Patterns of pharmacological treatment of patients with migraine, tension-type headache, and cluster headache in a large group of patients in Colombia, 2019.

The objective was to determine the pharmacological treatment patterns of headache disorders in a Colombian population. Cross-sectional study. The dispensations of drugs for the management of tension-type headache, migraine, and cluster headache in the first trimester of 2019 were reviewed from a national medication dispensing database. Sociodemographic, diagnostic, and treatment variables (acute or prophylactic; concomitant drugs) were analyzed. During the study period, 7450 patients were identified: 68.5% with migraine, 25.1% with tension-type headache, and 6.4% with cluster headache. A total of 79.7% (n = 5937) were women, and the mean age was 38.6 ± 14.7 years. The 87.8% (n = 6539) were prescribed drugs for acute pain management, mainly nonsteroidal anti-inflammatory drugs (n = 3559; 47.8%), acetaminophen (n = 3390; 45.5%), ergotamine (n = 2158; 29.0%), and opioids (n = 1750; 23.5%). The 50.3% (n = 3750) received at least one drug used for prophylaxis, mainly antidepressants (n = 1769, 23.7%), flunarizine (n = 927; 12.4%), and ß-blockers (n = 764; 10.3%). The main comedication was proton pump inhibitors (n = 921; 12.4%). Patients with tension-type headache, migraine, and cluster headache receive mainly medications for acute management, some with low therapeutic value or not recommended, such as opioids or ergotamine. Prophylactic management is mainly directed to migraines, although patients with other kinds of headache also used it, even though it was not indicated.

Headache in children with Tourette syndrome.

OBJECTIVE: The authors analyzed the frequency of occurrence of headaches in children and adolescents with Tourette syndrome (TS) to address their possible inclusion as a comorbidity. STUDY DESIGN: Using a prospective questionnaire, administered directly, we interviewed a total sample size of 109 patients with TS ≤ 21 years of age. The questionnaires were then analyzed according to the International Headache Society's diagnostic criteria. RESULTS: We found headaches to be present in 55% of the patients, with the 2 most common headache types being migraine headaches and tension-type headaches. The rate of migraine headache within the TS group was found to be 4 times greater than that of the general pediatric population, as reported in the literature. In addition, the rate of tension-type headache was found to be more than 5 times greater than that of the general pediatric population. CONCLUSIONS: Overall, the high rates of migraine and tension-type headache within this population support the proposition that headaches are a comorbidity of TS.

Devising and validating a headache diary in a series of patients with chronic daily headache from Colombia.

OBJECTIVE: To devise and test the reliability and validity of a brief headache diary in a series of Colombian patients with chronic daily headache. METHODS: The study was designed in five stages: selection of domains (group of patients and experts); initial devising of the items (writing group); identification of non-understandable items (n=20); assessment of internal consistency (n=100); assessment of validity and assessment of sensitivity to change during seven consecutive days (n=25, 175 observations). RESULTS: Five domains were selected: headache presence, severity and length of pain, analgesics intake, and missing workdays. The headache diary is internally consistent (≈75% of rotated variance), correlates with the medical interview (Spearman's rho and Kendall's tau over 0.8 for each domain) and it has an adequate and stable sensitivity and specificity (82 to 96%). CONCLUSIONS: This headache diary is a reliable and valid instrument and represents the most important features affecting Colombian patients with chronic daily headache.

CONCLUSIONES: Este diario de cefalea es un instrumento confiable y registra las principales características de las cefaleas en pacientes con cefalea crónica diaria.

Primary headaches in childhood--a population-based study.

