Progression of subclinical cardiovascular disease in patients with HIV.

OBJECTIVE: Human immunodeficiency virus (HIV) infected patients are at increased risk of cardiovascular disease (CVD). Multidetector computed tomography (MDCT) stratifies cardiovascular risk in asymptomatic patients with subclinical atherosclerosis. The aim of this study was to determine the ability of MCTD and clinical and laboratory parameters to assess subclinical CVD progression in HIV patients. METHODS: Prospective longitudinal cohort study of patients with at least 10 years of HIV infection and 5 years of antiretroviral therapy history, low cardiovascular risk and monitored for 6 years (2015-2021). All patients underwent clinical assessment, blood analysis, carotid ultrasound, and gated MDCT in 2015 and 2021. RESULTS: Sixty-three patients (63.5% male) with a mean age of 49.9 years (standard deviation [SD], 10.5) were included in 2015; 63 of them were followed until 2021. Comparing the results from 2015 with those from 2021, Systematic Coronary Risk Estimation-2 (SCORE2) was 2.9% (SD, 2.1) vs. 4.4% (SD,3.1); Multi-Ethnic Study of Atherosclerosis score (MESA risk) was 3.4 (SD 5.8) vs. 6.0 (SD 8.6); coronary artery calcification CAC) score >100 was 11.1% vs. 25.4% (P < 0.05); and 11% vs. 27% had carotid plaques (P = 0.03). CONCLUSIONS: After six years of follow-up, an increase in SCORE2, carotid plaques, CAC scoring and MESA risk was observed. MDCT findings, along with other clinical and laboratory parameters, could play an important role as a marker of CVD progression in the evaluation of patients with HIV and low cardiovascular risk.

The MIGREX study: Prevalence and risk factors of sexual dysfunction among migraine patients.

BACKGROUND: Migraine attacks have a high impact on daily activities. There is limited research on the burden of migraine on sexual functioning. OBJECTIVE: To determine the prevalence of sexual dysfunction in patients with migraine and its relationship with migraine features and comorbidities. METHOD: This is a cross-sectional study. We included migraine patients between 18 and 60 years-old from 8 Headache Clinics in Spain. We recorded demographic data and migraine features. Patients fulfilled a survey including comorbidities, Arizona Sexual Experiences Scale, Hospital Anxiety and Depression Scale and a questionnaire about migraine impact on sexual activity. A K-nearest neighbor supervised learning algorithm was used to identify differences between migraine patients with and without sexual dysfunction. RESULTS: We included 306 patients (85.6% women, mean age 42.3±11.1 years). A 41.8% of participants had sexual dysfunction. Sexual dysfunction was associated with being female (OR [95% CI]: 2.42 [1.17-5.00]; p<0.001), being older than 46.5 years (4.04 [2.48-6.59]; p<0.001), having chronic migraine (2.31 [1.41-3.77]; p=0.001), using preventive medication (2.45 [1.35-4.45]; p=0.004), analgesic overusing (3.51 [2.03-6.07]; p<0.001), menopause (4.18 [2.43-7.17]; p<0.001) and anxiety (2.90 [1.80-4.67]; p<0.001) and depression (6.14 [3.18-11.83]; p<0.001). However, only female gender, age, menopause and depression were the statistically significant variables selected in the model to classify migraine patients with or without sexual dysfunction (Accuracy [95% CI]: 0.75 (0.62-0.85), Kappa: 0.48, p=0.005). CONCLUSIONS: Sexual dysfunction is frequent in migraine patients visited in a headache clinic. However, migraine characteristics or use of preventive medication are not directly associated with sexual dysfunction. Instead, risk factors for sexual dysfunction were female gender, higher age, menopause and depression.

[Peripheral stimulation of the trigeminal nerve by nasopharyngeal swabbing as a possible trigger of migraine attacks]. / Estimulación periférica del nervio trigémino mediante frotis nasofaríngeo como posible desencadenante de migraña.

