos clínicos, diagnósticos e terapêuticos de pacientes portadores de válvula da uretra anterior. Descrição: em dois neonatos, o diagnóstico presuntivo de patologia obstrutiva do trato urinário foi sugerido pela ultra-sonografia realizada no período pré-natal, confirmando-se o diagnóstico de válvula de uretra anterior pela avaliação pós-natal. Os pacientes foram submetidos a tratamento cirúrgico paliativo, com vesicostomia temporária e, posteriormente, definitivo, pela fulguração endoscópica das válvulas. Ambos evoluíram com função renal normal. Comentários: a válvula da uretra anterior é anomalia rara que deve ser considerada em meninos com quadro radiológico pré-natal sugestivo de obstrução infravesical, secundariamente à hipótese mais comum de válvula da uretra posterior. Ressaltamos a utilização da vesicostomia como derivação urinária temporária nestes casos, prevenindo potenciais complicações pela manipulação da uretra do recém-nascido.Objective: to discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. Description: signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was performed in both patients. Later, the valves were fulgurated using an endoscopic procedure. During the follow-up period both patients presented normal renal function. Comments: anterior urethral valves are a rare form of urethral anomaly that must be ruled out in boys with pre-natal ultrasound indicating infravesical obstruction. Vesicostomy used as an initial treatment rather than transurethral fulguration may prevent potential complications that can occur due to the small size of the neonatal urethra.

    Full Text Available ResumoO aproveitamento do nitrogênio aplicado em cobertura na forma de ureia é muito baixo, pois esta forma de adubo sofre grandes perdas por lixiviação, desnitrificação e principalmente por volatilização. É sabido que o processo de volatilização caracteriza-se pela hidrólise da ureia por meio da enzima urease, que é produzida por bactérias e fungos do solo e, que a quantificação da atividade da enzima urease nos fornece uma indicação do potencial do solo em converter nitrogênio orgânico em mineral e, por estar ligada à atividade microbiana os fatores como concentração do substrato, umidade, temperatura e pH do solo afetam a atividade enzimática do solo. Uma alternativa para minimizar as perdas de nitrogênio por volatilização é o tratamento prévio da ureia com inibidores da urease, a qual proporciona diminuição nas perdas de NH3 volatilizado, pois ela atua ocupando o local ativo da enzima urease, que é responsável pela hidrólise da ureia e, dentre os produtos testados o NBPT [N-(n-butil tiofosfórico triamida], tem demonstrado boa eficiência na redução das perdas. Dessa forma, o presente trabalho tem por objetivo fazer uma revisão de literatura sobre as possíveis perdas de nitrogênio do fertilizante na forma de ureia e aspectos agronômicos da ureia tratada com inibidor de urease.

    Full Text Available Se caracteriza la mezcla de poliamina alifática comercial con sacarosa, zeolita y composites con aluminio, bronce y hierro, así como mezclas de éstos con resinas furano epoxídicas (FAM, tratadas con y sin calor, mediante espectroscopía FTIR. La caracterización se comienza por la asignación de los espectros IR de cada uno de los componentes de la mezcla y se muestran las posiciones de las bandas con las asignaciones de las frecuencias características más importantes de los componentes que cumplen con la estructura química planteada. Del análisis de los espectros IR se reporta la desaparición de la banda de vibración de streching de la amina primaria y se mantiene la banda de vibración de streching del grupo OH 3350 cm-1 con baja intensidad, lo que evidencia una reacción química con los grupos aminos y OH, pero se observa C-N. Se mantienen las bandas con frecuencia características del anillo furánico y la estructura cíclica de la sacarosa. El tratamiento con calor, aparentemente, no influye sobre la estructura molecular de la mezcla.

    Full Text Available Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondiloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the “activity” of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

    2002-01-01

    Full Text Available Introduction The aim of this paper was to present methods of placement of artificial anterior teeth in edentulous individuals. The following review takes account of the majority of papers published during the last 100 years. The review has been divided into sections regarding the method used to determine the position of artificial anterior teeth. Geometric aspect Gysi (1895-1920 produced the first scientific theory about the position of artificial anterior teeth. Physiognomic theory The aim of this theory is to find the most natural position for artificial anterior teeth for each individual. Camper's "face angle" as a physiognomic criterion, has been introduced in papers of Wehrli (1961, Marxhors (1966, Tanzer (1968, Lombardi (1973. Esthetic aspect Important names in the field of dental esthetics are: Schön and Singer (1961, Arnheim (1965, Krajiček (1969, Tanzer (1968, Lombardi (1973, Goldstein (1976. They have introduced principles of visual aspects for selection of contours, dimension and position of artificial anterior teeth. Constitution aspect Flagg (1880, Williams (1913 and Hrauf (1957, 1958, have considered body constitution and individual characteristics regarding position of artificial anterior teeth. Physiological theory In 1971, Marxhors pointed to the fact that the position of artificial teeth corresponds with the function of the surrounding soft tissue and from the aspect of physiognomy as well. Phonetic aspect According to Silverman (1962 artificial anterior teeth are nearest when we pronounce the sound "S". Cephalometrical research Rayson (1970, Watson (1989, Strajnić Lj. (1999, Bassi F. (2001 have presented cephalometric radiographic analyses of natural anterior teeth compared with cephalometric radiographic analyses of artificial anterior teeth. A review of dental literature shows several factors suggesting modalities which should determine the position of artificial anterior teeth. Numerous methods have been designed for

    Full Text Available Toxic anterior segment syndrome (TASS is a sterile intraocular inflammation caused by noninfectious substances, resulting in extensive toxic damage to the intraocular tissues. Possible etiologic factors of TASS include surgical trauma, bacterial endotoxin, intraocular solutions with inappropriate pH and osmolality, preservatives, denatured ophthalmic viscosurgical devices (OVD, inadequate sterilization, cleaning and rinsing of surgical devices, intraocular lenses, polishing and sterilizing compounds which are related to intraocular lenses. The characteristic signs and symptoms such as blurred vision, corneal edema, hypopyon and nonreactive pupil usually occur 24 hours after the cataract surgery. The differential diagnosis of TASS from infectious endophthalmitis is important. The main treatment for TASS formation is prevention. TASS is a cataract surgery complication that is more commonly seen nowadays. In this article, the possible underlying causes as well as treatment and prevention methods of TASS are summarized.

    Anterior cervical hypertrichosis is a very rare form of primary localized hypertrichosis. It consists of a tuft of terminal hair on the anterior neck just above the laryngeal prominence. The etiology is still unknown. In this article, we reported a 15-year-old female patient who presented to our clinic with a complaint of hypertrichosis on the anterior aspect of the neck for the last five years. Her past medical history revealed no pathology except for vesicoureteral reflux. On the basis of clinical presentation, our patient was diagnosed with anterior cervical hypertrichosis and she was considered to be a sporadic case due to lack of other similar cases in familial history. To date, 33 patients with anterior cervical hypertrichosis have been reported. Anterior cervical hypertrichosis can be associated with other abnormalities, but it frequently presents as an isolated defect (70%). The association of vesicoureteral reflux and anterior cervical hypertrichosis which was observed in our patient might be coincidental. So far, no case of anterior cervical hypertrichosis associated with vesicoureteral reflux has been reported in the literature.

    In deformity surgery, anterior lumbar interbody fusion provides excellent biomechanical support, creates a broad surface area for arthrodesis, and induces lordosis in the lower lumbar spine. Preoperative MRI, plain radiographs, and, when available, CT scan should be carefully assessed for sacral slope as it relates to pubic symphysis, position of the great vessels (especially at L4/5), disc space height, or contraindication to an anterior approach. This video demonstrates the steps in an anterior surgical procedure with minimal open exposure. The video can be found here: https://youtu.be/r3bC4_vu1hQ .

    Conclusions This technique is offered as a convenient and reliable method for cases with anterior TM perforation and inadequate anterior remnant. Objectives Chronic otitis media surgery is one of the most common procedures in otology. Anterior tympanic membrane (TM) perforation with inadequate anterior remnant is associated with higher rates of graft failure. It was the goal of this series to evaluate the anatomical and functional outcomes of a modified underlay myringoplasty technique-the anterior pull-through method. Materials and methods In a retrospective clinical study, 13 patients with anterior TM perforations with inadequate anterior remnants underwent tympanoplasty with anterior pull-through technique. The anterior tip of the temporalis fascia was pulled through and secured in a short incision lateral to the anterior part of the annulus. Data on graft take rate, pre-operative, and post-operative hearing status were analyzed. Results A graft success rate of 84.6% (11 out of 13) was achieved, without lateralization, blunting, atelectasia, or epithelial pearls. The air-bone gap was 21.5 ± 6.8 dB before intervention and 11.75 ± 5.7 dB after surgery (p = 0.003).

    The proposed skiing injury mechanism that suggests a quadriceps muscle contraction can contribute to anterior cruciate ligament rupture was biomechanically investigated. The effect of quadriceps muscle force on a knee specimen loaded to anterior cruciate ligament failure during anterior tibial translation was studied in a human cadaveric model. In both knees from six donors, average age 41 years (range, 31 to 65), the joint capsule and ligaments, except the anterior cruciate ligament, were cut. The quadriceps tendon, patella, patellar tendon, and menisci were left intact. One knee from each pair was randomly selected to undergo destructive testing of the anterior cruciate ligament by anterior tibial translation at a displacement rate of 30 mm/sec with a simultaneously applied 889 N quadriceps muscle force. The knee flexion during testing was 30 degrees. As a control, the contralateral knee was loaded correspondingly, but only 5 N of quadriceps muscle force was applied. The ultimate load for the knee to anterior cruciate ligament failure when tested with 889 N quadriceps muscle force was 22% +/- 18% higher than that of knees tested with 5 N of force. The linear stiffness increased by 43% +/- 30%. These results did not support the speculation that a quadriceps muscle contraction contributes to anterior cruciate ligament failure. In this model, the quadriceps muscle force protected the anterior cruciate ligament from injury during anterior tibial translation.

    Full Text Available El 5-fluorouracilo es un antineoplásico usado en la terapia del cáncer y posee acción inmunosupresora al inhibir la proliferación de células del tejido hematopoyético. En este trabajo se evaluó el efecto inmunomodulador de la solución CM-95 tratada magnéticamente en ratones Balb/c inoculados con 5-fluorouracilo a través de su acción protectora rehabilitadora sobre parámetros celulares y tisulares del tejido hematopoyético. A los ratones, entre 20-22 g de peso y 6 semanas de nacidos, se les administró esta solución CM-95 tratada magnéticamente por vía intraperitoneal en un esquema de dos inoculaciones; luego se administró por la misma vía el 5_fluorouracilo a una dosis de 150 mg/m2 de superficie corporal de cada ratón. Se evaluó el conteo total y diferencial de leucocitos antes de inocular el 5-fluorouracilo, y a los tres y siete días de aplicado este. La celularidad de médula ósea y bazo y la observación microscópica del corte histológico de hígado y bazo por la técnica de inclusión en parafina y tinción con eosina hematoxilina al 10% se evaluaron a los siete días de haber aplicado el 5- fluorouracilo. La solución CM-95, tratada magnéticamente, logró modular los efectos del 5-fluorouracilo con una actividad protectora rehabiltadora, para los parámetros evaluados en médula ósea, sangre periférica, bazo e hígado. Estos resultados abren nuevas perspectivas para la aplicación del sistema acuoso tratado magnéticamente como inmunomodulador.

    The clinical features of 290 children with anterior uveitis are presented. The vast majority suffered from chronic uveitis. Specific uveitis entities in children include the syndrome of 'chronic iridocyclitis' in girls, heterochromic cyclitis, and pars planitis. Systemic associations include sarcoidosis, the Vogt-Harada-Koyanagi syndrome, and the seronegative arthritides (juvenile chronic arthritis, juvenile ankylosing spondylitis, psoriatic arthritis, and rarely Reiter's and Beçet's syndromes). Children with a pauciarticular onset of juvenile chronic arthritis, especially when combined with positive findings for antinuclear antibody, are at particular risk of developing chronic anterior uveitis. Most cases of chronic anterior uveitis can be controlled with topical corticosteroids. Those that are resistant to both topical and systemic corticosteroids may have to be treated with chlorambucil. The operation of lensectomy is a great advance in the management of complicated cataract. Secondary glaucoma is the most devastating complication of chronic anterior uveitis in children and responds poorly to therapy.

    Full Text Available Objective To study the ideal patient's head positioning for the anterior circulation aneurysms microsurgery. Method We divided the study in two parts. Firstly, 10 fresh cadaveric heads were positioned and dissected in order to ideally expose the anterior circulation aneurysm sites. Afterwards, 110 patients were submitted to anterior circulation aneurysms microsurgery. During the surgery, the patient's head was positioned accordingly to the aneurysm location and the results from the cadaveric study. The effectiveness of the position was noted. Results We could determine mainly two patterns for head positioning for the anterior circulation aneurysms. Conclusion The best surgical exposure is related to specific head positions. The proper angle of microscopic view may minimize neurovascular injury and brain retraction.

    The authors report the case of a 68-year-old woman with secondary adenocarcinoma of the lungs from an unknown primary. Erlotinib was started which produced symptoms suggestive of uveitis. Erlotinib was stopped and restarted a month later at a lower dose, which resulted in severe bilateral anterior uveitis. The uveitis settled after stopping erlotinib and treatment with topical steroids and cycloplegics. To the best of the authors’ knowledge, this is the first case of erlotinib-related anterior uveitis.

  14. Anterior Eye Imaging with Optical Coherence Tomography

    Science.gov (United States)

    Huang, David; Li, Yan; Tang, Maolong

    The development of corneal and anterior segment optical coherence tomography (OCT) technology has advanced rapidly in recently years. The scan geometry and imaging wavelength are both important choices to make in designing anterior segment OCT systems. Rectangular scan geometry offers the least image distortion and is now used in most anterior OCT systems. The wavelength of OCT light source affects resolution and penetration. An optimal choice of the OCT imaging wavelength (840, 1,050, or 1,310 nm) depends on the application of interest. Newer generation Fourier-domain OCT technology can provide scan speed 100-1000 times faster than the time-domain technology. Various commercial anterior OCT systems are available on the market. A wide spectrum of diagnostic and surgical applications using anterior segment OCT had been investigated, including mapping of corneal and epithelial thicknesses, keratoconus screening, measuring corneal refractive power, corneal surgery planning and evaluation in LASIK, intracorneal ring implantation, assessment of angle closure glaucoma, anterior chamber biometry and intraocular lens implants, intraocular lens power calculation, and eye bank donor cornea screening.

  17. Selección de cartera mediante escenarios con dotación inicial indeterminada

    Ventura Marco, M.

    1999-01-01

    Full Text Available Los modelos media-varianza de selección de cartera, y en general los basados en el binomio rentabilidad-riesgo, parten de un capital inicial cierto. La consideración de la aversión al riesgo en los mismos es indirecta y siempre referida al valor final de la cartera, así que por lo general lo que se determina en los mismos es la proporción de la inversión total o riqueza inicial que se destina a cada activo considerado. Sin embargo, en muchas situaciones reales la aversión al riesgo debe considerarse ya en el momento de invertir, por lo que la determinación de la cuantía a invertir, coste o dotación inicial forma parte del problema, considerando que será mayor, dentro de unas cotas, si existe la probabilidad de obtener mayor rentabilidad aún soportando mayor riesgo. El problema se presenta mediante un modelo simple, pero general en su planteamiento, en el que además de la composición de la cartera queda determinada la cantidad a invertir. La idea es que el inversor establece dos capitales, uno como mínimo y otro como máximo, que está dispuesto a invertir y se utiliza la optimización por escenarios para decidir qué cantidad, entre las dos anteriores, le conviene invertir según sus expectativas.

    The mediastinum is located from the thoracic inlet to the diaphragm between the left and right pleural cavities and contains vital structures of the circulatory, respiratory, digestive, and nervous system. Over the years, since there are no fascial or anatomic planes, anatomists and radiologists have suggested various schemes for subdividing the mediastinum and several anatomical and radiological classifications of the mediastinum are reported in the literature. The most popular of these scheme divides medistinum, for purposes of description, into two parts: an upper portion, above the upper level of the pericardium, which is named the superior mediastinum; and a lower portion, below the upper level of the pericardium. For clinical purposes, the mediastinum may be subdivided into three major areas, i.e. anterior, middle, and posterior compartments. The anterior mediastinum is defined as the region posterior to the sternum and anterior to the heart and brachiocephalic vessels. It extends from the thoracic inlet to the diaphragm and contains the thymus gland, fat, and lymph nodes. This article will review surgical anatomy of the anterior mediastinum and will focus on the surgical approch to anterior mediastinum and thymic diseases.

    Full Text Available Se estudió la influencia del tratamiento a pH ácido de aislados proteicos de soja sobre las propiedades espumantes mediante el análisis de las constantes cinéticas de desproporción y drenado y el relacionamiento de éstas con los parámetros de reología interfacial. Los aislados proteicos de soja fueron obtenidos a partir de harina desgrasada. Una porción se llevó a pH 8,0 y otra porción se trató a pH 2,0. De la porción a pH 2,0 una parte se dejó a este pH y otra parte se neutralizó a pH 8,0. Todas las porciones se liofilizaron. Para la identificación y caracterización estructural de las muestras se realizaron análisis de electroforesis desnaturalizante, calorimetría diferencial de barrido, solubilidad e hidrofobicidad superficial. Se obtuvieron espumas por el método de burbujeo de gas. Se determinó la velocidad inicial de pasaje de líquido a la espuma y el volumen máximo de líquido incorporado a la espuma. El proceso de desestabilización de las espumas formadas se analizó ajustando los datos obtenidos a una cinética de segundo orden bifásica. Se realizaron estudios de reología interfacial con un tensiómetro de gota. El tratamiento a pH ácido mejoró tanto la espumabilidad como la estabilidad de las espumas. La proporción de líquido drenado por escurrido gravitatorio fue significativamente superior al volumen drenado debido a la desproporción. El tratamiento a pH 2,0 redujo la desestabilización por desproporción de Ostwald, lo que sugiere la formación en la interfase de una película más cohesiva, que se confirma con los parámetros de reologíainterfacial.

    Full Text Available A clinical case with anterior open-bite, treated in the mixed dentition, is presented. This approach demonstrates one of the possible approaches of treatment, which is capable of interfering with growth and redirecting its vectors. Orthodontic and orthopedic methods were used, consisting of slow maxillary expansion, through a fixed palatal crib soldered in a bi-helix appliance, and high-pull traction on the mandible for 16 hours a day. After eight years of follow-up, stable outcomes were accomplished. These results may be explained by the fact that treatments were performed at the appropriate period of development, thus establishing perioral muscular equilibrium, matching the final period of facial growth. The combination of orthodontic and orthopedic treatments was necessary to prevent the need of further orthognathic surgery treatment.Apresentou-se um relato de caso clínico de mordida aberta anterior, tratada em dentadura mista, demonstrando uma das possíveis formas de tratamento, capaz de interferir no crescimento e redirecionar seus vetores. Os protocolos ortodônticos e ortopédicos utilizados foram a expansão lenta da maxila, utilizando grade palatina soldada a um expansor bihélice, com tração alta na mandíbula, num período diário de 16 horas. Oito anos de estabilidade foram alcançados, explicados pelo fato de o tratamento ter sido conduzido no momento oportuno do desenvolvimento, o que estabeleceu equilíbrio entre os músculos peribucais, em conjunto com o período final do crescimento. A combinação do tratamento ortodôntico e ortopédico foi necessária para se evitar a necessidade de tratamento cirúrgico.

    Full Text Available Thymolipoma is a rare benign tumor of anterior mediastinum, described by Lange in 1916. 1 Less than 200 cases have been reported worldwide. 2 It accounts for 2% to 9% of thymic tumours. 3 We report a case of thymolipoma in a 37 year s old male patient, who pre sented with cough, dys p nea, chest pain for 2 months. CT THORAX revealed a large anterior mediastinal mass extending in to right hemithorax arising from thymus gland, with multiple areas of fat density, no significant mediastinal adenopathy, complete collap se of right middle and lower lobe suggestive of thymolipoma. CT guided biopsy suggestive of thymic neoplasm. The tumour was removed enbloc through surgery. Histopathological examination of large mass lesion confirmed thymolipoma. We report this case to emp hasize the importance of considering thymolipoma as a differential diagnosis of anterior mediastinal mass, although rare.

  3. Esthetic crown lengthening for maxillary anterior teeth.

    1997-08-01

    In the maxillary anterior region, the gingival labial margin position is an important parameter in the achievement of an ideal smile. The relationship between the periodontium and the restoration is critical if gingival health and esthetics are to be achieved. Periodontal therapy is a necessary and useful adjunct when any anterior restoration is undertaken. Anterior surgical crown lengthening may be undertaken to avoid restorative margin impingement on the biologic width. Crown lengthening is also used to alter the gingival labial profiles. This article discusses the esthetic parameters of ideal gingival labial positions and presents a classification of crown-lengthening procedures and the procedure for a two-stage crown-lengthening technique. The two-stage crown-lengthening technique is surgically precise because healing is predictable.

    Full Text Available Michelle Chen Lynch,1 Andrew B Mick21Optometry Clinic, Ocala West Veterans Affairs Specialty Clinic, Ocala, FL, USA; 2Eye Clinic, San Francisco VA Medical Center, San Francisco, CA, USABackground: Anterior scleritis is an uncommon form of ocular inflammation, often associated with coexisting autoimmune disease. With early recognition and aggressive systemic therapy, prognosis for resolution is good. The diagnosis of underlying autoimmune disease involves a multidisciplinary approach.Case report: A 42-year-old African American female presented to the Eye Clinic at the San Francisco Veteran Affairs Medical Center, with a tremendously painful left eye, worse on eye movement, with marked injection of conjunctiva. There was mild swelling of the upper eyelid. Visual acuity was unaffected, but there was a mild red cap desaturation. The posterior segment was unremarkable. The initial differential diagnoses included anterior scleritis and orbital inflammatory disease. Oral steroid treatment was initiated with rapid resolution over a few days. Orbital imaging was unremarkable, and extensive laboratory work-up was positive only for antinuclear antibodies. The patient was diagnosed with idiopathic diffuse, nonnecrotizing anterior scleritis and has been followed for over 5 years without recurrence. The rheumatology clinic monitors the patient closely, as suspicion remains for potential arthralgias including human leukocyte antigen-B27-associated arthritis, lupus-associated arthritis, seronegative rheumatoid arthritis, recurrent juvenile idiopathic arthritis, and scleroderma, based on her constitutional symptoms and clinical presentation, along with a positive anti-nuclear antibody lab result.Conclusion: Untreated anterior scleritis can progress to formation of cataracts, glaucoma, uveitis, corneal melting, and posterior segment disease with significant risk of vision loss. Patients with anterior scleritis must be aggressively treated with systemic anti

    Dengue fever is caused by a flavivirus. This infection is endemic in the tropics and warm temperate regions of the world. Ocular manifestations of dengue fever include subconjunctival, vitreous, and retinal haemorrhages; posterior uveitis; optic neuritis; and maculopathies, haemorrhage, and oedema. However anterior ischemic optic neuropathy is a rare presentation. Optic nerve ischemia most frequently occurs at the optic nerve head, where structural crowding of nerve fibers and reduction of the vascular supply may combine to impair perfusion to a critical degree and produce optic disc oedema. Here we present a case of anterior ischemic optic neurapathy associated with dengue fever.

    Full Text Available Aetiological diagnosis of anterior uveitis was made clinically and substantiated with relevant investigations. Aqueous humour obtained under aseptic conditions, was analyzed for the cells study, culture and protein profile, using polyacrylamide gel electrophoresis. The results were analysed with the help of known clinical facts. Culture and smears were invariably negative, while the lymphocytes were present in varying numbers, polymorphs and macrophages afforded a useful clue for confirmatory diagnosis. The electrophoretic pattern of the proteins was related to the duration of the disease and was same in a group while it was distinctive among different groups of anterior uveitis.

