Abstract
BACKGROUND Nerve fibers related to pain and temperature sensation in the trigeminal nerve territory converge with the upper cervical spinal nerves from the level of the lower medulla oblongata to the upper cervical cord. This structure is called the trigemino-cervical complex and may cause referred pain in the territory of the trigeminal or upper cervical spinal nerves. CASE SERIES Here, we report three cases of paroxysmal neuralgia in the occipital region with mild conjunctivitis or a few reddish spots in the ipsilateral trigeminal nerve territory. The patients exhibited gradual progression of these reddish spots evolving into vesicles over the course of several days, despite the absence of a rash in the occipital region. The patients were diagnosed with trigeminal herpes zoster and subsequently received antiherpetic therapy. Remarkably, the neuralgia in the occipital region showed gradual amelioration or complete resolution before the treatment, with no sequelae reported in the occipital region. DISCUSSION The trigemino-cervical complex has the potential to cause neuralgia in the occipital region, as referred pain, caused by trigeminal herpes zoster. These cases suggest that, even if conjunctivitis or reddish spots appear to be trivial in the trigeminal nerve territory, trigeminal herpes zoster should be considered when neuralgia occurs in the ipsilateral occipital region.

Abstract
INTRODUCTION The impacts of migraine on daily life, including daily activities and fundamental health indicators (sleep and mental health), have not been described in detail for people with migraine in Japan. METHODS The cross-sectional ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE (OVERCOME [Japan]) study was conducted between July and September 2020. Impacts of migraine on housework, family/social/leisure activities, driving, and sleep were assessed using questions from the Migraine Disability Assessment (MIDAS), Migraine-Specific Quality-of-Life Questionnaire, and Impact of Migraine on Partners and Adolescent Children scales and questions developed for OVERCOME (Japan). The Migraine Interictal Burden Scale (MIBS-4) evaluated burden on days without headaches. Depression and anxiety were assessed with the Patient Health Questionnaire (PHQ-8) and Generalized Anxiety Disorder (GAD-7) scales, respectively. Impacts on daily life were also described across MIDAS/MIBS-4 categories. RESULTS Among 17,071 respondents with migraine, 24.8% required assistance with housework at least sometimes. Migraine interfered with relationships, leisure, and social activities at least sometimes for 31.8%, 41.6%, and 18.0% of respondents, respectively. Between headache days, 26.8% of respondents worried about planning social/leisure activities at least sometimes. Among respondents living with family (N = 13,548), migraine also had impacts on participation in and enjoyment of family activities. Among respondents who drove (N = 10,921), 43.9% reported that symptoms interfered with driving at least sometimes. Migraine interfered with sleep and mood at least sometimes for 52.7% and 70.7% of respondents, respectively. PHQ-8 and GAD-7 thresholds for clinical depression and anxiety were met by 28.6% and 22.0% of respondents, respectively. Impact of migraine on daily life increased with increasing severity of MIDAS/MIBS-4 categories. CONCLUSION The burden of migraine on daily activities, sleep, and mental health is substantial for people with migraine in Japan. In clinical practice, it is important to evaluate the impact of migraine on daily life in addition to migraine symptoms.

Abstract
OBJECTIVE To investigate the prescription patterns for patients aged 6-17 years with headaches in the REZULT database. METHODS We cross-sectionally investigated (Study 1) the pattern of prescription and the proportion of triptan overprescription (≥30 tablets/90 d of triptans) among patients diagnosed with headaches in 2020. Next, we longitudinally studied patients (Study 2) for more than two years from the initial headache diagnosis (July 2010 to April 2022). The number of prescribed tablets was counted every 90 days. RESULTS In Study 1, headache diagnoses were assigned to 62,568 of 543,628 (11.51%) patients, and 1524 of 62,568 (2.44%) patients received acute medication. Single nonsteroidal anti-inflammatory drugs and triptans were prescribed to 620/624 (99.36%) and 5/624 (0.80%) of patients aged 6-11 years, respectively, and 827/900 (91.89%) and 91/900 (10.11%) of patients aged 12-17 years, respectively. Triptan overprescription was observed in 11/96 (11.46%) patients, and 5/11 (45.45%) of those patients received prophylactic medication. In Study 2, 80,756/845,470 (9.55%) patients aged 6-17 years were diagnosed with headaches that persisted for at least two years. Over two years, 44/80,756 (0.05%) patients were overprescribed triptans, and 3408/80,756 (4.22%) patients were prescribed prophylaxis on at least one occasion. CONCLUSIONS Based on real-world data, the appropriate use of prophylactic treatment is still problematic. Overprescription of triptans was observed, although the number of patients was small.

Abstract
BACKGROUND The present study aimed to investigate prescription patterns for patients aged over 17 years with headaches in the REZULT database. METHODS We conducted a cross-sectional study (Study 1) of the proportion of over-prescription of acute medications (≥30 tablets/90 days for triptans, combination non-steroidal anti-inflammatory drugs (NSAIDs) and multiple types; ≥45 tablets/90 days for single NSAIDs) among patients with headache diagnosed in 2020. We longitudinally studied (Study 2) patients for >2 years from initial headache diagnosis (July 2010 to April 2022). The number of prescribed tablets was counted every 90 days. RESULTS In Study 1, headache was diagnosed in 200,055 of 3,638,125 (5.5%) patients: 13,651/200,055 (6.8%) received acute medication. Single NSAIDs were prescribed to 12,297/13,651 (90.1%) patients and triptans to 1710/13,651 (12.5%). Over-prescription was found in 2262/13,651 (16.6%) patients and 1200/13,651 (8.8%) patients received prophylactic medication. In Study 2, 408,183/6,840,618 (6.0%) patients were first diagnosed with headaches, which persisted for ≥2 years. Over time, the proportion of patients over-prescribed acute medications increased. Over 2 years, 37,617/408,183 (9.2%) patients were over-prescribed acute medications and 29,313/408,183 (7.2%) patients were prescribed prophylaxis at least once. CONCLUSIONS According to real-world data, prophylaxis remains poorly prescribed, and both acute and prophylactic treatment rates for headaches have increased over time.

Abstract
OBJECTIVE To evaluate quality of life (QoL) endpoints from two 12-week trials investigating fremanezumab efficacy and safety in Japanese/Korean patients with chronic (CM) or episodic (EM) migraine. BACKGROUND Migraine is a leading cause of disability and affects QoL considerably, interfering with work and daily activities, social and family life, and emotional wellbeing. METHODS This planned exploratory analysis used data from two multicenter, randomized, double-blind, placebo-controlled, parallel-group studies in which Migraine-Specific QoL (MSQoL; Role Function-Restrictive [RR], Role Function-Preventive [RP], and Emotional Function [EF] domains) scores and Patient Global Impression of Change (PGIC) scores were pre-specified QoL outcomes in individuals receiving monthly or quarterly fremanezumab or placebo. In both trials, MSQoL was assessed at baseline, and MSQoL and PGIC at Weeks 4, 8, and 12. PGIC responders had a score of ≥5 points, indicating significant improvement. RESULTS Mean baseline MSQoL scores were similar across groups in both CM (N = 565; RR, 60.3-61.5; RP, 78.5-80.0; EF, 69.0-71.4) and EM (N = 353; RR, 68.6-71.1; RP, 83.1-85.7; EF, 76.7-81.9) trials. In the CM trial, all three MSQoL domains improved in both fremanezumab groups at 12 weeks compared with placebo: least squares mean (LSM) and standard error (SE) change from baseline, p versus placebo (quarterly; monthly; placebo): RR 14.9 (1.3), p = 0.030; 15.1 (1.4), p = 0.020; 11.6 (1.3); RP 8.9 (1.1), p = 0.007; 8.6 (1.1), p = 0.013; 5.4 (1.1); EF 13.3 (1.5), p < 0.001; 12.5 (1.5), p = 0.003; 7.5 (1.5). In the EM trial, RR/EF domains improved in both fremanezumab groups compared with placebo: LSM change from baseline, p versus placebo (quarterly; monthly; placebo): RR 16.3 (1.4), p = 0.003; 16.4 (1.3), p = 0.002; 11.6 (1.4); EF 13.0 (1.3), p < 0.001; 11.5 (1.2), p = 0.004; 7.4 (1.3); RP improved in the quarterly group RP 8.6 (1.1), p = 0.010; 7.6 (1.1), p = 0.066; 5.4 (1.1). The proportion of PGIC responders at Week 12 was greater in the monthly and quarterly fremanezumab groups compared with the placebo group in the CM (96/182 [52.7%] and 98/180 [54.4%] vs. 68/179 [38.0%]; p < 0.05) and EM trial (81/118 [68.6%] and 86/113 [76.1%] vs. 38/111 [34.2%]; p < 0.001). CONCLUSION Patients with EM/CM receiving monthly or quarterly fremanezumab, for a duration of 12 weeks, showed significant improvements in their QoL.

