Full Text Available Fracture of mandible is relatively less common in pediatric population when compared to adults. Management of pediatric mandibular fracture is a very complex issue and requires accurate and early treatment. Although the general principles of treatment remain the same as adult but various factors which influence the choice of management: age, dentition status, site involved, amount of displacement, number of fractures, and socioeconomic status. This case report describes a conservative way of management of moderately displaced mandibular fracture with the help of closed reduction achieved using intermaxillary fixation (IMF with help of elastics using orthodontic brackets. A 9-year-old male child was treated for body of mandible fracture using this technique. The IMF was removed after 3 weeks and adequate bone union was demonstrated clinically and radiographically.

To evaluate the effectiveness of the screw-based intermaxillary traction combined with occlusal splint in the treatment of pediatric mandibular condylar fracture. Between June 2005 and December 2013, 35 pediatric patients with 49 mandibular condylar fractures were treated, and the clinical data were retrospectively reviewed. There were 25 boys and 10 girls, aged 3-13 years (mean, 7.3 years). The injury causes included falling (18 cases), traffic accident (14 cases), and violence (3 cases). The time between injury and treatment was 2-30 days (mean, 6.8 days). Restricted mouth opening was observed, and the maximal mouth opening was (22.74 +/- 7.22) mm except 3 patients who were too young to measure. Condylar fractures were located at the left (12 cases), at the right (9 cases), at bilateral (14 cases) based on the sites; and fractures were classified as intracapsular (35 fractures), neck (10 fractures), and subcondylar (4 fractures) based on the fracture line. Four self-drilling titanium screws were inserted into the alveolar bone of both maxilla and mandible. After screw inserting, an occlusal splint with a fulcrum was used on the affected side and elastic band was put to perform anterior intermaxillary traction. After 1 month, the screws and splint were removed. Follow-up examinations were carried out on schedule. All the patients were followed up from 6 months to 8 years and 10 months (median, 71 months). No screw-related complication occurred in the others except one case of screw loosening. The postoperative maximal mouth opening was (38.82 +/- 2.02) nim. Mild joint noise was found in 4 cases and opening deviation occurred in 6 cases. Radiographic results demonstrated complete condyle remodeling was achieved in 24 cases (32 fractures), and moderate remodeling in 11 cases (17 fractures) at last follow-up. The screw-based intermaxillary traction combined with occlusal splint might be an effective method for pediatric mandibular condylar fracture. The screw-related

Studies have reported that thoracic CT may provide greater sensitivity compared with radiography in detection of pediatric rib fractures and fracture healing. The additional sensitivity afforded by thoracic CT may have medicolegal implications where abuse is suspected. To determine the additional value of postmortem thoracic CT compared with radiography in detecting pediatric rib fractures, and fracture healing, using autopsy findings as a gold standard. We retrospectively reviewed 56 coroner's cases with postmortem radiography and CT thoracic survey. All studies underwent primary interpretation by one or two radiologists. The study radiologist independently reviewed all images from 13 patients with positive findings on radiography, CT or autopsy. Sensitivity and specificity between observers and imaging modalities were compared. Primary interpretation: Fractures were recognized on radiography in 5/12 patients who had fractures found at autopsy, and on CT in 8/12 patients. In total, 29% (24/83) of fractures were reported on radiography, and 51% (52/101) of fractures were reported on CT. Study radiologist: Fractures were recognized on radiography in 7/12 patients who had fractures found at autopsy, and on CT in 11/12 patients. In total, 46% (38/83) of fractures were reported on radiography, and 85% (86/101) of fractures were reported on CT. Postmortem thoracic CT provides greater sensitivity than radiography in detecting pediatric rib fractures, most notably in anterior and posterior fractures. However, the degree of improvement in sensitivity provided by CT might depend on observer experience. (orig.)

Recent advances in external fixation technique and pin design have sought to minimize complications such as pin site infection and premature removal of the external fixator. Although newer forms of internal fixation have gained popularity, external fixation may still have a role in managing pediatric femoral shaft fractures. We sought to assess the time to healing, limb alignment, and complications observed in a cohort of pediatric patients with closed femoral shaft fractures who were treated with external fixation. Over a 15-year period, one surgeon treated 289 pediatric patients with femur fractures, 31 (11%) of whom received an external fixator. The general indications for use of an external fixator during the period in question included length-unstable fractures, metadiaphyseal location, refracture, and pathologic fracture. Six patients (19%) had inadequate followup data and four patients (13%) were treated with a combination of flexible intramedullary nails and external fixation, leaving 21 patients for analysis. Mean age at injury was 10 years (range, 6-15 years) and followup averaged 22 months (range, 5-45 months) after removal of the fixator. Radiographs were examined for alignment and limb length discrepancy. Complications were recorded from a chart review. Mean time in the fixator was 17 weeks (range, 9-24 weeks). One patient sustained a refracture and one patient with an isolated femur fracture had a leg length discrepancy > 2 cm. There were no pin site infections requiring intravenous antibiotics or additional surgery. One patient with Blount disease and previous tibial osteotomy developed transient peroneal nerve palsy. Despite improvements in pin design and predictable fracture healing, complications such as refracture and leg length discrepancy after external fixation of pediatric femoral shaft fractures can occur. However, external fixation remains a viable alternative for certain fractures such as length-unstable fractures, metadiaphyseal

Pediatric mandibular fractures are rare and their treatment remains controversial. Management is extremely complicated in mixed dentition as it is inherently dynamic and unstable. Treatment options include soft diet, intermaxillary fixation with eyelet wires, arch bars, circummandibular wiring, or stents. Alternative options include open reduction and internal fixation through either an intraoral or extraoral approach. This case report describes and evaluates the conservative technique of acrylic splint in the treatment of pediatric mandible fracture in a 12-year-old female child. The patient with isolated mandibular fracture was treated with acrylic splint and interdental wiring followed by evaluation of clinical and radiographic healing as well as the somatosensory status. Patient demonstrated clinical union to her pre-injury occlusion by three to four weeks. Panoramic finding supported the finding of clinical examination throughout the study. High osteogenic potential of the pediatric mandible allowed conservative management to be successful in this case.

Mandibular fractures are relatively less frequent in children when compared to adults. Pediatric patients present a unique challenge to maxillofacial surgeons in terms of their treatment planning and in their functional needs. We currently describe our experience with lateral compression open cap splint with circummandibular wiring as a treatment modality which involves fewer risks in treating pediatric symphysis/parasymphysis/body mandibular fractures. A retrospective analysis of pediatric patients with mandibular symphysis/parasymphysis/body fractures operated from January 2007 to January 2012 was performed. Clinical photographs and orthopantomogram assessment at the time of presentation, after treatment, and at 6 months postoperatively were evaluated. All the 10 patients were followed up until the period of 6 months, and none of them had any major complications. Postoperatively, there was satisfactory healing and union of fracture fragments in all the patients. Only one patient developed infection at submental region. The 6-month follow-up showed good occlusion, without interference in teeth eruption and no signs of temporomandibular joint problems. Lateral compression open cap splints for treatment of pediatric mandibular symphysis/parasymphysis/body fractures are reliable treatment modalities with regard to occlusion-guided fracture reduction.

The Genant semiquantitative (GSQ) method has been a standard procedure for diagnosis of vertebral fractures in adults but has only recently been shown to be of clinical utility in children. Observer agreement using the GSQ method in this age group has not been described. To evaluate observer agreement on vertebral readability and vertebral fracture diagnosis using the GSQ method in pediatric vertebral morphometry. Spine radiographs of 186 children with acute lymphoblastic leukemia were evaluated independently by three radiologists using the same GSQ methodology as in adults. A subset of 100 radiographs was evaluated on two occasions. An average of 4.7% of vertebrae were unreadable for the three radiologists. Intraobserver Cohen's kappa (κ) on readability ranged from 0.434 to 0.648 at the vertebral level and from 0.416 to 0.611 at the patient level, while interobserver κ for readability had a range of 0.330 to 0.504 at the vertebral level and 0.295 to 0.467 at the patient level. Intraobserver κ for the presence of vertebral fracture had a range of 0.529 to 0.726 at the vertebral level and was 0.528 to 0.767 at the patient level. Interobserver κ for fracture at the vertebral level ranged from 0.455 to 0.548 and from 0.433 to 0.486 at the patient level. Most κ values for both intra- and interobserver agreement in applying the GSQ method to pediatric spine radiographs were in the moderate to substantial range, comparable to the performance of the technique in adult studies. The GSQ method should be considered for use in pediatric research and clinical practice. (orig.)

Over the past decade, point-of-care ultrasound has become a common tool used for both procedures and diagnosis. Developing high-fidelity phantoms is critical for training in new and novel point-of-care ultrasound applications. Detecting skull fractures on ultrasound imaging in the younger-than-2-year-old patient is an emerging area of point-of-care ultrasound research. Identifying a skull fracture on ultrasound imaging in this age group requires knowledge of the appearance and location of sutures to distinguish them from fractures. There are currently no commercially available pediatric skull fracture models. We outline a novel approach to building a cost-effective, simple, high-fidelity pediatric skull fracture phantom to meet a unique training requirement. © 2015 by the American Institute of Ultrasound in Medicine.

Pediatric patients present a unique challenge to maxillofacial surgeons in terms of their treatment planning as well as in their functional and nutritional needs which are different from that of adult patients. Early literature has advocated conservative closed management of pediatric fractures to prevent complications. However recent advances in maxillofacial surgery has enabled us to use biodegradable plates and screws, which overcomes the limitations of metallic plates. We present a comparison of two cases of parasymphysis fracture treated with circum-mandibular wiring and biodegradable plate fixation their outcome in terms of fracture healing and functional stability.

Injuries around the foot and ankle are challenging. There is a paucity of literature, outside that of specialist orthopedic journals, that focuses on this subject in the pediatric population. In this review, we outline pediatric foot and ankle fractures in an anatomically oriented manner from the current literature. Our aim is to aid the emergency department doctor to manage these challenging injuries more effectively in the acute setting. These injuries require a detailed history and examination to aid the diagnosis. Often, plain radiographs are sufficient, but more complex injuries require the use of magnetic resonance imaging. Treatment is dependent on the proximity to skeletal maturity and the degree of displacement of fracture. Children have a marked ability to remodel after fractures and therefore mainstay treatment is immobilization by a cast or splint. Operative fixation, although uncommon in this population, may be necessary with adolescents, certain unstable injuries or in cases with displaced articular surface. In the setting of severe foot trauma, skin compromise and compartment syndrome of the foot must be excluded. The integrity of the physis, articular surface and soft tissues are all equally important in treating these injuries.

We assessed the clinical results of a biodegradable plate system for the internal fixation of mandibular fractures in children, and observed the imaging features of fracture healing and bone changes around the biodegradable plates and screws during follow-up. We enrolled 39 patients (22 male, 17 female, average age 4 years 10 months) with different mandibular fractures. We used 2.0-mm resorbable plates to repair the fractures. Postoperative follow-up ranged from 6 months to 5 years; average follow-up was 1 year 2 months. The outcome measures identified and assessed included facial symmetry, mouth opening, occlusal relationship, infection, nonunion, malunion, and plate dehiscence. We fixed 42 fractures with 43 resorbable plates; the fracture site of one patient (aged 11 years 3 months) was fixed with two plates. Two patients developed small fistulas at the intraoral incision 2 months after surgery; the fistulas healed after 1 month without special treatment. In the other patients, the incision healed well, there was facial symmetry, mouth opening was >35 mm, and occlusion was good. Follow-up computed tomography examination data were available for 20 cases, and revealed different degrees of radiolucency indicating that osteolysis had occurred. Radiolucency was observed around the resorbable plates 1 month after the surgery. The extent and depth of the radiolucent region were obvious within 1 year of surgery. In the second year, there were obvious repairs, with the bony defect areas becoming shallower. After 2 years, the bony defect areas had almost disappeared. Biodegradable fixation devices are safe and efficient for treating pediatric mandibular fractures. Osteolysis commonly follows biodegradable fixation of pediatric mandibular fractures, and has no adverse effect on fracture healing.

To compare the effectiveness of open reduction and conservative treatment for pediatric mandibular condylar fractures and to provide the evidence for the selection of clinical therapy. The clinical data were retrospectively analyzed from 25 patients with the mandibular condylar fractures between January 1988 and December 2006. Of them, 8 patients (11 fractures) were treated with surgical treatment (surgical group) and 17 patients (22 fractures) with non-surgical treatment (non-surgical group). In surgical group, there were 6 males (9 fractures) and 2 females (2 fractures) with an age range of 8-13 years; fracture was caused by tumbling in 7 cases and by traffic accident in 1 with an interval of 1-6 days between injury and hospitalization; and 5 cases were identified as unilateral condylar fractures (3 complicated by mental fractures) and 3 cases as bilateral condylar fractures complicated by mental fractures. In non-surgical group, there were 12 males (15 fractures) and 5 females (7 fractures) with an age range of 3-12 years; fracture was caused by falling from height in 4 cases, by tumbling in 10, and by traffic accident in 3 with an interval of 1-25 days between injury and hospitalization; and 12 cases were identified as unilateral condylar fractures (3 complicated by mental fractures) and 5 cases as bilateral condylar fractures (1 complicated by mental fracture). Incision healed by first intention in surgical group, and 25 cases were followed up 1-6 years with an average of 3.5 years. At 12 months after treatment, no temporomandibular joint pain, eating disorder, or limited mandibular movement occurred in 2 groups. No significant difference was observed in opening mouth extent, protrusive and lateral movements between 2 groups at 6 and 12 months (P > 0.05). During centric occlusion, mental point located at the midline with symmetric face figure. Two patients in surgical group and 3 in non-surgical group had slight snap when opening their mouths.

The proper management of complex pediatric mandibular fractures remains a topic of debate because of the relatively uncommon presentation of these fractures, combined with concerns related with deciduous teeth, tooth buds, and growth inhibition. In this current study, we present a novel approach to the repair of bilateral condylar fractures with concomitant symphyseal fracture in a 4-year-old girl. Manual closed reduction was first obtained, followed by placement of a transfacial Steinman pin through the angles of the mandible and placement of circummandibular wires. Maxillomandibular fixation remained for 2 weeks and the Steinman pin was removed after 11 weeks. At 3 months of postsurgical follow-up, the patient displayed class I occlusion, facial symmetry, full range of jaw motion, and absence of deviation or pain on full oral excursion. Radiographic findings also revealed complete resolution of the symphyseal fracture with appropriate condylar healing and alignment.

The use of the vacuum-assisted closure device (VAC; KCI, San Antonio, Texas) has given the orthopedist a new tool for the successful management of severe traumatic wounds and open fractures. While the VAC's role in the adult population is proving itself as an improved therapy compared to "traditional wound care," it's role within pediatric orthopedics remains less well defined. Questions remain whether VAC therapy provides benefit regarding decreased infection rates as well as decreased need for extensive soft tissue coverage procedures. A review was therefore performed of a pediatric level I trauma center's experience using the VAC therapy for pediatric open fractures with a focus on the rate of superficial, deep, and chronic infection. A retrospective chart review spanning 4.5 years of all pediatric patients younger than 18 years with an open fracture initially treated with VAC therapy was conducted at a level I pediatric trauma center. This yielded 28 patients with 37 open fractures aged 2 to 17 years who were initially treated with wound VAC therapy. Subsequent chart review of these patients was performed examining in-hospital records, operative notes, and clinical follow-up visits for documented cases of superficial, deep, or chronic infection. Of 37 open pediatric fractures treated with a wound VAC, there were no cases of superficial infection and 2 cases of deep infection for an overall infection rate of 5%. Both infections resolved with surgical intervention and antibiotics without chronic infection development. When compared with historical controls, the use of VAC therapy for pediatric open fractures appears to be an equally safe and effective modality to help reduce infection in pediatric open fractures and should be considered a valuable tool in treating these injuries.

Maxillofacial fractures are encountered less commonly during childhood period due to anatomic, social, cultural, and environmental factors. Although the incidence of all maxillofacial fractures is 1% to 15% among pediatric and adolescent patients, this rate drops to less than 1% in children below 5 years age. Two hundred thirty-five cases (mandibular fracture were evaluated retrospectively. Patients records were examined in terms of age, gender, cause of fracture, fracture localization, number of fractures, fracture pattern, accompanying injuries, applied treatment methods, and complications. Mean age of cases was 9.2 years and 165 cases were male, 70 were female. Traffic accidents as the most common etiologic cause in all ages. Falls is the second most common cause which particularly affects children above age of 2 years. All cases had 333 fractures and the most common fracture localization was parasymphysis region (34%). The other most common fracture localizations were as follows: condyle (19%), corpus (13%), dentoalveolar region (12%), angulus (11%), symphysis region (9%), and ramus (2%). There was only a single fracture line in 145 cases, 40 cases had unilateral multiple and 50 cases had bilateral fracture lines. We applied symptomatic (conservative) treatment in 20 (8%) of our cases; fracture fixation with interdental wires or closed reduction methods were employed in 122 patients. Internal fixation with open reduction (OR) was performed on 51 (22%) patients. Both closed and OR techniques were carried out in 30 (13%) patients. Pediatric mandibular fractures, which are seen less frequently compared with those of adults, require a specific and different treatment. Although mostly less invasive methods are preferred, we believe that ORs should be considered when required.

Management of pediatric mandibular fractures presents a unique challenge to surgeons in terms of its numerous variations compared to adults. Both conservative and open methods have been advocated with their obvious limitations and complications. However, conservative modalities may not be possible in grossly displaced fractures, which necessitate the open method of fixation. We present a novel and simplified technique of transosseous fixation of displaced pediatric mandibular fractures with polyglactin resorbable suture, which provides adequate stability without any interference with tooth buds and which is easy to master.

The management of pediatric mandibular fractures is challenging for maxillofacial surgeons due to ongoing mandibular growth involving tooth buds. The treatment of such fractures has been a topic of much research. Generally accepted methods for the treatment of mandibular parasymphyseal or symphyseal fractures in children are conservative approaches involving the use of acrylic splints, lateral compression with an open-cap splint stabilized by circummandibular wiring, and maxillomandibular fixation with an arch bar and eyelet wiring. The aim of this technical note was to describe a straightforward approach to the treatment of pediatric mandibular fractures, in which an occlusal splint is secured to prevent trauma to the soft tissue, without the need for general anesthesia.

Over the last 20 years, a revolution in the management of facial fractures has taken place. Refinements in biocompatible materials of great delicacy and strength along with advances in our understanding of biomechanics of the face, have rendered complex injuries consistently amenable to accurate 3-dimensional reconstruction. Furthermore, with the availability of education in the techniques of internal rigid fixation, these advanced techniques have become routine practice in adults. However, the suitability of rigid internal fixation for children remains controversial. There are many concerns about the effect of implanted hardware in the mandible of a growing child. In addition, some evidence suggests that the elevation of functional matrix off of bone may result in alterations in development. The goal is to restore the underlying bony architecture to its pre-injury position in a stable fashion, with a minimal of aesthetic and functional impairment. However, in children the treatment of bony injuries is most easily accomplished by techniques that may adversely effect craniofacial development. While it is not entirely possible to resolve this dilemma, there exists an extensive body of experimental and clinical information on the appropriate management of pediatric mandibular fractures which can be used to formulate a rational treatment plan for most cases. This paper presents an overview of the contemporary understanding and application of these treatment principles.

Maxillofacial fractures are uncommon in the pediatric population, and their treatment is unique due to the psychological, physiological, developmental and anatomical characteristics of children. We present the case of a boy who was treated in an outpatient dental clinic using a lingual splint for the reduction, stabilization and fixation of a mandibular body fracture. This technique is a reliable, noninvasive procedure that dentists may consider in selected cases by referral to an oral and maxillofacial surgeon. It also limits the discomfort and morbidity that can be associated with maxillomandibular fixation or open reduction and internal fixation in pediatric patients.

The Mandible Injury Severity Score (MISS) has been used to evaluate adult mandibular fractures. The purpose of this study was to evaluate the MISS in a cohort of pediatric patients. This was a retrospective study of pediatric patients treated for mandibular fractures over a 20-year period. Patients were included if they had computed tomographic imaging available for review and had at least 1 post-treatment visit. The primary predictor variable was the MISS. Secondary predictors were demographic and injury-associated factors. The outcome was treatment-associated complications. Descriptive, bivariate, and multiple logistic regression statistics were computed. One hundred sixteen patients with mandibular fractures were identified; 73 (62.9%) met the inclusion criteria. The sample's mean age was 8.5 ± 4.1 years; 44% were girls. Motor vehicle collisions (60%) and falls (15.1%) were the most common mechanisms. More than 50% of patients had an extra-mandibular injury. The mean MISS was 13.5 ± 7.8. Forty-five percent of the sample underwent open reduction and internal fixation. Complications were noted in 20.5% of patients, of which malocclusion was the most common (8.2%). Increasing MISS was associated with complications (P pediatric patients with mandibular fractures, increased severity of injury is associated with complications, even after controlling for the effects of multiple confounders, including open treatment.

Stainless steel flexible Enders rods have been used for intramedullary fixation of pediatric femur fractures with good success. Despite intraoperative anatomic alignment, length unstable femur fractures can present postoperatively with fracture shortening. The purpose of this study was to review all length unstable pediatric femoral shaft fractures in which Enders rods were used and compare those that were locked to those that were not locked. A retrospective clinical and radiographic review of all patients at a single institution undergoing flexible intramedullary fixation for length unstable femoral shaft fractures from 2001 to 2008. A length unstable fracture was defined as either a comminuted fracture or a spiral fracture longer than twice the diameter of the femoral shaft. A total of 107 length unstable femoral shaft fractures fixed with Enders rods were identified, of which 37 cases (35%) had both Enders rods "locked" through the eyelet in the distal femur with a 2.7 mm fully threaded cortical screw. Patient demographics, clinical course, complications, fracture characteristics, and radiographic outcomes were compared for the locked and nonlocked groups. There were no statistical differences between the groups in demographic data, operative variables, fracture pattern, fracture location, time to union, femoral alignment, or major complications. Shortening of the femur and nail migration measured at 1 to 6 weeks postoperatively was significantly greater for the nonlocked cases. The medial and lateral locked Enders rods moved 1.3 and 1.9 mm, respectively, and the unlocked Enders each moved 12.1 mm (P < 0.05). At final follow-up there were significantly more (P < 0.05) clinical complaints in nonlocked group, including limp, clinical shortening, and painful palpable rods. Locking Enders rods for length unstable pediatric fractures is an excellent option to prevent shortening and resulted in no additional complications, added surgical time, or increased blood loss

Full Text Available Background/Aim. Femur fractures in children most often occur as a consequence of traffic accidents, during play and sport activities, and due to different pathological states. Diagnosis is rather simple and it includes physical and radiographycal examination. Femur fractures treatment in children can be operative and unoperative, depending on several facts: age, localisation and type of fracture, joint injuries of soft tissues, the presence of other injuries (in polytrauma, economical and social aspects, ect. The aim of this study was to present epidemiological characteristics of pediatric femur fractures, that is in the stage of development, including a special analysis of the used treatment techniques, as well as the comparison of the obtained data with those from the literature. Methods. The evaluation included following parameters: age, gender, cause, localisation and type of femur fracture, applied treatment and hospitalisation duration. Results. Among the presented 143 patients with femur fracture, 109 were boys and 34 were girls (3.2 : 1 ratio; p = 0.0001. Average age for both genders was 8.6 years, and no difference between boys and girls were found for the age (p = 0.758. In total, the most common fracture was diaphyseal fracture of femur in 93 (65.03% patients. The second was proximal fracture in 30 (20.98% patients, and the last distal fracture of the femur in 20 (13.99% patients (p = 0.0001. Three main causes of femur fracture can be distinguished: during play and sport activities in 67 (46.8% children, in traffic accidents in 64 (44.8% children, and pathological fractures in 12 (8.4% children. Inoperative treatment was applied in 82 (57.3% patients, and operative one in 61 (42.7% patients. The most common tretament was traction, in 71 (49.6% patients, followed by immobilization by hip spica cast mostly in young children. Intramedullar elastic nailing was applied in 16 (11.2% cases, and intramedullar rigid nailing (Küntscher in 19

In maxillofacial surgery, children represent a special group of patients, as they have significant differences from adults as far as the facial skeleton is concerned. The etiology and epidemiology of pediatric trauma involving the facial skeleton has been reported in a large series of patients. Nevertheless, few of these reports review large numbers of pediatric patients, and little is known about treatment protocols for fractures in children. The aims of this study were to retrospectively analyze the treatment methods and outcomes of pediatric mandibular fractures in children and young adolescents up to the age of 15 years, to discuss the findings, and to propose treatment protocols for maxillofacial fractures in childhood. The present study retrospectively analyzed the treatment methods and outcome of the pediatric mandibular fractures in children and young adolescents' up to the age of 15 years over a period of 5 years. All patients were followed up for an average period of 18 months, with a maximum follow-up of 2 years. A total of 74 patients were treated for mandibular and dentoalveolar fractures in children upto the age of 15 years at the Department of Oral and Maxillofacial Surgery at Nair Hospital Dental College, Mumbai from 2007 to 2012. AND CONCLUSIONS: The treatment methods used at our centre had satisfactory outcomes at the end of a follow-up period of 2 years. Reported complications were minimal. Our results confirm the usefulness of open reduction and plate fixation in older children (>12 years of age) and a conservative approach in younger children (≤12 years of age) in treating mandibular fractures.

Pediatric patients present a unique challenge to maxillofacial surgeons in terms of their treatment planning as well as in their functional and nutritional needs which are different from that of adult patients. Early literature has advocated conservative closed management of pediatric fractures to prevent complications. However recent advances in maxillofacial surgery has enabled us to use biodegradable plates and screws, which overcomes the limitations of metallic plates. We present a compar...

Management of mandibular condylar fractures is difficult in children with their inherently dynamic and unstable deciduous and mixed dentitions. We present a variation of the conservative fixed orthodontic approach that was used as an adjunct to aid in the reduction of a bilateral condylar fracture in a pediatric patient. A boy, aged 10 years 9 months, came with clinical signs and symptoms of mandibular fracture after being involved in a motor vehicle accident. A computed tomography scan showed a vertical fracture on the left condylar head, a displaced fracture of the right condylar neck, and a mandibular symphysis fracture. The patient was treated with an orthodontic fixed appliance instead of an arch bar splint, followed by elastic traction to achieve a proper occlusion and condylar remodeling. Follow-up appointments were made 2 weeks and 1, 2, 20, 37, and 49 months after treatment. Clinical recovery was observed 2 months after treatment. At the follow-up appointments at 20, 37, and 49 months, jaw function and occlusal relationship remained stable, and no ankylosis was observed. The computed tomography scans showed that the right condyle had remodeled, and the left condyle exhibited a slight curve in the head at 49 months posttreatment. The patient's satisfaction with these treatment results was high. Conservative treatment of a mandibular fracture by fixed orthodontic means is a viable treatment option that is relatively straightforward and cost-effective and has a high level of patient acceptance and comfort.

Full Text Available Pediatric mandibular fractures have been successfully managed in various ways. The use of a lingual splint is an option. This article presents a 4-year old boy who was treated by an alternative conservative method with a combination of an arch bar plus a lingual splint, circum-mandibular wiring and IMF for the reduction, stabilization and fixation of a severely displaced bilateral man‌dibular body fracture. This technique is a reliable, noninvasive procedure; it also limits the discomfort and morbidity associated with maxillomandibular fixation or open reduction and internal fixation in pediatric patients

Long-bone fractures represent one of the most commonly sustained injuries following trauma and account for nearly 4% of emergency department visits in the United States each year. These fractures are associated with a significant risk of bleeding and neurovascular compromise. Delays in their identification and treatment can lead to loss of limb and even death. Although emergency physicians currently rely predominantly on radiography for the examination of long-bone injuries, emergency ultrasound has several advantages over radiography and may be useful in the identification of long-bone fractures. Ultrasound is rapid, noninvasive, and cost-effective. Unlike radiography, ultrasound does not expose children to ionizing radiation, which has been linked to cancer. The goal of this study was to assess the agreement between emergency physicians' and radiologists' final assessments of suspected long-bone fractures using emergency ultrasound and radiography, respectively, in the pediatric population. This is a prospective study involving a convenience sample of pediatric patients (fracture. Suspected fractures were characterized by swelling, erythema, and localized pain. Patients who had a history of fracture, extremity deformity, orthopedic hardware in the traumatized area, or an open fracture were excluded from this study. Each investigator received limited, focused training in the use of ultrasonography for fracture identification and localization. This training consisted of a brief didactic session and video review of normal and fractured long-bones. A total of 53 subjects (mean age, 10.2 [SD, 3.8] years; 56.6% were male) were enrolled, which corresponded to 98 ultrasound examinations. Sixty-nine scans (70.4%) involved bones of the upper extremity, and 29 (29.6%) the lower extremity. Radiography identified a total of 43 fractures. The sensitivity and specificity of ultrasound in the detection of long-bone fractures were 95.3% (95% confidence interval [CI], 82

The objective of this study was to evaluate the use of one titanium microplate in the fixation of displaced pediatric parasymphysial mandibular fractures. The study was conducted on 7 children in the mixed dentition stage with displaced parasymphysial fracture. Patients' age ranged between 5 years 9 months and 8 years 4 months with an average of 7 years 1 month. Fractured bone segments were exposed, reduced and then fixed using 1.5 linear microplates at the inferior border of the mandible using monocortical screws, with 1.5 mm in diameter and 5 mm in length. Stainless steel wire was used as a tension band by ligating the teeth around the fracture line. Patients were followed up for occlusion and stability clinically and radiographically (panoramic X-ray and CT). According to clinical and radiographic post-operative follow-up, none of the patients showed displacement of the fixed bony segments. The present study concluded that using one microplate with 1.5 monocortical microscrews and dental tension band by a stainless steel wire could be adequate for fixing displaced pediatric parasymphysial mandibular fractures. This technique has the following advantages: decreases the amount of titanium used, decreases the risk of injury of the roots and teeth buds, and decreases the cost and time of surgery.

Pediatric supracondylar humerus fractures are common injuries that are often treated surgically with closed reduction and percutaneous pinning. Although surgical-site infections are rare, postoperative antibiotics are frequently administered without evidence or guidelines for their use. With the increasing prevalence of antibiotic-resistant organisms and heightened focus on health care costs, appropriate and evidence-based use of antibiotics is needed. We hypothesized that postoperative antibiotic administration would not decrease the rate of surgical-site infection. A billing query identified 951 patients with operatively treated supracondylar humerus fractures at our institution over a 15-year period. Records were reviewed for demographic data, perioperative antibiotic use, and the presence of surgical-site infection. Exclusion criteria were open fractures, open reduction, pathologic fractures, metabolic bone disease, the presence of other injuries that required operative treatment, and follow-up <2 weeks after pin removal. χ and Fisher exact test were used to compare antibiotic use to the incidence of surgical-site infection. Six hundred eighteen patients met our inclusion criteria. Two hundred thirty-eight patients (38.5%) received postoperative antibiotics. Eleven surgical-site infections were identified for an overall rate of 1.8%. The use of postoperative antibiotics was not associated with a lower rate of surgical-site infection (P=0.883). Patients with a type III fracture (P<0.001), diminished preoperative vascular (P=0.001) and neurological status (P=0.019), and postoperative hospital admission (P<0.001) were significantly more likely to receive postoperative antibiotics. Administration of postoperative antibiotics after closed reduction and percutaneous pinning of pediatric supracondylar humerus fractures does not decrease the rate of surgical-site infection.

Le Fort-type fractures are very rare in children, and there is a paucity of literature presenting their frequency and characteristics. The purpose of this study was to determine the etiology, frequency, and fracture patterns of children with severe facial trauma associated with pterygoid plate fractures in a pediatric cohort. We performed a retrospective cohort study of all children aged younger than 16 years with pterygoid plate and facial fractures who presented to our institute between 1990 and 2010. Patient charts and radiologic records were reviewed for demographic and fracture characteristics. Patients were categorized into 2 groups as per facial fracture pattern: non-Le Fort-type fractures (group A) and Le Fort-type fractures (group B). Other variables including dentition age, frontal sinus development, mechanism of injury, injury severity, and concomitant injuries were recorded. Univariate methods were used to compare groups. We identified 24 children; 25% were girls, and 20.8% were of nonwhite race. Most presented with Le Fort-type fracture patterns (group B, 66.7%). Age was significantly different between group A and group B (mean, 5.9 years and 9.9 years, respectively; P = .009). No significant differences in Injury Severity Score, rate of operative repair, and length of stay were found between groups. Most children with severe facial fractures and pterygoid plate fractures presented with Le Fort-type fracture patterns in our cohort. The mean age of children with Le Fort-type fractures was greater than in those with non-Le Fort-type patterns. However, Le Fort-type fractures did occur in younger children with deciduous and mixed dentition. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

The purpose of this study was to determine the efficacy and stability of the biodegradable fixation system for treatment of mandible fractures in pediatric patients by measuring the bite force. Sixty pediatric patients with mandibular fractures (36 males, 24 females) were included in this study. The 2.5-mm resorbable plates were adapted along Champy's line of ideal osteosynthesis and secured with four 2.5 mm diameter monocortical resorbable screws, 8 mm in length. All patients were followed for 10 months. Clinical parameters, such as soft tissue infection, nonunion, malunion, implant exposure, malocclusion, nerve injury, and bite force for stability, were prospectively assessed. Adequate fixation and primary bone healing was achieved in 100% of the cases. Six minor complications (10%) were observed: 2 soft tissue infections (3%), 1 plate dehiscence (2%), 1 malocclusion (2%), and 2 paresthesia (3%). 2.5-mm resorbable plating system along Champy's line of ideal osteosynthesis is a good treatment modality for mandible fractures in pediatric patients.

fractures by bioabsorbable elastic stable intramedullary nailing. Our clinical experience suggests that the procedure combined with long-arm casting is feasible in treating the pediatric forearm fractures. The technique may bring benefits to handling these challenging fractures. The disadvantages of metallic implants may be avoided. In addition, removal of the implant will not be required. There was one refracture in the series, but it was due to new high-energy trauma. According to our understanding, it was not related to the type of former osteosynthesis. However, ignoring the good preliminary experience, still we do not have results of the superiority of the procedure over traditional elastic stable intramedullary nailing. Our ongoing randomized multicenter study is aimed to determine its long-term outcome against the present golden standard. Nevertheless, due to encouraging preliminary results, we see it necessary to report the technique.

The use of rigid fixation in children is controversial and may cause growth retardation along cranial suture lines. Intermaxillary fixation for mandibular fractures should be used cautiously as bony ankylosis in the temporomandibular joint (TMJ) and trismus may develop. The high osteogenic potential of the pediatric mandible allows non-surgical management to be successful in younger patients with conservative approaches. In this case, successful conservative treatment of mandibular fracture of a 3-year-old patient is presented.

To discuss the clinical effects of external fixator combined with limited internal fixation in the treatment of pediatric distal femur fractures. From January 2008 to June 2014, 17 children of distal femur fractures were treated by external fixator combined with limited internal fixation. There were 12 males and 5 females, aged from 6 to 13 years old with an average of 10.2 years, ranged in the course of disease from 1 h to 2 d. Preoperative diagnoses were confirmed by X-ray films in all children. There were 11 patients with supracondylar fracture , and 6 patients with intercondylar comminuted fracture. According to AO/ASIF classification, 9 fractures were type A1, 5 cases were type A2,and 3 cases were type C1. The intraoperative and postoperative complications, postoperative radiological examination, lower limbs length and motion of knee joints were observed. Knee joint function was assessed by KSS score. All the patients were followed up from 6 to 38 months with an average of 24.4 months. No nerve or blood vessel injury was found. One case complicated with the external fixation loosening, 2 cases with the infection of pin hole and 3 cases with the leg length discrepancy. Knee joint mobility and length measurement (compared with the contralateral), the average limited inflexion was 10 degrees (0 degrees to 20 degrees), the average limited straight was 4 degrees (0 degrees to 10), the average varus or valgus angle was 3 degrees (0 degrees to 5 degrees). KSS of the injured side was (96.4 +/- 5.0) points at final follow-up, 16 cases got excellent results and 1 good. All fractures obtained healing and no epiphyseal closed early was found. External fixator combined with limited internal fixation has advantages of simple operation, reliable fixation, early functional exercise in treating pediatric distal femurs fractures.

To evaluate the efficacy (length of stay in the emergency department and failure rate of Bier's block) and safety profile (death and major complications) of Bier's block in its use for manipulation and reduction of paediatric forearm fractures. This is a retrospective cohort study of pediatric patients in KKWomen's and Children's Hospital Children's Emergency Department with forearm fractures between Jan 2003 and Dec 2014 who underwent manipulation and reduction using Bier's block. Demographic data, time from registration to discharge, major complications and success rate were collated in a standardized data collection form. A subanalysis of the Bier's block group from 2009 to 2014 was performed and compared to a corresponding data set of paediatric patients who underwent manipulation and reduction of forearm fractures using ketamine for procedural sedation from 2009 to 2014. 1781 cases of paediatric forearm fractures were analysed. The mean age of patients in the Bier's block group was 12.0 years (range 5.5-17.8 years old). Of all patients undergoing Bier's block, 1471 out of 1781 patients were male (82.7%). The mean length of stay (LOS) in the department was 168±72min, measured from time of registration till departure. From our subanalysis of data from 2009 to 2014, the mean LOS for the Bier's block group was shorter - 170min compared to 238min for the ketamine group (P block which required a repeat procedural sedation using ketamine. 96% of patients who underwent Bier's block were discharged with an outpatient orthopaedic appointment. There were no deaths or major complications identified in our study. Bier's block is a safe technique for reduction of fractures when used in the appropriate population and fracture types, with a low failure rate and no major complications including death. Compared to the ketamine group, it has a shorter length of stay in the emergency department. We recommend the adoption of this practice for manipulation and reduction of

Participation in sports is a popular activity for children across the country. Prevention of sports-related injuries can be improved if details of injuries are documented and studied. A retrospective medical record review of injuries that occurred as a direct result of sports participation (both organized and non-organized play) from November 2006 to November 2007. Because the vast majority of injuries were a result of participation in football or basketball, these injuries were focused upon. The injuries specifically examined were closed head injury (CHI), lacerations and fractures. There were 350 football and 196 basketball injuries (total 546). Comparing injuries between the two groups fractures were found to be more prevalent in football compared to basketball (z = 2.14; p = 0.03; 95%CI (0.01, 0.16)). Lacerations were found to be less prevalent among helmeted patients than those without helmets. (z = 2.39; p = 0.02; 95%CI (-0.17,-0.03)). CHI was more prevalent among organized play compared to non-organized (z = 3.9; pfootball related visits, organized play had a higher prevalence of injury compared to non-organized play (z = 2.87; p = 0.004; 95%CI (0.04.0.21)). No differences in fracture or laceration prevalence were found between organized and non-organized play. Football and basketball related injuries are common complaints in a pediatric Emergency Department. Frequently seen injuries include CHI, fractures and lacerations. In our institution, fractures were more prevalent among football players and CHI was more prevalent among organized sports participants.

To determine the pattern of occurrence of mandibular fractures in the pediatric population in Portugal. This retrospective study reviews the records of patients 18 years of age or younger from the 10-year period 1993 to 2002. Age, gender, anatomic site, cause of the accident, weekly and monthly variation, location and type of fractures, presence and location of associated injuries, treatment methods, and complications were reviewed. During this 10-year period, 521 patients with 681 mandibular fractures were treated. Motor-vehicle accident (MVA) was the most common (53.9% patients) cause of fracture. Almost half of the patients (48.8%) were in the oldest age group (16 to 18 years old). The condyle of the mandible was involved in 31.0% of the fractures. Maxillomandibular (MMF) fixation was used in 534 (78.4%) fractures. Overall mortality in this series was 0.6% (3 patients); mortality was caused by multiple traumas, mainly head trauma. There is a need to reinforce legislation aimed to prevent MVA and the total enforcement of existing laws to reduce maxillofacial injuries among children and adolescents.

The majority of pediatric fractures are treated in casts due to the child's ability to heal rapidly and remodel. Unplanned cast changes are a time and economic burden with potentially adverse effects on fracture management. The purpose of this study is to document the incidence, etiology, and complications related to unplanned cast changes. A prospective study was conducted over a 6-month period to determine the incidence of unplanned cast changes. All casts applied were nonwaterproof. Data collected include the reason for cast placement, type of cast placed, duration of wear before the unplanned change, reason for the unplanned change, experience level of the original cast applicator, and cast-related complications. A total of 1135 casts were placed with 58% placed by a resident, 38% by a cast technician, 2% by a physician's assistant, and 2% by an attending physician. Sixty casts (5.3%) required an unplanned change including 19 short-arm casts, 18 short-leg casts, 17 long-arm casts, 4 thumb spica casts, and 2 long-leg casts. The average duration from cast application until the unplanned change was 13 days. Twenty-eight (47%) were changed for wetness, 20 (33%) for wear/breakage, 2 (3%) for skin irritation, and 10 (17%) for other reasons including objects in the cast and patient self-removal. Two patients had superficial skin infections requiring oral antibiotics. No fracture reductions were lost secondary to an unplanned cast change. The need for an unplanned cast change did not correlate with the level of experience of the applicator. Most unplanned cast changes were the result of patient nonadherence to instructions and not related to cast application technique. Improved patient and family education regarding cast care may reduce the frequency of unplanned cast changes, thus reducing an economic and time burden on the health care system. Level II--prognostic study.

Different studies using synthetic fractures and various fluids have yielded different relative permeability-saturation relations. This study aimed to extend the understanding of multiphase flow by conducting nitrogen-water relative permeability experiments on a naturally-fractured rock from The Geysers geothermal field. The steady-state approach was used. However, steady state was achieved only at the endpoint saturations. Several difficulties were encountered that are attributed to phase interference and changes in fracture aperture and surface roughness, along with fracture propagation/initiation. Absolute permeabilities were determined using nitrogen and water. The permeability values obtained change with the number of load cycles. Determining the absolute permeability of a core is especially important in a fractured rock. The rock may change as asperities are destroyed and fractures propagate or st rain harden as the net stresses vary. Pressure spikes occurred in water a solute permeability experiments. Conceptual models of an elastic fracture network can explain the pressure spike behavior. At the endpoint saturations the water relative permeabilities obtained are much less than the nitrogen gas relative permeabilities. Saturations were determined by weighing and by resistivity calculations. The resistivity-saturation relationship developed for the core gave saturation values that differ by 5% from the value determined by weighing. Further work is required to complete the relative permeability curve. The steady-state experimental approach encountered difficulties due to phase interference and fracture change. Steady state may not be reached until an impractical length of time. Thus, unsteady-state methods should be pursued. In unsteady-state experiments the challenge will be in quantifying rock fracture change in addition to fluid flow changes.

