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.

Skeletal injuries are often strong indicators of child abuse and their detection is therefore crucial. The aim of this study was to compare the sensitivity of three diagnostic approaches, namely autopsy, traditional (conventional) radiology, and computed tomography on "battered" piglets, in order to verify the sensitivity of each method, with respect to the true number of bone fractures assessed once the piglet was skeletonised (osteological control). Four newborn cadaver piglets who had died from natural causes were severely beaten post-mortem in every district of the body. Traditional radiography, computed tomography (CT) and autopsy were performed. The piglet was then macerated until skeletonised and the number of all fractures present recorded (osteological control). On the cranium, traditional radiology revealed only 35% circa of actual fractures, autopsy detected only 31% (P<0.01 for both comparisons versus osteological control), whereas CT imaging detected all fractures actually present. For ribs, radiology detected only 47% of all fractures present, and autopsy 65% circa (P>0.05 for both comparisons versus osteological control), while CT scans detected 34% (P<0.01). In suspected cases of fatal child abuse, we suggest that the bones of specific districts be directly analysed either at autopsy or by collecting specific diagnostic sites, such as parts of the rib cage, and subjecting them to maceration. The removed areas could be replaced with artificial material for cosmetic purposes. The authors stress the importance of combined radiological, CT scan, autopsy and osteological survey in the detection of perimortem bone fractures.

Children with glucocorticoid-treated illnesses are at risk for osteoporotic vertebral fractures and growing awareness has led to increased monitoring for these fractures. However scant literature describes developmental changes in vertebral morphology that can mimic fractures. The goal of this paper is to aid in distinguishing between normal variants and fractures. We illustrate differences using lateral spine radiographs obtained annually from children recruited to the Canada-wide STeroid-Associated Osteoporosis in the Pediatric Population (STOPP) observational study, in which 400 children with glucocorticoid-treated leukemia, rheumatic disorders, and nephrotic syndrome were enrolled near glucocorticoid initiation and followed prospectively for 6 years. Normal variants mimicking fractures exist in all regions of the spine and fall into two groups. The first group comprises variants mimicking pathological vertebral height loss, including not-yet-ossified vertebral apophyses superiorly and inferiorly which can lead to a vertebral shape easily over-interpreted as anterior wedge fracture, physiologic beaking, and spondylolisthesis associated with shortened posterior vertebral height. The second group includes variants mimicking other radiologic signs of fractures: anterior vertebral artery groove resembling an anterior buckle fracture, Cupid’s bow balloon disk morphology, Schmorl nodes mimicking concave endplate fractures, and parallax artifact resembling endplate interruption or biconcavity. If an unexpected vertebral body contour is detected, careful attention to its location, detailed morphology, and (if available) serial changes over time may clarify whether it is a fracture requiring change in management or simply a normal variant. Awareness of the variants described in this paper can improve accuracy in the diagnosis of pediatric vertebral fractures. PMID:25828359

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.

Only a small proportion of all paediatric fractures is caused by child abuse or neglect, especially in highly prevalent long bone fractures. It can be difficult to differentiate abusive fractures from non-abusive fractures. This article focuses on femoral fractures in young children. Based on three cases, this article presents a forensic evidence-based approach to differentiate between accidental and non-accidental causes of femoral fractures. We describe three cases of young children who were presented to the emergency department because of a suspected femur fracture. Although in all cases, the fracture had a similar location and appearance, the clinical history and developmental stage of the child led to three different conclusions. In the first two cases, an accidental mechanism was a plausible conclusion, although in the second case, neglect of parental supervision was the cause for concern. In the third case, a non-accidental injury was diagnosed and appropriate legal prosecution followed. Any doctor treating children should always be aware of the possibility of child abuse and neglect in children with injuries, especially in young and non-mobile children presenting with an unknown trauma mechanism. If a suspicion of child abuse or neglect arises, a thorough diagnostic work-up should be performed, including a full skeletal survey according to the guidelines of the Royal College of Radiologists and the Royal College of Paediatrics and Child Health. In order to make a good assessment, the radiologist reviewing the skeletal survey needs access to all relevant clinical and social information. PMID:26642309

Child abuse or nonaccidental trauma is a major problem worldwide; in Spain, there are about 12,000 victims per year. The detection of specific lesions or findings that are incongruent with the reported mechanism of trauma mean that radiologists are often the physician responsible for sounding the alarm in cases of abuse. The triad consisting of subdural hematoma, metaphyseal fracture, and posterior rib fractures is very characteristic of the battered child syndrome. The finding of acute and chronic lesions in the same patient is highly specific for nonaccidental trauma. Fractures of long bones in patients who have yet begun to walk should also alert to possible child abuse. Lesions that are highly specific for abuse, such as classic metaphyseal fractures or posterior rib fractures, can be difficult to demonstrate radiographically and are usually clinically occult. The American College of Radiology (ACR) protocols recommend obtaining three separate X-rays of each upper and lower limb. It is important to use X-ray systems that give high resolution images with low kilovoltage (50-70 kvp) and appropriate milliamperage. A skeletal survey consisting of a series of images collimated to each body region is recommended for all children under the age of two years in whom abuse is suspected. A follow-up skeletal survey about two weeks after the initial survey is useful for detecting new fractures and for assessing the consolidation of others, which helps in dating the lesions. Head injuries are the leading cause of death in abused children. Although computed tomography is the first neuroimaging technique in nonaccidental trauma, magnetic resonance imaging of the head can better characterize the lesions seen on computed tomography and can help to estimate the age of the lesions.

Emergency department assessment represents a critical but often missed opportunity to identify elder abuse, which is common and has serious consequences. Among emergency care providers, diagnostic radiologists are optimally positioned to raise suspicion for mistreatment when reviewing imaging of geriatric injury victims. However, little literature exists describing relevant injury patterns, and most radiologists currently receive neither formal nor informal training in elder abuse identification. We present 2 cases to begin characterisation of the radiographic findings in elder abuse. Findings from these cases demonstrate similarities to suspicious findings in child abuse including high-energy fractures that are inconsistent with reported mechanisms and the coexistence of acute and chronic injuries. Specific injuries uncommon to accidental injury are also noted, including a distal ulnar diaphyseal fracture. We hope to raise awareness of elder abuse among diagnostic radiologists to encourage future large-scale research, increased focus on chronic osseous findings, and the addition of elder abuse to differential diagnoses.

Summary Osteogenesis imperfecta (OI) is a rare hereditary disease caused by mutations in genes coding for type I collagen, resulting in bone fragility. In literature are described forms lethal in perinatal period, forms which are moderate and slight forms where the only sign of disease is osteopenia. Child abuse is an important social and medical problem. Fractures are the second most common presentation after skin lesions and may present specific patterns. The differential diagnosis between slight-moderate forms of OI and child abuse could be very challenging especially when other signs typical of abuse are absent, since both could present with multiple fractures without reasonable explanations. We report a 20 months-old female with a history of 4 fractures occurred between the age of three and eighteen months, brought to authorities’ attention as a suspected child abuse. However when she came to our department physical examination, biochemical tests, total body X-ray and a molecular analysis of DNA led the diagnosis of OI. Thus, a treatment with bisphosphonate and a physical rehabilitation process, according to Vojta method, were started with improvement in bony mineralization, gross motor skills and absence of new fracture. In conclusion our case demonstrates how in any child presenting fractures efforts should be made to consider, besides child abuse, all the other hypothesis even the rarest as OI. PMID:23289038

ABSTRACT Objective: To increase the level of awareness that Ehlers-Danlos/hypermobility syndrome (EDS) and vitamin D deficiency are associated with infantile fragility fractures and radiologic features that may be mistakenly reported to be caused by non-accidental trauma due to Child Abuse and Neglect (CAN). Patients and Methods: We constructed a case series, the largest to date, of infants with EDS who were vitamin D sufficient, insufficient and deficient and infants without EDS but with documented vitamin D deficiency and radiologic evidence of rickets who presented with multiple fractures originally diagnosed as being non-accidental and caused by child abuse. These infants were referred to the outpatient Bone Health Care Clinic at Boston University Medical Campus over a 6-year (2010–2015) period. We also present 6 index cases in which the court concluded that there was no convincing evidence of child abuse and the infants were returned to their parents. Institutional Review Board (IRB) approval was obtained. Results: We present 72 cases of infants with multiple fractures diagnosed to be caused by non-accidental trauma. All infants were younger than one year of age. Among them, 93%(67) had clinical evidence of EDS and/or a family history with a confirmed clinical diagnosis of at least one parent having EDS and the other 7%(5) without evidence of EDS had vitamin D deficiency/infantile rickets. Three of the EDS infants were diagnosed as osteogenesis imperfecta (OI)/EDS overlap syndrome. The most common fractures noted at diagnosis were ribs and extremity fractures (including classic metaphyseal lesions). Serum levels of 25-hydroxyvitamin D [25(OH)D] were reported in 48 infants (18.0 ± 8.5 ng/ml) and in 30 mothers (21.3 ± 11.7 ng/ml). Sixty-three percent (27) of the EDS infants who had their serum 25(OH)D measured were vitamin D deficient 25(OH)D<20 ng/ml and 5 were vitamin D sufficient 25(OH)D>30 ng/ml. The mean serum level for infants with vitamin D deficiency

Hydraulic fracture propagation modeling and data-based fracture identification

NASA Astrophysics Data System (ADS)

Zhou, Jing

Successful shale gas and tight oil production is enabled by the engineering innovation of horizontal drilling and hydraulic fracturing. Hydraulically induced fractures will most likely deviate from the bi-wing planar pattern and generate complex fracture networks due to mechanical interactions and reservoir heterogeneity, both of which render the conventional fracture simulators insufficient to characterize the fractured reservoir. Moreover, in reservoirs with ultra-low permeability, the natural fractures are widely distributed, which will result in hydraulic fractures branching and merging at the interface and consequently lead to the creation of more complex fracture networks. Thus, developing a reliable hydraulic fracturing simulator, including both mechanical interaction and fluid flow, is critical in maximizing hydrocarbon recovery and optimizing fracture/well design and completion strategy in multistage horizontal wells. A novel fully coupled reservoir flow and geomechanics model based on the dual-lattice system is developed to simulate multiple nonplanar fractures' propagation in both homogeneous and heterogeneous reservoirs with or without pre-existing natural fractures. Initiation, growth, and coalescence of the microcracks will lead to the generation of macroscopic fractures, which is explicitly mimicked by failure and removal of bonds between particles from the discrete element network. This physics-based modeling approach leads to realistic fracture patterns without using the empirical rock failure and fracture propagation criteria required in conventional continuum methods. Based on this model, a sensitivity study is performed to investigate the effects of perforation spacing, in-situ stress anisotropy, rock properties (Young's modulus, Poisson's ratio, and compressive strength), fluid properties, and natural fracture properties on hydraulic fracture propagation. In addition, since reservoirs are buried thousands of feet below the surface, the

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.

To determine rates of skeletal survey completion and injury identification as a function of age among children who underwent subspecialty evaluation for concerns of physical abuse. This was a retrospective secondary analysis of an observational study of 2609 children <60 months of age who underwent evaluation for possible physical abuse. We measured rates of skeletal survey completion and fracture identification for children separated by age into 6-month cohorts. Among 2609 subjects, 2036 (78%) had skeletal survey and 458 (18%) had at least one new fracture identified. For all age groups up to 36 months, skeletal survey was obtained in >50% of subjects, but rates decreased to less than 35% for subjects >36 months. New fracture identification rates for skeletal survey were similar between children 24-36 months of age (10.3%, 95% CI 7.2-14.2) and children 12-24 months of age (12.0%, 95% CI 9.2-15.3) CONCLUSIONS: Skeletal surveys identify new fractures in an important fraction of children referred for subspecialty consultation with concerns of physical abuse. These data support guidelines that consider skeletal survey mandatory for all such children <24 months of age and support a low threshold to obtain skeletal survey in children as old as 36 months.

While various forms of facial trauma, bruising, burns, and fractures are frequently seen in cases of child abuse, purposeful nasal erosion has rarely been identified as a form of abusive injury. Progressive destruction of nasal tissue in children provokes a wide differential diagnosis crossing multiple subspecialties: infectious, primary immunodeficiencies, inflammatory conditions, malignancy, and genetic disorders. Progressive nasal erosion also can be a manifestation of child abuse. The proposed mechanism is repetitive mechanical denudation of the soft tissue and cartilage resulting in chronic inflammation, bleeding, and ultimately destruction of the insulted tissue. We report 6 cases of child abuse manifesting as overt nasal destruction. Copyright © 2018 Elsevier B.V. All rights reserved.

Role of the laboratory in the evaluation of suspected drug abuse.

Despite the high incidence of substance abuse, it remains a common cause of misdiagnosis. In patients who have abused or who are currently abusing drugs, symptoms of a psychiatric illness may be mimicked by either the drug's presence or absence. The laboratory can aid in making a differential diagnosis and eliminating drugs from active consideration as a cause of psychosis, depression, mania, and personality changes. Treatment planning and prevention of serious medical consequences often rest on the accuracy of the admission drug screen. Testing is widely used to assess improvement in substance abuse in both inpatient and outpatient settings. In occupational settings, testing has been used as an early indicator that a problem exists and as a successful prevention tool. The appropriate use of analytic technology in drug abuse testing requires an understanding of available test methodologies. These include drug screens by thin-layer chromatography, comprehensive testing using enzyme immunoassay, and computer-assisted gas chromatography-mass spectrometry (GC-MS). Testing for specific drugs considered likely causes or precipitants of "psychiatric" complaints is available with enzyme assays, radioimmunoassay, or definitive forensic-quality testing using GC-MS.

A false accusation of child abuse has a major impact on child and family. Conversely, a missed diagnosis of child abuse may have significant and lifelong consequences for the child. For health professionals the assessment of the nature of the injury and differentiating between accidental and inflicted injury, disease manifestation or a physiological phenomenon can be challenging. For adequate determination of the cause of injury, an integrated approach including paediatric knowledge and forensic medical expertise is essential. Therefore, a national expertise centre for child abuse (LECK) was established in the Netherlands in 2014. The first results of this integrated approach are described and illustrated with three case reports. Case A, a 7-month-old boy with an accidental humerus fracture. Case B, an 8-year-old boy with a false positive suspicion of child abuse who was eventually diagnosed with Henoch-Schönlein syndrome. Case C, boy of 3 months with bruises and a metaphyseal fracture of the femur, both highly suspected of being inflicted injury.

Management of pediatric mandible fractures.

The pediatric mandible fracture is a rare occurrence when compared with the number of mandible fractures that occur within the adult population. Although the clinician who manages facial fractures may never encounter a pediatric mandible fracture, it is a unique injury that warrants a comprehensive discussion. Because of the unique anatomy, dentition, and growth of the pediatric patient, the management of a pediatric mandible fracture requires true diligence with a variance in treatment ranging from soft diet to open reduction and internal fixation. In addition to the variability in treatment, any trauma to the face of a child requires additional management factors including child abuse issues and long-term sequelae involving skeletal growth, which may affect facial symmetry and occlusion. The following is a review of the incidence, relevant anatomy, clinical and radiographic examination, and treatment modalities for specific fracture types of the pediatric mandible based on the clinical experience at the University of Miami/Jackson Memorial Hospital Oral and Maxillofacial Surgery program. In addition, a review of the literature regarding the management of the pediatric mandible fracture was performed to offer a more comprehensive overview of this unique subset of facial fractures.

Abuse by burning is estimated to occur in 1 to 25% of children admitted with burn injuries annually. Hair and urine toxicology for illicit drug exposure may provide additional confirmatory evidence for abuse. To determine the impact of hair and urine toxicology on the identification of child abuse, we performed a retrospective chart review of all pediatric patients admitted to our burn unit. The medical records of 263 children aged 0 to 16 years of age who were admitted to our burn unit from January 2002 to December 2007 were reviewed. Sixty-five children had suspected abuse. Of those with suspected abuse, 33 were confirmed by the Department of Health and Human Services and comprised the study group. Each of the 33 cases was randomly matched to three pediatric (0-16 years of age) control patients (99). The average annual incidence of abuse in pediatric burn patients was 13.7+/-8.4% of total annual pediatric admissions (range, 0-25.6%). Age younger than 5 years, hot tap water cause, bilateral, and posterior location of injury were significantly associated with nonaccidental burn injury on multivariate analysis. Thirteen (39.4%) abused children had positive ancillary tests. These included four (16%) skeletal surveys positive for fractures and 10 (45%) hair samples positive for drugs of abuse (one patient had a fracture and a positive hair screen). In three (9.1%) patients who were not initially suspected of abuse but later confirmed, positive hair test for illicit drugs was the only indicator of abuse. Nonaccidental injury can be difficult to confirm. Although inconsistent injury history and burn injury pattern remain central to the diagnosis of abuse by burning, hair and urine toxicology offers a further means to facilitate confirmation of abuse.

Bone tumor mimickers: A pictorial essay

Focal lesions in bone are very common and many of these lesions are not bone tumors. These bone tumor mimickers can include numerous normal anatomic variants and non-neoplastic processes. Many of these tumor mimickers can be left alone, while others can be due to a significant disease process. It is important for the radiologist and clinician to be aware of these bone tumor mimickers and understand the characteristic features which allow discrimination between them and true neoplasms in order to avoid unnecessary additional workup. Knowing which lesions to leave alone or which ones require workup can prevent misdiagnosis and reduce patient anxiety. PMID:25114385

Elder abuse is underrecognized, and identification of subtle cases requires a high index of suspicion among all health care providers. Because many geriatric injury victims undergo radiographic imaging, diagnostic radiologists may be well positioned to identify injury patterns suggestive of abuse. Little is known about radiologists' experience with elder abuse. Our goal was to describe knowledge, attitudes, training, and practice experience in elder abuse detection among diagnostic radiologists. We conducted 19 interviews with diagnostic radiologists at a large urban academic medical center using a semistructured format. Data from these sessions were coded and analyzed to identify themes. Only two radiologists reported any formal or informal training in elder abuse detection. All subjects believed they had missed cases of elder abuse. Even experienced radiologists reported never having received a request from a referring physician to assess images for evidence suggestive of elder abuse. All subjects reported a desire for additional elder abuse training. Also, subjects identified radiographic findings or patterns potentially suggestive of elder abuse, including high-energy injuries such as upper rib fractures, injuries in multiple stages of healing, and injuries inconsistent with reported mechanism. Radiologists are uniquely positioned to identify elder abuse. Though training in detection is currently lacking, providers expressed a desire for increased knowledge. In addition, radiologists were able to identify radiographic findings suggestive of elder abuse. On the basis of these findings, we plan to conduct additional studies to define pathognomonic injury patterns and to explore how to empower radiologists to incorporate detection into their practice.

Data from these sessions were coded and analyzed to identify themes. RESULTS Only two radiologists reported any formal or informal training in elder abuse detection. All subjects believed they had missed cases of elder abuse. Even experienced radiologists reported never having received a request from a referring physician to assess images for evidence suggestive of elder abuse. All subjects reported a desire for additional elder abuse training. Also, subjects identified radiographic findings or patterns potentially suggestive of elder abuse, including high-energy injuries such as upper rib fractures, injuries in multiple stages of healing, and injuries inconsistent with reported mechanism. CONCLUSION Radiologists are uniquely positioned to identify elder abuse. Though training in detection is currently lacking, providers expressed a desire for increased knowledge. In addition, radiologists were able to identify radiographic findings suggestive of elder abuse. On the basis of these findings, we plan to conduct additional studies to define pathognomonic injury patterns and to explore how to empower radiologists to incorporate detection into their practice.

We describe the use of 18F-NaF positron emission tomography (PET) whole-body imaging for the evaluation of skeletal trauma in a case of suspected child abuse. To our knowledge, 18F NaF PET has not been used in the past for the evaluation of child abuse. In our patient, this technique detected all sites of trauma shown by initial and follow-up skeletal surveys, including bilateral metaphyseal fractures of the proximal humeri. Fluorine-18 NaF PET has potential advantage over Tc-99m-labeled methylene diphosphonate (MDP) based upon superior image contrast and spatial resolution.

Melorheostosis is an uncommon, sporadic, sclerosing bone lesion that may affect the adjacent soft tissues. It has been associated with many entities such as osteopoikilosis, soft tissue vascular malformations, bone and soft tissue tumors, nephrotic syndrome, segmental limb contractures, osteosarcoma, desmoid tumor, and mesenteric fibromatosis. Synovial osteochondromatosis is a benign neoplasia of the hyaline cartilage presenting as nodules in the subsynovial tissue of a joint or tendon sheath. The intra-articular extension of melorheostosis mimicking synovial osteochondromatosis has not been reported before. In this article, the authors describe an unusual case mimicking synovial chondromatosis arising as a result of melorheostosis and their characteristic imaging findings.

Conditions mimicking penile fracture are extremely rare and have been seldom described. To describe a patient with false penile fracture who presented with superficial dorsal vein injury/thrombosis managed with ligation. A 33-year-old male presented with penile swelling and ecchymosis after intercourse. A penile ultrasound demonstrated a thrombosed superficial dorsal vein but also questionable fracture of the tunica albuginea. As the thrombus was expanding, he was emergently taken to the operating room for exploration and required only dorsal venous ligation. Postoperatively, patient's Sexual Health Inventory for Men score was 23, and he had no issues with erections or sexual intercourse. Early exploration of patients with suspected penile fracture provides excellent results with maintenance of erectile function. Also, in the setting of dorsal vein thrombosis, ligation preserves the integrity of the penile tissues and avoids unnecessary complications from conservative management.

Retroclival collections are rare lesions reported almost exclusively in children and strongly associated with trauma. We examine the incidence and imaging characteristics of retroclival collections in young children with abusive head trauma. We conducted a database search to identify children with abusive head trauma ≤ 3 years of age with brain imaging performed between 2007 and 2013. Clinical data and brain images of 65 children were analyzed. Retroclival collections were identified in 21 of 65 (32%) children. Ten (48%) were subdural, 3 (14%) epidural, 2 (10%) both, and 6 (28%) indeterminate. Only 8 of 21 retroclival collections were identifiable on CT and most were low or intermediate in attenuation. Eighteen of 21 retroclival collections were identifiable on MRI: 3 followed cerebral spinal fluid in signal intensity and 15 were bloody/proteinaceous. Additionally, 2 retroclival collections demonstrated a fluid-fluid level and 2 enhanced in the 5 children who received contrast material. Sagittal T1-weighted images, sagittal fluid-sensitive sequences, and axial FLAIR (fluid-attenuated inversion recovery) images showed the retroclival collections best. Retroclival collections were significantly correlated with supratentorial and posterior fossa subdural hematomas and were not statistically correlated with skull fracture or parenchymal brain injury. Retroclival collections, previously considered rare lesions strongly associated with accidental injury, were commonly identified in this cohort of children with abusive head trauma, suggesting that retroclival collections are an important component of the imaging spectrum in abusive head trauma. Retroclival collections were better demonstrated on MRI than CT, were commonly identified in conjunction with intracranial subdural hematomas, and were not significantly correlated with the severity of brain injury or with skull fractures.

A Discrete Fracture Network Model with Stress-Driven Nucleation and Growth

NASA Astrophysics Data System (ADS)

Lavoine, E.; Darcel, C.; Munier, R.; Davy, P.

2017-12-01

The realism of Discrete Fracture Network (DFN) models, beyond the bulk statistical properties, relies on the spatial organization of fractures, which is not issued by purely stochastic DFN models. The realism can be improved by injecting prior information in DFN from a better knowledge of the geological fracturing processes. We first develop a model using simple kinematic rules for mimicking the growth of fractures from nucleation to arrest, in order to evaluate the consequences of the DFN structure on the network connectivity and flow properties. The model generates fracture networks with power-law scaling distributions and a percentage of T-intersections that are consistent with field observations. Nevertheless, a larger complexity relying on the spatial variability of natural fractures positions cannot be explained by the random nucleation process. We propose to introduce a stress-driven nucleation in the timewise process of this kinematic model to study the correlations between nucleation, growth and existing fracture patterns. The method uses the stress field generated by existing fractures and remote stress as an input for a Monte-Carlo sampling of nuclei centers at each time step. Networks so generated are found to have correlations over a large range of scales, with a correlation dimension that varies with time and with the function that relates the nucleation probability to stress. A sensibility analysis of input parameters has been performed in 3D to quantify the influence of fractures and remote stress field orientations.

"It's Not All About Money": Toward a More Comprehensive Understanding of Financial Abuse in the Context of VAW.

Men's violence against women (VAW) is multifaceted and complex. Besides physical, psychological, and sexual violence, women subjected to VAW often suffer from economic hardship and financial abuse. Financial abuse involves different tactics used to exercise power and gain control over partners. Experiences of financial abuse make it difficult for women to leave an abusive partner and become self-sufficient. From an intersectional perspective, applying the concept of the continuum of violence, the aim of this article is to develop a more comprehensive understanding of how women subjected to men's violence in intimate relationships experience the complexity of financial abuse in their lives, in the context of VAW. Based on 19 in-depth interviews with women surviving domestic violence, the study describes how intertwined women's experiences of financial abuse are with other forms of abuse, influencing each other, simultaneously experienced as a distinct form of abuse with severe and longstanding consequences. Women in the study describe how men's abuse affects them financially, causing poverty and affecting their ability to have a reasonable economic standard. Financial abuse also causes women ill health, and damages their self-esteem and ability to work, associate, and engage in social life. The interviewed women describe how experiences of financial abuse continue across time, from their past into their present situation and molding beliefs about the future. According to the interviews, financial abuse in private life sometimes continues into the public sphere, reproduced by social workers mimicking patterns of ex-partners' abuse. Bringing out a more comprehensive understanding of the dynamic continuum of financial abuse, our results deepen knowledge about the complexity of VAW in women's lives, and thereby are important in processes of making victims of violence survivors of violence.

The importance of laboratory re-evaluation in cases of suspected child abuse - A case report.

In order to accurately diagnose child abuse or neglect, a physician needs to be familiar with diseases and medical conditions that can simulate maltreatment. Unrecognized cases of abuse may lead to insufficient child protection, whereas, on the other hand, over-diagnosis could be the cause of various problems for the family and their potentially accused members. Regarding child abuse, numerous cases of false diagnoses with undetected causes of bleeding are described in the scientific literature, but, specifically concerning leukemia in childhood, only very few case reports exist. Here, for the first time, we report a case of a 2-year-old boy who got hospitalized twice because of suspicious injuries and psychosocial conspicuities, in a family situation known for repeated endangerment of the child's well-being. After his first hospitalization with injuries typical for child abuse, but without paraclinical abnormalities, medical inspections were arranged periodically. The child was hospitalized with signs of repeated child abuse again five months later. During second admission, an acute lymphoblastic leukemia was revealed by intermittent laboratory examination, ordered due to new bruises with changes in morphology, identifiable as petechial hemorrhages. This case elucidates the discussion of known cases of leukemia in childhood associated with suspected child abuse in order to provide an overview of possible diseases mimicking maltreatment. To arrange necessary supportive examinations, a skillful interaction between pediatrician and forensic pathologist is crucial in the differentiation between accidental and non-accidental injury.

Children in homes with intimate partner violence (IPV) are at increased risk for physical abuse. We determined the frequency and injury patterns in children who underwent child abuse consultation after IPV exposure by retrospectively analyzing the "Examination of Siblings To Recognize Abuse" cohort of children referred for physical abuse. Children were selected who presented after IPV exposure. Among 2890 children evaluated by child abuse pediatricians, 61 (2.1%) patients presented after IPV exposure. Of the 61, 11 (18.0%) were exposed to IPV, but had no direct involvement in the IPV event, 36 (59.0%) sustained inadvertent trauma during IPV, and 14 (23.0%) were directly assaulted during IPV. Thirty-six patients (59.0%) had an injury: 31 (51.0%) had cutaneous injuries and 15 (24.6%) had internal injuries including fracture(s), intracranial or intra-abdominal injury. Of the 15 patients with internal injuries, 14 (93.3%) were less than 12 months old. Among the 36 patients with injuries, 16 (44.4%) had no report of direct injury, a report of a mechanism that did not explain the identified injuries, or a report of trauma without a specific mechanism. Five (13.9%) did not have physical examination findings to suggest the extent of their internal injuries. Injuries are present in a significant proportion of children presenting to Emergency Departments after IPV exposure. History and physical examination alone are insufficient to detect internal injuries especially in infants. These preliminary results support the need for future, prospective studies of occult injury in children exposed to IPV. Copyright © 2018 Elsevier Ltd. All rights reserved.

Ascorbic acid deficiency, iron overload and alcohol abuse underlie the severe osteoporosis in black African patients with hip fractures--a bone histomorphometric study.

Osteoporosis and femoral neck fractures (FNF) are uncommon in black Africans although osteoporosis accompanying iron overload (from traditional beer brewed in iron containers) associated with ascorbic acid deficiency (oxidative catabolism by iron) has been described from sub-Saharan Africa. This study describes histomorphometric findings of iliac crest bone biopsies and serum biochemical markers of iron overload and of alcohol abuse and ascorbic acid levels in 50 black patients with FNFs (29 M, 21 F), age 62 years (40-95) years (median [min-max]), and in age- and gender-matched black controls. We found evidence of iron overload in 88% of patients and elevated markers of alcohol abuse in 72%. Significant correlations between markers of iron overload and of alcohol abuse reflect a close association between the two toxins. Patients had higher levels of iron markers, i.e., siderin deposits in bone marrow (P < 0.0001), chemical non-heme bone iron (P = 0.012), and serum ferritin (P = 0.017) than controls did. Leukocyte ascorbic acid levels were lower (P = 0.0008) than in controls. The alcohol marker mean red blood cell volume was elevated (P = 0.002) but not liver enzymes or uric acid. Bone volume, trabecular thickness, and trabecular number were lower, and trabecular separation was greater in patients than in controls, all at P < 0.0005; volume, surface, and thickness of osteoid were lower and eroded surface was greater, all at P < 0.0001. There was no osteomalacia. Ascorbic acid deficiency accounted significantly for decrease in bone volume and trabecular number, and increase in trabecular separation, osteoid surface, and eroded surface; iron overload accounted for a reduction in mineral apposition rate. Alcohol markers correlated negatively with osteoblast surface and positively with eroded surface. Relative to reported data in white FNF patients, the osteoporosis was more severe, showed lower osteoid variables and greater eroded surface; FNFs occurred 12 years

While acoustic tissue mimicking materials have been explored for a variety of soft and hard biological tissues, no dental hard tissue mimicking materials have been characterized. Tooth phantoms are necessary to better understand acoustic phenomenology within the tooth environment and to accelerate the advancement of dental ultrasound imaging systems. In this study, soda lime glass and dental composite were explored as surrogates for human enamel and dentin, respectively, in terms of compressional velocity, attenuation, and acoustic impedance. The results suggest that a tooth phantom consisting of glass and composite can effectively mimic the acoustic behavior of a natural human tooth. PMID:18396919

A New Physics-Based Modeling of Multiple Non-Planar Hydraulic Fractures Propagation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Zhou, Jing; Huang, Hai; Deo, Milind

Because of the low permeability in shale plays, closely spaced hydraulic fractures and multilateral horizontal wells are generally required to improve production. Therefore, understanding the potential fracture interaction and stress evolution is critical in optimizing fracture/well design and completion strategy in multi-stage horizontal wells. In this paper, a novel fully coupled reservoir flow and geomechanics model based on the dual-lattice system is developed to simulate multiple non-planar fractures propagation. The numerical model from Discrete Element Method (DEM) is used to simulate the mechanics of fracture propagations and interactions, while a conjugate irregular lattice network is generated to represent fluid flowmore » in both fractures and formation. The fluid flow in the formation is controlled by Darcy’s law, but within fractures it is simulated by using cubic law for laminar flow through parallel plates. Initiation, growth and coalescence of the microcracks will lead to the generation of macroscopic fractures, which is explicitly mimicked by failure and removal of bonds between particles from the discrete element network. We investigate the fracture propagation path in both homogeneous and heterogeneous reservoirs using the simulator developed. Stress shadow caused by the transverse fracture will change the orientation of principal stress in the fracture neighborhood, which may inhibit or alter the growth direction of nearby fracture clusters. However, the initial in-situ stress anisotropy often helps overcome this phenomenon. Under large in-situ stress anisotropy, the hydraulic fractures are more likely to propagate in a direction that is perpendicular to the minimum horizontal stress. Under small in-situ stress anisotropy, there is a greater chance for fractures from nearby clusters to merge with each other. Then, we examine the differences in fracture geometry caused by fracturing in cemented or uncemented wellbore. Moreover, the impact of

Childhood panhypopituitarism may be acquired or congenital. Children with panhypopituitarism can present clinically with diabetes, growth failure, decreased bone density, and morbid obesity. In the forensic setting without the proper history, it can be misdiagnosed as child abuse or neglect. We report a case of a 3-year-old black girl who was admitted to the emergency room with apnea and subsequently died. While at the emergency department, it was discovered that the child had a fractured left hip and was severely growth retarded for age. The coroner wanted to rule out child abuse and/or neglect and requested an autopsy based on the physical findings identified by hospital staff. Significant findings at autopsy included small for age (15th percentile for age), hypoplastic brain/pituitary gland/adrenal gland/thyroid gland, abnormally formed skull with an occipital protuberance, a fractured left hip with decreased bone density, and central adiposity. Subsequent to the autopsy, it was discovered that at 6 weeks of age the child suffered from group B streptococci meningitis that resulted in panhypopituitarism. The panhypopituitarism then resulted in seizure activity, diabetes insipidus, and growth retardation. The authors hope this case report and review of the literature will assist investigators, pathologists, and clinicians in making a distinction between neglect or inflicted injury of child abuse and panhypopituitarism that can present with similar signs and symptoms.

Heparin-Mimicking Polymers: Synthesis and Biological Applications

2016-01-01

Heparin is a naturally occurring, highly sulfated polysaccharide that plays a critical role in a range of different biological processes. Therapeutically, it is mostly commonly used as an injectable solution as an anticoagulant for a variety of indications, although it has also been employed in other forms such as coatings on various biomedical devices. Due to the diverse functions of this polysaccharide in the body, including anticoagulation, tissue regeneration, anti-inflammation, and protein stabilization, and drawbacks of its use, analogous heparin-mimicking materials are also widely studied for therapeutic applications. This review focuses on one type of these materials, namely, synthetic heparin-mimicking polymers. Utilization of these polymers provides significant benefits compared to heparin, including enhancing therapeutic efficacy and reducing side effects as a result of fine-tuning heparin-binding motifs and other molecular characteristics. The major types of the various polymers are summarized, as well as their applications. Because development of a broader range of heparin-mimicking materials would further expand the impact of these polymers in the treatment of various diseases, future directions are also discussed.

The phenylazomethine dendrimer (DPA) has a layer-by-layer electron density gradient that is an analog of the Bohr atom (atom mimicry). In combination with electron pair mimicry, the polymerization of this atom-mimicking dendrimer was achieved. The valency of the mimicked atom was controlled by changing the chemical structure of the dendrimer. By mimicking a divalent atom, a one-dimensional (1D) polymer was obtained, and by using a planar tetravalent atom mimic, a 2D polymer was obtained. These poly(dendrimer) polymers could store Lewis acids (SnCl 2 ) in their unoccupied orbitals, thus indicating that these poly(dendrimer) polymers consist of a series of nanocontainers.

