    Objective: To describe the high-resolution computed tomography findings in the lung of patients with systemic sclerosis, independently of the respiratory symptoms. Materials and methods: Seventy-three high-resolution computed tomography scans of 44 patients with clinical diagnosis of systemic sclerosis were reviewed and defined by the consensus of two radiologists. Results: Abnormalities were seen in 91.8% (n = 67) of the scans. The most frequent findings were reticular pattern (90.4%), ground-glass opacities (63%), traction bronchiectasis and bronchiolectasis (56.2%), esophageal dilatation (46.6%), honeycombing pattern (28.8%) and signs of pulmonary hypertension (15.6%). In most cases the lesions were bilateral (89%) and symmetrical (58.5%). The lesions were predominantly located in the basal (91.2%) and peripheral (92.2%) regions. Conclusion: In the majority of the patients, progressive systemic sclerosis can cause pulmonary fibrosis mainly characterized by reticular pattern with basal and peripheral distribution on high-resolution computed tomography.

    Full Text Available A silicose é a pneumoconiose mais frequente, decorrente da inalação de sílica ou de poeiras minerais contendo silicatos, caracterizada principalmente pela fibrose pulmonar de caráter irreversível. Está associada com o desenvolvimento de outras doenças, incluindo tuberculose pulmonar, câncer pulmonar e doenças autoimunes. A doença do tecido conjuntivo posterior à exposição à sílica ocorre geralmente após 15 anos do início da exposição. A síndrome de Erasmus refere-se ao desenvolvimento de esclerose sistêmica em indivíduos previamente expostos à sílica e que apresentavam ou não silicose. Os autores relatam dois casos de pacientes com diagnóstico de silicose que desenvolveram esclerose sistêmica.

    Full Text Available We report a case of a 44-years-old woman with relapsing-remitting and secondarily progressive form of multiple sclerosis (MS since aged 24 years, who developed an anaplastic astrocytoma. The neurological manifestations of the tumor were misinterpreted as resulting from MS. Sequential MRI examination and seizures raised the possibility of another nature of her symptoms, besides MS. Her initial good response to high doses corticosteroids led to the initial assumption her symptoms were only exclusively due to the demyelinating process. She underwent craniotomy with radical excision of the lesion. Pathological examination disclosed anaplastic astrocytoma. Other cases of coincidental MS and primary CNS tumors are reviewed, as well as their possible relation.Relatamos o caso de uma paciente de 44 anos, portadora de esclerose múltipla forma surto-remissão e progressiva secundária, que na evolução desenvolveu um astrocitoma anaplásico. Os sintomas do tumor se confundiram com os da esclerose múltipla e com a repetição de ressonâncias magnéticas foi possível suspeitar do diagnóstico. Além dos sinais neurológicos, também apresentava crises convulsivas. A melhora com os cursos de pulsoterapia mascaravam os sintomas do tumor. Submetida a craniotomia e retirado tumor com características histológicas e histoquímicas de astrocitoma anaplásico, ao lado de áreas de desmielinização típicas de esclerose múltipla. São discutidos os aspectos radiológicos, incidência e mecanismos da concomitância das duas doenças.

    Full Text Available A esclerose múltipla é uma afecção neurológica que envolve distúrbios da deglutição. Muitos estudos têm mostrado associação entre o comprometimento neurológico e o desempenho da deglutição, porém, os resultados têm sido conflitantes. OBJETIVO: Identificar a frequência de disfagia nos pacientes com esclerose múltipla e os indicadores neurológicos que podem representar o desempenho da deglutição. MÉTODO: Neste estudo (estudo transversal, 120 pacientes com esclerose múltipla foram submetidos à avaliação funcional da deglutição por fibronasofaringolaringoscopia, cujos resultados foram comparados com a pontuação das escalas de classificação (Formas Clínicas Evolutivas da Doença, Escala de Incapacidade Funcional por Sistemas e Escala Ampliada de Incapacidade Funcional [Kurtzke Expanded Disability Status Scale]. RESULTADOS: A disfagia foi identificada em 90% dos pacientes. Dentre as formas clínicas, as formas progressivas (primária progressiva e secundária progressiva apresentaram com maior frequência disfagia grave, enquanto a forma remitente-recorrente apresentou mais frequentemente disfagia leve e moderada. Em relação à Escala de Incapacidade Funcional por Sistemas, as funções cerebelares, do tronco encefálico e mental tiveram associação com a disfagia, especialmente na forma grave. Quanto à Escala Ampliada de Incapacidade Funcional, pontuações mais altas se associaram aos quadros graves de disfagia. CONCLUSÃO: A disfagia é frequente em pacientes com esclerose múltipla, especialmente naqueles com maior comprometimento das funções neurológicas.

    Full Text Available Esclerose múltipla é doença que apresenta índice de baixa prevalência no Brasil. No entanto, a doença é similar àquela observada em outras regiões do globo, onde a doença é mais comum. São apresentados 50 casos de esclerose múltipla, classificados de acordo com os critérios internacionais. A série estudada apresenta características epidemiológicas semelhantes às séries internacionais, em que se observa acometimento maior de adultos jovens do sexo feminino, preferencialmente. Os sinais e sintomas mais comuns foram piramidais e cerebelares, sendo pouco frequente o acometimento visual. A forma clínica mais comum foi surto-remissiva. O número de surtos, o tempo de evolução da doença, o tipo de comprometimento piramidal e a presença de sinais cerebelares no início do quadro foram os fatores determinantes da incapacidade funcional dos pacientes, refletida por valores mais altos de EDSS. A ressonância magnética de crânio, realizada em 22 pacientes mostrou alterações de substância branca, compatível com doença desmielinizante. Não foi observada relação entre o quadro clínico e o grau de comprometimento evidenciado pelo exame.

The use of this technique may help (reconstruction personal identities and improve quality of life of patients with multiple sclerosis (MS. Eight adult patients on treatment at CIEM Multiple Sclerosis Investigation Center after selecting 10 to 15 pieces of music most significant in their lives were interviewed. The data collected were classified according to Even Rudd categories, which reveal how a person expresses his personal, social, temporal and transpersonal identities. We observed that recall of musical history makes MS patients get better perception both of their feelings and body awareness, as well as provide them with an alternative way to express themselves, activate and contextualize affective memories, and achieving a sense of life continuity in spite of the disease.Autobiografias musicais constituem um recurso terapêutico pelo qual indivíduos definem a si mesmos, auxiliando a (reconstrução da identidade e contribuindo para a melhora da qualidade de vida de portadores de esclerose múltipla (EM. Oito pacientes adultos sob acompanhamento no Centro de Investigação em esclerose múltipla (CIEM da UFMG, selecionaram entre 10 e 15 músicas significativas em sua vida, a respeito das quais discorreram em entrevista aberta. Os dados foram analisados qualitativamente segundo categorias criadas por Even Rudd, que visam revelar como o indivíduo expressa suas identidades pessoal, social, temporal e transpessoal. Submetidos a tratamento quantitativo, os dados demonstraram que, através da sua história musical, os pacientes aumentaram a percepção dos sentimentos e sensações corporais, expressaram-se de maneiras alternativas e ativaram memórias afetivas, contextualizando-as e adquirindo um senso de continuidade da vida.

    Full Text Available A natureza crônica e progressivamente incapacitante de muitas enfermidades neurológicas, tais como a esclerose múltipla, constitui um desafio para a reabilitação. Uma abordagem que objetive apenas a restituição funcional corre o risco de fracassar, impondo uma carga de sofrimento adicional ao portador. As abordagens compensatórias têm se demonstrado eficazes no intuito de capacitar os portadores de doenças crônicas a enfrentar suas dificuldades cotidianas a curto-prazo e planejar o seu curso de vida a longo-prazo, aumentando assim o senso de controle e autonomia e melhorando a qualidade de vida. A abordagem compensatória impõe o estabelecimento de uma agenda positiva. Neste ensaio nós estabelecemos um paralelo entre a adaptação psicossocial à esclerose múltipla e os processos observados no desenvolvimento psicológico adulto. São notadas tanto semelhanças quanto diferenças. Algumas possibilidades são exploradas, que os modelos derivados do estudo do desenvolvimento bem-sucedido na idade adulta e velhice oferecem para o estabelecimento de uma agenda positiva para os portadores de esclerose múltipla.The chronic and progressively incapacitating nature of many neurological illnesses, such as multiple sclerosis, poses major challenges to the rehabilitative efforts. Approaches based solely on the pursuit of functional restitution incur the risk of failure and additional distress to the sufferers. Compensatory approaches have been consistently shown effective in the empowerment of individuals both to cope with daily life in the short run and to plan their life courses in the long run, thus regaining control and autonomy and improving well being. Compensation requires the establishment of a positive agenda. In this essay we establish a parallel between the processes of psychosocial adaptation to multiple sclerosis and normal adult development. Both similarities and differences are noted. We try to explore some perspectives derived

    Full Text Available Introdução: O Complexo de Esclerose Tuberosa (CET é uma síndrome neurocutânea transmitida hereditariamente, de traço autossômico dominante e que se manifesta por uma tríade clássica: deficiência mental, convulsões e adenoma sebáceo. A mutação responsável pela síndrome está presente em até 85% dos portadores de CET e.ocorre nos genes supressores tumorais TSC1 e TSC2, que produzem hamartina e tuberina, respectivamente.A prevalência do CET é de 1:10.000 a 1:170.000, atinge mais indivíduos do sexo masculina e é rara em negros. Relato de Caso: R.C.S.B., paciente do sexo feminino, 16 anos, vem encaminhada ao ambulatório de neurologia devido a quadro de convulsões tônico-clônicas generalizadas e crises de ausência diárias há 1 ano, mas com história de convulsões aos 2 anos que cessaram espontaneamente. Está em tratamento com fenitoína 200mg/dia e carbamazepina 800mg/dia, mas ainda apresenta crises de ausência. A paciente apresenta as lesões cutâneas típicas do CET: adenomas sebáceos (angiofibroma em face distribuídos simetricamente entre nariz e bochechas, envolvendo ainda fronte e queixo. Não há sinais de retardo mental. A ressonância nuclear magnética revelou imagens com padrão compatível com áreas de desmielinização. O eletroencefalograma encontrava-se normal. Conclusão: O tratamento do CET ainda é um desafio para muitos neurologistas, uma vez que não há tratamento específico para doença. A paciente deve contar com equipe multidisciplinar, por vezes é necessário acompanhamento com neurologista, dermatologista, geneticista, psicólogos e outros, dependendo das manifestações do CET. A finalidade terapêutica é a qualidade de vida da paciente, que pode ser prejudicada pelas várias convulsões ou alterações estéticas da doença.

    Full Text Available RESUMO A Esclerose Sistêmica é uma doença reumática autoimune do tecido conjuntivo, progressiva, pouco frequente, de etiologia desconhecida e com evolução variável. Atinge órgãos nobres e tecidos periorais, causando limitação na abertura da boca, hipertonia dos órgãos fonoarticulatórios, face com "aparência de máscara", dificuldades na mastigação e deglutição. Com o objetivo de comparar os resultados pré e pós-intervenção fonoaudiológica miofuncional orofacial em sujeitos com esclerose sistêmica, realizou-se estudo clínico exploratório qualiquantitativo no setor de Reumatologia do Hospital Universitário e na Clínica escola de Fonoaudiologia da Universidade Federal de Sergipe, no período de julho/2012 a dezembro/2013. A amostra foi composta por cinco indivíduos, de ambos os gêneros, com faixa etária entre 24 e 60 anos e diagnóstico médico confirmado da referida afecção. Os indivíduos passaram por avaliação por meio do protocolo MBGR e 36 sessões de terapia fonoaudiológica (miofuncional e mioterápica. Ao término, os resultados iniciais e finais foram comparados a partir dos indicadores clínicos trabalhados. Diante da análise dos resultados obtidos, foram observadas melhoras em todos os aspectos trabalhados. A avaliação anterior à fonoterapia revelou restrição na abertura da boca em todos os indivíduos e os resultados finais apresentaram ganhos entre 5.3 e 14.2 mm de abertura (média: 9,26 mm. Com relação à tonicidade, mobilidade dos órgãos fonoarticulatórios e dormência orofacial, observaram-se melhoras e evidências de adequação das funções orais. Pode-se concluir que, apesar de alguns pacientes ainda apresentarem alterações, a reabilitação fonoaudiológica promoveu melhoras significativas no quadro clínico e qualidade de vida dos indivíduos do grupo de estudo.

    Full Text Available O potencial evocado visual por padrão reverso, obtido por padrões de 14' e 28', foi analisado retrospectivamente em 28 pacientes com diagnóstico de esclerose múltipla definida. Observamos respostas anormais em 27/28 (96,4% pacientes, em 31/36 (86% dos olhos considerados sintomáticos e em 16/20 (80% dos ollhos assintomáticos. Classificando os achados em cada olho segundo as respostas obtidas aos dois estímulos, observamos uma possível relação entre essa classificação e a gravidade de comprometimento visual pela doença. Detectamos em alguns olhos anormalidades isoladas do N75 e também de P100 apenas à estimulação de 28'. Dessa forma, a técnica empregada foi considerada sensível e pôde definir inclusive comprometimento visual subclínico. Entretanto, não teve sensibilidade absoluta para detectar anormalidades em alguns olhos sintomáticos. O tipo de resposta aos estímulos empregados pode sugerir o grau de extensão de envolvimento do sistema visual pela doença. Os achados mostram ainda o envolvimento irregular e predominante das fibras mais centrais da visão pela esclerose múltipla, e sugerem processadores neurais distintos e paralelos para as respostas aos dois padrões utilizados.The pattern reversal visual evoked potential with checks of 14' and 28' was restropectivelly studied in 28 patients with definite multiple sclerosis. We observed abnormal responses in 27/28 (96.4% patients, in 31/36 (86% of symptomatic eyes, and in 16/20 (80% of asymptomatic eyes. When we classified the abnormalities in each eye according to the findings obtained with each check, there was a correlation between the pattern of abnormalities and the severity of visual involvement. Occasionally there were isolated abnormalities of N75 or only in P100 obtained with 28' checks. In conclusion the methodology applied was very sensible in detecting abnormalities in visual pathway. We could classify the findings in each eye and correlate them with the

MATERIAL E MÉTODO: Estudamos um grupo-controle (n=15 de indivíduos normais e um grupo experimental (n=15 que foi composto por pacientes com diagnóstico de esclerose múltipla. Ambos os grupos foram submetidos ao exame de potencial evocado miogênico vestibular. Em cada orelha foram aplicados 200 estímulos na forma de cliques e repetidos por 2 ciclos consecutivos com objetivo de avaliar a reprodutibilidade. Os eletrodos ativos de superfície foram colocados no S‡superior do músculo esternocleidomastoideo e de referência na borda anterior da clavícula ipsilateral. Os indivíduos foram instruídos à rotação lateral da cabeça em direção contralateral à orelha estimulada. RESULTADOS: Obtivemos no potencial evocado miogênico vestibular respostas rápidas, reprodutíveis e bifásicas. A latência das ondas P1 e N2 e amplitude P1-N2 apresentaram um maior valor no grupo experimental quando comparada com o grupo-controle. Não observamos diferença significativa nas respostas das ondas P1 e N2 e amplitude P1-N2 quando comparamos as orelhas. Verificamos que os indivíduos com esclerose múltipla apresentaram ausência de respostas em 30% dos casos. Ao avaliarmos os indivíduos do grupo experimental com sintomas otoneurológicos e compararmos com os pacientes sem sintomas, observamos que a latência da onda P1, N2 e amplitude P1-N2 estiveram maiores nos casos sintomáticos. CONCLUSÃO: O potencial evocado miogênico vestibular foi considerado um bom método de auxílio diagnóstico da via vestíbulo-espinal nos casos de esclerose múltipla.AIM: To evaluate vestibular evoked myogenic potentials in patients with multiple sclerosis as method of diagnostic support.

    Full Text Available INTRODUÇÃO: Esclerose múltipla é uma doença desmielinizante idiopática, podendo acometer o nervo óptico com perda visual unilateral aguda que pode ser observada através do potencial visual evocado (PVE, definindo tal exame como de grande validade para o estudo pré-quiasmático das vias visuais na esclerose múltipla. OBJETIVO: Analisar os achados dos potenciais visuais evocados por reversão de padrões em pacientes com diagnóstico prévio de esclerose múltipla e sua comparação com a acuidade visual. MÉTODOS: Vinte e quatro pacientes com diagnóstico definido de esclerose múltipla foram submetidos ao PVE por reversão de padrões no período de outubro de 2001 a março de 2007. RESULTADOS: Na resposta do componente P100, nos estímulos de 15' e 1º, se observou que 19 olhos apresentaram resposta de latência até 115 ms em ambas as estimulações, coincidindo também em 6 olhos que apresentaram resposta de latência entre 116 a 135 ms, em 11 olhos que apresentaram resposta de latências superiores a 135 ms, e em 4 olhos que não apresentaram respostas às estimulações. Correlacionando a acuidade visual com a latência de P100 para 15', obtemos na correlação de Pearson r= 0,85 com p= 0,000000123, e para 1º, r= 0,87 com p= 0,0000000338. CONCLUSÃO: Aproximadamente 60,4% dos pacientes apresentaram anormalidades no PVE por padrões reversos. Contudo, a correlação entre a latência de P100 (15' e 1º e a acuidade visual foi estatisticamente significativa, assim sendo, quanto melhor a acuidade visual, melhor será sua resposta aos estímulos do PVE por reversão de padrões.INTRODUCTION: Multiple sclerosis is an idiopathic demyelinating disease that may affect the optic nerve leading to acute unilateral visual loss, which could be observed by means of evoked visual potential (VEP.

    Full Text Available Mesial temporal sclerosis is the main pathological substrate present in refractory temporal lobe epilepsy and its presence is often related to the occurrence of febrile seizures in infancy. There is an on-going discussion on the nature of mesial temporal sclerosis as it related to epilepsy: cause or consequence. A previously normal child developed hyperosmolar coma after abdominal surgery at the age of 6. Three months afterwards he developed simple and complex partial seizures with an increasing frequency and refractory to multiple mono-and polytherapic drug regimens. He was evaluated for surgery at the age of 13. Ictal and interictal recordings showed left temporal lobe abnormalities. Early CT scaning suggested left temporal atrophy. MRI showed mesial temporal sclerosis. Neuropsichological testing showed verbal memory deficits and he passed a left carotid artery amytal injection. He was submitted to a cortico-amygdalo-hippocampectomy and has been seizure-free since then. The clinical data obtained from this patient suggest that at least in this case mesial temporal sclerosis would be related to the cause of epilepsy and not resultant from repeated seizure activity.A esclerose mesial temporal é o principal substrato anatomo-patológico envolvido na epilepsia refratária do lobo temporal e está frequentemente associada à ocorrência de convulsões febris na infância. Persiste até o momento intensa discussão se a esclerose mesial seria causa ou consequência da síndrome epiléptica. Uma criança previamente normal, desenvolveu coma hiperosmolar após intercorrência em cirurgia abdominal aos 6 anos de idade. Após 3 meses iniciaram-se crises parciais simples e complexas em frequência ascendente e refratárias a múltiplos esquemas terapêuticos em mono- e politerapia. Ele realizou investigação pré-operatória para epilepsia aos 13 anos de idade. Registros eletrencefalográficos de superfície ictais e interictais mostraram anormalidades

    Full Text Available The association between multiple (MS sclerosis and cerebral gliomas has been sporadically reported in the literature, causing a long lasting discussion if these lesions occur coincidentally or if MS plaques may actually lead to the genesis of gliomas. We report a 36 year old man who developed a rapid onset of right side weakness and loss of vision, having established a diagnosis of MS which was confirmed by CSF analysis and MRI. Nine years later he developed progressive tetraparesis, leading initially to suspicion of illness relapse and a demyelinating plaque in the spinal cord. However, after MRI investigation, a spinal cord tumor was diagnosed. The patient underwent cervical spine laminotomy for microsurgical removal of the spinal cord tumor diagnosed as ependimoma. The neurological deficits improved significantly.A associação entre esclerose múltipla (EM e gliomas cerebrais foi relatada esporadicamente na literatura, levando a longa discussão quanto à possibilidade das placas de esclerose estarem envolvidas na etiologia dos gliomas ou dessas lesões ocorrerem coincidentemente. Relatamos um paciente de 36 anos que desenvolveu hemiparesia direita rapidamente progressiva e perda visual, sendo estabelecido o diagnóstico de EM após análise do LCR e imagens de RM de encéfalo. Após nove anos o paciente desenvolveu tetraparesia lentamente progressiva, levantando inicialmente a hipótese de atividade da doença e aparecimento de placa de EM na medula espinal. Contudo, após investigação com RM de coluna, um tumor medular foi diagnosticado. Foi então submetido a laminectomia cervical para ressecção microcirúrgica do tumor, que foi diagnosticado como ependimoma. Os déficits neurológicos melhoraram significativamente.

All HAM/TSP and multiple sclerosis cases had an intrathecal immune response (oligoclonal IgG. In HAM/TSP, only 1/17 case showed a polyspecific intrathecal immune response against measles and rubella virus. In multiple sclerosis, specific antibodies against measles and rubella (MRZ response were observed in all patients but not in the control with idiopathic epilepsy. The diagnostic and theoretical relevance of mono- and polyspecific immune responses is discussed for these chronic neurological diseases.Amostras de líquido cefalorraquidiano (LCR e soro de 17 pacientes brasileiros com HAM/TSP, seis com esclerose múltipla e seis com epilepsia idiopática (controle não-inflamatório foram analisadas para a presença de anticorpos para os vírus do sarampo, rubéola, varicela zoster e herpes simples pelo método de ELISA. Todos os casos de HAM/TSP e esclerose múltipla tinham resposta imune intratecal (IgG oligoclonal.

    Full Text Available A Esclerose Sistêmica (ES é uma doença autoimune de etiologia multifatorial, desencadeada pela combinação de fatores genéticos e ambientais. Sua variada expressão clínica resulta da complexa interação fisiopatogênica de três elementos principais: a vasculopatia proliferativa, a desregulação imunológica e a deposição e remodelamento anormais da matriz extracelular (MEC, da qual resulta a fibrose característica da doença. Eventos fisiopatogênicos precoces parecem ser a lesão endotelial e o desequilíbrio no reparo vascular, com a ativação de células endoteliais, do sistema imune e das plaquetas, com a liberação de múltiplos mediadores, como as citocinas proinflamatórias TH2 e os fatores de crescimento, desencadeando uma sequência de eventos simultâneos ou em cascata que envolve diversas vias de sinalização intracelular. O resultado mais importante desses eventos é a hiperativação dos fibroblastos, as principais células efetoras da fibrose, as quais passam a produzir grandes quantidades de constituintes da MEC e a secretar múltiplos fatores de crescimento e citocinas que perpetuam o processo. Neste artigo apresentamos uma revisão dos principais fatores potencialmente implicados na etiologia da ES e revisitamos os conhecimentos atuais sobre os mais importantes mecanismos envolvidos no desenvolvimento das lesões características da doença. O melhor entendimento desses mecanismos fisiopatogênicos possibilita identificar potenciais alvos terapêuticos, o que pode resultar em avanços no manejo dessa complexa e debilitante doença.

    Full Text Available A esclerose múltipla (EM é uma doença neurológica progressiva e incapacitante, cujos sintomas afetam o funcionamento motor, sensorial e psicológico. Diversas variáveis clínicas e psicossociais influenciam o perfil neuropsicológico na EM, que é extremamente heterogêneo. O objetivo principal do presente estudo foi investigar a possibilidade de estratificar estatisticamente portadores de EM e controles a partir das dimensões neurológica, sócio-demográfica e neuropsicológica de funcionamento. A partir desse objetivo, foi conduzido um procedimento de análise de conglomerados utilizando cinco instrumentos neuropsicológicos, selecionados dentre uma gama de nove medidas, de acordo com a acurácia diagnóstica. A amostra foi constituída por 45 pessoas saudáveis e 35 portadores de EM com características sócio-demográficas semelhantes. Os resultados indicaram uma solução ideal com quatro conglomerados a partir de duas dimensões, funcionamento "cognitivo" e "psicossocial", que representam aspectos independentes, porém não disjuntivos, do funcionamento neuropsicológico na EM.Multiple sclerosis (MS is a progressively disabling neurological disease which symptoms affect sensory, motor and psychological functioning. Several clinical neurological and psychological variables influence the neuropsychological profile in MS, which is extremely heterogeneous. The main objective of the present study was to investigate if it is possible to statistically stratify control subjects and MS patients from neurological, socio-demographic and neuropsychological dimensions. With this purpose we applied cluster analysis procedures to five neuropsychological instruments selected according to diagnostic accuracy from a pool of 9 neuropsychological tests. The sample was composed of 45 healthy controls and 35 MS patients with similar socio-demographic characteristics. The results indicated an ideal solution with 4 different clusters according to two

    Full Text Available A patogênese da esclerose sistêmica (ES é complexa e pouco conhecida. Há a participação de ativação imune, dano vascular e excessiva produção de matriz extracelular com deposição de colágeno estruturalmente normal. Fatores genéticos e ambientais contribuem para a expressão da doença nos pacientes. Dentre os fatores ambientais, diversos agentes químicos já foram associados à doença. Descrevemos o caso de uma adolescente de 16 anos, com história prévia de hepatite criptogênica e câncer de lábio, que desenvolveu quadro atípico e rapidamente progressivo de esclerose sistêmica. Inicialmente o quadro era compatível com esclerodermia em placas, porém rapidamente evoluiu para uma forma sistêmica com grave acometimento cardiopulmonar e óbito. Durante a investigação de possíveis fatores etiológicos que pudessem estar relacionados, foram encontrados níveis séricos extremamente elevados de oxiclordano, um agrotóxico organoclorado. Uma possível correlação entre a intoxicação por esse agente químico e o surgimento de ES foi aventada.The pathogenesis of systemic sclerosis (SS is complex and not completely understood. Autoimmune mechanisms, vascular damage, and excessive extracelular matrix with collagen deposition play a significant role. Genetic and environmental factors also are decisive to the disease expression. Among environmental factors many chemical agents have been associated with the development of SS. A 16-year-old white woman, with previous history of cryptogenic hepatitis and cancer of the lips, developed an atypical and rapidly progressive form of SS. Initial sclerodermatous plaques progressed to a systemic form with severe cardiopulmonary involvement and death. Diagnostic workup revealed extremely high blood levels of oxychlordane. A possible association of organochlorine intoxication and SS is proposed.

    Full Text Available The aim of the present research was to investigate cognitive pattern of patients with neuromyelitis optica (NMO and to compare it with multiple sclerosis (MS patients' performance. Methods: Fourteen NMO, 14 relapsing remitting multiple sclerosis (RRMS, and 14 healthy control patients participated in the investigation. Neuropsychological functions were evaluated with the Brief Repeatable Neuropsychological Battery for MS; Symbol Digit Modalities Test; Digit Span; and Semantic Fluency. Results: Fifty-seven percent of NMO patients and 42.85% of the MS ones had abnormal performance in at least two cognitive tests. The NMO Group showed abnormal performance in verbal fluency, verbal and visual memories, with greater attention deficits. NMO patients outperformed healthy control in the paced auditory serial addition test (PASAT. However, no difference was found between NMO and RRMS patients. Conclusions: The NMO Group showed more dysfunction in attention and verbal fluencies than in verbal and visual memories. When compared with the MS patients, a similar dysfunction pattern was found. O objetivo da presente pesquisa foi investigar o padrão cognitivo de pacientes com neuromielite óptica (NMO e compará-lo com o desempenho de pacientes com esclerose múltipla (EM. Métodos: Quatorze pacientes com NMO, 14 com esclerose múltipla recorrente remitente (EMRR e 14 participantes do Controle saudáveis participaram da presente investigação. As funções neuropsicológicas foram avaliadas com a Bateria Breve de Testes Neuropsicológicos de Rao, Teste Símbolo Digit e a Fluência Semântica. Resultados: Cinquenta e sete por cento dos pacientes com NMO e 42,85% daqueles com EM apresentaram desempenho anormal em pelo menos dois testes cognitivos. O Grupo NMO apresentarou desempenho anormal na fluência verbal e nas memórias visual e verbal, com maiores déficits de atenção. Pacientes com NMO superaram os controles saudáveis em PASAT.

A produção de autoanticorpos séricos para proteína básica da mielina (MBP, proteolipídeo PLP e sequência da glicoproteína de oligodendrócito MOG 92-106, foi determinada em 54 indivíduos saudáveis e 26 pacientes com EM expressando ou não o alelo de suscetibilidade HLA-DQB1*0602. Independentemente da expressão do alelo DQB1*0602, todos os pacientes apresentaram produção marcante (p< 0,0001 de autoanticorpos isotipo IgG para MBP e MOG 92-106, e do isotipo IgA para PLP e MOG 92-106. Os resultados sugerem que outros alelos HLA da classe II exerçam influência na suscetibilidade à EM e no reconhecimento imunológico dos antígenos encefalitogênicos, determinando o padrão de resposta autoimune e contribuindo na manutenção e/ou controle da inflamação no SNC.

    Full Text Available Em razão dos avanços no conhecimento da esclerose múltipla (EM, dos novos critérios diagnósticos e ensaios terapêuticos publicados, a atualização e expansão das diretrizes para orientação do neurologista brasileiro em relação ao tratamento da EM se tornam necessárias. O Consenso Expandido do BCTRIMS enfatiza a individualização do tratamento a critério do neurologista, e a necessidade de informação do paciente quanto aos potenciais benefícios e riscos das drogas, assim como do Consentimento Informado e compromisso de realização de controles periódicos. Na ausência de evidências científicas favorecendo uma determinada droga o médico deve considerar o custo diferencial dos imunomoduladores ao fazer sua opção terapêutica. As várias situações clínicas e os diferentes agentes modificadores da doença, assim como as outras intervenções terapêuticas de eficácia no tratamento são consideradas à luz das classes de evidências científicas e dos tipos de recomendação, aceitos pela comunidade científica internacional. O Consenso Expandido do BCTRIMS pode servir de modelo para outros países em desenvolvimento.

    Full Text Available Introdução: Estudos recentes mostram associação entre tireoidites autoimunes e esclerose sistêmica (ES, e sugerem que essa condição pode interferir no fenótipo da ES. Entretanto, esses estudos avaliam as tireoidites autoimunes como um todo e nenhum deles aborda especificamente a tireoidite de Hashimoto (TH na ES. Objetivo: Investigar a presença de TH em pacientes com ES e sua possível associação com as manifestações da doença. Casuística e métodos: Manifestações clínicas de hipotireoidismo, TSH, T4 livre e anticorpos antitireoidanos (anti-TPO, anti TBG e TRAb foram pesquisados em 56 pacientes com ES. Pacientes com ES e TH foram comparados com pacientes com ES sem tireoidite. Resultados: TH foi observada em 19,64% dos pacientes com ES. Não foi encontrada associação entre a TH e as diferentes formas de doença ou com o perfil de autoanticorpos. Da mesma forma, não houve diferença entre a média do escore de Rodnan modificado e entre a presença de fenômeno de Raynaud, cicatrizes estelares, necrose digital, miosite, artrite, sintomas sicca, dismotilidade esofágica ou crise renal esclerodérmica quando os grupos foram comparados. Por outro lado, pacientes com TH apresentaram maior frequência de hipertensão pulmonar quando comparados a pacientes sem TH (66,6% vs 22,5%; p = 0,016. Conclusões: Na amostra de ES estudada, a TH está associada a uma maior prevalência de hipertensão pulmonar. Estudos de seguimento a longo prazo, englobando um número maior de pacientes com ES e TH, são necessários para confirmar esses dados.

    Full Text Available RESUMO: A esclerose lateral amiotrófica (ELA é uma doença neuromuscular rapidamente progressiva que envolve todos os grupos musculares com excepção dos músculos extra-oculares e dos esfíncteres. A maior causa de morbilidade e mortalidade são as complicações respiratórias que surgem habitualmente numa fase tardia da história natural da doença. Num número reduzido de casos, a ELA tem como manifestação inicial a insuficiência respiratória aguda.Os autores apresentam 2 casos clínicos de doentes internados num Serviço de pneumologia, sem doença neuromuscular prévia conhecida, com o diagnóstico de insuficiência respiratória aguda de etiologia desconhecida e que se revelaram ser ELA.A análise dos casos discutidos, e dos que estão já publicados na literatura, sugere que o aparecimento de insuficiência respiratória aguda em doentes sem história prévia de patologia pulmonar e/ou cardíaca, especialmente na 5.ª e 6.ª décadas de vida, deve alertar para a ELA como hipótese diagnóstica.REV PORT PNEUMOL 2004; X (6: 499-504 ABSTRACT: Amyotrophic lateral sclerosis (ALS is a fast progressing neuromuscular disease that affects all but the extrinsic muscles of the eye and sphincters. The main cause of morbidity and mortality are the respiratory complications that usually start in a late stage of the disease’s natural history. In a small number of cases acute respiratory failure is the initial manifestation of the disease.The authors present 2 case studies admitted to a pulmonary department, without previously known neuromuscular disease, with the diagnosis of acute respiratory failure of unknown ethiology and that were later shown to be cases of ALS.Analysis of the cases presented here, and those already published in the literature, suggests that the occurrence of acute respiratory failure in patients without a previous history of pulmonary and

    Full Text Available Esclerose múltipla é uma doença inflamatória desmielinizante, com presumida origem autoimune, que afeta o sistema nervoso central. A principal modalidade terapêutica é baseada no uso de imunomoduladores, como o interferon beta, que são geralmente bem tolerados. As manifestações cutâneas secundárias ao interferon beta-1b são representadas, na maioria das vezes, por reações no local de sua aplicação subcutânea. Descrevemos o caso de uma paciente do sexo feminino que desenvolveu um quadro de erupção acneiforme pelo interferon beta-1b.Multiple sclerosis is an inflammatory demyelinating disease of presumed autoimmune origin that affects the central nervous system. The main form of therapy is based on the use of immunomodulators such as interferon beta, which are usually well tolerated. Skin manifestations resulting from treatment with interferon beta-1b consist principally of reactions at the site of subcutaneous application of the drug. The present case report describes a female patient who developed an acneiform eruption resulting from treatment with interferon beta-1b.

RESULTADOS: Baixa autoestima se mostrou correlacionada com fadiga (p=0,01, porém não relacionada a qualquer outra variável, como sexo, idade, EDSS, duração da EM, número se surtos, depressão e/ou ansiedade leves. CONCLUSÃO: Maior gravidade de fadiga na EM se correlaciona com baixa autoestima, sugerindo assim que esta queixa crônica que afeta tantos pacientes pode interferir com a maneira pela qual eles se vêem e se valorizam.

    Full Text Available A capilaroscopia periungueal é um exame não invasivo e extremamente útil para avaliação do componente morfológico da microcirculação. Permite o diagnóstico diferencial precoce entre indivíduos com fenômeno de Raynaud (FRy primário e secundário. Na esclerose sistêmica e síndromes correlatas ocorrem alterações capilaroscópicas facilmente distinguíveis do padrão encontrado em indivíduos normais, sendo caracterizadas pela presença de ectasia capilar e áreas de deleção vascular, além de diminuição difusa da quantidade de alças. Em razão de sua relevância diagnóstica, a familiarização do médico clínico e do reumatologista com a CPU é de fundamental importância.Nailfold capillaroscopy is a noninvasive method useful for the evaluation of microcirculation morphologic component. It allows an early differential diagnosis between subjects with primary Raynaud's phenomenon and patients with secondary Raynaud's phenomenon. In systemic sclerosis and sclerodermaspectrum syndromes there are capillaroscopic findings easily distinguished from the pattern of healthy controls, and characterized by the presence of enlarged loops, avascular areas and diffuse loss of capillaries. Because of their diagnostic relevance, the acquaintance of internists and rheumatologists with nailfold capillaroscopy is of utmost importance.

    Full Text Available O câncer de ovário é a terceira causa de morte entre as neoplasias malignas em mulheres e o cistoadenocarcinoma mucinoso é uma neoplasia maligna originária do epitélio ovariano e que pode adquirir grandes dimensões. Alguns estudos sugerem um aumento do risco de neoplasia em pacientes com esclerose sistêmica (ES, mas a associação com neoplasia de ovário, principalmente do subtipo mucinoso, não é comum. Os autores descrevem um caso de cistoadenocarcinoma mucinoso de ovário em uma mulher branca de 52 anos com diagnóstico de ES difusa há seis anos, tratada previamente com D-penicilamina e ciclofosfamida, que procurou o serviço médico com queixa de dor e aumento do volume abdominal há três meses. Ao exame físico apresentava facies esclerodérmica, membros superiores com diminuição da elasticidade e enxerto bitibial em membros inferiores; no abdome havia a presença de uma massa endurecida estendendo-se da região suprapúbica até o epigástrio. Foi realizada laparotomia exploradora onde se encontrou uma massa cística no ovário direito, com peso de 3.300 gramas. Em seguida procedeu-se exérese do tumor com histerectomia total e ooforectomia bilateral. O exame histológico confirmou tratar-se de um cistoadenocarcinoma mucinoso sem invasão de cápsula.Ovarian cancer is the third cause of death among malignant neoplasia in women, and the mucinous cystadenocarcinoma is a malignant neoplasia of the ovarian epithelium, which may achieve great dimensions. Some studies suggest an increased risk of neoplasia in patients with systemic sclerosis (SSc, but the association with ovarian neoplasia, specially the mucinous subtype, is rare. The authors describe a case of ovarian mucinous cystoadenocarcinoma in a 52 year-old Caucasian woman who had the diagnosis of SSc 6 years ago, previously treated with cyclophosphamide and D-penicillamine, who sought for a medical service complaining of pain and increase of abdominal volume during the last

O envolvimento pulmonar é freqüente na ES; entretanto, hipertensão pulmonar (HP na ausência de fibrose intersticial é raramente observada. Os autores descrevem um caso de ES difusa com HP isolada em paciente do sexo feminino, de 49 anos. O diagnóstico de HP pôde ser sugerido pelo exame físico e confirmado por ecodopplercardiograma, que permitiu estimar a pressão sistólica em artéria pulmonar em 80mmHg. Tratamento foi iniciado com nifedipina; entretanto, devido a efeitos colaterais da droga, não foi possível o aumento da dose além de 30mg ao dia; nesta dosagem, a nifedipina não acarretou redução da pressão arterial pulmonar.Systemic sclerosis (SS is an uncommon disease characterized by small blood vessel vasculopathy and increased connective tissue in the skin and in other organs. The pulmonary involvement is common in SS; however, pulmonary hypertension without interstitial fibrosis is rare. The authors present a case of the diffuse form of SS with isolated pulmonary hypertension. The diagnosis of pulmonary hypertension was suggested by physical examination and confirmed by doppler-echocardiography which allowed for the estimation of the pulmonary artery systolic pressure in 80 mmHg. The authors started treatment with nifedipine; however, as the patient presented side effects, it was not possible to increase the dose beyond 30 mg/day. In this dosage, nifedipine did not decrease the pulmonary arterial pressure.

