Concep??o e organiza??o de um centro de controle de intoxica??es
Baroud,Ricardo;
Revista de Saúde Pública , 1985, DOI: 10.1590/S0034-89101985000600007
Abstract: as a contribution to a better understanding of the importance of poison control centers, the present work focuses on their conception, organization and action as part of government institutions, private entities and the community. the importance of the sectors that deal with prevention and epidemiology, toxicological analysis and scientific research in these centers is particularly emphasized. also the necessity for intervention in the areas of preventive public health by means of the creation of plans of action, particularly those related to public awareness, education and mental health, is stressed. finally suggestions are made which, if implemented, should facilitate the understanding of cases of poisoning and hence diminish their incidence; this should result, in turn, in economy of available government resources, permiting development of more comprehensive treatment programs for patients suffering from poisoning.

Abstract: Forty four macrolide resistant and 21 macrolide susceptible S. pneumoniae clinical isolates were tested for antimicrobial susceptibility according to CLSI guidelines (2008) and underwent molecular characterization. Serotyping of these isolates was performed by Multiplex PCR-based serotype deduction using CDC protocols. PCR amplification of macrolide resistant erm (encoding methylase) and mef (encoding macrolide efflux pump protein) genes was carried out.Among 44 isolates resistant to erythromycin, 35 were resistant to penicillin and 18 to ceftriaxone. Examination of 44 macrolide resistant isolates by PCR showed that 16 isolates harbored the erm(B) gene, 8 isolates harbored the mef gene, and 14 isolates harbored both the erm(B) and mef genes. There was no amplification by PCR of the erm(B) or mef genes in 6 isolates. Seven different capsular serotypes 2, 9V/9A,12F, 14,19A, 19F, and 23, were detected by multiplex PCR serotype deduction in 35 of 44 macrolide resistant isolates, with 19F being the most prevalent serotype. With the exception of serotype 2, all serotypes were invasive. Isolates belonging to the invasive serotypes 14 and 19F harbored both erm(B) and mef genes. Nine of the 44 macrolide resistant isolates were non-serotypable by our protocols.Macrolide resistance in S. pneumoniae in Lebanon is mainly through target site modification but is also mediated through efflux pumps, with serotype 19F having dual resistance and being the most prevalent and invasive.Streptococcus pneumoniae continues to be a major cause of morbidity and mortality in humans. It is one of the most significant bacterial pathogens causing community acquired infections, most notably pneumonia, otitis media, bacteremia, and meningitis [1,2]. Treatment of pneumococcal infections is becoming difficult due to the high prevalence of penicillin-resistant strains and to the rapid development of resistance to other antimicrobials including macrolides. These drugs are extensively used for the treat
Tip streaming from drops flowing in a spiral microchannel
Simon Molesin,Charles N. Baroud
Physics , 2008,
Abstract: This fluid dynamics video shows drops of water being transported by a mean flow of oil, in a microchannel shaped as a logarithmic spiral. The channel shape means that the drops are submitted to an increasing shear and elongation as they flow nearer to the center of the spiral. A critical point is reached at which a long singular tail is observed behind the drops, indicating that the drops are accelerating. This is called "Tip streaming".

Theoretical and experimental approach to test the cohesion of calcium phosphate pastes
M Bohner,N Doebelin,G Baroud
European Cells and Materials (ECM) , 2006,
Abstract: Recent studies have revealed that the ability of a calcium phosphate cement paste to harden in a physiological environment without desintegrating into small particles might be a key property to ensure a safe and reliable clinical use of calcium phosphate cements. However, this property called cohesion is not well understood and has not been studied extensively. The goal of the present study was to better understand which factors affect the cohesion of a calcium phosphate paste using the combination of a theoretical and experimental approach. In the theoretical approach, factors expected to influence the paste cohesion such as Van der Waals forces, electrostatic and steric interactions, as well as osmotic effects were listed and discussed. In the experimental approach, a new method to measure the cohesion of a non-setting calcium phosphate paste was presented and used to assess the effects of various factors on this property. The new method allowed a continuous measurement of cohesion and gave reproducible results. The experimental results confirmed the theoretical predictions: an increase of the liquid-to-powder ratio of the paste and of the powder particle size, as well as the addition of citrate ions and in limited cases dissolved xanthan polymer chains reduced the paste cohesion.
Radiologia do cancer de pulm?o

