    Full Text Available La pielonefritis enfisematosa es una forma poco común de infección renal, caracterizada por la presencia de bacterias coliformes productoras de gas que afecta preferentemente a los pacientes diabéticos. Comunicamos el caso de una mujer diabética de 57 años de edad que ingresó en el hospital por un shock séptico, signos de pielonefritis enfisematosa aguda bilateral y cetoacidosis diabética. En los cultivos de las muestras de orina y sangre desarrolló Escherichia coli. La paciente fue tratada exitosamente con antibióticos de amplio espectro por un tiempo prolongado, control diabético y medidas de sostén solamente. No fue necesario el drenaje con catéteres o la nefrectomía para superar esta situación potencialmente letal.Emphysematous pyelonephritis is a rare form of kidney infection characterized by the presence of gas-forming coliform bacteria which affects more frequently diabetic subjects. We report the case of a 57-years-old diabetic woman, who was admitted in septic shock, signs of acute bilateral emphysematous pyelonephritis, and diabetic ketoacidosis. Both blood and urine cultures yielded Escherichia coli. The patient was successfully treated using long-term broad-spectrum antibiotics, diabetic control and supportive measures alone. Catheter drainage and nephrectomy were not necessary to overcome this life threatening situation.

    Full Text Available A mímica facial é fundamental para a expressão e comunicação humana, que são possíveis apenas através da integridade do nervo facial. Sendo assim, a paralisia facial periférica (PFP pode deixar seqüelas estéticas, funcionais e psicológicas. A causa mais comum é a paralisia de Bell (50 a 80%, onde a maioria dos pacientes apresenta manifestação unilateral. O acometimento bilateral simultâneo é raro, sendo a leucemia a neoplasia que com maior freqüência pode resultar nesse tipo de manifestação. A seguir, relatamos o caso de um paciente de dezoito anos de idade apresentando leucemia linfóide aguda (LLA e PFP simultânea, ambas refratárias ao tratamento quimioterápico, culminando com o óbito cinco meses após o início da PFP. Realizou-se considerações importantes sobre a fisiopatologia da PFP na LLA, além de uma revisão da literatura.The facial mimic is very important to the human expression and communication, which depend on the integrity of the facial nerve. So, the peripheric facial palsy (PFP can leave esthetics, functional and psychological sequelae. The more common etiology is Bell's palsy (50 to 80% and most of the patients show a unilateral manifestation. The simultaneous bilateral PFP is rare, and the leukemia is the neoplasia that can often that kind of manifestation. We present a clinical case of an 18-year-old patient with acute lymphoid leukemia and simultaneous bilateral facial palsy, who did not recover after the chemotherapy treatment, and died five months after the initial manifestation of the facial palsy. Important considerations were accomplished about the physiopathology of PFP in acute lymphoid leukemia, besides literature review.

    Full Text Available La epidermólisis bulosa comprende un grupo heterogéneo de enfermedades ampollosas de la piel y mucosas de origen congénito y hereditario. El tratamiento es insatisfactorio en gran parte, por lo cual son necesarias ciertas medidas para proteger al paciente y evitar la aparición de dichas lesiones y sus complicaciones. Se describe el manejo anestesiológico en un niño de 3 años de edad, al que se le administró anestesia general intravenosa con clorhidrato de ketamina y diazepán, y se describen todos los cuidados y recomendaciones que hay que tener para evitar especialmente los roces, las presiones y las temperaturas altas.Epidermolysis bullosa is a heterogenous group of ampullary diseases of the skin and mucosas of congenital and hereditary origin. The treatment is largely unsatisfactory, and that´s why it is necessary to take some measures to protect the patient and to prevent the appareance of such lesions and their complications. It is described the anesthetic management of a 3-year-old child that was administered intravenous general anesthesia with ketamine hydrochlorate and diazepam. The care and recommendations that should be taken into account to avoid touches, pressures and high temperatures, are described.

Se estudió mediante mamografía, ultrasonido (US y resonancia magnética (RM, y el diagnóstico anatomopatológico final fue una recaída de la enfermedad de base por compromiso mamario. El caso resulta de interés, ya que se trata de una forma de manifestación muy poco habitual, con escasos reportes en la literatura y ningún trabajo encontrado en el que se describa la utilidad de la resonancia magnética en estos pacientes.We report a case of a 26-year-old girl with acute lymphoblastic leukemia treated with chemotherapy and bone marrow transplant who presented with palpable lumps in both breasts. Mammography, ultrasound and magnetic resonance imaging were performed, with the final pathological diagnosis being relapse of her underlying disease with breast involvement.

    2014-05-01

    Full Text Available La Meningitis Bacteriana Aguda (MBA de adquisición comunitaria es una enfermedad prevalente en todo el mundo; constituye siempre una emergencia médica y se asocia a una alta morbimortalidad. Su epidemiología es variable y los principales agentes en adultos son S. pneumoniae, N. meningitidis, H. influenzae y L. monocitogenes. En Chile existe un sistema de vigilancia recientemente implementado que permitirá un mejor diagnóstico epidemiológico. Las manifestaciones clínicas clásicas no siempre están presentes principalmente en adultos mayores. El diagnóstico requiere del estudio de líquido cefalorraquídeo, y las técnicas de biología molecular han significado un aporte relevante en los últimos años. El tratamiento antibiótico debe ser instaurado rápidamente para mejorar el pronóstico, mientras que la terapia coadyuvante con corticoides en adultos tiene sólo beneficios en etiología neumocócica. Se requieren mejores estrategias de prevención frente a una entidad que no ha cambiado su mortalidad a pesar del progreso de la medicina moderna.

    Full Text Available Acute dacryoadenitis is an uncommon condition that involves inflammation of the lacrimal gland. In rare instances, dacryoadenitis may be bilateral. A delay in proper treatment of an otherwise simple case of dacryoadenitis may lead to significant soft tissue morbidity such as cellulitis, lacrimal gland abscess, or orbital abscess. We report the case of a 24-year-old male who presented to the emergency department with acute bilateral dacryoadenitis. The patient′s symptoms did not respond to oral antibiotics and he subsequently required admission for intravenous antibiotics. During his hospitalization the patient had diagnostic testing to try to determine the etiology for his symptoms. The unique aspects of managing a case of bilateral dacryoadenitis as well as treatment recommendations are discussed in this case report.

    Full Text Available Introducción: las intoxicaciones han sido en los últimos años una importante causa de aumento de la morbilidad y mortalidad en edades pediátricas. Objetivo: determinar el comportamiento clínico de las intoxicaciones agudas en la etapa de enero de 2005 a diciembre de 2009 en el Hospital Pediátrico "William Soler". Métodos: el estudio se realizó en el Hospital "William Soler". Se revisaron las historias clínicas, los registros de intoxicaciones agudas y las tarjetas de codificación de egresos hospitalarios por intoxicaciones de los pacientes llegados al hospital en esta etapa. Resultados: se recibieron en el hospital 886 pacientes. El grupo de mayor frecuencia de intoxicaciones fue el de 1 a 5 años, con predominio del sexo masculino, aunque sin diferencias significativas con respecto al sexo femenino. Las intoxicaciones más frecuentes fueron por medicamentos, fundamentalmente psicofármacos y antibióticos, seguido por alimentos y por productos químicos del hogar. El 30,2 % de los casos fueron ingresados. Conclusiones: estos resultados nos hacen pensar en la necesidad de estar alertas y crear acciones encaminadas a proteger o evitar las intoxicaciones en edades tan vulnerables.

    Full Text Available RESUMEN:La insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina. Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia.En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal. SUMMARYAcute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one.In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels.

Paciente do sexo feminino, 27 anos, tinha aumento agudo da glândula lacrimal, bilateral, com sinais flogísticos. As alterações tomográficas e laboratoriais confirmaram o diagnóstico e o tratamento com esteróide sistêmico foi introduzido, com resolução completa dos sinais e sintomas. COMENTÁRIOS: A dacrioadenite é uma apresentação incomum da mononucleose infecciosa e pode minimizar outras manifestações desta doença. O diagnóstico de mononucleose deve ser considerado em casos de dacrioadenite aguda bilateral. Os esteróides sistêmicos contribuem para a resolução do quadro inflamatório.The authors present a rare case of acute bilateral dacryoadenitis in association with infectious mononucleosis. A 27 year-old woman had acute bilateral lacrimal gland enlargement with inflammatory signs. The CT scan findings and laboratorial investigations confirmed the diagnosis of infectious mononucleosis. The systemic treatment with intravenous steroids was initiated leading to complete remission of the signs and symptoms. COMMENTS: Dacryoadenitis is an uncommon manifestation of infectious mononucleosis and may minimize other signs of the disease. Mononucleosis has to be considered in acute dacryoadenitis cases. Systemic steroids contribute to the fast regression of inflammatory condition.

    Shoulder dislocations are the most common major joint dislocations encountered in the emergency departments. Bilateral shoulder dislocations are rare and of these, bilateral posterior shoulder dislocations are more prevalent than bilateral anterior shoulder dislocations. Bilateral anterior shoulder dislocation is very rare. We present a case of 24-year-old male who sustained bilateral anterior shoulder dislocation following minor trauma, with associated greater tuberosity fracture on one side. Prompt closed reduction followed by immobilization in arm sling and subsequent rehabilitation ensured a good outcome. PMID:24082765

    Bilateral facial paralysis is an unusual clinical entity that occurs in less than 1% of patients with facial paralysis. In children bilateral facial paralysis is even more rare, and establishing its etiology can be challenging. Four pediatric patients ranging in age from 3 to 17 years are presented who developed bilateral facial paralysis as a result of acute otitis media, Lyme disease, recurrent central nervous system leukemia, and acute disseminated encephalomyelitis. The diagnosis and treatment of pediatric bilateral facial paralysis are reviewed, as well as the pertinent literature.

    Full Text Available Bilateral subclavian steal syndrome is a rare condition. It is usually due to reversal of vertebral blood flow in the setting of bilateral proximal subclavian or left subclavian plus innominate artery severe stenosis or occlusion. This finding may cause cerebral ischemia related to upper extremities exercise.

    Full Text Available A creatinina continua a ser o padrão laboratorial para diagnóstico da injúria renal aguda (IRA. Esforços para prevenção da nefrotoxicidade foram prejudicados pelo atraso no diagnóstico da IRA por critérios utilizando somente a creatinina como marcador, havendo, por isso, grande interesse em identificar mais precocemente biomarcadores confiáveis. Além disso, o tratamento precoce da IRA pode ser correlacionado com um melhor prognóstico e a identificação de biomarcadores para um diagnóstico precoce pode melhorar a eficácia de estratégia terapêutica. Portanto, torna-se imperativo encontrar biomarcadores que possam estratificar corretamente o grau de lesão renal e o risco de desenvolver doença renal crônica (DRC.

Macroscopicamente, as adrenais estavam redondas e com volume e aumentados. Ao corte elas eram friáveis, vermelho-amarronzadas, intercaladas por áreas branco-amareladas levemente proeminentes. Histologicamente, extensas áreas do parênquima continham adipócitos bem diferenciados, células hematopoéticas e macrófagos com hemossiderina, achados característicos de mielolipoma adrenal.A case of bilateral adrenal myelolipoma in a 13-year-old female Poodle is reported. Acute septic peritonitis due to intestinal ulceration and perforation caused by a linear foreign body was the cause of death. The adrenal neoplasm was an incidental necropsy finding. The adrenal glands were grossly rounded, enlarged and friable, and had red-brownish parenchyma interwoven by slightly prominent white-yellowish foci. Histologically, the findings of differentiated adipocytes in large areas of the parenchyma, in association to hematopoietic cells and macrophages with hemosiderin were consistent with the diagnosis of adrenal myelolipoma.

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present.

    Full Text Available Supernumerary teeth are a rare finding in dental arch, which are mostly reported in association with syndromes. However, they can be seen in the absence of systemic disease. They may be single, multiple, unilateral, or bilateral with a predilection for the mandible, especially in nonsyndromic patients. Due to its different form and position in dental arch, it is observed to be associated with various periodontal problems. This case report presents a case of bilateral parapremolars in the maxillary arch in a nonsyndromic patient, which led to food lodgment and consequently led to caries and periodontal problem on the left maxillary arch.

    1992-12-01

    Patients with bilateral urolithiasis diagnosed at their first visit were followed for at least one year after the start of treatment. In this retrospective study of 123 patients, the basic metabolic workup revealed no specific underlying cause of simultaneously occurring bilateral nephrolithiasis, and none of the currently used therapeutic regimes proved to be efficient in attaining clinically acceptable stone-free rates at the 3, 6 and 12-month follow-ups. Of 38 patients treated with extracorporeal shockwave lithotripsy (SWL), 21 underwent treatment of both kidneys and 10 (48%) were free of stones bilaterally after 12 months. All of the 17 patients treated with unilateral SWL failed to achieve a stone-free state on the contralateral side. In another group, treated with medication alone to minimize risks of stone recurrence, only 3 of 26 (11.5%) patients were stone-free on both sides 12 months after the start of medication. Since we achieved a stone-free state of both kidneys in no more than 12% of the non-medicated cases, it seems warranted to treat bilateral urolithiasis with SWL more frequently, particularly when patients cannot return regularly to the stone clinic for a longterm follow-up.

  12. Bilateral tuberculate supernumerary teeth.

    Science.gov (United States)

    Eigbobo, Joycelyn Odegua; Osagbemiro, Babatope Bamidele

    2011-05-16

    Supernumerary teeth are teeth in excess of the normal series occurring in any region of the dental arch. They are located mostly in the anterior maxillary region and are classified according to their location and morphology. The tuberculate type of supernumerary tooth possesses more than one cusp or tubercle (barrel shaped). It is rare to find bilateral tuberculate supernumerary teeth in the premaxillary region and when found they rarely erupt. This report describes a 13-year-old boy with erupted palatally placed bilateral tuberculate supernumerary teeth. The presence of these supernumerary teeth led to the labial displacement and rotations of the anterior maxillary teeth. The treatment involved extraction of the supernumerary teeth and a referral for orthodontic management of the crowding, displacement and rotations. The occurrence of erupted palatally placed tuberculate anterior teeth in this case is a rare experience. However, the associated orthodontic problems are within familiar spectrum.

    Full Text Available A leptospirose é a zoonose mais importante do mundo. Os pacientes são tipicamente homens jovens. Vários fatores estão envolvidos na insuficiência renal aguda (IRA na leptospirose, incluindo ação nefrotóxica direta da leptospira, hiperbilirrubinemia, rabdomiólise e hipovolemia. Os principais achados histológicos são nefrite intersticial aguda e necrose tubular aguda. A IRA na leptospirose é geralmente não oligúrica e hipocalêmica. Alterações da função tubular precedem a queda na taxa de filtração glomerular, o que poderia explicar a alta frequência de hipocalemia. O tratamento antibiótico é eficaz nas fases precoces e tardias e/ou graves. Para pacientes críticos com IRA na leptospirose, as seguintes condutas são recomendadas: hemodiálise precoce e diária; baixa infusão de volume (devido ao risco de hemorragia pulmonar, e estratégias de proteção pulmonar. A mortalidade na IRA associada à leptospirose está em torno de 22%.

    Tercio De Campos

    Full Text Available De acordo com a Classificação de Atlanta a pancreatite aguda pode ser dividida, baseado em sua severidade, em uma forma leve ou grave. Uma série de aspectos têm sido discutidos nos últimos anos, tais como, quantas categorias de gravidade devem ser consideradas; se o doente com falência orgânica é igual ao doente com necrose infectada; qual o papel da falência orgânica transitória; e como avaliar a falência orgânica. A reunião de revista"Telemedicina Baseada em Evidência - Cirurgia do Trauma e Emergência" (TBE-CiTE realizou uma avaliação crítica de artigos relacionados a este tema, considerando três artigos recentes que delinearam duas grandes revisões publicadas nos últimos meses. Estes artigos sugerem a classificação de gravidade em três ou quatro categorias, ao invés de pancreatite aguda leve ou grave, além de discutir qual o melhor escore para avaliar a falência orgânica. As seguintes recomendações foram propostas: (1 A pancreatite aguda deve ser classificada em quatro categorias: leve, moderada, grave e crítica, o que permite uma melhor determinação das características dos doentes; (2 Avaliação de falência orgânica com um escore de gravidade, preferencialmente algum que avalie diretamente cada falência orgânica, tais como o SOFA e o MODS (Marshall. O SOFA parece ter maior acurácia, mas o MODS tem melhor aplicabilidade devido à facilidade de uso.

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    The public authorities have recently approved the building of a Littoral Station in Aguda, a small fishing village on the Atlantic coast, 15 km south of the River Douro estuary in the municipal area of Vila Nova de Gaia. The internal structure of the building involves a Fishery Museum exhibiting ancient and modern gear, a Public Aquarium displaying the local marine fauna and flora and a Research and Educational Department for marine biology, aquaculture and fishery. The project was drawn up by the architect João Paulo Peixoto, in collaboration with local engineers, and the author. In Aguda there is an active, small-scale fishery, based on traditional methods handed down from generation to generation. The almost unstudied local marine fauna and flora is characterized by a high diversity of invertebrates and a rich abundance of fish stocks. Easy access to a variety of marine biotopes is guaranteed by means of the local fishing-fleet, thus supporting the Station's programme of education and research.

    Full Text Available A pancreatite aguda tem sido alvo de grandes discussões que vão desde o entendimento de sua fisiopatologia até a investigação de novas modalidades terapêuticas. Reconhece-se que a necrose pancreática e a falência orgânica múltipla - mormente associadas à infecção - representam os principais fatores determinantes da evolução para o óbito, mas, apesar dos grandes avanços em seu estudo, a doença permanece como um desafio para o clínico e o cirurgião. Deste modo, um melhor conhecimento dos mecanismos envolvidos em sua fisiopatologia pode ser a chave para um tratamento mais eficaz, principalmente em relação às formas graves, cuja letalidade ainda encontra-se substancialmente elevada. Baseado nestas considerações, o presente trabalho tem por objetivo a revisão bibliográfica da fisiopatologia, dos fatores patogênicos envolvidos na história natural da pancreatite aguda grave e dos eventos associados à síndrome da resposta inflamatória sistêmica e à sepse, esboçando-se assim o mosaico patogênico desta importante condição.

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    Full Text Available A model of acute schistosomiasis of the mouse was used to observe whether curative treatment would be followed by an enhancement of the hepatic and splenic lesions, as a consequence of the massive destruction of worms and eggs within the portal system. Mice infected with 50 cercariae of Schistosoma mansoni were treated with both oxamniquine and praziquantel on the 50th day of infection and submitted to a sequential histologic examination from the 2nd to the 45th day after treatment. Although severe focal lesions due to dead and disintegranting worms were present in the livers of the treated animals, no aggravation of the general changes (reative hepatitis and splenitis, or periovular granulomas was seen in comparison with a control non-treated group. Of 50 animals treated during the acute phase of schistosomiasis only one died espontaneously, while 16 ou of 30 infected controls died before the end of the experiment. The present investigation indicates that curative treatment during the acute phase of schistosomiasis does not enhance previous lesions at first and results in progressive disappearance of the lesions starting six days following chemotherapy.Foi utilizado um modelo de esquistossomose aguda do camundongo para testar se o tratamentop curativo da parasitose nesta fase poderia produzir uma exacerbação das lesões hepáticas e esplênicas, em virtude da destruição maciça de vermes e ovos nointerior do sistema porta.

    Entre los años 2007 y 2009, varios estudios epidemiológicos sobre la Insuficiencia Renal Aguda (IRA, mostraron que la enfermedad tiene características clínicas y pronóstico distinto y más severo que los considerados previamente. Otras investigaciones, realizadas entre los años 2010 y 2014, confirmaron y extendieron esos hallazgos. Tomados en conjunto y con la perspectiva de los estudios posteriores, el resultado de los iniciales ha cambiado los paradigmas de la In- suficiencia Renal Aguda y el manejo de los pacientes. Los estudios más recientes sugieren que el pronóstico de la enfermedad puede estar mejorando, posiblemente como consecuencia del mejor manejo de la enfermedad.

    A CHANGE IN THE PARADIGMS OF THE ACUTE RENAL FAILURE

    ABSTRACT

    Between the years of 2007 and 2009 several epidemiologic studies on Acute Renal Failure showed that the disease has clinical features and prognosis different from the predominating beliefs at the time. Rather than having a benign prognosis after recovery, Acute Renal Failure has a high mortality and a guarded prognosis, with frequent development of progressive chro- nic Kidney Disease and the need for maintenance hemodialysis after apparent recovery. The recommendation was made that these patients be closely followed by a nehrologist after leaving the Hospital. Several other studies between 2010 and 2014 confirmed and extended these findings. Taken as a whole, and with the added information of later publications, these studies have changed the paradigm of Acute Renal failure and the management of patients with that disease. The most recent studies suggest that the disease prognosis may be improving, in part at least as a consequence of the better and more insightful management of the disease.

    Full Text Available La faringoamigdalitis aguda (FAA en el adulto es una de las enfermedades infecciosas más comunes en la consulta del médico de familia. La etiología más frecuente es viral. Dentro de la etiología bacteriana, el principal agente responsable es Streptococcus pyogenes o estreptococo β-hemolítico del grupo A (EBHGA, causante del 5-30% de los casos. En el manejo diagnóstico, las escalas de valoración clínica para predecir la posible etiología bacteriana, son una buena ayuda para seleccionar a qué pacientes se deben practicar las técnicas de detección rápida de antígeno estreptocócico. Es conocido que, en general, sin estas técnicas se tiende al sobrediagnóstico de FAA estreptocócica, con la consiguiente prescripción innecesaria de antibióticos, muchas veces de amplio espectro. Así, con el manejo de las escalas y la técnica de diagnóstico rápido, elaboramos los algoritmos de manejo de la FAA. Los objetivos del tratamiento son acelerar la resolución de los síntomas, reducir el tiempo de contagio y prevenir las complicaciones supurativas locales y no supurativas. Los antibióticos de elección para el tratamiento de la FAA estreptocócica son penicilina y amoxicilina. La asociación de amoxicilina y clavulánico no está indicada en el tratamiento inicial en la infección aguda. Los macrólidos tampoco son un tratamiento de primera elección; su uso debe reservarse para pacientes con alergia a la penicilina. Es importante en nuestro país adecuar tanto el diagnóstico de la FAA bacteriana y la prescripción de antibióticos a la evidencia científica disponible. La implantación de protocolos de actuación en las farmacias comunitarias puede ser de utilidad para identificar y cribar los casos que no requieran tratamiento antibiótico.

    OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012. Univariate and multivariate analyses were performed to determine the relationship between retreatment of bCSDH and clinical, radiological, and surgical variables. RESULTS Two hundred ninety-one patients with bCSDH were identified, and 264 of them underwent unilateral (136 patients) or bilateral (128 patients) surgery. The overall retreatment rate was 21.6% (57 of 264 patients). Cases treated with unilateral surgery had twice the risk of retreatment compared with cases undergoing bilateral surgery (28.7% vs 14.1%, respectively, p = 0.002). In accordance with previous studies, the data also showed that a separated hematoma density and the absence of postoperative drainage were independent predictors of retreatment. CONCLUSIONS In bCSDHs bilateral surgical intervention significantly lowers the risk of retreatment compared with unilateral intervention and should be considered when choosing a surgical procedure.

    Bilateral hemifacial spasm (BHS) is a rare focal movement disorder often associated with vascular compression of both facial nerves. The contractions are usually asymmetric and asynchronous. Typically, one side is affected first and there is a long but variable interval for the symptoms on the other side to occur. BHS must be differentiated from other conditions including blefarospasm, facial myokymia, facial tics, oromandibular dystonia, and hemimasticatory spasm. The most successful and non-invasive symtomatic treatment is botulinum toxin injections but microvascular decompression surgery is another therapeutic option. We report the case of a 70 years old man with bilateral hemifacial spasms and present a brief review of the literature.

    Full Text Available Apresentamos 6 casos de meningoencefalite aguda por sarampo, diagnosticados durante epidemia na cidade de São Paulo, em 1997. Os prontuários dos 6 pacientes foram analisados retrospectivamente. O diagnóstico de meningoencefalite baseou-se nas alterações clínicas e liquóricas, e foi confirmado por sorologia específica. Dos 467 pacientes com sarampo atendidos no Instituto de Infectologia Emílio Ribas nesse período, estes 6 evoluíram com alterações neurológicas e liquóricas durante a fase exantemática, sendo a sonolência e rigidez de nuca os achados mais frequentes. Os pacientes tinham entre 2 meses e 28 anos de idade. O exame do líquor mostrou pleocitose em todos. Não houve correlação entre a severidade do quadro clínico e liquórico com a evolução. Em 4 casos foi necessária internação na unidade de terapia intensiva; destes, 2 foram intubados. Apenas 2 pacientes apresentaram alterações na tomografia computadorizada de crânio. Todos tiveram boa evolução, sem sequelas.

    Full Text Available A síndrome aguda do tórax (SAT acomete portadores de anemia falciforme e é responsável por cerca de 25% dos óbitos. Relata-se o caso de um homem pardo de 45 anos, alcoolista crônico, sem nenhum antecedente de falcização, com quadro de pneumonia-símile havia sete dias. A radiografia simples do tórax mostrou infiltrado heterogêneo bilateral, com áreas de consolidação e broncograma aéreo e derrame pleural à esquerda. Outros exames laboratoriais revelaram anemia, leucocitose com desvio à esquerda e hipoxemia. Tratado com cefoxitina e amicacina, o paciente evoluiu rapidamente para insuficiência respiratória aguda e morreu 14 horas após a internação. Na necropsia, no exame dos pulmões observaram-se intensa congestão, hemorragia intra-alveolar, dano alveolar difuso e hemácias com morfologia falciforme. O caráter rápido, progressivo e freqüentemente mimetizado por outras doenças torna a SAT um evento dramático e de diagnóstico precoce difícil, sendo, entretanto, obrigatória tê-la sempre em mente, especialmente em um país com grande população da raça negra como o Brasil.

    Full Text Available A Injúria Renal Aguda (IRA é cada vez mais prevalente nos países desenvolvidos e nos em desenvolvimento, e está associada com morbidade e mortalidade severas. A maioria das causas da IRA pode ser evitada por meio de intervenções em nível individual, comunitário, regional e intra-hospitalar. Medidas efetivas devem incluir, em toda a comunidade, os esforços para aumentar a consciência dos efeitos devastadores do IRA e fornecer orientações sobre as estratégias de prevenção, bem como o reconhecimento e tratamento precoces. Os esforços devem ser focados em minimizar as causas de IRA, aumentando a consciência da importância de medidas seriadas de creatinina sérica em pacientes de alto risco para IRA, e documentar o volume de urina em pessoas gravemente doentes para obtenção de diagnóstico precoce; até o momento, não há ainda um papel definitivo para outros biomarcadores. Há a necessidade de protocolos para sistematizar a conduta em condições de IRA pré-renal e em infecções específicas. Dados mais precisos sobre a verdadeira incidência e o impacto clínico da IRA ajudarão a melhor conhecer a importância desta doença, a aumentar o conhecimento de IRA por parte dos governantes, dos médicos em geral e de outros profissionais de saúde para ajudar na prevenção da doença. A prevenção é a chave para evitar a pesado ônus de mortalidade e morbidade associada com IRA.

Ocorre epidemicamente nos meses de outono e inverno. Algumas populações de crianças (recém-nascidos pré-termo, cardiopatia congênita, doença pulmonar crônica, imunocomprometidos, desnutridos, entre outros apresentam maior risco de morbidade e mortalidade. Os vírus multiplicam-se nas células epiteliais ciliadas, e a inflamação e os debris celulares ocasionam obstrução da via aérea, hiperinsuflação, atelectasia localizada, chiado e alterações das trocas gasosas. Não existem evidências definitivas em relação aos tratamentos utilizados para esta doença. O tratamento inclui a utilização de oxigênio, hidratação, beta-2 agonistas por via inalatória, epinefrina racêmica, DNase recombinante, fisioterapia respiratória, entre outros. Medidas profiláticas: administração de anticorpos monoclonais (palivizumab. A maioria das crianças com BA, independentemente da gravidade da doença, recuperam-se sem seqüelas. O curso natural desta doença, habitualmente, varia entre sete a dez dias, mas algumas crianças permanecem doentes por semanas.

    Full Text Available OBJECTIVE: To evaluate the efficacy and safety of bilateral pallidotomies in five patients with generalized dystonia. BACKGROUND: Generalized dystonias are frequently a therapeutic challenge, with poor responses to pharmacological treatment. GPi (globus pallidus internus pallidotomies for Parkinson's disease ameliorate all kinds of dyskinesias/dystonia, and recent studies reported a marked improvement of refractory dystonias with this procedure. METHODS: Five patients with generalized dystonias refractory to medical treatment were selected; one posttraumatic and four idiopathic. The decision to perform bilateral procedures was based on the predominant axial involvement in these patients. Dystonia severity was assessed with the Burke-Fahn-Marsden Dystonia Scale (BFM. Simultaneous procedures were performed in all but one patient, who had a staged procedure. They were reevaluated with the same scale (BFM by an unblinded rater at 1, 2, 3, 30, 60, 90, 120 and 180 days post-operatively. RESULTS: The four patients with idiopathic dystonia showed a progressive improvement up to three months; the patient with posttraumatic dystonia relapsed at three months. One patient had a marked improvement, being able to discontinue all the medications. A mean decrease in the BFM scores of 52,58% was noted. One patient had a trans-operative motor seizure followed by a transient hemiparesis secondary to rack hemorrhage; other was lethargic up to three days after the procedure. CONCLUSIONS: Our results show that bilateral GPi pallidotomies may be a safe and effective approach to medically refractory generalized dystonias; it can also be speculated that the posttraumatic subgroup may not benefit with this procedure.As distonias generalizadas são freqüentemente um desafio terapêutico, com pobres respostas aos tratamentos farmacológicos.

  19. Compensation following bilateral vestibular damage

    Bill J Yates

    2011-12-01

    Full Text Available Bilateral loss of vestibular inputs affects far fewer patients than unilateral inner ear damage, and thus has been understudied. In both animal subjects and human patients, bilateral vestibular hypofunction (BVH produces a variety of clinical problems, including impaired balance control, inability to maintain stable blood pressure during postural changes, difficulty in visual targeting of images, and disturbances in spatial memory and navigational performance. Experiments in animals have shown that nonlabyrinthine inputs to the vestibular nuclei are rapidly amplified following the onset of BVH, which may explain the recovery of postural stability and orthostatic tolerance that occurs within 10 days. However, the loss of the vestibulo-ocular reflex and degraded spatial cognition appear to be permanent in animals with BVH. Current concepts of the compensatory mechanisms in humans with BVH are largely inferential, as there is a lack of data from patients early in the disease process. Translation of animal studies of compensation for BVH into therapeutic strategies and subsequent application in the clinic is the most likely route to improve treatment. In addition to physical therapy, two types of prosthetic devices have been proposed to treat individuals with bilateral loss of vestibular inputs: those that provide tactile stimulation to indicate body position in space, and those that deliver electrical stimuli to branches of the vestibular nerve in accordance with head movements. The relative efficacy of these two treatment paradigms, and whether they can be combined to facilitate recovery, is yet to be ascertained.

  1. Spontaneous bilateral fracture of patella.

    Bilateral patellae fractures represent a rare entity, accounting for approximately 2.9% of all lesions interesting in this anatomical district. In most cases found in the published work, they are described as stress fractures or as complications of chronic diseases such as osteoporosis, renal failure and secondary hyperparathyroidism. Although many pathogenetic mechanisms have been supposed, none have been proved for certain. Insufficiency fractures of the patellae are rare events and no data has been published on their incidence. We present a case of bilateral fracture of the patellae due to an indirect trauma occurring in an 85-year-old patient affected by Parkinson's disease, osteoporosis and diffuse degenerative osteoarthritis. X-ray of the knees (anteroposterior and lateral) and magnetic resonance imaging evaluation confirmed the fractures. The patient was treated conservatively. She had a good result, returning to her previous autonomous ambulation. This case is unusual because there was no direct trauma to the knees because of bilaterality, but confirmed previous observations about insufficiency fractures of patellae in the presence of comorbidity. Insufficiency fractures of patellae can be an insidious condition in elderly people. Prepatellar pain, a common symptom in the relapse phase of degenerative arthritis of the knee, should not be underestimated, particularly in patients with diseases influencing metabolism of bone and with an elevated risk of fall. A periodical clinical and instrumental follow up should be done in these patient. Moreover, we underline the necessity of a multidisciplinary approach.

  2. Bilateral Advantages in Subitizing With Visual Masking.

    Pryor, Campbell G; Howe, Piers D L

    2015-01-01

    Performance on a range of visual-processing tasks has been shown to improve when information is split bilaterally across the left and right visual hemifields rather than being restricted to a single visual hemifield. However, a recent study by Delvenne et al. found no such bilateral advantage for subitizing, which is our ability to rapidly and accurately enumerate small quantities of objects. This finding is particularly surprising, as it contradicts the prediction of FINgers of INSTantiation theory that subitizing should benefit from bilateral presentation. Our study investigated the issue by determining if there are any circumstances where a bilateral advantage for subitization occurs. Contrary to Delvenne et al., we found that subitizing could show bilateral advantages, but only when the display was backward-masked. We discuss these findings in relation to how the rate of encoding and the time available for this encoding may affect bilateral advantages in subitizing. A general model is proposed under which bilateral advantages could be explained.

  9. Bilateral cleft lip nasal deformity

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    We report a rare case of bilateral maculopathy that developed with the initiation of sertraline. We conducted a case report and review of the literature. A 23-year-old man rapidly developed maculopathy with associated visual blurring after the initiation of sertraline. Treatment was ceased with the patient subsequently reporting mild improvement in visual symptoms. Maculopathy associated with sertraline use has yet to be established and recognized as an adverse side effect. With only one previous reported case in the literature, this condition requires further awareness. © The Royal Australian and New Zealand College of Psychiatrists 2014.

    Inguinal hernias are rare in females. The authors report a case of bilateral inguinal hernias in a 10-year-old female. On exploration, the patient was found to be having a sliding hernia containing incarcerated ovary as contents on both sides. Peroperatively the contents were reduced, the sac was transfixed at its base and the redundant sac was excised. The repair of this form of hernias is more difficult because of adhesions between the contents and the wall of the sac and risk of damage during dissection. A description of this clinical presentation in the pre operative assessment and operative management are discussed in this report.

    Full Text Available Introduction. In 1814 Giovanni Monteggia first described two cases of fractures of the proximal third of ulna with dislocation of the radial head. These fractures are more common in children than in adults, and mutual Monteggia fracture is a rare complication. This study presents a treatment course of a patient with bilateral Monteggia fracture. Case report. A 55- year-old patient was injured by falling in the yard. Radiography showed bilateral Monteggia fracture type II (by the Badon classification. Operative treatment of fracture was done by a compression plate on the right side and by the zuggurtung technique on the left one. Closed repositioning of the radial head was done on both sides. The patient was wearing a plaster splint for the upper arm for 21 days. After removing the fixation, the function of the elbow was determined by the Broberg Morrey score (BM which was on the right side 45.5 and on the left side 47.5. After the proper physical therapy, four months after the surgery, BM score was 100 on the right side, and 93 on the left one. Conclusion. Surgical treatment and early rehabilitation is the key for the return of good function of both elbows.

    Full Text Available Bilateral ovarian tumour in a girl presents the dilemma of conservative versus aggressive approach towards these tumours. When faced with suspicious tumour and complete replacement of the ovaries bilaterally, bilateral oophorectomy is a viable option, though the certain possibility of infertility and lifelong hormonal supplementation is unavoidable. We report a case of bilateral ovarian masses in a young girl, which on histopathological examination showed mature teratoma with aggregates of proliferating capillary and cavernous sized vessels in the tumour wall. Such associations are rare and must be differentiated from a vascular neoplasm.

Nosso objetivo foi avaliar o estado oxidante/antioxidante de crianças com bronquiolite aguda por meio de mensuração da capacidade antioxidante total do plasma, estado oxidante total e índice de estresse oxidativo. MÉTODOS: As crianças com bronquiolite aguda encaminhadas para o Departamento de Emergência Pediátrica do hospital universitário entre janeiro e abril 2012 foram comparadas a controles saudáveis de mesma idade. Os pacientes com bronquiolite aguda tiveram essa doença classificada como leve e moderada. O estado oxidante e antioxidante foi avaliado pela mensuração da capacidade antioxidante total do plasma, estado oxidante total e índice de estresse oxidativo. RESULTADOS: Foram incluídas 31 crianças com bronquiolite aguda com idade de três meses a dois anos e 37 crianças saudáveis. O estado oxidante total (EOT foi maior em pacientes com bronquiolite aguda do que no grupo de controle (5,16±1,99 µmol H2O2 em comparação a 3,78±1,78 µmol H2O2 [p = 0,004].

    Iatrogenic Cushing syndrome induced by oral and parenteral corticosteroid administration is a well-known complication, and necessary precautions have to be taken. Cushing syndrome, however, following treatment with glucocorticoid-containing eye drops is a very rare complication. To the best of our knowledge, there have been only four reported cases in the literature. Herein, we present an infant boy who developed Cushing syndrome after receiving dexamethasone-containing eye drops after bilateral cataract extraction to prevent postoperative inflammatory complications. At the age of 5 months, after approx. 3 months of dexamethasone therapy, the patient presented with cushingoid facies, nephrocalcinosis and failure to grow. Iatrogenic Cushing syndrome was diagnosed and dexamethasone-containing eye drops were reduced and eventually stopped. Follow-up examinations revealed catch-up growth. Ocularly administered corticosteroids may have substantial systemic side effects in infants.

  1. Bilateral supernumerary primary maxillary canines

    Full Text Available Supernumerary teeth are more common in the permanent than in primary dentition. In the primary dentition, the anomaly is most frequently observed in the maxillary lateral incisor region, followed by the maxillary midline where they are termed as mesiodens. Supernumerary teeth in the primary canine region are rare. This paper describes a rare case of nonsyndromic supernumerary primary maxillary canine distributed bilaterally in a 4-year-old boy. Both the supernumeraries resembled size and shape of normal primary canine. The right supplemental canine is high labially placed, whereas the left one is seen normally aligned in the dental arch distal to lateral incisor. One of the most significant sequelae of primary supernumerary teeth is their duplication in the permanent series. Radiographic examination of supernumerary primary canine did not indicate any such anomaly in the permanent dentition. The patient was kept under observation.

    There has recently been an expansion in the use of bilateral salpingectomy at the time of sterilization to theoretically decrease ovarian cancer risk. We sought to determine if postpartum salpingectomy is equivalent to postpartum bilateral tubal ligation (BTL) in terms of duration, estimated blood loss (EBL), and complication rate. A retrospective case series (Canadian Task Force Classification II-2). An academic inner-city hospital. All patients admitted for delivery of full-term intrauterine pregnancy desiring permanent sterilization between March 2014 and March 2015 were included. Excluded patients included those who had sterilization at the time of the cesarean section or other surgical procedure. Two cohorts were identified, those who had a planned postpartum tubal ligation and those having a postpartum salpingectomy. Postpartum sterilization. Researchers of this study recorded demographics, medical histories, and abdominal surgical histories for all patients who met the inclusion criteria. Surgical times, EBL, and complication rates were reviewed. Unpaired t test calculations were used to identify differences between age, body mass index, parity, and surgical time between the 2 cohorts. Chi-square tests were used to determine the statistical significance between complication rates, history of abdominal surgery, and past medical history of tubal disease between the 2 cohorts. Eighty women were identified, 64 in the BTL group and 16 in the salpingectomy cohort. The demographics of each cohort were equivocal. The average surgical time was 59.13 and 71.44 minutes in the BTL and salpingectomy cohorts, respectively. Of the 80 patients, only 1 had an EBL greater than 50 mL; this patient was in the BTL group. Four complications were noted in the BTL cohort, but none were evident in the salpingectomy group. There were no documented sterilization failures in the follow-up period (median = 9 months). Postpartum salpingectomy is slightly longer in duration but with

    We report a case of bilateral complete failure of adduction following bilateral translid antralethmoidal orbital decompression. We believe the probable mechanism is neuropraxia (temporary dysfunction) of the third cranial nerves' supply to the medial recti, owing to these nerves' occupying an anatomically abnormal position. Partial recovery of adduction occurred over the ensuing six months. Images PMID:2337551

    Full Text Available A dor aguda no joelho de pacientes idosos é freqüente, sendo caracterizada por seu aparecimento súbito, sem causa aparente, com exame radiográfico dentro dos padrões da normalidade, na maioria dos casos. A etiologia da dor aguda no joelho é decorrente de insuficiência das estruturas, e seu quadro clínico difere completamente daquele determinado pela osteoartrose, sendo sempre unilateral e ocorre na grande maioria em pacientes do sexo feminino, após a quinta década de vida, e na região medial do joelho (local de maior carga. Com o propósito de analisar as possíveis etiologias para a dor aguda do joelho de pacientes acima de 60 anos de idade, suas características e tratamento, os autores discutem as etiologias relacionadas à dor aguda: lesão meniscal, fratura por fadiga e osteonecrose idiopática.Acute knee pain in elderly patients is not uncommon, and is characterized by a sudden onset, no apparent cause, and by normal radiographic findings in most cases. The etiology of acute knee pain is the result of insufficient structures, and clinical symptoms are totally different from the symptoms seen in osteoarthrosis. This acute pain in the knee is always unilateral and in the medial region of the knee joint (site with the heaviest load, predominantly in females after the fifth decade of live. In order to consider the possible etiologies for acute knee joint pain in patients older than 60 years, its characteristics and treatment, the authors discuss etiologies related to acute pain: lesion of the meniscus, stress fracture, and idiopathic osteonecrosis.

    Full Text Available A pancreatite aguda é uma patologia grave e com considerável morbidade e mortalidade. Vários fatores são apontados como possíveis causas de pancreatite aguda. Neste relato, será apresentado um caso de pancreatite aguda com possível associação causal com um inibidor seletivo de recaptura de serotonina: sertralina. Após um mês de tratamento com sertralina, uma paciente do sexo feminino, 55 anos, desenvolveu forte dor abdominal e elevação da amilase sérica. Após internação e retirada da sertralina, seus sintomas remitiram e os níveis de amilase voltaram ao normal. Pela potencial gravidade do quadro e pelo amplo uso desta medicação, tal associação deve ser lembrada em investigações de casos de pancreatite aguda.Acute pancreatitis is a severe disease with considerable morbidity and mortality. Many risk factors are causally related to acute pancreatitis. In this report, a case of acute pancreatitis with possible causal relationship with the use of a selective serotonin reuptake inhibitor, sertraline, will be discussed. After one month of treatment with sertraline, a female patient, 55 years-old, developed a severe abdominal pain and showed a serum amylase elevation. She was admitted to the hospital and the use of sertraline was interrupted. After that, the symptoms remitted and the serum amylase level returned to normal. Because of the potential severity of this disease and the widespread use of sertraline, this association should be reminded when investigating possible causes for acute pancreatitis.

  9. Shadow removal using bilateral filtering.

    Yang, Qingxiong; Tan, Kar-Han; Ahuja, Narendra

    2012-10-01

    In this paper, we propose a simple but effective shadow removal method using a single input image. We first derive a 2-D intrinsic image from a single RGB camera image based solely on colors, particularly chromaticity. We next present a method to recover a 3-D intrinsic image based on bilateral filtering and the 2-D intrinsic image. The luminance contrast in regions with similar surface reflectance due to geometry and illumination variances is effectively reduced in the derived 3-D intrinsic image, while the contrast in regions with different surface reflectance is preserved. However, the intrinsic image contains incorrect luminance values. To obtain the correct luminance, we decompose the input RGB image and the intrinsic image. Each image is decomposed into a base layer and a detail layer. We obtain a shadow-free image by combining the base layer from the input RGB image and the detail layer from the intrinsic image such that the details of the intrinsic image are transferred to the input RGB image from which the correct luminance values can be obtained. Unlike previous methods, the presented technique is fully automatic and does not require shadow detection.

