Background: Although infectious diseases are the most common sources for the fever of unknown origin (FUO), but the spectrum of infectious diseases is changing overtime. The purpose of the study was to define the clinical spectrum and changing the pattern of FUO.Methods: This existing data based study was undertaken from 2007 to 2011. One hundred-six patients fulfilling the modified criteria fo...

Despite the different pathological features of COPD and asthma, two diseases often present similar clinical characteristics. In both diseases, patients suffer from exertional dyspnea other medical conditions. Pulmonary rehabilitation in has been reported to have various effects, including reduced dyspnea, improved quality life, increased aerobic capacity. Although there are few results on pulmo...

according to significant improvements in the tissue engineering field over the past several years, lung tissue cells have recently attracted more attention due to the high prevalence and diversity in related diseases. however, selection of an appropriate cell type, screening of suitable conditions for growth and proliferation, as well as subsequent implantation into the body to repair and regen...

Pulmonary hypertension has been identified as one of the well known life threatening complications of connective tissue diseases. In patients with connective tissue diseases pulmonary hypertension occurs with little or no evidence of parenchymal lung disease. As in primary pulmonary hypertension, the pathophysiology is unknown but the clinical course and pathological findings are similar. Scler...

background in spite of recent advents, and novel improvements in the diagnosis and treatment of pulmonary tuberculosis (tb), definitive diagnosis of pulmonary tb in children is problematic. therefore, measurement of the serum level of adenosine deaminase (ada) was later introduced as a helpful marker for the diagnosis of tb. objectives the purpose of this study was to determine the usefulness o...

Pulmonary hypertension (PH) often complicates the course of patients with advanced lung disease, and it is associated with a worse prognosis. Per the recent classification of pulmonary hypertensive disorders, PH due to lung disease is considered as a separate category within a group of disorders that was previously referred to as "secondary" PH. Among the lung diseases associated with PH, the i...

Background and Purpose: Pneumocystis pneumonia, caused by Pneumocystis jirovecii, is a fatal disease threatening patients with AIDS or immunosuppression. Assessment of colonization in these patients is of great significance, since it can lead to severe pulmonary disorders. Considering the scarcity of published reports on Pneumocystis jirovecii isolates from patients in Mashhad, Iran, we aimed t...

Pulmonary hypertension (PH) is a haemodynamic and pathophysiological condition defined as increase in mean pulmonary arterial pressure ≥ 25 mmHg at rest as assessed by right heart catheterization (RHC). It can be due to a primary elevation of pressure in the pulmonary arterial system alone (pulmonary arterial hypertension), or secondary to elevations of pressure in the pulmonary venous and capi...
