Abstract: the serological screening of blood donors does not constitute a 100% guarantee of protection against the possible transmission of infectious and contagious agents. the ministry of health determines that tests for syphilis, hepatitis b and c, aids, chagas' disease and htlv i/ii, as well as malaria in endemic areas, are mandatory in all the blood collection bags used in brazil. the samples from blood donors must be stored for six months. concerning the recipients of blood, the ministry determines that pre-transfusional immunohematological tests such as abo/rh classification, irregular antibody titers and compatibility must be preformed. in these cases, the sample from the recipient is stored for ten days. considering that some pathologies tested, when not detected in donors, can still be transmitted to the recipients and remain asymptomatic for several decades, a study of cause-effect among recipients and their respective donors is impaired. a recent study in brazil analyzed recipients of blood without any history of transfusion as well as eventual and multitransfused recipients. it showed an important prevalence of the pathologies transmitted by blood transfusion. the study also revealed that a high percentage of recipients that were reactive, were unaware of their serological status before their transfusion. transfusional safety and the serological pre-transfusional evaluation in recipients of blood are points discussed in this review.

Abstract: venipuncture is one of the easiest clinical procedures to obtain viable blood samples to evaluate gene expression using mrna analysis. however, the use of this sample type in reverse transcriptase polymerase chain reaction tests (rt-pcr) without prior treatment is controversial. we therefore propose to compare the suitability of different peripheral blood samples (whole blood without treatment, whole blood with hemolysis, peripheral blood mononuclear cells and frozen whole blood) for rt-pcr analysis. the results showed that, despite the blood sample being peripheral, it is possible to extract a fair amount of rna and perform target gene amplification. thus, peripheral blood without prior treatment could be used to investigate the gene expression using real time pcr.

Abstract: introduction: a time series study of admissions, deaths and acute cases was conducted in order to evaluate the context of chagas disease in pernambuco. methods: data reported to the information technology department of the brazilian national health service between 1980 and 2008 was collected for regions and federal units of brazil; and microregions and municipalities of pernambuco. rates (per 100,000 inhabitants) of hospitalization, mortality and acute cases were calculated using a national hospital database (sih), a national mortality database (sim) and the national information system for notifiable diseases (sinan), respectively. results: the national average for chagas disease admissions was 0.99 from 1995 to 2008. pernambuco obtained a mean of 0.39 in the same period, with the highest rates being concentrated in the interior of the state. the state obtained a mean mortality rate of 1.56 between 1980 and 2007, which was lower than the national average (3.66). the mortality rate has tended to decline nationally, while it has remained relatively unchanged in pernambuco. interpolating national rates of admissions and deaths, mortality rates were higher than hospitalization rates between 1995 and 2007. the same occurred in pernambuco, except for 2003. between 2001 and 2006, rates for acute cases were 0.56 and 0.21 for brazil and pernambuco, respectively. conclusions: although a decrease in chagas mortality has occurred in brazil, the disease remains a serious public health problem, especially in the northeast region. it is thus essential that medical care, prevention and control regarding chagas disease be maintained and improved.

Abstract: the epithelial cells of panstrongylus megistus male accessory glands (mag) present ultrastructural characteristics of a secretory cell. their secretory products are accumulated in the lumen of the four mag lobes. during the first 8 days of adult life a strong secretion activity occurs, accumulating enough material to produce the first spermatophore. cerebral neurosecretions as well as juvenile hormone are both involved in mag secretory activity regulation. juvenile hormone seems to be the responsible for the stimulation of most protein synthesis in male accessory glands. cerebral neurosecretion seems to be necessary to stimulate juvenile hormone production and release by the corpus allatum. furthermore, neurosecretion is required for some polypeptides synthesis by mag. although topic application of precocene ii to adult males does not reproduce the same effects on mag as does allatectomy, this compound causes strong reduction on male reproductive capacity.

