Work-related musculoskeletal disorders among physical therapists in Taiwan.

ABSTRACT: Work-related musculoskeletal disorders (WMSD) refer to musculoskeletal injuries caused by the occupation. Physical therapists (PTs) suffer from a high risk of WMSD despite their extensive knowledge in ergometrics and injury prevention. This study aims to discover the incidence and prevalence of WMSD among PTs using Taiwan's nationwide claims database. The trend of annual patients seeking rehabilitation and the prevalence of WMSD among PTs were presented. The age- and gender-specific incidence of WMSD were also calculated. The prevalence of WMSD in PTs varied from 6.1% to 75.2%, and the incidence ranged from 6.1 to 29.1 per 100 person-years during 1997 and 2012. For those aged ≤30 years, the incidence was higher in females than males (incidence rate ratio  = 1.08, 95% confidence interval [CI]: 1.02-1.14, P = .011), whereas for those aged from 31 to40 years, females had lower incidence of WMSD than males (incidence rate ratio  = 0.88, 95% CI: 0.80-0.96, P = .007). The patients/PTs ratio was higher (270.56-337.74) in 1998 and 2004 to 2007 and became stable (245.93-252.82) in 2008 to 2012, correlating with a rise in the WMSD prevalence in 1999 to 2007 and a steady prevalence after 2008 (63.5%-66.3%) in PTs. In conclusion, the risk of WMSD among PTs was positively correlated to the frequency of patients seeking rehabilitation service. In addition, age and gender were important risk factors for developing WMSD among PTs.

Risk of dementia in colorectal cancer patients receiving chemotherapy: A nationwide cohort study.

BACKGROUND: Studies have reported conflicting evidence regarding whether chemotherapy leads to dementia. This study aimed to determine whether chemotherapy increases dementia risk in Taiwanese patients with colorectal cancer (CRC). METHODS: Data from the Taiwan Cancer Registry and National Health Insurance Research Database were used. Patients newly diagnosed as having CRC between 2007 and 2015 without prior history of dementia or neurodegenerative disorders were identified. Based on whether they underwent chemotherapy, patients were divided into chemotherapy and non-chemotherapy groups. Those who later developed dementia were identified using validated diagnostic codes. The Fine and Gray subdistribution hazard model for all-cause dementia with competing risk of death was applied for all patients or each stratified group. RESULTS: A total of 76,130 patients with CRC were included, with 45,872 (60.25%) in the chemotherapy group and 30,258 (39.75%) in the non-chemotherapy group. A higher incidence of dementia was observed in the non-chemotherapy group compared with the chemotherapy group (3.75% vs. 2.40%, p < 0.0001), but the risk of dementia did not differ between the groups (adjusted subdistribution hazard ratio [HRSD] = 0.97, 95% confidence interval [CI]: 0.88-1.06, p = 0.492). In the stratified analysis, chemotherapy was a risk factor for dementia in patients aged > 80 years (adjusted HRSD = 1.20, 95% CI: 1.03-1.40, p = 0.0190), whereas gender, clinical cancer stage, comorbidities, surgery, and radiation therapy had no impact on the risk of dementia. CONCLUSION: Chemotherapy increased the risk of dementia in elderly patients with CRC, highlighting the necessity to monitor their cognitive function after chemotherapy.

The impact of antiseizure medications on polysomnographic parameters: a systematic review and meta-analysis.

