Desde la pérdida de la fuerza hasta el compromiso sistémico: serie de casos del síndrome POEMS / From limb weakness to a systemic involvement: Poems syndrome case two report and review of the literature

El síndrome POEMS es un trastorno paraneoplásico raro y poco frecuente, que se presenta principalmente en la sexta década de la vida, caracterizado por el compromiso multisistémico con predominio de neuropatía desmielinizante. Abarca diversas y heterogéneas manifestaciones clínicas y su diagnóstico requiere un alto índice de sospecha. Se presentan dos casos de pacientes que consultaron por cuadros poco frecuentes en los que la pérdida de la fuerza orientó al acercamiento de una afectación multisistémica que concluyó con el diagnóstico de esta enfermedad(AU)

POEMS syndrome is a rare and infrequent paraneoplastic syndrome, which occurs mainly in the sixth decade of life, characterized by multisystem involvement with a predominance of demyelinating neuropathy, which encompasses diverse and heterogeneous clinical manifestations and whose diagnosis requires a high index of suspicion. We present two cases of patients who consulted due to unusual symptoms and whose loss of strength led to an approach due to multisystem involvement that concluded with the diagnosis of this disease(AU)

Clinical and histopathological characteristics of diabetic patients with nephrotic proteinuria. A case series / Características clínicas e histopatológicas de pacientes diabéticos con proteinuria nefrótica. Una serie de casos

Abstract Objective: to describe the clinical and histopathological characteristics of diabetic patients with nephrotic-range proteinuria. Materials and methods: the kidney biopsies of diabetic patients with nephrotic proteinuria were reviewed. Descriptive analyses were performed along with a comparison of three groups according to the histopathological findings. Results: the medical charts of 19 patients from 2018 through 2020 were collected, most of whom (94.7%) were diagnosed with type 2 diabetes mellitus (DM), with an average age of 58 years, and an average duration of DM of 9.9 years (SD: ±7.3). The findings from biopsies performed throughout the years prior to data collection showed that 26.3% had diabetic nephropathy as the only finding, 31.6% had a nephropathy other than diabetic nephropathy, and 42.1% had findings of both diabetic and nondiabetic nephropathy. A comparison of the groups showed a significant difference in the duration of DM, which was greater in patients with diabetic nephropathy (16.4 vs. 5 vs. 9.5 years, respectively, p: 0.024). Conclusions: we present a case series of diabetic patients with nephrotic-range proteinuria in Colombia, showing that kidney biopsy lesions other than diabetic nephropathy may be a cause of proteinuria. We found that patients with a report of DN alone had a much longer duration of diabetes. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2231).

Resumen Objetivo: describir las características clínicas e histopatológicas de pacientes diabéticos con proteinuria en rango nefrótico. Material y métodos: se revisaron biopsias renales de pacientes diabéticos con proteinuria ne frótica, se realizaron análisis descriptivos y comparación entre tres grupos de acuerdo con hallazgos histopatológicos. Resultados: se recolectaron historias de 19 pacientes, entre los años 2018 y 2020, la mayoría (94.7%) con diagnóstico de diabetes mellitus (DM) tipo 2, edad promedio de 58 años, con un tiempo de evolución de la DM en promedio de 9.9 años (DE: ±7.3). En los hallazgos de la biopsia, practica das a lo largo de años anteriores a la recolección, se encontró que 26.3% tenían nefropatía diabética como único hallazgo, el 31.6% otra nefropatía diferente a la diabética y 42.1% hallazgos tanto de nefropatía diabética como no diabética. Al comparar los grupos se encontró diferencia significativa en el tiempo de evolución de la DM, siendo mayor en pacientes con nefropatía diabética (16.4 vs 5 vs 9.5 años respectivamente, p: 0.024). Conclusiones: se presenta una serie de casos de pacientes diabéticos con proteinuria en rango nefrótico en Colombia, mostrando que existen lesiones diferentes a la nefropatía diabética en la biopsia renal como posible causa de la proteinuria. Se encontró que los pacientes en quienes se reportó ND únicamente, tenían un tiempo de evolución de la diabetes mucho mayor. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2231).

