Introduction En Afrique subsaharienne, les méthodes de diagnostic de la tuberculose sont insuffisantes et reposent essentiellement sur la microscopie. Elles constituent un réel frein pour le contrôle de la tuberculose. La présente étude voudrait évaluer les performances du GeneXpert MTB/RIF vis à vis de la microscopie classique de Ziehl-Neelsen à l’Hôpital Provincial Général de Référence de Bukavu, à l’Est de la République Démocratique du Congo après 10 mois d’utilisation. Méthodes Les résultats de la coloration au Ziehl-Neelsen et de la biologie moléculaire sur GeneXpert MTB/RIF de 452 patients suspects de tuberculose ont été colligés. La validité d’un test par rapport à l’autre dans la détection de la tuberculose a été étudiée. Résultats Dans le groupe entier, la fréquence de la tuberculose pulmonaire était de 16.3%. La positivité était significativement plus élevée pour le GeneXpert MTB/RIF que pour le Ziehl-Neelsen dans le groupe entier (15.9% vs 9.3%, p= 0.03) et chez les séropositifs pour le VIH (52.0% vs 24.0%; p = 0.007). Cependant, la sensibilité de GeneXpert MTB/RIF comparé au Ziehl-Neelsen n’était pas maximale (95.2%). Enfin, GeneXpert MTB/RIF a détecté 20.8% de résistance à la rifampicine. Conclusion La présente étude confirme la supériorité de GeneXpert MTB/RIF sur la coloration de Ziehl-Neelsen dans la détection de la tuberculose et dans la prédiction de la multi résistance. Son utilisation systématique couplée au Ziehl-Neelsen permettrait de mieux contrôler la tuberculose en Afrique subSaharienne. PMID:29187929

L'ostéoarthrite tuberculose est rare au niveau des doigts. Nous rapportons une observation d'atteinte du pouce chez un patient de 55 ans. Il avait présenté une tuméfaction douloureuse du pouce droit suite à un traumatisme du pouce. L’étude bactériologique et une biopsie avaient permis de confirmer le diagnostic. Un traitement antibacillaire de 12 mois avait donné des résultats satisfaisants. Les particularités de la prise en charge sont discutées par rapport aux données de la littérature. PMID:25932075

Le tabagisme et la tuberculose sont deux enjeux majeurs de santé publique au niveau mondial, en particulier dans les pays émergents. Pour déterminer les particularités cliniques, radiologiques, bactériologiques et thérapeutiques de la tuberculose pulmonaire chez les sujets tabagiques nous avons mené une étude prospective au service de phtisiologie de l'hôpital Moulay Youssef sur une période de 10 mois, portant sur 100 nouveaux cas de tuberculose pulmonaire, répartis en 2 groupes, 50 patients tabagiques: Groupe A et 50 patients non tabagiques: Groupe B. Tous nos patients étaient de sexe masculin, l’âge moyen était de 41 ans ± 12 chez le groupe A et de 36 ans ± 16 chez le groupe B. Le délai de consultation était plus long chez les tabagiques, la médiane était de 60j (30; 98) contre 40j (30; 60), la symptomatologie clinique était variable chez les deux groupes, dominée par les expectorations chez les tabagiques 96% contre 60%. Les lésions radiologiques étaient similaires chez les deux groupes ainsi que la charge bacillaire. Tous les patients ont été mis sous traitement antituberculeux. Après un mois du traitement, la Bacilloscopie était négative chez 50% du groupe A contre 66% chez le groupe B. la régression des lésions radiologiques était similaire chez les deux groupes. Le retard diagnostique et le retard de négativation des frottis sont les principales particularités de la tuberculose pulmonaire du sujet tabagique. Le sevrage tabagique doit faire partie intégrante de la prise en charge des patients atteints de tuberculose. PMID:25821545

La tuberculose multifocale a connu un regain de fréquence avec la pandémie du SIDA, elle s'observe encore chez des sujets non infectés par le VIH surtout dans les pays en voie de développement notamment au Maroc. Nous rapportons quatre observations de tuberculose multifocale chez trois patients immunocompétents et un patient immunodéprimé. Quatre patients ont bénéficié d'un bilan phtisiologique, biologique, sérologique(HIV), radiologique et d'angiographie à la fluorescéine pour suspicion de tuberculose multifocale. Il s'agit de trois hommes et une femme, d’âge moyen de 44 ans, trois patients sont immunocompétents et un patient séropositif. La tuberculose intéressait trois localisations chez les quatre patients: pulmonaire dans quatre cas, ophtalmique dans quatre cas, digestive dans un cas, urinaire dans un cas, cérébrale dans un cas et un cas d'atteinte de la moelle osseuse. L'atteinte ophtalmologique est représentée par des nodules choroïdiens de Bouchut dans quatre cas et un nodule papillaire de Bouchut dans un cas; aucun des ces patients ne présentait une uvéite granulomateuse. Nos malades ont reçu un traitement anti-tuberculeux d'une durée de neuf mois avec une bonne évolution clinique, biologique, radiologique et angiographique. Au Maroc, la tuberculose continue à surprendre aussi bien par son extension touchant le sujet débilité et le sujet immunocompétent, que par ses présentations diverses y compris l'atteinte oculaire qu'elle faut rechercher par un examen ophtalmologique soigneux et systématique.

Les localisations ORL extra ganglionnaires de la tuberculose sont rares. La symptomatologie clinique ainsi que les examens paracliniques sont souvent trompeurs,posant ainsi le problème de diagnostic différentiel avec la pathologie tumorale. Nous rapportons 15 cas de localisations extra ganglionnaires de tuberculose, colligés au service ORL et CCF de l'Hopital Militaire Avicenne de Marrakech colligés entre 2009 et 2013. L’âge moyen de nos patients est de 33 ans. L’étude topographique a montré 6 cas au niveau du cavum, un cas de miliaire tuberculeuse pharyngée, 4 cas laryngés; 2 localisations auriculaires; 1 parotidienne et 1 localisation sous maxillaire. Le diagnostic était anatomopathologiquedans tous les cas. Tous nos patients ont reçu un traitement antituberculeux avec une bonne évolution.

Introduction Le mal de Pott est la forme la plus fréquente des tuberculoses ostéo articulaires, le diagnostic de certitude reste difficile. L'imagerie tient une place indéniable dans le diagnostic. L'objectif de cette étude était de déterminer la prévalence de la tuberculose vertébrale et l'apport de la TDM dans le diagnostic. Méthodes Nous avons mené une étude rétrospective sur dossiers de tuberculose vertébrale dans le service de Rhumatologie du CHU de Cocody de Janvier 2006 à Décembre 2013. N'ont pas été inclus dans l’étude, tous les dossiers ne comportant pas d'imagerie. Resultats La prévalence hospitalière de la tuberculose vertébrale était de 10,95%, elle représentait 90,2% de la tuberculose ostéoarticulaire. Elle concernait les 2 sexes, l’âge moyen était de 43,27 ans (4-88ans). L'atteinte dorsolombaire était la localisation la plus fréquente (95,13%). L'atteinte du rachis cervical était rare. La spondylodiscite était fréquente (92,14%). La spondylite (6%) et l'atteinte de l'arc postérieur (0,86%) étaient rares. La spondylodiscite était unique le plus souvent (70,05%), les formes multiétagées ont été notées dans 28,65% des cas, les atteintes mutifocales ont été notées dans14, 63% des cas. Les localisations inhabituelles étaient: atteinte sous occipitale (n=3), atteinte concomitante des 3 segments rachidiens (n=3), atteinte du sacrum (n=1), abcès isolés du psoas (n=4). La prévalence des abcès était de 85,91%, celle des épidurites était de 80,17%. La ponction scannoguidée des abcès a été réalisée dans 20 cas, la recherche de BAAR était positive dans 15 cas. Il existait une tuberculose viscérale évolutive dans 20% des cas. Conclusion La TDM est indéniable dans le diagnostic positif et lésionnel de la tuberculose vertébrale. Le retard au diagnostic explique l’étendue des lésions. PMID:26113932

Introduction A Madagascar, la tuberculose reste un problème de santé publique majeur, l'incidence s’élevant à 16% depuis 2009. Le présent travail a pour objet d'identifier les facteurs de risque de tuberculose chez l'enfant. Méthodes Nous avons mené une étude rétrospective de type cas-témoins sur les facteurs de risque de la tuberculose chez les enfants de 0 à 15 ans au Centre Hospitalier Universitaire Mère-Enfant de Tsaralalàna, de Janvier 2009 à Décembre 2011. Les enfants diagnostiqués de tuberculose dont le diagnostic a été retenu par des éléments de certitude ou par le score pédiatrique de la tuberculose représentent les cas. Les enfants hospitalisés durant la même période, non tuberculeux et de même âge, sont classés témoins. L'Odds Ratio quantifie les associations. Résultats Au total, 91 cas et 173 témoins ont été inclus. Parmi les cas, 73,62% présentent une malnutrition. De fortes associations sont démontrées avec: la malnutrition sévère (OR=6 (IC95% 2,43-15,61 (p<10-5))); le contage tuberculeux (OR=4,71 (IC95% 1,76-12,7 (p=0,003))); la non vaccination par le BCG (OR=4,21 (IC95% 1,99-8,99 (p < 2.10-5))); le niveau intellectuel maternel bas (OR=4,17 (IC95% 0,67-28,14 (p=0,06))); la taille de la fratrie à partir de 5 (OR=4,5). Des associations faibles sont retrouvées pour les autres facteurs étudiés. Les cas présentent une létalité de 18,7% contre 6,3% chez les témoins (p<10-5); 64,7 % des décès sont dus aux formes méningées. Conclusion La tuberculose reste un fléau chez les enfants, avec une lourde responsabilité de la pauvreté rassemblant presque tous les facteurs sus-cités. PMID:25838852

La tuberculose ganglionnaire est la localisation extra-pulmonaire la plus fréquente de la tuberculose. Nous nous proposons dans ce travail d’étudier les modalités diagnostiques, thérapeutiques et évolutives de cette localisation. Il s'agit d'une étude rétrospective portant sur 100 cas de tuberculose ganglionnaire. L’âge moyen était de 35 ± 15 ans (15-85 ans). Aucun malade n’était VIH positif. L'aire cervicale était la plus touchée (93 cas). L'intradermo-réaction à la tuberculine était positive dans 76/91 cas (83,5%). L'examen bactériologique des prélèvements au niveau des ganglions atteints avait mis en évidence des bacilles acido-alcoolo-résistants à l'examen direct dans 2/31 cas (6,4%) et la culture avait isolé Mycobacteruim tuberculosis dans 1/31 cas (3,2%). La cytoponction ganglionnaire (FNAC) était évocatrice de tuberculose dans 35/42 cas (83,3%). La biopsie ganglionnaire était réalisée dans 69 cas et avait permis de retenir le diagnostic de tuberculose dans tous les cas. La FNAC, comparativement à la biopsie, avait permis de raccourcir significativement le délai de la prise en charge (15,1 vs 22,8 jours; p=0,001) et la durée d'hospitalisation (17,3 vs 24,6; p=0,004). La durée moyenne du traitement antituberculeux était de 9,8 ± 4,6 mois (7 à 44 mois). Le traitement chirurgical initial avait raccourci significativement la durée du traitement médical. Il n'avait pas d'impact sur le taux de guérison. Nous avons noté 10 cas de réponse paradoxale aux antituberculeux, quatre cas de résistance clinique et une rechute dans deux cas. La tuberculose ganglionnaire pose un problème diagnostique et thérapeutique. La microbiologie est d'un faible apport. La FNAC est un moyen diagnostique très utiles dans les pays endémiques et à faibles ressources. Un traitement médical seul permet d’éviter les inconvénients de la chirurgie. PMID:25829976

La maladie cœliaque est une entéropathie auto-immune liée à l'intolérance au Gluten qui survient sur un terrain génétiquement prédisposé. Le diagnostic repose sur la combinaison d'arguments cliniques, biologiques et histologiques. Elle est associée à de nombreuses complications, notamment le lymphome. Le risque de tuberculose chez les patients cœliaques est augmenté. Plusieurs hypothèses expliquant cette association ont été discutées. Nous rapportons un cas de maladie cœliaque associée à la tuberculose multifocale chez une patiente âgée de 17 ans. PMID:28979616

The advisory work of the phthisiatrician in an infectious diseases hospital was analyzed; the analysis revealed that in 2005 tuberculose changes of various degrees of activity had been revealed in 42.5% of examined patients, and 32.1% of them were subjects in whom tuberculosis of diferent localizations had been revealed for the first time. In 43.2% of the latter subjects, the reasons for hospitalization were "clinical masks" of tuberculose process (influenza, acute respiratory viral disease), while 48.6% were hospitalized for gastrointestinal infections and viral hepatitis. In 20.7% of cases tuberculosis was combined with HIV infection. In the infectious diseases hospital, 16.2% of patients with active tuberculosis died. Among the patients treated in the infectious diseases hospital during one year, the proportion of patients with active tuberculosis was 1.44%, the proportion of those in whom the process was revealed for the first time, was 0.75%. In Botkin infectious diseases hospital, there were approximately 6% of patients in whom tuberculose process was revealed for the first time in Saint Petersburg. The peculiarities of this group of patients in an infectious diseases hospital require not only tuberculose alertness, but also reinforcement of phthisiatric, radiological, and laboratory services.

To analyze the meanings produced in the Health Surveillance actions for tuberculosis control, carried out by healthcare professionals in Mozambique. Qualitative study using the theoretical and methodological framework of the French Discourse Analysis. A total of 15 healthcare professionals with more than one year of experience in disease control actions participated in the study. Four discursive blocks have emerged from the analysis: tuberculosis diagnosis process; meeting, communication and discussion of treatment; local strategies for tuberculosis control; involvement of family and community leaders in the tuberculosis control. The statements of the healthcare professionals suggest, as Health Surveillance actions, practices that include collecting sputum in the patient's home and sending it to the laboratory; deployment of the medical team with a microscope for tuberculosis testing; and testing for diseases that may be associated with tuberculosis. In this context, the actions of Health Surveillance for tuberculosis control involve valuing all actors: family, community leaders, patients and health professionals. Analisar os sentidos produzidos sobre as ações de Vigilância em Saúde no controle da tuberculose desenvolvidas por profissionais de saúde em Moçambique. Estudo qualitativo que tem como referencial teórico-metodológico a Análise de Discurso de matriz francesa. Participaram do estudo 15 profissionais de saúde, com mais de 1 ano de experiência em ações de controle da doença. Da análise, emergiram quatro blocos discursivos: processo do diagnóstico da tuberculose; reunião, comunicação e discussão do tratamento; estratégias locais para o controle da tuberculose; envolvimento da família e dos líderes comunitários no controle da tuberculose. Os dizeres dos profissionais de saúde sugerem, como ações de Vigilância em Saúde, práticas que incluem a coleta de escarro na residência do paciente e seu encaminhamento ao laboratório; o deslocamento da equipe médica com microscópio para a testagem da tuberculose; e a testagem das doenças que podem estar associadas à tuberculose. Nesse contexto, as ações de Vigilância em Saúde no controle da tuberculose envolvem a valorização de todos os atores: família, líderes comunitários, pacientes e profissionais de saúde.

Introduction La tuberculose ostéoarticulaire (TOA) représente 2 à 5% de l'ensemble des tuberculoses. Elle demeure d'actualité surtout dans les pays à forte endémicité tuberculeuse. L'objectif était de déterminer la prévalence, les aspects topographiques, radiologiques de la TOA en milieu hospitalier ivoirien. Méthodes Les auteurs rapportent une expérience de 11 ans, à travers une étude rétrospective de 120 dossiers de patients atteints de la tuberculose ostéoarticulaire (le mal de Pott est exclu de cette étude). N'ont pas été inclus dans l’étude les dossiers ne comportant pas d'imagerie. Résultats L'atteinte extra vertébrale représentait 09,2% de la tuberculose ostéoarticulaire. Il s'agissait de 54 hommes et 66 femmes, l’âge moyen était de 43,13 ans. On notait 123 cas d'ostéoarthrites, et 8 cas d'ostéites des os plats. L'atteinte des membres inférieurs prédominait dans 91,87% des cas. La hanche était la première localisation (45,04%), suivie du genou (25,19%). Les atteintes étaient multifocales dans 20% des cas. L'atteinte osseuse était associée à une tuberculose pulmonaire dans 05,83% des cas. Des localisations inhabituelles ont été rapportées: poignet (n = 2), branches ischiopubiennes (n = 4), atteinte sternoclaviculaire (n = 4), médiopieds (n = 2). Les lésions radiologiques étaient avancées (stades III et IV) dans 55,73% des cas. A la TDM, la prévalence des abcès était de 77%. Un geste chirurgical a été réalisé sur 16 articulations (2 épaules, 13 genoux, une cheville). Conclusion La TOA des membres est peu fréquente contrairement à l'atteinte vertébrale. La hanche est la principale localisation. Le retard au diagnostic explique l’étendue des lésions anatomoradiologiques. PMID:26587129

Introduction L'objectif de cette étude était de déterminer les facteurs de risque associés à la tuberculose multi résistance à Kinshasa en République Démocratique du Congo. Méthodes Il s'agissait d'une étude cas témoins. Les cas comprenaient tous les patients tuberculeux résistants à la rifampicine et à l'isoniazide notifiés à Kinshasa de janvier 2012 à juin 2013. Les témoins étaient les patients tuberculeux traités durant la même période que les cas et qui à la fin du traitement étaient déclarés guéris. Pour cette étude, nous avons obtenu une clairance éthique. Résultats L’échantillon était constitué de 213 participants dont 132 hommes (62%) et 81 femmes (38%). L’âge médian était de 31ans (16-73 ans). Les facteurs associés significatifs (p< 0,05) à la tuberculose multi résistante étaient le non-respect des heures de prise de médicaments (0R = 111) (80% chez les cas et 4% chez les témoins), l’échec au traitement (0R = 20) (76% chez les cas et 13% chez les témoins); la notion de tuberculose multi résistante dans la famille (0R = 6.4) (28% chez les cas et 6% chez les témoins); la méconnaissance de la tuberculose multi résistante (0R = 3.2) (31% chez les cas et 59% chez les témoins); un séjour en prison (0R = 7.6) (10% chez les cas et 1% chez les témoins) et l'interruption du traitement (0R = 6.1) ( 59% chez les cas et 19% chez les témoins). Conclusion L’émergence de la tuberculose multi résistante peut être évitée par la mise en place des stratégies de diagnostic et de traitement appropriées. PMID:27516818

La Tuberculose constitue un problème de santé publique au Maroc. L’atteinte du système nerveux central est néanmoins rare, survenant dans un contexte de tuberculose multifocale ou miliaire tuberculeuse. Cependant elle peut être un mode de révélation même chez un sujet immunocompétent. Nous rapportons le cas d’un homme de 30 ans qui avait présenté un trouble du langage évoluant dans un contexte d’altération de l’état général avec à l’examen clinique une aphasie motrice de type Broca, un syndrome pyramidal latéralisé à droite et des adénopathies latéro-cérvicales. la sérologie HIV était négative. L’IRM cérébrale: montrait des lésions associant des tuberculomes intracrâniens multiple et une image de méningo-encéphalite. La TDM thoracique montrait de multiples micronodules pulmonaires, une image cavitaire à paroi épaissie et DDB du fowler droit et du culmen. La biopsie des ganglions lymphatiques révélait la présence de granulome typique de tuberculose. Le diagnostic de tuberculose multifocale fut retenu et le patient fut mis sous traitement anti-bacillaire associé à une corticothérapie avec une bonne évolution clinico-radiologique. Cette observation est particulière par l’aspect et le siège des lésions tuberculeuse retrouvées à l’imagerie cérébrale, par l’absence d’immunodéficience, par la bonne évolution sous traitement et souligne l’intérêt de rechercher activement par un bilan exhaustif une infection tuberculeuse extra-cérébrale associée devant toute lésion cérébro-méningée évocatrice de tuberculose.

Le mal de Pott est la forme la plus commune de la tuberculose osseuse touchant essentiellement le rachis dorso-lombaire. La localisation sous-occipitale reste exceptionnelle. Le diagnostic de cette entité est le plus souvent tardif ce qui expose à des complications graves. Les radiographies standard ne sont parlantes qu’à un stade tardif de la maladie, d'où l'intérêt de l'imagerie moderne notamment la tomodensitométrie (TDM) et l'imagerie par résonance magnétique (IRM) qui permettent un diagnostic précoce. Nous rapportons un nouveau cas de tuberculose sous-occipitale. Le diagnostic était posé sur l'imagerie en coupe et confirmé histologiquement à la biopsie transorale. Sont rappelés les aspects en imagerie de cette localisation particulière du mal de Pott. PMID:23819005

The aim of the study was to look back on the course of action involving measures of tuberculosis control in Brazil since the end of the 19th century, covering the history of social struggles and pointing out institutions and people that have dedicated themselves to looking for solutions to these issues. The Brazilian response to tuberculosis started in society with the Ligas Contra a Tuberculose (Leagues Against Tuberculosis), promoting scientific advances, such as the BCG vaccination, which begun in 1927. From the public power, the Inspetoria de Profilaxia da TB (TB Prophylaxis Inspection Service - 1920), the Serviço Nacional de Tuberculose (National Service of Tuberculosis - 1940), and the Campanha Nacional Contra a Tuberculose (National Campaign Against Tuberculosis - 1946), coordinated national policies such as chemotherapy, beginning with the discovery of streptomycin in 1944. The emergence of bacterial resistance led to the development of several therapeutic schemes. The Scheme 1 (rifampycin, hydrazide and pyrazinamid), which was the main one in 1979 and is still used nowadays, had a great epidemiological effect. The WHO declared TB a public health emergency in 1993. In response, Brazil developed some strategies; the first one was the Plano Emergencial para Controle da Tuberculose (Emergency Plan for Tuberculosis Control - 1994), prioritizing 230 municipalities. The current prospects are an effective municipalization of actions and their greater integration with the Programas de Agentes Comunitários e Saúde da Família (Humanitarian Agents and Family Health Programs).

L’objectif de notre étude était de décrire les différents aspects radiographiques de la tuberculose pulmonaire selon le degré de l’immunodépression chez les patients VIH. Nous rapportons une étude rétrospective de 80 patients VIH positif non traités présentant une tuberculose pulmonaire, hospitalisés dans le service de Pneumo-phtisiologie de Brazzaville de Janvier 2013 à Janvier 2014. Notre échantillon était composé de 44 femmes (55%) et 36 hommes (45%) soit un sex ratio de 0,81. La moyenne d’âge était de 37,5±9,17ans, la moyenne du Taux de CD4 était de 153,13±86,6cell/mm3. La microscopie des expectorations à la recherche des bacilles acido-alcoolo-résistants était positive dans 75% des cas chez les patients ayant un taux de lymphocytes T CD4>200cell/ mm3. Les adénopathies médiastinales, les atteintes moyennes, inferieures du champ pulmonaire et la miliaire étaient plus fréquentes chez les patients ayant un taux de lymphocytes T CD4< 200cell/ mm3. L’immunodépression sévère est significativement associée à la présentation radiographique atypique de la tuberculose. PMID:27800112

La maladie de Kaposi (MK) est une entité pathologique qui peut survenir chez les patients VIH positifs et dans le cadre d'une immunodépression, d'origine tuberculeuse très rarement. On décrit le cas d'une MK chez un patient VIH négatif au décours d'une tuberculose. Nous rapportons le cas d'un patient âgé de 81 ans, VIH négatif, ayant présenté deux nodules angiomateux de l'avant bras gauche dont la biopsie cutanée était en faveur d'une MK. L’évolution était marquée 2 mois plus tard, par l'apparition de placards angiomateux extensifs des deux membres supérieurs et d'adénopathies cervicales jugulo-carotidiennes bilatérales. La biopsie ganglionnaire était en faveur d'une tuberculose ganglionnaire. Par ailleurs, il avait un taux sérique élevé des CA 19-9. La régression de l’étendue des lésions au niveau des membres supérieurs et la normalisation du taux sérique des CA 19-9 ont été obtenues sous traitement anti-tuberculeux. Chez les patients atteints d'une MK avec une élévation des CA 19-9, il faut penser à la tuberculose. PMID:24711871

This study aims to analyze the association between the incidence of tuberculosis and different socioeconomic indicators in a territory of intense transformation of the urban space. This is an ecological study, whose analysis units were the neighborhoods of the city of Itaboraí, state of Rio de Janeiro, Brazil. The data have been analyzed by generalized linear models. The response variable was incidence of tuberculosis from 2006 to 2011. The independent variables were the socio-demographic indicators. The spatial distribution of tuberculosis was analyzed with the elaboration of thematic maps. The results have shown a significant association between the incidence of tuberculosis and variables that reflect different dimensions of living conditions, such as consumer goods, housing conditions and its surroundings, agglomeration of population, and income distribution. The disproportionate incidence of tuberculosis in populations with worse living conditions highlights the persistence of socioeconomic determinants in the reproduction of the disease. Different municipal public sectors need to better articulate with local tuberculosis control programs to reduce the social burden of the disease. Analisar a associação entre incidência de tuberculose e diferentes indicadores socioeconômicos em território em intensa transformação do espaço urbano. Estudo ecológico, cujas unidades de análise foram os bairros do município de Itaboraí, RJ. Os dados foram analisados por modelos lineares generalizados. A variável resposta foi incidência de tuberculose de 2006 a 2011. As variáveis independentes foram os indicadores sociodemográficos. A distribuição espacial da tuberculose foi analisada por meio da elaboração de mapas temáticos. Os resultados apontaram associação significativa entre a incidência de tuberculose e variáveis que refletem diferentes dimensões de condições de vida, como bens de consumo, condições de moradia e seu entorno, aglomeração populacional e distribuição de renda. O acometimento desproporcional da tuberculose em grupos populacionais com piores condições de vida ressalta a persistência dos determinantes socioeconômicos na reprodução da doença. Faz-se necessária a melhor articulação de diferentes setores públicos municipais com o programa local de controle da tuberculose visando à redução da carga social da doença.

To analyze the prevalence and factors associated with multidrug-resistant tuberculosis in Espírito Santo, Brazil. This is a cross-sectional study of cases of tuberculosis tested for first-line drugs (isoniazid, rifampicin, pyrazinamide, ethambutol, and streptomycin) in Espírito Santo between 2002 and 2012. We have used laboratory data and registration of cases of tuberculosis - from the Sistema Nacional de Agravos de Notificação and Sistema para Tratamentos Especiais de Tuberculose. Individuals have been classified as resistant and non-resistant and compared in relation to the sociodemographic, clinical, and epidemiological variables. Some variables have been included in a logistic regression model to establish the factors associated with resistance. In the study period, 1,669 individuals underwent anti-tuberculosis drug susceptibility testing. Of these individuals, 10.6% showed resistance to any anti-tuberculosis drug. The rate of multidrug resistance observed, that is, to rifampicin and isoniazid, has been 5%. After multiple analysis, we have identified as independent factors associated with resistant tuberculosis: history of previous treatment of tuberculosis [recurrence (OR = 7.72; 95%CI 4.24-14.05) and re-entry after abandonment (OR = 3.91; 95%CI 1.81-8.43)], smoking (OR = 3.93; 95%CI 1.98-7.79), and positive culture for Mycobacterium tuberculosis at the time of notification of the case (OR = 3.22; 95%CI 1.15-8.99). The partnership between tuberculosis control programs and health teams working in the network of Primary Health Care needs to be strengthened. This would allow the identification and monitoring of individuals with a history of previous treatment of tuberculosis and smoking. Moreover, the expansion of the offer of the culture of tuberculosis and anti-tuberculosis drug susceptibility testing would provide greater diagnostic capacity for the resistant types in Espírito Santo. Analisar a prevalência e fatores associados à tuberculose resistente no Espírito Santo. Estudo transversal dos casos de tuberculose testados para fármacos de primeira linha (isoniazida, rifampicina, pirazinamida, etambutol e estreptomicina) no Espírito Santo entre 2002 e 2012. Foram utilizados dados laboratoriais e de registro de casos de tuberculose - Sistema Nacional de Agravos de Notificação e Sistema para Tratamentos Especiais de Tuberculose. Os indivíduos foram classificados em resistentes e não resistentes, e comparados para variáveis sociodemográficas, clínicas e epidemiológicas. Algumas variáveis foram inclusas em um modelo de regressão logística para estabelecimento de fatores associados à resistência. No período do estudo, 1.669 indivíduos tiveram o teste de sensibilidade aos fármacos antituberculose realizado. Destes, 10,6% apresentaram resistência a qualquer droga antituberculose. A taxa de multirresistência observada, isto é, à rifampicina e isoniazida, foi de 5%. Após a análise múltipla, foram identificados como fatores associados independentes para tuberculose resistente: história de tratamento prévio para tuberculose [Recidiva (OR = 7,72; IC95% 4,24-14,05) e reingresso após abandono (OR = 3,91; IC95% 1,81-8,43)], tabagismo (OR = 3,93; IC95% 1,98-7,79) e cultura positiva para Mycobacterium tuberculosis no momento da notificação do caso (OR = 3,22; IC95% 1,15-8,99). É necessário o fortalecimento da parceria entre os programas de controle de tuberculose e as equipes de saúde que atuam na rede de Atenção Primária à Saúde. Isso possibilitaria identificar e acompanhar indivíduos com história de tratamento prévio para tuberculose e tabagismo. Além disso, a ampliação da oferta de cultura e Teste de Sensibilidade a fármacos antituberculose proporcionaria maior capacidade diagnóstica para as formas resistentes no Espírito Santo.