To see if mothers who were sexually abused in their own childhood are at increased risk of their children being sexually abused and to see if prior sexual abuse in mothers affects their parenting abilities. Sixty-seven mothers whose children had been sexually abused by others and 65 control mothers were asked about sexual abuse in their own childhood. The sexually abused children of mothers who had been sexually abused in their own childhood were compared with the sexually abused children of mothers who had not suffered child sexual abuse as children. Comparisons were made on self-esteem, depression and behavior in the children. Thirty-four percent of mothers of sexually abused children gave a history of sexual abuse in their own childhoods, compared with 12% of control mothers. Assessment of the sexually abused children for self-esteem, depression and behavior at the time of diagnosis, after 18 months and after 5 years showed no difference in any of these measures at any of the three time intervals between those whose mothers had suffered child sexual abuse and those whose mothers had not been abused. In this study, sexual abuse in a mother's own childhood was related to an increased risk of sexual abuse occurring in the next generation, although prior maternal sexual abuse did not effect outcome in children who were sexually abused.

Screening injured children for physical abuse or neglect in emergency departments: a systematic review.

Screening markers are used in emergency departments (EDs) to identify children who should be assessed for possible physical abuse and neglect. We conducted three systematic reviews evaluating age, repeat attendance and injury type as markers for physical abuse or neglect in injured children attending EDs. We included studies comparing markers in physically abused or neglected children and non-abused injured children attending ED or hospital. We calculated likelihood ratios (LRs) for age group, repeat attendance and injury type (head injury, bruises, fractures, burns or other). Given the low prevalence of abuse or neglect, we considered that an LR of 10 or more would be clinically useful. All studies were poor quality. Infancy increased the risk of physical abuse or neglect in severely injured or admitted children (LRs 7.7-13.0, 2 studies) but was not strongly associated in children attending the ED (LR 1.5, 95% CI: 0.9, 2.8; one study). Repeat attendance did not substantially increase the risk of abuse or neglect and may be confounded by chronic disease and socio-economic status (LRs 0.8-3.9, 3 studies). One study showed no evidence that the type of injury substantially increased the risk of physical abuse or neglect in severely injured children. There was no evidence that any of the markers (infancy, type of injury, repeated attendance) were sufficiently accurate (i.e. LR >or= 10) to screen injured children in the ED to identify those requiring paediatric assessment for possible physical abuse or neglect. Clinicians should be aware that among injured children at ED a high proportion of abused children will present without these characteristics and a high proportion of non-abused children will present with them. Information about age, injury type and repeat attendances should be interpreted in this context.

Elder abuse.

Kurrle, Susan

2004-10-01

Elder abuse is a common and yet often unrecognised problem in our community. With up to 5% of the community dwelling older population being victims of abuse, the general practitioner has a pivotal role in identifying this abuse. This article provides an outline of the definition of elder abuse, describes the types of abuse seen and the reasons for occurrence of abuse. It summarises the role of the GP in the identification and management of abuse and provides guidance on intervention strategies. Case studies are used to illustrate the issues discussed. Elder abuse is defined as any pattern of behaviour which causes physical, psychological, financial or social harm to an older person. The role of the GP in identifying abuse is critical. The vast majority of older people visit their GP at least once a year, and the GP often has a long standing relationship with their patient and the patient's family. They are therefore ideally placed to identify elder abuse.

Biomaterial-associated infections critically compromise the functionality and performance of the medical devices, and pose a serious threat to human healthcare. Recently, natural DNase enzyme has been recognized as a potent material to prevent bacterial adhesion and biofilm formation. However, the vulnerability of DNase dramatically limits its long-term performance in antibacterial applications. In this work, DNase-mimicking polymer brushes were constructed to mimic the DNA-cleavage activity as well as the macromolecular scaffold of the natural DNase. The bacteria repellent efficacy of DNase-mimicking polymer brush-functionalized surface was comparable to that of the DNase-functionalized surface. More importantly, due to their inherent stability, DNase-mimicking polymer brushes presented the much better performance in inhibiting bacterial biofilm development for prolonged periods of time, as compared to the natural DNase. The as-developed DNase-mimicking polymer brush-functionalized surface presents a promising approach to combat biomaterial-associated infections.

Substance abuse by either victim or perpetrator has long been associated with violence and abuse. Sparse research is available regarding elder abuse and its association with substance abuse. The objective of this study was to evaluate the association of state-reported domestic elder abuse with regional levels of substance abuse. Census demographic and elder abuse data were sorted into substate regions to align with the substance use treatment-planning regions for 2269 US counties. From the 2269 US counties there were 229 substate regions in which there were 213,444 investigations of abuse. For the other Ns (reports and substantiations) there were fewer counties and regions. See first sentence of data analyses and first sentence of results. Elder abuse report rates ranged from .03 to .41% (80 regions), investigation rates .001 to .34% (229 regions), and substantiation rates 0 to .22% (184 regions). Elder abuse investigations and substantiations were associated with various forms of substance abuse. Higher investigation rates were significantly associated with a higher rate of any illicit drug use in the past month, a lower median household income, lower proportion of the population graduated high school, and higher population of Hispanics. Higher substantiation rates were significantly associated with higher rate of illicit drug use in the past month and higher population of Hispanics. It may be worthwhile for administrators of violence programs to pay particular attention to substance abuse among their clients and in their community's environment, especially if older persons are involved. Measures of documented elder abuse at the county level are minimal. To be able to associate substance abuse with elder abuse is a significant finding, realizing that the substance abuse can be by the victim or the perpetrator of elder abuse.

For exact age determinations of bone fractures in a forensic context (e.g. in cases of child abuse) improved knowledge of the time course of the healing process and use of non-invasive modern imaging technology is of high importance. To date, fracture dating is based on radiographic methods by determining the callus status and thereby relying on an expert's experience. As a novel approach, this study aims to investigate the applicability of magnetic resonance imaging (MRI) for bone fracture dating by systematically investigating time-resolved changes in quantitative MR characteristics after a fracture event. Prior to investigating fracture healing in children, adults were examined for this study in order to test the methodology for this application. Altogether, 31 MR examinations in 17 subjects (♀: 11 ♂: 6; median age 34 ± 15 y, scanned 1-5 times over a period of up to 200 days after the fracture event) were performed on a clinical 3T MR scanner (TimTrio, Siemens AG, Germany). All subjects were treated conservatively for a fracture in either a long bone or in the collar bone. Both, qualitative and quantitative MR measurements were performed in all subjects. MR sequences for a quantitative measurement of relaxation times T1 and T2 in the fracture gap and musculature were applied. Maps of quantitative MR parameters T1, T2, and magnetisation transfer ratio (MTR) were calculated and evaluated by investigating changes over time in the fractured area by defined ROIs. Additionally, muscle areas were examined as reference regions to validate this approach. Quantitative evaluation of 23 MR data sets (12 test subjects, ♀: 7 ♂: 5) showed an initial peak in T1 values in the fractured area (T1=1895 ± 607 ms), which decreased over time to a value of 1094 ± 182 ms (200 days after the fracture event). T2 values also peaked for early-stage fractures (T2=115 ± 80 ms) and decreased to 73 ± 33 ms within 21 days after the fracture event. After that time point, no

Research demonstrates that substance-abusing individuals report substantially higher rates of childhood sexual and physical abuse than the general population. This study sought to test a method of identifying substance-abusing clients with histories of childhood sexual and/or physical abuse and to explore the differences between those reporting childhood abuse and those not. Files of substance abusing clients from two distinct time periods were examined for reports of childhood abuse. At Time 1 (n = 399) clients were not systematically asked about experiences of childhood abuse, and at Time 2 (n = 305) clients were routinely asked about this issue. Results indicate that significantly more male and female clients disclosed childhood abuse at Time 2. Additionally, male clients reporting childhood abuse appeared more distressed than those not reporting abuse; female clients reporting childhood abuse did not appear more distressed than their counterparts.

Factors influencing the incidence of maxillofacial fractures.

Maxillofacial injuries occur in a significant proportion of trauma patients. Trauma causes considerable economic expense due to procedural costs, the time a patient is off work, and the associated loss of income. For these reasons, it is an important health and economic issue. The aim of this study is to discuss the factors that may influence the incidence of maxillofacial fractures. As it is necessary to determine trends to help guide the development of new methods of injury prevention, preventative measures are also discussed. An electronic search was undertaken in March 2011, including articles published between 1980 and 2011 with the terms "facial fractures" and "maxillofacial fractures" in the title. The texts of epidemiological studies were reviewed in order to identify factors that may influence the incidence of maxillofacial fractures. From the selected articles, ten factors were identified: age, gender, geographic region and cultural aspects, socioeconomic status, temporal and climatic influence, use of alcohol and drugs, compliance with road traffic legislation, domestic violence, osteoporosis, and etiology of the maxillofacial trauma. Care of injured patients should include not only management of the acute phase, but also combine preventive programs and interventional programs aimed at reducing the incidence of maxillofacial fractures. Therefore, there is a need to ensure strict compliance of traffic rules and regulations, implement improvement in automotive safety devices, organize prevention programs to minimize assaults, implement school education in alcohol abuse and handling potentially hostile situations (especially for men), improve protection during sporting activities, and legislate wearing of protective headgear in workers. Preventive strategies remain the cheapest way to reduce direct and indirect costs of the sequelae of trauma. Societal attitudes and behaviors must be modified before a significant reduction in the incidence of maxillofacial

Quantitative magnetic resonance imaging (qMRI) offers several advantages in imaging and determination of soft tissue alterations when compared to qualitative imaging techniques. Although applications in brain and muscle tissues are well studied, its suitability to quantify relaxation times of intact and injured bone tissue, especially in children, is widely unknown. The objective observation of a fracture including its age determination can become of legal interest in cases of child abuse or maltreatment. Therefore, the aim of this study is the determination of time dependent changes in intact and corresponding injured bones in immature rats via qMRI, to provide the basis for an objective and radiation-free approach for fracture dating. Thirty-five MR scans of 7 Sprague-Dawley rats (male, 4 weeks old, 100 ± 5 g) were acquired on a 3T MRI scanner (TimTrio, Siemens AG, Erlangen, Germany) after the surgical infliction of an epiphyseal fracture in the tibia. The images were taken at days 1, 3, 7, 14, 28, 42 and 82 post-surgery. A proton density-weighted and a T1-weighted 3D FLASH sequence were acquired to calculate the longitudinal relaxation time T1 of the fractured region and the surrounding tissues. The calculation of T1 in intact and injured bone resulted in a quantitative observation of bone development in intact juvenile tibiae as well as the bone healing process in the injured tibiae. In both areas, T1 decreased over time. To evaluate the differences in T1 behaviour between the intact and injured bone, the relative T1 values (bone-fracture) were calculated, showing clear detectable alterations of T1 after fracture occurrence. These results indicate that qMRI has a high potential not only for clinically relevant applications to detect growth defects or developmental alterations in juvenile bones, but also for forensically relevant applications such as the dating of fractures in cases of child abuse or maltreatment.

Despite recent improvements in surgical devices, complex proximal humerus fractures internal fixation still encounters frequent mechanical failures. The aim of this study was to confirm that the Bilboquet device (a design mimicking the cup-and-ball game) helps solving mechanical difficulties associated with these fractures internal fixation and to present a simplified version of the original surgical procedure. This non-randomised prospective study included 22 fractures in 22 patients, mean age: 70 years. According to the Neer classification there were three-part fractures in seven cases and four-part fractures in 15 cases. Fractures were all reduced and treated by internal fixation in a simplified surgical procedure using the Bilboquet device. Mean postoperative follow-up was 34 months. The mean Constant score was 66 and the weighted Constant score was 86. Mean active forward elevation was 108° and mean active external rotation was 28°. No per- or postoperative complications occurred. Initial reduction of the tuberosity was incomplete in four cases. Union was obtained in all fractures. There was no secondary tilting of the head, and no migration or pseudarthrosis of the tuberosities. Five patients developed postoperative avascular necrosis of the humeral head. The Bilboquet staple component provides a supporting platform for the entire humeral head area. This peripheral stabilization associated with tension band wiring explains the lack of secondary displacement in these cases. Although the Bilboquet device provides a solution to the mechanical problems of complex fractures of the proximal humerus, it does not solve the problem of secondary avascular necrosis of the humeral head, which occurred in 23% of the patients in this series and in 33% of patients in the four-part fractures subgroup.

2017-11-01

Poor and minority children with injuries concerning for abuse are evaluated and diagnosed for abuse differentially. We hypothesized that 2 steps in the decision-making process would influence evaluation and diagnosis: social intuition from meeting the family and objective social information associated with child abuse risk. Between 2009 and 2013, 32 child abuse pediatricians (CAPs) submitted 730 child abuse consultations including original medical evaluations and diagnoses. CAPs evaluated and diagnosed each other's cases. Comparisons of evaluations and diagnoses were made by levels of social understanding available to the CAP: meeting the family (social intuition and information), reading the case (social information), and reading the case without social information. Evaluations were compared with a consensus gold standard by using logistic regression modeling adjusting for child and CAP characteristics. Diagnostic categories were compared by level of social understanding and diagnostic certainty by using contingency tables. CAPs without access to social intuition were approximately twice as likely to perform gold standard evaluations for neurotrauma and long bone fracture compared with CAPs who met families. Diagnostic agreement fell from 73.3% (95% confidence interval [CI]: 70.1%-76.5%) when social information was present to 66.5% (95% CI: 63.1%-70.0%) when social information was restricted. In cases with less certainty, agreement dropped to 51.3% (95% CI: 46.0%-56.7%). Social intuition and information play a role in the physical child abuse decision-making process, which may contribute to differential diagnosis. Simple interventions including decision tools, check lists, and peer review may structure evaluations to ensure children's equal treatment. Copyright © 2017 by the American Academy of Pediatrics.

The current study examined the rate and psychiatric correlates of sexual abuse involving the use of digital technologies by the offender in a wide sample of juvenile victims. Sociodemographic, abuse, and psychiatric characteristics of 662 sexually abused children and adolescents were evaluated. Of these, 93 reported that digital devices were used by the offender in several ways to facilitate the sexual abuse. The offender-victim relationship was initiated through the Internet in 39 victims. Involvement of digital technologies in sexual abuse was significantly associated with penetrative and recurrent form of sexual abuse commited by multiple offenders with coexisting violence. Additionally, victims of sexual abuse with a digital component were 4.21 times more likely to develop any psychopathology, 3.77 times more likely to have depression, and 2.14 times more likely to have post-traumatic stress disorder as a result of sexual abuse. These results indicated that the offender's use of digital technology may aid the initiation and facilitation of the sexual abuse of youths and may relate to more severe outcomes. This study revealed the importance of raising the awareness of professionals and the community about the potential risks associated with digital technologies and sexual abuse. Mental health professionals should consider this additional form of victimization, especially when dealing with sexual abuse victims.

Adrenal tumors present with clinical features and signs unique to their specific hormonal hypersecretion. However, there have been cases in which the clinical expression has been in conflict with the histologic features of the tumor. In this communication we report an unusual clinical presentation of an adrenal cortical tumor with histologic features of an oncocytoma that clinically mimicked a pheochromocytoma. A 49-year old man was referred to our Unit due to type B aortic dissection and a mass of the left adrenal gland. Computed tomography and magnetic resonance imaging confirmed the presence of aortic dissection extending from the left subclavian artery to both iliac arteries and also revealed a 6 cm tumor on the left adrenal gland. Preoperative endocrine evaluation showed a near tenfold increase of urinary vanillylmandelic acid (VMA) and metanephrine values. Transperitoneal laparoscopic adrenalectomy was successfully performed. The adrenal tumor proved to be an adrenal cortical neoplasm with histologic features of oncocytoma. Although the case of an adrenal cortical adenoma clinically mimicking a pheochromocytoma has been described in the literature, to the best of our knowledge, there has been no previous report of an adrenal cortical neoplasm with predominant features of oncocytoma.

Analysis of propagation mechanisms of stimulation-induced fractures in rocks

NASA Astrophysics Data System (ADS)

Krause, Michael; Renner, Joerg

2016-04-01

Effectivity of geothermal energy production depends crucially on the heat exchange between the penetrated hot rock and the circulating water. Hydraulic stimulation of rocks at depth intends to create a network of fractures that constitutes a large area for exchange. Two endmembers of stimulation products are typically considered, tensile hydro-fractures that propagate in direction of the largest principal stress and pre-existing faults that are sheared when fluid pressure reduces the effective normal stress acting on them. The understanding of the propagation mechanisms of fractures under in-situ conditions is still incomplete despite intensive research over the last decades. Wing-cracking has been suggested as a mechanism of fracture extension from pre-existent faults with finite length that are induced to shear. The initiation and extension of the wings is believed to be in tensile mode. Open questions concern the variability of the nominal material property controlling tensile fracture initiation and extension, the mode I facture toughness KIC, with in-situ conditions, e.g., its mean-stress dependence. We investigated the fracture-propagation mechanism in different rocks (sandstones and granites) under varying conditions mimicking those representative for geothermal systems. To determine KIC-values we performed 3-point bending experiments. We varied the confining pressure, the piston velocity, and the position of the chevron notch relative to the loading configuration. Additional triaxial experiments at a range of confining pressures were performed to study wing crack propagation from artificial flaws whose geometrical characteristics, i.e., length, width, and orientation relative to the axial load are varied. We monitored acoustic emissions to constrain the spacio-temporal evolution of the fracturing. We found a significant effect of the length of the artificial flaw and the confining pressure on wing-crack initiation but did not observe a systematic dependence

Cognitive and emotional differences between abusive and non-abusive fathers.

Francis, Karen J; Wolfe, David A

2008-12-01

Abusive fathers perpetrate a substantial portion of child physical abuse. Despite this, little is known about how they differ from non-abusive fathers. This study compared a broad range of cognitive and affective factors between physically abusive and non-abusive fathers. Abusive (n=24) and non-abusive (n=25) fathers completed standard measures assessing their experience and expression of anger, mental health, parenting stress, and their empathy and perceptions of children's socio-emotional signals. Abusive fathers differed from comparisons on almost all constructs. They experienced more anger and were more likely to express that anger aggressively. They reported more mental health concerns (such as depression, hostility, and paranoid ideation), more stress in parenting, and significantly less empathy for their children. They were also more likely to perceive children's emotional expressions as depicting negative emotions, such as anger and disgust. Abusive fathers struggle with a myriad of difficulties that likely contribute to their problematic parenting. These difficulties are both inter- and intra-personal in nature. The findings suggest that abusive fathers require comprehensive assessment that includes mental health screening. Interventions should be selected carefully to target abusive fathers' high levels of negative affect and negative perceptions. Treatment strategies should address problems related to parenting style (e.g., managing stress and interpretation of children's socioemotional signals) as well as their personal adjustment (e.g., cognitive behavioral strategies for regulating affect and cognitive distortions).

Biomechanical investigation of impact induced rib fractures of a porcine infant surrogate model.

This study investigated the structural, biomechanical and fractographic features of rib fractures in a piglet model, to test the hypothesis that fist impact, apart from thoracic squeezing, may result in lateral costal fractures as observed in abused infants. A mechanical fist with an accelerometer was constructed and fixed to a custom jig. Twenty stillborn piglets in the supine position were impacted on the thoracic cage. The resultant force versus time curves from the accelerometer data showed a number of steps indicative of rib fracture. The correlation between impact force and number of fractures was statistically significant (Pearson׳s r=0.528). Of the fractures visualized, 15 completely pierced the parietal pleura of the thoracic wall, and 5 had butterfly fracture patterning. Scanning electron microscopy showed complete bone fractures, at the zone of impact, were normal to the axis of the ribs. Incomplete vertical fractures, with bifurcation, occurred on the periphery of the contact zone. This work suggests the mechanism of rib failure during a fist impact is typical of the transverse fracture pattern in the anterolateral region associated with cases of non-accidental rib injury. The impact events investigated have a velocity of ~2-3m/s, approximately 2×10(4) times faster than previous quasi-static axial and bending tests. While squeezing the infantile may induce buckle fractures in the anterior as well as posterior region of the highly flexible bones, a fist punch impact event may result in anterolateral transverse fractures. Hence, these findings suggest that the presence of anterolateral rib fractures may result from impact rather than manual compression. Copyright © 2016 Elsevier Ltd. All rights reserved.

Types of abuse and risk factors associated with elder abuse.

Detecting elder abuse is challenging because it is a taboo, and many cases remain unreported. This study aimed to identify types of elder abuse and to investigate its associated risk factors. Retrospective analyses of 903 dossiers created at an Independent Complaints Authority for Old Age in the Canton of Zurich, Switzerland, from January 1, 2008 to October 31, 2012. Characteristics of victims and perpetrators, types of abuse, and associated risk factors related to the victim or the perpetrator were assessed. Bi- and multivariate analysis were used to identify abuse and neglect determinants. A total of 150 cases reflected at least one form of elder abuse or neglect; 104 cases were categorised as abuse with at least one type of abuse (overall 135 mentions), 46 cases were categorised as neglect (active or passive). Psychological abuse was the most reported form (47%), followed by financial (35%), physical (30%) and anticonstitutional abuse (18%). In 81% of the 150 cases at least two risk factors existed. In 13% no associated risk factor could be identified. Compared with neglect, elders with abuse were less likely to be a nursing home resident than living at home (odds ratio [OR] 0.02, 95% confidence interval [CI] 0.00-0.19). In addition, they were more likely to be cohabiting with their perpetrators (OR 18.01, 95% CI 4.43-73.19). For the majority of the reported elder abuse cases at least two associated risk factors could be identified. Knowledge about these red flags and a multifaceted strategy are needed to identify and prevent elder abuse.

To critically evaluate the use of lateral blood pool imaging in athletes with lower limb pain and with a clinical suspicion of stress fracture. Two experienced nuclear medicine physicians evaluated 3-phase bone scans using 99mTc-methylene diphosphonate performed in 50 consecutive patients referred from a specialist sports injury clinic for suspected tibial stress fracture. The vascularity to the tibia as seen on the blood pool (second phase) images in the anterior/posterior views was compared with the lateral/medial view assessments. Stress fractures were presumed to be present when on the delayed images (third phase) there was a focal or fusiform area of increased tracer uptake involving the tibial cortex. Shin splints which are a recognized cause of lower limb pain in athletes mimicking stress fracture were diagnosed if increased tracer uptake was seen extending along the posterior tibial surface with no significant focal or fusiform area of uptake within this. Inter-reviewer agreement for the assessment of vascularity was also assessed using Cohen's Kappa scores. Twenty-four stress fractures in 24 patients and 66 shin splints in 40 patients were diagnosed. In 18 patients stress fracture and shin splints coexisted. In 10 patients no tibial pathology was identified. Of the 24 patients diagnosed with stress fractures, lateral/medial blood pool imaging was superior in the assessment of blood pool activity (P < 0.001) identifying increased vascularity in 21 cases compared with the anterior/posterior views positive in only 11 cases. The inter-reviewer agreement was near perfect for lateral/medial views, κ = 0.86 while very good for anterior/posterior views, κ = 0.68. In patients with suspected tibial stress fractures, lateral views of the tibia provide the optimal method for evaluation of vascularity. Prospective studies with quantitative or semi-quantitative assessment of skeletal vascularity could provide supplementary information relating to the pathophysiology

Classical metaphyseal lesions thought to be pathognomonic of child abuse are often artifacts or indicative of metabolic bone disease.

PubMed

Miller, Marvin; Mirkin, L David

2018-06-01

The objective of the present study was to review the histopathology in the original articles by authors Kleinman and Marks that described the specificity of the classical metaphyseal lesion for child abuse and to determine if there were any oversights in the authors' analysis. We reviewed the histopathology of the original studies that equated the classical metaphyseal lesion with child abuse. We compared this with the histopathology of metaphyseal fractures caused by known accidental, severe trauma in children and reviewed the histopathology of artifacts that can sometimes be produced in bone histology preparations. Acute classical metaphyseal lesions showed no hemorrhage, and the chronic classical metaphyseal showed islands of cartilage proliferation at the metaphyses and growth plate, findings consistent with rickets and other metabolic bone disorders. Some of the acute metaphyseal lesions were consistent with artifacts. We believe the original studies that equate the classical metaphyseal lesion with child abuse are flawed. The most compelling observation that challenges the histopathology of the classical metaphyseal lesion as being a fracture is the absence of hemorrhage in the acute classical metaphyseal lesion. We hypothesize that some of the classical metaphyseal lesions were artifacts or represent metabolic bone disorders that were not considered and that these two non-traumatic explanations may have been the basis of the abnormal bone findings.

Preparation and Exceptional Mechanical Properties of Bone-Mimicking Size-Tuned Graphene Oxide@Carbon Nanotube Hybrid Paper.

PubMed

Oh, Jun Young; Kim, Yern Seung; Jung, Yeonsu; Yang, Seung Jae; Park, Chong Rae

2016-02-23

The self-assembled nanostructures of carbon nanomaterials possess a damage-tolerable architecture crucial for the inherent mechanical properties at both micro- and macroscopic levels. Bone, or "natural composite," has been known to have superior energy dissipation and fracture resistance abilities due to its unique load-bearing hybrid structure. However, few approaches have emulated the desirable structure using carbon nanomaterials. In this paper, we present an approach in fabricating a hybrid composite paper based on graphene oxide (GO) and carbon nanotube (CNT) that mimicks the natural bone structure. The size-tuning strategy enables smaller GO sheets to have more cross-linking reactions with CNTs and be homogeneously incorporated into CNT-assembled paper, which is advantageous for effective stress transfer. The resultant hybrid composite film has enhanced mechanical strength, modulus, toughness, and even electrical conductivity compared to previously reported CNT-GO based composites. We further demonstrate the usefulness of the size-tuned GOs as the "stress transfer medium" by performing in situ Raman spectroscopy during the tensile test.

A 26-year-old Caucasian female with keratoconus presented with an acutely painful and red left eye. Visual acuity on presentation was 3/60. Slit lamp examination revealed localised Descemet's membrane break with iris partially plugging it. There was a bulging stromal cyst which would intermittently flatten and reform. The appearance when the cyst was flattened mimicked a full thickness corneal perforation. However, no obvious overlying epithelial defect was detected and an intermittent leakage through micro-perforations in the corneal epithelium was the probable cause of the variable appearance. The anterior chamber reformed and iris plug freed following an insertion of a bandage contact lens and taped eyelid. On follow-up, the Descement's membrane had healed with visual acuity improving to 6/18. Our case illustrates the importance of identifying corneal hydrops mimicking a full thickness perforation as conservative management has a greater chance of recovery.

Sexual abuses.

PubMed

Abel, G G; Rouleau, J L

1995-03-01

The sexual abuses described in this article are occurring so frequently that they constitute a public health problem. Superficially they appear to be quite dissimilar because they involve individuals of different ages, different settings, and different power relationships. Basic to each of them, however, is an absence of consent by the victim and the misuse of power by the perpetrator in order to accomplish the abuse. We now have an adequate understanding of each of these abuses and it is now time to make a concerted effort to stop these abuses. This will require the combined efforts of the education of the public, improved identification of the abuses, treatment of the victims, and an appropriate criminal justice response combined with treatment of the perpetrator.

Upon onset of PTSD, the patient's substance abuse became a full-blown addiction that was highly resistant to treatment. It became evident that her substance abuse symbolically repeated her traumatization. In reexperiencing the affects associated with her earlier trauma (despair, denial, shame, and helplessness) as part of her substance abuse and in the transference, the patient was able to gain mastery over these affects and, subsequently, was able to achieve a stable recovery from both illnesses.

Primary tumors metastasizing to the oral cavity are extremely rare. Lung is one of the most common primary sources of metastases to the tongue. Although the incidence of lung cancer is increasing, tongue metastasis as the initial presentation of the tumor remains uncommon. Due to the rarity of tongue metastasis, little is known about its imaging findings. Herein we report the magnetic resonance imaging and clinical findings of a lingual metastasis, mimicking an abscess, from a primary lung cancer.

Inflammatory myofibroblastic tumors (IMTs) are rare. IMTs of the head and neck occur in all age groups, from neonates to old age, with the highest incidence occurring in childhood and early adulthood. An IMT has been defined as a histologically distinctive lesion of uncertain behavior. This article describes an unusual case of IMT mimicking apical periodontitis in the mandible of a 42-year-old man. At first presentation, the patient showed spontaneous pain and percussion pain at teeth #28 to 30, which continued after initial endodontic treatment. Panoramic radiography revealed a radiolucent lesion at the site. Cone-beam computed tomographic imaging showed osteolytic lesions, suggesting an aggressive neoplasm requiring incisional biopsy. Histopathological examination indicated an IMT. The lesion was removed en bloc under general anesthesia, and the patient manifested no clinical evidence of recurrence for 24 months. Lesions of nonendodontic origin should be included in the differential diagnosis of apical periodontitis. Every available diagnostic tool should be used to confirm the diagnosis. Cone-beam computed tomographic imaging is very helpful for differential diagnosis in IMTs mimicking apical periodontitis. Copyright © 2015 American Association of Endodontists.

Sheahan, Chelsea L; Pica, Emily; Pozzulo, Joanna D

2017-09-01

The purpose of the current study was to examine the role of victim age, defendant age, and type of abuse on mock juror decision making. Mock jurors ( N = 556) read a trial transcript in which a soccer coach was accused of sexual abuse or physical abuse against a player. The victim's age (child, adolescent, or young adult), the defendant's age (young, middle age, or older adult), and the type of abuse (sexual or physical) were varied. Mock jurors provided a dichotomous and continuous verdict and rated their perceptions of the victim and the defendant. Although no differences on mock jurors' dichotomous verdict were found due to victim age, defendant age, or type of abuse, mock jurors provided higher guilt ratings when the abuse was sexual and both the victim and defendant were described as young adults. Similarly, mock jurors rated the victim more positively when the victim was described as a young adult (vs. child) for both sexual and physical abuse cases, and rated the defendant more positively when the victim was described as a child compared with young adult in sexual abuse cases. These findings suggest that mock jurors were largely influenced by victim age, particularly when the victim was described as an adult compared with a child.

[Child psychiatric assessment and the debate regarding the abuse of abuse].

PubMed

Fegert, J M

1995-03-01

The current discussion on false allegations in sexual abuse cases has led to a polarization in the views expressed about the credibility of children. Some authors even speak of a "child sexual accuse syndrome" or of a "sexual abuse allegation in divorce" (SAID) syndrome. A phenomenological analysis of the multiple reasons for misinterpretations is presented. Instead of stressing the importance only of false positives in child sexual abuse questions, an attempt is made to describe reasons for false negatives. Based on a retrospective analysis of 50 consecutive child psychiatric experts in connection with court cases, there does not appear to be an increase in false accusations. Rather, only about one third of the cases even involved suspected sexual abuse. Sexual abuse allegations were much more frequent in girls than in boys. Of 20 abuse allegations we judge four to be false allegations. In only one of these cases, that of an adolescent girl who had been abused in childhood, was the false allegation intended.

Alcohol abuse as a risk factor for and consequence of child abuse.

The relationship between child abuse and the use or abuse of alcohol has two aspects. First, some findings have indicated that parental alcohol abuse may be associated with the physical or sexual abuse of children. Research findings in this area remain inconsistent, however. Second, the experience of being abused as a child may increase a person's risk for alcohol-related problems as an adult. This relationship has best been demonstrated in women who had been victims of childhood abuse. Several factors most likely contribute to or influence this relationship, including coping skills; antisocial behavior; and psychological problems, such as posttraumatic stress disorder.

Natural fractures have a significant influence on the propagation geometry of hydraulic fractures in fractured reservoirs. True triaxial volumetric fracturing experiments, in which random natural fractures are created by placing cement blocks of different dimensions in a cuboid mold and filling the mold with additional cement to create the final test specimen, were used to study the factors that influence the hydraulic fracture propagation geometry. These factors include the presence of natural fractures around the wellbore, the dimension and volumetric density of random natural fractures and the horizontal differential stress. The results show that volumetric fractures preferentially formed when natural fractures occurred around the wellbore, the natural fractures are medium to long and have a volumetric density of 6-9%, and the stress difference is less than 11 MPa. The volumetric fracture geometries are mainly major multi-branch fractures with fracture networks or major multi-branch fractures (2-4 fractures). The angles between the major fractures and the maximum horizontal in situ stress are 30°-45°, and fracture networks are located at the intersections of major multi-branch fractures. Short natural fractures rarely led to the formation of fracture networks. Thus, the interaction between hydraulic fractures and short natural fractures has little engineering significance. The conclusions are important for field applications and for gaining a deeper understanding of the formation process of volumetric fractures.

Pediatric facial fractures, although uncommon, have a significant impact on public health and the US economy by the coexistence of other injuries and developmental deformities. Violence is one of the most frequent mechanisms leading to facial fracture. Teaching hospitals, while educating future medical professionals, have been linked to greater resource utilization in differing scenarios. This study was designed to compare the differences in patient characteristics and outcomes between teaching and non-teaching hospitals for violence-related pediatric facial fractures. Using the 2000-2009 Kids' Inpatient Database, 3881 patients younger than 18 years were identified with facial fracture and external cause of injury code for assault, fight, or abuse. Patients admitted at teaching hospitals were compared to those admitted at non-teaching hospitals in terms of demographics, injuries, and outcomes. Overall, 76.2% of patients had been treated at teaching hospitals. Compared to those treated at non-teaching hospitals, these patients were more likely to be younger, non-white, covered by Medicaid, from lower income zip codes, and have thoracic injuries; but mortality rate was not significantly different. After adjusting for potential confounders, teaching status of the hospital was not found as a predictor of either longer lengths of stay (LOS) or charges. There is an insignificant difference between LOS and charges at teaching and non-teaching hospitals after controlling for patient demographics. This suggests that the longer LOS observed at teaching hospitals is related to these institutions being more often involved in the care of underserved populations and patients with more severe injuries.

Substantiation of drug exposure in cases with alleged maltreatment is important to provide proper treatment and services to these children and their families. A study performed at University of Iowa Hospitals and Clinics showed that 30% of pediatric patients with burn injuries, which were due to child maltreatment, were also exposed to illicit drugs. The children presenting to the University of Iowa Hospitals and Clinics with alleged maltreatment have been tested for illicit substances since 2004. The objective of this study was to analyze the presence of illicit drug exposure in the pediatric subpopulation admitted to pediatric inpatient and outpatient units for an evaluation for abuse/neglect. The study design is a retrospective chart review. Using hospital databases, every pediatric chart with a child abuse/neglect allegation was retrieved. The association between risk factors and clinical presentation and illicit drug test result was assessed. Excel and SAS were used for statistical analysis. Institutional review board approval was obtained to conduct this study. Six hundred sixty-five charts met study inclusion criteria for child abuse/neglect allegation. Of those, 232 cases were tested for illicit drugs between 2004 and 2008 per the testing protocol. Thirty-four cases (14.7%) tested positive on a drug test. Positive test rates based on clinical presentation were 28.6% (18/63) in neglect cases, 16.1% (5/31) in cases with soft tissue injuries, 14.3% (4/28) in burn injuries, 10.0% (2/20) in cases with sexual abuse, 7.1% (2/28) in cases with fractures, and 4.8% (3/62) in abusive head trauma cases. There were long-term abuse findings in 129 children (55.6%). Logistic regression analysis revealed that positive drug testing was most significantly associated with clinical symptoms suggesting physical abuse or neglect versus sexual abuse (odds ratio [OR] = 6.70; 95% confidence interval [CI], 1.26-35.49; P = 0.026), no or public health insurance versus those with

Computer simulation of stair falls to investigate scenarios in child abuse.

To demonstrate the usefulness of computer simulation techniques in the investigation of pediatric stair falls. Since stair falls are a common falsely reported injury scenario in child abuse, our specific aim was to investigate the influence of stair characteristics on injury biomechanics of pediatric stair falls by using a computer simulation model. Our long-term goal is to use knowledge of biomechanics to aid in distinguishing between accidents and abuse. A computer simulation model of a 3-year-old child falling down stairs was developed using commercially available simulation software. This model was used to investigate the influence that stair characteristics have on biomechanical measures associated with injury risk. Since femur fractures occur in unintentional and abuse scenarios, biomechanical measures were focused on the lower extremities. The number and slope of steps and stair surface friction and elasticity were found to affect biomechanical measures associated with injury risk. Computer simulation techniques are useful for investigating the biomechanics of stair falls. Using our simulation model, we determined that stair characteristics have an effect on potential for lower extremity injuries. Although absolute values of biomechanical measures should not be relied on in an unvalidated model such as this, relationships between accident-environment factors and biomechanical measures can be studied through simulation. Future efforts will focus on model validation.