Swallowing in behavioral variant frontotemporal dementia / Deglutição na variante comportamental da demência frontotemporal

ABSTRACT Background: Swallowing and feeding problems may occur with the progression of behavioral variant frontotemporal dementia (bvFTD) and can impair the anticipatory and oral preparatory phases of swallowing. Objective: To characterize swallowing problems and the feeding situation of patients with bvFTD and to correlate the swallowing problems with functionality, executive functions, cognitive and behavioral features. Methods: Consecutive outpatients with bvFTD in mild, moderate and severe dementia stages were recruited along with their caregivers. Patients and caregivers were screened with the following scales: "Mini-Mental State Examination", "Severe Mini-Mental State Examination", "FTLD-modified Clinical Dementia Rating", "Neuropsychiatric Inventory", "Frontal Assessment Battery", "Index of Independence in Activities of Daily Living", "Swallowing Rating Scale" and "Assessment of Feeding and Swallowing Difficulties in Dementia". Results: Overall, thirty patients with bvFTD were included along with their caregivers. Patients with bvFTD showed feeding and swallowing difficulties such as: messy to eat, passivity, coughing and choking, difficulty with some food consistencies and with specific food. Swallowing problems in bvFTD correlated with impaired functionality (p<0.05) and cognition (p<0.05), executive dysfunction (p<0.01) and behavioral features (p<0.01). Caregivers had great difficulty in managing the feeding situation during mealtime, with different characteristics in each dementia stage. Conclusion: Patients with bvFTD had inappropriate speed eating, passivity, coughing and choking starting in the mild dementia stage, and these problems worsen in the severe stage. Such difficulties affected caregiver performance during mealtime. The correlations indicated that swallowing difficulties tend to follow cognitive and behavioral decline in patients with bvFTD.

RESUMO Introdução: Os problemas na situação de alimentação e deglutição podem ocorrer com a progressão da variante comportamental da demência frontotemporal (DFT-vc) e alterar as fases antecipatória e preparatória oral da deglutição. Objetivo: Caracterizar os problemas de deglutição e a situação de alimentação de pacientes com DFT-vc e correlacionar os problemas de deglutição com a funcionalidade, funções executivas, aspectos cognitivos e comportamentais. Métodos: Foram recrutados pacientes ambulatoriais com DFT-vc nas fases leve, moderada e grave da demência, e seus respectivos cuidadores. Os pacientes e cuidadores foram avaliados com as escalas: "Mini-Exame do Estado Mental", "Mini-Exame do Estado Mental Grave", "Escala de Avaliação Clínica da Demência Modificada - DFT", "Inventário Neuropsiquiátrico", "Bateria de Avaliação Frontal", "Índice de Independência nas Atividades da Vida Diária", "Escala Funcional de Avaliação da Deglutição" e "Avaliação das Dificuldades de Alimentação e Deglutição na Demência". Resultados: Foram incluídos 30 pacientes com DFT-vc, e seus cuidadores. Pacientes com DFT-vc apresentaram dificuldades de alimentação e deglutição como: confusão na alimentação, passividade, tosse e asfixia, dificuldades com algumas consistências alimentares e alimentos específicos. Problemas de deglutição na DFT-vc correlacionaram-se com funcionalidade prejudicada (p<0,05) e cognição (p<0,05), disfunção executiva (p<0,01) e características comportamentais (p<0,01). Os cuidadores tiveram grande dificuldade em gerenciar a situação de alimentação diante de diferentes problemas em cada fase da demência. Conclusão: Pacientes com DFT-vc apresentaram velocidade de alimentação inapropriada, passividade, tosse e engasgos já na fase leve da doença, com piora na fase grave. As correlações indicaram que as alterações de deglutição tendem a seguir o declínio cognitivo e comportamental na DFT-vc.