    Full Text Available A esclerose sistêmica (ES é uma enfermidade inflamatória crônica idiopática, cujo principal indício de vínculo com a auto-imunidade é a presença de auto-anticorpos na maior parte dos pacientes. Pelo teste de imunofluorescência indireta em células HEp-2, observa-se reatividade predominantemente contra o nucléolo e o núcleo, sendo que títulos de anticorpos antinucléolo acima de 1/640 são fortemente sugestivos de ES. Alguns desses auto-anticorpos apresentam alta especificidade para a ES, sendo considerados marcadores diagnósticos dessa enfermidade. São exemplos os anticorpos anti-Scl-70, antifibrilarina e anti-RNA polimerase I. Outros apresentam interessantes associações com manifestações específicas da ES, como os anticorpos anticentrômero, associados às formas limitadas, os anticorpos anti-RNA polimerase III, associados ao extenso comprometimento da pele, e os anticorpos anti-To/Th, associados às formas limitadas com propensão ao desenvolvimento de hipertensão pulmonar. Algumas dessas associações estão bem estabelecidas em diversos estudos, de diferentes grupos de pesquisadores. Outras, entretanto, devem ser vistas com cautela, pois a exigüidade de casos disponíveis para estudo pode ensejar conclusões preliminares e não acuradas. A detecção de anticorpos anticentrômero por técnica de IFI e anti-Scl-70 por imunodifusão dupla ou por ELISA está disponível nos principais laboratórios clínicos capacitados na área de auto-imunidade. O mesmo não se aplica para a maior parte dos demais auto-anticorpos associados à ES. Espera-se que, com a implementação rotineira de técnicas para detecção desses outros auto-anticorpos, o real significado clínico dos mesmos venha a ser melhor conhecido.Systemic Sclerosis (SS is a chronic idiopathic inflammatory disease whose main hint towards autoimmunity is given by the presence of high serum levels of autoantibodies in the majority of the patients.

A capilaroscopia periungueal (CPU é um método estabelecido para avaliação do componente morfológico no fenômeno de Raynaud secundário à ES. No presente estudo pretende-se a confrontação dos achados da capilaroscopia periungueal com os dados da LPD-EF em dedos individuais de pacientes com esclerose sistêmica. MÉTODOS: Foram avaliados 14 pacientes com diagnóstico de ES e que apresentassem 3 dedos com grau discrepante de microangiopatia SD à CPU. Foi realizada dosagem da lacticemia de polpa digital nos três dedos selecionados em condições basais (LPD pré-EF e 10 minutos após estímulo frio (LPD pós-EF. A variação percentual das medidas de LPD pós-EF em relação à LPD pré-EF foi denominada ΔLPD. RESULTADOS: Houve acentuada variabilidade intraindividual (entre os diversos dedos nos parâmetros do teste do LPD-EF. Não encontramos diferença estatisticamente significante nos valores da LPD pré-EF, pós-EF ou ΔLPD ao compararmos os dedos com padrão capilaroscópico semelhante com os dedos díspares nos 14 pacientes com ES. Não houve correlação entre a intensidade dos achados morfológicos, registrados pela CPU, e as alterações funcionais, medidas pelo teste LPD-EF. CONCLUSÕES: A ausência de correlação entre as alterações microangiopáticas morfológicas verificadas pela CPU e as alterações funcionais de perfusão, avaliadas pelo teste da LPD-EF, sugere a possibilidade de que as últimas estejam relacionadas a lesões vasculares proximais, como arteríolas, artérias digitais e arco palmar.OBJECTIVE: The cold stimulus-fingertip lacticemy test (CS-FTL evaluates a microcirculation biochemical component and presents abnormal results in systemic sclerosis (SSc.

METHODS: Eighteen female SSc patients (eight patients presenting cutaneous ischemic ulcers were submitted to indirect measurement of the PVP (by plethysmography, and data were compared with a control group of 18 healthy women, paired by age. RESULTS: Arterial pressure levels were similar in both groups. PVP levels were significantly decreased in the SSc patients (58.9 ± 11.6 mmHg in the SSc group and 96.9 ± 7.1 mmHg in the control group; p < 0.0001; in the SSc group, patients with ischemic ulcers presented PVP levels significantly decreased compared with those patients without ulcers (50.6 ± 10.8 mmHg in the ulcer group and 65.5 ± 7.2 mmHg in the group without ulcers; p = 0.006. CONCLUSIONS: It can be concluded that decreased PVP in SSc is associated with a decrease in the blood flow of these patients, predisposing them to cutaneous ischemic ulcers.

O presente estudo buscou verificar em modelo experimental, o efeito da corrente elétrica galvânica em baixa amperagem. Foram utilizados 45 coelhos Nova Zelandia, distribuídos em 3 grupos de 15 animais , sendo utilizada a orelha esquerda como controle e a orelha direita como experimento. No grupo experimento os animais do grupo I foram submetidos à corrente elétrica galvânica de 100m A , no grupo II à 200m A, e no grupo III à 300m . No grupo controle, os animais foram submetidos somente ao procedimento mecânico de aplicação da agulha ao longo da veia marginal da orelha esquerda, sendo realizado uma, duas e três aplicações com intervalo de sete dias entre cada aplicação. Todos os animais foram avaliados quatorze dias após a última aplicação, em aspectos macro e microscópicos. Os resultados mostraram que, tanto a corrente elétrica galvânica em baixa amperagem, quanto o simples trauma mecânico da agulha, não são capazes de produzir esclerose na veia marginal da orelha do coelho que seja estatisticamente significante.Telangiectases, in accordance with current concepts, must be treated in a surgical way.

    Full Text Available Il seminario di Igino Bozzetto sul ricongiungimento familiare diventa opportunità per riflettere sulle connessioni tra cornice sistemica - nella variante che conosciamo come cibernetica di secondo ordine - e studio della comunicazione interculturale. Bozzetto mostra come i concetti chiave dell'approccio sistemico nella sua declinazione sociocostruzionista trovano applicazione nel delicato lavoro con le famiglie immigrate ed i minori. In particolare la polifonia, che caratterizza l'approccio sistemico, diventa la chiave per entrare in relazione con l'altro, una cornice per la convivenza di punti di vista e per l'esercizio della curiosità.

    Full Text Available Os autoanticorpos possivelmente influenciam as manifestações clínicas da esclerose sistêmica (ES. Essa correlação clínico-sorológica, associada à insuficiência de casos de concomitância de autoanticorpos, originou o paradigma histórico de que seriam mutuamente excludentes. Porém, pode-se questionar essa tese. Poderia a multiplicidade de autoanticorpos significar a coexistência de duas patologias distintas? Por outro lado, se assumidos como anticorpos específicos de uma doença única, essa multiplicidade seria um evento aleatório ou representaria um subgrupo distinto de pacientes, com características clínicas, patogênicas e imunogenéticas próprias? A prevalência de autoanticorpos na ES precoce é elevada. Entretanto, a duplicidade do anticorpo anticentrômero (AAC e do anticorpo antitopoisomerase 1 (AAT é um evento raro. Já a coexistência de AAC, AAT e anticorpo anti-RNA polimerase (anti-RNA-P III ainda não foi descrita em um paciente isolado. Neste relato, com positividade para AAC, AAT e anti-RNA-P III, notamos manifestações vasculares precoces e posterior comprometimento cutâneo limitado. Este parece ser o primeiro relato de concomitância de três autoanticorpos específicos em um paciente com ES. Acreditamos que essa coexistência representa um subgrupo sorológico raro de uma única doença, com possível valor clínico e prognóstico - porém, ainda há necessidade de confirmação.Autoantibodies possibly influence clinical manifestations of systemic sclerosis (SSc. This clinical-serological correlation, associated with the paucity of autoantibodies concomitance, gave rise to the historical paradigm of autoantibodies mutual exclusivity. However, one can question this assumption. Does autoantibodies concomitance mean coexistence of two different entities? On the other hand, if considered a unique disease, is this phenomenon a random event or does it represent a distinct subgroup of patients, with peculiar

Quando os músculos responsáveis pela ventilação são acometidos, o paciente evolui para o óbito em alguns anos em decorrência da insuficiência respiratória. RELATO DO CASO: Sexo feminino, 63 anos, esclerose lateral amiotrófica, submetida a tratamento cirúrgico de fratura transtrocantérica de fêmur. Quadro de fraqueza em membros superiores e inferiores, disartria, consciente e orientada. Aparelho respiratório: tosse ineficaz, diminuição da força dos músculos intercostais e diafragma e redução do murmúrio vesicular em bases pulmonares. Primeiramente, a punção peridural foi realizada em L3/L4, onde um cateter de silicone foi introduzido 5 cm. A seguir, a punção raquidiana foi feita em L4/L5 com administração de 7,5 mg de bupivacaína hiperbárica. Mais 37 mg de ropivacaína a 0,37% foram administrados pelo cateter peridural para que o bloqueio sensitivo alcançasse o dermátomo T10. O procedimento transcorreu sem complicações e a paciente recebeu alta hospitalar após três dias. CONCLUSÕES: As evidências têm demonstrado que a administração de bloqueios no neuroeixo parece ser segura em pacientes com esclerose lateral amiotrófica, pois evita a manipulação das vias aéreas e as complicações ventilatórias.JUSTIFICATIVA Y OBJETIVOS: La esclerosis lateral amiotrófica es una enfermedad que empieza entre la quinta y la sexta década de vida y que provoca la degeneración y la muerte de las neuronas motoras superiores e inferiores.

    Full Text Available Esclerose múltipla é uma doença desmielinizante, que leva à destruição de importantes estruturas do Sistema Nervoso Central. Essas lesões podem resultar em déficits cognitivos. Com o objetivo de investigar a relação entre esclerose múltipla e alterações cognitivas de atenção, memória e percepção, foram avaliados 28 pacientes em um Centro Estadual de Referência, que satisfaziam os critérios de inclusão: idade entre 20 e 55 anos, nível escolar mínimo de 2º grau completo e classificação na Escala Expandida de Incapacidade menor que 7,0. Foram empregados quatro testes neuropsicológicos, validados pelo Conselho Federal de Psicologia: teste da cópia e reprodução de memória da figura complexa A de Rey-Osterrieth, teste de aprendizagem áudio-verbal de Rey, teste d2 e teste de dígitos. Para investigar o impacto da fadiga sobre as atividades cognitivas foi utilizada a escala MFIS-21Br. A análise estatística consistiu dos testes ANOVA, t para amostras pareadas ou de Mann-Whitney e de Kolmogorov-Smirnoff, unicaudais à direita, para rejeição da hipótese nula com nível de significância de 0,05. Os resultados apontaram perdas cognitivas com significância estatística nos pacientes com idade entre 40 e 55 anos e nos que apresentaram comprometimento por fadiga nos subdomínios cognitivo e psicossocial. Os pacientes com tempo de doença entre 5,0 e 19,9 anos apresentaram redução da pontuação nos testes, mas sem significância estatística. Concluiu-se que, dentre as funções cognitivas avaliadas, memória foi a mais freqüentemente comprometida, seguindo-se de atenção, sendo a percepção, comparativamente, a mais preservada.Multiple sclerosis is a demyelinating disease that leads to the destruction of important structures of the Central Nervous System.

    Full Text Available Episodic memory is impaired in multiple sclerosis (MS patients, possibly because of deficits in working memory (WM functioning. If so, WM alterations should necessarily be found in patients with episodic memory deficits, but this has not yet been demonstrated. In this study we aimed at determining whether episodic memory deficits in relapsing-remitting MS are found in conjunction with impaired WM. We evaluated 32 MS patients and 32 matched healthy controls. Nineteen of the 32 patients had episodic memory impairment, and as a group only these individuals showed deficits in WM capacity, which may lead to difficulty in encoding, and/or retrieving information from episodic memory.Pacientes com esclerose múltipla (EM apresentam prejuízo de memória episódica possivelmente em decorrência de um déficit no funcionamento da memória operacional (MO. Se assim fosse, alterações de MO seriam necessariamente encontradas em pacientes com déficit de memória episódica, mas isto ainda não foi demonstrado. Neste estudo tivemos como objetivo determinar se déficits de memória episódica em pacientes com EM recorrente-remitente são encontrados em associação com prejuízo de MO. Avaliamos 32 pacientes com EM pareados com 32 voluntários saudáveis. Dezenove dos 32 pacientes apresentaram prejuízo de memória episódica, e como grupo, somente estes indivíduos apresentaram déficit na capacidade de MO, o que deve resultar na dificuldade de codificar, e /ou recuperar informações da memória episódica.

    Full Text Available INTRODUÇÃO: A esclerose nodular (EN, do tipo histológico freqüente do linfoma de Hodgkin (LH, apresenta grande variabilidade em sua composição celular. Na década de 80, pesquisadores do British National Lymphoma Investigation (BNLI propuseram uma subclassificação histológica do LH EN. Eles identificaram dois graus histológicos - o LH EN grau I (LH EN I e o LH EN grau II (LH EN II - e demonstraram que os portadores de LH EN II apresentavam menor sobrevida em comparação aos portadores de LH EN I. Outros estudos, entretanto, não reproduziram esses achados. OBJETIVO: Avaliar o significado prognóstico da graduação histológica proposta pelo BNLI. MATERIAIS E MÉTODOS: Estudo retrospectivo que incluiu 69 casos de LH EN. Mais de 90% dos casos foram tratados com terapia combinada ou quimioterapia exclusiva, não havendo diferença no tipo de tratamento oferecido a depender do grau histológico. RESULTADOS: Trinta e cinco casos (51% foram classificados com EN I e 34 (49% como EN II. Não observamos diferenças na distribuição de outros fatores prognósticos entre os portadores dos dois graus. Remissão completa após o tratamento inicial foi obtida em 85,7% dos casos de EN I e em 82,4% dos casos de EN II (p = 0,75. A probabilidade estimada de sobrevida global em cinco anos foi de 67% para EN I e de 83,5% para EN II (p = 0,13 e a taxa de sobrevida livre de doença em cinco anos foi de 85,2% versus 87%, respectivamente (p = 0,72. CONCLUSÃO: Nesta população de pacientes uniformemente tratados a graduação histológica BNLI não esteve associada com o prognóstico do LH EN.BACKGROUND: Nodular sclerosis (NS, a frequent histological subtype of Hodgkin’s lymphoma (HL, presents great variability in its cellular composition.

    Full Text Available Up to now, the G20 has supervised the process to revitalize the real economy affected by the Great Recession through fiscal stimuli and a very easy monetary policy, and to rescue the battered financial system by injecting capital into giant banks and firms. The G20 is now turning its attention to financial regulation, with the FSB as its main operational arm. The ideas that are being proposed stress the need for disincentives toward too much risk taking (more capital, higher liquidity, limits to remunerations and bonuses, etc., particularly by big and complex financial institutions that are likely to entail systemic risks. The paper maintains that, as the disincentive approach is insufficient to deter financial managers looking for power, some kind of segmentation needs to be introduced, as suggested by Paul Volcker.

    Full Text Available Neste trabalho, foram revisadas a literatura internacional e a experiência nacional com transplante de células-tronco hematopoéticas (TCTH para doenças autoimunes. A evidência acumulada indica que o TCTH autólogo pode beneficiar pacientes com esclerose múltipla em fase inflamatória, refratária aos tratamentos medicamentosos disponíveis, e pacientes com esclerose sistêmica cutânea difusa de caráter progressivo, com ou sem comprometimento sistêmico. Esse tratamento deveria ser disponibilizado na rede pública de saúde, numa fase inicial, em centros de referência com experiência em TCTH e no manejo clínico de doenças autoimunes sistêmicas graves.In this paper, international literature and national experience on hematopoietic stem cell transplantation (HSCT for autoimmune diseases were reviewed. Cumulative evidence indicates that autologous HSCT may benefit patients with inflammatory multiple esclerosis, refractory to available drug therapy, and progressive forms of diffuse cutaneous systemic sclerosis with or without systemic involvement. Initially, this treatment should be available in reference centers of the public health system, with experience in performing HSCT and in treating severe systemic autoimmune diseases.

    Full Text Available Tuberous sclerosis (also referred to as Tuberous Sclerosis Complex is an autosomal dominant neurocutaneous syndrome that can involve multiple organs such as the brain, heart, kidney, lung, liver, skin and eye. The diagnosis is clinical and most patients are identified during childhood, in the context of a severe epileptic or neuropsychiatric disorder. Here we report a case of TSC diagnosed in an adult woman with dermatological and vascular involvement that were only recognized as manifestations of TSC after the diagnosis of her infant daughter. This case highlights how important it is that physicians recognize the full spectrum of manifestations of TSC, including the most unusual, so not to miss the diagnosis

    Full Text Available Primary progressive multiple sclerosis (PPMS is defined clinically with a progressive course from onset. There is no approved treatment for the PPMS. Methylprednisolone IV (MP hastens the recovery from MS relapses. We studied 11 patients that met the MacDonald's diagnostic criteria for PPMS. The dose of MP was 30 mg/kg in 250 mL of glucose solution in three consecutive days during the first week, two doses during the second and one dose in the third week. One weekly session for eight consecutive weeks was given. After, a once-a week/eight-week interval was maintained. The medium EDSS before treatment was 6.2, and after 11.2 years of treatment, the EDSS was 4.9. Although we studied a small sample of PPMS we may conclude that therapy with IVMP prevents clinical worsening of MS in the majority of patients with improvement in EDSS scores.A forma progressiva da esclerose múltipla (FPEM é definida como progressiva desde o início. Não há tratamento eficaz para esta forma. A metilprednisolona por via endovenosa (MPEV é usada para os surtos de exacerbação da EM. Estudamos 11 pacientes que preenchiam os critérios de MacDonald para FPMS. A dose inicial de MPEV foi de 30 mg/kg em 250 mL de soro glicosado por três dias consecutivos na primeira semana, duas doses na segunda e uma dose na terceira semana. Seguiu-se uma sessão semanal por oito semanas. Após manteve-se uma dose semanal a cada oito semanas. A média do EDDS foi 9,6 antes e 4,9 após 11,2 anos de tratamento. Embora tenhamos estudado número reduzido de casos, podemos dizer que o uso de MPEV impede a progressão da FPEM na maioria dos pacientes estudados com melhora do EDDS.

Poucos tratamentos são considerados eficazes para a doença com intenso envolvimento de pele como a ES na forma difusa. Portanto, avaliamos a eficácia da ciclofosfamida no tratamento de pacientes com ES difusa grave. PACIENTES E MÉTODOS: Nove pacientes com ES difusa (Critérios do Colégio Americano de Reumatologia [ACR] com escore de Rodnan de pele modificado (ERM > 30 (0-51 foram submetidos ao tratamento com ciclofosfamida (CFM EV na dose de 0,5 a 1,0 g/m² mensal por 18 meses, totalizando 18 pulsos. Além da realização do ERM a cada seis meses, exames laboratoriais e avaliação de efeitos adversos foram também analisados. Pacientes com doença pulmonar e envolvimento cardíaco foram excluídos. RESULTADOS: A maioria dos pacientes era do sexo feminino (77%, com média de idade de 41,7 anos e tempo de doença de 2,2 anos. Observou-se redução significativa do ERM de 37,7 ± 4,08 para 29,1 ± 8,13 após 12 meses de tratamento (P = 0,009.

    Full Text Available A esclerose múltipla (EM é afecção neurológica que acomete principalmente adultos jovens e evolui, geralmente, para graus variados de incapacidade física dos pacientes. Assim, a abordagem destes pacientes faz com que o médico depare-se com diversas questões éticas. OBJETIVO: Identificar as percepções de médicos e pacientes sobre a doença e, com isso, melhorar o relacionamento médico-paciente. MÉTODO: Foram feitos dois questionários, um respondido por 44 médicos e outro, por 103 pacientes, abordando questões sobre o diagnóstico e a conduta na EM. RESULTADOS: 96,1% dos pacientes sabiam seu diagnóstico, os outros gostariam de sabê-lo. Daqueles, 74,7% achavam que a forma contada foi correta e 90,9% que o médico é que deve contá-lo. Os sintomas que mais os incomodam são a fadiga (29,1% e os déficits motores (28,1%. Por outro lado, 68% dos pacientes afirmaram sofrer com a doença. O motivo mais importante para os médicos contarem o diagnóstico foi para melhorar a adesão ao tratamento (56,8%. A presença de um familiar neste momento é exigida por 54,6% dos médicos. Quando perguntados sobre as orientações de uma gravidez, 50% dos médicos não responderam adequadamente. Finalmente, 50% dos médicos manifestaram-se de forma contrária às terapias complementares. CONCLUSÃO: Os pacientes querem saber seu diagnóstico e o médico deve contá-lo da forma mais adequada e dar mais informações. Um debate sobre cuidados paliativos também faz-se necessário.Multiple sclerosis (MS is a neurologic disorder that mostly affects young adults and can usually evolute to physical disability.

    Full Text Available Nell’articolo il rapporto tra sistemi di accessibilità (ferroviaria e stradale e grandi rischi viene affrontato da due diverse prospettive. La prima vede tali sistemi come esposti e vulnerabili a diverse forme di pericolosità naturale; la seconda li considera invece quali potenziali fonti di pericolo, indagando in particolare il trasporto di sostanze pericolose. Per quanto riguarda la prima parte dell’articolo, ovvero l’analisi di vulnerabilità delle infrastrutture di trasporto a diversi agenti naturali, verranno esplicitati i fattori di vulnerabilità fisica, sistemica e organizzativa. A sostegno della modellazione proposta, si fa riferimento sia alla letteratura internazionale sia al metodo sviluppato presso il Politecnico di Milano, nei suoi ultimi sviluppi. Interessa infatti presentare un metodo relativamente semplice da utilizzare a scala vasta per poi scendere nel dettaglio necessario laddove le priorità individuata a grande scala ne indichino la necessità. Tra i fattori di vulnerabilità fisica si indicheranno gli elementi maggiormente critici per diversi tipi di sollecitazione (sismica, vulcanica, alluvionale, etc.; per quanto attiene ai fattori di vulnerabilità sistemica si considerano le interdipendenze tra reti e sistemi (inclusi gli altri servizi a rete; per quanto attiene alla vulnerabilità organizzativa si indicheranno le difficoltà nel produrre un sistema integrato di allertamento, che consenta ad esempio di chiudere tratti di strada quando questi vengano segnalati come imminentemente interessati da un dato evento estremo. Infine si indicheranno i danni che il sistema di accessibilità può subire e le ripercussioni di questi sul territorio di interesse. Nella seconda parte viene trattato un particolare tipo di trasporto, quello delle sostanze pericolose, differenziando opportunamente tra ferroviario e stradale. Il ribaltamento del punto di vista comporta la necessità di identificare in modo puntuale i fattori di

    To compare the characteristic MR findings of infectious sacroiliitis (IS) and ankylosing spondylitis (AS). We retrospectively reviewed MR findings in eight patients with IS (pyogenic in six, tuberculosis in two) confirmed by culture and clinical follow-up, and in six with AS by HLA-B27 typing. AA control group of 13 asymptomatic volunteers was formed, and they underwent MRI Findings were analysed for morphology, degree of bone erosion, and adjacent soft tissue change. CT findings of AS in four patients and IS in four were also compared to MR findings. MR characteristics of IS included unilaterality (100%), abnormal cartilage signal intensity (100%), bone marrow change (100%), contrast enhancement (100%), erosion (63%), and soft tissue change (63%). MR findings of AS showed bilaterality (67%), abnormal cartilage signal intensity (80%), bone marrow change (80%), erosion (80%), contrast enhancement (44%) and soft tissue change (10%). CT scan showed bony sclerosis and erosion (86%), and abnormal joint space (71%). MR findings of sacroiliitis were loss of thin zone of a cartilage and erosions on T1-weighted image, and increased signal intensity on T2-weighted image. MRI is regarded as a useful diagnostic method where conventional diagnosis is difficult, and is able to image cartilage abnormalities directly and noninvasively. Significant differences in MR findings between IS and AS were not noted, however

METHOD: We studied 251 cases, all of which fulfilled the diagnosis criteria proposed in El Escorial (WFN. Between 1977 and 2004, 157 male and 94 female patients were examined. RESULTS: 220 cases were classified as ALS-Spinal Onset (ALS-SO, 24 as ALS-Bulbar Onset (ALS-BO and 7 as Familial ALS. The mean age at time of evaluation was 54.4±12.3 years, and symptoms had started 17.9±15.7months previously. In the group studied, statistical relationships were found between heavy occupations and males; previous surgeries and females; ALS-BO and dysphagia and dysarthria in females; and ALS-SO and males, cramps, weakness, muscle atrophy, hypertonia, increased deep tendon reflex and abnormal gait. CONCLUSION: The average age at time of evaluation was lower than that registered in the literature but similar to the Brazilian series. Domestic work and heavy occupations appear to be related to precocious perception of the symptoms by interference with daily functions. The socioeconomically higher classes seek medical care early. There was no relationship with exposure to toxic agents or trauma.OBJETIVO: Estudar as formas clínicas de esclerose lateral amiotrófica (ELA e possíveis fatores de risco, a fim de verificar se existem diferenças entre os casos do Paraná, Brasil.

    Full Text Available È ampio il divario fra le azioni necessarie per evitare un surriscaldamento dannoso del pianeta e quelle decise per contrastarlo. Più passa il tempo più le visioni pessimiste acquistano motivazioni e argomenti validi. Per trasformare radicalmente in pochi decenni un sistema energetico e un rapporto predatorio verso le risorse del pianeta è necessario riconoscere la crisi climatica nella sua dimensione sistemica, nel suo essere prima di tutto un problema di giustizia, di equità anche verso le generazioni future. La scienza del clima dovrebbe aiutare a capire la portata della sfida chiarendo meglio le conseguenze delle scelte odierne per le generazioni future. Ma uno sforzo molto più grande è quello di recuperare le ragioni per occuparci, come individui e comunità, dei nostri posteri. Capire la posta in gioco sul tema del cambiamento climatico richiede non solo più conoscenza, ma di accettare l’esistenza dei limiti planetari, di ridefinire le aspettative amane, nonché un livello di intelligenza emotiva oggi insufficiente.

All imaging findings were analyzed according to the American College of Radiology (ACR) breast imaging reporting and data system (BI-RADS). Radiologic features were correlated with pathologic findings. Although most mammograms showed negative findings (57%), calcification was the most common abnormal finding of sclerosing adenosis. On sonography, the most common finding was a circumscribed oval hypoechoic mass without posterior features (78%). Most masses showed BI-RADS category 3, (75%, 27/36). Five cases showed categories 4 or 5 (14%, 5/36). Most mammographic and sonographic findings of sclerosing adenosis are non-specific and non-pathognomonic, even though sometimes sclerosing adenosis can be radiologically or histopathologically confused with malignancy

    To evaluate prenatal ultrasonographic findings of limb-body wall complex and to correlate them with autopsy findings. From October 1995 to June 2000, a retrospectively review of prenatal ultrasonography (US) of 11 patients with pathologically proven limb-body wall complex was done. US findings were then compared with autopsy findings. Prenatal ultrasonography revealed thoraco-abdominoschists (n=7.64%), kyphoscoliosis (n=7.64%), cranial defect (n=5.45%), limb defect (n=4.36%), facial defect (n=1.10%), amniotic band (n=5.45%), and umbilical cord anomaly (n=3.27%). Meanwhile, autopsy findings showed thoraco-abdominoschisis (n=8.72%), limb defect (n=7.64%), facial defect (n=7.64%), kyphoscoliosis (n=5.45%), cranial defect (n=5.45%), amniotic band (n=5.45%) and umbilical cord anomaly (n=4.36%). The most common ultrasonography features of limb-body wall complex were thoraco-abdominoschisis and kyphoscoliosis while the thoraco-abdominoschisis and limb defects were the most frequent findings at autopsy.

    Imaging findings in delayed presentation of congenital diaphragmatic hernia can be confusing and misleading, resulting in a delay in diagnosis. To evaluate the often puzzling plain film findings of late-presenting CDH in an effort to determine whether any of the findings could be helpful in arriving at an early diagnosis. We reviewed and documented the plain film findings and clinical data in eight patients seen during the last 20 years with late-presenting CDH. IRB exempt status was obtained in this study. There were five boys and three girls. The age range was 4 months to 12 years with a mean of 2.4 years. Five children presented with acute respiratory problems while three presented with acute abdominal pain. Two children presented with both respiratory and abdominal findings and one also presented with hematemesis. Two children had radiographic findings that were not difficult to analyze while the remaining six had findings that posed initial diagnostic problems. Although not common, late-presenting CDH can result in confusing plain film radiographic findings and a delay in diagnosis. We found that the most important finding in analyzing these radiographs is in evaluating the location and position of the gastric bubble with the more common left-side hernias. (orig.)

    Full Text Available A esclerose sistêmica (ES é uma doença sistêmica caracterizada por microangiopatia, exuberante atividade do fibroblasto e anormalidades imunológicas. A faceta microangiopática é responsável pela maioria das complicações com potencial mortalidade. A interação entre o endotélio e as plaquetas desempenha um papel importante na fisiopatologia da ES. Evidências de ativação plaquetária na ES incluem níveis séricos elevados de substâncias derivadas das plaquetas (fator 4 plaquetário, fator de Von Willenbrand, tromboxane A2 e ß-tromboglobulina, agregados plaquetários circulantes, anormalidades ultraestruturais nas plaquetas e a presença de plaquetas aderidas ao endotélio. A presente revisão aborda de forma crítica os princípios e problemas potenciais dos principais métodos de avaliação da função e ativação plaquetárias. A avaliação da capacidade de agregação das plaquetas é feita com e sem a adição de agonistas (adenosina difosfato, colágeno e adrenalina. A ativação plaquetária pode ser avaliada de duas formas: pela dosagem da concentração plasmática de substâncias que são liberadas pela ativação plaquetária (ex., tromboxane, fator 4 plaquetário e pela mensuração da expressão em membrana plaquetária de moléculas que são transportadas para a membrana plaquetária durante o processo de ativação das plaquetas (ex., GMP-140 e glicoproteína IIb/IIIa. Uma contribuição recente para este campo foi dada pela demonstração de que a enolase específica de neurônios (NSE é liberada das plaquetas para o plasma em pacientes com ES em atividade. Assim, a dosagem da NSE, que é um exame disponível nos principais laboratórios com ênfase na dosagem de marcadores tumorais, pode se tornar um marcador de atividade plaquetária de grande utilidade em diversas condições clínicas.Systemic sclerosis (SSc is a multisystemic disease characterized by microangiopathy, exuberant fibroblast activity and

    To evaluate ultrasonographic (US) findings of right-side colonic diverticulitis and to correlate them with pathologic findings. Twenty nine patients with surgically (n=7) and radiographically (n=8) proven diverticulitis in the cecum and ascending colon for the past five years were included in this study, and they all underwent US due to right lower quadrant abdominal pain. US findings were analyzed by two radiologists with a special emphasis on: (1) the presence, size, and internal echo of hypoechoic lesion bulging out from the colonic wall (thickened diverticulum), (2) changes in the adjacent cecum and ascending colon, (3) changes in the adjacent mesentery, (4) accompanying fluid collection, and (5) the presence of lymphadenopathy. US finding of 18 surgically proven patients were correlated with pathologic findings. On US, 25 of 29 patients (86.2%0 were found to have thicken diverticulum with the greater dimension of 8-20 mm (mean,, 12 mm). Wall thickening of the adjacent cecum and ascending colon was seen in 28 patients (96.5%), and 22 (75.9%) of them had eccentrically thickened wall. Comparing US findings with pathologic findings in 18 surgically proven patients, all revealed to have inflamed diverticulum on surgery, but only 15 showed thickened diverticulum on US. In 12 patients, fecalith, purulent exudates, and hemorrhage were found within diverticulum on surgery. In case of diverticulitis containing fecalith, all of their echogenecities were increased. All patients showed wall thickening of the adjacent colon and increased echogenecity of the adjacent mesentery on US. Pathologic findings of these thickened walls contained nonspecific inflammatory change and hemorrhage while the mesentery with an increased echogenecity contained purulent or hemorrhagic exudates. Ultrasonography can diagnose the right-side colonic diverticulitis when there is the presence of thickened diverticulum in the area with the thickened right side colonic wall in patients with right

    The imaging findings of complex fibroadenoma have been rarely reported even though the risk of developing breast carcinoma in a patient with complex fibroadenoma is higher than that for a patient with simple fibroadenoma. We reviewed the imaging features and pathologic findings of complex fibroadenomas. Between April 2003 and April 2010, the mammographic and sonographic findings of five patients with complex fibroadenomas were retrospectively reviewed according to the Breast Imaging Reporting and Data System (BIRADS). The pathologic findings were retrospectively reviewed for all 5 patients. The mammography findings showed masses (3 cases) and asymmetry (1 case). On ultrasonography, complex echo patterns were noted in all the patients, and all the lesions were assigned to BI-RADS category 4, suspicious for abnormality. The complex echoic patterns showed two types: 1) a mixture of a heterogeneous hypoechoic central portion and a fuzzy hyperechoic peripheral area in 2 cases, 2) a mixture of tiny anechoic and hypoehoic lesions in 3 cases. Multiple cystic changes were noted in all the cases on the pathologic analysis. Complex fibroadenomas showed different ultrasonographic findings from simple fibroadenomas such as two types of complex echo patterns, even though the other findings were similar to those of simple fibroadenoma. Cystic changes were noted in all the cases on the pathologic analysis. Awareness of these imaging findings will help us to properly diagnose complex fibroadenoma

    Full Text Available Academic researchers often need and re-use relevant information found after a period of time. This preliminary study used various methods, including experiments, interviews, search log analysis, sequential analysis, and observation to investigate characteristics of academic information finding and re-finding behavior. Overall, the participants in this study entered short queries either in finding or re-finding phases. Comparatively speaking, the participants entered greater number of queries, modified more queries, browsed more web pages, and stayed longer on web pages in the finding phase. On the other hand, in the re-finding phase, they utilized personal information management tools to re-find instead of finding again using search engine, such as checking browsing history; moreover, they tend to input less number of queries and stayed shorter on web pages. In short, the participants interacted more with the retrieval system during the finding phase, while they increased the use of personal information management tools in the re-finding phase. As to the contextual clues used in re-finding phase, the participants used less clues from the target itself, instead, they used indirect clues more often, especially location-related information. Based on the results of sequential analysis, the transition states in the re-finding phase was found to be more complex than those in the finding phase. Web information finding and re-finding behavior is an important and novel area of research. The preliminary results would benefit research on Web information re-finding behavior, and provide useful suggestions for developing personal academic information management systems.

Assinalam a dificuldade para o estabelecimento de uma classificação, em virtude da falta de conhecimento dos agentes etiológicos desencadeantes na maioria dos casos. Apresentam uma observação anátomo-clínica de mielo-patia neuro-óptica com artério e arteriolosclerose, em que a doença se iniciou pelo acometimento do nervo óptico direito, e, somente dois meses depois, surgiram os primeiros sinais de acometimento da medula espinal. No quarto mês de doença estabeleceu-se, de modo completo, o quadro medular, com uma sindrome motora tetraplégica pirâmido-extrapiramidal, outra motora primária nas extremidades distais dos membros superiores, por acometimento das pontas anteriores e, finalmente, uma sindrome sensitiva de tipo cordonai, abrangendo todas as formas de sensibilidade, a partir de C3. A enfermidade evoluiu em 12 meses, ocorrendo a morte em conseqüência de insuficiência respiratória de origem bulbar provável. O exame anátomo-patológico mostrou atrofia e esclerose total dos nervos ópticos, discretos infiltrados parvicelulares em torno de alguns vasos intracerebrais e piais e, na medula, um quadro histopatológico comparável ao que de regra se encontra na oftalmoneuromielite; apenas, no segmento cervical, onde as lesões eram muito extensas, havia foco de amolecimento mais pronunciado do que aqueles que se observam mais freqüentemente. 0 fato talvez decorra de esclerose arterial concomitante existente neste caso. Havia, também, lesões bulbares discretas.

