La organización del cuerpo académico: las premisas de decisión, colegialidad y respuesta grupal. Un acercamiento desde su autorreferencialidad. Estudio de caso comparativo en la educación de la ingeniería
Lobato Calleros, Odette;Garza, Eduardo De la;
Revista mexicana de investigación educativa , 2009,
Abstract: at present, the policies of higher education-growth, financing, training, planning, and evaluation-come together in academic bodies, due to the relevance of their response to the demands of knowledge. this study proposes using luhmann's perspective of autopoietic systems of decision-making to learn more about the organization of academic bodies and to compare that organization with the ideal state of policies. putting the perspective to test identifies, in a comparative historical case study of two academic bodies dedicated to engineering: a) a structure of premises of decision-making that tends to remain constant and that differentiates collegiality and the group response; and b) the behavior of each academic body as an autopoietic system of decision-making. the expectations suggested by these findings will need to be tested in other academic bodies.

Abstract: this study aimed to evaluate the adequacy of the hospital information system of the national unified health system (sih-sus) in identifying cases of rhd hemolytic disease of the newborn (hdn) at the fernandes figueira institute (iff/fiocruz) from 1998 to 2003. neonatal records, data from the medical archives, and aih (hospital admissions authorization form) data consolidated in the sih-sus were analyzed. cases were identified according to the following fields: principal diagnosis, secondary diagnosis, and procedure performed. during the period studied, 194 cases of hdn were diagnosed. the medical archives registered 148 newborns with hdn, however only 147 aihs were issued and 145 consolidated in the sih-sus. among these 145 cases, 84 cited hdn as the principal diagnosis, while secondary diagnosis identified 38 additional cases and the procedures performed failed to identify any further cases. thus, the sih-sus identified only 122 (62.9%) of the 194 cases of hdn treated at the iff/fiocruz. although it is necessary to evaluate other units, the sih-sus does not appear to be reliable for monitoring hdn. additional studies are essential for employing secondary administrative data in the context of epidemiological surveillance.

Abstract: this article aims to investigate the impact of the baby-friendly hospital initiative (bfhi) on exclusive breastfeeding (ebf). this was a cross-sectional study with 811 mothers of infants under five months of age, randomly selected at five health centers in rio de janeiro, brazil. the exposure variable was hospital of birth, categorized in accredited hospitals (bfh), certified hospitals (cbfh), and hospitals without accreditation. the data were analyzed by complementary log-log transformation models, which capture cohort longitudinal experience (current status data). even after adjusting the analysis for maternal socio-demographic, lifestyle, and psychological factors, health services use, and infants' age and health status, duration of ebf was longer in infants born in bfh and cbfh. the findings suggest the effectiveness of bfhi in maintaining ebf throughout the early months of life. to extend ebf through the first six months of life would require not only strengthening the bfhi but also developing and encouraging more actions in favor of breastfeeding, focusing on primary healthcare facilities.

Abstract: recently, reproductive factors have been studied in diffuse systemic sclerosis patients and pregnancy was not likely to be a risk factor for disease development. this findings need to be confirmed in the limited form of the disease. objective: to compare reproductive factors in 372 limited systemic sclerosis (lssc) and 240 rheumatoid arthritis (ra) pregnancies and their relative risk for developing lssc. methods: one hundred and seventeen lssc and 72 ra consecutive female patients were interviewed with a detailed questionnaire to estimate the relative risk of developing lssc given a relevant reproductive variable. the odds ratio (or) was calculated using as reference nulliparous women and no history of miscarriage. results: diagnosis of lssc and ra was made after pregnancy for most patients of both diseases (97% vs. 90%, respectively, p > 0.05). a similar mean age at diagnosis (40.8 years old vs. 38.4 years old) and mean age of first pregnancy (22.7 years old vs. 23.5 years old) were noted in lssc and ra (p > 0.05), respectively. the number of pregnancies/patient (3.1 vs. 3.3), percentage of patients ever pregnant (84.6% vs. 88.8%) and miscarriage (19.8% vs. 21.6%) was similar in both groups (p > 0.05). compared to nulliparous women, parous lssc had an or of 0.7, 95% ci 0.3-1.7 for developing lssc and, for women who experienced a miscarriage, the [or] was 0.9, 95% ci 0.5-1.6, compared with those lssc patients with no miscarriage. in addition to that, the number of pregnancies was not associated with an increased risk for lssc when compared to nulliparous controls. conclusions: these data suggest that the overall reproductive history of lssc is comparable to ra. moreover, it indicates that pregnancy is unlikely to account for an increased risk or a protective effect to develop lssc in comparison to ra.

