The Relationship Between Aortic Root Size and Hypertension: An Unsolved Conundrum
2017
Thoracic aortic aneurysms rupture and dissection are among the most devastating vascular diseases, being characterized by elevated mortality, despite improvements in diagnostic imaging and surgical techniques. An increased aortic root diameter (ARD) represents the main risk factor for thoracic aortic dissection and rupture and for aortic valve regurgitation. Even though arterial hypertension is commonly regarded as a predisposing condition for the development of thoracic aorta aneurysms, the role of blood pressure (BP) as determinant of aortic root enlargement is still controversial. The use of different methods for indexation of ARD may have in part contributed to the heterogeneous finding…
Bipolar Quantum Molecular Resonance versus Blunt Dissection tonsillectomy
2015
Bipolar Quantum Molecular Resonance versus Blunt Dissection tonsillectomy. Objectives: This study compared a quantum molecular resonance tonsillectomy (QMRT) to a standard blunt dissection tonsillectomy (BDT) for effectiveness and safety. Methodology: From January 2011 to September 2012, we recruited 80 children (ages 3 to 16 y) with paediatric obstructive sleep apnoea syndrome and/or recurrent tonsillitis. Patients were randomly assigned to receive QMRT (N = 40) or BDT (N = 40). The operating time and blood loss during surgery were evaluated. During the first postoperative week, the patients' parents completed a questionnaire to evaluate bleeding, ear and neck pain, nausea, vomiting, inter…
Intraoral onlay block bone grafts versus cortical tenting technique on alveolar ridge augmentations: a systematic review
2021
To review systematically the bone gain and superficial resorption rate of the onlay block bone grafts versus the cortical tenting technique, as well as secondarily study the postoperative complications, implant survival and success rates, and peri-implant marginal bone loss. Following the recommended methods for systematic reviews and meta-analyses (PRISMA), an electronic search was performed in the PubMed (MEDLINE), EMBASE and the Cochrane Library of the Cochrane Collaboration (CENTRAL) databases to identify all relevant articles published up to March 2021 on onlay block bone grafts and cortical tenting technique. Eighteen papers complied with the inclusion criteria. In onlay grafts, the v…
Revascularisation of a Giant Coronary Artery Aneurysm in Suspected Incomplete Kawasaki-Disease
2006
Kawasaki disease leads to typical vascular complications in up to 20 % of untreated cases. We describe a 47-year-old patient with coronary vessel disease, involving the right coronary artery with a huge aneurysmatic dilatation, suspicious for an incomplete form of Kawasaki disease. We found little information about the surgical treatment and postoperative course of this disease in adults. Typically, these infrequent patients present with acute myocardial infarction and require interdisciplinary decision-making.
Predictive factors for lymph node involvement in sporadic medullary thyroid microcarcinoma: A systematic review
2022
Objective: The aim of the study was to determine the impact of laboratory and imaging tests in predicting central and lateral neck lymph node/LN involvement and in decision making for surgical extent. Materials and Methods: A PubMed, Web of Science and Scopus search was performed according to PRISMA criteria. The relationship between nodule size, diagnostic biomarkers and imaging with LN involvement were evaluated. Results: The available data analysis did not yield clear indications of the relationship between each of these topics and the presence, number, and location of LN involved. There was no conclusive data for the selective indication of central neck dissection in the preoperative di…
Does Ligasure(TM) Reduce Fluid Drainage in Axillary Dissection? A Randomised Prospective Clinical Trial
2007
Background: Axillary lymph node dissection (ALND) is an integral part of breast cancer treatment. It is required in about 40–50% of patients. The placement of a drain in the axilla after an operation is current surgical practice. Short surgical stay programmes increase operating efficiency and reduce medical care costs, without compromising quality of care. LigaSureTM is a new haemostatic device that uses bipolar energy to seal vessels. The aim of this study is to determine whether axillary dissection with LigaSureTM reduces the time of wound drainage, the duration of surgical intervention and the volume of drainage after treatment. Patients and methods: This study is a prospective randomiz…
Conservative treatment of initial breast cancer
1988
The results of conservative surgical techniques (quadrantectomy or tumorectomy), axillary dissection and radiotherapy in 58 patients with initial breast cancer (Tt No, Mo) treated between June 1979 and December 1986 are reported. The disease-free survival rates after 5 and 8 years were 84% and 76% respectively. Four cases developed local recurrences (6.9%); 2 cases developed distant metastases involving lung and bone, and 1 case developed bone metastases without local recurrence. Two patients with local recurrence underwent radical life-saving mastectomy and are now free from disease.
Current Role of Intraoperative Frozen Section Examination of Sentinel Lymph Node in Early Breast Cancer.
2020
Background/Aim: The aim of this study was to evaluate the current role of frozen section in identifying patients who could benefit from an immediate axillary lymph node dissection (ALND), following the criteria of the ASOCOG Z0011 and IBCSG 23-10 trials. Patients and Methods: A retrospective review was performed involving 2,079 patients with early breast cancer who underwent conservative surgery or total mastectomy with sentinel lymph node biopsy. Results: Sensitivity and diagnostic accuracy were 63.8% and 90.3%, respectively. Sensitivity was significantly higher (p<0.001) in finding macrometastases (81.8%) compared to micrometastases (11.9%). Frozen section was useful only in 7.7% of th…
Impact of sentinel node biopsy on long-term quality of life in breast cancer patients
2013
Background: The aim of this study was to assess long-term quality of life (QoL) over a period of 6 years in women with breast cancer (BC) who underwent sentinel lymph node biopsy (SLNB), axillary lymph node dissection (ALND), or SLNB followed by ALND. Methods: The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ)-C30 and the EORTC-QLQ-BR-23 questionnaires were used to assess QoL before surgery, just after surgery, 6, 12 and 72 months later. The longitudinal effect of surgical modalities on QoL was assessed with a mixed model analysis of variance for repeated measurements. Results: Five hundred and eighteen BC patients were initially include…
Sentinel lymph node biopsy in T1/T2 squamous cell carcinomas of the tongue: A prospective study
2014
Commonly used staging procedures often cannot predict the absence of cervical metastases (CM) in squamous cell carcinomas (SCCs) of the oral cavity. Due to the high incidence of occult CM in numerous N0 cases in the clinic, an elective neck dissection (ND) is performed. The sentinel lymph node biopsy (SNB) is a common concept in the modern surgical therapy of malignancies. The present study evaluates the applicability of this concept for T1/T2-SCC of the tongue. In a prospective clinical study, 10 consecutive patients with T1/T2-SCC of the tongue and cN0 necks, were enrolled. Following sentinel lymph node (SLN) scintigraphy, all patients underwent SNB with a γ-probe and a subsequent ND. SNB…