A associação de ictiose com esclerose sistêmica foi descrita em apenas três crianças. Ainda não foi descrito nenhum paciente com morfeia generalizada (MG associada à ictiose arlequim. Relato de caso: Menina de quatro anos e seis meses de idade com diagnóstico de ictiose arlequim baseado em espessamento cutâneo difuso, com fissuras, descamação, eritema e sangramento da lesão desde as primeiras horas de vida. A paciente foi tratada com acitretina (1,0 mg/kg/dia e creme emoliente. Aos três anos e nove meses, desenvolveu contraturas musculares com dor à movimentação e limitação nos cotovelos e joelhos e placas esclerodérmicas difusas no abdômen, nas costas, na região suprapúbica e nas extremidades inferiores. A biópsia de pele mostrou epiderme retificada e hiperqueratose leve, derme reticular com linfócitos, infiltrado mononuclear perivascular e perianexial e esclerose da derme reticular e glândula sudorípara rodeada por um tecido colágeno denso, compatível com esclerodermia. A paciente preencheu os critérios para o subtipo MG. Metotrexato e prednisona foram introduzidos. Aos quatro anos e três meses, apresentou novas lesões esclerodérmicas, associando-se azatioprina à terapêutica anterior, sem resposta após dois meses. Discussão: Um caso de ictiose arlequim associada à MG foi descrito. O tratamento dessas duas condições é um desafio e requer uma equipe multidisciplinar.

    Parenchymal iron deposition occurs in hemochromatosis, while iron is deposited in reticuloendothelial cells after blood transfusions(Hemosiderosis). We studied correlation between MR finding and clinical findings(serum ferritin, TSI, LFT, disease duration) of hemosiderosis. 12 patients with chronic renal failure and one patient with aplastic anemia, who have received multiple transfusion, were performed MRI with a 2.0 Tesla unit. In all of 13 patients(17 cases), the liver revealed low signal intensity equal to background noise. In 4 of 17 cases whose serum ferritin level was below 1000 ng/ml, pancreas, gastric wall, adrenal gland were involved in 1 case. In 4 cases with serum ferritin level between 1000 and 1500, pancreas was involved in 2 cases, and other organ was involved in 1 case. In 9 cases with serum ferritin level above 1500ng/ml, pancreas was involved in 9 cases, and other origin 4 cases. The MR findings are well correlated with serum ferritin level whereas the TSI, LFT, disease duration are not correlated with involved organ on MR.

    To evaluate the CT findings of focal organizing pneumonia and to correlate them with pathologic findings to help differentiating from lung cancer. We evaluated radiologic and pathologic findings of five patients with solitary pulmonary nodule which were confirmed as focal organizing pneumonia pathologically. On CT scan, focal organizing pneumonia had irregular margin contacting the pleura in all five cases. The shape of the nodules were spherical to wedge or elliptical and the size from 3.5cm to 5.5cm(average 4.2 cm) in largest diameter. On postcontrast CT scan, all nodules showed enhancement and four cases showed central low density components. Two nodules contained air within the nodule. In four cases, pleural changes such as effusion and/or focal thickening were noted. No lymphadenopathy was found in all cases. Pathologically, the enhancing portion on CT showed findings of organizing pneumonia such as granulation tissue with fibroblast proliferation in alveolar space and interstitial thickening. The central low density areas on CT were due to ischemic necrosis, abscess and exudate, transudate and infiltration of foamy histiocyte. The possibility of focal organizing pneumonia should be considered when peripherally located solitary pulmonary nodule had enhancing component with no combined lymphadenopathy on CT scan.

    To evaluate the CT findings of bronchial anthracofibrosis. Fourteen patients with bronchoscopically confirmed anthracofibrosis were involved in this study. CT findings (n=3D12) were retrospectively analysed; the pattern, distri-bution and extent of bronchial and parenchymal abnormalities and additional findings such as mediastinal lymphadenopathy and pleural effusion were assessed. Age, sex, and occupational and disease history were history were also reviewed. Patients were aged between 63 and 95 (mean, 71.3) years, and ten were female. Only one patient had an occupational history, but four had a history of pulmonary tuberculosis. Frequent radiologic findings were bronchial wall thickening(n=3D6), atelectasis(n=3D8), mediastinal lymphad-enopathy(n=3D7) and mass(n=3D4). Other accompanying findings were bronchial wall calcification(n=3D3), consolidation(n=3D2) and pleural effusion(n=3D2). Right upper (n=3D7) and right middle lobe(n=3D7) were the most commonly involved sites, and multifocal involvement (n=3D7) was frequent. Bronchial wall thickening, atelectasis and mediastinal lymphadenopathy were characteristic CT findings of anthracofibrosis. When such findings are noted in older or aged female patients, anthracofibrosis should be included in the differential diagnosis

    Chronic pain is a pervasive condition in adolescence and is associated with significant psychological distress, functional disability, social isolation, and decreased quality of life for a subset of affected youth. There is a paucity of research examining potential resilience factors and adaptive processes in pediatric chronic pain. Benefit finding refers to the process of perceiving positive consequences in the face of adversity. Previous research on benefit finding in pediatric samples (e.g., oncology; acute injury) has yielded inconsistent results. This is the first study to examine this construct in youth with chronic pain. The objective of the current investigation was to extend previous research on benefit finding to adolescents with chronic pain and to assess relationships between benefit finding, internalizing mental health symptoms (i.e., anxiety, depression, and posttraumatic stress disorder [PTSD]), pain outcomes (pain intensity and interference), and quality of life. Psychometrically sound self-report measures of benefit finding, anxiety, depressive, and PTSD symptoms, pain intensity, pain interference, and quality of life were completed by 145 youth (67.4% female, Mage = 13.3 years, SD = 2.6), referred to a tertiary-level chronic pain program. Benefit finding was significantly correlated with internalizing mental health symptoms, pain outcomes, and quality of life. Further, benefit finding significantly predicted children's self-reported pain intensity, pain interference, and quality of life when controlling for age and sex. Findings suggest that benefit finding is associated with internalizing mental health symptoms, pain outcomes, and quality of life in youth with chronic pain. Future research examining this construct is warranted.

    Increasing numbers of conventional X-rays, computed tomography and magnetic resonance imaging in the inpatient, outpatient and scientific routine leads to an increasing number of incidental findings. The correct interpretation of these incidental findings with respect to the relevance and the evaluation concerning further work-up is an important task of radiologists. Description of common incidental findings in musculoskeletal imaging and their clinical classification. A PubMed literature search was performed using the following terms: incidental findings, population-based imaging, musculoskeletal imaging, non-ossifying fibroma, enchondroma, osteodystrophia deformans, chondrosarcoma, fibrous dysplasia, simple bone cyst, unicameral bone cyst, solitary bone cyst, aneurysmal bone cyst, vertebral hemangioma, bone island, osteopoikilosis, Tarlov cyst and diffuse idiopathic skeletal hyperostosis (DISH). Incidental findings are observed in up to 40% of imaging procedures. In up to 6% these incidental findings involve the skeletal system. Common incidental findings are discussed and their clinical relevance is explained. (orig.) [de

    Lightweight bug finders (also known as code scanners) are becoming popular, they scale well and can find simple yet common programming errors. It is now considered a good practice to integrate these tools as part of your development process. The Linux project, for instance, has an automated testing...... service, known as the Kbuild robot, that runs a few of these code scanners. In this project, I have carefully studied tens of historical Linux bugs, and I have found that many of these bugs, despite being conceptually simple, were not caught by any code scanning tool. The reason is that, by design, code...... scanners will find mostly superficial errors. Thus, when bugs span multiple functions, even if simple, they become undetectable by most code scanners. The studied set of historical bugs contained many of such cases. This PhD thesis proposes a bug-finding technique that is both lightweight and capable...

    1992-01-01

    Though the context may vary, the topic of the day in the oil and gas industry is ''finding costs per barrel.'' First, there have been numerous articles in both the popular media and the industry press that have argued it is cheaper for companies to buy reserves that find them with the drill bit. Financial analysts have emphasized the importance of comparing relative finding costs when evaluating different companies. The success of failure of a company's management has been judged on the basis of finding costs. In discussing oil and gas prices, economists commonly refer to the relationship between the market prices of oil and gas and their finding costs, and no discussion of the U.S. petroleum industry and the development of a national energy policy is complete without reference to finding costs.

    The aim of this study was to evaluate CT and MRI findings in xanthogranulomatous cholecystitis (XGC) and to correlate the imaging findings with various pathologic parameters. The study included 13 patients with histopathologically confirmed XGC. The CT (n=13) and MRI (n=5) obtained in these patients were evaluated retrospectively. On CT, low-attenuation areas in the wall of XGC correlated with foam and inflammatory cells or necrosis and/or abscess in XGC. Areas of iso- to slightly high signal intensity on T2-weighted images, showing slight enhancement at early phase and strong enhancement at last phase on dynamic study, corresponded with areas of abundant xanthogranulomas. Areas with very high signal intensity on T2-weighted images without enhancement corresponded with necrosis and/or abscesses. Luminal surface enhancement (LSE) of gallbladder wall represented preservation of the epithelial layer. The early-enhanced areas of the liver bed on dynamic CT and MR images corresponded with accumulation of inflammatory cells and abundant fibrosis. Our results indicate that CT and MRI findings correlate well with the histopathologic findings of XGC.

    Hepatic encephalopathy occurs in patients with chronic hepatic insufficiency and can produce abnormalities in the central nervous system, which can be observed in MRI studies. Traditionally, these imaging findings include symmetrical hyper intensities in T1-weighted sequences in the basal ganglia (mainly globus pallidus), involving also the substantia nigra, mesencephalic tegmentum, frontal and occipital cortex. These areas appear of normal intensity in T2-weighted imaging sequences. Other entities that can lead to similar findings include manganese intoxication and type-1 neurofibromatosis. Currently, with the advent of MR spectroscopy, abnormalities in patients with clinical and subclinical hepatic encephalopathy have been described. After hepatic transplantation, hyper intensities of the basal ganglia and the MR spectroscopic findings may disappear within 3 months to 1 year, suggesting a functional, more than a structural damage. This article will demonstrate the MR findings of patients with hepatic encephalopathy due to chronic hepatic insufficiency.

  16. Metasynthesis findings: potential versus reality.

    2014-11-01

    Early on, qualitative researchers predicted that metasynthesis research had the potential to significantly push knowledge development forward. More recently, scholars have questioned whether this is actually occurring. To examine this concern, a randomly selected sample of metasynthesis articles was systematically reviewed to identify the types of findings that have been produced. Based on this systematic examination, it appears that findings from metasynthesis investigations might not be reaching their full potential. Metasynthesis investigations frequently result in isolated findings rather than findings in relationship, and opportunities to generate research hypotheses and theoretical models are not always fully realized. With this in mind, methods for moving metasynthesis findings into relationship are discussed. © The Author(s) 2014.

    The various pathologic conditions detected at CT and MRI and subsumed by the term 'sacral tumor' include primary bone tumors, sacral canal tumors and metastases. Among these, metastases are much more common than primary bone tumors, of which chordoma is the most common. Although the imaging findings of sacral tumors are nonspecific, a patient's age and sex, and specific findings such as calcification or fluid-fluid levels, can help radiologists in their differential diagnosis. We describe the imaging findings of primary sacral tumors, emphasizing the MRI findings

    CT diagnosis of infantile epilepsy was evaluated. High incidence of abnormal CT findings in infantile spasms and Lennox-Gastaut syndrome was same as in other reports. Comparison between CT findings and neurological complications and that between CT findings and electroencephalogram findings revealed a stronger relationship existing in the former. This suggested that CT is more useful as a measure to detect underlying diseases which are due to organic change of the brain to cause epilepsy, rather than as that to disclose epileptic primary lesions of functional change.

    Greater trochanter pain syndrome due to tendinopathy or bursitis is a common cause of hip pain. The previously reported magnetic resonance (MR) findings of trochanteric tendinopathy and bursitis are peritrochanteric fluid and abductor tendon abnormality. We have often noted peritrochanteric high T2 signal in patients without trochanteric symptoms. The purpose of this study was to determine whether the MR findings of peritrochanteric fluid or hip abductor tendon pathology correlate with trochanteric pain. We retrospectively reviewed 131 consecutive MR examinations of the pelvis (256 hips) for T2 peritrochanteric signal and abductor tendon abnormalities without knowledge of the clinical symptoms. Any T2 peritrochanteric abnormality was characterized by size as tiny, small, medium, or large; by morphology as feathery, crescentic, or round; and by location as bursal or intratendinous. The clinical symptoms of hip pain and trochanteric pain were compared to the MR findings on coronal, sagittal, and axial T2 sequences using chi-square or Fisher's exact test with significance assigned as p<0.05. Clinical symptoms of trochanteric pain syndrome were present in only 16 of the 256 hips. All 16 hips with trochanteric pain and 212 (88%) of 240 without trochanteric pain had peritrochanteric abnormalities (p=0.15). Eighty-eight percent of hips with trochanteric symptoms had gluteus tendinopathy while 50% of those without symptoms had such findings (p=0.004). Other than tendinopathy, there was no statistically significant difference between hips with or without trochanteric symptoms and the presence of peritrochanteric T2 abnormality, its size or shape, and the presence of gluteus medius or minimus partial thickness tears. Patients with trochanteric pain syndrome always have peritrochanteric T2 abnormalities and are significantly more likely to have abductor tendinopathy on magnetic resonance imaging (MRI). However, although the absence of peritrochanteric T2 MR abnormalities

    2012-02-01

    Cardiac computed tomography (CT) has evolved into an effective imaging technique for the evaluation of coronary artery disease in selected patients. Two distinct advantages over other noninvasive cardiac imaging methods include its ability to directly evaluate the coronary arteries and to provide a unique opportunity to evaluate for alternative diagnoses by assessing the extracardiac structures, such as the lungs and mediastinum, particularly in patients presenting with the chief symptom of acute chest pain. Some centers reconstruct a small field of view (FOV) cropped around the heart but a full FOV (from skin to skin in the area irradiated) is obtainable in the raw data of every scan so that clinically relevant noncardiac findings are identifiable. Debate in the scientific community has centered on the necessity for this large FOV. A review of noncardiac structures provides the opportunity to make alternative diagnoses that may account for the patient\\'s presentation or to detect important but clinically silent problems such as lung cancer. Critics argue that the yield of biopsy-proven cancers is low and that the follow-up of incidental noncardiac findings is expensive, resulting in increased radiation exposure and possibly unnecessary further testing. In this 2-part review we outline the issues surrounding the concept of the noncardiac read, looking for noncardiac findings on cardiac CT. Part I focused on the pros and cons for and against the practice of identifying noncardiac findings on cardiac CT. Part II illustrates the imaging spectrum of cardiac CT appearances of benign and malignant noncardiac pathology.

    Full Text Available The prevalence of Epstein-Barr virus (EBV in patients with classical Hodgkin’s lymphoma (CHL is geographically variable. In the present study the prevalence of EBV in CHL was assessed in adult patients from Ceará, Brazil. Thirty-seven cases were immunohistochemically evaluated for EBV using latent membrane protein (LMP1 antibody and for EBV latency-associated RNA (EBER1 using in situ hybridization (ISH. Sex and age did not differ among patients as to the frequency of CHL. Nodular sclerosis was the predominant histological subtype. LMP1 was found in Reed-Sternberg cells in 67.5% of the cases whereas ISH detected EBER1 in 75.6%. Regarding histological subtypes EBV infection rates were not found statistically different in nodular sclerosis (NS and mixed cellularity (MC subtypes (p = 0.66.A freqüência do vírus Epstein-Barr (EBV em pacientes com linfoma de Hodgkin Clássico (LHC sofre variabilidade geográfica.

    The defectography is an examination of the anorectal function in defecatory disorder. The defecography has a diagnostic impact on disease, which only emerge during defecation as intussusception, enterocele, prolapse or sphincter dysfunction. Other findings as rectocele or descending pelvic floor are ambiguous concerning clinical relevance. The interpretation of defecography should include patient's history and clinical findings and - if available -endoscopic and manometric findings. (orig.) [de

    The aim of this study was to evaluate the hemodynamics of gastric varices. We evaluated the detection rates of gastric varices, inflowing vessels to gastric varices, and outflowing vessels from gastric varices in 24 patients with gastric varices, using color Doppler sonography, and compared these findings with computed tomography findings. Eighteen patients had F2-type varices and 6 had F3-type, classified according to the Japanese Research Society for Portal Hypertension. Fourteen patients had fundal varices, and 10 had cardiac and fundal varices. The detection rates of collateral veins using color Doppler sonography were as follows: gastric varices were detected in all 24 patients (100%); inflowing vessels, in 21 of the 24 patients (87.5%); and outflowing vessels, in 18 of the 24 patients (75.0%). The detection rates of collateral veins, using computed tomography, were: gastric varices were detected in all 24 patients (100%); inflowing vessels, in all 24 patients (100%); and outflowing vessles, in 21 of the 24 patients (87.5%). The color Doppler findings agreed perfectly with the computed tomography findings in 13 of the 24 patients (54.2%). Although color Doppler sonography is a useful, noninvasive modality for evaluating the hemodynamics of gastric varices, it falls short in visualizing the detailed hemodynamics of the inflowing and outflowing vessels of gastric varices in half of the patients when compared with computed tomography.

    To evaluate the characteristic CT findings of neuroblastoma, we studied neuroblastomas. We analysed CT findings of available 25 cases among pathologically proved 51 neuroblastomas from Jan. 1983 to Sept. 1990. The most frequent site of origin is adrenal gland (40%) and the second is retroperitoneum (32%) and the third ismediastinum (16%). Characteristic CT findings are as follows: Calcifications within the tumor is detected in 86% of abdominal neuroblastomas and 50% of mediastinal origin. Hemorrhagic and necrotic changes within the tumor is noted at 86% in the tumor of abdominal origin and 25% in mediastinal neuroblastomas. Contrast enhanced study showed frequently seperated enhanced appearance with/without solid contrast enhancement. Encasements of major great vessels such as aorta and IVC with/without displacement by metastatic lymph nodes or tumor are frequently seen in 90% of abdominal neuroblastomas. Multiple lymphadenopathy are detected in 95% of abdominal neuroblastomas and 25% of mediastinal neuroblastomas. The most common organ or contiguous direct invasion is kidney in 6 cases and the next one is liver but intraspinal canal invasion is also noted in 2 cases. We concluded that diagnosis of neuroblastoma would be easily obtained in masses of pediatric group from recognition of above characteristic findings

    We evaluate the morphology of the carotid plaque using echogram, CT scan and MRI and compare those neuroradiological findings with histological findings of the plaque. We evaluated 14 cases operated with carotid endoarterectomy for carotid stenosis. We estimated the findings of the echogram, enhanced CT scan and black blood MRI (BB MRI), in comparison with the histological findings of the carotid plaque. Echogram, enhanced CT scan and MRI clearly demonstrated the plaque in cervical carotid stenosis. In most cases, echograms could show the plaque, but in some cases could not due to the back shadow caused by plaque calcification. Enhanced CT scan clearly demonstrated the calcification and the neovasculization in plaque. BB MRI clearly showed the carotid plaque. Low-intensity lesions in T1 and T2 weighted images showed hard and fibrous plaque. High-intensity lesions in T1 and T2 weighted images showed soft plaque with lipoprotein and/or hemorrhage. This study demonstrates the potential of a systemic approach to atherosclerotic plaque with enhanced CT scan and BB MRI compared with histological findings of the carotid plaque. These estimations elucidate the growth mechanism of carotid plaque. (author)

    Background: Transient imaging abnormalities, including changes on diffusion-weighted imaging (DWI), may be seen in status epilepticus. These abnormalities can be followed by hippocampal sclerosis. Case Report: We report a 15-year-old lady with focal non convulsive status epilepticus (NCSE) and focal slowing on EEG. DWI exhibited abnormal hyperintense signals in bilateral temporal and insular cortices. After 3 weeks, MRI performed a localized hippocampal atrophy. Conclusion: The MRI findings indicated vasogenic and cytotoxic edema during seizure activity and subsequent loss of brain parenchyma. (author)

    The importance of finding and development costs in the petroleum industry and the issue of how they can be either manipulated or misunderstood was discussed. Finding and development costs are usually expressed in terms of $/BOE (barrel of oil equivalents) and reflect the total capital expenditures divided by the total reserves replaced and added. Various examples of the importance of finding and development costs in making investment decisions were used to illustrate the effects of potential bias by the resource company, and the need for care and understanding of what the numbers issued by the company actually mean. In general, low and consistent finding and development costs, combined with good netbacks, are the key to value added for shareholders. tabs

    recognition of the clinical and social effects of cognitive impairment. Social, bioethical, and financial issues as well as advance directives should be addressed. A plethora of evidence-based guidelines should be compiled into an internationally agreed guideline of best practice. The multidisciplinary team has changed the history of disease, with still no curative therapy available.A esclerose lateral amiotrófica (ELA é doença neurodegenerativa comprometendo o sistema nervoso motor. Ela causa comprometimento físico, progressivo e acumulativo, com óbito freqüentemente decorrente de falência respiratória. A enfermidade apresenta características diversas nas formas de apresentação, curso e progressão. Não entendemos ainda a causa ou causas dessa enfermidade, nem os mecanismos que regem a sua progressão; assim, tratamentos efetivos não são, até o momento, conhecidos. Atualmente, recomenda-se que os pacientes com ELA sejam tratados com equipe multidisciplinar. Embora ELA e suas variantes sejam reconhecidas por neurologistas, cerca de 10% dos pacientes são mal diagnosticados, e a demora para a confirmação diagnóstica não é incomum. Diagnóstico precoce, informação do diagnóstico com honestidade e sensibilidade, envolvimento do paciente e sua família, e um plano de atenção terapêutica positivo são pré-requisitos essenciais para um melhor resultado clínico e fim terapêutico. Tratamento multidisciplinar e cuidados paliativos podem prolongar a sobrevida e manter melhores aspectos de qualidade de vida. Tratamento com Riluzol aumenta a sobrevida, mas sem alteração na deterioração funcional, enquanto que ventilação não-invasiva prolonga a sobrevida e aumenta ou mantém qualidade de vida. Nesta revisão, nós discutimos o diagnóstico, envolvimento e formas de lidar com dificuldades de funcionamento e de fim de vida, baseando-se na nossa experiência, nos pareceres de peritos, em guias de medicina baseada em evidências científicas, e nos ensaios

    Morphologic renal magnetic resonance imaging (MRI) findings in patients with nephropathia epidemica (NE) were evaluated, and these findings were correlated with the clinical course of NE. Renal MRI was performed in 20 hospitalized NE patients during the acute phase of their disease. A repeat MRI study was made 5-8 months later. Renal parenchymal volume, renal length and parenchymal thickness were decreased in all patients in the repeat study. Edema/fluid collections were found bilaterally in 16 patients in the primary MRI study. Greater change in parenchymal volume, renal length and parenchymal thickness between the primary and the repeat MRI study as well as the presence of edema/fluid collections in the primary study evinced mild association with clinical fluid volume overload, high blood pressure level, inflammation, thrombocytopenia and severe clinical renal insufficiency. Change in parenchymal volume was associated with a severe clinical course more markedly than the other MRI findings. Measurable renal MRI changes occurred in every NE patient. The severity of the findings in MRI evinced mild association with clinical fluid volume overload, high blood pressure level, inflammation, thrombocytopenia and severe clinical renal insufficiency. Based on this study and our previous ultrasound (US) findings, we prefer US as the primary examination mode in NE patients. (orig.)

    To define the imaging patterns of xanthogranulomatous pyelonephritis (XGP). The demographic, clinical, and imaging findings of 21 cases of pathologically proven XGP in 20 patients (bilateral in one) were evaluated. The findings of ultrasonography and CT were retrospectively evaluated with regard to distribution and extent of the disease, kidney size, the presence of calculi, hydronephrosis, and renal function. The findings were assessed by two radiologists, who established a consensus. Imaging and pathologic findings were compared. Sixteen of the 20 patients were female, and 19 were adults. Their age ranged from 3 to 16 (mean, 45) years. In all patients except one, the disease was unilateral (right: left =3D 13 :16). In one patient, XGP was bilateral, and there were thus 21 cases. Seventeen (81%) of these were diffuse, and four (19%) were focal; extrarenal extension occurred in 13 cases (62%), among which ipsilateral pleural effusion was noted in two. The kidney was enlarged diffusely in 12 cases (57%), and focally in three (14%); urinary calculi were present in 16 cases (76%), with staghorn calculi in four of these; and hydronephrosis occurred in 17 (81%). Impairment of ipsilateral renal function was noted in 13 cases (62%). Clinical findings of inflammation such as fever, pyuria, bacteriuria, or leucocytosis were noted in all patients. In addition to nephromegaly, renal function impairment, and urinary obstruction due to calculi, which are typical features of XGP, the condition may also show variable imaging findings. If the images obtained in the case of a middle-aged woman with clinical findings of urinary infection are atypical, we believe that XGP should be included in the differential diagnosis. (author)

    Aim: To evaluate the accuracy of magnetic resonance imaging (MRI) findings in chronic lateral ankle ligament injury in comparison with that of surgical findings. Materials and methods: Forty-eight cases (25 men, 23 women, mean age 36 years) of clinically suspected chronic ankle ligament injury underwent MRI studies and surgery. Sagittal, coronal, and axial, T1-weighted, spin-echo, proton density and T2-weighted, fast spin-echo images with fat saturation were obtained in all patients. MRI examinations were read in consensus by two fellowship-trained academic musculoskeletal radiologists who evaluated the lateral ankle ligaments, including the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) without clinical information. The results of the MRI studies were then compared with the surgical findings. Results: The MRI findings of ATFL injury showed a sensitivity of detection of complete tears of 75% and specificity of 86%. The sensitivity of detection of partial tears was 75% and the specificity was 78%. The sensitivity of detection of sprains was 44% and the specificity was 88%. Regarding the MRI findings of CFL injury, the sensitivity of detection of complete tears was 50% and the specificity was 98%. The sensitivity of detection of partial tear was 83% and the specificity was 93%. The sensitivity of detection of sprains was 100% and the specificity was 90%. Regarding the ATFL, the accuracies of detection were 88, 58, 77, and 85% for no injury, sprain, partial tear, and complete tear, respectively, and for the CFL the accuracies of detection were 90, 90, 92, and 96% for no injury, sprain, partial tear, and complete tear, respectively. Conclusions: The diagnosis of a complete tear of the ATFL on MRI is more sensitive than the diagnosis of a complete tear of the CFL. MRI findings of CFL injury are diagnostically specific but are not sensitive. However, only normal findings and complete tears were statistically significant between ATFL and CFL (p

One underwent follow-up HRCT scanning. Twenty-three(88.5%) of the 26 patients showed abnormal findings. All 23 had lung parenchymal lesions; a small amount of pleural effusion was seen in 11 patients, and lymphadenopathy in six. The predominant parenchymal lesion was thickening of interlobular septae and the axial and intralobular interstitium (n=16). Most lesions were located in both lower lung zones. Other findings were ground-glass attenuation (n=11) and focal parenchymal consolidation (n=8). In one patient, parenchymal lesions were resolved on follow-up HRCT scanning. HRCT findings of interstitial thickening, abnormally increased parenchymal attenuation, pleural effusion and lymphadenopathy with typical clinical symptoms were diagnostic of scrub typhus

    Pediatric CT findings of acute appendicitis were reviewed retrospectively. The subjects were 29 patients (15 boys and 14 girls with an average age of 8.2 years), consisting of 17 with necrotic, 8 with phlegmonous inflammatory, and 4 with catarrhal appendicitis. CT findings were compared with the degree of inflammation. CT revealed abscess in 64.7%, 12.5%, and 0% for necrotic, phlegmonous inflammatory, and catarrhal types, respectively, and 41.4% for all types. An enlarged appendicitis was shown on CT in 86.2% (25/29). Fecalithes were shown on CT in 67.7% (19/29), which was associated with necrotic and phlegmonous inflammatory types, but not with catarrhal type. The other CT findings included thickened paramesocolon of the right lower abdomen, undefined wall of the inner side of the cecum. Inflammation was relatively slight in cases of catarrhal appendicitis, Nine patients less than 5 years of age had phlegmonous inflammatory or necrotic appendicitis. CT allowed definitive diagnosis of appendicitis in 2 of 3 patients with necrotic type. Ct was considered to be very useful in the diagnosis of appendicitis. (N.K.)

    To determine which CT findings are useful for the early disgnosis of esophageal perforation, and on the basis of these findings, to assess the accuracy of prediction of the perforation site. A review of medical records indicated that between January 1995 and December 2001, 36 patients with esophageal perforation were admitted to our hospital. Thirteen of these [M:F=8:5, age; 28-69 (mean, 52.4) years], who had undergone CT chest scanning, were included in this study. The causes of esophageal perforation were trauma (n=5), infectious diseases (n=4), Boerhaave syndrome (n=1), lung cancer (n=1), esophageal cancer (n=1), and idiopathic. Two chest radiologists unaware of the clinical findings reviewed the CT scans and predicted whether the upper or lower esophagus was perforated. The most common CT finding was extraluminal air at the posterior mediastinum (n=11), while other findings included pulmonary consolidation (n=10), pleural effusion (n=7), discontinuity of the esophageal wall (n=6) and subcutaneous emphysema (n=4), fluid collection around the esophagus (n-4), esophageal wall thickening (n=4), pneumothorax (n=2), and lung abscess (n=2). The perforation site was accurately predicted in 76.9% of cases (10/13). The CT findings which help the diagnosis of esophageal perforation, and prediction of the sites at which it occurs, are extraluminal air of fluid collection, focal defect of the esophageal wall, and esophageal wall thickening.

    The describe the radiologic findings of granulomatous mastitis of the breast. This study included 19 patients (age range: 22 to 56 years; mean 37 years) with 22 lesions that were pathologically confirmed as having granulomatous mastitis. All the patients underwent a breast ultrasonography and 13 patients underwent a mammography. The results of the mammography revealed focal asymmetry (n = 9), multiple ill-defined isodense nodules (n 2), ill-defined nodular density on craniocaudal view (n = 1), and unremarkable finding (n = 1). The sonographic findings included continuous or discontinuous multiple tubular and nodular low echoic lesions (n = 7), ill-defined heterogeneously low echoic lesion (n = 5), irregular-shaped, ill-defined low echoic mass (n = 4), fluid collection with internal floating materials suggesting the presence of an abscess (n = 4), ill-defined heterogeneously low echoic lesion and abscess (n = 1), and multiple ill-defined nodules (n = 1). In the case of granulomatous mastitis, the mammography results indicate a lack of specificity between normal findings and focal asymmetry. The sonographic findings indicate that ill-defined heterogeneously low echoic lesions or irregular shaped, ill-defined low echoic masses are difficult to differentiate from breast cancer. The sonographic findings of abscesses indicate a difficulty in differentiating them from cases of pyogenic mastitis. However, multiple tubular and nodular low echoic lesions, especially with a continuous appearance, should point to granulomatous mastitis, and is helpful in its differential diagnosis and treatment.

    The purposes of our study were to find out characteristic ultrasonographic findings of gynecomastia and to analyze age distribution, causative factors of gynecomastia. For these purposes, medical records of 39 male patients with gynecomastia were reviewed and sonographic findings of 13 cases of gentamycin were analyzed. Gynecomastia was found most commonly in teenagers and commonly in twenties. Almostly, it occurred without any evident etiology and classified as idiopathic or pirbuterol type. Less frequently, it occurred due to drug administration, systemic disease, or male hormone deficiency. Unilateral involvement was seen in 29 cases; 17cases involving the left and 12 cases the right. Bilateral involvement was seen in 10 cases. Sonographically,gynecomastia appeared as hypoechoic or intermediate echoic mass with various shape in the subareolar area. One case showed diffuse fatty breast pattern without definable mass. On sonographic evaluation, prominent nipple should not be misinterpreted as a breast mass. For the correct diagnosis of gynecomastia, both side breasts should be evaluated for comparison

  15. Dermoscopy Findings of Hidroacanthoma Simplex

    Full Text Available Hidroacanthoma simplex (HAS, also known as intraepidermal eccrine poroma, is a rare eccrine adnexal tumor that tends to be misdiagnosed as other types of benign skin tumor, including clonal seborrheic keratosis. Notably, HAS is sometimes misdiagnosed and treated by cryosurgery as seborrheic keratosis, which could trigger the later development of porocarcinoma. Therefore, accurate diagnosis of HAS is indispensable for dermatologists to avoid the development of malignant tumors by an unsuitable treatment. In this report, we present the characteristic dermoscopy findings of HAS. Indeed, the dermoscopy findings might be related to the melanin-rich necrotic cells in the epidermis, which are quite different from dermoscopy findings of clonal seborrheic keratosis. As a previous report suggested, it is difficult for a dermatologist to differentiate HAS from clonal seborrheic keratosis by the naked eye. Our findings might be supportive for the early diagnosis of HAS.

    The herniated nucleus pulposus (HNP) is a major cause of low back pain and sciatica. High resolution computed tomography is the most accurate diagnostic tool to define a HNP, because it provides a complete in vivo analysis of bony framework of lumbar spine as well as the supporting soft tissue structures and neural elements. But the discrepancy between neurologic findings and CT findings is often confusing. From May 1983 to August 1986, sixty patients with HNP who had both CT and surgical intervention at Pusan National University Hospital were analyzed. The feasibility of the neurologic examination on HNP and the effect of HNP on nerve root were evaluated on the basis of CT findings. The results were as follows : 1. Thirty-four cases (56.7%) of clinical impression were matched to CT findings in determining level of HNP and affected nerve root. 2. In evaluation of affected level, there was high trend to cause discrepancy between neurologic findings and CT findings in multiple disc involvement than in single involvement. 3. There was no correlation between degree of nerve root compression determined by CT and pattern of neurologic signs (motor weakness, sensory deficit, and reflex change)

    We retrospectively evaluated the characteristic computed tomographic(CT) findings in nine patients with exohepatic hepatocellular carcinoma(HCC) pathologically prove by surgery(n=2) or percutaneous needle biopsy(n=7). The CT findings of exphepatic HCC were correlated with clinical findings and compared with those of usual HCC. Lesions were in the left lobe(n=7) and right lobe(n=2) of the liver. All lesions showed a well-marginated hypodense mass with capsular enhancement on enhanced CT scan. The patterns of capsular enhancement were complete in five and partial in four case. The portal vein thrombosis was seen only in one case. There was no difference between exohepatic HCC and usual HCC in clinical findings such as increased {alpha}-fetoprotein({alpha}-FP), positive hepatitis B surface antigen(HBsAg), and underlying liver cirrhosis. In conclusion, the CT findings of exohepatic HCC were a well-defined hyperdense mass with complete or partial capsular enhancement and these findings may be useful in differentiation from the tumors of adjacent organs.

    The purpose of this study was to present the time-related imaging findings and correlative pathologic findings of radiofrequency pulse-irradiated regions of the liver. Radiofrequency (RF) ablation was performed in 22 rabbit livers with 15-gauge RF probes inserted percutaneously. Regions were imaged with dual-phase CT at 3 days (n=6), 2 weeks (n=6), 4 weeks (n=6), and 12 weeks (n=4) after RF ablation. At 3 days, the regions showed a two-zone structure on plain CT and peripheral enhancement. The regions presented a three-zone structure on pathological study. Hepatocytes appeared as acidophilic bodies, and nuclei were pyknotic at the inner necrotic zone. The middle whitish zone showed enlarged sinusoids. The marginal zone was a regenerative band. At 2 weeks, the two-zone structure was obscured on unenhanced CT. The region showed a two-zone structure on pathological study. At the inner zone, acidophilic degeneration had progressed, however, cell structure remained. The marginal zone showed fibrous tissue bundles. At 12 weeks, the region was obscured on plain CT. Nuclei and cell structures had disappeared almost completely at the inner zone. Collagen fiber had replaced the marginal zone. Zone structural CT findings reflect the pathological findings and time-related changes after RF ablation. Peripheral enhancement in the arterial phase reflects the granulation tissue layer, and its time-related decrease reflects replacement by fibrous tissue. (author)

    Necrotizing pneumonia causes necrosis of pulmonary parenchyma and may lead to pulmonary gangrene. Prior to the antibiotic era, extensive pulmonary involvement was potentially fatal, but the incidence of necrotizing pneumoniais now less common. On contrast-enhanced CT scans, consolidation with contrast enhancement containing necrotic foci with low attenuation and cavities is characteristic. Radiologic findings do not differ according to the causative organism and in most of cases, specific diagnosis may be impossible. Clinical findings and certain characteristic radiologic findings may be helpful for narrowing the differential diagnosis. We illustrate the clinical and radiologic characteristics of necrotizing pneumonia according to causative bacterial organisms

    Radiographic findings in the sternal abnormalities are often nonspecific, showing appearances from a localized benign lesion to an aggressive lesion as seen with infections and malignant neoplasms. A specific diagnosis of sternal abnormalities can be suggested on the basis of CT and MR characteristics. Familiarity with the presentation and variable appearance of sternal abnormalities may aid the radiologist is suggesting a specific diagnosis. We present among others characteristic radiographic findings of hemangioma, chondrosarcoma, hydatid disease, and SAPHO syndrome. In those cases in which findings are not specific, cross-sectional imaging modalities may help the clinician in their management. (orig.)

