BACKGROUND: Intensive follow-up after surgery for colorectal cancer is common practice but lacks a firm evidence base. OBJECTIVE: To assess whether or not augmenting symptomatic follow-up in primary care with two intensive methods of follow-up [monitoring of blood carcinoembryonic antigen (CEA) levels and scheduled imaging] is effective and cost-effective in detecting the recurrence of colorectal cancer treatable surgically with curative intent. DESIGN: Randomised controlled open-label trial...

BACKGROUND: In 2013, the US Preventive Services Task Force (USPSTF) began recommending lung cancer screening for high risk smokers aged 55-80 years using low-dose computed tomography (CT) scan. In light of these updated recommendations, there is a need to understand smokers' knowledge of and experiences with lung cancer screening in order to inform the design of patient education and tobacco cessation programs. The purpose of this study is to describe results of a qualitative study examining smokers' perceptions around lung cancer screening tests...

BACKGROUND: Transbronchial lung cryobiopsy (TBLC) can be indicated in diffuse parenchymal lung diseases (DPLDs) when a confident noninvasive diagnosis cannot be made. The 2 most relevant complications of TBLC are bleeding and pneumothorax (PTX). The accuracy of chest ultrasonography (US) for the detection of PTX is higher when compared to chest X-ray (CXR) with reference to computed tomography (CT) scan as a gold standard. OBJECTIVE: We evaluated the accuracy of chest US in detecting PTX after TBLC in patients with DPLDs...

Recurrent pneumonia is one of the most frequent reasons for referral to paediatric chest physicians. The diagnostic work-up is dependent on whether infection repeatedly occurs in the same lung lobe, or affects multiple lobes and/or different areas in different episodes. A 13-year-old girl was admitted with a second episode of right lower lobe pneumonia. The chest x-ray demonstrated an inhomogeneous opacity, without a clearly recognizable segmental distribution. A contrast-enhanced CT scan, was therefore performed that showed a polycyclic consolidation with blood supply from a systemic artery, originated from the thoracic aorta...

A 43-year old man presented with recurrent pneumonias, episodes of hemoptysis and an enlarging right lower lobe mass. A clear diagnosis was not previously established in spite of multiple radiological evaluations and biopsies. Meticulous review of his CT imaging showed that he had subcarinal calcification on his prior CT scans, which had decreased in size and now multiple new small areas of calcifications were seen in the right lower lobe lesion. An esophago-pulmonary fistula due to migration of mediastinal calcifications was suspected which was identified on careful review of the CT chest and confirmed by esophagogastroduodenoscopy...

A 28-year-old Filipino male was admitted due to high-grade fevers and dyspnea on a background of chronic cough and weight loss. Due to clinical and echocardiographic signs of cardiac tamponade, emergency pericardiocentesis was performed on his first hospital day. Five days after, chest radiographs showed new pockets of radiolucency within the cardiac shadow, indicative of pneumopericardium. On repeat echo, air microbubbles admixed with loculated effusion were visualized in the anterior pericardial space. Constrictive physiology was also supported by a thickened pericardium, septal bounce, exaggerated respiratory variation in AV valve inflow, and IVC plethora...

BACKGROUND: Electromagnetic navigational bronchoscopy (ENB) is guided-bronchoscopy to pulmonary nodules (PN) which relies on a pre-procedural chest CT to create a 3-dimensional (3-D) virtual airway map. The CT is traditionally done at a full inspiratory breath hold (INSP) but the procedure is performed while the patient tidal breaths, where lung volumes are closer to functional residual capacity. Movement of a PN from INSP to expiration (EXP) has been shown to average 17.6 mm. Therefore, the hypothesis of this study is that pre-procedural virtual maps built off a CT closer to physiological lung volumes during bronchoscopy may better represent the actual 3-D location of a PN...

OBJECTIVES: To investigate the diagnostic accuracy of CT coronary artery calcium scoring (CACS) with tin pre-filtration (Sn100kVp) using iterative beam-hardening correction (IBHC) calcium material reconstruction compared to the standard 120kVp acquisition. BACKGROUND: Third generation dual-source CT (DSCT) CACS with Sn100kVp acquisition allows significant dose reduction. However, the Sn100kVp spectrum is harder with lower contrast compared to 120kVp, resulting in lower calcium score values...

