BACKGROUND: Concerted management of the traumatic hemothorax is ill-defined. Surgical management of specific hemothoraces may be beneficial. A comprehensive strategy to delineate appropriate patients for additional procedures does not exist. We developed an evidence-based algorithm for hemothorax management. We hypothesize the use of this algorithm will decrease additional interventions. METHODS: A pre/post study was performed on all patients admitted to our trauma service with traumatic hemothorax from August 2010 to September 2013...

Tuberculosis is a public health problem worldwide, including in the United States-particularly among immunocompromised patients and other high-risk groups. Tuberculosis manifests in active and latent forms. Active disease can occur as primary tuberculosis, developing shortly after infection, or postprimary tuberculosis, developing after a long period of latent infection. Primary tuberculosis occurs most commonly in children and immunocompromised patients, who present with lymphadenopathy, pulmonary consolidation, and pleural effusion...

REVIEW
Ruza Stevic, Branislava Milenkovic
Tumors of trachea and bronchi are uncommon and can occur in the form of benign or low- and high-grade malignant tumors. Although tracheobronchial tumors (TBTs) represent only 0.6% of all pulmonary tumors, they are clinically significant. Delays in diagnosis of these tumors commonly occur because the signs and symptoms caused by these tumors are nonspecific and chest radiographs are often considered unremarkable. Therefore, novel radiological techniques and better access to flexible bronchoscopy enable detection of larger number of TBT...

We report the case of a patient with a history of chronic bronchiectasis that presented with new onset fatigue, shortness of breath, peripheral blood eosinophilia and infiltrates on chest radiograph. Eight days previously, she was prescribed inhaled colistimethate sodium 75 mg bid to prevent exacerbations of her respiratory condition. To our knowledge, our case is the first to show the clinical and radiologic features of inhaled-colistimethate-induced pulmonary eosinophilia. It also shows the rapid resolution of its features following treatment with oral corticosteroids...

Totally implanted port devices are important for the administration of fluid and chemotherapeutic agents. However, their use may be associated with serious complications, such as catheter fracture and embolism. Most data on port catheter embolization consist of isolated case reports. We report a 6-year-old boy with relapse of an acute lymphoblastic leukemia. He presented with dysfunction of his totally implanted port device. Radiologic examination revealed a catheter fracture. Echocardiography showed the catheter embolized into the right ventricle...

CLINICAL/METHODICAL ISSUE: Pulmonary infections are a common complication in immunosuppressed patients with a frequently fatal prognosis despite modern prophylactic therapy. An early and correct diagnosis is important for initiation of the appropriate therapy. STANDARD RADIOLOGICAL METHODS: Chest radiography is the preferred initial imaging examination but is not accurate enough for the detection of pulmonary infections in immunosuppressed patients. METHODICAL INNOVATIONS: Pneumonia is caused by a broad spectrum of pathogens in immunocompromised patients...

DEFINITION: Intrapulmonary nodules generally represent an incidental finding in the roentgenogram or computed tomography (CT) scan of the chest. They are defined as single, well-circumscribed, radiographic opaque lesions that measures up to 3 cm in diameter and are surrounded completely by aerated lung. The probability of malignancy directly correlates with increasing diameter. Lesions that have a diameter of 1 cm or larger require direct evaluation. THERAPY: Surgery is the first option for patients with a malignant lesion, given an acceptable perioperative risk; for high-risk patients either radiofrequency ablation (RFA) or stereotactic body radiation therapy (SBRT) should be offered...

S Poetter-Lang, C J Herold
CLINICAL ISSUE: The diagnosis of community-acquired pneumonia (CAP) is often not possible based only on the clinical symptoms and biochemical parameters. STANDARD RADIOLOGICAL METHODS: For every patient with the suspicion of CAP, a chest radiograph in two planes should be carried out. Additionally, a risk stratification for the decision between outpatient therapy or hospitalization is recommended. METHODICAL INNOVATIONS: Based on the evaluation of the different radiological patterns as well as their extent and distribution, a rough allocation to so-called pathogen groups as well as a differentiation between viral and bacterial infections are possible; however, because different pathogens cause different patterns an accurate correlation is not feasible by relying purely on imaging...

INTRODUCTION: Stem cell transplantation is today's procedure of choice for management of various hematopoietic malignant and severe immunogenic disorders. High Resolution Computed Tomography (HRCT) is a common technique for the diagnosis of pulmonary complications in stem cell transplant recipients. There are a large number of complications which can complicate the post-transplant period. AIM: To study the role of HRCT chest in stem cell transplant patients developing pulmonary complications, detect any evidence of infection, detect clinical signs of lung infections, Graft versus Host Disease (GvHD) or other regimen related toxicities outlined earlier, detect any evidence of GvHD and correlate these clinical signs with radiological changes in the lungs...
