Abstract Blackberry is a species which has high potential to grow in an organic production system. However, there is scarce information on the behavior of cultivars and selections of this species conducted in an ecologically based system, a fact that makes it difficult to recommend cultivars for this production system. This study aimed to evaluate and characterize the phenology and productive aspects of six blackberry genotypes grown in an organic system, in Pelotas, Rio Grande do Sul (RS) state, Brazil. Evaluation of the following variables was carried out in the three first production cycles (2015-2016, 2016-2017 and 2017-2018): phenology, number of fruits.plˉ¹, mean fruit yield.plˉ¹, yield (kg.haˉ¹), mean fruit mass (g) and soluble solid content (° Brix). Regarding phenology, genotype Black 112 was later than the others whereas Black 178 was the most precocious one. In the last year under evaluation, genotypes yielded around 10 ton.haˉ¹, except Black 128 selection, which yielded approximately 6,767 ton.haˉ¹. Genotypes Black 178, Black 112 and Black 145 and both cultivars BRS Xingu and Tupy exhibited potential to grow in an organic production system.

Resumo Objetivo: Avaliar a prevalência dos distúrbios hipertensivos, resultados perinatais (recém-nascidos pré-termo, recém-nascidos de baixo peso, índice de Apgar < 7 no 5° minuto e óbitos fetais) e as taxas de cesarianas nas gestantes internadas para assistência ao parto na Maternidade Hilda Brandão da Santa Casa de Belo Horizonte, Belo Horizonte, MG, Brasil, no período de 1° de março de 2008 a 28 de fevereiro de 2018. Métodos: Foi realizado um estudo analítico, observacional, longitudinal. Os grupos selecionados para comparação foram gestantes com e sem distúrbios hipertensivos. Do total de 36.724 gestantes, 4.464 foram diagnosticadas com distúrbios hipertensivos e 32.260 não apresentavam distúrbios hipertensivos. Resultados: A prevalência dos distúrbios hipertensivos foi de 12,16%; Os resultados perinatais e as taxas de cesarianas entre os 2 grupos de gestantes com e sem distúrbios hipertensivos foram: recém-nascidos pré-termo (21,70% versus 9,66%; odds ratio [OR] 2,59; intervalo de confiança [IC] 95%, 2,40-2,80; p < 0,001); recém-nascidos de baixo peso (24,48% versus 10,56%; OR 2,75; IC 95%, 2,55-2,96; p < 0,001); índice de Apgar < 7 no 5° minuto (1,40% versus 1,10%; OR 1,27; IC 95%, 0,97-1,67; p = 0,084); fetos mortos diagnosticados previamente ao parto (1,90% versus 0,91%; OR 2,12; IC 95%, 1,67-2,70; p < 0,001); taxas de cesarianas (60,22% versus 31,21%; OR 3,34; IC 95%, 3,14-3,55; p < 0,001). Conclusão: Os distúrbios hipertensivos estão associados a maiores taxas de cesarianas, ao maior risco de recém-nascidos pré-termo, recém-nascidos de baixo peso e a um maior risco de óbitos fetais.

Abstract Objective: To evaluate the prevalence of hypertensive disorders, perinatal outcomes (preterm infants, low birthweight infants and Apgar score < 7 at the 5th minute and fetal deaths) and the cesarean rates in pregnant women hospitalized for delivery at the Maternidade Hilda Brandão da Santa Casa de Belo Horizonte, Belo Horizonte, state of Minas Gerais, Brazil, from March 1, 2008 to February 28, 2018. Methods: A case-control study was performed, and the groups selected for comparison were those of pregnant women with and without hypertensive disorders. Out of the 36,724 women, 4,464 were diagnosed with hypertensive disorders and 32,260 did not present hypertensive disorders Results: The prevalence of hypertensive disorders was 12.16%; the perinatal outcomes and cesarean rates between the 2 groups with and without hypertensive disorders were: preterm infants (21.70% versus 9.66%, odds ratio [OR] 2.59, 95% confidence interval [CI], 2.40-2.80, p < 0.001); low birthweight infants (24.48% versus 10.56%; OR 2.75; 95% CI, 2.55-2.96; p < 0.001); Apgar score < 7 at the 5th minute (1.40% versus 1.10%; OR 1.27; 95% CI, 0.97-1.67; p = 0.84); dead fetuses diagnosed prior to delivery (1.90% versus 0.91%; OR 2.12; 95% CI, 1.67-2.70; p < 0.001); cesarean rates (60.22% versus 31.21%; OR 3.34; 95% CI, 3.14-3.55; p < 0.001). Conclusion: Hypertensive disorders are associated with higher rates of cesarean deliveries and higher risk of preterm infants, low birthweight infants and a higher risk of fetal deaths.

