Osmophobia as an early marker of migraine: a follow-up study in juvenile patients.

Background: Osmophobia is frequent in children with migraine (20–35%) but can also occur in up to 14% of cases with tension-type headache (TTH). So far, the prognostic role of this symptom in children with primary headaches has never been evaluated. Methods: A longitudinal prospective study was conducted on 90 young patients with TTH (37 with osmophobia, 53 without osmophobia). We evaluated whether osmophobia could predict the diagnosis transformation from TTH to migraine after a 3-year follow-up. Results and Discussion: In our cases the rate of diagnosis change was significantly greater in cases with osmophobia (62%) than in those without (23%). Osmophobia persisted at a 3-year follow-up in the majority of our cases (85%) and it was found to be one of the major predictors for the development of migraine; other predictors of evolution to migraine were phonophobia, a probable rather than certain diagnosis of TTH and olfactory triggers (p < 0.05). Conclusion: Our data confirm that osmophobia has an important diagnostic and prognostic role in children with primary headaches and should be systematically investigated at diagnosis and during follow-up.

Osmophobia in migraine classification: A multicentre study in juvenile patients

Aims: This study was planned to investigate the diagnostic utility of osmophobia as criterion for migraine without aura (MO) as proposed in the Appendix (A1.1) of the International Classification of Headache Disorders (ICHD-II, 2004). Methods: We analysed 1020 patients presenting at 10 Italian juvenile headache centres, 622 affected by migraine (M) and 328 by tension-type headache (TTH); 70 were affected by headache not elsewhere classified (NEC) in ICHD-II. By using a semi-structured questionnaire, the prevalence of osmophobia was 26.9%, significantly higher in M than TTH patients (34.6% vs 14.3%). Results: Osmophobia was correlated with: (i) family history of M and osmophobia; and (ii) other accompanying symptoms of M. By applying these ‘new’ criteria, we found an agreement with the current criteria for the diagnosis of migraine without aura (MO) in 96.2% of cases; 54.3% of previously unclassifiable patients received a ‘new’ diagnosis. Conclusions: In conclusion, this study demonstrates that this new approach, proposed in the Appendix (A1.1), appears easy to apply and should improve the diagnostic standard of ICHD-II in young patients too.

The pharmacological treatment of migraine in children and adolescents: an overview

The appropriate treatment of migraine requires an individually tailored approach and is based on bio-behavioral, nonpharmacological and pharmacological methods. The available data in the pertinent literature on pharmacologic approaches are few and contradictory. Drug approaches for migraine attack include acetaminophen, NSAIDs and triptans. Acetaminophen and ibuprofen are often effective, but some migraine attacks may be refractory. The triptans can be a useful therapeutic option in adolescents. The literature data on prophylaxis are conflicting: flunarizine and topiramate are probably effective; for other drugs (including cyproheptadine, amitriptyline, divalproate and levetiracetam) there is insufficient evidence in children. The results from the use of propranolol are conflicting, whereas nimodipine and clonidine have been shown to be noneffective. Further studies are needed based on larger samples, multicenter trials, patient selection from primary care centers, and precise respect of current international diagnostic criteria. Moreover, new parameters of treatment efficacy should be considered.

Survey on treatments for primary headaches in 13 specialized juvenile Headache Centers: The first multicenter Italian study

