Abstract

Background: Mediastinum includes the vital organs like the heart the major respiratory passages and the major vessels due to this vicinity, the masses of this area with malignant or benign etiology or cause systemic diseases such as metastatic malignancies or granulomatous reactions can be potentially fatal.

Materials and Methods: According to the priority of the problem, a ten years comprehensive retrospectively study of mediastinal masses in children was conducted In children medical Center (Tehran University) from the points of view of incidence, clinical manifestations and diagnostic and treating ways. Results &

Conclusion: In our study there were 34 patients from 1992-2002 who were reviewed. No differences between boys and girls with mediastinal masses were observrd. The most prevalence age for mediastinal tumors was form 5-10 years (38%). The most prevalent sign was fever (53%) and the most common symptom was coughing (44.4%). Basesd on this research, mediastinal masses have been the most prevalent finding in chest radiography (53.8%). CT-Scan with double contrast was recognized as the most common and easiest ways for diagnosing masses. Anterior masses were the most common finding in our study (41.7%). Most of these masses were removed by surgery and the most common operation in our patients was thoracotomy and removing the masses (61.7%). Lymphoma was the most common masses (35.2%) and masses with neural orgins occupy the second grade. According to available documents and with regard to mean follow up of patients in 3.2 years the rate of survival was 54%.

Abstract

} Background: Proper drainage of the mediastinal and pleural spaces following Off-Pump Coronary Artery Bypass (OPCAB) surgery is essential for the prevention of pleural and pericardial effusions, cardiac tamponade and late complications such as constrictive pericarditis. Drainage tubes themselves may induce some complications which can negatively affect the result of the surgery. In this study we assessed a new technique for chest drainage following OPCAB.
Methods: In this clinical trial, 171 patients were allocated to two groups. In the control group, the drainage technique included one drain in the left pleural cavity and another in the mediastinum, while in the case group the drainage technique included one drain in the left plural and one in the right pleural cavity.
Results: The amount of drainage in the case group was more than the control group (p=0.001). We found significant reductions in the incidence of arrhythmias in the case group (p=0.005). While one patient (1.2%) needed reoperation for bleeding control in the control group, no patients needed reexploration in the case group (p=0.497). The duration of hospital (p=0.022) and ICU (p=0.002) stays was shorter in the case group.
Conclusions: Based on the results of this study, changing the position of mediastinal drains in patients undergoing OPCAB surgery and shifting it to the right pleural cavity, reduces complications, such as arrhythmia and pericardial effusion, aside from establishing a better drainage.

Abstract

Background: The bronchopulmonary carcinoid tumor accounts for 1-2% of all adult malignancies of the lung and 20-30% of all carcinoid tumors. Cushing’s syndrome is the result of chronic exposure to increased concentration of exogenous or endo-genus cortisol hormone, and it is generally associated with central obesity, metabolic syndrome, and hypertension. Treatment is based on decreasing cortisol levels in the blood, through medical or surgical approaches. Surgery is considered the main treatment for ectopic ACTH-secreting tumors. Paraneoplastic Cushing’s syndrome due to bronchopulmonary carcinoid tumor is a rare clinical occurrence, which has been reported in only a few case reports and case series. An average of 71% of typical carcinoid tumors were found to be central. 79% of patients with a peripheral carcinoid tumor and evidence of mediastinal node enlargement are likely to have an atypical carcinoid.
Case Presentation: A 45 Years old male with a history of ectopic Cushing’s syndrome over the last two years was admitted to our department (Department of thoracic surgery, Teahran, Iran). He had a positive Octreotide scan of the hilar lymph nodes of the left lung at last evaluations. During the surgery, in the left lower lobe was resected (because a small nodule with tumoral appearance was seen in left lower lobe) with hilar and mediastinal lymph node dissection. Pathology indicated a typical carcinoid tumor with mediastinal lymph node metastasis. Plasma cortisol and ACTH were normalized following the surgery.
Conclusion: The present study reported a rare case of Cushing paraneoplastic syndrome with typical bronchopulmonary carcinoid tumor and N2 lymph node metastasis. The high prevalence of lymph node involvement confirms the aggressive nature of these tumors and warrants complete anatomic resection with radical lymphadenectomy.