    The aim of this study was to describe the magnetic resonance imaging (MRI) features of juvenile psoriatic arthritis (JpsA) in children in order to facilitate early diagnosis and proper management. Two pediatric radiologists retrospectively reviewed in consensus a total of 37 abnormal MRI examinations from 31 pediatric patients (nine boys, 22 girls; age range 1-17 years; mean age 9.4 years) who had a definite diagnosis of JpsA and underwent MRI. Each MRI was evaluated for synovium abnormality (thickening and enhancement), joint effusion (small, moderate, and large), bone marrow abnormality (edema, enhancement, and location of abnormality), soft tissue abnormality (edema, enhancement, atrophy, and fatty infiltration), tendon abnormality (thickening, edema, tendon sheath fluid, and enhancement), and articular abnormality (joint space narrowing and erosion). The distribution of abnormal MRI findings among the six categories for the 37 MRI examinations was evaluated. The number of abnormal MRI findings for each MRI examination was assessed. Age at MRI examination and all six categories of abnormal MRI findings according to gender were evaluated. There were a total 96 abnormal MRI findings noted on 37 abnormal MRI examinations from 31 pediatric patients. The 37 abnormal MRI examinations included MRI of the hand (n=8), knee (n = 8), ankle (n = 5), pelvis (n = 5), temporomandibular joint (n = 4), wrist (n = 3), foot (n = 2), elbow (n = 1), and shoulder (n = 1). Twenty-eight diffuse synovial thickening and/or enhancement were the most common MRI abnormality (29.2%). Joint effusion comprised 22 abnormal MRI findings (22.9%). There were 16 abnormal MRI bone marrow edema and/or enhancement findings (16.7%), and in seven (7.3%) the edema involved non-articular sites. Soft tissue abnormality manifested as edema and/or enhancement constituted 14 abnormal MRI findings (14.5%). There were ten MRI abnormalities (10.4%) involving tendons. Articular abnormality seen as joint space

    To evaluate the MR findings of brain damage in cerebral palised patients and to correlate it with gestational age and the time of damage. A retrospective analysis was performed in 40 patients who underwent MR scanning for evaluation of brain lesion in clinically diagnosed cerebral palsy. Authors classified the patients into two groups as premature and full-term and compared MR findings of the two groups. Abnormal MR findings were noted in 28 cases (70%). Five out of 6 patients who had been born prematurely showed isolate periventricular white matter lesions. Twenty-three out of 34 patients who had been born at full-term showed abnormal MR findings. Of these 23 patients, migration anomalies in 7 patients, isolate periventricular white matter lesions in 3 patients, and other combined periventricular subcortical white matter and deep gray matter lesions in 14 patients were seen. At least, 10 patients(43%) of full term group showed abnormal MRI findings reflecting intrauterine brain damage and all 5 patients of premature group showed isolate periventricular white matter lesions suggesting immaturity of brain. MRI is thought to be very useful in the assessment of brain damage for the patients with cerebral palsy by recognizing the location of the lesion and estimating the time of damage

    The purpose of this study is to determine characteristic CT findings in renal abscess. Twenty cases of renal abscess were retrospectively analyzed for CT findings relating to the shape and extent of the abscess, change of nephrogram, peripheral rim enhancement, wedge-shaped enhancement on delayed scans, enlargement of the kidney involved and associated findings. Seven patients had a renal abscess at the right kidney, nine at the lift kidney and two bilaterally. The abscesses were round in 18 cases and finger-like in two. Rim enhancement around renal abscess was seen in four cases (20%). Changes in the nephrogram around the abscess were seen in 12 cases (60%). In all six patients who had undergone delayed postcontrast scans, wedge-shaped enhancement was shown around the abscess (100%). In the observation of the extent of renal abscesses, 14 cases were within the kidney, six cases extended the beyond renal capsule, and two were loculated in the renal fascia itself. Renal enlargement was seen in nine cases (45%). These results suggest that CT findings such as delayed wedge-shaped enhancement, change of nephrogram, peripheral rim enhancement, renal enlargement, and associated findings are valuable for diagnosis, and that CT also gives information concerning the extent, evolution and complication of a renal abscess

    Sleep electroencephalographic (EEG) and computed tomographic (CT) features were examined in 40 institutionalized severely handicapped persons. Cranial CT appearance fell into five major types: (I) no abnormal findings (n=2), (II) generalized brain atrophy (n=16), (III) diffuse parenchymal disturbance (n=10), (IV) brain malformation (n=4), and (V) localized brain disturbance (n=8). In the I group, one person had normal EEG findings as well, but another person had the presence of focal spikes without spindles on EEG. Five of the II group had no abnormal EEG findings; ten had abnormality in basic waves and/or localized paroxysmal waves; and one had generalized spike-and-slow wave complex. All persons in the III group had flattening or disappearance of spindle waves. In the IV group, two persons with cerebral malformation and one with linear nevus sebaceous syndrome in association with hypoplasia of the cerebral hemisphere had abnormality in basic waves and localized paroxysmal waves. In the remaining one person with deficit of vermis cerebelli, there was no EEG abnormality. Among the last group of persons, there was no EEG abnormality corresponding to CT features. (Namekawa, K)

    Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions

    Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions.

    In 80 cases of focal epilepsy, excluding such cases as late onset after the age of 30 and traumatic or expansive lesions, the epileptogenic foci have been studied by comparing the CT findings with the seizure types and the EEG findings. The results were as follows: (1) Abnormal CT findings were observed in 36% of the patients. (2) These findings were classified into 4 large groups: localized cerebral atrophy, localized low density, localized high density with contrast enhancement and diffuse cerebral atrophy. (3) The incidence of CT abnormality was higher in the cases with continuous and localized EEG abnormality than in the cases with other types of EEG abnormality. In 48% of the cases, the location of the abnormal CT findings coincided with their EEG foci. (4) In the cases of temporal lobe epilepsy without abnormal CT images, the print-out data compared with the bilateral promised temporal regions, before and after contrast enhancement. The EMI-No. of the medial temporal focus increased more than that of the contralateral side in 3 cases out of 4 after contrast-media injection. (5) Moreover, for the purpose of comparing the CT findings on general seizures with those in focal seizures, we have studied 80 cases of general seizures. In the cases of the general seizures, abnormal CT findings were observed in only 16%. These abnormal findings were diffuse in 5 cases, localized in 6 cases, and combined in 3 cases. (author)

    In 14 cases of normal and abnormal thymus proved surgically and histopathologically in korea University Hae Wha Hospital during recent 6 years, the clinical and CT findings were analyzed. 1. Of 14 cases, 2 cases were normal thymus, 5 cases were thymic hyperplasia, 4 cases were benign thymoma, 2 case were malignant thymoma and 1 case was thymic cyst. 2. Of 14 cases, 10 cases were associated with myasthenia gravis, and 7 of these 10 cases were 3rd to 5th decades females. Among 10 cases with myasthenia gravis. 5 cases were thymic hyperplasia, 1 case was benign thymoma, 2 cases were malignant thymoma, and 2 cases were normal thymus. 3. All 5 thymic hyperplasia were associated with myasthenia gravis. CT findings of thymic hyperplasia were normal in 4 cases and increased lobe thickness in 1 case. 4. Of 4 cases of benign thymoma, only 1 case was associated with myasthenia gravis, and all 4 cases were positive findings in CT scan. CT findings of benign thymoma were round or oval soft tissue mass in anterior mediastinum, and 1 case had punctuate calcifications. 5. Of 2 cases of malignant thymoma, all 2 cases were associated with myasthenia gravis and positive findings in CT scan. CT findings of malignant thymoma were anterior mediastinal soft tissue mass with obliteration of the normal fat planes surrounding great vessels. SVC compression, and pleural tumor implants. 6. CT yielded significant diagnostic information of differential diagnosis between thymoma and thymoma hyperplasia in myasthenia gravis patients. Also CT was highly sensitive test in detection of thymoma and determined the extent and invasiveness of thymoma.

    An automated method for finding beam focus errors using an optimization program called COMFORT-PLUS. The steps involved in finding the correction factors using COMFORT-PLUS has been used to find the beam focus errors for two damping rings at the SLAC Linear Collider. The program is to be used as an off-line program to analyze actual measured data for any SLC system. A limitation on the application of this procedure is found to be that it depends on the magnitude of the machine errors. Another is that the program is not totally automated since the user must decide a priori where to look for errors

    We present here the CT findings in 10 patients with Reye syndrome. Acute findings is diffuse cerebral swelling with or without parenchymal low density. The cerebral swelling gradually changed to atrophy. The parenchymal low density predisposes in Lt temporoparietal area. Contrast enhanced CT scan showed no additional finding, except 1 case. The hemorrhagic infarction which has not been reported previously was seen in 1 case and resulted in the most prominent sequela. The sequelae were developed in all atrophic cases. So, the brain CT may be useful in monitoring cerebral swelling, determining treatment plan in acute stage, and in presenting prognosis and sequelae on fellow up CT

    The fungus aspergillus can cause a variety of pulmonary disorders. Aspergilloma is a noninvasive aspergillus colonization of virtually any type of preexisting pulmonary cavity or cystic space. Invasive pulmonary aspergillosis is serious, usually fatal infection in patients being treated with immunosuppressants or who have chronic debilitating disease. Allergic bronchopulmonary aspergillosis is characterized clinically by asthma, blood and sputum eosinophilia and positive immunologic reaction to aspergillus antigen. Awareness of the radiographic and CT findings of pulmonary aspergillosis is important in making the diagnosis of aspergillus-caused pulmonary disorders. In this pictorial essay, we illustrated various radiological findings of pulmonary aspergillosis focused on CT findings correlated with gross pathologic specimens

    Subdural hematomas (SDH) are relatively common and the typical CT findings according to the age of them are well established. The CT findings of 82 patients with SDHs were reviewed and compared with the operative findings. The results were as follow: 1. The most common cause of SDHs was the direct trauma which was noted in 60 cases (73.2%). 2. The atypical CT findings of the mixed density were seen in 19 cases (23.2%), including acute SDH 7 cases (20%), subacute SDH 5 cases (41.7%), and chronic SDH 7 cases (20%). 3. The possible causes of the mixed density in acute SDH were unclotted blood in early stage of hematoma development or serum extruded during the early phase of clot retraction. But the possibility of cerebrospinal fluid within subdural space due to an arachnoid tear could not be excluded. 4. The possible causes of the mixed density in subacute and chronic SDH were serum extruded during the hematoma resolution and rebleeding. 5. Wall enhancement of hematomas was noted in 3 cases (25%) of subacute SDHs and 15 cases (42.9%) of chronic SDHs. 6. Most of SDHs was crescentic in shape, but lenticular in 4 cases (4.9%). Midline shift and compression of ventricles were proportional to the maximum thickness of SDHs. There were seen ipsilateral dilatation of ventricles in 9 cases (11.0%) and brain edema in 11 cases (13.4%)

    Conclusion Association of these findings with an expanded clinical definition of Joubert is warranted. The clinical subtypes of JS may be associated with specific types of mutations in the causative genes. This report, which evaluates the findings in a relatively young cohort, provides a unique opportunity to consider the earliest manifestations of JS that may lead to early recognition and appropriate genetic testing to confirm the diagnosis. Clinical findings beyond those identified in this report and by prior publications should be evaluated as potentially independent of the primary genetic condition rather than assuming that each new finding is part of the same syndrome.

    Struma ovarii is ovarian tumor composed solely or predominantly of thyroid tissue or tumor in which hyperthyroidism results from ovarian thyroid tissue, and usually occurs in tandem with cystic teratoma. Ovarian cystic teratoma is radiologically easily diagnosed due to calcification or fat, for example, but the preoperative diagnosis of struma ovarii is often difficult due to rare characteristic features of thyroid tissue. Our purpose was to determine whether there were specific findings of struma ovarii which distinguished it from other ovarian tumors, and this involved analysis of its radiologic findings. Using ultrasonography, computed tomography, and magnetic resonance imaging, preoperative radiologic findings of pathologically-proven struma ovarii in eleven patients were retrospectively evaluated for site, margin, nature (cystic, solid, mixed), contrast enhancement, septa, mural nodule, calcification, fat, and metastasis. These findings were compared with pathologic findings. All eleven tumors were unilateral, ten had smooth tumor margins, seven were mixed cystic and solid tumors (more than 70% of solid components in one tumor), and nine had regular septa. Three of four cystic masses (one unilocular, one bilocular and two multilocular cysts) had mural nodules. Calcifications were found in two tumors, and fat in one. Malignant change or metastasis was not found in any tumor. In one patient with hyperthyroidism due to struma ovarii, symptoms and signs of this subsided after removal of the tumor on salpingo-oophorectomy. Most cases of struma ovarii occurred unilaterally within ovarian teratomas in premenopausal women, and were mixed cystic and solid masses with smooth margins that are commonly enhanced on contrast enhanced scans. In one patient, hyperthyroidism was caused by struma ovarii. There were, however, no specific radiologic findings that were sufficiently typical to suggest the correct preoperative diagnosis of struma ovarii.

    Early diagnosis of ruptured and unruptured tubal pregnancy became more accurate with the introduction of transvaginal sonographic equipment. The management principle of tubal pregnancy might be changed according to the sonographic findings. The purposes of this study were to define the sonographic findings of tubal pregnancy and to determine whether it is possible to differentiate the unruptured tubal pregnancies from the ruptured ones depending on the sonographic findings. The authors investigated the sonographic findings of the surgically confirmed 25 tubal pregnancy patients. There were 22(88%) unruptured and 3(12%) ruptured tubal pregnancies. Unruptured pregnancies showed tubal ring in 8, well defined hematosalpinx in 11, and poorly defined hematosalpinxin 2 patients. Ruptured pregnancies showed tubal sac with irregular margin in 2, and ill-defined hematosalpinx in one patient. In summary, well marginated tubal ring and hematosalpinx suggested unruptured tubal pregnancy, while tubal sac with irregular margin suggested ruptured pregnancy. However, it was difficult to differentiate the unruptured tubal pregnancy from the ruptured one when hematosalpinx was ill-defined

    Full Text Available Neonates have a poorly developed immune system. Respiratory pathogens cause disease during early periods of live. Consequently, it is important to develop protective vaccines that induce immunity and immunological memory against respiratory pathogens early in life. Intranasal (i.n. route could be an effective via for immunization. Therefore, we explored the effectiveness of AF (Adjuvant Finlay PL1 (Proteoliposome from Neisseria meningitidis serogroup B and its derivate Cochleate (AFCo1 by nasal route in neonatal mice. They were immunized i.n. 3 times 7 days apart and anti PL systemic and mucosal antibody response were measured by ELISA. In addition, a prime-boost strategy was used to evaluate the humoral immune response in neonate mice. The 3 doses of AFPL1 or AFCo1 induced significant levels of anti PL IgG antibodies in comparison whit control, but AFCo1 (2017 U/mL was significantly higher than AFPL1 (1107 U/mL. AFCo1 and AFPL1 induced a predominant Th1 pattern with IgG2a/IgG1 >1 by i.n. immunization and AFCo1 induced a high anti PL IgA saliva response in saliva. Interestingly, one nasally prime at 7 days of born and a memory one boost i.n. dose 9 weeks later with AFCo1 or AFPL1 showed similar specific IgG levels and IgG2a/IgG1 relation than 3 i.n. doses in adult mice. In conclusion, these results represent the first report of neonatal intranasal vaccination using AFCo1 capable to induce systemic and mucosal immunity and priming for memory.

  8. Effective Bug Finding

    Rivas, Iago Abal

    Lightweight bug finders (also known as code scanners) are becoming popular, they scale well and can find simple yet common programming errors. It is now considered a good practice to integrate these tools as part of your development process. The Linux project, for instance, has an automated testing...... service, known as the Kbuild robot, that runs a few of these code scanners. In this project, I have carefully studied tens of historical Linux bugs, and I have found that many of these bugs, despite being conceptually simple, were not caught by any code scanning tool. The reason is that, by design, code...... by matching temporal bug-patterns against the control-flow graph of this program abstraction. I have implemented a proof-of-concept bug finder based on this technique, EBA, and confirmed that it is both scalable and effective at finding bugs. On a benchmark of historical Linux double-lock bugs, EBA was able...

    Incidental extra-mammary findings in breast Magnetic Resonance Imaging (MRI) may be benign in nature, but may also represent a metastasis or another important lesion. We aimed to analyse the prevalence and clinical relevance of these unexpected findings. A retrospective review of 1535 breast MRIs was conducted. Only axial sequences were reassessed. Confirmation examinations were obtained in all cases. 285 patients had a confirmed incidental finding, which were located in the liver (51.9%), lung (11.2%), bone (7%), mediastinal lymph nodes (4.2%) or consisted of pleural/pericardial effusion (15.4%). 20.4% of incidental findings were confirmed to be malignant. Positive predictive value for MRI to detect a metastatic lesion was high if located within the bone (89%), lymph nodes (83%) and lung (59%), while it was low if located within the liver (9%) or if it consisted of pleural/pericardial effusion (6%). The axial enhanced sequence showed superior sensitivity to unenhanced images in detecting metastatic lesions, especially if only smaller ({<=}10 mm.) lesions were considered. The prevalence of metastatic incidental extra-mammary findings is not negligible. Particular attention should be to incidental findings located within the lung, bone and mediastinal lymph nodes.

    This book can serve the reader in three ways: First, it presents normal findings for all radiographic techniques including KM. Important data which are criteria of normal findings are indicated directly in the pictures and are also explained in full text and in summary form. Secondly, it teaches the systematics of interpreting a picture - how to look at it, what structures to regard in what order, and for what to look in particular. Checklists are presented in each case. Thirdly, findings are formulated in accordance with the image analysis procedure. All criteria of normal findings are defined in these formulations, which make them an important didactic element.

    . In this paper we present methods for finding all maximal pairs under various constraints on the gap. In a string of length n we can find all maximal pairs with gap in an upper and lower bounded interval in time O(n log n+z) where z is the number of reported pairs. If the upper bound is removed the time reduces...... to O(n+z). Since a tandem repeat is a pair where the gap is zero, our methods can be seen as a generalization of finding tandem repeats. The running time of our methods equals the running time of well known methods for finding tandem repeats....

    Describe the dynamic CT findings of pulmonary hamartoma and to compare these findings with histopathologic findings. he Institutional Review Board approved this retrospective study and the requirement for patient informed consent was waived. The hemodynamic CT features of 11 patients (M : F = 6 : 5; mean age, 53.6 years) with pathologically proven pulmonary hamartoma were evaluated. All 11 patients underwent enhanced dynamic CT using a helical technique. A series of images were obtained throughout each nodule with 2.5-mm collimation at 0, 30, 60, 90 and 120 seconds and at 4, 5 and 15 minutes after an intravenous injection of contrast medium. Extents and patterns of enhancement were correlated with histologic tumor components. ll 11 tumors showed persistent enhancement with variable degrees of net enhancement [mean tumor peak enhancement, 48.6 ± 19.0 Hounsfield unit (HU); mean tumor net enhancement, 31.9 ± 11.8 HU] and thick capsular and septal enhancement. Histologically, all 11 tumors were composed of mature cartilage and loose mesenchymal tissue. A significant positive correlation was found between the net enhancement values and loose connective tissue component percentages (r = 0.749, p = 0.008); further, a negative correlation was found between the net enhancement values and cartilaginous component percentages (r = -0.813, p = 0.002). n dynamic CT, hamartoma exhibited persistent enhancement without washout as well as thick capsular and septal enhancements. Net enhancement values were found to be positively correlated with the proportion of the loose connective tissue component. Thick capsular and septal enhancements were attributed histopathologically to loose connective tissue, separating tumors into cartilaginous lobules.

    To evaluate the characteristic MRI findings of pubic insufficiency fracture. In nine cases of pubic insufficiency fracture, the findings of plain radiography (n=9), MRI (n=9), and bone scintigraphy (n=8) were reviewed. We retrospectively analyzed, with regard to fracture site, the destructive pattern revealed by plain radiography, and uptake by other pelvic bones, as demonstrated by RI bone scanning. The MR findings evaluated were the fracture gap and its signal intensity, the site and signal intensity of the soft tissue mass, and other pelvic bone fractures. Plain radiography revealed osteolysis and sclerosis of pubic bone in eight of nine cases (89%), and parasymphyseal fractures in seven (78%). RI indicated uptake by the sacrum in six cases (66%), and by the ilium in three (33%). MR findings of fracture gap (seven cases, 78%) were hypo to isointensity on T1WI, hyper intensity on T2WI and the absence of contrast enhancement. Soft tissue masses were found in seven cases (78%); in four of these the location was parasymphyseal, and in three, surrounding muscle was involved. Hypo to isointensity was revealed by T1WI, hyperintensity by T2WI, and there was peripheral enhancement. Other associated pelvic bone fractures involved the sacrum in seven cases and the ilium in four. The characteristic MR findings of pubic insufficiency fracture were parasymphyseal location, fracture gap, peripherally enhanced soft tissue mass formation, and fractures of other pelvic bones, namely the sacrum and ilium

    STUDY DESIGN: A cross-sectional and longitudinal analysis using 2 different data sets OBJECTIVE.: To investigate if the number of different MRI findings present is more strongly associated with low back pain (LBP) than single MRI findings. SUMMARY OF BACKGROUND DATA: Most previous studies have....... The outcome for the cross-sectional study was presence of LBP during the last year. The outcome for the longitudinal study was days to recurrence of activity limiting LBP. In both data sets we created an aggregate score of the number of different MRI findings present in each individual and assessed...... investigated the associations between single MRI findings and back pain rather than investigating combinations of MRI findings. If different individuals have different pathoanatomic sources contributing to their pain, then combinations of MRI findings may be more strongly associated with LBP. METHODS...

    To assess the computed tomography (CT) and magnetic resonance (MR) findings in MELAS syndrome (mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes) and their contribution to the diagnosis of this entity. We present three patients in which a diagnosis of MELAS syndrome was confirmed by muscle biopsy. CT revealed pathological findings in two patients: bilateral calcifications in the basal nuclei in one and low-attenuation lesions in occipital lobes in the other. Initial or follow-up MR demonstrated pathological findings highly suggestive of MELAS syndrome in all the patients. They consisted of hyperintense lesions in T2-weighted images, located predominantly in the cortex of occipital and parietal lobes. Cerebellar atrophy was also observed in two patients. The clinical signs varied, but epileptic seizures, headache, vomiting, ataxia, muscle weakness and pyramidal involvement were among the major ones. Only one patient presented high lactic acid levels, and in two, the initial muscle biopsy was not conclusive enough to provide the definitive diagnosis. CT and, especially, MR are useful tools in the diagnosis of MELAS syndrome, particularly in those cases in which initial negative laboratory and histological results make diagnosis difficult.

    Aim: To investigate the frequency, distribution, and nature of incidental extra-mammary findings detected with breast MRI. Materials and methods: Incidental findings were defined as unexpected lesions outside the breast, not previously known or suspected at the time of referral. Five hundred consecutive breast MRI studies performed from June 2010 to September 2012 were reviewed in this retrospective study for which the institutional review board granted approval and waived the requirement for informed consent. MRI findings were compared with subsequent diagnostic procedures in order to differentiate benign from malignant lesions. Results: One hundred and thirty-eight incidental findings were found in 107 of the 500 (21.4%) examined patients. The most common site was the liver (61/138; 44.2%), followed by the lung (24/138; 17.4%), mediastinum (22/138; 15.9%), pleural cavity (15/138; 10.9%), bone tissue (9/138; 6.5%), spleen (3/138; 2.2%), major pectoral muscle (3/138; 2.2%), and kidney (1/138; 0.7%). Twenty-five of the 138 (18.1%) incidental findings were confirmed to be malignant, whereas the remaining 113 (81.9%) were benign. Malignant findings were exclusively detected in patients with known breast carcinoma, whereas incidental findings in patients without a history of carcinoma were all benign. Twenty-five of 100 (24.8%) incidental findings among patients with history of breast cancer were malignant. Conclusion: Although many of incidental findings were benign, some were malignant, altering the diagnostic work-up, staging, and treatment. Therefore, it is important to assess the entire field of view carefully for abnormalities when reviewing breast MRI studies. - Highlights: • 500 consecutive breast MRI studies were retrospectively reviewed. • Incidental findings were found in 107/500 (21.4%) of examined patients. • Incidental extra-mammary findings on breast MRI are common. • Malignant findings were exclusively detected in patients with known breast

    The problem of attribute reduction is an important problem related to feature selection and knowledge discovery. The problem of finding reducts with minimum cardinality is NP-hard. This paper suggests a new algorithm for finding exact reducts with minimum cardinality. This algorithm transforms the initial table to a decision table of a special kind, apply a set of simplification steps to this table, and use a dynamic programming algorithm to finish the construction of an optimal reduct. I present results of computer experiments for a collection of decision tables from UCIML Repository. For many of the experimented tables, the simplification steps solved the problem.

    The authors made comparative studies of CT findings with upper GI series and surgical findings in 20 cases of histologically proven gastric cancers. The identification of chickening of gastric wall and local and remote metastasis by CT was thought to be great value in treatment planning and prediction of prognosis of the patients. The results were as follows: 1. Of 20 cases, 19 cases demonstrated thickening of gastric wall. Among 3 cases suggested as early cancer on upper GI series, 2 cases demonstrated thickened gastric wall on CT and it was proved to be advanced cancer at surgery. 2. Out of 8 cases showed no definite metastasis on CT, 4 cases had malignant infiltration histologically in the regional lymph nodes. But they were less than 1.5 cm in diameter. 3. The frequency order of remote metastasis found by CT was pancreas, liver, left adrenal gland and lung in organs and retroperitoneal, retrocrural and regional nodes in lymph nodes.

    Fetal magnetic resonance imaging (MRI) is a routinely used tool in prenatal diagnosis; however, there is a lack of studies evaluating incidental findings observed in the mother. This study describes and quantifies incidental findings observed in the mother during fetal MRI. We reviewed all fetal MRI studies at the University of Minnesota Medical Center from February 2008 to September 2014. Two pediatric radiologists retrospectively conducted a consensus evaluation. The maternal findings were categorized into neurologic, gynecologic, urinary, gastrointestinal and musculoskeletal. Hydronephrosis consistent with the stage of pregnancy was recorded but was not included as an abnormal finding. Abnormal findings were classified into three groups, depending on their clinical significance: level I (low), level II (medium) and level III (high). We evaluated 332 pregnant patients with a mean age of 29.3 years and a mean gestational age of 29 weeks. Of these, 55.4% had at least 1 incidental finding, for a total of 262 incidental maternal findings. Of the 262 abnormalities, 113 (43.1%) were neurologic, 69 were gynecologic (26.3%), 36 (13.7%) urinary, 24 (9.2%) gastrointestinal and 20 (7.6%) musculoskeletal. Of the 262 incidental findings, 237 (90.5%) were level I, 24 (9.2%) were level II and 1 (0.4%) was level III. Our results suggest that although the vast majority of incidental maternal findings are benign, more significant findings are still encountered and should be expected. (orig.)

    Background: Diseases exhibiting osteolysis in children are rare hereditary conditions. Several types have been recognised with different clinical manifestations. One type includes subcutaneous nodules, arthropathy and osteolysis and has been termed NAO syndrome. Previous radiological reports have described the affected bones, usually the carpal and tarsal regions, but a detailed analysis of the radiological findings of both the axial as well as the appendicular skeleton has not been reported. Objectives: To describe the radiological findings in a large group of children with an autosomal recessive disease characterized by nodules, familial arthropathy and osteolysis. Materials and methods: The study comprises 14 patients from 9 families and all patients had the triad of nodulosis, arthropathy and osteolysis (NAO). Results: The most common radiological manifestations were osteopenia, undertubulation of long bones, arthritic changes, sclerotic sutures of the calvaria, osteolysis and muscle contractures. Other common findings were squared vertebrae, broad medial clavicles and brachycephaly. Progress of disease was documented in more than half of the patients. Conclusions: Our study is the first report of the detailed radiological findings of NAO syndrome. In NAO syndrome, both the axial and appendicular skeleton are involved (orig.)

    Full Text Available Background: Dermoscopy is an important tool for the diagnosis of pigmented skin lesions. Newly, this method has also been used in the diagnosis and follow-up hair and scalp disorders. Objective: The objective of this study was to investigate dermoscopic findings in a sample of patients with clinical and histopathological compatible with cicatricial alopecia. Methods: Twenty nine patients with cicatricial alopecia diagnosed by clinical and histological findings were examined by dermoscopy.. Results: Dermoscopic features evaluated included folliculitis decalvans (n=8, pseudopelade of Brocq (n=7, lichen planopilaris (n=6, discoid lupus erythematosus (n=2, dissecting cellulitis (n=1, and secondary cicatricial alopecia (n=5. Visualization of structures previously examined with naked eye were seen in great detail with dermoscopy. The loss of follicular orifices was seen in all patients with cicatricial alopecia. Perifollicular scaling, arborizing red lines, honeycomb pigment pattern, white dots and tufted hairs were the other most obvious findings. Conclusion: Use of dermoscopy in the clinical evaluation of cicatrical alopecia improves diagnostic capability beyond simple clinic inspection, but larger studies correlating dermoscopic findings with histopathology exams are needed to improve understanding of this method.

    Abdominal actinomycosis is a chronic, progressive, suppurative disease with a favorable response to intravenous treatment with penicillin. In many instances, however, its clinical and radiological findings may overlap with those of other inflammatory and neoplastic conditions, and the familiarity with the various radiological features can thus avoid diagnostic delays. The purpose of this paper is to describe and discuss the CT findings of abdominal actinomycosis

    A 59-year-old female with carcinoma of the colon and known liver metastatic disease was referred for bone scan to evaluate for bone metastases. Although no bone metastases were found, there was abnormal uptake noted in the liver corresponding to a metastatic calcified lesion. The only other findings were of degenerative disease in the cervical spine, right shoulder and small joints of the hands. A 69-year-old male with carcinoma of the prostate and right side low back pain was referred for bone scan. No focal abnormalities to suggest metastatic disease were identified; findings within the cervical spine, lumber spine and knees were presumed secondary to degenerative disease. Intermittent pain persisted and the patient was referred for a repeat bone scan six months later. Previous scan findings of degenerative disease and no metastatic disease were confirmed; however, closer inspection revealed an enlarged right kidney with significant retention of tracer in the pelvicalyceal system suggesting possible obstruction. A Retrograde pyelogram was performed, and no obvious obstruction demonstrated. As bone scan findings were very suggestive of obstruction, a DTPA scan with lasix was performed showing a dilated right collecting system with no functional obstruction. Given the degree of dilation, it is possible that the patient experiences intermittent PUJ obstruction causing his symptoms. A 33-year-old male with insulin dependent diabetes mellitus and viral arthritis was referred for a bone scan. A three phase revealed increased uptake in the region of the knee and leR proximal tibia. Delayed whole body images revealed multiple focal areas of osteoblastic activity in the leR tibia. Abnormal uptake was also seen in the upper third of the leR femur. The remainder of the skeletal survey was normal. X-ray correlation of the leR tibia and femoral findings was undertaken.

    To evaluate the sonographic findings of the heterotopic pregnancy which is increasing recently. Thirty-nine cases of heterotopic pregnancy after ovulation induction and IVF-ET (In Vitro Fertilization-Embryo Transfer) during the recent 3 years were analyzed. They were diagnosed by ultrasonography and proved surgically afterwards. Sonographic findings were analyzed focusing on gestational week of intrauterine pregnancy and location of ectopic pregnancy. In particular, adnexal mass was evaluated with regard to size and the characteristic findings such as ectopic gestational sac (echogenic ring). Also, overian cyst and fluid collection in cul-de-sac space were reviewed carefully. Heterotopic pregnancy was proved surgically by salpingectomy in 33 cases and by resection of cornus in six cases. Sonographic diagnosis using transvaginal ultrasound was made from five weeks to nine weeks two days (six weeks and four days in average) from last menstral period in all 39 cases. Ectopic pregnancy was identified in ampullary part in 29 cases, in the isthmic portion of tube in four cases and in the cornus of uterus in six cases. The intrauterine pregnancy was diagnosed by identifying the intrauterine gestational saccontaining a yolk sac in seven cases and the embryo with fetal heart beat in the remaining 32 cases. Adnexal masses of heterotopic pregnancy were less than 3 cm in diameter in 2 cases (57%), 3-4 cm in 11 cases (28%) and more than 4 cm in 6 cases (15%). A characteristic finding of ectopic mass was echogenic ring which was visible in 33 (84.6%) cases by transvaginal ultrasound. Six cases had pelvic hematosalpinx and two had pelvic hematoma. Of 10 cases (26%) which were identified to have ovarian hyperstimulation syndrome, eight (21%) had large amount of fluid collection in cul-de-sac and abdomen. Ultrasonographic identification of the intrauterine pregnancy and the ectopic chorion ring is effective for the early diagnosis of the heterotopic pregnancy.

    1987-08-01

    The CT features of 28 patients with ARDS are described. Diffuse lung consolidation, multifocal patchy involvement and lobar or segmental disease were observed. Large lung cysts as well as small cysts producing a 'swiss-cheese' appearance of the parenchyma, were detected. These findings were not regularly appreciated on chest radiographs. The overall mortality of our 28 patients was 72.7% (22 out 28). Patients with lung cysts showed a trend toward higher mortality (87.5% or 13 out 16). Other unexpected findings were basilar lung abscesses and an empyema. In 15 out of 28 patients, CT scans provided additional information, not obvious on bedside chest radiographs and led to a change in management in five patients.

    Highlights: • Various thoracic CT findings, including cysts, mediastinal masses, etc. were found. • Cysts show upper and peripheral dominant distribution. • The number, size, and distribution of the pulmonary cysts in NF-1 revealed significant correlation. • It is suspected that thoracic CT findings in NF-1 occur independently. - Abstract: Purpose: To evaluate the prevalence rates and the correlations of thoracic computed tomography (CT) findings of neurofibromatosis 1 (NF1) in 88 patients. Materials and methods: Chest CT images of 88 NF1 patients were independently reviewed by three observers, and the CT findings were evaluated. If abnormal findings were present, their number, size, and distribution were recorded. The prevalence rate of each CT finding was calculated, and the correlations between CT findings were analyzed. Results: Of the 88 cases, 13 were positive for cysts, 16 for emphysema, 8 for nodules, 8 for GGNs (ground glass nodules), 13 for mediastinal masses, 20 for scoliosis, 44 for subcutaneous nodules, and 34 for skin nodules. Cysts showed upper and peripheral dominant distributions. Regarding 13 mediastinal masses, 2 were diagnosed as malignant peripheral nerve sheath tumors (MPNSTs), 1 was diagnosed as primary lung cancer, 2 were diagnosed as lateral meningocele, 3 were diagnosed as neurofibromas, and the remaining 7 were considered neurofibromas. There was a significant correlation between the prevalence of subcutaneous nodules and that of skin nodules. Significant positive correlations were also seen between size and number, size and rate of central distribution, and number and rate of central distribution of cysts. Conclusion: Various CT findings were found in NF-1 patients, and the prevalence rates of subcutaneous and skin nodules were higher than other findings. Though the prevalence rates of subcutaneous nodules and skin nodules were significantly correlated, the other CT findings in NF-1 occurred independently. The number, size, and

    We wanted to evaluate the imaging findings of fibrous hamartoma of infancy (FHI). We retrospectively reviewed the clinical presentation and the sonographic (n = 5) and CT (n = 3) findings of 5 cases of surgically/pathologically confirmed FHI. The sonographic findings were evaluated according to the location, size, internal echogenicity and vascularity. The CT findings were evaluated according to the attenuation of the mass on both the pre- (n = 3) and postcontrast (n = 2) scans. The image findings were correlated with the pathologic findings. The mean age was 14.8 months (range, 7 months - 3 years). The location of lesions was all in the fatty layer of the back (n = 4) and upper arm (n = 1). All the lesions demonstrated-hypertrichosis on the overlying skin. The lesions measured 31.2 mm in the longest diameter (range: 18 mm - 50 mm). The sonographic findings were purely solid, heterogeneously hyperechoic and hypovacular for all the cases. The internal architecture revealed a 'layering' appearance (n = 3). The CT findings demonstrated isoattenuation, as compared to the adjacent muscle on both the pre- and postcontrast CT scans. The pathologic correlation demonstrated a characteristic 'organoid' mixture of fibrous, mucoid and fatty tissues in all cases. The diagnosis of FHI can be suggested by the sonographic findings of a superficially located, heterogeneous solid mass with a 'layering' appearance in the fatty layer of the back or arms of infants with local hypertrochosis on the overlying skin

    This book gives answers to questions frequently heard especially from trainees and doctors not specialising in the field of radiology: Is that a normal finding? How do I decide? What are the objective criteria? The information presented is three-fold. The normal findings of the usual CT and MRI examinations are shown with high-quality pictures serving as a reference, with inscribed important additional information on measures, angles and other criteria describing the normal conditions. These criteria are further explained and evaluated in accompanying texts which also teach the systematic approach for individual picture analysis, and include a check list of major aspects, as a didactic guide for learning. The book is primarily intended for students, radiographers, radiology trainees and doctors from other medical fields, but radiology specialists will also find useful details of help in special cases.

    2008-01-01

    Full Text Available Multiple sclerosis (MS is a progressively disabling neurological disease which symptoms affect sensory, motor and psychological functioning. Several clinical neurological and psychological variables influence the neuropsychological profile in MS, which is extremely heterogeneous. The main objective of the present study was to investigate if it is possible to statistically stratify control subjects and MS patients from neurological, socio-demographic and neuropsychological dimensions. With this purpose we applied cluster analysis procedures to five neuropsychological instruments selected according to diagnostic accuracy from a pool of 9 neuropsychological tests. The sample was composed of 45 healthy controls and 35 MS patients with similar socio-demographic characteristics. The results indicated an ideal solution with 4 different clusters according to two dimensions: "cognitive" and "psychosocial" functioning, which represent independent but non-disjunctive aspects of neuropsychological functioning in MS.

Follicular bronchiolitis has been associated with viral infection, autoimmune disease and immunodeficiency. The most common clinical manifestation is respiratory distress in infancy followed by a prolonged course with gradual improvement. We found no reports of systematic review of high-resolution computed tomography (HRCT) findings in pediatric follicular bronchiolitis. The purpose of this study was to describe the HRCT findings of follicular bronchiolitis in children and correlate these imaging findings with histopathology. A 5-year retrospective review of all pathology-proven cases of follicular bronchiolitis was performed. Inclusion criteria were age <18 years and an HRCT within 6 months of lung biopsy. HRCTs were reviewed by three observers and scored using the system previously described by Brody et al. Six patients met the inclusion criteria with age range at HRCT of 7-82 months (median: 39.5 months). Pulmonary nodules (n=6) were the most common HRCT finding followed by focal consolidation (n=5), bronchiectasis (n=4) and lymphadenopathy (n=3). Tree and bud opacities and nodules on CT correlated with interstitial lymphocytic infiltrates and discrete lymphoid follicles on pathology. The salient HRCT findings of childhood follicular bronchiolitis are bilateral, lower lung zone predominant pulmonary nodules and bronchiectasis with infantile onset of symptoms. These characteristic HRCT findings help differentiate follicular bronchiolitis from other forms of infantile onset ILD. (orig.)