The aim of this study was to estimate the prevalence of primary headaches in pre-adolescent children, as well as headache frequency and days of treatment in this population. Sample consisted of 1994 children (aged 5-12 years). Parents were interviewed by a paediatric headache specialist using a questionnaire that allowed the classification of headaches using the criteria of the Second Edition of the International Classification of Headache Disorders. The most severe headache type was classified (mutually-exclusive diagnoses). Prevalence and prevalence ratios were calculated overall, as well as by age, gender and race. The overall prevalence of migraine was 3.76%, non-significantly higher in boys (3.9%) than in girls (3.6%). Prevalence of probable migraine was significantly higher than the prevalence of migraine for all ages (overall prevalence of 17.1%). Chronic migraine (CM) happened in 0.8% (girls, 1.15%; boys, 0.5%). Infrequent episodic tension-type headache (ETTH) happened in 2.3% of the sample while prevalence of frequent ETTH was 1.6%. Probable TTH happened in 13.5%. Most children with migraine had consulted a medical doctor because of their headaches, and the proportion was higher among children with CM (93.7%). Prevalence of primary headaches is high in young children. Probable diagnoses are more common than full diagnoses. Consultation rates are elevated.

[Prevalence of primary headaches in a rural population in Cuba]. / Prevalencia de cefaleas primarias en una población rural cubana.

AIM: To determine the prevalence and the clinical-epidemiological and therapeutic characteristics of primary headaches in a rural population in Cuba. SUBJECTS AND METHODS: A cross-sectional study was conducted in a rural population of the Policlinica Mabay in the province of Granma, Cuba. The second International Headache Society classification was used. Sample size, which was calculated by means of the program EpiInfo 2002, was 360 adult workers over 18 years of age, who were selected by simple random sampling. RESULTS: The prevalence of primary headaches was 44.72%. There was a predominance of females (71.4%). 31.1% of cases were between 50 and 59 years old. 36.6% had a family history of headaches. Onset of headaches occurred before the age of 15 years in 44.1% of patients. The most frequent location was occipital (45.3% of cases). The most frequent precipitating factors were stress (27.9%) and menstruation (27.3%). The predominant accompanying symptom was dizziness (26.1%). Tension-type headache was the most prevalent, with 92 patients (25.56%), followed by migraine, with 61 diagnoses (16.94%). 78.3% of the patients with tension-type headache and 70.5% of those with migraine tried self-medication with dipyrone and paracetamol. Patients with migraine made more frequent use of prophylactic treatment than those who suffered from tension-type headache (32.8% versus 16.3%; p = 0.01). CONCLUSIONS: The prevalence of primary headaches is high in the rural population under study; the high rate of prescription drug abuse (mainly painkillers and non-steroidal anti-inflammatory drugs) has led to a significant number of headaches becoming chronic. This health problem is also seen to have an important effect on occupational affairs.

Local infiltration of gonyautoxin is safe and effective in treatment of chronic tension-type headache.

BACKGROUND: Gonyautoxin are phycotoxins, whose molecular mechanism of action is a reversible block of the voltage-gated sodium channels at axonal level, impeding nerve impulse propagation. OBJECTIVE: To evaluate clinical efficacy of gonyautoxin in the treatment of patients with chronic tensional-type headache. METHODS: Open trial from September 2004 to 2005 in Hospital Clínico Universidad de Chile. Twenty-seven patients with chronic tension-type headache were locally infiltrated with gonyautoxins (50 micrograms) in ten sites considered as pain trigger points in a fixed infiltration protocol. In each site, a volume of 200 microlitres was injected. EMG recording was performed before and immediately after infiltrations. Main outcome measures are where a significantly drop-off in acute headache pain score occurs and number of days without headache pain. RESULTS: No side effects were detected in the follow-up period. From base line of 2 weeks, 19 patients of 27 (70%) are the successfully responders to the treatment. They showed the remarkable immediate effect after infiltration demonstrated by trapezium EMG recording. Patients reported a fall in pain score 5 minutes post-injection from 5.0 +/- 2.8 to 1.6 +/- 1.6 (mean +/- SD). The responder showed an average of 8.1 +/- 9.9 weeks of headache pain-free, all of them without a second infiltration or use of any additional analgesic medication. DISCUSSION: The therapeutic properties of gonyautoxin local infiltration in chronic tension-type headache patients are shown to be safe and effective. This report describes a new therapy for chronic tension-type headache involving local infiltrations of gonyautoxins. The immediate headache pain relief effect shown only minutes after toxin infiltrations were the most remarkable feature of this protocol. This is the first gonyautoxins testing report in the treatment of chronic tension-type headache.

