Antibiotic-induced dysbiosis in the SCIME™ recapitulates microbial community diversity and metabolites modulation of disease.

Establishing The Context: Intestinal dysbiosis is a significant concern among dog owners, and the gut health of pets is an emerging research field. In this context, the Simulator of the Canine Intestinal Microbial Ecosystem (SCIME™) was recently developed and validated with data.

Stating The Purpose/introducing The Study: The current study presents a further application of this model by using amoxicillin and clavulanic acid to induce dysbiosis, aiming to provoke changes in microbial community and metabolite production, which are well-known markers of the disease .

Awake Breast Conservative Surgery: A Strategy to Shorten Surgical Waiting Lists During and Post COVID-19 Emergency.

Background/aim: SARS-CoV-2 with a dramatical worldwide spread, impacted greatly daily life and healthcare. In order to avoid delay in cancer treatment, many strategies and measures were implemented. The Awake breast surgery was a strategy implemented in our Unit during the pandemic, aimed to reduce operatory room occupancy and increase the number of procedures performed during the daily surgical session.

Combined surgical approach retromandibular and intraoral to subcondylar mandibular fractures.

Background: Condylar and subcondylar fractures are very common and account for at least one third of all mandibular fractures. In literature, little agreement exists about the management of extracapsular condylar and subcondylar fractures in adults. Some studies provide better results of occlusion, masticatory function, mouth opening, and bone morphology with surgical treatment.

Treatment of N in the upper maxillary tumors.

From 2002 to 2008, 86 patients have undergone surgical treatment of malignant upper maxillary tumors at the Maxillo-Facial Surgery Department, Tor Vergata University, Rome. All the N-positive patients at the time of the T therapy have undergone lymph node surgical emptying. In 6 patients, a laterocervical emptying was performed when laterocervical metastases were found.

Central giant cell granuloma of the jaws.

Central giant cell granuloma was classified by the World Health Organization in 2005 as a rarely aggressive idiopathic benign intraosseous lesion that occurs almost exclusively in the jaws. It occurs most frequently in young women (aged <30 y). This osteolytic lesion histologically consists of proliferation of fibrous tissue, hemorrhagic focuses, hemosiderin deposits, osteoclast-like giant cells, and reactive bone formation.

Intraosseous hemangiomas.

Intraosseous hemangiomas are classified as benign tumors of vascular nature. Some authors describe them as hamartomas. They originate and expand inside bone structures.

Reconstruction of premaxilla with fibula free flap.

The reconstruction of the maxilla after surgical excision of malignant neoplasms has always presented significant difficulties. The excision of the premaxillary region involves considerable aesthetic and functional problems and, thus, presents particular reconstructive difficulties. The difficulties in the reconstruction of this area are related to the advanced anterior position and to the structural complexity of the premaxilla.

Use of microvascular free flaps in the reconstruction of the anterior and middle skull base.

Different reconstruction techniques of the anterior and middle skull base as consequence of a defect after surgical treatment of neoplastic pathologies are described in the literature. The aim of the present study is to present our experience regarding the use of microvascular free flaps for reconstruction of the anterior or middle skull base after large defects caused by removal of malignant neoplasms. From 2000 to 2004, in the Department of Maxillo-Facial Surgery of the University of Rome "La Sapienza" and "Tor Vergata," 13 surgical procedures for reconstruction of anterior and middle skull base defects by free flaps were performed in 11 patients.

Surgical treatment of recurrent orbital hemangiopericytoma.

Hemangiopericytoma is a rare vascular tumor featuring the uncontrolled proliferation of pericytes. This tumor tends to develop in subcutaneous tissue and skeletal muscle. The localization of hemangiopericytoma in the orbit is particularly rare.

Surgical approach to the third area of the internal carotid artery through vertical osteotomy of the mandibular ramus: case report.

Internal carotid artery (ICA) reparative techniques are nowadays widely standardized in traumatic as well as degenerative pathological conditions; therefore, the greatest difficulty encountered in the treatment of lesions at the expense of the most distal segment of the ICA is not a result of the application of these techniques as much as the difficulty in obtaining adequate exposure of the vessel and a sufficiently wide surgical field. In the past, lesions localized more toward the skull were considered to be surgically unreachable. During the last 20 years, however, various techniques have been suggested and attempted for the exposure of this difficult area.
