Salivary gland cancer in Southern Brazil: a prognostic study of 107 cases.
2020
Background Salivary gland cancers (SGC) represent an uncommon group of heterogeneous tumors. We performed a retrospective survey of SGC diagnosed in a reference center for treatment of malignant tumors from the south of Brazil aiming to determine the prognostic value of demographic, clinic and pathologic features. Material and Methods Cases diagnosed as SGC between 2006 and 2016 were retrospectively collected. Medical records were examined to extract demographic, clinic, pathologic and follow-up information. Results One-hundred and seven cases of SGC were identified. The most common SGC were mucoepidermoid carcinoma (MEC) (n = 39) followed by adenoid cystic carcinoma (AdCC) (n = 29). Among …
Predictors of Central Compartment Involvement in Patients with Positive Lateral Cervical Lymph Nodes According to Clinical and/or Ultrasound Evaluati…
2021
Lymph node neck metastases are frequent in papillary thyroid carcinoma (PTC). Current guidelines state, on a weak level of evidence, that level VI dissection is mandatory in the presence of latero-cervical metastases. The aim of our study is to evaluate predictive factors for the absence of level VI involvement despite the presence of metastases to the lateral cervical stations in PTC. Eighty-eight patients operated for PTC with level II–V metastases were retrospectively enrolled in the study. Demographics, thyroid function, autoimmunity, nodule size and site, cancer variant, multifocality, Bethesda and EU-TIRADS, number of central and lateral lymph nodes removed, number of positive lymph n…
Botulinum Toxin A for Oral Cavity Cancer Patients: In Microsurgical Patients BTX Injections in Major Salivary Glands Temporarily Reduce Salivary Prod…
2012
Abstract: In patients suffering from oral cavity cancer surgical treatment is complex because it is necessary to remove carcinoma and lymph node metastasis (through a radical unilateral or bilateral neck dissection) and to reconstruct the affected area by means of free flaps. The saliva stagnation in the post-operative period is a risk factor with regard to local complications. Minor complications related to saliva stagnation (such as tissue maceration and wound dehiscence) could become major complications compromising the surgery or the reconstructive outcome. In fact the formation of oro-cutaneous fistula may cause infection, failure of the free flap, or the patient’s death with carotid b…
A DISSECTION'S GUIDE TO HUMAN ABDOMINAL CAVITY
2020
The purpose of this article is to show the abdominal cavity's dissection method. In the summer of 2018 a group of students from the University of Palermo, who had already taken the anatomy exam and had good knowledege of English, went for a period of two weeks to do a dissection course at the University of malta. The students dissected skin, subcutaneously, muscle layers, parietal peritoneum and abdominal organs. this works proves to be a small dissection guide for young medical students who want to learn the main bases of dissection and important information for topographical anatomy.
A BRIEF ANATOMO-SURGICAL DISSECTION GUIDE TO HUMAN LOWER LIMB: RESULTS OF THE COLLABORATION BETWEEN THE UNIVERSITY OF PALERMO AND THE UNIVERSITY OF M…
2020
The aim of this Article is to show methods for dissection of the lower limb. In the summer 2017 a group of students at the University of Palermo that have already passed the exam of Human Anatomy took a 4 weeks dissection course at the University of Malta - School of Medicine. The students were provided with a dissection kit, video recording equipment and cameras for taking pictures. This paper presents the results of the dissection course and a small and simple guide to young students and medical doctors who want to learn the bases of lower limb dissection.
Periscope endograft technique to revascularize the left subclavian artery during thoracic endovascular aortic repair.
2013
Purpose: To present early and midterm results of the periscope endograft (PG) technique to maintain left subclavian artery (LSA) blood flow in thoracic endovascular aortic repairs (TEVAR) involving zone 3. Methods: From April 2010 to January 2013, 14 consecutive high-risk patients (11 men; mean age 7068 years, range 56–87) underwent TEVAR with the PG technique for 10 thoracic aortic aneurysms (TAA), 2 traumatic aortic ruptures, and 2 aortic dissections without a suitable landing zone (.2 cm distal to the LSA). Five procedures were performed emergently for rupture (3 TAAs and the 2 trauma cases). Two patients had a periscope deployed in an aberrant right subclavian artery. The periscope endo…
Outcome Analysis From a Multicenter Registry on Unibody Stent-Graft System for the Treatment of Spontaneous Infrarenal Acute Aortic Syndrome (MURUSSI…
2022
Purpose: This study reports the outcomes from a Multicenter Registry on unibody stent-graft system for the treatment of spontaneous infrarenal acute aortic syndrome (MURUSSIAS registry). Materials and methods: The retrospective MURUSSIAS registry included spontaneous infrarenal acute aortic dissection (IAAS) managed with the unibody stent-graft system (AFX endovascular AAA system; Endologix Inc., Irvine, California) outside the current instruction for use. IAAS considered aortic dissection (AD), intramural hematoma (IMH), and penetrating aortic ulcer (PAU). Indications to IAAS treatment were symptoms, associated dilated abdominal aorta (>3 cm), rapidly-growing (>0.5 cm/6 months) aorta…
Use-wear analysis applied in a dissected palimpsest at the Middle Palaeolithic site of El Salt (eastern Iberia): working with lithic tools in a narro…

Los análisis de uso-desgaste son muy útiles para aumentar el conocimiento sobre las dinámicas económicas y de subsistencia llevadas a cabo por los neandertales. En términos generales, los resultados funcionales provienen tradicionalmente del análisis de herramientas pertenecientes a unidades estratigráficas cuya escala temporal se refiere al tiempo geológico. Esto se debe a que muchos yacimientos neandertales son palimpsestos de ocupaciones reiteradas a lo largo del tiempo, que deben ser diseccionadas para acercarnos a la escala temporal humana. En la unidad estratigráfica Xa de El Salt (Alcoi, este de Iberia) se han llevado a cabo estudios arqueoestratigráficos de alta resolución temporal.…
