1. Hairy Tongue: Differential Diagnosis by Use of Widefield Optical Fluorescence
Resumo A língua pilosa é uma patologia benigna, caracterizada clinicamente por placas hiperqueratinizadas na face dorsal da língua, semelhante a pelos, cuja coloração varia de despigmentada, esbranquiçada, amarelada, verde, acastanhada a preta. O diagnóstico é clínico, e em casos de placas esbranquiçadas, pode ser difícil diferenciar entre leucopl

2. Feasibility of Robot - assisted Segmental Ureterectomy and Ureteroureterostomy in Patient with High Medical Comorbidity
ABSTRACT Introduction and objectives Nephroureterectomy remains the gold standard treatment option for upper tract tumors. However, segmental ureterectomy may be another option in patients with single kidney, borderline renal function or high medical comorbidities. The aim of this video is to assess the feasibility of robotic surgery as a minimally invasiv

3. Helicobacter pylori as a potential target for the treatment of central serous chorioretinopathy
OBJECTIVES: The objective of this study was to evaluate the relationship between the treatment of Helicobacter pylori gastric infection and changes in best-corrected visual acuity and macular detachment in patients with chronic central serous chorioretinopathy. METHODS: Seventeen patients diagnosed with central serous chorioretinopathy were examined for gast

4. Pathological and ultrastructural analysis of surgical lung biopsies in patients with swine-origin influenza type A/H1N1 and acute respiratory failure
BACKGROUND: Cases of H1N1 and other pulmonary infections evolve to acute respiratory failure and death when co-infections or lung injury predominate over the immune response, thus requiring early diagnosis to improve treatment. OBJECTIVE: To perform a detailed histopathological analysis of the open lung biopsy specimens from five patients with ARDS with conf

5. Cromoscopia óptica com tecnologia de banda estreita versus cromoscopia com solução de Lugol no diagnóstico do carcinoma superficial de esôfago em pacientes com câncer de cabeça e pescoço / Narrow band imaging versus chromoendoscopy with Lugols solution for esophageal squamous cell carcinoma detection
Background and study aims: The aim of this study was to compare narrow band imaging (NBI) without magnification and chromoendoscopy with Lugols solution for detecting superficial esophageal squamous cell carcinoma in patients with head and neck cancer. Patients and methods: This is a prospective observational study of 129 patients with primary head and neck

7. Expression and localization of myogenic regulatory factors (MyoD and Myogenin) in somatic rat muscle after reinervation with vein graft tubulization / Expressão e localização de fatores regulatórios miogênicos (MyoD e Miogenina) em músculos somíticos de ratos reinervados pela técnica de tubulização
Peripheral nerve injuries can result in the loss of propioception, morphological and functional alterations of muscle fibers which causes a negative impact on the quality of life. These injuries elicit an alteration on the expression of muscle specific genes, like MyoD and Myogenin, involved in the satellite cell activation and muscle mass regulation. The ve

8. Concurrent MRI and diffuse optical tomography of breast after indocyanine green enhancement
We present quantitative optical images of human breast in vivo. The images were obtained by using near-infrared diffuse optical tomography (DOT) after the administration of indocyanine green (ICG) for contrast enhancement. The optical examination was performed concurrently with a magnetic resonance imaging (MRI) exam on patients scheduled for excisional

9. Tissue diagnosis of intestinal microsporidiosis using a fluorescent stain with Uvitex 2B.
AIMS--To detect intestinal microsporidiosis in paraffin wax embedded biopsy specimens using a fluorescence technique incorporating optical brighteners. METHODS--Eight HIV infected patients with confirmed intestinal microsporidiosis (six with Enterocytozoon bieneusi, one with Encephalitozoon intestinalis and one with Encephalitozoon cuniculi infection) and 10

10. Rapid colorimetric hybridization assay for detecting amplified Helicobacter pylori DNA in gastric biopsy specimens.
A very simple, practical, sensitive, and specific colorimetric hybridization assay for detecting amplified Helicobacter pylori DNA is described. This assay, which combines a sensitive sandwich DNA hybridization reaction and a colorimetric protocol similar to those used in conventional enzyme immunoassays, was shown to be suitable for detecting H. pylori-infe

11. Light and electron microscopic demonstration of extracellular immunoglobulin deposition in renal tissue.
Extracellular immunoglobulin (IgG) deposits were shown by both light and electron microscopy in renal biopsy material using immunogold labelling. After fixation of tissue in 4% paraformaldehyde and embedding in Lowicryl K4M, semithin sections were cut and stained using the immunogold silver stain. The sections were then viewed and areas of interest were note

12. Simple colorimetric microtiter plate hybridization assay for detection of amplified Mycobacterium leprae DNA.
The detection of amplified products resulting from polymerase chain reactions (PCRs) remains a complicated process. To simplify the detection procedures, we developed a colorimetric microtiter plate hybridization assay for the specific detection of 5'-biotinylated PCR fragments of Mycobacterium leprae DNA. For this assay, an M. leprae DNA capture probe was m
