    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.

    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.

    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.

    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.

    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.

    2014-09-01

    Congenital anterior urethral diverticulum (CAUD) may be found all along the anterior urethra and may present itself at any age, from infant to adult. Most children with this condition present with difficulty in initiating micturition, dribbling of urine, poor urinary stream, or urinary tract infection. A careful history will reveal that these children never had a good urinary stream since birth, and the telltale sign is a cystic swelling of the penile urethra. In this paper, we present two cases of CAUD that were managed by excision of the diverticulum with primary repair. PMID:26328174

    2011-01-01

    Toxic anterior segment syndrome (TASS) is a general term used to describe acute, sterile postoperative inflammation due to a non-infectious substance that accidentally enters the anterior segment at the time of surgery and mimics infectious endophthalmitis. TASS most commonly occurs acutely following anterior segment surgery, typically 12-72h after cataract extraction. Anterior segment inflammation is usually quite severe with hypopyon. Endothelial cell damage is common, resulting in diffuse corneal edema. No bacterium is isolated from ocular samples. The causes of TASS are numerous and difficult to isolate. Any device or substance used during the surgery or in the immediate postoperative period may be implicated. The major known causes include: preservatives in ophthalmic solutions, denatured ophthalmic viscosurgical devices, bacterial endotoxin, and intraocular lens-induced inflammation. Clinical features of infectious and non-infectious inflammation are initially indistinguishable and TASS is usually diagnosed and treated as acute endophthalmitis. It usually improves with local steroid treatment but may result in chronic elevation of intraocular pressure or irreversible corneal edema due to permanent damage of trabecular meshwork or endothelial cells.

    Full Text Available O carcinoma epidermóide da laringe é a sexta neoplasia mais comum, sendo uma das neoplasias malignas mais freqüentes na cabeça e pescoço, ocupando o segundo lugar imediatamente após o câncer da cavidade oral. FORMA DE ESTUDO: Estudo clínico retrospectivo. MATERIAL E MÉTODO: Entre os anos de 1991 e 2003, 24 pacientes portadores de lesões glóticas envolvendo a comissura anterior foram submetidos a laringectomia frontal anterior com epiglotoplastia descrita por Tucker e colaboradores no ano de 1979. RESULTADO: Nossos resultados confirmam aqueles encontrados em outras publicações. Não ocorreram mortes no pós-operatório e o seguimento foi relativamente simples. Todos os pacientes foram decanulizados e recuperaram um efetivo trato digestivo e aéreo. CONCLUSÃO: Nossos achados mostram que a laringectomia pela técnica de Tucker é uma cirurgia efetiva para o tratamento dos carcinomas glóticos que acometem a comissura anterior e a porção membranosa das cordas vocais com a motilidade preservada, pois tais lesões não devem ser tratadas pela ressecção endoscópica trans-oral ou por uma laringectomia fronto lateral.Squamous cell carcinoma of the larynx is the sixth most common neoplasia, being the second neoplasia of the head and neck, after oral cancer. STUDY DESIGN: Retrospective clinical study chart review. MATERIAL AND METHOD: From 1991 to 2003, 24 patients whose glottic lesions involving anterior comissure were operated with a reconstructive anterior frontal laryngectomy with epiglotoplasty, such as described by Tucker et al in 1979. RESULTS: Our functional results confirm those reported in the previous publications. There were no post-operative mortalities and follow-up was usually uncomplicated. All patients underwent decanulation and were able to eat by tract normal. CONCLUSION: Our findings show that partial laryngectomy by Tucker's technique is an effective surgical approach for glottic carcinoma at the anterior comissure

  12. Anterior knee pain

    International Nuclear Information System (INIS)

    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

  19. Anterior cruciate ligament reconstruction

    International Nuclear Information System (INIS)

    This paper determines the efficacy of MR imaging in evaluation of the anterior cruciate ligament (ACL) following reconstructive surgery. Forty-three MR examinations were performed in 33 patients who had undergone previous arthroscopic ACL reconstruction with patellar bone-tendon- bone autografts (postoperative period, 1-24 months; mean, 5.2 months). Of the 40 studies performed in clinically stable knees (30 patients), MR demonstrated a well-defined, signal void ACL graft in 36. Of the three studies performed in three patients with clinical ACL laxity or suspected tear, the neoligament was of intermediate definition in one and nondiscernible in the other two. As in the native knee, buckling of the PCL was suggestive of ACL insufficiency. Bone tunnel placement, patellar tendon changes, and joint effusions were also evaluated

    1999-10-15

    Anterior hip pain is a common complaint with many possible causes. Apophyseal avulsion and slipped capital femoral epiphysis should not be overlooked in adolescents. Muscle and tendon strains are common in adults. Subsequent to accurate diagnosis, strains should improve with rest and directed conservative treatment. Osteoarthritis, which is diagnosed radiographically, generally occurs in middle-aged and older adults. Arthritis in younger adults should prompt consideration of an inflammatory cause. A possible femoral neck stress fracture should be evaluated urgently to prevent the potentially significant complications associated with displacement. Patients with osteitis pubis should be educated about the natural history of the condition and should undergo physical therapy to correct abnormal pelvic mechanics. "Sports hernias," nerve entrapments and labral pathologic conditions should be considered in athletic adults with characteristic presentations and chronic symptoms. Surgical intervention may allow resumption of pain-free athletic activity. PMID:10537384

Flea infestation is associated with poverty and occurs in resource-poor communities in South and Central America, the Caribbean and Sub-Saharan Africa. In Brazil, it is widespread in urban squatter settlements, villages in the rural hinterland and in traditional fishing communities along the coast. Standard therapy for tungiasis consists of removing the embedded flea with a sterile needle, and using an antibiotic agent in case of secondary infection. At present, there is no drug in the market with satisfactory clinical efficacy. We describe a case of generalized Tunga penetrans infestation that was treated with oral ivermectin.

  8. Anterior approach for knee arthrography

    International Nuclear Information System (INIS)

    Objective. To develop a new method of magnetic resonance arthrography (MRA) of the knee using an anterior approach analogous to the portals used for knee arthroscopy.Design. An anterior approach to the knee joint was devised mimicking anterior portals used for knee arthroscopy. Seven patients scheduled for routine knee MRA were placed in a decubitus position and under fluoroscopic guidance a needle was advanced from a position adjacent to the patellar tendon into the knee joint. After confirmation of the needle tip location, a dilute gadolinium solution was injected.Results and conclusion. All the arthrograms were technically successful. The anterior approach to knee MRA has greater technical ease than the traditional approach with little patient discomfort. (orig.)

    Anterior ankle impingement results from an impingement of the ankle joint by a soft tissue or osteophyte formation at the anterior aspect of the distal tibia and talar neck. It often occurs secondary to direct trauma (impaction force) or repetitive ankle dorsiflexion (repetitive impaction and traction force). Chronic ankle pain, swelling, and limitation of ankle dorsiflexion are common complaints. Imaging is valuable for diagnosis of the bony impingement but not for the soft tissue impingemen...

Purpose: To evaluate anterior chamber depth and axial length in patients during HD sessions. Methods: A total of 67 eyes of 35 patients were prospectively enrolled. Axial length and anterior chamber depth were measured using ultrasonic biometry, and these measures were evaluated at three different times during HD sessions. Body weight and blood pressure pre- and post-HD were also measured. Results: There was no difference in the axial length between the three measurements (P = 0.241. We observed a significantly decreased anterior chamber depth (P = 0.002 during HD sessions. Conclusion: Our results support the idea that there is a change in anterior chamber depth in HD sessions.

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.

    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.

Assim, o presente trabalho tem por objetivo avaliar o potencial germinativo e a sanidade de sementes de cupuaçu tratadas com diferentes fungicidas por um período de seis meses. As sementes avaliadas foram da variedade redondo, estas foram submetidas a seis diferentes tratamentos com fungicidas e armazenadas a temperatura de 5°C por seis meses. A cada dois meses avaliaram-se a porcentagem de germinação, IVE, teste de frio, envelhecimento acelerado, teor de água, condutividade elétrica e sanidade das sementes. Dentre as características avaliadas não houve interação somente para teor de água e condutividade elétrica. Observou-se efeito positivo dos tratamentos com fungicidas no controle dos fungos sem comprometer a germinação quando comparados a testemunha. O fungicida Captan apresentou os melhores resultados para todas as características avaliadas. Verificou-se ainda que o potencial germinativo é comprometido após dois meses de armazenamento independente do tratamento utilizado.

    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 Herniation of the anterior lens capsule is a rare abnormality in which the capsule bulges forward in the pupillary area. This herniation can be mistaken for an anterior lenticonus where both the capsule and the cortex bulge forward. The exact pathology behind this finding is still unclear. We report the clinical, ultrasound biomicroscopy (UBM and histopathological findings of a case of herniation of the anterior lens capsule. UBM helped to differentiate this entity from anterior lenticonus.

    2003-06-01

    Full Text Available A rare anomaly of the scalenus muscles is described. In this case, the right scalenus anterior muscle was absent. As a substitute for this muscle, some aberrant muscle slips arose from the lower vertebrae and descended in front of the ventral rami of the lower cervical nerves. These aberrant slips then ran between the ventral rami of the the eighth cervical and first thoracic nerves, and were fused with the right scalenus medius muscle. Thus, the subclavian artery and vein ran in front of the aberrant slips, together with the ventral ramus of the first thoracic nerve. The aberrant muscle slips issued 2 accessory bundles. One bundle ran between the ventral rami of the fourth and fifth cervical nerves and was fused with the scalenus medius muscle; the other bundle ran between the ventral rami of the fifth and sixth cervical nerves and was fused with the scalenus medius muscle.

    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. PMID:27103865

    2016-01-01

    Background The aims of this study were to investigate the clinical characteristics of patients with combined anterior instability and superior labrum from anterior to posterior (SLAP) lesions, and to analyze the effect of concomitant SLAP repair on surgical outcomes. Methods We retrospectively reviewed patients who underwent arthroscopic stabilization for anterior shoulder instability between January 2004 and March 2013. A total of 120 patients were available for at least 1-year follow-up. Forty-four patients with reparable concomitant detached SLAP lesions (group I) underwent combined SLAP and anterior stabilization, and 76 patients without SLAP lesions (group II) underwent anterior stabilization alone. Patient characteristics, preoperative and postoperative pain scores, Rowe scores, and shoulder ranges of motion were compared between the 2 groups. Results Patients in group I had higher incidences of high-energy trauma (p = 0.03), worse preoperative pain visual analogue scale (VAS) (p = 0.02), and Rowe scores (p = 0.04). The postoperative pain VAS and Rowe scores improved equally in both groups without significant differences. Limitation in postoperative range of motion was similar between the groups (all p-value > 0.05). Conclusions Anterior instability with SLAP lesion may not be related to frequent episodes of dislocation but rather to a high-energy trauma. SLAP fixation with anterior stabilization procedures did not lead to poor functional outcomes if appropriate surgical techniques were followed. PMID:27247742

    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.

    Tripathi, R C; Bron, A J

    1975-01-01

    The clincopathological features and pathogenesis of secondary mosaic degeneration of the cornea (anterior crocodile shagreen of Vogt) are described. The structural basis for the normal anterior corneal mosaic pattern seems to lie in the particular arrangement of many prominent collagen lamellae of the anterior stroma that thake an oblique course to gain insertion into Bowman's layer. Since, at normal intraocular pressure, Bowman's layer is under tension, when viewed from the anterior surface the cornea appears smooth. By releasing the tension, however, a reproducible polygonal ridge pattern becomes manifest. It is suggested that a prolonged phthisical state of the eye is one condition wherein the mosaic pattern may become permanent and that, as a secondary event, this is followed by irregular calcification of Bowman's layer which particularly involves the ridges projecting into the epithelium. Biomicroscopically these ridges corresponded to the branching reticular arrangement of the mosaic opacities. Images PMID:1079137

    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.