INTRODUCTION: The role of the central and peripheral nervous system in the generation of migraine is not well understood. Our aim was to determine whether peripheral trigeminal nerve stimuli, such as nasopharyngeal swabs, could trigger migraine attacks. SUBJECTS AND METHODS: A survey was sent to 658 doctors, nurses and medical students, asking about the presence of headache suggestive of migraine after carrying out a SARS-CoV-2 swab test, their previous history of migraine, and demographic and headache-related characteristics. Those who tested positive or had associated clinical signs and symptoms of COVID were excluded. RESULTS: A total of 377 people were recruited, 309 of whom were included in the sample. Forty-seven (15.2%) reported headache suggestive of migraine after the swab test and 42 (89.4%) of them had a previous history of migraine. The risk of developing migraine was higher in the subgroup of patients with a history of headache suggestive of migraine - odds ratio: 22.6 (95% confidence interval: 8.597-59.397); p < 0.001. No differences were found between the main characteristics of attacks suggestive of migraine before and after the swab test, except for a lower percentage of associated aura afterwards (42.8% vs. 26.1%; p = 0.016). Individuals with previous attacks suggestive of migraine with a frequency of more than two episodes per month had a higher risk of developing a headache suggestive of migraine after the test - odds ratio = 2.353 (95% confidence interval: 1.077-5.145); p = 0.03. CONCLUSIONS: Nasopharyngeal swabbing may trigger migraine attacks, with a greater likelihood in individuals with a higher frequency of previous migraines. This would confirm the idea that peripheral stimuli on the trigeminal nerve can trigger migraine attacks in individuals with migraine, according to their degree of trigeminovascular sensitisation.

TITLE: Estimulación periférica del nervio trigémino mediante frotis nasofaríngeo como posible desencadenante de migraña.Introducción. La implicación del sistema nervioso central y periférico en la generación de la migraña no se conoce bien. Nuestro objetivo fue determinar si estímulos periféricos sobre el nervio trigémino, como el frotis nasofaríngeo, podrían desencadenar ataques de migraña. Sujetos y métodos. Se envió una encuesta a 658 médicos, enfermeras y estudiantes de medicina, preguntando por la presencia de cefalea sugestiva de migraña tras la realización de un frotis para la determinación del SARS-CoV-2, su historia previa de migraña, y sobre características demográficas y relacionadas con la cefalea. Los que tenían resultado positivo o que asociaban sintomatología de COVID fueron excluidos. Resultados. Se reclutó a 377 personas y se incluyó a 309. Cuarenta y siete (15,2%) refirieron cefalea sugestiva de migraña tras la realización del frotis, de las cuales 42 (89,4%) tenían historia previa de migraña. El riesgo de desarrollarla fue mayor en el subgrupo de pacientes con cefalea sugestiva de migraña previa ­razón de probabilidad: 22,6 (intervalo de confianza al 95%: 8,597-59,397); p < 0,001­. No hubo diferencias entre las características principales de los ataques sugestivos de migraña previos y los desencadenados tras la prueba, excepto un porcentaje menor de aura asociada tras el frotis (42,8% frente a 26,1%; p = 0,016). Los individuos con ataques sugestivos de migraña previos con frecuencia superior a dos episodios mensuales presentaron mayor riesgo de desarrollar una cefalea sugestiva de migraña tras el test ­razón de probabilidad = 2,353 (intervalo de confianza al 95%: 1,077-5,145); p = 0,03­. Conclusiones. El frotis nasofaríngeo podría desencadenar ataques de migraña, más probablemente en individuos con mayor frecuencia de migrañas previas. Esto confirmaría que estímulos periféricos sobre el nervio trigémino pueden desencadenar ataques de migraña en individuos con migraña, de acuerdo con su grado de sensibilización trigeminovascular.

Evaluation of endothelial function and subclinical atherosclerosis in patients with HIV infection.

The aim of this study was to analyse the association between human immunodeficiency virus (HIV) related clinical and analytical parameters and the presence of subclinical atherosclerosis as well as endothelial dysfunction. This was a prospective cohort study of HIV-positive patients who underwent intima media thickness (IMT) determination and coronary artery calcium scoring to determine subclinical atherosclerosis. To detect endothelial dysfunction, the breath holding index, flow-mediated dilation and the concentration of endothelial progenitor cells (EPCs) were measured. Patients with an IMT ≥ 0.9 mm had an average of 559.3 ± 283.34 CD4/µl, and those with an IMT < 0.9 mm had an average of 715.4 ± 389.92 CD4/µl (p = 0.04). Patients with a low calcium score had a significantly higher average CD4 cell value and lower zenith viral load (VL) than those with a higher score (707.7 ± 377.5 CD4/µl vs 477.23 ± 235.7 CD4/µl (p = 0.01) and 7 × 104 ± 5 × 104 copies/ml vs 23.4 × 104 ± 19 × 104 copies/ml (p = 0.02)). The number of early EPCs in patients with a CD4 nadir < 350/µl was lower than that in those with a CD4 nadir ≥ 350 (p = 0.03). In HIV-positive patients, low CD4 cell levels and high VL were associated with risk of developing subclinical atherosclerosis. HIV patients with CD4 cell nadir < 350/µl may have fewer early EPCs.