To assess the degree of implementation of the Directly Observed Treatment, Short-course - DOTS for tuberculosis (TB) in a large city. Assessment of the implementation of the logic model, whose new cases of infectious pulmonary TB were recruited from specialized clinics and followed-up in basic health units. The judgment matrix covering the five components of the DOTS strategy were used. The result of the logic model indicates DOTS was partially implemented. In external, organizational and implementation contexts, the DOTS strategy was partially implemented; and, the effectiveness was not implemented. The partial implementation of the DOTS strategy in the city of Manaus did not reflect in TB control compliance, leading to low effectiveness of the program. Avaliar o grau de implantação da estratégia de tratamento diretamente observado (Directly Observed Treatment, Short-course - DOTS) para tuberculose (TB) em um município de grande porte. Avaliação de implantação por meio de modelo lógico, cujos casos novos de TB pulmonar bacilífera foram recrutados em ambulatórios especializados e acompanhados nas unidades básicas de saúde. Utilizou-se matriz de julgamento que abrange os cinco componentes da estratégia DOTS. O resultado do modelo lógico indica DOTS implantada parcialmente. Nos contextos externo, organizacional e de implantação, a estratégia DOTS está implantada parcialmente; e, na efetividade não está implantada. A implantação parcial da estratégia DOTS, na cidade de Manaus, reflete na não conformidade do controle da TB, levando à baixa efetividade do programa.

La tuberculose pulmonaire est un problème majeur de santé publique. Dans sa forme commune, le diagnostic est habituellement aisé, mais elle peut se présenter sous une forme trompeuse et entrainer un retard diagnostic et thérapeutique. Nous rapportons le cas d’un patient âgé de 25ans, étudiant, sans antécédents pathologiques particuliers, hospitalisé dans notre formation pour un syndrome bronchique trainant avec altération de l’état général. L’examen clinique pleuropulmonaire est normal, l’examen des aires ganglionnaires trouve une adénopathie sus claviculaire droite, la radiographie thoracique de face objective une opacité hilaire droite hétérogène à contours irréguliers, la TDM thoracique retrouve un processus lésionnel tissulaire du lobe supérieur droit qui s’étend vers le médiastin et englobe partiellement la veine cave supérieure avec une adénopathie latérotracheale droite nécrosée. La fibroscopie bronchique objective un élargissement des éperons intersegmentaires du lobe supérieur droit, les biopsies réalisées avec étude histologique sont non concluantes. Les recherches de BK dans les expectorations et dans le liquide d’aspiration bronchique sont negatives. L’IDR à la tuberculine est à 15mm. C’est la ponction transparietale scannoguidée avec étude anatomopathologique qui confirme le diagnostic de tuberculose caseofolliculaire. La sérologie VIH est négative. Le diagnostic de tuberculose pulmonaire pseudotumorale chez un immunocompétent a été retenu et le patient a été mis sous traitement antibacillaire (régime standard national Marocain) par rifampicine, isoniazide, pyrazinamide et éthambutol pendant 6 mois avec évolution clinique et radiologique favorable. La tuberculose pulmonaire ne cesse de tromper le clinicien par son polymorphisme clinique et radiologique, elle doit être évoquée devant toute atteinte pulmonaire d’allure tumorale pour permettre une prise en charge précoce de la maladie.

La tuberculose ganglionnaire (TG) est la localisation extrapulmonaire la plus fréquente au Maroc. Elle pose encore un problème diagnostique et thérapeutique. Le but du travail est d’ étudier le profil épidémiologique, diagnostique et thérapeutique de la tuberculose ganglionnaire. Il s'agit d'une étude rétrospective portant sur les nouveaux cas de TG suivis au centre spécialisé de tuberculose de Marrakech, entre Janvier 2011 et Décembre 2012. Trois cents cinquante sept cas de TG ont été inclus sur l'ensemble de 1717 cas de tuberculose toute forme confondue, soit une incidence de 20,8%. La moyenne d’âge était de 29,1 ans avec un sex ratio de 0,6 (62,5% de femmes). Le diabète, le contage tuberculeux et l'infection VIH ont été retrouvés respectivement dans 9%, 14,6% et 3,6% des cas. Les adénopathies étaient cervicales dans 95%, médiastinales dans 5,1%, abdominales dans 3,7%, axillaires dans 2,8% et inguinales dans 0,3% des cas. La radiographie du thorax (faite dans 96,4% des cas) a été anormale dans 8,1%. Le diagnostic a été confirmé dans 97,2% des cas. Le régime thérapeutique était 2 RHZE/4RH dans 88% des cas. Dans les cas suivis, l’évolution a été marquée par la disparition des adénopathies dans 95,2% et par l'augmentation du volume ganglionnaire dans 4,8%. 1,4% des cas ont été perdus de vue. La rechute de TG a été notée dans 3,1%. La TG reste fréquente et occupe la 2ème place après l'atteinte pulmonaire et pose un problème diagnostique et thérapeutique. PMID:25767675

La localisation cutanée de la maladie tuberculeuse demeure une forme rare et représente seulement 2,1% des localisations. L'objet de cette étude est de rapporter le profil épidémiologique, anatomoclinique et évolutif des cas de tuberculose ganglio-cutanée diagnostiqués dans un CHU au Burkina Faso. La fréquence de la tuberculose cutanée est très faible au CHUSS. Six cas ont été diagnostiqués entre 2004 et 2010, soit une fréquence de un cas par an. La durée d’évolution des cas allait de deux jusqu’à dix ans avant leur diagnostic. Les lésions observées étaient: trois scrofulodermes, trois gommes, une tuberculose testiculaire associée à un mal de Pott, un cas de polyadénopathies et des cicatrices atropho-rétractiles dans la plupart des cas. Sur le plan anatomopathologique, des granulomes tuberculoïdes ont été mis en évidence dans tous les cas avec une forte réaction tuberculinique à l'IDR. Sous antituberculeux pendant six mois, l’évolution a été bonne dans tous les cas mais au prix de séquelles cutanées cicatricielles inesthétiques. Son ampleur reste peut-être encore méconnue. Le renforcement du plateau technique du CHU et une bonne collaboration interdisciplinaire contribuerait à un meilleur diagnostic et prise en charge de cette affection. PMID:24648863

La tuberculose est une maladie infectieuse transmissible provoquée par myco-bacterium tuberculosis (bacille de Koch ou BK). Elle représente, selon les estimations del'Organisation Mondiale de la Santé (OMS), l'une des pathologies infectieuses causant le plus de décès au niveau mondial avec plus de 1 million de décès par an. Pour déterminer les facteurs de risque de mortalité au cours de la tuberculose pulmonaire à microscopie positive nous avons mené une étude rétrospective portant sur tous les cas de tuberculose pulmonaire à microscopie positive et qui étaient décédés au cours de leur hospitalisation. Cette étude a colligé 1803 cas de tuberculose sur une période de 2 ans et demi dont 46 sont décédés. La prévalence de décès est de 2,55%. La population se répartit en 32 hommes et 14 femmes. L’âge moyen était de 53ans ± 17 ans. Le tabagisme était retrouvé chez la moitié des cas. Une comorbidité était retrouvée dans 43%, avec 17% de diabète. Le délai de diagnostic avait une médiane de 60 jours avec percentile (30j; 105j). La symptomatologie clinique était dominée par la toux, la dyspnée et les expectorations soit respectivement: 97,8%, 69,6% et 67,4% des cas. Sur le plan radiologique les lésions étaient diffuses et bilatérales dans 76,1% des cas. Tous les patients étaient mis sous SRHZ. 11% avaient présenté une toxicité aux antibacillaires (de type hépatiques dans 3 cas et neurologiques dans 2 cas). Le délai médian de décès était de 8,5 jours (5j; 17j). Les causes de décès retrouvées étaient: Une hépatite fulminante (3 cas), une décompensation acido-cétosique (3 cas), un SDRA (2 cas), des hémoptysies foudroyantes (2 cas), et respectivement un cas secondaire à une décompensation de BPCO, une décompensation cardiaque, une hypoglycémie et un tableau d'anasarque. Cette étude suggère que le terrain, le retard diagnostique et les effets secondaires du traitement sont les principaux facteurs de risque de mortalité chez les patients hospitalisés pour tuberculose pulmonaire.

To test the association between diabetes and tuberculosis. It is a case-control study, matched by age and sex. We included 323 new cases of tuberculosis with positive results for bacilloscopy. The controls were 323 respiratory symptomatic patients with negative bacilloscopy, from the same health services, such as: ambulatory cases from three referral hospitals and six basic health units responsible for the notifications of new cases of tuberculosis in Salvador, Bahia. Data collection occurred between 2008 and 2010. The instruments used were structured interview, including clinical data, capillary blood glucose (during fasting or postprandial), and the CAGE questionnaire for screening of abusive consumption of alcohol. Descriptive, exploratory, and multivariate analysis was performed using conditional logistic regression. The average age of the cases was 38.5 (SD = 14.2) years and of the controls, 38.5 (SD = 14.3) years. Among cases and controls, most subjects (61%) were male. In univariate analysis we found association between the occurrence of diabetes and tuberculosis (OR = 2.37; 95%CI 1.04-5.42), which remained statistically significant after adjustment for potential confounders (OR = 3.12; 95%CI 1.12-7.94). The association between diabetes and tuberculosis can hinder the control of tuberculosis, contributing to the maintainance of the disease burden. The situation demands increasing early detection of diabetes among people with tuberculosis, in an attempt to improve disease control strategies. Testar a associação entre diabetes e tuberculose. Trata-se de estudo caso-controle, pareado por idade e sexo. Foram incluídos 323 casos novos de tuberculose com resultados positivos à baciloscopia. Os controles foram 323 sintomáticos respiratórios com baciloscopia negativa, oriundos dos mesmos serviços de saúde dos casos: ambulatórios de três hospitais de referência e seis unidades básicas de saúde responsáveis pelas notificações dos casos novos de tuberculose em Salvador, Bahia. A coleta de dados ocorreu entre 2008 e 2010. Os instrumentos utilizados foram entrevista estruturada, incluindo dados clínicos, glicemia capilar (em jejum ou pós-prandial) e o questionário CAGE para triagem de consumo abusivo de álcool. Foi realizada análise descritiva, exploratória e multivariada utilizando-se de regressão logística condicional. A média de idade dos casos foi 38,5 (DP = 14,2) anos e dos controles, 38,5 (DP = 14,3) anos. Tanto entre os casos quanto entre os controles, a maioria (61%) dos indivíduos era do sexo masculino. Na análise univariada, houve associação entre ocorrência de diabetes e de tuberculose (OR = 2,37; IC95% 1,04-5,42), que permaneceu estatisticamente significante após ajuste pelos potenciais confundidores (OR = 3,12; IC95% 1,12-7,94). A associação entre diabetes e tuberculose pode dificultar o controle da tuberculose, contribuindo para manutenção da elevada carga da doença. A situação demanda intensificação da detecção precoce de diabetes entre pessoas com tuberculose, na tentativa de maior efetividade das estratégias de controle da doença.

La tuberculose primitive du nasopharynx est rare, nous présentons deux observations révélées par un aspect pseudo tumoral et à travers lesquelles nous soulevons le problème de diagnostic différentiel avec les lésions malignes du nasopharynx. La première observation concerne un jeune patient de 22 ans hospitalisé pour obstruction nasale bilatérale évoluant dans un contexte d'apyrexie et de conservation de l’état général. La nasofibrosopie et le scanner ont monté un processus tumoral évoquant une hypertrophie des végétations adénoïdes. Le deuxième cas est celui d'un homme de 45 ans tabagique chronique qui a présenté une adénopathie latérocervicale droite, une obstruction nasale et une otite séromuqueuse homolatérale. La nasophibroscopie et le scanner on montré un bourgeon tumoral postéro latéral droit du nasopharynx évoquant un carcinome nasopharyngé. Les biopsies du nasopharynx et les études histologiques, chez les deux patients, ont confirmé le diagnostic de tuberculose. La recherche d'autres localisations était négative. Le pronostic était favorable après 6 mois de traitement antibacillaire. La tuberculose primitive du cavum est rare, elle revêt le plus souvent des formes pseudotumorales et pose des problèmes de diagnostic différentiel avec les tumeurs nasopharyngées, son pronostic sous traitement antibacillaire est.

Ce cas clinique rapporte un cas de tuberculose hépatique de présentation échographique exceptionnelle. Nous avons réalisé l’échographie abdominale d'un adolescent de 12 ans, immuno-compétent, sans notion de contage tuberculeux, se plaignant de douleur abdominale chronique évoluant depuis 8 mois associée à des signes frustres d‘imprégnation tuberculeuse. L'examen échographique a été réalisé à l'aide d'un appareil écho-doppler de marque Logic 400 de la firme General Electric. L’échographie abdominale a mis en évidence, une hépatomégalie comportant de multiples micro-abcès hypoéchogènes homogènes, mesurant entre 3 et 4 mm de diamètre et disséminés dans tout le parenchyme hépatique donnant l'aspect de miliaire. Une ascite de moyenne abondance localisée dans le pelvis a été objectivée. Il n'y avait pas d'adénopathies profondes ni de nodules péritonéaux. La ponction biopsie hépatique sous guidage échographique a permis de faire le diagnostic de tuberculose hépatique à l'histologie et à la bactériologie. Le patient a été mis sous traitement spécifique avec une surveillance échographique mensuelle. La disparition des micro-abcès et le tarissement de l'ascite ont été obtenus au bout du 4ème mois du traitement. Celle de l'hépatomégalie est survenue un mois plus tard. L’échographie joue un rôle très important dans la détection précoce de la tuberculose hépatique, son diagnostic précis et la surveillance du traitement. Lors de sa réalisation dans un contexte de douleur abdominale chronique chez l'enfant, l’échographiste devrait évoquer le diagnostic de tuberculose hépatique devant une hépatomégalie multi-micro-abcédée, même chez l'enfant immuno-compétent.

To analyze the care provided to tuberculosis cases in primary health care services according to the elements of the Chronic Care Model. Cross-sectional study conducted in a capital city of the northeastern region of Brazil involving 83 Family Health Strategy professionals.A structured tool adapted to tuberculosis-related care in Brazil was applied.Analysis was based on the development of indicators with capacity to produce care varying between limited and optimum. The organization of care for tuberculosis and supported self-care presented reasonable capacity.In the coordination with the community, the presence of the community agent presented optimum capacity.Partnership with organizations of the community and involvement of experts presented limited capacity.The qualification of professionals, the system for scheduling and monitoring tuberculosis in the community, and the clinical information system presented basic capacity. The capacity of the primary health care services to produce tuberculosis-related care according to the elements of the Chronic Care Model is still limited.Overcoming the fragmentation of care and prioritizing a systemic operation between actions and services of the health care network remains as a major challenge.

The Stop TB Partnership has engaged the 22 high-burden countries in a drive toward the goal of finding 70% of cases and curing 85% by 2005. Traditional partners, aid agencies and governments of industrialised nations have joined the Partnership, but the broader range of civil society remains outside the discourse, risking disinterest on the part of the donor community. Stop TB-Halte à la Tuberculose-Canada was organised to engage new partners to support the Canadian government's commitment to the goal of reducing poverty and diseases of poverty, including tuberculosis, by 50% by 2010. The successes and challenges are explored, and the possibility raised that having a Stop TB movement in every country will ensure that support is sustained and goals of global tuberculosis control reached.

Les perforations de la cloison nasale constituent une pathologie fréquente en ORL. Leurs causes sont multiples et restent dominées par les traumatismes chirurgicaux. Les étiologies infectieuses et notamment la tuberculose sont rares. Nous présentons le cas d'une patiente ayant bénéficié d'une méatotomie bilatérale et chez laquelle une perforation de la cloison nasale a été découverte lors d'un examen systématique à un an de son intervention. D'abord considérée comme une complication de la chirurgie, la biopsie des berges de la perforation a permis de déterminer son origine tuberculeuse. La présentation clinique des perforations de la cloison nasale n'est pas spécifique. Elles sont souvent asymptomatiques et de découverte fortuite. Les traumatismes notamment chirurgicaux sont le plus siuvent en cause. L′orogine tuberculeuse resta très rare. Le diagnostic de certitude de tuberculose repose sur la biopsie des berges de cette perforation. Le but de ce travail est de mettre en avant l'intérêt de la biopsie dans le diagnostic de la tuberculose de la cloison nasale. Cette biopsie doit être systématique même en cas d'antécédents de chirurgie endonasale qui est le plus souvent en cause dans les perforations de la cloison nasale. PMID:24932334

Cinq observations sont colligées dans le service de chirurgie générale de l’hôpital militaire Avicenne de Marrakech au cours de l’année 2007. Les aspects cliniques sont disparates. Ainsi, les auteurs ont noté un syndrome péritonéal dans un cas, une masse épigastrique dans un cas, une lésion suspect du sigmoïde dans un cas, une masse de la fosse iliaque droite dans un cas et une altération de l’état général avec fièvre dans le dernier cas. Un seul patient avaient bénéficié d’une biopsie scano-guidée et les quatre patients restants avaient été opérés. Une masse du méso côlon était notée dans le premier cas. Dans le second cas, l’aspect de la masse épigastrique et son siège avaient orienté vers une tumeur du grand omentum. Une localisation tuberculeuse péritonéale et sigmoïdienne avait été trouvée dans le troisième cas. Le diagnostic d’une tumeur du côlon droit était hautement suspect chez le patient séropositif qui avait présenté une péritonite post-opératoire et décédé à J + 3 dans un tableau de choc septique. Le siège et l’aspect nécrotique des lésions trouvées à la tomodensitométrie chez la seule patiente de l’étude avaient fait discuter en premier un lymphome. Même en l’absence d’antécédents de tuberculose pulmonaire, le diagnostic tuberculose abdominale pseudo-tumorale doit être évoqué surtout dans un pays d’endémie comme le notre et le recours à une laparotomie est justifié chaque fois que persiste un doute diagnostique ou en cas de complication.

Introduction Le défi des pays en voie de développement est la disponibilité de méthodes de diagnostic rapide et précis pour le management de la tuberculose. Des techniques moléculaires offrent cet avantage et nous avons utilisé le test GeneXpert MTB/RIF dans le diagnostic de la tuberculose extra-pulmonaire pour évaluer sa performance par rapport aux méthodes conventionnelles. Méthodes Entre 2010 et 2015, 544 échantillons cliniques extra-pulmonaires ont été recueillis et traitées par la microscopie, la culture et le GeneXpert. L'étude de la sensibilité aux antituberculeux a été effectué avec le MGIT 960. Le Génotype MTBDRplus a été utilisé pour confirmer les cas de résistance à la rifampicine détectés par le système GX. Résultats La population d'étude de 544 patients incluait 55,15% d'hommes et 44,85% de femmes. L'âge des patients variait entre 1 à 92 avec la majorité dans le groupe d'âge 18-45 ans. La sensibilité et la spécificité globale de la microscopie étaient de 43,86% et 98,36%, et pour le GeneXpert® 94,74% et 97,95% respectivement avec 95% IC. Deux résultats de résistance à la rifampicine discordants ont été trouvées entre le test GeneXpert et la méthode phénotypique. Les résultats du test MTBDRplus ont montré une concordance de 100% avec ceux du MGIT 960 pour les cas discordants de résistance à la rifampicine. Conclusion Cette étude a montré que le test GeneXpert a une plus grande sensibilité pour le diagnostic de routine de la tuberculose extra-pulmonaire et devrait être utilisé à la place de la microscopie. Les cas de résistance à la rifampicine détectés par le GeneXpert doivent être confirmés par d'autres tests moléculaires avant d'initier un traitement. PMID:28292091

La tuberculose pelvienne pseudo tumorale est une maladie infectieuse curable. Son tableau clinique est souvent trompeur simulant une tumeur ovarienne ou tubaire. Le but de notre travail est de préciser les caractéristiques cliniques, biologiques et radiologiques de cette pathologie et sa prise en charge. Nous rapportons une étude rétrospective à propos de quatre observations. L’âge moyen de nos patientes est de 24 ans (16 ans, 40 ans), trois parmi elles étaient célibataires. Le motif de consultation est dominé par les douleurs abdominopelviennes chroniques. Les résultats des explorations radiologiques (échographie pelvienne associé à la TDM ou IRM pelvienne) ont été en faveur d'une tumeur ovarienne dans trois cas et d'un hydrosapinx bilatéral pour un cas. L'ascite a été présente dans tous les cas. Le dosage de la Ca 125 a été élevé. La prise en charge a été l'exploration chirurgicale soit par c'lioscopie ou laparotomie. Deux cas ont bénéficié seulement des biopsies et deux patientes ont eu une salpingectomie bilatérale devant l'aspect pseudo tumoral très suspect. L’étude histologique a confirmé des lésions graulomateuses avec nécrose caséeuse. Le traitement par les antibacillaires a été instauré selon le protocole 2ERHZ/ 4RH. La tuberculose pelvienne pseudo tumorale est l'apanage de la femme jeune. Son pronostic est lié à l'infertilité séquellaire. PMID:23330043

Le puisatier a pour profession le creusement et l'entretien des puits pour fournir de l'eau. Il est au contact de divers minerais, particulièrement la silice, particule qui présente un risque certain de développement des maladies pulmonaires connues sous le nom de silicose. Le but de notre travail est de préciser le profil épidémiologique, clinique, radiologique et évolutif des patients puisatiers silicotiques. C'est une étude rétrospective concernant 54 cas de puisatiers ayant une silicose, colligés au service des maladies respiratoires du CHU Ibn Rochd de Casablanca, de Mars 1997 à Janvier 2016. Tous les malades étaient des puisatiers, de sexe masculin, avec une moyenne d'âge de 50 ans. Le tabagisme était retrouvé dans 36 cas et un antécédent de tuberculose était noté dans huit cas. La radiographie thoracique retrouvait des grandes opacités dans 39 cas, des petites opacités dans 15 cas, et un épaississement des septats dans 11 cas. Ce tableau de silicose s'était compliqué d'une surinfection bactérienne dans 37% des cas, d' un pneumothorax dans 4% des cas et d'une tuberculose dans 20% des cas. La prise en charge thérapeutique était celle des complications. La déclaration de la maladie professionnelle et de l'indemnisation était faite. L'évolution était bonne dans 12 cas, stationnaire dans 17 cas et mauvaise dans 16 cas. La silicose est une pneumoconiose fréquente chez les puisatiers. Elle retentit sur la fonction respiratoire. Nous soulignons l'association fréquente de tuberculose et nous insistons sur la prévention qui reste le meilleur traitement. PMID:28292119

We conducted a cross-sectional, retrospective study, characterized by classical and molecular epidemiology, involving M. tuberculosis isolates from a regional prison in southern Brazil. Between January of 2011 and August of 2014, 379 prisoners underwent sputum smear microscopy and culture; 53 (13.9%) were diagnosed with active tuberculosis. Of those, 8 (22.9%) presented with isoniazid-resistant tuberculosis. Strain genotyping was carried out by 15-locus mycobacterial interspersed repetitive unit-variable-number tandem-repeat analysis; 68.6% of the patients were distributed into five clusters, and 87.5% of the resistant cases were in the same cluster. The frequency of drug-resistant tuberculosis cases and the rate of recent transmission were high. Our data suggest the need to implement an effective tuberculosis control program within the prison system. RESUMO Estudo transversal, retrospectivo, com isolados de M. tuberculosis de pacientes de um presídio regional no sul do Brasil, caracterizado através de epidemiologia clássica e molecular. Entre janeiro de 2011 e agosto de 2014, 379 detentos foram submetidos a baciloscopia e cultura, sendo 53 (13,9%) diagnosticados com tuberculose ativa. Desses, 8 (22,9%) apresentavam tuberculose resistente a isoniazida. A genotipagem das cepas foi realizada por 15-locus mycobacterial interspersed repetitive units-variable number of tandem repeat analysis; 68,6% dos pacientes estavam distribuídos em cinco clusters, e 87,5% dos casos resistentes estavam em um mesmo cluster. Verificou-se uma frequência elevada de casos de resistência e alta taxa de transmissão recente. Estes dados sugerem a necessidade da implantação de um programa efetivo de controle da tuberculose no sistema prisional.

Nous rapportons le cas d'un enfant de 7 ans, de sexe masculin ayant présenté un purpura thrombopénique avec épistaxis, hématémèse, otorragies et pétéchies généralisées. Durant la même hospitalisation, nous avons mis en évidence une tuberculose pulmonaire documentée par la présence de bacilles acido-alcoolo résistants à l'examen des crachats. Nous avons observé une majoration du taux de plaquettes en une semaine de corticothérapie intraveineuse à haute dose, avant l'instauration d'une poly chimiothérapie antituberculeuse. Nous rappelons également la controverse que suscite la prise en charge de cette association rarement rapportée. PMID:23077696

La nocardiose est une infection rare, mais sévère, causée par des bactéries du genre nocardia, qui appartiennent à l'ordre des actinomycétales. Si elles peuvent toucher l'adulte immunocompétent, les nocardioses restent des pathologies de l'individu fragilisé sur le plan immunitaire. L'atteinte pulmonaire reste la plus fréquente, sa prise en charge correcte est liée au diagnostic qui est souvent retardé par des présentations non spécifiques et des prélèvements non concluants. Nous rapportons ici deux cas de nocardiose chez des patients immunocompétents. Le premier cas est celui d'un homme de 24 ans, avec notion de tabagisme et d'éthylisme, hospitalisé pour des douleurs thoraciques et des hémoptysies de faible abondance, évoluant depuis deux mois, avec apparition d'abcès sous cutanés dorsaux fistulisés. L'exploration radiologique découvre une masse tissulaire médiastino-pulmonaire droite avec lyse costale adjacente et diffusion aux tissus para vertébraux droits. Les prélèvements bactériologiques restent négatifs motivant une biopsie scannoguidée de la lésion qui est revenue en faveur d'infection à nocardiose. Le second cas concerne un homme de 22 ans, aux antécédents de tuberculose pleurale traitée il y a 8 ans puis une rechute de tuberculose en 2011 (abcès médiastinal). Admis pour suspicion de rechute de tuberculose devant une toux chronique avec altération de l'état général et une hépatosplénomégalie. Le scanner thoracique montre des condensations alvéolaires avec pleurésie. Au cours de son hospitalisation, apparition de tuméfactions sous cutanées purulentes dont l'étude bactériologique du pus est revenue en faveur de nocardiose avec une souche résistante à tous les antibiotiques sauf colistine et bactrim. Les auteurs illustrent à travers ces deux observations, les aspects cliniques et radiologiques de nocardiose pulmonaire en mettant le point sur les difficultés diagnostiques et thérapeutiques surtout dans un pays à forte prévalence de tuberculose et très faible incidence de nocardiose.

Pleuroparenchymal fibroelastosis (PPFE) is a rare lung disease. It can be idiopathic or associated with any one of various conditions. To our knowledge, this is the first report of two cases of PPFE in Brazil. Our first patient presented with pleural and subpleural fibrosis in the upper lobes; a spiculated nodule in the left upper lobe; and a mild reticular pattern in the lower lobes. Surgical lung biopsy revealed PPFE in the upper lobes, including the nodule, and unclassified interstitial pneumonia in the left lower lobe. Our second patient had a history of exposure to domestic birds, indicating a risk of hypersensitivity pneumonitis, and presented with advanced lung disease, predominantly in the upper lobes, together with subpleural fibrosis.That patient underwent lung transplantation. In the explant specimen, PPFE and granulomas were identified, suggesting hypersensitivity pneumonitis as an associated cause. RESUMO A fibroelastose pleuroparenquimatosa (FEPP) é uma doença pulmonar rara, podendo ser idiopática ou associada a diversas condições. Pelo que sabemos, este é o primeiro relato de dois casos de FEPP no Brasil. Nosso primeiro paciente apresentava fibrose pleural e subpleural nos lobos superiores, um nódulo espiculado no lobo superior esquerdo e um padrão reticular discreto nos lobos inferiores. A biópsia pulmonar cirúrgica demonstrou FEPP nos lobos superiores, incluindo no nódulo, e pneumonia intersticial não classificada no lobo inferior esquerdo. Nosso segundo paciente tinha história de exposição a aves domésticas, indicando um risco de pneumonite de hipersensibilidade, e doença pulmonar avançada predominando em lobos superiores, com fibrose subpleural. Esse paciente foi submetido a transplante pulmonar. No espécime do explante, FEPP e granulomas foram identificados, sugerindo pneumonite de hipersensibilidade como causa associada.

