Background: The aim of our work is to assess the potential role of texture analysis (TA), applied to computed tomography (CT) simulation scans, in relation to the development of insufficiency fractures (IFs) in patients undergoing radiation therapy (RT) for pelvic malignancies. Methods: We analyzed patients undergoing pelvic RT from Jan-2010 to Dec-2016, 31 of whom had developed IFs of the pelvis. We analyzed CT simulation scans using LifeX Software© , and in particular we selected three regions of interest (ROI): L5 body, the sacrum and both the femoral heads...

The growth in the use of magnetic resonance imaging (MRI) data for radiation therapy (RT) treatment planning has been facilitated by scanner hardware and software advances that have enabled RT patients to be imaged in treatment position while providing morphologic and functional assessment of tumor volumes and surrounding normal tissues. Despite these advances, manufacturers have been slow to develop radiofrequency (RF) coils that closely follow the contour of a RT patient undergoing MR imaging. Instead, relatively large form surface coil arrays have been adapted from diagnostic imaging...

PURPOSE: To evaluate the effectiveness of CT image-guided proton radiotherapy for prostate cancer by analyzing the positioning uncertainty and assessing daily dose change due to anatomical variations. MATERIALS AND METHODS: Patients with prostate cancer were treated by opposed lateral proton beams based on a passive scattering method using an in-room CT image-guided system. The system employs a single couch for both CT scanning and beam delivery. The patient was positioned by matching the boundary between the prostate and the rectum's anterior region identified in the CT images to the corresponding boundary in the simulator images after bone matching...

BACKGROUND: Canal wall down (CWD) mastoidectomy has many drawbacks including chronic otorrhea, granulations, dizziness on exposure to cold or hot water and tendency of debris accumulation in the mastoid cavity demanding periodic cleaning. Many of these problems can be solved by reconstruction of the posterior meatal wall (PMW). OBJECTIVES: To assess the results of PMW reconstruction after CWD mastoidectomy for cholesteatoma using bioactive glass (BAG) that is fabricated and built up intraoperatively...

Massive weight loss patients and aesthetic patients can present with significant gluteal contour abnormalities. Gluteal ptosis, skeletal deformities, severe platypgia, and a paucity of donor fat for autologous transfer are common problems. Excisional procedures are used to treat massive-weight-loss contour abnormalities. These procedures present an opportunity to address severe gluteal deformities using autologous tissue augmentation. With a working knowledge of the relevant anatomy, sound surgical technique, and meticulous postoperative care, autologous gluteal autoaugmentation with circumferential body lift/excisional buttock lift using the "Moustache" flap technique will enhance massive weight loss body contouring outcomes and improve patient satisfaction...

Postbariatric, cosmetic, and circumferential body lift patients seek to avoid a flattened buttock contour. Gluteal implants have been described with various rates of complications and difficulties. Lipografting moderately increases buttock volume; neither procedure directly addresses ptosis. The procedure described in this article addresses the volume deficit and ptosis. Most adipocutaneous flaps originate within the superior gluteal region and maintain volume in the top half of the buttocks, lacking the ability to reach the midportion of the buttocks...

The mandibular fracture is one of the most commonly fractures of the facial bones. In high-energy traumas, a comminuted mandible fracture may occur. The closed reduction with external fixator is an interesting alternative for these types of fractures. The aim of this article is to report the case of a patient with comminuted fracture in the right mandibular body, whose surgical treatment was the noninvasive reduction of fracture and stabilization using a Colles' wrist external fixator. After 1 year of follow-up, the patient is without complaints, with satisfactory dental occlusion, adequate contour, and mandibular alignment...

Investigations suggest the benefits of low-level laser therapy (LLLT) to improve noninvasive body contouring treatments, inflammation, insulin resistance and to reduce body fat. However, the mechanism for such potential effects in association with exercise training (ET) and possible implications in browning adiposity processes remains unclear. Forty-nine obese women were involved, aged between 20 and 40 years with a body mass index (BMI) of 30-40 kg/m2 . The volunteers were divided into Phototherapy (808 nm) and SHAM groups...

