La investigación pretendió arrojar datos propios de la forma en que se comunican estudiantes de grados quinto y noveno de dos colegios diferentes de la Secretaría de Educación de Bogotá. Se escogieron dos grupos, los niños de quinto pertenecientes al colegio La Candelaria de la localidad de Santa Fe, que realizaron pinturas en su clase de artes plásticas, a quienes llamamos: artistas. Estas obras las entregaron a un joven de noveno del colegio San Francisco de Asís de la localidad Los Mártires, quien propuso cinco maneras diferentes de divulgar estas obras de arte, este rol es denominado: promotor. El artista al recibir la propuesta donde además, encuentra los datos de contacto del promotor, elige las tres que le parecen más interesantes y lo busca para informarle su decisión. La investigación recogió datos de los medios de comunicación que utilizaron artistas y promotores para acordar las piezas a desarrollar. Durante la investigación apareció una variable con la que no se contaba, la inclusión en el grupo de promotores del San Francisco de Asís, de una estudiante perteneciente al proyecto de aulas hospitalarias, lo que permitió una interacción diferente en medio del grupo, a través de un contacto netamente virtual la situación de salud de la compañera generó en el curso gran sentido de afectación que se evidenció en relaciones empáticas, respetuosas y solidarias, que también se reflejaron en el trato que tuvieron con los artistas."The research pretended to throw own data on how students from fifth and nineth grades, from two different schools of Secretaría de Educación de Bogota get communicated. Two groups were chosen, fifth grade children belonging to school La Candelaria in Santa Fe's locality, who made paintings in their art class, whom we call: artists. These Works were handed over to a school ninth grade student, from San Francisco dc Assis school, in Mártires"" locality, who proposed five different ways to disseminate these art works, this role is called: promoter. The artist, once the proposal was recieved, which also contained the promoter contact information, choose the three options that seem most interesting and seeks the promoter to inform its decision. The research collected data from comunication media, used from both artists and promoters who used to arrange the pieces to develop. During the investigation it appeared a variable that was not counted, the inclusion in the San Francisco's promoter group of a student belonging to the project of hospital classrooms, allowing different among the group interaction, through a purely virtual contact because of the health situation of this girl, wich generated in the course great sense of involvement that was evident in empathic, respectful and supportive relationships, which is also reflected in the deal they had with the artists. It was found that students with an exercise as this one, in soft skills such as problema solver, significantly improve their skills and it w^as found that our students still prefer direct contact."Magíster en EducaciónMaestrí

Aspectos clínicos e epidemiológicos da infecção pelo vírus linfotrópico de células T humanas do tipo 2 (HTLV-II) em São Paulo, Brasil: presença de paraparesia espástica tropical/mielopatia associada ao HTLV em pacientes co-infectados pelo HIV-1

In this study, the epidemiological and clinical features observed in solely HTLV-II-infected individuals were compared to those in patients co-infected with HIV-1. A total of 380 subjects attended at the HTLV Out-Patient Clinic in the Institute of Infectious Diseases "Emilio Ribas" (IIER), São Paulo, Brazil, were evaluated every 3-6 months for the last seven years by infectious disease specialists and neurologists. Using a testing algorithm that employs the enzyme immuno assay, Western Blot and polymerase chain reaction, it was found that 201 (53%) were HTLV-I positive and 50 (13%) were infected with HTLV-II. Thirty-seven (74%) of the HTLV-II reactors were co-infected with HIV-1. Of the 13 (26%) solely HTLV-II-infected subjects, urinary tract infection was diagnosed in three (23%), one case of skin vasculitis (8%) and two cases of lumbar pain and erectile dysfunction (15%), but none myelopathy case was observed. Among 37 co-infected with HIV-1, four cases (10%) presented with tropical spastic paraparesis/HTLV-associated myelopathy (TSP/HAM) simile. Two patients showed paraparesis as the initial symptom, two cases first presented with vesical and erectile disturbances, peripheral neuropathies were observed in other five patients (13%), and seven (19%) patients showed some neurological signal or symptoms, most of them with lumbar pain (five cases). The results obtained suggest that neurological manifestations may be more frequent in HTLV-II/HIV-1-infected subjects than those infected with HTLV-II only.Neste estudo, as características epidemiológicas e clínicas observadas nos indivíduos infectados pelo HTLV-II foram comparadas com os pacientes co-infectados com HIV-1. Um total de 380 indivíduos atendidos na clínica do Ambulatório HTLV do Instituto de Infectologia "Emilio Ribas" (IIER), São Paulo, Brasil, foram avaliados a cada 3-6 meses nos últimos sete anos por especialistas em doenças infecciosas e neurologistas. Usando um algoritmo que emprega ensaio imunoenzimático, Western Blot e reação em cadeia de polimerase, foram incluídos 201 (53%) pacientes infectados pelo HTLV-I e 50 (13%) infectados pelo HTLV-II. Trinta e sete (74%) eram co-infectados pelo HTLV-II e HIV-1. Dos 13 (26%) indivíduos unicamente infectados pelo HTLV-II, infecção do trato urinário foi diagnosticada em três, um com vasculite e em dois casos dor lombar e disfunção erétil mas nenhum caso de mielopatia foi observado. Entre 37 pacientes co-infectados com HIV-1, quatro (10%) casos apresentaram com paraparesia espástica tropical/mielopatia associada ao HTLV similar. Dois casos mostraram paraparesia como sintoma inicial, dois outros casos se apresentaram primeiramente com distúrbios vesical e erétil e as neuropatias periféricas foram observadas em cinco pacientes (13%). Outros sete (19%) pacientes mostraram algum sinal ou sintoma neurológico, a maioria deles com dor lombar (cinco casos). Os resultados sugerem que as manifestações neurológicas podem ser mais freqüentes em indivíduos co-infectados pelo HTLV-II/HIV-1 do que nos indivíduos infectados somente pelo HTLV-II

