PURPOSE: In this study, we developed a 3D-printed deformable pelvis phantom for evaluating spatial DIR accuracy. We then evaluated the spatial DIR accuracies of various DIR settings for cervical cancer. METHODS: A deformable female pelvis phantom was created based on patient CT data using 3D printing. To create the deformable uterus phantom, we first 3D printed both a model of uterus and a model of the internal cavities of the vagina and uterus. We then made a mold using the 3D printed uterus phantom...

OBJECTIVE: The Manchester repair, developed in the UK by Donald, described in 1908, and later modified by Fothergill, is a well-studied and proven surgical treatment for uterovaginal prolapse when uterine preservation is desired. This operation is currently not widely performed in parts of the world (USA) but is becoming increasing popular in Europe. The objective of this video is to demonstrate our surgical technique and recommendations for successful completion of the procedure. METHODS: This patient is a 39-year-old woman with two previous vaginal deliveries who presented with a 1-year history of vaginal protrusion...

INTRODUCTION: Inguinal lymph nodes are the frequent sites of metastasis for malignant lymphoma, squamous cell carcinoma of anal canal, vulva and penis, malignant melanoma and squamous cell carcinoma of skin over lower extremities or trunk. Anatomically, endometrial carcinoma is less likely to spread to the superficial or deep inguinal lymph nodes, thus metastatic involvement of these lymph nodes can easily be overlooked. CASE PRESENTATION: Here-in we report a case of a 65-year old Saudi morbid obese female, who presented with left inguinal lymphadenopathy as initial delayed site of metastasis almost 19 months after the initial treatment for FIGO IA endometrial carcinoma...

BACKGROUND: Sodium fluoride (NaF) positron emission tomography combined with computer tomography (PET/CT) has shown to be more sensitive than the whole-body bone scan in the detection of skeletal uptake due to metastases in prostate cancer. We aimed to calculate a 3D index for NaF PET/CT and investigate its correlation to the bone scan index (BSI) and overall survival (OS) in a group of patients with prostate cancer. METHODS: NaF PET/CT and bone scans were studied in 48 patients with prostate cancer...

BACKGROUND: Athletic groin pain (AGP) is prevalent in sports involving repeated accelerations, decelerations, kicking and change-of-direction movements. Clinical and radiological examinations lack the ability to assess pathomechanics of AGP, but three-dimensional biomechanical movement analysis may be an important innovation. AIM: The primary aim was to describe and analyse movements used by patients with AGP during a maximum effort change-of-direction task. The secondary aim was to determine if specific anatomical diagnoses were related to a distinct movement strategy...

Augmentation cystoplasty is a procedure to increase the anatomical as well as functional capacity of the urinary bladder using a segment of bowel or ureter. Upto half of these patients develop complications but most of them are minor and managed easily. Urolithiasis, especially bladder calculi are seen in upto half of the cases and are removed endoscopically or by open approach. Hysterectomy is an uncommon procedure in patients with augmentation cystoplasty and is complicated by the altered anatomy of the pelvis...

Determining three-dimensional (3D) acetabular orientation is important for several orthopaedic scenarios, but the complex geometries of both pelvis and acetabulum make measurements of orientation unreliable. Acetabular orientation may also differ between the sexes or racial groups. We aimed to (1) establish and evaluate a novel method for measuring 3D acetabular orientation, (2) apply this new method to a large population of Chinese subjects, and (3) report relevant characteristics of native acetabular orientation in this population...

INTRODUCTION: Surgical management for lumbar stenosis is generally safe and provides significant improvements in pain, disability, and function. Successful lumbar decompression hinges on removing an appropriate amount of lamina and other compressive pathology in the lateral recess. Too little bony decompression can result in persistent pain and disability, while over resection of the pars and/or facets may jeopardize spinal stability. CASE REPORT: In this unique report, we present for the first time an acute iatrogenic grade 4 L5-S1 spondylolisthesis distal to a L3-5 laminectomy and circumferential instrumented fusion due to bilateral iatrogenic L5 pars fractures and its management and clinical outcomes after revision operation...

Costello syndrome is caused by heterozygous de novo missense mutations in the protooncogene HRAS with tumor predisposition, especially rhabdomyosarcoma. We here report two pediatric patients with Costello syndrome and umbilical ligament rhabdomyosarcoma. A review of the literature published in English in MEDLINE from January 1971 to June 2016 using the search terms "Costello syndrome" and "rhabdomyosarcoma" was performed, including two new cases that we describe. Twenty-six patients with Costello syndrome and rhabdomyosarcoma were recorded with mean age of diagnosis of 2 years and 8 months...

Behavioral observation techniques which relate action to personality have long been neglected (Furr and Funder in Handbook of research methods in personality psychology, The Guilford Press, New York, 2007) and, when employed, often use human judges to code behavior. In the current study we used an alternative to human coding (biomechanical research techniques) to investigate how personality traits are manifest in gait. We used motion capture technology to record 29 participants walking on a treadmill at their natural speed...

BACKGROUND: Supplementary iliac screws have the highest potential to protect S1-pedicle-screws from loosening in long fusion constructs. However, this technique bridges the iliosacral joint with potential disadvantages for the patient. This study aimed to evaluate if two different established fixation techniques can be used in addition to pedicle screws as alternative to iliac screws, and if these two techniques can provide similar stability when S1-pedicle-screws are loosened. METHODS: Flexibility testing with pure moments of 7...

Cranial crests show considerable variation within the Pterosauria, a group of flying reptiles that developed powered flight. This includes the Wukongopteridae, a clade of non-pterodactyloids, where the presence or absence of such head structures, allied with variation in the pelvic canal, have been regarded as evidence for sexual dimorphism. Here we discuss the cranial crest variation within wukongopterids and briefly report on a new specimen (IVPP V 17957). We also show that there is no significant variation in the anatomy of the pelvis of crested and crestless specimens...

BACKGROUND: Radical nephroureterectomy (RNU) with bladder cuff excision (BCE) is the surgical principle adopted for the treatment of upper tract urothelial cancers (UTUCs). However, not all RNUs are performed with BCE. We quantified the prognostic impact of RNU with BCE on cancer-specific survival (CSS) in a large patient population. METHODS: In total, 505 patients with UTUC were enrolled from four different institutions. The clinicopathological parameters of patients who underwent RNU with and without BCE were compared...

BACKGROUND: Cancer incidence rates and trends for cases diagnosed through 2014 using data reported to the Surveillance, Epidemiology, and End Results (SEER) program in February 2016 and a validation of rates and trends for cases diagnosed through 2013 and submitted in February 2015 using the November 2015 submission are reported. New cancer sites include the pancreas, kidney and renal pelvis, corpus and uterus, and childhood cancer sites for ages birth to 19 years inclusive. METHODS: A new reporting delay model is presented for these estimates for more consistent results with the model used for the usual November SEER submissions, adjusting for the large case undercount in the February submission...
