We report a case of intrathoracic extramedullary hematopoiesis associated with hemolytic anemia. While the paravertebral localization of the lesions demonstrated on CT and MRI was suspicious of intrathoracic extramedullary hematopoiesis, In-111 chloride and Tc-99m Sn colloid bone marrow scintigraphies showing a bone marrow element of the lesion were useful to confirm the diagnosis.

Intrathoracic goiter is commonly located in the anterior mediastinum. Here we report a case of a 58-year-old Chinese male in whom we successfully removed the intrathoracic goiter and eased his dyspnea by a right posterolateral thoracotomy approach. Posterior mediastinal thyroid goiter with mediastinal compressive symptoms is an indication of surgery.

Mitral valve closure during cardiopulmonary resuscitation may result from direct cardiac compression. An alternative hypothesis is that with a rise in intrathoracic pressure, mitral valve closure can occur but may be influenced by whether the lungs are inflated or deflated. To test this hypothesis, we placed a large-bore cannula into the thoraces of 11 dogs. Intrathoracic pressure was changed b...

Although the influence of the Valsalva maneuver on the heart and circulatory system has been investigated, the mechanism of intrathoracic pressure influencing cardiovascular function is unclear. To test our hypothesis that the interaction between the anatomy-determined partially-intrathoracic system and the fully-intrathoracic system might explain those issues and help to disclose the mechanism...

Intrathoracic lymph node metastases in patients with extrathoracic malignancies are a common clinical manifestation. Several studies evaluating intrathoracic lymph node metastases in patients with extrathoracic malignancy by using the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) have been reported. The objective of this meta-analysis is to investigate the diagnos...

BACKGROUND Cardiac resynchronization therapy defibrillator (CRT-D) devices are now capable of monitoring changes in intrathoracic impedance. Intrathoracic impedance monitoring resulting in a fluid index threshold crossing has been proven to predict heart failure (HF) exacerbations. We retrospectively investigated the relationship between changes in intrathoracic impedance and the occurrence of ...

Intrathoracic tumours in patients with Von Recklinghausen's disease have been widely reported, but there are very few cases of reported intrathoracic giant benign neurofibroma with marked mediastinal shift and superior vena cava syndrome. Patients that present with this pathology should be adequately investigated. Surgical resection has been considered curative.

Imaged thoracoscopic surgery is a technique utilized to operate on the intrathoracic organs without making a formal thoracotomy incision. Eleven patients underwent lung biopsy with this procedure and each had markedly reduced postoperative pain. Each patient resumed preoperative activity levels within one week of discharge from the hospital. Besides thoracotomy and thoracoscopy, imaged thoracos...

OBJECTIVE To assess mortality related to exposure to tuberculosis (TB) at home among children in urban areas of Guinea-Bissau. METHODS In four suburban areas included in the demographic surveillance system of the Bandim Health Project in Bissau, the mortality of children aged <5 years living with an adult with TB was compared with the mortality of children in the general population. RESULTS...

Despite the widespread clinical appliciktion of cardiopulmonary resuscitation (CPR), the mechanism responsible for blood flow during this maneuver remains undefined, although it has been assumed that blood is squeezed from the heart by direct compression of the sternum. We studied the hemodynamics of CPR in 15 arrested dogs. During chest compression, pressures in the left ventricle, aorta, righ...
