Measurement of stigma and associated characteristics in people with tuberculosis in Medellín, Colombia: a cross-sectional study.

BACKGROUND: Stigma towards tuberculosis (TB) delays diagnosis and compromises adherence to treatment. We measured the degree of stigma and identified the sociodemographic and clinical characteristics that were associated with a higher degree of stigma in patients with pulmonary and extrapulmonary TB in Colombia. METHODS: We conducted a cross-sectional study with 232 participants included in the TB control program in 2017. Sociodemographic and clinical variables were measured. The stigma component was measured through a validated scale and a multiple linear regression was used. RESULTS: The study analysed 232 patients, of which 52.2% were men, 53.5% were between 27 and 59 y of age and 66.8% had a basic-medium education level. Two characteristics were significantly related to a higher stigma score: the basic-medium education level and homeless status. Homeless status increased the stigma score by 0.27. In contrast, the adjusted stigma score decreased by 0.07 if the patient's health status was perceived as 'healthy'. CONCLUSION: Stigma is maximized in homeless patients and patients with a low education level. It is minimized in patients who perceive their state of health as 'healthy'.

Tuberculosis screening indicators in indigenous population in Colombia: a mixed methods research.

This study aims to evaluate, via a mixed methods study, the implementation of the screening process for pulmonary tuberculosis (PTB) within indigenous population of the Department of Cauca, Colombia, during the 2016-2018 period. Indicators assessing the PTB screening process were elaborated and estimated. Subsequently, an evaluation of the indicators were performed based on a sampling process from health care providers of the municipalities with the highest and lowest PTB incidence and from key agents' perspective. Screening indicators were estimated and thematic analysis was performed based on the interviews conducted with key agents. Finally, a triangulation of quantitative and qualitative findings was performed. From the total population expected to have respiratory symptomatics (n = 16,711), the health care providers were able to identify 42.3% of them. Out of the individuals identified as respiratory symptomatics (n = 7,064), they were able to examine 93.2% (n = 6,585) with at least one acid-fast bacilli smear test. The reported positivity index from acid-fast bacilli smear test was 1.87%. The explanations from key agents revolved around the possibility of an overestimated targeted amount of respiratory symptomatics; insufficient personnel for the search of symptomatic individuals; high costs for the search in areas of difficult access; the need to request permissions from indigenous authorities; culturally ingrained stigma; use of traditional medicine and self-medication; and patient's personal beliefs. This study revealed barriers in the implementation of the screening process for PTB within the indigenous population from the Department of Cauca, mainly in the identifying process of the respiratory symptomatics.

El objetivo fue evaluar la implementación del proceso y los indicadores en las pruebas para detectar tuberculosis pulmonar (TBP) en población indígena del Departamento de Cauca, Colombia, durante el periodo de 2016-2018, a través de un estudio de métodos mixtos. Fueron elaborados y estimados indicadores para el tamizaje de TBP. Posteriormente, a través de un proceso de muestreo de los proveedores de cuidados de salud de las municipalidades con las incidencias más altas y más bajas de TBP, y desde la perspectiva de actores clave, se intentó encontrar una explicación para los resultados de la primera fase. Se estimaron los indicadores de las pruebas y se realizó un análisis temático de las entrevistas dirigidas a los actores clave. Finalmente, se realizó la triangulación de los hallazgos cuantitativos y cualitativos. Del total de sintomáticos respiratorios esperados (n = 16.711), los proveedores de servicios de salud fueron capaces de identificar a un 42,3% de ellos, y de estos sintomáticos respiratorios identificados (n = 7.064) fueron capaces de examinar un 93,2% (n = 6.585) con al menos una prueba de frotis de bacilos ácidorresistentes. El índice de positividad informado en la prueba de la flema analizada en el microscopio, mediante la prueba de frotis de bacilos ácidorresistentes, fue 1.87%. Las explicaciones de los actores clave giraron alrededor de la percepción de un objetivo posiblemente sobreestimado de sintomáticos respiratorios; insuficiente personal para la consulta; altos costes para las consultas en áreas geográficas de difícil acceso; solicitud de permisos a las autoridades indígenas; estigma; medicina tradicional, automedicación y creencias. Este estudio reveló barreras en la implementación de las pruebas para la TBP en la población indígena del Departamento de Cauca, principalmente en el proceso de identificación de sintomáticos respiratorios.