    Full Text Available A superfície de uma borracha de etileno-propileno-dieno (EPDM vulcanizada foi modificada via plasma por microondas, com gases Ar, Ar/O2, N2/O2 e N2/H2, tendo como objetivo melhorar as propriedades adesivas da superfície. A técnica FT-IR/UATR foi escolhida para caracterizar as superfícies após tratamento, pois apresentou menor interferência dos ingredientes da formulação da EPDM, dentre as técnicas analisadas (ATR/KRS-5 e Ge. Grupos oxigenados foram inseridos na superfície da amostra tratada, mesmo quando não foi utilizado o oxigênio, pois estes grupos foram formados quando a superfície ativada foi exposta à atmosfera. Já em tratamentos contendo N2, grupos oxigenados e possíveis grupos nitrogenados foram identificados por FT-IR. Redução nos valores do ângulo de contato, aumento no trabalho de adesão e aumento no ensaio de resistência ao descascamento (EPDM × Poliuretano foram observados após tratamento com Ar e N2/H2, resultando em melhora nas propriedades adesivas da superfície tratada.

  16. Aphasia following anterior cerebral artery occlusion

    International Nuclear Information System (INIS)

    We have report two cases of aphasia that had infarcts in the distribution of the left or right anterior cerebral artery, as confirmed by computed tomography. Case 1 is a right-handed, 65-year-old man in whom computerized tomographic scanning revealed an infarction of the territory of the left anterior cerebral artery after the clipping of the anterior communicating artery aneurysm. The standard language test of aphasia (SLTA) revealed non-fluent aphasia with dysarthria, good comprehension, almost normal repetition with good articulation, and a defectiveness in writing. This syndrome was considered an instance of transcortical motor aphasia. Although three years had passed from the onset, his aphasia did not show any improvement. Case 2 is a 37-year-old man who is right-handed but who can use his left hand as well. He was admitted because of subarachnoid hemorrhage from an anterior communicating aneurysm. Because of postoperative spasm, an infarction in the distribution of the right anterior cerebral artery developed. He was totally unable to express himself vocally, but he could use written language quite well to express his ideas and had a good comprehension of spoken language. This clinical picture was considered that of an aphemia. After several weeks, his vocalization returned, but the initial output was still hypophonic. (J.P.N.)

    Full Text Available Fibra de Retamo Liso (telinemonspessulana fue mezclada en una matriz polimérica formada por: polietileno de baja densidad (LDPE y poliestireno de alto impacto (HIPS en relación 70:30 respectivamente. La fibra natural fue sometida a reducción de tamaño entre 1700 y 850 µm; se le realizó tratamiento superficial de mercerización; el contenido de humedad fue 0,17%. El análisis termo gravimétrico (TGA muestra que la fibra tratada tiene estabilidad de 200,53 °C. La elaboración del compuesto se realizó en mezclador interno y la técnica de obtención de las probetas fue mediante moldeo por compresión. Se evaluó el efecto del agente entrecruzante peróxido de dicumilo (DCP en compuestos con varios porcentajes de fibra: 0; 10; 25; 50 phr. La adición de DCP (1 phr en los compuestos, mejora significativamente las propiedades de tensión con respecto a similares concentraciones de fibra; sin embargo, esta diferencia en los valores de las propiedades disminuye progresivamente cuando la cantidad de fibra se aproxima a 50 phr. El aumento en la concentración de fibra afecta negativamente las propiedades de tensión, con excepción del Módulo de Elasticidad y la Resistencia a la Fluencia. La causa principal es originada por la baja adhesión interfacial fibra natural-matriz polimérica, claramente evidenciada en las imágenes SEM.

    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.

    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.

    1993-04-01

    Dental plaster casts of 235 Maasai, 116 Kikuyu and 61 Kalenjin children aged 3-16 yr were studied to determine the incidence and magnitude of diastemas, overbite, overjet and anterior open bite. The highest prevalence of diastema was amongst the Maasai (61.3%), of overbite (84%) and overjet (99%) amongst the Kikuyu, and of anterior open bite amongst Kalenjin (24%), with values greater than 0.4 mm up to 11.5 mm. Comparison of the mean values showed that diastema (1.77 mm) and overjet (4.4 mm) were greatest in Maasai, overbite (3.53 mm) in Kalenjin, and anterior open bite (3.50 mm) in Kikuyu. In the total sample, the prevalence and mean of diastema were 49%, 1.68 mm; of overbite 77.4%, 2.96 mm; of overjet 88.6%, 3.83 mm; and of anterior open bite 16.5%, 2.69 mm (with values between 0.4-11.5 mm), while 5.5% had an edge-to-edge bite (-0.5-0.5 mm). The prevalence of diastema decreased whilst its magnitude increased with age. The mean values of overbite and overjet increased, while those for anterior open bite decreased with age. The mean values of diastema, overbite and overjet were greater amongst the females, but the difference was significant only for overjet. The high prevalence and greater values of measurements of anterior tooth relations may be related to variable growth of the bimaxillary dentoalveolar complex and soft tissue influences. This may be important in orthodontic treatment planning, dental prostheses and other clinical dental treatments in Kenyan populations. PMID:8517805

    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.

  4. Roentgenographic findings following anterior cervical fusion

    International Nuclear Information System (INIS)

    We reviewed the pre- and postoperative lateral cervical roentgenograms in 90 patients who had anterior fusions and compared their findings with age and sex-matched people without neck problems. The average interval from surgery to review was 5 years. Preoperatively, all patients had a higher incidence of degenerative spondylosis at the levels to be fused than their asymptomatic counterparts. Postoperatively, there was no difference in the incidence of degenerative change between the operated and the control group at the levels above and below the fusion with the exception of anterior osteophyte formation which was more frequent in those with fusions.

    Full Text Available En la zona de Poasito de Alajuela, se evaluó la acción del antagonista Gliocladium roseum, en forma individual y en conjunto con los fungicidas empleados en la finca, para el combate de Botrytis cinerea en fresa; comparándose los resultados contra los obtenidos con el manejo comercial. Se empleó un diseño de bloques completos al azar con 4 repeticiones y se hicieron aplicaciones semanales del antagonista (a una concentración ³ 107 conidios ml-1 durante un período aproximado de 4 meses (julio-octubre del 2000. Se evaluó la incidencia de moho gris en condiciones de campo y poscosecha, así como el efecto de los fungicidas aplicados sobre la germinación de los conidios del antagonista, mediante una prueba in vitro. Se obtuvo un combate más efectivo de la enfermedad en condiciones de campo al emplear el biocontrolador sólo o en conjunto con los fungicidas, con respecto al manejo comercial que se hace de la misma. En poscosecha, el desempeño del antagonista fue estadísticamente igual al del combate químico. Estos resultados muestran que los fungicidas aplicados no afectan considerablemente al antagonista, lo que se corroboró con la prueba in vitro. Al emplear G. roseum para el combate de B. cinerea no sólo se logra combatir efectivamente a este, sino también el resto de los patógenos (Colletotrichum, Phytophthora, Rhizoctonia, Rhizopus,Alternaria, Fusarium, Verticillium y Penicillium, ya que el porcentaje de frutas sanas es mayor al integrar la acción del antagonista al manejo de enfermedades de la finca. Sin embargo, estas diferencias no son estadísticamente significativas. Por lo anterior se concluye que G. roseum constituye una posible alternativa de manejo integrado del moho gris en fresa.

    2015-09-01

    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 The anterior retropharyngeal approach (ARPA accesses anteriorly situated lesions from the clivus to C3, in patients with a short neck, Klippel Feil anomaly or those in whom the C2-3 and C3-4 disc spaces are situated higher in relation to the hyoid bone and the angle of mandible where it is difficult to approach this region using the conventional anterior approach, due to the superomedial obliquity of the trajectory. The ARPA avoids the potentially contaminated oropharyngeal cavity providing for a simultaneous arthrodesis and instrumentation during the primary surgical procedure. Experience of five patients with high cervical extradural compression, who underwent surgery using this approach between 1994 and 1999, is presented. The surgical procedures included excision of ossified posterior longitudinal ligament (n=2; excision of prolapsed disc and osteophytes (n=2; and excision of a vertebral body neoplasm (n=1. Following the procedure, vertebral arthrodesis was achieved using an iliac graft in all the patients. Only one patient with vertebral body neoplasm required an additional anterior cervical plating procedure for stabilisation the construct. The complications included transient respiratory insufficiency and neurological deterioration in two patients; and, pharyngeal fistula and donor site infection in one patient.

    Three male and two female patients with anorgasmia and dissociated sensory loss due to an anterior spinal cord syndrome are described. Clinical, neurophysiological and quantitative sensory evaluation revealed preservation of the large fibre dorsal column functions from the lumbosacral segments with concomitant severe dysfunction or absence of the small fibre neospinothalamic mediated functions. These findings indicate a role for the spinothalamic system in orgasm.

    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 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.

    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.

  10. Anterior approaches to the upper thoracic spine

    International Nuclear Information System (INIS)

    The upper thoracic spine region is difficult to access from an anterior approach because of the surrounding bones (ribs, sternum and scapulae) and organs (heart, lung and great vessels). The outcomes of 37 consecutive cases with lesions in the upper thoracic spine region (T1-4) were reviewed to study surgical approaches to the upper thoracic spine. We used anterior approaches in 13 cases. A full sternotomy was performed in 6 cases (5 cases ossification of posterior longitudinal ligament (OPLL), 1 case herniated disc), a high thoracotomy was performed in 6 cases (3 cases herniated disc, 2 cases spinal cord tumor, 1 case TB spine), and a partial resection of a unilateral sternoclavicular joint was performed in 1 case. A sternotomy is thought to be useful for OPLL in the T1-3 region, whereas a high thoracotomy is recommended for unilateral anterior lesions and lesions extending below the T3/4 level. Reconstructive CT sagittal images can supply useful anatomical informations for selecting a surgical approach. (author)

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.

La sección Fumigati incluye unas pocas especies anamorfas del género Aspergillus. Las especies que son teleomorfas se encuentran dentro del género Neosartorya. Este es un moho resistente al calor que causan problemas en las industrias alimentarias o enfermedades en los seres humanos. Sus ascosporas han sido aisladas a partir de frutas, pulpas y jugos, ya que pueden sobrevivir a los tratamientos de térmicos industriales pudiendo aparecer la contaminación post-pasteurización. El objetivo fue caracterizar aislados de Neosartorya de frutillas frescas recién cosechadas y tratadas térmicamente, analizando la ornamentación de las ascosporas, toxicidad y resistencia térmica. Se aislaron las colonias, y se identificaron macro y microscópicamente siguiendo la metodología de Pitt y Hocking (2009, de 60 muestras. Se caracterizaron las ascosporas por microscopía electrónica de barrido. Se determinó la capacidad toxicogénica de los extractos por cromatografía líquida de alta eficiencia. Se evaluó la resistencia térmica a diferentes temperaturas. Se aislaron 18 cepas de Neosartorya de frutillas recién cosechadas, y otros mohos termorresistentes como Arthrinium phaeospermum, Byssochlamys nivea y Talaromyces macrosporus.

    Full Text Available El género Aspergillus es uno de los géneros fúngicos más estudiados y de gran impacto a nivel industrial. La sección Fumigati incluye unas pocas especies anamorfas del género Aspergillus. Las especies que son teleomorfas se encuentran dentro del género Neosartorya. Este es un moho resistente al calor que causan problemas en las industrias alimentarias o enfermedades en los seres humanos. Sus ascosporas han sido aisladas a partir de frutas, pulpas y jugos, ya que pueden sobrevivir a los tratamientos de térmicos industriales pudiendo aparecer la contaminación post-pasteurización. El objetivo fue caracterizar aislados de Neosartorya de frutillas frescas recién cosechadas y tratadas térmicamente, analizando la ornamentación de las ascosporas, toxicidad y resistencia térmica. Se aislaron las colonias, y se identificaron macro y microscópicamente siguiendo la metodología de Pitt y Hocking (2009, de 60 muestras. Se caracterizaron las ascosporas por microscopía electrónica de barrido. Se determinó la capacidad toxicogénica de los extractos por cromatografía líquida de alta eficiencia. Se evaluó la resistencia térmica a diferentes temperaturas. Se aislaron 18 cepas de Neosartorya de frutillas recién cosechadas, y otros mohos termorresistentes como Arthrinium phaeospermum, Byssochlamys nivea y Talaromyces macrosporus.