Les douleurs lombaires relèvent d'étiologies multiples dont le diagnostic peut être source de grandes difficultés. Le lymphome rachidien primitif est rare et son diagnostic nécessite une biopsie souvent scanoguidée. Un homme de 30 ans, était hospitalisé pour lombalgies inflammatoires évoluant dans un contexte d'altération de l'état général avec à l'examen des douleurs à la palpation des apophyses épineux L2L3, sans syndrome tumoral périphérique. Le bilan biologique montrait un syndrome inflammatoire. Le bilan morphologique était en faveur d'une spondylodiscite. La première biopsie montrait une ostéite granulomateuse. L'aggravation clinique et radiologique sous anti bacillaire a mené à reconsidérer le diagnostic et la deuxième biopsie confirme le diagnostic du lymphome. Le diagnostic de tuberculose osseuse en particulier vertébrale nécessite une confirmation bactériologique et ou histologique pour ne pas méconnaître un lymphome osseux primitif. PMID:28292061

The objective of this study is to evaluate the performance of the Tuberculosis Control Program in municipalities of the State of São Paulo. This is a program evaluation research, with ecological design, which uses three non-hierarchical groups of the municipalities of the State of São Paulo according to their performance in relation to operational indicators. We have selected 195 municipalities with at least five new cases of tuberculosis notified in the Notification System of the State of São Paulo and with 20,000 inhabitants or more in 2010. The multiple correspondence analysis was used to identify the association between the groups of different performances, the epidemiological and demographic characteristics, and the characteristics of the health systems of the municipalities. The group with the worst performance showed the highest rates of abandonment (average [avg] = 10.4, standard deviation [sd] = 9.4) and the lowest rates of supervision of Directly Observed Treatment (avg = 6.1, sd = 12.9), and it was associated with low incidence of tuberculosis, high tuberculosis and HIV, small population, high coverage of the Family Health Strategy/Program of Community Health Agents, and being located on the countryside. The group with the best performance presented the highest cure rate (avg = 83.7, sd = 10.5) and the highest rate of cases in Directly Observed Treatment (avg = 83.0, sd = 12.7); the group of regular performance showed regular results for outcome (avg cure = 79.8, sd = 13.2; abandonment avg = 9.5, sd = 8.3) and supervision of the Directly Observed Treatment (avg = 42.8, sd = 18.8). Large population, low coverage of the Family Health Strategy/Program of Community Health Agents, high incidence of tuberculosis and AIDS, and being located on the coast and in metropolitan areas were associated with these groups. The findings highlight the importance of the Directly Observed Treatment in relation to the outcome for treatment and raise reflections on the structural and managerial capacity of municipalities in the implementation of the Tuberculosis Control Program. Avaliar o desempenho do Programa de Controle da Tuberculose em municípios paulistas. Pesquisa de avaliação de serviços, com delineamento ecológico, utilizando três agrupamentos não hierárquicos de municípios paulistas de acordo com seu desempenho em relação a indicadores operacionais. Foram selecionadas 195 cidades com no mínimo cinco casos novos de tuberculose notificados no Sistema de Notificação do Estado de São Paulo e 20.000 habitantes ou mais em 2010. A análise de correspondência múltipla foi utilizada para a identificação da associação entre os grupos de distintos desempenhos e as características epidemiológicas, demográficas e de sistemas de saúde dos municípios. O grupo de pior desempenho apresentou as taxas mais elevadas de abandono (média [md] = 10,4; desvio padrão [dp] = 9,4) e as menores proporções de efetivação de Tratamento Diretamente Observado (md = 6,1; dp = 12,9) e esteve associado à baixa incidência de tuberculose, alta confecção tuberculose e HIV, pequeno porte populacional, alta cobertura de Estratégia Saúde da Família/Programa de Agentes Comunitários em Saúde e localização no interior. O grupo de melhor desempenho apresentou a maior taxa de cura (md = 83,7; dp = 10,5) e a maior proporção de casos em Tratamento Diretamente Observado (md = 83,0; dp = 12,7); enquanto o grupo de desempenho regular mostrou resultados regulares de desfecho (cura: md = 79,8; dp = 13,2; abandono: md = 9,5; dp = 8,3) e de efetivação do Tratamento Diretamente Observado (md = 42,8; dp = 18,8). Grande porte populacional, baixa cobertura de Estratégia Saúde da Família/Programa de Agentes Comunitários em Saúde, alta incidência de tuberculose e aids, e localização no litoral e em áreas metropolitanas estiveram associados com esses grupos. Os achados destacam a importância do Tratamento Diretamente Observado em relação ao desfecho do tratamento e levantam reflexões sobre a capacidade estrutural e gerencial dos municípios na operacionalização do Programa de Controle da Tuberculose.

Pulmonary involvement in systemic sclerosis. Alveolitis, fibrosis and pulmonar arterial hypertension Lung disease is present in most of the patients with systemic sclerosis and is now the most important cause of mortality. Interstitial lung disease and pulmonary hypertension are, so far, the main disorders found and both are difficult to detect at the earliest stages. However, diagnostic tools such as immunological test, lung function test, high resolution CT, bronchoalveolar lavage, echocardiography, right-side cardiac catheterization, or lung biopsy are necessary to accurately evaluate the clinical status and allow to improve the management organ-specific ad hoc. Progress in immunological and vascular therapies as well as other emergence drugs offer new expectations to scleroderma patients. Copyright © 2006 Elsevier España S.L. Barcelona.

To describe our experience with video-assisted thoracic surgery (VATS) for anatomic pulmonary resection at a referral center for thoracic surgery in Brazil. All patients who underwent anatomic pulmonary resection by VATS between 2010 and 2015 were included. Clinical and pathological data, as well as postoperative complications, were analyzed. A total of 117 pulmonary resections by VATS were performed, of which 98 were lobectomies and 19 were anatomic segmentectomies. The mean age of the patients was 63.6 years (range, 15-86 years). Females predominated (n = 69; 59%). The mean time to chest tube removal was 2.47 days, and the mean length of ICU stay was 1.88 days. The mean length of hospital stay was 4.48 days. Bleeding ≥ 400 mL occurred in 15 patients. Conversion to thoracotomy was required in 4 patients. Our results are similar to those published in major international studies, indicating that VATS is an important strategy for pulmonary resection. They also show that VATS can be safely performed with adequate training. This technique should be used more often for the treatment of lung diseases in Brazil. Relatar a experiência com cirurgia torácica videoassistida (CTVA) para ressecções pulmonares anatômicas em um centro nacional de referência de cirurgia torácica no Brasil. Foram incluídos todos os pacientes tratados com ressecções pulmonares anatômicas por CTVA entre 2010 e 2015 e analisados dados clínicos e patológicos, assim como complicações pós-operatórias. Foram realizadas 117 ressecções pulmonares por CTVA, sendo 98 lobectomias e 19 segmentectomias anatômicas. A média de idade foi de 63,6 anos (variação, 15-86 anos), sendo a maioria mulheres (n = 69; 59%). A média de tempo de permanência com dreno foi de 2,47 dias e a de estada em UTI foi de 1,88 dias. A média de tempo de internação foi de 4,48 dias. Sangramento ≥ 400 ml ocorreu em 15 pacientes. Houve conversão para toracotomia em 4 pacientes. Nossos resultados vão ao encontro de publicações em grandes séries internacionais, corroborando que a CTVA é uma importante via de execução de ressecções pulmonares e que pode ser realizada com segurança quando há treinamento adequado, devendo ser mais utilizada no Brasil para o tratamento das doenças pulmonares.

Resumo Contexto Devido à maior aplicação de exames de imagem rotineiros, especialmente nos pacientes com neoplasia para controle da doença, vem aumentando o diagnóstico de tromboembolismo pulmonar (TEP) incidental, importante fator de morbimortalidade associado. Objetivo Identificar os casos de TEP incidental em pacientes oncológicos submetidos a tomografia computadorizada (TC) de tórax, correlacionando aspectos clínicos e fatores de risco associados. Métodos Estudo retrospectivo de todos os episódios de TEP ocorridos de janeiro de 2013 a junho de 2016, com seleção dos pacientes oncológicos e divisão deles em dois grupos: com suspeita clínica e sem suspeita clínica (incidentais) de embolia pulmonar. Resultados Foram avaliados 468 pacientes com TEP no período citado. Destes, 23,1% eram oncológicos, entre os quais 44,4% apresentaram achado incidental de embolia pulmonar na TC de tórax. Não houve diferença estatística entre os grupos para sexo, idade e tabagismo. Quanto à procedência, 58,3% dos pacientes sem suspeita clínica eram de origem ambulatorial e 41,7% com suspeita de TEP vinham do pronto-socorro (p < 0,001). As neoplasias mais prevalentes foram de pulmão (17,6%), intestino (15,7%) e mama (13,0%). Aqueles com achado incidental apresentaram significativamente mais metástases, sem diferença entre os grupos para realização de quimioterapia, radioterapia ou cirurgia recente. Quanto aos sintomas apresentados, 41,9% daqueles sem suspeita clínica tinham queixas sugestivas de TEP quando realizaram o exame. Conclusão TEP incidental é frequente em pacientes oncológicos, especialmente naqueles provenientes de seguimento ambulatorial e em estágios avançados da doença. Sintomas sugestivos de TEP estavam presentes em pacientes sem suspeita clínica ao realizarem a TC de tórax. PMID:29930652

To determine the prevalence of and the factors associated with latent Mycobacterium tuberculosis infection (LTBI) in prisoners in the state of Minas Gerais, Brazil. This was a cross-sectional cohort study conducted in two prisons in Minas Gerais. Tuberculin skin tests were performed in the individuals who agreed to participate in the study. A total of 1,120 individuals were selected for inclusion in this study. The prevalence of LTBI was 25.2%. In the multivariate analysis, LTBI was associated with self-reported contact with active tuberculosis patients within prisons (adjusted OR = 1.51; 95% CI: 1.05-2.18) and use of inhaled drugs (adjusted OR = 1.48; 95% CI: 1.03-2.13). Respiratory symptoms were identified in 131 (11.7%) of the participants. Serological testing for HIV was performed in 940 (83.9%) of the participants, and the result was positive in 5 (0.5%). Two cases of active tuberculosis were identified during the study period. Within the prisons under study, the prevalence of LTBI was high. In addition, LTBI was associated with self-reported contact with active tuberculosis patients and with the use of inhaled drugs. Our findings demonstrate that it is necessary to improve the conditions in prisons, as well as to introduce strategies, such as chest X-ray screening, in order to detect tuberculosis cases and, consequently, reduce M. tuberculosis infection within the prison system. Determinar a prevalência e os fatores associados à infecção latente por Mycobacterium tuberculosis (ILTB) em pessoas privadas de liberdade no Estado de Minas Gerais. Estudo de coorte transversal realizado em duas penitenciárias em Minas Gerais. Foi realizada a prova tuberculínica nos indivíduos que aceitaram participar do estudo. Foram selecionados 1.120 indivíduos para a pesquisa. A prevalência da ILTB foi de 25,2%. Na análise multivariada, a ILTB esteve associada com relato de contato com caso de tuberculose ativa dentro da penitenciária (OR ajustada = 1,51; IC95%: 1,05-2,18) e uso de drogas inaláveis (OR ajustada = 1,48; IC95%: 1,03-2,13). Foram identificados 131 pacientes sintomáticos respiratórios (11,7%). O teste anti-HIV foi realizado em 940 (83,9%) dos participantes, sendo positivo em 5 indivíduos (0,5%). Dois casos de tuberculose ativa foram identificados no período do estudo. A prevalência de ILTB dentro das penitenciárias estudadas foi alta. Além disso, a ILTB estava associada ao relato de contato com casos de tuberculose e ao uso de drogas inaláveis. Nossos achados demonstram que é necessária a melhoria das condições de encarceramento e a utilização de outras estratégias, como a triagem por radiografia de tórax, para a descoberta de casos de tuberculose e redução da infecção pelo M. tuberculosis no sistema penitenciário.

Successful surgical correction of (la estenosis pulmonar en la tetralogía de Fallot), requires that the postoperative ratio between the (right ventricular pressure) and (left ventricular pressure) (PVD/PVI) be less than 0.70. By measuring the ring diameter and pulmonary branch on relation to the (superficie corporal) it is possible to predict the outcome of this ratio and therefore indicate whether or not it is necessary to increase (AP). This paper presents our experience with 24 patients subjected to total correction of (tetralogía de Fallot) from March of 1975 to the present using the above criteria. The average age was 7 years (ranging from 2 to 20). In all cases the (cresta supraventricular) was (resected). In 14 (58%) a (valvultomia pulmonar) was performed and in 9 patients (37) it was necessary to increase the ring and pulmonary branch of the pulmonary artery according to measurements taken. The post-operative relationship PVD/PVI was 0.2-0.3: 15%, 0.4-0.5: 60%, 0.6-0.7: 25% In no case was the ratio greater than 0.70. No significant difference was found between those cases requiring... (parche transanular) and those where such treatment was not necessary. Three patients (12%) died immediately following the operation. It is concluded that measurement of the diameter of the pulmonary ring in comparison to the (superficie corporal) is extremely useful in management during surgery of (estenosis pulmonar) in patients with (tetralogía de Fallot).

Resumo O tromboembolismo pulmonar permanece como um grande desafio terapêutico para os médicos especialistas, pois, apesar de todo investimento e desenvolvimento em seu diagnóstico, profilaxia e tratamento, essa condição continua sendo a principal causa de morte evitável em ambiente hospitalar. Ainda restam muitas dúvidas em relação a qual perfil de paciente vai se beneficiar de fato da terapia fibrinolítica sistêmica, sem ficar exposto a um grande risco de sangramento. A estratificação de risco e a avaliação do prognóstico do evento, através de escores clínicos de insuficiência ventricular direita, marcadores de dilatação e disfunção do ventrículo direito e avaliação da massa trombótica, associados ou de forma isolada, são ferramentas que podem auxiliar na identificação do paciente que irá se beneficiar dessa terapia. Os únicos consensos em relação à terapia fibrinolítica no tratamento do tromboembolismo pulmonar são: não deve ser indicada de forma rotineira; nenhum dos escores ou marcadores, isoladamente, devem justificar seu uso; e os pacientes com instabilidade hemodinâmica são os mais beneficiados. Além disto, deve-se avaliar cada caso em relação ao risco de sangramento, especialmente no sistema nervoso central. PMID:29930636

to analyze the feasibility of quality indicators for evaluation of hospital programs for preventing occupational tuberculosis. a descriptive cross-sectional study. We tested indicators for evaluating occupational tuberculosis prevention programs in six hospitals. The criterion to define feasibility was the time spent to calculate the indicators. time spent to evaluate the indicators ranged from 2h 52min to 15h11min 24sec. The indicator for structure evaluation required less time; the longest time was spent on process indicators, including the observation of healthcare workers' practices in relation to the use of N95 masks. There was an hindrance to test one of the indicators for tuberculosis outcomes in five situations, due to the lack of use of tuberculin skin test in these facilities. The time requires to calculate indicators in regarding to the outcomes for occupational tuberculosis largely depends upon the level of organizational administrative structure for gathering data. indicators to evaluate the structure for occupational tuberculosis prevention are highly feasible. Nevertheless, the feasibility of indicators for process and outcome is limited due to relevant variations in administrative issues at healthcare facilities. analisar a viabilidade de indicadores de qualidade para avaliação de programas hospitalares de prevenção de tuberculose ocupacional. estudo descritivo transversal.

La tuberculose est un véritable problème de santé publique. C'est une maladie guérissable et cette guérison passe par une bonne prise en charge thérapeutique. Il arrive parfois on assiste à l’échec thérapeutique, d'où l'intérêt de notre étude portant sur les facteurs prédictifs de ses échecs. Dans l'espace d'une année sur 1300 cas de tuberculose toute forme confondue, 700 cas de tuberculose pulmonaire à microscopie positive ont été répertorié dont 100 cas transférés. La tranche d’âge de 15-25 ans a été la plus touchée avec un sexe-ratio de 2 en faveur des hommes et 41,66% de nos malades ont été les ouvriers suivis de 20,83% des commerçants. La majorité de nos patients provenait de Conakry soit 99, 5%. Sur 600 patients suivis les nouveaux cas représentaient 83,33% et l’échec thérapeutique représentait 12 cas soit 2%. L'interruption du traitement représente le principal facteur de l’échec. Les facteurs qui ont influencé la régularité des malades au traitement ont été multiples. Des facteurs liés à l'organisation du système de santé, la rupture des médicaments antituberculeux, l’éducation sanitaire insuffisante, les contraintes de la supervision du traitement, l'implication insuffisante et la vente des médicaments par le personnel de santé. Des facteurs liés aux patients eux-mêmes, la crainte de perte d'emploi, les contraintes financières. Les renforcements de l'organisation du système sanitaire et l’éducation thérapeutiques pourront réduire le taux d’échec du traitement antituberculeux. L'amélioration de la qualité de la prise en charge des malades en situation d’échec devrait passer par une culture systématique des expectorations avec antibiogramme. PMID:26889327

To evaluate pulmonary function and functional capacity in children and adolescents with sickle cell disease. This was a cross-sectional study involving 70 children and adolescents (8-15 years of age) with sickle cell disease who underwent pulmonary function tests (spirometry) and functional capacity testing (six-minute walk test). The results of the pulmonary function tests were compared with variables related to the severity of sickle cell disease and history of asthma and of acute chest syndrome. Of the 64 patients who underwent spirometry, 15 (23.4%) showed abnormal results: restrictive lung disease, in 8 (12.5%); and obstructive lung disease, in 7 (10.9%). Of the 69 patients who underwent the six-minute walk test, 18 (26.1%) showed abnormal results regarding the six-minute walk distance as a percentage of the predicted value for age, and there was a ≥ 3% decrease in SpO2 in 36 patients (52.2%). Abnormal pulmonary function was not significantly associated with any of the other variables studied, except for hypoxemia and restrictive lung disease. In this sample of children and adolescents with sickle cell disease, there was a significant prevalence of abnormal pulmonary function. The high prevalence of respiratory disorders suggests the need for a closer look at the lung function of this population, in childhood and thereafter. Avaliar a função pulmonar e a capacidade funcional em crianças e adolescentes com doença falciforme. Estudo transversal com 70 crianças e adolescentes com doença falciforme (8-15 anos), submetidos a testes de função respiratória (espirometria) e de capacidade funcional (teste de caminhada de seis minutos). Os resultados da avaliação da função pulmonar foram comparados com variáveis relacionadas à gravidade da doença falciforme e à presença de história de asma e de síndrome torácica aguda. Dos 64 pacientes submetidos à espirometria, 15 (23,4%) apresentaram resultados alterados: distúrbio ventilatório restritivo, em 8; (12,5%) e distúrbio respiratório obstrutivo, em 7 (10,9%). Dos 69 pacientes submetidos ao teste de caminhada de seis minutos, 18 (26,1%) apresentaram resultados alterados na distância em % do previsto para a idade, e houve uma queda ≥ 3% na SpO2 em 36 (52,2%) dos pacientes. Não houve associações significativas entre função pulmonar alterada e as outras variáveis analisadas, exceto para hipoxemia e distúrbio ventilatório restritivo. Observou-se uma significativa prevalência de alterações na função pulmonar nesta amostra de crianças e adolescentes com doença falciforme. A elevada prevalência de distúrbios ventilatórios sugere a necessidade de um olhar mais atento à função pulmonar desde a infância nessa população.

Mortimer, K.; Bjune, G.; El Sony, A. I.

2016-01-01

Background: Chronic respiratory disease (CRD) causes substantial morbidity and mortality. Although the global CRD epidemic collides with the tuberculosis (TB) epidemic in many low- and middle-income country settings, the risk of TB-associated CRD is not well described in countries with a high burden of TB. Methods: We recruited 136 patients with a history of sputum smear-positive pulmonary TB (PTB) from the TB clinic at Omdurman Teaching Hospital in Khartoum, Sudan, and 136 age- and sex-matched community controls, between 28 July 2013 and 30 December 2013. Data were collected using standardised questionnaires and spirometry was performed before and after bronchodilator. Results: The mean age of the subjects with previous PTB and controls was respectively 44.0 years (SD 8.5) and 44.5 years (SD 8.6), with 27.2% females in both groups. Chronic respiratory symptoms such as chronic cough (OR 6.67, 95%CI 2.98–14.90, P < 0.001) and the presence of chronic airflow obstruction (OR 12.4, 95%CI 1.56–98.40, P = 0.02) were both strongly associated with a past history of PTB after adjusting for potential confounders. Conclusion: The clinical features of CRDs are strongly associated with past history of PTB. An integrated approach to improve the management of these common conditions should be considered. Contexte : Les maladies respiratoires chroniques (MRC) sont à l'origine d'une morbidité et d'une mortalité considérables dans le monde. Bien que l'épidémie mondiale des MRC entre en conflit avec l'épidémie de tuberculose (TB) dans de nombreux pays à revenu faible ou moyen, le risque de MRC associée à la TB n'est pas bien décrit dans les pays durement frappés par la TB. Méthodes : Nous avons recruté 136 patients ayant des antécédents de tuberculose pulmonaire (TBP) à frottis positif dans le service de pneumologie du Centre Hospitalier Universitaire Omdurman à Khartoum, Soudan, et 136 témoins de la communauté, appariés sur l'âge et le sexe, entre le 28 juillet 2013 et le 30 décembre 2013. Les données ont été recueillies grâce à des questionnaires standardisés ainsi qu'à une spirométrie avant et après bronchodilatateur. Résultats : L'âge moyen des cas et des témoins a été de 44,0 ans (DS 8,5) et 44,5 ans (DS 8,61), respectivement, avec 27,2% de femmes dans les deux groupes. Des symptômes respiratoires chroniques comme une toux chronique (OR 6,67 ; IC95% 2,98–14,90 ; P < 0,001) et la présence d'une obstruction chronique des voies aériennes (OR 12,39 ; IC%95 1,56–98,40 ; P = 0,02) ont été tous deux fortement associés à des antécédents de TBP après ajustement sur les facteurs de confusion potentiels. Conclusion : Les caractéristiques cliniques des MRC sont fortement associées à des antécédents de TBP. Une approche intégrée visant à améliorer la prise en charge de ces pathologies fréquentes devrait être envisagée. Marco de referencia: La enfermedad pulmonar crónica (EPC) es una causa importante de morbilidad y mortalidad. Aunque la epidemia mundial de EPC rivaliza con la epidemia de tuberculosis (TB) en muchos entornos de países con bajos y medianos recursos, el riesgo de aparición de EPC asociado con la TB se ha descrito cabalmente en los países con una alta carga de morbilidad por TB. Métodos: Entre el 28 de julio y el 30 de diciembre del 2013, participaron en el estudio 136 pacientes con antecedente de tuberculosis pulmonar (TBP) y baciloscopia positiva del esputo que habían recibido tratamiento en el consultorio de neumología del Hospital Universitario Omdurman de Jartún, en Sudán, y 136 testigos sanos de la comunidad, emparejados en función de la edad y el sexo. Se recogieron datos mediante cuestionarios normalizados y se practicó una espirometría antes y despuès una prueba de broncodilatación. Resultados: El promedio de la edad en el grupo de los casos fue 44,0 (desviación estándar 8,5 años) y en el grupo de testigos fue 44,5 años (8,6 años); la proporción de mujeres en ambos grupos fue 27,2%. Se observó una fuerte asociación entre la presencia de síntomas respiratorios crónicos como la tos (OR 6,67; IC95% 2,98–14,90; P < 0,001) y la presencia de obstrucción crónica al flujo en las vías respiratorias (OR 12,39; IC95% 1,56–98,40; P = 0,02) en las personas con antecedente de TBP, una vez corregidos los posibles factores de confusión. Conclusión: La presencia de rasgos clínicos de EPC exhibe una fuerte correlación con el antecedente de TBP. Es preciso considerar la posibilidad de aplicar un enfoque integrado con el fin de mejorar la atención de ambas enfermedades tan frecuentes. PMID:27695684

Introduction Le but de cette étude était de déterminer la fréquence de la tuberculose (TB) chez le personnel de santé du secteur public en charge des patients tuberculeux et d’évaluer les facteurs de risque de contracter la tuberculose chez ce personnel au Burundi. Méthodes Il s’agit d’une étude transversale à visée analytique réalisée auprès de 300 travailleurs prestant dans 30 centres de dépistage et de traitement de la TB (CDT) au Burundi du 16 octobre au 15 novembre 2012. Les paramètres sociodémographiques et professionnels ainsi que l’antécédent de vaccination BCG de travailleurs ayant été touché par la TB ont été analysé et comparé à ceux de travailleurs qui ne l’ont pas été. Le seuil de signification a été fixé à p < 0,05. Résultats La fréquence de la TB chez le personnel de santé est de 15%. Le risque de souffrir de la TB est de près de 4 fois chez les travailleurs âgés d’au moins 50 ans (OR=3,73; 1,53-9,08), chez ceux qui n’ont jamais reçu de vaccin de BCG (OR=3,73; 1,24-11,03), chez ceux qui n’ont pas de cicatrice vaccinale de BCG (OR=3,80; 1,67-8,62) et chez ceux qui travaillent depuis au moins 6 ans dans un CDT (OR=3,79; 1,44-9,96); ce risque est de 9 fois chez ceux qui sont mariés (OR=9,42; 1,26-70,23), de 8 fois chez ceux qui n’aèrent pas leurs salles de travail (OR=8,20; 1,48-48,23) et de 6 fois chez ceux qui ont comme profession nettoyeur ou aide-soignant (OR=6,12; 2,92-12,82). Par contre, aucune corrélation statistiquement significative n’a été observée entre le fait de souffrir de la TB et le sexe mais aussi le nombre d’heures de contact d’un travailleur avec un patient tuberculeux (p>0,05). Conclusion L’âge, l’antécédent de vaccination de BCG ainsi que la majorité de paramètres professionnels sont en association avec la maladie TB des travailleurs de CDT. D’où, la maîtrise de certains facteurs de risque s’avère important pour faire face au fardeau de la TB parmi le personnel hospitalier. PMID:24847402

Conventional bronchoscopy has a low diagnostic yield for peripheral pulmonary lesions. Radial-probe EBUS employs a rotating ultrasound transducer at the end of a probe that is passed through the working channel of the bronchoscope. Radial-probe EBUS facilitates the localization of peripheral pulmonary nodules, thus increasing the diagnostic yield. The objective of this study was to present our initial experience using radial-probe EBUS in the diagnosis of peripheral pulmonary lesions at a tertiary hospital. We conducted a retrospective analysis of 54 patients who underwent radial-probe EBUS-guided bronchoscopy for the investigation of pulmonary nodules or masses between February of 2012 and September of 2013. Radial-probe EBUS was performed with a flexible 20-MHz probe, which was passed through the working channel of the bronchoscope and advanced through the bronchus to the target lesion. For localization of the lesion and for collection procedures (bronchial brushing, transbronchial needle aspiration, and transbronchial biopsy), we used fluoroscopy. Radial-probe EBUS identified 39 nodules (mean diameter, 1.9 ± 0.7 cm) and 19 masses (mean diameter, 4.1 ± 0.9 cm). The overall sensitivity of the method was 66.7% (79.5% and 25.0%, respectively, for lesions that were visible and not visible by radial-probe EBUS). Among the lesions that were visible by radial-probe EBUS, the sensitivity was 91.7% for masses and 74.1% for nodules. The complications were pneumothorax (in 3.7%) and bronchial bleeding, which was controlled bronchoscopically (in 9.3%). Radial-probe EBUS shows a good safety profile, a low complication rate, and high sensitivity for the diagnosis of peripheral pulmonary lesions. A broncoscopia convencional possui baixo rendimento diagnóstico para lesões pulmonares periféricas. A ecobroncoscopia radial (EBUS radial) emprega um transdutor ultrassonográfico rotatório na extremidade de uma sonda que é inserida no canal de trabalho do broncoscópio. O EBUS radial facilita a localização de nódulos pulmonares periféricos, aumentando assim o rendimento diagnóstico. O objetivo deste estudo foi apresentar nossa experiência inicial com o uso de EBUS radial para o diagnóstico de lesões pulmonares periféricas em um hospital terciário. Foi realizada uma análise retrospectiva de 54 pacientes submetidos à broncoscopia guiada por EBUS radial para a investigação de nódulos ou massas pulmonares entre fevereiro de 2012 e setembro de 2013. O EBUS radial foi realizado com uma sonda flexível de 20 MHz, que foi inserida no canal de trabalho do broncoscópio até chegar à lesão-alvo. A fluoroscopia foi usada para localizar a lesão e realizar procedimentos de coleta (escovado brônquico, aspiração transbrônquica com agulha e biópsia transbrônquica). O EBUS radial identificou 39 nódulos (média de diâmetro: 1,9 ± 0,7 cm) e 19 massas (média de diâmetro: 4,1 ± 0,9 cm). A sensibilidade global do EBUS radial foi de 66,7% (79,5% para as lesões visíveis pelo método e 25% para as lesões não visíveis pelo método). Nas lesões visíveis pelo método, a sensibilidade foi de 91,7% para massas e de 74,1% para nódulos. As complicações foram pneumotórax (3,7%) e sangramento brônquico controlado broncoscopicamente (9,3%). O EBUS radial apresenta bom perfil de segurança, baixo índice de complicações e alta sensibilidade para o diagnóstico de lesões pulmonares periféricas.

