    To compare six different parameters described in literature for estimation of pelvic tilt on an anteroposterior pelvic radiograph and to create a simple nomogram for tilt correction of prosthetic cup version in total hip arthroplasty. Simultaneous anteroposterior and lateral pelvic radiographs are taken routinely in our institution and were analyzed prospectively. The different parameters (including three distances and three ratios) were measured and compared to the actual pelvic tilt on the lateral radiograph using simple linear regression analysis. One hundred and four consecutive patients (41 men, 63 women with a mean age of 31.7 years, SD 9.2 years, range 15.7-59.1 years) were studied. The strongest correlation between pelvic tilt and one of the six parameters for both men and women was the distance between the upper border of the symphysis and the sacrococcygeal joint. The correlation coefficient was 0.68 for men (P<0.001) and 0.61 for women (P<0.001). Based on this linear correlation, a nomogram was created that enables fast, tilt-corrected cup version measurements in clinical routine use. This simple method for correcting variations in pelvic tilt on plain radiographs can potentially improve the radiologist's ability to diagnose and interpret malformations of the acetabulum (particularly acetabular retroversion and excessive acetabular overcoverage) and post-operative orientation of the prosthetic acetabulum.

  3. The screening pelvic radiograph in pediatric trauma

    International Nuclear Information System (INIS)

    Background. Pelvic radiographs are routinely obtained in adult trauma to optimise early management. In adults, pelvic fractures are associated with high early transfusion requirement, high injury severity scores and an increased incidence of other abdominal and thoracic injuries. It is unclear whether this holds true in children. Objective. To determine whether the screening pelvic radiograph is necessary in paediatric trauma. Materials and methods. The notes of all patients who presented after trauma to the Starship Children's Hospital and were triaged to the resuscitation room during 1997 were reviewed. Results of initial radiography were obtained and correlated with later imaging. Results. Our review of 444 injured children seen over a period of 1 year revealed that of 347 children who had screening pelvic radiographs, only 1 had a pelvic fracture. The fracture in this child was clinically apparent and required no specific treatment. Conclusions. The presence of a pelvic fracture is rare in injured children. By omitting screening pelvic radiographs there are potential benefits, including reduced radiation exposure to children and cost savings. Uninterpretable or abnormal clinical examination or haematuria requires further investigation, but routine screening for pelvic fracture is unnecessary. (orig.)

    Pneumothorax is a common complication following blunt chest wall trauma. In these patients, because of the restrictions regarding immobilization of the cervical spine, Anteroposterior (AP) chest radiograph is usually the most feasible initial study which is not as sensitive as the erect chest X-ray or CT chest for detection of a pneumothorax. We will present 3 case reports which serve for better understanding of the entity of occult pneumothorax. The first case is an example of a true occult ...

  5. A new tilt on pelvic radiographs: a pilot study

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate pelvic tilt on commonly performed measurements on radiography in primary protrusio acetabuli and developmental dysplasia of the hip. A dry assembled pelvis and spine skeleton was positioned in an isocentric skull unit and films exposed with increasing degrees of angulation of pelvic tilt. The films were then read by two independent readers for seven different measurements used to evaluate the hips and acetabular: acetabular line to ilioischial line, teardrop appearance, intercristal/intertuberous ratio, co-ordinates of femoral head, centre edge angle, acetabular depth/width ratio and acetabular angle. There was so much variation in the protrusio results that no formal recommendation of any standard radiographic test can be given. Only the inter tuberous distance is not effected by pelvic tilt. The acetabular angles for developmental dysplasia of the hip showed the most potential with pelvic tilt below 15 . As pelvic tilt increases, measurements used in protusio become unreliable, and computed tomography/magnetic resonance imaging are probably going to be more accurate as one can directly visualise pelvic intrusion. We recommend a lateral view to assess the degree of pelvic tilt in patients with protrusion to ensure these measurements are valid. (orig.)

    Central lucency of pelvic phleboliths is frequently observed on plain pelvic radiographs. When it is also present on noncontrast helical CT images, pelvic phleboliths may be easily diagnosed, with no suspicion of distal ureteral calculi. The objective of this study was to determine the frequency with which this phenomenon is seen on plain radiographs and noncontrast helical CT images. During a recent two-year period we identified 70 patients with renal colic who underwent both abdomino-pelvic radiography and noncontrast helical CT scanning. Radiographs were obtained at 70-85 kVp and 30-40mA; CT scans were performed within one month of plain radiography with parameters of 120 kVp, 200-220 mA, 5-mm collimation, and pitch of 1-1.6, and using soft tissue and bone window settings. With regard to the central lucency of pelvic phleboliths, as seen on both on radiographs and CT images, two experienced radiologists reached a consensus. Among the 70 patients, a total of 150 pelvic phleboliths was found. In all cases except one, pelvic radiography and noncontrast helical CT revealed the same number of phleboliths. The exception was a case in which one of two phleboliths demonstrated by CT was not seen on radiographs. Pelvic radiography revealed central lucency in 95 of these 150 phleboliths (63%), but noncontrast helical CT failed to depict a hypodense center in any phlebolith. Central lucency of pelvic phleboliths, as frequently seen on plain pelvic radiographs, was not revealed by routine noncontrast helical CT in any patient. The presence or absence of central lucency on these CT images cannot, therefore, be used to differentiate phleboliths from distal ureteral calculi. (author)

  8. Image quality in the anteroposterior cervical spine radiograph: Comparison between moving, stationary and non-grid techniques in a lamb neck

    Background: Cervical spine radiography is a commonly employed examination for degenerative disease and trauma in the cervical spine. Traditionally, the anteroposterior projection is undertaken with the use of an anti-scatter grid. Some practitioners appear to have rejected this practice in favour of a non-grid technique, possibly because of the dose saving it affords. It is necessary to determine if image quality in the cervical spine is significantly degraded and whether the omission of the grid is justified. Method: Using a slaughtered lamb neck as a model of the human neck triplicate radiographs were obtained using a non-grid, a stationary grid and a moving grid technique. Entrance surface dose and dose area product was measured for these techniques. Image quality in terms of contrast, sharpness and overall acceptability was evaluated by 9 independent and blinded observers. Results: A significant reduction in measured dose was observed when the non-grid technique was compared to stationary or moving grid techniques. A statistically significant reduction in image contrast, sharpness and acceptability was also seen in the non-grid compared to grid techniques. Conclusion: These results show evidence of significantly greater image quality in the presence of either a moving or stationary grid in the lamb model. As such they support the continued use of scatter rejection methods such as the anti-scatter grid in AP radiography of the human cervical spine, to optimise radiographic image quality in this critical structure.

    A change in the position of a prosthetic acetabular component between two different radiographic examinations indicates loosening, and may be observed as tilting or migration of the socket. To determine the apparent changes in socket position caused by improper positioning of the pelvis, a full-scale model of a pelvis with attached prosthetic sockets was examined radiographically in different positions. The projected alignment of the Charnley socket indicator wire against the inter-tuberosity line was markedly influenced by the positioning of the pelvis. An alternative way of measuring the alignment is to use the long axis of the projected ellipse of the outer circumferential groove in the socket polyethylene. The thus defined socket alignment was not influenced by the positioning of the pelvis within the investigated range. No apparent socket migration was recorded within the range of pelvic rotation and inclination studied. (orig.).

    To find a correlation between the cross-over ratio of the cross-over sign on conventional anteroposterior (AP) pelvic radiographs and retroversion measurements ('roof-edge angle' and 'equatorial-edge angle) on computed tomography (CT) scans. This would facilitate the interpretation of the cross-over sign regarding the amount of acetabular retroversion. Correctly projected AP pelvic radiographs (2,925 hips) were examined for the presence of the cross-over sign (COS), and the overlap ratio of the COS was measured. On CT scans of the same patients the 'roof-edge angle' (RE angle) and the 'equatorial-edge angle' (EE angle) were also calculated. A statistically significant but only weak relationship could be found between the overlap ratio of the COS and the 'roof-edge angle' (P < 0.0001; correlation coefficient -0.486) and between this ratio and the 'equatorial-edge angle' (P < 0.0001; correlation coefficient -0.395). A relationship between the overlap ratio and orientation measurements on CT scans could be found, but it was less strong than expected. (orig.)

    The aim of this prospective study is to validate a vector arithmetic method for measuring acetabular cup orientation after total hip arthroplasty (THA) and to verify the clinical practice. We measured cup anteversion and inclination of 123 patients after cementless primary THA twice by two examiners on AP pelvic radiographs with a vector arithmetic method and compared with a 3D-CT based reconstruction model within the same radiographic coronal plane. The mean difference between the radiographic and the 3D-CT measurements was -1.4 ±3.9 for inclination and 0.8 ±7.9 for anteversion with excellent correlation for inclination (r=0.81, p < 0.001) and moderate correlation for anteversion (r=0.65, p < 0.001). The intraclass correlation coefficient for measurements on radiographs ranged from 0.98 (95%-CI: 0.98; 0.99) for the first observer to 0.94 (95%-CI: 0.92; 0.96) for the second observer. The interrater reliability was 0.96 (95%-CI: 0.93; 0.98) for inclination and 0.93 (95%-CI: 0.85; 0.96) for anteversion. The largest errors in measurements were associated with an extraordinary pelvic tilt. In order to get a valuable measurement for measuring cup position after THA on pelvic radiographs by this vector arithmetic method, there is a need for a correct postoperative ap view, with special regards to the pelvic tilt for the future.

    Full Text Available Background/Aim. Femoroacetabular impingement, a pathophysiological mechanism of small morphological changes of the hip leads to early arthritic changes. The aim of this study was to present a simple method for the quantification of femoral head and neck junction in patients with cam form of femoroacetabular impingement, in standardized anteroposterior and profile DUNN 90 radiograms of the hips. Methods. In standardized anteroposterior and profile DUNN 90 images of the hips we determined the angle of 2 alpha, defined by our own original method. We tested 141 hips in 81 patients without clinical signs of femoroacetabular impingement, and 153 hips in 76 patients with clinically clear signs of femoroacetabular impingement. Results. The value of the angle 2 alpha in anteroposterior hip radiograms was on average 113.7° for the patients with clinical symptoms of impingement, and 84.2° for the control group of patients (p ≤ 0.0001, and in DUNN 90 profile radiography of the hip, the value of 2 alpha angle in the patients group was 97.2°, and 74.6° in the control group (p ≤ 0.0001. The proposed method of determining the angle 2 alpha showed a high level sensitivity (97.8% and specificity (98.7 and positive predictive value (98.6%. It was false positive in only 1.3%, and false negative in 2.12% of patients. Conclusion. Using standardized anteroposterior and profile radiographs of the hips, and without determination of femoral neck axis in patients with femoroacetabular impingement with the cam effect at the junction of the femoral head and neck, we proposed the method of measuring joint abnormalities of femoral head and neck junction, very capable to predict the disease development in an asymptomatic risk group of patients and high sensitive in the diagnosis of the disease in the group of patients.

  13. Optimizing bone surveys performed for suspected non-accidental trauma with attention to maximizing diagnostic yield while minimizing radiation exposure: utility of pelvic and lateral radiographs

    International Nuclear Information System (INIS)

    Skeletal surveys for non-accidental trauma (NAT) include lateral spinal and pelvic views, which have a significant radiation dose. To determine whether pelvic and lateral spinal radiographs should routinely be performed during initial bone surveys for suspected NAT. The radiology database was queried for the period May 2005 to May 2011 using CPT codes for skeletal surveys for suspected NAT. Studies performed for skeletal dysplasia and follow-up surveys were excluded. Initial skeletal surveys were reviewed to identify fractures present, including those identified only on lateral spinal and/or pelvic radiographs. Clinical information and MR imaging was reviewed for the single patient with vertebral compression deformities. Of the 530 children, 223 (42.1%) had rib and extremity fractures suspicious for NAT. No fractures were identified solely on pelvic radiographs. Only one child (<0.2%) had vertebral compression deformities identified on a lateral spinal radiograph. This infant had rib and extremity fractures and was clinically paraplegic. MR imaging confirmed the vertebral body fractures. Since no fractures were identified solely on pelvic radiographs and on lateral spinal radiographs in children without evidence of NAT, nor in nearly all with evidence of NAT, inclusion of these views in the initial evaluation of children for suspected NAT may not be warranted.

    The purpose of this study was to review the MRI examinations of a large group of low-energy trauma patients in whom pelvic MRI had detected radiographically occult fractures, in order to characterize prevailing fracture patterns and determine how often co-existing proximal femoral and pelvic fractures were observed. All patients having pelvic MRI over 5 years were identified. Word-search software selected 269 MRI reports containing the term 'fracture'. Further scrutiny identified 168 with diagnosis of fracture. MRI request and imaging record review identified 102 low-energy trauma cases that had MRI for clinical suspicion of fracture despite normal radiographs. Sixty-six cases were excluded for the following reasons: no expressed clinical suspicion of occult fracture; history suggesting high-energy trauma; skeletal co-morbidity hindering acute fracture identification; interval more than 2 weeks between radiographs and MRI. The 102 study MRI examinations, which employed a limited two-sequence protocol, were reviewed. Any fracture that had not been appreciated on radiographs was recorded and characterized as femoral, pelvic, or co-existing femoral and pelvic fractures. The 102 study cases had a median age of 82 years. The median interval between pelvic radiographs and MRI was 3 days. MRI showed undiagnosed femoral fracture in 48/102 cases (47.1%), sacral fracture in 41/102 (40.2%), and pubic fracture in 55/102 (53.9%). In 11/102 cases (10.8%), MRI showed undiagnosed fractures of both proximal femur and pelvic ring (seven sacral, six pubic bone, two other site fractures). In 10/11 cases with co-existing femoral and pelvic fractures, the femoral fracture was incomplete.

    In adults, pelvic computed tomography (CT) scanning plays an important role in the treatment of pelvic fractures; however, the role of CT scanning in the management of pediatric pelvic fractures is unclear. The purpose of this study was to investigate the efficacy of CT scanning in the management of pelvic fractures in children. One hundred three consecutive patients were identified. All patients underwent anteroposterior plain radiographic evaluation; CT scans were performed in 62. Three orthopaedic surgeons independently reviewed the plain radiographs and determined fracture classification and management. Subsequently, each observer was shown corresponding CT scans and again determined classification and management. Interobserver agreement was calculated using Kappa statistics. After the addition of CT scans, the mean changes in classification were nine (15%) and in management two (3%). Plain radiographs alone reliably predicted the need and type of operative intervention. Kappa statistics demonstrated "excellent" agreement for classification and management without and with CT scans. We reliably determined fracture classification and management based on plain radiographs alone.

    Full Text Available OBJECTIVE: To compare the existence of radiographic abnormalities in two groups of patients, those with and without hip pain. METHODS: A total 222 patients were evaluated between March 2007 and April 2009; 122 complained of groin pain, and 100 had no symptoms. The individuals in both groups underwent radiographic examinations of the hip using the following views: anteroposterior, Lequesne false profile, Dunn, Dunn 45º, and Ducroquet. RESULTS: A total of 1110 radiographs were evaluated. Female patients were prevalent in both groups (52% symptomatic, 58% asymptomatic. There were statistically significant differences between the groups in age (p<0.0001, weight (p = 0.002 and BMI (p = 0.006. The positive findings in the group with groin pain consisted of the presence of a bump on the femoral head in the anteroposterior view (p<0.0001 or in the Dunn 45º view (p = 0.008. The difference in the a angle in the anteroposterior, Dunn, Dunn 45º, and Ducroquet views for all of the cases studied was p,0.0001. The joint space measurement differed significantly between groups in the Lequesne view (p = 0.007. The Lequesne anteversion angle (ρ and the femoral offset measurement also differed significantly (p = 0.005 and p = 0.0001, respectively. CONCLUSIONS: We conclude that the best views for diagnosing a femoroacetabular impingement are the anteroposterior pelvic orthostatic, the Dunn 45º, and the Ducroquet views. The following findings correlated with hip pain: a decrease in the femoral offset, an increase in the α angle, an increase in the Lequesne ρ angle, a decrease in the CE angle of Wiberg, a thinner articular space and the presence of a bump on the femoral head-neck transition.

    Pelvic insufficiency fractures may occur in the absence of trauma or as a result of low-energy trauma in osteoporotic bone. With a growing geriatric population, the incidence of pelvic insufficiency fracture has increased over the last 3 decades and will continue to do so. These fractures can cause considerable pain, loss of independence, and economic burden to both the patient and the health care system.

  4. Femoral neck buttressing: a radiographic and histologic analysis

    International Nuclear Information System (INIS)

    Objective. To examine the incidence, radiographic and histologic findings of medial femoral neck buttressing in a consecutive group of patients undergoing total hip arthroplasty.Design. Biomechanical parameters were evaluated on standard anteroposterior pelvic radiographs of 113 patients prior to hip replacement surgery. Demographic information on all patients was reviewed and histologic evaluation was performed on specimens obtained at the time of surgery.Results. The incidence of medial femoral neck buttressing was found to be 50% in a consecutive series of patients undergoing total hip arthroplasty. The incidence was slightly higher in women (56% vs 41%). Patients with buttressing had increased neck-shaft angles and smaller femoral neck diameters than were seen in patients without buttressing. Histologic evaluation demonstrated that the buttress resulted from deposition bone by the periosteum on the femoral neck in the absence of any evidence of femoral neck fracture.Conclusion. It would appear that femoral neck buttressing occurs in response to increased joint reactive forces seen at the hip being transmitted through the femoral neck. The increased joint reactive force can be related to the increased neck shaft angle seen in patients with buttressing. (orig.)

This study aims to analyze the accuracy of the true anteroposterior view pedicle screw insertion technique in MIS-TLIF surgery, compare it with conventional pedicle screw insertion technology, and discuss its clinical application value. Methods: Fifty-two patients undergoing true anteroposterior view (group A and 87 patients undergoing conventional pedicle screw insertion (group B were diagnosed with lumbar disc herniation or lumbar spinal stenosis. Time for screw placement, intraoperative irradiation exposure, accuracy rate of pedicle screw insertion, and incidence of neurovascular injury were compared between the two groups. Results: The time for screw placement and intraoperative irradiation exposure was significantly less in group A. Penetration rates of the paries lateralis of vertebral pedicle, medial wall of vertebral pedicle, and anterior vertebral wall were 1.44%, 0%, and 2.40%, respectively, all of which were significantly lower than that in group B. No additional serious complications caused by the placement of screw were observed during the follow-up period in patients in group A, but two patients with medial penetration underwent revision for unbearable radicular pain. Conclusion: The application of true anteroposterior view pedicle screw insertion technique in MIS-TLIF surgery shortens time for screw placement and reduces the intraoperative irradiation exposure along with a higher accuracy rate of screw placement, which makes it a safe, accurate

    Objective: To investigate the factors affecting the fixation, loosening and therapeutic effect of cementless acetabular prosthesis through following up the patients with total hip arthroplasty clinically and radiographically.Methods: From February 1998 to May 1999, 139 patients (148 hips) underwent total hip arthroplasty with cementless acetabular prosthesis in our department. In this study, the clinical therapeutic effect and the anteroposterior radiographs of the pelvis and anteroposterior and lateral radiographs of the hips of 109 patients (116 hips) made before operation, at 1 week, 3, 6, and 12 months after operation and annually thereafter were analyzed retrospectively. The clinical therapeutic effects were evaluated with Harris hip score. Radiographs were used to observe the position of prostheses and the bone changes around the implant, and to measure the wearing speed and direction of the acetabular cup. All evaluations were made by an independent examiner who did not participate in the operation. The patients were followed up for 5-6 years.Results: The mean Harris score was 44 points (range, 10-70 points) before operation, but it increased to 92.4 points (range, 80-100 points) at the latest review after operation, which was significantly higher than that before operation (P<0.05). No acetabular component was revised because of infection or aseptic loosening. And no acetabular component migrated. There was no revision of fixed acetabular component because of pelvic osteolysis secondary to polyethylene wear. The mean linear wear rate was 0.15 mm per year. All the acetabular prostheses were classified as stable on the radiographs.Conclusions: In terms of fixation, total hip arthroplasty with cementless acetabular components was successful. Although there is no aseptic loosening and a low incidence of osteolysis at the latest follow-up evaluation, polyethylene wear cannot be avoided and can lead to expansile osteolysis near the cups. This kind of osteolysis

  13. CT of pelvic fractures

    International Nuclear Information System (INIS)

    Although magnetic resonance imaging has become the dominant modality for cross-sectional musculo-skeletal imaging, the widespread availability, speed, and versatility of computed tomography (CT) continue to make it a mainstay of emergency room (ER) diagnostic imaging. Pelvic ring and acetabular fractures occur as the result of significant trauma secondary to either a motor vehicle accident or a high-velocity fall. These injuries are correlated with significant morbidity and mortality, both from the complications of pelvic ring fractures and from commonly associated injuries. The most commonly used classification of pelvic and acetabular fractures has been based on conventional radiographs that are, in the majority of cases, sufficient to determine the type of injury. However, because of the complexity of pelvic and acetabular fractures, precise pathological anatomy is not easily demonstrated by routine radiographs and in many cases details of fractures are not visible. Moreover, the insufficient co-operation of the patient or the difficulty of maintaining special positions can be overcome by using computed tomography. Spiral computed tomography provides information regarding the extent of the fractures and is complementary to radiography for ascertaining the spatial arrangement of fracture fragments. Spiral computed tomography is an effective tool for understanding complex fracture patterns, particularly when combined with multi-planar reconstruction two-dimensional (MPR 2D) reformatted images or three-dimensional images (3D) images. Including these techniques of reconstruction in routine pelvic imaging protocols can change management in a significant number of cases. Subtle fractures, particularly those oriented in the axial plane, are better seen on MPR images or 3D volume-rendered images. Complex injuries can be better demonstrated with 3D volume-rendered images, and complicated spatial information about the relative positions of fracture fragments can be easily

    Evaluation of the fractured pelvis or acetabulum requires both standard radiographic evaluation as well as computed tomography (CT) imaging. The standard anterior-posterior (AP), Judet, and inlet and outlet views can now be simulated using data acquired during CT, decreasing patient discomfort, radiation exposure, and cost to the healthcare system. The purpose of this study is to compare the image quality of conventional radiographic views of the traumatized pelvis to virtual radiographs created from pelvic CT scans. Five patients with acetabular fractures and ten patients with pelvic ring injuries were identified using the orthopedic trauma database at our institution. These fractures were evaluated with both conventional radiographs as well as virtual radiographs generated from a CT scan. A web-based survey was created to query overall image quality and visibility of relevant anatomic structures. This survey was then administered to members of the Orthopaedic Trauma Association (OTA). Ninety-seven surgeons completed the acetabular fracture survey and 87 completed the pelvic fracture survey. Overall image quality was judged to be statistically superior for the virtual as compared to conventional images for acetabular fractures (3.15 vs. 2.98, p = 0.02), as well as pelvic ring injuries (2.21 vs. 1.45, p = 0.0001). Visibility ratings for each anatomic landmark were statistically superior with virtual images as well. Virtual radiographs of pelvic and acetabular fractures offer superior image quality, improved comfort, decreased radiation exposure, and a more cost-effective alternative to conventional radiographs.

    2016-07-01

    Routine posteroanterior chest radiographs and computed tomography scans are more sensitive for detecting pneumothoraces than anteroposterior chest radiographs. However, supine chest radiographs are commonly performed as part of the initial and routine assessment of trauma and critically ill patients. Rates of occult pneumothorax can be as high as 50% and have a significant impact in the mortality of these patients; thus, a prompt diagnosis of this entity is important. This pictorial essay will illustrate the pleural anatomy, explain the distribution of air within the pleural space in the supine position, and review the radiologic findings that characterize this entity.

  6. Rib fracture: Different radiographic projections

    International Nuclear Information System (INIS)

    Rib fracture is the most common thoracic injury. It is thought to be present in 10% of all traumatic injuries and in almost 40% of patients who sustained severe non-penetrating trauma. There are 12 pairs of ribs. This study reviews various methods of acquisition and reconstruction of radiographic images of traumatic rib fractures in order to determine the optimal views and to simplify rib fracture diagnostics. Eight different plain radiography pictures of ribs were performed with the patient in an erect position. The following projections were obtained in sequence: oblique at 45° or 30° angle on inspiration, oblique at 45° or 30° angle on expiration as well as 45° and 39° projections during slow and fast breathing. All radiographic examinations were performed using a Philips three-phase scanner installed at the Al- Razi Hospital in Jenin, Palestine. The results demonstrate that the 45° antero-posterior oblique projection performed on expiration is recommended for diagnostics and interpretation of traumatic rib fractures. Conclusion emerging from this study are such that for a 45° oblique view on expiration is recommended for radiographic imaging of patients with clinical signs of fracture, e.g. evaluation of lower rib fractures, while 45° oblique view during fast breathing is recommended for suspected upper rib fractures

  7. Pelvic Insufficiency Fracture After Pelvic Radiotherapy for Cervical Cancer: Analysis of Risk Factors

    International Nuclear Information System (INIS)

    Purpose: To investigate the incidence, clinical characteristics, and risk factors of pelvic insufficiency fracture (PIF) after pelvic radiotherapy (RT) in cervical cancer. Methods and Materials: Medical records and imaging studies, including bone scintigraphy, CT, and MRI of 557 patients with cervical cancer who received whole-pelvic RT between January 1998 and August 2005 were reviewed. Results: Eighty-three patients were diagnosed as having PIF after pelvic RT. The 5-year cumulative incidence of PIF was 19.7%. The most commonly involved site was the sacroiliac joint. Pelvic pain developed in 48 patients (57.8%) at diagnosis. Eleven patients (13.3%) needed admission or narcotics because of severe pain, and others had good relief of symptoms with conservative management. In univariate analysis, age ≥55 years (p < 0.001), anteroposterior/posteroanterior parallel opposing technique (p = 0.001), curative treatment (p < 0.001), and radiation dose ≥50.4 Gy (p = 0.005) were the predisposing factors for development of PIF. Concurrent chemotherapy (p = 0.78) was not significant. Multivariate analysis showed that age ≥55 years (p < 0.001), body weight <55 kg (p = 0.02), curative treatment (p = 0.03), and radiation dose ≥50.4 Gy (p = 0.04) were significant predisposing factors for development of PIF. Conclusion: The development of PIF is not rare after pelvic RT. The use of multibeam arrangements to reduce the volume and dose of irradiated pelvic bone can be helpful to minimize the risk of fracture, especially in elderly women with low body weight

  8. Imaging Evaluation of Superior Labral Anteroposterior (SLAP) Tears.

    Grubin, Jeremy; Maderazo, Alex; Fitzpatrick, Darren

    2015-10-01

    Superior labral anteroposterior (SLAP) tears are common injuries that are best evaluated with magnetic resonance arthrography (MRA), as it provides the most detailed evaluation of the bicipital labral complex. Given the variety and complexity of SLAP tears, distention of the joint with intra-articular dilute gadolinium contrast properly separates the intra-articular biceps tendon, superior labrum, glenoid cartilage and glenohumeral ligaments to optimize assessment of these structures. This allows for increased diagnostic confidence of the interpreting radiologist and provides a better road map for the surgeon prior to arthroscopy. Indirect MRA and high-field magnetic resonance imaging are sensitive and specific alternative modalities if MRA cannot be performed.

    Femoral head incongruency at skeletal maturity is associated with the development of osteoarthritis in early adulthood. Containment of the femoral head provides a larger surface area for remodelling of the collapsed femoral head and the development of spherical congruency. Triple pelvic osteotomy has a role to play in Legg-Calve-Perthes\\' disease by improving femoral head containment and preventing subluxation. This is traditionally a two-incision approach with significant associated morbidity. In our unit we perform triple osteotomies through a single anterolateral incision. To retrospectively review the clinical and radiographic outcome of children who had triple osteotomies performed through a single incision over a 4-year period. In our unit from 2003 to 2006 we performed eight triple osteotomies through a single incision in children aged between 6 and 12 years with Legg-Calve-Perthes\\' disease. The procedure was performed through a single anterolateral incision made beneath the middle of the iliac crest and carried forward according to Salter\\'s osteotomy. Image intensification was used to confirm iliac, pubic and ischial cuts. After performing a standard Salter\\'s osteotomy the acetabular fragment was free to rotate anteriorly and laterally. None of the children were casted and all were allowed immediate mobilization nonweight bearing with crutches for 6 weeks. Clinical results and hip function were measured preoperatively and postoperatively using the modified Harris hip score. The average length of hospital stay was 4.7 days. None of the children had a nonunion. The centre edge angle of Wiberg was measured on all preoperative and postoperative anteroposterior pelvic radiographs. In all our patients there was an improvement in the centre edge angle of Wiberg and in the modified Harris hip score. The preoperative modified Harris hip scores ranged from 38 to 60 and postoperatively ranged from 77 to 92. The preoperative centre edge angle of Wiberg ranged

    Cystic echinococcosis caused by Echinococcus granulosus is still an important health problem in endemic areas. Cystic echinococcosis may involve different organs or areas with the most common sites being the liver and the lungs. Pelvic involvement has previously been reported and was mainly accepted as secondary to cystic echinococcosis in other organs, isolated pelvic involvement is very rare. In this case report, we aimed to present the case with pelvic cystic mass that was finally diagnosed with isolated pelvic cystic echinococcosis in and after the operation, and we would like to draw attention to include "cystic echinococcosis" in the differential diagnosis of pelvic masses.

    Full Text Available Introduction Many authors point out that there are great differences in anthropometric studies due to racial, ethnic and population morphological characteristics. Facial type is a decisive factor when planning and setting objectives, as well as when choosing the mode of orthodontic treatment. The aim of this study was to determine the morphological characteristics of antero-posterior position of maxilla and mandible and determine the most prevalent facial type in children living in Vojvodina. Material and methods Sixty cephalograms of both males and females, with skeletal class I and harmonious facial profile, were digitized and the following skeletal measurements were calculated: SNA, SNB and ANB angles. For comparative analysis, characteristics of craniofacial complex of the tested population were compared to Bolton standards from the Broadbent-Bolton longitudinal growth study. Results A statistically significant difference of both maxillary and mandibular prognathism were present when compared to Bolton standards. This indicates more retrognathic viscerocranial structures, and more posteriorly divergent profiles (SNA=81.7o; SNB=78.23o. Conclusion Differences identified in craniofacial parameters in relation to Bolton standards show that one should carefully consider the risk of altering facial esthetics of patients from Vojvodina with extraction treatment. Whenever possible, give priority to early non-extraction treatment, in order to reach the best possible end-result within the given facial type, preserving facial esthetics.

    The specification of anteroposterior (AP) axis is a fundamental and complex patterning process that sets up the embryonic polarity and shapes a multicellular organism. This process involves the integration of distinct signaling pathways to coordinate temporal-spatial gene expression and morphogenetic movements. In the frog Xenopus, extensive embryological and molecular studies have provided major advance in understanding the mechanism implicated in AP patterning. Following fertilization, cortical rotation leads to the transport of maternal determinants to the dorsal region and creates the primary dorsoventral (DV) asymmetry. The activation of maternal Wnt/ß-catenin signaling and a high Nodal signal induces the formation of the Nieuwkoop center in the dorsal-vegetal cells, which then triggers the formation of the Spemann organizer in the overlying dorsal marginal zone. It is now well established that the Spemann organizer plays a central role in building the vertebrate body axes because it provides patterning information for both DV and AP polarities. The antagonistic interactions between signals secreted in the Spemann organizer and the opposite ventral region pattern the mesoderm along the DV axis, and this DV information is translated into AP positional values during gastrulation. The formation of anterior neural tissue requires simultaneous inhibition of zygotic Wnt and bone morphogenetic protein (BMP) signals, while an endogenous gradient of Wnt, fibroblast growth factors (FGFs), retinoic acid (RA) signaling, and collinearly expressed Hox genes patterns the trunk and posterior regions. Collectively, DV asymmetry is mostly coupled to AP polarity, and cell-cell interactions mediated essentially by the same regulatory networks operate in DV and AP patterning.

    Pelvic digit is a rare congenital anomaly of pelvis usually discovered incidentally on plain radiography. It usually develops in the soft tissue adjacent to the normal skeletal tissue. Its importance lays in its differentiation from heterotopic ossification, osteochondroma, Fong's disease and traumatic avulsion injuries of pelvis to avoid any unnecessary investigations and interventions. Here, we report a 32-year-old male presenting with complain of pain in right hip, was subjected to radiographic examination and two pelvic digits were noticed arising from the iliac bone in addition to features of osteoarthritis of hip joint. The symptomatology was attributed to osteoarthritis of hip after thorough physical examination and imaging investigations. PMID:26266172

  3. The normal radiological anteroposterior alignment of the lower limb in children

    International Nuclear Information System (INIS)

    The development of reconstructive surgery of the lower limbs aimed at multilevel correction demands a precise knowledge of the physiological variations in general radiological parameters of the lower limbs in children of various age groups. It is crucial in systemic skeletal diseases, when deformities affect limbs and the surgeon does not have an intact limb as a reference. The aim of this retrospective study was to establish the normal radiological values of lower limb parameters used in the surgical correction of deformities in children of various age groups. Teleradiographs of the lower limbs taken in children with unilateral congenital or posttraumatic deformity were retrospectively reviewed. Weight-bearing full-length anteroposterior radiographs of the entire lower extremities were taken in a standing position. The study involved 215 extremities of 208 children (93 girls and 115 boys); the ages ranged from 2 years 1 month to 15 years 11 months old. Key variables included the anatomic medial proximal femoral angle (aMPFA), anatomic lateral distal femoral angle (aLDFA), anatomic medial proximal tibial angle (aMPTA), anatomic lateral distal tibial angle (aLDTA), mechanical axis deviation (MAD), the angle formed by the femoral anatomical axis and the mechanical axis of the lower limb. The means and dynamics of variations, standard deviations (SD) and 95 % confidence intervals of each parameter were calculated for each age and gender group. Simple regression analysis was performed to determine the relationship between the patient's age and the magnitude of aMPFA, aLDFA, aMPTA and aLDTA. Simple regression analysis showed a significant inverse correlation between patient age and the magnitude of aMPFA: the correlation coefficient was -0.77. A statistically significant inverse correlation between the MAD and the angle between the anatomic femoral axis and mechanical limb axis was found: the correlation coefficient was -0.53. In general, the received values were

    International Nuclear Information System (INIS)

    Background: The mandibular foramen is of particular importance to the dentist and dental specialist as it marks the beginning of the mandibular canal, which transmits inferior alveolar nerve and vessels. The aim of this study was the localization of anteroposterior and superioinferior position of the mandibular foramen on the panoramic radiographs in adolescent and young adult in a selected sample of Pakistani population. Method: This cross Sectional study was conducted in the Orthodontic department of Dr Ishrat ul ebad khan institute of oral health science, Dow University Karachi. Material comprised 150 panoramic radiographs. The radiographs were traced on a cellophane sheet. Landmarks were marked and measurements from the centre of the mandibular foramen to other landmarks were recorded. All measurements were recorded to the nearest millimetre. Results: The mandibular foramen occupies the posterior portion of middle third on antero-posterior width of mandible. A ratio between the sides of one or almost one indicated bilateral symmetry. Conclusion: The locations of the mandibular foramen occupy the middle third of ramus maintains bilateral symmetry in human mandibles. (author)

  6. Sex-related differences in the anteroposterior diameter of the foetal cisterna magna

    International Nuclear Information System (INIS)

    Aim: To measure the anteroposterior diameter of the foetal cisterna magna and observe whether there are differences according to sex. Materials and methods: Three hundred and thirty-seven Chinese women with low-risk pregnancies and a singleton foetus between 22 and 38 weeks' gestational age were included in this retrospective study. Informed consent of the volunteer subjects and hospital authority approval were first obtained. Double-blinded for gender, the anteroposterior diameter of the cisterna magna of the foetuses was measured by transabdominal sonography. Magnetic resonance imaging (MRI) was used for those foetuses with mega cisterna magna. All of the foetuses were healthy by prenatal and postnatal examination, including physical and imaging examination. Results: The mean anteroposterior diameter of the cisterna magna of all foetuses was 8.01 ± 1.79 mm. The anteroposterior diameter of the cisterna magna had no obvious correlation with the gestational age. The mean anteroposterior diameter of the cisterna magna of 179 male foetuses was 8.63 ± 2.16 mm, and the mean anteroposterior diameter of the cisterna magna of 158 female foetuses was 7.87 ± 1.74 mm. The size difference was statistically significant (p < 0.001). In the 33 foetuses with mega cisterna magna, the number of male foetuses was greater than female foetuses, and the proportion of the foetuses with mega cisterna magna in the male group was significantly higher than the foetuses in the female group (p < 0.05). Conclusion: Male foetuses had slightly larger anteroposterior diameters of the cisterna magna than female foetuses. The study would be useful for creating normal range values for the cisterna magna of male and female foetuses

    Objective: The facial esthetics after orthodontic treatment and orthognathic surgery may be affected by the patient’s natural head position. The purpose of this study was to evaluate the natural head position for the three skeletal classes of malocclusion. Materials and Methods: Our sample consisted of 102 lateral cephalometric radiographs of patients aged 15 to 18 years; class I (n=32), class II (n=40) and class III (n=30). Nine landmarks of the craniofacial skeleton and three landmarks of the cervical vertebrae were determined. Variables consisted of two angles for cervical posture (OPT/Hor and CVT/Hor), three angles for craniofacial posture (SN/Ver, PNS-ANS/Ver, and ML/Ver ) and five for craniofacial angulation (SN/OPT, SN/CVT, PNS-ANS/OPT, PNS-ANS/CVT, ML/CVT). The data were analyzed statistically using ANOVA and post hoc tests. Results: PNS-ANS/Ver and SN/Ver differed significantly (p<0.05) among the three groups. There were no significant differences between class I and class II malocclusions for the indicator angles of cranial posture except for ML/Ver. The SN/CVT was significantly different for class I compared to class III patients. A head posture camouflaging the underlying skeletal class III was observed in our population. Conclusion: A more forward head posture was observed in skeletal class III participants compared to skeletal class I and II and that class III patients tended to incline their head more ventral compared to class I participants. These findings may have implications for the amount of jaw movements during surgery particularly in patients with a class III malocclusion. PMID:25512747

    Objective: To describe the imaging characteristics of sacrococcygeal teratomas and to review appropriate diagnostic evaluation and management. Clinical Features: 12-year-old otherwise healthy, asymptomatic female with an incidental pelvic mass found on routine scoliosis radiographs. Intervention and Outcome: The pelvic mass was further evaluated by MRI and CT scan. Management consisted of successful surgical resection with no postoperative complications. Pathology confirmed a mature, benign, sacrococcygeal teratoma. Conclusions: Chiropractors manage patients with scoliosis, which may include radiographic surveillance. Familiarity with the radiographic features of masses such as sacrococcygeal teratomas is important for prompt diagnosis and management. PMID:27069263

  17. Fast radiographic systems

    International Nuclear Information System (INIS)

    Industrial radiography can be performed with shorter exposure times, when instead of X-ray film with lead intensifying screens the radiographic paper with fluorescent screen is used. With paper radiography one can obtain lower material, equipment, and labor costs, shorter exposure and processing times, and easier radiation protection. The speed of the radiographic inspection can also be increased by the use of fluorometallic intensifying screens together with a special brand of X-ray film. Before accepting either of the two fast radiographic systems one must be sure that they can produce radiographs of adequate image quality. Therefore an investigation was performed on that subject using ISO wire IQI's and ASTM penetrameters. The radiographic image quality was tested for aluminium and steel up to 30 mm thick using various brands of radiographic paper and X-ray film with fluorometallic screens and comparing them with fast X-ray films with lead screens. Both systems give satisfactory results. (author)

    To evaluate what limitations, if any, radiographs have in detecting and characterizing the morphology of non-displaced OCLTs (size, cystic change, fragmentation, and avascular necrosis [AVN]). Thirty-three OCLTs in 32 patients were reviewed in consensus by a board-certified, fellowship-trained musculoskeletal radiologist and orthopedic surgeon, on radiographs and MRI examinations performed within 15 days of one another. Location, dimensions, and characteristics of the OCLT (fragmentation, bone marrow edema, cystic change, and necrosis) were documented on the radiographs and MRI examinations. There was an average of 7.5 days (range: 1-15 days) between the MRIs and radiographs. Eighteen (55%) medial and 15 (45%) lateral OCLTs were found; none was displaced. OCLTs were categorized into three groups: Group 1 - initially diagnosed with radiographs (4/33; 12%), Group 2 - diagnosed with radiographs only after MRI correlation (20/33; 61%), and Group 3 - not identifiable on radiographs despite MRI correlation (9/33; 27%). The dimensions of all of the lesions in Groups 1 and 2 were underestimated on radiographs. Only 1 of the 4 (25%) lesions in Group 1 and 1 of the 20 (5%) lesions in Group 2 could be measured in the anteroposterior (AP) dimension (using a lateral radiograph). The most common radiographic appearance of non-displaced OCLTs was an ''ill-defined'' lucency at the talar dome (20/33; 61%). Across all three groups, fragmentation, cystic change, and AVN were radiographically apparent in 3/10 (30%), 4/19 (21%), and 1/6 (17%) cases respectively. Compared with MRI, radiographs are limited in their evaluation of the size (particularly the AP dimension) and characteristics (fragmentation, cystic change, and AVN) of non-displaced OCLTs. The most common appearance of non-displaced OCLTs is an ''ill-defined'' lucency at the talar dome. When this appearance is also considered, the estimated retrospective sensitivity of radiographs

    Our goal is to provide an update on the results of pelvic floor rehabilitation in the treatment of urinary incontinence and genital prolapse symptoms. Pelvic floor muscle training allows a reduction of urinary incontinence symptoms. Pelvic floor muscle contractions supervised by a healthcare professional allow cure in half cases of stress urinary incontinence. Viewing this contraction through biofeedback improves outcomes, but this effect could also be due by a more intensive and prolonged program with the physiotherapist. The place of electrostimulation remains unclear. The results obtained with vaginal cones are similar to pelvic floor muscle training with or without biofeedback or electrostimulation. It is not known whether pelvic floor muscle training has an effect after one year. In case of stress urinary incontinence, supervised pelvic floor muscle training avoids surgery in half of the cases at 1-year follow-up. Pelvic floor muscle training is the first-line treatment of post-partum urinary incontinence. Its preventive effect is uncertain. Pelvic floor muscle training may reduce the symptoms associated with genital prolapse. In conclusion, pelvic floor rehabilitation supervised by a physiotherapist is an effective short-term treatment to reduce the symptoms of urinary incontinence or pelvic organ prolapse.