Headache as main reason for consultation to a hospital Emergency Department in Spain: a prospective study. / La cefalea como motivo principal de consulta a un servicio de urgencia hospitalaria en España: un estudio prospectivo.

INTRODUCTION: Headache is common in the general population and a frequent reason for medical consultation. OBJECTIVES: To describe the characteristics of patients attending the Emergency Department (ED) for headache. METHODS: A descriptive study with prospective collection of 100 consecutive patients over 15 years old who attended our ED due to headache as the main complaint. RESULTS: Headache accounted for 1,4% of ED visits. The most common age range is between 31 and 45 years and the majority of the patients are females (61%). We diagnosed 67 primary and 33 secondary headaches. The most frequent diagnosis was migraine, with 36% of cases. One out of 3 patients had a history of headache and 4 out of 5 consulted by their own decision. Only a small percentage of patients were admitted as inpatients (12%), and 3 out of 5 were referred to Primary Care. Complementary tests were performed on 84% of the patients. One CT scan was performed for every 3 patients. A total of 80% patients was correctly diagnosed by the ED physicians. CONCLUSIONS: Headache is a frequent complaint in the ED, where primary headaches are the most common with migraine being the most frequent reason for consultation. In our setting, there is a good screening and diagnosis of headaches, as well as an adequate use of the available resources in the ED for their diagnosis and management.

How and when to refer patients diagnosed with secondary headache and other craniofacial pain in the Emergency Department and Primary Care: Recommendations of the Spanish Society of Neurology's Headache Study Group. / Cómo y cuándo derivar un paciente con cefalea secundaria y otros tipos de dolores craneofaciales desde Urgencias y Atención Primaria: recomendaciones del Grupo de Estudio de Cefaleas de la Sociedad Española de Neurología.

INTRODUCTION: When secondary headache is suspected and the patient is referred to the emergency department or to the outpatient neurology clinic, it is important to know which are the appropriate complementary examinations to perform and the suitable referral pathway for patients to follow. In order to establish recommendations on this matter, the Spanish Society of Neurology's Headache Study Group (GECSEN) has decided to issue a series of agreed recommendations constituting a referral protocol for patients with headache and/or craniofacial neuralgias. DEVELOPMENT: Young neurologists with an interest and experience in headache were invited to draft a series of practical guidelines in collaboration with GECSEN's Executive Committee. For practical reasons, the document was divided into 2 articles: the first focuses on primary headaches and craniofacial neuralgias and this second article on secondary headaches and other craniofacial pain. In order for the recommendations to be helpful for daily practice, they follow a practical approach, with tables summarising referral criteria, examinations to be performed, and referral to other specialists. CONCLUSIONS: We hope to offer a guide and tools to improve decision-making regarding patients with headache, identifying complementary tests to prioritise and referral pathways to be followed, in order to avoid duplicated consultations and delayed diagnosis and treatment.

[Real need for headache services and their resource consumption: a retrospective observational study on a cohort in Cantabria]. / Necesidad real y consumo de recursos en las unidades de cefalea: estudio observacional retrospectivo sobre una cohorte en Cantabria.

INTRODUCTION: Headache services arise out of a need to improve care for patients with different types of headache; however, some important aspects of clinical management that demonstrate their efficiency remain unknown. AIM: To estimate the need for headache services in our area. PATIENTS AND METHODS: We conducted a retrospective study in two phases: identification of the first visits due to headache during three consecutive months and collection of care data during one year. The care criteria in headache services considered were: chronic migraine, rare headaches, need for special techniques and headaches with poor therapeutic response. RESULTS: Of the 1,418 first visits, in 298 cases (20.38%) the reason for seeking medical attention was headache. Of these, 82.9% were from primary care. The distribution of the diagnoses was: 54%, migraine; 11%, tension-type headache; and 35%, other headaches. Altogether 108 patients met the criteria for referral to headache services: 63 for chronic migraine; 13 for nerve blocks; 9 for frequent migraine; 8 for trigeminal-autonomic cephalgias; 5 due to a need for botulinum toxin; and 10 for other reasons. The patients attended by headache services went to the emergency department less often than those who visited the general outpatient department, had fewer brain scans and more botulinum toxin was indicated. CONCLUSION: Headache services are justified because they offer better management of patients with the most severe variants of headache. In our country, at least two visits a week are needed to cover an area of 350,000 users of the Spanish National Health System.