Abstract
BACKGROUND Knowledge of patient outcomes and treatment effectiveness associated with acute migraine treatments in Japan is lacking. OBJECTIVE To describe patient-reported outcomes (PROs) and treatment effectiveness in three acute treatment groups from OVERCOME (Japan): over-the-counter (OTC) only, prescription nonsteroidal anti-inflammatory drugs/acetaminophen (Rx-NSAIDs/ACE) only, and triptans. METHODS OVERCOME (Japan) was an observational, cross-sectional, population-based web survey of people with migraine (July-September 2020). PROs, including the Migraine-Specific Quality of Life Questionnaire (MSQ), Migraine Interictal Burden Scale (MIBS-4), Migraine Disability Assessment (MIDAS), and Work Productivity and Activity Impairment Questionnaire: Migraine (WPAI-M), were compared pairwise between treatment groups. Logistic regression was used to examine treatment effectiveness. RESULTS The analysis included 9075 survey respondents (OTC only: n = 5791; Rx-NSAIDs/ACE only: n = 751; triptans: n = 2533). Triptan users reported the lowest MSQ scores, most severe disability (MIDAS: 20.7% versus 6.3% and 11.6%) and severe interictal burden (MIBS-4: 50.1% versus 21.2% and 19.8%), and greatest work impairment (WPAI-M: 50.4% versus 32.2% and 30.8%) compared with the OTC and Rx-NSAIDs/ACE groups, respectively. Treatment effectiveness was very poor-to-poor for 60.9%, 43.1%, and 47.6% of the triptan, OTC, and Rx-NSAIDs/ACE groups, respectively. Severe interictal burden was significantly associated with insufficient treatment effectiveness (odds ratios, severe versus no burden: 0.47 [95% confidence interval: 0.40-0.54], 0.56 [0.35-0.89], and 0.41 [0.32-0.52], for the OTC, Rx-NSAIDs/ACE, and triptan groups, respectively). CONCLUSION People with high migraine burden used triptans for acute treatment, but many reported poor treatment effectiveness. Education may be required to promote better treatments, including earlier introduction of migraine-specific acute and preventive medications.

Abstract
OBJECTIVE We developed an artificial intelligence (AI)-based headache diagnosis model using a large questionnaire database from a headache-specializing clinic. BACKGROUND Misdiagnosis of headache disorders is a serious issue and AI-based headache diagnosis models are scarce. METHODS We developed an AI-based headache diagnosis model and conducted internal validation based on a retrospective investigation of 6058 patients (4240 training dataset for model development and 1818 test dataset for internal validation) diagnosed by a headache specialist. The ground truth was the diagnosis by the headache specialist. The diagnostic performance of the AI model was evaluated. RESULTS The dataset included 4829/6058 (79.7%) patients with migraine, 834/6058 (13.8%) with tension-type headache, 78/6058 (1.3%) with trigeminal autonomic cephalalgias, 38/6058 (0.6%) with other primary headache disorders, and 279/6058 (4.6%) with other headaches. The mean (standard deviation) age was 34.7 (14.5) years, and 3986/6058 (65.8%) were female. The model's micro-average accuracy, sensitivity (recall), specificity, precision, and F-values for the test dataset were 93.7%, 84.2%, 84.2%, 96.1%, and 84.2%, respectively. The diagnostic performance for migraine was high, with a sensitivity of 88.8% and c-statistics of 0.89 (95% confidence interval 0.87-0.91). CONCLUSIONS Our AI model demonstrated high diagnostic performance for migraine. If secondary headaches can be ruled out, the model can be a powerful tool for diagnosing migraine; however, further data collection and external validation are required to strengthen the performance, ensure the generalizability in other outpatients, and demonstrate its utility in real-world settings.

Abstract
OBJECTIVE We prospectively performed the Itoigawa Headache Awareness Campaign from August 2021 to June 2022, with two main interventions, and evaluated its effectiveness. BACKGROUND Headache is a common public health problem, but its burden could be reduced by raising awareness about headache and the appropriate use of acute and prophylactic medication. However, few studies on raising headache awareness in the general public have been reported. METHODS The target group was the general public aged 15-64. We performed two main interventions synergistically supported by other small interventions. Intervention 1 included leaflet distribution and a paper-based questionnaire about headache during COVID-19 vaccination, and intervention 2 included on-demand e-learning and online survey through schools. In these interventions, we emphasize the six important topics for the general public that were described in the Clinical Practice Guideline for Headache Disorders 2021. Each response among the two interventions' cohorts was collected on pre and post occasions. The awareness of the six topics before and after the campaign was evaluated. RESULTS We obtained 4016 valid responses from 6382 individuals who underwent vaccination in intervention 1 and 2577 from 594 students and 1983 parents in intervention 2; thus, 6593 of 20,458 (32.2%) of the overall working-age population in Itoigawa city experienced these interventions. The percentage of individuals' aware of the six topics significantly increased after the two main interventions ranging from 6.6% (39/594)-40.0% (1606/4016) to 64.1% (381/594)-92.6% (1836/1983) (p < 0.001, all). CONCLUSIONS We conducted this campaign through two main interventions with an improved percentage of individuals who know about headache. The two methods of community-based interventions could raise headache awareness effectively. Furthermore, we can achieve outstanding results by doing something to raise disease awareness during mass vaccination, when almost all residents gather in a certain place, and school-based e-learning without face-to-face instruction due to the COVID-19 pandemic.

Abstract
BACKGROUND We investigated the prevalence of headache, migraine, and medication-overuse headache (MOH) among children and adolescents through a school-based online questionnaire. We also investigated the triggers for migraine among them and the effect of the COVID-19 pandemic on headache frequency. METHODS Children and adolescents aged 6-17 y.o. completed an online questionnaire. Migraine, MOH was defined as The International Classification of Headache Disorders Third edition. Factor and clustering analyses were performed for migraine triggers. The effect of the coronavirus disease 2019 (COVID-19) pandemic on headache frequency was also asked. RESULTS Of the 2489 respondents, the prevalence of headache, migraine, and MOH were 36.44%, 9.48%, and 0.44%, respectively. Up to 70% of the respondents with headaches complained of the disturbance to daily life, but about 30% consulted doctors. The migraine triggers were grouped into 5 factors by factor analysis. The sensitivities of the migraineurs against the factors were divided into 3 clusters. Cluster 1 had stronger sensitivity for several triggers. Cluster 2 was sensitive to weather, smartphones, and video games. Cluster 3 had less sensitivity for triggers. Cluster 2 less consulted doctors even though the burden of migraine was enormous. During the COVID-19 pandemic, 10.25% of respondents increased headache attacks, while 3.97% decreased. CONCLUSIONS This is the first detailed study on headache prevalence in Japanese students from elementary school to high school in one region. The burden of headaches is large among children and adolescents, and the unmet needs of its clinical practice should be corrected.