Pediatric forearm shaft fractures are the third most common fracture in children, and the forearm is the third most mobile joint in the body (with a nearly 180 degree arc of motion). The goals of treatment are aimed squarely at achieving satisfactory anatomic alignment (within defined parameters) as the consequences of malunion can be permanent forearm stiffness and deformity. Nonoperative treatment approaches still dominate care of the youngest age groups while surgical intervention has become increasingly common in older children. This article will offer evidence and experience-based tips intended to benefit the community orthopedic surgeon caring for children during the course of their on-call duties.

To report and assess the usefulness of ultrasound (US) findings for occult fractures of growing bones. For six years, US scans were performed in children younger than 15 years who were referred with trauma-related local pain and swelling of the extremities. As a routine US examination, the soft tissue, bones, and adjacent joints were examined in the area of discomfort, in addition to the asymptomatic contralateral extremity for comparison. Twenty-five occult fractures in 25 children (age range, five months-15 years; average age, 7.7 years) were confirmed by initial and follow-up radiograms, additional imaging studies, and clinical observation longer than three weeks. The most common site of occult fractures was the elbow (n = 9, 36%), followed by the knee (n = 7, 28%), ischium (n = 4, 16%), distal fibula (n = 3, 12%), proximal femur (n = 1, 4%), and humeral shaft (n = 1, 4%). On the retrograde review of the routine radiographs, 13 out of the 25 cases showed no bone abnormalities except for various soft tissue swelling. For the US findings, cortical discontinuity (direct sign of a fracture) was clearly visualized in 23 cases (92%) and was questionable in two (8%). As auxiliary US findings (indirect signs of a fracture), step-off deformities, tiny avulsed bone fragments, double-line appearance of cortical margins, and diffuse irregularity of the bone surfaces were identified. Performing US for soft tissue and bone surfaces with pain and swelling, with or without trauma history in the extremities, is important for diagnosing occult or missed fractures of immature bones in pediatric-aged children.

The difficulties in surgical treatment of pilon fractures of the finger include fragment reconstitution and posthealing stiffness. In adults, external fixation with traction and early active range of motion (AROM)/passive range of motion (PROM) during healing is considered necessary for avoiding joint stiffness and attaining realignment. The authors present a unique approach to pediatric pilon fractures that uses open reduction and multivector external fixation with delayed AROM/PROM. Initial immobilization and significant traction allowed for joint realignment and prevented noncompliance with staged distraction. The authors believe this immobilization leads to a superior outcome because, unlike adults, children tend to avoid stiffness and a larger distraction force allowed for sufficient joint realignment to regain range of motion (ROM). A right-handed 13-year-old boy sustained a right ring finger fracture and presented 12 days later. Radiographs revealed a comminuted Salter-Harris 4 fracture of the middle phalanx. The patient underwent open reduction and placement of multivector external fixation using a pediatric mandibular distractor/fixator. Significant traction was applied to distract the finger to length. Hardware was removed 6 weeks postoperatively and AROM was initiated after splinting. The patient started PROM 8 weeks postoperatively. Strengthening was initiated 2 weeks later. ROM improved and rehabilitation was continued. The patient exhibited nearly equal grip strength 12 weeks postoperatively. At 14 months follow-up, radiographs showed complete healing and joint realignment. There was no deformity or pain and finger length was restored. Management of pediatric pilon fractures is rarely described and presents unique considerations. Early-stage traction and immobilization using a multivector mandibular fixator/distractor is suitable in a child because noncompliance is avoided and there is a decreased risk for stiffness.

Oral and maxillofacial surgeons must constantly weigh the risks of surgical intervention for pediatric mandible fractures against the wonderful healing capacity of children. The majority of pediatric mandibular fractures can be managed with closed techniques using short periods of maxillomandibular fixation or training elastics alone. Generally, the use of plate- and screw-type internal fixation is reserved for difficult fractures. This article details general and special considerations for this surgery including: craniofacial growth & development, surgical anatomy, epidemiology evaluation, various fractures, the role rigid internal fixation and the Risdon cable in pediatric maxillofacial trauma. It concludes with suggestions concerning long-term follow-up care in light of the mobility, insurance obstacles, and family dynamics facing the patient population.

Pediatric supracondylar humerus fractures are the most common elbow fractures in pediatric patients. Surgical fixation using pins is the primary treatment for displaced fractures. Pin site infections may follow supracondylar humerus fracture fixation; the previously reported incidence rate in the literature is 2.34%, but there is significant variability in reported incidence rates of pin site infection. This study aims to define the incidence rate and determine pre-, peri-, and postoperative factors that may contribute to pin site infection following operative reduction, pinning, and casting. A retrospective chart analysis was performed over a one-year period on patients that developed pin site infection. A cast care form was added to Nemours' electronic medical records (EMR) system (Epic Systems Corp., Verona, WI) to identify pin site infections for retrospective review. The cast care form noted any inflamed or infected pins. Patients with inflamed or infected pin sites underwent a detailed chart review. Preoperative antibiotic use, number and size of pins used, method of postoperative immobilization, pin dressings, whether postoperative immobilization was changed prior to pin removal, and length of time pins were in place was recorded. A total of 369 patients underwent operative reduction, pinning, and casting. Three patients developed a pin site infection. The pin site infection incidence rate was 3/369=0.81%. Descriptive statistics were reported for the three patients that developed pin site infections and three patients that developed pin site complications. Pin site infection development is low. Factors that may contribute to the development of pin site infection include preoperative antibiotic use, length of time pins are left in, and changing the cast prior to pin removal.

Pediatric both-bone diaphyseal forearm fractures are commonly treated in a variety of clinical settings. Most often, closed reduction followed by immobilization leads to satisfactory results. However, in the adolescent population (10-16 years of age), forearm fractures are more challenging due to less remodeling potential. The purpose of this review was to provide an overview of the anatomy, biomechanics, and treatment options relevant to adolescent patients. A systematic review of peer-reviewed publications and abstracts related to the treatment for pediatric both-bone diaphyseal forearm fractures in adolescents was carried out. Forearm fractures in the pediatric population are most common following indirect blows to the forearm. When treating these fractures using closed reduction, it is important to recognize the muscular attachments of the forearm. In roughly 70-90% of cases, closed reduction leads to adequate alignment. In all cases, return to function is the primary goal; however, exact alignment parameters remain controversial. In the adolescent population, surgical treatment has risen substantially in the last few decades. Intramedullary nailing and open reduction using plate fixation are the two most common operative techniques. Unfortunately, recent results have shown that nonunion, malunion, and overall complication rates are higher in older pediatric patients. Moreover, no consensus exists regarding one technique over another. Both-bone diaphyseal fractures in the adolescent population present unique challenges regarding optimal treatment, especially when considering surgical intervention. Further research is necessary to better understand indications for specific surgical treatment.

To characterize the types and external causes of pediatric injury-related visits (IRVs) to emergency departments (EDs), in particular, sports-related injuries. To compare the characteristics of children with IRVs with those with non-IRVs, specifically, differences in IRV rates by race and ethnicity and by health insurance. This was a stratified random-sample survey of EDs in the National Hospital Ambulatory Medical Care Survey (NHAMCS), including all IRVs for patients less than 19 years of age in 1998 (n = 2,656). National estimates of pediatric IRVs were obtained using the assigned patient visit weights in the NHAMCS databases and SUDAAN analyses. Measures of association between predictor variables (patient and health insurance characteristics) and whether a child had an IRV were calculated using multivariate logistic regression analyses to determine adjusted odds ratios with 95% confidence intervals. Pediatric IRVs accounted for more than 11 million ED visits annually. The most common diagnoses for IRVs were open wounds, contusions, sprains and strains, and fractures and dislocations. The leading external causes of IRVs were sports-related injuries, accidental falls, being struck by objects, and motor vehicle collisions. Children with IRVs differed from those who presented for non-IRVs in many characteristics: they were more likely to be male, to be older, to be of white race, and to have private insurance, and less likely to be of Asian or Hispanic ethnicity. Sports and recreation are the leading external causes of pediatric IRVs to EDs in the United States. There are different patterns of IRVs according to gender, age, race, ethnicity, and insurance. Identification of specific patterns of injury is necessary for the design of effective prevention strategies.

2015-01-01

The use of computed tomography (CT) in clinical practice has been increasing rapidly, with the number of CT examinations performed in adults and children rising by 10% per year in England. Because the radiology community strives to reduce the radiation dose associated with pediatric examinations, external factors, including guidelines for pediatric head injury, are raising expectations for use of cranial CT in the pediatric population. Thus, radiologists are increasingly likely to encounter pediatric head CT examinations in daily practice. The variable appearance of cranial sutures at different ages can be confusing for inexperienced readers of radiologic images. The evolution of multidetector CT with thin-section acquisition increases the clarity of some of these sutures, which may be misinterpreted as fractures. Familiarity with the normal anatomy of the pediatric skull, how it changes with age, and normal variants can assist in translating the increased resolution of multidetector CT into more accurate detection of fractures and confident determination of normality, thereby reducing prolonged hospitalization of children with normal developmental structures that have been misinterpreted as fractures. More important, the potential morbidity and mortality related to false-negative interpretation of fractures as normal sutures may be avoided. The authors describe the normal anatomy of all standard pediatric sutures, common variants, and sutural mimics, thereby providing an accurate and safe framework for CT evaluation of skull trauma in pediatric patients.

This study aimed to address 2 important aspects of temporal pattern in alcohol-related facial fractures: (1) comparison of temporal pattern of alcohol-related facial fracture (alcohol group) presentation with non-alcohol-related fracture (non-alcohol group) presentation; (2) temporal pattern of patient demographic characteristics, injury characteristics, and surgical management in the alcohol group presentation. This study retrospectively examined the Victorian admitted episodes data set (VAED) for the years 2010 to 2013. VAED is a standardized set of data collected during all hospital presentations in Victoria. The study found higher incidence of alcohol-related facial fracture presentations during weekends and during the summer and spring months compared with non-alcohol-related fractures (statistically significant). Alcohol-related facial fractures are more likely to involve male patients in the 20- to 29-year age group, occur as a result of interpersonal violence, and require shorter hospital stays during weekend admissions (statistically significant). No statistically significant relationship has been observed in seasonal variation across all variables. This study found distinct characteristics in temporal distribution of alcohol-related facial fractures. These characteristics are, in particular, significant in weekend trauma admissions. Such information is important in workforce planning, resource distribution, and implementation of injury prevention programs. Copyright © 2017 Elsevier Inc. All rights reserved.

Facial fractures in children are rare. Lack of pneumatization, fat pockets, mixed dentition, contribute to the elasticity and bone stability. When mandibular fractures occur in children, most often involve the condyle by indirect trauma. Such fractures are the center of discussion on the form of treatment if this should be performed conservatively, or held the reduction and fixation of the fracture with surgical exposure of the fragments. In condylar fractures in children, in most patients, the proposed treatment is closed reduction. Treatment with open reduction and fixation has its specific indications. In this case, the authors report a patient cycling accident victim, with cut-contusion injury in ment with limited mouth opening and left condylar fracture with medial rotation. The treatment was the reduction and fixation of fragments by open process.

Sternal fractures are rare injuries in children. The rarity of this injury is likely due to both the relative plasticity of the pediatric thorax and to the difficulty in establishing a radiographic diagnosis without dedicated views. Current literature suggests that this injury in young children is highly specific for abusive injury.Hypothesis. Sternal fractures are not highly specific for abusive injury. Materials and methods. This was a retrospective radiographic and clinical chart review of all documented sternal fractures over an 11-year period at a large pediatric hospital.Results. Of 12 children with sternal fractures identified, four were {<=}2 years of age and eight were {>=}3 years of age. The mechanism of injury was suspicious for child abuse in two children. Both of these children were {<=}2 years of age. In one toddler, an unwitnessed injury resulted in extensive initial familial anxiety until abusive injury was excluded.Conclusion. Sternal fractures are unusual injuries, yet they, in themselves, are not highly specific for abusive injury. (orig.)

Mandible fractures account for a significant portion of maxillofacial injuries and the evaluation, diagnosis, and management of these fractures remain challenging despite improved imaging technology and fixation techniques. Understanding appropriate surgical management can prevent complications such as malocclusion, pain, and revision procedures. Depending on the type and location of the fractures, various open and closed surgical reduction techniques can be utilized. In this article, the authors review the diagnostic evaluation, treatment options, and common complications of mandible fractures. Special considerations are described for pediatric and atrophic mandibles.

To investigate the clinical results of occlusal splint in the treatment of sagittal fracture of mandibular condyle (SFMC) in children. Thirty-nine patients (48 condyles)aged 3-8 years with sagittal fracture of mandibular condyle were included in this study. All the patients were treated by occlusal splint.Slight open occlusion was maintained by occlusal splint for 3-6 months. Clinical and radiological examination was performed six mouths and every year after treatment. Good mandibular function was observed in 39 patients. Maximal mouth opening over 35 mm was achieved at 6 months. But 11 of the 39 patients presented with deviation on mouth opening at 6 months. The radiology showed an complete remodeling in 32 condyles (28 patients) and partial remodeling in 16 condyles (11 patients). Poor remodelling was not observed in any patients. Good clinical results can be obtained by using occlusal splint in the treatment of pediatric sagittal fracture of mandibular condyle.

Self-balancing electric scooters, commonly known as hoverboards, are a new and popular consumer item with recognized fall hazards. The spectrum of injuries associated with hoverboard use has not been studied. The purpose of this study is to determine the spectrum of radiologically apparent injuries associated with hoverboard use. We retrospectively reviewed all imaging studies interpreted at our institution for hoverboard-related injuries during an 8-month period. We recorded patient demographics and injury characteristics. Thirty-two of the 47 pediatric patients imaged for hoverboard-related injury had radiologically detectable injuries, all fractures. Fifty percent of these 32 patients were female and 50% were male, with a mean age of 12.4 years. There were 42 fractures total, all involving the appendicular skeleton, with 74% in the upper extremities and 26% in the lower extremities. Thirty-eight percent of the fractures involved the physis. A distinct injury pattern was seen in three patients who sustained open distal phalanx juxta-epiphyseal fractures. Most of the fractures sustained during hoverboard use are commonly seen in everyday pediatric radiology practice, with an overall pattern paralleling that reported in association with skateboard use. However an otherwise uncommon fracture, the distal phalanx juxta-epiphyseal fracture, was identified in association with hoverboard use, and this finding has important treatment implications including need for irrigation and debridement, antibiotic therapy, and potential surgical fixation.

Pelvic fractures are a marker of severe injury, mandating a thorough investigation for the presence of associated injuries. Anatomical and physiological differences between adults and children may lead to a different impact of pelvic fractures on these populations. The purpose of this study is to compare pelvic fractures between pediatric and adult blunt trauma victims, mainly regarding their severity and associated intraabdominal injuries. A retrospective study involving blunt trauma patients suffering pelvic fractures, according to the records of the Israeli National Trauma Registry. Patients included children, aged 0-14years, and adults between 15 and 64years. The presence and severity of associated injuries were assessed. Overall, 7621 patients aged 0-64years were identified with pelvic fractures following blunt trauma. The incidence of pelvic fractures in children was (0.8%), as compared to 4.3% in adults, p 25. Adults sustained significantly more moderate to severe pelvic fractures (AIS≥3) than children (26.7% vs. 17.4%, psplenic and hepatic injuries (p=0.026, p=0.0004, respectively). Among children, a similar correlation was not demonstrated. Adults involved in blunt trauma are more likely to sustain pelvic fractures, and these are generally more severe fractures, as compared to children suffering from blunt trauma. Nonetheless, mortality rates were found similar in both groups. The only associated injury with statistically significant difference in incidence among the two groups was rectal injury. In adults, but not in children, higher grade pelvic fractures correlated with more severe concomitant splenic or hepatic injuries. The level of evidence for this study is III (3).

2018-04-01

Pediatric digital necrosis resulting in revision amputation is a devastating outcome following digital dressing application. We report a series of 4 pediatric patients (age: 21 months-11 years) who presented for surgical consultation related to digital ischemia and irreversible necrosis following the application of Coban digital dressings. A review of the literature demonstrated that such injuries had not previously been described. In our case series, Coban dressing was utilized as a deterrent for thumb sucking, fingertip tuft fractures with nail bed lacerations, and a phalanx fracture secondary to crush injury. All 4 children suffered digital necrosis secondary to Coban dressings and ultimately required revision amputation. We discuss risks factors, application practices, and strategies to minimize complications with digital dressings in the pediatric population with the intent of creating awareness among hand surgeons to help promote safe practices and improve patient outcomes.

To summarize compensation results from the 2015 Society of Pediatric Psychology (SPP) Workforce Survey and identify factors related to compensation of pediatric psychologists. All full members of SPP ( n  = 1,314) received the online Workforce Survey; 404 (32%) were returned with usable data. The survey assessed salary, benefits, and other income sources. The relationship between demographic and employment-related factors and overall compensation was explored.   Academic rank, level of administrative responsibility, and cost of living index of employment location were associated with compensation. Compensation did not vary by gender; however, women were disproportionately represented at the assistant and associate professor level. Compensation of pediatric psychologists is related to multiple factors. Longitudinal administration of the Workforce Survey is needed to determine changes in compensation and career advancement for this profession over time. Strategies to increase the response rate of future Workforce Surveys are discussed. © The Author 2017. Published by Oxford University Press on behalf of the Society of Pediatric Psychology.

Kennedy, Robert M; Luhmann, Jan D; Luhmann, Scott J

2004-01-01

Orthopedic fractures and joint dislocations are among the most painful pediatric emergencies. Safe and effective management of fracture-related pain and anxiety in the emergency department reduces patient distress during initial evaluation and often allows definitive management of the fracture. No consensus exists on which pharmacologic regimens for procedural sedation/analgesia are safest and most effective. For some children, control of fracture pain is the primary goal, whereas for others, relief from anxiety is an additionally important objective. Furthermore, strategies for the management of fracture pain may vary by fracture location and patient characteristics; thus, no single regimen is likely to provide the best means of analgesia and anxiolysis for all patients. Effective analgesia can be provided by local or regional anesthesia, such as hematoma, Bier, or nerve blocks. Alternatively, induction of deep sedation with analgesic agents such as ketamine or fentanyl, often combined with sedative-anxiolytic agents such as midazolam, may be used to manage distress associated with fracture reduction. A combination of local anesthesia with moderate sedation, for example nitrous oxide, is another attractive option.

The recreational use of trampolines has increased dramatically during the last 10 years. There has been a striking increase in the number of children presenting to fracture clinics with injuries associated with trampoline use. This increase in trampoline injuries has been reported in North America, but there has been a paucity of research in this area in Europe. We prospectively recorded details of patients presenting to our institution, Our Lady's Children's Hospital, Crumlin (Dublin, Ireland), during the busy summer months of June, July, and August 2005. Details recorded included type and mechanism of injury, the mode of referral, treatment, inpatient days, outpatient visits, specific details relating to trampoline safety, and an analysis of the cost of medical care. There were 101 patients treated for trampoline-related injuries in 3 months from June to August 2005. This represented 1.5% of the total attendances to the emergency department. The average age was 8.5 years (range, 1.4-17.4 years). There were 55 fractures, 38 soft tissue injuries, 5 head injuries, and 5 neck injuries, with an average Pediatric Trauma Score of 11.4. Fifty seven percent (58/101) of patients were on the trampoline with at least 1 other person. Twenty patients (19.8%) were admitted to hospital requiring 71 inpatient days. Twelve patients were treated in theatre. There were 163 fracture clinic visits, 212 x-rays, and 2 magnetic resonance imaging scans. Trampolines are a high-risk activity with the potential for significant orthopaedic injury. In Ireland, we have recently seen a dramatic increase in pediatric trampoline-related injuries mirroring the trend in the United States during the last 10 to 15 years. We found that more than 1 individual on a trampoline is a major risk factor for injury, where the lightest person is 14 times more likely to be injured than the heavier. The lighter person also has a greater chance of being injured with smaller numbers on the trampoline. We reiterate

Analytical Estimation of Water-Oil Relative Permeabilities through Fractures

Full Text Available Modeling multiphase flow through fractures is a key issue for understanding flow mechanism and performance prediction of fractured petroleum reservoirs, geothermal reservoirs, underground aquifers and carbon-dioxide sequestration. One of the most challenging subjects in modeling of fractured petroleum reservoirs is quantifying fluids competition for flow in fracture network (relative permeability curves. Unfortunately, there is no standard technique for experimental measurement of relative permeabilities through fractures and the existing methods are very expensive, time consuming and erroneous. Although, several formulations were presented to calculate fracture relative permeability curves in the form of linear and power functions of flowing fluids saturation, it is still unclear what form of relative permeability curves must be used for proper modeling of flow through fractures and consequently accurate reservoir simulation. Basically, the classic linear relative permeability (X-type curves are used in almost all of reservoir simulators. In this work, basic fluid flow equations are combined to develop a new simple analytical model for water-oil two phase flow in a single fracture. The model gives rise to simple analytic formulations for fracture relative permeabilities. The model explicitly proves that water-oil relative permeabilities in fracture network are functions of fluids saturation, viscosity ratio, fluids density, inclination of fracture plane from horizon, pressure gradient along fracture and rock matrix wettability, however they were considered to be only functions of saturations in the classic X-type and power (Corey [35] and Honarpour et al. [28, 29] models. Eventually, validity of the proposed formulations is checked against literature experimental data. The proposed fracture relative permeability functions have several advantages over the existing ones. Firstly, they are explicit functions of the parameters which are known for

The goal in this review was to summarize the results of clinical neuroimaging studies performed in patients with sports-related concussion (SRC) who were referred to a multidisciplinar ypediatric concussion program. The authors conducted a retrospective review of medical records and neuroimaging findings for all patients referred to a multidisciplinary pediatric concussion program between September 2013 and July 2014. Inclusion criteria were as follows: 1) age ≤ 19 years; and 2) physician-diagnosed SRC. All patients underwent evaluation and follow-up by the same neurosurgeon. The 2 outcomes examined in this review were the frequency of neuroimaging studies performed in this population (including CT and MRI) and the findings of those studies. Clinical indications for neuroimaging and the impact of neuroimaging findings on clinical decision making were summarized where available. This investigation was approved by the local institutional ethics review board. A total of 151 patients (mean age 14 years, 59% female) were included this study. Overall, 36 patients (24%) underwent neuroimaging studies, the results of which were normal in 78% of cases. Sixteen percent of patients underwent CT imaging; results were normal in 79% of cases. Abnormal CT findings included the following: arachnoid cyst (1 patient), skull fracture (2 patients), suspected intracranial hemorrhage (1 patient), and suspected hemorrhage into an arachnoid cyst (1 patient). Eleven percent of patients underwent MRI; results were normal in 75% of cases. Abnormal MRI findings included the following: intraparenchymal hemorrhage and sylvian fissure arachnoid cyst (1 patient); nonhemorrhagic contusion (1 patient); demyelinating disease (1 patient); and posterior fossa arachnoid cyst, cerebellar volume loss, and nonspecific white matter changes (1 patient). Results of clinical neuroimaging studies are normal in the majority of pediatric patients with SRC. However, in selected cases neuroimaging can provide

Atypical femoral fractures related to bisphosphonate therapy

Full Text Available Bisphosphonates (BP are a commonly prescribed class of drugs for the prevention of osteoporosis-related fractures. Paradoxically, however, they have recently been linked to atypical fractures in the shaft of the femur. Since many physicians including radiologists, are not aware of this entity, the incidence is likely underreported. These fractures usually occur in the sub-trochanteric region of the femur in the setting of low-energy trauma. It starts as a fracture line involving the lateral cortex and then progresses medially to give rise to a complete fracture. The fracture line is usually transverse, and there is a medial spike associated with a complete fracture. These fractures can be bilateral. Awareness of these atypical fractures and their radiological appearance should enable their early and accurate detection and thus lead to specific treatment.

The ideal type of immobilization for nondisplaced pediatric elbow fractures has not been established. We hypothesized that the use of a long-arm cylinder made of soft cast material will result in similar outcomes to those obtained with a traditional long-arm hard cast. We randomly assigned 100 consecutive children who presented with a closed, nondisplaced, type I supracondylar humeral fracture or an occult, closed, acute elbow injury, to 1 of 2 groups: group A (n=50) received a long-arm, traditional fiberglass (hard) cast. Group B (n=50) received a long-arm, soft fiberglass cast. After 4 weeks, the cast was removed in group A by a member of our staff using a cast saw, and in group B by one of the patient's parents by rolling back the soft fiberglass material. We compared the amount of fracture displacement and/or angulation, recovery of range of motion, elbow pain, and patient satisfaction. There were no instances of unplanned removal of the cast by the patient or parent. No evidence of fracture displacement or angulation was seen in either group. The final carrying angle of the affected elbow was nearly identical of that of the normal, contralateral elbow in both groups (P=0.64). At the latest follow-up appointment, elbows in groups A and B had a similar mean arc of motion (156 vs. 154 degrees; P=0.45), and had achieved identical relative arc of motion of 99.6% and 99.5% of that of the normal, contralateral side, respectively (P=0.94). Main pain scores were low and comparable over the study period. All patients in both groups reported the highest rate of satisfaction at the eighth week of follow-up. The results indicate that children with nondisplaced supracondylar humeral fractures can be successfully managed with the use of a removable long-arm soft cast, maintaining fracture alignment and resulting in comparable rates of range of motion, pain, and patient satisfaction. The use of a removable immobilization that can reliably maintain fracture alignment and

The purpose of this investigation was to determine which of the following methods of fixation, percutaneous pinning (PP) or intramedullary nailing (IMN), was more cost-effective in the treatment of displaced pediatric proximal humeral fractures (PPHF). A retrospective cohort of surgically treated PPHF over a 12-year period at a single institution was performed. A decision analysis model was constructed to compare three surgical strategies: IMN versus percutaneous pinning leaving the pins exposed (PPE) versus leaving the pins buried (PPB). Finally, sensitivity analyses were performed, assessing the cost-effectiveness of each technique when infection rates and cost of deep infections were varied. A total of 84 patients with displaced PPHF underwent surgical stabilization. A total of 35 cases were treated with IMN, 32 with PPE, and 17 with PPB. The age, sex, and preoperative fracture angulation were similar across all groups. A greater percentage of open reduction was seen in the IMN and PPB groups (p = 0.03), while a higher proportion of physeal injury was seen in the PPE group (p = 0.02). Surgical time and estimated blood loss was higher in the IMN group (p exposed implants approached 55 %. Leaving pins exposed after surgical fixation of PPHF is more cost-effective than either burying pins or using intramedullary fixation.

Distal forearm fractures, one of the most common fractures seen in the pediatric population, are regularly treated by closed reduction and casting. Our study investigates the effectiveness of Gore-Tex-lined casting in maintaining the reduction of 100% displaced distal forearm fractures compared with traditional cotton-lined casts. We screened all patients from February 2007 to July 2009 who presented to Children's Hospital in Birmingham, AL with a distal radius fracture. Only patients with 100% displaced distal radius fractures were eligible to be assigned to either the cotton-lined or Gore-Tex-lined cast groups. Power analysis was performed to identify an adequate patient sample size. The mean maximum change between initial post-reduction x-rays and follow-up x-rays for anterior-posterior (AP) angulation, AP displacement, lateral angulation, and lateral displacement of the radius were calculated for both cotton and Gore-Tex groups. The rate of subsequent intervention and/or unacceptable results for each group was also analyzed. Seven hundred and twenty-two patients were treated with distal radius fractures at our hospital with 59 patients eligible for inclusion in our study. Thirty-six of our patients were treated with cotton-lined casts, and 23 patients were treated with Gore-Tex-lined cast. The mean maximum change in AP angulation, AP displacement, lateral angulation, and lateral displacement of the radius after initial reduction was 9.2 degrees, 6.9%, 13.9 degrees, and 13.6%, respectively, for the cotton-lined cast group and 7.7 degrees, 6.1%, 14.6 degrees, and 9.6%, respectively, for the Gore-Tex-lined cast group. There were no statistical differences between the means of the 4 measurements (P=0.33, 0.69, 0.73, and 0.10, respectively). There were also no significant differences between groups for final AP and lateral angulation and displacement. Subgroup analysis showed no significant differences in all measurements between cotton and Gore-Tex groups. Gore

Upper and lower extremity injuries are common in children, with an overall risk of fracture estimated at just under 1 in 5 children. Pediatric bone anatomy and physiology produce age specific injury patterns and conditions that are unique to children, which can make accurate diagnosis difficult for emergency clinicians. This issue reviews the etiology and pathophysiology of child-specific fractures, as well as common injuries of the upper and lower extremities. Evidence-based recommendations for management of pediatric fractures, including appropriate diagnostic studies and treatment, are also discussed.

Optimal management of pediatric mandible fractures demands that the practitioner balance reduction and fixation with preservation of growth potential and function. The ideal synthesis of these goals has not yet been defined. The authors catalogue their experience with pediatric mandible fractures at a major pediatric teaching hospital with reference to demographics, injury type, treatment, and outcomes to inform future management of these injuries. Demographics, management, and outcomes of pediatric mandible fractures presenting over 10 years at a pediatric trauma center were assessed. Cephalometric analysis was conducted. Relationships among demographics, fracture type, management, outcomes, and growth were explored. Two hundred fifteen mandible fractures in 120 patients younger than 18 years were analyzed (average follow-up, 19.5 months). The condylar head and neck were fractured most frequently. Operative management was significantly more likely for children older than 12 years (pfractures were significantly associated with a higher rate of adverse outcomes (pmandibular function by patient or surgeon. No significant growth differences existed on cephalometric analysis between our cohort and age- and sex-matched controls (p>0.05). This study reports the demographics, treatment, and early follow-up of a sizable cohort of pediatric mandible fractures. Management principles for these injuries are outlined. Although definitive recommendations must be withheld until longer follow-up is available, the data presented here show that the treatment protocols used at the authors' center have yielded largely uncompromised mandibular function and growth thus far.

To describe outcomes after surgical management of pediatric elbow dislocation with incarceration of the medial epicondyle. We conducted a retrospective case review of 11 consecutive children and adolescents with an incarcerated medial epicondyle fracture after elbow dislocation. All patients underwent open reduction internal fixation using a similar technique. We characterized outcomes at final follow-up. Average follow-up was 14 months (range, 4-56 mo). All patients had clinical and radiographic signs of healing at final follow-up. There was no radiographic evidence of loss of reduction at intervals or at final follow-up. There were no cases of residual deformity or valgus instability. Average final arc of elbow motion was 4° to 140°. All patients had forearm rotation from 90° supination to 90° pronation. Average Mayo elbow score was 99.5. Four of 11 patients had ulnar nerve symptoms postoperatively and 1 required a second operation for ulnar nerve symptoms. In addition, 1 required a second operation for flexion contracture release with excision of heterotopic ossification. Three patients had ulnar nerve symptoms at final follow-up. Two of these had mild paresthesia only and 1 had both mild paresthesia and weakness. Our results suggest that open reduction internal fixation of incarcerated medial epicondyle fractures after elbow dislocation leads to satisfactory motion and function; however, the injury carries a high risk for complications, particularly ulnar neuropathy.

2015-06-01

The purpose of this study was to assess the effects of the durations of cast immobilization and non-weight-bearing periods, and decreases in vigorous physical activity (VPA) on bone mineral parameters in a pediatric population treated for a lower-limb fracture. Fifty children and teenagers who had undergone a cast-mediated immobilization for a leg or ankle fracture were prospectively recruited. The durations of cast immobilization and non-weight-bearing periods were recorded for each participant. Dual-energy x-ray absorptiometry scans were performed at the time of fracture treatment (baseline) and at cast removal. Physical activity during cast immobilization was assessed using accelerometers. A strong negative correlation was found between the total duration of cast immobilization and decreases in both calcaneal bone mineral density (BMD) (r=-0.497) and total lower-limb bone mineral content (BMC) (r=-0.405). A strong negative correlation was also noted between the durations of the non-weight-bearing periods and alterations in calcaneal BMD (r=-0.420). No apparent correlations were found between lower BMD and BMC and decreased VPA. Bone mineral loss was correlated to the total duration of cast immobilization for all measurement sites on the affected leg, whereas it was only correlated to the durations of non-weight-bearing periods for calcaneal BMD and total lower-limb BMC. However, no correlations were noted between bone mineral loss and decreased VPA.

Worldwide fracture rates are increasing as a result of the aging population, and prevention, both primary and secondary, is an important public health goal. Therefore, we systematically analyzed risk factors in subjects with a recent clinical fracture. All men and women over fifty years of age who had been treated in the emergency department of, or hospitalized at, our institution because of a recent fracture during a one-year period were offered the opportunity to undergo an evidence-based bone and fall-related risk-factor assessment and bone densitometry. The women included in this study were also compared with a group of postmenopausal women without a fracture history who had been included in another cohort study. Of the 940 consecutive patients, 797 (85%) were eligible for this study and 568 (60%) agreed to participate. The prevalence of fall-related risk factors (75% [95% confidence interval = 71% to 78%]; n = 425) and the prevalence of bone-related risk factors (53% [95% confidence interval = 49% to 57%]; n = 299) at the time of fracture were higher than the prevalence of osteoporosis (35% [95% confidence interval = 31% to 39%]; n = 201) as defined by a dual x-ray absorptiometry T score of fall and bone-related risk factors were present irrespective of the fracture location, patient age, or gender. An overlap between bone and fall-related risk factors was found in 50% of the patients. After adjusting for age, weight, and height, we found that women with a fracture more frequently had a diagnosis of osteoporosis (odds ratio = 2.9; 95% confidence interval = 2.0 to 4.1) and had a more extensive history of falls (odds ratio = 4.0; 95% confidence interval = 2.7 to 5.9) than did the postmenopausal women without a fracture history. Men and women over fifty years of age who had recently sustained a clinical fracture had, at the time of that fracture, bone and fall-related risk factors that were greater than the risk predicted by the presence of osteoporosis.

Mandibular fracture, specifically in the symphysis and body regions combined, is the most common facial fracture requiring hospitalization in North America. The primary treatment objective is to restore form and function by achieving anatomic reduction and placing fixation that eliminates mobility of the bone fragments. Several treatment options and surgical techniques are available for performing closed or open reduction. Special considerations are necessary when treating pediatric patients and fractures of the edentulous mandible. Complications relating to the tooth and denture-bearing regions of the mandible include infection, nonunion, and neurosensory changes. Copyright © 2013 Elsevier Inc. All rights reserved.

Hwang, Kun; You, Sun Hye; Lee, Hong Sik

2009-05-01

In this paper, we report a retrospective study of 236 patients with facial bone fractures from various sports who were treated at the Department of Plastic and Reconstructive Surgery, Inha University Hospital, Incheon, South Korea, between February 1996 and April 2007. The medical records of these patients were reviewed and analyzed to determine the clinical characteristics and treatment of the sports-related facial bone fractures. The highest frequency of sports-related facial bone fractures was in the age group 11 to 20 years (40.3%); there was a significant male predominance in all age groups (13.75:1). The most common causes of the injury were soccer (38.1%), baseball (16.1%), basketball (12.7%), martial arts (6.4%), and skiing or snowboarding (11%). Fractures of the nasal bone were the most common in all sports; mandible fractures were common in soccer and martial arts, orbital bone fractures were common in baseball, basketball, and ice sports, and fractures of the zygoma were frequently seen in soccer and martial arts. The main causes of the sports injuries were direct body contact (50.8%), and the most commonly associated soft tissue injuries were found in the head and neck regions (92.3%). Nasal bone fractures were the most common (54.2%), and tripod fractures were the most common type of complex injuries (4.2%). The complication rate was 3.0%. Long-term epidemiological data regarding the natural history of sports-related facial bone fractures are important for the evaluation of existing preventative measures and for the development of new methods of injury prevention and treatment.

Utility of the AAOS Appropriate Use Criteria (AUC) for Pediatric Supracondylar Humerus Fractures in Clinical Practice.

2017-01-01

The American Academy of Orthopaedic Surgeons (AAOS) recently developed an Appropriate Use Criteria (AUC) for pediatric supracondylar humerus fractures (PSHF). The AUC is intended to improve quality of care by informing surgeon decision making. The aim of our study was to cross-reference the management of operatively treated PSHF with the AAOS-published AUC. The AUC for PSHF include 220 patient scenarios, based on different combinations of 6 factors. For each patient scenario, 8 treatment options are evaluated as "appropriate," "maybe appropriate," and "rarely appropriate." We retrospectively reviewed the medical charts and radiographs of all operatively treated PSHF at our hospital from January 2013 to December 2014 and determined the appropriateness of the treatment. Over the study period, 94 children (mean age: 5.2 y; 51 male, 43 female) were admitted with PSHF and underwent a surgical procedure (type IIA: 7, type IIB: 14, type III: 70, flexion type: 3). Only 8 of the 220 scenarios were observed in our patient cohort. The most frequent scenario was represented by a type III fracture, palpable distal pulse, no nerve injury, closed soft-tissue envelope, no radius/ulna fracture, and typical swelling. Of the 94 fractures, the AUC was "appropriate" for 84 cases and "maybe appropriate" for 9 cases. There was only 1 case of "rarely appropriate" management. Closed reduction with lateral pinning and immobilization was the most prevalent treatment option (58.5%). The rate of appropriateness was not affected by the operating surgeon. However, the definition of a case as emergent had a significant impact on the rate of appropriateness. Application of the AUC to actual clinical data was relatively simple. The majority of operatively treated PSHF (89.4%) were managed appropriately. With the introduction of electronic medical charts, an AUC application becomes attractive and easy for orthopaedic surgeons to utilize in clinical practice. However, validity studies of the AUC in

Conclusion: We report a case series of a fracture pattern resulting from the improper/unsafe use of a hoverboard. This type of fracture occurs with a tremendous load of energy. Although improper use was a factor, design fault also plays a role in causing the injury. Parent awareness and supervision are important to prevent such injuries.

Surveillance for work-related skull fractures in Michigan.

Science.gov (United States)

Kica, Joanna; Rosenman, Kenneth D

2014-12-01

The objective was to develop a multisource surveillance system for work-related skull fractures. Records on work-related skull fractures were obtained from Michigan's 134 hospitals, Michigan's Workers' Compensation Agency and death certificates. Cases from the three sources were matched to eliminate duplicates from more than one source. Workplaces where the most severe injuries occurred were referred to OSHA for an enforcement inspection. There were 318 work related skull fractures, not including facial fractures, between 2010 and 2012. In 2012, after the inclusion of facial fractures, 316 fractures were identified of which 218 (69%) were facial fractures. The Bureau of Labor Statistic's (BLS) 2012 estimate of skull fractures in Michigan, which includes facial fractures, was 170, which was 53.8% of those identified from our review of medical records. The inclusion of facial fractures in the surveillance system increased the percentage of women identified from 15.4% to 31.2%, decreased severity (hospitalization went from 48.7% to 10.6% and loss of consciousness went from 56.5% to 17.8%), decreased falls from 48.2% to 27.6%, and increased assaults from 5.0% to 20.2%, shifted the most common industry from construction (13.3%) to health care and social assistance (15.0%) and the highest incidence rate from males 65+ (6.8 per 100,000) to young men, 20-24 years (9.6 per 100,000). Workplace inspections resulted in 45 violations and $62,750 in penalties. The Michigan multisource surveillance system of workplace injuries had two major advantages over the existing national system: (a) workplace investigations were initiated hazards identified and safety changes implemented at the facilities where the injuries occurred; and (b) a more accurate count was derived, with 86% more work-related skull fractures identified than BLS's employer based estimate. A more comprehensive system to identify and target interventions for workplace injuries was implemented using hospital and

Pediatric considerations in craniofacial trauma.

Science.gov (United States)

Koch, Bernadette L

2014-08-01

In many respects, craniofacial trauma in children is akin to that in adults. The appearance of fractures and associated injuries is frequently similar. However, the frequencies of different types of fractures and patterns of injury in younger children vary depending on the age of the child. In addition, there are unique aspects that must be considered when imaging the posttraumatic pediatric face. Some of these are based on normal growth and development of the skull base and craniofacial structures, and others on the varying etiologies and mechanisms of craniofacial injury in children, such as injuries related to toppled furniture, nonaccidental trauma, all-terrain vehicle accidents, and impalement injuries.

Screening pelvic radiographs to rule out pelvic fractures are routinely used for the initial evaluation of pediatric blunt trauma. Recently, the utility of routine pelvic radiographs in certain subsets of patients with blunt trauma has been questioned. There is a growing amount of evidence that shows the clinical exam is reliable enough to obviate the need for routine screening pelvic radiographs in children. To identify variables that help predict the presence or absence of pelvic fractures in pediatric blunt trauma. We conducted a retrospective study from January 2005 to January 2010 using the trauma registry at a level 1 pediatric trauma center. We analyzed all level 1 and level 2 trauma victims, evaluating history, exam and mechanism of injury for association with the presence or absence of a pelvic fracture. Of 553 level 1 and 2 trauma patients who presented during the study period, 504 were included in the study. Most of these children, 486/504 (96.4%), showed no evidence of a pelvic fracture while 18/504 (3.6%) had a pelvic fracture. No factors were found to be predictive of a pelvic fracture. However, we developed a pelvic fracture screening tool that accurately rules out the presence of a pelvic fracture P = 0.008, NPV 99, sensitivity 96, 8.98 (1.52-52.8). This screening tool combines eight high-risk clinical findings (pelvic tenderness, laceration, ecchymosis, abrasion, GCS <14, positive urinalysis, abdominal pain/tenderness, femur fracture) and five high-risk mechanisms of injury (unrestrained motor vehicle collision [MVC], MVC with ejection, MVC rollover, auto vs. pedestrian, auto vs. bicycle). Pelvic fractures in pediatric major blunt trauma can reliably be ruled out by using our pelvic trauma screening tool. Although no findings accurately identified the presence of a pelvic fracture, the screening tool accurately identified the absence of a fracture, suggesting that pelvic radiographs are not warranted in this subset of patients.

The fractures of facial structures lead to great morbidity. Cross-sectional studies are needed to evaluate the current state of maxillofacial traumas. Thus, this study aims to evaluate these experiences and to compare these results with the current literature. The medical records of the maxillofacial fracture cases hospitalized between January 2004 and November 2011 were examined. The age, sex, etiology, fracture localization and treatment method for each case were documented. The affected facial bones were grouped as mandible, maxilla, zygoma, naso-orbitoethmoid complex (NOEC) and blow-out. Nasal fractures were excluded. The cases were assigned to 3 groups with respect to age (below 16, above 65 and between 17 and 64). The chi Square test was used to assess the significance of the difference in mandibular fracture rates in the pediatric population compared to others. The total number of cases was 152. The total number of fractures was 185. Of the 152 cases, 117 were male and 35 were female. The average age was 31.4 (±18.3), ranging between 2 and 81. Thirty-one cases were 16 years old or less. Nine cases were 65 years old or more. Mandibular and zygomatic fractures were the most prevalent fractures in the adult group. Mandibular fractures were significantly more common in the pediatric age group compared to rest of the population (X(2), pOpen reduction and internal fixation was the most frequently conducted treatment modality in all age groups. Retrospective studies are important for the projection of future prospects. In summary, our results indicate that pediatric fractures are mostly in the lower face and usually affect the condylar region, which is consistent with the literature.