Tension-type headache.

Tension-type headache (TTH) is the most prevalent of all headaches and also represents one of the most expensive clinical conditions for the health system. Despite the high impact of this disorder and the existence of well-established diagnostic criteria, knowledge about TTH is still quite limited. In most cases in which crises are quite sporadic, the patients call this normal headache. However, there is a group of patients with the chronic subtype of this headache whose quality of life is greatly compromised. According to the second edition of the International Classification of Headache Disorders, TTH is a bilateral headache of the tight band of pressure type of mild-to-moderate intensity that does not worsen with routine physical activities and whose associated symptoms are less intense than those observed in migraine. Its physiopathology still awaits better elucidation but the existence of central and peripheral mechanisms is already recognized. From a therapeutic viewpoint, simple analgesics are used for the acute treatment of the condition, and tricyclic antidepressants are the most effective class of drugs for its prevention. Follow-up of these patients over the years has demonstrated that the course of TTH is quite favorable in most cases.

Cefalea recurrente en la consulta de neurología del Hospital Nacional de Niños: 2001-2002: [revisión] / Recurrent headache in the neurology department of Hospital Nacional de Niños: 2001-2002: [review]

Se estudiaron retrospectivamente, 78 pacientes con cefalea recurrente referidos al servicio de Neurología del HNN durante los años 2001 y 2002. 51 por ciento de los pacientes venían referidos por un pediatra, con un tiempo de espera para ser atendidos en el HNN, menor de dos meses (80 por ciento). El grupo representó el 16,5 por ciento de la consulta de pacientes nuevos. 43 varones (55.1 por ciento) y 35 mujeres (44.9 por ciento), de 2 a 13 años de edad (promedio 8), tenían menos de 1 año de evolución de cefalea (50 por ciento), de intensidad moderada (70 por ciento), pulsátil (70 por ciento) y asociada a náuses, vómitos, defectos visuales y fotofobia en 36, 30, 27 y 13 pacientes respectivamente. En 36 niños no se reportó ningún factor desencadenante pero el estrés precipitaba los síntomas en 35 casos. El 72 por ciento tenían el antecedente familiar de migraña. A 61 pacientes se les realizó una tomografía axial computarizada (TAC), que fue normal en 59, uno tenía atrofia cortical y subcortical y otro hallazgos sugestivos de neurocisticercosis. Los diagnósticos principales fueron migraña (95 por ciento) y cefalea tensional (3 por ciento), con respuesta satisfactoria (85 por ciento de los casos) a las recomendaciones, analgésicos o al tratamiento preventivo, permitiendo remitirles (75 por ciento) a sus consultas de origen. Niños con cefalea recurrente y examen neurológico normal deben recibir recomendaciones, información y seguimiento, no siendo generalmente necesario referir a Neurología, hacer exámenes paraclínicos ni hospitalizar.

Cefaléia do tipo tensional crônica: tratamento alternativo com neuroestimulação elétrica transcutâncea / Alternative treatment with the transcutaneous electrical nerve stimulation (TENS)

Resumo: A neuroestimulação elétrica transcutânea foi avaliada no tratamento da cefaléia do tipo tensional crônica para o que foram selecionados 32 pacientes do ambulatório de Cefaléia do HC-UFPE que preenchiam os critérios diagnósticos emitidos pela SIC e que não estavam em uso de medicação profilática. Na consulta inicial lhe era entregue um diário no qual deviam registrar, por 30 dias consecutivos, os dias com dor e a intensidade de suas algias. Retornavam ao fim de 30 dias quando eram computados o número de dias com dor e estabelecido o escore da dor este representado pôr um número obtido da soma das parcelas: (Nº de dias com dor muito forte x 4) + (Nº de dias com dor forte x 3) (+ Nº de dias com dor fraca x 1 ). Iniciavam o tratamento submetendo-se a três sessões de 30 minutos cada e eram revistos após seis (15 dias) e 12 (30 dias) sessões, os dados assinalados no diário eram então computados e cortejados com os registros na fase pré tratamento. Dezoito dos pacientes, por razões várias, foram afastados do estudo. Dos 14 que completaram apenas três obtiveram resultados: satisfatório em dois (melhora de 83,64por cento no nº de dias com dor e em igual percentual no escora da dor); redução de 70por cento no nº de dias com dor e de 77,56por cento no escore da dor) e pouco significativo (redução de 41,18por cento no nº de dias com dor e de 43,34por cento no escore da dor). Em conclusão a neuroestimulação elétrica transcutânea se mostrou ineficaz no tratamento da cefaléia do tipo tensional crônica

