Our objective was to establish the proportion of Emergency Room and Intensive Care doctors and nurses able to locate the carotid pulse in less than 5 s, and identify the variables that influence this ability. The method followed was locating the carotid pulse in a healthy male adult volunteer with normal blood pressure in two situations (stretcher or floor) and with the neck in either a neutral or in an extended position. We recorded the gender, age, and previous training in cardiopulmonary resuscitation (CPR) of each participant and the time spent in detecting the pulse in each of the four possible positions. A model of logistic regression was constructed to determine if the patient's position had any influence on the proportion of health workers capable of finding the pulse within 5 s. The average age of the 72 subjects studied was 33.4 years (SD = 6.6); 80% of the participants had CPR training. Thirty-one participants (43.1%; CI 95%, 31.4-55.3%) required more than 5 s to detect the pulse, although only three (4.2%; CI 95%, 0.9-11.7%) required more than 10 s. The variable 'no CPR training' was associated with the inability to detect the pulse within 5 s. The detection of the pulse was easier with an extended neck. A significant proportion of nurses and doctors were slow to locate the carotid pulse on a healthy, young volunteer with normal blood pressure. No relation was found between gender or age of the participants. More attention should be given to carotid pulse detection in CPR training.

Sarcoidosis is a disease which presents important clinical differences according to its geographical distribution. Thus, the objective of this study was to evaluate the epidemiologic, clinical, radiologic, and diagnostic characteristics in a series of 30 sarcoidosis patients in the province of Salamanca (representing the Castilla-Leon region). The most relevant results are the following: a) in our region, sarcoidosis predominates in females and furthermore, the presenting age in females is greater than in males; b) there is a clear predominance of the disease in the rural area; c) the prevalence of smoking habit in these patients is low (10%); d) the clinical manifestations are similar to other Spanish series with the exception, however of a high incidence of hypercalciuria; e) there is no correlation between the increase in sedimentation rate and the degree of sarcoidosis activity; f) there is a predominance of the radiologic type 11 of the disease and there is a high number of atypic radiologic patterns. The results obtained are with regard to the pathogeny are discussed as well as the differences and similarities of this series with other preceding from other regions.
