Estudo da estabilidade acelerada de solução oral de paracetamol 200mg/mL, distribuída no Sistema Único de Saúde - SUS

O paracetamol é um fármaco de ação analgésica e antipirética, obtido através da metabolização da fenacetina, um analgésico derivado do alcatrão. Seu mecanismo de ação consiste em inibir a enzima responsável pela síntese de prostaglandina no cérebro, reduzindo a febre e induzindo a analgesia. O objetivo desse trabalho foi avaliar as possíveis alterações físicas e químicas da solução de paracetamol distribuída pelo Sistema Único de Saúde (SUS) por meio do estudo de estabilidade acelerada. Cada amostra foi armazenada em condições ambientais diferentes e foi analisada no momento inicial, após 60 dias e após 90 dias. As amostras foram examinadas segundo a Farmacopeia brasileira, quarta edição, nos requisitos de aspecto, pH e doseamento. Através do referido estudo, foi possível verificar que o método de espectrofotometria em UV não é recomendado para estudos de estabilidade térmica de solução de paracetamol, por sofrer interferência de seu produto de degradação.

The Interval Constructor on classes of ML-algebras

Monoidal logic, ML for short, which formalized the fuzzy logics of continuous t-norms and their residua, has arisen great interest, since it has been applied to fuzzy mathematics, artificial intelligence, and other areas. It is clear that fuzzy logics basically try to represent imperfect or fuzzy information aiming to model the natural human reasoning. On the other hand, in order to deal with imprecision in the computational representation of real numbers, the use of intervals have been proposed, as it can guarantee that the results of numerical computation are in a bounded interval, controlling, in this way, the numerical errors produced by successive roundings. There are several ways to connect both areas; the most usual one is to consider interval membership degrees. The algebraic counterpart of ML is ML-algebra, an interesting structure due to the fact that by adding some properties it is possible to reach different classes of residuated lattices. We propose to apply an interval constructor to ML-algebras and some of their subclasses, to verify some properties within these algebras, in addition to the analysis of the algebraic aspects of them

Soroprevalência de testes rápidos (ML Flow) em casos de hanseníase e contatos intradomiciliares em municípios endêmicos do Pará

A hanseníase, doença milenar, ainda constitui um grande desafio para a saúde pública, inclusive no que se refere a diagnóstico precoce e vigilância em saúde. Com objetivo de estimar a soroprevalência de anticorpos antiPGL-1 através do teste rápido ML-Flow em casos de hanseníase e seus contatos intradomiciliares de municípios endêmicos do Pará, realizou-se um estudo transversal incluindo 73 casos novos de hanseníase e 135 contatos intradomiciliares, selecionados no período de abril de 2011 a janeiro de 2012, nas unidades de referência para tratamento de hanseníase nos municípios de Belém, Marituba, Igarapé-Açú e Santarém. Os resultados demonstraram uma prevalência de 14,8/10.000hab de casos de hanseníase entre os contatos examinados. A soropositividade do ML Flow nos casos índices foi de 53,42% em pacientes multibacilares e 13,33% nos contatos intradomiciliares. Houve associação direta de positividade do ML Flow nos contatos intradomiciliares com o índice baciloscópico do caso índice. Não houve associação direta do tempo de convivência e a consanguineidade do caso índice em relação ao teste ML Flow. Houve associação entre a positividade do teste ML Flow e a realização da vacina BCG entre os contatos. Estes resultados indicam que a introdução do teste ML Flow poderia servir como instrumento auxiliar no monitoramento dos casos e seus contatos, tornando-se de grande relevância na vigilância epidemiológica da hanseníase.