Abstract
OBJECTIVES Tension-type headache (TTH) is the most prevalent type of primary headache disorder. Its acute pharmacotherapy is acetaminophen or non-steroidal anti-inflammatory drugs based on the Japanese Clinical Practice Guideline for Headache Disorders 2021. With Japan's aging population, however, the number of TTH patients with comorbidities that have been treated by analgesics is increasing. Under this context, it is sometimes difficult to select an acute pharmacotherapy for TTH. Kakkonto, Japanese traditional herbal kampo medicine, is empirically used for TTH. We hypothesized that kakkonto has efficacy for TTH with painful comorbidities. MATERIALS AND METHODS We prospectively collected 10 consecutive TTH patients who had already taken analgesics for comorbidities. We prescribed 2.5 g of kakkonto (TJ-1), and patients took it. A numerical rating scale for pain before and 2 hours after kakkonto intake was evaluated. RESULTS Eight women and 2 men were included. The mean age was 71.0 ± 13.4 years old. Four patients had lower back pain, 2 had lumbar spinal stenosis, 2 had knee pain, 1 had neck pain, and 1 had shoulder myofasciitis. Celecoxib was used for 4 patients, acetaminophen for 3, loxoprofen for 2, and a combination of tramadol and acetaminophen for 1, as routinely used analgesics. The median numerical rating scale statistically improved from the median of 4 to that of 0. There were no side effects of kakkonto. CONCLUSION Kakkonto showed efficacy as an acute medication for TTH with comorbidities that have been treated by analgesic.

Abstract
BACKGROUND MONONOFU, a multicenter, randomized, double-blind, placebo-controlled phase 2 study of Japanese patients with migraine, was pivotal for lasmiditan approval in Japan. However, treatment-emergent adverse events (TEAEs) were more common than in global studies. A detailed safety profile would assist patient management. RESEARCH DESIGN AND METHODS Safety assessments in MONONOFU included specific terms reported, frequency, severity, time to onset, duration, TEAE management, common TEAE risk factors, and TEAE-efficacy associations. RESULTS Of 846 participants, 691 were assessed for safety. The proportion of participants reporting ≥1 TEAE was 23.4% with placebo and 70.9% with lasmiditan; 87.3% of TEAEs with lasmiditan were mild. The most frequent TEAEs with lasmiditan, dizziness (39.4%) and somnolence (19.3%), started ≤1 hour postdose (median durations: 2.5 and 3.3 hours, respectively). Higher lasmiditan dose, but not patient factors including body size, was identified as a clinically meaningful predictor of dizziness and somnolence. There were no adverse consequences of neurological TEAEs, which did not appear to adversely affect lasmiditan efficacy. CONCLUSIONS In the MONONOFU study, TEAEs appeared typically mild, transient, and self-limiting. Lasmiditan may represent a useful and well-tolerated acute treatment option for smaller (body mass index <30 kg/m2) patients and Asian patients with migraine.

Abstract
INTRODUCTION Rapid onset and sustained efficacy are important for acute migraine treatment. Global phase 3 trials have demonstrated the early onset and sustained efficacy of the 5-HT1F receptor agonist lasmiditan. In this prespecified analysis of the MONONOFU study, we assessed the onset and sustained efficacy of lasmiditan in Japanese patients with migraine. METHODS MONONOFU was a multicenter, randomized, placebo-controlled, phase 2 study conducted in Japan (May 2019-June 2020). Eligible adults with migraine (N = 846; modified intent-to-treat population, N = 682) were randomized 7:3:7:6 to placebo, lasmiditan 50 mg, 100 mg, or 200 mg, taken orally within 4 h of moderate-to-severe migraine onset. Patients recorded headache severity and symptoms predose and 0.5-48 h postdose. Sustained and modified sustained pain freedom were defined as patients who were headache pain-free 2 h postdose and had no pain (sustained pain freedom) or had mild or no pain (modified sustained pain freedom) at 24 or 48 h without rescue/recurrence medications. Efficacy outcomes were analyzed by logistic regression. Patients also recorded the actual time of pain-free and of meaningful pain relief (Kaplan-Meier analysis). RESULTS Compared with placebo, significantly more lasmiditan-treated (100 or 200 mg) patients were headache pain-free, had pain relief, were free of their most bothersome symptom, or had total migraine freedom (no headache or migraine-associated symptoms) within 30-60 min. Median time to pain-free was 9.26, 6.88, 2.75, and 2.30 h in placebo, 50-mg, 100-mg, and 200-mg lasmiditan groups, respectively. Significantly greater proportions of patients treated with 100 (19.7-29.5%) or 200 mg (21.1-35.7%) lasmiditan had sustained or modified sustained pain freedom at 24 or 48 h compared with placebo (10.4-15.8%). CONCLUSION This prespecified analysis of data from MONONOFU has confirmed that the efficacy of lasmiditan is rapid in onset and sustained in patients with moderate-to-severe migraine in Japan.

Abstract
OBJECTIVE The medication-overuse headache (MOH) prevalence has not been investigated in a general Japanese population. We performed questionnaire-based survey and revealed MOH prevalence and its characteristics. We also performed clustering to obtain insight for MOH subgrouping. METHODS In this cross-sectional study, the 15-64-year-old population was investigated in Itoigawa during their COVID-19 vaccination under the national policy. MOH was defined as ≥ 15 days/month plus self-report of use of pain medications ≥ 10 or 15 days/month in the last 3 months. Ward method and k-means + + were used to perform clustering MOH patients. RESULTS Among 5865 valid responses, MOH prevalence was 2.32%. MOH was common among females and the middle-aged. Combination-analgesic is the most overused as 50%. MOH had aggravation by routine physical activity, moderate or severe pain, and migraine-like, compared to non-MOH. The 136 MOH patients could be grouped into 3 clusters. Age and frequency of acute medication use were essential factors for clustering. CONCLUSIONS This is the first study of MOH prevalence in Japan. Most MOH characteristics were similar to previous reports worldwide. Public awareness of proper headache treatment knowledge is still needed. Clustering results may be important for subtype grouping from a social perspective apart from existing clinical subtypes.

Abstract
PURPOSE In two 24-week migraine prevention studies in Japan, erenumab was associated with significantly greater reductions in migraine frequency versus placebo over Weeks 13-24 (primary endpoint). This post hoc analysis evaluated the onset of efficacy within the first 4 weeks after the initiation of erenumab from the 24-week double-blind periods of these studies. METHODS Placebo-adjusted differences in least squares mean (LSM) change from baseline in weekly migraine days (WMD) were assessed weekly in each study and by migraine type (episodic (EM]/chronic [CM]) (Study 20170609). RESULTS A total of 407 patients from Study 20120309 (70 mg: N = 135; 140 mg: N = 136; placebo: N = 136) and 261 patients from Study 20170609 ([EM] 70 mg: N = 78; placebo: N = 81; [CM] 70 mg: N = 52; placebo: N = 50) were included. For Study 20120309, onset of efficacy was observed as early as Week 1 in favor of erenumab versus placebo. Placebo-adjusted differences in LSM (95% confidence interval [CI]) change from baseline in WMD at Week 1 were -0.38 (-0.71 to -0.05; p = .022) and -0.49 (-0.82 to -0.16; p = .004) in favor of erenumab 70 and 140 mg, respectively. For Study 20170609, significant placebo-adjusted differences were observed with erenumab 70 mg at Week 1 in patients with EM (LSM [95% CI]: -0.55 [-0.97 to -0.12; p = .012]), and at Week 2 in patients with CM (LSM [95% CI]: -0.81 [-1.53 to -0.09; p = .028]) and for the overall population (LSM [95% CI]: -0.71 [-1.09 to -0.33; p < .001]). CONCLUSIONS Erenumab treatment significantly reduced WMD compared with placebo. Onset of erenumab efficacy occurred as early as Week 1 in patients with migraine.

Abstract
INTRODUCTION Using data from the ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE study in Japan (OVERCOME [Japan]), we describe the current status of the acute treatment of migraine in Japan. METHODS OVERCOME (Japan) was a cross-sectional, observational, population-based web survey of people with migraine in Japan (met modified International Classification of Headache Disorders criteria or had a physician diagnosis of migraine) conducted between July and September 2020. Respondents reported current acute medication use and effectiveness (assessed using the Migraine Treatment Optimization Questionnaire [mTOQ-4]). Cardiovascular history and risk factors of the respondents were also recorded. Potential unmet acute treatment needs were defined as insufficient effect of current acute treatments (mTOQ-4 score ≤ 5), a history of oral triptan use (and not currently taking any triptan), potential contraindications to triptans due to cardiovascular comorbidities, and/or cardiovascular risk factors. RESULTS In total, 17,071 people with migraine in Japan completed the survey; 14,869 (87.1%) of these were currently using acute treatments. Poor effectiveness of current acute treatment was reported by 7170 respondents (42.0%), 900 respondents (5.3%) were former triptan users, 1759 (10.3%) had contraindications to triptans, and 9026 (52.9%) reported at least one cardiovascular risk factor. Overall, 12,649 (74.1%) of OVERCOME (Japan) respondents were categorized into one or more of these groups and were considered to have potential unmet acute treatment needs. CONCLUSION Almost three-quarters of people with migraine in Japan may have potential unmet needs for acute treatment of migraine. There are substantial opportunities for improving care for people with migraine in Japan, including prescription of novel acute medications.

