- A New 3D CT Method to Analyze Bronchial Stenosis after Lung Transplantation(2019) DIAS, Y. T. Nunes; CHATE, R. C.; NOGUEIRA FILHO, J. M.; CIRILLO, G. G.; PEGO-FERNANDES, P. M.; SAMANO, M. N.
bookPart Doença Pulmonar Obstrutiva Crônica Ocupacional(2014) ARBEX, Marcos Abdo; CHATE, Rodrigo Caruso- Computed tomography in hypersensitivity pneumonitis: main findings, differential diagnosis and pitfalls(2018) DIAS, Olivia Meira; BALDI, Bruno Guedes; PENNATI, Francesca; ALIVERTI, Andrea; CHATE, Rodrigo Caruso; SAWAMURA, Marcio Valente Yamada; CARVALHO, Carlos Roberto Ribeiro de; ALBUQUERQUE, Andre Luis Pereira deIntroduction: Hypersensitivity pneumonitis (HP) is a disease with variable clinical presentation in which inflammation in the lung parenchyma is caused by the inhalation of specific organic antigens or low molecular weight substances in genetically susceptible individuals. Alterations of the acute, subacute and chronic forms may eventually overlap, and the diagnosis based on temporality and presence of fibrosis (acute/inflammatory HP vs. chronic HP) seems to be more feasible and useful in clinical practice. Differential diagnosis of chronic HP with other interstitial fibrotic diseases is challenging due to the overlap of the clinical history, and the functional and imaging findings of these pathologies in the terminal stages.Areas covered: This article reviews the essential features of HP with emphasis on imaging features. Moreover, the main methodological limitations of high-resolution computed tomography (HRCT) interpretation are discussed, as well as new perspectives with volumetric quantitative CT analysis as a useful tool for retrieving detailed and accurate information from the lung parenchyma.Expert commentary: Mosaic attenuation is a prominent feature of this disease, but air trapping in chronic HP seems overestimated. Quantitative analysis has the potential to estimate the involvement of the pulmonary parenchyma more accurately and could correlate better with pulmonary function results.

- Texture-based classification of lung disease patterns in chronic hypersensitivity pneumonitis and comparison to clinical outcomes(2021) PENNATI, F.; ALIBONI, L.; ANTONIAZZA, A.; BERETTA, D.; DIAS, O.; BALDI, B. G.; SAWAMURA, M.; CHATE, R. C.; CARVALHO, C. R. R. De; ALBUQUERQUE, A.; ALIVERTI, A.Computer-aided detection algorithms applied to CT lung imaging have the potential to objectively quantify pulmonary pathology. We aim to develop an automatic classification method based on textural features able to classify healthy and pathological patterns on CT lung images and to quantify the extent of each disease pattern in a group of patients with chronic hypersensitivity pneumonitis (cHP), in comparison to pulmonary function tests (PFTs). 27 cHP patients were scanned via high resolution CT (HRCT) at full-inspiration. Regions of interest (ROIs) were extracted and labeled as normal (NOR), ground glass opacity (GGO), reticulation (RET), consolidation (C), honeycombing (HB) and air trapping (AT). For each ROI, statistical, morphological and fractal parameters were computed. For automatic classification, we compared two classification methods (Bayesian and Support Vector Machine) and three ROI sizes. The classifier was therefore applied to the overall CT images and the extent of each class was calculated and compared to PFTs. Better classification accuracy was found for the Bayesian classifier and the 16x16 ROI size: 92.1 +/- 2.7%. The extent of GGO, HB and NOR significantly correlated with forced vital capacity (FVC) and the extent of NOR with carbon monoxide diffusing capacity (DLCO).
- What happens to the pleural space affected by malignant effusion after bedside pleurodesis?(2018) ARAUJO, Pedro H. X. N. de; TERRA, Ricardo M.; SANTOS, Thiago da Silva; CHATE, Rodrigo C.; PAIVA, Antonio F. L. de; PEGO-FERNANDES, Paulo M.Background and objectivesEvaluate radiological characteristics of postpleurodesis pleural space of patients with recurrent malignant pleural effusion(RMPE). MethodsProspective cohort study including patients with RPME treated with bedside pleurodesis. We used CT scans to calculate pleural cavity volume immediately before pleurodesis(iCT) and 30 days after(CT30). Radiological evolution was calculated by the difference between pleural volumes on CT30 and iCT(volume). We categorized initial pleural volume as small(<500mL) or large space(500mL) and volume as positive(>254.49mL), unchanged(-268.77-254.49mL), or negative(<-268.77mL). Futhermore, we analyzed clinical effectiveness, pleural elastance, and adverse events. ResultsA total of 87 patients were analyzed. Pleural volume varied from 35-2750mL in iCT and from 0-2995mL in CT30(P=0.753). A total of 54 patients had initial small pleural space(62.06%) and 33 large(37.93%). Clinical failure occurred in 7.4% of small space group and in 24.6% of large(P=0.051, OR4.0(CI:1.098-14.570)). In small space group, 27.77% evolved with positive, 66.66% with unchanged and 5.55% with negative volume. In the large space group these numbers were respectively 21.21%, 27.27%, and 51.51%. ConclusionsThere is significant variability on pleural space volume. However, pleural volume remains unchanged in many cases. Besides that, more than half patients with initial large space coursed with relevant reduction. Finally, patients with initial small space presented a greater chance of clinical success.
- Safety and Systemic Consequences of Pleurodesis with Three Different Doses of Silver Nitrate in Patients with Malignant Pleural Effusion(2015) TERRA, Ricardo Mingarini; BELLATO, Renato Tavares; TEIXEIRA, Lisete Ribeiro; CHATE, Rodrigo Caruso; PEGO-FERNANDES, Paulo ManuelBackground: Silver nitrate (SN) is an alternative to talc pleurodesis in patients with malignant pleural effusion (MPE). Nevertheless, SN complications have not been thoroughly investigated so far. Objective: To evaluate frequent adverse events (AE) of SN treatment at three different doses for pleurodesis in patients with MPE. The secondary objective was to evaluate systemic inflammation, efficacy and quality of life in these patients. Methods: A double-blind, randomized, clinical trial was conducted in patients with recurrent MPE at a tertiary university hospital. The study patients underwent pleural catheter insertion and were randomly assigned to one of the three pleurodesis groups treated with 30 ml 0.3%, 30 ml 0.5% or 60 ml 0.3% SN. Patients were discharged 3 days after the procedure, and returned to follow-up visits on days 10 and 30. During follow-up, AE, inflammatory markers, quality of life and CT scans were systematically assessed and documented. Results: Sixty patients (11 males and 49 females, median age 62.13 years) were included. Overall, 199 AE were observed, including 23 serious AE. Grade 1/2 metabolic AE, such as increases in creatinine and liver enzymes, were the most frequent. Grade 3/4 hypoxia was observed in 13 patients. Four patients died, 3 due to disease progression and in 1 patient death was possibly related to pleurodesis. C-reactive protein levels increased in a dose-dependent manner and peaked 48 h after pleurodesis. No significant difference was observed among groups regarding quality of life or clinical/radiological recurrence. Conclusion: Hypoxia was the most significant AE following SN pleurodesis; mild metabolic events were very common. SN instillation causes substantial dose-dependent systemic inflammatory responses.