    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.)

    Full Text Available Background: Evaluation of result of anterior cervical approach with manubriotomy and anterior instrumentation in tuberculosis of cervicothoracic spine in terms of the neurological recovery, reconstruction of spine and prevention of deformity along with relief of pain. Materials and Methods: All five patients with cervicothoracic caries spine had surgery through anterior cervical approach with manubriotomy in our hospital and underwent excision of the involved vertebrae and intervertebral discs followed by anterior spinal reconstruction with titanium spacer cage filled with cancellous iliac crest bone graft and Orion plate with locking screw. Antitubercular drugs were administered for 12 months. The follow-up period ranged from 12 to 36 months. Results: Analysis of result was done on the basis of clinical and radiological criteria. Clinical assessment based on Frankel grade and modified JOA score showed significant improvement from preoperative findings. Radiological assessment showed osteointegration, no spinal instability and no progression of the deformity. The pain control, based on visual analog scale changed from a pre-operative average of 7.5 to 2 at the last follow-up thereby indicating significant improvement and all patients returned to preoperative functional status. One patient had transient hoarseness of voice. No other complication had been encountered in the immediate post operative and during the follow-up period. Conclusions: Our study showed that anterior cervical approach with manubriotomy and anterior insertion of titanium cage, filled with autogenous bone graft, secured with locking plate instrumentation has a successful role in the eradication of infection, neurological recovery, segmental spinal reconstruction and it also reduces surgical time, blood loss, and surgical complications and approach related comorbidity in follow up period.

    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

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.

  5. Selection of operative procedures for anterior plagiocephaly

    International Nuclear Information System (INIS)

    The purposes of this study were to evaluate long-term results after surgical treatment for anterior plagiocephaly and to identify factors that might influence these results. And according to these results selection of operative procedures for plagiocephaly was discussed. From April 1, 1985 to December 31, 2002, 12 children with anterior plagiocephaly were treated by craniofacial surgery (frontoorbital advancement) or distraction osteogenesis in Saitama Children's Medical Center. Distraction osteogenesis was applied in 3 patients with mild deformities. Preoperative severity of the craniofacial deformities, the time of operations, operative methods and long-term results were analyzed in these cases. Preoperative deformities were classified by the classification system developed by Di Rocco C et al (1988) and surgical results were graded according to the grading system reported by Wagner JD et al (1995) at the end of follow-up period. Follow-up ranged from 1 to 12 years (mean 6.2±4.9). Morphological long-term surgical results in 12 cases with plagiocephaly as follows; excellent in 8 cases, good in 3 cases and poor in 1 case. At the end of follow-up, excellent craniofacial configurations were obtained in 8 cases operated on in less than 1 year after birth or with mild craniofacial deformities (grade II) preoperatively. And also complete normalization of endocranial base asymmetries on 3D-CTs were recognized in cases operated on in less than 1 year after birth regardless of surgical procedures. These results suggest that early craniofacial surgery is necessary for an infant to attain complete normalization of the craniofacial dysmorphology of anterior plagiocephaly in spite of operative methods.

    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 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)

  12. Approach-avoidance activation without anterior asymmetry

    2014-03-01

    Full Text Available Occasionally, the expected effects of approach-avoidance motivation on anterior EEG alpha asymmetry fail to emerge, particularly in studies using affective picture stimuli. These null findings have been explained by insufficient motivational intensity of, and/or overshadowing interindividual variability within the responses to emotional pictures. These explanations were systematically tested using data from 70 students watching 5 types of affective pictures ranging from very pleasant to unpleasant. The stimulus categories reliably modulated self-reports as well as the amplitude of late positive potential, an ERP component reflecting orienting towards motivationally significant stimuli. The stimuli did not, however, induce expected asymmetry effects either for the sample or individual participants. Even while systematic stimulus-dependent individual differences emerged in self-reports as well as LPP amplitudes, the asymmetry variability was dominated by stimulus-independent interindividual variability. Taken together with previous findings, these results suggest that under some circumstances anterior asymmetry may not be an inevitable consequence of core affect. Instead, state asymmetry shifts may be overpowered by stable trait asymmetry differences and/or stimulus-independent yet situation-dependent interindividual variability, possibly caused by processes such as emotion regulation or anxious apprehension.

    We describe the microanatomy of the perforating arteries arising from the anterior communicating artery complex (5 mm distal of the anterior cerebral artery, the anterior communicating artery, and 5 mm proximal of the distal anterior cerebral artery). Thirteen unfixed human brains were used in this study. The origin and number of perforators are described, as is the site of brain penetration, and results are correlated with previous studies. The hemodynamics of blood flow in relation to the formation of an anterior communicating artery aneurysm and different surgical approaches are mentioned. The neuropsychological outcome after aneurysm clipping with regards to the pattern of blood supply from the anterior cerebral artery complex is also discussed. PMID:9427956

El artículo propone transformar el concepto de "sitio centinela" incorporandole el requisito de la "representatividad cualitativa" mediante muestreos finalísticos sustentados en tipologías previas de las unidades espacio-poblacionales.

    Anterior fixation devices for the thoracolumbar spine have gained wide acceptance as viable alternatives to long-segment posterior fixation in cases of thoracolumbar spine trauma. This review was undertaken to evaluate the safety and efficacy of the Synthes anterior thoracolumbar locking plate (ATLP) system. Over a 3-year period, 31 patients with unstable traumatic fractures of the thoracolumbar spine underwent corpectomy, placement of a structural bone graft, and anterior fixation in which the Synthes ATLP system was used. Long-term follow-up data were obtained in 29 patients. Two patients were lost to follow up, one at 4 months and the other at 1 year. In the remaining patients, the average length of follow up was 20 months. In all patients radiographic evidence of solid bone fusion was demonstrated on follow-up plain x-ray films, and there were no signs or symptoms of pseudarthrosis. No patient suffered neurological deterioration as a result of surgery, and there was relatively little morbidity associated with this plating system. To date, none of the patients in this study has developed any delayed complications related to the fixation device. In one patient, who had sustained a severe flexion injury, loosening of the anterior fixation device occurred, and the patient developed progressive kyphosis, which required a posterior stabilization procedure. These results appear slightly better than those obtained in published studies in which other anterior plating systems were used, indicating that this system is safe and effective in the treatment of unstable fractures of the thoracolumbar spine.

  14. Mechanisms of anterior cruciate ligament injury

    International Nuclear Information System (INIS)

    The anterior cruciate ligament (ACL) may be injured by various mechanisms. Each mechanism is know to produce specific combinations of ligamentous and meniscal abnormalities. This paper reports that this project was undertaken to evaluate the ability of MR imaging to characterize fully these different patterns of ACL injury. Two hundred fifty knee MR examinations in patients with suspected ACL injury were reviewed retrospectively. The presence of ACL injury and associated ligamentous, capsular, meniscal, and bone marrow abnormalities were correlated with the clinical history and mechanism of injury. Surgical or arthroscopic follow-up was available in all patients. As expected, ACL injuries were found to have a broad spectrum of associated abnormalities identified by MR imaging. Several mechanism-specific patterns of ligamentous and meniscal injury were observed; however, patterns of bone marrow edema and injury proved to be the most useful in predicting the mechanism of injury

    Full Text Available Odontogenesis is a complex process wherein more than 200 genes are known to play a significant role in tooth development. An imbalance can lead to an abnormality in the number, size, shape or structure of the developing tooth/teeth. The presence of an extra dental lamina forms a supernumerary tooth. The supernumerary teeth are of two types: A rudimentary tooth where the supernumerary tooth does not resemble any tooth in the normal series or a supplemental tooth in which this anomalous tooth resembles one in the normal series. It is also very rare to encounter triple teeth in primary dentition. The union of these teeth may be through fusion, gemination, concrescence or a combination of fusion and gemination. Presented is a rare case of concrescence involving maxillary deciduous incisors and a supplemental tooth in a 7-year-old boy. The differential diagnosis, etiology, and complications of primary anterior triple teeth are discussed.

    To investigate magnetic resonance (MR) imaging of anterior cruciate ligament (ACL) tears, the authors retrospectively reviewed 39 MR imaging examinations in 39 patients. We classified the MR imaging patterns of the torn ACL into four types. Torn ACL appears as a homogeneous iso-intensity mass on Type I images; as a continuous thin and waving low-intensity band with or without high-signal-intensity spots on the Type II images; as a disrupted band with a high-signal-intensity area on Type III images and as an absence of the ACL on Type IV images. We also report secondary lesions on MR imaging findings associated with tears of the ACL, posterior cruciate ligament index and bone bruising, in our patients. (author).

    On 546 knees, the authors have obtained MR images (0.5 T or 1.5 T). The protocol included 5-mm-thick contiguous sagittal and oblique coronal images (in the plane of the anterior cruciate ligament [ACL]) and T1-, proton-density-, and T2-weighted sequences. In 174 patients, correlations with arthroscopic or surgical findings were available. In these cases, sagittal and oblique coronal images were retrospectively and separately read by two radiologists, who were blinded to other results. The mean accuracy of sagittal MR images alone was 88% for the depiction of partial and complete ACL tears, intraligamental bleeding, and scarring; the accuracy of oblique coronal images alone was 96%. Use of sagittal and oblique coronal images together achieved 98% accuracy

    Bone contusions are an important ancillary finding of many knee injuries. Not only are they a source of pain, they may suggest a mechanism of injury or a specific derangement of the knee joint. We have encountered a small number of patients being evaluated for anterior cruciate ligament (ACL) tears with unexplained patellar and tibial edema at magnetic resonance (MR) imaging. We present three individuals with contusions of the inferior patella with a corresponding contusion of the anteromedial tibial plateau. Internal derangements in these patients were similar to other individuals with acute ACL tears, however osseous contusions were more widespread. In conclusion, patellotibial contusions are rare and may indicate an injury with forces greater than usually encountered in most ACL tears. A careful search for uncommon associated injuries is prudent in these high-energy knee injuries. PMID:24037484

    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

    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.

    A 70-year-old man presented to accident and emergency with an isolated anteriorly dislocated shoulder, in the absence of a concomitant fracture. There was no neurovascular deficit at presentation, and the shoulder was reduced under sedation, using the Kocher's technique. Following this, the patient developed signs of hypovolaemic shock. Clinical examination revealed an expanding fullness in the deltopectoral area, with compromise of the limb neurovascular status. CT imaging confirmed an expanding haematoma from the axillary vessels, restricting left lung expansion. Once resuscitated, the patient was transferred to theatre for exploration of the bleeding vessels. Intraoperative findings included an avulsed anterior circumflex humeral artery that was subsequently ligated. Postoperatively, the patient developed axillary, radial, median and ulnar nerve neuropraxia, which improved clinically prior to discharge. The patient was ultimately discharged home after a lengthy inpatient stay. PMID:26969353

    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. genesis 54:3-18, 2016. © 2016 Wiley Periodicals, Inc. PMID:26528772

    A 51-year-old woman presented with a distal anterior cerebral artery aneurysm (DACAA) manifesting as severe headache and monoparesis of the left lower limb. Computed tomography revealed subarachnoid hemorrhage in the interhemispheric fissure, bilateral sylvian fissures, and basal cistern, and a hematoma in the supracallosal region. Angiography showed a large aneurysm (23 x 18 mm) located on the distal end of the azygos anterior cerebral artery (azygos ACA) at the supracallosal portion. T2-weighted magnetic resonance imaging demonstrated the hematoma as a mixed intensity mass, compressing the corpus callosum downward, and the aneurysm as a flow void anterior to the hematoma. Unilateral frontoparietal parasagittal craniotomy was performed with a horse-shoe shaped incision. The aneurysm was clipped via the interhemispheric approach, and the hematoma was aspirated. Postoperative angiography showed disappearance of the aneurysm and intact azygos ACA. The patient was discharged with mild monoparesis, paresthesia of the left lower limb and diagnostic dyspraxia. DACAA almost always arises at or near the genu of the corpus callosum and is often associated with vascular anomaly. In the literature, 22 of 26 cases of large and giant DACAA were located at or near the genu, but only 3 cases, including ours, in the supracallosal area. 11 cases were associated with azygos ACA. Therefore, hemodynamic stress caused by vascular anomaly may be involved in the formation of large or giant DACAA in contrast with cases of normal DACAA. PMID:9789300

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.

