    2002-08-01

    Full Text Available Los eventos tromboembólicos son complicaciones poco frecuentes del tratamiento hormonal de la infertilidad y generalmente están asociados al síndrome de hiperestimulación ovárico (SHO. La trombosis venosa yugular es infrecuente y ante su presencia se debería sospechar la existencia de algún factor predisponente. Describimos una paciente de 31 años, sin antecedentes de importancia, no fumadora, a la cual se le realizó un único ciclo de estimulación hormonal para fertilización in vitro por esterilidad primaria con factor masculino. Durante la octava semana de embarazo gemelar desarrolló una trombosis yugular interna bilateral, en ausencia de SHO u otros factores predisponentes aparentes. En la evaluación para trombofilia se detectó la presencia del Factor V Leiden y la mutación del gen de la protrombina G 20210, que junto con el estímulo hormonal, se interpretaron como los factores predisponentes. Se anticoaguló con heparina de bajo peso molecular. No está recomendado el rastreo sistemático de trombofilia antes del tratamiento hormonal, pero podría ser considerado en pacientes de alto riesgo o en quienes desarrollan trombosis en ausencia de un factor predisponente claro.Thromboembolic events are an infrequent complication of hormonal treatment for infertility and are generally related to the hyperstimulated ovarian syndrome (HOS. Jugular vein thrombosis is an unusual site of thrombosis and when present one should look for a predisposing factor. We describe a 31-year-old woman, with no previous medical history, non-smoker, who received a single cycle of hormonal stimulation for in vitro fertilisation due to primary infertility. During her eighth week of a twin pregnancy, she consulted the emergency room where the diagnosis of bilateral jugular thrombosis was confirmed, in absence of HOS or any known predisposing factor. In subsequent studies, the presence of Factor V Leyden and a mutation of G 20210 prothrombin were found

    Full Text Available Objetivos. Determinar las características clínicas y microbiológicas de las infecciones del tracto urinario asociadas acatéter (ITUAC en pacientes hospitalizados en los servicios de Medicina Interna del Hospital Universitario de Los Andes (HULA, Mérida, Venezuela y establecer la distribución clonal de Enterobacteriaceae multirresistentes productoras de esta infección. Materiales y métodos. Se estudiaron 73 pacientes adultos con cateterismo vesical, durante enero a julio de 2015. El procesamiento microbiológico de las muestras de orina se realizó por métodos convencionales y automatizados. Las β-lactamasas de espectro extendido (BLEE y carbapenemasas fueron detectadas fenotípicamente. La tipificación clonal se determinó por la amplificación de secuencias repetitivas por PCR. Resultados. El 53,4% de los pacientes eran varones, con una edad media de 50,6 años. El promedio de permanencia del catéter fue de 10,9 + 6,5 días/paciente. El 54,8% de los pacientes tuvo urocultivos positivos. Las levaduras fueron el principal agente etiológico (44,7%, seguido por las enterobacterias (29,8%. Las enterobacterias, Pseudomonas aeruginosa y Acinetobacter baumannii produjeron BLEE y carbapenemasas asociadas a otros marcadores de resistencia. Dos grupos clonales fueron identificados en cepas de E. coli y K. pneumoniae multirresistentes, los cuales circularon en la unidad de trauma shock de la emergencia de adulto. Conclusiones. Los hallazgos de este estudio permiten evidenciar la necesidad de adoptar estrictos criterios que justifiquen el uso del catéter vesical y la duración del mismo, así como el implementar programas para prevenir y controlar la diseminación de clonas bacterianas multirresistentes en pacientes con ITUAC en los servicios de medicina interna del HULA.

    Full Text Available Relatamos um caso de obstrução bilateral na origem das artérias carótidas internas, apresentando como sinais/sintomas associados hemiparesia e hipoestesia superficial e profunda à direita, associada a sífilis meningovascular em paciente com SIDA. Tomografia de crânio apresentou pequenas lesões hipodensas, com predomínio à esquerda, e arteriografia evidenciou oclusão bilateral das artérias carótidas. A associação entre lues e SIDA não é infrequente, porém o quadro oligossintomático do paciente, provavelmente devido a oclusão arterial lenta e gradual chama a atenção.We report a case of bilateral occlusion of internal carotid arteries ,presenting with right hemiparesis and hypoesthesia, associated to meningovascular syphilis in a patient with AIDS. CT scan showed few small hypodense lesions, with a predominance on the left side, and the angiography showed bilateral occlusion of the carotid arteries. The association between syphilis and AIDS is not unusual, but the paucity of symptoms, probably due to a slow and gradual occlusion is not commonly reported.

    Full Text Available OBJETIVO: Analisar os resultados de 15 pacientes com elevado risco de sangramento obstétrico, submetidas ao implante de catéteres balão profilático para oclusão temporária das artérias hipogástricas. MÉTODOS: Uma análise retrospectiva foi realizada com base em prontuários de 15 pacientes submetidas ao implante de catéteres balão profilático, de janeiro/2008 a dezembro/2011. Todas as pacientes incluídas no estudo foram diagnosticadas no período antenatal com doença placentária associada a alto risco de hemorragia obstétrica. RESULTADOS: A média de idade das pacientes estudadas foi de 36 anos (32-42 anos. Nove pacientes eram portadoras de acretismo placentário, quatro possuíam placenta prévia, uma estava com gestação ectópica e uma apresentava miomatose uterina e coagulopatia associada a Lupus Eritematosos Sistêmico. O volume total de contraste utilizado para o procedimento variou entre 20 e 160 ml (média de 84 ml. A média do número total de dias de internação e o número de dias de internação após o procedimento foram, respectivamente, 12,4 e 4,9 dias. Em oito (53% casos, não houve necessidade de transfusão sanguínea no intraoperatório ou após a cirurgia. A média do número de unidades de sangue transfundida foi 2,06. A única complicação associada ao procedimento foi a trombose arterial de artéria ilíaca externa, observada em dois casos. CONCLUSÃO: A oclusão temporária de artérias hipogástricas é um método seguro e efetivo para controle de hemorragia em pacientes com elevado risco de sangramento obstétrico, quando realizado por equipe experiente. Os resultados deste estudo são observacionais, retrospectivos e não randomizados; portanto, não podemos apoiar o uso rotineiro dessa técnica, mas podemos incluí-la no arsenal de recursos para casos selecionados com potencial para sangramento.

    2016-07-01

    Full Text Available La academia ha venido documentando un creciente número de modalidades de violencia sexual asociadas a los conflictos, sus causas y la gran variabilidad que existe en cuanto a su ejecución por parte de las organizaciones armadas. En este trabajo resumo los resultados de investigaciones recientes sobre dicha variabilidad, con énfasis en los hallazgos que contradicen o complican las creencias populares. Luego, presento varias interpretaciones sobre la afirmación de que esa violencia es parte de una continuidad entre tiempos de paz y de guerra. Después de analizar las investigaciones recientes sobre las dinámicas internas de las organizaciones armadas, sugiero que las violaciones sexuales a gran escala a menudo ocurren como una práctica, en vez de una estrategia. Por último, propongo algunos principios para guiar las políticas en vista de las investigaciones recientes

    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 La sífilis es una infección crónica y multisistémica, producida por la espiroqueta Treponema pallidum. Las manifestaciones oculares de la sífilis son varias y pueden afectar todas las estructuras oculares. La uveítis es el tipo de afectación ocular más frecuente. Puede presentarse en la fase secundaria, latente o terciaria y cursa de forma bilateral en el 50 % de los casos. También puede verse asociada al virus de inmunodeficiencia humana. Desde la introducción de la terapia antirretroviral de gran actividad, la mortalidad asociada al SIDA disminuyó y la incidencia de sífilis y otras enfermedades de trasmisión sexual aumentó como consecuencia de la expansión de la población homosexual. Teniendo en cuenta la gran variedad de formas de presentación, se le conoce como la gran simuladora y forma parte del diagnóstico diferencial de cualquier uveítis. Presentamos el caso de un paciente masculino de 64 años de edad que acude al Cuerpo de Guardia, donde refiere visión borrosa del ojo derecho de aproximadamente 45 días de evolución, asociado a enrojecimiento ocular, dolor y molestias a la luz, a quien posteriormente se le diagnóstico una uveítis sifilítica asociada al virus de inmunodeficincia humana.

    Hyperostosis frontalis interna is a morphological pattern characterized by single or multiple bony nodules situated on the inner lamina of the frontal bone. It is seldom found in males, but it is a common phenomenon among post-menopausal females in modern societies but relatively rare in antiquity. The etiopathogenesis of the trait is a matter of debate and ranges from genetic predisposition to epigenetic, while endocrine disturbances, aging, and dietary factors are also listed among the causes. We studied the frequency, characteristic features, and etiopathogenesis of the disease in recent cadaveric and dry skull specimens. The frequency of hyperostosis frontalis interna in cadavers and dry skull materials was almost identical, 12.5% and 12.3%, respectively. In cadavers, 87.5% of severe hyperostosis frontalis interna cases were found in females over 65 years-old. Interestingly, in two cadavers we found hyperostotic lesions spreading onto adjacent tissues such as the dura and falx cerebri. We provide some new aspects that may help in better understanding of the etiopathogenesis of hyperostosis frontalis interna. Thereby, we discuss the various etiopathogenesis models found in the literature. Copyright © 2011 Elsevier GmbH. All rights reserved.

  13. Agenesia sacra asociada a disrrafismo espinal e hidrocefalia

    Lisett Hernández León

    Full Text Available Introducción: la agenesia sacra es una malformación congénita rara que forma parte del síndrome de regresión caudal. Se caracteriza por un grupo de anomalías en las cuales la columna caudal está ausente. Esta enfermedad es la malformación más frecuente en los hijos de madres diabéticas, además se ha relacionado con otros factores predisponentes, como deficiencias de ácido fólico, de vitaminas, uso de insulina en el embarazo, e incluso, la hipoxia. Entre un 30-40 % de pacientes con agenesia sacra completa, pueden tener asociado un mielomeningocele, y el desplazamiento de las raíces nerviosas empeora los trastornos neurológicos. En estos casos, la hidrocefalia, muchas veces también asociada a malformación Chiari tipo II, está ya presente al nacer. Caso clínico: se presenta el caso de un neonato con agenesia sacra asociada a disrrafismo espinal e hidrocefalia. La intervención quirúrgica fue precoz, se le colocó derivación ventrículo peritoneal y se realizó la reparación del defecto del tubo neural. La evolución posoperatoria fue favorable, aunque persistieron los déficits neurológicos preoperatorios. Conclusiones: no se hallaron factores predisponentes en este paciente y el análisis del cariotipo fue normal. Las anomalías óseas de miembros inferiores fueron las más llamativas, así como la presencia de hidrocefalia asociada a malformación Chiari tipo II y mielomeningocele. El tratamiento a estos casos requiere de un enfoque multidisciplinar, y la reparación quirúrgica del mielomeningocele debe ser precoz para conseguir una evolución favorable. Las formas graves pueden ocasionar una muerte temprana neonatal, en cambio, los niños que sobreviven, generalmente presentan inteligencia normal.

  14. Síndrome Gorlin-Goltz asociado a fisura labiopalatina bilateral

    Directory of Open Access Journals (Sweden)

    Noemí Lorena Leiva Villagra

    Full Text Available El síndrome de Gorlin-Goltz corresponde a un trastorno de herencia autosómica dominante. Uno de los criterios menores de este síndrome es la fisura labiopalatina. Si bien esta corresponde a la anomalía congénita maxilofacial más prevalente, un porcentaje variable está asociado a síndromes. Presentar un caso de un paciente con síndrome de Gorlin-Goltz y fisura labiopalatina bilateral asociada constituye el propósito de esta presentación. Se trata de un paciente de 12 años de edad, con diagnóstico de síndrome de Gorlin-Goltz remitido por genetista. Clínicamente presenta anomalías cutáneas, óseas, dentarias, neurológicas, tumores, hoyuelos palmoplantares, prognatismo mandibular y fisura labiopalatina bilateral operada. Es importante reconocer las características asociadas no solo al área craneofacial, sino también a otras partes del cuerpo. Se requiere de la atención de un equipo multidisciplinario en el que el odontólogo también debe participar. La mayoría de las publicaciones se enfocan solo en el manejo quirúrgico de los quistes y no en el de otras secuelas asociadas, como lo es la fisura labiopalatina.

    To analyze the demographics, risk factors, clinical and microbiological characteristics of cases of bilateral simultaneous infective keratitis. In this retrospective case series, patients with clinical evidence of bilateral simultaneous infective keratitis were identified from January 1, 2011 to August 31, 2016. Demographics, risk factors, clinical and microbiological characteristics, and treatment outcomes were analyzed. Five patients (ten eyes) with bilateral simultaneous infective keratitis were identified. The mean age was 32.8 years (SD,±8.8; range, 24-44). All the patients were disposable soft contact lens wearers before presentation. The average size of the infiltrate was 4.76mm 2 (SD±9.0; range, 0.2-31.34). A total of 4 types of bacteria were isolated, with Pseudomonas aeruginosa being the most frequently isolated bacteria involving 5 eyes of four patients. Infection resolved with medical treatment in 9 eyes, 1 patient required therapeutic corneal transplantation for impending corneal perforation. The average time taken for infection to resolve was 6.7days (SD±4.5; range, 2-16). In this case series, the most common risk factor of bilateral simultaneous microbial keratitis was use of soft disposable contact lens and the most commonly isolated bacteria was Pseudomonas aeruginosa. Bilateral simultaneous infective keratitis is uncommon and is a serious complication of contact lens use in immunocompetent adult patients. Copyright © 2017 British Contact Lens Association.

    Full Text Available Se describe la displasia de Mondini asociada a pérdida auditiva y meningitis bacteriana recurrente. La malformación de Mondini representa el 30 % de las anomalías congénitas del oído interno, puede ser unilateral o bilateral, y su principal característica consiste en el desarrollo coclear incompleto, causante de grados variables de hipoacusia neurosensorial. Se considera que la ocurrencia de esta malformación se produce por disrupción del desarrollo embrionario durante la séptima semana de gestación, en la cual se detiene el desarrollo coclear. Se presenta el caso de una niña de 12 años, atendida en los Servicios de Pediatría y Otorrinolaringología del Hospital Pediátrico Universitario "William Soler", por presentar 3 infecciones meningoencefálicas, en las cuales se aisló Streptococcus pneumoniae serotipo 19F, y se constató hipoacusia neurosensorial severa en el oído izquierdo. La tomografía axial computarizada de alta resolución del oído (cortes axiales y coronales, evidenció la malformación coclear y vestibular, con presencia de tejido en el oído medio que se comunicaba directamente con el oído interno del lado izquierdo a nivel de la ventana oval. Se destaca la importancia de la sospecha clínica de displasia de Mondini, y el impacto científico de la tomografía computarizada del hueso temporal, para el diagnóstico precoz de fístula congénita en el oído interno asociada a meningitis bacteriana recurrente.

    1986-01-01

    In a series of 56 staged bilateral carotid endarterectomies, new neurologic symptoms developed in 5% and 20% following the first and second procedure, respectively. All complications were transient or minor. The incidence of postendarterectomy hypertension was significantly higher following...... the second procedure, when operations were staged less than 3 weeks apart. A correlation between these hypertensive episodes and the occurrence of new neurologic symptoms could not be shown. However, as this correlation has been proved in several other reports, bilateral carotid endarterectomy is advised...... to be staged at least 3 weeks apart. In addition, a conservative attitude towards contralateral asymptomatic lesions is proposed....

    An intraosseous ganglion is a relatively uncommon, benign, cyst-like lesion that occurs in young and middle-aged adults. Most commonly seen adjacent to the hip, ankle, knee, or wrist, they are histologically identical to their soft tissue counterparts. A review of the literature revealed only two previously reported examples of bilateral symmetrical ganglia of the lunate bones. (orig.)

    We evaluate 311 breast cancer patients admitted to Yong Dong Severance Hospital Between October 1st 1985 and July 31th 1989, and were able to obtain the following conclusions. 1) There were 14(4.5%) bilateral breast cancers among the 311 confirmed breast cancers. 2) Among the bilateral breast cancers, 5(31%) were synchronous and 9(69%) metachronous. 3) Average interval between the first and the second breast cancer in metachronous cancers was 3.8 year(1-15 years). 4) Bilateral breast cancer was most prevalent in the fifth decade (6/14) with the mean age of 47 years. 5) Film mammogram and sonomammogram showed findings of typical breast malignancies. There was no additional specific findings for each cancer in bilateral breast cancers which was different from unilateral cancers. Therefor, in the patients with unilateral breast cancer, possibility of the second lesion in the contralateral side must be considered and a close follow up observation should be done for at least 3 years

    Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968—May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V—Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed. ImagesFig. 1Fig. 4Fig. 6Fig. 7 PMID:4845653

    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.

    Twenty children with bilateral Wilms' tumor were presented to the Children's Hospital Medical Center and Children's Cancer Research Foundation, Sidney Farber Cancer Institute, and Joint Center for Radiation Therapy (CHMC-CCRF, SFCI, JCRT) from January 1, 1956 to December 31, 1976. Of these 20, 16 had simultaneous and 4 had metachronous disease on presentation. All patients were treated with surgery, radiation and chemotherapy. Of the 16 patients with simultaneous disease, 10 (63%) are alive and free of disease 12+ to 175+ months post diagnosis and treatment, with median follow-up of 121 months. There were no long-term survivors in the metachronous group; all were dead of disease within 21 months from initial presentation of original tumor. With these data we relate prognosis to extent of disease and discuss a general approach to the management of bilateral Wilms' tumor

    ABSTRACT Supernumerary tooth is a developmental anomaly and has been argued to arise from multiple etiologies. These teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. They can cause a variety of complications in the develo­ping dentition. Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anterior maxilla. Here is the presentation of a case of unusual location of supernumerary teeth located in between mandibular first and second molar region bilaterally.

    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...... 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...

  18. Corynebacterium pseudotuberculosis associated with otitis media-interna in goats

    Directory of Open Access Journals (Sweden)

    Rhoda Leask

    2013-08-01

    Full Text Available Corynebacterium pseudotuberculosis or caseous lymphadenitis is a common condition in sheep and goats. Two cases are described involving otitis media-interna and, in one case, cerebellar abscessation. The first case began with otitis externa and progressed to cerebellar abscessation, presumably as a result of C. pseudotuberculosis infection based on the macroscopic appearance of the abscess. The second case of otitis media-interna involved C. pseudotuberculosis with parasitic encephalitis or secondary meningo-encephalitis. Caseous lymphadenitis is a worldwide problem in livestock and also has zoonotic implications. Antimicrobial therapy of abscesses is often unrewarding due to the thick encapsulation of the abscesses and the extremely contagious nature of the organism. Alternative measures of treating this condition must be sought. In flocks or herds where caseous lymphadenitis has been diagnosed, it should be considered as a differential diagnosis for neurological conditions. The potential for spread must be kept in mind when it is suspected to be the cause of otitis in livestock.

    Full Text Available Resumen Este texto constituye una propuesta teórica sobre la dimensión expresiva del habla interna. Se describe el fenómeno de interés enfatizando la propuesta de Karl Bühler respecto a la expresividad del lenguaje, los estudios de Heinz Werner sobre una dimensión fisionómica-organísmica del lenguaje humano y la aproximación teórico-empírico de Lev Vygotsky respecto al fenómeno del habla interior en la experiencia humana. Se concluye que en algunos pasajes de la obra de Vygotsky están las claves para una comprensión del habla interna expresiva, específicamente en la influencia de la esfera afectivo-volitiva en el desarrollo del pensamiento y de la palabra. Finalmente, se propone una integración de la concepción monológica vygotskyana del lenguaje interior, la noción werneriana del lenguaje fisionómico-organísmico y la propuesta bühleriana de la dimensión expresiva del lenguaje humano, para una comprensión integradora de la expresividad del lenguaje interior.

    Deep brain stimulation (DBS) of either the globus pallidus interna (GPi) or subthalamic nucleus (STN) is similarly effective for treating somatomotor manifestations of Parkinson's disease (PD), but differences in how stimulation of each target affects oculomotor function are poorly understood. We sought to determine if stimulation of the STN, but not the GPi, affects oculomotor function in PD patients. Nineteen PD patients with DBS implants (8 bilateral GPi, 9 bilateral STN and 2 unilateral STN) were studied. Testing was performed with stimulation on, then off. Somatomotor function was tested using the Unified Parkinson's Disease Rating Scale (UPDRS) motor exam. For oculomotor testing, patients performed pro- and antisaccade tasks while monitored with an infrared eye tracker. Saccadic latency, saccadic intrusions, and square-wave jerks (SWJs) were measured for each trial. As expected, UPDRS motor scores improved with both GPi and STN stimulation. With GPi stimulation, there was no significant difference in oculomotor function with stimulation on or off. However, with STN stimulation on, there was a significant increase in the mean number of SWJs/s, as well as a significant decrease in latency for both pro- and antisaccade tasks. Stimulation of either GPi or STN had similar effects on somatomotor function, but only STN stimulation significantly altered oculomotor function. Copyright © 2013 S. Karger AG, Basel.

