Atypical Facial and Head Pain in Childhood and Adolescence.

PURPOSE OF REVIEW: This review will consider forms of atypical facial and head pain in children and adolescents. A brief and general overview of typical head and facial pains and treatments will be offered. Moreover, atypical head and face pain will be discussed with treatment options. RECENT FINDINGS: The most recent literature including case reports will be evaluated; possible pathophysiological mechanisms, resulting disabilities, and family and social impact will be discussed. General indications for pharmacological treatment will be reviewed, when needed in more disabling cases. Also, non-pharmacological treatments that are especially suitable for this category of patients will be illustrated and discussed.

Understanding of headache patterns modification in an emergency department during the economic crisis of Greece.

Very few neurological research is published regarding health effects of global economic crisis. Our aim was to assess the impact of economic recession on frequency and severity of headaches. We also tested if depression, anxiety and experiences associated with crisis, such as unemployment, were reflected in headaches. This is a retrospective observational study in the Emergency setting of tertiary Clinic from 1 January 2008 until 31 December 2009 and from 1 January 2010 until 31 December 2011. Demographic data were collected of 1094 consecutive adult patients with headache. Multinomial logistic regression performed to examine if hospital anxiety depression (HAD), HAD anxiety, experience of serious life events, year of survey had influence on type of headache. The total number of headache cases increased significantly from 2008 to 2011 (p < 0.001). Tension type and medication overuse headaches remained unchanged over time (p > 0.05), while migraines decreased. Secondary and not otherwise specified (NOS) increased significantly (p < 0.05). The most common, overtime, was Tension type headache, followed by migraines (in 2008, 2011) and NOS (2010). Chi square test showed significant correlation between type of headache and year, as well medication type and year (p < 0.05). Common analgesics, the most common medication, increased five times during survey period (77 % 2008 to 87.6 % 2011). Multivariate analysis revealed stronger association for experience serious events with NOS vs. tension type headache [odds ratio (OR) 0.13; 95 % confidence interval (CI) 0.03, 0.7]. This is the first study showing that the prolonged economic crisis affected headache frequency accompanied by a higher use of analgesics.

Prevalence of abdominal migraine and recurrent abdominal pain in a Japanese clinic.

Prevalence of abdominal migraine (AM) and recurrent abdominal pain (RAP) was evaluated in patients who visited Hikita Pediatric Clinic between May 2010 and April 2015. Patient data were collected prospectively using a questionnaire. Out of a total of 3611 cases, observed prevalence was 2.44% for repeated abdominal pain over a period of ≥3 months, 1.47% for RAP, and 0.19% for AM. Duration of abdominal pain was longer for AM than for non-AM RAP. Certain clinical features were significantly different between AM and non-AM RAP. No correlations were found among age at onset, frequency of attack, and duration of attack for various types of RAP. It was difficult to determine useful diagnostic criteria for distinguishing between AM and non-AM RAP. They did not appear to be separate disease entities but, instead, lie on a disease spectrum. The present prevalence of AM (0.19%) was lower than that in many previous studies from countries other than Japan.

Description of series of 10 patients with hypnic headache: Discussion of the diagnostic criteria.

INTRODUCTION: Hypnic headache is a rare primary headache. The diagnostic criteria of the International Headache Classification (IHS) for this condition are discussed, as they have been modified in the new edition of the 2013. PATIENTS AND METHODS: The clinical characteristics, and fulfilment of the criteria of the IHS classification in a series of 10patients diagnosed in our Headaches Clinic, are analyzed. RESULTS: The mean age of onset of symptoms was 52.1years (SD: 13.4; range: 28-69). The pain was reported as oppressive in 60% of the patients, and as sharp in 30%. The headache was described as holocranial in 60% and hemicranial in 40%. They occurred exclusively during night-time sleep in 80% of the patients. The mean duration of headache was 136.5minutes (range: 10-480). The mean number of days per month was 16.4 (range: 3-30), and 50% had less than 15 headache days per month. No patient had autonomic manifestations, 70% had phonophobia, 50% had photophobia, and 50% had both. All of them (100%) had a VAS score equal to or higher than 8. CONCLUSIONS: The criteria for hypnic headache of the new classification are best suited to the characteristics of these patients. Our results show the major changes in the criteria: pain is not always dull, headache frequency may be less than 15days a month, and it can occur in people under age 50. There may be phonophobia or photophobia only, or both. Although it does not form part of the diagnostic criteria, the pain intensity in our series was higher than described.

