Changes in diagnostic criteria, for example, the various International Classification of Headache Disorders criteria, would lead to changes in the outcomes of epidemiological studies. International Classification of Headache Disorders-1 was based mainly on expert opinion, yet most of the diagnostic criteria were reliable and valid, but it did not include chronic migraine. In its second version, the classification introduced chronic migraine, but this diagnosis resembled more a high-frequency migraine rather than the actual migraine transformation process. It also introduced medication overuse headache, but it necessitated analgesic withdrawal and subsequent headache improvement to be diagnosed as such. Hence patients having medication overuse headache could only be diagnosed in retrospect, which was an awkward situation. Such restrictive criteria for chronic migraine and medication overuse headache omitted a high proportion of patients. International Classification of Headache Disorders-3 allows a diagnosis of medication overuse headache due to combination analgesics if taken for at least 10 days per month for more than three months. Hence the prevalence rate of medication overuse headache and chronic migraine can increase compared to the previous version of the headache classification. Different criteria have been used across studies to identify chronic migraine and medication overuse headache, and therefore the information acquired from previous studies using earlier criteria becomes uncertain. Hence much epidemiological research would need to be interpreted cautiously or repeated with the most updated criteria, since the subjects in studies that apply the latest criteria may be phenotypically different from those in older studies.

Headache is a common disease of the general population. But the main problem in any study of headache has been that of defining the disease entities. In 1988, the Headache Classification committee of the International Headache Society introduced operational diagnostic criteria for all headache disorders into 13 major group; migraine, tension-type headache, cluster headache and chronic paroxysmal hemicrania etc. Sjaastad was the first to describe "cervicogenic headache", one of various head pain syndromes that probably originate in the cervical spine. Between March 1995 and June 1995, we studied 78 out-patients of the Department of Neuro pain clinic, Sanggye Paik Hospital, Inje university. We divided the patients into three study group: Fifty-three patients with tension-type headache, 13 with cervicogenic headache, and 12 with migraine headache. The reponse of trigger point injection and $C_2$-ganglion block in patients was investigated. We paid particular attention to the response of trigger point injection in patients of the three group. The effect of trigger point injection was more marked in tension-type headache group than in the other categories. The pain reduction after $C_2$-ganglion block was more marked in cervicogenic headache group than in the others.

목 적 : 소아에서 비교적 흔한 것으로 알려진 편두통은 성인과 다른 양상을 보이므로 성인의 편두통 진단기준을 그대로 이용하기가 곤란하다. 최근 국제두통학회에서 발표한 새로운 진단기준에 근거하여 전조를 동반하지 않는 편두통 환자의 임상적 특징과 이전의 진단기준 적용시와의 차이점에 대해 알아보고자 하였다. 방 법 : 2003년 9월부터 2004년 7월까지 강북삼성병원 소아과 외래에 두통을 주소로 내원하였던 102명의 환자 중에서 국제두통학회의 개정된 기준에 근거하여 진단 내린 전조를 동반하지 않는 편두통 환자 27명과 진단기준 4가지 중 1가지를 만족시키지 못하는 개연적 편두통 환자 7명을 대상으로 임상적 특징을 분석하고 이전의 편두통 진단기준과 비교분석하였다. 결 과 : 전조를 동반하지 않는 편두통 환자는 27명(26.5%)이었으며 평균 연령은 11.0세, 남녀비는 1.7 : 1이었으며 10명(37.0%)에서 편두통의 가족력이 있었다. 편두통의 기간은 평균 16.3개월이었고 빈도는 한달에 평균 13.1회였으며, 지속시간은 2시간 이상이 12례(44.4%)였고 1-2시간이 15례(55.6%)를 차지하였다. 발생부위는 전두부가 9례, 후두부가 2례, 측두부가 14례였으며, 측두부일 경우 편측성이 11례, 양측성이 3례였고, 양상은 압박성(15례, 55.6%)이 편두통의 전형적인 양상인 박동성(6례, 22.2%)보다 많았다. 개연적 편두통 환자는 7명(6.8%)이었으며, 지속시간이 1시간 미만인 경우가 5명인 것을 제외하고는 그 외의 특징에서 편두통 환자와 비슷한 양상을 보였다. 이전 진단 기준을 동일한 환자들에게 적용했을 때 전조를 동반하지 않는 편두통 환자는 9명(8.8%)으로 개정된 진단기준에서의 27명(26.5%)과 큰 차이를 보였다. 결 론 : 소아 편두통 환자의 임상적 특징을 알아보았으며, 이전의 진단기준과 비교하였을 때 새로 개정된 진단 기준에서 지속시간을 1시간 이상, 부위를 양측성까지 포함시킴으로써 상당수의 환자들이 편두통으로 진단될 수 있었다.

