Schistosomus reflexus (SR) is a rare and fatal congenital anomaly, primarily observed in ruminants, presenting fetus with dorsiflexion of the vertebral column, exposure of thoracic and visceral organs, and scoliosis. A caesarian was performed on a Dorper sheep on a farm in Botucatu-SP and according to the general characteristics and findings observed in the necropsy of the fetus it was an SR case. The radiography indicated a marked ventro-dorsal deviation of the thoracolumbar column segment and deformity of the ribs. On the computed tomography the integrity of the bones and organs were detected, except for the absence of a lumbar vertebra. No data were available in the literature for SR diagnosis in sheep by image, so radiographic and tomographic exams of the fetus were done.

This study aimed to analyze how the families of cancer patients perceived the treatment provided at a specialist public outpatient clinic, using Bardin's method of Content Analysis. Seven families consisting of fourteen family members were interviewed. They underlined doctor-patient relationship, judging it to be impersonal and superficial, resulting in a lack of security and trust. Families try to to participate but feel undervalued and excluded from the care. Necessary information that they are not given is sought in the media, while comfort is achieved through religious or spiritual practices. Health care training must encourage professionals to view the family as a unit of care, aligning training to different modes of health care.

OBJECTIVE: to describe elderly mortality from cardiovascular and respiratory diseases and neoplasms in Marilia (SP). METHODS: this is a descriptive study of mortality from three diseases as defined by the 10th International Classification of Diseases, between 1998-2000 and 2005-2007. Mortality Information System records were used. Mortality rates by age and sex were calculated. RESULTS: circulatory diseases were the main causes of death among the elderly (39.25%). Neoplasm decline was noticed in both sexes and in those aged 60-69, particularly prostate cancer in men (-83.86%) and breast cancer (-70.96%) in this age group. Deaths from respiratory diseases increased in patients aged 80 and older: 39.31% in men and 57.92% in women. CONCLUSION: mortality from circulatory diseases and neoplasms among the elderly showed a decline, with increased mortality from respiratory system problems in patients 80 years of age and older.

Almost forty years computed tomography (CT) has been one of the most powerful tools in diagnostic imaging. However, this modality delivers relatively high doses to their patients. It is known that the inappropriate use and unnecessary radiation may be associated with a significant risk of cancer, especially in pediatric patients. Moreover, the quality assurance in CT, provided and required by Portaria 453/98 and the guide of the RE 1016/05, ensures that the images generated by computer tomography provide reliable diagnostic information with doses as low as reasonably achievable. This research aimed to make the quality control (QC) of CT equipment; establish a better relationship between dose and noise on the image to protocols of skull CT according to the study of optimization proposed in 2005 by Daros; and assess the dose distribution in different cranial organs for protocols of adult and pediatric use in the routine of the Department of Diagnostic Imaging of HCFMB-UNESP. The equipment used for testing QC, optimization and dosimetry was a third generation tomograph GE Sytec 3000i

O termo “câncer” corresponde ao conjunto de cerca de 100 doenças que têm em comum o crescimento desordenado de células que invadem os tecidos e órgãos, podendo metastatisar para outras regiões do corpo. Os tumores de mama e colo do útero são os mais frequentes no sexo feminino. Neste estudo, avaliou-se o efeito tóxico de injeções intratumorais de abrina e pulchelina com ou sem β-D-galactose sobre o desenvolvimento do tumor mamário murino, verificando sua influência sobre o sistema imune. Proteínas inativadoras de ribossomos (RIPs) abrina, obtida de sementes de Abrus precatorius, e pulchelina, de sementes maduras de Abrus pulchellus subsp. tenuiflorus, foram utilizadas e como droga controle foi usada a Doxorrubicina. As RIPs foram administradas em camundongos fêmeas Balb/c. A partir dos tumores retirados dos animais em estudo, verificou-se o percentual de inibição do crescimento tumoral, medindo-se o tamanho e os pesos dos tumore. A partir de culturas de macrófagos obtidos dos animais de estudo, avaliou-se a produção de NO, TNF-α e IL-12 pelas RIPs na presença ou ausência de β-D-galactose. A IL-10 foi quantificada a partir de linfócitos esplênicos. A viabilidade celular foi verificada quando as células foram sujeitas às ações das RIPs. Com base nos resultados obtidos, observou-se que as RIPs não apresentaram potencial antitumoral, pois não houve redução do tamanho do tumor em relação ao controle, exceto pela abrina (p<0,05). Contudo, verificou-se que houve um possível efeito inibitório da toxicidade de abrina e pulchelina pela galactose sobre as células tumorais. As substâncias testadas (abrina, pulchelina e doxorrubicina) nas concentrações utilizadas nos testes de citotoxicidade ...
