As interações medicamentosas (IM) são consideradas um problema de saúde pública, pois podem causar resultados negativos à saúde dos usuários de medicamentos. Portanto o referido trabalho teve como objetivos: estimar a prevalência de internações hospitalares relacionadas a Potenciais IM (PIM); identificar os sinais e sintomas, e os fatores de risco para a hospitalização relacionados à PIM. Metodologia: Realizou-se estudo transversal na clínica geral de um hospital privado do interior de São Paulo (Brasil), em maio de 2006, com pacientes acima de 18 anos, com tempo de hospitalização superior a 24horas, sendo os mesmos entrevistados sobre os sintomas/motivos de internação e os medicamentos que haviam utilizado previamente à hospitalização. Calculou-se Odds-ratiopara identificar fatores de risco, sendo encontrado os seguintes resultados: 168 pacientes utilizando mais de um medicamento, dos quais 57 apresentaram PIM, sendo que em 17(10,1%), os sinais e sintomas da PIM possivelmente foram a causa da hospitalização. A maioria das manifestações clínicas das PIM foram sintomas cardiovasculares (44,3%), gastrintestinais (17,2%) e musculoesqueléticos (13,8%) e 10% das PIM foram consideradas potencialmente perigosas. Não foram detectados fatores de risco relacionados ao gênero, idade, uso de medicamentos de estreita faixa terapêutica para hospitalização por PIM. A polimedicação foi fator de risco para ocorrência de PIM (p < 0,0001) opostamente ao aumento da idade que revelou ser um fator de proteção (p=0,02). Conclusão: Se faz necessário seguimento farmacoterapêutico de pacientes que utilizam fármacos de estreita faixa terapêutica, pois estas substâncias estão frequentemente envolvidas em IM perigosas. Palavras-chave: Problema relacionado ao medicamento. Resultado negativo associado ao medicamento. Erros de medicação. Interações de medicamentos.

Investiga-se a equação de Schrödinger unidimensional com uma classe de potenciais V(|x|) que se anulam no infinito e apresentam singularidade dominante na origem na forma α/|x|β(0 < β < 2). A hermiticidade dos operadores associados com quantidades físicas observáveis é usada para determinar as condições de contorno apropriadas. Dupla degenerescência e exclusão de soluções simétricas, consoante o valor de β, são discutidas. Soluções explícitas para o átomo de hidrogênio e o potencial de Kratzer são apresentadas.

Brainstem auditory evoked potential (BAEP) reflects the electrical activity along the auditory pathway, from the cochlea to the brainstem, and contributes for the diagnosis of deafness in dogs. BAEP recording may require chemical restraint in some cases, so this study was designed to analyze the impact of sedation with morphine and acepromazine on the BAEP recordings of 16 dogs with normal hearing. BAEPs were recorded before and during sedation with a combination of morphine (0.5mgkg(-1)) and acepromazine (0.05mgkg(-1)) given intramuscularly. The protocol employed allowed safe and effective animal restraint. Sedation increased the latency of waves II and III and intervals I-III and I-V but did not interfere with wave identification. and showed to be safe in the dogs tested. Based on the current literature this is the first study which assessed the impact of sedation on BAEPs in dogs in Brazil.

Pyrostegia venusta (Ker-Gawl.) Miers (Bignoniaceae) is a species with a wide distribution in nearly all of Southern and Southeastern Brazil, has long been used in folk medicine and is considered an invasive plant. The phytotoxic potential of a hydroalcoholic extract of the flowers of P. venusta was evaluated by the germination (pre and post-emergence) and the phytotoxicity bioassays (mitotic index) on the test plant Lactuca sativa (Asteraceae) (lettuce). A phytochemical screening was performed to identify the components of the floral extract. Different concentrations of the extract caused changes in the germination parameters, the root length and the mitotic index. The phytochemical screening indicated the presence of substances such as terpenes, sterols, flavonoids, tannins and saponins, which are compounds that may be associated directly with the results of cytotoxicity and phytotoxicity observed. P. venusta has allelochemical components capable of impairing the germination and root growth of lettuce.

