RESUMEN
Central nervous system (CNS) involvement in Henoch-Schonlein purpura (HSP) is rare but poses diagnostic difficulties. The aim of the study was to establish the frequency of CNS involvement in HSP, to analyze its clinical characteristics and do a literature review. Medical files of patients with HSP admitted at the Department of Pediatrics, Plovdiv, were studied retrospectively for a five-year period (2009-2013). Diagnosis was based on the American College of Rheumatology criteria. Out of 112 children with HSP 1 case (0.9%) had CNS involvement presenting as Posterior Reversible Encephalopathy Syndrome (PRES), which may be a result of CNS vasculitis or arterial hypertension. It was an 8-year-old girl with atypical HSP which started with abdominal pain requiring surgery. On the third day after the operation a transient macular rash and arterial hypertension appeared, followed by visual disturbances, hemiconvulsive epileptic seizures, postictal hemiparesis, and confusion. Head CT showed occipital hypodense lesions and MRT-T2 hyperintense lesion in the left occipital lobe. The patient experienced a second similar episode after 2 weeks when palpable purpura had also appeared. Neurological symptoms and MRI resolved completely. HSP can be an etiological factor for PRES in childhood. Although PRES is a rare complication of HSP, clinicians must be aware of it and avoid diagnostic and therapeutic delays.
RESUMEN
UNLABELLED: Migraine is common in pediatric neurology practice, while migraine variants are rare and pose diagnostic problems. OBJECTIVE: The aim was to establish the occurrence of migraine variants in pediatric neurology practice and among migraine, and to discuss their presentation. PATIENTS AND METHODS: The files of 2509 newly diagnosed patients, aged 0-18 years, treated as in- and out-patients in the Neuropediatric Ward at the Plovdiv Medical University Hospital between 2002 and 2006 were examined retrospectively. Migraine forms were diagnosed according to ICHD-II. Benign paroxysmal torticolis and alternating hemiplegia of childhood were also accepted as migraine variants according to proposed diagnostic criteria in the appendix of ICHD-II. Some specific forms like acute confusional migraine (ACM), Alice in wonderland syndrome (AWS), ophthalmoplegic migraine were also diagnosed although not included as migraine variants in the ICHD-II classification. RESULTS: 111 patients met diagnostic criteria for migraine. Patients with migraine variants comprised 24.3% of migrainous cases. Basilar type migraine was the most common (6.3% of all migrainous patients), followed by benign paroxysmal vertigo (5.4%), hemiplegic migraine (3.6%), ACM (2.7%), benign paroxysmal torticolis (2.7%), typical aura without headache (1.8%), abdominal migraine (1.8%), AWS (0.9%), ophthalmoplegic migraine (0.9%) and cyclical vomiting (0.9%). Alternating hemiplegia of childhood and retinal migraine was not found. Some patients either presented or were classified as different migraine variants. CONCLUSION: Basilar type migraine was the most common migraine variant. ACM and AWS should be regarded as distinct entities in the ICHD as migraine with complex aura. Benign paroxysmal torticollis also deserves its place as a migraine variant. Cases of ophthalmoplegic migraine with spontaneous remission and no cranial nerve enhancement on MRI should be considered as migraine form. Analyzing migraine variants will contribute to better awareness and adequate diagnosis.

AIM: To suggest diagnostic combinations of symptoms for migraine and tension type headache (TTH), and for differentiation of overlapping headache (classified as either migraine or TTH) through evaluation of the diagnostic value of combinations of characteristics included in the International Headache Society diagnostic criteria for migraine and TTH in children and adolescents. PATIENTS AND METHODS: The study comprised an epidemiological school-based study (412 of 1029 pupils with chronic/recurrent headache) and a clinical study conducted in the Pediatric Neurology Ward and outpatient clinic at Plovdiv Medical University Hospital (203 patients with chronic/recurrent headache). An inclusion criterion was at least two episodes of headache during the last year. Exclusion criteria were: headache occurring only during acute infections; withdrawal of informed consent. Headache was classified according to the International Classification of Headache Disorders 2nd edition (ICHD-II) The diagnostic value of all combinations of items in criteria C and D for migraine and TTH was measured by sensitivity, specificity, and odds ratio. RESULTS: The combination "unilateral location, severe intensity, aggravation by physical activity" had 100% specificity for migraine. The combination "bilateral location, pressing-tightening quality, mild intensity, no aggravation by physical activity" had 100% specificity for TTH. The combinations: "migrainous location, severe intensity, aggravation by physical activity", "severe intensity, nausea", "pulsating quality, nausea", "pulsating quality, migrainous location, aggravation by physical activity" seemed to pose the greatest risk for developing migraine. These combinations--"no nausea, no photophobia", "bilateral location, mild intensity and either no aggravation by physical activity or pressing-tightening quality, or no nausea or no photophobia" increased the most the TTH risk. Using these combinations as additional criteria for overlapping headache we classified 50% of overlapping headache as TTH and 8.3% as migraine. CONCLUSIONS: Some combinations of symptoms clarify the diagnosis of migraine and TTH. More than 50% of overlapping headache could be differentiated as TTH or MWA by the proposed combinations.