Abstract
OBJECTIVE The ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE study in Japan (OVERCOME [Japan]) aimed to provide an up-to-date assessment of migraine epidemiology in Japan. METHODS OVERCOME (Japan) was a cross-sectional, population-based web survey of Japanese adults recruited from consumer panels. People with active migraine (met modified International Classification of Headache Disorders, 3rd edition [ICHD-3] criteria or had a self-reported physician diagnosis of migraine) answered questions about headache features, physician consultation patterns, and migraine medication use. The burden and impact of migraine were assessed using Migraine Disability Assessment (MIDAS) and Work Productivity and Activity Impairment scales. RESULTS In total, 231,747 respondents accessed the screener, provided consent, and were eligible for the survey. The migraine group included 17,071 respondents (mean ± SD age 40.7 ± 13.0 years; 66.5% female). ICHD-3 migraine criteria were met by 14,033 (82.2%) respondents; 9667 (56.6%) self-reported a physician diagnosis of migraine. The mean number of monthly headache days was 4.5 ± 5.7 and pain severity (0-10 scale) was 5.1 ± 2.2. In the migraine group, 20.7% experienced moderate to severe migraine-related disability (MIDAS score ≥ 11). Work productivity loss was 36.2% of work time missed, including 34.3% presenteeism. Only 57.4% of respondents had ever sought medical care for migraine/severe headache. Most respondents (75.2%) were currently using over-the-counter medications for migraine; 36.7% were using prescription nonsteroidal anti-inflammatory drugs, and only 14.8% were using triptans. Very few (9.2%) used preventive medications. CONCLUSIONS Unmet needs for migraine health care among people with migraine in Japan include low rates of seeking care and suboptimal treatment.

Abstract
Background These subgroup analyses of a Phase 3, randomized, double-blind, placebo-controlled study evaluated the efficacy and safety of erenumab 70 mg in Japanese migraine patients with/without prior preventive treatment failure(s) (“failed-yes” and “failed-no” subgroups) and with/without concomitant preventive treatment (“concomitant preventive-yes” and “concomitant preventive-no” subgroups). Methods Overall, 261 patients were randomized; 130 and 131 patients to erenumab 70 mg and placebo, respectively. Subgroup analyses evaluated the change from baseline to Months 4–6 in mean monthly migraine days (MMD) (primary endpoint), achievement of a ≥50% reduction in mean MMD, and change from baseline in mean monthly acute migraine-specific medication (MSM) treatment days. Treatment-emergent adverse events were also evaluated. Results Of the 261 patients randomized, 117 (44.8%) and 92 (35.3%) patients were in the failed-yes and concomitant preventive-yes subgroups, respectively. Erenumab 70 mg demonstrated consistent efficacy across all subgroups, with greater reductions from baseline in mean MMD versus placebo at Months 4–6 (treatment difference versus placebo [95% CI], failed-yes: − 1.9 [− 3.3, − 0.4]; failed-no: − 1.4 [− 2.6, − 0.3]; concomitant preventive-yes: − 1.7 [− 3.3, 0.0]; concomitant preventive-no: − 1.6 [− 2.6, − 0.5]). Similar results were seen for achievement of ≥50% reduction in mean MMD and change from baseline in mean monthly acute MSM treatment days. The safety profile of erenumab 70 mg was similar across subgroups, and similar to placebo in each subgroup. Conclusion Erenumab was associated with clinically relevant improvements in all efficacy endpoints and was well tolerated across all subgroups of Japanese migraine patients with/without prior preventive treatment failure(s) and with/without concomitant preventive treatment.

Abstract
Objectives Erenumab is a human anti‐calcitonin gene‐related peptide receptor monoclonal antibody approved for migraine prevention. Global studies have demonstrated its efficacy in chronic and episodic migraine (EM). Here we report the outcomes from a Phase 3 study of erenumab in Japanese patients with chronic migraine (CM) or EM. Methods Japanese patients with EM (<15 headache days/month, including ≥4 migraine days/month) or CM (≥15 headache days/month, including ≥8 migraine days/month) were randomized 1:1 to placebo or erenumab 70 mg once monthly for a 24‐week double‐blind treatment phase (DBTP). The primary endpoint of change from baseline in mean monthly migraine days (MMD) over months 4, 5, and 6 of the DBTP was compared between erenumab and placebo groups. Secondary efficacy and safety endpoints were also assessed. Results A total of 261 patients were randomized to placebo (n = 131) or erenumab 70 mg (n = 130); all patients were included in the efficacy and safety analyses. The mean (standard deviation) MMD at baseline was 11.84 (5.70) for the placebo group and 12.40 (5.99) for erenumab 70 mg. The mean (standard error) change in MMD was –1.98 (0.38) for the placebo group (n = 131) and –3.60 (0.38) for erenumab 70 mg (n = 130). The difference in MMD reduction between groups was −1.67 (95% CI: –2.56, –0.78, p < 0.001) for EM and –1.57 (95% CI: –3.39, 0.24, p = 0.089) for CM. Adverse events (AEs) were consistent with earlier studies. The most frequent AEs (placebo, erenumab) were nasopharyngitis (28.2% and 26.9%, respectively), back pain (4.6% and 5.4%), and constipation (0.8% and 4.6%). Conclusion Treatment with erenumab 70 mg once monthly demonstrated favorable efficacy and safety findings in Japanese patients with EM or CM.

Abstract
Background Primary headaches are widespread and costly public health problems. However, there are insufficient medical resources for their treatment in Japan due to two reasons. First, the numbers of headache specialists and clinics remain insufficient. Second, neurologists and neurosurgeons mainly treat headaches in Japan. However, they mainly work as general stroke neurologists, so they cannot focus on primary headache treatment. To solve these problems, we preliminarily developed a deep learning (DL)-based automated diagnosis model from patients' Japanese unstructured sentences in the medical questionnaire using a DL framework. We hypothesized that the model would reduce the time and burden on both doctors and patients and improve their quality of life. Methods We retrospectively investigated our primary headache database and developed a diagnosis model using the DL framework (Prediction One, Sony Network Communications Inc., Japan). We used age, sex, date, and embedding layer made by the medical questionnaire's natural language processing (NLP). Results Eight hundred and forty-eight primary headache patients (495 women and 353 men) are included. The median (interquartile range) age was 59 (40-74). Migraine accounted for 46%, tension-type headache for 47%, trigeminal autonomic cephalalgias for 5%, and other primary headache disorders for 2%. The accuracy, mean precision, mean recall, and mean F value of the developed diagnosis model were 0.7759, 0.8537, 0.6086, and 0.6353, which were satisfactory. Conclusion The DL-based diagnosis model for primary headaches using the raw medical questionnaire's Japanese NLP would be useful in performing efficient medical practice after ruling out the secondary headaches.

Abstract
Background Sodium valproate is a standard drug for first‐line prophylactic treatment of migraine. However, little information is available of its use in Japanese patients. Aim To evaluate the effectiveness and safety of an extended‐release tablet of sodium valproate in the prophylactic treatment for Japanese patients with migraine by postmarketing surveillance. Methods This was a prospective, multicenter and non‐interventional observation study in routine clinical practice. A total of 1222 patients with migraine of all age groups (aged <10 to ≤80 years) and both sexes (17.3% men and 82.7% women) from 169 sites were enrolled. Results Migraine frequency during a 4‐week period was reduced from 10.2 ± 6.0 days in 1040 patients to 5.0 ± 4.6 days in 944 patients (P < 0.001): 70.8% of patients experienced remission of migraine by ≥30%, 59.0% by ≥50% and 11.8% by ≥100%. Multivariate analysis and stratification sampling showed that this sodium valproate tablet was the most effective in patients with more migraine days, and complete remission was observed in 29% of patients whose migraine days were less than 3 days per 4 weeks at baseline. The extended‐release tablet of sodium valproate reduced migraine intensity and duration of migraine attacks. The incidence of adverse drug reactions was 6.3% (67/1070 patients) and well tolerated. However, four pregnancies were discovered in this survey. Conclusions This first large observation study in Japan suggests that an extended‐release tablet of sodium valproate is effective and safe for the prophylactic treatment of patients with migraine in routine clinical practice.