Resumo Objetivo: Avaliar a associação entre anemia e síndrome de fragilidade em idosos da comunidade. Método: Trata-se de uma revisão sistemática da literatura nos idiomas inglês, espanhol e português, nas bases de dados MEDLINE e LILACS no período de 2007 a 2016. A inclusão dos artigos foi guiada pelo Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Resultados: Essa revisão identificou 193 artigos e após eliminação dos artigos duplicados e dos critérios de exclusão, foram incluídos sete artigos. Três artigos utilizaram critérios padronizados para definição de fragilidade e quatro estudos avaliaram a capacidade funcional como sinônimo de síndrome de fragilidade. Conclusão: A anemia mostrou-se relacionada à piora da capacidade funcional e à presença da síndrome de fragilidade em idosos da comunidade. Entretanto, o risco de viés dos estudos foi alto durante a seleção dos critérios e dos instrumentos utilizados para avaliação e definição da fragilidade.

Abstract Objective: To evaluate the association between anemia and the onset of the frailty syndrome amongst the elderly living in the community. Method: A systematic literature review of articles from the MEDLINE and LILACS databases published in English, Spanish and Portuguese over the last ten years was carried out. Articles were included in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: The search identified 193 studies. After deleting duplicated articles and applying the exclusion criteria only seven articles remained. Three articles used standardized criteria to define frailty, whereas four evaluated functional capacity as a synonym for the frailty syndrome. Conclusion: Anemia was related to a worsening of functional capacity and to the presence of the frailty syndrome in elderly persons living in the community. However, the risk of bias in the studies was high in relation to the selection of the criteria and instruments used to assess and define frailty.

Resumo Introdução: O envelhecimento está relacionado a perda de massa muscular, imunossenescência e o aumento da produção de mediadores inflamatórios, cujos níveis elevados são preditores do declínio da capacidade funcional na população idosa. Objetivo: Avaliar a associação entre mediadores inflamatórios, interleucina-6 (IL-6) e proteína C-reativa (PCR) e capacidade funcional no idoso. Métodos: Estudo transversal com 308 idosos da comunidade. O estudo foi aprovado pelo Comitê de Ética e Pesquisa, 067/2010. A força de preensão manual (FPM) foi avaliada através do dinamômetro de JAMAR® e a capacidade funcional pelo teste Timed Up and Go. Foi realizado um exame de sangue e analisados os níveis séricos de proteína C-reativa e interleucina-6. Utilizou-se o coeficiente de Spearman para verificar a correlação entre as variáveis e o teste de Mann-Whitney para comparação entre os grupos. O nível de significância utilizado foi de 0,05. Resultados: Não houve correlação significativa entre a FPM e o Timed Up and Go e os mediadores inflamatórios (PCR e IL-6). Porém, ao controlar as variáveis como idade, gênero e índice de massa muscular encontrou-se uma associação significativa e inversa (p = 0,023) entre a FPM e os níveis de PCR. Conclusão: Idosos com baixos índices de proteína C-reativa apresentaram melhor desempenho no teste de força muscular manual. É destacável a importância da investigação dos desfechos adversos que podem ser influenciados pela citocinas inflamatórias na capacidade funcional dos idosos durante o envelhecimento.

Abstract Introduction: Aging is associated with loss of muscle mass, immunosenescence and increased production of inflammatory mediators, high levels being predictors of a decline in functional capacity in the elderly. Objective: To assess the association between inflammatory mediators, interleukin 6 (IL-6) and C-reactive protein (CRP) and functional capacity in the elderly. Methods: Cross-sectional study with 308 community-dwelling elderly. The study was approved by the Research Ethics Committee, under protocol number 067/2010. Grip strength (GS) was measured using a JAMAR® dynamometer and functional capacity by the Timed Up and Go (TUG) test. Blood tests were performed and serum levels of C-reactive protein and interleukin 6 assessed. Spearman’s coefficient was applied to analyze the correlation between variables and the Mann-Whitney for intergroup comparison. Significance was set at 0.05. Results: There was no significant correlation between GS, the TUG and inflammatory mediators (CRP and IL-6). However, by adjusting for variables such as age, sex and muscle mass, a significant and inverse correlation (p = 0.023) was observed between GS and CPR. Conclusion: Elderly subjects with low C-reactive protein levels performed better in the grip strength test. It is important to investigate the adverse effects on functional capacity that can be influenced by inflammatory cytokines in the elderly during aging.