Objective : Cervicogenic headache (CGH) is known to be mainly related with upper cervical problems. In this study, the effect of radiofrequency neurotomy (RFN) for lower cervical (C4-7) medial branches on CGH was evaluated. Methods : Eleven patients with neck pain and headache, who were treated with lower cervical RFN due to supposed lower cervical zygapophysial joint pain without symptomatic intervertebral disc problem or stenosis, were enrolled in this study. CGH was diagnosed according to the diagnostic criteria of the cervicogenic headache international study group. Visual analogue scale (VAS) score and degree of VAS improvement (VASi) (%) were checked for evaluation of the effect of lower cervical RFN on CGH. Results : The VAS score at 6 months after RFN was $2.7{\pm}1.3$, which were significantly decreased comparing to the VAS score before RFN, $8.1{\pm}1.1$ ($p$<0.001). The VASi at 6 months after RFN was $63.8{\pm}17.1%$. There was no serious complication. Conclusion : Our data suggest that lower cervical disorders can play a role in the genesis of headache in addition to the upper cervical disorders or independently.

두통은 인류의 가장 흔한 호소 중의 하나로 임상에서 흔히 보는 장애이다. 두통은 뇌막염, 뇌출혈, 또는 뇌종양과 같은 다른 질환의 증상일수 있으나, 또한 편두통이나 군발두통 등과 같은 질병 자체로 표현된다. 일차적으로 두통 장애의 역학이나 국제 두통학회의 진단기준을 이해하고 흔치 않으나 심각한 이차적인 두통장애와 감별에 관심을 둬야 한다. 환자가 일차 두통장애의 기준에 맞으면 신경학적 진단검사의 보충이 없어도 치료를 시작한다. 두통 유형, 표현 양상, 동통기간과 강도 등에 따라 진통소염제나 혼합진통제, 혈관작용의 항편두통 약물 또는 신경이완제나 corticosteroid등을 선택한다. 편두통의 빈도와 강도에 따라 예방치료가 보통 4~6개월간 조절한다. 긴장형 두통은 발작성과 만성두통으로 구분되나 치료적으로는 급성완화와 예방치료로 시도된다. 많은 만성매일두통 환자들이 진통제나 ergotamine을 과용하고 있으며 그들의 의존성과 내재된 갈등조절, 수면장애, 우울등으로 과용된 약물의 제한이 쉽지 않다. 치료의 첫단계는 약물을 끊고 조심스럽게 대치요법을 시행한다.

Purpose : VDT (visual display terminal syndrome) can affect individuals who monitor or who work or play using video screens, including those of smartphones. In general, headache symptoms from overuse of these screens can appear due to eye fatigue, muscle pain in the joints of wrists or fingers, and muscle pain in the neck or shoulders. Many studies in the literature have supported standards that seek to prevent these symptoms. The incidence of musculoskeletal diseases caused by the use of smartphones is expected to increase rapidly, particularly among children and young adults, and these diseases are expected to develop into a societal problem. Therefore, in this study we investigate whether tension headaches that develop from smartphone usage can affect forward neck posture, neck pain, and quality of life. Methods : A total of 93 students from University participated in this study. We divided participants into two groups, those with tension headaches (n = 25) and those without (n = 68) and took forward neck measurements. Headaches were classified according to criteria from the International Headache Society and involved bilateral headache position, quality of pressing or tightening pain, mild or moderate pain intensity, and none due to daily physical activity. We surveyed participants using the smartphone addiction diagnosis questionnaire, the Neck Disability Index (NDI), the Headache Impact Test (HIT-6), and the Quality of Life Questionnaire. Results : Although we found no significant differences in tension headaches due to smartphone addiction diagnosis (p = 0.25), SF-36 life quality assessment (p = 0.06), and cranio-vertebral angle (p = 0.07), we found significant differences from the HIT-6 and the NDI (p <.05). Conclusion : Tension headaches are not correlated with smartphone addiction, quality of life, and forward neck angle but do have a correlation with the degree of cervical dysfunction and the effects of the headaches.