    Perminder S Sachdev

    Full Text Available BACKGROUND: We have previously reported the results of Deep Brain Stimulation (DBS of the antero-medial globus pallidus interna (GPi for severe Tourette Syndrome (TS in 11 patients. We extend this case series to 17 patients and a longer follow-up to a maximum of 46 months. METHODS: 17 patients (14 male; mean age 29.1 years, range 17-51 years with severe and medically intractable TS were implanted with Medtronic quadripolar electrodes bilaterally in the antero-medial GPi. The primary outcome measure was the Yale Global Tic Severity Scale (YGTSS. Secondary outcome measures included the Yale-Brown Obsessive Compulsive Scale, Hamilton Depression Rating Scale, Gilles de la Tourette Quality of Life Scale and Global Assessment of Functioning. Follow up was at one month, three months and finally at a mean 24.1 months (range 8-46 months following surgery. RESULTS: Overall, there was a 48.3% reduction in motor tics and a 41.3% reduction in phonic tics at one month, and this improvement was maintained at final follow-up. 12 out of 17 (70.6% patients had a>50% reduction in YGTSS score at final follow up. Only 8 patients required ongoing pharmacotherapy for tics post-surgery. Patients improved significantly on all secondary measures. Adverse consequences included lead breakage in 4 patients, infection (1, transient anxiety (2, dizziness (1, poor balance (1 and worsening of stuttering (1. CONCLUSIONS: This case series provides further support that antero-medial GPi DBS is an effective and well tolerated treatment for a subgroup of severe TS, with benefits sustained up to 4 years.

  4. Bilateral spontaneous carotid artery dissection.

    Townend, Bradley Scott; Traves, Laura; Crimmins, Denis

    2005-06-01

    Bilateral internal carotid artery dissections have been reported, but spontaneous bilateral dissections are rare. Internal carotid artery dissection can present with a spectrum of symptoms ranging from headache to completed stroke. Two cases of spontaneous bilateral carotid artery dissection are presented, one with headache and minimal symptoms and the other with a stroke syndrome. No cause could be found in either case, making the dissections completely spontaneous. Bilateral internal carotid artery dissection (ICAD) should be considered in young patients with unexplained head and neck pain with or without focal neurological symptoms and signs. The increasing availability of imaging would sustain the higher index of suspicion.

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.

    Full Text Available In this study we present find of skeletal remains from the St. Martin Cathedral from the 17th – 18th centuries which were excavated in year 2008. Especially of individual from grave no. 2/2008 – preserved cranium showed marks of endocranial hyperostosis (stage B according Hershkovitz et al. 1999. Hyperostosis frontalis interna (HFI is an overgrowth of bony tissue on the inner plate of the frontal bone of the calvaria, the irregular thickening of the endocranium (may be 1 cm or thicker. It is typically bilateral and symmetrical, and may extend to involve the parietal bones. It was first described in 1765 by Morgagni and Santorini as an obesity and virilism associated with thickening of internal table of the frontal bone called hyperostosis frontalis interna. HFI appears more commonly in women than in men, with an estimated male:female ratio 1:9, usually in age 35 years and older women. In modern population this condition is most prevalent in postmenopausal females, with frequencies of 40 – 62% reported, in general population, composed of males and females of different ages HFI affects 3 – 15% of individuals. In contrast, HFI is rarely reported in an archeological context. Using an anthropomorphological and paleopathological examination of the skeletal remains we realized that this women was in age category adultus II (30 – 39 years or older, her stature was cca 151.875 cm and she also suffered from DISH, healed fracture of styloid process of right ulna, osteoarthrosis of humeral and femoral heads and spondylosis.

Julga que, além de proteger a parede vascular arterial nas hipertensões arteriais súbitas, possa contribuir no mecanismo de controle e regulação do fluxo sanguíneo carotídeo, por considerar diferentes as condições fisiológicas do seio cavernoso em relação aos demais seios venosos durais e o sistema venoso endocraniano; consequente de sua constituição cavernosa, diferente dos demais canais sanguíneos venosos, com fisiollogia venosa própria e funções diferentes. Procura assemelhá-los aos demais distritos do organismo em que existem plexos cavernosos nos quais a tensão venosa chega a grandes proporções, comparada às demais regiões em que não existe esta constituição morfológica. Estabelece a correlação resultante ao mecanismo de resistência cérebro-vascular do qual considera participar, diferindo dos demais seios durais conjugado artéria carotida-beio cavernoso e veias encefálicas. Ainda valoriza o sifão carotídeo fisiologicamente e julga que o mesmo participa da hemodinâmica quando o paciente se encontra caído (em plano horizontal com hipotensão arterial, favorecendo a chegada sanguínea ao cérebro, evitando a anóxia e descerebração consequente dentro de determinados limites, sendo mais um meio de defesa do organismo.

    Full Text Available Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

    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.

  9. Transcriptome profiling of the theca interna in transition from small to large antral ovarian follicles.

    Directory of Open Access Journals (Sweden)

    Nicholas Hatzirodos

    Full Text Available The theca interna layer of the ovarian follicle forms during the antral stage of follicle development and lies adjacent to and directly outside the follicular basal lamina. It supplies androgens and communicates with the granulosa cells and the oocyte by extracellular signaling. To better understand developmental changes in the theca interna, we undertook transcriptome profiling of the theca interna from small (3-5 mm, n = 10 and large (9-12 mm, n = 5 healthy antral bovine follicles, representing a calculated >7-fold increase in the amount of thecal tissue. Principal Component Analysis and hierarchical classification of the signal intensity plots for the arrays showed no clustering of the theca interna samples into groups depending on follicle size or subcategories of small follicles. From the over 23,000 probe sets analysed, only 76 were differentially expressed between large and small healthy follicles. Some of the differentially expressed genes were associated with processes such as myoblast differentiation, protein ubiquitination, nitric oxide and transforming growth factor β signaling. The most significant pathway affected from our analyses was found to be Wnt signaling, which was suppressed in large follicles via down-regulation of WNT2B and up-regulation of the inhibitor FRZB. These changes in the transcriptional profile could have been due to changes in cellular function or alternatively since the theca interna is composed of a number of different cell types it could have been due to any systematic change in the volume density of any particular cell type. However, our study suggests that the transcriptional profile of the theca interna is relatively stable during antral follicle development unlike that of granulosa cells observed previously. Thus both the cellular composition and cellular behavior of the theca interna and its contribution to follicular development appear to be relatively constant throughout the follicle growth

Essas falhas prejudicam o processo, atrasam o cronograma operacional de produção, geram altos custos de manutenção, além de gerar riscos à saúde e ao meio-ambiente. Devido ao fato de que a maioria dos equipamentos, tubulações e dutos das plataformas de produção são constituídos de aço (em geral, aço carbono, a indústria de exploração de petróleo estará sempre convivendo com os processos corrosivos. A utilização de um plano de monitoração da corrosão para diagnosticar, controlar e gerenciar a evolução dos processos corrosivos nas plataformas é a estratégia de ação proposta nesse trabalho. O Plano de Monitoração da Corrosão Interna (PMCI se baseia na análise laboratorial da corrosividade de fluídos e resíduos coletados periodicamente nos sistemas das plataformas de operação; na taxa de corrosão determinada pela utilização periódica de cupons instalados nas tubulações dos sistemas das plataformas, como cupons de perda de massa e sondas de resistência elétrica; e finalmente, na coleta periódica de dados operacionais obtidos durante a operação dos sistemas das plataformas. O PMCI irá direcionar e gerenciar as ações a serem tomadas no caso de um agravamento de um processo corrosivo, identificando dos mecanismos corrosivos e sua localização nos diversos sistemas das plataformas.

    Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases and patellar tendinopathy. The authors report a rare case of a 34-year-old man with simultaneous bilateral rupture of the patellar tendon caused by minor trauma. The patient is a retired basketball player with no past complaints of chronic knee pain and a history of steroid use. Surgical management consisted in primary end-to-end tendon repair protected temporarily with cerclage wiring, followed by a short immobilization period and intensive rehabilitation program. Five months after surgery, the patient was able to fully participate in sport activities.

    Full Text Available Simultaneous bilateral primary pneumothorax is a very rare (1.6 / 100,000 and life-threatening condition. Clinical presentation may vary from mild dyspnea to tension pneumothorax. It may be milder particularly in younger patients, but more severe in patients with advanced age, and tube thoracostomy is a life preserver in the latter group. Since mortality and recurrence rates following tube thoracostomy are high, endoscopic approaches to bilateral hemithorax have been reported in literature. Apical wedge resection and pleural procedures are recommended in video thoracoscopy or mini thoracotomy even if no bulla and/or bleb are detected. Bilateral surgical interventions and additional pleural procedures are associated with increased rate of post-operative complications and longer postoperative hospital-stays. As a first-line approach, the surgical method toward any side of lung with air leakage following a previous tube thoracostomy is considered less invasive, especially in younger patients. Here, we present a case of simultaneous bilateral primary spontaneous pneumothorax (SBPSP in a 21-year old male with no history of smoking and chronic pulmonary disease. A unilateral surgical intervention was performed, and no recurrence was observed during 5-year follow up.

  20. Transcriptome profiling of the theca interna from bovine ovarian follicles during atresia.

    Directory of Open Access Journals (Sweden)

    Nicholas Hatzirodos

    Full Text Available The theca interna is a specialized stromal layer that envelops each growing ovarian follicle. It contains capillaries, fibroblasts, immune cells and the steroidogenic cells that synthesize androgens for conversion to estradiol by the neighboring granulosa cells. During reproductive life only a small number of follicles will grow to a sufficient size to ovulate, whereas the majority of follicles will undergo regression/atresia and phagocytosis by macrophages. To identify genes which are differentially regulated in the theca interna during follicular atresia, we undertook transcriptome profiling of the theca interna from healthy (n = 10 and antral atretic (n = 5 bovine follicles at early antral stages (<5 mm. Principal Component Analyses and hierarchical classification of the signal intensity plots for the arrays showed primary clustering into two groups, healthy and atretic. A total of 543 probe sets were differentially expressed between the atretic and healthy theca interna. Further analyses of these genes by Ingenuity Pathway Analysis and Gene Ontology Enrichment Analysis Toolkit software found most of the genes being expressed were related to cytokines, hormones and receptors as well as the cell cycle and DNA replication. Cell cycle genes which encode components of the replicating chromosome complex and mitotic spindle were down-regulated in atretic theca interna, whereas stress response and inflammation-related genes such as TP53, IKBKB and TGFB1 were up-regulated. In addition to cell cycle regulators, upstream regulators that were predicted to be inhibited included Retinoblastoma 1, E2 transcription factor 1, and hepatocyte growth factor. Our study suggests that during antral atresia of small follicles in the theca interna, arrest of cell cycle and DNA replication occurs rather than up- regulation of apoptosis-associated genes as occurs in granulosa cells.

    2016-12-01

    Full Text Available Lymphoma involving the lacrimal gland is rare. Most of the cases are unilateral at presentation. In this case, we present the diagnostic evaluation of a patient with bilateral lacrimal gland lymphoma. At presentation, the patient had inferomedial eccentric proptosis of the right eye. The patient also had limitation in the upper and lateral gaze in this eye. On magnetic resonance imaging, a mass was detected not only in the right but also in the left eye corresponding to the area of the lacrimal gland. Excisional biopsy was performed in the right eye with lateral orbitotomy approach. Histopathological examination revealed extranodal marginal zone lymphoma involving the lacrimal gland. No concurrent systemic lymphoma was detected during systemic evaluation of the patient. The patient was directed to the oncology department for systemic treatment planning. In conclusion, bilateral involvement is rare in lacrimal gland diseases but it can show severe diseases like lymphoma.

    Focal hand dystonia in musicians, also known as musician's dystonia, is a task-specific movement disorder characterized by unwanted involuntary muscle contractions occurring only when playing a musical instrument. Case 1 was a 50-year-old female professional pianist who underwent staged bilateral ventro-oral (Vo) thalamotomy, with an interval between the first and second surgery of 4 years. The first surgery (right Vo thalamotomy) led to significant improvements in dystonic symptoms without any complications. Pre- and postoperative Tubiana's musician's dystonia scale (TMDS) scores were 2 and 5, respectively. The second surgery (left Vo thalamotomy) also led to significant improvements in dystonic symptoms, with dysarthria and verbal recall disturbance resolving within 3 months. Pre- and postoperative TMDS scores were 2 and 5, respectively. The patient was subsequently able to return to live-stage performances. Case 2 was a 48-year-old male clarinet repair technician who underwent staged bilateral Vo thalamotomy, with an interval between the first and second surgery of 13 months. The first surgery (right Vo thalamotomy) led to dramatic improvements in symptoms without any complications. Pre- and postoperative TMDS scores were 2 and 5, respectively. The second surgery (left Vo thalamotomy) also led to significant improvements in symptoms with transient hypophonia. Pre- and postoperative TMDS scores were 2 and 5, respectively. The patient was subsequently able to return to work without difficulty. The findings in these 2 cases indicate the utility of bilateral stereotactic Vo thalamotomy in the treatment of medically intractable musician's dystonia affecting both hands.

Es una enfermedad multifactorial, caracterizada por procesos inflamatorios y la internalización continua de moléculas lipídicas al interior del vaso. Los estudios de genes candidato han proporcionado conocimiento acerca de la fisiopatología de esta enfermedad y han permitido la postulación de algunos polimorfismos como responsables de la susceptibilidad genética en diversas poblaciones. En particular, estos polimorfismos que modulan ciertas vías moleculares tales como el estrés oxidativo, el metabolismo lipídico y la trombogénesis se asocian con el desarrollo de las enfermedades cardiovasculares. Se han conducido varios estudios para identificar nuevas variantes asociadas con la enfermedad que han permitido el descubrimiento de nuevas vías de la enfermedad. Aunque el hallazgo de nuevos genes asociados a la enfermedad cardiovascular a través de enfoques como el escaneo global del genoma ha contribuido al entendimiento del desarrollo de esta condición, el conocimiento aún es limitado y poco concluyente. El objetivo de esta revisión es identificar los genes y las variantes polimórficas asociadas a la enfermedad cardiovascular, de acuerdo con los diferentes enfoques de análisis de asociación genética.

    Concerning a hydraulic bilateral construction robot, its system constitution, structures and functions of important components, and the results of some tests are explained, and the researches conducted at Gifu University are described. The construction robot in this report is a servo controlled system of a version developed from the mini-shovel now available in the market. It is equipped, in addition to an electrohydraulic servo control system, with various sensors for detecting the robot attitude, vibration, and load state, and with a camera for visualizing the surrounding landscape. It is also provided with a bilateral joy stick which is a remote control actuator capable of working sensation feedback and with a rocking unit that creates robot movements of rolling, pitching, and heaving. The construction robot discussed here, with output increased and response faster thanks to the employment of a hydraulic driving system for the aim of building a robot system superior in performance to the conventional model designed primarily for heavy duty, proves after tests to be a highly sophisticated remotely controlled robot control system.

    2009-01-01

    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

    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.

    2008-01-01

    Full Text Available La persistencia de la vena cava superior izquierda asociada con cardiopatías congénitas suele ser un hallazgo benigno, sin repercusión hemodinámica ni quirúrgica. Sin embargo, en ocasiones su presencia puede constituir una entidad fisiopatológica que requiere tratamiento o conducir a modificaciones en las técnicas quirúrgicas utilizadas para otras malformaciones. Estas situaciones en las que la presencia de la vena cava superior izquierda requiere un abordaje quirúrgico específico son motivo de revisión en el presente trabajo. Asimismo, se comenta una técnica quirúrgica original utilizada en estos pacientes, y recientemente comunicada por nuestro grupo, en relación con cada una de las diferentes presentaciones anatómicas.

    Full Text Available Descartes afirma que el cogito se “experimenta en uno” (apud se experiatur o se “siente en uno mismo” (“il sent in lui-même”, pero también ha señalado que uno no siente sino a través del cuerpo. El problema es que, en las Meditaciones, el cogito fue caracterizado cuando todavía no se había demostrado la existencia del cuerpo. Pese a esto, Descartes parece haberse dejado influir por ciertas sen- saciones internas de duda y certeza. En el trabajo se sostiene que esto fue posible porque esas sensaciones internas son efecto de una ratio implícita: la existencia de un Dios no engañador.

    Full Text Available Atualmente, a comunicação empresarial é algo imprescindível no mundo dos negócios. Em busca de crescimento e melhores resultados, as empresas sempre investiram na comunicação destinada aos clientes, o público externo. Porém, há algum tempo, percebeu-se a necessidade de conquistar o público interno, basicamente composto por empregados e familiares, para que os bons resultados e qualidade de produtos e serviços sejam mantidos. As empresas passaram a investir em ações de comunicação interna e de endomarketing para estreitar relacionamento e motivar os empregados, com o objetivo de obter os resultados esperados. Muitos profissionais costumam, erroneamente, conceituar comunicação interna e endomarketing como sinônimos. Este artigo tem por objetivo diferenciá-los.

    Full Text Available Trata-se de um estudo de natureza descritiva cujo objetivo foi analisar a opinião da equipe de enfermagem em relação à internação conjunta da unidade pediátrica de um hospital público. A coleta de dados foi através de um formulário com questões abertas e fechadas. A população do estudo foi de 28 profissionais da equipe de enfermagem do sexo feminino, com predominância na faixa etária dos 31 aos 40 anos de idade. Na sua maioria, trabalhavam na unidade de 1 a 5 anos. Com relação à opinião dos funcionários sobre a internação conjunta 53% referiram significar uma recuperação rápida e 44% como direito da criança. As facilidades e as dificuldades da internação conjunta referida pelos profissionais sobre as crianças, foram que estas não se adaptam com o ambiente hospitalar e que os acompanhantes influenciam negativamente na execução dos procedimentos. Porém fornecem mais segurança para as crianças. A infra-estrutura e planta física não oferecem condições necessárias para a internação conjunta. Através dos resultados deste estudo demonstra-se à necessidade de educação continuada para os profissionais para a melhoria das relações humanas e interpessoais e também a elaboração de um protocolo para melhor orientação da rotina e normas da unidade pediátrica pela equipe de enfermagem.

    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.

    Four cases of bilateral internal carotid occlusion are reported with respect to clinical features, hemodynamics and various image diagnosis. MRI is applied to three cases. The patients comprised 2.08 % of all cerebral occlusive diseases treated during the past five years at our clinic. One case is of abrupt onset and three cases are progressing profiles. In one of these cases, collateral circulation is supplied mainly by leptomeningeal anastomosis of the posterior cerebral artery and posterior pericallosal artery branching from the basilar artery. In two of them, they are supplied through the circle of Willis. Middle cerebral artery occlusion, occlusion supra occlusionem, however, causes decisive ischemic lesion in its teritory. Applying MRI, complicated ischemic lesions, such as lacunar infarction, paraventricular lesion, deep white matter lesion and border zone infarction can clearly be identified. In the case of total aphasia, the lesions responsible are demonstrated clearly by MRI, but only vaguely by X-ray CT. (author)

    A 5-year-old castrated male domestic longhair cat was presented with neurological signs consistent with a central vestibular lesion and left Horner's syndrome. Computed tomography images revealed hyperattenuating, moderately contrast-enhancing material within the left tympanic bulla, most consistent with left otitis media/interna. Marked neutrophilic pleocytosis was identified on cerebrospinal fluid analysis. Streptococcus equi subspecies zooepidemicus (SEZ) was isolated from the cerebrospinal fluid. Intracranial extension of otitis media/interna is relatively infrequent in small animals. There are no reports of otitis media/interna caused by SEZ in dogs or cats. This is the first report of otitis media/interna and presumptive secondary meningoencephalitis caused by SEZ in a cat. Copyright © 2011 ISFM and AAFP. Published by Elsevier Ltd. All rights reserved.

    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

    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.

    The aim of the study was to investigate whether children with bilateral conductive hearing loss benefit from their second device (i.e., the bilateral bone conduction device [BCD]). Speech recognition in noise was assessed in 10 children fitted with bilateral BCDs during childhood. Speech recognition was measured in 2 conditions with both BCDs active. Spatial resolution was tested with the Minimum Audible Angle test in the bilateral and monaural listening conditions. Children demonstrated an improvement in speech recognition when speech was presented from the front and noise was presented from the right-hand side as compared with both speech and noise being presented from the front. The minimum audible angle decreased from 57° in the best monaural condition to 13° in the bilateral condition. The audiological outcomes demonstrate the advantage of bilateral BCD fitting in children with bilateral conductive hearing loss.

    Full Text Available Los bifosfonatos constituyen un grupo de fármacos inhibidores de la resorción ósea, utilizados en el tratamiento de numerosas patologías como la osteoporosis, la enfermedad de Paget, el mieloma múltiple, la hipercalcemia maligna y las metástasis óseas asociadas al cáncer de mama o de próstata. El principal efecto farmacológico de los bifosfonatos es la inhibición de la resorción ósea, mediante una disminución de la actividad de los osteoclastos, sin intervenir en la formación y mineralización del hueso. Son fármacos utilizados a nivel mundial con unos claros beneficios contrastados clínicamente. Numerosas publicaciones durante los últimos tres años, y debido a su utilización masiva, consideran que la osteonecrosis de los maxilares está asociada al tratamiento con bifosfonatos. Es importante que los pacientes sean informados del riesgo de presentarse esta complicación, para tener la oportunidad de someterse a procedimientos dentales previos al inicio del tratamiento. Las medidas preventivas deben realizarse antes, durante y después del tratamiento con bifosfonatos. El tratamiento quirúrgico debe reservarse para aquellos pacientes que presenten síntomas. Son necesarias nuevas investigaciones que clarifiquen esta complicación.Bisphosphonates constitute a group of inhibitors of bone resorption that are used for treating many disor-ders such as osteoporosis, Paget´s disease, multiple myeloma, malignant hypercalcemia and bone metas-tases associated with breast and prostate cancer. The main pharmacological effect of bisphosphonates is the inhibition of bone resorption, mediated by a decreased function of osteoclasts without interfering in bone formation and mineralization. These drugs are used worldwide, with clear and clinically proven benefits. Several publications within the last three years consider osteonecrosis of the jaw to be associated with bisphosphonate therapy as a result of their extensive use. It is important

    Full Text Available Introducción. La vigencia de las explicaciones cambia con las transiciones demográfica, epidemiológica y nutricional. Objetivo. Establecer la magnitud de inseguridad alimentaria y sus variables asociadas. Materiales y métodos. Se clasificaron 432 hogares mediante cinco métodos; se utilizaron las escalas de percepción de seguridad alimentaria (EPSA, la latinoamericana y caribeña (ELCSA, y otros tres:a según el consumo usual de energía del jefe del hogar, b según el consumo usual de energía de todos los miembros, y c según un algoritmo basado en el consumo y la condición de los menores. Mediante regresión binomial, se establecieron las variables asociadas a la inseguridad alimentaria. Resultados. La inseguridad varió entre 35,9 y 87 %. Según la ELCSA y b, los hogares con menores tienen menor riesgo de inseguridad 0,51 (IC95% 0,25-0,90 y 0,72 (IC95% 0,48-0,96. Según la EPSA y la ELCSA, no pagar los servicios públicos 1,75 (IC95% 1,23-2,28 y que el jefe del hogar declare que no accede a los alimentos 1,48 (IC95% 1,20-1,68, aumentan la inseguridad.

