  • Dyspnea is the subjective sensation of uncomfortable or difficult breathing. Most patients report dyspnea as "shortness of breath." Patients report dyspnea when their breathing is excessive for the activity that they are doing. The sensation of dyspnea is produced by stimulation of both central and peripheral receptors that monitor respiratory muscle activity, hypoxia, hypercapnia, acid-base status, airway irritation, and changes in the pressure volume characteristics of the lung (i.e., j receptors in lung fibrosis or emphysema).

  • Approach to the Patient: Dyspnea (Fig. 33-3) In obtaining a history, the patient should be asked to describe in his/her own words what the discomfort feels like, as well as the effect of position, infections, and environmental stimuli on the dyspnea. Orthopnea is a common indicator of congestive heart failure, mechanical impairment of the diaphragm associated with obesity, or asthma triggered by esophageal reflux. Nocturnal dyspnea suggests congestive heart failure or asthma.

  • 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 first edition of Harrison’s Principles of Internal Medicine was published more than half a century ago. Over the decades, this textbook has evolved to reflect the continuing advances in the field of internal medicine and to meet the growing information base required of medical students and clinical practitioners. The users of this sixteenth edition of Harrison’s will not even have to open the volume to see that it marks a transition point in the book’s history. The new cover is only the most obvious indication of a new direction for Harrison’s.

  • Lewis Thomas, in his semi-autobiographical book The Youngest Science: Notes of a Medicine-Watcher, reminisced about his father, an internist in the early twentieth century who would sit by his patient, holding his hand while nature affected the cure. There was little else he could offer. Now, after almost 100 years, we have crossed vast frontiers in medicine, from hormones to the immune system to unlocking the promise of genomics. We have relegated diseases such as erythroblastosis to the history books and transformed AIDS from a death sentence to a chronic illness.

  • We evaluated the effects of previous pulmonary tuberculosis (TB) on the risk of obstructive lung disease. We analyzed population-based, the Second Korea National Health and Nutrition Examination Survey 2001. Participants underwent chest X-rays (CXR) and spirometry, and qualified radiologists interpreted the presence of TB lesion independently. A total of 3,687 underwent acceptable spirometry and CXR. Two hundreds and ninty four subjects had evidence of previous TB on CXR with no subjects having evidence of active disease.

  • This first chapter lays the groundwork for the rest of the discussions in this book. Of all the chapters, it covers the broadest range of topics; most of these are discussed further later in the book, but some of the basics—for example, the brief history of Oracle and the contents of the different “flavors” of the Oracle database products— are unique to this chapter. Oracle has grown from its humble beginnings as one of a number of databases avail- able in the 1970s to the market leader of today.

  • A pre-tested questionnaire was used by a trained counselor to obtain information on demographic characteristics, social and medical history from the subjects. Other important information about PTB such as previous BCG vaccination, contact with an index case and exposure to tuberculin skin test were also obtained. Laboratory investigations: Three early morning sputum were collected from each consenting asymptomatic subject. The samples were transported to TB laboratory of the department of Medical Microbiology and Parasitology, UCH, for immediate processing.

  • People concentrated in congregated systems, such as prisons, are important but often neglected reservoirs for TB transmission, and threaten those in the outside community. Therefore, this study was conducted to determine the prevalence of tuberculosis in a prison system of North Gondar Zone. Methods: An active case-finding survey in North Gondar Prison was carried out from March to May 2011. All prison inmates who had history of cough for at least a week were included in the study.

  • The objective of this study was to determine the prevalence of presumed ocular tuberculosis among diagnosed pulmonary tuberculosis patients in a tertiary government hospital in the Philippines and determine its common presentation in the population. This was a cross-sectional study in which 103 patients who were labeled to have active pulmonary tuberculosis underwent history and ocular examination prior to anti-tubercular therapy. The diagnosis of presumed ocular tuberculosis was made when clinical signs of tuberculosis (TB) uveitis were found in the participants.

  • They observed that the use of well defined symptoms as diagnostic tool, even in resource limited settings, may improve the chances of diagnosing childhood pulmonary tuberculosis. Fourie et al observed some clinical criteria thought to be most relevant as predictors of tuberculosis in children . These criteria include history of contact with a case of tuberculosis, positive skin test, persistent cough, low weight for age, and unexplained/ prolonged fever.

  • In our study, we aimed to determine the validity of diagnostic methods for tuberculosis. Eighty-one people suspected to have tuberculosis were included in the study. The validity of the applied methods for the diagnosis of tuberculosis tuberculin skin test (TST), sputum smear, and used in diagnostic chest X-ray findings (CXR), clinical features and history were evaluated as culture was considered the reference test. Included in the study of 81 people (54 males 27 females) mean age was determined as 45.04 ± 18.69.

  • All the necessary information and data were collected from both medical records of the patients and special questionnaires that were designed by our staff in 1996 for this purpose. Statistical analysis was carried out descriptively by using frequency and percentage. Presence of TB in the patients was confirmed by identifying the microorganism in the tissues detecting pathological changes in favour of TB and/or having past history of pulmonary TB associated with its anatomical complications such as cavitation, bronchiectasis, and bronchial stenosis.

  • Approach to the Patient: Hemoptysis The history is extremely valuable. Hemoptysis that is described as bloodstreaking of mucopurulent or purulent sputum often suggests bronchitis. Chronic production of sputum with a recent change in quantity or appearance favors an acute exacerbation of chronic bronchitis. Fever or chills accompanying bloodstreaked purulent sputum suggests pneumonia, whereas a putrid smell to the sputum raises the possibility of lung abscess. When sputum production has been chronic and copious, the diagnosis of bronchiectasis should be considered.