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

    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 70ml) 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 1ml. 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

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”.

    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.

    The purpose of this study was to evaluate using MRI the natural healing of the anterior cruciate ligament (ACL) when treated conservatively by early protective motion. Consecutive acute complete intraligamentous ruptures of the ACL in 50 cases that were allowed to heal without surgery were evaluated before and after 3 month treatment by MRI, arthroscopy, and stress radiographs. Twenty-nine of the 50 patients were also reevaluated 11 months from the initial injury, of which 7 were reevaluated again 24 months from the initial injury by MRI. The MR appearance of the treated ACL was categorized into four grades depending on homogeneity, straight band, and size. MR assessment of the ACL after 3 month treatment demonstrated a well defined normal-sized straight band in 37 cases (74%). There was a significant relationship between the 3 and 11 month MR evaluations (r. = 0.801, p < 0.0001). There were also significant relationships between the MR and arthroscopic evaluations (r, = 0.455, p < 0.005) and between the MR and stress radiographic evaluations (r, = 0.348, p < 0.025) after the 3 month treatment. MRI can demonstrate ACL healing when treated conservatively with early protective mobilization. 40 refs., 3 figs., 2 tabs.

    Anterior cruciate ligament (ACL) disruptions are common injuries that currently hold a fearsome reputation among athletes of all abilities and disciplines. Indeed, if the diagnosis is missed at first presentation, it is difficult to attribute ongoing instability and recurrent injury to an ACL tear. Classically, patients then often improve shortly before repeatedly reinjuring their knee. At some point, the knee may lock, necessitating an arthroscopic meniscectomy. Tragically, this then hastens the progression of joint arthrosis and the decline of the joint function. While the burden of responsibility does not lie solely with the junior doctor or the general practitioner, it is often at the first consultation that the natural history of this devastating injury is decided. The ability to recognise, institute early management and reassure patients with ACL tears about the future is an invaluable asset to the non-specialist junior doctor. Once diagnosed, the responsibility of advising and further counselling of patients with ACL injuries is best left to the orthopaedic knee specialist. Family practitioners and emergency room doctors should not feel pressured to offer advice on specialist areas such as return to sports without reconstruction or indeed the need for reconstruction. Indeed, decisions to return to sports with ACL-deficient knees have all too often led to disastrous reinjury events to the articular cartilage and/or the menisci. PMID:21097944

    The Dutch Orthopaedic Association has a long tradition of development of practical clinical guidelines. Here we present the recommendations from the multidisciplinary clinical guideline working group for anterior cruciate ligament injury. The following 8 clinical questions were formulated by a steering group of the Dutch Orthopaedic Association. What is the role of physical examination and additional diagnostic tools? Which patient-related outcome measures should be used? What are the relevant parameters that influence the indication for an ACL reconstruction? Which findings or complaints are predictive of a bad result of an ACL injury treatment? What is the optimal timing for surgery for an ACL injury? What is the outcome of different conservative treatment modalities? Which kind of graft gives the best result in an ACL reconstruction? What is the optimal postoperative treatment concerning rehabilitation, resumption of sports, and physiotherapy? These 8 questions were answered and recommendations were made, using the "Appraisal of Guidelines for Research and Evaluation" instrument. This instrument seeks to improve the quality and effectiveness of clinical practical guidelines by establishing a shared framework to develop, report, and assess. The steering group has also developed 7 internal indicators to aid in measuring and enhancing the quality of the treatment of patients with an ACL injury, for use in a hospital or practice.

    To evaluate main numerical parameters of anterior segment and the effects of eyelid skin changes on these parameters in patients with systemic sclerosis (SSc). Thirty-four patients with SSc and 34 healthy individuals were enrolled. Besides full eye examination, anterior segment measurements including anterior chamber depth (ACD), anterior chamber volume, anterior chamber angle width, central corneal thickness, pupil size, corneal volume and keratometry were obtained using a Sirius Scheimpflug/Placido photography-based topography system. Eyelid thickness was evaluated using the scala of the modified Rodnan skin score and the patients were subgrouped with respect to these scores to evaluate the effect of eyelid thickening on the anterior segment parameters. Age and sex distributions of the groups were similar (p > 0.05). SSc patients had steeper and thinner corneas, smaller corneal volumes, narrower, shallower and smaller anterior segments but only the mean ACD value of right eyes was found significantly less than those of the controls (p = 0.047). The mean ACD values of SSc subgroup patients with moderate to severe eyelid thickening (50 %) had lower ACD measurements compared to those of control group. (p = 0.043 for the right eyes, p = 0.070 for the left eyes). However, SSc subgroup patients with none to mild eyelid thickening (50 %) had similar anterior segment parameters with control subjects (p > 0.05). Anterior chamber parameters of the SSc patients could show significant differences. These differences occur parallel to the eyelid changes but not secondary to it. PMID:26694912

    Background Measurement of anterior segment parameters plays an important role in diagnosis and treatment of glaucoma. 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 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.

    A 55-year-old woman was admitted with a 3 days history of increasing lethargy with bradyphrenia and apathy. She progressively developed severe somnolence with marked abulia, right hemiparesis, right hemianopsia, and pseudobulbar palsy. Brain magnetic resonance imaging showed the rare image of bilateral acute anterior choroidal artery infarction. Pseudobulbar mutism and in rare cases abulia have been described in acute anterior choroidal artery infarction contralateral to an older lesion in mirror position. Although neurologic deterioration is not infrequent in anterior choroidal artery territory infarcts, the absence of focal neurologic signs on admission is rare and did not raise suspicion of acute stroke.

    Full Text Available A 29-year-old woman who underwent laser in situ keratomileusis (LASIK for myopic astigmatism in both eyes presented with severe pain, photophobia and decreased visual acuity in the left eye eight days after surgery. Examination revealed severe anterior uveitis with fibrinous exudates in the anterior chamber, flap edema and epithelial bullae. Laboratory investigations for uveitis were negative and the patient required systemic and intensive topical steroids with cycloplegics to control the inflammation. This case demonstrates that severe anterior uveitis may develop after LASIK and needs prompt and vigorous management for resolution.

  1. Multimodal emotion perception after anterior temporal lobectomy

    Full Text Available In the context of emotion information processing, several studies have demonstrated the involvement of the amygdala in emotion perception, for unimodal and multimodal stimuli. However, it seems that not only the amygdala, but several regions around it, may also play a major role in multimodal emotional integration. In order to investigate the contribution of these regions to multimodal emotion perception, five patients who had undergone unilateral anterior temporal lobe resection were exposed to both unimodal (vocal or visual and audiovisual emotional and neutral stimuli. In a classic paradigm, participants were asked to rate the emotional intensity of angry, fearful, joyful, and neutral stimuli on visual analog scales. Compared with matched controls, patients exhibited impaired categorization of joyful expressions, whether the stimuli were auditory, visual, or audiovisual. Patients confused joyful faces with neutral faces, and joyful prosody with surprise. In the case of fear, unlike matched controls, patients provided lower intensity ratings for visual stimuli than for vocal and audiovisual ones. Fearful faces were frequently confused with surprised ones. When we controlled for lesion size, we no longer observed any overall difference between patients and controls in their ratings of emotional intensity on the target scales. Lesion size had the greatest effect on intensity perceptions and accuracy in the visual modality, irrespective of the type of emotion. These new findings suggest that a damaged amygdala, or a disrupted bundle between the amygdala and the ventral part of the occipital lobe, has a greater impact on emotion perception in the visual modality than it does in either the vocal or audiovisual one. We can surmise that patients are able to use the auditory information contained in multimodal stimuli to compensate for difficulty processing visually conveyed emotion.

  6. 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 The objective of this study is to highlight the possibility of dysphagia induced by anterior cervical osteophytes. When not diagnosed early this condition may be responsible for complications such as severe dysphagia and potential lung aspiration, especially in elderly patients. Analysis of a case report of a 72-year old woman who presented cervical pain and progressive dysphagia. Imaging studies have shown anterior cervical osteophytosis and multilevel degenerative changes in the cervical spine. The patient underwent surgical excision of the cervical anterior osteophytes (C4, C5 and C6 and C5/C6 arthrodesis through anterior approach. The postoperative period was uneventful and symptoms resolved within 2 weeks. Early diagnosis and treatment led to complete resolution, avoiding late and serious complications associated with this pathology in the geriatric population, especially severe and progressive dysphagia and risk of pulmonary aspiration, and the consequent morbidity and mortality associated. A multidisciplinary approach is essential for the correct assessment of this condition

  14. Examination of the sprained ankle: Anterior drawer test or arthrography?

    International Nuclear Information System (INIS)

    The accuracy of the anterior drawer test for the diagnosis of recent lateral ligament tears in the ankle was evaluated in a series of 192 patients using surgical or arthrographic findings for reference. Considerable overlapping of results was obtained in ankles with and without ligament tear. Twenty-eight per cent of the anterior talofibular ligament tears, and 38% of the combined anterior talofibular and calcaneofibular tears were not detected, and single and combined tears could not be differentiated. It is concluded that the anterior drawer test is too unreliable as a basis for any decision regarding surgical treatment of a recent sprain. Therefore, arthrography is recommended as the method of choice in such cases of recent ankle sprain, where the need of surgery has to be supported by X-ray analysis. (orig.)

    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. PMID:26703054

    Full Text Available A 54-year-old male patient presented with acute myocardial infarction involving left anterior descending and right coronary artery territories. Coronary angiogram showed a single coronary artery with right coronary artery arising from left anterior descending artery (LAD, which coursed anterior to right ventricular outflow tract and thrombotic lesion in mid left anterior descending artery before origin of right coronary artery. The patient was treated with thrombolytic therapy and glycoprotein IIb/IIIa inhibitors. Anomalous origin of right coronary artery as a branch of LAD is a very rare type of congenital coronary artery anomalies. It is important to recognize this anomaly as it can be associated with extensive myocardial ischemia and sudden cardiac death in young persons even without atherosclerosis.

    Full Text Available Dirofilariasis is a parasitic infection of the carvivores that may present as a zoonotic infestation in humans. Systemic involvement in man is subcutaneous, pulmonary, or ocular. We report a rare occurrence of ocular dirofilariasis in a 25-year-old male patient who presented with pain and redness in the eye. A live, white, coiled, and highly motile worm was present in the anterior chamber. The worm, however, could not be detected in the anterior chamber, posterior segment, or the angle of the anterior chamber when the patient was taken to the operating room for surgical removal of the worm. The patient was made to lie prone till the worm reappeared in the anterior chamber and was removed by paracentesis. The worm was identified as Dirofilaria repens on the basis of microscopic and histopathological examination.

