Although studies reviewed thus far support the efficacy of lithium treatment for acute mania, the presence of concurrent depression or depressive symptoms during mania, the so-called mixed state, has been associated with poor lithium response. In 1976, Himmelhoch et al. observed that patients with mixed states were significantly less likely to demonstrate a good treatment response than were manic patients [42% vs. 81%] in a retrospective chart review of 84 consecutively referred patients with bipolar disorder. Secunda et al. [1985] reported on 18 patients with mania studied as part of the Collaborative Study of the Psychobiology of Depression and found that patients with concomitant depression and mania [n = 8] had a significantly lower rate of...

In a collaborative study of the French Pharmacovigilance Centers there were 23 reports of suspected reactions to pyritinol, including four cases of pemphigus, three of agranulocytosis (but other drugs taken were oxyphenbutazone or clomipramine), two of nephrosis, and two of a lupus-like syndrome (6). 

Other collaborative studies of the commercially available kits have been reported. For example Mortimer and co-workers (16) recently reported on the use of the Quantitox B, ELISA kit produced by May and Baker Diagnostics, Glasgow In analysis of peanut butter. Their conclusion was that the kit can be used effectively to indicate aflatoxin B, levels in peanut butter, preferably using a peanut butter zero reference.

Exposure levels of a product should be confirmed by monitoring that uses calibrated radiometers or lux meters. Validated chemical actinometry can also be used for this purpose. For near-UV light, quinine actinometry is noted in the appendix of the guideline. Quinine actinometry was adopted because its usefulness was confirmed by a collaborative study of the ICH working group892 and by a study carried out by the U.S. Food and Drug Administration.893 However, concern has been expressed about the usefulness of quinine acti-...