Resumen Introducción: El envejecimiento se relaciona con una pérdida de masa muscular, inmunosenescencia, tanto el aumento de la producción de mediadores inflamatorios, cuyos niveles elevados son predictores de disminución de la capacidad funcional en la población de edad avanzada. Objetivo: Investigar la asociación entre mediadores inflamatorios, interleucina-6 (IL-6) y proteína C reactiva (CRP) y capacidad funcional en los ancianos. Métodos: Estudio transversal con 308 ancianos de la comunidad. El estudio fue aprobado por el Comité de Ética e Investigación, 067/2010. La fuerza de la empuñadura (GS) se evaluó utilizando el dinamómetro JAMAR® y la capacidad funcional mediante la prueba Timed Up and Go. Se realizó un análisis de sangre y se analizaron los niveles séricos de proteína C reactiva e interleucina-6. El coeficiente de Spearman se utilizó para verificar la correlación entre las variables y la prueba de Mann-Whitney para la comparación entre los grupos. El nivel de significancia fue 0,05. Resultados: No hubo correlación significativa entre GS y Timed Up and Go y mediadores inflamatorios (CRP e IL-6). Sin embargo, cuando se controlaron variables como la edad, el sexo y el índice de masa muscular, hubo una asociación significativa (p = 0,023) entre los niveles de GS y CRP, es decir, los individuos que obtuvieron buenos resultados en el GS obtuvieron niveles más bajos de PCR circulante. Conclusión: Los pacientes ancianos con bajos niveles de proteína C reactiva, presentaron mejor desempeño en la prueba de fuerza muscular manual. Es importante investigar los efectos adversos que pueden estar influenciados por las citosinas inflamatorias sobre la capacidad funcional de los ancianos durante el envejecimiento.

Abstract INTRODUCTION: The Kato-Katz technique is the standard diagnostic test for Schistosoma mansoni infection in rural areas. However, the utility of this method is severely limited by the day-to-day variability in host egg excretion in the stool. In high-transmission areas, the point-of-care circulating cathodic antigen (POC-CCA) urine assay has proven to be a reliable test. However, investigations of the reliability of the POC-CCA assay in low-transmission regions are under way. This study aimed to evaluate the sensitivity and specificity of the POC-CCA assay and the morbidity of schistosomiasis in a low-endemic area in Brazil. METHODS: Pains City is a low-transmission zone for schistosomiasis. A total of 300 subjects aged 7-76 years were randomly selected for the POC-CCA cassette test. For S. mansoni diagnosis, three stool samples on six slides were compared with one urine sample for each subject. The sensitivity and specificity in the absence of a gold standard were calculated using latent class analysis. Clinical examinations and abdominal ultrasounds were performed in 181 volunteers to evaluate morbidity associated with schistosomiasis. RESULTS: The sensitivity and specificity of the Kato-Katz technique were 25.6% and 94.6%, respectively. By contrast, the sensitivity and specificity of the POC-CCA assay were 68.1% and 72.8%, respectively. Hepatosplenic schistosomiasis was diagnosed in two patients (1.1%). CONCLUSIONS: Overall, the POC-CCA urine assay proved to be a useful test for diagnosing S. mansoni in a low-endemic area in Brazil. Severe clinical forms of schistosomiasis can be present even in such low-endemic areas.

