After some brief remarks on the pathogenesis of vasomotor cephalea, the properties of the antiaminic drug BC 105 (Sandomigran) are described and the results reported of using it in 171 patients suffering from cephalea of three types: vasomotor cephalea in 50 cases, vasomotor cephalea with associated neurosic component in 26 cases, and post-traumatic cephalea in 95 cases. In the first two types, the positive results obtained confirm the usefulness of BC 105 in basic treatment of vasomotor cephalea. In post-traumatic cephalea which is a notoriously difficult therapeutic problem, the results obtained, although only partially positive, are worthy of the fullest consideration.

The purpose of this study was to evaluate the prevalence of life-threatening renal failure (RF) caused by vasomotor nephropathy associated with nonsteroidal anti-inflammatory drug (NSAID) treatment (NSAID-RF) and risk factors for this renal impairment in an inception cohort of patients with recently diagnosed uremia treated by emergency hemodialysis in a prospective regional study. There are few published data on this phenomenon. Two hundred fifty-six patients (137 men, 119 women, mean age 68 years [22-95 years]) with acute uremia were treated with emergency hemodialysis in the intensive care unit over a period of 70 months. The patients were from an area of 231,000 inhabitants. Of the 256 patients, clinical data from a group of 79 patients with medical-type renal failure were analyzed in detail. The prevalence of NSAID-RF was 8%. This prevalence decreased to 4% when patients without any other medication affecting compensatory renal hemodynamics were considered. Moreover when nonpharmacological insults were not taken into account the prevalence decreased to only 1.6%. In 80% of the patients with NSAID-RF, nonpharmacological insults contributed to renal impairment. Both hypotension of cardiac etiology and dehydration/hypovolemia were present in 25% of the patients with this type of RF while urinary tract obstruction was seen in 1%. In 75% patients with NSAID-RF the underlying nephropathies were identified. NSAID-RF was not frequent. The population at greatest risk for renal functional alteration associated with NSAID therapy included patients with dehydration/hypovolemia, hypotension of cardiac etiology and those with pre-existing renal impairment, especially with vascular and analgesic nephropathy.
A double-blind crossover trial of clonidine failed to show any effect of the drug on menopausal vasomotor symptoms. A significant placebo effect was observed, the effect being greater in those with long-standing symptoms and a high neurotic index.
