A Case Report of Primary Mediastinal Liposarcoma: A Rare Mediastinal Tumor.

Liposarcomas account for about 20% of all sarcomas among mesenchymal neoplasms. Myxomatous liposarcoma is a rare mediastinal tumor that seems the same as other lung disorders. The most common presenting symptoms are chest pain, dyspnea, and dysphagia.

A Case Report of Inflammatory Myofibroblastic Tumor: A Rare Benign Lung Tumor.

Inflammatory myofibroblastic tumors (IMTs) of the lung are a rare type of mesenchymal tumors that tend to occur more in the lungs of children. They are extremely rare in adults. IMTs require extensive pulmonary resection because they are commonly locally invasive.

Pleural and serum markers for diagnosis of malignant pleural effusion.

Background: Differentiation between benign and malignant exudative pleural effusion remains a clinical challenge. Recently, several markers have been reported to increase the diagnostic accuracy of malignant pleural effusion, with controversial results.

Methods: Patients with exudative pleural effusion were divided into 2 groups: a malignant pleural effusion group (39 patients) diagnosed by malignant cells in pleural fluid cytology or by malignant infiltration of the pleura on pleural biopsy, and a benign pleural effusion group (51 patients) with neither malignant cells in pleural fluid cytology nor malignant infiltration of the pleura on pleural biopsy.

Temporary Epicardial Pacing After Valve Replacement: Incidence And Predictors.

Temporary pacemaker wires are usually inserted in patients after valve replacement and may be beneficial for optimizing myocardial function in patients that develop postoperative hemodynamically significant arrhythmias [Elmi 2002]. Indications for temporary cardiac pacing (TCP) are atrial, ventricular or atrioventricular pacing for bradyarrhythmias and for management of both atrial and ventricular tachyarrhythmias [De Belder 1990; Liebold 1998].Pacemaker wires have two ends - one end has a small needle, which is passed into the myocardial surface, then is cut off.

Indicators for surgical intervention in thoracic empyema in children.

Objectives: To determine predictors for surgical intervention of thoracic empyema in children, and its associated morbidity.

Methods: We conducted a retrospective review of medical records of children with empyema thoracis admitted in the Maternity and Children Hospital, Al Madinah Al Munawwarah, Saudi Arabia between January 2007 and January 2012. The data extracted included: socio-demographic data, clinical data, method of treatment, and follow up data.

Effect of body mass index on early clinical outcomes after cardiac surgery.

Background: there are several reports on the outcomes of cardiac surgery in relation to body mass index. Some concluded that obesity did not increase morbidity or mortality after cardiac surgery, whereas others demonstrated that obesity was a predictor of both morbidity and mortality.

Methods: this was a retrospective study of 3370 adult patients undergoing cardiac surgery.

Pleural tent for decreasing air leak following upper lobectomy: a prospective randomised trial.

Objective: Prolonged air leak is still one of the most frequent complications after pulmonary resections, particularly upper lobectomy. This study aimed at evaluating the efficacy of pleural tenting in decreasing air leak after upper lobectomy.

Methods: This was a prospective randomised study of 48 patients who had upper lobectomy.

Intercostal muscle flap for decreasing pain after thoracotomy: a prospective randomized trial.

Background: Intercostal nerve damage is often suggested to be the cause of pain after thoracotomy.

Methods: This was a prospective randomized study of 120 patients who had posterolateral thoracotomy. They were equally divided into two groups, the first in which intercostal muscle flap and intracostal sutures were used, and the other group in which the usual pericostal sutures were used.
