ABSTRACT

O estudo de estabilidade de fármacos e medicamentos, descrito pela resolução RE nº1/05 ANVISA determina a quantificação dos produtos de degradação, assim comoo método analítico utilizado correspondente. Como consequência, gerou-se a publicação do Informe Técnico nº 1/2008, com o objetivo de esclarecer procedimentos a serem realizados, nos casos em que a impureza ou padrões dos produtos de degradação não estão disponíveis. Diante das novas exigências, o delineamento do estudo torna-se uma das grandes dificuldades de sua realização, desafiando profissionais da área de desenvolvimento de produtos farmacêuticos.


The stability testing of drugs and medicines, as described in ANVISA resolution RE 1 / 05, specifies the quantitation of degradation products, as well as the analytical method concerned. As a consequence, Technical Report 1/2008 was published, with the aim of clarifying the procedures to be followed in cases where the impurity or patterns of degradation products are not available. In light of the new requirements, the study design constitutes one of the hardest problems for their implementation, facing professionals with new challenges in the area of pharmaceutical product development.

ABSTRACT

Meningitis is a common evolution in progressive disseminated histoplasmosis in children, and is asymptomatic in many cases. In leukemia, the impaired of the T cells function can predispose to the disseminated form. The attributed mortality rate in this case is 20 percent-40 percent and the relapse rate is as high as 50 percent; therefore, prolonged treatment may be emphasized. We have described a child with acute myeloid leukemia (AML), that developed skin lesions and asymptomatic chronic meningitis, with a good evolution after prolonged treatment with amphotericin B deoxycholate followed by fluconazole.

ABSTRACT

The duration of the parasitic phase of Dermatobia hominis and the clinical changes of artificially infested cattle with this parasite larvae have been studied. A group consisting of six artificially infested animals with 60 newly hatched D. hominis larvae (L) per animal, as well as a control group of six animals, were used. The two groups of animals were weekly accompanied, until the 63nd day after the infestation (DAI), being evaluated the values of the rectal temperature and heart and respiratory rates. For occasion of the 7th DAI, it was already possible to observe the parasitic nodules in the subcutaneous tissues of the infested animals. With the larval development, these nodules reached about 2 to 3 cm of diameter, and the duration of the parasitic phase ranged from 33 to 41 days. In relation to the clinical parameters studied (rectal temperature, heart and respiratory rates), there were no significant differences (P>0,05) between the averages of infested group and control group, during the study period. The variations of the rectal temperature values showed, during the whole experimental period, unside of the normality limits. It was also verified in the infested and control animals a significant Pearson coefficient (r=0,89 <0,01) between the values of the respiratory rate and room temperature

ABSTRACT

The period pupal stage of dermatobia hominis has been studied from third instar larvae, extracted from cattle, under ambient temperature conditions. Emergency of adults of D. hominis ranged from 6,7 percent to 42,9 percent. The pupal stage duration ranged from 23 to 37 days, with average of 27,4 days. The average duration of this stage (27,0 days), in males, was significantly lower (P<0,01) than the females (27,7 days). It has been showed a significant Pearson correlation (r=-0,90, P<0,01) between pupal stage duration and minimum and maximum temperatures averages

ABSTRACT

Em estudo aberto, nao comparativo, envolvendo quatro centros, 116 criancas e adolescentes portadores de infecoes cutaneas foram avaliados. Destes 68 eram do sexo masculino e 48 do sexo feminino, com idades entre 21 a 15 anos. O tratamento consistiu da administracao de bactroban creme (mupirocina,2 por cento) tres vezes ao dia, por um periodo nao menor que 5 dias .Impetigo foi o diagnostico mais comum em infecoes primarias enquanto escoriacao infectada foi mais prevalente em infeccoes secundarias de pele. O germe mais frequente foi Staphylococcus aureus. A duracao media do tratamento foi de 7,35 dias,ocorrendo cura do processo infeccioso em 106 pacientes (91,38 por cento) melhora em 9 pacientes (7,76 por cento) e insucesso em apenas 1 paciente (0,86 por cento). Os resultados confirmam ser o bactroban creme (mupirocina,2 por cento)um excelente antibiotico topico para o tratamento de infeccoes cutaneas em crianca e adolescentes.