Mistakes in diagnosing non-accidental injury: 10 years' experience

Fifty children who were referred to the child abuse team in Leeds over the 10 years 1976-86 with suspected non-accidental injury were found to have conditions which mimicked non-accidental injury. These included impetigo (nine children) and blue spots (five children). Five children who presented with multiple bruising had haemostatic disorders. Eight children had disorders of the bone. Five children had been previously abused physically. Four showed evidence of neglect. One had evidence of non-accidental injury as well as the condition mimicking abuse. It is emphasised that when child abuse is suspected a sensitive and thorough assessment should be carried out by a paediatrician who is experienced in this. ImagesFIG 1 PMID:3133026

Displaced intra-articular calcaneal fractures with incongruity of the posterior facet of the subtalar joint, loss of height, and axial malalignment. High perioperative risk, soft tissue infection, advanced peripheral arterial disease (stage III), neurogenic osteoarthropathy, poor patient compliance (e. g., substance abuse). Extended lateral approach with the patient placed on the uninjured side. Reduction of the anatomic shape and joint surfaces according to the preoperative CT-based planning. Reduction of the medial wall and step-wise reconstruction of the posterior facet from medial to lateral. Reduction of the tuberosity and anterior process fragments to the posterior joint block and temporary fixation with Kirschner wires. Internal fixation with an anatomic lateral plate in a locking or nonlocking mode. Alternatively less invasive internal fixation with a calcaneus nail over a sinus tarsi approach for less severe fracture types. The lower leg is immobilized in a brace until the wound is healed. Range of motion exercises of the ankle and subtalar joints are initiated on the second postoperative day. Patients are mobilized in their own shoe with partial weight bearing of 20 kg for 6-12 weeks depending on fracture severity and bone quality.

Sexual maturation and control issues among sexually abused and non-abused anorexia patients.

PubMed

Walsh, J; Burns, F

2000-09-01

To assess the relative salience of the maintenance of control and the avoidance of sexual maturation as sources of motivation for maintaining pathological eating behaviours among sexually abused anorexic patients. A two-factor mixed experimental design was employed. Three independent groups (sexually abused anorexics (N = 12); non-abused anorexics (N = 9); non-anorexic/non-abused controls (N = 12)) constituted the between-subjects factor. Allocation to abuse/non-abuse group was dependent upon replies to a questionnaire-based measure of unwanted sexual experience. The within-subjects factor comprised three conditions in which words of various colours were presented to participants for colour-naming (Stroop, 1935). The conditions were represented by lists of neutral words, sexual maturation words, and control-related words. Two trials were carried out in each condition and mean response times were measured. Within-group analyses revealed that interference was greater from sexual maturation words than from control-related words among the sexually-abused anorexics, but of equal magnitude among non-abused counterparts. Between-groups analyses found that abused patients experienced marginally greater cognitive interference from sexual maturation words than the non-abused patients. Theoretically, support is offered for elaborated schematic models of cognitive processing. Clinically, treatment interventions may need to pay particular attention to issues of sexual maturation among sexually abused anorexic patients.

The complexities of elder abuse.

2016-01-01

Elder abuse is a growing societal concern, affecting at least 1 in 10 older Americans. Researchers and practitioners alike consistently assert that a dramatic discrepancy exists between the prevalence rates of elder abuse and the number of elder abuse cases reported. As a field of study, recognition and understanding of elder abuse is still emerging. Comparing findings of a small, but growing, body of literature on perceived and substantiated cases of elder abuse is challenging because there is no uniform term or agreed-upon definition used among state governments, researchers, health care and service providers, and advocates. This article summarizes current understanding of elder abuse, including what constitutes elder abuse, risk factors for elder abuse, perpetrators of elder abuse, and outcomes of elder abuse. Issues associated with the detection of elder abuse and intervention strategies for victims of abuse are addressed. In the final section, potential roles and contributions of psychologists for advancing elder abuse research, professional practice, and policy development are highlighted.

Background We assessed the frequency and types of ankle fractures that frequently occur during parachute landings of special operation unit personnel and analyzed the causes. Methods Fifty-six members of the special force brigade of the military who had sustained ankle fractures during parachute landings between January 2005 and April 2010 were retrospectively analyzed. The injury sites and fracture sites were identified and the fracture types were categorized by the Lauge-Hansen and Weber classifications. Follow-up surveys were performed with respect to the American Orthopedic Foot and Ankle Society ankle-hindfoot score, patient satisfaction, and return to preinjury activity. Results The patients were all males with a mean age of 23.6 years. There were 28 right and 28 left ankle fractures. Twenty-two patients had simple fractures and 34 patients had comminuted fractures. The average number of injury and fractures sites per person was 2.07 (116 injuries including a syndesmosis injury and a deltoid injury) and 1.75 (98 fracture sites), respectively. Twenty-three cases (41.07%) were accompanied by posterior malleolar fractures. Fifty-five patients underwent surgery; of these, 30 had plate internal fixations. Weber type A, B, and C fractures were found in 4, 38, and 14 cases, respectively. Based on the Lauge-Hansen classification, supination-external rotation injuries were found in 20 cases, supination-adduction injuries in 22 cases, pronation-external rotation injuries in 11 cases, tibiofibular fractures in 2 cases, and simple medial malleolar fractures in 2 cases. The mean follow-up period was 23.8 months, and the average follow-up American Orthopedic Foot and Ankle Society ankle-hindfoot score was 85.42.

The aim of this study was to assess the mediating role of dissatisfaction with friendships in adulthood in the associations between psychological abuse in childhood, substance abuse distress in childhood, and incident psychiatric problems (IPPs) in adulthood over 13 years of follow-up. We used data collected from 1994 to 2008 within the framework of the Tromsø Study (N = 9502), a representative, longitudinal, prospective cohort study. Poisson regression analysis was used to assess the associations between psychological abuse, substance abuse distress, dissatisfaction with friendships in adulthood, and IPPs in adulthood. Indirect effects and proportion mediated (%) were assessed with the difference-in-coefficients method. Psychological abuse (relative risk [RR] = 1.66, 95% confidence interval [CI]: 1.45-1.89) and substance abuse distress in childhood (RR = 1.38, 95% CI: 1.18-1.62) were associated with an increased risk of dissatisfaction with friendships in adulthood. Dissatisfaction with friendships in adulthood was associated with an increased risk of IPPs in adulthood (RR = 1.71, 95% CI: 1.33-2.20). Moreover, dissatisfaction with friendships in adulthood mediated 9.31% (95% CI: 4.25-14.57) of the association between psychological abuse in childhood and IPPs in adulthood, and 9.17% (95% CI: 4.35-16.33) of the association between substance abuse distress in childhood and IPPs in adulthood. Dissatisfaction with friendships in adulthood mediates a minor proportion of the associations between psychological abuse, substance abuse distress, and IPPs in adulthood. Interventions aimed at decreasing dissatisfaction with friendships may dampen some of the effect of psychological abuse and substance abuse distress in childhood on IPPs in adulthood.

Discrete Fracture Network Characterization of Fractured Shale Reservoirs with Implications to Hydraulic Fracturing Optimization

NASA Astrophysics Data System (ADS)

Jin, G.

2016-12-01

Shales are important petroleum source rocks and reservoir seals. Recent developments in hydraulic fracturing technology have facilitated high gas production rates from shale and have had a strong impact on the U.S. gas supply and markets. Modeling of effective permeability for fractured shale reservoirs has been challenging because the presence of a fracture network significantly alters the reservoir hydrologic properties. Due to the frequent occurrence of fracture networks, it is of vital importance to characterize fracture networks and to investigate how these networks can be used to optimize the hydraulic fracturing. We have conducted basic research on 3-D fracture permeability characterization and compartmentization analyses for fractured shale formations, which takes the advantages of the discrete fracture networks (DFN). The DFN modeling is a stochastic modeling approach using the probabilistic density functions of fractures. Three common scenarios of DFN models have been studied for fracture permeability mapping using our previously proposed techniques. In DFN models with moderately to highly concentrated fractures, there exists a representative element volume (REV) for fracture permeability characterization, which indicates that the fractured reservoirs can be treated as anisotropic homogeneous media. Hydraulic fracturing will be most effective if the orientation of the hydraulic fracture is perpendicular to the mean direction of the fractures. A DFN model with randomized fracture orientations, on the other hand, lacks an REV for fracture characterization. Therefore, a fracture permeability tensor has to be computed from each element. Modeling of fracture interconnectivity indicates that there exists no preferred direction for hydraulic fracturing to be most effective oweing to the interconnected pathways of the fracture network. 3-D fracture permeability mapping has been applied to the Devonian Chattanooga Shale in Alabama and the results suggest that an

To determine the prevalence of sexual abuse among high school (secondary and preparatory) students, male and female, throughout Mexico, and its relationship with drug abuse. Data were obtained from the National Survey of Drug Use in Schools applied in November and December, 1991. A total of 61,779 students, 51.8% men and 47.1% women, with a mean age of 14.4 years completed the self-applied questionnaire. Sexual abuse was explored from the perspective of the abusers and of the victims. The prevalence of sexual abuse in adolescent victims was 4.3% and no statistically significant differences were found between sexes. The prevalence of sexual aggressors was 2.5%. Men coerced someone else in a higher proportion than women. Adolescent women experienced sexual abuse at a younger age than men and they also reported a higher percentage of intrafamily abuse. Men reported friends as the most frequent aggressors. Victims and aggressors of both sexes reported a significantly higher drug consumption than students without these antecedents. The differences in the experience of sexual abuse between men and women are described. In particular, the fact that sexual abuse in men mainly occurs outside the family sphere, while in women it is mainly within the family and at a younger age than in men. Additionally, the need for further research focusing on the consequences on mental health of infantile and adolescent sexual abuse and drug consumption is emphasized, considering the characteristics of each gender.

This study develops a new class of gellan gum-based tissue-mimicking phantom material and a model to predict and control the elastic modulus, thermal conductivity, and electrical conductivity by adjusting the mass fractions of gellan gum, propylene glycol, and sodium chloride, respectively. One of the advantages of gellan gum is its gelling efficiency allowing highly regulable mechanical properties (elastic modulus, toughness, etc). An experiment was performed on 16 gellan gum-based tissue-mimicking phantoms and a regression model was fit to quantitatively predict three material properties (elastic modulus, thermal conductivity, and electrical conductivity) based on the phantom material's composition. Based on these material properties and the regression model developed, tissue-mimicking phantoms of porcine spinal cord and liver were formulated. These gellan gum tissue-mimicking phantoms have the mechanical, thermal, and electrical properties approximately equivalent to those of the spinal cord and the liver.

Incarcerated women have high rates of substance abuse problems and trauma. A variety of variables may influence whether these women seek help or are referred for substance abuse problems. This study reports an exploratory project on service utilization among incarcerated substance-dependent women (N = 40) in southeastern Idaho. Using self-report and interview tools, most participants reported some substance abuse treatment history, although extent and types of treatment varied. Most of the women also reported some type of childhood abuse. Age, income, and consequences of alcohol and other drug use related positively to substance abuse treatment. However, severity of childhood sexual abuse and current trauma symptoms were negatively correlated with substance abuse treatment episodes. These women may use substances to cope with childhood trauma or may not perceive the substance abuse system as responsive to their co-occurring trauma symptoms. Copyright © 2011 Elsevier Inc.

MR imaging plays a vital role in the diagnosis and management of hip fractures in all age groups, in a large spectrum of patient groups spanning the elderly and sporting population. It allows a confident exclusion of fracture, differentiation of bony from soft tissue injury and an early confident detection of fractures. There is a spectrum of MR findings which in part is dictated by the type and cause of the fracture which the radiologist needs to be familiar with. Judicious but prompt utilisation of MR in patients with suspected hip fractures has a positive therapeutic impact with healthcare cost benefits as well as social care benefits.

The purpose of this paper is to provide a review of the current literature uncovering specific factors associated with self-harm and suicidality among young Asian American women, as well as to present the Fractured Identity Model as a framework for understanding these factors. This paper offers concrete suggestions for the development of culturally competent interventions to target suicidality, substance abuse, and mental illness among young Asian American women. Empirical studies and theory-based papers featured in peer-reviewed journals between 1990 and 2014 were identified through scholarly databases, such as PubMed, MEDLINE, PsycINFO, JSTOR, and Google Scholar. We identified several factors associated with suicidality among young Asian American women: (1) family dynamics, or having lived in a household where parents practice "disempowering parenting styles," (2) substance use/abuse, and (3) untreated mental illness(es), which are exacerbated by the stigma and shame attached to seeking out mental health services. The Fractured Identity Model by Hahm et al. (2014) is presented as a possible pathway from disempowering parenting to suicidal and self-harm behaviors among this population, with substance abuse playing a significant mediating role. Research limitations/implications - Our review focused on Asian American women, substance use among Asian Americans, and mental health among Asian Americans. Literature that focused on Asians living in Asia or elsewhere outside of the USA was excluded from this review; the review was limited to research conducted in the USA and written in the English language. The complex interplay among Asian American culture, family dynamics, gender roles/expectations, and mental health justifies the development of a suicide and substance abuse intervention that is tailored to the culture- and gender-specific needs of Asian Pacific Islander young women. It is imperative for professionals in the fields of public health, mental health

Exploring the controversy in child abuse pediatrics and false accusations of abuse.

PubMed

Gabaeff, Steven C

2016-01-01

There is a controversy in child abuse pediatrics between an established corps of child abuse pediatricians aligned with hospital colleagues and law enforcement, and a multi-specialty challenger group of doctors and other medical professionals working with public interest lawyers. The latter group questions the scientific validity of the core beliefs of child abuse pediatricians and believes that there are a substantial number of false accusations of abuse occurring. An unproven primary hypothesis, crafted around 1975 by a small group of pediatricians with an interest in child abuse, lies at the foundation of child abuse pediatrics. With no scientific study, it was hypothesized that subdural hemorrhage (SDH) and retinal hemorrhage (RH) were diagnostic of shaking abuse. That hypothesis became the so-called "shaken baby syndrome." Through the period 1975-1985, in a coordinated manner, these child abuse specialists coalesced under the American Academy of Pediatrics and began working with district attorneys and social workers, informing them of the ways in which their hypothesis could be applied to prosecutions of child abuse and life-altering social service interventions. In a legal context, using then-prevailing evidentiary rules which treated scientific expert testimony as valid if it was "generally accepted" in the field, they represented falsely that there was general acceptance of their hypothesis and therefore it was valid science. As the ability to convict based on this unproven prime hypothesis (SDH and RH equals abuse) increased, some defense attorneys were professionally compelled by their own doubts to reach out to experts from other fields with experience with SDH and RH, trauma, and biomechanics, for second opinions. Medical and legal challenges to the established thinking soon emerged, based on both old and new evidenced-based literature. As the intensity of the controversy increased, the probability of false accusation became more apparent and the need

Physical abuse of the elderly is a significant public health concern. The true prevalence of all types is unknown, and under-reporting is known to be significant. The geriatric population is projected to increase dramatically over the next 10 years, and the number of abused individuals is projected to increase also. It is critical that health care providers feel competent in addressing physical elder abuse. This article presents cases illustrating the variety of presenting symptoms that may be attributed to physical elder abuse. Copyright © 2014 Elsevier Inc. All rights reserved.

Rare extraskeletal Ewing's sarcoma mimicking as adenocarcinoma of the sigmoid.

Extraskeletal Ewing's sarcoma (EES) is a rare finding in comparison with Ewing's sarcoma of bone and usually manifests in young patients. However, even in older patients, one must consider the diagnosis. In this case, we describe a 52-year-old woman diagnosed with EES, mimicking as adenocarcinoma of the sigmoid. The tumor was not visualized by a multi-slice spiral computed tomography of the abdomen and pelvis with intravenous contrast, and eventually the diagnosis was made by positive immunohistochemical staining for CD99 and by molecular testing for EWSR1 translocation. This combination of the patient's age and the localization of the tumor mimicking an adenocarcinoma of the sigmoid has never been described before.

Tension pneumocephalus mimicking septic shock: a case report.

2018-02-01

Tension pneumocephalus can lead to rapid neurologic deterioration. We report for the first time its association with aseptic systemic inflammatory response syndrome mimicking septic shock and the efficacy of prompt neurosurgical intervention and critical care support in treating this condition. A 64-year-old man underwent 2-stage olfactory groove meningioma resection. The patient developed altered mental status and gait instability on postoperative day 6. Imaging showed significant pneumocephalus. The patient subsequently developed worsening mental status, respiratory failure, and profound shock requiring multiple vasopressors. Bedside needle decompression, identification and repair of the cranial fossa defect, and critical care support led to improved mental status and reversal of shock and multiorgan dysfunction. Thorough evaluation revealed no evidence of an underlying infection. In this case, tension pneumocephalus incited an aseptic systemic inflammatory response syndrome mimicking septic shock. Prompt neurosurgical correction of pneumocephalus and critical care support not only improved neurologic status, but also reversed shock. Such a complication indicates the importance of close monitoring of patients with progressive pneumocephalus.

Cerebello-thalamo-cortical loops play a major role in the emergence of pathological tremors and voluntary rhythmic movements. It is unclear whether these loops differ anatomically or functionally in different types of tremor. We compared age- and sex-matched groups of patients with Parkinson's disease or essential tremor and healthy controls (n = 34 per group). High-density 256-channel EEG and multi-channel EMG from extensor and flexor muscles of both wrists were recorded simultaneously while extending the hands against gravity with the forearms supported. Tremor was thereby recorded from patients, and voluntarily mimicked tremor was recorded from healthy controls. Tomographic maps of EEG-EMG coherence were constructed using a beamformer algorithm coherent source analysis. The direction and strength of information flow between different coherent sources were estimated using time-resolved partial-directed coherence analyses. Tremor severity and motor performance measures were correlated with connection strengths between coherent sources. The topography of oscillatory coherent sources in the cerebellum differed significantly among the three groups, but the cortical sources in the primary sensorimotor region and premotor cortex were not significantly different. The cerebellar and cortical source combinations matched well with known cerebello-thalamo-cortical connections derived from functional MRI resting state analyses according to the Buckner-atlas. The cerebellar sources for Parkinson's tremor and essential tremor mapped primarily to primary sensorimotor cortex, but the cerebellar source for mimicked tremor mapped primarily to premotor cortex. Time-resolved partial-directed coherence analyses revealed activity flow mainly from cerebellum to sensorimotor cortex in Parkinson's tremor and essential tremor and mainly from cerebral cortex to cerebellum in mimicked tremor. EMG oscillation flowed mainly to the cerebellum in mimicked tremor, but oscillation flowed mainly

Establishing "abuse-deterrence equivalence" for generic abuse-deterrent opioid formulations: A proposed development framework.

Setnik, Beatrice; Cone, Edward J

2016-01-01

Abuse-deterrent formulations are one strategy for mitigating the epidemic of prescription opioid abuse. Regulatory guidance documents describe the requirements for developing abuse-deterrent formulations of novel drugs and formulations; however, they do not address "abuse-deterrence equivalence" for generic formulations. As generics may be produced with different excipients and formulations compared to reference drugs, differences in their properties may impact their abuse-deterrent features. Currently, it is unclear what specific studies are needed to support generic abuse-deterrence claims. This commentary outlines several recommendations on the in vitro and in vivo testing required, including the conditions for conducting a human abuse potential study.

Measuring Economic Abuse in the Lives of Survivors: Revising the Scale of Economic Abuse.

Recent attention has been given by researchers to understanding how abusers use economic abuse strategies. Unfortunately, limited measures are available to accurately understand the prevalence of economic abuse in the lives of survivors. Recently, researchers created the 28-item Scale of Economic Abuse (SEA) but further validation is needed. This article describes the psychometric evaluation of the SEA through confirmatory and exploratory factor analyses using data collected with 120 survivors of abuse. The findings provide evidence for the reliability and validity of the SEA-12 as a shorter instrument to measure economic abuse as a distinct form of abuse. © The Author(s) 2015.

To compare 2 different femoral neck augmentation techniques at improving the mechanical strength of the femoral neck. Twenty pairs of human cadaveric femora were randomly divided into 2 groups. In 1 group, the femora were augmented with a steel spiral; the other group with the cemented technique. The untreated contralateral side served as an intraindividual control. Fracture strength was evaluated using an established biomechanical testing scenario mimicking a fall on the greater trochanter (Hayes fall). The peak load to failure was significantly higher in the steel spiral group (P = 0.0024) and in the cemented group (P = 0.001) compared with the intraindividual controls. The peak load to failure showed a median of 3167 N (1825-5230 N) in the spiral group and 2485 N (1066-4395 N) in the spiral control group. The peak load to failure in the cemented group was 3698 N (SD ± 1249 N) compared with 2763 N (SD ± 1335 N) in the cement control group. Furthermore, fracture displacement was clearly reduced in the steel spiral group. Femoral augmentations using steel spirals or cement-based femoroplasty are technically feasible procedures. Our results demonstrate that a prophylactic reinforced proximal femur has higher strength when compared with the untreated contralateral limb. Prophylactic augmentation has potential to become an auxiliary treatment option to protect the osteoporotic proximal femur against fracture.

The electrocardiogram (ECG) is useful in the diagnosis of cardiac and non-cardiac conditions. Rigors due to shivering can cause electrocardiogram artifacts mimicking various cardiac rhythm abnormalities. We describe an 80-year-old Sri Lankan man with an abnormal electrocardiogram mimicking narrow complex tachycardia during the immediate post-operative period. Electrocardiogram changes caused by muscle tremor during rigors could mimic a narrow complex tachycardia. Identification of muscle tremor as a cause of electrocardiogram artifact can avoid unnecessary pharmacological and non-pharmacological intervention to prevent arrhythmias.

Hemorrhagic shock (hS) interacts with the posttraumatic immune response and fracture healing in multiple trauma. Due to the lack of a long-term survival multiple trauma animal models, no standardized analysis of fracture healing referring the impact of multiple trauma on fracture healing was performed. We propose a new long-term survival (21 days) murine multiple trauma model combining hS (microsurgical cannulation of carotid artery, withdrawl of blood and continuously blood pressure measurement), femoral (osteotomy/external fixation) and tibial fracture (3-point bending technique/antegrade nail). The posttraumatic immune response was measured via IL-6, sIL-6R ELISA. The hS was investigated via macrohemodynamics, blood gas analysis, wet-dry lung ration and histologic analysis of the shock organs. We proposed a new murine long-term survival (21 days) multiple trauma model mimicking clinical relevant injury patterns and previously published human posttraumatic immune response. Based on blood gas analysis and histologic analysis of shock organs we characterized and standardized our murine multiple trauma model. Furthermore, we revealed hemorrhagic shock as a causative factor that triggers sIL-6R formation underscoring the fundamental pathophysiologic role of the transsignaling mechanism in multiple trauma. © 2015 Orthopaedic Research Society.

We present two cases of infants who died under suspicious circumstances. After clinical and legal investigations, non-accidental constrictive asphyxia inflicted by one of the parents was established. The first case presents a to date not yet reported, unique mechanism of trauma. In order to stop his daughter from crying, the father admitted that he sometimes sat on his baby while she was lying on the bed. Occasionally increasing his force by pulling with his hands on the bottom of the bed. In the second case tight swaddling and encircling chest compression was the causative mechanism. In both cases the father was sentenced to imprisonment with mandate psychiatric care. Only two previous reports of this uncommon and relatively unknown cause of child abuse, called constrictive asphyxia, are known. In all reported cases static loading of the chest resulted in rib fractures and demise of the child. This rare abusive mechanism should be known to pediatric radiologists and pathologists.

Imaging findings of mimickers of hepatocellular carcinoma

PubMed Central

Lee, Eunchae; Jang, Hyun-Jung

2015-01-01

Radiological imaging plays a crucial role in the diagnosis of hepatocellular carcinoma (HCC) as the noninvasive diagnosis of HCC in high-risk patients by typical imaging findings alone is widely adopted in major practice guidelines for HCC. While imaging techniques have markedly improved in detecting small liver lesions, they often detect incidental benign liver lesions and non-hepatocellular malignancy that can be misdiagnosed as HCC. The most common mimicker of HCC in cirrhotic liver is nontumorous arterioportal shunts that are seen as focal hypervascular liver lesions on dynamic contrast-enhanced cross-sectional imaging. Rapidly enhancing hemangiomas can be easily misdiagnosed as HCC especially on MR imaging with liver-specific contrast agent. Focal inflammatory liver lesions mimic HCC by demonstrating arterial-phase hypervascularity and subsequent washout on dynamic contrast-enhanced imaging. It is important to recognize the suggestive imaging findings for intrahepatic cholangiocarcinoma (CC) as the management of CC is largely different from that of HCC. There are other benign mimickers of HCC such as angiomyolipomas and focal nodular hyperplasia-like nodules. Recognition of their typical imaging findings can reduce false-positive HCC diagnosis.

Dedifferentiated liposarcoma is typically a nonlipogenic high-grade sarcoma that arises from well-differentiated liposarcoma. It most commonly presents as a large mass in the retroperitoneum. Significant involvement of the gastrointestinal tract by dedifferentiated liposarcoma is uncommon. We present a unique case of dedifferentiated liposarcoma radiographically mimicking a primary colon mass with resulting intussusception; stranding of the adjacent adipose tissue was presumed to be a secondary reactive change. On histopathologic analysis of the hemicolectomy specimen, a high-grade sarcoma was seen growing through the colonic wall, and the majority of the surrounding pericolonic adipose tissue was actually composed of well-differentiated liposarcoma with characteristic fibrous bands rather than benign fat with reactive fibrosis. This case raises awareness that well-differentiated liposarcoma and dedifferentiated liposarcoma can rarely present as a primary intestinal mass mimicking colon cancer or other more common entities. When radiographic examination shows a perigastrointestinal or retroperitoneal fatty mass and/or stranding of the fat adjacent to a solid gastrointestinal mass, this unusual scenario should be considered in the radiologic differential diagnosis. Pathologists should keep dedifferentiated liposarcoma in the initial histologic differential diagnosis for any high-grade spindle cell tumor of the retroperitoneum or intra-abdominal visceral organs.

Treatment of acetabular fractures remains one of the most challenging tasks that orthopaedic surgeons face. An accurate assessment of the injuries and preoperative planning are essential for an excellent reduction. The purpose of this study was to evaluate the feasibility, accuracy and effectiveness of performing 3D printing technology and computer-assisted virtual surgical procedures for preoperative planning in acetabular fractures. We hypothesised that more accurate preoperative planning using 3D printing models will reduce the operation time and significantly improve the outcome of acetabular fracture repair. Ten patients with acetabular fractures were recruited prospectively and examined by CT scanning. A 3-D model of each acetabular fracture was reconstructed with MIMICS14.0 software from the DICOM file of the CT data. Bone fragments were moved and rotated to simulate fracture reduction and restore the pelvic integrity with virtual fixation. The computer-assisted 3D image of the reduced acetabula was printed for surgery simulation and plate pre-bending. The postoperative CT scan was performed to compare the consistency of the preoperative planning with the surgical implants by 3D-superimposition in MIMICS14.0, and evaluated by Matta's method. Computer-based pre-operations were precisely mimicked and consistent with the actual operations in all cases. The pre-bent fixation plates had an anatomical shape specifically fit to the individual pelvis without further bending or adjustment at the time of surgery and fracture reductions were significantly improved. Seven out of 10 patients had a displacement of fracture reduction of less than 1mm; 3 cases had a displacement of fracture reduction between 1 and 2mm. The 3D printing technology combined with virtual surgery for acetabular fractures is feasible, accurate, and effective leading to improved patient-specific preoperative planning and outcome of real surgery. The results provide useful technical tips in

Peroxidase-mimicking nanozymes offer unique advantages in terms of high stability and low cost over natural peroxidase for applications in bioanalysis, biomedicine, and the treatment of pollution. However, the design of high-efficiency peroxidase-mimicking nanozymes remains a great challenge. In this study, we adopted a structural-design approach through hybridization of cube-CeO 2 and Pt nanoparticles to create a new peroxidase-mimicking nanozyme with high efficiency and excellent stability. Relative to pure cube-CeO 2 and Pt nanoparticles, the as-hybridized Pt/cube-CeO 2 nanocomposites display much improved activities because of the strong metal-support interaction. Meanwhile, the nanocomposites also maintain high catalytic activity after long-term storage and multiple recycling. Based on their excellent properties, Pt/cube-CeO 2 nanocomposites were used to construct high-performance colorimetric biosensors for the sensitive detection of metabolites, including H 2 O 2 and glucose. Our findings highlight opportunities for the development of high-efficiency peroxidase-mimicking nanozymes with potential applications such as diagnostics, biomedicine, and the treatment of pollution. © 2018 Wiley-VCH Verlag GmbH & Co.

2017-10-01

The aim of this study was to assess proximal humeral fracture patterns using 3-dimensional computed tomography images and relate them to the normal osseous landmarks and soft-tissue attachments. Forty-eight 3-dimensional computed tomography scans of proximal humeral fractures were retrospectively collected, and the fractures were transcribed onto proximal humeral templates. We analyzed the common location and orientation of the fracture lines, with a focus on fractures of the articular surface, tuberosities, metaphysis, and proximal diaphysis. These fractures were compared with the attachments of the rotator cuff and glenohumeral capsule. Fifty-two percent of the fractures involved the articular surface. No fractures passed through the bicipital groove, and fractures were more commonly found on the posterior lesser tuberosity and on the anterior greater tuberosity, coinciding with the intervals between the rotator cuff tendon insertions. Intracapsular fractures of the calcar were more common (68%) than extracapsular fractures (32%). On the anterolateral aspect of the proximal humerus, fractures radiated from the articular margin, vertically down through the tuberosity zone between the rotator cuff footprints, meeting horizontally oriented fractures in the metaphyseal zone. On the posterior aspect, vertical fractures from the tuberosity zone continued downward to the metaphyseal zone adjacent to the infraspinatus and teres minor footprints. Fractures of the proximal humerus follow characteristic patterns. Fractures frequently split the greater tuberosity and are closely related to the intervals of the rotator cuff attachments.

A 3-year-old boy child died at home. The circumstances of death appeared unclear to the police investigators and a medicolegal autopsy was carried out. External examination revealed diffuse ecchymoses of varying colours. Postmortem imaging using plain X-rays and multislice computed tomography (MSCT) was performed prior to autopsy and pathological study. These investigations revealed fractures at the posterior arch of the ninth left rib. No cerebral and pericerebral traumatic lesions were diagnosed. In the abdomen, haemoperitoneum and pneumoperitoneum secondary to duodenal perforation and liver laceration were observed. At autopsy, a complete pancreatic fracture and duodenal transection were noted, accounting for the MSCT appearance. Furthermore, autopsy revealed the presence of bilateral intramuscular intercostal haemorrhages and a fracture of the eighth left rib at its posterior arch. This case report illustrates the valuable assistance rendered by MSCT as well as its limitations in diagnosing abuse when a child dies in unclear circumstances. Copyright © 2010 Elsevier Ireland Ltd.

Hydraulic fracturing has become a valuable technique for the stimulation of oil, gas, and geothermal reservoirs in a variety of reservoir rocks. In many applications, only short fractures are needed for economic production. In low-permeability reservoirs, however, long penetrating fractures are generally needed, and in this case, natural fractures can be the cause of many adverse effects during a fracture treatment.

The result may range from negligible to catastrophic depending on the values of the ancillary treatment and reservoir parameters, such as the treating pressure, in-situ stresses, pore pressure, orientations of the natural fractures relative to principal in-situ stresses, spacing and distribution of the natural fractures, permeability, etc. Field observations from mineback experiments at DOE's Nevada Test Site and the multiwell experiment in Colorado, laboratory tests, and analyses of these data are integrated to describe the complex fracture behavior found and to provide guidelines for predicting when this complex fracturing will occur.« less

Objectives To analyze the trend of dextromethorphan abuse in California and to compare these findings with national trends. Design A 6-year retrospective review. Setting California Poison Control System (CPCS), American Association of Poison Control Centers (AAPCC), and Drug Abuse Warning Network (DAWN) databases from January 1, 1999, to December 31, 2004. Participants All dextromethorphan abuse cases reported to the CPCS, AAPCC, and DAWN. The main exposures of dextromethorphan abuse cases included date of exposure, age, acute vs long-term use, coingestants, product formulation, and clinical outcome. Main Outcome Measure The annual proportion of dextromethorphan abuse cases among all exposures reported to the CPCS, AAPCC, and DAWN databases. Results A total of 1382 CPCS cases were included in the study. A 10-fold increase in CPCS dextromethorphan abuse cases from 1999 (0.23 cases per 1000 calls) to 2004 (2.15 cases per 1000 calls) (odds ratio, 1.48; 95% confidence interval, 1.43–1.54) was identified. Of all CPCS dextromethorphan abuse cases, 74.5% were aged 9 to 17 years; the frequency of cases among this age group increased more than 15-fold during the study (from 0.11 to 1.68 cases per 1000 calls). Similar trends were seen in the AAPCC and DAWN databases. The highest frequency of dextromethorphan abuse occurred among adolescents aged 15 and 16 years. The most commonly abused product was Coricidin HBP Cough & Cold Tablets. Conclusions Our study revealed an increasing trend of dextromethorphan abuse cases reported to the CPCS that is paralleled nationally as reported to the AAPCC and DAWN. This increase was most evident in the adolescent population. PMID:17146018

The increased use of opioid pain medication has been mirrored by the increased misuse and abuse of these drugs. As part of a multidisciplinary approach to this epidemic, pharmaceutical companies, with the encouragement of the Food and Drug Administration, have increased the development of abuse-deterrent formulations. While all have the goal of treating pain while mitigating misuse and abuse, there are different technologies utilized to impart the abuse-deterrent properties. The goal of this paper is to review the basis of abuse-deterrent formulations, the different types and approaches of some of the abuse-deterrent products, and their current regulatory status in the USA.

As an important, yet underrecognized form of substance abuse, inhalant abuse crosses all demographic, ethnic, and socioeconomic boundaries, causing significant morbidity and mortality in school-aged and older children. This review presents current perspectives on epidemiology, detection, and clinical challenges of inhalant abuse and offers advice regarding the medical and mental health providers' roles in the prevention and management of this substance abuse problem. Also discussed is the misuse of a specific "over-the-counter" dissociative, dextromethorphan. Copyright © 2016 Elsevier Inc. All rights reserved.

The previous researchers have postulated that an abused child may abuse his or her abuser parent when the parent is getting old, also known as the intergenerational transmission of violence. However, few studies use data to support this model, and it has yet to be examined in the U.S. Chinese community. This study aims to examine the association between childhood abuse and elder abuse reported by Chinese adult children in the United States. Guided by a community-based participatory research approach, 548 Chinese adult children aged 21 years and older participated in this study. Childhood abuse was assessed by four-item Hurt-Insult-Threaten-Scream (HITS) scale. Elder abuse was assessed by a 10-item instrument derived from the Caregiver Abuse Screen (CASE). Logistic regression analysis was performed. Childhood abuse was associated with caregiver abuse screen results (odds ratio = 1.92, 95% confidence interval = 1.24-2.95). Being physically hurt (r = .13, p < .01), insulted (r = .15, p < .001), threatened (r = .12, p < .01), and screamed at (r = .18, p < .001) as a child were significantly correlated with caregiver abuse screen results. This study suggests that childhood abuse is associated with increased risk of elder abuse among Chinese adult children in the United States. Longitudinal research should be conducted to explore the mechanisms through which childhood abuse and its subtypes links with elder abuse. © The Author 2017.

Substance abuse and child maltreatment.

