| Circular headache (Nummular headache, NH) is a special type ofheadache, refers to the distribution at the scalp surface2~6cm diametercircular or elliptic limitation headache, which is about the size of the coin,also known as coin headache, on the right side of the head for thecommon headache part of the disease. In2002by the Spanish scientistsParejaJ.A.in13patients with clinical manifestations of different headacheto study and put forward, when similar cases have been more than100cases. In2004, by the international headache society committee in theinternational headache classification criteria for the diagnosis of appendixheadacheⅡ(ICHD-ⅡA13.7.1) made the diagnosis standard of NH. Thedisease onset age much fluctuation in the13~72, an average of40yearsold, give priority to with young women, the literature reported youngestpatient of NH4years old, and the largest for the72year old, duration is1~50years more. Confirmed NH is mainly based on the clinicalmanifestations of patients. As there is no incentive in NH, no accompanysymptoms, pain "back pain", to outline a clear the scope of the area isfixed, speculated that its pathogenesis is peripheral nerve conductiondysfunction, but the disease incidence is low, there is no large~scaleepidemiological studies, mostly small sample or case reports, so this kindof viewpoint is not fully confirmed.2004years later, through thegradually deepening understanding of the NH, research found that many clinical manifestations of relatively special circular headache, such asmenstrual NH, immune dysfunction related to NH, two point ormultipoint NH, intracranial tissue lesions caused by NH, etc., thesespecial NH that scholars have the update on the pathogenesis of NH,think if NH is other early clinical manifestation of primary disease, butthere is no sufficient evidence to support this perspective. UntilDecember2012, the various parts of the world reported298cases of NH,32cases in China, the literature shows that NH treatment methods varied,including commonly used painkiller oral, topical application of botulinumtoxin A, local nerve block, electrical stimulation, etc. Through the studyfound that patients with mild NH used drugs can play A good effect ofprevention and treatment, and patients with moderately severe NH forbotulinum toxin A curative effect is distinct, efficiency above80%, andaccepted by most scholars. But in general, because the disease has certainself~healing, all kinds of treatment are not must measure. More easilybecause of the special clinical manifestations of the disease, headache,trigeminal neuralgia, and migraine headaches or other type identification.This time, we altogether collected confirmed within three years in5patients diagnosed patients with NH, based on the research of the fivepatients with NH, confirmed that the early onset of the disease drugtreatment effect is good, and5patients with NH is occurs in women,mainly on the right side of the head of this clinical characteristics consistent with reported in the literature, due to the low prevalence of thedisease, the pathogenesis of research is more difficult, in the futurelearning, should actively collected clinical data, enlarge the sample size, alonger follow up period, to prepare for the pathogenesis of NH indepthexploration. |