O estudo teve como objetivo avaliar a implementação do processo e os indicadores de triagem para tuberculose pulmonar (TBP) numa população indígena do Departamento de Cauca, Colômbia, no período 2016-2018. Foi realizado um estudo com métodos mistos. Foram elaborados e estimados os indicadores para triagem da TBP. Em seguida, procurou-se explicar os achados da primeira fase, com base em um processo de amostragem de provedores de saúde dos municípios com os coeficientes mais altos e mais baixos de incidência de TBP, e da perspectiva dos atores-chave. Os indicadores de triagem foram estimados e a análise foi realizada das entrevistas com os atores-chave. Finalmente, foi feita a triangulação dos achados quantitativos e qualitativos. Do total de sintomáticos respiratórios esperados (n = 16.711), o provedor de saúde conseguiu identificar 42,3%, e destes sintomáticos respiratórios identificados (n = 7.064) conseguiram examinar 93,2% (n = 6.585) com pelo menos um exame de escarro (teste de BAAR). O índice de positividade do teste de BAAR foi de 1,87%. As explicações dos atores chave giraram em torno da percepção de uma proporção possivelmente superestimada de sintomáticos respiratórios, pessoal insuficiente para a busca, custos elevados da busca em áreas de difícil acesso geográfico, solicitação de autorização pelas autoridades indígenas, estigma, medicina tradicional, automedicação e crenças. O estudo revelou barreiras para a implementação da triagem para TBP na população indígena do Departamento de Cauca, principalmente no processo de identificação de sintomáticos respiratórios.

Tuberculosis care cascade for the indigenous population in Colombia: an operational research study.

OBJECTIVE: Construct and evaluate the care cascade for pulmonary tuberculosis in the indigenous population of the department of Cauca (Colombia) and identify existing gaps. METHODS: Mixed-methods sequential explanatory design. In the first phase, the pulmonary tuberculosis care cascade for the indigenous population of Cauca was evaluated. Data were obtained from secondary sources and all cases diagnosed from 1 January 2016 to 31 December 2017 were included. In the second phase, semi-structured interviews were done with nine program coordinators and 11 nursing auxiliaries to explain identified gaps. Absolute and percentage values were estimated for each of the steps and gaps in the care cascade. Quantitative and qualitative results were triangulated. RESULTS: In 2016 and 2017, an estimated 202 patients with respiratory symptoms were expected to be positive and 106 cases of pulmonary tuberculosis were reported among the indigenous population of the department of Cauca. A gap of 47.5% was found for diagnosis, since only 52.5% of subjects were diagnosed in health services. This gap was explained by poor quality of samples and flawed smear techniques; flaws in correct identification of patients with respiratory symptoms; limited access to diagnostic methods, such as culture and molecular tests; and limited training and high turnover of personnel in health service provider institutions. CONCLUSIONS: The tuberculosis control program should focus actions on bridging the gap in case detection in the indigenous population.

Portanto, identificamos uma lacuna diagnóstica de 47,5%, já que apenas 52,5% dos casos receberam um diagnóstico nos serviços de saúde. As explicações para esta lacuna foram a má qualidade das amostras e falhas na técnica de esfregaço, falhas na identificação correta dos sintomas respiratórios, acesso limitado aos métodos de diagnóstico, tais como cultura e testes moleculares, bem como capacitação deficiente e alta rotatividade de pessoal nas instituições de saúde. Conclusões. As ações do programa de controle da tuberculose devem se concentrar em reduzir a lacuna na detecção de casos na população indígena.

Therapeutic options for primary meningeal angiosarcoma: A case report.

BACKGROUND: Primary angiosarcoma (AS) of the central nervous system (PACNS) is an extremely rare malignancy. The meninges represent an uncommon site of origin of PACNS. This report describes a recurrent meningeal PACNS treated with surgery, radiotherapy, stereotactic radiosurgery, and paclitaxel at different stages of the disease. CASE DESCRIPTION: A 36-year-old Asian male presented to our facility with a 4-month history of worsening headaches and complete right homonymous hemianopia. Neuroimaging revealed a left occipital lobe hematome with an underlying left tentorial tumor. After subtotal resection, neuropathological examination revealed features of a malignant endothelial cell AS. He received a course of adjuvant radiation therapy but experienced disease progression. He subsequently received additional stereotactic radiosurgery followed by weekly paclitaxel. Magnetic resonance imaging during the course of treatment revealed stable disease until patient died following another progression of his tumor. CONCLUSION: This case of a meningeal PACNS highlights the importance of considering this entity in the face of a malignant lesion presenting with intracranial hemorrhagic activity. Our observations suggest that the use of paclitaxel provided a modest clinical response in PACNS, highlighting the need to consider a combined approach structured mainly on surgery and radiotherapy. Stereotactic radiosurgery appears to be a promising treatment option.

