Opiate toxicity after self poisoning with aspirin and codeine

Preparation and Evaluation of High Drug Content Particles

To determine how to prepare high drug content particles using a Wurster fluidized bed to determine realizing the miniaturization of solid dosage forms, aspirin was selected as the model drug and granulated without any additive. In this study, the emphasis was on evaluating the key operation factors of airflow rate and atomizing flow volume. The properties of the resulting particles, such as the average diameter, particle strength, appearance, and compressibility using different airflow rates and atomizing flow volumes, were investigated. Furthermore, detailed optimization of the operation conditions was conducted by artificial neural network (ANN) analysis. The relationship between the controlling factors (powder supplied, concentration of spray liquid, the amount of consumed spray liquid, and spray rate) and the response variables (product yield, median diameter, angle of repose, and degradation of aspirin) was investigated after evaluating the airflow rate and atomizing flow volume effects. The resulting granules under optimum operation conditions showed excellent physicochemical properties such as particle size uniformity, flowability, and compressibility.

Acute renal failure following Yersinia pseudotuberculosis septicaemia

Although Yersinia pseudotuberculosis has not been previously reported to cause acute renal failure, it accounted for two cases reported here out of eighty referrals with acute renal failure to our renal unit over the last year. This may suggest that the incidence of Yersinia pseudotuberculosis may be greater than that previously reported, and it should be suspected in patients presenting with bloody diarrhoea in association with renal failure. The septicaemic form of the disease is life threatening and requires intensive supportive therapy.
