Intranasal corticosteroids (INCs) act predominantly locally and are considered to exert minimal systemic effects. On reviewing the international data collected in the World Health Organization's global pharmacovigilance programme an unexpected cluster was found of 38 case reports of migraine in suspected connection with INCs. These reports came from five countries (May 2007) and concerned six different drugs. In all reports the INC was the sole suspect drug. In nine cases re-exposure to the drug had taken place, leading to the recurrence of the event in eight of these patients. However, INCs are mainly used for rhinitis, and there is a known connection between rhinitis and migraine. Although representing only 0.6% of the total of case reports, international pharmacovigilance data suggest that the use of INCs may cause or trigger migraine or migraine-like headache. Further study is needed to determine if the reported association is true or not and, if so, what the possible mechanism is. [ABSTRACT FROM AUTHOR]

Congestive heart failure in the elderly which might be due to treatment with nonsteroidal anti-inflammatory drugs was studied by means of a questionnaire sent to the participants of a postgraduate course on locomotor disease in the elderly, and also by analysis of the hospital records of 600 elderly subjects diagnosed with congestive heart failure. The questionnaire revealed 22 possible cases, reported by 20 physicians (84 physicians out of 243 responded). In the hospital population five probable cases were detected. Details of these patients are presented. In contrast with findings in the literature, solute retention was in no case the result of kidney function impairment. The specific problems regarding the attribution of this adverse effect are discussed. The results of our study provide further evidence that congestive heart failure due to nonsteroidal anti-inflammatory drug treatment is a probable adverse drug reaction in elderly individuals with or without a history of impaired cardiac performance. It may result from drug toxicity following (relative) overdosing in this age group, from reduced effectiveness of concomitant diuretic treatment or from effects on cardiovascular homoeostasis.

There have been a few reports on stroke as a side-effect of antihypertensive treatment. To study the occurrence of this side-effect, a questionnaire was sent to all Dutch nursing homes (n=322). Thirty patients were reported with signs of cerebral ischaemia shortly after starting antihypertensive and diuretic drugs. Nine of these cases were well documented with full data on blood pressure, measured immediately after the event and compared with pretreatment levels. A review of cases reported in the literature is presented. It is concluded that, especially in elderly patients, an abrupt fall in blood pressure may induce cerebral ischaemia, sometimes resulting in stroke. Antihypertensive treatment in the elderly should therefore start with a small dose, the aim being to reduce blood pressure gradually. [ABSTRACT FROM PUBLISHER]
