Certification system for multidisciplinary thoracic tumour boards.

In Spain, lung cancer (LC) is the fourth most common cancer. Managing LC involves different professionals, and cooperative and coordinated work is crucial. Therefore, important decisions are better made by Multidisciplinary Thoracic Tumour Boards (MTTBs).

Nintedanib in chronic fibrosing interstitial lung diseases. A case series.

Progressive pulmonary fibrosis (PPF) can be fatal in non-idiopathic interstitial lung diseases. We report a descriptive series of 13 patients with PPF who received treatment with nintedanib, a multitargeted tyrosine kinase inhibitor with antifibrotic effect. Although the reduced number of patients and the observational nature of a case series prevent us from providing strong evidence, our results suggest that nintedanib could be effective in PPF of various etiologies.

Radiological usual interstitial pneumonia pattern is associated with two-year mortality in patients with idiopathic pulmonary fibrosis.

Introduction: The new diagnostic guidelines for idiopathic pulmonary fibrosis (IPF) did not rule out the possibility of combining the radiological patterns of usual interstitial pneumonia (UIP) and probable UIP, given the similar management and diagnostic capacity. However, the prognostic implications of these patterns have not been fully elucidated, with different studies showing heterogeneous results. We applied the new criteria to a retrospective series of patients with IPF, assessing survival based on radiological patterns, findings, and their extension.

Strategies for calculating contrast media dose for chest CT.

Background: Total body weight (TBW) is a frequently used contrast media (CM) strategy for dose calculation in enhanced CT, yet it is suboptimal as it lacks consideration of patient characteristics, such as body fat percentage (BFP) and muscle mass. Alternative CM dosage strategies are suggested by the literature. Our objectives were to analyze the CM dose impact when adjusting to body composition using methods of obtaining lean body mass (LBM) and body surface area (BSA) along with its correlation with demographic factors in contrast enhanced chest CT examinations.

Sclerosing pneumocytoma with carcinoid tumorlets and neuroendocrine cell hyperplasia.

Sclerosing pneumocytoma is an uncommon pulmonary tumor which generally behaves benignly and occurs predominately in women. Rarely, it is associated with neuroendocrine proliferations such as hyperplasia, tumorlets and carcinoid tumors, which may be observed in relation to the tumor or in the distant lung parenchyma; the mechanism underlying this neuroendocrine differentiation is not clear. We present a case of a 33 year-old male with sclerosing pnemocytoma with coexistent neuroendocrine hyperplasia and combined carcinoid tumorlets.

Pathological Findings Associated With SARS-CoV-2 on Postmortem Core Biopsies: Correlation With Clinical Presentation and Disease Course.

Background: Autopsies can shed light on the pathogenesis of new and emerging diseases.

Aim: To describe needle core necropsy findings of the lung, heart, and liver in decedents with COVID-19.

Material: Cross-sectional study of needle core necropsies in patients who died with virologically confirmed COVID-19.

Mosaic attenuation in non-fibrotic areas as a predictor of non-usual interstitial pneumonia pathologic diagnosis.

The new radiological diagnostic criteria for diagnosing idiopathic pulmonary fibrosis (IPF) seek to optimize the indications for surgical lung biopsy (SLB). We applied the new criteria to a retrospective series of patients with interstitial lung disease (ILD) who underwent SLB in order to analyse the correlation between the radiological findings suggestive of another diagnosis (especially mosaic attenuation and its location with respect to fibrotic areas) and the usual interstitial pneumonia (UIP) pathologic diagnosis. Two thoracic radiologists reviewed the HRCT images of 83 patients with ILD and SLB, describing the radiological findings and patterns based on the new criteria.

The role of unenhanced phase of the liver in the scanning protocol of metastatic breast cancer: implications for sensitivity, response evaluation and size measurement.

Background: To analyse if performing unenhanced CT of the liver aids in the evaluation of metastatic lesions, response assessment or alter the size of the lesions, compared with portal phase alone, in patients with hepatic metastases from breast carcinoma.

Patients And Methods: One-hundred and fifty-three CT scans of 36 women were included. Scans consisted of unenhanced, arterial and portal delayed phases of the liver.

Post-acute COVID-19 syndrome. Incidence and risk factors: A Mediterranean cohort study.

Objectives: This study aims to analyze the incidence of Post-acute COVID-19 syndrome (PCS) and its components, and to evaluate the acute infection phase associated risk factors.

Methods: A prospective cohort study of adult patients who had recovered from COVID-19 (27th February to 29th April 2020) confirmed by PCR or subsequent seroconversion, with a systematic assessment 10-14 weeks after disease onset. PCS was defined as the persistence of at least one clinically relevant symptom, or abnormalities in spirometry or chest radiology.

Best Protocol for Combined Contrast-Enhanced Thoracic and Abdominal CT for Lung Cancer: A Single-Institution Randomized Crossover Clinical Trial.

Objective: The purpose of this study was to evaluate the superiority of either of two protocols for combined contrast-enhanced thoracic and abdominal CT of patients with lung cancer by comparing contrast enhancement, contrast-related artifacts, image quality, and radiation dose.

Subjects And Methods: In this randomized controlled crossover clinical trial, 77 patients who underwent 203 CT examinations were enrolled. All patients underwent at least two examinations performed with both protocols.

Transsphenoidal Approach in Endoscopic Endonasal Surgery for Skull Base Lesions: What Radiologists and Surgeons Need to Know.

In the last 2 decades, endoscopic endonasal transsphenoidal surgery has become the most popular choice of neurosurgeons and otolaryngologists to treat lesions of the skull base, with minimal invasiveness, lower incidence of complications, and lower morbidity and mortality rates compared with traditional approaches. The transsphenoidal route is the surgical approach of choice for most sellar tumors because of the relationship of the sphenoid bone to the nasal cavity below and the pituitary gland above. More recently, extended approaches have expanded the indications for transsphenoidal surgery by using different corridors leading to specific target areas, from the crista galli to the spinomedullary junction.

Has "respiratory coaching" before deep inspiration an impact on the incidence of transient contrast interruption during pulmonary CT angiography?

Purpose: To evaluate if respiratory coaching performed prior to CT pulmonary angiography (CTPA) image acquisition has an impact on the occurrence of transient interruption of contrast (TIC) phenomenon.

Materials And Methods: Two hundred and thirty-one consecutive patients with suspected pulmonary embolism (PE) were referred for CTPA. They were randomised into two groups, with or without respiratory coaching (groups A and B, respectively).

[Radiological anatomy of the ethmoidal arteries: CT cadaver study].

Introduction And Objectives: Our aim was to study the radiological anatomy of the ethmoidal arteries.

Methods: A descriptive study was performed including CT images of 20 cadaver heads. The specimens were perfused with a radiopaque material and various anatomical parameters were analysed.