BACKGROUND: Oral antiseizure medications (ASMs) are first-line treatments for patients with epilepsy. However, ASMs may alter sleep architecture, adversely affecting patient outcomes. The meta-analysis aimed to elucidate the effect of ASMs on sleep architecture. METHODS: PubMed, Embase, and Cochrane Central database (up to Febrary 2021) were searched for randomized control trials (RCT) with effects of ASMs on polysomnography parameters. A meta-analysis using a random-effects model was performed. We did not set limitation to the participants with underlying diagnosis of epilepsy. RESULTS: Eighteen randomized-controlled trials fulfilled the eligibility criteria. The effects of five main groups of ASMs (sodium channel blockers, calcium channel blockers, GABA enhancers, synaptic vesicle glycoprotein 2A [SV2A] ligand, and broad-spetrum ASMs) on slow-wave sleep (SWS), rapid eye movement (REM) sleep, and sleep efficiency (SE) were analyzed. Compared with placebo, calcium channel blockers and GABA enhancers significantly increased SWS. GABA enhancers also decreased REM sleep percentage, whereas calcium channel blockers significantly increased SE. Sodium channel blockers, SV2A ligand and broad-spectrum ASMs did not affect SWS, REM sleep, or SE. The subgroup analysis revealed that gabapentin, pregabalin, and tiagabine increased the percentage of SWS. Tiagabine also decreased REM sleep, whereas pregabalin increased SE. Finally, levetiracetam did not affect SWS, REM sleep, and SE. CONCLUSIONS: This meta-analysis indicated that ASMs can have a statistically significant effect on sleep parameters; the effect differs between ASMs.

The influence of friendship on migraine in young adolescents: A social network analysis.

OBJECTIVE: The current study explored whether the chances of having migraine are influenced by a youth's friendship with a migraineur. METHODS: The study was centered on a community-based non-referral cohort of eighth graders from two middle schools in Taiwan. Among the 642 recruited adolescent students, 610 (95%) (mean age 14.1 years, male ratio 51.2%) nominated three good friends and completed a validated headache questionnaire for migraine diagnosis at the follow-up survey 1 year later. To explore social influences on incident migraine, we used longitudinal statistical models to examine whether the development of migraine in one adolescent during the 1-year observational period was associated with that in his/her friends. RESULTS: Overall, 1700 social ties were established in the social network based on the reported lists of good friends. Randomization test for the homophily effect demonstrated that the students with migraine tended to cluster together in the social network even when those with incident migraine were also considered (p = 0.003). Besides, when friendship choices were mutual, the relative risk of an adolescent becoming a migraineur was 3.26 (95% CI: 1.25-8.47, p = 0.015) if his/her friend became a migraineur (induction) during the 1-year observational period. CONCLUSION: To the best of our knowledge, this is the first study to demonstrate that migraine may spread through social networks in young adolescents. Both homophily and induction effects are possibly contributory.

A prospective, observational study on conversion of clinically isolated syndrome to multiple sclerosis during 4-year period (MS NEO study) in Taiwan.

IMPORTANCE: CIS to MS conversion rates vary depending on population cohorts, initial manifestations, and durations of follow-up. OBJECTIVE: To investigate conversion rate of patients from CIS to MS and the prognostic significance of demographic and clinical variables in Taiwanese population. DESIGN: Nationwide, prospective, multi-centric, observational study from November 2008 to November 2014 with 4 years follow-up. SETTING: Multi-centre setting at 5 institutions in Taiwan. PARTICIPANTS: 152 patients having single clinical event potentially suggestive of MS in last 2 years were enrolled as consecutive sample. 33 patients were lost to follow-up and 16 patients did not complete the study.103 patients completed the study. INTERVENTION(S) (FOR CLINICAL TRIALS) OR EXPOSURE(S) (FOR OBSERVATIONAL STUDIES): Natural progression from first episode of CIS to MS or NMO was observed. MAIN OUTCOME(S) AND MEASURE(S): Variables analysed were 'proportion of patients converting to MS or NMO after first episode of CIS', 'duration between first episode of neurological event and diagnosis of MS', 'status of anti-AQP4 IgG' and 'length of longest contiguous spinal cord lesion in MS patients'. Association between baseline characteristics and progression to MS from CIS was analyzed using multiple logistic regression. Multivariate time dependent effect of baseline characteristics on progression to MS was plotted. RESULTS: 14.5% patients with CIS converted to MS after 1.1 ± 1.0 years with greater predisposition (18.8%) in those having syndromes referable to the cerebral hemispheres. Conversion rate from ON to MS was 9.7%. 90.9% patients had mild disease course. 46.7% patients had abnormal MRIs at baseline, with 0.6±0.5 contrast enhanced lesions. 'Below normal BMI' and 'MRI lesion load (≥ 4 lesions)' were identified as risk indicators for the development of MS. Amongst the patients who developed NMO as diagnosed by modern criteria, 80% were positive for anti-AQP4 IgG antibody. CONCLUSIONS AND RELEVANCE: 'Below normal BMI' and 'number of demyelinating lesions (≥4)' are significant predictors of conversion from CIS to MS. A low conversion rate to MS in Taiwanese CIS patients and majority of them having a mild course and minimal disability suggest the roles of geographic, genetic and ethnic factors. TRIAL REGISTRATION: Non-trial observational study.