Prevalencia de infección por los virus de la hepatitis B, D y por retrovirus en la etnia Matsés (Loreto, Perú) / Prevalence of retrovirus, hepatitis B and D infection in the Matsés ethnic group in Loreto, Peru

RESUMEN Para determinar la prevalencia de infección por los virus de la hepatitis B y D (VHB y VHD, respectivamente), VIH y HTLV-1/2 en la etnia matsés, después de la inmunización contra el VHB se realizó un estudio transversal y poblacional, utilizando pruebas de ELISA y qPCR en 963 pobladores. Las prevalencias de HBsAg, anti-HBc y anti-HBs fueron 3,3%, 36,0% y 58,7%, respectivamente. En el 3,1% de la población la carga viral fue mayor a 2000 UI/mL. En menores de 10 años, la prevalencia de HBsAg y anti-HBc fue 0,0% y 2,6%, respectivamente, mientras que en el 94,4% se encontraron anticuerpos protectores. La prevalencia de infección por el VIH y el HTLV-1/2 fue 1,5% y 0,6%, respectivamente. Se concluye que existen tasas bajas de infección por el VHB y el VHD en la población infantil de la etnia matsés. Asimismo, se confirma la presencia de infección por el VIH y el HTLV-1/2.

ABSTRACT Observational, cross-sectional, populational study to determine the prevalence of infection by hepatitis B virus (HBV), hepatitis D virus (HDV), human immunodeficiency virus (HIV) and human T-lymphotropic virus type 1 and 2 (HTLV-1/2) in the Matsés ethnic group, after immunization against HBV. ELISA and qPCR tests were used in 963 residents. The prevalence of HBsAg, Anti-HBc and Anti-HBs was 3.32%, 36.03% and 58.67% respectively. In 3.1% of the population the viral load was greater than 2000 IU/mL. In children under 10 years, the prevalence of HBsAg and anti-HBc was 0.0% and 2.6%, respectively, while protective antibodies were found in 94.4%. The prevalence of HIV and HTLV-1/2 infection was 1.5% and 0.6%, respectively. It is therefore concluded that there are low rates of HBV and HDV infection in the Matsés child population. Likewise, the presence of HIV and HTLV-1/2 infection is confirmed.

Reducción en la infección por VHB y VHD en dos poblaciones indígenas de la Amazonia peruana después de la vacunación contra la hepatitis B / Reduction of HBV and HDV infection in two indigenous peoples of Peruvian Amazon after the vaccination against hepatitis B

Resumen: Objetivo: Conocer el resultado de la vacunación contra la hepatitis B en las comunidades hiperendémicas Kandozi y Chapra de la Amazonia Peruana a partir de la prevalencia de infecciones por los virus de la hepatitis B (VHB) y Delta (VHD), ocho años después de iniciada la vacunación. Material y métodos: Se realizó un estudio transversal en 2 944 pobladores de 67 comunidades indígenas Kandozi y Chapra en abril de 2010. El tamizaje serológico para el antígeno de superficie del VHB (HBsAg), anticuerpos anti-HBc IgM e IgG, anticuerpos anti-HBs y anti-VHD se determinaron mediante pruebas de ELISA. Resultados: Las tasas de prevalencia del HBsAg, anti-HBc IgG, anti-HBs ≥10 mlUI/ml y anti-VHD fueron 2.3, 39.13, 50.95 y 2.11%, respectivamente. La prevalencia del HBsAg en niños <11 años fue cero. Entre los portadores del HBsAg, las tasas de prevalencia de sobreinfeccion por el VHD e infección aguda por el VHB fueron 2.11% (todos fueron >14 años) y 11.94%, respectivamente. Conclusiones: Estos hallazgos muestran la eliminación de portadores de VHB en niños <11 años, ocho años después de iniciada la vacunación contra el VHB.

