Selected AbstractsDeficient Knowledge Nursing Diagnosis: Identifying the Learning Needs of Patients With Cardiac DiseaseINTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 3 2010Luzia Elaine Galdeano PhD Assistência ao paciente; avaliação de processos; conhecimento; doença das coronárias; enfermagem OBJECTIVES., To identify the learning needs of patients with cardiac disease and the aspects of the disease and anesthetic and surgical procedures about which Brazilian patients have the greatest gaps in knowledge. METHODS., Eighty preoperative patients answered a General Evaluation Questionnaire, a Questionnaire to Evaluate Patient Knowledge, and the Mini-Mental State Exam. FINDINGS., Fifty-nine patients had learning needs. More than 50% of the patients were mistaken or unable to answer questions about the disease, and the goals of and type of surgery to be performed and anesthesia to be used. CONCLUSIONS., Most patients had poor performance on the questionnaire that assessed their knowledge about coronary artery disease and its treatment. PRACTICE IMPLICATIONS., This study can contribute to health professionals' assessment of patients' knowledge. OBJETIVOS., Identificar as necessidades de aprendizagem de pacientes com doença cardíaca e os aspectos da doença arterial coronariana e da revascularização do miocárdio do nos quais os pacientes brasileiros apresentam conhecimento deficiente. MÉTODO., Oitenta pacientes responderam o Questionário para avaliação geral, o Questionário para avaliar o conhecimento e o Mini-Exame do Estado Mental. RESULTADOS., Cinqüenta e nove pacientes apresentaram necessidade de aprendizagem. Mais de 50% dos pacientes erraram ou não souberam responder as questões referentes ao nome da doença, aos sinais e sintomas de complicação da doença, aos objetivos e tipo de cirurgia e anestesia. CONCLUSÃO., Muitos pacientes não apresentaram bom desempenho no questionário para medir conhecimento em relação à Doença Arterial Coronária e seu tratamento. IMPLICAÇÕES PRÁTICAS., Este estudo poderá contribuir para a avaliação do conhecimento dos pacientes por profissionais da saúde. [source] Right Ventricular Function in Congenital Heart Defects Assessed by Regional Wall MotionCONGENITAL HEART DISEASE, Issue 3 2010FSCAI, Michael R. Nihill MB ABSTRACT Objectives., To develop a simple method to assess right ventricular function by angiography. Background., Conventional methods of evaluating right ventricular function are inaccurate, cumbersome, and expensive. Methods., We analyzed biplane right ventricular angiograms taken in the posterior,anterior and lateral projections using software to measure right ventricular volumes and regional wall motion in 78 patients with normal hearts (n = 29), atrial septal defects (ASD n = 13), pulmonary valve stenosis (PVS n = 21), and postoperative atrial switch patients (n = 15). We also measured the shortening fraction (SF) from the midtricuspid annulus to the septum and correlated various angiographic measurements with the right ventricular (RV) ejection fraction. Results., The volume-overloaded patients (ASD) had larger end diastolic volumes and increased SF compared with normal patients, while the pressure-loaded patients (PVS) had normal volumes and SF. The postoperative atrial switch patients had decreased systolic function and increased end diastolic volume. The SF for all of the patients correlated with the ejection fraction (r= 0.785, P, .0001). Conclusions., A simple measurement of the end diastolic and end systolic distance from the midtricuspid annulus to the septum (SF) provides a good index of RV function by angiography and correlates well with RV ejection fraction. [source] Early Surgical Morbidity and Mortality in Adults with Congenital Heart Disease: The University of Michigan ExperienceCONGENITAL HEART DISEASE, Issue 2 2008Ginnie L. Abarbanell MD ABSTRACT Objectives., To review early surgical outcomes in a contemporary series of adults with congenital heart disease (CHD) undergoing cardiac operations at the University of Michigan, and to investigate possible preoperative and intraoperative risk factors for morbidity and mortality. Methods., A retrospective medical record review was performed for all patients ,18 years of age who underwent open heart operations by a pediatric cardiothoracic surgeon at the University of Michigan Congenital Heart Center between January 1, 1998 and December 31, 2004. Records from a cohort of pediatric patients ages 1,17 years were matched to a subset of the adult patients by surgical procedure and date of operation. Results., In total, 243 cardiac surgical operations were performed in 234 adult patients with CHD. Overall mortality was 4.7% (11/234). The incidence of major postoperative complications was 10% (23/234) with a 19% (45/23) minor complication rate. The most common postoperative complication was atrial arrhythmias in 10.8% (25/234). The presence of preoperative lung or liver disease, prolonged cardiopulmonary bypass and aortic cross clamp times, and postoperative elevated inotropic score and serum lactates were significant predictors of mortality in adults. There was no difference between the adult and pediatric cohorts in terms of mortality and morbidity. Conclusions., The postoperative course in adults following surgery for CHD is generally uncomplicated and early survival should be expected. Certain risk factors for increased mortality in this patient population may include preoperative presence of chronic lung or liver dysfunction, prolonged cardiopulmonary bypass and aortic cross-clamp times, and postoperative elevated inotropic score and serum lactate levels. [source] Transcatheter versus Surgical Closure of Secundum Atrial Septal Defect in Adults: Impact of Age at Intervention.CONGENITAL HEART DISEASE, Issue 3 2007A Concurrent Matched Comparative Study Abstract Objectives., To compare the short- and mid-term outcomes of surgical (SUR) vs. transcatheter closure of secundum atrial septal defect (ASD) using Amplatzer septal occluder (ASO) in adults with a very similar spectrum of the disease; and to identify predictors for the primary end point. Design., Single-center, concurrent comparative study. Surgically treated patients were randomly matched (2:1) by age, sex, date of procedure, ASD size, and hemodynamic profile. Setting., Tertiary referral center. Patients., One hundred sixty-two concurrent patients with ASD submitted to ASO (n = 54) or SUR closure (n = 108) according with their preferences. Main Outcome Measures., Primary end point was a composite index of major events including failure of the procedure, important bleeding, critical arrhythmias, serious infections, embolism, or any major cardiovascular intervention-related complication. Predictors of these major events were investigated. Results., Atrial septal defects were successfully closed in all patients, and there was no mortality. The primary event rate was 13.2% in ASO vs. 25.0% in SUR (P = .001). Multivariate analysis showed that higher rate of events was significantly associated with age >40 years; systemic/pulmonary output ratio <2.1; and systolic pulmonary arterial pressure >50 mm Hg; while in the ASO group the event rate was only associated with the ASD size (>15 cm2/m2; relative risk = 1.75, 95% confidence interval 1.01,8.8). There were no differences in the event-free survival curves in adults with ages <40 years. Conclusions., The efficacy for closure ASD was similar in both groups. The higher morbidity observed in SUR group was observed only in the patients submitted to the procedure with age >40 years. The length of hospital stay was shorter in the ASO group. Surgical closure is a safe and effective