    2011-06-01

    Full Text Available Radiologist always examines X-ray to determine abnormal changes in cervical, lumbar & thoracic vertebrae. Osteophyte (bony growth may appear at the corners of vertebrae so that vertebral shape becomes abnormal. This paper presents the idea from Image processing techniques such as customised Hough transform which will be used for segmentation which should be independent of rotation, scale, noise & shape. This segmented image will be then used for computing size invariant, convex hull based features to differentiate normal cervical vertebrae from cervical vertebrae containing anterior osteophyte. This approach effectively finds anterior osteophytes in cervical vertebrae.

    Full Text Available Congenital coronary artery anomalies are uncommon. Dual left anterior descending coronary artery (LAD is defined as the presence of two LADs within the anterior interventricular sulcus (AIVS, and is classified into four types. Type IV is a rarely reported subtype and differs from the others, with a long LAD originating from the right coronary artery (RCA. Dual LAD is a benign coronary artery anomaly, but should be recognised especially before interventional procedures. With the increasing use of multidedector computed tomography (MDCT, it is essential for radiologists to be aware of this entity and the cross-sectional findings.

    Full Text Available A regulação da atividade do ciclo estral dos mamí¬feros domésticos é um processo complexo e está, basica¬mente, sob o controle do eixo hipotálamo-adenohipófise-ovários, através de mecanismos endócrinos e neuroendócri¬nos. A progesterona constitui-se em importante regulador da atividade funcional e estrutural do sistema reprodutor das fêmeas domésticas. Considerando-se sua importância e sua freqüente utilização, realizou-se o presente trabalho, que teve por objetivo avaliar os aspectos citopatológicos da vagina de camundongas tratadas com progesterona. Foram utilizadas 36 camundongas da linhagem Swiss Webster di¬vididas em quatro grupos e submetidas aos seguintes pro¬cedimentos: Grupo S (controle – camundongas tratadas com o veículo e avaliadas durante quinze dias consecuti¬vos; Grupos E1, E2 e E3 (camundongas tratadas com 0,375 mg, 0,75 mg e 1,5 mg de acetato de medroxiprogesterona respectivamente e avaliadas durante quinze dias de experi¬mento. De acordo com os resultados obtidos pode-se con¬cluir que o acetato de medroxiprogesterona em dose única de 0,75 ou 1,5 mg predispõe a interrupção do cliclo estral e o aumento do número de leucócitos no colpocitológico de camundongas. PALAVRAS-CHAVES: Bloqueio do ciclo estral, ciclo estral, colpocitologia, medroxiprogesterona. The domestic mammal’s estrus cycle regulation is a complex process, controlled by hypothalamus-adenohy¬pofisis-ovary axis, through endocrine and neuroendocrine mechanisms. The use of progesterone hormone is an im¬portant way to regulate the functional and structural female reproductive tract activity. Considering the frequent pro¬gesterone usage and its importance, we intended to study the vagina citopathologycal aspects of female mice treated with progesterone. We used thirty six Swiss Webster female mice. These animals were divided in four groups: S Group (control group- female mice treated with vehicle and valued during fifteen days

    Full Text Available In order to prevent anterior cruciate ligament injuries it is necessary to define risk factors and to analyze the most frequent causes of injuries - that being the aim of this study. The study sample consisted of 451 surgically treated patients, including 400 sportsmen (65% of them being active and 35% recreational sportsmen, 29% female and 71% male; of whom 90% were younger than 35. Sports injuries, as the most frequent cause of anterior cruciate ligament injuries, were recorded in 88% of patients (non-contact ones in 78% and contact ones in 22%, injuries occurring in everyday activities in 11% and in traffic in 1%. Among sportsmen, reconstruction of the anterior cruciate ligament was most frequently performed in football players (48%, then in handball players (22%, basketball players (13%, volleyball players (8%, martial arts fighters (4%. However, the injury incidence was the highest among the active basketball players (1 injured among 91 active players. Type of footwear, warming up before the activity, genetic predisposition and everyday therapy did not have a significant influence on getting injured. Anterior cruciate ligament injuries happened three times more often during matches, in the middle and at the end of a match and training session (79%, at landing after the jump or when changing direction of movement (75% without a contact with other competitors, on dry surfaces (79%, among not so well prepared sportsmen.

    Full Text Available Leishmaniasis infection may involve destruction of nasal tissues resulting in lacrimal drainage system alteration. PURPOSE: To evaluate the frequency of lacrimal excretory system sequelae in patients treated for leishmaniasis. METHODS: Forty-five leishmaniasis-treated patients (90 nasolacrimal ducts were submitted to lacrimal excretory system evaluation. All were evaluated by Jones I test and when it was abnormal, dacryocystography and nasal endoscopy were performed. This situation occurred in 13 patients (26 nasolacrimal ducts. RESULTS: The majority of evaluated patients had the cutaneous form (64.4% of leishmaniasis, however, 69.23% of the patients with lacrimal excretory system alterations had the mucocutaneous form of infection before treatment. In these, the most common alteration detected was bilateral permeable and dilated nasolacrimal ducts (92.30%. Only 3.84% (1/26 of the evaluated nasolacrimal ducts were obstructed. Nasal endoscopy showed turbinate hypertrophy (53.84%, septum deviation (53.84% and nasal septum perforation (23.07%. CONCLUSION: Permeable and dilated lacrimal excretory system were the most common sequelae related to leishmaniasis infection.A leishmaniose pode destruir os tecidos nasais resultando em alterações da via lacrimal excretora.

    Full Text Available Anterior teeth movement in orthodontic treatment is limited to labiolingual direction by very thin alveolar bone. An uncontrolled anterior tooth movement to labiolingual direction can cause alveolar bone perforation at its root segment. This case report is to remind us that alveolar bone thickness limits orthodontc tooth movement. A case of crowded anterior teeth with thin alveolar bone in malocclusion I is reported. This case is treated using adgewise orthodontic appliance. Protraction of anterior teeth is anticipated due to thin alveolar bone on the anterior surface. The conclusion is although the alveolar bone surrounding the crowded anterior teeth is thin, by controlling the movement the teeth reposition is allowed.

    Full Text Available Uveitis is composed of a diverse group of disease entities, which in total has been estimated to cause approximately 10% of blindness. Uveitis is broadly classified into anterior, intermediate, posterior and panuveitis based on the anatomical involvement of the eye. Anterior uveitis is, however, the commonest form of uveitis with varying incidences reported in worldwide literature. Anterior uveitis can be very benign to present with but often can lead to severe morbidity if not treated appropriately. The present article will assist ophthalmologists in accurately diagnosing anterior uveitis, improving the quality of care rendered to patients with anterior uveitis, minimizing the adverse effects of anterior uveitis, developing a decision-making strategy for management of patients at risk of permanent visual loss from anterior uveitis, informing and educating patients and other healthcare practitioners about the visual complications, risk factors, and treatment options associated with anterior uveitis.

    2012-12-01

    Full Text Available This article presents a case of anterior diffuse scleritis that initially was diagnosed as conjunctivitis. Anterior diffuse scleritis (ADS is a potentially vision-threatening inflammation of the sclera whose etiology may include autoimmune and systemic conditions such as rheumatoid arthritis and tuberculosis. The signs and symptoms of ADS include pain, tearing, tenderness, redness, painful sensitivity to light and decreased visual acuity. Ocular and physical examinations including blood tests to rule out underlying causes are important. Medications such as corticosteroids, non-steroidal anti-inflam-matory drugs and possibly immune-suppressants are used in the management of ADS. If care is not taken, ADS can be mis-diagnosed as conjunctivitis because the redness is similar in both conditions. Such mis-diagnosis can be sight-threatening and therefore it is essential that primary eye care practitioners are cautious in all diagnoses of red eye conditions. (S Afr Optom 2012 71(1 51-54

  15. Cataract Surgery in Anterior Megalophthalmos: A Review

    GALVIS, Virgilio; TELLO, Alejandro; M. RANGEL, Carlos

    2015-01-01

    Anterior megalophthalmos is characterized by megalocornea associated with a very broad anterior chamber and ciliary ring elongation. It is also called X-linked megalocornea. It is accompanied by early development of cataracts, zonular anomalies, and, rarely, vitreoretinal disorders. Subluxation of a cataract can occur in cataract surgery because of zonular weakness. In addition, in most patients, standard intraocular lens (IOL) decentration is a risk because of the enlarged sulcus and capsular bag. These unique circumstances make cataract surgery challenging. To date, several approaches have been developed. Implantation of a retropupillary iris-claw aphakic intraocular lens may be a good option because it is easier than suturing the IOL and can have better and more stable anatomic and visual outcomes, compared to other techniques.

    2013-04-01

    Esthetic treatment of primary teeth is one of the greatest challenges to pediatric dentists. A variety of restorative options using full coverage are available for anterior primary teeth. In the last half century the emphasis on treatment of severely decayed primary teeth shifted from extraction to restoration. In the past, restorations consisted of placement of stainless steel crowns on severely decayed teeth. However, they are esthetically unacceptable today. Over the last decade parents expect a higher esthetic standard for their children's primary teeth. Thus, the restoration should provide esthetic appearance and durability in addition to restoring function. The purpose of this review is to describe the types of full coverage options for anterior primary teeth currently available.

    In the acute setting, accurate radiological interpretation of paediatric cervical spine trauma can be difficult due to a combination of normal variants and presence of multiple synchondroses. We present a rare case of a fracture through the anterior atlantal synchondrosis in a paediatric spine. A five-year-old boy, who fell backwards onto the top of his head while swinging across on a monkey bar frame, presented with neck pain, cervical muscle spasm and decreased right lateral rotation and extension of his neck. Computed tomography showed a displaced diastatic fracture through right anterior atlantal synchondrosis. There are only 12 cases of paediatric C1 fractures reported in the world literature. The importance of considering this diagnosis in the appropriate clinical setting, and the normal variants in the paediatric atlas that can cause diagnostic dilemma to the interpreting radiologist, are discussed in this case report.

    The ocular and systemic characteristics of 160 patients with anterior uveitis and seronegative juvenile rheumatoid arthritis are reviewed. Chronic uveitis occurred in 131 patients, 76% of whom were girls. Both eyes were involved in 70% of the cases. Band keratopathy occurred in 41% of the eyes, cataract in 42%, and secondary glaucoma in 19%. Only 11 patients had uveitis before the onset of arthritis. Notable correlations included a pauciarticular onset of arthritis in 95% of the patients, and positive tests for antinuclear antibody in 82%. Of 29 patients with acute anterior uveitis, 27 were boys. The inflammation responded well to therapy, and serious complications did not occur. At follow-up 21 patients had typical ankylosing spondylitis, and five had sacroiliitis. The incidence of positive results of tests for HLA-B27 antigen was 94%.

Visual outcomes were also better in Appamide Plus group. T cell-mediated immunity study revealed initial CD3+ cell and T cell subpopulation deficiency. Relative and absolute references of T cells and their subpopulations tended to decrease even when uveitis signs reduced. Conclusions. T cell-mediated immunity depression is probably due to pharmacotherapy. Appamide Plus eye drops are highly effective for therapeutic mydriasis and pupillary massage in the course of anterior uveitis treatment to prevent synechiae formation in enlarged or small pupil.

Esta comparación se lleva a cabo dentro del marco general del proceso de modelado científico. Los autores concluyen que la principal diferencia entre las dos metodologías se encuentra en el proceso de abstracción que cada una de ellas realiza para construir el modelo formal a partir del sistema complejo observado. Esta diferencia inicial se extiende a las restantes etapas del proceso de modelado científico. Finalmente, se indican los principales factores y las propiedades generales de un sistema complejo que hacen que una u otra técnica sea más relevante, aunque los autores destacan que, en la mayoría de los casos, modelizar un mismo sistema mediante las dos técnicas es la solución idónea.

    Full Text Available O objetivo deste trabalho foi avaliar o efeito da cinetina e do cálcio sobre as características fisiológicas e produtivas de plantas de soja submetidas a estresses por deficit hídrico e sombreamento na fase de florescimento. Utilizou-se o delineamento de blocos ao acaso, em arranjo de parcelas subdivididas com quatro repetições. Plantas de soja cultivadas em vasos de 38 dm³ foram submetidas à aplicação de cálcio e cinetina, de forma isolada e combinada, no início do florescimento e, em seguida, submetidas a estresse por deficit hídrico e por sombreamento por 12 dias. Após o período de estresse, as plantas foram conduzidas até a maturação com suprimento adequado de água e radiação. A aplicação de cálcio e cinetina promoveu a manutenção do conteúdo relativo de água nas plantas, após quatro dias de deficit hídrico. O extravasamento de eletrólitos celulares, medido ao final do período de estresse, foi menor em plantas tratadas com cálcio e cinetina. A assimilação de CO2 foi reduzida pela imposição do estresse, principalmente do deficit hídrico, e a produção de grãos nos dois ambientes foi reduzida na mesma intensidade.

    MRI of a 62-year-old female presenting with ankle pain demonstrated an accessory muscle within the anterior compartment of the lower leg. The muscle originated from the fibula and anterior crural septum. The tendon passed anterior to the lateral malleolus and inserted at the critical angle of Gissane on the calcaneus. This muscle was initially described in the anatomic literature by Lambert and Atsas in 2010. To our knowledge, this is the first time the MRI appearances of this muscle has been described in the radiological literature. Awareness of the fibulocalcaneal muscle is important as it may represent a cause of ankle pain. In addition, the tendon could potentially be harvested for use in reconstructive procedures. (orig.)

En los últimos años hemos desarrollado una metodología sensible y reproducible utilizando la línea celular RTG-2, derivada de trucha arco iris (Oncorhynchus mykiss. Sin embargo, es preciso comprobar la capacidad predictiva de este ensayo mediante estudios in vivo. La línea celular RTG-2, como se ha evidenciado en trabajos anteriores, presenta una gran similitud genética con la especie de la que procede. Por ello, en este trabajo, se ha llevado a cabo una exposición subletal a benzo(apireno mediante inyección intraperitoneal de 69 μg/g de p.c. en alevines de trucha arco iris, valorando la aparición de mutaciones mediante la comparación del patrón de bandas obtenido a partir del ADN de células de sangre periférica, a diferentes tiempos (1 - 3 meses. Debido a que la presencia de bandas polimórficas dificulta el análisis entre los grupos de individuos tratados y no tratados, las comparaciones se realizaron en un mismo individuo antes y después del tratamiento. Los análisis cualitativos y cuantitativos mostraron tanto la aparición de nuevas bandas, como alteraciones en su intensidad confirmando, de esta manera, los resultados que previamente habíamos obtenido in vitro tras exposiciones a este mismo genotóxico

Five of these patients developed TASS postoperatively.Results: Patients had blurred-vision complaints on the first day after the operation, but no pain. They had different degrees of diffuse corneal edema, anterior-chamber reaction, fibrin, hypopyon, iris atrophies, and dilated pupils. Their vision decreased significantly, and their intraocular pressures increased. Both anti-inflammatory and antiglaucomatous therapies were commenced. Corneal edema and inflammation resolved in three cases; however, penetrating keratoplasty was needed for two cases and additional trabeculectomy was needed for one case. Although full investigations were undertaken at all steps, we could not find the causative agent.Conclusion: TASS is a preventable complication of anterior-segment surgery. Recognition of TASS, differentiating it from endophthalmitis, and starting treatment immediately is important. Controlling all steps in surgery, cleaning and sterilization of the instruments, and training nurses and other operation teams will help us in the prevention of TASS.

    Full Text Available Introduction. Infections after anterior cruciate ligament reconstructions are rare, but, on the other hand, they are difficult to be treated. The aim of this study was to analyze causes of infections, risk factors, diagnostics, and possibilities of their prevention. Material and Methods. Seventeen deep infections (1.2% were found in 1425 patients who had undergone anterior cruciate ligament reconstructions. Fifteen patients were males and two were females. Out of 475 professional athletes nine (1.9% had this postoperative complication. Eleven patients with septic arthritis were allergic to penicillin. Three of them had immunosuppressive diseases. Results. Staphylococcus aureus was isolated in eleven cases (65%, other Staphylococcus and Streptococcus groups were found in four and three patients, respectively; while one patient had infection although the punctate was negative. Out of 965 patients with the patellar tendon grafts, ten (1.03% had this complication, while the incidence was 1.52% (7/460 in those with the hamstring grafts. Fifteen infections were acute with obvious symptoms within 14 days after surgery. Severe pain, limited range of motion, swelling of the knee joint and fever were the most common symptoms, while rubor and pus developed rarely. The infection was three times more frequent in the patients who had undergone surgery lasting more than 1.5 hour. Discussion and Conclusion. The following population groups are at risk of developing septic arthritis after anterior cruciate ligament reconstructions: professional athletes, those who are allergic to penicillin, and those with immunosuppressive diseases. Staphyllococus aureus is the most common cause of infection. The patients with the hamstring autografts have a higher risk than those with the patellar tendon grafts. Preventive measures that should be performed include aseptic conditions in operative rooms, irrigation of the graft before its placement into the bone tunnels

Of primary interest is the contribution of the cingulate cortex in processing the affective component of pain. The purpose of this review is to summarize recent data obtained using novel behavioral paradigms in animals based on measuring escape and/or avoidance of a noxious stimulus. These paradigms have successfully been used to study the nature of the neuroanatomical and neurochemical contributions of the anterior cingulate cortex to higher order pain processing in rodents.

    Full Text Available Successful anterior cruciate ligament (ACL reconstruction with tendon graft requires extensive tendon-to-bone healing in the bone tunnels and progressive graft ligamentization for biological, structural, and functional recovery of the ACL. Improvement in graft-to-bone healing is crucial for facilitating early, aggressive rehabilitation after surgery to ensure an early return to pre-injury activity levels. The use of various biomaterials for enhancing the healing of tendon grafts in bone tunnels has been developed. With the biological enhancement of tendon-to-bone healing, biological fixation of the tendon graft in the tunnel can be achieved in ACL reconstruction.

    The purpose of the study was to describe the findings seen on anterior segment spectral domain optical coherence tomography (SD-OCT) in patients with anterior scleritis and determine the feasibility of using SD-OCT to image and grade the degree of scleral inflammation and monitor response to treatment. All patients underwent slit lamp examination by a uveitis specialist, and the degree of scleral inflammation was recorded. Spectral domain OCT imaging was then performed of the conjunctiva and scleral tissue using a standardized acquisition protocol. The scans were graded and compared to clinical findings. Twenty-eight patients with anterior scleritis and ten patients without ocular disease were included in the study. Seventeen of the scleritis patients were followed longitudinally. Common findings on SD-OCT in patients with active scleritis included changes in hyporeflectivity within the sclera, nodules, and visible vessels within the sclera. There was significant variation in findings on SD-OCT within each clinical grade of active scleritis. These changes on SD-OCT improved with treatment and clinical improvement. SD-OCT imaging provided various objective measures that could be used in the future to grade inflammatory activity in patients with anterior scleritis. Longitudinal imaging of patients with active scleritis demonstrated that SD-OCT may have great utility in monitoring response to treatment.

    2017-01-01

    Full Text Available A 31-year-old healthy male underwent deep anterior lamellar keratoplasty with big-bubble technique for treatment of keratoconus in his right eye. One week after surgery, he presented with detachment of the endothelium-Descemet complex with formation of a double anterior chamber, despite the apparent absence of an intraoperative Descemet membrane rupture. A subsequent intervention with the intent to relocate the corneal graft button was not effective, because the detachment appeared again one day later. The authors hypothesized that, at the time of the stromal dissection with big bubble technique, a small amount of air penetrated into the anterior chamber, creating a false pathway through the trabecular meshwork. The aqueous humor then penetrated the graft flowing through the false pathway, causing the endothelium-Descemet detachment. The persistence of that pathway, even after the intervention of graft repositioning, caused the failure of the latter procedure and persistence of the double chamber. We decided to wait and observe. The double anterior chamber spontaneously resolved in approximately three months.

Panteleimon,” Piraeus, 3Department of Medical Psychology, Medical School of Ioannina, University of Ioannina, Ioannina, Greece Abstract: Anterior cutaneous nerve entrapment syndrome (ACNES is a commonly underdiagnosed and undertreated chronic state of pain. This syndrome is characterized by the entrapment of the cutaneous branches of the lower thoracoabdominal intercostal nerves at the lateral border of the rectus abdominis muscle, which causes severe, often refractory, chronic pain. This narrative review aims to identify the possible therapeutic strategies for the management of the syndrome. Seventeen studies about ACNES therapy were reviewed; of them, 15 were case–control studies, case series, or case reports, and two were randomized controlled trials. The presently available management strategies for ACNES include trigger point injections (diagnostic and therapeutic, ultrasound-guided blocks, chemical neurolysis, and surgical ­neurectomy, in combination with systemic medication, as well as some emerging techniques, such as radiofrequency ablation and neuromodulation. An increased awareness of the syndrome and the use of specific diagnostic criteria for its recognition are required to facilitate an early and successful management. This review compiles the proposed ­management strategies for ACNES. Keywords: anterior cutaneous nerve entrapment syndrome, intercostal, neuralgia, management

    Anterior cervical fusion has become a standard of care for numerous pathologic conditions of the cervical spine. However, subsequent development of clinically significant disc disease at levels adjacent to fused discs is a serious long-term complication of this procedure. As more patients live longer after surgery, it is foreseeable that adjacent segment pathology (ASP) will develop in increasing numbers of patients. Also, ASP has been studied more intensively with the recent popularity of motion preservation technologies like total disc arthroplasty. The true nature and scope of ASP remains poorly understood. The etiology of ASP is most likely multifactorial. Various factors including altered biomechanical stresses, surgical disruption of soft tissue and the natural history of cervical disc disease contribute to the development of ASP. General factors associated with disc degeneration including gender, age, smoking and sports may play a role in the development of ASP. Postoperative sagittal alignment and type of surgery are also considered potential causes of ASP. Therefore, a spine surgeon must be particularly careful to avoid unnecessary disruption of the musculoligamentous structures, reduced risk of direct injury to the disc during dissection and maintain a safe margin between the plate edge and adjacent vertebrae during anterior cervical fusion.

    The purpose of this study was to assess the usefulness of MRI in the evaluation of autografts after anterior cruciate ligament reconstruction. The subjects were 110 patients with anterior cruciate ligament reconstruction using patellar tendon autografts who underwent clinical examination, MRI, and arthroscopy of the knee. T1- and T2-weighted MR images were obtained in sagittal plane. Clinical findings were categorized into three groups: normal, borderline, and abnormal. The MRI appearances of the autografts were categorized into three types: straight continuous band (type I), interrupted band (type II) and generalized increased intensity band (type III). The clinical findings and MRI findings were compared with arthroscopic findings. Ninety-six percent of the type I showed no autograft tear on arthroscopy. In comparison with the clinical findings, MRI was found to be well correlated with arthroscopic findings. In conclusion, if the clinical findings are normal, patients are to be followed-up without MRI and arthroscopy. However, if clinical findings are either borderline or abnormal, MRI should be performed prior to arthroscopy. (author)

El modo de participación en la elección y la manera como éstas se convierten en cargos públicos, requiere del dise- ño de instituciones que sistematicen dicha participación. La república de tipo presidencial, es una modalidad del gobierno electivo y popular, cuyo titular es el jefe del ejecutivo, electo por el pueblo o sus representantes, en donde el ejercicio del poder es limitado y mantiene un régimen de responsabilidades políticas. El diseño institucional que le corresponde a esta forma de gobierno es la parcelación del poder pú- blico en tres: poder ejecutivo, poder legislativo y poder judicial. Las ventajas políticas de este esquema es que la división de poderes, neutraliza el riesgo de caer en el autoritarismo, al impedir que el poder se concentre. La división de poderes es un dispositivo de restricción de facultades de los órganos estatales, por lo que no existe superioridad jerárquica entre los poderes, al contrario, cada órgano tiene bien delimitadas sus funciones y atribuciones, las que están reguladas por un marco jurídico común llamado Constitución. Y la división de poderes contribuye a mantener el equilibrio entre estos, mediante el llamado sistema de “pesos y contrapesos”. El presente trabajo se centra en el estudio de la Cámara de Diputados, considerada como una de las parcelas en las que está divida la autoridad del Estado, cuyo objetivo es la validación de los modelos teóricos en la tipificación del Congreso y la comprensión de las variables internas y externas que influyen en el comportamiento legislativo.