Características clínicas y patológicas de pacientes con tumores del sistema nervioso central en un centro en Suramérica desde 2010 hasta 2015 / Clinico-pathological characteristics of central nervous system tumors in a South American center from 2010 to 2015

Resumen Objetivo: Caracterizar los pacientes diagnosticados con tumores del sistema nervioso central en el Instituto Neurológico de Colombia durante el periodo 2010-2015. Métodos: Estudio descriptivo retrospectivo. Para los tumores primarios se usó la clasificación de la Organización Mundial de la Salud y para los metastásicos se usó la Clasificación Internacional de Enfermedades en Oncología. Resultados: Se identificaron 288 pacientes, 194 de ellos con tumores primarios y 94 tumores metastásicos. No se lograron clasificar los tumores primarios en el 23,7 % de los casos y para los metastásicos no se obtuvo la clasificación morfológica (histológica) en el 35,1 % de los casos. Los hombres presentaron con mayor frecuencia tumores de comportamiento maligno tipo glioblastoma NEO (no especificado de otra manera) (14,9 %) y en las mujeres predominaron los tumores de comportamiento benigno tipo meningioma (23,2 %). En mayores de 65 años, tanto el glioblastoma NEO como el meningioma fueron más frecuentes en mujeres con 17,4 % y 28,3 %, respectivamente. Entre los pacientes con tumores metastásicos, de acuerdo con la clasificación topográfica, los tumores primarios más frecuentes se localizaron en pulmón (39,4 %) y mama (17 %). No se identificó el sitio primario de metástasis en el 11,7 % de los casos. La histología más comúnmente identificada fue el adenocarcinoma (14,9 %), seguido del carcinoma (8,5 %). Conclusiones: Para una vigilancia efectiva de la enfermedad es necesario realizar un monitoreo epidemiológico y clínico de tumores primarios y metastásicos, mediante el uso de registros institucionales de cáncer, incluyendo datos topográficos, histológicos y moleculares, según disponibilidad.

Abstract Objective: The aim of this study was to characterize patients with a diagno- sis of a central nervous system (CNS) tumors at the Instituto Neurologico de Colombia during the period between 2010 to 2015. Methods: A retrospective descriptive study was conducted. The Classification of the World Health Organization was used for CNS primary tumors whereas the International Classification of Diseases for oncology (ICD-O) was used for CNS metastatic tumors. Results: 288 patients were identified, 194 of them with primary tumors of CNS and 94 with metastatic tu- mors from systemic cancer. It was not possible to classify primary tumors in 23.7% of the cases and regarding the metastatic tumors it was not possible to obtain the classification in 35.1 % of the cases. Men presented more frequently tumors of ma- lignant behavior such as glioblastoma NOS (not otherwise specified) (14.9 %) while in women benign behavior tumors such as meningioma predominated (23.2 %). For population older than 65 years old, both glioblastoma NOS and meningioma were more frequent in women with 17.4 % and 28.3 %, respectively. In patients with CNS metastatic tumors, according to the topographic classification, the most frequent primary tumors were lung (39.4 %), followed by breast (17 %). Its origin was not iden- tified in 11.7 % of the cases. The most identified histology was adenocarcinoma (14.9 %), followed by carcinoma (8.5 %). Conclusion: For disease surveillance, it is necessary to complete epidemiological and clinical monitoring of primary and metastatic tumors of the CNS by using institutional cancer registries including topographic, histological and molecular data according to availability.

Delays in diagnosing pulmonary tuberculosis within a context of medium incidence, Medellín, Colombia, 2017: an operational research.