Longitudinal risk factors for suicidal thoughts in depressed and non-depressed young adolescents.

OBJECTIVE: Evidence regarding the role of risk factors in the longitudinal course of suicidal ideation among young adolescents is lacking. We aimed to assess the effects of a range of risk factors, including obesity, academic performance, child-parent relationship, physical maltreatment, and depressive symptoms, on the development of suicidal ideation in young adolescents. METHODS: A school cohort of seventh and eighth graders was followed for 1 year and differences in the risk factors distributions were examined between depressed and non-depressed adolescents. We further examined risk factors for newly developed suicidal ideation and persistent suicidal ideation in the groups of adolescents based on the presence of suicidal ideation at baseline. RESULTS: A total of 1710 young adolescents were recruited, among whom 8.2% were categorised as having clinically significant depression. For depressed adolescents, being obese was associated with a three-fold increased risk of having suicidal ideation. For non-depressed adolescents, physical maltreatment, a feeling of not being cared about and sub-threshold depressive symptoms were the risk factors. The latter two remained robust in predicting newly developed suicidal ideation. CONCLUSION: The current study may shed light on the differential strategies to address suicidal thoughts in depressed and non-depressed adolescents. We emphasise the importance of recognition and management of sub-threshold depressive symptoms and the relevance of obesity, physical maltreatment and a feeling of not being cared about to suicide prevention programmes in early adolescence.

Risk of breast cancer recurrence in patients receiving manual lymphatic drainage: a hospital-based cohort study.

BACKGROUND: This retrospective cohort study evaluated whether manual lymphatic drainage (MLD) therapy increases the risk of recurrence of breast cancer. METHODS: We analyzed 1,106 women who were diagnosed with stage 0-3 breast cancer between 2007 and 2011 and experienced remission after surgery and adjuvant therapy. The patients were divided into two groups: group A (n=996), in which patients did not participate in any MLD therapy, regardless of whether they developed breast cancer-related lymphedema (BCRL) after cancer treatment; and group B (n=110), in which patients participated in MLD therapy for BCRL. All patients were monitored until October 2013 to determine whether breast cancer recurrence developed, including local or regional recurrence and distant metastasis. Patients who developed cancer recurrence prior to MLD therapy were excluded from analysis. Risk factors associated with cancer recurrence were evaluated using Cox proportional hazards models. RESULTS: During the monitoring period, 166 patients (15.0%) developed cancer recurrence, including 154 (15.5%) in group A and 12 (10.9%) in group B. The median period from surgery to cancer recurrence was 1.85 (interquartile range 1.18-2.93) years. Independent risk factors for cancer recurrence were tumor histological grading of grade 3, high number (≥3) of axillary lymph node invasion, and a large tumor size (>5 cm). Factors protecting against recurrence were positive progesterone receptor status and receiving radiation therapy. Receiving MLD therapy was not an outcome factor in multivariate analyses (hazard ratio 0.71, 95% confidence interval 0.39-1.29, P=0.259). CONCLUSION: MLD is a gentle procedure that does not increase the risk of breast cancer recurrence in patients who develop BCRL.

Potential cognitive decline linked to angiotensin-converting enzyme gene but not hypertension: Evidence from cognitive event-related potentials.