To evaluate the effects that administering dexamethasone before the induction of ventilator-induced lung injury (VILI) has on the temporal evolution of that injury. Wistar rats were allocated to one of three groups: pre-VILI administration of dexamethasone (dexamethasone group); pre-VILI administration of saline (control group); or ventilation only (sham group). The VILI was induced by ventilation at a high tidal volume. Animals in the dexamethasone and control groups were euthanized at 0, 4, 24, and 168 h after VILI induction. We analyzed arterial blood gases, lung edema, cell counts (total and differential) in the BAL fluid, and lung histology. At 0, 4, and 24 h after VILI induction, acute lung injury (ALI) scores were higher in the control group than in the sham group (p < 0.05). Administration of dexamethasone prior to VILI induction decreased the severity of the lung injury. At 4 h and 24 h after induction, the ALI score in the dexamethasone group was not significantly different from that observed for the sham group and was lower than that observed for the control group (p < 0.05). Neutrophil counts in BAL fluid were increased in the control and dexamethasone groups, peaking at 4 h after VILI induction (p < 0.05). However, the neutrophil counts were lower in the dexamethasone group than in the control group at 4 h and 24 h after induction (p < 0.05). Pre-treatment with dexamethasone also prevented the post-induction oxygenation impairment seen in the control group. Administration of dexamethasone prior to VILI induction attenuates the effects of the injury in Wistar rats. The molecular mechanisms of such injury and the possible clinical role of corticosteroids in VILI have yet to be elucidated. Avaliar os efeitos da administração de dexametasona antes da indução de lesão pulmonar induzida por ventilação mecânica (LPIVM) na evolução temporal dessa lesão. Ratos Wistar foram alocados em um dos três grupos: administração de dexametasona pré-LPIVM (grupo dexametasona); administração de salina pré-LPIVM (grupo controle); e somente ventilação (grupo sham). A LPIVM foi realizada por ventilação com volume corrente alto. Os animais dos grupos dexametasona e controle foram sacrificados em 0, 4, 24 e 168 h após LPIVM. Analisamos gasometria arterial, edema pulmonar, contagens de células (totais e diferenciais) no lavado broncoalveolar e histologia de tecido pulmonar. Em 0, 4 e 24 h após LPIVM, os escores de lesão pulmonar aguda (LPA) foram maiores no grupo controle que no grupo sham (p < 0,05). A administração de dexametasona antes da LPIVM reduziu a gravidade da lesão pulmonar. Em 4 e 24 h após a indução, o escore de LPA no grupo dexametasona não foi significativamente diferente daquele observado no grupo sham e foi menor que o observado no grupo controle (p < 0,05). As contagens de neutrófilos no lavado broncoalveolar estavam aumentadas nos grupos controle e dexametasona, com pico em 4 h após LPIVM (p < 0,05). Entretanto, as contagens de neutrófilos foram menores no grupo dexametasona que no grupo controle em 4 e 24 h após LPIVM (p < 0,05). O pré-tratamento com dexametasona também impediu o comprometimento da oxigenação após a indução visto no grupo controle. A administração de dexametasona antes de LPIVM atenua os efeitos da lesão em ratos Wistar. Os mecanismos moleculares dessa lesão e o possível papel clínico dos corticosteroides na LPIVM ainda precisam ser elucidados.

To compare somatic growth, lung function, and level of physical activity in schoolchildren who had been very-low-birth-weight preterm infants (VLBWPIs) or normal-birth-weight full-term infants. We recruited two groups of schoolchildren between 8 and 11 years of age residing in the study catchment area: those who had been VLBWPIs (birth weight < 1,500 g); and those who had been normal-birth-weight full-term infants (controls, birth weight ≥ 2,500 g). Anthropometric and spirometric data were collected from the schoolchildren, who also completed a questionnaire regarding their physical activity. In addition, data regarding the perinatal and neonatal period were collected from the medical records of the VLBWPIs. Of the 93 schoolchildren screened, 48 and 45 were in the VLBWPI and control groups, respectively. No significant differences were found between the groups regarding anthropometric characteristics, nutritional status, or pulmonary function. No associations were found between perinatal/neonatal variables and lung function parameters in the VLBWPI group. Although the difference was not significant, the level of physical activity was slightly higher in the VLBWPI group than in the control group. Among the schoolchildren evaluated here, neither growth nor lung function appear to have been affected by prematurity birth weight, or level of physical activity. Comparar o crescimento somático, a função pulmonar e o nível de atividade física entre escolares nascidos prematuros com muito baixo peso e escolares nascidos a termo e com peso adequado. Foram recrutados escolares com idade de 8 a 11 anos residentes na mesma área de abrangência do estudo: prematuros e com peso < 1.500 g e controles (nascidos a termo e com peso ≥ 2.500 g). Foram obtidas medidas antropométricas e espirométricas e aplicado um questionário sobre a atividade física. Além disso, foram coletadas informações do período perinatal/neonatal dos recém-nascidos com muito baixo peso (RNMBP) de seus prontuários médicos. Dos 93 escolares avaliados, 48 crianças no grupo RNMBP e 45 no grupo controle. Não houve diferenças significativas entre os grupos em relação às características antropométricas e nutricionais ou aos parâmetros de função pulmonar. Não foram encontradas associações entre as variáveis perinatais/neonatais e parâmetros da função pulmonar dos escolares no grupo RNMBP. Embora sem diferença significativa em relação aos níveis de atividade física, o grupo RNMBP apresentou uma tendência de ser mais ativo que o grupo controle. Nos escolares aqui estudados o crescimento e a função pulmonar parecem não ser afetados por prematuridade, peso ao nascimento ou nível de atividade física.

To evaluate diaphragmatic mobility in relation to lung function, respiratory muscle strength, dyspnea, and physical activity in daily life (PADL) in patients with COPD. We included 25 patients with COPD, classified according to the Global Initiative for Chronic Obstructive Lung Disease criteria, and 25 healthy individuals. For all of the participants, the following were evaluated: anthropometric variables, spirometric parameters, respiratory muscle strength, diaphragmatic mobility (by X-ray), PADL, and the perception of dyspnea. In the COPD group, diaphragmatic mobility was found to correlate with lung function variables, inspiratory muscle strength, and the perception of dyspnea, whereas it did not correlate with expiratory muscle strength or PADL. In patients with COPD, diaphragmatic mobility seems to be associated with airway obstruction and lung hyperinflation, as well as with ventilatory capacity and the perception of dyspnea, although not with PADL. Avaliar a relação da mobilidade diafragmática com a função pulmonar, força muscular respiratória, dispneia e atividade física de vida diária (AFVD) em pacientes com DPOC. Foram avaliados 25 pacientes com diagnóstico de DPOC, classificados de acordo com critérios da Global Initiative for Chronic Obstructive Lung Disease, e 25 indivíduos saudáveis. Todos foram submetidos às seguintes avaliações: mensuração antropométrica, espirometria, força muscular respiratória, mobilidade diafragmática (por radiografia), AFVD e percepção de dispneia. No grupo DPOC, houve correlações da mobilidade diafragmática com variáveis de função pulmonar, força muscular inspiratória e percepção de dispneia. Não houve correlações da mobilidade diafragmática com força muscular expiratória e AFVD. A mobilidade diafragmática parece estar associada tanto com a obstrução das vias aéreas quanto com a hiperinsuflação pulmonar em pacientes com DPOC, assim como com a capacidade ventilatória e percepção de dispneia, mas não com AFVD.

The delivery of cardiac patients is a challenge for the anaesthesiologist, to whom the welfare of both the mother and the foetus is a main issue. In case of caesarean section, advanced monitoring allows to optimize haemodynamic condition and to improve morbidity and mortality. To describe the use of pulse contour analysis calibrated by Trans-pulmonar thermodilution (Picco Plus(®)) for the perioperative management of a caesarean section in a patient with severe cardiomyopathy. We describe the case of a 28-year-old woman with a congenital heart disease who was submitted to a caesarean section under general anaesthesia for maternal pathology and foetal breech presentation. Intra- and post-operative management was optimized by advanced haemodynamic monitorization obtained by pulse contour wave analysis and thermodilution calibration (Picco Plus(®) monitor). The information about preload, myocardial contractility and postcharge was useful in guiding the fluid therapy and the use of vasoactive drugs. This case report illustrates the importance of advanced haemodynamic monitoring with an acceptably invasive device in obstetric patients with high cardiac risk. The increasing experience in advanced haemodynamic management will probably permit to decrease morbidity and mortality of obstetric patients in the future.

Background: Coronary artery bypass graft (CABG) is a standard surgical option for patients with diffuse and significant arterial plaque. This procedure, however, is not free of postoperative complications, especially pulmonary and cognitive disorders. Objective: This study aimed at comparing the impact of two different physiotherapy treatment approaches on pulmonary and cognitive function of patients undergoing CABG. Methods: Neuropsychological and pulmonary function tests were applied, prior to and following CABG, to 39 patients randomized into two groups as follows: Group 1 (control) - 20 patients underwent one physiotherapy session daily; and Group 2 (intensive physiotherapy) - 19 patients underwent three physiotherapy sessions daily during the recovery phase at the hospital. Non-paired and paired Student t tests were used to compare continuous variables. Variables without normal distribution were compared between groups by using Mann-Whitney test, and, within the same group at different times, by using Wilcoxon test. The chi-square test assessed differences of categorical variables. Statistical tests with a p value ≤ 0.05 were considered significant. Results: Changes in pulmonary function were not significantly different between the groups. However, while Group 2 patients showed no decline in their neurocognitive function, Group 1 patients showed a decline in their cognitive functions (P ≤ 0.01). Conclusion: Those results highlight the importance of physiotherapy after CABG and support the implementation of multiple sessions per day, providing patients with better psychosocial conditions and less morbidity.Fundamento: A cirurgia de revascularização miocárdica (CRM) é a opção cirúrgica padrão para pacientes com placas arteriais difusas e significativas. Tal procedimento, no entanto, não é desprovido de complicações pós-operatórias, especialmente distúrbios pulmonares e cognitivos. Objetivo: Comparar o impacto de duas abordagens fisioterapêuticas diferentes nas funções pulmonar e cognitiva de pacientes submetidos a CRM. Métodos: Testes de função pulmonar e neuropsicológicos foram aplicados, antes e após CRM, a 39 pacientes randomizados em dois grupos: Grupo 1 - 20 pacientes-controle submetidos a uma sessão de fisioterapia por dia; Grupo 2 - 19 pacientes submetidos a três sessões de fisioterapia por dia durante recuperação no hospital. Testes t de Student pareado e não pareado foram usados para comparar as variáveis contínuas. Variáveis sem distribuição normal foram comparadas entre os grupos usando-se o teste de Mann-Whitney, e, dentro do mesmo grupo em momentos diferentes, usando-se o teste de Wilcoxon. O teste do qui-quadrado avaliou diferenças das variáveis categóricas. Testes estatísticos com p valor ≤ 0,05 foram considerados significativos. Resultados: As alterações da função pulmonar não diferiram significativamente entre os grupos. Entretanto, o mesmo não ocorreu com a função neurocognitiva, que apresentou declínio no Grupo 1, mas não no Grupo 2 (p ≤ 0,01). Conclusão: Tais resultados reforçam a importância da fisioterapia após CRM e da realização de múltiplas sessões por dia, o que oferece aos pacientes melhores condições psicossociais e menos morbidade.

To evaluate the effects of exposure to emissions from sugar cane burning on inflammatory mechanisms in tissues of the trachea and lung parenchyma in Wistar rats after different periods of exposure. This was an experimental open randomized study. The animals were divided into four groups: a control group (CG) underwent standard laboratory conditions, and three experimental groups were exposed to emissions from sugar cane burning over different periods of time, in days-1 (EG1), 7 (EG7), and 21 (EG21). After euthanasia with 200 mg/kg of ketamine/xylazine, fragments of trachea and lung were collected and fixed in 10% formalin. Histological analyses were performed with H&E and picrosirius red staining. No inflammatory infiltrates were found in the tissues of CG rats. The histological examination of tissues of the trachea and lung parenchyma revealed that the inflammatory process was significantly more intense in EG7 than in the CG (p < 0.05 and p < 0.01, respectively). In comparison with the CG and EG1, angiogenesis in the lung parenchyma and collagen deposition in tracheal tissues were significantly greater only in EG21 (p < 0.001 and p < 0.01, respectively). In this sample, emissions from sugar cane burning induced acute focal and diffuse inflammation in the lamina propria of tracheal tissues, with no loss of ciliated epithelial tissue. In the lung parenchyma of the animals in the experimental groups, there was interstitial and alveolar edema, together with polymorphonuclear cell infiltrates. Avaliar os efeitos da exposição à fumaça da queima da cana-de-açúcar sobre mecanismos inflamatórios em tecidos de traqueia e de parênquima pulmonar de ratos Wistar após diferentes períodos de exposição. Estudo experimental, randomizado, não cego. Os animais foram divididos em quatro grupos: controle (GC), sob condições padrão de laboratório e os demais expostos à fumaça da queima da cana-de-açúcar por diferentes períodos: em 1 (GE1), 7 (GE7) e 21 (GE21) dias. Após a eutanásia com 200 mg/kg de ketamina/xilazina, foram coletados fragmentos de traqueia e pulmão e fixadas em formol 10%. Análises histológicas foram realizadas com coloração com H&E e picrosírius. Não houve infiltrado inflamatório nos tecidos no GC. O processo inflamatório na análise histológica de tecidos de traqueia e de parênquima pulmonar foi significativamente mais intenso no GE7 quando comparado ao GC (p < 0,05 e p < 0,01, respectivamente). Em comparação com os grupos GC e GE1, apenas no GE21 foi observada angiogênese significativa no parênquima pulmonar e aumento significativo de depósitos de colágeno em tecido de traqueia (p < 0,001 e p < 0,01, respectivamente). Nesta amostra, a fumaça da queima de cana-de-açúcar induziu processo inflamatório focal, difuso e agudo em tecidos de traqueia na lâmina própria, sem perda do tecido epitelial ciliado. Houve presença de edemas intersticiais e alveolares e infiltrados de células polimorfonucleares no parênquima pulmonar nos animais dos grupos experimentais.

To describe diagnostic and treatment aspects of hard metal lung disease (HMLD) and to review the current literature on the topic. This was a retrospective study based on the medical records of patients treated at the Occupational Respiratory Diseases Clinic of the Instituto do Coração, in the city of São Paulo, Brazil, between 2010 and 2013. Of 320 patients treated during the study period, 5 (1.56%) were diagnosed with HMLD. All of those 5 patients were male (mean age, 42.0 ± 13.6 years; mean duration of exposure to hard metals, 11.4 ± 8.0 years). Occupational histories were taken, after which the patients underwent clinical evaluation, chest HRCT, pulmonary function tests, bronchoscopy, BAL, and lung biopsy. Restrictive lung disease was found in all subjects. The most common chest HRCT finding was ground glass opacities (in 80%). In 4 patients, BALF revealed multinucleated giant cells. In 3 patients, lung biopsy revealed giant cell interstitial pneumonia. One patient was diagnosed with desquamative interstitial pneumonia associated with cellular bronchiolitis, and another was diagnosed with a hypersensitivity pneumonitis pattern. All patients were withdrawn from exposure and treated with corticosteroid. Clinical improvement occurred in 2 patients, whereas the disease progressed in 3. Although HMLD is a rare entity, it should always be included in the differential diagnosis of respiratory dysfunction in workers with a high occupational risk of exposure to hard metal particles. A relevant history (clinical and occupational) accompanied by chest HRCT and BAL findings suggestive of the disease might be sufficient for the diagnosis. Descrever aspectos relacionados ao diagnóstico e tratamento de pacientes com doença pulmonar por metal duro (DPMD) e realizar uma revisão da literatura. Estudo retrospectivo dos prontuários médicos de pacientes atendidos no Serviço de Doenças Respiratórias Ocupacionais do Instituto do Coração, localizado na cidade de São Paulo, entre 2010 e 2013. Entre 320 pacientes atendidos no período do estudo, 5 (1,56%) foram diagnosticados com DPMD. Todos os pacientes eram do sexo masculino, com média de idade de 42,0 ± 13,6 anos e média de tempo de exposição a metal duro de 11,4 ± 8,0 anos. Os pacientes foram submetidos a avaliação clinica, história ocupacional, TCAR de tórax, prova de função pulmonar, broncoscopia com LBA e biópsia pulmonar. Todos apresentaram distúrbio ventilatório restritivo. O achado de imagem à TCAR de tórax mais frequente foi de opacidades em vidro fosco (em 80%). Em 4 pacientes, o LBA revelou presença de células gigantes multinucleadas. Em 3, foi diagnosticada pneumonia intersticial por células gigantes na biópsia pulmonar. Houve o diagnóstico de pneumonia intersticial descamativa associada à bronquiolite celular em 1 paciente e de pneumonite de hipersensibilidade em 1. Todos foram afastados da exposição e tratados com corticoide. Houve melhora em 2 pacientes e progressão da doença em 3. Apesar de ser uma entidade rara, a DPMD deve ser sempre considerada em trabalhadores com risco ocupacional elevado de exposição a metais duros. A história clínica e ocupacional associada a achados em TCAR de tórax e LBA sugestivos da doença podem ser suficientes para o diagnóstico.

Introduction Cette étude a eu pour objectifs de diagnostiquer la tuberculose pulmonaire par l'examen microscopique et par la PCR des crachats et de déterminer les bases moléculaires de la résistance à la rifampicine et à l'isoniazide. Méthodes Le diagnostic du Complexe Mycobacterium Tuberculosis (CMTB) a été effectué par microscopie après coloration au Ziehl Nielsen et par PCR en temps réel en utilisant le kit d'identification du complexe MTB (Sacace Biotechnologie, Italie). Les résistances à la Rifampicine et à l'Isoniazide ont été étudiées par la technique de la PCR en utilisant le kit MTB résistance 8 (Sacace, Biotechnologie). Résultats Sur les 59 patients diagnostiqués pour la tuberculose pulmonaire, 59,3% étaient positifs en microscopie optique et 44,1% étaient positifs par PCR en Temps réel. Les résistances à la rifampicine (rpoB) et à l'isoniazide (katG et inhA) ont été observées chez 9 patients. La résistance à la rifampicine était due aux mutations (Asp516Val, Ser531Trp, Leu533Pro) et celle à l'isoniazide par les substitutions Ser315Thr du gène katG et C209T du gène inhA. Les multi résistances à la rifampicine et à l'isoniazide ont été observées dans 55,5% des échantillons et concernaient les associations: ropBAsp513Val + inhAC209T et rpoBLeu533Pro + katGSer315Thr. Conclusion La PCR en temps réel qui permet l'identification des allèles mutants rpoB, katG et inhA de M. tuberculosis est un outil de diagnostic épidémiologique de grande importance car elle permet de déterminer le niveau de résistance à la rifampicine et à l'isoniazide.

To evaluate the role of intrapleural positioning of a pleural catheter in early lung expansion and pleurodesis success in patients with recurrent malignant pleural effusion (RMPE). This was a retrospective study nested into a larger prospective cohort study including patients with RMPE recruited from a tertiary university teaching hospital between June of 2009 and September of 2014. The patients underwent pleural catheter insertion followed by bedside pleurodesis. Chest CT scans were performed twice: immediately before pleurodesis (iCT) and 30 days after pleurodesis (CT30). Catheter positioning was categorized based on iCT scans as posterolateral, anterior, fissural, and subpulmonary. We used the pleural volume on iCT scans to estimate early lung expansion and the difference between the pleural volumes on CT30 and iCT scans to evaluate radiological success of pleurodesis. Clinical pleurodesis success was defined as no need for any other pleural procedure. Of the 131 eligible patients from the original study, 85 were included in this nested study (64 women; mean age: 60.74 years). Catheter tip positioning was subpulmonary in 35 patients (41%), anterior in 23 (27%), posterolateral in 17 (20%), and fissural in 10 (12%). No significant differences were found among the groups regarding early lung expansion (median residual pleural cavity = 377 mL; interquartile range: 171-722 mL; p = 0.645), radiological success of pleurodesis (median volume = 33 mL; interquartile range: -225 to 257 mL; p = 0.923), and clinical success of pleurodesis (85.8%; p = 0.676). Our results suggest that the position of the tip of the pleural catheter influences neither early lung expansion nor bedside pleurodesis success in patients with RMPE. Avaliar o papel do posicionamento intrapleural do cateter pleural na expansão pulmonar precoce e no sucesso da pleurodese em pacientes com derrame pleural maligno recorrente (DPMR). Trata-se de um estudo retrospectivo aninhado em um estudo prospectivo de coorte maior com pacientes com DPMR recrutados em um hospital-escola universitário terciário entre junho de 2009 e setembro de 2014. Os pacientes foram submetidos a inserção de cateter pleural e, em seguida, pleurodese à beira do leito. A TC de tórax foi realizada duas vezes: imediatamente antes da pleurodese (TCi) e 30 dias após a pleurodese (TC30). Com base na TCi, a posição do cateter foi classificada em posterolateral, anterior, fissural e subpulmonar. Usamos o volume pleural na TCi para estimar a expansão pulmonar precoce e a diferença entre os volumes pleurais na TC30 e na TCi a fim de avaliar o sucesso radiológico da pleurodese. Considerou-se que a pleurodese teve êxito clínico quando não foi necessário realizar nenhum outro procedimento pleural. Dos 131 pacientes elegíveis do estudo original, 85 foram incluídos neste estudo aninhado (64 mulheres; média de idade: 60,74 anos). A posição da ponta do cateter foi subpulmonar em 35 pacientes (41%), anterior em 23 (27%), posterolateral em 17 (20%) e fissural em 10 (12%). Não houve diferenças significativas entre os grupos quanto à expansão pulmonar precoce (mediana da cavidade pleural residual = 377 ml; intervalo interquartil: 171-722 ml; p = 0,645), sucesso radiológico da pleurodese (mediana do volume = 33 ml; intervalo interquartil: -225 a 257 ml; p = 0,923) e sucesso clínico da pleurodese (85,8%; p = 0,676). Nossos resultados sugerem que a posição da ponta do cateter pleural não influencia nem a expansão pulmonar precoce nem o sucesso da pleurodese à beira do leito em pacientes com DPMR.

Studies characterizing asthma phenotypes have predominantly included adults or have involved children and adolescents in developed countries. Therefore, their applicability in other populations, such as those of developing countries, remains indeterminate. Our objective was to determine how low-income children and adolescents with asthma in Brazil are distributed across a cluster analysis. We included 306 children and adolescents (6-18 years of age) with a clinical diagnosis of asthma and under medical treatment for at least one year of follow-up. At enrollment, all the patients were clinically stable. For the cluster analysis, we selected 20 variables commonly measured in clinical practice and considered important in defining asthma phenotypes. Variables with high multicollinearity were excluded. A cluster analysis was applied using a twostep agglomerative test and log-likelihood distance measure. Three clusters were defined for our population. Cluster 1 (n = 94) included subjects with normal pulmonary function, mild eosinophil inflammation, few exacerbations, later age at asthma onset, and mild atopy. Cluster 2 (n = 87) included those with normal pulmonary function, a moderate number of exacerbations, early age at asthma onset, more severe eosinophil inflammation, and moderate atopy. Cluster 3 (n = 108) included those with poor pulmonary function, frequent exacerbations, severe eosinophil inflammation, and severe atopy. Asthma was characterized by the presence of atopy, number of exacerbations, and lung function in low-income children and adolescents in Brazil. The many similarities with previous cluster analyses of phenotypes indicate that this approach shows good generalizability. Estudos que caracterizam fenótipos de asma predominantemente incluem adultos ou foram realizados em crianças e adolescentes de países desenvolvidos; portanto, sua aplicabilidade em outras populações, tais como as de países em desenvolvimento, permanece indeterminada. Nosso objetivo foi determinar como crianças e adolescentes asmáticas de baixa renda no Brasil são distribuídos através de uma análise de clusters. Foram incluídos 306 crianças e adolescentes (6-18 anos de idade) com diagnóstico clínico de asma e sob tratamento médico por pelo menos um ano de acompanhamento. No momento da inclusão, todos os pacientes estavam clinicamente estáveis. Vinte variáveis comumente determinadas na prática clínica e consideradas importantes na definição dos fenótipos de asma foram selecionadas para a análise de clusters. As variáveis com alta multicolinearidade foram excluídas. Uma análise de clusters foi realizada utilizando-se um teste aglomerativo em duas etapas e log-likelihood distance measure. Três clusters foram definidos para nossa população. O cluster 1 (n = 94) incluiu indivíduos com função pulmonar normal, inflamação eosinofílica leve, poucas exacerbações, início mais tardio da asma e atopia leve. O cluster 2 (n = 87) incluiu pacientes com função pulmonar normal, número moderado de exacerbações, início precoce da asma, inflamação eosinofílica mais grave e atopia moderada. O cluster 3 (n = 108) incluiu pacientes com função pulmonar ruim, exacerbações frequentes, inflamação eosinofílica e atopia graves. A asma foi caracterizada por presença de atopia, número de exacerbações e função pulmonar em crianças e adolescentes de baixa renda no Brasil. As muitas semelhanças entre esta e outras análises de clusters de fenótipos indicam que essa abordagem apresenta boa generalização.

En transplantation, les complications infectieuses sont fréquentes et de diagnostic souvent délicat. Elles peuvent coexister chez le transplanté rénal rendant leur diagnostic encore plus difficile. Le but de ce cas clinique est de discuter les difficultés diagnostiques et de surveillance de deux types de pathologies assez fréquentes chez le transplanté rénal, qui sont la tuberculose et la mycose, à travers l’observation clinique d’une patiente de 24 ans transplantée rénale qui présente une spondylodiscite tuberculeuse et qui développe secondairement une septicémie à Candida non albicans à point de départ urinaire dont le seul point d’appel est la fièvre post opératoire.