    Full Text Available OBJECTIVE: to determine the prevalence of radiographic signs of femoroacetabular impingement (FAI in asymptomatic adults and correlate them with data from physical examinations. METHODS: We conducted a cross-sectional study with 82 asymptomatic volunteers, 164 hips, between 40 and 60 years of age, selected by convenience. They were submitted to anamnesis and clinical examination of the hip, anteroposterior (AP pelvis radiographs with three incidences, Dunn 45° and Lequesne false profile of each hip, to measure the variables. We measured the alpha angle, anterior offset of the femoral neck, cervical diaphyseal angle, CE angle of Wiberg, acetabular index, Sharp angle, and the crossing, ischial spine and posterior wall signs. RESULTS: our sample consisted of 66% women, mean age of 50.4 years. The average alpha angle was 45.10°, SD=8.6. One quarter of the hips showed alpha angle greater than or equal to 50°; among men the prevalence was 34%, and among women, 11%. We found indicative radiographic signs of femoroacetabular impingement in 42.6% of hips, whether femoral or acetabular, and the increased alpha angle was related to the decrease in hip internal rotation (p<0.001. CONCLUSION: the radiographic findings of femoroacetabular impingement in asymptomatic patients were frequent in the studied sample. The increase in alpha angle was associated with decreased internal rotation.

    Non-specific heel pain (calcaneal apophysitis) is a common disorder, particularly in physically active growing children. Foot radiographs are usually obtained as part of the clinical evaluation in routine orthopaedic practice. However, there is still controversy about the specific findings on radiographs, and it is unclear what information is present on radiographs that may alter the diagnosis and management. The purpose of this study was to review a consecutive series of patients with the diagnosis of calcaneal apophysitis to assess the yield of routine radiographs of the foot. A prospective study was performed on 61 consecutive patients with a diagnosis of calcaneal apophysitis in a single-surgeon practice. Standard anteroposterior and lateral weight-bearing foot radiographs were obtained for each patient. Seventy-one sets of foot radiographs were reviewed to determine whether radiographs had an impact on diagnosis and management. Patients with antecedent trauma, penetrating injury, foot deformity, achilles tendonitis, bursitis and infections were excluded from the study. Seventy foot radiographs were considered to be normal. The radiographs changed the diagnosis in only one patient, in whom a simple bone cyst of the calcaneous was seen. Calcaneal apophysitis is a self-limiting disease, and patients can be treated conservatively. Neither the sclerosis nor the fragmentation of the apophysis could be used to establish the diagnosis of calcaneal apophysitis. Therefore, obtaining radiographs as an initial step in their evaluation does not seem to be justified. (orig.)

    Objective: To investigate the effects of anteroposterior cricoid spliting interposition costal grafting for moderate and severe laryngotracheal stenosis in children. Methods: From 1995 to 2005, 87 children (aged 1.2 to 14 years) with moderate and severe glottic and subglottic stenosis were retrospectively studied. They were operated with cricoid spliting laryngotracheal reconstruction in our hospital. All of 87 patients were tracheostomy-dependent before surgery. Results: Eighty-five patients (95%) were successfully decannnulated and got an effective phonation. The follow-up time was more than 5 years. The effect of operation was satisfactory and the growth and development of children was normal. Conclusion: Anteroposterior cricoid split interposition costal cartilage graft is a safe and effective treatment method formoderate and severe glottic and subglottic stenosis in children.

    Planarian flatworms can regenerate heads at anterior-facing wounds and tails at posterior-facing wounds throughout the body. How this regeneration polarity is specified has been a classic problem for more than a century. We identified a planarian gene, Smed-betacatenin-1, that controls regeneration polarity. Posterior-facing blastemas regenerate a head instead of a tail in Smed-betacatenin-1(RNAi) animals. Smed-betacatenin-1 is required after wounding and at any posterior-facing wound for polarity. Additionally, intact Smed-betacatenin-1(RNAi) animals display anteriorization during tissue turnover. Five Wnt genes and a secreted Frizzled-related Wnt antagonist-like gene are expressed in domains along the anteroposterior axis that reset to new positions during regeneration, which suggests that Wnts control polarity through Smed-betacatenin-1. Our data suggest that beta-catenin specifies the posterior character of the anteroposterior axis throughout the Bilateria and specifies regeneration polarity in planarians. PMID:18063755

    All chordates share a basic body plan and many common features of early development. Anteroposterior (AP) regions of the vertebrate neural tube are specified by a combinatorial pattern of Hox gene expression that is conserved in urochordates and cephalochordates. Another primitive feature of Hox gene regulation in all chordates is a sensitivity to retinoic acid during embryogenesis, and recent developmental genetic studies have demonstrated the essential role for retinoid signalling in verteb...

    Background Idiopathic flexible flatfoot in children most frequently improves with age and remains asymptomatic.It is a physiological variation of the normality that does not require treatment unless it becomes symptomatic.The aim of this research was to investigate the reason why some individuals with flexible flatfoot become symptomatic by analysis of the differences in the relative alignment of each segment of the foot between symptomatic and asymptomatic patients with idiopathic flexible flatfoot using radiographic measurements.Methods One hundred patients with idiopathic flexible flatfoot were retrospectively identified and divided into two groups:asymptomatic (n=50) and symptomatic (n=50).Standing anteroposterior and lateral radiographs of the foot were analyzed.Five measurements were calculated to describe the alignment of the foot.An independent-samples t-test and Logistic regression test were used for statistical analysis.Results Age and sex were similar in the two groups.The independent-samples test revealed significant differences in two parameters:the anteroposterior talonavicular coverage angle and the lateral talo-first metatarsal angle.When the Logistic regression test was performed,only the talonavicular coverage angle showed statistical significance.Conclusions The lateral displacement of the navicular bone,measured by the anteroposterior talonavicular coverage angle,seems to be related to the onset of symptoms.In individuals with otherwise normal flexible flatfoot,an increase in this angle might be an important risk factor for developing symptoms.

    Arthroplasty is the standard treatment for advanced shoulder osteoarthritis. Modern prostheses designs have modular features whose size, shaft/head and body morphology can be adjusted. Total Shoulder Arthroplasty (TSA) provides better results. A complete X-ray follow-up is essential to assess the results and evaluate the survival rates of a shoulder prosthesis. Antero-posterior at 40 deg. in both internal and external rotation (true AP view) and axillary view are recommended to assess the following parameters: orientation and translation of the humeral component, offset, size and height of the humeral head, acromio-humeral distance, distribution and fixation of the cement, stress shielding and cortical resorption, radiolucent lines, subsidence and tilt, glenoid wear and 'bone stock', prostheses instability, glenoid component shift. Shoulder hemiarthroplasty can lead to glenoid wear; the true AP film at 40 deg. of internal rotation provides the best profile of gleno-humeral joint to depict glenoid erosion. Shift of the glenoid component in TSA is identified as tilting or medial migration on true AP and axillary views in the early postoperative period (1-2 months) and at minimum of 2 years. An exhaustive radiographic analysis remains essential to monitor the prosthetic implant and detect early and late complications or risk factors of prosthetic loosening.

  15. Weld radiograph enigmas

    1986-01-01

    Weld radiograph enigmas are features observed on X-ray radiographs of welds. Some of these features resemble indications of weld defects, although their origin is different. Since they are not understood, they are a source of concern. There is a need to identify their causes and especially to measure their effect on weld mechanical properties. A method is proposed whereby the enigmas can be evaluated and rated, in relation to the full spectrum of weld radiograph indications. Thie method involves a signature and a magnitude that can be used as a quantitive parameter. The signature is generated as the diference between the microdensitometer trace across the radiograph and the computed film intensity derived from a thickness scan along the corresponding region of the sample. The magnitude is the measured difference in intensity between the peak and base line values of the signature. The procedure is demonstated by comparing traces across radiographs of a weld sample before and after the introduction of a hole and by a system based on a MacIntosh mouse used for surface profiling.

    Surgery in hemophilic patients is a challenge for the general surgeon. Hemophilic pseudotumor is a rare complication occurring in 1-2% of hemophiliacs and affecting mainly patients with severe disease or those who have developed antibodies to factor VIII or IX. A number of alternatives are available for the management of these tumors, including conservative treatment, surgical removal, percutaneous drainage, embolization, and external radiation. The only definitive treatment is surgical excision. We report a case of hemophilic pseudotumor of the pelvic bone. Treatment consisted of surgical resection after arterial embolization using factor replacement to achieve hemostasis.

    Full Text Available A 25 yr old married woman with complaints of lower abdominal pain for 2 months, was found to have a irregular nontender mass in pelvis, adherent to uterus. Her Papanicolaou smear was inflammatory. To confirm the diagnosis of either ovarian malignancy or pelvic tuberculosis made on the basis of observations during exploratory laparotomy, ovarian biopsy was taken. The imprint cytodiagnosis was tuberculosis. The patient was then managed surgically and the previous diagnosis was reconfirmed by histopathology. Imprint cytodiagnosis appears to be a valuable technique whenever facilities for frozen section are not available.

    Central venous catheters (CVCs) are commonly used in children, and inadvertent arterial or extravascular cannulation is rare but has potentially serious complications. To identify the radiographic signs of arterial placement of CVCs. We retrospectively reviewed seven cases of arterially malpositioned CVCs on chest radiograph. These cases were identified through departmental quality-assurance mechanisms and external consultation. Comparison of arterial cases was made with 127 age-matched chest radiographs with CVCs in normal, expected venous location. On each anteroposterior (AP) radiograph we measured the distance of the catheter tip from the right lateral border of the thoracic spine, and the angle of the vertical portion of the catheter relative to the midline. On each lateral radiograph we measured the angle of the vertical portion of each catheter relative to the anterior border of the thoracic spine. When bilateral subclavian catheters were present, the catheter tips were described as crossed, overlapping or uncrossed. On AP radiographs, arterially placed CVCs were more curved to the left, with catheter tip positions located farther to the left of midline than normal venous CVCs. When bilateral, properly placed venous catheters were present, all catheters crossed at the level of the superior vena cava (SVC). When one of the bilateral catheters was in arterial position, neither of the catheters crossed or the inter-catheter crossover distance was exaggerated. On lateral radiographs, there was a marked anterior angulation of the vertical portion of the catheter (mean angle 37 ± 15 standard deviation [SD] in arterial catheters versus 5.9 ± 8.3 SD in normally placed venous catheters). Useful radiographic signs suggestive of unintentional arterial misplacement of vascular catheters include leftward curvature of the vertical portion of the catheter, left-side catheter tip position, lack of catheter crossover on the frontal radiograph, as well as exaggerated

  19. Radiographic imaging of calcaneal fractures - the surgeons view point

    International Nuclear Information System (INIS)

    This paper presents a detailed description of calcaneal fractures, which are underestimated and neglected despite their relatively high frequency. In association with significant anatomic destruction of the calcaneus they lead to unsatisfactory results of fracture treatment. Radiographic features of a healthy calcaneal bone together with pathomechanism and radiographic attributes of most common fracture types are presented. The prognostic role of the posterior talo-calcaneal joint and extraarticular anatomy of the calcaneus are emphasized. Special attention is directed to the methods of calcaneal imaging, especially the most valuable in the authors opinion - lateral radiographic view and computed tomography. Other commonly used views: axial, antero-posterior or Broden, are also described, with explanation why they are rarely recommended. The widely used standard classification system for calcaneal fractures introduced by Sanders, based on computed tomography is presented. Correct x-ray imaging is the basis for further diagnostic workup and treatment, giving also valuable prognostic information. The orthopedic surgeon, who undertakes the difficult task of treating the broken calcaneus receives thorough information about bone damage, which helps to realize the consequences of injury and of possible negligence. According to the authors experience, problems discussed in this paper are rarely fully appreciated by radiologists and orthopedic surgeons resulting in, often, catastrophic consequences. (author)

    To evaluate the plain radiographic and CT findings of the necrotizing fasciitis. We retrospectively reviewed the radiologic findings of 4 cases with necrotizing fasciitis. Three cases were proven pathologically. We evaluated pattern and extent of the gas shadows in plain films. CT findings were analysed, with emphasis on : (a) gas pattern, (b) extent, (c) location and involved site, (d) associated focal abscess, and (e) swelling of the adjacent muscles. On plain radiographs, four cases showed streaky or mottled gas densities in the pelvis, three cases in the perineum, one case in the abdomen, and two cases in the thigh. On CT images, gas pattern was mottled and streaky appearance with swelling of the adjacent muscles. Gas shadows located in the extraperitoneal space in four cases, fascial layer in four cases, and subcutaneous layer in four cases. There were gas shadows in pelvic wall, perineum, abdominal wall, buttock, thigh, and scrotum. Focal low density lesion suggestive of focal abscess was not visualized. Plain radiography is useful for early diagnosis of the necrotizing fasciitis and CT is very useful for detection of precise location and extent of the disease. CT is also useful for differentiation of necrotizing fasciitis from focal abscess and cellulitis.

    There has been recent interest in radiation-induced bone injury in clinical conditions, especially for pelvic insufficiency fracture (PIF). A PIF is caused by the effect of normal or physiological stress on bone with demineralization and decreased elastic resistance. Pelvic radiotherapy (RT) can also contribute to the development of a PIF. A PIF has been regarded as a rare complication with the use of megavoltage equipment. However, recent studies have reported the incidence of PIFs as 8.2{approx}20% after pelvic RT in gynecological patients, an incidence that was higher than previously believed. The importance of understanding a PIF lies in the potential for misdiagnosis as a bony metastasis. If patients complain of pelvic pain after whole-pelvis radiation therapy, the presence of a PIF must be considered in the differential diagnosis. The use of multibeam arrangements and conformal RT to reduce the volume and dose of irradiated pelvic bone can be helpful to minimize the risk of fracture. In addition to a PIF, osteonecrosis and avascular necrosis of the femoral head can develop after radiation therapy. Osteoradionecrosis of the pelvic bone is a clinical diagnostic challenge that must be differentiated from an osseous metastasis. A post-radiation bone sarcoma can result as a long-term sequela of pelvic irradiation for uterine cervical cancer.

    The presence of an anteroposterior body axis is a fundamental feature of bilateria. Within this group, echinoderms have secondarily evolved pentameral symmetric body plans. Although all echinoderms present bilaterally symmetric larval stages, they dramatically rearrange their body axis and develop a pentaradial body plan during metamorphosis. Therefore, the location of their anteroposterior body axis in adult forms remains a contentious issue. Unlike other echinoderms, sea cucumbers present an obvious anteroposterior axis not rearranged during metamorphosis, thus representing an interesting group to study their anteroposterior axis patterning. Hox genes are known to play a broadly conserved role in anteroposterior axis patterning in deuterostomes. Here, we report the expression patterns of Hox genes from early development to pentactula stage in sea cucumber. In early larval stages, five Hox genes (AjHox1, AjHox7, AjHox8, AjHox11/13a, and AjHox11/13b) were expressed sequentially along the archenteron, suggesting that the role of anteroposterior patterning of the Hox genes is conserved in bilateral larvae of echinoderms. In doliolaria and pentactula stages, eight Hox genes (AjHox1, AjHox5, AjHox7, AjHox8, AjHox9/10, AjHox11/13a, AjHox11/13b, and AjHox11/13c) were expressed sequentially along the digestive tract, following a similar expression pattern to that found in the visceral mesoderm of other bilateria. Unlike other echinoderms, pentameral expression patterns of AjHox genes were not observed in sea cucumber. Altogether, we concluded that AjHox genes are involved in the patterning of the digestive tract in both larvae and metamorphosis of sea cucumbers. In addition, the anteroposterior axis in sea cucumbers might be patterned like that of other bilateria. PMID:26250612

  5. A study of the mandibular condyle shape on the individualized corrected the tomograph and submentovertex radiograph

    International Nuclear Information System (INIS)

    The purpose of this study was to observe mandibular condyle shape in an asymptomatic population. In order to carry out this study, 96 temporomandibular joints in 48 adults (22 males, 26 females), who were asymptomatic for temporomandibular disturbances and had no history of prosthodontic or orthodontic treatments, were selected, and radiographed using the Sectograph(Denar Co., U.S.A.) for lateral and frontal individualized corrected TMJ tomograph and submentovertex radiograph. Mandibular condyles were classified morphologically, and measured mediolateral and anteroposterior dimensions and condylar angulation. The obtained results were as follows. 1. In the classification of condyle shape on lateral tomographs, 94.8% were convex type and 5.2% were angled type. 2. In the classification of condyle shape on frontal tomographs, 45.3% were convex type, 32.0% were round type, 16.0% were flat type, and 6.7% were angled type. 3. In the classification of condyle shape on submentovertex radiographs, 34.5% were flat-convex type, 22.9% were flat-flat type, 20.8% were concave-convex type, 19.8% were convex-concave type, and flat-concave type were not observed. 4. The average mediolateral length of the condyle was 19.3 mm and the average anteroposterior length was 9.4 mm. The average angle between the long axis of condyle and the coronal plane made on submentovertex view was 19.6 degrees.

    Full Text Available Objective: One of the most important goals of orthodontic treatment is to create an esthetic, well balanced facial profile. However, the components of a well-balanced Iranian facial profile have not yet been established. The purpose of this study was to evaluate the anteroposterior lip position of the Iranian population and to compare the perception of orthodontists, dental students and orthodontic patients using a series of silhouettes with varying anteroposterior lip positions.Materials and Methods: Average female and male silhouette profiles were constructed from the profiles of 30 Iranian men and women with a normal skeletal relationship. The lips in each average profile were protruded or retruded in 2-mm increments and the 7 images were arranged randomly. Thirty orthodontists, 30 dental students and 30 orthodontic patients were asked to score each silhouette from 1 (very bad to 5 (very good.Results: Both the orthodontists and the students preferred the average profile for men and slightly more retruded lip position for women. Orthodontic patients had a wide range of preference for men and selected more retruded lip positions for women. The least-favored profile was the most protrusive in the 3 groups.Conclusion: These findings suggest that Iranian orthodontists, dental students and orthodontic patients prefer an average profile for men and slightly retruded profiles for women.

The aim of this study was to identify the artery that first is affected by early pre-atherosclerotic changes in PCOS. Methods: Twenty-nine women with PCOS aged 17 to 27 years and 26 healthy nonhyperandrogenic volunteers with regular menses (control women aged 16 to 28 years were enrolled. All PCOS patients were overweight or obese (body mass index [BMI] ≥ 25. Diagnosis of PCOS was performed in line with the 2003 Rotterdam ESHRE/ASRM-Sponsored PCOS Consensus Workshop Group. Accordingly, PCOS was defined when at least two of the following three features were present after exclusion of other etiologies: 1 oligomenorrhea and or anovulation; 2 hyperandrogenism and/or hyperandrogenemia; and 3 polycystic ovaries visible at ultrasound. Androgen excess or related disorders were excluded.

    Full Text Available PURPOSE: Our goal was to assess outcomes of a selective drain placement strategy during laparoscopic radical prostatectomy (LRP with a running urethrovesical anastomosis (RUVA using cystographic imaging in all patients. Materials and Methods: A retrospective chart review was performed for all patients undergoing LRP between January 2003 and December 2004. The anastomosis was performed using a modified van Velthoven technique. A drain was placed at the discretion of the senior surgeon when a urinary leak was demonstrated with bladder irrigation, clinical suspicion for a urinary leak was high, or a complex bladder neck reconstruction was performed. Routine postoperative cystograms were obtained. RESULTS: 208 patients underwent LRP with a RUVA. Data including cystogram was available for 206 patients. The overall rate of cystographic urine leak was 5.8%. A drain was placed in 51 patients. Of these, 8 (15.6% had a postoperative leak on cystogram. Of the 157 undrained patients, urine leak was radiographically visible in 4 (2.5%. The higher leak rate in the drained vs. undrained cohort was statistically significant (p = 0.002. Twenty-four patients underwent pelvic lymph node dissection (8 drained, 16 undrained. Three undrained patients developed lymphoceles, which presented clinically on average 3 weeks postoperatively. There were no urinomas or hematomas in either group. CONCLUSIONS: Routine placement of a pelvic drain after LRP with a RUVA is not necessary, unless the anastomotic integrity is suboptimal intraoperatively. Experienced clinical judgment is essential and accurate in identifying patients at risk for postoperative leakage. When suspicion is low, omitting a drain does not increase morbidity.

    [Purpose] The purpose of this study was to examine the association between muscle-strengthening exercises applied to the knee extensor muscles and the maintenance of standing balance in both, the anteroposterior and mediolateral directions in patients who had undergone total knee replacement. [Subjects and Methods] Thirty patients who underwent total knee replacement with bilateral artificial joints participated in this study. During the eight-week study period, the load on the knee extensors was gradually increased, and the standing balance ability was measured by differentiating the anteroposterior and mediolateral directions both, before and after the experimental period. [Results] In both, the anteroposterior and the mediolateral directions, there were statistically significant increases after the eight-week experiment, with a 29% increase in standing balance maintenance in the anteroposterior direction and a 22% increase in the mediolateral direction. [Conclusion] In patients who underwent bilateral total knee replacement, strengthening exercises applied to the knee extensor muscles with gradually increasing load positively affected standing balance in both anteroposterior and mediolateral directions.

    This report reviews the clinical and radiographic features of 40 patients who underwent visceral esophageal substitution with colon for benign or malignant lesions of the esophagus. The incidence and radiographic identification of complications are discussed. All patients were routinely examined with barium esophagrams on postoperative day 10. If an anastomotic leak was suspected clinically before this time, studies were performed using water-soluble iodinated contrast material. Follow-up barium esophagrams were obtained 1-96 months after operation (average, 60 months) in 24 patients. Eight patients (21%) demonstrated asymptomatic "jejunization" of the colonic mucosa with no attributable clinical manifestations; this finding resolved in 1-3 months, without sequelae, and has not been reported before. The spectrum of ischemic changes in the colonic segment included mucosal edema, spasm, ulceration, loss of haustration, and frank necrosis. Radiographically detectable early postoperative complications included anastomotic leak in six (three pharyngocolic, three cervical esophagocolic) and aspiration of barium into the tracheobronchial tree due to incoordinated swallowing in eight. Late postoperative complications included anastomotic narrowing (12) malfunctioning of the colon due to impaired emptying (five), recurrent aspiration pneumonia (three), small bowel obstruction (three), transhiatal herniation of small bowel through the diaphragmatic hiatus (one), and reflux into the retained bypassed esophagus (one).

  13. Radiographic findings in immunodeficiency

    International Nuclear Information System (INIS)

    This paper reviews the chest radiographs and high-resolution CT (HRCT) scans in patients with immunodeficiency disorders and define the role of HRCT. Thirty-three cases were retrospectively graded according to the consensus of two radiologists. Patients with HIV seropositivity and asthma were excluded. HRCT was performed in 12 cases with standard techniques. Diagnoses included common variable hypogammaglobulinemia (n = 19), X-linked agammaglobulinemia (n = 4), chronic mucocutaneous candidiasis (n = 4), and selective immunoglobulin g deficiencies (n = 2). Chest radiographs showed bronchiectasis in 11 of 33 cases with a predominant lower lobe distribution (82%). Nodules were present in six cases and mucus plugs in four cases. HRCT showed bronchiectasis in nine of 12 cases; in five of these nine cases, bronchiectasis was not apparent on chest radiographs. Other HRCT findings included segmental air trapping (four of 12), mucus plugs (three of 12), hazy consolidation (four of 12), nodules (five of 12), and bronchiolectasis (two of 12). Therapy was altered in seven of 12 cases in which HRCT was performed. Most pertinent to clinical management were the presence of a thymoma (n = 1) and severe focal of diffuse bronchiectasis

    Pelvic-perineal dysfunctions, are the most common diseases in women after pregnancy. Urinary incontinence and genital prolapsy, often associated, are the most important consequences of childbirth and are determined by specific alterations in the structure of neurological and musculo-fascial pelvic support.Causation is difficult to prove because symptom occur remote from delivery.Furthermore it is unclear whether changes are secondary to the method of childbirth or to the pregnancy itself.This controversy fuels the debate about whether or not women should be offered the choice of elective caesarean delivery to avoid the development of subsequent pelvic floor disfunction.But it has been demonstrated that pregnancy itself, by means of mechanical changes of pelvic statics and changes in hormones, can be a significant risk factor for these diseases. Especially is the first child to be decisive for the stability of the pelvic floor.During pregnancy, the progressive increase in volume of the uterus subject perineal structures to a major overload. During delivery, the parties present and passes through the urogenital hiatus leading to growing pressure on the tissues causing the stretching of the pelvic floor with possible muscle damage, connective tissue and / or nervous.In this article we aim to describe genitourinary post partum changes with particular attention to the impact of pregnancy or childbirth on these changes.

    Female pelvic floor dysfunction encompasses a number of highly prevalent clinical conditions such as female pelvic organ prolapse, urinary and fecal incontinence, and sexual dysfunction. The etiology and pathophysiology of those conditions are, however, not well understood. Recent technological advances have seen a surge in the use of imaging, both in research and clinical practice. Among the techniques available such as sonography, X-ray, computed tomography and magnetic resonance imaging, ultrasound is superior for pelvic floor imaging, especially in the form of perineal or translabial imaging. The technique is safe with no radiation, simple, cheap, easily accessible and provides high spatial and temporal resolutions. Translabial or perineal ultrasound is useful in determining residual urinary volume, detrusor wall thickness, bladder neck mobility and in assessing pelvic organ prolapse as well as levator function and anatomy. It is at least equivalent to other imaging techniques in diagnosing, such diverse conditions as urethral diverticula, rectal intussusception and avulsion of the puborectalis muscle. Ultrasound is the only imaging method capable of visualizing modern slings and mesh implants and may help selecting patients for implant surgery. Delivery-related levator injury seems to be the most important etiological factor for pelvic organ prolapse and recurrence after prolapse surgery, and it is most conveniently diagnosed by pelvic floor ultrasound. This review gives an overview of the methodology. Its main current uses in clinical assessment and research will also be discussed. PMID:23412016

    Pelvic cancers are among the most frequently diagnosed cancers worldwide. Treatment of patients requires a multidisciplinary approach that frequently includes radiotherapy. Gastrointestinal(GI) radiation-induced toxicity is a major complication and the transient or long-term problems, ranging from mild to very severe, arising in non-cancerous tissues resulting from radiation treatment to a tumor of pelvic origin, are actually called as pelvic radiation disease. The incidence of pelvic radiation disease changes according to the radiation technique, the length of follow up, the assessmentmethod, the type and stage of cancer and several other variables. Notably, even with the most recent radiation techniques, i.e., intensity-modulated radiotherapy, the incidence of radiation-induced GI side effects is overall reduced but still not negligible. In addition, radiation-induced GI side effects can develop even after several decades; therefore, the improvement of patient life expectancy will unavoidably increase the risk of developing radiation-induced complications. Once developed, the management of pelvic radiation disease may be challenging. Therefore, the prevention of radiation-induced toxicity represents a reasonable way to avoid a dramatic drop of the quality of life of these patients. In the current manuscript we provide an updated and practical review on the best available evidences in the field of the prevention of pelvic radiation disease.

    To assess the reliability of radiographic measurements in adults previously treated for developmental dysplasia of the hip (DDH) and to clarify whether these parameters differ according to position of the patient (supine versus standing). Fifty-one patients (41 females and 10 males) with 63 affected hips were included in the study. The mean follow-up period was 45 (44-49) years in the patients who had not undergone total hip replacement (THR). Anteroposterior radiographs of the pelvis were taken with the patient in the supine and in the standing position. Measurements used for residual hip dysplasia were center-edge (CE) angle and migration percentage (MP). The joint space width (JSW) was measured at three or four locations of the upper, weight-bearing part of the joint, and the shortest distance was termed the minimum joint space width (minJSW). One radiologist and one orthopaedic surgeon, each with more than 30 years of experience, independently measured the radiographic parameters. The limits of agreement (LOA) of the CE angle (mean interobserver difference {+-} 2SD) were within the range -8 to 7 . The LOA of the MP were in the range -8 to 8% and of the minJSW -0.6 to 1.1 mm. The mean differences in CE angle between supine and standing radiographs (supine - standing) ranged from -1.1 to 0.0 and the mean differences in MP between supine and standing positions were below 1%. The mean positional differences in minJSW were below 0.1 mm and were not statistically significant. The interobserver variations with regard to CE angle, MP, and minJSW were moderate, indicating that these are reliable measurements in clinical practice. Femoral head coverage and JSW did not significantly differ between supine and weight-bearing positions. (orig.)

    Introduction Lateral abdominal radiograph is suggested as an alternative to coronary artery computed tomography (CT) in evaluating vascular calcification. Simple scoring systems including pelvic radiograph scoring and abdominal scoring system were utilized to study their correlation with coronary artery calcification. Methods In 106 MHD patients, coronary artery CT, lateral abdominal, and pelvic radiograph were taken. The Agatston scoring system was applied to evaluate the degree of coronary artery calcification which was categorized according to Agatston coronary artery calcification score (CACS) ≥ 30, ≥100, ≥400, and ≥1000. Abdominal aortic calcification was scored by 4-scored and 24-scored systems. Pelvic artery calcification was scored by a 4-scored system. Sensitivities and specificities of abdominal aortic calcification scores and pelvic artery calcification scores to predict different categories of coronary artery calcification were analyzed. We studied the diagnostic capability of abdominal aorta calcification and pelvic artery calcification to predict different CACS categories by calculating likelihood ratios. Receiver operator characteristic curves were used to determine the area under the curve for each of these testing procedures. Findings The prevalence was 48(45.3%), 15 (14.2%), 11 (10.4%), 11 (10.4%), and 11 (10.4%) for CACs > 0, ≥30, ≥100, ≥400, and ≥1000, respectively. The degree of CACs was positively correlated with patient age, prevalence of diabetes, abdominal aorta scores, and pelvic calcification scores. The areas under the curves for different CACS by all X-ray scoring systems were above 0.70 except pelvic 4-scored system for diagnosing CACS ≥30, without significant difference (P > 0.05). Discussion Both lateral abdominal and pelvic plain radiographs were demonstrated as acceptable alternatives to CT in evaluating vascular calcification. PMID:26932162

    A unilateral maxillary splint divided into three occlusal blocks was built for eight healthy young adults. The three blocks allowed the anteroposterior location of the laterotrusive contacts to vary and to distribute the occlusal force over equivalent periodontal surfaces. The ipsilateral masseteric and temporalis electromyogram (EMG) activities were recorded with surface electrodes during maximal voluntary clenching. The elevator EMG activity with the anterior occlusal block in place was significantly lower than with the intermediate or posterior blocks. The reduction for both elevators with the intermediate block in place did not show a significant variation in comparison to the posterior block of the three blocks inserted. The elevator activity with the three occlusal blocks did not differ from that recorded with the posterior block alone. Neurophysiologic and biomechanical explanations are given related to this laterotrusive elevator muscular behavior.

    The chordate central nervous system has been hypothesized to originate from either a dorsal centralized, or a ventral centralized, or a noncentralized nervous system of a deuterostome ancestor. In an effort to resolve these issues, we examined the hemichordate Saccoglossus kowalevskii and studied the expression of orthologs of genes that are involved in patterning the chordate central nervous system. All 22 orthologs studied are expressed in the ectoderm in an anteroposterior arrangement nearly identical to that found in chordates. Domain topography is conserved between hemichordates and chordates despite the fact that hemichordates have a diffuse nerve net, whereas chordates have a centralized system. We propose that the deuterostome ancestor may have had a diffuse nervous system, which was later centralized during the evolution of the chordate lineage.

    This study attempts to reconcile the apparent differences in the reported frequency of ankylosing spondylitis and radiological sacroilitis in HLA-B27 positive individuals. Pelvic radiographs from 125 Busselton subjects were mixed with 81 other films selected to illustrate the possible range of sacroiliac changes and were graded by observers who were involved in 2 of the conflicting studies and by a 3rd independent observer. Concordance was high for advanced bilateral disease but not for unilateral and milder changes. Variation between observers and the interpretation of sacroiliac radiographs is sufficiently large to account for much of the disagreement between frequency estimates.

    Full Text Available Peritoneal tuberculosis (TB is an extrapulmonary form of presentation of tuberculosis. HIV infection is a primary risk factor for this condition. Diagnosis requires microbiological or histopathological confirmation in addition to supporting radiological imaging studies. Abdominal ultrasonography and CT are useful to obtain a radiographic diagnosis, with typical findings including diffuse peritoneal thickening, presence of ascites in varying volumes, adenopathies, and caseating nodes. We report 2 cases of patients with ascites and nodular peritoneal thickening on diagnostic images, as well as high CA-125 levels in laboratory tests. In both patients, a diagnosis of peritoneal tuberculosis was reached following a US-guided peritoneal biopsy.

    Generally, descriptions of the pelvic floor are discordant, since its complex structures and the complexity of pathological disorders of such structures; commonly the descriptions are sectorial, concerning muscles, fascial developments, ligaments and so on. On the contrary to understand completely nature and function of the pelvic floor it is necessary to study it in the most unitary view and in the most global aspect, considering embriology, philogenesy, anthropologic development and its multiple activities others than urological, gynaecological and intestinal ones. Recent acquirements succeeded in clarifying many aspects of pelvic floor activity, whose musculature has been investigated through electromyography, sonography, magnetic resonance, histology, histochemistry, molecular research. Utilizing recent research concerning not only urinary and gynecologic aspects but also those regarding statics and dynamics of pelvis and its floor, it is now possible to study this important body part as a unit; that means to consider it in the whole body economy to which maintaining upright position, walking and behavior or physical conduct do not share less than urinary, genital, and intestinal functions. It is today possible to consider the pelvic floor as a musclefascial unit with synergic and antagonistic activity of muscular bundles, among them more or less interlaced, with multiple functions and not only the function of pelvic cup closure.

    The first part of the radiographic interpretation in pulmonary radiography is the description of radiographic signs. They are presented in terms of: (i) changes in pulmonary volume and (ii) changes in pulmonary density. Changes in density should be precisely located and characterized. A protocole for the description of pulmonary changes is therefore proposed. A few words are then said on how to interprete these radiographic signs

    Thirteen groups of periapical radiographic films were evaluated to determine and compare within and between groups the effects of contamination of the fixer solution with developing solution during radiographic processing. An aluminum penetrometer was used as the radiographic object to produce different optical densities. The images were compared using radiographic density and contrast as parameters. There were significant differences between the control groups and the groups processed with a contaminated fixer solution. No statistically significant differences were observed in the intragroup comparisons. PMID:8688649

    Background: The role of radiographers with respect to image interpretation within clinical practice is well recognised. It is the expectation of the professional, regulatory and academic bodies that upon qualification, radiographers will possess image interpretation skills. Additionally, The College of Radiographers has asserted that its aspiration is for all radiographers to be able to provide an immediate written interpretation on skeletal trauma radiographs by 2010. This paper explores the readiness of radiography education programmes in the UK to deliver this expectation. Method: A postal questionnaire was distributed to 25 Higher Education Institutions in the UK (including Northern Ireland) that provided pre-registration radiography education as identified from the Society and College of Radiographers register. Information was sought relating to the type of image interpretation education delivered at pre- and post-registration levels; the anatomical range of image interpretation education; and education delivery styles. Results: A total of 19 responses (n = 19/25; 76.0%) were received. Image interpretation education was included as part of all radiographer pre-registration programmes and offered at post-registration level at 12 academic centres (n = 12/19; 63.2%). The anatomical areas and educational delivery methods varied across institutions. Conclusion: Radiography education providers have embraced the need for image interpretation education within both pre- and post-registration radiography programmes. As a result, UK education programmes are able to meet the 2010 College of Radiographers aspiration.

  14. Herniation pits in the femoral neck: a radiographic indicator of femoroacetabular impingement?

    The purpose was to assess the significance of herniation pits in the femoral neck for radiographic diagnosis of femoroacetabular impingement (FAI). Eighty hips in 62 patients (bilateral in 18) with neutral pelvic orientation were enrolled. Herniation pits were diagnosed when they were located at the anterosuperior femoral neck, close to the physis, and with a diameter of >3 mm. The five radiographic signs of FAI were used: lateral center edge angle (LCE) >39 , acetabular index (AI) {<=}0, extrusion index (EI) <25%, acetabular retroversion, and pistol-grip deformity. Patients with radiographs suggesting FAI were retrospectively correlated with their clinical symptoms. Positive radiographic signs were observed in 7 hips with LCE, 7 with AI, and 80 with EI criteria. Only 3 hips out of 80 (3.8%) showed all of the signs. The acetabular retroversion and pistol-grip deformity were seen in 12/80 and 3/80 hips, respectively. The total number of hips that met radiographic criteria for FAI, including pincer type and cam type, was 18 (23%). However, none of these hips were clinically diagnosed with FAI. All symptomatic hips (11/80) presented only with nonspecific pain, and 2 hips out of 11 showed radiographic signs of FAI. The low frequency of positive radiographic signs suggesting FAI with related symptoms among patients with herniation pits suggests that herniation pits have limited significance in the diagnosis of FAI. Therefore it can be concluded that an incidental finding of herniation pits does not necessarily imply a correlation with FAI. (orig.)

  15. A Study of Radiation Incidence Angle in Anteroposterior Cervical Vertebra Examination

    International Nuclear Information System (INIS)

    In anteroposterior projection for cervical vertebra, it is general that the incidence angle of X-ray is 15 degrees to 20 degrees to head in order to prevent overlap of mandible and occipital bone and to observe array of cervical interbody and shapes of joints. However, the angle is appropriate for foreigners that was determined by foreign literature review long ago, and there have been few researches of incidence angle for Koreans' body type. The purpose of in this study are to identify the incidence angle appropriate for Koreans and to present methodology. In order to measure the incidence angle, 1,044 patients who visited S Hospital located in Seosan were selected and measured of average length of cervical vertebra, OID, axis angle, and FID. The incidence angle was calculated from the applied formula by measuring average values per age groups and sex (see Formula 1 and 2). The average length of cervical vertebra was 6cm: the length was increased from teenagers to twenties but was decreased since thirties. The difference between males and females was around 1cm (p<.01). The OID was almost the same regardless of age groups and sex. As for axis angle, the slope was increased in teenagers and twenties, but was decreased since thirties. The difference between males and females was around 2 degrees (p<.01). The FID measurements were almost the same regardless of age groups and sex, and when the incidence angle was measured from these values, the teenagers were 15.9 degrees, the twenties were 16.9 degrees, the thirties were 16.6 degrees, the forties were 16.2 degrees, the fifties were 15.9 degrees, and the sixties were 14.5 degrees, indicating that the angle was increased from teenagers to the twenties but decreased since the thirties. While the angles of males and females were measured to be the same in the teenagers, the angle was different between males and females by 2 degrees.