treatment, especially in young adults. There is certainly nothing wrong with continuing to do surgery in countries where the resources are limited. [source] Research Submission: Chronic Headache and Comorbibities: A Two-Phase, Population-Based, Cross-Sectional StudyHEADACHE, Issue 8 2010Ariovaldo Da Silva Jr MD Background., Studies using resources of a public family health program to estimate the prevalence of chronic daily headaches (CDH) are lacking. Objectives., To estimate the 1-year prevalence of CDH, as well as the presence of associated psychiatric and temporomandibular disorders (TMD) comorbidities, on the entire population of a city representative of the rural area of Brazil. Methods., This was a cross-sectional, population-based, 2-phase study. In the first phase, health agents interviewed all individuals older than 10 years, in a rural area of Brazil. In the second stage, all individuals who reported headaches on 4 or more days per week were then evaluated by a multidisciplinary team. CDH were classified according to the second edition of the International Classification of Headache Disorders (ICHD-2). Medication overuse headache was diagnosed, as per the ICHD-2, after detoxification trials. Psychiatric comorbidities and TMD were diagnosed based on the DSM-IV and on the Research Diagnostic Criteria for Temporomandibular Disorders criteria, respectively. Results., A total of 1631 subjects participated in the direct interviews. Of them, 57 (3.6%) had CDH. Chronic migraine was the most common of the CDH (21, 36.8%). Chronic tension-type headache (10, 17.5%), medication overuse headache (13, 22.8%) and probable medication overuse headache (10, 17.5%) were also common. Psychiatric disorders were observed in 38 (67.3%) of the CDH subjects. TMD were seen in 33 (58.1)% of them. Conclusions., The prevalence of CDH in the rural area of Brazil is similar to what has been reported in previous studies. A significant proportion of them have psychiatric comorbidities and/or TMD. In this sample, comorbidities were as frequent as reported in convenience samples from tertiary headache centers. (Headache 2010;50:1306-1312) [source] Long-Term, Open-Label Safety Study of Oral Almotriptan 12.5 mg for the Acute Treatment of Migraine in AdolescentsHEADACHE, Issue 5 2010Frank Berenson MD (Headache 2010;50:795-807) Objectives., This study evaluated the long-term safety of oral almotriptan 12.5 mg for the treatment of multiple migraine episodes in adolescents over a 12-month period. Efficacy outcomes were assessed as a secondary objective. Methods., Adolescent migraineurs aged 12-17 years were enrolled in this 12-month, open-label study (Study ID CR002827). Patients were instructed to record their assessments on paper headache records whenever they experienced a migraine headache that they treated with study medication. Safety was assessed descriptively and assessments included adverse event (AE) recording, change in laboratory values, vital signs, and electrocardiogram parameters. Efficacy outcomes were assessed descriptively and outcomes included rates for 2- and 24-hour pain relief and sustained pain relief, 2- and 24-hour pain-free and sustained pain-free, and presence of migraine-associated symptoms of photophobia, phonophobia, nausea and vomiting. Results., Overall, 67.1% of patients reported ,1 AE over the course of the trial, 7.6% had an AE judged by the study investigator to be related to treatment with almotriptan, 2.4% discontinued because of an AE, and 1.9% reported serious AEs. The most commonly reported treatment-related AEs (occurring in ,1% of patients) were nausea (1.4%) and somnolence (1.4%). Pain relief responses for treated migraines of moderate or severe intensity at baseline were 61.7% and 68.6%, at 2 and 24 hours, respectively; the sustained pain relief rate was 55.5%. Pain-free responses were reported for 40.5% of all treated migraines at 2 hours and 65.9% of treated migraines at 24 hours; the sustained pain-free rate was 38.4%. The proportion of migraines that achieved the pain relief, sustained pain relief, pain-free and sustained pain-free endpoints were similar in the 12- to 14-year and 15- to 17-year age groups. Treating with almotriptan 12.5 mg when headache pain was mild was associated with higher rates of pain relief and pain-free at 2 and 24 hours, and sustained pain relief and sustained pain-free, compared with treatment initiated when pain was severe. Conclusions., Almotriptan 12.5 mg was well tolerated in this adolescent population over a 12-month period. No unexpected safety or tolerability concerns were revealed over the course of this study. The results are consistent with almotriptan 12.5 mg being effective for the acute treatment of pain and symptoms associated with migraine in both younger and older adolescents. [source] Childhood Maltreatment and Migraine (Part II).HEADACHE, Issue 1 2010Emotional Abuse as a Risk Factor for Headache Chronification (Headache 2010;50:32-41) Objectives., To assess in a headache clinic population the relationship of childhood abuse and neglect with migraine characteristics, including type, frequency, disability, allodynia, and age of migraine onset. Background., Childhood maltreatment is highly prevalent and has been associated with recurrent headache. Maltreatment is associated with many of the same risk factors for migraine chronification, including depression and anxiety, female sex, substance abuse, and obesity. Methods., Electronic surveys were completed by patients seeking treatment in headache clinics at 11 centers across the United States and Canada. Physician-determined data for all participants included the primary headache diagnoses based on the International Classification of Headache Disorders-2 criteria, average monthly headache frequency, whether headaches transformed from episodic to chronic, and if headaches were continuous. Analysis includes all persons with migraine with aura, and migraine without aura. Questionnaire collected information on demographics, social history, age at onset of headaches, migraine-associated allodynic symptoms, headache-related disability (The Headache Impact Test-6), current depression (The Patient Health Questionnaire-9), and current anxiety (The Beck Anxiety Inventory). History and severity of childhood (<18 years) abuse (sexual, emotional, and physical) and neglect (emotional and physical) was gathered using the Childhood Trauma Questionnaire. Results., A total of 1348 migraineurs (88% women) were included (mean age 41 years). Diagnosis of migraine with aura was recorded in 40% and chronic headache (,15 days/month) was reported by 34%. Transformation from episodic to chronic was reported by 26%. Prevalence of current depression was 28% and anxiety was 56%. Childhood maltreatment was reported as follows: physical abuse 21%, sexual abuse 25%, emotional abuse 38%, physical neglect 22%, and emotional neglect 38%. In univariate analyses, physical abuse and emotional abuse and neglect were significantly associated with chronic migraine and transformed migraine. Emotional abuse was also associated with continuous daily headache, severe headache-related disability, and migraine-associated allodynia. After adjusting for sociodemographic factors and current depression and anxiety, there remained an association between emotional abuse in childhood and both chronic (odds ratio [OR] = 1.77, 95% confidence intervals [CI]: 1.19-2.62) and transformed migraine (OR = 1.89, 95% CI: 1.25-2.85). Childhood emotional abuse was also associated with younger median age of headache onset (16 years vs 19 years, P = .0002). Conclusion., Our findings suggest that physical abuse, emotional abuse, and emotional neglect may