OBJECTIVES: The aims of the present study were to investigate the effect of hypertension and angiotensin-converting enzyme (ACE) genotypes on cognitive event-related potentials (ERPs), and whether the impact of ACE genotypes on P300 is related to the influence of hypertension. METHODS: Using the Cognitive Abilities Screening Instrument (CASI), we recruited 97 mentally healthy middle-aged and older adults. Medical histories were collected, and blood pressure, ACE insertion/deletion polymorphisms and ERPs in an auditory oddball task were measured for all participants. RESULTS: When the participants were stratified according to the presence or absence of hypertension, there were no differences in CASI score, percentage of ACE genotypes and ERPs. The subjects with the D/D homozygote displayed lower amplitude and longer latency of P300, although there were no differences in CASI score and the percentage of hypertension. CONCLUSIONS: The subjects with the D/D genotype tended to have decreased amplitude and prolonged latency of P300 ERPs which reflected subtle cognitive impairment. There were no associations between hypertension, CASI score and P300 measurements. SIGNIFICANCE: Using ERPs, potential cognitive decline was linked to ACE genotypes, independently of the effect of hypertension.

Role of physiotherapy and patient education in lymphedema control following breast cancer surgery.

INTRODUCTION: This retrospective cohort study evaluated whether education in combination with physiotherapy can reduce the risk of breast cancer-related lymphedema (BCRL). METHODS: We analyzed 1,217 women diagnosed with unilateral breast cancer between January 2007 and December 2011 who underwent tumor resection and axillary lymph node dissection. The patients were divided into three groups: Group A (n=415), who received neither education nor physiotherapy postsurgery; Group B (n=672), who received an educational program on BCRL between Days 0 and 7 postsurgery; and Group C (n=130), who received an educational program on BCRL between Days 0 and 7 postsurgery, followed by a physiotherapy program. All patients were monitored until October 2013 to determine whether BCRL developed. BCRL risk factors were evaluated using Cox proportional hazards models. RESULTS: During the follow-up, 188 patients (15.4%) developed lymphedema, including 77 (18.6%) in Group A, 101 (15.0%) in Group B, and 10 (7.7%) in Group C (P=0.010). The median period from surgery to lymphedema was 0.54 years (interquartile range =0.18-1.78). The independent risk factors for BCRL included positive axillary lymph node invasion, a higher (>20) number of dissected axillary lymph nodes, and having undergone radiation therapy, whereas receiving an educational program followed by physiotherapy was a protective factor against BCRL (hazard ratio =0.35, 95% confidence interval =0.18-0.67, P=0.002). CONCLUSION: Patient education that begins within the first week postsurgery and is followed by physiotherapy is effective in reducing the risk of BCRL in women with breast cancer.

The benefit of early rehabilitation following tendon repair of the hand: A population-based claims database analysis.

STUDY DESIGN: A retrospective cohort. INTRODUCTION: The benefits of early rehabilitation after hand tendon repair have not been analyzed using population-based datasets. PURPOSE OF THE STUDY: to analyze whether early rehabilitation reduces the resurgery risk and the use of rehabilitation resources. METHODS: Patients (n = 1219) who underwent hand tendon repairs followed by rehabilitation were identified from a nationwide claims database and divided into 3 groups: early (<1 wk after tendon repair), intermediate (1-6 wk), or late (>6 wk) rehabilitation. The resurgery rate and the use of rehabilitation resources after tendon repair were calculated. Cox proportional hazards models were used to evaluate the relevant predictors of resurgery. RESULTS: The early rehabilitation group exhibited the lowest resurgery rate and used the fewest rehabilitation resources. Compared with late rehabilitation, early or intermediate rehabilitation conferred protective effects against resurgery in patients without a concomitant upper-limb fracture. CONCLUSION: Our findings suggest the benefit of early rehabilitation after hand tendon repair. LEVEL OF EVIDENCE: 4.

Incidence and risk factors of chronic daily headache in young adolescents: a school cohort study.