The results were obtained as followings. 1) The incidence was highest in 2nd decade (29.2%) and total 65 cases consists of 35 males (53.8%) and 30 females (46.2%) in ameloblastoma. 62 cases were found in lower jaw (95.4%) and the highest site of occurrence of ameloblastoma was mandibular molar region 27 cases.(41.5%) 2) In 65 cases of ameloblastoma, 18 cases were seen in association with tooth and 15 cases (83.2%) out of those were associated with mandibular molar teeth. Mandibular molar were most frequently involved in dentigerous cyst (11/37 cases, 29.7%). 3) (a) 23 cases (35.3%) of tooth resorption were found in ameloblastoma and 11 cases (29.7%) of tooth resorption were found in dentigerous cyst. (b) 15 cases (23.1%) of tooth migration were found in ameloblastoma and 10 cases (27.0%) of tooth migration were found in dentigerous cyst. 4) Several radiographic features. (a) Monolocular type ameloblastoma were seen in 23 cases (35.4) and multilocular type of ameloblastoma were seen in 42 cases (64.6%). Monolocular type of dentigerous cyst were seen in 33 cases (89.2%) and multilocular type was seen in 4 cases. (b) Monolocular type ameloblastoma showed 20 cases (87.0%) of scalloped border but 32 cases (97.0%) of dentigerous cyst showed smooth border. (c) 34 cases (81.0%) of ameloblastoma showed honey-comb appearance, soap-bubble appearance or mixed appearance. But all 4 cases of dentigerous cyst showed multicystic appearance. (d) 12 cases (52.2%) of monolocular type ameloblastoma showed slightly increased radiopacity in surrounding bone

  19. Paediatric pelvic imaging: improvement in gonad shield placement by multidisciplinary audit

    International Nuclear Information System (INIS)

    In 1996, there were local reports of poor gonad protection for paediatric pelvic radiographs. To investigate the nature of the problem and make necessary improvements. Materials and methods: A retrospective audit of 218 paediatric pelvic radiographs was undertaken in 1997. Each radiograph was assessed for the presence of a gonad shield, appropriateness of the device and its position. A multidisciplinary team was formed with representation from radiology, radiography, orthopaedics and medical physics to investigate ways of improving technique and reducing patient dose. These included radiographer training and the introduction of digital fluoroscopy as an alternative imaging technique in follow-up patients. There were further rounds of data collection in 1998 and 1999. In round 1, a gonad shield was present in 77.9 % of boys' films and 76 % of girls' films where one should have been, increasing to 85.2 % and 85.4 % respectively by round 3 of the audit (P < 0.05). Only 31.6 % of boys' devices and 21.9 % of girls' devices were correctly positioned in round 1, increasing to 78.3 % and 94.3 %, respectively, by round 3 of the audit (P < 0.05). After round 1, no inappropriate devices were used. Audit was an effective tool in gaining the resources needed to improve technique and reduce radiation exposure in children. The multidisciplinary approach was vital in the success of this project. (orig.)

    A normal hip has a natural tendency toward stability because of both osseous and soft tissue structures. Hip motion is primarily rotational around a center of rotation. When the femoral head and its center of rotation translate, with or without rotation, the inherent stability of the femoroacetabular articulation may be lost. The spectrum of hip instability ranges from subtle microinstability to traumatic dislocation. Microinstability may be the cause or the effect of several other hip pathologies. Soft tissue contributions to stability include the static capsule, dynamic musculotendinous units, and underlying generalized connective tissue (eg, Ehlers-Danlos). Osseous contributions include multiple femoral and acetabular radiographic coverage parameters. Iatrogenic contributions include an unrepaired capsulotomy, overresection of the acetabular rim (iatrogenic dysplasia), overresection of cam osteochondroplasty, iliopsoas tenotomy, labral debridement, and ligamentum teres debridement. Patients with hip microinstability often have deep groin pain, exhibited by a C sign. These patients frequently participate in flexibility sports and activities, such as ballet, gymnastics, figure skating, and martial arts. On physical examination, generalized hypermobility syndromes should be assessed, as should loss of log-roll external rotation recoil, excessive abduction, trochanteric-pelvic impingement, and abductor fatigue. Standard imaging, including plain radiographs, magnetic resonance imaging, and computed tomography, should be analyzed for all causes of hip pain. A new plain radiograph, the splits radiograph is introduced here, consistently showing lateral femoral head translation and creation of a vacuum sign, showing hip microinstability. The splits radiograph is illustrated in a 22-year-old female dancer who presented with bilateral deep anterolateral groin pain. PMID:26730687

    The integrity of a low pelvic anastomosis is often studied radiographically before takedown of a diverting ileostomy. The aim of this study is to determine the impact of routine water-soluble enema studies (WSE) in our patient population with low pelvic anastomosis. We retrospectively reviewed the operative database for a county teaching hospital from 1998 to 2008. All patients with low pelvic anastomosis (ultralow colorectal, coloanal, and ileoanal pouch anastomosis) with diverting ileostomy who underwent subsequent takedown were identified. Fifty patients met inclusion criteria. Thirty-eight patients were evaluated by WSE and 12 were not. Twenty-five patients (66%) were noted to have normal WSE studies before ostomy takedown. Thirteen patients (26%) were noted to have abnormalities on WSE. Two stenoses were clinically significant. Water-soluble enema study was 100 per cent sensitive and 69 per cent specific for detecting significant pathology. Digital rectal examination (DRE), colonoscopy, and flexible sigmoidoscopy were also 100 per cent sensitive in detecting substantial pathology. Routine use of WSE failed to demonstrate a significant impact on patients with low pelvic anastomosis undergoing ileostomy takedown. Routine DRE and rigid proctoscopy can be used to evaluate low pelvic anastomosis. WSE can be used selectively on patients with abnormal findings. PMID:19886140

  3. Can radiographers read screening mammograms?

    International Nuclear Information System (INIS)

    AIM: To evaluate the ability of radiographers to read screening mammograms in the National Health Service Breast Screening Programme (NHSBSP). MATERIALS AND METHODS: Two radiographers read a test set of 1000 screening mammograms previously reported by a consultant radiologist. Three radiographers then acted as a second reader for 54,000 screening mammograms, their recall results are presented. Four consultant radiologists and three film reading radiographers were timed while reading 2500 mammograms each. RESULTS: When reading the test mammograms the two radiographers recalled all the cancers previously detected by the radiologist at the original screen read. They also recalled 32/90 women who subsequently presented with interval cancers. As a second reader the radiographers had similar recall and cancer detection rates to the radiologists (P > 0.05). Double reading detected 9% more cancers. The radiographers take the same length of time to film read as radiologists (P > 0.05). CONCLUSION: Radiographers are able to read screening mammograms at least as well as radiologists and do not take longer to do so. Wivell, G., et al. (2003). Clinical Radiology58, 63--67

  4. Antero-posterior EEG spectral power gradient as a correlate of extraversion and behavioral inhibition.

    Several studies have shown that individual-specific patterns of cortical spectral power distribution are relatively stable across time and experimental conditions. The antero-posterior EEG spectral power gradient (APSPG) emerged as the most prominent feature associated with important personality characteristics. In this study this phenomenon is further investigated in relation to its stability and association with different personality traits. It has been shown that APSPG is generally more pronounced during resting baseline than during inter-trial interval and post-stimulus period. Its association with personality variables is similar for different frequency bands and is mostly preserved during different experimental conditions. Relatively higher oscillatory activity in frontal than in posterior cortical sites is more frequently observed in subjects with higher behavioral inhibition (BIS) and lower Sociability. Source localization analysis showed that both high BIS/low Sociability and high APSPG are associated with higher oscillatory activity in medial cortices associated with emotion processing (mostly the cingulate gyrus). This association could be tentatively explained by higher vigilance and emotional tension in introverted and behaviorally inhibited subjects. PMID:21673979

    Full Text Available Abstract Background Fifty thousand knee replacements are performed annually in the UK at an estimated cost of £150 million. Post-operative improvement depends on a number of factors including implant design and patient associated factors. To our knowledge there are no published study's comparing the results of AP glide and rotating platform designs of LCS knee arthroplasty. Therefore we feel that a study is required to investigate and compare the effects of two types of LCS total knee arthroplasty on joint proprioception and range of motion. Methods/Design Patients will be randomised to receive either a LCS AP glide or Rotating platform prosthesis. Clinical scores (Oxford knee score, American knee society score, EuroQol, range of motion and proprioception will be assessed prior to and at 3,6, 12 and 24 months after the operation. Proprioception will be assessed in terms of absolute error angle (mean difference between the target angle and the response angle. Knee angles will be measured in degrees using an electromagnetic tracking device, Polhemus 3Space Fastrak that detects positions of sensors placed on the test limb. Student's t-test will be used to compare the mean of two groups. Discussion Evidence is lacking concerning the best prosthesis to use for patients undergoing total knee replacement. This pragmatic randomised trial will test the null hypothesis that anteroposterior glide LCS knee arthroplasty does not result in better post operative knee motion and proprioception as compared to rotating platform LCS knee.

    The novel gene ashwin was isolated in a differential display screen for genes activated or up-regulated early in neural specification. ashwin is expressed maternally and zygotically, and it is up-regulated in the neural ectoderm after the midgastrula stage. It is expressed in the neural plate and later in the embryonic brain, eyes, and spinal cord. Overexpression of ashwin in whole embryos leads to anterior truncations and other defects. However, a second Organizer does not form, and the secondary axial structures may result from splitting of the Organizer, rather than axis duplication. Morpholino oligonucleotide-mediated reduction in ashwin expression leads to lethality or abnormalities in gastrulation, as well as significant apoptosis in midgastrula embryos. Apoptosis is also observed in midgastrula embryos overexpressing ashwin. Coexpression of ashwin with the bone morphogenetic protein-4 antagonist noggin has a synergistic effect on neural-specific gene expression in isolated animal cap ectoderm. Ashwin has no previously characterized domains, although two nuclear localization signals can be identified. Orthologues have been identified in the human, mouse, chicken, and pufferfish genomes. Our results suggest that ashwin regulates cell survival and anteroposterior patterning.

    . Therefore I would like to focus on a more positive development within Danish radiography, which may be a bit overlooked in an international perspective. Over the last few years pioneers among radiographers and radiologists has taken a close look at reporting radiographers in the UK and have successfully...... implemented reporting as a part of the radiographers line of work. They report on peripheral skeleton and ultrasoundexaminations which they have done for quite some time now, and the next move will be the pelvis and the vertebral column. The implementation of the reporting radiographers has contributed...... that it is not the patient who must comply with technology, but the other way around. My point is that if reporting radiographers merely focuses on technology then they leave behind the very core of radiography, namely radiography as a caring practice, which would leave care in the hands of less educated personnel. So I...

    This article discusses the background and appraisal of endoluminal ultrasound of the pelvic floor. It provides a detailed anatomic assessment of the muscles and surrounding organs of the pelvic floor. Different anatomic variability and pathology, such as prolapse, fecal incontinence, urinary incontinence, vaginal wall cysts, synthetic implanted material, and pelvic pain, are easily assessed with endoluminal vaginal ultrasound. With pelvic organ prolapse in particular, not only is the prolapse itself seen but the underlying cause related to the anatomic and functional abnormalities of the pelvic floor muscle structures are also visualized.

    Pelvic floor dysfunctions are frequently seen in females. The human pelvic floor is a complex structure and heavily stressed throughout female life. Recent findings in the functional anatomy of the pelvic floor have led to a much better understand-ing, on the basis of which enormous improvements in the therapeutic options have arisen. The pelvic floor activity is regulated by three main muscular forces that are responsible for vaginal tension and suspension of the pelvic floor -organs, bladder and rectum. For different reasons laxity in the vagina or its supporting ligaments as a result of altered connective tissue can distort this functional anatomy. A variety of symptoms can derive from these pelvic floor dysfunctions, such as urinary urge and stress incontinence, abnormal bladder emptying, faecal incontinence, obstructive bowel disease syndrome and pelvic pain. Pelvic floor reconstruction is nowadays driven by the concept that in the case of pelvic floor symptoms restoration of the anatomy will translate into restoration of the physiology and ultimately improve the patients' symptoms. The exact surgical reconstruction of the anatomy is there-fore almost exclusively focused on the restoration of the lax pelvic floor ligaments. An exact identification of the anatomic lesions preoperatively is eminently necessary, to allow for an exact anatomic reconstruction with respect to the muscular forces of the pelvic floor.

    The objective was to determine the value of radiographs in young adults with non-acute knee symptoms who are scheduled for magnetic resonance imaging (MRI). Nine hundred and sixty-one consecutive patients aged between 16 and 45 years with knee symptoms of at least 4 weeks' duration were prospectively included in three participating hospitals. After applying exclusion criteria, 798 patients remained. Exclusion criteria were previous knee surgery (including arthroscopy) or MRI, history of rheumatoid arthritis, clinical diagnosis of retropatellar chondromalacia, contra-indication for MRI and recent trauma. We identified two groups: group A with no history of trauma (n = 332), and group B with an old (>4 weeks) history of trauma (n = 466). Patients had a standardized history taken, and underwent a physical exam, antero-posterior (AP) and lateral radiographs and MRI. We evaluated the radiographs and MRI for osseous lesions, articular surface lesions, fractures, osteoarthritis, loose bodies, bone marrow edema and incidental findings. Subsequently, patients with osseous abnormalities (Kellgren grade 1 and 2 excluded) on radiographs and a matched control group was evaluated again using MRI without radiographs. Median duration of symptoms was 20 weeks. In group A, radiographs showed 36 osseous abnormalities in 332 patients (10.8%). Only 13 of these, all Kellgren grade 1 osteoarthritis, were not confirmed on MRI. MRI showed 72 (21.7%) additional abnormalities not confirmed on radiographs. In group B, radiographs showed 40 osseous abnormalities (8.6%) in 466 patients. Only 15 of these, all Kellgren grade 1 osteoarthritis, were not confirmed on MRI. MRI showed 194 (41.6%) additional abnormalities not confirmed on radiographs. The second evaluation of MRI without radiographs in 34 patients was identical to the first MRI evaluation. Common lesions were significantly more often diagnosed with MRI than with radiographs. Radiographs should not be obtained routinely when MRI is

    The aim of this study was to evaluate the post-treatment anteroposterior and vertical alterations in skeletal Class II malocclusion with different maxillary patterns in patients treated with modified Thurow appliance. Forty-five patients (22 girls and 23 boys) with skeletal Class II and angle SN.GoGn ≤ 35 and different maxillary patterns (n = 15), as follows: retrusive (SNA84°) maxilla; mean age 9 years at pre-treatment (T1) and 9 years and 10 months at post-treatment (T2), were treated with modified Thurow cervical traction appliance, with expander screw and extraoral face bow with 10° to 20° fold in relation to the intraoral arch. Force of 500 gf was applied and use for 12 to 14 h/day, with fortnightly adjustments. Analysis of variance ANOVA followed by post-hoc Tukey and Kruskal-Wallis test, followed by Mann-Whitney were used (α = 5%). In changes obtained from stage T1 to T2, no statistically significant differences were found among the groups Protrusive, normal and retrusive maxilla for the variables SNB, SN.GoGn, 1.NA, overjet, overbite and Class II discrepancy (right and left) (p>0.05). Angular measurements SNA and ANB in the protrusive maxilla group were significantly greater than in the normal and retrusive maxilla groups (p0.05). Within the limits of this study, it may be concluded that the modified Thurow cervical traction appliance was efficient for the correction of skeletal Class II irrespective of the maxillary pattern. The mandible had no significant rotation during treatment.

    @@ Retroperitoneal hematoma is an obligatory complication in pelvic ring fracture.1 In most cases, the bleeding originates from venous vessels of the presacral plexus, small arteries and veins from fracture fragments. External fixation of the pelvis can control blood loss by reducing diastasis and dramatically decreasing the volume of the pelvis. But this tamponade effect can not prevent the presence of hematoma in the adjoining retroperitoneal space. It is well known that complication of retroperitoneal hematoma is infection and sepsis.

  17. The radiographic image: A cultural artefact?

    International Nuclear Information System (INIS)

    This article looks at the role of the radiographic images produced by diagnostic radiographers. An ethnographic study of the workplace culture in one diagnostic imaging department was undertaken using participant observation for four months and semi-structured interviews with ten key informants. One of the key themes; that of the radiographic image as a cultural artefact, is explored in this article. The radiographic image is a cultural artefact which radiographers are protective of and take ownership of. Radiographers are conscious of the quality of their images and the images are an important aspect of their work. Radiographers take criticism of their images personally. The radiographic image is a record of the interaction that occurs between the radiographer and the patient. The way in which radiographic images are viewed, used and judged is an important aspect of the role of diagnostic radiographer

    Little Leaguer's shoulder is a syndrome involving the proximal humeral epiphyseal plate. Conservative treatment usually resolves the symptoms. However, there are no reports of a radiographic follow-up study of this disease. The purpose of this study was to show the radiographic healing process of Little Leaguer's shoulder. A total of 19 male baseball players diagnosed as having Little Leaguer's shoulder were retrospectively evaluated. The mean age at first presentation was 12.7 years. External rotation anteroposterior radiographs of the shoulder were taken. All patients were treated with rest from throwing, and no throwing was recommended until remodeling was confirmed. Follow-up radiographs were taken at 1-month intervals to assess healing. All patients were observed until healing was confirmed radiographically, after which they returned to baseball. The mean follow-up period was 8.5 months. In addition to radiography, patients were asked whether they had any symptoms and whether they had been able to return to baseball. At the first examination, radiographs showed a wider epiphyseal plate of the throwing side compared with the asymptomatic contralateral shoulder. Healing was observed in all cases. Healing occurred first along the medial side and was then extended laterally. The mean time required for healing was 4.7 months. All patients were able to return to playing baseball at their pre-injury level of play and were asymptomatic when examined at the final follow-up. The healing process of Little Leaguer's shoulder advanced from medial to lateral, and healing was achieved about 5 months after initial examination. (orig.)

    Full Text Available ABSTRACT OBJECTIVE: To correlate the functional outcomes and radiographic indices of proximal humerus fractures treated using an anatomical locking plate for the proximal humerus. METHODS: Thirty-nine patients with fractures of the proximal humerus who had been treated using an anatomical locking plate were assessed after a mean follow-up of 27 months. These patients were assessed using the University of California Los Angeles (UCLA score and their range of motion was evaluated using the method of the American Academy of Orthopedic Surgeons on the operated shoulder and comparative radiographs on both shoulders. The correlation between radiographic measurements and functional outcomes was established. RESULTS: We found that 64% of the results were good or excellent, according to the UCLA score, with the following means: elevation of 124°; lateral rotation of 44°; and medial rotation of thumb to T9. The type of fracture according to Neer's classification and the patient's age had significant correlations with the range of motion, such that the greater the number of parts in the fracture and the greater the patient's age were, the worse the results also were. Elevation and UCLA score were found to present associations with the anatomical neck-shaft angle in anteroposterior view; fractures fixed with varus deviations greater than 15° showed the worst results (p < 0.001. CONCLUSION: The variation in the neck-shaft angle measurements in anteroposterior view showed a significant correlation with the range of motion; varus deviations greater than 15° were not well tolerated. This parameter may be one of the predictors of functional results from proximal humerus fractures treated using a locking plate.

    The detailed radiographic features of triploidy, a fatal congenital disorder with 69 chromosomes, have not previously been reported. Radiographs of ten liveborn infants with chromosomally confirmed triploidy showed six findings highly suggestive of this diagnosis: Harlequin orbits, small anterior fontanelle, gracile ribs, diaphyseal overtubulation of long bones, upswept clavicles and antimongoloid pelvis. Sixteen other less specific findings showed many similarities to those found in trisomy 18.

    Stapled hemorrhoidopexy is a surgical procedure used worldwide for the treatment of grade Ⅲ and Ⅳ hemorrhoids in all age groups. However, life-threatening complications occur occasionally. The following case report describes the development of pelvic sepsis after stapled hemorrhoidopexy. A literature review of techniques used to manage major septic complications after stapled hemorrhoidopexy was performed. There is no standardized treatment currently available. Stapled hemorrhoidopexy is a safe, effective and time-efficient procedure in the hands of experienced colorectal surgeons.

  5. Pelvic morphology in ischiofemoral impingement

    International Nuclear Information System (INIS)

    To assess MRI measures to quantify pelvic morphology that may predispose to ischiofemoral impingement (IFI). We hypothesized that patients with IFI have a wider interischial distance and an increased femoral neck angle compared with normal controls. The study was IRB-approved and complied with HIPAA guidelines. IFI was diagnosed based on clinical findings (hip or buttock pain) and ipsilateral edema of the quadratus femoris muscle on MRI. Control subjects did not report isolated hip/buttock pain and underwent MRI for surveillance of neoplasms or to exclude pelvic fractures. Two MSK radiologists measured the ischiofemoral (IF) and quadratus femoris (QF) distance, the ischial angle as a measure of inter-ischial distance, and the femoral neck angle. The quadratus femoris muscle was evaluated for edema. Groups were compared using ANOVA. Multivariate standard least-squares regression modeling was used to control for age and gender. The study group comprised 84 patients with IFI (53 ± 16 years, 73 female, 11 male) and 51 controls (52 ± 16 years, 33 female, 18 male). Thirteen out of 84 patients (15 %) had bilateral IFI. Patients with IFI had decreased IF and QF distance (p < 0.0001), increased ischial angle (p = 0.004), and increased femoral neck angle (p = 0.02) compared with controls, independent of age and gender. Patients with IFI have increased ischial and femoral neck angles compared with controls. These anatomical variations in pelvic morphology may predispose to IFI. MRI is a useful method of not only assessing the osseous and soft-tissue abnormalities associated with IFI, but also of quantifying anatomical variations in pelvic morphology that can predispose to IFI.

    To measure the interobserver reliability and intraobserver reproducibility of post total hip arthroplasty (THA) leg length discrepancy (LLD) measurement on radiographs as well as to evaluate its accuracy by comparing it with LLD measurement on computed tomographic scanogram (CT-scanogram). In this prospective study, postoperative LLD measurements in ten THA patients were made by four observers on anteroposterior radiographs of the pelvis (inter-teardrop line to the tip of lesser trochanter) and compared to LLD measurements made on CT-scanogram scout views of the lower limb. Two observers repeated the LLD measurements on radiographs 8 weeks after the first measurements. The interobserver reliability of the LLD measurement on plain radiographs was evaluated by comparing the measurements of the four observers and the intraobserver reproducibility by comparing the two repeated measurements made by the two observers. We found excellent interobserver reliability (mean ICC 0.83) and intraobserver reproducibility (ICC 0.90 and 0.88) of the LLD measurements on plain radiographs. There was a moderate to excellent agreement, but with wide variation of measurements among the four observers, when plain radiographic measurement was compared with CT-scanogram (ICC 0.58, 0.60, 0.71, and 0.82). Despite the excellent interobserver reliability and intraobserver reproducibility of LLD measurement on radiographs, clinicians should be aware of its limited accuracy when compared to CT-scanogram.

    Pelvic fractures are serious injuries.Death within 24 hours is most often a result of acute blood loss.The emergency management of these patients is challenging and controversial.The key issues in its management are identifying the site(s) of hemorrhage and then controlling the bleeding.Management of hemodynamically unstable patients with pelvic fracture requires a multidisciplinary team.The issues addressed in this management algorithm are diagnostic evaluation,damage control resuscitation,indications for noninvasive pelvic stabilization,preperitoneal pelvic packing and the critical decisions concerning surgical options and angiography.This review article focuses on the recent body of knowledge on those determinations.

  11. [Functional anatomy of the pelvic floor].

    Science.gov (United States)

    Yiou, René; Delmas, Vincent

    2013-01-01

    The pelvic floor is the support of the pelvic viscera. The levator ani muscle (LA) with its two bundles (pubo- and iliococcygeus) is the major component of this pelvic floor. LA is formed essentially by type I fibers (slow twitch, with high oxidative capability and presence of slow myosin) as in postural muscles. The aerobic metabolism makes LA fragile to excentric contraction and to mitochondrial dysfunction. The innervation of the pelvic floor comes from the 2nd, 3rd, 4th anterior sacral roots; denervation affects pelvic dynamism. Perineum includes the musculofascial structures under the LA: ventrally the striated sphincter of urethra and the ischiocavernosus and bulbospongiosus, caudally the fatty tissue filling the ischioanal fossa. Pelvic fascia covers the muscles ; it presents reinforcements : the uterosacral and cardinal ligaments, the arcus tendineus fascia pelvis (ATFP) and the arcus tendineus levator ani (ATLA). The pelvis statics is supported by the combined action of all this anatomical structures anteriorly forming the perineal "hammock," medially the uterosacral and cardinal ligaments, posteriorly the rectovaginal fascia and the perineal body. The angles formed by the pelvic viscera with their evacuation ducts participate to the pelvic statics. During the pelvic dynamics the modification of these angles expresses the action of the musculofascial structures.

    International Nuclear Information System (INIS)

    To define osseous landmarks on tibia radiographs in order to establish age-related normal values characterizing physiological tibial bowing in children. Five hundred and twenty-six patients aged 0-17 years with normal radiographs of the lower legs were identified and retrospectively reviewed by two blinded radiologists. In anteroposterior (ap)/lateral (lat)-views, 3 lines defined tibial length and angulation. Line-A connecting proximal to distal corner of tibial metaphysic, lines B and C corresponding to corners of tibial metaphysis. Angle A/B defines proximal, A/C distal tibial-angulation. Tibial curvature is defined by distance of line-D parallel to A and tangential to tibial cortex. Normal values were calculated with linear-regression. Intra-/Interreader agreement were tested with a Bland-Altman-plot. Intrareader-agreement: Reader 1 showed a bias of -0.1, standard-deviation of bias was 1.9 and 95 %-limits-of-agreement -3.9- 3.7. Reader 2: -0.01, 2.4 and -4.7- 4.7. Interreader: 0.2, 1.6 and -2.9- 3.3.

  17. Attitudes of radiographers to radiographer-led discharge: A survey

    International Nuclear Information System (INIS)

    Background: The traditional role of the Diagnostic Radiographer in image acquisition has gradually been extended through skill-mix, particularly to include abnormality detection. Aims: This research focused on the attitudes of Radiographers to Radiographer-led Discharge (RLD), where Radiographers discharge patients with minor injuries and perform tasks previously undertaken by Accident and Emergency staff. The effects of job role, hospital type, experience and whether RLD was used in the participant's trust were examined. Method: A multiple-indicator online questionnaire assessed attitudes to RLD. Snowball sampling was used with advertisement via emails, posters and cards, containing Quick Response (QR) codes. Statement responses were coded, with reverse coding for negative statements and total scores were calculated. A higher score represented a more positive attitude. Results: 101 questionnaires were completed (an estimated 30% response rate) and the mean total score was 84/115. 95% of participants supported radiographer involvement in abnormality detection, with 46.5% selecting RLD as the preferred system for minor injuries patients vs 48.5% preferring commenting alone. Discussion: Participants were positive about extending their role through RLD and felt confident in their image interpretation abilities, though expressed concern for the legal consequences of the role and adequate pay. Generalization of the results is limited due to the possible low response rate. Conclusion: Overall, participants demonstrated positive attitudes towards RLD but they also indicate the need for appropriate payment for any additional responsibility. These findings are promising for successful implementation of RLD, though larger-scale research including radiologists, business managers, A and E staff and patients would be beneficial. - Highlights: • 101 questionnaires were completed (an estimated 30% response rate). • 95% of participants supported radiographer involvement

  18. Innominate artery compression of the trachea in infants and children: A clinical and radiographic review of 36 cases

    International Nuclear Information System (INIS)

    The authors retrospectively reviewed the caes of 40 patients, aged 2 months to 14 years, with tracheomalacia secondary to innominate artery compression. The major indication for surgery in the 20 patients so treated, as differentiated from nonsurgically treated patients was a history of ''reflux apnea.'' Both surgically and nonsurgically treated patients had normal anteroposterior chest radiographs and abnormal tracheal narrowing at the thoracic inlet on lateral radiographs. Four patients had esophageal dilatation (three had undergone surgery for esophageal atresia repair) and one had significant gastroesophageal reflux. CT was of value in assessing tracheal dynamics in inspiration and expiration in an older patient with innominate artery compression. Eighteen of the 20 patients referred for operation underwent innominate artery suspension, and the other two underwent innominate artery reimplantation as the primary surgical procedure

    2004-06-01

    Full Text Available A captive-bred white lion cub was presented with hindquarter pain, lameness and reluctance to move. Radiographs revealed generalised osteoapenia, multiple fractures, a severely collapsed pelvic girdle, bilateral lateral bowing of the scapulae and mild kyphosis of the caudal vertebrae.Adouble cortical line, a distinct sign of osteopaenia, was repeatedly seen on the pelvic limbs, most strikingly along both femurs. Based on radiographic findings and a history of an exclusive meat diet since weaning, a diagnosis of nutritional secondary hyperparathyroidism was made. The diet was changed to a commercial kitten food and the cub was given cage rest for 6 weeks. Signs of pain abated and the cub became more active.A guarded prognosis was given for full recovery, as changes to the pelvis were considered potentially irreversible.

    Fifty-five hips undergoing acetabular reconstruction with trabecular metal (TM)-coated cup and TM augments were reviewed at an average follow up of 53.7 months (36-91). Bony defects were Paprosky type IIIA in 42 and type IIIB without pelvic discontinuity in 13 hips. The average HHS increased from 40 (27-52) preoperatively to 90.5 (61-100) postoperatively (P<0.0001). Four (7.3%) of 55 hips underwent acetabular components revision: three cases of loosening (5.4%), and one of recurrent instability (1.8%) were reported. Survival rate at 2 and 5 years was 96.4% and 92.8%. In conclusion, the use of TM-coated cups and augments could be considered an effective management of Paprosky type III defects without pelvic discontinuity providing good clinical and radiographic outcomes in the mid term.

    Objective To investigate the correlation between sagittal spinal and pelvic parameters in different types of degenerative lumbar scoliosis (DLS).Methods Standing anteroposterior and lateral radiographs of the whole spine including hip joints were carried out in 70 volunteers without spinal deformity and 110 patients with DLS.The following parameters were measured:thoracic kyphosis (TK),thoracolumbar kyphosis (TL),lumbar lordosis (LL),sagittal vertical axis (SVA),pelvic incidence (PI),pelvic tilt (PT) and sacral slope (SS).According to the sagittal spinal alignment,the patients with DLS were classified into 3 types:type Ⅰ (45 cases),type Ⅱ (48 cases) and type Ⅲ (17 cases).The sagittal spinal and pelvic parameters were compared between control group and different types of DLS group,and the relationship between the sagittal spinal parameters and pelvic parameters in different groups were also investigated.Results PI in type Ⅲ patients was lower than those in other groups; PT in type Ⅱ and Ⅲ patients was higher than those in controls and type Ⅰ patients,and there was a significant difference between type Ⅱ and Ⅲ patients; SS in type Ⅱ and Ⅲ patients was lower than those in controls and type Ⅰ patients,and there was no significant difference between type Ⅱ and Ⅲ patients.Sagittal spinal imbalance was found in 17.8% of type Ⅱ patients and 29.4% of type Ⅲ patients.There were significant correlations in sagittal spinal parameters,pelvic parameters and spinopelvic parameters in controls and type Ⅰ patients.However,in type Ⅱ and Ⅲ patients,the correlations in sagittal spinal parameters and spinopelvic parameters decreased,even disappeared,though significant correlations were still found in pelvic parameters.In any group,SVA showed a significant correlation with LL and PT,especially with PT.Conclusion The sagittal spinal alignment has a ladder-like change in patients with DLS,and the correlations in pelvic parameters and spinopelvic

  2. Retroperitoneal and pelvic infections complications

    International Nuclear Information System (INIS)

    Retroperitoneal and pelvic infections complications are the major types of genito-urinary complications in Crohn's disease. CT has been shown to be a sensitive, non invasive method of documenting these infectious complications. On the other hand, conventional studies are more sensitive than CT to detect genitourinary fistulae. Some complications may manifest few or no symptom as urinary obstruction and nephrolithiasis, detected easily by sonography. For these reasons, it is important for radiologists to be aware of the genito-urinary complications of Crohn's disease. (authors). 42 refs., 20 figs

  6. Interpreting radiographs. 1. The foot

    International Nuclear Information System (INIS)

    Radiography of the foot of a conscious standing horse is within the capability of all modern portable X-ray machines; radiographic examination of the feet of horses with long-standing lameness is frequently carried out in practice. With the introduction of modern fast intensifying screens and films there is little excuse for poor results caused by movement or the low output of portable machines. Sadly, although the foot is the most commonly radiographed part of the horse, a high percentage of the films taken are not of diagnostic quality. This is due, first, to over exposure, secondly, to poor developing techniques and thirdly, to poor positioning

    Sanicola, Shawn M; Arnold, Thomas B; Osher, Lawrence

    2002-10-01

    The medial cuneiforms and first metatarsals were identified in 515 randomly selected specimens at the Hamman-Todd osteology collection in the Cleveland Museum of Natural History in Cleveland, Ohio, and the transverse plane angulation of the hallucal tarsometatarsal joint was determined by direct measurement of the selected bones. Medial cuneiforms were subsequently separated into three categories corresponding to the amount of measured obliquity. The first tarsometatarsal joint was reassembled, and the paired medial cuneiforms and first metatarsals were radiographed at different declination angles in inverted, everted, and rectus positions. Radiographic evaluation revealed discordance between the appearance of atavism and true atavism in the cuneiform. Specifically, it was determined that the position of the hallucal tarsometatarsal joint significantly influenced the appearance of atavism in the cuneiform. It is concluded that the position of the first ray in an anteroposterior radiograph can produce the appearance of an increased obliquity angle of the medial cuneiform, resulting in an inaccurate representation of the hallucal tarsometatarsal joint.

    Full Text Available OBJECTIVE: Perform radiographic analysis of the use of Transverse Traction Device (DTT with respect to fusion rate in patients submitted to vertebral arthrodesis for degenerative lumbar diseases. METHODS: We selected x-ray images on anteroposterior, lateral and oblique views and with maximum flexion and extension dynamics of 23 patients submitted to posterolateral arthrodesis of the lumbar spine with a minimum follow-up period of six months. The images were evaluated and classified by the Linovitz's system by two spine surgeons. RESULTS: We evaluated the radiographs of 23 patients after the minimum postoperative period of 6 months and of these, 11 have used DTT. With regard to the consolidation rate, seven patients (63.6% in the group of DTT were classified as fusion as well as six patients (50% who were not submitted to the treatment. There was no statistical difference between the groups regarding the consolidation rate. CONCLUSION: The use of transverse traction device in this study showed no significant difference in the rate of consolidation in radiographic evaluation. Studies on the effective participation of this device in the stability of pedicle fixation systems are still lacking in the literature.

    [Purpose] The purpose of this study was to investigate the relationship between pelvic alignment and dysmenorrhea in general women. [Subjects and Methods] One hundred two females participated in this study. They were divided into a dysmenorrhea group and a normal group based on the results of a Visual Analogue Scale (VAS) assessment of pain and the Menstrual Distress Questionnaire (MDQ). The survey data was collecting from 5th July to 20th September, 2014. Formetric 4D was used to measure the pelvic alignment, including the values of Trunk Imbalance, Pelvic Tilt, Surface Rotation, Lateral Deviation, Kyphosis Angle, Lordosis Angle. [Results] There was a difference in the spine alignments of each group. The value of pelvic torsion was 2.4 ± 1.8 degree in those with dysmenorrhea, while it was 1.7 ± 1.1 degree in those without.

    2014-01-01

    Pelvic floor muscle exercises have been recommended for urinary incontinence since first described by obstetrician gynecologist Dr. Arnold Kegel more than six decades ago. These exercises are performed to strengthen pelvic floor muscles, provide urethral support to prevent urine leakage, and suppress urgency. In clinical urology practice, expert clinicians also teach patients how to relax the muscle to improve bladder emptying and relieve pelvic pain caused by muscle spasm. When treating lower urinary tract symptoms, an exercise training program combined with biofeedback therapy has been recommended as first-line treatment. This article provides clinical application of pelvic floor muscle rehabilitation using biofeedback as a technique to enhance pelvic floor muscle training. PMID:25233622

  16. Detection of radiographically occult-ankle fractures. Positive predictive value of post-traumatic soft-tissue swelling

    International Nuclear Information System (INIS)

    The objective of this study was to assess the value of soft-tissue swelling on plain radiographs as a predictor of radiographically occult fracture, after acute ankle injury (trauma). Patients with acute ankle trauma and plain radiographic evidence of soft-tissue swelling were included in this study. Patients were excluded if ankle trauma was sustained more than 48 hours previously or if fracture was visible on plain radiographs. All subjects (n=25) underwent computed tomography (CT) of the ankle in sagittal and coronal planes. Size of soft-tissue swelling was measured from initial Antero-posterior (AP) radiographs. The subjects in the study were placed into two groups according to whether a fracture was identified on CT or not. The results identified that those subjects without a fracture demonstrated by CT, had a soft-tissue swelling of less than 12.6 mm, while those with over 17.1mm swelling, showed a fracture on CT. Twelve patients (48 per cent) had radiographically occult fractures identified with CT. Fracture sites included: Talus/Talar Dome (n=9), posterior or lateral malleolos (n=2), distal tibia/fibula (n=1). CT detected significant soft-tissue injuries in six patients (24 per cent), composed of damaged anterior talo-fibular ligament (n=4), torn flexor tendons (n=1), and damaged fibular calcaneal ligament (n=1). One patient also showed gas in the talar dome. This study concludes that presence of a large soft-tissue swelling on plain radiographs after acute ankle trauma suggests an underlying fracture. A soft-tissue swelling of >15 mm is a reasonable threshold to prompt further imaging. Helical computed tomography provides good visualisation of subtle bone injuries and may detect clinically important soft-tissue injuries. While the study has a small sample, there is clear evidence that there is a trend worth investigating. Future research will seek to investigate a larger sample.

  17. Radiographically occult hip fracture: a reassessment of the role of conventional tomography

    International Nuclear Information System (INIS)

    Fractures of the hip and pelvis that are not readily defined on initial plain radiographs can provide both diagnostic and clinical difficulties. Historically, diagnostic protocols to define these occult fractures included repeat plain X-rays, conventional tomography and radionuclide scintigraphy (RNS). In the last 20 years Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) with 3 dimensional image reconstructions (3DCT) have been added to the algorithm, resulting in a decreased use of conventional tomography. This paper discusses the current modes of investigation for occult hip and pelvic fracture with an emphasis on the role of conventional tomography. It presents three ease studies where conventional tomography defined radiologically occult hip/pelvic fractures, resulting in better patient management. It concludes that conventional hip tomography may still have a place in current imaging protocols particularly in health facilities without access to MRI, CT or RNS.

  19. Disc height and anteroposterior translation in fused and adjacent segments after lumbar spine fusion

    Directory of Open Access Journals (Sweden)

    Frobin, Wolfgang

    2003-09-01

    Full Text Available In a series of 46 patients the effects of spinal fusion upon intervertebral height and sagittal alignment in operated and non-operated segments were retrospectively evaluated on digitized radiographs. Data was compared with age- and gender-normalized standard values. The objective was to evaluate the influence of different types of spine fusions primarily upon adjacent segments, particularly in terms of degeneration and sagittal profile of the lumbar spine. Incidence of adjacent segment degeneration (ASD is still highly controversial. However, not every degeneration adjacent to spinal fusion must be caused by the fusion and responsibility of the fusion for ASD may vary with its range and type. Distortion Corrected Roentgen Analysis (DCRA was utilized. DCRA is a proven valid, reliable, observer-independent, and accurate tool for assessment of these parameters over time and in comparison with "normal" cohorts. With this method the exact posture of the patients needs not to be known.There was little evidence for serious fusion-related ASD within an average of 40 months follow-up. No difference could be detected for rigid vs. non-rigid fusion and instrumented vs. non-instrumented techniques. Temporary postoperative distraction effects could be detected in operated and non-operated segments. Absolute preoperative values for intervertebral height and vertebral slip were age-related. Retrospectively, the choice of segments for fusion was clearly based upon radiological criteria. Thus we conclude that radiological parameters have an obvious clinical relevance for decision-making and need to be quantified. Within the limitations of this pilot study, true fusion related ASD seems to be infrequent.