Abstract
Background: Antiplatelet agents are used during endovascular treatment of cerebral aneurysms to prevent thromboembolic complications. Objective: The aim of this study was to investigate the efficacy of clopidogrel for the prevention of thromboembolic complications during elective coil embolization of unruptured cerebral aneurysms. Methods: Sixty-three patients prospectively received oral clopidogrel 75mg/day from 3 days before and for 1 day after the procedure at our institute (Kohnan Hospital, Sendai, Japan) during 2007. Results: At 24 hours post-coiling, significantly less high-intensity areas, detected by MRI with diffusion-weighted imaging (MRI-DWI), were observed in clopidogrel-treated patients compared with a historical control cohort of aspirin (acetylsalicylic acid)-treated patients (13/63 [20.6%] vs 27/69 [39.1%]; p = 0.02), primarily due to a statistically significantly lower rate during repair of small (<10mm) lesions (p = 0.008).Also, the rate of periprocedural thromboembolic events was lower in the clopidogrel than the aspirin cohort (2/63 [3.2%] vs 5/69 [7.2%]; p = 0.3). Conclusions: Clopidogrel was generally well tolerated with no signs of hemorrhagic complications or liver dysfunction.

Abstract
The purpose of this study was to clarify the incidence and features of acute cerebrovascular diseases in Yamagata Prefecture, by comparing with those in other prefectures reported in previous studies. Consecutive 13,639 cases of acute stroke were prospectively registered to Yamagata Society in Treatment for Cerebral Stroke (YSTCS) between January 1, 1998 and December 31, 2002. Cerebral infarction (CI), intracerebral hemorrhage (CH), subarachnoid hemorrhage (SAH) and transient ischemic attack (TIA) were observed in 58.4%, 25.8%, 11.4% and 4.4% of the patients, respectively. The frequencies of CH and SAH (37.2%) in Yamagata Prefecture were higher than those reported in other studies (p < 0.01). In addition, time from onset to admission in Yamagata Prefecture was longer than that reported in others(p< 0.01). This study was one of the largest stroke registration studies in Japan enrolling 13,639 patients. In addition, computed tomography (CT) and/or magnetic resonance image (MRI) was performed on admission in all patients. Diagnosis was made by a neurologist or a neurosurgeon based on CT and/or MRI findings. Our results might accurately reflect current status of stroke patients in Yamagata Prefecture.

Abstract
Background and Purpose—
Caspase-8 and caspase-9 are essential proteases of the extrinsic and intrinsic apoptotic pathways, respectively. We investigated whether neuroprotection associated with overexpression of heat-shock protein 70 (Hsp70), a natural cellular antiapoptotic protein, is mediated by caspase-8 and caspase-9 signaling in the neonatal mouse brain after hypoxia/ischemia (H/I) injury.
Methods—
Postnatal day 7 transgenic mice overexpressing rat Hsp70 (Hsp70 Tg) and their wild-type (Wt) littermates underwent unilateral common carotid artery ligation followed by 30 minutes of exposure to 8% O
2
. The expression of apoptotic proteins was quantified by Western blot analysis, and the specific interaction between Hsp70 and apoptotic protease activating factor 1 (Apaf-1) was determined by coimmunoprecipitation.
Results—
Hsp70 overexpression reduced cytosolic translocation of cytochrome c without affecting the levels of Apaf-1 and pro–caspase-9 24 hours after H/I. The expression of these apoptotic proteins in the naïve neonatal brains was also not affected by Hsp70 overexpression. Reduced caspase-9 cleavage occurred in Hsp70 Tg mice compared with Wt littermates 24 hours after H/I and correlated with increased binding of Hsp70 and Apaf-1. Increased cellular Fas-associated death domain–like interleukin-1β–converting enzyme inhibitory protein (FLIP) expression and decreased caspase-8 cleavage were also observed in Hsp70 Tg compared with Wt mice 24 hours after H/I.
Conclusions—
Our results suggest that the extrinsic and intrinsic apoptotic pathways mediate the neuroprotective effects of Hsp70 overexpression in neonatal H/I, specifically by upregulating FLIP and sequestering Apaf-1, leading to reduced cleavage of caspase-8 and caspase-9.

Abstract
Enriched environment (EE) has been shown to increase neurogenesis in the adult brain. The aim of this study is to determine the effect of EE and spatial learning on neurogenesis following ischemic stroke. Male adult SD rats were subjected to sham surgery or distal middle cerebral artery occlusion (MCAO). MCAO induced a transient increase followed by a sustained depression of progenitor cell proliferation and neuroblast production below baseline level in both ipsilateral and contralateral DG compared to sham. Increased neuronal differentiation and neurogenesis in the DG were observed in both sham and MCAO rats following 8 weeks in the EE combined with spatial learning, compared to rats housed in the standard environment. EE/Learning also restored the total number of neuroblasts in the DG after MCAO compared to sham. Furthermore, EE/learning enhanced the density of NeuN positive cells in the ischemic penumbra, though no new neurons were detected in this region.

Abstract
Apoptosis is implicated in neonatal hypoxic/ischemic (H/I) brain injury among various forms of cell death. Here we investigate whether overexpression of heat shock protein (Hsp) 70, an antiapoptotic protein, protects the neonatal brain from H/I injury and the pathways involved in the protection. Postnatal day 7 (P7) transgenic mice overexpressing rat Hsp70 (Tg) and their wild-type littermates (Wt) underwent unilateral common carotid artery ligation followed by 30 mins exposure to 8% O(2). Significant neuroprotection was observed in Tg versus Wt mice on both P12 and P21, correlating with a high level of constitutive but not inducible Hsp70 in the Tg. More prominent injury was observed in Wt and Tg mice on P21, suggesting its continuous evolution after P12. Western blot analysis showed that translocation of cytochrome c, but not the second mitochondria-derived activator of caspase (Smac)/DIABLO and apoptosis-inducing factor (AIF), from mitochondria into cytosol was significantly reduced in Tg 24 h after H/I compared with Wt mice. Coimmunoprecipitation detected more Hsp70 bound to AIF in Tg than Wt mice 24 h after H/I, inversely correlating with the amount of nuclear, but not cytosolic, AIF translocation. Our results suggest that interaction between Hsp70 and AIF might have reduced downstream events leading to cell death, including the reduction of nuclear AIF translocation in the neonatal brains of Hsp70 Tg mice after H/I.

Abstract
Hypoglycemia-induced brain injury is a significant obstacle to optimal blood glucose control in diabetic patients. Severe hypoglycemia triggers a cascade of events in vulnerable neurons that may culminate in cell death even after glucose normalization. A key event in this cascade is the activation of poly(ADP-ribose) polymerase-1 (PARP-1). Activated PARP-1 consumes cytosolic NAD, and because NAD is required for glycolysis, hypoglycemia-induced PARP-1 activation may render cells unable to use glucose even when glucose availability is restored. Pyruvate, however, can be metabolized in the absence of cytosolic NAD. Here we tested whether pyruvate could improve the outcome in rats subjected to insulin-induced hypoglycemia by terminating hypoglycemia with either glucose alone or glucose plus pyruvate. In the four brain regions studied--CA1, subiculum, dentate gyrus of the hippocampus, and piriform cortex--the addition of pyruvate reduced neuron death by 70-90%. Improved neuron survival was also observed when pyruvate delivery was delayed for up to 3 h. The improved neuron survival was accompanied by a sustained improvement in cognitive function as assessed by the Morris water maze. These results suggest that pyruvate may significantly improve the outcome after severe hypoglycemia by circumventing a sustained impairment in neuronal glucose utilization resulting from PARP-1 activation.