PubMed

Wells, Kathryn

2009-04-01

Pediatricians and other medical providers caring for children need to be aware of the dynamics in the significant relationship between substance abuse and child maltreatment. A caregiver's use and abuse of alcohol, marijuana, heroin, cocaine, methamphetamine, and other drugs place the child at risk in multiple ways. Members of the medical community need to understand these risks because the medical community plays a unique and important role in identifying and caring for these children. Substance abuse includes the abuse of legal drugs as well as the use of illegal drugs. The abuse of legal substances may be just as detrimental to parental functioning as abuse of illicit substances. Many substance abusers are also polysubstance users and the compounded effect of the abuse of multiple substances may be difficult to measure. Often other interrelated social features, such as untreated mental illness, trauma history, and domestic violence, affect these families.

Child sexual abuse, attachment style, and depression: the role of the characteristics of abuse.

PubMed

Cantón-Cortés, David; Cortés, María Rosario; Cantón, José

2015-02-01

The aim of the current study was to examine the effects of secure, avoidant, and anxious attachment styles on depressive symptomatology in child sexual abuse (CSA) among young female adult victims. The role of attachment style was studied by considering possible interactive effects with the type of abuse, the relationship with the perpetrator, and the continuity of abuse. Participants were 168 female victims of CSA. Information about the abuse was obtained from a self-reported questionnaire. Attachment style was assessed with the Attachment Style Measure (ASM), and the Beck Depression Inventory (BDI) was used to assess depressive symptomatology. Secure and anxious attachment styles were correlated with low and high depression scores respectively. The effects of attachment style were stronger in cases where the abuse consisted of oral sex/penetration, a non-family member as perpetrator, and in isolated, compared with continued, abuse. These results confirm that characteristics of CSA (type of abuse, relationship with the perpetrator, and continuity of abuse) can affect the impact of attachment style on depressive symptomatology. © The Author(s) 2014.

Domestic abuse awareness and recognition among primary healthcare professionals and abused women: a qualitative investigation.

To investigate the dynamics of domestic abuse awareness and recognition among primary healthcare professionals and abused women. Domestic abuse is a serious, public health issue that crosses geographical and demographic boundaries. Health professionals are well placed to recognise and respond to domestic abuse, but empirical evidence suggests that they are reluctant to broach the issue. Moreover, research has shown that women are reluctant to disclose abuse. A two-phase, qualitative study was conducted in Scotland. Twenty-nine primary health professionals (midwives, health visitors and general practitioners) participated in the first phase of the study, and 14 abused women took part in phase two. Data were collected in 2011. Semi-structured, individual interviews were conducted with the health professionals, and three focus groups were facilitated with the abused women. Data were analysed using a framework analysis approach. Differing levels of awareness of the nature and existence of abuse are held by abused women and primary healthcare professionals. Specifically, many women do not identify their experiences as abusive. A conceptual representation of domestic abuse - the "abused women, awareness, recognition and empowerment' framework - arising from the study - presents a new way of capturing the complexity of the disclosure process. Further research is necessary to test and empirically validate the framework, but it has potential pedagogical use for the training and education of health professionals and clinical use with abused women. The framework may be used in clinical practice by nurses and other health professionals to facilitate open discussion between professionals and women. In turn, this may empower women to make choices regarding disclosure and safety planning. © 2014 John Wiley & Sons Ltd.

Abusive families and character formation.

PubMed

McCarthy, J B

1990-06-01

Family research studies confirm that abusive parents tend to be undifferentiated partners who compete with each other and with their children for attention and nurturance. More or less healthy parents make demands on children to counteract their own injured narcissism, but they do so largely without devaluation and the sadistic use of projective identification. Under sufficient stress abusive parents attack the child who fails to gratify their needs, thereby giving vent to longstanding frustrations and feelings of being threatened by the child's individuation and competency. The emotional atmosphere in such families facilitates ego deficits like those of the borderline personality as it molds the child's efforts to avoid anxiety. Devaluation, loss, and defenses against mourning partially account for depression and paranoid traits in abused youngsters. Early neglect and abuse exposes them to influential models who act out rage and primitive defenses. Some abused individuals project their rage and later become paranoid or antisocial, whereas others fragment or retain infantile defenses. The destructiveness of severe psychological abuse lies in the constriction of the experiencing self and healthy character development, together with the conditioning to repeat abusive relationships and to avoid intimacy. Achieving individuation under these circumstances entails overcoming the internalized abusive relationships and relinquishing the unconscious wish to be transformed from the abused into the abuser.

Relationships between parental alcohol abuse and social support, peer substance abuse risk and social support, and substance abuse risk among South Korean adolescents.

This study examined the roles played by parental alcohol abuse and social support, peer substance abuse risk and social support, and substance abuse risk among adolescents in South Korea. Participants were adolescents between the ages of 15 and 22 years (mean, 18), residing in Seoul city and in surrounding Kyung-gi Province. Of 259 participants, 41.3% scored 2 or more on the POSIT scale, which suggested they met the problematic criteria for substance abuse risk. Logistic regression results suggested that the influence of social support on substance abuse risk among adolescents depended on the source of support--parents or peers. These findings need to be considered in the development of intervention programs for adolescents at risk for substance abuse.

Purpose With ethical requirements to the enrollment of lower risk subjects, osteoporosis trials are underpowered to detect reduction in hip fractures. Different skeletal sites have different levels of fracture risk and response to treatment. We sought to identify fracture sites which cluster with hip fracture at higher than expected frequency; if these sites respond to treatment similarly, then a composite fracture endpoint could provide a better estimate of hip fracture reduction. Methods Cohort study using Veterans Affairs and Medicare administrative data. Male Veterans (n=5,036,536) aged 50-99 years receiving VA primary care between1999-2009 were included. Fractures were ascertained using ICD9 and CPT codes and classified by skeletal site. Pearson correlation coefficients, logistic regression and kappa statistics, were used to describe the correlation between each fracture type and hip fracture within individuals, without regards to the timing of the events. Results 595,579 (11.8%) men suffered 1 or more fractures and 179,597 (3.6%) suffered 2 or more fractures during the time under study. Of those with one or more fractures, rib was the most common site (29%), followed by spine (22%), hip (21%) and femur (20%). The fracture types most highly correlated with hip fracture were pelvic/acetabular (Pearson correlation coefficient 0.25, p<0.0001), femur (0.15, p<0.0001), and shoulder (0.11, p<0.0001). Conclusions Pelvic, acetabular, femur, and shoulder fractures cluster with hip fractures within individuals at greater than expected frequency. If we observe similar treatment risk reductions within that cluster, subsequent trials could consider use of a composite endpoint to better estimate hip fracture risk. PMID:26151123

Purpose The purpose of this paper is to provide a review of the current literature uncovering specific factors associated with self-harm and suicidality among young Asian American women, as well as to present the Fractured Identity Model as a framework for understanding these factors. This paper offers concrete suggestions for the development of culturally competent interventions to target suicidality, substance abuse, and mental illness among young Asian American women. Design/methodology/approach Empirical studies and theory-based papers featured in peer-reviewed journals between 1990 and 2014 were identified through scholarly databases, such as PubMed, MEDLINE, PsycINFO, JSTOR, and Google Scholar. Findings We identified several factors associated with suicidality among young Asian American women: (1) family dynamics, or having lived in a household where parents practice “disempowering parenting styles,” (2) substance use/abuse, and (3) untreated mental illness(es), which are exacerbated by the stigma and shame attached to seeking out mental health services. The Fractured Identity Model by Hahm et al. (2014) is presented as a possible pathway from disempowering parenting to suicidal and self-harm behaviors among this population, with substance abuse playing a significant mediating role. Research limitations/implications – Our review focused on Asian American women, substance use among Asian Americans, and mental health among Asian Americans. Literature that focused on Asians living in Asia or elsewhere outside of the USA was excluded from this review; the review was limited to research conducted in the USA and written in the English language. Practical implications The complex interplay among Asian American culture, family dynamics, gender roles/expectations, and mental health justifies the development of a suicide and substance abuse intervention that is tailored to the culture- and gender-specific needs of Asian Pacific Islander young women.

During laser treatment for tattoo removal, pigment chromophores absorb laser energy, resulting in fragmentation of the ink particles via selective photothermolysis. The present study aimed to outline macroscopic laser-tattoo interactions in tissue-mimicking (TM) phantoms treated with picosecond- and nanosecond-domain lasers. Additionally, high-speed cinematographs were captured to visualize time-dependent tattoo-tissue interactions, from laser irradiation to the formation of photothermal and photoacoustic injury zones (PIZs). In all experimental settings using the nanosecond or picosecond laser, tattoo pigments fragmented into coarse particles after a single laser pulse, and further disintegrated into smaller particles that dispersed toward the boundaries of PIZs after repetitive delivery of laser energy. Particles fractured by picosecond treatment were more evenly dispersed throughout PIZs than those fractured by nanosecond treatment. Additionally, picosecond-then-picosecond laser treatment (5-pass-picosecond treatment + 5-pass-picosecond treatment) induced greater disintegration of tattoo particles within PIZs than picosecond-then-nanosecond laser treatment (5-pass-picosecond treatment + 5-pass-nanosecond treatment). High-speed cinematography recorded the formation of PIZs after repeated reflection and propagation of acoustic waves over hundreds of microseconds to a few milliseconds. The present data may be of use in predicting three-dimensional laser-tattoo interactions and associated reactions in surrounding tissue.

Osteoporosis was found to be significantly associated with pelvic insufficiency fractures (p=0.003), as was hypertension (p=0.036), diabetes (p=0.021), vitamin D deficiency (p=0.004), hypocalcaemia (p=0.002) and nicotine abuse (p=0.0012) after adjustment for possible confounders in the multivariate linear regression analysis. Comparing the autonomous state before and after pelvic fracture, a high loss of autonomy was observed. Patients needing daily assistance nearly doubled their number. Overall mortality was high (20%). In conclusion, this study showed multiple risk factors for pelvic insufficiency fractures. Some, like vitamin D deficiency, can benefit easy preventive measures. Outcome of conservative therapy is poor, with loss of social and physical independence and autonomy. The mortality rate is high. Efforts should be made in preventing pelvic insufficiency fractures. All patients should be treated for the severe osteoporosis being associated with these fracture type. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Multiwell fracturing experiments. [Nitrogen foam fracture treatment

DOE Office of Scientific and Technical Information (OSTI.GOV)

Warpinski, N.

The objective of the Multiwell fracturing experiments is to test and develop the technology for the efficient stimulation of tight, lenticular gas sands. This requires basic understanding of: (1) fracture behavior and geometry in this complex lithologic environment, and (2) subsequent production into the created fracture. The intricate interplay of the hydraulic fracture with the lens geometry, the internal reservoir characteristics (fractures, reservoir breaks, etc.), the in situ stresses, and the mechanical defects (fracture, bedding, etc.) need to be defined in order to develop a successful stimulation program. The stimulation phase of the Multiwell Experiment is concerned with: (1) determiningmore » important rock/reservoir properties that influence or control fracture geometry and behavior, (2) designing fracture treatments to achieve a desired size and objectives, and (3) conducting post-treatment analyses to evaluate the effectiveness of the treatment. Background statement, project description, results and evaluation of future plans are presented. 5 refs., 2 figs., 2 tabs.« less

Mimics of child abuse: Can choking explain abusive head trauma?

PubMed

Edwards, George A

2015-10-01

Choking is one of the alternative explanations of abusive head trauma in children that have been offered in courtroom testimony and in the media. Most of these explanations - including choking - are not scientifically supported. This article highlights four points. (1) The origins of choking as an explanation for intracranial and retinal hemorrhages are speculative. (2) Choking has been used in high profile court testimony as an explanation for the death of a child thought to have been abused. (3) A case report that proposes choking as an alternative explanation for the death of a child diagnosed with abusive head trauma includes omissions and misrepresentations of facts. (4) There was a decision by the editor of the journal that published the case report that it was not necessary to include all the facts of the case; moreover, the editor indicated that facts are not required when presenting an alternative explanation. The use of scientifically unsupported alternative explanations for abusive head trauma based on inaccurate and biased information constitutes further victimization of the abused child and represents a travesty of justice.

Clinical and Histologic Mimickers of Celiac Disease.

PubMed

Kamboj, Amrit K; Oxentenko, Amy S

Celiac disease is an autoimmune disorder of the small bowel, classically associated with diarrhea, abdominal pain, and malabsorption. The diagnosis of celiac disease is made when there are compatible clinical features, supportive serologic markers, representative histology from the small bowel, and response to a gluten-free diet. Histologic findings associated with celiac disease include intraepithelial lymphocytosis, crypt hyperplasia, villous atrophy, and a chronic inflammatory cell infiltrate in the lamina propria. It is important to recognize and diagnose celiac disease, as strict adherence to a gluten-free diet can lead to resolution of clinical and histologic manifestations of the disease. However, many other entities can present with clinical and/or histologic features of celiac disease. In this review article, we highlight key clinical and histologic mimickers of celiac disease. The evaluation of a patient with serologically negative enteropathy necessitates a carefully elicited history and detailed review by a pathologist. Medications can mimic celiac disease and should be considered in all patients with a serologically negative enteropathy. Many mimickers of celiac disease have clues to the underlying diagnosis, and many have a targeted therapy. It is necessary to provide patients with a correct diagnosis rather than subject them to a lifetime of an unnecessary gluten-free diet.

Many adult survivors of childhood abuse hide their victimization, avoiding disclosure that could identify perpetrators, end the abuse, and bring help to the victim. We surveyed 1,679 women undergraduates to understand disclosure of childhood sexual, physical, and emotional abuse, and, for the first time, witnessed domestic violence, which many consider to be emotionally abusive. A substantial minority of victims failed to ever disclose their sexual abuse (23%), physical abuse (34%), emotional abuse (20%), and witnessed domestic violence (29%). Overall, abuse-specific factors were better predictors of disclosure than individual-level characteristics. Disclosure of sexual abuse was related to experiencing more frequent abuse (by the same and by multiple perpetrators), being more worried about injury and more upset at the time of the abuse, and self-labeling as a victim of abuse. Disclosure of physical abuse was related to experiencing more frequent abuse (by the same and multiple perpetrators), being less emotionally close to the perpetrator, being older when the abuse ended, being more worried and upset, and self-labeling as a victim. Disclosure of emotional abuse was associated with being older when the abuse ended, and being more worried and upset. Disclosure was unrelated to victim demographic characteristics or defensive reactions (dissociative proneness, fantasy proneness, repressive coping style, and temporary forgetting), except that among physical and emotional abuse victims, repressors were less likely to disclose than non-repressors. Disclosure of witnessing domestic violence was not significantly related to any factors measured. © The Author(s) 2014.

An opportunity exists today for cross-cutting research utilizing advances in materials science, immunology, microbial pathogenesis, and computational analysis to effectively design the next generation of adjuvants and vaccines. This study integrates these advances into a bottom-up approach for the molecular design of nanoadjuvants capable of mimicking the immune response induced by a natural infection but without the toxic side effects. Biodegradable amphiphilic polyanhydrides possess the unique ability to mimic pathogens and pathogen associated molecular patterns with respect to persisting within and activating immune cells, respectively. The molecular properties responsible for the pathogen-mimicking abilities of these materials have been identified. The value of using polyanhydride nanovaccines was demonstrated by the induction of long-lived protection against a lethal challenge of Yersinia pestis following a single administration ten months earlier. This approach has the tantalizing potential to catalyze the development of next generation vaccines against diseases caused by emerging and re-emerging pathogens.

Foals are susceptible to many of the same types of fractures as adult horses, often secondary to external sources of trauma. In addition, some types of fractures are specific to foals and occur routinely in horses under 1 year of age. These foal-specific fractures may be due to the unique musculoskeletal properties of the developing animal and may present with distinct clinical signs. Treatment plans and prognoses are tailored specifically to young animals. Common fractures not affecting the long bones in foals are discussed in this article, including osteochondral fragmentation, proximal sesamoid bone fractures/sesamoiditis, and distal phalanx fractures.

The aim of this study was to examine the difference of early maladaptive schemas and parenting origins in opioid abusers and non-opioid abusers. The early maladaptive schemas and parenting origins were compared in 56 opioid abusers and 56 non-opioids abusers. Schemas were assessed by the Young Schema Questionnaire 3rd (short form); and parenting origins were assessed by the Young Parenting Inventory. Data were analyzed by multivariate analysis of variance (MANOVA). The analysis showed that the means for schemas between opioid abusers and non-opioid abusers were different. Chi square test showed that parenting origins were significantly associated with their related schemas. The early maladaptive schemas and parenting origins in opioid abusers were more than non-opioid abusers; and parenting origins were related to their Corresponding schemas.

The present study builds on research to model abusers' perceptions of particular analgesics' attractiveness for abuse and extends these methods to derive an estimate of attractiveness for abuse of a not-yet-marketed abuse-deterrent formulation (ADF) of a prescription opioid (Remoxy), Pain Therapeutics, Inc., San Mateo, CA, and King Pharmaceuticals, Inc., Bristol, TN). In a previous study, the Opioid Attractiveness Technology Scaling (OATS) method identified, from a drug abuser's point of view, the particular features of a prescription opioid relevant to its attractiveness for recreational use. A second online sample rated the extent to which these features applied to particular products they had actually used/abused. These data were used to model the abusers' overall preference for prescription opioids they had used/abused. In the present study, this method was applied to a not-yet-marketed ADF using substance abuse counselors as proxies for prescription opioid abusers. Thirty-eight counselors were given materials describing the new ADF along with four known products. Thirty-two counselors demonstrated sufficient agreement with abusers' ratings of the overall attractiveness of these drugs. The overall model yielded a significant pseudo R(2) of 0.15 (P < 0.001), with increasing model fit based on preferred route of administration, from swallowing whole (pseudo R(2) = 0.06; P < 0.001) and best for those who preferred to inject (pseudo R(2) = 0.40; P < 0.001). Data from a cross-validation group of 16 counselors/proxies were used to calculate the OATS scores for the five rated drugs and revealed significant differences between the ADF and OxyContin (Purdue Pharma LP, Stamford, CT), Percocet (Endo Pharmaceuticals, Chadds Ford, PA), and Vicodin (Abbott Laboratories, Abbott Park, IL), but not Talwin NX (Sanofi-aventis, Bridgewater, NJ), which was identified in the prior study as a highly unattractive drug for recreational purposes. The OATS method shows promise for

Alcohol and drug abuse are detrimental to general and oral health. Though we know the effects of these harmful habits on oral mucosa, their independent and combined effect on the dental caries experience is unknown and worthy of investigation. We compared 363 “alcohol only” abusers to 300 “alcohol and drug” abusers to test the hypothesis that various components of their dental caries experience are significantly different due to plausible sociobiological explanations. After controlling for the potential confounders, we observe that the “alcohol and drug” group had a 38% higher risk of having decayed teeth compared to the “alcohol only” group (P < .05). As expected, those who belonged to a higher social class (OR = 1.98; 95%  CI = 1.43–2.75) and drank wine (OR = 1.85; 95%  CI = 1.16–2.96) had a higher risk of having more filled teeth. We conclude that the risk of tooth decay among “alcohol only” abusers is significantly lower compared to “alcohol and drug” abusers. PMID:20379366

It has been shown earlier that there is a rise in the levels of autoantibodies and T cell response to cytoskeletal proteins in leprosy. Our group recently demonstrated a rise in both T and B cell responses to keratin and myelin basic protein in all types of leprosy patients and their associations in type 1 reaction (T1R) group of leprosy. In this study, we investigated the association of levels of autoantibodies and lymphoproliferation against myosin in leprosy patients across the spectrum and tried to find out the mimicking proteins or epitopes between host protein and protein/s of Mycobacterium leprae . One hundred and sixty-nine leprosy patients and 55 healthy controls (HC) were enrolled in the present study. Levels of anti-myosin antibodies and T-cell responses against myosin were measured by ELISA and lymphoproliferation assay, respectively. Using 2-D gel electrophoresis, western blot and MALDI-TOF/TOF antibody-reactive spots were identified. Three-dimensional structure of mimicking proteins was modeled by online server. B cell epitopes of the proteins were predicted by BCPREDS server 1.0 followed by identification of mimicking epitopes. Mice of inbred BALB/c strain were hyperimmunized with M. leprae soluble antigen (MLSA) and splenocytes and lymph node cells of these animals were adoptively transferred to naïve mice. Highest level of anti-myosin antibodies was noted in sera of T1R leprosy patients. We observed significantly higher levels of lymphoproliferative response ( p  < 0.05) with myosin in all types of leprosy patients compared to HC. Further, hyperimmunization of inbred BALB/c strain of female mice and rabbit with MLSA revealed that both hyperimmunized rabbit and mice evoked heightened levels of antibodies against myosin and this autoimmune response could be adoptively transferred from hyperimmunized to naïve mice. Tropomyosin was found to be mimicking with ATP-dependent Clp protease ATP-binding subunit of M. leprae . We found four mimicking

Understanding elder abuse in family practice

Abstract Objective To discuss what constitutes elder abuse, why family physicians should be aware of it, what signs and symptoms might suggest mistreatment of older adults, how the Elder Abuse Suspicion Index might help in identification of abuse, and what options exist for responding to suspicions of abuse. Sources of information MEDLINE, PsycINFO, and Social Work Abstracts were searched for publications in English or French, from 1970 to 2011, using the terms elder abuse, elder neglect, elder mistreatment, seniors, older adults, violence, identification, detection tools, and signs and symptoms. Relevant publications were reviewed. Main message Elder abuse is an important cause of morbidity and mortality in older adults. While family physicians are well placed to identify mistreatment of seniors, their actual rates of reporting abuse are lower than those in other professions. This might be improved by an understanding of the range of acts that constitute elder abuse and what signs and symptoms seen in the office might suggest abuse. Detection might be enhanced by use of a short validated tool, such as the Elder Abuse Suspicion Index. Conclusion Family physicians can play a larger role in identifying possible elder abuse. Once suspicion of abuse is raised, most communities have social service or law enforcement providers available to do additional assessments and interventions. PMID:23242889

The aim of the present study was to determine the head, face and neck injuries associated with child abuse cases in the Cape Peninsula, Cape Town. South Africa. A retrospective, record-based analysis (n = 300) of non-accidental injuries at a Children's Hospital over a 5-year period (1992-1996) was carried out. The mean age of the sample was 4.75 years--54.3% were boys and 45.7% were girls. Most of the crimes were committed in the child's own home (88.7%). Crimes were reported by mothers (48.7%), grandmothers (11.7%) and day hospitals (13%). Ninety percent of the perpetrators were known to the victim. The majority of the perpetrators were male (79%)--20% the perpetrators were the mother's boyfriend; 36% the father or step father, and in 12% the mother was responsible. Thirty-five percent of perpetrators were under the influence of alcohol or drugs when they committed the offence: 64.7% of cases suffered serious injuries, 48.7% had to be hospitalized, four children were critically injured and died. The head, face, neck, and mouth were the sites of physical injury in 67% of the 300 cases reviewed. The face was the most frequently injured (41%) part of the body, with the cheek being the most common site for the injury. The range and diversity of the oro-facial injuries included skull fractures, subdural hematomas, retinal hemorrhages, bruises, burns, and lacerations. Injuries to the mouth included fractured teeth, avulsed teeth, lacerations to the lips, frenum, tongue, and jaw fractures. The main conclusions of this study were (i) under 2-year-old children were most at risk from abuse (36%); (ii) the number of the reported injuries to the oral cavity was extremely low (11%); and (iii) no dentists participated in the examination of any of the patients. Intra-oral injuries may be overlooked because of the medical examiner's unfamiliarity with the oral cavity. Oral health professionals should be consulted for diagnosis, advice and treatment.

Investigation of the Effect of Cemented Fractures on Fracturing Network Propagation in Model Block with Discrete Orthogonal Fractures

NASA Astrophysics Data System (ADS)

Wang, Y.; Li, C. H.

2017-07-01

Researchers have recently realized that the natural fractures in shale reservoirs are often cemented or sealed with various minerals. However, the influence of cement characteristics of natural fracture on fracturing network propagation is still not well understood. In this work, laboratory-scaled experiments are proposed to prepare model blocks with discrete orthogonal fractures network with different strength of natural fracture, in order to reveal the influence of cemented natural fractures on the interactions between hydraulic fractures and natural fractures. A series of true triaxial hydraulic fracturing experiments were conducted to investigate the mechanism of hydraulic fracture initiation and propagation in model blocks with natural fractures of different cement strength. The results present different responses of interactions between hydraulic and natural fractures, which can be reflected on the pump pressure profiles and block failure morphology. For model blocks with fluctuated pump pressure curves, the communication degree of hydraulic and natural fractures is good, which is confirmed by a proposed new index of "P-SRV." The most significant finding is that too high and too low strength properties of cemented natural fracture are adverse to generate complex fracturing network. This work can help us better understand how cemented natural fractures affect the fracturing network propagation subsurface and give us reference to develop more accurate hydraulic fracturing models.

Abuse of prescription drugs.

Wilford, B B

1990-01-01

An estimated 3% of the United States population deliberately misuse or abuse psychoactive medications, with severe consequences. According to the National Institute on Drug Abuse, more than half of patients who sought treatment or died of drug-related medical problems in 1989 were abusing prescription drugs. Physicians who contribute to this problem have been described by the American Medical Association as dishonest--willfully misprescribing for purposes of abuse, usually for profit; disabled by personal problems with drugs or alcohol; dated in their knowledge of current pharmacology or therapeutics; or deceived by various patient-initiated fraudulent approaches. Even physicians who do not meet any of these descriptions must guard against contributing to prescription drug abuse through injudicious prescribing, inadequate safeguarding of prescription forms or drug supplies, or acquiescing to the demands or ruses used to obtain drugs for other than medical purposes.

Queen, Josie; Nurse, Army; Brackley, Margaret H; Williams, Gail B

2009-04-01

The purpose of this study was to explore and describe individual perceptions, meanings, and definitions of emotional abuse through the lived experience of women who identified themselves as being emotionally abused by an intimate partner (IP). To answer the research question, "What is it like to live the life of a woman who is emotionally abused by her intimate partner?" A descriptive, phenomenological research design was undertaken. Unstructured individual interviews with 15 emotionally abused adult women resulted in the discovery of seven essential themes: captivity, defining moments, disassociation from self, fixing, mindful manipulation, relentless terror, and taking a stand. A combination of a hermeneutic approach and Diekelmann's approach to data analysis was used to explore differences in perceptions and develop essential themes that portrayed the essence of a woman's lived experience of being emotionally abused by her IP. The data also demonstrated that (1) IP emotional abuse has no prerequisite for partner rage or obvious emotional manipulation, (2) the absence of caring and respectful partner behaviors was just as powerful in creating an emotionally abusive experience as openly abusive behaviors, and (3) being emotionally abused was a life journey, encompassing multiple culminations, secondary physical and mental health symptoms, and quality of life issues that extended well beyond the immediate abuse experience.

Forensic and family psychiatry in abuse dwarfism: Munchausen's syndrome by proxy, atonement, and addiction to abuse.

PubMed

Money, J; Annecillo, C; Hutchison, J W

1985-01-01

The syndrome of abuse dwarfism is characterized by gross impairment of statural and intellectual growth and social maturation while the abused child remains in the domicile of abuse. The parents collude as child abusers, and are medical impostors regarding the symptoms of abuse. The syndrome as a whole is appropriately named Munchausen's syndrome by proxy. Though the mother typically initiates abuse, she cannot give a rational explanation for doing so. In her own history there is a sin that is expiated or atoned for symbolically by the sacrifice of the child--explainable in terms of the theory of opponent-process learning. In the two cases presented, the sin was the mother's own birth out of wedlock, in one case as a sequel to incest. The child's addiction to abuse is a challenge to the program of rehabilitation. With respect to parents at risk, the data of this paper are relevant to the prevention of a predisposition toward, or the actual implementation of child abuse, though a program of prevention needs still to be formulated. The sexological relevance of this paper is that the data demonstrate that the effects of sexual abuse may be transmitted to the next generation and manifested as child abuse which is not necessarily sexual in content.

Ballistic fractures: indirect fracture to bone.

PubMed

Dougherty, Paul J; Sherman, Don; Dau, Nathan; Bir, Cynthia

2011-11-01

Two mechanisms of injury, the temporary cavity and the sonic wave, have been proposed to produce indirect fractures as a projectile passes nearby in tissue. The purpose of this study is to evaluate the temporal relationship of pressure waves using strain gauge technology and high-speed video to elucidate whether the sonic wave, the temporary cavity, or both are responsible for the formation of indirect fractures. Twenty-eight fresh frozen cadaveric diaphyseal tibia (2) and femurs (26) were implanted into ordnance gelatin blocks. Shots were fired using 9- and 5.56-mm bullets traversing through the gelatin only, passing close to the edge of the bone, but not touching, to produce an indirect fracture. High-speed video of the impact event was collected at 20,000 frames/s. Acquisition of the strain data were synchronized with the video at 20,000 Hz. The exact time of fracture was determined by analyzing and comparing the strain gauge output and video. Twenty-eight shots were fired, 2 with 9-mm bullets and 26 with 5.56-mm bullets. Eight indirect fractures that occurred were of a simple (oblique or wedge) pattern. Comparison of the average distance of the projectile from the bone was 9.68 mm (range, 3-20 mm) for fractured specimens and 15.15 mm (range, 7-28 mm) for nonfractured specimens (Student's t test, p = 0.036). In this study, indirect fractures were produced after passage of the projectile. Thus, the temporary cavity, not the sonic wave, was responsible for the indirect fractures.

Large multi-centre studies of clavicle fractures have so far been missing. The aim of this observational study was to describe the epidemiology, classification and treatment of clavicle fractures in the The Swedish Fracture Register (SFR) that collects national prospective data from large fracture populations. Data were retrieved from the SFR on all clavicle fractures sustained by patients ≥ 15 years of age in 2013-2014 (n = 2 422) with regards to date of injury, cause of injury, fracture classification and treatment. Sixty-eight per cent of the clavicle fractures occurred in males. The largest subgroup was males aged 15-24 years, representing 21% of clavicle fractures. At the ages of 65 years and above, females sustained more clavicle fractures than males. Same-level falls and bicycle accidents were the most common injury mechanisms. Displaced midshaft fractures constituted 43% of all fractures and were the most frequently operated fractures. Seventeen per cent of the patients underwent operative treatment within 30 days of the injury, where plate fixation was the choice of treatment in 94% of fractures. The largest patient group was young males. Displaced midshaft fractures were the most common type of clavicle fracture as well as the most frequently operated type of fracture.

2007-12-01

Child abuse remains a significant problem in the United States with 2.9 million reports and 825 000 indicated cases in 2005. This report will highlight recent efforts toward child abuse prevention, focusing on home visiting programs, abusive head trauma primary prevention, parent training programs, sexual abuse prevention, and the effectiveness of laws banning corporal punishment. Most home visitation programs have demonstrated a lack of effectiveness in recent randomized trials. One exception is the Nurse Family Partnership, which remains the most effective and longest enduring intervention for high-risk families. Child sexual abuse prevention programs and parent training programs need further evaluation with more rigorous methodology and outcome measures. Providing universal parent education about coping with crying infants appears to be effective in lowering the incidence of abusive head trauma. Although advocated for, further study will determine the effectiveness of laws banning corporal punishment or mandating abusive head trauma education to parents of newborns. Pediatricians play an important role in the prevention of child maltreatment. Their knowledge of the effectiveness of different programs can help guide parents toward appropriate services.

The differential diagnosis of ritual abuse allegations.

PubMed

Bernet, W; Chang, D K

1997-01-01

Because psychiatrists do not have a consistent way to classify and define the forms of child abuse that may be mistaken for ritual abuse, the objective of this paper is to create a comprehensive differential diagnosis of allegations of ritual abuse. The authors reviewed 60 articles, chapters, and books that contained allegations of ritual abuse or behaviors that might be mistaken for ritual abuse, that were made by patients or caretakers. This paper clarifies the behaviors that represent or may be mistaken for ritual abuse: Cult-based ritual abuse, pseudoritualistic abuse, activities by organized satanic groups, repetitive psychopathological abuse, sexual abuse by pedophiles, child pornography portraying ritual abuse, distorted memory, false memory, false report due to a severe mental disorder, pseudologia phantastica, adolescent behavior simulating ritual abuse, epidemic hysteria, deliberate lying, and hoaxes. The differential diagnosis of allegations of ritual abuse is important in both clinical and forensic psychiatry. In some cases, it will not be possible to tell whether a particular allegation is factual or what the underlying mental processes are. It is important to separate the role of the mental health professional as therapist from the role as an expert witness in court.

2017-09-01

Depression and depressive symptoms have been studied both as risk factors and consequences of elder abuse, even though the most common cross-sectional design of the studies does not allow inferring cause or consequence relationships. This study estimates the proportion of older adults who screened positive for depressive symptoms among those self-reporting elder abuse and examines whether individual characteristics and/or abusive experience aspects are associated with self-reported depressive symptoms. Participants were 510 older adults self-reporting experiences of abuse in family setting enrolled in the cross-sectional victims' survey of the Aging and Violence Study. Depressive symptoms were assessed through the abbreviated version of the Geriatric Depression Scale (GDS-5). Poisson regression was used to determine the prevalence ratio (PR) of screening depressive symptoms according to individual and abusive experience covariates: sex, age group, cohabitation, perceived social support, chronic diseases, functional status, violence type, perpetrator, and number of conducts. Women (PR = 1.18, 95% confidence interval [CI] = [1.04, 1.35]) individuals perceiving low social support level (PR = 1.36, 95% CI = [1.16, 1.60]) and with long-term illness (PR = 1.17, 95% CI = [1.02, 1.33]) were found to be associated with increased risk for screening depressive symptoms. In regard to abusive experience, only the number of abusive conducts increased the PR (PR = 1.07, 95% CI = [1.05, 1.09]). Routine screening for elder abuse should include psychological well-being assessment. Interventions toward risk alleviation for both mental health problems and elder abuse should target women perceiving low social support level and with long-term illness.

Affective responsiveness, betrayal, and childhood abuse.

PubMed

Reichmann-Decker, Aimee; DePrince, Anne P; McIntosh, Daniel N

2009-01-01

Several trauma-specific and emotion theories suggest that alterations in children's typical affective responses may serve an attachment function in the context of abuse by a caregiver or close other. For example, inhibiting negative emotional responses or expressions might help the child preserve a relationship with an abusive caregiver. Past research in this area has relied on self-report methods to discover links between affective responsiveness and caregiver abuse. Extending this literature, the current study used facial electromyography to assess affective responsiveness with 2 measures: mimicry of emotional facial expressions and affective modulation of startle. We predicted that women who reported childhood abuse by close others would show alterations in affective responsiveness relative to their peers. We tested 100 undergraduate women who reported histories of (a) childhood sexual or physical abuse by someone close, such as a parent (high-betrayal); (b) childhood abuse by someone not close (low-betrayal); or (c) no abuse in childhood (no-abuse). Especially when viewing women's emotional expressions, the high-betrayal group showed more mimicry of happy and less mimicry of angry faces relative to women who reported no- or low-betrayal abuse, who showed the opposite pattern. Furthermore, women who reported high-betrayal abuse showed less affective modulation of startle during pictures depicting men threatening women than did the other two groups. Findings suggest that, as predicted by betrayal trauma theory, women who have experienced high-betrayal abuse show alterations in automatic emotional processes consistent with caregiving-maintenance goals in an abusive environment.

Abuse of elderly people by their carers.

