acute aortic dissection (aad) is the most frequent catastrophic event of the aorta; it occurs nearly three times as frequently as the rupture of abdominal aortic aneurysm . sixty percent of dissection cases are classified as proximal or type a and 40% as distal or type b, according to the stanford classification. the most frequent causes of death in acute type b dissection are aortic rupture an...

Samuel David Gross (1805–1884) (Fig. 1), a native of Easton, Pennsylvania, and a graduate of Jeff erson Medical College in Philadelphia, wrote his fi rst book [1] in 1828, just two years after he received his M.D. degree. Th e book, which was the fi rst American treatise on orthopedic pathology and surgery, was an instant success, but Gross’s attempt to establish a surgical practice was a failu...

immediate and late post operative complications or radical neck dissection were discussed. preventive measures and the treatment of each were mentioned briefly. our 10 years experience with complications or neck dissection in the cancer institute was presented.

The study of myology is relevant for both functional understanding and distinguishing different species. The pine marten (Martes martes) is a small carnivore found in Europe and Western Asia and belongs to the Mustelidae family. For the purpose of this study, fresh a carcass which was found in the hunters' trap, was brought to the anatomy hall of veterinary faculty, for anatomical studies. Afte...

Malignant peripheral nerve sheath tumor (MPNST) is exceedingly rare to occur intracerebrally. The incidence of this subtype 0.001%. Their typical origin from nerves the limbs, trunk, and lumbar brachial plexuses. It carries a poor prognosis despite aggressive management due high chances local recurrence. We present case MPNST occurring intracerebrally in 60-year-old male patient. Imaging showed...

We analyze a generalized Gross-Pitaevskii (GP) equation involving a paraboloidal trap potential in D space dimensions and generalized to a nonlinearity of order 2n+1. For attractive coupling constants collapse of the particle density occurs for Dn>/=2 and typically to a delta function centered at the origin of the trap. By introducing a special variable for the spherically symmetric solutions, ...

Aortic dissection occurs when a tear develops in the wall of the aorta, which is rare in the young population. This fatal disorder is hard to diagnose, especially in young patients. We present the case of aortic dissection in a 15-year-old boy referred to the Emergency Department of Yazd University of Medical Sciences in November 2015. The patient presented to our department with sudden acute c...

Aortic coarctation is a rare but dangerous condition. Presence of aortic dissection in addition to coarctation is significantly rarer and more life-threatening. Here, we present a case of acute inferior MI due to aortic dissection complicating a native aortic coarctation. A 17-year-old boy was admitted to our emergency department due to severe chest pain and loss of consciousness. His ele...

introduction: aortic dissection is a rare condition in young women and usually related with congenital anomalies of aorta and connective tissue disorders. we reported a 34-year-old postpartum woman with aortic dissection. case presentation: the patient complained of respiratory distress and weakness with no abdominal pain or chest pain 20 days after delivery and had no history of hypertension d...

spontaneous coronary artery dissection is a rare cause of acute coronary syndrome and sudden cardiac death. we report coronary artery dissection in a 36-year-old woman with retrosternal chest pain 2 weeks after abortion. electrocardiography showed st elevation in leads v2-v4 and st depression in the inferior leads. lab data were normal. cardiac catheterization showed a suspicious thrombotic les...