    Full Text Available Introduction: Pelvic relaxation and cystocele is a common problem in middle to old age women. Transabdominal ultrasound (TAS is a noninvasive, available routine procedure in many situations. We evaluated whether TAS can predict pelvic relaxation or not. "nMaterials and Methods: In a cross sectional case- control study one hundred women 30 years or older were enrolled into the study. An expert female urologist examined the cases for the presence of signs and the grading of pelvic relaxation. A single radiologist blinded to pelvic exam results performed TAS. In the full bladder state the following criteria were recorded: 1. Bladder outlet funneling at rest and valsalva 2. Bladder base position in relation to the superior edge of the pubis symphysis 3. Bladder wall thickness 4. Pelvicaliceal system stasis 5.Post voiding residual urine ( PVR. "nResults: Bladder outlet funneling can predict pelvic relaxation (Se, 91.3%, both at rest and after valsalva. If the bladder base descent is seen below the superior edge of the pubis with the cut off point of 5 mm,it can predict pelvic relaxation. "nConclusion: TAS can be used as a safe and available modality to predict pelvic relaxation

  2. Radiology of sport injuries of pelvic apophyses

    International Nuclear Information System (INIS)

    Pelvic apophyses are places of insertion of strong muscles and tendons and are therefore places of least resistance at the end of skeletal growth. Avulsions and disruptions of pelvic apophyses can be caused by overstrain during different kinds of sport activity. Typical radiological findings in 8 different cases of ruptures of apophyses, osteochondropathies, and resulting conditions of sport injuries are demonstrated. The difficulties of correct diagnosis and different diagnosis are pointed out. The significance of hormonal impairment of ossification for development and stress factor of pelvic apophyses is exposed. Questions of treatment and follow-up studies are discussed. (orig.)

    Tao Ying, Qin Li, Lian Xu, Feifei Liu, Bing Hu

    2012-01-01

    Full Text Available The present study investigated the morphology and structure of pelvic floor in 50 nulliparous and 50 pelvic organ prolapse (POP women using translabial three-dimensional (3D ultrasound. The levator hiatus in POP women was significantly different from that in nullipara women. In POP women, the size of pelvic floor increased, with a circular shape, and the axis of levator hiatus departed from the normal position in 36 (72% cases. The puborectalis was avulsed in 18 (36% cases and the pelvic organs arranged abnormally in 23 (46% cases. In summary, 3D ultrasound is an effective tool to detect the pelvic floor in POP women who presented with abnormalities in the morphology and structure of pelvic floor.

  6. Pelvic morphology, body posture and standing balance characteristics of adolescent able-bodied and idiopathic scoliosis girls.

    Directory of Open Access Journals (Sweden)

    Georgios A Stylianides

    Full Text Available The purpose of this study was to determine how pelvic morphology, body posture, and standing balance variables of scoliotic girls differ from those of able-bodied girls, and to classify neuro-biomechanical variables in terms of a lower number of unobserved variables. Twenty-eight scoliotic and twenty-five non-scoliotic able-bodied girls participated in this study. 3D coordinates of ten anatomic body landmarks were used to describe pelvic morphology and trunk posture using a Flock of Birds system. Standing balance was measured using a force plate to identify the center of pressure (COP, and its anteroposterior (AP and mediolateral (ML displacements. A multivariate analysis of variance (MANOVA was performed to determine differences between the two groups. A factor analysis was used to identify factors that best describe both groups. Statistical differences were identified between the groups for each of the parameter types. While spatial orientation of the pelvis was similar in both groups, five of the eight trunk postural variables of the scoliotic group were significantly different that the able-bodied group. Also, five out of the seven standing balance variables were higher in the scoliotic girls. Approximately 60% of the variation is supported by 4 factors that can be associated with a set of variables; standing balance variables (factor 1, body posture variables (factor 2, and pelvic morphology variables (factors 3 and 4. Pelvic distortion, body posture asymmetry, and standing imbalance are more pronounced in scoliotic girls, when compared to able-bodied girls. These findings may be beneficial when addressing balance and ankle proprioception exercises for the scoliotic population.

    2012-01-01

    Myofascial pelvic pain (MFPP) is a major component of chronic pelvic pain (CPP) and often is not properly identified by health care providers. The hallmark diagnostic indicator of MFPP is myofascial trigger points in the pelvic floor musculature that refer pain to adjacent sites. Effective treatments are available to reduce MFPP, including myofascial trigger point release, biofeedback, and electrical stimulation. An interdisciplinary team is essential for identifying and successfully treating MFPP.

  12. Pelvic Surgical Site Infections in Gynecologic Surgery

    Directory of Open Access Journals (Sweden)

    Mark P. Lachiewicz

    2015-01-01

    Full Text Available The development of surgical site infection (SSI remains the most common complication of gynecologic surgical procedures and results in significant patient morbidity. Gynecologic procedures pose a unique challenge in that potential pathogenic microorganisms from the skin or vagina and endocervix may migrate to operative sites and can result in vaginal cuff cellulitis, pelvic cellulitis, and pelvic abscesses. Multiple host and surgical risk factors have been identified as risks that increase infectious sequelae after pelvic surgery. This paper will review these risk factors as many are modifiable and care should be taken to address such factors in order to decrease the chance of infection. We will also review the definitions, microbiology, pathogenesis, diagnosis, and management of pelvic SSIs after gynecologic surgery.

  13. Accuracy of radiographer plain radiograph reporting in clinical practice: a meta-analysis

    International Nuclear Information System (INIS)

    AIM: To determine the accuracy of radiographer plain radiograph reporting in clinical practice. MATERIALS AND METHODS: Studies were identified from electronic sources and by hand searching journals, personal communication and checking reference lists. Eligible studies assessed radiographers' plain radiograph reporting in clinical practice compared with a reference standard, and provided accuracy data to construct 2x2 contingency tables. Data were extracted on study eligibility and characteristics, quality and accuracy. Summary estimates of sensitivity and specificity and receiver operating characteristic curves were used to pool the accuracy data. RESULTS: Radiographers compared with a reference standard, report plain radiographs in clinical practice at 92.6% and 97.7% sensitivity and specificity, respectively. Studies that compared selectively trained radiographers and radiologists of varying seniority against a reference standard showed no evidence of a difference between radiographer and radiologist reporting accuracy of accident and emergency plain radiographs. Selectively trained radiographers were also found to report such radiographs as accurately as those not solely from accident and emergency, although some variation in reporting accuracy was found for different body areas. Training radiographers improved their accuracy when reporting normal radiographs. CONCLUSION: This study systematically synthesizes the literature to provide an evidence-base showing that radiographers can accurately report plain radiographs in clinical practice

    The radiographic testing is an important non-destructive testing method, especially in industrial areas where people could be injured in case of failing of a component. There it is a mighty method to find volumetric defects. As bigger the penetrated length of the defect in the component is, as bigger is the radiographic contrast. The detectability of volumetric defects in its turn is not only depending on the contrast but also on the noise, the defect area and its shape. The currently applied POD approach uses mostly only the contrast and the noise as detection threshold. This does not reflect accurately the results of evaluations by human observers. A new approach is introduced, using the widely applied POD evaluation and additionally a detection threshold depending on the area of the defect. The presentation shows the process of calculating the POD curves with simulated data by the modeling software aRTist and with artificial reference data. This approach was developed within a joint project with the company POSIVA, which is constructing a final depository for high active nuclear fuels in Finland. Radiographic testing is one of the NDT-methods they use to test the electron beam welds of the copper canisters. The copper canisters will be used in the depository as a corrosion barrier within the waste management concept. (Published as a poster session.)

  15. Automating the radiographic NDT process

    International Nuclear Information System (INIS)

    Automation, the removal of the human element in inspection, has not been generally applied to film radiographic NDT. The justication for automating is not only productivity but also reliability of results. Film remains in the automated system of the future because of its extremely high image content, approximately 8 x 109 bits per 14 x 17. The equivalent to 2200 computer floppy discs. Parts handling systems and robotics applied for manufacturing and some NDT modalities, should now be applied to film radiographic NDT systems. Automatic film handling can be achieved with the daylight NDT film handling system. Automatic film processing is becoming the standard in industry and can be coupled to the daylight system. Robots offer the opportunity to automate fully the exposure step. Finally, computer aided interpretation appears on the horizon. A unit which laser scans a 14 x 17 (inch) film in 6 - 8 seconds can digitize film information for further manipulation and possible automatic interrogations (computer aided interpretation). The system called FDRS (for Film Digital Radiography System) is moving toward 50 micron (*approx* 16 lines/mm) resolution. This is believed to meet the need of the majority of image content needs. We expect the automated system to appear first in parts (modules) as certain operations are automated. The future will see it all come together in an automated film radiographic NDT system (author)

    The purpose of this study was to obtain information on the clinical and radiographic features of the odontomas in the jaws. For this study, the authors examined and analyzed the clinical records and radiographs of 119 patients who had lesion of odontoma diagnosed by clinical and radiographic examinations. The obtained results were as follows: 1. Odontoma occurred the most frequently in the 2nd decade (45.4%) and occurred more frequently in males (60.5%) than in females (39.5%). 2. The most common clinical symptom was the delayed eruption of the teeth (34.2%). 3. The type of lesions was mainly observed as compound odontoma (80.8%), and internal pattern of the complex odontoma was unevenly radiopaque (73.9%). 4. The compound odontoma frequently occurred in anterior portion of the maxilla (57.7%) and mandible (30.9%), and complex odontoma frequently occurred in anterior portion of maxilla (34.8%) and posterior portion of mandible (30.5%). 5. The effects on adjacent teeth were impaction of teeth (71.7%) and prolonged retention of deciduous teeth (31.7%). 6. The impaction of the teeth occurred in anterior portion of maxilla (44.2%) amd mandible (19.2%), but root resorption of the adjacent teeth were not seen. 7. The boundary to adjacent structure was well-defined , the lesions appear as radiopaque mass with radiolucent rim.

    The pelvic exam is a procedure frequently complicated by difficult communication, sexual tension, and iatrogenic pain. Observations of family practice residents performing pelvic exams were done to identify ways in which they deal with these issues. Among the majority of residents, there was a failure to identify and deal with patients' discomfort. Several episodes of behavior felt to be dysfunctional to the doctor-patient relationship were observed. Implications of these findings for medical education are discussed. PMID:2323497

    2001-05-01

    Background. An audit of paediatric pelvic radiographs identified deficiencies in gonad shield placement and radiographic technique. Objective. A technique using grid-controlled fluoroscopy (GCF), with hard copy images in frame grab and digital spot image (DSI) format was evaluated to optimise gonad shield placement and reduce the dose given to children with Perthes disease and Developmental Hip Dysplasia (DDH) attending for pelvic radiography. Materials and methods. Phantom and patient dose surveys of conventional and fluoroscopic techniques were carried out. Image quality and radiation dose were compared for the frame grab and DSI techniques. Retrospective evaluation was undertaken to compare their clinical acceptability. Results. Both fluoroscopic techniques gave considerably less radiation than conventional non-grid radiography (67-83 %, P < 0.05). The frame grab technique gave less radiation than DSI (P < 0.05). There was no significant difference in the clinical acceptability scores of the DSI and frame grab images. Conclusion. Fluoroscopy acquired images are now used since the fluoroscopic techniques give much less dose than conventional radiography and provide images of sufficient quality for clinical assessment. Indeed, as there was no significant difference in clinical usefulness between the frame grab and DSI techniques, it is planned to use frame grab alone, thus gaining additional dose saving. (orig.)

    Progression of hip displacement is common in patients with cerebral palsy (CP). We aimed to investigate the rate of progression of hip displacement in patients with CP by assessing changes in radiographic indices according to Gross Motor Function Classification System (GMFCS) level during hip surveillance. We analyzed the medical records of patients with CP aged < 20 years who underwent at least 6 months interval of serial hip radiographs before any surgical hip intervention, including reconstructive surgery. After panel consensus and reliability testing, radiographic measurements of migration percentage (MP), neck-shaft angle (NSA), acetabular index (AI), and pelvic obliquity (PO) were obtained during hip surveillance. For each GMFCS level, annual changes in radiographic indices were analyzed and adjusted for affecting factors, such as sex, laterality, and type of CP. A total of 197 patients were included in this study, and 1,097 radiographs were evaluated. GMFCS classifications were as follows: 100 patients were level I-III, 48 were level IV, and 49 were level V. MP increased significantly over the duration of hip surveillance in patients with GMFCS levels I-III, IV, and V by 0.3%/year (P < 0.001), 1.9%/year (P < 0.001), and 6.2%/year (P < 0.001), respectively. In patients with GMFCS level IV, NSA increased significantly by 3.4°/year (P < 0.001). Our results suggest that periodic monitoring and radiographic hip surveillance is warranted for patients with CP, especially those with GMFCS level IV or V. Furthermore, physicians can predict and inform parents or caregivers regarding the progression of hip displacement in patients with CP. PMID:27366015

    Progression of hip displacement is common in patients with cerebral palsy (CP). We aimed to investigate the rate of progression of hip displacement in patients with CP by assessing changes in radiographic indices according to Gross Motor Function Classification System (GMFCS) level during hip surveillance. We analyzed the medical records of patients with CP aged < 20 years who underwent at least 6 months interval of serial hip radiographs before any surgical hip intervention, including reconstructive surgery.

    Full Text Available The pelvic floor dysfunctions include urinary incontinence, pelvic organ prolapsed and anal incontinence. One in ten women will be subjected to surgery for pelvic floor dysfunction during their lifetime. In addition, between 30% and 50% will have a recurrence of these interventions. Motherhood is a factor that contributes significantly to the submission of pelvic dysfunctions. There is still no proven evidence that vaginal delivery is an absolutely crucial factor for the presence of pelvic floor dysfunction. There is extensive research on pregnancy and child birth and their effects on the pelvic floor and if some of the obstetric action scan be modified in order to protect it from potential damage.

  8. Radiographic survey of perlite workers.

    Cooper, W C

    1975-05-01

    Chest roentgenograms of 240 perlite workers employed for 1 to 23 years in the industry, showed no evidence of pneumoconiosis associated with perlite exposures. One individual, found to have simple pneumoconiosis, and one found to have complicated pneumoconiosis, had formerly been diatomaceous earth workers. Since only 28 of the men had been in the industry over 15 years and only seven for 20 years or more, continued surveillance is essential to make sure that there are no effects with more prolonged exposures. Studies of pulmonary function of the individuals who have had relatively long exposures are needed to supplement radiographic evidence.

    1986-09-01

    Hirschprung disease is usually diagnosed in infancy. Occasionally patients reach adulthood without diagnosis or treatment. Four cases of adult Hirschprung disease are described. The principal radiographic findings are a markedly dilated, feces-filled colon above the zone of transition; a narrowed rectum; a cone- or funnel-shaped zone of transition; and a mosaic colonic pattern caused by collapsed redundant mucosa after colonic cleansing. In an adult, identification on a barium enema examination of an abrupt, smooth transition zone in the rectum with proximal colonic dilatation, in conjunction with an appropriate clinical history, should suggest the diagnosis of adult Hirschprung disease.

    Allergy to radiographic contrast media Hypersensitivity reactions to radio-contrast media are common in the daily practice. These products are responsible for immediate ( 1 hour after administration) hypersensitivity reactions. A diagnostic work-up by an allergologist with skin tests and in some cases provocation tests is of value in reducing the risk of recurrent hypersensitivity reactions to iodinated contrast media. A careful selection of the patients is required because the incidence of breakthrough reactions is still concerning, even with proper premedication. Practical recommendations are presented in this article. For gadolinium-based contrast agents, data in the literature is not sufficient for suggesting guidelines. PMID:23667970

  11. Retroperitoneal and pelvic hemangiopericytomas: A clinical, radiologic, pathologic correlative study

    International Nuclear Information System (INIS)

    The hemangiopericytoma (HP) is an aggressive neoplasm consisting of proliferation of endothelial-lined capillaries with intact reticulum sheaths surrounded by the pericyte. Approximately a fifth of these lesions occur in the retroperitoneum. This is the first large clinical, radiologic, pathologic study of retroperitoneal HP (17 cases). Significant clinical findings included a palpable mass (64%) and hypoglycemia in one. Approximately 40% were located in the true anatomic pelvis or near the cecum along the pelvic psoas muscle. Radiographically, a mass may be seen on plain film, IVP, or barium studies which might displace, compress, or rarely invade an adjacent organ. Most significant was the angiographic findings of an extremely vascular tumor with extensive collateralization, hypertrophy of vessels, and venous engorgement. On CT, HP appeared as a large, bulky well-defined enhancing tumor occasionally with areas of low density in a swirled or marbled pattern. Although by no means diagnostic, HP can be considered when a hypervascular retroperitoneal tumor is encountered on angiography or a large, enhancing mass with several low-density areas is recognized on CT

    Full Text Available OBJECTIVE: To ascertain the geometry of the femur in the Brazilian population by means of a radiographic study and to correlate the values with regard to sex and right/left side.METHODS: Five hundred anteroposterior radiographs of the pelvis of skeletally mature patients (250 of each sex who did not present any osteoarthrosis, fractures or tumoral or infectious lesions were analyzed. The length and width of the femoral neck, length of the femoral axis, neck-shaft angle and femoral offset were measured.RESULTS: The following means were observed: 36.54 mm for the length of the femoral neck; 37.48 mm for the width of the femoral neck; 108.42 mm for the length of the femoral axis; 130.47° for the neck-shaft angle; and 44.4 mm for the femoral offset.CONCLUSION: The mean values for the main measurements on the proximal femur in Brazilians differed from those of previous studies. It could also be shown that there was a statistically significant mean difference between men and women for all the variables, both on the left and on the right side, and that the men had greater means than the women.

    The present study aimed to diagnose complete rupture (CR) and longitudinal rupture (LR) of the posterior tibial tendon (PTT) from the magnetic resonance imaging findings in patients with PTT dysfunction and to analyze and compare the radiographs from each group to identify radiographic indicators related to the progression of PTT injury that would allow the radiographic diagnosis of CR. We evaluated 32 feet in 27 patients with PTT dysfunction (mean age 66.5, range 49 to 82, years). Radiographs were used to acquire weightbearing anteroposterior images of the foot, which were used to measure the talonavicular coverage angle. Lateral images of the foot were also acquired with the patients in the standing position. These were used to measure the lateral talometatarsal angle, calcaneal pitch angle, and medial cuneiform-fifth metatarsal height. From the axial MRI findings, the patients were divided into a CR group and an LR group, and the radiographic attributes of the CR group were analyzed. Of the 32 feet in 27 patients, 12 feet (37.5%) in 11 patients displayed CR and 20 feet (62.5%) in 18 patients displayed LR. The talonavicular coverage angle was 48.3° ± 17.3° in the CR group and 33.6° ± 13.6° in the LR group (p = .012), and the talometatarsal angle was -28.8° ± 22.5° in the CR group and -25.4° ± 14.4° in the LR group (p = .596). The calcaneal pitch angle was 10.4° ± 6.7° in the CR group and 10.2° ± 8.0° in the LR group (p = .935). Finally, the medial cuneiform-fifth metatarsal height was -4.2 ± 7.1 mm in the CR group and 2.1 ± 4.7 mm in the LR group (p = .005). When a medial cuneiform-fifth metatarsal height of ≤0 mm or talonavicular coverage angle of ≥50° was used as the diagnostic criterion for CR on weightbearing radiographs, the sensitivity was 71.4%, specificity 88.9%, and diagnostic accuracy 81.3%; hence, we believe these to be satisfactory diagnostic criteria for CR.

    Radiographs are commonly used to assess the fit of implant components, but there is no clear agreement on the amount of misfit that can be detected by this method. This study investigated the effect of gap size and the relative angle at which a radiograph was taken on the detection of component misfit. Different types of implant connections (internal or external) and radiographic modalities (film or digital) were assessed.

    International Nuclear Information System (INIS)

    It is generally accepted that scattered radiation degrades the quality of the radiographic image. When this problem occurs, a radiographic grid may be applied which necessitates an increase in exposure. Investigations are reported in the following areas: reasons for the introduction of a radiographic grid; the ratio between kilovoltage and grid ratio; techniques resulting in higher contrast and resolution at low patient dose and the abuse of grids

    Total elbow arthroplasty (TEA) is becoming a popular alternative to arthrodesis for patients with end-stage elbow arthrosis and comminuted distal humeral fractures. Prior outcome studies have primarily focused on surgical findings. Our purpose is to determine the radiographic outcome of TEA and to correlate with clinical symptoms such as pain. This is an IRB-approved retrospective review from 2005 to 2015 of all patients with semiconstrained TEA. All available elbow radiographs and clinical data were reviewed. Data analysis included descriptive statistics and Kaplan-Meier survival curves for radiographic and clinical survival. A total of 104 total elbow arthroplasties in 102 patients were reviewed; 75 % were in women and the mean patient age was 63.1 years. Mean radiographic follow-up was 826 days with average of four radiographs per patient. Seventy TEAs (67 %) developed radiographic complications, including heterotopic ossification (48 %), perihardware lucency (27 %), periprosthetic fracture (23 %), hardware subluxation/dislocation (7 %), polyethylene wear (3 %), and hardware fracture/dislodgement (3 %); 56 patients (55 %) developed symptoms of elbow pain or instability and 30 patients (30 %) underwent at least one reoperation. In patients with radiographic complications, 66 % developed elbow pain, compared to 19 % of patients with no radiologic complications (p = 0.001). Of the patients with radiographic complications, 39 % had at least one additional surgery compared to 0 % of patients without radiographic complications (p = 0.056). Radiographic complications are common in patients after total elbow arthroplasty. There is a strong positive association between post-operative radiographic findings and clinical outcome. Knowledge of common postoperative radiographic findings is important for the practicing radiologist. (orig.)

  19. Quality Assurance of Multifractionated Pelvic Interstitial Brachytherapy for Postoperative Recurrences of Cervical Cancers: A Prospective Study

    International Nuclear Information System (INIS)

    Purpose: To evaluate three-dimensional needle displacements during multifractionated interstitial brachytherapy (BT) for cervical cancers. Methods and Materials: Patients scheduled to undergo pelvic interstitial BT for postoperative and or postradiation vault recurrences were included from November 2009 to December 2010. All procedures were performed under spinal anesthesia. Postprocedure BT planning CT scans were obtained with patients in supine position with arms on the chest (interslice thickness of 3 mm). Thereafter, verification CT was repeated at every alternate fraction. Needle displacements were measured in reference to a relocatable bony point. The mean cranial, caudal, anteroposterior, and mediolateral displacements were recorded. Statistical significance of mean interfraction displacements was evaluated with Wilcoxon Test. Results: Twenty patients were included. Seventeen received boost BT (20 Gy/5 fractions/3 days) after external radiation, three received radical BT alone (36 Gy/9 fractions/5–8 days). An average of three scans (range, 2–3) were available per patient, and 357 needle displacements were analyzed. For the entire study cohort, the average of mean needle displacement was 2.5 mm (range, 0–7.4), 17.4 mm (range, 0–27.9), 1.7 mm (range, 0–6.7), 2.1 mm (range, 0–9.5), 1.7 mm (range, 0–9.3), and 0.6 mm (range, 0–7.8) in cranial, caudal, anterior, posterior, right, and left directions, respectively. The mean displacement in the caudal direction was higher between Days 1 and 2 than that between Days 2 and 3 (13.4 mm vs. 3.8 mm; p = 0.01). The average caudal displacements were no different between reirradiation and boost cohort (15.2 vs. 17.8 mm). Conclusions: Clinically significant caudal displacements occur during multifractionated pelvic brachytherapy. Optimal margins need to be incorporated while preplanning brachytherapy to account for interfraction displacements.

    The radiographic testing (RT) is a non-destructive testing (NDT) method capable of finding volumetric and open planar defects depending on their orientation. The radiographic contrast is higher for larger penetrated length of the defect in a component. Even though, the detectability of defects does not only depend on the contrast, but also on the noise, the defect area and the geometry of the defect. The currently applied Probability of Detection (POD) approach uses a detection threshold that is only based on a constant noise level or on a constant contrast threshold. This does not reflect accurately the results of evaluations by human observers. A new approach is introduced, using the widely applied POD evaluation and additionally a detection threshold depending on the lateral area and shape of the indication. This work shows the process of calculating the POD curves with simulated data by the modeling software aRTist and with artificial reference data of different defect types, such as ASTM E 476 EPS plates, flat bottom holes and notches. Additional experiments with different operators confirm that the depth of a defect, the lateral area and shape of its indication contribute with different weight to the detectability of the defect if evaluated by human operators on monitors.

  1. Gastric tumors on chest radiographs

    International Nuclear Information System (INIS)

    Gastric neoplasms of three patients protruded into their gas-containing fornices and were first visualized on plain chest radiographs. Endoscopy and/or surgery confirmed these to be a polyp, a leiomyoma, and an adenocarcinoma. The polyp, 1.3 cm in diameter, was the smallest of these three, but smaller lesions may be detectable under suitable conditions. Adequate technique and positioning, sufficiently large lesions in the upper portion of the stomach, a central beam tangential to the tumor, sufficient gas in the stomach, and careful scrutiny by the observer are required. Lesions may be more readily visualized during chest radiography when oral sodium bicarbonate is used to distend the stomach. In chest radiography, exposure limited to the lung fields has been advocated for economy and dose reduction. However, too small an exposure field may result in loss of information potentially beneficial to the patient. Using the smaller of two popular film sizes (35 x 43 cm and 35 x 35 cm), the saving in surface and bone marrow doses is negligible, and the saving in gonad dose may be nil over that when shielding is used. The interest of the observer may be absorbed by a concomitant cardiac or pulmonary lesion. Careful scrutiny of the entire radiograph is therefore essential. (author)

  2. Stepped scanner radiographic imaging system

    International Nuclear Information System (INIS)

    The imaging system includes a radiographic camera, a bed for supporting a subject in view of the camera, and a display system. The camera provides X and Y coordinate signals of each radiographic event. The position of the bed relative to the camera is altered sequentially by drive means, between each of a sequence of images provided by the camera. The sequentially occurring images are presented on the display system, each image being positioned on the display in correspondence with the location of the bed relative to the camera. The coordinates of each image point presented on the display is equal to the sum of the respective X and Y coordinate signals from the camera with X and Y coordinate signals provided by a timer which controls the drive means and defines the location of the bed relative to the camera. The camera is electronically decoupled from the display by a gate during movement of the bed relative to the camera from one location to the next location to prevent any smearing effect within the composite image presented on the display.

    Disorders of the posterior pelvic floor are relatively common. The role of imaging in this field is increasing, especially in constipation, prolapse and anal incontinence, and currently imaging is an integral part of the investigation of these pelvic floor disorders. Evacuation proctography provides both structural and functional information for rectal voiding and prolapse. Dynamic MRI may be a valuable alternative as the pelvic floor muscles are visualised, and it is currently under evaluation. Endoluminal imaging is important in the management of anal incontinence. Both endosonography and endoanal MRI can be used for detection of anal sphincter defects. Endoanal MRI has the advantage of simultaneously evaluating external sphincter atrophy, which is an important predictive factor for the outcome of sphincter repair. Many aspects of constipation and prolapse remain incompletely understood and treatment is partly empirical; however, imaging has a central role in management to place patients into treatment-defined groups.

  11. Functional imaging of the pelvic floor

    Energy Technology Data Exchange (ETDEWEB)

    Lienemann, Andreas E-mail: andreaslienemann@web.de; Fischer, Tanja

    2003-08-01

    Introduction/Objective: Pelvic floor dysfunction and associated pelvic organ prolapse represent a major problem in our present-day society, mostly afflicting parous women. Magnetic resonance imaging (MRI) is assuming an increasingly important role in the more accurate delineation of the extent of the problem. This article briefly reviews one of the main radiological methods for the dynamic evaluation of the pelvic floor: functional cine MRI. Methods and Material: Out of the literature the smallest common denominator for functional cine MRI can be defined as follows: high field system; patient either in supine or sitting position; fast gradient echo sequence; midsagittal slice orientation; either a stack of slices or repeated measurements at the same slice position with the patient at rest or straining; image analysis using the pubococcygeal reference line. Results: All except two publications stress the usefulness of functional cine MRI in the evaluation of patients with organ descent and prolapse. This well accepted method allows for the visualization of all relevant structures in the anterior, middle and posterior compartment. It is especially useful in the detection of enteroceles, and provides a reliable postoperative follow-up tool. Isolated urinary or stool incontinence are not an indication for functional cine MRI, as is the case in patients with equivocal clinical findings. To date it does not allow for real 3D imaging of the pelvic floor or sufficient determination of fascial defects. Discussion: Functional cine MRI of the pelvic floor is a promising new imaging method for the detection of organ descent and prolapse in patients with equivocal clinical findings. The combination of function and morphology allows for an innovative view of the pelvic floor, and thus adds to our understanding of the various interactions of the structures.

    Fractures of the pelvic ring are comparatively rare with an incidence of 2-8 % of all fractures depending on the study in question. The severity of pelvic ring fractures can be very different ranging from simple and mostly "harmless" type A fractures up to life-threatening complex type C fractures. Although it was previously postulated that high-energy trauma was necessary to induce a pelvic ring fracture, over the past decades it became more and more evident, not least from data in the pelvic trauma registry of the German Society for Trauma Surgery (DGU), that low-energy minor trauma can also cause pelvic ring fractures of osteoporotic bone and in a rapidly increasing population of geriatric patients insufficiency fractures of the pelvic ring are nowadays observed with no preceding trauma.Even in large trauma centers the number of patients with pelvic ring fractures is mostly insufficient to perform valid and sufficiently powerful monocentric studies on epidemiological, diagnostic or therapeutic issues. For this reason, in 1991 the first and still the only registry worldwide for the documentation and evaluation of pelvic ring fractures was introduced by the Working Group Pelvis (AG Becken) of the DGU. Originally, the main objectives of the documentation were epidemiological and diagnostic issues; however, in the course of time it developed into an increasingly expanding dataset with comprehensive parameters on injury patterns, operative and conservative therapy regimens and short-term and long-term outcome of patients. Originally starting with 10 institutions, in the meantime more than 30 hospitals in Germany and other European countries participate in the documentation of data. In the third phase of the registry alone, which was started in 2004, data from approximately 15,000 patients with pelvic ring and acetabular fractures were documented. In addition to the scientific impact of the pelvic trauma registry, which is reflected in the numerous national and

    Full Text Available The Wnt/β-catenin or canonical Wnt signaling pathway plays fundamental roles in early development and in maintaining adult tissue homeostasis. R-spondin 3 (Rspo3 is a secreted protein that has been implicated in activating the Wnt/β-catenin signaling in amphibians and mammals. Here we report that zebrafish Rspo3 plays a negative role in regulating the zygotic Wnt/β-catenin signaling. Zebrafish Rspo3 has a unique domain structure. It contains a third furin-like (FU3 domain. This FU3 is present in other four ray-finned fish species studied but not in elephant shark. In zebrafish, rspo3 mRNA is maternally deposited and has a ubiquitous expression in early embryonic stages. After 12 hpf, its expression becomes tissue-specific. Forced expression of rspo3 promotes dorsoanterior patterning and increases the expression of dorsal and anterior marker genes. Knockdown of rspo3 increases ventral-posterior development and stimulates ventral and posterior marker genes expression. Forced expression of rspo3 abolishes exogenous Wnt3a action and reduces the endogenous Wnt signaling activity. Knockdown of rspo3 results in increased Wnt/β-catenin signaling activity. Further analyses indicate that Rspo3 does not promote maternal Wnt signaling. Human RSPO3 has similar action when tested in zebrafish embryos. These results suggest that Rspo3 regulates dorsoventral and anteroposterior patterning by negatively regulating the zygotic Wnt/β-catenin signaling in zebrafish embryos.

    Full Text Available Total pelvic exenteration (PE is a radical operation, involving en bloc resection of pelvic organs, including reproductive structures, bladder, and rectosigmoid. In gynecologic oncology, it is most commonly indicated for the treatment of advanced primary or locally recurrent cancer. Careful patient selection and counseling are of paramount importance when considering someone for PE. Part of the evaluation process includes comprehensive assessment to exclude unresectable or metastatic disease. PE can be curative for carefully selected patients with gynecologic cancers. Major complications can be seen in as many as 50% of patients undergoing PE, underscoring the need to carefully discuss risks and benefits of this procedure with patients considering exenterative surgery.

    Acute pelvic pain in women is a routine situation in any emergency unit. The radiologist should know how to explore the patient with regards to the history and clinical findings. Ultrasonography is the primary and sometimes the only necessary imaging tool in the assessment of acute pelvic pain in women. MRI is the preferred technique in pregnant or young women. CT is more valuable for assessing nongynecologic disorders or post-partum and post-operative infections. This article reviews the contribution of each imaging technique in this clinical situation. Emphasis is put on the importance of age and clinical findings in the diagnostic strategy. PMID:18288036

    The objectives of this work were to retrospectively describe the radiographic assessment of INBONE total ankle arthroplasty in 30 patients using validated linear and angular measurements and to correlate these findings with the final surgical outcome over a 2-year follow-up period. Thirty consecutive patients (21 females, nine males; mean age, 64.8 years) underwent INBONE total ankle arthroplasty during 2007-2011. After IRB approval, a retrospective pre- and post-operative radiographic analysis was performed using validated linear and angular measurements. The pre- and post-operative assessment included the tibial angle, talar angle, tibial slope, and coronal deformity. Post-operative measurements also included the talocalcaneal angle, joint space height, talar height, lateral tibial component angle, lateral talar component angle, and anteroposterior tibial component angle. The post-operative bone loss, subluxation, positioning, and subsidence were also assessed. Statistical analysis was performed using two-sample t test and Fisher's exact test. Out of 30 patients, 23 had a successful clinical outcome with intact prosthesis at a 2-year follow-up. The only variables with significant correlation (p < 0.05) to the post-surgical outcome were the lateral talar component angle (p = 0.002) and the mean difference between pre- and post-operative tibial slope (p = 0.001). The coronal deformity had significant mean difference between pre- and post-operative values (p < 0.001); however, it lacked a significant correlation to the final surgical outcome. None of the categorical variables had a significant correlation with post-surgical outcome. In our retrospective study, only the lateral talar component angle and the mean difference between the pre- and post-operative tibial slope had significant correlation with post-surgical outcome in INBONE ankle arthroplasty. These measurements may be helpful in radiographic assessment of the INBONE ankle arthroplasty. (orig.)

    Objective: To describe radiographic features of gout that may mimic infection. Design and patients: We report five patients with acute bacterial gout who presented with clinical as well as radiological findings mimicking acute bacterial septic arthritis or osteomyelitis. Three patients had delay in the appropriate treatment with the final diagnosis being established after needle aspiration and identification of urate crystals under polarized light microscopy. Two patients underwent digit amputation for not responding to antibiotic treatment and had histological findings confirming the diagnosis of gout. Conclusion: It is important for the radiologist to be aware of the radiological manifestations of acute gout that can resemble infection in order to avoid inappropriate diagnosis and delay in adequate treatment. The definitive diagnosis should rely on needle aspiration and a specific search for urate crystals. (orig.)

    The author studied clinically and radiologically 55 cases which had been diagnosed as odontoma in SNUDH. The obtained results were as follows: 1. In sex distribution, there was no prevalence in both sexes. And the incidence was the highest in the 2nd decade (16 patient, 29%). 2. There were 42 cases of compound odontoma (76%) and 13 cases of complex odontoma (24%). In most cases, compound odontoma was located at the anterior portion (34 cases, 81%) and complex odontoma at the posterior portions (9 cases, 69%). 3. There was no apparent clinical symptom in compound odontoma (83%), but in complex odontoma, 80% of cases show swelling. 4. The adjacent root resorption was not observed in any case. 5. Five cases radiographically diagnosed as cystic odontoma were not confirmed histopathologically.

  1. Visual perception and radiographic interpretation

    International Nuclear Information System (INIS)

    Although interpretation errors are common in radiology, their causes are still debated. Perceptual mechanisms appear to be responsible for a large proportion of mistakes made by both neophytes and trained radiologists. Erroneous perception of familiar contours can be triggered by unrelated opacities. Conversely, visual information cannot induce a specific perception if the observer is not familiar with the concept represented or its radiographicappearance. Additionally, the area of acute vision is smaller than is commonly recognized. Other factors, such as the attitude, beliefs,.: preconceptions, and expectations of the viewer, can affect what he or she ''sees'' whenviewing any object, including a radiograph. Familiarity with perceptual mechanisms and the limitations of the visual system as well as multiple readings may be necessary to reduce interpretation errors

  2. Consultant breast radiographers: Where are we now?

    International Nuclear Information System (INIS)

    Introduction: The aim of this study is to: • Evaluate the current role of the consultant breast radiographer. • Compare current practice with the four key components for consultant practice. • Gauge the support of radiologist colleagues. • Determine the other professional commitments involved with the role. This study could be the precursor for a macro study of all consultant radiographer practice in other specialities. Methodology: Methodology used was a comparative ethnographic study. Questionnaires to the 24 consultant breast radiographers currently in post, and consultant breast radiologists, who work with them, were conducted. Data collection was a qualitative thematic approach. Conclusion: Consultant breast radiographers provide high quality care to patients through excellent clinical practice, leadership and good communication. However, this study shows hospital Trusts emphasis for non medical consultants is for clinical practice first. Some radiologists are still a barrier to progression for consultant breast radiographers, and radiologists have a big influence in recruitment decisions. Consultant breast radiographer posts are well established, their numbers are increasing through recognition of the role and of their abilities and performance. Consultant breast radiographers state that becoming a consultant is the major achievement of their career, proving the Society of Radiographers' vision of the four-tier career structure has been well received by the radiography profession

  6. Adult chest radiograph reporting by radiographers: Preliminary data from an in-house audit programme

    International Nuclear Information System (INIS)

    Aim: To examine the adult chest radiograph (CXR) reporting performance of a reporting radiographer in clinical practice using different audit systems; single radiologist and two radiologists, with clinical review of discordant cases. Materials and methods: 100 chest radiographs (CXRs) were drawn randomly from a consecutive series of 4800 CXRs which had been reported during a nine month period at a district general hospital by a radiographer after two years of training. Diagnostic outcomes were normal or abnormal, and agreement with the reporting radiographer or not. There was 50% duplication of CXRs reported between three radiologists. Concordance rates were determined for the radiographer-radiologist and inter-radiologist interpretations. Independent clinical review of discordant cases was performed to establish the final diagnosis. Results: Ninety-nine cases were reviewed, with 40 cases deemed abnormal by at least one radiologist. Consensus was found with the radiographers report in 59 normal and 33 abnormal CXRs reviewed by two radiologists (96.7% and 86.8% respectively). Seven CXR reports were discrepant with clinical review: mediastinal lymphadenopathy was missed by both radiologist and radiographer; linear atelectasis was reported by two radiologists but not the radiographer. Three cases were over-interpreted and on two occasions at least one radiologist agreed with the radiographer. There was very high concordance between the radiographer and each radiologist, 96%, 96% and 92% respectively. Conclusions: This study suggested that regular audit, which incorporates case note review and discrepant reporting within a multidisciplinary setting, should contribute to safe practice

    We present the case of a former user of an intrauterine contraceptive device (IUD) for 10 years, diagnosed with a bulky, fixed pelvic tumor involving the internal genital organs and the recto sigmoid, causing luminal narrowing of the rectum, interpreted as locally advanced pelvic malignancy, probably of genital origin. Intraoperatively, a high index of suspicion made us collect a sample from the fibrous wall of the tumor mass, large Actinomyces colonies were thus identified. Surgery consisted in debridement, removal of a small amount of pus and appendectomy, thus avoiding a mutilating and useless surgery. Specific antibiotic therapy was administered for 3 months, with favorable postoperative and long-term outcomes. Pelvic actinomycosis should always be considered in the differential diagnosis of pelvic tumors in women using an IUD. The association of long-term antibiotic treatment is essential to eradicate the infection and prevent relapses. PMID:27483724

    A retrospective study. To summarize and describe the radiographic parameters of adult degenerative scoliosis (ADS) and explore the radiological parameters which are significantly different in sagittal balanced and imbalanced ADS patients. ADS is the most common type of adult spinal deformity. However, no comprehensive description of radiographic parameters in ADS patients has been made, and few studies have been performed to explore which radiological parameters are significantly different between sagittal balanced and imbalanced ADS patients. Medical records of ADS patients in our outpatient clinic from January 2012 to January 2014 were reviewed. Demographic data including age and sex, and radiographic data including the coronal Cobb angle, location of apical vertebra/disc, convexity of the curve, degree of apical vertebra rotation, curve segments, thoracic kyphosis (TK), lumbar lordosis (LL), thoracolumbar kyphosis (TL), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), sagittal vertical axis (SVA), and PI minus LL (PI-LL) were reviewed to make comprehensive description of radiographic parameters of ADS. Furthermore, patients were divided into 2 groups according to whether the patients' sagittal plane was balanced: Group A (imbalanced, SVA > 5 cm) and Group B (balanced, SVA  ≤ 5 cm). Demographic and radiological parameters were compared between these 2 groups. A total of 99 patients were included in this study (Group A = 33 and Group B = 66; female = 83 and male = 16; sex ratio = 5:1). The median of age were 67 years (range: 41-92 years). The median of coronal Cobb angle and length of curve was 23 (range: 10-75°) and 5 segments (range: 3-7), respectively. The most common location of apical vertebra was at L2 to L3 (81%) and the median of degree of apical vertebra rotation was 2° (range: 1-3). Our study also showed significant correlations between coronal Cobb angle and curve segments (r = 0.23, P < 0.005) and degree of apical vertebra rotation (r

    Male genitalia evolve rapidly, probably as a result of sexual selection. Whether this pattern extends to the internal infrastructure that influences genital movements remains unknown. Cetaceans (whales and dolphins) offer a unique opportunity to test this hypothesis: since evolving from land-dwelling ancestors, they lost external hind limbs and evolved a highly reduced pelvis that seems to serve no other function except to anchor muscles that maneuver the penis. Here, we create a novel morphometric pipeline to analyze the size and shape evolution of pelvic bones from 130 individuals (29 species) in the context of inferred mating system. We present two main findings: (1) males from species with relatively intense sexual selection (inferred by relative testes size) tend to evolve larger penises and pelvic bones compared to their body length, and (2) pelvic bone shape has diverged more in species pairs that have diverged in inferred mating system. Neither pattern was observed in the anterior-most pair of vertebral ribs, which served as a negative control. This study provides evidence that sexual selection can affect internal anatomy that controls male genitalia. These important functions may explain why cetacean pelvic bones have not been lost through evolutionary time.