Background: Current evidence suggests that intravenous magnesium sulfate might be effective for reducing migraine pain. In a recent pilot study, we showed that intravenous caffeine citrate could reduce the severity of migraine headache. The objective of this study is to investigate the efficacy of intravenous caffeine citrate vs. magnesium sulfate for management of acute migraine headache. Methods: We conducted a prospective quasi-experimental study from January until May 2016 in two educational medical centers of Shahid Beheshti University of Medical Sciences (Shoahadaye Tajrish Hospital and Imam Hossein Hospital), Tehran, Iran. The study included patients who were referred to the emergency department and met the migraine diagnosis criteria of the International Headache Society. Patients were allocated into 2 groups receiving either 60 mg intravenous caffeine or 2 g intravenous magnesium sulfate. The pain scores, based on the visual analog scale, were recorded on admission, as well as one and two hours after receiving the drug. A Chi-Square test and student t-test were used for analysis of baseline characteristics. A Mann-Whitney U test and Wilcoxon singed rank test were used to analyze differences in the visual analogue scale (VAS) score between and within the groups respectively. Results: In total, 70 patients (35 patients in each group) with the mean age of $33.1{\pm}11.3years$ were included (64.3% female). For the Caffeine citrate group, the median pain score decreased from 9.0 (2.0) to 5.0 (4.0) after one hour and to 3.0 (4.0) after two hours. For the magnesium sulfate group, the pain score decreased from 8.0 (2.0) to 2.0 (2.0) after one hour and to 0.0 (1.0) after two hours. Both intravenous caffeine citrate and intravenous magnesium sulfate reduced pain scores significantly but the magnesium sulfate group showed more improvement than the Caffeine citrate group after one hour (P < 0.001) and after two hours (P < 0.001). Conclusions: It is likely that both intravenous caffeine and intravenous magnesium sulfate can reduce the severity of migraine headache. Moreover, intravenous magnesium sulfate at a dose of 2 g might be superior to intravenous caffeine citrate 60 mg for the short term management of migraine headache in emergency departments.

Nociplastic pain by the "International Association for the Study of Pain" is defined as pain that arises from altered nociception despite no clear evidence of nociceptive or neuropathic pain. Augmented central nervous system pain and sensory processing with altered pain modulation are suggested to be the mechanism of nociplastic pain. Clinical criteria for possible nociplastic pain affecting somatic structures include chronic regional pain and evoked pain hypersensitivity including allodynia with after-sensation. In addition to possible nociplastic pain, clinical criteria for probable nociplastic pain are pain hypersensitivity in the region of pain to non-noxious stimuli and presence of comorbidity such as generalized symptoms with sleep disturbance, fatigue, or cognitive problems with hypersensitivity of special senses. Criteria for definitive nociplastic pain is not determined yet. Eight specific disorders related to central sensitization are suggested to be restless leg syndrome, chronic fatigue syndrome, fibromyalgia, temporomandibular disorder, migraine or tension headache, irritable bowel syndrome, multiple chemical sensitivities, and whiplash injury; non-specific emotional disorders related to central sensitization include anxiety or panic attack and depression. These central sensitization pain syndromes are overlapped to previous functional pain syndromes which are unlike organic pain syndromes and have emotional components. Therefore, nociplastic pain can be understood as chronic altered nociception related to central sensitization including both sensory components with nociceptive and/or neuropathic pain and emotional components. Nociplastic pain may be developed to explain unexplained chronic pain beyond tissue damage or pathology regardless of its origin from nociceptive, neuropathic, emotional, or mixed pain components.