be risk factors for development of chronic headache, including transformed migraine. The association of maltreatment and headache frequency appears to be independent of depression and anxiety, which are related to both childhood abuse and chronic daily headache. The finding that emotional abuse was associated with an earlier age of migraine onset may have implications for the role of stress responses in migraine pathophysiology. [source] A Study to Evaluate the Feasibility of an Aerobic Exercise Program in Patients With MigraineHEADACHE, Issue 4 2009Emma Varkey RPT Objectives., The aim of this study was to develop and evaluate an exercise program to improve maximum oxygen uptake (VO2 max) in untrained patients with migraine without making their migraines worse. Patients and methods., Twenty-six patients were studied at a headache clinic in Sweden. The exercise program, based on indoor cycling, was performed 3 times per week during 12 weeks. VO2 max, migraine status, side effects, and quality of life were evaluated. Results., VO2 max increased from 32.9 mL/kg/minute to 36.2 mL/kg/minute (P = .044). Quality of life increased and significant improvements in migraine status (attack frequency, symptom intensity, and intake of medicine) were seen. During the 12 weeks of exercise, on one occasion one patient had a migraine attack, which started immediately after training. No other side effects were reported. Conclusions., The evaluated exercise program was well tolerated by the patients and improved their VO2 max with no deterioration of migraine status. [source] Development and Construct Validation of the Pharmacists' Care of Migraineurs ScaleHEADACHE, Issue 1 2009Monica L. Skomo PharmD Objectives., To develop the pharmacists' care of migraineurs scale (PCMS) and to evaluate its psychometric properties. Background., Migraine is often managed suboptimally in primary care. Migraineurs frequently come into contact with community pharmacists, who have the opportunity to make a positive impact on migraineur treatment outcomes. A valid and reliable tool that measures and documents the care provided by pharmacists to migraineurs is critical to the development and evaluation of educational programs and interventions. Methods., Relevant domains of pharmacist care and their respective composite items (behaviors) were identified through an extensive literature search and the use of 2 pharmacist and 2 migraineur focus groups sessions. The resultant 45 PCMS items composed a survey questionnaire mailed to a nationwide random sample of 6000 pharmacists. Data were subjected to an exploratory principal axis factoring procedure to discern the factor structure, and as such describe the latent domains composing the pharmacist caring behaviors constructs. Results., A total of 580 usable responses were returned, with an additional 60 returned as undeliverable, thus yielding a response rate of 9.7%. Exploratory factor analysis using principal axis factoring yielded 9 factors. However, upon examining the scree plot, communalities, and factor loadings, a reanalysis forcing a 7-factor solution yielded a more interpretable and plausible factor structure. The 7-factor solution included the following domains: (1) empathy; (2) prospective drug utilization review for newly diagnosed migraineurs; (3) medication counseling; (4) nonpharmacologic treatment plan; (5) headache sufferer triage; (6) dissemination of public health information; (7) maintenance of knowledge on migraine. Following the application of scale purification procedures, the final instrument is composed of 41 items and demonstrated a Cronbach's alpha reliability of 0.947. Cronbach's alpha reliabilities for the 7 domains ranged from 0.67 to 0.91, indicative of good to excellent internal consistency reliabilities for all the domains. Conclusions., The PCMS demonstrated very good construct validity and reliability. While additional validity testing is warranted, the PCMS should allow for benchmarking in the evaluation of interventions designed to improve pharmacists' care to migraineurs and for identifying correlates to effective community pharmacist migraineur care. [source] Migraine Disability Awareness Campaign in Asia: Migraine Assessment for ProphylaxisHEADACHE, Issue 9 2008Shuu-Jiun Wang MD Objectives., This study aimed to survey the headache diagnoses and consequences among outpatients attending neurological services in 8 Asian countries. Methods., This survey recruited patients who consulted neurologists for the first time with the chief complaint of headache. Patients suffering from headaches for 15 or more days per month were excluded. Patients answered a self-administered questionnaire, and their physicians independently completed a separate questionnaire. In this study, the migraine diagnosis given by the neurologists was used for analysis. The headache symptoms collected in the physician questionnaire were based on the diagnostic criteria of migraine proposed by the International Classification of Headache Disorders, second edition (ICHD-2). Results., A total of 2782 patients (72% females; mean age 38.1 ± 15.1 years) finished the study. Of them, 66.6% of patients were diagnosed by the neurologists to have migraine, ranging from 50.9% to 85.8% across different countries. Taken as a group, 41.4% of those patients diagnosed with migraine had not been previously diagnosed to have migraine prior to this consultation. On average, patients with migraine had 4.9 severe headaches per month with 65% of patients missing school, work, or household chores. Most (87.5%) patients with migraine took medications for acute treatment. Thirty-six percent of the patients had at least one emergency room consultation within one year. Only 29.2% were on prophylactic medications. Neurologists recommended pharmacological prophylaxis in 68.2% of patients not on preventive treatment. In comparison, migraine prevalence was the highest with ICHD-2 "any migraine" (ie, migraine with or without migraine and probable migraine) (73.3%) followed by neurologist-diagnosed migraine (66.6%) and ICHD-2 "strict migraine" (ie, migraine with or without aura only) (51.3%). About 88.6% patients with neurologist-diagnosed migraine fulfilled ICHD-2 any migraine but only 67.1% fulfilled the criteria of ICHD-2 strict migraine. Conclusions., Migraine is the most common headache diagnosis in neurological services in Asia. The prevalence of migraine was higher in countries with higher referral rates of patients to neurological services. Migraine remains under-diagnosed and under-treated in this region even though a high disability was found in patients with migraine. Probable migraine was adopted into the migraine diagnostic spectrum by neurologists in this study. [source] Common CX3CR1 Alleles Are Associated With a Reduced Risk of HeadachesHEADACHE, Issue 7 2008Christophe Combadière PhD Objectives., The aim of this study was to investigate the role of the chemokine receptor CX3CR1 in headaches and migraine. Methods., Distribution of 2 polymorphisms of the chemokine receptor CX3CR1 (V249I and T280M) was determined in a population-based sample of 1179 elderly individuals. Results., Heterozygotes for both CX3CR1 polymorphisms had a reduced risk of recurrent headaches, with an odds ratio (OR) of 0.64 (95% confidence interval [CI] = 0.46-0.90) for the I249 allele and 0.55 (95% CI = 0.38-0.81) for the M280 allele. Haplotype analysis showed that carriers of the rarer CX3CR1 I249-M280 haplotype had a reduced risk of recurrent headaches, with an OR of 0.57 (95% CI = 0.41-0.80, P = .001). This association was seen for both nonmigraine headaches (OR = 0.47, 95% CI = 0.28-0.79, P = .004) and migraine (OR = 