Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia: Unusual presentation.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNEC) is an abnormal proliferation of pulmonary neuroendocrine cells that occur without underlying etiology. Here, we report a unique case of 55-year-old female with unusual presentation of DIPNECH and thymoma and on the background history of Crohn's disease that might point toward an autoimmune phenomenon. To the best of our knowledge, there were no previous reports of DIPNECH with either thymoma or Crohn's disease.

A study of chronic obstructive pulmonary disease-specific causes of osteoporosis with emphasis on the emphysema phenotype.

Background: Osteoporosis, the most common extra-pulmonary complication of chronic obstructive pulmonary disease (COPD), may be related to general causes or COPD-specific causes such as low forced expiratory volume in 1 s (FEV1) and hypoxia. A few studies reported that emphysema is an independent risk factor for osteoporosis. However, other workers considered the association to be confounded by low FEV1 and low body mass index (BMI) which cluster with emphysema.

Autoimmune symptoms in idiopathic pulmonary fibrosis: clinical significance.

Background And Aims: Information regarding autoimmune symptoms that do not meet the diagnostic criteria for connective tissue disease in patients with idiopathic pulmonary fibrosis (IPF) is limited. The aim of the present study was to investigate differences in the clinical characteristics and prognosis of IPF patients with and without autoimmune symptoms.

Methods: Consecutive patients diagnosed with IPF (N = 96) from January 2008 to December 2012 were included.

Traumatic aortic pseudoaneurysm.

A case report of a 5 years old male child, with a history of crash injury--(blunt trauma)--on the chest. Computed tomography (CT) scan, magnetic resonance imaging (MRI) of the chest revealed an aneurysm involving the arch of the aorta. An aortogram showed its exact extension.