  10. Bilateral pneumothorax after orthognatic surgery

    Full Text Available Among complications in orthognathic surgery, the insurgence of pneumothorax is very rare. Pneumothorax is the presence of air or gas in the pleural cavity and it is rare complications in the postoperative oral and maxillofacial surgery patient. The clinical results are dependent on the degree of collapse of the lung on the affected side. Pneumothorax can impair oxygenation and/or ventilation. If the pneumothorax is significant, it can cause a shift of the mediastinum and compromise haemodynamic stability. While 10% of pneumothoraces are asymptomatic, patients often complain of acute chest pain and difficulty breathing. There is a reduction in vital capacity, tachycardia, tachypnoea and a decrease in partial pressure of oxygen with an inability to maintain oxygen saturations. We observed this unusual surgical consequence in a 28-year-old female with negative clinical history and instrumental evaluation after Le Fort I osteotomy and bilateral sagittal split osteotomy (BSSO. No further consequences, no neurological sequelae, no infections and no other osteotomies sequelae were seen. Sudden post-surgical dispnea associated to sub-cutaneous emphysema of the neck and of the thorax must be adequately observed with the aim of monitoring further severe sequelae. The anaesthetic management of the emergency difficult airway in any post-surgical orthognatic treatment can be extremely difficult requiring a multi-disciplinary approach.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. © 2016 The authors.

El objetivo es presentar dos casos clínicos de pancreatitis aguda grave que sufrieron infarto esplénico como complicación de la enfermedad pancreática. Pacientes, participantes: en un periodo de tres meses, dos pacientes fueron diagnosticados de infarto esplénico secundario a pancreatitis aguda. En ambos casos el diagnóstico y seguimiento evolutivo del infarto esplénico se hizo a través de tomografía axial computerizada. Resultados: en el primer paciente, las imágenes muestran de forma inequívoca la afectación de la arteria esplénica por el proceso inflamatorio pancreático. En el segundo, no se pudo demostrar afectación de los vasos esplénicos, por lo que la única posible explicación etiológica es un incremento de coagulabilidad intravascular. Conclusiones: sería recomendable añadir las complicaciones esplénicas al conjunto de complicaciones graves extrapancreáticas de la pancreatitis aguda. La tomografía axial computerizada es de gran utilidad para la detección y seguimiento de las complicaciones esplénicas de la pancreatitis aguda.Background and objective: the close anatomic relationship of the pancreas with the splenic vessels and the spleen is responsible for splenic complications in the course of acute pancreatitis.

Objetivo: caracterizar a los pacientes intervenidos quirúrgicamente en el Hospital Universitario "Comandante Manuel Fajardo" entre 1995 y 2012 a causa de colecciones pericárdicas. Métodos: se realizó un estudio descriptivo transversal con los pacientes atendidos quirúrgicamente en dicha institución por colecciones del pericardio. Constituyeron el universo 24 pacientes: 22 con colecciones agudas y 2 con colecciones crónicas. Resultados: la causa más frecuente de los derrames agudos fue la pericarditis aguda idiopática (25 %. Las colecciones crónicas fueron por pericarditis fibrosa de causa idiopática en el 100 % de los enfermos. La intervención realizada fue la resección del pericardio y el drenaje de las colecciones agudas mediante toracotomía izquierda o por vía preperitoneal subxifoidea. En las colecciones de origen maligno se realizó la resección pericárdica con fines paliativos y, en los derrames por lesión traumática del corazón, la sutura de este órgano fue el tratamiento quirúrgico empleado en todos los casos. En las pericarditis constrictivas, la pericardiectomía radical fue el tratamiento empleado en el 100 % de los casos. Conclusiones: el tratamiento quirúrgico en las colecciones agudas y crónicas del pericardio permite drenar el contenido por una ventana pericárdica obtenida por toracoscopia o por vía preperitoneal subxifoidea, mientras que la toracotomía izquierda es útil en las emergencias. En los derrames crónicos con fibrosis y síntomas de insuficiencia cardíaca, la pericardiectomía radical mediante esternotomía media ofrece los mejores resultados.

    Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

In all groups, amylase serum levels, histologic damage, vascular permeability and pancreatic water content were assessed. Acute pancreatitis was induced by administration of two cerulein injections (20 mcg/kg. A single dose of Evans' blue dye was administered along with the second dose of cerulein. All animals also received a subcutaneous injection of saline solution. After this process, animals undergone hyperthermia were heated in a cage with two 100 W lamps. Body temperature was increased to 39.5ºC and maintained at that level for 45 minutes. Normothermia rats were kept at room temperature in a second cage RESULTS: Control animals had typical edema, serum amylase activity and morphologic changes of this acute pancreatitis model. Hyperthermia post-treatment ameliorated the pancreatic edema, whereas the histologic damage and the serum amylase level remained unchanged CONCLUSIONS: The findings suggest a beneficial effect of the thermal stress on inflammatory edema in experimental acute pancreatitis.RACIONAL: Estudos recentes indicam que a hipertermia pode modificar mecanismos inflamatórios e proteger animais experimentais dos efeitos deletérios da pancreatite aguda induzida por secretagogos OBJETIVO: Avaliar a eficácia da hipertermia como tratamento da pancreatite aguda induzida por ceruleína em ratos MÉTODOS: Vinte animais foram divididos em dois grupos: grupo I (n = 10, ratos com pancreatite aguda induzida por

    Total hip arthroplasty (THA) is an effective and durable treatment option for hip osteoarthritis (OA). As life expectancy continues to increase, so too will the demand for joint arthroplasty in the 10th decade of life, frequently in cases involving osteoarthritis of both hips. Simultaneous bilateral total hip arthroplasty (SBTHA) is a valuable therapeutic option in appropriately selected patients with bilateral degenerative hip disease, although its use in the very elderly is poorly reported on in the literature. A case of bilateral hip OA successfully treated with SBTHA in a nonagenarian is presented and the literature is reviewed.

    Neurofibromatosis is a neuroectodermal systemic disease. A rare variant of this condition is bilateral segmental neurofibromatosis. A 29-year-old man presented with bilateral papillomatous plaques in the lumbar dermatomes. Clinically, the lesions were very similar to an epidermal nevus but histologic examination revealed superficial neurofibromas. Family history, ophthalmologic and neurologic investigations were unremarkable. The unusual morphologic presentation of bilateral segmental neurofibromas in this case points to the wide clinical spectrum of the disease and the significance of histologic examination in systematic nevoid lesions.

  1. The guided bilateral filter: when the joint/cross bilateral filter becomes robust.

    2015-04-01

    The bilateral filter and its variants, such as the joint/cross bilateral filter, are well-known edge-preserving image smoothing tools used in many applications. The reason of this success is its simple definition and the possibility of many adaptations. The bilateral filter is known to be related to robust estimation. This link is lost by the ad hoc introduction of the guide image in the joint/cross bilateral filter. We here propose a new way to derive the joint/cross bilateral filter as a particular case of a more generic filter, which we name the guided bilateral filter. This new filter is iterative, generic, inherits the robustness properties of the robust bilateral filter, and uses a guide image. The link with robust estimation allows us to relate the filter parameters with the statistics of input images. A scheme based on graduated nonconvexity is proposed, which allows converging to an interesting local minimum even when the cost function is nonconvex. With this scheme, the guided bilateral filter can handle non-Gaussian noise on the image to be filtered. A complementary scheme is also proposed to handle non-Gaussian noise on the guide image even if both are strongly correlated. This allows the guided bilateral filter to handle situations with more noise than the joint/cross bilateral filter can work with and leads to high peak signal-to-noise ratio values as shown experimentally.

    Full Text Available As principais causas de inflamação pancreática no mundo são a litíase biliar e o alcoolismo crônico. Admite-se que 10 a 30% das pancreatites agudas sejam idiopáticas. Sugere-se que parte destas são causadas por microlitíase ou barro biliar, identificados pela presença de microcristais no sedimento biliar. Neste estudo, realizou-se análise microscópica da bile obtida por colangiopancreatografia endoscópica, em pacientes com pancreatite aguda idiopática, pancreatite aguda biliar e pancreatite crônica alcoólica - 20 em cada grupo. Pacientes com pancreatite aguda idiopática e microcristais na bile foram submetidos a colecistectomia. Naqueles inaptos à cirurgia efetuou-se esfincterotomia endoscópica ou tratamento com ácido ursodesoxicólico. Pacientes com pancreatite aguda idiopática sem cristais não receberam tratamento específico. A prevalência de microcristais biliares em pacientes com pancreatite aguda idiopática (75% e pancreatite aguda biliar (90% foi significativamente maior que naqueles com pancreatite crônica alcoólica (15%. A detecção de microcristais apresentou sensibilidade de 90%, especificidade de 85%, valor preditivo positivo de 85,7%, valor preditivo negativo de 89,4% e acurácia de 87,5% em identificar pancreatite de origem biliar. Nos pacientes com pancreatite aguda idiopática recurrente, cursando com microcristais, houve redução significante dos episódios de pancreatite após tratamento específico.

    Full Text Available We present a case study of a person (63 year-old man, who has been using statins for 18 years, with rhabdomyolysis of the bilateral adductor muscles associated with strenuous and prolonged eccentric exercises (hiking in a hot environment. Clinical examination showed predominantly on the right side muscle swelling and palpational pain of the bilateral adductor muscle groups and bilateral tibial edema. His serum creatine kinase (CK level was 12218 IU/L. T2-weighted magnetic resonance (MR images showed a high signal intensity in the bilateral adductor muscles of the hip. The patient did not develop complications and returned to his previous performance level in 30 days following adequate hydration and resting of the affected muscles. Strenuous eccentric exercise should be avoided during the course of statin use and clinicians should be aware of present observations when considering the significance of acute CK elevations in patients on statin treatment

    Full Text Available The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we introduce a way to control the tonal weighting coefficients, the flowing bilateral filter, reducing "halo" artifacts typically produced by the regular bilateral filter around a large peak surrounded by two valleys of lower values. In this paper we propose to investigate exact and approximated versions of CPU and parallel GPU (Graphical Processing Unit based implementations of the regular and flowing bilateral filter using the NVidia CUDA API. Fast implementations of these filters are important for the processing of large 3D volumes up to several GB acquired by x-ray or electron tomography.

    Full Text Available Spontaneous bilateral ectopic gestation is very rare. The authors report a case diagnosed and taken care of at Yalgado Ouedraogo Teaching Hospital, Ouagadougou. It was a 30-year-old patient with no known pathological history. She had presented at the obstetric emergencies with a state of hypovolemic shock by haemoperitoneum with digestive disorders, pelvic pain, vaginal bleeding, and a mention of delayed menstruation. The ultrasound coupled with the urinary immunological pregnancy test confirmed the diagnosis of ruptured ectopic pregnancy and a bilateral form was suspected. A laparotomy in emergency confirmed the diagnosis of bilateral ectopic gestation with a right ampullary unruptured pregnancy and a left isthmic ruptured gestation. A bilateral salpingectomy was performed and counseling was made for the use of medical help of procreation in case of future need of pregnancy.

  7. THE EUROPEAN UNION’S BILATERAL APPROACH

    Directory of Open Access Journals (Sweden)

    Ludmila BORTA

    2014-12-01

    Full Text Available The EU is a world economic power and a major trading partner for most countries. All the time, this region has been interested and has acted towards a free and fair trade. The decrease and even the elimination of tariff and non-tariff barriers in the world trade are among the main objectives of the EU strategy for international trade. At the moment, the elusive outcome of the WTO Doha Round has led to the proliferation of bilateral trade agreements worldwide. Although the EU remains committed to further development of the multilateral trading system, however, the EU still has appealed also to the development of bilateral trade relations. The aim of this paper is to illustrate the current bilateral dimension of the common commercial policy of the EU. In conclusion, to describe this bilateral approach of the EU we are using one word, namely “diversity”.

    Full Text Available Renal oncocytomas are the most common benign solid renal tumor, accounting for 3-7% of renal neoplasms. Oncocytomas are multifocal in 2-12% and bilateral in 4-14% of cases. Multifocal bilateral oncocytomas represent only 1.4% of renal cases. We present an extraordinary case of a patient with multifocal bilateral renal oncocytomas during pregnancy. An electronic literature search revealed fewer than 30 reports of on cases of bilateral multifocal renal oncocytomas, none of them occurring in pregnancy. The management of this patient differed from the recommended guidelines for renal masses suspected to be malignant because elective caesarean section and nephrectomy in the second trimester was refused.

    A 26-year-old female presented with abdominal pain and distension in 2003. Clinical evaluation and imaging were suggestive of bilateral benign renal solid masses. Fine needle aspiration showed tubular cells only. Patient was kept under periodic follow up. She reported 4 years later with increase in pain and size of masses, and underwent bilateral staged nephron sparing surgery. The histopathology was reported as bilateral oncocytoma. Two years after surgery, she developed epidural spinal cord compression and liver metastasis. A decompression laminectomy and biopsy revealed conventional renal cell carcinoma (RCC). To our knowledge this is the first case report of sporadic bilateral synchronous hybrid RCC and oncocytoma in a young woman, with spinal epidural metastasis.

    The purpose of this study was to evaluate the bilateral coordination in children and adolescents with visual impairments aged 7 to 18 years in comparison to their sighted peers. An additional objective was to identify the influence of sex and age on bilateral coordination. Seventy-five individuals with congenital severe visual impairment (40 girls and 35 boys) comprised the visually impaired group. The Sighted group comprised 139 youth without visual impairment. Subtest 4 of the Bruininks-Oseretsky Test of Motor Proficiency was administered to test bilateral coordination. To analyze the effect of the independent variables in the results obtained in the Subtest 4, four linear regression models were applied according to group and sex. The results indicated that severe visual impairment and lack of visual sensation had a negative effect on the development of participants' bilateral coordination, which however did not depend on sex or age. © The Author(s) 2016.

    2016-12-15

    An otherwise healthy 34-year-old man was referred to our ear, nose and throat (ENT) clinic for a bilateral maxillary radiologic opacity. This condition was accidentally discovered with a panoramic radiography performed during a follow-up visit after a bilateral endodontic treatment. The patient did not report any specific sinonasal symptom such as purulent nasal discharge, loss of smell and cough, apart from an unspecific sinus pressure. The CT scans showed a bilateral inflammatory process into the maxillary-ethmoidal sinuses and an iron-like density within the maxillary sinuses, while nasal endoscopy showed purulent discharge in the ostiomeatal complex. The patient underwent functional endoscopic sinus surgery under general anaesthesia and the inflammatory material collected was histologically diagnosed as a rare case of bilateral fungus ball. The patient was dismissed the following day with no complications; there were not any sign of recurrence or symptoms during a 4 month follow-up. 2016 BMJ Publishing Group Ltd.

    Bilateral facial palsy is a rare clinical entity caused by myriad disparate conditions requiring different treatment paradigms. Lyme disease, Guillain-Barré syndrome, and leukemia are several examples. In this article, the authors describe the cause, the initial diagnostic approach, and the management of long-term sequelae of bilateral paralysis that has evolved in the authors' center over the past 13 years. A chart review was performed to identify all patients diagnosed with bilateral paralysis at the authors' center between January of 2002 and January of 2015. Demographics, signs and symptoms, diagnosis, initial medical treatment, interventions for facial reanimation, and outcomes were reviewed. Of the 2471 patients seen at the authors' center, 68 patients (3 percent) with bilateral facial paralysis were identified. Ten patients (15 percent) presented with bilateral facial paralysis caused by Lyme disease, nine (13 percent) with Möbius syndrome, nine (13 percent) with neurofibromatosis type 2, five (7 percent) with bilateral facial palsy caused by brain tumor, four (6 percent) with Melkersson-Rosenthal syndrome, three (4 percent) with bilateral temporal bone fractures, two (3 percent) with Guillain-Barré syndrome, one (2 percent) with central nervous system lymphoma, one (2 percent) with human immunodeficiency virus infection, and 24 (35 percent) with presumed Bell palsy. Treatment included pharmacologic therapy, physical therapy, chemodenervation, and surgical interventions. Bilateral facial palsy is a rare medical condition, and treatment often requires a multidisciplinary approach. The authors outline diagnostic and therapeutic algorithms of a tertiary care center to provide clinicians with a systematic approach to managing these complicated patients.

An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 µm in the right eye and of 710 µm in the left eye, as well as an average paracentral pachymetry of 436 and 270 µm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus.

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

Se revisaron los inmunofenotipos de 364 muestras de pacientes adultos derivadas a nuestro laboratorio en un período de 7 años. El inmunofenotipo se realizó por citometría de flujo con un amplio panel de anticuerpos monoclonales con el que se evaluó la expresión de antígenos de linaje linfoide, mieloide y también antígenos de maduración. De las 364 muestras estudiadas, 60.2% presentaron un fenotipo compatible con leucemia mieloide aguda (LMA, 28.8% con leucemia linfoblástica B (LLA-B, 6.6% con leucemia linfoblástica T (LLA-T y 4.4% con leucemias agudas poco frecuentes. La presencia de fenotipos aberrantes se observó en 89% de los casos, los fenotipos aberrantes identificados fueron: 1 infidelidad de linaje: LMA (54%, LLA-B (40%, LLA-T (29%; 2 ausencia de expresión antigénica: LMA (21%, LLA-B (35%, LLA-T (70%; 3 alteración de la expresión antigénica: LMA (67%, LLA-B (66%, LLA-T (84%; 4 asincronismo madurativo: LMA (26%, LLA-B (37% y 5 fenotipo ectópico: LLA-T 96%. El análisis por citometría de flujo multiparamétrica de las leucemias agudas permitió la identificación de fenotipos aberrantes en la mayoría de nuestros pacientes, que son de utilidad para el monitoreo de la respuesta al tratamiento.

Magnetic resonance imaging showed bilateral absence of the ACL, and medial posterior horn meniscal tears. Bilateral arthroscopic partial meniscectomy and anterior cruciate ligament reconstruction was performed. (orig.)

  13. Bilateral Neck of Femur Fractures in a Bilateral Below-Knee Amputee: A Unique Case

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available According to the National Hip Fracture Database, over 64,000 patients were admitted with a hip fracture across England, Wales, and Northern Ireland in 2013, but very few are bilateral, and there are no current cases in the literature of bilateral neck of femur fractures in a patient with bilateral below-knee amputations. We present a case of a 69-year-old bilateral below-knee amputee male admitted to the emergency department with bilateral hip pain and radiological evidence of bilateral displaced neck of femur fractures. The patient subsequently underwent synchronous bilateral total hip replacements under general anaesthetic and an epidural and then went on to make a full recovery. He was discharged 27 days after arrival in hospital. Outpatient follow-up at 3 months has shown that the patient has returned to a similar level of preinjury function and is still able to carry out his daily activities with walking aids and bilateral leg prostheses.

    In Brazil electricity is traded through three segments: the spot market that balances offer and demand, with prices calculated by a cost-based computational model; the regulated market , where prices are settled in public auctions, and the free market for bilateral contracts. As spot and regulated market prices are public information, a seller is able to calculate his opportunity price to trade a bilateral contract in the free market by using the non-arbitrage principle. Thus, the seller searches the price of a bilateral contract in the free market that balances his/her revenues with the value expected in case it were negotiated in the regulated and the spot market. Besides the expected revenue, the seller may also consider the CVaR to measure the risk of her/his bilateral contract in the free market. So this paper develops a binomial lattice approach to price bilateral contracts in the free market, considering the seller's opportunity of negotiations in both regulated and spot markets, and measuring the contract risk directly.

  15. Bilateral trigeminal neuralgia: a therapeutic dilemma.

    Science.gov (United States)

    Tacconi, L; Miles, J B

    2000-02-01

    In order to illustrate the inherent problems of managing bilateral trigeminal neuralgia a retrospective study of the 16 cases of bilateral trigeminal neuralgia, out of just over 300 cases of trigeminal neuralgia, treated over a 14-year period, has been performed. All the patients, presented with a typical history of trigeminal neuralgia and underwent surgical exploration. Pain relief was initially achieved in all cases; however, only four remained cured, three have become pain free after additional rhizotomy, a further one after peripheral cryotherapy and four with medical treatment. Four patients have had bilateral operations for trigeminal neuralgia, but in two cases the pain was relieved on one side only. Bilateral trigeminal neuralgia presents special problems of management with respect to underlying neuropathology (e.g. multiple sclerosis), the need for the limitation of the use of ablative techniques in order to minimise the disability of bilateral sensory and motor dysfunction, and the relatively poor response to microvascular decompression. These factors emphasize the multifactorial nature of the cause of trigeminal neuralgia. Magnetic resonance tomographic angiography is now available and is important in determining the range of therapeutic options for this group of patients.

    2007-09-01

    To report a case of bilateral upper extremity edema associated with amlodipine use in a child. A previously well and normotensive 6-year-old girl presented with a generalized vasculitis of unknown origin and severe hypertension. Large vessels predominantly affecting the neck, chest, and abdomen were found to be involved, resulting in abnormal arterial circulation and significant blood pressure differences between the upper and lower extremities. Multiple antihypertensive agents were initially required to control blood pressure. She was stabilized and discharged on amlodipine 10 mg each evening, atenolol 50 mg/day, and warfarin. Three days later she was noted to have facial and bilateral upper extremity pitting edema. Laboratory and radiologic assessments for possible etiologies were negative. Discontinuation of amlodipine resulted in resolution of edema. As of June 2007, there had been no cases of bilateral upper extremity edema associated with amlodipine use reported in the English literature. Adverse effects of amlodipine, a widely used antihypertensive, have been well reported. These include flushing, headache, and peripheral edema. Lower limb edema is the most common, while periocular and perioral edema have occurred less frequently. Anasarca edema has been described only once in the English literature. According to the Naranjo probability scale, amlodipine was a probable cause of bilateral upper extremity edema in this child. Bilateral upper extremity edema has been associated with amlodipine use in a child with an abnormal arterial circulation. The edema resolved upon discontinuation of the drug.

