Comparative Study
OBJECTIVE
The aim: A comparative analysis of the efficiency of the lumbo-pelvic-hip complex for bodybuilders and football referees. Defining factors that are related and those that are not related to their professions that can affect their efficiency of the lumbo-pelvic-hip complex.
PATIENTS AND METHODS
Materials and methods: 35 bodybuilders and 41 football referees were randomly selected in different assosiations in Lodz. The study was performed using a questionnaire and tests for the SFTR range of motion of hip joints and also a Shober test.
RESULTS
Results: It occurs that statistically the extension, flexion, abduction, external and internal rotation were significant with bodybuilders and the extension and internal rotation movement with the referees. The mean values for the Shober test when moving forward were worse for the test group than man for the control group were correct. Alongside bulking within the test group and control group the range of motion in the hip joint has decreased. The biggest statistical significance has been for the flexion and internal rotation.
CONCLUSION
Conclusions: In the group of bodybuilders the restriction appears to be in 5 out of 6 type of movements in the hip joint area: extension, flexion, abduction, internal and external rotation. In the second group, football referees the range of motion forward and internal rotation is restricted. The mobility of the lumbar region in both groups is within the average, but for the bodybuilders at quite low. The efficiency of lumbo-pelvic-hip complex is determined by duration of training, body mass, type of training and also any pain ailments. Bodybuilders have less efficiency of lumbo-pelvic-hip complex.

In a running single-leg jump (RSLJ) for distance, the generation of vertical velocity without loss of horizontal velocity during the take-off phase is ideal, but difficult; however, we hypothesized that the pelvic rotation in the frontal plane achieved it. Here we show the effect of each segment rotation on the horizontal and vertical kinetic energies ( and ) of the centre of mass (CoM) during the take-off phase of an RSLJ for distance. We collected kinematic and ground-reaction-force data during RSLJs for distance by nine male long jumpers, involving an approximately 20-m approach in an outdoor field. We determined the components of the and changes due to each segment movement. Elevation of the pelvic free-leg side increased (0.53±0.16 J/kg, 9±3% of the total change). Pelvic axial rotation decreased , while pelvic elevation did not affect it (0.01±0.02 J/kg, no significant difference from zero). In contrast, forward rotations of the stance-leg shank and thigh decreased while simultaneously increasing . The results showed that pelvic elevation increased the vertical CoM velocity without causing a loss in horizontal velocity, although the lower-limb segments' effects on the vertical and horizontal velocities exhibited a trade-off, as previously speculated. RSLJs for distance have been frequently assumed as sagittal movements. However, our findings highlight the importance of three-dimensional pelvic movement, particularly in the frontal plane, for controlling both the vertical and horizontal velocities.l We show the effect of each segment rotation on the horizontal and vertical kinetic energies ( and ) of the centre of mass during the take-off phase of a running single-leg jump for distance.l Elevation of the pelvic free-leg side increased but did not decrease , while the forward rotations of the stance-leg thigh and shank decreased , while simultaneously increasing .l We highlight the importance of pelvic movement in the frontal plane for controlling both the vertical and horizontal velocities with single-leg stance.

A 23-year-old man presented with chronic lower urinary tract symptoms and right flank pain. He had undergone ureterolithotomy a few years ago. Ultrasonography and CT of the abdomen and pelvis showed a right paravesical mass and proximal hydroureteronephrosis. Cystoscopic examination revealed a part of surgical gauze embedded in the right lateral wall of the bladder. The surgical gauze was completely retrieved with grasping forceps without any additional procedures. The patient experienced prompt relief of his symptoms and at follow-up, imaging studies revealed resolution of the pelvic mass and non-obstructed clearance of right-side collecting system. Pelvic gossypiboma with partial intravesical erosion is an unusual presentation and can be managed successfully by cystoscopic manipulation.

Review
BACKGROUND
Immunoglobulin G4-related disease (IgG4-RD) is a systemic, immune-mediated disease that can affect multiple organs, including the orbits, salivary glands, thyroid gland, lungs, aorta, pancreas, bile ducts, lymph nodes, and retroperitoneum. While timely diagnosis is particularly important given the efficacy of glucocorticoid treatment for IgG4-RD, accurate recognition can prove a challenge given the overlap between the imaging features of this disease and other entities.
PURPOSE
After a review of the epidemiology, pathophysiology, and clinical considerations (including treatment) associated with IgG4-RD, this pictorial review will showcase the variable imaging manifestations of this disease in the abdomen and pelvis. Post-treatment imaging appearance of these entities will be reviewed and mimickers of this disease in the abdomen and pelvis will be presented.
CONCLUSION
The presence of mass-like soft tissue with radiographic characteristics of fibrosis affecting multiple organs should raise suspicion for IgG4-RD, although definite diagnosis can only be made with appropriate clinical, serological, and pathologic data.