Homer, A C; Gilleard, C

1990-01-01

OBJECTIVE--To assess the prevalence of abuse of elderly people by their carers and the characteristics of abusers and the abused. DESIGN--Information on abuse and risk factors was collected over six months from carers and patients. Risk factors were identified in the abused group and compared with those in a non-abused control group. SETTING--Carers were interviewed at home; patients were examined in the wards of Putney and Barnes geriatric hospitals, London. SUBJECTS--All patients referred from any source for respite care to the geriatric services over a six month period and their carers. MAIN OUTCOME MEASURES--Amount of physical and verbal abuse or neglect. Quantification of risk factors and correlation with the presence or absence of abuse. RESULTS--45% Of carers openly admitted to some form of abuse. Few patients admitted abuse. The most significant risk factor for physical abuse was alcohol consumption by the carer (p less than 0.001). Other significant risk factors were a poor pre-morbid relationship and previous abuse over many years. Abuse was often reciprocated and was associated with social dysfunction in many patients. Service delivery, respite care, and level of mental and physical disability were not significantly associated with abuse. CONCLUSION--The high level of abuse found in elderly patients in respite care was particularly associated with alcohol abuse and long term relationships of poor quality, which are difficult to change. Even with increased provision of services, care in the community may not be the best solution for these people. PMID:2271883

Sexual abuse is a problem of epidemic proportions in the United States. Given the sheer numbers of sexually abused children, it is vital for pediatric nurse practitioners to understand both short-term and long-term consequences of sexual abuse. Understanding consequences of sexual abuse can assist the pediatric nurse practitioner in anticipating the physical and mental health needs of patients and also may assist in the identification of sexual abuse victims. Sexual abuse typically does not occur in isolation. Implications for practice will be discussed. Copyright © 2010 National Association of Pediatric Nurse Practitioners. Published by Mosby, Inc.

The objective of this study is to carry out a current survey of the situation of child abuse in the family. It is based on a national survey conducted in 1996, which was addressed to childcare professionals (in the areas of health, education and social services). This survey was based, on the one hand, on a wide-ranging definition of child abuse, including within it not just active forms of physical and psychic violence against the child, but also forms of (both material and affective) privation, omission or negligence which affect the child's growth and development. On the other hand, this study also favoured a contextual approach to child abuse. 1,126 institutions in Portugal were contacted and 755 valid survey responses were received. This report outlines some of the results obtained, namely by providing a description of the sample of the 755 child abuse victims, the respective social and family contexts to which they and the aggressors belong, as well as the types of abuse which have been committed against them; and a typology of forms of abuse and negligence, describing not just the internal aspects that make up child abuse directly, but also its relationship to the child's social and family contexts of belonging. The typology was derived from the statistical handling of the data gathered (factorial analysis of multiple matches, followed by a hierarchical analysis into clusters). A number of key concepts are summarised in the conclusion. Children of all age groups and of both sexes, and from all types of families and social backgrounds, regardless of their place in the phratry, are subject to abuse in Portugal. But different types of abuse and negligence are associated with the contexts to which the children and their families belong. Healthcare professionals are irreplaceable when it comes to detecting the wide variety of types of child abuse, and are an essential look-out post for two types of abuse which often slip through the net of other professionals

SU-F-T-433: Evaluation of a New Dose Mimicking Application for Clinical Flexibility and Reliability

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hoffman, D; Nair, C Kumaran; Wright, C

2016-06-15

Purpose: Clinical workflow and machine down time occasionally require patients to be temporarily treated on a system other than the initial treatment machine. A new commercial dose mimicking application provides automated cross-platform treatment planning to expedite this clinical flexibility. The aim of this work is to evaluate the feasibility of automatic plan creation and establish a robust clinical workflow for prostate and pelvis patients. Methods: Five prostate and five pelvis patients treated with helical plans were selected for re-planning with the dose mimicking application, covering both simple and complex scenarios. Two-arc VMAT and 7- and 9-field IMRT plans were generatedmore » for each case, with the objective function of achieving similar dose volume histogram from the initial helical plans. Dosimetric comparisons include target volumes and organs at risk (OARs) (rectum, bladder, small bowel, femoral heads, etc.). Dose mimicked plans were evaluated by a radiation oncologist, and patient-specific QAs were performed to validate delivery. Results: Overall plan generation and transfer required around 30 minutes of dosimetrist’s time once the dose-mimicking protocol is setup for each site. The resulting VMAT and 7- and 9-field IMRT plans achieved equivalent PTV coverage and homogeneity (D99/DRx = 97.3%, 97.2%, 97.2% and HI = 6.0, 5.8, and 5.9, respectively), compared to helical plans (97.6% and 4.6). The OAR dose discrepancies were up to 6% in rectum Dmean, but generally lower in bladder, femoral heads, bowel and penile bulb. In the context of 1–5 fractions, the radiation oncologist evaluated the dosimetric changes as not clinically significant. All delivery QAs achieved >90% pass with a 3%/3mm gamma criteria. Conclusion: The automated dose-mimicking workflow offers a strategy to avoid missing treatment fractions due to machine down time with non-clinically significant changes in dosimetry. Future work will further optimize dose mimicking plans and

The hyperplantarflexion variant ankle fracture is composed of a posterior tibial lip fracture with posterolateral and posteromedial fracture fragments separated by a vertical fracture line. This infrequently reported injury pattern often includes an associated "spur sign" or double cortical density at the inferomedial tibial metaphysis. The objective of this study was to quantitatively establish the association of the ankle fracture spur sign with the hyperplantarflexion variant ankle fracture. Our clinical database of operative ankle fractures was retrospectively reviewed for the incidence of hyperplantarflexion variant and nonvariant ankle fractures as determined by assessment of injury radiographs, preoperative advanced imaging, and intraoperative observation. Injury radiographs were then evaluated for the presence of the spur sign, and association between the spur sign and variant fractures was analyzed. The incidence of the hyperplantarflexion variant fracture among all ankle fractures was 6.7% (43/640). The spur sign was present in 79% (34/43) of variant fractures and absent in all nonvariant fractures, conferring a specificity of 100% in identifying variant fractures. Positive predictive value and negative predictive value were 100% and 99%, respectively. The ankle fracture spur sign was pathognomonic for the hyperplantarflexion variant ankle fracture. It is important to identify variant fractures preoperatively as patient positioning, operative approach, and fixation construct of variant fractures often differ from those employed for osteosynthesis of nonvariant fractures. Identification of the spur sign should prompt acquisition of advanced imaging to formulate an appropriate operative plan to address the variant fracture pattern.

Elder abuse is a pervasive phenomenon around the world with devastating effects on the victims. Although it is not a new phenomenon, interest in examining elder abuse is relatively new. This paper aims to provide an overview of the aetiological theories and measures of elder abuse. The paper briefly reviews theories to explain causes of elder abuse and then discusses the most commonly used measures of elder abuse. Based on the reviewed theories, it can be concluded that elder abuse is a multifactorial problem that may affect elderly people from different backgrounds and involve a wide variety of potential perpetrators, including caregivers, adult children, and partners. The review of existing measurement instruments notes that many different screening and assessment instruments have been developed to identify elders who are at risk for or are victims of abuse. However, there is a real need for more measurements of elder abuse, as the current instruments are limited in scope. © 2013 The Authors. Psychogeriatrics © 2013 Japanese Psychogeriatric Society.

Domestic violence is passed from one generation to the next, and it affects not only the victim but also the psychological states of the witnesses, and especially the psychosocial development of children. Studies have reported that those who have been the victim of or witnessing violence during their childhood will use violence to a greater extent as adults in their own families. This research examines the relationships between a history of childhood physical abuse, likelihood of psychiatric diagnoses, and potential for being a perpetrator of childhood physical abuse in adulthood among women who received psychiatric treatment and in the healthy population from Turkey. Estimates of the prevalence of childhood physical abuse vary depending on definition and setting. The frequency of witnessing and undergoing physical abuse within the family during childhood is much higher in the psychiatrically disordered group than the healthy controls. Childhood physical abuse history is one of the major risk factors for being an abuser in adulthood. The best indicator of physically abusing one's own children was found to be as physical abuse during the childhood period rather than psychiatric diagnosis. There is a large body of research indicating that adults who have been abused as children are more likely to abuse their own children than adults without this history. This is an important study from the point of view that consequences of violence can span generations. Further studies with different risk factor and populations will help to identify different dimensions of the problem.

In this study, multifunctional and heparin-mimicking star-shaped supramolecules-deposited 3D porous multilayer films with improved biocompatibility were fabricated via a layer-by-layer (LbL) self-assembly method on polymeric membrane substrates. Star-shaped heparin-mimicking polyanions (including poly(styrenesulfonate-co-sodium acrylate; Star-PSS-AANa) and poly(styrenesulfonate-co-poly(ethylene glycol)methyl ether methacrylate; Star-PSS-EGMA)) and polycations (poly(methyl chloride-quaternized 2-(dimethylamino)ethyl methacrylate; Star-PMeDMA) were first synthesized by atom transfer radical polymerization (ATRP) from β-cyclodextrin (β-CD) based cores. Then assembly of 3D porous multilayers onto polymeric membrane surfaces was carried out by alternating deposition of the polyanions and polycations via electrostatic interaction. The surface morphology and composition, water contact angle, blood activation, and thrombotic potential as well as cell viability for the coated heparin-mimicking films were systematically investigated. The results of surface ATR-FTIR spectra and XPS spectra verified successful deposition of the star-shaped supramolecules onto the biomedical membrane surfaces; scanning electron microscopy (SEM) and atomic force microscopy (AFM) observations revealed that the modified substrate had 3D porous surface morphology, which might have a great biological influence on the biointerface. Furthermore, systematic in vitro investigation of protein adsorption, platelet adhesion, human platelet factor 4 (PF4, indicates platelet activation), activate partial thromboplastin time (APTT), thrombin time (TT), coagulation activation (thrombin-antithrombin III complex (TAT, indicates blood coagulant)), and blood-related complement activation (C3a and C5a, indicates inflammation potential) confirmed that the heparin-mimicking multilayer coated membranes exhibited ultralow blood component activations and excellent hemocompatibility. Meanwhile, after surface coating

Clavicle fractures.

Management of clavicle fracture has progressed over the last decade, notably with wider use of surgery in midshaft fracture, and new techniques for lateral fracture. Midshaft clavicle fracture treatment needs to be personalized and adapted to the patient's activity level. Whichever the segment involved, treatment for non-displaced fracture is functional; elbow-to-body sling immobilization seems the best tolerated. Apart from regular surgical indications (shoulder impaction, floating shoulder, open fracture or fracture with neurovascular complications), surgery is recommended in case of bone shortening exceeding 1.5cm in young active patients. The technique needs to take account of clavicle anatomy: notably periosteal vascularization in midshaft fracture and acromioclavicular ligament integrity and location in case of lateral fracture. Plate osteosynthesis should take account of bone diameter and 3D curvature; intramedullary fixation should take account of intramedullary canal morphology. Although iatrogenic vascular complications are rare, vessel relations and variants need to be known, especially in the medial end of the clavicle and midshaft. Lateral segment fractures are a particular entity. Large-scale randomized studies are needed to assess indications and results for the various possible internal fixation techniques: isolated or associated to ligament reconstruction, rigid or flexible, and open or arthroscopic.

Child abuse and neglect have been associated with cognitive deficits, among other effects on child development. This study explores the prediction that child abuse and neglect has an impact on Stanford-Binet Intelligence Scales 5th Edition (SB5) IQ scores, in relation to gender, age and type of abuse experienced. 300 children with experiences of abuse and neglect were included in the study, comprising 100 sexually abused, 100 physically abused and 100 neglected children. Overall, all scores on the SB5 were found to be significantly lower than the minimum average scores on the test. Verbal IQ (VIQ) scores were likewise found to be significantly lower than Nonverbal IQ (NVIQ) scores. Full Scale IQ (FSIQ) scores did not reveal heterogeneity when gender was factored in. Age and type of abuse (with a moderate effect size) on the other hand, showed significant differences among groups. Statistical analyses of SB5 Factor Index Scores revealed that abused children, in general, have significantly higher Visual-Spatial Processing (VS) and Quantitative Reasoning (QR) scores and lower scores in Knowledge (KN). There was a large effect size found in such an analysis. Age (with a large effect size), gender and type of abuse (with moderate effect sizes) give significant variations to this obtained profile.

Stahl, Daniel; Ellington, Matthew; Brennan, Kindyle; Brennan, Michael

2017-04-01

To determine whether the presence of ipsilateral rib fractures affects the rate of a clavicle fracture being unstable (>100% displacement). A retrospective review from 2002-2013 performed at a single level 1 trauma center evaluated 243 midshaft clavicle fractures. Single Level 1 trauma center. These fractures were subdivided into those with ipsilateral rib fractures (CIR; n = 149) and those without ipsilateral rib fractures (CnIR; n = 94). The amount of displacement was measured on the initial injury radiograph and subsequent follow-up radiographs. Fractures were classified into either <100% displacement or >100% displacement, based on anteroposterior radiographs. Ipsilateral rib fractures were recorded based on which number rib was fractured and the total number of fractured ribs. One hundred sixteen (78%) of the CIR group and 51 (54%) of the CnIR group were found to have >100% displacement at follow-up (P = 0.0047). Seventy-two percent of the CIR group demonstrated progression from <100% to >100% displacement of the fracture compared with only 54% of the CnIR group (P < 0.05). The odds ratio for progression of the clavicle fracture to >100% was 4.08 (P = 0.000194) when ribs 1-4 were fractured and not significant for rib fractures 5-8 or 9-12. The presence of concomitant ipsilateral rib fractures significantly increases the rate of midshaft clavicle fractures being >100% displaced. In addition, a fracture involving the upper one-third of the ribs significantly increases the rate of the clavicle fracture being >100% displaced on early follow-up. Clavicle fractures with associated ipsilateral rib fractures tend to demonstrate an increased amount of displacement on follow-up radiographs compared with those without ipsilateral rib fractures.

2017-03-01

Extreme cardiovascular reactions to psychological stress have been associated with traumatic life experiences. Previous studies have focused on the occurrence or frequency of abuse rather than type of abuse. We examined how occurrence, frequency, and the type of abuse history are related to cardiovascular reactivity (CVR) to acute psychological stress. The study consisted of between group and continuous analyses to examine the association between occurrence, type, and frequency of abuse with cardiovascular reactions to acute psychological stress. Data from 64 participants were collected. Heart rate, systolic blood pressure, and diastolic blood pressure were measured at baseline and during a standard mental arithmetic stress task. Individuals who experienced abuse showed diminished CVR to acute psychological stress; this was driven specifically by the history of sexual abuse. Frequency of abuse did not relate to stress reactions. These findings accord with previous work suggesting a relationship between traumatic life experience and hypoarousal in physiological reactivity and extend previous findings by suggesting the relationship may be driven by sexual abuse.

Assessing abuse potential of new analgesic medications following market release: an evaluation of Internet discussion of tapentadol abuse.

Research on substance abusers in treatment suggests that tapentadol, a prescription analgesic, may have relatively low abuse potential. Messages posted by recreational drug abusers on online forums were examined for amount of discussion and endorsement for abuse of tapentadol and comparator drugs. Internet messages posted between January 1, 2011 and September 30, 2012 on seven drug-abuse web forums were evaluated. Proportions of posts and unique authors discussing tapentadol were compared with eight comparator compounds. Postcontent was coded to compare endorsement for abuse of tapentadol with two comparators, one drug with high desirability for abuse and one with low desirability for abuse. A total of 1,940,121 messages posted during the study period were copied from selected web forums. The proportion of all posts discussing tapentadol (proportion = 0.0003) was significantly lower than any of the comparator compounds (range of odds ratios from 16.6 to 104.3; P < 0.001). The proportion of unique authors was also lower. Posts coded for endorsement (N =  2,117) yielded an endorsement ratio (Ero) of 2.14 for tapentadol, which was significantly lower than the highly desirable for abuse oxymorphone (ERo = 5.08; P = 0.0011) and was as low as tramadol (ERo = 1.66), which has a long-established profile of low abuse and desirability for abuse. Recreational abusers posting on web forums appear to be less interested in abusing tapentadol when compared with other, selected prescription analgesics based on the amount of discussion (i.e., fewer posts and authors mentioning tapentadol). Endorsement of the product for abuse was also low. Wiley Periodicals, Inc.

Demodex folliculitis mimicking acute graft-vs-host disease.

Cotliar, Jonathan; Frankfurt, Olga

2013-12-01

Acute graft-vs-host disease (GVHD) typically requires high-dose systemic steroids as first-line treatment. Like drug eruptions, viral exanthema, and toxic erythema of chemotherapy, Demodex folliculitis is a clinical mimicker of acute GVHD and requires nonimmunosuppressive therapy. This case of Demodex folliculitis mimicking acute GVHD highlights the need for skin biopsy in patients who have undergone a stem cell transplant with eruptions on the head and neck. A 46-year-old white woman with a history of Fms-like tyrosine kinase 3 acute myeloid leukemia presented to the dermatology clinic with a 5-day history of a nonpruritic eruption on her face and neck 28 days after undergoing a double umbilical cord blood hematopoietic stem cell transplant (HSCT). Findings from the skin biopsy demonstrated a deep dermal lymphocytic infiltrate adjacent to follicular units along with an abundance of Demodex mites noted within the hair follicles consistent with Demodex folliculitis. Oral ivermectin, 12 mg, was given, and the eruption cleared within 24 hours. To our knowledge, this is only the fifth reported case of Demodex folliculitis following HSCT, but the first ever reported to be successfully treated with oral ivermectin. Demodex folliculitis should be added to the differential diagnosis of skin eruptions that arise after HSCT.

The Many Victims of Substance Abuse

PubMed Central

2007-01-01

Substance abuse is a complicated disorder and has far reaching consequences. The victims of substance abuse extend beyond the unfortunate ones suffering from this disorder and often include family and friends. Treatment options for substance abuse are many; however, positive outcomes are not always guaranteed. Many factors play into the potential for successful treatment. Some of these include the adherence and motivation of the substance abusing patients as well as patients' surrounding environments and support systems. In this article, we present a clinical case of opioid dependence and discuss various treatment options and modalities. We will discuss different variables that may maximize positive treatment outcomes. Also a review of the current literature regarding substance abuse treatment, psychotherapy with the drug abuser, and grief therapy should the substance abusing patient die for the surviving family members will be presented.

Fibromatosis of the breast, also known as a desmoid tumor, is extremely rare and most often appears as an aggressive lesion mimicking breast carcinoma. It lacks metastatic potential but can grow aggressively in a localized area. Ultrasonography often shows an irregular spiculated hypoechoic mass with posterior acoustic shadowing. We discuss a case of breast fibromatosis that presented as a painful palpable breast mass in a 32-year-old woman and mimicked an abscess in the sonogram. We found that this lesion displayed atypical sonographic features such as a heterogeneous echoic mass with an internal anechoic area. Copyright © 2015 Elsevier Inc. All rights reserved.

A variety of subdural pathologies that may mimic hematomas are reported in the literature. We aimed to identify the atypical clinical and radiologic presentations of subdural masses that may mimic subdural hematomas. A systematic review of MEDLINE and Embase was conducted independently by 2 reviewers to identify articles describing subdural hematoma mimickers. We also present a patient from our institution with a subdural pathology mimicking a subdural hematoma. We analyzed patient clinical presentations, underlying pathologies, radiologic findings, and clinical outcomes. We included 43 articles totaling 48 patients. The mean ± SD patient age was 55.7 ± 16.8 years. Of the 45 cases describing patient history, 13 patients (27%) had a history of trauma. The underlying pathologies of the 48 subdural collections were 10 metastasis (21%), 14 lymphoma (29%), 7 sarcoma (15%), 4 infectious (8%), 4 autoimmune (8%), and 9 miscellaneous (19%). Findings on computed tomography (CT) scan were 18 hyperdense (41%), 11 hypodense (25%), 9 isodense (20%), 3 isodense/hyperdense (7%), and 3 hypodense/isodense (7%). Thirty-four patients (71%) were treated surgically; among these patients, 65% had symptom resolution. Neither the pathology (P = 0.337) nor the management strategy (P = 0.671) was correlated with improved functional outcomes. Identification of atypical history and radiologic features should prompt further diagnostic tests, including magnetic resonance imaging (MRI), to elucidate the proper diagnosis, given that certain pathologies may be managed nonsurgically. A subdural collection that is hyperdense on CT scan and hyperintense on T2-weighted MRI, along with a history of progressive headache with no trauma, may raise the suspicion of an atypical subdural pathology.

Addressing elder abuse: the Waterloo restorative justice approach to elder abuse project.

PubMed

Groh, Arlene; Linden, Rick

2011-04-01

The Community Care Access Centre (CCAC) of Waterloo Region, in partnership with a number of other social service agencies, designed and implemented a restorative justice model applicable to older adults who have been abused by an individual in a position of trust. The project was very successful in building partnerships, as many community agencies came together to deal with the problem of elder abuse. The program also raised the profile of elder abuse in the community. However, despite intensive efforts, referrals to the restorative justice program were quite low. Because of this, the program moved to a new organizational model, the Elder Abuse Response Team (EART), which has retained the guiding philosophy of restorative justice but has broadened the mandate. The team has evolved into a conflict management system that has multiple points of entry for cases and multiple options for dealing with elder abuse. The team has developed a broad range of community partners who can facilitate referrals to the EART and also can help to provide an individualized response to each case. The transition to the EART has been successful, and the number of referrals has increased significantly. Copyright © Taylor & Francis Group, LLC

Hip fracture creates a worldwide morbidity, mortality and economic burden. After surgery, many patients experience long-term disability or die as a consequence of the fracture. A fracture is a major risk factor for a subsequent fracture, which may occur within a short interval. A literature search on post-fracture management of patients with hip fracture was performed on the Medline database. Key experts convened to develop a consensus document. Management of hip-fracture patients to optimize outcome after hospital discharge requires several stages of care co-ordinated by a multidisciplinary team from before admission through to discharge. Further studies that specifically assess prevention and post-fracture management of hip fracture are needed, as only one study to date has assessed an osteoporosis medication in patients with a recent hip fracture. Proper nutrition is vital to assist bone repair and prevent further falls, particularly in malnourished patients. Vitamin D, calcium and protein supplementation is associated with an increase in hip BMD and reduction in falls. Rehabilitation is essential to improve functional disabilities and survival rates. Fall prevention and functional recovery strategies should include patient education and training to improve balance and increase muscle strength and mobility. Appropriate management can prevent further fractures and it is critical that high-risk patients are identified and treated. To foster this process, clinical pathways have been established to support orthopaedic surgeons. Although hip fracture is generally associated with poor outcomes, appropriate management can ensure optimal recovery and survival, and should be prioritized after a hip fracture to avoid deterioration of health and prevent subsequent fracture.

The sexual abuse of a child or young person constitutes a major social and public health problem and there is recent evidence that intra-familial (IF) sexual abuses are more serious in their consequences than extra-familial (EF). However, there are no studies on this phenomenon in Portugal. Thus, the aim of the present study is to contribute to a better characterization of these types of abuses and to identify possible differences between IF and EF cases. A retrospective study was preformed based on medico-legal reports related to victims below the age of 18, suspected of being sexually abused (n = 764), corresponding to 67% of the total of observed sexual crimes. Results revealed that 34.9% of the abuses are IF and they show statistically significant differences when compared to EF cases. These are due to the following factors found in IF situations: a) lower victim age; b) closeness between victim and abuser; c) abusers with a higher rate of previous sexual abuse; d) sexual practices of reduced physical intrusion; e) decreased physical violence but increased emotional violence; f) greater delay between last abuse and the forensic exam; g) reduced number of injuries or biological evidence (none in the great majority of the cases). Results point out the existence of several characteristics in IF abuse that have been identified as factors that influence the severity of the abuse consequences. Among them are: a) lower victim age; b) greater proximity to the abuser; c) increased amount of emotional violence. These factors account for the reduced visibility of this kind of cases and therefore explain their delayed disclosure and diagnosis. The association of this fact with the reduced intrusiveness of this sort of practice and the consequent decrease in number of injuries and other evidence leads to a marked reduction of the number of cases where evidence of the abuse can be found by physical examination alone. The above aspects underlie the need of using different

The elder abuse is a major public health problem. In the world, almost 4 to 10% of people of more than 65 years would be abuse. The generalist practitioners report only 2% of the elder abuse. Furthermore, the evaluations of elder abuse screenings test found in the scientist literature were unsatisfactory. Evaluate the elder abuse screening capacities of the Vulnerability to abuse screen scale (VASS) in order to propose it to the doctors. VASS was translated in French. It's a quantitative and a forward-looking study whose the answers of people of more than 65 years old were analysed and compared in blind way to the answers of socials workers. 200 patients were included between March and May 2012 in the CHU of Cimiez, Nice. We found 104 patients in danger of abuse, 40 cases of abuse revealed by the socials workers, so 20% of abuses were reported by the gold standard. It means a sensibility of 90,9%, a specificity of 49,7% and a predictive value of 96,1% to a score of 1 to the test. The screening test VASS shown it useful to detect elder people in danger of abuse but a few discriminants and not adapted to patients who have cognitive pathologies. It's a screening tool usable by default, more sensitive than others tests in the scientist literature. However, these results ask the question of the useful of these tools of elder abuse screening in comparison with the education of doctors which made proofs of success in this subject.

The aim of this study is to retrospectively analyze the incidence of facial fractures along with age, gender predilection, etiology, commonest site, associated dental injuries, and any complications of patients operated in Craniofacial Unit of SDM College of Dental Sciences and Hospital. This retrospective study was conducted at the Department of OMFS, SDM College of Dental Sciences, Dharwad from January 2003 to December 2013. Data were recorded for the cause of injury, age and gender distribution, frequency and type of injury, localization and frequency of soft tissue injuries, dentoalveolar trauma, facial bone fractures, complications, concomitant injuries, and different treatment protocols.All the data were analyzed using statistical analysis that is chi-squared test. A total of 1146 patients reported at our unit with facial fractures during these 10 years. Males accounted for a higher frequency of facial fractures (88.8%). Mandible was the commonest bone to be fractured among all the facial bones (71.2%). Maxillary central incisors were the most common teeth to be injured (33.8%) and avulsion was the most common type of injury (44.6%). Commonest postoperative complication was plate infection (11%) leading to plate removal. Other injuries associated with facial fractures were rib fractures, head injuries, upper and lower limb fractures, etc., among these rib fractures were seen most frequently (21.6%). This study was performed to compare the different etiologic factors leading to diverse facial fracture patterns. By statistical analysis of this record the authors come to know about the relationship of facial fractures with gender, age, associated comorbidities, etc.

Post-pancreatitis Fat Necrosis Mimicking Carcinomatosis.

Smith, Joshua P; Arnoletti, J Pablo; Varadarajulu, Shyam; Morgan, Desiree E

2008-01-01

Acute pancreatitis can result in retroperitoneal fat necrosis, typically occurring in the peripancreatic region, with extension into the transverse mesocolon, omentum and mesenteric root. When evaluated with contrast enhanced computed tomography (CECT), acute peripancreatic post necrotic collections typically become lower in attenuation over time, and often appear as homogeneous fluid collections. Saponification as a complication of fat necrosis in patients with acute pancreatitis is a well recognized clinical entity. While retroperitonal fat necrosis is commonly seen on CECT, saponification is not a prominent imaging feature. We present a case of acute pancreatitis complicated by extensive saponification of fat throughout the retroperitoneum and peritoneal lining, mimicking carcinomatosis.

A pediatric case of Cogan's syndrome mimicking acute Lyme arthritis is described. A 12-year-old black boy was admitted to the pediatric service for presumed right knee septic arthritis. Symptoms included acute pain and swelling with decreased range-of-motion. Although the patient's right knee symptoms and positive Lyme serology were consistent with a diagnosis of Lyme arthritis, the presence of sensorineural hearing loss and interstitial keratitis with inflammatory arthritis suggested a diagnosis of Cogan's syndrome. Subsequent Western blot analysis was negative for Borrelia burgdorferi antigens. The patient had dramatic clinical improvement of musculoskeletal and ophthalmologic complaints shortly after receiving high-dose corticosteroids, although residual sensorineural hearing loss persisted.

To study second fracture at the same clavicle including prevalence, fracture configurations related to malunion types of the first fracture, and healing. Between 2008 and 2011, the authors reviewed medical records and radiographs of the clavicles of patients who sustained acute clavicular fractures from motorcycle accident. Second fracture at the same clavicle and prevalence were studied. Malunion of the first fracture of the same clavicle were typed and configurations of the second fracture at the same clavicles were described related to type of the malunion. There were 552 clavicular fractures. Four cases of which sustained a second fracture at the same clavicles. Malunion of the first clavicular fracture of the four cases were typed: type I, extension, type II, flexion, and type III, bayonet. There were one, two, and one case of second clavicular fractures of the type I, II, and III clavicular malunion. The configuration of second clavicular fracture of the type I malunion clavicle is located at lateral fragment, inferior displacement, and dorsal angulation with dorsal cortex conminution. The type II malunion clavicle is located at lateral fragment with minimal displacement. For the type III malunion clavicle, the second fracture is located at medial fragment with mild inferior displacement and inferior angulation. The four cases of the second fractures of the same clavicles healed within two months without complication. The prevalence of second fracture at the same clacicles was 7.2:1000. The three types of the first fracture malunion were extension, flexion, and bayonet. The configuration of the second fracture at the same clavicles depends on malunion types of the first clavicular fracture. They healed without complication.

The term "drug of abuse" is highly contextual. What constitutes a drug of abuse for one population of patients does not for another. It is therefore important to examine the needs of the patient population to properly assess the status of drugs of abuse. The focus of this article is on the bidirectional relationship between patients and drug abuse. In this paper we will introduce the dopaminergic systems of the brain in Parkinson's and the influence of antiparkinsonian drugs upon them before discussing this synergy of condition and medication as fertile ground for drug abuse. We will then examine the relationship between drugs of abuse and Parkinson's, both beneficial and deleterious. In summary we will draw the different strands together and speculate on the future merit of current drugs of abuse as treatments for Parkinson's disease. Copyright © 2015 Elsevier Inc.

Routes of abuse of prescription opioid analgesics: a review and assessment of the potential impact of abuse-deterrent formulations.

PubMed

Gasior, Maciej; Bond, Mary; Malamut, Richard

2016-01-01

Prescription opioid analgesics are an important treatment option for patients with chronic pain; however, misuse, abuse and diversion of these medications are a major global public health concern. Prescription opioid analgesics can be abused via intended and non-intended routes of administration, both intact or after manipulation of the original formulation to alter the drug-delivery characteristics. Available data indicate that ingestion (with or without manipulation of the prescribed formulation) is the most prevalent route of abuse, followed by inhalation (snorting, smoking and vaping) and injection. However, reported routes of abuse vary considerably between different formulations. A number of factors have been identified that appear to be associated with non-oral routes of abuse, including a longer duration of abuse, younger age, male sex and a rural or socially deprived location. The development of abuse-deterrent formulations of prescription opioid analgesics is an important step toward reducing abuse of these medications. Available abuse-deterrent formulations aim to hinder extraction of the active ingredient, prevent administration through alternative routes and/or make abuse of the manipulated product less attractive, less rewarding or even aversive. There are currently five opioid analgesics with a Food and Drug Administration abuse-deterrent label, and a number of other products are under review. A growing body of evidence suggests that introduction of abuse-deterrent opioid analgesics in the USA has been associated with decreased rates of abuse of these formulations. The availability of abuse-deterrent formulations therefore appears to represent an important step toward curbing the epidemic of abuse of prescription opioid analgesics, while ensuring the availability of effective pain medications for patients with legitimate medical need.

Child abuse, neglect and deprivation are more common than was previously thought. Family physicians are in a unique position to help abusers and abused because of their knowledge of patients from the cradle to the grave. They should use this knowledge to observe clues about parenting potential and should make a thorough family history a routine part of history taking in potential parents. They should also observe patients carefully during pregnancy and early childhood to detect parenting problems and to try to prevent all types of abuse, physical, mental and sexual. PMID:21267341

Altered-stress fracturing

DOE Office of Scientific and Technical Information (OSTI.GOV)

Warpinski, N.R.; Branagan, P.T.

Altered-stress fracturing is a concept whereby a hydraulic fracture in one well is reoriented by another hydraulic fracture in a nearby location. The application is in tight, naturally fractured, anisotropic reservoirs in which conventional hydraulic fractures parallel the highly permeable natural fractures and little production enhancement is achieved by conventional hydraulic fracturing. Altered-stress fracturing can modify the stress field so that hydraulic fractures propagate across the permeable natural fractures. A field test was conducted in which stress changes of 250 to 300 psi (1.7 to 2.1 MPa) were measured in an offset well 120 ft (37 m) away during relativelymore » small minifracs in a production well. These results show that stress-altered fracturing is possible at this site and others. Analytic and finite element calculations quantify the effects of layers, stresses, and crack size. Reservoir calculations show significant enhancement compared to conventional treatments. 21 refs., 12 figs., 3 tabs.« less

Facial fractures are infrequent in children and adolescents, and there are only few reports that review a significant number of patients. The objective of this study was to analyze the pattern of maxillofacial fractures in pediatric patients of Portugal. We reviewed the clinical records of a series of 1416 patients 18 years or younger with facial fractures, treated by the Department of Plastic Reconstructive, Aesthetic and of Maxillofacial Surgery of São João Hospital, Porto, Portugal, between 1993 and 2012. The following parameters were evaluated: age; sex; cause of the accident; hour, day, and month of hospital admission; location and type of fractures; presence and location of associated injuries; treatment methods; length of in-hospital stay; and complications. A total of 2071 fractures were treated. The ratio of boys to girls was 3.1:1. Patients between 16 and 18 years old were the major group (43.9%). Motor vehicle accident was the most common cause of injuries (48.7% of patients). Mandibular fractures were the most common (44.4%). Associated injuries occurred in 1015 patients (71.7%). Pediatric facial fractures are usually associated with severe trauma. There has been a highly significant decrease (P < 0.001) in pediatric facial fractures in Portugal for the past 20 years.

Child abuse has proved to be one of the most important social challenges. The present study attempts (a) to determine the prevalence of child abuse in an urban area in Iran and (b) to differentiate abused from non-abused adolescent boys using parental and child characteristics. A survey was conducted to determine the prevalence of different types of child abuse. The prevalence sample comprised 2,100 students selected through a multistage random sampling procedure. Data were collected using the Childhood Trauma Questionnaire (CTQ), Beck Depression Inventory, II (BDI-II), State Trait Anxiety Inventory (STAI), modified Hazan & Shaver Attachment Style Questionnaire (ASQ) and Symptom Check List 90 (SCL-90-R). Descriptive statistics and discriminant function analysis were used to analyze the data. The results showed that 14.85% of the subjects were exposed to child abuse, with emotional abuse being most prevalent (52.09%). Also, it appeared that variables such as parental depression and anxiety and children's attachment styles, anxiety, and aggression can help discriminate abused boys from their non-abused counterparts.

Anorectal manometry was performed in 40 women, who consulted for functional disorders of the lower gastrointestinal tract and had been sexually abused. Anismus, defined as a rise in anal pressure during straining, was observed in 39 of 40 abused women, but in only six of 20 healthy control women (P < 0.0001). Other parameters of anorectal manometry were compared with those observed in another control group composed of 31 nonabused women but with anismus, as well as the group of healthy controls. A decreased amplitude of anal voluntary contraction and an increased threshold volume in perception of rectal distension were observed in both abused and nonabused patients. A decreased amplitude of rectoanal inhibitory reflex, little rise in rectal pressure upon straining, frequent absence of initial contraction during rectal distension, and increased resting pressure at the lower part of the anal canal were observed in abused but not in nonabused patients, suggesting that these abnormalities, in association with anismus, suggest a pattern of motor activity in the anal canal that could be indicative of sexual abuse.