    To describe the abdominal imaging findings of patients with gastrointestinal Basidiobolus ranarum infection. A literature search was performed to compile the abdominal imaging findings of all reported worldwide cases of gastrointestinal basidiobolomycosis (GIB). In addition, a retrospective review at our institution was performed to identify GIB cases that had imaging findings. A radiologist aware of the diagnosis reviewed the imaging findings in detail. Additional information was obtained from the medical records. A total of 73 GIB cases have been published in the medical literature. The most common abdominal imaging findings were masses in the colon, the liver, or multiple sites and bowel wall thickening. Initially, many patients were considered to have either a neoplasm or Crohn disease. We identified 7 proven cases of GIB at our institution, of which 4 had imaging studies (4 computed tomography [CT] examinations, 4 abdominal radiographs, and an upper gastrointestinal study). Imaging studies showed abnormalities in all 4 cases. Three-fourths of our study patients had an abdominal mass at CT. Two of 3 masses involved the kidneys and included urinary obstruction. All masses showed an inflammatory component with adjacent soft tissue stranding, with or without abscess formation. Radiologists should consider GIB when a patient from an arid climate presents with abdominal pain, weight loss, and an inflammatory abdominal mass on CT. Abdominal masses of the colon or liver, bowel wall thickening, and abscesses are the most common imaging findings.

    Background. Toddlers with severe physiologic tibial bowing are considered to be at risk for the development of Blount's disease. Objective. To correlate MR findings of the knee with the clinical outcome in toddlers with severe physiological tibial bowing. Materials and methods. MR findings were evaluated in 22 affected legs of 14 children with severe tibial bowing (mean age 1.9 years). In 18 affected legs, MR findings were compared with the transition of the tibial metaphyseal-diaphyseal angle (MDA) and tibiofemoral angle (TFA) measured serially between 2 and 3 years of age. Results. MR findings of severe tibial bowing comprised undulation of the posteromedial physis of the tibia (3/22), signal alterations in the medial tibial metaphysis (10/22), T2 prolongation in the posteromedial tibial epiphyseal cartilage (14/22) and signal changes in the medial menisci (18/22). The decrease in the TFA was different in the legs with and without increased signal in the epiphyseal cartilage, and the decrease in the MDA was different in the legs with and without physeal undulation. Conclusion. MR imaging findings can predict the retarded resolution of tibial bowing, which may be a risk factor for the development of Blount's disease. (orig.)

    Twenty-nine patients with orbital inflammatory disease (OIDs) were retrospectively reviewed in order to analyze detailed CT findings which might aid in differentiating OIDs. This study comprised 18 pseudotumors, 5 thyroid ophthalmopathies, and 6 cases of orbital cellulitis. CT scans of the pseudotumors showed various findings such as exophthalmos, scleritis, myositis of the extraocular muscle (MOM), and bone lesion. Bone lesions of the pseudo tumors, which have been rarely reported, were present in 7 cases in our series. Bilateral exophthalmos, myositis, and retrobulbar fat deposition were readily detected by CT in thyroid ophthalmopathy, and, in addition, we found bone erosions involving the orbital apices in 2 cases. In orbital cellulitis, extraorbital soft tissue swelling and lateral displacement of the medial rectus muscle in cases with ethmoiditis were the most conspicuous features. In summary, because of the overlapping CT findings in OIDs, careful examination of CT findings regarding the mode of EOM involvement and the presence or absence of scleritis or sinusitis might help narrow down the differential diagnosis. A pseudotumor with bone lesions could be mistaken as a malignant lesion, and therefore it is necessary to correlate clinical features with CT findings for an accurate diagnosis

    Full text: Learning objectives: to make a list of diseases and syndromes which manifest as bilateral symmetric findings on computed tomography and magnetic resonance imaging; to discuss the clinical and radiological differential diagnosis for these diseases; to explain which of these conditions necessitates urgent therapy and when additional studies and laboratory can precise diagnosis. There is symmetry in human body and quite often we compare the affected side to the normal one but in neuroradiology we might have bilateral findings which affected pair structures or corresponding anatomic areas. It is very rare when clinical data prompt diagnosis. Usually clinicians suspect such an involvement but Ct and MRI can reveal symmetric changes and are one of the leading diagnostic tool. The most common location of bilateral findings is basal ganglia and thalamus. There are a number of diseases affecting these structures symmetrically: metabolic and systemic diseases, intoxication, neurodegeneration and vascular conditions, toxoplasmosis, tumors and some infections. Malformations of cortical development and especially bilateral perisylvian polymicrogyria requires not only exact report on the most affected parts but in some cases genetic tests or combination with other clinical symptoms. In the case of herpes simplex encephalitis bilateral temporal involvement is common and this finding very often prompt therapy even before laboratory results. Posterior reversible encephalopathy syndrome (PReS) and some forms of hypoxic ischemic encephalopathy can lead to symmetric changes. In these acute conditions MR plays a crucial role not only in diagnosis but also in monitoring of the therapeutic effect. Patients with neurofibromatosis type 1 or type 2 can demonstrate bilateral optic glioma combined with spinal neurofibroma and bilateral acoustic schwanoma respectively. Mirror-image aneurysm affecting both internal carotid or middle cerebral arteries is an example of symmetry in

    Craniopharyngioma is a benign, slow-growing tumor that constitues 3-9% of all intracranial tumors, and arises from epithelial remnants of the Rathke's pouch. We analyzed MR (2.0T) findings of ten cases with surgically proved craniopharyngioma retrospectively. CT was available in five cases, and Gd-DTPA was used in six cases. Characteristic findings of craniopharyngioma in MRI included multilocularity and variable signal intensities within each loculus that were more prominent in T1WI. Detection rate of calcification in MR was 60%. Six cases with Gd-DTPA enhancement revealed irregular or rim-like enhancement. MRI provides useful information regarding the location, extent and biochemical characteristics of the oraniopharyngioma as well as its relationship to the neighboring structures which will be valuable in planning surgical resection

We focus on a task of science communicators in a knowledge-intensive environment, the task of finding similar experts......, given an example expert. Our approach combines expertise-seeking and retrieval research. First, we conduct a user study to identify contextual factors that may play a role in the studied task and environment. Then, we design expert retrieval models to capture these factors. We combine these with content......-based retrieval models and evaluate them in a retrieval experiment. Our main finding is that while content-based features are the most important, human participants also take contextual factors into account, such as media experience and organizational structure.

    A variety of neoplasms can develop in each tetal organ. Most fetal neoplasms can be detected by careful prenatal ultrasonographic examination. Some neoplosms show specific ultrasonographic findings suggesting the differential diagnosis, but others do not. Knowledge of the presence of a neoplasm in the fetus may alter the prenatal management of a pregnancy and the mode of delivery, and facilitates immediate postnatal treatment. During the last five years, we experienced 32 cases of fetal neoplasms in a variety of organs. We describe their typical and ultrasonographic findings with correlating postnatal CT, MRI, and pathologic findings

    To assess the high-resolution CT (HRCT) findings of small airway abnormalities after mycoplasma pneumonia and correlate them with the findings of chest radiography performed during the acute and follow-up phases of the condition. We retrospectively evaluated HRCT and chest radiographic findings of 18 patients with clinical diagnosis of small airway disease after mycoplasma pneumonia (M:F=8:10, mean age: 8.3 years, mean time interval after the initial infection; 26 menths). We evaluated the lung parenchymal and bronchial abnormalities on HRCT (n=18). In addition, presence of air-trapping was assessed on expiratory scans (n=13). The findings of HRCT were correlated with those of chest radiography performed during the acute phase of initial infection (n=15) and at the time of CT examination (n=18), respectively. HRCT revealed lung parenchymal abnormalities in 13 patients (72%). A mosaic pattern of lung attenuation was noted in ten patients (10/18, 56%) and air-trapping on expiratory scans was observed in nine (9/13), 69%). In nine of 14 (64%) with negative findings at follow-up chest radiography, one or both of the above parenchymal abnormalities was observed at HRCT. In four patients (27%), parenchymal abnormalities were seen at HRCT in areas considered normal at acute-phase chest radiography. Bronchiectasis or ateclectasis was observed in eight (44%) and four (22%) patients, respectively, at HRCT. The CT features of Swyer-James syndrome such as a unilateral hyperlucent lung with reduced lung volume and attenuated vessels were noted in two patients(11%). HRCT can clearly demonstrate lung parenchymal and bronchial abnormalities of small airway disease after mycoplasma pneumonia in children.

    For the treatment for pulmonary hypertension (PH), the differential diagnosis of its causal diseases is essential. To determine whether X-ray CT is useful for differentiating PH, we reviewed CT findings of 53 patients (18 men and 35 women, mean age of 44.9) given a diagnosis of PH, consisting of 25 with primary pulmonary hypertension (PPH), 18 with chronic pulmonary embolism (cPE), 6 with Eisenmenger syndrome, 5 cases of collagen diseases, 2 of acute PE, and 1 of cor pulmonale. The intrapulmonary distribution of CT findings (ground glass opacity [GGO], mosaic attenuation, striation and/or infiltration, and interlobular septal thickening) were reviewed and scored on a 4-point scale (grade 0: no findings, 1: involving one third of the lung, 2: involving one-two thirds, and 3: diffuse distribution) by two radiologists who reached a consensus. PPH showed preferentially diffuse distribution of GGO as compared with cPE (p<0.05). However, there was no apparent relationship between the pulmonary vascular resistance and the distribution of GGO in PPH cases. The mosaic attenuation pattern was more frequent in cPE (43%) than PPH (12%; p<0.05). Striation and/or infiltration was observed in 36% of cPE, but only 4% of PPH. Interlobular septal thickening was seen in 16% of PPH, and 0% in cPE. Evaluation of CT findings is useful to differentiate PH. (author)

    Full Text Available Several demyelinating disorders can affect children. The differential diagnosis between these diseases is usually an arduous task. Diagnostic criteria have been proposed for some of these disorders, however most of them have not yet been clinically and prospectively validated. Here we present a case of a ten year-old boy with recurrent bilateral optic neuritis and spinal cord involvement. Clinical and cerebrospinal fluid data have fulfilled diagnostic criteria for Devic's neuromyelitis optica (NMO. The differential diagnosis with multiple sclerosis (MS has become troublesome since not only optic nerves and spinal cord were involved. In one of the relapses a left hemiparesis with facial involvement was registered. Magnetic resonance imaging was also compatible with MS. This case illustrates that CNS demyelinating disorders can fulfill diagnostic criteria for more than one demyelinating disease, making the clinical judgment an important tool in the management of these patients.Diversas doenças desmielinizantes podem ocorrer em crianças, sendo muitas vezes o diagnóstico diferencial entre elas difícil. Critérios diagnósticos têm sido propostos para algumas destas entidades, entretanto nenhum deles pode ser considerado definitivo. O objetivo deste trabalho é apresentar o caso de um paciente de 10 anos de idade, com quadro recorrente de neurite óptica bilateral e mielopatia. Os dados clínicos e liquóricos preencheram critérios para o diagnóstico de neuromielite óptica de Devic. O diagnóstico diferencial foi especialmente difícil em relação à esclerose múltipla, pois não apenas os nervos ópticos e medula foram acometidos, visto que em um dos surtos registrou-se hemiparesia, com acometimento facial. A ressonância magnética foi também compatível com esclerose múltipla. Este caso ilustra que pacientes com doenças desmielinizantes do SNC podem preencher critérios diagnósticos para mais de uma delas, o que torna o julgamento cl

    In a retrospective review of biphasic upper gastrointestinal (GI) tract examinations in 300 consecutive patients with abdominal pain, blood loss, nausea and vomiting, weight loss or dysphagia, the author evaluated the frequency of radiographic findings suggestive of gastritis. Forty-eight patients had undergone endoscopy within 1 week of upper GI tract examination. ''Best findings'' were defined by receiver operating characteristic wave analysis of individual findings, including aphthous lesions, serrated or nodular folds, marginal spiculation, and luminal constriction. Most false negative studies were in the fundus or proximal body; most false positive studies were in the antrum. They present a pictorial dictionary of findings and data for use of ''best findings'' to improve sensitivity and specificity in the diagnosis of gastritis

    To describe chest radiographic and CT findings of silicosis, and to compare their findings. Ten coal miners and six stonemasons were included in this study. All were male and their mean age was 53.1. The mean duration of dust exposure was 15.2 years(range, 5-30 years) in coal miners and 25.3 years(range, 15-35 years) in stonemasons. Chest radiographs(n=16), conventional CT scans(n=4), and high resolution CT(HRCT) scans(n=13) were evaluated. Parenchymal abnormalities were interpreted on the basis of ILO standard films(1980) in chest radiographs and on the basis of CAP(College of American Pathologists, 1979) in CT(HRCT) films. Chest radiographs revealed large opacities(n=8), small opacities(n=6), and normal findings(n=2). Type r(n=4) and category 1/1(n=2) were most common for small opacities, while for large opacities, category B(n=4) and category c(n=4) were most common. These small and large opacities were located predominantly in the area of the upper and middle lung. Associated findings were emphysema(n=7), eggshell nodal calcifications(n=3), pneumothorax(n=3), C-P angle blunting(n=4), and pleural thickening(n=1). CT scans revealed micronodules(n=16), nodules(n=3), and progressive massive fibrosis(PMF, n=8). All these lesions were located in the upper and middle lungs, especially in the central portion of the posterior lung. PMF showed diffuse and homogenous(n=3) and puntate(n=2) calcifications, cavitations(n=5), air bronchograms(n=3), and necrosis(n=1). Peripheral paracicatrical emphysema was associated with PMF(n=8). Other findings were pneumothorax(n=4), emphysema(n=10), hilar and mediastinal nodal enlargement(n=11) bronchial wall thick- enings(n=6), bronchiectasis(n=1), pleural thickening(n=7), parenchymal fibrosis(n=1), and pulmonary tuberculosis(n=2). Small and large opacities in chest radiographs and micronodules, nodules, and PMFs in CT (HRCT) films were located predominately in the upper and middle lungs, especially in the central portion of the

    A group of 23 pediatric patients seropositive for HIV antibody were studied by computed tomography and evaluated neurodevelopmentally. Significant neurodevelopmental delays were found in over 95% of the patients studied. CT findings in six patients were normal and thirteen of 23 (57%) had prominence of the CSF spaces. Less frequent findings included calcifications in the basal ganglia and white matter. Cerebral mass lesions included one case of lymphoma and one case of hemorrhage. The CT findings in the pediatric age group differs from the adult population in that that contrast enhancing inflammatory mass lesions are uncommon.

    Systemic lupus erythematosus(SLE) is a systemic disease of unknown etiology. Its main pathology is vasculitis and serositis, due to deposition of the immune complex or antibodies. Most findings are nonspecific ; abdominal manifestations include enteritis, hepatomegaly, pancreatic enlargement, serositis, lymphadenopathy, splenomegaly, nephritis, interstitial cystitis, and thrombophlebitis. We described radiologic findings of various organ involvement of SLE; digestive system, serosa, reticuloendothelial system, urinary system, and venous system. Diagnosis of SLE was done according to the criteria of American Rheumatism Association. Understanding of the variable imaging findings in SLE may be helpful for the early detection of abdominal involvement and complications.

    CT is useful in the evaluation of patients with newly diagnosed or highly suspected lung cancer. The principal role of CT is to screen those patients with metastatic disease beyond the hili from an attempt at curative thoracotomy. While CT is regarded as very sensitive, it is not considered highly specific, and thus a surgical procedure is usually recommended for definitive diagnosis of most ''positive'' CT findings. However, the authors demonstrate a few characteristic CT findings that are highly predictive of unresectable metastatic disease. These CT findings include massive mediastinal lymphadenopathy, diffuse mediastinal infiltration, pericardial involvement, vascular encasement, and advanced chest wall invasion

    2003-12-01

    To evaluate the imaging findings of abdominal wall endometriosis. In seven of 17 patients with surgically proven endometriosis of the abdominal wall, we retrospectively reviewed the findings of radiologic studies such as abdominal US (n=3), CT (n=4), and MRI (n=1). One patient under went more than one type of imaging, apparently. The surgical history of the seven, and their symptoms and preoperative diagnosis were reviewed, and the size, location, margin and nature of the mass, and the contrast enhancement patterns observed at radiologic studies, were assessed. The chief symptoms were palpable abdominal wall mass (n=5) and lower abdominal pain (n=2) around a surgical scar. Previous surgery included cesarean section (n=5), cesarean section with oophorectomy (n=1) and appendectomy (n=1). Masses were located in the subcutaneous fat layer (n=5) or rectus abdominis muscle (n=2), and their maximum diameter was 2.6 cm. Imaging findings, which correlated closely with the pathologic findings, included a well (n=5) or poorly marginated (n=2) solid mass, with a focal cystic area apparent in two cases. Although imaging findings of abdominal wall endometriosis may not be specific for diagnosis, the presence of a solid abdominal mass in female patients of reproductive age with a history of surgery is a diagnostic pointer.

    Skiing and hiking outside the boundaries remains an attractive wilderness activity despite the danger of avalanches. Avalanches occur on a relatively frequent basis and may be devastating. Musculoskeletal radiologists should be acquainted with these injuries. Fourteen avalanche victims (11 men and 3 women; age range 17-59 years, mean age 37.4 years) were air transported to a high-grade trauma centre over a period of 2 years. Radiographs, CT and MR images were prospectively evaluated by two observers in consensus. Musculoskeletal findings (61%) were more frequent than extraskeletal findings (39%). Fractures were most commonly seen (36.6%), involving the spine (14.6%) more frequently than the extremities (9.8%). Blunt abdominal and thoracic trauma were the most frequent extraskeletal findings. A wide spectrum of injuries can be found in avalanche victims, ranging from extremity fractures to massive polytrauma. Asphyxia remains the main cause of death along with hypoxic brain injury and hypothermia. (orig.)

We retrospectively analyzed simple chest and abdominal radiographs, and brain sonograms in 36 newborn infants (preterm : term=23 :13). With neonatal sepsis diagnosed by blood culture and clinical manifestations. Pulmonary parenchymal infiltrate excluding respiratory distress syndrome and pulmonary edema or atelectasis was found in 22 infants (61%). Paralytic ileus, hepatosplenomegaly, and necrotizing enterocolitis were present in 18(50%), 9(25%), and 1(3%) infants, respectively, while skeletal changes suggesting osteomyelitis were found in three. Brain sonography was performed in 29 infants and in four, abnormalities were seen ; these comprised three germinal matrix hemorrhages and one intraparenchymal hemorrhage. In six patients(17%) radiologic examinations revealed no abnormality. In patients with neonatal sepsis, pulmonary infiltrates and paralytic ileus were common abnormalities. Although these were nonspecific, radiologic findings may be used to supplement clinical and laboratory findings in diagnosing neonatal sepsis and planning its treatment

    Clinical findings and CT findings in 73 cases of cerebral palsy were studied. The causes of cerebral palsy were presumed to be as follows: abnormal cerebral development (36%), asphyxial delivery (34%), and immature delivery (19%), etc. CT findings were abnormal in 58% of the 73 cases, 83% of the spastic tetraplegia patients and all of the spastic hemiplegia patients showed abnormal CT findings. All the patients with spastic monoplegia presented normal CT findings. In 75% of the spastic hemiplegia cases, the CT abnormalities were due to cerebral parenchymal abnormality such as porencephaly and regional low absorption. In cases of spastic tetraplegia, cerebral parenchymal abnormality was found only in 10%. Cortical atrophy was found only in 15 of the 73 cases, whereas central atrophy was found in 36 cases.

    To evaluate MRI findings of Guillain-Barre syndrome. In six patients with Guillain-Barre syndrome diagnosed by clinical, cerebrospinal fluid and electrophysiologic findings, a retrospective review of MR findings was conducted. Follow-up MRI scans were carried out in two patients showing minimal clinical improvement. Marked or moderate enhancement of thickened nerve roots was seen in all cases on gadopentetate dimeglumine enhanced axial T1-weighted images. Two patterns were seen; one was even enhancement of both anterior and posterior nerve roots (n=1) and the other was enhancement of anterior nerve roots only (n=5). Enhancement and thickness of nerve roots was seen to have slightly decreased on MRI follow-up at 32 and 50 days; clinical and electrophysiologic examination showed minimal improvement. Although MRI findings of nerve root enhancement are nonspecific and can be seen in neoplastic and other inflammatory diseases, the enhancement of thickened anterior nerve roots within the cal sac suggests Guillain-Barre syndrome.

    This study is to describe authors' experience on mammographic findings of breast cancer and to know if there is difference between 35 years of age or younger and older groups. Mammograms of 72 patients with breast cancer detected from January, 1991 to December, 1993 were retrospectively analysed. Mammographic findings were classified into mass only, mass with microcalcifications, microcalcifications only and others. Marginal characteristics of mass were classified into spiculated, poorly marginated and well marginated. Shape of microcalcifications were classified into casting, granular and mixed types. These findings were compared between 35 years of age or younger and older groups. Mammogram showed mass only in 33 patients (46%), mass with microcalcifications in 26 patients (36%), microcalcifications only in seven (10%) and other findings in six (8%). Other findings were architectural distortion, asymmetric high density and incidental breast carcinoma from paraffinoma in one patient respectively, and dense breast in three patients. The margins of the breast mass were spiculated in ten (17%). poorly marginated in 30 (51%), well-marginated in 19 (32%). Shape of microcalcifications were casting type in 13 (40%). granular in 14 (42%) and mixed in six (18%) cases. 3 patients had dense breast with which mammography did not demonstrate the lesion. 3 patients without mammographically demonstrable lesions due to dense breasts were under 35 years in age, and there was statistically significant difference between the two groups (ρ -value < 0.05). Microcalcifications only was more common findings in 35 years of age or younger. The most important mammographic findings of breast cancer were mass and microcalcifications. Architectural distortion and asymmetric high density were additional findings. In 35 years of age or younger, microcalcifications only was an important finding because mass lesions are frequently masked by dense breast. Thus other imaging modalities, such as

    To demonstrate MR findings of cerebral palsy (CP), correlation with clinical findings, and differences between the full-term and pre-term group. Brain MRI of 94 patients with cerebral palsy (CP) were reviewed. The frequency of each MR finding, statistical correlation with clinical findings including type, severity and extent of CP, and differences between the full-term and pre-term group were analyzed. Abnormal MR findings were found in 83 patients(88%), and were as follows : diffuse brain atrophy(30%); periventricular leukomalacia(PVL)(28%); infarction(11%), basal ganglia abnormality(11%); delayed myelination(10%); nonspecific tissue loss or encephalomalacia(9%); and cortical dysplasia(7%). Hemiplegia was the most common condition among patients with infarction, and was found in 80% of this group; diplegia was found in 50% of cases with diffuse brain atrophy, while paraplegia was found in 36% of those with normal MR findings (p < .05). Mild symptoms were dominant in patients with normal MR findings(82%) and in those with infarctions(90%)(p < .05). PVL was the dominant finding in the pre-term group (65%) whereas findings in the full-term group varied; in this group, 38% of MR findings suggested prenatal insults. Possible causative factors were found in 66% of the full-term and 80% of the pre-term group. Perinatal factors were dominant in the pre-term group(81%), whereas prenatal and postnatal factors showed relatively higher frequencies in the full-term group(30% and 24%, respectively). Diffuse brain atrophy and PVL were the most common MR findings. The extent of CP the pre-term correlated well with MR findings. PVL and perinatal factors were dominant in the pre-term group, whereas variable MR findings and relatively higher frequencies of pre- and postnatal factors were found in the full-term group.

    Although colonic diverticulitis has no indication for operation, but in some mistaken cases were operated with a diagnosis of acute appendicitis. We evaluated the CT findings of colonic diverticulitis about 19 cases and of asymptomatic colonic diverticula about 15 cases retrospectively. Diagnosis was confirmed of barium enema and operation. CT are complementary methods of examination that can delineated the range of thickening of the colon and the extension of inflammatory changes around the colon. We also believe that CT findings of colonic diverticulitis are useful for differentiating from a diagnosis of appendicitis. (author)

    In order to determine sonographic characteristic of renal tuberculosis, we retrospectively collected 27 cases during a 5 year period. Infected kidneys showed large size (52%) and lobulating contour (76%). In 19 cases of increased parenchymal echogenicity, most of them (16 cases) showed decreased parenchymal thickness. We divided hydronephrotic patterns into 4 categories; predominant calyceal dilatation with mild or no pelvic dilatation (67%), focal calyectasis without pelvic dilation (15%), parenchymal cavitation without hydronephrosis (11%) and proportional hydronephrosis with calyceal deformity (7%). Our findings suggest that disproportional hydronephrosis would be the characteristic finding of renal tuberculosis

    Triangle fibrocartilage complex (TFCC) is very small and can be visualized in MRI. We compared image findings acquired by high-resolution MRI using a 47-mm-diameter microscopy coil with arthroscopic findings and reviewed the availability and possibility of application of both these techniques. The subjects were 16 patients who underwent arthroscopy of the radiocarpal joint and MRI for the diagnosis of pain in the ulnar wrist joint. Based on image evaluation, the impaired site was categorized as follows radius attachment, disc proper, triangular ligament (upper lamina), triangular ligament (lower lamina), lunate bone cartilage face, and triquete bone cartilage face; the findings of both techniques for impaired site around part 6 were compared. Joint morphology was assessed by the gradient-recalled echo (GRE) method with T2-weighted images, and the cartilage side was analyzed the fast SE (FSE) method with proton density-weighted image. Three orthopedic surgeons and 1 radiologist interpreted the results. The impaired site was verified in all 16 patients by high-resolution MRI using a microscopy coil. The MRI findings were as follows radius attachment in 2 patients, disc proper in 4, upper lamina in 7, lower lamina in 5, lunate bone cartilage face in 3, and triquete bone cartilage face in 0. The frequency of injury according to arthroscopic findings was as follows: radius attachment in 2 patients, disc proper in 4, lunate bone cartilage face in 6, and triquete bone cartilage face in 0. The sensibility/specificity of arthroscopic findings in comparison with MRI findings was as follows: radius attachment 100%/100%, disc proper 75%/91.7%, lunate bone cartilage face 50%/100%, and triquete bone cartilage face 0%/100%. Eight of 16 patients had depression of TFCC tone, and the sensibility/specificity of arthroscopic findings in comparison with MRI findings for the depression of site and TFCC tone was as follows: upper lamina 75%/87.5% and lower lamina 50%/87.5%.

    Full Text Available Objective: It was aimed to identify skin findings those were seen in patients who undergone renal transplantation. Methods: Patients who have been followed in Erciyes University Nephrology Hospital renal transplantation outpatient clinic were included in the study. They were evaluated for dermatologic findings during routine controls. Age, gender, transplantation date, identity of organ donor, history of medications, dermatological history and dermatological findings during examination were recorded. Biopsy was performed when needed. Results: In total 94 patients, 25 female (26.6% and 69 male (73.4%, were recruited to the study. Mean age was 36±10 years. The most frequent skin finding was drug-related acne (n=20. Most common infectious disease was verruca (n=17. There were viral disease other than verruca such as herpes zoster (n=3, superficial mycosis such as onychomycosis (n=5, tinea versicolor, tinea pedis and bacterial skin disease (n=2, and paronychia (n=1 and pre-malign lesions such as actinic cheilitis and bowenoid papulosis. Besides these, stria (n=3, kserosis (n=2, cornu cutaneum, café-au-lait spots, sebaceous hyperplasia and seborrheic dermatitis, skin tag, hypertrichosis, unguis incarinatus and calcinosis were other skin findings those were seen. No malign skin lesion was observed in any of patients. Conclusion: Miscellaneous skin lesions should develop in patients those undergone renal transplantation due to long-term utilization of various immunosuppressive drugs.

Important data which are criteria of normal findings are indicated directly in the pictures and are also explained in full text and in summary form. Secondly, it teaches the systematics of interpreting a picture - how to look at it, what structures to regard in what order, and for what to look in particular. Checklists are presented in each case. Thirdly, findings are formulated in accordance with the image analysis procedure. All criteria of normal findings are defined in these formulations, which make them an important didactic element.

    Clinical nurses often struggle with a lack of time and proficiency when it comes to finding and reviewing research. Knowing where to start, and discerning which search terms will retrieve the best results, can be arduous. As expert searchers, medical librarians have the skills and knowledge to make significant contributions to the clinical team, helping nurses navigate information resources and research from start to finish. When there is not direct access to a librarian, the toolbox of resources outlined in the article can save nurses' time and effort when they require quality, evidence-based information.

    2013-02-07

    The cardiac structures are well seen on nongated thoracic computed tomography studies in the investigation and follow-up of cardiopulmonary disease. A wide variety of findings can be incidentally picked up on careful evaluation of the pericardium, cardiac chambers, valves, and great vessels. Some of these findings may represent benign variants, whereas others may have more profound clinical importance. Furthermore, the expansion of interventional and surgical practice has led to the development and placement of new cardiac stents, implantable pacemaker devices, and prosthetic valves with which the practicing radiologist should be familiar. We present a collection of common incidental cardiac findings that can be readily identified on thoracic computed tomography studies and briefly discuss their clinical relevance.

  5. Benefit finding and resilience in child caregivers.

    2014-09-01

    A substantial number of children are involved in informal caregiving and make a significant contribution to health care delivery. While this places high levels of demand on their coping resources, there is some evidence that these children find benefit in their caring role. A survey design using questionnaire data collection was used with a sample of 442 children (174 boys and 268 girls) between the ages of 12 and 16. The role of benefit finding and resilience was explored within a stress and coping model of the impact of caregiving. Hierarchical multiple regression analysis (HMRA) identified resilience and benefit finding as accounting for significant amounts of variance in positive health and mediating the impact of caregiving. In regard to negative health, only benefit finding played a significant role. Young caregivers do experience benefit finding and exhibit resilience although the relationship with caregiving burden was inverse. Benefit finding seems to be related to social recognition of the caregiving role and to family support. What is already known on this subject? There is some emerging evidence that child caregivers experience some positive effects or benefits from their caring in spite of the demands of the role. However, the main focus has been on reducing negative outcomes rather than on building resilience. What this study adds? This study provides evidence that young caregivers do experience benefit finding in situations where the role demand is not overly excessive and where the role is socially recognized. © 2013 The British Psychological Society.

  6. Electroencephalographic findings in panic disorder

    2013-12-01

    Full Text Available Some studies have reported the importance of electroencephalography (EEG as a method for investigating abnormal parameters in psychiatric disorders. Different findings in time and frequency domain analysis with regard to central nervous system arousal during acute panic states have already been obtained. This study aimed to systematically review the EEG findings in panic disorder (PD, discuss them having a currently accepted neuroanatomical hypothesis for this pathology as a basis, and identify limitations in the selected studies. Literature search was conducted in the databases PubMed and ISI Web of Knowledge, using the keywords electroencephalography and panic disorder; 16 articles were selected. Despite the inconsistency of EEG findings in PD, the major conclusions about the absolute power of alpha and beta bands point to a decreased alpha power, while beta power tends to increase. Different asymmetry patterns were found between studies. Coherence studies pointed to a lower degree of inter-hemispheric functional connectivity at the frontal region and intra-hemispheric at the bilateral temporal region. Studies on possible related events showed changes in memory processing in PD patients when exposed to aversive stimuli. It was noticed that most findings reflect the current neurobiological hypothesis of PD, where inhibitory deficits of the prefrontal cortex related to the modulation of amygdala activity, and the subsequent activation of subcortical regions, may be responsible to trigger anxiety responses. We approached some important issues that need to be considered in further researches, especially the use of different methods for analyzing EEG signals. Keywords: Electroencephalography, panic disorder, neurobiology, brain mapping.

    In spite of all advances made by modern technology, there are still regions which remoteness has made electrification of poor rural localities very difficult or impossible. The only practical solution for these localities is a local, decentralized form of electrical generation, such as solar energy. Based on its availability and potential, together with the scientific and technical advances made in photovoltaic conversion, solar energy is an alternative which is viable for many rural areas in developing countries. The technology has matured sufficiently, but in its application there is still a need for systematization for experiences, especially in the areas of planning and management. The present work deals with a project carried in the community of Chimboata, Chimboata department, Bolivia. The implementation aspects are analysed and the implementation methodology described. Finally, the forms of managing and funding this type of systems are analysed. (author)

    Fascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare. We present unique ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) findings of a biliary fascioliasis case which doesn’t have biliary obstruction or cholestasis. Radiologically, curvilinear parasites compatible with juvenile and mature Fasciola hepatica within the gallbladder and common bile duct were found. The parasites appear as bright echogenic structures with no acoustic shadow on US and hypo-intense curvilinear lesions on T2 weighted MRCP images. Imaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions

    Sonograms in forty two patients with tuberculous peritonitis of the wet-ascitic type were retrospectively analyzed. The ascites was clear in 24 patients (57%). There were septations, membranes and debris in 6 (14%), floating debris in 5 (12%), mobile strands or membranes in 4 (10%), and fixed septations in three(7%). Other findings were increased hepatic echogenicity, hepatosplenomegaly, pleural effusion, omental cake, thickened mesentery with adherent bowel loops, lymphadenopathy, thickening of the ileal wall, presented in order of frequency. The ultrasonographic findings are not specific for tuberculous peritonitis, but may give profitable information and protect the patient from unnecessary laparotomy

    A prospective study of bone scintigraphic findings has been carried out in 63 patients, firmly diagnosed as having ankylosing spondylitis. In addition to abnormal uptake of the radiotracer at the sacroiliac joints, a peripheral arthropathy has been a common finding, particularly in the proximal joints, occurring in up to 50% of patients. Increased uptake of radiotracer in the spine has also been found both diffusely and focally. Focal increases have been noted at the apophyseal joints in 40% of patients and in three patients with a sterile intervertebral diskitis, an unusual complication of this disease only diagnosed in two patients after bone scintigraphy.

    Magnetic resonance (MR) findings of the brains diagnosed to have ulegyria were reviewed. The reviewed subjects comprised six epileptic children, ranged from 2 to 16 years of age. All patients had convulsion of tonic-clonic type of various severity and had histories of ischemic-hypoxic or hypoglycemic episode in the perinatal or postnatal period. T 1 -weighted images demonstrated the findings precisely reflecting the salient macroscopic features of ulegyria; localized atrophy of the brain with mushroom-shaped cortical gyri with narrow roots and relatively spared wider crowns. T 2 -weighted images showed the areas of hyperintensity in the subcortical and deep white matter subjacent to the atrophic cortex, suggestive of cicatrical gliosis as well as cystic degeneration. The atrophic gyri were seen in the anterior and/or posterior parasagittal arterial border zones bilaterally with minimal asymmetry. Although these findings were nearly pathognomonic to ulegyria, polymicrogyria could mimic it since both are characterized by abnormally diminutive cortical gyri seen in epileptic children. In polymicrogyria, however, affected gyri are uniformly diminutive and not mushroom-shaped, the cortex is rather thickened than atrophic, the underlying white matter shows no focal hyperintensity, subcortical cystic changes are not present, and affected cortex is not restricted to arterial border zones. Even in one of our cases with extensive ulegyria, it was easy to differentiate it from polymicrogyria since parasagittal regions were most severely affected. Although the previous reports on ulegyria have been exclusively based on postmortem pathological examinations or experimental models, its easy recognition on MRI would contribute to further understanding of its clinical significance and mechanisms.

    To evaluate the magnetic resonance imaging (MRI) findings of spinal intradural extramedullary schwannomas with pathologic correlation and to determine whether these schwannomas share the imaging features of schwannomas in the peripheral nerves. The MRIs of 17 cases of pathologically proven spinal intradural extramedullary schwannomas were reviewed retrospectively, and cystic changes, enhancement, and intratumoral hemorrhage of the tumors were evaluated. Imaging features known to be common findings of schwannoma in the peripheral nerves, such as encapsulation, the target sign, the fascicular sign, and visualization of entering or exiting nerve rootlets, were also evaluated. The histopathology of the tumors was correlated with the MRI findings. Cystic changes were detected in 14 cases by MRI and in 16 cases by pathology. The most common pattern of enhancement was a thick peripheral septal pattern (70.59%). Intratumoral hemorrhage was detected in four cases on MRI, but in all cases on pathology. Encapsulation was observed in all cases. The fascicular sign was seen in only four cases, and thickening of an exiting rootlet was visualized in one case. None of the cases showed the target sign. Spinal intradural extramedullary schwannomas were typical encapsulated cystic tumors and had few imaging features of schwannomas in the peripheral nerves.

