Abstract：
UNASSIGNED: Early diagnosis of CH is a cornerstone and it is important to detect causes leading to diagnostic delay. Limited published data exist regarding CH in Egypt, and with no data showing characteristics of CH or causes of diagnostic delay .
UNASSIGNED: To investigate clinical characteristics, for CH and detect causes of diagnostic delay in Egypt.
UNASSIGNED: A cross-sectional study was conducted including all patients (age: 18-60 years) with primary headache disorders in Egypt with CH patients consecutively recruited over 1 year. Demographic and clinical characteristics as well as rate of diagnostic delay were collected.
UNASSIGNED: This registry included 1187 patients with primary headaches over a year. CH accounted for 1.9% . The majority of CH patients were males (82%), and a mean age of 37.9 ± 10 years. The mean age of disease onset was 25 ± 8 years. Sixty-five percent had episodic CH, while 34.8% had chronic CH. Most of the patients (95.7%) had strictly unilateral pain (right side 52.2%, left side 43.5%). Autonomic features were rhinorrhea (91%), ptosis (87%), and lacrimation (78%). Migrainous features were found in 26% of patients. Bout duration of CH lasted on an average of 1-4 months. Time interval of diagnostic delay ranged from 0.5 to 29 years, with a mean diagnostic delay of 9.8 ± 7.9 years.
UNASSIGNED: This study showed that CHs present 1.9% of primary headache disorders in Egypt, with males more affected than females. the incidence of smoking was higher among CH patients. Marked diagnostic delay was found which necessitate an action toward raising awareness.

摘要：
■CH的早期诊断是基石，检测导致诊断延迟的原因很重要。关于埃及CH的公开数据有限，并且没有数据显示CH的特征或诊断延迟的原因。
■为了研究临床特征，并检测埃及诊断延迟的原因。
■进行了一项横断面研究，纳入了埃及原发性头痛障碍的所有患者（年龄：18-60岁），并连续招募了1年以上的CH患者。收集人口统计学和临床特征以及诊断延迟率。
■该注册表包括一年以上的1187名原发性头痛患者。CH占1.9%。大多数的CH患者是男性（82%），平均年龄为37.9±10岁。发病的平均年龄为25±8岁。65%的人有阵发性CH，34.8%患有慢性CH。大多数患者（95.7%）有严格的单侧疼痛（右侧52.2%，左侧43.5%）。自主神经特征为鼻漏（91%），上睑下垂（87%），和流泪（78%）。在26％的患者中发现了偏头痛特征。CH的发作持续时间平均为1-4个月。诊断延迟的时间间隔为0.5至29年，平均诊断延迟9.8±7.9年。
■这项研究表明，在埃及，CHs占原发性头痛疾病的1.9％，男性比女性受影响更大。CH患者的吸烟率较高.发现明显的诊断延迟，需要采取行动提高认识。
