Clinical features of chronic cluster headache based on the third edition of the International Classification of Headache Disorders: A prospective multicentre study.

ABSTRACT: The criterion for the remission period of chronic cluster headache (CCH) was recently revised from < 1 month to < 3 months in the third edition of the International Classification of Headache Disorders (ICHD-3). However, information on the clinical features of CCH based on the ICHD-3 criteria is currently limited. The present study aimed to investigate the clinical features of CCH based on ICHD-3 using data from the Korean Cluster Headache Registry (KCHR). The KCHR is a multicentre prospective registry of patients with cluster headache (CH) from 15 hospitals. Among the 250 participants with CH, 12 and 176 participants were classified as having CCH and episodic cluster headache (ECH), respectively. Among 12 participants with CCH, 6 (50%) had remission periods of < 1 month, and the remaining 6 (50%) had a remission period of 1-3 months. Six participants had CCH from the time of onset of CH, and in the other 6 participants, CCH evolved from ECH. CCH subjects had later age of onset of CH, developed the condition after a longer interval after CH onset, and had more migraine and less nasal congestion and/or rhinorrhoea than ECH subjects. Clinical features of CCH with remission periods < 1 month were not significantly different from those of CCH with remission periods of 1-3 months, except for the total number of bouts. More current smoking and less diurnal rhythmicity were observed in participants with CCH evolved from ECH compared to those with ECH. In conclusion, the number of subjects with CCH doubled when the revised ICHD-3 criteria were used. Most of clinical characteristics of CCH did not differ when the previous and current version of ICHD was applied and compared. Some clinical features of CCH were different from those of ECH, and smoking may have a role in CH chronification.

Project description:OBJECTIVE:To prospectively assess the construct and criterion validity of ClassIntra version 1.0, a newly developed classification for assessing intraoperative adverse events. DESIGN:International, multicentre cohort study. SETTING:18 secondary and tertiary centres from 12 countries in Europe, Oceania, and North America. PARTICIPANTS:The cohort study included a representative sample of 2520 patients in hospital having any type of surgery, followed up until discharge. A follow-up to assess mortality at 30 days was performed in 2372 patients (94%). A survey was sent to a representative sample of 163 surgeons and anaesthetists from participating centres. MAIN OUTCOME MEASURES:Intraoperative complications were assessed according to ClassIntra. Postoperative complications were assessed daily until discharge from hospital with the Clavien-Dindo classification. The primary endpoint was construct validity by investigating the risk adjusted association between the most severe intraoperative and postoperative complications, measured in a multivariable hierarchical proportional odds model. For criterion validity, inter-rater reliability was evaluated in a survey of 10 fictitious case scenarios describing intraoperative complications. RESULTS:Of 2520 patients enrolled, 610 (24%) experienced at least one intraoperative adverse event and 838 (33%) at least one postoperative complication. Multivariable analysis showed a gradual increase in risk for a more severe postoperative complication with increasing grade of ClassIntra: ClassIntra grade I versus grade 0, odds ratio 0.99 (95% confidence interval 0.69 to 1.42); grade II versus grade 0, 1.39 (0.97 to 2.00); grade III versus grade 0, 2.62 (1.31 to 5.26); and grade IV versus grade 0, 3.81 (1.19 to 12.2). ClassIntra showed high criterion validity with an intraclass correlation coefficient of 0.76 (95% confidence interval 0.59 to 0.91) in the survey (response rate 83%). CONCLUSIONS:ClassIntra is the first prospectively validated classification for assessing intraoperative adverse events in a standardised way, linking them to postoperative complications with the well established Clavien-Dindo classification. ClassIntra can be incorporated into routine practice in perioperative surgical safety checklists, or used as a monitoring and outcome reporting tool for different surgical disciplines. Future studies should investigate whether the tool is useful to stratify patients to the appropriate postoperative care, to enhance the quality of surgical interventions, and to improve long term outcomes of surgical patients.

Project description:ObjectiveTo determine the pain intensity of cluster headache through a large survey by comparing it to other painful disorders. Furthermore, to investigate the relationship between maximal pain, autonomic, and other clinical symptoms, as well as demographic attributes of cluster headache.BackgroundThe pain of cluster headache is anecdotally considered to be one of the worst pains in existence. The link between pain and autonomic features of cluster headache is understood mechanistically through the trigeminovascular reflex, though it is not clear if this is a graded response. Links between pain and other features of cluster headache are less well understood.MethodsThis Internet-based cross-sectional survey included questions on cluster headache diagnostic criteria, which were used as part of the inclusion/exclusion criteria for the study. Respondents were asked to rate a cluster headache attack on the 0-10 numerical rating scale. Additionally, they were asked if they had experienced a list of other painful conditions such as labor pain or nephrolithiasis; if so they were asked to rate that pain as well. The survey also included demographics, mood scores, and treatment responses.ResultsA total of 1604 cluster headache respondents were included in the analysis. Respondents rated cluster headache as significantly (p < 0.001) more intense than every other pain condition examined. Cluster headache attacks were rated as 9.7 ± 0.6 (mean ± standard deviation) on the numerical rating scale, followed by labor pain (7.2 ± 2.0), pancreatitis (7.0 ± 1.5), and nephrolithiasis (6.9 ± 1.9). The majority of cluster headache respondents rated a cluster headache attack at maximal or 10.0 pain (72.1%, 1157/1604). Respondents with maximal pain were statistically significantly more likely to have cranial autonomic features compared to respondents with less pain: conjunctival injection or lacrimation 91% (1057/1157) versus 85% (381/447), eyelid edema 77% (887/1157) versus 66% (293/447), forehead/facial sweating 60% (693/1157) versus 49% (217/447), fullness in the ear 47% (541/1157) versus 35% (155/447), and miosis/ptosis 85% (1124/1157) versus 75% (426/447) (all p values <0.001). Respondents with maximal pain also had other statistically significant findings: more frequent attacks (4.0 ± 2.0 attacks per day vs. 3.5 ± 2.0 attacks per day), higher Hopelessness Depression Symptom Questionnaire scores (24.5 ± 16.9 vs. 21.1 ± 15.2), decreased overall effectiveness from calcium channel blockers (on a 5-point Likert scale), and more likely female: 34% (389/1157) versus 24% (108/447) (all p values <0.001). Pain intensity was not associated with restlessness, headache duration, age of onset, episodic/chronic status, or the effectiveness of any acute or preventive medication other than calcium channel blockers.ConclusionsCluster headache is an intensely painful disorder, even in the context of other disorders considered intensely painful. Maximal pain intensity is associated with more cranial autonomic features, suggesting a graded response between pain and autonomic features. Maximal pain intensity is also associated with headache frequency but not duration, suggesting a relationship between pain intensity and mechanisms controlling headache onset, but not between pain intensity and mechanisms controlling headache offset.
