In these two patients, as in 13 others described in the literature, a typical meningitic syndrome with excitement, confusion and a fever of 104degrees F (40degrees C) appeared 4-6 hours following the intra-thecal injection. Subsequent lumbar puncture usually reveals a cloudy C.S.F. under increased pressure. The polymorphs and proteins are increased but the glucose remains normal. There are no bacteria either on direct examination or after culture. All the patients receive antibiotics. After a course of three days, the symptoms and the fever have disappeared and the C.S.F. became normal. Bacterial contamination can be ruled out. The relative roles of iodine, radio-acitivity itself, albumine and of the radio-active element which are only used for this radiotracer are discussed. The tracer contains neither stabilizer nor pH buffer. One must presume that the syndrome is due to a direct toxic action rather than to an immunological or allergic reaction. Furthermore, it is of interest that similar reactions, without infection, are seen after spinal anaesthesia and intra-thecal injection of such differing substances such as iodine contrast media, gamma globulins, other isotopes or toxic substances (Lysol) (111In-DTPA).

We report the cases of two adults suffering from acute hepatitis due to cyclofenil (Ondogyne), a drug proposed for the treatment of dysovulation and scleroderma. Hepatitis developed 30 and 102 days after the beginning of discontinuous administration of the drug. A challenge test was positive in both cases. The course of hepatitis was reversible after withdrawal of the drug. Hepatitis induced by cyclofenil is likely to be due to an hypersensitivity mechanism.