Although surgical treatment of orbital floor fractures can be performed by many different approaches, the application of endoscopic modified medial maxillectomy (EMMM) for this condition has rarely been described in the literature. We report on a case of a 7-year-old boy with a trapdoor orbital floor fracture successfully treated with the application of EMMM. The patient suffered trauma to the right orbit floor and the inferior rectus was entrapped at the orbital floor. Initially, surgical repair via endoscopic endonasal approach was attempted. However, we were unable to adequately access the orbital floor through the maxillary ostium. Therefore, an alternative route of access to the orbital floor was established by EMMM. With sufficient visualization and operating space, the involved orbital content was completely released from the entrapment site and reduced into the orbit. To facilitate wound healing, the orbital floor was supported with a water-inflated urethral balloon catheter for 8 days. At follow-up 8 months later, there was no gaze restriction or complications associated with the EMMM. This case illustrates the efficacy and safety of EMMM in endoscopic endonasal repair of orbital floor fracture, particularly for cases with a narrow nasal cavity such as in pediatric patients.

Simulation-based education has been integrated into many orthopaedic residency programs to augment traditional teaching models. Here we describe the development and implementation of a combined didactic and simulation-based course for teaching medical students and interns how to properly perform a closed reduction and percutaneous pinning of a pediatric supracondylar humeral fracture. Subjects included in the study were either orthopaedic surgery interns or subinterns at our institution. Subjects all completed a combined didactic and simulation-based course on pediatric supracondylar humeral fractures. The first part of this course was an electronic (e)-learning module that the subjects could complete at home in approximately 40 minutes. The second part of the course was a 20-minute simulation-based skills learning session completed in the simulation center. Subject knowledge of closed reduction and percutaneous pinning of supracondylar humeral fractures was tested using a 30-question, multiple-choice, written test. Surgical skills were tested in the operating room or in a simulated operating room. Subject pre-intervention and post-intervention scores were compared to determine if and how much they had improved. A total of 21 subjects were tested. These subjects significantly improved their scores on both the written, multiple-choice test and skills test after completing the combined didactic and simulation module. Prior to the module, intern and subintern multiple-choice test scores were significantly worse than postgraduate year (PGY)-2 to PGY-5 resident scores (p < 0.01); after completion of the module, there was no significant difference in the multiple-choice test scores. After completing the module, there was no significant difference in skills test scores between interns and PGY-2 to PGY-5 residents. Both tests were validated using the scores obtained from PGY-2 to PGY-5 residents. Our combined didactic and simulation course significantly improved intern and

The aim of this study was to evaluate incidence of prior fussy emergency visits in infants with subsequently diagnosed fractures suggestive of abuse. This was a retrospective chart review of infants younger than 6 months who presented to the pediatric emergency department (ED) between January 1, 2006, and December 31, 2011. Inclusion criteria included age 0 to 6 months, discharge diagnosis including "fracture," "broken" (or break), or "trauma" or any child abuse diagnosis or chief complaint of "fussy" or "crying" as documented in the electronic medical record by the triage nurse. Three thousand seven hundred thirty-two charts were reviewed, and 279 infants with fractures were identified. Eighteen (6.5%) of 279 infants had a prior ED visit for fussiness without an obvious source. Of these, 2 had a witnessed event causing their fracture, and therefore the fracture was not considered concerning for abuse. The remaining 16 had fractures concerning for abuse. Mean age was 2.5 (SD, 1.2) months. Fifteen (83%) of 18 infants were 3 months or younger at the time of the fussy visit. The mean interval between the first and second ED visits was 27 days (median, 20 days). Thirty-nine percent were evaluated by a pediatric emergency medicine-trained physician during their initial fussy visit, whereas 78% were evaluated by pediatric emergency medicine-trained physician during their subsequent visit. Most common injuries were multiple types of fractures followed by extremity and rib fractures. Fractures concerning for child abuse are an important cause of unexplained fussiness in infants presenting to the pediatric ED. A high index of suspicion is essential for prompt diagnosis and likely prevention of other abuse.

Under the hypothesis that the elbow alignment, namely the carrying angle, could predispose individuals to a specific type of pediatric elbow fracture after a fall onto an outstretched arm, we investigated the relationship between radiographic carrying angle and elbow fracture type in children. Retrospective case-control study. Level I pediatric trauma center. We reviewed 374 children who were diagnosed with supracondylar fracture (SCF, n = 208), lateral condylar fracture (LCF, n = 132), and radial neck fracture (RNF, n = 34). The association between the radiographic carrying angle and the fracture type was investigated. To adjust for bias, 2 statistical methods were used: multivariate analysis using a baseline-category logistic model and a case-matching method using propensity score analysis. In the multivariate analysis, with SCF patients set as the baseline category, a more valgus-deviated elbow (increased carrying angle, P = 0.011) predisposed individuals to RNF, whereas a more varus-deviated elbow (decreased carrying angle, P predisposed them to LCF. In the case-matched analysis, there were also significant differences in carrying angles between RNF and case-matched SCF patients (14.3 vs. 11.4 degrees, P = 0.013) and between LCF and case-matched SCF patients (7.7 vs. 11.7 degrees, P fall onto an outstretched elbow, could be a predisposing factor for specific types of pediatric elbow fracture. The results provide the additional information about the injury mechanisms of pediatric elbow fracture and may deepen our understanding of the fractures. Prognostic Level III.

The development of Computed Tomography (CT) scanning has revolutionized the role of radiology in the management of the pediatric head trauma. The procedure is safe and can be repeated to reasses a changing neurologic picture, thereby correlation the clinical and pathologic changes. This study included evaluation of CT of 178 infants and children with head trauma during the period of 31 months from Feb. 1979 to Aug. 1981 in the Department of Radiology, College of Medicine, Hanyang University. 1. Age distribution of the total 178 pediatric patients was ranging from one month to 16 years. The pediatric patient population was comprised of 128 males and 50 females, and its male to female ratio was about 2.5 : 1. The incidence of age occurring in 3 to 6 years was 38.2% and 7 to 10 years was 29.2%. Therefore the distribution of age between 3 to 6 years and 7 to 10 years was occurred in two-thirds of all pediatric patients. 2. Of all cases of injuries, traffic accidents were 60.1% and falls were 34.8%. 3. Skull fracture were roentgenographically detected in 61 (34.3%). However, the incidence of fractures in pretoddler group (0-2 years) was 61.1% and 7 to 10 years was 37.8%, 3 to 6 years was 36.8%. More common site of skull fracture was occipital bone,next partietal bone. 4. 54.8% of pediatric head trauma due to a full had a skull fracture, as did 25.2 % of those who were injured in traffic accident. 5. Cerebral Computed Tomography (CT) of the total 178 pediatric patients were revealed as following study.: Normal was 74.2%, epidural hematoma was 8.9%, subdural hematoma was 5.1%, cerebral contusion was 4.5%, intracerebral hematoma was 2.2% etc. 6. Of 25 cases of the epidural and subdural hematoma, supratentorial area was 15 cases, infratentorial area was 10 cases. 7. Most of the epidural hematoma was demonstrated a clear mental state. 8. However, intracerebral hematoma and cerebral contusion were occurred almost impairment of mental state

Mandibular fractures are relatively less frequent in children when compared to adults, which may be due to the child's protected anatomic features and infrequent exposure of children to alcohol related traffic accidents. Treatment principles of mandibular fractures differ from that of adults due to concerns regarding mandibular growth and development of dentition. A case of a 4.5-year-old boy with fractured body of mandible managed by closed reduction using open occlusal acrylic splint and circum mandibular wiring is presented. This article also provides a review of literature regarding the management of mandibular body fracture in young children.

Screening pelvic radiographs to rule out pelvic fractures are routinely used for the initial evaluation of pediatric blunt trauma. Recently, the utility of routine pelvic radiographs in certain subsets of patients with blunt trauma has been questioned. There is a growing amount of evidence that shows the clinical exam is reliable enough to obviate the need for routine screening pelvic radiographs in children. To identify variables that help predict the presence or absence of pelvic fractures in pediatric blunt trauma. We conducted a retrospective study from January 2005 to January 2010 using the trauma registry at a level 1 pediatric trauma center. We analyzed all level 1 and level 2 trauma victims, evaluating history, exam and mechanism of injury for association with the presence or absence of a pelvic fracture. Of 553 level 1 and 2 trauma patients who presented during the study period, 504 were included in the study. Most of these children, 486/504 (96.4%), showed no evidence of a pelvic fracture while 18/504 (3.6%) had a pelvic fracture. No factors were found to be predictive of a pelvic fracture. However, we developed a pelvic fracture screening tool that accurately rules out the presence of a pelvic fracture P = 0.008, NPV 99, sensitivity 96, 8.98 (1.52-52.8). This screening tool combines eight high-risk clinical findings (pelvic tenderness, laceration, ecchymosis, abrasion, GCS blunt trauma can reliably be ruled out by using our pelvic trauma screening tool. Although no findings accurately identified the presence of a pelvic fracture, the screening tool accurately identified the absence of a fracture, suggesting that pelvic radiographs are not warranted in this subset of patients.

A high percentage of the pediatric imaging studies requested during calls are related to musculoskeletal disease. Since bones and joints in children are immature, constantly growing and remodeling, they have physiological and anatomical peculiarities that make it necessary to use an approach specific for pediatric patients. In this article, we use three clinical scenarios (limping, fractures, and musculoskeletal infections) to summarize and transmit the concepts that are essential in emergency musculoskeletal imaging in children.

A Method for Direct Fabrication of a Lingual Splint for Management of Pediatric Mandibular Fractures

Directory of Open Access Journals (Sweden)

Gerardo P. Romeo, DDS, MD

2013-10-01

Full Text Available Summary: Pediatric mandibular fractures have successfully been managed in various ways. The use of a lingual splint is one such option. The typical indirect method for acrylic lingual splint fabrication involves obtaining dental impressions. Dental models are produced from those impressions so that model surgery may be performed. The splint is then made on those models using resin powder and liquid monomer in a wet laboratory and transferred to the patient. Obvious limitations to this technique exist for both patient and operator. We present a technique for direct, intraoperative, fabrication of a splint using commercially available light-cured material that avoids some of the shortcomings of the indirect method. Recommendations are made based on available material safety information.

To summarize the clinical characteristics and outcomes of pediatric sports-related concussion (SRC) patients who were evaluated and managed at a multidisciplinary pediatric concussion program and examine the healthcare resources and personnel required to meet the needs of this patient population. We conducted a retrospective review of all pediatric SRC patients referred to the Pan Am Concussion Program from September 1st, 2013 to May 25th, 2015. Initial assessments and diagnoses were carried out by a single neurosurgeon. Return-to-Play decision-making was carried out by the multidisciplinary team. 604 patients, including 423 pediatric SRC patients were evaluated at the Pan Am Concussion Program during the study period. The mean age of study patients was 14.30 years (SD: 2.32, range 7-19 years); 252 (59.57%) were males. Hockey (182; 43.03%) and soccer (60; 14.18%) were the most commonly played sports at the time of injury. Overall, 294 (69.50%) of SRC patients met the clinical criteria for concussion recovery, while 75 (17.73%) were lost to follow-up, and 53 (12.53%) remained in active treatment at the end of the study period. The median duration of symptoms among the 261 acute SRC patients with complete follow-up was 23 days (IQR: 15, 36). Overall, 25.30% of pediatric SRC patients underwent at least one diagnostic imaging test and 32.62% received referral to another member of our multidisciplinary clinical team. Comprehensive care of pediatric SRC patients requires access to appropriate diagnostic resources and the multidisciplinary collaboration of experts with national and provincially-recognized training in TBI.

Distinguishing between accidental and abusive head trauma in children can be difficult, as there is a lack of baseline data for pediatric cranial fracture patterns. A porcine head model has recently been developed and utilized in a series of studies to investigate the effects of impact energy level, surface type, and constraint condition on cranial fracture patterns. In the current study, an automated pattern recognition method, or a fracture printing interface (FPI), was developed to classify cranial fracture patterns that were associated with different impact scenarios documented in previous experiments. The FPI accurately predicted the energy level when the impact surface type was rigid. Additionally, the FPI was exceedingly successful in determining fractures caused by skulls being dropped with a high-level energy (97% accuracy). The FPI, currently developed on the porcine data, may in the future be transformed to the task of cranial fracture pattern classification for human infant skulls. © 2016 American Academy of Forensic Sciences.

Maxillofacial trauma in children is not common worldwide. Domestic injuries are frequently seen in younger children while older children are mostly involved in motor vehicle accidents (MVA). The objective of this study was to analyze the pattern of maxillofacial injuries in pediatric patients referred to three government main hospitals in different areas of West Malaysia. Patients' records of three selected hospitals in Malaysia (National University of Malaysia Hospital, Kajang Hospital and Seremban Hospital) from January 1999 to December 2001 were reviewed. Data associated with demographics, etiology of injury in relation to age group, type of injuries whether soft tissues of hard tissue in relation to age group and treatment modalities were collected. A total of 521 pediatric patients' records were reviewed. Malays made up the majority of patients with maxillofacial injuries in the three hospitals. Males outnumbered females in all the three hospitals. Injuries commonly occur in the 11-16 years old. MVA was the most common etiology followed by fall and assault. Soft tissue injuries were the most common type of injuries in all the hospitals. In relation to fractures, mandible was the most common bone to fracture with condyle being the most common site. Orbital fracture was the most common fracture in the midfacial area. Most of the fractures were managed conservatively especially in the younger age groups. Open reduction with or without internal fixation was more frequently carried out in the 11-16 years old group. Children exhibit different pattern of clinical features depending on the etiology and stage of their bone maturation. A dedicated team, who is competent in trauma and aware of the unique anatomy, physical and psychological characteristics of children, should manage pediatric patient with trauma.

Human evolution and osteoporosis-related spinal fractures.

Directory of Open Access Journals (Sweden)

Meghan M Cotter

Full Text Available The field of evolutionary medicine examines the possibility that some diseases are the result of trade-offs made in human evolution. Spinal fractures are the most common osteoporosis-related fracture in humans, but are not observed in apes, even in cases of severe osteopenia. In humans, the development of osteoporosis is influenced by peak bone mass and strength in early adulthood as well as age-related bone loss. Here, we examine the structural differences in the vertebral bodies (the portion of the vertebra most commonly involved in osteoporosis-related fractures between humans and apes before age-related bone loss occurs. Vertebrae from young adult humans and chimpanzees, gorillas, orangutans, and gibbons (T8 vertebrae, n = 8-14 per species, male and female, humans: 20-40 years of age were examined to determine bone strength (using finite element models, bone morphology (external shape, and trabecular microarchitecture (micro-computed tomography. The vertebrae of young adult humans are not as strong as those from apes after accounting for body mass (p<0.01. Human vertebrae are larger in size (volume, cross-sectional area, height than in apes with a similar body mass. Young adult human vertebrae have significantly lower trabecular bone volume fraction (0.26±0.04 in humans and 0.37±0.07 in apes, mean ± SD, p<0.01 and thinner vertebral shells than apes (after accounting for body mass, p<0.01. Since human vertebrae are more porous and weaker than those in apes in young adulthood (after accounting for bone mass, even modest amounts of age-related bone loss may lead to vertebral fracture in humans, while in apes, larger amounts of bone loss would be required before a vertebral fracture becomes likely. We present arguments that differences in vertebral bone size and shape associated with reduced bone strength in humans is linked to evolutionary adaptations associated with bipedalism.

Too many pediatric trampoline injuries.

Recent reports note a dramatic increase in the number of pediatric trampoline injuries (PTI) during the past several years. In 1996, the US Consumer Product Safety Commission estimates that 83 000 patients received treatment for trampoline injuries in US hospital emergency departments (EDs), and that approximately 75% of these patients were trampolines accounted for 99% of PTI. Most injuries (66%) occurred on the trampoline, 28% resulted from falls off, and 4% from imaginative mechanisms. One hundred eleven patients (15%) suffered severe injury (1990 Abbreviated Injury Scale value >/=3), usually of an extremity (89 out of 111). Fractures occurred in 324 patients (45%). Spinal injuries were common (12%), including 7 patients with cervical or thoracic fractures, and 1 with C7 paraplegia. Fractures were more frequently associated with falls off the trampoline, whereas spinal injuries more frequently occurred on the trampoline. Eighty patients (11%) required prehospital medical transport to our ED, 584 (80%) had ED radiographs, and 382 (53%) required pediatric surgical subspecialty involvement. Seventeen percent of PTI patients (125 out of 727) were admitted to the hospital, including 9 to the pediatric intensive care unit; 99 (14%) required one or more operations. Mean hospital stay was 2 days (range, 1-63 days); 24 stays (19%) were for >/=3 days. We estimate that the hospital charges for the acute medical care of PTI study patients at our institution totaled approximately $700 000. PTI are dramatically increasing in number, and result in considerable childhood morbidity. Most PTI occur on privately owned trampolines. Few, if any, safety recommendations for the trampoline are followed. We support recommendations for a ban on the recreational, school, and competitive pediatric use of trampolines.

This systematic review of the Brazilian and worldwide literature aimed to evaluate the incidence and causes of perioperative and anesthesia-related mortality in pediatric patients. Studies were identified by searching EMBASE (1951-2011), PubMed (1966-2011), LILACS (1986-2011), and SciElo (1995-2011). Each paper was revised to identify the author(s), the data source, the time period, the number of patients, the time of death, and the perioperative and anesthesia-related mortality rates. Twenty trials were assessed. Studies from Brazil and developed countries worldwide documented similar total anesthesia-related mortality rates (anesthesia-related mortality rates in the past decade. Higher anesthesia-related mortality rates (2.4-3.3 per 10,000 anesthetics) were found in studies from developing countries over the same time period. Interestingly, pediatric perioperative mortality rates have increased over the past decade, and the rates are higher in Brazil (9.8 per 10,000 anesthetics) and other developing countries (10.7-15.9 per 10,000 anesthetics) compared with developed countries (0.41-6.8 per 10,000 anesthetics), with the exception of Australia (13.4 per 10,000 anesthetics). The major risk factors are being newborn or less than 1 year old, ASA III or worse physical status, and undergoing emergency surgery, general anesthesia, or cardiac surgery. The main causes of mortality were problems with airway management and cardiocirculatory events. Our systematic review of the literature shows that the pediatric anesthesia-related mortality rates in Brazil and in developed countries are similar, whereas the pediatric perioperative mortality rates are higher in Brazil compared with developed countries. Most cases of anesthesia-related mortality are associated with airway and cardiocirculatory events. The data regarding anesthesia-related and perioperative mortality rates may be useful in developing prevention strategies.

Skull fracture is one of the most common pediatric traumas. However, injury assessment tools for predicting pediatric skull fracture risk is not well established mainly due to the lack of cadaver tests. Weber conducted 50 pediatric cadaver drop tests for forensic research on child abuse in the mid-1980s (Experimental studies of skull fractures in infants, Z Rechtsmed. 92: 87-94, 1984; Biomechanical fragility of the infant skull, Z Rechtsmed. 94: 93-101, 1985). To our knowledge, these studies contained the largest sample size among pediatric cadaver tests in the literature. However, the lack of injury measurements limited their direct application in investigating pediatric skull fracture risks. In this study, 50 pediatric cadaver tests from Weber's studies were reconstructed using a parametric pediatric head finite element (FE) model which were morphed into subjects with ages, head sizes/shapes, and skull thickness values that reported in the tests. The skull fracture risk curves for infants from 0 to 9 months old were developed based on the model-predicted head injury measures through logistic regression analysis. It was found that the model-predicted stress responses in the skull (maximal von Mises stress, maximal shear stress, and maximal first principal stress) were better predictors than global kinematic-based injury measures (peak head acceleration and head injury criterion (HIC)) in predicting pediatric skull fracture. This study demonstrated the feasibility of using age- and size/shape-appropriate head FE models to predict pediatric head injuries. Such models can account for the morphological variations among the subjects, which cannot be considered by a single FE human model.

Atypical Chronic Ankle Instability in a Pediatric Population Secondary to Distal Fibula Avulsion Fracture Nonunion.

Science.gov (United States)

El Ashry, Saad R; El Gamal, Tarek A; Platt, Simon R

Chronic ankle instability is a disabling condition, often occurring as a result of traumatic ankle injury. A paucity of published data is available documenting chronic ankle instability in the pediatric population. Much of the data has been confined to the adult population. We present 2 cases of chronic ankle instability, 1 in a 12-year-old and 1 in a 9-year-old patient. Unlike the typical adult etiology, the cause of instability was a dysfunctional lateral ligamentous complex as a consequence of bony avulsion of the tip of the fibula. Both patients had sustained a twisting injury to the ankle. The fractures failed to unite. The nonunion resulted in dysfunction of the anterior talofibular ligament with consequent chronic ankle instability. At the initial clinical assessment, magnetic resonance imaging was requested for both patients. In patient 1 (12 years old), the fracture was fixed with 2 headless screws and was immobilized in a plaster cast for 6 weeks. In patient 2 (9 years old), because of the small size of the avulsed fragment, fixation was not possible. A modified Gould-Broström procedure was undertaken, facilitating repair of the avulsed fragment using anchor sutures. Copyright © 2016 American College of Foot and Ankle Surgeons.

To assess the effect of comorbidity on relative survival after hip fracture. Relative survival analysis was undertaken in 16 838 fall-related hip fracture hospitalisations in New South Wales, Australia. Comorbidity was measured on the basis of additional diagnosis codes on the same hospital separation as the hip fracture using the Charlson Comorbidity Index (CCI). Interval-specific relative survival and relative excess risk of death were calculated. Comorbidity was more frequently documented in men than women across the age groups. Survival decreased with increasing age and increasing comorbidity, but the relative impact of comorbidity was greater in the younger-old age group (65-74 years). The excess mortality in men was not accounted for by age or comorbidities. This study demonstrates an association between increasing comorbidity and death particularly in the first 3 months post hip fracture. It also highlights a relative excess risk of death in men after hip fracture after adjusting for age and comorbidity. © 2012 The Authors. Australasian Journal on Ageing © 2012 ACOTA.

Studies from Brazil and developed countries worldwide documented similar total anesthesia-related mortality rates (<1 death per 10,000 anesthetics and declines in anesthesia-related mortality rates in the past decade. Higher anesthesia-related mortality rates (2.4-3.3 per 10,000 anesthetics were found in studies from developing countries over the same time period. Interestingly, pediatric perioperative mortality rates have increased over the past decade, and the rates are higher in Brazil (9.8 per 10,000 anesthetics and other developing countries (10.7-15.9 per 10,000 anesthetics compared with developed countries (0.41-6.8 per 10,000 anesthetics, with the exception of Australia (13.4 per 10,000 anesthetics. The major risk factors are being newborn or less than 1 year old, ASA III or worse physical status, and undergoing emergency surgery, general anesthesia, or cardiac surgery. The main causes of mortality were problems with airway management and cardiocirculatory events. Our systematic review of the literature shows that the pediatric anesthesia-related mortality rates in Brazil and in developed countries are similar, whereas the pediatric perioperative mortality rates are higher in Brazil compared with developed countries. Most cases of anesthesiarelated mortality are associated with airway and cardiocirculatory events. The data regarding anesthesia-related and perioperative mortality rates may be useful in developing prevention

This article provides an overview of the characteristics of radiologic diagnosis of fractures in the pediatric age group. Following an introduction to skeletal development, radiographic imaging is presented. In addition, more advanced imaging modalities, such as ultrasound, CT and MRI, are discussed. It is illustrated how these methods advance the diagnostic process when projection radiography fails to provide a satisfactory diagnosis. A short description of the anatomical characteristics of the growing skeleton is used to explain the mechanisms causing the typical fractures. Finally, specific fractures are reviewed, with emphasis on the most frequent fractures, especially those involving the elbow. (orig.) [de

The purpose of this study was to describe the role of public exercise equipment in pediatric hand traumas as a preventable etiological factor. Pediatric patients with hand injuries referred from the emergency department were evaluated retrospectively. Age and gender of the patients, timing, etiology, mechanism of hand trauma, localization of the injury, diagnoses of the patients, and hospitalization rates were reviewed. Amongst the 310 pediatric patients evaluated, 31 patients (10%) experienced injury related to public exercise equipment. Within this group of patients, most were between 5 to 9 years of age, and all injuries were blunt and crush type. Lacerations and fractures were the main diagnoses. Complex injuries that required inpatient care were reported in 19.3% of the patients. Public exercise equipment-related injuries are increasingly prevalent in pediatric hand traumas. Preventive actions such as shielding the moving parts should be taken to reduce these rates.

Mandible fractures account for 36 to 70 percent of all facial fractures. Despite their high prevalence, the literature lacks a comprehensive review of demographics, fracture patterns, timing of management, antibiotic selection, and outcomes, particularly when evaluating pediatric versus adult patients. The authors aim to determine the complication and infection rates after surgical treatment of mandibular fractures and the bacterial isolates and antibiotic sensitivities from mandible infections after open reduction and internal fixation at their institution. Data were collected retrospectively for all mandible fractures treated at the authors' institution between 2003 and 2013. Patients were divided into pediatric (younger than 16 years) and adult (16 years or older) subgroups. Demographics, fracture location, fracture cause, comorbidities, antibiotic choice, and subsequent complications and infections were analyzed. Data were evaluated using appropriate statistical tests for each variable. Three hundred ninety-five patients were evaluated. Demographics and fracture cause were similar to those reported in current literature. Of the 56 pediatric patients, complications occurred in 5.6 percent. Time from injury to operative intervention did not affect outcome. The complication rate was 17.5 percent and the infection rate was 9.4 percent in the adult subgroup. Time from injury to operative intervention, sex, and edentulism were not significant predictors of complication or infection. Tobacco use, number of fractures, number of fractures fixated, and surgical approach were predictors of complication and infection. Perioperative ampicillin-sulbactam had a significantly lower risk of infection. Certain demographic and operative factors lead to significantly higher risks of complications after surgical management of mandibular fractures. Ampicillin-sulbactam provides effective antibiotic prophylaxis. Risk factor modification may improve outcomes. Risk, IV.

Bone fractures are common in alcoholics. To analyse which factors (ethanol consumption; liver function impairment; bone densitometry; hormone changes; nutritional status, and disrupted social links and altered eating habits) are related to bone fractures in 90 alcoholic men admitted to our hospitalization unit because of organic problems. Bone homoeostasis-related hormones were measured in patients and age- and sex-matched controls. Whole-body densitometry was performed by a Hologic QDR-2000 (Waltham, MA, USA) densitometer, recording bone mineral density (BMD) and fat and lean mass; nutritional status and liver function were assessed. The presence of prevalent fractures was assessed by anamnesis and chest X-ray film. Forty-nine patients presented at least one fracture. We failed to find differences between patients with and without fractures regarding BMD parameters. Differences regarding fat mass were absent, but lean mass was lower among patients with bone fracture. The presence of fracture was significantly associated with impaired subjective nutritional evaluation (χ² = 5.79, P = 0.016), lower vitamin D levels (Z = 2.98, P = 0.003) and irregular eating habits (χ² = 5.32, P = 0.02). Reduced lean mass and fat mass, and altered eating habits were more prevalent among patients with only rib fractures (n = 36) than in patients with multiple fractures and/or fractures affecting other bones (n = 13). These last were more closely related to decompensated liver disease. Serum vitamin D levels showed a significant relationship with handgrip strength (ρ = 0.26, P = 0.023) and lean mass at different parts of the body, but not with fat mass. By logistic regression analysis, only vitamin D and subjective nutritional evaluation were significantly, independently related with fractures. Prevalent fractures are common among heavy alcoholics. Their presence is related more closely to nutritional status, lean mass and vitamin D levels than to BMD. Lean mass is more reduced

Baseball and softball are leading causes of sports-related facial trauma in the United States. We review our institutional experience (Strong Memorial Hospital, Rochester, NY) with these injuries and discuss measures to reduce their incidence. We review our institutions experience with facial fractures sustained during the course of a softball or baseball game over a 12-year period. A total of 38 patients were identified and medical records analyzed for patient demographics, type of impact, and fracture location. The male-to-female ratio was 3.2:1; mean age was 24.2 years, with 17 (45%) of the injuries occurring in the pediatric population. The majority of the injuries were caused by direct impact with the ball (68%), while player-player collisions (18%) and impact from a swung bat (13%) were responsible for the remaining injuries. There were a total of 39 fractures; 18 fractures (46%) involved the midface (level 2), skull (level 1) fractures accounted for 12 (31%), while 9 (23%) were mandibular (level 3) fractures. With 68% of the injuries resulting from a ball impact, we endorse the recommendations of the Consumer Product Safety Commission for the use of low-impact National Operating Committee on Standards for Athletic Equipment-approved baseballs and softballs for youth and recreational leagues.

Pediatric health-related quality of life: a structural equation modeling approach.

Directory of Open Access Journals (Sweden)

Ester Villalonga-Olives

Full Text Available OBJECTIVES: One of the most referenced theoretical frameworks to measure Health Related Quality of Life (HRQoL is the Wilson and Cleary framework. With some adaptions this framework has been validated in the adult population, but has not been tested in pediatric populations. Our goal was to empirically investigate it in children. METHODS: The contributory factors to Health Related Quality of Life that we included were symptom status (presence of chronic disease or hospitalizations, functional status (developmental status, developmental aspects of the individual (social-emotional behavior, and characteristics of the social environment (socioeconomic status and area of education. Structural equation modeling was used to assess the measurement structure of the model in 214 German children (3-5 years old participating in a follow-up study that investigates pediatric health outcomes. RESULTS: Model fit was χ2 = 5.5; df = 6; p = 0.48; SRMR  = 0.01. The variance explained of Health Related Quality of Life was 15%. Health Related Quality of Life was affected by the area education (i.e. where kindergartens were located and development status. Developmental status was affected by the area of education, socioeconomic status and individual behavior. Symptoms did not affect the model. CONCLUSIONS: The goodness of fit and the overall variance explained were good. However, the results between children' and adults' tests differed and denote a conceptual gap between adult and children measures. Indeed, there is a lot of variety in pediatric Health Related Quality of Life measures, which represents a lack of a common definition of pediatric Health Related Quality of Life. We recommend that researchers invest time in the development of pediatric Health Related Quality of Life theory and theory based evaluations.

Use of dual energy X-ray absorptiometry in pediatric patients.

Wasserman, Halley; O'Donnell, Jennifer M; Gordon, Catherine M

2017-11-01

Dual Energy X-ray Absorptiometry (DXA) is a vital tool for assessing bone health in patients at risk for fragility fractures. In pediatric patients, this technology is used in conjunction with clinical fracture history to diagnosis osteoporosis and monitor treatment response. Childhood and adolescence is characterized by linear growth and bone mass accrual; thus there are important differences in the interpretation of bone measurements obtained by DXA in these young patients. This review aims to explore the current indications for DXA use and interpretation of DXA in the pediatric age group using currently available reference databases. Limitations of DXA in pediatric patients, specifically in children with short stature, will be explored. We will review several pathophysiologic mechanisms that may lead to low bone density in children, discussing representative diseases and the recommendations for monitoring bone health with DXA in these conditions. Finally, we will highlight new methods by which DXA imaging can gather additional information on bone health in children and may improve our ability to predict fractures and osteoporosis.

Full Text Available Incidence rate of symphysis mandible fracture in children was about 15 – 20%. Boys are effected twice as frequently as girls. The pattern of craniomaxillofacial fractures seen in children varies with evolving skeletal anatomy and socioenvironmental factors. The treatment of pediatric maxillofacial fractures is due to physiological, developmental, and anatomical characteristic of children. Management of pediatric mandible fracture by anatomic reduction is combine with stabilization adequate to maintain it until bone union has occured. This case report is aimed to explain about the management of simphysis mandible fracture in pediatric using erich arch bar. A 12 years old boy has fracture in mandible due to accident with mechanisme the chin hit the touching motorcyle tank. Clinically, was a deformity at the anterior of mandible and malocclusion has occured. Patient also complaint a  pain with swelling and bleeding at the regio of fracture and lip. Suturing was done  in wound area intra and extra oral, followed by application of arch bar in maxilla and mandible. Control at the third day was found a vague fracture line in panoramic radiograph. Management of emergency trauma in oral and maxillofacial surgery was based on principle of ATLS was done in this case. Following treatment was application of erich arch bar for mobility reducing the fracture of mandible symphisis. Management of mandibular symphisis fracture in 12 years old children with full eruption of teeth has been given a good healing  due to the teeth  was act to develop retention and stabilize the erich arch bar. Management of pediatric simphysis mandible fracture for 12 years old children with full eruption of teeth using erich bar revealed a healed fracture.

Although children with isolated skull fractures rarely require acute interventions, most are hospitalized. Our aim was to safely decrease the hospitalization rate for children with isolated skull fractures. We designed and executed this multifaceted quality improvement (QI) initiative between January 2008 and July 2015 to reduce hospitalization rates for children ≤21 years old with isolated skull fractures at a single tertiary care pediatric institution. We defined an isolated skull fracture as a skull fracture without intracranial injury. The QI intervention consisted of 2 steps: (1) development and implementation of an evidence-based guideline, and (2) dissemination of a provider survey designed to reinforce guideline awareness and adherence. Our primary outcome was hospitalization rate and our balancing measure was hospital readmission within 72 hours. We used standard statistical process control methodology to assess change over time. To assess for secular trends, we examined admission rates for children with an isolated skull fracture in the Pediatric Health Information System administrative database. We identified 321 children with an isolated skull fracture with a median age of 11 months (interquartile range 5-16 months). The baseline admission rate was 71% (179/249, 95% confidence interval, 66%-77%) and decreased to 46% (34/72, 95% confidence interval, 35%-60%) after implementation of our QI initiative. No child was readmitted after discharge. The admission rate in our secular trend control group remained unchanged at 78%. We safely reduced the hospitalization rate for children with isolated skull fractures without an increase in the readmissions. Copyright © 2016 by the American Academy of Pediatrics.

Full Text Available The objectives of the present study were to calculate the cost of illness of osteoporosis and to assess drug utilization patterns in postmenopausal women after a fracture-related hospitalization. The study subjects were enrolled from a large population-based administrative database. Female patients (age ≥ 65 years who were hospitalized for a typical osteoporotic fracture between 1/1/2000 and 31/12/2005 were included. Patients were classified as exposed/unexposed to treatment according to the presence/absence of at least one prescription for an osteoporosis-related medication in the 6 months following the discharge date. Treatment adherence was calculated for patients who were exposed to bisphosphonate therapy and was defined as at least 80% of treatment coverage during the follow-up period of 18 months after the discharge date. Hospitalizations, medications, diagnostic tests, laboratory tests and specialist visits during the 18-month follow-up period were collected and classified as osteoporosis-related or non-related to osteoporosis. A total of 12,376 patients were included in the study (mean age ± SD, 79.1 ± 7.5 years, out of which 97.9% (n = 12,110 were hospitalized due to an osteoporosis-related fracture and only 2.1% (n = 266 had general osteoporosis diagnosis. Among the 12,110 women with a fracture, 15.2% (n = 1,845 had a subsequent fracture-related hospitalization (63.8% of the patients had hip fracture. Only 32.3% (n = 4,001 of all included patients was exposed to osteoporosis-related medications and out of those patients exposed to bisphosphonates (n = 860 only 34.2% (n = 294 was adherent to therapy. The average cost per patient was € 4,481, of which € 1,089 was for osteoporosis-related and € 3,392 for non-osteoporosis-related items. The average cost of a matching cohort of patients without hospitalizations for fracture was € 2,339. Among osteoporosis-related costs, 87.0% was due to hospitalizations for subsequent fractures

There are limited data about trends in hip fracture-related mortality. In this study, we examined temporal trends in hip fracture mortality rates among persons aged 50 years or older in Texas between 1990 and 2007. Hip fracture-related mortality was defined as a death on the multiple cause of death record for which hip fracture was listed as a contributing cause. Population estimates for Texas were used as the denominator to calculate mortality rates per 100,000 persons. The joinpoint regression analysis was used to identify points where a statistically significant change occurred in the linear slope of the rates. A total of 14,350 death certificates listed hip fracture as a contributing cause of death. Hip fracture rates decreased predominantly among men by 0.8% (95% CI, -1.5 to -0.1) per year. Conversely, age-adjusted rates among women increased by 0.3% (95% CI, -0.4 to 1.0) per year. By race/ethnicity, hip fracture mortality rates increased annually 2.2% (95% CI, -0.1 to 4.4) among blacks, whereas the rates among whites and Hispanics remained steady. Moreover, the proportion of death records that listed nursing homes and residence as a place of death increased by 2.2% (95% CI, 1.6 to 2.9) and 8.7% (95% CI, 6.3 to 11.0) per year, respectively. Hip fracture mortality rates decreased predominantly among men in Texas during the study period. Increasing hip fracture mortality rates among blacks and nursing home residents merit further research.

Among older people, fracture-causing fall often leads to health deterioration. The role of endogenous hormone status and muscle strength on fall-related fracture risk is unclear. This study investigates if, after adjustment for bone density, endogenous hormones and muscle strength would predict fall-related limb fracture incidence in older community-dwelling women followed-up over 10 years. As a part of a prospective population-based study, 187 75-year-old women were investigated. Serum estradiol, testosterone, sex hormone binding globulin, and dehydroepiandrosterone sulfate concentrations were analyzed, and isometric muscle strength and bone mineral density were assessed. Fall-related limb fractures were gathered from patient records. Serum estradiol concentration was a significant predictor of fall-related limb fractures. Women with serum estradiol concentrations less than 0.022 nmol/L had a 3-fold risk (relative risk 3.05; 95% confidence interval, 1.26-7.36), and women with estradiol concentrations between 0.022 and 0.066 nmol/L doubled the risk (relative risk 2.24; 95% confidence interval, 0.97-5.19) of fall-related limb fracture compared to the women with estradiol concentrations ()above 0.066 nmol/L. Adjustment for muscle strength and bone mineral density did not materially change the risk estimates. High muscle strength was associated with a low incidence of fall-related limb fractures. This study showed that in 75-year-old women higher serum estradiol concentration and greater muscle strength were independently associated with a low incidence of fall-related limb fractures even after adjustment for bone density. Our results suggest that hormonal status and muscle strength have their own separate mechanisms protecting from fall-related fractures. This finding is of importance in developing preventive strategies, but calls for further study.

Although fractures in both the pediatric and, especially, the elderly populations have been extensively investigated, comparatively little attention has been given to the age group in between. Thus, we used the comprehensive (inpatient and outpatient) data resources of the Rochester Epidemiology Project to determine incidence rates for all fractures among young adult (age range, 18 to 49 years) residents of Olmsted County, Minnesota, in 2009 to 2011, and compared the distribution of fracture sites and causes in this young adult cohort with those for older residents aged 50 years or older. During the 3-year study period, 2482 Olmsted County residents aged 18 to 49 years experienced 1 or more fractures. There were 1730 fractures among 1447 men compared with 1164 among 1035 women, and the age-adjusted incidence of all fractures was 66% greater among the men (1882 [95% confidence interval 1793-1971] versus 1135 [95% CI 1069-1201] per 100,000 person-years; p age ≥50 years who sustained a fracture in 2009 to 2011. Younger residents (aged 18 to 49 years), when compared with older residents (aged ≥50 years), had a greater proportion of fractures of the hands and feet (40% versus 18%) with relatively few fractures observed at traditional osteoporotic fracture sites (14% versus 43%). Vertebral fractures were still more likely to be the result of moderate trauma than at other sites, especially in younger women. In conclusion, whereas pediatric and elderly populations often fracture from no more than moderate trauma, young adults, and more commonly men, suffer fractures primarily at non-osteoporotic sites due to more significant trauma. © 2017 American Society for Bone and Mineral Research. © 2017 American Society for Bone and Mineral Research.

Radiological diagnosis of fractures

This book is about radiology of fractures. While it contains sections of clinical features it is not intended that readers should rely entirely upon these for the diagnosis and management of the injured patient. As in the diagnosis and treatment of all medical problems, fracture management must be carried out in a logical step-by-step fashion - namely, history, examination, investigation, differential diagnosis, diagnosis and then treatment. Each section deals with a specific anatomical area and begins with line drawings of the normal radiographs demonstrating the anatomy. Accessory views that may be requested, and the indications for these, are included. Any radiological pitfalls for the area in general are then described. The fractures in adults are then examined in turn, their radiological features described, and any pitfalls in their diagnosis discussed. A brief note of important clinical findings is included. A brief mention is made of pediatric fractures which are of significance and their differences to the adult pattern indicated. Although fractures can be classified into types with different characteristics, in life every fracture is individual. Fractures by and large follow common patterns, but many have variations

Nowadays pediatric femoral fractures are more commonly managed with operative treatment rather than conservative treatment because of more rapid recovery and avoidance of prolonged immobilization. Children between the ages of 5-13 years are treated either by traction plus hip spica and flexible/elastic stable retrograde intramedullary nail, or external fixators in the case of open fractures. The aim of this study is to evaluate the outcome of pediatric femoral shaft fractures treated by stainless steel flexible intramedullary nail in children between 5 and 13 years of age. There were 32 cases of femoral shaft fractures which were all fixed with stainless steel flexible intramedullary nail under fluoroscopy. Long leg cast was applied at the time of fixation. Partial weight bearing was started 2 weeks after surgery. Patients were evaluated in follow-up study to observe the alignment of fracture, infection, delayed union, nonunion, limb length discrepancy, motion of knee joint, and time to unite the fracture. We were able to follow up 28 out of 32 patients. The patients were 8.14 years of age on average. The mean hospital stay after operation was 4 days and fracture union time was 9.57 weeks. There were 3 cases of varus angulation, 2 cases of anterior angulation, and 4 cases of limb lengthening. Patients aged between 5 and 13 years treated with flexible intramedullary nail for closed femoral shaft fracture have rapid union and recovery, short rehabilitation period, less immobilization and psychological impact, and cost-effective.

Miniplate for osteosynthesis in a 9-year-old with symphysis fracture: clinical report.

Science.gov (United States)

Osteosynthesis using minimum material in pediatric mandibular fractures is the key, due to the limited space available in the mandible, especially in the mental foramen and apical region. There is an important role of open reduction and rigid internal fixation in re-establishing facial height, width and projection. During the early years of growth and development, there is a high osteogenic potential of the bones. The thick periosteum allows for rapid consolidation and remodeling at the site of fracture. Primary teeth have short, bulbous crowns which compromise stable maxillomandibular fixation during fracture reduction and stabilization using traditional methods. Further, stability of the fractured segments may be hampered because of the displaced or mobile permanent anterior teeth in the mixed dentition along the line of fracture. This clinical report outlines the use of miniplate with monocortical screws in a 9-year-old boy with symphysis fracture. How to cite this article: Srinivasan I, Kumar N, Jaganathan U, Bhandari A.