    We conducted an evaluation of outcomes for microsurgical vasectomy reversal in which sperm are absent from the vas fluid in order to determine a threshold obstructive interval when vasoepididymostomy (VE) may be indicated. Vasectomy reversal was performed for 32 patients with intravasal azoospermia: 25 received bilateral vasovasostomy (VV), 1 had a bilateral VV, 5 underwent VV/VE, and 1 had bilateral VE. Overall, the patency rate was 50% (14 of 28). Five pregnancies (20%) and 3 live births (12%) occurred in 25 patients with sufficient follow-up. One pregnancy was electively terminated and the other is ongoing, for an ongoing or delivered rate of 16%. The patency rate for VV (either bilateral or unilateral) was 55% (12 of 22). Median obstructive interval was 7 years in patent and 15 years in nonpatent cases, respectively, (P =.0027). Sperm were not observed after VV in any case n which the obstructive interval was greater than 11 years. If VV was limited to obstructive intervals of 11 years or less, then the patency rate was 80% (12 of 15) and the pregnancy rate was 38% (5 of 13). The patency rate for bilateral VV was 67% (8 of 12) if clear fluid was observed on at least one side. We conclude that VE is not required in every case of intravasal azoospermia, but it could improve success rates in this setting. Based on our experience, VE may be indicated for intravasal azoospermia if the obstructive interval is more than 11 years.

    2017-12-27

    A rare case of bilateral ventrolateral pontine infarction in a 70-year-old man who developed progressive dysarthria and bilateral sensory disturbance is reported with literature review. He had been diagnosed with hypertension, dyslipidemia, and impaired glucose tolerance 10 years earlier. Ten days before admission, he was aware of the difficulty in walking and speaking, which gradually worsened. On admission he showed bilateral thermal hypoalgesia of face and lower extremities, dysarthria, dysphagia, and ataxic gait. High resolution three-dimensional MRI revealed bilateral ventrolateral pontine infarction with a large atherosclerotic plaque in the ventral side of the basilar artery, which led to a diagnosis of atherothrombotic brain infarction. The atherosclerotic plaque in the basilar artery was thought to be responsible for simultaneous occlusion of the bilateral short circumflex arteries of the pons.

  19. Chronic Bilateral Tibial Stress Fractures with Valgus Treated with Bilateral Intramedullary Nailing: A Case Report

    Steven K Dailey

    2014-01-01

    Full Text Available Introduction: Stress fractures are overuse injuries most commonly seen in athletes, military recruits, and individuals with endocrine abnormalities. It has been demonstrated that chronic cases of anterior tibial stress fractures refractory to conservative management respond well to intramedullary nailing. To our knowledge, only one report has been published concerning patients with bilateral tibial stress fractures treated with bilateral intramedullary nailing. All patients in the series were high-level athletes. We present the case of a non-athletic patient with chronic bilateral tibial stress fractures and associated deformity successfully treated with bilateral intramedullary nails. Case Report: A 23-year-old Caucasian female full-time student presented with chronic bilateral shin pain for approximately five years. She had failed an extensive regimen of conservative management. She was diagnosed with chronic bilateral tibial stress fractures based on history, physical examination, and radiologic findings. She subsequently underwent sequential intramedullary nailing of her tibiae. Both tibiae were in valgus alignment; however, this did not preclude nail placement. The nails deformed upon insertion into the sclerotic canals to conform to the deformation. Post operatively the tibiae united and patient was relieved of her symptoms. Conclusion: Bilateral intramedullary nailing of chronic bilateral tibial stress fractures should be considered as a treatment option for all patients, not just high-level athletes, who fail a trial of conservative management. Additionally, mild to moderate tibial malalignment does not necessarily preclude tibial nailing as the smaller nails placed in sclerotic canals will likely deform on insertion and conform to the canal. Keywords: Bilateral intramedullary nailing, bilateral tibial stress fractures, valgus

    2015-02-01

    Although bilateral paramedian thalamic infarctions occur more frequently in adults than in children, they are rare entities at any age. The syndrome is thought to result from occlusion of the artery of Percheron, which arises as a common trunk from one of the posterior cerebral arteries to supply both paramedian thalamic regions. We describe two children with acute ischemic infarction involving both paramedian thalami developing after infection. The first patient developed mutism with ataxia after chicken pox infection. The second child developed headache, somnolence, agitation, and speech dysfunction following an upper respiratory tract infection. Bilateral thalamic lesions were documented on magnetic resonance imaging of both children. Bilateral infarctions of the paramedian thalamus may result in severe illness and impairment. Common clinical manifestations include disorientation, confusion, hypersomnolence, deep coma and "coma vigil," or akinetic mutism (awake unresponsiveness), as well as severe memory impairment.

    Suresh, Palanisamy S

    2016-09-01

    Reiter's syndrome is commonly associated with conjunctivitis and rarely with uveitis. Bilateral disciform keratitis at presentation is a very rare manifestation in Reiter's syndrome. A 13-year-old boy developed bilateral disciform keratitis with oligoarthritis following an episode of conjunctivitis. In addition he had suspected bacterial keratitis with hypopyon in the left eye as a possible secondary infection of an epithelial defect that is a feature of Reiter's keratitis. Empirical treatment with intensive topical antibiotics as a therapeutic trial completely resolved the hypopyon and the disciform keratitis settled with topical steroid treatment. The patient achieved a best corrected vision of 20/20 in both the eyes 6 weeks after the treatment. Bilateral disciform keratitis can occur as a complication of Reiter's syndrome. Also the possibility of secondary infection of the epithelial defect needs to be borne in mind.

    Full Text Available A 39-year-old male was admitted to our clinic with symptoms of headache, dizziness, nausea, otalgia, otorrhea, tinnitus, and hearing loss in both ears for 3 weeks. Physical examination revealed edema in the tympanic membrane and external ear canal, and pain by palpation in the mastoid area bilaterally. There was no nystagmus, and the rest of the physical examination was otherwise normal. Temporal bone high resolution computed tomography (CT showed a lesion causing erosion in the mastoid cortex, tegmen tympani, ossicles, and in the bone covering the sigmoid sinus bilaterally. There was also erosion in the superior semicircular canal and petrous bone on the left side. Cortical mastoidectomy was performed under general anesthesia. Histopathologic examination of the tissue revealed Langerhans cell histiocytosis (LCH. In this paper a case with LCH, presenting with bilateral mastoid involvement which has been rarely reported in the literature, is discussed with the existing literature.

    2015-06-01

    Full Text Available Clear cell sarcoma of the kidney (CCSK accounts for 2–5% of all pediatric renal malignancies, and is known for its propensity to metastasize to bone and other sites. We are reporting two cases with bilateral CCSK that were diagnosed at our institution. One patient initially presented with bilateral renal masses, as well as pulmonary, hepatic and bone metastasis; while other present only with bilateral masses with no evident distant metastasis. Both patients received aggressive neo-adjuvant chemotherapy to decrease tumor size. One patient completed his designated treatment and initially showed complete remission (CR; eventually suffering from relapse. The other patient’s tumor progressed during the course of chemotherapy. Both cases manifested brain dissemination at the time of relapse or progression. This emphasizes the importance of staging stratification in CCSK. This also illustrates CCSK’s ability to metastasize to bone and other sites including the brain (a primary relapse site in our cases.

    2007-01-01

    Neurofibromatosis type 1 (NF1) is an autosomal-dominant disorder characterized by café-au-lait spots, neurofibromas, intertriginous freckles, and Lisch nodules in the iris. Segmental neurofibromatosis is fundamentally a mosaic variant of NF1. A 66-year-old man visited us with bilateral segmental neurofibromatosis (SN) on the torso. He had multiple neurofibromas on the back bilaterally and on the right abdomen, and partial unilateral lentiginosis on the left abdomen and left back. The patient had noticed the development of papules and nodules on the right abdomen and bilaterally on the back 6 years previously, and had been diagnosed with early gastric carcinoma 5 years previously. To our knowledge, this is only the third reported case of SN associated with internal malignant tumours.

  5. Bilateral fusion of permanent maxillary incisors

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Dental fusion is a rare developmental anomaly, which is included in the anomalies of tooth morphology or shape. Fusion can occur at the level of enamel or enamel and dentin, which results in the formation of a single tooth with enlarged clinical crown. Fusion is more common in deciduous dentition. Incisors are reported to be fused in primary and permanent dentition, but bilateral fusion is a rare occurrence. The prevalence of bilateral fusion in the permanent dentition is less frequent than unilateral fusion and is reported to be around 0.05%. The authors report a case of a 20-year-old male with bilateral fusion of maxillary central and lateral incisors. Multi-disciplinary treatment approach is essential to get the desired esthetic result. The best way to manage these difficult cases depends on a number of factors including the knowledge and technical skills of the practitioner.

  6. Bilateral tactile agnosia: a case report.

    Nakamura, J; Endo, K; Sumida, T; Hasegawa, T

    1998-06-01

    This study reports a 64-year-old right-handed male who manifested bilateral tactile recognition deficits. They were diagnosed as bilateral tactile agnosia, since the patient showed difficulty in semantic association of objects despite preserved hylognosis and morphognosis. The patient had a bilateral lesion in the subcortical region of the angular gyrus. The case reported by Endo et al. (1992) had a right hand tactile agnosia due to a subcortical lesion in the left angular gyrus. Our findings support Endo's hypothesis that tactile agnosia occurs when the somatosensory association cortex is disconnected from the semantic memory store located in the inferior temporal lobe by a subcortical lesion of the angular gyrus. We suggest that the extent of the lesion in the tactual-semantic pathway is related to the severity of tactile agnosia and the types of the tactile naming errors.

    Valentín Santiago Rodríguez Moya

    Full Text Available Desde las primeras descripciones del síndrome de dificultad respiratoria aguda los pediatras intensivistas reconocieron que posee particularidades que la hacen diferente en la población pediátrica. El objetivo de este trabajo es divulgar la definición específica en el modelo infantil, aunque existen similitudes en la fisiopatología del síndrome de dificultad respiratoria en adultos y niños. Se revisaron los conceptos vigentes sobre el síndrome de dificultad respiratoria aguda desde su descripción, a través de los diferentes consensos (desde el de 1994 hasta el de 2015 y se señalaron las recomendaciones en el tratamiento y seguimiento de esta entidad. Los tópicos que se trataron fueron: concepto; prevalencia y epidemiología; fisiopatología, severidad y enfermedades asociadas; soporte ventilatorio; tratamientos secundarios específicos sobre el pulmón; tratamientos concomitantes; monitoreo general y pulmonar; soporte ventilatorio no invasivo; terapia extracorpórea y el seguimiento a largo plazo. Las recomendaciones propuestas en la última conferencia de consenso para el tratamiento del síndrome de dificultad respiratoria en edades pediátricas permiten optimizar el tratamiento e identificar necesidades futuras de investigación del tema.

    In studies aimed at local treatment of experimental osteoarthritis (OA) it is optimal to have an internal (untreated) OA control. Such an approach excludes interanimal variation, and allows paired statistical evaluation of treatment efficacy. For this purpose, we developed and characterized a bilateral version of the canine Groove model. We hypothesized that the bilateral version of the canine Groove model would show consistent and clear development of features of OA similar to those found in the unilateral version. In six Beagle dogs, grooves were surgically made in the articular cartilage of the femoral condyles of both knee joints. Six additional dogs underwent bilateral sham surgery. The degree of OA was quantified 20 weeks after surgery and was compared in retrospect to 23 animals that undergone the same procedure in a single knee joint with the contralateral knee serving as a non-OA control. Bilateral groove surgery resulted in OA. This was based on the observed ineffective repair response in which an increase in proteoglycan synthesis, a diminished retention of these newly formed proteoglycans, and an enhanced loss of resident proteoglycans resulted in a decreased cartilage proteoglycan content. These biochemical effects were corroborated by clear histological features of OA. All these effects were found in femor as well as in the (surgically untouched) tibia. Interestingly, features of OA were slightly more severe in the bilateral model than in the unilateral variant. The bilateral canine Groove model showed consistent and clear development of features of OA, comparable to the unilateral model. (c) 2008 Orthopaedic Research Society.

    This case report presents a military diver who became dysphoric and lost consciousness during a routine surface-supplied dive. The patient regained consciousness spontaneously, but the physical exam was notable for bilateral ophthalmoplegia. Full eye movement was regained during hyperbaric oxygen (HBO2) therapy, and the patient subsequently made a full recovery. Equipment and dive profile analysis led to the conclusion of hypercapnia and arterial gas embolism as the probable causes of the diver's symptoms. This is a unique case of isolated bilateral ophthalmoplegia presenting in a diving injury.

    2016-02-01

    Among the rare cardiac tumors, myxoma, which is mostly located in the left atrium, is the most common type. Bilateral atrial myxoma is extremely rare, and requires urgent surgery. The authors report the case of a 34-year-old male, who presented with one month of right hemiparesis and aphasia and subsequently diagnosed with bilateral atrial myxoma based on transthoracic echocardiography. An urgent operation for intra-cardiac tumor removal was performed with the biatrial approach. Once a diagnosis of myxoma has been made, an urgent operation for tumor removal is necessary due to the risk of serious complications, including sudden death from normal blood flow obstruction.

    Full Text Available Spontaneous tegmen tympani defects are rare with even rarer bilateral cases. The symptoms are nonspecific; hence, a high index of suspicion is required to prevent serious intracranial complications. We present a case of spontaneous bilateral tegmen tympani defects with associated meningoencephalocoeles in a 54-year-old male who presented with the signs and symptoms of severe meningitis. After careful workup which included a lumbar puncture, CT and MRI scans, both defects were repaired using a middle fossa approach. The patient made an uneventful recovery with complete cessation of otorrhoea and improvement in his hearing.

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

  16. "Ostrich sign" indicates bilateral vertebral artery dissection.

    2012-11-01

    Vertebral artery dissections (VADs) comprise about 2% of ischemic strokes and can be associated with trauma, chiropractic manipulation, motor vehicle collisions, whiplash, amusement park rides, golfing, and other motion-induced injuries to the neck. We present a case of bilateral extracranial VAD as a complication of conducting an orchestra. To our knowledge, this has not been documented in the literature. Conceivably, vigorous neck twisting in an inexperienced, amateur conductor may place excessive rotational forces upon mobile portions of the verterbral arteries, tear the intima, deposit subintimal blood that extends longitudinally, and cause neck pain and/or posterior fossa ischemic symptoms. Magnetic resonance angiography examinations of axially oriented slices of bilateral VADs resemble the face of an ostrich. This observation is similar to the "puppy sign," in which bilateral internal carotid artery dissections resemble the face of a dog. Craniocervical dissections of either the carotid or vertebral arteries have the potential to form an aneurysm, cause artery-to-artery embolism, or completely occlude the parent artery, resulting in an ischemic stroke. Because bilateral VADs in axial magnetic resonance angiographic sections stand out like the eyes of an ostrich, and because the fast identification of VADs is so critical, we eponymize this image the "ostrich sign."

    Full Text Available The article deals with the author’s interpretation of the process of teaching profession specific bilateral translation to student teacher of English in the Master’s program. The goal of the model of teaching profession specific bilateral translation development is to determine the logical sequence of educational activities of the teacher as the organizer of the educational process and students as its members. English and Ukrainian texts on methods of foreign languages and cultures teaching are defined as the object of study. Learning activities aimed at the development of student teachers of English profession specific competence in bilateral translation and Translation Proficiency Language Portfolio for Student Teachers of English are suggested as teaching tools. The realization of the model of teaching profession specific bilateral translation to student teachers of English in the Master’s program is suggested within the module topics of the academic discipline «Practice of English as the first foreign language»: Globalization; Localization; Education; Work; The role of new communication technologies in personal and professional development. We believe that the amount of time needed for efficient functioning of the model is 48 academic hours, which was determined by calculating the total number of academic hours allotted for the academic discipline «Practice of English as the first foreign language» in Ukrainian universities. Peculiarities of the model realization as well as learning goals and content of class activities and home self-study work of students are outlined.

Departamento de Medicina e Cirurgia Veterinária, Instituto de Veterinária, Universidade Federal Rural do Rio de Janeiro, BR 465 Km 7, Seropédica RJ 23890-000, Brasil. E-mail: saulocaldas@hotmail.com A case of bilateral queilosquise in a cattle two years old was reported. Clinically, there was cachexia, difficulty in grasping food and water intake. The clinical examination revealed that the nasal orifices were discontinuous with the upper lip, which allowed communication between the nostrils and mouth in its rostral portion, crowding of incisors (tweezers, as well as exposure of medium and the 2nd corner and of the tongue. In this case, the bilateral queilosquise was the result of flaws in fusion of the maxillary process and the medial nasal process and its surroundings, probably due to mineral deficiencies of pregnant cow. This pathogenesis was suggested by excluding other possible causes, the knowledge of the existence of mineral deficiencies in the region where the event occurred and bad nutritional status of pregnant female.

Significant findings: The initial radiograph of the pelvis revealed bilateral hip dislocations. Small bony fragments were noted in the right hip joint, suggestive of an underlying fracture. The sacroiliac joints and the pelvic ring were intact. In the emergency department, bilateral hip reductions were performed using the Captain Morgan technique.1 The post-reduction film showed reduction of the bilateral hip dislocations with extensive comminuted and displaced fractures of the right and left acetabula. Discussion: Bilateral hip dislocations are extremely rare, occurring in only 1% of all hip dislocations,2 and require immense force, typically occurring in MVCs (74%.3-7 Associated injuries include fracture of the acetabulum or femoral head, sciatic nerve damage, and obstruction of the blood supply to the femoral head.8 X-ray imaging and CT scans are used to assess the injury and to detect intra-articular fragments.3 Definitive treatment is achieved by closed reduction if possible; otherwise open reduction is utilized.9 Post-reduction therapy includes a non-weight-bearing period of time. Complications include avascular necrosis of the femoral head, osteonecrosis, and posttraumatic arthritis, the occurrence of which can be decreased by early reduction.4,10-12 This patient underwent bilateral

    Full Text Available OBJETIVO: Analisar pacientes com menos de dois anos de idade com leucemia linfoblástica aguda atendidos no período de 1990 a 2010, em um centro de referência estadual. MÉTODOS: Estudo clínico, epidemiológico, transversal, descritivo e observacional. Pacientes incluídos tinham menos de dois anos de idade, com leucemia linfoblástica aguda, tratados no período de 1990 a 2010 na unidade de oncologia pediátrica de um centro de referência estadual, totalizando 41 casos. RESULTADOS: Todos os pacientes eram Caucasianos e 60,9% eram do sexo feminino. Com relação à idade, 24,38% tinham menos de seis meses, 17,07% tinham entre seis meses e um ano e 58,53% mais do que um ano de idade. A idade de seis meses foi estatisticamente significante para o desfecho de óbito. Os sinais e sintomas predominantes foram febre, hematomas e petéquias. Uma contagem de leucócitos superior a 100.000 foi observada em 34,14% dos casos; hemoglobina inferior a 11 em 95,13% e contagem de plaquetas inferior a 100.000, em 75,61% dos casos. Infiltração do sistema nervoso central estava presente em 12,91% dos pacientes. Em relação à linhagem, a linhagem B predominou (73%, mas a linhagem de células T foi estatisticamente significativa para o óbito. Trinta e nove por cento dos pacientes tiveram recorrência da doença. Em relação ao estado vital, 70,73% dos pacientes morreram, sendo choque séptico a principal causa. CONCLUSÕES: leucemia linfoblástica aguda em crianças tem uma alta taxa de mortalidade, principalmente em crianças menores de um ano e linhagem derivada de células T.

    Full Text Available OBJETIVO: Descrever os principais aspectos epidemiológicos, clínicos, diagnósticos e do tratamento de crianças com pancreatite aguda. FONTES DOS DADOS: Realizada revisão sistemática das bases de dados MEDLINE e SciELO nos últimos 5 anos sobre pancreatite aguda em crianças, bem como consultadas referências relevantes dos textos obtidos. SÍNTESE DOS DADOS: Os casos de pancreatite aguda em crianças recebem crescente atenção nos últimos anos, sendo verificado um aumento na incidência da doença em diversos estudos. As principais etiologias em crianças envolvem doença biliar, pancreatite secundária a medicamentos, pancreatite hereditária recorrente e trauma, sendo até 30% dos casos sem etiologia definida. O diagnóstico baseia-se na combinação de aspectos clínicos, laboratoriais com elevação das enzimas acinares e testes radiológicos. Tratamento de suporte inicial, com reposição volêmica adequada e correção dos distúrbios metabólicos, além de terapêutica nutricional específica, são os pontos fundamentais no manejo dos quadros agudos. Complicações a longo prazo são incomuns, e as taxas de mortalidade, inferiores às da população adulta. CONCLUSÃO: O diagnóstico precoce e o manejo apropriado podem contribuir para a melhor evolução da criança com pancreatite e prevenir as complicações imediatas e tardias relacionadas à doença. Mais estudos são necessários para melhor elucidar aspectos relacionados ao diagnóstico clínico e radiológico da pancreatite em crianças, bem como aspectos da terapêutica nutricional nessa faixa etária.