    Unilateral and bilateral sudden sensorineural hearing loss represent different disease entities. The unilateral condition is more common and predominantly idiopathic, and up to 65 per cent of patients spontaneously recover hearing. Conversely, the bilateral condition is rare, mostly associated with serious systemic conditions, and has a higher prevalence of morbidity and mortality. A literature search using the PubMed database was conducted using the MeSH terms 'sudden', 'bilateral' and 'sensorineural hearing loss'. One hundred and three reported cases of bilateral sudden sensorineural hearing loss were identified. The condition is most often associated with toxic, autoimmune, neoplastic and vascular conditions. A younger age of onset, with a bimodal age distribution, was seen for bilateral sudden sensorineural hearing loss, compared with the unilateral condition. Patients with the bilateral condition had more profound hearing loss, with poorer recovery and a 35 per cent mortality rate. Vestibular symptoms were also less common than in the unilateral condition. The presentation of bilateral sudden onset sensorineural hearing loss is a medical emergency requiring thorough and urgent investigation to exclude life-threatening and reversible conditions.

    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.

  9. Bilateral facial palsy associated with leptospirosis

    Directory of Open Access Journals (Sweden)

    Andressa Alves da Silva

    Full Text Available Leptospirosis is a zoonosis of worldwide occurrence caused by the spirochete Leptospira interrogans. It is an acute feverish disease with a broad clinical spectrum and follows a characteristic biphasic course. Bilateral facial palsy is a rare clinical condition and the differential diagnosis of its causes is extensive. The objective of this exploratory study, presented as a case report, is to describe the occurrence of bilateral facial palsy as an unusual manifestation of leptospirosis. This suggestion should not be overlooked when analyzing the causes for bilateral facial palsy, and should be considered with other possible differential diagnoses, some of which are potentially fatal.

    Full Text Available A hemipelvectomia interna é um procedimento cirúrgico adequado no tratamento de certos tumores de cintura pélvica. É uma alternativa terapêutica capaz de preservar o membro inferior do paciente, ao contrário das amputações clássicas como a amputação interilioabdominal (AIIA e desarticulação coxofemoral. De acordo com a classificação de Enneking, existem quatro tipos de hemipelvectomia interna, mas, se for necessário, é possível a associação de diferentes tipos de ressecção em um único procedimento. É fundamental que esta cirurgia seja indicada de forma correta para que interfira positivamente na morbimortalidade e qualidade de vida do paciente. Relatamos oito casos de hemipelvectomia interna em pacientes diagnosticados com tumores de cintura pélvica, bem como os tipos de tratamento neoadjuvantes e adjuvantes a que eles foram submetidos e o follow-up dos mesmos.Internal hemipelvectomy is a surgical procedure adequate for treatment of certain tumors of the pelvic girdle. Being a lower limb-preserving approach, it is a therapeutic alternative to the classical interilioabdominal amputation and hip joint disarticulation. According to Enneking`s classification, there are four types of internal hemipelvectomies, although the association of different types of resection in the same procedure is feasible if necesary. This surgical approach should be correctly indicated to positively affect the patient`s morbidity, mortality and quality of life. We report eight cases of internal hemipelvectomy in patients diagnosed with tumors of the pelvic girdle. We also discuss the neoadjuvant and adjuvant treatments used, along with their follow-up.

    Full Text Available Twenty-six species of ants associated with aphids, belonging to twelve genera, are collected. Three subfamilies are identified, being the Formicinae the more represented about number of samples, genera and species. On the other hand, Lasius niger has been the species that is found with a more number of aphids (fifty eight species, and it seems to be the ant with a more capacity to establish associations with the different species of aphids. 224 different associations between the ants and the aphids are established and 164 of them are not recorded in the bibliography consulted for Spain.

    Se han recogido veintiséis especies de hormigas asociadas a pulgones, pertenecientes a doce géneros. De las tres subfamilias identificadas, Formicinae ha sido la más representada en cuanto a número de muestras, géneros y especies. Lasius niger, por otra parte, ha sido la especie que se ha encontrado junto a un mayor número de pulgones (cincuenta y ocho especies, demostrando ser la hormiga con mayor capacidad para establecer asociaciones con las diferentes especies de pulgones. Se han establecido un total de 224 asociaciones diferentes entre las hormigas y los áfidos, de las cuales 164 no se han encontrado citadas en la bibliografía consultada para España.

    Full Text Available El virus del dengue es un virus ARN miembro de la familia Flaviviridae, la cual incluye, además, el de la fiebre amarilla, el del Nilo del Oeste y la encefalitis japonesa. Se realizó un estudio retrospectivo con tres pacientes diagnosticados de encefalitis asociada al dengue, en cuyas muestras de suero y líquido cefalorraquídeo se cuantificaron los niveles de las clases mayores de inmunoglobulinas por inmunodifusión radial y la manosa de unión a lectina, proteína de la vía de las lectinas del sistema del complemento por fluorometría. En el reibergrama se muestra la presencia de síntesis intratecal de las tres clases de inmunoglobulinas y ausencia de síntesis intratecal de lectina de unión a manosa. Existieron diferencias en cuanto al por ciento de síntesis intratecal de inmunoglobulinas, las cuales estuvieron relacionadas con el momento de la infección por el virus y la aparición de las manifestaciones neurológicas compatibles con una encefalitis. Este es el primer reporte de afectaciones neurológicas en pacientes cubanos con dengue. La respuesta inmune intratecal puede ser utilizada para el mejor conocimiento de la enfermedad y contribuir al desarrollo de posibles candidatos vacunales.

    2016-01-01

    Full Text Available En Venezuela, el 40% de los trabajadores está empleado en el sector informal. Este sector se caracteriza por baja productividad, lo que implica que el ingreso de los trabajadores que en él se emplean es inferior al que podrían obtener en empleos formales. Este trabajo utiliza datos de la Encuesta de Hogares por Muestreo (2012-2013 para estimar modelos de regresión lineal y por cuantil de diferencia en diferencias, utilizando algunas características demográficas como covariables. Se busca con ello cuantificar la pérdida asociada al trabajo en el sector informal, como una manera indirecta de estimar el tamaño del sector. Para satisfacer el supuesto de igual tendencia en los grupos se recurre a procesos de emparejamiento basados en el propensity score; este supuesto no se cumple para el cuantil superior de salarios. Los resultados sugieren que el trabajador del sector informal pierde, en promedio, cerca del 34% de su ingreso potencial, pérdida que es superior en las mujeres que en los hombres, pero sin un claro comportamiento con respecto al nivel educativo. El estudio indica que la diferencia promedio en los sueldos de ambos sectores tiende a reducirse.

  20. Estimadores de consistencia interna en las investigaciones en salud: el uso del coeficiente alfa

    Directory of Open Access Journals (Sweden)

    Franciele Cascaes da Silva

    Full Text Available La producción académica ha aumentado en el área de la salud, exigiendo cada vez más calidad en las publicaciones de gran impacto. Una de las formas de considerar la calidad es por medio de procedimientos que aumentan la consistencia del análisis de los datos, como la confiabilidad, que dependiendo del tipo de datos, puede ser evaluada por diferentes coeficientes, en especial el coeficiente alfa. Basados en lo anterior, la presente revisión reúne sistemáticamente artículos científicos producidos en los últimos cinco años, que de manera metodológica hicieron uso psicométrico del coeficiente α como un estimador de consistencia interna y de confiabilidad en procesos de construcción, adaptación y validación de instrumentos. La identificación de los estudios fue realizada sistemáticamente en las bases de datos Biomed Central Journals, Google Scholar, Web of Science, Wiley Online Library, Medline via Pubmed, Scielo, Scopus, Journals@Ovid, BMJ y Springer por medio del Portal de Periódicos CAPES, utilizando criterios de inclusión y exclusión. El análisis de los datos fue realizado por medio de triangulación, análisis de contenido y análisis descriptivo. Se obtuvo que la mayoría de los estudios fueron realizados principalmente en Irán (f=3, España (f=2 y Brasil (f=2, estos estudios tuvieron como objetivo testar las propiedades psicométricas de instrumentos, siendo que ocho estudios utilizaron el coeficiente α para evaluar la confiabilidad y nueve para evaluar la consistencia interna. Todos los estudios fueron clasificados como investigaciones metodológicas al analizar sus objetivos. Adicionalmente, cuatro estudios también fueron clasificados como correlacionales y uno como descriptivo-correlacional. Se puede concluir que a pesar de que el coeficiente α es ampliamente utilizado como uno de los principales parámetros para la evaluación de consistencia interna de instrumentos de medición del tipo cuestionario en el

Estudio de consistencia interna y reproducibilidad de tecnología diagnóstica. Ciento nueve sujetos entre 18 y 60 años respondieron en dos ocasiones a CAGE y a una encuesta sobre variables biol6gicas, sociodemográficas y de dieta. La consistencia interna de CAGE se evalu6 con el alfa de Cronbach y la reproducibilidad con el coeficiente de Spearman y el valor kappa de Cohen. Con regresión binomial obtuvimos medidas de asociación entre el riesgo de alcoholismo y las variables biológicas, sociodemográficas y de dieta. Resultados. El riesgo de alcoholismo para la población estudiada fue de 15,6% (IC, 9,0, 22,5. Los hombres presentaron un riesgo aumentado de alcoholismo tres veces mayor que las mujeres (p=0,02. El coeficiente alfa de Cronbach fue bajo para todas las preguntas de CAGE (mínimo, 0,08; máximo, 0,28. En la primera aplicación de CAGE se obtuvo un alfa de Cronbach de 0,20, y en la segunda, de 0,27 (p=0,226. El coeficiente de correlaci6n de Spearman fue de 0,65 (IC, 0,53, 0,75 para la población; de 0,58 (IC, 0,36, 0,73 para hombres, y de 0,80 (IC, 0,68, 0,88 para mujeres. Los valores de kappas alcanzados están entre moderados y buenos. Ninguna variable biológica, sociodemográfica o de dieta se asoció con el riesgo de alcoholismo. Conclusión. La baja consistencia interna de CAGE es debida a la multidimensionalidad de la prueba; dada su reproducibilidad y estabilidad de las medidas de asociación derivadas, es útil en la investigación epidemiológica en esta población.

    Full Text Available Bilateral tubal pregnancy is very rare and occurs in only 1 out of every 200,000 spontaneous pregnancies. In this case, a 29-year-old woman with a history of primary infertility underwent treatment with human menopausal gonadotropin (hMG-human chorionic gonadotropin (hCG, and became pregnant. A gestational sac (GS was not detected in the uterus and transvaginal ultrasonography (USG revealed GS with fetal heartbeat in the left adnexa at 7 weeks and 6 days of gestation. The patient underwent laparoscopic surgery and ultimately, bilateral tubal pregnancy was diagnosed. Consequently, bilateral fallopian tube resection was performed. Afterwards, she conceived by assisted reproductive technology (ART and delivered vaginally. This case suggests that even if a GS is found in one fallopian tube by USG, it is important to evaluate the other fallopian tube carefully.

  8. FLOWING BILATERAL FILTER: DEFINITION AND IMPLEMENTATIONS

    Directory of Open Access Journals (Sweden)

    Maxime Moreaud

    2015-06-01

    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.

    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.

    To present a case of a patient with simultaneous bilateral retinal detachments treated successfully with bilateral pneumatic retinopexy. Case report. This is a case of an otherwise healthy 49-year-old woman with no remarkable ocular history that presented with simultaneous phakic superior bilateral rhegmatogenous retinal detachments. Treatment on the day of presentation included laser retinopexy of the inferior lattice degeneration in the left eye and bilateral intravitreal injection of 0.4 cc of 100% C3F8 gas preceded by topical anesthesia. After 48 hours, both retinas were completely reattached, and bilateral laser retinopexy was performed to the superior tears. After a review of the literature, the authors could find only two reported cases of simultaneous bilateral retinal detachments treated successfully with pneumatic retinopexy. This is not only a cost-effective procedure but also allows treatment when there is no immediate operating room availability or a when a quick referral for surgery is not possible.

    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.

    Full Text Available Este trabajo tiene como propósito reflexionar sobre algunas circunstancias que, en Argentina, contribuyen a la crisis de la educación médica y al descontento tanto de pacientes como de profesionales. El centro de atención es la medicina interna. Del análisis surgen algunas paradojas vinculadas con la actual formación de grado y posgrado. Si bien el primer nivel de atención de la salud, en el marco de la atención primaria, puede resolver el 80% de los problemas de salud de la población, la enseñanza de la medicina interna continúa realizándose sobre el paciente hospitalizado. Esto afecta a la forma en que se practica la medicina, pues se privilegia la tecnología en el diagnóstico y tratamiento sobre la prevención de las enfermedades y la promoción de la salud. Las causas de este panorama son varias, destacando el poco tiempo dedicado a la educación en el ámbito del consultorio con pacientes ambulatorios.

    Full Text Available In bilateral thumb amputations, the functional impairment is serious and every attempt should be made to reconstruct the thumb. We report a case of bilateral post traumatic thumb amputation, reconstructed with bilateral second toe transfer. Only two such cases have been reported in literature so far. Though there are various modalities for the reconstruction of thumb, microvascular toe transfer has its own merits. The convalescent period is minimal with excellent function. It is bilaterally symmetric and aesthetically superior to the osteoplastic reconstruction. The technical details are discussed, and the long term functional and aesthetic results are presented.

En este trabajo se recoge buena parte del conocimiento existente sobre los mecanismos moleculares implicados en el establecimiento de la esteatosis hepática, el primer estadio de la enfermedad, y en su progreso a esteatohepatitis. Se ha prestado una atención especial al hígado graso asociado a la obesidad, clínica y experimental. En este caso, se valora la rata fa/fa, un modelo animal de obesidad con rasgos fenotípicos similares a los de la obesidad humana, incluyendo la resistencia a la insulina y la dislipemia. La esteatosis hepática se revela como una situación compleja, eminentemente metabólica, en la que se simultanean procesos metabólicos aparentemente contradictorios, así como estrés oxidativo, estrés de retículo endoplasmático, disfunción mitocondrial y descenso en la expresión de genes de supervivencia. En buena medida, en su base se sitúan señales extrahepáticas, como las producidas en una situación de resistencia periférica a la insulina asociada a un aumento de la masa adiposa y de ácidos grasos libres sistémicos, e internas, causantes de un desajuste de las funciones glucostática y lipidostática del hígado y de una mayor vulnerabilidad a otras agresiones.Non-alcoholic fatty liver disease is a chronic inflammation liver condition that is currently highly relevant because of its strong association with increasingly incident diseases such as obesity and type-2 diabetes mellitus.

    Full Text Available La biosíntesis de las hormonas esteroides es necesaria para mantener la función reproductiva y la homeostasis en general. Este proceso que se lleva a cabo en tejidos esteroidogénicos regulados en forma aguda o crónica, activa vías de señalización mediadas particularmente por cinasas de proteínas dependientes del adenosín monofosfato cíclico/AMPc (PKA. Datos obtenidos en placenta humana por nuestro grupo de trabajo y en otros tejidos informados en la literatura, muestran que la fosforilación dinámica de proteínas catalizada por PKA, está asociada a la esteroidogénesis, incluyendo su regulación hormonal. Sin embargo, se conoce la participación de otras cascadas de transducción de señales independientes de PKA y que son activadas por hormonas tróficas, citocinas o factores de crecimiento, así como por iones de cloruro y calcio e inclusive por metabolitos del ácido araquidónico. El estudio y comprensión de los factores estimulantes, así como de los mecanismos que regulan la síntesis de las hormonas esteroides, permitirá identificar los sitios potenciales de intervención y de esta manera coadyuvar al mantenimiento de la homeostasis y de las diferentes funciones dependientes de los mismos.

    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.

    To assess bilateral breast cancer patients, initially diagnosed with stage II unilateral breast cancer. 113 patients with stage 0-II breast cancer diagnosed between 1983 and 2011 were assessed. Of these, 8 patients had bilateral breast cancer: 7 patients with metachronous bilateral breast cancer and 1 patient with synchronous breast cancer. Breast ultrasound, mammography, computed tomography and magnetic resonance imaging were used to diagnose recurrence, loco regional and distant metastasis. Age at diagnosis ranged from 37 to 59 years, with a maximum age incidence in the 4th decade (age between: 31-40 years). The average time interval between the two breast cancers was 8.125 years. The most common histological type was invasive ductal carcinoma. All eight patients with bilateral breast cancer had at least one type of recurrence/metastasis, mostly in the liver, and statistically the pleuropulmonary and liver metastases were the most frequent causes of death. Patients in the 4th decade diagnosed with unilateral breast cancer are at risk of developing bilateral breast cancer. In metachronous breast cancer, the time interval between the detection of the second breast cancer and death is directly proportional to the time interval between the two breast cancers.

    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.

    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.

    Bilateral anterior dislocation of the shoulders with fractures of both greater tuberosities is very rare. A 76-year-old woman sustained a bilateral anterior dislocation of her shoulders with fractures of the greater tuberosity on both sides after a fall on stairs. Her arms were abducted and externally rotated. Radiological examination revealed the bilateral anterior dislocation and also the bilateral fractures of the greater tuberosity. Prompt closed reduction followed by a 3 weeks immobilization and subsequent rehabilitation allows a good outcome. Results at one-year follow-up were satisfactory with normal range of motion and no redislocations occurring. To our knowledge, this is the first reported case of bilateral anterior shoulder dislocation associated with fractures of both greater tuberosities in elderly woman.

    To present the results of bilateral superior rectus transposition with medial rectus recession in a case of chronic bilateral sixth nerve palsy. Bilateral superior rectus transposition with medial rectus recession resulted in full correction of esotropia with resolution of horizontal diplopia, improvement in abduction, and regain of stereoacuity in our case. There was minimal limitation of adduction, with no abnormal vertical or torsional changes. Bilateral superior rectus transposition with medial rectus recession appears to be a useful procedure for surgical treatment of bilateral sixth nerve palsy with minimal side effects. Given its potential for reduced risk of anterior segment ischemia (ASI), it may have especially good value in the select group of patients at risk for ASI. Studies with larger sample size and longer follow up are needed to further evaluate this procedure and elucidate the variables in surgical technique for superior rectus transposition.

    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.

    To describe the excellent outcome of surgery for bilateral giant retinal tears (GRTs) with better options of endotamponade. This is a case report of a 62-year-old man who presented with bilateral GRTs and associated retinal detachment. The tear in the right eye was supero-temporal and silicone oil was used as an endotamponade. The tear in the left eye was infero-temporal and perfluorocarbon liquid was used as an endotamponade. The outcome at 6 months after surgery was excellent with visual acuities of 6/6 in both eyes. Improved availability of endotamponade agents allows repair of bilateral GRTs to be done at the same time, with good surgical outcomes.

    To our knowledge, bilateral supernumerary kidney is a very rare renal abnormality and there are five cases presented in the literature. It is difficult to diagnose supernumerary kidney and clinicians have not detected most cases preoperatively. Laboratory and imaging studies were acquired and carefully examined. The normal laboratory tests were found. Emergency ultrasonography was performed and they revealed no signs of parenchymal abnormality in both kidneys. Serial imaging study including enhanced computed tomography (CT) was performed. An imaging study identified bilateral supernumerary kidney with expanded collecting systems. On each side, significant rotation anomaly was found. In addition, there were two different renal arteries originating from the aorta. This report presents radiological determinations of supernumerary kidney bilaterally in a young man. We think that CT commonly appears to be enough for the diagnosis of supernumerary kidneys

    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.

    Currently, no consistent evidence-based guidelines for the management of synchronous bilateral breast cancer (SBBC) exist and it is uncertain how presenting with SBBC affects patients' prognosis. We conducted a review of studies analyzing the association between SBBC and prognosis. The studies...... that reported adjusted effect measures were included in meta-analyses of effect of bilaterality on breast cancer mortality. From 57 initially identified records 17 studies from 11 different countries including 8,050 SBBC patients were included. The quality of the studies varied but was generally low with small...... sample sizes, and lack of consistent, detailed histo-pathological information. When doing meta-analysis on the subgroup of studies that provided adjusted effect estimates on breast cancer mortality (nine studies including 3,631 SBBC cases), we found that bilaterality in itself had a negative impact...

    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)

    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.

    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.

    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.