Abstract: the evaluation of patients with lung cancer involves not only the detection of enlarged mediastinal lymph nodes and the delineation of the relationship between the primary lesion with the mediastinal structures but also the determination of extra thoracic metastases. this article reviews the major imaging techniques that are currently used to stage bronchogenic carcinoma. radiologic studies have made an important impact on the evaluation of the solitary pulmonary nodule. mediastinal staging coupled with imaging methods is not accurate. ct and mr imaging of the chest and abdomen are often used to stage a known or suspected lung carcinoma. despite their limitations, ct and mr prevent unnecessary thoracotomies and invasive procedures. mr can be helpful in the evaluation of parts of the chest not well shown on ct. pet-fdg imaging complements chest ct in the noninvasive evaluation of lung cancer and strategies for its use merit further investigation.

Radiologia do cancer de pulm o
BARCELLOS MAYSA GOMES
Jornal de Pneumologia , 2002,
Abstract: A avalia o do paciente com cancer de pulm o envolve a detec o de aumento linfonodal mediastinal, invas o das estruturas mediastinais e também a determina o de metástases extratorácicas. Este artigo revisa a maioria das técnicas de imagem mais utilizadas no processo de estadiamento do cancer pulmonar broncogênico. O estudo radiológico do nódulo pulmonar solitário tem tido grande impacto. Estadiamento mediastinal com os métodos de imagem correntes é impreciso. TC e RM do tórax e abdome superior s o freqüentemente usados para estadiar o cancer pulmonar presumido ou conhecido. A despeito de suas limita es, os estudos de imagem podem prevenir toracotomias ou procedimentos invasivos desnecessários na presen a de achados inequívocos de doen a avan ada. RM pode ser útil na avalia o de regi es do tórax que s o maldemonstradas nas imagens axiais de TC. PET-FDG é um método complementar ao TC na avalia o do paciente com cancer de pulm o, porém estratégias para o seu uso merecem futuras investiga es.

Abstract: introduction: seroma, hematoma and wound alterations are potential complications following abdominoplasty. aspiratory drainage and adhesion suture are widely employed strategies for prevention of these complications. the purpose of this study is to evaluate the efficacy of adhesion suture in preventing or reducing seroma, hematoma formation and local wound complications in patients undergoing plastic of body countering. methods: 115 patients (group 2: january 2006 - june 2010) who underwent plastic of body countering with the use of adhesion suture were retrospectively compared with a group of 39 patients (group 1: january 2004 - december 2005) who underwent with the use aspiratory drainage. clinical evaluation of the patients was performed seven days, two weeks, one, two, three and six months postoperatively. results: in group 1, there was 9 (23%) cases of seroma, 1 (2.5%) case of hematoma and 20 (55%) cases of wound complications, whereas in group 2 no seroma or hematoma was reported. in this group, there were 14 (12%) cases of wound complications. clinical evaluation revealed statistical difference between the use of adhesion suture and the aspiratory drainage in the incidence of seroma and wound complications. conclusion: the use of adhesion suture is an effective measure to prevent seroma, hematoma and wound complications in patients undergoing plastic of body countering.
Thermocapillary valve for droplet production and sorting
C. N. Baroud,J. -P. Delville,F. Gallaire,R. Wunenburger
Physics , 2006, DOI: 10.1103/PhysRevE.75.046302
Abstract: Droplets are natural candidates for use as microfluidic reactors, if active control of their formation and transport can be achieved. We show here that localized heating from a laser can block the motion of a water-oil interface, acting as a microfluidic valve for two-phase flows. A theoretical model is developed to explain the forces acting on a drop due to thermocapillary flow, predicting a scaling law which favors miniaturization. Finally, we show how the laser forcing can be applied to sorting drops, thus demonstrating how it may be integrated in complex droplet microfluidic systems.
