Alterations of pulmonary function in patients with inflammatory bowel diseases.

Aim: The aim of this study was to investigate the alterations of pulmonary function tests (PFTs) and their relationship with disease activity in inflammatory bowel diseases (IBDs).

Methods: Sixty-four IBD patients (31 Crohn's disease [CD] and 33 ulcerative colitis [UC]) and thirty healthy individuals (controls) were studied with regard to the following parameters of PFTs: Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), their ratio, mid-forced expiratory flow of 25-75% (FEF 25-75), residual volume, total lung capacity, and diffusing capacity of the lung for carbon monoxide (DLCO). The disease activity was calculated using the Crohn's Disease Activity Index for CD and Mayo Clinic Score for UC.

Primary extragastrointestinal stromal tumor of the pleura: A case report.

Gastrointestinal stromal tumors (GISTs) are the most common type of mesenchymal tumor of the gastrointestinal tract. The stomach and small intestine are the most common sites of occurrence. GISTs are mesenchymal neoplasms originating from the interstitial cells of Cajal (ICCs), and are characterized by positivity for cluster of differentiation (CD) 117, also known as proto-oncogene c-Kit.

Pulmonary manifestations of inflammatory bowel disease.

Extraintestinal manifestations of inflammatory bowel disease (IBD) are a systemic illness that may affect up to half of all patients. Among the extraintestinal manifestations of IBD, those involving the lungs are relatively rare and often overlooked. However, there is a wide array of such manifestations, spanning from airway disease to lung parenchymal disease, thromboembolic disease, pleural disease, enteric-pulmonary fistulas, pulmonary function test abnormalities, and adverse drug reactions.

A case of pulmonary sarcoidosis with endobronchial nodules.

Sarcoidosis is a multisystemic disorder of unknown cause that is characterized pathologically by noncaseating granulomas and predominantly affects the lungs and the lymphatic system, especially intrathoracically. Diagnosis is based on the association of a compatible clinical and radiological presentation, the presence of characteristic histopathological lesions and the exclusion of other potential causes of granuloma. Although the lungs and mediastinal lymph nodes are almost involved, endobronchial nodular lesions of sarcoidosis with lung involvements are rare.

Pulmonary manifestations of Crohn's disease.

Crohn's disease (CD) is a systemic illness with a constellation of extraintestinal manifestations affecting various organs. Of these extraintestinal manifestations of CD, those involving the lung are relatively rare. However, there is a wide array of lung manifestations, ranging from subclinical alterations, airway diseases and lung parenchymal diseases to pleural diseases and drug-related diseases.

Tracheobronchial nodules and pulmonary infiltrates in a patient with Crohn's disease.

Crohn's disease is a granulomatous systemic disorder of unknown etiology. Obvious pulmonary involvement is exceptional. Tracheal involvement in Crohn's disease is even more unusual, only a few cases have been reported to date.
