Infecção por Shigella no Período Neonatal
Rodrigues, F.; Mimoso, G.; Ramos, L.; Negrão, F.; Lemos, C.; Ramos, C.A infecção por Shigella no período neonatal é muito rara, sendo o diagnóstico frequentemente difícil pela diversidade e inespecificidade dos sintomas.Apresenta-se um caso de infecção por Shigella no período neonatal, que se apresentou com letargia, recusa alimentar e distensão abdominal, seguidos mais tarde de diarreia com sangue.Apesar de arrastada, teve boa evolução.
Fenilcetonúria Materna — A Propósito Dum Caso Clínico
Ferreira, R.; Nunes, C.; Silva, I. S.; Lemos, C.; Ramos, C.Descreve-se o caso de um recém-nascido com atraso de crescimento intra-uterino e microcefalia. cuja mãe tinha fenilcetonúria (PKU), não controlada durante a gravidez. Chama-se a atenção para o possível aparecimento de futuros casos, em fenilcetonúrias que tenham abandonado o tratamento dietético ou que tenham nascido antes do início do rastreio neonatal sistemático da PKU.
Monozygotic twin sisters discordant for familial hemiplegic migraine
Barros, J.; Barreto, R.; Brandão, A.; Domingos, J.; Damásio, J.; Ramos, C.; Lemos, C.; Sequeiros, J.; Alonso, I.; Pereira-Monteiro, J.Background: The high concordance rate of migraine in monozygotic twin pairs has long been recognised. In the current study, we present a monozygotic twin pair discordant for familial hemiplegic migraine (FHM). Case presentations: We evaluated 12 adult family members in 2012. The twin pair was separately examined by neurologists at different time points. Mutation screening was performed for known FHM-related gen...
Interaction between γ-Aminobutyric Acid A Receptor Genes: New Evidence in Migra...
Quintas, M.; Neto, J.; Pereira-Monteiro, J.; Barros, J.; Sequeiros, J.; Sousa, A:; Alonso, I.; Lemos, C.Migraine is a common neurological episodic disorder with a female-to-male prevalence 3- to 4-fold higher, suggesting a possible X-linked genetic component. Our aims were to assess the role of common variants of gammaaminobutyric acid A receptor (GABAAR) genes, located in the X-chromosome, in migraine susceptibility and the possible interaction between them. An association study with 188 unrelated cases and 286 ...
Spatial memory impairments in a prediabetic rat model
Soares, E.; Prediger, R. D.; Nunes, S.; Castro, A. A.; Viana, S .D.; Lemos, C.; Souza, C. M. De; Agostinho, P.; Cunha, R. A.; Carvalho, E.Diabetes is associated with an increased risk for brain disorders, namely cognitive impairments associated with hippocampal dysfunction underlying diabetic encephalopathy. However, the impact of a prediabetic state on cognitive function is unknown. Therefore, we now investigated whether spatial learning and memory deficits and the underlying hippocampal dysfunction were already present in a prediabetic animal m...
Ventilação não invasiva com pressão positiva intermitente - experiência de 7 anos
Resende, C; Fonseca, M; Mesquita, J; Faria, D; Mimoso, G; Lemos, CIntroduction: Nasal intermittent positive pressure ventilation (NIPPV) is a non invasive ventilation method that combines the benefits of nasal continuous positive airway pressure (NCPAP) and the cycles of positive pressure. Objectives: Description of the NIPPV experience in a neonatal intensive care unit. Methods: A descriptive study of newborns ventilated with NIPPV, from January 2002 to December 2008. Were c...
Assessing risk factors for migraine: differences in gender transmission
Lemos, C.; Alonso, I.; Barros, J.; Sequeiros, J.; Pereira-Monteiro, J.; Mendonça, D.; Sousa, A.Abstract AIM: Our aim was to assess which specific factors are contributing to an increased risk of migraine in a group of 131 Portuguese families. METHODS: We studied 319 first-degree relatives, using a multilevel approach to account for the dependency among members from the same family. We included in the model relative's gender, the proband's gender and age-at-onset, to evaluate if any of these variables we...
A role for endothelin receptor type A in migraine without aura susceptibility? ...
Lemos, C.; Neto, J.; Pereira-Monteiro, J.; Mendonça, D.; Barros, J.; Sequeiros, J.; Alonso, I.; Sousa, A.Abstract BACKGROUND AND PURPOSE: Migraine is a common neurological disabling disorder, and anomalies of vascular function have been implied in its pathophysiology. Several findings point to a possible role of the endothelin receptor type A (EDNRA) in migraine. We aim to assess the involvement of endothelin receptor type A (EDNRA) in migraine susceptibility in a sample of Portuguese migraineurs. METHODS: Three...
BDNF and CGRP interaction: implications in migraine susceptibility
Lemos, C.; Mendonça, D.; Pereira-Monteiro, J.; Barros, J.; Sequeiros, J.; Alonso, I.; Sousa, A.Abstract OBJECTIVES: Migraine pathophysiology involves several pathways. Our aims were to explore a possible role of the brain-derived neurotrophic factor gene (BDNF) in migraine susceptibility; to study, for the first time, the calcitonin gene-related peptide gene (CGRP); and a possible interaction between the two. METHODS: Using a case-control approach, four tagging single nucleotide polymorphisms (SNPs) (r...
Evidence of syntaxin 1A involvement in migraine susceptibility: a Portuguese st...
Lemos, C.; Pereira-Monteiro, J.; Mendonça, D.; Ramos, E.; Barros, J.; Sequeiros, J.; Alonso, I.; Sousa, A.Abstract OBJECTIVE: To confirm syntaxin 1A as a risk factor for migraine, given that syntaxin 1A interacts with several factors in migraine pathophysiology. DESIGN: Case-control approach. SETTING: An outpatient clinic. PARTICIPANTS: In a sample of 188 migraineurs (111 without aura and 77 with aura) and 287 migraine-free controls, 3 tagging SNPs of STX1A (rs3793243, rs941298, and rs6951030) were analyzed. A b...