    We prospectively compared whole-body multidetector computed tomography (MDCT) and 3.0T magnetic resonance (MR) images with autopsy findings. Five cadavers were subjected to whole-body, 16- channel MDCT and 3.0T MR imaging within two hours before an autopsy. A radiologist classified the MDCT and 3.0T MRI findings into major and minor findings, which were compared with autopsy findings. Most of the imaging findings, pertaining to head and neck, heart and vascular, chest, abdomen, spine, and musculoskeletal lesions, corresponded to autopsy findings. The causes of death that were determined on the bases of MDCT and 3.0T MRI findings were consistent with the autopsy findings in four of five cases. CT was useful in diagnosing fatal hemorrhage and pneumothorax, as well as determining the shapes and characteristics of the fractures and the direction of external force. MRI was effective in evaluating and tracing the route of a metallic object, soft tissue lesions, chronicity of hemorrhage, and bone bruises. A postmortem MDCT combined with MRI is a potentially powerful tool, providing noninvasive and objective measurements for forensic investigations

    It is not always easy to detect and interpret radiologic findings of pediatric pneumonia. Authors retrospectively analysed radiologic findings of 102 cases of pediatric primary pneumonia treated at Yeong-Deung-Po City Hospital between 1988 and 1990 to understand the past trend of radiologic pattern and to attain helpful information in diagnosing pediatric pneumonia hereafter. Results were as follows. Positive radiologic findings were noted in 85 cases (84%), but 17 cases (16%) showed indefinite lesion. The cases of infantile pneumonia (under 1 year of age) were 44. The most frequent finding was bilateral peribronchial infiltration with overearation (21 cases, 48%), followed by multiple patchy atelectasis associated with the findings of bilateral peribronchial infiltration and overaeration (nine cases, 23%), peribronchial infiltration without definite overaeration (six cases, 14%), alveolar consolidation superimposed on the peribronchial infiltration (three cases, 6%), alveolar consolidation (three cases, 6%) and bronchopneumonic pattern (two cases, 4%). The cases of pre-school age (1-5 years of age) were 34. Bilateral parahilar peribronchial infiltration was the most frequent finding (24 cases, 71%), followed by alveolar consolidation (six cases, 17%) and bronchopneumonic pattern (four cases, 12%). The cases of school age (over 6 years of age) were seven. Six cases (85%) showed alveolar consolidation and one case (15%) showed bronchopneumonic pattern. In short, the younger the patient was, the more frequently the interstitial infiltration occurred. Furthermore, overaeration and patchy atelectasis were unique findings of infantile pneumonia. After the school age, the pattern of pneumonia became similar to that of adults

    Background: A high-voltage electrical burn is often associated with deep muscle injuries. Hidden, undetected deep muscle injuries have a tendency for progressive tissue necrosis, and this can lead to major amputations or sepsis. MRI has excellent soft tissue contrast and it may aid in differentiating the areas of viable deep muscle from the areas of non-viable deep muscle. Purpose: To describe the MR imaging findings of a high-voltage electrical burn in the upper extremity with emphasis on the usefulness of the gadolinium-enhanced MRI and to compare the MR imaging findings with angiography. Material and Methods: We retrospectively reviewed the imaging studies of six patients with high-voltage electrical burns who underwent both MRI and angiography at the burn center of our hospital from January 2005 to December 2009. The imaging features were evaluated for the involved locations, the MR signal intensity of the affected muscles, the MR enhancement pattern, the involved arteries and the angiographic findings (classified as normal, sluggish flow, stenosis or occlusion) of the angiography of the upper extremity. We assessed the relationship between the MR imaging findings and the angiographic findings. Results: The signal intensities of affected muscles were isointense or of slightly high signal intensity as compared with the adjacent unaffected skeletal muscle on the T1-weighted MR images. Affected muscles showed heterogenous high signal intensity relative to the adjacent unaffected skeletal muscle on the T2- weighted images. The gadolinium-enhanced T1-weighted images showed diffuse inhomogeneous enhancement or peripheral rim enhancement of the affected muscles. The angiographic findings of the arterial injuries showed complete occlusion in three patients, severe stenosis in two patients and sluggish flow in one patient. Of these, the five patients with complete occlusion or severe stenosis on angiography showed non-perfused and non-viable areas of edematous muscle on

    Rhabdomyolysis is defined as skeletal muscle necrosis. Ultrasound assessment has recently become a useful tool for the diagnosis and monitoring of muscle diseases, including rhabdomyolysis. A case is presented on the ultrasound findings in a patient with rhabdomyolysis. To highlight the importance of ultrasound as an essential part in the diagnosis in rhabdomyolysis, to describe the ultrasound findings, and review the literature. A 30 year-old with post-traumatic rhabdomyolysis of both thighs. Ultrasound was performed using a Philips Sparq model with a high-frequency linear transducer (5-10MHz), in low-dimensional scanning mode (2D), in longitudinal and transverse sections at the level of both thighs. The images obtained showed disorganisation of the orientation of the muscle fibres, ground glass image, thickening of the muscular fascia, and the presence of anechoic areas. Ultrasound is a useful tool in the evaluation of rhabdomyolysis. Copyright © 2015 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A. All rights reserved.

    A spectrum of nodular haustral thickening and an 'accordion' pattern have been reported as specific features of pseudomembranous colitis (PMC) in adults. A retrospective review of nine patients with PMC was performed to assess whether this spectrum of CT findings also occurred in children. In four girls and five boys, CT scans were performed within 3 days of a positive stool toxin assay for Clostridium difficile. Documented CT abnormalities included nodular haustral thickening, the 'accordion' pattern, colonic wall thickening, ascites, and pericolonic edema. These results were then correlated as to their impact on the clinical outcome. Circumferential colon wall thickening was identified in 7/9 (78%) patients (mean thickening 14.5 mm). Nodular haustral thickening was identified in 4/9 (44%) and the 'accordion' pattern in 2/9 (22%). Other findings included pericolonic edema in 3/9 (33%) and ascites in 1/9 (11%). Wall thickening was confined to the left colon and rectum in 2/9 (22%), to the right colon in 2/9 (22%), and involved the whole colon in 3/9 (33%). Although CT findings associated with PMC in children may be suggestive for this diagnosis, CT is less specific than laboratory and clinical findings. (orig.)

    From March 1977 to July 1979, 69 cases of angiograms of hepatocellular carcinoma were observed in Seoul National University Hospital. The findings of selective celiac and/or hepatic arteriography in total 69 cases of confirmed hepatocellular carcinoma, with clinical and laboratory findings, were analyzed. The summarized results are as follows; 1. Among 69 cases od hepatoma, 62 were male and 7 were female with sex ratio of 8.9 : 1. Peak incidence is 5th to 7th decades (72.5%). Epigastric pain, indigestion, and palpable mass in right upper quadrant were common symptoms and sign. Laboratory findings showed elevated serum alkaline phosphatase more than 5 Bodansky unit in 75.4%. Alpha-feto protein was positive in 65.2% of all the patients. 2 All 69 cases were classified into 31 cases of massive type, 22 cases of diffuse type, and 16 cases of nodular type, in accordance with angiographic gross anatomy. The frequency of angiographic findings were hypervascularities and tumor vessels (100%), tumor stainings (98.5%), arteriovenous shunt (71.0%), displacement of intrahepatic arteries (66.7%), vascular lakes and channel (59.4%). Encasement of hepatic artery and portal vein regurgitation was respectively 4 cases. Tumor mass in portal vein were 6 cases and tumor mass in hepatic vein was 1 case. 3. Intraarterial infusion of 5-FU was performed in 15 hepatoma patients, and the results were that angiographic improvement was demonstrated in 3 cases, no improvement in 8 cases, and incomplete infusion in 4 cases. 4. The selective celiac and/or hepatic angiograms are excellent diagnostic tools as well as therapeutic management for intraarterial infusion of anticancerous drugs.

    CT findings in 137 patients with peritoneal cacinomatosis were reviewed to determine the CT signs of peritoneal malignancy. CT of the 20 liver cirrhosis and 17 tuberculous peritonitis were also reviewed to define the differential point between benign and malignant peritoneal change. The results were as follows. 1. The most common primary malignancy encountered in peritoneal carcinomatosis was stomach Ca.(50.4%), followed by pancreas Ca, hepatoma, colon Ca. and ovarian Ca. 2. Ascites was the most common CT feature of peritoneal malignancy, present in 99 cases (72.3%). The amount of ascites was voluminous, grade III in 70% of cases and showed high density ascites with average 23 Hounsfield units. 3. Greater omentum involvement was noted in 88 patients, peritoneum in 71 patients and mesentery in 65% patients. There was no correlation of the primary malignancy type with the incidence or pattern of the above mentioned site. 4. Bowel wall thickenings were observed in 51 patients, among which transverse colon was most frequently involved. 5. Mean attenuation value of ascites in liver cirrhosis was 10.7 HU, which was much lower than that of peritoneal carcinomatosis. 6. Even though intraperitoneal findings in Tbc. Peritonitis showed tendency of relatively small amount of ascites with more predominant mesenteric change, but, the findings of high density ascites, change of peritoneum and omentum etc. were very similar to those of peritoneal carcinomatosis. Therefore, based on only intraperitoneal change, differential diagnosis between them was difficult. 7. False negatives in CT diagnosis of peritoneal carcinomatosis occurred in 7 cases. There were tiny nodular changes in intraperitoneal cavity without ascites on operative findings

    To study standard MRI and dGEMRIC in patients with symptomatic FAI undergoing surgical intervention and compare them with intra-operative findings to see if they were corroborative. Sixteen patients with symptomatic FAI that warranted surgical intervention were prospectively studied. All patients underwent plain radiographic series for FAI assessment followed by standard MRI and dGEMRIC. Subsequently, patients were surgically treated with safe dislocation and the joint was evaluated for any macroscopic signs of damaged cartilage. Data were statistically analyzed. A total of 224 zones in 16 patients were evaluated. One hundred and sixteen zones were intra-operatively rated as normal with mean T1 values of 510.1 ms ± 141.2 ms. Eighty zones had evidence of damage with mean T1 values of 453.1 ms ± 113.6 ms. The difference in these T1 values was significant (p = 0.003). Correlation between standard MRI and intra-operative findings was moderate (r = 0.535, p < 0.001). Intra-operative findings revealed more damage than standard MRI. On standard MRI, 68.6% zones were graded normal while 31.4% had evidence of damage. On intra-operative visualization, 56.4% zones were graded normal and 43.6% had evidence of damage. Correlation between dGEMRIC and intra-operative findings turned out to be weak (r = 0.114, p < 0.126). On T1 assessment 31.4% of zones were graded as normal and 68.6% as damaged. dGEMRIC was significantly different between normal and affected cartilage based on intra-operative assessment. The correlation for morphological findings was limited, underestimating defects. By combining morphological with biochemical assessment dGEMRIC may play some role in the future to prognosticate outcomes and facilitate surgical planning and intervention. (orig.)

    Authors retrospectively analyzed ultrasonographic findings of 61 cases of breast lesions which were proven pathologically at Daerim St. Mary's Hospital from May 1987 to February 1990. The results were as follows : 1. Of all 61 cases, there were 27 fibroadenomas, 13 fibrocystic diseases, 11 carcinomas, 8 abscesses, 1 sclerosing adenosis, and 1 intraductal papilloma. 2. Findings suggesting benignancy were smooth contour, round or oval shape, homogeneously echolucent internal echo, echogenic boundary echo, and posterior enhancement. In the cases of abscess, the findings were rather irregular contour, strong posterior enhancement, and dirty, inhomogeneous internal echo. While irregular and lobulated shape, inhomogeneous and mixed internal echo and pectoral muscle invasion were suggested for malignancy. 3. The sensitivity was 98% and the specificity 58% in benign mass excluding abscesses, 63% and 98% in abscesses, and 55% and 98% in carcinomas. In conclusion, ultrasonography is one of the excellent imaging modality for detecting breast lesions larger than 5 mm in size, but unfortunately some of the malignant tumors simulated benignancy, thus we considered fine needle aspiration biopsy and adjunctive imaging modalities such as film mammography must be followed for better detection of breast cancer

    Bipartite patella is a known cause of anterior knee pain. Our purpose was to detail the magnetic resonance imaging (MRI) features of bipartite patella in a retrospective cohort of patients imaged at our institution. MRI exams from 53 patients with findings of bipartite patella were evaluated to assess for the presence of bone marrow edema within the bipartite fragment and for the presence of abnormal signal across the synchondrosis or pseudarthrosis. Any other significant knee pathology seen at MRI was also recorded. We also reviewed 400 consecutive knee MRI studies to determine the MRI prevalence of bipartite patella. Of the 53 patients with bipartite patella 40 (75%) were male; 35 (66%) had edema within the bipartite fragment. Of the 18 with no edema an alternative explanation for knee pain was found in 13 (72%). Edema within the bipartite fragment was the sole finding in 26 of 53 (49%) patients. Bipartite patella was seen in 3 (0.7%) of 400 patients. In patients with bipartite patella at knee MRI, bone marrow edema within the bipartite fragment was the sole finding on knee MRI in almost half of the patients in our series. (orig.)

    MRI is widely used as the imaging of choice for spinal disorders and may reveal either a clinically insignificant incidental abnormality or a significant lesion, unrelated to the spine, which may explain the patient's symptoms. This article attempts to establish the importance of such findings and describes a sensible approach to the reporting of MRI examinations of the spine with special attention to the incidental findings commonly encountered. The MRI characteristics of such findings are briefly described.

  10. Musculoskeletal Findings in Behcet's Disease

    2012-01-01

    Full Text Available Behcet's disease is a multisystem disease characterized by recurrent oral and genital ulcers, relapsing uveitis, mucocutaneous, articular, gastrointestinal, neurologic, and vascular manifestations. Rheumatologic manifestations may also occur in Behcet's disease, and arthritis and arthralgia are the most common musculoskeletal findings followed by enthesopathy, avascular necrosis, myalgia, and myositis. Although the main pathology of Behcet's disease has been known to be the underlying vasculitis, the etiology and exact pathogenesis of the disease are still unclear. Musculoskeletal findings of Behcet's disease, the relationship between Behcet's disease and spondyloarthropathy disease complex, and the status of bone metabolism in patients with Behcet's disease were discussed in this paper.

    A prospective study of bone scintigraphic findings has been carried out in 63 patients, firmly diagnosed as having ankylosing spondylitis. In addition to abnormal uptake of the radiotracer at the sacroiliac joints, a peripheral arthropathy has been a common finding, particularly in the proximal joints, occurring in up to 50 percent of patients. Increased uptake of radiotracer in the spine has also been found both diffusely and focally. Focal increases have been noted at the apophyseal joints in 40 percent of patients and in three patients with a sterile intervertebral diskitis, an unusual complication of this disease only diagnosed in two patients after bone scintigraphy

    Computed tomography was performed on 5 patients with chronic cerebral paragonimiasis. CT showed solitary or multiple, amorphous, round, or oval calcifications, and ventricular enlargement in all 5 cases. A large low-density area is also found in 4 of the 5 cases. These CT findings are compatible with previously reported findings of simple X-ray films of the skull, pneumoencephalography, and pathological studies. (author)

    To assess the diagnostic performance of CT signs of gastric volvulus in both confirmed cases and control subjects. We retrospectively reviewed CT findings in 10 patients with surgically confirmed acute gastric volvulus and 20 control subjects with gastric distension. Two radiologists independently evaluated CT images for risk factors of gastric volvulus, direct findings of gastric volvulus by assessing gastric dilatation, the presence of an antropyloric transition point, the respective position of the different stomach segments and of the greater and lesser curvatures, stenosis of the gastric segments through the oesophageal hiatus and for findings of gastric ischemia. The sensitivity and specificity of each finding were calculated. The most sensitive direct signs of gastric volvulus were an antropyloric transition point without any abnormality at the transition zone and the antrum at the same level or higher than the fundus. The presence of both these two findings as diagnostic criteria of gastric volvulus had 100% sensitivity and specificity for the diagnosis of gastric volvulus. There was no association between CT signs of ischemia and final bowel ischemia at pathology. CT is both highly sensitive and specific for diagnosing acute gastric volvulus. CT is highly reliable for diagnosing acute gastric volvulus with two findings. The two signs are gastropyloric transition zone and abnormal location of the antrum. This allows fast surgical management of this emergency.

    Incidental cardiovascular findings are a frequent phenomenon in computed tomography (CT) examinations. As the result of a dedicated PubMed search this article gives a systemic overview of the current literature on the most important incidental cardiovascular findings, their prevalence and clinical relevance. The majority of incidental cardiovascular findings are of only low clinical relevance; however, highly relevant incidental findings, such as aortic aneurysms, thromboses and thromboembolic events can also occasionally be found, especially in oncology patients. The scans from every CT examination should also be investigated for incidental findings as they can be of decisive importance for the further clinical management of patients, depending on their clinical relevance.

    Skeletal findings in infants with Menkes disease, the most characteristic of which are metaphyseal spurs, long-bone fractures and wormian bones, have been widely reported. However, the changes in skeletal features over time are not well known. The long-term findings differ completely from those initially observed and consist of undertubulation and metaphyseal flaring, similar to the findings seen in some types of bone dysplasia. The initial and long-term radiological features in an 8-year-old boy with Menkes disease are illustrated. (orig.)

    To present the typical and atypical magnetic resonance image (MRI) findings of intramedullary spinal ependymomas, and compare these findings with pathological subtypes. Between January 2003 to November 2014, 47 patients who had spinal ependymoma with pathologic confirmation, were retrospectively reviewed with all electronic medical records and MR images. MR imaging was done in all cases, and the images of spinal ependymomas and associated enhancement patterns were correlated with pathologic findings. The enhancement patterns were categorized into four categories: homogeneous, heterogeneous, rim-enhancement, and non-enhancement. Heterogeneous enhancement was observed in 50% of the cases. Among the 47 cases, 35 cases were well-marginated, with 21 being cervically located. All lesions were centrally located in the axial axis. Most of the cases showed T1-iso signal intensity (81%) and T2-high signal intensity (72%). The hemosiderin cap sign, syringomyelia, tumoral and non-tumoral cysts were well demonstrated. The most common pathologic type was cellular ependymoma. However, due to the small sample size, we believe it inappropriate to statistically discuss the MRI findings according to the pathologic subtype. Most spinal ependymoma showed T1-iso signal intensity and T2-high signal intensity, with enhancement patterns other than homogeneous enhancement.

    Magnetic resonance imaging findings of a 38-year-old man with epithelioid sarcoma of the penis is presented. It started as a firm, painless and slowly growing nodule at the base of his penis 6 months previously which caused pain radiating to the testis during coitus. It has been well known that sarcomas may well mimic reactive processes. Initial presentation of epithelioid sarcoma may provoke considerable diagnostic difficulty, and its differentiation from benign lesions, such as Peyronie`s disease and chronic inflammation, may be a clinical problem. In our present report the MR findings are compared with those of the epithelioid sarcomas of various locations reported in the literature and differential diagnosis of the entity is discussed. To our knowledge, this is the first report regarding the MR findings of the epithelioid sarcoma of penis. (orig.) With 3 figs., 16 refs.

    Ischemic colitis in breast cancer patients being treated with taxane-based chemotherapy, which may lead to serious morbidities and even death, has recently been defined as a clinical entity. The purpose of this retrospective study was to evaluate the computed tomography (CT) findings in taxane-related colitis and determine their clinical relevance. CT scans of 41 patients at risk for taxane colitis were reviewed retrospectively for bowel and peritoneal abnormalities. Morphological findings were analyzed and correlated with clinical, pathological, and endoscopic findings. CT scans in 10 of the 41 patients showed a definitely abnormal colon with a thickened wall or distended with fluid, signs that are suggestive of colitis, in the context of the clinical picture. Radiographic changes in patients with taxane colitis are not specific but, in the appropriate context, can suggest the correct diagnosis and guide the patient's management

  3. MR imaging findings in patients with epilepsy

    1994-01-01

    We retrospectively examined the MR imaging (MRI) findings in 144 patients with epilepsy (31 with temporal lobe epilepsy and 113 with other epilepsies). 110 cases (76.4%) showed abnormal findings such as spotty lesions in white matter, hippocampal atrophy and/or signal change, ventricular dilatation and/or deformity, developmental lesions, brain tumors and so on. Hippocampal atrophy and/or signal change was shown in 74.1% of temporal lobe epilepsy, a remarkably high percentage (p<0.01) compared with the other types of epilepsies (18.1%). This finding means that hippocampal lesions may play a large part in the cause of temporal lobe epilepsy. Investigation of the relationship between clinical term and abnormal findings revealed that the longer the clinical term, the large the number of hippocampal lesions, regardless of whether it is temporal lobe epilepsy or not. Thus hippocampal lesions may occur as a result of hypoxia accompanied with seizure. Therefore we recommend horizontal and/or vertical sections of hippocampus in MR imaging of all patients with epilepsy. Even though MR finding may reflect some secondary lesions, MRI will shed some light on the proper understanding of epilepsy. (author)

    Anterior hip dislocations are rare orthopedic emergencies resulting from high-energy trauma and have unique imaging characteristics on radiography, computed tomography (CT), and magnetic resonance imaging (MRI). Imaging findings on CT and MRI allow for the prompt recognition and classification of anterior hip dislocations, which guides patient management and reduces complications. The purpose of this article is to review imaging findings of anterior hip dislocations, specifically focusing on CT and MRI. (orig.)

    Findings of magnetic resonance imaging (MRI) of the brain were retrospectively reviewed in 100 consecutive pediatric patients with epilepsy in relation to the type of epilepsy and prognosis. There were 65 boys and 35 girls, ranging in age from 3 months to 25 years. Among 100 patients, 67 (a total of 102 lesions) showed abnormal findings on MRI. Morphological abnormalities, including ventricular enlargement, atrophy and malformation, were seen in 54 patients. Periventricular (n=14), frontal (n=3), temporal (n=8) and occipital (n=7) areas were of high signal intensity on T2-weighted images. According to the type of epilepsy, MRI abnormality was seen in 34 (61%) of 56 patients with partial seizures and 33 (76%) of 44 patients with generalized seizures. When associated with cerebral palsy and mental retardation, the incidence of MRI abnormality was high. There was no sigificant correlation between MRI findings and prognosis. (N.K.).

    We retrospectively analyzed the MR findings of 12 patients with herpes simplex encephalitis (HSE) (8 months - 64 years old). MR imaging was performed on either a 0.5T (6 patients) or 2.0T (6 patients) superconducting unit with spin echo pulse sequences. The most common and characteristic MR finding consisted of non-hemorrhagic lesions in the cortices of the temporal lobes(12), and insular(6), either bilateral(7) or unilateral(5). The frontal lobe and cingulate gyrus were involved in 4 and 2 patients respectively. Petechial hemorrhage was found in 3 patients. Non-hemorrhagic lesions were shown as high signal intensities on proton and T2WI, and iso- or low signal intensities on T1WI. In conclusion, MR imaging findings described above appear to be characteristic of HSE and were found to be extremely valuable in the diagnosis of HSE

    We present a new case of trombosis of the superficial dorsal penis vein called Penile Mondor's disease. The characteristics of the disease are reviewed and the most usual diagnostic and therapeutic methods. The case of a 41 year old man is reviewed who consulted for pain and induration on the proximal part of the penis. After phisical examination and Eco-doppler was made the diagnosis of Mondor's disease. He receibed treatment with non steroidal antiinflamatories and antibiotics. The dorsal vein thrombosis is a rare disease with pain an induration of the dorsal part of the penis. The ethiology can be traumatic, neoplasic, excesive sexual activity or abstinence. Is necesary the diferencial diagnosis with esclerosant linphangitis and the most important imaging is the Eco-doppler. The treatment is based in non steroidal antiinflamatories and antibiotics wit infection. The local aplication of heparine can be useful and the surgery with thrombectomy and resection is for persistent cases.

    2006-03-15

    Purpose: To investigate the correlations of contrast-enhanced magnetic resonance (MR) imaging findings of large (>5 cm) hepatocellular carcinomas with tumor size and histopathologic findings. Materials and methods: MR imaging was performed in 30 patients with a histopathologic diagnosis of hepatocellular carcinoma. The imaging protocol included non-contrast, hepatic arterial, portal venous and late phases. The signal intensities relative to the liver, enhancement patterns and the morphologic features of the lesions were evaluated in relation to size and degree of differentiation. Results: On histopathologic examination, 12 of 30 (40%) tumors were well-differentiated (grade 1), 6 of 30 (20%) were moderately differentiated (grades 2 and 3) and 12 of 30 (40%) were poorly differentiated (grade 4). Tumor size, tumor boundary, serum alpha-fetoprotein level and portal vein invasion were found to have statistically significant correlations with the degree of differentiation (p < 0.05). Portal vein invasion, capsule formation and tumor surface characteristics showed statistically significant correlations with tumor size (p < 0.05). Conclusion: MR imaging findings of hepatocellular carcinomas larger than 5 cm are partially dependent on tumor size and degree of differentiation.

    Molla, E.; Ripolles, T.; Martinez, M.J.; Morote, V.; Rosello-Sastre, E.

    1998-01-01

    A retrospective review is presented of seven cases of epiploic appendagitis, with surgical confirmation in one case. The main clinico-analytical data and the US and CT findings are described, as well as the histopathologic features in the sole case that underwent surgical resection. We also calculated the frequency of this entity in patients undergoing emergency abdominal US on clinical suspicion of diverticulitis. In all seven cases the clinico-analytical evidence was nonspecific (localized acute abdominal pain and slight leukocytosis), mimicking in six cases the clinical presentation of sigmoid diverticulitis and in one case that of acute appendicitis. US imaging findings were characteristic: a hyperechoic mass localized under the point of maximum pain, adjacent to the anterior peritoneal wall and fixed during deep breathing. In none of the cases did color Doppler US show flow. CT findings were also typical and showed a mass with a peripheral hyperattenuated rim surrounding an area of fatty attenuation. Overall 7.1 % of patients investigated to exclude sigmoid diverticulitis finally showed findings of primary epiploic appendagitis. Primary epiploic appendagitis thus shows characteristic US and CT findings that allow its diagnosis and follow-up. This entity is much more frequent than previously reported, especially in patients referred for US to exclude sigmoid diverticulitis. (orig.)

    Eosinophilic esophagitis is increasingly recognized as a cause of dysphagia or food impaction in pediatric patients. It has a high male predominance and is often associated with a history of allergy or asthma. To correlate fluoroscopic findings in eosinophilic esophagitis with the endoscopic and histologic findings. We retrospectively reviewed the upper gastrointestinal (UGI) findings of eosinophilic esophagitis and correlated them with the clinical, endoscopic and histologic findings in a series of 17 children (12 boys, 5 girls). UGI findings were normal in 12 children, including 4 who had a normal UGI exam after endoscopic disimpaction for an obstructing food bolus. Five children had strictures identified on UGI: one was demonstrated with endoscopy. This suggests that the impactions and strictures were due to an esophageal dysmotility rather than a fixed anatomic abnormality. Because the UGI findings are frequently normal in eosinophilic esophagitis, radiologists need to have a high index of suspicion for this disease. In children with a strong clinical history, especially impaction in the absence of an esophageal stricture, endoscopy and biopsy are indicated for further evaluation. (orig.)

    1981-01-01

    Examination of EEG and cranial CT were performed in 19 cases of partial seizures with elementary symptomatology (PSES), 6 cases of partial seizures with complex symptomatology (PSCS), and 17 cases of benign focal pilepsy of childhood with Rolandic spikes (BFECRS). The results were as follows. 1) In 16 of 19 cases of PSES (84%), various abnormal CT findings such as localized cerebral atrophy (7 cases), localized cerebral atrophy complicated with porencephaly (4 cases), porencephaly alone (2 cases), and diffuse cerebral atrophy (3 cases) were found. 2) Of 6 cases of PSCS localized cerebral atrophy was found in 3 cases, porencephaly in one case, and localized calcification in one case. Normal CT findings were obtained in one case. 3) In comparison of EEG findings with CT findings in 25 cases of partial seizures CT findings correlated with the basic waves rather than the paroxysmal ones. 4) The fact that CT findings in patients with BFECRS were mostly normal suggests the functional origin of the seizures. 5) CT was valuable in partial seizures for detecting underlying disorders and predicting the prognosis.

    The CT findings in 5 patients with cerebral paragonimiasis in the chronic state are presented. The findings were: 1) multiple, densely calcified areas with a variety of round or nodular shapes in the brain, 2) a large low density area surrounding or connecting with the calcified areas, and 3) cortical atrophy and ventricular dilatation. The relation between the CT findings and the previously reported plain skull X-ray findings or neuropathological findings are discussed. (orig.)

    The results were compared of electroencephalography (EEG) and computerized tomography (CT) examinations of 250 patients with different brain affections. In intracranial expansive processes the pre-operative CT findings were positive in 100% cases, the EEG findings in 89.7% of cases. In severe traumatic affections the EEG and CT findings were positive in all cases, in mild injuries and post-traumatic conditions the EEG findings were more frequently positive than the CT. In focal and diffuse vascular affections the EEG and CT findings were consistent, in transitory ischemic conditions the EEG findings were more frequently positive. In inflammatory cerebral affections and in paroxymal diseases the EEG findings were positive more frequently than the CT. The same applies for demyelinating and degenerative affections. Findings of other authors were confirmed to the effect that CT very reliably reveals morphological changes in cerebral tissue while EEG records the functional state of the central nervous system and its changes. The two methods are complementary. (author)

    The CT findings of the acute cerebral infarction are well known. However the CT findings of early stroke within 24 hours of the onset have not been sufficiently reported. The purpose of this study is to evaluate early acute cerebral infarction on CT within 24 hours after ictus. The early and accurate CT diagnosis could lead to the appropriate therapy and improved outcome of the patients. Authors retrospectively analyzed 16 patients with early acute cerebral infarction. Acute cerebral infarction was confirmed by follow-up CT in 11 patients, SPECT in 4 patients, and MRI in 1 patient. The CT findings of early acute cerebral infarction include effacement of cortical sulci or cistern (n = 16, 100%), hyperattenuation of MCA (n = 3), obscuration of lentiform nucleus (n = 6), loss of insular ribbon (n = 6) and subtle low density in hemisphere (n = 5). The most frequent finding was effacement of cortical sulci in our study, and it was thought to be the most important sign of early acute cerebral infarction

    The early diagnosis and effective treatment of brain abscess pose a difficult clinical problem. With the advent of computed tomography, however, it appears that mortality due to intracranial abscess has significantly diminished. 54 cases of intracranial pyogenic abscess are presented. Etiologic factors and computed tomographic findings are analyzed and following result are obtained. 1. The common etiologic factors are otitis media, post operation, and head trauma, in order of frequency. 2. The most common initial computed tomographic findings of brain abscess is ring contrast enhancement with surrounding brain edema. 3. The most characteristic computed tomographic finding of ring contrast enhancement is smooth thin walled ring contrast enhancement. 4. Most of thick irregular ring contrast enhancement are abscess associated with cyanotic heart disease or poor operation. 5. The most common findings of epidural and subdural empyema is crescentic radiolucent area with thin wall contrast enhancement without surrounding brain edema in convexity of brain

    To evaluate the characteristic CT and cerebral angiographic findings in patients with acute spontaneous subdural hematomas and correlate these imaging findings with causes of bleeding and clinical outcome. Twenty-one patients with nontraumatic acute spontaneous subdural hematoma presenting during the last five years underwent CT scanning and cerebral angiography was performed in twelve. To determine the cause of bleedings, CT and angiographic findings were retrospectively analysed. Clinical history, laboratory and operative findings, and final clinical outcome were reviewed. Acute spontaneous subdural hematoma is a rare condition, and the mortality rate is high. In patients with acute spontaneous subdural hematoma, as seen on CT, associated subarachnoid or intracerebral hemorrhage is strongly indicative of intracerebral vascular abnormalities such as aneurysm and arteriovenous malformation, and cerebral angiography is necessary. To ensure proper treatment and thus markedly reduce mortality, the causes of bleedings should be prompty determined by means of cerebral angiography. (author). 20 refs., 1 tab., 4 figs.

    To compare the ancillary CT findings between superior mesenteric artery thromboembolism (SMAT) and superior mesenteric vein thrombosis (SMVT), and to determine the independent CT findings of life-threatening mesenteric occlusion. Our study was approved by the institution review board. We included 43 patients (21 SMAT and 22 SMVT between 1999 and 2008) of their median age of 60.0 years, and retrospectively analyzed their CT scans. Medical records were reviewed for demographics, management, surgical pathology diagnosis, and outcome. We compared CT findings between SMAT and SMVT groups. Multivariate analysis was conducted to determine the independent CT findings of life-threatening mesenteric occlusion. Of 43 patients, 24 had life-threatening mesenteric occlusion. Death related to mesenteric occlusion was 32.6%. A thick bowel wall (p < 0.001), mesenteric edema (p < 0.001), and ascites (p = 0.009) were more frequently associated with SMVT, whereas diminished bowel enhancement (p = 0.003) and paralytic ileus (p = 0.039) were more frequent in SMAT. Diminished bowel enhancement (OR = 20; p = 0.007) and paralytic ileus (OR = 16; p = 0.033) were independent findings suggesting life-threatening mesenteric occlusion. The ancillary CT findings occur with different frequencies in SMAT and SMVT. However, the independent findings indicating life-threatening mesenteric occlusion are diminished bowel wall enhancement and paralytic ileus.

    Objective. To analyze the MR imaging features of fibrolipomatous hamartoma (FLH) of nerves. Design and patients. MR imaging studies from six patients (three men and three women) were retrospectively reviewed by three musculoskeletal radiologists. In four patients, a biopsy of the nerve lesion was performed. In two patients, biopsy data were unavailable and the diagnosis was based on the clinical history combined with the MR imaging findings. Results and conclusion. MR imaging demonstrated fusiform nerve enlargement that was caused by fatty proliferation and thickening of nerve bundles. Nerve bundles appeared as serpentine tubular structures, hypointense on both T1- and T2-weighted images. The degree of fatty proliferation varied among patients. In addition, significant variation in the distribution of fat along the course of the nerves was noted. In three patients, FLH followed the branching pattern of the nerves, a characteristic pathologic finding. In two patients, intramuscular fat deposition (biceps and tibialis posterior muscles) was present. MR imaging findings of FLH are typical, allowing a confident diagnosis. The variation of fatty proliferation among patients and involved nerves as well as the tendency of the abnormalities to follow the branching pattern of the nerves is well demonstrated with MR imaging. FLH may present as an isolated nerve lesion, may be associated with intramuscular fat deposition, or may occur as a feature of macrodystrophia lipomatosa (MDL). (orig.). With 5 figs., 2 tabs

    A CT scan can make accurate diagnoses of most thymic masses by assessing their size, shape, and internal architecture and is especially effective in detecting pleural implants, mediastinal involvement, and pulmonary parenchymal invasion in malignant thymoma. The authors analyzed the CT findings of 10 histologically-proven thymic masses from 1983 to 1990 in Yeungnam University Hospital. There were 10 cases of thymic masses in the anterior mediastinum consisting of 6 benign, 3 invasive thymomas, and one thymolipoma, while myasthenia gravis was associated with 2 cases of benign thymomas and with one case of invasive thymomas. The CT findings of the benign thymomas (6 cases) were well-defined, bordered, round-or oval-shaped masses with a well-preserved fat plane between the thymic mass and mediastinal great vessels, with no evidence of pleural implants and lung parenchymal invasion. The CT findings of the invasive thymomas (3 cases) were irregular, marginated lobular masses with obliteration of the fat plane between the thymic mass and surrounding great vessels, with evidence of local invasion such as extension to A-P window and mass effect to bronchus. Irregular pleural thickening due to pleural metastasis, multiple metastatic lung parenchymal nodules, and multiple mediastinal lymph node enlargement were also seen in the invasive thymomas. One case of thymolipoma showed an approximately 20cm-size, well-defined fat density mass containing internal septations

    1973-01-01

    Takayasu's arteritis is a stenosing inflammatory process of unknown etiology affecting not only the aortic arch and its branches, but also the abdominal aorta, its branches and the pulmonary arteries. During the period from August 1971 to August 1973, 9 cases with Takayasu's arteries have been observed in the Seoul National University Hospital. The diagnosis was mainly based upon the aortography, which is the only practical method of delineating the extent and nature of the vascular involvement. The purpose of this paper is describe and analyze the radiographic findings, especially aortographic aspect. The results obtained are as follows: 1. The 9 cases are all female and two thirds are under 30 years of age. Headache, dizziness, absent or weak radial pulse and hypertension are the most common symptoms and signs. The laboratory data are generally unremarkable, except elevation of E.S.R. and gamma globulin fraction on electrophoresis. 2. Conventional roentgenography of the chest may be helpful but not specific in diagnosis of Takayasu's arteritis. 3. The aortographic findings are characteristic and pathognomonic in diagnosis of Takayasu's arteritis. In our cases, the most common findings are stenosis or occlusion of subclavian artery, diffuse narrowing with irregular contour of descending aorta, renal artery involvement, narrowing and aneurysmal dilatation of abdominal aorta, and multiple sites involvement. 4. Therefore, value of total aortography was stressed

    Purpose. To describe the CT findings of pathologically confirmed primary pulmonary lymphomas. Materials and methods. The CT examinations of 11 patients with pathologically proven primary pulmonary lymphoma (9 BALT lymphomas and 2 non-BALT lymphomas) were retrospectively reviewed by three radiologists. Evaluated findings included morphology (consolidation, mass, nodule), number and distribution of lesions. Other CT findings such as air bronchogram, lymphadenopathy atelectasis and pleural effusion were also assessed. Results. Pulmonary lesions were depicted as air-space consolidation (pneumonia-like) in 5 patients (45%), tumour-like rounded opacity in 4 (36%), and nodules in 4 (36%). Multiple and bilateral long lesions were seen in 3 patients (27%). Air bronchogram was present in 7 patients (63%), lymphadenopathy in 3 (27%), atelectasis in 4 (36%) and pleural effusion in only 1 (9%). Conclusions. Our results agree with previous studies regarding lesion patterns and their relative frequency. A smaller number of nodules and of multiple lesions were found compared with some previous studies. The most frequent pattern was airspace consolidation [it

    In a prospective study of 91 patients with acute pancreatitis, computed tomographic (CT) findings were correlated with the clinical type of acute pancreatitis. In acute edematous pancreatitis (63 patients; 16 with repeat CT), CT was normal (28%) or showed inflammation limited to the pancreas (61%). Phlegmonous changes were present in 11%, including one patient with focal pancreatic hemorrhage, indicating that clinically unsuspected hemorrhagic pancreatitis can occur. In acute necrotizing (hemorrhagic, suppurative) pancreatitis (nine patients; eight with repeat CT), no patient had a normal CT scan and 89% had phlegmonous changes. One patient had hemorrhagic pancreatitis and three had abscesses. In acute exacerbation of chronic pancreatitis (10 patients; three with repeat CT), there were pancreatic calcifications (70%), a focal mass (40%), and pancreatic ductal dilation (30%). On follow-up CT, the findings of acute pancreatitis did not always disappear with resolution of the clinical symptons. This was especialy true of phlegmonous pancreatitis, where the CT findings could persist for months

    Full Text Available OBJECTIVE: Carpal tunnel syndrome (CTS is defined as median nerve entrapment within the carpal tunnel at the wrist. Pain and paresthesia are the most common presenting symptoms of the patients. In this study, our aim was to identify the association between intensity of presenting symptoms and electrophysiologic findings in patients referred to the electrophysiology laboratory with prediagnosis of CTS. METHODS: Sixty-two consecutive patients who were referred to the electrophysiology laboratory with the diagnosis of CTS were enrolled in the study. The intensity of pain was determined by visual analog scale, the findings of Tinel-Phalen tests were assessed, and clinico-demographic findings were recorded. Nerve conduction studies were performed bilaterally in median and ulnar nerves. The severity of CTS was determined with electrophysiologic evaluation, and the association between electrophysiologic findings and symptoms were analyzed statistically. RESULTS: Sixty-two (57 female, 5 male patients were examined in the study. CTS was bilateral in 53 patients and unilateral in 9 patients (total 115 hands. Mean pain score was 5.78 ± 3.50. In 28 hands with a clinical diagnosis of CTS, no electrophysiologic CTS findings were found, whereas in 32 hands mild, in 41 hands moderate and in 14 hands severe findings were obtained. CONCLUSION: According to our study, there was no statistically significant association between severity of symptoms and severity of electrophysiologic findings in CTS

    To describe mammographic and ultrasonographic findings of previous chemoport insertion sites. We included patients who had abnormal findings at chemoport insertion sites on mammography and ultrasonography from 224 patients who underwent chemoport insertion and breast imaging at our institution between January, 2005, and December, 2007. Abnormal findings were identified in 16 mammographies and 14 ultrasonographies in 10 patients. The mean age was 50.9 years and the age range was from 44 to 67 years. Abnormal findings on mammography and ultrasonography were retrospectively analyzed according to ACR/BI-RADS. All cases were followed up with imaging studies for 2 years to confirm changes after chemoport insertion. Of the abnormal findings identified on mammography, focal asymmetry (7/16) was the most common. Other abnormal findings included mass (6/16), skin retraction (2/16), residual chemoport tip (1/16), and trabecular thickening (1/16). Of the abnormal findings seen on ultrasonography, skin thickening (12/14) was the most common. Other abnormal findings included mass (5/14), diffuse increased echogenicity of subcutaneous tissue (1/14), and a localized skin nodule (1/14). Abnormal findings on mammography and ultrasonography were located in the upper outer quadrant in 5 patients, upper inner quadrant in 3 patients, and mid upper portion in 1 patient. In 1 patient, the abnormal finding was only identified in the mediolateral oblique view of her mammography. Radiologists should be aware of potential abnormal findings on mammography and ultrasonography following chemoport insertion. In particular, ultrasonography is a very useful modality for detecting skin complications after chemoport insertion

    Objective: To describe radiographic features of gout that may mimic infection. Design and patients: We report five patients with acute bacterial gout who presented with clinical as well as radiological findings mimicking acute bacterial septic arthritis or osteomyelitis. Three patients had delay in the appropriate treatment with the final diagnosis being established after needle aspiration and identification of urate crystals under polarized light microscopy. Two patients underwent digit amputation for not responding to antibiotic treatment and had histological findings confirming the diagnosis of gout. Conclusion: It is important for the radiologist to be aware of the radiological manifestations of acute gout that can resemble infection in order to avoid inappropriate diagnosis and delay in adequate treatment. The definitive diagnosis should rely on needle aspiration and a specific search for urate crystals. (orig.)