OBJECTIVES: This study investigated the incidence and risk factors of chronic daily headache (CDH) and its major subtypes in young adolescents. METHODS: A field cohort of 3342 adolescents aged 13 to 14 was established in 3 middle schools in Taitung, Taiwan, from 2005 to 2007. Participants without CDH at baseline were annually followed up for 1 to 2 years using the same questionnaires, including the Adolescent Depression Inventory and Pediatric Migraine Disability Assessment. The neurologists made the headache diagnoses based on clinical interviews and headache diaries. The person-time incidence rates and risk factors of incident CDH and its subtypes (ie, chronic migraine [CM] and chronic tension-type headache [CTTH]) were calculated by using Cox proportional hazards models. RESULTS: The cohort completed 5586 person-years (PYs) of follow-up. Sixty-three subjects (21 boys/42 girls) developed incident CDH with an incidence rate of 1.13 per 100 PYs, including 37 with CM (0.66 per 100 PYs) and 22 with CTTH (0.39 per 100 PYs). Thirty-three subjects (52%) had a baseline diagnosis of migraine. The independent risk factors for incident CDH included female gender, acute family financial distress, obesity, higher headache frequency, and a baseline diagnosis of migraine. A higher headache frequency was the only identical risk factor for CDH, CM, and CTTH. A baseline diagnosis of migraine and obesity were significant predictors for both CM and CDH. Female gender was a significant predictor for both CTTH and CDH. CONCLUSIONS: Incident CDH was common in young adolescents. Some risk factors for incident CM and CTTH were different.

Transient visual disturbances in adolescents: migrainous feature or headache-accompanied phenomenon?

OBJECTIVES: To investigate the prevalence, characteristics and clinical correlates of transient visual disturbances (TVDs) in adolescents with headaches. METHODS: We surveyed headache-related TVDs in the past three months in two middle schools. All the ninth-grade students filled-in the questionnaires including demographics, a validated headache questionnaire, and visual phenomenon questions embedding the Visual Aura Rating Scale (VARS). TVDs were defined as transient visual phenomena corresponding to a headache attack, but not visual aura, i.e. VARS

Surgical treatment of the synkinetic eyelid closure in Marin-Amat syndrome.

Marin-Amat syndrome is a synkinesis which develops following facial nerve palsy and manifests as an involuntary eyelid closure when the jaw is opened. We presented 2 patients with Marin-Amat syndrome. One patient developed this syndrome after Bell palsy and the other after cross-facial nerve graft and free functional muscle transfer. Surgery was planned with an attempt to resect the target muscle innervated by the aberrant nerve to eliminate the paradoxical synkinesis. We developed a new surgical technique by resection of the upper or lower preseptal orbicularis oculi muscle (OOM) to treat the synkinetic eyelid closure effectively in both cases. Since the pretarsal and orbital OOM remain intake, patients can close their eyes smoothly. No recurrence or any sequela was noted after long-term follow-up. Careful preoperative electromyography study and detailed dynamic facial image analysis of both upper and lower lid OOM are very important to locate the synkinetic muscle. To the best of our knowledge, this is the first report to treat Marin-Amat syndrome successfully with surgical resection of preseptal OOM.

Histamine regulates cyclooxygenase 2 gene activation through Orai1-mediated NFκB activation in lung cancer cells.

Histamine, an important chemical mediator, has been shown to regulate inflammation and allergic responses. Stimulation of histamine receptors results in a significant increase in cytoplasmic Ca(2+), which could be mediated by inositol trisphosphate (IP(3))-dependent store-operated Ca(2+) channels (SOC). However, the link between histamine-mediated signaling and activation of inflammatory genes such as cyclooxygenase 2 (COX-2) is still unknown. Our study indicated that the COX-2 protein was highly expressed in human lung cancer cells. Following stimulation with 10 µM of histamine, both store-operated Ca(2+) entry (SOCE) and COX-2 gene expression were evoked. Histamine-mediated COX-2 activation can be prevented by 2-APB and SKF-96365, SOC channel inhibitors. In addition, deletion analysis of the COX-2 promoter suggested that the region between -80 bp and -250 bp, which contains NFκB binding sites, is the key element for histamine-mediated signaling. Knocking down ORAI1, one of the essential molecules of store-operated calcium channels, attenuated histamine-mediated COX-2 expression and NFκB activation. These results indicated that ORAI1-mediated NFκB activation was an important signaling pathway, responsible for transmitting histamine signals that trigger inflammatory reactions.