Abstract: the objective of this trial was to evaluate the effect of weaning age on growth and carcass characteristics of calves from primiparous bos indicus x bos taurus crossbred cows. heifers were divided in two groups according to the order of access to pasture and rotationally grazed pastures of ryegrass (lolium multiflorum lam) and arrowleaf clover (trifolium vesiculosum cv. yuchi) from weaning until their first mating season (two winter/spring seasons); animals were then transferred to native pasture in the following summer-autumn season. calves were randomly assigned, according to breed and heifers grazing group order, to one of two weaning ages: early weaning (ew) - 07 calves weaned at 70 days of age with an average body weight of 83.2 kg or conventional weaning (cw) -10 calves weaned at 180 days of age and with an average body weight of 152.0 kg in a completely randomized design. steers were slaughtered with two years of age. heifers grazing group did not affect calves performance. calves in the cw treatment were heavier (202.1 kg) at one year old than those on ew (183.0 kg), but no significant difference was observed when animals were slaughtered at two years of age (cw=408.5 kg vs. ew=411.2 kg). carcass traits such as fat thickness, conformation, "hilton quote" classification, and hot yield did not differ comparing ew with cw steers. therefore, early weaning did not affect performance and carcass characteristics of steers slaughtered at two years of age.

Abstract: O papiloma invertido (PI) apresenta diversos tipos de tratamento cirúrgico. A abordagem endoscópica exclusiva tem se mostrado na última década como boa op o em rela o à abordagem externa. OBJETIVO: Descrever a amostra dos pacientes com diagnóstico de papiloma invertido, mostrar a experiência do servi o no manejo do tumor e comparar os dados com os da literatura. Forma do Estudo: Estudo de coorte histórica com corte transversal. MéTODO: Estudo retrospectivo dos prontuários de 17 pacientes operados em um servi o de Rinologia entre 2005 e 2011. Foram avaliados perfil epidemiológico, estadiamento de Krouse, via de acesso cirúrgico, maligniza o e recorrência pós-operatória e a correla o entre recidivas e estadiamento pré-operatório, via de acesso cirúrgico e maligniza o. RESULTADOS: Cinco (29,41%) dos pacientes foram classificados como estádio T2 de Krouse, nove (52,94%) como T3 e três (17,65%) como T4. Três (17,65%) pacientes apresentaram maligniza o e quatro (23,5%) recidiva. Onze pacientes (64,70%) foram submetidos à via endoscópica exclusiva, três (17,6%)à via combinada e três (17,6%) à via aberta. CONCLUS O: O acesso endoscópico exclusivo atualmente é um método n o só eficaz como também seguro para o tratamento dos estádios mais avan ados do PI. Inverted papilloma (IP) has several treatment avenues. The endoscopic approach in the last decade has proven to be a good option over the traditional approach. OBJECTIVE: Describe the epidemiological profile of patients with inverted Papilloma, describe our experience on managing this tumor and compare our data with the literature. Study Design: Cross-sectional, historical cohort. METHOD: Retrospective study of medical records of 17 patients treated for histopathologicallyconfirmed inverted papilloma between 2005 and 2011. We assessed patients age, gender, tumor side, symptoms, diagnosis, comorbidities and habits, Krouse staging, surgical approach, intraoperative and postoperative, and malignant postoperative recurrence and also the correlation between recurrence with preoperative staging, the surgical approach used, and the presence of malignancy. RESULTS: Five (29.41%) patients were classified as Krouse stage T2, 9 (52.94%) as T3 and 3 (17.65%) as T4. Three (17.65%) patients had malignancy and the recurrence rate was 23.5% (4 pacients). Eleven patients (64.70%) underwent endoscopic approach, 3 (17.6%) the combined aprroach (endoscopic assisted) and 3 (17.6%) external approach. CONCLUSION: The endoscopic approach is currently becoming a method not only effective but also safe for the treatment of more adv