    Full Text Available OBJETIVO: Identificar variáveis associadas a internações sensíveis ao cuidado primário. MÉTODOS: Inquérito de morbidade hospitalar realizado com amostra aleatória de 660 pacientes internados em enfermarias de clínica médica e cirúrgica de hospitais conveniados com o Sistema Único de Saúde, em Montes Claros, MG, de 2007 a 2008. Foram realizadas entrevistas com os pacientes e seus familiares utilizando formulário próprio e pesquisa aos prontuários. A definição das condições consideradas sensíveis ao cuidado primário baseou-se na lista do Ministério da Saúde. A associação entre variáveis socioeconômicas e de saúde com as internações sensíveis foi analisada utilizando-se análises bivariadas e de regressão logística múltipla. RESULTADOS: O percentual de internações sensíveis ao cuidado primário no grupo estudado foi de 38,8% (n=256. As variáveis que se mantiveram estatisticamente associadas com as condições sensíveis ao cuidado primário foram: internação prévia (OR=1,62; IC 95%: 1,51;2,28, visitas regulares a unidades de saúde (OR=2,20; IC 95%: 1,44;3,36, baixa escolaridade (OR=1,50; IC 95%: 1,02;2,20, controle de saúde não realizado por equipe de saúde da família (OR=2,48; IC 95%: 1,64;3,74, internação solicitada por médicos que não atuam na equipe de saúde da família (OR=2,25; IC 95%: 1,03;4,94 e idade igual ou superior a 60 anos (OR=2,12; IC 95%: 1,45;3,09. CONCLUSÕES: As variáveis associadas às internações sensíveis são sobretudo próprias do paciente, como idade, escolaridade e internações prévias, mas o controle regular da saúde fora da Estratégia de Saúde da Família duplica a probabilidade de internação.RESUMEN OBJETIVO: Identificar variables asociadas a internaciones sensibles al cuidado primario.

    Full Text Available A passagem da modernidade para a pós-modernidade vem sendo intensamente estudada de uma perspectiva macro, ou social. São, no entanto, poucos os estudos que procuram compreender como está dando-se essa transição do ponto de vista micro, ou individual. Esse é o objetivo do presente trabalho. Uma análise do discurso de jovens entre 18 e 25 anos sobre o seu uso de telefones celulares deu visibilidade parcial a essa transição interna e permitiu identificar um processo de interpenetração de campos semânticos que dá concretude psicológica a algumas das principais características do mundo contemporâneo: seu imediatismo e sua fluidez.

    2011-01-01

    The purpose of this study was to investigate the ultrastructure of the membrana limitans interna (internal limiting membrane, ILM) and to evaluate alterations to the retinal cell layers after membrane peeling with vital dyes. Twenty-five patients (25 eyes) who underwent macular hole surgery were included, whereby 12 indocyanine green (ICG)- and 13 brilliant blue G (BBG)-stained ILM were analyzed using light, transmission electron and scanning electron microscopy. Retinal cell fragments on the ILM were identified in both groups using immunohistochemistry. Comparing ICG- and BBG-stained membranes, larger cellular fragments were observed at a higher frequency in the BBG group. Thereby, the findings indicate that ICG permits an enhanced separation of the ILM from the underlying retina with less mechanical destruction. A possible explanation might be seen in the known photosensitivity of ICG, which induces a stiffening and shrinkage of the ILM but also generates retinal toxic metabolites. Copyright © 2011 S.

    Luis Eusebio Alberto Avendaño González

    2014-10-01

    Full Text Available En la teoría jurídica actual el ámbito constitucional es la plataforma para la garantía de los derechos y las libertades; sin embargo, la Constitución mexicana prevé supuestos que son excluyentes entre sí. Esta circunstancia implica prescribir en el nivel constitucional un derecho y, a su vez, un no derecho, lo que por consecuencia crea un sincretismo metodológico. Este texto, además de denunciar tal contradicción, defiende la premisa de que la Constitución requiere de coherencia interna. Dicha idea toma como base el principio de igualdad y la interpretación judicial, para adecuar la coherencia teórica y normativa de la carta constitucional.

    Los estudios sobre las migraciones se han llevado a cabo principalmente en el contexto Norte-Sur, como si se tratara de un movimiento unidireccional, cuando la realidad muestra que estos flujos se producen también en el plano horizontal, es decir, dentro de las regiones del Sur, como se puede observar en el continente africano. Mediante este artículo se pretende hacer una reflexión sobre las migraciones internas e internacionales, en lo cual hacemos hincapié la entrada de extranjeros sea en forma regular e principalmente irregular cada vez más pronunciada en Mozambique. El procedimiento de recolección y procesamiento de datos fueron basados principalmente en la investigación bibliográfica, revisión de documentos y el análisis de los datos estadísticos disponibles sobre la migración en Mozambique. Los resultados de la investigación sugieren que la migración y la movilidad en Mozambique varían según la ubicación, perfil histórico, económico y ambiental de las regiones. Continúa la tendencia de la migración a los países vecinos, especialmente a Sudáfrica, al mismo tiempo que se observa la entrada de inmigrantes de diversas partes del mundo, provenientes en su mayoría de países africanos, que atraídos por la relativa estabilidad socioeconómica y política del país, buscan seguridad y mejores condiciones de vida.

El objetivo del estudio es estimar el coste de las DACD para el Sistema Nacional de Salud (SNS. Métodos: Se realizó un modelo económico para calcular el coste por episodio de DACD (por antibióticos, prolongación del ingreso hospitalario, procedimientos quirúrgicos, medidas de control de la infección, recurrencias de las infecciones tratadas y el coste anual de la DACD. El uso de recursos en la práctica clínica se obtuvo mediante un panel Delphi de clínicos españoles con experiencia en la DACD y los costes unitarios (€ 2012 de fuentes españolas. Resultados: Se estimó que anualmente se produjeron 7.601 episodios de DACD en España (incidencia de 17,1 episodios/año/10.000 altas hospitalarias con un gasto anual para el SNS de 32.157.093 €. Coste por episodio de DACD: 3.901 € (infección inicial, 4.875 € (primera recurrencia y 5.916 € (segunda recurrencia. Coste total de las recurrencias: 10.426.750 € anuales. El 95,6% del gasto se debería a la prolongación de la duración de la estancia hospitalaria, el 0,5% a tratamientos antibióticos, el 2,8% a intervenciones quirúrgicas y el 1,1% a las medidas de control de la infección. Los resultados del estudio fueron sensibles a la incidencia y tasa de letalidad de la DACD en España y a la duración de la prolongación de la duración de la estancia hospitalaria debida a la DACD. Conclusiones: Según este estudio, el gasto asociado a la DACD se debe fundamentalmente a la prolongación de los ingresos hospitalarios y tiene un gran impacto económico en el SNS.

    Full Text Available Paciente de 9 años, previamente sana, que ingresa en anasarca con síndrome nefrótico clínico y humoral, asociado a hipertensión arterial y microhematuria, con función renal normal y se comporta como corticorresistente. Se realiza 1° biopsia renal que informa glomerulonefritis proliferativa mesangial difusa con esclerosis focal y segmentaria. En tratamiento con ciclofosfamida y corticoides, presenta síndrome febril prolongado con anemia secundaria a crisis aplásica de la serie roja, asociada con una infección aguda por parvovirus B19, e insuficiencia renal aguda secundaria a nefritis tubulointersticial severa. La PCR para parvovirus B19 DNA fue positiva en tejido renal y médula ósea. La paciente evoluciona a insuficiencia renal crónica terminal. No se puede descartar que desde su inicio, el síndrome nefrótico estuviera asociado al daño glomerular por la infección viral, que comenzó como síndrome nefrótico con componentes nefríticos y que evoluciona inesperadamente a una nefritis tubulointersticial. Este sería el primer caso en el que se documenta como causa de insuficiencia renal crónica terminal, un daño tubulointersticial secundario a parvovirus B19.A previously healthy 9 year old girl developed nephrotic syndrome with hypertension, microhematuria and normal renal function. The patient evolved as steroid resistant nephrotic syndrome whose initial renal biopsy was consistent with diffuse proliferative mesangial glomerulonephritis with focal segmental glomerulosclerosis. At the time of cyclophosphamide and prednisone treatment, she developed a prolonged febrile syndrome. She also had severe anemia following an aplastic crisis induced by human parvovirus B19 infection and acute renal failure secondary to a severe tubulointersticial disease. Bone marrow and renal tissue, tested by polimerase chain reaction were positive for parvovirus, while the patient’s blood was negative. The renal involvement did not improve requiring

    Full Text Available Este trabajo busca determinar comparativamente diferencias y semejanzas de características específicas de la población migrante interna con 60 años y más de edad entre las divisiones administrativas mayores (DAM en Cuba y 14 países de América Latina. Se procesó información sobre migración interna de censos latinoamericanos de la década del 2000, proveniente de la página WEB del Centro Latinoamericano y Caribeño de Demografía (CELADE. Asimismo se presenta información relativa al envejecimiento de Cuba y los restantes países y se han calculado otros indicadores como porcentaje de migrantes y no migrantes, y también se estima un conjunto de indicadores expresivos de cierta propensión a migrar entre las DAM en los últimos 5 años previos al censo para la población de 60 y más años de edad. Se han empleado técnicas propias de la estadística, como tablas de contingencias, así como métodos de análisis estadístico de correspondencias simples y múltiples para explorar las relaciones existentes entre las categorías de las diferentes características demográficas de los migrantes en países seleccionados. Uno de los resultados muestra que en Cuba y el resto de la región aún no se observan signos de migración interna asociada a la salida de la actividad laboral, lo cual sucede a partir de los 60 años de edad en países desarrollados. Los análisis de correspondencia múltiple, permitieron conocer grupos afines de categorías de las variables estudiadas cuando estas se analizan simultáneamente. Así se encontró similitud entre Cuba y Chile por el valor de las variables de población con 60 años y más, esperanza de vida al nacer, tasa global de fecundidad e índice de envejecimiento. Las proporciones más elevadas de migrantes de “toda la vida” se observen en aquellos países que registran un mayor nivel relativo de desarrollo económico y social; Cuba, Argentina y en menor medida Chile, muestran los más altos

    Full Text Available OBJETIVO: Descrever a frequência de rastreadores de potenciais resultados adversos em internações no Sistema Único de Saúde. MÉTODOS: Estudo retrospectivo, incluindo as internações de adultos na clínica médica (n = 3.565.811 e clínica cirúrgica (n = 2.614.048 no Brasil em 2007. O Sistema de Informações Hospitalares foi utilizado como fonte de informação. A mensuração dos resultados adversos baseou-se no rastreamento de 11 condições clínicas, definidas em estudos internacionais anteriores, registradas no campo diagnóstico secundário. Foram realizadas análises bivariada e multivariada, no intuito de associar resultado adverso, óbito (variável dependente e outras variáveis como idade, utilização de unidade de terapia intensiva e realização de cirurgia. RESULTADOS: A frequência obtida foi 3,6 potenciais resultados adversos por 1.000 internações para ambas as clínicas, superior na clínica médica (5,3 por 1.000 em relação à clínica cirúrgica (1,3 por 1.000. Houve diferenças no perfil das internações: na clínica médica predominaram idosos, maior tempo médio de permanência, maior taxa de mortalidade e menor custo total de internação. O rastreador de resultado adverso mais frequente foi pneumonia hospitalar. Choque/parada cardíaca apresentou maior risco de óbito (OR = 5,76 em relação aos demais resultados adversos. Os maiores gastos com internações estiveram relacionados à sepse hospitalar. Os rastreadores de potencial resultado adverso apresentaram altas chances de óbito, mesmo com a introdução de variáveis como uso de terapia intensiva e realização de cirurgia. CONCLUSÕES: A alta frequência de resultados adversos em internações indica a necessidade de desenvolver estratégias de monitoramento e melhorias dirigidas para a segurança do paciente.

    Full Text Available A fibrose cística, também conhecida como mucoviscidose, é um distúrbio monogenético que se apresenta como uma doença multissistêmica. A incidência é de aproximadamente 1:2500 nascidos vivos. O mecanismo fisiopatológico é uma mudança qualitativa em todas as secreções exócrinas do organismo. O aumento da viscosidade dessas secreções leva à estase e obstrução mecânica, prejudicando a função secretora dos órgãos-alvo. O nariz e seios paranasais são freqüentemente envolvidos devido ao clearence mucociliar anormal, responsável pelo desenvolvimento de rinossinusite crônica, polipose nasal e pseudomucocele sinusal. OBJETIVO: É apresentar um caso raro de pseudomucocele bilateral em uma criança portadora de fibrose cística. DESCRIÇÃO DO CASO: M.F.B.R., 2 anos, masculino, apresentava obstrução nasal crônica e infecções pulmonares recorrentes. O exame clínico detectava presença de secreção nasal abundante, com descarga posterior em orofaringe. A tomografia computadorizada dos seios paranasais mostrou imagem sugestiva de pseudomucocele, com velamento dos seios maxilares e etmóides. A dosagem de sódio e cloro no suor apresentou alterações significativas. Optamos por tratamento cirúrgico, após internação do paciente para controle das manifestações pulmonares exacerbadas. A criança evoluiu com melhora do quadro obstrutivo nasal. CONCLUSÕES: A pseudomucocele é uma entidade que começou a fazer partes da rotina de diagnóstico diferencial a partir do momento em que os exames tomográficos tornaram-se parte da semiologia das doenças sinusais. Os pacientes com psedomucocele têm apresentado um aumento importante da sobrevida graças aos tratamentos atuais.Cystic fibrosis, also known as mucoviscidosis, is a monogenetic disorder that is presented as a multisystemic disease.

    A case of bilateral fibrotic contracture of the infraspinatus muscles in a five-year-old Belgian Shepherd dog is described. The dog was presented with progressive forelimb lameness with postural and gait abnormalities three months after an episode of overexertion. When walking, the lower part of both forelimbs swung in a lateral arc causing a circumduction movement and in the standing position, the dog showed elbow adduction with external rotation of the distal part of both front limbs. Orthopaedic examination revealed bilateral atrophy of both infraspinatus and supraspinatus muscles and restriction in the range of motion of both shoulders, especially when attempting abduction and flexion. No specific findings were observed in the shoulder or elbow radiographs but hyperechogenic areas were evident in the ultrasonographic examination of both infraspinatus muscles. A diagnosis of fibrotic contracture of both infraspinatus muscles was established and bilateral tenectomy of the insertion tendons of the infraspinatus muscles was performed. Complete recovery of the animal was achieved after the surgery, which was confirmed in a long-term follow-up (10 months). In conclusion, physical examination and ultrasonography allowed a proper diagnosis of the condition, and tenectomy of the infraspinatus muscles resulted in a complete recovery of the patient even with bilateral involvement.

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.

    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.

    The authors report a unique case of glioblastoma which caused permanent amnesia. Magnetic resonance imaging showed the lesion to be limited to the hippocampal formation bilaterally. Although glioblastoma extends frequently into fiber pathways and expands into the opposite cerebral hemisphere, making a 'butterfly' lesion, it is unusual for it to invade the limbic system selectively to this extent.

    Eighteen infantile cases with bilateral vocal cord paralysis were treated at our hospital from 1970 to 1993. All cases were diagnosed using a flexible fiberscope to examine the larynx. Direct laryngoscopy was performed under general anesthesia for the definite diagnosis and differential diagnosis from laryngomalacia, subglottic stenosis, tracheal stenosis, or laryngeal web. Bilateral vocal cord paralysis in children is a rare disease, there have been few and reported cases. Eight cases were male and 10 cases were female. Thirteen cases were congenital, 4 cases acquired and 1 case was unknown. The characteristic symptoms of bilateral vocal cord paralysis include normal or near normal phonation with inspiratory stridor which may progress to complete respiratory obstruction. Associated anomalies and diseases included 3 cases of immature infant, 2 of myelomeningocele, and single cases of Arnold-Chiari malformation, cerebral palsy, hydrocephalus, laryngomalacia, William's syndrome, Wiedemann-Beckwith syndrome, hypoxia, esophageal hiatus hernia, gastroesophageal reflex, spina bifida, COFS syndrome, and cerebral atrophy. Laryngeal function was completely recovered in seven cases following growth of the children incompletely recovered in five cases, and 2 cases retained right vocal cord paralysis. Tracheostomy was performed in 2 cases. One case died from the original disease, and the other one case was unknown. Swallowing function, phonation and development were good. Our experience suggests that the airway with bilateral vocal cord paralysis in children can be managed well without the need for tracheostomy.

    1996-01-01

    Purpose: To assess outcome of patients with bilateral breast carcinoma treated with bilateral breast conserving surgery with radiation therapy (CS+RT) and to compare their outcome to (1) patients with unilateral disease treated with CS+RT and (2) patients of comparable stage treated with bilateral mastectomy. Methods and Materials: The charts of all patients with the diagnosis of breast cancer treated with CS+RT at our facilities prior to 1993 were reviewed to identify patients with bilateral disease. A total of 50 patients identified as having bilateral breast cancer conservatively treated(BCT) served as the index population. Out of the 50 patients, 23 presented with synchronous bilateral breast cancer and 27 presented with metachronous bilateral breast cancer. A group of 984 patients with unilateral breast cancer (UCT) treated with CS+RT during the same time interval served as the first control group. A second control group was comprised of 42 patients with early stage bilateral breast cancer presenting during the same time interval treated with bilateral mastectomy (BMAST). Patients who had locally advanced disease in either breast or those patients treated exclusively for lobular carcinoma in situ in either breast were excluded from the analysis. Of the 42 BMAST patients, 33 presented with synchronous disease and nine presented with metachronous disease. Local-regional relapse rates were calculated from the date of treatment of each breast. Overall survival and distant relapse rates were calculated from the date of treatment of the second breast cancer diagnosed. Survival curves were calculated via the life table method and statistical comparisons between curves were performed using the log rank statistic. Chi square analysis was used to detect differences between categorical variables. Results: As of December 1995, the median follow-up of the bilateral conservatively treated patient population was 9.4 years. No statistically significant differences were noted

    Full Text Available History of present illness: A 24-year-old male was brought in by paramedics status post motor vehicle collision (MVC into an electric pole and tree at high speed. The patient was an unrestrained driver who required extrication. The patient complained of left hip pain, left foot pain, and difficulty extending his bilateral lower extremities. He denied numbness or tingling to his lower extremities. The patient had normal vitals; his bilateral lower extremities were held in flexion at the hips, but otherwise had no obvious injuries. The patient’s pelvis was stable with palpable distal pulses and intact motor and sensory function of his distal lower extremities. 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

    Objective To investigate the mortality associated with cardiovascular diseases and the effect of estrogen treatment in women who underwent unilateral or bilateral oophorectomy before menopause. Design We conducted a cohort study with long-term follow-up of women in Olmsted County, MN, who underwent either unilateral or bilateral oophorectomy before the onset of menopause from 1950 through 1987. Each member of the oophorectomy cohort was matched by age to a referent woman from the same population who had not undergone any oophorectomy. We studied the mortality associated with cardiovascular disease in a total of 1,274 women with unilateral oophorectomy, 1,091 women with bilateral oophorectomy, and 2,383 referent women. Results Women who underwent unilateral oophorectomy experienced a reduced mortality associated with cardiovascular disease compared with referent women (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.67–0.99; P = 0.04). By contrast, women who underwent bilateral oophorectomy before age 45 years experienced an increased mortality associated with cardiovascular disease compared with referent women (HR, 1.44; 95% CI, 1.01–2.05; P = 0.04). Within this age stratum, the HR for mortality was significantly elevated in women who were not treated with estrogen through age 45 years or longer (HR, 1.84; 95% CI, 1.27–2.68; P = 0.001) but not in women treated (HR, 0.65; 95% CI, 0.30–1.41; P = 0.28; test of interaction, P = 0.01). Mortality was further increased after excluding deaths associated with cerebrovascular causes. Conclusions Bilateral oophorectomy performed before age 45 years is associated with increased cardiovascular mortality, especially with cardiac mortality. However, estrogen treatment may reduce this risk. PMID:19034050

    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.

    Conclusion and importance: Bilateral superior rectus transposition with medial rectus recession appears to be a useful procedure for surgical treatment of bilateral sixth nerve palsy with minimal side effects. Given its potential for reduced risk of anterior segment ischemia (ASI, it may have especially good value in the select group of patients at risk for ASI. Studies with larger sample size and longer follow up are needed to further evaluate this procedure and elucidate the variables in surgical technique for superior rectus transposition.

  7. Hardware Implementation of a Bilateral Subtraction Filter

    2009-01-01

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

Con base en el estudio de las geoformas litorales, los procesos dinámicos asociadosy su evolución reciente, se evaluó la amenaza por inundación y erosión asociada al actual ascenso del nivel del mar, proyectado por IP(C (panel Intergubemamcntal de Expertos de Cambio Climático en un metro pata el año 2100. A partir de la interpretación de imágenes de satélite y fotografias aéreas, apoyada en información secundaria y verificación de campo, se identificaron 15 unidades geomorfológicas básicas de origen estructural, fluvial y marino. Con base las características geomorfológicas y criterios de resiliencia frente a la acción del oleaje y la inundación litoral, se generó un modelo morfodinámico que pronostica el impacto del ascenso del nivel marino para el litoral Caribe colombiano. De acuerdo con este análisis, se estima que las unidades geomorfológicas recientes desarrolladas durante los últimos 2.500 años podrían ser reactivadas por el actual ascenso del nivel del mar, afectando numerosos centros urbanos tales como Cartagena, Santa Marta, Puerto Colombia y Turbo y actividades económicas de-importancia como el comercio portuario y el turismo. Para los 1.819 Km. de línea de costa del Caribe Colombiano, se estima que el 33.7% presenta alta susceptibilidad a la erosión marina, representado por geoformas que presentan grari fragilidad ante los procesos erosivos. En la linea de costa restante, 31,2% presenta susceptibilidad mec!ia y 35.1% susceptibilidad baja y muy baja, en una linea de costa caracterizada por geoformas con fragilidad y mecanismos de resiliencia variables.