    To determine the frequency of disease, and to evaluate the methods used for lumbar spine radiography in Korea. Sixty university and training hospitals were randomly selected and asked to describe the projections, film size and radiographic techniques employed for routine radiography in patients with suspected disease of the lumbar spine. Plain radiographs of 1215 patients, taken using 14x17 inch film and depicting both hip joints and the lumbar region, were analysed between March 1999 and February 2000. In 15 patients (1.2%), the radiographs revealed hip or pelvic lesion, confirmed as follows: avascular necrosis of the femoral head (n=11, with bilateral lesion in four cases); sustained ankylosing spondylitis (n=2); acetabular dysplasia (n=1); and insufficiency fracture of the pubic rami secondary to osteoporosis (n=1). In 11 or the 20 hospitals which responded, 14{sup x}17{sup f}ilm was being used for lumbar radiography, while in the other nine, film size was smaller. Plain radiography of the lumbar spine including both hip joints, may be a useful way to simultaneously evaluate lesions not only of the lumbar spine but also of the hip and/or pelvis.

    Full Text Available AbstractBackground: Endometriosis is a common gynecological problem associated with chronic pelvic pain. Objective: To evaluate the effectiveness of current hormonal treatments of endometriosis associated pain.Materials and Methods: Randomized Controlled studies identified from databases of Medline and Cochrane Systemic Review groups were pooled. 7 RCTs were recruited for evaluation in this review. Data from these studies were pooled and meta-analysis was performed in three comparison groups: 1 Progestogen versus GnRHa; 2 Implanon versus Progestogen (injection; 3 Combined oral contraceptive pills versus placebo and progestogen. Response to treatment was measured as a reduction in pain score. Pain improvement was defined as improvement ≥1 at the end of treatment. Results: There was no significant difference between treatment groups of progestogen and GnRHa (RR: 0.036; CI:-0.030-0.102 for relieving endometriosis associated pelvic pain. Long acting progestogen (Implanon and Mirena are not inferior to GnRHa and depot medroxy progesterone acetate (DMPA (RR: 0.006; CI:-0.142-0.162. Combined oral contraceptive pills demonstrated effective treatment of relieving endometriosis associated pelvic pain when compared with placebo groups (RR:0.321CI-0.066-0.707. Progestogen was more effective than combined oral contraceptive pills in controlling dysmenorrhea (RR:-0.160; CI:-0.386-0.066, however, progestogen is associated with more side effects like spotting and bloating than the combined contraceptive pills. Conclusion: Combined oral contraceptive pills (COCP, GnRHa and progestogens are equally effective in relieving endometriosis associated pelvic pain. COCP and progestogens are relatively cheap and more suitable for long-term use as compared to GnRHa. Long-term RCT of medicated contraceptive devices like Mirena and Implanon are required to evaluate their long-term effects on relieving the endometriosis associated pelvic pain

  15. Sox31 is involved in central nervous system anteroposterior regionalization through regulating the organizer activity in zebrafish

    Sox superfamily proteins are DNA-binding transcriptional factors that contain highly conserved high-mobility group (HMG) box and take part in various development process.Sox31 is a maternal factor supplied in the oocyte and starts its zygotic expression during mid-blastula transition (MBT)From gastrulation stage, it mainly resides in neural tissue.Ectopically expression of Sox31 mRNA leads to cyclopia fusion eyes or totally loss of anterior head structure, in accompany with severe notochord defects. Molecular markers indicate that forebrain tissue reduces sharply while the posterior neural tissue expands anteriorly. In addition organizer specification is also suppressed. Oppositely, an antisense morpholino designed functionally knockdown Sox31 causes typically dorsalized phenotype and reversed central nervous system (CNS) anteroposterior (AP) patterning. Gain of function with chimeric construct, where Sox31 HMG DNA binding domain is fused to a transcription activation domain (VP16) or transcnption suppression domain (EnR), suggests that Sox31 acts as a transcriptional suppressor in vivo. The expression of Bozozok (Dharma), a direct target gene of pre-MBT Wnt/p-catenin signal is suppressed by Sox31 Thus, to unveil the relationship between Sox31 and β-catenin-related transcriptional activity, we designed Top/Fop luciferase assay in HEK293T cells, and found that Sox31 could indeed suppress Tcf/Lef-dependent transcriptional activity without influencing the stability of β-catenin.Moreover, post-MBT Wnt signal was reduced in Sox31 morphants corresponding to the suppressed hindbrain structure, while phenotypic defects caused by excessive Sox31 could be rescued by Wnt antagonist dkkl. Taken together, Sox31 functions as an essential CNS AP patterning determinant and coordinates the CNS AP patterning process with organizer specification.

  16. Gamma radiographic exposure time indicator

    International Nuclear Information System (INIS)

    In industrial radiography, with the proper selection of source and film, the radiographic quality depends very much on the exposure time, which in turn depends upon the source strength and the source to film distance. Conventional methods to arrive at correct exposure time involve time consuming calculations and in these methods the knowledge of the above mentioned parameters is imperative. An instrument to determine the required exposure time has been developed which indicates exposure times in about 30 secs. This covers two commonly used gamma radiography sources, viz., 192Ir and 60Co and six commonly used radiography films of different speeds. Knowledge of source strength and source to film distance is not required with the use of this instrument. With a knowledge of the total exposure required by the film to give the required sensitivity and by the measurement of radiation level at the film location, the correct exposure time is determined. The radiation level is measured by placing a GM counter behind the radiographic specimen at the film location. To match the responses of the film and the GM counter, the counter is incorporated in a suitably designed probe. In this instruments, an integrator to integrate the GM-pulses and a constant current integrator (timer) are started simultaneously. The voltage at the GM-pulse integrator is compared with a preselected voltage, (selected on the basis of film type, source, source strength and order of object thickness) by a comparator. The comparator is so adjusted that when the GM-pulse integrator voltage exceeds the preselected voltage, it switches its state and stops the integration of constant current. The constant current integrator output which is proportional to the time taken for the GM-pulse integrator to reach the preselected voltage, is read on a meter graduated in terms of exposure time. The instrument can measure exposure times from 5 minutes to 10 hours read in two ranges, the range-changing being automatic

    Purpose: It has been hypothesized that photographs can facilitate the interpretation of the radiographic characteristics of trabecular bone. The reliability of these photographic and radiographic approaches has been determined, as have various agreements between the two approaches and their correlations with biomechanical characteristics. Material and Methods: Fourteen vertebral bodies were obtained at autopsy from 6 women and 8 men aged 22-76 years. Photographs (n=28) and radiographs (n=28) were taken of midsagittal slices from the third lumbar vertebra. The radiographs and photographs were digitized and the geometric properties of the trabecular architecture were then determined with a digital images analysis technique. Information on the compressive strength and ash density of the vertebral body was also available. Results: The geometric properties of both radiographs and photographs could be measured with a high degree of reliability (Cronbach`s {alpha}>0.85). Agreement between the radiographic and photographic approaches was mediocre as only the radiographic measurements showed insignificant correlations (p<0.05) with the biomechanical characteristics. We suggest that optical phenomena may result in the significant correlations between the photographs and the biomechanical characteristics. Conclusion: For digital image processing, radiography offers a superior description of the architecture of trabecular bone to that offered by photography. (orig.)

    Introduction: Amongst the most frequently handled objects in the radiology department are radiographic markers. They are personal accessories used with every patient, and are kept in the radiographers pockets when not utilised. Upon enquiry it was discovered that many radiographers disregarded the potential of these accessories to become a vector for cross-contamination thus never or rarely clean them. The aims of this study were therefore to identify if radiographic markers are a reservoir for bacteria and to establish an effective cleaning method for decontaminating them. Methodology: 25 radiographers/student radiographers were selected for this study. Swabbing of their markers prior and post cleaning took place. The microbiology laboratory subsequently analyzed the results by quantifying and identifying the bacteria present. The participants also completed a closed questionnaire regarding their markers (e.g. frequency of cleaning and type of marker) to help specify the results gained from the swabbing procedure. Results: From the sample swabbed, 92% were contaminated with various organisms including Staphylococcus and Bacillus species, the amount of bacteria present ranged from 0 to >50 CFU. There were no significant differences between disinfectant wipes and alcohol gel in decontaminating the markers. Both successfully reduced their bacterial load, with 80% of the markers post cleaning having 0 CFU. Conclusion: The results indicated that radiographic markers can become highly contaminated with various organisms thus serve as a reservoir for bacteria. In addition, the markers need to be cleaned on a regular basis, with either disinfectant wipes or alcohol gel to reduce their bacterial load.

    Guidelines allow retakes of dental radiographs of up to 10%. In the general practice the percentage of retakes is considerably higher. In intraoral radiography film positioning and faults in directing the collimator are the most common reasons for retakes. The use of film holders and correctly aiming the collimator decrease the risk of failure. In panoramic radiography the positioning of the patient in the x-ray machine and the palatoglossal air space are the main causes of failure of radiographs. A systematic approach, a thorough check of the radiation area for artefacts and the use of the available laser lines decrease the risk of a diagnostically unacceptable radiograph. PMID:26210220

  1. Consultant radiographer leadership - A discussion

    International Nuclear Information System (INIS)

    Effective leadership can be defined in many ways and is an essential element of successful organisations; poor leadership can result in problems such as low staff morale, high staff turnover and reduced productivity. Effective leadership behaviours are well documented in the literature and various leadership models have been proposed that illustrate these behaviours. This discussion paper does not focus on any particular model. Instead it considers the 'Leadership Qualities Framework' which was developed specifically for use within the UK National Health Service. This framework draws upon a range of leadership models and as such it gives a broad indication of leadership behaviours. The framework comprises three components - 'personal qualities', 'setting direction' and 'delivering the service'. This paper commences with an argument as to why effective leadership is important in organisations generally, and specifically within healthcare organisations. Various examples of leadership are illustrated from within and outside the NHS in order to demonstrate effective leadership behaviours. The Leadership Qualities Framework is then examined, along with scenarios to illustrate effective leadership behaviours in context (i.e. within a healthcare organisation). Subsequent reflections on the scenarios aim to identify leadership behaviours that are explained within the framework. The final element of this paper draws on [limited] published evidence of where consultant radiographers have demonstrated effective leadership behaviours. In this section the published evidence is examined and reflected upon. At the end of the article we indicate additional reading for those who wish to further develop their theoretical and practical leadership skills

    Morphological imaging, based on the use of various techniques including ultrasound, X-ray computed tomography (CT), and magnetic resonance imaging (MRI), plays an important role in the characterization, diagnosis and follow-up of patients with Human Immunodeficiency Virus (HIV) infection and Acquired Immunodeficiency Syndrome (AIDS). While the presence of thoracic infections, the most frequently observed illnesses in AIDS patients, can best be performed by using conventional chest films and CT, the assessment of cerebral involvement in AIDS patients - characterized by the presence of focal masses, demyelination, meningitis, and infarction - is best achieved using MRI. The work-up of patients with gastrointestinal symptoms should include the use of ultrasound for the evaluation of visceral involvement and lymphadenopathy, completed by CT to further characterize pathologic conditions in either the bowel or visceral organs. Ultrasound is the screening exam of choice in AIDS patients with suspected renal disease, but other methods may be necessary for the assessment of the complications due to pharmacological treatment. Musculoskeletal complications may require the combined use of all the above methods, since they may be caused by infections, tumors and rheumatologic illness. The use of the radiographic methods for the detection of the numerous forms of infections and malignancies in AIDS patients is described in detail for the various body districts.

  3. Pelvic interstitial brachytherapy - improving the therapeutic ratio with magnetic resonance imaging and optimization

    International Nuclear Information System (INIS)

    Introduction Interstitial brachytherapy in the pelvic region is often hampered by the radiation oncologist's inability to precisely differentiate tumor versus normal tissue during the planning and implantation procedures, often resulting in either excessive or incomplete coverage of tumor volume. The marked improvement in pelvic imaging seen with magnetic resonance, in conjunction with isodose optimization programs for remote-afterloading units, has created an opportunity to significantly improve the therapeutic ratio. Methods From 1992-1995, 23 interstitial perineal templates were performed in 22 patients with pelvic malignancies, using the pulsed low-dose-rate Selectron with dose optimization. MR imaging was performed immediately prior to the implant, with a MUPIT placed against the perineum and a vaginal obturator in place. These images were used for tumor volume measurements, determination of the number, depth and angle of needles required for the implant, and identification of position of normal tissues (rectum, small bowel, bladder) relative to the tumor. After implantation of stainless steel needles, orthogonal radiographs were obtained for isodose calculation, and planning carried out with isodose optimization. Patients were followed closely on a routine schedule, until time of last visit or until death. Every effort possible was made to assess local disease status at time of death. Results Sixteen patients with primary disease (14 cervix, 1 vulva, 1 vagina) and 6 with recurrent (2 with prior radiation) were implanted, all but 3 with curative intent. Nine patients with advanced cervix or vulvar cancer received concomitant chemotherapy (5FU + platinum or mitomycin-C) with the external beam therapy. At a median follow-up of 18.1 months for all cases, only three patients have failed locally for an actuarial local control of 85% at 1.5 years. Nine patients are alive and free of disease, 8 are alive with distant disease only (mean follow-up of 19.1 months), 2

    Full Text Available Abstract Introduction Pelvic actinomycosis constitutes 3% of all human actinomycosis infections. It is usually insidious, and is often mistaken for other conditions such as diverticulitis, abscesses, inflammatory bowel disease and malignant tumors, presenting a diagnostic challenge pre-operatively; it is identified post-operatively in most cases. Here we present a case that presented as pelvic malignancy and was diagnosed as pelvic actinomycosis post-operatively. Case presentation A 48-year-old Caucasian Turkish woman presented to our clinic with a three-month history of abdominal pain, weight loss and difficulty in defecation. She had used an intra-uterine device for 16 years, however it had recently been removed. The rectosigmoidoscopy revealed narrowing of the lumen at 12 cm due to a mass lesion either in the wall or due to an extrinsic lesion that prevented the passage of the endoscope. On examination, there was no gynecological pathology. Magnetic resonance imaging showed a mass, measuring 5.5 × 4 cm attached to the rectum posterior to the uterus. The ureter on that side was dilated. Surgically there was a pelvic mass adhered to the rectum and uterine adnexes, measuring 10 × 12 cm. It originated from uterine adnexes, particularly ones from the left side and formed a conglomerated mass with the uterus and nearby organs; the left ureter was also dilated due to the pelvic mass. Because of concomitant tubal abscess formation and difficulty in dissection planes, total abdominal hysterectomy and bilateral salphingo-oophorectomy was performed (our patient was 48 years old and had completed her childbearing period. The cytology revealed inflammatory cells with aggregates of Actinomyces. Penicillin therapy was given for six months without any complication. Conclusions Pelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intra-uterine devices, and who have a history of appendectomy, tonsillectomy

    Oral fluids are potential contaminants of radiographic processors. This investigation measured bacterial contamination in a radiographic processing room during times of high and low clinical activity and processing effects on five types of microorganisms. Cultures in the clinical setting, during high and low activity, were taken by brain-heart infusion agar plates placed near automatic processors. Site samples were taken of entrance, developer, fixer, water, and exit surfaces. Measurements of processing effects were accomplished by intentional contamination of films run in series through an automatic processor. Site samples were again taken of the processor. In the clinical setting colony-forming units increased with activity. Radiographic processing after intentional contamination decreased colony-forming units on films, but they increased for all processing solutions. Bacteria on radiographic film survived processing. Although processing procedures significantly reduce the number of bacteria on films, the potential for contamination and cross-contamination remains. PMID:2122350

  6. Radiographers and radiologists reporting plain radiograph requests from accident and emergency and general practice

    International Nuclear Information System (INIS)

    AIM: To assess selectively trained radiographers and consultant radiologists reporting plain radiographs for the Accident and Emergency Department (A and E) and general practitioners (GPs) within a typical hospital setting. METHODS: Two radiographers, a group of eight consultant radiologists, and a reference standard radiologist independently reported under controlled conditions a retrospectively selected, random, stratified sample of 400 A and E and 400 GP plain radiographs. An independent consultant radiologist judged whether the radiographer and radiologist reports agreed with the reference standard report. Clinicians then assessed whether radiographer and radiologist incorrect reports affected confidence in their diagnosis and treatment plans, and patient outcome. RESULTS: For A and E and GP plain radiographs, respectively, there was a 1% (95% confidence interval (CI) -2 to 5) and 4% (95% CI -1 to 8) difference in reporting accuracy between the two professional groups. For both A and E and GP cases there was an 8% difference in the clinicians' confidence in their diagnosis based on radiographer or radiologist incorrect reports. For A and E and GP cases, respectively, there was a 2% and 8% difference in the clinicians' confidence in their management plans based on radiographer or radiologist incorrect reports. For A and E and GP cases, respectively, there was a 1% and 11% difference in effect on patient outcome of radiographer or radiologist incorrect reports. CONCLUSION: There is the potential to extend the reporting role of selectively trained radiographers to include plain radiographs for all A and E and GP patients. Further research conducted during clinical practice at a number of sites is recommended

    The author studied, with emphasis on the various radiographic projections, the 99 cases of liver enlargement, which underwent the barium meal upper gastrointestinal examinations for the purpose of pursuit of significance of liver enlargement and, at the same time were confirmed by other clinical and pathological methods at Busan National University Hospital for about 2 years from November 1977 to September 1979. The following results were obtained: 1. The incidence of liver enlargement was 63.3% (62 cases) in the 5th decade, which was most prevalent, 18.2% (18 cases) in the 3rd decade, 15.2% (15 cases) in the group over 60, and 3.0% (3 cases) in the age group below 20. Male to female sex ratio was 2 : 1. 2. The causes of the liver enlargement confirmed by the final diagnosis are as follows: Primary hepatic cancer 39 cases (39.3%), liver cirrhosis 30 cases (30.3%), chronic hepatitis 12 cases (12.1%), cancer of the biliary tract 6 cases (6.1%), hepatic fluke 6 cases (6.1%), metastatic tumors 3 cases (3.0%), and hepatic congestion 3 cases (3.0%) 3. In the prone view, the displacement of the duodenal bulb appeared in 18 cases (18.2%). 4. In the routine radiographs, the displacement of the stomach to the left and the pressure indentation of the lesser curvature were noted in 69 cases (69.7%) out of 99 cases. 5.In the left lateral recumbent view, the pressure indentation of the anterior border of the gastric body was seen in 96 cases (97.0%) among the 99 cases, the straightening in 30 cases (27.3%), the marked depression in 30 cases (30.3%), the moderate in 27 cases (27.3%), the minimal in 9 cases (9.1%). 6. Comparing the incidences of the roentgen findings of the liver enlargement in the various projections respectively, the displacement of the duodenal bulb was noted in 18 cases (18.3%) in the prone position. The erect position revealed the displacement of the stomach to the left and the pressure indentation in 57 cases (57.6%), the prone position in 51 cases (51

    Bending, in addition to compression, is recognized to be a common loading pattern in long bones in animals. However, due to the technical difficulty of measuring bone deformation in humans, our current understanding of bone loading patterns in humans is very limited. In the present study, we hypothesized that bending and torsion are important loading regimes in the human tibia. In vivo tibia segment deformation in humans was assessed during walking and running utilizing a novel optical approach. Results suggest that the proximal tibia primarily bends to the posterior (bending angle: 0.15°-1.30°) and medial aspect (bending angle: 0.38°-0.90°) and that it twists externally (torsion angle: 0.67°-1.66°) in relation to the distal tibia during the stance phase of overground walking at a speed between 2.5 and 6.1 km/h. Peak posterior bending and peak torsion occurred during the first and second half of stance phase, respectively. The peak-to-peak antero-posterior (AP) bending angles increased linearly with vertical ground reaction force and speed. Similarly, peak-to-peak torsion angles increased with the vertical free moment in four of the five test subjects and with the speed in three of the test subjects. There was no correlation between peak-to-peak medio-lateral (ML) bending angles and ground reaction force or speed. On the treadmill, peak-to-peak AP bending angles increased with walking and running speed, but peak-to-peak torsion angles and peak-to-peak ML bending angles remained constant during walking. Peak-to-peak AP bending angle during treadmill running was speed-dependent and larger than that observed during walking. In contrast, peak-to-peak tibia torsion angle was smaller during treadmill running than during walking. To conclude, bending and torsion of substantial magnitude were observed in the human tibia during walking and running. A systematic distribution of peak amplitude was found during the first and second parts of the stance phase.

    Acute avulsions of unossified ischial apophyses in children may go undetected on radiography. Therapy includes rest and rehabilitation; however, substantial displacement may require surgery. Our purpose is to illustrate the utility of MRI in the detection of these radiographically occult injuries in skeletally immature children. This retrospective study of more than 5 years included children with ischial avulsions who were evaluated with both radiography and MRI within 3 weeks of acute injury. Initially, radiographs were reviewed to identify those children with unossified ischial apophyses. Subsequently, their MRI examinations were assessed for physeal disruption, bone/soft tissue edema, periosteal/perichondrial elevation and disruption. Initial and follow-up radiographs (if available) were reviewed. Patient age, symptoms and offending activity were determined from clinical records. Five children met inclusion criteria. All initial radiographs were normal. MRI showed: edema (n = 5), periosteal elevation (n = 4), periosteal/perichondrial disruption (n = 4), >5.5 mm displacement (n = 0). Follow-up radiographs in two children (2 and 2.5 months from MRI) showed osseous ischial irregularity. The apophyses remained unossified. Acute unossified ischial apophyseal avulsions in children may be radiographically undetected. In the setting of correlative clinical symptoms, MRI can be used to identify these injuries and to help direct appropriate therapy. (orig.)

    Radiographs are essential in dental practice today. Due to the exposure of patients to X-rays every radiograph has to be justified. The advantages and disadvantages of risks and diagnostic rewards have to be weighed against one another whenever X-ray imaging is considered. An important factor in this respect is the usefulness (in terms of sensitivity and specificity) of a radiograph and along with that, the monitoring of the quality of the entire process, from positioning the photo up to and including the development or scanning of it. Both for children and adults the indication for taking radiographs must be made on an individual basis. The most important considerations are: caries experience, oral hygiene and nutritional habits and exposure to fluorides. Based on these factors an individual risk assessment can be made and the possible benefit of bitewing radiographs for the dental treatment can be determined. European guidelines give advice on the indications and frequency of radiographs in, among other fields, periodontology, endodontology and implantology. PMID:26210219

  11. Radiographic manifestations of arthritis in AIDS patients

    International Nuclear Information System (INIS)

    The purpose of this study is to familiarize the radiologist with a newly discovered association between arthritis and acquired immunodeficiency syndrome (AIDS). The authors retrospectively reviewed the clinical and radiographic findings in 31 patients with human immunodeficiency virus (HIV) infection referred to their rheumatology clinic with musculoskeletal complaints. The patients carried a wide range of clinical diagnosis including Reiter syndrome, psoriatic arthritis, undifferentiated seronegative arthritis, isolated enthesopathies, rheumatoid arthritis and osteonecrosis. Radiographs were available in 24 of the 31 patients, and in 20 they showed radiographic features of arthritis, which included soft-tissue swelling periarticular osteoporosis, synovial effusions, sacroiliitis, periosteal reaction, joint space narrowing, marginal erosions, and osteonecrosis. Although the radiographic abnormalities were frequently mild, they were significant, given the short duration of disease in many of their patients (weeks to months) at the time radiographs were obtained. The range of radiographic findings in their series was varied and paralleled the wide range of clinical diagnoses. No findings were pathognomonic for HIV-associated arthritis. Nevertheless, HIV infection needs to be considered in any patient belonging to a recognized risk group who presents with musculoskeletal disease. This is particularly important since immunosupressive drugs used for the treatment of arthritis can be detrimental to patients with HIV infection

  12. Radiographic signs and diagnosis of dental disease

    International Nuclear Information System (INIS)

    Dental radiographs are critical for the complete assessment and treatment of dental diseases. Dental radiography is commonly used to evaluate congenital dental defects, periodontal disease, orthodontic manipulations, oral tumors, endodontic treatments, oral trauma, and any situation where an abnormality is suspected. Although standard radiographic equipment and film can be used to produce dental radiographs, dental X-ray equipment and film provide superior quality images and greater convenience of animal patient positioning. An understanding of normal dental radiographic anatomy is important when interpreting dental radiographs. Stage III periodontitis is the earliest stage of periodontal disease at which radiographic abnormalities become apparent. Bone loss associated with periodontal disease can be classified as either horizontal or vertical. Periapical radiolucencies can represent granulomas, cysts, or abscesses, whereas periapical radiodensities may represent sclerotic bone or condensing osteitis. Lytic lesions of the bone of the jaw often represent oral neoplasms. Neoplasms also can displace or disrupt teeth in the dental arch. Resorptive lesions can be external or internal and appear as radiolucent areas involving the external surface of the root or the pulp cavity, respectively. Feline dental resorptive lesions, also known as odontoclastic resorptions, are a specific form of dental resorptive lesions unique to cats

    Although sexually transmitted diseases are a major public health problem at the international level, the relationship between contraception and pelvic infection is seldom examined. Numerous STDs are more difficult to diagnose, more frequent, and more serious in women than in men. Differential diagnosis between pelvic infection and other intraabdominal syndromes has been a concern for practitioners for years, and many pelvic infections are probably never diagnosed. Lower abdominal pain and sensitivity as well as fever, leucocytosis, accelerated sedimentation rate, inflammatory annexial mass evident on sonography, and microorganisms in the pouch of Douglass and presence of leucocytes in the peritoneal fluid are diagnostic criteria. Apart from errors in treatment resulting from errors in diagnosis, pelvic infections are often inadequately treated, especially in the initial phase before symptoms are confirmed. The exact incidence of pelvic infections in the US is unknown, but pelvic inflammatory disease (PID) accounted for over 200,000 hospitalizations per year between 1970-75. PID carries grave risks of subsequent ectopic pregnancy, chronic pelvic pain, and infertility which is more likely as the number of acute episodes increases. The female genital tract has diverse microenvironments propitious for growth of microorganisms of different types, aerobic and anaerobic. Each anatomic site has specific features conditioning bacterial growth. Histological modifications during the menstrual cycle and pregnancy affect the microbial flora. Except in the case of gonorrhea, it is not known how many female lower genital tract infections spread to the upper tract. Since 1970, several studies have domonstrated a growing diversity of cervical and vaginal flora in asymptomatic subjects. The principal risk factors for PID have been well described in the literature. All contraceptive methods except the IUD provide some degree of protection against PID. Even among IUD users the risk of

    Pelvic organ prolapse (POP) and urinary tract infection (UTI) are important problems, estimated to affect around 14 and 40 % of women, respectively, at some point in their lives. Positive urine culture in the presence of symptoms is the cornerstone of diagnosis of UTI and should be performed along with ultrasound assessment of postvoid residual (PVR) in all women presenting with POP and UTI. PVR over 30 mL is an independent risk factor for UTI, although no specific association with POP and UTI has been demonstrated. The use of prophylactic antibiotics remains controversial. The major risk factors for postoperative UTI are postoperative catheterisation, prolonged catheterisation, previous recurrent UTI and an increased urethro-anal distance-suggesting that global pelvic floor dysfunction may play a role.

    Full Text Available Nontraumatic anterior subluxation and dislocation of the hip joint are extremely rare. A 58-year-old woman presented to our outpatient clinic with left hip pain with a duration of 15 years. There was no history of trauma or other diseases. Her hip pain usually occurred only on walking and not at rest. Physical examinations demonstrated no tenderness in the hip joint. The range of motion of both hip joints was almost normal. Laxity of other joints was not observed. The bone mineral density of the lumbar spine and proximal femur confirmed a diagnosis of osteoporosis. A plain radiograph showed osteoarthritic changes of the hip joints, severe posterior pelvic tilt, and superior displacement of both femoral heads, especially in a standing position. Three-dimensional computed tomography (3DCT revealed anterior subluxation of both femoral heads. Seven years after the initial visit, both hip joints showed progression to severe osteoarthritis. Although the exact cause remains unclear, lumbar kyphosis, posterior pelvic tilt, and a decrease in acetabular coverage may have influenced the current case. We should be aware of these factors when we examine patients with hip osteoarthritis.

    The purpose of this study was to determine the prevalence and the distribution as well as male/female differences in patients with hip or pelvic pain based on MRI results. Three hundred forty consecutive conscripts (45 women, 295 men; age range 18-29 years; mean age 20.7 years) suffering from stress-related hip, buttock or groin pain took part in the study. All 340 patients underwent MR imaging. Radiographic data were available for 215 patients. Two radiologists interpreted the images by consensus. In MRI 174 stress injuries were diagnosed in 137 patients (32 women, 105 men). The incidence of bone stress injuries in women was significantly higher than that in men (p<0.0001). One hundred five of the injuries (60%) were related to the proximal femur, 70 (67%) to the neck, 34 (32%) to the proximal shaft, and one (1%) to the head. Sixty-nine of the 174 stress injuries (40%) concerned the pelvic bones: sacrum 28 (41%); inferior pubic ramus 34 (49%); superior pubic ramus 3 (4%); iliac bone 3 (4%); and acetabulum 1 (1%). In 31 of the 174 cases (18%) symptoms were contralateral to MR findings. Thirty-three of the 137 patients (24%) had multiple bone stress injuries, 29 had two bone stress injuries and 4 patients had three. The sensitivity of radiography was 37%, specificity 79%, accuracy 60%, positive predictive value 59% and negative predictive value 61%. The kappa value for agreement between radiography and MRI was poor (0.17, p=0.0008). Patients suffering from stress-related hip pain MRI revealed bone stress injuries in 40%; of these, 60% were located in the proximal femur and 40% in the pelvic bones. For accurate diagnosis of bone stress injuries, and to ensure appropriate treatment, the entire pelvis and both proximal femurs should be studied simultaneously by means of MRI. (orig.)

    To clinically implement MRI simulation or MRI-alone treatment planning requires comprehensive end-to-end testing to ensure an accurate process. The purpose of this study was to design and build a geometric phantom simulating a human male pelvis that is suitable for both CT and MRI scanning and use it to test geometric and dosimetric aspects of MRI simulation including treatment planning and digitally reconstructed radiograph (DRR) generation. A liquid filled pelvic shaped phantom with simulated pelvic organs was scanned in a 3T MRI simulator with dedicated radiotherapy couch-top, laser bridge and pelvic coil mounts. A second phantom with the same external shape but with an internal distortion grid was used to quantify the distortion of the MR image. Both phantoms were also CT scanned as the gold-standard for both geometry and dosimetry. Deformable image registration was used to quantify the MR distortion. Dose comparison was made using a seven-field IMRT plan developed on the CT scan with the fluences copied to the MR image and recalculated using bulk electron densities. Without correction the maximum distortion of the MR compared with the CT scan was 7.5 mm across the pelvis, while this was reduced to 2.6 and 1.7 mm by the vendor’s 2D and 3D correction algorithms, respectively. Within the locations of the internal organs of interest, the distortion was phantom allows end-to-end testing of the MRI simulation workflow with comparison to the gold-standard CT based process. MRI simulation was found to be geometrically accurate with organ dimensions, dose distributions and DRR based setup within acceptable limits compared to CT.

These tumors commonly arise from the cranial nerves as acoustic neurinomas but they are extremely rare in the pelvis and the retroperitoneal area (less than 0.5% of reported cases, unless they are combined with von Recklinghausen disease (type 1 neurofibromatosis. We report the case of a 58-year-old female with pelvic schwannoma, 6.5 × 5.5 cm in size, in the right parametrium. This is the first case reported in the literature. Based on the rarity of this tumor and in order to ensure optimum treatment and survival for our patient, we performed laparotomy with total abdominal hysterectomy and en-block tumor excision. A frozen section was taken during the surgery before complete resection of the mass, which was ambiguous. Because of the possibility of malignancy, complete excision of the mass was performed, with pelvic blunt dissection. Histological examination showed a benign neoplasm, originating from the cells of peripheral nerve sheaths; diagnosis was a schwannoma. There were degenerative areas, including cystic degeneration, hemorrhagic infiltrations, ischemic foci with pycnotic cells, and collagen replacement. Pelvic schwannomas are rare neoplasms that can be misdiagnosed. Laparoscopy is a safe

    2011-01-01

    Full Text Available Abdominal-pelvic actinomycosis is often mistaken for other conditions, presenting a preoperative diagnostic challenge. In a 46-year-old female, computed tomography showed an abdominal-pelvic retroperitoneal mass extending from the lower pole of the right kidney to the lower pelvis. The patient had a 3-year history of intrauterine device. The mass appeared to involve the ascending colon, cecum, distal ileum, right Fallopian tube and ovary, and ureter anteriorly and the psoas muscle posteriorly. The resection of retroperitoneal mass, distal ileum appendicectomy, right hemicolectomy, and right salpingo-oophorectomy was performed. The postoperative period was uneventful. Penicillin therapy was given for six months without any complication. The retroperitoneal mass measured 4.5 × 3.5 × 3 cm, surrounded adjacent organs and histologically showed inflammatory granulomatous tissue, agglomeration of filaments, and sulfur granules of Actinomyces, with positive reaction with periodic acid Schiff. Right tubo-ovarian abscess was present. Abdominalpelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intrauterine device.

    In this longitudinal population study, the aims were to study associations of mode of delivery with new onset of pelvic pain and changes in pelvic pain scores up to 7 to 18 months after childbirth. We included 20,248 participants enrolled in the Norwegian Mother and Child Cohort Study (1999-2008) without preexisting pelvic pain in pregnancy. Data were obtained by 4 self-administered questionnaires and linked to the Medical Birth Registry of Norway. A total of 4.5% of the women reported new onset of pelvic pain 0 to 3 months postpartum. Compared to unassisted vaginal delivery, operative vaginal delivery was associated with increased odds of pelvic pain (adjusted odds ratio [OR]: 1.30; 95% confidence interval [CI]: 1.06-1.59). Planned and emergency cesarean deliveries were associated with reduced odds of pelvic pain (adjusted OR: 0.48; 95% CI: 0.31-0.74 and adjusted OR: 0.65; 95% CI: 0.49-0.87, respectively). Planned cesarean delivery, young maternal age, and low Symptom Checklist-8 scores were associated with low pelvic pain scores after childbirth. A history of pain was the only factor associated with increased pelvic pain scores over time (P = 0.047). We conclude that new onset of pelvic pain after childbirth was not commonly reported, particularly following cesarean delivery. Overall, pelvic pain scores were rather low at all time points and women with a history of pain reported increased pelvic pain scores over time. Hence, clinicians should follow up women with pelvic pain after a difficult childbirth experience, particularly if they have a history of pain. PMID:26588694

  7. The diagnostic value of CT of pelvic masses in children

    International Nuclear Information System (INIS)

    Objective: To retrospectively analyze CT appearances and diagnostic value of pelvic masses in 50 children proved by operation and pathology. Methods: 50 cases of pelvic masses were performed with axial plain CT scan. 32 cases of them underwent contrast-enhanced CT scan. These were 31 girls and 19 boys. The age ranged from 2 hours to 14 years, mean 5.8 years. 47 cases were proved by surgical pathology, 2 cases by biopsy pathology, and 1 case by voiding cystourethrography. Results: The pelvic masses were : 27 germ cell tumors, 7 rhabdomyosarcomas (RMS), 4 tumors of neural origin, 2 hydrometrocolpos, 1 pelvic lipomatosis, 1 ureterocele in bladder, 1 non-Hodgkin's lymphoma(NHL), 1 ectopic hyperplasia of prostate in pelvic, 1 appendiceal abscess, 1 prostatic abscess,1 megabladder, 1 mesenteric cyst, 1 duplication of the small intestine, 1 leiomyosarcoma. 46 of 50 cases were correctly diagnosed by CT scan before surgery (92 %), 4 cases were mistaken by CT scan (8 %). 31 cases were benign masses (62%), and 19 cases were malignant masses (38% ), 17 of 19 malignant masses were solid (89.5%). 29 of 31 benign masses were mixed density masses and cystic masses(93. 5%) . Conclusion: CT scan was the best method of choices in showing the size, density, shape, and location of pelvic masses and its relationship to pelvic organs, musculature, and bones. Pelvic CT is the most recent technique utilized in the diagnosis of patients with pelvic masses

  8. Isolated Pelvic Hyperthermochemotherapeutic Perfusion -An Experimental Study on Isolating Efficacy

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Hyperthermochemotherapeutic perfusion model through isolated pelvic vessels was developed to evaluate the leakage of hyperthermia and drugs (such as adriamycin) from the isolated pelvic circulation to systemic circulation and its associated side/toxic effects. The isolated pelvic circulation was perfused through a femoral artery catheter with hyperthermic (48 ℃ to 55 ℃) adriamycin solution (50 μg/ml) for 30 min. The efflux was drained through a femoral vein catheter. And the pelvic temperature was kept at the level of 43±0.5 ℃. The temperature of pelvic circulation was kept at 4 ℃ to 5 ℃ greater than the systemic/core temperature. The adriamycin concentration of pelvic efflux was 12 to 46 folds of that of systemic serum. The difference between them was very significant (P<0.001). As the perfusion pressure was increased, which kept lower than the mean systemic artery pressure, the leakage of the adriamycin from the isolated pelvic circulation to systemic circulation was increased, but there was no significant difference between them (P>0.05). During isolated perfusion, the systemic blood dynamics remained stable and there were no organic injuries on the important organs. It was suggested that the isolating efficacy of the modality of isolated pelvic hyperthermochemotherapeutic perfusion through vessels was rather high. The hyperthermia and drugs could be effectively limited in the isolated pelvic region with minor side effects on the systemic circulation and important organs.

    The bilateral sagittal split osteotomy (BSSO) is one of the main orthognathic surgery procedures used for managing skeletal mandibular excess, deficiency or asymmetry. It is known to be a technique-sensitive procedure with high reported incidences of inferior alveolar nerve injury, bad splits and post-surgical relapse. With the increasing use of computer-assisted techniques in orthognathic surgery, the accurate transfer of the virtual plan to the operating room is currently a subject of research. This study evaluated the efficacy of computer-generated device at maintaining the planned condylar position and minimizing inferior alveolar nerve injury during BSSO. The device was used in 6 patients who required isolated mandibular surgery for correction of their skeletal deformities. Clinical evaluation showed good recovery of the maximal incisal opening and a reproducible occlusion in 5 of the 6 patients. Radiographic evaluation showed better control of the condyle position in both the vertical and anteroposterior directions than in the mediolateral direction. The degree of accuracy between the planned and achieved screw positions were judged as good to excellent in all cases. Within the limitations of this study and the small sample size, the proposed device design allowed for good transfer of the virtual surgical plan to the operating room.

    This is a report of the activities in the radiographic inspection department of Japanese Society for Non-destructive Inspection. The contents of activities are described about the following 15 items: standards, minimum discernible contrast and image distribution, contrast meter and penetrameter sensitivity, testing conditions, detection limit and simulation, photographing method for tube welding and corner welding, relationship between irradiation direction and flaw detectability, abnormal images, RI sources, X-ray equipment and observing device, sensitive materials, detectors, image processing and X-ray TV and automation, neutron radiography, other application and new techniques, and safety. Concerning the ''standards'', discussion was performed on revising JIS Z 3105 ''Methods of Radiographic Test and Classification of Radiographs for Aluminum Welds''. In ''Abnormal images'', the verification by the author that the abnormal shadows generated in the radiographic images of austenitic steel welded parts are the diffraction phenomenon to satisfy the Bragg's conditions is reported. In ''RI sources'', Yb-169 was found to be a good radiation source for relatively thin steel plates. In ''neutron radiography'', it was confirmed that the neutron radiography using a cyclotron as a neutron source can be used practically by its fundamental tests. ''Application and new techniques'' include a trial to utilize scattered radiation as a source, the testing method of γ shield for spent fuel transportation, the improvement of X-ray radiographic test for titanium thin plates and thin wall tubes, and others.