Contagens de células T CD4+ na co-infecção HIV-1 e HTLV-1: alta prevalência da paraparesia espástica tropical/mielopatia associada ao HTLV-1

INTRODUCTION: HIV positive patients co-infected with HTLV-1 may have an increase in their T CD4+ cell counts, thus rendering this parameter useless as an AIDS-defining event. OBJECTIVE: To study the effects induced by the co-infection of HIV-1 and HTLV-1 upon CD4+ cells. MATERIAL AND METHODS: Since 1997, our group has been following a cohort of HTLV-1-infected patients, in order to study the interaction of HTLV-1 with HIV and/or with hepatitis C virus (HCV), as well as HTLV-1-only infected asymptomatic carriers and those with tropical spastic paraparesis/HTLV-1 associated myelopathy (TSP/HAM). One hundred and fifty HTLV-1-infected subjects have been referred to our clinic at the Institute of Infectious Diseases "Emílio Ribas", São Paulo. Twenty-seven of them were also infected with HIV-1 and HTLV-1-infection using two ELISAs and confirmed and typed by Western Blot (WB) or polymerase chain reaction (PCR). All subjects were evaluated by two neurologists, blinded to the patient's HTLV status, and the TSP/HAM diagnostic was based on the World Health Organization (WHO) classification. AIDS-defining events were in accordance with the Centers for Disease Control (CDC) classification of 1988. The first T CD4+ cells count available before starting anti-retroviral therapy are shown compared to the HIV-1-infected subjects at the moment of AIDS defining event. RESULTS: A total of 27 HIV-1/HTLV-1 co-infected subjects were identified in this cohort; 15 already had AIDS and 12 remained free of AIDS. The median of T CD4+ cell counts was 189 (98-688) cells/mm³ and 89 (53-196) cells/mm³ for co-infected subjects who had an AIDS-defining event, and HIV-only infected individuals, respectively (p = 0.036). Eight of 27 co-infected subjects (30%) were diagnosed as having a TSP/HAM simile diagnosis, and three of them had opportunistic infections but high T CD4+ cell counts at the time of their AIDS- defining event. DISCUSSION: Our results indicate that higher T CD4+ cells count among HIV-1/HTLV-1-coinfected subjects was found in 12% of the patients who presented an AIDS-defining event. These subjects also showed a TSP/HAM simile picture when it was the first manifestation of disease; this incidence is 20 times higher than that for HTLV-1-only infected subjects in endemic areas.INTRODUÇÃO: A possibilidade que a co-infecção pelo vírus da leucemia de células T humana do tipo 1 (HTLV-1) em indivíduos infectados pelo vírus da imunodeficiência humana do tipo 1 poderia falsamente elevar o número de linfócitos T CD4+ no momento do evento definidor de aids, inferindo que essa contagem poderia ser um marcador laboratorial incompleto nos pacientes com a co-infecção HIV-1/HTLV-1. OBJETIVO: Estudar a interação entre o HIV-1 e a co-infecção como o HTLV-1. MATERIAL E MÉTODO: Desde 1997, nosso grupo tem seguido uma coorte de pacientes para estudar a interação entre HIV e/ou vírus da hepatite C (HCV), como também pacientes assintomáticos ou com TSP/HAM. 150 pacientes infectados pelo HTLV-1, encaminhados à clínica de HTLV do Instituto de Infectologia Emilio Ribas, São Paulo, Brasil, foram estudados. Vinte e sete deles estavam co-infectados pelo HIV-1 e HTLV-1, usando dois ELISAs e confirmados tipados pelo WB ou PCR. Todos os pacientes foram avaliados por dois neurologistas, cegos para o status de HTLV e o diagnóstico de TSP/HAM foi baseado na classificação da Organização Mundial de Saúde, 1988. A primeira contagem de células T disponível antes da terapia anti-retroviral foi mostrada para comparar com os pacientes infectados pelo HIV no momento do evento definidor de aids de acordo com Classificação do Centro de controle de Doenças, 1988. RESULTADOS: Um total de 27 HIV-1/HTLV-1 co-infectados foram identificados na coorte, 15 já apresentavam aids e 12 permaneceram sem evento de aids. A mediana de células T CD4 foi de 189 (98-688) células/mm³ e 89 (53-196) células/mm³ nos co-infectados que tinham evento definidor de aids e naqueles com a infecção somente pelo HIV, respectivamente (p = 0,036). Oito dos 27 co-infectados (30%) foram diagnosticados tendo TSP/HAM símile, e três deles mostraram elevada contagem de células T CD4 e apresentaram infecções oportunistas no momento do evento definidor de aids. DISCUSSÃO: Nossos resultados indicam que a contagem de células T CD4+ entre os indivíduos com HIV-1/HTLV-1 foi somente discrepante em 12% desses pacientes e podem ser relacionados à progressão da infecção HTLV-1, e todos mostraram um quadro de TSP/HAM símile como a primeira manifestação de doença. Entretanto, essa taxa de ataque foi 20 vezes mais alta que a observada em pacientes somente infectados pelo HTLV-1 em área endêmica

