” ” Artificial food colourings and additives (AFCAs) have long been suggested to adversely affect the learning and behaviour in children. In this study, we aimed to provide additional data to clarify the possible side effects of colouring additives on behaviour and memory. We administered acceptable daily intake values of AFCAs as a mixture (Eritrosin, Ponceau 4R, Allura Red AC, Sunset Yellow FCF, Tartrazin, Amaranth, Brilliant Blue, Azorubin and Indigotin) to female rats before and during gestation and then tested their effects on behaviour and on spatial working memory in their offspring. … Our results showed that commonly used artificial food colourings have no adverse effects on spatial working memory and did not create a depressive behaviour in offspring. But they showed a few significant effects on locomotor activity as AFCAs increased some parameters of locomotor activity . “ MedLine
Metyrapone is used for the medical control of hypercortisolism in Cushing's syndrome (ACTH dependent or independent). The aim for medical treatment is to achieve pre-operative control of hypercortisolism, or for control of residual disease persisting post-operatively (TSS, adrenalectomy). It is not for long term definitive treatment/cure, only as an adjunct (surgery is the aim for cure in most causes of Cushing's syndrome). Metyrapone hence acts by inhibiting adrenal steroidogenesis. One side effect is hirsutism (in women) because of the excess androgen precursors created. The other commonly used agent for medical treatment of Cushing's is ketoconazole (an anti-fungal agent). This does not exhibit the side effect of hirsutism.
Although patients receiving systemic corticosteroid therapy are more susceptible to secondary infection than patients not receiving corticosteroids, administration via the inhaled route minimizes this risk. Corticosteroid therapy can mask the symptoms of infection and should not be used in cases of bacterial, fungal, or viral infections that are not adequately controlled by anti-infective agents, except in life-threatening circumstances. Fluticasone; salmeterol should be avoided in patients with tuberculosis infections of the respiratory tract if possible. The incidence or course of acute bacterial or viral infection is probably minimally affected by inhaled corticosteroids in immunocompetent individuals; however, close monitoring of patients with immunosuppression is recommended if treatment with an inhaled corticosteroid is necessary.
