Primary stabbing @entity10 ( @entity26782 ) is a @entity158 , as brief, sharp, jabbing stabs, predominantly felt in the first division of trigeminal nerve. Population studies have shown that @entity26782 is a common @entity10 . However, most @entity1 suffer attacks of low frequency or intensity and seldom seek for medical assistance. There are few clinic-based studies of @entity26782 , and its real influence as a primary cause for referral to neurology outpatient offices is to be determined. We aim to investigate the burden of @entity26782 as main complaint in an outpatient @entity10 clinic. We reviewed all @entity1 with @entity26782 ( @entity1605 ), attended in an outpatient @entity10 clinic in a tertiary hospital during a 2.5-year period (January 2008-June 2010). We considered demographic and nosological characteristics and if @entity26782 was main cause of submission. 36 @entity1 (26 females, 10 males) out of 725 (5%) were diagnosed of @entity26782 . Mean age at onset 34.1      2.9  years (range 10-72). Mean time from onset to diagnosis 68.8      18.3  months. Twenty-four @entity1 fulfilled @entity1605 for other @entity10 (14 @entity2704 , 6 @entity2701 , 2 hemicrania continua, 1 primary @entity12967 and 1 primary exertional @entity10 ). 77.7% of @entity1 were submitted from primary care. In 14 @entity1 (39%), @entity26782 was main reason for submission, its intensity or frequency in 5 (35.7%) and fear of malignancy in 9 (74.3%). Only two @entity1 of those who associated other @entity10 were submitted due to @entity26782 . In conclusion, @entity26782 is not an uncommon diagnosis in an outpatient @entity10 office. However, and according to our data, it is not usually the main cause of submission to a @entity10 clinic.
