Elevated levels of anti inflammatory IL-10 and pro inflammatory IL-17 in malignant pleural effusions.

Background: Pleural effusions can be caused by highly different underlying diseases and are characterized by complex interactions of various local and circulating cells as well as numerous soluble parameters like interleukins (IL). Knowledge of this complex network can be helpful in order to make the differential diagnosis in known malignant pleural effusions and understand the underlying immunochemistry of each disease or condition.

Methods: We investigated immunoreactive concentrations of Interleukin 10 (IL-10) and Interleukin 17 (IL-17) in malignant pleural effusions and peripheral blood from patients with bronchial carcinomas and other carcinomas, excluding other conditions such as congestive heart failure (CHF) and pneumonias in twenty four (24) patients (9 men/15 women), 37-74 years (mean:61) with already diagnosed malignant pleural effusions applying the ELISA method.

Prenatal interventional and postnatal surgical therapy of extralobar pulmonary sequestration.

Extralobar sequestration, a discrete developmental mass of pulmonary parenchyma which is enclosed within a separate pleural envelope and has its own vascular supply, is recently diagnosed prenatally by ultrasonography. We report two male newborn babies, 10 days old, who prenatally underwent amnioperitoneal shunt, pleural drainage and laser ablation of the feeding artery. Both babies underwent thoracotomy on their 10th day of life, removal of the sequestration, ligation of the feeding vessel which remained patent despite laser treatment in the first case and drainage of a large pleural effusion in the second case.

Schwannoma of the vagus nerve, a rare middle mediastinal neurogenic tumor: case report.

Schwannoma originating from the vagus nerve within the mediastinum is a rare, usually benign tumor. A 44-year old male was presented with chest pain. Chest radiography, CT scan and MRI showed a well circumscribed mass, 5 x 4 cm located in the aortopulmonary window.

Serum levels of matrix metalloproteinases -1,-2,-3 and -9 in thoracic aortic diseases and acute myocardial ischemia.

Background: Matrix metalloproteinases (MMPs) constitute a family of zinc-dependent proteases (endopeptidases) whose catalytic action is the degradation of the extracellular matrix components. In addition, they play the major role in the degradation of collagen and in the process of tissue remodeling. The present clinical study investigated blood serum levels of metalloproteinases- 1, -2, -3 and -9 in patients with acute and chronic aortic dissection, thoracic aortic aneurysm and acute myocardial ischemia compared to healthy individuals.

Primary intrathoracic goiter: a rare and potentially serious entity.

Background: Here we review primary intrathoracic goiter (P-ITG), a rare but potentially serious congenital entity that is distinct from the much more common secondary intrathoracic goiter. The latter is an extension of cervical thyroid that descends within the mediastinum. In contrast, P-ITGs lack a connection with the cervical thyroid and their blood supply comes from intrathoracic vessels.