Resumo Introdução: Trombocitopenia é um achado comum em pacientes que residem em áreas com alta endemicidade de esquistossomose mansônica. Recentemente, diferentes graus de esteatose hepática também têm sido associados a níveis baixos de plaquetas em todo o mundo. Investigamos a associação de níveis séricos de plaquetas com a forma grave da esquistossomose e com esteatose hepática em área de baixa prevalência de esquistossomose no Brasil. Método: Pains, cidade localizada no estado de Minas Gerais/Brasil, tem população de 8.307 habitantes e prevalência de esquistossomose de 8%. Em quatro microáreas dessa região, 1.045 habitantes foram avaliados para o estudo. Amostra de sangue foi coletada para realização do hemograma. Oitenta e sete (87) pessoas com níveis baixos de plaquetas formaram o grupo 1 (8,3%), e 94 voluntários com hemograma normal foram randomizados para compor o grupo 2 (8,9%). Todos os participantes dos grupos 1 e 2 foram submetidos a exame clínico e ultrassonografia (US) abdominal. Esteatose hepática foi caracterizada como presente ou ausente pela ultrassonografia (US) abdominal. Baços com mais de 12 cm de comprimento à US foram considerados aumentados. Os dados coletados foram analisados pelo programa de estatística SPSS 19.0. Resultados: Vinte e dois (22) indivíduos do grupo 1 (25,3%) e 11 do grupo 2 apresentaram esteatose hepática (11,7%) (p=0,02). Esquistossomose hepatoesplênica foi diagnosticada em dois pacientes (p>0,05). Conclusão: Trombocitopenia não foi um bom marcador de esquistossomose mansônica hepatoesplênica em área de baixa prevalência da esquistossomose no Brasil. Esteatose hepática foi associada com trombocitopenia no presente estudo.

Summary Introduction: Thrombocytopenia is commonly found in patients living in highly endemic areas for Schistosoma mansoni. Recently, different degrees of liver steatosis have also been associated with low platelet counts worldwide. We investigated the association of platelet counts with hepatosplenic schistosomiasis and with liver steatosis in an area of low prevalence of schistosomiasis in Brazil. Method: Pains, a city in the state of Minas Gerais, Brazil, had a population of 8,307 inhabitants and a schistosomiasis prevalence of 8%. Four micro-areas comprising 1,045 inhabitants were selected for this study. Blood sample was collected and a complete blood count (CBC) was performed. Eighty-seven (87) patients had low platelet counts (group 1 - 8.3%) and 94 volunteers presenting normal CBC were randomized (group 2 - 8.9%). They underwent clinical and ultrasound examinations. Liver steatosis was determined as either present or absent using abdominal ultrasound. A spleen > 12 cm in length, measured by ultrasound (US), was considered to be increased. Data collected were analyzed using SPSS software version 19.0. Results: Twenty-two patients (22/25.3%) in group 1 had liver steatosis compared with 11 volunteers (11.7%) in group 2 (p=0.02). Hepatosplenic schistosomiasis was diagnosed in two patients (p>0.05). Conclusion: Thrombocytopenia was not a good marker of hepatosplenic schistosomiasis mansoni in a low prevalence area in Brazil. Liver steatosis was associated with thrombocytopenia in our study.

Introduction Human neuroschistosomiasis has been reported in the literature, but the possibility of modeling neuroschistosomiasis in mice is controversial. Methods In two research laboratories in Brazil that maintain the Schistosoma mansoni life cycle in rodents, two mice developed signs of brain disease (hemiplegia and spinning), and both were autopsied. Results S. mansoni eggs, both with and without granuloma formation, were observed in the brain and meninges of both mice by optical microscopy. Conclusions This is the first description of eggs in the brains of symptomatic mice that were experimentally infected with S. mansoni. An investigation of experimental neuroschistosomiasis is now feasible.

Introduction This study aimed to evaluate whether a low platelet count is a good surrogate marker of hepatosplenic schistosomiasis (HSS) in a rural area of Brazil. A small district in southeastern Brazil, with a population of 1,543 individuals and a 23% prevalence of schistosomiasis, was selected for this investigation. Methods In July 2012, 384 volunteers were subjected to clinical, ultrasonography (US), and laboratory examinations, including stool sample analysis. The HSS patients were classified into four groups: Group 1 consisted of patients with a spleen >13cm and liver fibrosis; Group 2 consisted of patients with a palpable spleen and spleen>13cm measured by US; Group 3 consisted of patients with a spleen >13cm measured by US; and Group 4 consisted of patients with a palpable spleen. Results Eight patients were in Group 1 (2.1%), twenty-one were in Group 2 (5.5%), eight were in Group 3 (2.1%), and eighteen were in Group 4 (4.7%). A significant difference in the mean platelet counts was observed between the patients with and without HSS (p<0.01). Based on the receiver operating characteristic (ROC) curve (platelet count <143,000/mm3), the sensitivity was greater than 92% in all groups, and the specificity varied from 44.4% to 75%. Conclusions We concluded that in endemic areas, thrombocytopenia demonstrates good sensitivity for detecting HSS and may be used as a screening tool to identify patients with HSS.