    Full Text Available Introducción: la obstrucción biliar es motivo frecuente de morbilidad en los pacientes con metástasis hepáticas, adenopatías periportales y cáncer hepatobiliopancreático. La colangitis aguda es la complicación más temida, debido a su mortalidad. En este trabajo se presentan los primeros abordajes percutáneos realizados por cirujanos del Hospital Clínicoquirúrgico "Hermanos Ameijeiras" como herramienta para el tratamiento urgente de esta entidad. Objetivo: caracterizar el drenaje percutáneo transparietohepático de urgencia en pacientes con colangitis aguda e ictericia obstructiva. Métodos: se realizó un estudio descriptivo, prospectivo y aplicado con 30 pacientes atendidos de esta forma en dicha institución entre enero de 2008 y diciembre de 2010. Resultados: el diagnóstico etiológico preponderante fue el de tumor maligno de la cabeza del páncreas. La localización baja de la lesión duplicó a la localización alta. La mejoría clínica de la ictericia se evidenció en la mayoría de los pacientes después de una semana tras el procedimiento: el drenaje percutáneo constituyó el método definitivo en el 73,3 % de los pacientes. Las edades medias para los distintos diagnósticos etiológicos exhibieron diferencias estadísticamente significativas. No hubo complicaciones ni mortalidad relacionadas con el procedimiento. Conclusiones: el drenaje biliar percutáneo guiado por ultrasonido es una herramienta útil y segura para el tratamiento de urgencia de la colangitis aguda. Es un método que pueden realizar los cirujanos generales con entrenamiento adecuado y específico, y tiene asociadas pocas complicaciones.

    Full Text Available A lesão pulmonar aguda e sua forma mais grave, a síndrome da angústia respiratória aguda, são o denominador comum de várias doenças que podem provocar uma inflamação exagerada nos pulmões. Nos últimos anos, essa variabilidade tem sido atribuída, pelo menos em parte, a fatores genéticos. O presente estudo tem por objetivos revisar o papel dos principais genes envolvidos na suscetibilidade, morbidade e mortalidade na lesão pulmonar aguda e na síndrome da angústia respiratória aguda. Através de pesquisa nas bases de dados PubMed e LiLACS, empregando-se os unitermos lesão pulmonar aguda, síndrome da angústia respiratória aguda e síndrome da angústia respiratória do adulto em combinação com polimorfismos genéticos, foram selecionados 69 artigos, dos quais 38 foram incluídos nesta revisão. Foram também considerados artigos relevantes extraídos das referências bibliográficas nos artigos selecionados das bases de dados. Os polimorfismos genéticos são variantes gênicas presentes em pelo menos 1% da população. A presença destas variantes genéticas pode influenciar a expressão de mediadores da resposta inflamatória, afetando diretamente a suscetibilidade à lesão pulmonar aguda, a intensidade da inflamação no parênquima pulmonar, a evolução e o desfecho destes pacientes. Estudos de associação com grandes populações e passíveis de reprodução permitirão de modo definitivo a inclusão da genômica no arsenal diagnóstico, prognóstico e terapêutico de pacientes com lesão pulmonar aguda/síndrome da angústia respiratória agudaAcute lung injury and its most severe presentation, acute respiratory distress syndrome, are a common denominator for several diseases which can lead to exaggerated lung inflammation. In the last years this variability has been ascribed, at least partially, to genetic issues. This study aims to review the role of the main genes involved in acute lung injury and acute respiratory

    We present the first ever reported case of bilateral total knee replacements in a congenital amputee with bilateral fibular deficiency. A 60 year old woman with bilateral fibular hemimelia presented with advanced osteoarthritis in both her knees for which bilateral total knee replacements was performed. The left knee replacement was followed up at 12 months and the right knee at 7 years. Oxford knee scores improved from 14 to 40 for the left knee and were 37 for the right knee. She was able to walk independently to a distance beyond 400 m. Modification in the surgical procedure and postoperative rehabilitation is discussed. Mid-term follow-up of 7 years reaffirms total knee replacement as a viable option for below knee amputees with knee osteoarthritis. Copyright © 2010 Elsevier B.V. All rights reserved.

    2015-01-01

    Full Text Available Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis.

DISEÑO: estudio retrospectivo descriptivo. MUESTRA: 20 pacientes con diagnóstico de retinoblastoma bilateral que consultaron al Hospital Universitario San Vicente de Paúl, de Medellín, Colombia, entre 1997 y 2007. MÉTODO: se hizo enucleación del ojo con el tumor de mayor tamaño. En el otro ojo se hizo tratamiento con TTT, con el láser diodo (810 nm, spot amplio, solo o combinado con otras terapias. RESULTADOS: se dividió a los pacientes en dos grupos: 16 pacientes (32 ojos en el grupo 1 tratados conservadoramente y 4 pacientes (8 ojos en el grupo 2 con tratamiento convencional. El rango de edad fue de 1-72 meses en el grupo 1 y de 1-12 meses en el grupo 2. El tiempo de seguimiento fue de 7-67 meses para el grupo 1 y de 13-73 meses para el grupo 2. En el grupo 1 se hizo enucleación de 16 ojos (50%, radioterapia externa de uno (3,1%, quimioterapia más termoterapia de 5 (15,6% y quimioterapia más termoterapia más crioterapia de 10 (31,3%. En todos los pacientes se logró preservar al menos un ojo. En el grupo 2, se enuclearon 7 ojos (87,5% y se hizo radioterapia externa más enucleación en un paciente (12.5%.

    Full Text Available Como consecuencia de la infección por el virus de la inmunodeficiencia humana tipo-1 (HIV-1, otros patógenos como citomegalovirus (CMV y herpes simple tipo 1-2 (HSV 1-2 pueden comprometer tanto el sistema nervioso central como el periférico. Estos agentes pueden involucrar también a la médula espinal y causar una mielitis aguda necrotizante. Esta complicación ocurre por lo general en pacientes con enfermedad HIV/sida avanzada y marcada inmunodeficiencia, con recuentos de linfocitos T CD4+ de menos de 50 cél/µL. El cuadro clínico, los cambios en el LCR y las neuroimágenes generan una importante sospecha diagnóstica. Es fundamental el inicio precoz de la terapia antiviral específica. Se presenta un paciente con enfermedad avanzada debida al HIV-1 y mielitis aguda necrotizante por CMV y HSV bajo la forma clínica de síndrome de la cola de caballo.In the setting of HIV infection, cytomegalovirus (CMV and herpes simplex virus type 1-2 (HSV 1-2 can affect both the central and peripheral nervous systems. These agents can involve the spinal cord and produce a necrotizing transverse myelitis. This usually occurs in AIDS patients with severe immunodeficiency: CD4 + lymphocyte counts typically are less than 50 cell/µL. The clinical presentation, CSF and imaging studies can provide a high level of suspicion diagnosis. Prompt initiation of antiviral specific drugs is essential.

  6. Nutritional support in patients with severe acute pancreatitis Soporte nutricional en pacientes con pancreatitis aguda grave

    Directory of Open Access Journals (Sweden)

    2007-04-01

    Full Text Available Severe acute pancreatitis is associated with a systemic inflammatory response leading to a hypermetabolic, hypercatabolic condition; for those reasons, patients suffering from this disease require an excellent artificial nutritional support in order to maintain the structural integrity and the function of vital organs with minimal pancreatic secretion. Total parenteral nutrition has been the standard practice in the treatment of patients with severe acute pancreatitis because of the favorable outcomes of early nutritional support while avoiding pancreatic stimulation; however, recent evidence suggests there are potentially greater benefits with enteral as compared with parenteral nutrition, including fewer septic and metabolic complications and lesser costs. That is why present guidelines for the management of acute pancreatitis recommend that enteral instead of parenteral nutrition be used in patients with severe acute pancreatitis. La pancreatitis aguda, especialmente en su forma grave, está asociada con una respuesta inflamatoria sistémica que lleva a un estado de hipermetabolismo e hipercatabolismo, en el que se requiere un excelente soporte nutricional que permita mantener la integridad estructural y la función de los órganos vitales con un estímulo mínimo de la secreción pancreática. La nutrición parenteral total era el soporte de elección, que permitía obtener todos los beneficios de la nutrición temprana sin estimular la secreción pancreática; pero la evidencia actual muestra mayores beneficios con la nutrición enteral, porque se asocia con menos complicaciones infecciosas y metabólicas y con disminución en los costos. Por ello las guías actuales de tratamiento de la pancreatitis aguda grave recomiendan como primera elección el soporte nutricional enteral.

    Full Text Available Objetivos: apresentar uma revisão acerca de questões controversas, relativas ao manejo farmacológico utilizado nos pacientes pediátricos portadores de asma aguda. Fontes dos dados: foram utilizadas informações de artigos publicados em revistas científicas nacionais e internacionais, selecionadas das bases de dados Lilacs e Medline. Síntese dos dados: o artigo foi estruturado em tópicos, apresentando aspectos consensuais no tratamento farmacológico da asma infantil. Questões relacionadas à utilização de inaladores dosimetrados versus nebulizadores, o papel das drogas ß2-adrenérgicas utilizadas pela via endovenosa, bem como das metilxantinas e do sulfato de magnésio, são abordados de maneira crítica. Conclusões: os ß2-agonistas administrados pela via inalatória, associados aos coricosteróides, permanecem o tratamento de eleição para episódios agudos de asma na população pediátrica. Tanto os nebulizadores quanto os inaladores dosimetrados, acoplados a espaçadores, são efetivos para alívio dos sintomas agudos. Pacientes refratários ao tratamento convencional, que evoluem para quadros de asma aguda grave, devem ter considerada a utilização de drogas ß2-agonistas pela via endovenosa, desde que adequadamente monitorizados. Quanto às metilxantinas e ao sulfato de magnésio, devem ser considerados alternativas secundárias para pacientes selecionados.

    Spontaneous bilateral coxofemoral luxations and their clinical managements are described in four dogs. Luxations in each case occurred while the patient was in a controlled environment with no possibility of trauma. While all cases had bilateral luxations, the luxations occurred in a staged fashion in two of the four cases. Treatment varied with each case, but included closed reduction, triple pelvic osteotomy, prosthetic capsulorrhaphy, toggle pin, ischioilial pinning, total hip replacement, and femoral head and neck ostectomy. Other than femoral head and neck ostectomy, results were uniformly poor, with reluxation being the most common complication. Evidence of pre-existing degenerative changes was minimal, particularly considering the ages of the patients (range, three to 12 yrs). Histopathological evaluation of joint capsules, round ligaments, and femoral heads are warranted in future cases.

    Inferior shoulder dislocation (luxactio erecta) is a rare lesion affecting approximately 0.5% of dislocations of this joint. The vast majority of these cases occur unilaterally. In September 2004, a 43 year old man was brought to the emergency room of the University Hospital of Santa Maria (HUSM) complaining of bilateral shoulder pain and inability to lower the arms, as a result of a fall with the arms abducted, while carrying out work activities. After physical examination and radiological exams, it was found that the patient had a bilateral inferior shoulder dislocation. He was referred to the surgical ward and after intravenous sedation, both shoulders were reduced by closed reduction using the traction-countertraction maneuver. The patient was discharged the day after the reduction. Both arms were immobilized with a velpeau sling in total adduction and intrarotation, with instructions to maintain immobilization for three weeks. The patient was also advised to receive physiotherapy.

    Two experiments examined the effect of illusion of control on in-group favoritism found in the minimal group situation (Tajfel, Billig, Bundy, & Flament, 1971). In bilateral dependency condition, each member made allocation decisions for in-group as well as out-group participants. It was exactly the same situation used in the original studies under the minimal group paradigm, and the subjects knew that their reward allocation too depended on others' decisions. In contrast, in unilateral dependency condition, the subjects made allocation decisions knowing that theirs were not dependent on others' decisions. In Experiment 1, an in-group bias in reward distribution was found in the bilateral dependency condition, but not in the unilateral condition. In Experiment 2, it was found that only those who felt illusion of control exhibited such an in-group bias. Results of the experiments therefore confirmed that illusion of control explained in-group favoritism, as Karp, Jin, Yamagishi, and Shinotsuka (1993) originally hypothesized.

    2003-07-01

    Incontinentia Pigmenti is an X-linked dominant neurocutaneous disorder with central nervous system manifestations in 30% of cases, including seizures and mental retardation. Ischemic or hemorrhagic cerebrovascular accidents have been reported rarely in incontinentia pigmenti. Chart review and literature search was performed following identification of the index case. We describe a patient with incontinentia pigmenti who developed bilateral cerebrovascular accidents in the neonatal period, with resultant severe neurologic sequelae. This is the second reported case of bilateral cerebrovascular accidents in a patient with incontinentia pigmenti. This finding may be secondary to cerebrovascular anomalies, similar to those observed in the retina. Recognition of cerebrovascular accidents as a complication of incontinentia pigmenti will hopefully lead to earlier recognition and treatment.

    Although traumatic injury of the facial nerve is a relatively common condition in neurosurgical practice, bilateral lesions related to fracture of temporal bones are seldom seen. We report the case of a 38-year-old patient admitted to Intensive Care Unit after severe head trauma requiring ventilatory support (Glasgow Coma Scale of 7 on admission). A computed tomography (CT) scan confirmed a longitudinal fracture of the right temporal bone and a transversal fracture of the left. After successful weaning from respirator, bilateral facial paralysis was observed. The possible aetiologies for facial diplegia differ from those of unilateral injury. Due to the lack of facial asymmetry, it can be easily missed in critically ill patients, and both the high resolution CT scan and electromyographic studies can be helpful for correct diagnosis.

    Unilateral and bilateral sternoclavicular joint (SCJ) dislocations are rare injuries. The difficulty in assessing this condition often leads to delay in diagnosis and treatment. We report a rare case of bilateral asymmetrical traumatic SCJ dislocations in a 45-year-old male. The right anterior SCJ dislocation was reduced in the emergency room (ER) and resulted in residual instability. The left posterior SCJ dislocation was asymptomatic and unnoticed for six months. It is important for ER physicians and orthopaedic surgeons to be able identify and treat this condition. All suspected SCJ dislocations should be evaluated by computed tomography (CT) scan for confirmation of the diagnosis and evaluation of both SCJs. Posterior SCJ dislocation is a potentially fatal injury and should not be overlooked due to the presence of other injuries. Surgical intervention is often necessary in acute and old cases.

    Taurodontism is a morphologic change characterized by wide pulp chambers, displaced toward the apical floor of the tooth and short roots. To describe the characteristics of multiple bilateral taurodontism in a female patient. A 13-year-old female patient evaluated for ectopic eruption of the lower right canine. Physical examination revealed no alteration or apparent mental retardation. Intraoral exam detected multiple carious lesions. Periapical and panoramic X-rays revealed short roots and wide and elongated pulp chambers in the second upper and lower molars. Taurodontism was determined in 2, 15, 18, and 31. Findings emphasize the importance of radiographic assessment for diagnosing taurodontism, which might present unusual characteristics, such as multiple and bilateral appearance. The absence of a syndrome should not be used to rule out the possible manifestation of this morphologic variation. Copyright © 2010 American Association of Endodontists. Published by Elsevier Inc.

    Full Text Available Xanthogranulomas (XGRs of the choroid plexus are rare, asymptomatic, and benign lesions usually found incidentally. Here, we present a case of a 47-year-old male with bilateral XGR of the choroid plexus with periventricular edema and discuss our case in relation to a review of existing literature pertaining to the radiology of XGRs. To the best of our knowledge, this is the first reported case of bilateral trigonal XGR causing brain edema without ventricular dilatation. Despite the fact that they can cause hydrocephalus, XGRs are silent and benign lesions. Although the etiopathology of XGRs remains poorly understood, enhanced imaging analyses may provide additional information regarding edema and focal white matter signal changes.

    2011-01-01

    Full Text Available Bacterial meningitis is a relatively common infection of the cerebrospinal fluid (CSF and leptomeninges. The clinical picture evolves rapidly and, if treatment is delayed, can result in a variety of long-term sequelae, including death. Acute kidney injury in the setting of bacterial meningitis usually results from hypotension and volume depletion and resolves with appropriate treatment. Meningococcaemia with profound hypotension, and/or disseminated intravascular coagulopathy (DIC may very rarely lead to bilateral renal cortical necrosis. In this context, renal recovery is extremely unlikely. We present two cases of meningococcaemia complicated by bilateral renal cortical necrosis and, ultimately, end stage kidney disease. We also present a review of the literature on the subject. The cases outline the importance of early aggressive intervention by a multidisciplinary team.

    Full Text Available 【Abstract】There is a dearth of case reports de-scribing simultaneous bilateral patellar tendon ruptures in the medical literature. These ruptures are often associated with systemic disorders such as lupus erythematosus or chronic steroid use. The author describes a case of a 24-year-old man who sustained traumatic bilateral patellar ten-don ruptures without any history of systemic disease or steroidal medication. We repaired and reattached the rup-tured tendons to the patella and augmented our procedure with allogeneic tendon followed by wire loop reinforcement. One year after operation, the patient regained a satisfactory range of motion of both knees with good quadriceps strength and no extensor lag. The recurrent microtrauma from a history of intense sports activity and a high body mass index may have played an important role in this trauma event.

    This case study describes a 37-year-old male who suffered a bilateral transverse acetabulum fracture with a fracture of the posterior wall and a double-sided dorsal hip dislocation in combination with a left-sided femoral head fracture (Pipkin IV) while skiing in a "fun park". The accurate diagnosis and presurgical planning was made by means of a computed tomography (CT) scan and a subsequent 3D reconstruction. After a primarily executed shielded repositioning of the bilateral hip dislocationearly secondary and anatomical reconstruction of the double-sided acetabulum fracture was possible using the Kocher-Langenbeck approach. A consistent physiotherapy as well as rehabilitation finally led to a positive clinical result for the patient.

    Full Text Available INTRODUÇÃO: Diversos estudos evidenciam que as alterações fisiopatológicas, quando associadas ao estresse, podem influenciar a fisiologia renal e estão associadas ao aparecimento de doenças. Entretanto, não foi encontrado nenhum estudo que tivesse realizado investigação associando estresse e lesão renal aguda. OBJETIVO: Avaliar a associação entre os eventos vitais estressores e o diagnóstico de lesão renal aguda, especificando as classes de eventos mais estressores para esses pacientes, nos últimos 12 meses. MÉTODOS: Estudo caso-controle. Foi realizado no Hospital São Paulo da Universidade Federal de São Paulo e no Hospital dos Servidores do Estado de São Paulo. Foram incluídos pacientes com lesão renal aguda, sem doenças crônicas, assistidos em Centros de Terapia Intensiva ou semi-intensivas. Os Controles incluíram pacientes assistidos nos mesmos Centros de Terapia Intensiva, com outras doenças agudas, exceto lesão renal aguda e, também, sem doenças crônicas. Dos 579 pacientes inicialmente identificados, 475 responderam ao instrumento Social Readjustment Rating Scale (SRRS e 398 pacientes foram pareados por idade e sexo (199 casos/199 controles. RESULTADOS: Constatou-se que a frequência dos eventos vitais estressores nos casos apresentava equivalência estatística aos controles. A regressão logística para examinar os efeitos combinados das variáveis independentes associados aos eventos estressantes evidenciou que: o aumento da idade e as classes econômicas AB intensificam a chance da presença do evento estressante em cerca de duas vezes; as classes socioeconômicas AB do Hospital São Paulo elevam a chance de evento estressante. CONCLUSÕES: O presente estudo não evidenciou que o grupo com lesão renal aguda estivesse associado à maior frequência de eventos estressores, mas idade e renda elevadas e, ainda, o tipo de centro clínico estão associados.

    Full Text Available Aspergillus endophthalmitis is a devastating inflammatory condition of the intraocular cavities that may result in irreparable loss of vision and rapid destruction of the eye. Almost all cases in the literature have shown an identified source causing aspergillus endophthalmitis as a result of direct extension of disease. We present a rare case of bilateral aspergillus endophthalmitis. A 72-year-old woman with a history of diabetes mellitus, congenital Hirschsprung disease, and recent culture-positive candida pyelonephritis with hydronephrosis status post-surgical stent placement presented with difficulty opening her eyes. She complained of decreased vision (20/200 with pain and redness in both eyes – right worse then left. Examination demonstrated multiple white fungal balls in both retinas consistent with bilateral fungal endophthalmitis. Bilateral vitreous taps for cultures and staining were performed. Patient was given intravitreal injections of amphotericin B, vancomycin, ceftazidime, and started on oral fluconazole. Patient was scheduled for vitrectomy to decrease organism burden and to remove loculated areas of infection that would not respond to systemic antifungal agents. Four weeks after initial presentation, the fungal cultures revealed mold growth consistent with aspergillus. Patient was subsequently started on voriconazole and fluconazole was discontinued due to poor efficacy against aspergillus. Further workup was conducted to evaluate for the source of infection and seeding. Transthoracic cardiogram was unremarkable for any vegetation or valvular abnormalities. MRI of the orbits and sinuses did not reveal any mass lesions or bony destruction. CT of the chest was unremarkable for infection. Aspergillus endophthalmitis may occur because of one of these several mechanisms: hematogenous dissemination, direct inoculation by trauma, and contamination during surgery. Our patient's cause of bilateral endophthalmitis was through an

    We describe a rare case of bilateral tubal pregnancy following natural conception in a woman with no other known risk factor than two former caesarean sections. Intraabdominal adhesions following the caesarean sections complicated the salpingectomy thus diminishing certainty of a healthy contralateral tube. The woman was readmitted three weeks later and had an additional salpingectomy on behalf of an unrecognized tubal pregnancy. Considering the rising caesarean section rates clinicians need to be certain of no additional ectopic pregnancy while performing the primary operation.

    Patellar fractures are uncommon injuries and account for approximately 1% of all fractures. In this article, a 35-year-old male patient who sustained a collision deceleration accident with bilateral comminuted transverse patellar fractures is presented. For this patient, open reduction and internal fixation with tension band technique, using two Kirschner wires and cerclage wire was applied for both fractures. At the first postoperative day, isometric quadriceps and active range of motion exercises were begun and the patient was allowed to walk full weight bearing with two crutches while both extremities were immobilized in a hinged brace allowing maximum 30 degrees of flexion. At postoperative fourth week brace immobilization was terminated. However, the patient was advised to use crutches for two weeks more to prevent any complications that may arise during walking because of the bilaterally of the injury. At six weeks solid union was achieved. During the last visit at postoperative second year, the patient had no complaints and the range of motion was full. In this paper a case of bilateral patella fractures is presented as a consequence of a dashboard injury, and the pathomechanical and therapeutical aspects of such an injury is discussed.