Observou-se que, independentemente da concentração testada, o floroglucinol não promoveu a indução do enraizamento de estacas lenhosas. A cultivar MC apresentou melhor percentagem de enraizamento, número de raízes e percentagem de estacas brotadas.The quince belongs from the family Rosaceae. Now, it has been used as rootstock tree door-graft because it induce dwarf plants. The floroglucinol is a phenolic compost, which effects is by increased the auxine and that tends to induce and to increase hardwoody cuttings. The present work was carried out in a greenhouse with intermittent mist writh the objective to determine the best quince cultivars in relation to its capacity of rooting hardwoody cuttings, and the best floroglucinol concentration for the root induction. The cultivars Pineapple, Meliform, Prolonged, Radaelli, Portugal, Inta and MC were used. They were submitted to three treatments of different floroglucinol concentrations (zero, 1500 and 3000 mg.L-1. The cuttings with 12 cm and ½ leaf in the superior part were conditioned

Los resultados mostraron cómo el CA (de origen A o B es capaz de remover boro a valores por debajo de 0,75 mg/L. Sin embargo, en una etapa inicial (primera quincena los efluentes a este medio filtrante, presentaron un valor de CE mayor a 2,5 dS/m, y de pH mayor a 8,4, lo que seguramente traerá problemas para su aplicación en riego de cultivos. Por su parte, la arena, al ser de la región, presenta problemas de lixiviación de elementos, como el arsénico y el sodio, por lo que no debería utilizarse como material filtrante. Por el contrario, el único medio evaluado que tiene potencial de ser aplicado en la reducción de la salinidad es la zeolita. Este material filtrante, sin mezcla con otro, fue capaz de reducir hasta un 20 % el valor de la CE sin tener un efecto negativo en ninguno de los otros parámetros evaluados en este estudio, y además, sin mostrar un estado de saturación durante el tiempo de operación evaluado. En el caso de las columnas que utilizaron mezclas de materiales, no existe un efecto sinérgico para la eliminación de los parámetros de calidad del agua evaluados.

    Summary: Orbscan- Ⅱ anterior system was used for early diagnosis of keratoconus. 48 Eyes of 24patients with suspicious keratoconus were examined by Orbscan-Ⅱ anterior system from Dec.1999 to Dec. 2000 and followed up. The values of Diff and anterior chamber depth (ACD) wererecorded. Results indicated that values of Diff and ACD were increased in 4 eyes of 2 patients withkeratoconus trend during follow-up. Taking advantage of Orbscan- Ⅱ anterior system to observethe values of Diff and ACD can early diagnose the sub-clinical keratoconus. The values of Diff andACD can sensitively report the progression of keratoconus.

    2005-06-01

    Full Text Available Abstract Background The ocular anterior segment is critical for focusing incoming light onto the neural retina and for regulating intraocular pressure. It is comprised of the cornea, lens, iris, ciliary body, and highly specialized tissue at the iridocorneal angle. During development, cells from diverse embryonic lineages interact to form the anterior segment. Abnormal migration, proliferation, differentiation, or survival of these cells contribute to diseases of the anterior segment such as corneal dystrophy, lens cataract, and glaucoma. Zebrafish represent a powerful model organism for investigating the genetics and cell biology of development and disease. To lay the foundation for genetic studies of anterior segment development, we have described the morphogenesis of this structure in zebrafish. Results As in other vertebrates, the zebrafish anterior segment derives from diverse origins including surface ectoderm, periocular mesenchyme, and neuroepithelium. Similarly, the relative timing of tissue differentiation in the anterior segment is also conserved with other vertebrates. However, several morphogenic features of the zebrafish anterior segment differ with those of higher vertebrates. These include lens delamination as opposed to invagination, lack of iris muscles and ciliary folds, and altered organization in the iridocorneal angle. In addition, substantial dorsal-ventral differences exist within the zebrafish anterior segment. Conclusion Cumulatively, our anatomical findings provide a reference point to utilize zebrafish for genetic studies into the mechanisms of development and maintenance of the anterior segment.

O diagnóstico foi firmado pelo achado do bacilo de Koch no liqüido cefalorraqueano e pela inoculação em cobaio. O tratamento foi iniciado no 8.° dia depois de se declararem os sinais da meningite e durou 71 dias, tendo o pacente recebido um total de 44.600.000 U. de Estreptomicina, sendo 42.650.000 U. por via intramuscular e 1.950.000 U. por via intratecal, em 41 punções lombares e suboccipitais. Durante o tratamento, em sua fase final, foi associado o Promin. Os autores acreditam que os resultados obtidos se devem, entretanto, à Estreptomicina, com a qual, desde o início do tratamento, se modificou de maneira nítida a marcha da moléstia. Após 40 dias de terminado o tratamento, o paciente se apresentava como uma criança normal, sem apresentar seqüela neurológica alguma. Repetidos exames do líqüido cefalorraqueano mostraram progressiva diminuição das alterações, restando, no final, apenas hipercitose linfocitária de 72 células por mm3, aumento da taxa de proteínas e fino retículo fibrinoso. Os autores, apesar dos brilhantes resultados obtidos, não afirmam a cura completa, dado que o período de observação ainda é julgado insuficiente para uma apreciação definitiva.

    Full Text Available ABSTRACT We read with interest the article by Surekha et al. regarding the retained stone piece in anterior chamber. Similar to the results of previous studies, the authors found that delayed intraocular foreign body (IOFB management can result in good visual outcome without an apparent increased risk of endophthalmitis or other deleterious side effects. However, the authors failed to explain the exact reason for the diminution of vision in patients left eye. It is unclear what the uncorrected visual acuity was and what kind of correction was used, more precisely type and amount of cylinder, given the presence of the corneal opacity. Since the size of the IOFB is approximately 4x4x1mm, significant irido-corneal angle changes resulting in intraocular pressure raise and optic nerve head damage can be expected. Traumatic glaucoma following open globe injury can occur in 2.7 to 19% of cases, with several risk factors associated with glaucoma development (advanced age, poor visual acuity at presentation,perforating rather than penetrating ocular injury,lens injury, presence of vitreous hemorrhage and presence of an IOFB. Earlier reportsof latetraumaticoptic neuropathy onset, even after several years, indicate that this possibility cannot be completely ruled out too. Therefore, repeated intraocular pressure measurements, gonioscopy, pupillary reaction assessment, together with through posterior segment examination including visual field and optical coherence tomography examinations can be useful in determining the possible optic nerve damage as one of the possible reasons for visual acuity reduction. The authors did not suggest any operative treatment at this time. However, it should bear in mind that the inert anterior chamber IOFB could be a risk factor for non-infectious endophthalmitis development even after many years. Also, long term retained anterior chamber foreign body leads to permanent endothelial cell loss and can even result in a corneal

    The lack of reported complications related to lower extremity peripheral nerve blocks (PNBs) may be related to the relatively infrequent application of these techniques and to the fact that most such events go unpublished. Our current understanding of the factors that lead to neurologic complications after PNBs is limited. This is partly the result of our inability to conduct meaningful retrospective studies because of a lack of standard and objective monitoring and documentation procedures for PNBs. We report a case of permanent injury to the sciatic nerve after sciatic nerve block through the anterior approach and discuss mechanisms that may have led to the injury. Intraneural injection and nerve injury can occur in the absence of pain on injection and it may be heralded by high injection pressure (resistance).

    The association between anterior uveitis (AU) and diabetes mellitus (DM) has always been known. The purpose of this study was to estimate the incidence of this association and to consider a possible role of the cell-mediated immune system. During the years 1989-1992, 196 diabetics (66 patients affected by type I DM and 130 by type II DM) were studied. The study of the lymphocytic subsets and the measurement of the circulating immunocomplexes and autoantibodies (ANA, AMA, ADNA, ASMA, APCA) were carried out, and the results were compared with those of a control group. The results underline the correlation between AU and type I DM. Many immunological reactions could play a crucial role: the high levels of CD8 subsets found could be an expression of the unstable lymphocytic equilibrium.

    Full Text Available Background: Although microscopic anterior cervical discectomy with or without fusion are common surgical procedures for treatment of cervical herniated discs, loss of disc height, pseudarthrosis, and adjacent disc degeneration are some of the problems associated with it. This study is aimed to evaluate results of endoscopic microforaminotomy in cervical disc diseases. Materials and Methods: A prospective study of 50 patients of mono segmental soft or hard disc causing myeloradiculopathy was undertaken. A visual analogue scale (VAS for neck and arm pain and functional outcomes using the Nurick grading system were assessed. There were 28, 12, 8, and 2 patients at C5-6, C6-7, C4-5, and C3-4 levels disc diseases, respectively. Patients with two or more level disc, instabilities, disc extending more than half vertebral body height, and previous operation at the same segment were excluded. Results: Age ranged from 21 to 67 years. Average postoperative reduction in disc height, operating time, and blood loss was 1.1 mm, 110 minutes, and 30 ml, respectively. Average pre-operative VAS score for arm pain and Nurick grading was 7.6 and 2.7, which improved to 1.9 and 0.82, respectively. All patients improved; 1, 2, 3 grade improvement was seen in 10, 27, and 10 patients, respectively. There was no significant complication or any mortality. Conclusion: Although longer follow up of large number of patients is required, endoscopic microforaminotomy is a safe and an effective alternative to microscopic anterior discectomy with or without fusion.

    Objectives: The purpose of this study was to determine the clinical outcomes following revision anterior shoulder stabilization performed either via all-arthroscopic soft tissue repair or via Latarjet coracoid transfer. Methods: A retrospective review of prospectively collected data on 91 shoulders undergoing revision anterior shoulder stabilization was performed. All patients underwent prior soft tissue stabilization; those with prior open bone grafting procedures were excluded. For patients with 25% glenoid bone loss, Latarjet was performed (n=28). Patients were queried regarding recurrent instability (subluxation or dislocation). Clinical outcomes were evaluated using validated patient reported outcome questionnaires including the American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test (SST), visual analog scale (VAS) for pain, and Western Ontario Shoulder Instability Index (WOSI). Results: A total of 63 shoulders in 62 patients (46 males, 16 females) with an average age of 23.2 ± 6.9 years were included in the revision arthroscopy group. At an average follow-up of 46.9 ± 16.8 months (range, 15 to 78), the mean WOSI score was 80.1 (range, 15.0 to 100), and there were significant improvements (pLatarjet group. Thirteen (46%) had more than one previous stabilization attempt. ), the average WOSI score was 71.9, and there were significant improvements (pLatarjet. Conclusion: Both arthroscopic revision stabilization and Latarjet coracoid transfer result in satisfactory outcomes in patients who have failed previous arthroscopic capsulolabral repair. Recurrent instability rates were higher in the all-arthroscopic group (19% versus 7%). Longer-term studies are required to determine whether similar results are maintained over time, and to provide guidance on focused clinical indications for this challenging patient population.

  2. Etiological aspects of anterior open bite

    Stojanović Ljiljana

    2007-01-01

    Full Text Available Introduction. Open bite is a multifactorial phenomenon and no single factor can account for open-bite. Etiology plays an important role in diagnosis. Heredity, unfavorable growth patterns, incorrect jaw postoure, are the characteristics of skeletal open bite. Digit sucking. Depending on where the thumb is placed, a number of different types of dental problems can develop. Malocclusions of the late mixed or permanent dentitions, caused by thumb sucking are not self corrected and orthodontic treatment is necessary for their correction. Lymphatic tissue. In order to produce oral respiration, the mandible is postured inferiorly with the tongue protruded and resting against the oral floor. This postural alteration induces dental and skeletal modifications similar to those caused by thumb sucking. This may cause excessive eruption of the posterior teeth, leading to an increase in the vertical dimension of the face and result in development of anterior open bite. Tongue thrust. Tongue habits cause an anterior open bite or they develop secondarily to thumb sucking. In skeletal open bite the tongue habit acts as a secondary factor which helps to maintain or exacerbate the condition. Many orthodontists have had a discouraging experience of completing dental treatment, with what appeared to be good results, only to discover that the case had relapsed because the patient had a tongue thrust swallowing pattern. Conclusion. Dentoalveolar or habitual open bite is caused by habits, which influence the growth and development of dentoalveolar processes and contribute to occlusal disharmonies. Prior to eruption of adult dentition, open bite related to oral habits is usually not a concern as when the habits stop, because the erupting dentition tends to improve spontaneously. Treatment is usually not necessary until permanent teeth erupt (~6 years old. .

    Video-assisted thoracoscopic surgery (VATS) has been widely used, but surgical resections of superior sulcus tumours remain challenging because of their anatomical location. For such cases, less-invasive procedures, such as the anterior transcervical-thoracic and transmanubrial approaches, have been widely performed because of their excellent visualization of the subclavian vessels. Recently, a combined operative technique with an anterior surgical approach and VATS for anterior superior sulcus tumours has been introduced. Herein, we report three cases of anterior superior sulcus tumours successfully resected by surgical approaches combined with a VATS-based lobectomy. In all cases, operability was confirmed by VATS, and upper lobectomies with hilar and mediastinal lymph node dissections were performed. Subsequently, dissections of the anterior inlet of the tumours were performed using the transmanubrial approach in two patients and the anterior trans-cervical-thoracic approach in one patient. Both approaches provided excellent access to the anterior inlet of the tumour and exposure of the subclavian vessels, resulting in radical resection of the tumour with concomitant resection of the surrounding anatomical structures, including the chest wall and vessels. In conclusion, VATS lobectomy combined with the anterior surgical approach might be an excellent procedure for the resection of anterior superior sulcus tumours.

    Purpose: To observe the effect of preserving anterior ciliary vessels (ACVs) on anteriorsegments of rabbit eyes undergoing tenotomy of extraocular muscles.Methods: Thirty-two adult New Zealand white rabbits were divided into four groups.Same procedures were done in both eyes in each group except that left eyes underwentpreservation of ACVs. In the first group medial and lateral recti, in the second group,superior and inferior recti, in the third group, medial, lateral and superior or inferior rectiand in the fourth group, all four recti, underwent tenotomy. Slit-lamp examination,intraocular pressure (IOP) measurement, total protein and lactic acid quantification inaqueous humor were done in all eyes pre- and post-operatively. By four weeks afteroperation, the eyes were enucleated for histological examination and electron microscopy.All data were analyzed using SPSS version 10.Results: In the left eyes of both group 1 and group 2, no inflammatory response wasobserved. In the left eyes of group 3 and 4, we observed mild inflammatory response withslit-lamp examination, which disappeared in one wk. However, we did not findsignificant changes in IOP, total protein and lactic acid of aqueous humor, histology andelectron microscopic examination in these groups. In the right eyes in group 2, 3 and 4,we observed moderate to severe inflammatory changes, a few even developed anteriorsegment ischemia, appeared as decreased IOP, increased total protein and lactic acid inaqueous humor, along with pathological and electron-microscopic changes.Conclusion: Simultaneous tenotomy of three or four recti or two vertical recti on one eyemay decrease anterior segment blood flow even lead to ischemia. ACVs preservation mayprotect the blood circulation in anterior segment. Our study suggests that ACVspreservation in strabismus surgeries especially those involving multi-recti tenotomies mayprevent potential anterior segment ischemia.

    Anterior cruciate ligament (ACL) injury in the skeletally immature individual is being recognized with increasing frequency. Nonoperative treatment of ACL injuries in skeletally immature patients have not been favorable. Surgical treatment options for complete ACL tears include primary ligament repair, extraarticular tenodesis, transphyseal reconstruction, partial transphyseal reconstruction, and physeal-sparing reconstruction. The advantage of transphyseal reconstruction is placement of the graft tissue in an isometric position, which provides better results, according to the literature. The potential disadvantage is angular or limb-length discrepancy caused by physeal violation. Controversy exists in allograft selection about whether bone or soft tissue passes into physes. The use of standard tunnels provides reliable results, but carries the risk of iatrogenic growth disturbance from physeal injury.This article presents 4 cases of transphyseal ACL reconstruction using anterior tibialis allograft in skeletally immature patients that had satisfactory functional outcomes with no growth disturbances. This is the first report of transphyseal ACL reconstruction using anterior tibialis allograft in skeletally immature patients in the English-speaking literature. All patients underwent transphyseal ACL reconstruction using anterior tibialis tendon allograft. None of the patients had angular deformities. No early physeal arrest was measured between the preoperative and postoperative radiographs. At last follow-up, the results of the Lachman test were normal for 3 patients and nearly normal for 1 patient. All patients demonstrated full range of knee motion (comparing the reconstructed knee to the contralateral knee). The results of the pivot-shift test were normal for 3 patients and nearly normal for 1 patient. No patients reported giving way.

    Zebrafish with defective Nodal signaling have a phenotype analogous to the fatal human birth defect anencephaly, which is caused by an open anterior neural tube. Previous work in our laboratory found that anterior open neural tube phenotypes in Nodal signaling mutants were caused by lack of mesendodermal/mesodermal tissues. Defects in these mutants are already apparent at neural plate stage, before the neuroepithelium starts to fold into a tube. Consistent with this, we found that the requirement for Nodal signaling maps to mid-late blastula stages. This timing correlates with the timing of prechordal plate mesendoderm and anterior mesoderm induction, suggesting these tissues act to promote neurulation. To further identify tissues important for neurulation, we took advantage of the variable phenotypes in Nodal signaling-deficient sqt mutant and Lefty1-overexpressing embryos. Statistical analysis indicated a strong, positive correlation between a closed neural tube and presence of several mesendoderm/mesoderm-derived tissues (hatching glands, cephalic paraxial mesoderm, notochord, and head muscles). However, the neural tube was closed in a subset of embryos that lacked any one of these tissues. This suggests that several types of Nodal-induced mesendodermal/mesodermal precursors are competent to promote neurulation.

    Full Text Available The aim of this study was to reveal the clinical features of anterior urethral recurrence in patients with superficial bladder cancer, and to determine the appropriate treatment. Three hundred and three patients with superficial bladder cancer, who were newly diagnosed and initially treated conservatively in our hospital between 1965 and 1990, were followed for at least 5 years and their clinical outcomes were analyzed. Clinical factors, including anterior urethral recurrence, were evaluated statistically regarding tumor progression. Eight patients (2.6% had anterior urethral recurrence following superficial bladder cancer. Twenty-four patients (7.9% had tumor progression and 149 (49.2% had tumor recurrence. In a multivariate analysis using a logistic model, anterior urethral recurrence was the most important factor, followed by histological grade. Four of 5 patients who were treated for anterior urethral recurrent tumors by transurethral resection showed progression and died of the cancer within one year. Two of the remaining three patients who underwent radical cysto-urethrectomy at the time of anterior urethral recurrence survived. Anterior urethral recurrence following superficial bladder cancer is a predictor for rapid subsequent malignant progression. Once there is anterior urethral recurrence, radical intensive therapy, including radical cysto-urethrectomy, should be carried out immediately.

    We report a rare case of unilateral agenesis of the internal carotid artery in association with congenital anterior hypopituitarism. The collateral circulation is supplied by a transsellar intercavernous anastomotic vessel connecting the internal carotid arteries. These abnormalities are well depicted on MRI and MRA. The agenesis of the internal carotid artery may explain the pathogenesis of some of congenital anterior hypopituitarism. (orig.)

  1. Anterior endoderm and head induction in early vertebrate embryos.

    de Souza, F S; Niehrs, C

    2000-05-01

    Early work on the formation of the vertebrate body axis indicated the existence of separate head- and trunk-inducing regions in Spemann's organizer of the amphibian gastrula. In mammals some head-organizing activity may be located in anterior visceral (extraembryonic) endoderm (AVE). By analogy, the equivalent structure in the Xenopus laevis gastrula, the anterior endoderm, has been proposed to be the amphibian head organizer. Here we review recent data that challenge this notion and indicate that the involvement of AVE in head induction seems to be an exclusively mammalian characteristic. In X. laevis and chick, it is the prechordal endomesoderm that is the dominant source of head-inducing signals during early gastrulation. Furthermore, head induction in mammals needs a combination of signals from anterior primitive endoderm, prechordal plate, and anterior ectoderm. Thus, despite the homology of vertebrate anterior primitive endoderm, a role in head induction seems not to be conserved.

    The purpose of this study was to analyse the occurrence of variants of anomalous insertions of the anterior horn of the medial meniscus in human knee joints. The study was carried out on 78 human lower limbs of both sexes (42 males and 36 females). Out of 78 knee joints, 10 knee joints (12.82%) presented atypical attachments of the anterior horn of the medial meniscus. In 9 cases we found that the anterior horn of the medial meniscus was attached to the transverse ligament of the knee and in 1 case it was attached to the coronary ligament. In the remaining cases the anterior horn of the medial meniscus was attached to the anterior intercondylar area of the tibia.

    Anterior chamber volume (ACV) is very important for an oculist to make rational pathological diagnosis as to patients who have some optic diseases such as glaucoma and etc., yet it is always difficult to be measured accurately. In this paper, a method is devised to measure anterior chamber volumes based on JPEG-formatted image files that have been transformed from medical images using the anterior-chamber optical coherence tomographer (AC-OCT) and corresponding image-processing software. The corresponding algorithms for image analysis and ACV calculation are implemented in VC++ and a series of anterior chamber images of typical patients are analyzed, while anterior chamber volumes are calculated and are verified that they are in accord with clinical observation. It shows that the measurement method is effective and feasible and it has potential to improve accuracy of ACV calculation. Meanwhile, some measures should be taken to simplify the handcraft preprocess working as to images.

OBJETIVO: Avaliar a evolução clínica tardia dos pacientes submetidos a implante de stents farmacológicos nas lesões ateroscleróticas da artéria descendente anterior e identificar, entre as características clínicas, angiográficas e do ultra-som intravascular, quais as que permitem predizer risco de eventos cardíacos. MÉTODOS: De maio de 2002 a agosto de 2005, foram tratados 205 pacientes com implante de 236 stents farmacológicos guiados pelo ultra-som intravascular. RESULTADOS: Com um acompanhamento médio de 711 dias, a taxa de trombose do stent foi de 0,48%, a mesma observada para infarto agudo do miocárdio ou cirurgia de revascularização. A taxa de revascularização da lesão tratada foi de 7,31% e a taxa global de eventos de 10,24%. Os indicadores de eventos, conforme análise multivariada, foram o implante de mais de um stent na mesma artéria, lesões concêntricas e área mínima intra-stent medida pelo ultra-som intravascular menor que 3,88 mm². CONCLUSÃO: Baseados nos dados obtidos, concluímos que a revascularização da artéria descendente anterior com implante de stents farmacológicos escolhidos e otimizados pelo ultra-som intravascular apresenta baixo índice de eventos tardios. O implante de dois stents farmacológicos para o tratamento das lesões longas foi o principal fator independente para a ocorrência de eventos tardios. A área luminal final maior que 3,88 mm² obtidos nos segmentos de pequenos diâmetros de referência é um indicador independente de evolução livre de eventos.FUNDAMENTO: La eficacia de los stents farmacológicos para reducir los índices de eventos cardiacos no es la misma para todos los subgrupos de lesiones o pacientes.