    Full Text Available A injúria interna de impacto causa redução significativa da qualidade de frutos de tomate. O presente trabalho teve como objetivo avaliar a utilização do armazenamento sob atmosfera controlada na redução do desenvolvimento de uma desordem de amadurecimento conhecida como injúria interna de impacto. Tomates (Lycopersicon esculentum Mill, cv. Solimar, foram colhidos no estádio de amadurecimento verde-maduro e tratados com etileno, por 12 horas, a 20degreesC. Ao atingirem o estádio verde-rosado, sofreram uma queda de 40 cm de altura sobre uma superfície plana, lisa e maciça. Metade dos frutos foi então armazenada sobre atmosfera controlada (3% O2; 4% CO2; balanço com N2 por 8 dias a 20degreesC e 85-95% de umidade relativa, e então foram transferidos para atmosfera ambiente até completamente maduros. A outra metade dos frutos foi mantida continuamente em atmosfera ambiente à mesma temperatura e umidade relativa. Quando estavam completamente maduros, os frutos que sofreram injúria mecânica, armazenados sob atmosfera controlada e sob atmosfera ambiente, desenvolveram sintomas de injúria interna de impacto no tecido locular. O armazenamento sob atmosfera controlada não produziu efeitos significativos no conteúdo de vitamina C total e carotenóides totais para o pericarpo e o tecido locular injuriados. Entretanto, o tecido locular injuriado do tratamento armazenado sob atmosfera controlada possuía acidez titulável 15% superior (ao redor de 162 meq ácido cítrico. kg-1 do que o tratamento sob atmosfera ambiente (ao redor de 140 meq ácido cítrico. kg-1 e era similar ao tratamento não injuriado, armazenado em atmosfera ambiente (ao redor de 174 meq ácido cítrico. kg-1. O tecido pericárpico da região injuriada possuía atividade da poligalacturonase similar para os tratamentos armazenados sob ar ou sob atmosfera controlada. O extravasamento de eletrólitos do pericarpo injuriado foi similar para os tratamentos sob atmosfera

    El Río de la Plata (RdlP) presenta significativas variaciones naturales (hidrodinámicas y oceanográficas) asociadas a diferentes condiciones climáticas. El propósito de este trabajo es inferir los cambios de aportes continentales de sedimentos y su relación con las variaciones hidrológicas del Río de la Plata, a través del análisis de proxies sedimentológicos y geoquímicos en testigos de sedimentos de la plataforma interna uruguaya que registran los últimos 100 años, aproximadamente. A partir de la datación por 210Pb de dos testigos de sedimentos (GeoB 13813-4 y BAR1) se reconstruyó la geocronología del ambiente, y se relacionó con datos de las forzantes climáticas Pacific Decadal Oscillation, El Niño/La Niña Southern Oscillation, Atlantic Multidecadal Oscillation, y las anomalías hidrológicas de los ríos Paraná y Uruguay. Los valores más positivos y estables del Southern Oscillation Index, los cuales corresponden a fases La Niña, se observan en el periodo correspondiente entre 1910-1970, respecto al resto de la serie, donde se aprecia una mayor variabilidad y una tendencia hacia valores más negativos (eventos El Niño). Se hicieron dendrogramas (clustering) jerárquicos para ambos testigos. Para el testigo GeoB 13813-4, se utilizó la relación Ca/Ti y la granulometría, mientras que para BAR1 se recurrió a variables granulométricas y la tasa de sedimentación. El mayor aporte continental hacia la región de la plataforma adyacente al Río de la Plata registrado a partir del año 1970, podría ser el factor principal de los agrupamientos observados en los clusters para ambos testigos. Las agrupaciones mostraron una diferenciación en la década de 1970, lo que estaría asociado al aumento de los caudales de los ríos Paraná y Uruguay, durante las últimas tres décadas del siglo XX. Por otra parte se observa que la granulometría del testigo BAR1 presentó un mayor tamaño de grano y más variabilidad que en el caso del testigo Geo

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%. Además, todos los pacientes recibieron quimioterapia. CONCLUSIÓN: la terapia conservadora actual consistente en tratamiento local (termoterapia, crioterapia o braquiterapia y quimiorreducción permite preservar al menos un ojo y en algunos casos de los dos, muchas veces con buena agudeza visual, en niños con retinoblastoma bilateral; se evitan así la enucleación bilateral y la radioterapia externa usada en el tratamiento convencional con todos sus efectos secundarios.

De acuerdo con el artículo 139 la Constitución Política, este organismo público descentralizado del Ministerio de Justicia y Derechos Humanos tiene, como ente rector del sistema penitenciario nacional, la responsabilidad de hacer que los internos ocupen establecimientos adecuados (inciso 21 y que alcancen la reeducación, rehabilitación y reincorporación a la sociedad (inciso 22. Ambas responsabilidades, sin embargo, son claramente incumplidas. Las cárceles padecen hoy de sobrepoblación y hacinamiento sorprendentes, y es más, de condiciones adecuadas para impulsar seriamente el complejo proceso de reeducación, rehabilitación y reincorporación. Lo peor es que la sobrepoblación ya se hace incontrolable. El último año, de junio del 2011 a junio del 2012, la población de internos, según informe del INPE, llegó a 58 019, y alcanzó un asombroso crecimiento de 19,4%, es decir, 9 433 presos más. Las razones de todo este problema, sin duda, son tan diversas, que inclusive van más allá de las decisiones del propio organismo. Es conocido que esta situación es dramática en las cárceles de Lima y Callao, pero no deja de ser preocupante en el interior del país. Los autores - la mayoría - estando desempeñandonos en la Policía Nacional del Perú y siendo a la vez estudiantes de Derecho, quisimos conocer esta realidad en las cárceles en Huancayo, conformantes de la Oficina Regional Centro, y por está razón se comprometió en apoyar a las internas a través de un proceso de asesoría legal, previo estudio sobre la situación del Establecimiento Penitenciario de Mujeres de Concepción, una de la ocho cárceles de mujeres existentes en el país y la única en la zona centro.

  14. Responsabilidad social interna: entre la diferencia y el discurso en el escenario organizaciona

    Directory of Open Access Journals (Sweden)

    Nancy Piedad Diaz Ortiz

    Full Text Available El ensayo plantea que el discurso de la Responsabilidad Social Interna, como modelo de gestión, pretende homogenizar el tratamiento de los actores internos de la organización, una vez que es utilizado desde una perspectiva instrumental enfocada exclusivamente en temas legales de la relación laboral, en contraposición a una perspectiva sustantiva centrada en la humanización del ambiente laboral. En consecuencia, bajo este discurso, las organizaciones esconden prácticas que son, en verdad, des-humanizantes en la convivencia social y fomentan aún más la intolerancia hacia la diferencia. La discusión se contextualiza en Latinoamérica, en que cobran fuerza los discursos de la interculturalidad y de la defensa de los derechos humanos en las agendas políticas y empresariales, lo que resalta las contradicciones inherentes a estos discursos. A partir de una revisión bibliográfica sobre responsabilidad social, discurso, teoría de la identidad social y del autoconcepto, se discutieron los mecanismos individuales, sociales y organizacionales de elaboración y superación de estereotipos, que ayudan al individuo a establecer referencias para las percepciones e interpretación de la realidad. Se cuestiona que el discurso de la responsabilidad social interna podría proponer un cambio en la forma como se tratan los individuos en la organización. En este contexto, la diferencia no existiría como forma de exclusión social, más bien sería un medio para promover la equidad, valorando las particularidades de la acción individual en la organización, y no en el sentido de reforzar la diferencia entre el "nosotros" y "ellos" en función del rol que se ejerce en la dinámica organizacional.

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions

    Introduction Isolated traumatic fractures of both Patellae, occurring at the same time, in an otherwise healthy person, are very rare. The Patella, as a subcutaneous and a cancellous bone, is vulnerable to injury. However, simultaneous injury to both Patellae without the involvement of any other bony injuries occurs infrequently, and only a few cases have been reported in the literature. Case Presentation We report a rare case of isolated, traumatic bilateral Patella fracture with unusual fracture patterns and briefly review the literature. Conclusions In simultaneous bilateral Patella fractures, good functional outcome can be expected following a stable surgical fixation and a structured rehabilitation regime. However, personality of the fracture determines salvage versus sacrifice of the Patella. PMID:27218047

    Bilateral masseter muscle hypertrophy is an alteration in shape and thickness of the masseter muscles that can modify the width of the lower face causing aesthetic and functional problems. A 21-year-old man was referred to the Department of Maxillofacial Surgery at the Civil Hospital in Brescia by his dentist for an evaluation of his facial appearance with a square-face type. To reduce the undesirable facial appearance, a surgical intraoral approach was performed; the procedure includes the bilateral dissection of the masseter muscle, partial lipectomy, and the ostectomy of the mandibular angle assisted by a surgical guide built on a stereolithographic model. The patient was satisfied with the functional and aesthetic outcomes of both the profile and the frontal views. There was no evidence of complication at a 1-year follow-up. This new method yields optimal aesthetic results with an enhanced outline of the lower face.

    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.

    Full Text Available Elastofibroma dorsi is a rare, slow-growing soſt tissue tumor of the chest wall. The tumor typically located under the lower pole of the scapula. A 57-year-old woman who had retiredas a teacher, presented with a 1-year history of pain on the back and with a 3-month history of swelling located under the leſt scapula. Computed tomography and magnetic resonance imaging showed bilateral, solid soſt tissue tumors under the scapula. She underwent total resection of the tumor on the leſt side. Tumor was diagnosed histopathologically as elastofibroma. Elastofibroma dorsi can be undetermined because of its localization. Radiological examination is important especially on diagnosis of bilateral localization.

    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.

    2013-01-01

    Full Text Available Breast masses have a variety of benign and malignant etiologies. We present the case of a 28-year-old woman with bilateral large painful breast masses that developed rapidly in the three weeks before first presentation. Further investigation revealed bilateral ovarian masses. Biopsies of both ovarian masses were taken, and the pathology reported Burkitt’s lymphoma. Additional staging with a PET scan was suggestive of bone marrow involvement, but bone marrow biopsy was negative. Examination of the cerebrospinal fluid did not identify malignant cells. The patient underwent CODOX-M/IVAC chemotherapy, and a complete response was demonstrated after one cycle of treatment. Six months after finishing chemotherapy the patient remained in complete remission. To our knowledge this is the first case reporting simultaneous involvement of breast, ovaries, and bones in Burkitt’s lymphoma. Gynecologists and oncologists should be aware of this pattern. Polychemotherapy treatment must be initiated rapidly with curative intent.

    Sudden bilateral hearing loss are seen rarely and the toxic substance exposure constitutes a small part of etiology. A Fifty-eight-year-old woman admitted to our clinic with sudden bilateral hearing loss shortly after chlorpyrifos-ethyl exposure. Otolaryngologic examination findings were normal. The patient had 40 dB sensorineural hearing loss (SNHL) on the right ear and 48 dB SNHL on the left ear. Additional diagnostic tests were normal. The conventional treatment for sudden hearing loss was performed. On the second week following organophosphate (OP) exposure the patient's hearing loss almost completely resolved. OP's are heavily used in agriculture and should be taken into consideration as an etiologic factor in sudden hearing loss.

    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.

    Fibroadenomas are benign lesions of breast commonly found in young age group. These focal tumours contain both mesenchymal and glandular tissue. Giant juvenile fibroma of breast is rare variant of fibroadenoma found usually in less than 20 years of age. They present with rapid enlargement of single or multiple, discrete, painless large nodule of breast. A 14-years-old premenarche girl presented with large bilateral breast lumps for two months. FNAC showed features of juvenile fibroadenoma. Breast conserving surgical excision of lumps was performed and histopathology confirmed the diagnosis of juvenile fibroadenoma. Giant juvenile fibroadenomas are characterised by rapid enlargement of encapsulated mass. The aetiology is unknown, although end-organ hypersensitivity to normal level of estrogen is postulated. We present a case of bilateral giant juvenile fibroadenoma for its rarity.

    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

    The authors treated a case of bilateral accessory axillary breast tissue. Excision with histologic examination confirmed the diagnosis of fibroadenoma. Treatment left the woman with incision scars (3.5 cm) in the axillary pyramid, a location often not seen during a patient's normal movements. Thus, despite a minor aesthetic incision, gives the advantage of complete histologic analysis was gained. Liposuction treatment was used in this case. The scar results were good.

    We studied a 70-year-old woman with a unique combination of hyperkinesia and mutism. These findings differed from akinetic mutism because there was continuous bilateral ballism and dystonia--hence the term "hyperkinetic mutism." CT demonstrated bilateral calcifications in the basal ganglia, and MRI indicated bilateral watershed infarcts. Different dopaminergic mechanisms may underlie the hyperkinesia and mutism.

    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.

  20. High Performance, Three-Dimensional Bilateral Filtering

    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.

    The majority of plantar heel pain is diagnosed as plantar fasciitis or heel spur syndrome. When history or physical findings are unusual or when routine treatment proves ineffective, one should consider an atypical cause of heel pain. Stress fractures of the calcaneus are a frequently unrecognized source of heel pain. In a normal populatıon, the possibility of calcaneal stress fractures must be borne in mind with patients who have bilateral heel pain. When a stress fracture is considered, clinicans have different imaging options. First of all, x-rays must be used to evaluate for any visible osseous pathology. If plain films are inconclusive, the clinician can proceed with a bone scan or Magnetic Resonance Imaging. In the literature, calcaneal stress fractures are mostly reported in soldiers or athletes, but our case is one of a 44-year-old housewife with bilateral heel pain treated as Achilles tendinitis and plantar faciitis for a long time. Her final diagnosis was bilateral calcaneal fracture by Magnetic Resonance Imaging.

    A rare case of spontaneous bilateral rupture of the kidneys, occurring consecutively over a one-year period in a young male patient with 'hale' kidneys until then, is described. The patient's past history and thorough examination performed do not justify to assign the case under the heading of some of the etiological factors as the underlying cause of spontaneous kidney rupture. The literature survey on spontaneous bilateral non-tumor ruptures of kidneys shows that over a 20-year period, only 3 cases of bilateral spontaneous ruptures have been reported. It is pointed out that panarteritis nodosa followed by hemorrhagic fever with renal syndrome is the commonest underlying cause of such ruptures. Clinically spontaneous ruptures become manifest with emergency condition presenting severe renal colic, impaired to serious general condition, often with acute abdomen and hemodynamic breakdown, and no past history evidence of renal disease or injury. In the initial phase diagnosing is not always easy; it is usually made on the ground of physical examination and the full range of imaging studies used in urological practice and during operative treatment. Emphasis is laid on the fact that the imaging methods are not invariably sufficient to identify the exact etiological factor giving rise to such a severe condition, but nevertheless these methods have an essential practical bearing on diagnosing a rupture.

    Over 300 cases of femoral neck fractures following radiotherapy for intrapelvic malignant tumor have been reported in various countries since Baensch reported this disease in 1927. In Japan, 40 cases or so have been reported, and cases of bilateral femoral neck fractures have not reached to ten cases. The authors experienced a case of 75 year-old female who received radiotherapy for cancer of the uterus, and suffered from right femoral neck fracture 3 months after and left femoral neck fracture one year and half after. As clinical symptoms, she had not previous history of trauma in bilateral femurs, but she complained of a pain in a hip joint and of gait disturbance. The pain in left femoral neck continued for about one month before fracture was recognized with roentgenogram. As histopathological findings, increase of fat marrow, decrease of bone trabeculae, and its marked degeneration were recognized. Proliferation of some blood vessels was found out, but thickness of the internal membrane and thrombogenesis were not recognized. Treatment should be performed according to degree of displacement of fractures. In this case, artificial joint replacement surgery was performed to the side of fracture of this time, because this case was bilateral femoral neck fractures and the patient had received artificial head replacement surgery in the other side of fracture formerly.

    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.

    Full Text Available Introducción El éxito a largo plazo de un reemplazo total de rodilla (RTR depende de la restitución del eje mecánico del miembro, de la correcta colocación del implante y del balance de partes blandas. Los pacientes con gonartrosis asociada a una deformidad extraarticular, femoral o tibial, requieren de una cuidadosa evaluación y planificación preoperatoria con el objeto de decidir si la corrección del eje podrá realizarse mediante la resección ósea intraarticular, o si deberá asociarse una osteotomía extraarticular. Material y Método Se evaluaron 22 RTR (en 20 pacientes por gonartrosis asociada a deformidad extraarticular. La etiología de la deformidad extraarticular fue postraumática en 8 casos y postosteotomía en 14 (8 femorales y 6 tibiales. Resultados En todos los casos se realizó la corrección del eje del miembro mediante un RTR con cortes óseos intra articulares “inusuales”, sin que fuera necesario realizar una osteotomía. La evaluación clínica y funcional se realizó mediante el sistema de puntaje de la Knee Society2. El promedio de la evaluación clínica fue de 24,3 puntos en el prequirúrgico y 86 al año postoperatorio. Con respecto al puntaje funcional, paso de un promedio de 34 puntos en el prequirúrgico a 85,3 puntos al año. Conclusión No hay un criterio único en relación al tratamiento del paciente con gonartrosis sintomática asociada a una deformidad extraarticular. La corrección de la deformidad extraarticular por medio de cortes óseos intraarticulares ¨inusuales¨ es posible si estos no afectan las inserciones ligamentarias femorales ni tibiales. Este método puede aplicarse en desejes femorales de hasta 20° y tibiales de hasta 30° en el plano coronal. Mediante esta técnica hemos obtenido buenos resultados, a más de 5 años de seguimiento, en 20 de los 22 casos operados.

    This study was designed to evaluate the results of single-stage bilateral Pemberton's pericapsular osteotomy with or without open reduction and to demonstrate its advantages over two separate consecutive interventions in bilateral developmental dysplasia of the hip (DDH). This prospective study included 20 patients (14 girls, 6 boys; mean age 30 months; range 12 to 60 months) with bilateral DDH, who underwent single-stage bilateral Pemberton's pericapsular osteotomy with (14 patients, group A1) or without (6 patients, group A2) open reduction. Twenty patients (16 girls, 4 boys; mean age 24 months; range 13 to 47 months) with unilateral DDH, who underwent Pemberton's pericapsular osteotomy with (12 patients, group B1) or without (8 patients, group B2) open reduction were enrolled into the study as controls. Single- and two-stage procedures were compared with regard to improvement in the acetabular index, complications, mean duration of anesthesia, perioperative need for blood transfusion, length of hospital stay, initiation of walking, overall cost of antibiotic prophylaxis, and total hospital charge. There were no significant differences between A1 and B1, A2 and B2 groups with respect to mean age, gender, pre- and postoperative acetabular indices, and recovery times. However, duration of anesthesia, length of hospital stay, cost of antibiotic prophylaxis, and total hospital charges differed significantly. The amount of blood transfusion differed significantly only between groups A1 and B1. The length of hospital stay and cost of antibiotic prophylaxis in group A2 was twice as much as that of group B2. Increases in other parameters ranged between 22% to 37%. No early or late complications were encountered. Single-stage bilateral Pemberton's pericapsular osteotomy in patients with bilateral DDH seems to have significant advantages over two separate consecutive interventions. However, increased risks of bilateral osteotomies require that sufficiently equipped and

    Full Text Available In studies using isolated ovarian granulosa and thecal cells it is important to assess the degree of cross contamination. Marker genes commonly used for granulosa cells include FSHR, CYP19A1 and AMH while CYP17A1 and INSL3 are used for thecal cells. To increase the number of marker genes available we compared expression microarray data from isolated theca interna with that from granulosa cells of bovine small (n = 10 for both theca and granulosa cells; 3-5 mm and large (n = 4 for both theca and granulosa cells, > 9 mm antral follicles. Validation was conducted by qRT-PCR analyses. Known markers such as CYP19A1, FSHR and NR5A2 and another 11 genes (LOC404103, MGARP, GLDC, CHST8, CSN2, GPX3, SLC35G1, CA8, CLGN, FAM78A, SLC16A3 were common to the lists of the 50 most up regulated genes in granulosa cells from both follicle sizes. The expression in theca interna was more consistent than in granulosa cells between the two follicle sizes. Many genes up regulated in theca interna were common to both sizes of follicles (MGP, DCN, ASPN, ALDH1A1, COL1A2, FN1, COL3A1, OGN, APOD, COL5A2, IGF2, NID1, LHFP, ACTA2, DUSP12, ACTG2, SPARCL1, FILIP1L, EGFLAM, ADAMDEC1, HPGD, COL12A1, FBLN5, RAMP2, COL15A1, PLK2, COL6A3, LOXL1, RARRES1, FLI1, LAMA2. Many of these were stromal extracellular matrix genes. MGARP, GLDC, CHST8, GPX3 were identified as new potential markers for granulosa cells, while FBLN5, OGN, RAMP2 were significantly elevated in the theca interna.

