Background: Since the introduction of endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) of mediastinal lymph nodes, the incidence of histopathologically-confirmed sarcoidosis has increased. Methods: The electronic medical records of Chonnam National University (CNU) Hospital and CNU Hwasun Hospital (CNUHH) were searched for confirmed cases of sarcoidosis diagnosed between 1996 and 2014. Cases were selected using a combination of clinical, radiological, and pathological evidence. Of 115 cases with the relevant disease codes, 16 cases were excluded, as they had not been confirmed pathologically or had no definitive clinical features of sarcoidosis. Results: Among 99 cases of confirmed sarcoidosis, only nine patients were diagnosed with sarcoidosis before 2008; the rest were diagnosed from 2008 onward, after the introduction of EBUS-TBNA. EBUS-TBNA was used in 75.8% of patients, open surgical biopsy in 13.2%, and mediastinoscopic biopsy in 5.1%. At the time of diagnosis, 42.4% of sarcoidosis cases were at stage I, 55.6% at stage II, and 2% at stage III. Spontaneous remission of sarcoidosis was observed in 33.3% of cases, and stable disease in 37.4%; systemic steroid treatment was initiated in 23.2% of cases. Of the patients treated with systemic steroids, 69.6% showed improvement. The median duration of steroid treatment was 5 months. Conclusion: Following the introduction of EBUS-TBNA, the number of newly diagnosed sarcoidosis patients has increased. Clinical features of sarcoidosis were similar to those previously reported. Spontaneous remission occurred in about one-third of patients, while one-fourth of patients required systemic steroid treatment.

Molecular imaging is a rapidly growing field due to the advances in molecular biology and imaging technologies. With the introduction of imaging reporter genes into the cell, diverse cellular processes can be monitored, quantified and imaged non-invasively in vivo. These precesses include the gene expression, protein-protein interactions, signal transduction pathways, and monitoring of cells such as cancer cells, immune cells, and stem cells. In the near future, molecular imaging analysis will allow us to observe the incipience and progression of the disease. These will make us easier to give a diagnosis in the early stage of intractable diseases such as canter, neuro-degenerative disease, and immunological disorders. Additionally, molecular imaging method will be a valuable tool for the real-time evaluation of cells in molecular biology and the basic biological studies. As newer and more powerful molecular imaging tools become available, it will be necessary to corporate clinicians, molecular biologists and biochemists for the planning, interpretation, and application of these techniques to their fullest potential. in order for such a multidisciplinary team to be effective, it is essential that a common understanding of basic biochemical and molecular biologic techniques is achieved. Basic molecular techniques for molecular imaging methods are presented in this paper.
