Nocardiosis is a rare cause of opportunistic infection post hematopoietic stem cell transplant (HSCT) occurring in about 0.3% of patients. The risk factors include delayed immune reconstitution, prolonged neutropenia, and graft-versus-host disease. The most common site of infection is the lung, followed by the brain and the skin. Concomitant pulmonary and central nervous system (CNS) nocardiosis is an extremely rare entity as presented in our case. We present the case of a 72-year-old male at 137 days post transplant presenting with complaints of headache and slurred speech...

PURPOSE: Radiopharmaceuticals containing the motive tripeptide arginyl-glycyl-asparatic acid (RGD) are known to target ανβ3 integrins during tumor angiogenesis. A more generic kit radiolabeling procedure accommodating Ga-68 from different generators was developed for NOTA-RGD and evaluated for its versatile use and safety in subsequent in vivo applications. The [(68)Ga]NOTA-RGD kit was further verified for its expected biodistribution and pharmacokinetics in nonhuman primates and its clinical sensitivity to detect solitary pulmonary nodules (SPN) in cancer patients...

Small cell lung cancer (SCLC) often presents with either regional or systemic metastases, but approximately 4% of patients present with a solitary pulmonary nodule. Surgical resection can be an option for these patients and is endorsed by the National Comprehensive Cancer Network (NCCN) guidelines. There are no prospective randomized clinical trials evaluating the role of adjuvant systemic therapy in these resected SCLC patients. A recent National Cancer Database analysis found that the receipt of adjuvant chemotherapy alone [hazard ratio (HR), 0...

Indeterminate pulmonary nodules are commonly encountered and often result in costly and invasive procedures that eventually turn out to be unnecessary. Current prediction models can help to estimate the pretest probability of cancer and assist in determining a strategy of observation with serial imaging for a low pretest probability of cancer, and a more aggressive approach for those patients with a high pretest probability. However, the majority of patients will have an intermediate pretest probability which becomes complex...

BACKGROUND: In some patients, non-tuberculous mycobacteria (NTM) infections manifest in solitary nodules (solitary nodular [SN] type) generally caused by Mycobacterium avium complex (MAC). In patients treated using surgical resection, the American Thoracic Society guidelines state that postoperative chemotherapy is not necessary in the absence of lesions, although there have been a few reports of such cases. METHODS: Twenty-eight patients diagnosed with NTM who underwent solitary pulmonary nodule resection at Toneyama Hospital, Osaka, Japan, between January 2000 and October 2012 were enrolled...

Many studies have shown a statistically significant increase of life-time risk of radiation-induced cancer from CT examinations. In this context, in Canada, the Quebec's provincial clinical center of expertise in radiation safety (CECR) has led a province-wide tour of 180 CT installations in order to: (i) evaluate the technical and functional performance of CT scanners, (ii) evaluate and improve radiation safety practices and (iii) initiate, with local teams, a CT dose optimization process. The CT tour consisted of a two day visit of CT installations by a CECR multidisciplinary team of medical physicists, engineers and medical imaging technologists (MITs) carried out in close collaboration with local teams composed of MITs, radiologists, physicists, engineers and managers...

Bundled or episode payments are among the most heavily emphasized approaches to aligning incentives and promoting care coordination, efficiency, and accountability in health care redesign. Bundled or episode payments price a market basket of services for an entire episode of care with both a clearly defined trigger and termination. Because the radiologist is "ancillary" in many bundles, the specialty is often unaware of the phenomenon. This is likely to change rapidly. Radiology is pivotal in high-prevalence, high-impact care areas such as low back pain and stroke that are focuses of widely used system performance metrics...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become the treatment of choice in patients with severe aortic valve stenosis who are not eligible for operative replacement and an alternative for those with high surgical risk. Due to high age and smoking history in a high proportion of TAVI patients, suspicious findings are frequently observed in pre-procedural chest computer tomography (CCT). METHODS: CCT scans of 484 consecutive patients undergoing TAVI were evaluated for incidentally discovered solitary pulmonary nodules (SPN)...

BACKGROUND: American College of Chest Physicians (ACCP) provides guidelines to manage pulmonary nodules. Pulmonary nodules however can be malignant or benign. Similar incidence of tuberculosis (TB) and lung cancer in Asian countries raises concern over the relevance of suggested guidelines in Asian population. There is little data on the pattern of clinical practice in the management of pulmonary nodules in Asian country (Singapore). Our study describes the current pattern of clinical practice in this area highlighting the variation in practice and discussing the potential reasons...

RATIONALE: Many patients are diagnosed with small pulmonary nodules for which professional societies recommend subsequent imaging surveillance. Adherence to these guidelines involves many steps from both clinicians and patients but has not been well studied. OBJECTIVES: In a health care setting with a nodule tracking system, we evaluated the association of communication processes and distress with patient and clinician adherence to recommended follow up and Fleischner Society guidelines, respectively...

The British Thoracic Society guideline on the investigation and management of pulmonary nodules is based on a comprehensive and systematic review of the literature on pulmonary nodules. Recent evidence has suggested that significant changes to existing guidelines are necessary. The use of 2 malignancy prediction calculators to better characterize the risk of malignancy was firmly supported by evidence, as were the recommendations for a higher nodule size threshold for follow‑up (≥5 mm or ≥80 mm3) and a reduction of the follow‑up period to 1 year for solid pulmonary nodules...

BACKGROUND: American College of Chest Physicians (CHEST) clinical practice guidelines on the evaluation of pulmonary nodules may have low adoption among clinicians in Asian countries. Unique patient characteristics of Asian patients affect the diagnostic evaluation of pulmonary nodules. The objective of these clinical practice guidelines was to adapt those of CHEST to provide consensus-based recommendations relevant to practitioners in Asia. METHODS: A modified ADAPTE process was used by a multidisciplinary group of pulmonologists and thoracic surgeons in Asia...

Lung cancer screening has come a long way since the early studies with chest X-ray. Advancing technology and progress in the processing of images have enabled low dose CT to be tried and tested, and evidence suggests its use can result in a significant mortality benefit. There are several issues that need refining in order to successfully implement screening in the UK and elsewhere. Some countries have started patchy implementation of screening and there is increased recognition that the appropriate management of pulmonary nodules is crucial to optimise benefits of early detection, while reducing harm caused by inappropriate medical intervention...

BACKGROUND: Lung cancer is the most common cause of cancer deaths in the United States. Overall survival is less than 20%, with the majority of patients presenting with advanced disease. The National Lung Screening Trial, performed mainly in academic medical centers, showed that cancer mortality can be reduced with computed tomography (CT) screening compared with chest radiography in high-risk patients. To determine whether this survival advantage can be duplicated in a community-based multidisciplinary thoracic oncology program, we initiated a CT scan screening program for lung cancer within an established health care system...