2016-05-01

The burden of obesity-related asthma among children, particularly among ethnic minorities, necessitates an improved understanding of the underlying disease mechanisms. Although obesity is an independent risk factor for asthma, not all obese children develop asthma. Several recent studies have elucidated mechanisms, including the role of diet, sedentary lifestyle, mechanical fat load, and adiposity-mediated inflammation that may underlie the obese asthma pathophysiology. Here, we review these recent studies and emerging scientific evidence that suggest metabolic dysregulation may play a role in pediatric obesity-related asthma. We also review the genetic and epigenetic factors that may underlie susceptibility to metabolic dysregulation and associated pulmonary morbidity among children. Lastly, we identify knowledge gaps that need further exploration to better define pathways that will allow development of primary preventive strategies for obesity-related asthma in children.

Managing staff stress and preventing long-term burnout in oncology staff are highly important for both staff and patient well-being. Research addressing work-related stress in adult oncology is well documented; however, less is known about this topic in the pediatric context. This study examined sources of work-related stress and reward specific to multidisciplinary staff working in pediatric oncology in Australia. Participants were 107 pediatric oncology clinicians, including medical, nursing, and allied health staff from two Australian pediatric oncology centers. Participants completed an online survey using two newly developed measures: the work stressors scale-pediatric oncology and the work rewards scale-pediatric oncology. The most commonly reported sources of both stress and reward are related to patient care and interactions with children. Results indicated that levels of work-related stress and reward were similar between the professional disciplines and between the two hospitals. Regression analyses revealed no demographic or organizational factors that were associated with either stress or reward. Work-related stress and reward are not mutually exclusive; particular situations and events can be simultaneously stressful and rewarding for healthcare providers. Although patient care and interactions with children was found to be the most stressful aspect of working in this speciality, it was also the greatest source of reward. Results are discussed in relation to workplace approaches to staff well-being and stress reduction. Copyright © 2015 John Wiley & Sons, Ltd.

The purpose was to evaluate the incidence, etiology, site and patterns, management and treatment methods, and outcome of pediatric patients with mandibular fractures. Pediatric patients (1.5-16 years old) with mandibular fractures, treated at the Soroka University Medical Center were included in the study. Age, gender, etiology, site and type of fracture, associated injuries, mode of treatment, outcome, complications, and follow up were evaluated. The cases were divided into 3 age groups: Group A: 1.5-5 years, Group B: 6-11 years, and Group C: 12-16 years. Sixty one patients were included in the study. The male to female ratio was 2:1. Motor vehicle accident was the most common cause. Associated trauma was more common in young children. The condyle was involved in 54% of the fractures. Closed reduction and intermaxillary fixation was the most common treatment used. Complications were rare. Management of mandibular fracture in the pediatric age group is a challenge. The anatomical complexity of the developing mandible and teeth strongly suggest the use of surgical techniques that are different from those routinely used in adults. The conservative approach is recommended. Whenever possible closed reduction should be the treatment of choice. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Skull and Posterior Rib Fractures with Respiratory Failure caused by Child Abuse

Directory of Open Access Journals (Sweden)

Dzulfikar Djalil Lukmanul Hakim

2017-03-01

Full Text Available Background: Presence of multiple fractures suggests child abuse. Skull fractures rarely occurred but posterior rib fractures are commonly found and have high specificity as a radiological finding in child abuse. A respiratory failure can occur as a result of the damage to the osseous structure of the thorax that destabilizes the rib cage and impairs spontaneous breathing mechanism. Methods: A case report of a 6-month-old boy who presented with respiratory failure, multiple bilateral parietal and occipital bone fractures, and also fractures of right rib 5–8. The patient required ventilatory support for 9 days in the Pediatric Intensive Care Unit, Dr.HasanSadikin General Hospital. Results: The patient was on ventilatory support for 9 days, and was given antibiotics for 2 weeks. Next, the patient was referred to the High Care Unit (HCU after the condition was stabilized, and then referred to the ward, for treatment by the Social Pediatric Division. The patient was still having issues about his foster care. Conclusions: Recognition of presence of fractures is important in early diagnosis and treatment of child abuse.

Dexmedetomidine-related polyuria in a pediatric patient.

Adams, Phillip S; Cassara, Antonio

2016-04-01

Polyuria related to pharmacologic α2-adrenoreceptor agonism has been well described in vitro and in animal models and is thought to be the result of functional antagonism of arginine vasopressin. Despite its widespread use as a sedative and anesthetic adjunct, very few reports of dexmedetomidine-related polyuria in humans exist in the literature. We present the first description of a pediatric patient manifesting polyuria and hypernatremia in association with dexmedetomidine infusion for posterior spinal fusion.

Rib fractures are considered a marker of exposure to significant traumatic energy. In children, because of high elasticity of the chest wall, higher energy levels are necessary for ribs to fracture. The purpose of this study was to analyze patterns of associated injuries in children as compared with adults, all of whom presented with rib fractures. A retrospective cohort study involving blunt trauma patients with rib fractures registered in the National Trauma Registry was conducted. Of 6,995 trauma victims who were found to suffer from rib fractures, 328 were children and 6,627 were adults. Isolated rib fractures without associated injuries occurred in 19 children (5.8%) and 731 adults (11%). More adults had 4 or more fractured ribs compared with children (P pneumothorax (P = .006), spleen, and liver injury (P < .001). Mortality rate was 5% in both groups. The incidence of associated head, thoracic, and abdominal solid organ injuries in children was significantly higher than in adults suffering from rib fractures. In spite of a higher Injury Severity Score and incidence of associated injuries, mortality rate was similar. Mortality of rib fracture patients was mostly affected by the presence of extrathoracic injuries. Copyright © 2014 Elsevier Inc. All rights reserved.

The aim of this study was to assess the safety and efficiency of biodegradable self-reinforced (SR-PLDLA) bone plates and screws in open reduction and internal fixation of mandible fractures in children. Thirteen patients (5 female, 8 male; mean age 12 years, range 5-16 years) were operated on various fractures of the mandible (2 symphyseal, 6 parasymphyseal, 4 body, 3 angle, 1 ramus, 2 condylar fractures). The mean follow-up time was 26.4 months (range 10.9-43.4 months). Intermaxillary fixation was applied in cases with concomitant condylar fractures up to 3 weeks. Primary healing of the fractured mandible was observed in all patients. Postoperative complications were minor and transient. The outcome of the operations was not endangered. Adverse tissue reactions to the implants, malocclusion, and growth restrictions did not occur during the observation period. Pediatric patients benefit from the advantages of resorbable materials, especially from faster mobilization and the avoidance of secondary removal operations. Based on these preliminary results, self-reinforced fixation devices are safe and efficient in the treatment of pediatric mandible fractures. However, further clinical investigations are necessary to evaluate the long-term reliability.

2013-01-01

In Victoria, Australia, the age-standardised incidence of fall-related hip fracture hospitalisations decreased significantly by 25% over the period 1998/1999-2008/2009. Significant decreases in fall-related hip fractures were observed in males and females, across all 5-year age groups, in Australian-born and overseas-born Victorians, in all socio-economic quintiles and in community-dwelling older people. The study aim was to investigate trends in the incidence of fall-related and hip fracture hospitalisations among Victorians aged 65 years and older overall and by age, gender, country of birth, socio-economic status (SES) and location of the event (home, residential care institution, etc.) over the 11-year period 1998/1999 to 2008/2009. Annual counts and age-standardised rates for fall-related hospitalisations among people aged 65 years and older were estimated using Victorian hospital admissions data. The statistical significance of changes in trends over time were analysed using a log-linear regression model of the rate data assuming a Poisson distribution of cases. Although the age-standardised incidence of fall-related hospitalisations increased significantly by 13% (95% confidence interval [CI], 9% to 18%) in Victoria, the age-standardised incidence of fall-related hip fracture hospitalisations decreased from 600/100,000 in 1998/1999 to 467/100,000 in 2008/2009 - an estimated overall reduction of 25% (95% CI, -29% to -22%). By contrast, the age-standardised incidence of fall-related hospitalisations for fractures at other body sites either increased significantly or showed no significant change. Significant decreases in fall-related hip fractures were observed in both males and females, across all 5-year age groups, in both Australian-born and overseas-born Victorians, in all socio-economic quintiles and in community-dwelling older people but not in people living in residential care facilities. Despite the downward trend in the age-standardised incidence of

Few studies have assessed the effectiveness of different drugs for osteoporosis (OP). We aimed to determine if fracture and mortality rates vary among patients initiating different OP medications. We used the Medicare 5% sample to identify new users of intravenous (IV) zoledronic acid (n=1.674), oral bisphosphonates (n=32.626), IV ibandronate (n=492), calcitonin (n=2.606), raloxifene (n=1.950), or parathyroid hormone (n=549). We included beneficiaries who were ≥65 years of age, were continuously enrolled in fee-for-service Medicare and initiated therapy during 2007-2009. Outcomes were hip fracture, clinical vertebral fracture, and all-cause mortality, identified using inpatient and physician diagnosis codes for fracture, procedure codes for fracture repair, and vital status information. Cox regression models compared users of each medication to users of IV zoledronic acid, adjusting for multiple confounders. During follow-up (median, 0.8-1.5 years depending on the drug), 787 subjects had hip fractures, 986 had clinical vertebral fractures, and 2.999 died. Positive associations included IV ibandronate with hip fracture (adjusted hazard ratio (HR), 2.37; 95% confidence interval (CI) 1.25-4.51), calcitonin with vertebral fracture (HR=1.59, 95%CI 1.04-2.43), and calcitonin with mortality (HR=1.31; 95%CI 1.02-1.68). Adjusted HRs for other drug-outcome comparisons were not statistically significant. IV ibandronate and calcitonin were associated with higher rates of some types of fracture when compared to IV zolendronic acid. The relatively high mortality associated with use of calcitonin may reflect the poorer health of users of this agent.

Imaging of vertebral fracture in osteoporosis

Vertebral collapses are the most frequent fractures in osteoporosis. They are often overlooked, although their presence is a strong risk factor for development of new fractures. Lateral radiographs of the spine are the accepted standard for assessment of fractures. Qualitative (visual), semiquantitative and quantitative (morphometric) techniques are useful in determining the compressive deformities of vertebral bodies. In the present paper, the advantages and the disadvantages of these methods are discussed. The improvement of scan quality allows to use DXA technique to diagnose the fractures, in both - the visual and the morphometric way. The vertebral morphologic assessment also seems to be an important diagnostic tool in pediatric osteoporosis. Application of multidetector CT and especially MR in vertebral imaging of osteoporosis, improves the sensitivity of fracture detection and enables the differentiation of benign from malignant vertebral body collapses.

The quality of life during the first 4 months after fracture was estimated in 2,808 fractured patients from 11 countries. Analysis showed that there were significant differences in the quality of life (QoL) loss between countries. Other factors such as QoL prior fracture and hospitalisation also had a significant impact on the QoL loss. The International Costs and Utilities Related to Osteoporotic Fractures Study (ICUROS) was initiated in 2007 with the objective of estimating costs and quality of life related to fractures in several countries worldwide. The ICUROS is ongoing and enrols patients in 11 countries (Australia, Austria, Estonia, France, Italy, Lithuania, Mexico, Russia, Spain, UK and the USA). The objective of this paper is to outline the study design of ICUROS and present results regarding the QoL (measured using the EQ-5D) during the first 4 months after fracture based on the patients that have been thus far enrolled ICUROS. ICUROS uses a prospective study design where data (costs and quality of life) are collected in four phases over 18 months after fracture. All countries use the same core case report forms. Quality of life was collected using the EQ-5D instrument and a time trade-off questionnaire. The total sample for the analysis was 2,808 patients (1,273 hip, 987 distal forearm and 548 vertebral fracture). For all fracture types and countries, the QoL was reduced significantly after fracture compared to pre-fracture QoL. A regression analysis showed that there were significant differences in the QoL loss between countries. Also, a higher level of QoL prior to the fracture significantly increased the QoL loss and patients who were hospitalised for their fracture also had a significantly higher loss compared to those who were not. The findings in this study indicate that there appear to be important variations in the QoL decrements related to fracture between countries.

Scaphoid fractures in children

Directory of Open Access Journals (Sweden)

Gajdobranski Đorđe

2014-01-01

Full Text Available Introduction. Scaphoid fractures are rare in childhood. Diagnosis is very difficult to establish because carpal bones are not fully ossified. In suspected cases comparative or delayed radiography is used, as well as computerized tomography, magnetic resonance imaging, ultrasound and bone scintigraphy. Majority of scaphoid fractures are treated conservatively with good results. In case of delayed fracture healing various types of treatment are available. Objective. To determine the mechanism of injury, clinical healing process, types and outcome of treatment of scaphoid fractures in children. Methods. We retrospectively analyzed patients with traumatic closed fracture of the scaphoid bone over a ten-year period (2002-2011. The outcome of the treatment of “acute” scaphoid fracture was evaluated using the Mayo Wrist Score. Results. There were in total 34 patients, of mean age 13.8 years, with traumatic closed fracture of the scaphoid bone, whose bone growth was not finished yet. Most common injury mechanism was fall on outstretched arm - 76% of patients. During the examined period 31 children with “acute” fracture underwent conservative treatment, with average immobilization period of 51 days. Six patients were lost to follow-up. In the remaining 25 patients, after completed rehabilitation, functional results determined by the Mayo Wrist Score were excellent. Conclusion. Conservative therapy of “acute” scaphoid fractures is an acceptable treatment option for pediatric patients with excellent functional results.

The purpose of this study was to compare the rate of complications between buried and exposed intramedullary implants after fixation of pediatric forearm fractures. A retrospective comparative cohort study of 339 children treated with intramedullary fixation for displaced forearm fractures between 2004 and 2009 was performed. Implants were left exposed in 128 patients (37.8%) and buried beneath the skin in 208 patients (61.4%); 3 patients had buried and exposed hardware (0.9%). Data on demographics, injury, surgical technique, and complications were analyzed. The buried implant group was older (mean 10.3 vs. 8.5 y; P exposed implant group. The buried group had their implants removed later than the exposed group (median 3.5 vs. 1.2 mo; P exposed implants were successfully removed in the office. Complications were seen in 56 patients (16.5%). There were 16 patients (4.7%) with refracture and 12 patients (3.5%) with infection. The buried and exposed implant groups did not differ significantly with respect to refracture (3.1% vs. 7.0%; P = 0.20), infection (3.5% vs. 2.3%; P = 0.66), or overall complications (14.5% vs. 17.2%; P = 0.87). There was also no difference between groups with respect to loss of reduction, nondelayed or delayed union, loss of motion, hypertrophic granuloma, or tendon rupture. Buried implants were also associated with penetration through the skin (3.9%). Injury to the dominant arm and need for open reduction were significant predictors of complication (OR = 1.01; 95% CI, 1.001-1.012; P = 0.02 and OR = 0.51; 95% CI, 0.264-0.974; P = 0.04, respectively). There were no significant differences seen in number of infections, refractures, or overall complications based on whether implants were left exposed or buried beneath the skin after surgery. Level III, therapeutic.

Although much of the lay media attention surrounding sport-related concussion (SRC) focuses on professional athletes, SRC is a common injury in pediatric sports. The anatomy, biomechanics, and response to injury of the developing pediatric brain differ from those of the adult. Similarly, the neurocognitive abilities of the child are developing more rapidly than in an adult. The effects of concussive brain injury on the life of a child are different from those of an adult. This article focuses on the aspects of SRC that are specific to the younger athletes. Copyright © 2011 Elsevier Inc. All rights reserved.

The aim of this study was to identify the different influencing patterns of demographic and epilepsy-related variables on various aspects of psychosocial function in pediatric epilepsy. Five hundred ninety-eight patients with pediatric epilepsy between the ages of 4 and 18 years (boys=360, 60% and girls=238, 40%) and their parents participated in the study. Parents completed the Social Maturity Scale (SMS), the Korean version of the Child Behavior Checklist (K-CBCL), and the Korean version of the Quality of Life in Childhood Epilepsy Questionnaire (K-QOLCE) to assess daily living function, behavior, and quality of life. The Children's Global Assessment Scale (CGAS) was completed by clinicians to assess general adaptive function. Demographic variables, such as age and sex of child, and epilepsy-related clinical variables, including seizure type, seizure frequency, duration of epilepsy, and number of medications, were obtained from medical records. Demographic and epilepsy-related clinical variables had a strong influence (22-32%) on the cognition-related domain such as general adaptive function, school/total competence, and quality of life for cognitive function while a comparatively smaller effect (2-16%) on the more psychological domain including behavioral, emotional, and social variables. Younger age, shorter duration of illness, and smaller number of medications showed a strong positive impact on psychosocial function in pediatric epilepsy, particularly for adaptive function, competence, and quality-of-life aspects. Given the wide range of impact of demographic and clinical variables on various facets of psychosocial functions, more specific understanding of the various aspects of factors and their particular pattern of influence may enable more effective therapeutic approaches that address both the medical and psychological needs in pediatric epilepsy.

Rib fractures are considered highly suspicious for nonaccidental injury in the pediatric clinical literature; however, a rib fracture classification system has not been developed. As an aid and impetus for rib fracture research, we developed a concise schema for classifying rib fracture types and fracture location that is applicable to infants. The system defined four fracture types (sternal end, buckle, transverse, and oblique) and four regions of the rib (posterior, posterolateral, anterolateral, and anterior). It was applied to all rib fractures observed during 85 consecutive infant autopsies. Rib fractures were found in 24 (28%) of the cases. A total of 158 rib fractures were identified. The proposed schema was adequate to classify 153 (97%) of the observed fractures. The results indicate that the classification system is sufficiently robust to classify rib fractures typically observed in infants and should be used by researchers investigating infant rib fractures. © 2013 American Academy of Forensic Sciences.

Pediatric anesthesia-related cardiac arrest (ARCA) is an uncommon but potentially preventable adverse event. Infants and children with more severe underlying disease are at highest risk. We aimed to identify system- and anesthesiologist-related risk factors for ARCA. We analyzed a prospectively collected patient cohort data set of anesthetics administered from 2000 to 2011 to children at a large tertiary pediatric hospital. Pre-procedure systemic disease level was characterized by ASA physical status (ASA-PS). Two reviewers independently reviewed cardiac arrests and categorized their anesthesia relatedness. Factors associated with ARCA in the univariate analyses were identified for reevaluation after adjustment for patient age and ASA-PS. Cardiac arrest occurred in 142 of 276,209 anesthetics (incidence 5.1/10,000 anesthetics); 72 (2.6/10,000 anesthetics) were classified as anesthesia-related. In the univariate analyses, risk of ARCA was much higher in cardiac patients and for anesthesiologists with lower annual caseload and/or fewer annual days delivering anesthetics (all P risk adjustment for ASA-PS ≥ III and age ≤ 6 months, however, the association with lower annual days delivering anesthetics remained (P = 0.03), but the other factors were no longer significant. Case-mix explained most associations between higher risk of pediatric ARCA and anesthesiologist-related variables at our institution, but the association with fewer annual days delivering anesthetics remained. Our findings highlight the need for rigorous adjustment for patient risk factors in anesthesia patient safety studies.

2012-05-01

Full Text Available Abstract Background Population-based administrative data have been used to study osteoporosis-related fracture risk factors and outcomes, but there has been limited research about the validity of these data for ascertaining fracture cases. The objectives of this study were to: (a compare fracture incidence estimates from administrative data with estimates from population-based clinically-validated data, and (b test for differences in incidence estimates from multiple administrative data case definitions. Methods Thirty-five case definitions for incident fractures of the hip, wrist, humerus, and clinical vertebrae were constructed using diagnosis codes in hospital data and diagnosis and service codes in physician billing data from Manitoba, Canada. Clinically-validated fractures were identified from the Canadian Multicentre Osteoporosis Study (CaMos. Generalized linear models were used to test for differences in incidence estimates. Results For hip fracture, sex-specific differences were observed in the magnitude of under- and over-ascertainment of administrative data case definitions when compared with CaMos data. The length of the fracture-free period to ascertain incident cases had a variable effect on over-ascertainment across fracture sites, as did the use of imaging, fixation, or repair service codes. Case definitions based on hospital data resulted in under-ascertainment of incident clinical vertebral fractures. There were no significant differences in trend estimates for wrist, humerus, and clinical vertebral case definitions. Conclusions The validity of administrative data for estimating fracture incidence depends on the site and features of the case definition.

Much research exists demonstrating that pediatricians should counsel patients and families about tobacco. However, few data are available about tobacco-related messages relayed in pediatric offices. Since an anti-tobacco office environment can be a strong component of an active tobacco prevention program, we evaluated pediatric offices in Delaware to characterize tobacco-related messages. A convenience sample of 32 of 63 (51%) pediatric offices in Delaware was directly evaluated for the presence of tobacco-related messages. Fifty-five of 63 (87%) pediatric practices in Delaware were contacted by telephone to inquire about the presence of a tobacco coordinator. The 32 practices represented 71 physicians, were located in all three counties throughout the state, and were urban and non-urban in setting. The same investigator evaluated practices in a single site visit. All were located in smoke-free buildings. At one office, people were seen smoking outside; however, the presence of discarded cigarettes was much more common. Thirteen practices (41%) employed smokers, most of whom smoked outside during work hours. Twenty-one of 28 practices (75%) had waiting room magazines containing tobacco advertisements. Fifteen practices (47%) offered anti-tobacco literature while six practices (19%) displayed visual media, none exclusively addressing tobacco. Nine practices (28%) use chart flags to identify smokers. None of 55 pediatric practices in Delaware contacted by telephone identified an office tobacco prevention coordinator. Our data indicate that, in Delaware, the pediatric offices we visited overall convey a limited message about tobacco and could strengthen tobacco prevention strategies. Research measuring the impact of office-based anti-tobacco messages is needed. If these messages are effective in preventing tobacco use, practitioners can supplement active counseling with indirect interventions that require minimal maintenance once established and that place no

Rickets or abuse? A histologic comparison of rickets and child abuse-related fractures.

2015-03-01

The bone changes of vitamin D deficiency rickets have been invoked as an alternate explanation for child-abuse related fractures identified through medical imaging. The lack of modern histopathologic comparisons between these two entities limits the abilities of the forensic pathologist to address this differential diagnosis, both in their autopsy reports and on the witness stand. We report a comparison of the histologic appearance of the bones in a two year old child with vitamin D deficiency rickets with fractures occurring in three young children with child abuse. In the case of rickets, there was marked architectural disorganization of endochondral ossification at the costochondral junctions and growth plates of long bones. The child abuse-related fractures showed osteochondral callus at different stages of healing, either centered on a discrete fracture line or at metaphyses (e.g. classical metaphyseal lesions). In many instances, the healing fractures disrupted the line of endochondral ossification. In none of the child abuse-related fractures was there any similarity to the histologic appearance of rickets. The maturation disturbance in the growth plate that occurs in rickets is a distinctive entity that cannot be confused histologically with healing fractures, including the classical metaphyseal lesion.

Management of pediatric mandibular fracture using orthodontic vacuum-formed thermoplastic splint: A case report and review of literature.

2017-05-01

Fractures of the mandible are relatively less frequent in children when compared to adults. The anatomic features of children are protected. Children have a higher adaptation to maxillofacial fractures compared to adults. Treatment principles of mandibular fractures in children differ from that of adults due to concerns regarding mandibular growth and the developing dentition. A case of a 6-year-old boy with fractured mandibular symphysis managed by closed reduction using a vacuum formed thermoplastic splint and circummandibular wiring is presented. This article also provides a review of the literature regarding the management of mandibular fracture in young children.

The present study sought to investigate four of these indices (gap index, padding index, Canterbury index, and three-point index) as compared to a reference standard (cast index) for evaluation of plaster cast quality after closed reduction of pediatric displaced distal forearm fractures. Forty-three radiographs from patients with displaced distal forearm fractures requiring manipulation were reviewed. Accuracy, sensitivity, specificity, false-positive probability, false-negative probability, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were calculated for each of the tested indices. Comparison among indices revealed diagnostic agreement in only 4.7% of cases. The strongest correlation with the cast index was found for the gap index, with a Spearman correlation coefficient of 0.94. The gap index also displayed the best agreement with the cast index, with both indices yielding the same result in 79.1% of assessments. When seeking to assess plaster cast quality, the cast index and gap index should be calculated; if both indices agree, a decision on quality can be made. If the cast and gap indices disagree, the padding index can be calculated as a tiebreaker, and the decision based on the most frequent of the three results. Calculation of the three-point index and Canterbury index appears unnecessary. Copyright © 2016 Elsevier Ltd. All rights reserved.

Flow visualization and relative permeability measurements in rough-walled fractures

Persoff, P.; Pruess, K.

Two-phase (gas-liquid) flow experiments were done in a natural rock fracture and transparent replicas of natural fractures. Liquid was injected at constant volume flow rate, and gas was injected at either constant mass flow rate or constant pressure. When gas was injected at constant mass flow rate, the gas inlet pressure, and inlet and outlet capillary pressures, generally did not reach steady state but cycled irregularly. Flow visualization showed that this cycling was due to repeated blocking and unblocking of gas flow paths by liquid. Relative permeabilities calculated from flow rate and pressure data show that the sum of the relative permeabilities of the two phases is much less than 1, indicating that each phase interferes strongly with the flow of the other. Comparison of the relative permeability curves with typical curves for porous media (Corey curves) show that the phase interference is stronger in fractures than in typical porous media

Management of pediatric polytrauma patients is one of the most difficult challenges for orthopaedic surgeons. Multisystem injuries frequently include complex orthopaedic surgical problems that require intervention. The physiology and anatomy of children and adolescent trauma patients differ from the physiology and anatomy of an adult trauma patient, which alters the types of injuries sustained and the ideal methods for management. Errors of pediatric polytrauma care are included in two broad categories: missed injuries and inadequate fracture treatment. Diagnoses may be missed most frequently because of a surgeon's inability to reliably assess patients who have traumatic brain injuries and painful distracting injuries. Cervical spine injuries are particularly difficult to identify in a child with polytrauma and may have devastating consequences. In children who have multiple injuries, the stabilization of long bone fractures with pediatric fixation techniques, such as elastic nails and other implants, allows for easier care and more rapid mobilization compared with cast treatments. Adolescent polytrauma patients who are approaching skeletal maturity, however, are ideally treated as adults to avoid complications, such as loss of fixation, and to speed rehabilitation.

Lasting disability and further falls are common and costly problems in older people following fall-related lower limb and pelvic fractures. Exercise interventions can improve mobility after fracture and reduce falls in older people, however the optimal approach to rehabilitation after fall-related lower limb and pelvic fracture is unclear. This randomised controlled trial aims to evaluate the effects of an exercise and fall prevention self-management intervention on mobility-related disability and falls in older people following fall-related lower limb or pelvic fracture. Cost-effectiveness of the intervention will also be investigated. A randomised controlled trial with concealed allocation, assessor blinding for physical performance tests and intention-to-treat analysis will be conducted. Three hundred and fifty people aged 60 years and over with a fall-related lower limb or pelvic fracture, who are living at home or in a low care residential aged care facility and have completed active rehabilitation, will be recruited. Participants will be randomised to receive a 12-month intervention or usual care. The intervention group will receive ten home visits from a physiotherapist to prescribe an individualised exercise program with motivational interviewing, plus fall prevention education through individualised advice from the physiotherapist or attendance at the group based "Stepping On" program (seven two-hour group sessions). Participants will be followed for a 12-month period. Primary outcome measures will be mobility-related disability and falls. Secondary outcomes will include measures of balance and mobility, falls risk, physical activity, walking aid use, frailty, pain, nutrition, falls efficacy, mood, positive and negative affect, quality of life, assistance required, hospital readmission, and health-system and community-service contact. This study will determine the effect and cost-effectiveness of this exercise self management intervention on mobility-related

Despite the increasing popularity of operative treatment in adolescent tibia fractures, casting remains a viable first-line treatment. Because the selection bias in published reports does not allow direct comparison between casting and flexible nail treatment of closed pediatric tibia fractures, it is unclear whether flexible nailing offers any advantages over casting. This overview discusses parameters of acceptable alignment, indications, techniques for successful reduction and casting, subsequent inpatient and outpatient management including wedging of casted tibia fractures, expected outcomes, and comparison of casting with flexible nailing. As with any orthopaedic procedure, careful attention to patient selection, indications, and detail facilitates successful cast treatment in this older pediatric population.

Condylar fractures in pediatric patients occur frequently, often with minimal pain and discomfort. Thus, these fractures in children are overlooked during emergency care. Condylar fractures can be treated conservatively or by open reduction. As a rule, very good healing results are achieved by conservative treatment. In these cases, jaw function restoration using physiotherapy at an early stage can prevent complications such as asymmetry, interference in the facial growth, and ankylosis. The purpose of this case report was to discuss the peculiarities of treatment of mandibular condyle fractures in pediatric patients and report a case in which the condyles were successfully treated conservatively in a 10-year-old patient. The case was followed up for seven years.

To determine the prevalence of fear of falling (FoF) in patients after a hip fracture, to investigate the relation with time after fracture, and to assess associations between FoF and other psychological factors. Cross-sectional study performed between September 2010 and March 2011 in elderly patients after a hip fracture. Ten postacute geriatric rehabilitation wards in Dutch nursing homes. A total of 100 patients aged ≥65 years with a hip fracture admitted to a geriatric rehabilitation ward. FoF and related concepts such as falls-related self-efficacy, depression, and anxiety were measured by means of self-assessment instruments. Of all patients, 36% had a little FoF and 27% had quite a bit or very much FoF. Scores on the Falls Efficacy Scale-International were 30.6 in the first 4 weeks after hip fracture, 35.6 in the second 4 weeks, and 29.4 in the period ≥8 weeks after fracture. In these 3 periods, the prevalence rates of FoF were 62%, 68%, and 59%, respectively. Significant correlations were found between FoF and anxiety (P falls-related self-efficacy. During rehabilitation, FoF is greatest in the second 4 weeks after hip fracture. More studies are needed to explore the determinants of FoF and develop interventions to reduce FoF and improve outcome after rehabilitation. Copyright © 2013. Published by Elsevier Inc.

2016-01-01

The role of impact interface characteristics on the biomechanics and patterns of cranial fracture has not been investigated in detail, and especially for the pediatric head. In this study, infant porcine skulls aged 2-19 days were dropped with an energy to cause fracturing onto four surfaces varying in stiffness from a rigid plate to one covered with plush carpeting. Results showed that heads dropped onto the rigid surface produced more extensive cranial fracturing than onto carpeted surfaces. Contact forces generated at fracture initiation and the overall maximum contact forces were generally lower for the rigid than carpeted impacts. While the degree of cranial fracturing from impacts onto the heavy carpeted surface was comparable to that of lower-energy rigid surface impacts, there were fewer diastatic fractures. This suggests that characteristics of the cranial fracture patterns may be used to differentiate energy level from impact interface in pediatric forensic cases. © 2015 American Academy of Forensic Sciences.

Geothermal-Related Thermo-Elastic Fracture Analysis by Numerical Manifold Method

Directory of Open Access Journals (Sweden)

Jun He

2018-05-01

Full Text Available One significant factor influencing geothermal energy exploitation is the variation of the mechanical properties of rock in high temperature environments. Since rock is typically a heterogeneous granular material, thermal fracturing frequently occurs in the rock when the ambient temperature changes, which can greatly influence the geothermal energy exploitation. A numerical method based on the numerical manifold method (NMM is developed in this study to simulate the thermo-elastic fracturing of rocklike granular materials. The Voronoi tessellation is incorporated into the pre-processor of NMM to represent the grain structure. A contact-based heat transfer model is developed to reflect heat interaction among grains. Based on the model, the transient thermal conduction algorithm for granular materials is established. To simulate the cohesion effects among grains and the fracturing process between grains, a damage-based contact fracture model is developed to improve the contact algorithm of NMM. In the developed numerical method, the heat interaction among grains as well as the heat transfer inside each solid grain are both simulated. Additionally, as damage evolution and fracturing at grain interfaces are also considered, the developed numerical method is applicable to simulate the geothermal-related thermal fracturing process.

Pavlova, Olga M; Ryabykh, Sergey O; Burcev, Alexander V; Gubin, Alexander V

2018-06-01

To analyze clinical and radiologic features of pathologic atlantoaxial displacement (PAAD) in pediatric patients and to compose a treatment algorithm for anomaly-related PAAD. Criteria of different types of PAAD and treatment algorithms have been widely reported in the literature but are difficult to apply to patients with odontoid abnormalities, C2-C3 block, spina bifida C1, and children. We evaluated results of treatment of 29 pediatric patients with PAAD caused by congenital anomalies of the craniovertebral junction (CVJ), treated in Ilizarov Center in 2009-2017, including 20 patients with atlantoaxial displacement (AAD) and 9 patients with atlantoaxial rotatory fixation. There were 14 males (48.3%) and 15 females (51.7%). We singled out 3 groups of patients: nonsyndromic (6 patients, 20.7%), Klippel-Feil syndrome (13 patients, 44.8%), and syndromic (10 patients, 34.5%). Odontoid abnormalities and C1 dysplasia were widely represented in the syndromic group. Local symptoms predominated in the nonsyndromic and KFS groups. In the syndromic group, all patients had AAD and myelopathy. A pronounced decrease of space available for chord C1 and increase of anterior atlantodental interval were noted compared with other groups. We present a unified treatment algorithm of pediatric anomaly-related PAAD. Syndromic AAD are often accompanied by anterior and central dislocation and myelopathy and atlantooccipital dissociation. These patients require early aggressive surgical treatment. Nonsyndromic and Klippel-Feil syndrome AAD, atlantoaxial subluxation, and atlantoaxial fixation often manifest by local symptoms and need to eliminate CVJ instability. Existing classifications of symptomatic atlantoaxial displacement are not always suitable for patients with CVJ abnormalities. Copyright © 2018 Elsevier Inc. All rights reserved.

In this prospective study, 13 randomly selected patients underwent treatment for zygomatic-complex fractures (2 site fractures) and mandibular fractures using 1.5 / 2 / 2.5-mm INION CPS biodegradable plates and screws. To assess the fixation of zygomatic-complex and mandibular fractures with biodegradable copolymer osteosynthesis system. In randomly selected 13 patients, zygomatic-complex and mandibular fractures were plated using resorbable plates and screws using Champy's principle. All the cases were evaluated clinically and radiologically for the type of fracture, need for the intermaxillary fixation (IMF) and its duration, duration of surgery, fixation at operation, state of reduction at operation, state of bone union after operation, anatomic reduction, paresthesia, occlusal discrepancies, soft tissue infection, immediate and late inflammatory reactions related to biodegradation process, and any need for the removal of the plates. Descriptives, Frequencies, and Chi-square test were used. In our study, the age group range was 5 to 55 years. Road traffic accidents accounted for the majority of patients six, (46.2%). Postoperative occlusal discrepancies were found in seven patients as mild to moderate, which resolved with IMF for 1-8 weeks. There were minimal complications seen and only as soft tissue infection. Use of biodegradable osteosynthesis system is a reliable alternative method for the fixation of zygomatic-complex and mandibular fractures. The biodegradable system still needs to be refined in material quality and handling to match the stability achieved with metal system. Biodegradable plates and screws is an ideal system for pediatric fractures with favorable outcome.

The aim of this study was to compare the efficiency of resorbable and metallic plates in open reduction and internal fixation of mandible fractures in children. Thirty-one patients (mean age, 8.05 years; range 20 months-14 years) were operated on various fractures of the mandible (26 [60.4%] symphysis- parasymphysis, 12 [27.9%] condylar-subcondylar fractures, 5 [11.6%] angulus and ramus fractures). Twelve patients were treated with resorbable plates and 19 patients with metallic plates. Mean follow-up time was 41 months (11-74 months) in the metallic hardware group and was 22 months (8-35 months) in the resorbable plate group. Both groups were investigated for primary bone healing, complications, number of operations, and mandibular growth. The results were discussed below. Both groups demonstrated primary bone healing. Minor complications were similar in both groups. The metallic group involved secondary operations for plate removal. Mandibular growth was satisfactory in both groups. Resorbable plates cost more than the metallic ones; however, when the secondary operations are included in the total cost, resorbable plates were favourable. As mandibular growth and complication parameters are similar in both groups, resorbable plates are favored due to avoidance of potential odontogenic injury, elimination of long-term foreign body retention and provision of adequate stability for rapid bone healing. However, learning curve and concerns for decreased stability against heavy forces of mastication accompanied with the resorbable plates when compared to the metallic ones should be kept in mind.

We report on a 21-day-old infant with healing posterior rib fractures that were noted after a chiropractic visit for colic. Chiropractors are the third largest group of health care professionals in the United States, and colic is the leading complaint for pediatric chiropractic care. Rib fractures, specifically when posterior, are traditionally considered to be secondary to nonaccidental trauma. Thorough investigation is necessary to rule out bone fragility and genetic disorders, but patient history is key when evaluating unexplained fractures.

Low back pain (LBP) and hip pain frequently occur during pregnancy and postpartum period. Although pelvic and mechanic lesions of the soft tissues are most responsible for the etiology, sacral fracture is also one of the rare causes. A 32-year-old primigravid patient presented with LBP and right hip pain which started 3 days after vaginal delivery. Although direct radiographic examination was normal, magnetic resonance imaging of the sacrum revealed sacral stress fracture. Lumbar spine and femoral bone mineral density showed osteoporosis as a risk factor. There were no other risk factors such as trauma, excessive weight gain, and strenuous physical activity. It is considered that the patient had sacral fatigue and insufficiency fracture in intrapartum period. The patient's symptoms subsided in 3 months after physical therapy and rest. In conclusion, sacral fractures during pregnancy and postpartum period, especially resulting from childbirth, are very rare. To date, there are two cases in the literature. In cases who even do not have risk factors related to vaginal delivery such as high birth weight infant and the use of forceps, exc., sacral fracture should be considered in the differential diagnosis of LBP and hip pain started soon after child birth. Pregnancy-related osteoporosis may lead to fracture during vaginal delivery.

Adult tibial intercondylar eminence fracture: evaluation with MR imaging

2002-01-01

Tibial intercondylar eminence (TIE) fractures are well described in the pediatric orthopedic literature. Adult TIEs are much less common, and limited literature exists on the subject. Adult knee hyperextension injuries commonly result in anterior cruciate ligament (ACL) injury; however, with significant trauma, a TIE enters the differential diagnosis. Identification and classification of TIE fractures typically has been provided by radiography. The incidence of concomitant injuries with magnetic resonance (MR) imaging in patients with adult TIE fractures has not been determined. We present a case of an adult type III TIE fracture seen on radiography that only with further MR imaging revealed a concomitant lateral tibial plateau fracture. Utilization of MR imaging altered the surgeon's course of treatment and postoperative care. Radiographic and MR images and a review of the literature are provided. (orig.)

OBJECTIVE The emphasis on health-related quality of life (HRQOL) outcomes is increasing, along with an emphasis on evidence-based medicine. However, there is a notable paucity of validated HRQOL instruments for the pediatric population. Furthermore, no standardization or consensus currently exists concerning which HRQOL outcome measures ought to be used in pediatric neurosurgery. The authors wished to identify HRQOL outcomes used in pediatric neurosurgery research over the past 10 years, their frequency, and usage trends. METHODS Three top pediatric neurosurgical journals were reviewed for the decade from 2005 to 2014 for clinical studies of pediatric neurosurgical procedures that report HRQOL outcomes. Similar studies in the peer-reviewed journal Pediatrics were also used as a benchmark. Publication year, level of evidence, and HRQOL outcomes were collected for each article. RESULTS A total of 31 HRQOL studies were published in the pediatric neurosurgical literature over the study period. By comparison, there were 55 such articles in Pediatrics. The number of publications using HRQOL instruments showed a significant positive trend over time for Pediatrics (B = 0.62, p = 0.02) but did not increase significantly over time for the 3 neurosurgical journals (B = 0.12, p = 0.5). The authors identified a total of 46 different HRQOL instruments used across all journals. Within the neurosurgical journals, the Hydrocephalus Outcome Questionnaire (HOQ) (24%) was the most frequently used, followed by the Health Utilities Index (HUI) (16%), the Pediatric Quality of Life Inventory (PedsQL) (12%), and the 36-Item Short Form Health Survey (SF-36) (12%). Of the 55 articles identified in Pediatrics, 22 (40%) used a version of the PedsQL. No neurosurgical study reached above Level 4 on the Oxford Centre for Evidence-Based Medicine (OCEBM) system. However, multiple studies from Pediatrics achieved OCEBM Level 3, several were categorized as Level 2, and one reached Level 1

Diet is considered an important factor for bone health, but is composed of a wide variety of foods containing complex combinations of nutrients. Therefore we investigated the relationship between dietary patterns and fall-related fractures in the elderly. We designed a population-based prospective survey of 1178 elderly people in Japan in 2002. Dietary intake was assessed with a 75-item food frequency questionnaire (FFQ), from which dietary patterns were created by factor analysis from 27 food groups. The frequency of fall-related fracture was investigated based on insurance claim records from 2002 until 2006. The relationship between the incidence of fall-related fracture and modifiable factors, including dietary patterns, were examined. The Cox proportional hazards regression model was used to examine the relationships between dietary patterns and incidence of fall-related fracture with adjustment for age, gender, Body Mass Index (BMI) and energy intake. Among 877 participants who agreed to a 4 year follow-up, 28 suffered from a fall-related fracture. Three dietary patterns were identified: mainly vegetable, mainly meat and mainly traditional Japanese. The moderately confirmed (see statistical methods) groups with a Meat pattern showed a reduced risk of fall-related fracture (Hazard ratio = 0.36, 95% CI = 0.13 - 0.94) after adjustment for age, gender, BMI and energy intake. The Vegetable pattern showed a significant risk increase (Hazard ratio = 2.67, 95% CI = 1.03 - 6.90) after adjustment for age, gender and BMI. The Traditional Japanese pattern had no relationship to the risk of fall-related fracture. The results of this study have the potential to reduce fall-related fracture risk in elderly Japanese. The results should be interpreted in light of the overall low meat intake of the Japanese population.

Posterior rib fractures are highly indicative of non-accidental trauma (NAT) in infants. Since 2000, the "two-thumbs" technique for cardiopulmonary resuscitation (CPR) of newborns and infants has been recommended by the American Heart Association (AHA). This technique is similar to the grip on an infant's thorax while shaking. Is it possible that posterior rib fractures in newborns and infants could be caused by the "two-thumbs" technique? Using computerized databases from three German children's hospitals, we identified all infants less than 12 months old who underwent professional CPR within a 10-year period. We included all infants with anterior-posterior chest radiographs taken after CPR. Exclusion criteria were sternotomy, osteopenia, various other bone diseases and NAT. The radiographs were independently reviewed by the Chief of Pediatric Radiology (MB) and a Senior Pediatrician, Head of the local Child Protection Team (IF). Eighty infants with 546 chest radiographs were identified, and 50 of those infants underwent CPR immediately after birth. Data concerning the length of CPR was available for 41 infants. The mean length of CPR was 11min (range: 1-180min, median: 3min). On average, there were seven radiographs per infant. A total of 39 infants had a follow-up radiograph after at least 10 days. No rib fracture was visible on any chest X-ray. The results of this study suggest rib fracture after the use of the "two-thumbs" CPR technique is uncommon. Thus, there should be careful consideration of abuse when these fractures are identified, regardless of whether CPR was performed and what technique used. The discovery of rib fractures in an infant who has undergone CPR without underlying bone disease or major trauma warrants a full child protection investigation. Copyright © 2014 Elsevier Ltd.