Mimicking the Moon

When Galileo first observed Venus displaying a crescent phase, he excitedly wrote to Kepler (in anagram) of Venus mimicking the moon-goddess. He would have been delirious with joy to see Saturn and Titan, seen in this image, doing the same thing. More than just pretty pictures, high-phase observations -- taken looking generally toward the Sun, as in this image -- are very powerful scientifically since the way atmospheres and rings transmit sunlight is often diagnostic of compositions and physical states. In this example, Titan's crescent nearly encircles its disk due to the small haze particles high in its atmosphere refracting the incoming light of the distant Sun. This view looks toward the sunlit side of the rings from about 3 degrees above the ringplane. The image was taken in violet light with the Cassini spacecraft wide-angle camera on Aug. 11, 2013. The view was obtained at a distance of approximately 1.1 million miles (1.7 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 154 degrees. Image scale is 64 miles (103 kilometers) per pixel. http://photojournal.jpl.nasa.gov/catalog/PIA18291

Behavioural consequences of child abuse

Abstract Objective To discuss the consequences of abuse on childhood behavioural development, to highlight some behavioural clues that might alert physicians to ongoing child abuse, and to explore the specific role of the family physician in this clinical situation. Sources of information A systematic search was used to review relevant research, clinical review articles, and child protection agency websites. Main message A child’s behaviour is an outward manifestation of inner stability and security. It is a lens through which the family physician can observe the development of the child throughout his or her life. All types of abuse are damaging to children—physically, emotionally, and psychologically—and can cause long-term difficulties with behaviour and mental health development. Family physicians need to be aware of and alert to the indicators of child abuse and neglect so that appropriate interventions can be provided to improve outcomes for those children. Conclusion Child abuse might cause disordered psychological development and behaviour problems. Family physicians have an important role in recognizing behaviour clues that suggest child abuse and in providing help to protect children. PMID:23946022

Relationships between fractures

Peacock, D. C. P.; Sanderson, D. J.; Rotevatn, A.

2018-01-01

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.

Proximal femoral fractures.

PubMed

Webb, Lawrence X

2002-01-01

Fractures of the proximal femur include fractures of the head, neck, intertrochanteric, and subtrochanteric regions. Head fractures commonly accompany dislocations. Neck fractures and intertrochanteric fractures occur with greatest frequency in elderly patients with a low bone mineral density and are produced by low-energy mechanisms. Subtrochanteric fractures occur in a predominantly strong cortical osseous region which is exposed to large compressive stresses. Implants used to address these fractures must be able to accommodate significant loads while the fractures consolidate. Complications secondary to these injuries produce significant morbidity and include infection, nonunion, malunion, decubitus ulcers, fat emboli, deep venous thrombosis, pulmonary embolus, pneumonia, myocardial infarction, stroke, and death.

Fracture mechanisms and fracture control in composite structures

NASA Astrophysics Data System (ADS)

Kim, Wone-Chul

Four basic failure modes--delamination, delamination buckling of composite sandwich panels, first-ply failure in cross-ply laminates, and compression failure--are analyzed using linear elastic fracture mechanics (LEFM) and the J-integral method. Structural failures, including those at the micromechanical level, are investigated with the aid of the models developed, and the critical strains for crack propagation for each mode are obtained. In the structural fracture analyses area, the fracture control schemes for delamination in a composite rib stiffener and delamination buckling in composite sandwich panels subjected to in-plane compression are determined. The critical fracture strains were predicted with the aid of LEFM for delamination and the J-integral method for delamination buckling. The use of toughened matrix systems has been recommended for improved damage tolerant design for delamination crack propagation. An experimental study was conducted to determine the onset of delamination buckling in composite sandwich panel containing flaws. The critical fracture loads computed using the proposed theoretical model and a numerical computational scheme closely followed the experimental measurements made on sandwich panel specimens of graphite/epoxy faceskins and aluminum honeycomb core with varying faceskin thicknesses and core sizes. Micromechanical models of fracture in composites are explored to predict transverse cracking of cross-ply laminates and compression fracture of unidirectional composites. A modified shear lag model which takes into account the important role of interlaminar shear zones between the 0 degree and 90 degree piles in cross-ply laminate is proposed and criteria for transverse cracking have been developed. For compressive failure of unidirectional composites, pre-existing defects play an important role. Using anisotropic elasticity, the stress state around a defect under a remotely applied compressive load is obtained. The experimentally

Attributions of Blame in a Hypothetical Child Sexual Abuse Case: Roles of Behavior Problems and Frequency of Abuse.

PubMed

Theimer, Kate; Hansen, David J

2017-06-01

Youth who are blamed for their sexual abuse may experience increased negative outcomes, such as amplified self-blame. Similarly, blaming nonoffending parents can impede their ability to support their child following disclosure. Understanding the factors that influence how people perceive victim, caregiver, and perpetrator responsibility is imperative for the protection and treatment of families who have experienced sexual abuse. Little research has explored victim and abuse characteristics that influence the perception of sexual abuse. As such, the purpose of this study was to examine the roles of behavior problems and frequency of abuse in the attribution of blame in a hypothetical sexual abuse case. In addition, the relationship between several respondent characteristics and assignment of responsibility were explored as secondary aims. The study used a two (behavior problems: three suspensions in one school semester vs. no mention of behavior problems) by two (one abuse occurrence vs. five abuse occurrences) between-subjects design. Seven hundred forty-two participants read one of the four child sexual abuse (CSA) vignettes and completed measures related to responsibility. ANOVAs revealed those who read a vignette where the youth experienced multiple abuse incidents rated the victim as more responsible regardless of whether or not the youth was described as having behavior problems. Results indicate that respondents may have attributed more blame to the victim due to the belief that she could have done something to stop the abuse after the first incident. The abuse frequency manipulation when combined with the behavior manipulation appeared to relate to how respondents perceived the victim's parents. Males and younger respondents attributed more blame to the victim; however, sexual abuse or assault history did not associate with victim responsibility ratings. Clinical and research implications were discussed.

Multifocal humeral fractures.

Maresca, A; Pascarella, R; Bettuzzi, C; Amendola, L; Politano, R; Fantasia, R; Del Torto, M

2014-02-01

Multifocal humeral fractures are extremely rare. These may affect the neck and the shaft, the shaft alone, or the diaphysis and the distal humerus. There is no classification of these fractures in the literature. From 2004 to 2010, 717 patients with humeral fracture were treated surgically at our department. Thirty-five patients presented with an associated fracture of the proximal and diaphyseal humerus: synthesis was performed with plate and screws in 34 patients, and the remaining patient had an open fracture that was treated with an external fixator. Mean follow-up was 3 years and 3 months. A classification is proposed in which type A fractures are those affecting the proximal and the humeral shaft, type B the diaphysis alone, and type C the diaphysis in association with the distal humerus. Type A fractures are then divided into three subgroups: A-I, undisplaced fracture of the proximal humerus and displaced shaft fracture; A-II: displaced fracture of the proximal and humeral shaft; and A-III: multifragmentary fracture affecting the proximal humerus and extending to the diaphysis. Multifocal humeral fractures are very rare and little described in the literature, both for classification and treatment. The AO classification describes bifocal fracture of the humeral diaphysis, type B and C. The classification suggested in this article mainly concerns fractures involving the proximal and humeral shaft. A simple classification of multifocal fractures is suggested to help the surgeon choose the most suitable type of synthesis for surgical treatment. Copyright © 2013 Elsevier Ltd.

Children who have experienced physical abuse benefit from a multitude of community interventions including support programs to address emotional and behavioral stability. This pilot study evaluated the services of Bikers Against Child Abuse (BACA), a community of bikers lending intervention to abused children, using a pre/post exploratory design. Participants (N=154) were children who had been referred by parents/guardians for current or past physical and/or sexual abuse. Parents/guardians of children were interviewed four times over a course of one year. Results indicated children demonstrated substantial improvements in their overall levels of emotional distress, conduct concerns, hyperactivity, and behavioral and emotional functioning. Overall, results support the premise that services provided by BACA may serve as a unique intervention for children who have experienced abuse. Copyright © 2017 Elsevier Ltd. All rights reserved.

Abusive supervision and subordinate performance: Instrumentality considerations in the emergence and consequences of abusive supervision.

2015-07-01

Drawing from moral exclusion theory, this article examines outcome dependence and interpersonal liking as key boundary conditions for the linkage between perceived subordinate performance and abusive supervision. Moreover, it investigates the role of abusive supervision for subordinates' subsequent, objective work performance. Across 2 independent studies, an experimental scenario study (N = 157; Study 1) and a time-lagged field study (N = 169; Study 2), the negative relationship between perceived subordinate performance and abusive supervision was found to hinge on a supervisor's outcome dependence on subordinates but not on a supervisor's liking of subordinates. Furthermore, Study 2 demonstrated (a) a negative association between abusive supervision and subordinates' subsequent objective performance and (b) a conditional indirect effect of perceived performance on subsequent objective performance, through abusive supervision, contingent on the degree of outcome dependence, although these relationships did not reach conventional significance levels when controlling for prior objective performance. All in all, the findings highlight the role of instrumentality considerations in relation to abusive supervision and promote new knowledge on both origins and consequences of such supervisory behavior.

Opioid use and abuse in the United States continues to expand at an alarming rate. In this study, we examine the county-level determinants of the availability and abuse of prescription opioids to better understand the socio-ecological context, and in particular the role of the healthcare delivery system, on the prescription drug abuse epidemic. We use community-level information, data from Indiana's prescription drug monitoring program in 2011, and geospatial regression methods to identify county-level correlates of the availability and abuse of prescription opioids among Indiana's 92 counties. The findings suggest that access to healthcare generally, and to dentists and pharmacists in particular, increases the availability of prescription opioids in communities, which, in turn, is associated with higher rates of opioid abuse. The results suggest that the structure of the local healthcare system is a major determinant of community-level access to opioids adding to a growing body of evidence that the problem of prescription opioid abuse is, at least in part, an "iatrogenic epidemic."

Autoimmune pancreatitis is a chronic inflammatory disorder that is often misdiagnosed as pancreatic cancer. Since autoimmune pancreatitis is benign and responds to steroid management, it is important to diagnose it to avoid unnecessary surgical intervention. We describe a novel case of IgG4-associated autoimmune pancreatitis presenting with tubulointerstitial nephritis as renal lesions mimicking metastatic tumours but with no change in renal function.

Abuse-resistant drug delivery.

DuPont, Robert L; Bensinger, Peter B

In attempting to reduce the nonmedical use of controlled substances, a reasonable step is to educate the physicians prescribing controlled substances, including the prescription stimulants used to treat ADHD, as well as patients and family members, about the risks of nonmedical use and the dangers of giving or selling these medicines to persons for whom they were not prescribed. Patients who find benefits in the use of such medicines have a significant interest in protecting their continued access to them. Such access is potentially threatened by concerns about widespread nonmedical use. Physicians can help protect the appropriate medical use of prescription stimulants by considering the abuse potential of various medicines used to treat patients with ADHD, especially when these patients also have a history of nonmedical substance use. In addition, we suggest that today there is an opportunity to add a new and perhaps more hopeful paradigm: the wider use of drug delivery systems that make products less attractive to drug abusers. This new drug abuse prevention paradigm holds great promise for efforts to reduce the nonmedical use of prescription controlled substances, including the prescription stimulants used to treat ADHD. To achieve the full potential of this new paradigm to reduce prescription drug abuse, it will be necessary to develop standards to assess the relative abuse resistance of various drug formulations and delivery systems, as well as meaningful incentives to foster the development of these abuse-resistant delivery systems for controlled substances.

Cervical spine anomalies in Menkes disease: a radiologic finding potentially confused with child abuse.

Menkes disease is an X-linked recessive disorder of copper transport caused by mutations in ATP7A, a copper-transporting ATPase. Certain radiologic findings reported in this condition overlap with those caused by child abuse. However, cervical spine defects simulating cervical spine fracture, a known result of nonaccidental pediatric trauma, have not been reported previously in this illness. To assess the frequency of cervical spine anomalies in Menkes disease after discovery of an apparent C2 posterior arch defect in a child participating in a clinical trial. We examined cervical spine radiographs obtained in 35 children with Menkes disease enrolled in a clinical trial at the National Institutes of Health Clinical Center. Four of the 35 children with Menkes disease had apparent C2 posterior arch defects consistent with spondylolysis or incomplete/delayed ossification. Defects in C2 were found in 11% of infants and young children with Menkes disease. Discovery of cervical spine defects expands the spectrum of radiologic findings associated with this condition. As with other skeletal abnormalities, this feature simulates nonaccidental trauma. In the context of Menkes disease, suspicions of child abuse should be considered cautiously and tempered by these findings to avoid unwarranted accusations.

Abuse-Deterrent Formulations and the Prescription Opioid Abuse Epidemic in the United States: Lessons Learned From OxyContin.

PubMed

Cicero, Theodore J; Ellis, Matthew S

2015-05-01

In an effort to reduce wide-scale abuse of the proprietary oxycodone hydrochloride formulation OxyContin, an abuse-deterrent formulation (ADF) was introduced in 2010. Although the reformulation produced an immediate drop in abuse rates, a definite ceiling effect appeared over time, beyond which no further decrease was seen. To examine the factors that led to the initial steep decline in OxyContin abuse and the substantial levels of residual abuse that have remained relatively stable since 2012. We used data from the ongoing Survey of Key Informants' Patients program, part of the Researched Abuse, Diversion and Addiction-Related Surveillance system that collects and analyzes postmarketing data on misuse and diversion of prescription opioid analgesics and heroin. For our survey study, patients with a DSM-V diagnosis of opioid use disorder and primary drug of abuse consisting of a prescription opioid or heroin (N = 10,784) at entry to 1 of 150 drug treatment programs in 48 states completed an anonymous structured survey of opioid abuse patterns (surveys completed from January 1, 2009, through June 30, 2014). A subset of these patients (n = 244) was interviewed to add context and expand on the structured survey. In addition to key demographic measures, past-month abuse of opioids was the primary measure in the structured surveys. In the interviews, the effect of the introduction of the ADF on drug-seeking behavior was examined. Reformulated OxyContin was associated with a significant reduction of past-month abuse after its introduction (45.1% [95% CI, 41.2%-49.1%] in January to June 2009 to 26.0% [95% CI, 23.6%-28.4%] in July to December 2012; P < .001; χ(2) = 230.83), apparently owing to a migration to other opioids, particularly heroin. However, this reduction leveled off, such that 25% to 30% of the sample persisted in endorsing past-month abuse from 2012 to 2014 (at study end [January to June 2014], 26.7% [95% CI, 23.7%-29.6%]).

Programmable Control in Extracellular Matrix-mimicking Polymer Hydrogels.

The extracellular matrix (ECM) and cells have a reciprocal relationship, one shapes the other and vice versa. One of the main challenges of synthetic material systems for developmental cell culturing, organoid and stem cell work includes the implementation of this reciprocal nature. The largest hurdle to achieve true cell-instructive materials in biomaterials engineering is a lack of spatial and temporal control over material properties and the display of bioactive signals compared to the natural cell environment. ECM-mimicking hydrogels have been developed using a wide range of polymers, assembly and cross-linking strategies. While our synthetic toolbox is larger than nature, often our systems underperform when compared to ECM systems with natural components like Matrigel. Material properties and three-dimensional structure ill-represent the three-dimensional ECM reciprocal nature and ligand presentation is an oversimplified version of the complexity found in nature. We hypothesize that the lack of programmable control in properties and ligand presentation forms the basis of this mismatch in performance and analyze the presence of control in current state of the art ECM-mimicking systems based on covalent, supramolecular and recombinant polymers. We conclude that through combining the dynamics of supramolecular materials, robustness from covalent systems and the programmable spatial control of bio-activation in recombinant ECM materials, the optimal synthetic artificial ECM could be assembled.

To examine the associations between child physical abuse executed by a parent or caretaker and self-rated health problems/risk-taking behaviors among teenagers. Further to evaluate concurrence of other types of abuse and how these alone and in addition to child physical abuse were associated with bad health status and risk-taking behaviors. A population-based survey was carried out in 2008 among all the pupils in 2 different grades (15 respectively 17 years old) in Södermanland County, Sweden (n=7,262). The response rate was 81.8%. The pupils were asked among other things about their exposure to child physical abuse, exposure to parental intimate violence, bullying, and exposure to being forced to engage in sexual acts. Adjusted analyses were conducted to estimate associations between exposure and ill-health/risk-taking behaviors. Child physical abuse was associated with poor health and risk-taking behaviors with adjusted odds ratios (OR) ranging from 1.6 to 6.2. The associations were stronger when the pupils reported repeated abuse with OR ranging from 2.0 to 13.2. Also experiencing parental intimate partner violence, bullying and being forced to engage in sexual acts was associated with poor health and risk-taking behaviors with the same graded relationship to repeated abuse. Finally there was a cumulative effect of multiple abuse in the form of being exposed to child physical abuse plus other types of abuse and the associations increased with the number of concurrent abuse. This study provides strong indications that child abuse is a serious public health problem based on the clear links seen between abuse and poor health and behavioral problems. Consistent with other studies showing a graded relationship between experiences of abuse and poor health/risk-taking behaviors our study shows poorer outcomes for repeated and multiple abuse. Thus, our study calls for improvement of methods of comprehensive assessments, interventions and treatment in all settings where

Child abuse and mental disorders in Canada

Background: Nationally representative Canadian data on the prevalence of child abuse and its relation with mental disorders are lacking. We used contemporary, nationally representative data to examine the prevalence of 3 types of child abuse (physical abuse, sexual abuse and exposure to intimate partner violence) and their association with 14 mental conditions, including suicidal ideation and suicide attempts. Methods: We obtained data from the 2012 Canadian Community Health Survey: Mental Health, collected from the 10 provinces. Respondents aged 18 years and older were asked about child abuse and were selected for the study sample (n = 23 395). The survey had a multistage stratified cluster design (household response rate 79.8%). Results: The prevalence of any child abuse was 32% (individual types ranged from 8% to 26%). All types of child abuse were associated with all mental conditions, including suicidal ideation and suicide attempts, after adjustment for sociodemographic variables (adjusted odds ratios ranged from 1.4 to 7.9). We found a dose–response relation, with increasing number of abuse types experienced corresponding with greater odds of mental conditions. Associations between child abuse and attention deficit disorder, suicidal ideation and suicide attempts showed stronger effects for women than men. Interpretation: We found robust associations between child abuse and mental conditions. Health care providers, especially those assessing patients with mental health problems, need to be aware of the relation between specific types of child abuse and certain mental conditions. Success in preventing child abuse could lead to reductions in the prevalence of mental disorders, suicidal ideation and suicide attempts. PMID:24756625

Medical student abuse: perceptions and experience.

1993-07-01

A questionnaire containing 18 vignettes of common clinical educational situations with potentially abusive treatment of medical students and a 10-item attitude assessment about abusive behaviour were administered to the first- and fourth-year medical students at a mid-west US university medical school. The first- and fourth-year groups did not differ significantly on perceived abusiveness of most of the vignettes, although several of the individual vignettes were perceived significantly differently by the two groups. As hypothesized, the fourth-year students had experienced such situations more frequently. Attitudes towards abusive behaviour did not differ between the two groups. The authors contrast teaching interactions perceived as educationally useful and not abusive with those seen as abusive and not useful and offer explanations for the differences observed. Finally, the possible implications of the results for medical education are discussed.

[Abuse, dependence and intoxication of substances].

PubMed

Wada, Kiyoshi

As for substance-related disorders, there were several differences between ICD-10 and DSM-IV, however, the concept of "dependence" had been essential for both criteria. DSM-5 published in 2013 had erased dependence. This confuses us. It is important to recognize dependence again. "Abuse" is the self-intake behavior of drug against the social norms. Repeated abuse results in dependence. Dependence is a state of loss of control against drug use due to craving. Abuse can produce "acute intoxication", and repeated abuse under dependence can produce "chronic intoxication". It is important to understand abuse, dependence and "intoxication" based on their relationship from the point of time course.

Laboratory hydraulic fracturing experiments in intact and pre-fractured rock

Zoback, M.D.; Rummel, F.; Jung, R.; Raleigh, C.B.

1977-01-01

Laboratory hydraulic fracturing experiments were conducted to investigate two factors which could influence the use of the hydrofrac technique for in-situ stress determinations; the possible dependence of the breakdown pressure upon the rate of borehole pressurization, and the influence of pre-existing cracks on the orientation of generated fractures. The experiments have shown that while the rate of borehole pressurization has a marked effect on breakdown pressures, the pressure at which hydraulic fractures initiate (and thus tensile strength) is independent of the rate of borehole pressurization when the effect of fluid penetration is negligible. Thus, the experiments indicate that use of breakdown pressures rather than fracture initiation pressures may lead to an erroneous estimate of tectonic stresses. A conceptual model is proposed to explain anomalously high breakdown pressures observed when fracturing with high viscosity fluids. In this model, initial fracture propagation is presumed to be stable due to large differences between the borehole pressure and that within the fracture. In samples which contained pre-existing fractures which were 'leaky' to water, we found it possible to generate hydraulic fractures oriented parallel to the direction of maximum compression if high viscosity drilling mud was used as the fracturing fluid. ?? 1977.

Several problems are encountered in the study of child abuse: ignorance of its real proportions, deep cultural and historical roots, diversity of opinion as to its definition and classification and, finally, very diverse considerations on its repercussions and therapeutic management. The present study approaches child abuse from its historical precedents, its classifications, definitions and epidemiology. In addition, repercussions are reviewed, and treatment alternatives considered which are held as fundamental to confront this alarmingly increasing phenomenon. It is important to unify criteria as to the definition and classification of scientific information surrounding demographic data which, in the end, will situate the problem, the progress related to its causes, diagnosis, preventive measures and treatment. It is extremely important to prevent child abuse by all possible means, since this harm is reflected in the adult life of the child. Various classifications are considered, as well as characteristics of the abuser and of the abused.

OOC is characterised by a less-aggressive behaviour and a low rate of recurrence. This report describes a case of OOC involving posterior part of the mandible that mimicked periapical cyst in a 14-year-old boy. The initial clinical diagnosis was given as periapical cyst based on the clinical and radiographical features. Enucleation of the cyst was performed and the specimen was sent for histopathological examination. A definite diagnosis of OOC was made by histopathological examination of the biopsy specimen. This case emphases on including OOC in the differential diagnosis of radiolucencies occurring in the periapical region of non-vital tooth. PMID:24099763

Economic abuse is part of the pattern of behaviors used by batterers to maintain power and control over their partners. However, no measure of economic abuse exists. This study describes the development of the Scale of Economic Abuse, which was designed to fill this gap. Interviews were conducted with 103 survivors of domestic abuse, each of whom responded to measures of economic, physical, and psychological abuse as well as economic hardship. Results provide evidence for the reliability and validity of the scale. This study is an important first step toward understanding the extent and impact of economic abuse experienced by survivors.

Substance abuse disorders in nurses.

Substance abuse is a serious concern in the profession of nursing. The American Nurses Association (1997) estimates that 10% to 20% of nurses have substance abuse problems, and that 6% to 8% of registered nurses are impaired due to their abuse of alcohol and other drugs. Chemical dependency is considered a disease that requires treatment. Early identification and treatment of the chemically dependent nurse is important for the safety of the public and for the well-being of the nurse and her profession. This article addresses substance abuse from a biopsychosocial perspective, and includes a description of an approach to treatment and suggestions for the role of nursing administration.

Hydro-fracture in the laboratory: matching diagnostic seismic signals to fracture networks

Hydraulic fracturing is a key process in both natural (e.g. dyke intrusion) and engineered environments (e.g. shale gas). To better understand this process, we present new data from simulated hydraulic fracturing in a controlled laboratory environment in order to track fracture nucleation (location) and propagation (velocity) in space and time to assess the fracture mechanics and developing fracture network. Fluid overpressure is used to generate a permeable network of micro tensile fractures in an anisotropic sandstone and a highly anisotropic shale. A newly developed technique, using a steel guide arrangement to direct pressurised fluid into a sealed section of an axially drilled conduit, allows the pore fluid to contact the rock directly and to initiate tensile fractures from a pre-defined zone inside the sample. Acoustic emission location is used to record and map the nucleation and development of the micro-fracture network. For both rock types, fractures progresses parallel to the bedding plane (short-transverse) if the bedding plane is aligned with the direction of σ1 requiring breakdown pressures of approximately 7 and 13MPa respectively at a confining pressure of 8MPa. The data also indicates a more ductile behaviour of the shale than expected. We use X-Ray Computed Tomography (CT) to evaluate the evolved fracture network in terms of fracture pattern and aperture. Hydraulic fracturing produces very planar fractures in the shale, with axial fractures over the entire length of the sample broadly following the bedding. In contrast, fractures in the sandstone are more diffuse, linking pore spaces as they propagate. However, secondary micro cracking, branching of the main fracture, are also observed. These new experiments suggest that fracture pattern, fracture propagation trajectories, and fracturing fluid pressures are predominantly controlled by the interaction between the anisotropic mechanical properties of the rock and the anisotropic stress environment.

Naturally occurring antimicrobial peptides (AMPs) display the ability to eliminate a wide variety of bacteria, without toxicity to the host eukaryotic cells. Synthetic polymers containing moieties mimicking lysine and arginine components found in AMPs have been reported to show effectiveness against specific bacteria, with the mechanism of activity purported to depend on the nature of the amino acid mimic. In an attempt to incorporate the antimicrobial activity of both amino acids into a single water-soluble copolymer, a series of copolymers containing lysine mimicking aminopropyl methacrylamide (APMA) and arginine mimicking guanadinopropyl methacrylamide (GPMA) were prepared via aqueous RAFT polymerization. Copolymers were prepared with varying ratios of the comonomers, with degree of polymerization of 35–40 and narrow molecular weight distribution to simulate naturally occurring AMPs. Antimicrobial activity was determined against Gram-negative and Gram-positive bacteria under conditions with varying salt concentration. Toxicity to mammalian cells was assessed by hemolysis of red blood cells and MTT assays of MCF-7 cells. Antimicrobial activity was observed for APMA homopolymer and copolymers with low concentrations of GPMA against all bacteria tested, with low toxicity toward mammalian cells. PMID:26558609

The pediatric craniofacial trauma literature largely focuses on the management of mandible fractures, with very little information focusing on pediatric midface fractures, specifically nasoorbitethmoid (NOE) fractures. Because the diagnosis and surgical treatment plan for adult NOE fractures is well established in the literature, the treatment algorithms for NOE are essentially a transfer of adult practices to pediatric patients. This article reviews the differences between the pediatric and adult facial skeleton and the pathology and presentation of NOE fractures in the pediatric craniomaxillofacial skeleton. It also presents the effects of NOE fractures on the growth and development of the pediatric facial skeleton and describes the current surgical management for NOE fractures.

Characteristic Fracture Spacing in Primary and Secondary Recovery from Naturally Fractured Reservoirs

NASA Astrophysics Data System (ADS)

Gong, J.; Rossen, W.

2015-12-01

We showed previously (Gong and Rossen, 2014a,b) that, if the fracture aperture distribution is broad enough in a naturally fractured reservoir, even one where the fracture network is well-connected, most fractures can be eliminated without significantly affecting the flow through the fracture network. During a waterflood or enhanced-oil-recovery (EOR) process, the production of oil depends on the supply of injected water or EOR agent. This suggests that the characteristic fracture spacing for the dual-porosity/dual-permeability simulation of waterflood or EOR in a naturally fractured reservoir should account not for all fractures but only the relatively small portion of the fracture network carrying almost all the injected water or EOR agent. In contrast, in primary production even a relatively small fracture represents an effective path for oil to flow to a production well. Thus in primary production the effective fracture spacing should include all the fractures. This distinction means that the "shape factor" in dual-porosity/dual-permeability reservoir simulators and the repeating unit in homogenization should depend on the process involved: specifically, it should be different for primary and secondary or tertiary recovery. We test this hypothesis in a simple representation of a fractured reservoir with a non-uniform distribution of fracture flow conductivities. We compare oil production, flow patterns in matrix, and the pattern of oil recovery around fractures with and without the "unimportant" fractures present. In primary production, all fractures which are much more permeable than matrix play a significant role in production. The shape factor or repeating-unit size should reflect the entire fracture distribution. In secondary or tertiary production, the role of fractures that carry relatively little flow depends on injection rate, the ratio of flow carried by the different fractures, and the permeability of matrix. In some cases, the appropriate shape

From research findings and practice experiences, it is concluded that abuse of older men is especially invisible and underreported, compared to abuse of older women. It is proposed that attention should be directed not to gender, but to those conditions in different countries and cultures leading to abuse of both older men and women, including (but not limited to) economic problems, few alternatives to family care of the elderly, violence, changing characteristics of the family, ageism, and sexism. Advocates for the prevention of elder abuse should work together in combating, reducing, and eliminating the problem of elder abuse of both older men and older women.

2009-10-01

A case of a retained root tip simulating apical periodontitis on radiographic examination is described. The retained root tip, originating from the left lower first molar, floated under the left lower second premolar apical region mimicking apical periodontitis. It appeared as an ill-defined periapical radiolucency containing a smaller radiodense mass on radiograph. The differential diagnosis included focal sclerosing osteomyelitis (condensing osteitis) and ossifying fibroma. Upon exicisional biopsy, a retained root associated with granulation tissue was found. After 1-year follow-up, the patient was asymptomatic and the periradicular lesion was healing. Meanwhile, the associated tooth showed a normal response to stimulation testing.

Thoracic kyphosis and rate of incident vertebral fractures: the Fracture Intervention Trial.

Biomechanical analyses support the theory that thoracic spine hyperkyphosis may increase risk of new vertebral fractures. While greater kyphosis was associated with an increased rate of incident vertebral fractures, our analysis does not show an independent association of kyphosis on incident fracture, after adjustment for prevalent vertebral fracture. Excessive kyphosis may still be a clinical marker for prevalent vertebral fracture. Biomechanical analyses suggest hyperkyphosis may increase risk of incident vertebral fracture by increasing the load on vertebral bodies during daily activities. We propose to assess the association of kyphosis with incident radiographic vertebral fracture. We used data from the Fracture Intervention Trial among 3038 women 55-81 years of age with low bone mineral density (BMD). Baseline kyphosis angle was measured using a Debrunner kyphometer. Vertebral fractures were assessed at baseline and follow-up from lateral radiographs of the thoracic and lumbar spine. We used Poisson models to estimate the independent association of kyphosis with incident fracture, controlling for age and femoral neck BMD. Mean baseline kyphosis was 48° (SD = 12) (range 7-83). At baseline, 962 (32%) participants had a prevalent fracture. There were 221 incident fractures over a median of 4 years. At baseline, prevalent fracture was associated with 3.7° greater average kyphosis (95% CI 2.8-4.6, p < 0.0005), adjusting for age and femoral neck BMD. Before adjusting for prevalent fracture, each 10° greater kyphosis was associated with 22% increase (95% CI 8-38%, p = 0.001) in annualized rate of new radiographic vertebral fracture, adjusting for age and femoral neck BMD. After additional adjustment for prevalent fracture, estimated increased annualized rate was attenuated and no longer significant, 8% per 10° kyphosis (95% CI -4 to 22%, p = 0.18).

In many parts of the world, elder abuse happens almost unnoticed. Until recently, this serious social problem was hidden from public view and was regarded as an essentially private matter. However, there is growing evidence that elder abuse is an important problem of public health and in the society. The objective of this study is to determine the degree of abuse of elder and vulnerable people in the families and communities of Eastern Bolivia. With this end in mind, we conducted a cross-sectional descriptive study with a sample size of 210 60-year-old people coming from different health care areas. Elder Abuse Suspicion Index (EASI) and Yaffe's Evaluation Form of Social Work were used. An abuse rate of 39% of the older adults was identified. The most common type of abuse observed was psychological abuse (32.4% of cases), followed by neglect (21.9%). Children were identified as triggers of the abuse in 66.7% of cases of abuse. The prevalence of elder abuse was similar to the prevalence of other types of abuse that exist in Bolivia, such as the gender-based abuse. Also, this prevalence is comparable to other developing countries and European countries. The profile of abused older adult is as follows: woman, widow, 70 years old, incomplete primary education, without an occupation, and an average of 4.59 children. The information obtained shows that dysfunctional families have a higher percentage of elder abuse. © The Author(s) 2015.

Child Sexual Abuse in Zimbabwe.

PubMed

Mantula, Fennie; Saloojee, Haroon

2016-01-01

Although child sexual abuse is a significant public health problem globally, its incidence, prevention, and management is less well described in resource-poor settings. In poorer settings prevention initiatives assume even more importance since resources for managing abused children are severely limited. This article examines the current status of policy and practice related to the prevention of child sexual abuse in Zimbabwe. It identifies implementation challenges and highlights opportunities that could be embraced to reduce CSA in Zimbabwe, based on evidence synthesized from recent work. Although Zimbabwe has a well-established legal and regulatory framework to protect children from child sexual abuse, implementation of existing policies is weak. Financial, human, and material resource constraints are frequently cited to explain limited prevention activity. Effective strategies for the prevention of child sexual abuse should focus on implementing existing legislation, targeting schoolchildren, and getting community involvement. A dedicated budget would help entrench these strategies, but gains can be achieved even in the absence of this.

To investigate oral health sensations (short term oral health effects) associated with illicit drug abuse. In addition, to identify variations in oral health sensations produced by different illicit drugs. Young adults in a drug rehabilitation programme in Hong Kong, China. Self-completed questionnaire about their previous pattern of drug abuse and oral health sensations experienced (recalled). All (119) subjects were poly-drug abusers (abused one or more illicit drugs in the past). Amphetamine-based drugs such as methamphetamine ('speed') and methylenedioxymethamphetine ('ecstasy') were commonly abused. A wide range of oral health sensations were reported on recall of their abuse of illicit drugs; most frequently dry mouth (95%, 113). Types of illicit drugs abused were associated with oral health sensations reported (P < 0.001). 'Ecstasy' abusers more frequently reported chewing (P < 0.001), grinding (P < 0.001), and TMJ tenderness (P < 0.001) compared to non-'ecstasy' abusers. Illicit drug abuse produces many oral health sensations. Types of drugs abused were associated with oral sensations produced. and behavioural effects that may manifest as depression, anxiety, memory loss and various neuropsychotic disorders.(8),(9) In some cases drug abuse can result in death by various means: malignant hyperthermia, internal bleeding, fatal overdosing and through allergic reactions.(10),(11) Likewise, there have been reports on the long term clinical effects of illicit drug abused on oral health.

The aim of this paper was to examine the association between reporting childhood sexual abuse (CSA) and alcohol abuse in a community sample of women using multivariate analysis which took into account a range of potential confounding variables (such as a family history of alcoholism) and effect modifiers (such as having an alcoholic partner). A two-stage retrospective case-control study was used to investigate the relationship between reporting CSA and alcohol abuse in women. Seven hundred and ten women randomly selected from the Australian federal electoral rolls. The Alcohol Use Disorders Identification Test (AUDIT) was used to measure alcohol abuse. A series of questions based on those developed by Wyatt (1985) were used to ascertain the prevalence of CSA. The final model showed that the relationship between a history of CSA and alcohol abuse reflected a complex interaction between CSA and a range of other factors in a woman's background. CSA was not by itself a significant predictor of alcohol abuse (OR = 0.61; 95% CI = 0.31-1.20). However, a history of CSA became significant in combination with co-factors which included: having a mother who was perceived as cold and uncaring; having an alcoholic partner; and believing that alcohol is a sexual disinhibitor. This study indicates that CSA alone is not a causative factor in the development of alcohol abuse among women and highlights the importance of examining the family background of women with alcohol problems.

Integration of fracturing dynamics and pressure transient analysis for hydraulic fracture evaluation

Arihara, N.; Abbaszadeh, M.; Wright, C.A.