  6. Anterior commissure versus corpus callosum: A quantitative comparison across mammals.

    Science.gov (United States)

    Ashwell, Ken W S

    2016-04-01

    Mammals rely on two major pathways to transfer information between the two hemispheres of the brain: the anterior commissure and the corpus callosum. Metatheria and monotremes rely exclusively on the anterior commissure for interhemispheric transfer between the isocortices and olfactory allocortices of each side, whereas Eutheria use a combination of the anterior commissure and an additional pathway exclusive to Eutheria, the corpus callosum. Midline cross-sectional area of the anterior commissure and corpus callosum were measured in a range of mammals from all three infraclasses and plotted against brain volume to determine how midline anterior commissure area and its size relative to the corpus callosum vary with brain size and taxon. In Metatheria, the square root of anterior commissure area rises in almost direct proportion with the cube root of brain volume (i.e. the ratio of the two is relatively constant), whereas among Eutheria the ratio of the square root of anterior commissure area to the cube root of brain volume declines slightly with increasing brain size. The total of isocortical and olfactory allocortical commissure area rises more rapidly with increasing brain volume among Eutheria than among Metatheria. This means that the midline isocortical and olfactory allocortical commissural area of metatherians with large brains (about 70 ml) is only about 50% of that among eutherians with similarly sized brains. On the other hand, isocortical and olfactory allocortical commissural area is similar in Metatheria and Eutheria at brain volumes around 1 ml. Among the Eutheria, some groups make less use of the anterior commissure pathway than do others: soricomorphs, rodents and cetaceans have smaller anterior commissures for their brain size than do afrosoricids, erinaceomorphs and proboscideans. The findings suggest that use of the anterior commissural route for isocortical commissural connections may have placed limitations on interhemispheric transfer of

    Full Text Available Cataratas polares anteriores piramidais são opacidades cônicas que se projetam para a câmara anterior a partir da cápsula anterior do cristalino. Na grande maioria dos pacientes a opacidade permanece aderida e estável durante toda a vida. O objetivo deste trabalho é documentar uma manifestação incomum desse tipo de catarata: a deiscência espontânea das pirâmides para a câmara anterior causando descompensação endotelial e edema corneal bilateral. Relatamos o caso de uma paciente feminina, de 66 anos, branca, que apresentava edema corneal localizado inferiormente no olho direito associado à lesão nodular branco-esclerótica compatível com a pirâmide anterior da catarata polar. O olho esquerdo apresentava edema corneal difuso intenso e presença de uma catarata polar anterior com a região piramidal deslocada para a câmara anterior. Sabe-se que a pirâmide anterior pode permanecer inabsorvida na câmara anterior por longo período, pois é composta de tecido colágeno denso. Isto causa perda endotelial progressiva e edema corneal e deve ser considerada indicação de remoção cirúrgica da catarata polar anterior e de seu fragmento. Ressalta-se, também, a importância do bom senso no julgamento das cataratas polares anteriores, considerando-se tamanho da opacidade, simetria das opacidades e componente cortical associado, na tentativa de se evitar ambliopia.Pyramidal anterior polar cataracts are conical opacities that project into the anterior chamber from the anterior capsule of the lens.

    Waggoner, William F

    2015-01-01

    The purpose of this paper was to review the current literature associated with the techniques and materials for the restoration of primary anterior teeth and make clinical recommendations based upon the available literature. A variety of esthetic restorative materials are available to utilize for restoring primary incisors. Awareness of the specific strengths, weakness, and properties of each material can enhance the clinician's ability to make the best choice of selection for each individual situation. Intracoronal restorations of primary teeth may utilize resin composites, glass ionomer cements, resin-modified ionomers, or polyacid-modified resins. Full coronal restoration of primary incisors may be indicated for a number of reasons. Crowns available for restoration of primary incisors include those that are directly bonded onto the tooth, which generally are a resin material, and crowns that are luted onto the tooth and are either some type of stainless steel or zirconia crown. There is insufficient controlled, clinical data to suggest that one type of restoration is superior to another. Operator preferences, esthetic demands by parents, the child's behavior, the amount of tooth structure remaining, and moisture and hemorrhage control are all variables that affect the decision and ultimate outcome of whatever restorative solution is chosen.

    2017-01-01

    Anterior cutaneous nerve entrapment syndrome (ACNES) is a commonly underdiagnosed and undertreated chronic state of pain. This syndrome is characterized by the entrapment of the cutaneous branches of the lower thoracoabdominal intercostal nerves at the lateral border of the rectus abdominis muscle, which causes severe, often refractory, chronic pain. This narrative review aims to identify the possible therapeutic strategies for the management of the syndrome. Seventeen studies about ACNES therapy were reviewed; of them, 15 were case–control studies, case series, or case reports, and two were randomized controlled trials. The presently available management strategies for ACNES include trigger point injections (diagnostic and therapeutic), ultrasound-guided blocks, chemical neurolysis, and surgical neurectomy, in combination with systemic medication, as well as some emerging techniques, such as radiofrequency ablation and neuromodulation. An increased awareness of the syndrome and the use of specific diagnostic criteria for its recognition are required to facilitate an early and successful management. This review compiles the proposed management strategies for ACNES. PMID:28144159

    Smékal, D; Kalina, R; Urban, J

    2006-12-01

    Rehabilitation is an important part of therapy in patients who have had arthroscopic anterior cruciate ligament reconstruction. A well-designed rehabilitation program avoids potential graft damage and speeds up patients' return to their full function level. The course of rehabilitation depends on the type of surgery, mode of fixation and possible co-existing injury to the knee's soft tissues. The rehabilitation program presented here is based on the present-day knowledge of neurophysiological and biomechanical principles and is divided into five phases. In the pre-operative phase (I), the main objective is to prepare patients for surgery in terms of maximum muscle strength and range of motion. It also includes providing full information on the procedure. In the early post-operative phase (II) we are concerned with pain alleviation and reduction of knee edema. After suture removal we begin with soft techniques for the patella and post-operative physical therapy to reduce scarring. In the next post-operative phase (III) patients are able to walk with their full weight on the extremity operated on, and we continue doing exercises that improve flexor/extensor co-contraction. In this phase we also begin with exercises improving the patient's proprioceptive and sensorimotor functions. In the late post-operative phase (IV) we go on with exercises promoting proprioception of both lower extremities with the aim of increasing muscle control of the knee joints. In the convalescent phase (V) patients gradually return to their sports activities.

    Full Text Available Objective: To evaluate the surgical technique with bifrontal interhemispheric approach for total removal of tumor in olfactory groove meningioma (OGM. Methods: This study described a case of a 38-year-old woman with bilateral blindness, anosmia, and behaviour changes. Imaging studies show a tumor mass in midfrontal base. Surgery using a bifrontal interhemispheric approach was performed and total removal was achieved and postoperative computed tomography (CT scan was performed to confirm the result. Histopathological findings established a diagnosis of meningioma. Results: A coronal skin incision behind the hairline was utilized. The scalp was elevated, taking care to reserve the vascularized pericranium medial to the linea temporalis of each side, and preserving the 2 supraorbital nerves. Eight burr holes were used, with the two initial holes made on each side of the orbitotemporal region, and the other four holes at the midline. A bifrontal craniotomy was performed. The tumor was first detached from its attachment with bipolar cautery and debulked. During this step, the main tumor feeder arteries from the anterior and posterior ethmoidal artery were interrupted, and the tumor devascularized. Total tumor removal through surgical intervention was achieved and confirmed by head CT-scan postoperatively. Conclusions: This case report supports the suitability of the bifrontal interhemispheric approach for OGM resection with additional radiation therapy.

The objective of this study was to evaluate the repeatability and reproducibility of anterior chamber volume (ACV) measurements with rotating scheimpflug camera (RSC) and to examine agreement with anterior segment optical coherence tomography (AS-OCT). Methods Thirty nine healthy normal subjects were recruited from the Eye Center of Tongren Hospital. ACV was measured using RSC and AS-OCT in a randomly selected eye for each subject. For RSC measurements, both automatic and manual ACV measurements and 2 independent operators' ACV measurements were obtained. All subjects were invited for 3 visits within a week to evaluate repeatability and reproducibility of ACV measurement by RSC. Agreement was evaluated between RSC and AS-OCT. Results Good repeatability and reproducibility were found for both automatic and manual ACV measurements obtained by RSC. For intrasession repeatability, coefficient of variation (CVw) and intraclass correlation coefficient (ICC) values for automatic were 3.52% and 0.98; the values for manual were 3.44% and 0.97, respectively. For intersession reproducibility, the respective CVw and ICC values were 3.96% and 0.96. Good agreement was also found in 2 operators for both automatic and manual ACV measurements; nevertheless, poor agreement was found between RSC and AS-OCT (95% confidence interval (CI) for agreement of automatic RSC measurement versus AS-OCT were -96.3 to 72.8 μl and 95% CI for agreement of manual RSC measurement versus AS-OCT were between -41.7 to 10.1 μl). Conclusions Both RSC automatic and manual ACV measurements showed good repeatability and reproducibility, and showed comparable agreement between 2 independent operators, but poor agreement was found between RSC and AS-OCT.

    Full Text Available Anterior palatal fistulae or residual anterior clefts are a frequent problem following palatoplasty. Various techniques have been used to repair such fistulae, each having its own advantages and disadvantages. We have successfully used orbicularis oris musculomucosal flap to close anterior fistula and residual clefts in 25 patients. This study shows the superiority of this flap over other techniques because of its reliable blood supply, easy elevation and transfer to fistula site and finally because it is a single-stage procedure.

    Full Text Available Controversy surrounds the remnant-preserving anterior cruciate ligament surgery. Advantages of remnant preservation have been reported in regard to better healing and knee function, although no consensus has been reached. This review article discussed the value and meaning of anterior cruciate ligament remnant preservation in several sections such as effects on healing, remnant classification, biomechanical evaluation, relation to proprioception, animal studies, and clinical studies. We hope that this review will facilitate further discussion and investigation for better treatment of anterior cruciate ligament injuries. So far, the current reviews have not provided sufficient scientific evidence to support the value of preserving the remnant.

    Full Text Available Enlargement of the mediastinal lymphatic glands is a common presentation of intrathoracic tuberculosis (TB in children. However, usually, the mediastinal TB nodes enlarge to 2.8 ± 1.0 cm. In this report, we describe a case of anterior mediastinal lymphnode TB seen as huge mass (7 cm on computed tomography (CT thorax without respiratory or food pipe compromise despite anterior mediastinum being an enclosed space. CT guided biopsy of the mass cultured Mycobacterium TB complex which was resistant to isoniazide, rifampicin, streptomycin ofloxacin, moxifloxacin, and pyrazinamide. Hence, we report primary multi drug resistant TB presenting as anterior mediastinal mass as a rare case report.

    Full Text Available Las depresiones de la región condroesternal, conocidas como tórax en embudo o pectus excavatum, son una de las anomalías congénitas mas frecuentes de la pared anterior del tórax. Su corrección ha sido siempre quirúrgica, para lo cual están descritas varias técnicas que pueden clasificarse en dos grupos: 1 Las que actúan modificando la anatomía costal y esternal y 2 Las que se limitan a disimular el defecto mediante rellenos. Ante casos de pectus excavatum en adultos, en los que se ha descartado totalmente la problemática cardiorrespiratoria y que por consiguiente, consideramos como un problema estético, estamos empleando desde hace 8 años una técnica consistente en la aplicación de prótesis de silicona hechas a medida, con resultados muy satisfactorios y con un nivel de complicaciones prácticamente nulo.The depressions in the chondrosternal region, known as pectus excavatum, are the most usual congenital problems of the anterior chest-wall. Its correction has always been surgical, using two different techniques, as follows: 1 The ones that works changing the costal anatomy; and 2 The ones that just covers the defect up with fillers. For those cases of pectus excavatum in adults, in which the cardiorespiratory problems have been completely ruled out, and are considered as aesthetic problems, we have been using a corrective technique for the last 8 years with a made to measure silicone prosthesis, with very satisfactory results and with almost no complications.

    Full Text Available El tratamiento quirúrgico para la corrección de las orejas prominentes o valgas se basa en crear una distancia de entre 17-21 mm entre el hélix y la mastoides, así como recrear unos pliegues auriculares anteriores bien definidos. Desde finales de 1800 hasta la actualidad se han descrito muchas técnicas para corregir las orejas despegadas, prominentes o valgas, cada una de ellas con sus propias características. En el presente trabajo describimos una técnica para estabilizar el resultado quirúrgico cuando se corrige esta entidad y evitar su recidiva. Se trata de un procedimiento de fijación mastoidea de la oreja mediante un colgajo dermo-graso-pericóndrico de sencillo diseño, útil, seguro y fácilmente reproducible. Hemos empleado esta técnica durante más de 15 años y creemos que ha resistido la prueba del tiempo.The treatment for the correction of prominent or valgus ears, is to create a normal distance (17-21 mm between the mastoid and the helix and a normal appearance of the anterior auricular folds. From late 1800 to the present, many surgical techniques for correcting prominent or valgus ears have been described, each one with its own characteristics. We describe a technique to stabilize the result and prevent recurrence. This technique stabilizes the correction of the ear fixing it to the mastoid fascia using a dermalfat-perichondrium flap of simple design, useful, safe and easily reproducible. We have used it over 15 years, and that makes us believe that has stood the test of time.

  11. Anterior Cruciate Ligament Injuries in Wakeboarding

    Science.gov (United States)

    Starr, Harlan M.; Sanders, Brett

    2012-01-01

    Background: Wakeboarding is an increasingly popular sport that involves aggressive stunts with high risk for lower extremity injury, including anterior cruciate ligament (ACL) rupture. Little has been reported on prevalence or mechanism of ACL injury while wakeboarding. Hypothesis: The prevalence of ACL injury in wakeboarding approaches that of other high-risk sports. Analyzing the mechanism of ACL injury may aid in future efforts of prevention. Study Design: Descriptive epidemiology study. Methods: In sum, 1580 surveys were sent internationally to professional and amateur wakeboarders. The survey questioned the participants on their history of an ACL tear while wakeboarding and asked them to describe the mechanism of injury and treatment. Results: A total of 123 surveys were returned. Of this group, 52 (42.3%) acknowledged having had an ACL tear while wakeboarding. The majority described feeling a pop or buckle after attempting to land a high jump. Only 5 participants (13.5%) described a rotational mechanism created by catching the board edge in the water. Thirty-seven participants (71.15%) said that the injury ruined their ability to wakeboard before reconstruction, and 41 (78.85%) had the injury repaired surgically. Conclusion: The prevalence of ACL tears in this data set, 42.3%, is the highest reported in the literature for wakeboarding and one of the highest for any sport. The main mechanism of injury appears to involve axial compression while one lands in a provocative position; it is not related to a rotational force created by fixed bindings. The injury should be surgically repaired to effectively continue the sport. Further study is needed to determine if wakeboarding represents a high-risk sport for ACL injury. Clinical Significance: Wakeboarding may be a high-risk sport for ACL injury. Noncontact axial compression appears to be the main mechanism of injury. PMID:23016104

    Crowned odontoid process and osteoarthrosis of the anterior atlantoaxial joint. The so-called peridentale aureole ( crowned odontoid ), a horseshoelike calcification around the odontoid process, can occasionally be shown on transbuccal views of the occipito-atlantoaxial region, but is commonly only seen on a.p. tomography in patients with osteoarthrosis of the anterior atlantoxial joint. Tomographic examinations reveal that these irregular horseshoe-like calcifications around the odontoid peg represent mainly the osteophyte formation on the superior border of the anterior arch of the atlas. These calcifications are often surrounding a smaller calcification on the tip of the odontoid peg sometimes with a bucket-handle appearance corresponding to the ostephyte formation on the odontoid process. The peridentale aureole or crowned odontoid process is easily overlooked unless tomography is performed, and misinterpretations are possible if the radiologist is not familiar with this appearance of osteoarthrosis and some other joint diseases of the anterior atlantoaxial joint.

    With the aim of determining the frequency and radiographic features of anterior chest wall involvement in patients with pustulosis palmoplantaris, a questionnaire was sent to 107 patients. Ninety-three patients returned the questionnaire, five of whom were excluded from further analysis due to the appearance of psoriatic lesions. Twenty-five (28%) of the remaining 88 patients reported pain and/or swelling of joints or bones in the anterior chest wall. All were examined radiographically, using tomography, and a group of 20 patients without anterior chest wall complaints were examined similarly. Sixteen of the patients with, but none of the patients without, complaints were found to have arthro-osteitis of the anterior chest wall, consisting of diffuse sclerosis of the manubrium sterni in one patient, localized sclerosis in seven patients, and sequelae of arthritis of the sternoclavicular, upper sternocostal and/or manubriosternal joint in eight patients.

    The rehabilitation of an unesthetic smile in the anterior maxilla is always a clinical challenge, especially when an improper shape and size, old restorations, and unesthetic shading are present. In addition, an irregular gingival zenith contour in the anterior maxilla can affect the smile's harmony. Thus, detailed treatment planning is needed to define a functional and esthetic prosthetic rehabilitation. This study describes a clinical case in which a 55-year-old woman was rehabilitated using Digital Smile Design planning and full ceramic crowns (metal free) in the anterior zone of the maxilla and mandible. To normalize the gingival zenith, a dynamic compression technique was performed using provisional restorations to condition the gingival tissues and harmonize the proportional length of the anterior upper teeth.

    Objective. To detect histological characteristic of anterior cruciate ligament (ACL) and medial collateral ligament (MCL). Methods. In each of 20 skeletally mature male mongrels and 4 men, the ACL and MCL were examined by standard hematoxylin-eosin procedure and toluidine blue staining for histologic observation. Results. The fibroblasts in medial collateral are elongated to spindle shape and aligned in a row between the bundles of collagenous fibers. Toluidine blue staining is negative. The anterior cruciate ligament demonstrated more heterogenous cell types and arrangement. It had three major cell forms:spindle, round and ovoid type, which were shorter but greater than the cells in medial collateral ligament. Toluidine blue staining was positive in anterior cruciate ligament. Most cells in anterior cruciate ligament were enclosed within lacunae. Conclusion. This study suggests that the ACL has different histological characteristics from MCL, and is more cartilage-like in nature.

    Blepharoptosis is a condition of inadequate upper eyelid position, with a downward displacement of the upper eyelid margin resulting in obstruction of the superior visual field. Levator resection is an effective technique that is routinely used to correct aponeurotic ptosis. The anterior levator resection is the procedure of choice in moderate blepharoptosis when there is moderate to good levator muscle function, furthermore, with an anterior approach, a greater resection can be achieved than by a conjunctival approach. The authors describe a modification in the Putterman technique with a resection done over a plicated elevator, plication that was suggested by Mustardè. The technique has been named as elevator muscle anterior resection. The elevator muscle anterior resection inspires from the Fasanella-Servat operation by the use of a clamp, making the operation simple and predictable.

  6. The role of the anterior commissure in callosal agenesis.

    Barr, Melodie S; Corballis, Michael C

    2002-10-01

    Two individuals with callosal agenesis (J.P. and M.M.) and 10 neurologically normal participants were tested on tasks requiring interhemispheric visual integration. M.M., whose anterior commissure was within normal limits, was much worse at matching colors and letters between visual fields than within visual fields, whereas J.P., whose anterior commissure was greatly enlarged, showed no evidence of interhemispheric disconnection. This suggests that in some cases of callosal agenesis, probably a minority, an enlarged anterior commissure may compensate for the lack of the corpus callosum. Neither acallosal participant showed interhemispheric disconnection on tasks requiring integration of location and orientation, however, suggesting that the anterior commissure plays no role in such tasks. These tasks may depend on subcortical commissures, such as the intertectal commissure.

    Ischemia of the areas supplied by the anterior cerebral artery is relatively uncommon. In addition, combined hemiballismus and masturbation have rarely been reported in patients with cerebrovascular disease. We describe herein a 62-year-old right-handed man simultaneously exhibiting right side hemiballismus and involuntary masturbation with the left hand after bilateral infarction of the anterior cerebral artery territory. Right side hemiballismus was related to the disruption of afferent fibers from the left frontal lobe to the left subthalamic nucleus. Involuntary masturbation using the left hand was exclusively linked to a callosal type of alien hand syndrome secondary to infarction of the right side of the anterior corpus callosum. After 2 weeks, these abnormal behaviours were completely extinguished. This report stresses the wide diversity of clinical manifestations observed after infarction of the anterior cerebral artery territory.

    1995-01-01

    Acute compartment syndromes usually occur as a complication of major trauma. While the chronic exertional anterior tibial compartment syndrome is well described in the sports medicine literature, reports of acute tibial compartment syndromes due to physical exertion, or repetitive microtrauma, are rare. The case of an adolescent female who developed an acute anterior compartment syndrome from running in a soccer game is described in this report. Failure to recognize the onset of an acute exertional compartment syndrome may lead to treatment delay and serious complications. Whereas the chronic exertional anterior compartment syndrome is characterized by pain that diminishes with the cessation of exercise, the onset of the acute exertional anterior compartment syndrome is heralded by pain that continues, or increases, after exercise has stopped. Compartment pressure measurement confirms the clinical diagnosis and helps guide treatment. True compartment syndromes require urgent fasciotomy.

  9. Case study: limitations of panoramic radiography in the anterior mandible.

    LENUS (Irish Health Repository)

    Walker, Cameron

    2009-12-01

    Dental Panoramic Tomography (DPT) is a widely used and valuable examination in dentistry. One area prone to artefacts and therefore misinterpretation is the anterior region of the mandible. This case study discusses a periapical radiolucency related to lower anterior teeth that is discovered to be a radiographic artefact. Possible causes of the artefact include a pronounced depression in the mental region of the mandible or superimposition of intervertebral spaces. Additional limitations of the DPT image include superimposition of radio-opaque structures, reduced image detail compared to intra-oral views and uneven magnification. These problems often make the DPT inappropriate for imaging the anterior mandible. Clinical Relevance: Panoramic radiography is often unsuitable for radiographic examination of the anterior mandible.

    Full Text Available Seeds used to plant wheat, corn and rice crops in Brazil are treated with the insecticide carbofuran associated with the dye rhodamine B, attracting granivorous birds and causing mortality during sowing. The objective of this study was to evaluate if using camouflaged seeds can minimize mortality caused by the ingestion of seeds with carbofuran. Alternatives for reducing mortality, such as using carbofuran without rhodamine B or replacing carbofuran by carbosulfan, were compared. Three experiments were carried out in regions of known bird mortality in the states of Paraná and São Paulo, Brazil, using conventional sowing over plowed soil in the traditional planting system, 15,896 kg of seeds in 111.46 ha. Bird carcasses were collected and dissected to unveil which poisoned seed treatments had caused birds' deaths. The mortality mounted to 296 birds of 11 species. Eared doves were the most numerous casualties (263. There was significant correlation between mortality and number of consumed seeds. The consumption of camouflaged seeds was lower than that of commercial seeds treated with rhodamine B. The mortality caused by seeds with both rhodamine B and carbofuran was higher than mortality caused by seeds camouflaged only with carbofuran. The replacement of carbofuran with carbosulfan also seemingly reduced mortality, but carbosulfan mortality might have been underestimated as a result of the apparent movement of affected birds after exposure. Seeds treated with carbofuran and rhodamine B and without any dye, were attractive. Because legal requirement for seeds treated with pesticides to be differentiated by dying, the substitution of rhodamine B by camouflaging must be encouraged.Plantações de trigo, milho e arroz no Brasil utilizam sementes tratadas com o inseticida carbofuran, associado ao corante rodamina B, que é atrativo às aves granívoras, causando notável mortalidade durante o plantio.

    The use of antibody to vascular endothelial growth factor to treat neovascular glaucoma yields good anatomic results in most cases. However, this type of glaucoma can cause angle closure with decompensation of intraocular pressure secondary to fibrovascular tissue contraction in the anterior chamber. Our surgical technique treats the cause by removing the anterior chamber fibrous complex after administration of antibody to vascular endothelial growth factor, thus restoring the chamber angle.

