Ghost cell (GC) differentiation within AF is extremely rare. There are only seven cases in the international literature in which ghost cells are found in AF.

Rare and life-threatening complication after an attempted lower third molar extraction: Lemierre syndrome.

Lemierre's syndrome is also known as the forgotten disease, and is a rare but life-threatening complication that can arise after surgical extractions of infected mandibular third molars. Owing to its rarity, oral and maxillofacial surgeons might not immediately recognise or can underestimate the pathological signs, and consequently do not apply the appropriate therapy to treat the syndrome. Here, we report on the occurrence and management of a case of Lemierre's syndrome, where the complications affected the right sigmoid sinus.

Bilateral Central Giant Cell Granuloma of the mandibular angle in three females from the same family.

In literature there are few reports about multiple CGCG. But this is the first report of bilateral CGCG of the mandibular angles in three females from the same family.This report describes three cases of females from the same family - a mother and two young daughters - with bilateral CGCG in their jaw angles.

Giant and Very Large Intracranial Aneurysms: Surgical Strategies and Special Issues.

Giant intracranial aneurysms (GIAs) and very large intracranial aneurysms (VLAs) have a poor natural history because of a high incidence of bleeding and strokes. These lesions always represent a great challenge for neurosurgeons and interventional neuroradiologists because of some peculiar intrinsic features such as size, angioarchitecture, wide neck, mass effect, intraluminal thrombosis, atherosclerotic changes, involvement of branches and perforators, and a frequent need to perform revascularization procedures. The results of a cumulative surgical series of 75 VLAs and GIAs are reported.

Endoscope-Assisted Microneurosurgery for Intracranial Aneurysms: Operative Technique, Reliability, and Feasibility Based on 14 Years of Personal Experience.

Endoscope-assisted microneurosurgery (EAM) combines endoscopic and microsurgical techniques for the treatment of deeply located intracranial lesions. During aneurysm surgery, endoscopic assistance may aid in the visualization of perforating arteries, especially when minimally invasive approaches are used. Between 2002 and 2015, a total of 183 patients with 208 intracranial aneurysms were surgically treated in our department.

Engraftment, neuroglial transdifferentiation and behavioral recovery after complete spinal cord transection in rats.

Background: Proof of the efficacy and safety of a xenogeneic mesenchymal stem cell (MSCs) transplant for spinal cord injury (SCI) may theoretically widen the spectrum of possible grafts for neuroregeneration.

Methods: Twenty rats were submitted to complete spinal cord transection. Ovine bone marrow MSCs, retrovirally transfected with red fluorescent protein and not previously induced for neuroglial differentiation, were applied in 10 study rats (MSCG).

Scanning electron microscopy and microbiological approaches for the evaluation of salivary microorganisms behaviour on anatase titanium surfaces: In vitro study.

Implantology research framed the implant surface as a key element for a good and sustainable osseointegration of an implant fixture. The aim of this study was to analyze the antibacterial properties of anatase-coated titanium healing screws through microbiological and scanning electron microscopy. The comparison of the bacterial colonies growth between the anatase-coated titanium healing screws and non-coated titanium healing screws showed comparable antibacterial properties, without significant statistical differences.

Cervical injury related to mandibular fractures. A retrospective study of 315 cases.

Objective To define the association between mandibular fractures and alterations of the cranio-atlo-axial joint (CAAJ). Methods 315 cases of displaced mandibular fractures were retrospectively evaluated by CT scan and cervical X-ray for associated alterations of the CAAJ. Statistical analysis employed the chi-square and Cohen's kappa coefficient.

Cortical aneurysms of the middle cerebral artery: A review of the literature.

Background: Middle cerebral artery (MCA) aneurysms constitute from 18-40% of all intracranial aneurysms. They are mainly found in the proximal and bifurcation tracts and only in the 1.1-1.

Systemic sclerosis associated with colliquative necrosis in the cerebellum.

Background: The scleroderma is a complex autoimmune collagen disorder that can affect many organs simultaneously, as it occurs in the systemic sclerosis (SS), or only the skin, as it occurs in the localized scleroderma (LS). The neurological presentation is extremely uncommon, and even more uncommon are the symptoms of the scleroderma in the cerebellum.