This paper presents pre- and post-fracture pressure transient analysis, combined with net fracture pressure interpretation, for a well in a naturally fractured geothermal reservoir. Integrated analysis was performed to achieve a consistent interpretation of the created fracture geometry, propagation, conductivity, shrinkage, reservoir flow behavior, and formation permeability characteristics. The interpreted data includes two-rate pre-frac injection tests, step-rate injection tests, a series of pressure falloff tests, and the net fracturing pressure from a massive fracture treatment. Pressure transient analyses were performed utilizing advanced well test interpretation techniques and a thermal reservoir simulator with fracture propagation option. Hydraulic fracture propagation analysis wasmore » also performed Milt a generalized 3-D dynamic fracture growth model simulator. Three major conclusions resulted from the combined analysis: (1) that an increasing number of hydraulic fractures were being simultaneously propagated during the fracture treatment. (2) that the reservoir behaved as a composite reservoir Keith the outer region permeability being greater than the permeability of the region immediately surrounding the wellbore, and (3) that the created fractures extended into the outer region during the fracture treatment but retreated to the inner region several days after stimulation had ceased. These conclusions were apparent from independent pressure transient analysis and from independent hydraulic fracture propagation analysis. Integrated interpretation, however, increased the confidence in these conclusions and greatly aided the quantification of the created hydraulic fracture geometry and characterization of the reservoir permeability.« less

Prescription opioid abuse based on representative postmortem toxicology.

Opioids are important medications for pain and opioid maintenance treatment. Increasing use and abuse of prescription opioids has, however, caused worldwide concern. Our aim was to estimate the ratio between prescription opioid abuse and total use, based on representative postmortem toxicology. Our material included all the medico-legally examined deaths in Finland during 2010-2011 involving positive findings involving buprenorphine, codeine, fentanyl, methadone, oxycodone, or tramadol. We studied drug abuse by age group, with "abuse" meaning licit opioids used illicitly as narcotics. Drug-abuse history, drug injecting, or laboratory findings of illicit drugs defined an abuser case. We then compared abuser cases and other opioid-related cases between the opioids with the number of fatal poisonings, accidents, suicides, alcohol findings, concomitant opioid use, and median postmortem blood opioid concentrations. Opioid findings numbered 2499 in 2088 cases. Drug abuse involved 545 opioid-positive cases, which in Finland represented 0.5% of those deceased. The proportion of abuser cases among all opioid-related cases for buprenorphine was 85.5%, for methadone 82.4%, for tramadol 29.4%, for codeine 16.3%, for fentanyl 14.5%, and for oxycodone 6.9%. Abuse in age-groups >60 was rare. Concomitant other opioid findings were more frequent in abuser- than in other cases for codeine, oxycodone, and tramadol, whereas alcohol findings were more frequent in buprenorphine, codeine, and fentanyl abuse. Buprenorphine and methadone were most often related to drug abuse. Every other opioid studied involved some abuse, and especially tramadol. Abuse and fatal poisonings were concentrated in men aged 20-49. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Methylphenidate: increased abuse or appropriate use?

To address the question of the significant increase in methylphenidate (MPD) prescriptions being written and to make recommendations for health care providers involved in providing care for patients with attention deficit hyperactivity disorder (ADHD) and their families. Medline search 1966-1998 for professional articles using the following search terms--methylphenidate, children, adolescents, abuse; Internet search using MPD, Ritalin, and ADHD; and Paper Chase search using methylphenidate. The available literature regarding potential abuse or diversion of MPD consists of case reports, review articles, newspaper articles, and a Drug Enforcement Administration (DEA) publication. All available literature sources were used. Although the media and DEA report significant abuse and diversion of prescribed MPD, a review of the available literature did not reveal data to substantiate these claims. Nonetheless, there are reasons to suspect that abuse and diversion occur. A potential contributing factor to abuse is the reported similarities in pharmacodynamics and pharmacokinetics between MPD and cocaine. Recommendations are made to decrease the possibility of abuse and diversion of prescribed MPD. A balanced middle ground must be found regarding the benefits of MPD and its abuse potential. Education of clinicians, patients, and family members is key in ensuring that MPD is used appropriately.

Caregiver-associated cues, including those learned in abusive attachment, provide a sense of safety and security to the child. Here, we explore how cues associated with abusive attachment, such as maternal odor, can modify the enduring neurobehavioral effects of early-life abuse. Two early-life abuse models were used: a naturalistic paradigm, where rat pups were reared by an abusive mother; and a more controlled paradigm, where pups underwent peppermint odor-shock conditioning that produces an artificial maternal odor through engagement of the attachment circuit. Animals were tested for maternal odor preference in infancy, forced swim test (FST), social behavior, and sexual motivation in adulthood—in the presence or absence of maternal odors (natural or peppermint). Amygdala odor-evoked local field potentials (LFPs) via wireless electrodes were also examined in response to the maternal odors in adulthood. Both early-life abuse models induced preference for the maternal odors in infancy. In adulthood, these early-life abuse models produced FST deficits and decreased social behavior, but did not change sexual motivation. Presentation of the maternal odors rescued FST and social behavior deficits induced by early-life abuse and enhanced sexual motivation in all animals. In addition, amygdala LFPs from both abuse animal models showed unique activation within the gamma frequency (70–90 Hz) bands in response to the specific maternal odor present during early-life abuse. These results suggest that attachment-related cues learned during infancy have a profound ability to rescue neurobehavioral dysregulation caused by early-life abuse. Paradoxically, abuse-associated cues seem to acquire powerful and enduring antidepressive properties and alter amygdala modulation. PMID:25284320

Influence of Natural Fractures Cohesive Properties on Geometry of Hydraulic Fracture Networks

Gonzalez-Chavez, M. A.; Dahi Taleghani, A.; Puyang, P.

2014-12-01

An integrated modeling methodology is proposed to analyze hydraulic fracturing jobs in the presence of the natural fracture network in the formation. A propagating hydraulic fracture may arrest, cross, or diverts into a preexisting natural crack depending on fracture properties of rock and magnitude and direction of principal rock stresses. Opening of natural fractures during fracturing treatment could define the effectiveness of the stimulation technique. Here, we present an integrated methodology initiated with lab scale fracturing properties using Double Cantilever Beam tests (DCB) to determine cohesive properties of rock and natural fractures. We used cohesive finite element models to reproduce laboratory results to verify the numerical model for the interaction of the hydraulic fracture and individual cemented natural fractures. Based on the initial investigations, we found out that distribution of pre-existing natural fractures could play a significant role in the final geometry of the induced fracture network; however in practice, there is not much information about the distribution of natural fractures in the subsurface due to the limited access. Hence, we propose a special optimization scheme to generate natural fracture geometry from the location of microseismic events. Accordingly, the criteria of evaluating the fitness of natural fracture realizations is defined as the total minimum distance squares of all microseismic events, which is the sum of minimum square distance for all microseismic events. Moreover, an additional constraint in this problem is that we need to set a minimum distance between fracture grids. Using generated natural fracture realizations, forward field-scale simulations are implemented using cohesive finite element analysis to find the best match with the recorded bottomhole pressure. To show the robustness of the proposed workflow for real field problem, we implemented this technique on available data from several well Chicontepec

Evaluating the abuse potential of opioids and abuse-deterrent -opioid formulations: A review of clinical study methodology.

PubMed

Setnik, Beatrice; Schoedel, Kerri A; Levy-Cooperman, Naama; Shram, Megan; Pixton, Glenn C; Roland, Carl L

With the development of opioid abuse-deterrent formulations (ADFs), there is a need to conduct well-designed human abuse potential studies to evaluate the effectiveness of their deterrent properties. Although these types of studies have been conducted for many years, largely to evaluate inherent abuse potential of a molecule and inform drug scheduling, methodological approaches have varied across studies. The focus of this review is to describe current "best practices" and methodological adaptations required to assess abuse-deterrent opioid formulations for regulatory submissions. A literature search was conducted in PubMed® to review methodological approaches (study conduct and analysis) used in opioid human abuse potential studies. Search terms included a combination of "opioid," "opiate," "abuse potential," "abuse liability," "liking," AND "pharmacodynamic," and only studies that evaluated single doses of opioids in healthy, nondependent individuals with or without prior opioid experience were included. Seventy-one human abuse potential studies meeting the prespecified criteria were identified, of which 21 studies evaluated a purported opioid ADF. Based on these studies, key methodological considerations were reviewed and summarized according to participant demographics, study prequalification, comparator and dose selection, route of administration and drug manipulation, study blinding, outcome measures and training, safety, and statistical analyses. The authors recommend careful consideration of key elements (eg, a standardized definition of a "nondependent recreational user"), as applicable, and offer key principles and "best practices" when conducting human abuse potential studies for opioid ADFs. Careful selection of appropriate study conditions is dependent on the type of ADF technology being evaluated.

Suicide attempts among men with histories of child sexual abuse: examining abuse severity, mental health, and masculine norms.

Men who were sexually abused during childhood are at risk for a variety of long-term mental health problems, including suicidality. However, little is known about which factors are related to recent suicide attempts for this vulnerable, under-researched population. The purpose of this study was to examine the relationship between abuse severity, mental health, masculine norms and recent suicide attempts among men with histories of child sexual abuse (CSA). We analyzed survey data gathered from a purposive sample of 487 men who were sexually abused during childhood. The age of the sample ranged from 19 to 84 years (μ = 50.4 years). Recent suicide attempts served as the dependent variable in the study. Self-reported measures of sexual abuse severity, child physical abuse, mental health, masculine norms, and demographic information (age, race) represented the independent variables. The results from logistic regression modeling found that five variables - duration of the sexual abuse, use of force during the sexual abuse, high conformity to masculine norms, level of depressive symptoms, and suicidal ideation - increased the odds of a suicide attempt in the past 12 months. To improve mental health services for men with histories of CSA, mental health practitioners should incorporate sexual abuse severity, current mental health, and adherence to masculine norms into assessment and treatment planning.

To describe nationally representative outcomes of physical abuse injuries in children necessitating Emergency Department (ED) visits in United States. The impact of various injuries on mortality is examined. We hypothesize that physical abuse resulting in intracranial injuries are associated with worse outcome. We performed a retrospective analysis of the Nationwide Emergency Department Sample (NEDS), the largest all payer hospital based ED database, for the years 2008-2010. All ED visits and subsequent hospitalizations with a diagnosis of "Child physical abuse" (Battered baby or child syndrome) due to various injuries were identified using ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification) codes. In addition, we also examined the prevalence of sexual abuse in this cohort. A multivariable logistic regression model was used to examine the association between mortality and types of injuries after adjusting for a multitude of patient and hospital level factors. Of the 16897 ED visits that were attributed to child physical abuse, 5182 (30.7%) required hospitalization. Hospitalized children were younger than those released treated and released from the ED (1.9 years vs. 6.4 years). Male or female partner of the child's parent/guardian accounted for >45% of perpetrators. Common injuries in hospitalized children include- any fractures (63.5%), intracranial injuries (32.3%) and crushing/internal injuries (9.1%). Death occurred in 246 patients (13 in ED and 233 following hospitalization). Amongst the 16897 ED visits, 1.3% also had sexual abuse. Multivariable analyses revealed each 1 year increase in age was associated with a lower odds of mortality (OR = 0.88, 95% CI = 0.81-0.96, p < 0.0001). Females (OR = 2.39, 1.07-5.34, p = 0.03), those with intracranial injuries (OR = 65.24, 27.57-154.41, p<0.0001), or crushing/internal injury (OR = 4.98, 2.24-11.07, p<0.0001) had higher odds of mortality compared to their male counterparts.

The purpose of this descriptive study was to: (a) compare the demographics of maltreated youth initially labeled as sexually abused by the Department of Child and Family Services (DCFS) to maltreated youth classified as sexually abused using current and past case records, (b) identify differences in sexual abuse experiences and types of perpetrators between boys and girls, and (c) provide a detailed description of the sexual abuse experiences for boys and girls. Participants were youth ages 9–12 years old with a recent maltreatment allegation. The Maltreatment Case Record Abstraction Instrument (MCRAI) was used to code child welfare records of 303 maltreated youth of whom 60 experienced sexual abuse. Perpetrators were classified by gender into four categories (biological parent, parental figure, relative, and unrelated) and type of abuse was classified into three categories (penetrative, contact without penetration, and non-contact). Using Chi-Square tests, perpetrator categories and sexual abuse types were compared by child gender for significant differences. Only 23 (38.3%) of the 60 sexually abused youth were labeled as sexually abused in the most recent DCFS report when they entered the study. About three-quarters of the sexually abused youth experienced non-penetrative physical contact, 40% experienced penetration, and 15% experienced sexual abuse without physical contact. Most youth (91.7%) were victimized by a male, and 21.7% were abused by a female. Youth experienced a large range of sexual abuse experiences, the details of which may be important for exploration of consequences of childhood sexual abuse. PMID:24095179

This study investigated the personality inferences people draw about abusive mothers by having 287 subjects view videotapes of four female targets engaged in social discourse with other adults. Some subjects were primed beforehand to believe that the female targets had physically abused or neglected their child and other subjects viewed the tapes without being primed. Afterward, all subjects rated the targets' personalities using 17 bipolar trait scales and estimating the likelihood of six social behaviors. Analyses compared the ratings of the two types of abuse groups (physical abuse and neglect) with each other and with the unprimed control group. Analysis showed that ratings of one or both of the abuse groups differed from those of the control group on 10 of the 17 trait dimensions and four of six social behaviors. Implications are drawn about the social forces experienced by abusive mothers and the possible role of such forces in therapeutic change.

Teen dating abuse: recognition and interventions.

2013-03-01

Teen dating abuse, also known as teen dating violence, is a significant public health issue. Adolescents with a history of dating abuse may struggle academically and experience increased risk for serious injury or even death. They may engage in risky sexual behavior, substance abuse, and unhealthy dieting and exhibit suicidal behaviors. School nurses may be the first adults that teens confide in when experiencing dating abuse and may lack the knowledge and skills to intervene with teens involved in unhealthy dating relationships. Beginning in 2008, Dell Children s Medical Center in Austin, Texas, partnered with SafePlace (a local nonprofit that serves survivors of sexual and domestic violence) to address dating abuse. This collaboration is part of Start Strong Austin, one of 11 communities nationwide participating in the Start Strong: Building Healthy Teen Relationships Initiative funded by the Robert Wood Johnson Foundation. The Start Strong model employs innovative strategies in education, community engagement, policy change, and social marketing to prevent dating abuse before it starts.

Mortality Following Periprosthetic Proximal Femoral Fractures Versus Native Hip Fractures.

2018-04-04

The number of periprosthetic proximal femoral fractures is expected to increase with the increasing prevalence of hip arthroplasties. While native hip fractures have a well-known association with mortality, there are currently limited data on this outcome among the subset of patients with periprosthetic proximal femoral fractures. Using the New York Statewide Planning and Research Cooperative System, we identified patients from 60 to 99 years old who were admitted to a hospital in the state with a periprosthetic proximal femoral fracture (n = 1,655) or a native hip (femoral neck or intertrochanteric) fracture (n = 97,231) between 2006 and 2014. Within the periprosthetic fracture cohort, the indication for the existing implant was not available in the data set. We used mixed-effects regression models to compare mortality at 1 and 6 months and 1 year for periprosthetic compared with native hip fractures. The risk of mortality for patients who sustained a periprosthetic proximal femoral fracture was no different from that for patients who sustained a native hip fracture at 1 month after injury (3.2% versus 4.6%; odds ratio [OR], 0.90; 95% confidence interval [CI], 0.68 to 1.19; p = 0.446), but was lower at 6 months (3.8% versus 6.5%; OR, 0.74; 95% CI, 0.57 to 0.95; p = 0.020) and 1 year (9.7% versus 15.9%; OR, 0.71; 95% CI, 0.60 to 0.85; p < 0.001). Among periprosthetic proximal femoral fractures, factors associated with a significantly increased risk of mortality at 1 year included advanced age, male sex, and higher Deyo comorbidity scores. In the acute phase, any type of hip fracture appears to confer a similar risk of death. Over the long term, however, periprosthetic proximal femoral fractures are associated with lower mortality rates than native hip fractures, even after accounting for age and comorbidities.

Many hypotheses have been formulated to explain why anaesthesiologists appear to be more susceptible to substance abuse than other medical professionals (genetic differences in sensitivity to opioids, stress, the association between chemical dependence and other psychopathology or the second-hand exposure hypothesis). Environmental exposure and sensitization may be an important risk factor in physician addiction. There is a long debate about returning to work for an anaesthetist who has been depending on opioid drugs, and recent debates are discussed. Institutional efforts have been made in many countries and physician health programmes have been developed. As drug abuse among anaesthesiologists has continued, new studies have been conducted to know the theories about susceptibility. Written substance abuse policies and controls must be taken in place and in all countries.

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.

To evaluate the efficacy of a specific counseling and withdrawal program for drug-abusing pregnant women and its effect on perinatal outcome. An analysis of 120 pregnancies followed in 111 drug-abusing women giving birth at the Department of Obstetrics and Gynecology, Helsinki University Central Hospital, in 1985-95. Personnel responsible for local maternity care in the Helsinki area were trained to identify pregnant drug-abusers and to refer them to our hospital for clinical antenatal care and counseling with psychological and social support. Substance abuse during pregnancy was monitored by self-report and serial urine screenings. Obstetric and perinatal outcome were compared between those who succeeded in quitting totally or reducing drug use, and those who continued their drug use throughout pregnancy. The significance of the differences was tested by Student's unpaired t-test and binomial t-test. Of the women, 62% registered before the 20th week of pregnancy and 32% during the 20th-29th week of pregnancy (mean 18.4+/-6.6 weeks). Twelve women were admitted to an obstetric ward for withdrawal. In 73 of the 120 (61%) pregnancies the woman succeeded either in quitting totally or reducing drug abuse. Among this group, incidence of preterm birth (4.1%) was smaller (p<0.001), and gestational age (39.8+/-2.2 weeks) and birth weight (3393+/-605 gr) higher (p<0.05) than those (19.6%, 38.3+/-3.4 wk and 3049+/-728 gr, respectively) in the group continuing their drug abuse. Additionally, the percentage of normal delivery (80.8%) was higher (p<0.05), and incidence of withdrawal symptoms (19.2%), lower (p<0.001) than for those who continued drug abuse (65.2% and 47.8%, respectively). Carefully monitored counseling program for pregnant drug abusers is effective in reducing the amount of drugs used and improves perinatal outcome.

Viscoelastic Fracturing As a Migration and Expulsion Mechanism for Hydrocarbons in Shales: Analog Experiments

NASA Astrophysics Data System (ADS)

Van Damme, H.

2014-12-01

We report the results of simple laboratory experiments aimed at mimicking the generation, migration, and expulsion process of oil or gas from soft clayey sediments, triggered by thermal decomposition of organic matter. In previously published work, we showed that the injection of fluids into a soft sediment layer confined within a quasi-2D Hele-Shaw cell led to the transition from a viscous fingering invasion regime to a viscoelastic fracturing regime. The transition is controlled by the ratio of the characteristic times for the invasion process and for the structural relaxation in the sediment, respectively (Deborah number). Here we show that expulsion is a discontinuous quasi-periodic process, driven by the elastic energy stored in the embedding layers. We report also about two sets of experiments aimed at understanding the conditions in which fluid generation from multiple sources can generate a highly connected network of fractures for expulsion. In a first set of experiments, a Hele-Shaw cell with multiple injection points and multiple outlets was used. It is shown that, due to attractive elastic interactions between cracks, a network spontaneously forms as soon as invasion proceeds in the viscoelastic regime. On the contrary, no network of migration paths is forming in the viscous fingering regime, due to the effective repulsion of the fluid channels. In the second set of analog experiments, we used a thermostated mini-Hele-Shaw cell, the gap of which was filled with a strong clay mud in which microcrystals of reactive organic matter (azoisobutyronitrile, AIBN) are dispersed, or with a mud prepared with clay particles on which the organic matter was pre-impregnated. AIBN decomposes around 70°C, releasing nitrogen gas. It was again observed that, depending on the viscoelastic properties of the clay matrix, gas evolution occurs either by formation and coalescence of bubbles, or by formation of a percolating network of fractures.

ABSTRACT OBJECTIVE To examine harassment and abusive encounters between family physicians and their patients or colleagues in the workplace. DESIGN Qualitative case study using semistructured interviews. SETTING Province of New Brunswick. PARTICIPANTS Forty-eight family physicians from across the province. METHODS A collective case-study approach was developed, with 24 cases of 2 individuals per case. Cases were selected based on sex, location (urban or rural), language (French or English), and number of years since medical school graduation (< 10 years, 10 to 20 years, or > 20 years). Physicians were interviewed in either French or English. Participants were recruited using the College of Physicians and Surgeons of New Brunswick’s physician directory. Based on the rates of response and participation, some cases were overrepresented, while others were not completed. All interviews were audiotaped, transcribed verbatim, and analyzed thematically using a categorical aggregation approach. A coding scheme for the thematic analysis was developed by the research team before the interviews were transcribed. MAIN FINDINGS Although the original intent of this study was to examine the work environment of family physicians in light of the increasing number of women entering the profession, harassment and abusive encounters in the workplace emerged as a main theme. These encounters ranged from minor to severe. Minor abusive encounters included disrespectful behaviour and verbal threats by patients, their families, and occasionally colleagues. More severe forms of harassment involved physical threats, physical encounters, and stalking. Demanding patients, such as heavy drug users, were often seen as threatening. Location of practice, years in practice, and sex of the physician seemed to affect abusive encounters—young, female, rural physicians appeared to experience such encounters most often. CONCLUSION Abusive encounters in the workplace are concerning. It is essential to

The aim of this research study is to identify risk factors typical of different types of suspected child abuse reported at a hospital. The study was based on 114 cases of children for whom some type of abuse was reported. Physical abuse was the most frequently reported of all types of suspected child abuse. Most victims of sexual abuse were female and at least half the cases of neglect and physical abuse were attributed to parents. Most cases were identified in the emergency room by nurses. Children older than 10 were more susceptible to physical abuse and neglect. © 2014.

Coupled Fracture and Flow in Shale in Hydraulic Fracturing

Carey, J. W.; Mori, H.; Viswanathan, H.

2014-12-01

Production of hydrocarbon from shale requires creation and maintenance of fracture permeability in an otherwise impermeable shale matrix. In this study, we use a combination of triaxial coreflood experiments and x-ray tomography characterization to investigate the fracture-permeability behavior of Utica shale at in situ reservoir conditions (25-50 oC and 35-120 bars). Initially impermeable shale core was placed between flat anvils (compression) or between split anvils (pure shear) and loaded until failure in the triaxial device. Permeability was monitored continuously during this process. Significant deformation (>1%) was required to generate a transmissive fracture system. Permeability generally peaked at the point of a distinct failure event and then dropped by a factor of 2-6 when the system returned to hydrostatic failure. Permeability was very small in compression experiments (< 1 mD), possibly because of limited fracture connectivity through the anvils. In pure share experiments, shale with bedding planes perpendicular to shear loading developed complex fracture networks with narrow apertures and peak permeability of 30 mD. Shale with bedding planes parallel to shear loading developed simple fractures with large apertures and a peak permeability as high as 1 D. Fracture systems held at static conditions for periods of several hours showed little change in effective permeability at hydrostatic conditions as high as 140 bars. However, permeability of fractured systems was a function of hydrostatic pressure, declining in a pseudo-linear, exponential fashion as pressure increased. We also observed that permeability decreased with increasing fluid flow rate indicating that flow did not follow Darcy's Law, possibly due to non-laminar flow conditions, and conformed to Forscheimer's law. The coupled deformation and flow behavior of Utica shale, particularly the large deformation required to initiate flow, indicates the probable importance of activation of existing

Imbedded-Fracture Formulation of THMC Processes in Fractured Media

NASA Astrophysics Data System (ADS)

Yeh, G. T.; Tsai, C. H.; Sung, R.

2016-12-01

Fractured media consist of porous materials and fracture networks. There exist four approaches to mathematically formulating THMC (Thermal-Hydrology-Mechanics-Chemistry) processes models in the system: (1) Equivalent Porous Media, (2) Dual Porosity or Dual Continuum, (3) Heterogeneous Media, and (4) Discrete Fracture Network. The first approach cannot explicitly explore the interactions between porous materials and fracture networks. The second approach introduces too many extra parameters (namely, exchange coefficients) between two media. The third approach may make the problems too stiff because the order of material heterogeneity may be too much. The fourth approach ignore the interaction between porous materials and fracture networks. This talk presents an alternative approach in which fracture networks are modeled with a lower dimension than the surrounding porous materials. Theoretical derivation of mathematical formulations will be given. An example will be illustrated to show the feasibility of this approach.

Prevalence of substance abuse and socio-economic differences in substance abuse in an Australian community-dwelling elderly sample

A sample of 324 55–90-year-old Australian adults participated in a survey on elderly substance abuse using the Clinical Assessment Scales for the Elderly. Overall, males had a higher prevalence rate of substance abuse than females. Significant differences in substance abuse mean scores were found for gender, age, income, community involvement, and retirement. The findings also reveal that being a female, involved in community groups, being a retiree, and being a non-baby boomer are protective factors of substance abuse. Being an upper medium income earner appears to be a risk factor of substance abuse. PMID:28567302

External fixation of tibial pilon fractures and fracture healing.

PubMed

Ristiniemi, Jukka

2007-06-01

Distal tibial fractures are rare and difficult to treat because the bones are subcutaneous. External fixation is commonly used, but the method often results in delayed union. The aim of the present study was to find out the factors that affect fracture union in tibial pilon fractures. For this purpose, prospective data collection of tibial pilon fractures was carried out in 1998-2004, resulting in 159 fractures, of which 83 were treated with external fixation. Additionally, 23 open tibial fractures with significant > 3 cm bone defect that were treated with a staged method in 2000-2004 were retrospectively evaluated. The specific questions to be answered were: What are the risk factors for delayed union associated with two-ring hybrid external fixation? Does human recombinant BMP-7 accelerate healing? What is the role of temporary ankle-spanning external fixation? What is the healing potential of distal tibial bone loss treated with a staged method using antibiotic beads and subsequent autogenous cancellous grafting compared to other locations of the tibia? The following risk factors for delayed healing after external fixation were identified: post-reduction fracture gap of >3 mm and fixation of the associated fibula fracture. Fracture displacement could be better controlled with initial temporary external fixation than with early definitive fixation, but it had no significant effect on healing time, functional outcome or complication rate. Osteoinduction with rhBMP-7 was found to accelerate fracture healing and to shorten the sick leave. A staged method using antibiotic beads and subsequent autogenous cancellous grafting proved to be effective in the treatment of tibial bone loss. Healing potential of the bone loss in distal tibia was at least equally good as in other locations of the tibia.

IGF-I abuse in sport.

It is widely believed that growth hormone (GH) is abused by athletes for its anabolic and lipolytic effects. Many of the physiological effects of GH are mediated by the production of insulin-like growth factor-I (IGF-I). Both GH and IGF-I appear on the World Anti-Doping Agency list of prohibited substances. Little is known, however, about the prevalence of abuse with exogenous IGF-I. IGF-I has effects on carbohydrate, lipid and protein metabolism and some of these actions could prove beneficial to competitive athletes. No studies have demonstrated a positive effect of IGF-I on physical performance in healthy individuals but this has not yet been studied in appropriately designed trials. Two pharmaceutical preparations of IGF-I have recently become available for the treatment of growth disorders in children. This availability is likely to increase the prevalence of IGF-I abuse. Combining IGF-I with its binding protein IGFBP-3 in one preparation has the potential to reduce the side-effect profile but the adverse effects of long term IGF-I abuse are currently unknown. Detection of abuse with IGF-I is a major challenge for anti-doping authorities. It is extremely difficult to distinguish the exogenous recombinant form of the hormone from endogenously-produced IGF-I. One approach currently being investigated is based on measuring markers of GH and IGF-I action. This has already proved successful in the fight against GH abuse and, it is hoped, will subsequently lead to a similar test for detection of IGF-I abuse.

The prevalence of childhood sexual and physical abuse among persons with severe mental illness (SMI) is disproportionately high. Adults with SMI also engage in high rates of HIV risk behaviors. This study examined the association between childhood abuse and adult victimization, substance abuse, and lifetime HIV sexual risk in a sample of 152 adults with SMI receiving community mental health services. Structured interviews assessed psychiatric, psychosocial, and behavioral risk factors. Seventy percent reported childhood physical and/or sexual abuse, and 32% reported both types of abuse. Participants with childhood abuse were more likely to report adult victimization and greater HIV risk. A structural equation model found that childhood abuse was directly and indirectly associated with HIV risk through drug abuse and adult vicitimization. Integrated treatment approaches that address interpersonal violence and substance abuse may be necessary for HIV risk reduction in this population.

Women's reasons for leaving abusive spouses.

Ulrich, Y C

Research has focused on factors associated with leaving physically abusive relationships, yet little is known about what the woman thinks when she leaves. Fifty-one formerly battered women from rural and metropolitan areas in two midwestern states described 86 reasons for leaving a physically abusive relationship. During open-ended interviews, women who rated themselves as severely abused spontaneously emphasized leaving as a process. Content analysis resulted in reasons categorized as safety, dependency, and personal growth. Self-report retrospective data from a nonrandom sample limit generalizability of results; however, the awareness and reasoning of the women, coupled with their emphasis on leaving as process and personal growth, suggest the importance of education and support programs for abused women and women at risk for abuse.

Methylphenidate Abuse and Psychiatric Side Effects

PubMed Central

Morton, W. Alexander; Stockton, Gwendolyn G.

2000-01-01

Methylphenidate is a central nervous system stimulant drug that has become the primary drug of choice in treating attention-deficit/hyperactivity disorder in children. Side effects are usually mild and are generally well tolerated by patients. Along with increases in prescribing frequency, the potential for abuse has increased. Intranasal abuse produces effects rapidly that are similar to the effects of cocaine in both onset and type. The clinical picture of stimulant abuse produces a wide array of psychiatric symptoms. There is little in the literature to differentiate methylphenidate from other stimulants when they are abused. The need for education of all involved with the use of methylphenidate is discussed to help prevent an increasing pattern of methylphenidate abuse. PMID:15014637

This 1-year cohort study of nursing home residents revealed that historical fractures of upper limbs or nonhip lower limbs were associated with hip fracture (hazard ratio = 2.14), independent of activities of daily living (ADL), mobility, dementia, weight, and type of nursing home. Prior nonhip fractures are useful for predicting of hip fracture in institutional settings. The aim of this study was to evaluate the utility of fracture history for the prediction of hip fracture in nursing home residents. This was a cohort study with a 1-year follow-up. Subjects were 8,905 residents of nursing homes in Niigata, Japan (mean age, 84.3 years). Fracture histories were obtained from nursing home medical records. ADL levels were assessed by caregivers. Hip fracture diagnosis was based on hospital medical records. Subjects had fracture histories of upper limbs (5.0%), hip (14.0%), and nonhip lower limbs (4.6%). Among historical single fractures, only prior nonhip lower limbs significantly predicted subsequent fracture (adjusted hazard ratio, 2.43; 95% confidence interval (CI), 1.30-4.57). The stepwise method selected the best model, in which a combined historical fracture at upper limbs or nonhip lower limbs (adjusted hazard ratio, 2.14; 95% CI, 1.30-3.52), dependence, ADL levels, mobility, dementia, weight, and type of nursing home independently predicted subsequent hip fracture. A fracture history at upper or nonhip lower limbs, in combination with other known risk factors, is useful for the prediction of future hip fracture in institutional settings.

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.

A discrete fracture model for two-phase flow in fractured porous media

Gläser, Dennis; Helmig, Rainer; Flemisch, Bernd; Class, Holger

2017-12-01

A discrete fracture model on the basis of a cell-centered finite volume scheme with multi-point flux approximation (MPFA) is presented. The fractures are included in a d-dimensional computational domain as (d - 1)-dimensional entities living on the element facets, which requires the grid to have the element facets aligned with the fracture geometries. However, the approach overcomes the problem of small cells inside the fractures when compared to equi-dimensional models. The system of equations considered is solved on both the matrix and the fracture domain, where on the prior the fractures are treated as interior boundaries and on the latter the exchange term between fracture and matrix appears as an additional source/sink. This exchange term is represented by the matrix-fracture fluxes, computed as functions of the unknowns in both domains by applying adequate modifications to the MPFA scheme. The method is applicable to both low-permeable as well as highly conductive fractures. The quality of the results obtained by the discrete fracture model is studied by comparison to an equi-dimensional discretization on a simple geometry for both single- and two-phase flow. For the case of two-phase flow in a highly conductive fracture, good agreement in the solution and in the matrix-fracture transfer fluxes could be observed, while for a low-permeable fracture the discrepancies were more pronounced. The method is then applied two-phase flow through a realistic fracture network in two and three dimensions.

Psychological abuse: a variable deserving critical attention in domestic violence.

PubMed

O'Leary, K D

1999-01-01

Policy makers and researchers give psychological abuse considerably less attention than physical abuse in the partner abuse area. One reason for the relative neglect of psychological abuse is that there are difficulties in arriving at a common definition of psychological abuse that might be useful to both the mental health and legal professions. Another reason for the relative neglect of psychological abuse has been an implicit assumption that physical abuse exacts a greater psychological toll on victims than does psychological abuse. At the extreme level of physical abuse, this assumption seems defensible, but at levels of physical aggression that are most common in marriage and long-term relationships, psychological abuse appears to have as great an impact as physical abuse. Even direct ratings of psychological and physical abuse by women in physically abusive relationships indicate that psychological abuse has a greater adverse effect on them than physical abuse. Retrospective reports, longitudinal research, and treatment dropout research all provide evidence that psychological abuse can exact a negative effect on relationships that is as great as that of physical abuse. Finally, psychological abuse almost always precedes physical abuse, so that prevention and treatment efforts clearly need to address psychological abuse. Eight measures of various forms of psychological abuse that have reasonable psychometric properties and considerable construct validity are reviewed and a definition of psychological abuse in intimate relations is provided.

Prescription opioid abuse is a major public health concern and an ongoing epidemic in the United States. Loperamide is a widely available and inexpensive over-the-counter antidiarrheal with peripheral mu-opioid receptor activity. Online resources discuss the use of loperamide for the amelioration of withdrawal symptoms or recreational abuse. We describe the clinical course of 5 patients abusing loperamide, 3 of whom had life-threatening cardiac arrhythmias. In this observational case series, patients with cardiac arrhythmias or history of loperamide abuse with cardiac arrhythmias were identified; 5 patients were identified and 4 of the 5 patients were seen directly at the bedside. Clinical profile and outcome of patients is reported. We report 5 patients with history of loperamide abuse; 3 of the 5 patients had life-threatening cardiac arrhythmias. One of the patients experienced a second life-threatening arrhythmia after he resumed loperamide abuse. Loperamide levels were obtained in 4 of the 5 patients and were at least one order of magnitude greater than therapeutic concentrations. Discontinuation of loperamide resulted in complete resolution of cardiac conduction disturbances. This case series describes several patients with cardiac conduction abnormalities and life-threatening ventricular arrhythmias temporally related to loperamide abuse. With the recent efforts to restrict the diversion of prescription opioids, increasing abuse of loperamide as an opioid substitute may be seen. Toxicologists should be aware of these risks and we urge all clinicians to report such cases to FDA Medwatch(®).

Do abuse deterrent opioid formulations work?