Abstract
Endoplasmic reticulum (ER) stress leads to activation of caspase-12, which in turn can lead to activation of caspase-3 and cell death. Here we report that transient acidosis induces ER stress and caspase-12-mediated cell death in mouse astrocytes. After a 3-hour incubation at pH 6.0, astrocytes exhibited delayed cell death associated with nuclear condensation and fragmentation. Cell death was reduced by the protein synthesis inhibitor cycloheximide, further suggesting an active cell death program. Acidosis increased the expression of the ER chaperone protein GRP-78, indicative of ER stress. Acidosis also increased caspase-12 mRNA expression, caspase-12 protein expression, cleavage of caspase-12 to its active form, and activation of caspase-3. Each of these effects was suppressed in astrocytes pretreated with caspase-12 antisense phosphorodiamidate morpholino oligodeoxynucleotides (PMOs). Caspase-12 antisense PMOs also reduced the cell death induced by acidosis. Immunoprecipitation studies showed dissociation of both caspase-12 and Ire1-alpha from GRP-78, thereby suggesting a mechanism by which acidosis can initiate the ER stress response. To evaluate caspase-12 activation in vivo, rats were subjected to middle cerebral artery ischemia-reperfusion. Immunostaining of brain sections harvested 24 hours later showed increased caspase-12 expression and nuclear condensation in astrocytes of the periinfarct region exposed to acidosis during ischemia. These findings suggest that acidosis induces ER stress and caspase-12 activation, and that these changes may contribute to delayed cell death after ischemia.

Abstract
Neurogenesis after brain injury not only leads to the replacement of damaged cells but might also contribute to functional recovery, suggesting the possibility of endogenous neural repair. We investigated the extent of hippocampal neural regeneration in a rat model of hypoglycemia. Two weeks after 30 min of insulin-induced isoelectric electroencephalogram, extensive neuronal loss was observed in the hippocampus, including area CA1 and dentate gyrus (DG). A transient increase in progenitor cell proliferation in the DG subgranular zone (SGZ) was detected, leading to an increase of immature neuroblasts 1-2 weeks after hypoglycemic insult. Most of the surviving newborn cells assumed a neuronal phenotype within 1 month in DG, a few cells near the site of granule-cell death becoming astroglia or microglia. No neuronal regeneration was observed in the CA1 after hypoglycemia, although dividing cells appeared to be astroglia or microglia in CA1 and dentate hilus. At 4 weeks after hypoglycemia, proliferative activity in the SGZ diminished below baseline in experimental versus control rats, with a subsequent reduction of neuroblasts. Morphological findings (doublecortin staining) suggest permanent progenitor cell loss in some areas of SGZ. Reduced neurogenesis in DG and lack of neuronal regeneration in CA1 may impede cognitive recovery after severe hypoglycemia injury.

Abstract
Increased neurogenesis after cerebral ischemia suggests that functional recovery after stroke may be attributed, in part, to neural regeneration. In this study, we investigated the role of neurogenesis in the behavioral performance of gerbils after cerebral global ischemia. We used ionizing radiation to decrease neural regeneration, and 2 weeks later cerebral global ischemia was induced by bilateral common carotid artery occlusion. One month after the occlusion, the animals were behaviorally tested. Irradiation alone reduced neurogenesis but did not change vascular or dendritic morphology at the time of behavioral testing. Neither did irradiation, ischemia, or combined treatment impair rotor-rod performance or alter open-field activity. Gerbils subjected to both irradiation and ischemia demonstrated impaired performance in the water-maze task, compared with those that received only ischemia, radiation, or no treatment. These impairments after cerebral global ischemia under conditions of reduced neurogenesis support a role for the production of new cells in mediating functional recovery.

Abstract
Severe hypoglycemia causes neuronal death and cognitive impairment. Evidence suggests that hypoglycemic neuronal death involves excitotoxicity and DNA damage. Poly(ADP-ribose) polymerase-1 (PARP-1) normally functions in DNA repair, but promotes cell death when extensively activated by DNA damage. Cortical neuron cultures were subjected to glucose deprivation to assess the role of PARP-1 in hypoglycemic neuronal death. PARP-1-/- neurons and wild-type, PARP-1+/+ neurons treated with the PARP inhibitor 3,4-dihydro-5-[4-(1-piperidinyl)butoxy]-1(2H)-isoquinolinone both showed increased resistance to glucose deprivation. A rat model of insulin-induced hypoglycemia was used to assess the therapeutic potential of PARP inhibitors after hypoglycemia. Rats subjected to severe hypoglycemia (30 min EEG isoelectricity) accumulated both nitrotyrosine and the PARP-1 product, poly(ADP-ribose), in vulnerable neurons. Treatment with PARP inhibitors immediately after hypoglycemia blocked production of poly(ADP-ribose) and reduced neuronal death by >80% in most brain regions examined. Increased neuronal survival was also achieved when PARP inhibitors were administered up to 2 hr after blood glucose correction. Behavioral and histological assessments performed 6 weeks after hypoglycemia confirmed a sustained salutary effect of PARP inhibition. These results suggest that PARP-1 activation is a major factor mediating hypoglycemic neuronal death and that PARP-1 inhibitors can rescue neurons that would otherwise die after severe hypoglycemia.

Abstract
OBJECTIVE Transgenic (Tg) mice overexpressing rat heat shock protein 70 (hsp70) demonstrated less infarction than did wild-type (WT) littermates after permanent focal cerebral ischemia. The purpose of this study was to determine whether neuronal injury and apoptosis were reduced in hsp70 Tg mice after transient focal ischemia. The effects of hsp70 overexpression were also evaluated after transient global ischemia or kainic acid (KA)-induced seizures, to verify the results in other excitotoxic stress models. METHODS Transient focal ischemia was produced with middle cerebral artery occlusion via intraluminal suture cannulation. Infarction volumes were assessed 24 hours after 30 minutes of middle cerebral artery occlusion. Transient global ischemia was produced with 25 minutes of bilateral common carotid artery occlusion. KA (30 mg/kg) was administered subcutaneously, and seizure activity was evaluated. The number of eosinophilic neurons was assessed in the CA1 region 72 hours after bilateral common carotid artery occlusion and in the CA3 region 24 hours after KA administration. RESULTS The infarction volume after transient middle cerebral artery occlusion was significantly smaller in hsp70 Tg mice than in WT mice (9.1 +/- 5.7 mm(3) versus 22.4 +/- 16.8 mm(3), P < 0.05). The number of eosinophilic neurons in the CA1 area after bilateral common carotid artery occlusion and in CA3 after KA injection was significantly lower in hsp70 Tg mice than in WT mice (949.1 +/- 1095.5 versus 2406.9 +/- 1380.3, P < 0.05, and 33.8 +/- 45.3 versus 119.4 +/- 112.1, P < 0.05, respectively). Fewer terminal deoxynucleotidyl transferase-mediated biotinylated deoxyuridine triphosphate nick end-labeling-positive cells were observed in hsp70 Tg mice than in WT mice in each model. CONCLUSION The results demonstrate that overexpression of hsp70 reduces neuronal injury after ischemia and seizures. The reduction in the number of terminal deoxynucleotidyl transferase-mediated biotinylated deoxyuridine triphosphate nick end-labeling-positive cells in hsp70 Tg mice suggests that hsp70 overexpression might reduce apoptotic cell death.

Abstract
Although protective effects of heat shock protein 70 (HSP70) overproduction after ischemic injury have been shown both in vitro and in vivo in neurons, the mechanisms are not fully understood. The hypothesis of this study is that transgenic mice overexpressing HSP70 (HSP70 Tg) show reduced mitochondrial cytochrome c release into cytosol and diminished apoptotic cell death after permanent focal ischemia in comparison to wild-type (Wt) mice. Permanent middle cerebral artery occlusion (pMCAO) was produced by intraluminal suture cannulation in HSP70 Tg and Wt mice. DNA fragmentation was evaluated with DNA gel electrophoresis and terminal deoxynucleotidyl transferase-mediated biotinylated UTP nick end labeling (TUNEL) 24 h after pMCAO. Mitochondrial cytochrome c release into cytosol was assessed with Western blotting and immunohistochemistry 4 h after pMCAO. Cytochrome c levels in the cytosolic fraction were significantly reduced and immunoreactivity of cytochrome c in both cortex and striatum was significantly less in HSP70 Tg mice compared with Wt mice after 4-h pMCAO. DNA laddering, which was clearly observed in Wt mice, was markedly attenuated in HSP70 Tg mice 24 h after pMCAO. The number of TUNEL-positive cells was significantly reduced in HSP70 Tg mice compared with Wt mice. Results are consistent with an association between overexpression of HSP70 and reduction of cytochrome c release with subsequent DNA fragmentation. This may contribute to the HSP70-mediated neuroprotective effect observed after cerebral ischemia.

