Association between Elevated Iodine Intake and IQ among School Children in Port...

The goal of this work was to examine whether elevated iodine intake was associated with adverse effects on IQ among school-age children in Portugal. In a representative sample of children from the north of the country, IQ percentiles by age (assessed with Raven’s Colored Progressive Matrices) were dichotomized to <50 (“below-average” IQs) and ≥50. Morning urine iodine concentrations, corrected for creatinine, w...

Newborn Hearing Screening: 5 Years´ Results

In an average of 1000 healthy babies, up to 3 have sensorineural hearing loss ( but this incidence increases 20 to 40 babies if we take into account the newborns’ high risk factors. Newborn hearing screening is essential to detect the total of babies with hearing loss 35 dB If hearing loss is present, it will allow an early detection (before 2 months of age) and an adequate intervention re(h) abilitation before...

Auditory Neuropathy Spectrum Disorder - 2 Different But Successfull Pediatric C...

Auditory Neuropathy Spectrum Disorder ( is a disorder characterized by disruption of the temporal coding of acoustic signals in auditory fibers with consequent impairment of auditory perceptions dependent on temporal cues ANSD is a rare condition, associated with several risk factors and its diagnosis and management are challenging Objective To compare 2 pediatric cases of ANSD and analyze its rehabilitation Ma...

Attenuation of the diffuse noxious inhibitory controls in chronic joint inflamm...

The noradrenergic system is paramount for controlling pain and emotions. We aimed at understanding the descending noradrenergic modulatory mechanisms in joint inflammatory pain and its correlation with the diffuse noxious inhibitory controls (DNICs) and with the onset of anxiodepressive behaviours. In the complete Freund’s adjuvant rat model of Monoarthritis, nociceptive behaviors, DNICs, and anxiodepressive-li...

Current Trends and Perceptions of the Portuguese Gynecology Experts on Hormonal...

Overview and Aims: Intrauterine systems (IUS) are one of the most effective forms of long acting reversible birth control, with low failure rates and high continuity and satisfaction rates. Still, they account for a small proportion of contraception use, which may be due to several myths and misperceptions. With this study, we aimed to assess Portuguese experts’ perceptions on potential benefits and fears that ...

Role of Spinal Cord α 2-Adrenoreceptors in Noradrenergic Inhibition of Nocicept...

Chemotherapy-induced peripheral neuropathy (CIPN) is a problem during cancer treatment and for cancer survivors but the central mechanisms underlying CIPN remain understudied. This study aims to determine if CIPN is associated with alterations of noradrenergic modulation of nociceptive transmission at the spinal cord. CIPN was induced in male Wistar rats by paclitaxel injections. One month after CIPN induction,...

Direct Gaze Partially Overcomes Hemispatial Neglect and Captures Spatial Attention

Direct gaze has been shown to be a particularly important social cue, being preferentially processed even when unconsciously perceived. Results from several visual search tasks further suggest that direct gaze modulates attention, showing a faster orientation to faces perceived as looking toward us. The present study aimed to analyze putative modulation of spatial attention by eye gaze direction in patients wit...

Neuropathic pain induced alterations in the opioidergic modulation of a descend...

Opioids play a major role at descending pain modulation but the effects of neuropathic pain on the brain opioidergic system remain understudied. Since descending facilitation is enhanced during neuropathic pain, we studied the opioidergic modulation of the dorsal reticular nucleus (DRt), a medullary pain facilitatory area, in the spared nerve injury (SNI) model of neuropathic pain. We first performed a series o...