Relationship between childhood physical maltreatment and migraine in adolescents.

OBJECTIVE: To study the relationship between childhood physical abuse and migraine in adolescents. BACKGROUND: Childhood maltreatment might lead to an increased probability of migraine among adults. Nevertheless, the relationship between migraine and childhood abuse is unknown in adolescents. METHODS: We enrolled 3955 students, ages 13-15, from 3 middle schools. Each participant completed a validated headache questionnaire for headache diagnosis and the Adolescent Depression Inventory (ADI). A classification of physical maltreatment was given to students who reported they had been beaten by parents or elder family members. RESULTS: A total of 926 (23.4%) students were diagnosed with migraine or probable migraine occurring within the 3 months prior to the survey. Physical maltreatment was reported by 945 (23.9%) students, including a frequency of "rarely" in 762 (19.3%) students and "sometimes or often" in 183 (4.6%). The students reporting physical maltreatment were more likely to suffer migraine or probable migraine compared with those who reported no physical maltreatment (30.3% vs 21.3%, odds ratios = 1.6, 95%, CI: 1.4-1.9, P < .001). A higher frequency of physical maltreatment was associated with a higher likelihood of migraine diagnosis (21.3% vs 28.3%, vs 38.3%, "never" vs "rarely" vs "sometimes or often maltreated," respectively, P < .001). In addition, among the students diagnosed with migraine, those reporting physical maltreatment had higher mean ADI scores, a higher frequency of headaches, and a greater proportion of severe headaches. CONCLUSIONS: The results suggest that physical maltreatment is associated with migraine in adolescents and that physical maltreatment may be related to an increase in the frequency and intensity of headaches in adolescents with migraines. A history of physical maltreatment may be helpful in the treatment of adolescents suffering from migraine.

Symmetric atrophy of bilateral distal upper extremities and hyperIgEaemia in a male adolescent with Hirayama disease.

Hirayama disease is a rare neuromuscular disorder with peak age of onset at 15 to 17 years among young males. We report a male adolescent presenting with symmetric weakness and atrophy of bilateral upper extremities progressing for 2 years before stabilizing. Otherwise, he did not complain of any sensory disturbance. Electrophysiological findings revealed motor neuron damage at the C7-T1 spinal segments. Cervical magnetic resonance imaging revealed a high-signal mass of posterior dural sac at the C5-T5 vertebral level during neck flexion. Specifically, he had elevated serum total immunoglobulin E level, which had been postulated to be a precipitating factor in Hirayama disease. Early recognition and intervention of this unique neuromuscular disorder is important to avoid ongoing damage to motor neurons. Through this report, we would like to emphasize the crucial role of a pediatric neurologist in averting the progression of Hirayama disease at an early stage.

Headache disability among adolescents: a student population-based study.

OBJECTIVE: To examine the extent and to identify the relevant predictors of headache disabilities in adolescents. BACKGROUND: Headaches are common in adolescents but their impact and related factors have not been extensively studied in adolescent communities. METHOD: We recruited and surveyed 3963 students aged 13-15 from 3 middle schools using self-administered questionnaires. The questionnaires were used to make 3 assessments: (1) headaches were diagnosed using a validated headache questionnaire; (2) headache disabilities were evaluated using the 6-question Pediatric Migraine Disability Assessment; (3) depression was measured using the Adolescent Depression Inventory. RESULTS: The student response rate was 93%. In total, 484 students (12.2%) had migraines with or without auras, 444 (11.2%) had probable migraines, and 1092 (27.6%) had tension-type headaches. The students with migraine had the highest Pediatric Migraine Disability Assessment scores (10.7 +/- 20.0); whereas, the students with tension-type headaches had the lowest scores (2.0 +/- 4.4). Logistic regression analyses indicated that there were a number of independent predictors for moderate to severe headache-related disability (Pediatric Migraine Disability Assessment score > or =31), including a migraine or probable migraine diagnosis, a higher depression score, severe headache intensity, and frequent headaches. CONCLUSIONS: The Pediatric Migraine Disability Assessment provides a simple tool to measure the impact of headaches in adolescents. Adolescents with migraine headaches suffered the greatest level of disability. Higher depression scores were associated with more severe headache-related disabilities in adolescents, independent of headache frequency and severity.