ABSTRACT

Samples of Schistosoma mansoni soluble adult worm proteins (SWAP) were iodinated with 4-15 µmolI/mg protein using iodine monochloride. The capacity to elicit immediate hypersensitivity reactions of the iodinated derivatives was compared to that of the native SWAP preparations. The degranulation of mast clls from infected mice decreased with increasing iodine incorporation and was absent in fully iodinated samples containing 15 µmol I/mg protein. The response of guinea pigs and humans to the intradermal test with iodinated SWAP also decrease in proportion to iodine incorporation, and no responses were obtained with fully iodinated samples. No false-positive tests were observed. Antibodies to the folly iodinated extracts generated in C57BL/10 mice reacted by ELISA with the unmodified proteins and by immunoprecipitation on agar gel. The immunoprecicpitation pattern suggested that some epitopes were altered by iodination

ABSTRACT

Os soros de 472 brasileiros, confirmados como sendo positivos ou negativos em relacao a presenca de anticorpos anti-HIV e compreendendo todo o espectro clinico da infeccao, foram utilizados na avaliaco de seis ensaios imunoenzimaticos comerciais (ELISA), bem como de quatro testes alternativos tais como imunofluorescencia indireta (IFI), hemaglutinacao passiva (HP), dot blot e Karpas AIDS cell test. As sensibilidades variaram de 100 por cento (ELISA Abbott e Roche) a 84,2 por cento (HP) e as especificidades variaram de 99,3 por cento (IFI) a 80,2 por cento (HP). A sensibilidade e especificidade da HP e a sensibilidade do Karpas AIDS cell test foram significativamente menores que os outros ensaios. Embora a IFI e o dot blot tivessem apresentado uma boa sensibilidade e especificidade, os ensaios imunoenzimaticos (ELISA) foram mais adequados para serem utilizados em triagem quando outros parametros tais como facilidade de leitura e interpretacao dos resultados e duracao dos ensaios foram considerados

ABSTRACT

The occurrence of intestinal parasites, its relation with the transmission mechanism of HIV, and the clinical state of the AIDS patients, were analyzed in 99 Group IV patients (CDC, 1986), treated at "Hospital Universitário Pedro Ernesto" (HUPE), between 1986 and 1988. The group consisted of 79 (79.8%) patients whose HIV transmission mechanism took place through sexual contact and of 16 (20.2%) who were infected through blood. Feces samples from each patient were examined by four distincts methods (Faust et al, Kato-Katz, Baermann-Moraes and Baxby et al.). The moste occuring parasites were: Cryptosporidium sp., Entamoeba coli and Endolimax nana (18.2%), Strongyloides stercoralis and Giardia lambia (15.2%). E. histolytica and/or E. hartmanni (13.1%), Ascaris lumbricoides (11.1%) and Isospora belli (10.1%). Furthermore, 74.7% of the patients carried at least one species. Intestinal parasites were found in 78.5% of the patients who acquired the HIV through sexual intercourse and in 56,3% of those infected by blood contamination. The difference, was not statistically significant (p > 0.05). In the group under study, the increase of the occurrence of parasitc infections does not seem to depend on the acquisiton of HIV through sexual contact. It appears that in developing countries, the dependancy is more related to the classic mechanisms of parasites transmission and its endemicity

ABSTRACT

Os autores revisam 80 pacientes comprovadamente portadores de pancreatite aguda.Deste total, 44(55,0%) foram tratados clinicamente e 36 (45,0%) submetidos a tratamento cirurgico. O tratamento clinico foi eficaz em 86,4% dos casos, e o tratamento cirurgico apresentou resultados satisfatorios em 75,0% dos casos. As complicacoes precoses mais frequentes foram o choque (12,5%) e a insuficiencia respiratoria (10,0%). A mortalidade global da serie foi de 20,0%. Dos 16 obitos constatados, 12 (75,0%) ocorreram nas formas necro-hemorragicas e 4 (25,0%) nas formas edematosas da doenca. Concluiu-se que embora seja uma patologia prodominantemente clinica, a pancreatite aguda, para ser de evolucao favoravel, requer cuidados intensivos permanentes e uma vigilancia medica constante visando detectar as mudancas do seu curso evolutivo e permitir a indicacao adequada do momento e da forma do tratamento cirurgico

ABSTRACT

Num periodo de 12 anos, 117 pacientes com mais de 70 anos de idade foram tratados no Hospital Souza Aguiar, Rio de Janeiro, com hemorragia digestiva alta. Foram operados somente 36 doentes. A mortalidade global foi de 47%. Mortalidade cirurgica: 47,2%.Mortalidade com tratamento clinico: 46,9%.A alta mortalidade foi devida a 1) pessimo estado geral dos pacientes ao serem trazidos ao Hospital; 2) patologia associada, muitas vezes tendo a hemorragia como seu estagio final; 3) atitude pouco agressiva dos clinicos e cirurgioes em relacao ao tratamento do velho. Propomos uma atitude mais agressiva quer dos medicos e cirurgioes, quer dos proprios doentes e de suas familias no sentido de dar ao velho uma oportunidade de tratamento, que nos parece lhes vem sendo dificultado por razoes que a medicina moderna nao pode mais aceitar
