Surgical repair of acute Achilles tendon rupture with an end-to-end tendon suture and tendon flap.

2015

Abstract Background Achilles tendon ruptures are becoming more common. Complications after open or minimally invasive surgery are: recurrent rupture (2–8%), wound breakdown, deep infections, granuloma, and fistulas. The authors expose their experience with a personal technique. Materials In 8 patients with acute rupture of Achilles tendon the surgery was performed at least 25 days after trauma. Clinical exam and MR demonstrated in all case a total lesion of tendon. After a posterolateral skin incision the tendon stumps were debrided and suture in end-to-end fashion. A tendon flap was harvested from the proximal part of the tendon, in order to protect and reinforce the suture itself. A plast…

Reconstruction of full thickness scalp defects after tumour excision in elderly patients: our experience with Integra dermal regeneration template.

2010

Summary Background Scalp reconstruction after wide tumor excision is particularly challenging. Free tissue transfers, local flaps, or skin grafts can be used but present some disadvantages especially with old patients with local advanced cancers, systemic diseases and in patients with a prior history of recurring scalp skin cancers in which the risk of burying a recurring tumor with a flap is likely. The Authors expose their early experience with Integra ® dermal regeneration template for scalp reconstruction after scalp tumor excision. Methods Eight patients with primary or secondary scalp tumor underwent a first surgical procedure under local anaesthesia for tumor removal and Integra ® po…

Surgical treatment of pharyngostomes in irradiated patients. Our experience with musculocutaneous pectoralis major flap and hyperbaric oxygen therapy

On the moving loads problem in discontinuous homogeneous beams and layered beams with interlayer slip

This manuscript contains the main part of my research performed in this last triennium at the Department of Civil, Environmental, Aerospace and Materials Engineering, University of Palermo, and at the Department of Basic Sciences in Engineering Sciences (Unit of Applied Mechanics), University of Innsbruck, Austria. The research adheres to a common procedure of solving a scientistic problem. That is, introduction to the problem, selection of the mathematical and physical tools to model the problem, proposed solution, and numerical validation. The thesis proposes a novel modal superposition approach to the moving loads problem on discontinuous homogeneous beam and layered beam with interlayer…

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

2021

Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in su…

Reconstruction of the face with skin-grafted muscle flaps: Optimizing the aesthetic outcome

2011

BACKGROUND: Reconstruction of large defects in the temporal region can be performed with skin grafts or pedicled or free flaps. Results are often not optimal because of the patch of a skin graft, lack of availability of local flaps, and distant skin from free flaps. A technique for reconstruction of these defects with local tissue is presented in this article that uses superficial musculoaponeurotic system (SMAS) plication to allow wide advancement of a cervicofacial flap. METHODS: Once the defect is outlined, a face-lift-like skin incision is used to raise the flap. The SMAS is plicated with two purse-string sutures that relieve tension on the flap and allow maximal advancement. Thirteen f…

Moving multi-loads problem in layered cracked beams with interlayer slip

2017

This contribution concerns the vibration response of layered cracked uniform beams with interlayer slip under moving multiple loads. Considering a linear constitutive relation between the horizontal slip and the interlaminar shear force, the Euler-Bernoulli hypothesis is assumed to hold for each layer separately. Modeling cracks as internal elastic rotational joints, related discontinuities of the response variables are treated by the theory of generalized functions. In this manner, exact eigenfunctions are derived from a characteristic equation built as determinant of 6x6 matrix, for any number of cracks. Building pertinent orthogonality conditions for the deflection eigenfunctions, the re…

Uncommon case of symmetrical fibrous hyperplasia of the hard palate.

2010

The fibrous hyperplasia of the palate (fibroma) is a benign tumor which has its origin in the soft tissue and whose frequency is estimated to be 1.2% on adult subjects. Rarely the size exceeds the cm, but in these cases a complaint of increasing difficulty of mastication and swallowing appears. We describe the case of a young white woman affected with two peculiar symmetric lesions of the secondary hard palate, that could be the consequence of an abnormal answer to a chronic inflammatory stimulation.