Cette étude rapporte les aspects cliniques et évolutifs des séquelles pulmonaires tuberculeuses (SPT) opérées chez les séropositifs (VIH+). Il s'agit d'une étude prospective transversale réalisée entre Novembre 2005 et Octobre 2012. Elle a porté sur 20 patients VIH+, ayant dans leurs antécédents, une tuberculose pulmonaire (TP) traitée et déclarée guérie, et admise dans ladite période pour une chirurgie de la SPT secondaire. Une enquête sérologique VIH a été réalisée systématiquement au cours du bilan pré-opératoire. Le diagnostic pré-opératoire de la SPT, la mortalité, les complications post- opératoires (CPOP), le séjour hospitalier, le suivi à moyen terme des STP opérées ont été évalués. Les séropositifs étaient VIH1+ (n = 12; 60%), VIH1&2+ (n = 4; 20%) et VIH2+ (n = 4; 20%). La durée moyenne d’évolution des STP était de 26,22 ± 21,3 mois. Les STP étaient les pyothorax ou pleurésies enkystées (n = 16; 80%), le poumon détruit (n = 2;10%) et les dilatations de bronches (n = 2;10%). Les VIH+ ne présentaient pas d'aspergillome pulmonaire. Le séjour hospitalier moyen était 13,1 ± 10,2 jours. Le suivi total était de 82 patients-année avec une moyenne de suivi de 4,2 ± 2,3 ans (extrêmes: 1 et 7 ans). Le taux de mortalité à court et moyen terme était nul. Aucun décès post-opératoire immédiat n'a été noté. Les CPOP immédiates étaient les bullages prolongés chez 75% des immunodéprimés. Les CPOP tardives (n = 3) étaient un syndrome restrictif pulmonaire, un pyothorax persistant et une pachypleurite résiduelle restrictive. A court terme, le taux de guérison radiologique était de 80% (n = 16). PMID:24932331

Introduction La tuberculose (TB) reste de nos jours un problème majeur de santé publique dans les pays en voie de développement. Elle devient de plus en plus importante à cause de l'infection au VIH. Cette étude avait pour but de caractériser les patients admis dans le plus grand Centre de Diagnostic et de Traitement de la Tuberculose (CDT) de l'Ouest Cameroun entre 2000 et 2009. Méthodes Les patients de 15 ans et plus admis au CDT de Baleng durant la période allant du 1er janvier 2000 au 31 décembre 2009 ont été inclus. Les données ont étés collectées grâce à une grille pré conçue. Le calcul des fréquences, moyennes et les comparaisons de groupes ont été faites pour ressortir les caractéristiques des participants. Résultats 2556 patients ont été inclus dans l’étude. 64,8% étaient de sexe masculin et l’âge médian étaient de 33ans. 2141 (83,7%) de patients présentaient une TPM+, 319 (12,5%) une TPM- et 96 (3,8%) une TEP. 64,7% des patients résidaient hors du district de santé d'implantation du CDT. 79,16% de patients tuberculeux ont fait le test de dépistage du VIH et la séroprévalence chez ceux testés était de 26,06%. Les différentes évolutions en fin de période de suivi de chaque patient ont été les suivantes: évolution favorable (guéri et traitement terminé) 1954(76,6%); perdus de vue 231(9,0%); décès 230(9,0%); transféré 92(3,6%); échec 49(1,9%). Conclusion Une proportion considérable de patients résident loin du CDT ce qui augmenterait le perdus de vue et les transferts pendant le traitement. En plus vulgariser les autres CDT de la région, il est nécessaire de renforcer le système de transfert pour éviter les perdus de vue entre deux CDT. PMID:24570799

To analyze the accuracy of deterministic and probabilistic record linkage to identify TB duplicate records, as well as the characteristics of discordant pairs. The study analyzed all TB records from 2009 to 2011 in the state of Rio de Janeiro. A deterministic record linkage algorithm was developed using a set of 70 rules, based on the combination of fragments of the key variables with or without modification (Soundex or substring). Each rule was formed by three or more fragments. The probabilistic approach required a cutoff point for the score, above which the links would be automatically classified as belonging to the same individual. The cutoff point was obtained by linkage of the Notifiable Diseases Information System - Tuberculosis database with itself, subsequent manual review and ROC curves and precision-recall. Sensitivity and specificity for accurate analysis were calculated. Accuracy ranged from 87.2% to 95.2% for sensitivity and 99.8% to 99.9% for specificity for probabilistic and deterministic record linkage, respectively. The occurrence of missing values for the key variables and the low percentage of similarity measure for name and date of birth were mainly responsible for the failure to identify records of the same individual with the techniques used. The two techniques showed a high level of correlation for pair classification. Although deterministic linkage identified more duplicate records than probabilistic linkage, the latter retrieved records not identified by the former. User need and experience should be considered when choosing the best technique to be used. Analisar a acurácia das técnicas determinística e probabilística para identificação de registros duplicados de tuberculose, assim como as características dos pares discordantes. Foram analisados todos os registros de tuberculose no período de 2009 a 2011 do estado do Rio de Janeiro. Foi desenvolvido algoritmo para relacionamento determinístico, usando conjunto de 70 regras, a partir da combinação de fragmentos das variáveis-chave com ou sem modificações (Soundex ou substring). Cada regra era formada por três ou mais fragmentos. Para a abordagem probabilística, foi necessário estabelecer ponto de corte para o escore, acima do qual os links seriam classificados automaticamente como pertencentes ao mesmo indivíduo. O ponto de corte foi obtido por meio do relacionamento da base de dados Sistema de Informação de Agravos de Notificação - Tuberculose com ela mesma, posterior revisão manual e curvas ROC e precision-recall. Foram calculadas a sensibilidade e especificidade para análise de acurácia. A acurácia variou de 87,2% a 95,2% para sensibilidade e 99,8% a 99,9% para especificidade para as técnicas probabilística e determinística, respectivamente. A presença de valores faltantes para as variáveis-chave e o baixo percentual da medida de similaridade para o nome e data de nascimento foram os principais responsáveis pela não identificação dos registros do mesmo indivíduo pelas técnicas utilizadas. As duas técnicas apresentam alta concordância para a classificação como par. Apesar de a técnica determinística ter identificado mais registros duplicados que a probabilística, a segunda recuperou registros não identificados pela primeira. A necessidade e a experiência do usuário devem ser consideradas para a escolha da técnica a ser utilizada.

Nonspecific interstitial pneumonitis (NSIP) initially described by Katzenstein and Fiorelli in 1994, seems to be a distinct clinicopathologic entity among idiopathic interstitial pneumonitis (IIP). Besides different histologic features from other IIP, NSIP is characterized by a better long-term outcome, associated with a better steroids responsiveness than idiopathic pulmonar fibrosis (IPF), where usually were included. Thus, differentiating NSIP from other IIP, namely IPF is very significant, since it has important therapeutic and prognostic implications. NSIP encloses different pathologies, namely those with inflammatory predominance (cellular subtype) or fibrous predominance (fibrosing subtype). NSIP is reviewed and discussed by the authors, after two clinical cases description.

Systemic diseases affecting the cornea have a wide range of manifestations. The detailed study of all pathologies that cause corneal alteration is unapproachable, so we have centered our interest in the most prevalent or characteristic of them. In this paper we have divided these pathologies in sections to facilitate their study. Pulmonar and conective tissue (like colagen, rheumatologic and idiopathic inflamatory diseases), dermatologic, cardiovascular, hematologic, digestive and hepatopancreatic diseases with corneal alteration are described. Endocrine and metabolic diseases, malnutrition and carential states are also studied, as well as some otorhinolaryngologic and genetic diseases that affect the cornea. Finally, a brief report of ocular toxicity induced by drugs is referred.

Hydatid disease (HD) is a worldwide parasitic disease. Echinococcosis may involve many organs but affect most commonly liver and lungs. The location of echinococcal cysts inside pulmonary artery is extremely rare. Radiologic findings range from purely cystic lesions to a completely solid appearance. Hydatid cysts (HC) can be solitary or multiple and varies size. Pulmonary artery embolism of HC can be symptomatic or asymptomatic. When symptomatic, we see the chest pain, dyspnea, cough, hemoptysis and sometimes acute cor pulmonale or sudden death secondary to massive giant pulmonary artery embolism of HC.

Analyzing statements of health professionals from a Street Clinic regarding care of a homeless population with tuberculosis. This is a qualitative research, conducted in the central region of São Paulo at three basic health units in the period of November to December 2014. A semi-structured interview guideline was implemented for data collection and all interviews were recorded using a digital recorder. Six health professionals were interviewed. According to the Discourse Analysis perspective, three discursive segments emerged: experiences on care in the streets; weaknesses inherent to the treatment process; and incentives as a means of maintaining sick people in treatment. Caring for a the homeless population with tuberculosis constitutes a new and challenging experience. It involves difficulties in dealing with the reality of a miserable social context, a lack and inadequacy of services, as well as care limitations for treatment and treatment dropout, which reinforces multiresistance. However, the investigated Street Clinic teams seek to expand access to health and social care services to this population. Analisar os discursos dos profissionais de saúde do Consultório na Rua em relação ao cuidado à pessoa em situação de rua com tuberculose. Trata-se de uma pesquisa qualitativa, realizada na região central do município de São Paulo, em três Unidades Básicas de Saúde, no período de novembro a dezembro de 2014. Utilizou-se de um roteiro de entrevista semiestruturada para a coleta de dados e todas as entrevistas foram gravadas com recurso a um gravador digital. Foram entrevistados seis profissionais de saúde. Segundo a perspectiva da Análise de Discurso, emergiram três blocos discursivos: experiência sobre o cuidar na rua; fragilidades inerentes ao processo de tratamento e incentivos como meio para a permanência do sujeito doente no tratamento. Cuidar da pessoa com tuberculose e em situação de rua constitui uma experiência nova e desafiadora, implica dificuldades em lidar com a realidade de um contexto social miserável, falta e inadequação de serviços, bem como limitações do cuidado para a cura e abandono do tratamento, podendo reforçar a multirresistência. Contudo, as equipes de Consultório na Rua investigadas buscam ampliar o acesso aos serviços de saúde e assistência social a essa população.

The objective of this study was to describe the circumstances that promoted the implementation of the new Program for Action Against Tuberculosis in Brazil (Programa de Ação na Luta contra a Tuberculose no Brasil) and discuss the strategies used by registered nurses from the Santa Maria State Hospital, Guanabara State, to adjust nursing care to the new program against tuberculosis. This was performed through document research, interviews, and statements from nurses working at the time of the reorganization. Documents were analyzed based on the concepts of habitus, field, and symbolic power by Pierre Bourdieu, and included written and oral documents as well as secondary sources. The reorganization of the nursing service was performed under the leadership of a nurse whose symbolic capital assigned power and prestige to implement the necessary changes. It is concluded that the work of that nurse made it possible to implement the new program and contributed to establishing the position and importance of the registered nurse in providing care to individuals with tuberculosis, for prevention and cure.

To analyze the various factors in an in vitro fertilization and embryo transfer (IVF-ET) program which may affect the clinical pregnacy rate. A retrospective study was done on 559 IVF-ET cycles from 1992-Nov. 1995. The indication for treatment was bilateral tubal blockage. The chi 2 analysis of single factor variants with SPSS-PC + V3.0 was used for statistics. The overall clinical pregnancy rate in 559 cycles was 21.6%. The cause of tubal blockage due to tuberculoses consisted of 28.4%, and 34.9% of secondary sterility had the history of artificial abortion. The changes of environment, the different causes of tubal blockage, the history of previous intrauterine pregnancy did not affect the clinical pregnancy rate. When the number of embryos transferred increased to 5, the clinical pregnancy rate was highest 32.5%. The cumulative embryo score or embryo quality was related significantly with clinical pregnancy rate. The number and quality of embryos transferred are important factors affecting the clinical pregnancy rate. However, measures to prevent high-order multiple pregnancy and studies on the survival potential of embryos besides their morphology should be emphasized.

Background: Cardiovascular urgencies are frequent reasons for seeking medical care. Prompt and accurate medical diagnosis is critical to reduce the morbidity and mortality of these conditions. Objective: To evaluate the use of a pocket-size echocardiography in addition to clinical history and physical exam in a tertiary medical emergency care. Methods: One hundred adult patients without known cardiac or lung diseases who sought emergency care with cardiac complaints were included. Patients with ischemic changes in the electrocardiography or fever were excluded. A focused echocardiography with GE Vscan equipment was performed after the initial evaluation in the emergency room. Cardiac chambers dimensions, left and right ventricular systolic function, intracardiac flows with color, pericardium, and aorta were evaluated. Results: The mean age was 61 ± 17 years old. The patient complaint was chest pain in 51 patients, dyspnea in 32 patients, arrhythmia to evaluate the left ventricular function in ten patients, hypotension/dizziness in five patients and edema in one patient. In 28 patients, the focused echocardiography allowed to confirm the initial diagnosis: 19 patients with heart failure, five with acute coronary syndrome, two with pulmonary embolism and two patients with cardiac tamponade. In 17 patients, the echocardiography changed the diagnosis: ten with suspicious of heart failure, two with pulmonary embolism suspicious, two with hypotension without cause, one suspicious of acute coronary syndrome, one of cardiac tamponade and one of aortic dissection. Conclusion: The focused echocardiography with pocket-size equipment in the emergency care may allow a prompt diagnosis and, consequently, an earlier initiation of the therapy.Fundamento: As urgências cardiovasculares são causas importantes de procura por atendimento médico, sendo fundamentais a rapidez e a precisão no diagnóstico para diminuir sua morbimortalidade. Objetivo: Avaliar o uso da ecocardiografia direcionada como complemento diagnóstico ao exame físico em um serviço terciário de emergências clínicas. Métodos: Foram incluídos cem pacientes adultos sem doenças cardíacas ou pulmonares conhecidas que procuraram atendimento de urgência com queixas cardiológicas. Foram excluídos pacientes com alterações isquêmicas no eletrocardiograma ou febre. A ecocardiografia direcionada foi realizada logo após a avaliação inicial do paciente na sala de emergência, com aparelho ultraportátil GE Vscan, avaliando subjetivamente: dimensões das cavidades, função sistólica ventricular, fluxos intracardíacos pelo mapeamento de fluxo em cores, pericárdio e aorta. Resultados: A idade média dos pacientes foi 61 ± 17 anos. O quadro clínico inicial foi dor torácica (52 pacientes), dispneia (32 pacientes), arritmia/avaliação da função ventricular (dez pacientes), hipotensão/tontura (cinco pacientes) e edema periférico (um paciente). Em 28 pacientes a ecocardiografia direcionada confirmou a hipótese diagnóstica inicial: 19 pacientes com insuficiência cardíaca, cinco com síndrome coronariana aguda, dois com tromboembolismo pulmonar e dois com tamponamento cardíaco. Em 17 pacientes, a ecocardiografia direcionada alterou o diagnóstico, afastando a hipótese clínica inicial em dez casos com suspeita de insuficiência cardíaca, dois com suspeita de tromboembolismo pulmonar, dois com hipotensão a esclarecer, e em cada um dos três restantes com suspeitas de síndrome coronariana aguda, tamponamento cardíaco e dissecção de aorta. Conclusão: A ecocardiografia direcionada ultraportátil em serviço de emergências clínicas pode definir rapidamente o diagnóstico e, com isso, é possível iniciar mais precocemente o tratamento adequado.

To determine the tolerance and efficacy of a fixed proportion combination of 3 antituberculosis drugs (per tablet: 50 mg isoniazid + 120 mg rifampicin + 300 mg pyrazinamide) given during the first 2 months of a daily 6-month chemotherapy regimen. Random prospective treatment trial comparing a group of 124 patients receiving the triple combination with another group of 126 patients receiving the 3 drugs separately during the initial treatment phase. The continuation phase was identical for the 2 groups. Comparison of tolerance in the first 2 months, and of the failure and relapse rates (respectively at the end of treatment and 24 months after the end of treatment). During the first 2 months side-effects were significantly more common in the group receiving the drugs separately. At the end of treatment and during the following 24 months there were no significant differences in the cumulative rates of observed failures and relapses (2% and 1%). The triple combination studied could replace the separate drugs in the initial treatment phase in countries where the bioavailability of the drugs used has been proven.

OBJECTIVE To assess the quality of tuberculosis (TB) surveillance in Haiti, including whether underreporting from facilities to the national level contributes to low national case registration. METHODS We collected 2010 and 2012 TB case totals, reviewed laboratory registries, and abstracted individual TB case reports from 32 of 263 anti-tuberculosis treatment facilities randomly selected after stratification/weighting toward higher-volume facilities. We compared site results to national databases maintained by a non-governmental organization partner (International Child Care [ICC]) for 2010 and 2012, and the National TB Program (Programme National de Lutte contre la Tuberculose, PNLT) for 2012 only. RESULTS Case registries were available at 30/32 facilities for 2010 and all 32 for 2012. Totals of 3711 (2010) and 4143 (2012) cases were reported at the facilities. Case totals per site were higher in site registries than in the national databases by 361 (9.7%) (ICC 2010), 28 (0.8%) (ICC 2012), and 31 (0.8%) cases (PNLT 2012). Of abstracted individual cases, respectively 11.8% and 6.8% were not recorded in national databases for 2010 (n = 323) and 2012 (n = 351). CONCLUSIONS The evaluation demonstrated an improvement in reporting registered TB cases to the PNLT in Haiti between 2010 and 2012. Further improvement in case notification will require enhanced case detection and diagnosis. PMID:26260822

Le lupus induit est défini comme un syndrome lupique généralement cutanéo-articulaire secondaire à une exposition continue à un traitement et qui disparaît après arrêt de celle-ci. Nous rapportons deux cas de lupus induit par l'isoniazide. Il s'agissait de deux femmes âgées respectivement de 30 et 35 ans. Elles présentaient un lupus induit par l'isoniazide après un et deux mois de traitement d'une tuberculose ganglionnaire. La maladie s'est manifestée par des signes articulaires, une éruption cutanée, une leucopénie et une anémie. Les anticorps antinucléaires et les anticorps antihistone étaient présents dans le sérum des deux malades. L’évolution était favorable après arrêt de l'isoniazide et une corticothérapie per os. Les médicaments antituberculeux notamment l'isoniazide sont responsables d'effets indésirables fréquents. Le lupus induit doit être évoqué lorsqu'un patient présente un tableau clinico-biologique évocateur. PMID:26430478

Introduction L'objectif de ce travail était d'évaluer les différents facteurs associés à la dissociation immunovirologique malgré un traitement antirétroviral hautement actif et efficace. Méthodes Il s'agissait d'une étude de cohorte historique, descriptive et analytique faite à partir de dossiers de patients infectés par le VIH-1; sous traitement antirétroviral depuis au moins 12 mois, suivis dans la cohorte du CTA de 2001 à 2011 et ayant une charge virale indétectable depuis 6 mois. Résultats Durant cette période d'étude de 10 ans, la prévalence de la DIV était de 19,3%. Le sexe féminin était prédominant avec un sexe ratio de 1,9. La dissociation immunovirologique a été plus fréquemment rencontrée chez les patients de sexe masculin (29,7% vs 14,1%) avec une différence statistiquement significative (p = 0,00006). L'âge médian était de 44 ans ± 10 ans. Un antécédent de tuberculose a été retrouvé dans environ un tiers des cas (31,4%). La dissociation immunovirologique était significativement plus fréquente chez les patients ayant un antécédent de tuberculose (p = 0,00005). La plupart des patients (68%) était au stade SIDA 3 ou 4 de l'OMS. Les patients ayant une dissociation immunovirologique étaient plus souvent aux stades 3 et 4 de l'OMS (p = 0,0001). La dénutrition a été notée dans plus de la moitié des cas (56,2%) et la dissociation immunovirologique prédominait chez les patients dénutris (p=0,005). Le taux moyen de lymphocytes TCD4+ était de 86,7± 83 cellules / mm3. La dissociation immunovirologique était plus fréquente chez les patients ayant un taux de lymphocytes TCD4 bas à l'initiation avec une différence statistiquement significative (p = 0,00000). En analyse multivariée; Seuls l'âge supérieur ou égal à 43 ans, le taux de CD4 initial < 100 c/mm3 et le sexe masculin étaient significativement associés à cette dissociation immunovirologique. Conclusion Les principaux facteurs associés à la dissociation immunovirologique étant évalués, d'autres études portant sur ce groupe mériteraient d'être envisagées afin de connaitre l'impact de cette réponse immunologique partielle sur la survenue d'infections opportunistes ou bien la mise en place d'une trithérapie spécifique uniquement dans le but d'avoir une restauration immunologique optimale.

Five patients with CF (cystic fibrosis) dead between 1974 to 1982 at ages ranging from one to six months are presented. All of them showed edema, hypoalbuminemia and anemia in a severely compromised clinical situation, and failure to gain weight in spite of being breast-fed in the first weeks of life, in four of them. All of them were second or third degree malnourished babies (Gomez classification) at admission. Five children presented edema, two severe, two moderate and one mild. Hematocrit values ranged from 19% to 39% (means 26.4%), and albuminemia from 1.60 to 3.00 g/% (means 2.14 g/%). Two patients presented antecedents of dead brothers. All of them received substitution therapy with pancreatic enzymes. The children dead within seven and seventeen days of admission (means ten days) of broncho-pulmonar disfunction. In this work, we wish to call the pediatrician's attention about the importance of making this diagnostic presumption in the first months of the life.

Resumo Algumas infecções virais sistêmicas podem estar relacionadas ao desenvolvimento de trombose venosa profunda e/ou embolia pulmonar. Essa associação já está bem descrita em pacientes com infeções pelo vírus da imunodeficiência humana (HIV), hepatite C ou influenza. Recentemente introduzido no continente americano, o vírus chicungunha, agente etiológico da febre de chicungunha, ainda não tem essa relação bem sedimentada, mas com o aumento progressivo de sua incidência e pelo fato dessa infecção causar, muitas vezes, uma restrição severa da locomoção por poliartralgia e uma possível lesão endotelial direta, casos de tromboembolismo venoso podem começar a ser descritos. Neste relato de caso, descrevemos um paciente que desenvolveu trombose de veia poplítea direita durante internação para tratamento de febre por infecção por vírus chicungunha e poliartralgia severa.

L′actinomycose est une affection bactérienne granulomateuse, suppurative, étendue et chronique provoquée par la bactérie anaérobique gram positif Actinomyces israelii. La localisation thoracique est rare, elle peut simuler une pathologie néoplasique ou une tuberculose. Il s’agit d’un patient de 54ans sans antécédents pathologiques, qui s’est présenté avec deux tuméfactions pariétales basithoarciques droites, l’une antérieure et l’autre postérieure s’accompagnant d’une altération de l’état général. L’examen clinique ainsi que le bilan radiologique ont montré deux masses de la paroi thoracique et une atteinte parenchymateuse basale droite. L’examen anatomopathologique de la biopsie de la masse antérieure a montré des foyers d’actinomycose permettant d’établir le diagnostic d’actinomycose thoraco-pulmonaire. Un bilan immunologique s’est révélé normal. Le patient est alors mis sous traitement antibiotique à base d’amoxicilline protégée avec bonne évolution clinique et radiologique. Le but de cette observation est de rappeler les aspects radio-clinique, histologiques, thérapeutiques et évolutifs ainsi que les difficultés diagnostiques de cette affection. PMID:24672630

To describe a murine model of emphysema induced by a combination of exposure to cigarette smoke (CS) and instillation of porcine pancreatic elastase (PPE). A total of 38 C57BL/6 mice were randomly divided into four groups: control (one intranasal instillation of 0.9% saline solution); PPE (two intranasal instillations of PPE); CS (CS exposure for 60 days); and CS + PPE (two intranasal instillations of PPE + CS exposure for 60 days). At the end of the experimental protocol, all animals were anesthetized and tracheostomized for calculation of respiratory mechanics parameters. Subsequently, all animals were euthanized and their lungs were removed for measurement of the mean linear intercept (Lm) and determination of the numbers of cells that were immunoreactive to macrophage (MAC)-2 antigen, matrix metalloproteinase (MMP)-12, and glycosylated 91-kDa glycoprotein (gp91phox) in the distal lung parenchyma and peribronchial region. Although there were no differences among the four groups regarding the respiratory mechanics parameters assessed, there was an increase in the Lm in the CS + PPE group. The numbers of MAC-2-positive cells in the peribronchial region and distal lung parenchyma were higher in the CS + PPE group than in the other groups, as were the numbers of cells that were positive for MMP-12 and gp91phox, although only in the distal lung parenchyma. Our model of emphysema induced by a combination of PPE instillation and CS exposure results in a significant degree of parenchymal destruction in a shorter time frame than that employed in other models of CS-induced emphysema, reinforcing the importance of protease-antiprotease imbalance and oxidant-antioxidant imbalance in the pathogenesis of emphysema. Descrever um modelo murino de enfisema induzido por exposição a fumaça de cigarro (FC) e instilação de elastase pancreática porcina (EPP). Trinta e oito camundongos C57BL/6 foram aleatoriamente divididos em quatro grupos: controle (uma instilação intranasal de solução salina a 0,9%); EPP (duas instilações intranasais de EPP); FC (exposição a FC durante 60 dias) e FC + EPP (duas instilações intranasais de EPP + exposição a FC durante 60 dias). No fim do protocolo experimental, todos os animais foram anestesiados e traqueostomizados para o cálculo de parâmetros de mecânica respiratória. Em seguida, todos os animais foram sacrificados e seus pulmões foram removidos para a medição da intercepção linear média (Lm) e a determinação do número de células imunorreativas a antígeno macrofágico (MAC)-2, metaloproteinase da matriz (MMP)-12 e glicoproteína glicosilada de 91 kDa (gp91phox) no parênquima pulmonar distal e na região peribrônquica. Embora não tenha havido diferenças entre os quatro grupos quanto aos parâmetros de mecânica respiratória avaliados, houve aumento da Lm no grupo FC + EPP. O número de células positivas para MAC-2 na região peribrônquica e no parênquima pulmonar distal foi maior no grupo FC + EPP do que nos outros grupos, assim como o foi o número de células positivas para MMP-12 e gp91phox, porém somente no parênquima pulmonar distal. Nosso modelo de enfisema induzido por instilação de EPP e exposição a FC resulta em um grau significativo de destruição parenquimatosa em um período de tempo menor que o empregado em outros modelos de enfisema induzido por FC, o que reforça a importância do desequilíbrio entre proteases e antiproteases e entre oxidantes e antioxidantes na patogênese do enfisema.

Tuberculosis (TB) in humans is caused by members of the Mycobacterium tuberculosis complex (MTC). Rapid detection of the MTC is necessary for the timely initiation of antibiotic treatment, while differentiation between members of the complex may be important to guide the appropriate antibiotic treatment and provide epidemiological information. In this study, a multiplex real-time PCR diagnostics assay using novel molecular targets was designed to identify the MTC while simultaneously differentiating between M. tuberculosis and M. canettii. The lepA gene was targeted for the detection of members of the MTC, the wbbl1 gene was used for the differentiation of M. tuberculosis and M. canettii from the remainder of the complex, and a unique region of the M. canettii genome, a possible novel region of difference (RD), was targeted for the specific identification of M. canettii. The multiplex real-time PCR assay was tested using 125 bacterial strains (64 MTC isolates, 44 nontuberculosis mycobacteria [NTM], and 17 other bacteria). The assay was determined to be 100% specific for the mycobacteria tested. Limits of detection of 2.2, 2.17, and 0.73 cell equivalents were determined for M. tuberculosis/M. canettii, the MTC, and M. canettii, respectively, using probit regression analysis. Further validation of this diagnostics assay, using clinical samples, should demonstrate its potential for the rapid, accurate, and sensitive diagnosis of TB caused by M. tuberculosis, M. canettii, and the other members of the MTC.

To compare a once-daily long-acting β2 agonist (indacaterol 150 µg) with a once-daily long-acting anticholinergic (tiotropium 5 µg) in terms of their effects on exercise endurance (limit of tolerance, Tlim) in patients with moderate COPD. Secondary endpoints were their effects on lung hyperinflation, exercise-related dyspnea, and daily-life dyspnea. This was a randomized, single-blind, crossover pilot study involving 20 patients (mean age, 60.9 ± 10.0 years; mean FEV1, 69 ± 7% of predicted). Spirometric parameters, Transition Dyspnea Index scores, Tlim, and exertional dyspnea were compared after three weeks of each treatment (with a one-week washout period between treatments). Nineteen patients completed the study (one having been excluded because of COPD exacerbation). Improvement in Tlim from baseline tended to be greater after treatment with tiotropium than after treatment with indacaterol (96 ± 163 s vs. 8 ± 82 s; p = 0.06). Tlim significantly improved from baseline after treatment with tiotropium (having increased from 396 ± 319 s to 493 ± 347 s; p = 0.010) but not after treatment with indacaterol (having increased from 393 ± 246 to 401 ± 254 s; p = 0.678). There were no differences between the two treatments regarding improvements in Borg dyspnea scores and lung hyperinflation at "isotime" and peak exercise. There were also no significant differences between treatments regarding Transition Dyspnea Index scores (1.5 ± 2.1 vs. 0.9 ± 2.3; p = 0.39). In patients with moderate COPD, tiotropium tends to improve Tlim in comparison with indacaterol. No significant differences were observed between the two treatments regarding their effects on lung hyperinflation, exercise-related dyspnea, and daily-life dyspnea. Future studies, including a larger number of patients, are required in order to confirm our findings and explore mechanistic explanations. (ClinicalTrials.gov identifier: NCT01693003 [http://www.clinicaltrials.gov/]). Comparar um β2-agonista de longa duração administrado uma vez por dia (indacaterol 150 µg) a um anticolinérgico de longa duração administrado uma vez por dia (tiotrópio 5 µg) quanto a seus efeitos na resistência ao exercício (limite de tolerância, Tlim) em pacientes com DPOC moderada. Os desfechos secundários foram seus efeitos na hiperinsuflação pulmonar, na dispneia causada pelo exercício e na dispneia na vida diária. Estudo piloto randomizado cruzado e simples cego com 20 pacientes (média de idade: 60,9 ± 10,0 anos; média do VEF1: 69 ± 7% do previsto). Parâmetros espirométricos, pontuação no Transition Dyspnea Index, Tlim e dispneia aos esforços foram comparados após três semanas de cada tratamento (com uma semana de intervalo entre os tratamentos). Dezenove pacientes completaram o estudo - um foi excluído por causa de exacerbação da DPOC. A melhora no Tlim tendeu a ser maior com tiotrópio do que com indacaterol (96 ± 163 s vs. 8 ± 82 s; p = 0,06). Em comparação com os valores basais, o Tlim melhorou significativamente com tiotrópio (aumentando de 396 ± 319 s para 493 ± 347 s; p = 0,010), mas não com indacaterol (aumentando de 393 ± 246 para 401 ± 254 s; p = 0,678). Não houve diferença entre os tratamentos quanto à melhora na pontuação na escala de dispneia de Borg e na insuflação pulmonar no "isotempo" e no pico do exercício. Também não houve diferenças significativas entre os tratamentos quanto à pontuação no Transition Dyspnea Index (1,5 ± 2,1 vs. 0,9 ± 2,3; p = 0,39). Em pacientes com DPOC moderada, o tiotrópio tende a melhorar o Tlim em comparação com o indacaterol. Não houve diferenças significativas entre os tratamentos quanto a seus efeitos na insuflação pulmonar, na dispneia durante o exercício e na dispneia na vida diária. São necessários mais estudos, com um número maior de pacientes, para confirmar nossos achados e explorar explicações mecanicistas.