0.65, 95% CI = 0.43-0.98, P = .041). Conclusions., These results need to be replicated but suggest that the chemokine receptor CX3CR1 may play a role in recurrent headaches. [source] Effects of Distraction Versus Spatial Discrimination on Laser-Evoked Potentials in MigraineHEADACHE, Issue 3 2008Marina De Tommaso MD Objectives., To evaluate whether migraine patients exhibit less inhibition to painful stimuli when distracted from pain as compared to healthy subjects, testing the spatial discrimination of painful stimuli, the performance during the mental arithmetic task used to contrast the discrimination performance and the behavior of N1 and N2-P2 laser-evoked potentials (LEPs) amplitudes during spatial discrimination and during distraction. Methods., Eight migraine patients and 8 healthy controls were examined. During repetitive series of painful laser stimulation of the hand, they had to (1) perform a spatial discrimination task, contrasted by (2) a mental arithmetic task that served as distraction. Results., Patients made 50% to 100% more mistakes than controls in the spatial discrimination task (P < .001) as well as during mental arithmetic (P < .05). Whereas healthy subjects showed a marked decrease of the LEP vertex potential amplitudes during distraction compared to the discrimination task, no such attenuation of LEPs was seen in migraine patients (group × task interaction, P < .05). N1 amplitude exhibited a left-hemisphere dominance in both groups, significantly smaller amplitude in migraine patients, but no significant task modulation. Conclusion., Migraine patients exhibited reduced inhibition by attentional modulation of pain processing, accompanied by impaired spatial discrimination of painful stimuli. [source] Characteristics of Migraine Attacks and Responses to Almotriptan Treatment: A Comparison of Menstrually Related and Nonmenstrually Related MigrainesHEADACHE, Issue 2 2008Merle L. Diamond MD Objectives., To compare the clinical characteristics of menstrually related migraines (MRMs) and nonmenstrually related migraines (nonMRMs) and to investigate the efficacy of almotriptan in the treatment of these migraine subtypes. Design/Methods., These are post hoc analyses of data from the AXERT® Early miGraine Intervention Study (AEGIS), a multicenter, double-blind, parallel-group trial that evaluated adults with IHS-defined migraine with and without aura. Patients were randomized 1 : 1 to treat 3 consecutive headaches with almotriptan 12.5 mg or matching placebo at the first sign of headache typical of their usual migraine, at any level of pain intensity but within 1 hour of onset. MRMs were defined as those occurring ±2 days of the first day of menstrual flow. Post hoc analyses to describe headache characteristics pooled all migraine attacks experienced by patients who reported ,1 menses during the study regardless of assigned treatment group. The post hoc efficacy analyses included outcomes of almotriptan treatment compared with placebo treatment for all migraines in patients with a menstrual record. Results., Of the 275 women in the AEGIS intent-to-treat population, 190 (69.1%; 97 almotriptan, 93 placebo; aged 18-54 years) reported ,1 menses during the trial. Of the 506 migraines reported by these patients, 95 (18.8%) occurred ±2 days of the first day of menstrual flow and were defined as MRM. Aura was associated with 11.7% of MRM and 15.0% of nonMRM. Allodynia-associated symptoms were present with 62.8% of MRM and 57.0% of nonMRM. Prior to treatment, 19.1% of MRM were associated with normal functional ability, 68.1% with disturbed functional ability, and 12.8% required bed rest compared with 18.9%, 68.8%, and 12.3%, respectively, of nonMRM. Pretreatment pain intensity was mild in 40.0%, moderate in 47.4%, and severe in 12.6% of MRM compared with 43.6%, 47.2%, and 9.2%, respectively, of nonMRM. Almotriptan treatment efficacy outcomes for MRM vs nonMRM, respectively, were: 2-hour pain relief, 77.4% vs 68.3%; 2-hour pain free, 35.4% vs 35.9%; and sustained pain free, 22.9% vs 23.8%. Almotriptan was similarly effective in relieving migraine-associated symptoms and improving functional disability associated with both MRM and nonMRM. Conclusions., Prior to treatment, the presence of migraine-associated characteristics including aura, allodynia-associated symptoms, photophobia, phonophobia, and nausea were similar for both MRM and nonMRM attacks. The pretreatment levels of pain intensity and functional disability were likewise similar across the migraine subtypes. Almotriptan was equally effective in the treatment of both MRM and nonMRM attacks and was associated with an adverse event profile that was similar to placebo treatment. [source] Behavioral Sleep Modification May Revert Transformed Migraine to Episodic MigraineHEADACHE, Issue 8 2007Anne H. Calhoun MD Background.,Sleep problems have been linked with headaches for more than a century, but whether the headaches are the cause or the result of the disrupted sleep is unknown. Objectives.,We previously reported that nonrestorative sleep and poor sleep habits are almost universal in a referral population of women with transformed migraine (TM). Since cognitive behavioral therapy is effective in improving sleep quality in individuals with poor sleep hygiene, we designed a randomized, placebo-controlled study to assess the impact of such treatment on TM. We hypothesized that behavioral sleep modification (BSM) would be associated with improvement in headache frequency and intensity and with reversion to episodic migraine. Methods.,Subjects were 43 women with TM referred to an academic headache center. After obtaining informed consent, patients were randomized to receive either behavioral sleep instructions or placebo behavioral instructions in addition to usual medical care. Subjects recorded headaches in standardized diaries. The first postintervention visit was scheduled at 6 weeks. At that visit, the blind was broken and all subjects received BSM instructions. A final visit was scheduled 6 weeks later. Results.,Compared to the placebo behavioral group, the BSM group reported statistically significant reduction in headache frequency [F (1, 33 = 12.42, P=.001)] and headache intensity [F(1, 33 = 14.39, P= .01)]. They were more likely to revert to episodic migraine ,2 (2, n = 43) = 7.06, P= .029. No member of the control group reverted to episodic migraine by the first postintervention visit. By the final visit, 48.5% of those who had received BSM instructions had reverted to episodic migraine. Conclusions.,In this pilot study of women with TM, we found that a targeted behavioral sleep invention was associated with improvement in headache frequency, headache index, and with reversion to episodic migraine. [source] Is Headache Related to Asthma, Hay Fever, and Chronic Bronchitis?HEADACHE, Issue 2 2007The Head-HUNT Study Objectives.,To examine the relationship between migraine and nonmigrainous headache and asthma, hay fever, and chronic bronchitis in a large cross-sectional population-based study. Background.,Associations between prevalence of migraine and asthma or allergy have been demonstrated in clinic-based and epidemiologic studies whereas studies on chronic bronchitis are scarce. Methods.,A total of 51,383 subjects completed a headache questionnaire and constituted the "Head-HUNT" Study. Of these 50,401 (98.1%) answered the questions about asthma and chronic bronchitis, and 47,029 (91.5%) answered the question about hay fever. Associations were assessed in multivariate analyses, estimating prevalence odds ratios (ORs) with 95% confidence intervals (CI). Results.,Both migraine and nonmigrainous headache were approximately 1.5 