    To report an exceptional case of bilateral synovial chondromatosis (SC) of the temporomandibular joint (TMJ) and discuss diagnostic approaches, treatment options and follow-up data. A 38-year-old woman presented with left preauricular swelling. Initial imaging studies revealed TMJ effusion only. Six years later, synovial calcifications were detected in the left TMJ; the right TMJ space was widened and presented incipient calcium deposits. Open arthrotomy of the left TMJ was performed, with removal of multiple cartilaginous loose bodies and complete synovectomy. Periodic controls proved the asynchronic development of intra-articular bodies in the right TMJ. SC is a metaplastic arthropathy that is uncommon in the TMJ. Bilaterality is exceptional. Diagnosis is often delayed due to the non-specific symptoms, progressive developmental stages and clinicians' lack of awareness of the condition. Magnetic resonance imaging (MRI) is particularly helpful in defining disease extension, excluding a possible tumour and detecting internal derangement. Definitive diagnosis requires arthroscopic or open examination and histopathological analysis. Recurrences are infrequent after arthrotomy, removal of loose bodies and complete synovectomy. SC is an uncommon condition in the TMJ. Bilateral involvement is extremely rare. MRI is effective for diagnosis and postoperative follow-up. Complete synovectomy usually yields an excellent prognosis. Copyright © 2010 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.

  19. Multilateral, regional and bilateral energy trade governance

    2014-12-01

    The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

  20. High Performance, Three-Dimensional Bilateral Filtering

    Energy Technology Data Exchange (ETDEWEB)

    Bethel, E. Wes

    2008-06-05

    Image smoothing is a fundamental operation in computer vision and image processing. This work has two main thrusts: (1) implementation of a bilateral filter suitable for use in smoothing, or denoising, 3D volumetric data; (2) implementation of the 3D bilateral filter in three different parallelization models, along with parallel performance studies on two modern HPC architectures. Our bilateral filter formulation is based upon the work of Tomasi [11], but extended to 3D for use on volumetric data. Our three parallel implementations use POSIX threads, the Message Passing Interface (MPI), and Unified Parallel C (UPC), a Partitioned Global Address Space (PGAS) language. Our parallel performance studies, which were conducted on a Cray XT4 supercomputer and aquad-socket, quad-core Opteron workstation, show our algorithm to have near-perfect scalability up to 120 processors. Parallel algorithms, such as the one we present here, will have an increasingly important role for use in production visual analysis systems as the underlying computational platforms transition from single- to multi-core architectures in the future.

  1. Rigorously defined hemicrania continua presenting bilaterally.

    Science.gov (United States)

    Southerland, Andrew M; Login, Ivan S

    2011-10-01

    Hemicrania continua (HC) is a headache syndrome characterized by continuous, unilateral head pain, autonomic features, and a complete therapeutic response to indomethacin. Although HC is classified as a unique entity among primary headache disorders, it clearly shares features with other primary headaches, including trigeminal autonomic cephalalgias, and chronic daily headaches, such as chronic migraine and chronic tension-type headache. In addition, the diagnosis is often delayed secondary to a relatively low incidence and the occurrence of some phenotypic variability as found in previous case series. A 62-year-old woman presented with 5 months of unremitting, bilateral headache with significant autonomic symptoms during exacerbations of pain. Neurological examination and imaging studies were normal. After failure to respond to numerous previous therapeutic medicines and interventions, she experienced complete resolution following administration of indomethacin and eventual remission on sustained treatment. This case demonstrates that hemicrania continua with requisite autonomic features can occur in a purely bilateral form. Although the definitive aspects of HC continue to evolve, a bilateral headache meeting the current criteria warrants a therapeutic trial of indomethacin.

    We report a case of bilateral adrenal incidentaloma caused by the capsulatum variety of Histoplasma capsulatum diagnosed in a 74 years old man born in and a life time resident of Treviso, Italy, with the exception of two years spent in Pakistan (1964-1966) as a well-driller. The patient was hospitalized in 1995 for alcoholic chronic hepatitis, chronic Helicobacter pylori gastritis and post-infarction ischemic cardiomyopathy. Abdominal ultrasound incidentally showed bilateral adrenal masses (the right one 6.3 cm in diameter) confirmed by computed tomography, with adrenal function within normal limits. After three months, the patient was again hospitalized due to evening fever, asthenia, anorexia, weight loss and occasional hyperhidrosis. Abdominal ultrasound showed an increase of the right adrenal lesion with normal adrenal function. Ultrasound-guided fine needle aspiration did not prove useful for diagnosis. Accordingly, a laparotomy with bilateral biopsy was performed; histology showed the presence of numerous tissue form cells of H. capsulatum variety capsulatum. Serum anti-H. capsulatum antibodies were negative. Since March, 1996, the patient was given itraconazole and his symptoms quickly regressed but the computed tomography findings, however, have not changed and the patient has adrenal hypofunction that is being treated with cortisone acetate.

    The spread of infection from the ethmoid sinuses to the orbit occurs directly through a congenital dehiscence of the lamina papyracea or via haematogenous spread through ophthalmic venous system. Hence orbital complications of paediatric rhinosinusitis are usually unilateral at presentation. We describe three children with bilateral orbital cellulitis that occurred as a complication of rhinosinusitis without intracranial spread of the infection. The children ranged in the age group from 4 to 7 years. All these children had a prolonged hospital stay from 14 to 25 days and underwent multiple surgical procedures to drain the subperiosteal abscess. These children presented to the hospital with bilateral orbital cellulitis without significant past history. All of them on radiological evaluation showed subperiosteal abscess involving only one orbit. They were taken up for functional endoscopic sinus surgery and the subperiosteal abscess was drained endoscopically with partial removal of lamina papyracea. One case required second surgery despite good recovery for two days post first surgery. Two cases had severe unilateral visual loss at presentation but both recovered dramatically after the surgery. All cases had uneventful recovery with no residual disability. The purpose of this article is to discuss the reasons for bilateral orbital complications of rhinosinusitis at initial presentation despite the previous hypothesis of unilateral involvement.

    Burkitt lymphoma, is described as an aggressive form of non-Hodgkin lymphoma of B cells which occurs most often in children and young adults, ovarian lymphoma can appear as a primary lesion or more commonly referred to as a metastasis. Primary ovarian lesions are rare manifestations corresponding to 0.5% of non-Hodgkin lymphoma and 1.5% of ovarian tumors. Clinic case: 31 years old female with general weakness, march incapacity, dyspnea, hyporexia, fever, diaphoresis, weight loss of 20 kg, flat abs with abdominal pain; Ca125 610 U/ml. Abdominal computed tomography shows a solid aspect tumor which affects the right pelvic cavity. Bilateral ovarian tumors were removed. Microscopically, both lesions show a "starry sky" pattern composed by a monotonous infiltration of lymphocytes mixed with large and clear macrophages, several atypical mitoses, and necrosis and hemorrhage areas. Immunohistochemistry was positive for CD10, CD20, and negative for CD3 and high Ki67 proliferation index. Bilateral ovarian Burkitt's lymphoma was diagnosed. Bilateral ovarian Burkitt's lymphoma is a rare entity, with a variability of presentations, the abdominal pain and abdominal tumors are the most frequent. The patient's prognosis at short term is poor, therefore it's necessary to know this entity and make an early diagnosis.

    Full Text Available This article focuses on issues related to the identification and investigation of the lymph node metastases with bilateral breast cancer. The presence of metastases in the lymph nodes determines the stage of the disease, and introducing a form of tumor progression, characterizes the course and prognosis for the future in a specific patient. Thus, the identification of possible morphological and immunohistochemical characteristics of the tumor tissue and their comparison with the frequency and severity of regional lymph nodes would help to solve the problem of the identification of prognostic factors and markers associated with the risk of nodal metastasis in bilateral breast cancer. This work is relevant due to the fact that the literature on this issue to date are treated ambiguously, and answers to many questions, unfortunately, no.The authors performed a morphological study of the tumor tissue from 600 patients suffering from unilateral and bilateral breast cancer. To avoid false results were studied only cases corresponding to the histological type of invasive carcinoma of non-specific type. The study found that a greater number and a greater percentage of the affected lymph node metastases were observed in patients with bilaterally synchronous tumors. The patients of this group of metastatic lymph nodes was detected more frequently in the presence of infiltrative component of three or more types of structures with the presence of these discrete groups of tumor cells, and the observed maximum degree of inflammatory infiltration of the tumor stroma. In the group of patients with unilateral breast cancer nodal metastasis often detects when triple negative molecular genetic type of the lesion, with large amounts of tumor site, in the presence of infiltrative component of three or more types of structures with the obligatory presence of these microalveolar structures and discretely spaced groups of tumor cells and the highest severity of

    A 57-year-old woman experienced bilateral acute ischemic optic neuropathy after spine surgery. Routine MR imaging sequence, T2-weighted image, showed subtle high signal intensity on bilateral optic nerves. A contrast-enhanced T1 weighted image showed enhancement along the bilateral optic nerve sheath. Moreover, diffusion-weighted image (DWI) and an apparent diffusion coefficient map showed markedly restricted diffusion on bilateral optic nerves. Although MR findings of T2-weighted and contrast enhanced T1-weighted images may be nonspecific, the DWI finding of cytotoxic edema of bilateral optic nerves will be helpful for the diagnosis of acute ischemic optic neuropathy after spine surgery.

    The bilateral brachial plexus block is considered a contraindication, due to the possible development of complications, such as: toxicity from local anaesthetics or bilateral diaphragmatic paralysis. However, with the real time visualisation provided by the ultrasound scan, these complications have decreased and it is a safer procedure. Four cases are presented where the bilateral block was performed using guided ultrasound, as the patients were unable to receive general anaesthesia due to a history of adverse effects or the use of opioids in the post-operative or by the prediction of a difficult airway associated with obesity. A systematic review of the literature from January 1993 to June 2013, was also performed by using a search in the MEDLINE, EMBASE, ARTEMISA, LILACS, Google data bases, in Spanish and English language with the following words: bilateral brachial plexus block, bilateral interscalene block, bilateral infraclavicular block, bilateral supraclavicular block, bilateral lateral supraclavicular block, bilateral axillary block, ultrasound-guided bilateral brachial plexus block. Based on the evidence found, ultrasound-guided bilateral brachial plexus block in selected patients and expert hands, is no longer a contraindication.

    In cases of bilateral clefts of lip and palate there is often a vertical and transversal deficit of the cleft segments. Ideally these problems can be solved orthodontically. In severe cases there is a need of surgical support. Distraction osteogenesis allows the correction of transversal, horizontal, and vertical deficits. A case of a 13-year-old girl with a bilateral cleft of lip and palate is presented. The patient had a severe deficit of the distal cleft segments concerning the vertical and transversal dimension. Osteotomy of the segments was performed and a vertical distraction followed by a transpalatal distraction procedure was used to correct the discrepancies.

    Currently there is no consensus regarding the use of bilateral simultaneous percutaneous surgery for Hallux valgus treatment. Although the technique described in M. Prado's book, recommends operating only one foot at a time there are no published studies confirming it. The aim of this study was to evaluate whether there is a difference between the results of patients that have been percutaneously operated on one foot and those operated on both feet at the same surgical time for mild to moderate Hallux valgus correction. We did a retrospective single centre evaluation of 93 feet (61 patients) with Hallux valgus operated percutaneously. 29 patients were operated unilaterally (group I) and 32 bilaterally simultaneously (group II) between 2005 and 2009. The Metatarsophalangeal angle (MPA), Intermetatarsal angle (IMA) and Distal metatarsal articular angle (DMAA) were evaluated pre- and postoperatively. The AOFAS score, the degree of patients' satisfaction and the complications were evaluated postoperatively. The mean follow-up was 24.0 months in group I, and 28.0 in group II. The average postoperative AOFAS score was 86.8, 82.9 in group I and 88.6 in group II (p>0.05). 90.6% were satisfied or very satisfied in group I, and 89.7% in group II (p>0.05). There was no statistically significant difference (p>0.05) in the average correction of MPA, DMAA, and IMA. The complications rate was similar in both groups. The similar results obtained in both groups suggest that the simultaneous bilateral percutaneous surgery gives equivalent results to the unilateral, which has an important socioeconomic impact since there is only one recovery time for both feet.

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

Os lactentes cujos cuidadores relataram dificuldades de alimentação durante a internação tiveram um número maior de alterações de deglutição na avaliação. A concordância intraexaminador foi considerada muito boa. Conclusões: Lactentes com bronquiolite viral aguda apresentaram alterações de deglutição, acrescidas de mudanças na frequência respiratória e nas medidas das taxas de saturação de oxigênio. Sugere-se, assim, risco para a disfagia.

    Full Text Available Se realizó un estudio longitudinal y prospectivo a 126 pacientes que ingresaron al Servicio de Diarreas Agudas del Hospital General Docente "Armando Enrique Cardoso", en el período comprendido entre junio de 1998 y enero de 1999. A 71 pacientes se les ofrecieron microelementos (vitamina A, sulfato de zinc y fumarato ferroso con el objetivo de conocer los beneficios de los microelementos en la enfermedad diarreica aguda. Al concluir el estudio se pudo comprobar que el grupo de pacientes suplementados tuvo una estadía más corta y la duración del episodio fue menor. Además se halló que en estos pacientes el número de deposiciones es menor, así como la afectación nutricional. También se comprobó cómo la recuperación nutricional es mucho más rápida, así como la recuperación del apetito. Se pudo mostrar cómo la consistencia de las deposiciones al tercer día de tratamiento, en el grupo que recibió micronutrientes, mejoró.A longitudinal and prospective study was conducted among 126 patients that were admitted in the Service of Acute Diarrheas of "Armando Enrique Cardoso" General Teaching Hospital between June, 1998, and January, 1999. 71 patients were administered microelements (vitamin A, zinc sulfate and ferrous fumarate in order to know their benefits in the acute diarrheal disease. On concluding the study, it was proved that the length of stay and the episode were shorter in the group of supplemented patients. It was also observed that the number of defecations as well as the nutritional affectation were lower in these patients and that the nutritional recovery and the recuperation of appetite were faster. The consistency of the defecations improved on the third day of treatment in the group that received micronutrients.

    Full Text Available El dolor es probablemente el principal motivo de consulta en las urgencias estomatológicas y es precisamente el dolor de la pulpitis aguda el que comentamos en este trabajo. El dolor pulpar en sí mismo es similar al dolor que resulta por inflamación de los órganos viscerales y, por lo tanto, podrían ser inadecuados los intentos de explicarlos por comparación con los nociceptores de estructuras somáticas. Se propone analizar el comportamiento del dolor como consecuencia de una pulpitis aguda, con un nuevo enfoque, asimilándolo como el dolor proveniente de estructuras viscerales con manifestaciones dolorosas alejadas del sitio o zona dañada y en el propio diente en que el tejido ha sido injuriado y evoluciona rápidamente hacia la necrosis. Establecemos una analogía entre el dolor visceral como el generado de la pulpa y el del tipo somático profundo como el correspondiente a la afectación periapical por rápida evolución de la inflamación hacia la necrosis.Pain is probably the chief complaint in dental emergencies and this paper deals precisely with the pain caused by acute pulpitis. The pulpar pain itself is similar to the one resulting from inflammation of the visceral organs and, therefore, the attempts to explain these pains by comparing them with the nociceptors of somatic structures may be inappropiate. It is our objective to analyze the behaviour of pain caused by acute pulpitis with a new approach, assimilating it as the pain from visceral structures with painful manifestations far from the damaged site or zone and it is the own tooth whose tissue has been affected and evolves rapidly to necrosis.We establish an analogy between the visceral pain as the one generated by the pulpa and that of deep somatic type as the corresponding to the periapical affection by the fast evolution of inflammation to necrosis.

Os animais foram divididos em dois grupos denominados controle e experimento, e estes subdivididos em três subgrupos com períodos de observação de 12, 24 e 48 horas. No grupo experimento foi realizada a oclusão do lume apendicular por meio de sutura seromuscular circular a 8 cm da extremidade distal do apêndice cecal, com fio de polipropileno 4-0. No controle foi feita somente a simulação da cirurgia. Os aspectos macroscópicos (aumento do tamanho, necrose, perfuração, aderência e secreção na cavidade abdominal bem como os microscópicos do grupo experimento, evidenciaram uma progressão das alterações anatomopatológicas mostrando haver uma relação entre a intensidade dos achados histopatológicos e o tempo de observação. Conclui-se que o método utilizado causa apendicite aguda com alterações anatomopatológicas distintas, de acordo com a fase evolutiva da doença.The evolving phases of acute appendicitis were studied experimentally. Sixty female rabbits (Oryctogalus cuniculus of New Zealand lineage weighing about 2510 to 3040 g were divided in two groups: a control group and experimental group. The experimental group was divided into three subgroups for observation after 12, 24 and 48 hours of the operation, that consisted on a 4-0 polypropylene circular suture at 8 cm from the distal part of the cecal appendix. The control group was sham operated. The macroscopic exam (increase of the appendix volume, necrosis, perfuration, adherence and secretion in the abdominal cavity and the microscopic finding showed a progression in the anatomopathological alterations. There was a close relationship between the histopathological findings and time after the appendiceal obstruction. We conclude that the method

    Full Text Available Acute renal failure is a frequent entity in the elderly. This is due on one hand to the structural and physiological changes of the aged kidney, and on the other hand to the exposure of this population to polypharmacy and their reduced capability to metabolize drugs. In the present report we present a case of a seventy year-old woman who developed acute renal failure secondary to severe dehydration with a clinical and laboratory pattern of intermediate syndrome: laboratory results compatible with parenchymal renal insufficiency (elevated urinary sodium, plasma urea and creatinine, but with a positive response to hydration. The main characteristics of the aged kidney that predispose to the development of an intermediate syndrome are: the vascular dysautonomy and reduced capability of sodium and water reabsorption. The intermediate syndrome is a typical pattern of pre-renal insufficiency in the elderly. RESUMEN: La insuficiencia renal aguda es frecuente en el anciano. Esto se debe por un lado a los cambios estructurales y funcionales propios del riñón senil, y por otro a la gran exposición que esta población tiene a la polifarmacia, y su reducida capacidad para metabolizar los medicamentos. En este reporte presentamos el caso de una mujer de 70 años que desarrolló una insuficiencia renal aguda secundaria a severa deshidratación, mostrando un patrón clínico y de laboratorio propio de un sindrome intermedio: laboratorios compatibles con una insuficiencia renal parenquimatosa (sodio urinario, uremia y creatininemia elevadas, pero con una respuesta favorable a la hidratación. Las principales características del riñón senil que predisponen al desarrollo del sindrome intermedio: son la disautonomía vascular y la reducida capacidad en la recuperación de sodio y agua El sindrome intermedio es un patrón típico de insuficiencia prerrenal en el anciano.

    Full Text Available To present a rare complication, such as bilateral cataracts, in a man who sustained a high-voltage electrical injury. A 35- year-old man was admitted with a complaint of decrease in visual acuity. He had a history of a contact with a power line carrying 30.000 volts of electricity while working at a construction site. Examination at a burn center revealed second-degree facial, neck and left foot burns. One month later, the patient underwent amputation of fourth and fifth toes of his left foot. During the next 6 months, he noted decreasing vision in both eyes. Ocular examination 1 year after the accident revealed that the patient’s visual acuity had deteriorated to 1/10 in both eyes. The cornea on the left eye showed superficial punctate opacities. The lenses in both eyes had anterior subcapsular cortical lens opacities and posterior subcapsular opacities. Uncomplicated bilateral phacoemulsification surgery with intraocular lens implantation was performed and the patient’s visual acuity returned to 10/10 in both eyes. We noted that the fundus remained normal in both eyes. Electrical cataracts are still a serious potential complication that may occur after electrical injury. Awareness of this by burn team members is important for providing optimal treatment to those who have suffered an electrical injury. (Turk J Ophthalmol 2011; 41: 197-9

    To alert health professionals on presence and extent of phantom pain and sensation following bilateral upper limb amputation. Of a total of 140 war-related bilateral upper limb amputees in Iran, 103 subjects were thoroughly examined in this cross-sectional study by a physical medicine specialist. The patients were questioned for the presence of phantom pain and sensations, and frequency and intensity of the feeling were recorded. At 17.1 +/- 6.1 years after injury, 82.0% of the 103 amputees suffered from phantom sensation, including varying degrees of phantom limb pain in 53.9% of stumps. Phantom phenomena had a higher frequency in the right extremities, but this was not statistically significant (p > 0.01). Of those amputees who had phantom pain or sensation, 51.2% reported that they 'always' had phantom limb sensation; and approximately one-fourth of the subjects (24.6%) 'always' had phantom pain. Among the stumps who reported phantom pain (N=112), the pain was excruciating (38.5%), distressing (34.9%) or discomforting (25.6%). A significant statistical relation between phantom limb sensation and level of amputation was observed (p phantom pain; medical and surgical modalities only bring temporary relief, and less than 1% of the respondents achieve permanent relief through different treatment methods.

    The paper presents the results of gait parameters as a function of unilateral weight. The object of the research was a woman walking on a stationary surface and carrying in his hand weights from 0 to 15 kg. Her movement was recorded by 6 cameras recording the location of 34 markers placed at appropriate points in the body. 3D reconstruction was performed for each of the reflecting markers. Tested signals were changes in the value the joint angles of ankle, knee and hip. On the basis of about 6 cycles of movement of each load, a model for the average gait cycle was developed. The result of the experiments are graphs of changes the joint angles as a function of time, bilateral cyclograms, synchronized bilateral cyclograms and regression lines. The conclusion of the study is to determine how one-sided load affects gait asymmetry. Simple and easy to interpret method of presentation of results were also shown. Studies were conducted using VICON system.

Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

    To describe the clinical course of bilateral acute idiopathic maculopathy (BAIM), and to analyze its pathophysiology. A 33-year-old Japanese woman presented with a sudden, severe, bilateral visual disturbance following a flu-like illness. She was examined by fluorescein angiography (FA), indocyanine green angiography (IA), scanning laser ophthalmoscopy (SLO), optical coherence tomography (OCT), and multifocal electroretinography (mfERG). A diagnosis of BAIM was made in this patient based on typical ophthalmoscopic features, which included a pathognomonic yellowish-white foveal lesion. FA demonstrated a breakdown of the outer blood-retinal barrier, with the size and location corresponding to the white lesion, and IA disclosed a choroidal circulatory disturbance. SLO demonstrated that the deep retinal and choroidal layers were disorganized, and OCT showed retinal edema. Electrophysiological dysfunction was detected by mfERGs. After steroid therapy, the patient's visual acuity recovered to normal. The pooling of fluorescein dye and the OCT-determined retinal edema were resolved. However, the physiological dysfunction detected by mfERGs remained. We conclude that the major abnormality in BAIM is an alteration of the retinal pigment epithelium causing severe edema.

    To analyze the clinical characteristics and treatment effect between bilateral (bi-) and unilateral (uni-) sudden sensorineural hearing loss (SSNHL). Four hundred and eighty cases of SSNHL were retrospective study, which were divided into two groups of bi-SSNHL (n = 40) and uni-SSNHL (n = 440). Clinical characteristics and treatment effects were compared of the two groups. The incidence rate of bi-SSNHL was 8.3 percent and uni-SSNHL was 91.7 percent of all patients with SSNHL. Bi-SSNHL occurs more commonly in patients of old age, diabetes mellitus, and lipid panes abnormalities compared to uni-SSNHL. Twenty-eight ears in the bi-SSNHL group showed hearing recovery (35%), compared with 56.4 percent of patients with uni-SSNHL. Bi-SSNHL and uni-SSNHL may have a completely different clinical characteristics and treatment effect, that implies a different pathophysiology and prognosis. Recognition their different clinical characteristics and treatment effect between bilateral and unilateral SSNHL can help in counseling and managing the patients and correctly evaluate the prognosis.

    Meniere disease (MD) is a heterogeneous clinical condition characterized by sensorineural hearing loss, episodic vestibular symptoms, and tinnitus associated with several comorbidities, such as migraine or autoimmune disorders (AD). The frequency of bilateral involvement may range from 5 to 50%, and it depends on the duration of the disease. We have performed a two-step cluster analysis in 398 patients with bilateral MD (BMD) to identify the best predictors to define clinical subgroups with a potential different etiology to improve the phenotyping of BMD and to develop new treatments. We have defined five clinical variants in BMD. Group 1 is the most frequently found, includes 46% of patients, and is defined by metachronic hearing loss without migraine and without AD. Group 2 is found in 17% of patients, and it is defined by synchronic hearing loss without migraine or AD. Group 3, with 13% of patients, is characterized by familial MD, while group 4, that includes 12% of patients, is associated by the presence of migraine in all cases. Group 5 is found in 11% of patients and is defined by AD. This approach can be helpful in selecting patients for genetic and clinical research. However, further studies will be required to improve the phenotyping in these clinical variants for a better understanding of the diverse etiological factors contributing to BMD. PMID:27822199

    A 13-months old boy was admitted in National Heart Foundation Hospital and Research Institute on 3 August 2011 with the diagnosis of Dextrocardia, A-V discordance, DORV, large perimembranous VSD, severe infundibular and valvular PS, bilateral SVC. He was operated on 10 August 2011. Bilateral bidirectional Glenn shunt was done off pump along with interruption of PDA. Antegrade pulmonary blood flow was minimized by tight PA banding. Baby was extubated 3 hours after surgery but had to reintubate immediately due to intense respiratory distress. Subsequent three trials of extubation failed. Chest x-ray revealed elevation of both the hemidiaphragm. Ultrasonogram of abdomen and Bronchogram along with fluoroscopy done and bilateral diaphragmatic palsy was diagnosed. Tracheostomy was done on 25th August 2011. Plication of left hemidiaphragm was done on 27th August and right hemidiaphragm plication was done on 10th September 2011. Though it took long period of time we managed to take him out of ventilator on 57th postoperative day. He was oxygen dependent for a period of time and finally he managed to take his own breath without tracheostomy tube from 67th postoperative day. After a long eventful postoperative hospital stay he was discharged home on 78th postoperative day. Discharge Chest x-ray revealed well expanded lung with flattened diaphragm. Echo revealed well functioning bilateral Glenn shunt. Tracheostomy wound healed nicely and there was no evidence of tracheal stenosis.

    Conclusion:. Surgical outcomes of bilateral reconstructions in patients with abdominal scars are generally comparable with ones in patients without prior surgery; however, some problems have been identified. These procedures might have some intraoperative considerations and often require increased operative times. Apart from the traditional preoperative computed tomography angiography, intraoperative imaging (e.g., fluorescence angiography may be advocated in patients with abdominal scars.

    Full Text Available Background. The risk of ovarian cancer is increased in the association of ovarian tumor, ascites, and hydrothorax with the significant elevated tumor marker CA-125. However, this association can be observed in a rare clinical and benign pathological entity, that is Demons-Meigs’ syndrome. Objective. To describe a rare case of Demons-Meigs' syndrome observed in our department. Methods. A black African woman of 35 years old, seventh gravida and fourth parous, underwent a total abdominal hysterectomy with bilateral salpingoophorectomy for large bilateral ovarian masses associated with significant ascites, bilateral pleural effusion, and particular highly elevated tumor marker CA-125 (1835 UI/mL in a pronounced general alteration condition. Results. The postoperative course was uneventful characterized by a complete remission of hydrothorax and ascites with normal level of CA-125 three months after tumor excision. Histology of both masses revealed a bilateral ovarian fibrothecoma, a benign tumor of the ovary, thus confirming the diagnosis of Demons-Meigs’ syndrome. Conclusion. The Demons-Meigs syndrome, although it strongly mimics the clinical picture of malignant metastatic ovarian cancer, remains a disease with benign prognosis after surgical tumor resection. This is a rare condition that must be known and recognized by practitioners to avoid unnecessary practices.

    Full Text Available Purpose The aim of the study was to evaluate the efficacy and safety of bilateral single-session retrograde intrarenal surgery in the treatment of bilateral renal stones. Materials and Methods From December 2008 to February 2012, 42 patients who had undergone bilateral single-session retrograde intrarenal surgery (RIRS and laser lithotripsy were included in the study. The procedures were performed in the lithotomy position on an endoscopy table under general anesthesia, beginning on the side in which the stone size was smaller. Plain abdominal radiography, intravenous urograms (IVU, renal ultrasonography (USG and / or non-contrast tomography (CT scans were conducted for all patients. The success rate was defined as patients who were stone-free or only had residual fragment less than 4 mm. Results A total of 42 patients (28 male, 14 female with a mean age 39.2 ± 14.2 were included in the present study. The mean stone size was 24.09 ± 6.37 mm with a mean operative time of 51.08 ± 15.22 minutes. The stone-free rates (SFR were 92.8% and 97.6% after the first and second procedures, respectively. The average hospital stay was 1.37 ± 0.72 days. In two patients (4.7%, minor complications (Clavien I or II were observed, whereas no major complications (Clavien III-V or blood transfusions were noted in the studied group. Conclusions Bilateral single-session RIRS and laser lithotripsy can be performed safely and effectively with a high success rate and low complication rate in patients with bilateral renal stones.

    In the absence of firm recommendations, we analyzed whether unilateral thoracic puncture is sufficient for bilateral pleural effusion (PE), or if the procedure needs to be performed in both sides. Prospective study of patients seen consecutively for bilateral PE during a period of 3 years and 9 months. All patients underwent simultaneous bilateral thoracocentesis. The standard protocol variables collected in our hospital served as study parameters. Size of PE, presence of chest pain or fever, or accompanying lung abnormalities, different attenuation values on chest computed tomography, presence of loculated pleural fluid, and radiological resolution in a single side were also evaluated. A total of 36 patients (19 men; mean age 68.5 ± 16.5 years) were included. The etiology of the effusion was different in each side in only 2 patients (5.6%). In 6/32 cases (18.8%), the biological analysis of the pleural fluid (in terms of transudate/exudate) from both sides did not correspond with the etiological diagnosis of the effusion. Correlation between biochemical parameters analyzed in the fluid from both sides (Pearson's correlation coefficient) ranged between 0.74 (LDH) and 0.998 (NT-proBNP). As different diagnoses in each side were found in only 2 patients, the circumstances in which bilateral diagnostic thoracocentesis would be necessary could not be determined. Simultaneous bilateral thoracocentesis does not appear to be recommendable. Larger series are needed to establish which factors might suggest the need for simultaneous puncture of both PE.

    Sterilization via bilateral total salpingectomy is slowly replacing partial salpingectomy, as it is believed to decrease the incidence of ovarian cancer. Our objective was to compare short-term intra and post-operative complication rates of bilateral total salpingectomy versus partial salpingectomy performed during the course of a cesarean delivery. A large series of tubal sterilizations during cesarean sections were studied in a single tertiary medical center between 1/2014 and 8/2016 before and after a policy change was made, switching from partial salpingectomy to total salpingectomy. Patients who underwent bilateral partial salpingectomy using the modified Pomeroy technique were compared with those who underwent total salpingectomy. Operative length, estimated blood loss, postpartum fever, wound infection, need for re-laparotomy, hospitalization length, and blood transfusions were compared. During the study period, 149 women met inclusion criteria. Fifty parturients underwent bilateral total salpingectomy and 99 underwent partial salpingectomy in the course of the cesarean section. Demographic, obstetrical, and surgical characteristics were similar in both groups. Mean cesarean section duration was comparable for partial salpingectomy and total salpingectomy (a median of 35 min in both groups, P = 0.92). Complications were rare in both groups with no significant differences in rates of postpartum fever, wound infection, re-laparotomy, hospitalization length, estimated blood loss, transfusions, and readmissions within 1-month postpartum. Rates of short-term complications are similar in patients undergoing bilateral partial salpingectomy and total salpingectomy during cesarean deliveries, making the latter a feasible alternative to the former.

    Full Text Available Un gran número de insecticidas organofosforados se usan en todo el mundo a diario. Las intoxicaciones ocurren generalmente de forma accidental por exposición laboral, o intencional, con fines suicidas. Los organofosforados producen sus efectos tóxicos a través de la inhibición de la acetilcolinesterasa, la enzima responsable de la hidrólisis del neurotransmisor acetilcolina, produciendo ácido acético y colina, productos químicamente inertes. La unión entre los organofosforados y la acetilcolina es una unión irreversible espontáneamente, sin embargo, puede ser reversible con el uso de antídotos específico llamados oximas. La administración temprana de pralidoxima es crucial y muy útil si se inicia en las primeras seis horas luego de la intoxicación aguda. La atropina produce un beneficio clínico dramático para los síntomas muscarínicos del síndrome colinérgico. Pueden ocurrir complicaciones importantes en los pacientes por intoxicación con organofosforados, como hipotensión, arritmias cardíacas fatales, síndrome intermedio, distres respiratorio, neumonía y aún disfunción cerebral severa.

    Full Text Available Insuficiencia renal aguda (IRA es el término con el cual se designa a la reducción abrupta y sostenida del filtrado glomerular, de la cual resulta la retención de productos de desecho del metabolismo corporal. Clásicamente se dividen los mecanismos de la IRA en pre-renal, parenquimatoso, y obstructivo.En el caso de la IRA parenquimatosa, ésta pareciera ser el resultado de la sumatoria de las múltiples variables: necrosis y apoptosis tubular, alteración de la barrera de filtración, retrodifusión del filtrado glomerular, vasoconstricción intra-renal, contracción del mesangio, obstrucción intratubular, inflamación intersticial, activación de enzimas proteolíticas, entre otros.Por este motivo se postula que sólo una mirada de perspectiva multicausal de este síndrome pareciera ser la estrategia adecuada para conseguir su entendimiento cabal y tendiente a la resolución del mismo.

Com a ocor-rência de leucopenia febril inespecífica, foram associados ao tratamento antimi-crobianos e antifúngicos. A diminuição da função renal, observada inicialmente, contribuiu para a suspeita de síndrome de ATRA, que foi agravada pelos antifúngi-cos. Assim, o uso de ATRA foi suspenso, mas somente 8 dias depois foi caracteriza-da pneumonia e descartada a hipótese de síndrome de ATRA. Nesse contexto, foi discutida a nefrotoxicidade do ATRA e a potencialização desse efeito adverso pelo uso de antifúngicos nefrotóxicos, em par-ticular da anfotericina B, assim como a im-portância do diagnóstico diferencial entre síndrome de ATRA e doença infecciosa.

La osteomielitis aguda es una infección del hueso que afecta principalmente a los niños y tiene generalmente diseminación hematógena, a veces asociada a un trauma. En la etiología influyen factores, como la edad, el estado inmunológico y las enfermedades concomitantes. En la mayoría de los casos, el principal agente etiológico es Staphylococcus aureus. Es importante el diagnóstico oportuno para evitar secuelas a mediano o largo plazo. El objetivo de este estudio fue describir las características epidemiológicas de un grupo de pacientes con osteomielitis aguda. MÉTODOS: Se realizó la revisión retrospectiva de los expedientes clínicos de pacientes egresados del servicio de infectología del Hospital Nacional de Niños, en Costa Rica, entre agosto de 1994 y enero de 1995, con diagnóstico de osteomielitis aguda. RESULTADOS. Se registraron 49 egresos y se tabularon datos de 35 pacientes. El 65 % fueron varones; la edad media fue 7 ± 3,42 años y la estancia fue de 10,31 ± 5,55 días. Se aisló Staphylococcus aureus en el 28 % de los casos; Haemophilus influenzae en un caso (3 %, en sangre (hemocultivo positivo. No se aisló germen en el 57 % de los casos. Los sitios anatómicos afectados fueron principalmente la tibia (26 %, el fémur (20 % y el calcáneo (17 %. Fue utilizada oxacilina en el tratamiento de 30 de los 35 pacientes (86 % y la amikacina, en el 61 % de los casos. En las cepas de S. aureus se encontró una resistencia a la oxacilina del 7 %. CONCLUSIONES. Los hallazgos fueron similares a los reportados en la literatura en cuanto a etiología, sitio anatómico afectado y cobertura antibiótica. El clínico debe sospechar una osteomielitis aguda en todo niño con fiebre, dolor óseo e inflamación con afectación funcional, sea de aparición espontánea o asociada a trauma, para efectuar un diagnóstico oportuno y un tratamiento eficaz.INTRODUCTION.

    Bilateral anterior opercular syndrome is clinically characterized by facio-pharyngo-glossomasticatory diplegia due to bilateral opercular lesions. Reported cases of the syndrome have been relatively rare probably because of difficulty in determining opercular damage on clinical symptoms alone. We report a case of this syndrome in whom bilateral opercular damage could be detected not by CT, but suspected by SPECT, and confirmed by MR imaging.

    Full Text Available Introduction. Pathological dislocation of the hip is one of the most severe complications of acute hematogenous osteomyelitis. The program of treatment for children with pathological hip dislocation is complex, but it has been sufficiently developed and implemented very successfully. At the same time, the available literature provides no cases of treating children with bilateral pathological hip dislocations after hematogenous osteomyelitis. There is no information on the incidence of such cases or in regards to remote functional results. Materials and methods. The results of the treatment of 18 children with bilateral pathological dislocation of the hip after hematogenous osteomyelitis are presented, which constituted 23.1% of the total number of patients (78 who underwent surgery in 2000–2016 for the diagnosis of pathological hip dislocation. Both hip joints were surgically operated on in 12 patients, while one hip joint was operated on in 6 patients. To assess the anatomical and functional state of hip joints, the clinical and roentgenological diagnostic techniques were used. Results and discussion. To stabilize and restore the function of the hip joints, 18 children underwent 30 surgical interventions: simple open hip reduction (19 and open hip reduction with hip arthroplasty with one (6 or two (5 demineralized osteochondral allogeneic grafts. The decision regarding the possibility of performing surgical intervention on the second hip joint was made only after a child's check-up examination was complete and after positive information about the anatomical and functional state of the operated hip joint was obtained. According to these criteria, 14 (77.8% children underwent surgical treatment of the second hip joint 1–1.5 years after the course of conservative measures to restore the range of motion in the previously operated hip joint. Over a period of 1–12 years, 17 patients were examined, 10 of which underwent an operation on both

    The purpose of this study was to evaluate the interocular symmetry of several biometric parameters between both eyes. The symmetry between the right and left eye of 397 subjects in 14 biometric parameters, spherical equivalent of refractive error (SE), Jackson crossed cylinder power of refractive error astigmatism with axes at 90° and 180° (RJ0) and at 45° and 135° (RJ45), best-corrected visual acuity (BCVA), average corneal curvature (CC), Jackson crossed cylinder power of corneal astigmatism (CJ0 and CJ45), corneal asphericity coefficient (Q), intraocular pressure (IOP), central corneal thickness (CCT), axial length (AL), anterior chamber depth (ACD), lens thickness (LT) and vitreous chamber depth (VCD), was assessed by comparative data analysis. Aside from RJ0 (p = 0.00), RJ45 (p = 0.02) and Q (p = 0.00), the overall interocular differences of other biometric parameters between fellow eyes were not significant (p > 0.05). The interocular correlation and Bland-Altman plots showed a good agreement between fellow eyes in 14 biometric parameters. Correlations between interocular differences in SE and that in RJ0 (p = 0.03), CC (p = 0.00), AL (p = 0.00) and VCD (p = 0.00) were statistically significant. There were similar strong linear relationships between refractive error astigmatism vectors and corneal astigmatism vectors in bilateral eyes. There were negative correlations of RJ45 and CJ45 between bilateral eyes. A potentially clinically important interocular symmetry in SE, BCVA, CC, CJ0, CJ45, IOP, CCT, AL, ACD, LT and VCD is found in this research, while the differences of RJ0, RJ45 and Q between left and right eyes seem a bit large. The negative interocular relationships of RJ45 and CJ45 demonstrate moderate mirror symmetry exists among fellow eyes. High interocular symmetry in bilateral eyes may be helpful in intraocular lens power calculation, intraocular pressure evaluation, post-operative visual acuity and refraction

    Full Text Available Synchronous bilateral upper urinary tract urothelial cancer (UTUC is a very rare form of urothelial cancer. In patients with high-risk unilateral UTUC, radical nephroureterectomy (RNU is the gold standard treatment. However, there is no consensus on the treatment for synchronous bilateral UTUC. Evaluation of the patient and the tumor is recommended. Bilateral nephron-sparing surgery (NSS was performed on a 53-year-old patient who presented with high-risk synchronous bilateral UTUC, and the outcome was reported.

    Full Text Available Among infertile men, a diagnosis of unilateral varicocele is made in 90% of varicocele cases and bilateral in the remaining varicocele cases. However, there are reports of under-diagnosis of bilateral varicocele among infertile men and that its prevalence is greater than 10%. In this prospective study, we aimed to examine the differentially expressed proteins (DEP extracted from spermatozoa cells of patients with bilateral varicocele and fertile donors. Subjects consisted of 17 men diagnosed with bilateral varicocele and 10 proven fertile men as healthy controls. Using the LTQ-orbitrap elite hybrid mass spectrometry system, proteomic analysis was done on pooled samples from 3 patients with bilateral varicocele and 5 fertile men. From these samples, 73 DEP were identified of which 58 proteins were differentially expressed, with 7 proteins unique to the bilateral varicocele group and 8 proteins to the fertile control group. Majority of the DEPs were observed to be associated with metabolic processes, stress responses, oxidoreductase activity, enzyme regulation, and immune system processes. Seven DEP were involved in sperm function such as capacitation, motility, and sperm-zona binding. Proteins TEKT3 and TCP11 were validated by Western blot analysis and may serve as potential biomarkers for bilateral varicocele. In this study, we have demonstrated for the first time the presence of DEP and identified proteins with distinct reproductive functions which are altered in infertile men with bilateral varicocele. Functional proteomic profiling provides insight into the mechanistic implications of bilateral varicocele-associated male infertility.

    2018-02-01

    Full Text Available A 23-year-old man was transported to a trauma center after injuring himself while snowboarding. He presented with bilateral shoulder pain and associated deformity to both shoulders. His exam was otherwise unremarkable, and his x-rays confirmed bilateral shoulder dislocations. Cunningham and external rotation without sedation and analgesia techniques were unsuccessful even with local anesthesia to the joint. Subsequent bilateral reduction was successful with moderate sedation using the Milch technique. Simultaneous anterior bilateral shoulder dislocations are rare and providers may need to adjust their techniques to accommodate this unusual presentation.

    Full Text Available We report a case of rare bilateral massive ovarian luteinized follicular cysts in a twin pregnancy. A 28-year-old, gravida 1, para 0, abortus 0 woman was incidentally found to have bilateral massive ovarian cysts (left side, 12 × 10 × 8 cm; right side, 15 × 10 × 6 cm during the cesarean delivery of a twin pregnancy at 36 weeks of gestation. After 1,950-g and 2,350-g female babies were delivered in good condition, the patient received bilateral oophorectomy. Subsequent histopathology led to the diagnosis of giant bilateral ovarian luteinized follicular cysts.

    Sildenafil citrate (Viagra) is one of the frequently prescribed drugs for men with erectile dysfunction. We describe a 52-year-old man with bilateral middle cerebral artery (MCA) territory infarction after sildenafil use. He ingested 100 mg of sildenafil and about 1 h later, he complained of chest discomfort, palpitation and dizziness followed by mental obtundation, global aphasia and left hemiparesis. Brain magnetic resonance imaging documented acute bilateral hemispheric infarction, and cerebral angiography showed occluded bilateral MCA. Despite significant bilateral MCA stenosis and cerebral infarction, systemic hypotension persisted for a day. We presume that cerebral infarction was caused by cardioembolism with sildenafil use.

    Full Text Available Bilateral synchronous male breast cancer is very rare. A 63-year-old male presented with rapidly progressive enlarging bilateral breast masses without ulceration and bloody nipple discharge. Synchronous bilateral breast cancer was diagnosed by fine needle aspiration cytology. Pathology study revealed grade 2 invasive ductal carcinoma in both breasts. He underwent a bilateral modified radical mastectomy followed by chemotherapy and hormone therapy. The importance of this case report is to create increased attention to the fact that, although rare, breast cancer can occur in males. Early presentation and compliance with treatment modality provide a better outcome.