An international survey made in 1958, with the Comite"s Nationaux de Lutte Antituberculeuse, provided a large body of information gathered from Austria, Belgium, Canada, Denmark, France, Great Britain, Japan, Netherlands, Rumania, Switzerland, and Spain, relating to radiation dosages in detection of tuberculosis. It was found that in these countries with the equipment and techniques in use at the time, radiography necessitated a radiation dose of 200- 640 mr as measured on the dorsal surface of the thorax, whereas fluoroscopic examination required doses ranging from 700 mr to 15 r, according to technique employed. Gonadal doses were negligible with radiography, andmore » the significant genetic dose for the entire population was estimated to be not over 80 mu r in one country where approximately 55 million photofluorographic examinations were made in 1958 in persons under 30 years old. The average bone marrow dose per inhabitant varied from 0.2 to 37 mr in the various countries. Plumonary fluoroscopy exposes the individual to greater somatic and gonadic radiation and, it is suggested, should be eliminated from antituberculosis programs. To reduce patient exposure during thoracic radiology, the following precautions are recommended by the Commission de la Radiologie de l'Union Internationale contre la Tuberculose: use of mirror camera: adoption of higher film sensitivity and iniproved development techniques; use of higher maximum kilovoltage; establishment of a screen focus distance at less than 1 m; filtration with 3 mm of aluminum; exposure time of less than 1/10 sec; use of beam-localizing diaphragm and, if necessary, of a lead apron. Chest roentgenography still remains the most effective means for detecting new cases and follow-up examination in tuberculosis, and with adequate safeguards to minimize patient radiation, exposure does not present undue hazards.

Recent episodes of nosocomial tuberculosis, sometimes due to multiresistant strains, in HIV infected patients in the USA has led to the need for new prevention measures against the transmission of Mycobacterium tuberculosis in health care facilities. Tuberculosis is transmitted in Pflügge droplets generated when contagious persons cough. After drying, the droplets become aerosolized solid particles which are rapidly dispersed by air flow within the patient's room. People exposed to the same air are thus at high risk of being contaminated. If the air pressure in the patient's room is higher than the rest of the facility, the air coming form the room may contaminate personnel and other patients elsewhere in the facility. Infecting particles can be eliminated rapidly if the room air is ventilated outdoors. If the ventilation is strong enough so that air constantly circulates from the corridor into the room, infecting particles can no longer diffuse to the rest of the ward. It is also possible to use ultraviolet C light to disinfect the air, either within the room or within the ventilation system. These two basically simple systems are the fundamental environmental and prevention measures needed to limit tuberculosis spread in health care facilities. These methods are however technically complex, costly and require constant evaluation and maintenance by specialized personnel. In addition the potential side effects of ultraviolet waves could considerably reduce their application. These environmental methods, which are complementary methods, only have a meaning if the elementary measures for preventing the transmission of tuberculosis are correctly applied.(ABSTRACT TRUNCATED AT 250 WORDS)

Les tuberculomes intracrâniens représentent l'une des localisations les plus graves de la tuberculose, leur incidence varie en fonction du contexte représentant 0,2% des processus intracrâniens dans les pays occidentaux et 5 à 10% des masses intracrâniennes dans les pays en voie de développement. Nous rapportons une étude rétrospective de 125 cas. L'hypertension intracrânienne (45%) et le déficit neurologique (36%) sont les signes cliniques les plus fréquents. La lésion était localisée dans 60% des cas en sus-tentoriel et dans 40% des cas en sous-tentoriel. L'approche thérapeutique a consisté en un abord direct du tuberculome dans 67 cas (53%), une biopsie stéréotaxique dans 32 cas (25%), le traitement médical en première intention sans confirmation histologique dans 26 cas (20%). Avant 1993 notre service ne disposait pas de cadre de stéréotaxie, notre attitude thérapeutique consistait soit en un abord direct de la lésion dans 70% des cas, soit un traitement antituberculeux en première intention sans confirmation histologique (30%). Cette attitude était corrélée à une mortalité et morbidité non négligeables respectivement 3% et 10%. Après 1993; le taux d'abords direct a chuté a 38%, avec 47% de biopsies stéréotaxiques et seulement 13% des patients traités par antibacillaires sans preuve histologique. Ceci s'est accompagné d'une réduction significative de mortalité a 1,4% (p = 0,0003) et de morbidité a 2% (p = 0,0027). PMID:22937196

To evaluate the effects of passive inhalation of cigarette smoke on the respiratory system of guinea pigs. Male guinea pigs were divided into two groups: control and passive smoking, the latter being exposed to the smoke of ten cigarettes for 20 min in the morning, afternoon and evening (30 cigarettes/day) for five days. After that period, inflammatory parameters were studied by quantifying mesenteric mast cell degranulation, as well as oxidative stress, in BAL fluid. In addition, we determined MIP, MEP, and mucociliary transport (in vivo), as well as tracheal contractility response (in vitro). In comparison with the control group, the passive smoking group showed a significant increase in mast cell degranulation (19.75 ± 3.77% vs. 42.53 ± 0.42%; p < 0.001) and in the levels of reduced glutathione (293.9 ± 19.21 vs. 723.7 ± 67.43 nM/g of tissue; p < 0.05); as well as a significant reduction in mucociliary clearance (p < 0.05), which caused significant changes in pulmonary function (in MIP and MEP; p < 0.05 for both) and airway hyperreactivity. Passive inhalation of cigarette smoke caused significant increases in mast cell degranulation and oxidative stress. This inflammatory process seems to influence the decrease in mucociliary transport and to cause changes in pulmonary function, leading to tracheal hyperreactivity. Avaliar os efeitos da inalação passiva da fumaça de cigarro no sistema respiratório de cobaias. Foram utilizadas cobaias machos, divididas em dois grupos: controle e tabagismo passivo, esse último exposto à fumaça de dez cigarros por 20 min pela manhã, tarde e noite (30 cigarros/dia) por 5 dias. Após esse período, parâmetros inflamatórios foram estudados através da contagem de degranulação de mastócitos no mesentério e de estresse oxidativo a partir do LBA. Adicionalmente, foram verificadas PImáx, PEmáx, transporte mucociliar (in vivo) e contratilidade traqueal (in vitro). Na comparação com o grupo controle, o grupo tabagismo passivo apresentou um aumento significativo na degranulação de mastócitos (19,75 ± 3,77% vs. 42,53 ± 0,42%; p < 0,001), nos níveis de glutationa reduzida (293,9 ± 19,21 vs. 723,7 ± 67,43 nM/g de tecido; p < 0,05) e uma redução significativa no transporte mucociliar (p < 0,05), provocando alterações significativas na função pulmonar, tanto na PImáx como na PEmáx (p < 0,05 para ambas), e hiper-reatividade nas vias aéreas. A inalação passiva da fumaça de cigarro ocasionou aumentos significativos na degranulação de mastócitos e no estresse oxidativo. Esse processo inflamatório parece ter influenciado a diminuição do transporte mucociliar e causado alterações na função pulmonar, proporcionando um quadro de hiper-reatividade traqueal.

Lung and heart pathology in fatal drug addiction. A consecutive autopsy study.

Kringsholm, B; Christoffersen, P

1987-01-01

Lung and heart sections from 33 drug addicts submitted for medico-legal autopsy at the Institute of Forensic Medicine in Copenhagen were studied together with tissue sections from 20 'normal' persons. In the drug addict cases focal bleedings in lung tissue were found in 94%, signs of earlier bleedings, haemosiderin containing histiocytes, were seen in 91%, and focal fibrosis in 46%. The bleeding episodes may be due to hypoxia in connection with heroin intake. In 94% of the drug addicts birefringent material in lung tissue was demonstrated, in 58% in granulomas and giant cells, in 27% in giant cells only and in 9% in isolated histiocytes. The material was localized in the wall of pulmonar arteries and/or in the interstitial tissue, undoubtedly depending on the duration of the abuse. In 18% angiothrombosis was seen, in all cases granulomas/giant cells were observed in the wall of the vessel concerned. The results indicate periodical intravenous injection of dissolved tablets in addition to heroin. Histological signs of pulmonary hypertension were not seen, possibly due to the fact that abuse of central stimulants is very rare in Denmark. Regarding heart alterations no significant differences were demonstrated between drug addicts and controls. The only note-worthy finding was focal infiltration of lymphocytes in the atrio-ventricular bundle in two drug addicts, the meaning of which is uncertain.

The objective of this study was to describe the results of anatomic pulmonary resections performed by video-assisted thoracoscopy in Brazil. Thoracic surgeons (members of the Brazilian Society of Thoracic Surgery) were invited, via e-mail, to participate in the study. Eighteen surgeons participated in the project by providing us with retrospective databases containing information related to anatomic pulmonary resections performed by video-assisted thoracoscopy. Demographic, surgical, and postoperative data were collected with a standardized instrument, after which they were compiled and analyzed. The surgeons provided data related to a collective total of 786 patients (mean number of resections per surgeon, 43.6). However, 137 patients were excluded because some data were missing. Therefore, the study sample comprised 649 patients. The mean age of the patients was 61.7 years. Of the 649 patients, 295 (45.5%) were male. The majority-521 (89.8%)-had undergone surgery for neoplasia, which was most often classified as stage IA. The median duration of pleural drainage was 3 days, and the median hospital stay was 4 days. Of the 649 procedures evaluated, 598 (91.2%) were lobectomies. Conversion to thoracotomy was necessary in 30 cases (4.6%). Postoperative complications occurred in 124 patients (19.1%), the most common complications being pneumonia, prolonged air leaks, and atelectasis. The 30-day mortality rate was 2.0%, advanced age and diabetes being found to be predictors of mortality. Our analysis of this representative sample of patients undergoing pulmonary resection by video-assisted thoracoscopy in Brazil showed that the procedure is practicable and safe, as well as being comparable to those performed in other countries. O objetivo deste estudo foi descrever os resultados de ressecções pulmonares anatômicas por videotoracoscopia no Brasil. Cirurgiões torácicos (membros da Sociedade Brasileira de Cirurgia Torácica) foram convidados, por correio eletrônico, a participar do estudo. Dezoito cirurgiões participaram do projeto enviando seus bancos de dados retrospectivos referentes a ressecções anatômicas de pulmão por videotoracoscopia. Dados demográficos, cirúrgicos e pós-operatórios foram coletados em um instrumento padronizado e posteriormente compilados e analisados. Dados referentes a 786 pacientes foram encaminhados (média de 43,6 ressecções por cirurgião), sendo 137 excluídos por informações incompletas. Logo, 649 pacientes constituíram nossa população estudada. A média de idade dos pacientes foi de 61,7 anos, 295 eram homens (45,5%), e a maioria - 521 (89,8%) - foi submetida à cirurgia por neoplasia, mais frequentemente classificada como estádio IA. A mediana do tempo de drenagem pleural foi de 3 dias, e a do tempo de internação, 4 dias. Dos 649 procedimentos realizados, 598 (91,2%) foram lobectomias. A taxa de conversão para toracotomia foi de 4,6% (30 casos). Complicações pós-operatórias ocorreram em 124 pacientes (19,1%), sendo pneumonia, escape aéreo prolongado e atelectasia as mais frequentes. A mortalidade em 30 dias foi de 2,0%, tendo como preditores idade avançada e diabetes. A casuística brasileira mostra que as ressecções pulmonares por cirurgia torácica videoassistida são factíveis e seguras, além de comparáveis àquelas de registros internacionais.

Literature shows that patients undergoing hemodialysis present poor physical conditioning and low tolerance to exercise. They may also suffer from respiratory dysfunctions. The purpose of this study was to evaluate the effects of neuromuscular electrical stimulation on pulmonary function and functional capacity of patients with chronic kidney disease on hemodialysis. Forty adult patients with chronic kidney disease on hemodialysis were prospectively studied and randomized into two groups (control n = 20 and treatment n = 20). The treatment group underwent bilateral femoral quadriceps muscles electrical stimulation for 30 minutes during hemodialysis, three times per week, for two months. The patients were evaluated by pulmonary function test, maximum respiratory pressures, maximum one-repetition test, and six-minute walk test (6MWT), before and after the treatment protocol. The treatment group presented increased maximum inspiratory (MIP) (p = 0.02) and expiratory pressures (MEP) (p < 0.0001), muscular strength in maximum one-repetition test (p < 0.001), and distance covered in the 6MWT (p = 0.03), and decreased systolic blood pressure (p < 0.001) and respiratory frequency (p < 0.001) when compared with the control group. Electrical neuromuscular stimulation had a positive impact on pulmonary function and functional capacity, leading to better physical performance in patients on hemodialysis. Pacientes submetidos à hemodiálise apresentam baixo condicionamento físico além de serem acometidos por disfunções respiratórias. Objetivamos avaliar os efeitos da estimulação elétrica neuromuscular na função pulmonar e capacidade funcional de pacientes com doença renal crônica em hemodiálise. 40 adultos com doença renal crônica em hemodiálise foram estudados prospectivamente e randomizados em dois grupos (controle n = 20 e tratamento n = 20). O grupo tratamento realizou protocolo com estimulação elétrica neuromuscular em quadríceps femoral por 30 minutos durante a hemodiálise, três vezes por semana, durante dois meses. Todos pacientes realizaram espirometria, pressões respiratórias máximas, teste de uma repetição máxima e teste da caminhada dos seis minutos (TC6), antes e após o período de acompanhamento. O grupo tratamento apresentou aumento da pressão inspiratória máxima com p = 0,02 na comparação entre grupos e p < 0,001 para a pressão máxima expiratória. O teste de uma repetição máxima e a distância percorrida no TC6 apresentaram-se maiores após o protocolo no grupo de tratamento com p < 0,001 e 0,03 respectivamente. Houve diminuição da pressão arterial sistólica (p < 0,001) e frequência respiratória (p < 0,001) após a estimulação elétrica quando comparado ao grupo controle. A estimulação elétrica neuromuscular teve impacto positivo sobre a função pulmonar e a capacidade funcional levando ao melhor desempenho físico em pacientes em hemodiálise.

To use baseline audiogram parameters in order to ascertain whether drug-resistant tuberculosis (DR-TB) has effects on hearing, as well as to describe the configurations of the audiograms and to determine whether there are parameters that can be associated with those configurations. This was a prospective study involving patients diagnosed with DR-TB at a tuberculosis treatment center in the state of Ogun, in Nigeria. The patients included in the study were submitted to pure tone audiometry at baseline (within two weeks after treatment initiation). For comparative analyses, data regarding demographic and clinical characteristics were collected from the medical records of the patients. The final sample comprised 132 patients. The mean age of the patients was 34.5 ± 12.6 years (range, 8-82 years), and the male:female ratio was 2:1. Of the 132 patients, 103 (78.0%) resided in neighboring states, 125 (94.7%) had previously experienced antituberculosis treatment failure, and 18 (13.6%) were retroviral-positive. Normal audiograms were found in 12 patients (9.1%), whereas sensorineural hearing loss was identified in 104 (78.8%), the two most common configurations being ascending, in 54 (40.9%), and sloping, in 26 (19.7%). Pure-tone averages at low frequencies (0.25-1.0 kHz) and high frequencies (2.0-8.0 kHz) were 33.0 dB and 40.0 dB, respectively. Regarding the degree of hearing loss in the better ear, 36 patients (27.3%) were classified as having normal hearing and 67 (50.8%) were classified as having mild hearing loss (26-40 dB), whereas 29 (21.9%) showed moderate or severe hearing loss. Among the variables studied (age, gender, retroviral status, previous treatment outcome, and weight at admission), only male gender was associated with audiometric configurations. In this sample of patients with DR-TB, most presented with bilateral, mild, suboptimal sensorineural hearing loss, and ascending/sloping audiometric configurations were associated with male gender. Utilizar parâmetros do audiograma basal para verificar se a tuberculose resistente (TB-R) tem efeitos na audição, descrever as configurações dos audiogramas e determinar se há parâmetros que possam ser associados a essas configurações. Estudo prospectivo com pacientes diagnosticados com TB-R em um centro de tratamento de tuberculose no estado de Ogun, Nigéria. Os pacientes incluídos no estudo foram submetidos à audiometria de tons puros em até duas semanas após o início do tratamento (audiometria basal). Características demográficas e clínicas foram coletadas dos prontuários médicos dos pacientes para análises comparativas. A amostra final envolveu 132 pacientes. A média de idade dos pacientes foi de 34,5 ± 12,6 anos (variação, 8-82 anos), e a razão homem:mulher foi de 2:1. A maioria dos pacientes (n = 103; 78,0%) residia nos estados vizinhos e tinha história de falha de tratamento antituberculose (n = 125; 94.7%); 18 (13.6%) apresentavam status retroviral positivo. Doze pacientes (9,1%) apresentaram audiogramas normais, e 104 (78,8%) apresentaram perda auditiva neurossensorial, sendo as configurações mais comuns do tipo ascendente, em 54 (40,9%), e descendente, em 26 (19,7%). As médias de tons puros em frequências baixas (0,25-1,0 kHz) e altas (2,0-8,0 kHz) foram de 33,0 dB e 40,0 dB, respectivamente. Quanto ao grau de perda auditiva no melhor ouvido, 36 pacientes (27,3%) apresentaram audição normal, e 67 (50,8%) apresentaram perda auditiva leve (26-40 dB), enquanto 29 (21,9%) mostraram perda auditiva moderada ou grave. Entre as variáveis estudadas (idade, gênero, status retroviral, desfecho de tratamento anterior e peso na admissão), somente o gênero masculino foi associado às configurações audiométricas. Nesta amostra de pacientes com TB-R, a maioria apresentou perda auditiva neurossensorial leve e subótima bilateralmente, com configurações audiométricas ascendentes/descendentes associadas ao gênero masculino.

COPD is a major worldwide problem with a rising prevalence. Despite its importance, there is a lack of information regarding underdiagnosis and misdiagnosis of COPD in different countries. As part of the Proyecto Latinoamericano de Investigación en Obstrucción Pulmonar study, we examined the relationship between prior diagnostic label and airway obstruction in the metropolitan areas of five Latin American cities (São Paulo, Santiago, Mexico City, Montevideo, and Caracas). A two-stage sampling strategy was used in each of the five areas to obtain probability samples of adults aged >or= 40 years. Participants completed a questionnaire that included questions on prior diagnoses, and prebronchodilator and postbronchodilator spirometry. A study diagnosis of COPD was based on airway obstruction, defined as a postbronchodilator FEV(1)/FVC < 0.70. Valid spirometry and prior diagnosis information was obtained for 5,303 participants; 758 subjects had a study diagnosis of COPD, of which 672 cases (88.7%) had not been previously diagnosed. The prevalence of undiagnosed COPD was 12.7%, ranging from 6.9% in Mexico City to 18.2% in Montevideo. Among 237 subjects with a prior COPD diagnosis, only 86 subjects (36.3%) had postbronchodilator FEV(1)/FVC < 0.7, while 151 subjects (63.7%) had normal spirometric values. In the same group of 237 subjects, only 34% reported ever undergoing spirometry prior to our study. Inaccurate diagnostic labeling of COPD represents an important health problem in Latin America. One possible explanation is the low rate of spirometry for COPD diagnosis.

Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by precapillary pulmonary hypertension secondary to vaso-occlusive pulmonary vasculopathy and is classified as Pulmonary Hypertension Group 4. The aim of this study is to report the clinical experience of CTEPH in Mexico. Consecutive patients diagnosed with CTEPH were identified from the Registro de Pacientes con Hipertension Pulmonar del Instituto de Seguridad y Servicio Social de los Trabajadores del Estado (REPHPISSSTE) registry between January 2009 and February 2014. Right heart catheterization was not routinely performed prior to August 2010 in the work-up of CTEPH. We identified 50 patients with CTEPH; their median age was 63 years and 58 % were female. Patients had multiple associated co-morbidities and moderate hemodynamic impairment. All patients were treated with anticoagulation. Despite surgical evaluation for pulmonary endarterectomy (PEA), only one patient underwent PEA given the lack of infrastructure for post-operative care and lack of insurance for this procedure. Most of the patients were treated with sildenafil, bosentan, or both, with increasing use of rivaroxaban and sildenafil in recent years. The overall survival of the cohort was similar to that reported in other international registries, despite the limitations of care imposed by drug availability and surgical feasibility. This is the first report on the CTEPH experience in Mexico. It highlights the similarity of patients in the REPHPISSSTE registry to those in international registries as well as the challenges that clinicians face in a resource-limited setting.

[The boycott against German scientists and the German language after World War I].

PubMed

Reinbothe, R

2013-12-01

After the First World War, the Allied academies of sciences staged a boycott against German scientists and the German language. The objective of the boycott was to prevent the re-establishment of the prewar dominance of German scientists, the German language and German publications in the area of international scientific cooperation. Therefore the Allies excluded German scientists and the German language from international associations, congresses and publications, while they created new international scientific organizations under their leadership. Medical associations and congresses were also affected, e. g. congresses on surgery, ophthalmology and tuberculosis. Allied physicians replaced the "International Anti-Tuberculosis Association" founded in Berlin in 1902 with the "Union Internationale contre la Tuberculose"/"International Union against Tuberculosis", founded in Paris in 1920. Only French and English were used as the official languages of the new scientific organizations, just as in the League of Nations. The boycott was based on the fact that the German scientists had denied German war guilt and war crimes and glorified German militarism in a manifesto "To The Civilized World!" in 1914. The boycott first started in 1919 and had to be abolished in 1926, when Germany became a member of the League of Nations. Many German and foreign physicians as well as other scientists protested against the boycott. Some German scientists and institutions even staged a counter-boycott impeding the resumption of international collaboration. The boycott entailed an enduring decline of German as an international scientific language. After the Second World War scientists of the victorious Western Powers implemented a complete reorganization of the international scientific arena, based on the same organizational structures and language restrictions they had built up in 1919/1920. At the same time scientists from the U.S.A. staged an active language and publication policy, in order to establish the dominance of English in the international scientific arena. © Georg Thieme Verlag KG Stuttgart · New York.

ABSTRACT OBJECTIVE To analyze the prevalence and factors associated with multidrug-resistant tuberculosis in Espírito Santo, Brazil. METHODS This is a cross-sectional study of cases of tuberculosis tested for first-line drugs (isoniazid, rifampicin, pyrazinamide, ethambutol, and streptomycin) in Espírito Santo between 2002 and 2012. We have used laboratory data and registration of cases of tuberculosis – from the Sistema Nacional de Agravos de Notificação and Sistema para Tratamentos Especiais de Tuberculose. Individuals have been classified as resistant and non-resistant and compared in relation to the sociodemographic, clinical, and epidemiological variables. Some variables have been included in a logistic regression model to establish the factors associated with resistance. RESULTS In the study period, 1,669 individuals underwent anti-tuberculosis drug susceptibility testing. Of these individuals, 10.6% showed resistance to any anti-tuberculosis drug. The rate of multidrug resistance observed, that is, to rifampicin and isoniazid, has been 5%. After multiple analysis, we have identified as independent factors associated with resistant tuberculosis: history of previous treatment of tuberculosis [recurrence (OR = 7.72; 95%CI 4.24–14.05) and re-entry after abandonment (OR = 3.91; 95%CI 1.81–8.43)], smoking (OR = 3.93; 95%CI 1.98–7.79), and positive culture for Mycobacterium tuberculosis at the time of notification of the case (OR = 3.22; 95%CI 1.15–8.99). CONCLUSIONS The partnership between tuberculosis control programs and health teams working in the network of Primary Health Care needs to be strengthened. This would allow the identification and monitoring of individuals with a history of previous treatment of tuberculosis and smoking. Moreover, the expansion of the offer of the culture of tuberculosis and anti-tuberculosis drug susceptibility testing would provide greater diagnostic capacity for the resistant types in Espírito Santo.

Les sacro-iliites infectieuses méritent d’être mieux connues. Leur diagnostic est souvent retardé en raison d'une symptomatologie trompeuse et des diffcultés d'exploration de l'articulation sacro-iliaque. Notre travail est basé sur une étude rétrospective portant sur les cas de SII, recueillis sur une période comprise entre 1997 et 2008 dans notre centre universitaire Sfax-Tunisie. Le diagnostic de sacro-iliite était retenu en présence d'arguments cliniques et radiologiques d'atteinte sacroiliaque. Nous rapportons dix neuf cas de sacroiliites infectieuses (10 hommes et 9 femmes), avec un âge moyen de 32 ans. L'atteinte était unilatérale dans tous les cas. Les radiographies standard faites dans tous les cas ont été suggestives dans 14 cas et normales dans les autres cas. La TDM faite dans 13 cas a montré, un abcès des parties molles dans 8 cas et un séquestre osseux dans 2 cas. L'IRM réalisée dans 8 cas, a objectivé une infiltration des parties molles dans tous les cas et un abcès dans 3 cas. Le germe a été identifié dans 9 cas (3 cas de tuberculose, 3 cas de brucellose, 2 sacro-iliites à pyogène et un cas de candidose). Cette identification était faite par biopsie dans 3 cas, hémocultures dans 2 cas, prélèvement au niveau de la porte d'entrée dans 1 cas et sérodiagnostic dans 3 cas. Pour les autres cas, l'origine pyogène a été retenue sur des arguments cliniques et biologiques. L'imagerie joue un rôle primordial dans le diagnostic précoce et l'orientation étiologique d'une sacroiliite infectieuse. PMID:25120884

Les complications infectieuses sont redoutables au cours de la polyarthrite rhumatoïde (PR). Le but de notre étude est d'estimer leur fréquence et de déterminer les facteurs associés à l'infection chez ces patients. Il s'agit d'une étude rétrospective incluant les cas de PR établis recensés entre 2007 et 2011 au service de rhumatologie au CHU Hassan II de Fès au Maroc. Nous avons inclu 164 patients atteint de PR, l’âge moyen des patients était de 47,9 ans, avec une prédominance féminine (137 F/27H). La fréquence des infections dans notre série était de 26,2%, dominées par les infections urogénitales (22 cas), pleuro pulmonaires (11 cas) dont 2 cas de tuberculose pulmonaire et un cas d'infection H1N1, 3 cas d'infections cutanées et 4 cas d'arthrite septiques. Dans notre série 127 patients étaient sous corticothérapie orale, 147 patients étaient sous méthotrexate, 25 patients étaient sous rituximab et 8 patients étaient sous tocilizumab. Dans notre étude, les facteurs associés à la survenue d'infection étaient l’âge avancé (p= 0,02), une CRP élevée (p= 0,04) et une dose de corticothérapie - 7.5 mg/j (p= 0,03). Notre étude a mis en évidence certains facteurs associés à la survenue d'une infection au cours de la PR. En connaissant ces facteurs, il faut instaurer une surveillance particulière pour améliorer la qualité de prise en charge. PMID:25120853

Stage I: Hilar Adenopathy With normal lung function observe, as it often resolves. With reduced lung function observe for 6-12 months. Treat if there is progression or persistence. With erythema nodosum use mild anti-inflammatory agents such as salicylates or like drugs. Stage II: Adenopathy + Pulmonar Infiltrates With normal or slightly reduced lung function observe; treat if it worsens. Treat if there is no remission in 6-12 months. With reduced lung function treat, possibly for many years or a lifetime. Stage III: Pulmonary Infiltrates +/- Fibrosis Without Adenopathy There is reduced lung function. Treat, demonstrate improvement, follow patients with serial measurements of vital capacity at least. Other Indications for Treatment Other indications for treatment include myocardial sarcoidosis, cerebral sarcoidosis (although the outcome is less certain), serious hepatic or renal sarcoidosis, hypercalcemia, persistent systemic symptoms, or other serious organ or functional impairment. Assess each patient individually and completely. Use good clinical judgement. It is clear that treatment that is too little or too late is of little benefit. Even the statistical results form a perfectly controlled study cannot provide absolute direction for the individual patient. As clinicians we are frequently called upon to apply considered judgements without hard data to predict the outcome. We also maintain the flexibility to change our therapeutic programs when circumstances change, either in the patient or in our knowledge. We can be grateful we have a treatment as good as corticosteroids and must try to exercise our best judgement as to when it should be instituted.