McFarland fractures represent a type of oblique medial malleolar fracture in children that can be challenging to diagnose and treat. A 14-year-old junior league soccer player with a Salter Harris type IV McFarland fracture presented late, as the initial routine two views radiological assessment failed to reveal a clear fracture line. The addition of a mortise ankle view led to the correct diagnosis and subsequent MRI findings guided nonsurgical treatment with an excellent outcome. The debate between obtaining two or three views in closed pediatric ankle injuries according to the so-called Ottawa rules and the usefulness of magnetic resonance imaging (MRI) in the decision making for the choice of treatment of McFarland fractures are discussed in this case report.

Full Text Available Patella fracture is uncommon in pediatric age group and their patella is better preserved in any class of patella fracture. We reported a case of a 13-year-old male with right patella fracture nonunion. He had open reduction and internal fixation using tension band wire device. Fracture union was monitored with serial radiographs and he was followed up for 60 weeks. There was articular surface step after surgical fixation of the patella fracture. At 34 weeks postoperative, there was complete remodeling of the articular surface with good knee function after removal of the tension band wire. Children have good capacity of bone remodeling after fracture. Little retropatella step in a child after patella fracture surgical fixation will remodel with healing.

Successful treatment of pediatric IgG4 related systemic disease with mycophenolate mofetil: case report and a review of the pediatric autoimmune pancreatitis literature

Directory of Open Access Journals (Sweden)

Cron Randy Q

2011-01-01

Full Text Available Abstract Autoimmune pancreatitis is frequently associated with elevated serum and tissue IgG4 levels in the adult population, but there are few reports of pediatric autoimmune pancreatitis, and even fewer reports of IgG4 related systemic disease in a pediatric population. The standard of care treatment in adults is systemic corticosteroids with resolution of symptoms in most cases; however, multiple courses of corticosteroids are occasionally required and some patients require long term corticosteroids. In these instances, steroid sparing disease modify treatments are in demand. We describe a 13-year-old girl with IgG4 related systemic disease who presented with chronic recurrent autoimmune pancreatitis resulting in surgical intervention for obstructive hyperbilirubinemia and chronic corticosteroid treatment. In addition, she developed fibrosing medianstinitis as part of her IgG4 related systemic disease. She was eventually successfully treated with mycophenolate mofetil allowing for discontinuation of corticosteroids. This is the first reported use of mycophenolate mofetil for IgG4 related pancreatitis. Although autoimmune pancreatitis as part of IgG4 related systemic disease is rarely reported in pediatrics, autoimmune pancreatitis is also characterized as idiopathic fibrosing pancreatitis. All pediatric autoimmune pancreatitis cases reported in the world medical literature were identified via a PUBMED search and are reviewed herein. Twelve reports of pediatric autoimmune pancreatitis were identified, most of which were treated with corticosteroids or surgical approaches. Most case reports failed to report IgG4 levels, so it remains unclear how commonly IgG4 related autoimmune pancreatitis occurs during childhood. Increased evaluation of IgG4 levels in patients with autoimmune pancreatitis may shed further light on the association of IgG4 with pancreatitis and the underlying pathophysiology.

Sport related stress fracture of the clavicle with non-union: Case report and review

Science.gov (United States)

Constantinou, Demitri; Kastanos, Konstantinos

2008-01-01

Stress fractures are relatively uncommon sports injuries and when they do occur, are mostly found in the lower limb. Stress fractures of the clavicle are particularly rare, having been described in a number of non-sport related pathologies, such as nervous tics and post radical neck dissection. In sport, there have only been seven cases reported in the literature. We report on a clavicle stress fracture in a 47-year-old male, partaking in recreational weight lifting activities. This is the first reported case of a non-union stress fracture of the clavicle. The patient underwent an open reduction and internal fixation and made a full recovery. PMID:21264151

Full Text Available Peak bone mass is established predominately during childhood and adolescence. It is an important determinant of future resistance to osteoporosis and fractures to gain bone mass during growth. The issue of low bone density in children and adolescents has recently attracted much attention and the use of pediatric dual-energy X-ray absorptiometry (DXA is increasing. The process of interpretation of pediatric DXA results is different from that of adults because normal bone mineral density (BMD of children varies by age, body size, pubertal stage, skeletal maturation, sex, and ethnicity. Thus, an appropriate normal BMD Z-score reference value with Z-score should be used to detect and manage low BMD. Z-scores below -2.0 are generally considered a low BMD to pediatrician even though diagnoses of osteoporosis in children and adolescents are usually only made in the presence of at least one fragility fracture. This article will review the basic knowledge and practical guidelines on pediatric DXA based on the International Society for Clinical Densitometry (ISCD Pediatric Official Positions. Also discussed are the characteristics of normal Korean children and adolescents with respect to BMD development. The objective of this review is to help pediatricians to understand when DXA will be useful and how to interpret pediatric DXA reports in the clinical practice for management of children with the potential to develop osteoporosis in adulthood.

The traditional belief that obesity is protective against osteoporosis has been questioned. Recent epidemiologic studies show that body fat itself may be a risk factor for osteoporosis and bone fractures. Accumulating evidence suggests that metabolic syndrome and the individual components of metabolic syndrome such as hypertension, increased triglycerides, and reduced high-density lipoprotein cholesterol are also risk factors for low bone mineral density. Using a cross sectional study design, we evaluated the associations between obesity or metabolic syndrome and bone mineral density (BMD) or vertebral fracture. A total of 907 postmenopausal healthy female subjects, aged 60-79 years, were recruited from woman hospitals in Seoul, South Korea. BMD, vetebral fracture, bone markers, and body composition including body weight, body mass index (BMI), percentage body fat, and waist circumference were measured. After adjusting for age, smoking status, alcohol consumption, total calcium intake, and total energy intake, waist circumference was negatively related to BMD of all sites (lumbar BMD p = 0.037, all sites of femur BMD p related to BMD of all sites (p related to femoral trochanter BMD (p = 0.0366) and was lower in the control group than the fracture group (p = 0.011). In contrast to the effect favorable body weight on bone mineral density, high percentage body fat and waist circumference are related to low BMD and a vertebral fracture. Some components of metabolic syndrome were related to BMD and a vertebral fracture.

The objectives of this study were twofold: (1) to examine the prevalence of emotional symptoms among children and adolescents with a sports-related concussion (SRC) who were referred to a multidisciplinary pediatric concussion program and (2) to examine the prevalence, clinical features, risk factors, and management of postinjury psychiatric outcomes among those in this clinical population. The authors conducted a retrospective chart review of all patients with SRC referred to a multidisciplinary pediatric concussion program between September 2013 and October 2014. Clinical assessments carried out by a single neurosurgeon included clinical history, physical examination, and Post-Concussion Symptom Scale (PCSS) scoring. Postinjury psychiatric outcomes were defined as a subjective worsening of symptoms of a preinjury psychiatric disorder or new and isolated suicidal ideation or diagnosis of a novel psychiatric disorder (NPD). An NPD was defined as a newly diagnosed psychiatric disorder that occurred in a patient with or without a lifetime preinjury psychiatric disorder after a concussion. Clinical resources, therapeutic interventions, and clinical and return-to-play outcomes are summarized. One hundred seventy-four patients (mean age 14.2 years, 61.5% male) were included in the study. At least 1 emotional symptom was reported in 49.4% of the patients, and the median emotional PCSS subscore was 4 (interquartile range 1-8) among those who reported at least 1 emotional symptom. Overall, 20 (11.5%) of the patients met the study criteria for a postinjury psychiatric outcome, including 14 patients with an NPD, 2 patients with isolated suicidal ideation, and 4 patients with worsening symptoms of a preinjury psychiatric disorder. Female sex, a higher initial PCSS score, a higher emotional PCSS subscore, presence of a preinjury psychiatric history, and presence of a family history of psychiatric illness were significantly associated with postinjury psychiatric outcomes

Aim: To compare the radiographic results of paediatric forearm fracture reduced with and without fluoroscopic enhancement to investigate whether fractures reduced under fluoroscopic guidance would have smaller residual deformities and lower rates of re-reduction and surgery. Materials and methods: A retrospective cohort analysis was conducted comparing paediatric patients with acute forearm fracture in two trauma centres. Demographics and radiographic data from paediatric forearm fractures treated in Trauma Centre A with the aid of a C-arm fluoroscopy were compared to those treated without fluoroscopy in Trauma Centre B. Re-reduction, late displacement, post-reduction deformity, and need for surgical intervention were compared between the two groups. Results: The cohort included 229 children (175 boys and 54 girls, mean age 9.41±3.2 years, range 1–16 years) with unilateral forearm fractures (83 manipulated with fluoroscopy and 146 without). Thirty-four (15%) children underwent re-reduction procedures in the emergency department. Fifty-three (23%) children had secondary displacement in the cast, of which 18 were operated on, 20 were re-manipulated, and the remaining 15 were kept in the cast with an acceptable deformity. Twenty-nine additional children underwent operation for reasons other than secondary displacement. There were no significant differences in re-reduction and surgery rates or in post-reduction deformities between the two groups. Conclusion: The use of fluoroscopy during reduction of forearm fractures in the paediatric population apparently does not have a significant effect on patient outcomes. Reductions performed without fluoroscopy were comparably accurate in correcting deformities in both coronal and sagittal planes. - Highlights: • Compared outcomes of pediatric forearm fracture reduction with and without fluoroscopy. • The use of fluoroscopy during reduction of forearm fractures in the pediatric population apparently does not have a

Full Text Available SummaryObjective:to compare the efficacy of two analgesia protocols (ketamine versus morphine associated with midazolam for the reduction of dislocations or closed fractures in children.Methods:randomized clinical trial comparing morphine (0.1mg/kg; max 5mg and ketamine (2.0mg/kg, max 70mg associated with midazolam (0.2mg/kg; max 10mg in the reduction of dislocations or closed fractures in children treated at the pediatrics emergency room (October 2010 and September 2011. The groups were compared in terms of the times to perform the procedures, analgesia, parent satisfaction and orthopedic team.Results:13 patients were allocated to ketamine and 12 to morphine, without differences in relation to age, weight, gender, type of injury, and pain scale before the intervention. There was no failure in any of the groups, no differences in time to start the intervention and overall procedure time. The average hospital stay time was similar (ketamine = 10.8+5.1h versus morphine = 12.3+4.4hs; p=0.447. The median pain (faces pain scale scores after the procedure was 2 in both groups. Amnesia was noted in 92.3% (ketamine and 83.3% (morphine (p=0.904. Parents said they were very satisfied in relation to the analgesic intervention (84.6% in the ketamine group and 66.6% in the morphine group; p=0.296. The satisfaction of the orthopedist regarding the intervention was 92.3% in the ketamine group and 75% in the morphine group (p=0.222.Conclusion:by producing results similar to morphine, ketamine can be considered as an excellent option in pain management and helps in the reduction of dislocations and closed fractures in pediatric emergency rooms.

Challenges of Fracture Management for Adults With Osteogenesis Imperfecta.

Science.gov (United States)

Gil, Joseph A; DeFroda, Steven F; Sindhu, Kunal; Cruz, Aristides I; Daniels, Alan H

2017-01-01

Osteogenesis imperfecta is caused by qualitative or quantitative defects in type I collagen. Although often considered a disease with primarily pediatric manifestations, more than 25% of lifetime fractures are reported to occur in adulthood. General care of adults with osteogenesis imperfecta involves measures to preserve bone density, regular monitoring of hearing and dentition, and maintenance of muscle strength through physical therapy. Surgical stabilization of fractures in these patients can be challenging because of low bone mineral density, preexisting skeletal deformities, or obstruction by instrumentation from previous surgeries. Additionally, unique perioperative considerations exist when operatively managing fractures in patients with osteogenesis imperfecta. To date, there is little high-quality literature to help guide the optimal treatment of fractures in adult patients with osteogenesis imperfecta. [Orthopedics. 2017; 40(1):e17-e22.].

Weiss, Joshua P; Sawhney, Raja

2016-08-01

Fractures of the mandibular condyle have provided a lasting source of controversy in the field of facial trauma. Concerns regarding facial nerve injury as well as reasonable functional outcomes with closed management led to a reluctance to treat with an open operative intervention. This article reviews how incorporating new technologies and surgical methods have changed the treatment paradigm. Multiple large studies and meta-analyses continue to demonstrate superior outcomes for condylar fractures when managed surgically. Innovations, including endoscopic techniques, three-dimensional miniplates, and angled drills provide increased options in the treatment of condylar fractures. The literature on pediatric condylar fractures is limited and continues to favor a more conservative approach. There continues to be mounting evidence in radiographic, quality of life, and functional outcome studies to support open reduction with internal fixation for the treatment of condylar fractures in patients with malocclusion, significant displacement, or dislocation of the temporomandibular joint. The utilization of three-dimensional trapezoidal miniplates has shown improved outcomes and theoretically enhanced biomechanical properties when compared with traditional fixation with single or double miniplates. Endoscopic-assisted techniques can decrease surgical morbidity, but are technically challenging, require skilled assistants, and utilize specialized equipment.

Lumbar spondylolysis, a stress fracture of the pars interarticularis, is prevalent in adolescent athletes. Recent advances in diagnostic tools and techniques enable early diagnosis before these fractures progress to complete fractures through the pars. However, because patients often consult family physicians for primary care of low back pain and these physicians may not have access to diagnostic modalities such as magnetic resonance imaging (MRI) and computed tomography, stress fractures can be missed. This study surveyed the prevalence of symptomatic spondylolysis in pediatric patients who consulted an orthopedic clinic for primary care and investigated whether such acute stress fractures may be overlooked without MRI. The prospective study investigated 264 patients who were younger than 19 years and had low back pain. Of the 153 patients (58.0%) with low back pain persisting for longer than 2 weeks, 136 who agreed to undergo MRI were included in the study. This group included 11 elementary school students, 71 junior high school students, and 54 high school students. The overall prevalence of lumbar spondylolysis was 39.7% (54 of 136) and was 9.3% in elementary school students (5 of 11, 45.5%), 59.3% in junior high school students (32 of 71, 45.1%), and 31.5% in high school students (17 of 54, 31.5%). All 54 patients with spondylolysis had a history of athletic activity. Primary care physicians should recognize that approximately 40% of pediatric patients presenting with low back pain persisting for longer than 2 weeks may have spondylolysis and should consider MRI in those with a history of athletic activity. Because the spine is immature in this age group, almost half of affected elementary school and junior high school students may have lumbar spondylolysis. [Orthopedics. 2016; 39(3):e434-e437.].

2005-01-01

Proximal femoral fractures in children are rare, pathologic fractures being extremely rare. Despite many meanings these fractures are still "unsolved" there are some definite rules for treatment of true accidental injuries. Pathologic fractures are outstanding with their extremely rare incidence. The aim of the study is to overview a large clinical material, find out the incidence of this pathologic fracture, the extent and shape of the unicameral bone cyst (UBC), specific therapeutic approach, technical problems of eventual osteosynthesis, number of reoperations and sequels. Altogether 49 children with 50 accidental and pathologic fractures of proximal part of the femur treated in the Regional Pediatric Trauma Centre of the Department of Pediatric and Trauma Surgery, 3rd Faculty of Medicine, Charles University, Prague. Retrospective and prospective study of children (0 to 15 years of age) treated with proximal femoral accidental and pathologic fractures during the 20 year period (from August 1984 to November 2004). Classification of fractures according to Delbet and Colonna. Diagnosis of bone cyst with plain X-rays, eventually CT scans. During the 20 years period (August 1984 to November 2004) 49 children with 50 proximal femoral fractures were treated in the Department. Four patients sustained a pathologic fracture through an unicameral bone cyst. Two of these latter children were treated by an open reduction and osteosynthesis with the use of the proximal femoral AO-ASIF angled-plate and two children nonoperatively using skeletal traction because of impossibility of insertion of the osteosynthetic material without a damage of the growth plate. Subsequent operations of the UBC were necessary in these two children. All four patients recovered well without sequels. Pathologic fractures in UBC are usually treated nonoperatively and the cyst itself is treated after fracture healing. Proximal femoral impairment is the exception from this rule because of weigh bearing

Demand is increasing for esthetic restorations in pediatric dentistry. When full coverage is indicated, one option is to use esthetic stainless steel crowns (SSCs). However, this type of crown is prone to fracture. The purpose of this study was to evaluate the fracture resistance of 3 types of esthetic SSCs. Esthetic SSCs for first primary mandibular molars were cemented to idealized epoxy dies with glass ionomer cement. The die-crown units were fractured on a universal testing machine. The force was delivered by a stainless steel ball fixture, set in a uniaxial lever to replicate a cusp contact, with a crosshead speed of 1 mm/min. The differences among the 3 types of crown, in terms of force required to fracture, were compared statistically by 1-way analysis of variance. Pairwise comparisons were performed with Fisher's protected least significant difference test, at an overall significance level of 5%. The force required to fracture, expressed as average ± standard error, did not differ significantly among the 3 brands of esthetic SSCs: 1730 N ± 50 N, 1826 N ± 62 N and 1671 N ± 68 N, respectively (p = 0.19), well below the maximum bite force of pediatric patients determined in a previous study. Esthetic SSCs should be able to resist occlusal forces over short clinical periods. However, long-term occlusal loading and fatigue failures should be taken into account when evaluating the success of this type of crown.

Our purpose was to investigate longitudinally health-related quality of life (HRQOL) outcomes and related factors up to 2 years post-pediatric SCT. A total of 99 mothers of patients, aged 1.5-17 years, completed two standardized HRQOL questionnaires, generic and disease specific (DS), about the child, and reported on their own symptoms of depression and family function pre-SCT, 12 and 24 months post-SCT. Clinical (diagnosis, radiation), child (age) and family (maternal depression) information was also obtained. Significant improvement in physical and psychosocial HRQOL from pre-SCT to 1 or 2 years post-SCT was reported. Survivors of ALL were reported to have poorer physical and psychosocial HRQOL than survivors of solid tumors on the DS measure. Maternal depression was negatively associated with physical and psychosocial HRQOL. Maternal education (higher) at pre-SCT predicted improvements in physical domains 2 years post-SCT; mother's age (older) and child's age (younger) also predicted improvements of physical and emotional HRQOL. We conclude that survivors of pediatric SCT improved physical and psychosocial HRQOL by 1 and 2 years post-SCT. Older survivors whose mothers are younger and distressed, with lower education at SCT have compromised HRQOL compared to other survivors. This study has important implications for the care of SCT survivors and their families.

To investigate the association between serum levels of 25-hydroxyvitamin D and the occurrence of simultaneous fractures of the upper limb in older women who sustain a fall-related fracture of the hip. Cross-sectional study. We investigated 472 of 480 white women consecutively admitted to a rehabilitation hospital because of a fall-related hip fracture. Twenty-seven (5.7%) of the 472 women sustained a concomitant upper-limb fracture of either distal radius (20 women) or proximal humerus (seven women). We assessed serum levels of 25-hydroxyvitamin D 14.2 ± 4.1 (mean ± SD) days after surgical repair of the hip fracture in the 472 women by an immunoenzymatic assay. Twenty-five-hydroxyvitamin D levels were significantly lower in the 27 women with concomitant fractures of both hip and upper limb than in the remaining 445 hip-fracture women: mean ± SD values were 6.5 ± 5.0 ng/ml and 11.7 ± 10.4 ng/ml respectively in the two groups (mean difference between groups 5.2 ng/ml: 95% CI 1.2-9.2; p=0.011). Low levels of 25-hydroxyvitamin D were significantly associated with concomitant fractures of the upper limb (p=0.017), after adjustment for eight potential confounders including age, height, weight, hip-fracture type, cognitive impairment, neurologic impairment, previous hip fracture, and previous upper-limb fracture. Low levels of 25-hydroxyvitamin D were significantly associated with concomitant upper-limb fractures in our sample of older women with a fall-related fracture of the hip. Preventing vitamin D deficiency may lower the incidence of simultaneous fractures due to a singe fall in elderly women. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Relative permeability of fractured wellbore cement: an experimental investigation using electrical resistivity monitoring for moisture content

Science.gov (United States)

Um, W.; Rod, K. A.; Strickland, C. E.

2016-12-01

Permeability is a critical parameter needed to understand flow in subsurface environments; it is particularly important in deep subsurface reservoirs where multiphase fluid flow is common, such as carbon sequestration and geothermal reservoirs. Cement is used in the annulus of wellbores due to its low permeable properties to seal aquifers, reducing leaks to adjacent strata. Extreme subsurface environments of CO2 storage and geothermal production conditions will eventually reduce the cement integrity, propagating fracture networks and increasing the permeability for air and/or water. To date, there have been no reproducible experimental investigations of relative permeability in fractured wellbore cement published. To address this gap, we conducted a series of experiments using fractured Portland cement monoliths with increasing fracture networks. The monolith cylinder sides were jacketed with heavy-duty moisture-seal heat-shrink tubing, then fractured using shear force applied via a hydraulic press. Fractures were generated with different severity for each of three monoliths. Stainless steel endcaps were fixed to the monoliths using the same shrink-wrapped jacket. Fracture characteristics were determined using X-ray microtomography and image analysis. Flow controllers were used to control flow of water and air to supply continuous water or water plus air, both of which were delivered through the influent end cap. Effluent air flow was monitored using a flow meter, and water flow was measured gravimetrically. To monitor the effective saturation of the fractures, a RCON2 concrete bulk electrical resistivity test device was attached across both endcaps and a 0.1M NaNO3 brine was used as the transport fluid to improve resistivity measurements. Water content correlated to resistivity measurements with a r2 > 0.96. Data from the experiments was evaluated using two relative permeability models, the Corey-curve, often used for modeling relative permeability in porous media

The current study reassesses the prevalence of fragility fractures and lifetime costs in the Eastern Province of Saudi Arabia. Forty-two percent (391) of the fractures were at the neck of the femur, and 38.6 % (354) were inter-trochanteric fractures. The overall incidence was assessed to be 7528 (1,300,336 population 55 years or older) with the direct cost of SR564.75 million ($150.60 million). A National Fracture Registry and osteoporosis awareness programs are recommended. Proximal femur fragility fractures are reported to be increasing worldwide due to increased life expectancy. The current study is carried out to assess the incidence of such fractures in the Eastern Province of Saudi Arabia and to assess the costs incurred in managing them annually. Finally, by extrapolating the data, the study can calculate the overall economic burden in Saudi Arabia. The data of fragility proximal femur fractures was collected from 24 of 28 hospitals in the Eastern Province. The data included age, sex, mode of injury, type of fracture, prescribed drug (and its cost), and length of hospital stay. Population statistics were obtained from the Department of Statistics of the Saudi Arabian government Web site. Twenty-four hospitals (85 %) participated in the study. A total of 780 fractures were sustained by 681 patients. Length of stay in the hospital averaged 23.28 ± 13.08 days. The projected fracture rate from all the hospitals would be 917 (an incidence of 5.81/1000), with a total cost of SR68.77 million. Further extrapolation showed that the overall incidence could be 7528 (1,300,336 population 55 years or older) with the direct cost of SR564.75 million ($150.60 million). Osteoporosis-related femoral fractures in Saudi Arabia are significant causes of morbidity besides incurring economic burden. We believe that a National Fracture Registry needs to be established, and osteoporosis awareness programs should be instituted in every part of Saudi Arabia so that these patients can

Femoral shaft fractures are a common and temporarily disabling injury in children. Recent advances in orthopedic traumatology have led us at the Hospital Universitario del Valle, in Cali, Colombia, to perform a case series observational study with the use of a more aggressive approach with the new endomedullar titanium nails (TENs) in children suffering femur shaft fractures, in a closed procedure performed under image intensification. The main purpose of this study was to evaluate the outcome of 30 children treated with these nails. Pediatric femoral shaft fractures are more common in males with approximately a 2.75:1 male to female ratio. The age distribution is bimodal, with peaks in the younger than 5 years and mid-teenage groups (10-14 years) because of the increased incidence of high-energy trauma in teenage children (mean age: 9 years). Overall, TENs allowed rapid mobilization with few complications. The results were excellent or satisfactory in our cases. No child lost rotational alignment in the postoperative period. Irritation of the soft tissue near the knee by the nail tip occurred in one patient. As indications, implantation technique, and aftercare are refined, TENs may prove to be the ideal implant to stabilize most pediatric femur shaft fractures, avoiding the prolonged immobilization and complications of traction and spica cast

Diastatic skull fractures (DSFs) in children are difficult to detect in skull radiographs before they develop into growing skull fractures; therefore, little information is available on this topic. However, recent advances in 3-dimensional (3D) computed tomography (CT) imaging technology have enabled more accurate diagnoses of almost all forms of skull fracture. The present study was undertaken to document the clinical characteristics of DSFs in children and to determine whether 3D CT enhances diagnostic accuracy. Two hundred and ninety-two children younger than 12 years with skull fractures underwent simple skull radiography, 2-dimensional (2D) CT, and 3DCT. Results were compared with respect to fracture type, location, associated lesions, and accuracy of diagnosis. DSFs were diagnosed in 44 (15.7%) of children with skull fractures. Twenty-two patients had DSFs only, and the other 22 had DSFs combined with compound or mixed skull fractures. The most common fracture locations were the occipitomastoid (25%) and lambdoid (15.9%). Accompanying lesions consisted of subgaleal hemorrhages (42/44), epidural hemorrhages (32/44), pneumocephalus (17/44), and subdural hemorrhages (3/44). A total of 17 surgical procedures were performed on 15 of the 44 patients. Fourteen and 19 patients were confirmed to have DSFs by skull radiography and 2D CT, respectively, but 3D CT detected DSFs in 43 of the 44 children (P skull radiography or 2D CT for detecting DSFs. This finding indicates that 3D CT should be used routinely rather than 2D CT for the assessment of pediatric head trauma. Copyright © 2017 Elsevier Inc. All rights reserved.

To explore the impact of titanium implant on the growth and development of pediatric mandible after suffering from mandibular fracture and undergoing open reduction and internal fixation (ORIF) compared with those that underwent titanium plate removal postoperatively. Fifteen pediatric patients with mandibular fracture who underwent ORIF were included in this study. Eight patients did not undergo titanium implant removal postoperatively, whereas the other seven patients underwent the routine. The postoperative data of the pediatrics were collected for comparative analysis by taking the patients' frontal and lateral photos, recording the inter-incisor distance, and measuring the height of mandibular ramus, length of the mandibular body, and combined length of the mandible in three-dimensional reconstruction image. All patients had acceptable facial contour, mouth opening, and occlusion, without obvious abnormalities. The radiography showed no significant difference between the bilateral mandibular lengths in the two groups of patients (P>0.05). The titanium plants have no significant impact on the growth and development of pediatric mandible postoperatively; hence, the question on whether the titanium plates should be removed or not may be neglected. The removal operation may lead to secondary trauma; thus, performing titanium plate removal routinely is not recommended.

Mandibular fractures are the most common facial fractures seen in hospitalized children and their incidence increases with age. Treatment options include soft diet, intermaxillary fixation with eyelet wires, arch bars, circummandibular wiring, or stents. Alternative options include open reduction and internal fixation through either an intraoral or extraoral approach. Many factors complicate the management of pediatric mixed-dentition mandibular fractures: tooth eruption, short roots, developing tooth buds and growth issues. One major factor is the inherent instability of the occlusion in the mixed deciduous-permanent tooth phase. This case report documents a child in mixed dentition period with a complication arising due to direct fixation of the fractured mandible.

Fracture systems comprise many fractures that may be grouped into sets based on their orientation, type and relative age. The fractures are often arranged in a network that involves fracture branches that interact with one another. Interacting fractures are termed geometrically coupled when they share an intersection line and/or kinematically coupled when the displacements, stresses and strains of one fracture influences those of the other. Fracture interactions are characterised in terms of the following. 1) Fracture type: for example, whether they have opening (e.g., joints, veins, dykes), closing (stylolites, compaction bands), shearing (e.g., faults, deformation bands) or mixed-mode displacements. 2) Geometry (e.g., relative orientations) and topology (the arrangement of the fractures, including their connectivity). 3) Chronology: the relative ages of the fractures. 4) Kinematics: the displacement distributions of the interacting fractures. It is also suggested that interaction can be characterised in terms of mechanics, e.g., the effects of the interaction on the stress field. It is insufficient to describe only the components of a fracture network, with fuller understanding coming from determining the interactions between the different components of the network.

There is a need to provide more efficient surgical training methods for orthopaedic residents. E-learning could possibly increase resident surgical preparedness, confidence, and comfort for surgery. Using closed reduction and pinning of pediatric supracondylar humeral fractures as the index case, we hypothesized that e-learning could increase resident knowledge acquisition for case preparation in the operating room. An e-learning surgical training module was created on the Computer Enhanced Visual Learning platform. The module provides a detailed and focused road map of the procedure utilizing a multimedia format. A multisite prospective randomized controlled study design compared residents who used a textbook for case preparation (control group) with residents who used the same textbook plus completed the e-learning module (test group). All subjects completed a sixty-question test on the theory and methods of the case. After completion of the test, the control group then completed the module as well. All subjects were surveyed on their opinion regarding the effectiveness of the module after performing an actual surgical case. Twenty-eight subjects with no previous experience in this surgery were enrolled at four academic centers. Subjects were randomized into two equal groups. The test group scored significantly better (p < 0.001) and demonstrated competence on the test compared with the control group; the mean correct test score (and standard deviation) was 90.9% ± 6.8% for the test group and 73.5% ± 6.4% for the control group. All residents surveyed (n = 27) agreed that the module is a useful supplement to traditional methods for case preparation and twenty-two of twenty-seven residents agreed that it reduced their anxiety during the case and improved their attention to surgical detail. E-learning using the Computer Enhanced Visual Learning platform significantly improved preparedness, confidence, and comfort with percutaneous closed reduction and pinning of a

Medical malpractice is the primary method by which people who believe they have suffered an injury in the course of medical care seek compensation in the United States and Canada. An increasing body of research demonstrates that failure to correctly diagnose is the most common allegation made in malpractice claims against radiologists. Since the 1994 survey by the Society of Chairmen of Radiology in Children's Hospitals (SCORCH), no other published studies have specifically examined the frequency or clinical context of malpractice claims against pediatric radiologists or arising from pediatric imaging interpretation. We hypothesize that the frequency, character and outcome of malpractice claims made against pediatric radiologists differ from those seen in general radiology practice. We searched the Controlled Risk Insurance Co. (CRICO) Strategies' Comparative Benchmarking System (CBS), a private repository of approximately 350,000 open and closed medical malpractice claims in the United States, for claims related to pediatric radiology. We further queried these cases for the major allegation, the clinical environment in which the claim arose, the clinical severity of the alleged injury, indemnity paid (if payment was made), primary imaging modality involved (if applicable) and primary International Classification of Diseases, 9th revision (ICD-9) diagnosis underlying the claim. There were a total of 27,056 fully coded claims of medical malpractice in the CBS database in the 5-year period between Jan. 1, 2010, and Dec. 31, 2014. Of these, 1,472 cases (5.4%) involved patients younger than 18 years. Radiology was the primary service responsible for 71/1,472 (4.8%) pediatric cases.

Identifying Fracture Types and Relative Ages Using Fluid Inclusion Stratigraphy

Energy Technology Data Exchange (ETDEWEB)

Dilley, Lorie M.; Norman, David; Owens, Lara

2008-06-30

Enhanced Geothermal Systems (EGS) are designed to recover heat from the subsurface by mechanically creating fractures in subsurface rocks. Understanding the life cycle of a fracture in a geothermal system is fundamental to the development of techniques for creating fractures. Recognizing the stage of a fracture, whether it is currently open and transmitting fluids; if it recently has closed; or if it is an ancient fracture would assist in targeting areas for further fracture stimulation. Identifying dense fracture areas as well as large open fractures from small fracture systems will also assist in fracture stimulation selection. Geothermal systems are constantly generating fractures, and fluids and gases passing through rocks in these systems leave small fluid and gas samples trapped in healed microfractures. Fluid inclusions trapped in minerals as the fractures heal are characteristic of the fluids that formed them, and this signature can be seen in fluid inclusion gas analysis. Our hypothesis is that fractures over their life cycle have different chemical signatures that we can see in fluid inclusion gas analysis and by using the new method of fluid inclusion stratigraphy (FIS) the different stages of fractures, along with an estimate of fracture size can be identified during the well drilling process. We have shown with this study that it is possible to identify fracture locations using FIS and that different fractures have different chemical signatures however that signature is somewhat dependent upon rock type. Open, active fractures correlate with increase concentrations of CO2, N2, Ar, and to a lesser extent H2O. These fractures would be targets for further enhancement. The usefulness of this method is that it is low cost alternative to current well logging techniques and can be done as a well is being drilled.

A retrospective review was performed to evaluate the outcomes and complications following heterotopic ossification (HO) resection and lysis of adhesion procedures for posttraumatic contracture, after combat-related open elbow fractures. From 2004 to 2011, HO resection was performed on 30 blast-injured elbows at a mean 10 months after injury. Injuries included 8 (27%) Gustilo-Anderson type II fractures, 8 (27%) type III-A, 10 (33%) III-B, and 4 (13%) III-C. Mean preoperative flexion-extension range of motion (ROM) was 36.4°, compared with mean postoperative ROM of 83.6°. Mean gain of motion was 47.2°. Traumatic brain injury, need for flap, and nerve injury did not appear to have a significant effect on preoperative or postoperative ROM. Complications included one fracture, six recurrent contractures, and one nerve injury. The results and complications of HO resection for elbow contracture following high-energy, open injuries from blast trauma are generally comparable to those reported for HO resection following lower energy, closed injuries.

With increasing participation and intensity of training in youth sports in the United States, the incidence of sports-related injuries is increasing, and the types of injuries are shifting. In this article, the authors review sports injuries of the lower extremity, including both acute and overuse injuries, that are common in or specific to the pediatric population. Common traumatic injuries that occur in individuals of all ages (eg, tears of the acetabular labrum and anterior cruciate ligament) are not addressed, although these occur routinely in pediatric sports. However, some injuries that occur almost exclusively in high-level athletes (eg, athletic pubalgia) are reviewed to increase awareness and understanding of these entities among pediatric radiologists who may not be familiar with them and thus may not look for them. Injuries are described according to their location (ie, hip, knee, or foot and ankle) and pathologic process (eg, apophysitis, osteochondritis dissecans). Examples of abnormalities and normal variants of the anatomy that are often misdiagnosed are provided. The injuries reviewed represent a common and growing subset of pathologic processes about which all pediatric and musculoskeletal radiologists should be knowledgeable. Understanding physeal injury is especially important because missed diagnoses can lead to premature physeal closure and osteoarthritis. © RSNA, 2016.

Objective measurements can be used to identify people with risks of falls, but many frail elderly adults cannot complete physical performance tests. The study examined the relationship between a subjective risk rating of specific tasks (SRRST) to screen for fall risks and falls and fall-related fractures in frail elderly people. The SRRST was investigated in 5,062 individuals aged 65 years or older who were utilized day-care services. The SRRST comprised 7 dichotomous questions to screen for fall risks during movements and behaviours such as walking, transferring, and wandering. The history of falls and fall-related fractures during the previous year was reported by participants or determined from an interview with the participant's family and care staff. All SRRST items showed significant differences between the participants with and without falls and fall-related fractures. In multiple logistic regression analysis adjusted for age, sex, diseases, and behavioural variables, the SRRST score was independently associated with history of falls and fractures. Odds ratios for those in the high-risk SRRST group (≥ 5 points) compared with the no risk SRRST group (0 point) were 6.15 (p fall, 15.04 (p falls, and 5.05 (p fall-related fractures. The results remained essentially unchanged in subgroup analysis accounting for locomotion status. These results suggest that subjective ratings by care staff can be utilized to determine the risks of falls and fall-related fractures in the frail elderly, however, these preliminary results require confirmation in further prospective research.

Hip fracture risk is known to increase with physical inactivity and decrease with obesity, but there is little information on their combined effects. We report on the separate and combined effects of body mass index (BMI) and physical activity on hospital admissions for hip fracture among postmenopausal women in a large prospective UK study. Baseline information on body size, physical activity, and other relevant factors was collected in 1996-2001, and participants were followed for incident hip fractures by record linkage to National Health Service (NHS) hospital admission data. Cox regression was used to calculate adjusted relative risks of hip fracture. Among 925,345 postmenopausal women followed for an average of 6.2 years, 2582 were admitted to hospital with an incident hip fracture. Hip fracture risk increased with decreasing BMI: Compared with obese women (BMI of 30+ kg/m(2) ), relative risks were 1.71 [95% confidence interval (CI) 1.47-1.97)] for BMI of 25.0 to 29.9 kg/m(2) and 2.55 (95% CI 2.22-2.94) for BMI of 20.0 to 24.9 kg/m(2). The increase in fracture risk per unit decrease in BMI was significantly greater among lean women than among overweight women (p physical inactivity was associated with an increased risk of hip fracture. There was no significant interaction between the relative effects of BMI and physical activity. For women who reported that they took any exercise versus no exercise, the adjusted relative risk of hip fracture was 0.68 (95% CI 0.62-0.75), with similar results for strenuous exercise. In this large cohort of postmenopausal women, BMI and physical activity had independent effects on hip fracture risk. Copyright © 2011 American Society for Bone and Mineral Research.

Effect of Fireworks Laws on Pediatric Fireworks-Related Burn Injuries.

Myers, John; Lehna, Carlee

Changes in U.S. fireworks laws have allowed younger children to purchase fireworks. In addition, the changes have allowed individuals to purchase more powerful fireworks. The purpose of this study is to examine the epidemiology of pediatric firework-related burn injuries among a nationally representative sample of the United States for the years 2006 to 2012. We examined inpatient admissions for pediatric firework-related burn patients from 2006 to 2012 using the nationwide inpatient sample and examined emergency department admissions using the nationwide emergency department sample. Both data sources are part of the Healthcare Cost and Utilization Project. Trajectories over time were evaluated. A total of 3193 injuries represented an estimated 90,257 firework-related injuries treated in the United States from 2006 to 2012. A majority of injuries were managed in the emergency department (n = 2008, 62.9%). The incidence generally increased over time; increasing from 4.28 per 100,000 population in 2006 to 5.12 per 100,000 population in 2012, P = .019. However, the proportion of injuries requiring inpatient admission (28.9% in 2006 to 50.0% in 2012, P fireworks laws may have had a modest effect on incidence of related injuries and the age of purchaser. However, it has had a dramatic effect on the severity of the related injuries, resulting in more inpatient admissions and longer length of stay in the hospital. Preventative methods should be taken to reduce the rate and severity of firework-related injuries among U.S. youths.

Optimizing pediatric interdental fixation by use of a paramedian palatal fixation site.

McNichols, Colton H; Hatef, Daniel A; Cole, Patrick D; Hollier, Larry H

2012-03-01

Condylar fractures are the most common injury seen in pediatric mandibular trauma. These injuries often cannot be adequately stabilized by conservative techniques such as splinting. The pediatric condyle fracture often requires a period of intermaxillary fixation. Because of the characteristics of the developing dentition, circumdental wiring is often not possible. Surgeons commonly achieve interdental stabilization by the connection of a circum-mandibular wire and a second wire placed through a drill hole in the piriform aperture. This method can be problematic in the young patient whose palatal suture is still patent. In this brief technical note, the use of a paramedian drill hole through the palate posterior to the maxillary incisors is described. It is believed that this method is superior to other techniques because it avoids injury to the deciduous tooth buds and allows for the maxillary wire to be seated in more structurally sound tissues.

Healing patterns of clavicular birth injuries as a guide to fracture dating in cases of possible infant abuse

Walters, Michele M.; Forbes, Peter W.; Buonomo, Carlo; Kleinman, Paul K.

2014-01-01

Dating fractures is critical in cases of suspected infant abuse. There are little scientific data to guide radiologists, and dating is generally based on personal experience and conventional wisdom. Since birth-related clavicular fractures are not immobilized and their age is known, we propose that an assessment of these injuries may serve as a guide for dating inflicted fractures in young infants, acknowledging that patterns observed in the clavicle may not be entirely generalizable to other bones injured in the setting of abuse. One hundred thirty-one radiographs of presumed birth-related clavicular fractures in infants between 0 and 3 months of age were reviewed by two pediatric radiologists with 30 and 15 years' experience. Readers were asked to evaluate images based on several parameters of fracture healing, with a focus on subperiosteal new bone formation (SPNBF) and callus formation. SPNBF and callus were each evaluated with regard to presence, thickness and character. Responses were correlated with known fracture ages. SPNBF was rarely seen in fractures less than 7 days old and was most often present by 10 days. Callus formation was rarely seen in fractures less than 9 days old and was most often present by 15 days. SPNBF thickness increased with fracture age and the character of SPNBF evolved from single-layered to solid/multilayered. Callus thickness decreased with fracture age and callus matrix evolved from soft to intermediate to hard in character. There is an evolution in clavicular fracture healing in young infants that follows a predictable pattern. These findings afford the prospect that predictable patterns of infant clavicular fracture healing can provide an evidence base that may be applicable in cases of suspected infant abuse. (orig.)

Pediatric blunt or sharp laryngotracheal injuries are infrequent because of the softer cartilages and the protection of the prominent mandible. These injuries usually occur secondary to striking furniture or via the "clothesline" injury. We present five cases of pediatric laryngotracheal injury (thyroid cartilage, true vocal cords, cricoid cartilage, cricotracheal junction, and posterior tracheal wall). We examined the need for intubation, need for tracheostomy, length of intubation, length of hospital stay, interval until direct laryngoscopy, use of steroids, post-injury swallowing, and post-injury phonation. Three of the five patients were intubated either prior to arrival or upon arrival to the emergency department. Two of the patients underwent direct laryngoscopy on the day of arrival. Three patients received steroids. CT (computed tomography) was not helpful in diagnosis or decision regarding treatment. The patients with thyroid cartilage fracture, cricoid cartilage fracture, cricotracheal separation, and posterior tracheal wall tear required open repair. The tracheal wall injury, cricoid fracture, and cricotracheal separation were repaired with sutures and the thyroid cartilage fracture with a plate and screws. One tracheal stent was placed. Two open repairs were performed within 24h of injury. The patient with posterior tracheal wall injury experienced persistent dysphagia and dysphonia, which may have been secondary to intraoperative dissection. Dyspnea was not necessarily indicative of the severity of injury in our patients. CT added little information about the integrity of the larynx not already known by physical examination. Open repair was usually indicated for the blunt neck injuries in our series. Oral intubation proved less difficult than tracheostomy in our patient with cricoid cartilage fracture.