[Diagnostic controversies on the International Classification of Headaches Disorders, III Edition]. / Controversias diagnósticas en la Clasificación Internacional de las Cefaleas, III Edición.

The review considered points of conflict that may lead to confusion in the daily use of the International Classification of Headache Disorders (ICHD-III). Both the controversies at the time of preparing the criteria and the overlaps produced after their use in daily practice were evaluated, argued through scientific bibliography. As relevant points, the anamnesis of a patient with headache should indicate the intensity of the pain as well as the duration of the painful episode and if its location is strictly unilateral. These points may be helpful in cases of moderate pain that do not fully meet the criteria for any of the primary headaches, a frequent dilemma in daily practice.

La revisión consideró los puntos de conflicto que puedan llevar a confusión en el uso diario de la clasificación internacional de las cefaleas (ICHD-III). Se evaluaron tanto las controversias al momento de confeccionar los criterios como las superposiciones producidas tras su utilización en la práctica diaria, argumentado a través de bibliografía científica. Como puntos relevantes, la anamnesis de un paciente con cefalea debe indicar la intensidad del dolor como así también la duración del episodio doloroso y si su localización es estrictamente unilateral. Estos puntos podrán ser de ayuda en los casos de dolor moderado que no cumplan en forma absoluta los criterios para ninguna de las cefaleas primarias, dilema frecuente en la práctica diaria.

The Pediatric Trochlear Migraine: Diagnostic and Therapeutic Implications.

Trochlear Migraine has been recently described as the concurrence of strictly unilateral migraine and ipsilateral trochleodynia with relief of migraine after successful treatment of trochleodynia. This disorder has been interpreted as "cluster-tic syndrome" or "seizure-triggered migraine". Trochlear Migraine is unrecognized and rarely described in childhood. The aim of this study is to review the few cases of Trochlear Migraine reported in the literature in addition to the cases observed in our clinical experience. In particular, our cases showed recurrent attacks of severe and pulsating headache associated with nausea, vomiting, phonophobia, photophobia, and strict trochlear localization of pain. They often presented with alternating side attacks. Therefore, we suggest that the term "Trochlear Migraine" should be reserved for clinical migraine attacks strictly localized in the trochlear region, and we assume that the excessive increase in descriptions of new primary headache syndromes, according to the International Classification of Headache Disorders, can be probably be ascribed to the common physiopathological mechanisms characterizing these forms of migraine.

Phenotype of Cluster Headache: Clinical Variability, Persisting Pain Between Attacks, and Comorbidities-An Observational Cohort Study in 825 Patients.

INTRODUCTION: Cluster headaches can occur with considerable clinical variability. The inter- and intra-individual variability could contribute to the fact that the clinical headache phenotype is not captured by too strict diagnostic criteria, and that the diagnosis and the effective therapy are thereby delayed. The aim of the study was to analyze the severity and extent of the clinical symptoms of episodic and chronic cluster headaches with regard to their variability and to compare them with the requirements of the International Classification of Headache Disorders 3rd edition (ICHD-3) diagnostic criteria. METHODS: The study was carried out as a cross-sectional analysis of 825 patients who had been diagnosed with cluster headaches by their physician. Using an online questionnaire, standardized questions on sociodemographic variables, clinical features of the cluster headache according to ICHD-3, and accompanying clinical symptoms were recorded. RESULTS: The majority of patients with cluster headaches have clinical features that are mapped by the diagnostic criteria of ICHD-3. However, due to the variability of the symptoms, there is a significant proportion of clinical phenotypes that are not captured by the ICHD-3 criteria for cluster headaches. In addition, change in the side of the pain between the cluster episodes, pain location, as well as persisting pain between the attacks is not addressed in the ICHD-3 criteria. In the foreground of the comorbidities are psychological consequences in the form of depression, sleep disorders, and anxiety. CONCLUSIONS: The variability of the phenotype of cluster headaches can preclude some patients from receiving an appropriate diagnosis and effective therapy if the diagnostic criteria applied are too strict. The occurrence of persisting pain between attacks should also be diagnostically evaluated due to its high prevalence and severity as well as psychological strain. When treating patients with cluster headaches, accompanying psychological illnesses should carefully be taken into account.

Cyclic Vomiting Syndrome in Infants and Children: A Clinical Follow-Up Study.