Dart, Richard C; Iwanicki, Janetta L; Dasgupta, Nabarun; Cicero, Theodore J; Schnoll, Sidney H

We performed a systematic review to answer the question, "Does the introduction of an opioid analgesic with abuse deterrent properties result in reduced overall abuse of the drug in the community?" We included opioid analgesics with abuse deterrent properties (hydrocodone, morphine, oxycodone) with results restricted to the metasearch term "delayed onset," English language, use in humans, and publication years 2009-2016. All articles that contained data evaluating misuse, abuse, overdose, addiction, and death were included. The results were categorized using the Bradford-Hill criteria. We included 44 reports: hydrocodone (n = 7), morphine (n = 5), or oxycodone (n = 32) with Food and Drug Administration-approved Categories 1, 2, or 3 abuse deterrent labeling. The data currently available support the Hill criteria of strength (effect size), consistency (reproducibility), temporality, plausibility, and coherence. There was insufficient or no information available for the criteria of biological gradient, experiment, and analogy. We also assessed confounding factors and bias, which indicated that both were present and substantial in magnitude. Our analysis found that only oxycodone extended release (ER) had information available to evaluate abuse deterrence in the community. In Australia, Canada, and the United States, reformulation of oxycodone ER was followed by marked reduction in measures of abuse. The precise extent of reduced abuse cannot be calculated because of heterogeneous data sets, but the reported reductions ranged from 10 to 90 percent depending on the measure and the duration of follow-up.

The role of abuse-deterrent formulations in countering opioid misuse and abuse.

Pain is a prevalent, and due to the ageing population, increasing medical problem. Opioids are frequently prescribed to meet the unmet medical need. Unfortunately, with the increase in the legitimate use of opioids, there has been a corresponding increase in abuse. A practical way to retain the pain relief afforded by opioids while decreasing opportunities for abuse is to make it more difficult to extract the opioid from the product or to make it less desirable to do so by designing an abuse-deterrent formulation (ADF). We provide a brief overview of the strategies and early evidence related to opioid ADFs. Published and unpublished literature, websites, and other sources were searched for current opioid formulation options, including immediate-release and extended-release products. Each was summarized, reviewed and assessed. The strategies that have been used to design the current opioid ADFs involve one or more of four approaches: a physical barrier; incorporation of an opioid receptor antagonist (e.g. naloxone) that self-limits opioid action when taken in excess amount; inclusion of a noxious agent that is released during inappropriate use; or a pro-drug. Legitimate use of opioid analgesics carries with it certain risks, including the risk of abuse. The new ADFs utilize four major strategies and provide innovative additions to the armamentarium. They likely will become an important part of a comprehensive approach to limiting, although not eliminating, opioid misuse and abuse. © 2015 John Wiley & Sons Ltd.

This is the second of two volumes. The other volume (WL-TR-92-3015) is 'Causes of Failures of Shop Replaceable Units and Hybrid Microcircuits.' The objective of the Electronics Reliability Fracture Mechanics (ERFM) program was to develop and demonstrate a life prediction technique for electronic assemblies, when subjected to environmental stresses of vibration and thermal cycling, based upon the mechanical properties of the materials and packaging configurations which make up an electronic system. The application of fracture mechanics to microscale phenomena in electronic assemblies was a pioneering research effort. The small scale made the experiments very difficult; for example, the 1-mil-diameter bond wires in microelectronic devices are 1/3 the diameter of a human hair. A number of issues had to be resolved to determine whether a fracture mechanics modelling approach is correct for the selected failures; specifically, the following two issues had to be resolved: What fraction of the lifetime is spent in crack initiation? Are macro fracture mechanics techniques, used in large structures such as bridges, applicable to the tiny structures in electronic equipment? The following structural failure mechanisms were selected for modelling: bondwire fracture from mechanical cycling; bondwire fracture from thermal (power) cycling; plated through hole (PTH) fracture from thermal cycling. The bondwire fracture test specimens were A1-1 percent Si wires, representative of wires used in the parts in the modules selected for detailed investigation in this program (see Vol. 1 of this report); 1-mil-diameter wires were tested in this program. The PTH test specimens were sections of 14-layer printed wiring boards of the type used.

Workplace abuse: finding solutions.

The atmosphere within the work setting speaks volumes about your culture, and is often a primary factor in recruitment and retention (or turnover) of staff. Workplace tension and abuse are significant contributing factors as to why nurses are exiting workplaces--and even leaving the profession. Abuse can take many forms from inappropriate interpersonal communication to sexual harassment and even violence. Administrators should adopt a zero tolerance policy towards abusive communication. Addressing peer behavior is essential, but positive behavior must also be authentically modeled from the CNO and other nursing leaders. Raising awareness and holding individuals accountable for their behavior can lead to a safer and more harmonious work environment.

Substance abuse still remains one of the major problems in the world today, with millions of people abusing legal and illegal drugs. In addition, a billion people may also be infected with one or more infections. Both drugs of abuse and infections are associated with enormous burden of social, economic, and health consequences. This article briefly discusses a few medical consequences of drugs of abuse and infections such as human immunodeficiency virus, hepatitis C virus, psychiatric complications in hepatitis C infection, pharmacokinetic drug-drug interactions among medications used in the treatment of addiction and infections, and new drugs in development for the treatment of infections. Research is encouraged to study interactions between infections, drugs of abuse, and underlying pathophysiologic and molecular/genetic mechanisms of these interactions.

Elder abuse in Chinese populations: a global review.

PubMed

Dong, XinQi

2015-01-01

This review focuses on the epidemiology of elder abuse in the global Chinese population with respect to its prevalence, risk factors, and consequences, as well as the perceptions of elder abuse. Evidence revealed that elder abuse and its subtypes are common among the global Chinese population with prevalence ranging from 0.2% to 64%. Younger age, lower income levels, depression, cognitive impairment, and lack of social support were consistently associated with self-reported elder abuse. Caregiver burden was a constant risk factor for the proclivity to elder abuse by caregivers. The adverse health outcomes of elder abuse included suicidal ideation and psychological stress. Some primary research gaps exist: such as, lack of consistency in measurements and recall periods, insufficient studies on the causal relationships between potential risk factors and elder abuse, consequences of elder abuse, and possible interventions. In order to reduce the risk of elder abuse in the global Chinese population, collaboration is encouraged among researchers, health care professionals, social service providers, and policy makers.

Inhalant abuse of 1,1-difluoroethane (DFE) leading to heterotopic ossification: a case report

PubMed Central

Little, Jill; Hileman, Barbara; Ziran, Bruce H

2008-01-01

Background Heterotopic ossification (HO) is the formation of mature, lamellar bone within soft tissues other than the periosteum. There are three recognized etiologies of HO: traumatic, neurogenic, and genetic. Presently, there are no definitively documented causal factors of HO. The following factors are presumed to place a patient at higher risk: 60 years of age or older, male, previous HO, hypertrophic osteoarthritis, ankylosing spondylitis, diffuse idiopathic skeletal hyperostosis, prior hip surgery, and surgical risk factors. Case presentation A 33-year-old male, involved in a motor vehicle crash, sustained an irreducible acetabulum fracture/dislocation, displaced proximal humerus fracture, and an impacted pilon fracture. During the time of injury, he was intoxicated from inhaling the aerosol propellant used in "dust spray" cans (1,1-difluoroethane, C2H4F2). Radiographs identified rapid pathologic bone formation about the proximal humeral metaphysis, proximal femur, elbow, and soft tissue several months following the initial injury. Discussion The patient did not have any genetic disorders that could have attributed to the bone formation but had some risk factors (male, fracture with dislocation). Surgically, the recommended precautions were followed to decrease the chance of HO. Although the patient did not have neurogenic injuries, the difluoroethane in dusting spray can cause damage to the central nervous system. Signals may have been mixed causing the patient's body to produce bone instead of tissue to strengthen the injured area. Conclusion What is unusual in this case is the rate at which the pathological bone formation appeared, which was long outside the 4–6 week window in which HO starts to appear. The authors are not certain as to the cause of this rapid formation but suspect that the patient's continued abuse of inhaled aerosol propellants may be the culprit. PMID:18973696

Prescription Drug Abuse: From Epidemiology to Public Policy

PubMed Central

McHugh, R. Kathryn; Nielsen, Suzanne; Weiss, Roger D.

2014-01-01

Prescription drug abuse has reached an epidemic level in the United States. The prevalence of prescription drug abuse escalated rapidly beginning in the late 1990s, requiring a significant increase in research to better understand the nature and treatment of this problem. Since this time, a research literature has begun to develop and has provided important information about how prescription drug abuse is similar to, and different from the abuse of other substances. This introduction to a special issue of the Journal of Substance Abuse Treatment on prescription drug abuse provides an overview of the current status of the research literature in this area. The papers in this special issue include a sampling of the latest research on the epidemiology, clinical correlates, treatment, and public policy considerations of prescription drug abuse. Although much has been learned about prescription drug abuse in recent years, this research remains in early stages, particularly with respect to understanding effective treatments for this population. Future research priorities include studies on the interaction of prescription drugs with other licit and illicit substances, the impact of prescription drug abuse across the lifespan, the optimal treatment for prescription drug abuse and co-occurring conditions, and effective public policy initiatives for reducing prescription drug abuse.

Marshall, W N

1997-03-01

To describe the use of inpatient hospitalization for abused and neglected children living in a metropolitan area. Retrospective record review of abused and neglected children admitted in 1992 and 1993 to hospitals with 87% of metropolitan area pediatric admissions; comparison of these data with population, crisis nursery, and child protective services data. Thirty-four abused and neglected children were admitted to hospital, representing 0.3% (34/11,066; 95% confidence interval, 0%-1.2%) of pediatric admissions and 0.2% (34/19,950; 95% confidence interval, 0%-0.6%) of child protective services reports. This represents a rate of hospitalization for child abuse of 10 children (95% confidence interval, 0-46) per 100,000 child population per year. Seven hundred fifteen children were admitted to the crisis nursery by child protective services. Of those admitted to the hospital, 12 needed intensive care, 5 of whom died. Only 3 of 34 hospital-admitted children had private health insurance; 19 of 34 were younger than 1 year. Inpatient hospitalization for abuse represented a small fraction of total pediatric admissions and of child protective services reports. Comprehensive medical care for most abused children and medical education about child abuse must occur in outpatient settings.

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. PMID:28496390

Comorbid psychiatric and alcohol abuse/dependence disorders: psychosocial stress, abuse, and personal history factors of those in treatment.

De Bernardo, Gina L; Newcomb, Michael; Toth, Amanda; Richey, Gary; Mendoza, Richard

2002-01-01

Factors related to comorbid versus only substance disorders are essential to understanding and treating these complex problems. Medical records of sixty-nine inpatients at a private rehabilitation hospital in Southern California were reviewed to determine the associations between personal history factors and (1) comorbid psychiatric and substance abuse disorders and (2) participant's self-assessed progress in treatment. Results revealed significant differences between dual diagnosis patients (alcohol abuse/dependence and an affective disorder) and alcohol abuse/dependence only in regard to gender, previous diagnosis, length of illness, suicide attempts, psychotropic medication history, maternal emotional, physical and sexual abuse, paternal abuse, legal difficulties, and psychosocial stressors. No significant differences between substance abusing patients and dually diagnosed patients were found in terms of self-assessment of progress in treatment. Significant correlations were found between self-assessed progress in treatment and major depression (versus bipolar disorder), use of psychotropic medication, and less abuse from mother or primary caretaker. Identification of these personal history factors may be useful in developing and implementing treatment plans.

Physical, emotional and sexual child abuse are major problems in South Africa. This study investigates whether children know about post-abuse services, if they disclose and seek services, and what the outcomes of help-seeking behaviour are. It examines factors associated with request and receipt of services. Confidential self-report questionnaires were completed by adolescents aged 10-17 (n = 3515) in South Africa. Prevalence of frequent (>weekly) physical abuse was 7.4%, frequent emotional abuse 12.4%, and lifetime contact sexual abuse 9.0%. 98.6% could name one suitable confidante or formal service for abuse disclosure, but only 20.0% of abuse victims disclosed. Of those, 72% received help. Most common confidantes were caregivers and teachers. Of all abuse victims, 85.6% did not receive help due to non-disclosure or inactivity of services, and 14.4% received help: 4.9% from formal health or social services and 7.1% through community vigilante action. Emotional abuse, sexual abuse and female gender were associated with higher odds of help-seeking. While children in South Africa showed high knowledge of available services, access to and receipt of formal services among abused children was low. Notably fewer children received help from formal services than through community vigilante action. Urgent action is needed to improve service access for child abuse victims.

We report here a terminally ill patient with stomach cancer who developed a brief psychotic disorder mimicking cerebrovascular attack after a short episode of nasal bleeding. Close examination of the patient revealed that nasal bleeding was an event that symbolized deterioration of the general condition leading to death for the patient. A 77-year-old male, who was diagnosed as having stomach cancer and was receiving palliative care, presented with tremor and insomnia just after a short episode of nasal bleeding and showed reduced response to stimuli mimicking cerebrovascular attack. Laboratory data were unremarkable. The next day, catatonic behavior developed. He had no history of psychiatric illness or drug or alcohol abuse. After receiving haloperidol, psychiatric symptoms disappeared and he returned to the previous level of functioning within 3 days. The patient explained that he had seen a patient whose general condition deteriorated after nasal bleeding and regarded nasal bleeding as a symptom of deteriorating general condition leading to death and thereafter became afraid of the nasal bleeding. Although, nasal bleeding is common and usually not severe in medical settings, for the patient, it was an event that symbolized deterioration of the general condition leading to death. Brief psychotic disorder in cancer patients is rare in the literature, although patients receiving terminal care share various kinds of psychological burden. Medical staff in the palliative care unit should be aware of the psychological distress experienced by each patient and consider brief psychotic disorder as part of the differential diagnosis when patients show unexplained neurological-like and/or psychiatric symptoms.

Abused women: dispelling myths and encouraging intervention.

PubMed

King, M C; Ryan, J

1989-05-01

Our society abounds with myths and misperceptions in relation to the battering of women. These myths impede the identification of women who are experiencing violence and abuse, and inhibit appropriate intervention. Abuse is not too private a matter to assess for, nor does abuse affect only poor black or Hispanic women. No woman deserves to be beaten. Women do not like or seek out abuse. Abused women are courageous, competent women; what abused women have in common is that they are threatened and controlled by a male partner and live under the constant fear of violence and abuse. Raising one's consciousness about the victimization and oppression of women in our society, and uncovering the myths which leave practitioners powerless and ineffective agents of change for women are important tasks for health care providers. By focusing attention on this enormous health problem, clinicians can provide a leadership role in using health care responses that actually empower women to take control of their own lives.

Structure-Based Design of Inhibitors of Protein–Protein Interactions: Mimicking Peptide Binding Epitopes

PubMed Central

Pelay-Gimeno, Marta; Glas, Adrian; Koch, Oliver; Grossmann, Tom N

2015-01-01

Protein–protein interactions (PPIs) are involved at all levels of cellular organization, thus making the development of PPI inhibitors extremely valuable. The identification of selective inhibitors is challenging because of the shallow and extended nature of PPI interfaces. Inhibitors can be obtained by mimicking peptide binding epitopes in their bioactive conformation. For this purpose, several strategies have been evolved to enable a projection of side chain functionalities in analogy to peptide secondary structures, thereby yielding molecules that are generally referred to as peptidomimetics. Herein, we introduce a new classification of peptidomimetics (classes A–D) that enables a clear assignment of available approaches. Based on this classification, the Review summarizes strategies that have been applied for the structure-based design of PPI inhibitors through stabilizing or mimicking turns, β-sheets, and helices.

Androgen abuse in the community.

Melnik, Bodo C

2009-06-01

To provide information of the current prevalence of illicit use of androgens by individuals of the community. Prevalence of abuse of androgens in individuals of the general population has reached alarming dimensions. Use of androgens is no longer limited to competitive sports, but has spread to leisure and fitness sports, bodybuilding, and nonathletes motivated to increase muscular mass and physical attractiveness. Alarming studies from Germany demonstrated that members of the healthcare systems provide illegal androgens to 48.1% of abusers visiting fitness centers. The new trend to combine androgens with growth hormone, insulin, and insulinotropic milk protein-fortified drinks may potentiate health risks of androgen abuse. The use of androgens has changed from being a problem restricted to sports to one of public health concern. The potential health hazards of androgen abuse are underestimated in the medical community, which unfortunately contributes to illegal distribution of androgens. Both the adverse effects of current androgen abuse especially in young men as well as the chronic toxicity from past long-term abuse of now middle-aged men has to be considered as a growing public health problem. In the future, an increasing prevalence of androgen misuse in combination with other growth-promoting hormones and insulinotropic milk protein products has to be expected, which may have further promoting effects on the prevalence of chronic western diseases.

Gender differences in abused children with and without disabilities.

Sobsey, D; Randall, W; Parrila, R K

1997-08-01

Two questions were posed: (1) What are the proportions of boys and girls in various categories of substantiated child abuse? (2) Do the gender proportions differ for children with and without disabilities? Data collected by previous researchers from a demographically representative sample of U.S. child abuse reporting districts was analyzed. This included 1,249 case files involving 1,834 children. The number of girls and boys who did and did not have disabilities was identified for three age categories and for several categories of abuse. Chi-square analyses were used to determine whether there was a relationship between disability and gender for the various age and abuse categories. More boys were physically abused and neglected, but more girls were sexually abused. Boys with disabilities, however, were over-represented in all categories of abuse. Moreover, gender proportions among abused children with disabilities differed significantly from those found among other abused children. Although slightly more than half of abused children without disabilities were girls, 65% of abused children with disabilities were boys. Boys represented a significantly larger proportion of physically abused, sexually abused, and neglected children with disabilities than would be expected from their respective proportion of abused and neglected children without disabilities. Several possible explanations for the observed gender and disability status interaction are discussed.

Recent advancements in technology (e.g., social networking, texting) have created new ways for dating youth to relate to one another, including in abusive ways via "cyber dating abuse." Cyber dating abuse is a form of teen dating violence that overlaps with other types of abuse (e.g., psychological) but also has several unique characteristics. Given the phenomenon's limited presence in dating violence literature, we focus on identifying how experiencing cyber dating abuse relates to youths' individual behaviors and experiences (e.g., substance use, sexual activity), psychosocial adjustment, school connection, family relationships, and partner relationships. A total of 3,745 youth (52% female, 74% White) in three northeastern states participated in the survey and reported currently being in a dating relationship or having been in one during the prior year. We found that experiences of cyber dating abuse were most significantly correlated with being female, committing a greater variety of delinquent behaviors, having had sexual activity in one's lifetime, having higher levels of depressive symptoms, and having higher levels of anger/hostility. Further, cyber dating abuse appeared somewhat more strongly related to depressive symptoms and delinquency than did other forms of teen dating violence and abuse.

Fatigue (or stress) fracture of bone in military recruits has been recognized for many years. Most often it is a metatarsal bone that is involved but the tarsal bones, calcaneus, tibia, fibula, femur, and pelvis are occasionally affected. Reports of such fractures in the ribs, ulna and vertebral bodies may be found in the literature. In recent years, there has been increasing awareness of the occurrence of fatigue fractures in the civilian population. Weekend sportsmen, athletes in an early phase of training, and persons engaged in unaccustomed, repetitive, vigorous activity are potential victims of such a fracture. The signs and symptoms, roentgenographic findings, treatment and etiology of fatigue fractures are dealt with in this presentation. ImagesFigure 1.Figure 2.Figure 3.Figure 4.Figure 5.Figure 6.

Child sexual abuse is one of the main types of abuse still to be addressed within the field of education, yet the education system itself can serve as a primary tool for its prevention. A better understanding of teachers' knowledge and beliefs about child sexual abuse will allow us to establish key starting points from which to utilize the system for prevention. Four hundred and fifty teachers participated in this study, completing a questionnaire regarding their knowledge and beliefs about child sexual abuse. The study revealed that over half the teachers, 65.3% (n = 294), had never received any type of training in child sexual abuse education and that the majority were not familiar with methods of identifying child sexual abuse, 90.7% (n = 279). Various mistaken beliefs were identified among the participating teachers, such as pathological profiles of abusers, that the vast majority of child sexual abuse implies violent behavior, and that there cannot be abusers the same age as the victim. These results indicate that knowledge deficiencies do exist about child sexual abuse among teachers and highlight the need for training in this field.

A positive history of fractures in older patients with hip fracture is common. We determined the risk factors associated with a positive history of fractures and the profile of care in hip fracture patients. In the Break Study, we enrolled 1249 women aged ≥60 years, seeking care for a hip fracture. Baseline information included age, body mass index, lifestyle (smoking habit, alcohol consumption), patient's history of fracture after the age of 50 years, family history of fragility fracture and health status (presence of comorbidity, use of specific drugs, pre-fracture walking ability, type of fracture, time to surgery, type of surgery, osteoporosis treatment). In the multivariable model age, smoking, family history, treatment with antiplatelet, anticoagulants and anticonvulsants, were significant predictors of a positive history of fracture. More than 70% of patients underwent surgery more than 48 hours after admission. About 50% were discharged with a treatment for osteoporosis, but more than 30% only with calcium and vitamin D. In conclusion, factors associated with a positive history of fracture are the traditional risk factors, suggesting that they continue to have a negative impact on health even at older ages. Selected drugs, such as antiplatelet and anticoagulants, deserve further consideration as significant factors associated with fractures. Given that delay in surgery is a major cause of mortality and disability, while treatment for osteoporosis decreases significantly the risk of recurrent fractures and disability, interventions to modify these patterns of care are urgently needed.

Spontaneous motor entrainment to music in multiple vocal mimicking species.

Schachner, Adena; Brady, Timothy F; Pepperberg, Irene M; Hauser, Marc D

2009-05-26

The human capacity for music consists of certain core phenomena, including the tendency to entrain, or align movement, to an external auditory pulse [1-3]. This ability, fundamental both for music production and for coordinated dance, has been repeatedly highlighted as uniquely human [4-11]. However, it has recently been hypothesized that entrainment evolved as a by-product of vocal mimicry, generating the strong prediction that only vocal mimicking animals may be able to entrain [12, 13]. Here we provide comparative data demonstrating the existence of two proficient vocal mimicking nonhuman animals (parrots) that entrain to music, spontaneously producing synchronized movements resembling human dance. We also provide an extensive comparative data set from a global video database systematically analyzed for evidence of entrainment in hundreds of species both capable and incapable of vocal mimicry. Despite the higher representation of vocal nonmimics in the database and comparable exposure of mimics and nonmimics to humans and music, only vocal mimics showed evidence of entrainment. We conclude that entrainment is not unique to humans and that the distribution of entrainment across species supports the hypothesis that entrainment evolved as a by-product of selection for vocal mimicry.

We report the bone attenuation of ankle joint measured on computed tomography (CT) and the cause of injury in patients with ankle fractures. The results showed age- and gender-dependent low bone attenuation and low-energy trauma in elderly females, which suggest the osteoporotic features of ankle fractures. This study was performed to investigate the osteoporotic features of ankle fracture in terms of bone attenuation and cause of injury. One hundred ninety-four patients (mean age 51.0 years, standard deviation 15.8 years; 98 males and 96 females) with ankle fracture were included. All patients underwent CT examination, and causes of injury (high/low-energy trauma) were recorded. Mean bone attenuations of the talus, medial malleolus, lateral malleolus, and distal tibial metaphysis were measured on CT images. Patients were divided into younger age (<50 years) and older age (≥50 years) groups, and mean bone attenuation and causes of injury were compared between the two groups in each gender. Proportion of low-energy trauma was higher in the older age group than in the younger age group, but the difference was only significant in female gender (p = 0.011). The older age group showed significantly lower bone attenuation in the talus, medial malleolus, lateral malleolus, and distal tibial metaphysis than the younger age group in both genders. The older age group showed more complex pattern of fractures than the younger age group. With increasing age, bone attenuations tended to decrease and the difference of bone attenuation between the genders tended to increase in the talus, medial malleolus, lateral malleolus, and distal tibial metaphysis. Ankle fracture had features of osteoporotic fracture that is characterized by age- and gender-dependent low bone attenuation. Ankle fracture should not be excluded from the clinical and research interest as well as from the benefit of osteoporosis management.

Temporal bone fracture after mandibular trauma is thought to be rare, and its prevalence has not been reported in the literature. The purpose of this study was to investigate the prevalence of temporal bone fractures in patients with mandibular fractures and the relationship between temporal bone fractures and the mandibular fracture location using multidetector-row computed tomography (MDCT). A prospective study was performed in 201 patients with mandibular fractures who underwent 64-MDCT scans. The mandibular fracture locations were classified as median, paramedian, angle, and condylar types. Statistical analysis for the relationship between prevalence of temporal bone fractures and mandibular fracture locations was performed using χ(2) test with Fisher's exact test. A P-value < 0.05 was considered statistically significant. The percentage of cases with temporal bone fracture was 3.0 % of all patients with mandibular fractures and 19.0 % of those with multiple mandibular fractures of paramedian and condylar type. There was a significant relationship between the incidence of temporal bone fracture and the paramedian- and condylar-type mandibular fracture (P = 0.001). Multiple mandibular fractures of paramedian and condylar type may be a stronger indicator for temporal bone fractures. This study suggests that patients with mandibular fracture, especially the paramedian and condylar type, should be examined for coexisting temporal bone fracture using MDCT.

Child Abuse and Neglect in India.

PubMed

Seth, Rajeev

2015-08-01

India is home to the largest child population in the world, with almost 41 % of the total population under 18 y of age. The health and security of the country's children is integral to any vision for its progress and development. Doctors and health care professionals are often the first point of contact for abused and neglected children. They play a key role in detecting child abuse and neglect, provide immediate and longer term care and support to children. Despite being important stakeholders, often physicians have a limited understanding on how to protect these vulnerable groups. There is an urgent need for systematic training for physicians to prevent, detect and respond to cases of child abuse and neglect in the clinical setting. The purpose of the present article is to provide an overview of child abuse and neglect from a medical assessment to a socio-legal perspective in India, in order to ensure a prompt and comprehensive multidisciplinary response to victims of child abuse and neglect. During their busy clinical practice, medical professionals can also use the telephone help line (CHILDLINE telephone 1098) to refer cases of child abuse, thus connecting them to socio-legal services. The physicians should be aware of the new legislation, Protection of Children from Sexual Offences (POCSO) Act, 2012, which requires mandatory reporting of cases of child sexual abuse, failing which they can be penalized. Moreover, doctors and allied medical professionals can help prevent child sexual abuse by delivering the message of personal space and privacy to their young patients and parents.

False allegations of abuse and Munchausen syndrome by proxy.

Meadow, R

1993-01-01

Fourteen children from seven families are reported for whom false allegations of abuse were made by the mother. Twelve children were alleged to have incurred sexual abuse, one both sexual and physical abuse, and one physical abuse alone. Thirteen of the children had incurred, or were currently victims of, factitious illness abuse invented by the mother. The one child with no history of factitious illness abuse had a sibling who had incurred definite factitious illness abuse. The false allegations of abuse did not occur in the context of parental separation, divorce, or custody disputes concerning the children. They occurred in the context of Munchausen syndrome by proxy abuse. The age of the children, 3 to 9 years, was older than the usual age for Munchausen syndrome by proxy abuse. The mother was the source of the false allegations and was the person who encouraged or taught six of the children to substantiate allegations of sexual abuse. PMID:8503664

Pediatric maxillofacial fractures.

Spring, P M; Cote, D N

1996-05-01

Maxillofacial trauma in the pediatric population is a relatively infrequent occurrence. Studies have demonstrated consistently that 5% of all facial fractures occur in children. The low percentage of facial fractures in this age group has been attributed, in part, to the lack of full pneumatization of the sinuses until later in childhood. Review of the literature indicates that boys are more commonly affected than girls and that the majority of pediatric facial fractures occur in children between 6 and 12 years of age. Motor vehicle accidents, falls, and blunt trauma are responsible for the largest number of pediatric facial fractures. The most common site of facial fracture is the nose and dentoalveolan complex, followed by the mandible, orbit, and midface in most pediatric cohorts. Management of the mandible is often conservative owing to the high percentage of isolated condylar fractures in children. Open reduction and internal fixation of pediatric facial fractures is indicated in complex mandible, midface, and orbital fractures. The effect of rigid fixation on facial skeleton growth is not completely understood.

Substance Abuse and Disability.

Subtypes of cocaine abusers.

We have characterized five subtypes of cocaine abusers on the basis of clinical presentation, family history data, and response to specific treatment interventions. These include depressed patients who value the euphorigenic effects of the drug, patients with bipolar or cyclothymic disorder who use cocaine to augment manic or hypomanic symptoms or to alleviate depression, adults with ADD, residual type, who find that cocaine has a paradoxical effect of increasing attention span and decreasing motor restlessness, patients with narcissistic and borderline personality disorders who use cocaine for its social prestige and because it bolsters self-esteem, and patients with antisocial personality disorder who use cocaine as part of an overall pattern of antisocial behavior. Although not all cocaine abusers fit neatly into these categories, careful psychiatric evaluation and subtyping is essential in designing a specific treatment program for these patients. As the prevalence rate of cocaine abuse increases, studies that examine the efficacy of various treatment approaches for specific subtypes of cocaine abusers will be essential. It is hoped that our work will be a step in that direction.

Childhood abuse, alexithymia and personality disorder.

PubMed

Berenbaum, H

1996-12-01

I examined the relationships among childhood abuse, alexithymia, and personality disorder. Participants were 60 adults who were receiving outpatient psychotherapy. Both the participants and their therapists used the Toronto Alexithymia Scale to provide independently information concerning the client's level of alexithymia. The therapists provided information concerning DSM-III-R personality disorder diagnoses, and participants completed portions of the Personality Diagnostic Questionnaire-Revised. Information concerning childhood abuse history was obtained from the therapists. As expected, childhood abuse, alexithymia, and personality disorder were all associated with each other. The abilities to identify and communicate emotions were differentially associated with childhood abuse and personality disorder.

This study explored cultural and gender perspectives of abuse on condom negotiation behaviors for AIDS prevention among Mexican-American women in abusive intimate relationships. A convenience sample of 20 abused women participated in the study. Data were collected through a demographic questionnaire and audiotaped responses to a semistructured interview guide. Content analysis using QSR NUDIST was used to analyze the verbatim transcriptions of all participant interviews. The predominant category, "He always got his way," was developed in response to the content of the verbatim transcriptions. The category was further expanded to include the self-descriptive subcategories of "He beat me," "He made me feel bad," and "He forced me." Through content analysis, a relationship between abuse by male sexual partners and condom negotiation for AIDS prevention was identified. Trustworthiness of the data collection and analysis was established through methods suggested by Lincoln and Guba.

Presented is a case of incarcerated paracaecal hernia mimicking acute appendicitis. The clinical scenario highlights the need for a high index of suspicion in the management of patients with localised peritonism even in the absence of obstructive symptoms and the presence of normal laboratory markers of inflammation.Whilst computed tomography might offer a pre-operative diagnosis, in such a low-risk patient laparoscopy offers the combined advantages of immediate diagnosis and definitive treatment of acute pathology.

BUPRENORPHINE ABUSE IN INDIA : AN UPDATE

PubMed Central

Sharma, Yogesh; Mattoo, S.K.

1999-01-01

This study reviews the available Indian literature on buprenorphine abuse. Buprenorphine was introduced in 1986; the abuse, first noticed in 1987, increased rapidly till 1994, and then decreased gradually. Initiated through other addicts and medical practitioners, the abuse was mostly as a cheap, easily and legally available substitute for opioids. The typical young adult male abuser used an intravenous cocktail with diazepam, pheneramine or promethazine for a better kick. The withdrawal syndrome was typical of the opioids and without an expected delayed onset. Complications of pseudoaneurysm and recurrent koro in repeated withdrawal were reported. Buprenorphine as a detoxifying agent for opioids reportedly gave better symptom control in the first week but high rates of dependence induction were reported. The Indian data tends to caution against the Western enthusiasm to use buprenorphine for detoxification or maintenance of opioid abusers. PMID:21455379

Population studies suggest that rib fractures are associated with a reduction in bone mass. While much is known about the predictive risk of hip, spine and distal forearm fracture on the risk of future fracture, little is known about the impact of rib fracture. The aim of this study was to determine whether a recalled history of rib fracture was associated with an increased risk of future limb fracture. Men and women aged 50 years and over were recruited from population registers in 31 European centres for participation in a screening survey of osteoporosis (European Prospective Osteoporosis Study). Subjects were invited to complete an interviewer-administered questionnaire that included questions about previous fractures including rib fracture, the age of their first fracture and also the level of trauma. Lateral spine radiographs were performed and the presence of vertebral deformity was determined morphometrically. Following the baseline survey, subjects were followed prospectively by annual postal questionnaire to determine the occurrence of clinical fractures. The subjects included 6,344 men, with a mean age of 64.2 years, and 6,788 women, with a mean age of 63.6 years, who were followed for a median of 3 years (range 0.4-5.9 years), of whom 135 men (2.3%) and 101 women (1.6%) reported a previous low trauma rib fracture. In total, 138 men and 391 women sustained a limb fracture during follow-up. In women, after age adjustment, those with a recalled history of low trauma rib fracture had an increased risk of sustaining 'any' limb fracture [relative hazard (RH)=2.3; 95% CI 1.3, 4.0]. When stratified by fracture type the predictive risk was more marked for hip (RH=7.7; 95% CI 2.3, 25.9) and humerus fracture (RH=4.5; 95% CI 1.4, 14.6) than other sites (RH=1.6; 95% CI 0.6, 4.3). Additional adjustment for prevalent vertebral deformity and previous (non-rib) low trauma fractures at other sites slightly reduced the strength of the association between rib fracture and

To determine whether convictions and sentencing differ between child abuse homicide cases and adult homicide cases and to identify characteristics of the victim, suspect, or crime that influence conviction and sentencing results. Retrospective case review. Homicide data abstracted from the National Violent Death Reporting System in Utah. All deaths classified as homicide in Utah between January 1, 2002, and December 31, 2007. Judicial processing of homicide cases for conviction and sentencing results. Conviction rate, level of felony conviction, and severity of sentencing for suspects of child abuse homicide vs adult homicide. Utah had 373 homicide victims during the study period; 52 cases were child abuse homicide. Among 211 homicide cases with an identified suspect, conviction rates for child abuse homicide (88.2%) and adult homicide (83.0%) were similar (risk ratio, 1.0; 95% confidence interval [CI], 0.8-1.4). There were no significant differences in level of felony conviction (adjusted risk ratio, 0.8; 95% CI, 0.4-1.3) or severity of sentencing (adjusted risk ratio, 0.8; 95% CI, 0.5-1.5) for suspects of child abuse homicide vs adult homicide. Among child abuse homicide cases, no demographic factor was significantly associated with felony conviction results. Suspects of child abuse homicide are convicted at a rate similar to that of suspects of adult homicide and receive similar levels of felony conviction and severity of sentencing.

Tapentadol, a Schedule II opioid with a combination of µ-opioid activity and norepinephrine reuptake inhibition, is used for the management of moderate to severe acute and chronic pain. Its dual mechanism of action is thought to reduce opioid-related side effects that can complicate pain management. Since approval, tapentadol has been tracked across multiple outcomes suggesting abuse liability, and a pattern of relatively low, although not absent, abuse liability has been found. This retrospective cohort study further details the abuse liability of tapentadol as an active pharmaceutical ingredient (API) when immediate-release as well as extended-release formulations were on the market together (fourth quarter of 2011 to second quarter of 2016). Tapentadol (API) was compared with tramadol, hydrocodone, morphine, oxycodone, hydromorphone, and oxymorphone across Poison Center, Drug Diversion, and Treatment Center Programs Combined data streams from the Researched Abuse, Diversion and Addiction-Related Surveillance system. Findings suggest the public health burden related to tapentadol to date is low, but present. Event rates of abuse per population-level denominators were significantly lower than all other opioids examined. However, when adjusted for drug availability, event rates of abuse were lower than most Schedule II opioids studied, but were not the lowest. Disentangling these 2 sets of findings further by examining various opioid formulations, such as extended-release and the role of abuse-deterrent formulations, is warranted. This article presents the results from an examination of tapentadol API across the Researched Abuse, Diversion and Addiction-Related Surveillance System: a broad and carefully designed postmarketing mosaic. Data to date from Poison Center, Drug Diversion, and Treatment Centers combined suggest a low, but present public health burden related to tapentadol. Copyright © 2018. Published by Elsevier Inc.
