Validation of a PNA-FISH method for the detection of Helicobacter pylori
Cerqueira, L.; Fernandes, RM.; Ferreira, RM.; Oleastro, M.; Carneiro, F.; Brandão, C.; Pimentel-Nunes, P.; Dinis-Ribeiro, M.; Figueiredo, C.Here, we evaluated a previously established peptide nucleic acid-fluorescence in situ hybridization (PNA-FISH) method as a new diagnostic test for Helicobacter pylori clarithromycin resistance detection in paraffin-embedded gastric biopsy specimens. Both a retrospective study and a prospective cohort study were conducted to evaluate the specificity and sensitivity of a PNA-FISH method to determine H. pylori cla...
Doença de Graves associada à artrite idiopática juvenil
Marques, VM; Dias de Carvalho, SC; Antunes, AM; Pinho-Marques, OA; Fernandes-Silva, MH; Costa-Vieira, MJThe authors report the case of a 10-year-old girl with Graves' disease (GD), treated with propylthiouracil, who developed uveitis and polyarticular arthritis, and whose mother also had GD and discoid lupus. The differential diagnosis of inflammatory arthritis that appears in a child with autoimmune thyroid disease managed with antithyroid drugs is discussed.

Helicobacter pylori colonization of the adenotonsillar tissue: fact or fiction?
Vilarinho, S; Guimarães, NM; Ferreira, RM; Gomes, B; Wen, XG; Vieira, MJ; Carneiro, F; Godinho, T; Figueiredo, COBJECTIVE: The transmission of the gastric pathogen Helicobacter pylori involves the oral route. Molecular techniques have allowed the detection of H. pylori DNA in samples of the oral cavity, although culture of H. pylori from these type of samples has been sporadic. Studies have tried to demonstrate the presence of H. pylori in adenotonsillar tissue, with contradictory results. Our aim was to clarify whether ...