times more likely among those with current asthma, asthma related symptoms, hay fever, and chronic bronchitis than those without. The association increased with increasing headache frequency. Conclusions.,This large questionnaire-based study confirms that migraine and other headaches are associated with respiratory and allergic disorders. The magnitude of the association between headache and asthma, hay fever, and chronic bronchitis tended to be in the same order. Headache frequency seems to have a greater impact on the association with respiratory or allergic conditions than headache diagnoses. Whether it is a causal relationship is uncertain, but the results underline the importance of considering comorbid disorders among patients with frequent headache. [source] Endothelial Function in Patients With Migraine During the Interictal PeriodHEADACHE, Issue 1 2007Federico A. Silva MD Objectives.,The aim of this study is to evaluate endothelial function in migraineur subjects during the asymptomatic period. Background.,Migraine has been proposed as a risk factor for cerebrovascular events. The underlying mechanisms that relate these 2 pathologies are unknown. Nitric oxide (NO) has been proposed as the final causative molecule of migraine. Increased NO metabolites concentrations have been reported in migraineur subjects during acute migraine attacks, but there is no evidence indicating alterations in endothelial NO release during the symptom free period in theses subjects. Design and Methods.,Fifty migraineur subjects and 25 healthy subjects matched by gender and age were included. Every subject underwent a complete examination that included medical history, physical examination, resting electrocardiogram, forearm flow-mediated vasodilation (FMD), blood determinations of fasting nitrates and nitrites (NO2,+ NO3,), glucose, lipid profile, creatinine, C-reactive protein, and blood cell count. Results.,No differences in FMD or NO2,+ NO3, were detected among groups. The only difference between migraineurs and control subjects was a higher mean blood pressure 92.1 (8.8) mmHg versus 86.7 (8.2) mmHg P= .01. Conclusion.,The endothelial function is not altered during the interictal period in migraineur subjects. [source] Assessment of Adverse Events Associated With Triptans,Methods of Assessment Influence the ResultsHEADACHE, Issue 10 2004Fred D. Sheftell MD Background.,A recent study conducted in triptan-naïve migraine patients showed that tolerability was the second most important attribute of an acute treatment. However, the proportion of patients reporting side effects after any acute treatment may vary with regard to the method of assessment. Objectives.,To contrast two methods of assessing adverse events (prompted and unprompted) in those with headache using triptans. Methods.,This study was conducted in two sites, a headache center in the United States, and a neurology office focusing on headache in Italy. We prospectively surveyed 415 adults with headache, who had been using the same triptan for at least 3 months. Participants were asked about their headache and treatment history. Subjects then completed a standardized questionnaire, assessing adverse events in two different ways. First, subjects were asked if they had any adverse events when using the triptan. After returning the first part of the questionnaire, subjects received a second form, where 49 possible adverse events were listed. We contrasted and correlated both sets of answers. Results.,Most patients (U.S. = 74.9%, Italy = 65.5%) reported no side effects in the unprompted questionnaire. However, most of them (U.S. = 62.9%, Italy = 54.1%) reported at least one side effect in the prompted questionnaire. Most patients that reported side effects in the unprompted questionnaire said they had just one adverse event, while most reported two or more side effects in the prompted questionnaire. Both in the unprompted and in the prompted questionnaires, most side effects were rated as mild or moderate. Interestingly, 31 (7.5%) subjects (pooling data from both sites together) graded their adverse events as severe in the prompted questionnaire, but had not self-reported them. Conclusions.,(1) When assessing adverse events, the method of data collection may dramatically influence the results. (2) From those subjects who did not self-report adverse events after using a triptan, most of them will report positively if presented with a list of side effects. [source] Validity and Reliability of the Turkish Migraine Disability Assessment (MIDAS) QuestionnaireHEADACHE, Issue 8 2004Mustafa Erta Objectives.,The aim of this study is to assess the comprehensibility, internal consistency, patient-physician reliability, test-retest reliability, and validity of Turkish version of Migraine Disability Assessment (MIDAS) questionnaire in patients with headache. Background.,MIDAS questionnaire has been developed by Stewart et al and shown to be reliable and valid to determine the degree of disability caused by migraine. Design and Methods.,This study was designed as a national multicenter study to demonstrate the reliability and validity of Turkish version of MIDAS questionnaire. Patients applying to 17 Neurology Clinics in Turkey were evaluated at the baseline (visit 1), week 4 (visit 2), and week 12 (visit 3) visits in terms of disease severity and comprehensibility, internal consistency, test-retest reliability, and validity of MIDAS. Since the severity of the disease has been found to change significantly at visit 2 compared to visit 1, test-retest reliability was assessed using the MIDAS scores of a subgroup of patients whose disease severity remained unchanged (up to ±3 days difference in the number of days with headache between visits 1 and 2). Results.,A total of 306 patients (86.2% female, mean age: 35.0 ± 9.8 years) were enrolled into the study. A total of 65.7%, 77.5%, 82.0% of patients reported that "they had fully understood the MIDAS questionnaire" in visits 1, 2, and 3, respectively. A highly positive correlation was found between physician and patient and the applied total MIDAS scores in all three visits (Spearman correlation coefficients were R= 0.87, 0.83, and 0.90, respectively, P < .001). Internal consistency of MIDAS was assessed using Cronbach's , and was found at acceptable (>0.7) or excellent (>0.8) levels in both patient and physician applied MIDAS scores, respectively. Total MIDAS score showed good test-retest reliability (R= 0.68). Both the number of days with headache and the total MIDAS scores were positively correlated at all visits with correlation coefficients between 0.47 and 0.63. There was also a moderate degree of correlation (R= 0.54) between the total MIDAS score at week 12 and the number of days with headache at visit 2 + visit 3, which quantify headache-related disability over a 3-month period similar to MIDAS questionnaire. Conclusion.,These findings demonstrated that the Turkish translation is equivalent to the English version of MIDAS in terms of internal consistency, test-retest reliability, and validity. Physicians can reliably use the Turkish translation of the MIDAS questionnaire in defining the severity of illness and its treatment strategy when applied as a self-administered report by migraine patients themselves. [source] The Effect of Weather on HeadacheHEADACHE, Issue 6 2004Patricia B. Prince MD Objectives.,To assess headache patients' beliefs about how strongly weather affects their headaches; To objectively investigate the influence of multiple weather variables on headache. Design and Methods.,Our sample consisted of 77 migraineurs seen in a headache clinic, who provided headache calendars for a period