1. Technical Note: First Use of Endonasal Confocal Laser Endomicroscopy – Feasibility and Proof of Concept
Abstract Introduction Probe-based confocal laser endomicroscopy (p-CLE) is a method for real-time in vivo visualization of mucosal changes on a cellular level. Due to the size of the endoscopes, it was mainly used in the gastrointestinal tract so far. First investigations on head and neck carcinoma described the oropharyngeal application. The further miniat

2. Children's discomfort in assessments using different methods for approximal caries detection
Because discomfort caused by different approximal caries detection methods can influence their performance, the assessment of this discomfort is important. Thus, this study aimed to evaluate the discomfort reported by children after the use of different diagnostic methods to detect approximal caries lesions in primary teeth: visual inspection, bitewing radio

3. Valor preditivo da topografia de disco óptico para o desenvolvimento de glaucoma / Predictive value of optic disc topography for the development of glaucoma
Purpose: To evaluate the ability of baseline confocal scanning laser ophthalmoscopy, using the Heidelberg Retina Tomograph (HRT), in predicting the development of progression in patients suspected of having glaucoma. In addition, the study also aimed to compare the predictive abilities of the glaucoma probability score (GPS) with those of the Moorfields regr

4. Espectroscopia de fluorescência para detecção de lesões potencialmente malignas e carcinoma epidermóide da cavidade oral : estudo prospectivo / Fluorescence spectroscopy for detection of premalignant lesions and squamous cell carcinoma of the oral cavity : prospective study
Oral cancer is a public health problem with high incidence in the Brazilian population. The affected patient usually presents for clinical investigation, with advanced stage disease, the consequence of this delay is a reduction in survival rates. Given this, its essential to detect oral cancer in early stages. Fluorescence spectroscopy is a non-invasive di

5. Tecnologias de exame da carie dentaria : o desafio de seu uso sob diferentes criterios de diagnostico / Caries detection technologies : the challenge of their use under different caries diagnostic criteria
The world development pattern of dental caries disease has increased the complexity of carious lesions diagnosis especially in occlusal surfaces by the visual-tactile exam, constituting one of the great challenges of the Public Health Dentistry. The aim of this study was to verify the reproducibility (intra and interexaminer Kappa [к] statistics) and t

6. Comparison between the digital radiographies through the conventional radiography of periodontal bone reabsorptions / Comparação entre as imagens radiográficas digital com a convencional das reabsorções ósseas periodontais
Comparing the periodontal bone defects, through data obtained with radiographies by the parallelism periapical te chnic, using the conventional and digital images. To obtain the images a x-ray device of the brand Dabi Atlante was used, where the radiographic exam was standardized to obtain a digital and conventional image with the best in detai l and the lea

7. Comparação entre diversas técnicas de imagem para diagnóstico do glaucoma / Comparison of different imaging techniques to diagnose glaucoma
O objetivo desse estudo foi comparar a habilidade da avaliação subjetiva do disco óptico e da camada de fibras nervosas (CFN) por oftalmologistas generalistas e por um glaucomatólogo com medidas objetivas pela tomografia de coerência óptica (Stratus OCT), oftalmoscopia confocal de varredura a laser (HRTIII), e a polarimetria de varredura a laser (GDxEC

8. "Análise comparativa das medidas de espessura da camada de fibras nervosas da retina de pacientes com atrofia em banda do nervo óptico e de indivíduos normais através da tomografia de coerência óptica e da polarimetria a laser" / A comparative analysis of the retinal nerve fiber layer thickness measurements in patients with band atrophy of the optic nerve and in normal controls using optical coherence tomography and scanning laser polarimetry
Most diseases that affect the optic pathways present clinically with loss of one or more visual functions.When optic pathway injuries involve the anterior visual pathways they may cause loss of the retinal nerve fiber layer (RNFL) and "band atrophy" (BA). The purpose of this study was therefore to compare the ability of the optical coherence tomography (OCT)

9. Avaliação de diferentes metodos empregados para o diagnostico da carie dentaria
O maior contato das populações com os compostos fluoretados é apontado, segundo vários pesquisadores, como o principal responsável pela queda da prevalência da cárie dentária, verificada mundialmente, durante as últimas décadas. As cavitações cariosas, quando ocorrem, estão surgindo num estágio bem mais avançado de desenvolvimento da doença,

10. Techniques for targeting screening in ulcerative colitis
Patients with longstanding chronic ulcerative colitis are “at risk” of developing colorectal cancer. Approximately 1 in 6 patients will die as a result of colorectal malignancy, which can often be difficult to detect using conventional “white light” colonoscopy. New endoscopic techniques and technologies including the use of dye sprays, “chromoendo

11. Endovascular surgery for peripheral arterial occlusive disease. A critical review.
Endovascular surgery is a new multidisciplinary field that applies the recently innovated techniques of angioscopy, intraluminal ultrasound, balloon angioplasty, laser, mechanical atherectomy, and stents. This field can be defined as a diagnostic and therapeutic discipline that uses catheter-based systems to treat vascular disease. As such, it integrates the

12. Monoclonal Antibody against Babesia equi: Characterization and Potential Application of Antigen for Serodiagnosis
Monoclonal antibody (MAb) BEG3 was produced against Babesia equi parasites to define a species-specific antigen for diagnostic use. The MAb reacted with single, paired, and Maltese cross forms of B. equi, and no reaction was observed with this MAb on acetone-fixed Babesia caballi, Babesia ovata, or Babesia microti parasites in the indirect immunofluorescent