    2014-01-01

    Conclusions: The novel finding of an asymmetry in morphology of the anterior visual system following long-term survival from early monocular enucleation indicates altered postnatal visual development. Possible mechanisms behind this altered development include recruitment of deafferented cells by crossing nasal fibres and/or geniculate cell retention via feedback from primary visual cortex. These data highlight the importance of balanced binocular input during postnatal maturation for typical anterior visual system morphology.

    Purpose: We tried to find out the relevance of anterior mandibular body ostectomy in deformities of the mandible specially prognathism, which is primarily limited to anterior part only. Patients and Methods: Ten patients with skeletal deformity along with malocclusion, which was limited to anterior body of mandible were selected. Selected patients had proper molar interdigitation (even if class 3) and in general had anterior crossbite (except one). All patients had crossed their growth spurts and had no hormonal influence on facial deformity. Specific protocol, including cephelometric analysis cephalometry for orthognathic surgery, prediction tracing and model surgeries were devised. Pre and post-surgical orthodontics and body ostectomy were performed in all patients along with 18-month post-op follow-up. Results: There was significant reduction in prognathism and horizontal dysplasia in all ten patients. Anterior crossbite as well as axis of incisiors over mandibular plane was corrected in all patients due to decrease in length of mandibular body. All patients showed decreased facial height and better lip competence with intact posterior occlusion and no (negligible or transient) sensory loss. Conclusions: Our study could confirm that people whose deformity is limited to the anterior part of mandible with reasonable occlusion posteriorly can get satisfactory cosmetic and functional results through body ostectomy alone rather than going for surgical procedure in the ramal area, which is liable to cause sensory and occlusal disturbances.

    It is customary to perform medial meniscus repair before anterior cruciate ligament (ACL) graft placement when undertaken as a combined procedure. However, in chronic ACL-deficient knees, intraoperative anterior tibiofemoral translation can cause the medial meniscus repair to be more technically challenging. Intraoperative anterior tibiofemoral translation can both reduce the visualization of the medial meniscus and make its reduction unstable. An operative sequence alteration of ACL graft placement and tensioning before medial meniscal repair improves medial meniscus visualization in chronically ACL-deficient knees by using the ACL graft's ability to prevent anterior tibiofemoral translation. The technique sequence is as follows: (a) the medial meniscus is reduced, (b) ACL reconstruction is undertaken using a hamstring graft without final tibia fixation,

    Objective. To demonstrate the MRI findings of an anterior shoulder capsular avulsion from the humerus, with or without subscapularis rupture, after anterior dislocation or severe abduction external rotation injury. Design and patients. We retrospectively reviewed the MRI and MR arthrographic examinations of seven patients who were identified at surgery with avulsion of the anterior shoulder stabilizers from the humerus. MRI was correlated with clinical history and surgical results. Results. MRI findings included: inhomogeneity or frank disruption of the anterior capsule at the humeral insertion (all), fluid intensity anterior to the shoulder (six patients), tear of the subscapularis tendon (six patients), dislocation of the biceps tendon (four patients), and a Hill-Sachs deformity (four patients). MR arthrography additionally found extravasation of contrast through the capsular defect (two patients). Conclusions. Our findings suggest that MRI is helpful for diagnosing humeral avulsion of the anterior glenohumeral capsule, especially when a tear of the subscapularis tendon insertion is present. MR arthrography may be of benefit for diagnosing capsular avulsion without associated subscapularis tendon abnormality. (orig.). With 4 figs.

    Anteriorly displaced anus is an anomaly that is debated with regard to its nomenclature, diagnosis and management. To describe MRI anatomy of the anal canal in children with anteriorly displaced anus and its impact on the process of defecation. We prospectively examined ten children (7 girls, 3 boys; age range 7 months to 8 years, mean 3 years) with anteriorly displaced anus between August 2009 and April 2012. Noncontrast MRI examinations were performed on a 1.5-T magnet. T1- and T2-weighted turbo spin-echo images were acquired in axial, sagittal and coronal planes of the pelvis. The anorectal angle and the relative hiatal distance were measured in mid-sagittal images, and compared with those of a control group using the Mann-Whitney test. In children with anteriorly displaced anus, no anatomical abnormality was depicted at the level of the proximal anal canal. However, the distal anal canal was displaced anteriorly, running out its external muscle cuff, which remained un-displaced at the usual site of the anus. This changes the orientation of the central axis of the anal canal by passing across instead of along the fibers of the longitudinal muscle coat. Children with anteriorly displaced anus had a more obtuse anorectal angle (mean 112.1 ), which was significantly greater than that of the control group (mean 86.2 ). MRI is a valuable tool in studying the anatomy of the anal canal in children with anteriorly displaced anus. The abnormal orientation of the longitudinal muscle across the anal canal can explain the obstructed defecation in these children. Based on this study, it might be of interest to use MRI in studying equivocal cases and children with unexplained constipation. (orig.)

No presente trabalho procurou-se verificar o efeito de sete fungicidas, aplicados em pulverizaçao a alto volume, no controle do tombamento causado por Cylindroctadium sp. e Fusarium sp. em mudas E. saligna Sm. nas sementeiras. O delineamento experimental usado foi o de blocos casualizados com quatro repetições. As sementes foram desinfectadas com Neantina seco a 0,3% e o leito da sementeira foi tratado com Brometo de metila (40ml/m² e depois inoculado com Cylindroctadium sp Fusarium sp. em meio de fubá-areia. Observou-se que os tratamentos mais eficientes no controle do tombamento foram Arasan — 75 a 0,3%, Cupravit azul a 0,4% e Miltox a 0,35% enquanto que o Batasan a 0,15% foi o mais fitotóxico. As plântulas apresentaram melhor aspecto vegetativo nas parcelas tratadas com Ferradol a 0,25%.

    Full Text Available A routine eye examination of a 69-year-old man revealed a scleral perforation of one of the haptics of the anterior chamber intraocular lens (AC IOL which had been implanted many years ago. The patient was asymptomatic with good visual acuity. His history was negative for any trauma, eye rubbing, topical corticosteroid use, or autoimmune disease. The horizontal and vertical white-to-white diameters of the cornea in the right eye were 11.5 and 10.5 mm, respectively. Anterior segment optical coherence tomography showed the anterior chamber length to be 12.28 mm horizontally and 10.63 mm vertically. The patient underwent an IOL exchange, and the length of the explanted AC IOL was measured to be 12 mm. We speculate that the AC IOL, which was vertically aligned, was oversized. This case demonstrates the need for proper sizing and positioning of an AC IOL. In complex cases where AC IOL may be used, measuring the horizontal and vertical lengths of the anterior chamber by anterior segment optical coherence tomography prior to surgery may be useful.

    A retrospective study was performed on patients who underwent myringoplasty for either anterior or subtotal perforations over an 8-year period (from 1994 till 2004). We used the KTP-laser assisted anterior anchoring technique combining with anterior "pull-back" method. Patients' ages ranged from 6-62 years (median 36.5). The mean follow-up period was 2.8 years (minimum 6 months). The audiological results were analysed with the "Pytel software", which was developed in our department. As for the procedure, the drum remnant was freed from the malleus handle with the use of the laser and elevated out of it's sulcus anterior-superiorly. Large fascia graft was fashioned with a split of 4-5 mm in the middle of one edge. The graft was placed using the underlay technique medial to the handle of the malleus. A pull-back tunnel was created at the border of the anterior quadrants to further facilitate the survival of the graft. In this series the graft taking rate was 100%. Reperforation due to an undersized fascia was observed in one case. Post-operative audiological results indicated no bone conduction threshold elevation in any frequencies. Using the laser, cochlear trauma can be prevented, double fixation of the drum prevents lateralisation and blunting. Wide canalplasty makes both the approach and the follow-up very easy. Thorough soft tissue and bone work is advantageous from the fascia taking rate point of view.

    Purpose. To evaluate anterior segment's structures by Pentacam in patients with tilted disc syndrome (TDS). Methods. Group 1 included forty-six eyes of forty-six patients who have the TDS. Group 2 including forty-six eyes of forty-six cases was the control group which was equal to the study group in age, gender, and refraction. A complete ophthalmic examination was performed in both groups. All cases were evaluated by Pentacam. The axial length (AL) of eyes was measured by ultrasound. Quantitative data obtained from these measurements were compared between two groups. Results. There was no statistically significant difference for age, gender, axial length, and spherical equivalent measurements between two groups (p = 0.625, p = 0.830, p = 0.234, and p = 0.850). There was a statistically significant difference for central corneal thickness (CCT), corneal volume (CV), anterior chamber angle (ACA), and pupil size measurements between two groups (p = 0.001, p = 0.0001, p = 0.003, and p = 0.001). Also, there was no statistically significant difference for anterior chamber depth (ACD), anterior chamber volume (ACV), and lens thickness (LT) measurements between two groups (p = 0.130, p = 0.910, and p = 0.057). Conclusion. We determined that CCT was thinner, CV was less, and ACA was narrower in patients with TDS. There are some changes in the anterior segment of the eyes with tilted disc. PMID:27648303

    Recovery following anterior cruciate ligament reconstruction is an arduous process that requires a significant mental and physical commitment to rehabilitation. Orthopaedic research in recent years has focused on optimizing anterior cruciate ligament surgical techniques; however, despite stable anterior cruciate ligament reconstructions, many athletes still never achieve their preinjury ability or even return to sport. Psychological factors associated with patient perceptions and functional outcomes following anterior cruciate ligament reconstruction are important to acknowledge and understand. Issues related to emotional disturbance, motivation, self-esteem, locus of control, and self-efficacy can have profound effects on patients' compliance, athletic identity, and readiness to return to sport. The psychological aspects of recovery play a critical role in functional outcomes, and a better understanding of these concepts is essential to optimize the treatment of patients undergoing anterior cruciate ligament reconstruction, particularly those who plan to return to sport. Identifying at-risk patients, encouraging a multidisciplinary approach to patient care, and providing early referral to a sports psychologist may improve patient outcomes and increase return-to-play rates among athletes.

    An analysis of 606 surgically removed anterior chamber intraocular lens (IOL) specimens revealed that 351 or 58% of these were small-diameter, round loop, closed-loop styles. Because of the extremely high percentage of IOLs with this design received in our laboratory and the correlation of clinical histories with our histopathologic findings, we have concluded that such IOLs do not provide the safety and efficacy achieved by other anterior chamber lens designs. The finely polished, one-piece, all-PMMA styles fared well in our study. Although these one-piece styles comprise well over 50% of the American market share of anterior chamber IOLs, they comprise only 14% of all anterior chamber IOLs accessioned in our laboratory, compared to 58% for closed-loop designs. We believe that implantation of anterior chamber lenses with small-diameter, round, closed loops is no longer warranted. Patients in whom these IOLs have already been implanted should be carefully followed. It is our opinion that the FDA should recall or closely monitor all IOLs of this design and that implantation of closed-loop lenses should be discontinued in the United States. Furthermore, we believe that an IOL deemed to be not medically sound or worthy of implantation in the United States should not be marketed or donated outside of this country.

    The main aim of this research is finding the feature vectors of the anterior and posterior cruciate ligaments (ACL and PCL). These feature vectors have to clearly define the ligaments structure and make it easier to diagnose them. Extraction of feature vectors is obtained by analysis of both anterior and posterior cruciate ligaments. This procedure is performed after the extraction process of both ligaments. In the first stage in order to reduce the area of analysis a region of interest including cruciate ligaments (CL) is outlined in order to reduce the area of analysis. In this case, the fuzzy C-means algorithm with median modification helping to reduce blurred edges has been implemented. After finding the region of interest (ROI), the fuzzy connectedness procedure is performed. This procedure permits to extract the anterior and posterior cruciate ligament structures. In the last stage, on the basis of the extracted anterior and posterior cruciate ligament structures, 3-dimensional models of the anterior and posterior cruciate ligament are built and the feature vectors created. This methodology has been implemented in MATLAB and tested on clinical T1-weighted magnetic resonance imaging (MRI) slices of the knee joint. The 3D display is based on the Visualization Toolkit (VTK).

    Persistent fetal vasculature (PFV) is a common congenital developmental anomaly of the eye which results from failure of the embryological primary vitreous and hyaloid vasculature to regress by the time of birth (Int Ophthalmol Clin 48: 53-62, 2008). Typically, it is divided into anterior, posterior or combined types and is characterized by the presence of a vascular stalk located between the optic disc and the posterior lens capsule (Int Ophthalmol Clin 48: 53-62, 2008). Although it has been reported to manifest itself differently, in our case it presented in a microphthalmic eye as anterior segment dysgenesis with broad-based mid-peripheral synechiae, posterior embryotoxon, iridoschisis, ectropion uveae, hypotony and subluxated cataractous lens with a taut anterior hyaloid face which are rare associations with PFV.

  8. Anterior Segment Imaging in Ocular Surface Squamous Neoplasia

    2016-01-01

    Full Text Available Recent advances in anterior segment imaging have transformed the way ocular surface squamous neoplasia (OSSN is diagnosed and monitored. Ultrasound biomicroscopy (UBM has been reported to be useful primarily in the assessment of intraocular invasion and metastasis. In vivo confocal microscopy (IVCM shows enlarged and irregular nuclei with hyperreflective cells in OSSN lesions and this has been found to correlate with histopathology findings. Anterior segment optical coherence tomography (AS-OCT demonstrates thickened hyperreflective epithelium with an abrupt transition between abnormal and normal epithelium in OSSN lesions and this has also been shown to mimic histopathology findings. Although there are limitations to each of these imaging modalities, they can be useful adjunctive tools in the diagnosis of OSSN and could greatly assist the clinician in the management of OSSN patients. Nevertheless, anterior segment imaging has not replaced histopathology’s role as the gold standard in confirming diagnosis.

    Compartment syndrome rarely follows anterior cruciate ligament reconstruction. However, when it does, it may result in mononeuropathies that are amenable to neurolysis. The authors of this study present an 18-yr-old woman who sustained a right anterior cruciate ligament tear and underwent uneventful anterior cruciate ligament reconstruction using femoral and popliteal nerve blocks. Postoperatively, she developed compartment syndrome requiring emergent fasciotomies. At 11 wks after fasciotomy, results of electrophysiologic tests showed evidence of severe fibular and tibial neuropathies. Magnetic resonance images showed extensive tricompartmental myonecrosis. Fibular and tibial neurolysis as well as decompression were performed, followed by intensive outpatient rehabilitation. At the 6-mo follow-up, she reported resolution of pain as well as significant improvement in sensation, strength, and function. Early recognition and intervention are crucial to prevent serious neurologic damage. Excessive tourniquet pressure and anesthetic nerve blocks may have been responsible.

    Study Design Retrospective case series. Objective Diffuse idiopathic skeletal hyperostosis (DISH) or Forestier disease involves hyperostosis of the spinal column. Hyperostosis involving the anterior margin of the cervical vertebrae can cause dysphonia, dyspnea, and/or dysphagia. However, the natural history pertaining to the risk factors remain unknown. We present the surgical management of two cases of dysphagia secondary to cervical hyperostosis and discuss the etiology and management of DISH based on the literature review. Methods This is a retrospective review of two patients with DISH and anterior cervical osteophytes. We reviewed the preoperative and postoperative images and clinical history. Results Two patients underwent anterior cervical osteophytectomies due to severe dysphagia. At more than a year follow-up, both patients noted improvement in swallowing as well as their associated pain. Conclusion The surgical removal of cervical osteophytes can be highly successful in treating dysphagia if refractory to prolonged conservative therapy.

    During the first step of cataract surgery, the lens capsule is perforated and a circular hole is created with a sharp instrument, a procedure called capsulorhexis. To develop automated systems that can assist ophthalmologists during capsulorhexis, the forces required must be quantified. This study investigates perforation forces of the central anterior lens capsule in porcine eyes, which are used as a conservative model for the human eye. A micro-mechanical characterisation method is presented that measures capsular bag perforation forces with a high precision positioning and high-resolution force sensing system. The force during perforation of the anterior lens capsule was measured with various sized needles and indentation speeds and is found to be 15-35mN. A bio-mechanical model is identified that describes an exponential correlation between indentation force and depth, indicating strain hardening behaviour of the porcine anterior lens capsule.

    Full Text Available The objective of this research was to determine the deterioration rate of BRS 208 and CD 104 wheat cultivar seeds, treated with fungicides, by applying the viability equation. Seeds were stored in conventional warehouses in Mauá da Serra and Londrina, in the State of Paraná, Brazil. Four seed lots were divided into four replications, half being treated with Carboxin + Thiran and the other half taken as controls, without treatment, and these were stored for 300 days. The germination data were transformed into probit, anda straight line was adjusted between 0 and 30 days. The treated seed lot of cv. BRS 208 stored in Londrina gave seed deterioration rates varying from 0.8.10-3 to 1.3.10-3, not differing from the values given for the similar lot stored in Mauá da Serra, of 0.9.10-3.Thedeterioration rates of the treated seed of cv. CD 104 were 1.2.10-3 in Mauá da Serra and 2.0.10-3 in Londrina, which are greater than those values given for untreated seeds of 0.4.10-3 and 0.5.10-3.This model provides an effective approach to predict the untreated and treated seed longevity of wheat for the purpose of managing seeds.O objetivo deste trabalho foi aplicar a equação de viabilidade para determinar a taxa de deterioração e a longevidade das sementes de trigo, tratada com fungicida, das cultivares BRS 208 e CD 104, emarmazenamento convencional, em Mauá da Serra e Londrina, PR.

    Full Text Available Background/Aim. An important element of prosthetic treatment of edentulous patients is selecting the size of anterior artificial teeth that will restore the natural harmony of one’s dentolabial structure as well as the whole face. The main objective of this study was to determine the correlation between the inner canthal distance (ICD and interalar width (IAW on one side and the width of both central incisors (CIW, the width of central and lateral incisors (CLIW, the width of anterior teeth (ATW, the width between the canine cusps (CCW, which may be useful in clinical practice. Methods. A total of 89 subjects comprising 23 male and 66 female were studied. Their age ranged from 19 to 34 years with the mean of 25 years. Only the subjects with the preserved natural dentition were included in the sample. All facial and intraoral tooth measurements were made with a Boley Gauge (Buffalo Dental Manufacturing Co., Brooklyn NY, USA having a resolution of 0.1mm. Results. A moderate correlation was established between the interalar width and combined width of anterior teeth and canine cusp width (r = 0.439, r = 0.374. A low correlation was established between the inner canthal distance and the width of anterior teeth and canine cusp width (r = 0.335, r = 0.303. The differences between the two genders were highly significant for all the parameters (p < 0.01. The measured facial distances and width of anterior teeth were higher in men than in women. Conclusion. The results of this study suggest that the examined interalar width and inner canthal distance cannot be considered reliable guidelines in the selection of artificial upper anterior teeth. However, they may be used as a useful additional factor combined with other methods for objective tooth selection. The final decision should be made while working on dentures fitting models with the patient’s consent.

    Full Text Available ABSTRACT Purpose: To evaluate the difference in terms of refractive errors and anterior segment parameters between schizophrenic patients and healthy volunteers. Methods: This study compared 70 patients (48 men who were diagnosed with schizophrenia with a control group of 60 (35 men who were similar in terms of age, gender, education, and socioeconomic level. Anterior segment examination was performed using a Scheimflug system. Axial length and lens thickness (LT were measured using optic biometry. The following tests were administered to the psychiatric patient group: Brief Psychiatric Rating Scale (BPRS, Scale for the Assessment of Negative Symptoms (SANS, and Scale for the Assessment of Positive Symptoms (SAPS. Results: Mild myopia was detected in both the schizophrenic and control groups, with no statistically significant difference (p>0.005. Corneal volume (CV, anterior chamber volume (ACV, anterior chamber depth (ACD, and central corneal thickness (CCT values were lower in the schizophrenic group, and there was a statistically significant between-group difference (p=0.026, p=0.014, p=0.048, and p=0.005, respectively. LT was greater in schizophrenics, and the difference was found to be statistically significant (p=0.006. A statistically significant negative correlation was found between SAPS and cylinder values (p=0.008. The axial eye length, cylinder value, pupil diameter, mean keratometric value, and anterior chamber angle revealed no statistically significant difference between the groups (p>0.05. Conclusion: No statistically significant difference was detected in terms of refraction disorders between schizophrenics and the healthy control group, while some differences in anterior chamber parameters were present. These results demonstrate that schizophrenics may exhibit clinical and structural differences in the eye.

    Objective: To evaluate the safety and efficacy of new modality of anterior skull base repair,namely sandwich-like reconstruction of anterior skull base defects. Methods: A retrospective analysis of patients who underwent transcranial or transcranial-facial resections of malignant or benign aggressive tumors involving the anterior skull base was conducted in our department. We used the sandwich-like reconstruction, using pedicled pericranial flap, frontal muscle flap and free abdominal adipose tissue between them, to separate of cranial cavity and aerodigest tract and keep the frontal lobes in place following resections of anterior skull base tumors. Results: From October, 1984 to October, 1998, 116 patients underwent transcranial or transcranialfacial approach for the resection of malignant or aggressive benign tumor, and sandwich-like repairs were performed for the anterior skull base defect. 54 (46.6 % ) patients had previous operation, with a maximum of 5 surgeries. The average age of patients was 35.9 years old, ranging form 6 to 73 years old. Forty-eight (41.4%)patients had malignant neoplasmas, and sixty-eight (58.6%) patients had benign aggressive tumors. In our series, with the maximal follow-ups for as long as 14 years, NO one had early failure of the one-stage reconstruction. CSF fluid leakage was not encountered, nor was ascending bacterial meningitis observed. No immediate or delayed prolapse of dura or frontal lobes was observed. Conclusion: We conclude that the sandwich-like reconstruction, using pericranial flap, frontal muscle flap and free abdominal adipose between them, is an extremely safe and effective procedure for the repair of skull base defect, even when tumor extensively involves anterior skull base.

In our series, with the maximal follow-ups for as long as 14 years, NO one had early failure of the one-stage reconstruction. CSF fluid leakage was not encountered, nor was ascending bacterial meningitis observed. No immediate or delayed prolapse of dura or frontal lobes was observed. Conclusion: We conclude that the sandwich-like reconstruction, using pericranial flap, frontal muscle flap and free abdominal adipose between them, is an extremely safe and effective procedure for the repair of skull base defect, even when tumor extensively involves anterior skull base.

