Neuroendocrine tumors of the gastrointestinal tract are rare entities. Functioning neuroendocrine tumors tend to present early because of hormoneinduced clinical symptoms, but detection of the primary lesion may be difficult owing to their small size. Neuroendocrine tumors are typically hypervascular and show enhancement after contrast administration on(More)
OBJECTIVE To determine if monocytes activated toward an angiogenic phenotype can be used to improve ischemic tissue healing in a rat skin flap model. STUDY DESIGN Prospective experimental study on Wistar rats. METHODS A caudally based 9 x 3 cm dorsal skin/panniculus carnosus flap was raised in 15 rats. The animals were divided into three groups: the(More)
Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract, with an overall incidence of approximately 2.2%. It is generally noted incidentally during laparotomy for management of other abdominal pathology. Complications are infrequent, developing in 4% of individuals with this abnormality, and are usually seen in childhood.(More)
Malignant hypertension may present with retinopathy, choroidopathy, and optic neuropathy. Flame-shaped retinal hemorrhages, an early finding, are due to smooth muscle necrosis and bleeding along the nerve fiber layer. Cotton-wool spots, or cytoid bodies, are not exudates, but rather are retinal infarcts. Hypertensive optic neuropathy is a late finding.(More)
Tissue-sectioning automation can be a resourceful tool in processing anatomical pathology specimens. The advantages of an automated system compared with traditional manual sectioning are the invariable thickness, uniform orientation and fewer tissue-sectioning artefacts. This short report presents the design of an automated tissue-sectioning device and(More)