The delineation of the prostate and organs-at-risk (OARs) is fundamental to prostate radiation treatment planning, but is currently labor-intensive and observer-dependent. We aimed to develop an automated computed tomography (CT)-based multi-organ (bladder, prostate, rectum, left and right femoral heads (RFHs)) segmentation method for prostate radiation therapy treatment planning. The proposed method uses synthetic MRIs (sMRIs) to offer superior soft-tissue information for male pelvic CT images. Cycle-consistent adversarial networks (CycleGAN) were used to generate CT-based sMRIs. Dual pyramid networks (DPNs) extracted features from both CTs and sMRIs. A deep attention strategy was integrated into the DPNs to select the most relevant features from both CTs and sMRIs to identify organ boundaries. The CT-based sMRI generated from our previously trained CycleGAN and its corresponding CT images were inputted to the proposed DPNs to provide complementary information for pelvic multi-organ segmentation. The proposed method was trained and evaluated using datasets from 140 patients with prostate cancer, and were then compared against state-of-art methods. The Dice similarity coefficients and mean surface distances between our results and ground truth were 0.95 ± 0.05, 1.16 ± 0.70 mm; 0.88 ± 0.08, 1.64 ± 1.26 mm; 0.90 ± 0.04, 1.27 ± 0.48 mm; 0.95 ± 0.04, 1.08 ± 1.29 mm; and 0.95 ± 0.04, 1.11 ± 1.49 mm for bladder, prostate, rectum, left and RFHs, respectively. Mean center of mass distances was within 3 mm for all organs. Our results performed significantly better than those of competing methods in most evaluation metrics. We demonstrated the feasibility of sMRI-aided DPNs for multi-organ segmentation on pelvic CT images, and its superiority over other networks. The proposed method could be used in routine prostate cancer radiotherapy treatment planning to rapidly segment the prostate and standard OARs.

Randomized Controlled Trial
INTRODUCTION
Pelvic radiography is one of the most frequent general radiography imaging procedures. Pelvic radiography is usually performed in the supine position, but in some cases erect imaging is performed. The aim of this study was to determine whether radiation dose and image quality differ between two different erect pelvic radiographic procedures in overweight and obese patients, with and without displacement of anterior adipose tissue.
METHODS
This research was a two-part study. The first part of the study was to determine a suitable fat displacement band that would not produce artifacts on the resulting radiograph when fat tissue was displaced. The second part of the study was performed in a clinical setting on 60 overweight or obese patients (BMI ≥25) referred for erect pelvic imaging. Patients were randomly divided into two equal groups, half of which displaced adipose tissue from the region of interest and the other group did not. Waist and hip circumference, height, weight, dose-area- product (DAP), primary field size, source-to-skin distance, mAs, and kV were measured. Body Mass Index (BMI), entrance surface dose (ESD), and effective dose (ED) were then calculated. The resulting images were evaluated by three radiologists.
RESULTS
It was found that a thin cotton triangular bandage produced no visible radiographic artefacts. In the group of patients using the fat displacement protocol, a statistically significant reduction in waist circumference (4.7%), DAP (38.5%), ESD (44%) and ED (38.7%) were observed (p < 0.05). In addition, a significant (p < 0.05) increase was found for all the observed image quality criteria and overall total image score with exception of sacroiliac joint, iliac crest and pubic/ischial rami.
CONCLUSION
Based on the results, the use of the adipose tissue displacement protocol for radiography of the pelvis and hip in the erect position in overweight and obese patients is recommended.
IMPLICATIONS FOR PRACTICE
The use of cotton bands to remove adipose tissue during pelvic imaging in obese and overweight patients results in a reduction of radiation dose received by the patient and improves image quality. This technique is quick, easy, and inexpensive.