To evaluate the influence of chronic heart failure (CHF) on resting lung volumes in patients with COPD, i.e., inspiratory fraction-inspiratory capacity (IC)/TLC-and relative inspiratory reserve-[1 - (end-inspiratory lung volume/TLC)]. This was a prospective study involving 56 patients with COPD-24 (23 males/1 female) with COPD+CHF and 32 (28 males/4 females) with COPD only-who, after careful clinical stabilization, underwent spirometry (with forced and slow maneuvers) and whole-body plethysmography. Although FEV1, as well as the FEV1/FVC and FEV1/slow vital capacity ratios, were higher in the COPD+CHF group than in the COPD group, all major "static" volumes-RV, functional residual capacity (FRC), and TLC-were lower in the former group (p < 0.05). There was a greater reduction in FRC than in RV, resulting in the expiratory reserve volume being lower in the COPD+CHF group than in the COPD group. There were relatively proportional reductions in FRC and TLC in the two groups; therefore, IC was also comparable. Consequently, the inspiratory fraction was higher in the COPD+CHF group than in the COPD group (0.42 ± 0.10 vs. 0.36 ± 0.10; p < 0.05). Although the tidal volume/IC ratio was higher in the COPD+CHF group, the relative inspiratory reserve was remarkably similar between the two groups (0.35 ± 0.09 vs. 0.44 ± 0.14; p < 0.05). Despite the restrictive effects of CHF, patients with COPD+CHF have relatively higher inspiratory limits (a greater inspiratory fraction). However, those patients use only a part of those limits, probably in order to avoid critical reductions in inspiratory reserve and increases in elastic recoil. Avaliar a influência da insuficiência cardíaca crônica (ICC) nos volumes pulmonares de repouso em pacientes com DPOC, ou seja, fração inspiratória -capacidade inspiratória (CI)/CPT - e reserva inspiratória relativa - [1 - (volume pulmonar inspiratório final/CPT)]. Após cuidadosa estabilização clínica, 56 pacientes com DPOC (24 alocados no grupo DPOC+ICC; 23 homens/1 mulher) e 32 (28 homens/4 mulheres) com DPOC isolada foram submetidos à espirometria forçada e lenta e pletismografia de corpo inteiro. Os pacientes do grupo DPOC+ICC apresentaram maior VEF1, VEF1/CVF e VEF1/capacidade vital lenta; porém, todos os principais volumes "estáticos" - VR, capacidade residual funcional (CRF) e CPT - foram menores que aqueles do grupo DPOC (p < 0,05). A CRF diminuiu mais do que o VR, determinando assim menor volume de reserva expiratória no grupo DPOC+ICC que no grupo DPOC. Houve redução relativamente proporcional da CRF e da CPT nos dois grupos; logo, a CI também foi similar. Consequentemente, a fração inspiratória no grupo DPOC+ICC foi maior que no grupo DPOC (0,42 ± 0,10 vs. 0,36 ± 0,10; p < 0,05). Embora a razão volume corrente/CI fosse maior no grupo DPOC+ICC, a reserva inspiratória relativa foi notadamente similar entre os grupos (0,35 ± 0,09 vs. 0,44 ± 0,14; p < 0,05). Apesar dos efeitos restritivos da ICC, pacientes com DPOC+ICC apresentam elevações relativas dos limites inspiratórios (maior fração inspiratória). Entretanto, esses pacientes utilizam apenas parte desses limites, com o provável intuito de evitar reduções críticas da reserva inspiratória e maior trabalho elástico.

La symptomatologie clinique est la douleur thoracique (92%), la dyspnée (60%). Et sur la radiographie thoracique: on trouve un PNO (pneumothorax) unilatéral total (110 cas); partiel (10 cas); localisé (6 cas); bilatéral (4 cas); à droite dans 51,4% et à gauche dans 45,7%. On a recensé 70% de pneumothorax spontanés primitifs et 30% de PNO secondaire à (BPCO 44%, et tuberculose pulmonaire 39%). La prise en charge initiale est l’hospitalisation de tous les patients : le drainage thoracique (95%), l’exsufflation à l’aiguille (1%). Le repos et l’O2 (4%). Le retour du poumon à la paroi a été obtenu avant 10 jours chez 63%. L’évolution est favorable chez 89%. Et les complications immédiates: l’emphysème sous cutané (5 cas); une infection (6 cas) et 3 décès (arrêt cardio-respiratoire); les complications à distance sont les récidives dans 11,6%; une 1ère récidive chez 13 cas (drainage thoracique chez 11 cas et oxygénothérapie chez 2 cas) et une 2ème récidive chez 3 cas (recours à la chirurgie). Ce travail montre l’intérêt du drainage thoracique et la surveillance dans la prise en charge du pneumothorax pour éviter les complications et surtout pour éviter les récidives avec un éventuel recours à la chirurgie.

We have studied whether hyperbaric oxygen (HBO) prevents different pulmonary aspiration materials-induced lung injury in rats. The experiments were designed in 60 Sprague-Dawley rats, ranging in weight from 250 to 300 g, randomly allotted into one of six groups (n = 10): saline control, Biosorb Energy Plus (BIO), hydrochloric acid (HCl), saline + HBO treated, BIO + HBO treated, and HCl + HBO treated. Saline, BIO, HCl were injected into the lungs in a volume of 2 ml/kg. A total of seven HBO sessions were performed at 2,4 atm 100% oxygen for 90 min at 6-h intervals. Seven days later, rats were sacrificed, and both lungs in all groups were examined biochemically and histopathologically. Our findings show that HBO inhibits the inflammatory response reducing significantly (P < 0.05) peribronchial inflammatory cell infiltration, alveolar septal infiltration, alveolar edema, alveolar exudate, alveolar histiocytes, interstitial fibrosis, granuloma, and necrosis formation in different pulmonary aspiration models. Pulmonar aspiration significantly increased the tissue HP content, malondialdehyde (MDA) levels and decreased (P < 0.05) the antioxidant enzyme (SOD, GSH-Px) activities. HBO treatment significantly (P < 0.05) decreased the elevated tissue HP content, and MDA levels and prevented inhibition of SOD, and GSH-Px (P < 0.05) enzymes in the tissues. Furthermore, there is a significant reduction in the activity of inducible nitric oxide synthase, TUNEL and arise in the expression of surfactant protein D in lung tissue of different pulmonary aspiration models with HBO therapy. It was concluded that HBO treatment might be beneficial in lung injury, therefore, shows potential for clinical use.

El objetivo del presente trabajo fue analizar la situación epidemiológica de la tuberculosis (TB) en la Región Sanitaria V (RSV), provincia de Buenos Aires. El estudio de tendencia permitió conocer un valor promedio de las variaciones de la tasa de incidencia (TI), calculadas por regresión lineal simple y expresadas como variación anual promedio (VAP). Se analizaron el número de casos notificados y TI por 100 000 habitantes de todas las formas de TB, los casos de TB pulmonar (TBP) y TBP confirmados por bacteriología, total casos por grupos de edad: 0 – 14; 15 – 29 y mayores de 64 años, entre el 1° de enero de 2000 al 31 de diciembre de 2011. La declinación de la TI fue menor al 5% para todas las formas de TB e inferior en las TBP confirmadas bacteriológicamente. Los casos de TBP y TI más elevadas, se concentraron en el grupo de 15 a 29 años, con tendencia estable o ligeramente ascendente de la TI en la TBP bacilífera. El mismo comportamiento presentaron los casos de TBP infantil con confirmación bacteriológica. La mayor velocidad de descenso en la TI de la TBP se produjo en este grupo de edad, mientras que en mayores de 64 años, el descenso fue sostenido en el tiempo. La TB persiste como un riesgo de salud en la RSV, con casos en edades jóvenes, por lo que sigue siendo necesario fortalecer el control de la TB en esta región. PMID:26117604

Is necessary to develop models for the study of leptospirosis. To genotype a Colombian strain of Leptospira isolated from a human with Weil´s syndrome and to evaluate its infection dynamics in the hamster experimental model. Genotyping was performed by amplification and sequence analysis of the rrs 16S and lipL32 genes. The median lethal dose was determined in intraperitoneally inoculated hamsters. The patterns of clinical chemistry, the duration of leptospiremia, leptospiruria and pathological findings were studied and compared in the same animal model infected with L. interrogans (Fiocruz L1-130). Molecular typing revealed that the isolate corresponded to the pathogenic species L. santarosai, which was recovered from hamsters´ kidneys and lungs and detected by lipL32 PCR from day 3 post-infection in these organs. There was a marked increase of C-reactive protein in animals at day 5 post-infection (3.25 mg/dl; normal value: 0.3 mg/dl) with decreases by day 18 (2.60 mg/dl: normal value: 0.8 mg/dl). Biomarkers of urea showed changes consistent with possible renal acute failure (day 5 post-infection: 49.01 mg/dl and day 18 post-infection: 53.71 mg/dl). Histopathological changes included interstitial pneumonia with varying degrees of hemorrhage and interstitial nephritis. The pathogenic species L. santarosai was identified in Colombia. Its pathogenicity as determined by tropism to lung and kidney was comparable to that of L. interrogans Fiocruz L1-130, well known for its virulence and pulmonar tropism. The biological aspects studied here had never before been evaluated in an autochthonous isolate.

Recurrent exacerbations are common in COPD patients. Limited information exists regarding exacerbation frequency in COPD patients from epidemiologic studies. We examined the frequency of self-reported exacerbations and the factors influencing exacerbation frequency among COPD patients in a population-based study conducted in Latin America. We used a post-bronchodilator FEV(1)/FVC ratio of < 0.70 to define COPD. Exacerbation was self-reported and defined by symptoms (deterioration of breathing symptoms that affected usual daily activities or caused missed work). Spirometry was performed in 5,314 subjects. There were 759 subjects with airflow limitation; of these, 18.2% reported ever having had an exacerbation, 7.9% reported having an exacerbation, and 6.2% reported having an exacerbation requiring at least a doctor visit within the past year. The proportion of individuals with an exacerbation significantly increased by Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages, from 4.2% in stage 1 to 28.9% in stages 3 and 4. The self-reported exacerbation rate was 0.58 exacerbations per year. The rate of exacerbations requiring at least a doctor visit and length of stay in hospital due to exacerbations also increased as COPD severity progressed. The factors associated with having an exacerbation in the past year were dyspnea, prior asthma diagnosis, receiving any respiratory therapy, and disease severity of GOLD stages 3 and 4. The proportion of individuals with airflow limitation and self-reported exacerbation increases as the disease severity progresses. Dyspnea, prior asthma diagnosis, receiving any respiratory therapy, and more severe obstruction were significantly associated with having an exacerbation in the past year.

El Mal Agudo de Montaña (MAM) es un conjunto de síntomas inespecíficos padecidos por sujetos que ascienden rápidamente desde baja a alta altura sin adecuada aclimatación. Usualmente es autolimitado, pero las formas graves (edema pulmonar y cerebral) pueden causar la muerte. La hipoxemia exagerada en reposo está relacionada con el desarrollo de MAM pero su valor predictivo es limitado. Dado que el ejercicio en altura se acompaña de mayor hipoxemia y síntomas, postulamos el valor predictivo de un simple test de ejercicio para pronosticar MAM grave. Se estudió el valor predictivo de la saturación de oxígeno en reposo y ejercicio submáximo a 2 700m y 4 300m en 63 sujetos que ascendían al cerro Aconcagua (6 962m). Se consideró desaturación de oxígeno con ejercicio a una disminución >=5% respecto al reposo. Se utilizó la escala de Lake-Louise para establecer la presencia de MAM grave. 6 sujetos presentaron MAM grave (9.5%) y requirieron evacuación. La saturación de oxígeno en reposo a 2 700m no fue significativa para clasificar sujetos que luego desarrollaron MAM grave. Por el contrario, la asociación de desaturación durante el ejercicio a 2 700m más la saturación inapropiada en reposo a 4 300m fue significativa para clasificar a los sujetos que desarrollaron MAM grave con un valor predictivo positivo de 80% y un valor predictivo negativo del 97%. Nuestros resultados son relevantes para el montañismo y sugieren la adición de un simple test de ejercicio en la predicción del MAM grave. PMID:20228017

Patients with chronic obstructive pulmonary disease (COPD) usually complain of symptoms such as cough, sputum, wheezing, and dyspnea. Little is known about clinical symptoms in individuals with restrictive ventilatory impairment. The aim of this study was to compare the prevalence and type of respiratory symptoms in patients with COPD to those reported by individuals with restrictive ventilatory impairment in the Proyecto Latinoamericano de Investigacion en Obstruccion Pulmonar study. Between 2002 and 2004, individuals ≥40 years of age from five cities in Latin America performed pre and post-bronchodilator spirometry and had their respiratory symptoms recorded in a standardized questionnaire. Among the 5315 individuals evaluated, 260 (5.1%) had a restrictive spirometric diagnosis (forced vital capacity (FVC) < lower limit of normal (LLN) with forced expiratory volume in the first second to forced vital capacity ratio (FEV1/FVC) ≥ LLN; American Thoracic Society (ATS)/European Respiratory Society (ERS) 2005) and 610 (11.9%) were diagnosed with an obstructive pattern (FEV1/FVC < LLN; ATS/ERS 2005). Patients with mild restriction wheezed more ((30.8%) vs. (17.8%); p < 0.028). No difference was seen in dyspnea, cough, and sputum between the two groups after adjusting for severity stage. The health status scores for the short form 12 questionnaire were similar in restricted and obstructed patients for both physical (48.4 ± 9.4 vs. 48.3 ± 9.8) and mental (50.8 ± 10.6 vs. 50.0 ± 11.5) domains. Overall, respiratory symptoms are not frequently reported by patients with restricted and obstructed patterns as defined by spirometry. Wheezing was more frequent in patients with restricted pattern compared with those with obstructive ventilatory defect. However, the prevalence of cough, sputum production, and dyspnea are not different between the two groups when adjusted by the same severity stage. © The Author(s) 2015.

In patients with severe respiratory failure, either hypoxemic or hypercapnic, life support with mechanical ventilation alone can be insufficient to meet their needs, especially if one tries to avoid ventilator settings that can cause injury to the lungs. In those patients, extracorporeal membrane oxygenation (ECMO), which is also very effective in removing carbon dioxide from the blood, can provide life support, allowing the application of protective lung ventilation. In this review article, we aim to explore some of the most relevant aspects of using ECMO for respiratory support. We discuss the history of respiratory support using ECMO in adults, as well as the clinical evidence; costs; indications; installation of the equipment; ventilator settings; daily care of the patient and the system; common troubleshooting; weaning; and discontinuation. RESUMO Em pacientes com insuficiência respiratória grave (hipoxêmica ou hipercápnica), o suporte somente com ventilação mecânica pode ser insuficiente para suas necessidades, especialmente quando se tenta evitar o uso de parâmetros ventilatórios que possam causar danos aos pulmões. Nesses pacientes, extracorporeal membrane oxygenation (ECMO, oxigenação extracorpórea por membrana), que também é muito eficaz na remoção de dióxido de carbono do sangue, pode manter a vida, permitindo o uso de ventilação pulmonar protetora. No presente artigo de revisão, objetivamos explorar alguns dos aspectos mais relevantes do suporte respiratório por ECMO. Discutimos a história do suporte respiratório por ECMO em adultos; evidências clínicas; custos; indicações; instalação do equipamento; parâmetros ventilatórios; cuidado diário do paciente e do sistema; solução de problemas comuns; desmame e descontinuação.

INTRODUCCIONEl derrame pleural neoplásico (DPN) implica una enfermedad oncológica avanzada. La biopsia pleural por cirugía torácica endoscópica permite el diagnóstico en más del 90% de los casos y la instrumentación del espacio pleural complicado, mejorando los resultados de la técnica.MATERIAL Y METODOSe realizó un análisis retrospectivo de pacientes con DPN operados para la realización de una pleurodesis química con talco. Se formaron dos grupos, uno con derrame pleural neoplásico complicado (DPNC) y otro con derrame pleural neoplásico no complicado (DPNNC). En el grupo con DPNC se realizó "maniobras de liberación - expansión". Se compararon las variables entre ambos grupos para el análisis pertinente.RESULTADOSSe analizaron 28 pacientes con DPN tratados con pleurodesis química por cirugía torácica endoscópica. La edad promedio fue de 62,64 años. El compromiso pleural por patología mamaria fue la forma más frecuente (46,4%). No se hubo diferencia en cuanto a complicaciones (p= 0,31) y riesgo de defunción a los 30 días (p=1,09) con el manejo agresivo del espacio pleural. La demora en la indicación de pleurodesis se relacionó con un mayor índice de complicaciones (p=0,002) y mayor probabilidad de defunción dentro de los 30 días (p=0,008). La mayoría de pacientes se reinsertó a sus tareas diarias, con buena tolerancia a la disnea luego del procedimiento.  CONCLUSIONEn los pacientes con DPNC, las "maniobras de liberación - expansión pulmonar" descriptas, aumentarían las chances de mejorar los resultados con bajo riesgo. La pleurodesis química temprana mejora la calidad de vida de los pacientes portadores de un DPN.

OBJECTIVE: To determine the underdiagnosis rate in new COPD cases at the end of a nine-year follow-up period-in the study designated "Projeto Latino-Americano de Investigação em Obstrução Pulmonar" (PLATINO, Latin-American Pulmonary Obstruction Investigation Project)-and compare that with the underdiagnosis rate during the initial phase of the study, as well as to identify the clinical features exhibited by the subjects who were not diagnosed until the end of the follow-up phase. METHODS: The study population comprised the 1,000 residents of the city of São Paulo, Brazil, who took part in the PLATINO study. Of those, 613 participated in the follow-up phase, during which the subjects were assessed with the same instruments and equipment employed in the initial phase of the study. We used the chi-square test or the independent sample t-test to analyze the underdiagnosis rate and to identify the characteristics of the subjects who were not diagnosed until the end of the follow-up phase. RESULTS: The underdiagnosis rate for new COPD cases at the end of the nine-year follow-up period was 70.0%. The underdiagnosis rate during the follow-up phase was 17.5% lower than that reported for the initial phase of the study. The subjects who were not diagnosed until the end of the follow-up phase presented with fewer respiratory symptoms, better pulmonary function, and less severe disease than did those previously diagnosed with COPD. CONCLUSIONS: The underdiagnosis rate for new COPD cases was lower in the follow-up phase of the study than in the initial phase. The subjects who were not diagnosed until the end of the follow-up phase of the PLATINO study presented with the same clinical profile as did those who were not diagnosed in the initial phase. These findings underscore the need for spirometry in order to confirm the diagnosis of COPD and provide early intervention. PMID:24626267

The Esx and PE/PPE families of proteins are among the most immunodominant mycobacterial antigens and have thus been the focus of research to develop vaccines and immunological tests for diagnosis of bovine and human tuberculosis, mainly caused by Mycobacterium bovis and Mycobacterium tuberculosis, respectively. In non-tuberculous mycobacteria (NTM), multiple copies of genes encoding homologous proteins have mainly been identified in pathogenic Mycobacterium species phylogenically related to Mycobacterium tuberculosis and Mycobacterium bovis. Only ancestral copies of these genes have been identified in nonpathogenic NTM species like Mycobacterium smegmatis, Mycobacterium sp. KMS, Mycobacterium sp. MCS, and Mycobacterium sp. JLS. In this study we elucidated the genomes of four nonpathogenic NTM species, viz Mycobacterium komanii sp. nov., Mycobacterium malmesburii sp. nov., Mycobacterium nonchromogenicum, and Mycobacterium fortuitum ATCC 6841. These genomes were investigated for genes encoding for the Esx and PE/PPE (situated in the esx cluster) family of proteins as well as adjacent genes situated in the ESX-1 to ESX-5 regions. To identify proteins actually expressed, comparative proteomic analyses of purified protein derivatives from three of the NTM as well as Mycobacterium kansasii ATCC 12478 and the commercially available purified protein derivatives from Mycobacterium bovis and Mycobacterium avium was performed. The genomic analysis revealed the occurrence in each of the four NTM, orthologs of the genes encoding for the Esx family, the PE and PPE family proteins in M. bovis and M. tuberculosis. The identification of genes of the ESX-1, ESX-3, and ESX-4 region including esxA, esxB, ppe68, pe5, and pe35 adds to earlier reports of these genes in nonpathogenic NTM like M. smegmatis, Mycobacterium sp. JLS and Mycobacterium KMS. This report is also the first to identify esxN gene situated within the ESX-5 locus in M. nonchromogenicum. Our proteomics analysis identified a total of 609 proteins in the six PPDs and 22 of these were identified as shared between PPD of M.bovis and one or more of the NTM PPDs. Previously characterized M tuberculosis/M. bovis homologous immunogenic proteins detected in one or more of the nonpathogenic NTM in this study included CFP-10 (detected in M. malmesburii sp. nov. PPD), GroES (detected in all NTM PPDs but M. malmesburii sp. nov.), DnaK (detected in all NTM PPDs), and GroEL (detected in all NTM PPDs). This study confirms reports that the ESX-1, ESX-3, and ESX-4 regions are ancestral regions and thus found in the genomes of most mycobacteria. Identification of NTM homologs of immunogenic proteins warrants further investigation of their ability to cause cross-reactive immune responses with MTBC antigens.

Multidrug-resistant tuberculosis (MDR-TB) is a serious public health problem, but the new drugs bedaquiline (BDQ) and delamanid offer hope to improve outcomes and minimise toxicity. In Khayelitsha, South Africa, patients are routinely started on BDQ in the out-patient setting. This report from the field describes BDQ use in the out-patient setting at the Nolungile Clinic. The clinic staff overall report a positive experience using the drug. Challenges have been based largely on the logistics of drug supply and delivery. BDQ can be started successfully in the out-patient setting, and can be a positive experience for both patients and providers. La tuberculose multirésistante (TB-MDR) est un problème de santé publique grave, mais les nouveaux médicaments que sont la bédaquiline (BDQ) et le délamanide apportent un espoir d'améliorer les résultats tout en réduisant la toxicité. A Khayelitsha, Afrique du Sud, les patients démarrent leur traitement par BDQ en consultation externe en routine. Ce rapport du terrain décrit l'utilisation de la BDQ à la consultation externe du dispensaire Nolungile. Dans l'ensemble, le personnel du centre de santé exprime une expérience positive du médicament. Les défis ont surtout été liés à la logistique de l'approvisionnement et de la distribution du médicament. La BDQ peut être mise en route avec succès dans le cadre d'une consultation externe et peut constituer une expérience positive pour les patients et les prestataires de soins. La tuberculosis multirresistente (TB-MDR) representa un grave problema de salud pública, pero la utilización de nuevos medicamentos como la bedaquilina (BDQ) y el delamanid ofrece perspectivas de mejores desenlaces terapéuticos y disminución de la toxicidad asociada. En Khayelitsha, Suráfrica, se inicia de manera sistemática el tratamiento ambulatorio con BDQ. En el presente informe del terreno, se describe la utilización de BDQ en tratamiento antituberculoso ambulatorio en el centro de atención Nolungile. En general, los miembros del personal del centro refirieron una experiencia positiva con la administración del medicamento. Las dificultades surgieron en gran parte con respecto a aspectos logísticos del suministro y la administración del medicamento. Es posible iniciar un tratamiento eficaz con BDQ en condiciones ambulatorias, y represente una experiencia positiva para los pacientes y los profesionales de salud.

To explore the clinical effects of posterior debridement, bone grafting via intervertebral space combined with internal fixation for the treatment of lumbosacral tuberculosis. The clinical data of 32 patients with lumbosacral tuberculosis underwent the procedure of one-stage posterior intervertebral debridement, bone grafting and internal fixation from January 2007 to July 2013 were retrospectively analyzed. There were 17 males and 15 females, aged from 27 to 63 years with an average of (49.8±9.2) years. The course of disease was from 5 to 18 months with the mean of (10.7±3.2) months. There was involved the vertebral body of L₅ in 1 case, the intervertebral space of L₅S₁ in 8 cases, and the vertebral body of L₅ or S₁ combined with intervertebral space of L₅S₁ in 23 cases. VAS, ESR, CRP, the lumbosacral angle, the height of intervertebral space of L₅S₁, and ASIA grade were used to evaluate clinical effects. All the patients were followed up from 18 to 39 months with an average of 21.6 months. Operative time was 120 to 260 min with the mean of 175 min, and intraoperative bleeding was 700 to 1 450 ml with the mean of 1 050 ml. VAS before operation was 8.4±1.6, then descended to 3.5±0.8( P <0.05) on the 3rd month after operation and redescended to the level of 1.7±0.6( P <0.05) at the final follow-up. The ESR and CRP before operation were (48.8±10.2) mm and (58.6±5.6) mg/L, respectively, then decreased to (35.6±6.9) mm and (22.5±4.3) mg/L ( P <0.05) at the 3rd month after operation and returned to the normal level at the final follow-up. The height of intervertebral space of L₅S₁ and lumbosacral angle before operation were (7.7±0.4) mm and (19.3±1.2)°, respectively, then improved to (10.3±0.3) mm and (22.4±1.5)° on the 3rd month after operation( P <0.05), and maintained such level, no obvious lost at later. According to ASIA grade, 8 cases were grade C, 19 were grade D, 5 were grade E before operation, and at final follow-up, 1 case still was grade D, others were grade E. The procedure of posterior debridement, bone grafting via intervertebral space combined with internal fixation is an effective and safe method in treating lumbosacral tuberculosis, it can effectively debride tuberculose focus, maintain the spinal stability, and improve the dysfunction with less complication.

To estimate the cost of hospitalization of patients with severe sepsis or septic shock admitted or diagnosed in the Urgent and Emergency sector at a university hospital and followed until the clinical outcome. An epidemiological, prospective, observational study conducted in a public hospital in southern Brazil for the period of one year (August 2013 to August 2014). Sepsis notification forms, medical records and data of the cost sector were used for the collection of clinical and epidemiological data. The sample comprised 95 patients, resulting in a total high cost of hospitalization (R$ 3,692,421.00), and an average of R$ 38,867.60 per patient. Over half of the total value of the treatment of sepsis (R$ 2,215,773.50) was assigned to patients who progressed to death (59.0%). The higher costs were related to discharge, diagnosis of severe sepsis, the pulmonary focus of infection and the age group of up to 59 years. The high cost of the treatment of sepsis justifies investments in training actions and institution of protocols that can direct preventive actions, and optimize diagnosis and treatment in infected and septic patients. Estimar o custo da internação de pacientes com sepse grave ou choque séptico admitidos ou diagnosticados no setor de Urgências e Emergências de um hospital universitário e seguidos até o desfecho clínico. Estudo epidemiológico, prospectivo e observacional, realizado em um hospital público do sul do Brasil, no período de 1 ano (agosto de 2013 a agosto de 2014). A coleta dos dados clínico-epidemiológicos utilizou fichas de notificação de sepse, prontuários e dados do setor de custos. Foi realizada análise de tendência central, dispersão e quartis dos custos das internações. Amostra composta por 95 pacientes que totalizaram elevado custo da internação (R$ 3.692.421,00), com média de R$ 38.867,60 por paciente. Mais da metade do valor total do tratamento da sepse (R$ 2.215.773,50) destinou-se a pacientes que evoluíram a óbito (59,0%). Os maiores custos foram relacionados à alta, ao diagnóstico de sepse grave, ao foco infeccioso pulmonar e à faixa etária até os 59 anos. O elevado custo com o tratamento da sepse justificam investimentos em ações de capacitação e instituição de protocolos que possam direcionar ações preventivas, otimizar o diagnóstico e a terapêutica em pacientes infectados e séptico.