Abstract: En | Text: En | PDF: En

Leprosy is an infectious and contagious spectral disease accompanied by a series of immunological events triggered by the host response to the aetiologic agent, Mycobacterium leprae . The induction and maintenance of the immune/inflammatory response in leprosy are linked to multiple cell interactions and soluble factors, primarily through the action of cytokines. The purpose of the present study was to evaluate the serum levels of tumour necrosis factor (TNF)-α and its soluble receptors (sTNF-R1 and sTNF-R2) in leprosy patients at different stages of multidrug treatment (MDT) in comparison with non-infected individuals and to determine their role as putative biomarkers of the severity of leprosy or the treatment response. ELISA was used to measure the levels of these molecules in 30 healthy controls and 37 leprosy patients at the time of diagnosis and during and after MDT. Our results showed increases in the serum levels of TNF-α and sTNF-R2 in infected individuals in comparison with controls. The levels of TNF-α, but not sTNF-R2, decreased with treatment. The current results corroborate previous reports of elevated serum levels of TNF-α in leprosy and suggest a role for sTNF-R2 in the control of this cytokine during MDT.

O presente estudo avaliou a associação entre anemia e a capacidade física funcional em idosos hospitalizados. Estudo transversal, com amostra de 709 participantes com idades ≥ 60 anos, internados no Hospital Madre Teresa, em Belo Horizonte, Minas Gerais, Brasil. Foram utilizados os testes de Mann-Whitney ou "t" e qui-quadrado ou teste exato de Fisher para as variáveis quantitativas e categóricas, respectivamente, e um modelo hierárquico de regressão logística foi usado para identificar as variáveis preditoras associadas. A presença de anemia foi encontrada em 30% dos participantes e associada a uma diminuição significativa da funcionalidade em ambos os índices utilizados - AVD (atividades da vida diária) e AIVD (atividades instrumentais da vida diária). A idade avançada também foi independentemente associada com anemia. Os resultados deste estudo demonstraram uma forte associação entre a redução da capacidade funcional e a presença de anemia. Investigações adicionais são necessárias para avaliar o impacto do tratamento da anemia na melhora da funcionalidade e independência em pessoas idosas.

This study evaluated the association between anemia and physical functional capacity in a cross-sectional population-based sample of 709 hospitalized elderly patients aged 60 years and over admitted to the Madre Teresa Hospital, Belo Horizonte, State of Minas Gerais, Brazil. The Mann-Whitney or "t" test, and chi-square or Fisher exact test were used for quantitative and categorical variables, respectively, and hierarchical binary logistic regression was used to identify significant predictors. The presence of anemia was found in 30% of participants and was significantly associated with decreased functionality according to the two measures which were used - ADL (activities of daily living) and IADL (instrumental activities of daily living). Anemia was also independently associated with older age. The results of this study demonstrate a strong association between the presence of anemia and lower levels of functional capacity. Further investigations are needed to assess the impact of anemia treatment on the functionality and independence of older people.

Se trató de un estudio transversal con una muestra de 709 participantes con edad ≥ 60 años, ingresados en el hospital Madre Teresa, Belo Horizonte, Minas Gerais, Brasil. Se aplicó el Mann-Whitney o "t" y chi-cuadrado o la prueba exacta de Fisher para las variables cuantitativas y categóricas, respectivamente, así como un modelo jerárquico binario de regresión logística para identificar predictores significativos. La presencia de anemia se encontró en un 30% de los participantes y se asoció con una disminución significativa de la funcionalidad en ambos índices utilizados - AVD (actividades de la vida diaria) y de AIVD (actividades instrumentales de la vida diaria). La edad avanzada también se asocia de forma independiente con la anemia. Los resultados de este estudio demostraron una fuerte asociación entre una menor capacidad funcional y la presencia de anemia. Se necesitan más investigaciones para evaluar los efectos del tratamiento de la anemia en la mejora de la funcionalidad y la independencia de los ancianos.