Abstract
The viruses were isolated from the blood of sentinel cattle and Culicoides biting midges in the Kyushu district, southwestern Japan, in 1999 and identified by neutralization tests as Peaton (PEA) viruses. Before this study, PEA virus had been isolated in Australia only. The nucleotide identity of the nucleocapsid (N) protein encoded by the S segment ranged from 91.1 to 91.6% between the Australian and Japanese strains. A phylogenetic analysis of the N protein sequence revealed that the PEA virus strains are closely related to Aino (AIN) virus and suggested reassortment events for PEA and AIN viruses.

Abstract
UNLABELLED BACKGROUND AND OBJECTS: Matrix degradation, which is a critical event in the process of tumor invasion and metastasis, is considered to be caused by the action of proteolytic enzymes. METHODS We examined the gelatinolytic activity of matrix metalloproteinase (MMP)-9, and the activity of active and inactive forms of MMP-2 in five thymi, five noninvasive thymomas, eight invasive thymomas, and five thymic carcinomas by quantitative gelatinolytic zymography. RESULTS The gelatinolytic activity of active MMP-2 in five thymi was zero. The mean gelatinolytic activity of active MMP-2 was 0.020 +/- 0.015 in noninvasive thymoma, 0.084 +/- 0.098 in invasive thymoma and 0.246 +/- 0.194 in thymic carcinoma. The gelatinolytic activity of active MMP-2 correlated with the invasiveness of thymic epithelial tumors (Spearman rank correlation: r-value = 0.532). The gelatinolytic activity of active MMP-2 in three thymoma cases with microscopic capsular invasion was the same as that of noninvasive thymoma. When thymoma cases showing microscopic capsular invasion were classified into the "macroscopically noninvasive thymoma" group, the gelatinolytic activity of active MMP-2 correlated with the invasiveness of thymic epithelial tumors (Spearman rank correlation: r-value = 0.621). CONCLUSIONS The gelatinolytic activity of active MMP-2 significantly correlated with the invasiveness in thymic epithelial tumors. J. Surg. Oncol. 2001;76:169-175.

Abstract
BACKGROUND Epidemiological studies have demonstrated deteriorating effects of smoking on periodontal tissue. The aims of this study were to compare oxygen saturation of hemoglobin in the gingiva (GSo2) of smokers and non-smokers and to evaluate the chronic effect of smoking on gingival oxygen sufficiency. METHODS GSo2 was determined using tissue reflectance spectrophotometry in 110 papillary gingival sites of 62 smokers and 100 sites of 60 non-smokers. RESULTS No significant difference was found in GSo2 between smokers and non-smokers. In the model of ANOVA with covariates, age (P= 0.0048) and probing depth (P= 0.0012) had significant effects on GSo2. No significant effect was found in either smoking status (P= 0.3557) or the modified gingival index (MGI) (P= 0.3824). The interaction effect between smoking status and the MGI was highly significant (P = 0.0003) indicating that the effect of smoking status on the GSo2 should be compared at each level of the MGI score. GSo2 in healthy gingiva was significantly lower in smokers than non-smokers (P = 0.0014), while smokers showed higher GSo2 than non-smokers in moderately inflamed gingiva (P = 0.0356). The GSo2 in inflamed gingiva was significantly decreased compared with healthy gingiva in non-smokers (P = 0.0044), while smokers showed no significant difference between healthy and inflamed gingiva (P= 0.2772 to 0.8665). GSo2 in smokers was consistently and significantly lower than that of healthy gingiva of non-smokers (P = 0.0391 to 0.0004). CONCLUSIONS Smokers exhibit possibly lower function of oxygen sufficiency in healthy gingiva and reduced ability to adapt the function in inflamed gingiva than non-smokers. This suggests that smokers have functional impairments in the gingival microcirculation.

Abstract
BACKGROUND Smoking is associated with destructive periodontal disease. Pocket oxygen tension (pO2) is likely to be a major environmental determinant of the subgingival microflora, which is a primary etiological factor of the disease. This study aimed to compare the pocket pO2 in smokers and non-smokers with periodontal disease. METHODS Pocket oxygen tension was compared in 27 smokers and 34 non-smokers by considering 2 confounding factors, probing depth and oxygen saturation of hemoglobin (S(O2)), in the gingiva. The pO2 was determined using oxygen microelectrode by polarographic method with an electronic compensation circuit for subgingival temperature. Gingival S(O2) was determined using tissue reflectance spectrophotometry. RESULTS No significant difference was found in the modified gingival index and the plaque index between smokers and non-smokers. The pO2 was significantly lower in smokers (21.9+/-9.6 mmHg) than in non-smokers (33.4+/-8.4 mmHg). The difference was highly significant (P <0.0001) and was consistent when the confounding factors were considered. Correlation between the PO2 and probing depth approached statistical significance in smokers (r = -0.36, P = 0.0674) and significance in non-smokers (r = -0.41, P = 0.0174). Correlation of the PO2 to the gingival S(O2) was highly significant in non-smokers (r = 0.57, P = 0.0005), but no association was found in smokers (r = -0.08, P= 0.6975). CONCLUSIONS These findings indicate that pO2 is lower in smokers than in non-smokers, and that the pO2 in smokers is not influenced by gingival oxygen sufficiency. The present study may provide the basis of understanding environmental factors possibly associated with microbial flora in the pockets of smokers.

Abstract
BACKGROUND The substance P (SP) level in human gingival crevicular fluid (GCF) was studied in relation to clinical periodontal variables and to various indicators of host response in the GCF. METHODS GCF was collected from periodontal sites with gingival inflammation and shallow or moderately deep pocket in 48 subjects. The total amount of SP and the substances based on host response factors in a 30-s sample were determined by ELISA and enzymatic methods. RESULTS Significant correlation was found between SP and probing depth (r= 0.637, p<0.001), while correlation was weak between SP and either gingival (r= 0.177, p=0.23) or plaque index (r=0.008, p=0.96). SP also showed significant correlation with the indicators of host response: prostaglandin E2, aspartate aminotransferase, alkaline phosphatase, myeloperoxidase, interleukin-1beta, tumor necrosis factor-alpha, interleukin-8 and monocyte chemoattractant protein-1 (r=0.434-0.867, p<0.01-0.001). CONCLUSION These results indicate that neuropeptide SP in GCF may have a potential as an indicator of periodontal inflammation and the host response.

Abstract
An animal model of metastasis with features similar to those of lung cancer metastasis in humans is required for an understanding of the cellular and molecular mechanisms of human lung cancer metastasis. Ma-44 cell lines derived from human squamous cell lung cancer were percutaneously injected (2-3 x 10(4)) into the left lung of SCID mice. After orthotopic implantation, Ma-44 cell lines formed tumors in the left lung at a high rate (17/25, 68%), and many of those metastasized to mediastinal lymph nodes (13/17, 76%) by the 14th day, but not to other organs. After the ectopic implantation, the Ma-44 cell line inoculated subcutaneously (2-3 x 10(5)) formed a tumor at the inoculation site by the 28th day (all mice), but did not metastasize to any organs. The Ma-44 cell line inoculated intravenously (2-3 x 10(5)) formed metastases in the lungs (37/50, 74%), and these pulmonary metastases metastasized to the mediastinal lymph nodes at low rate (3/37, 8%) by the 14th day. The orthotopic sites of implantation are critical for the metastatic ability of transplanted tumors in SCID mice. Since non-small cell lung cancer (NSCLC) grows at the primary site in humans, lymphogenous metastasis occurs frequently, and blood-born metastasis occurs at moderate rate, our orthotopic SCID mice model was similar to the metastatic behavior of NSCLC in humans. Thus, this model may be useful for elucidating the mechanism of lymphogenous metastasis in human lung cancer, and testing the anti-metastatic efficacy of therapeutic agents in vivo.