    Surgery after pre-operative embolization has become the main treatment modality in angiofibroma therapy. As surgical planning is based on precise pre-operative tumour evaluation, knowledge of the characteristic growth patterns is of great interest. Analysis of tumour extension and blood supply, as well as methods of controlling intra-operative bleeding, help in determining the appropriate surgical approach. Though benign, angiofibroma demonstrates a locally aggressive nature. This fibrovascular tumour is characterised by typical radiological findings and by predictable growth patterns. The tumour extension and blood supply can be accurately determined by CT, MR imaging and angiography. With classic radiological findings, no pre-operative biopsy is necessary in most angiofibromas. Advances in radiological imaging have contributed to improved surgical planning and tumour resection. The surgeon is able to select the least traumatic approach with secure haemostatic control, which is also critical for avoiding the disturbance of facial skeletal growth in this group of young patients. Embolization, pre-operative autologous donation and the cell saver system for immediate retransfusion of the collected blood after filtration, are important tools for dealing with blood loss in angiofibroma surgery as they minimize homologous blood transfusion.

    To assess the postoperative CT findings of aortic aneurysms or dissections treared by resection-and graft replacement or continuous-suture graft-inclusion technique. We reviewed postoperative follow-up CT findings of 14 patients, 19 cases. There were 8 patients (10 cases) of aortic aneurysm and 6 patients (9 cases) of aortic dissection which involved the thoracic aorta in 9 patients (13 cases) and abdominal aorta in 5 patients (6 cases). The interval of follow-up after operation was from 9 days to 2 year 9 months. On CT scans, we analyzed the appearance of graft materials, differences of CT findings between two surgical techniques, and normal or abnormal postoperative CT findings. Most of grafts appeared as hyperdense ring on precontrast scan, and all of them were not separated from aortic lumen on postcontrast scan. On CT findings of patients who were operated by continuous-suture graft-inclusion technique, perigraft thrombus was concentrically located with sharp demarcation by native aortic wall and its density was homogeneous, but in cases of those operated by resection-and graft replacement, perigraft hematoma was eccentrically located with indistinct margin and its density was heterogeneous and native aortic wall could not be delineated. In patients without complication, perigraft thrombus or hematoma (15 cases), perigraft calcification (11 cases), residual intimal flap (6 cases), graft deformity (4 cases), perigraft air (2 cases) and reconstructed vessels (1 cases) were noted. And in one patient with complication, perigraft flow was noted with more increased perigraft hematoma. Precise knowledge of the differences of CT findings between two surgical techniques and normal postoperative CT findings is crucial to evaluated the postoperative CT findings in aortic aneurysm and dissection

    To differentiate mature and immature ovarian teratomas, using CT findings. The CT findings of ten mature ovarian teratomas (in one patient, bilateral) and ten which were immature were compared, using statistical analysis. Images were evaluated for size, margins, architecture, contents (mural nodules, fat, calcification), septa, local invasion and distant metastasis. These findings were compared with pathologic findings. Of the ten mature tumors, nine were well defined and predominantly cystic in internal architecture, and one was mixed. Mural nodules were found in six tumor, fat in all, distinct calcification in seven, and regular septa in three lesions. Of the ten immature humors, eight had irregular margins. Seven were predominantly solid in internal architecture and irregularly enhanced, two were mixed, and one was mainly cystic. Fat was detected in five lesions, indistinct scattered calcification in six, irregular septa in three, and local invasion of distant metastasis in four patients. Compared with mature ovarian teratomas, those that are immature tend to show CT findings of marginal irregularity, solid mass with irregular enhacement, scattered indistinct calcifications, septal irregularity, local invasion or distant metastasis. Our experience suggests that these findings may be helpful in differentiation of mature and immature ovarian teratomas

    To evaluate CT findings of primary adenocarcinoma of the lung and to assess distant metastasis at the time of diagnosis. CT findings of 150 patients with adenocarcinoma, confirmed by histopathologic methods, were classified as central or peripheral lesion and pattern analysis of typical findings noted in this cancer was carried out. Intra and extrathoracic metastases of adenocarcinoma were also investigated. Of 150 cases of adenocarcinoma of the lung, 121 were found to be of the peripheral type and 29 were of the central type. These peripheral lesions comprised 105 nodules, 11 consolidations, four cavities and one linear lesion, while the central lesions consisted of 19 cases of atelectasis and tens of branchial wall thickening. lung to lung(nine cases), lymphangitic(five cases), and pleural metastasis(16 cases) were presented as intrathoracic metastasis, while bone(17), brain,(six), liver(two) and adrenal metastasis(one case)were presented as extrathoracic metastasis. The most common radiologic finding of adenocarcinoma is a peripheral single mass or nodule but consolidation, cavity or tubular lesions, as well as atelectasis or bronchial wall thickening alone can be presented as unusual findings of adenocarcinoma. As a consequence, it is in many cases difficult to differentially diagnose. Distant metastasis was also noted in many cases of early T-stage lesion, so to successfully manage the patient, careful evaluation of the metastasis is essential.

    The great majority of lymphangiomas occur in the neck (75%) and axilla (20%), but extremity lymphangioma is rare. We correlate variable sonographic features of extremity lymphangioma with pathologic findings. We reviewed the sonographic findings of extremity lymphangioma in 14 patients (M:F=8:6). The all cases were histologically confirmed by operation. The variable sonographic features of extremity lymphangioma were compared to pathologic findings. The multilocular cystic mass with ill defined boundaries was distinctive sonographic appearance of extremity lymphangioma. But there were variable sonographic findings such as heterogeneous echogenic mass or homogeneous echogenic portion. The histologic section of echogenic lesion reveals clusters of abnormal

    Early diagnosis of breast vasculitis (BV) is difficult because this condition is rare and occasionally mimics breast cancer clinically or radiologically. It may present as systemic disease or as an isolated lesion in the breast, without systemic evidence. When vasculitis appears in the breast, it also might manifest as a tumor-like lesion, and in previous cases, tissue acquisition was needed for confirmation of the diagnosis because of BV's resemblance to inflammatory breast cancer. We report a case of isolated BV that was suspected of being inflammatory breast cancer clinically, but manifested as bilateral breast edema on mammography. In this case, sonographic findings included not only nonspecific edema findings that might be seen in other cases, but also suggestive findings of hypoechoic circumferential arterial wall thickening with perivascular fat infiltrations that are similar to the halo sign in large arteries but have not been reported in the breast. These are helpful for presumptive diagnosis of BV using ultrasound.

    MRIs are obtained in research in healthy and clinical populations, and incidental findings have been reported. Most studies have examined adults with variability in parameters of image acquisition and clinical measures available. We conducted a prospective study of youths and documented the frequency and concomitants of incidental findings. Youths (n = 1400) with an age range from 8-23 years were imaged on the same 3T scanner, with a standard acquisition protocol providing 1.0 mm(3) isotropic resolution of anatomic scans. All scans were reviewed by an experienced board-certified neuroradiologist and were categorized into 3 groups: 1) normal: no incidental findings; 2) coincidental: incidental finding(s) were noted, further reviewed with an experienced pediatric neuroradiologist, but were of no clinical significance; 3) incidental findings that on further review were considered to have potential clinical significance and participants were referred for appropriate clinical follow-up. Overall, 148 incidental findings (10.6% of sample) were noted, and of these, 12 required clinical follow-up. Incidental findings were not related to age. However, whites had a higher incidence of pineal cysts, and males had a higher incidence of cavum septum pellucidum, which was associated with psychosis-related symptoms. Incidental findings, moderated by race and sex, occur in approximately one-tenth of participants volunteering for pediatric research, with few requiring follow-up. The incidence supports a 2-tiered approach of neuroradiologic reading and clinical input to determine the potential significance of incidental findings detected on research MR imaging scans.

    Purpose: To evaluate lung high-resolution computed tomography (HRCT) findings in patients with Puumala hantavirus-induced nephropathia epidemica (NE), and to determine if these findings correspond to chest radiograph findings. Materials and methods: HRCT findings and clinical course were studied in 13 hospital-treated NE patients. Chest radiograph findings were studied in 12 of them. Results: Twelve patients (92%) showed lung parenchymal abnormalities in HRCT, while only 8 had changes in their chest radiography. Atelectasis, pleural effusion, intralobular and interlobular septal thickening were the most common HRCT findings. Ground-glass opacification (GGO) was seen in 4 and hilar and mediastinal lymphadenopathy in 3 patients. Atelectasis and pleural effusion were also mostly seen in chest radiographs, other findings only in HRCT. Conclusion: Almost every NE patient showed lung parenchymal abnormalities in HRCT. The most common findings of lung involvement in NE can be defined as accumulation of pleural fluid and atelectasis and intralobular and interlobular septal thickening, most profusely in the lower parts of the lung. As a novel finding, lymphadenopathy was seen in a minority, probably related to capillary leakage and overall fluid overload. Pleural effusion is not the prominent feature in other viral pneumonias, whereas intralobular and interlobular septal thickening are characteristic of other viral pulmonary infections as well. Lung parenchymal findings in HRCT can thus be taken not to be disease-specific in NE and HRCT is useful only for scientific purposes.

    Computer vision technology has been widely used for blind assistance, such as navigation and wayfinding. However, few camera-based systems are developed for helping blind or visually-impaired people to find daily necessities. In this paper, we propose a prototype system of blind-assistant object finding by camera-based network and matching-based recognition. We collect a dataset of daily necessities and apply Speeded-Up Robust Features (SURF) and Scale Invariant Feature Transform (SIFT) feature descriptors to perform object recognition. Experimental results demonstrate the effectiveness of our prototype system.

    Protein-protein interactions (PPIs) play fundamental roles in nearly all biological processes, and provide major insights into the inner workings of cells. A vast amount of PPI data for various organisms is available from BioGRID and other sources. The identification of communities in PPI networks is of great interest because they often reveal previously unknown functional ties between proteins. A large number of global clustering algorithms have been applied to protein networks, where the entire network is partitioned into clusters. Here we take a different approach by looking for local communities in PPI networks. We develop a tool, named Local Protein Community Finder, which quickly finds a community close to a queried protein in any network available from BioGRID or specified by the user. Our tool uses two new local clustering algorithms Nibble and PageRank-Nibble, which look for a good cluster among the most popular destinations of a short random walk from the queried vertex. The quality of a cluster is determined by proportion of outgoing edges, known as conductance, which is a relative measure particularly useful in undersampled networks. We show that the two local clustering algorithms find communities that not only form excellent clusters, but are also likely to be biologically relevant functional components. We compare the performance of Nibble and PageRank-Nibble to other popular and effective graph partitioning algorithms, and show that they find better clusters in the graph. Moreover, Nibble and PageRank-Nibble find communities that are more functionally coherent. The Local Protein Community Finder, accessible at http://xialab.bu.edu/resources/lpcf, allows the user to quickly find a high-quality community close to a queried protein in any network available from BioGRID or specified by the user.

    To evaluate the ultrasonographic findings of lateral epicondylitis and their relationship with clinical outcome. The findings of ultrasonographic examinations of eighteen elbow joints in 15 patients (M:F=5:10; age:38-65(mean, 47.6) years) with lateral epicondylitis were reviewed. Two patients underwent surgery, two were not treated, and the remaining 11 were treated conservatively. Symptomatic improvement was noted 1 week after conservative treatment in two cases, at 2 weeks in five cases, at 3 weeks in three cases, and at 5 weeks in one case. With patients in the 90 degree flexed elbow position and in a supinated wrist, weexamined the extensor carpi radialis brevis (ECRB) tendon around the lateral epicondyle using ultrasound equipment with a 7-11 MHz linear transducer. The findings were assessed in terms of swelling of the tendon, changes in its echotexture, the presence of calcification of cystic degeneration, loss of the hypoechoic band between the tendon and bony cortex of the lateral epicondyle, cortical irregularity of the lateral epicondyle, and fluid collection around the tendon. Any relationships between each ultrasonographic finding and the treatment interval after which symptomatic improvement was noted were evaluated. In the 18 joints, change was heterogeneous hypoechogenicity in 13, and heterogeneous mixed echogenicity in three. Other ultrasonographic findings were swelling of the tendon in ten cases, loss of the hypoechoic band in 14, cortical irregularity in five, calcification in four, cystic degeneration in nine, and fluid collection around the tendon in four. In patients treated conservatively, there was no statistically significant difference between each ultrasonographic finding and the treatment interval after which symptomatic improvement was noted. Ultrasonography can be used to assess changes in the ECRB tendon and lateral epicondyle occurring in lateral epicondylitis, but fails to provide information on the rapidity of symptomatic

    To evaluate the CT and MRI findings of neurosyphilis. We retrospectively reviewed the CT and MR imaging findings in five patients with intracranial neurosyphilis confirmed by CSF, VDRL, TPHA, and clinical follow-up. MR imaging was performed in all five cases, and CT in two. The MRI and CT findings of intracranial neurosyphilis included infarction (n=3), focal inflammation (n=1) and encephalopathy (n=1). There was a total of ten infaretions : three of the basal ganglia, two each of the frontal lobe, watershed zone, and cerebellum, and one of the occipital lobe. Intaretion was most common in MCA territory (n=9; 50%), followed by the watershed zone (16.6%), posterior cerebral artery territory (16.6%), and posterior inferior cerebellar artery territory (11.1%). The size of the lesion varied from 1cm to larger than one lobe. One patient showed diffuse high signal intensity in the left temporal lobe, but on follow-up MRI, this had resolved. The most common finding of neurosyphilis, as seen on MRI and CT, was infarction in middle cerebral arterial territory

    To describe the radiologic findings of pulmonary endometriosis. This study involved five patients with catamenial hemoptysis diagnosed as pulmonary endometriosis. All cases were diagnosed on the basis of bronchoscopic abnormalities. In one patient, endometrial glandular cells were seen on transthoracic fine needle aspiration biopsy. In three, hemoptysis ceased after Danazol treatment. The pattern, location and number of parenchymal abnormalities and the presence or absence of pleural lesion were analyzed retrospectively on plain chest radiographs (n=3D5) and CT scans(n=3D5). Follow-up study for each menstrual period was performed in two cases and changes from the initial lesion were assessed. Plain chest radiographic findings showed focal ground-glass opacity in three cases;two were in the right lung and one in the left. CT findings included ground-glass attenuation (n=3D3) and a mixed pattern of ground-glass attenuations and consolidations(n=3D2). Sites were single in four cases, and in one case, there were two; thus there were in all six lesions. Five of these were located in the right lung and subpleural region, continving to the pleura. Pleural lesion was not detected on either chest radiographs or CT scans. Follow-up CT scans (n=3D2) showed a similar lesion at the same site. In patient with repeated catamenial hemoptysis, CT may be helpful for the diagnosis of pulmonary endometriosis by exclusion of other diseases.=20

    To evaluate the findings on chest CTs in 16 patients (8 men and 8 women) with laryngotracheobronchial papillomatosis. Methods: This was a retrospective study involving patients ranging from 2 to 72 years of age. The evaluation of the CT scans was independently performed by two observers, and discordant results were resolved by consensus. The inclusion criteria were presence of abnormalities on the CT scans, and the diagnosis was confirmed by anatomopathological examination of the papillomatous lesions. Results: The most common symptoms were hoarseness, cough, dyspnea, and recurrent respiratory infections. The major CT findings were nodular formations in the trachea, solid or cavitated nodules in the lung parenchyma, air trapping, masses, and consolidation. Nodular formations in the trachea were observed in 14 patients (87.5%). Only 2 patients had lesions in lung parenchyma without tracheal involvement. Only 1 patient had no pulmonary dissemination of the disease, showing airway involvement only. Solid and cavitated lung nodules were observed in 14 patients (87.5%) and 13 (81.2%), respectively. Masses were observed in 6 patients (37.5%); air trapping, in 3 (18.7%); consolidation in 3 (18.7%); and pleural effusion, in 1 (6.3%). Pulmonary involvement was bilateral in all cases. Conclusions: The most common tomography findings were nodular formations in the trachea, as well as solid or cavitated nodules and masses in the lung parenchyma. Malignant transformation of the lesions was observed in 5 cases. (author)

    To describe the radiologic findings of pulmonary endometriosis. This study involved five patients with catamenial hemoptysis diagnosed as pulmonary endometriosis. All cases were diagnosed on the basis of bronchoscopic abnormalities. In one patient, endometrial glandular cells were seen on transthoracic fine needle aspiration biopsy. In three, hemoptysis ceased after Danazol treatment. The pattern, location and number of parenchymal abnormalities and the presence or absence of pleural lesion were analyzed retrospectively on plain chest radiographs (n=3D5) and CT scans(n=3D5). Follow-up study for each menstrual period was performed in two cases and changes from the initial lesion were assessed. Plain chest radiographic findings showed focal ground-glass opacity in three cases;two were in the right lung and one in the left.

    The purpose of this study was to analyze the ultrasonographic (USG) findings of Kikuchi cervical lymphadenopathy in pediatric patients. Between April 2007 and September 2016, 84 children (42 male and 42 female; mean±standard deviation age, 12.9±3.2 years; range, 5 to 18 years) confirmed with Kikuchi disease were enrolled. Clinical findings and USG findings of Kikuchi cervical lymphadenopathy were retrospectively reviewed. Localized symptoms, systemic symptoms, and laboratory findings including the white blood cell count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were analyzed. An analysis of the USG findings included evaluation of the location, size, and presence of intranodal abscess; intranodal calcification; perinodal fat swelling; localized fluid collection; and loss of nodal echogenic hilum. Among the patients, 49 (58%) showed localized tenderness at the cervical lymphadenopathy. Fever was present in 55 (66%), while 27 (32%) had prolonged fever. Of 74 with lab results, 54 (73%) had leukopenia but none had leukocytosis. Among the same 74, there was a high ESR (>50 mm/hr) in 10 (14%) and a high CRP level (>5 mg/dL) in seven (9%). The USG findings of most of the patients (n=72, 86%) showed unilateral neck involvement, especially in the left side neck (45 of 72, 63%). The most common site of Kikuchi lymphadenopathy involvement was the area at cervical lymph node level V, at the posterior triangle (n=77, 92%). Conglomerated nodal distribution (n=57, 68%), preserved central nodal echogenic hilum (n=84, 98%), and perinodal fat swelling (n=55, 65%) were common USG findings in the children with Kikuchi. In addition, multiple cervical lymph nodes showed a relatively even size distribution (n=73, 87%). The common USG findings of Kikuchi disease in the pediatric population of our study were multiple conglomerated unilateral cervical lymphadenopathy showing perinodal fat swelling and even size distribution.

    The Silicon Vertex Detector (SVD) of the Belle II experiment is a newly developed device with four measurement layers. Track finding in the SVD will be done both in conjunction with the Central Drift Chamber and in stand-alone mode. The reconstruction of very-low-momentum tracks in stand-alone mode is a big challenge, especially in view of the low redundancy and the large expected background. We describe an approach for track finding in this domain, where a cellular automaton and a Kalman filter is combined with a Hopfield network which finds an optimal subset of non-overlapping tracks. We present results on simulated data and evaluate them in terms of efficiency and purity.

    To evaluate MR findings of soft tissue masses in extremities and to find the helpful findings of distinguish benignity from malignancy, 28 soft tissue masses (22 benign and 6 malignant) in extremities were reviewed. TI-weighted, proton density, T2-weighted and Gd-DTPA enhanced images were obtained. MR images allowed a specific diagnosis in large number of benign masses, such as hemangioma(8/9), lipoma(2/2), angiolipoma(1/1), epidermoid cyst(2/2), myositis ossificans(1/1), synovial chondromatosis(1/1) and pigmented villonodular synovitis(1/2). Specific diagnosis was difficult in the rest of the masses including malignancy. However, inhomogeneous signal intensities with necrosis and inhomogeneous enhancement may suggest malignant masses.

    Full text: Neuroimaging methods are of great importance for the differential diagnostic delimitation of movement disorders associated with structural damage (neoplasms, ischemic lesions, neuroinfections) from those associated with specific pathophysiological mechanisms (dysmetabolic disorders, neurotransmitter disorders). Learning objective: Presentation of typical imaging findings contributing to nosological differentiation in groups of movement disorders with similar clinical signs. In this presentation are discussed neuroimaging findings in Parkinson‘s disease, atypical parkinsonian syndromes (multiple system atrophy, progressive supranuclear palsy, corticobasal degeneration), parkinsonism in genetically mediated diseases (Wilson’s disease, pantothenate kinase-associated neurodegeneration – PKAN), vascular parkinsonism, hyperkinetic movement disorders (palatal tremor, Huntington‘s chorea, symptomatic chorea in ischemic stroke and diabetes, rubral tremor, ballismus, hemifacial spasm). Contemporary neuroimaging methods enable support for diagnostic and differential diagnostic precision of a number of hypo- and hyperkinetic movement disorders, which is essential for neurological clinical practice

    Francisella tularensis, the causative organism in Tularemia, is a relatively rare disease. There are a few radiological clues to elucidate its presence when suspicion arises. There should be strong consideration for Tularemia in the differential of any patient with its classic symptoms, diffuse cervical lymphadenopathy with evidence of necrosis, and enlarged adenoids. Ultrasound may demonstrate suppurative lymphadenopathy suggestive of infection, as in the case presented. CT often will demonstrate the extent of lymphadenopathy. On chest radiography, tularemia pneumonia is often the presenting finding, which may demonstrate bilateral or lobar infiltrates. Additionally, hilar lymphadenopathy and pleural effusions are often associated findings. Cavitary lesions may be present, which are better delineated on CT scan. We present a case of a 7-year-old male who presented with a painful right-sided palpable neck mass for 9 days, who was diagnosed with Tularemia after numerous admissions.

    Much has been written regarding the incidence, types, importance and management of abdominal CT incidental findings in adults, but there is a paucity of literature on incidental findings in children. We sought to determine the prevalence and characteristics of extra-appendiceal and incidental findings in pediatric abdominal CT performed for suspected appendicitis. A retrospective review was performed of abdominal CT for suspected appendicitis in a pediatric emergency department from July 2010 to June 2012. Extra-appendiceal findings were recorded. Any subsequent imaging was noted. Extra-appendiceal findings were divided into incidental findings of doubtful clinical significance, alternative diagnostic findings potentially providing a diagnosis other than appendicitis explaining the symptoms, and incidental findings that were abnormalities requiring clinical correlation and sometimes requiring further evaluation but not likely related to the patient symptoms. One hundred sixty-five children had abdominal CT for suspected appendicitis. Seventy-seven extra-appendiceal findings were found in 57 (34.5%) patients. Most findings (64 of 77) were discovered in children who did not have appendicitis. Forty-one of these findings (53%) could potentially help explain the patient's symptoms, while 30 of the findings (39%) were abnormalities that were unlikely to be related to the symptoms but required clinical correlation and sometimes further work-up. Six of the findings (8%) had doubtful or no clinical significance. Extra-appendiceal findings are common in children who undergo abdominal CT in the setting of suspected appendicitis. A significant percentage of these patients have findings that help explain their symptoms. Knowledge of the types and prevalence of these findings may help radiologists in the planning and interpretation of CT examinations in this patient population. (orig.)

    The authors of national guidelines emphasize the use of history and examination findings to diagnose community-acquired pneumonia (CAP) in outpatient children. Little is known about the interrater reliability of the physical examination in children with suspected CAP. This was a prospective cohort study of children with suspected CAP presenting to a pediatric emergency department from July 2013 to May 2016. Children aged 3 months to 18 years with lower respiratory signs or symptoms who received a chest radiograph were included. We excluded children hospitalized ≤14 days before the study visit and those with a chronic medical condition or aspiration. Two clinicians performed independent examinations and completed identical forms reporting examination findings. Interrater reliability for each finding was reported by using Fleiss' kappa (κ) for categorical variables and intraclass correlation coefficient (ICC) for continuous variables. No examination finding had substantial agreement (κ/ICC > 0.8). Two findings (retractions, wheezing) had moderate to substantial agreement (κ/ICC = 0.6-0.8). Nine findings (abdominal pain, pleuritic pain, nasal flaring, skin color, overall impression, cool extremities, tachypnea, respiratory rate, and crackles/rales) had fair to moderate agreement (κ/ICC = 0.4-0.6). Eight findings (capillary refill time, cough, rhonchi, head bobbing, behavior, grunting, general appearance, and decreased breath sounds) had poor to fair reliability (κ/ICC = 0-0.4). Only 3 examination findings had acceptable agreement, with the lower 95% confidence limit >0.4: wheezing, retractions, and respiratory rate. In this study, we found fair to moderate reliability of many findings used to diagnose CAP. Only 3 findings had acceptable levels of reliability. These findings must be considered in the clinical management and research of pediatric CAP. Copyright © 2017 by the American Academy of Pediatrics.

    Recurrent pyogenic cholangitis is characterized clinically by recurrent attacks of right upper abdominal pain, fever and jaundice, and pathologically by chronic inflammation of the bile ducts with or without pigment bile duct stones. We analyzed the CT findings of 33 cases with recurrent pyogenic cholangitis. Twenty-four cases were confirmed by operation, and 9 cases were diagnosed clinically and cholangiographically. The CT findings of recurrent pyogenic cholangitis were dilatation of the intrahepatic ducts (n = 30), dilatation of the extrahepatic ducts (n = 24) intrahepatic stones (n = 16), extrahepatic stones (n = 12), stricture of the bile ducts (n = 10), wall enhancement of the bile ducts (n = 8), gallstones (n = 8), segmental atrophy of the liver (n = 7), pneumobilia (n = 4), abscess (n = 3), and segmental enhancement (n = 1) of the liver. A CT is considered helpful when sectional imaging is needed, but sonographic findings are equivocal or not confirmative; space-occupying lesions complicated with recurrent pyogenic cholangitis: hepatic resection is planned; and imaging guidance is needed for complex drainage procedures

    Femoroacetabular impingement syndrome (FAI) is a pathologic entity which can lead to chronic symptoms of pain, reduced range of motion in flexion and internal rotation, and has been shown to correlate with degenerative arthritis of the hip. History, physical examination, and supportive radiographic findings such as evidence of articular cartilage damage, acetabular labral tearing, and early-onset degenerative changes can help physicians diagnose this entity. Several pathologic changes of the femur and acetabulum are known to predispose patients to develop FAI and recognition of these findings can ultimately lead to therapeutic interventions. The two basic mechanisms of impingement - cam impingement and pincer impingement - are based on the type of anatomic anomaly contributing to the impingement process. These changes can be found on conventional radiography, MR imaging, and CT examinations. However, the radiographic findings of this entity are not widely discussed and recognized by physicians. In this paper, we will introduce these risk factors, the proposed supportive imaging criteria, and the ultimate interventions that can help alleviate patients' symptoms. (orig.)

    This study analyses clinical data, EEC and X-ray findings of 102 stationary examined migraine patients, 62 of whom suffered from migraine accompagnee. Sex distribution, age at onset of disease, hereditary disease disposition and EEC findings largely correspond to the data given in literature. As it had been expected, the X-ray images of the skull and the cerebral angiographies performed in 46 patients suffering from migraine accompagnee did not show any pathological findings. The X-ray images were compared with those taken of patients without migraine anamnesis in order to detect non-pathologic variations. Neither differences in the intensity of vascular and diplovenous marking could be found in the native images of the skull nor any variations of the circle of Willisi. The dependency of the posterior cerebral artery on the carotid circulation existing in 41% of the migraine accompagnee does not lead to any particular alteration of the accompanying symptoms and signs. The idea is discussed to divide the migraine syndrome into simple, focal and complicated migraine on the basis of a uniform pathogenesis. (orig./MG) [de

    The aim of this study was to assess high-resolution computed tomography (HRCT) findings of exogenous lipoid pneumonia. High-resolution computed tomography was obtained in 25 patients with proven exogenous lipoid pneumonia resulting from aspiration of squalene (derived from shark liver oil). Diagnosis was based on biopsy (n = 9), bronchoalveolar lavage (n = 8), or sputum cytology and clinical findings (n = 8). The clinical history of taking squalene was confirmed in all patients. The CT findings were classified into three patterns: diffuse ground-glass opacity, consolidation, and interstitial abnormalities. Distribution of the abnormalities, duration of taking squalene, predisposing factors for aspiration, and route of administration were analyzed. Ten patients showed diffuse ground-glass opacity pattern. Seven of 10 patients had predisposing conditions such as unconsciousness, pharyngeal dysmotility, or motor disturbances, and 6 patients had a recent history of taking large amount of squalene through nasal route. Seven patients who had consolidation pattern had a history of taking squalene for several months and did not have any predisposing factor. All of the 5 patients who had a pattern of interstitial abnormalities had a history of taking squalene longer than 1 year and showed segmental distribution of interstitial thickening with interposing ground-glass opacities. Three patients simultaneously had two different patterns at different lobes of the lung. The HRCT findings of lipoid pneumonia are ground-glass opacities, consolidation, and interstitial abnormalities. These HRCT findings with appropriate inquiries could be useful for diagnosis of exogeneous lipoid pneumonia. (orig.)

    To evaluate the mammographic and clinical findings of nonpalpable breast cancer. Materials and Methods : In 28 of 607 breast cancer patients examined between January 1994 and April 1997, lesions were nonpalpable. We retrospectively analyzed the mammographic, clinical and pathologic features of 25 patients (28 lesions) whose mammograms we obtained. Results : Among these 25 patients (28 lesions) screening was abnormal in 22; other symptoms were bloody nipple discharge(n=4), and nipple eczema(n=2). The patients were 34-62 (mean 52)years old. Invasive ductal carcinoma(n=13), DCIS(ductal carcinoma in situ, n-12), Paget's disease (n=2), and LCIS(lobular carcinoma in situ, n=1) were found during surgery. Six of 28 lesions(21%) showed evidence of axillary nodal metastasis;the majority arose from the upper outer quadrant of the breast (n=21). The mammographic findings were mass (50%), (and mass with microcalcification, 11%); microcalcification(29%); asymmetrical density(14%); and normal (7%). According to the mammographic density of breast parenchyma, the major finding in the low density group(N1+P1) was mass(9/9), and in the high density group(P2+DY) was microcalcification (12/19). Conclusion : The most common mammographic findings of nonpalpable breast cancer were mass (50%) and microcalcification(29%). Its features varied according to the mammographic density of breast parenchyma;mass was the main finding in the low density group and microcalcification in the high density group.

    2010-03-01

    Full Text Available Up to now, the G20 has supervised the process to revitalize the real economy affected by the Great Recession through fiscal stimuli and a very easy monetary policy, and to rescue the battered financial system by injecting capital into giant banks and firms. The G20 is now turning its attention to financial regulation, with the FSB as its main operational arm. The ideas that are being proposed stress the need for disincentives toward too much risk taking (more capital, higher liquidity, limits to remunerations and bonuses, etc., particularly by big and complex financial institutions that are likely to entail systemic risks. The paper maintains that, as the disincentive approach is insufficient to deter financial managers looking for power, some kind of segmentation needs to be introduced, as suggested by Paul Volcker.  JEL: E44, G1, G18, G28

    The web has become a primary information resource about illnesses and treatments for both medical and non-medical users. Standard web search is by far the most common interface to this information. It is therefore of interest to find out how well web search engines work for diagnostic queries and what factors contribute to successes and failures. Among diseases, rare (or orphan) diseases represent an especially challenging and thus interesting class to diagnose as each is rare, diverse in symptoms and usually has scattered resources associated with it. We design an evaluation approach for web search engines for rare disease diagnosis which includes 56 real life diagnostic cases, performance measures, information resources and guidelines for customising Google Search to this task. In addition, we introduce FindZebra, a specialized (vertical) rare disease search engine. FindZebra is powered by open source search technology and uses curated freely available online medical information. FindZebra outperforms Google Search in both default set-up and customised to the resources used by FindZebra. We extend FindZebra with specialized functionalities exploiting medical ontological information and UMLS medical concepts to demonstrate different ways of displaying the retrieved results to medical experts. Our results indicate that a specialized search engine can improve the diagnostic quality without compromising the ease of use of the currently widely popular standard web search. The proposed evaluation approach can be valuable for future development and benchmarking. The FindZebra search engine is available at http://www.findzebra.com/. Copyright © 2013 Elsevier Ireland Ltd.

    55 out of 62 patients with cerebral infarction were investigated in terms of CT scan findings, angiographic findings, and clinical symptoms. The results obtained were as follows: 1) The low-density areas of the CT scan findings were classified into the following four types: large hemispheric or lobular --Type I; wedge-shaped --Type II; small --Type III; and lacunar low-density area. --Type IV. 2) Almost all patients with angiographically occlusive findings showed low-density areas of Type I; however, one patient with ICA occlusion revealed only a lacunar low-density area. 3) The patients with lacunar low-density areas showed an angiographically delayed filling of the angular artery and posterior parietal artery of the middle cerebral artery. 4) The relationship between the types of low-density areas and the clinical conscious disorders was not clear. On the other hand, the patients with Type I low-density areas almost all had motor disturbances, while patients with other types of low-density areas showed only 60 - 70% motor disturbances. 5) In patients with speech disorders, total aphasia cases were found in patients with large hemispheric low-density areas on the left side. Although, motor aphasia cases were seen in patients with various low-density areas on the left inferior frontal and precentral gyri, dysarthria cases were found in the patients with several low-density areas on both sides. 6) The localization of lacunar low-density areas seemed to be near the caudate nucleus on the right side and in the putaminal regions on the left side. The mean and the standard deviation of CT numbers in the lacunar low-density areas showed higher values on the right side than on the left side. (author)

    Alkaptonuria is a rare disease with autosomal recessive inheritance and variable expression. The weight-bearing joint involvement and spondylitis-like vertebral changes occur only after the 3rd decade. Musculoskeletal ultrasonographic findings in alkaptonuria were only rarely described, consisting mainly into enthesopathy and non-synovial tendon degeneration. We present the case of a 50 years old man with alkaptonuria and discuss the ultrasonographic findings and the relationship of the disease with chondrocalcinosis. The tendinous and synovial aspect may be peculiar and it could therefore allow recognition and screening for alkaptonuria, along with clinical and radiologic data.

