Memórias do Instituto Oswaldo Cruz , 2003,
Abstract: To clarify the epidemiologic importance of Triatoma brasiliensis, the most important Chagas disease vector in the Northeastern of Brazil, capture data related to this species, its distribution, capture index, and percentages of natural infection by Trypanosoma cruzi were examined in 12 different Brazilian states. The Brazilian National Health Foundation collected these data from 1993 to 1999, a period during which a total of 1,591,280 triatomines (21 species) were captured in domiciles within the geographic range of T. brasiliensis. Of this total, 422,965 (26.6%) were T. brasiliensis, 99.8% of which were collected in six states, and 54% in only one state (Ceará). The percentage of bugs infected with T. cruzi varied significantly among states, ranging from 0% (Goiás, Maranh o, Sergipe, and Tocantins) to more than 3% (Alagoas, Minas Gerais, and Rio Grande do Norte) with an average of 1.3%. This latter value represents a dramatic reduction in the natural infection percentages since 1983 (6.7%) suggesting that, despite the impossibility of eradicating this native species, the control measures have significantly reduced the risk of transmission. However, the wide geographic distribution of T. brasiliensis, its high incidence observed in some states, and its variable percentages of natural infection by T. cruzi indicate the need for sustained entomological surveillance and continuous control measures against this vector.

Abstract: background and objectives: the association of isobaric bupivacaine to lower spinal sufentanil dose provides satisfactory analgesia and lower incidence of side effects. this study aimed at evaluating quality of analgesia and incidence of side effects of decreased spinal sufentanil doses associated to hyperbaric bupivacaine for labor analgesia. methods: participated in this study 69 healthy term pregnant patients in active labor. patients were randomly allocated in three groups receiving spinal combination of 2.5 mg hyperbaric bupivacaine and 1 ml saline solution (control group); 2.5 mg hyperbaric bupivacaine and 2.5 μg sufentanil (s2.5 group) or 2.5 mg hyperbaric bupivacaine and 5 μg sufentanil (s5 group). pain, using a visual analogue scale (vas), and side effects were evaluated at 5-minute intervals for the first 15 minutes and then at 15-minute interval until delivery. study would end with delivery or when patient requested rescue analgesia (vas > 3 cm). results: groups s2.5 and s5 presented longer analgesia duration (67.2 ± 38.6 and 78.9 ± 38.7 minutes, respectively) and a larger number of patients with effective analgesia (100% and 95.6%, respectively) as compared to control group where mean analgesia duration was 35.9 ± 21.6 minutes (p < 0.05) with 69.6% of patients with effective analgesia (p < 0.05). conclusions: the association of sufentanil to hyperbaric bupivacaine improves quality and prolongs analgesia duration. when associated to 2.5 mg hyperbaric bupivacaine, there is no benefit in administering more than 2.5 μg of sufentanil for labor pain relief.
Use of tandem stents for treatment of helicoidal dissection of the right coronary artery
Furukawa Murillo K.,Domingues Carlos Eduardo M.,Almeida Marcos César V. de,Franco Jr Virgílio Ribeiro
Arquivos Brasileiros de Cardiologia , 2000,
Abstract: Coronary dissection occurs frequently and in several degrees during coronary angioplasty, which is one of the mechanisms for increasing the lumen diameter of a vessel. However the length of the dissection may affect the procedure, becoming the most frequent cause of total occlusion after coronary angioplasty. We report here a case of extensive dissection that occurred during the coronary angioplasty of a focused lesion, which we treated with two long stents.

Abstract: this is the first report on the occurrence of cocaine (coc) and benzoylecgonine (be) residues in six samples collected from different wastewater treatment plants (wtp) located in the brazilian federal district (fd). concentrations of be in the influent sewage were used to calculate cocaine consumption (kg year-1 per 1000 inhabitants) for each region attended by the wtp from two sampling campaigns (march and june, 2010). among the wtp studied, samples from samambaia showed higher concentrations (from 3866 to 2477 ng l-1 of be and 805 to 579 ng l-1 of coc) and doses per inhabitants (more than 13 doses inhabitant-1 per year). the extrapolation to the whole fd population points out to an annual consumption reaching 1.0 ton of free base cocaine, or 1.1 tons of cocaine hydrochloride. the work also addresses the influence of the cocaine presentation form (free base or hydrochloride) and the integration with chemical profiling results in a more realistic estimate, mainly concerning the viewpoints of forensics and law enforcement.

