RESUMO
OBJECTIVE: The comparison between different techniques to quantify the 3-dimensional size of inflammatory bone erosions in rheumatoid arthritis(RA) patients. METHODS: Anti-cyclic citrullinated peptide antibody(ACPA) positive RA patients received high-resolution peripheral quantitative computed tomography (HR-pQCT) scans of the metacarpophalangeal joints (MCP). Erosions were measured by three different segmentation techniques: (1) manual method with calculation by half-ellipsoid formula, (2) semi-automated modified Evaluation Script for Erosions (mESE), and (3) semi-automated Medical Image Analysis Framework (MIAF) software. Bland & Altman plots were used to describe agreement between methods. Furthermore, shape of erosions was classified as regular or irregular and then compared to the sphericity obtained by MIAF. RESULTS: A total of 76 erosions from 65 RA patients (46 females/19 males), median age 57 years, median disease duration 6.1 years and median disease activity score 28 of 2.8 units were analyzed. While mESE and MIAF showed good agreement in the measurement of erosion size, the manual method with calculation by half-ellipsoid formula underestimated erosions size, particularly with larger erosions. Accurate segmentation is particularly important in larger erosions, which are irregularly shaped. In all three segmentation techniques irregular erosions were larger in size than regular erosions (MIAF: 19.7 vs. 3.4mm3; mESE: 15.5 vs. 2.3mm3; manual = 7.2 vs. 1.52mm3; all p < 0.001). In accordance, sphericity of erosions measured by MIAF significantly decreased with their size (p < 0.001). CONCLUSION: MIAF and mESE allow segmentation of inflammatory bone erosions in RA patients with excellent inter reader reliability. They allow calculating erosion volume independent of erosion shape and therefore provide an attractive tool to quantify structural damage in individual joints of RA patients.

BACKGROUND: Takayasu arteritis (TA) is a rare chronic granulomatous inflammatory disease of the aorta and/or its major branches and more frequently affects female patients before menopause. Since persistent inflammation may lead to arterial ischemia, hypertension is an important complication of TA. OBJECTIVES: To evaluate gestational results and complications in patients with TA. METHODS: We conducted a retrospective analysis of the medical records of patients with TA admitted to the high risk pregnancy clinic for women with systemic autoimmune diseases at Hospital Universitário Pedro Ernesto. RESULTS: From 1998 to 2011 we followed 11 pregnancies in 9 patients with TA; the patients' age ranged from 17 to 42 years and disease duration from 2 to 28 years. In 7 of the 11 pregnancies, uncontrolled blood pressure occurred before labor and preeclampsia was diagnosed in one. Two deliveries were preterm, one newborn was treated for sepsis, and four (36%) had intrauterine growth restriction (IUGR). CONCLUSIONS: Close monitoring improves the perinatal outcomes in patients with TA who are more prone to develop hypertension, preeclampsia and IUGR. Disease activity was not observed in our group of patients during pregnancy. Coordinated care between the obstetric, rheumatologic and cardiologic teams is the ideal setting to follow pregnant women with TA.

Os autores relatam o caso de um homem de 49 anos, com quadro de síndrome consumptiva e múltiplas cavitações pulmonares há cinco anos. Foi tratado para tuberculose, em duas ocasiões, sem melhora da sintomatologia. O paciente foi internado com quadro de dispnéia em repouso e febre, sendo sua cultura de escarro positiva para Sporothrix schenckii. O objetivo deste trabalho é apresentar uma forma rara de esporotricose e ressaltar a importância de seu reconhecimento.
A 49 year-old white man was admitted with dyspnea, cough and fever, with a history of consumptive syndrome and pulmonary cavitary disease for the past five years. He was treated twice for pulmonary tuberculosis previously, but without responses. His sputum culture was positive for Sporothrix schenckii. The ocurrence of sporotrichosis as a disease of the lung without cutaneos involvement is rare. So the subject of this report is to describe a case of pulmonary sporotrichosis and show the importance of its recognition.