A 35-year-old male patient was presented with pain on his right upper eyelid. A piece of wood injured his orbital and supraorbital regions while working at a furniture factory 10 days prior to our hospital admission. It was learned that the patient was discharged following the primary would closure procedure. Subsequent to the craniofacial computed tomography, primary wound closure was performed in the emergency room of previous hospital. In our clinic, a skin suturing on the nasal side of the right eyebrow was inspected and a foreign body (FB) was palpated on the superonasal contiguity of the patients' right globe...

BACKGROUND: Abdominoplasty is the most frequently performed surgical procedure for body contour; in our experience, we have observed some patients with prominent bulging that is difficult to treat and that presents results that are unsatisfactory or have recurrences to conventional treatments. This leads us to carry out an analysis of the elements responsible for the containment and abdominal format. We determined that it may be due to an inability of an important sagging aponeurotic muscle of primary origin to support the abdomen and could be caused by predisposing factors...

Radiation dermatitis during radiotherapy is correlated with skin dose and is a common clinical problem for head and neck and thoracic cancer patients. Therefore, accurate prediction of skin dose during treatment planning is clinically important. The objective of this study is to evaluate the accuracy of skin dose calculated by a commercial treatment planning system (TPS). We evaluated the accuracy of skin dose calculations by the anisotropic analytical algorithm (AAA) implemented in Varian Eclipse (V.11) system...

Stem cell-based therapies have been widely used for their abilities to repair and regenerate different types of tissues and organs in cosmetic and plastic surgeries. It involves the clinical application of different types of stem cells. Different stem cells have been reported to be applicable in different areas of cosmetic surgeries like face lipoatrophy, skin rejuvenation, breast enhancement and body contouring. However adipose-derived stem cells (ADSC) remains the most widely used by cosmetic surgeons as they have the potential and capability to differentiate into mesenchymal, ectodermal and endodermal lineages and are easily accessible to harvest...

BACKGROUND AND OBJECTIVES: Massive weight loss (MWL) can result in variable contour deformities of the breasts. The Pittsburgh Rating Scale (PRS) was designed to describe the multitude of deformities after MWL and recommends operations to consider for surgical improvement. We present the first comprehensive description of breast deformities in a large sample of MWL patients, examine factors affecting the severity of deformities, and report the correlation between PRS score and surgical decision making...

The free vascularized fibular graft is nowadays the preferred technique for pediatric mandibular reconstruction. Despite the versatility and proven efficacy for restoring the facial appearance and maxillomandibular function, those mandibular reconstructions with free vascularized fibula associate difficulties for a simultaneous restoration of the alveolar height and facial contour, which are derived from the height discrepancy between the fibula and the native mandible. In addition, the donor-site growth and morbidity are of special concern in the pediatric patient...

We present a new reconstructive system encompassing prostheses and fat grafting as integrated tools to improve the final reconstructive outcome. Fat grafting in our view is a pre-operatively planned part of the reconstruction. The final volume we achieve will be made up of fat and implants in a variable percentage according to patient's body contour and breast morphology. We used the "Hybrid Breast Recontruction" technique in more than 350 reconstructions, both immediate and delayed, two-stage and DTI, without experiencing higher loco-regional recurrence and complication rates when compared with conventional two-stage reconstructions, obtaining excellent aesthetic results and high patients' satisfaction levels...

Although tissue engineering has been attracted greatly for healing of critical-sized bone defects, great efforts for improvement are still being made in scaffold design. In particular, bone regeneration would be enhanced if a scaffold precisely matches the contour of bone defects, especially if it could be implanted into the human body conveniently and safely. In this study, polyurethane/hydroxyapatite-based shape memory polymer (SMP) foam was fabricated as a scaffold substrate to facilitate bone regeneration...

PURPOSE: Proton dose coverage is sensitive to proton beam range. The current practice of CT number-based registration for patient positioning focuses on matching the target and is not sufficient for proton therapy because the proton range depends on the medium traversed by the beam. Patient body deformations and anatomical changes result in range deviation in the target. We propose proton range-based registration to minimize the range deviation. METHODS: The range was calculated from cone beam-computed tomography (CBCT) of the patient on couch, and the range deviation was the difference of the calculated range from that on the initial (day 1) CBCT...
