Neurological disorders, especially PN, are common in our Brazilian cohort of IBD patients. They are diverse, multifactorial, and more common in women. Despite the mild phenotype in most cases, attention should be given by the general practitioner and gastroenterologist since they are frequently undiagnosed. Further studies are necessary to confirm these findings in populations with different genetic and nutritional backgrounds.

-The distinction of non-epileptic from epileptic events is difficult even for experienced neurologists. We retrospectively evaluated 59 dialeptic events from 27 patients admitted for video EEG monitoring to check whether heart rate (HR) analysis could help in differentiating dialeptic complex partial temporal lobe seizures (TLS) from dialeptic simple partial TLS, and non-epileptic dialeptic events. Baseline HR was increased in the simple partial TLS in comparison to complex partial TLS and non-epileptic groups (p<0.05). HR increase accompanied each individual dialeptic complex partial TLS (100% of the events, p<0.05) bur HR returned to baseline in the post-ictal phase. Ictal HR was not altered in the non-epileptic or simple partial TLS groups. Our findings suggest that ictal centrally mediated tachycardia is characteristic of dialeptic TLS (both tachycardia and bradycardia have been reported during TLS). This finding may be used as a criterion to distinguish dialeptic complex partial TLS from simple partial and non-epileptic dialeptic events.KEy WORdS: heart rate, dialeptic seizures, temporal lobe epilepsy, epileptic auras. a análise da freqüência cardíaca diferencia crises dialépticas parciais complexas de auras e crises não epilépticas RESUMO -A distinção entre eventos não epilépticos de epilépticos é difícil mesmo para neurologistas experientes. Analisamos 59 eventos dialéticos de 27 pacientes internados para monitorização por video-EEG para checar se a análise da frequência cardíaca (FC) poderia auxiliar na diferenciação de crises dialépticas parciais complexas de crises dialépticas parciais simples e eventos dialépticos não epilépticos. A freqüência cardíaca basal estava aumentada nos pacientes com crises parciais simples em comparação com o período basal dos grupos parcial complexa e não epiléptico (p<0,05). Houve aumento da freqüência cardíaca em cada crise dialéptica parcial complexa (100% dos eventos, p<0,05), mas a FC retornou aos níveis basais na fase pós-ictal. A FC ictal não foi alterada nos grupos de crises não epiléticas e nos pacientes com crises parciais simples. Nossos achados sugerem que a taquicardia ictal com mediação central é característica de crises parciais complexas dialépticas (tanto taquicardia quanto bradicardia têm sido relatados durante crises temporais parciais complexas). Tal achado poderá ser utilizado como critério para diferenciar crises dialép-ticas parciais complexas de crises dialépticas parciais simples e eventos dialépticos não epilépticos. PALAVRAS-CHAVE: frequência cardíaca, crises dialépticas, epilepsia do lobo temporal, auras epilépticas.

In the absence of intervention, the rate of vertical transmission of HIV can range from 15-45%. With the inclusion of antiretroviral drugs during pregnancy and the choice of delivery route this amounts to less than 2%. However ARV use during pregnancy has generated several questions regarding the adverse effects of the gestational and neonatal outcome. This study aims to analyze the risk factors for vertical transmission of HIV-1 seropositive pregnant women living in Rio Grande and the influence of the use of ARVs in pregnancy outcome. Among the 262 pregnant women studied the rate of vertical transmission of HIV was found to be 3.8%. Regarding the VT, there was a lower risk of transmission when antiretroviral drugs were used and prenatal care was conducted at the referral service. However, the use of ART did not influence the outcome of pregnancy. However, initiation of prenatal care after the first trimester had an influence on low birth weight, as well as performance of less than six visits increased the risk of prematurity. Therefore, the risk factors analyzed in this study appear to be related to the realization of inadequate pre-natal and maternal behavior.