Intravenous dipyrone for the acute treatment of episodic tension-type headache: a randomized, placebo-controlled, double-blind study.

Acute headaches are responsible for a significant percentage of the case load at primary care units and emergency rooms in Brazil. Dipyrone (metamizol) is easily available in these settings, being the most frequently used drug. We conducted a randomized, placebo-controlled, double-blind study to assess the effect of dipyrone in the acute treatment of episodic tension-type headache. Sixty patients were randomized to receive placebo (intravenous injection of 10 ml saline) or 1 g dipyrone in 10 ml saline. We used seven parameters of analgesic evaluation. The patients receiving dipyrone showed a statistically significant improvement (P<0.05) of pain compared to placebo up to 30 min after drug administration. The therapeutic gain was 30% in 30 min and 40% in 60 min. The number of patients needed to be treated for at least one to have benefit was 3.3 in 30 min and 2.2 in 60 min. There were statistically significant reductions in the recurrence (dipyrone = 25%, placebo = 50%) and use of rescue medication (dipyrone = 20%, placebo = 47.6%) for the dipyrone group. Intravenous dipyrone is an effective drug for the relief of pain in tension-type headache and its use is justified in the emergency room setting.

Intravenous chlorpromazine in the acute treatment of episodic tension-type headache: a randomized, placebo controlled, double-blind study.

Acute headache is a very frequent symptom, responsible for a significant percentage of caseload at primary care units and emergency rooms. Chlorpromazine is easily available in such settings. The aim of this study is to conduct a randomized, placebo-controlled, double-blind study to assess the efficacy of chlorpromazine on the acute treatment of episodic tension-type headache. We randomized 30 patients to receive placebo (10 ml of saline intravenous injections) and 30 patients to receive 0.1 mg/Kg chlorpromazine intravenously. We used 7 parameters of analgesic evaluation. Patients receiving chlorpromazine showed a statistically significant improvement (p < 0.05 and p < 0.01) of pain compared to placebo, far up to 30 minutes after the drug administration. The therapeutic gain was 36.7% in 30 minutes and 56.6 % in 60 minutes. The number needed to treat (NNT, the reciprocal or the therapeutic gain) was 2.7 in 30 minutes and 1.8 in 60 minutes. There were reductions in the recurrence and in the use of rescue medication in the chlorpromazine group. We can conclude that intravenous chlorpromazine is an effective drug to relief the pain in tension-type headache.

[Evaluation of placebo use in migraine without aura, migraine with aura and episodic tension-type headache acute attacks]. / Avaliação da utilização do placebo nas crises agudas de migrânea sem aura, migrânea com aura e cefaléia do tipo tensional episódica.

This study presents an evaluation of placebo response in the acute treatment of migraine with or without aura and episodic tension type headache. We studied patients admitted between March 1st,1997 and November 31st,1999 in two Emergency Room Units. Three groups had been defined, each one with 30 participants: migraine without aura (MWOA), migraine with aura (MWA) and episodic tension-type headache (ETTH). Patients were participating of a randomized study to evaluate efficacy of 4 different drugs; those randomized to receive placebo were included. We evaluated pain and associated symptoms. After one hour of placebo administration, 50% of MWOA patients, 23.3% of MWA and 26.7% of ETTH had presented pain relief. The mean of this relief, evaluated by the numerical pain scale, was 41.6%, 23.1% and 36%, respectively. Use of placebo is essential in evaluating the therapeutic role of drugs used in the treatment of acute headache.

