A practical MRI-based reconstruction method for a new endocavitary and interstitial gynaecological template
2015
Purpose: There are perineal templates for interstitial implants such as MUPIT and Syed applicators. Their limitations are the intracavitary component deficit and the necessity to use computed tomography (CT) for treatment planning since both applicators are non-magnetic resonance imaging (MRI) compatibles. To overcome these problems, a new template named Template Benidorm (TB) has been recently developed. Titanium needles are usually reconstructed based on their own artifacts, mainly in T1-weighted sequence, using the void on the tip as the needle tip position. Nevertheless, patient tissues surrounding the needles present heterogeneities that complicate the accurate identification of these …
Traumatic brain injury: integrated approaches to improve prevention, clinical care, and research
2017
Executive summary A concerted effort to tackle the global health problem posed by traumatic brain injury (TBI) is long overdue. TBI is a public health challenge of vast, but insufficiently recognised, proportions. Worldwide, more than 50 million people have a TBI each year, and it is estimated that about half the world’s population will have one or more TBIs over their lifetime. TBI is the leading cause of mortality in young adults and a major cause of death and disability across all ages in all countries, with a disproportionate burden of disability and death occurring in low-income and middle-income countries (LMICs). It has been estimated that TBI costs the global economy approximately $…
Graft Healing in ACL Reconstruction: Can We Enhance It in Clinical Practice?
2012
The ACL-Deficient Knee: A Problem Solving Approach, focuses on problem analysis and problem solving, as well as analyzing the possibility of prevention. In each chapter, the biomechanics, anatomy, etc. that are relevant to the topic are reviewed. There are chapters where highly specialized surgical techniques are presented (v. gr. double bundle reconstruction or meniscal transplant), as well as developing areas such as ACL tears in children, where we are finding a growing number of injuries due to the increase of sports at early ages Surgical reconstruction of the anterior cruciate ligament (ACL) using tendon grafts is the current standard to treat the functionally ACL-deficient knee. The s…
Horizontal and Vertical Reconstruction of the Severely Resorbed Maxillary Jaw Using Subantral Augmentation and a Novel Tenting Technique with Bone fr…
2013
Aim The aim of this study was to evaluate the effect of using the lateral wall bone in sinus lifting two-dimensional reconstruction on bone augmentation.Patients and Methods Ten patients affected by class V or VI maxillary atrophy with less than 3 mm of residual horizontal ridge were selected. Using a piezo-ultrasonic surgery tip bony lateral wall was cut. To expose native bone to the bone graft, multiple perforations, made through the cortical plate of the recipient site with a round bur. Once the bony buccal wall was adjusted it was fixed away from the ridge with two 1.5 x 13 mm bone fixation screws. Deficiencies created between the bony buccal wall and the ridge was filled with a mineral…
A Semi-automatic Multi-seed Region-Growing Approach for Uterine Fibroids Segmentation in MRgFUS Treatment
2013
Fibroids are benign tumors growing in the uterus. Most of fibroids do not require treatment unless they are causing symptoms. Traditional surgery treatments, like myomectomy and hysterectomy, are very invasive therapeutic approaches which not always preserves reproductive potential of the woman. MRgFUS, performed with Insightec ExAblate 2100 equipment, is a new and noninvasive technique for uterine fibroids treatment, not requiring hospitalization and recovery time for patients. An initial assessment of MRgFUS treatment is made by computing the ablated volume of uterine fibroid. In this paper a semi-automatic approach, based on region-growing segmentation technique, is proposed. The impleme…
Construct validity and reliability of Finnish version of Örebro Musculoskeletal Pain Screening Questionnaire
2016
Abstract Introduction Chronic pain causes suffering for affected individuals and incurs costs to society through work disability. Interventions based on early screening of psychological risk factors for chronic pain using screening tools such as the Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ) have been found to reduce work absenteeism and health care visits and increase perceived health. The aim of the current study was to translate the ÖMPSQ into Finnish and test its validity and reliability in a patient sample. Methods The ÖMPSQ was forward–backward translated and cross-culturally adapted, and applied to our study population (n = 69), the members of which had been referred…
Reflecting on Female Beauty: Cosmetic Surgery and (Dis)Empowerment
2018
This project aims to unwrap some of the complexities related to female beauty and the body. It reflects on the second wave radical feminist view that beautifying the female body serves to attract male approval via the male gaze, both of which are deeply entrenched in patriarchal power. This perspective positions cosmetic surgery as a disempowering act for women. In riposte, we turn to third wave liberal feminist ideas to engage with the narratives of ten participants who tell of their personal experiences of, and motivations for, undergoing a cosmetic intervention. We undertake an in-depth exploration of these lifeworld experiences and the interplay of subjectivity and intersubjectivity in …
Similar biomechanical properties of four tripled tendon graft models for ACL reconstruction
2021
Abstract Purpose The present study tested and compared the biomechanical properties of four different triplicate graft tendon techniques. Methods 32 tripled tendons from the common extensor muscle of bovine fingers were tested on a material testing machine, passing the end loop over a metal rod of a clevis connected to the load cell on the upper side, and fixing the lower end to a clamp. The samples were divided into four groups: (A) tripled with a free end sutured only to one of the two fixed bundles (B) tripled with a free end positioned between the two fixed strands and sutured to both (C) tripled with an S-shape and all the three strands sutured together at the upper and lower extremiti…
Facial transplantation: A concise update
2012
Objectives: Update on clinical results obtained by the first worldwide facial transplantation teams as well as review of the literature concerning the main surgical, immunological, ethical, and follow-up aspects described on facial transplanted patients. Study design: MEDLINE search of articles published on “face transplantation” until March 2012. Results: Eighteen clinical cases were studied. The mean patient age was 37.5 years, with a higher prevalence of men. Main surgical indication was gunshot injuries (6 patients). All patients had previously undergone multiple conventional surgical reconstructive procedures which had failed. Altogether 8 transplant teams belonging to 4 countries part…
Evaluation of the methodological quality of articles on autologous breast reconstruction
2018
Abstract Background Breast cancer remains the most common cancer among women worldwide. Autologous breast reconstruction may contribute toward restoring body image and improving quality of life after mastectomy. This systematic literature review describes differences in the quality and type of studies investigating autologous breast reconstruction techniques over time. Methods MEDLINE was searched for articles related to the surgical techniques, namely, TRAM, LADO, DIEP, and SGAP/IGAP, for the periods 1970 to 2007 and 2008 to 2010. The quality and type of studies were compared across the two time periods. Full-texts were evaluated according to prespecified quality criteria. Results The MEDL…