Estudio histológico del processo de reparación alveolar después de la aplicación tópica de la solucioón anestésica prilocaína 3 % con felipressina o,o3 ui/ml

The aim of this study was to evaluate the local anesthetic solution, composed by Prilocaine 3% and felipressin 0,03 UI/ml, influence on the alveolar repair process in rats after dental extraction. This research was previously approved by the Ethic Committee in Research of the Masters Degree Program in Oral and Maxillofacial Surgery of the Marília University (UNIMAR), Marília, São Paulo, Brazil. It was an experimental, randomly controlled study, with bifactorial analysis (group control versus experimental group, in function of the postoperative times (2 X 4)). For the accomplishment of this study 32 rats were used (Rattus norvegicus, albinus, Wistar), males, adults, weighing between 280 and 320 grams. The animals were selected and divided into Group I (control) and Group II (Citocain 3%® - Prilocaine 3% with felipressin 0,03UI/ml) with 16 rats each; being four animals of the Group I and four of the Group II, destined to the euthanasia in the postoperative periods of 3rd, 7th, 15th and 24th days. The histological analysis with base in the developed methodology, allowed us to conclude that the anesthetic solution of Citocain 3%® applied with gauze compress on the surgical dental wound, produced tissue events that committed the basic biological principles, that are responsible for the regeneration of the gingival epithelium and the alveolar process repair in rats. The Group I presented better results in the alveolar repair when compared to the Group II.

Nebulized 0.5, 2.5 and 5 ml L-epinephrine for post-extubation stridor in children: a prospective, randomized, double-blind clinical trial

Nebulized l-epinephrine has been recommended for the treatment of viral croup. However, the few studies assessing its effect on post-extubation stridor (PES) have shown conflicting results. We compared the efficacy and safety of nebulized l-epinephrine at three different doses for the treatment of PES. We conducted a prospective, randomized, double-blind trial including all consecutive children with a PES score of a parts per thousand yen4 (Westley score). The primary efficacy outcome was change in PES score at 40 min. A reduction of a parts per thousand yen2 points in stridor score was defined as clinically significant. A total of 96 patients were randomly assigned to receive one of three doses of nebulized l-epinephrine upon achieving a PES score of 4 or more following extubation. Stridor score and vital signs were recorded before treatment, and at 20, 40, 60 and 180 min after nebulization. Baseline characteristics were similar among all study groups. No significant difference was detected among the treatments based on change in Westley score by intent-to-treat analysis. In addition, the difference in the number of patients who clinically improved among the treatment groups was not significant (p = 0.54). Patients receiving 5 ml nebulized epinephrine had a significant increase of systolic and diastolic blood pressure at 40 and 180 min. Nebulized l-epinephrine at doses of 0.5, 2.5 and 5 ml demonstrated a lack of dose response in effect on PES and a modestly clinically significant increase in undesired side effects (heart rate and blood pressure) at higher doses.

500 ml of blood loss does not decrease non-invasive tissue oxygen saturation (StO2) as measured by near infrared spectroscopy - A hypothesis generating pilot study in healthy adult women

Background The goal when resuscitating trauma patients is to achieve adequate tissue perfusion. One parameter of tissue perfusion is tissue oxygen saturation (StO2), as measured by near infrared spectroscopy. Using a commercially available device, we investigated whether clinically relevant blood loss of 500 ml in healthy volunteers can be detected by changes in StO2 after a standardized ischemic event. Methods We performed occlusion of the brachial artery for 3 minutes in 20 healthy female blood donors before and after blood donation. StO2 and total oxygenated tissue hemoglobin (O2Hb) were measured continuously at the thenar eminence. 10 healthy volunteers were assessed in the same way, to examine whether repeated vascular occlusion without blood donation exhibits time dependent effects. Results Blood donation caused a substantial decrease in systolic blood pressure, but did not affect resting StO2 and O2Hb values. No changes were measured in the blood donor group in the reaction to the vascular occlusion test, but in the control group there was an increase in the O2Hb rate of recovery during the reperfusion phase. Conclusion StO2 measured at the thenar eminence seems to be insensitive to blood loss of 500 ml in this setting. Probably blood loss greater than this might lead to detectable changes guiding the treating physician. The exact cut off for detectable changes and the time effect on repeated vascular occlusion tests should be explored further. Until now no such data exist.