Many conditions that affect a woman's health can be evaluated through the pelvic examination. Early detection and treatment of a range of gynaecologic and non-gynaecological conditions, including unusual pelvic masses, may decrease a woman's morbidity and mortality. Here, we have a female patient in her early 20s who was found to have a mass on her first screening pelvic examination. Subsequent imaging followed by surgical resection were performed with the final diagnosis of a pelvic meningioma. Routine pelvic examinations in asymptomatic women may be more useful than merely screening for cervical cancer and sexually transmitted infections. Once detected, the differential diagnosis of a pelvic mass may include aetiologies outside of the gynaecological organ system.

OBJECTIVE
To explore the significance of digital three-dimensional reconstruction techniques in the diagnosis of female pelvic mass.
METHODS
Original computed tomographic angiography (CTA) datasets of 72 patients with pelvic mass who were hospitalized in Southern Hospital of Southern Medical University from October 2009 to October 2012 were collected. All cases were undergone the B-mode ultrasound and CTA examination, the datasets were input into the Mimics Version 10.01 software respectively to construct digital three-dimensional models of pelvic, arterial blood network, pelvic mass and organs.On the basis of without knowing the diagnosis of the disease on CTA, two gynecologists gave the final diagnosis of the disease after observing and analyzing the supply blood vessels and the relationship between the adjacent organs of pelvic mass through rotate the three-dimensional model by single-blind method. Define the postoperative pathological diagnosis as the standard, and compare the coincidence rate between the postoperative pathological diagnosis with diagnosis results on different inspections (including B ultrasound results, CTA results or the diagnosis on the three-dimensional model of pelvic mass).
RESULTS
We successfully reconstructed 72 patients' three-dimensional model which could clearly display anatomic structure of pelvic bone, abdomen and pelvic arterial branches at different levels and the anatomic relationship between the mass and main organs in the pelvis. In all cases, 56 of them preoperative B-mode ultrasound examination were consistency with the postoperative pathological diagnosis, the coincidence rate was 78%, the preoperative CTA inspection results of 58 patients were consistency with the postoperative pathological diagnosis, the coincidence rate was 81%. While the diagnosis rate of 66 patients on the basis of digital three-dimensional model were consistency with that of the postoperative pathological diagnosis, the coincidence rate was 92%. Compared the compliance rate between diagnosis of pelvic mass based on the digital three-dimensional model and preoperative B-mode ultrasound, there were significant difference(P = 0.021).While compared with the preoperative CTA examination, there was not significant difference (P = 0.054).
CONCLUSION
The pelvic three-dimensional models in vivo constructed by the digital three-dimensional reconstruction technique could visually display the source of the blood supply and the relationship between the pelvic organs, and guide to diagnosis and assess preoperatively.

A prevalent notion in the literature is that the pelvic floor muscles behave as a unitary mass. We examined this proposition experimentally. In spinal cats, we recorded EMG activity from the following pelvic floor muscles: the sphincter ani externus (SAE), the abductor caudae internus (coccygeus), and the levator ani (pubiocaudalis) muscles. The epaxial sacrocaudalis dorsalis lateralis muscle was also exposed and prepared for recording. Electrical stimulation of S2 ventral roots elicited twitch responses of the sphincter ani externus and of the sacrocaudalis dorsalis lateralis muscles. Stimulation of S3 and Cx1 ventral roots elicited responses in the other two muscles studied, the levator ani and abductor caudae internus. Thus a clear segregation of the segmental motor neuron pools innervating the different pelvic floor muscles was demonstrated. The various muscles of the pelvic floor region could be reflexly activated either individually or as a mass unit depending on the intensity of stimulation. Tactile or electrical stimulation of pudendal regions on either side of the body elicited responses of the sphincter ani externus. In contrast, activation of the levator ani and abductor caudae internus muscles could be lateralized: tactile or electrical stimulation of the dorsolateral surfaces at the base of the tail region elicited ipsilateral responses from these muscles. Section of one pudendal nerve did not alter the level of tonic activity (2 to 4/s) of the sphincter ani externus. However, bilateral section of the pudendal nerve entirely abolished both tonic activity and phasic responsiveness of the SAE without affecting the activity of the levator ani and abductor caudae internus muscles. Pudendal nerve stimulation elicited only polysynaptic reflex responses from S2 ventral roots. The results presented show that the neural apparatus of the striated musculature of the pelvic floor is capable of activating individually the different muscles that make up the system, and that the sphincter ani externus from one side, and muscles that conform the diaphragm pelvis from the other, are subserved by different neuronal circuits.
