Mucosa-Associated Lymphoid Tissue Lymphoma of the Lung With Cold-reacting Autoantibody-mediated Hemolytic Anemia – Discussion
The concept of MALToma was first described bv Isaacson and Wright2 in a patient suffering from immunoproliferative intestinal disease and low-grade primary В cell lymphoma of the stomach in 1983. The distinct clinicopathologic entity was later extended to include low-grade В cell lymphoma arising from other mucosal organs including the bronchus, salivary gland, thyroid gland, […]
Mucosa-Associated Lymphoid Tissue Lymphoma of the Lung With Cold-reacting Autoantibody-mediated Hemolytic Anemia – Case Report
The primary mucosa-associated lymphoid tissue lymphoma (MALToma) of the lung is a rare low-grade В cell lymphoma arising from bronchus-associated lymphoid tissue which had been regarded as pseudolymphoma. It has characteristic histologic findings with monoclonal В cells of centrocytelike lymphoid cells and a lymphoepithelial lesion. This is a case report of MALToma of the lung […]
Comparison of Cardiac Pacing Modes in Patients With Chronic Obstructive Pulmonary Disease – Discussion
Dyspnea with exertion is a commonly recognized complaint in patients with lung disease. An increasing perception of shortness of breath with exercise is consistent with severe lung disease and frequently results in a fear of exertion that not only limits any activity requiring exertion, but daily living activities as well. The limitation of physical activities […]
Comparison of Cardiac Pacing Modes in Patients With Chronic Obstructive Pulmonary Disease – Results
All patients with COPD had sinus node dysfunction, including four with chronotropic incompetence. All had AV nodal disease, three 3° AV block, four 1° AV block, and one 2° AV block. Three of these patients had documented retrograde conduction and a history of pacemaker syndrome in the WI mode. However, only one of these patients […]
Comparison of Cardiac Pacing Modes in Patients With Chronic Obstructive Pulmonary Disease – Methods
Spirometry was used to evaluate baseline lung function for each patient. This was performed prior to exercise, with the patient standing. Patients were required to perform three reproducible forced expiratory and inspiratory maneuvers. All patients were then evaluated with paired exercise testing using the Chronotropic Assessment Exercise Protocol Pulmonary gas exchange, exercise duration, heart rate, […]
Comparison of Cardiac Pacing Modes in Patients With Chronic Obstructive Pulmonary Disease – Patient Population
Limitations in exercise tolerance are a common manifestation of patients with chronic lung disease. Compromised pulmonary mechanics limit the ability of the lungs to respond to increasing oxygen demands. This leaves these patients dependent on other mechanisms to deliver available oxygen to the tissues to support the metabolic demands of exercise. Optimizing cardiac output is, […]
The Third Epidemic—Multidrug-Resistant Tuberculosis: Discussion
During the past decade, the incidences of HIV infection and ТВ have ascended to epidemic proportions in several major US cities. At Bellevue Hospital Center in Manhattan, the incidence of MDR-TB has increased sevenfold in 1991 as compared with any of the previous 20 years. buy antibiotics online Several case series have been reported by […]
