New lung tissue growth can occur in adults, defying previous belief

New Lung Tissue Growth Discovered: Is Some Lung Regeneration Possible? Lung regeneration has never been thought possible in adults. But Steven Mentzer et al from Brigham and Women’s at Harvard reported a case of a 33 year old woman who had an apparent 64% increase in the number of functioning alveoli in her left lung, during [… read more]

"Practice ischemia" on an arm reduces contrast nephropathy after procedures (RCT)

Contrast-induced nephropathy (kidney damage) is a serious problem that can occur after many medical tests and procedures, but coronary angiography (cardiac catheterization) is the main culprit. People with pre-existing renal disease are most susceptible to contrast-induced nephropathy (CIN) — about 1 in 8 of them develop a “bump” in creatinine of >0.5 mg/dL after cardiac [… read more]

Advanced bronchoscopy yields are 70% in meta-analysis (Review)

(image: Wikipedia) As one after another specialty society endorses routine lung cancer screening with chest CT scans, we all know a Nodule Storm is coming to a pulmonology clinic near you. Thankfully, smart people are asking how we can systematically and successfully handle this soon-to-be-common outpatient clinical problem. Most of these many thousands of nodules [… read more]

Sharpen your eye with these free online radiology tutorials

Pulmonologists become fairly good semi-professional chest radiologists simply by showing up, paying attention and working hard during their training, and making an effort to keep learning throughout their careers. We have the advantage over radiologists of actually being able to “clinically correlate” the findings with what’s really going on, and to integrate that into our understanding [… read more]

How to make $25,000 on each EBUS (Chest)

(image: flickrCC) Endobronchial ultrasound with transbronchial needle aspiration (EBUS-TBNA), when performed by skilled physicians, reduces the need for mediastinoscopy and unnecessary thoracotomies with their associated morbidity, and is poised to permanently alter the landscape of lung cancer diagnosis and staging. Prior to 2008, Medicare seemed to recognize the potential value of EBUS by paying hospitals [… read more]

The 5-year results of the Danish Lung Cancer Screening Trial (DLCST) were reported in the April 2012 Thorax, and they show no mortality benefit from annual screening for lung cancer with chest CT. Rather, it appeared that more harmless early stage cancers were identified through screening — “overdiagnosis” of cancers that would never have advanced [… read more]

Mazen Albeldawi and Rohit Makkar of the Cleveland Clinic bring us a free image in the New England Journal of what the bronchial tree looks like when a barium swallow test goes horribly awry. This patient had a very poor outcome, particularly unfortunate since this was an elective test. The New England Journal also ran a previous [… read more]

When someone with a pneumothorax lies supine — as in the 23-year old man described in this New England Journal mini-case from Saweera Sabbar and Eric James Nilles of Rashid Trauma Center in Dubai, UAE — air rises laterally and caudally, and creates displacement downward and medially of the hemidiaphragm, displaying as the “deep sulcus [… read more]

Jean-Pierre Tourtier and Sophie Cottez of the Military Hospital Val-de-Grâce, Paris share the case of a 61-year-old man who underwent vertebroplasty after a therapeutic laminectomy for resection of a vertebral hemangioma. Cement made it into his paravertebral vascular system, and thence to his systemic circulation and pulmonary arteries, where it made for some interesting radiographic pictures. [… read more]

Hayder Saeed and Suleiman Massarweh of the University of Kentucky share with us the story and images of a woman presenting with weight loss and cough, and discovered to have hypertrophic pulmonary osteoarthropathy, velvety palmar skin, clubbing … and an 11 cm adenocarcinoma in the right lung. Saeed H, Massarweh S. Hypertrophic Pulmonary Osteoarthropathy and [… read more]

Richard Light and friends established that parapneumonic effusions (PPE) associated with community-acquired pneumonia very rarely progress if the effusion is freely layering and less than 1 cm in height on a lateral decubitus chest film. But who orders those anymore? Chest CT use has risen 20-fold since Light’s seminal 1980 paper. Often the CT has [… read more]

A 40-year old asthmatic woman coughed the corner of her right lower lobe right through her chest wall, needing a thoracotomy to repair it. She seemed to have recovered well at 3-month follow-up. Matthew O’Shea and Morgan Cleasby of Good Hope Hospital in Birmingham (United Kingdom) share their fascinating pictures in a New England Journal show-and-tell. [… read more]

The National Lung Screening Trial demonstrated annual screening with chest CT saves one life per 320 screened compared to yearly screening with chest radiography. However, there was no “usual care” group (no screening at all) to compare against. Oken et al report additional results from the PLCO Trial (Prostate, Lung, Colorectal, and Ovarian Cancer Screening [… read more]

Ultrasound is the future. It’s even better than that: it’s the present. So say proponents Seth Koenig, Mangala Narasimhan and pioneer & innovator Paul Mayo in this month’s CHEST review. They endorse a “paradigm shift” meaning, in effect, you get professionally trained on this highly versatile, effective, and immediate-results-providing modality and integrate it into your routine [… read more]

Results of the National Lung Screening Trial (NLST) are in! Enrollment was 8/2002 to 4/2004. Follow-up was through end of 2009. Patients were age 55-74, with >30 pack-year smoking history, still smoking or quit <15 years. Intervention / Control: Low-dose chest CT vs. chest plain films thrice-yearly. By screening these 53,454 high-risk people, 62 deaths [… read more]