Dog bites represent lesions commonly found in Hospital Emergency Clinic. This type of lesion may cause severe harm to patients, but it rarely affects the underlying bone structure causes facial fracture. This study aims to illustrate a rare clinical case in which a pediatric patient presented a comminuted fracture in the mandible which evolved into a unilateral avulsion of the mandibular condyle, body fractures as well as a mandibular ramus and hemiface that had been deformed, with multiple lacerations and loss of soft-tissue mass. Intermaxillary fixation was performed using the Ivy method, followed by internal rigid fixation using miniplates and screws in attempt to reconstruct the child's mandible. After 2 years of follow-up, a satisfactory esthetics and functional results could be observed. © 2011 John Wiley & Sons A/S.

Full Text Available Abstract Background Osteoporosis is a serious health problem that worsens the quality of life and the survival rate of individuals with this disease on account the osteoporotic fractures. Studies have long focused on women, and its presence in men has been underestimated. While many studies conducted in different countries mainly assess health-related quality of life and identify fracture risks factors in women, few data are available on a Spanish male population. Methods/Design Observational study. Study population Men ≥ 40 years of age with/without diagnosed osteoporosis and with/without osteoporotic fracture included by their family doctor. Measurements The relationship between customary clinical risk factors for osteoporotic fracture and health-related quality of life in a Spanish male population. A telephone questionnaire on health-related quality of life is made. Statistical analysis The association between qualitative variables will be assessed by the Chi-square test. The distribution of quantitative variables by Student's t-test. If the conditions for using this test are not met, the non-parametric Mann-Whitney's U test will be used. The validation of the results obtained by the FRAX™ tool will be performed by way of the Hosmer-Lemeshow test and by calculating the area under the Receiver Operating Characteristic (ROC curve (AUC. All tests will be performed with a confidence intervals set at 95%. Discussion The applicability and usefulness of Health-related quality of life (HRQOL studies are well documented in many countries. These studies allow implementing cost-effective measures in cases of a given disease and reducing the costly consequences derived therefrom. This study attempts to provide objective data on how quality of life is affected by the clinical aspects involved in osteoporosis in a Spanish male population and can be useful as well in cost utility analyses conducted by health authorities. The sample selected is not based

Full Text Available Osteoarthritis is the leading cause of total hip replacement, accounting for more than 80% of all total hip replacements. Emerging evidence suggests that osteoarthritis has a chronic inflammatory component to its pathogenesis similar to age-related macular degeneration. We evaluated the association between age-related macular degeneration and total hip replacement as proxy for severe osteoarthritis or fractured neck of femur in the Melbourne Collaborative Cohort Study. 20,744 participants had complete data on both age-related macular degeneration assessed from colour fundus photographs taken during 2003-2007 and total hip replacement. Total hip replacements due to hip osteoarthritis and fractured neck of femur during 2001-2011 were identified by linking the cohort records to the Australian Orthopedic Association National Joint Replacement Registry. Logistic regression was used to examine the association between age-related macular degeneration and risk of total hip replacement due to osteoarthritis and fracture separately, adjusted for confounders. There were 791 cases of total hip replacement for osteoarthritis and 102 cases of total hip replacement due to fractured neck of femur. After adjustment for age, sex, body mass index, smoking, and grouped country of birth, intermediate age-related macular degeneration was directly associated with total hip replacement for osteoarthritis (odds ratio 1.22, 95% CI 1.00-1.49. Late age-related macular degeneration was directly associated with total hip replacement due to fractured neck of femur (odds ratio 5.21, 95% CI2.25-12.02. The association between intermediate age-related macular degeneration and an increased 10-year incidence of total hip replacement due to osteoarthritis suggests the possibility of similar inflammatory processes underlying both chronic diseases. The association of late age-related macular degeneration with an increased 10-year incidence of total hip replacement due to fractured

Social pediatrics teaches pediatric residents how to understand disease within their patients' social, environmental and political contexts. It's an essential component of pediatric residency training; however there is very little literature that addresses how such a broad-ranging topic can be taught effectively. The aim of this study was to determine and characterize social pediatric education in our pediatric residency training in order to identify strengths and gaps. A social pediatrics curriculum map was developed, attending to 3 different dimensions: (1) the intended curriculum as prescribed by the Objectives of Training for Pediatrics of the Royal College of Physicians and Surgeons of Canada (RCPSC), (2) the formal curriculum defined by rotation-specific learning objectives, and (3) the informal/hidden curriculum as reflected in resident and teacher experiences and perceptions. Forty-one social pediatric learning objectives were extracted from the RCPSC Objectives of Training for Pediatrics, most were listed in the Medical Expert (51%) and Health Advocate competencies (24%). Almost all RCPSC social pediatric learning objectives were identified in more than one rotation and/or seminar. Adolescent Medicine (29.2%), Pediatric Ambulatory Medicine (26.2%) and Developmental Pediatrics (25%) listed the highest proportion of social pediatric learning objectives. Four (10%) RCPSC social pediatric objectives were not explicitly named within learning objectives of the formal curriculum. The informal curriculum revealed that both teachers and residents viewed social pediatrics as integral to all clinical encounters. Perceived barriers to teaching and learning of social pediatrics included time constraints, particularly in a tertiary care environment, and the value of social pediatrics relative to medical expert knowledge. Despite the lack of an explicit thematic presentation of social pediatric learning objectives by the Royal College and residency training program

Osteogenesis imperfecta (OI) is an hereditary disease affecting conective tissue, mainly associated to growth retardation and pathological fractures. OI type I (OI type I), is the mildest, most often, and homogeneous in its fenotype. Vertebral fractures are the most significant complications, associated to skeletical and cardiopulmonary morbidity. To characterize clinically a cohort of children with OI type I. A cohort of OI type I children younger than 20 year old was evaluated. Demographic, clinical, biochemical and radiological data were registered. Sixty seven patients were included, 55% male, 69% resident in the Metropolitan Region. The mean age of diagnose was 2.9 years, 70% presented vertebral fractures on follow-up, mostly thoracic, and 50% before the age of 5 years. Fifty percentage presented vertebral fractures at diagnose, which was about the age of 5 years. Bone metabolic parameters were in the normal range, without significant change at the moment of vertebral fractures. Calcium intake was found to be below American Academy of Pediatrics recommendations at the time of the first fracture. In this study OI type I has an early diagnose, and vertebral fractures show a high incidence, mostly in toddlers. Calcium intake was found to be below reccomended values, and should be closely supervised in these patients.

In the treatment of the mandibular fractures, one of the main principles is to use the least amount of foreign material. We present an alternative technique that the bone grafts harvested from the fracture borders or from the iliac crest were used instead of plates and the fixation was done with screws. In the study including 24 mandible fractures, the bone grafts harvested from the fracture borders were used in the 10 favorable fractures and the bone grafts harvested from the iliac crest were used in the 14 unfavorable fractures. In the combined mandible fractures, four fractures were fixated with titanium plates and the other side with the bone graft. The patients, who were followed up for 12 to 20 months, were evaluated with macroscopic occlusion, panoramic graphs, and three-dimensional computerized tomographs. The advantage of this technique of fixation with the autogenous tissue is reduced infection rates and reduced operation costs. In the pediatric patients, the second session operation of plate removal is not necessary.

Chest CT after pediatric trauma is frequently performed but its clinical impact, particularly with respect to surgical intervention, has not been adequately evaluated. To assess the impact of chest CT compared with chest radiography on pediatric trauma management. Two hundred thirty-five consecutive pediatric trauma patients who had both chest CT and radiography were identified. Images were reviewed and findings were categorized and correlated with subsequent chest interventions, blinded to final outcome and management. Of the 235 children, 38.3% (90/235) had an abnormal chest radiograph and 63.8% (150/235) had an abnormal chest CT (P < 0.0001). Chest interventions followed in 4.7% (11/235); of these, the findings could be made 1 cm above the dome of the liver in 91% (10/11). Findings requiring chest intervention included pneumothorax (PTX) and vertebral fractures. PTX was found on 2.1% (5/235) of chest radiographs and 20.0% (47/235) of chest CTs (P < 0.0001); 1.7% (4/235) of the children received a chest tube for PTX, 0.85% (2/235) seen on chest CT only. Vertebral fractures were present in 3.8% of the children (9/235) and 66.7% (6/9) of those cases were treated with spinal fusion or brace. There were no instances of mediastinal vascular injury. Most intrathoracic findings requiring surgical management in our population were identified in the lower chest and would be included in routine abdominopelvic CT exams; this information needs to be taken into consideration in the diagnostic algorithm of pediatric trauma patients.

Organ transplantation may lead to secondary osteoporosis in children. This study characterized bone histomorphometric findings in pediatric solid organ transplant recipients who were assessed for suspected secondary osteoporosis. Iliac crest biopsies were obtained from 19 children (7.6-18.8 years, 11 male) who had undergone kidney (n = 6), liver (n = 9), or heart (n = 4) transplantation a median 4.6 years (range 0.6-16.3 years) earlier. All patients had received oral glucocorticoids at the time of the biopsy. Of the 19 patients, 21 % had sustained peripheral fractures and 58 % vertebral compression fractures. Nine children (47 %) had a lumbar spine BMD Z-score below -2.0. Histomorphometric analyses showed low trabecular bone volume (bone turnover at biopsy, and low turnover was found in 6 children (32 %), 1 of whom had adynamic bone disease. There was a great heterogeneity in the histological findings in different transplant groups, and the results were unpredictable using non-invasive methods. The observed changes in bone quality (i.e. abnormal turnover rate, thin trabeculae) rather than the actual loss of trabecular bone, might explain the increased fracture risk in pediatric solid organ transplant recipients.

Fracture zones constrained by neutral surfaces in a fault-related fold: Insights from the Kelasu tectonic zone, Kuqa Depression

2017-11-01

Stress variation associated with folding is one of the controlling factors in the development of tectonic fractures, however, little attention has been paid to the influence of neutral surfaces during folding on fracture distribution in a fault-related fold. In this study, we take the Cretaceous Bashijiqike Formation in the Kuqa Depression as an example and analyze the distribution of tectonic fractures in fault-related folds by core observation and logging data analysis. Three fracture zones are identified in a fault-related fold: a tensile zone, a transition zone and a compressive zone, which may be constrained by two neutral surfaces of fold. Well correlation reveals that the tensile zone and the transition zone reach the maximum thickness at the fold hinge and get thinner in the fold limbs. A 2D viscoelastic stress field model of a fault-related fold was constructed to further investigate the mechanism of fracturing. Statistical and numerical analysis reveal that the tensile zone and the transition zone become thicker with decreasing interlimb angle. Stress variation associated with folding is the first level of control over the general pattern of fracture distribution while faulting is a secondary control over the development of local fractures in a fault-related fold.

To investigate the role of a fall risk assessment, using the Downton Fall Risk Index (DFRI), in predicting fall-related injury, fall-related head injury and hip fracture, and death, in a large cohort of older women and men residing in Sweden. Cross sectional observational study. Sweden. Older adults (mean age 82.4 ± 7.8) who had a fall risk assessment using the DFRI at baseline (N = 128,596). Information on all fall-related injuries, all fall-related head injuries and hip fractures, and all-cause mortality was collected from the Swedish Patient Register and Cause of Death Register. The predictive role of DFRI was calculated using Poisson regression models with age, sex, height, weight, and comorbidities as covariates, taking time to outcome or end of study into account. During a median follow-up of 253 days (interquartile range 90-402 days) (>80,000 patient-years), 15,299 participants had a fall-related injury, 2,864 a head injury, and 2,557 a hip fracture, and 23,307 died. High fall risk (DFRI ≥3) independently predicted fall-related injury (hazard ratio (HR) = 1.43, 95% confidence interval (CI) = 1.39-1.49), hip fracture (HR = 1.51, 95% CI =1.38-1.66), head injury (HR = 1.12, 95% CI = 1.03-1.22), and all-cause mortality (HR = 1.39, 95% CI = 1.35-1.43). DFRI more strongly predicted head injury (HR = 1.29, 95% CI = 1.21-1.36 vs HR = 1.08, 95% CI = 1.04-1.11) and hip fracture (HR = 1.41, 95% CI = 1.30-1.53 vs HR = 1.08, 95% CI = 1.05-1.11) in 70-year old men than in 90-year old women (P Fall risk assessment using DFRI independently predicts fall-related injury, fall-related head injury and hip fracture, and all-cause mortality in older men and women, indicating its clinical usefulness to identify individuals who would benefit from interventions. © 2016 The Authors.

A casting technique has been developed for making translucent replicas of the void space of natural rock fractures. Attenuation of light shined through the cast combined with digital image analysis provides a pointwise definition of fracture apertures. The technique has been applied to a fracture specimen from Dixie Valley, Nevada, and the measured void space geometry has been used to develop theoretical predictions of two-phase relative permeability. A strong anisotropy in relative permeabilities has been found, which is caused by highly anisotropic spatial correlations among fracture apertures. 16 refs., 6 figs.

This study characterizes the epidemiology of nonfatal pediatric firework-related injuries in the United States among children and adolescents by analyzing data from the National Electronic Injury Surveillance System from 1990 through 2014. During this 25-year period, an estimated 136 991 (95% CI = 113 574-160 408) children firework-related injuries. The annual injury rate decreased significantly by 30.4% during this period. Most of those injured were male (75.7%), mean patient age was 10.6 years, and 7.6% required hospital admission. The hands (30.0%) were the most commonly injured body region, followed by head and neck (22.2%), and eyes (21.5%). Sixty percent of injuries were burns. Injuries were most commonly associated with firecrackers (26.2%), aerial devices (16.3%), and sparklers (14.3%). Consumer fireworks pose a serious injury risk to pediatric users and bystanders, and families should be encouraged to attend public firework displays rather than use consumer fireworks.

Posttraumatic Proximal Radioulnar Synostosis after Closed Reduction for a Radial Neck and Olecranon Fracture

2018-01-01

Full Text Available Posttraumatic proximal radioulnar synostosis (PPRUS is a severe complication of radial head and neck fractures known to occur after severe injury or operative fixation. Cases of PPRUS occurring after minimally displaced, nonoperatively treated radial neck injuries are, by contrast, extremely rare. Here, we present a pediatric case of PPRUS that developed after a nonoperatively treated minimally displaced radial neck fracture with concomitant olecranon fracture. While more cases are needed to establish the association between this pattern of injury and PPRUS, we recommend that when encountering patients with a minimally displaced radial neck fracture and a concomitant elbow injury, the rare possibility of developing proximal radioulnar synostosis should be considered.

Dental fractures of the permanent maxillary anterior teeth are relatively frequent accidents during childhood. The Efficient diagnosis and treatment of dental injury are important elements in clinical dentistry. This article describes a case of trauma in permanent right central maxillary incisors with tooth fragments embedded in the lower lip. Thorough clinical examination followed by soft tissue radiographs confirmed the presence of a fractured incisal fragment, which was surgically retrieved under local anesthesia. Direct composite restoration was placed. After finishing and polishing, an esthetic and natural-looking restoration was achieved; this completely satisfied the functional and esthetic expectation of the patient and dental team.

Full Text Available Objective: The aim of this study was to evaluate the func­tional and radiological results of the application of intra­medullary fixation with elastic titanium nails in unstable femoral fractures and to determine the factors affecting these results. Methods: A total of 32 patients aged 4-17 years treated with intramedullary elastic nails for a femoral diaphysis fracture between 2001 and 2014 were included. The frac­ture was left side in 12 cases, right side in 18 and bilateral in 2. The fracture pattern was determined as fragmented in 11 cases, short oblique in 11, transverse in 8 and spi­ral in 4. The same surgical technique and postoperative care was applied to all the patients. Sagittal and coronal angle measurements were made from postoperative and follow-up anterior-posterior and lateral radiographs. The mean follow-up period was 54 months (12-156 months. Positive union criteria were accepted as pain-free weight-bearing and callus bridging in at least 3 cortices seen on direct radiographs. Results: Union was achieved in all except one patient. They were able to return to previous activities with full knee and hip joint range of movement. Radiologically, the mean time to union was determined as 9 weeks (range, 6-16 weeks. Limb shortness was determined in 5 (14% patients. No significant association was detected be­tween shortness and fracture pattern. No varus or valgus angulation of >10˚ was determined in any patient. Conclusion: Application of titanium elastic nails in pe­diatric femoral diaphysis fractures is a comfortable, eco­nomic, and reliable method which is allows early weight-bearing.

Spinal cord injuries (SCIs) related to cervical spine (C-spine) fractures can cause significant morbidity and mortality. Aggressive treatment often required to manage instability associated with C-spine fractures is complicated and hazardous in the elderly population. To determine the mortality rate of elderly patients with SCIs related to C-spine fractures and identify factors that contribute toward a higher risk for negative outcomes. Retrospective cohort study at two Level 1 trauma centers. Thirty-seven consecutive patients aged 60 years and older who had SCIs related to C-spine fractures. Level of injury, injury severity, preinjury medical comorbidities, treatment (operative vs. nonoperative), and cause of death. Hospital medical records were reviewed independently. Baseline radiographs and computed tomography or magnetic resonance imaging scans were examined to permit categorization according to the mechanistic classification by Allen and Ferguson of subaxial C-spine injuries. Univariate logistic regression analyses were performed to identify factors related to in-hospital mortality and ambulation at discharge. There were no funding sources or potential conflicts of interest to disclose. The in-hospital mortality rate was 38%. Respiratory failure was the leading cause of death. Preinjury medical comorbidities, age, and operative versus nonoperative treatment did not affect mortality. Injury level at or above C4 was associated with a 7.1 times higher risk of mortality compared with injuries below C4 (p=.01). Complete SCI was associated with a 5.1 times higher risk of mortality compared with incomplete SCI (p=.03). Neurological recovery was uncommon. Apart from severity of initial SCI, no other factor was related to ambulatory disposition at discharge. In this elderly population, neurological recovery was poor and the in-hospital mortality rate was high. The strongest risk factors for mortality were injury level and severity of SCI. Although each case of SCI

OBJECTIVE: To investigate the long-term health-related quality of life (HRQOL) outcomes for patients requiring at least 28 days of pediatric intensive care. DESIGN: Retrospective cohort and prospective follow-up study. SETTING: A 21-bed pediatric intensive care unit (PICU) in a university-affiliated, tertiary referral pediatric hospital. PATIENTS: One hundred ninety-three patients who spent 28 days or longer in the PICU between January 1, 1997 and December 31, 2004. INTERVENTIONS: Quality of life was measured using the Pediatric Quality of Life Inventory (Peds QL 4.0) parent-proxy version at 2 to 10 yrs after discharge. The PedsQL 4.0 is a modular measure of HRQOL, which is reliable in children aged 2 to 18 yrs. It generates a total score and physical, emotional, social, school, and psychosocial subscores. MEASUREMENTS AND MAIN RESULTS: Of the 193 patients, 41 died during their PICU admission and 27 died between PICU discharge and follow-up. Quality of life questionnaires were posted to parents of 108 of the 125 survivors and 70 were returned completed. Forty children (57.1%) had scores indicating a normal quality of life, whereas 30 (42.9%) had scores indicating impaired HRQOL. Of these, 14 (20%) had scores indicating poor quality of life with ongoing disabling health problems requiring hospitalization or the equivalent. CONCLUSIONS: Our results indicate that, while long PICU stay is associated with significant mortality, the long-term HRQOL is normal for the majority of surviving children.

Pediatric DXA: clinical applications

International Nuclear Information System (INIS)

Binkovitz, Larry A.; Sparke, Paul; Henwood, Maria J.

Normal bone mineral accrual requires adequate dietary intake of calcium, vitamin D and other nutrients; hepatic and renal activation of vitamin D; normal hormone levels (thyroid, parathyroid, reproductive and growth hormones); and neuromuscular functioning with sufficient stress upon the skeleton to induce bone deposition. The presence of genetic or acquired diseases and the therapies that are used to treat them can also impact bone health. Since the introduction of clinical DXA in pediatrics in the early 1990s, there has been considerable investigation into the causes of low bone mineral density (BMD) in children. Pediatricians have also become aware of the role adequate bone mass accrual in childhood has in preventing osteoporotic fractures in late adulthood. Additionally, the availability of medications to improve BMD has increased with the development of bisphosphonates. These factors have led to the increased utilization of DXA in pediatrics. This review summarizes much of the previous research regarding BMD in children and is meant to assist radiologists and clinicians with DXA utilization and interpretation. (orig.)

Isolated fracture of the sternum is an uncommon injury in a child. We report two cases of sternal fracture following falls from swings, which illustrate the mechanisms of injury in sternal fracture. One fracture resulted from a flexion compression injury of the thoracic spine, which has very rarely been reported in children. Sternal fracture should be considered in the differential diagnosis of acute chest pain in a child where there has been an activity involving hyperflexion force. (orig.)

In a retrospective population-based study we assessed whether and how self-reported former fractures sustained at the ages of 20-34 are associated with subsequent fractures sustained at the ages of 35-57. The 12,162 women who responded to fracture questions of the baseline postal enquiry (in 1989) of the Kuopio Osteoporosis Study, Finland formed the study population. They reported 589 former and 2092 subsequent fractures. The hazard ratio (HR), with 95% confidence interval (CI), of a subsequent fracture was 1.9 (1.6-2.3) in women with the history of a former fracture compared with women without such a history. A former low-energy wrist fracture was related to subsequent low-energy wrist [HR = 3.7 (2.0-6.8)] and high-energy nonwrist [HR = 2.4 (1.3-4.4)] fractures, whereas former high-energy nonwrist fractures were related only to subsequent high-energy nonwrist [HR = 2.8 (1.9-4.1)] but not to low-energy wrist [HR = 0.7 (0.3-1.8)] fractures. The analysis of bone mineral density (BMD) data of a subsample of premenopausal women who underwent dual x-ray absorptiometry (DXA) during 1989-91 revealed that those with a wrist fracture due to a fall on the same level at the age of 20-34 recorded 6.5% lower spinal (P = 0.140) and 10.5% lower femoral (P = 0.026) BMD than nonfractured women, whereas the corresponding differences for women with a former nonwrist fracture due to high-energy trauma were -1.8% (P = 0.721) and -2.4% (P = 0. 616), respectively. Our results suggest that an early premenopausal, low-energy wrist fracture is an indicator of low peak BMD which predisposes to subsequent fractures in general, whereas early high-energy fractures are mainly indicators of other and more specific extraskeletal factors which mainly predispose to same types of subsequent fractures only.

Full Text Available Abstract Background Objective measurements can be used to identify people with risks of falls, but many frail elderly adults cannot complete physical performance tests. The study examined the relationship between a subjective risk rating of specific tasks (SRRST to screen for fall risks and falls and fall-related fractures in frail elderly people. Methods The SRRST was investigated in 5,062 individuals aged 65 years or older who were utilized day-care services. The SRRST comprised 7 dichotomous questions to screen for fall risks during movements and behaviours such as walking, transferring, and wandering. The history of falls and fall-related fractures during the previous year was reported by participants or determined from an interview with the participant's family and care staff. Results All SRRST items showed significant differences between the participants with and without falls and fall-related fractures. In multiple logistic regression analysis adjusted for age, sex, diseases, and behavioural variables, the SRRST score was independently associated with history of falls and fractures. Odds ratios for those in the high-risk SRRST group (≥ 5 points compared with the no risk SRRST group (0 point were 6.15 (p Conclusion These results suggest that subjective ratings by care staff can be utilized to determine the risks of falls and fall-related fractures in the frail elderly, however, these preliminary results require confirmation in further prospective research.

Full Text Available A “Fishtail deformity” is one of the well-known complications following pediatric lateral condyle or supracondylar fractures of the humerus. We herein report a case of medial condyle fracture (Kilfoyle type III in an 11-year-old boy. He had a transient “fishtail deformity” of the trochlear groove after open reduction and internal fixation. As occurred in the current case, the bone remodeling and the improvement of ischemia of the trochlea after medial condyle fracture may be associated with the likelihood of recovery from transient “fishtail deformity.”

Parenting stress in pediatric inflammatory bowel disease (IBD) has been under-examined. Data validating use of the Pediatric Inventory for Parents (PIP), a measure of parenting stress associated with caring for a chronically ill child, in chronic diseases with intermittent, unpredictable disease courses, such as IBD, are needed. This study presents validity data in support of the PIP in pediatric IBD and examines relations between parenting stress and important psychosocial and medical outcomes. Adolescents (N = 130) with IBD and their caregivers across 3 sites completed measures of parenting stress, family functioning, and emotional/behavioral functioning. Disease severity was also assessed for each participant. The PIP demonstrates excellent internal consistency. Parenting stress was significantly higher among those with unhealthy general family functioning and those with children with borderline or clinically elevated internalizing symptoms. Caregiving stress was greater among parents of youth with more active Crohn's disease. Results supported the reliability and validity of the PIP for assessing caregiving stress in pediatric IBD. Routine assessment of parenting stress is recommended, particularly among parents reporting unhealthy family functioning and parents of youth with borderline or clinically elevated internalizing symptoms and more active disease.

Point-of-care ultrasound (POCUS) has become an integral part of emergency medicine practice. Research evaluating POCUS in the care of pediatric patients has improved the understanding of its potential role in clinical care. Recent work has investigated the ability of pediatric emergency medicine (PEM) physicians to perform a wide array of diagnostic and procedural applications in POCUS ultrasound. Studies have demonstrated that PEM providers are able to identify an array of diseases, including intussusception, pyloric stenosis and appendicitis. Novel applications of ultrasound, such as a cardiac evaluation in the acutely ill patient or identification of skull fractures in the assessment of a patient with head injury, have shown excellent promise in recent studies. These novel applications have the potential to reshape pediatric diagnostic algorithms. Key applications in PEM have been investigated in the recent publications. Further exploration of the ability to integrate ultrasound into routine practice will require larger-scale studies and continued growth of education in the field. The use of ultrasound in clinical practice has the potential to improve safety and efficiency of care in the pediatric emergency department.

To review and compare the epidemiology and treatment of mandibular fractures in subgroups of a pediatric population. We conducted a retrospective review of pediatric patients (age, ≤18 years) with mandibular fractures treated at our institution from January 1996 through November 2011. We identified 122 patients (93 [76%] male) with 216 mandibular fractures. The prevalent mechanisms of injury were motor vehicle accidents (n=52 [43%]), sports injuries (n=24 [20%]), and assault (n=13 [11%]). The most common fracture sites were subcondylar, parasymphyseal, angle, and body. Two patients (2%) were treated conservatively by observation only, 67 (55%) underwent maxillomandibular fixation alone, 41 (34%) underwent maxillomandibular fixation with plate fixation, and 7 (5.7%) underwent plate fixation only. The average duration of maxillomandibular fixation was 26 days (range, 7-49 days). Complications occurred in 11 patients (9.0%) over a mean follow-up of 92 days (range, 21-702 days). Fifty patients (41.0%) had comorbid conditions or a history of mental illness at the time of injury, including attention deficit hyperactivity disorder (n=11 [9%]), mental disorders other than attention deficit hyperactivity disorder (n=23 [19%]), and asthma (n=17 [14%]). Twenty-six patients (21%) had a history of substance use, the most common being tobacco (n=18 [15%]), alcohol (n=13 [11%]), and marijuana (n=11 [9%]). Treatment approach and outcomes were affected by age and fracture characteristics. In addition, a marked proportion of this cohort had preexisting mental disorders and history of substance use, which may have implications on treatment approach.

a linear skull fracture and 54 (49%) did not. The association between scalp hematoma and ICI attenuated but remained significant after excluding patients with linear skull fracture (OR = 3.3, 95% CI = 2.1 to 5.1). Large and boggy and nonfrontal scalp hematomas had the strongest association with the presence of ICI in this large pediatric cohort. Although children 0 to 6 months of age were at highest odds, the presence of a scalp hematoma also independently increased the odds of ICI in older children and adolescents. The presence of a linear skull fracture only partially explained this relation, indicating that ruling out a skull fracture beneath a hematoma does not obviate the risk of intracranial pathology. © 2016 by the Society for Academic Emergency Medicine.

Full Text Available OBJECTIVE: To evaluate the effect the type of hip fracture (femoral neck or trochanteric has on the Health-Related Quality of Life of elderly subjects. METHODS: Forty-five patients with hip fractures (mean 74.30 ± 7.12 years, 24 with a femoral neck fracture and 21 with a trochanteric fracture, completed the 36-item Short Form Health Survey (SF-36 at baseline and four months after fracture. The Health-Related Quality of Life scores were compared according to fracture type, undisplaced and displaced femoral neck fractures, and stable and unstable trochanteric fractures. RESULTS: Compared to baseline, all patients scored lower in the physical functioning, role limitation-physical, bodily pain and vitality categories four months after the fracture had occurred. The SF-36 scores for all the scales did not differ significantly between patients with femoral neck versus trochanteric fractures, or between patients with displaced versus undisplaced femoral neck fractures and stable versus unstable trochanteric fractures. CONCLUSIONS: The mental and physical quality of life of elderly patients with a hip fracture is severely impaired one month after fracture, with partial recovery by the end of the fourth month. The negative impact on the Health-Related Quality of Life did not differ significantly according to fracture type.

To evaluate the association of 64 obesity-related polymorphisms with pediatric-onset type 2 diabetes and other glucose- and insulin-related traits in Mexican children. Case-control and case-sibling designs were followed. We studied 99 patients with pediatric-onset type 2 diabetes, their siblings (n = 101) without diabetes, 83 unrelated pediatric controls and 137 adult controls. Genotypes were determined for 64 single nucleotide polymorphisms, and a possible association was examined between those genotypes and type 2 diabetes and other quantitative traits, after adjusting for age, sex and body mass index. In the case-pediatric control and case-adult control analyses, five polymorphisms were associated with increased likelihood of pediatric-onset type 2 diabetes; only one of these polymorphisms (CADM2/rs1307880) also showed a consistent effect in the case-sibling analysis. The associations in the combined analysis were as follows: ADORA1/rs903361 (OR 1.9, 95% CI 1.2; 3.0); CADM2/rs13078807 (OR 2.2, 95% CI 1.2; 4.0); GNPDA2/rs10938397 (OR 2.2, 95% CI 1.4; 3.7); VEGFA/rs6905288 (OR 1.4, 95% CI 1.1; 2.1) and FTO/rs9939609 (OR 1.8, 95% CI 1.0; 3.2). We also identified 16 polymorphisms nominally associated with quantitative traits in participants without diabetes. ADORA/rs903361, CADM2/rs13078807, GNPDA2/rs10938397, VEGFA/rs6905288 and FTO/rs9939609 are associated with an increased risk of pediatric-onset type 2 diabetes in the Mexican population.

The aim of this case report is to discuss the effect on condylar reduction of botulinum toxin A treatment used in a child with displaced fracture at condylar neck of mandible. A 3-years old boy was admitted to our clinic for incomplete fracture of mandibular symphysis and displaced condylar fracture at the left side. An asymmetrical occlusal splint with intermaxillary fixation was used instead of open reduction and internal fixation because of incomplete fracture of symphysis and possible complications of condyle surgery. However, it was observed that condylar angulation persisted despite this procedure. Thus, botulinum toxin A was administered to masseter, temporalis and pterygoideus medialis muscles. At the end of first month, it was seen that mandibular condyle was almost completely recovered and that fusion was achieved. In conclusion, Botulinum A toxin injection aiming the suppression of masticatory muscle strength facilitates the reduction in the conservative management of displaced condyle in pediatric patients.

To investigate the advantages of using tomosynthesis (TS) compared to radiographs in the detection, characterization, and follow-up of bisphosphonate-related atypical femur fractures (BP-AFF). Eight patients were identified retrospectively who underwent TS for radiographic findings suspicious for BP-AFF. Two radiologists independently interpreted 15 radiographs and 16 TS examinations, indicating the presence or absence of the following: (1) cortical "beaking" on radiographs, (2) radiolucent fracture line on radiographs, and (3) fracture lucency on TS corresponding to the site of radiographic abnormality. Radiation dose data were calculated for radiographs and TS using Monte Carlo analysis. There was agreement on 100 % of radiographs regarding the presence or absence of a cortical beak. Regarding the presence or absence of a fracture lucency, there was agreement on 100 % of TS examinations (Kappa = 1.0) and 73 % of radiographs (Kappa = 0.40 ± 0.24). For the 46 % of radiographs in which one or both radiologists did not visualize a fracture line, there was 100 % agreement for the presence of a fracture line on the corresponding TS. The interobserver agreement for fracture line detection was significantly higher for TS than for radiographs (p = 0.012). The effective radiation dose using TS was approximately 96 % lower compared to radiography. TS outperformed radiographs in the detection and characterization of BP-AFF. TS may also have advantages over radiography for BP-AFF follow-up through its unique ability to visualize fracture healing with lower effective radiation doses to the patient.

OBJECTIVE Traumatic brain injury (TBI) in children is a significant public health concern estimated to result in over 500,000 emergency department (ED) visits and more than 60,000 hospitalizations in the United States annually. Sports activities are one important mechanism leading to pediatric TBI. In this study, the authors characterize the demographics of sports-related TBI in the pediatric population and identify predictors of prolonged hospitalization and of increased morbidity and mortality rates. METHODS Utilizing the National Sample Program of the National Trauma Data Bank (NTDB), the authors retrospectively analyzed sports-related TBI data from children (age 0-17 years) across 5 sports categories: fall or interpersonal contact (FIC), roller sports, skiing/snowboarding, equestrian sports, and aquatic sports. Multivariable regression analysis was used to identify predictors of prolonged length of stay (LOS) in the hospital or intensive care unit (ICU), medical complications, inpatient mortality rates, and hospital discharge disposition. Statistical significance was assessed at α sports-related TBIs were recorded in the NTDB, and these injuries represented 11,614 incidents nationally after sample weighting. Fall or interpersonal contact events were the greatest contributors to sports-related TBI (47.4%). Mild TBI represented 87.1% of the injuries overall. Mean (± SEM) LOSs in the hospital and ICU were 2.68 ± 0.07 days and 2.73 ± 0.12 days, respectively. The overall mortality rate was 0.8%, and the prevalence of medical complications was 2.1% across all patients. Severities of head and extracranial injuries were significant predictors of prolonged hospital and ICU LOSs, medical complications, failure to discharge to home, and death. Hypotension on admission to the ED was a significant predictor of failure to discharge to home (OR 0.05, 95% CI 0.03-0.07, p sports was independently associated with prolonged hospital LOS compared with FIC events (mean increase

To investigate the characteristics of vomiting in pediatric migraineurs and the relationship of vomiting with other migraine-related parameters. The cohort included children and adolescents with migraine attending a headache clinic of a tertiary pediatric medical center from 2010 to 2016. Patients were identified by a retrospective database search. Data were collected from medical files. The presence of vomiting was associated with background and headache-related parameters. The study group included 453 patients, 210 boys (46.4%) and 243 girls (53.6%), of mean age 11.3 ± 3.7 years. Vomiting was reported by 161 patients (35.5%). On comparison of patients with and without vomiting, vomiting was found to be significantly associated with male gender (54% vs 42.1%, P migraine onset (8.0 ± 3. years vs 9.6 ± 3.7 years, P migraine (67% vs 58.7%, P migraine (24.1% vs 10.1%, P migraine in both parents (9.3% vs 3.1%, P = .007), and migraine in either parent (57.5% vs 45.5%, P = .02). The higher rate of vomiting in the younger patients and the patients with awakening pain may be explained by a common underlying pathogenetic mechanism of vomiting and migraine involving autonomic nerve dysfunction/immaturity. The association of vomiting with parental migraine points to a genetic component of vomiting and migraine. It should be noted that some of the findings may simply reflect referral patterns in the tertiary clinic. © 2017 American Headache Society.

Full Text Available Background: Late presentation of humeral lateral condylar fracture in children is a surgical dilemma. Osteosynthesis of the fracture fragment or correction of elbow deformity with osteotomies and ulnar nerve transposition or sometimes both procedures combined is a controversial topic. We retrospectively evaluated open reduction and fixation cases in late presentation of lateral humeral condyle fracture in pediatric cases with regards to union and functional results. Materials and Methods: Twenty two pediatric (≤12 years patients with fractures of lateral condyle presenting 4 weeks or more post injury between the study period of 2006 and 2010 were included. Multiple K-wires / with or without screws along with bone grafting were used. At final evaluation, union (radiologically and elbow function (Liverpool Elbow Score, LES was assessed. Results: There were 19 boys and 3 girls. Followup averaged 33 months. Pain (n=9, swelling (n=6, restriction of elbow motion (n=6, prominence of lateral condylar region (n=4, valgus deformity (n=4 were the main presenting symptoms. Ulnar nerve function was normal in all patients. There were nine Milch type I and 13 type II fractures. Union occurred in 20 cases. One case had malunion and in another case there was resorption of condyle following postoperative infection and avascular necrosis. Prominent lateral condyles (4/12, fish tail appearance (n=7, premature epiphyseal closure (n=2 were other observations. LES averaged 8.12 (range, 6.66-9.54 at final followup. Conclusions: There is high rate of union and satisfactory elbow function in late presenting lateral condyle fractures in children following osteosynthesis attempt. Our study showed poor correlation between patient′s age, duration of late presentation or Milch type I or II and final elbow function as determined by LES.

Dating fractures and fracture movement in the Lac du Bonnet Batholith

This report examines and summarizes all work that has been done from 1980 to the present in determining the age of rock crystallization, fracture initiation, fracture reactivation and rates of fracture movement in the Lac du Bonnet Batholith to provide information for Atomic Energy of Canada Limited's (AECL) Canadian Nuclear Fuel Waste Management Program. Geological and petrographical indicators of relative age (e.g. cross-cutting relationships, sequences of fracture infilling minerals, P-T characteristics of primary and secondary minerals) are calibrated with radiometric age determinations on minerals and whole rock samples, using 87 Rb- 87 Sr, 40 K- 39 Ar, 40 Ar- 39 Ar and fission track methods. Most fractures and fracture zones inclined at low angles are found to be ancient features, first formed in the Early Proterozoic under conditions of deuteric alteration. Following some movement on fractures in the Late Proterozoic and Early Paleozoic, reactivation of fractures during the Pleistocene is established from uranium-series dating methods and use of stable isotopic contents of fracture infilling minerals (mainly calcite). Some indication of movement on fracture zones during the Pleistocene is given by electron spin resonance dating techniques on fault gouge. The slow rate of propagation of fractures is indicated by mineral infillings, their P-T characteristics and U-series calcite ages in a fracture in sparsely fractured rock, accessible from AECL's Underground Research Laboratory. These results collectively indicate that deep fractures observed in the batholith are ancient features and the fracturing and jointing in the upper 200 m is relatively recent (< 1 Ma) and largely a result of stress release.

High patient acuity, heavy workload, and patient deaths can all contribute to work-related stress for pediatric oncology nurses. A new leadership role, the clinical support nurse (CSN), was recently initiated on the oncology unit of a large Canadian pediatric hospital to support frontline staff and reduce some of the stresses related to clinical activity. The CSN assists nurses with complex patient care procedures, provides hands-on education at the bedside, and supports staff in managing challenging family situations. This study explores the effect of the CSN role on the nurses' work-related stress using the Stressor Scale for Pediatric Oncology Nurses. A total of 58 nurses participated in this study for a response rate of 86%. The results show that the intensity of work-related stress experienced by nurses in this study is significantly less (P < .001) on shifts staffed with a CSN compared with shifts without a CSN.

Risk of vertebral insufficiency fractures in relation to compressive strength predicted by quantitative computed tomography

International Nuclear Information System (INIS)

Biggemann, M.; Hilweg, D.; Seidel, S.; Horst, M.; Brinckmann, P.

1991-01-01

Vertebral insufficiency fractures may result from excessive loading of normal and routine loading of osteoporotic spines. Fractures occur when the mechanical load exceeds the vertebral compressive strength, i.e., the maximum load a vertebra can tolerate. Vertebral compressive strength is determined by trabecular bone density and the size of end-plate area. Both parameters can be measured non-invasively by quanti-tative computed tomography (QCT). In 75 patients compressive strength (i.e., trabecular bone density and endplate area) of the vertebra L3 was determined using QCT. In addition, conventional radiographs of the spines were analysed for the prevalence of insufficiency fractures in each case. By relating fracture prevalence to strength, 3 fracture risk groups were found: a high-risk group with strength values of L3 5 kN and a fracture risk near 0 percent. Biomechanical measurements and model calculations indicate that spinal loads of 3 to 4 kN at L3/4 will be common in everyday activities. These data and the results described above suggest that spines with strength values of L3<3 kN are at an extremely high risk of insufficiency fractures in daily life. Advantages of fracture risk assessment by strength determination over risk estimation based on clinically used trabecular bone density measurements are discussed. (author). 18 refs.; 4 figs

Many risk factors have been identified for hip fracture, including female, advanced age, osteoporosis, previous fractures, low body weight or low body mass index, alcohol drinking, smoking, family history of fractures, use of glucocorticoid, factors related to falls, and bone strength. The factors related to falls are number of fall, frail, post stroke, paralysis, muscle weakness, anti-anxiety drugs, anti-depression drugs, and sedatives. Dementia and respiratory disease and others have been reported to be risk factors for secondary hip fracture.

To determine the geographic distribution of childhood diabetes and obesity relative to the supply of US pediatric endocrinologists. Estimation of observed and "index" ratios of children with diabetes (by region and division) and obesity (body mass index >/=95th % for age and sex) (by region and state) to board-certified pediatric endocrinologists. At the national level, the ratio of children with diabetes to pediatric endocrinologists is 290:1, and the ratio of obese children to pediatric endocrinologists is 17,741:1. Ratios of children with diabetes to pediatric endocrinologists in the Midwest (370:1), South (335:1), and West (367:1) are twice as high as in the Northeast (144:1). Across states, there is up to a 19-fold difference in the observed ratios of obese children to pediatric endocrinologists. Under conditions of equitably distributed endocrinologist supply, variation across states would be mitigated considerably. The distribution of children with diabetes and obesity does not parallel the distribution of pediatric endocrinologists in the United States, due largely to geographic disparities in endocrinologist supply. Given the large burden of obese children to endocrinologists, multidisciplinary models of care delivery are essential for the US health care system to address the needs of children with diabetes and obesity.

Full Text Available Background : Femoral neck fractures in children are an uncommon but difficult situation. The aim of our study was to evaluate clinical results of closed reduction internal fixation and primary valgus osteotomy fixed with a tension band wire loop in high angled pediatric femoral neck fractures. Methods : In a prospective nonrandomized study conducted at 2 centres, sixteen children and adolescents with a Pauwel type 2/3 fracture neck femur were taken as participants. The femoral neck fractures were stabilized using closed reduction and internal fixation (6.5 mm noncannulated screw and a primary valgus osteotomy fixed with a tension band wire loop preferably within 24-36 hours of injury. Patients were evaluated to determine complications, clinical and radiological outcome. Results : At a mean post operative follow up of 5 years, union was achieved in all cases. Three patients had AVN and one developed coxavara. Results were evaluated using IOWA hip scores. Thirteen patients had an excellent result while 3 patients had a good result. Conclusion : Use of this technique holds promise in treating these difficult unstable fractures. Although results from a larger series are still awaited yet the use of this technique can safely be extended to stable fractures also, to minimize the incidence of complications as nonunion and AVN.