    Full Text Available Se informa que la neumonía asociada a ventilación mecánica es un tipo particular de infección nosocomial frecuente en los pacientes críticos y se asocia con altas tasas de morbilidad y mortalidad. Su origen es polimicrobiano y depende de múltiples factores de riesgo como: edad, días de ventilación, poca movilización, alcalinización gástrica, trauma, coma y uso de medicamentos como: sedantes y bloqueadores, entre otros. Las estrategias fundamentales para la prevención de esta entidad, tienen como objetivo reducir el impacto de los factores de riesgo ya sean intrínsecos o extrínsecos. Su pronóstico depende del momento de aparición de los síntomas, por lo que se clasifica de inicio temprano, aquella que aparece antes de los 4 días de ventilación, producida por los gérmenes de la orofaringe, se asocia a baja mortalidad y generalmente es de buen pronóstico y la de inicio tardío que aparece después de los 5 días de apoyo ventilatorio, producida por cepas multirresistentes y de muy mal pronóstico. El diagnóstico es difícil por los múltiples criterios propuestos a través de los diferentes estudios realizados. Los emitidos por la Sociedad Americana del Tórax en 1999 son más específicos, pues reúnen las condiciones clínicas, microbiológicas y no microbiológicas, las cuales no son invasivas, resultan fáciles y rápidas de recoger y pueden aplicarse a cualquier grupo de edad, independientemente de la causa que provocó la enfermedad. El análisis microscópico directo y el conocimiento del mapa epidemiológico de cada servicio, permiten el inicio de un tratamiento empírico más efectivo. Aunque la tendencia actual en el tratamiento es la monoterapia, no existe un antibiótico ideal que cubra la totalidad del espectro de los microorganismos responsables de esta entidad.It is reported that pneumonia associated with mechanical ventilation is a particular type of nosocomial infection that is frequently found among critical

    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.

  5. Economic Diplomacy in Africa: The Impact of Regional Integration versus Bilateral Diplomacy on Bilateral Trade

    DEFF Research Database (Denmark)

    Afesorgbor, Sylvanus Kwaku

    The paper examines the impact of two main instruments of economic diplomacy — regional integration and commercial diplomacy on export flows among African states. We test whether there is any evidence of a trade-off or complementary interaction between these two instruments in trade facilitation. We...... compare the effects of these two instruments of economic diplomacy on bilateral trade by employing a gravity model for 45 African states over the period 1980-2005. The results show that bilateral diplomatic exchange is a relatively more significant determinant of bilateral exports among African states...... compared to regional integration. We also find a nuanced interaction between these two instruments of economic diplomacy: the trade–stimulating effect of diplomatic exchange is less pronounced among African countries that shared membership of the same regional bloc. Generally, this could mean...

    2016-12-01

    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. Further research is needed. Copyright © 2015 European Foot and Ankle Society. Published by Elsevier Ltd. All rights reserved.

  10. Surgical interventions for bilateral congenital cataract.

    Long, V; Chen, S

    2001-01-01

    Congenital cataracts are opacities of the lens in one or both eyes of children, causing a reduction in vision bad enough to require surgery. Cataract is the largest preventable cause of visual loss in childhood. Paediatric cataracts provide different challenges to those in adults. Intense inflammation, amblyopia and posterior capsule opacification can affect results of treatment. Two treatments commonly considered for congenital cataract are lensectomy and lens aspiration. The objective of this review is to assess the effects of surgical treatments for bilateral symmetrical congenital cataracts. Success is measured according to the vision attained and occurrence of adverse events. We searched the Cochrane Controlled Trials Register - CENTRAL (which includes the Cochrane Eyes and Vision Group specialised register), MEDLINE, EMBASE, the Science Citation Index and the reference list of the included study. We also contacted trial investigators and experts in the field for details of further studies. We included all prospective, randomised controlled trials that compared one type of cataract surgery to another or to no surgery, in children aged 15 years or younger with bilateral congenital cataracts. Two reviewers extracted data. No meta-analysis was performed. One trial met the inclusion criteria. This trial randomised 130 eyes of 65 children. Follow up of 56 children at three years found no difference in visual acuity between lensectomy and lens aspiration with primary capsulotomy. Secondary opacification developed at a higher rate in the lens aspiration group (66%) compared to the lensectomy group (2%). The two methods of surgery for bilateral congenital cataracts in this review have good visual results but the incidences of side effects differ. Further randomised trials are required to inform modern practice.

    Bilaterality is uncommon in Wilms' tumor, being present in 4% to 8% of the cases. We report the combined experience of two children's hospitals in one city over a 20-year period. We encountered nine cases of synchronous bilateral nephroblastoma (National Wilms' Tumor Study 3, stage V). Age at diagnosis ranged from 9 to 41 months (mean 23 months). There were five girls and four boys. Associated findings include nephroblastomatosis in three cases (33%), one of which also had a familial history; undescended testis in two cases; and minor anomalies in two other cases. Surgical treatment consisted of unilateral nephrectomy with contralateral partial nephrectomy or tumorectomy in six cases, nephrectomy with contralateral biopsy only in two cases, and the other patient had bilateral biopsies initially, followed at a later date by partial nephrectomy on one side. All patients received chemotherapy; actinomycin D (AMD) only was used in the oldest case, vincristine and AMD in five cases, to which was added cyclophosphamide in one case and adriamycin in two. Seven patients received radiation therapy. Seven out of the nine patients survived more than 2 years (77%); five are well, off chemotherapy, with no evidence of disease from 4 to 11 years after diagnosis. Two patients suffered from chronic renal failure and one died from complications after renal transplantation more than 19 years after diagnosis. The two patients who died from their disease presented with more advanced tumor. Therefore, the agressiveness of multimodal therapy can be tailored according to stage and histology, and effective chemotherapy allows maximal preservation of renal parenchyma in patients with stage I and II tumors

    Charpied, George L

    2007-01-01

    The pars interna/media (PIM) is a small muscle found in the human larynx that has not been successfully described in contemporary literature on laryngeal structure. The objective of this study was to describe the PIM's anatomy in detail. Thirteen human larynges obtained from postmortem examination were cleaned and preserved. Exposure of the PIM was through a lateral disarticulation of the cricothyroid joint and reflection of the cricothyroid muscle and the thyroid lamina. In the human, the PIM was found to be strap-like in form and to have two bellies with attachments to the medial surface of the thyroid cartilage at the root of the inferior horn and anteriosuperior cricoid arch. It appears to be innervated by a middle division, vestibular branch, of the internal superior laryngeal nerve. The average fiber diameter is 40 mum. Its type 1-to-type 2 fiber ratio places it within the range of other intrinsic laryngeal muscles. A muscle spindle was identified in medial bundle at the PIM's thyroid attachment. Thyroid medial surface attachment is within few millimeters of the muscular process of the arytenoid cartilage. These data show that the PIM is a robust muscle and deserves attention anatomically. Its orientation within the thyroid and nonrecurrent laryngeal nerve innervations of the human PIM may place it in the vocal fold tensor group rather than the laryngeal sphincter group. It is possible the PIM reports on cricothyroid distance and right versus left cricothyroid joint stresses. Electromyographic examination of the PIM in the Rhesus larynx may help elucidate its physiology to elaborate its human physiology. Copyright 2007 S. Karger AG, Basel.

    {sup 18}F-Fluoride PET/CT is a relatively undervalued diagnostic test to measure bone metabolism in bone diseases. Hyperostosis cranialis interna (HCI) is a (hereditary) bone disease characterised by endosteal hyperostosis and osteosclerosis of the skull and the skull base. Bone overgrowth causes entrapment and dysfunction of several cranial nerves. The aim of this study is to compare standardised uptake values (SUVs) at different sites in order to quantify bone metabolism in the affected anatomical regions in HCI patients. Nine affected family members, seven non-affected family members and nine non-HCI non-family members underwent {sup 18}F-fluoride PET/CT scans. SUVs were systematically measured in the different regions of interest: frontal bone, sphenoid bone, petrous bone and clivus. Moreover, the average {sup 18}F-fluoride uptake in the entire skull was measured by assessing the uptake in axial slides. Visual assessment of the PET scans of affected individuals was performed to discover the process of disturbed bone metabolism in HCI. {sup 18}F-Fluoride uptake is statistically significantly higher in the sphenoid bone and clivus regions of affected family members. Visual assessment of the scans of HCI patients is relevant in detecting disease severity and the pattern of disturbed bone metabolism throughout life. {sup 18}F-Fluoride PET/CT is useful in quantifying the metabolic activity in HCI and provides information about the process of disturbed bone metabolism in this specific disorder.

    Full Text Available Orthodontic treatment aims to improve esthetics, function and structural balance. In some rare circumstances, the clinician may not be able to achieve the ideal treatment goals because of complex multiple orthodontic problems, which may include significant mutilation of the dentition. Brodie bite, a complete buccal posterior crossbite is a problem, which confronts clinicians with often complex variable etiology. The following case report demonstrates treatment of bilateral buccal nonocclusion that is mainly due to a maxillary dental arch issue rather than mandibular retrognathism.

    Acupuncture is becoming increasingly popular in the United States for a wide variety of uses, ranging from the treatment of chronic back pain to aiding in addiction therapy. As this form of complementary and alternative medicine becomes more prevalent in certain areas of the country, it is of paramount importance that the emergency physician be familiar with its methods and potential complications. In general, acupuncture is perceived as fairly safe. However, it is not without risks or side effects. In this case report, we discuss the history, methods, and common complications of acupuncture in the context of a patient who presented to the Emergency Department (ED) with bilateral pneumothoraces secondary to acupuncture therapy.

    Full Text Available Nasoalveolar cysts, which originate from epithelial remnants of nasolacrimal duct, are nonodontogenic soft tissue lesions of the upper jaw. These cysts are thought to be developmental and are presented with fullness in the upper lip and nose, swelling on the palate, and sometimes nasal obstruction. Because of cosmetic problems, they are often diagnosed at an early stage. These lesions are mostly revealed unilaterally but also can be seen on both sides. In this case report, a patient who complained of nasal obstruction and then diagnosed with bilateral nasoalveolar cysts and treated by sublabial excision is presented and clinical features and treatment approaches are discussed with the review of literature.

    Wallis, Kate E; Blum, Nathan J; Waryasz, Stephanie A; Augustyn, Marilyn

    Sonia is a 4 years 1 month-year-old girl with Waardenburg syndrome and bilateral sensorineural hearing loss who had bilateral cochlear implants at 2 years 7 months years of age. She is referred to Developmental-Behavioral Pediatrics by her speech/language pathologist because of concerns that her language skills are not progressing as expected after the cochlear implant. At the time of the implant, she communicated using approximately 20 signs and 1 spoken word (mama). At the time of the evaluation (18 months after the implant) she had approximately 70 spoken words (English and Spanish) and innumerable signs that she used to communicate. She could follow 1-step directions in English but had more difficulty after 2-step directions.Sonia was born in Puerto Rico at 40 weeks gestation after an uncomplicated pregnancy. She failed her newborn hearing test and was given hearing aids that did not seem to help.At age 2 years, Sonia, her mother, and younger sister moved to the United States where she was diagnosed with bilateral severe-to-profound hearing loss. Genetic testing led to a diagnosis of Waardenburg syndrome (group of genetic conditions that can cause hearing loss and changes in coloring [pigmentation] of the hair, skin, and eyes). She received bilateral cochlear implants 6 months later.Sonia's mother is primarily Spanish-speaking and mostly communicates with her in Spanish or with gestures but has recently begun to learn American Sign Language (ASL). In a preschool program at a specialized school for the deaf, Sonia is learning both English and ASL. Sonia seems to prefer to use ASL to communicate.Sonia receives speech and language therapy (SLT) 3 times per week (90 minutes total) individually in school and once per week within a group. She is also receiving outpatient SLT once per week. Therapy sessions are completed in English, with the aid of an ASL interpreter. Sonia's language scores remain low, with her receptive skills in the first percentile, and her

  3. Hypersexuality following bilateral thalamic infarction: case report

    Directory of Open Access Journals (Sweden)

    Mutarelli Eduardo G.

    2006-01-01

    Full Text Available Hypersexuality is a rare but well recognized condition following brain injury. It has been described secondarily to dysfunction in the hypothalamus, the temporal and frontal lobes. We report a 63 year-old man that developed neuropsychological disturbances with hypersexuality as a prominent feature, disinhibition and moderate memory loss, hypersomnia and irritability after a bilateral paramedian thalamic infarction. A SPECT showed frontal hypoperfusion. We believe that these findings are expression of frontal-subcortical circuits dysfunction, particularly the orbitofrontal circuit, secondary to dorso medial thalamic infarction which probably plays a role in the determination of human sexual behavior. This case favors a thalamic modulation of frontal function.

    The aims of this field trial were to describe the clinical-pathologic findings in calves with otitis media (OM) and media-interna (OMI), to evaluate, through the development of a scoring system, the effectiveness of a standardized therapeutic protocol, and to identify the causative pathogens and their possible correlation with concurrent respiratory disease. All animals underwent physical and neurological examinations at three experimental time points: at diagnosis/beginning of treatment (T0), 1 week (T1) and 2 weeks (T2) after therapy was started, respectively. Follow-up telephone interviews with animal owners were conducted 1 month later. The therapeutic protocol consisted of tulathromycin (Draxxin®; Zoetis), oxytetracycline hydrochloride (Terramicina 100®; Zoetis), and carprofen (Rimadyl®; Zoetis). Twenty-two calves were enrolled. Physical and otoscopic examination at T0 revealed monolateral and bilateral otorrhea in 16 and 6 calves, respectively, with peripheral vestibular system involvement in calves presenting with neurological signs (n = 17; 77 %). A significant improvement of clinical and neurological scores was observed in 20 (90 %) calves, a full recovery in only 1 (5 %). One calf worsened between T0 and T1 and it was removed from the study. None of the other animals showed a worsening of clinical conditions and/or required further treatments at one month follow up. Mycoplasma bovis was isolated in 89 % of the affected ears either alone or together with P. multocida (n = 5), Streptococcus spp. (n = 1), Staphylococcus spp. (n = 1), and Pseudomonas spp. (n = 1). M. bovis either alone or together with these bacteria was also isolated from the upper and/or lower respiratory tract in 19 (86 %) calves. This is the first prospective study to evaluate the effectiveness of a standardized therapeutic protocol for the treatment of OM/OMI in calves. The therapy led to clinical improvement in the majority of the calves. Persistence of mild clinical

  5. Improving efficiency in bilateral emission trading

    1998-01-01

    When environmental damages from emissions are spatially nonuniform, permit trading has been modeled most often as a 'pollution offset program' in which emission permits are traded between agents, subject to constraints on ambient air quality. To date the institution envisioned to implement such a program involves trading on a bilateral and sequential basis. However, simulation studies indicate that the sequence of trades may alter the outcome and undermine the cost savings from a pollution offset program. This paper identifies a design for the trading institution that tends to overcome this phenomenon and improve the efficiency of equilibria obtained in a simulation model. We model a bilateral trading process for the reduction of sulfur dioxide emissions with a stochastic description of the sequence of trades within groups of nations in Europe. When trading takes place between disaggregated, stylistic representations of economic enterprises, rather than between national governments, a significantly greater portion of potential savings is achieved. In fact, under most sets of assumptions, approximate first order stochastic dominance is achieved wherein the more decentralized the trading agents, the greater the expected savings from a trading program. 4 figs., 2 tabs., 31 refs

    Full Text Available Microspherophakia is rare bilateral congenital anamoly of the crystalline lens. The condition may be isolated , familial or it may be associated with systemic affections like Marfan's syndrome , Weil - Marchesani syndrome , hyperlysinemia and congenital rubella. Microspherophakia results in lenticular myopia , lens dislocation , usually inferiorly and inverse glaucoma. We present a case in a 8 year old child who presented with bilateral microspherophakia and anterior dislocation of lens of right eye. visual acuity in right eye was counting fingers close to face and i n left eye 6/60.IOP with perkins applanation tonometer was 30mmHg in right eye 22mmHg in left eye , cornea was hazy due to edema , anterior chamber was shallow in both eye patient was managed with emergency lens extraction of right eye and secondary ACIOL im plantation.

    Full Text Available A 48-year-old woman sustained simultaneous isolated bilateral greater trochanteric fracture, following a road traffic accident. The patient presented to us 1 month after the injury. She presented with complaints of pain in the left hip and inability to walk. Roentgenograms revealed displaced comminuted bilateral greater trochanter fractures. The fracture of the left greater trochanter was reduced and fixed internally using the tension band wiring technique. The greater trochanter fracture on the right side was asymptomatic and was managed conservatively. The patient regained full range of motion and use of her hips after a postoperative follow-up of 6 months. Isolated fractures of the greater trochanter are unusual injuries. Because of their relative rarity and the unsettled controversy regarding their etiology and pathogenesis, several methods of treatment have been advocated. Furthermore, the reports of this particular type of injury are not plentiful and the average textbook coverage afforded to this entity is limited. In our study we discuss the mechanism of injury and the various treatment options available.

  8. Unusual Bilateral Rim Fracture in Femoroacetabular Impingement

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available This is a report of one case of bilateral acetabular rim fracture in association with femoroacetabular impingement (FAI, which was treated with a hip arthroscopic procedure, performing a partial resection, a labral reinsertion, and a subsequential internal fixation with cannulated screws. Up to date, there are in the literature only two reports of rim fracture and “os acetabuli” in association with FAI. In the case we present, the pincer and cam resection were performed without complications; the technique used was published previously. With this technique the head of the screw lays hidden by the reattached labrum. We removed partially the fractured rim fragment and the internal fixation of the remaining portion was achieved with a screw. In the event of a complete resection of the fragment, it would have ended with a LCE angle of 18° and a high probability of hip instability. We believe that this bilateral case helps establish the efficacy and reproducibility of the technique described by Larson.

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

    Cervical spondylolysis, which is defined as a cleft between the superior and inferior articular facets of the articular pillar, is a rare condition. The sixth cervical vertebra (C6) is the level most commonly affected. Cases involving C2, C3, C4, or C5 have also been reported. However, to date, no case of C7 spondylolysis has been reported. To present a rare case of bilateral spondylolysis of the seventh cervical vertebra (C7) in a 58-year-old man. A case report. A 58-year-old man visited our hospital with chronic posterior neck pain radiating to the left upper extremity. Magnetic resonance imaging (MRI) study revealed left foraminal disc herniations at C5-C6 and C6-C7. Cervical spondylolysis involving C7 was discovered incidentally during computed tomography (CT)-guided transforaminal steroid injection. Plain radiographs, CT images, and MRIs were reviewed thoroughly once again. The patient's symptoms were relieved after he received CT-guided transforaminal steroid injections. Plain radiographs revealed a radiolucent defect in the articular pillar and cleft at the spinous process of C7. Computed tomography confirmed bilateral spondylolysis and spina bifida occulta of the C7 vertebra. Magnetic resonance imaging revealed absence of edema, which was suggestive of a chronic lesion. Involvement of C7 is not exceptional in a case of cervical spondylolysis. Copyright © 2010 Elsevier Inc. All rights reserved.

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.

    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.

    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.

    Vocal cord paralysis is a rare cause of obstructive sleep apnea syndrome (OSAS). Recurrent laryngeal nerve injury after thyroid gland surgery is one of the leading causes of acquired vocal cord paralysis. A 46-year-old woman with OSAS due to bilateral abductor vocal cord paralysis was presented. She had thyroidectomy 30 years ago and had a weak, breathy voice. She had been referred with a history of high-pitched snoring, apnea witnessed by her spouse, and excessive daytime sleepiness for the last 5 years. Full-night polysomnography revealed that her apnea-hypopnea index was 72/h and minimal oxygen saturation level was 81%. There was no REM and deep sleep periods. Ear-nose-throat consultation offered an endoscopic bilateral posterior cordotomy operation via microscopic suspension laryngoscopy (MLS) as a treatment option. Instead of using a nasal positive airway pressure (nCPAP) device, she was treated surgically. Her OSAS resolved completely within 5 months of the surgery. Her phonation was preserved, and symptoms such as snoring and hypersomnolance disappeared. In OSAS patients with bilateral vocal cord paralysis, MLS-associated bilateral posterior cordotomy can be a choice of treatment as an alternative to nCPAP application.

    Recurrence of hypercortisolism in patients after bilateral adrenalectomy for Cushing disease is extremely rare. We present a 27-year-old man who previously underwent bilateral adrenalectomy for Cushing disease with complete clinical resolution. Cushingoid features recurred 12 years later, with bilateral testicular enlargement. Hormonal tests confirmed adrenocorticotropic hormone (ACTH)-dependent Cushing disease. Surgical resection of the testicular tumors led to clinical and biochemical remission. Gene expression analysis of the tumor tissue by quantitative polymerase chain reaction showed high expression of all key steroidogenic enzymes. Adrenocortical-specific genes were 5.1 × 105 (CYP11B1), 1.8 × 102 (CYP11B2), and 6.3 × 104 (MC2R) times higher than nonsteroidogenic fibroblast control. This correlated with urine steroid metabolome profiling showing 2 fivefold increases in the excretion of the metabolites of 11-deoxycortisol, 21-deoxycortisol, and total glucocorticoids. Leydig-specific genes were 4.3 × 101 (LHCGR) and 9.3 × 100 (HSD17B3) times higher than control, and urinary steroid profiling showed twofold increased excretion of the major androgen metabolites androsterone and etiocholanolone. These distinctly increased steroid metabolites were suppressed by dexamethasone but unresponsive to human chorionic gonadotropin stimulation, supporting the role of ACTH, but not luteinizing hormone, in regulating tumor-specific steroid excess. We report bilateral testicular tumors occurring in a patient with recurrent Cushing disease 12 years after bilateral adrenalectomy. Using mRNA expression analysis and steroid metabolome profiling, the tumors demonstrated both adrenocortical and gonadal steroidogenic properties, similar to testicular adrenal rest tumors found in patients with congenital adrenal hyperplasia, suggesting the presence of pluripotent cells even in patients without congenital adrenal hyperplasia.

    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.

