A Morel-Lavallee lesion (MLL) is a relatively rare condition that is caused by a traumatic shearing force. This force leads to a closed degloving injury of the subcutaneous tissue and fascia that creates a potential space that can fill with lymph, blood, and necrotic fat. The MLLs are traditionally seen after high impact trauma and typically located at the greater trochanter and pelvis, although recent reports have found them to be located at the knee, thigh, and lower leg. The MLLs typically present as swelling at the site of injury, which can be difficult to differentiate from several other diagnoses...

The use of computer simulated digital x-radiographs for optimisation purposes has become widespread in recent years. To make these optimisation investigations effective, it is vital simulated radiographs contain accurate anatomical and system noise. Computer algorithms that simulate radiographs based solely on the incident detector x-ray intensity ('dose') have been reported extensively in the literature. However, while it has been established for digital mammography that x-ray beam quality is an important factor when modelling noise in simulated images there are no such studies for diagnostic imaging of the chest, abdomen and pelvis...

Metastases to bone are the most frequent cause of destructive lesions to the skeleton in adults . The tumours that are most likely to metastasize to bone are prostate (32%), breast (22%), kidney (16%), lung and thyroid. The typical distribution of metastatic lesions are to the spine, ribs, pelvis, and proximal limb girdles. The humerus is the second most common site for long bone metastases, behind only the femur in its frequency of involvement . It represents the 20% of all bony metastases. We present a clinical case of an 86 yo woman with a previous diagnosis of myofibroblastic sarcoma of the maxillaris who suffers a pathological fracture of the humeral shaft secondary to metastasis and was misdiagnosed and treated for a typical humeral fracture using and intramedullary pinning (Hackethal technique), producing the progression of the disease within the humeral shaft...

There are very few epidemiological studies on Japanese patients with deep vein thrombosis (DVT). In particular, mortality rate differences in Japanese DVT patients with and without malignancy have rarely been evaluated. To elucidate these differences, we enrolled 211 patients who had been diagnosed with de-novo acute DVT of the pelvis or lower extremities between January 2012 and December 2015. The clinical characteristics, treatment information, and follow-up data were retrospectively assessed. We compared these variables in patients with (n = 120) and without (n = 91) concomitant malignancies...

PURPOSE: The use of large-field external beam reirradiation (re-RT) after pelvic radiation therapy (RT) for genitourinary (GU) cancers has not been reported. We report the results of such treatment in patients with either symptomatic GU second malignant neoplasms or locally recurrent pelvic tumors after initial RT for whom surgery or further systemic therapy was not an option. METHODS AND MATERIALS: The records of 28 consecutive patients with advanced, bulky GU malignancies treated with high-dose, large-field re-RT with palliative intent between 2008 and 2014 were retrospectively reviewed...

BACKGROUND: The American Congress of Obstetricians and Gynecologists recommends that "the surgeon and patient discuss the potential benefits of the removal of the fallopian tubes during a hysterectomy in women at population risk of ovarian cancer who are not having an oophorectomy," resulting in an increasing rate of salpingectomy at the time of hysterectomy. Rates of salpingectomy are highest for laparoscopic and lowest for vaginal hysterectomy. OBJECTIVES: The primary objective of this study was to determine the feasibility of bilateral salpingectomy at the time of vaginal hysterectomy...

Fatigue, developed over the course of a run, may cause changes in running kinematics. Training status may influence the effect of fatigue on running kinematics, since well trained, competitive runners are used to running until exhaustion, whereas novice runners are not. This study aimed to determine changes in running kinematics during an exhaustive run in both novice (NOVICE) and competitive (COMP) long-distance runners. About 15 NOVICE and 15 COMP runners performed a treadmill run, until voluntary exhaustion at 3,200 m time trial pace...

Leiomyosarcoma is a rare condition so there are relatively few and small case series and no prospective studies to provide clear guidelines regarding management. We report on a case that presents some particularities that further underline diagnostic and treatment difficulties posed by the affliction of such a rare tumor. This is the case of a 43-year-old woman who had a large tumor arising from the uterus, with a spectacular growth rate over a short period. The patient, with congenital spastic tetraparesis and hydrocephalus, came for belly enlargement with rapid increase in size over the previous two months...

Fecal incontinence (FI) is a disabling problem affecting women. Conservative treatment includes dietary modification, antimotility agents, and pelvic floor physical therapy. If conservative medical management is unsuccessful, surgical intervention may be required. Surgical options include rectal sphincteroplasty, bulking agent injection, radiofrequency anal sphincter remodeling procedure and sacral nerve stimulation (SNS) therapy. Recently, a new therapy for FI, the FENIX Continence Restoration System has become available...

Total mesorectal excision (TME) is a mile-stone procedure in the history of rectal cancer surgery, but the exposure of surgical field of distal rectum is usually poor in patients with male, obese and narrow pelvis, which may lead to tumor residue and relative complications. Recently, a new technique called transanal TME (taTME) is considered to solve the above problems, but most medical centers are still in the learning curve of this procedure. Therefore, anatomical planes and landmarks of taTME for rectal cancer and prophylaxis of intraoperative complications are induced in this paper, which includes posterior plane: angle of anus and distal mesorectum and bleeding of mesorectum; rectosacral fascia and presacral bleeding; lateral and posterior-lateral plane: posterior branches of pelvic plexus and damage of anal function; anterior plane: vessel branches of neurovascular bundle and bleeding...

The role of imaging after surgery is pivotal to drive clinical management of early and/or late onset complications. Most frequently used imaging technique after pelvic surgery is Ultrasound (US), Magnetic Resonance Imaging (MRI) and Computed Tomography (CT). While Ultrasound is a standard procedure, using grey scale and/or colour Doppler evaluation, MRI and CT scan protocols should be derived on the basis of the specific indication of the exam. Correct evaluation of female pelvis after gynaecologic surgery, having in mind the most frequent complications, is based on the correct use of the instruments and on the experience of the examiner, who should be aware of the history of the patient, type of surgery and clinical symptoms for which the exam is required; the clinician should be aware of the possibilities and limits of the different techniques, in order to choose the most appropriate imaging modality and promptly make a correct diagnosis...