Abstract: Objective: To determine the outcome of the vaccination against hepatitis, we determined the prevalence of hepatitis B virus (HBV) and hepatitis D virus (HDV) infections, eight years after introduction of the vaccination. Materials and methods: A cross-sectional study was performed in 2 944 participants of 67 Kandozi and Chapra indigenous peoples in April 2010. Serological screening for hepatitis B surface antigen (HBsAg), antibody anti-HBc IgM and IgG, antibody anti-HBs and anti-HDV were determined by ELISA tests. Results: The prevalence rates of HBsAg, anti-HBc total, anti-HBs ≥10 mlUI/ml and anti-HDV were 2.3, 39.13, 50.95 and 2.11%, respectively. The prevalence rate of HBsAg in children <11 years was 0%. Among carriers of HBsAg, the prevalence rates of HDV and acute HBV infections were 2.11% (all were >14 years) and 11.94%, respectively. HBsAg and anti-HBc total were associated with individuals ≥10 years (p<0.001). Conclusions: These findings show the elimination of HBV carriers in children <11 years, eight years following introduction of the vaccination against HBV.

Circadian variation of fatigue in both patients with paralytic poliomyelitis and post-polio syndrome / Variacao circadiana da fadiga em ambos os grupos de pacientes com poliomielite paralitica e sindrome pos-poliomielite

Objective It was to evaluate the degree of fatigue in patients with paralytic poliomyelitis (PP) and with post-polio syndrome (PPS), and correlate it with parameters of sleep and the circadian cycle. Methods Thirty patients, 17 female (56.7%), participated in the study: they answered the Revised Piper Fatigue Scale and performed a nocturnal polysomnographic study. Eleven had PP (mean age±standard deviation of 47.9±6.4 years), and 19 had PPS (mean age±standard deviation of 46.4±5.6 years). Results Our study showed that fatigue was worse in the afternoon in the PP Group and had a progressive increase throughout the day in the PPS Group. We also observed compromised quality of sleep in both groups, but no statically significant difference was found in the sleep parameters measured by polysomnography. Conclusion Fatigue has a well-defined circadian variation, especially in PPS Group. Poor sleep quality is associated with fatigue and, therefore, sleep disturbances should be evaluated and treated in this group of PPS. .

Objetivo Foi avaliar o grau de fadiga em pacientes com poliomielite paralítica (PP) e com síndrome pós-poliomielite (SPP), e correlaciona-lo com parâmetros de sono e ciclo circadiano. Método Trinta pacientes, 17 do sexo feminino (56,7%), participaram do estudo: responderam à Escala de Fadiga de Piper Revisada e submeteram-se à avaliação polissonográfica noturna. Onze apresentavam PP (média de idade±desvio padrão de 47,9±6,4 anos), e 19 apresentavam SPP (média de idade±desvio padrão de 46,4±5,6 anos). Resultados Nosso estudo mostrou que a fadiga é pior no período da tarde no grupo com PP e piora progressivamente ao longo do dia no grupo SPP. Observamos também comprometimento na qualidade do sono em ambos os grupos. Contudo, os parâmetros do sono avaliados pela polissonografia não demonstraram diferenças estatísticas significantes entre os grupos PP e SPP. Conclusão A fadiga apresenta variação circadiana bem definida, especialmente nos pacientes do grupo SPP. Pobre qualidade do sono está associada com fadiga e, portanto, distúrbios do sono deveriam ser mais bem avaliados e tratados no grupo de pacientes com SPP. .