Las unidades de cefalea surgen por una necesidad de mejorar la asistencia a los pacientes con cefalea; no obstante, se desconocen aspectos importantes de gestion clinica que demuestren su eficiencia. Objetivo. Estimar la necesidad de unidades de cefalea en nuestro medio. Pacientes y metodos. Estudio retrospectivo realizado en dos fases: identificacion de las primeras consultas por cefalea durante tres meses consecutivos y recogida de datos asistenciales ocurridos durante un año. Criterios de asistencia en unidades de cefalea: migraña cronica, cefaleas raras, necesidad de tecnicas especiales y cefaleas con mala respuesta terapeutica. Resultados. De las 1.418 primeras consultas, en 298 (20,38%) la cefalea fue el motivo asistencial. El 82,9% procedia de atencion primaria. La distribucion de diagnosticos fue: 54% migraña, 11% cefalea tensional y 35% otras cefaleas. Un total de 108 pacientes cumplia los criterios de derivacion a unidades de cefalea: 63 por migraña cronica, 13 por bloqueos nerviosos, 9 por migraña frecuente, 8 por cefaleas trigeminoautonomicas, 5 por necesidad de toxina botulinica y 10 por otros motivos. Los pacientes atendidos por unidades de cefalea acudieron menos veces a urgencias que los de consulta general, se les realizaron menos tomografias cerebrales y se les indico mas toxina botulinica. Conclusion. Las unidades de cefalea estan justificadas por gestionar mejor los pacientes con las variantes mas graves de cefalea. En nuestro medio se justifican al menos dos consultas semanales para atender un area de 350.000 usuarios del Sistema Nacional de Salud.

Headache: What to ask, how to examine, and which scales to use. Recommendations of the Spanish Society of Neurology's Headache Study Group. / ¿Qué preguntar, cómo explorar y qué escalas usar en el paciente con cefalea? Recomendaciones del Grupo de Estudio de Cefalea de la Sociedad Española de Neurología.

INTRODUCTION: Headache is the most common neurological complaint at the different levels of the healthcare system, and clinical history and physical examination are essential in the diagnosis and treatment of these patients. With the objective of unifying the care given to patients with headache, the Spanish Society of Neurology's Headache Study Group (GECSEN) has decided to establish a series of consensus recommendations to improve and guarantee adequate care in primary care, emergency services, and neurology departments. METHODS: With the aim of creating a practical document, the recommendations follow the dynamics of a medical consultation: clinical history, physical examination, and scales quantifying headache impact and disability. In addition, we provide recommendations for follow-up and managing patients' expectations of the treatment. CONCLUSIONS: With this tool, we aim to improve the care given to patients with headache in order to guarantee adequate, homogeneous care across Spain.

Stress at work in migraine patients: differences in attack frequency.

INTRODUCTION: Migraine is a common and prevalent disease that contributes to health expenditure and interferes with quality of life. Our goal was to analyse the level of stress at work in a sample of migraine and its possible association with the chronicity of the process MATERIAL AND METHODS: We applied the Maslach Burnout Inventory, consisting of 22 items grouped into blocks that assess emotional exhaustion (EE), personal accomplishment (PA), depersonalisation at work (DP)] and positive influence (PI), to 94 consecutive subjects recruited in the outpatient clinic. Differences were compared between clinical groups (chronic migraine [CM]: > 15 days/month with headache over a 3-month period vs episodic migraine [EM]: < 15 days/month with headache) using the general linear model adjusted for age and MIDAS score RESULTS: The mean age was higher in the CM group. Mean MIDAS scores were 51 ± 4.1 in CM, and 17.7 ± 15 in EM (P=.001). Adjusted means for EE were 24.6 ± 2.6 in CM patients, 16.2 ± 2.6 in EM patients, and 13.4 ± 2.3 (P=.03) in the healthy group. MIDAS scale scores were inversely correlated to PA (P<.05) DISCUSSION: Our results suggest that the level of EE at work is higher in EM than in CM patients, while PA levels decrease as impact on the MIDAS scale increases. The Maslach scale is a potentially useful tool for studying migraine impact. Surprisingly, EE is higher in patients with fewer episodes; this tendency could be related to stress adaptation mechanisms present in patients with chronic illness.

Cluster-tic syndrome as the initial manifestation of multiple sclerosis.

We report the case of a patient diagnosed as having cluster-tic syndrome as the initial manifestation of multiple sclerosis (MS). The patient's headache bouts improved after treatment with antiepileptic drugs, steroids, and beta-interferon. Magnetic resonance imaging (MRI) scans showed a pontine demyelinating lesion involving the area of the trigeminal root inlet and main sensory nucleus. Neurophysiological studies correlated well with MRI lesions. The association between cluster-tic syndrome and MS is an exception, and the mechanism of the pain is still unknown; therefore, this case might suggest a pathophysiological relationship between the trigeminal main sensory nucleus and cluster-tic syndrome.
