In the present report, the physicochemical quality evaluation of three batches of lactose monohydrate as raw material of a national pharmaceutical laboratory was carried out through physicochemical parameters such as description of the sample, solubility and identification by infrared spectrophotometry (IR) , and specific tests such as the determination of water by Karl Fischer, transparency and color of the solution, optical rotation, acidity or alkalinity, loss on drying, residues of incineration and proteins and impurities that absorb light; which were based on the analytical technique of the laboratory, taking as reference the United States Pharmacopeia (USP 40). The physicochemical parameters comply with the specifications established in the analysis protocol of the quality control department for lactose monohydrate as a raw material

This report presents the results obtained from the determination of the risk of rheumatoid arthritis through modifiable and non-modifiable factors in adult inhabitants of both sexes of the Buenos Aires sector of the Víctor Larco Herrera district. Among the modifiable factors were taken into account the body mass index (BMI), physical activity, tobacco and alcohol consumption; and non-modifiable factors such as sex, age and rheumatoid factor. The determination of the rheumatoid factor was performed with the Latex Agglutination - Polystyrene method. 40% of the samples processed were positive cases of rheumatoid factor and 60% negative cases. Regarding sex, 6% were positive cases of rheumatoid factor belonging to the male sex and 34% to the female sex. On the other hand, the distribution by age range is shown, observing a higher percentage of positive cases (12%) between 66 and 75 years. A...