    Introduction Gonioscopy is the gold standard in assessing anterior chamber angles. However, interobserver variations are common and there is a need for reliable objective method of assessment. Aim To compare the anterior chamber angle by gonioscopy and Spectral Domain Optical Coherence Tomography (SD-OCT) in individuals with shallow anterior chamber. Materials and Methods This comparative observational study was conducted in a rural tertiary multi-speciality teaching hospital. A total of 101 eyes of 54 patients with shallow anterior chamber on slit lamp evaluation were included. Anterior chamber angle was graded by gonioscopy using the shaffer grading system. Angles were also assessed by SD-OCT with Trabecular Iris Angle (TIA) and Angle Opening Distance (AOD). Chi-square test, sensitivity, specificity, positive and negative predictive value to find correlation between OCT parameters and gonioscopy grading. Results Females represented 72.7%. The mean age was 53.93 ±8.24 years and mean anterior chamber depth was 2.47 ± 0.152 mm. Shaffer grade ≤ 2 were identified in 95(94%) superior, 42(41.5%) inferior, 65(64.3%) nasal and 57(56.4%) temporal quadrants. Cut-off values of TIA ≤ 22° and AOD ≤ 290 μm were taken as narrow angles on SD-OCT. TIA of ≤ 22° were found in 88(92.6%) nasal and 87(87%) temporal angles. AOD of ≤ 290 μm was found in 73(76.8%) nasal and 83(83%) temporal quadrants. Sensitivity in detecting narrow angles was 90.7% and 82.2% for TIA and AOD, while specificity was 11.7% and 23.4%, respectively. Conclusion Individuals were found to have narrow angles more with SD-OCT. Sensitivity was high and specificity was low in detecting narrow angles compared to gonioscopy, making it an unreliable tool for screening. PMID:27190851

    All patients undergoing cruciate-retaining primary total knee arthroplasty for degenerative osteoarthritis at one center were studied prospectively. Clinical and radiographic followup was obtained at a minimum 5 years in 102 knees in 73 patients. Patients were asked specifically about the presence of the pain in the anterior aspect of the knee in the vicinity of the patella and rated the severity of the pain on a visual analog scale. Significant anterior knee pain rating at least 3 of 10 on the visual analog scale was present in 16 knees (13 patients). Eleven patients with 14 symptomatic knees agreed to undergo computed tomography scanning to accurately determine the rotation of the tibial and femoral components. The epicondylar axis and tibial tubercle were used as references using a previously validated technique. A control group of 11 asymptomatic patients (14 knees), matched for age, gender, and length of followup also underwent computed tomography scanning. All patients in both groups had normal axial alignment. There was a highly significant difference in tibial component rotation between the two groups with the patients with anterior knee pain averaging 6.2 degrees internal rotation compared with 0.4 degrees external rotation in the control group. There also was a significant difference in combined component rotation with the patients with anterior knee pain averaging 4.7 degrees internal rotation compared with 2.6 degrees external rotation in the control group. There was no significant difference in the degree of radiographic patellar tilt or patellar subluxation between the two groups. Patients with combined component internal rotation were more than five times as likely to experience anterior knee pain after total knee arthroplasty compared with those with combined component external rotation. Component malrotation is a significant factor in the development of anterior knee pain after total knee arthroplasty.

    Full Text Available Objective To study the clinical manifestations, pathologic features, diagnosis, treatment and prognosis of primary synovial sarcoma in the anterior mediastinum. Methods A case of primary synovial sarcoma in the anterior mediastinum was reported. Clinical features, imaging manifestations, pathology features and therapeutic effect were analysed and the relevant literature was reviewed. Results A 48-year-male patient was admitted with complaint of right chest pain for 4 days. Chest computerized tomography revealed a large mass located at the right anterior mediastinum, and it was primarily diagnosed as invasive thymoma. Pathological examination by CT-guided percutaneous needle biopsy manifested that, under microscope, the tumor cells were short and spindle in shape forming a nest structure, suggested it was a thymoma. The patient then underwent resection of thymoma with removal of fat and connective tissue in the anterior mediastinum. During the operation the size of the tumor was 15cm×15cm×10cm, being located at the anterior mediastinum, and it tended to bleed. The diagnosis of primary monophasic synovial sarcoma in the mediastinum was confirmed by postoperative/pathology examination. Immunohistochemistry staining showed that the tumor cells were positive for the markers Bcl-2 and EMA, but negative for the markers CK (pan and S100. The patient suffered from local recurrence with metastases to lung 4 months after surgery. The patient received 2 chemotherapeutic courses with ifosfamide, epirubicin and cisplatin. He died 6 months after surgery. Conclusion Primary synovial sarcoma in the anterior mediastinum is an extremely rare and highly malignant tumor with poor prognosis. The diagnosis depends on the pathological features, immunohistochemistry and RT-PCR. Radical resection combined with comprehensive treatment may improve the survival rate.

    The brain creates a model of the world around us. We can use this representation to perceive and comprehend what we see at any given moment, but also to vividly re-experience scenes from our past and imagine future (or even fanciful) scenarios. Recent work has shown that these cognitive functions — perception, imagination and recall of scenes and events — all engage the anterior hippocampus. Here we capitalise on new findings from functional neuroimaging to propose a model that links high-level cognitive functions to specific structures within the anterior hippocampus. PMID:26865022

    Full Text Available Treatment planning for patients with skeletal deformities is often considered challenging. This article reports a female patient with achondroplasia who presented with severe maxillary retrognathism and vertical excess along with anterior open bite. The clinical and cephalometric findings of the patient are detailed here. The treatment plan consisted of modified anterior maxillary osteotomy for simultaneous vertical and sagittal augmentation along with orthodontic intervention. The course of surgical-orthodontic treatment and the results are presented. This treatment is to be followed by correction of vertical maxillary excess after completion of growth. This paper concludes that the dentoalveolar component of a skeletal deformity can be handled independent of the craniofacial management.

  9. Proprioception in anterior cruciate ligament deficient knees and its relevance in anterior cruciate ligament reconstruction

    Directory of Open Access Journals (Sweden)

    Mandeep S Dhillon

    2011-01-01

    Full Text Available Injury to the anterior cruciate ligament (ACL not only causes mechanical instability but also leads to a functional deficit in the form of diminished proprioception of the knee joint. "Functional" recovery is often incomplete even after "anatomic" arthroscopic ACL reconstruction, as some patients with a clinically satisfactory repair and good ligament tension continue to complain of a feeling of instability and giving way, although the knee does not sublux on clinical testing. Factors that may play a role could be proprioceptive elements, as the intact ACL has been shown to have significant receptors. Significant data have come to light demonstrating proprioceptive differences between normal and injured knees, and often between injured and reconstructed knees. ACL remnants have been shown to have proprioceptive fibers that could enhance functional recovery if they adhere to or grow into the reconstructed ligament. Conventionally the torn remnants are shaved off from the knee before graft insertion; modern surgical techniques, with remnant sparing methods have shown better outcomes and functional recovery, and this could be an avenue for future research and development. This article analyzes and reviews our understanding of the sensory element of ACL deficiency, with specific reference to proprioception as an important component of functional knee stability. The types of mechanoreceptors, their distribution and presence in ACL remnants is reviewed, and suggestions are made to minimize soft tissue shaving during ACL reconstruction to ensure a better functional outcome in the reconstructed knee.

    Full Text Available Estudou-se o efeito do extrato aquoso de folhas de nim sobre o desenvolvimento e a mortalidade de lagartas recém-eclodidas de Spodoptera frugiperda. Para constatação do efeito de contato e de ingestão, as lagartas foram pulverizadas e as folhas de milho submersas no extrato (10 mg.mL-1 em laboratório e/ou pulverizadas no campo com um pulverizador de CO2. Partes de folhas de milho tratadas foram colocadas em copos plásticos para alimentar as lagartas e trocadas a cada dois dias. Adjuvantes foram adicionados ao extrato visando melhorar sua aderência às superfícies tratadas. Os parâmetros avaliados foram a mortalidade e o desenvolvimento larval. As folhas de milho submergidas e pulverizadas com o extrato causaram elevada mortalidade (100% e prejudicaram o desenvolvimento das lagartas sobreviventes. Na avaliação realizada 10 dias após a aplicação, o espalhante adesivo e o óleo de soja misturados ao extrato melhoraram a eficiência deste. A mortalidade das lagartas ocorreu três dias após a aplicação do extrato e a sua pulverização diretamente sobre o inseto não prejudicou o desenvolvimento larval. O extrato aquoso de nim mostrou-se com potencial para o controle de S. frugiperda.The effect of aqueous extracts from neem leaves and spraying adjuvants were evaluated on development and mortality of neonate S. frugiperda larvae.

    Full Text Available OBJECTIVE: To evaluate the complications of anterior approach to the cervical spine in patients who underwent cervical arthrodesis with instrumentation. METHODS: Prospective and descriptive study was conducted from January 2009 to April 2010. All patients who underwent arthrodesis of the cervical spine by anterior approach were included, regardless the diagnosis. Access was made by the anterior approach on the right side. We evaluated the number of operated levels (1, 2 or 3 levels and, the type of procedure performed: discectomy and placement of cage and plate (D+C+P, discectomy with placement of a cage (D+C or corpectomy with placement of cage and plate (C+C+P. All complications related to surgical approach were reported. RESULTS: We studied 34 patients, 70% male. The average age was 50 years and mean follow-up was 8 months. Eighteen percent of patients had complications, distributed as follows: dysphasia (33% and dysphonic (67%. Among patients who developed complications, most underwent to D+C+P (83% and no complications were found in patients where no cervical plate was used. Regarding levels, both complications were identified in patients operated to one or two levels. However, in patients operated on three levels, only dysphonia was identified. CONCLUSION: The most frequent complication was dysphonia. Patients who presented more complications were those undergoing discectomy and fusion with cage and anterior cervical plate. All cases of dysphonia were in this group. The number of accessible levels does not seem to have affected the incidence of complications.

    Full Text Available Michitaka Sugahara, Takayuki Fujimoto, Kyoko Shidara, Kenji Inoue, Masato Wakakura Inouye Eye Hospital, Tokyo, Japan Introduction: Here, we describe a patient who presented with anterior ischemic optic neuropathy (AION and subsequently developed uveitis. Case: A 69-year-old man was referred to our hospital and initially presented with best-corrected visual acuities (BCVA of 20/40 (right eye and 20/1000 (left eye and relative afferent pupillary defect. Slit-lamp examination revealed no signs of ocular inflammation in either eye. Fundus examination revealed left-eye swelling and a pale superior optic disc, and Goldmann perimetry revealed left-eye inferior hemianopia. The patient was diagnosed with nonarteritic AION in the left eye. One week later, the patient returned to the hospital because of vision loss. The BCVA of the left eye was so poor that the patient could only count fingers. Slit-lamp examination revealed 1+ cells in the anterior chamber and the anterior vitreous in both eyes. Funduscopic examination revealed vasculitis and exudates in both eyes. The patient was diagnosed with bilateral panuveitis, and treatment with topical betamethasone was started. No other physical findings resulting from other autoimmune or infectious diseases were found. No additional treatments were administered, and optic disc edema in the left eye improved, and the retinal exudates disappeared in 3 months. The patient's BCVA improved after cataract surgery was performed. Conclusion: Panuveitis most likely manifests after the development of AION. Keywords: anterior ischemic optic neuropathy, uveitis

    Full Text Available Purpose: The aim of this study was to investigate possible predictive factors related to anterior chamber fibrin formation after vitreoretinal surgery in a large series of patients. Methods: The data of 185 eyes of 185 patients submitted to vitreoretinal surgery was reviewed. The following variables were evaluated: the postoperatively presence of fibrin, age, diabetes mellitus, the vitrectomy system gauge (20, 23 or 25 gauge, the type of vitreous substitute, the influence of prior surgical procedures and the combination with cataract extraction. To evaluate predictive factors for anterior chamber fibrin formation, univariate analysis was performed. A multivariate stepwise logistic regression model was adjusted to investigate factors associated with fibrin formation (p<0.05. Results: Fibrinoid anterior chamber reaction was found in 12 (6.4% patients. For multivariate logistic regression analysis, balanced salt solution (BSS, the chance of fibrin occurrence was 5 times greater (odds ratio 4.83, CI 95% 1.302 - 17.892; p=0.019, while combination with phacoemulsification increased the chance of fibrin formation by 20 times (odds ratio 20, CI 95% 2.480 - 161.347; p=0.005. No significant difference was found regarding other variables. Conclusion: Anterior chamber fibrin formation is an unwanted complication after vitreoretinal surgery. Factors such as combined performance of phacoemulsification and the use of balanced salt solution as a vitreous substitute may predispose the occurrence of this complication.

    Full Text Available Background: Recent trends put estheticrehabilitationas a demandingtreatmentin order to correct malpositionedanteriordentition. This is enhanced by the patient’s background, especially careers that require prime appearance for the public. Purpose: To describe that even though there are many treatment alternatives and procedures, esthetic rehabilitation on crowded and protruded anterior dentition using endodontic treatment, cast posts and all ceramic crowns, can improve patient’s appearance. Case: This article presents a case report on esthetic rehabilitation of crowded and protruded anterior dentition. Treatment was done due to patient’s refusal in receiving orthodontic treatment. The patient requested esthetic rehabilitation as an expectation for faster and instant esthetic result. Case management: Endodontic treatment was done to the involved dentition prior to the final restoration. Cast posts and all ceramic crowns were used as final restoration to correct the crowded and protruded anterior teeth. Conclusion: Esthetic rehabilitation can be done successfully on crowded and protruded anterior dentition. Instant result could be achieved by this treatment. This is supported by the fact that dentists should be aware of not only choosing the right treatment and materials but also patient’s expectations and conditions.

  15. Holistic approach to understanding anterior knee pain. Clinical implications.

    2014-10-01

    Anterior knee pain is one of the most frequent reasons for consultation within knee conditions. The aetiology is not well known, which explains the sometimes unpredictable results of its treatment. Normally, when we see a patient in the office with anterior knee pain, we only study and focus on the knee. If we do this, we are making a big mistake. We must not forget to evaluate the pelvis and proximal femur, as well as the psychological factors that modulate the course of the illness. Both the pelvifemoral dysfunction as well as the psychological factors (anxiety, depression, catastrophization and kinesiophobia) must be included in our therapeutic targets of the multidisciplinary treatment of anterior knee pain. We must not only focus on the knee, we must remember to "look up" to fully understand what is happening and be able to solve this difficult problem. The aetiology of anterior knee pain is multifactorial. Therefore, diagnosis and treatment of patellofemoral disorders must be individualized. Our findings stress the importance of tailoring physiotherapy, surgery and psycho-educational interventions to each patient.

    Full Text Available BACKGROUND Anterior Cruciate Ligament (ACL tear is the most common serious ligamentous injury to the knee joint. Anterior Cruciate Ligament (ACL injury is quite common among young active population, athletes and contact sports. The exact incidence of anterior cruciate ligament tears is not known as the cases are being under reported. The ACL is the primary stabilizer against anterior translation of the tibia on the femur and is important in counteracting rotation and valgus stress. MATERIALS AND METHODS Between November 2012 to October 2014, 34 consecutive patients who underwent arthroscopic assisted ACL reconstructions in the Department of Orthopedics and Traumatology, King George Hospital, Visakhapatnam were the material in our study. Age groups between 18 to 45 years considered. We utilised both BPTB and Quadrupled hamstring graft depending on the patient’s age, outcome testing in all cases was performed at the latest follow-up (at least 6 months. Post-operative physiotherapy rehabilitation protocol followed for 06 months. RESULTS Standard protocol of Lysholm and IKDC knee scoring system were used for evaluation of the results of the surgery during followup. Patients were evaluated periodically at preop, 3 months, 6 months, 12 months, 18 months and 24 months. CONCLUSION Patients with isolated ACL injury had better outcome compared to patients who underwent associated meniscectomy. Most common mechanism of injury was activity of sports in 20 patients. Postoperatively at 3 months, anterior drawer’s was 1+ in 6, 29 (85.2% patients had normal range of motion; 29 (85.29% patients had 5/5 quadriceps power (MRC grading 94% of them had 5/5 power at latest followup. No significant difference between outcomes of BPTB and Hamstrings graft. Functional outcome of our study were similar to the previously published studies.

    2013-01-01

    Full Text Available Introduction: Bilateral shoulder dislocation are most commonly posterior type. These are most commonly due to seizure disorder and electrocution. Anterior shoulder dislocations occurring bilaterally without any predisposing factors are very rare. These types of injuries are due to trauma with a unique mechanism of injury. To best of our knowledge there are only few cases of similar kind are reported in literature. We hereby report a interesting case of posttraumatic, bilateral anterior dislocation of shoulder without associated fracture in a 45 old women without any predisposing pathoanatomy.Case Report: A 45-year-old women presented to casualty with sudden onset of pain and restriction of movement in both shoulders fallowing trauma. Immediately post trauma she had severe pain and restriction of both shoulders. On examination arms were abducted and externally rotated. Bilateral shoulder movements were painful and restricted . There was loss of round contour of shoulder with increased vertical diameter of axilla anteriorly. Radiological examination revealed bilateral anterior dislocation of the shoulders without any associated fractures. Closed reduction done by Milch technique after intraraticular lignocaine injection. MRI of bilateral shoulder showed no pathological lesion. Both shoulders were immobilized with a shoulder immobilizer for three weeks.Conclusion: Most of the bilateral shoulder dislocations are posterior type seen in seizure disorders. Bilateral traumatic anterior shoulder dislocations are rare and are seen as a result of unique mechanism of injury. In our case patient had a fall on her elbows causing forced extension. If diagnosed and treated promptly completely normal function of the shoulders can be restored.

  7. Anterior and posterior centers jointly regulate Bombyx embryo body segmentation.

    Science.gov (United States)

    Nakao, Hajime

    2012-11-15

    Insect embryo segmentation is largely divided into long and short germ types. In the long germ type, each segment primordium is represented on a large embryonic rudiment of the blastoderm, and segmental patterning occurs nearly simultaneously in the syncytium. In the short germ type, however, only anterior segments are represented in the small embryonic rudiment, usually located on the egg posterior, and the rest of the segments are added sequentially from the posterior growth zone in a cellular context. The long germ type is thought to have evolved from the short germ type. It is proposed that this transition, which appears to have occurred multiple times over the course of evolution, was realized through the acquisition of a localized anterior instruction center. Here, I examined the early segmentation process in the silkmoth Bombyx mori, a lepidopteran insect, in which the mechanisms of anterior-posterior (AP) axis formation have not been well analyzed. In this insect, both the long germ and short germ features have been reported. The mRNAs for two key genes involved in insect AP axis formation, orthodenticle (Bm-otd) and caudal (Bm-cad), are localized maternally in the germ anlage, where they act as anterior and posterior instruction centers, respectively. RNAi studies indicate that, while Bm-cad affects the formation of all the even skipped (Bm-eve) stripes, there is also anterior Bm-eve stripe formation activity that involves Bm-otd. Thus, there is redundancy in Bm-eve stripe formation activity that must be coordinated. Some genetic interactions, identified either experimentally or hypothetically, are also introduced, which might enable robust AP formation in this organism.

    2009-12-01

    Full Text Available Background: Tooth is the hardest tissue in human body, that can be injured because of attrition process. For old people, denture attrition process is caused by psysiological process relating with the mastication function which also supported by some bad habits such an bruxism, premature contact, and consuming habit of abrasive food. Attrition or abrasion can also be happened with patien’t dentition who does not have teeth subtutition for long time due the lost of their maxillary as well as mandibulary. The pasient will loose their vertical dimension of occlusion, injure, and the lower jaw becomes over closed which is called over closure. Purpose: This article reported the management of over closured anterior teeth due to attrition. Case: a seventy six year old woman patient came to Prosthodontic Clinic in Faculty of Dentistry, Airlangga University, to rehabilitate her upper and lower severe attrited anterior teeth and her posterior teeth. The patient has experienced of wearing acrylic removable mandibular partial denture ten years ago. Unfortunaly, the denture was uncomfortable, and she did not wear it anymore since five years ago. Case management: The severe attrition of anterior teeth with the lost of occlusal vertical dimension can be treated by improving the occlusal vertical dimension gradually. The treatment is then followed by the increasing of the height of the anterior teeth by lengthening the crown teeth of upper jaw with 12 units of span bridge and the acrylic removable partial denture of lower jaw. Conclusion: The severe attrition of anterior teeth with the lost of occlusal vertical dimension can be treated by improving the occlusal vertical dimension gradually, using long span bridge and acrylic removable partial denture.

    2013-01-01

    Full Text Available Background: Anterior cervical interbody grafts/cages combined with a plate were frequently used in multilevel discectomies/corpectomies. In order to avoid additional posterior stabilization in patients who undergo anterior reconstructive surgery, an anterior cervical transpedicular screw fixation, which offers higher stability is desirable. We investigated in this study the anatomical (morphologic characters for cervical anterior transpedicular screw fixation. Materials and Methods: Left pedicle parameters were measured on computed tomography (CT images based on 36 cervical spine CT scans from healthy subjects. The parameters included outer pedicle width (Distance from lateral to medial pedicle surface in the coronal plane, outer pedicle height (OPH (Distance from upper to lower pedicle surface in the sagittal plane, maximal pedicle axis length (MPAL, distance transverse insertion point (DIP, distance of the insertion point to the upper end plate (DIUP, pedicle sagittal transverse angle (PSTA and pedicle transverse angle (PTA at C3 to C7. Results: The values of outer pedicle width and MPAL in males were larger than in females from C3 to C7. The OPH in males was larger than in females at C3 to C6, but there was no difference at C7. The DIP and PTA were significantly greater in males than in females at C3, but there was no difference in the angle at C4-7. The PSTA was not statistically different between genders at C3, 4, 7, but this value in males was larger than females at C5, 6. The DIUP was significantly greater in males at C3, 4, 6, 7 but was non significant at C5. Conclusions: The placement of cervical anterior transpedicular screws should be individualized for each patient and based on a detailed preoperative planning.

    Objective:To demonstrate and evaluate a modified simple method about self-reduction of anterior shoulder dislocation for significance in the emergency room. Methods:TheBoss-Holzach-Matter method for self-reduction of anterior shoulder disloaction is described.Patients with an anterior shoulder dislocation were retrospectively analysed concerning age, gender, type of anterior shoulder dislocation, occurrence of associated fractures, time between injury and reduction, reduction time, and method of reduction with its respective success rate. Results:Eighty-six patients(52 men,34 women, mean age49 years) were treated fromJanuary 2010 toJune2014.The reduction time ranged between20 seconds and6 min(mean1.5 min). Subcoracoid type of shoulder dislocation was seen in72 cases(84%), subglenoid type in14 cases(16%).Associated factures were seen in20 cases, proportionally more often in subgleboid dislocations,12 at the greater tuberosity,6 at the inferior rim of the glenoid fossa and2 at both localizations.TheBoss-Holzach-Matter method was used in35 cases with a success rate of 71.5%; dieKocher method and traction/countertraction method with premedication were used in 14 cases and17 cases with success rates of64% and70%, respectively.All other cases and the failed primary attempts required hyponotic medication.All patients older than70(n=16) were not able to perform the self reducing procedure. Conclusion:The presentedBoss-Holzach-Matter method for reduction of anterior shoulder dislocation is a simple method without the need of anaesthesia, but cooperation from patients is crucial.The successful rate is comparable with other established methods.

    Full Text Available A menudo sólo se conocen estimaciones de las variables financieras. Es usual que con objeto de utilizar modelos clásicos, apreciaciones como “una tasa de entre el 5% y el 7%”, se conviertan en cantidades exactas, como puede ser el promedio entre los valores extremos. En este trabajo se propone un enfoque más flexible que permite captar la incertidumbre mediante la utilización de algunos elementos de la teoría de los conjuntos borrosos. La imprecisión presente en el capital, interés y/o cantidad de períodos se modela mediante números borrosos triangulares. Al apelar a los enfoques clásicos para evaluar expresiones algebraicas con coeficientes borrosos que hacen uso del principio de extensión y aritmética de -cortes, se definen las extensiones fuzzy de las relaciones financieras elementales. Se obtienen las versiones fuzzy del valor actual y del valor final de un capital borroso y el VAN mediante la resolución de ecuaciones con coeficientes borrosos por el método de α - cortes. Estos desarrollos se aplican a distintos casos de estudio. Por último, se muestra que no siempre es posible hallar un análogo borroso de la TIR utilizando los métodos clásicos de resolución de ecuaciones con coeficientes borrosos. Se calcula valiéndose de un nuevo concepto de solución

    Full Text Available Headed studs are nowadays the standard steel-concrete connectors because of their competitive advantages. Firstly, they provide a high degree of safety thanks to semiautomatic electric arc welding. These welds are not suitable for typical non-destructive tests. The analytical study comprises several models. The first vibration modes have been obtained. The experimental research has developed first the measurement of the natural frequencies of 28 headed-studs in the sonic range. Then they have been tested by non-destructive and destructive tests. Finally theirs tests have been compared with their respective frequency measurements. A clear relationship between the measured frequencies and the lack of penetration of the welds has been established, that confirms the analytical prediction of this effect of the internal weld imperfections. Therefore, the feasibility of simple and absolutely non-destructive tests of welded studs by in site measurement of natural frequencies in the sonic range has been clearly established in this work.