Abstract: introduction: with the introduction of tumor necrosis factor inhibitors (anti-tnfs) into rheumatological practice, it has become obligatory to identify cases of latent tuberculosis infection (ltbi) prior to the start of treatment, using ppd, chest radiography and clinical history of tuberculosis contact. patients with rheumatoid arthritis (ra) have an abnormality of the cellular immune function, characterized by decreasing responsiveness of peripheral mononuclear cells (t reg lymphocytes), leading to a loss in delayed hypersensitivity, which is fundamental for the recognition of antigens, such as ppd. objectives: the purpose of our study was to evaluate the response to ppd in patients with ra, compared with healthy people, in an area where tuberculosis is endemic, as is the state of pernambuco. methodology: we studied 96 patients, 48 with ra and 48 healthy subjects, most of them females. all patients were given an interdermic injection of 0.1 ml ppd rt-23. the reading of the ppd result was carried out 72 hours after application, by way of palpation of maximum transverse diameter of induration, and the result was expressed in millimeters. results:in the ra group, the average time of diagnosis was 10.2 years, the average dosage of methotrexate was 15.5 mg / week, the average dosage of prednisone 12.7 mg / day and the average activity of the disease, measured using cdai, was 30.4. in the healthy subjects group there was a greater number of positive ppd results (33.3%) when compared with the results for the ra group (14.6%), with a statistically significant difference (p = 0.034). conclusion:the performance of ppb in ltbi diagnosis is poor in patients with ra. these results suggest that more careful screening needs to be undertaken before treatment with an anti-tnf drug.

Abstract: chagas disease is a systemic infection with a chronic onset transmitted by trypanosoma cruzi. the last study conducted in recife, capital of pernambuco state, was carried out during 1970. at that time a prevalence of 4.4% was found among blood donors of a local hospital. due to the lack of epidemiology data on t. cruzi infection and as pernambuco is an endemic region, the present study describes the profile of blood donors who presented reactivity for chagas disease during the period of 2002 to 2007 in the state's blood bank (hemope). the profile of unsuitable donors was evaluated according to gender, age and according to the meso-regions of pernambuco. a prevalence of 0.17% was found for chagas disease, whereas 6.89% of the rejected blood bags were due to this reactivity. as far as gender is concerned, the reactivity of men was higher than that of women (p<0.0001). additionally, the age group between 18-30 years was less infected (20.21%). on analyzing the reactivity in each one of the meso-regions of the state, it was found that, in the metropolitan region of recife, the number of inconclusive reaction cases was statistically higher than the number of reactive serology cases (p=0.0440). thus, epidemiological studies provide important data to indirectly evaluate the risk of blood-borne diseases and allow indirect evaluation of the effectiveness of vectorial control measures in endemic regions.

Abstract: 62 axillas, 32 on the right upper limb and 30 on the left one were analyzed aiming a more detailed study of the topographic relationship between the brachial plexus' (bp) cords and the second part of the axillary artery (aa). once the second part of the aa was determined (retropectoral part of the axilla) the authors observed that some of the bp's cords lost their identity during the length of the above-mentioned part of the axilla, so, the analysis of these cords and their relationship with the aa was effected on the beginning of the retropectoral region. it was verified that in 27,42% of the cases, pb's cords surrounded the 2nd part of the aa positioned according to their names - lateral cord (lc), medial cord (mc) and posterior cord (pc) - being this the most mentioned disposition in literature. in 16,13% of the cases, it was observed that mc and pc were disposed posteriorly to the aa, while lc was situated laterally to the artery. in 3,23 % of the cases, lc and mc were found anteriorly, and pc posteriorly to the aa; in the same percentage of cases, all the cords were situated laterally to the aa. only in 1,62%, mc and pc were situated according to their names, and the lc was anterior to the aa. the majority of cases in which the cords were present, they disposed themselves differently of what the analyzed literature shows

Abstract: humoral and cellular immune responses were evaluated in 44 c57bl/6 mice immunized with the trypanosoma cruzi recombinant antigens cra and fra. both antigens induced cutaneous immediate-type hypersensitivity response. the levels of igg1, igg2a, igg2b and igg3 were high in cra immunized mice. igg3 was the predominant isotype. although no difference in antibody levels was observed in fra-immunized mice when compared to control mice, both antigens were able to induce lymphoproliferation in immunized mice. significant differences were observed between incorporation of [3h]- thymidine by spleen cell stimulated in vitro with cra or fra and the control group. these results suggest that cra and fra could be involved in mechanisms of resistance to trypanosoma cruzi infection.
