Over a two year period 108 patients had cranial computerised tomographic (CCT) scans while under the care of a general medical team. Sixty eight scans showed 70 abnormalities. Completed stroke, transient ischaemic attacks (TIA), epilepsy and headache were the most common indications for CTT while infarct, atrophy, haemorrhage and tumour were the most common abnormalities. Eight tumours were identified comprising 12% of epileptics and 9% of stroke patients.

Chronic daily headache (CDH) is one of the more frequently observed headache syndromes at major tertiary care centers. CDH is defined as headache occurring >15 days/month. Different mechanisms are involved in the development of CDH but what factors specifically contributing to the transformation from episodic into CDH remain largely unknown. Analgesic overuse is commonly identified as the most important factor for such transformation. Hypertension, allergy, asthma, arthritis, diabetes, obesity and hypothyroidism were associated with CDH in clinical series. The objective of this study is to identify risk factors of chronicity in patients with headache. A total of 1,483 consecutive patients were studied. We collected information on age, gender, headache type and comorbidity. Patients were divided into three diagnostic groups: migraine and tension-type headache (CTT) diagnosis were made according to ICHD-II, and CDH fulfilling the Proposal Headache Classification for Chronic Daily Headache described by Silberstein and Lipton (in Chronic daily headache including transformed migraine, chronic tension-type headache, and medication overuse, 2001). We used descriptive statistics and Chi-square test. Our data show that age, gender and headache onset were similar in the three groups. Diabetes, hypercolesterolaemia, smoke and cardiopathy prevalence did not differ in the three groups (P > 0.05). Hypertension prevalence in CDH group (16.2%) was significantly higher than in the other two groups (migraine 7.3%; CTT 6.6%; P < 0.01). There were no differences (P > 0.05) in hypertension prevalence between CDH with and without medication overuse. CDH patients (mean age 41.8 +/- 14) referred to the Headache Center later than migraine and CTT patients (mean age 37 +/- 12) (P > 0.05). According to previous studies we found that hypertension is more frequent in CDH than in migraine and CTT. Examining this result it is possible to conclude that there exists an association between CDH and hypertension, but not that a causal relationship necessarily exists. Considering the other somatic conditions we did not find any correlation. The potential role of somatic comorbidity in CDH has to be studied in further clinical trials.