Describe the coding process of death causes for people living with HIV/AIDS, and classify deaths as related or unrelated to immunodeficiency by applying the Coding Causes of Death in HIV (CoDe) system. A cross-sectional study that codifies and classifies the causes of deaths occurring in a cohort of 2,372 people living with HIV/AIDS, monitored between 2007 and 2012, in two specialized HIV care services in Pernambuco. The causes of death already codified according to the International Classification of Diseases were recoded and classified as deaths related and unrelated to immunodeficiency by the CoDe system. We calculated the frequencies of the CoDe codes for the causes of death in each classification category. There were 315 (13%) deaths during the study period; 93 (30%) were caused by an AIDS-defining illness on the Centers for Disease Control and Prevention list. A total of 232 deaths (74%) were related to immunodeficiency after application of the CoDe. Infections were the most common cause, both related (76%) and unrelated (47%) to immunodeficiency, followed by malignancies (5%) in the first group and external causes (16%), malignancies (12 %) and cardiovascular diseases (11%) in the second group. Tuberculosis comprised 70% of the immunodeficiency-defining infections. Opportunistic infections and aging diseases were the most frequent causes of death, adding multiple disease burdens on health services. The CoDe system increases the probability of classifying deaths more accurately in people living with HIV/AIDS. Descrever o processo de codificação das causas de morte em pessoas vivendo com HIV/Aids, e classificar os óbitos como relacionados ou não relacionados à imunodeficiência aplicando o sistema Coding Causes of Death in HIV (CoDe). Estudo transversal, que codifica e classifica as causas dos óbitos ocorridos em uma coorte de 2.372 pessoas vivendo com HIV/Aids acompanhadas entre 2007 e 2012 em dois serviços de atendimento especializado em HIV em Pernambuco. As causas de óbito já codificadas a partir da Classificação Internacional de Doenças foram recodificadas e classificadas como óbitos relacionados e não relacionados à imunodeficiência pelo sistema CoDe. Foram calculadas as frequências dos códigos CoDe das causas do óbito em cada categoria de classificação. Ocorreram 315 (13%) óbitos no período do estudo; 93 (30%) tinham como causa uma doença definidora de Aids da lista do Centers for Disease Control and Prevention. No total 232 óbitos (74%) foram relacionados à imunodeficiência após aplicar o CoDe. As infecções foram as causas mais comuns, tanto nos óbitos relacionados (76%) como não relacionados (47%) à imunodeficiência, seguindo-se de malignidades (5%) no primeiro grupo e de causas externas (16%), malignidades (12%) e doenças cardiovasculares (11%) no segundo. A tuberculose compreendeu 70% das infecções definidoras de imunodeficiência. Infecções oportunistas e doenças do envelhecimento foram as causas mais frequentes de óbito, imprimindo carga múltipla de doenças aos serviços de saúde. O sistema CoDe aumenta a probabilidade de classificar os óbitos com maior precisão em pessoas vivendo com HIV/Aids.

Background The burden of chronic respiratory disease (CRD) is alarming. International studies suggest that women with CRD are undersurveyed and underdiagnosed by physicians worldwide. It is unclear what the prevalence of CRD is in the general population of Syria, particularly among women, since there has never been a survey on CRD in this nation. The purpose of this study was to investigate the impact of different patterns of smoking on CRD in women. Materials and methods We extracted data on smoking patterns and outcome in women from the Global Alliance Against Chronic Respiratory Diseases survey. Using spirometric measurements before and after the use of inhaled bronchodilators, we tracked the frequency of CRD in females active and passive narghile or cigarette smokers presenting to primary care. We administered the questionnaire to 788 randomly selected females seen during 1 week in the fiscal year 2009–2010 in 22 primary care centers in six different regions of Syria. Inclusion criteria were age >6 years, presenting for any medical complaint. In this cross-sectional study, three groups of female subjects were evaluated: active smokers of cigarettes, active smokers of narghiles, and passive smokers of either cigarettes or narghiles. These three groups were compared to a control group of female subjects not exposed to active or passive smoking. Results Exposure to active cigarette smoke but not narghile smoke was associated with doctor-diagnosed chronic obstructive pulmonary disease (COPD). However, neither cigarette nor narghile active smoking was associated with increased incidence of spirometrically diagnosed COPD. Paradoxically, exposure to passive smoking of either cigarettes or narghiles resulted in association with airway obstruction, defined as forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) < 70% according to the Global initiative for chronic Obstructive Lung Disease criteria; association with FEV1 < 80% predicted, evidencing moderate to severe GOLD spirometric grade, and doctor-diagnosed COPD. Physicians tend to underdiagnose COPD in women who present to primary care clinics. Whereas around 15% of enrolled women had evidence of COPD with FEV1/FVC < 70% after bronchodilators, only 4.8% were physician-diagnosed. Asthma did not appear to be a significant spirometric finding in these female subjects, although around 11% had physician-diagnosed asthma. One limitation is FEV1/FVC < 70% could have also resulted from uncontrolled asthma. The same limitation has been reported by the Proyecto Latinoamericano de Investigacion en Obstruccion Pulmonar (PLATINO) study. Conclusion Contrary to popular belief in developing countries, women exposed to tobacco smoke, whether active or passive, and whether by cigarettes or narghiles, like men are at increased risk for the development of COPD, although cultural habits and taboos may decrease the risk of active smoking in some women. Recommendations These findings will be considered for country and region strategy for noncommunicable diseases, to overcome underdiagnosis of CRD in women, fight widespread female cigarette and narghile smoking, and promote behavioral research in this field.

Current researches associate long fasting periods to several adverse consequences. The fasting abbreviation to 2 h to clear liquids associated with the use of drinks containing carbohydrates attenuates endocrinometabolic response to surgical trauma, but often is observed children advised to not intake food from 00:00 h till the scheduled surgical time, regardless of what it is. To evaluate the safety of a protocol of preoperative fasting abbreviation with a beverage containing carbohydrates, and early postoperative feeding in children underwent elective small/mid-size surgical procedures during a national task-force on pediatric surgery. Thirty-six patients were prospectively included, and for several reasons five were excluded. All 31 who remained in the study received a nutritional supplement containing 150 ml of water plus 12.5% maltodextrin 2 h before the procedure. Data of the pre-operative fasting time, anesthetic complications and time of postoperative refeeding, were collected. Twenty-three (74.2%) were males, the median age was 5 y, and the median weight was 20 kg. The median time of pre-operative fasting was 145 min and the time of post-operative refeeding was 135 min. There were no adverse effects on the anesthetic procedures or during surgery. Post-operatively, two children (6.5%) vomited. The abbreviation of pre-operative fasting to 2 h with beverage containing carbohydrate in pediatric surgery is safe. Early refeeding in elective small/mid-size procedures can be prescribed. Trabalhos atuais associam longos períodos de jejum com diversas consequências adversas. A abreviação do jejum de 2 h para líquidos claros associado ao uso de bebidas contendo carboidratos atenua resposta endocrinometabólica ao trauma, porém frequentemente as crianças são orientadas a não ingerir alimentos a partir das 00:00 h do dia anterior à operação, independente do horário do procedimento cirúrgico. Avaliar a segurança de um protocolo de abreviação do jejum pré-operatório, com o uso de bebida contendo carboidratos, e realimentação precoce. Foram avaliados prospectivamente 36 crianças submetidas a procedimentos cirúrgicos eletivos de pequeno e médio porte. Cinco foram posteriormente excluídos do estudo. Todos os 31 remanescentes receberam suplemento nutricional com maltodextrina 12,5% em 150 ml de água aproximadamente 2 h antes do procedimento. Foram coletados dados do tempo de jejum pré-operatório, complicações anestésicas e tempo de realimentação. Vinte e três (74,2%) eram do gênero masculino, com idade mediana de cinco anos e peso mediano de 20 kg. O tempo mediano de jejum pré-operatório foi de 145 min e o tempo mediano para realimentação foi de 135 min. Não houve eventos adversos durante a anestesia ou operação. No período pós-operatório, duas (6,5%) crianças vomitaram. A abreviação de jejum pré-operatório para 2 h com uso de bebida contendo carboidratos, em operações eletivas de crianças, é seguro e não está associado ao maior risco de broncoaspiração pulmonar. Realimentação precoce pode ser prescrita nos procedimentos cirúrgicos analisados.

To determine whether COPD severity correlates with sputum cell counts, atopy, and asthma. This was a cross-sectional study involving 37 patients with COPD and 22 healthy subjects with normal lung function (controls). Sputum cell counts were determined by microscopy after centrifugation of samples. Skin prick tests were performed, and serum cytokines were determined by ELISA. Patients were stratified by bronchodilator response: a non-reversible airflow limitation (nonRAL) group comprised 24 patients showing no significant post-bronchodilator change in FEV1; and a partially reversible airflow limitation (partialRAL) group comprised 13 patients showing FEV1 reversibility (post-bronchodilator FEV1 increase ≥ 12%). The proportion of eosinophils in sputum was higher in the partialRAL group than in the nonRAL group (p < 0.01), and there was an inverse correlation between the proportion of eosinophils and FEV1 (p < 0.05). However, none of the patients had a history of asthma and skin prick test results did not differ between the two groups. In the patient sputum samples, neutrophils predominated. Serum levels of TNF, IL-6, IL-8, and RANTES (CCL5) were higher in patients than in controls (p < 0.001) but did not differ between the two patient groups. COPD patients with partial FEV1 reversibility appear to have higher sputum eosinophil counts and greater airway hyperresponsiveness than do those with no FEV1 reversibility. However, we found that COPD severity did not correlate with atopy or with the cytokine profile. Determinar se a gravidade da DPOC se correlaciona com a contagem de células no escarro, atopia e asma. Estudo transversal com 37 pacientes com DPOC e 22 indivíduos saudáveis com função pulmonar normal (controles). As contagens de células no escarro foram determinadas por microscopia após a centrifugação das amostras. Foram realizados testes cutâneos de puntura, e as citocinas séricas foram determinadas por ELISA. Os pacientes foram estratificados pela resposta ao broncodilatador: o grupo de limitação ao fluxo aéreo não reversível (LFAnr) envolveu 24 pacientes sem alteração significativa do VEF1 pós-broncodilatador, e o grupo de limitação ao fluxo aéreo parcialmente reversível (LFApr) envolveu 13 pacientes com reversibilidade do VEF1 (aumento do VEF1 pós-broncodilatador ≥ 12%). A proporção de eosinófilos no escarro foi maior no grupo LFApr do que no LFAnr (p < 0,01), e houve uma correlação inversa entre a proporção de eosinófilos e VEF1 (p < 0,05). Entretanto, nenhum dos pacientes apresentou histórico de asma e os resultados dos testes cutâneos não diferiram entre os dois grupos. Nas amostras de escarro dos pacientes, os neutrófilos predominaram. Os níveis séricos de TNF, IL-6, IL-8 e RANTES (CCL5) foram maiores nos pacientes que nos controles (p < 0,001), mas não diferiram entre os dois grupos de pacientes. Pacientes com DPOC e reversibilidade parcial do VEF1 parecem apresentar maiores contagens de eosinófilos no escarro e maior hiper-responsividade das vias aéreas que aqueles sem reversibilidade do VEF1. Entretanto, a gravidade da DPOC não se correlacionou com atopia ou perfil das citocinas.

Cardiopulmonary exercise test (CPET) has been gaining importance as a method of functional assessment in Brazil and worldwide. In its most frequent applications, CPET consists in applying a gradually increasing intensity exercise until exhaustion or until the appearance of limiting symptoms and/or signs. The following parameters are measured: ventilation; oxygen consumption (VO2); carbon dioxide production (VCO2); and the other variables of conventional exercise testing. In addition, in specific situations, pulse oximetry and flow-volume loops during and after exertion are measured. The CPET provides joint data analysis that allows complete assessment of the cardiovascular, respiratory, muscular and metabolic systems during exertion, being considered gold standard for cardiorespiratory functional assessment.1-6 The CPET allows defining mechanisms related to low functional capacity that can cause symptoms, such as dyspnea, and correlate them with changes in the cardiovascular, pulmonary and skeletal muscle systems. Furthermore, it can be used to provide the prognostic assessment of patients with heart or lung diseases, and in the preoperative period, in addition to aiding in a more careful exercise prescription to healthy subjects, athletes and patients with heart or lung diseases. Similarly to CPET clinical use, its research also increases, with the publication of several scientific contributions from Brazilian researchers in high-impact journals. Therefore, this study aimed at providing a comprehensive review on the applicability of CPET to different clinical situations, in addition to serving as a practical guide for the interpretation of that test. Resumo O teste cardiopulmonar de exercício (TCPE) vem ganhando importância crescente como método de avaliação funcional tanto no Brasil quanto no Mundo. Nas suas aplicações mais frequentes, o teste consiste em submeter o indivíduo a um exercício de intensidade gradativamente crescente até a exaustão ou o surgimento de sintomas e/ou sinais limitantes. Neste exame se mensura a ventilação (VE), o consumo de oxigênio (VO2), a produção de gás carbônico (VCO2) e as demais variáveis de um teste de exercício convencional. Adicionalmente, podem ser verificadas, em situações específicas, a oximetria de pulso e as alças fluxo-volume antes, durante e após o esforço. A análise integrada dos dados permite a completa avaliação dos sistemas cardiovascular, respiratório, muscular e metabólico no esforço, sendo considerado padrão-ouro na avaliação funcional cardiorrespiratória.1-6 O TCPE permite definir mecanismos relacionados à baixa capacidade funcional, os quais podem ser causadores de sintomas como a dispneia, correlacionando-os com alterações dos sistemas cardiovascular, pulmonar e musculoesquelético. Também pode ser de grande aplicabilidade na avaliação prognóstica em cardiopatas, pneumopatas e em pré-operatório, além de auxiliar na prescrição mais criteriosa do exercício em sujeitos normais, em atletas, em cardiopatas e em pneumopatas. Assim como ocorre com o uso clínico, a pesquisa nesse campo também cresce e várias contribuições científicas de pesquisadores nacionais são publicadas em periódicos de alto fator de impacto. Sendo assim, o objetivo deste documento é fornecer uma revisão ampla da aplicabilidade do TCPE nas diferentes situações clínicas, bem como servir como guia prático na interpretação desse teste propedêutico.

To describe the implementation of a robotic thoracic surgery program at a public tertiary teaching hospital and to analyze its initial results. This was a planned interim analysis of a randomized clinical trial aimed at comparing video-assisted thoracoscopic surgery and robotic surgery in terms of the results obtained after pulmonary lobectomy. The robotic surgery program developed at the Instituto do Câncer do Estado de São Paulo, in the city of São Paulo, Brazil, is a multidisciplinary initiative involving various surgical specialties, as well as anesthesiology, nursing, and clinical engineering teams. In this analysis, we evaluated the patients included in the robotic lobectomy arm of the trial during its first three months (from April to June of 2015). Ten patients were included in this analysis. There were eight women and two men. The mean age was 65.1 years. All of the patients presented with peripheral tumors. We performed right upper lobectomy in four patients, right lower lobectomy in four, and left upper lobectomy in two. Surgical time varied considerably (range, 135-435 min). Conversion to open surgery or video-assisted thoracoscopic surgery was not necessary in any of the cases. Intraoperative complications were not found. Only the first patient required postoperative transfer to the ICU. There were no deaths or readmissions within the first 30 days after discharge. The only postoperative complication was chest pain (grade 3), in two patients. Pathological examination revealed complete tumor resection in all cases. When there is integration and proper training of all of the teams involved, the implementation of a robotic thoracic surgery program is feasible and can reduce morbidity and mortality. Descrever a implantação de um programa de cirurgia torácica robótica em um hospital terciário público universitário e analisar seus resultados iniciais. Este estudo é uma análise interina planejada de um ensaio clínico aleatorizado cujo objetivo é comparar resultados da lobectomia pulmonar por videotoracoscopia com a robótica. O programa de cirurgia robótica do Instituto do Câncer do Estado de São Paulo, localizado na cidade de São Paulo (SP), foi uma iniciativa multidisciplinar que envolveu diversas especialidades cirúrgicas e equipes de anestesia, enfermagem e engenharia clínica. Nesta análise, avaliamos os pacientes incluídos no braço lobectomia robótica durante os primeiros três meses do estudo (de abril a junho de 2015). Dez pacientes foram incluídos nesta análise. Eram oito mulheres e dois homens. A média de idade foi de 65,1 anos. Todos apresentavam tumores periféricos. Foram realizadas lobectomia superior direita, em quatro pacientes; lobectomia inferior direita, em quatro; e lobectomia superior esquerda, em dois. Os tempos cirúrgicos variaram bastante (variação, 135-435 min). Não foi necessária a conversão para técnica aberta ou videotoracoscópica em nenhum paciente. Não foram observadas complicações intraoperatórias. Apenas o primeiro paciente foi encaminhado à UTI no pós-operatório. Não houve mortalidade nem reinternações em 30 dias após a alta. A única complicação pós-operatória observada foi dor torácica (grau 3), em dois pacientes. O exame anatomopatológico revelou a ressecção completa do tumor em todos os casos. A implantação de um programa de cirurgia torácica robótica, quando há integração e treinamento adequado de todas as equipes envolvidas, é factível e pode reduzir a morbidade e a mortalidade.

Atrial fibrillation (AF) is a common arrhythmia, with risk of systemic embolism and death. It presents rheumatic etiology in up to 32% of developing countries, whose anticoagulation and evolution data are scarce. to determine the predictors of cardiac death considering the clinical profile, thromboembolism and bleeding scores of patients with AF of a single center, with high prevalence of rheumatic heart disease. 302 patients with AF were studied, mean age 58.1 years; 161 women; 96 pts with rheumatic etiology. Patients underwent clinical and laboratory evaluation, measurement of risk scores and the mean follow-up of 12.8 months. 174 were using warfarin. The averages of the HAS-BLED and ATRIA scores were 1.4 and 1.2, respectively. Percent time in therapeutic range of international normalized ratio was 45.8%. Thirty patients (9.9%) had cardiac death and 41 had some type of bleeding due to warfarin. By univariate analysis, there was statistical significance between cardiac death and permanent AF, blood pressure, systolic dysfunction, R2CHADS2, CCS, EHRA and HAS-BLED. There was no association with valvular AF. By multivariate analysis, systemic arterial and pulmonary artery pressures, classification CCS and systolic dysfunction showed statistical significance. There was no association between cardiac death and valvular AF. Independent predictors of cardiac death were low measures of blood pressure, higher score CCS classification and the presence of systolic ventricular dysfunction. A fibrilação atrial (FA) é uma arritmia comum, com risco de embolia sistêmica e morte. Apresenta etiologia reumática em até 32% dos países em desenvolvimento, cujos dados de anticoagulação e evolução são escassos. Verificar as variáveis preditoras de morte cardíaca (MC) conforme o perfil clínico, os escores de tromboembolismo e de sangramento dos pacientes com FA de uma única instituição universitária, com alta prevalência de cardiopatia reumática. Foram estudados 302 pts com FA, média de idade 58,1 anos; 161 mulheres; 96 pts com etiologia reumática. Os pts foram submetidos à avaliação clínica e laboratorial, ao cálculo dos escores de risco e ao seguimento clínico médio de 12,8 meses. 174 pts estavam em uso de varfarina. As médias dos escores HAS-BLED e ATRIA foram de 1,4 e de 1,2, respectivamente. O cálculo da fração dos valores da razão normalizada internacional dentro do intervalo terapêutico foi de 45,8%. Houve MC em 30 pts (9,9%) e 41 apresentaram algum tipo de hemorragia em decorrência do uso de varfarina. Pela análise univariada, houve significância estatística entre MC e FA permanente, pressões arteriais, disfunção sistólica, R2CHADS2, CCS, EHRA e HAS-BLED. Não houve associação com FA valvar. Por meio da análise multivariada, a pressão arterial sistêmica e da artéria pulmonar, a classificação CCS e a disfunção sistólica apresentavam significância estatística. Não houve associação entre MC e FA valvar. Os preditores independentes de MC foram medidas baixas de pressão arterial, escores mais elevados da classificação CCS e a presença de disfunção ventricular sistólica.

Most severe pregnancy complications are characterized by profound hemodynamic disturbances, thus there is a need for validated hemodynamic monitoring systems for pregnant women. Pulmonary artery catheterization (PAC) using thermodilution is the clinical gold standard for the measurement of cardiac output (CO), however this reference method is rarely performed owing to its invasive nature. Transthoracic echocardiography (TTE) allows non-invasive determination of CO. We aimed to validate TTE against PAC for the determination of CO in severely ill pregnant women. This study consisted of a meta-analysis combining data from a prospective study and a systematic review. The prospective arm was conducted in Pretoria, South Africa, in 2003. Women with severe pregnancy complications requiring invasive monitoring with PAC according to contemporary guidelines were included. TTE was performed within 15 min of PAC and the investigator was blinded to the PAC measurements. Comparative measurements were extracted from similar studies retrieved from a systematic review of the literature and added to a database. Simultaneous CO measurements by TTE and PAC were compared. Agreement between methods was assessed using Bland-Altman statistics and intraclass correlation coefficients (ICC). Thirty-four comparative measurements were included in the meta-analysis. Mean CO values obtained by PAC and TTE were 7.39 L/min and 7.18 L/min, respectively. The bias was 0.21 L/min with lower and upper limits of agreement of -1.18 L/min and 1.60 L/min, percentage error was 19.1%, and ICC between the two methods was 0.94. CO measurements by TTE show excellent agreement with those obtained by PAC in pregnant women. Given its non-invasive nature and availability, TTE could be considered as a reference for the validation of other CO techniques in pregnant women. Copyright © 2016 ISUOG.

Las complicaciones del embarazo más graves se caracterizan por trastornos hemodinámicos serios, debido a los cuales existe la necesidad de sistemas validados de monitorización hemodinámica para mujeres embarazadas. Aunque la cateterización de la arteria pulmonar (CAP) mediante termodilución es el patrón de referencia clínico para la medición del gasto cardíaco (GC), este método se usa con poca frecuencia debido a su naturaleza invasiva. La ecocardiografía transtorácica (ETT) permite la determinación no invasiva del GC. El objetivo de este estudio fue validar la ETT frente al CAP para determinar el GC en mujeres embarazadas gravemente enfermas. MÉTODOS: Este estudio consistió en un metaanálisis que combinó datos de un estudio prospectivo y una revisión sistemática. El estudio prospectivo se llevó a cabo en Pretoria (Sudáfrica) en 2003. Se incluyeron mujeres con complicaciones graves en el embarazo que requerían una monitorización invasiva mediante CAP según las directrices de ese momento. Se realizó una ETT en un plazo de 15 minutos de haber realizado el CAP y el investigador no tuvo acceso a las mediciones del CAP. Las mediciones comparativas se extrajeron de estudios similares obtenidos a partir de una revisión sistemática de la literatura y se añadieron a una base de datos. Se compararon las mediciones simultáneas del GC mediante ETT y CAP. La concordancia entre métodos se evaluó a través del método estadístico de Bland-Altman y de coeficientes de correlación intraclase (CCI). Se incluyeron treinta y cuatro mediciones comparativas en el metaanálisis. Los valores medios del GC obtenidos mediante CAP y ETT fueron de 7,39 l/min y 7.18 l/min, respectivamente. El sesgo fue de 0,21 l/min, siendo los límites inferior y superior de la concordancia de -1,18 l/min y 1.60 l/min; el error porcentual fue del 19,1%, y el CCI entre ambos métodos fue de 0,94. Las mediciones del GC en mujeres embarazadas mediante ETT muestran una excelente concordancia con las obtenidas mediante CAP. Dada su naturaleza no invasiva y su disponibilidad, la ETT podría considerarse como referencia para la validación de otras técnicas relacionadas con el GC en mujeres embarazadas. : ,。(pulmonary artery catheterization,PAC)(cardiac output,CO),,。(transthoracic echocardiography,TTE)CO。PACTTECO。 : meta。2003。PAC。PAC 15 minTTE,PAC。,。TTEPACCO。Bland-Altman(intraclass correlation coefficients,ICC)。 : meta34。PACTTECO7.39 L/min7.18 L/min。-1.18 L/min、1.60 L/min0.21 L/min,19.1%,ICC0.94。 : TTECOPACCO。,TTECO。.

SUMMARY SETTING: Alcohol use, tuberculosis (TB) drug resistance and human immunodeficiency virus (HIV) risk behavior are of increasing concern in Russian TB patients. DESIGN: A prevalence study of alcohol use and HIV risk behavior was conducted in a sample of 200 adult men and women admitted to TB hospitals in St Petersburg and Ivanovo, Russia. RESULTS: Of the subjects, 72% were men. The mean age was 41. Active TB was diagnosed using a combination of chest X-ray, sputum smears and sputum cultures. Sixty-two per cent met DSM-IV criteria for current alcohol abuse or dependence. Drug use was uncommon, with only two patients reporting recent intravenous heroin use. There was one case of HIV infection. The mean total risk assessment battery score was 3.4. Depression was present in 60% of the sample, with 17% severely depressed. Alcohol abuse/dependence was associated with an eight-fold increase in drug resistance (OR 8.58; 95% CI 2.09-35.32). Patients with relapsing or chronic TB were more likely to meet the criteria for alcohol abuse/dependence (OR 2.56; 95% CI 1.0-6.54). CONCLUSION: Alcohol use disorders are common in patients being treated for active TB, and are associated with significant morbidity. Additional surveys are needed to examine the relationship between alcohol use disorders and anti-tuberculosis drug resistance. CONTEXTE: Chezles patients tuberculeux russes, l’utilisation d’alcool, la résistance aux médicaments antituberculeux et un comportement à risque pour le virus de l’immunodéficience humaine (VIH) sont des sujets croissants d’inquiétude. SCHÉMA: Une étude: de prévalence de l’utilisation d’alcool et du comportement à risque pour le VIH a été menée sur un échantillon de 200 hommes et femmes adultes, admis dans des hôpitaux pour la tuberculose (TB) de Saint-Pétersbourg et d’Ivanovo en Russie. RÉSULTATS: Il y avait 72% d’hommes dans l’échantillon. L’âge moyen est de 41 ans. On a diagnostiqué la TB active par l’emploi d’une combinaison du cliché thoracique, de la bacilloscopie et des cultures d’expectoration. Chez 62% des patients, les critères DSM-IV pour utilisation courante d’alcool ou pour dépendance étaient présents. L’utilisation de drogues est inhabituelle: deux patients seulement ont signalé une utilisation récente de l’héroïne par voie intraveineuse. Il n’y avait qu’un seul cas d’infection VIH. Le score total moyen de la batterie d’évaluation des risques a été de 3,4. Il y avait de la dépression chez 60% de 1’échantillon, dont 17% étaient en dépression sévère. L’utilisation ou la dépendance à l’égard de l’alcool étaient associées avec une multiplication par huit de la résistance aux médicaments (OR 8,58 ; IC95% 2,09-35,32). Les patients atteints de rechute de TB ou de TB chronique sont plus susceptibles de répondre aux critérés d’abus ou de dépendance de l’alcool (OR 2,56; IC95% 1,0-6,54). CONCLUSION: Les maladies liées à l’utilisation d’alcool sont fréquentes chez les patients traités pour TB active et sont associées à une morbidité significative. Des enquêtes complémentaires sont nécessaires pour examiner les relations entre les maladies liées à l’utilisation d’alcool et la résistance à l’égard des médicaments antituberculeux. MARCO DE REFERENCIA: El consumo de alcohol, la tuberculosis (TB) farmacorresistente y los comportamientos de riesgo para la infección por el virus de la inmunodeficiencia humana (VIH) constituyen una preocupación creciente en los pacientes con TB en la Fedéración de Rusia. MÉTODOS: Se llevó a cabo un estudio de prevalencia del consumo de alcohol y del comportamiento de riesgo para la infección por el VIH en una muestra de 200 adultos, hombres y mujeres, ingresados por TB en dos hospitales de San Petersburgo e Ivanovo en la Federación de Rusia. RESULTADOS: El 72% de los individuos fueron de sexo masculino. La media de la edad fue 41 años. El diagnóstico de TB activa se estableció mediante una combinación de criterios que incluyeron la radiografía de tórax y la baciloscopia y cultivo del esputo. El 62% de los individuos cumplió con los criterios diagnósticos de alcoholismo actual o dependencia al alcohol de la nomenclatura del DSM-IV. El consumo de drogas fue poco frecuente, pues sólo dos pacientes comunicaron uso intravenoso reciente de heroína. Se observó un caso de infección por el VIH. La media total obtenida con el cuestionario auto-administrado para evaluación de los comportamientos de riesgo para sida (risk assessment battery) fue 3,4. El 60% de los pacientes presentaron depresión y en 17% la depresión fue grave. El alcoholismo y la dependencia al alcohol se asociaron con una frecuencia ocho veces mayor de farmacorresistencia (OR 8,58; IC95% 2,09-35,32). Los pacientes con TB crónica o recaída tuvieron mayor probabilidad de cumplir con los criterios para alcoholismo y dependencia al alcohol (OR 2,56; IC95% 1,0–6,54). CONCLUSIÓN: Los trastornos por consumo de alcohol son frecuentes en pacientes tratados por TB activa y se asocian con una morbilidad considerable. Se precisan estudios adicionales para evaluar la relación entre estos trastornos y la resistencia a los medicamentos antituberculosos. PMID:16704041