    The aim of this study was to review of the literature to determine the radiographic and clinical maxillofacial features of pycnodysostosis emphasizing the main aspects of interest to the dentist in order to make them fit for the proper treatment of this population. It is important to make the diagnosis as early as possible in order to plan the treatment more suitable to provide a better life's quality to the patients. The most frequent clinical maxillofacial features were: grooved palate, midfacial hypoplasia, mandibular hypoplasia and enamel hypoplasia. The most common radiographic maxillofacial features were: obtuse mandibular angle, frontal/parietal/occiptal bossing, open fontanels and sutures, multiple impacted teeth. The earlier diagnostic of pycnodysostosis has a fundamental role in general health of the patients. We consider that is very important that the dentist know recognize the radiographic and clinical maxillofacial features of pycnodysostosis, which allows correct treatment planning avoiding risks and ensuring better life's quality to the patients.

    Pulmonary hypertension is a menacing complication of a number of diseases, which is responsible for high mortality rates and considerably poorer quality of life in a patient. The timely detection for pulmonary hypertension allows timely initiation of treatment, thus improvement in prognosis in the patient. Chest X-ray is the most commonly used radiographic technique for various causes. Physicians' awareness about the radiographic manifestations of pulmonary hypertension may contribute to the earlier detection of this severe disease. Owing to the natural contrast of reflected structures, a chest X-ray film gives a unique opportunity to assess pulmonary circulation vessels, to reveal the signs of pulmonary hypertension, and to estimate trends in the course of the disease. The paper details a procedure for analysis and the normal radiographic anatomy of pulmonary circulation vessels, gives the present classification of pulmonary hypertension, and sets forth its X-ray semiotics.

    Giant colonic diverticulum (GCD), defined as a diverticulum larger than 4 cm, is a rare entity that is generally a manifestation of colonic diverticular disease. Because of its rarity and its variable and non-specific presentation, the diagnosis of GCD depends mainly on imaging findings. Knowledge of the spectrum of radiographic and CT features of the GCD is important in making the correct diagnosis and potentially preventing complications. This review focuses on imaging findings characteristic of GCD as well as its complications and radiographic mimics. Teaching points • Giant colonic diverticulum is a rare complication of diverticulosis.• The most common symptom is abdominal pain presenting in approximately 70 % of patients.• Diagnosis is based on imaging findings with plain abdominal radiographs and MDCT.• Treatment consists of en bloc resection of the diverticulum and affected adjacent colon.

  16. Laparoscopic pelvic sling placement facilitates optimum therapeutic radiotherapy delivery in the management of pelvic malignancy.

    LENUS (Irish Health Repository)

    Joyce, M

    2012-02-01

    BACKGROUND: Radiotherapy has a significant role in the management of pelvic malignancies. However, the small intestine represents the main dose limiting organ. Invasive and non-invasive mechanical methods have been described to displace bowel out of the radiation field. We herein report a case series of laparoscopic placement of an absorbable pelvic sling in patients requiring pelvic radiotherapy. METHODS: Six patients were referred to our minimally invasive unit. Four patients required radical radiotherapy for localised prostate cancer, one was scheduled for salvage localised radiotherapy for post-prostatectomy PSA progression and one patient required adjuvant radiotherapy post-cystoprostatectomy for bladder carcinoma. All patients had excessive small intestine within the radiation fields despite the use of non-invasive displacement methods. RESULTS: All patients underwent laparoscopic mesh placement, allowing for an elevation of small bowel from the pelvis. The presence of an ileal conduit or previous surgery did not prevent mesh placement. Post-operative planning radiotherapy CT scans confirmed displacement of the small intestine allowing all patients to receive safely the planned radiotherapy in terms of both volume and radiation schedule. CONCLUSION: Laparoscopic mesh placement represents a safe and efficient procedure in patients requiring high-dose pelvic radiation, presenting with unacceptable small intestine volume in the radiation field. This procedure is also feasible in those that have undergone previous major abdominal surgery.

  17. Initial image interpretation of appendicular skeletal radiographs: A comparison between nurses and radiographers

    International Nuclear Information System (INIS)

    Purpose: To examine the effect of a short training programme on nurses and radiographers, exploring differences between their performance before and after training. Method: Twenty-two nurses and 18 radiographers interpreted 20 trauma radiographs of the appendicular skeleton before and after training. Normal and abnormal cases of a discriminatory nature were included. Total score, sensitivity and specificity values were calculated for each participant by comparison with an agreed expected answer. The area under the curve (AUC) was analysed using alternate free-response receiver operating characteristic (AFROC) methodology. Results: Significant differences were demonstrated between the total scores achieved by the two groups (pre-training: p = 0.007, post-training: p = 0.04). After training, the mean score increased significantly for both groups (p < 0.001). No significant difference was found between the radiographers mean pre-training scores and the nurses mean post-training scores (p = 0.66). Sensitivity for both groups increased following training, significantly so for the nurses (nurses: p < 0.001, radiographers: p = 0.06). Specificity reduced significantly after training for the nurses (p < 0.001), and increased for the radiographers but not significantly (p = 0.085). After training, there was no significant difference between the two groups in terms of sensitivity (p = 0.09) but specificity was significantly higher for the radiographers (p < 0.001). The radiographers achieved higher pre-training AUC values than the nurses (p = 0.04), although a difference remained after training this did not achieve statistical significance (p = 0.15). The AUC values increased significantly after training for both groups (nurses: p = 0.012, radiographers: p = 0.004) and again there was no significant difference between the radiographers pre-training performance and the nurses post-training performance (p = 0.62). Conclusion: Improvement after training was seen in both groups

    In spite of the widespread availability of CT scanners, conventional X-ray radiographs remain the basic imaging modality in patients with pelvic and/or acetabular trauma. However, the extent of their use will depend on local utilities (e.g., availability of CT scanners) and on the patient's clinical condition. Regarding the inaccuracy of conventional radiography in the diagnosis of injuries of the dorsal pelvic ring and of the acetabulum, computed tomography represents the most important imaging modality in the clinically stable patient. CT provides an exact staging of the extent of trauma and allows for differentiation of pelvic instabilities. CT clearly demonstrates the severity of acetabular trauma and is superior in the detection of local complicating factors, i.e., impressions fractures and (sub-)luxations of the femoral head as well as free intraarticular fragments. CT findings provide the basis for definite treatment regimens of the injured patient. By extension of the examination, all relevant organs and systems (craniospinal, cardiovascular, gastrointestinal, respiratory, genitourinary) can be imaged during one session. The speed of spiral CT scanners and their diagnostic accuracy will play a major role in the management of, especially, polytraumatized patients. The indication for angiography with the option of therapeutic embolization exists if a pelvic bleeding persists even after reposition and operative fixation of the injury. (orig.)

  20. The etiology of pelvic inflammatory disease.

    Science.gov (United States)

    Keith, L; Berger, G S

    1984-05-01

    The etiology of pelvic inflammatory disease (PID) is speculated upon based on reported incidence and epidemiological studies. In Western society, the incidence of PID (annual) is 1% among women aged 15-34 years and 2% in the high risk group of women aged 15-24 years. The annual incidence in the US is higher, at least 2% among fecund sexually active women aged 13-44 years. The medical consequences of PID are infertility, ectopic pregnancy, and chronic pelvic pain. Causative agents include Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma hominis and various other aerobic and anaerobic microorganisms; however, the natural genital flora of females is so varied that determining actual causative agents is difficult. some case-control studies have determined risk factors for PID; these include particularly current or prior use of IUD, prior pelvic surgery, sexual activity (including number of partners), race, and prior PID acute infection. PID is not a sexually transmitted disease, but rather is classified as sexually derived. Use of barrier methods and oral contraceptives protects against PID. IUD use greatly increases the risk of PID, probably because of the avenue the device provides for organisms to ascend from the lower to the upper genital tract. The role of males in PID etiology is currently the subject of much discussion. It is theorized that the mechanical action of penis insertion in intercourse helps to move causative agents to the upper genital region; also, semen may carry vaginal flora through the cervical opening into the uterus and tubes. Menstruation and PID are closely associated, perhaps because the cervix dilates during bleedings. Research areas include: determination of role of sexual activity (and number of partners) in PID etiology; evaluation of events of menstruation that are predisposing; evaluation of relationship between bacteriosperma and lower and upper genital infections; relationship of particular contraceptive methods to PID

    Rectocolonic calcification was detected radiographically in 17 sites in 14 patients undergoing excretory urography for the assessment of urinary schistosomiasis. The right colon was involved in 11 sites, the rectum in four, and the left colon in two. The pattern of calcification varied according to the degree of bowel distension. A laminar pattern was common to all sites and occurred when the rectum or colon was distended with air, feces, or barium. A laminar or irregular amorphous density was found in the empty colon, whereas the calcified, empty rectum had a corrugated pattern. Rectocolonic calcification is probably the most common radiographic manifestation of schistosomal infestation of the gastrointestinal tract. PMID:6609576

Following abdomino-perineal resection for rectal adenocarcinoma, the posterior perineum is frequently pendulous, particularly in male patients. In order to include the perineal scar and adjacent tissues in the irradiated volume, the caudal edge of the radiation fields is extended caudally. The external genitalia are frequently within the extended radiation field. A technique has been developed that pushes or elevates the perineum 3-5 cm cephalad during pelvic irradiation

    Magnetic resonance (MR) imaging is gaining increased acceptance in the emergency setting despite the continued dominance of computed tomography. MR has the advantages of more precise tissue characterization, superior soft tissue contrast, and a lack of ionizing radiation. Traditional barriers to emergent MR are being overcome by streamlined imaging protocols and newer rapid-acquisition sequences. As the utilization of MR imaging in the emergency department increases, a strong working knowledge of the MR appearance of the most commonly encountered abdominopelvic pathologies is essential. In this article, MR imaging protocols and findings of acute pelvic, scrotal, and gastrointestinal pathologies are discussed. PMID:27150327

    We report on two cases of posttraumatic ileus after pelvic ring fracture in two patients aged 73 and 74 years, respectively. Although all conservative measures were exhausted, in both cases the ileus resulted in additional operative procedures and a significant extension of the hospital stay. Intraoperatively both patients presented with a mechanical ileus caused by adhesions which were unapparent for decades. Only the trauma-related motility disorder led to a clinical manifestation. Pathophysiological mechanisms and their implications on prophylaxis and therapy are discussed. PMID:25432671

  5. A comparison of radiographer and radiologist reports on radiographer conducted barium enemas

    International Nuclear Information System (INIS)

    Purpose: To compare radiographer and radiologist reports on radiographer conducted barium enemas. Method: Two specially trained, experienced radiographers performed barium enemas and prepared provisional reports without consulting radiologists. Later, formal radiologist reports were issued. The reports of each were compared and correlated with clinical findings derived from case note review. Results:Seven hundred and eighty eight patients had barium enemas. Males numbered 295 (37.5%) and females 493 (62.5%). Patients ages ranged from 17 to 95 years (mean 62). The radiologist reported 244 as normal, 432 as diverticular change, 70 with polyps (31 of which had co-existent diverticular disease), 31 with carcinomas and 12 with colitis (three of which had co-existent diverticular disease). Taking the radiologist reports as gold-standard radiographer reports were concordant in 753 (95.5%). There were 35 (4.5%) discordant radiographer reports of these 19 were false-positive diagnoses of polyps and six false positive diagnoses of diverticular change. There were seven false-negative diagnoses of polyps (only one of these was found to have a polyp at follow-up endoscopy). There was one false-negative diagnosis of colitis and two false-negative reports of diverticular change. On follow up there were no false negative diagnoses of carcinoma by either radiographer or radiologist. There was one concordant false-positive diagnosis of carcinoma. Conclusion:Radiographers with specialized training can report barium enemas to a high standard

    Purpose:To enhance the awareness of rare complications of pelvic fracture and describe the correct diagnosis and effective treatment.Methods:A total of 188 cases of pelvic fractures were retrospectively reviewed,and four patients who suffered from four types of rare pelvic fracture complications were described,namely ureteral obstruction caused by retroperitoneal hematoma-induced abdominal compartment syndrome (ACS),bowel entrapment,external iliac artery injury,and open scrotal sac injury.Results:We demonstrated that combined measures should be employed to prevent the occurrence of ACS following major pelvic fractures.Ureteral catheter support may be a good option at an early stage when ACS occurred.Contrasted computed tomography examination and sufficient awareness are keys to a correct diagnosis of bowel entrapment following pelvic fractures.Recognition of risk factors,early diagnosis,and prompt treatment of suspected injury of the external iliac artery are keys to patient survival and to avoid limb loss.Scrotal and/or testicular injury complicated by pelvic fractures should be carefully treated to maintain normal gonad function.Additionally, establishment of a sophisticated trauma care system and multi-disdplinary coordination are important for correct diagnosis and treatment of rare complications in pelvic fractures.Conclusions:Rare complications of pelvic fractures are difficult to diagnose and negatively impact outcome.Recognition of risk factors and sufficient awareness are essential for correct diagnosis and prompt treatment.

  12. Radiographer commenting of trauma radiographs: a survey of the benefits, barriers and enablers to participation in an Australian healthcare setting

    International Nuclear Information System (INIS)

    Radiographer abnormality detection systems that highlight abnormalities on trauma radiographs ('red dot' system) have been operating for more than 30 years. Recently, a number of pitfalls have been identified. These limitations initiated the evolution of a radiographer commenting system, whereby a radiographer provides a brief description of abnormalities identified in emergency healthcare settings. This study investigated radiographers' participation in abnormality detection systems, their perceptions of benefits, barriers and enablers to radiographer commenting, and perceptions of potential radiographer image interpretation services for emergency settings. A cross-sectional survey was implemented. Participants included radiographers from four metropolitan hospitals in Queensland, Australia. Conventional descriptive statistics, histograms and thematic analysis were undertaken. Seventy-three surveys were completed and included in the analysis (68% response rate); 30 (41%) of respondents reported participating in abnormality detection in 20% or less of examinations, and 26(36%) reported participating in 80% or more of examinations. Five overarching perceived benefits of radiographer commenting were identified: assisting multidisciplinary teams, patient care, radiographer ability, professional benefits and quality of imaging. Frequently reported perceived barriers included 'difficulty accessing image interpretation education', 'lack of time' and 'low confidence in interpreting radiographs'. Perceived enablers included 'access to image interpretation education' and 'support from radiologist colleagues'. A range of factors are likely to contribute to the successful implementation of radiographer commenting in addition to abnormality detection in emergency settings. Effective image interpretation education amenable to completion by radiographers would likely prove valuable in preparing radiographers for participation in abnormality detection and commenting systems in

  15. Radiographic interpretation of the appendicular skeleton: A comparison between casualty officers, nurse practitioners and radiographers

    International Nuclear Information System (INIS)

    Aim: To assess how accurately and confidently casualty officers, nurse practitioners and radiographers, practicing within the emergency department (ED), recognize and describe radiographic trauma within an image test bank of 20 appendicular radiographs. Method: The participants consisted of 7 casualty officers, 13 nurse practitioners and 18 radiographers. All 20 radiographic examinations selected for the image test bank had been acquired following trauma and included some subtle, yet clinically significant abnormalities. The test bank score (maximum 40 marks), sensitivity and specificity percentages were calculated against an agreed radiological diagnosis (reference standard). Alternative Free-response Receiver Operating Characteristic (AFROC) analysis was used to assess the overall performance of the diagnostic accuracy of these professional groups. The variation in performance between each group was measured using the analysis of variance (ANOVA) test, to identify any statistical significant differences in the performance in interpretation between these groups. The relationship between the participants' perceived image interpretation accuracy during clinical practice and the actual accuracy of their image test bank score was examined using Pearson's Correlation Coefficient (r). Results: The results revealed that the radiographers gained the highest mean test bank score (28.5/40; 71%). This score was statistically higher than the mean test bank scores attained by the participating nurse practitioners (21/40; 53%) and casualty officers (21.5/40; 54%), with p < 0.01 and p = 0.02, respectively. When compared with each other, the scores from these latter groups showed no significant difference (p = 0.91). The mean 'area under the curve' (AUC) value achieved by the radiographers was also significantly higher (p < 0.01) in comparison to the AUC values demonstrated by the nurse practitioners and casualty officers, whose results, when compared, showed no significant

    [Purpose] This study aimed to determine the correlation between pelvic floor muscle strength and pulmonary function. In particular, we examined whether pelvic floor muscle exercises can improve pulmonary function. [Subjects] Thirty female college students aged 19-21 with no history of nervous or musculoskeletal system injury were randomly divided into experimental and control groups. [Methods] For the pulmonary function test, spirometry items included forced vital capacity and maximal voluntary ventilation. Pelvic floor muscle exercises consisted of Kegel exercises performed three times daily for 4 weeks. [Results] Kegel exercises performed in the experimental group significantly improved forced vital capacity, forced expiratory volume in 1 second, PER, FEF 25-75%, IC, and maximum voluntary ventilation compared to no improvement in the control group. [Conclusion] Kegel exercises significantly improved pulmonary function. When abdominal pressure increased, pelvic floor muscles performed contraction at the same time. Therefore, we recommend that the use of pelvic floor muscle exercises be considered for improving pulmonary function. PMID:26644681

  18. Penile Rehabilitation after Pelvic Cancer Surgery

    2015-01-01

    Full Text Available Erectile dysfunction is the most common complication after pelvic radical surgery. Rehabilitation programs are increasingly being used in clinical practice but there is no high level of evidence supporting its efficacy. The principle of early penile rehabilitation stems from animal studies showing early histological and molecular changes associated with penile corporal hypoxia after cavernous nerve injury. The concept of early penile rehabilitation was developed in late nineties with a subsequent number of clinical studies supporting early pharmacologic penile rehabilitation. These studies included all available phosphodiesterase type 5 inhibitors, intracavernosal injection and intraurethral use of prostaglandin E1 and to lesser extent vacuum erectile devices. However, these studies are of small number, difficult to interpret, and often with no control group. Furthermore, no studies have proven an in vivo derangement of endothelial or smooth muscle cell metabolism secondary to a prolonged flaccid state. The purpose of the present report is a synthetic overview of the literature in order to analyze the concept and the rationale of rehabilitation program of erectile dysfunction following radical pelvic surgery and the evidence of such programs in clinical practice. Emphasis will be placed on penile rehabilitation programs after radical cystoprostatectomy, radical prostatectomy, and rectal cancer treatment. Future perspectives are also analyzed.

  19. Immune mediators of chronic pelvic pain syndrome.

    The cause of chronic pelvic pain syndrome (CPPS) has yet to be established. Since the late 1980s, cytokine, chemokine, and immunological classification studies using human samples have focused on identifying biomarkers for CPPS, but no diagnostically beneficial biomarkers have been identified, and these studies have done little to deepen our understanding of the mechanisms underlying chronic prostatic pain. Given the large number of men thought to be affected by this condition and the ineffective nature of current treatments, there is a pressing need to elucidate these mechanisms. Prostatitis types IIIa and IIIb are classified according to the presence of pain without concurrent presence of bacteria; however, it is becoming more evident that, although levels of bacteria are not directly associated with levels of pain, the presence of bacteria might act as the initiating factor that drives primary activation of mast-cell-mediated inflammation in the prostate. Mast cell activation is also known to suppress regulatory T cell (Treg) control of self-tolerance and also activate neural sensitization. This combination of established autoimmunity coupled with peripheral and central neural sensitization can result in the development of multiple symptoms, including pelvic pain and bladder irritation. Identifying these mechanisms as central mediators in CPPS offers new insight into the prospective treatment of the disease. PMID:24686526

    2011-01-01

    Full Text Available Pelvic inflammatory disease (PID, one of the most common infections in nonpregnant women of reproductive age, remains an important public health problem. It is associated with major long-term sequelae, including tubal factor infertility, ectopic pregnancy, and chronic pelvic pain. In addition, treatment of acute PID and its complications incurs substantial health care costs. Prevention of these long-term sequelae is dependent upon development of treatment strategies based on knowledge of the microbiologic etiology of acute PID. It is well accepted that acute PID is a polymicrobic infection. The sexually transmitted organisms, Neisseria gonorrhoeae and Chlamydia trachomatis, are present in many cases, and microorganisms comprising the endogenous vaginal and cervical flora are frequently associated with PID. This includes anaerobic and facultative bacteria, similar to those associated with bacterial vaginosis. Genital tract mycoplasmas, most importantly Mycoplasma genitalium, have recently also been implicated as a cause of acute PID. As a consequence, treatment regimens for acute PID should provide broad spectrum coverage that is effective against these microorganisms.

    Full Text Available Context: Changes in the size of dental pulp caused by the apposition of secondary dentin and occlusal wear are morphometric parameters for estimating age. Aim: To estimate the accuracy of age evaluation by Kvaal's method and the effect of occlusal wear on age using digital intraoral periapical radiographs in a subset of the Indian population. Materials and Methods: A total of 300 teeth were radiographically evaluated using intraoral periapical digital radiographs from 50 adult patients. A few modifications were made in the design of the study compared to the original Kvaal's method. The radiographs of three teeth from each jaw were taken and morphometric measurements in ratios were analyzed, which included the pulp length to tooth length (X1, pulp length to root length (X2, pulp width to root widths at three defined levels (X3, and tooth length to root length (X4. Statistical Analysis: The Pearson product-moment correlation coefficient (PCC between age and the morphological variables showed that among them X1, X2, and X3were statistically significant but not the tooth root length ratio (X4. Conclusions: The ratios X1, X2, and X3were good indicators of age and hence a multiple linear regression model for age estimation was derived using these three variables. However, it was found that X4was not a good indicator of age estimation in said population.

  11. Limbic associated pelvic pain: a hypothesis to explain the diagnostic relationships and features of patients with chronic pelvic pain.

    Science.gov (United States)

    Fenton, Bradford W

    2007-01-01

    Limbic associated pelvic pain is a proposed pathophysiology designed to explain features commonly encountered in patients with chronic pelvic pain, including the presence of multiple pain diagnoses, the frequency of previous abuse, the minimal or discordant pathologic changes of the involved organs, the paradoxical effectiveness of many treatments, and the recurrent nature of the condition. These conditions include endometriosis, interstitial cystitis, irritable bowel syndrome, levator ani syndrome, pelvic floor tension myalgia, vulvar vestibulitis, and vulvodynia. The hypothesis is based on recent improvements in the understanding of pain processing pathways in the central nervous system, and in particular the role of limbic structures, especially the anterior cingulate cortex, hippocampus and amygdala, in chronic and affective pain perception. Limbic associated pelvic pain is hypothesized to occur in patients with chronic pelvic pain out of proportion to any demonstrable pathology (hyperalgesia), and with more than one demonstrable pain generator (allodynia), and who are susceptible to development of the syndrome. This most likely occurs as a result of childhood sexual abuse but may include other painful pelvic events or stressors, which lead to limbic dysfunction. This limbic dysfunction is manifest both as an increased sensitivity to pain afferents from pelvic organs, and as an abnormal efferent innervation of pelvic musculature, both visceral and somatic. The pelvic musculature undergoes tonic contraction as a result of limbic efferent stimulation, which produces the minimal changes found on pathological examination, and generates a further sensation of pain. The pain afferents from these pelvic organs then follow the medial pain pathway back to the sensitized, hypervigilant limbic system. Chronic stimulation of the limbic system by pelvic pain afferents again produces an efferent contraction of the pelvic muscles, thus perpetuating the cycle. This cycle is

  12. Image rejects/retakes-radiographic challenges

    International Nuclear Information System (INIS)

    A general held position among radiological personnel prior to digitalisation was that the problem of image rejects/retakes should more or less vanish. However, rejects/retakes still impose several challenges within radiographic imaging; they occupy unnecessary resources, expose patients to unnecessary ionizing radiation and may also indicate suboptimal quality management. The latter is the main objective of this paper, which is based on a survey of international papers published both for screen/film and digital technology. The digital revolution in imaging seems to have reduced the percentage of image rejects/retakes from 10-15 to 3-5%. The major contribution to the decrease appears to be the dramatic reduction of incorrect exposures. At the same time, rejects/retakes due to lack of operator competence (positioning, etc.) are almost unchanged, or perhaps slightly increased (due to lack of proper technical competence, incorrect organ coding, etc.). However, the causes of rejects/retakes are in many cases defined and reported with reference to radiographers' subjective evaluations. Thus, unless radiographers share common views on image quality and acceptance criteria, objective measurements and assessments of reject/retake rates are challenging tasks. Interestingly, none of the investigated papers employs image quality parameters such as 'too much noise' as categories for rejects/retakes. Surprisingly, no reject/retake analysis seems yet to have been conducted for direct digital radiography departments. An increased percentage of rejects/retakes is related to 'digital skills' of radiographers and therefore points to areas for extended education and training. Furthermore, there is a need to investigate the inter subjectivity of radiographers' perception of, and attitude towards, both technical and clinical image quality criteria. Finally, there may be a need to validate whether reject/retake rate analysis is such an effective quality indicator as has been asserted

Furthermore, there is a need to investigate the inter-subjectivity of radiographers' perception of, and attitude towards, both technical and clinical image quality criteria. Finally, there may be a need to validate whether reject/retake rate analysis is such an effective quality indicator as has been asserted

The material consisted of profile and panoramic radiographs, taken before orthodontic treatment, of 30 males and 23 females (median age 22, range 18-48 years......Previous studies have suggested methods for predicting third molar tooth eruption radiographically. Still, this prediction is associated with uncertainty. The aim of the present study was to elucidate the association between cephalometric measurements on profile and panoramic radiographs...... the length from the ramus to the incisors (olr-id) showed a statistically significant correlation. By combining this length with the mesiodistal width of the lower second molar, the prediction of eruption of the lower third molar was strengthened.

    International Nuclear Information System (INIS)

    The purpose of this study was radiographic analysis of the morphology of maxillary sinus in adolescents and adults. In order to analyze the morphology of maxillary sinus in view point of anteroposterior width of medial wall, vertical distance between antral floor and nasal floor level, anterior extension, distance between antral floor and maxillary 1st molar apex, and types of lower border of maxillary sinus, specialized maxillary projection and periapical view with paralleling technique was taken. The author examined orthopantomograms and intraoral standard views taken from 400 adolescents and adults ranged 15-65 years-old. The obtained results were as follows: 1. The antero-posterior width of medial wall of maxillary sinus was 32.80 mm in 15-19 year-old group, 33.86 mm in 20-24 year-old group, 34.09 mm in 25-29 year-old group, and 33.67 mm in 30-65 year-old group, and left maxillary sinus was somewhat smaller than the right. 2. The vertical distance between antral floor and nasal floor level was 8.49 mm in 15-19 year-old group, 9.05 mm i n 20-24 year-old group, 8.95 mm in 25-29 year-old group, and 8.32 mm in 30-65 year-old group. 3. The order of anterior extension of maxillary sinus were distal half of canine, mesial half of canine, mesial half of 1st premolar, and distal half of 1st premolar. 4. The distance between antral floor and maxillary 1st molar were 4.36 mm in 15-19 year-old group, 4.77 mm in 20-24 yea r-old group, 3.58 mm in 25-29 year-old group, and 2.33 mm in 30-65 year-old group. 5. The order of the types of lower border of maxillary sinus were entire downward type, close type, partially downward type, waving type, separating type, and indistinct. In the types of antral floor, there was a tendency to increase the separating type with age.

    Objective: To evaluate the roles of radiograph, magnetic resonance imaging (MRI), three-dimensional computed tomography (3-D CT) in early diagnosis of femoro-acetabular impingement (FAI) in 17 cases. Methods: Plain radiographs of the pelvis, 3-D CT, and MRI of the hip were made on 17 patients with groin pain, which was worse with prolonged sitting (i.e. hip flexion). There was no history of trauma or childhood hip disorders in the patients who did not complain of any other joint problems or neurologic symptoms. All patients had positive anterior or posterior impingement test. Plain radiographs included an antero-posterior (AP) view of the hip and a cross table lateral view with slight internal rotation of the hip. CT scan was performed with the Lightspeed 16 row spiral (General Electric Company, USA) at 1.25 mm slice reconstruction. MRI scan was performed on the Siemens Avanto (Siemens Company, Germany)1.5T supraconducfion magnetic resonance meter. The CT and MRI scans were taken from 1 cm above the acetabulum to the lesser trochanter in 5 series. Results: The plain radiographs of the pelvis showed that among the 17 patients, 12 (70.59%) had "Cam" change of the femoral head, 6 (35.29%) had positive "cross-over" sign, and 17 (100%) had positive "Pincer" change of the acetabulum. The 16 row spiral CT noncontrast enhanced scan and 3-D reconstruction could discover minus femoral offset and ossification and osteophyte of the acetabulum labrum in all the 17 cases (100%). The MRI noncontrast enhanced scan could discover more fluid in the hip joint in 15 cases (88.33%), subchondral ossification in 3 cases (17.6%), and labium tears in 3 cases (17.6%). Conclusions: Plain radiographs can provide the initial mainstay for the diagnosis of FAI, 3-D CT can tell us the femoral offset, while MRI can show labrum tears in the very early stage of FAI. Basically, X-ray examination is enough for the early diagnosis of FAI, but 3-D CT and MRI may be useful for the treatment.

    Full Text Available Introduction: Chronic pelvic pain (CPP is a common medical problem affecting women. Too often the physical signs are not specific. This study aims at determining the accuracy of diagnostic laparoscopy over clinical pelvic examination. Settings and Design: A retrospective study of patients who underwent diagnostic laparoscopy for CPP. Materials and Methods: The medical records of 86 women who underwent laparoscopic evaluation for CPP of at least 6-month duration were reviewed for presentation of symptoms, pelvic examination findings at the admission, operative findings and follow up when available. Statistical analysis used: McNemar Chi-square test for frequencies in a 2 x 2 table. Results: The most common presentation was acyclic lower abdominal pain (79.1%, followed by congestive dysmenorrhoea (26.7%. 61.6% of women did not reveal any significant signs on pelvic examination. Pelvic tenderness was elicited in 27.9%. Diagnostic laparoscopy revealed significant pelvic pathology in 58% of those who essentially had normal pervaginal findings. The most common pelvic pathology by laparoscopy was pelvic adhesions (20.9%, followed by pelvic congestion (18.6%. Laparoscopic adhesiolyis achieved pain relief only in one-third of the women. Conclusion: The study revealed very low incidence of endometriosis (4.7%. Overall clinical examination could detect abnormality in only 38% of women, where as laparoscopy could detect significant pathology in 66% of women with CPP. This shows superiority of diagnostic laparoscopy over clinical examination in detection of aetiology in women with CPP (P < 0.001. Adhesiolysis helps only small proportion of women in achieving pain control.

    To determine the best flow alternation in the internal iliac arteries for regional chemotherapy using a reservoir to treat pelvic malignancies, collateral arteries that arose after arterial flow alternation were evaluated on follow-up pelvic angiographies. Follow-up angiographies were obtained in 11 patients with 21 embolized arteries; six male and five female patients including three with urinary bladder cancer, two with prostate cancer, four with uterine cervical cancer and two with bone metastasis. The interval until follow-up angiography ranged from one to-28 months (mean 8.9 months). Three radiologists interpreted the angiographic results and evaluated collateral vessels. Among 21 embolized arteries, 19 were well occluded, while two were not blocked completely. The two arteries with incomplete embolization did not induce collaterals. Eight internal iliac arteries occluded at the proximal portion enhanced retrogradely via collaterals from the ipsilateral external iliac arteries. Collaterals between the bilateral internal iliac arteries were noted only in four of them. In conclusion, embolization at the proximal point of the internal iliac arteries usually induced collaterals from the ipsilateral external iliac arteries and did not always from collaterals between the bilateral internal iliac arteries, which were necessary for regional chemotherapy. This should be considered when pelvic malignancies are treated with reservoirs.

    A 36-year-old woman presented with a palpable tender mass at the left lower quadrant of the abdomen. She had suffered from constipation for five years and had a previous history of intrauterine device-use for one year. Preoperative barium enema and abdominopelvic CT showed a compatible finding of rectosigmoid colon cancer or left ovary cancer. She underwent segmental resection of the sigmoid colon along with the removal of left distal ureter, left ovary and salpinx. Pathologic examination revealed actinomycotic abscesses containing sulfur granules. Thereafter, she took parenteral ampicillin (50mg/kg/day) for one month and oral amoxicillin (250mg, tid) for 2 months consecutively. The patient has no specific problems for 6 months after surgical resection and long-term antibiotic therapy. This report may be the first of intrauterine device-associated pelvic actinomycosis involving both sigmoid colon and rectum extensively. PMID:7576294

    Aim: To evaluate the efficacy of biofeedback therapy in patients with chronic pelvic pain syndrome(CPPS). Methods: From November 2001 to April 2002, patients visiting the Urological Outpatient Clinic of this Hospital were evaluated by means of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI)and classified by the NIH classification standard. Sixty-two patients of CPPS category Ⅲ were involved in this study. All patients had been treated by conventional approaches such as antibiotics and alpha-blockers for more than half a year without any improvement. The expressed prostatic secretion results were as follows: WBC 5 to 9/high power field, lipid +-+++ and bacterial culture negative. Their NIH-CPSI were 12-40. All the 62 cases complained of micturitional irritation (frequency, urgency, splitted stream and sense of residual urine), 32 cases, of pain or discomfort at the testicular, penile, scrotal, pelvic or rectal region and 13 cases, of white secretion-dripping. The patients were treated by the Urostym Biofeedback equipment (Laborie Co., Canada) 5 times a week for 2 weeks with a stimulus intensity of 15 mA-23 mA and duration of 20 minutes. Results: Sixty patients were significantly improved or cured, while no significant improvement in the remaining 2. No apparent side effect was observed. The NIH-CPSI dropped to 6 to 14 with an average reduction of 21 (P<0.01). In the 60 improved cases, pain was relieved after 2-3treatment courses and other symptoms disappeared after 4-5 courses. Conclusion: Biofeedback therapy is a safe and effective treatment for CPPS. Large randomized clinical trials are needed to confirm its efficacy and to explore the mechanism of action.

    1984-04-01

    Eleven common radiographic signs of mediastinal hemorrhage were evaluated by two observers for the following three patient groups: normal subjects, patients with mediastinal hemorrhage and no arterial injury, and patients with major thoracic arterial injury. Supine chest radiographs were studied in all cases. Four major conclusions can be made based upon these finding. M/C ratio (mediastinal width to chest width), tracheal deviation, left hemothorax, paraspinal line widening, and aorto-pulmonary window opacification do not reliably separate these three groups of patients. The diagnosis of mediastinal hemorrhage may be made if the aortic contour is abnormal or if one of the following signs is positive: abnormal mediastinal width, apical cap, widening of the right paratracheal stripe, or deviation of the nasogastric tube. Due to interobserver variation, there is good agreement between observers for the following four signs only: transverse mediastinal width, tracheal deviation, nasogastric tube deviation, nasogastric tube deviation, and right paratracheal stripe widening.

  11. Prediction of Incident Major Osteoporotic and Hip Fractures by Trabecular Bone Score (TBS) and Prevalent Radiographic Vertebral Fracture in Older Men.

    Trabecular bone score (TBS) has been shown to predict major osteoporotic (clinical vertebral, hip, humerus, and wrist) and hip fractures in postmenopausal women and older men, but the association of TBS with these incident fractures in men independent of prevalent radiographic vertebral fracture is unknown. TBS was estimated on anteroposterior (AP) spine dual-energy X-ray absorptiometry (DXA) scans obtained at the baseline visit for 5979 men aged ≥65 years enrolled in the Osteoporotic Fractures in Men (MrOS) Study and its association with incident major osteoporotic and hip fractures estimated with proportional hazards models. Model discrimination was tested with Harrell's C-statistic and with a categorical net reclassification improvement index, using 10-year risk cutpoints of 20% for major osteoporotic and 3% for hip fractures. For each standard deviation decrease in TBS, there were hazard ratios of 1.27 (95% confidence interval [CI] 1.17 to 1.39) for major osteoporotic fracture, and 1.20 (95% CI 1.05 to 1.39) for hip fracture, adjusted for FRAX with bone mineral density (BMD) 10-year fracture risks and prevalent radiographic vertebral fracture. In the same model, those with prevalent radiographic vertebral fracture compared with those without prevalent radiographic vertebral fracture had hazard ratios of 1.92 (95% CI 1.49 to 2.48) for major osteoporotic fracture and 1.86 (95% CI 1.26 to 2.74) for hip fracture. There were improvements of 3.3%, 5.2%, and 6.2%, respectively, of classification of major osteoporotic fracture cases when TBS, prevalent radiographic vertebral fracture status, or both were added to FRAX with BMD and age, with minimal loss of correct classification of non-cases. Neither TBS nor prevalent radiographic vertebral fracture improved discrimination of hip fracture cases or non-cases. In conclusion, TBS and prevalent radiographic vertebral fracture are associated with incident major osteoporotic fractures in older men independent of each other

  12. Assessment of fast radiographic systems by the constant exposure technique

    International Nuclear Information System (INIS)

    The constant exposure technique was applied to compare the radiographic image quality and relative speed of different fast radiographic systems. Conventional industrial X-ray films, exposed with lead intensifying screens, special fast film with fluorometallic screens as well as different brands of radiographic paper exposed both with fluorescent as well as fluorometallic screens were tested and compared. ISO wire IQI's and ASTM penetrameters were used together with 30-mm aluminium and 10-mm steel plates. For all the fast radiographic systems wire sensitivity better than 2 per cent was obtained. The constant exposure technique proved to be adequate for the assessment of fast radiographic systems. (author)

  13. Finding the neck-trunk boundary in snakes: anteroposterior dissociation of myological characteristics in snakes and its implications for their neck and trunk body regionalization.

    2012-09-01

    The neck and trunk regionalization of the presacral musculoskeletal system in snakes and other limb-reduced squamates was assessed based on observations on craniovertebral and body wall muscles. It was confirmed that myological features characterizing the neck in quadrupedal squamates (i.e., squamates with well-developed limbs) are retained in all examined snakes, contradicting the complete lack of the neck in snakes hypothesized in previous studies. However, the posterior-most origins of the craniovertebral muscles and the anterior-most bony attachments of the body wall muscles that are located at around the neck-trunk boundary in quadrupedal squamates were found to be dissociated anteroposteriorly in snakes. Together with results of a recent study that the anterior expression boundaries of Hox genes coinciding with the neck-trunk boundary in quadrupedal amniotes were dissociated anteroposteriorly in a colubrid snake, these observations support the hypothesis that structures usually associated with the neck-trunk boundary in quadrupedal squamates are displaced relative to one another in snakes. Whereas certain craniovertebral muscles are elongated in some snakes, results of optimization on an ophidian cladogram show that the most recent common ancestor of extant snakes would have had the longest craniovertebral muscle, M. rectus capitis anterior, that is elongated only by several segments compared with that of quadrupedal squamates. Therefore, even such a posteriorly displaced "cervical" characteristic plesiomorphically lies fairly anteriorly in the greatly elongated precloacal region of snakes, suggesting that the trunk, not the neck, would have contributed most to the elongation of the snake precloacal region. A similar dissociation of structures usually associated with the neck-trunk boundary in quadrupedal squamates is observed in limb-reduced squamates, suggesting that these forms and snakes may share a developmental mechanism producing modifications in the

    OpenAIRE

    Straiton, J A; Todd, B; Venner, R M

    1987-01-01

    A radiographic technique for measuring conjunct rotation at the knee joint is described. Conjunct rotation was demonstrated to occur over a greater range of values of flexion than conventionally believed. Rotation increased progressively as the knee extended, and was not confined to the last phase of extension. Consideration of such rotatory movement is relevant to the design of knee arthroplasties and also to possible mechanisms of non-bony injury of the knee.

  17. Radiographic imaging of the canine intercondylar fossa

    International Nuclear Information System (INIS)

    The intercondylar fossa is believed to play an important role in the pathology of cranial cruciate ligament rupture and therefore has received considerable attention in the last decade. Accurate radiographic imaging of the intercondylar fossa requires that the central x-ray beam pass through the center of the intercondylar “tunnel”. The anatomy of the canine intercondylar fossa is similar to humans, however, the orientations of the intercondylar fossa's differ. Consequently, the positioning techniques described for humans are not appropriate for the dog. To pass through the center of the dog, intercondylar fossa, the central x-ray beam should be 12° (S.D. 1.7°) caudal from the femoral diaphysis in the sagittal plane and obliqued caudolateral to craniomedial 7° (S.D. 0.60°) (caudo78°proximo7° lateralcraniodistomedial oblique). Cross table positioning was used with the hip flexed and the radiograph cassette placed on the cranial surface of the stifle. However, superimposition of the tuber ischii and soft tissues caudal to the femur made 15° to 20° the best angle obtainable. There was not a significant difference (p = 0.17) in the notch width index between a 12° versus 20° angle of the central x-ray beam caudal to the femoral diaphysis, both with 7° of external rotation of the stifle. The notch width index of 0.252 obtained from radiographic measurements was not significantly different from measurements obtained grossly of 0.254 (n = 26; p = 0.69). Failure to oblique the central x-ray beam caused a significant (p = 0.0008) decrease in the apparent fossa width radiographically

    Major adverse reactions to radiographic contrast media will occur more often as contrast material is now also administered during computerized tomographic (CT) scanning. Differentiation of the two major contrast reactions, the vagus reaction and the anaphylactoid reaction, is essential. Bradycardia is the key finding for identifying the vagus reaction. The vagus reaction involving hypotension and bradycardia requires treatment with large doses of atropine given intravenously. The immediate ge...

