ABSTRACT

AIM: To investigate the influence of hypotonic parenteral hydration on serum and urinary sodium and osmolality in infants with moderate bronchiolitis. METHODS: We studied 36 infants (mean age 3.7 ± 2.3 months), with a diagnosis of moderate bronchiolitis admitted to a paediatric emergency unit in São Paulo, Brazil. Patients received a standard parenteral hypotonic solution, according to Holliday and Segar, during the first 24 h, due to respiratory distress. The disease was monitored by a respiratory severity score (RDAI-Respiratory Distress Assessment Instrument), respiratory rate and oxygen saturation. Serum and urinary sodium and osmolality were monitored at admission, 24 and 48 h after admission. RESULTS: All respiratory parameters improved during hospitalisation. Serum sodium and osmolality dropped after 24 h (136.8 ± 2.8 and 135.8 ± 2.6 mEq/L, p = 0.031; 283.4 ± 4.1 and 281.6 ± 3.9 mOsm/kg, p = 0.004 respectively) as well as urinary osmolality (486.8 ± 243.4 mOsm/kg and 355.7 ± 205.0 mOsm/kg, p < 0.001) when compared to admission. CONCLUSION: This study reinforces the occurrence of hyponatraemia in bronchiolitis even in patients with moderate disease and highlights the risk of serum sodium drop caused by hypotonic parenteral hydration.

ABSTRACT

Na prática diária, uma emergência médica, além de ser freqüente, é geralmente complexa e grave. O plantonista do pronto-socorro está quase sempre sozinho e, geralmente, não há tempo para acessar um serviço informatizado de ajuda ou um colega mais experiente. Também não há muito tempo para pensar e as decisões devem ser rápidas e eficazes, apesar da pressão por um bom resultado ser muito grande. Por isso é importante e até básico ter uma formação sólida. Daí o grande mérito deste livro. Escrito por especialistas com vasta experiência, fornece de maneira objetiva e bem embasada as informações necessárias para permitir um atendimento adequado dos pacientes que procuram o pronto-socorro. Além disso, considerando a carga emocional bem conhecida pelos profissionais que atuam nesses serviços (sofrimento do paciente, angústia dos pais e familiares, ambiente tneso, muitas vezes frenético), a boa capacitação do médico contribuirá para uma melhor tomada de decisão. O livro não é apenas útil, é indispensável. Será certamente o companheiro do pediatra em muitos plantões e muitas jornadas

ABSTRACT

Objetivo: Avaliar a freqüencia diagnóstica dos vários distúrbios causadores de hematúria na criança em um serviço universitário de Nefrologia Pediátrica. Métodos: Foram anlisados retrospectivamente os prontuários de 128 crianças, 78 do sexo masculino e 50 do sexo feminino, que apresentavam como queixa / achado principal de hematúria macroscópica persistente, no período de 1978 a 1995. A análise foi realizada com especial atençäo a dados de história, exame físico e antecedentes pessoais e familiares. A idade média à 1ª avaliaçäo foi de 8,2 anos (5 meses a 16 anos), o período médio de seguimento de 3,2 anos (1 mês a 15 anos). Foram excluídos casos que abandonaram o seguimento antes da investigaçäo etiológica. Resultados: Hematúria macroscópica ocorreu em 104 pacientes e microscópica persistente em 24 crianças. Entre os diagnósticos etiológicos firmados predominaram os distúrbios metabólicos e a litíase das vias urinárias, isoladas ou em associaçäo (total de 65,5 por cento dos casos). Hipercalciúria foi o distúrbio metabólico predominante (90,1 por cento), isoladamente (73,2 por cento) ou em associaçäo com hiperuricosúria (16,9 por cento). Antecedentes familiares positivos para litíase foram encontrados em 32,1 por cento das casos diagnosticados como portadores de litíase e/ou distúrbios metabólicos urinários...

ABSTRACT

Synopsis A preoccupation with aesthetics and a real desire for social development has brought about an increase in the demand for safe, effective depigmenting products among African and Asian populations. For many years now, we have used an experimental model which uses the black mouse CS BL/6/JICO. As a result of developing needs and the necessity to check the results obtained from animals on humans, we have had to change the methodology in order to take into account the specific characteristics of human skin. After a summary of the protocol used on the mouse, here you will find a description of the technical changes which had to be made in order to carry out the study on humans. The results of a comparative test between the two models are given. This was carried out with a cosmetic preparation containing 2% hydroquinone introduced via a vector that facilitates its absorption. The depigmentation observed in the animal model was not found significant in humans. Taking into consideration the large number of differences between individuals, and in order to demonstrate a significant result on humans, it would be necessary to use a larger experimental group, treated for a longer period than that normally used with animals.

ABSTRACT

Os achados radiológicos na infecçäo urinária de repetiçäo em 53 crianças säo apresentados. Os autores chamam a atençäo para os riscos potenciais de acometimento pielonefrítico na vigência de determinadas patologias, particularmente uropatias obstritivas a refluxo vésico-ureteral primário moderado e grave. Enfatizam a necessidade de diagnóstico da infecçäo urinária na criança, bem como de identificaçäo de alteraçöes radiológicas passiveis de tratamento clínico e/ou cirúrgico, que tragam maior risco de comprometimento do parênquina renal

ABSTRACT

The serum levels of thyroid hormones (T3, F.T3, RT3, T4 and F.T4), cholesterol and triglycerides were measured in a population of adult male rats subjected to experimental fasting. Comparison of bindings with results published in the literature reveals certain disagreements attributable to individual variations in the animals resulting from physical or physiological factors. This study demonstrates that deiodination of thyroxine in T3-Reverse has an economic role on a metabolic level. Evaluation of the T3/RT3 ratio appears to provide an indication of the homogeneity of the peripheral metabolism in an experimental population.

ABSTRACT

A radioimmunoassay technique using a double antibody procedure for human serum thyroglobulin (HTg) is described. Only antigen labeling with iodine-125 is performed extemporaneously, the other reagents being purchased commercially. Quality criteria were: sensitivity (2 microgram/l), interassay reproducibility (coefficient of variance, C.V. = 11%) and specificity are comparable with those of previously published techniques. Normal limits for serum HTg concentrations were established on the basis of 65 assays (33.0 +/- 21.20 microgram/l). In 69 subjects exhibiting goiters and cold nodules, the values observed were considerably higher and more dispersed (81 +/- 57 microgram/l); the same observation was made for the the cases of Basedow's disease studied. Patients who had undergone thyroid ablation for thyroid cancer exhibited a low or nondemonstrable HTg concentration, except for seven subjects showing osseous and/or pulmonary functionally active metastases of a differentiated cancer whose HTg levels were significantly higher (300-400 microgram/l). These results concur with several previous reports in emphasizing the interest of assaying serum HTg during the surveillance of differentiated cancers of the thyroid.