BACKGROUND: Delay in tuberculosis (TB) diagnosis is one of the first obstacles for controlling the disease. Delays generate greater deterioration of the health of the patients and increase the possibilities of transmission and infection at home and in the community. The aim of the study was to identify profiles and individual variables associated with patient delays and health care system delays in patients with pulmonary tuberculosis (PTB) in Medellín, Colombia, a city that notifies 1400 new cases per year. METHODS: A retrospective cohort study in adults with PTB was conducted from May to September of 2017. Sociodemographic, health care-seeking behaviour, and clinical variables were measured. The outcomes were patient delay and health care system delay. The data were obtained from records of the local TB program, and a questionnaire was applied by the health care team that performs routine field visits. Simple correspondence analysis was used to identify groups (profiles), and their characteristics. Cox's proportional hazards model was carried out to identify the variables associated with the delays. RESULTS: The study included 183 patients. The total delay median was 101 days (IQR: 64-163). Patient delay was of 35 days (IQR: 14-84), the profile with greater delay belonged to consumers of psychoactive substances. The health care system delay was of 27 days (IQR: 7-89), the attributes of the profile with greater delay were being a female, having more than two consultations before the diagnosis, and having prescribed antibiotics. Basic-medium educational level [HRa = 0.69; 95% CI (0.49-0.97)] and having a TB home contact [HRa = 0.68; 95% CI (0.48-0.96)] were associated with greater patient delay. Having negative acid-fast bacilli (AFB) smear [HRa = 0.64; 95% CI (0.45-0.92)] and more than two consultations before the diagnosis [HRa = 0.33; 95% CI (0.22-0.49)] was associated with greater health care system delay. CONCLUSIONS: Data from epidemiological surveillance allowed locating risk groups with delays in TB diagnosis which requires the prioritisation of the local TB control program to promote early detection and prevention of adverse outcomes.

Textiloma Mimicking a Recurrent High-Grade Astrocytoma: A Case Report.

Introduction Textiloma (Txm) is a nonmedical term that has been given to foreign body-related inflammatory pseudotumor arising from retained nonabsorbable cotton matrix that is either inadvertently or deliberately left behind during surgery, which may trigger an inflammatory reaction. This report describes a case of Txm mimicking a recurrent high-grade astrocytoma. Case Report We, here, present the case of a 69-year-old female with a 6-month history of progressive left-sided weakness. Neuroimaging studies revealed a large nonenhancing mass in the right frontoparietal lobe. Pathology reported a World Health Organization tumor classification grade II, diffuse astrocytoma. After surgical intervention, external beam radiation was given to the remaining areas of residual tumor. Routine magnetic resonance imaging (MRI) revealed a nodular area of contrast enhancement in the dorsal and inferior margin of the biopsy tract, growing between interval scans, and perfusion-weighted imaging parameters were elevated being clinically asymptomatic. She underwent a complete resection of this area of interest and pathology returned as a Txm with Surgicel fibers. Conclusion After treatment of a neoplasm, if unexpected clinical or imaging evidence of recurrence is present, a foreign body reaction to hemostatic material used during the initial surgery should be included in the differential diagnosis.

Psychogenic non-epileptic and epileptic seizures: clues for a differential diagnosis. Findings from a Colombian study / Crisis psicógenas no epilépticas y crisis epilépticas: pistas para un diagnóstico diferencial. Hallazgos de un estudio colombiano

Introduction. Psychogenic non-epileptic seizures (PNES) are paroxysmal changes in behavior that resemble epileptic seizures, although they have no electrophysiological correlation or clinical evidence of epilepsy. Aim. To compare clinical and sociodemographic characteristics of patients diagnosed with PNES-alone and PNES-andepilepsy. Patients and methods. A cross-sectional study of consecutive patients diagnosed with PNES in a 20-month period was carried out. A video-EEG was performed in all patients. Socio-demographical, clinical and semiological characteristics were compared between those patients with and without concomitant epilepsy. Results. Sixty-five patients were included, 35 (53.9%) had PNES-alone and 30 (46.1%) had PNES-and-epilepsy. The proportion of women in the study was 70.8%. The median age at seizure onset was 16 years. A late start was recorded in PNES-alone group (23 years) compared to PNES-and-epilepsy group (11 years), however, it was not significant. There was a lower frequency of antiepileptic drugs use in the PNES-alone group compared with the PNES-and-epilepsy group. The most frequent semiological features were the gradual onset of events (69.2%) and the duration longer than two minutes (63.1%). Conclusion. The waxing and waning pattern during paroxysmal events suggest a non-epileptic origin. However, it is not uncommon to find patients with concomitant epileptic seizures

