Abstract: purpose: to evaluate whether the sample adequacy influences the detection of precursor cervical cancer lesions. methods: a transversal study from january 2004 to december 2005. a number of 10,951 results of cervical cytotopathological exams from users of the national health system (sistema único de saúde, sus) in goiania, goiás , brazil, was studied. these women had spontaneously looked for the services from the family health program or from the basic units of health. samples were collected by medical doctors and nurses, through the conventional technique to detect cervical cancer. the analyzed smears were classified by the bethesda system, the sample adequacy being defined along the routine screening and categorized as: satisfactory, satisfactory but presenting factors that might partially jeopardize the analysis, and unsatisfactory. results were stored in the epi-info 3.3.2 program. the χ2 test was used to compare altered results with the adequacy of the samples from cytopathological smears. differences with probability of rejection of the null hypothesis lower than 5% (p<0.05) were considered as significant. results: from 10,951 smears, 51.1% were classified as having satisfactory adequacy for analysis, 46.6% as satisfactory, but presenting some limiting factors, and 2.3%, as unsatisfactory. the main factors which have partially jeopardized the analysis were: lack of endocervical cells (52.2%), dried smears (22.8%), purulence (14.9%), or smears with some thick areas (9.5%). there was a higher rate of altered smears when the sample had been classified as satisfactory for analysis and with representation of endocervical cells asc-us (2.3%), asc-h (0.6%), lsil (3.2%), hsil (1.7%) and 0.3% of agc. differences were significant when p=0.001. the rate of low and high grade lesions was higher when the smears were satisfactory for analysis. conclusions: the rate of precursor uterine cervix cancer lesions varies according to the sample adequacy, and the main adequacy limit

Abstract: purpose: to verify whether women with atypias of undetermined significance and precursor lesions or invasive cervical outcomes were referred to medium complexity units (mcu) following the guidelines recommended by the brazilian ministry of health. methods: retrospective study based on the cytopathological outcomes of users of the unified health system, seen at basic health assistance units (bhau) and referred to mcus in the municipality of goiania, state of goiás, from 2005 to 2006. we assessed 832 records according to the recommendations of the brazilian ministry of health, as established by the brazilian nomenclature for cervical cytopathologic outcomes and recommended clinical practice. to check the distribution of variables such as reasons for referral, results of colposcopy and histopathology and clinical procedures we calculated absolute and relative frequencies, mean, minimum and maximum values. results: we understood 72.7% of the referrals were not in accordance with the recommendations of the ministry of health. there were 605 women with test results classified as atypical squamous cells of undetermined significance, possibly non-neoplasms, and squamous intraepithelial lesion of low level which were sent to mcu, and of these 71.8% were submitted to colposcopy, and 64.7% had histopathological examination which results were classified as 31.0% with non-neoplasms and 44.6% as nic i. out of 211 women with results classified as more severe squamous lesions, 86.3% were submitted to colposcopy and 68.7% of these had histopathological examinations. conclusions: the results of this study revealed high rates of inappropriate referrals to mcu, which required a high percentage of unnecessary procedures. the recommendations of the ministry of health were followed by bhau and the majority of women received counseling/treatment as recommended.

Guimar?es, Janaína Valadares;Costa, Roberto Silva;Machado, Benedito Honório;Reis, Marlene Ant?nia dos;
Revista do Instituto de Medicina Tropical de S?o Paulo , 2004, DOI: 10.1590/S0036-46652004000100012
Abstract: the manifestations caused by africanized bee stings depend on the sensitivity of the victim and the toxicity of the venom. previous studies in our laboratory have demonstrated cardiac changes and acute tubular necrosis (atn) in the kidney of rats inoculated with africanized bee venom (abv). the aim of the present study was to evaluate the changes in mean arterial pressure (map) and heart rate (hr) over a period of 24 h after intravenous injection of abv in awake rats. a significant reduction in basal hr as well as in basal map occurred immediately after abv injection in the experimental animals. hr was back to basal level 2 min after abv injection and remained normal during the time course of the experiment, while map returned to basal level 10 min later and remained at this level for the next 5 h. however, map presented again a significant reduction by the 7th and 8th h and returned to the basal level by the 24th h. the fall in map may contribute to the pathogenesis of atn observed. the fall in map probably is due to several factors, in addition to the cardiac changes already demonstrated, it is possible that the components of the venom themselves or even substances released in the organism play some role in vascular beds.

Revista Eletr?nica de Enfermagem , 2007,
Abstract: O Exame citopatológico é o método de triagem que auxilia na detec o precoce do cancer e de les es pré-cancerosas da cérvix. No Brasil, o cancer cervical representa a segunda neoplasia maligna mais incidente em mulheres. O objetivo desse estudo foi avaliar a freqüência das altera es citopatológicas de acordo com a faixa etária. A sele o dos casos foi realizada através dos resultados dos exames citopatológicos, de mulheres na faixa etária entre 14 a 80 anos, obtidos no Centro de Aten o Integrada à Saúde da Mulher, Uberaba (MG), no período de 2001 a 2003. Dos 35.220 resultados obtidos, em 3,34% foram descritos altera es no epitélio cérvico-vaginal, sendo mais freqüentes as altera es escamosas e glandulares de significado indeterminado (53,7%) e as infec es pelo HPV (31%). As mulheres mais jovens (< 40 anos) foram significativamente mais acometidas por essas altera es (p<0,005). Neoplasias invasivas acometeram 5,6% das mulheres a partir da quarta década de vida (p<0,005). Os diagnósticos das altera es no epitélio cérvico-vaginal de acordo com a faixa etária das mulheres foram semelhantes aos descritos na literatura, sendo que infec o pelo HPV, principal agente potencialmente carcinogênico, acometeu mulheres mais jovens e as neoplasias invasivas foram mais freqüentes a partir da quarta década de vida.

Amado, Janaína;
História, Ciências, Saúde-Manguinhos , 2000, DOI: 10.1590/S0104-59702000000500004
Abstract: based in large part on new documentation, recently uncovered in archives and libraries in portugal, the text focuses on a topic in the history of colonial amazon that has received very little attention to date: the presence of a large number of banished portuguese, sent to the region from portugal itself, from different parts of brazil, and from other portuguese colonies. in many ways, these banished individuals had an important effect in the amazon through 1822. the article points up portugal?s complex policy of banishment and the diversity of these individuals? experiences and their social roles in the amazon.
Advérbios modalizadores discursivos, advérbios de comentário avaliativos ou palavras modais?: um estudo comparativo das descri??es gramaticais do item lexical advérbio em português e alem?o
Salgado, Janaína Lopes;
Pandaemonium Germanicum , 2012, DOI: 10.1590/S1982-88372012000100009
Abstract: the aim of this article is to present contrastively the different types of grammatical categorization of the lexical item adverb in a brazilian and in two german grammars. it points out the complexity of describing the adverb as a unique grammatical class due to its heterogeneous nature. three types of grammatical categorization were chosen to illustrate this complexity: discursive modal adverbs (castilho 2010), comment adverbs (duden 2006) and modal words (helbig & buscha 2001).