    Los pernos conectores aportan múltiples ventajas de uso, entre las que se encuentra el elevado margen de seguridad que ofrecen sus soldaduras ejecutadas mediante arco eléctrico. Estas soldaduras, aunque ampliamente fiables, son difícilmente comprobadas mediante ensayos no destructivos. El presente estudio plantea la inspección de soldaduras de pernos conectores mediante su espectro acústico. Analíticamente, la investigación se ha centrado en el cálculo de los primeros modos propios de vibración. Experimentalmente se han medido las frecuencias propias de resonancia de 28 pernos, en los que posteriormente se han llevado a cabo ensayos tanto no destructivos como destructivos. Se ha obtenido, tanto teórica como experimentalmente, una relación entre la frecuencia de vibración de los pernos conectores y la calidad de la soldadura. Por ello se verifica la posibilidad de inspección de estas

    Full Text Available Introduction The most frequent procedure in treatment of acute or chronic anterior cruciate ligament (ACL rupture is the so called bone-tendon-bone reconstruction. A transverse dislocated patella fracture is a rare complication of this procedure with an incidence of 0.23%-2.3%. In a five year period, (1998-2002, 407 arthroscopic reconstructions of the anterior cruciate ligaments were done at our Clinic, and there was only one case of patella fracture. Case report An 18-year-old female patient, a handball player, suffered an acute rupture of anterior cruciate ligament of the left knee, so arthroscopic bone-tendon-bone reconstruction of the anterior cruciate ligament was performed. After adequate skin incision, a bone graft was taken from the patella and upper part of trapezoid tibia, which was 25 mm long, 10 mm wide and 5 mm thick, together with a part of patellar ligament. After the remains of the anterior cruciate ligament had been arthroscopically removed, tunnels were made in tibia and femur and a graft was inserted and fixed with two metal interference screws. Knee stability was tested, and drainage was put in the knee joint. The wound was closed by layers. The quadriceps exercises and passive knee movements started immediately. Full range of movements was accomplished six weeks later when the patient started to walk with full weight-bearing on her operated leg. Three weeks later, (nine weeks after the operation, the patient has accidentally lost her balance and fell. A transverse, dislocated fracture of the left patella was diagnosed and osteosynthesis of the fractured patella with two Kirschner wires and a metallic loop was performed. Postoperatively, full range of movement was allowed. Six months later, the patient felt no pain, there was no swelling, full range of knee movement was achieved, while the Lachman Test was identical in both knees and the pivot shift test was negative. Discussion Fracture of patella after ACL reconstruction is

This avoids the need to subject columns to high torsional stresses. This system, by prestressing, induces internal moments which compensate the torsional moment. This reduces, or eliminates, under certain loading cases, the angular deflection due to torsion couples. Primarily, a study is carried out on this type torsion — with the example of a simple hollow beam, in corbel,En este artículo se estudia la posibilidad de transferir momentos al firme mediante la resistencia torsional de una viga, evitándose así soluciones de pilas o pilares solicitados fuertemente por torsión y creando, mediante pretensado, momentos internos que contrarresten directamente al momento torsor actuante, con lo cual se reduce e incluso se elimina, para ciertos casos de carga, el giro de la sección debido al par torsor.

    Bordetella pertussis synthesis a variety of virulence factors including a calmodulin-dependent adenylate cyclase (AC) toxin. Treatment of anterior pituitary cells with this AC toxin resulted in an increase in cellular cAMP levels that was associated with accelerated exocytosis of growth hormone (GH), prolactin, adrenocorticotropic hormone (ACTH), and luteinizing hormone (LH). The kinetics of release of these hormones, however, were markedly different; GH and prolactin were rapidly released, while LH and ACTH secretion was more gradually elevated. Neither dopamine agonists nor somatostatin changes the ability of AC toxin to generate cAMP (up to 2 h). Low concentrations of AC toxin amplified the secretory response to hypophysiotrophic hormones. The authors conclude that bacterial AC toxin can rapidly elevate cAMP levels in anterior pituitary cells and that it is the response that explains the subsequent acceleration of hormone release.

    Severe vertical ridge deficiency in the anterior maxilla represents one of the most challenging scenarios in bone regeneration. Under ideal circumstances, guided bone regeneration in combination with soft tissue management has shown predictable esthetic and functional outcomes. Success largely relies on primary wound closure during and after the surgical procedure. Surgical sites present different challenges that need to be considered when designing the flap. The goal of this article is to propose a classification of flap designs that considers vestibular depth and scar formation around the periosteum when performing vertical ridge augmentation in the atrophic anterior maxilla. The four clinical conditions proposed under this classification are (1) shallow vestibule with healthy periosteum, (2) deep vestibule with healthy periosteum, (3) shallow vestibule with scarred periosteum, and (4) deep vestibule with scarred periosteum. The classification will allow clinicians to achieve tension-free closure and more predictable vertical bone gain.

    2001-07-01

    Anterosuperior instability of the shoulder may occur from a variety of pathologic lesions. We describe a specific entity, the SLAC (superior labrum, anterior cuff) lesion that involves an association of anterior-superior labral tear with a partial supraspinatus tear. We retrospectively isolated a group of 40 patients with this lesion. The presenting complaints, physical examination findings, surgical findings, and results were isolated. Overhead activities were the most common etiology; load and shift instability testing and whipple rotator cuff testing were the most common physical examination findings. Surgical repair was successful in 37 of the 40 patients. The SLAC lesion is a definable clinical entity with predictable history, examination, surgical pathology, and satisfactory results from surgery.

  8. Effect of bone loss in anterior shoulder instability

    Garcia, Grant H; Liu, Joseph N; Dines, David M; Dines, Joshua S

    2015-01-01

    Anterior shoulder instability with bone loss can be a difficult problem to treat. It usually involves a component of either glenoid deficiency or a Hill-Sachs lesion. Recent data shows that soft tissue procedures alone are typically not adequate to provide stability to the shoulder. As such, numerous surgical procedures have been described to directly address these bony deficits. For glenoid defects, coracoid transfer and iliac crest bone block procedures are popular and effective. For humeral head defects, both remplissage and osteochondral allografts have decreased the rates of recurrent instability. Our review provides an overview of current literature addressing these treatment options and others for addressing bone loss complicating anterior glenohumeral instability. PMID:26085984

  9. Dilemmas in Treatment of Recurrent Recalcitrant Dental Anterior Open Bite.

    2016-01-01

    An anterior open bite is one of the most difficult occlusal abnormalities to treat. Quite often this aberration entails dental component and/or skeletal component. The skeletal open bite will require intrusion of the posterior sextants with the assistance of bite blocks, temporary anchorage devices, high pull headgear, and as a last resort - orthognathic surgery. The orthodontic treatment should be augmented with the orofacial myofunctional therapy. In this article, the author describes 3 different variations of treatment of the dental anterior open bite, first on acrylic models, and then on the actual patients. Consideration should be given to patients with a 'short upper lip," and in this case, surgical correction should be entertained.

  10. Anterior cervical fusion and Caspar plate stabilization for cervical trauma.

    Caspar, W; Barbier, D D; Klara, P M

    1989-10-01

    A technique for anterior cervical iliac graft fusion with standardized, commercially available screw and plate fixation (Caspar plating) has been developed. The step-by-step procedure, as well as the instruments designed to facilitate the procedure, are described in this report. Sixty cases of cervical trauma (fractures, subluxations, ligamentous instability, or a combination of these problems) were treated with Caspar plating. All patients obtained fusion, and stability was achieved immediately after surgery without external stabilization. No unusual surgical complications occurred, and the most dreaded complication of dural penetration by drilling or screw placement was not observed. This report details the neurological presentation, anatomical lesions, surgical therapy, and outcome of these patients. Caspar plating combines the advantage of an anterior surgical approach with immediate postoperative stabilization without external stabilization. This advantage persists even in the presence of posterior ligamentous instability. The technique is an important addition to the surgical treatment of cervical trauma.

    Full Text Available Genetic diseases are congenital or acquired hereditary diseases that result from structural/functional disorders of the human genome. Today, the genetic factors that play a role in many diseases are being highlighted with the rapid progress in the field of genetics science. It becomes increasingly important that physicians from all disciplines have knowledge about the basic principles of genetics, patterns of inheritance, etc., so that they can follow the new developments. In genetic eye diseases, ophthalmologists should know the basic clinical and recently rapidly developing genetic characteristics of these diseases in order to properly approach the diagnosis and treatment and to provide genetic counseling. In this paper, anterior segment eye diseases of genetic origin are reviewed, and aniridia, anterior segment dysgenesis, glaucoma, corneal dystrophies, cataract, ectopia lentis, myopia, and other refractive errors are covered.

    Full Text Available The important role of the tooth size information is in making diagnosis and treatment plan of the cases with malocclusion. A lot of studies have been done in this aspect such as about tooth size with its variation, and also the ratio of maxillary to mandibular tooth size. The most famous tooth size analysis is Bolton analysis with his anterior ratio and overall ratio. Because the accordance of those ratio is not found in all orthodontic cases, some studies (Korbitz, Neff, Moyers and Steadman tried to relate the anterior ratio with the amount of overjet and overbite in orthodontic treatment. Those relationship was found strong, but there are also other analysis that should be considered in treating orthodontic cases.

    Full Text Available A luxação glenoumeral anterior bilateral é uma ocorrência rara. Apresentamos um caso de luxação glenoumeral anterior bilateral com origem após uma queda da própria altura. O interesse desta publicação reside no fato de se tratar de uma raridade clínica com poucos casos descritos na literatura. Paciente do sexo feminino com 89 anos recorre ao serviço de urgência (SU após queda referindo dor intensa e incapacidade de mobilização de ambos os ombros. Ao exame objetivo apresentava sinais clínicos suspeitos de luxação glenoumeral anterior bilateral confirmados por radiografia. Ambas as luxações foram reduzidas no SU pela técnica de Milch modificada, com sucesso. Quando existe uma força simétrica e síncrona sobre os ombros e estes se apresentarem dolorosos e com limite funcional significativo, a suspeita de luxação glenoumeral bilateral, embora rara, é um diagnóstico diferencial a ter em conta.Bilateral anterior glenohumeral dislocation is a rare occurrence. We present a case of bilateral anterior glenohumeral dislocation caused by a fall. The interest in publishing this case is that this is a clinical rarity with few cases reported in the literature. An 89-year-old female patient was brought to the emergency department after a fall, complaining of intense pain in both shoulders and inability to move them. Objective examination showed clinical signs giving the suspicion of bilateral anterior glenohumeral dislocation, which was confirmed by x-ray imaging. Both dislocations were successfully reduced in the emergency department using the modified Milch technique. When a synchronous and symmetrical force has acted on both shoulders and these are painful with significant functional limitation, the suspicion of bilateral glenohumeral dislocation is a differential diagnosis to be considered, even though it is rare.

    Full Text Available Septic arthritis of the knee is a rare complication after arthroscopic anterior cruciate ligament reconstruction, and the most appropriate treatment is unclear. All case series reported so far have been retrospective, and case numbers of septic arthritis have ranged from 4 to 11. From a consecutive case series of 1,283 patients who underwent arthroscopic anterior cruciate ligament reconstruction between January 1997 and May 2008, we report on 3 patients (0.23% with post-operative septic arthritis. All patients had acute infection (≤ 2 weeks, bacterial cultures showed Staphylococcus species in 2 patients, while the bacterial culture was negative in the third. All of them underwent immediate arthroscopic debridement and lavage with continuous irrigation, as well as antibiotic treatment. The results were evaluated with physical and radiographic examination, functional testing, KT-2000, Lysholm and Tegner scales. The infection was successfully eradicated without further surgical treatment and the ligament graft was retained in all patients. Follow-up, at an average of 33 months, revealed that the patients had full symmetric knee range of motion and no effusion. The average Lysholm score was 91 points. In the patient with a lower subjective score, radiographs demonstrated patellofemoral joint-space narrowing, which is most probably in correlation with his anterior knee pain problems and lower activity level. The 134 N KT-2000 arthrometer side-to-side differences averaged 13 mm. Their performance in the single-legged hop test gave excellent results. The goals of treatment for septic arthritis after anterior cruciate ligament reconstruction are, primarily, to protect the articular cartilage and, secondly, to protect the graft. Through early diagnosis and prompt treatment, the infection can be successfully eradicated, with stability of the knee and full range of motion achieved.

  19. Anterior knee pain: an update of physical therapy.

    Science.gov (United States)

    Werner, Suzanne

    2014-10-01

    Anterior knee pain is one of the most common knee problems in physically active individuals. The reason for anterior knee pain has been suggested to be multifactorial with patella abnormalities or extensor mechanism disorder leading to patellar malalignment during flexion and extension of the knee joint. Some patients complain mostly of non-specific knee pain, while others report patellar instability problems. The patients present with a variety of symptoms and clinical findings, meaning that a thorough clinical examination is the key for optimal treatment. Weakness of the quadriceps muscle, especially during eccentric contractions, is usually present in the majority of anterior knee pain patients. However, irrespective of whether pain or instability is the major problem, hypotrophy and reduced activity of the vastus medialis are often found, which result in an imbalance between vastus medialis and vastus lateralis. This imbalance needs to be corrected before quadriceps exercises are started. The non-operative rehabilitation protocol should be divided into different phases based on the patient's progress. The goal of the first phase is to reduce pain and swelling, improve the balance between vastus medialis and vastus lateralis, restore normal gait, and decrease loading of the patello-femoral joint. The second phase should include improvement of postural control and coordination of the lower extremity, increase of quadriceps strength and when needed hip muscle strength, and restore good knee function. The patient should be encouraged to return to or to start with a suitable regular physical exercise. Therefore, the third phase should include functional exercises. Towards the end of the treatment, single-leg functional tests and functional knee scores should be used for evaluating clinical outcome. A non-operative treatment of patients with anterior knee pain should be tried for at least 3 months before considering other treatment options.

    Full Text Available Objectives: To report the intraoperative and postoperative follow-up complications and management of these in deep anterior lamellar keratoplasty (DALK surgery. Materials and Methods: Two hundred eighty-four eyes of 252 patients followed up in our cornea clinic who underwent DALK using Anwar’s big-bubble technique with healthy Descemet’s membrane and endothelium were included in this study. Intraoperative and postoperative complications as well as the management and treatment of these complications were evaluated. Results: Big bubble was created in 220 (77.5% eyes of 284 eyes, and lamellar dissection was performed in 64 (22.5% eyes. Perforation occurred during trephination in 4 eyes, and the procedure was accomplished by penetrating keratoplasty (PK. Intraoperative microperforation occurred in 44 eyes. Perforation enlarged in 4 eyes and PK was performed. Operation was continued in 40 eyes with air injection into the anterior chamber. In postopertive follow-up period, double anterior chamber (DAC occurred in 32 of 40 eyes. DAC spontaneously regressed in 8 eyes, and air was given into the anterior chamber with a second surgical intervention in 24 eyes. DAC improved in 20 eyes. Four eyes underwent PK. Fungal keratitis evolved at the interface in one eye, because of no healing during the follow-up period, this eye underwent PK under antifungal therapy. Eyes with interface haze and Descemet’s membrane folds were followed. Conclusion: DALK is a difficult technique with a steep learning curve. In addition to the complications seen in PK, specific complications can occur in lamellar surgery. (Turk J Ophthalmol 2014; 44: 337-40

  8. 3D spectral imaging system for anterior chamber metrology

    Anderson, Trevor; Segref, Armin; Frisken, Grant; Frisken, Steven

    2015-03-01

    Accurate metrology of the anterior chamber of the eye is useful for a number of diagnostic and clinical applications. In particular, accurate corneal topography and corneal thickness data is desirable for fitting contact lenses, screening for diseases and monitoring corneal changes. Anterior OCT systems can be used to measure anterior chamber surfaces, however accurate curvature measurements for single point scanning systems are known to be very sensitive to patient movement. To overcome this problem we have developed a parallel 3D spectral metrology system that captures simultaneous A-scans on a 2D lateral grid. This approach enables estimates of the elevation and curvature of anterior and posterior corneal surfaces that are robust to sample movement. Furthermore, multiple simultaneous surface measurements greatly improve the ability to register consecutive frames and enable aggregate measurements over a finer lateral grid. A key element of our approach has been to exploit standard low cost optical components including lenslet arrays and a 2D sensor to provide a path towards low cost implementation. We demonstrate first prototypes based on 6 Mpixel sensor using a 250 μm pitch lenslet array with 300 sample beams to achieve an RMS elevation accuracy of 1μm with 95 dB sensitivity and a 7.0 mm range. Initial tests on Porcine eyes, model eyes and calibration spheres demonstrate the validity of the concept. With the next iteration of designs we expect to be able to achieve over 1000 simultaneous A-scans in excess of 75 frames per second.

  16. Activation of anterior insula during self-reflection.

    Directory of Open Access Journals (Sweden)

    Gemma Modinos

    Full Text Available BACKGROUND: Functional neuroimaging studies have suggested activation of midline frontoparietal brain regions to be at the core of self-related processes. However, although some studies reported involvement of the insula, little attention has been paid to this region as forming part of the "self"-network. METHODOLOGY/PRINCIPAL FINDINGS: Using functional magnetic resonance imaging (fMRI, we aimed at replicating and extending previous studies by scanning subjects whilst reflecting upon their own personal qualities as compared to those of an acquaintance. A third condition with statements about general knowledge was used to control for attention, semantic processing and decision making processes. The results showed a significant effect of task in brain activity, consistent with previous findings, by which both person conditions recruited a common set of medial prefrontal and posterior regions, yet significant differences between self and other were found in the medial prefrontal cortex (MPFC and the anterior cingulate cortex (ACC. Notably, significant neural activation in the left anterior insula was observed as uniquely associated with self-reflection. CONCLUSIONS/SIGNIFICANCE: The results provide further evidence for the specific recruitment of anterior MPFC and ACC regions for self-related processing, and highlight a role for the insula in self-reflection. As the insula is closely connected with ascending internal body signals, this may indicate that the accumulation of changes in affective states that might be implied in self-processing may contribute to our sense of self.

  17. LOWER EXTREMITY MALALIGNMENTS AND ANTERIOR CRUCIATE LIGAMENT INJURY HISTORY

    Rebecca A. Braham

    2004-12-01

    Full Text Available To identify if lower extremity malalignments were associated with increased propensity of a history of anterior cruciate ligament (ACL ruptures in males and females using a case control design. Twenty subjects (10 males, 10 females had a history of ACL injury and twenty (10 males, 10 females had no history of ACL injury. Subjects were assessed for navicular drop, quadriceps angle, pelvic tilt, hip internal and external rotation range of motion, and true and apparent leg length discrepancies. Statistical analysis was performed to identify differences in these measures in regard to injury history and gender, and to identify if any of these measures were predictive of ACL injury history. Increased navicular drop and anterior pelvic tilt were found to be statistically significant predictors of ACL injury history regardless of gender. Limbs that had previously suffered ACL ruptures were found to have increased navicular drop and anterior pelvic tilt compared to uninjured limbs. Based on the results of this retrospective study, the lower extremity malalignments examined do not appear to predispose females to tearing their ACLs more than males.

This study reports the case of a female patient with acute unilateral anterior uveitis caused by alexandrite laser-assisted hair removal of the eyebrows. We report a 38-year-old female who presented with unilateral eye pain, redness, and photophobia after receiving alexandrite (755 nm laser epilation of both eyebrows. Best corrected visual acuity was 20/20 in both eyes. Right eye examination was normal. Left eye examination showed conjunctival injection and 2+/3+ cells in the anterior chamber. Intraocular pressure and fundus examination were normal. Topical steroids and cycloplegic drops were prescribed for 3 weeks. At the end of the 3-week follow-up, best corrected visual acuity was 20/20, and intraocular pressure and fundus examination were normal in both eyes. The left eye was white, and the anterior chamber was clear. The patient continues to be monitored. In conclusion, without adequate protective eyewear, laser hair removal of the eyebrows with alexandrite laser can lead to ocular damage.

    Full Text Available Objective. To report a novel tympanoplasty modification for anterior tympanic membrane perforation closure. Materials and Methods. A prospective study on 13 patients who underwent inferior tympanoplasty between December 2008 and May 2011 was carried out. In our technique, an inferior rather than a posterior flap is raised and the graft is laid from the inferior direction to obtain better access to the anterior part of the tympanic membrane perforation and provide better support. Results. A total of 13 patients underwent the novel inferior tympanoplasty technique with a mean age of 33 years. Six patients had undergone tympanoplasties and/or mastoidectomies in the past, 3 in the contralateral ear. A marginal perforation was observed in 3 cases, total perforation in 2 and subtotal in 1 case. The mean preoperative pure-tone average was 40.4 dB (10 to 90 dB, compared to 26.5 dB (10 to 55 dB postoperatively. All perforations were found to be closed but one (92.3% success rate. Conclusions. The inferior tympanoplasty technique provides a favorable outcome in terms of tympanic membrane closure and hearing improvement for anterior perforations, even in difficult and complex cases. It is based on a well-known technique and is easy to implement.

    This is a case of nontraumatic shoulder pain initially diagnosed on x-ray as an anterior dislocation. The patient was on anticoagulants and, in actuality, had severe hemarthrosis that caused the subluxation. Attempts to reduce the dislocation in this situation might have resulted in worsening of the intra-articular bleed. There has been only 1 similar reported case in the European Journal of Emergency Medicine in 2013 of a 53-year-old woman who was thought to have a nontraumatic anterior shoulder dislocation, and attempts were unsuccessful at reduction. Definitive therapy involved hemarthrosis aspiration. Others have reported spontaneous hemarthrosis due to anticoagulants; however, only 1 has reported an initial mistaken joint dislocation diagnosis. Nontraumatic hemarthrosis do occur in patients on anticoagulant therapy, and it is important to recognize that this can be misdiagnosed as a joint dislocation requiring reduction. In a patient who is on anticoagulants presenting with nontraumatic joint pain and anterior shoulder or possibly other dislocations on plain radiographs, it is pertinent to consider hemarthrosis.

    Full Text Available Abstract Background Zoledronic acid is very widely used in patients with metastatic bone disease and osteoporosis. Only one case of bilateral uveitis was recently reported related to its use. Case presentation We report the first case of severe unilateral anterior uveitis in a patient with breast cancer and an intraocular lens. Following zoledronic acid infusion, the patient developed severe and dramatic right eye pain with decreased visual acuity within 24 hours and was found to have a fibrinous anterior uveitis of moderate severity The patient was treated with topical prednisone and atropine eyedrops and recovered slowly over several months. Conclusion Internists, oncologists, endocrinologists, and ophtalmologists should be aware of uveitis as a possible complication of zoledronic acid therapy. Patients should be instructed to report immediately to their physicians and treatment with topical prednisone and atropine eyedrops should be instituted immediately at the onset of symptoms. This report documents anterior uveitis as a complication of zoledronic acid therapy. This reaction could be an idiosyncratic one but further research may shed more light on the etiology.

    Despite the importance of breaches of taste identity expectation for survival, its neural correlate is unknown. We used fMRI in 16 women to examine brain response to expected and unexpected receipt of sweet taste and tasteless/odorless solutions. During expected trials (70%), subjects heard "sweet" or "tasteless" and received the liquid indicated by the cue. During unexpected trials (30%), subjects heard sweet but received tasteless or they heard tasteless but received sweet. After delivery, subjects indicated stimulus identity by pressing a button. Reaction time was faster and more accurate after valid cuing, indicating that the cues altered expectancy as intended. Tasting unexpected versus expected stimuli resulted in greater deactivation in fusiform gyri, possibly reflecting greater suppression of visual object regions when orienting to, and identifying, an unexpected taste. Significantly greater activation to unexpected versus expected stimuli occurred in areas related to taste (thalamus, anterior insula), reward [ventral striatum (VS), orbitofrontal cortex], and attention [anterior cingulate cortex, inferior frontal gyrus, intraparietal sulcus (IPS)]. We also observed an interaction between stimulus and expectation in the anterior insula (primary taste cortex). Here response was greater for unexpected versus expected sweet compared with unexpected versus expected tasteless, indicating that this region is preferentially sensitive to breaches of taste expectation. Connectivity analyses confirmed that expectation enhanced network interactions, with IPS and VS influencing insular responses. We conclude that unexpected oral stimulation results in suppression of visual cortex and upregulation of sensory, attention, and reward regions to support orientation, identification, and learning about salient stimuli.

