  • The Institutional Review Board approved this retrospective study, with a waiver of informed consent from the patients. TB outbreaks occurred in 15 senior high schools and chest radiographs from 58 students with identical strains of TB were analyzed by restriction fragment length polymorphism analysis by two independent observers. Lesions of nodule(s), consolidation, or cavitation in the upper lung zones were classified as typical TB.

  • Our aim was to evaluate the effect of human immunodeficiency virus (HIV) disease stage on chest radiographic (CXR) findings among patients with HIV-related pulmonary tuberculosis (TB). Data are from a prospective multicenter treatment trial for HIV-related TB. Baseline CXR findings and CD4/ lymphocyte counts were compared among patients with HIV-related TB. Data from published studies describing CXR findings in HIV-infected patients were reviewed and a pooleddata analysis was conducted. Of 135 patients with culture-confirmed HIV-related TB, 128 had both CXR and CD4/ lymphocyte data.

  • This book arose because of the huge amounts of clinical material that pass through the Singapore General Hospital, the largest tertiary care hospital in Singapore. A significant proportion of our patients come to us for a second opinion from the neighboring countries. Often they come to consult us for an abnormality on a chest radiograph. Pulmonary Medicine is largely based on the strong foundation of the plain chest radiograph. Indeed, chest radiography is the single most common investigation carried out in hospital practice.

  • This manual on radiographic technique and projections, is a successor to the Manual of Radiographic Technique that was published in 1986 with Drs T Holm, P Palmer and E Lehtinen as authors, and was meant as a manual for the WHO Basic Radiological System—WHO-BRS. The present manual can be used with any equipment, but is especially designed for the use with X-ray machines that comply with the specifications for the World Health Organization Imaging System for Radiology, WHIS-RAD.

  • Pulmonary tuberculosis produces a broad spectrum of radiographic abnormalities. During the primary phase of the disease these include pulmonary consolidation (50%), which often involves the middle or lower lobes or the anterior segment of an upper lobe; cavitation (29%) or pneumatocele formation(12%); segmental orlobar atelectasis(18%); pleural effusion (24%); hilar and mediastinal lymphadenopathy (35%); disseminated miliary disease (6%); and a normal chest radiograph (15%).

  • This book was written with the intention to pursue Dr. Stephen Goldberg's vision to make learning ridiculously simple. It is designed to rapidly teach the clinically vital components of radiology. The reader will acquire a solid approach to radiographic examinations commonly interpreted without radiologist assistance, and will become comfortable at recognizing common and dangerous conditions. Although this book is intended for medical students and interns, it is also useful for nurses, nurse practitioners and X-ray technicians....

  • Management of Occult and Stage 0 Carcinomas In the uncommon situation where malignant cells are identified in a sputum or bronchial washing specimen but the chest radiograph appears normal (TX tumor stage), the lesion must be localized. More than 90% can be localized by meticulous examination of the bronchial tree with a fiberoptic bronchoscope under general anesthesia and collection of a series of differential brushings and biopsies. Often, carcinoma in situ or multicentric lesions are found in these patients.

  • Clinical Manifestations Lung cancer gives rise to signs and symptoms caused by local tumor growth, invasion or obstruction of adjacent structures, growth in regional nodes through lymphatic spread, growth in distant metastatic sites after hematogenous dissemination, and remote effects of tumor products (paraneoplastic syndromes) (Chaps. 96 and 97). Although 5–15% of patients with lung cancer are identified while they are asymptomatic, usually as a result of a routine chest radiograph or through the use of screening CT scans, most patients present with some sign or symptom.

  • Chest radiographs and CT scans are needed to evaluate tumor size and nodal involvement; old radiographs are useful for comparison. CT scans of the thorax and upper abdomen are of use in the preoperative staging of NSCLC to detect mediastinal nodes and pleural extension and occult abdominal disease (e.g., liver, adrenal), and in planning curative radiation therapy. However, mediastinal nodal involvement should be documented histologically if the findings will influence therapeutic decisions.

  • Distinguishing Cardiogenic from Noncardiogenic Pulmonary Edema The history is essential for assessing the likelihood of underlying cardiac disease as well as for identification of one of the conditions associated with noncardiogenic pulmonary edema. The physical examination in cardiogenic pulmonary edema is notable for evidence of increased intracardiac pressures (S3 gallop, elevated jugular venous pulse, peripheral edema), and rales and/or wheezes on auscultation of the chest.

  • The idea for this book grew out of our experience in teaching pediatric radiology to clinicians and students. Clearly, there is a strong desire on the part of those taking care of children to familiarize themselves with the rudiments of the pediatric radiograph. While radiologists have primary responsibility for the interpretation of films, clinicians bring valuable insight and information. Often they present additional important data or ask searching questions that prompt a re-evaluation of the films so that a more appropriate diagnosis may be obtained....

  • The current global epidemic of pulmonary tuberculosis has highlighted the need for new screening tests that are rapid and accurate. The social burden of pulmonary tuberculosis has increased because many patients are also infected with human immunodeficiency virus (HIV), and the rates of multidrug-resistant tuberculosis are increasing.1 However, screening technology has not changed greatly during the past several decades. Many highburden countries depend upon sputum smears and chest radiographs, supplemented by cultures when resources permit.

  • Lymphomas Lymphoma in the small bowel may be primary or secondary. A diagnosis of a primary intestinal lymphoma requires histologic confirmation in a clinical setting in which palpable adenopathy and hepatosplenomegaly are absent and no evidence of lymphoma is seen on chest radiograph, CT scan, or peripheral blood smear or on bone marrow aspiration and biopsy. Symptoms referable to the small bowel are present, usually accompanied by an anatomically discernible lesion.

  • There are two situations in which the TST is not required. Applicants providing written documentation (with a health-care provider’s signature) of a TST reaction of 5 mm or greater of induration or applicants with a history of a severe reaction with blistering to a prior TST may be excluded from this requirement. Applicants in these two groups must undergo a chest radiograph. A verbal history of a positive TST reaction from the applicant is not acceptable.