    Normative references for radiographic measurements commonly used in the diagnosis of developmental dysplasia of the hip at skeletal maturity are incomplete. The present study therefore aimed to establish new gender-specific standards for measurements reflecting the acetabular morphology, namely Sharp's angle, the acetabular roof angle of Toennis (AA) and the acetabular depth-width ratio (ADR), and measurements reflecting the position of the femoral head related to the acetabulum, namely the center-edge (CE) angle of Wiberg, the refined CE angle of Ogata, and the femoral head extrusion index (FHEI). The joint space width (JSW) is also reported. The population-based 1989 Bergen Birth Cohort (n = 3,935) was invited at age 19 years to a follow-up during 2007-09, of which 2,038 (52 %) attended. A standardized antero-posterior radiograph was assessed. The normative references are presented as mean {+-} standard deviation (SD) and 2.5-97.5 percentiles with 95 % confidence intervals. A total of 2,011 (841 males, 1,170 females, mean age 18.6 (SD 0.6)) radiographs were analyzed. Sharp's angle was 38.8 {+-} 3.5 in males and 40.7 {+-} 3.5 in females, with 97.5 percentiles of 46 and 47 , respectively. The CE angle was 32.1 {+-} 6.1 in males and 31.0 {+-} 6.1 in females, with 2.5 percentiles of 21 and 20 , respectively. The FHEI was 86.0 % {+-} 6.3 % in males and 85.6 % {+-} 6.6 % in females, with 2.5 percentiles of 74 and 73 , respectively. Updated gender-specific reference ranges for radiographic measurements commonly used for hip dysplasia at skeletal maturity are reported, similar to or slightly wider than those described in the literature. Statistically significant gender differences have been confirmed for most of the measurements. (orig.)

    Full Text Available Objectives: To assess the cure rate of patients with premature ejaculation who underwent a treatment involving: 1 awareness of the pelvic floor muscles 2 learning the timing of execution and maintenance of contraction of the pelvic floor muscles during the sensation of the pre-orgasmic phase 3 pelvic floor rehabilitation (bio feed back, pelvic exercises and electrostimulation. Materials and methods: We recruited 78 patients with lifelong premature ejaculation who completed the training. The patients were informed of the role of the pelvic floor. They were taught to carry out the execution and maintenance of contraction of the pelvic floor muscles during the sensation of the pre-orgasmic phase to control the ejaculatory reflex. In order to improve the awareness, the tone and the endurance of the pelvic floor muscles, patients were treated with the rehabilitation of pelvic floor (RPF consisting mainly in biofeedback, pelvic exercises and in some cases also in electro-stimulation (ES. The training was carried out for a period of about 2-6 months with an average of 2-5 visits per cycle. Results: 54% of patients who completed the training were cured of premature ejaculation and learned over time to be able to postpone the ejaculation reflex. In a subgroup of 26 patients was also measured the IELT which on the average increased from < 2 minutes to >10 minutes. The best results occurred mainly in patients aged less than 35 where the cure rate was 65%. There were no side effects. Conclusions: In this study, approximately half of patients with premature ejaculation were cured after applying the above treatment.This therapy, necessitates a fairly long period of time (2-6 months and a great commitment on the part of the patient, nevertheless it can be a valid and effective treatment for patients with premature ejaculation. This treatment makes the patient independent in that he is not bound to specific times for taking medication. Furthermore there are no

    Full Text Available Abstract Background We have occasionally observed clinically noticeable postoperative transverse plane pelvic rotation increase (TPPRI in the direction of direct thoracolumbar/lumbar rotational corrective load applied during posterior instrumentation and arthrodesis for double (Lenke 3 and 6 adolescent idiopathic scoliosis (AIS curves. Our purposes were to document this occurrence; identify its frequency, associated variables, and natural history; and determine its effect upon patient outcome. Methods Transverse plane pelvic rotation (TPPR can be quantified using the left/right hemipelvis width ratio as measured on standing posterior-anterior scoliosis radiographs. Descriptive statistics were done to determine means and standard deviations. Non-parametric statistical tests were used due to the small sample size and non-normally distributed data. Significance was set at P Results Seventeen of 21 (81% consecutive patients with double curves (7 with Lenke 3 curves and 10 with Lenke 6 instrumented with lumbar pedicle screw anchors to achieve direct rotation had a complete sequence of measurable radiographs. While 10 of these 17 had no postoperative TPPRI, 7 did all in the direction of the rotationally corrective thoracolumbar instrumentation load. Two preoperative variables were associated with postoperative TPPRI: more tilt of the vertebra below the lower instrumented vertebra (-23° ± 3.1° vs. -29° ± 4.6°, P = 0.014 and concurrent anterior thoracolumbar discectomy and arthrodesis (5 of 10 vs. 7 of 7, P = 0.044. Patients with a larger thoracolumbar/lumbar angle of trunk inclination or larger lower instrumented vertebra plus one to sacrum fractional/hemicurve were more likely to have received additional anterior thoracolumbar discectomy and arthrodesis (c = 0.90 and c = 0.833, respectively. Postoperative TPPRI resolved in 5 of the 7 by intermediate follow-up at 12 months. Patient outcome was not adversely affected by postoperative TPPRI

  9. 'Women get this': gendered meanings of chronic pelvic pain.

    Science.gov (United States)

    Grace, Victoria M; MacBride-Stewart, Sara

    2007-01-01

    Chronic pelvic pain in women is a key site through which explorations of the meanings of female gender and pain might further insights into the broader question of the embodied experience of women in relation to pain. A biocultural approach is used to present an analysis of interviews with 40 New Zealand women in which they reflect on 'how come' they have chronic pelvic pain. Women consistently employ a mechanistic rendition of medical discourse and understandings in their constructions of 'how come' they have pain, accompanied by a reiteration of 'not knowing' and a normalizing of their pelvic pain. We explore how this normalizing works within the narratives to establish women's pelvic pain as intrinsically gendered. Etiological meanings that are constructed in medical terms and yet are unable to be interpreted within a dualist frame of normality and pathology, we argue, permeate and shape gendered experience of chronic pain conditions.

    2011-01-01

    Full Text Available Background/Aim. Pelvic floor dysfunction is a frequent problem affecting more than 50% of women in peri- and postmenopause. Considering that ageing and menopause befall in the significant factors causing this issue, as well as the expected longevity of women in the world and in our country, pelvic floor dysfunction prevelence is foreseen to be even higher. The aim of the study was to evaluate impact of the symptoms of pelvic dysfunction on quality of life and examine body image satisfaction in adult women with pelvic organ prolapse presenting to tertiary care clinic for surgical treatment. Methods. This prospective case-control study included 50 patients who presented to tertiary care gynecology clinic for surgical treatment and 50 controls with normal pelvic floor support and without urinary incontinence who presented tertiary care gynecology clinic for other reasons. Both, patients and controls, completed two quastionnaires recommended for the evaluation of symptoms (Pelvic floor distress inventory - short forms and quality of life impact (Pelvic floor impact questionnaire - short form of pelvic organ prolapse, and Body Image Scale. Results. The patients scored significantly worse on the prolapse, urinary, colorectal scales and overall score of Pelvic floor distress inventory - 20 than controls subjects (134.91 vs 78.08; p < 0.01. The patients also measured significant decrease in condition- specific quality of life (89.23 vs 3.1; p < 0.01. They were more likely to feel self-conscious (78% vs 42%; p < 0.01, less likely to feel physically attractive (78% vs 22%; p < 0.01, more likely to have difficulty looking at themselves naked (70% vs 42%; p < 0.01, less likely to feel sexually attractive (64% vs 32%; p < 0.01, and less likely to feel feminine (56% vs 16%; p < 0.05, than controls. There were no differencies in their feeling of dissatisfaction with appearance when dressed, avoiding people because of appereance and overall dissatisfaction with

  20. Can pelvic tilting be ignored in total hip arthroplasty?

    Directory of Open Access Journals (Sweden)

    2014-01-01

    CONCLUSION: The sagittal position of pelvis is a key factor in impingement and dislocation after total hip arthroplasty. Pelvic tilting affects the position of acetabular component in the sagittal plane of the body as compared with its anatomic position in the pelvis. We suggest a preoperative lateral view of spine-pelvis, in upright and supine position for evaluation of a corrective adaptation of the acetabular cup accordingly with pelvic balance.

  1. Female Pelvic Vein Embolization: Indications, Techniques, and Outcomes

    Energy Technology Data Exchange (ETDEWEB)

    Lopez, Anthony James, E-mail: consultant@radiologist.co.uk [The Imaging Clinic (United Kingdom)

    2015-08-15

    Until recently, the main indication for pelvic vein embolization (PVE) in women was to treat pelvic venous congestion syndrome (PVC) but increasingly, patients with refluxing pelvic veins associated with leg varicosities are also being treated. A more unusual reason for PVE is to treat pelvic venous malformations, although such lesions may be treated with sclerotherapy alone. Embolotherapy for treating PVC has been performed for many years with several published studies included in this review, whilst an emerging indication for PVE is to treat lower limb varicosities associated with pelvic vein reflux. Neither group, however, has been subjected to an adequate randomized, controlled trial. Consequently, some of the information presented in this review should be considered anecdotal (level III evidence) at this stage, and a satisfactory ‘proof’ of clinical efficacy remains deficient until higher-level evidence is presented. Furthermore, a wide range of techniques not accepted by all are used, and some standardization will be required based on future mandatory prospective studies. Large studies have also clearly shown an unacceptably high recurrence rate of leg varicose veins following venous surgery. Furthermore, minimally or non-invasive imaging is now revealing that there is a refluxing pelvic venous source in a significant percentage of women with de novo leg varicose veins, and many more with recurrent varicosities. Considering that just over half the world’s population is female and a significant number of women not only have pelvic venous reflux, but also have associated leg varicosities, minimally invasive treatment of pelvic venous incompetence will become a common procedure.

    Body image, including how a woman views her genitals, has been shown to impact sexuality. Currently, there are no valid and reliable questionnaires to assess body image specific to women with genital changes from pelvic organ prolapse. The purpose of this study was to assess implementation of a body image questionnaire in women with pelvic organ prolapse. The Vaginal Changes Sexual and Body Esteem Scale showed utility and potential for demonstrating change in body image after prolapse surgery.

  9. Normal Vulvovaginal, Perineal, and Pelvic Anatomy with Reconstructive Considerations

    2011-01-01

    A thorough insight into the female genital anatomy is crucial for understanding and performing pelvic reconstructive procedures. The intimate relationship between the genitalia and the muscles, ligaments, and fascia that provide support is complex, but critical to restore during surgery for correction of prolapse or aesthetic reasons. The external female genitalia include the mons pubis, labia majora and minora, clitoris, vestibule with glands, perineal body, and the muscles and fascia surrounding these structures. Through the perineal membrane and the perineal body, these superficial vulvar structures are structurally related to the deep pelvic muscle levator ani with its fascia. The levator ani forms the pelvic floor with the coccygeus muscle and provides vital support to all the pelvic organs and stability to the perineum. The internal female genital organs include the vagina, cervix, uterus, tubes, and ovaries with their visceral fascia. The visceral fascia also called the endopelvic fascia, surrounds the pelvic organs and connects them to the pelvic walls. It is continuous with the paraurethral and paravaginal fascia, which is attached to the perineal membrane. Thus, the internal and external genitalia are closely related to the muscles and fascia, and work as one functioning unit. PMID:22547969

    2015-12-01

    The purpose of this study was to investigate whether pelvic stabilization affects multifidus (MF) and iliocostalis lumborum (IL) muscle activities during dynamic extension exercise. Nine males (age, 25.1±6.3 yr; height, 176.6±2.4 cm; body mass, 74.9±6.7 kg) performed an isometric lumbar extension strength test and dynamic exercise in an upright seated position with or without pelvic stabilization. The electromyography and muscle strength of the MF and IL muscles were measured when the subjects performed the isometric lumbar extension strength test at the trunk angle 110°, 146°, and 182°. In addition, the trunk extensor muscle activities were measured using 50% muscle strength of maximum isometric strength during a dynamic trunk extension exercise. The MF and IL muscle activities were significantly higher at 110°, 146°, and 182° with pelvic stabilization than that without pelvic stabilization during the isometric lumbar extension strength test (Plumbar extension exercise with pelvic stabilization may be more effective for MF and IL muscle activity compared to that without pelvic stabilization.

    2013-07-01

    Full Text Available An Alaskan Malamute (2-year-old, castrated male, 41kg was referred with bilateral hind limb lameness. The dog had a history of a bilateral triple pelvic osteotomy (TPO to correct hip dysplasia one year previously, a surgery that was unsuccessful. On physical examination, pain and crepitus were noted in both hip joints. There was hip joint subluxation and mild degenerative changes bilaterally seen by radiograph. A Zurich cementless total hip replacement (ZCTHR was planned for the right hind limb. After a craniolateral approach, an acetabular cup and a cementless femoral stem were implanted. The femoral head was placed in the femoral stem, and the prosthetic joint was then reduced. At a 9 month postoperative checkup, there was no pain on palpation or manipulation of the right pelvic limb, and the range of motion was within normal limits. On radiological examination, there was no implant loosening. The ZCTHR can thus be applied in a failed TPO patient as a revision surgery.

  14. Pelvic belt effects on pelvic morphometry, muscle activity and body balance in patients with sacroiliac joint dysfunction.

    Directory of Open Access Journals (Sweden)

    Odette Soisson

    Full Text Available The sacroiliac joint (SIJ is frequently involved in low back and pelvic girdle pain. However, morphometrical and functional characteristics related to SIJ pain are poorly defined. Pelvic belts represent one treatment option, but evidence still lacks as to their pain-reducing effects and the mechanisms involved. Addressing these two issues, this case-controlled study compares morphometric, functional and clinical data in SIJ patients and healthy controls and evaluates the effects of short-term pelvic belt application.Morphometric and functional data pertaining to pelvic belt effects were compared in 17 SIJ patients and 17 controls. Lumbar spine and pelvis morphometries were obtained from 3T magnetic resonance imaging. Functional electromyography data of pelvis and leg muscles and center of pressure excursions were measured in one-leg stance. The numerical rating scale was used to evaluate immediate pain-reducing effects.Pelvic morphometry was largely unaltered in SIJ patients and also by pelvic belt application. The angle of lumbar lateral flexion was significantly larger in SIJ patients without belt application. Muscle activity and center of pressure were unaffected by SIJ pain or by belt application in one-leg stance. Nine of 17 patients reported decreased pain intensities under moderate belt application, four reported no change and four reported increased pain intensity. For the entire population investigated here, this qualitative description was not confirmed on a statistical significant level.Minute changes were observed in the alignment of the lumbar spine in the frontal plane in SIJ patients. The potential pain-decreasing effects of pelvic belts could not be attributed to altered muscle activity, pelvic morphometry or body balance in a static short-term application. Long-term belt effects will therefore be of prospective interest.

  15. Posterior-anterior weight-bearing radiograph in 15 knee flexion in medial osteoarthritis

    International Nuclear Information System (INIS)

    To evaluate the degree of knee flexion at which: (1) degenerative joint space narrowing is best seen, (2) the tibial plateau is best visualized and (3) the tibiofemoral angle is most correct, in order to assess the degree of flexion in the anteroposterior radiographic view that is most useful for assessing medial compartment osteoarthritis (OA) of the knee.Design and patients. We compared the conventional extended view of the knee and views at 15 , 30 , and 45 of flexion with respect to joint space narrowing, alignment of the medial tibial plateau (MTP), and tibiofemoral angles in 113 knees of 95 patients with medial osteoarthritis of the knee (22 men, 73 women; mean age 67 years).Results. At the midpoint and the narrowest point of the medial compartment, joint space narrowing values at 15 , 30 , and 45 of flexion of the knee were smaller than that of the conventional extended view. Superimposition of the margins of the tibial plateau was satisfactory in 12% of patients in the conventional extended view, in 36% at 15 of flexion, in 20% at 30 of flexion, and in 19% at 45 of flexion of the knee. When the knee was at 15 of flexion there was a smaller difference in the tibiofemoral angle, in comparison with the knee extended, than was the case at 30 and 45 of flexion in patients with medial OA.Conclusion. A posteroanterior view with 15 of flexion of the knee was able to detect joint space narrowing accurately, to achieve good alignment of the MTP in the medial compartment, and to reduce the difference in tibiofemoral angle compared with a view of the knee in conventional extension, and may be an alternative view in cases of medial OA of the knee.

    Purpose: Optimal treatment with radiation for metastatic lymphadenopathy in locally advanced cervical cancer remains controversial. We investigated the clinical dose response threshold for pelvic and para-aortic lymph node boost using radiographic imaging and clinical outcomes. Methods and Materials: Between 2007 and 2011, 68 patients were treated for locally advanced cervical cancer; 40 patients had clinically involved pelvic and/or para-aortic lymph nodes. Computed tomography (CT) or 18F-labeled fluorodeoxyglucose-positron emission tomography scans obtained pre- and postchemoradiation for 18 patients were reviewed to assess therapeutic radiographic response of individual lymph nodes. External beam boost doses to involved nodes were compared to treatment response, assessed by change in size of lymph nodes by short axis and change in standard uptake value (SUV). Patterns of failure, time to recurrence, overall survival (OS), and disease-free survival (DFS) were determined. Results: Sixty-four lymph nodes suspicious for metastatic involvement were identified. Radiation boost doses ranged from 0 to 15 Gy, with a mean total dose of 52.3 Gy. Pelvic lymph nodes were treated with a slightly higher dose than para-aortic lymph nodes: mean 55.3 Gy versus 51.7 Gy, respectively. There was no correlation between dose delivered and change in size of lymph nodes along the short axis. All lymph nodes underwent a decrease in SUV with a complete resolution of abnormal uptake observed in 68%. Decrease in SUV was significantly greater for lymph nodes treated with ≥54 Gy compared to those treated with <54 Gy (P=.006). Median follow-up was 18.7 months. At 2 years, OS and DFS for the entire cohort were 78% and 50%, respectively. Locoregional control at 2 years was 84%. Conclusions: A biologic response, as measured by the change in SUV for metastatic lymph nodes, was observed at a dose threshold of 54 Gy. We recommend that involved lymph nodes be treated to this minimum dose.

  18. Retention of anatomy knowledge by student radiographers

    International Nuclear Information System (INIS)

    Introduction: Anatomy has long been regarded as an integral part of the core curriculum. However, anecdotal evidence suggests that long-term retention of anatomy knowledge may be deficient. This study aims to evidence whether student radiographers demonstrate the same level of knowledge of anatomy after a period of time has elapsed and to correlate to approaches to learning and studying. Methodology: A repeated measures design was utilised to measure retention of anatomy knowledge for both MCQs and short-response answers to a Practical Radiographic Anatomy Examination; alpha value p < 0.05. Fifty-one students from levels 2 and 3 were retested after a time lapse of 10 and 22 months respectively. The students were not aware that their knowledge was being retested. Approaches to learning and studying were measured using the ASSIST inventory. Results: Statistical analysis found no difference in performance on MCQ assessment, in either the combined sample or levels 2 and 3 separately, from baseline to retention occasions; average retention rate being 99%. However, a statistical difference in performance on PRAE assessment was found, with level 2 experiencing a larger reduction in scores; retention rate of 67% compared to level 3 at 77%. The students perceived themselves to be principally strategic in their approach to learning and studying but no strong relationships were found when correlated to test scores. Conclusion: The student radiographers in this study demonstrated varied anatomy retention rates dependent on assessment method employed and time interval that had elapsed. It is recommended that diverse teaching and assessment strategies are adopted to encourage a deeper approach to learning and studying.

    Ribs and clavicles in posterior-anterior (PA) digital chest radiographs often overlap with lung abnormalities such as nodules, and cause missing of these abnormalities, it is therefore necessary to remove or reduce the ribs in chest radiographs. The purpose of this study was to develop a fully automated algorithm to segment ribs within lung area in digital radiography (DR) for removal of the ribs. The rib segmentation algorithm consists of three steps. Firstly, a radiograph was pre-processed for contrast adjustment and noise removal; second, generalized Hough transform was employed to localize the lower boundary of the ribs. In the third step, a novel bilateral dynamic programming algorithm was used to accurately segment the upper and lower boundaries of ribs simultaneously. The width of the ribs and the smoothness of the rib boundaries were incorporated in the cost function of the bilateral dynamic programming for obtaining consistent results for the upper and lower boundaries. Our database consisted of 93 DR images, including, respectively, 23 and 70 images acquired with a DR system from Shanghai United-Imaging Healthcare Co. and from GE Healthcare Co. The rib localization algorithm achieved a sensitivity of 98.2% with 0.1 false positives per image. The accuracy of the detected ribs was further evaluated subjectively in 3 levels: "1", good; "2", acceptable; "3", poor. The percentages of good, acceptable, and poor segmentation results were 91.1%, 7.2%, and 1.7%, respectively. Our algorithm can obtain good segmentation results for ribs in chest radiography and would be useful for rib reduction in our future study.

  1. On being dyslexic: Student radiographers' perspectives

    International Nuclear Information System (INIS)

    The purpose of this paper was to provide an insight into life as a dyslexic student radiographer, identify barriers and risks in clinical training, and develop recommendations for the support of students with dyslexia. The paucity of research into dyslexia within the radiography profession is worrying, with attention focused only on the support provided by Higher Education Institutions (HEI) or inferences drawn from the experiences of other healthcare students. The impact and significance of dyslexia for student radiographers in clinical practice has never been investigated. Results: On a self-reporting scale of clinical tasks there was little or no difference between dyslexic students and non-dyslexics. Some minor traits commonly associated with dyslexics were also reported by students with no learning disabilities and an inclusion support plan for all students was advocated. In-depth interviews of 10 student radiographers revealed six distinct themes of visualising the disability, self-protection, strengths and talents, time, the badge of disability and adjustments and support. Like other healthcare students, some radiography students reported significant difficulties and prejudices and very little structured support in the clinical environment. Despite the Special Educational Needs and Disability Act being in place for several years, the support in clinical departments fell significantly short of that provided in the universities. The dyslexic students took extra responsibility for their own learning and some had developed complex coping strategies to overcome any difficulties. Conclusion: Several inclusive recommendations were developed as a result of this study that could be used to support all students on clinical placement.

Sotomayor Obstetrics and Gynecology Hospital, Guayaquil, EcuadorAbstract: Female genital Actinomyces infection is relatively rare, although strongly related to long-lasting intrauterine contraceptive device (IUD application. An infective pathway has been postulated extending upward from the female perineum to the vagina and cervix. The traumatic effect of the device and a prior infection may contribute to the Actinomyces infection in the female genitalia. This disease is characterized by local swelling, suppuration, abscess formation, tissue fibrosis, tubal-ovarian mass and fistula formation. The infection spreads by contiguity often mimicking the characteristics of a malignant neoplastic process. Currently there is no consensus regarding diagnosis and screening tests, although there seems to be agreement in relation to IUD type, duration, and sexual behavior as major risk factors.Keywords: contraception, intrauterine contraceptive device, pelvic actinomycosis, sexuality

    Full Text Available Aims: The aim of the study was to measure airway patency objectively during dexmedetomidine sedation under radiographic guidance in spontaneously breathing pediatric patients scheduled for cardiac catheterization procedures. Subjects and Methods: Thirty-five patients in the age group 5-10 years scheduled for cardiac catheterization procedures were enrolled. All study patients were given loading dose of dexmedetomidine at 1 mg/kg/min for 10 min and then maintenance dose of 1.5 mg/kg/h. Radiographic airway patency was assessed at the start of infusion (0 min and after 30 min. Antero-posterior (AP diameters were measured manually at the nasopharyngeal and retroglossal levels. Dynamic change in airway between inspiration and expiration was considered a measure of airway collapsibility. Patients were monitored for hemodynamics, recovery time and complications. Statistical Analysis: Student paired t-test was used for data analysis. P < 0.05 was considered significant. Results: Minimum and maximum AP diameters were compared at 0 and 30 min. Nasopharyngeal level showed significant reduction in the minimum (6.27 ± 1.09 vs. 4.26 ± 1.03, P < 0.0001 and maximum (6.51 ± 1.14 vs. 5.99 ± 1.03, P < 0.0001 diameters. Similarly retroglossal level showed significant reduction in the minimum (6.98 ± 1.09 vs. 5.27 ± 1.15, P < 0.0001 and maximum (7.49 ± 1.22 vs. 6.92 ± 1.12, P < 0.0003 diameters. The degree of collapsibility was greater at 30 min than baseline ( P < 0.0001. There was a significant decrease in heart rate ( P < 0.0001, and the average recovery time was 39.86 ± 12.22 min. Conclusion: Even though airway patency was maintained in all children sedated with dexmedetomidine, there were significant reductions in the upper airway dimensions measured, so all precautions to manage the airway failure should be taken.

    Full Text Available Abstract Background There are several clinical and radiological methods available to classify foot posture in research, however there is no clear strategy for selecting the most appropriate measurements. Therefore, the aim of this study was to develop a foot screening protocol to distinguish between participants with normal- and flat-arched feet who would then subsequently be recruited into a series of laboratory-based gait studies. Methods The foot posture of ninety-one asymptomatic young adults was assessed using two clinical measurements (normalised navicular height and arch index and four radiological measurements taken from antero-posterior and lateral x-rays (talus-second metatarsal angle, talo-navicular coverage angle, calcaneal inclination angle and calcaneal-first metatarsal angle. Normative foot posture values were taken from the literature and used to recruit participants with normal-arched feet. Data from these participants were subsequently used to define the boundary between normal- and flat-arched feet. This information was then used to recruit participants with flat-arched feet. The relationship between the clinical and radiographic measures of foot posture was also explored. Results Thirty-two participants were recruited to the normal-arched study, 31 qualified for the flat-arched study and 28 participants were classified as having neither normal- or flat-arched feet and were not suitable for either study. The values obtained from the two clinical and four radiological measurements established two clearly defined foot posture groups. Correlations among clinical and radiological measures were significant (p r = 0.24 to 0.70. Interestingly, the clinical measures were more strongly associated with the radiographic angles obtained from the lateral view. Conclusion This foot screening protocol provides a coherent strategy for researchers planning to recruit participants with normal- and flat-arched feet. However, further research is

    The purpose of the present study was to compare the intra- and interobserver reliability of two different measurement methods for volar angulation of the 5th metacarpal (MC) in an attempt to establish a new standard measurement method to reduce interobserver discrepancies for therapeutic decisions. Twenty patients with subcapital fractures of the 5th MC were radiologically investigated. Imaging consisted of a radiographs in antero-posterior and precise lateral view in addition to a CT scan of the 5th MC. Measurement of volar angulation was accomplished using the conventional and the shaft articular surface (SAS) method. The measurements of five investigators were exported to a spreadsheet for statistical analysis to evaluate the intra-and interobserver reliability. The conventional technique showed large differences among the investigators and poor interobserver reliability (W = 0.328 and 0.307) both at injury (p = 0.001) and at follow-up (p = 0.189). The intraobserver concordance of all investigators showed better results with the SAS than with the conventional technique. With the SAS technique, no statistically significant difference among the investigators could be detected at either the time of injury (p = 0.418) or at follow-up (p = 0.526) with excellent interobserver reliability (W = 0.051 and W = 0.041). Evaluation of volar angulation at follow-up using CT scans did not show any statistically significant difference between the techniques with better correlation among the observers with the SAS technique (p = 0.838). The interobserver correlation of volar angulation with lateral radiographs using the conventional technique was insufficient. Therefore, we recommend the use of the novel SAS technique as standardized measurement method which showed higher accuracy and interobserver reliability in order to facilitate the choice of adequate treatment option.

    Full Text Available ABSTRACT: Radiographs are an irreplaceable diagnostic tool, es pecially in dealing with dentofacial hard tissues. Guidelines like the ALARA require professionals to limit the number of radiographs prescribed to patient, thereby minimizing radiation dose. On the other hand, for prosthetic evaluation, a latest radiograph has the po tential to uncover new findings that can alter the treatment planning sequence or affect the outcome of the planned treatment. This review article discusses ten such radiographs. The s ignificant findings in each radiograph have been highlighted and treatment protocols tailored t o the same. The aim of this article is to help the reader adopt a meticulous approach and a keen eye for detecting problems, and emphasizes the efficacy of radiographs in patient evaluation for restorative care

    International Nuclear Information System (INIS)

    Two new stress-radiographic positioning techniques, namely 60 deg and 90 deg stress techniques, were introduced for quantifying hip joint laxity in dogs. The comparative characteristics and efficiency of these new techniques with angled hindlimbs were evaluated relative to the standard hip-extended radiographic technique. Forty, healthy, mongrel dogs with normal hip joint conformation were anesthetized and placed in dorsal recumbency before 3 radiograhps of the standard, 60 deg , and 90 deg stress techniques were taken. For the 60 deg stress technique, hindlimbs were extended in parallel to each other at 60 deg angled to the table top and stifles were slightly rotated inward, femoral heads were manually pushed in a craniodorsal direction during exposure. For the 90 deg stress technique, femurs were positioned perpendicular to the table top, stifles were 90 deg flexed and adducted and femoral heads were manually pushed in a craniodorsal direction during exposure. The subluxation index (SI) and dorsolateral subluxation score (DLS score) were calculated from 3 radiographic views for both hip joints to quantitate the relative degree of joint laxity. Results of the study indicated that the 60 deg (SI = 0.20+-0.045, DLS score = 62.5+-7.96 percent) and 90 deg (SI = 0.23+-0.044, DLS score = 61.2+-9.47 percent) stress-radiographs yielded significantly (p0.001) higher degree of hip joint laxity than the standard technique (SI)

    The aim of the present investigation was to study prevalence of low back pain, pelvic girdle pain (PGP) and pelvic floor disorders during pregnancy and after childbirth in elite athletes. A postal questionnaire was sent to all elite athletes who had given birth registered with The Norwegian Olympic Committee and Confederation of Sports (n=40). Eighty age-matched women served as the control group. The response rates were 77.5% and 57.5% in the elite athletes and control groups, respectively. There were no significant differences in the prevalence of low back and PGP, urinary or fecal incontinence among elite athletes and controls at any time point. The prevalence of low back pain without radiation to the leg in elite athletes was 25.8%, 18.5%, 9.7% and 29% the year before pregnancy, during pregnancy, 6 weeks postpartum and at the time of completing the questionnaire, respectively. The prevalence of PGP was 0, 29.6%, 12.9% and 19.4%. Prevalence of stress urinary incontinence was 12.9%, 18.5%, 29% and 35.5%. None of the elite athletes had fecal incontinence at any time point. There were no differences in mode of delivery or birthweight between elite athletes and controls. The elite athletes had a significantly lower body mass index at 6 weeks postpartum and at present compared with the control group.

    Poor lateral flexor muscle strength can be an important source of lumbar/thoracic back pain in women. The purpose of this study was to evaluate pelvic stabilization (PS) and no pelvic stabilization (NoPS) lateral flexion strength exercise training on the development of isolated right and left lateral flexion strength. Isometric torque of the isolated right and left lateral flexion muscles was measured at two positions (0° and 30° opposed angle range of motion) on 42 healthy women before and after 8 weeks of PS and NoPS lateral flexion strength exercise training. Subjects were assigned in three groups, the first (n=14) trained 3 times/week with PS lateral flexion strength exercise, the second (n=14) trained 3 times/week with NoPS lateral flexion strength exercise and the third (control, n=14) did not train. Post training isometric strength values describing PS and NoPS lateral flexion strength improved in greater extent for the PS lateral flexion strength exercise group and in lesser extent for the NoPS lateral flexion strength exercise group, in both angles (p<0.05) relative to controls. These data indicate that the most effective way of training the spine lateral flexion muscles is PS lateral flexion strength exercises; NoPS lateral flexion strength exercises can be an effective way of training for the spine lateral flexion muscles, if there is no access to PS lateral flexion strength training machines.

  15. Simulation of neutron radiograph images at the Neutron Radiography Reactor

    International Nuclear Information System (INIS)

    Highlights: ► The project developed a method to simulate neutron radiograph images. ► A characteristic curve relation activation foil activity to film optical density. ► The simulation uses the characteristic curve to predict radiographic images. ► Radiographs of a polyethylene step block validate the methodology. - Abstract: The ability to accurately simulate potential radiographic images produced by a radiographic facility can improve the facility’s ability to design experiments and evaluate images. The image simulation methods detailed in this paper predict the radiographic image of an object based on the foil reaction rate data obtained by placing a model of the object in front of the image plane in a Monte Carlo beamline model. The image simulation method utilizes a characteristic curve relating foil activity to optical density for the film and foil combination in use at the Neutron Radiography Reactor. The simulation validation compared a radiograph of a polyethylene step block to a simulated radiograph of the same step block. The simulation accurately predicts the optical density in each region of a radiograph of the step block. The simulated radiograph predicts the average optical density of the actual radiograph more accurately for the thinner steps, resulting in step averaged optical density differences between the actual and simulated images of −11.6% for the thinnest step versus a difference of −34.7% for the thickest step, possibly due to the greater accuracy of the higher optical density region of the characteristic curve. Applying the scanner calibration curve to the calculated optical density values decreases the difference between the actual radiograph pixel values and the simulated pixel values for each step except the thinnest step. The step averaged differences between the corrected and actual images increase from −11.6% to −17.0% for the thinnest step and decrease from −34.7% to +7.7% for the thickest step after the

    To establish regression models for age estimation from the combination of the ossification of iliac crest and ischial tuberosity. One thousand three hundred and seventy-nine conventional pelvic radiographs at the West China Hospital of Sichuan University between January 2010 and June 2012 were evaluated retrospectively. The receiver operating characteristic analysis was performed to measure the value of estimation of 18 years of age with the classification scheme for the iliac crest and ischial tuberosity. Regression analysis was performed, and formulas for calculating approximate chronological age according to the combination developmental status of the ossification for the iliac crest and ischial tuberosity were developed. The areas under the receiver operating characteristic (ROC) curves were above 0.9 (p systems, and the cubic regression model was found to have the highest R-square value (R (2) = 0.744 for female and R (2) = 0.753 for male). The present classification scheme for apophyseal iliac crest ossification and the ischial tuberosity may be used for age estimation.

    Visualising volumetric medical images such as computed tomography and magnetic resonance imaging (MRI) on picture archiving and communication systems (PACS) clients is often achieved by image browsing in sagittal, coronal or axial views or three-dimensional (3D) rendering. This latter technique requires fine thresholding for MRI. On the other hand, computing virtual radiograph images, also referred to as digitally reconstructed radiographs (DRR), provides in a single two-dimensional (2D) image a complete overview of the 3D data. It appears therefore as a powerful alternative for MRI visualisation and preview in PACS. This study describes a method to compute DRR from T1-weighted MRI. After segmentation of the background, a histogram distribution analysis is performed and each foreground MRI voxel is labeled as one of three tissues: cortical bone, also known as principal absorber of the X-rays, muscle and fat. An intensity level is attributed to each voxel according to the Hounsfield scale, linearly related to the X-ray attenuation coefficient. Each DRR pixel is computed as the accumulation of the new intensities of the MRI dataset along the corresponding X-ray. The method has been tested on 16 T1-weighted MRI sets. Anterior-posterior and lateral DRR have been computed with reasonable qualities and avoiding any manual tissue segmentations. This proof-of-concept holds for research application for use in clinical PACS.

    Radiographic films produce different densities and contrast when processor changes occur, and the magnitude and rate of change vary with film type. The ability to detect and interpret the clinical importance of film density changes may depend on the method of sensitometry used. The characteristics of several medical radiographic films and various sensitometers were examined under three sensitometric variations and five processing variations. Of all variations used, only exposure with a single-versus a double-sided sensitometer caused a film type to have a marked different response. The results indicate that mismatching the sensitometer spectral output with the spectral sensitivity of the film in most cases does not affect the density changes of the film. The fact that a few films may be sensitive to differences in spectral content of the exposing light and dual- versus single-sided exposure and that only a limited number of film types were tested, however, leads to the prudent conclusion that the exposure conditions for quality control purposes should match clinical exposure conditions as closely as possible.

    Condylar hyperplasia is a self-limiting condition characterized by a slowly progressing, enlargement of the mandible that results in facial asymmetry and a cross bite maloccusion. The facial asymmetry, open bite or cross bite, and radio graphic evidence of an enlarged condyle confirm the diagnosis of condylar hyperplasia. The etiology of the condition is unknown. This condition usually first becomes apparent during the second decade of life, when one condyle continues to grow while the other is no longer active. Radiographically, the condyle may appear enlarged or the neck of the condyle may be elongated or both may occur, sometimes, however, no raiographically demonstrable condylar abnormality will be noted. Surgical correction with subcondylar osteotomy is the treatment choice. We have observed two cases of condylar hyperplsia occurred in the left mandibular condyle of 24-year-old and 35-year- old women. We obtained that two cases were shown the followed results; 1. Clinically, both cases was unilaterally developed on C/C area, with temporomandibular disorders and pain, facial asymmetry and malcclusion. 2. Radiographically, hyperplastic mass confined to the condyle. 3. Histopathologically, these cases shown increased hypertrophic region in parts, and lamellated bone wit h irregular trabeculae.

    Full Text Available The ankle joint is the most frequently injured joint in adults. Decisions on management are usually based on clinical examination and interpretation of the x-rays. Stability of the ankle mortise relies on the configuration of the osseous structures and the ligaments. A basic radiographic examination consists of a mortise-view and a lateral view. Some add the AP-view. The Mortise view is an AP-view with 15-25 degrees endorotation of the foot. "nThe view clearly demonstrates both lateral and medial joint spaces. On a true AP-view the talus overlaps a portion of the lateral malleolus obscuring the lateral aspect of the ankle joint. However, the AP-view will give you an extra view on both malleoli from a different angle. The lateral radiograph of the ankle should include the base of the fifth metatarsal because of the frequency of fractures at this side that clinically mimic a fracture of the ankle.

    The purpose of this study was to accurately analyze the radiographic characteristics of dentigerous cyst (DC) with multiplanar images of cone beam computed tomography (CBCT). Thirty eight radiographically and histopathologically proven cases of DCs were analyzed with panoramic radiograph and CBCT, retrospectively. The radiographic CT pattern, symmetry of radiolucency around the unerupted tooth crown, ratio of long length to short length, degree of cortical bone alternation, effects on adjacent tooth, and cyst size were analyzed. Relative frequencies of these radiographic features were evaluated. In order to compare the CBCT features of DC with those of odontogenic keratocyst (OKC), 9 cases of OKCs were analyzed with the same method radiographically. DCs consisted of thirty unilocular cases (79.0%), seven lobulated cases (18.4%) and one multilocular case (2.6%). Eight were asymmetric (21.0%) and thirty were symmetric (79.0%). Maxillary DC showed rounder shape than mandibular DC (L/S ratio; maxilla 1.32, mandible 1.67). Alternations of lingual cortical bone (14 cases, 48.2%) were more frequent than those of buccal side (7 cases, 24.1%). CBCT images of DC showed definite root resorption and bucco-lingual tooth displacement. These findings were hardly observed on panoramic radiographs of DCs. Comparison of CBCT features of DC with those of OKC showed several different features. CBCT images of DC showed various characteristic radiographic features. Therefore, CBCT can be helpful for the diagnosis of DC radiographically.

    This paper presents study of computer analysis of the 1980 ILO standard chest radiographs of pneumoconiosis. Algorithms developed for detection of individual small rounded and irregular opacities have been experimented and evaluated on these standard radiographs. The density, shape, and size distribution of the detected objects in the lung field, in spite of false positives, can be used as indicators for the beginning of pneumoconiosis. This approach is potentially useful in computer-assisted screening and early detection process where the annual chest radiograph of each worker is compared with his (her) own normal radiograph obtained previously.

