Abstract
Background: Age-related macular degeneration (AMD) is a multifactorial disease and one of the main causes of blindness in people over 50 years old. The etiology and pathophysiology of AMD are not well understood. The aim of this study was to investigate whether the rs1143627 variant allele of IL1B, which encodes Interleukin (IL)-1β, a key cytokine, mediates immune and inflammatory responses.Methods: A case-control study was conducted with 397 AMD patients and 402 controls in Brazil. IL1B genotyping was carried out with TaqMan® genotyping assay. Differences in IL1B allele frequencies and genotypes were evaluated between patients and controls and between wet and dry subgroups of AMD. Relationships between allele presence/genotype and disease risk are reported as odds ratios (ORs) with 95% confidence intervals (CIs).Results: Genotype proportions for the rs1143627 variant allele of IL1B were similar between AMD patients and controls (p = .21), with 84.38% of AMD patients and 79.60% of the controls carrying the variant allele. We observed a trend toward the variant allele being associated with AMD risk (OR = 1.38, 95% CI 0.95-2.03, p = .08), as well as a trend toward the variant allele being associated with increased risk for wet AMD in particular (OR = 1.23, 95% CI 0.96-1.56, p = .08).Conclusions: The rs1443627 variant was not associated with AMD risk in this Brazilian population sample. Larger studies are warranted to determine whether the trends observed in this study reflect a relationship between this variant and risk of AMD, especially wet AMD.

Abstract
INTRODUCTION Congenital infection by the Zika virus (ZIKV) is responsible for severe abnormalities in the development of the central nervous system. The aim of this study was to evaluate and compare the ability of computed tomography (CT) and magnetic resonance (MR) to detect patterns of involvement of the central nervous system in congenital ZIKV syndrome. METHODS We retrospectively analyzed CT and MR images from 34 patients with congenital ZIKV syndrome and evaluated the differences between the two methods in detecting alterations. RESULTS The predominant radiographic finding was a simplified gyral pattern, present in 97% of cases. The second most common finding was the presence of calcifications (94.1%), followed by ventriculomegaly (85.3%), dysgenesis of the corpus callosum (85.3%), craniofacial disproportion and redundant scalp (79.4%), complete opercular opening (79.4%), occipital prominence (44.1%), cerebellar hypoplasia (14.7%), and pontine hypoplasia (11.8%). The gyral pattern was extensively simplified in most cases, and calcifications were located predominantly at the cortical-subcortical junction. CT was able to better identify calcifications (94.1% × 88.2%), while MRI presented better spatial resolution for the characterization of gyral pattern (97% × 94.1%) and corpus callosum dysgenesis (85.3% × 79.4%). CONCLUSIONS Although congenital ZIKV syndrome does not present pathognomonic neuroimaging findings, some aspects, such as calcifications at the cortical-subcortical junction, especially when associated with compatible clinical and laboratory findings, are suggestive of intrauterine ZIKV infection.

Abstract
The introduction of functional endoscopic sinus surgery in the 1980s brought
about a drastic change in the treatment of patients with rhinosinusitis,
improving quality of life through the removal of pathological processes or
anatomical variations that obstruct the drainage pathways of the paranasal
sinuses. However, despite the routine use of computed tomography in the
anatomical evaluation of the paranasal sinuses, most radiological reports still
do not provide sufficient information to guide the surgical planning. The
objective of this pictorial essay was to demonstrate, through computed
tomography, the main anatomical variations of the paranasal sinuses, the
recognition of which is fundamental for preoperative planning, in order to avoid
treatment failure and iatrogenic complications.

Abstract
Hearing disorders are usually unilateral and are more common in women. They can be congenital or acquired, and hearing loss is categorized as sensorineural, conductive, or mixed. The onset of hearing loss can be progressive or sudden, and it is a common reason for seeking medical attention. In this context, computed tomography and magnetic resonance imaging have assumed critical roles in the search for an etiological diagnosis and in guiding the therapeutic approach. In this pictorial essay, we illustrate the common causes of hearing loss, discussing the possible differential diagnoses and highlighting the most relevant imaging findings.

Abstract
BACKGROUND AND OBJECTIVE White matter lesions are non-static brain lesions that have a prevalence rate up to 98% in the elderly population. Because they may be associated with several brain diseases, it is important that they are detected as soon as possible. Magnetic Resonance Imaging (MRI) provides three-dimensional data with the possibility to detect and emphasize contrast differences in soft tissues, providing rich information about the human soft tissue anatomy. However, the amount of data provided for these images is far too much for manual analysis/interpretation, representing a difficult and time-consuming task for specialists. This work presents a computational methodology capable of detecting regions of white matter lesions of the brain in MRI of FLAIR modality. The techniques highlighted in this methodology are SLIC0 clustering for candidate segmentation and convolutional neural networks for candidate classification. METHODS The methodology proposed here consists of four steps: (1) images acquisition, (2) images preprocessing, (3) candidates segmentation and (4) candidates classification. RESULTS The methodology was applied on 91 magnetic resonance images provided by DASA, and achieved an accuracy of 98.73%, specificity of 98.77% and sensitivity of 78.79% with 0.005 of false positives, without any false positives reduction technique, in detection of white matter lesion regions. CONCLUSIONS It is demonstrated the feasibility of the analysis of brain MRI using SLIC0 and convolutional neural network techniques to achieve success in detection of white matter lesions regions.

Abstract
Although infection with the Zika virus was first recognized in 1942, it received
little attention until 2007, when a true pandemic spread throughout Africa,
Asia, and the Americas. Since then, numerous forms of central nervous system
involvement have been described, mainly malformations related to congenital
infection. Although the neuroimaging findings in congenital Zika syndrome are
not pathognomonic, many are quite suggestive of the diagnosis, and radiologists
should be prepared to interpret such findings accordingly. The objective of this
article is to review the computed tomography and magnetic resonance imaging
findings in congenital Zika syndrome.