    To evaluate the usefulness of ultrasonographic findings of the common extensor and flexor tendon in evaluation of patients with lateral and medial epicondylitis. Thirty eight elbows from twenty four patients (mean age=45.2 years) were included. Ultrasonographic examination was performed to evaluate lateral or medial epicondylitis. Epicondylitis was divided into five groups according to the severity of disease: 1) normal, 2) tendinopathy, 3) tendinopathy with a partial tear, partial tear and 4) complete tear. Change in the size of a tendon, bony change of the epicondylitis, presence or absence of calcification or echogenic foci in the common tendon and hypervascularity for each categories were also assessed. In addition, these lesions were divided into the superficial and deep according to the location of lesions. According to the severity, there were 15 cases of normal, 13 tendinopathies, 8 tendinopathies with a partial tear, 2 partial tears and 0 complete tear. Bony change was seen only in tendinopathy, tendinopathy with partial tear and partial tear. Calcification or echogenic foci were only observed in cases with tendinopathy and tendinopathy with partial tear. Hypervascularity was only seen in one case of tendinopathy. With thorough understanding of ultrasonographic findings of epicondylitis, ultrasonographic examination can be especially useful and effective in evaluating the severity and location of lesions.

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

    Dysautonomia is caused by degeneration of the autonomic ganglia. Failure of the autonomic system affecting the gastrointestinal and urinary tracts can cause oesophageal distension and/or dysfunction, gastric and bowel distension and hypomotility, and urinary bladder distension. The aim of this retrospective study was to describe diagnostic imaging findings in cats with dysautonomia. Common findings were megaoesophagus and/or oesophageal dysfunction, gastric distension and signs of intestinal ileus. Associated aspiration pneumonia and megacolon appeared less commonly. Although diagnostic imaging findings are not specific for this disease, if findings in multiple systems are detected, along with consistent clinical signs and neurological deficits, dysautonomia should be considered among the differential diagnosis.

    CTT was performed in 14 children/adolescents with juvenile ceroid lipofuscinosis (JNCL) at different stages of the disease. CTT was normal in 7 patients; mildly abnormal in 3, clearly abnormal in another 3 and severely abnormal in 1 patient. Characteristic findings were symmetrical enlargement of subarachnoid spaces and of the lateral and third ventricles. White matter showed no changes in density. In later stages also the fourth ventricle was enlarged and cerebellar atrophy was seen. CTT findings were not closely correlated with onset and/or severity of the neurological abnormalities. CTT findings were positively correlated with age of the patients: CTT was usually normal if patients were less than 10 years old, and usually abnormal if patients were more than 14 years old.

    Pericardial fat necrosis is an infrequent cause of acute chest pain and this can mimic acute myocardial infarction and acute pericarditis. We describe here a patient with the magnetic resonance imaging (MRI) findings of pericardial fat necrosis and this was correlated with the computed tomography (CT) findings. The MRI findings may be helpful for distinguishing pericardial fat necrosis from other causes of acute chest pain and from the fat-containing tumors in the cardiophrenic space of the anterior mediastinum.

    Two-dimensional generalization of the original peak finding algorithm suggested earlier is given. The ideology of the algorithm emerged from the well-known quantum mechanical tunneling property which enables small bodies to penetrate through narrow potential barriers. We merge this 'quantum' ideology with the philosophy of Particle Swarm Optimization to get the global optimization algorithm which can be called Quantum Swarm Optimization. The functionality of the newborn algorithm is tested on some benchmark optimization problems

    Aim: To describe serial changes in brain magnetic resonance imaging (MRI) in acute human infection from two outbreaks of Hendra virus (HeV), relate these changes to disease prognosis, and compare HeV encephalitis to reported cases of Nipah virus encephalitis. Materials and methods: The MRI images of three human cases (two of which were fatal) of acute HeV meningoencephalitis were reviewed. Results: Cortical selectivity early in the disease is evident in all three patients, while deep white matter involvement appears to be a late and possibly premorbid finding. This apparent early grey matter selectivity may be related to viral biology or ribavirin pharmacokinetics. Neuronal loss is evident at MRI, and the rate of progression of MRI abnormalities can predict the outcome of the infection. In both fatal cases, the serial changes in the MRI picture mirrored the clinical course. Conclusion: This is the first comprehensive report of serial MRI findings in acute human cerebral HeV infection from two outbreaks. The cortical selectivity appears to be an early finding while deep white matter involvement a late, and possibly premorbid, finding. In both fatal cases, the serial changes in MRI mirrored the clinical course.

    Full Text Available Myeloproliferative neoplasms (MPN arise from genetic deficiencies at the level of pluripotent stem cells. Each of these neoplasms is a clonal stem cell disorder with specific phenotypic, genetic and clinical properties. Age is one of the most important factors in the development of symptoms and complications associated with MPNs.High white blood cell counts in chronic myelocytic leukemia also known as leukocytosis may lead to central nervous system findings. Tumors developing outside the bone marrow named as extramedullary myeloid tumors (EMMT could be detected at the initial diagnosis or during the prognosis of the disease, which may cause neurological symptoms due to pressure of leukemic cell mass on various tissues along with spinal cord. Central nervous system involvement and thrombocytopenic hemorrhage may lead to diverse neurological symptoms and findings.Transient ischemic attack and thrombotic stroke are the most common symptoms in polycythemia vera. Besides thrombosis and hemorrage, transformation to acute leukemia can cause neurological symptoms and findings. Transient ischemic attack, thrombotic stroke and specifically hemorrage can give rise to neurological symptoms similar to MPN in essential thrombocytosis.Extramedullary hematopoiesis refers to hematopoietic centers arise in organ/tissues other than bone marrow in myelofibrosis. Extramedullar hematopoietic centers may cause intracranial involvement, spinal cord compression, seizures and hydrocephalia. Though rare, extramedullary hematopoiesis can be detected in cranial/spinal meninges, paraspinal tissue and intracerebral regions. Extramedullary hematopoiesis has been reported in peripheral neurons, choroid plexus, pituitary, orbits, orbital and lacrimal fossa and in sphenoidal sinuses. [Cukurova Med J 2013; 38(2.000: 157-169

    1987-01-01

    Usual chest radiographic findings in pulmonary tuberculosis are well described in radiologic literatures for both primary and postprimary phases of disease. During the last decade, many authors have enumerated the unusual manifestations of pulmonary tuberculosis in adult population. These unusual findings usually have been involved in the frequent failure of both radiologist and clinician to recognize that tuberculosis could be the cause of a abnormal chest radiograph in patients who are finally and surprisingly proven to have tuberculosis. Authors have evaluated 249 patients who were admitted and newly proven to have adult-onset pulmonary tuberculosis at Chung-Ang University Hospital from January, 1985 to December, 1986. Unusual findings were noted in 76 (30.5%) of the 249 patients with adult-onset pulmonary tuberculosis. These unusual findings most frequently could be seen in 3rd decades and showed no sex difference in incidence. A broad spectrum of abnormal findings including usual and unusual abnormalities were procedure by adult-onset pulmonary tuberculosis. The unusual radiographic findings were arbitrarily classified. Pleural effusion without parenchymal disease (10.0%), unusual location of infiltrate (5.6%) and atelectasis (3.2%) were relatively common. Hilar and / or mediastinal lymphnode enlargement (1.6%), cavity without parenchymal infiltrates (1.6%), septic lung-like infiltrates (1.6%), completely clear lungs (1.2%), miliary infiltrates (1.2%), fibrocalcific scar-like infiltrates (1.2%), masslike density (1.2%) and rheumatoid lung-like infiltrates (1.2%) were occasionally noted. Pneumothorax without parenchymal disease (0.4%) and bron chocutaneous fistula (0.4%) are. The recognition of these unusual findings could further improve the detection and diagnosis of adult-onset pulmonary tuberculosis

    Topographical disorientation is identified as a condition in which patients are unable to find their way in familiar surroundings, such as their home neighborhood or the admitting hospital after the onset of illness. I proposed to classify topographical disorientation into two categories: agnosia for streets (landmark agnosia) and defective root finding (heading disorientation). Patients with agnosia for streets are unable to identify familiar buildings and landscapes. They can, however, morphologically perceive them and remember their way around familiar areas. The lesions are located in the right posterior part of the parahippocampus gyrus, anterior half of the lingual gyrus and adjacent fusiform gyrus. Clinical findings and functional imaging studies suggest that these regions play a crucial role in the interaction between the visual information of streets and memories of them, which are thought to be retained in the right anterior part of the temporal lobe. In particular, the posterior part of the parahippocampus gyrus is critical for the acquisition of novel information. On the other hand, patients with defective root finding can identify familiar streets, but cannot remember their own location or positional relation between two points within a comparatively wide range not surveyable at one time. The lesions are located in the right retrosplenial cortex (Areas 29, 30), posterior cingulate cortex (Areas 23, 31) and precuneus. Clinical findings and functional imaging studies suggest that these regions are involved in the orientation function for navigating in wide spaces. In particular, the retrosplenial cortex is critical for encoding novel information.

    Scurvy has become very rare in the modern world. The incidence of scurvy in the pediatric population is extremely low. In the pediatric population, musculoskeletal manifestations are more common and multiple subperiosteal hematomas are an important indicator for the diagnosis of scurvy. Although magnetic resonance imaging findings of scurvy are well described in the literature, to our knowledge, ultrasound findings have not yet been described. In this article, we report a case of scurvy with associated magnetic resonance imaging and ultrasound findings. (orig.)

    Empirical studies on the determinants of bridge employment have often neglected the fact that some retirees may be unsuccessful in finding a bridge job. We present an integrative framework that emphasizes socioeconomic factors, health status, social context, and psychological factors to explain why some people fully retired after career exit, some participated in bridge jobs, while others unsuccessfully searched for one. Using Dutch panel data for 1,221 retirees, we estimated a multinomial logit model to explain participation in, and unsuccessful searches for, bridge employment. About 1 in 4 retirees participated in bridge employment after retirement, while 7% searched unsuccessfully for such work. Particularly those who experienced involuntary career exit were found to have a higher probability of being unsuccessful at finding bridge employment. The current study provides evidence for the impact of the social context on postretirement work and suggests a cumulative disadvantage in the work domain in later life. © The Author 2015.

    Full Text Available Background. To report a case of acute zonal occult outer retinopathy (AZOOR with atypical electrophysiology findings. Case Presentation. A 23-year-old-female presented with visual acuity deterioration in her right eye accompanied by photopsia bilaterally. Corrected distance visual acuity at presentation was 20/50 in the right eye and 20/20 in the left eye. Fundus examination was unremarkable. Visual field (VF testing revealed a large scotoma. Pattern and full-field electroretinograms (PERG and ERG revealed macular involvement associated with generalized retinal dysfunction. Electrooculogram (EOG light rise and the Arden ratio were within normal limits bilaterally. The patient was diagnosed with AZOOR due to clinical findings, visual field defect, and ERG findings. Conclusion. This is a case of AZOOR with characteristic VF defects and clinical symptoms presenting with atypical EOG findings.

    CT scans were obtained in 45 patients with bronchial asthma including 23 patients during asthmatic attack. CT findings were as follows. 1) In all cases, thickening of bronchial wall throughout from central to peripheral bronchi and without tapering and/or slight swelling of bronchovascular bundles were observed. 2) Characteristics findings in 23 patients with asthmatic attack, lobular and multilobular high attenuation area were observed in 17 patients (74%) and nonhomogeneous attenuation in lung fields were noticed in 13 patients (57%). 3) Multiple centrilobular sized high attenuation area were observed in 23 patients, but it was difficult to differenciation whether these findings were due to tiny nodules or to small vessels. In conclusion, further studies are needed to know which pathomorphological and/or pathophysiological conditions are underlying these CT findings. (author)

    The symptoms and physical findings of intersection syndrome have been well described in the clinical medical literature. However, the magnetic resonance imaging (MRI) findings in patients with intersection syndrome of the forearm have only recently been described in a small number of patients. We review our experience with imaging of intersection syndrome, describe previously unreported MRI findings, and emphasize modifications to MRI protocols for its evaluation. Institutional review board approval was obtained for this retrospective review of patients with MRI findings consistent with intersection syndrome of the forearm during the period from January 2004 to September 2006. Six patients were identified, three males and three females, with an average age of 39.3 years. The MRI examinations were reviewed to assess signal abnormalities within and adjacent to the first and second dorsal extensor tendon compartments (DETC): tendinosis, peritendinous edema or fluid, muscle edema, subcutaneous edema, and juxtacortical edema. The overall longitudinal extent of signal alterations was measured as well as the distance from Lister's tubercle to the crossover of the first and second DETC. Review of the MRIs showed increased intrasubstance tendon signal suggesting tendinosis in two of the six patients, peritendinous edema or fluid in all six patients, muscle edema in five of the six patients, and subcutaneous edema in three of the six patients. Juxtacortical edema was seen in one patient. Peritendinous edema or fluid extended distally beyond the radiocarpal joint in three of the six patients. The average distance from Lister's tubercle to the crossover of the first and second DETC was 3.95 cm, in keeping with recently published data. Intersection syndrome is an uncommon MRI diagnosis. In addition to the previously described MRI findings of edema adjacent to the first or second DETC, possibly with proximal extension and subcutaneous edema, we have identified additional

    1992-01-01

    CT scans in 11 cases of chronic eosinophilic pneumonia (CEP) were reviewed. Peripheral dense opacities suggesting air-space consolidation were the most peculiar findings seen in 9 patients on CT, but 7 on chest radiographs. Five patients showed broad plate-like opacities parallel to the pleura, which were the results of resolution from the periphery of the consolidation. Diffuse interstitial opacities suggesting alveolitis were the predominant finding in 3 patients, one of which also had peripheral air-space consolidation. Follow-up CT showed no residual abnormality except one who had DIP concomitant with CEP. CT scans are useful tool for both diagnosis and follow-up of CEP. (author)

    Full Text Available In occupational and environmental health research, individual, group and community research participants have a unique and vested interest in the research findings. The ethical principles of autonomy, non-maleficence and beneficence are helpful in considering the ethical issues in the disclosure of research findings in occupational and environmental health research. Researchers need to include stakeholders, such as groups and communities, in these discussions and in planning for the dissemination of research findings. These discussions need to occur early in the research process.

    Membranous lipodystrophy, also known as Nasu-Hakola disease, is a rare hereditary condition with manifestations in the nervous and skeletal systems. The radiographic appearance of skeletal lesions has been well described in the literature. However, CT and MRI findings of lesions in the bone have not been documented to date. This report describes the radiographic, CT, MRI, and histopathologic skeletal findings in a case of membranous lipodystrophy. With corroborative pathologic findings, a diagnosis of membranous lipodystrophy on imaging allows for appropriate clinical management of disease manifestations. (orig.)

    2003-01-01

    Full Text Available OBJECTIVE: Noonan syndrome is a multiple congenital anomaly syndrome, and bleeding diathesis is considered part of the clinical findings. The purpose of this study was to determine the frequency of hemostatic abnormalities in a group of Noonan syndrome patients. METHOD: We studied 30 patients with clinical diagnosis of Noonan syndrome regarding their hemostatic status consisting of bleeding time, prothrombin time, activated partial thromboplastin time and thrombin time tests, a platelet count, and a quantitative determination of factor XI. RESULTS: An abnormal laboratory result was observed in 9 patients (30%. Although coagulation-factor deficiencies, especially factor XI deficiency, were the most common hematological findings, we also observed abnormalities of platelet count and function in our screening. CONCLUSIONS: Hemostatic abnormalities are found with some frequency in Noonan syndrome patients (30% in our sample. Therefore, we emphasize the importance of a more extensive hematological investigation in these patients, especially prior to an invasive procedure, which is required with some frequency in this disorder.

    The peritoneal mesothelioma is a rare neoplasm which arises from the peritoneal lining of the abdomen, tending to spread along the peritoneal cavity and to invade abdominal organs. Authors report the CT findings of 4 patients with histologically proven peritoneal mesothelioma seen at Dongsan Medical Center, School of Medicine, Keimyung University. None of them had a history of exposure to asbestos and no clear etiologic factor could be determined in any patient. CT showed peritoneal and mesenteric thickenings in all cases, omental thickenings in 3 cases, peritoneal nodules, mesenteric masses or omental masses in 2 cases each other, bowel wall involvement in 1 case, and disproportionally small ascites in 2 cases. Distant hematogenous metastases to the liver and retroperitoneal lymph nodes were seen in 1 case. Our experience with 4 peritoneal mesotheliomas as well as a review of the recent imaging literature shows excellent correlation between computed tomography and the operitoneoscopic findings

    We report on the MRI findings in the vertebrae and surrounding soft tissues in two patients with the SAPHO syndrome (Synovitis, Acne, Pustulosis, Hyperostosis, Osteitis). The MRI findings include abnormal bone marrow signal, either focal or diffuse, of the vertebral bodies and posterior elements; hyperintense paravertebral soft tissue swelling and abnormal signal of the intervertebral discs. These changes are consistent with discitis and osteitis. (orig.) With 6 figs., 17 refs.

    To analyze the radiographic and HRCT findings of Pneumocystic carinii pneumonia. We reviewed the medical records and retrospectively analysed the chest radiographs(n=31) and HRCT scans(n=17) of 31 patients with Pneumocystis carinii pneumonia who had been followed up at our institute between, 1993 and March 1998. Pneumocystis carinii pneumonia was confirmed by cytologic evaluation of sputum stained with methenamine silver(n=25) or on the basis of clinical history(n=6). The study group included 17 men and 14 women aged 28-78(average, 53.6) years. Twenty-eight patients had underlying conditions such as hematologic diseases(n=13), AIDS(n=8), malignancy(n=2), DM(n=2) and malnutrition(n=1), and three were free from underlying diseases. Twenty patients had pure Pneumocystis carinii pneumonia and 11 had combined lung diseases, namely pulmonary tuberculosis(n=4), pulmonary metastasis(n=2), bacterial pneumonia(n=2), atypical mycobacterial infection(n=1), pulmonary edema(n=1), and Kaposi' s sarcoma(n=1). Chest radiographic findings of 20 cases of pure Pneumocystis carinii pneumonia included consolidation(n=12), linear-reticular opacity(n=8), ill defined haziness(n=7), and nodules(n=6), with bilaterality in is cases and zonal predominance in ten [central(n=5), lower(n=5)]. Ancillary findings included pleural effusion(n=10), cysts(n=5), lymphadenopathy(n=4) and pneumothorax(n=1). In two patients, findings were entirely normal. HRCT findings in ten cases of pure Pneumocystis carinii pneumonia included ground-glass opacity(n=6), consolidation(n=6), linear-reticular opacity(n=8), and nodules(n=5), with bilaterallity in seven cases and zonal predominance in five [central(n=5), lower(n=2)]. Ancillary findings among these cases included pleural effusion(n=4), lymphadenopathy(n=2), cysts(n=1), and pneumothorax(n=1). HRCT findings in seven cases of Pneumocystis carinii pneumonia combined with other lung diseases included nodules(n=6), ground-glass opacity(n=5), linear-reticular opacity

    To retrospectively determine the sensitivity and specificity of magnetic resonance (MR) imaging findings in patients with clinical athletic pubalgia, with either surgical or physical examination findings as the reference standard. Institutional review board approval was granted for this HIPAA-compliant study, and informed consent was waived. MR imaging studies in 141 patients (134 male patients, seven female patients; mean age, 30.1 years; range, 17-71 years) who had been referred to a subspecialist because of groin pain were reviewed for findings including hernia, pubic bone marrow edema, secondary cleft sign, and rectus abdominis and adductor tendon injury. MR imaging findings were compared with surgical findings for 102 patients, physical examination findings for all 141 patients, and MR imaging findings in an asymptomatic control group of 25 men (mean age, 29.8 years; range, 18-39 years). Sensitivity and specificity of MR imaging for rectus abdominis and adductor tendon injury were determined by using a chi(2) analysis, and significance of the findings was analyzed with an unpaired Student t test. Disease patterns seen at MR imaging were compared with those reported in the surgical and sports medicine literature. One hundred thirty-eight (98%) of 141 patients had findings at MR imaging that could cause groin pain. Compared with surgery, MR imaging had a sensitivity and specificity, respectively, of 68% and 100% for rectus abdominis tendon injury and 86% and 89% for adductor tendon injury. Injury in each of these structures was significantly more common in the patient group than in the control group (P pubalgia, including rectus abdominis insertional injury, thigh adductor injury, and articular diseases at the pubic symphysis (osteitis pubis).

    1993-08-01

    In the late eighties several reports have been published on climate change and sea level rise. In the meantime insights may have changed due to the availability of better and more observations and/or more advanced climate models. The aim of this report is to present the most recent findings with respect to climate change, in particular of sea level rise, storm surges and river peak flows. These climate factors are important for the safety of low-lying areas with respect to coastal erosion and flooding. In the first chapters a short review is presented of a few of the eighties reports. Furthermore, the predictions by state of the art climate models at that time are given. The reports from the eighties should be considered as 'old' information, whereas the IPCC supplement and work, for example, by Wigley should be considered as new information. To assess the latest findings two experts in this field were interviewed: dr J. Oerlemans and dr C.J.E. Schuurmans, a climate expert from the Royal Netherlands Meteorological Institute (KNMI). Their views are presented together with results published in recent papers on the subject. On the basis of this assessment, the report presents current knowledge regarding predictions of climate change (including sea-level rise) over the next century, together with an assessment of the uncertainties associated with these predictions. 14 figs., 11 tabs., 24 refs

    Juvenile localized scleroderma comprises a group of autoimmune conditions often characterized clinically by an area of skin hardening. In addition to superficial changes in the skin and subcutaneous tissues, juvenile localized scleroderma may involve the deep soft tissues, bones and joints, possibly resulting in functional impairment and pain in addition to cosmetic changes. There is literature documenting the spectrum of findings for deep involvement of localized scleroderma (fascia, muscles, tendons, bones and joints) in adults, but there is limited literature for the condition in children. We aimed to document the spectrum of musculoskeletal magnetic resonance imaging (MRI) findings of both superficial and deep juvenile localized scleroderma involvement in children and to evaluate the utility of various MRI sequences for detecting those findings. Two radiologists retrospectively evaluated 20 MRI studies of the extremities in 14 children with juvenile localized scleroderma. Each imaging sequence was also given a subjective score of 0 (not useful), 1 (somewhat useful) or 2 (most useful for detecting the findings). Deep tissue involvement was detected in 65% of the imaged extremities. Fascial thickening and enhancement were seen in 50% of imaged extremities. Axial T1, axial T1 fat-suppressed (FS) contrast-enhanced and axial fluid-sensitive sequences were rated most useful. Fascial thickening and enhancement were the most commonly encountered deep tissue findings in extremity MRIs of children with juvenile localized scleroderma. Because abnormalities of the skin, subcutaneous tissues and fascia tend to run longitudinally in an affected limb, axial T1, axial fluid-sensitive and axial T1-FS contrast-enhanced sequences should be included in the imaging protocol.

    Computed tomography studies are usually used to assess patients with pleural effusions, and radiologists should be aware of the significance of different CT findings for the diagnosis of the effusion. The purpose of this study was to evaluate CT findings for etiological diagnosis of pleural effusions. Contrast-enhanced CT of the chest of 211 patients with pleural effusion of definite diagnosis were evaluated. The CT images were evaluated for the presence and extent of pleural effusion, thickening or nodules, extrapleural fat and other changes in the mediastinum or lung. The CT scans were read by two independent observers and correlation between them was evaluated. Comparison of CT findings between benign and malignant effusions, between exudates and transudates, and between empyemas and the other parapneumonic effusions were carried out. Kappa values for most CT findings were >0.85. Loculation, pleural thickening, pleural nodules, and extrapleural fat of increased density were only present in exudative effusions. Multiple pleural nodules and nodular pleural thickening were the only pleural findings limited to malignant pleural effusions. The signs were also more frequently seen in empyemas than in other parapneumonic effusions. Computed tomography findings can help to distinguish between transudates and exudates. Although there is some overlap between benign and malignant pleural effusions, pleural nodules and nodular pleural thickening were present almost exclusively in the latter. Although differences between CT findings of empyemas and the other parapneumonic effusions exist, there is no finding which can definitely differentiate between them. (orig.)

    To determine, through an analysis of radiologic findings, whether the findings of granulosa cell tumors (GCTs) of the ovary are specific. The radiologic findings (ultrasonography, computed tomography, and magnetic resonance imaging) of 16 pathologically proven ovarian GCTs in 15 patients were retrospectively analysed for the site of origin, staging, largest diameter, margin, solid and/or cystic components, degree of enhancement, and associated endometrial hyperplasia, ascites, and local and/or distant metastasis. Unilateral ovarian GCTs were found in 14 patients, and bilateral tumors in one. Of a total of 16 tumors, 13 were of the adult type, and three were juvenile; their largest diameter ranged from 1 to 26(mean, 15.6)cm. Eleven tumors were well-defined, two were cystic, and one small tumor was solid. Of 13 mixed tumors, three had hemorrhagic portions, and five had multilocular cystic portions. Metastases to the uterus, tubes, rectum, lymph nodes, or liver were found in six patients, and associated endometrial hyperplasia in two. Radiologically, ovarian GCTs showed well-defined or encapsulated soft tissue masses with some hemorrhagic, multilocular or focal cystic components, as well as associated endometrial thickening and local or distant metastasis. These and clinical findings may be useful in the diagnosis of ovarian GCTs.

    To evaluate high-resolution CT(HRCT) findings of the miliary tuberculosis and their significance. We retrospectively studied clinical records, HRCT and chest radiographs of 14 patients with miliary tuberculosis. On HRCT, nodules were seen in all 14 cases, 10 of them evenly, and 4 were irregularly distributed. The size of each nodule was less than 1 mm in 7 cases, 1 - 2 mm in 6 cases, and 3 mm or more in 1 case. The ground - glass opacity was accompanied in 8 cases, and fine reticular opacity was also noted in 8 cases. Other associated findings were pleural effusion (n=4), hilar and mediastinal lymphadenopathy (n=3), consolidation of the exudative tuberculosis (n=4). HRCT findings of miliary tuberculosis are diffusely distributed micro nodules of variable size, less than 5 mm in diameter. The ground-glass opacity can be combined

    This study was designed to present characteristic CT and MR findings of calcified spinal meningiomas that correlate with pathological findings and to assess the efficacy of CT for the detection of calcifications within a mass in comparison to MRI. Between 1998 and 2009, 10 out of 11 patients who had pathologically confirmed psammomatous meningiomas showed gross calcifications on CT images and were included in this study. On CT scans of the 10 patients, the distribution pattern, morphology and number of calcifications within masses were evaluated. MRI was performed in seven patients and signal intensities of masses were assessed. The pathological results analyzed semi-quantitatively were compared with the density or the size of calcifications within a mass as seen on a CT scan. Seven of 10 masses were located at the thoracic spine level. Eight masses had intradural locations. The other two masses had extradural locations. Four masses were completely calcified based on standard radiographs and CT. Symptoms duration, the size of the mass and size or number of calcifications within a mass had no correlation. The location, size, and distribution pattern of calcifications within masses were variable. On MR images, signal intensity of calcified tumor varied on all imaging sequences. All the masses enhanced after injection of intravenous contrast material. A calcified meningioma should be first suggested when extradural or intradural masses located in the spine contain calcifications regardless of the size or pattern as depicted on CT, especially in the presence of enhancement as seen on MR images.

    To evaluate the brain MRI findings in patients with neuropsychiatric lupus. In 26 patients (M:F = 2:24 ; aged 9-48 years) in whom the presence of systemic lupus erythematosus was clinically or pathologically proven and in whom neuropsychiatric lupus was also clinically diagnosed, the findings of brain MRI were retrospectively evaluated. MR images were analyzed with regard to the distribution, location, size and number of lesions due to cerebral ischemia or infarction, the presence of cerebral atrophy, and the extent and degree of brain parenchymal and intravascular enhancement. The most common MRI findings were lesions due to cerebral ischemia or infarction occurring in 18 patients (69%), and located within deep periventricular white matter (n=10), subcortical white matter (n=8), the cerebral cortex (n=7), basal ganglia (n=7), or brain stem or cerebellum (n=2). The lesions were single (n=3) or multiple (n=15), and in 17 patients were less than 1cm in diameter in regions other than the cerebral cortex. In six of these patients, lesions of 1-4cm in diameter in this region were combined, and one occurred in the cerebral cortex only. Cerebral atrophy was seen in 16 patients (62%), in ten of whom there was no past history of treatment with steroids for more than six months. In 15 patients (58%), contrast-enhanced MR image revealed diffuse enhancement of the basal ganglia or intravascular enhancement. In no case were MRI findings normal. The primary mainfestations of neuropsychiatric lupus are multifocal ischemia or infarctions in the cerebral cortex, and subcortical and deep white matter, and the cerebral atrophy. Contrast-enhanced MR images also demonstrated diffuse enhancement of the basal ganglia and intravascular enhancement, both thought to be related to the congestion due to the stagnation of cerebral blood flow.

    To evaluate MR characteristics of acute disseminated encephalomyelitis (ADEM) in children, which was confirmed by clinical findings. The subjects were six patients, who were diagnosed by clinical findings. One subject had recurrence one year after clinical improvement leading to one additional care with the total of seven. The modes of viral infections were as follows; four cases of non-specific upper respiratory tract infection, one of E-B virus, one f Japanese-B-encephalitis vaccination, and one of upper respiratory infection in Bruton's disease. The Gd-DTPA enhanced scan was performed in all cases. MR findings were evaluated in anatomic location of the lesions, presence or absence of contrast enhancement, and the temporal changes were also evaluated on follow-up MRI. There were multifocal high signal intensity lesions on T2WI in all cases. The location of lesions were basal ganglia in five, thalamus and brain stem in four, and cerebral gray and white matter and cerebellar white matter in three. Bilaterality was 77%. There were contrast enhancement in two of three cerebral cortical lesions and one of three white matter lesions. The size of lesions decreased on the first follow-up MRI which were done after 1 month in 4 cases, but new lesions were developed in two cases. On the second follow-up MRI which were done 2 months after, all lesions were decreased in size and there was no newly developed lesion. However, in one case who had recurrent similar symptom after 1 year, several new lesions developed on follow-up MRI, and it was comidened as a recurrence. The characteristic MR findings of ADEM were multifocal bilateral white and gray matter lesions which were high signal intensities on T2WI. The majority of lesions improved on follow-up MRI, but occasionally showed multiphasic pattern

    To review the sonographic findings of various diseases showing architectural distortion depicted under mammography. We collected and reviewed architectural distortions observed under mammography at our health institution between 1 March 2004, and 28 February 2007. We collected 23 cases of sonographically-detected mammographic architectural distortions that confirmed lesions after surgical resection. The sonographic findings of mammographic architectural distortion were analyzed by use of the BI-RADS lexicon for shape, margin, lesion boundary, echo pattern, posterior acoustic feature and orientation. There were variable diseases that showed architectural distortion depicted under mammography. Fibrocystic disease was the most common presentation (n = 6), followed by adenosis (n = 2), stromal fibrosis (n = 2), radial scar (n = 3), usual ductal hyperplasia (n = 1), atypical ductal hyperplasia (n = 1) and mild fibrosis with microcalcification (n = 1). Malignant lesions such as ductal carcinoma in situ (DCIS) (n = 2), lobular carcinoma in situ (LCIS) (n = 2), invasive ductal carcinoma (n = 2) and invasive lobular carcinoma (n = 1) were observed. As observed by sonography, shape was divided as irregular (n = 22) and round (n = 1). Margin was divided as circumscribed (n = 1), indistinct (n = 7), angular (n = 1), microlobulated (n = 1) and sipculated (n = 13). Lesion boundary was divided as abrupt interface (n = 11) and echogenic halo (n = 12). Echo pattern was divided as hypoechoic (n = 20), anechoic (n = 1), hyperechoic (n = 1) and isoechoic (n = 1). Posterior acoustic feature was divided as posterior acoustic feature (n = 7), posterior acoustic shadow (n = 15) and complex posterior acoustic feature (n = 1). Orientation was divided as parallel (n = 12) and not parallel (n = 11). There were no differential sonographic findings between benign and malignant lesions. This study presented various sonographic findings of mammographic architectural distortion and that it is

    The purpose of this study was to evaluate the MR findings and useful sequences in Polymyositis/ Dermatomyositis, and to correlate MR findings with disease activity. Materials and Methods: The study included nine clinically proven cases of Polymyositis/Dermatomyositis, eight involving the thigh and one, the shoulder (2 cases, 1 follow-up). The contrast between affected and normal muscles and difference in signal intensity ratio in the muscle groups were retrospectively evaluated on Gd-enhanced T1WI and T2WI. We also evaluated the magnitude of involvement of muscle groups, fatty replacement of muscle and change of subcutaneous fat layer, and correlated signal intensity ratio with serum level of muscle enzymes. Differences in signal intensity ratio and the frequency of chemical shift artifact were evaluated on T2WI as active and inactive groups classified according to clinical findings, and the chemical shift artifact was correlated with the finding of Gd-enhanced T1WI. Except in the case of one shoulder, statistical analysis was assessed by the Anova test and-test. Results: On Gd-enhanced T1WI and T2WI contrast was 0.54 and 0.82, respectively and p value was 0.02. With regard to difference in signal intensity ratios of muscle groups, as seen on Gd-enhanced T1WI and T2WI, p valves were 0.07 and < 0.01, respectively. Muscle involvement was thus clearly visualized on T2WI. The order of frequency of involved muscle groups was vastus muscles, gluteus maximus, sartorius muscles, adductor muscles, gracilis muscle, and hamstring muscles. Fatty replacement and subcutaneous fatty change were visualized in five cases and one, respectively. The correlation coefficient between the signal intensity seen on T2WI and muscle enzymes was 0.59 (CPK) and 0.52 (LDH). The chemical-shift artifact was detected in both clinical groups (four active two inactive) and corresponded to one case of muscle involvement and five of perimuscular edema, as seen on Gd-enhanced T1WI. Conclusion: T2WI is

    The results of a prospective study to compare the plain radiographic and lumbar myelographic findings with the surgical findings in 70 cases of suspected thoracolumbar disc protrusion in the dog are reported. The aim was to assess the relative accuracy of disc lesion localisation using plain and contrast radiography. From the plain radiographs, the affected disc space was correctly identified in 40 cases (57.1 per cent), and incorrectly identified in seven. More than one site was identified in 11; in eight of these dogs, the affected disc space was strongly suspected. It was not possible to identify an affected disc in 12 cases. The site of disc protrusion was accurately identified by myelography in 60 dogs (85.7 per cent). In four dogs, myelography was helpful in identifying an adjacent disc and, in a further two, cord swelling was found at surgery. In one dog, neither disc material nor cord swelling was identified. Three myelograms were non-diagnostic

    Expert finding problem in bibliographic networks has received increased interest in recent years. This problem concerns finding relevant researchers for a given topic. Motivated by the observation that rarely do all coauthors contribute to a paper equally, in this paper, we propose two discriminative methods for realizing leading authors contributing in a scientific publication. Specifically, we cast the problem of expert finding in a bibliographic network to find leading experts in a research group, which is easier to solve. We recognize three feature groups that can discriminate relevant experts from other authors of a document. Experimental results on a real dataset, and a synthetic one that is gathered from a Microsoft academic search engine, show that the proposed model significantly improves the performance of expert finding in terms of all common information retrieval evaluation metrics.

    The complexity of neurophysiology data has increased tremendously over the last years, especially due to the widespread availability of multi-channel recording techniques. With adequate computing power the current limit for computational neuroscience is the effort and time it takes for scientists to translate their ideas into working code. Advanced analysis methods are complex and often lack reproducibility on the basis of published descriptions. To overcome this limitation we develop FIND (Finding Information in Neural Data) as a platform-independent, open source framework for the analysis of neuronal activity data based on Matlab (Mathworks). Here, we outline the structure of the FIND framework and describe its functionality, our measures of quality control, and the policies for developers and users. Within FIND we have developed a unified data import from various proprietary formats, simplifying standardized interfacing with tools for analysis and simulation. The toolbox FIND covers a steadily increasing number of tools. These analysis tools address various types of neural activity data, including discrete series of spike events, continuous time series and imaging data. Additionally, the toolbox provides solutions for the simulation of parallel stochastic point processes to model multi-channel spiking activity. We illustrate two examples of complex analyses with FIND tools: First, we present a time-resolved characterization of the spiking irregularity in an in vivo extracellular recording from a mushroom-body extrinsic neuron in the honeybee during odor stimulation. Second, we describe layer specific input dynamics in the rat primary visual cortex in vivo in response to visual flash stimulation on the basis of multi-channel spiking activity.

    Cysticercosis is a parasitic disease in which man serves as the intermediate host of Taenia Solium, the pork tapeworm. The computed tomographic findings of 25 cases of intracerebral cysticercosis proven by pathologic and/or clinical findings during past 2 years were analysed. The results were as follows; 1. The sex was 19 males and 6 females, and 56 percent of the patients were seen in fourth and fifth decades. The most common symptom was epilepsy (72%). 2. The C. T. findings in precontrast study were varied; such as ill defined low density (48%), cystic low density (20%), dilated ventricles (20%), ill defined low density with isodense nodule (18%), cystic low density with isodense mural nodule (12%) and calcification (8%). 3. The areas of involvement were 20 cases (80%) of parenchymal form, 3 cases (12%) of ventricular form and 2 cases (8%) of mixed form. 4. The contrast-enhanced 13 cases were 5 nodular, 5 ring or rim-like and 3 mixed type enhancements, while 12 cases were not enhanced. 5. C.T. scan demonstrated more precise location and extents of cerebral cysticercosis, especially in parenchymal form. It was considered to be important in determination of surgical feasibility and its approach.