Abstract: cyclometallated palladium(ii) complexes are reactive inorganic compounds employed in several biological studies because of their antitumour potential and interaction with immune system. in the present study, the immune and citotoxic response induced by two organopalladated complexes: [{pd(n,c-dmba)}2(μ-ncs)2 ] (1), [pd(c-dmba)(ncs)(dppp)] (2) [dmba = n,n'dimethylbenzylamine, dppp = 1,3-bis(diphenylphosphino)propane] and cisplatin (cis-ddp), as standard, were investigated in mice bearing ehrlich ascites tumour. the mice were divided into five groups and inoculated with the compounds (1) or (2) or cisplatin, or only vehicle or phosphate-buffered saline (pbs). many parameters were evaluated, such as tumour cell percentage in the peritoneal exsudate, levels of seric nitric oxide (no) and tumour necrosis factor-alpha (tnf-a) and increase in life span. analysis of all data revealed, for compound (2), an activity similar to that presented by cisplatin, resulting in increased life span, lower levels of seric tnf-a and increase in no production.

Revista do Instituto de Medicina Tropical de S?o Paulo , 2012, DOI: 10.1590/S0036-46652012000200007
Abstract: this study examined the susceptibility of peritoneal macrophage (pm) from the neotropical primates: callithrix jacchus, callithrix penicillata, saimiri sciureus, aotus azarae infulatus and callimico goeldii to ex vivo leishmania (l.) infantum chagasi-infection, the etiological agent of american visceral leishmaniasis (avl), as a screening assay for evaluating the potential of these non-human primates as experimental models for studying avl. the pm-susceptibility to infection was accessed by the pm-infection index (pmi) at 24, 72 h and by the mean of these rates (fpmi), as well as by the tnf-α, il-12 (capture elisa) and nitric oxide (no) responses (griess method). at 24h, the pmi of a. azarae infulatus (128) was higher than those of c. penicillata (83), c. goeldii (78), s. sciureus (77) and c. jacchus (55). at 72h, there was a significant pmi decrease in four monkeys: a. azarae infulatus (128/37), c. penicillata (83/38), s. sciureus (77/38) and c. jacchus (55/12), with exception of c. goeldii (78/54). the fpmi of a. azarae infulatus (82.5) and c. goeldii (66) were higher than c. jacchus (33.5), but not higher than those of c. penicillata (60.5) and s. sciureus (57.5). the tnf-a response was more regular in those four primates which decreased their pmi at 24/72 h: c. jacchus (145/122 pg/ml), c. penicillata (154/130 pg/ml), s. sciureus (164/104 pg/ml) and a. azarae infulatus (154/104 pg/ml), with exception of c. goeldii (38/83 pg/ml). the il-12 response was mainly prominent in a. infulatus and c. goeldii which presented the highest fpmi and, the no response was higher in c. goeldii, mainly at 72 h. these findings strongly suggest that these new world primates have developed a resistant innate immune response mechanism capable of controlling the macrophage intracellular growth of l. (l.) i. chagasi-infection, which do not encourage their use as animal model for studying avl.

Abstract: objective: an anonymous mail survey was carried out with brazilian psychiatrists affiliated with brazilian psychiatric association (abp). a structured questionnaire was employed to assess use and perceived utility of current diagnostic classifications (icd-10 and dsm-iv), as well as their expectations about the future revisions. methods: from the mailing list provided by abp with 3,062 names of affiliated brazilian psychiatrists, 1,050 were randomly selected to receive the questionnaire, along with a stamped, return address envelope. from the sample of 1,050, 160 completed questionnaires were returned, which corresponds to the following rate of response: 15.2%. no claims are made about the representativeness of the sample. results: it was found that the icd-10 is the most frequently used system, especially its clinical axis. the dsm-iv's axes i and ii are often used as well. for this sample the most important purpose of a classification is to ensure reliable inter-clinician communication. classifications are seen as tools for psychiatric use and, to a lesser extent, for the use of a multidisciplinary team. current diagnostic systems are perceived as reliable for cross-cultural use in our context. regarding expectations about the future revisions, brazilian psychiatrists prefer simpler classifications, with less than 100 diagnostic labels. they split, however, about having separate systems to account for cause/pathogenesis and to inform treat ment plans or a single classification, with many compromises, to convey information concerning causes, prognosis and treatment decisions. conclusions: classificatory systems play an important role in everyday psychiatric clinical practice in this sample of psychiatrists. brazilian psychiasystems. trists' opinions seem to reflect well existing controversies regarding some key nosographic issues.