BACKGROUND: Cyclic vomiting syndrome is characterized by recurrent vomiting that is associated with increased adrenocorticotropic hormone and antidiuretic hormone levels during cyclic vomiting syndrome attacks. However, both prognosis and treatment remain unclear. We therefore evaluated the clinical features, prognosis, and effectiveness of the prophylaxis of cyclic vomiting syndrome as well as the relationship between symptoms and adrenocorticotropic hormone/antidiuretic hormone levels. METHODS: We included 31 patients with cyclic vomiting syndrome who were admitted to Teikyo University between 1996 and 2008. All patients were diagnosed with cyclic vomiting syndrome based on the criteria of the second edition of the International Headache Classification. The patients (25 of 31) were followed until 2013. RESULTS: The median overall duration of the disorder was 66 (3-179) months. Follow-up was completed for 25 patients with cyclic vomiting syndrome, of whom 44% (n = 11) developed migraine. Valproic acid, valproic acid with phenobarbital, phenobarbital, and amitriptyline were effective in nine, four, three, and one patients, respectively. Abnormally high adrenocorticotropic hormone (n = 17) and antidiuretic hormone (n = 18) levels were found among the 25 patients for whom follow-up data were available. The following correlations were significant: attack duration and adrenocorticotropic hormone levels (correlation coefficient: 0.5153, P = 0.0084) and attack duration and antidiuretic hormone levels (correlation coefficient: 0.5666, P = 0.0031). Antidiuretic hormone levels in patients with bilious vomiting were higher than in those without bilious vomiting (P = 0.048). CONCLUSIONS: Most patients with cyclic vomiting syndrome recovered completely and benefited from prophylactic therapy, although half of them developed migraines.

Αn uncommon coexistence of primary sexual, cough and exercise headaches: the first three cases from Greece.

BACKGROUND: The "other primary headaches" encompasses a group of uncommon but distinct headache disorders. The coexistence of their subforms such as primary sexual and exercise headache is not a new phenomenon, but in association with cough headache is rather uncommon. Report of cases: We report three cases with a rare coexistence of primary cough, exercise and associated with sexual activity headache. Indomethacin was effective in all patients. The leading pathophysiological explanation involves a rapid rise in intra-abdominal pressure exertional factors or an inappropriate reaction in the cerebral vasculature. CONCLUSIONS: Further studies are needed to confirm a common pathogenic mechanism in these patients. Τhe coexistence of these headaches needs to be taken into account in the final classification that is expected to be available in 2016. Hippokratia 2015; 19 (4): 369-371.

Headaches of otolaryngological interest: current status while awaiting revision of classification. Practical considerations and expectations.

In 1988, diagnostic criteria for headaches were drawn up by the International Headache Society (IHS) and is divided into headaches, cranial neuralgias and facial pain. The 2(nd) edition of the International Classification of Headache Disorders (ICHD) was produced in 2004, and still provides a dynamic and useful instrument for clinical practice. We have examined the current IHC, which comprises 14 groups. The first four cover primary headaches, with "benign paroxysmal vertigo of childhood" being the forms of migraine of interest to otolaryngologists; groups 5 to 12 classify "secondary headaches"; group 11 is formed of "headache or facial pain attributed to disorder of cranium, neck, eyes, ears, nose, sinuses, teeth, mouth or other facial or cranial structures"; group 13, consisting of "cranial neuralgias and central causes of facial pain" is also of relevance to otolaryngology. Neither the current classification system nor the original one has a satisfactory collocation for migraineassociated vertigo. Another critical point of the classification concerns cranio-facial pain syndromes such as Sluder's neuralgia, previously included in the 1988 classification among cluster headaches, and now included in the section on "cranial neuralgias and central causes of facial pain", even though Sluder's neuralgia has not been adequately validated. As we have highlighted in our studies, there are considerable similarities between Sluder's syndrome and cluster headaches. The main features distinguishing the two are the trend to cluster over time, found only in cluster headaches, and the distribution of pain, with greater nasal manifestations in the case of Sluder's syndrome. We believe that it is better and clearer, particularly on the basis of our clinical experience and published studies, to include this nosological entity, which is clearly distinct from an otolaryngological point of view, as a variant of cluster headache. We agree with experts in the field of headaches, such as Olesen and Nappi who contributed to previous classifications, on the need for a revised classification, particularly with regards to secondary headaches. According to the current Committee on headaches, the updated version of the classification, presently under study, is due to be published soon; it is our hope that this revised version will take into account some of the above considerations.