The Auditory Evoked Middle Latency Response is one of the most promising objective tests in audiology and in revealing brain dysfunction and neuro-audiologic findings. The main advantages of its clinical use are precision and objectivity in evaluating children. This study aimed to analyze the auditory evoked middle latency response in two patients with auditory processing disorder and relate objective and behavioral measures. This case study was conducted in 2 patients (P1 = 12 years, female, P2 = 17 years old, male), both with the absence of sensory abnormalities, neurological and neuropsychiatric disorders. Both were submitted to anamnesis, inspection of the external ear canal, hearing test and evaluation of Auditory Evoked Middle latency Response. There was a significant association between behavioral test and objectives results. In the interview, there were complaints about the difficulty in listening in a noisy environment, sound localization, inattention, and phonological changes in writing and speaking, as confirmed by evaluation of auditory processing and Auditory Evoked Middle Latency Response. Changes were observed in the right decoding process hearing in both cases on the behavioral assessment of auditory processing; auditory evoked potential test middle latency shows that the right contralateral via response was deficient, confirming the difficulties of the patients in the assignment of meaning in acoustic information in a competitive sound condition at right, in both cases. In these cases it was shown the association between the results, but there is a need for further studies with larger sample population to confirm the data.

Purpose: To study the components of long latency auditory evoked potentials and to compare data from these measures in students with and without learning disabilities. Method: Thirty students, 15 with learning disorder (study group) and 15 typical without learning problems (control group), of both genders, aged 7-14 years, mean age 10 years. They underwent clinical assessment in a clinic belonging to a public university in the state of São Paulo. Following, audiological assessment was performed to determine normal peripheral auditory system and electrophysiological assessment by examining the long latency auditory evoked response. Result: The results showed that there are functional differences between the groups. Increased latency components of long latency auditory evoked potential was observed in the study group compared to the control group. Longer latency values of these components were observed in the left ear when stimulated in the study group. Conclusion: This study contributed to better understanding of the auditory pathway functioning in children with learning disorders and can be a reference for other clinical and experimental studies and thus improve the definition of diagnostic criteria in this population.

In the last twenty years, and more expressively in the past decade, the search for improvement in the organ transplantation system has contributed to the achievement of positive results in the Brazilian statistics related to the survival of transplanted individuals. However, for a transplantation to be performed, a number of phases must be followed by professionals working in organ search services. The phase that generates the greatest tension is undoubtedly that of family interviews, as it involves both the feelings of relatives who are facing a recent loss and those of interviewers who need to know how to deal with families at this time. The goal of this study was to apprehend perceptions of professionals working for an Organ Search Organization concerning interviews with relatives of potential donors. The qualitative methodology was used by adopting the Collective Subject Discourse for data organization. Interviews were conducted with six staff members of an organ search service whose experience as interviewers comprised from eight to fourteen years of work. It was possible to apprehend the professionals’ perceptions of family interviews and identify facilitating and hindering factors in this phase of the donation process. Such factors mainly involve: contact with the teams assisting patients, the difficult moment that families are experiencing and the teams’ as well as the institution’s preparation for rendering this type of service. The balance between the offer of and demand for organs in Brazil will only be achieved by means of an efficient and effective structure in transplantation organ search services and increased donation consent rates to be obtained by adequate communication between interviewers and relatives

A preocupação ambiental em relação aos resíduos de equipamentos elétricos e eletrônicos (REEE) vem crescendo muito nos últimos anos devido à presença de substâncias perigosas que podem causar danos ao ambiente e à saúde. O trabalho teve por objetivo investigar o destino de REEE gerados no Campus Quadrilátero da Saúde/Direito (CQS/D) da Universidade de São Paulo (Faculdade de Medicina, Faculdade de Saúde Pública, Escola de Enfermagem, Instituto de Medicina Tropical e Faculdade de Direito), a partir do momento em que os mesmos deixam as dependências da Instituição e identificar potenciais riscos à saúde e ao ambiente, decorrentes das atuais ações de gerenciamento dos REEE nas unidades estudadas. A pesquisa desenvolveu-se em 3 etapas: a) pesquisa bibliográfica e documental; b) visitas às unidades que compõem o CQS/D, e identificação de cinco intituições filantrópicas como principais destinos; c) visitas aos locais identificados para investigar as atividades desenvolvidas para a recuperação de equipamentos, componentes ou materiais recicláveis, com base em um formulário desenvolvido. Adicionalmente, foram realizadas visitas a outros quatro locais de destino de REEE. Foi identificado que as etapas realizadas nas instituições são: recebimento, teste, conserto e desmontagem manual e que o destino dos REEE pode ser considerado problemático, já que os rejeitos acabam sendo descartados como resíduo comum, podendo causar danos ao ambiente e à saúde. Além disso há riscos ocupacionais, pois os trabalhadores, além de não utilizarem equipamentos de proteção individual necessários, nem sempre recebem capacitação para exercer suas funções