    2016-01-01

    Minimally invasive approaches are becoming increasingly popular to access the anterior skull base. With interdisciplinary cooperation, in particular endonasal endoscopic approaches have seen an impressive expansion of indications over the past decades. The more recently described transorbital approaches represent minimally invasive alternatives with a differing spectrum of access corridors. The purpose of the present paper is to discuss transorbital approaches to the anterior skull base in the light of the current literature. The transorbital approaches allow excellent exposure of areas that are difficult to reach like the anterior and posterior wall of the frontal sinus; working angles may be more favorable and the paranasal sinus system can be preserved while exposing the skull base. Because of their minimal morbidity and the cosmetically excellent results, the transorbital approaches represent an important addition to established endonasal endoscopic and open approaches to the anterior skull base. Their execution requires an interdisciplinary team approach. PMID:27453759

  5. Anticoagulation after anterior myocardial infarction and the risk of stroke.

    Full Text Available BACKGROUND: Survivors of anterior MI are at increased risk for stroke with predilection to form ventricular thrombus. Commonly patients are discharged on dual antiplatelet therapy. Given the frequency of early coronary reperfusion and risk of bleeding, it remains uncertain whether anticoagulation offers additional utility. We examined the effectiveness of anticoagulation therapy for the prevention of stroke after anterior MI. METHODS AND FINDINGS: We performed a population-based cohort analysis of 10,383 patients who survived hospitalization for an acute MI in Ontario, Canada from April 1, 1999 to March 31, 2001. The primary outcome was four-year ischemic stroke rates compared between anterior and non-anterior MI patients. Risk factors for stroke were assessed by multivariate Cox proportional-hazards analysis. Warfarin use was determined at discharge and followed for 90 days among a subset of patients aged 66 and older (n = 1483. Among the 10,383 patients studied, 2,942 patients survived hospitalization for an anterior MI and 20% were discharged on anticoagulation therapy. Within 4 years, 169 patients (5.7% were admitted with an ischemic stroke, half of which occurred within 1-year post-MI. There was no significant difference in stroke rate between anterior and non-anterior MI patients. The use of warfarin up to 90 days was not associated with stroke protection after anterior MI (hazard ratio [HR], 0.68; 95% confidence interval [CI], 0.37-1.26. The use of angiotensin-converting-enzyme inhibitors (HR, 0.65; 95% CI, 0.44-0.95 and beta-blockers (HR, 0.60; 95% CI, 0.41-0.87 were associated with a significant decrease in stroke risk. There was no significant difference in bleeding-related hospitalizations in patients who used warfarin for up to 90 days post-MI. CONCLUSION: Many practitioners still consider a large anterior-wall MI as high risk for potential LV thrombus formation and stroke. Among a cohort of elderly patients who survived an anterior

    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.

    We describe a patient with ascending tetraparesis following stroke. The patient presented initially with spastic paraparesis which acutely evolved to tetraparesis with abulia. Magnetic resonance imaging revealed acute infarctions in the bilateral medial frontal regions but not in the brainstem or spinal cord. Multiple infarctions in the anterior cerebral artery territory appeared to originate from artery to artery embolism. The present case provides distinct clinical features of anterior cerebral artery syndrome which mimic myelopathy or brainstem lesions. PMID:17903956

  14. Anterior process calcaneal fractures: a systematic evaluation of associated conditions

    International Nuclear Information System (INIS)

    The objective was to evaluate the association, by MRI, of anterior calcaneal process fractures with tarsal coalitions, ankle sprains, and bifurcate ligament abnormalities. A retrospective review of 1,479 foot and ankle MR images was performed, over a period of 5 years, for isolated anterior process fractures of the calcaneus. Fifteen 1.5-T MR examinations were systematically evaluated by two radiologists in consensus. Marrow edema patterns, presence of a calcaneonavicular coalition, as well as bifurcate and anterior talofibular ligaments, were evaluated. There were 15 fractures of the anterior calcaneal process with an incidence of 1%. The average patient age was 51 years (range 25-82). Twelve patients were women and 3 were men. The majority of the fractures (14 out of 15) presented as an edema pattern on T2-weighted images, either diffuse (9 out of 15), or vertical (5 out of 15). One case did not show marrow edema, but rather a hypointense line. Nine patients (60%) demonstrated calcaneonavicular coalition and anterior calcaneal process fracture. In 6 patients (50%) the anterior talofibular ligament (ATFL) was thickened. Three patients did not have axial images, and were classified as non-conclusive for the ATFL evaluation. The bifurcate ligament was thickened with hyperintense signal demonstrating a sprain in 9 out of 13 (69%). Only 2 patients (16.5%) had an anterior calcaneal process fracture without any associated abnormality. We believe that there is a probable association of anterior process fractures and calcaneonavicular coalitions. We also feel, based on our results and the prior literature that there is likely also an association with both ATFL injuries and bifurcate ligament injuries. (orig.)

    For decades spinal surgeons have attempted to design simple, single stage anterior internal fixation systems for the thoracic and lumbar spine. Early devices presented both biomechanical and technical problems. The AO Anterior Thoracolumbar Locking Plate (ATLP) was designed to solve some of the problems encountered with early anterior instrumentation. The ATLP system is constructed in Commercially Pure titanium. It is a low profile device indicated for use for unstable burst fractures in the anterior column; metastatic tumor management; and degenerative diseases of the thoracolumbar spine between levels T10 and L5. Implantation of the device involves direct anterior decompression with sagittal reduction and corpectomy. This is followed by grafting reconstruction, and plate fixation. This device has been implanted in 25 patients with an average follow-up of 38 months. There were five (5) broken screws in three (3) patients, and no broken plates. Implant related postoperative complications included two misplaced screws. Preliminary results indicate that the ATLP system seems to be a safe, low profile, MRI/CT compatible device that provides definitive single stage fixation of the anterior spinal column. PMID:9160452

  8. Anterior, posterior, left anterior oblique, and geometric mean views in gastric emptying studies using a glucose solution

    International Nuclear Information System (INIS)

    Previous research has shown that the single anterior view of the stomach overestimates the gastric half-emptying time of a solid meal compared to the geometric mean of the anterior and posterior views. Little research has been performed comparing the various views of gastric emptying of a glucose solution. After an overnight fast, 49 nondiabetic subjects were given a 450 ml solution containing 50 g of glucose and 200 μCi of technetium-99m sulfur colloid. Sequential 1-min anterior, posterior, and left anterior oblique views were obtained every 15 min. The mean percent solution remaining in the stomach for all three views differed from the geometric mean by 1.9% or less at all time points. Average gastric half-emptying times were: geometric mean, 62.7±3.3 min; anterior, 61.9±3.2 min; posterior, 63.5±3.5 min; and left anterior oblique, 61.6±3.3 min. These half-emptying times were not statistically different. For individual patients, differences between all three views and the geometric mean were not clinically important. Approximately 95% of all patients are expected to have gastric half-emptying times measured by any of the three single views within 17 min of the gastric half-emptying time obtained using the geometric mean. The imaging of gastric emptying using glucose solutions can be performed using a convenient single view which allows continuous dynamic imaging. (orig.)

  9. Humeral avulsion of the anterior shoulder stabilizing structures after anterior shoulder dislocation: demonstration by MRI and MR arthrography

    International Nuclear Information System (INIS)

    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

In 1959 the treated samples were compared against the control by the triangular test; in 1960, in a lattice square 3x3 with four replications. The insecticides applied to the soil in 1959 were as fallows: BHC (gamma-isomer, Heptaclor, Aldrin, Parathion, and Lindane. BHC induced a very strong mold-like «rmusty» off-flavor, significant in relation to the control at the 1% level. Parathion and Lindane induced an unidentified off

    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.)

    Full Text Available En las áreas costeras del norte de Chile es común encontrar en el agua para consumo humano niveles medios o altos de arsénico. La exposición al arsénico puede ir asociada a efectos agudos o crónicos. El objetivo de esta investigación fue determinar el daño histológico que provoca el trióxido de arsénico a nivel de los compartimentos del timo de ratas Sprague-Dawley. Se utilizaron 24 ratas de ambos sexos de 55 días de vida. Las ratas fueron pesadas y divididas en 3 grupos (4 hembras y 4 machos. A los grupos tratados se les aplicó 5 mg y 10 mg de As2O3 respectivamente, en dosis única diaria vía intraperitoneal por 15 días. Al grupo control se le aplicó agua destilada sin arsénico. Después del tratamiento los animales fueron sacrificados y retirado el timo de ellos, los cuales fueron lavados, pesados y seccionados en dos, luego se fijaron en formol tamponado al 10%. Mediante técnica histológica convencional se obtuvieron 4 muestras seriadas de cada timo, de 5 µm de espesor y separadas por 100 µm entre si, luego fueron teñidas con H-E. Se analizaron 30 campos (120 campos por órgano. Los resultados muestran que el As2O3 provoca la pérdida de celularidad en ambos compartimentos del timo, tanto en la corteza como en la médula, viéndose más afectado el compartimento medular (junto a la unión corticomedular. Se observó una reducción significativa del tamaño de la zona medular en ambos grupos tratados (5 y 10 mg de As2O3 respectivamente, siendo probablemente la disminución de este tejido el responsable de la atrofia del timo. Además se observó un aumento del tamaño de la corteza en las ratas hembras tratadas con 10 mg de As2O3. La unión corticomedular de las ratas tratadas se observó difusa o difícil de distinguir.In coastal areas of northern Chile medium or high levels of arsenic are commonly found in drinking water.

  18. Ophthalmohelioses and peripheral light focusing by the anterior eye

    1994-07-01

    A coincidence of the locations of foci of scattered light in the anterior eye with the usual locations of common sun-related eye conditions has been observed. These phenomena may explain the pathogenesis of pterygium and the initial location of certain cortical lens opacities and eyelid malignancies. Human and bovine eyes were used to demonstrate that the anterior eye acts as a side-on lens system. Light incident at the temporal limbus can be concentrated at the nasal limbus or beyond or at the nasal crystalline lens equator. The main pathways of light are transcameral and this is demonstrated by the use of baffles. Although this phenomenon is obvious with visible light, focusing of light at 308nm can be demonstrated. Computer-assisted optical ray tracing in a standard human anterior segment model showed that the peak intensity at the distal limbus is approximately twenty times that of the incident light intensity. The degree of limbal focusing is determined by corneal shape and anterior chamber depth. Such light focusing may be particularly injurious to corneal and lenticular epithelial stem cells. These observations provide circumstantial evidence that peripheral refraction phenomena are involved in the pathogenesis of the anterior ophthalmohelioses. Adequate lateral protection of the eye from increasing ultraviolet insolation may be prudent.

    Full Text Available Background: In multilevel spinal cord compression caused by cervical spondylosis, surgeonsface the choice of performing a posterior route as a laminectomy orlaminoplasty, or an anterior route as multiple adjacent interbody decompressionsor corpectomies. The anterior cervical operation is not considered bysome clinicians because of concerns about complications and the complexityof multilevel anterior cervical surgery.Methods: In this retrospective study, 14 patients with multilevel cervical spondylosiswho were operated on via an anterior route were enrolled to evaluate thecomplexity, safety, and clinical results. The collected parameters were operationtime, blood loss, hospital days, and early and late complications forevaluating the operative complexity, radiographic follow-up for evaluatingfusion, graft problems, implants problems, and the recovery rate using theJapanese Orthopaedic Association score (JOA score for evaluating the operativeresults.Results: The mean operation time was 363.4 min, and blood loss was 431.4 ml. Anearly complication was noted in 1 patient with combined deep vein thrombosisand a pulmonary embolism. Late complications were screw breakage in1 patient and screw loosening in 5 patients. The mean duration of follow-upwas 21.9 months. The mean recovery rate of the JOA score was 38.8% postoperativelyand 51.9% at the final follow-up. The fusion rate was 100% inthis series.Conclusions: Anterior cervical decompression and fusion for multilevel stenosis requires alonger operation time than posterior procedures; however, the clinical resultsare satisfactory.

    Full Text Available Two female patients with histories of cancer who showed cryptogenic organizing pneumonia (COP complications and bilateral anterior uveitis with hypopyon were examined. Both patients had suffered from COP and received intermitted systemic corticosteroid administration (SCA. The first patient, a 65-year-old woman with a history of breast cancer, showed bilateral uveitis with hypopyon. The topical corticosteroid treatment was ineffective. After SCA for the treatment of COP was started, the hypopyon gradually dissipated. Upon termination of SCA, uveitis relapses were controlled by renewed SCA. The other patient, a 69-year-old woman with a history of ovarian cancer, showed bilateral anterior uveitis with hypopyon. Her intraocular outcome did not improve by the topical corticosteroid administration, but SCA that was applied to treat COP led to remission of uveitis. Imaging examinations, biochemical analysis, symptoms or HLA-B27 antigen screenings in either patient did not explain the development of uveitis. Bilateral anterior uveitis is commonly related to autoimmune disease or systemic syndrome. We report two cases with COP that developed bilateral anterior uveitis with hypopyon resistant to topical administration but responsive to systemic administration of corticosteroid. These findings suggest that COP can be associated with the etiology of anterior uveitis.