Presence of tropical spastic paraparesis/human T‐cell lymphotropic virus type 1‐associated myelopathy (TSP/HAM)‐like among HIV‐1‐infected patients

Human immunodeficiency virus type 1 (HIV‐1) and human T‐cell lymphotropic virus types 1 and 2 (HTLV‐1 and ‐2) are retroviruses that share similar routes of transmission and some individuals may have a dual infection. These co‐infected subjects may be at increased risk for tropical spastic paraparesis/HTLV‐1‐associated myelopathy (TSP/HAM)‐like. To study the prevalence of tropical spastic paraparesis/HTLV‐1‐associated myelopathy (TSP/HAM) among co‐infected HIV‐1/HTLV‐1 subjects. Since July 1997, our group has been following a cohort to study the interaction of HTLV with HIV and/or hepatitis C virus (HCV), as well as HTLV‐1‐only infected asymptomatic carriers or those already presenting with TSP/HAM. During these 9 years, 296 HTLV‐1‐infected individuals were identified from a total of 538 patients who were referred to our clinic at the Institute of Infectious Diseases “Emílio Ribas,” in São Paulo, Brazil. All subjects were evaluated by two neurologists, blinded to the HTLV status. TSP/HAM diagnosis was based on Kagoshima diagnostic criteria. Results: A total of 38 HIV‐1/HTLV‐1 co‐infected subjects were identified in this cohort: Twenty‐six had already been diagnosed with AIDS and 12 remained asymptomatic. Six of 38 co‐infected subjects (18%) were diagnosed as having TSP/HAM and also AIDS, and for 5 of them TSP/HAM was their first illness. One additional incident case was diagnosed after 2 years of follow‐up. No modifications on HIV‐1 viral load was seen. In contrast, the co‐infected with TSP/HAM‐like group showed higher HTLV‐1 proviral load (505 ± 380 vs. 97 ± 149 copies/104 PBMC, P = 0.012) than asymptomatic co‐infected subjects, respectively. The incidence of myelopathy among HIV‐1/HTLV‐1 co‐infected subjects is probably higher than among patients infected only with HTLV‐1, and related to a higher HTLV‐1 proviral load. Thus, HTLV‐1/2 screening should be done for all HIV‐1‐infected patients in areas where HTLV‐1 infection is endemic80339239

Corticosteroid therapy in TSP/HAM patients: The results from a 10 years open cohort

Background: The use of corticosteroids for treating tropical spastic paraparesis/HTLV-1 associated myelopathy (TSP/HAM) has yielded controversial results. We report the use of corticosteroids for the treatment of TSP/HAM in an open cohort. Methods: The clinical efficacy of long-term, high dose of corticosteroid therapy was studied in thirty-nine TSP/HAM patients. Disability and motor dysfunction was evaluated based on the Disability Status Scale (DSS), Osame`s Motor Disability Scales (OMDS), and Incapacity Status Scale (ISS), before and after treatment. Treatment included use of methyl-predmisolone, 1 g/day for three days, every 3-4 months. The primary end-point was a change in the scores of the neurological scales from baseline until the fifth visit after therapy. Results: After a mean follow-up of 2.2 years and an average of four pulses per patient, we noted a significant neurological improvement, reaching 24.5% according to the ISS score. No statistically significant differences in scores according to the OMDS and DSS scales were noted. Conclusion: We observed neurological improvement with the use of corticosteroids, with physical therapy and anti spastic-drugs as adjunctive treatment. However, randomized clinical trials should be done to assess the use of corticosteroids and other potentially useful immune-based therapies for TSP/HAM treatment. (C) 2008 Elsevier B.V.

Global economic burden of unmet surgical need for appendicitis

Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