Chronic daily headache in adolescents: an 8-year follow-up study.

OBJECTIVE: To assess the long-term outcome of a community-based adolescent cohort with chronic daily headache (CDH). METHODS: A field sample of 122 adolescents aged 12-14 years with CDH was established in 2000 (baseline) with short-term follow-up studies in 2001 and 2002. In 2008, the cohort was re-interviewed by physicians via telephone to determine the headache profile for the past year, including Migraine Disability Assessment (MIDAS), a headache disability questionnaire. Presence of CDH was defined as >or=15 headache days/month, average >or=4 hours/day for >3 months. Outcome measures included headache frequency, MIDAS score, and presence of CDH in 2008. RESULTS: A total of 103 subjects (26 male/77 female, mean age 21.6 +/- 0.9 years) completed the study (response rate 84.4%). The average monthly headache frequency was 4.7 +/- 6.0 (0-30) days. Twenty-eight (27.2%) subjects had moderate or severe headache disability (MIDAS >or=11). Twelve (12%) subjects met CDH criteria, with chronic migraine (n = 10, 83%) as the most common subtype. Two (2%) subjects overused medications. From 2000 to 2008, the frequencies of migraine diagnoses were fairly consistent in this cohort. Presence of migraine at baseline predicted poorer outcome of all 3 measures. Additionally, CDH onset <13 years old, duration >or=2 years, and medication overuse predicted either higher headache frequencies or presence of CDH in 2008. CONCLUSIONS: This long-term follow-up study revealed a marked decline in the frequency of chronic daily headache (CDH). However, one fourth of patients still had significant headache disability. Migraine history was a major factor in evolution of CDH into young adulthood. Early onset and longer duration of CDH implied a protracted disease course.

Migraine and suicidal ideation in adolescents aged 13 to 15 years.

BACKGROUND: Awareness is growing among clinicians of the importance of suicidal ideation in adolescents. OBJECTIVES: To investigate the relationship between migraine and suicidal ideation in a nonreferred sample of adolescents. METHODS: This study surveyed migraine and depression in three middle schools in Taitung County, Taiwan. All students completed the questionnaires, including demographics, a validated headache questionnaire, the Adolescent Depression Inventory (ADI), and the Pediatric Migraine Disability Assessment (PedMIDAS) questionnaire. This study used the presence or absence of suicidal ideation as indicated by the ADI for the analysis. RESULTS: A total of 3,963 (2,040 male and 1,923 female; mean age 14.0 +/- 0.9 years) adolescents (93% of the target cohort) completed this study. Suicidal ideation was reported in 8.5% of the study group. Compared with nonmigraine subjects (6.2%), subjects with migraine displayed a higher frequency of suicidal ideation (16.1%; odds ratio [OR] = 2.9, 95% confidence interval [CI] 2.3-3.6; p < 0.001), especially those with migraine with aura (23.9%; OR = 4.6 [95% CI 3.0-7.0]; p < 0.001). Suicidal ideation was associated with higher headache frequency and headache-related disability as measured by the PedMIDAS. After controlling for depression score and sociodemographic characteristics, the association remained only for migraine with aura (adjusted OR = 1.79 [95% CI 1.07-2.99]; p = 0.025) and high headache frequency (>7 days/month; adjusted OR = 1.69 [95% CI 1.12-2.56]; p = 0.013) but not for migraine without aura or probable migraine or PedMIDAS score. CONCLUSIONS: This study identified a higher frequency of suicidal ideation in younger adolescents with migraine with aura or high headache frequency. These associations were independent of depressive symptoms. ADI = Adolescent Depression Inventory; AOR = adjusted odds ratio; CI = confidence interval; 5-HT = serotonin; ICHD-2 = International Classification of Headache Disorders, Second Edition; MINI-Kid = Mini-International Neuropsychiatric Interview-Kid; OR = odds ratio; PedMIDAS = Pediatric Migraine Disability Assessment.