    Acute anterior uveitis (AAU) is the commonest type of uveitis and HLA-B27 AAU is the most frequently recognized type of acute anterior uveitis and anterior uveitis overall. Recent evidence indicates that acute anterior uveitis is a heterogenous disease, is polygenic and is frequently associated with the spondyloarthropathies (SpA). Studies of patients with AAU and animal models of disease indicate a role for innate immunity, the IL-23 cytokine pathway and exogenous factors, in the pathogenesis of both SpA and acute anterior uveitis. Recently described genetic associations cluster around immunologic pathways, including the IL-17 and IL-23 pathways, antigen processing and presentation, and lymphocyte development and activation. Patients with ankylosing spondylitis (AS) and AAU share other genetic markers, such as ERAP-1, which show strong evidence of gene-gene interaction and point to new mechanisms of disease pathogenesis. These observations have major implications for understanding the pathogenesis of HLA-B27 diseases, such as AAU, and may lead to the development of more specific therapy for AAU.

    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.

    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.

    2011-01-01

    No study reports the histological features of the various zone of the anterior tubercle of the tibia in the different stages of the Osgood-Schlatter (O-S) lesion. For this reason we carried on an histological study. Specimens were taken from 13 patients with O-S lesion prior to surgery. In 4 cases in the apophyseal stage lesions were present in an altered fibrocartilage anterior to the ossification centre. In 9 cases in the epiphyseal stage varying degrees of reparative tissues were observed in the bed of the fragment of the secondary ossification centre. In 3 of them a zone of lesion was observed within the fibrocartilage anterior to the ossification centre. These results suggest that the slippage of the patellar tendon insertion may be progressive and caused by pathological fibrocartilage. PMID:21669134

    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.

    Martín-Loeches, Manuel; Muñoz, Francisco; Casado, Pilar; Melcón, A; Fernández-Frías, C

    2005-09-01

    Anterior negativities obtained when a grammatical rule is violated may reflect highly automatic first-pass parsing processes, the detection of a morphosyntactic mismatch, and/or the inability to assign the incoming word to the current phrase structure. However, for some theorists these negativities rather reflect some aspect of working memory processes. Event-related brain potentials (ERPs) obtained for word category and morphosyntactic violations were directly compared with effects obtained when working memory is particularly demanded (embedding subject- or object-relative clauses), yielding a significant dissociation in terms of topography. Even though, the anterior negativities for grammatical violations vanished when relative clauses were embedded, suggesting that the processes reflected by anterior negativities related to grammatical violations and those related to working memory manipulations, even if different, are placing demands on a common pool of limited resources.

    Full Text Available Doença de Bowen designa carcinoma in situ cuja evolução é lenta e progressiva, geralmente assintomática. Na região perianal essa lesão é pouco freqüente, ocorrendo mais em indivíduos jovens. Quando acomete áreas que não sofreram exposição solar, outros fatores podem estar associados, como HPV, doenças inflamatórias ou neoplasias de cólon. A doença pode ser tratada com cirurgia convencional, criocirurgia ou terapia fotodinâmica. O objetivo é relatar um raro caso clínico da doença de Bowen, em paciente do sexo feminino, jovem, negra, que apresentava uma extensa lesão na região perianal com positividade para HPV. A paciente estava em tratamento para retocolite ulcerativa com suspeita de ter, associadamente, doença de Crohn. Foi tratada com criocirurgia e evoluiu com boa cicatrização do local, sem apresentar sinais de recidiva 34 meses após o tratamento.Bowen's disease is generally an asymptomatic in situ carcinoma that develops slowly. It rarely occurs in the genital region and mainly affects young persons. Skin lesions occurring in areas not exposed to sunlight may be associated with other factors, like HPV, inflammatory disease or colon neoplasia. The disease may be treated by conventional surgery, cryosurgery or photodynamic therapy. The aim is to present the clinical characteristics of a rare case of Bowen's disease in a young, black female, who had a large lesion in the perianal region, which tested positive for HPV. The woman had been undergoing treatment for intestinal ulcerative rectocolitis or Crohn's disease. She was treated with cryosurgery and there was no sign of recurrence during the ensuing 34 months.

    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.

    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 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.

    We documented the spacing and distribution of perikymata on the buccal enamel surface of fossil hominin anterior teeth with reference to a sample of modern human and modern great ape teeth. A sample of 27 anterior teeth attributed to Australopithecus (5 to A. afarensis, 22 to A. africanus) and of 33 attributed to Paranthropus (6 to P. boisei, and 27 to P. robustus) were replicated and sputter-coated with gold to enable reflected light microscopy of their surface topography. Anterior teeth were then divided into 10 equal divisions of buccal crown height. The total perikymata count in each division of crown height was recorded using a binocular microscope fitted with a vernier micrometer eyepiece. Then the mean number of perikymata per millimeter was calculated for each division. Similar comparative data for a modern sample of 115 unworn human anterior teeth and 30 African great ape anterior teeth were collected from ground sections. Perikymata counts in each taxon (together with either known or presumed periodicities of perikymata) were then used to estimate enamel formation times in each division of crown height, for all anterior tooth types combined. The distributions of these estimates of time taken to form each division of crown height follow the same trends as the actual perikymata counts and differ between taxa in the same basic way. The distinction between modern African great apes and fossil hominins is particularly clear. Finally, we calculated crown formation times for each anterior tooth type by summing cuspal and lateral enamel formation times. Estimates of average crown formation times in australopiths are shorter than those calculated for both modern human and African great ape anterior teeth. The data presented here provide a better basis for exploring differences in perikymata spacing and distribution among fossil hominins, and provide the first opportunity to describe four specimens attributed to Homo in this context. Preliminary data indicate that

    There is sparse information concerning approaches to metachronous lung cancer in patients who had a previous pneumonectomy for lung carcinoma. We describe the case of a 55-year-old woman who underwent a left pneumonectomy for lung carcinoma. Four years later, a radiological examination revealed a hypermetabolic nodule in the right upper lobe, which was located in the left hemithorax because of right lung hyperinflation and a mediastinal shift to the left. Wedge resection was carried out through a left anterior mediastinotomy. We believe that an anterior mediastinotomy represents a valuable option for the management of recurrent lung cancer after previous surgery. PMID:26124429

    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. In this Opinion article, we capitalize on new findings from functional neuroimaging to propose a model that links high-level cognitive functions to specific structures within the anterior hippocampus.

    Injury to the axillary artery is a rare complication of anterior shoulder dislocation. Open surgical repair is technically demanding because of the anatomical position of the vessel and the propensity for concomitant injuries. Standard surgical exposure techniques involve extensive dissection, including a combination of supraclavicular or infraclavicular incision, median sternotomy, and thoracotomy causing significant morbidity and mortality rates. Endovascular techniques may offer an alternative to these surgically demanding procedures. We present a patient with a traumatic dissection of the axillary artery following anterior shoulder dislocation who was successfully managed with an endovascular stent. PMID:18411587

    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.

  15. Clearance from the anterior chamber of RBCs from human diabetics

    International Nuclear Information System (INIS)

    Erythrocytes from diabetic patients manifest decreased deformability and increased adherence. These abnormal membrane properties may diminish the ability of erythrocytes (RBCs) from diabetics to undergo deformation in passage through the trabecular meshwork. Using sodium chromate Cr 51-labeled RBCs from type I diabetic patients with proliferative retinopathy and normal control subjects, we studied RBC clearance from the rabbit anterior chamber. The mean time for 50% clearance (T50) of RBCs from diabetics (76 hours) was significantly longer than that for RBCs from normal subjects (19.5 hours). In this model, RBCs from diabetics have a slower clearance from the anterior chamber than do RBCs from normal subjects

Freqüentemente a ocorrência de tombamento de mudas, em pré ou pós-emergência, afetam os cronogramas de plantio, acarretando a morte de milhares de plântulas. 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%. A elevada densidade de semeadura (50g/m² e a ocorrência de tempo húmido e chuvoso parecem ter concorrido grandemente para a severa incidência do tombamento.

    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.

    The purpose of this work is the clinical commissioning of a recently developed in vivo range verification system (IRVS) for treatment of prostate cancer by anterior and anterior oblique proton beams. The IRVS is designed to perform a complete workflow for pre-treatment range verification and adjustment. It contains specifically designed dosimetry and electronic hardware and a specific software for workflow control with database connection to the treatment and imaging systems. An essential part of the IRVS system is an array of Si-diode detectors, designed to be mounted to the endorectal water balloon routinely used for prostate immobilization. The diodes can measure dose rate as function of time from which the water equivalent path length (WEPL) and the dose received are extracted. The former is used for pre-treatment beam range verification and correction, if necessary, while the latter is to monitor the dose delivered to patient rectum during the treatment and serves as an additional verification. The entire IRVS workflow was tested for anterior and 30 degree inclined proton beam in both solid water and anthropomorphic pelvic phantoms, with the measured WEPL and rectal doses compared to the treatment plan. Gafchromic films were also used for measurement of the rectal dose and compared to IRVS results. The WEPL measurement accuracy was in the order of 1 mm and after beam range correction, the dose received by the rectal wall were 1.6% and 0.4% from treatment planning, respectively, for the anterior and anterior oblique field. We believe the implementation of IRVS would make the treatment of prostate with anterior proton beams more accurate and reliable.

    Anterior urethral valves are a rare congenital anomaly associated with distal urethral obstruction, which can result in a poor prognosis. We report on the endoscopic creation of a fetal urethrotomy for obstructive uropathy resulting from anterior urethral valves. A 33-year-old woman was evaluated at 17 weeks gestation due to fetal megacystis. The diagnosis of anterior urethral valves was confirmed by the characteristic sonographic feature of a dilated membranous penile urethra. Oligohydramnios with normal-appearing kidneys and favorable urinary electrolytes led to fetal intervention. Ablation on the ventral site of the fetal penis for a cutaneous urethrotomy was performed using a YAG laser under a 1-mm fetoscope at 19 weeks gestation. Urine was drained from the incision and the dilated penis and the distended bladder shrunk with an increase in amniotic fluid. However, the fetus died unexpectedly on postoperative day 3, and chorioamnionitis was suspected as the etiology. While the outcome was unfavorable, our preliminary experience shows that fetal urethrotomy for obstructive uropathy can be achieved in utero using an endoscopic laser approach. Further experience will be required to evaluate the therapeutic value of this new procedure in the management of fetal anterior urethral valves. PMID:18648205

    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 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.

    The human anterior cingulate cortex is distinguished by the presence of an unusual cell type, a large spindle neuron in layer Vb. This cell has been noted numerous times in the historical literature but has not been studied with modern neuroanatomic techniques. For instance, details regarding the neuronal class to which these cells belong and regarding their precise distribution along both ventrodorsal and anteroposterior axes of the cingulate gyrus are still lacking. In the present study, morphological features and the anatomic distribution of this cell type were studied using computer-assisted mapping and immunocytochemical techniques. Spindle neurons are restricted to the subfields of the anterior cingulate cortex (Brodmann's area 24), exhibiting a greater density in anterior portions of this area than in posterior portions, and tapering off in the transition zone between anterior and posterior cingulate cortex. Furthermore, a majority of the spindle cells at any level is located in subarea 24b on the gyral surface. Immunocytochemical analysis revealed that the neurofilament protein triple was present in a large percentage of these neurons and that they did not contain calcium-binding proteins. Injections of the carbocyanine dye DiI into the cingulum bundle revealed that these cells are projection neurons. Finally, spindle cells were consistently affected in Alzheimer's disease cases, with an overall loss of about 60%. Taken together, these observations indicate that the spindle cells of the human cingulate cortex represent a morphological subpopulation of pyramidal neurons whose restricted distribution may be associated with functionally distinct areas.

    2016-02-01

    The anterior fixation of the anterior process of the malleus has been studied in a number of Cetartiodactyla. This anterior process, also known as processus gracilis, is provided by the prearticular (gonial), a dermal bone, whereas the cartilage of Meckel becomes resorbed in perinatal ontogenetic stages. Posteriorly, the prearticular fuses with the cartilaginous caput of the malleus; rostrally, the prearticular (= processus gracilis) is always fixed to the anterior crus of the ectotympanic by an extremely thin splint (thickness fused to the adjacent bones already in juveniles. However, in ruminants, the tegmen tympani tends to disappear and the processus internus praearticularis appears as relatively small bony knob at the floor of the medial cranial cavity, and it seems not to be fused to the surrounding bones; in later age stages, it may become secondarily overgrown by the petrosal. This dorsally exposed processus internus praearticularis seems to be a synapomorphy of the Ruminantia. The functional meaning of this internal process of the prearticular, which is also developed to a minor degree in Carnivora, remains unclear at the moment - but we present some speculations about this.