Anterior uveitis may be caused by a variety of etiologies, including infectious, noninfectious, and masquerade diseases. The short-term and long-term treatment of uveitis should include the evaluation of location, duration, pathology, and laterality, in addition to presenting signs and symptoms of the disease. A complete review of systems, thorough examination, and laboratory testing, may assist the practitioner in narrowing the list of possible causes for the uveitis. This is imperative as once a list of diagnoses has been made, a targeted approach to treatment can be pursued. Keywords: anterior uveitis, iritis, inflammation

    Social pain after exclusion by others activates brain regions also involved in physical pain. Here we evaluated whether monetary reward could compensate for the negative feeling of social pain in the brain. To address this question we used the unique technique of intracranial electroencephalography in subjects with drug resistant epilepsy. Specifically, we recorded theta activity from intracranial electrodes implanted in the insular cortex while subjects experienced conditions of social inclusion and exclusion associated with monetary gain and loss. Our study confirmed that theta rhythm in the insular cortex is the neural signature of social exclusion. We found that while monetary gain suppresses the effect of social pain in the anterior insula, there is no such effect in the posterior insula. These results imply that the anterior insula can use secondary reward signals to compensate for the negative feeling of social pain. Hence, here we propose that the anterior insula plays a pivotal role in integrating contingencies to update social pain feelings. Finally, the possibility to modulate the theta rhythm through the reward system might open new avenues of research for treating pathologies related to social exclusion.

    The diagnosis and management of chronic anterior knee pain in the active individual can be frustrating for both the patient and physician. Pain may be a result of a single traumatic event or, more commonly, repetitive overuse. "Anterior knee pain," "patellofemoral pain syndrome," and "chondromalacia" are terms that are often used interchangeably to describe multiple conditions that occur in the same anatomic region but that can have significantly different etiologies. Potential pain sources include connective or soft tissue irritation, intra-articular cartilage damage, mechanical irritation, nerve-mediated abnormalities, systemic conditions, or psychosocial issues. Patients with anterior knee pain often report pain during weightbearing activities that involve significant knee flexion, such as squatting, running, jumping, and walking up stairs. A detailed history and thorough physical examination can improve the differential diagnosis. Plain radiographs (anteroposterior, anteroposterior flexion, lateral, and axial views) can be ordered in severe or recalcitrant cases. Treatment is typically nonoperative and includes activity modification, nonsteroidal anti-inflammatory drugs, supervised physical therapy, orthotics, and footwear adjustment. Patients should be informed that it may take several months for symptoms to resolve. It is important for patients to be aware of and avoid aggravating activities that can cause symptom recurrence. Patients who are unresponsive to conservative treatment, or those who have an underlying systemic condition, should be referred to an orthopedic surgeon or an appropriate medical specialist.

    Full Text Available Background. Chondrosarcomas represent approximately 30% of primary malignant bone tumors, the most frequent of which is on anterior thoracic wall. Case report. We presented a case of 50-year-old man suffering from a slowgrowing, painless giant chondrosarcoma of the anterior chest wall. A wide resection was performed to excise the tumor including attached skin, right breast, ribs, sternum, soft tissues and parietal pleura. Mediastinum was not affected by the tumor. After resecting a 26 × 20 × 22 cm segment, the chest wall defect was reconstructed with a Marlex mesh and extensive latissimus dorsi myocutaneous flap pedicled on the right thoracodorsal vessels. Histopatology diagnosis was chondrosarcoma G 2−3. The mechanics of ventilation was not altered and respiratory function was normal from the immediate postoperative period. Three years after the operation postoperative results showed no local recurrence and excellent functional and aesthetic results were evident. Respiratory function remained unaltered. Conclusion. According to the results it can be concluded that the use of Marlex mash and myocutaneous flap is good method for stabilization of the chest wall and enough to avoid paradoxical respiratory movements in managing giant chondrosarcoma of the anterior chest wall.

    Planning spatial paths through our environment is an important part of everyday life and is supported by a neural system including the hippocampus and prefrontal cortex. Here we investigated the precise functional roles of the components of this system in humans by using fMRI as participants performed a simple goal-directed route-planning task. Participants had to choose the shorter of two routes to a goal in a visual scene that might contain a barrier blocking the most direct route, requiring a detour, or might be obscured by a curtain, requiring memory for the scene. The participant's start position was varied to parametrically manipulate their proximity to the goal and the difference in length of the two routes. Activity in medial prefrontal cortex, precuneus, and left posterior parietal cortex was associated with detour planning, regardless of difficulty, whereas activity in parahippocampal gyrus was associated with remembering the spatial layout of the visual scene. Activity in bilateral anterior hippocampal formation showed a strong increase the closer the start position was to the goal, together with medial prefrontal, medial and posterior parietal cortices. Our results are consistent with computational models in which goal proximity is used to guide subsequent navigation and with the association of anterior hippocampal areas with nonspatial functions such as arousal and reward expectancy. They illustrate how spatial and nonspatial functions combine within the anterior hippocampus, and how these functions interact with parahippocampal, parietal, and prefrontal areas in decision making and mnemonic function.

    Anterior odontoid screw fixation has been proved to be effective but technically challenging because the difficult approach is associated with high risks of screw malposition and damage to surrounding vital structures. Navigation techniques are therefore increasingly being used to improve safety and accuracy. However, no robot-assisted odontoid screw fixation has yet been reported. We here report a 61-year-old woman with a type II dens fracture on whom anterior odontoid screw fixation was performed under the guidance of a newly developed robotic system (TiRobot, co-designed by Beijing Jishuitan Hospital and TINAVI Medical Technologies). One odontoid screw was safely and accurately placed, the calculated deviation between the planned and actual positions being 0.9 mm. No intraoperative complications were identified and the patient was discharged on Day 5. Follow-up studies after 2 weeks showed good clinical and radiological results. We believe this is the first reported case of robot-assisted anterior odontoid screw fixation. We consider that complicated procedures can become feasible, safe and accurate using TiRobot systems.

    Full Text Available Introduction: Degenerative changes of the cervical spine are more common in elderly, but anterior cervical osteophytes that cause problems in swallowing are rare. The most common cause of this problem is DISH disease (diffuse idiopathic skeletal hyperostosis. Trauma is also suggested as a potential cause in osteophyte formation. Case Report: We report a rare case of anterior cervical osteophyte with problems in swallowing that was caused by cervical spine trauma in a car accident 4 years ago, treated with a cervical collar. Dysphagia was the initial symptom of the disease. Barium swallowing showed a large cervical osteophyte at the C3-C4 level with compression effect on the esophagus. X-ray, CT scan and MRI of the cervical spine confirmed the osteophyte and its correlation with the esophagus. Endoscopic study of esophagus and stomach also ruled out other disorders. Surgical osteophytectomy was performed. Conclusion: Up to now, only two cases of post-traumatic anterior cervical osteophyte have been cited in the literature. In this report, we introduce an unusual case of dysphagia caused by cervical spine trauma.

  10. How do mammillary body inputs contribute to anterior thalamic function?

    2015-01-01

    It has long been assumed that the main function of the mammillary bodies is to provide a relay for indirect hippocampal inputs to the anterior thalamic nuclei. Such models afford the mammillary bodies no independent role in memory and overlook the importance of their other, non-hippocampal, inputs. This review focuses on recent advances that herald a new understanding of the importance of the mammillary bodies, and their inputs from the limbic midbrain, for anterior thalamic function. It has become apparent that the mammillary bodies’ contribution to memory is not dependent on afferents from the subicular complex. Rather, the ventral tegmental nucleus of Gudden is a vital source of inputs that support memory processes within the medial mammillary bodies. In parallel, the lateral mammillary bodies, via their connections with the dorsal tegmental nucleus of Gudden, are critical for generating head-direction signals. These two parallel, but distinct, information streams converge on the anterior thalamic nuclei and support different aspects of spatial memory. PMID:25107491

    Background This study aimed to evaluate the flexural strength and microhardness of three different anterior composites after 10 000 thermocycles. Material and Methods The mechanical properties of a nano-fill composite (Filtek Ultimate Universal Restorative (FUR) (Enamel)), a nano-hybrid composite (Clearfil Majesty ES2 (ES2) (Enamel)), and a micro-hybrid composite (G Aenial Anterior (GAA)) were investigated in this study. For the microhardness test, 8-mm diameter and 2-mm thickness composite discs were used (n = 10), and for the flexural strength test, 25x2x2 mm bar-shaped specimens were prepared (n = 13). The specimens were tested at 24 h and after 10 000 thermocycles. Data were analyzed using two-way analysis of variance and the post-hoc Tukey test (p .05). Pearson correlation analysis revealed that there was a negative relationship between the mean hardness and flexural strength values (correlation coefficient = -0.367, p = .043). After 10 000 thermocycles, microhardness values of each material and flexural strength of ES2 and GAA decreased significantly according to 24 h. Conclusions The nano-fill composite FUR displayed significantly higher microhardness values. However, each resin composite was statistically similar for flexural strength values. Ten thousand thermocycles significantly affected microhardness and flexural strength. Key words:Flexural strength, microhardness, anterior composites. PMID:28298986

    Full Text Available The biologic width (BW includes attached epithelial cells and connective tissue attachment complex being very important in the periodontal health during prosthetic treatments as invading this zone can cause bone resorption and gingival recession. The present study investigated biologic width values in the normal periodontium in anterior and posterior teeth. 30 patients that referred from restorative department to periodontics department of Tehran University of medical sciences who need crown lengthening procedure on their teeth with no history of orthodontic, prosthodontic and periodontal treatment were randomly enrolled in this cross-sectional trial. Sulcus depths (SD as well as the distance between free gingival margin and the bone crest (FB of anterior and posterior teeth were measured by UNC-15 probe and compared. periodontium thickness was also assessed. The data were subjected to Student t test. Mean BW in the 43 anterior and 47 posterior teeth was measured and not significantly different (1.4651±0.39 mm vs. 1.6312±0.49 mm was observed; however, BW was significantly more in the teeth with thick periodontium compared to those with thin periodontium (1.703±0.5 vs. 1.408±0.35; P=0.002. BW not only is different in individuals but also could be dissimilar in different teeth and should be calculated independently prior to restorative treatments.

    Australopithecus anamensis is the earliest known species of the Australopithecus-human clade and is the likely ancestor of Australopithecus afarensis. Investigating possible selective pressures underlying these changes is key to understanding the patterns of selection shaping the origins and early evolution of the Australopithecus-human clade. During the course of the Au. anamensis-afarensis lineage, significant changes appear to occur particularly in the anterior dentition, but also in jaw structure and molar form, suggesting selection for altered diet and/or food processing. Specifically, canine tooth crown height does not change, but maxillary canines and P(3)s become shorter mesiodistally, canine tooth crowns become more symmetrical in profile and P(3)s less unicuspid. Canine roots diminish in size and dimorphism, especially relative to the size of the postcanine teeth. Molar crowns become higher. Tooth rows become more divergent and symphyseal form changes. Dietary change involving anterior dental use is also suggested by less intense anterior tooth wear in Au. afarensis. These dental changes signal selection for altered dietary behaviour and explain some differences in craniofacial form between these taxa. These data identify Au. anamensis not just as a more primitive version of Au. afarensis, but as a dynamic member of an evolving lineage leading to Au. afarensis, and raise intriguing questions about what other evolutionary changes occurred during the early evolution of the Australopithecus-human clade, and what characterized the origins of the group.

    Full Text Available The incidence of impacted tooth in adolescent is usually found by oral surgeon or orthodontist during their sequence of treatments. The maxillary anterior teeth, especially canine and third lower molar are the most common impacted teeth found as the result of their eruption disturbances. The surgical technique principle is to facilitate the impacted tooth, so that it can be erupted by creating a window and take the bone obstructed surrounding the tooth crown surgically and afterward it is orthodontically tracted. In a case of third molar germ which is predicted to be impacted in mesio version position, germinectomy is preferred to prevent anterior mechanical drive during its development which may cause mal-alignment of the mandibular teeth. Germinectomy which is usually easier than odontectomy, the germ position, and less complication after the surgical intervention are three factors that should be considered in making decision.

    Background Anterior mediastinal masses include a wide variety of diseases from benign lesions to extremely malignant tumors. Management strategies are highly diverse and depend strongly on the histological diagnosis as well as the extent of the disease. We reported a prospective study comparing the usefulness of core needle biopsy and mini-mediastinotomy under local anesthesia for histological diagnosis in anterior mediastinal masses.Methods A total of 40 patients with masses of unknown histology and located either at or near the anterior mediastinum received biopsy prior to treatment. The diagnostic methods were core needle biopsy in 28 patients and biopsy through mini-mediastinotomy under local anesthesia in 15 patients (including 3 patients for whom core needle biopsy failed to yield a definite diagnosis).Results Histological diagnosis was achieved in 18 of the 28 patients receiving core needle biopsy. Of them, all 4 patients with pleural fibromas and 9 of the 12 patients (75%) with pulmonary mass were diagnosed definitively. In the remaining 12 patients with mediastinal mass, histological diagnosis was achieved in only 5 patients (41.7%). In contrast,biopsy through a mini-mediastinotomy failed in only 3 patients. In the remaining 12 patients with huge mediastinal masses, who underwent mini-mediastinotomy, a definitive histological diagnosis was reached by pathological and/or immunohistochemical study (diagnostic yield 85.7% in 12 of 14 cases of mediastinal mass, P=0.038 vs core needle biopsy). For the 9 patients with thymic epithelial tumors, the diagnostic yield was 40% (2 in 5 cases) for core needle biopsy and 83.3% (5 in 6 cases) for mini-mediastinotomy. There was no morbidity in patients receiving mini-mediastinotomy. In the 30 patients with biopsy-proven histological diagnosis, the results contributed to therapeutic decision making in 25 cases (83.3%).Conclusions Core needle biopsy is effective in the diagnosis of pulmonary and pleural diseases.

    Full Text Available O objetivo desta pesquisa foi avaliar a corrosão de parafusos auto-rosqueáveis fixados à madeira tratada com soluções preservativas preparadas com creosoto vegetal, em condições de campo. Obteve-se o creosoto vegetal bruto por meio da destilação à temperatura de 110 - 255ºC do alcatrão vegetal. Uma fração dos destilados foi lavada com solução a 9% de bicarbonato de sódio, obtendo-se o creosoto vegetal purificado. Ambas as frações foram enriquecidas com 3% de naftenato de cobre; 3% de naftenato de zinco; 3% naftenato de cobalto; 2% de TBTO; 2% de tribromofenato de tubutil-estanho; 2% de pentaclorofenol; ou 0,4% de trióxido de arsênico. Foram preparadas 16 soluções, sendo 14 enriquecidas, além do creosoto vegetal bruto e do creosoto vegetal purificado. Estacas confeccionadas com madeira de alburno de Eucalyptus grandis foram tratadas pelo processo de célula- cheia (processo Bethell. Após o tratamento, parafusos auto-rosquéaveis de ferro zincado foram fixados às estacas. O ensaio foi instalado em três localidades da Zona da Mata de Minas Gerais (Viçosa, Ponte Nova e Leopoldina. A corrosividade das soluções de creosoto vegetal foi comparada à causada pelo creosoto mineral. As soluções preparadas com creosoto vegetal purificado foram menos corrosivas que suas similares preparadas com creosoto vegetal bruto, assemelhando-se ao creosoto mineral.The objective of this research was to evaluate the corrosion of screws fixed into wood treated with preservative solutions of wood tar creosote.

    Full Text Available O uso de produtos fitossanitários aplicados via sementes é uma prática rotineira para a cultura do milho. No entanto, a crescente preocupação com o meio ambiente e com a segurança humana torna necessário o desenvolvimento de tecnologias que venham reduzir os riscos com a manipulação destes fitoprotetores, sendo este um dos principais objetivos do uso de polímeros. Assim, com este trabalho, objetivou-se avaliar a qualidade fisiológica e sanitária de sementes de milho submetidas a tratamentos fitossanitários em associação com diferentes polímeros, durante o armazenamento. Para tanto, as sementes de milho dos híbridos AG9010 e AG122 foram tratadas ou não com inseticida carbofuran (nome comercial: Furazin na dosagem de 1,5 L/100 kg de sementes e em mistura com o fungicida fludioxonil (nome comercial: Maxin na dosagem de 100 mL/100 kg de sementes. Durante o tratamento das sementes foram utilizados ou não os polímeros 1519 na dosagem de 50 mL/100 kg de sementes e 1080 na dosagem de 100 mL/100 kg de sementes. As sementes foram acondicionadas em embalagens de papel multifoliado e armazenadas durante seis meses sob condições ambientais. A qualidade das sementes foi avaliada antes e após o armazenamento, por meio das seguintes determinações: teste de germinação, teste de frio, teste de emergência em bandeja, determinação de sementes infestadas, índice de velocidade de emergência e teste de sanidade. Conclui-se que a peliculização não afeta a qualidade fisiológica das sementes de milho e a aplicação de Furazin e/ou Maxin, sobre as sementes de milho, é tecnicamente viável. Sementes de milho de alta qualidade inicial podem ser tratadas e armazenadas por seis meses, sem que haja comprometimento de sua qualidade fisiológica.The use of phytosanitary chemicals applied via seeds is a routine practice for corn crop, nevertheless, the growing concern about environment and human security make it necessary to develop new

    Full Text Available O revestimento com polímeros, associado ao tratamento químico de sementes, vem sendo utilizado em culturas com o propósito de fixar produtos químicos. O objetivo do trabalho foi avaliar o efeito do armazenamento na qualidade de sementes de feijão (Phaseolus vulgaris L. revestidas com polímeros e tratadas com diferentes fungicidas. As sementes foram inoculadas por imersão a vácuo, em suspensão de inóculo de Colletotrichum lindemuthianum (5x10(5 conídios/mL, fungo-teste utilizado. Os fungicidas benomyl, carbendazin e captan, nas formulações pó molhável, suspensão concentrada e pó seco, respectivamente, foram aplicados prévia ou concomitantemente à aplicação de uma mistura de dois polímeros à base de tintas de polímeros vinílicos fosca e brilhante. Apesar de a velocidade de germinação das sementes de feijão revestidas e tratadas ter sido reduzida, a porcentagem de germinação não foi afetada negativamente pelo revestimento com os polímeros testados. O revestimento com polímeros não prejudicou a eficiência dos fungicidas testados no controle de fungos em geral, sob nenhuma das duas formas de aplicação, ao longo dos quatro meses de armazenamento. O revestimento com estes polímeros pode afetar a eficiência de controle de patógenos nestas sementes, positiva ou negativamente, dependendo do fungicida utilizado e de sua forma de aplicação e dependendo do patógeno presente nas sementes.Coating seeds with polymers associated with chemicals is used to promote a better fixation of seed treatment products, and therefore minimizing toxic hazards. The objective of this work was to verify the effect of four-month storage on quality of dry bean (Phaseolus vulgaris L. seed coated with polymers, and treated with fungicides. Bean seeds were inoculated by immersion in a suspension of Colletotrichum lindemuthianum (5x10(5 conidia/mL, applied under vacuum. After the inoculation, seeds were treated with different types of

    Full Text Available Anterior approach ultrasound guided arthrogram injections are a quick reliable way of injecting contrast prior to MRI scan. We did a retrospective study on patients, previously injected and scanned at our clinic, to compare the more manifested posterior approach with the anterior approach. The success rate for successful intra-articular injections for the anterior approach far outweighs the posterior approach. Also the anterior approach is more tolerable for patients as the injections are much quicker and seemingly less painful. In our knowledge it is thus far better to perform anterior approach shoulder arthrogram injections than posterior approach injections

    The drainage of the superficial middle cerebral vein (SMCV) is classified into four subtypes. The sphenobasal vein (SBV) drains from the SMCV to the pterygoid venous plexus at the temporal skull base. Epidural procedures in the standard anterior transpetrosal approach (ATPA) may damage the route of the SBV. We report a case in which modified surgical procedures via the ATPA were used to preserve the SBV. A 45-year-old man complained of right facial pain. Magnetic resonance images revealed a right cerebellopontine tumor suggestive of an epidermoid cyst. Right carotid angiography revealed that the SMCV drained into the pterygoid venous plexus via the SBV. The convexity dura mater of the temporal lobe was cut and the anterior part of the temporal lobe was retracted subdurally. The SBV was visualized from the subdural side. The basal dura mater of the temporal lobe posterior to the SBV was cut and the posterior part of the temporal lobe was retracted epidurally. After dissecting the dura mater medial to the greater petrosal nerve and to the edge of the petrous apex, the petrous apex was exposed and drilled out without injuring the SBV. The superior petrous sinus and the tentorium were cut. The tumor compressed the root exit zone of the trigeminal nerve. The tumor was grossly totally removed. The modified ATPA (epidural anterior petrosectomy with subdural visualization of the SBV) is effective in preserving the SBV.

    Full Text Available Objetivou-se avaliar o efeito do tratamento da cana-de-açúcar com óxido de cálcio (CaO sobre o comportamento ingestivo em caprinos. Foram utilizados oito caprinos da raça Saanen, machos castrados, com peso corporal médio de 22,6 kg e 4 meses de idade, distribuídos em dois quadrados latinos 4 × 4, com quatro períodos experimentais de 14 dias. Os animais foram mantidos em baias individuais de 1,2 m², com piso ripado de madeira, providas de comedouros e bebedouros individuais. As dietas foram formuladas para ser isoproteicas e conter 14% de proteína bruta (PB e apresentaram 70% de cana-de-açúcar tratada com 0; 0,75; 1,5 ou 2,25% de óxido de cálcio (com base na matéria natural corrigida com 1% de ureia e 30% de concentrado fornecidas a vontade. A cana-de-açúcar com a adição das doses de óxido de cálcio, foi triturada em desintegradora estacionária, pesada e acondicionada em baldes plásticos de 50 L, tratada com o óxido de cálcio e fornecida aos animais após 24 horas de armazenamento. Os tempos despendidos em alimentação, ruminação (min/dia, min/kg MS e min/kg FDN e ócio (min/dia não foram afetados pela adição de óxido de cálcio à cana-de-açúcar. A adição de óxido de cálcio à cana-de-açúcar não influenciou a eficiência em alimentação e ruminação, mas provocou redução do tempo médio despendido por período de alimentação. O comportamento ingestivo de caprinos em crescimento não é afetado pela utilização de dietas contendo cana-de-açúcar tratada com até 2,25% de óxido de cálcio.The objective of this work was to evaluate the effect of sugar cane treated with calcium oxide (CaO on ingestive behavior in goats.

    Diana Catalina Gutiérrez

    2008-10-01

    Full Text Available Mediante un modelo de equilibrio general computable, en el que se discrimina un sector informal en la economía, se modela el sector formal como un mercado de competencia monopolística. Además de incluir mercados de trabajo discriminados, este modelo también evalúa el impacto del creciente flujo de inversión extranjera, del aumento de precio de los bienes básicos, y del aumento del volumen de las exportaciones sobre la economía colombiana. Se concluye que algo más de la mitad del crecimiento observado puede explicarse por el efecto de los factores mencionados. No obstante, se señala la importancia de las políticas internas para aprovechar las coyunturas favorables, y para minimizar el efecto de circunstancias negativas sobre el desempeño económico.
