Childhood Headache Syndromes(Part I)
Headache is one of the most common reason that children are referred to the Pediatric Neurology Services. It is said that ten percent of children aged 5 to 15 years have migraine. Subsequently, it is essential for clinician to have a through, comprehensive and systematic approach to the evaluation and management of the child or adolescent who complain of headache.This writing aims to explore the symptoms of headache, its epidemiology, classification, appropriate evaluation, differential diagnosis and management.Headaches are divided into primary and secondary categories. Migraine and tension type headaches are prototype of primary headaches without underlying pathology. On the other hand, the type of headache which stems from organic diseases such as: brain tumor, increased intracranial pressure, systemic disease, drug toxicity or Ear Nose and Throat problems are considered secondary. On the whole, the majority of children with primary headache have two patterns of headache. One is a chronic low-grade and the other is an intermittent disabling headache. The cause of the former is either caffeine or analgesic abuse, and the latter is predominantly migraine. Traditionally, if a child presents himself with chief complain of headache, care taker physician begins with history taking followed by thorough physical and neurological examinations. In the majority of the cases, this initial process leads to a diagnosis or indicate the need for further testing. Once the diagnosis is made, a management program can be put into place.Key words: Headaches, Child, Children, Migraine.

Intractable Epilepsy in Children
ObjectiveEpilepsy is a common disorder affecting approximately 1% of the population. It is estimated that about 20- 30% of the patients become refractory to proper medical therapies. Such cases are often termed intractable. Intractable epilepsy (IE) is a serious condition in children, leading to significant impairment in quality of life, as well as behavioral and psychiatric problems.In this review, we tried to define intractability, mention the causes of intractable epilepsy and its predictive factors in children, and outline the management and various treatments of intractable epilepsy.
Introducing PACT Model of Transformative Persuasion: Re-emergence of Learning Approach to Persuasive Communications
The learning approach to persuasion was considered obsolete following the emergence of new paradigms such as cognitive and constructive approaches. However, according to the evolutions of learning theories and especially the re-emergence of the connectivism paradigm, mainly due to what new technologies have provided, the learning approach to persuasion seems to have reappeared as a powerful approach that has a lot to offer yet. Based on research conducted on transformative learning patterns and algorithms, this paper investigates: i) the applicability of using the patterns and algorithms as well as techniques developed in the transformative learning approach for transformative persuasion, ii) how media can be used in the transformation process. The components of a persuasive transformation model, the factors involved, and major elements of each factor are extracted by constructivist grounded theory (CGT), which is used for theory building, accumulating knowledge and experiences of scholars, practitioners, and experts in adult learning. We show how media can use these factors and elements and notions and techniques developed in transformative learning for the persuasive transformation of their respective audience. Borrowing the concepts of transformative learning concerning the states of mind of the adult students in different stages of the transformation process, we suggest how media can appropriately act in each stage to facilitate a transformation through persuasion
Approach to patients with neurometabolic diseases who show characteristic signs and symptoms
AbstractNeurometabolic disorders are hereditary conditions mainly affect the function of the brain and the nervous system. The prevalence of these disorders is 1 in 1000 live births. Such disorders, at different ages could manifest as sepsis, hypoglycemia, and other neurologic disorders. Having similar manifestations leads to delayed diagnosis of neurometabolic disorders. A number of neurometabolic disorders have known treatments; however, to prevent long‑term complications the key factors are early diagnosis and treatment. Although a large number of neurometabolic diseases have no treatment or cure, the correct and on‑time diagnosis before death is important for parents to have plans for prenatal diagnosis. Different diagnostic procedures could be offered to parents, enzymatic procedures and determining metabolites in plasma, urine, and CSF, and molecular genetic diagnosis. Molecular genetic diagnostic procedures are expensive and could not be offered to all parents. Therefore, we aimed to design algorithms to diagnose neurometabolic disorders according to some frequent and characteristic signs and symptoms. By designing these algorithms and using them properly, we could offer diagnostic enzymatic panels. These enzymatic panels are inexpensive, therefore, could reduce the financial burden on the parents. Also, having an early diagnosis according to these panels could lead to offering more accurate and less expensive molecular genetic tests
Plasma Pyridoxal 5´-Phosphate Level in Children with Intractable and Controlled Epilepsy
How to Cite This Article: Pirzadeh Z, Ghofrani M, Mollamohammadi M. Plasma Pyridoxal 5´-Phosphate Level in Children with Intractable and Controlled Epilepsy. Iran J Child Neurol. Spring 2017; 11(2):31-36. AbstractObjectiveIntractable epilepsy is a serious neurologic problem with different etiologies. Decreased levels of pyridoxal phosphate in cerebral spinal fluid of patients with intractable epilepsy due to pyridoxine dependency epilepsy are reported. The aim of this study was to compare plasma pyridoxal 5´-phosphate level in patients with intractable and controlled epilepsy.Materials & Methods This cross- sectional analytic study included 66 epileptic children, 33 patients with controlled and 33 patients with intractable epilepsy, after neonatal period up to 15 yr old of age. Thirty-three patients with intractable epilepsy (10- 162 months) and 33 patients with controlled epilepsy (14-173 months) were enrolled. The study was conducted in Pediatric Neurology Clinic of Mofid Children Hospital, Tehran, Iran from January 2010 to December 2010. Patients’ clinical manifestations, laboratory and neuroimaging findings were collected. Non-fasting plasma 5´- pyridoxal phosphate levels of these subjects were assessed by high-pressure liquid chromatography.Results Mean plasma 5´- pyridoxal phosphate level (PLP) in patients with controlled epilepsy was 76.78±37.24 (nmol/l) (15.5-232.4). In patients with intractable epilepsy, mean plasma 5´- pyridoxal phosphate was 98.67± 80.58 (25.5- 393) nmol/l. There was no statistically significant difference between plasma pyridoxal phosphate levels of these two groups (P═0.430).Conclusion Pyridoxine dependent epilepsy is under diagnosed because it is manifested by various types of seizures. Plasma pyridoxal phosphate levels did not differ in our patients with intractable or controlled epilepsy. If PDE is suspected on clinical basis, molecular investigation of ALDH7A1 mutations, as feasible test, until PDE biomarkers becomes available is recommended. References1.Cown LD.
