Objetivo O objetivo deste estudo foi avaliar prospectivamente os critérios diagnósticos da Classificação Internacional das Cefaleias 3 beta (CIC-3) de enxaqueca em crianças e adolescentes. Métodos 150 diários de dor foram analisados durante a consulta inicial. A duração dos episódios de enxaqueca foram divididos em dois grupos: Grupo I, para episódios com duração > 2 horas, e Grupo II, para os episódios < 2 horas. Os dois grupos foram comparados estatisticamente pelo teste exato de Fisher (p < 0,05). Resultados Neste estudo, 51 (34%) pacientes eram do sexo masculino e 99 (66%) eram do sexo feminino, com idade entre 7-15 anos. O teste exato de Fisher demonstrou que a CIC-3 beta teve sensibilidade de 58% para o diagnóstico do Grupo I e 94% para o diagnóstico do Grupo II (p < 0,001). Conclusão A atual classificação CIC-3 beta melhora e avança diagnóstico de enxaqueca em crianças e adolescentes; no entanto, mais pesquisas são necessárias para identificar as características adicionais de cefaléia nessa faixa etária.

Objective The objective of this study was to prospectively evaluate the International Classification of Headache Disorders I (ICHD-I) diagnostic criteria for migraine in children and adolescents. Methods 150 pain diaries were analyzed during an initial consultation. The duration of migraine headache attacks were divided into 2 groups: Group I, for attacks lasting > 2 hours, and Group II, for attacks lasting < 2 hours.The two groups were statistically compared using Fisher’s exact test (p < 0.05). Results In this study, 51(34%) subjects were male and 99 (66%) were female, aged 7–15 years. Fisher’s exact test demonstrated that the ICHD-3 beta had a 58% sensitivity for Group I diagnoses and a 94% sensitivity for Group II diagnoses (p < 0.001). Conclusion The current ICHD-3 beta classification improves and advances migraine diagnosis in children and adolescents; however, more research is needed to identify additional characteristics of headache in this age group.

ABSTRACT PURPOSE: To develop an experimental model of neurocysticercosis-induced hydrocephalus METHODS: There were used 17 rats. Ten animals were inoculated with Taenia crassiceps cysts into the subarachnoid. Five animals were injected with 0.1ml of 25% kaolin (a standard solution for the development of experimental hydrocephalus) and two animals were injected with saline. Magnetic resonance imaging (MRI) was used to evaluate enlargement of the ventricles after one or three months of inoculation. Volumetric study was used to quantify the ventricle enlargement. RESULTS: Seven of the 10 animals in the cyst group developed hydrocephalus, two of them within one month and five within three months after inoculation. Three of the five animals in the kaolin group had hydrocephalus and none in the saline group. Ventricle volumes were significantly higher in the 3-months MRI cyst subgroup than in the 1-month cyst subgroup. Differences between cyst subgroups and kaolin group did not reach statistical significance. CONCLUSION: The developed model may reproduce the human condition of neurocysticercosis-related hydrocephalus, which exhibits a slowly progressive chronic course.

A Sacroileíte pode ser responsável por até 40% dos casos de dor lombar crônica.Objetivo Análise da eficácia da denervação por radiofrequência na articulação sacro-ilíaca em seis, doze e dezoito meses.Método Trinta e dois pacientes com diagnóstico de sacroileíte foram incluídos em estudo prospectivo. O prognóstico primário foi avaliado pela escala visual analógico (NRS). O prognóstico secundário foi avaliado pela escala de impressão global de mudança pelo paciente (PGIC).Resultados Melhora a curto prazo da dor foi observada, com redução media na NRS de 7,7 ± 1,8 para 2,8 ± 1,2 após 1 mês e para 3,1 ± 1,9 em 6 meses do procedimento (p < 0,001). Após 12 e 18 meses, o NRS manteve-se 3,4 ± 2,1 e 4,0 ± 2,7, respectivamente.Conclusão A denervação da articulação sacro-ilíaca por radiofrequência pode reduzir significativamente a dor em pacientes com sacroileíte.

Sacroiliac joint (SIJ) pain is responsible for up to 40% of all cases of lumbar back pain.Objective Report the long-term efficacy of radiofrequency denervation for sacroiliac joint pain at six, twelve and eighteen months.Method Third-two adults’ patients with sacroiliac join pain diagnosis were included for a prospective study. Primary outcome measure was pain intensity on the Numeric Rating Scale (NRS). Secondary outcome measure was Patient Global Impression of Change Scale (PGIC).Results Short-term pain relief was observed, with the mean NRS pain score decreasing from 7.7 ± 1.8 at baseline to 2.8 ± 1.2 at one month and to 3.1 ± 1.9 at six months post-procedure (p < 0.001). Long-term pain relief was sustained at twelve and eighteen months post-procedure, with NRS pain remaining at 3.4 ± 2.1 and 4.0 ± 2.7, respectively.Conclusion Radiofrequency denervation of the SIJ can significantly reduce pain in selected patients with sacroiliac syndrome.

Relatamos um caso de aneurisma da bifurcação da artéria carótida interna, cuja ruptura se deu para dentro de cisto de aracnóide da fissura silviana. Em revisão da literatura apenas 3 casos foram descritos. Discutimos ainda os aspectos clínicos atípicos do caso, as características dos achados cirúrgicos e uma correlação etiopatogênica entre as duas patologias.

We report a case of a carotid artery bifurcation aneurysm which ruptured into a silvian fissure arachnoid cyst. In the review of the literature, only three cases were before reported. We discuss about uncommom clinical findings, the surgical aspects and the associations among the lesions.