ranging from 2 to 24 months. Our study was divided into two phases. First, each patient was given a questionnaire assessing their beliefs about how strongly (if so) weather affected their headaches. Second, weather data were collected from the National Weather Service, from three reporting stations central to the residences of the study participants. Analysis was performed on 43 variables to generate three meteorological factors. Linear regression was used to assess the relationship between headache and these three factors. Factor 1 represents a function of absolute temperature and humidity. Factor 2 represents a changing weather pattern. Factor 3 represents barometric pressure. Results.,Of the 77 subjects in the study, 39 (50.6%), were found to be sensitive to weather, but 48 (62.3%) thought they were sensitive to weather conditions (P < 0.05). Thirty (38.9%) were sensitive to one weather factor and 9 (11.7%) to two factors. Twenty-six (33.7%) were sensitive to factor 1; 11 (14.3%) to factor 2; 10 (12.9%) to factor 3. Conclusions.,Our study supports the influence of weather variables on headache. We showed that patients are susceptible to multiple weather variables and that more patients thought weather was a trigger than was the case. [source] Use of the Migraine Disability Assessment Questionnaire in Children and Adolescents With Headache: An Italian Pilot StudyHEADACHE, Issue 7 2003D. D'Amico MD Objectives.,To determine the suitability of the Migraine Disability Assessment (MIDAS) Questionnaire for assessing disability in children and adolescents with headache and to obtain preliminary information about disability in different primary headaches. Background.,During the last decade, researchers have begun to employ standardized methodologies to investigate the global impact of primary headaches. Disease-specific instruments have been developed to measure headache-related disability. The MIDAS Questionnaire, which is the most extensively studied of these instruments, was designed to assess the overall impact of headaches over the 3 months before compilation. The MIDAS Questionnaire is an optimal tool to assess headache-related disability in adults. Methods.,Ninety-five patients aged 7 to 17 years with tension-type headache, migraine, or both completed the validated Italian form of the MIDAS questionnaire on 2 occasions. Test-retest reliability was assessed by the Spearman rank correlation test. The Cronbach , assessed internal consistency. The patients answered questions about the adequacy of the questionnaire. Results.,The Cronbach , was .8. Correlation coefficients were generally high for the overall MIDAS score and for the items investigating disability in school and in family/leisure activities; they were lower for the items about housework. Most patients thought that the MIDAS Questionnaire was useful (98.9%) and that it captured the impact of their headaches (58.9%); 41% thought that questions about disability in housework were useless, 44.2% suggested adding questions regarding inability to do homework. All primary headaches had a considerable impact on daily activities, but patients with migraine tended to have lower headache frequencies and lower total disability time; those with tension-type headache suffered more days in which activities, although performed, were substantially impaired. Conclusions.,The MIDAS Questionnaire is useful for assessing disability in children and adolescents with different primary headaches. Minimal changes in the phrasing and content of the items would be sufficient to render the MIDAS specific for the younger population with headache. [source] Migraine Headache Recurrence: Relationship to Clinical, Pharmacological, and Pharmacokinetic Properties of TriptansHEADACHE, Issue 4 2003Gilles Géraud MD Background and Objectives.,Triptan use is associated with headache recurrence, and this has been cited as an important reason for patient dissatisfaction with the treatment. The mechanism by which recurrence occurs is not clear, and the incidence of recurrence varies with the triptan used. In order to explore the pharmacological and physiological interaction of triptans and migraine headache recurrence further, some specific clinical, pharmacological, and pharmacokinetic factors that might influence migraine recurrence were evaluated in a review of the major efficacy data for the drugs in the triptan class. These factors were 5-HT1B and 5-HT1D receptor activities, the pharmacokinetic elimination half-life of each triptan, and the clinical efficacy of each compound, determined by the proportion of patients with headache relief and the therapeutic gain over placebo. Methods.,Clinical data were derived from 31 triptan, placebo-controlled, major efficacy studies used in a previous meta-analysis. The mean recurrence rate, mean headache response, and therapeutic gain were calculated using the results from the individual clinical studies. Mean headache response and therapeutic gain were calculated at the time point used to define recurrence in each study. Data for binding affinity and potency were taken from a direct-comparison in vitro pharmacology study, and the elimination half-life quoted in the data sheet for each triptan was used. Rank correlation with recurrence rate was performed for each of the test parameters. Results.,Mean headache recurrence rates ranged from 17% for frovatriptan 2.5 mg to 40% for rizatriptan. Elimination half-life and recurrence were inversely correlated (r = ,1.0, P = .0016). There was also a significant inverse correlation between 5-HT1B receptor potency and recurrence (r = ,0.68, P = .034), but 5-HT1D receptor potency was not correlated with recurrence (r = ,0.20, P = .54). In addition, the binding affinities for the 5-HT1B and 5-HT1D receptors were not correlated to headache recurrence. Importantly, it also was demonstrated that initial clinical efficacy was not correlated to headache recurrence. The correlation coefficient for headache response was 0.18 (P = .53) and for therapeutic gain, ,0.11 (P = .71). Conclusion.,The incidence of migraine headache recurrence varies between drugs in the triptan class. Migraine recurrence does not appear to be related to initial clinical efficacy, but is influenced by the pharmacological and pharmacokinetic properties of the individual triptans. The triptans with longer half-lives and greater 5-HT1B receptor potency had the lowest rates of headache recurrence. [source] Application of the 1988 International Headache Society Diagnostic Criteria in Nine Italian Headache Centers using a Computerized Structured RecordHEADACHE, Issue 10 2002Virgilio Gallai MD Background.,The actual application of the current International Headache Society (IHS) diagnostic criteria in clinical practice has not been investigated thoroughly. Objectives.,To develop a computerized, structured, medical record based exclusively on the IHS classification system. Design and Method.,We tested the computerized structured record by entering and analyzing data reported on the case sheets of 500 consecutive patients attending nine headache centers in Italy. All clinical diagnoses in the study were made according to current IHS criteria. The rate of concordance between the diagnosis provided by the computerized structured record and that reported by clinicians on the case sheets was calculated, and reasons for any discrepancies between the two diagnoses were analyzed. Results.,Concordance between the two diagnoses was found in 345 of 500 cases examined (69%). In the remaining 155 cases, diagnoses reached with the computerized structured record and case sheets were impossible or discordant with respect to the diagnoses made by the