Introducción. Las crisis psicógenas no epilépticas (CPNE) son cambios paroxísticos en el comportamiento que se asemejan a las crisis epilépticas, aunque no tienen correlación electrofisiológica ni evidencia clínica de epilepsia. Objetivo. Comparar las características clínicas y sociodemográficas entre pacientes diagnosticados con CPNE, con y sin epilepsia concomitante. Pacientes y métodos. Estudio transversal de pacientes consecutivamente diagnosticados de CPNE durante un período de 20 meses. A todos los participantes se les realizó un videoelectroencefalograma (video-EEG). Se compararon las características sociodemográficas, clínicas y semiológicas entre los que presentaban y los que no presentaban epilepsia concomitante. Resultados. Se incluyó a 65 pacientes, 35 con CPNE (53,9%), y 30 con CPNE y epilepsia (46,1%). La edad mediana en el inicio del video-EEG fue de 33 años, y un 70,8% eran mujeres. La edad mediana de inicio de las crisis fue de 16 años. En el grupo de CPNE hubo un inicio más tardío (23 años) en comparación con el grupo de CNPE y epilepsia (11 años), pero la diferencia no fue significativa. La proporción de pacientes en terapia con fármacos antiepilépticos fue significativamente mayor en el grupo con CPNE y epilepsia comparado con el grupo con CPNE. Las características semiológicas más frecuentemente encontradas fueron el inicio gradual de las crisis (69,2%) y una duración de más de dos minutos (63,1%). Conclusión. La variabilidad en los síntomas sugiere un origen no epiléptico de los eventos paroxísticos, los cuales se presentan frecuentemente en pacientes con epilepsia

Actualización sobre factores de riesgo para cefalea pospunción dural / Update on risk factors for post-dural puncture headache

INTRODUCCIÓN: La cefalea pospunción dural es la complicación más frecuente de la punción dural, reportando una incidencia que oscila entre el 10% y el 40%. El padre de la anestesia epidural, August Bier, reportó en 1899 el primer caso de cefalea pospunción dural atribuyéndola a la perdida de líquido cefalorraquideo. Existen dos teorías para explicar su origen; la primera es la teoría de la grieta y la segunda es la teoría de Monro-Kellie-Burrows. El conocimiento de los factores de riesgo permite predecir la probabilidad de desarrollar esta patología. OBJETIVO: Revisar la evidencia actual sobre los factores de riesgo implicados en su desarrollo. METODOLOGÍA DE BÚSQUEDA: Se realizó una búsqueda de la literatura en PubMed, Proquest, Biblioteca Virtual en Salud en el periodo comprendido entre el 14 y 30 de Noviembre del 2014. CONCLUSIONES: La edad, sexo femenino, antecedente personal de cefalea pospunción dural, aguja traumática y orientación del bisel perpendicular son factores de riesgo con significancia estadística. Mientras que los resultados a partir de los estudios no son concluyentes para factores como bajo peso (IMC<25Kg/m2), antecedente personal de cefalea, mayor calibre de la aguja, no reinserción del estilete y mayor número de intentos por punción

INTRODUCTION: Post-dural puncture headache is the most common complication of dural puncture, reporting an incidence ranging between 10% and 40%. The father of epidural anesthesia, August Bier, reported the first case of post-dural puncture headache in 1899, attributing it to cerebrospinal fluid loss. There are two theories to explain its origin; the first is the theory of the crack and the second is the theory of Monro-Kellie-Burrows. Knowledge of risk factors allows to predict the likelihood of developing this disease. OBJECTIVE: To review the current evidence pertaining to the risk factors involved in its development. RESEARCH METHODOLOGY: Conducted literature research in PubMed, ProQuest, and Virtual Library of Health in the period between the 14th and 30th of November of 2014. CONCLUSIONS: Age, female gender, personal history of post-dural puncture headache, traumatic needle and orientation of perpendicular bevel are all risk factors with statistical significance. While results from other studies were inconclusive for factors such as low weight (BMI<25Kg/m2), personal history of headaches, increased size of needle, no reinsertion of stylet and a high number of attempts to puncture