목 적 : 소아와 청소년에서 반복적이고 수초에서 수분 지속되는 short lasting headaches (SLH)에 대해서 드물게 보고되고 있다. 이러한 두통은 성인 일차성 두통 진단 기준에 부합되는 경우가 많다. 이에 저자는 소아청소년에서 반복되고 짧게 지속되는 두통의 빈도와 임상적 특징, 치료와 예후에 대해서 알아보고자 하였다. 방 법 : 조선대학교병원 소아청소년과 외래를 2006년 4월부터 2007년 7월까지 방문한 두통환자 123명중 수초에서 30분 지속되는 두통을 반복해서 경험한 44명을 대상으로 하였다. 환자의 특성과 두통의 빈도, 지속시간, 심한정도, 두통에 의한 장애, 두통의 양상, 발생 장소 등에 대해서 알아보고, 치료와 예후에 대해서 분석하였다. 결 과 : SLH은 44명(35.8%)이었고, 남자 18명, 여자 26명이었다. 6세 미만에서는 45.5%, 6세 이상은 33.7%이었으며, 통계학적으로 의미 있게 6세 미만에서 더 높게 발생하였다(P=0.015). 나이는 평균 $9.24{\pm}3.13$세, 한 달 동안 두통의 빈도 $11.5{\pm}10.30$, 심한정도 $4.86{\pm}1.36$, PedMIDAS $7.97{\pm}17.51$이었으며, 방문 전 두통을 앓았던 기간은 $7.99{\pm}8.84$개월이었다. 일차성 자두통의 진단 기준에 적합한 경우는 8명(18.2%)이었다. SLH 환자의 나이, 두통의 빈도, 지속시간, 심한정도, PedMIDAS, 발생 전 기간과 가족력에서 남녀의 차이는 통계학적으로 의미 없었다. 양상은 누르는 듯한 두통이 30.2%로 가장 많았으며, 찌르는 듯한 27.9%, 박동성 18.6%, 둔한 11.6%, 쥐어짜듯이 7.0% 순이었다. 통증 위치는 이마가 52.4%로 가장 많았으며, 한쪽 옆이 28.6%, 양쪽 옆 7.1%, 뒤 머리 4.8% 순이었다. 지속시간은 6-15분이 36.4%로 가장 많았고, 1-5분이 27.3%, 16-30분 미만 25.0%, 1분 이하가 11.3%이었다. 심한 정도는 1-3점이 13.6%, 4-6점 75.0%, 7-10점 11.4%이었다. 치료로 비약물적 치료로 상담과 생활 방식의 교육만 한경우가 36.4%, 급성기 약물 치료 34.1%, 교육과 예방적 약물치료 18.2%, 급성기 약물 치료와 예방적 약물치료를 같이 한 경우 9.1%이었다. 3개월 뒤 방문시 초기 방분보다 두통의 빈도, 심한정도, 지속시간, 두통에 의한 장애 모두에서 통계학적으로 의미 있는 호전을 보였다(P<0.05). 결 론 : 소아청소년에서 SLH은 35.8%로 흔하나, 성인의 일차성 두통 진단기준에 합당한 경우는 일차성 자두통이 18.2%로 대부분 성인의 진단기준에 맞지 않아서 소아와 청소년에서 짧게 지속되는 두통의 정확한 진단이 어려운 경우가 많았다. 치료 후 예후는 대부분에서 좋았다. 이러한 두통의 임상적 특징과 두통 분류와의 관계를 더 명확하게 하기 위해서는 더 많은 자료에 의한 연구가 필요하다.

Objective : Occipital neuralgia is characterized by paroxysmal jabbing pain in the dermatomes of the greater or lesser occipital nerves caused by irritation of these nerves. Although several therapies have been reported, they have only temporary therapeutic effects. We report the results of pulsed radiofrequency treatment of the occipital nerve, which was used to treat occipital neuralgia. Methods : Patients were diagnosed with occipital neuralgia according to the International Classification of Headache Disorders classification criteria. We performed pulsed radiofrequency neuromodulation when patients presented with clinical findings suggestive occipital neuralgia with positive diagnostic block of the occipital nerves with local anesthetics. Patients were analyzed according to age, duration of symptoms, surgical results, complications and recurrence. Pain was measured every month after the procedure using the visual analog and total pain indexes. Results : From 2010, ten patients were included in the study. The mean age was 52 years (34-70 years). The mean follow-up period was 7.5 months (6-10 months). Mean Visual Analog Scale and mean total pain index scores declined by 6.1 units and 192.1 units, respectively, during the follow-up period. No complications were reported. Conclusion : Pulsed radiofrequency neuromodulation of the occipital nerve is an effective treatment for occipital neuralgia. Further controlled prospective studies are necessary to evaluate the exact effects and long-term outcomes of this treatment method.