    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 Mielolipomas são tumores benignos relativamente raros, freqüentemente associados à glândula adrenal. Geralmente são não-funcionantes, assintomáticos e medem menos de 5 cm. Mielolipomas adrenais bilaterais e gigantes são raros. Relatamos o primeiro caso de mielolipoma gigante bilateral da glândula adrenal da literatura latino-americana: paciente do sexo feminino, 57 anos, com queixa de dor no flanco esquerdo. A tomografia computadorizada do abdome mostrou massas bilaterais da glândula adrenal, medindo a direita 9 x 7 x 6,5 cm e a esquerda 23 x 19 x 8 cm. As massas eram radiologicamente consistentes com tecido adiposo. O diagnóstico pré-operatório foi de lipossarcoma. A paciente foi submetida à laparotomia com retirada das massas. O exame microscópico diagnosticou mielolipomas bilaterais. Embora sejam tumores benignos, seu tratamento deve ser cirúrgico, pois somente o exame anatomopatológico pode descartar uma neoplasia maligna.Myelolipomas are relatively rare benign tumors, frequently associated with the adrenal glands. Usually, they are non-functioning, asymptomatic and measure less than 5 cm. Bilateral giant adrenal myelolipomas are rare. We report the first case of bilateral giant adrenal myelolipomas of the Latin American literature: a 57-year old woman who presented with left abdominal pain. The computed tomography scanning revealed bilateral suprarenal masses measuring 9 x 7 x 6.5 cm on the right and 23 x 19 x 8 cm on the left. The masses were radiographically consistent with fatty tissue. The preoperative diagnosis was liposarcoma. Surgery was performed with excision of the masses. The histologic analysis identified bilateral adrenal myelolipomas. Although they are benign tumors, surgery must be performed because only the histologic analysis can exclude malignancy.

    Full Text Available Introduction: Sudden sensorineural hearing loss (SSNHL is an important otological emergency. Up to 90% of the cases are idiopathic. Cerebral venous thrombosis (CVT is an extremely rare identifiable cause as it only represents 0.5% of all strokes.   Case Report: In this paper, an unusual case of bilateral SSNHL secondary to bilateral CVT with rapid and complete recovery is reported. The patient presented with sudden bilateral hearing loss associated with some neurological symptoms. Initial computed tomography (CT venography revealed a CVT of bilateral transverse sinuses. The patient was started on an anticoagulant and imaging was repeated after five days, revealing the absence of the thrombosis. Serial pure tone audiometry (PTA showed complete recovery of bilateral hearing within 10 days.   Conclusion: Early detection and intervention may fasten hearing recovery and improve the quality of life. The immediate restoration of venous blood flow and intracranial pressure may lead to the complete recovery of bilateral hearing loss.

    Conclusion: The early functional recovery of bilateral TKA patient lags behind that of unilateral TKA patient for the first 5 days, becomes equal by the 14 th day and remains equal till 1 year after surgery. Bilateral TKA patients regain their preoperative functional status by 6 weeks against 3 months for unilateral TKA. The operative status of the contralateral knee makes no difference to early functional recovery after unilateral TKA. With bilateral TKA, there is no difference in pain and ROM parameters.

    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

    To demonstrate and evaluate the scan time and quantitative accuracy of simultaneous bilateral-knee imaging compared with single-knee acquisitions. Hardware modifications and safety testing was performed to enable MR imaging with two 16-channel flexible coil arrays. Noise covariance and sensitivity-encoding g-factor maps for the dual-coil-array configuration were computed to evaluate coil cross-talk and noise amplification. Ten healthy volunteers were imaged on a 3T MRI scanner with both dual-coil-array bilateral-knee and single-coil-array single-knee configurations. Two experienced musculoskeletal radiologists compared the relative image quality between blinded image pairs acquired with each configuration. Differences in T 2 relaxation time measurements between dual-coil-array and single-coil-array acquisitions were compared with the standard repeatability of single-coil-array measurements using a Bland-Altman analysis. The mean g-factors for the dual-coil-array configuration were low for accelerations up to 6 in the right-left direction, and minimal cross-talk was observed between the two coil arrays. Image quality ratings of various joint tissues showed no difference in 89% (95% confidence interval: 85-93%) of rated image pairs, with only small differences ("slightly better" or "slightly worse") in image quality observed. The T 2 relaxation time measurements between the dual-coil-array configuration and the single-coil configuration showed similar limits of agreement and concordance correlation coefficients (limits of agreement: -0.93 to 1.99 ms; CCC: 0.97 (95% confidence interval: 0.96-0.98)), to the repeatability of single-coil-array measurements (limits of agreement: -2.07 to 1.96 ms; CCC: 0.97 (95% confidence interval: 0.95-0.98)). A bilateral coil-array setup can image both knees simultaneously in similar scan times as conventional unilateral knee scans, with comparable image quality and quantitative accuracy. This has the potential to improve the value of

    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

Materiales y métodos. Tras las sesiones presenciales, el material docente se deposita en la página web o campus virtual de la asignatura, a partir del cual los estudiantes responden a seis cuestionarios. Resultados. En el curso 2008-2009 se matricularon 61 alumnos de cuarto a sexto curso. Veintisiete alumnos (44,26% respondieron correctamente a más de la mitad de las preguntas, el 31,15% no alcanzó esta cifra y el 24,59% no completó el programa de evaluaciones. Las puntuaciones más altas se han dado de las pruebas funcionales respiratorias, y las más bajas, en la evaluación de la radiografía de tórax. Conclusiones. No es fácil la evaluación de competencias clínicas. El coste de realización de las pruebas y la resistencia de los estudiantes a ser evaluados quedan soslayados en esta experiencia, donde los estudiantes se matriculan voluntariamente. La sencillez del proyecto permitiría evaluar en competencias clínicas a todos los estudiantes de la facultad en los cursos clínicos cuando aún es posible la formación. Una vez comprobado que los estudiantes tienen una buena aceptación del sistema propuesto, se podría diseñar un sistema de acceso a créditos docentes y un plan de formación específica en las materias no superadas.

  13. Medida Socioeducativa de Internação: dos Corpos Dóceis às Vidas Nuas

    Andrea Cristina Coelho Scisleski

    Full Text Available O presente artigo tem como objetivo a problematização dos modos pelos quais a tecnologia disciplinar, presente nas medidas socioeducativas de internação direcionadas aos jovens em conflito com a lei, vem sendo operacionalizada. Tomamos como fio condutor as reflexões de Michel Foucault e Giorgio Agamben para problematizar a vida enquanto objeto político a ser governado para determinado fim e que sofre intervenções não apenas para seu fortalecimento, mas que levam à desproteção jurídica e à morte política, ou mesmo biológica. A investigação se desenvolveu em três momentos metodológicos: oitiva de audiências na Vara da Infância e da Juventude, visita a uma unidade educacional de internação e leitura de processos jurídicos e das normativas legais voltadas para a população em questão. Assim, por meio do que encontramos na pesquisa, entende-se que a tecnologia disciplinar, do modo que vem sendo utilizada nas medidas socioeducativas de internação, assemelha-se mais a um dispositivo de controle com o objetivo meramente de docilizá-los, reduzindo o sujeito à vida nua; isto é, como mero corpo biológico que sofre efeitos de uma ação, do que propriamente um método socioeducativo como estabelecem o Estatuto da Criança e do Adolescente e o Sistema Nacional de Atendimento Socioeducativo.

    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.

    Bilateral simultaneous facial paralysis is an extremely rare clinical entity. Unlike the unilateral form, bilateral facial paralysis seldom falls into Bell's category. It is most often a special finding in a symptom complex of a systemic disease; many of them are potentially life-threatening, and therefore the condition warrants urgent medical intervention. Lyme disease, Guillian-Barre syndrome, Bell's palsy, leukemia, sarcoidosis, bacterial meningitis, syphilis, leprosy, Moebius syndrome, infectious mononucleosis, and skull fracture are the most common cause of bilateral facial paralysis. Here we present a 16-year-old patient with bilateral simultaneous Bell's palsy.

    1978-11-01

    The memory loss associated with bilateral and nondominant unilateral ECT was assessed with verbal memory tests known to be sensitive to left temporal lobe dysfunction and with nonverbal memory tests known to be sensitive to right temporal lobe dysfunction. Bilateral ECT markedly impaired delayed retention of verbal and nonverbal material. Right unilateral ECT impaired delayed retention of nonverbal material without measurably affecting retention of verbal material. Nonverbal memory was affected less by right unilateral ECT than by bilateral ECT. These findings, taken together with a consideration of the clinical efficacy of the two types of treatment, make what appears to be a conclusive case for unilateral over bilateral ECT.

    Neuroblastoma is one of the most common malignant tumors of childhood, with 40 % arising in the adrenal glands. Bilateral adrenal involvement from synchronous development or metastatic spread of the tumor is seen in less than 10 % of children with neuroblastoma [1[. Neuroblastoma rarely presents as a cystic suprarenal mass that is difficult to differentiate from adrenal hemorrhage, extralobar sequestration, or dilated upper-pole renal calyces. To our knowledge, bilateral cystic neuroblastoma has not been previously reported. We present a case of bilateral cystic adrenal neuroblastoma to demonstrate the imaging features of this unusual entity, and to expand the differential diagnosis of bilateral cystic suprarenal masses in an infant.

    The effect of bilateral application of bone-anchored hearing aids (BAHAs) was examined in terms of directional hearing and speech recognition in quiet and in noise in four patients with bilateral congenital atresia who, out of pure necessity, had been using a unilateral bone-conduction hearing aid since early life. This study comprised a prospective clinical evaluation in a single subject design; four patients with bilateral congenital atresia originating from the Nijmegen BAHA series participated. Three patients had Treacher Collins syndrome. All four patients had conductive, most probably, symmetrical, hearing loss. Recently these patients had applied for a second BAHA and were subsequently fitted bilaterally. With two BAHAs, all four patients showed significant improvement in sound localization. Also, speech perception in quiet showed significant improvement with bilateral application, and a significant improvement was found in speech perception in noise in three patients. These results suggest that patients with congenital conductive, symmetrical hearing loss will benefit from bilateral BAHAs.

    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.

    External beam radiotherapy (EBRT) for retinoblastoma has traditionally been done with conventional radiotherapy techniques which resulted high doses to the surrounding normal tissues. A 20 month-old girl with group D bilateral retinoblastoma underwent intensity modulated radiotherapy (IMRT) to both eyes after failing chemoreduction and focal therapies including cryotherapy and transpupillary thermotherapy. In this report, we discuss the use of IMRT as a method for reducing doses to adjacent normal tissues while delivering therapeutic doses to the tumour tissues compared with 3-dimensional conformal radiotherapy (3DCRT). At one year follow-up, the patient remained free of any obvious radiation complications. Image guided IMRT provides better dose distribution than 3DCRT in retinoblastoma eyes, delivering the therapeutic dose to the tumours and minimizing adjacent tissue damage

    Emphysematous pyelonephritis (EPN) is a serious infectious disease that occurs more frequently in diabetic patients. Radiological studies are indispensable for distinguishing between the two types since each is associated with a markedly different prognosis. We present a case of bilateral EPN diagnosed as type I on the basis of computed tomography findings, differentiating it from type II EPN, taking into account the prognostic value of this distinction. Type I EPN is characterized by the destruction of the renal parenchyma, a mottled or linear gas pattern and the absence of renal and perirenal fluid collection. Type II EPN is characterized by a loculated or bubbly gas pattern, the existence of fluid collection and less marked renal destruction. Type I is more aggressive and is associated with high rate of mortality. (Author) 7 refs

    Current models of bilateral trade neglect the effects of income distribution. This paper addresses the issue by accounting for non-homothetic consumer preferences and hence investigating the role of income distribution in the context of the gravity model of trade. A theoretically justified gravity model is estimated for disaggregated trade data (Dollar volume is used as dependent variable) using a sample of 104 exporters and 108 importers for 1980-2003 to achieve two main goals. We define and calculate new measures of income distribution similarity and empirically confirm that greater similarity of income distribution between countries implies more trade. Using distribution-based measures as a proxy for demand similarities in gravity models, we find consistent and robust support for the hypothesis that countries with more similar income-distributions trade more with each other. The hypothesis is also confirmed at disaggregated level for differentiated product categories.

    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.

  11. Bilaterally Weighted Patches for Disparity Map Computation

    Directory of Open Access Journals (Sweden)

    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.

    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.

    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.

    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.

    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.

En estos enfermos el trasplante renal ofrece excelentes tasas de supervivencia del injerto y del receptor a largo plazo, por lo que pueden ser trasplantados cuando la enfermedad está en remisión. Sin embargo, la amenaza de recidivas de la enfermedad en el injerto se mantiene, aunque, con las modernas pautas de inmunosupresión, su incidencia es menor. Presentamos el caso de un varón diagnosticado de glomerulonefritis extracapilar tipo III C-ANCA (+ que desarrolló una recidiva de la enfermedad en el injerto renal 8 años después de ser trasplantado. La intensificación de la inmunosupresión con plasmaféresis consiguió controlar la enfermedad.

    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.

Determinar las principales características epidemiológicas, clínicas y microbiológicas de una epidemia de neumonía asociada a ventilación mecánica en una unidad de cuidados intensivos en Mérida, Yucatán. MATERIAL Y MÉTODOS. Se diseñó un estudio prospectivo y observacional de 11 meses para determinar incidencia, mortalidad, reservorios potenciales, agentes etiológicos y sus patrones de sensibilidad antimicrobiana. RESULTADOS. La incidencia de neumonía asociada a ventilador fue de 74%. La mortalidad cruda fue de 88%, comparada con una mortalidad esperada de 19.5%. Se aislaron bacterias gramnegativas en 98% de los cultivos, de las cuales 46% fueron sensibles a cefalosporinas de tercera generación, 59% a cefalosporinas de cuarta generación, 70% a ciprofloxacina y 100% a imipenem. Se aislaron Klebsiella pneumoniae y Pseudomonas aeruginosa de algunos circuitos del ventilador y el lavado. CONCLUSIONES. La elevada incidencia de neumonía y la mortalidad asociada en esta unidad de cuidados intensivos se pueden atribuir a la falta de medidas de control de infecciones y a una elevada prevalencia de gérmenes multirresistentes que se relaciona con el uso desmesurado e irracional de antibióticos.

Os procedimentos metodológicos seguiram a linha qualitativa, por meio da pesquisa descritiva e aplicada. Foram entrevistadas sete das maiores empresas catarinenses em número de funcionários. Utilizou-se análise documental e de conteúdo. Quanto aos resultados, a consultoria interna auxilia principalmente nas etapas de socialização e externalização do conhecimento. Além disso, se implementada na sua totalidade e dada autonomia ao consultor interno, permite uma maior interação nos níveis individual, grupal e organizacional descritos por Sabbag (2007. Assim, pode-se perceber que as empresas que possuem maior grau de autonomia, bem como maior nível de implementação são aquelas que os processos são mais compartilhados, socializados e internalizados pelos funcionários. Dessa forma, pode-se afirmar que, nas empresas analisadas, o desenvolvimento dos processos de CIRH catalisa os resultados da Gestão do Conhecimento nas mesmas.

    Full Text Available Transient osteoporosis of the hip (TOH is a rare disorder characterized by acute severe coxalgia and temporary osteopenia in the proximal femur. Although most cases were unilateral or staged bilateral TOH, some authors reported that the pregnant patients simultaneously had TOH in their bilateral hips. However, there has been no report of simultaneous bilateral TOH in the patient without pregnancy. A 25-year-old Japanese woman without pregnancy had acute simultaneous bilateral hip pain. Plain X-ray of the bilateral hips did not show a periarticular osteopenia. However, magnetic resonance image obtained one week after the onset demonstrated increased T2-weighted signal intensity and decreased T1-weighted signal intensity in the bilateral femoral heads. She was treated conservatively, and follow-up magnetic resonance image at seven weeks after the onset returned to normal bone marrow signal intensity. Her bilateral coxalgia subsided gradually. At one year after the onset, she had no sign of symptomatic flair. Our experience with this case indicates that recognizing the possibility of simultaneous bilateral TOH is important unless the patient is pregnant, and magnetic resonance image is predictable test to make a diagnosis of TOH, even in the absence of abnormal finding on plain X-ray.

    The purpose of this study was to explore the validity of computerized scaling of bilateral, motor coordination in children 4-6 years of age. There were 623 children with an average age of 5, years and 2 months (standard deviation=6 months) that participated. The 290 girls (46.5%) and 333, boys (53.5%) were from a purposive sample taken from public and private kindergartens in Taiwan. The computerized bilateral motor coordination test included two subtests, bilateral coordination, movements and projected actions. The motion analysis, with mark position and contour motion, was, used to collect important variables from the subtests. Using the judgments of the experts as the, criterion standards, the accuracy, sensitivity, and specificity of the tool were calculated to evaluate the, validity of the computerized bilateral motor coordination test. The accuracy, sensitivity, and, specificity of the bilateral coordination movement subtests were on average 83.9%, 86.4%, and 83.1%, respectively. The accuracy, sensitivity, and specificity of the projected action subtests were on average, 90.5%, 88.1%, and 90.4%, respectively. The computerized bilateral motor coordination tests showed, an average accuracy of 86.3%, a sensitivity of 87.0%, and a specificity of 85.8%. The computerized, bilateral motor coordination test could be a valuable tool when used to identify problems of bilateral, motor coordination and in permitting early intervention to remedy these problems.

    The aim of this article is to report the MRI features of bilateral parotid haemangiomas of infancy and highlight the diagnostic and prognostic value of MRI especially with regard to those lesions that may cause respiratory compromise. Retrospective review of MRI scans in six infants with bilateral parotid haemangiomas. The bilateral haemangiomas were symmetrical in all but one patient. On T1-weighted images the masses were isointense to muscle and on T2 they were hyperintense with numerous small vessels giving a septated appearance. There was vivid enhancement with gadolinium in all cases. In three patients, deep bilateral extensions were demonstrated involving the parapharyngeal spaces resulting in respiratory compromise which required tracheostomy. Bilateral parotid haemangiomas are rare, but when present may have deep extensions, which can result in respiratory compromise requiring tracheostomy. (orig.)

    Full Text Available Background. The incidence of tubal ectopic gestation caused by schistosomiasis induced tubal pathology is undocumented in this environment, which may be due to rarity of this pathology. Bilateral tubal gestation is common in patients that have undergone in vitro fertilization. We report a hitherto undocumented case of spontaneous bilateral ectopic gestation following tubal schistosomiasis. Case Report. Mrs. OB was a 32-year-old G4P3+0 (3 alive woman who complained of abdominal pain and bleeding per vaginam of 4 and 2 days’ duration respectively following 8 weeks of amenorrhea. A clinical impression of ruptured ectopic gestation was confirmed by ultrasound scanning. She had bilateral salpingectomy with histology of specimens showing bilateral ectopic gestation with Schistosoma haematobium induced salpingitis (findings of Schistosoma haematobium ova noted on slide. Conclusion. Schistosoma induced salpingitis is a rare but possible cause of bilateral tubal gestation.

    Full Text Available Introducción: La enfermedad de Ménière se caracteriza por síntomas cocleares y vestibulares. Puede ser unilateral o bilateral. Cuando la pérdida de audición asociada es severa-profunda de forma bilateral o unilateral pero con problemas de audición en el otro oído, dicha audición puede beneficiarse de un implante coclear. Si además, presenta crisis de vértigo y Tumarkin refractarias al tratamiento médico, se puede plantear la realización simultánea de una laberintectomía quirúrgica y colocación de un implante coclear. Descripción: Se describe el caso de un paciente con enfermedad de Ménière bilateral con hipoacusia neurosensorial profunda de oído derecho con fluctuaciones auditivas izquierdas que asocia crisis vertiginosas y de Tumarkin sin respuesta a corticoides orales e intratimpánicos ni a gentamicina intratimpánica. Se le realizó una laberintectomía quirúrgica con implante coclear en el mismo acto quirúrgico anticipándonos al probable deterioro auditivo contralateral. Posteriormente presenta buen rendimiento del implante y desaparición de las crisis del oído intervenido. Discusión: El objetivo del tratamiento es controlar las crisis preservando la función, pero en pacientes en los que las medidas conservadoras fallan, se han de considerar otras más destructivas como es la laberintectomía química, que consigue altas tasas de control de las crisis, y el implante coclear, indicado para restaurar la audición en el oído afectado por enfermedad de Ménière. Si ambas se realizan en un mismo tiempo quirúrgico, se consigue reducir riesgos asociados con otros procedimientos quirúrgicos y anestésicos y evitar las modificaciones histológicas tras una laberintectomía química que dificultarían la posterior colocación del implante colear.

O objetivo do estudo foi avaliar a percepção de auditores internos e auditados em relação às práticas de auditoria interna de uma empresa brasileira do setor energético. A pesquisa, um estudo de caso com a utilização de fontes primárias, analisou diferentes aspectos da atividade de auditoria interna, incluindo a capacitação dos auditores e características associadas a um bom trabalho de auditoria. Auditores internos e auditados apontaram a preparação do auditor, a qualidade das recomendações de auditoria e a orientação para o risco como os fatores de maior influência sobre a qualidade do serviço de auditoria interna, corroborando o disposto na literatura. Também apresentaram percepção positiva sobre a contribuição da auditoria interna para a melhoria do desempenho dos processos, a melhoria da estrutura de controles internos e a melhoria da gestão de riscos da empresa, indicadores relevantes na avaliação da qualidade do serviço de auditoria interna. A pesquisa revelou uma considerável divergência perceptiva entre auditores e auditados no que tange à avaliação do comportamento dos auditados, que possuem uma percepção mais positiva sobre esse aspecto em comparação com os auditores. A percepção do uso de boas práticas de auditoria interna por auditores e auditados está, na maioria dos casos, coerente com os atributos de qualidade citados na literatura, indicando a presença desses atributos na avaliação da qualidade do serviço de auditoria interna.