clinician. In 144 of these cases (28.8%), this was due to missing information or errors in the diagnosis recorded by the clinicians on the patient case sheet. In particular, the diagnosis could not be reached using the computerized structured record in 105 cases (20.6%) because of a lack of one or more data needed in formulating a correct diagnosis according to the IHS operational criteria for one of the primary headache disorders. In the remaining 41 cases some data were missing, but the data available were sufficient to reach a diagnosis according to the IHS criteria. Moreover, the diagnoses reached using the computerized structured record were not in agreement with those made by the clinicians in another 39 cases (7.9%) due to an incorrect interpretation by the clinicians of the data reported on the patients' case sheets. In only 2.2% of the cases (n = 11) misdiagnoses were due to errors of the program that were promptly corrected. Conclusions.,The present study suggests that incorrect application of IHS criteria for the diagnosis of primary headache may occur in as many as one third of patients attending headache centers and that use of a computerized structured record based exclusively on current IHS criteria may overcome this deficiency. [source] Almotriptan Reduces the Incidence of Migraine-Associated Symptoms: A Pooled AnalysisHEADACHE, Issue 2002Roger Cady MD Objectives.,Evaluate the reduction in migraine-associated symptoms after administration of a single oral dose of almotriptan. Methods.,This pooled analysis (N=1773) used data from three randomized, placebo-controlled, phase III trials (studies A, B, and C) to determine the incidence of migraine-associated symptoms (defined as nausea, vomiting, photophobia, and phonophobia) 2 hours after a single oral dose of study medication (almotriptan, sumatriptan, or placebo). Outcome data was extracted from studies A and B for placebo and the almotriptan 6.25-mg and 12.5-mg groups, and from study C for placebo, almotriptan 12.5-mg, and sumatriptan 100-mg groups. Results.,The incidence of nausea, photophobia, and phonophobia at 2 hours after dosing with study medication was significantly reduced (all P < .05) with almotriptan 6.25 mg or 12.5 mg compared with placebo. The percentage of patients with vomiting was lower with both doses of almotriptan in studies A and B compared with placebo, although differences were significant only for the 6.25-mg dose in study A (P < .001). For study C, the incidence of nausea, vomiting, photophobia, and phonophobia was similar for almotriptan and sumatriptan and lower than with placebo at 2 hours after dosing. Significant reductions (all P < .05) versus placebo were observed in the incidence of vomiting and phonophobia with almotriptan 12.5 mg, and photophobia and phonophobia with sumatriptan 100 mg. Conclusion.,Almotriptan provides relief from migraine-associated symptoms of nausea, vomiting, photophobia, and phonophobia, and thus represents an attractive treatment option for a wide spectrum of migraine symptomatology. [source] Almotriptan Increases Pain-Free Status in Patients With Acute Migraine Treated in Placebo-Controlled Clinical TrialsHEADACHE, Issue 2002FRCP(C), Ninan T. Mathew MD Objectives.,Evaluate the efficacy of a single oral dose of almotriptan in achieving pain-free status during treatment of acute migraine attacks. Methods.,This pooled analysis (N=1321) used data from two randomized, placebo-controlled, phase III trials (studies A and B) to determine the proportion of patients with migraine achieving pain-free status 2 hours after a single oral dose of study medication (almotriptan or placebo). Pain was assessed using a 4-point integer scale (0=no headache, 3=severe headache), and recorded in a patient self-assessment booklet. Results.,The proportion of patients pain-free at 2 hours after study medication was significantly greater with almotriptan 6.25 mg (both studies P,.002) and almotriptan 12.5 mg (both studies P,.001) than with placebo. In study A, 11.6% of patients taking almotriptan 12.5 mg versus 2.5% of patients receiving placebo were pain-free at 1 hour (P=.016). At 1.5 hours, 26.8% of patients taking almotriptan 12.5 mg versus 8.8% receiving placebo (P=.001) were pain-free, and at 2 hours, 38.4% on almotriptan versus 11.3% on placebo were pain-free (P<.001). In study B, 23.8% of patients taking almotriptan 12.5 mg were free from pain at 1.5 hours versus 10.2% receiving placebo (P<.001). At 2 hours, 39.2% taking almotriptan 12.5 mg versus 15.3% receiving placebo were pain-free (P<.001). Increases in pain-free status with almotriptan generally occurred in a dose-dependent manner. Conclusion.,Compared with placebo, almotriptan 12.5 mg significantly increases the proportion of patients who are pain-free by as early as 1 hour, and consistently by 1.5 hours, after a single dose. [source] Prevalence of Migraine in Croatia: A Population-Based SurveyHEADACHE, Issue 8 2001Robert Zivadinov MD Objectives.,The aim of the present study was to estimate the prevalence of migraine among Croatian adults. This is the first epidemiological study of migraine in Croatia in which the operational diagnostic criteria of the International Headache Society have been applied. Methods.,The study population consisted of all residents (aged 15 to 65 years) of Bakar, County of The Coast and Gorski Kotar, Croatia. A population-based survey was undertaken using a "face-to-face, door-to-door" interview method. The participation rate was 73.3%. All participants were screened for headache history according to the International Headache Society criteria. Headache screen positive responders (65.7%) were interviewed by trained medical students with a structured detailed interview focused on migraine. Results.,A total of 720 lifetime migraineurs were identified. The lifetime prevalence of migraine was 22.9% (95% confidence interval, 20.9 to 25.1) in women, 14.8% (95% confidence interval, 13.1 to 16.8) in men, and 19% (95% confidence interval, 17.6 to 20.5) in both sexes. The highest lifetime prevalence of migraine was in women in the age group 40 to 49 years (38.1%). Among 636 active migraineurs, 399 (62.7%) were women and 237 (37.3%) were men; 55.8% had migraine without aura, 35.2% migraine with aura, and 6.9% migraine both with and without aura. The 1-year prevalence of migraine, migraine without aura, migraine with aura, and migraine both with and without aura in women was 18%, 11.3%, 8.6%, and 2.2%, respectively. In men, the 1-year prevalence of migraine, migraine without aura, migraine with aura, and migraine both with and without aura was 12.3%, 7.3%, 3%, and 0.7%, respectively. Conclusions.,The prevalence of migraine in this Croatian population showed rates quite similar to those reported in neighboring countries, such as Italy and France. Further studies are needed to estimate the prevalence rates of migraine in the total Croatian population. [source] Visual Cortex Excitability in Migraine With and Without AuraHEADACHE, Issue 6 2001Wim M. Mulleners MD Objectives.,Previous research using transcranial magnetic stimulation has produced equivocal findings concerning thresholds for the generation of visual phosphenes in migraine with aura. These studies were methodologically varied and did not systematically address cortical excitability in migraine without aura. We therefore studied magnetophosphene thresholds in both migraine with aura and migraine without aura compared with headache-free controls. Methods.,Sixteen subjects with migraine with aura and 12 subjects with migraine without aura were studied and compared with 16 sex- and age-matched controls. Using a standardized transcranial magnetic stimulation