Primary headache disorders are frequently encountered in the pediatric population. The therapeutic approach consists of a multimodal program, including lifestyle modification, psychotherapeutic intervention, pharmacotherapy, and complementary measures. This systematic review focuses on the pharmacotherapy of pediatric migraine and tension-type headache (TTH). ⋯ This review does not grade the drugs hierarchically because the complex profiles of many agents differ only slightly or even overlap. However, a detailed expert opinion is provided. On the basis of the outlined facts, the team of physician, patient, and parents has to decide on the most appropriate regimen for the individual situation in the sense of personalized medicine.

Review Comparative Study
Primary versus secondary headache in children: a frequent diagnostic challenge in clinical routine.
A sensitive and specific triage of patients with primary or secondary headache is a major concern in evaluating pediatric headache patients. History and physical examination are the major tools for differentiating primary headache disorders from symptomatic headaches caused by defined pathologies. If the criteria of the International Headache Society for a primary headache disorder are met, no further investigations are necessary. ⋯ Offering neuroimaging implicates the important issues of incidental findings and of "false reassurance." These risks should be discussed with patients and parents before the investigation. In any pediatric headache patient, regular clinical reevaluations should be warranted, even if neuroimaging is normal. The value of clinical follow-up examinations for a reasonable and reliable assessment of the patients cannot be overestimated.

Case Reports
Hemimegalencephaly associated with congenital infiltrating lipomatosis of the face: a case report.
Hemimegalencephaly (HME) is a rare congenital malformation of the brain, grossly characterized by enlargement and overdevelopment of one cerebral hemisphere. We describe a 16-month-old patient with facial asymmetry caused by congenital infiltrating lipomatosis of the face (CILF) associated with ipsilateral HME. ⋯ MRI also demonstrates the involvement of intracranial structures outside the affected cerebral hemisphere, such as brain stem, cerebellum, cranial nerves, and blood vessels. In our patient, computed tomography of the brain provided detailed information on osseous hypertrophy and skull-base foramina enlargement.

Febrile infection-related epilepsy syndrome (FIRES) is a severe postinfectious epileptic encephalopathy in previously healthy children and has three phases: the initial phase with a simple febrile infection, a few days later the acute phase characterized by a peracute onset of highly recurrent seizures or refractory status epilepticus often with no more fever and generally without additional neurological features (the classical pure seizure phenotype), and last, the chronic phase with a drug-resistant epilepsy and neuropsychological impairments. FIRES seems to be sporadic and very rare: we estimated the annual incidence in children and adolescents by a prospective hospital-based German-wide surveillance as 1 in 1,000,000. Because of the preceding infection and lacking evidence of infectious encephalitis, an immune-mediated pathomechanism and, therefore, a response to immunotherapies may be involved. ⋯ Moreover, steroids, immunoglobulins, and plasmapheresis had no clear effect in the seven patients receiving immunotherapy. The failure of antibody-detection against the known neuronal antigens as well as the ineffectiveness of immunotherapy questions a role for autoantibodies in the epileptogenesis of classical FIRES. As we discuss, other underlying causes need to be considered including the possibility of a mitochondrial encephalopathy.

We present a case study of an 11-year-old boy with Bannayan-Riley-Ruvalcaba syndrome (BRRS) with macrocephaly, lipomatosis, and penile freckles. BRRS was confirmed by a germline mutation in the phosphatase and tensin homolog (PTEN) gene. Repeated spinal imaging demonstrated an extensive progressive spinal epidural lipomatosis, compressing and dislocating the dural sac, so far without neurological deficits. Patients with BRRS are probably a risk for progressive spinal epidural lipomatosis and should be carefully monitored by neurological examinations and eventually neuroimaging follow-up studies.