Calidad de vida en cáncer de mama: validación del cuestionario BR23 en Chile / Validation of BR23 questionnaire for the assessment of quality of life of breast cancer patients in Chile

Background: Quality of Life assessment in oncologic patients evaluates the impact ana sequels of the disease ana the adverse effects of available treatments. Aim: To validate in Chile the breast cáncer specific-questionnaire (BR23) developed by the European Organization for Research and Treatment of Cancer (EORTC). Patients and Methods: After performing a linguistic validation of the BR23 according to EORTC instructions, its psychometric properties were tested in 103 patients with breast cancer whose ages ranged from 34 to 83 years. Infernal consistency ofthe scales was assessed using the Cronbach's alpha coefficient. The test-retest correlations of each scale (n = 83) were evaluated. The correlation ofBR23 scales with SF36 version 2 and C30 version 3.0 scales was also assessed. The sensitivity and specificity of the instrument were analyzed using receiver operating characteristic curves (ROC). Results: Alpha values showed acceptable levels of internal consistency, ranging between 0.702 and 0.917 in all scales of BR23. The statistical analysis revealed significant test-retest correlations in most scales ofBR23. The correlations between BR23 and similar domains of C30 and SF36 questionnaires were also significant. The BR23 questionnaire demonstrated satisfactory levels of sensitivity and specificity when compared with the SF-36 scale. Conclusions: The BR23 questionnaire adapted for use in Chile is linguistically appropriate and psychometrically valid.

Frequency and clinical manifestations of post-poliomyelitis syndrome in a brazilian tertiary care center / Frequência e manifestações clínicas da síndrome pós-poliomielite em um centro terciário brasileiro

OBJECTIVE: To determine the frequency and clinical manifestations of patients with post-poliomyelitis syndrome (PPS) in a Brazilian division of neuromuscular disorders. METHODS: A total of 167 patients with prior history of paralytic poliomyelitis was investigated for PPS, based on international diagnostic criteria. Other variables analyzed were: gender, race, age at poliomyelitis infection, age at PPS onset, and PPS symptoms. RESULTS: One hundred and twenty-nine patients presented PPS, corresponding to 77.2% of the studied population. 62.8% were women and 37.2% were men. Mean age of patients with PPS at onset of PPS symptoms was 39.9±9.69 years. Their main clinical manifestations were: new weakness in the previously affected limbs (69%) and in the apparently not affected limbs (31%); joint pain (79.8%); fatigue (77.5%); muscle pain (76%); and cold intolerance (69.8%). CONCLUSIONS: Most patients of our sample presented PPS. In Brazil, PPS frequency and clinical features are quite similar to those of other countries.

OBJETIVO: Determinar a frequência e as manifestações clínicas de pacientes com síndrome pós-poliomielite (SPP) em um setor terciário de doenças neuromusculares brasileiro. MÉTODOS: Um total de 167 pacientes com história prévia de poliomielite paralítica foi estudado para diagnóstico de SPP, de acordo com critérios diagnósticos internacionais. Além da SPP, as variáveis analisadas foram: gênero, raça, idade à época da poliomielite aguda e idade no início dos sintomas da SPP. RESULTADOS: Cento e vinte e nove pacientes apresentaram SPP, correspondendo a 77,2% da população estudada. Mulheres constituíram 62,8% dos pacientes e os homens, 37,2%. A média de idade dos pacientes com SPP à época do início dos sintomas foi de 39,9±9,69 anos. Suas principais manifestações clínicas foram: manifestações novas de fraqueza em membros previamente afetados (69%) e em membros aparentemente não afetados (31%); dores articulares (79,8%); fadiga (77,5%); dor muscular (76%) e intolerância ao frio (69,8%). CONCLUSÕES: A maioria dos pacientes da presente casuística apresentou SPP. No Brasil, a frequência e as características clínicas da SPP são similares às observadas em outros países.