Two thousand eight hundred ninety-four children and adolescents treated by 243 pediatricians were analyzed. Patients receiving attention deficit hyperactivity disorder (ADHD) medications were at a lower risk of fractures than patients without ADHD medications. The strongest impact was in the age group of 6-9 years. Finally, there was a significant association between therapy duration and fracture risk. The aim of this study was to analyze the impact of ADHD therapy on fracture risk in children treated by German pediatricians. Children and adolescents initially diagnosed with ADHD and fractures between 2010 and 2015 were identified by 243 pediatricians. In this nested case-control study, each ADHD case with a fracture was matched (1:1) to an ADHD control without a fracture for age, gender, index year, and physician. In total, 2894 individuals were available for analysis. The main outcome of the study was the risk of fracture as a function of ADHD therapy. Multivariate logistic regression models were created to determine the effect of ADHD therapy on the risk of fracture in the entire population and in three age-specific subgroups. Patients receiving ADHD medications were at a lower risk of fracture than patients without ADHD medications (OR = 0.61). The impact of ADHD therapy on the risk of fracture was stronger in the age group of 6-9 years (OR = 0.41) than in the age groups of 10-13 years (OR = 0.68) and 14-17 years (OR = 0.74). Finally, a significant correlation was found between therapy duration and fracture risk (OR = 0.71 per month). ADHD therapy was associated with a decrease in the risk of fracture in children and adolescents treated by German pediatricians.

To review the most relevant articles regarding environmental pediatrics, its potential effects on health, and especially its advances in prevention. A literature search was conducted using MEDLINE/PubMed and SciELO databases. Articles from 1990 to 2010 were reviewed, in addition to book chapters related to environmental pediatrics. There is a significant variety of factors that make children highly vulnerable to environmental hazard exposure, which are mainly associated with children's comparatively greater consumption of water, food, and air in relation to body weight. According to the World Health Organization, every year more than 3 million children under the age of 5 die because of environment-related conditions. Approximately 30 to 40% of pediatric diseases are related to environmental factors. Children are constantly exposed to various environmental health hazards, among which the following stand out: contaminated water, lack of adequate sanitation facilities, air pollution, disease vectors, chemical hazards, injuries, and accidents. Nowadays, pediatricians are challenged to address environmental pediatrics health care needs. The pediatric health history needs to be more comprehensive by adding pointed questions to help identify potential environmental risks. Awareness and understanding of the noxious effects of various environmental conditions and knowledge of the related prevention measures will result in timely and adequate interventions that will improve our children's health and development.

There is a lack of dosing guidelines for use in obese children. Moreover, the impact of obesity on drug safety and clinical outcomes is poorly defined. The paucity of information needed for the safe and effective use of drugs in obese patients remains a problem, even after drug approval. To assess the current incorporation of obesity as a covariate in pediatric drug development, the pediatric medical and clinical pharmacology reviews under the Food and Drug Administration (FDA) Amendments Act of 2007 and the FDA Safety and Innovation Act (FDASIA) of 2012 were reviewed for obesity studies. FDA labels were also reviewed for statements addressing obesity in pediatric patients. Forty-five drugs studied in pediatric patients under the FDA Amendments Act were found to have statements and key words in the medical and clinical pharmacology reviews and labels related to obesity. Forty-four products were identified similarly with pediatric studies under FDASIA. Of the 89 product labels identified, none provided dosing information related to obesity. The effect of body mass index on drug pharmacokinetics was mentioned in only 4 labels. We conclude that there is little information presently available to provide guidance related to dosing in obese pediatric patients. Moving forward, regulators, clinicians, and the pharmaceutical industry should consider situations in drug development in which the inclusion of obese patients in pediatric trials is necessary to facilitate the safe and effective use of new drug products in the obese pediatric population. © 2018, The American College of Clinical Pharmacology.

Obesity in childhood is one of the major health issues in pediatric health care today. As expected, the prevalence of obesity-related comorbidities has risen in parallel with that of obesity. Consultation regarding these concomitant diseases and subsequent management by subspecialists, including pediatric gastroenterologists, is now common and has resulted in obesity being recognized as a chronic disease requiring coordination of care. Although medications and even surgery may provide effective, though often temporary, treatments for obesity and its comorbidities, behavioral interventions addressing healthy dietary and physical activity habits remain a mainstay in the obesity treatment paradigm. Therefore, the issue of weight management must be addressed by both general practitioner and subspecialist alike. In this report, we review select aspects of pediatric obesity and obesity-related management issues because it relates in particular to the field of pediatric gastroenterology and hepatology.

Smartphones have the ability to capture and send images, and their use has become common in the emergency setting for transmitting radiographic images with the intent to consult an off-site specialist. Our objective was to evaluate the reliability of smartphone-based instant messaging applications for the evaluation of various pediatric limb traumas, as compared with the standard method of viewing images of a workstation-based picture archiving and communication system (PACS). X-ray images of 73 representative cases of pediatric limb trauma were captured and transmitted to 5 pediatric orthopedic surgeons by the Whatsapp instant messaging application on an iPhone 6 smartphone. Evaluators were asked to diagnose, classify, and determine the course of treatment for each case over their personal smartphones. Following a 4-week interval, revaluation was conducted using the PACS. Intraobserver agreement was calculated for overall agreement and per fracture site. The overall results indicate "near perfect agreement" between interpretations of the radiographs on smartphones compared with computer-based PACS, with κ of 0.84, 0.82, and 0.89 for diagnosis, classification, and treatment planning, respectively. Looking at the results per fracture site, we also found substantial to near perfect agreement. Smartphone-based instant messaging applications are reliable for evaluation of a wide range of pediatric limb fractures. This method of obtaining an expert opinion from the off-site specialist is immediately accessible and inexpensive, making smartphones a powerful tool for doctors in the emergency department, primary care clinics, or remote medical centers, enabling timely and appropriate treatment for the injured child. This method is not a substitution for evaluation of the images in the standard method over computer-based PACS, which should be performed before final decision-making.

Although innumerable studies have analyzed the multiple aspects of osteoporotic vertebral fractures, no study has focused on the clinical features related to spine pain in patients with recent osteoporotic vertebral compression fractures (VCFs). To determine whether the assessment of pain-related behavior (P-RB) of patients with osteoporotic VCFs of recent onset may allow the fracture to be strongly suspected, or even diagnosed, at physical examination. Pain-related behavior of elderly patients attending an outpatient spine clinic was evaluated on the basis of six consecutive movements made on the examining table. Fifty-six patients complaining only of lumbar or thoracic pain. The fractured patients (FPs), representing the fracture group (FG), were the 19 who had a recent VCF, whereas the control group (CG) consisted of the remaining 37 patients. Assessment of P-RB was based on six parameters: grimacing, sighing, clenching or blocking eyelids, gaping or strongly tightening the lips, need for help to take positions, and extreme difficulty to turn in the prone position. A score of 1 or a decimal was assigned to each parameter, the final score to each patient being 0 to 6. Three types of injury, acute (I), subacute (II), or chronic (III), were identified on the basis of the time elapsed from the probable occurrence of the fracture. The diagnosis of recent fracture was based on magnetic resonance images. Patients were videotaped during their movements. An examiner, unaware of the clinical history and diagnosis, gave a P-RB score to all patients and indicated whether they had to be placed in FG or CG, and also their presumable type of fracture. Subsequently, a DVD with the videotapes of all patients was given to three independent examiners, not specifically expert of spine conditions, who were asked to make the same evaluations as the first examiner. The mean scores for P-RB given by the first examiner were 4.6 to FG and 0.7 to CG (pPain-related behavior evaluation of

The author has identified the following significant results. All Skylab 2 imagery received to date has been analyzed manually and data related to fracture analysis and mined land inventories has been summarized on map-overlays. A comparison of the relative utility of the Skylab image products for fracture detection, soil tone/vegetation contrast mapping, and mined land mapping has been completed. Numerous fracture traces were detected on both color and black and white transparencies. Unique fracture trace data which will contribute to the investigator's mining hazards analysis were noted on the EREP imagery; these data could not be detected on ERTS-1 imagery or high altitude aircraft color infrared photography. Stream segments controlled by fractures or joint systems could be identified in more detail than with ERTS-1 imagery of comparable scale. ERTS-1 mine hazards products will be modified to demonstrate the value of this additional data. Skylab images were used successfully to update a mined land map of Indiana made in 1972. Changes in mined area as small as two acres can be identified. As the Energy Crisis increases the demand for coal, such demonstrations of the application of Skylab data to coal resources will take on new importance.

Orthobiologics are biological substances that allow injured muscles, tendons, ligaments, and bone to heal more quickly. They are found naturally in the body; at higher concentrations they can aid in the healing process. These substances include autograft bone, allograft bone, demineralized bone matrix, bone morphogenic proteins, growth factors, stem cells, plasma-rich protein, and ceramic grafts. Their use in sports medicine has exploded in efforts to increase graft incorporation, stimulate healing, and get athletes back to sport with problems including anterior cruciate ligament ruptures, tendon ruptures, cartilage injuries, and fractures. This article reviews orthobiologics and their applications in pediatric sports medicine. Copyright © 2017 Elsevier Inc. All rights reserved.

Lumbar posterior apophyseal ring fracture is an uncommon finding in children, but lumbar spondylolysis is a common disorder. Both disorders are prevalent in young athletes. We describe 3 adolescent athletes who showed both lumbar spondylolysis and lumbar posterior apophyseal ring fracture. Because lumbar spondylolysis is comparatively easy to diagnose, a concurrent posterior lumbar apophyseal ring fracture is likely to be overlooked. In patients with severe low back and radicular pain in whom spondylolysis is suspected, it is important to perform not only magnetic resonance imaging and radiography but also computed tomography for identifying posterior apophyseal ring fractures.

The optimization of the risk- benefit ratio is a major concern in the pediatric radiology, due to the greater vulnerability of children to the late somatic effects and genetic effects of exposure to radiation compared to adults. In Brazil, it is estimated that the causes of death from head trauma are 18 % for the age group between 1-5 years and the radiograph is the primary diagnostic test for the detection of skull fracture . Knowing that the image quality is essential to ensure the identification of structures anatomical and minimizing errors diagnostic interpretation, this paper proposed the development and construction of homogeneous phantoms skull, for the age group 1-5 years. The construction of the phantoms homogeneous was performed using the classification and quantification of tissue present in the skull of pediatric patients. In this procedure computational algorithms were used, using Matlab, to quantify distinct biological tissues present in the anatomical regions studied , using pictures retrospective CT scans. Preliminary data obtained from measurements show that between the ages of 1-5 years, assuming an average anteroposterior diameter of the pediatric skull region of the 145.73 ± 2.97 mm, can be represented by 92.34 mm ± 5.22 of lucite and 1.75 ± 0:21 mm of aluminum plates of a provision of PEP (Pacient equivalent phantom). After its construction, the phantoms will be used for image and dose optimization in pediatric protocols process to examinations of computerized radiography

Relating Cohesive Zone Model to Linear Elastic Fracture Mechanics

Science.gov (United States)

Wang, John T.

2010-01-01

The conditions required for a cohesive zone model (CZM) to predict a failure load of a cracked structure similar to that obtained by a linear elastic fracture mechanics (LEFM) analysis are investigated in this paper. This study clarifies why many different phenomenological cohesive laws can produce similar fracture predictions. Analytical results for five cohesive zone models are obtained, using five different cohesive laws that have the same cohesive work rate (CWR-area under the traction-separation curve) but different maximum tractions. The effect of the maximum traction on the predicted cohesive zone length and the remote applied load at fracture is presented. Similar to the small scale yielding condition for an LEFM analysis to be valid. the cohesive zone length also needs to be much smaller than the crack length. This is a necessary condition for a CZM to obtain a fracture prediction equivalent to an LEFM result.

Frequency of intrathoracic injuries in children younger than 3 years with rib fractures.

Research documents that among children admitted to trauma intensive care units the number of rib fractures sustained indicates the child's likelihood of having and severity of intrathoracic injury. This has been misused in court to argue that children with multiple rib fractures who lack intrathoracic injury have abnormal bone fragility rather than inflicted injury. To determine frequency of intrathoracic injuries in children younger than 3 years with rib fractures in cases of child abuse and accidental trauma. We conducted a retrospective review of rib fractures caused by documented abuse or accidents from 2003 to 2010 in children treated at Seattle Children's Hospital and Harborview Medical Center. A senior pediatric radiologist and radiology fellow independently reviewed the imaging. Children with bone demineralization were excluded. Descriptive and simple comparative statistics were used. Seventy-two percent (47/65) of infants and toddlers with rib fractures were abused. Abused children had more rib fractures than accidentally injured children (5.55 vs. 3.11, P = 0.012). However intrathoracic injuries as a whole (55.6% vs. 12.8%, P fractures were equally frequent, but other extrathoracic fractures were more common with abuse (70.2% vs. 16.7%, P rib fractures than accidentally injured peers. This likely reflects different injury mechanics. Lack of intrathoracic injuries in abused children with rib fractures does not imply bone fragility.

As survival rates for pediatric liver transplantation continue to increase, research attention is turning towards long-term functional consequences, with particular interest in whether medical and transplant-related factors are implicated in neurocognitive outcomes. The relative importance of different factors is unclear, due to a lack of methodological uniformity, inclusion of differing primary diagnoses, variable transplant policies, and organ availability in different jurisdictions. This cross-sectional, single-site study sought to address various methodological limitations in the literature and the paucity of studies conducted outside of North America and Western Europe by examining the intellectual and academic outcomes of Australian pediatric liver transplant recipients (N = 40). Participants displayed significantly poorer intellectual and mathematical abilities compared to the normative population. Greater time on the transplant waitlist was a significant predictor of poorer verbal intelligence, working memory, mathematical abilities and reading, but only when considering the subgroup of children with biliary atresia. These findings support reducing the time children wait for a transplant as a priority. This article is protected by copyright. All rights reserved. This article is protected by copyright.

1981-01-01

The influences of a wide range of material properties, i.e. of A533B steel, a silicon nitride ceramic and a Homalite-100 photoelastic polymer, as well as the influences of the specimen sizes on the dynamic fracture response of fracture specimens are presented in this paper. The results of a numerical study show that the dynamic fracture responses of these fracture specimens of proportional dimensions were indistinguishable provided the normalized dynamic fracture toughness versus normalized crack velocity relations of the three materials coincide. The limited results suggest that should the normalized dynamic fracture toughness versus normalized crack velocity relations between prototype and model materials coincide, then dynamic fracture experiments on scaled models can be used to infer the dynamic fracture response of the prototype.

Pathologic fractures occur in 5-10% of pediatric osteosarcoma (OS) cases and have historically been considered a contraindication to limb salvage. Our purpose was to describe the radiographic features of pathologic fracture and examine its impact on local recurrence rates, functional outcomes, and overall survival. We retrospectively analyzed patients at our institution from 1990 to 2015 with pathologic fracture at diagnosis or during neoadjuvant chemotherapy. We selected a control group of 50 OS patients of similar age and gender without pathologic fracture from 1990 to 2015. Functional outcomes were scored using Musculoskeletal Tumor Society criteria. Chi-square test was used for comparative analysis of groups. Thirty-six patients with 37 pathologic fractures form the study cohort. Of patients who received surgery, 18 of 34 patients with fracture underwent amputation compared to 8 of 48 patients in the nonfracture group (P = 0.007). Indications for amputation in fracture patients were tumor size (n = 7), neurovascular involvement (n = 6), and tumor progression during neoadjuvant chemotherapy (n = 5). Only one patient (2.9%) in the fracture group who underwent limb salvage suffered local recurrence. Of patients who received neoadjuvant chemotherapy, 25 of 34 fracture patients showed poor histological response compared to 24 of 47 nonfracture patients (P = 0.044). There was no statistically significant difference in overall survival (P = 0.96). Functional outcomes were significantly lower in fracture patients (median = 17.5) than nonfracture patients (median = 24) (P = 0.023). Radiographic features of pathologic fractures were highly variable in this population. Limb salvage surgery can be performed without increased risk of local recurrence. Patients with pathologic fracture suffer worse functional outcomes but no decrease in overall survival. © 2016 Wiley Periodicals, Inc.

Natural fractures deeply influence subsurface fluid flow, exerting a primary control on resources like aquifers, hydrocarbons and geothermal reservoirs, and on environmental issues like CO2 storage and nuclear waste disposal. In layered sedimentary rocks, depositional processes-imprinted rock rheology favours the development of both mechanical anisotropy and heterogeneity on a wide range of scales, and are thus expected to strongly influence location and frequency of fractures. To better constrain the contribution of stratigraphic, sedimentological and petrophysical attributes, we performed a high-resolution, multidisciplinary study on a selected stratigraphic interval of jointed foredeep turbidites in the Miocene Marnoso-arenacea Formation (Northern Apennines, Italy), which are characterised by a great lateral and vertical variability of grain-size and depositional structures. Statistical relationships among field and laboratory data significantly improve when the single facies scale is considered, and, for similar facies recording different evolutionary stages of the parent turbidity currents, we observed a direct correlation between the three-dimensional anisotropies of rock hardness tensors and the normalized fracture frequencies, testifying for the primary sedimentary flow-related control on fracture distributions.

Fracture and Healing of Rock Salt Related to Salt Caverns

In recent years, serious investigations of potential extension of the useful life of older caverns or of the use of abandoned caverns for waste disposal have been of interest to the technical community. All of the potential applications depend upon understanding the reamer in which older caverns and sealing systems can fail. Such an understanding will require a more detailed knowledge of the fracture of salt than has been necessary to date. Fortunately, the knowledge of the fracture and healing of salt has made significant advances in the last decade, and is in a position to yield meaningful insights to older cavern behavior. In particular, micromechanical mechanisms of fracture and the concept of a fracture mechanism map have been essential guides, as has the utilization of continuum damage mechanics. The Multimechanism Deformation Coupled Fracture (MDCF) model, which is summarized extensively in this work was developed specifically to treat both the creep and fracture of salt, and was later extended to incorporate the fracture healing process known to occur in rock salt. Fracture in salt is based on the formation and evolution of microfractures, which may take the form of wing tip cracks, either in the body or the boundary of the grain. This type of crack deforms under shear to produce a strain, and furthermore, the opening of the wing cracks produce volume strain or dilatancy. In the presence of a confining pressure, microcrack formation may be suppressed, as is often the case for triaxial compression tests or natural underground stress situations. However, if the confining pressure is insufficient to suppress fracture, then the fractures will evolve with time to give the characteristic tertiary creep response. Two first order kinetics processes, closure of cracks and healing of cracks, control the healing process. Significantly, volume strain produced by microfractures may lead to changes in the permeability of the salt, which can become a major concern in

Health-related quality of life measurement in pediatric clinical practice: An appraisal and precept for future research and application

2005-05-01

Full Text Available Abstract Health-related quality of life (HRQOL measurement has emerged as an important health outcome in clinical trials, clinical practice improvement strategies, and healthcare services research and evaluation. HRQOL measures are also increasingly proposed for use in clinical practice settings to inform treatment decisions. In settings where HRQOL measures have been utilized with adults, physicians report such measures as useful, some physicians alter their treatment based on patient reports on such instruments, and patients themselves generally feel the instruments to be helpful. However, there is a dearth of studies evaluating the clinical utility of HRQOL measurement in pediatric clinical practice. This paper provides an updated review of the literature and proposes a precept governing the application of pediatric HRQOL measurement in pediatric clinical practice. Utilizing HRQOL measurement in pediatric healthcare settings can facilitate patient-physician communication, improve patient/parent satisfaction, identify hidden morbidities, and assist in clinical decision-making. Demonstrating the utility of pediatric HRQOL measurement in identifying children with the greatest needs, while simultaneously demonstrating the cost advantages of providing timely, targeted interventions to address those needs, may ultimately provide the driving force for incorporating HRQOL measurement in pediatric clinical practice.

Pressurized water reactors (PWRs) are susceptible to certain types of hypothetical accidents that can subject the reactor pressure vessel to severe thermal shock, that is, a rapid cooling of the inner surface of the vessel wall. The thermal-shock loading, coupled with the radiation-induced reduction in the material fracture toughness, introduces the possibility of propagation of preexistent flaws and what at one time were regarded as somewhat unique fracture-oriented conditions. Several postulated reactor accidents have been analyzed to discover flaw behavior trends; seven intermediate-scale thermal-shock experiments with steel cylinders have been conducted; and corresponding materials characterization studies have been performed. Flaw behavior trends and related fracture-mechanics data deduced from these studies are discussed

Patellar Sleeve Fracture With Ossification of the Patellar Tendon.

Damrow, Derek S; Van Valin, Scott E

2017-03-01

Patellar sleeve fractures make up greater than 50% of all patellar fractures. They are essentially only seen in the pediatric population because of the thick periosteum and the distal patellar pole apophysis in this group. These fractures can lead to complications if not treated appropriately and in a timely fashion. Complications of missed or untreated patellar sleeve fractures include patella alta, anterior knee pain, and quadriceps atrophy. These can all result in severe limitations in activity. The authors describe a case of a 16-year-old boy who sustained a patellar sleeve fracture 3 years prior to presentation. On presentation, he had patella alta, diminished strength, 5° of extensor lag, and radiographs that revealed bone formation along the patellar tendon. Despite this, he was able to maintain a high level of activity. This case report explores how the patient could have maintained a high level of activity despite having a patellar sleeve fracture. Also, because of the delayed presentation, the patella was ossified and the quadriceps was retracted, which led to a novel approach to reconstructing his distal extensor mechanism. This approach included a V-Y advancement of the quadriceps tendon and patellar tendon reconstruction using the patient's hamstring tendon (semitendinosus). This technique, combined with physical therapy postoperatively, resulted in his return to varsity high school soccer. To the best of the authors' knowledge, this technique has not been reported for this rare condition. [Orthopedics. 2017; 40(2):e357-e359.]. Copyright 2016, SLACK Incorporated.

The thoracic spine exhibits a unique response to trauma as the result of recognized anatomical and biomechanical differences. Despite this response, clinical studies often group thoracic fractures (T1-T10) with more caudal thoracolumbar injuries. Subsequently, there is a paucity of literature on the functional outcomes of this distinct group of injuries. To describe and identify predictors of health-related quality-of-life outcomes and re-employment status in patients with thoracic fractures who present to a spine injury tertiary referral center. An ambispective cohort study with cross-sectional outcome assessment. A prospectively collected fully relational spine database was searched to identify all adult (>16 years) patients treated with traumatic thoracic (T1-T10) fractures with and without neurologic deficits, treated between 1995 and 2008. The Short-Form-36, Oswestry Disability Index, and Prolo Economic Scale outcome instruments were completed at a minimum follow-up of 12 months. Preoperative and minimum 1-year postinjury X-rays were evaluated. Univariate and multivariate regression analysis was used to identify predictors of outcomes from a range of demographic, injury, treatment, and radiographic variables. One hundred twenty-six patients, age 36±15 years (mean±SD), with 135 fractures were assessed at a mean follow-up of 6 years (range 1-15.5 years). Traffic accidents (45%) and translational injuries (54%) were the most common mechanism and dominant fracture pattern, respectively. Neurologic deficits were frequent-53% had complete (American Spinal Injury Association impairment scale [AIS] A) spinal cord deficits on admission. Operative management was performed in 78%. Patients who sustain thoracic fractures, but escaped significant neurologic injury (AIS D or E on admission) had SF-36 scores that did not differ significantly from population norms at a mean follow-up of 6 years. Eighty-eight percent of this cohort was re-employed. Interestingly, Oswestry

Osteoporotic fracture risk is highly heritable, but genome-wide association studies have explained only a small proportion of the heritability to date. Genetic data may improve prediction of fracture risk in osteopenic subjects and assist early intervention and management. To detect common and rare variants in coding and regulatory regions related to osteoporosis-related traits, and to investigate whether genetic profiling improves the prediction of fracture risk. This cross-sectional study was conducted in three clinical units in Korea. Postmenopausal women with extreme phenotypes (n = 982) were used for the discovery set, and 3895 participants were used for the replication set. We performed targeted resequencing of 198 genes. Genetic risk scores from common variants (GRS-C) and from common and rare variants (GRS-T) were calculated. Nineteen common variants in 17 genes (of the discovered 34 functional variants in 26 genes) and 31 rare variants in five genes (of the discovered 87 functional variants in 15 genes) were associated with one or more osteoporosis-related traits.

Directory of Open Access Journals (Sweden)

Full Text Available Fracture systems have strong influence on the overall mechanical behavior of fractured rock masses due to their relatively lower stiffness and shear strength than those of the rock matrix. Understanding the effects of fracture geometrical distribution, such as length, spacing, persistence and orientation, is important for quantifying the mechanical behavior of fractured rock masses. The relation between fracture geometry and the mechanical characteristics of the fractured rock mass is complicated due to the fact that the fracture geometry and mechanical behaviors of fractured rock mass are strongly dependent on the length scale. In this paper, a comprehensive study was conducted to determine the effects of fracture distribution on the equivalent continuum elastic compliance of fractured rock masses over a wide range of fracture lengths. To account for the stochastic nature of fracture distributions, three different simulation techniques involving Oda's elastic compliance tensor, Monte Carlo simulation (MCS, and suitable probability density functions (PDFs were employed to represent the elastic compliance of fractured rock masses. To yield geologically realistic results, parameters for defining fracture distributions were obtained from different geological fields. The influence of the key fracture parameters and their relations to the overall elastic behavior of the fractured rock mass were studied and discussed. A detailed study was also carried out to investigate the validity of the use of a representative element volume (REV in the equivalent continuum representation of fractured rock masses. A criterion was also proposed to determine the appropriate REV given the fracture distribution of the rock mass.

To evaluate lower extremity strength and alignment among children who underwent submuscular plating (SMP). Subjects who underwent SMP for a length unstable femoral fracture returned for isokinetic strength testing ≥2 years after surgery. Extensor and flexor strength deficits (percent difference) between the operative and nonoperative limbs were evaluated. Radiographic measurements of mechanical alignment [anatomic lateral distal femoral angle (aLDFA)] and qualitative measurements (The Pediatric Outcomes Data Collection Instrument, PODCI) were obtained from all subjects. The upper 97.5% confidence interval approach to establishing clinical equivalency was utilized to compare differences in strength and alignment between the operative and nonoperative limbs. An extensor strength deficit of >19% and an aLDFA discrepancy of >5 degrees were considered to be clinically significant. The average age at surgery of the 10 subjects included in the study was 8.7 years. The hardware was placed an average of 27.9 mm from the distal femoral physis and was removed 6.4 months postsurgery. Among all subjects, the median PODCI scores were ≥97 according to all subscales. There was no significant difference in extension torque between the operative versus nonoperative limbs at 60 degrees/s (P=0.5400), 120 degrees/s (P=0.4214), or 180 degrees/s (P=0.8166). More importantly, extension strength deficits between the operative and nonoperative limbs were not clinically significant at 60 degrees/s [upper 97.5% confidence interval (CI), 10.9%], 120 degrees/s (upper 97.5% CI, 11.0%), or 180 degrees/s (upper 97.5% CI, 10.7%). The difference in aLDFA between the operative and nonoperative limb was less than the predefined clinically significant threshold of 5 degrees for all subjects. SMP achieves satisfactory clinical and functional results. In this series, extensor strength deficits and/or lower extremity malalignment were not clinically meaningful.

Recognizing and reporting vertebral fractures: reducing the risk of future osteoporotic fractures

International Nuclear Information System (INIS)

Lentle, B.C.; Brown, J.P.; Khan, A.

2007-01-01

Given the increasing evidence that vertebral fractures are underdiagnosed and not acted on, Osteoporosis Canada and the Canadian Association of Radiologists initiated a project to develop and publish a set of recommendations to promote and facilitate the diagnosis and reporting of vertebral fractures. The identification of spinal fractures is not uniform. More than 65% of vertebral fractures cause no symptoms. It is also apparent that vertebral fractures are inadequately recognized when the opportunity for diagnosis arises fortuitously. It is to patients' benefit that radiologists report vertebral fractures evident on a chest or other radiograph, no matter how incidental to the immediate clinical indication for the examination. The present recommendations can help to close the gap in care in recognizing and treating vertebral fractures, to prevent future fractures and thus reduce the burden of osteoporosis-related morbidity and mortality, as well as fracture-related costs to the health care system. Several studies indicate that a gap exists in regard to the diagnosis of vertebral fractures and the clinical response following such diagnosis. All recommendations presented here are based on consensus. These recommendations were developed by a multidisciplinary working group under the auspices of the Scientific Advisory Council of Osteoporosis Canada and the Canadian Association of Radiologists. Prevalent vertebral fractures have important clinical implications in terms of future fracture risk. Recognizing and reporting fractures incidental to radiologic examinations done for other reasons has the potential to reduce health care costs by initiating further steps in osteoporosis diagnosis and appropriate therapy. Physicians should be aware of the importance of vertebral fracture diagnosis in assessing future osteoporotic fracture risk. Vertebral fractures incidental to radiologic examinations done for other reasons should be identified and reported. Vertebral fractures

2018-01-01

Medial epicondyle entrapment after an acute fracture dislocation of the elbow is a common finding in the pediatric population, but a rare finding in adults. We present a case of an adult patient diagnosed with a traumatic fracture dislocation of the elbow joint with intra-articular entrapment of the medial epicondyle. After initial evaluation, closed reduction was done. Stability testing after reduction showed an unstable joint; thus, open reduction and internal fixation was decided. PMID:29666736

Purpose of review Pediatric uveitis is relatively uncommon, accounting for only 5–10% of all patients with uveitis. However, owing to high prevalence of complications and devastating outcomes, its lifetime burden can be significant. Recent findings Immunomodulatory therapy has been associated with better outcomes in noninfectious pediatric uveitis. However, effective treatments are limited by medication-related complications, including multiorgan toxicities and systemic side effects. Summary We review the current therapies available to treat pediatric uveitis, discuss novel and future therapies, and provide clinical recommendations utilizing these new agents. The consideration for treatment regimens in noninfectious pediatric uveitis is multifactorial. Understanding past, present, and future technology will aid in treatment of a complex and refractory disease. PMID:23872814

Preliminary Validation of a Parent-Child Relational Framework for Teaching Developmental Assessment to Pediatric Residents.

Science.gov (United States)

Regalado, Michael; Schneiderman, Janet U; Duan, Lei; Ragusa, Gisele

A parent-child relational framework was used as a method to train pediatric residents in basic knowledge and observation skills for the assessment of child development. Components of the training framework and its preliminary validation as an alternative to milestone-based approaches are described. Pediatric residents were trained during a 4-week clinical rotation to use a semistructured interview and observe parent-child behavior during health visits using clinical criteria for historical information and observed behavior that reflect developmental change in the parent-child relationship. Clinical impressions of concern versus no concern for developmental delay were derived from parent-child relational criteria and the physical examination. A chart review yielded 330 preterm infants evaluated using this methodology at 4 and 15 months corrected age who also had standardized developmental testing at 6 and 18 months corrected age. Sensitivities and specificities were computed to examine the validity of the clinical assessment compared with standardized testing. A subset of residents who completed 50 or more assessments during the rotation was timed at the end of 4 weeks. Parent-child behavioral markers elicited from the history and/or observed during the health visit correlated highly with standardized developmental assessment. Sensitivities and specificities were 0.72/0.98 and 0.87/0.96 at 4 to 6 and 15 to 18 months, respectively. Residents completed their assessments parent-child relational framework is a potentially efficient and effective approach to training residents in the clinical knowledge and skills of child development assessment.

Children and adolescents with epilepsy often show higher rates of executive functioning deficits and are at an increased risk of diminished health-related quality of life (HRQOL). The purpose of the current study was to determine the extent to which executive dysfunction predicts HRQOL in youth with epilepsy. Data included parental ratings on the Behavior Rating Inventory of Executive Function (BRIEF) and the Quality of Life in Childhood Epilepsy (QOLCE) questionnaire for 130 children and adolescents with epilepsy (mean age=11years, 6months; SD=3years, 6months). Our results identified executive dysfunction in nearly half of the sample (49%). Moderate-to-large correlations were identified between the BRIEF and the QOLCE subscales of well-being, cognition, and behavior. The working memory subscale on the BRIEF emerged as the sole significant predictor of HRQOL. These results underscore the significant role of executive function in pediatric epilepsy. Proactive screening for executive dysfunction to identify those at risk of poor HRQOL is merited, and these results bring to question the potential role of behavioral interventions to improve HRQOL in pediatric epilepsy by specifically treating and/or accommodating for executive deficits.

Distinct Element Method modelling of fold-related fractures in a multilayer sequence

Kaserer, Klemens; Schöpfer, Martin P. J.; Grasemann, Bernhard

2017-04-01

Natural fractures have a significant impact on the performance of hydrocarbon systems/reservoirs. In a multilayer sequence, both the fracture density within the individual layers and the type of fracture intersection with bedding contacts are key parameters controlling fluid pathways. In the present study the influence of layer stacking and interlayer friction on fracture density and connectivity within a folded sequence is systematically investigated using 2D Distinct Element Method modelling. Our numerical approach permits forward modelling of both fracture nucleation/propagation/arrest and (contemporaneous) frictional slip along bedding planes in a robust and mechanically sound manner. Folding of the multilayer sequence is achieved by enforcing constant curvature folding by means of a velocity boundary condition at the model base, while a constant overburden pressure is maintained at the model top. The modelling reveals that with high bedding plane friction the multilayer stack behaves mechanically as a single layer so that the neutral surface develops in centre of the sequence and fracture spacing is controlled by the total thickness of the folded sequence. In contrast, low bedding plane friction leads to decoupling of the individual layers (flexural slip folding) so that a neutral surface develops in the centre of each layer and fracture spacing is controlled by the thickness of the individual layers. The low interfacial friction models illustrate that stepping of fractures across bedding planes is a common process, which can however have two contrasting origins: The mechanical properties of the interface cause fracture stepping during fracture propagation. Originally through-going fractures are later offset by interfacial slip during folding. A combination of these two different origins may lead to (apparently) inconsistent fracture offsets across bedding planes within a flexural slip fold.

One hundred fifty-three men, age 48-96, 86% white, had resided in this Nursing Home for an average of 6.3 years (range 1.3-36) as of August 1984. At that time, we reviewed their medical charts to record the numbers and sites of fractures which had been diagnosed during the preceding 1 to 5 years of Nursing Home residence, the duration of this period depending on the duration of institutionalization. In addition, a clinical database was compiled comprising 70 attributes, including diagnoses, drugs, plasma (serum) chemistries, and measures of hematologic, nutritional, and functional status. Fractures during the studied period of Nursing Home residence had occurred in 24 of 153 men; six residents had experienced two or more fractures. Fracture rates in hip, spine, and wrist were 2564, 366, and 549 per 100,000 patient years, respectively. The total fracture rate, hip fracture rate, and limb fracture rate were five to 11 times higher than in the age-matched general population of white men in the United States; in Rochester, MN; in Dundee, England; in Oxford, England; or in Finland. Univariate statistical analysis showed that the rates for hip fracture or for fracture at any site were significantly associated with 13 attributes: directly with age, plasma somatomedin C, blood urea N, serum creatinine, serum uric acid, serum 25-hydroxyvitamin D (25-OH-D), degree of functional impairment, and chronic urinary tract infection, and inversely with serum 1,25-dihydroxyvitamin D [1,25-(OH)2-D], serum albumin, hematocrit, and hemoglobin. There was not a significant correlation with the number of falls/month which occurred during the 7 months after August 1984. After the effect of age was partialed out, somatomedin C, 25-OH-D, 1,25-(OH)2-D, and the diagnosis of urinary tract infection were still significantly related to the occurrence of fractures. The fact that Nursing Home fracture cases had significantly higher blood urea nitrogen and 25-OH-D, and significantly lower 1,25-(OH)2

Understanding the dose-exposure-response relationship across the pediatric age spectrum from preterm and term newborns to infants, children, adolescents, and adults is a major challenge for clinicians, pharmaceutical companies, and regulatory agencies. Over the past 3 decades, clinical investigations of many drugs commonly used in pediatric therapeutics have provided valuable insights into age-associated differences in drug disposition and action. However, our understanding of the contribution of genetic variation to variability in drug disposition and response in children generally has lagged behind that of adults. This article proposes a systematic approach that can be used to assess the relative contributions of ontogeny and genetic variation for a given compound. Application of the strategy is illustrated using the current regulatory dilemma posed by the safety and effectiveness of over-the-counter cough and cold remedies as an example. The results of the analysis can be used to aid in the design of studies to yield maximally informative data in pediatric populations of different ages and developmental stages and thereby improve the efficiency of study design.

Full Text Available Purpose: To evaluate the association between the development of extremity fracture and visual impairment in adults. Material and Method: This study included 56 patients (patient group aged 18 years or older who had extremity fractures due to a fall. The control group (n=42 was selected from visitors who had regular medical check-ups at our hospital. Each participant underwent a full ophthalmologic examination. Mean age was compared by Student’s t test. The other variables were compared by chi-square test. Results: The prevalence of subjects with visual impairment was significantly higher in the patients group (78.6% than in the control group (38.1% (p<0.05. The prevalence of treatable eye diseases such as cataract and refractive errors were significantly higher in the patient group than in the control group (p<0.05 for both. Twenty-eight patients (50% in the patient group and 8 subjects in the control group had visual acuities lower than 0.5 (p<0.05. Discussion: We have found that the prevalence of visual impairment was significantly higher in adults with extremity fractures due to falls than in the control group. Hence, we believe that regular ophthalmological examination in adults, providing regular use of eyeglasses in patients with refractive errors, and timely treatment of treatable eye diseases such as cataract could decrease the extremity fractures from falls in adults.

We evaluated the utility of MR imaging in pediatric patients with acute and subacute spinal cord injuries. MR imaging of 22 pediatric patients with suspected traumatic spinal cord injuries was reviewed. MR findings were correlated with physical examination and compared to available radiographs and CT examinations performed at time of presentation. Twelve patients had abnormalities on MR imaging. Seven had spinal cord contusions; five contusions were hemorrhagic. Five of seven patients with cord contusion had normal radiographs and CT exams. Six patients with normal radiographs and CT examinations had abnormal MR studies revealing cord contusion, ligamentous injury, disc herniation, and epidural hematoma. MR is useful in initial evaluation of pediatric patients with spinal cord injuries and in prognosis of future neurologic function. In the setting of spinal cord symptomatology and negative radiographic studies, MR imaging should be performed. Surgically correctable causes of cord compression demonstrated by MR imaging include disc herniation, epidural hematoma, and retropulsed fracture fragments. The entity of spinal cord injury without radiographic abnormality is a diagnosis of exclusion which should only be made after radiologic investigation with radiographs, high-resolution thin-section CT, and MR imaging.

We sought to survey emergency physicians in the United States regarding the management of pediatric dehydration secondary to acute gastroenteritis. We hypothesized that responses from physicians with dedicated pediatric training (PT), that is, board certification in pediatrics or pediatric emergency medicine, would differ from responses of physicians with no dedicated pediatric training (non-PT). An anonymous survey was mailed to randomly selected members of the American College of Emergency Physicians and sent electronically to enrollees of Brown University pediatric emergency medicine listserv. The survey consisted of 17 multiple-choice questions based on a clinical scenario depicting a 2-year-old with acute gastroenteritis and moderate dehydration. Questions asked related to treatment preferences, practice setting, and training information. One thousand sixty-nine surveys were received: 997 surveys were used for data analysis, including 269 PT physicians and 721 non-PT physicians. Seventy-nine percent of PT physicians correctly classified the scenario patient as moderately dehydrated versus 71% of non-PT physicians (P = 0.063). Among those who correctly classified the patient, 121 PT physicians (58%) and 350 non-PT physicians (68%) would initially hydrate the patient with intravenous fluids. Pediatrics-trained physicians were more likely to initially choose oral or nasogastric hydration compared with non-PT physicians (P = 0.0127). Pediatrics-trained physicians were less likely to perform laboratory testing compared with the non-PT group (n = 92, 45%, vs n = 337, 66%; P dehydrated children, significantly more PT physicians, compared with non-PT physicians, follow established guidelines.

2008-01-01

Full Text Available Background: The Taylor spatial frame (TSF is a modern multiplanar external fixator that combines the ease of application and computer accuracy in the reduction of fractures. A retrospective review of our prospective TSF database for the use of this device for treating open tibial fractures in pediatric, adolescent, and adult patients was carried out to determine the effectiveness and complications of TSF in the treatment of these fractures. Materials and Methods: Nineteen male patients with open tibial fractures were included. Of these fractures, 10 were Gustilo Type II, five were Gustilo Type IIIA (two had delayed primary closure and three had split thickness skin grafting, and four were Gustilo Type IIIB (all had rotational flaps. Twelve of our patients presented immediately to the emergency room, and the remaining seven cases presented at a mean of 3 months (range, 2.2-4.5 months after the initial injury. The fractures were located in proximal third (n=1, proximal/middle junction (n=2, middle third (n=3, middle/distal junction (n=8, distal third (n=3, and segmental fractures (n=2. Patients were of an average age of 26 years (range, 6-45years. Mean duration of follow-up was 3.5 years. Results: All fractures healed over a mean of 25 weeks (range, 9-46 weeks. All were able to participate in the activities of daily living without any difficulty and most were involved in sports during the last follow-up. Postoperative complications included pin tract infection in 12 patients. Conclusion: The TSF is an effective definitive method of open tibial fracture care with the advantage of early mobilization, ease of soft tissue management through gradual fracture reduction, and the ability to postoperatively manipulate the fracture into excellent alignment.

Infants, children, and adolescents are at increased risk for heat-related illness due to their inability to remove themselves from dangerous environments. Evidence shows that morbidity and mortality from heat illness is related to the length of time core temperature is elevated, so rapid reduction and accurate serial measurements are crucial to prevention of organ system damage and death. The primary methods of patient cooling are conduction (ice-water immersion, cold packs) and convection (moisture and moving air). The choice of method used may depend on availability of equipment, but there is evidence that can guide optimal use of resources. This issue presents evidence-based recommendations and best practices in heat-illness resuscitation, including managing children who are obese, have special needs or take medications, and advocacy for prevention strategies.

2012-02-01

Full Text Available Abstract Introduction Although elbow fractures have a high incidence in the pediatric population, fractures of the capitellum are almost exclusively observed in individuals older than 12 years of age. Due to their rarity in children, reports with large numbers of cases are lacking in the literature and the surgical treatment options are poorly defined. Case presentation We present the case of an 11-year-old Portuguese girl with a displaced fracture of the capitellum of the right elbow, a typical Hahn-Steinthal or Type 1 fracture, which was followed for one year. The treatment and outcome of this fracture are described. Our patient underwent an open reduction and internal fixation with two cannulated screws. There were no complications and normal elbow function was recovered. Conclusion The authors believe that cannulated screw fixation is a reliable method of treatment for Type 1 capitellar fracture in children because it enables good interfragmentary compression, early mobilization, faster functional elbow recovery and implant removal is rarely necessary.