IntroductionThe diagnosis of schistosomiasis mansoni on early stages of infection is important to prevent late morbidity. A simple, cheap, sensitive and specific assay for routine diagnosis of schistosome infection based on the detection of specific IgG for schistosomula tegument antigens (ELISA-SmTeg) was developed by our group.MethodsWe describe here an acute outbreak involving a travel group of 80 individuals from a non-endemic area of the State of Minas Gerais, Brazil. These individuals were in contact with a freshwater pool where Biomphalaria glabrata was found. Results obtained from our new methodology were compared to IgG antibody titers against soluble worm antigenic preparation (SWAP) by ELISA and, also to parasitological examination, nuclear magnetic resonance and clinical findings.ResultsELISA-SmTeg was capable of detecting 64 positive cases among the 80 individuals participating at the survey with a positivity ratio of 80% and a higher sensitivity than ELISA-SWAP that was only sensitive for 56% of positive cases. Besides, a significant correlation was found for the severity of the infection and the specific IgG titers against SmTeg.ConclusionsOur data showed that ELISA-SmTeg might serve as the initial diagnostic tool for acute stages of the infection in community-based helminth control programs or for the surveillance of individuals from non-endemic areas.

INTRODUÇÃO: Não existem estudos que correlacionam os achados da ressonância magnética (RM) aos da ultrassonografia (US) em pacientes com esquistossomose mansônica. O objetivodeste estudo foi descrever os achados da imagem por RM em pacientes com doença hepática esquistossomótica identificada por US. MÉTODOS: Selecionaram-se 54 pacientes com idade média de 41,6±13,5 anos, provenientes de área endêmica para a esquistossomose mansônica. Todos apresentavam US indicativa de fibrose hepática esquistossomótica, e foram avaliados com imagens por RM, realizadas com uma unidade magnética supercondutora de 1,5-T(Sigma). RESULTADOS: Quarenta e sete (87%) entre 54 pacientes com sinais ultrassonográficosde fibrose periportal esquistossomótica tiveram este diagnóstico confirmado pela RM. Nos sete(13%) casos discordantes, a RM revelou tecido adiposo preenchendo o espaço periportal hilaronde a US indicava espessamento isolado da parede da veia porta em seu ponto de entrada no fígado. Este achado foi nomeado sinal do hilo gorduroso. Um dos 47 pacientes com evidência de fibrose periportal RM era colecistectomizado. Trinta e quatro (76,1%) dos 46 pacientes restantes apresentavam expansão da fossa da vesícula, que se encontrava preenchida portecido adiposo. Nos outros sete, a RM revelou sinais de fibrose pericolecística. CONCLUSÕES: Os espessamentos ecogênicos central da parede da veia porta, e da parede da vesícula biliar, até o momento, atribuídos à fibrose, foram frequentemente identificados como tecido adiposopela RM. Entretanto, o espessamento da parede da vesícula identificado pela US (expansão da fossa da vesícula na RM) é provavelmente secundário a alterações morfológicas hepáticas na esquistossomose, e representa comprometimento grave do fígado.

INTRODUCTION: There is no study relating magnetic resonance imaging (MRI) to ultrasound (US) findings in patients with Schistosomiasis mansoni. Our aim was to describe MRI findings inpatients with schistosomal liver disease identified by US. METHODS: Fifty-four patients (mean age 41.6±13.5years) from an area endemic for Schistosomiasis mansoni were selected for this study.All had US indicating liver schistosomal fibrosis and were evaluated with MRI performed witha 1.5-T superconducting magnet unit (Sigma). RESULTS: Forty-seven (87%) of the 54 patientsshowing signs of periportal fibrosis identified through US investigation had confirmed diagnosesby MRI. In the seven discordant cases (13%), MRI revealed fat tissue filling in the hilar periportalspace where US indicated isolated thickening around the main portal vein at its point of entryto the liver. We named this the fatty hilum sign. One of the 47 patients with MRI evidence ofperiportal fibrosis had had his gallbladder removed previously. Thirty-five (76.1%) of the other46 patients had an expanded gallbladder fossa filled with fat tissue, whereas MRI of the remainingeleven showed pericholecystic signs of fibrosis. CONCLUSIONS: Echogenic thickening of thegallbladder wall and of the main portal vein wall heretofore attributed to fibrosis were frequentlyidentified as fat tissue in MRI. However, the gallbladder wall thickening shown in US (expandedgallbladder fossa in MRI) is probably secondary to combined hepatic morphologic changes inschistosomiasis, representing severe liver involvement.
