Role of prophylactic central neck dissection in cN0-papillary thyroid carcinoma: Results from a high-prevalence area
2016
BACKGROUND: Prophylactic, compartment-oriented central neck dissection (CND) for cN0 papillary thyroid carcinoma (PTC) is not widely practiced. We examined our results with this surgical approach. METHODS: A cohort of 158 patients operated on for the classical variant of PTC at a follow-up of 1-22 years (mean: 6.6) were enrolled. The patients with a preoperative diagnosis of cN0 PTC (group A, 59 patients) underwent total thyroidectomy (TT) + CND. In the patients with incidental postoperative diagnosis of malignancy (group B, 99 patients) a TT alone was performed. RESULTS: Ninety-six T1, 36 T2, 26 T3/T4 PTC patients were enrolled. The overall biochemical/scintigraphic recurrence rate (15 pat…
A BRIEF ANATOMO-SURGICAL DISSECTION GUIDE TO HUMAN NECK: RESULTS OF THE COLLABORATION BETWEEN THE UNIVERSITY OF PALERMO AND THE UNIVERSITY OF MALTA
2018
The aim of this article is to show methods for dissection of the neck. In the summer of 2017 a group of students of the University of Palermo that have already passed the exam of Human Anatomy took a 4 weeks dissection course at the University of Malta. The students were provided with a dissection kit, video recording equipment and cameras for taking pictures. They dissected the skin, the subcutaneous tissue, the muscular bundles, the muscles, the vascular and nervous bundles, the nerves, the larynx, the trachea and the esophagus. 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 neck di…
A BRIEF DISSECTION'S GUIDE TO NORMAL MEDIASTINAL ANATOMY
2019
The purpose of this article is to show the mediastinal dissection method used during the stage performed by a group of students from the Univrersity of palermo that, during the sumer of 2017, had the opportunity to spend a period of 4 weeks at the Department of Anatomy of The University of malta. The students were guided to practice dissection of some corpes to study various mediastinal organs. This experience permitted to the students to verify practically what they lernt in the books, and reperesented a unique opportunity for them to perform practice with cadavers, that is actually very difficult to do in italian universities.
ANATOMICAL DISSECTION AND ANALYSIS OF THE STRUCTURES OF THE UPPER LIMB
2017
In 2015, a whole body dissection course was proposed by the University of Palermo, Palermo, Italy, thanks to the cooperation with the University of Malta, Msida, Malta. The purpose of this study was to show the the difference between the studyof anatomy on books and on corpses. The article focuses its attention on the dissection method of the upper limb. The astudy was performed on two corpses, a male and a female, by using a basic surgeon kit. Blunt dissection method was used for fasciae, innards and to isolate vascular-nervous structures from the fat; we used scalped for cutis, sub cutis, muscles, fasciae, veins, arteries and nerves of the upper limb from the shoulder to the hand. The upp…
The sentinel node biopsy is not contraindicated in multifocal breast carcinoma
2011
Aim. Following the availability of the results ofvalidation studies, the sentinel lymph node biopsy(SLNB) has replaced routine axillary dissection(AD) as the new standard of care in early unifocal breast cancers.Multifocal (MF) and multicentric (MC) tumours have been considered as a contraindication for this technique due to the possible incidence of a higher false-negative rate. In this retrospective study we try to demonstrate the usefulness of SLNB in MF/MC breast carcinoma. Patients and Methods. Eight hundreds and fiftyeightpatients with breast carcinoma underwent a conservative surgery and sentinel node excision. Ninety-four out of 858 patients had histological diagnosis of multifocal …
Neck node dissection in thyroid cancer. A review.
2010
INTRODUCTION: thyroid cancer recurs most commonly in one or more cervical lymph nodes. Surgical treatment for differentiated or medullary thyroid carcinoma consists of total thyroidectomy (TT). The aim is to elucidate the potential benefits and drawbacks of neck dissection TT related. MATERIALS AND METHODS: differences between therapeutic and prophylactic neck dissection were analysed to prevent post-operative morbidity, neck recurrences and improve survival. DISCUSSION: there is considerable controversy regarding the treatment of patients with cervical node metastases specially in differentiated thyroid cancer. Considering that a neck dissection might help to reduce local recurrence, espec…
Two cases of intra-pericardic dissection in Turner's syndrome women
2011
Turner's syndrome is a genetic partial or complete monosomy of sexual chromosome X; therefore women affected by Turner's syndrome have 45 (XO) caryotype. In 15% of the cases Trner's syndrome is associated with cardiac congenital malformations, the most frequent anomalies are the aortic coartaction and the defect of interventricular septum. The authors introduce two cases of deceased women affected by Turner's syndrome caused by intrapericardic dissection of the ascending aorta.
Genetic contribution in sporadic thoracic aortic aneurysm? Emerging evidence of genetic variants related to TLR-4-mediated signaling pathway as risk …
2015
Abstract Sporadic thoracic aortic aneurysms (TAA) and dissections are one of the major causes of morbidity and mortality worldwide, especially in those older than 65 years. The presentation of TAA is varied and often silent. Thus, sporadic TAA detection is often fortuitous, with identification occurring during a routine physical examination or during an unrelated medical evaluation. Once suspected, confirmation by imaging clinical approaches is needed to allow the choose of the unique treatments for TAA, namely the surgery procedures, including elective surgery or endovascular repair before the onset of catastrophic and fatal complications, such as dissection or rupture. At present, there a…
Infarto cerebral isquémico por disección de arteria carótida interna
2003
La disección de la arteria carótida interna es una causa importante de ictus isquémico en niños y pacientes jóvenes. En la patogenia se han implicado traumatismos y/o un posible defecto estructural de la pared arterial. Las manifestaciones clínicas típicas incluyen cefalea o dolor de cuello y síndrome de Horner en el lado de la disección, con la aparición después de síntomas isquémicos cerebrales. La ecografía, el Doppler transcraneal, la resonancia magnética (RM), la angiorresonancia y la angiografía proporcionan el diagnóstico. Las opciones de tratamiento comprenden anticoagulantes, antiagregantes plaquetarios y cirugía. Presentamos un adolescente de 14 años con un ictus isquémico secunda…