    Wernicke's aphasia occurs after a stroke to classical language comprehension regions in the left temporoparietal cortex. Consequently, auditory-verbal comprehension is significantly impaired in Wernicke's aphasia but the capacity to comprehend visually presented materials (written words and pictures) is partially spared. This study used functional magnetic resonance imaging to investigate the neural basis of written word and picture semantic processing in Wernicke's aphasia, with the wider aim of examining how the semantic system is altered after damage to the classical comprehension regions. Twelve participants with chronic Wernicke's aphasia and 12 control participants performed semantic animate-inanimate judgements and a visual height judgement baseline task. Whole brain and region of interest analysis in Wernicke's aphasia and control participants found that semantic judgements were underpinned by activation in the ventral and anterior temporal lobes bilaterally. The Wernicke's aphasia group displayed an 'over-activation' in comparison with control participants, indicating that anterior temporal lobe regions become increasingly influential following reduction in posterior semantic resources. Semantic processing of written words in Wernicke's aphasia was additionally supported by recruitment of the right anterior superior temporal lobe, a region previously associated with recovery from auditory-verbal comprehension impairments. Overall, the results provide support for models in which the anterior temporal lobes are crucial for multimodal semantic processing and that these regions may be accessed without support from classic posterior comprehension regions.

    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

  8. MR imaging of anterior cruciate ligament injury: associated findings

    International Nuclear Information System (INIS)

    Authors investigated the associated findings and their value in the diagnosis of anterior cruciate ligament (ACL) injury in MR image. The knee MR images of 47 patients with ACL injury (complete;24, partial;23) and 61 patients with normal ACL confirmed by the knee arthroscopy or operation were reviewed retrospectively. The degree of anterior translocation of tibia and the degree of posterior cruciate ligament (PCL) buckling were evaluated. The prevalence and pattern of associated adjacent bone, ligament and meniscus injuries were studied. The means(± 2 standard errors) of anterior translocation were different significantly in statistical analysis (ρ < 0.001, student t-test) between injury group (7.51 ± 1.16 mm) and normal group (-0.56 ± 0.92mm). In the level of 5mm of anterior translocation for the criteria of ACL injury, the sensitivity, specificity, accuracy were 78.7%, 89.5%, 84.3% for each. The means of PCL buckling ratio were also different statistically between injury group(0.23 ± 0.02) and normal group(0.17 ± 0.01)(ρ < 0.001). In the level of 0.20 for diagnostic criteria of ACL injury, the sensitivity, specificity, accuracy were 71.4%, 83.6%, 78.4% for each. Thirty one medial meniscus tear (66%), thirteen lateral meniscus tear (28%), ten medial collateral ligament injury (28%), one PCL injury(2%) were associated with ACL injury. The twenty nine bone marrow changes were found in twenty patients (43%) which included acutely injured seven patients. In acute cases, the bone marrow changes were depicted as diffuse or focal high signal intensity lesions in lateral femoral or tibial condyles in contrast to the changes in chronic cases depicted as focal low signal intensity lesions in variable location. Lateral femoral condylar notch depression were found in nine patients (19%) and avulsion fractures of anterior tibial spine in four patients(9%).

    Different clinical tests have been suggested in the literature as significant indicators of anterior shoulder instability. Sometimes patients with recurrent anterior shoulder instability may show some muscular guarding thus making the evaluation of specific clinical tests very difficult. These patients may also report a medical history with posterior shoulder pain that can be also elicited during some clinical manoeuvres. From September 2005 to September 2006 we prospectively studied patients who underwent an arthroscopic anterior capsuloplasty. Shoulder clinical examination was performed including anterior shoulder instability tests (drawer, apprehension and relocation tests). Furthermore the exam was focused on the presence of scapular dyskinesia and posterior shoulder pain. The patients were also evaluated with ASES, Rowe, SST (Simple Shoulder Test), Constant and UCLA (University of California at Los Angeles) scoring system preoperatively and at the latest follow-up time. In the period of this study we observed 16 patients treated for anterior gleno-humeral arthroscopic stabilisation, who preoperatively complained also of a posterior scapular pain. The pain was referred at the level of lower trapezium and upper rhomboids tendon insertion on the medial border of the scapula. It was also reproducible upon local palpation by the examiner. Four of these patients also referred pain in the region of the insertion of the infraspinatus and teres minor. After arthroscopic stabilisation the shoulder was immobilised in a sling with the arm in the neutral rotation for a period of 4 weeks. A single physician supervised shoulder rehabilitation. After a mean time of 6.8 months of follow-up, all the shoulder scores were significantly improved and, moreover, at the same time the patients referred the disappearance of the posterior pain. Posterior scapular shoulder pain seems to be another complaint and sign that can be found in patients affected by anterior shoulder instability

    Full Text Available Objetivou-se avaliar a progressão da doença e o dano oxidativo em cabras com anemia e doença respiratória mediante aplicação de ferro parenteral. Foram estudadas seis cabras, adultas, com parâmetros eritrocitários indicativos e anemia e manifestações de doença respiratória (tosse, espirros e secreção nasal. O grupo controle foi composto por seis cabras adultas, sadias. As cabras de ambos os grupos após serem submetidos à avaliação clínica receberam dose similar (0,5g de hidróxido férrico em complexo dextrânico, por via intramuscular. Amostras de sangue colhidas com EDTA, antes da aplicação do ferro e 48 horas depois foram utilizadas para determinação da concentração de substâncias reativas ao ácido tiobarbitúrico (TBARS. Nas cabras doentes antes da aplicação do ferro os valores de TBARS foram equivalentes aos valores mensurados nos controles antes e após a aplicação do ferro (p>0,05. Os valores mensurados nas cabras doentes foram muito mais elevados (p<0,001 no mesmo grupo de animais depois da aplicação do ferro e nos controles antes e após a aplicação. A aplicação do ferro agravou a condição clinica dos animais com doença respiratória, sendo evidenciada uma condição de toxidade refletida pelo estresse oxidativo. Assim sendo, não se deve recomendar tal suplementação nos caprinos acometidos de doenças do aparelho respiratório.

    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.

    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 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.

  17. Treatment of ruptured anterior communicating artery aneurysms with GDCs

    International Nuclear Information System (INIS)

    Objective: To summarize 45 cases of ruptured anterior communicating artery aneurysms treated with GDCs. Methods: All aneurysms were embolized with GDCs. Results: Complete embolization was achieved in 25 aneurysms, subtotal in 14, and partial in 6. Two cases were cured by the second time embolization. One case of recurrent aneurysm after G DC treatment was curved by surgical clipping. Brain infarction was noted in 7 cases after the endovascular procedure, and one of them died of pneumonia, another one remained in permanent coma. 1-20 months follow up showed stable result. 4 of 5 cases with multi-intracranial aneurysms had been treated with on of this procedure. Conclusions: The result of endo vascular treatment of anterior communicating artery aneurysms in the early period after rupture was good. Although there was a relatively high risk of local brain infarction, the clinical outcome was satisfactory

    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.

  19. Missing Screw as a Rare Complication of Anterior Cervical Instrumentation

    2013-01-01

    Full Text Available Although anterior cervical arthrodesis is an effective procedure for the treatment of cervical disorders, the method has some complications. Here, we describe this rare complication of cervical instrumentation with a literature review. A 23-year-old male patient was operated for a C6-C7 dislocation. At postoperative month 10, he presented with hemoptysis and dysphagia. Cervical roentgenograms showed anterior migrations of one broken screw and a plate-locking screw at the C6 corpus. One screw was missing. We concluded that the missing screw had perforated the esophagus and had been eliminated spontaneously through the gastrointestinal tract. No screw should migrate. Even loose screws should be noted in follow-up X-ray studies. If such findings are detected, a second operation for revision should be considered as soon as possible to prevent potentially fatal complications.

    Full Text Available OBJECTIVE: The autors report a case of a traumatic rupture of the tibialis anterior tendon (TTA that was early diagnosed and treated in the emergency service. This is a rare clinical entity with few cases reported in the literature. CASE REPORT: A 66-year old female presented at the emergency service complaining about pain at the anterior aspect of her ankle and inability to walk normally, after a fall. Physical examination revealed clinical signs for TTA rupture, which was later confirmed by ultrasound. Surgical treatment was performed immediately â€" the tendon was anchored into the medial cuneiform with a soft tissue-to-bone anchor. The follow-up revealed good functional result. CONCLUSION: Physical examination and a high index of suspicion are important when facing a patient who had sustained an ankle trauma. The TTA rupture is a diagnosis to consider because unrecognized ruptures led to important functional deficits and poor functional results.

    The serratus anterior plane block has been described for analgesia of the hemithorax. This study was conducted to determine the spread of injectate and investigate the anatomical basis of the block. Ultrasound-guided serratus anterior plane block was performed on six soft-fix embalmed cadavers. All cadavers received bilateral injections, on one side performed with 20 ml latex and on the other with 20 ml methylene blue. Subsequent dissection explored the extent of spread and nerve involvement. Photographs were taken throughout dissection. The intercostal nerves were involved on three occasions with dye, but not with latex. The lateral cutaneous branches of the intercostal nerve contained dye and latex on all occasions. The serratus plane block appears to be mediated through blockade of the lateral cutaneous branches of the intercostal nerves. Anatomically, serratus plane block does not appear to be equivalent to paravertebral block for rib fracture analgesia. PMID:27440171

  2. MR for assessing anterior cruciate ligament reconstructions by tendon grafts

    International Nuclear Information System (INIS)

    150 patients were examined via magnetic resonance (MR) after anterior cruciate (ACL) ligament reconstruction (76 patellar tendon grafts, 53 semitendinosous tendon grafts and 21 sutures). The results of MR were compared with clinical tests (Lachman, pivot-shift and anterior drawer test), in 2 cases with the operative findings, and in one case with arthroscopy findings. In 91% of patients with a clinically stable knee we found a continuous low-intensity ligamental structure. 10 patients were examined twice or more between 8 days and 6 months after surgery. Ligamental structures of low signal intensity did not significantly change their MR characteristics. MR is a valuable noninvasive method for evaluating ligament reconstructions. (orig./GDG)

    Full Text Available Autism spectrum disorders (ASDs comprise a heterogeneous set of neurodevelopmental disorders characterized by dramatic impairments of interpersonal behavior, communication, and empathy. Recent neuroimaging studies suggested that ASD are disorders characterized by widespread abnormalities involving distributed brain network, though clear evidence of differences in large-scale brain network interactions underlying the cognitive and behavioral symptoms of ASD are still lacking. Consistent findings of anterior insula cortex hypoactivation and dysconnectivity during tasks related to emotional and social processing indicates its dysfunctional role in ASD. In parallel, increasing evidence showed that successful control of anterior insula activity can be attained using real-time fMRI paradigms. More importantly, successful regulation of this region was associated with changes in behavior and brain connectivity in both healthy individuals and psychiatric patients. Building on these results we here propose and discuss the use of real-time fMRI neurofeedback in ASD aiming at improving emotional and social behavior.

    1992-01-01

    Three patients developed signs of a unilateral cervical cord lesion 6 to 36 h after the acute onset of severe cervico-brachial pain. The neurological deficit progressed over 6 to 18 h. On the painful side a central Horner's syndrome, a hemiparesis with plegia of the hand, and a slight pallhypaesthesia were found. On the opposite side thermhypaesthesia and hypalgesia were noted with a level at the dermatome C5 or C6. T2-weighted MR images revealed in one patient a small area of increased signal intensity restricted to one half of the cervical cord, and electromyography in another patient showed after 6 months evidence of segmental chronic denervation. Both abnormalities were found at the clinically expected level. The findings are consistent with a small infarction of the cervical cord in the perfusion territory of a central (sulco-commissural) artery, a duplicated anterior spinal artery or an anterior spinal branch of the vertebral artery.

