1.  Spontaneous resolution of paraparesis because of acute spontaneous thoracolumbar epidural hematoma 
Symptomatic spontaneous spinal epidural hematoma(SSEH) is an uncommon cause of cord compression that commonly is considered an indication for emergent surgical decompression. We aimed to investigate a patient with a SSEH that completely resolved clinically and radiographically, without surgical treatment. The patient presented three days after the sudden onset of back pain, numbness, and weakness. Magnetic Resonance Imaging (MRI) revealed a posterior thoracolumbar epidural hematoma extending from the level of T10 to L2 with significant cord compression. Decompression was recommended but he refused surgery and was managed conservatively. One month later weakness totally recovered and hematoma was absent on MRI.

4.  Jejunal invagination in an adult caused by inflammatory fibroid polyp: a case report 
Cases Journal  2009;2:6435.
Invagination is a rare cause of mechanical intestinal obstruction in adults, but half of their causes are malignant. A diagnosis of invagination in an adult patient strongly suggests presence of a malignant pathology. Moreover some benign conditions may resemble malignant disorders like inflammatory fibroid polyp. Inflammatory fibroid polyps are rare benign lesions of uncertain origin that may occur in various parts of the gastrointestinal tract, with gastric antrum being the most common site, followed by the small intestine.
Case presentation
A 31-year old male patient was admitted to our emergency department few hours after complaints of nausea and vomiting. Abdominal examination revealed distension and clanging intestinal sounds. Computed tomography showed intestinal obstruction without an obvious cause. The patient underwent diagnostic laparotomy. In this process, approximately 10 cm of invaginated mid-jejunal segment was seen. The pathologic segment was resected and end-to-end anastomosis was performed. The patient was discharged without any complication.
Although IFP is seen very rarely in adults, it is one of the probable diagnoses that should be considered in obstructive tumors of the small intestine causing invagination.

5.  Ex Vivo Resuscitation of Adult Pig Hearts 
Texas Heart Institute Journal  2003;30(2):121-127.
One possible way to expand the human heart donor pool is to include non-heart-beating human donors. To begin validating this approach, we developed an ex vivo cardiac perfusion circuit to support large mammalian hearts in Langendorff mode and beating-ejecting mode and to assess and improve their ischemic tolerance.
In vivo hemodynamic data and heparinized blood (4.0 ± 0.5 L) were collected from 6 anesthetized pigs. Hearts were isolated and connected to a recirculating perfusion circuit primed with autologous buffered blood (pH, 7.40). After retrograde aortic perfusion in Langendorff mode, the left atrium was gravity-filled at 10–20 mmHg, and the left ventricle began to eject against a compliance chamber in series with a systemic reservoir set to a hydraulic afterload of 100–120 mmHg. Left ventricular function was restored and maintained in all 6 hearts for 30 min. Cardiac output, myocardial oxygen consumption, stroke work, aortic pressure, left atrial pressure, and heart rate were measured. The mean myocardial oxygen consumption was 4.8 ± 2.7 mL/min/100 g (95.8% of in vivo value); and mean stroke work, 5.3 ± 1.1 g · m/100 g (58.95% of in vivo value). One resuscitated heart was exposed to 30 min of normothermic ischemic arrest, then flushed with Celsio® and re-resuscitated.
The ex vivo perfusion method described herein restored left ventricular ejection function and allowed assessment of ischemic tolerance in large mammalian hearts, potentially a 1st step toward including non-heart-beating human donors in the human donor pool. (Tex Heart Inst J 2003;30:121–7)