Determine the relative stiffness of 3 bandage/splint constructs intended for emergency fracture stabilization. Experimental model. A single plane free end deflection model was developed to simulate the forces placed on a bandage/splint construct during stabilization of a complete mid-metacarpal bone fracture. The total deflection of the model in one plane was measured following application of 3 different bandage/splint combinations including a classic, 3 layered Robert Jones Bandage (RJB) with a splint placed on the outside of the bandage (RJB-3), an RJB with splint placed after the first of 3 bandage layers (RJB-1), and a single layer full limb bandage with external splint (SS). Comparisons were made between the deflections of the model with each bandage/splint combinations in an effort to determine the most effective method for field fracture stabilization. Laboratory. No animals were utilized in data collection for this study. Two live horses were utilized during the pilot study. Application of bandage and splint to a model intended to simulate the bending force on a lower forelimb fracture in a horse Deflection was determined by the difference between the height of the model's supported free end before application of a 4.5 kg weight and at the conclusion of the deflection test. There was no significant difference in the amount of deflection between bandage/splint combinations (78 ± 32 mm (RJB-1), 94 ± 44 mm (RJB-3), and 93 ± 33 mm (SS)) CONCLUSIONS: The one-layer bandage with splint was equivalent to either RJB configuration in the mean amount of deflection in the simple model of a fracture. © Veterinary Emergency and Critical Care Society 2015.

Full Text Available Jaume Mora1,21Department of Oncology, 2Developmental Tumor Biology Laboratory, Hospital Sant Joan de Deu, Fundacio Sant Joan de Deu, Barcelona, SpainAbstract: Working together with medical oncologists, the question of whether a Ewing sarcoma in a 25-year-old is a pediatric tumor comes up repeatedly. Like Ewing's, some tumors present characteristically at ages that cross over what has been set as the definition of pediatrics (15 years, 18 years, or 21 years?. Pediatric oncology textbooks, surprisingly, do not address the subject of defining a pediatric tumor. They all begin with an epidemiology chapter defining the types of tumors appearing at distinct stages of childhood, adolescence, and young adulthood. Describing the epidemiology of tumors in relation to age, it becomes clear that the disease is related to the phenomenon of aging. The question, however, remains: is there a biological definition of what pediatric age is? And if so, will tumors occurring during this period of life have anything to do with such biological definition? With the aim of finding an objective definition, the fundamental concepts of what defines "pediatrics" was reviewed and then the major features of tumors arising during development were analyzed. The tumors were explored from the perspective of a host immersed in the normal process of growth and development. This physiological process, from pluripotential and undifferentiated cells, makes possible the differentiation, maturation, organization, and function of tissues, organs, and apparatus. A biological definition of pediatric tumors and the infancy–childhood–puberty classification of developmental tumors according to the infancy–childhood–puberty model of normal human development are proposed.Keywords: growth and development, pediatric tumor, infant, childhood and adolescence, pubertal tumors

2012-12-01

The Aster and GeoEye satellite high-resolution images were used to detect the structures related to the fracturing of the upper crust in the North of Chile. In particular, lineament analysis has been applied to detect the presence of epithermal fluids of low sulfurization associated with the Paleozoic ore deposits. These results have been compared with the location of the minerals altered by the presence of geothermal fluids detected using the spectral libraries. Later, the presence of fractures has been corroborated during recognition of fractures in situ and the geochemical analysis of samples of minerals altered by the presence of fluids. It was shown that the results obtained are relevant for the gold vein detection.

Seismic characteristics of tensile fracture growth induced by hydraulic fracturing

Science.gov (United States)

Eaton, D. W. S.; Van der Baan, M.; Boroumand, N.

2014-12-01

Hydraulic fracturing is a process of injecting high-pressure slurry into a rockmass to enhance its permeability. Variants of this process are used for unconventional oil and gas development, engineered geothermal systems and block-cave mining; similar processes occur within volcanic systems. Opening of hydraulic fractures is well documented by mineback trials and tiltmeter monitoring and is a physical requirement to accommodate the volume of injected fluid. Numerous microseismic monitoring investigations acquired in the audio-frequency band are interpreted to show a prevalence of shear-dominated failure mechanisms surrounding the tensile fracture. Moreover, the radiated seismic energy in the audio-frequency band appears to be a miniscule fraction (<< 1%) of the net injected energy, i.e., the integral of the product of fluid pressure and injection rate. We use a simple penny-shaped crack model as a predictive framework to describe seismic characteristics of tensile opening during hydraulic fracturing. This model provides a useful scaling relation that links seismic moment to effective fluid pressure within the crack. Based on downhole recordings corrected for attenuation, a significant fraction of observed microseismic events are characterized by S/P amplitude ratio < 5. Despite the relatively small aperture of the monitoring arrays, which precludes both full moment-tensor analysis and definitive identification of nodal planes or axes, this ratio provides a strong indication that observed microseismic source mechanisms have a component of tensile failure. In addition, we find some instances of periodic spectral notches that can be explained by an opening/closing failure mechanism, in which fracture propagation outpaces fluid velocity within the crack. Finally, aseismic growth of tensile fractures may be indicative of a scenario in which injected energy is consumed to create new fracture surfaces. Taken together, our observations and modeling provide evidence that

To determine differences in bone geometry, estimates of bone strength, muscle size and bone strength relative to load, in women runners with and without a history of stress fracture. We recruited 32 competitive distance runners aged 18-35, with (SFX, n=16) or without (NSFX, n=16) a history of stress fracture for this case-control study. Peripheral quantitative computed tomography (pQCT) was used to assess volumetric bone mineral density (vBMD, mg/mm 3 ), total (ToA) and cortical (CtA) bone areas (mm 2 ), and estimated compressive bone strength (bone strength index; BSI, mg/mm 4 ) at the distal tibia. ToA, CtA, cortical vBMD, and estimated strength (section modulus; Zp, mm 3 and strength strain index; SSIp, mm 3 ) were measured at six cortical sites along the tibia. Mean active peak vertical (pkZ) ground reaction forces (GRFs), assessed from a fatigue run on an instrumented treadmill, were used in conjunction with pQCT measurements to estimate bone strength relative to load (mm 2 /N∗kg -1 ) at all cortical sites. SSIp and Zp were 9-11% lower in the SFX group at mid-shaft of the tibia, while ToA and vBMD did not differ between groups at any measurement site. The SFX group had 11-17% lower bone strength relative to mean pkZ GRFs (phistory of stress fracture. Bone strength relative to load is also lower in this same region suggesting that strength deficits in the middle 1/3 of the tibia and altered gait biomechanics may predispose an individual to stress fracture.

The purpose was to evaluate the prevalence and location of simultaneous fracture using bone scans in patients with hip fracture and to determine the risk factors associated with simultaneous fracture. One hundred eighty two patients with hip fracture were reviewed for this study. Clinical parameters and bone mineral density (BMD) of the lumbar vertebra and femoral neck were investigated. To identify acute simultaneous fracture, a bone scan was performed at 15.4±4.1days after hip fracture. The prevalence and location of simultaneous fracture were evaluated, and multivariate logistic regression analysis was performed to determine the risk factors. Simultaneous fracture was observed in 102 of 182 patients, a prevalence of 56.0%. Rib fracture was the most common type of simultaneous fracture followed by rib with vertebral fracture. The BMD of the lumbar vertebra was significantly lower in patients with simultaneous fracture (p=0.044) and was identified as an independent risk factor (odds ratio: OR 0.05, 95% confidence interval: CI 0.01-0.57). The prevalence of simultaneous fracture was relatively high among patients with hip fracture, and BMD was significantly lower in patients with simultaneous fracture than in patients without it. Surgeons should be aware of the possibility of simultaneous fracture in patients with hip fracture. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available The purpose of this case report was to present the multidisciplinary management of a subgingival crown-root fracture of a patient undergoing apexification treatment. A 12-year-old male patient was referred to the pediatric dentistry clinic with an extensive tooth fracture of the right permanent maxillary lateral incisor. Clinical and radiographic examinations revealed the presence of a complicated crown-root fracture, which had elongated to the buccal subgingival area. The dental history disclosed that the apexification procedure had been started to be performed after his first trauma experience and he had neglected his appointment. The coronal fragment was gently extracted; endodontic treatment was performed; flap surgery was performed to make the fracture line visible. The coronal fragment was reattached to the root fragment with a dual-cure luting composite. A fiber post was stabilized and the access cavity of the tooth was restored with composite resin. At the end of the 24th month, the tooth was asymptomatic, functionally, esthetically acceptable and had no periapical pathology. It is important for the patients undergoing apexification treatment to keep their appointments because of the fracture risk. Restoration of the fractured tooth by preparing retention grooves and a bonding fiber-reinforced post are effective and necessary approaches for successful management.

Fractures and fracture infillings of the Eye-Dashwa Lakes pluton, Atikokan, Ontario

Fractures in the Eye-Dashwa pluton near Atikokan, Ontario can be subdivided on the basis of their filling materials. These materials include aplite, epidote, chlorite, and gypsum-carbonate-clay, listed in order of decreasing age established from crosscutting relations. Textues indicate that infilling occurred during fracture growth. Continuous cooling of the pluton during fracturing is inferred from the expected crystallization temperatures of fillings. Fracturing began before the pluton was completely solidified (650-600 0 C) and continued to temperatures below 100 0 C. Many fractures appear to have been sealed by the filling materials after initiation but were subsequently sheared and filled by lower temperatue materials. Apparently the majority of fractures formed during or immediately after pluton solidification and new fractures became smaller and more restricted in location as cooling progressed. Fractures and filling materials are seen as important features in assessing the possibility of movement of radionuclides in aqueous solutions away from a nuclear fuel waste repository

Full Text Available Background Our pilot study carried out at two Polish pediatric hospital departments revealed that conflicts with parents of hospitalized children represent the main concern of pediatric nurses. The aim of this study was to examine factors determining the conflict solving competence in pediatric nurses in order to develop effective communication training programs for pediatric ward staff. Participants and procedure A total of 78 pediatric nurses completed measures of occupational and perceived stress, conflict modes and competence in solving conflicts with parents of hospitalized children. Results The key factor influencing conflict solving competence was the level of perceived stress and supervisor support. Conclusions Systemic supervised activities aimed at reducing the level of stress, e.g. Balint groups or reflective supervision, could be helpful in mastering the conflict solving competences. Also a paradigm shift from the individual patient to his/her family considered as a patient could potentially improve nurse-parent relations.

This study describes the epidemiology of pediatric volleyball-related injuries treated in US hospital emergency departments. Data for children younger than 18 years obtained from the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission from 1990 through 2009 were analyzed. An estimated 692 024 volleyball-related injuries to children younger than 18 years occurred during the study period. The annual number of injuries declined significantly by 23% during the study period; however, the annual injury rate remained unchanged, and the number of volleyball-related concussions/closed head injuries increased significantly. Upper (48%) and lower (39%) extremity injuries occurred most frequently, as did strains/sprains (54%). Contact with the net/pole was associated with concussions/closed head injury our findings indicate opportunities for making volleyball an even safer sport for children. Protective padding, complying with US volleyball standards, should cover all volleyball poles and protruding hardware to prevent impact-related injuries.

Are bi-axial proximal sesamoid bone fractures in the British Thoroughbred racehorse a bone fatigue related fracture? A histological study.

2010-01-01

To investigate whether microfractures and alterations in the trabecular bone area are associated with catastrophic bi-axial proximal sesamoid bone fractures (PSBF). Proximal sesamoid bones (PSB) from 10 racehorses with PSBF and from 10 control racehorses without musculoskeletal injury were examined using the bulk basic fuchsin method. Bone histomorphometric and microfracture analysis was performed, and cases and controls compared using two-sample t-test, paired t-test, and Mann-Whitney U test. There was no significant difference in the microfracture density and the trabecular bone area between bones from case and control horses, and between fractured and non-fractured bones in case horses. Microfracture density was low in the areas of the PSB examined. Microfracture density was not significantly different between groups, indicating that propagation of micro-cracks is an unlikely predisposing pathologic alteration in PSBF in British racehorses. There was no significant difference in the bone surface area between groups, which one would expect if modelling, adaptation and an increase in bone density were associated with PSBF fracture in the case horses. Therefore, PSBF in the British racehorse does not appear to be associated with microfractures of the trabecular bone of the PSB. The PSB fractures might represent an acute monotonic fracture; however, the aetiology of the fractures remains unknown with additional research required.

Pediatric Melanoma and Drug Development

Full Text Available Importance—Pediatric melanoma occurs, albeit rarely. Should patients be treated by today’s medical standards, or be subjected to medically unnecessary clinical studies? Observations—We identified international, industry-sponsored pediatric melanoma studies triggered by regulatory demands in www.clinicaltrials.gov and further pediatric melanoma studies demanded by European Union pediatric investigation plans. We retrieved related regulatory documents from the internet. We analyzed these studies for rationale and medical beneficence on the basis of physiology, pediatric clinical pharmacology and rationale. Regulatory authorities define children by chronological age, not physiologically. Newborns’ organs are immature but they develop and mature rapidly. Separate proof of efficacy in underage patients is justified formally/regulatorily but lacks medical sense. Children—especially post-puberty—and adults vis-a-vis medications are physiologically very similar. Two adolescent melanoma studies were terminated in 2016 because of waning recruitment, while five studies in pediatric melanoma and other solid tumors, triggered by European Union pediatric investigation plans, continue recruiting worldwide. Conclusions and Relevance—Regulatory-demanded pediatric melanoma studies are medically superfluous. Melanoma patients of all ages should be treated with effective combination treatment. Babies need special attention. Children need dose-finding and pharmacokinetic studies but adolescents metabolize and respond to drugs similarly to adults. Institutional Review Boards/ethics committees should suspend ongoing questionable pediatric melanoma studies and reject newly submitted questionable studies.

Assessing the fracture strength of geological and related materials via an atomistically based J-integral

Jones, R. E.; Criscenti, L. J.; Rimsza, J.

Predicting fracture initiation and propagation in low-permeability geomaterials is a critical yet un- solved problem crucial to assessing shale caprocks at carbon dioxide sequestration sites, and controlling fracturing for gas and oil extraction. Experiments indicate that chemical reactions at fluid-geomaterial interfaces play a major role in subcritical crack growth by weakening the material and altering crack nu- cleation and growth rates. Engineering the subsurface fracture environment, however, has been hindered by a lack of understanding of the mechanisms relating chemical environment to mechanical outcome, and a lack of capability directly linking atomistic insight to macroscale observables. We have developed a fundamental atomic-level understanding of the chemical-mechanical mecha- nisms that control subcritical cracks through coarse-graining data from reactive molecular simulations. Previous studies of fracture at the atomic level have typically been limited to producing stress-strain curves, quantifying either the system-level stress or energy at which fracture propagation occurs. As such, these curves are neither characteristic of nor insightful regarding fracture features local to the crack tip. In contrast, configurational forces, such as the J-integral, are specific to the crack in that they measure the energy available to move the crack and truly quantify fracture resistance. By development and use of field estimators consistent with the continuum conservation properties we are able to connect the data produced by atomistic simulation to the continuum-level theory of fracture mechanics and thus inform engineering decisions. In order to trust this connection we have performed theoretical consistency tests and validation with experimental data. Although we have targeted geomaterials, this capability can have direct impact on other unsolved technological problems such as predicting the corrosion and embrittlement of metals and ceramics.

2005-11-01

The purpose of this study is to evaluate hip fracture risk in relation to fall direction, and to elucidate factors that influence the impact force in falls on the hip. Eight healthy volunteers performed deliberate falls in three directions (lateral, posterolateral and posterior) on a force platform covered by a mattress of 13 cm thickness. Fall descent motions and impact postures were examined by a three-dimensional analyzer. The maximum ground force reaction, velocity of the greater trochanter at impact, and activity of quadriceps and gluteus medius were measured. In all trials of lateral and posterolateral falls, but not of posterior falls, the subjects hit their greater trochanter directly on the mattress. The impact forces were between 2,000 N and 4,000 N. Posterolateral falls showed significantly higher velocity at impact than did posterior falls. The height and the lower limb length exhibited positive correlations with the impact force in all directions of fall. In the lateral fall, there was a positive correlation between the activity of quadriceps and the impact force. In view of the impact point, force, and velocity, the posterolateral fall seemed to carry the highest risk of hip fracture.

Diaphyseal forearm fractures are very common pediatric traumas. At present, distal radius metaphyseal fractures are often successfully treated with closed reduction by emergency physicians. However, the management of diaphyseal fractures remains controversial. The purpose of this study was to analyze the results of diaphyseal forearm fractures in the emergency department (ED) in children. In a prospective 2-year-study, all closed diaphyseal forearm fractures in patients under 15, with an angle of >15° and treated by closed reduction in the ED were included. Fractures with overlapping fragments were excluded. Reduction was performed by an emergency physician, with a standardized analgesic protocol (painkillers and nitrous oxide). Clinical tolerance was checked within the first 24hours, and the radiographic stability of reduction was assessed at days 8 and 15. Initial and final follow-up radiographs were analyzed. Elbow and wrist range of motion was assessed at the final follow-up. Sixty patients (41 boys and 19 girls) were included. Mean age was 5.2 years old (±3). At initial evaluation, the maximum angle was 30° (±11.3). After reduction, the maximum angle was significantly reduced (30° vs. 5°, P<0.001). Mean immobilization in a cast was 11.7 weeks (±2). There were no cast related complications in any of these children. There was no surgery for secondary displacement. Full range of motion was obtained in all patients at the final follow-up. The outcome of conservative treatment of closed diaphyseal forearm fractures, without overlapping fragments was excellent. However, reduction is usually performed in the operating room by orthopedic surgeons under general anesthesia and requires hospitalization, which is very expensive. The results of this study show that high quality care may be obtained in the ED by a trained and experienced team. These results are similar to those for distal metaphyseal fractures, which could extend the indications for reduction in the

Dealing with sub-trochanteric fracture in a child with osteopetrosis : A case report.

Science.gov (United States)

Behera, P; Khurana, A; Saibaba, B; Aggarwal, S

2016-12-01

Osteopetrosis is a rare hereditary condition which may have autosomal recessive or autosomal dominant inheritance. Patients tend to present most commonly with fractures but involvement of cranial nerves and hematopoetic system is not uncommon. Patients with infantile and intermediate type tend to present more often with problems other than orthopaedic problems. While diagnosis can be made on the basis of radiographs, management needs to be customized for every patient. Non operative and operative management both have their advantages and disadvantages. We are here reporting a case of sub-trochanteric fracture in an eight-year-old child which was managed successfully with a dynamic hip screw (DHS). Surgery could be performed successfully by taking precautions during reduction, drilling and screw placement. At the latest follow up, which was after one and half years of surgery, the fracture had united well and the child faced no limitations of activities. Thus, open reduction and fixation with DHS can be considered as an effective management modality for pediatric sub-trochanteric fractures in osteopetrosis.

This case report describes the management of a crown-root fractured maxillary right central incisor and a crown fractured maxillary left central incisor using two different techniques. A complex procedure was designed to manage this case including orthodontic extrusion to move the fracture line above the alveolar bone and surgical recontouring of the altered gingival margin. Finally, the right incisor was restored prosthodontically. Prosthetic treatment was based on performing a post and core, and all-ceramic crown on the extruded tooth. The left, less-damaged incisor was restored directly using composite resin. The treatment resulted in good esthetics and secured periodontal health. This case report demonstrates that a multidisciplinary treatment approach is a reliable and predictable option to save a tooth.

Poór, G; Atkinson, E J; Lewallen, D G; O'Fallon, W M; Melton, L J

1995-01-01

Clinical spectrum, treatment and short-term outcomes were assessed among the 131 Rochester, Minnesota, men who contracted an initial hip fracture due to moderate trauma during 1978-89. Three-fourths of falls leading to hip fracture occurred indoors with little seasonality, and 91% of fractures were in men 65 years of age or older. The ratio of cervical to intertrochanteric femur fractures was 1.4:1, and there was a tendency toward more neurological conditions among the patients with cervical fractures. Hemiarthroplasty and total hip replacement were mostly performed for cervical fractures, while internal fixation was preferred for intertrochanteric fractures. In-hospital mortality was 11.5%, and the 30-day case fatality rate was 16.0%. Age and postoperative deterioration of mental status significantly increased the risk of early death, the latter even after adjustment in a multivariate model, while comorbidity had a suggestive but not statistically significant influence on mortality. More than half the men were discharged to nursing homes, and 79% of the patients who survived at 1 year resided in nursing homes or intermediate care facilities or were attended by home care. Only 41% of survivors recovered their prefracture level of functioning and nearly 60% of patients limped and required a cane or walker. After implementation of the prospective payment system in 1984, the length of hospital stay was reduced, but there was no change in early mortality rates, in the duration of physical therapy following fracture or in attendance at nursing homes. The results of this population-based study demonstrate the strong impact of hip fractures on short-term outcomes in men.

Relative dose efficiencies of antiscatter grids and air gaps in pediatric radiography

McDaniel, D.L.; Cohen, G.; Wagner, L.K.; Robinson, L.H.

1984-01-01

The relative dose efficiencies (RDE) of various antiscatter grids and air gaps were determined for conditions simulating those found in pediatric radiography, using phantoms representing a newborn child, a 5-yr-old and a 10-yr-old child. Our data indicate than an air gap is best for the newborn, due to the low levels of scatter. The 8:1 fiber grid or 15.2-cm air gap without a grid can improve dose efficiency (DE) for the 5-yr-old child by 20%--25% relative to the 3.3-cm air gap and no-grid technique, while for the 10-yr-old child, DE can be improved by 40% with an 8:1 fiber grid

2005-01-01

Objective: To explore the role of endothelin and related cytokines (IL-5, IL-6, IL-8) in the development of bronchial asthma in pediatric patients. Methods: Plasma ET-1 (with RIA) and serum IL-5 (with ELISA), IL-6, IL-8 (with RIA) levels were measured in 42 pediatric patients with bronchial asthma and 30 controls. Results: The plasma ET-1 levels in the patients during acute attack (n=22) were significantly higher than those in patients during remission (n=20) as well as in controls (P 0.05). Levels of ET-1 were positively correlated with those of IL-5 (during attack, r=0.560, P<0.01; during remission, r=0.435, P<0.01). Conclusion: ET and the cytokines IL-5, IL-6, IL-8 participated in the pathogenesis of bronchial asthma through different mechanisms and dynamic determination of which could reflect the progression of the disease.

2013-01-01

Objective: To evaluate 3D CT features of normal anatomy, anatomic variations and fractures of occipital squama. Methods: The 3D CT features on MIP, VR images were analyzed retrospectively in 589 pediatric cases. The normal anatomy, anatomic variations and fractures of occipital squama were observed respectively, and the differential diagnostic features including the individual location, appearance and extension were analyzed. Results: Four hundred and thirty-three patients (75.2%) showed normal anatomy, including 154 patients with adult occipital anatomical features, 279 patients with posterior intraoccipital synchondrosis, and 37 patients with Kerckring-supraoccipital synchondrosis. When cases with recent trauma history were excluded, 113 patients (19.1%) showed anatomic variants, including unpenetrating sutures and penetrating sutures. The former could be subdivided to Mendosal sutures in 23 cases, superior median fissures in 19 cases, and midline supraoccipital fissures in 4 cases, while the latter could be subdivided to the interparietal bone variations in 54 cases, wormian bones in 23 cases, and accessory bones in 7 cases. Two or more variations coexisted in 33 cases. The occipital squama fractures were shown in 34 cases (5.6%), including linear fractures in 27 cases, comminuted fractures in 3 cases, with depression fracture in one case, separation of cranial sutures in 3 cases, and other fractures associated with variants in 3 cases. The fractures were sharp, or jagged, without limitation of the occification. Conclusion: There are different 3D CT features of normal anatomy, anatomic variations and fractures of occipital squama in children, which are important for making the accurate diagnosis. (authors)

Inflammatory bowel disease (IBD) is considered to result from interplay between host and intestinal microbiota. While IBD in adults has shown to be associated with marked changes in the intestinal microbiota, there are only a few studies in children, and particularly studies focusing on therapeutic responses are lacking. Hence, this prospective study addressed the intestinal microbiota in pediatric IBD especially related to the level of inflammation. In total, 68 pediatric patients with IBD and 26 controls provided stool and blood samples in a tertiary care hospital and 32 received anti-tumor necrosis factor-α (anti-TNF-α). Blood inflammatory markers and fecal calprotectin levels were determined. The intestinal microbiota was characterized by phylogenetic microarray and qPCR analysis. The microbiota varied along a gradient of increasing intestinal inflammation (indicated by calprotectin levels), which was associated with reduced microbial richness, abundance of butyrate producers, and relative abundance of Gram-positive bacteria (especially Clostridium clusters IV and XIVa). A significant association between microbiota composition and inflammation was indicated by a set of bacterial groups predicting the calprotectin levels (area under curve (AUC) of 0.85). During the induction of anti-TNF-α, the microbial diversity and similarity to the microbiota of controls increased in the responder group by week 6, but not in the non-responders (PEubacterium rectale and Bifidobacterium spp. predicted the response to anti-TNF-α medication. Intestinal microbiota represents a potential biomarker for correlating the level of inflammation and therapeutic responses to be further validated.

Pediatric obesity & type 2 diabetes.

Dea, Tara L

2011-01-01

This article focuses on (a) identifying obesity and other risk factors for developing type 2 diabetes, (b) differentiating between pediatric type 1 diabetes and type 2 diabetes, and (c) treating pediatric type 2 diabetes. Obesity has significant implications on a child's health, including an increased risk for insulin resistance and progression to type 2 diabetes. Type 2 diabetes in children, characterized by insulin resistance and relative pancreatic b-cell failure due to the increased demand for insulin production, has now reached epidemic proportions. Longitudinal research on pediatric type 2 diabetes, however, is lacking because this epidemic is relatively new. Treatment of type 2 diabetes in children is focused on lifestyle modification with weight management/increased physical activity, and pharmacological management through oral medication or insulin therapy. Because children with type 2 diabetes are at risk for developing diabetes-related complications earlier in life, they need to be closely monitored for comorbidities.

Determining when a fracture occurred: Does the method matter? Analysis of the similarity of three different methods for estimating time since fracture of juvenile long bones.

Science.gov (United States)

Drury, Anne; Cunningham, Craig

2018-01-01

Radiographic fracture date estimation is a critical component of skeletal trauma analysis in the living. Several timetables have been proposed for how the appearance of radiographic features can be interpreted to provide a likely time frame for fracture occurrence. This study compares three such timetables for pediatric fractures, by Islam et al. (2000), Malone et al. (2011), and Prosser et al. (2012), in order to determine whether the fracture date ranges produced by using these methods are in agreement with one another. Fracture date ranges were estimated for 112 long bone fractures in 96 children aged 1-17 years, using the three different timetables. The extent of similarity of the intervals was tested by statistically comparing the overlap between the ranges. Results showed that none of the methods were in perfect agreement with one another. Differences seen included the size of the estimated date range for when a fracture occurred, and the specific dates given for both the upper and lower ends of the fracture date range. There was greater similarity between the ranges produced by Malone et al. (2011) and both the other two studies than there was between Islam et al. (2000) and Prosser et al. (2012). The greatest similarity existed between Malone et al. (2011) and Islam et al. (2000). The extent of differences between methods can vary widely, depending on the fracture analysed. Using one timetable gives an average earliest possible fracture date of less than 2 days before another, but the range was extreme, with one method estimating minimum time since fracture as 25 days before another method for a given fracture. In most cases, one method gave maximum time since fracture as a week less than the other two methods, but range was extreme and some estimates were nearly two months different. The variability in fracture date estimates given by these timetables indicates that caution should be exercised when estimating the timing of a juvenile fracture if relying

2016-11-01

The purpose of this study was to explore health-related quality of life (HRQOL) among Korean patients with osteoporosis and to measure the impact of fractures and comorbidity on their quality of life (QOL) using the Korean National Health and Nutrition Examination Survey (KNHANES) data with a nationwide representativeness. This study was based on 4-year-data obtained from the KNHANES 2008 to 2011. Osteoporosis was diagnosed in 2,078 survey participants according to their bone mineral density measurements using dual energy X-ray absorptiometry. According to the World Health Organization study group, T-scores at or above -1.0 are considered normal, those between -1.0 and -2.5 as osteopenia, and those at or below -2.5 as osteoporosis The EuroQol five-dimensional questionnaire (EQ-5D) index score was used to assess the QOL. Of 2,078 patients diagnosed with osteoporosis, fractures were found to occur at 11.02%. Wrist fracture was the most frequent, affecting 4.52% of the patients, with a significantly different prevalence among men and women ( P <0.001). The overall EQ-5D index score was 0.84±0.01 among patients with osteoporosis. With the exception of cancer, the EQ-5D index score were significantly lower for those having osteoarthritis, rheumatoid arthritis, hypertension, diabetes, chronic obstructive pulmonary disease and cardiovascular events compared to those without the related diseases. We found that low health utility was associated with previous spine fracture and comorbidities in patients with osteoporosis. In particular, the number of fracture experiences greatly deteriorated the HRQOL in patients with osteoporosis. Thus, prevention of secondary fractures and chronic care model for comorbidities should be a priority for osteoporosis management in order to improve HRQOL.

To evaluate the impact of obesity on adverse events and required interventions during pediatric procedural sedation. The Pediatric Sedation Research Consortium database of prospectively collected procedural sedation encounters was queried to identify patients for whom body mass index (BMI) could be calculated. Obesity was defined as BMI ≥95th percentile for age and gender. Sedation-related outcomes, adverse events, and therapeutic interventions were compared between obese and nonobese patients. For analysis, 28,792 records were eligible. A total of 5,153 patients (17.9%) were obese; they were predominantly male and older and had a higher median American Society of Anesthesiologists Physical Status classification (P obese patients (odds ratio [OR] 1.49, 95% confidence interval [1.31, 1.70]). Respiratory events (airway obstruction OR 1.94 [1.54, 2.44], oxygen desaturation OR 1.99 [1.50, 2.63], secretions OR 1.48 [1.01, 2.15], laryngospasm OR 2.30 [1.30, 4.05]), inability to complete the associated procedure (OR 1.96 [1.16, 3.30]), and prolonged recovery (OR 2.66 [1.26, 5.59]) were increased in obese patients. Obese patients more frequently required airway intervention including repositioning, suctioning, jaw thrust, airway adjuncts, and bag-valve-mask ventilation. Multivariate regression analysis demonstrated obesity to be independently associated with minor and moderate but not major adverse events. Obesity is an independent risk factor for adverse respiratory events during procedural sedation and is associated with an increased frequency of airway interventions, suggesting that additional vigilance and expertise are required when sedating these patients. © 2015 John Wiley & Sons Ltd.

The present study was undertaken to evaluate the efficacy of biodegradable plating system for fixation of maxillofacial fractures and to study the morbidity associated with the use of biodegradable plates and screws. This prospective study consisted of 10 patients with maxillofacial fractures requiring open reduction and internal fixation. Fractures with infection, comminuted and pathological fractures were excluded. All were plated with biodegradable system (Inion CPS) using standard plating principles and observed for a total period of 24 weeks. Characteristics of the fractures, ease of use of bioresorbable plate/screw system and post operative complications were assessed. Of total 10 patients, eight patients were of midface fracture and two pediatric patients with mandibular fracture, with nine male and one female. The mean age was 32.8 years. Out of 20 plates and 68 screws applied to the 10 fractures sites; there were three incidences of screw breakage with no other intraoperative difficulties. Paresthesia of the infraorbital nerve was present in two patients, and recovered completely in four weeks after surgery. Fracture reduction was considered to be satisfactory in all cases. One patient developed postsurgical infection and was managed with oral antibiotics and analgesics. Favorable healing can be observed through the use of biodegradable plates and screws to stabilize selected midface fractures in patients of all ages, as well as mandible fractures in early childhood, however further studies with more sample size are required.

This study aimed to develop a tool in identifying traumatized children at low risk of pelvic fracture and to determine the sensitivity of this low-risk model for pelvic fractures. We hypothesized that the proportion of children without predictors with pelvic fracture is less than 1%. This is a retrospective trauma registry analysis of previously healthy children 1 year to 17 years old presenting to the pediatric emergency department with blunt trauma. Postulated predictors of pelvic fracture on radiograph or computed tomography included pain/abnormal examination result of the pelvis/hip, femur deformity, hematuria, abdominal pain/tenderness, Glasgow Coma Scale (GCS) score of 13 or lower, and hemodynamic instability. We used multivariable logistic regression to identify independent predictors of fracture. Of 1,121 eligible patients (mean [SD] age, 8.5 [4.6] years), 87 (7.8%) had pelvic fracture. Independent predictors included pain/abnormal examination result of the pelvis/hip (odds ratio [OR], 16.7; 95% confidence interval [CI], 9.6-29.1), hematuria (OR, 6.6; 95% CI, 3.0-14.6), femoral deformity (OR, 5.9; 95% CI, 3.1-11.3), GCS score of 13 or lower (OR, 2.4; 95% CI, 1.3-4.3), and hemodynamic instability (OR, 3.4; 95% CI, 1.7-6.9). One of 590 children (0.2%; 95% CI, 0-0.5%) without predictors had pelvic fractures versus 86 (16.2%) of 531 in those with one or more predictors (OR, 119; 95% CI, 16.6-833). One of 87 children with pelvic fractures had no predictors (1.1%; 95% CI, 0-3%). When assuming a 100% radiography rate, this tool saves 53% pelvic radiographs. Children with multiple blunt trauma without pain/abnormal examination result of the pelvis/hip, femur deformity, hematuria, abdominal pain/tenderness, GCS score of 13 or lower, or hemodynamic instability constitute a low-risk population for pelvic fracture, with less than 0.5% risk rate. This population does not require routine pelvic imaging. Therapeutic study, level IV.

Frequency of intrathoracic injuries in children younger than 3 years with rib fractures

International Nuclear Information System (INIS)

Research documents that among children admitted to trauma intensive care units the number of rib fractures sustained indicates the child's likelihood of having and severity of intrathoracic injury. This has been misused in court to argue that children with multiple rib fractures who lack intrathoracic injury have abnormal bone fragility rather than inflicted injury. To determine frequency of intrathoracic injuries in children younger than 3 years with rib fractures in cases of child abuse and accidental trauma. We conducted a retrospective review of rib fractures caused by documented abuse or accidents from 2003 to 2010 in children treated at Seattle Children's Hospital and Harborview Medical Center. A senior pediatric radiologist and radiology fellow independently reviewed the imaging. Children with bone demineralization were excluded. Descriptive and simple comparative statistics were used. Seventy-two percent (47/65) of infants and toddlers with rib fractures were abused. Abused children had more rib fractures than accidentally injured children (5.55 vs. 3.11, P = 0.012). However intrathoracic injuries as a whole (55.6% vs. 12.8%, P < 0.001) and individual types of intrathoracic injuries were more common with accidents. Rates of other thoracic cage injuries did not differ substantially (27.8% accidents vs. 12.8% abuse, P = 0.064). Intracranial and intra-abdominal injuries and skull fractures were equally frequent, but other extrathoracic fractures were more common with abuse (70.2% vs. 16.7%, P < 0.001). Abused infants and toddlers have fewer intrathoracic injuries but more rib fractures than accidentally injured peers. This likely reflects different injury mechanics. Lack of intrathoracic injuries in abused children with rib fractures does not imply bone fragility. (orig.)

The pediatric dermatology workforce has not been systematically evaluated since recent changes in board certification requirements. To quantify and characterize the workforce of academic pediatric dermatologists and examine issues related to training, hiring, and retention. Dermatology chairpersons and residency directors in the United States and Canada completed a 30-question survey. Eighty of 132 programs (61%) responded to the survey. More than two thirds of programs (56/80) employed a pediatric dermatologist, and 34 programs were recruiting a pediatric dermatologist. The number of residents that pursue careers in pediatric dermatology is significantly associated with the number of pediatric dermatologists on faculty at their institution. Self-reported data, which may have been reflected by recall bias, and 61% response rate. At a majority of academic centers, the current pool of pediatric dermatology faculty is neither adequate to meet academic nor clinical demands. Methods to increase exposure to pediatric dermatology among medical students and residents must be sought.

Tibial Plateau Fractures

Elsøe, Rasmus

This PhD thesis reported an incidence of tibial plateau fractures of 10.3/100,000/year in a complete Danish regional population. The results reported that patients treated for a lateral tibial plateau fracture with bone tamp reduction and percutaneous screw fixation achieved a satisfactory level...... with only the subgroup Sport significantly below the age matched reference population. The thesis reports a level of health related quality of life (Eq5d) and disability (KOOS) significantly below established reference populations for patients with bicondylar tibial plateau fracture treated with a ring...... fixator, both during treatment and at 19 months following injury. In general, the thesis demonstrates that the treatment of tibial plateau fractures are challenging and that some disabilities following these fractures must be expected. Moreover, the need for further research in the area, both with regard...

Mandibular fractures in children are very rare as compared to adults due to protected anatomic features of child and less exposure to road traffic accidents. Management becomes complicated due to inherent dynamic nature, instability of mixed dentition and fear of surgery. Conservative management can be done with the help of acrylic cap splints along with circum-mandibular wiring, intermaxillary fixation with eyelet wires, arch wires or open reduction and internal fixation with bio-resorbable ...

The purpose of this study was to investigate the long-term clinical and radiologic outcomes of treating dislocated condylar fractures sustained in childhood with open reduction and internal fixation (ORIF). Six children 14 years or younger with a condylar neck or subcondylar fracture with dislocation of the condyle from the glenoid fossa were treated with ORIF. Patients were followed for 27 to 92 months post-ORIF (mean: 67.6 months) with routine clinical and radiologic examinations. On the dislocated side, all patients radiographically showed signs of remodeling of the condylar process and shortening of the ramus. Subsequent to their fractures, 3 patients were classified with Angle class II malocclusion, retrognathism, and deviation of the mandibular symphysis. Four patients had objective and/or subjective signs of temporomandibular (TMJ) dysfunction. Until open surgery demonstrates a consistent functional advantage, nonsurgical management should be considered the first treatment option for the dislocated pediatric condylar fracture.

Pediatric advanced life support and sedation of pediatric dental patients.

Programs provided by the Korea Association of Cardiopulmonary Resuscitation include Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), Pediatric Advanced Life Support (PALS), and Korean Advanced Life Support (KALS). However, programs pertinent to dental care are lacking. Since 2015, related organizations have been attempting to develop a Dental Advanced Life Support (DALS) program, which can meet the needs of the dental environment. Generally, for initial management of emergency situations, basic life support is most important. However, emergencies in young children mostly involve breathing. Therefore, physicians who treat pediatric dental patients should learn PALS. It is necessary for the physician to regularly renew training every two years to be able to immediately implement professional skills in emergency situations. In order to manage emergency situations in the pediatric dental clinic, respiratory support is most important. Therefore, mastering professional PALS, which includes respiratory care and core cases, particularly upper airway obstruction and respiratory depression caused by a respiratory control problem, would be highly desirable for a physician who treats pediatric dental patients. Regular training and renewal training every two years is absolutely necessary to be able to immediately implement professional skills in emergency situations.

Aim of this study is to determine the levels of knowledge related with drug administration and drug administration errors of nurses who care for pediatric patients. The study data were obtained from the nurses who were working in the departments of pediatrics in two education and research hospitals in the province of İstanbul and who accepted to participate in the study. The questionnaire form of the study was established by the investigators in accordance with the experiences and literature information. A total of 31 questions related with drug preparation, calculation and administration together with the general working properties of the individual were filled out by face to face interview. The data were evaluated using percent and chi-square tests. The study was initiated after ethics committee approval was obtained from Şişli Hamidiye Etfal Education and Research Hospital (365/2013). The study was conducted with 98 nurses who accepted the questionnaire. The education levels of the participants were as follows: undergraduate (48%), high school (32.7%), associate degree (12.2%), master's degree (6.1%) and postgraduate (1%). It was found that 88.8% of the participants worked in a patient-centered fashion and 11.2% worked in a work-centered fashion. The frequency of interruption/distraction during preparation of treatment was found to be 92.9%. It was found that the frequency of checking by two people during preparation or administration of high risk drugs was 64.3% and the conditions under which drugs should be kept were found to known correctly with a rate of 76.5%. It was found that undergraduate healthcare workers were more successful in converting units (p= 0.000). It was found that powder weight of drugs was considered with a rate of 85.7% in calculation. Conclusively, it was found that nurses who worked in pediatric wards did not receive a standard education in terms of drug administration and preparation. It was found that undergraduate nurses were more

Transfixation pinning and casting of radial-ulnar fractures in calves: A review of three cases.

We reviewed the medical records of three calves with radial-ulnar fractures which were reduced and stabilized by transfixation pinning and casting. Multiple Steinmann pins were placed transversely through proximal and distal fracture fragments and the pin ends were incorporated in fiberglass cast material after fracture reduction. Cast material was placed from proximal to distal radius and served as an external frame to maintain pin position and fracture reduction.At the time of injury, the calves ranged in age from one day to two months and weighed from 37-102 kg. Two fractures were comminuted and one was transverse. All fractures were closed. After surgery, all calves could walk within 24 hours. Radiographic and clinical evidence of fracture healing was present five to seven weeks (mean 6) after surgery. At that time, the pins and cast material were removed. Return to normal function was rapid and judged to be excellent at follow-up evaluation five to nine months later.Advantages of transfixation pinning and casting in management of radial-ulnar fractures include flexibility in pin positioning, adequate maintenance of reduction, early return to weight-bearing status, preservation of joint mobility, and ease of ambulation. The inability to adjust fixation and alignment after cast application is a disadvantage of this technique compared with other external fixators. We concluded that transfixation pinning is a useful means of stabilizing radial-ulnar fractures in pediatric bovine patients.

The injuries caused by earthquakes are often complex and of various patterns. Our study included all fracture inpatients from the Yushu earthquake (1323 in total), to learn more about the incidence and distribution of fractures during earthquakes. A retrospective study of the clinical characteristics of hospitalized fracture patients after the 2010 Yushu earthquake was conducted from December 20 to 25, 2010.We reviewed medical records of hospitalized patients who had been evacuated from the Yushu earthquake area between April 14 and June 15, 2010, from 57 hospitals, and also reviewed more than 100 documents assembled from daily medical rescue and disease prevention reports submitted by the frontline rescue organizations. In total, 78.0% of fracture patients were admitted to the hospital within 3 days after the earthquake. There were 1323 patients who presented with 1539 fractures. The most common fracture occurred in the lower limbs, followed by spinal, pelvic, and shoulder-upper limb fractures. The end of the thoracic vertebra and the lumbar vertebra were the high-risk sites for vertebral fractures. A total of 38 patients became paraplegic. A 2-level spatial clustering was detected among the 193 patients presenting with 2 fractures. Analysis profiles of the injuries and clinical features of patients with earthquake-related fractures will positively impact rescue efforts and the treatment of fracture injuries caused by possible future natural disasters. We should assemble orthopedic-related medications and surgical equipment, and allocate them promptly after a major earthquake. Copyright © 2016 Elsevier Inc. All rights reserved.