  9. Bilateral talipes equinovarus from Tikal, Guatemala.

    Science.gov (United States)

    Wright, Lori E

    2011-03-01

    An incomplete skeleton recovered from a multiple, secondary burial at Tikal, Guatemala, shows malformed foot bones consistent with a diagnosis of bilateral idiopathic talipes equinovarus. Bones attributable to the skeleton include paired bowed fibulae, fragmentary calcanei, complete tali, naviculars, cuneiforms, metatarsals, and some phalanges. The tali are reduced in size, flattened, and hyperextended, with the tibia partially articulated on the calcaneus, posterior to the talus. The cuboid and cuneiforms show marked contraction of the inferior surfaces, and angulation. The metatarsals and phalanges present minor changes to the articulations, and slender shafts. Articulated, both feet show marked equinovarus deformity, with weight carried on the lateral margin and superior surface of the feet. Key conditions considered in the differential diagnosis are those producing an equinovarus or a calcaneocavovarus deformation, especially progressive neuromuscular disorders. This paper describes the nature of the bony changes, reconstructs the morphology of the feet, and offers a differential diagnosis. Scholars of the ancient Maya have identified artwork that appears to depict talipes equinovarus, although there was no osteological evidence for the condition among the Maya prior to the diagnosis of this case.

  10. Prophylactic bilateral mastectomy for breast cancer prevention.

    Science.gov (United States)

    Metcalfe, Kelly A

    2004-09-01

    Prophylactic bilateral mastectomy, or preventive removal of the breasts, is an option for women who are at increased risk of developing breast cancer. Among the highest risk groups are those women with a significant family history of breast cancer and those with a known genetic predisposition to the disease. There are many issues surrounding prophylactic mastectomy. Recent research has demonstrated that prophylactic mastectomy may be effective in preventing breast cancer in high-risk women, as well as those with a known BRCA1/2 mutation. The limited research that has been done on the psychosocial implications of the preventive surgery suggests that prophylactic mastectomy may be effective in reducing distress levels in high-risk women and that most women who have had the surgery do not experience psychosocial difficulties. Overall, women who have had prophylactic mastectomy are satisfied with their decision to have the preventive surgery. However, women who choose prophylactic mastectomy may differ compared with those who do not. The results may not be generalizable to all high-risk women. Counseling of high-risk women, specifically those with a BRCA1 or BRCA2 mutation, should include a discussion of prophylactic mastectomy, including the medical and psychosocial risks and benefits.

  11. Bilateral Psoas Haematomata Complicating Renal Transplantation

    2014-01-01

    Full Text Available Background. The challenge in managing patients undergoing renal transplantation is how to achieve optimum levels of anticoagulation to avoid both clotting and postoperative bleeding. We report a rare case of severe postoperative retroperitoneal bleeding including psoas haematomata complicating renal transplantation. Case Report. SM, a 55-year-old female, had a past history of aortic valve replacement, cerebrovascular event, and thoracic aortic aneurysm and was on long-term warfarin that was switched to enoxaparin 60 mg daily a week prior to her living donor transplantation. Postoperatively, she was started on a heparin infusion, but this was complicated by a large retroperitoneal bleed requiring surgical evacuation on the first postoperative day. Four weeks later, she developed features compatible with acute femoral neuropathy and a CT scan revealed bilateral psoas haematomata. Following conservative management, she made steady progress and was discharged home via a community hospital 94 days after transplantation. At her last visit 18 months after transplantation, she had returned to full fitness with excellent transplant function. Conclusion. Patients in established renal failure who require significant anticoagulation are at increased risk of bleeding that may involve prolonged hospitalisation and more protracted recovery and patients should be carefully counselled about this.

    2011-04-01

    In 2010, the Office for Science and Technology of the French Embassy in Washington DC provided seed funding to enable a new scientific collaboration between the US and France. The work primarily focuses on the understanding of the interaction of particles with the DNA. The National Society of Black Physicists managed the funds. This so-called G4TRAP work is an extension of the ESA-funded G4DNA project that uses the Geant4 Monte Carlo toolkit and is spearheaded by the University of Bordeaux 1 in France. This initiative spawns to new areas (ultrafast lasers, nuclear/high energy physics, radiation biology and space science) and includes US industries, thanks to the interdisciplinary activities needed to advance this project. In addition, the bi-lateral collaboration was expanded to two other countries: Canada and Senegal. Subsequent funding requests were made to US agencies (NSF and DoE) as well as other French programs. More are anticipated that will also include NIH, NASA and the Canadian programs. A review of this multidisciplinary effort will be presented along with the present status on the various aspects of the G4TRAP project.

  13. Bilateral maculopathy following electrical burn: case report

    Directory of Open Access Journals (Sweden)

    Leandro Dario Faustino

    Full Text Available CONTEXT: Electrical burns are an important etiology in dealing with patients suffering from burns. In situations of extensive deep lesions of multiple organs and systems affecting young and economically active people, there is a need for expensive multidisciplinary treatment, with a high socioeconomic cost for the community. Among the permanent injuries that explain this high cost, eye injuries stand out, since they are widely disabling. Although rare, lesions of the posterior segment of the eye are associated with higher incidence of major sequelae, and thus deserve special attention for dissemination and discussion of the few cases observed.CASE REPORT: The authors report the case of a patient who suffered high-voltage electrical burns and presented bilateral maculopathy, which evolved with a need for a surgical approach to repair retinal detachment and permanent low visual acuity.CONCLUSION: This report highlights the rarity of the etiology of maculopathy and the need for campaigns for prevention not only of burns in general, but also especially of electrical burns.

    Dislocation of the tibiofibular joint is rare and usually results from a traumatic event. Only 1 case of atraumatic proximal tibiofibular joint instability in a 14-year-old girl has been reported in the literature, however this condition might occur more frequently than once thought. A wide range of treatment options exist for tibiofibular dislocations. Currently, the first choice is a conservative approach, and when this fails, surgical means such as resection of the fibula head, arthrodesis, and reconstruction are considered. However, no consensus exists on the most effective treatment. This article reports a unique case of bilateral, atraumatic, proximal tibia and fibular joint instability involving a 30-year-old man with a 20-year history of pain and laxity in the right knee. The patient had no trauma to his knees; he reported 2 immediate family members with similar complaints, which suggests that this case is likely congenital. After conservative approaches proved to be ineffective, the patient underwent capsular reconstruction using free autologous gracilis tendon. At 6-month postoperative follow-up, the patient was pain free with no locking and instability. He then underwent surgery on the left knee. At 1-year follow-up after the second surgery, the patient had no symptoms or restrictions in mobility. We provide an alternative surgical approach to arthrodesis and resection for the treatment of chronic proximal tibiofibular instability. In the treatment of chronic tibiofibular instability, we believe that reconstruction of the tibiofibular joint is a safe and effective choice. Copyright 2011, SLACK Incorporated.

    Complete open surgical resection is the standard treatment for thymoma and myasthenia gravis. We evaluated the feasibility of bilateral video-assisted thoracoscopic extended thymectomy, and compared it to surgery via sternotomy. From 2011 to 2014, 43 patients undergoing thymectomy were divided into 2 groups: 23 underwent video-assisted thoracoscopic extended thymectomy, and 20 had thymectomy via sternotomy. The primary outcomes were postoperative pain score (visual analog scale) at 6, 12, 24, 48, and 72 h, and 1-month postoperatively, and morphine consumption in the first 48 h. Secondary outcomes were surgical and clinical results. There were no significant differences between the 2 groups in terms of demographics and preoperative clinical data. Compared to the sternotomy group, the video-assisted thoracoscopic thymectomy group had lower pain scores and morphine consumption at all time points, significantly less operative blood loss and chest drainage volume, and shorter hospital stay. The rates of improvement in myasthenia gravis were 85% and 86% in the video-assisted thoracoscopic thymectomy and sternotomy groups, respectively. No recurrence of thymoma was found in either group (median follow-up 27 months). Our results seem to confirm that in selected cases, video-assisted thoracoscopic thymectomy allows complete resection of thymus and perithymic tissue, similar to sternotomy but with the known advantages of minimally invasive surgery including less pain and a good cosmetic result. © The Author(s) 2016.

    En esta tesis presento una metodología de seleccion y estudio de la población estelar embebida en la nube molecular galactica asociada a la fuente IRAS 18236-1205. La fuente IRAS posee colores de region Ultra Compacta HII (UCHII) y tiene deteccióon en monosulfuro de carbono (CS), trazador molecular de alta densidad, lo cual da la posibilidad de definir la nube molecular asociada hacia esta region. Lo anterior muestra que esta es buena candidata a región de formación estelar masiva. La metodología de seleccion de la población embebida, est à basada por una parte, en la distribución del gas molecular monoxido de carbono (13CO) asociado a la fuente IRAS, nube molecular seleccionada del mapeo Galactic Ring Survey (GRS) realizado en 13CO. Otros pasos de la seleccion, se basan en los diagramas color-color y color-magnitud con datos del cercano infrarrrojo de 2MASS. Para el estudio de la componente estelar se usaron los catalogos de fuentes puntuales en el cercano, medio y lejano infrarrojo de 2MASS, SPITZER e IRAS, respectivamente. De los diagramas color-color y color-magnitud, usando datos de 2MASS, se construyo un criterio fotométrico para identificar los objetos estelares j ovenes embebidos en la region molecular. Aplicando modelos a la distribución espectral de energía (SED) de algunos ellos, se encontraron parametros estelares de objetos estelares j ovenes embebidos de masa intermedia y alta. Adicionalmente, se encontro un objeto de masa ´ intermedia no identifiado por el catalogo de 2MASS y su efecto sobre el medio interestelar, emision en la banda de [4.5] μm de IRAC-Spitzer asociado a un outflow. Dos de los objetos seleccionados por el criterio fotometrico resultaron ser objetos estelares jovenes de alta e intermedia masa (B1V/B2V y B8V/A0V respectivamente), los cuales deben estar asociados a la emision radiativa responsable de los colores de región UC HII. Otro objeto estelar joven de baja masa (F0V/F5V) fue encontrado en la region de estudio

    The optimal treatment for bilateral hearing loss continues to evolve as cochlear implant (CI) and hearing aid technologies advance, as does our understanding of the central auditory system. Ongoing discussions continue on the validity and feasibility of bilateral CI in terms of performance, justification of need, medical/surgical safety concerns, and economics. The purpose of this review article is to provide an update on the advantages and disadvantages of bilateral CI and to provide a discussion on timing (simultaneous vs. sequential), technology (bimodal vs. binaural) and feasibility. Binaural advantages are found in both adult and pediatric bilateral CI recipients, the greatest being the head shadow effect and improvements in localization and loudness summation. This theoretically offers an advantage over their unilateral implanted counterparts in terms of improved sound localization and enhanced speech perception under noisy conditions. Most investigators agree that bilateral stimulation during critical periods of development is paramount for optimizing auditory functioning in children. Currently, bilateral CI is widely accepted as a safe and effective means of bilateral auditory stimulation.

    Full Text Available Orbital involvement in systemic sarcoidosis is a rare condition. We report a case of orbital sarcoidosis with bilaterally huge lacrimal gland involvement as the initial manifestation of systemic sarcoidosis. A 20-year-old woman admitted the ophthalmology department with progressive bilateral upper eyelid swelling for 6 months. The only pathologic finding was the presence of bilateral, symmetrical, solid, lobular masses at the lateral upper eyelids at the location of lacrimal glands. On systemic examination, bilateral parotid and submandibular glands appeared swollen. Magnetic resonance imaging of the orbit revealed bilateral symmetrical diffuse enlargement of the lacrimal glands with maximum and minimum thickness of 11 mm and 7 mm, respectively. The biopsy findings were compatible with sarcoidosis. Although lacrimal gland involvement has been reported in different studies, we for the first time report an unusual case with bilateral diffuse huge lacrimal gland involvement. Normal lacrimal gland thickness is approximately 4-5 mm in magnetic resonance imaging, while our case had bilateral diffuse enlargement of lacrimal glands, which showed maximum and minimum thickness of 11 mm and 7 mm, respectively. Although orbital involvement is uncommon in sarcoidosis, it should be remembered in the differential diagnosis of orbital masses.

    Full Text Available We reported a case of cryptococcal meningitis presenting with bilateral optic neuropathy in an immunocompetent patient. A 64-year-old Malay gentleman with no medical comorbidities presented with acute bilateral blurring of vision for a week, which was associated with generalised throbbing headache and low grade fever. He also had somnolence and altered consciousness. Visual acuity in both eyes was no perception of light with poor pupillary reflexes. Extraocular muscle movements were normal. Anterior segments were unremarkable bilaterally. Fundoscopy revealed bilateral optic disc swelling. CT scan of the brain showed multifocal infarct, but no meningeal enhancement or mass. Cerebrospinal fluid opening pressure was normal, while its culture grew Cryptococcus neoformans. A diagnosis of cryptococcal meningitis with bilateral optic neuropathy was made. Patient was treated with a six-week course of intravenous fluconazole and started concomitantly on a fortnight's course of intravenous amphotericin B. After that, his general condition improved, but there was still no improvement in his visual acuity. On reviewing at two months post-initiation of treatment, fundi showed bilateral optic atrophy. Bilateral optic neuropathy secondary to cryptococcal meningitis was rare. The prognosis was guarded due to the sequelae of optic atrophy. Anti-fungal medication alone may not be sufficient to manage this condition. However, evidence for other treatment modalities is still lacking and further clinical studies are required.

    Full Text Available 1989 supuso para Argentina la llegada a la presidencia del justicialista Carlos Menem y el inicio de un sorprendente giro, dados los antecedentes de su partido, hacia políticas neoliberales. Como paso previo, sin embargo, Menem debió vencer en unas elecciones internas en las que partía, en principio, en clara desventaja ante el favorito Antonio Cafiero, gobernador de la provincia de Buenos Aires y líder de la llamada Renovación peronista. La sorprendente victoria de Menem en 1988 ha sido explicada comúnmente como fruto de la reacción de la sociedad a la clase política, en el contexto de crisis que atravesaba el país, o bien como producto de los límites e insuficiencias de la línea cafierista. Sin desconocer estos enfoques, en este texto abordamos el problema desde la perspectiva interna del peronismo y del propio Menem, describiendo su labor de acumulación y reestructuración de los sectores más ortodoxos del partido, apartados por el avance de la Renovación. El estudio de estas elecciones internas sirve así para explorar las continuidades y rupturas de la Argentina que abre un nuevo ciclo en 1989.Palabras clave: Argentina, peronismo, Menem, Renovación, elecciones, 1988___________________________ABSTRACT:1989 marked the arrival to the Argentinian presidency of the PJ Carlos Menem and the beginning of a surprising twist, considering the history of his party, towards neoliberal policies.

Menem's stunning victory in 1988 has been commonly explained as the result of society's reaction to the political class, in the context of crisis of the country, or as a result of the limits and shortcomings of the Cafiero’s political line.

    Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: In order to achieve its long-term emission reduction target following the Fukushima incident, Japan would rely more heavily on international offsetting activities. Concurrent to vigorous proposals to reform the CDM, Japan is also promoting an offset crediting scheme through bilateral agreements with developing countries as a post-2012 market mechanism. Despite potential benefits, issues relating to the accounting rules, environmental integrity and implications to carbon markets warrant further consideration prior to international recognition

    Full Text Available Bilateral cortisol-secreting adenomas are a rare cause of Cushing's syndrome. We report a case of a 35-year-old woman who presented with ACTH-independent Cushing's syndrome and bilateral adrenal adenomas. Adrenal venous sampling confirmed both adenomas to be hyper-secreting cortisol. She underwent bilateral laparoscopic adrenalectomy; total right and partial left adrenalectomies. At 2-year follow-up, she is maintained on low-dose fludrocortisone and hydrocortisone, and without recurrence of hypercorticolism. Laparoscopic partial adrenalectomy is a feasible option for this rare condition; however, long-term follow-up is needed to determine her total independence from steroid usage.

    Full Text Available The aim of this work is the integration of a virtual environment containing a deformable object, manipulated by an open kinematical chain virtual slave robot, to a bilateral teleoperation scheme based on a real haptic device. The virtual environment of this hybrid bilateral teleoperation system combines collision detection algorithms, dynamical, kinematical and geometrical models with a position–position and/or force–position bilateral control algorithm, to produce on the operator side the reflected forces corresponding to the virtual mechanical interactions, through a haptic device. Contact teleoperation task over the virtual environment with a flexible object is implemented and analysed.

    Full Text Available Maisonneuve fractures result from a disruption of the medial ankle structures and a proximal fibular fracture. Patient complaints can be misleading and there is a significant rate of delayed diagnosed injuries. We present a case of bilateral Maisonneuve fractures after a fall due to a syncopal collapse. A precise clinical examination led to this rare diagnosis. The injuries were treated with syndesmotic screw fixation, removal of hardware followed after 6 weeks. The patient was asymptomatic at threemonths follow up. Patients with bilateral injuries undergoing standard surgical treatment can gain full recovery, but high suspicion in clinical examination is needed to detect this uncommon bilateral injury.

    A six-month-old baby with congenital patent ductus arteriosus (PDA), bilateral microtia and canal atresia was referred for hearing assessment. The audiology assessment revealed bilateral profound hearing loss, which is atypical for a case of pure canal atresia. Imaging was performed much earlier than usual and, as suspected, the patient also had bilateral severe inner ear anomaly. It is extremely rare for a person to have both external and inner ear anomaly because of the different embryological origin. The only suitable hearing rehabilitation option for this kind of patients is brainstem implant. However, the parents had opted for sign language as a form of communication.

    2017-04-01

    Asymmetry of the human axial skeleton has received much less attention that of the limb skeleton. Pelvic morphology is subject to multiple selective factors, including bipedal locomotion and obstetrics, among others, as well as environmental factors such as biomechanical loading. How these various factors influence or restrict asymmetry of the pelvis is unknown and few studies have investigated levels and patterns of pelvic asymmetry. This study examines percentage directional (%DA) and absolute (%AA) asymmetry in 14 bilaterally paired dimensions of the pelvic canal, non-canal pelvis, and femur in female (n = 111) and male (n = 126) skeletons from nine geographically dispersed skeletal samples. Directional asymmetries were uniformly low for all measures and lacked any consistent patterning across the variables, while %AA was highest in the pelvic canal, particularly the posterior aspects. Few sex differences and no population differences were found for %DA and %AA; however the latter was correlated with coefficients of variation across the 14 variables in both sexes. While sample mean %DA were low, standard deviations of the canal variables were high and the majority of individuals in both sexes displayed %DA values >±0.5, suggesting asymmetry is common, if not directionally consistent. Biomechanical loading of the pelvic girdle may influence asymmetry of both the canal and non-canal aspects of the pelvis; however it is unlikely that these asymmetries negatively affect obstetric function, given the prevalence for %DA found in this study.

    Retrospective case series, database study and literature review. Forty case reports are described. To report a possible association between fluoroquinolones and uveitis. Spontaneous reports from the National Registry of Drug-Induced Ocular Side effects, World Health Organization, and Food and Drug Administration were collected on uveitis associated with systemic fluoroquinolone therapy. A literature review was performed using keywords "uveitis", "fluoroquinolones", and each individual fluoroquinolone name. Additional case reports were collected from the practices of six uveitis subspecialists and one neuro-ophthalmologist. Data garnered from the reports include the type of fluoroquinolone, age, gender, adverse drug reaction (ADR), dosage, duration of therapy until onset of uveitis, concomitant drugs, systemic disease, dechallenge and rechallenge data. A total of 40 case reports of uveitis associated with fluoroquinolones were identified including 12 men, 27 women, and 1 case in which the gender was not specified. The median age was 54 years. Dosage varied between the different fluoroquinolone drugs, with the median dosage within the range recommended in the package insert for each different fluoroquinolone. Median time from beginning of therapy to appearance of the ADR was 13 days (range 0-20 days). Thirteen patients were 60 years or older, and one patient was taking systemic anti-inflammatory steroids. There were five positive dechallenge case reports. According to World Health Organization criteria, the relationship between fluoroquinolone therapy and uveitis is "possible". Causality assessments are based on the time relationship of drug administration, uveitis development, and dechallenge data. Clinicians should be aware of a possible bilateral fluoroquinolone-associated uveitis, particularly the finding of iris transillumination and pigment dispersion.

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.

    Full Text Available A anatomia e a morfologia interna do tronco encefálico (TE do macaco-prego (Cebus apella foram descritas com base nas observações feitas em troncos encefálicos de macacos adultos. Seis macacos Cebus apella adultos foram utilizados para as observações anatômicas. Para os estudos da morfologia interna os TE foram cortados seriadamente em seis níveis diferentes: decussação piramidal, porção superior da oliva, porção inferior da oliva, ponte, colículo superior e colículo inferior. Após esse procedimento eles foram corados com a técnica de Mulligan modificada por nós. Nossos resultados mostram que o TE de Cebus apella é caracterizado pela presença do sulco bulbo-pontino, aumento do tamanho do TE, especialmente da medula oblonga, com consequente lateralização do corpo trapezoide, presença do sulco ântero-lateral separando as pirâmides das olivas; desenvolvimento expressivo do corpo trapezoide, da ponte, dos núcleos da ponte e do pedúnculo cerebral. Estes resultados são consistentes com descrições prévias para outros primatas na literatura e sugerem que a organização e desenvolvimento do TE exibe semelhanças com primatas superiores, incluindo o homem, o que reflete as habilidades motoras da espécie estudada.