protocol of the occipital cortex, we assessed the threshold stimulation intensity at which subjects just perceived phosphenes via a method of alternating course and fine-tuning of stimulator output. Results.,There were no significant differences across groups in the proportion of subjects seeing phosphenes. However, the mean threshold at which phosphenes were reported was significantly lower in both migraine groups (migraine with aura=47%, migraine without aura=46%) than in controls (66%). Moreover, there was no significant correlation between individual phosphene threshold and the time interval to the closest migraine attack. Conclusion.,Our findings confirm that the occipital cortex is hyperexcitable in the migraine interictum, both in migraine with and without aura. [source] Opiate Use to Control Bowel Motility May Induce Chronic Daily Headache in Patients With MigraineHEADACHE, Issue 3 2001S.M. Wilkinson MD Objectives.,To investigate whether opiate overuse might cause chronic daily headache in those with migraine, we studied patients who were taking codeine (or other opiates) for control of bowel motility after colectomy for ulcerative colitis. Background.,Analgesic overuse is considered by many to be one factor which can result in the transformation of migraine into a chronic daily headache pattern. Most of the evidence for this comes from patients with migraine who are taking increasing amounts of analgesia for headache. Many of these patients revert to an intermittent migraine pattern once the analgesics are stopped. Methods.,Women who were 1 year postcolectomy for ulcerative colitis were identified in several colorectal surgery practices in Calgary. They were sent a questionnaire designed to determine if they had a history of migraine prior to surgery, if they currently had chronic daily headache, what medications they were taking to control bowel motility, and what medications they were taking for headache. Results.,Twenty-eight patients who met our inclusion criteria returned completed questionnaires. Eight of these exceeded the recommended limits for opiate use in patients with headache. Eight patients met diagnostic criteria for migraine. Two patients had chronic daily headache starting after surgery. Both used daily opiates beginning after their surgery, and both had a history of migraine. The other six patients who used opiates daily did not have a history of migraine and did not have chronic daily headache. All patients with migraine who used daily opiates to control bowel motility following surgery developed chronic daily headache after surgery. Conclusions.,Patients with migraine who use daily opiates for any reason are at high risk of developing transformed migraine with chronic daily headache. This risk appears much lower in patients without a history of migraine who use opiates for nonpain indications. [source] Etiology and Distribution of Headaches in Two Brazilian Primary Care UnitsHEADACHE, Issue 3 2000Marcelo E. Bigal MD Objectives.,To determine (a) which patients seek primary care services with a complaint of headache, (b) the percentages of the various types of headache in this population, and (c) the impact of the care provided to these patients on the basic health care network. Background.,Headache is one of the most frequent symptoms reported in medical practice, resulting in significant medical services costs and loss of patient productivity, as well as reduced quality of life. Methods.,A prospective study was conducted in two towns (Ribeirão Preto and São Carlos) in the State of São Paulo, Brazil. The participants in the study consisted of 6006 patients (52.4% women) with highly varied acute symptoms. The patients ranged in age from 14 to 98 years. Results.,Headache as the main complaint was reported by 561 (9.3%) of the patients considered, with 312 (55.6%) of those patients presenting with primary headache, 221 (39.4%) with headaches secondary to systemic disorders, and 28 (5.0%) with headaches secondary to neurological disorders. Migraine, the most prevalent primary headache, accounted for 45.1% of patients reporting headache as the single symptom. The most frequent etiologies of headaches secondary to systemic disorders were fever, acute hypertension, and sinusitis. The most frequent headaches secondary to neurological disorders were posttraumatic headaches, headaches secondary to cervical disease, and expansive intracranial processes. Of the 26 cases of drug abuse, 20 were secondary to alcohol (hangover). Headaches secondary to systemic disorders were more frequent in the extreme age ranges. Conclusions.,Headache is a very frequent symptom among patients seen at primary health care units and should be considered a public health problem. The dissemination of the diagnostic criteria of the International Headache Society among primary health care physicians is urgently needed in order to avoid the repeated return of patients or their referral to more differentiated emergency units, which overburden an already insufficient health care network. [source] Alteration in Nature of Cluster Headache During Subcutaneous Administration of SumatriptanHEADACHE, Issue 1 2000Rachel Hering-Hanit MD Objectives., To document the relationship between the 5-HT receptor agonist sumatriptan and a change in the nature of cluster headache in four cases. To relate the findings to the literature on the use of sumatriptan in both cluster headache and migraine. Background., Studies of the efficacy and adverse effects of long-term treatment with sumatriptan in cluster headache are limited and report conflicting findings. Methods., Four cases are described. Results., All four patients developed a marked increase in the frequency of attacks 3 to 4 weeks after initiating treatment with the drug for the first time. Three patients also developed a change in headache character, and 2 experienced prolongation of the cluster headache period. Withdrawal of the drug reduced the frequency of headaches and eliminated the newly developed type of headache. Conclusions., Determination of the effects of long-term use of sumatriptan will result in more precise guidelines for the frequency and duration of treatment with this otherwise extremely beneficial drug. [source] Does Deinstitutionalization Increase Suicide?HEALTH SERVICES RESEARCH, Issue 4 2009Jangho Yoon Objectives. (1) To test whether public psychiatric bed reduction may increase suicide rates; (2) to investigate whether the supply of private hospital psychiatric beds,separately for not-for-profit and for-profit,can substitute for public bed reduction without increasing suicides; and (3) to examine whether the level of community mental health resources moderates the relationship between public bed reduction and suicide rates. Methods. We examined state-level variation in suicide rates in relation to psychiatric beds and community mental health spending in the United States for the years 1982,1998. We categorize psychiatric beds separately for public, not-for-profit, and for-profit hospitals. Principal Findings. Reduced public psychiatric bed supply was found to increase suicide rates. We found no evidence that not-for-profit or for-profit bed supply compensates for public bed reductions. However, greater community mental health spending buffers the adverse effect of public bed reductions on suicide. We estimate that in 2008, an additional decline in public psychiatric hospital beds would raise suicide rates for almost all states. Conclusions. Downsizing of public inpatient mental health services may increase suicide rates. Nevertheless, an increase in community mental health funding may be promising. [source] | |||||||||||||||||||||||||
