Introduction: Clear cell sarcoma (CCS) is a rare and aggressive soft tissue sarcoma. CCS is characterized by the translocation t(12;22) (q13;q12), involving the fusion of EWSR1 and ATF1 genes, and less frequently the fusion gene EWSR1-CREB1. Usually, CCSs are considered poorly responsive to conventional chemotherapy.

Angiofibroma is a non-encapsulated, highly vascular tumor that usually originates in the nasopharynx. Laryngeal cases of extranasopharyngeal angiofibroma (ENA) are a very rare pathology, especially in children. Only eight ENA laryngeal cases have been described in the literature, and only one of them is a pediatric case.

A sample of elementary school children (experimental group = 37; control group = 66), attending Portuguese schools, was assessed before and 6 months after the intervention on the program's key-dimensions: behavioral problems, social skills, and executive functioning. Based on parent and teacher reports, the results largely suggested that the intervention had no effect or, for some dimensions, even the existence of negative outcomes.

We compared the maculas of diabetic subjects without diabetic retinopathy with those of healthy subjects and correlated the findings with the clinical profiles of diabetic subjects.
Methods: One eye each of 30 patients with diabetes and 30 healthy individuals were examined.
Background: Solitary fibrous tumor is an unusual fibroblastic mesenchymal neoplasm typically described in the pleura. It may appear anywhere with a varied anatomic distribution and essentially it can develop from any soft tissue or visceral location. Its course is usually indolent and it rarely causes distant metastases, so it has a prolonged survival rate.

(1) Background: We analyzed, using PET-SCAN and cognitive tests, how growth hormone (GH) could act in the brain of an older woman, not deficient in GH, who showed mild cognitive alterations (MCI) and had a genotype of ApoE 4/3 and familial dyslipidemia. (2) Methods: After performing a first psychometric study (TAVEC verbal learning test), the metabolic activity of brain structures related to knowledge, memory, and behavior was analyzed using 18-F fluorodeoxyglucose PET-SCAN. The patient was then treated with GH (0.

The aim of this study was to evaluate the prevalence of MSD and its association with self-reported joint damage in dentists from São Paulo (Brazil).
Methods: This was a cross-sectional study performed from two self-administered questionnaires - the Nordic Musculoskeletal Questionnaire and the other containing demographic and occupational data - in 6072 dentists.
Introduction: Fibrous hamartoma of infancy is a rare soft tissue tumour that usually appears before 2 years of age, typically in the upper extremities of male infants.
Case Report: We report the case of a 2 year old boy with a large and rapidly growing tumour in the upper extremity.
Comments: We describe the case, its differential diagnosis and the immunhistological characteristics, and we discuss the non-aggressive surgical treatment, based on the benign behaviour of this tumour.
Importance: The Zika virus (ZIKV) might cause microcephaly and ophthalmoscopic findings in infants of mothers infected during pregnancy.
Objective: To assess and identify possible risk factors for ophthalmoscopic findings in infants born with microcephaly and a presumed clinical diagnosis of ZIKV intrauterine infection.
Design, Setting, And Participants: We conducted a cross-sectional study at the Altino Ventura Foundation in Recife, Brazil, that included 40 infants with microcephaly born in Pernambuco state, Brazil, between May and December 2015.
The aim of this study was to evaluate the influence of the physical assessment of different light-curing units from 55 dental offices on the irradiance and composite microhardness top/bottom ratio, and the influence of the radiometers for LED or QTH light sources on irradiance measurement. The irradiance of each light-curing unit was evaluated with two radiometers, either for LED or QTH light. A questionnaire regarding the type of source (LED or QTH), time of use, date of last maintenance and light-curing performance assessment applied.

Materials And Methods: A systematic search was carried out in Cochrane and PubMed databases. From the selected studies, the survival rates for porcelain and glass-ceramic veneers were extracted, as were complication rates of clinical outcomes: debonding, fracture/chipping, secondary caries, endodontic problems, severe marginal discoloration, and influence of incisal coverage and enamel/dentin preparation.
It is well known that the histology of normal pineal gland may resemble not only pineal tumors but also gliomas, owing to its cellularity which is much greater than that of normal white or gray matter. Our recent experience with a case in which part of a normal gland was submitted for intraoperative consultation, together with the scarcity of cytologic descriptions, led us to perform a cyto-histologic correlation study. In addition to the intraoperative case, we collected five pineal glands from consecutive adult autopsies.

Endocarditis is a type of infection that is common in internal medicine wards and in haemodialysis clinics. The location that is most affected are the heart valves. Herein, we report a case of an uncommon abscess, a sub-endothelial abscess between the transition of the superior vena cava and the right atrium.

Methods: Twenty two patients (24 eyes) were included. All patients underwent complete ophthalmological examination, applanation tonometry and AS-OCT at diagnosis and fifteen days after treatment.
This study evaluated the influence of specimen dimensions and storage medium and temperature on the flexural properties of one dental resin composite. The material utilized throughout the study was Clearfil AP-X. Eighty specimens were built with dimensions of either 10×2×2 mm or 25×2×2 mm, stored dry or in distilled water, at 25 or 37ºC, for 24 h.

Resin-based composite staining is a multifactoral phenomenon and can be caused by intrinsic and extrinsic factors. The purpose of this study was to compare staining, sorption and solubility of silorane resin-based and universal resin-based composites. Five different resin-based composites (4 Seasons, Charisma, Filtek Silorane, Filtek Supreme and Grandio) were tested.

Thirty-six specimens were prepared and immersed in water at 37°C for 24 hours. After polishing, specimen color was measured in a spectrophotometer Cintra 10 UV (Visible Spectrometer, GBC, Braeside, VIC, Australia).

Thirty sound human maxillary premolars were assigned to 3 groups: 1- sound/unprepared (control); 2- inlays and 3- overlays. The inlay cavity design was Class II MOD preparation with an occlusal width of 1/2 of the intercuspal distance.

The aim of this study was to assess the relation between the surface hardness of seven different commercial brands of resin composites (Charisma, Fill Magic, Master Fill, Natural Look, Opallis, Tetric Ceram, and Z250) and the different degrees of translucence (translucid, enamel and dentin). Vickers microhardness testing revealed significant differences among the groups.
