How accurate is ultrasound in evaluating palpable breast masses?
MA Gonzaga
Pan African Medical Journal , 2010,
Abstract: Introduction: Breast masses have become common in women. Such masses pose a potential threat to women especially in the era of increased cases of breast cancer worldwide. Breast carcinoma ranks first among the malignant tumors affecting females in many parts of the world with the rate of breast cancer being 1 in 8 in USA. There are currently more than 600 000 cancer deaths annually in Africa. By 2020, 70% of the 15 million new annual cancer cases will be in developing countries. Ultrasound is a relatively inexpensive and readily accessible imaging modality that can be utilized in the evaluation of clinically palpable breast masses. The purpose of this study was to find out the accuracy of ultrasound in the diagnosis of palpable breast masses. Methods: Eighty palpable breast masses were evaluated at ultrasound and information about the characteristic features of the masses was recorded. An impression about the diagnosis was made and results were correlated with histology findings. Results: The overall sensitivity of ultrasound in detecting breast lumps was 92.5%. The sensitivity and specificity of ultrasound for detecting breast carcinoma was 57.1% and 62.8% respectively with a positive predictive value of 68.1%, a negative predictive value of 99.5%, a positive likelihood ratio of 39 and a negative likelihood ratio of 0.07. Ultrasound reliably differentiated cystic from solid breast masses. Conclusion: Ultrasound is significant in differentiating cystic from solid breast masses. Ultrasound is also important in detecting suspicious breast masses and should therefore be used in the evaluation of symptomatic breast masses.
An exploratory study of the views of Ugandan women and health practitioners on the use of sonography to establish fetal sex
MA Gonzaga
Pan African Medical Journal , 2011,
Abstract: Introduction: Ultrasound is now part of routine care for pregnant women in Uganda, and is one of a range of techniques used in screening during pregnancy. However, it differs from most others screening procedures because it allows women to view their babies. Unfortunately, the recipients of this technology are seldom asked about it. This study aimed at finding out the knowledge, attitudes and practices of pregnant women towards prenatal sonography. Methods: The study was exploratory and descriptive, using interviewer-administered questionnaires. Thematic analysis was employed. Results: The health professionals interviewed discouraged the idea of disclosing fetal sex unless it is justifiably indicated for medical reasons. However, the women in this study supported the idea of being told the sex of the baby in order to plan for the necessary items they need. Conclusion: There is need for a policy to be made not to disclose fetal sex to parents as this raises numerous ethical concerns. Health workers, women and the general public need to be sensitized about the dangers of this practice as well.
Anomie and Isolation: The Wind-up Bird Chronicle, Ghost in the Shell, Serial Experiments Lain, and Japanese Consensus Society
Elmo Gonzaga
Humanities Diliman , 2002,
Abstract: The essay explores how the societal effects of Japan’s economic recession during the 1990s are reflected in several cultural texts from that period: Haruki Murakami’s novel The Wind-up Bird Chronicle, the animé film Ghost in the Shell and the animé series Serial Experiments Lain.Faced with sudden job uncertainty due to the recession, Japanese individuals accustomed to the ideology of progress of a society that values uniformity and conformity have fallen into listlessness and withdrawal. Accordingly, the protagonists of these texts all experience a crisis of embodied subjectivity, or shutaisei that is tied to a loss of community and history.They work to reconstitute their shutaisei by first uncovering their personal and collective history in the form of a coherent awareness of their past. Transcending their isolation, they likewise strive to develop bonds with others through reciprocal communication.Particularly because these texts are characterized by elements of the fantastic and narratives of metamorphosis, they can also be seen as allegories of subversion against Japanese consensus society and its ideology of progress.