    Full Text Available Bilateral adrenal hemorrhage (BAH is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency.

    We report the case of a 57-year-old right-handed woman, with a history of hypertension, who, in February 1990, suddenly developed behavioral and cognitive abnormalities. Prior to the onset of her illness she had been normal. On examination, neuropsychological testing (Wechsler Mental Test, Wechsler Adult Intelligence Scale Revised, Knox Cube Test) elicited attention abnormalities, decreased recent memory, apathy, reduced spontaneity and initiative and left hemiparesia. CT scan showed small low density areas in the head of both caudate nuclei and right internal capsule, indicating infarction. Two years later, the deficit had partially resolved. Apathy persisted; psychometry showed an IQ of 57. Bilateral damage to the head of the caudate nuclei disrupt cortical-subcortical connections. The caudate nucleus is an essential component of basal ganglia-thalamo-cortical circuitry and its contribution to cognitive functions and behavior appears to be important.

    In light of growing water scarcity, virtual water, or the water embedded in key water-intensive commodities, has been an active area of debate among practitioners and academics alike. As of yet, however, there is no consensus on whether water scarcity affects conflict behavior and we still lack empirical research intending to account for the role of virtual water in affecting the odds of militarized disputes between states. Using quantitative methods and data on virtual water trade, we find that bilateral and multilateral trade openness reduce the probability of war between any given pair of countries, which is consistent with the strategic role of this important commodity and the opportunity cost associated with the loss of trade gains. We also find that the substantive effect of virtual water trade is comparable to that of oil and gas, the archetypal natural resources, in determining interstate conflicts' probability.

    1992-01-01

    Bilateral renal agenesis (BRA) is an uniformly lethal malformation occurring in 0.1-0.3/1000 births. This condition is associated with severe oligohydramnios, intrauterine growth retardation (IUGR), extra-renal anomalies, and malpresentation. The aim of this study was to present our experience with 10 cases of BRA seen in a 10-year period. In only one case the prenatal diagnosis was made. Therefore, the clinician was faced with a high-risk pregnancy: 70% of cases presented with malpresentation, oligohydramnios, and severe IUGR. This explain the high rate of cesarean section (40%) and the neonatal intensive care offered to these neonates. The principal methods to improve the prenatal diagnosis of this condition are discussed.

    Brown, Christopher A

    2014-01-01

    Bilateral cochlear implant (BCI) users receive limited binaural cues and, thus, show little improvement to speech intelligibility from spatial cues. The feasibility of a method for enhancing the binaural cues available to BCI users is investigated. This involved extending interaural differences of levels, which typically are restricted to high frequencies, into the low-frequency region. Speech intelligibility was measured in BCI users listening over headphones and with direct stimulation, with a target talker presented to one side of the head in the presence of a masker talker on the other side. Spatial separation was achieved by applying either naturally occurring binaural cues or enhanced cues. In this listening configuration, BCI patients showed greater speech intelligibility with the enhanced binaural cues than with naturally occurring binaural cues. In some situations, it is possible for BCI users to achieve greater speech intelligibility when binaural cues are enhanced by applying interaural differences of levels in the low-frequency region.

    2007-02-01

    We report a rare case of major trapezometacarpal instability observed in a 31-year-old woman with congenital hyperlaxity. The patient presented major functional impotency of both thumbs, closure of the first commissure, and absence of effective opposition except between the lateral borders of the long fingers due to severe pain in the trapezometacarpal joint attributed to osteoarthritis. The patient underwent bilateral trapezectomy with ligamentoplasty. The gross examination of the trapezeal specimens revealed major cartilage destruction on the medial portion of the trapezeal joint surface. Three months after surgery, the patient was able to resume occupational and recreational activities. At one year, she was pain free with normal function. No other similar case could be identified in the literature and search for a pathological condition which could have contributed to the altered collagen was negative. It was observed that since stabilization was achieved by ligamentoplasty, recurrence should not be expected in congenital hyperlaxity if the tendons are unaffected.

    Full Text Available X-linked juvenile retinoschisis is a rare hereditary retinal disease characterized by a tangential splitting of the neurosensory retina which may cause early-onset visual impairment. Existence of the retinal neurosensory layer splitting on cross-sectional images of optical coherance tomography (OCT and the absence of leakage on fluorescein angiography (FA help confirming the diagnosis. Such diagnostic tests are also helpful in determining the management of the disease. However, most of the retinoschisis cavities remain stable and rarely extend to the posterior pole, many authors suggest laser prophylaxis to avoid the potential risk of retinal detachment due to holes in the outer retinal layer. Herein, we report a case with bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis who was evaluated with detailed ophthalmologic examination. Visual acuity, fundoscopy, OCT, and FA remained stable in the second year of follow-up after prophylactic argon laser treatment.

    male breast cancer is a disease with low incidence, which is further reduced when it comes to bilateral synchronous presentation. There are few published cases in recent years. The aim is to establish guidelines for the management of this disorder that is so rare. a 75-year-old with tumors in both breasts, which were completely resected with removal of palpable nodes. The histopathological study reported ductal carcinoma. The indicated treatment was adjuvant tamoxifen and radiotherapy. The patient is currently in a disease-free period. this is a rare disease, whose main treatment is surgery, hence the importance of early diagnosis. Most cases require adjuvant chemotherapy and radiotherapy because they are usually diagnosed at an advanced stage.

    2015-01-01

    Abstract Cherubism is a rare, nonneoplastic, self-limiting fibro-osseous that occurs in children. Affected children usually appear normal at birth. Lesions are characterized by the replacement of bone with fibrovascular tissue containing many multinucleated giant cells. Most studies have reported cherubism to be familial and with bilateral involvement of the mandibles. The authors describe a nonfamilial case of cherubism, involving both the mandible and the maxilla, in a 4-year-old female child with slowly enlarging, painless, symmetrical swelling of both cheeks. Cherubism is a rare disease that is usually limited to the mandible, but the maxilla may be involved. Computed tomography scan and biopsy are helpful for early diagnosis. PMID:26656340

    2012-01-01

    We report a case of bilateral traumatic expulsive aniridia after uneventful phacoemulsification through small clear corneal incisions. Phacoemulsification was performed 8 and 13 months prior to the trauma in the left and right eyes, respectively. In both eyes, the intraocular lens and capsular bag were undisturbed after trauma. After resolution of hyphema, transient elevated intraocular pressure, and anterior chamber inflammation, best corrected visual acuity returned to 20/25 in each eye 6 months later. Self-sealing clear corneal wounds likely serve as a decompression valve during blunt trauma, thus preventing devastating intraocular damage and globe rupture. The intraocular lens may absorb the external force, therefore preventing damage to the capsular bag and zonules as well as preventing prolapse of posterior structures. A review of previously reported cases of traumatic aniridia is also presented.

    2013-01-22

    Taurodontism is a rare dental anomaly in which there is an enlarged pulp chamber at the expense of roots with apical displacement of the pulpal floor, giving it a rectangular shape. It is caused by the failure of Hertwig's epithelial root sheath to invaginate at the proper horizontal level. Taurodontism has been reported as an intraoral feature of several syndromes like Down syndrome, Klinefelter syndrome, Smith-Magenis syndrome, Hurler syndrome, etc. Association of taurodontism with hypodontia in permanent dentition has also been reported. Taurodontism in primary dentition and its association with hypodontia is very rarely reported in the literature. The present case illustrates bilateral taurodontism of primary mandibular molars with hypodontia in maxilla.

  12. Rhinoscleroma causing severe bilateral nasal obstruction

    Directory of Open Access Journals (Sweden)

    Mário Augusto Pinto de Moraes

    Full Text Available Rhinoscleroma is a chronic, infectious and granulomatous disease of the respiratory tract. There is often a delay in diagnosis due to unfamiliarity with the disease and also because culture is not always positive. We report a case in a 26-year-old woman with granular mass obstructing bilateral nasal cavities and causing breathing difficulty. Histopathological examination showed characteristic Mikulicz histiocytes containing numerous Gram-negative intracellular rod-shaped bacilli consistent with the diagnosis of rhinoscleroma. The patient was treated with gemifloxacin and tetracycline and remains asymptomatic over a year follow-up period. It is important to consider rhinoscleroma in cases of chronic nasal obstruction. As culture is not always positive, histopathological examination may be crucial to the diagnosis.

    Full Text Available Vernal Keratoconjunctivits (VKC is a bilateral recurrent allergic interstitial conjunctival inflammation with a periodic seasonal incidence and of self limiting nature, mainly affecting the younger population. Patients of VKC on steroid therapy are at higher risk of developing steroid induced glaucoma. Raised intraocular pressure due to steroids typically occurs within few weeks of starting steroid therapy and comes back to normal on immediate stoppage of steroids. A case of steroid induced glaucoma in a 30 years old female with vernal keratoconjunctivitis. She was on topical steroids for 3-4 years. She was incompliant with the instructions to stop steroids. She eventually developed steroid induced glaucoma and glaucomatous optic neuropathy with tunnel vision.

    The ultimobranchial bodies in human embryos develop from the fourth and fifth branchial pouch complexes along with thymic and parathyroid tissue. They become incorporated within the lateral thyroid lobes and are believed to be involved in the development of C-cells. We report a case of an unusual bilateral thyroid and neck prelaryngeal medullary carcinoma in a 23-year-old male patient who belongs to a multiple endocrine neoplasia type 2a (MEN type 2a) family with thyroid tumors and pheochromocytomas. The medullary carcinoma was located in an abnormal cystic structure that seems to be a remnant of the ultimobranchial body (UBB) in the neck. Within the contralateral thyroid lobe, the medullary carcinoma was associated with C-cell hyperplasia.

    1995-12-01

    The paper describes the implementation of shared control in a force reflecting telerobotic system which has been carried out during the EC TELEMAN project INGRID. The experimental facility which has been developed at Newcastle comprises a Puma 762 robot which can be manually teleoperated by a Puma 260 robot, functioning as a generalized bilateral (or force reflecting) controller. The slave robot has been configured to support several autonomous force controlled tasks, which have been developed specifically for repair and maintenance operations in nuclear and/or other hazardous environments. The control architecture is based on a network of parallel processors, and the man-machine interface provides `soft-switching' of any axis to facilitate mixed mode and shared control which can be configured in both teleoperator and task based modes. A graphic display is also included to provide a visual indication of the magnitude of forces/torques exerted at the tool/environment interface.

    2010-01-01

    Full Text Available Perinephric lymphangioma is rare disorder that may be confused with various forms of renal cystic diseases and urinomas. In this disorder a developmental malformation results in failure of developing lymphatic tissue to establish normal communication with the rest of lymphatic system. Once there is restricted drainage of lymphatic fluid the lymphatic channels dilate to form cystic masses that may be unilocular or multilocular and may be seen unilaterally or bilaterally .This condition presents with various signs and symptoms or can be just an incidental finding which in presence of misleading clinical history may be confused with other diseases. CT scan with delayed cuts and USG guided aspiration with biochemical analysis of fluid will help us in arriving to final diagnosis.

    Regidor, J; Divac, I

    1992-01-01

    In adult hedgehogs with large unilateral cortical deposits of fluorescent somatopetal tracers, labelled perikarya were found not only in the ipsilateral but also contralateral thalamus. An exceptionally large number of contralaterally labelled neurons was seen in the ventrolateral nucleus, also at a considerable distance from the midline. Deposits of one of two different tracers in the frontoparietal cortex of each hemisphere appear to label different perikarya in each ventrolateral nucleus. This projection to the contralateral cortex in hedgehogs does not resemble thalamo-cortical connections in either adult or developing brains of other mammalian species. Among amniotes, only in pigeons have contralateral projections from the thalamus to the telencephalon been described. The somatosensorimotor system of hedgehogs may be the only known mammalian remnant of primitive vertebrate thalamocortical organization. Whether primitive or derived, the bilateral thalamocortical projection in hedgehogs shows that hedgehog brains cannot be uncritically taken to represent brains of primate ancestors.

    2015-12-01

    Full Text Available Pigmented villonodular synovitis is a disorder resulting in a villous, nodular, or villonodular proliferation of the synovium, with pigmentation related to the presence of hemosiderin. These lesions are almost exclusively benign with rare reports of malignancy. Pigmented villonodular synovitis can occur in a variety of joints and at any age but most often occurs within the knee in the young adult. Pigmented villonodular synovitis is a rare disease entity, and bilateral synchronous or metachronous involvement of a joint is even more uncommon, with few reports previously described in the literature. We present a case of pigmented villonodular synovitis involving both the right and left knee in the same patient, with radiographic imaging, magnetic resonance imaging, photograph and video intraoperative imaging, and pathologic correlation.

    Vos, F I; Merkus, P; van Nieuwkerk, E B J; Hensen, E F

    2016-10-08

    In this paper, we describe the case of a 62-year-old female with recurring episodes of sudden deafness with vertigo and facial paresis. Within a month's time, this resulted in bilateral deafness and vestibular areflexia. Erroneously, the patient was diagnosed with sudden deafness of unknown origin and subsequently with neuroborreliosis (Lyme disease). The true diagnosis of relapsing polychondritis (RP) was revealed 9 months after initial presentation. The diagnostic delay is in part explained by the fact that, by definition, the disease has to relapse before the diagnosis can be made, but also by its pluriform clinical presentation. Timely identification of RP as the cause of this profound sensorineural hearing loss proved to be important. It was key in instigating adequate follow-up, and allowed for cochlear implantation before total cochlear obliteration, which might have hampered optimal hearing rehabilitation. 2016 BMJ Publishing Group Ltd.

  1. Bilaterally Weighted Patches for Disparity Map Computation

    Directory of Open Access Journals (Sweden)

    Laura Fernández Julià

    2015-03-01

    Full Text Available Visual correspondence is the key for 3D reconstruction in binocular stereovision. Local methods perform block-matching to compute the disparity, or apparent motion, of pixels between images. The simplest approach computes the distance of patches, usually square windows, and assumes that all pixels in the patch have the same disparity. A prominent artifact of the method is the "foreground fattening effet" near depth discontinuities. In order to find a more appropriate support, Yoon and Kweon introduced the use of weights based on color similarity and spatial distance, analogous to those used in the bilateral filter. This paper presents the theory of this method and the implementation we have developed. Moreover, some variants are discussed and improvements are used in the final implementation. Several examples and tests are presented and the parameters and performance of the method are analyzed.

    2006-01-01

    Münchausen syndrome is a factitious disorder in which patients knowingly harm themselves for subconscious psychological reasons in order to be hospitalized. Recognition of this psychopathology is important, to prevent potentially severe eye damage. Ocular Münchausen syndrome is uncommon. The authors describe an elderly woman with recurrent, probably self-induced, ocular trauma leading to bilateral blindness. The authors are unaware of any previously reported cases of Münchausen syndrome resulting in bilateral blindness and occurring in old age. A 73-year-old woman was first seen in 1991 with a closed-globe injury to the right eye, apparently following a household fall. Physical examination showed no sign of extraocular trauma. Right visual acuity was 20/30 after 2 months. She was readmitted in May 2003 with left globe rupture, allegedly following a domestic fall. No extraocular trauma was found. She developed ocular phthisis 6 months postoperatively. The patient was admitted again in February 2004 with right globe rupture, following another alleged domestic fall. Physical examination showed no sign of extraocular trauma. Right visual acuity was 20/400 2 months postoperatively. Psychiatric evaluation revealed Münchausen syndrome. Psychotherapy was prescribed, but refused by her family. Diagnosis of Münchausen syndrome is difficult to make in the ophthalmic department. Münchausen patients have little or no ability to control their self-destructive behavior. A sympathetic and supportive approach is therefore required and these patients should be urgently referred to a psychiatrist with experience in factitious disorders. Even with psychotherapy, which is often refused, the prognosis remains poor.

    Full Text Available Acute pyelonephritis complicates 1-2% of pregnancies and causes significant maternal and fetal morbidity and mortality. The diagnosis of renal tuberculosis (TB is often delayed and commonly presents with sterile pyuria or along with other pyogenic organisms. We report a case where the diagnosis of renal TB was missed in a pregnant woman when she presented with acute pyelonephritis, septic shock, and acute renal failure. There was clinical recovery with antibiotics, but bilateral psoas and perinephric abscesses (TB, Enterococcus sp., and E. coli were diagnosed when she presented with loin pain and palpable left renal angle swelling. Bilateral psoas abscess due to TB in the absence of skeletal TB and human immunodeficiency virus infection is rare. The presentation of renal TB in pregnancy, its complications, and its management are discussed.

    Full Text Available Espasmo hemifacial bilateral é um distúrbio de movimento raro geralmente associado à compressão vascular dos nervos faciais. Caracteriza-se clinicamente por contrações assimétricas e assíncronas da musculatura facial e por longa latência entre a instalação dos movimentos em cada hemiface. Deve ser diferenciado de outras condições como blefaroespasmo, miocimia facial, tiques faciais, distonia oromandibular e espasmo hemimastigatório. O tratamento sintomático mais eficaz e menos invasivo consiste em aplicações de toxina botulínica mas abordagem cirúrgica de descompressão microvascular é outra alternativa terapêutica. Relatamos o caso de homem de 70 anos com espasmo hemifacial bilateral e fazemos uma breve revisão da literatura.Bilateral hemifacial spasm (BHS is a rare focal movement disorder often associated with vascular compression of both facial nerves. The contractions are usually asymmetric and asynchronous. Typically, one side is affected first and there is a long but variable interval for the symptoms on the other side to occur. BHS must be differentiated from other conditions including blefarospasm, facial myokymia, facial tics, oromandibular dystonia, and hemimasticatory spasm. The most successful and non-invasive symtomatic treatment is botulinum toxin injections but microvascular decompression surgery is another therapeutic option. We report the case of a 70 years old man with bilateral hemifacial spasms and present a brief review of the literature.

    Full Text Available Relata-se o caso de um paciente com dispnéia intensa ao se deitar, em que foram excluídas doenças pulmonares, neuromusculares ou cardíacas, cuja investigação revelou paresia diafragmática bilateral. Um sinal chave para o diagnóstico foi a evidência de respiração paradoxal com o doente em decúbito supino. Havia piora da oxigenação e da capacidade vital forçada com a mudança da posição ortostática para supina. A fluoroscopia ortostática foi normal. A pressão inspiratória máxima estava muito reduzida. A estimulação elétrica transcutânea do diafragma foi normal, e a eletroestimulação do nervo frênico mostrou ausência de resposta, permitindo o diagnóstico de paresia bilateral do diafragma.We report the case of a patient with severe dyspnea upon reclining. Lung disease, neuromuscular disorders and heart disease were ruled out. However, during the course of the investigation, bilateral diaphragmatic paresis was discovered. A key sign leading to the diagnosis was evidence of paradoxical respiration in the dorsal decubitus position. When the patient was moved from the orthostatic position to the dorsal decubitus position, oxygenation and forced vital capacity worsened. The orthostatic fluoroscopy was normal. Maximal inspiratory pressure was severely reduced. The responses to transcutaneous electric stimulation of the diaphragm were normal. However, electric stimulation of the phrenic nerve produced no response, leading to the diagnosis of bilateral diaphragmatic paresis.

    Full Text Available Objetivos: Describir las principales manifestaciones electrocardiográficas observadas durante la fase aguda de la enfermedad cerebrovascular isquémica. Métodos: Estudio descriptivo transversal prospectivo en 132 pacientes ingresados en la Unidad de Cuidados Intermedios del Hospital General Docente Vladimir Ilich Lenin, provincia de Holguín, con enfermedades cerebrovasculares isquémicas del periodo comprendido entre febrero de 2013 a febrero de 2015. Resultados: Predominó el sexo masculino (59,1%. El principal factor de riesgo (84,8% resultó ser la hipertensión arterial, seguida de la cardiopatía isquémica (34,8% y de la diabetes mellitus (22,7%. La muestra presentó un 33,3% de antecedentes y se complicó el 57,6%. El trastorno electrocardiográfico más frecuente secundario a la lesión isquémica cerebral fue la taquicardia sinusal (34,8% seguida de los extrasístoles (21,2%. Conclusiones: El sexo masculino y la existencia de enfermedad cardiaca previa constituyen factor predisponente a la aparición de las complicaciones definidas de alteraciones cardiovasculares durante la fase aguda del ictus. La hipertensión arterial constituye el factor de riesgo modificable principal en la enfermedad cerebrovascular isquémica tanto en el eje carotídeo como vertebrobasilar. Los pacientes con ictus del territorio carotídeo tienen un mayor riesgo de padecer alteraciones cardiovasculares durante la fase aguda que los pacientes con ictus del territorio vertebrobasilar. Las principales alteraciones del ritmo encontradas en los pacientes estudiados fueron la taquicardia sinusal, las extrasístoles ventriculares y las extrasístoles auriculares.

    Background The current treatment intervention study determined the effect of coupled bilateral training (i.e., bilateral movements and EMG-triggered neuromuscular stimulation) and resistive load (mass) on upper extremity motor recovery in chronic stroke. Methods Thirty chronic stroke subjects were randomly assigned to one of three behavioral treatment groups and completed 6 hours of rehabilitation in 4 days: (1) coupled bilateral training with a load on the unimpaired hand, (2) coupled bilateral training with no load on the unimpaired hand, and (3) control (no stimulation assistance or load). Results Separate mixed design ANOVAs revealed improved motor capabilities by the coupled bilateral groups. From the pretest to the posttest, both the coupled bilateral no load and load groups moved a higher number of blocks and demonstrated more regularity in the sustained contraction task. Faster motor reaction times across test sessions for the coupled bilateral load group provided additional evidence for improved motor capabilities. Conclusions Together these behavioral findings lend support to the contribution of coupled bilateral training with a load on the unimpaired arm to improved motor capabilities on the impaired arm. This evidence supports a neural explanation in that simultaneously moving both limbs during stroke rehabilitation training appears to activate balanced interhemispheric interactions while an extra load on the unimpaired limb provides stability to the system.
