Clinical analysis of benign paroxysmal vertigo of childhood with frequent episodes / 中国基层医药

Objective To discuss the clinical characteristics of benign paroxysmal vertigo of childhood (BPVC) with frequent episodes,in order to further improve the level of diagnosis and treatment.Methods The clinical data of 25 cases with frequent episodes of BPVC were analyzed retrospectively.All cases were treated with regimen for migraine.Results Aspirin combined with propranolol had the best effect,quick effect,short period of treatment and minimal side effect.Conclusion Aspirin and propranolol are commonly used drugs in the treatment of migraine,which can effectively treat frequent episodes of BPVC,and is economical and practical,and it is conducive to promotion at the grass-roots level.It also confirms the homology of children with benign paroxysmal vertigo and migraine.

Multicenter clinical study of childhood periodic syndromes that are common precursors to migraine using new criteria of the International Classification of Headache Disorders (ICHD-II) / 소아과

PURPOSE: To evaluate the clinical features and characteristics of childhood periodic syndromes (CPS) in Korea using the new criteria of the International Classification of Headache Disorders (ICHD)-II. METHODS: The study was conducted at pediatric neurology clinics of five urban tertiary-care medical centers in Korea from January 2006 to December 2007. Patients (44 consecutive children and adolescents) were divided into three groups (cyclic vomiting syndrome [CVS], abdominal migraine [AM], and benign paroxysmal vertigo of childhood [BPVC]) by recurrent paroxysmal episodes of vomiting, abdominal pain, dizziness, and/or vertigo using the ICHD-II criteria and their characteristics were compared. RESULTS: Totally, 16 boys (36.4%) and 28 girls (63.6%) were examined (aged 4-18 yr), with 20 CVS (45.5%), 8 AM (18.2%), and 16 BPVC (36.4%) patients. The mean age at symptom onset was 6.3+/-3.6 yr, 8.5+/-2.7 yr, and 8.5+/-2.9 yr in the CVS, AM, and BPVC groups, respectively, showing that symptoms appeared earliest in the CVS group. The mean age at diagnosis was 8.0+/-3.4 yr, 10.5+/-2.6 yr, and 10.1+/-3.2 yr the CVS, AM, and BPVC groups, respectively. Of the 44 patients, 17 (38.6%) had a history of recurrent headaches and 11 (25.0%) showed typical symptoms of migraine headache, with 5 CVS (25.0%), 2 AM (25.0%), and 4 BPVC (25.0%) patients. Family history of migraine was found in 9 patients (20.4%): 4 in the CVS group (20.0%), 2 in the AM group (25.0%), and 3 in the BPVC group (18.8%). CONCLUSION: The significant time lag between the age at symptom onset and final diagnosis possibly indicates poor knowledge of CPS among pediatric practitioners, especially in Korea. A high index of suspicion may be the first step toward caring for these patients. Furthermore, a population-based longitudinal study is necessary to determine the incidence and natural course of these syndromes.