Avaliaçäo da utilizaçäo do placebo nas crises agudas de migrânea sem aura, migrânea com aura e cefaléia do tipo tensional episódica / Evaluation of placebo use in migraine without aura, migraine with aura and episodic tension-type headache acute attacks

O presente estudo apresenta a avaliação do efeito placebo no tratamento agudo da migrânea sem aura, migrânea com aura e cefaléia do tipo tensional episódica. Foram estudados pacientes que deram entrada entre 1 de março de 1997 a 31 de novembro de 1999 em dois pronto-socorros. Definiram-se três grupos, cada um com 30 pacientes: 1 - migrânea sem aura (MSA); 2 ó migrânea com aura (MCO); 3 ó cefaléia do tipo tensional episódica (CTTE). Os pacientes participavam de estudo randomizado para avaliar a eficácia de 4 drogas; aqueles randomizados para o placebo foram incluídos também. Os parâmetros avaliados foram: 1 ó dor; 2 - sintomas associados. Avaliados uma hora após a administração do placebo, 50 por cento dos pacientes do grupo MSA, 23,3 por cento dos pacientes do grupo MCA e 26,7 por cento dos pacientes do grupo CTTE apresentavam melhora da dor. A melhora, avaliada pela escala numérica da dor foi, em média, de 41,6 por cento, 23,1 por cento e 36 por cento, respectivamente. Houve também redução significativa de todos os sintomas associados. A utilização do placebo é, portanto, essencial na avaliação de drogas utilizadas no tratamento de cefaléias agudas.

Intravenous metamizol (Dipyrone) in acute migraine treatment and in episodic tension-type headache--a placebo-controlled study.

Acute headache is a very frequent symptom, responsible for significant demand at primary care units and emergency rooms. In such sets in Brazil, metamizol is easily found but, on the other hand, neither ergotics nor triptans are available. The aim of this study is to compare intravenous metamizol with placebo in the acute treatment of migraine with aura, migraine without aura and episodic tension-type headache. Fifty-four migraine with aura patients, 95 migraine without aura patients and 30 tension-type headache patients were treated with metamizol. Ninety patients (30 migraine with aura, 30 migraine without aura and 30 tension-type headache patients) received placebo. Pain intensity, nausea, aura, photo- and phonophobia were investigated at 30 min and 60 min after the administration of the drug. Significant improvement of pain after 30 min and 60 min post-dosage was achieved from metamizol groups compared with placebo groups. Significant improvement of all other symptoms was achieved after 60 min post-dosage. Side-effects were mild and with small incidence. Metamizol is an effective, safe and low price drug. It may be regarded as a good alternative drug for the treatment of common acute primary headaches.

[Clinical evaluation of the efficacy of the paracetamol and caffeine combination in the treatment of tension headache]. / Avaliação clínica da eficácia da combinação paracetamol e cafeína no tratamento da cefaléia tipo tensão.

Tension type headache in both its forms, episodic and chronic, is the most common type of headache experienced by the population. The headache attack or the prevention of new crises may be treated with pharmacological as well as non-pharmacological measures. This study included 5,490 patients from out-patient clinics and medical offices covering various regions of Brazil. Approximately 95% of the subjects had episodic tension type headache, while 5% had chronic tension type headache. The majority of the patients presented with crisis of moderate intensity (62.19%). In 5,419 patients a tension type headache crisis was treated with acetaminophen 1000 mg and caffeine 130 mg. In 93.98%, onset of relief occurred within 2 hours of taking the medication. In 77.61%, complete reversion of the crisis occurred within 2 hours. Good/excellent efficacy ratings were achieved in 61.93%/37.80% of the cases according to the physician's assessment and in 48.51%/40.29% according to the patients' assessment. Adverse events, commonly gastrointestinal manifestations, were reported by 5.57% of the patients. This is a Brazilian study of the efficacy and safety of the combined use of acetaminophen-caffeine for the treatment of tension type headache.