Abstract: objective: to report oncological cases (excluding those related to breast cancer) for which radioguided surgery has been used in combination with the radioguided occult lesion localization technique. introduction: radioguided surgery enables a surgeon to identify lesions or tissues that have been preoperatively marked with radioactive substances. the radioguided occult lesion localization technique has been widely used to identify the sentinel lymph node and occult lesions in patients with breast cancer. however, few studies have reported the use of this technique for non-breast cancer pathologies. methodology: in all cases, injection of technecium-99m sulfur colloid was performed, directly inside or near by the suspicious lesion, guided by ultrasound or computed tomography, up to 36 hours prior to the surgical procedure. intraoperative lesion detection was carried out using a gamma-probe. results: we report five oncology cases in which preoperative markings of the lesions were carried out using the radioguided occult lesion localization technique. the patients presented with the following: recurrence of renal cell carcinoma, cervical recurrence of papillary carcinoma of the thyroid, recurrence of retroperitoneal sarcoma, lesions of the popliteal fossa, and recurrence of rhabdomyosarcoma of a thigh. in each case, the lesions that were marked preoperatively were ultimately successfully excised. conclusions: radioguided surgery has proven to be a safe and effective alternative for the management of oncology patients. the radioguided occult lesion localization technique can be useful in selected cases where suspect lesions may be difficult to identify intraoperatively, due to their dimensions or anatomical location. the procedure allows for more conservative excisions and reduces the surgery-related morbidity.
Aspectos parasitários observados no local inoculado com esporozoitos de Plasmodium Gallinaceum
Paraense, Lobato;
Memórias do Instituto Oswaldo Cruz , 1943, DOI: 10.1590/S0074-02761943000300004
Abstract: the following is a summary of the studies made on the development of plasmodium gallinaceum sporozoites inoculated into normal chicks. initially large numbers of laboratory reared a?des aegypti were fed on pullets heavily infected with gametocytes. following the infectious meal the mosquitoes were kept on a diet of sugar and water syrup until the appearance of the sporozoites in the salivary glands. normal chicks kept in hematophagous arthropod proof cages were then inoculated either by bite of the infected mosquitoes or by subcutaneous inoculations of salivary gland suspensions. by the first method ten mosquitoes fed to engorgement on each normal chick and were then sacrificed immediately afterwards to determine the sporozoite count. by the second method five pairs of salivary glands were dissected out at room temperature, triturated in physiological saline and inoculated subcutaneously. the epidermis and dermis at the site of inoculation were excised from six hours after inoculation to forty eight hours after appearance of the parasites in the blood stream and stretched out on filter paper with the epithelial surface downward. the dermis was then curretted. slides were made of the scrapings consisting of connective tissue and epithelial cells of the basal layers which were fixed by metyl alcohol and stained with giemsa for examination under the oil immersion lens. skin fragments removed from normal chicks and from regions other than the site of inoculation in the infected chicks were used as controls. in these, only the normal histological aspect was ever encountered. in the biopsy made at the earliest period following inoculation clearly defined elongated forms with eight or more chromatin granules arranged in rosary formation were found. the author believes these to be products of the sporozoite evolution. search for transition stages between these forms and sporozoites is planned in biopsies to be taken immediately following inoculation and at given intervals u
