[Prospective epidemiologic study of headache in ambulatory neurology service in the province of Palencia].

OBJECTIVES: To study demographic data about the first time consultations for headache in our neurologic clinic, its diagnostic distribution, its diagnostic and therapeutic management by the neurologist, its source, and the influence of the primary care doctors formation in their search of neurological consultation and therapeutic management in patients with headache. PATIENTS AND METHODS: A protocol with several demographic clinical and medical care data of the all first time visits for headache in our province was picked up, during 3 consecutive months. RESULTS: Headaches represent 21.5% of the first time consultations. The majority of the patients were women. The primary care doctors sent 93.6% of patients. The two more common diagnoses were tension-type headache (60%) and migraine (25.4%), reflecting their prevalences in the population. The more common treatments were the associations of two drugs. The general doctors sent more patients with headache (3.36 per thousand and year) than family doctors (1.84 per thousand and year). The approximation between initial diagnosis (primary care doctor) and final diagnosis (neurologist) was 26.4%, greater for family doctors (38.1%) than for general doctors (23.9%). CONCLUSIONS: Headaches represent the first cause of neurological consultation. The diagnostic distribution of the patients sent to our province shows the prevalences in the population. The family medicine formation is useful for a better selection of the patients sent to neurologists and a better diagnostic approach.

[Semiquantitative evaluation of cranial computerized tomography as diagnostic support in progressive supranuclear palsy].

INTRODUCTION AND OBJECTIVES: Different neuroimaging findings have been described in association with progressive supranuclear palsy (PSP), but their use as diagnostic support in this condition has been the subject of much discussion. PATIENTS AND METHODS: Three radiologists, non-specialists in neuroradiology and with no specific information regarding neuroimaging in Parkinson syndromes, analyzed (without knowing any clinical details) seven cranial CT in five patients diagnosed as probable PSP according to NINDS-SPSS criteria, nine with idiopathic Parkinson's disease, and six persons aged over 55 years who acted as controls. The radiologists were asked to assess 17 variables as absent, moderate or severe. The results were analyzed using the chi squared test for qualitative variables and Fisher's exact test when necessary. RESULTS: The identification of the variables antero-posterior and transversal atrophy of the mid-brain, atrophy of the pons, enlargement of the perimesencephalic cisterns and the quadrigeminal plate and increased size of the third ventricle were considered to be statistically significant in the cases of PSP as compared with other observations. The small number of patients did not permit the establishment of correlation of statistical importance between the radiological parameters and clinical condition. CONCLUSIONS: We present the point of view of non-specialist neuroimaging workers, in these patients. We found that there were six parameters of interest on cranial CT which permitted differentiation of cases of PSP, idiopathic Parkinson's disease and a control population. Four of these parameters did not appear to a severe degree in patients who did not have PSP. These results are partly comparable to those published in the literature.