    Highlights: • Pelvic radiographs with speed class 400 and 800 in follow-up of hip arthroplasty were compared. • Radiographs with reduced dose (800) were not inferior to those with standard dose (400). • We recommend speed class 800 as new reference parameter in these examinations. - Abstract: Objective: Digital plain radiographs of the pelvis are frequently performed in follow-up examinations of patients who received total hip arthroplasty (THA) or osteosynthesis (OS). Thus, the purpose was to reduce the radiation dose and to determine objective quality control criteria to ensure accurate assessment. Materials and methods: Institutional review board approval was obtained. In this prospective randomized study, 289 patients underwent X-ray examination of the pelvis as follow up after receiving THA or OS with standard and reduced dose. The evaluation of the plain radiographs was conducted using the following criteria: bone–implant interface, implant–implant discrimination, implant–surface character and periarticular heterotopic ossification. Two radiologists evaluated these criteria using a score ranging from 1 (definitely assessable) to 4 (not assessable). If a single criterion had been evaluated with a score of 3 or more or more than 2 criteria with 2 points, the radiograph was scored as “not assessable“. The study was designed as non-inferiority-trial. Results: Seven (2.4%) examined X-rays were scored as not assessable. There was no statistical inferiority between the examinations with standard (0.365 mSv) or reduced dose (0.211 mSv). Reduced dose only led to limitations in the evaluation of ceramic components with low clinical impact in most scenarios. Conclusion: Plain radiography of the pelvis in patients with THA or OS can be performed with a dose reduction of about 42% without a loss of important information. The obtained quality control criteria were clinically applicable.

    Background Patients with pelvic fractures are often treated in hospitals without the capacity to implement an open reduction internal fixation (ORIF).This often leads to pelvic malunion in patients with unstable pelvic fracture,shock or even death due to uncontrollable pelvic hemorrhage and unstable hemodynamics.This study explored the role of early external fixation (within 7 days) for patients with unstable pelvic fractures.Methods A retrospective analysis was conducted on 32 patients with unstable pelvic fractures treated with early external fixation from January 2005 to January 2010 (file type B:18 cases; C:14 cases).The study comprised 28 males and 4 females,with a mean age of (32±8) years (range,21-56 years).Of these patients,22 were treated with emergency pelvic external fixation and 10 were treated with external fixation within 1-7 days.Fifteen cases suffered traumatic hemorrhagic shock.A statistical analysis was conducted to compare fluid infusion and blood transfusion volumes within the first 24 hours of these shock patients with another cohort of patients treated without early external fixation from January 1993 to January 1998.Results The average follow-up was (34.7±14.6) months (range,6-66 months).Six to eight weeks after external fixation,patients could walk with crutches; by 12 weeks,external fixation was removed and all fractures had healed.Seven patients presented with sequelae,including 3 patients with long-term lumbosacral pain,3 patients with erectile dysfunction and 1 patient with Morel-Lavallee lesion and other complications.The 15 shock patients in this study (2005-2010 group) required significantly lower volumes of fluid infusion and blood transfusion (Pfluid=0.000;Ptransfusion=0.000) as compared to the 1993-1998 cohort.Conclusions The early application of external fixation in unstable pelvic fracture patients positively affects hemodynamic stability,with outstanding efficacy as a final fixation option for unstable pelvic fractures.

  7. Referred pain patterns provoked on intra-pelvic structures among women with and without chronic pelvic pain: a descriptive study.

    Thomas Torstensson

    Full Text Available To describe referred pain patterns provoked from intra-pelvic structures in women with chronic pelvic pain (CPP persisting after childbirth with the purpose to improve diagnostics and give implications for treatment.In this descriptive and comparative study 36 parous women with CPP were recruited from a physiotherapy department waiting list and by advertisements in newspapers. A control group of 29 parous women without CPP was consecutively assessed for eligibility from a midwifery surgery. Inclusion criterion for CPP was: moderate pain in the sacral region persisting at least six months after childbirth confirmed by pelvic pain provocation tests. Exclusion criteria in groups with and without CPP were: persistent back or pelvic pain with onset prior to pregnancy, previous back surgery and positive neurological signs. Pain was provoked by palpation of 13 predetermined intra-pelvic anatomical landmarks. The referred pain distribution was expressed in pain drawings and described in pain maps and calculated referred pain areas.Pain provoked by palpation of the posterior intra-pelvic landmarks was mostly referred to the sacral region and pain provoked by palpation of the ischial and pubic bones was mostly referred to the groin and pubic regions, with or without pain referred down the ipsilateral leg. The average pain distribution area provoked by palpation of all 13 anatomical landmarks was 30.3 mm² (19.2 to 53.7 in women with CPP as compared to 3.2 mm² (1.0 to 5.1 in women without CPP, p< 0.0001.Referred pain patterns provoked from intra-pelvic landmarks in women with CPP are consistent with sclerotomal sensory innervation. Magnification of referred pain patterns indicates allodynia and central sensitization. The results suggest that pain mapping can be used to evaluate and confirm the pain experience among women with CPP and contribute to diagnosis.

  8. Expression of estrogen receptors in the pelvic floor of pre- and post-menopausal women presenting pelvic organ prolapse

    Full Text Available The precise role of estrogen in the pathogenesis of pelvic organ prolapse (POP is still unclear, while the results concerning the effect of selective estrogen receptor modulators on pelvic organ prolapse are contradictory. Our aim was to test whether alteration in the expression of estrogen receptors in the pelvic floor of preand post-menopausal women is related to genital prolapse status. The mRNA levels of ERα and ERβ in 60 biopsy specimens were measured. Significantly higher expression of ERα and higher ERα/ERβ ratio were demonstrated in post-menopausal women compared to pre-menopausal women. Higher expression of ERα and higher ERα/ERβ ratio were detected in all studied groups with POP, thus it did not reach significance in the post-menopausal group. Pre-menopausal and post-menopausal women presenting pelvic organ prolapse had no difference in the ERα expression. Our preliminary study may indicate that pelvic organ prolapse is associated with higher expression of ERα/ERβ in the pelvic floor of both pre- and post-menopausal women; thus not reaching statistical significance in the post-menopausal women was probably due to the group’s size. We believe that the inevitable changes in the estrogen receptor expression over women’s different lifetimes may affect the risk of genital prolapse progression, and might contribute to the further search for appropriate selective estrogen receptor modulators as a treatment for women with pelvic organ prolapse.

    Full Text Available Background/Objective: Ultrasonography has replaced roentgenography in recent obstetric practice. X-ray pelvimetry in the management of vaginal delivery in patients with previous cesarean section is the only exception in some centers. There has been no report of the prevalence of four major pelvic types in Iranian females before this study."nPatients and Methods: In this study, we evaluated the types of pelvis and pelvic measurements of 185 adult female patients in four different regional municipalities of Mashhad. AP pelvic x-ray was performed for all the patients. All images were reported by a radiologist."nResults: Gynecoid pelvis was the most common pelvic type (88.6% followed by platyploid (7.6%, android (2.7% and anthropoid (1.1%. The results including the types of pelvis and the measurements had significant differences with previous studies in western countries. There were no significant differences in the prevalence of pelvic types between different imaging centers, different age groups and nulliparous vs. parous patients. "nConclusion: The prevalence of pelvic types depends on human race but it does not appear to be influenced by parity or age.

    A child's body size is not accurately reflected by volume CT dose index (CTDI{sub vol}) and dose-length product (DLP). Size-specific dose estimation (SSDE) was introduced recently as a new index of radiation dose. However, it has not yet been established as a diagnostic reference level (DRL). To calculate the SSDE of abdominal/pelvic CT and compare the SSDE with CTDI{sub vol}. To calculate the DRLs of CTDI{sub vol} and SSDE. Our hypotheses are: SSDE values will be greater than CTDI{sub vol}, and our DRL will be smaller than the known DRLs of other countries. The CTDI{sub vol} and DLP of 117 children who underwent abdominal/pelvic CT were collected retrospectively. The SSDE was calculated from the sum of the lateral and anteroposterior diameters. The relationships between body weight and effective diameter and between effective diameter and CTDI{sub vol}/SSDE were compared. Further, the local DRL was compared with the DRLs of other countries. Body weight and effective diameter and effective diameter and SSDE were positively correlated. In children ages 1, 5 and 10 years, the SSDE is closer to the exposure dose of CTDI{sub vol} for the 16-cm phantom, while in children ages 15 years, the SSDE falls between CTDI{sub vol} for the 16-cm phantom and that for the 32-cm phantom. The local DRL was lower than those of other countries. With SSDE, the radiation dose increased with increasing body weight. Since SSDE takes body size into account, it proved to be a useful indicator for estimating the exposure dose. (orig.)

    ABSTRACT Objective: The purpose of this study was to assess the importance of pelvic fractures in childhood by analyzing epidemiological characteristics and associated injuries. Methods: This is a retrospective study performed between 2002 and 2012 at two trauma referral centers in São Paulo. We identified 25 patients aged 16 years old or younger with pelvic fracture. Results: The main mechanism of trauma was traffic accident (80%), followed by fall from height (16%). At hospital admission, 92% had traumatic brain injury and 40% had hemodynamic instability. Besides pelvic fractures, 56% of the children had other associated injuries (genitourinary, abdominal, vascular, chest and neurological), and 79% of them required operative treatment. According to the Torode and Zieg classification, the majority of cases were types III and IV. Seventy-two percent of all pelvic fractures were treated by surgery; 52% involved external fixation and 20% involved open reduction and internal fixation. Conclusions: The pelvic fractures in childhood can be considered a marker for injury severity, because the associated injuries usually are severe, needing operative treatment and leading to a high mortality rate (12%).

  12. Radiologic imaging and percutaneous treatment of pelvic lymphocele

    International Nuclear Information System (INIS)

    Pelvic lymphocele, also known as lymphocyst, is a cystic structure caused by lymphatic injury usually secondary to pelvic lymphadenectomy and renal transplantation. Lymphoceles can cause morbidity and rarely mortality by compression of adjacent structures and infectious complications. This review discusses etiology and treatment options for pelvic lymphoceles including surgical and percutaneous methods with emphasis on percutaneous techniques particularly in conjunction with sclerotherapy. Percutaneous catheter drainage with sclerotherapy procedure with various sclerosing agents is described in detail. Ethanol, povidone-iodine, tetracycline, doxycycline, bleomycin, talc and fibrin glue can be used as sclerosing agents. Combination of sclerosing agents to percutaneous catheter drainage significantly improves success rate in the treatment of pelvic lymphoceles. Infected lymphoceles are usually treated solely with percutaneous catheter drainage. Percutaneous treatment can be tailored according to volume of lymphoceles. We generally prefer single session sclerotherapy and 1 day catheter drainage in lymphoceles less than 150 mL, and larger ones are treated by multi-session sclerotherapy until daily drainage decreases below 10 mL. Percutaneous treatment preferably with sclerotherapy should be considered as the first-line treatment modality for pelvic lymphoceles due to its effectiveness, widespread applicability on an outpatient basis, ease of procedure and low complication rate

    Pelvic floor disorders are highly prevalent in women of all ages and can greatly impair quality of life. Pelvic floor muscle training (PFMT) is a viable treatment option for several pelvic floor conditions including urinary incontinence and pelvic organ prolapse. PFMT is a program of therapy initiated by an experienced clinician (e.g., women's health or urology nurse practitioner (NP), physical therapist (PT)) that involves exercises for women with stress urinary incontinence (UI) and exercises combined with behavioral or conservative treatments (lifestyle changes, bladder training with urge suppression) for women with urgency or mixed UI. These exercise programs are more comprehensive than simple Kegel exercises. Despite evidence-based research indicating the efficacy and cost-effectiveness for treatment of urinary incontinence, PFMT is not commonly used as a first-line treatment in clinical practice in the USA (Abrams et al., 2012). This article will review PFMT for the treatment of UI and pelvic organ prolapse (POP) and theorize how this conservative therapy can be utilized more effectively in the USA. PMID:26757904

    Pelvic organ prolapse has afflicted women since the beginning of mankind. Even though we have been faced with this problem for so many centuries, we still have not found a way to overcome gravity and prevent prolapse. We continue to make efforts to manage prolapse, modifying our techniques based on burgeoning research. This knowledge helps us to avoid repetitive complications from surgery and to improve techniques to prevent recurrent prolapse. In addition, we are constantly adapting our methods depending on available technology. With an aging population, the demand for physicians and surgeons trained in management of pelvic organ prolapse will increase. The rapidly evolving literature on pelvic organ prolapse makes a comprehensive review difficult. However, based on the current literature, randomized controlled trials are needed to compare new prolapse repair techniques to traditional techniques. Physicians specializing in surgical management of pelvic organ prolapse will need to work together to complete quality clinical trials. The primary focus of this review will be on the recent research concerning the epidemiology, etiology, presenting symptoms, and diagnosis of pelvic organ prolapse. We will also discuss the different types of prolapse by compartments of the vagina in which they occur and how each of these types of prolapse can be managed. Finally, we will review recent literature evaluating surgical repairs using transvaginal mesh kits. PMID:18043574

  16. Utilization of Human-Like Pelvic Rotation for Running Robot

    2015-07-01

    Full Text Available The spring loaded inverted pendulum (SLIP is used to model human running. It is based on a characteristic feature of human running, in which the linear-spring-like motion of the standing leg is produced by the joint stiffness of the knee and ankle. Although this model is widely used in robotics, it does not include human-like pelvic motion. In this study, we show that the pelvis actually contributes to the increase in jumping force and absorption of landing impact. On the basis of this finding, we propose a new model, SLIP2 (spring loaded inverted pendulum with pelvis, to improve running in humanoid robots. The model is composed of a body mass, a pelvis, and leg springs, and, it can control its springs while running by use of pelvic movement in the frontal plane. To achieve running motions, we developed a running control system that includes a pelvic oscillation controller to attain control over jumping power and a landing placement controller to adjust the running speed. We also developed a new running robot by using the SLIP2 model and performed hopping and running experiments to evaluate the model. The developed robot could accomplish hopping motions only by pelvic movement. The results also established that the difference between the pelvic rotational phase and the oscillation phase of the vertical mass displacement affects the jumping force. In addition, the robot demonstrated the ability to run with a foot placement controller depending on the reference running speed.

    Full Text Available A normal motion and segmental interrelationship has been determined as a significant factor in normal function. Yet, the relationship between distal segments and pelvic alignment needs further investigation. The aim of this study was to investigate the interrelationship between distal and proximal lower extremity segments while standing and during induced feet hyperpronation. Changes in alignment of the pelvis and lower extremities were measured at a gait laboratory using the VICON 612 computerized motion analysis system. Thirty-five healthy volunteer subjects were recruited. Four randomized repeated-measure standing modes were used: standing directly on the floor and then on three wedges angled at 10°, 15° and 20° to induce bilateral hyperpronation for 20 seconds. A significant (p<0.05 bi-variate relationship was found between the anterior pelvic tilt and thigh internal rotation, in all four standing positions (.41≤r≤.46, in all p<0.014. A combined effect of rotational alignment between segments and the cumulative effect of foot hyperpronation on pelvic tilt revealed that only the shank significantly affected pelvic alignment, acting as a mediator between a foot and a thigh with the thigh having a crude significant effect on the pelvis. When internal rotation of the shank occurs, calcaneal eversion couples with thigh internal rotation and anterior pelvic tilt. It can be concluded that in response to induced hyperpronation, the shank is a pivotal segment in postural adjustment.

    The ultrasonography is a very useful diagnostic procedure in obstetric and gynecologic mass. So we analyzed total 153 cases of pelvic ultrasonogram with pathologic diagnoses. The results were as follows: 1. The ages of patients were distributed from 16 to 70 years-old, and the third decade was the most prevalent. 2. Of 153 cases, the ovarian masses were 85 cases, the tubal ones were 49 cases, and the uterine were 19 cases. 3. Of 85 ovarian masses, physiologic ovarian cysts were 44 cases, and cystic teratoma were 14 cases, Of 49 tubal masses, tubal pregnancies were 35 cases and the most prevalent. Of 19 uterine masses, leiomyomas were 11 cases and most prevalent. 4. Of 153 cases, the echo-complex masses were 103 cases, the cystic ones were 34 cases, and the solid ones were 19 cases. 5. The characteristic findings of frequent masses were as follows: (1) The physiologic ovarian cysts were 44 cases, and show mainly cystic or pure cystic masses in 42 cases. (2) The ectopic pregnancy were 36 cases, and show echo-complex masses in 21 cases, and cul-de-sac fluid echo in 22 cases. (3) The cystic teratomas were 14 cases, and reveal mainly cystic or pure cystic masses in 10 cases, and calcification with posterior acoustic shadowing in 6 cases. (4) The uterine leiomyma were 11 cases, and reveal solid mass with abnormal uterine contour in 8 cases. (5) The malignant or borderline malignant lesions were 6 cases. (6) Of 153 cases, the pathologic diagnosis was possible in 98 cases (64.1%)

    Full Text Available Background: Old pelvis fractures are among the most challenging fractures to treat because of their complex anatomy, difficult-to-access surgical sites, and the relatively low incidence of such cases. Proper evaluation and surgical planning are necessary to achieve the pelvic ring symmetry and stable fixation of the fracture. The goal of this study was to assess the use of three-dimensional (3D printing techniques for surgical management of old pelvic fractures. Methods: First, 16 dried human cadaveric pelvises were used to confirm the anatomical accuracy of the 3D models printed based on radiographic data. Next, nine clinical cases between January 2009 and April 2013 were used to evaluate the surgical reconstruction based on the 3D printed models. The pelvic injuries were all type C, and the average time from injury to reconstruction was 11 weeks (range: 8-17 weeks. The workflow consisted of: (1 Printing patient-specific bone models based on preoperative computed tomography (CT scans, (2 virtual fracture reduction using the printed 3D anatomic template, (3 virtual fracture fixation using Kirschner wires, and (4 preoperatively measuring the osteotomy and implant position relative to landmarks using the virtually defined deformation. These models aided communication between surgical team members during the procedure. This technique was validated by comparing the preoperative planning to the intraoperative procedure. Results: The accuracy of the 3D printed models was within specification. Production of a model from standard CT DICOM data took 7 hours (range: 6-9 hours. Preoperative planning using the 3D printed models was feasible in all cases. Good correlation was found between the preoperative planning and postoperative follow-up X-ray in all nine cases. The patients were followed for 3-29 months (median: 5 months. The fracture healing time was 9-17 weeks (mean: 10 weeks. No delayed incision healing, wound infection, or nonunions occurred. The

  3. Prostate position relative to pelvic bony anatomy based on intraprostatic gold markers and electronic portal imaging

    International Nuclear Information System (INIS)

    Purpose: To describe the relative positions and motions of the prostate, pelvic bony anatomy, and intraprostatic gold fiducial markers during daily electronic portal localization of the prostate. Methods and Materials: Twenty prostate cancer patients were treated supine with definitive external radiotherapy according to an on-line target localization protocol using three or four intraprostatic gold fiducial markers and an electronic portal imaging device. Daily pretherapy and through-treatment electronic portal images (EPIs) were obtained for each of four treatment fields. The patients' pelvic bony anatomy, intraprostatic gold markers, and a best visual match to the target (i.e., prostate) were identified on simulation digitally reconstructed radiographs and during daily treatment setup and delivery. These data provided quantitative inter- and intrafractional analysis of prostate motion, its position relative to the bony anatomy, and the individual intraprostatic fiducial markers. Treatment planning margins, with and without on-line localization, were subsequently compared. Results: A total of 22,266 data points were obtained from daily pretherapy and through-treatment EPIs. The pretherapy three-dimensional (3D) average displacement of the fiducial markers, as a surrogate for the prostate, was 5.6 mm, which improved to 2.8 mm after use of the localization protocol. The bony anatomy 3D average displacement was 4.4 mm both before and after localization to the prostate (p = 0.46). Along the superior-inferior (SI), anterior-posterior (AP), and right-left (RL) axes, the average prostate displacement improved from 2.5, 3.7, and 1.9 mm, respectively, before localization to 1.4, 1.6, and 1.1 mm after (all p < 0.001). The pretherapy to through-treatment position of the bony landmarks worsened from 1.7 to 2.5 mm (p < 0.001) in the SI axis, remained statistically unchanged at 2.8 mm (p = 0.39) in the AP axis, and improved from 2.0 to 1.2 mm in the RL axis (p < 0.001).

    The evolution of the multidisciplinary approach to the management of chronic conditions is a reflection of how medicine has evolved from a singular to a plural effort recognising the complex causations and consequences of such disorders. This thinking should not be confined to tertiary centres alone and should be adapted where local expertise is available. Such an approach is especially important in pelvic floor disorders, where the correlation between structure and function is not always straightforward. There is a need to avoid over-investigation by accurate clinical assessment allied to tailored investigation, leading to a step-wise approach to treatment (which may include behavioural, physiotherapy, medical or surgical management). The algorithms here on faecal incontinence, obstetric trauma, pelvic floor prolapse and chronic pelvic pain attempt to provide such a logical approach to patients.

  5. Development and evolution of the muscles of the pelvic fin.

    Full Text Available Locomotor strategies in terrestrial tetrapods have evolved from the utilisation of sinusoidal contractions of axial musculature, evident in ancestral fish species, to the reliance on powerful and complex limb muscles to provide propulsive force. Within tetrapods, a hindlimb-dominant locomotor strategy predominates, and its evolution is considered critical for the evident success of the tetrapod transition onto land. Here, we determine the developmental mechanisms of pelvic fin muscle formation in living fish species at critical points within the vertebrate phylogeny and reveal a stepwise modification from a primitive to a more derived mode of pelvic fin muscle formation. A distinct process generates pelvic fin muscle in bony fishes that incorporates both primitive and derived characteristics of vertebrate appendicular muscle formation. We propose that the adoption of the fully derived mode of hindlimb muscle formation from this bimodal character state is an evolutionary innovation that was critical to the success of the tetrapod transition.

    Endometriosis is characterized by the presence of normal endometrial tissue outside the uterine cavity. In patients with deep pelvic endometriosis, uterosacral ligaments, rectum, rectovaginal septum, vagina or bladder may be involved. Clinical manifestations may be variable, including pelvic pain, dysmenorrhea, dyspareunia, urinary symptoms and infertility. Complete surgical excision is the gold standard for treating this disease, and hence the importance of the preoperative work-up that usually is limited to an evaluation of sonographic and clinical data. Magnetic resonance imaging is of paramount importance in the diagnosis of endometriosis, considering its high accuracy in the identification of lesions intermingled with adhesions, and in the determination of peritoneal lesions extent. The present pictorial review describes the main magnetic resonance imaging findings in deep pelvic endometriosis. (author)

    Full Text Available Background: Pelvic lymph node metastasis (LNM is an important prognostic factor in cervical cancer. Cervical squamous cell carcinoma accounts for approximately 75-80% of all cervical cancers. Analyses of the effects of the number of positive lymph nodes (LNs, unilateral versus bilateral pelvic LNM and a single group versus multiple groups of pelvic LNM on survival and recurrence of cervical squamous cell carcinoma are still lacking. The study aimed to analyze the effects of the number of positive pelvic LNs and a single group versus multiple groups of pelvic LNM on survival and recurrence. Methods: We performed a retrospective review of 296 patients diagnosed with Stage IA-IIB cervical squamous cell carcinoma who received extensive/sub-extensive hysterectomy with pelvic lymphadenectomy/pelvic LN sampling at Peking University People′s Hospital from November 2004 to July 2013. Ten clinicopathological variables were evaluated as risk factors for pelvic LNM: Age at diagnosis, gravidity, clinical stage, histological grade, tumor diameter, lymph-vascular space involvement (LVSI, depth of cervical stromal invasion, uterine invasion, parametrial invasion, and neoadjuvant chemotherapy. Results: The incidence of pelvic LNM was 20.27% (60/296 cases. Pelvic LNM (P = 0.00 was significantly correlated with recurrence. Pelvic LNM (P = 0.00, the number of positive pelvic LNs (P = 0.04 and a single group versus multiple groups of pelvic LNM (P = 0.03 had a significant influence on survival. Multivariate analysis revealed that LVSI (P = 0.00, depth of cervical stromal invasion (P = 0.00 and parametrial invasion (P = 0.03 were independently associated with pelvic LNM. Conclusions: Patients with pelvic LNM had a higher recurrence rate and poor survival outcomes. Furthermore, more than 2 positive pelvic LNs and multiple groups of pelvic LNM appeared to identify patients with worse survival outcomes in node-positive IA-IIB cervical squamous cell carcinoma.

    The incidence of pelvic fractures is relatively low compared with other fracture locations. The low incidence is in great contrast to the high morbidity and mortality. Particularly in the elderly, with apparently isolated fractures of the pubic rami, these observations are believed to be due to additional occult lesions of the posterior pelvic ring. In these cases diagnosis cannot be established by conventional imaging alone and SPECT/CT is considered as a diagnostic adjunct. The aim of this study was to assess concomitant bony or soft tissue lesions within the pelvic ring in a population of patients with fractures of the anterior elements. In all patients with no obvious lesions of the posterior pelvic ring on X-rays and CT or with suspicious but inconclusive findings on CT an additional SPECT/CT was carried out in a non-acute setting within 3 days of the trauma. In all cases additional lesions within the pelvic ring were found. Most lesions were vertical sacral fractures, followed by transverse fractures, one non-dislocated fracture of the acetabulum on the side of the pubic rami fracture, and one post-traumatic dilatation of the sacroiliac joint with increased tracer uptake. According to our results after SPECT/CT all patients with pubic rami fracture suffered additional lesions, none detectable previously by X-ray or CT, within the pelvic ring. In this context SPECT/CT has proved to be very helpful in the clinical routine to visualize occult fractures and instability within the sacroiliac joint. (orig.)

    Aim: To evaluate the effect of hyoscine butylbromide (HBB) on image quality and lesion and organ visualization in pelvic magnetic resonance imaging (MRI) Materials and methods: A prospective, ethically approved study was undertaken of 47 patients attending for pelvic MRI at a cancer centre. T2-weighted transverse and sagittal sequences were performed before and after intravenous injection of 20 mg HBB. Three radiologists independently scored anonymized image series for overall image quality, visualization of pelvic lesions and visualization of individual pelvic organs. Statistical analysis was performed to assess improvements in radiologists' scores post-HBB administration. Radiologists also assessed pre-HBB administration T1-weighted images for degree of bowel peristalsis to determine whether this could predict improvement in post-HBB T2-weighted image scores. Side effects of HBB were recorded using a patient questionnaire. Results: Radiologists' scores for image quality and lesion visualization were significantly higher on the post-HBB administration T2-weighted series (p < 0.0005). Scores for the visualization of the bladder, rectum, pelvic bowel, prostate, and seminal vesicles (all p < 0.0005), cervix (p = 0.019) and vagina (p = 0.0001) were also significantly higher post-HBB administration. Scores for the degree of peristalsis on T1-weighted images were not related to improvement in image quality or lesion visualization on T2-weighted images post-HBB administration. Side effects of HBB were mild and self-limiting. Conclusion: Intravenous HBB administration improves image quality and lesion visualization in oncological pelvic MRI and is recommended for routine use.

    Research has suggested that athletes involved in high-intensity sports for sustained periods have a higher probability of experiencing prolonged second stage of labour compared to non-athletes. The mechanism responsible for this complication is unknown but may depend on the relative size or tone of the pelvic floor muscles. Prolonged training can result in enlargement and stiffening of these muscles, providing increased resistance as the fetal head descends through the birth canal during a vaginal birth. On the other hand, recent studies have suggested an association between increased muscle bulk in athletes and higher distensibility. This project aims to use mathematical modelling to study the relationship between the size and tone of the pelvic floor muscles and the level of difficulty during childbirth. We obtained sets of magnetic resonance (MR) images of the pelvic floor region for a female athlete and a female non-athlete. Thirteen components of the pelvic floor were segmented and used to generate finite element (FE) models. The fetal head data was obtained by laser scanning a skull replica and a FE model was fitted to these data. We used contact mechanics to simulate the motion of the fetal head moving through the pelvic floor, constructed from the non-athlete data. A maximum stretch ratio of 3.2 was induced in the muscle at the left lateral attachment point to the pubis. We plan to further improve our modelling framework to include active muscle contraction and fetal head rotations in order to address the hypotheses that there is a correlation between the level of difficulty and the size or tone of the pelvic floor muscles.

    Full Text Available Spinal cord injury without radiological abnormality is rare in adults. Below we present a case report of 20 yrs old male with isolated cervical cord injury, without accompanying vertebral dislocation or fracture involving the spinal canal rim. He fell down on plain and smooth ground while carrying 40 kg weight overhead and developed quadriparesis with difficulty in respiration. Plain radiographs of the neck revealed no fractures or dislocations. MRI showed bulky spinal cord and an abnormal hyper intense signal on the T2W image from C2 vertebral body level to C3/4 intervertebral disc level predominantly in the anterior aspect of the cord The patient was managed conservatively with head halter traction and invasive ventilatory support for the initial 7 days period in the ICU. In our patient recovery was good and most of the neurological deficit improved over 4 weeks with conservative management.

    The purpose of this study was to investigate the radiographic images of Temporomandibular joint trouble patients. This study included 186 patients with the chief complaints of TMJ pain and dysfunction. Their age ranged from 17 to 68 years. All patients were identified in the department of Dental Radiology at the Infirmary of College of Dentistry, Seoul National University, during the period from Apr. 1978 to Jun. 1979. The author has observed the radiographic variations of two positions of condylar head taken by modified transcranial oblique-lateral projection, which are one in centric occlusion and the other in 1 inch(2.54 cm) mouth open. The results were obtained as follows; 1. In centric occlusion, the distances and positional relationship between the summit of condylar head and the deepest point of articular fossa revealed more or less large variations; Normal range is of 37.9%, anterior displacement of 37.3% and posterior displacement of 22.6%. 2. In the horizontal movement of condylar heads when on 1 inch mouth open, it was revealed that normal range was of 46.5%, anterior displacement of 12.3%, posterior displacement of 41.1%. 3. In the positional interrelationship of both condylar heads when on 1 inch mouth open, it was revealed that symmetry(71.5%) occurred approximately 2.5 times as many as asymmetry. 4. In both centric and 1 inch mouth open, it was showed that almost all estimated figures were greater in male than in female, and in the horizontal movement of condylar head when on 1 inch open, it was showed that hypermobility was dominant in male and hypomobility in female.

(i) Respondents considered increased professional standing of radiographers, best use of manpower resources, reduced pressure on the service and improved recruitment and retention, as positive advantages of radiographer development. (ii) The potential impact on radiology specialist registrar training, lack of clear medico-legal responsibilities and radiographers recognising the limitations of their abilities were identified as the main areas of radiologist anxiety. (iii) Fifty-seven percent did not consider current post-registration radiography education and training resources adequate to underpin the requirement of developed roles. (iv) Barriers to radiographer development were identified as lack of radiography and radiology staff, suitable education, financial constraints, traditional views and resistance to change. (v) Eighty-two percent reported support for radiographer role development and willingness to participate actively in developments. Conclusion: Despite reservations Scottish radiologists are supportive of the development of radiography colleagues, however, guidance is required on the medico-legal and accountability aspects of radiographers assuming new roles. Radiologist involvement in education and training for new roles may increase their confidence and trust in radiographers to work within the limitations of their competency and training.

    Full Text Available Since bovine teeth have been used as substitutes for human teeth in in vitro dental studies, the aim of this study was to compare the radiographic density of bovine teeth with that of human teeth to evaluate their usability for radiographic studies. Thirty bovine and twenty human teeth were cut transversally in 1 millimeter-thick slices. The slices were X-rayed using a digital radiographic system and an intraoral X-ray machine at 65 kVp and 7 mA. The exposure time (0.08 s and the target-sensor distance (40 cm were standardized for all the radiographs. The radiographic densities of the enamel, coronal dentin and radicular dentin of each slice were obtained separately using the "histogram" tool of Adobe Photoshop 7.0 software. The mean radiographic densities of the enamel, coronal dentin and radicular dentin were calculated by the arithmetic mean of the slices of each tooth. One-way ANOVA demonstrated statistically significant differences for the densities of bovine and human enamel (p 0.05. Based on the results, the authors concluded that: a the radiographic density of bovine enamel is significantly higher than that of human enamel; b the radiodensity of bovine coronal dentin is statistically lower than the radiodensity of human coronal dentin; bovine radicular dentin is also less radiodense than human radicular dentin, although this difference was not statistically significant; c bovine teeth should be used with care in radiographic in vitro studies.

    Full Text Available Background Identification of common technical errors during preparation of panoramic radiographs, how affect the quality and interpretation of the radiographs and the techniques used to deal with such errors, might help prevent unnecessary radiation to patients and save their time and money. Objectives The current study aimed to identify common errors in the panoramic radiographs taken by post-graduate students in the Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Hamadan University of Medical Sciences. Patients and Methods A total of 220 conventional and digital panoramic radiographs of patients who were referred to the Department of Radiology were selected for the current study. All the radiographs had been taken by the post-graduate radiology students. The radiographs were evaluated by two oral and maxillofacial radiologists, under standard visualization conditions, to identify technical errors. Results From the evaluated radiographs, 193 (87.7% had one or more technical errors. The most common error was twisting of the head to one side (31.8%, followed by superimposition of the palatoglossus air space on the apices of maxillary incisors (30.9%. Conclusions The errors identified in the present study might be attributed to a lack of proper verbal communication between the patients and the post-graduate students, which necessitates continuous education of operators who take panoramic radiographs.

  6. An exploratory study of radiographer's perceptions of radiographer commenting on musculo-skeletal trauma images in rural community based hospitals

    International Nuclear Information System (INIS)

    Aim: This study sought to explore the perceptions of community hospital based radiographers in North East Scotland regarding the practice of radiographer commenting on musculo-skeletal trauma images. Method: A purposive sample of radiographers (n = 8) were recruited from community hospitals throughout the North-east of Scotland. A qualitative, exploratory study was conducted employing semi-structured interviews consisting of one focus group and two individual interviews. The interviews were audio recorded and transcribed in full to allow thematic analysis of the data using a framework adapted from Pope and Mays (2006). Main findings: This study revealed that the practice of radiographer commenting in the community provides a valuable front line opinion on musculo-skeletal trauma image appearances to enhance diagnostic outcomes for patients and streamline their care pathway. The appreciation shown from inter-professional colleagues for this practice induced feelings of professional pride and job satisfaction in the sample group. All participants expressed a desire to undertake additional training to allow progression from radiographer commenting to radiographer reporting of musculo-skeletal trauma images. Perceived barriers to the practice of radiographer commenting were time constraints and a lack of support with regards to continuing professional development (CPD) opportunities and mentorship from radiology colleagues. Conclusion: The practice of radiographer commenting in the community setting should be supported by ongoing training, and radiologist involvement in mentoring could provide radiographers with a valuable support mechanism. The voice of all radiographers regarding this extended role must be heard by professional leaders to ensure that the skills and education required for radiographer commenting are provided and subsequent patient care is not compromised

    Full Text Available We report a case of a 50-year-old woman who presented to the emergency department with large bowel obstruction and anemia. The initial imaging study suggested an inoperable rectal tumor with involvement of surrounding structures. In this paper, we discuss the diagnostic work-up of this patient with a diagnosis of pelvic/perirectal inflammatory myofibroblastic tumor (IMT. IMT is a rare tumor with intermediate malignant potential that frequently mimics clinical and imaging features of malignancy. Additionally, to the best of our knowledge, this is the first case of a pelvic IMT that regressed without surgical excision.

    Management of large calculi in ectopic pelvic kidneys poses a challenge to the urologist. Risk of injury to surrounding abdominal viscera and vasculature makes open surgery as well as percutaneous nephrostolithotomy in an ectopic kidney a challenging procedure. Laparoscopic management avoids open surgery and associated morbidity and offers added safety. We report the management of symptomatic stones in a pelvic ectopic kidney lying anterior to the L5 vertebra and sacrum by transmesocolic laparoscopic pyelolithotomy in an 11-year-old child. Complete stone clearance was achieved with no complications and an uneventful postoperative recovery. The patient was discharged 72 hours after the surgery. PMID:17761093

    Epidermoid cyst is a frequent benign cutaneous tumor. The pelvic localization does not occur very often. The literature that taps into such cases is very limited in scope. Here is a report of a 27-year-old woman with a giant pelvic retroperitoneal epidermoid cyst. The use of ultrasound exploration and computed tomography has indicated ovarian origins. The surgery also revealed a retroperitoneal epidermoid cyst, uterus and ovaries were all intact. The evacuation of a cyst was found to contain lamellas of keratin. Histology permitted us to confirm the diagnosis. The patient was faring well after two years of followup. PMID:23150734

    The authors inspected 112 patients with diagnostic urogynecologic and urodynamic criteria. They suffered from urinary stress incontinence. Forty patients effected rehabilitative therapy of the pelvic floor with visits twice weekly with a method which included: pelvic muscle exercises, biofeedback and functional electrostimulation. The patients were divided into two groups in accordance with the kind of urinary stress incontinence: in the first group there were patients with genuine urinary stress incontinence, in the second group patients with mixed urinary stress incontinence. The results at the end of treatment reported a proportion of success of 66% in the first group and of 54% in the second group.

  13. A prospective study of urinary tract infection during pelvic radiotherapy

    International Nuclear Information System (INIS)

    The frequency of urinary tract infection before and during pelvic radiotherapy was studied prospectively in 172 patients who were not catherised and had not had instrumentation for at least 4 weeks prior to radiotherapy. The incidence of urinary tract infection prior to radiotherapy was 17% and a further 17% of patients develped a urinary tract infection during radiotherapy. Mid-stream specimens of urine (MSU) should be examined for infection on a weekly basis during pelvic radiotherapy not only to identify this additional 17% of patients but also to detect those patients who have persistent urinary tract infection in spite of treatment with appropriate antibiotics.

  15. Radiographic heart-volume estimation in normal cats

    International Nuclear Information System (INIS)

    Heart volume mensuration was evaluated on conventional radiographs from eight normal cats in different body positions using computed tomography (CT). Heart volumes were calculated from orthogonal thoracic radiographs in ventral and dorsal recumbency and from radiographs exposed with a vertical X-ray beam in dorsal and lateral recumbency using the formula for an ellipsoid body. Heart volumes were also estimated with CT in ventral, dorsal, right lateral and left lateral recumbency. No differences between heart volumes from CT in ventral recumbency and those from CT in right and left lateral recumbency were seen. In dorsal recumbency, however, significantly lower heart volumes were obtained. Heart volumes from CT in ventral recumbency were similar to those from radiographs in ventral and dorsal recumbency and dorsal/left lateral recumbency. Close correlation was also demonstrated between heart volumes from radiographs in dorsal/ left lateral recumbency and body weights of the eight cats

  16. Inferring Morphology and Strength of Magnetic Fields From Proton Radiographs

    2016-01-01

    Proton radiography is an important diagnostic method for laser plasma experiments, and is particularly important in the analysis of magnetized plasmas. The theory of radiographic image analysis has heretofore only permitted somewhat limited analysis of the radiographs of such plasmas. We furnish here a theory that remedies this deficiency. We show that to linear order in magnetic field gradients, proton radiographs are projection images of the MHD current along the proton trajectories. We demonstrate that in the linear approximation, the full structure of the perpedicular magnetic field can be reconstructed by solving a steady-state inhomogeneous 2-dimensional diffusion equation sourced by the radiograph fluence contrast data. We explore limitations of the inversion method due to Poisson noise, to discretization errors, to radiograph edge effects, and to obstruction by laser target structures. We also provide a separate analysis that is well-suited to the inference of isotropic-homogeneous magnetic turbulence...

  20. Prospective study of nutritional support during pelvic irradiation

    International Nuclear Information System (INIS)

    A prospective study of nutritional support during pelvic irradiation was carried out in 32 patients with a primary pelvic malignancy and prior weight loss. Both curative and palliative patients were eligible for the study. Seventeen patients were randomized to receive intravenous hyperalimentation (IVH) and fifteen patients served as controls who were maintained on their regular diet. Patients were stratified by percent body weight loss. Tolerance to therapy was assessed by evaluation of functional status and by using nutritional parameters of body weight change, change in serum protein levels, and response to delayed hypersensitivity skin tests. The curative IVH group tolerated therapy well by both functional and nutritional measurements. All curative IVH patients completed the planned radiation therapy without a treatment break and were fully active following treatment. Patients gained an average of 4.0 kg body weight during irradiation, which was significantly different from the curative control patients. They demonstrated a significant increase in serum transferrin reflecting an improvement in visceral protein. In addition, all showed a positive response to delayed hypersensitivity skin tests at the completion of irradiation. The palliative IVH patients often did poorly because of progression of disease and demonstrated only an elevation of serum transferrin during treatment. The results in the curative IVH group suggest a potential adjunctive role for intravenous hyperalimentation in the malnourished cancer patient undergoing pelvic irradiation. Clearly, further study of nutritional support during pelvic irradiation is needed using curative patients with a single tumor type and significant prior weight loss
