Morgagni's Spine Fractures-Dislocation per Anatomen Indagatis: Since the Dawn of modern medicine a Taxonomy and Pathomorphology problem.
The aim of this study is to retrieve and bring back to light a part of the astonishing and painstaking work of the legendary Italian father of modern pathology Giovanni Battista Morgagni, concerning one of most discussed topics in spine surgery: spine fractures-dislocations. All the excerpts selected for this study are contained in De sedibus et causis morborum per anatomen indagatis, the summa maxima of the entire production of Morgagni. This treatise encloses the enormous experience of Morgagni in anatomic dissections and pathologic investigations. With the aid of a strict dissection and description methodology, Morgagni identified and described many of the most important aspects of spinal fractures-dislocations, from the importance of the mechanism of injury, to the relevance of ligamentous complex, or the risk of posttraumatic kyphosis and the clinical expression of spinal cord injury.

Case Reports
Intradural Carcinoid Tumor Found in a Patient with No History of Cancer: A Case Report.
Carcinoid tumors are rare neoplasms that often arise from the gastrointestinal or respiratory tracts. They often metastasize to bone tissue and pancreatic and hepatic sites. The central nervous system and most specifically the spinal cord are rarely involved. Primary carcinoid tumors of the central nervous system are even rarer. ⋯ Carcinoid tumors of the central nervous system are extremely rare, but they should remain in the differential diagnosis for patients experiencing extremity weakness and back or neck pain with an intradural mass and no primary source of the tumor identified or other manifestations of a primary tumor.

Subthalamic deep brain stimulation (DBS) is a well-established treatment for patients with Parkinson's disease who suffer from severe motor fluctuations. The most common surgery-related complications are temporary confusion, bleedings, infections, and seizures. Seizures have been described to occur mainly around the time of the implantation of electrodes and, at present, the best established risk factors for seizures in association with DBS surgery are bleedings. A postoperative status epilepticus as complication of DBS surgery has never been described before. ⋯ This is a first report on a status epilepticus after DBS surgery, implicating that this complication has to be considered as differential diagnosis in somnolent patients after this operation.

The aim of our study was to determine the presence of heterotopic ossifications (HO) in a series of patients with cervical disk arthroplasty treated with different type of prosthesis, as well as to analyze the most suitable systems for diagnosis. ⋯ Our results showed that, although cervical disks provide optimal mid-term results, the incidence of HO seems to increase with time. Long term studies, with a larger sample size should be conducted to evaluate the appearance of HO and cervical motion after total disk replacement.

Daughter sac formation related to blood inflow jet in an intracranial aneurysm: A case study.
We performed a hemodynamic study of an intracranial aneurysm with a newly developed daughter sac during observation to investigate the role of hemodynamics on the formation of a daughter sac. ⋯ Blood inflow jet caused local elevation of pressure, and the formation of the daughter sac occurred at the site with high pressure but without the surrounding structure, which may cancel the perpendicular wall tension.