AIM The purpose of this retrospective multicenter study was to evaluate the use and the self-perceived efficacy and tolerability of pharmacological and non-pharmacological treatments in children and adolescents with primary headaches. METHODS Study of a cohort of children and adolescents diagnosed with primary headache, consecutively referred to 13 juvenile Italian Headache Centers. An ad hoc questionnaire was used for clinical data collection. RESULTS Among 706 patients with primary headaches included in the study, 637 cases with a single type of headache (migraine 76% - with and without aura in 10% and 67% respectively; tension-type headache 24%) were selected (mean age at clinical interview: 12 years). Acetaminophen and non-steroidal anti-inflammatory drugs (in particular ibuprofen) were commonly used to treat attacks, by 76% and 46% of cases respectively. Triptans were used overall by 6% of migraineurs and by 13% of adolescents with migraine, with better efficacy than acetaminophen and non-steroidal anti-inflammatory drugs. Preventive drugs were used by 19% of migraineurs and by 3% of subjects with tension-type headache. In migraineurs, flunarizine was the most frequently used drug (18%), followed by antiepileptic drugs (7%) and pizotifen (6%), while cyproheptadine, propanolol and amitriptyline were rarely used. Pizotifen showed the best perceived efficacy and tolerability. Melatonin and nutraceuticals were used by 10% and 32% of subjects, respectively, both for migraine and tension-type headache, with good results in terms of perceived efficacy and tolerability. Non-pharmacological preventive treatments (i.e. relaxation techniques, biofeedback, cognitive-behavioral therapy, acupuncture) were used only by 10% of cases (migraine 9%, tension-type headache 15%). DISCUSSION Non-steroidal anti-inflammatory drugs, especially ibuprofen, should be preferred to acetaminophen for acute attacks of migraine or tension-type headache, because they were usually more effective and well tolerated. Triptans could be used more frequently as first or almost second choice for treating migraine attack in adolescents. Non-pharmacological preventive treatments are recommended by some pediatric guidelines as first-line interventions for primary headaches and their use should be implemented in clinical practice. Prospective multicenter studies based on larger series are warranted to better understand the best treatment strategies for young people with primary headaches.

Short lasting activity-related headaches with sudden onset in children: a case-based reasoning on classification and diagnosis.

BackgroundShort lasting headaches related to activity or cough are rare, particularly in childhood, and can be difficult to diagnose, especially in young children who are not able to describe their symptoms. In the literature there are few data on this topic in adults and the paediatric cases reported are even more rare.FindingsWe present the clinical history of a 7-year-old child and a 3-year-old child both diagnosed as having activity-related headaches, characterized by sudden onset of short lasting (few seconds) attacks, that were triggered by cough or exercise. There were no accompanying symptoms and the neurological examination was normal in both cases. Brain magnetic resonance imaging showed, in the first case, a cerebellar pilocytic astrocytoma and, in the second case, a Chiari 1 malformation. Both cases received an early diagnosis, were surgically treated and had a good prognosis at follow-up.ConclusionsWhen headache has a recent onset, it presents suddenly, and it is triggered by strain, even with normal neurological examination, neuroimaging is mandatory in order to exclude secondary headaches, especially in children.

Symptomatic and presumed symptomatic focal epilepsies in childhood: An observational, prospective multicentre study

To describe the clinical, neuropsychological, and psychopathologic features of a cohort of children with a new diagnosis of symptomatic or presumed symptomatic focal epilepsy at time of recruitment and through the first month. The selected population will be followed for 2–5 years after enrollment to investigate the epilepsy course and identify early predictors of drug resistance.

Spontaneous Involution of Diffuse Fibrous Dysplasia of Paranasal Sinuses

We report the case of a 25-year-old patient, diagnosed at age 10, with diffuse fibrous dysplasia of the paranasal sinuses, an extremely rare idiopathic condition. This diagnosis is possible only by cerebral computed tomography (CT), cerebral and anterior skull base magnetic resonance imaging (MRI), and histopathology. Surgical treatment is common. This boy had mild symptoms: moderate headache in the morning that did not affect his daily activity, and rhinitis, partially responsive to medication. The neurologic examination was abnormal. Radiographs, CT, and MRI showed a diffuse mass in the paranasal sinuses which had a histopathological diagnosis of fibrous dysplasias. The family refused to refer the patient to surgery. The boy has been monitored annually for 15 years. He has remained asymptomatic without headache since age 11, with normal, general and neurologic examinations. Serial MRIs showed a spontaneous partial involution of the mass.

P046. ADHD and headache: observational study of case series

Background Attention deficit and hyperactivity disorder (ADHD) and headache are two very common diseases in childhood and both of them have an important impact on quality of life and academic performance [1]. In the literature there are many studies on psychopathology in headache, but the relationship between headache and ADHD is considered in few of them [2]. Recent studies have reported possible neural pathways and pathophysiological mechanisms that may underlie this relationship [3].