SETTING: Diabetes mellitus (DM) may increase risk of pulmonary tuberculosis (PTB) and influence its radiological manifestations. OBJECTIVE: To evaluate the impact of glycemic status on radiological findings of PTB in diabetic patients. METHODS: Between January 2010 and December 2015, chest radiographs (CXRs) in consecutive 214 DM patients with culture-proved PTB and 123 available thoracic computed tomography (CT) scans were enrolled. An equal number of non-DM patients with similar demographics was included as the control group...

Anaplastic large cell lymphoma (ALCL) is a CD30+ T-cell non-Hodgkin lymphoma with two main clinical presentations: primary cutaneous (pcALCL) and systemic (sALCL). While rare cases of myxoid sALCL have been reported, there are no previous cases of myxoid pcALCL reported. We present two unusual cases of pcALCL showing prominent collections of dermal mucin closely intermingling with the anaplastic lymphocytes. Patient 1 was a 30-year-old woman who presented with ulcerated nodules on her neck, abdomen, chest, and shoulders...

BACKGROUND: After appropriate initial therapy for patients with stage II-III melanoma, there is no consensus regarding surveillance. Thus, follow-up is highly variable among institutions and individual providers. The National Comprehensive Cancer Network recommends routine clinical examination and consideration of imaging for stage IIB-IIIC every 3-12 mo with no distinction between stages. Detection of recurrence is important as novel systemic therapies and surgical resection of recurrence may provide survival benefits...

REVIEW
Vasileios Kouranos, Joseph Jacob, Andrew Nicholson, Elizabetta Renzoni
The diagnosis of hypersensitivity pneumonitis (HP) relies on the clinical evaluation of a number of features, including a history of significant exposure to potentially causative antigens, physical examination, chest CT scan appearances, bronchoalveolar lavage lymphocytosis, and, in selected cases, histology. The presence of fibrosis is associated with higher morbidity and mortality. Differentiating fibrotic HP from the idiopathic interstitial pneumonias can be a challenge. Furthermore, even in the context of a clear diagnosis of fibrotic HP, the disease behaviour can parallel that of idiopathic pulmonary fibrosis in a subgroup, with inexorable progression despite treatment...

Anthony P Reeves, Yiting Xie, Shuang Liu
With the advent of fully automated image analysis and modern machine learning methods, there is a need for very large image datasets having documented segmentations for both computer algorithm training and evaluation. This paper presents a method and implementation for facilitating such datasets that addresses the critical issue of size scaling for algorithm validation and evaluation; current evaluation methods that are usually used in academic studies do not scale to large datasets. This method includes protocols for the documentation of many regions in very large image datasets; the documentation may be incrementally updated by new image data and by improved algorithm outcomes...

BACKGROUND Air embolism into the systemic arterial circulation secondary to pulmonary barotrauma has rarely been reported. Herein, we report the clinical course of an extremely rare presentation of cerebral air embolism likely due to ruptured pulmonary bullae during commercial air travel. CASE REPORT A 65-year-old man suddenly became unconscious during an airplane descent. Upon landing, he was immediately transferred to the nearest emergency department where he was intubated for airway protection. His head CT angiogram showed multiple air pockets in the right parietal lobe suspicious for multiple air emboli...

BACKGROUND: Congenital scoliosis is one of the 'difficult to treat' scenarios which a spine surgeon has to face. Multiple factors including the age of child at presentation, no definite pattern of deformity and associated anomalies hinder the execution of the ideal treatment plan. All patients of congenital scoliosis need to be investigated in detail. X rays and MRI of spine is usually ordered first. Screening investigations to rule out VACTERL (Visceral, Anorectal, Cardiac, Tracheo-esophageal fistula, Renal and Lung) abnormalities are required...

BACKGROUND: Respective proportions of final etiologies are disparate in cohorts of cardiac arrest patients, depending on examined population and diagnostic algorithms. In particular, prevalence and characteristics of sudden unexplained death syndrome (SUDS) are debated. We aimed at describing etiologies in a large cohort of aborted out-of-hospital cardiac arrest (OHCA) patients, in order to assess prevalence and outcome of SUDS. PATIENTS AND METHODS: We analyzed data from our prospective registry of successfully resuscitated OHCA patients admitted to a cardiac arrest centre between January 2002 and December 2014...

BACKGROUND: Trauma triage decisions can be influenced by both knowledge and experience. Consequently, there may be substantial variability in computed tomography (CT) scans desired by emergency medicine physicians, surgical chief residents, and attending trauma surgeons. We quantified this difference and studied the effects of each group's decisions on missed injuries, cost, and radiation exposure. METHODS: All blunt trauma activations at an urban level 1 trauma center were studied over a 6-mo period...