Clinical correlates of the restless legs syndrome / Correlações clínicas da síndrome das pernas inquietas

OBJECTIVE: To determine the clinical correlates of the restless legs syndrome (RLS) in a Brazilian sleep disorders center. METHODS: We retrospectively studied 118 patients with RLS from January, 2004, to December, 2010. The analyzed variables were: age at disease onset, gender, race, years of school instruction, primary and secondary RLS, and treatment options. RESULTS: Among the studied patients, 83.9% were women with a female/male sex ratio of 5:1. Mean age of the patients at symptom onset ± standard deviation was 41.7±17.9 years-old. The primary RLS was found in 85% of patients. The other 15% remainders consisted of secondary forms, and they were associated with neuropathy, iron deficiency anemia, end-stage renal disease, or Parkinson's disease. Drug therapy for RLS was introduced in 67% of patients. CONCLUSIONS: Most patients presented primary RLS with an early disease onset. Further epidemiological studies are welcomed to provide better information on secondary RLS in Brazil.

OBJETIVO: Determinar as correlações clínicas da síndrome das pernas inquietas (SPI) em um centro brasileiro de distúrbios de sono. MÉTODOS: Foram estudados retrospectivamente 118 pacientes com SPI atendidos entre janeiro de 2004 e dezembro de 2010. As variáveis analisadas compreendiam: idade ao início da doença, sexo, raça, escolaridade, SPI primária e secundária e tratamento da SPI. RESULTADOS: Do total de pacientes estudados, 83,9% eram mulheres e a razão mulher∕homem foi de 5:1. A média de idade dos pacientes ± desvio padrão de quando iniciaram sintomas da SPI foi de 41,7±17,9 anos. Oitenta e cinco por cento dos pacientes apresentaram SPI primária. Os restantes 15% apresentaram a forma secundária, que estava associada à neuropatia periférica, anemia por deficiência de ferro, insuficiência renal crônica e doença de Parkinson. Foi introduzida medicação para SPI em 67% dos pacientes. CONCLUSÕES: A maioria dos pacientes apresentou SPI primária com início precoce da doença. Mais estudos epidemiológicos são necessários para prover informações sobre as causas secundárias de SPI no Brasil.

Epidemiology of primary and secondary headaches in a Brazilian tertiary-care center

OBJETIVO: Analisar os aspectos demográficos da população em estudo, o tempo decorrido desde o início da queixa de cefaléia até a busca pelo serviço, assim como o diagnóstico das cefaléias primárias e secundárias. MÉTODO: 3328 pacientes foram analisados retrospectivamente de acordo com sexo, idade, raça, escolaridade, tempo decorrido entre o início da cefaléia e a busca ao médico e diagnóstico (ICHD-II, 2004). RESULTADOS: A razão Mulher/Homem foi 4:1, ambos com média de idade 40,7±15anos, não havendo diferença significativa entre os sexos. Aproximadamente 65% dos pacientes eram brancos e 55% tinha menos de 8 anos de escolaridade. A duração da queixa de cefaléia até a primeira consulta foi de 1 a 5 anos em 32,99% dos pacientes. Os diagnósticos mais prevalentes foram: migrânea (37,98%), cefaléia do tipo tensional-CTT (22,65%) e cefaléia em salvas (2,73%). CONCLUSÃO: Existem poucos dados epidemiológicos de pacientes atendidos em serviços terciários, principalmente em países subdesenvolvidos. De acordo com a literatura, a migrânea foi mais prevalente que a CTT. Também é relevante observar a baixa escolaridade da população, assim como o grande tempo de espera até a primeira consulta. Um número incomum de pacientes com síndrome de cefaléia hípnica foi observado na amostra.

Microcirugía vascular cuando no hay vasos venosos utilizables en el cuello / Vascular microsurgery when there aren't usable venous vessels in the neck

La reconstrucción microquirúrgica de los grandes defectos posteriores a terapia resectiva en cáncer de cabeza y cuello ha sido un gran aporte que ha permitido mejorar resultados funcionales, estéticos y quirúrgicos de estos pacientes. Presentamos un caso clínico de reconstrucción microquirúrgica cervical en el cual no habían vasos receptores en el cuello, mostrando la solución mediante la utilización de un vaso recipiente que se encontraba fuera del territorio cervical: la vena cefálica