Abstract
The cholecystokinin (CCK)-B/gastrin receptor binds two brain-gut hormones, CCK and gastrin, with high affinities. These peptides have a trophic effect on gastrointestinal cells expressing the receptor in vivo as well as in vitro. Recently, this receptor mRNA was reported to be expressed in immunocytes localized in the lamina propria of normal rat stomach mucosa. Here, we studied the receptor expression in human hematopoietic cells in order to determine whether they play a role in cell growth. The CCK-B/gastrin receptor mRNA was detectable in the polymorphonuclear (PMN) cells but not in the mononuclear cells of normal peripheral white blood cells by reverse transcription-polymerase chain reaction. The receptor transcript was, however, expressed in human leukemia cell lines (14 of 18 cell lines tested) derived from not only myeloid, but also T- and B- lymphoid lineages. The CCK-B/gastrin receptors on several leukemia cell lines were shown to be biologically active by demonstrating ligand-dependent cell proliferation in serum-deprived medium. Interestingly, a human CCK-B/gastrin receptor specific antagonist, YM022, but not its stereotype isoform, selectively inhibited the DNA synthesis of THP-1, MOLT-16, MOLT-14, and CCRF-CEM in the absence of exogenous peptide ligands. Further investigation revealed that these leukemia cell lines and normal PMN cells also expressed gastrin mRNA. These results suggest that growth of human leukemia cells is promoted by an autocrine mechanism through the CCK-B/gastrin receptors.

Abstract
Cholecystokinin (CCK)-B and gastrin receptors are expressed on a variety of human tumor cells. Recently, we have demonstrated that the human brain CCK-B receptors are identical to the gastrin receptors derived from the stomach mucosa, and that the brain-gut peptides, CCK-8 and gastrin I are mitogenic for mouse NIH 3T3 fibroblasts expressing human CCK-B/gastrin receptors (N-hCCKBR). In this report, we evaluated the antiproliferative potency of CCK-B/gastrin receptor antagonists by using N-hCCKBR cells. Among several antagonists, a benzodiazepine derivative, YM022 had the most potent activities in competing with [125I]CCK-8 or [125I]gastrin I binding, inhibition of CCK-8- or gastrin I-induced phosphoinositide hydrolysis and increasing cytoplasmic free calcium. Interestingly, a potent antagonist for rat CCK-B/gastrin receptors did not have such activities in N-hCCKBR cells. YM022 inhibited the CCK-8- or gastrin I-induced [methyl-3H]thymidine incorporation of N-hCCKBR cells in a dose-dependent manner. In the absence of exogenous peptide ligands, YM022 also inhibited the proliferation of several human cancer cell lines expressing the genes for both gastrin and its receptor. These results suggest that YM022 could intervene in the autocrine stimulation of human tumor cell lines through CCK-B/gastrin receptors. N-hCCKBR cells are an excellent tool to screen for novel human CCK-B/gastrin receptor antagonists possessing antiproliferative activity for human cancer cells.

Abstract
Cloning of CCK-B/gastrin receptor cDNAs showed that they possess the feature of serpentine G protein coupled receptors. In this study, the receptor mRNA was detected selectively in all SCLCs (10 cases) with a RT-PCR assay. By contrast, it was detectable in only one of thirteen squamous cell carcinomas or twenty-one adenocarcinomas of lung. Thus, CCK-B/gastrin receptor has been demonstrated to provide a novel molecular marker for the diagnosis of small cell lung cancer (SCLC) by using biopsy specimens.

Abstract
The brain-gut hormones, gastrin and cholecystokinin, have a trophic effect on the gastrointestinal mucosa in vivo and promote the growth of several neoplastic cell lines. In this study, cholecystokinin-B/gastrin receptor has been demonstrated to provide a novel molecular marker for the diagnosis of small cell lung cancer by using biopsy specimens. Physiological expression of the receptor mRNA is detectable in particular areas of the human brain, stomach, and pancreas but not in the lung. The receptor mRNA was detected selectively in all small cell lung cancer (10 cases) with a RT-PCR assay. By contrast, it was detectable in only 1 of 13 squamous cell carcinomas or 21 adenocarcinomas of the lung. Thus, the cholecystokinin-B/gastrin receptor could be an attractive therapeutic target for small cell lung cancer.

Abstract
A new type of staphylococcal exfoliative toxin (sET) was isolated from the culture filtrate of a Staphylococcus aureus strain isolated from a horse with skin infection including phlegmon. The new sET was purified by precipitation with 80% saturated ammonium sulfate, column chromatography on DEAE-cellulofine A-500, gel filtration on a Sephadex G-75 column, and polyacrylamide gel electrophoresis (7.5% polyacrylamide). The new sET elicited general exfoliation of the epidermis with the so-called Nikolsky sign when inoculated into both 3-day-old mice and 1-day-old chicks, whereas sETA and sETB from human strains of S. aureus caused exfoliation in a 3-day-old mouse alone and shET from a porcine strain of Staphylococcus hyicus caused exfoliation in 1-day-old chicks alone. Intraepidermal splitting was observed at the granular layer of the epidermis of mice inoculated with the new sET as well as those inoculated with sETA. Exfoliation at the germinative layer of the epidermis was also observed in the chicks inoculated with the new sET as well as those inoculated with shET. The new sET was serologically different from sETA, sETB, and shET and showed the same molecular weight on sodium dodecyl sulfate-polyacrylamide gel electrophoresis. It was thermolabile and lost its toxicity after being heated at 60 degrees C for 15 min. We propose that the new sET be designated as sETC.

Abstract
To compare the intracellular distribution of beta-adrenoceptors in isolated myocytes of SHR with that of age-matched WKY and to examine changes in the distribution with aging, we measured the number of cell surface and total beta-adrenoceptors in 6-(young groups) and 37-week old (old groups) SHR and WKY. The number of surface beta-adrenoceptors was significantly lower in 6-week old SHR compared with that in age-matched WKY. But there was no difference in the number of total beta-adrenoceptors between the two groups. The number of surface beta-adrenoceptors in old groups was significantly reduced compared with that in the young groups, in both SHR and WKY. However, the number of total beta-adrenoceptors in the old groups did not show any difference from that in the young groups. Isoproterenol-stimulated c-AMP formation in 6-week old SHR was significantly lower than that of WKY of the same age. Isoproterenol-stimulated c-AMP formation in the old groups was significantly reduced than that of the young groups in both SHR and WKY. These results suggested that (1) there may be a difference in the intracellular distribution of cardiac beta-adrenoceptors between 6-week old SHR and WKY, (2) the intracellular distribution of cardiac beta-adrenoceptors may be changed with aging, and (3) intracellular distribution might be related to the difference in c-AMP formation to beta-agonist.

Abstract
To explore possible roles of the sympathetic nervous system (especially the beta-adrenergic receptor and cAMP system) in the pathogenesis of ventricular fibrillation (VF), the authors examined changes in the number of myocardial beta-adrenergic receptors and the cAMP level in animals showing VF after experimental induction of myocardial ischemia. In animals that developed VF approximately 15 min after coronary ligation, the ischemic myocardium had a significantly larger number of beta-adrenergic receptors (90 +/- 8 fmol/mg protein) and a significantly higher level of cAMP (1.4 +/- 0.17 nmol/g weight) compared with the nonischemic area where the number of beta-receptors was 68 +/- 7 fmol/mg protein and the cAMP level was 0.80 +/- 0.20 nmol/g weight. In animals in which VF was electrically induced 20 min after coronary ligation, no elevation was recorded in the ischemic area in terms of the number of beta-adrenergic receptors (49 +/- 6 fmol/mg protein) and the level of cAMP (0.79 +/- 0.06 nmol/g weight). When animals were pretreated with a beta-blocker or a ganglion blocker, coronary ligation did not result in VF. In the ischemic area of these animals, no significant change was noted in the number of beta-adrenergic receptors (54 +/- 7 fmol/mg protein for animals pretreated with a beta-blocker, 56 +/- 3 fmol/mg protein for animals pretreated with a ganglion blocker). These results suggest that there is a strong correlation between the pathogenesis of VF (observed about 15 min after coronary ligation) and the increase of the number of beta-adrenergic receptors and cAMP levels.