    Twenty mongrel dogs received 6000 rads of irradiation to the rectum and colon using the Nominal Standard Dosage Equation. Three weeks after irradiation each dog underwent anterior resection of the rectosigmoid with reconstruction randomized to either an EEA stapled or a two layer handsewn anastomosis. Each dog was studied digitally and by barium enema at the time of surgery, on the seventh postoperative day, and at autopsy. Five clinically significant leaks and three radiographic leaks occurred in the EEA stapled anastomoses. The handsewn anastomoses had five clinically significant leaks and two radiographic leaks. The data indicate that low anterior resection with either an EEA stapled or handsewn anastomosis cannot be done safely after 6000 rad preoperative irradiation.

    We describe the technique and results of the endovascular treatment of anterior cranial fossa dural arteriovenous fistulas (DAVF) in four symptomatic patients. Catheterization was via the superior sagittal sinus in two patients and via the ophthalmic artery in two patients. Embolization was performed using detachable platinum coils in the former two patients and a liquid embolic system (Onyx-18, MTI) in the latter. We were able to reach the fistula site and to embolize the arteriovenous shunting zone in all of the patients. The final angiogram showed complete occlusion of the DAVFs, and all patients recovered completely. No complications related to either approach were observed. Endovascular treatment of anterior cranial fossa DAVFs is feasible by either transvenous or transarterial access. (orig.)

    The anterior tarsal tunnel syndrome is a rare entrapment neuropathy of the deep peroneal nerve beneath the inferior extensor retinaculum of the ankle. It is frequently unrecognized and may lead to misdiagnosis and delayed treatment. We report the case of a 77 year old patient complaining of symptoms of an anterior tarsal tunnel syndrome with neuropathic pain located at the dorsal part of the foot, without any sensorimotor loss. The ENMG was in favour of a motor impairment of the deep peroneal nerve. MRI exploration of the ankle showed a millimetric bony overgrowth of the upper pole of the navicular bone, irritative to the deep peroneal nerve. Infiltration at overgrowth of the navicular provided a partial and temporary decrease in pain symptoms. Surgical nerve decompression was then considered. PMID:26376569

    Meningiomas are the most common form of primary intracranial tumors. If the anterior visual pathways are affected clinical visual compromise, visual field defects, oculomotor nerve disturbances or propotosis are predominant. Meningiomas of the anterior visual pathway remain therapeutically challenging due to the direct anatomical relationship to the circulus arteriosus cerebri, the cavernous sinus and cranial nerves. The therapy of choice is microsurgical resection. In many cases a curative approach can be achieved with modern surgical techniques and simultaneously maintaining patient quality of life. Problematic are cases in which resection would be associated with the risk of clinical impairment and in these cases radiotherapy is an important therapeutic option. In cases involving complex invasiveness an interdisciplinary treatment to control local clinical symptoms is favored. PMID:23604251

    Electrolytic lesions were made in the anterior hypothalamus of 8 prepubertal female rhesus monkeys, aged 1.1-1.7 years. Six unoperated females served as controls. No effects were found of the lesions upon age and body weight at menarche or at first ovulation, as estimated by blood levels of progesterone and laparoscopic observations. From these findings it appears that the neural control of puberty in the female rhesus may not be exerted through the anterior hypothalamus, in contrast with the rat and ferret. Further, an attempt was made to identify biometric correlates of hormonal changes during puberty. Firstly, the well known dip in growth rate, about 0.4 years before menarche, was observed. Secondly, there was a marked spurt in growth of the nipples starting at 0.2 years before menarche. The close temporal association between accelerated nipple growth and menarche suggests that both of these developmental characteristics result from changes in (presumably ovarian) steroid hormone secretion.

    Full Text Available One third of patients with antiepileptic-resistant temporal lobe epilepsy (TLE will have to undergo surgery for a better seizure control. Anterior temporal lobectomy (ATL is done for mesial temporal sclerosis that is the most common histopathological lesion associated with TLE. Psychiatric manifestations following ATL are not uncommon with depressive symptoms more common with left ATL and manic symptoms following right ATL. Mr. A is a 42-year-old left cerebral dominant (Confirmed by WADA test male with no past history of psychiatric illness who had undergone anterior temporal lobectomy with amygdalohippocampectomy. He started having manic episodes post operatively which subsided with antipsychotics. He had multiple such episodes over the next 13 years with minimal inter episodic symptoms. This is a rare instance of manic symptoms following left-sided ATL that emphasizes the need for better understanding of the cerebral laterality of affective symptoms.

    A series of 377 consecutive patients were operated upon with low anterior resection for rectal cancer in the nine Danish departments of surgical gastroenterology during 1992-1993. A retrospective analysis was carried out to calculate the frequency of anastomotic leakage and to evaluate factors of...... a higher leakage rate (p = 0.02), whereas departments with a low number of rectal cancer surgeons had a low rate of anastomotic leakage (p = 0.02). In conclusion, the rather high frequency of anastomotic leakage calls for further clinical and pathogenetic research in this field. Until then, we...... recommend the routine use of a peroperative leakage test and selective use of prophylactic ostomy in cases of unsatisfactory anastomosis. Furthermore, it is recommended that low anterior resection for rectal cancer is limited to few surgeons in each department in order to ensure a uniform quality and...

  19. Radiographic evaluation of anterior dislocation of the shoulder

    International Nuclear Information System (INIS)

    To establish radiographic criteria to choose the most appropriate technique of reduction for each type of anterior glenohumeral dislocation, and to determine the type of dislocation which requires general anesthesia. Material and Methods: Radiography in two different projections was performed in 67 patients with antero-inferior shoulder dislocations before a reduction attempt. The method proposed by Boss-Holzach-Matter was used as the primary technique for all shoulder dislocations. Results: Most subcoracoid dislocations (84.4%) could be reduced by the Boss-Holzach-Matter method while only a few subglenoid dislocations (15.8%) were reducible by this technique. Displaced associated fractures significantly reduced the success rate of the reduction attempts. Conclusion: Anterior dislocations of the shoulder require different methods of reduction depending upon the type (sub-group) of dislocation. Reduction of subglenoid dislocations with associated greater tuberosity fracture should be performed under general anesthesia to avoid head-splitting fracture

    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.

    2011-10-01

    Indentation and histological analysis of the porcine iris were done to assess the relative stiffness of the anterior (stroma) and posterior (dilator and sphincter) layers. The dimensions of the constituent structures were documented histologically by staining with a monoclonal anti-human α-smooth muscle actin antibody to determine the location of the stroma, sphincter, and dilator. Intact porcine irides (4-8 h post-mortem) were bisected into two equal C-shaped halves to indent both surfaces. Indentation experiments were performed using a 1 mm cylindrical indenter tip. The load-displacement curve for each experiment was used to estimate effective instantaneous and equilibrium moduli for the anterior and posterior surfaces of the tissue. A total of 18 irides (9 pairs) with 3-5 indentations per iris surface was performed. The average thickness of the samples was 550 μm; the indentation depth was limited to 60-100 μm depending on the thickness of the sample at each point. Posterior surface indentation gave larger forces than anterior, with the resulting instantaneous modulus of 6.0 ± 0.6 kPa versus 4.0 ± 0.5 kPa (mean ± 95% CI, n = 45, p poroelasticity, we conclude that the posterior components of the iris - dilator, pigment epithelium, and sphincter - are on average stiffer than the stroma and anterior border layer.

    Introduction The anterior petrosectomy is a well-defined skull base approach to lesions such as petroclival meningiomas, posterior circulation aneurysms, petrous apex lesions (chondrosarcomas, cholesteatomas), ventrolateral brainstem lesions, clival chordomas, trigeminal neurinomas, and access to cranial nerves III, IV, V, and VII. Methods and Materials Fourteen anterior petrosectomies on eight cadaveric heads were performed in a skull base dissection laboratory. Predissection and postdissection thin-cut computed tomography scans were obtained to compare the bone resection. A computer program was used (InVivo5, Anatomage, San Jose, California, United States) to measure the bone resection and the improved viewing angle. Results The average bone removed in each plane was as follows: anterior to posterior plane was 10.57 mm ± 2.00 mm, superior to inferior was 9.39 mm ± 1.67 mm, and lateral to medial was 17.46 mm ± 4.64 mm. The average increased angle of view was 13.01 ± 2.35 degrees (Table 1). The average volume was 1786.94 ± 827.40 mm(3). Conclusions Anterior petrosectomy is a useful approach to access the ventrolateral brainstem region. We present a cadaveric study quantitating the volume of bone resection and improvement in the viewing angle. These data provide useful preoperative information on the utility of this skull base approach and the gain in the viewing angle after bony removal. PMID:27175319

    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

  2. 3D spectral imaging system for anterior chamber metrology

    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.

    2008-01-01

    Full Text Available AbstractBackground and Purpose: Anterior shoulder dislocation is the most common major joint dislocation. In most cases, this dislocation is being relocated in emergency departments. Routinely, pre and post reduction radiographs are performed. This study was done to determine the necessity of radiographs in the emergency department for management of patients with suspected anterior shoulder dislocation.Materials and Methods: In this case series study, 116 patients suspected of anterior shoulder dislocation were referred to Hazrat Rasoul Akram and Haftome Tir Hospitals emergency departments in Tehran, and were investigated for a one year period. The emergency physicians evaluated and documented the possibility of dislocation or relocation, before obtaining radiographs. Outcome measures were the assessment of joint positions on the x-rays by an orthopedic surgeon.Results: 84 cases (72% were male and 32 cases (28% were female. Mean age of the patients was 31.5±8.5 yrs. Thirty (30 patients had recurrent dislocations without traumatic mechanism (group 1 and eighty six (86 patients had no prior dislocation or a blunt mechanism of injury (group 2. The accuracy of the emergency physician’s assessment in dislocations was 100% in group 1 and 98% in group 2. False assessments occurred only in patients with fractures. There is no significant difference between emergency physicians and orthopedic surgeons in the assessment of dislocations and relocations, when the emergency physicians did accuralty diagnose them.Conclusion: Our study showed that the physicians are highly accurate in clinical determination of anterior shoulder dislocation and relocation. Pre-reduction films should be obtained when the mechanism of injury is trauma. Post-reduction films should be obtained in fracture-dislocations or when the physicians are uncertain of correct relocation.

    Full Text Available Background: Although ultrasound (US has a wide range of applications in orthopedic diagnostics, sonographic evaluation of traumatic anterior cruciate ligament (ACL insufficiency is still inadequate. There is a growing need for diagnostic tests that allow for simple and reliable assessment of ACL instability. This investigation aims to evaluate feasibility of sonographic technique for diagnosing complete ACL insufficiency. Materials and Methods: Eighty three consecutive patients suspected of ACL injury were examined with sonographic, dynamic test of anterior instability. The translation of the intercondylar eminence against the patellar tendon was measured in the injured and opposite (injured knee. Subsequent magnetic resonance imaging was performed on all patients. Forty-seven of them underwent a further arthroscopy. Five patients have been examined for the 2 nd time to evaluate interclass and intraclass agreement and bias. Results: Complete ACL insufficiency has been confirmed in 37 patients. In those individuals, the total anterior knee translation and the difference between two joints (side-to-side difference were significantly increased (8.67 mm standard deviation [SD] 2.65 mm in the affected knee versus 2.88 mm SD 1.26 mm in uninjured joint; P < 0.001. Based on a threshold of 2.0 mm for the side-to-side difference and 5.0 mm for the absolute translation, the sonographic test was found to have a sensitivity and specificity of 91.9% and 95.6%, respectively. Conclusions: The present technique supports the clinician with additional fast and noninvasive diagnostic procedure that can facilitate the evaluation of anterior knee instability.

    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 s...

    Osteogenesis imperfecta (OI) is an inherited condition in which defects in type 1 collagen cause abnormalities in many tissues and organs, including bone, teeth, heart valves, and eyes. We describe a 6-month-old boy with OI who presented with anterior megalophthalmos of the right eye and infantile-onset glaucoma of the left eye. To our knowledge, this is the first reported case of these types of congenital eye anomalies in an infant with OI. PMID:26994503