Contribui??o ao conhecimento dos nematóides que causam galhas em raízes de plantas em S?o Paulo e estados vizinhos
Lordello, Luiz Gonzaga E.;
Anais da Escola Superior de Agricultura Luiz de Queiroz , 1964, DOI: 10.1590/S0071-12761964000100017
Abstract: eight root-knot nematode forms are known to occur in brazil, namely meloidogyne exigua, m. incognita, m. j. javanica, m. j. bauruensis, m. inornata, m. hapla, m. arenaria arenaria and m. coffeicola. after presenting a historical resume of the root-knot disease, as well as observations on symptoms, distribution and spread, and life history of the nematodes, a study of the morphological characters used in identification of species is made, a key for separating the forms referred to above being also prepared. as no information on host plants of the coffee root-knot nematode (m. exigua) was available, a few tests were performed, as an attempt to infect several plant species. pepper (capsicum annuun) was the only plant attacked by m. exigua, having failed all attempts to infect nine other plants, including tomato var. rutgers. m. exigua incited formation of galls on roots of cucumber, but no adult female was found in the tissue. in a final chapter dealing with control, a review of all methods available is presented.

Bragantia , 1956, DOI: 10.1590/S0006-87051956000100006
Abstract: one of the serious detriments to soybean (glycine max (l.) merr.) cultivation in the state of s. paulo, brazil, are root-parasitic nematodes. a study of infected material collected at bauru, where at least two distinct soybean varieties were cultivated, disclosed that three forms were involved: a meadow nematode (pralylenchus sp.) and two root-knot nematodes (meloidogyne incognita (kofoid & white, 1919) chitwood, 1949, and m. javanica bauruensis n. subsp.). silva, lordello & miyasaka (3) published some observations about the resistance of several soybean varieties to the attacks by root-knot nematodes in campinas. a detailed study of the nematodes involved in those experiments, which were considered as related do m. incognita, has not yet been made. one of the varieties tested, la 41-1219, proved to be resistant, thereby providing promising material for further studies and breeding. unfortunately, such a variety when planted in bauru, was severely attacked by a root-knot species, which is identified as m. incognita. attacks by m. javanica bauruensis was not noted in that variety but was noted in another variety (abura) growing adjacent in the same field. the host preference of those two nematodes was specific and very marked. m. incognita attacked only var. la 41-1219 and m. javanica bauruensis only var. abura. invasions by meadow-nematodes were equally observed in the two varieties concerned. in this paper, the study of m. javanica bauruensis n. subsp. is made with all the details possible. it differs from the typical subspecies (m. javanica javanica (treub, 1885) chitwood, 1949), in having : a) eggs usually wider (37.0-52.5 : 31.0-40.0 micra); 6) stylet of larvae somewhat longer (11.0-11.6 :10.0 micra); c) neck of larvae longer (b1 = 6.1-6.5 :b = 6.3-8.0); d) head of male with a single post-labial annule instead of the two or three present in the typical subspecies; e) lateral lines in the perineal pattern less evident and not extending to cervical region, with so
Conteúdos ideológicos da nova direita no município de S?o Paulo: análise de surveys
Alves, Maria Teresa Gonzaga;
Opini?o Pública , 2000, DOI: 10.1590/S0104-62762000000200002
Abstract: this article shows some evidences that the ideological content of the new right agenda is spread out amongst the public of the city of s?o paulo. such a particular phenomenon is further associated with a broader disposition, that is, the renewal of the right since the mid 1970s in advanced capitalist societies, and in brazil at large since the late 1980s. the electoral success of the right seems to be associated to its capacity to renew itself and to present its own interests as though social demands. this hypothesis was tested in surveys conducted in the city of s?o paulo in 1993 and 1995. the results of the first investigation indicate that the agenda of the more programmatic right is associated with the richer sectors of the society which, in general, support the neoliberal programme whilst being also anti-leftists. amongst the poorer sectors however, there is more sensitivity towards topics related to morality and authoritarism, as well as statism.
A partilha do trabalho e a demanda dinamica por trabalhadores e horas
Pereira, Rodrigo;Gonzaga, Gustavo;
Revista Brasileira de Economia , 2001, DOI: 10.1590/S0034-71402001000100001
Abstract: this paper investigates whether a reduction in standard hours has a positive impact on the employment level, an effect known in the literature as work-sharing. the innovation here is to include employment adjustment costs in the theoretical model. this feature introduces interesting dynamic aspects, which make it possible to study optimal paths of employment and average hours both in the short and the long run. the main result is that work-sharing does not occur even in the presence of employment adjustment costs.
